TECHNICAL FIELD

The present application relates to the field of treadmill, in particular, to a walking pad.

BACKGROUND

To facilitate transportation and reduce home storage space, many walking pads in the prior art are designed with foldable front and rear walking pads. The front and rear walking pads can be folded by rotating 180° relative to each other through folding connection structures disposed at both sides. When in use, the front and rear walking pads can be rotated 180° in the opposite direction to unfold them into a flat running state.

The foldable walking pads in the prior art still have some common shortcomings. After the front and rear walking pads are unfolded, it is difficult to keep the top surfaces of the two walking pads on the same plane, which makes the junction of the front and rear walking pads feel uneven. In order to solve this problem, a generally used solution is to lay a thicker layer of flexible material on the front and rear walking pads to eliminate the feeling of unevenness. However, the thickness of the flexible material layer is relatively complicated, which makes the manufacturing process relatively complicated and increases the costs.

As shown in FIGS. 1-8, in order to facilitate transportation and reduce home storage space, the present application provides a walking pad 1, including an alignment structure 2, a first walking pad 11 and a second walking pad 12 which is foldable onto the first walking pad 11. The alignment structure 2 includes a first matching element 21 connected to the first walking pad 11 and a second matching element 22 connected to the second walking pad 12, where the first matching element 21 is configured to be able to abut against the second matching element 22. A first abutting surface 212 of the first matching element 21 is matched with a second abutting surface 222 of the second matching element 22, and a top surface of the first walking pad 11 and a top surface of the second walking pad 12 are on a same plane when the first matching element 21 abuts against the second matching element 22.

When a folded walking pad 1 is unfolded, the first abutting surface 212 of the first matching element 21 and the second abutting surface 222 of the second matching element 22 can slide to completely match and abut each other, thereby realizing the automatic guidance and alignment of the first walking pad 11 and the second walking pad 12, so that the top surface of the first walking pad 11 and the top surface of the second walking pad 12 are kept on the same horizontal plane. The feeling of integrity between the first walking pad 11 and the second walking pad 12 is enhanced, the feeling of unevenness between these two adjacent walking pads in the prior art is eliminated. Therefore, the user's foot feelings and experience are improved, and the similarity between the feelings of using the walking pad 1 and the feelings of running on the ground is also enhanced. In addition, the manufacturing process is relatively simple, and the cost is relatively saved, and the service life of the walking pad 1 can be extended.

In some embodiments, as shown in FIGS. 3-4, where FIG. 4 omits some parts such as protective housings, a running belt, a passive roller, and running boards in order to show more clearly, the first matching element 21 may be one strip and the second matching element 22 may be one strip. The first matching element 21 is arranged at one end, which is closer to the second walking pad 12, of the first walking pad 11 and extends along a width direction of the first walking pad 11, and the second matching element 22 is arranged at one end, which is closer to the first walking pad 11, of the second walking pad 12 and extends along a width direction of the second walking pad 12. Specifically, a ratio of a length of the first matching element 21 to a width of the first walking pad 11 may be in a range from 0.7 to 0.9 or a range of 0.8 to 0.9, and a ratio of a length of the second matching element 22 to a width of the second walking pad 12 may be a range from 0.7 to 0.9 or a range of 0.8 to 0.9. Furthermore, the length of the first matching element 21 may be the same as or different from the length of the second matching element 22.

In some embodiments, the first matching element 21 may include a plurality of first strips, the second matching element 22 may include a plurality of second strips (not shown in the drawings). The plurality of first strips are arranged at intervals at one end, which is closer to the second walking pad 12, of the first walking pad 11, and the plurality of first strips extend along a width direction of the first walking pad 11 and are arranged on a same straight line. The plurality of second strips are arranged at intervals at one end, which is closer to the first walking pad 11, of the second walking pad 12, and the plurality of second strips extend along a width direction of the second walking pad 12 and are arranged on a same straight line. At least one first strip is arranged to match one second strip. Specifically, lengths and intervals of the plurality of first strips may be the same or different, and intervals of the plurality of first strips may be the same or different. Lengths and intervals of the plurality of second strips may be the same or different, and intervals of the plurality of second strips may be the same or different. The lengths of the first strip and the lengths of the second strip may be the same or different, and a number of the first strips and a number of the second strips may be the same or different. With the above arrangements, the cooperation between the first abutting surface 212 and the second abutting surface 222 can be more flexible.

In some embodiments, the first matching element 21 is fixed to a bottom of the first walking pad 11 by a plurality of first longitudinal rods 114, and the second matching element 22 is fixed to a bottom of the second walking pad 12 by a plurality of second longitudinal rods 124. In a possible implementation, as shown in FIG. 1 and FIG. 2, an inner side surface of the first matching element 21 is fixed to the bottom of the first walking pad 11 by three first longitudinal rods 114, and an inner side surface of the second matching element 22 is fixed to the bottom of the second walking pad 12 by three second longitudinal rods 124. The above arrangements enable the first matching element 21 and the second matching element 22 to achieve stable connections with the corresponding walking pad, and can save connection materials to a certain extent and reduce the overall weight of the walking pad for transportation.

In order to make the first abutting surface 212 of the first matching element 21 and the second abutting surface 222 of the second matching element 22 match each other, the shapes of the first abutting surface 212 and the second abutting surface 222 match each other, and the first abutting surface 212 and the second abutting surface 222 are in surface contact when abutting. Specifically, the first abutting surface 212 of the first matching element 21 may be a V-shaped concave surface, and the second abutting surface 222 of the second matching element 22 may be a V-shaped convex surface; the first abutting surface 212 of the first matching element 21 may be an U-shaped concave surface, and the second abutting surface 222 of the second matching element 22 may be an U-shaped convex surface; the first abutting surface 212 of the first matching element 21 may be a semicircular concave surface, and the second abutting surface 222 of the second matching element 22 may be a semicircular convex surface; the first abutting surface 212 of the first matching element 21 may be a W-shaped concave surface, and the second abutting surface 222 of the second matching element 22 may be a W-shaped convex surface, etc.

In some embodiments, the shapes of the first abutting surface 212 and the second abutting surface 212 may not be completely matched. For example, the first abutting surface 212 and the second abutting surface 212 may be in line contact. In a possible implementation, the first abutting surface 212 may be a V-shaped concave surface, and the second abutting surface 222 may be an arc-shaped convex surface that can be accommodated by the second abutting surface 212, such as a U-shaped convex surface or a semicircular convex surface.

In some embodiments, the first walking pad 11 and the second walking pad 12 are connected by two folding connection structures 3, and the two folding connection structures 3 are symmetrically arranged on both sides of the walking pad 1. Specifically, the first walking pad 11 includes a first running board 112, a first cross rod 113 and two first side rods 111 arranged on both sides of the first running board 112, the first cross rod 113 is connected to the two first side rods 111, and the first matching element 21 is connected to the first crossbar 113 by the plurality of first longitudinal rods 114. The second walking pad 12 includes a second running board 122, a second cross rod 123 and two second side rods 121 arranged on both sides of the second running board 122, the second crossbar 123 is connected to the two second side rods 121, and the second matching element 22 is connected to the second crossbar 123 by the plurality of second longitudinal rods 124. One first side rod 111 and one second frame 121 on a same side are connected by a folding connection structure 3. The first running board 112 is connected between the two first side rods 111 by the first cross rod 113, and the second running board 122 is connected between the two second side rods 121 by the second cross rod 123. The first running board 112 and the second running board 122 are provided with a running belt 14 on their outer rings. The first walking pad 11 and the second walking pad 12 can be folded by relatively rotating 180° via the folding connection structures 3 on both sides. When users are going to use the walking pad 1, the first walking pad 11 and the second walking pad 12 can be relatively rotated 180° in the opposite direction to unfold and flatten the first walking pad 11 and the second walking pad 12 for the user to run.
