Technical Field
[0001] This utility model relates to the field of snowboard binding design, specifically a snowboard binding with shock absorption function. Background Technology
[0002] With the globalization of winter sports and the rapid development of professional competitions, the safety and comfort of skiing have become the focus of industry attention. Although traditional ski bindings have basic release functions (such as TOE / HEEL adjustment and torque threshold control), users often have to endure a large impact when performing high-speed freestyle tricks. At this time, users usually use special movements to reduce the impact effect, but such movements have limited effectiveness. Therefore, it is necessary to improve ski bindings.
[0003] The main function of traditional ski bindings is to mechanically fasten ski boots to skis and actively release them when subjected to external forces exceeding a threshold to reduce the risk of injury. However, existing bindings generally adopt a rigid structure design and lack an effective cushioning mechanism. Although this design can ensure power transmission efficiency, in complex terrain (such as bumpy snow surfaces, jumping landings) or sudden collision scenarios, the ground reaction force will be directly transmitted through the skis to the athlete's lower limb joints, causing severe impact on the knees, ankles and other parts. Long-term accumulation can easily lead to chronic injuries, or even acute fractures or ligament tears. With the popularization of skiing and the increasing safety standards of professional competitions, the development of bindings with controllable shock absorption functions has become an urgent need for the industry.

The sliding crossbar is engaged with the front spring plate and also with the rear spring plate. The sliding crossbar is used to adjust the preload of the front and rear spring plates, thereby adjusting the buffer stroke and buffer force of the front and rear spring plates.
[0010] Furthermore, a rear cavity is provided on one side of the bottom edge guard plate. A damper for buffering the spring rebound force is provided in the rear cavity. One end of the damper is fixedly connected to the inner wall of the rear cavity. A damping screw for adjusting the damping stiffness of this invention is provided in the rear cavity. The damping screw is rotatably connected to the bottom edge guard plate. A damping turntable is fixedly installed at the end of the damping screw outside the rear cavity.
[0011] Furthermore, an adjusting plate is slidably mounted on the outer wall of the damper, the adjusting plate is slidably connected to the inner wall of the rear cavity, the adjusting plate is threadedly connected to the damping screw, an adjusting spring is fixedly mounted on the adjusting plate, a sliding plate is fixedly mounted on the other end of the adjusting spring, the sliding plate is slidably connected to the inner wall of the rear cavity, and the sliding plate is fixedly connected to the moving end of the damper.

A front spring plate 204 is fixedly installed on the side of the rotating plate 203 near the bottom plate 201. The front spring plate 204 is arc-shaped. One end of the front spring plate 204 is fixed to the rotating plate 203 by bolts. In addition, the connection between the front spring plate 204 and the rotating plate 203 can also be welded. A front support spring 205 is fixedly installed on the other end of the front spring plate 204. The other end of the front support spring 205 is fixedly connected to the rotating plate 203.

[0036] Example 4:
[0037] This embodiment further elaborates on the rotating plate 203 in Embodiment 3, specifically as follows: Figures 4 to 6 As shown, a fixed circular plate 212 is rotatably installed inside the rotating plate 203. The fixed circular plate 212 is provided with bolt holes and a special card interface. The fixed circular plate 212 is fixedly connected to the single plate through bolts and the special card interface. A limiting plate 211 is slidably installed outside the fixed circular plate 212. The limiting plate 211 and the fixed circular plate 212 are engaged by a locking tooth. The limiting plate 211 is slidably connected to the bottom surface of the rotating plate 203. An angle screw 210 is threadedly installed on the limiting plate 211. The angle screw 210 is rotatably installed on the rotating plate 203. A rotating dial on the angle screw 210 is located on one side of the rotating plate 203 to facilitate the user to rotate the angle screw 210.
[0038] Working principle of this utility model: When using this utility model, firstly, it is fixed to the single board by bolts and special clip interfaces. When fixing this utility model to the single board, attention should be paid to the tilt of the utility model during installation. Generally, the installation tilt varies from person to person and can be adjusted after the shoe body and this utility model are fixed.
[0039] Next, the user places the shoe body between the sole 20 and the bottom edge plate 10, so that the bottom surface of the shoe body contacts the surface of the sole plate 201 in the sole 20. Then, the shoe body is fixed to the bottom edge plate 10 and the sole 20 by the shoe strap 40. At this time, it should be noted that when binding the shoe body, the user's lower leg needs to contact the back plate 30. After binding is completed, the tilt angle of this utility model on the single plate can be adjusted.
[0040] When adjusting the inclination angle of the sole 20 on the single plate, the two devices are generally set at an outward or parallel angle. There is also a case where one foot is parallel and the other at a special angle. In this case, the rotating dial on the angle screw 210 can be rotated, causing the angle screw 210 to drive the limiting plate 211 to slide at the bottom of the rotating plate 203. This disengages the limiting plate 211 from the fixed circular plate 212, which is now fixed to the single plate. After the engagement between the limiting plate 211 and the fixed circular plate 212 disengages, the components on the rotating plate 203 can rotate relative to the single plate, allowing adjustment of the shoe's angle relative to the single plate. After adjustment, the rotating dial on the angle screw 210 is rotated in the opposite direction to return the limiting plate 211 to its initial position, re-engaging the engagement between the limiting plate 211 and the fixed circular plate 212. This fixes the rotating plate 203 to the single plate.
[0041] In practical use, if the single plate is impacted, due to inertia, the human body and the bottom plate 201 of the bottom guard plate 202 will press downwards. Simultaneously, the front spring plate 204, the middle support spring 207, and the rear spring plate 208 between the bottom plate 201 and the rotating plate 203 will be compressed. These components then act as a buffer. During this buffering process, it should be noted that the sliding plate 106 will also move along with the rear spring plate 208, causing the adjusting spring 105 in the rear cavity to also contribute to the buffering effect, thereby reducing the impact on the single plate. The purpose of damping the human body during the cushioning operation of the front spring plate 204 and rear spring plate 208 is to prevent the rebound of the front spring plate 204 and rear spring plate 208 from being too fast. The damper 103 in this utility model will play a role in slowing down the rebound. The specific operation of the damper 103 can be referred to the damper design in the motorcycle shock absorber. By changing the size of the channel for oil return in the damper 103, the oil can be allowed to return slowly, thereby changing the rebound stroke of the front spring plate 204 and rear spring plate 208, thereby improving the comfort of using this utility model. The materials of the front spring plate 204 and rear spring plate 208 can be changed or replaced according to actual needs.
[0042] During snowboarding, the front spring plate 204 and rear spring plate 208 can be adjusted according to different intensities or speeds. Specifically, the user rotates the damping dial 101, causing the damping screw 102 to rotate. This drives the adjusting plate 104 to slide within the damper 103 and the rear cavity. When the adjusting plate 104 moves closer to the sliding plate 106, it compresses the adjusting spring 105. This compression transmits force to the sliding plate 106, causing it to move along with the sliding bar 206. Thus, the front spring plate 204 and rear spring plate 208 can be adjusted by moving the sliding bar 206. When the pre-pressure is applied, the shock absorption and cushioning function of this invention will be weakened. Under these circumstances, not only is the cushioning stroke smaller during movement, but the cushioning effect will also be less noticeable when the impact force is small. Conversely, by rotating the damping turntable 101 in the opposite direction, the space of the cushioning cavity can be increased through the above steps, thereby releasing the state of the front spring plate 204. At this time, the shock absorption and cushioning is more comfortable and sensitive. By changing the cushioning situation of the front spring plate 204 and the rear spring plate 208, this invention can adapt to different environments without changing the materials of the front spring plate 204 and the rear spring plate 208. At the same time, the user's own weight is also a factor affecting the front spring plate 204 and the rear spring plate 208. Users of different weights can also adjust according to the specific situation during use.
[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
