Description

Technical Field

[0001] This utility model relates to the technical field of bionic equipment, and in particular to a shock-absorbing support device for the legs of a bionic device. Background Technology

[0002] Bionic devices are technological devices designed and manufactured to mimic the structure, function, behavior, or physiological mechanisms of living organisms. The core logic is "learning from nature"—drawing inspiration from the efficient adaptive capabilities (such as movement, perception, and protection) that organisms have developed over millions of years of evolution to address the shortcomings of traditional devices in terms of flexibility, adaptability, and energy efficiency. Ultimately, they achieve technological applications that are "more efficient, more environmentally friendly, and more suited to specific scenarios," widely covering fields such as industry, medicine, scientific research, and daily life. Bionic robots are a relatively common type of bionic device. Bionic robots come in many shapes and sizes, some resembling humans and others animals.

[0003] To address the aforementioned issues, a search revealed a frameless, front-drive, vortex-flush one-piece toilet, disclosed in patent publication number CN118182676A. The patent states that "bionic robots" refer to robots that mimic biological organisms and perform tasks based on their characteristics. The goal is to achieve specific tasks or functions by imitating the structure, function, and behavior of biological systems. These robots may possess the appearance, movement, perception, and cognitive abilities of living organisms, enabling them to perform tasks in complex environments, such as exploring unknown areas or carrying out rescue missions. In the prior art, application publication number CN1178642... Chinese invention patent 70A discloses a six-legged insect-like jumping robot, including a torso. Forelimbs, midlimbs, and hindlimbs are arranged sequentially from front to back on both sides of the torso. A drive mechanism is provided on the torso. The drive mechanism includes a stop unit and a trigger unit connected by transmission. The stop unit is used to limit the forelimbs, midlimbs, and hindlimbs after they have completed accumulating power. The trigger unit is used to release the stop unit from limiting the forelimbs, midlimbs, and hindlimbs, thereby realizing a jumping action. The multi-legged bionic robot according to embodiments of the present invention has the following beneficial effects: 1. The main body of this device is composed of several support brackets connected sequentially, forming a multi-level chain structure. Multiple attitude adjustment modules are installed on these support brackets to adjust their rotation angles, allowing them to lift upwards when traversing obstacles. This enhances the obstacle avoidance flexibility of the device and overcomes the shortcomings of poor obstacle avoidance flexibility in existing technologies. 2. By installing several attitude adjustment modules on the support brackets and a displacement module on each side of each support bracket, this device... When moving downhill, the device can adjust its overall posture into a circular or chain-like structure to facilitate rolling on the downhill surface, thereby increasing its moving speed, saving energy consumed when moving downhill, and enhancing its practicality; 3. By setting a buffer component in the inner cavity of the main tibia to cushion the support frame, the device improves its stability when rolling on downhill surfaces. However, the springs in the support structure of the legs of existing bionic robots weaken in shock absorption after long-term use, and the shock-absorbing springs have a short service life and are very troublesome to replace.

[0004] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5This utility model provides a technical solution: a bionic equipment leg shock absorption support device, including a support leg 1; One end of the support leg 1 is provided with a shock-absorbing mechanism 2, and the other end of the shock-absorbing mechanism 2 is provided with an adjustment mechanism 3; The shock absorption mechanism 2 includes a connecting seat 201. A movable plate 202 is provided on one side of the connecting seat 201. A first connecting rod 203 is installed on one side surface of the movable plate 202. A support block 204 is provided on one side of the connecting seat 201. First auxiliary rods 205 are installed on both sides of the support block 204. A connecting ring 206 is sleeved on the outer wall of the first auxiliary rod 205. An installation ring 207 is connected to one side of the connecting ring 206. A first fixing block 208 is installed on the outer wall of the installation ring 207. A second fixing block 208 is installed on the outer wall of the connecting ring 206. Block 209, a first shock-absorbing spring 210 is installed on one side surface of mounting ring 207, a support plate 211 is installed on the outer wall of connecting ring 206, a support frame 212 is provided at one end of support plate 211, a lifting plate 213 is provided at the other end of support frame 212, a buffer plate 214 is installed on one side surface of lifting plate 213, and a support leg 1, connecting seat 201, moving plate 202, first connecting rod 203, support block 204, first auxiliary rod 205, connecting ring 206, mounting ring 207, and first fixing block 208 are connected. The arrangement of the second fixed block 209, the first damping spring 210, the support plate 211, the support frame 212, the lifting plate 213, and the buffer plate 214 allows the movement of the moving plate 202 to be adjusted by rotating the double-acting screw 301 when the elastic force of the first damping spring 210 weakens. This causes both moving plates 202 to move simultaneously toward the support block 204, reducing the deformation of the first damping spring 210 and thus ensuring its elastic force. This can extend the service life of the first damping spring 210 to a certain extent. When the movable plate 202 cannot guarantee the elasticity of the first damping spring 210, the first damping spring 210 needs to be replaced. At this time, remove the bolts and nuts between the first fixing block 208 and the second fixing block 209. The two mounting rings 207 can be separated from the connecting ring 206 and the movable plate 202 respectively. Finally, pull the movable plate 202 so that the movable plate 202 carries the first connecting rod 203 away from the first auxiliary rod 205. In this way, the mounting ring 207 and the first damping spring 210 can be quickly disassembled and installed.

[0018] Furthermore, the first auxiliary rod 205 is sleeved on the outer wall of the first connecting rod 203, and each end of the first shock-absorbing spring 210 is provided with an installation ring 207.

[0019] Furthermore, a bidirectional screw 301 is provided at one end of the connecting seat 201, a ball nut seat 302 is sleeved on the outer wall of the bidirectional screw 301, a connecting block 303 is installed on the outer wall of the ball nut seat 302, a second connecting rod 304 is installed on one side surface of the moving plate 202, a sliding groove 305 is opened on one side surface of the buffer plate 214, a slider 306 is provided inside the sliding groove 305, a second auxiliary rod 307 is installed on one side surface of the slider 306, a second shock-absorbing spring 308 is installed on one side surface of the moving plate 202, and a rotating plate 309 is installed at one end of the bidirectional screw 301. Through the adjustment mechanism 3, the bidirectional screw 301, the ball nut seat 302, the connecting block 303, and the second connecting rod 304... The arrangement of the slide groove 305, slider 306, second auxiliary rod 307, second damping spring 308, and rotating plate 309 allows the rotating plate 309 to be rotated when the position of the moving plate 202 needs to be adjusted. The rotating plate 309 can rotate the bidirectional screw 301, and at this time, the two ball nut seats 302 simultaneously move the moving plate 202 towards the support block 204 through the connecting block 303. This completes the adjustment of the position of the moving plate 202. When the moving plate 202 moves with the second connecting rod 304 and the second auxiliary rod 307, the slider 306 will slide in the slide groove 305. The slider 306 can assist and limit the movement of the moving plate 202, the second connecting rod 304, and the second auxiliary rod 307.

[0020] Furthermore, the bidirectional screw 301 is connected to the connecting seat 201 via a bearing, and the rotating plate 309 forms a rotating structure with the connecting seat 201 via the bidirectional screw 301. By setting the bidirectional screw 301, when it is necessary to adjust the position of the moving plate 202, the bidirectional screw 301 is rotated, and at this time the ball nut seat 302 can adjust the position of the moving plate 202.

[0021] Furthermore, the second auxiliary rod 307 is sleeved on the outer wall of the second connecting rod 304, and the slider 306 forms a sliding structure with the buffer plate 214 through the sliding groove 305. With the setting of the sliding groove 305 and the slider 306, when the moving plate 202 moves with the second connecting rod 304, the second auxiliary rod 307 can slide at one end of the buffer plate 214 under the action of the slider 306, so that the moving plate 202 and the second connecting rod 304 can move smoothly. The slider 306 can assist and limit the movement of the moving plate 202 and the second connecting rod 304.

[0022] Furthermore, the connecting block 303 is connected to one side surface of the movable plate 202. Both the ball nut seat 302 and the connecting block 303 are provided in two sets. Through the arrangement of the ball nut seat 302 and the connecting block 303, the ball nut seat 302 can move with the movable plate 202 through the connecting block 303, thereby simultaneously adjusting the position of the two movable plates 202, and adjusting the deformation of the first damping spring 210 to a certain extent.

[0023] Furthermore, a limiting block 310 is installed on one side surface of the connecting block 303, and a limiting groove 311 is opened on one side inner wall of the connecting seat 201. With the setting of the limiting block 310 and the limiting groove 311, the limiting block 310 will slide in the limiting groove 311 when the connecting block 303 moves. The limiting block 310 can limit the movement of the connecting block 303, so that the connecting block 303 can only move along the opening direction of the limiting groove 311.

[0024] Working principle: When the elastic force of the first damping spring 210 weakens, rotating the double-acting screw 301 adjusts the position of the moving plate 202, causing both moving plates 202 to move simultaneously towards the support block 204. This reduces the deformation of the first damping spring 210, thus ensuring its elastic force and extending its service life to a certain extent. When adjusting the moving plate 202 can no longer guarantee the elastic force of the first damping spring 210, it needs to be replaced. Remove the bolts and nuts between the first fixing block 208 and the second fixing block 209. The two mounting rings 207 can then separate from the connecting ring 206 and the movable plate 202, respectively. Finally, pull the movable plate 202, causing it to move away from the first auxiliary rod 205 along with the first connecting rod 203. This allows for quick disassembly of the mounting ring 207 and the first shock-absorbing spring 210, and installation is also very convenient. When adjusting the position of the movable plate 202, rotate the rotating plate 309. The rotating plate 309 can move in both directions... When the screw 301 rotates, the two ball bearing nut seats 302 simultaneously move the movable plate 202 towards the support block 204 via the connecting block 303, thus completing the adjustment of the position of the movable plate 202. As the movable plate 202 moves along with the second connecting rod 304 and the second auxiliary rod 307, the slider 306 slides in the groove 305. The slider 306 can assist and limit the movement of the movable plate 202, the second connecting rod 304, and the second auxiliary rod 307. When the connecting seat 201 is below or When the support leg 1 above the buffer plate 214 is subjected to pressure, the connecting seat 201 and the buffer plate 214 begin to move closer together. At this time, the connecting ring 206 slides on the outer wall of the first auxiliary rod 205. The connecting ring 206 will squeeze the first damping spring 210. When the first damping spring 210 is subjected to pressure, it will generate a damping and buffering rebound force. At the same time, the connecting seat 201 and the buffer plate 214 will squeeze the second damping spring 308. The second damping spring 308 will also generate a damping and buffering rebound force, which will have a damping and buffering effect on the support leg 1.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
