Description

Technical Field

[0001] This utility model relates to the field of rehabilitation robots, specifically to a shockproof air pump base. Background Technology

[0002] Rehabilitation robots are generally used for the rehabilitation of stroke patients after they are out of danger. They primarily guide patients in hand and foot exercises to gradually restore nerve, joint, and muscle function. Among the many existing rehabilitation robots, pneumatic soft rehabilitation robots are gaining increasing attention due to their lightweight advantages. The air pump is a crucial component of pneumatic soft robots, mainly supplying compressed gas to the drive unit, causing the drive unit to bend or straighten, thus synchronizing the patient's body movements. However, the air pump vibrates during operation, generating noise that is detrimental to the patient's rehabilitation.

[0003] Therefore, there is a need in the field for an air pump structure that can effectively reduce and prevent vibration. Summary of the Invention

[0004] The purpose of this utility model is to overcome the defects of the existing technology and provide a shockproof air pump base.

[0005] To achieve the purpose of this utility model, this application provides the following technical solution.

[0006] In a first aspect, this application provides a shock-absorbing air pump mount for mounting an air pump on the main frame of a pneumatic soft robot. The air pump mount includes a first pump mount, wherein the first pump mount is fixed to the air pump, and a horizontal shock-absorbing structure and a vertical shock-absorbing structure are provided between the first pump mount and the main frame. In this application, the air pump is fixed to the first pump mount with screws. This connection can be considered a rigid link, and there will be no vibration between them. Therefore, by reducing the vibration between the first pump mount and the main frame, noise can be effectively reduced. This application provides a multi-level shock-absorbing structure in the horizontal and vertical directions between the first pump mount and the main frame to minimize collisions between the first pump mount and the main frame.

[0007] In one embodiment of the first aspect, the first pump base includes a horizontal mounting plate, a connecting plate integrally disposed at both ends of the mounting plate and arranged vertically downward, and a shock-absorbing plate integrally disposed at the bottom of the connecting plate and arranged horizontally. At least one pair of connecting lugs are also installed at each end of the mounting plate. The connecting lugs are arranged vertically downward, and each pair of connecting lugs is located on both sides of the connecting plate. The air pump is fixedly installed above the mounting plate. The horizontal shock-absorbing structure is connected between the connecting plate and the main frame, and the vertical shock-absorbing structure is disposed between the shock-absorbing plate and the main frame.

[0008] In one embodiment of the first aspect, the top of the main frame is U-shaped or frame-shaped, including a base plate and vertical plates disposed at opposite ends of the base plate and arranged vertically upwards. The first pump seat is located inside the main frame, and the horizontal damping structure is connected between the vertical plate and the connecting lug. The vertical damping structure is disposed between the base plate and the damping plate.

[0009] In this application, the connecting clip can take many forms, such as designing the connecting clip in an inverted T shape, or opening two connecting holes on the connecting clip. The main purpose is to allow the pull ring at one end of the tension spring to quickly hook onto the connecting clip, thereby achieving quick installation of the tension spring, and the structure is simple.

[0010] In one embodiment of the first aspect, the horizontal damping structure includes multiple tension springs, each with a loop at both ends. The loops are respectively connected to a hook and a connecting lug on a vertical plate. This tension spring structure allows the first pump seat to float above the main frame to a certain extent, minimizing hard collisions between the first pump seat and the main frame, thereby reducing the possibility of noise generation. Of course, in this application, to ensure the levitation effect of the first pump seat, the tension springs used need to have a certain stiffness; that is, the horizontally arranged tension springs must be able to support the weight of the first pump seat in the vertical direction.

[0011] In one embodiment of the first aspect, circular holes are formed at corresponding positions of the base plate and the damping plate, and the vertical damping structure is disposed in the circular holes of the base plate and the damping plate.

[0012] In one embodiment of the first aspect, the vertical damping structure includes snap-fit ​​portions at both ends and a damping portion in the middle, with a connecting portion between the snap-fit ​​portions and the damping portion. The diameter of the connecting portion is less than or equal to the diameter of the circular hole, and the length of the connecting portion is the same as the thickness of the base plate and the damping plate. The diameters of the snap-fit ​​portions and the connection points between the damping portion and the connecting portion are both greater than the diameter of the circular hole. This structure can effectively hold the vertical damping structure between the base plate and the damping plate, fully forming a buffer pad structure to reduce hard impacts.

[0013] In one embodiment of the first aspect, the vertical damping structure is made of silicone or rubber. However, whether it is silicone or rubber, it needs to have a certain degree of hardness because the component is arranged vertically and needs to bear a certain weight. If it does not have a certain degree of hardness, the first pump seat and the main frame will not be stable in the vertical direction.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This application sets up multiple shock-absorbing structures between the first pump base and the main frame, that is, adopts multi-stage shock absorption, which can cut off the collision between the air pump and the main frame as much as possible, reduce vibration, and reduce noise.
