Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training machinery and equipment, specifically a joint encoder support structure. Background Technology

[0002] Rehabilitation training is a comprehensive treatment process in medicine that uses systematic and scientific interventions to help patients restore physical function, improve psychological state, and enhance social adaptability. A joint encoder is a sensor installed at the joint of a robot or mechanical system to measure the joint's rotation angle, position, or linear displacement, and convert mechanical motion into electrical signals to achieve precise motion control and feedback. At the same time, a joint encoder is a sensor installed at the joint of rehabilitation equipment to accurately measure the joint's rotation angle, position, or motion trajectory, and convert mechanical motion into electrical signals to provide data support for rehabilitation assessment, training control, and equipment feedback.

[0003] In existing technologies, various sophisticated mechanical devices are often used during rehabilitation training to assist patients. These devices record information that allows medical staff to monitor the patient's recovery. Typically, these devices utilize joint encoders to facilitate the rehabilitation process. However, most joint encoders are installed by connecting one side to a mounting plate using bolts or similar tools, which in turn connects to the rest of the device. While this method effectively allows for installation and use, the encoder relies solely on the connection to the mounting plate for support. This means that vibrations, external impacts, or loose connections can cause the encoder to become unstable or wobble, affecting the accuracy of the rehabilitation equipment and potentially disrupting the patient's rehabilitation process, leading to delays. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, joint encoders rely solely on the connection between themselves and the mounting plate for support and installation. This means that during use, vibrations, external collisions, or loose connections can cause the connection between the joint encoder and other equipment to become loose or wobbly, affecting the accuracy of rehabilitation training equipment. This invention proposes a joint encoder support structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a joint encoder support structure, including a mounting plate, a joint encoder body and a connecting plate are fixedly connected to one side of the mounting plate, the connecting plate is disposed on the surface of the joint encoder body, and a support mechanism is disposed on one side of the connecting plate; The support mechanism includes a fixed plate, one side of which is fixedly connected to one side of a connecting plate. A threaded rod is threadedly connected to the inner cavity of the fixed plate. A movable plate is rotatably connected to one end of the threaded rod. A first support ring block is fixedly connected to the top of the movable plate. Two bidirectional support assemblies are provided on one side of the connecting plate.

[0006] Preferably, the bidirectional support assembly includes a fixed rod, the surface of which is fixedly connected to the inner cavity of the connecting plate, a rotating block rotatably connected to the surface of the fixed rod, an inclined groove on one side of the movable plate, a connecting rod rotatably connected to the inner cavity of the rotating block, the surface of the connecting rod slidingly connected to the inner cavity of the inclined groove, an installation rod fixedly connected to the inner cavity of the rotating block, a rotating block rotatably connected to the surface of the installation rod, and a second support ring block fixedly connected to one side of the rotating block.

[0007] Preferably, a hollow arc-shaped block is fixedly connected to one side of the connecting plate. Two hollow arc-shaped blocks are provided, and a slider is fixedly connected to one side of each of the two rotating blocks. The surface of the slider is slidably connected to the inner cavity of the hollow arc-shaped block.

[0008] Preferably, a reinforcing ring block is fixedly connected to the surface of each of the two fixing rods, and one side of the reinforcing ring block is fixedly connected to one side of the connecting plate.

[0009] Preferably, a reinforcing hollow block is fixedly connected to one side of the mounting plate, and the inner cavity of the reinforcing hollow block is fixedly connected to the surface of the connecting plate.

[0010] Preferably, the inner cavities of the first support ring block and the two second support ring blocks are movably bonded with rubber layers, and the surfaces of the multiple rubber layers are provided with second hollow holes. The surfaces of the first support ring block and the two second support ring blocks are provided with first hollow holes, the size of the first hollow holes is the same as the size of the second hollow holes, and the number of the first hollow holes is the same as the number of the second hollow holes.

[0011] Preferably, a sliding plate is fixedly connected to one side of the movable plate, and the surface of the sliding plate is slidably connected to the inner cavity of the fixed plate.

[0012] The advantages of this utility model are: This invention utilizes the rotation of the threaded rod to smoothly drive the moving plate and the first support ring block to move. The movement of the moving plate allows it to push the connecting rod through the inclined groove, enabling the connecting rod and the rotating block to rotate smoothly around the center of the fixed rod. During rotation, the rotating block pushes the second support ring block, allowing the first and second support ring blocks to cooperate and support and limit the surface of the joint encoder body. This limiting and supporting of the joint encoder body surface prevents the connection between the joint encoder body and the mounting plate from loosening during use. This reduces the likelihood of decreased accuracy in rehabilitation training equipment due to loose joint encoder body. It also solves the problem that the joint encoder, which previously relied solely on its connection to the mounting plate for support and installation, is now susceptible to loosening or shaking due to vibration, external collisions, or loose connections. This not only affects the accuracy of the rehabilitation training equipment during use but also addresses the issue of the joint encoder's inability to maintain its position.

Detailed Implementation

[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 scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail. This application discloses a support structure for a joint encoder. (Refer to...) Figure 1 and Figure 4 A joint encoder support structure includes a mounting plate 1, a joint encoder body 2 and a connecting plate 3 are fixedly connected to one side of the mounting plate 1, the connecting plate 3 is disposed on the surface of the joint encoder body 2, and a support mechanism 4 is disposed on one side of the connecting plate 3. The support mechanism 4 includes a fixed plate 401, one side of which is fixedly connected to one side of the connecting plate 3. The inner cavity of the fixed plate 401 is threadedly connected to a threaded rod 402. One end of the threaded rod 402 is rotatably connected to a movable plate 403. The top of the movable plate 403 is fixedly connected to a first support ring block 404. A two-way support assembly 405 is provided on one side of the connecting plate 3. Two two-way support assemblies 405 are provided.

[0018] Mounting plate 1 is connected to the rehabilitation training equipment. Mounting plate 1 can be connected to joint encoder body 2 via bolts or other tools. Joint encoder body 2 is installed at the joint of the rehabilitation equipment, measures the joint angle or position and converts it into an electrical signal, which is fed back to the control system in real time to adjust the movement trajectory of the equipment and ensure accurate and safe training. At the same time, joint encoder body 2 is existing technology in this field, so it will not be described in detail here. Mounting plate 1 can also play a role in installing and fixing connecting plate 3, so that connecting plate 3 can be used stably. Connecting plate 3 can be connected to threaded rod 402 through fixing plate 401. Threaded rod 402 can connect to moving plate 403 and push moving plate 403 through the setting of bidirectional support component 405, so that it can move up and down. During the movement of moving plate 403, it can drive the first support ring block 404 to move together. With the cooperation of the first support ring block 404 and bidirectional support component 405, the surface of joint encoder body 2 is supported and reinforced, so that joint encoder body 2 has high stability and can be effectively supported during use.

[0019] Reference Figure 4 and Figure 6 The bidirectional support assembly 405 includes a fixed rod 4051, the surface of which is fixedly connected to the inner cavity of the connecting plate 3. A rotating block 4052 is rotatably connected to the surface of the fixed rod 4051. A sloping groove 4054 is provided on one side of the moving plate 403. A connecting rod 4053 is rotatably connected to the inner cavity of the rotating block 4052. The surface of the connecting rod 4053 is slidably connected to the inner cavity of the sloping groove 4054. An installation rod 4055 is fixedly connected to the inner cavity of the rotating block 4052. A rotating block 4056 is rotatably connected to the surface of the installation rod 4055. A second support ring block 4057 is fixedly connected to one side of the rotating block 4056. There are two bidirectional support assemblies 405, and the two bidirectional support assemblies 405 have the same structure. Therefore, the specific working principle will not be described in detail here. The connecting plate 3 can be connected to the rotating block 4052 through the fixed rod 4051, and the connecting rod 4053 connected inside the rotating block 4052 can slide smoothly inside the sloping groove 4054. Furthermore, since the rotating block 4052 is connected to the moving plate 403 through the connecting rod 4053 and the inclined groove 4054, the moving plate 403 will be limited by the rotating block 4052, and when the threaded rod 402 rotates, it can smoothly drive the moving plate 403 to move. When the moving plate 403 moves upward, it can push the connecting rod 4053 through the inclined groove 4054, and the rotating block 4052 can rotate around the center of the fixed rod 4051. The rotating block 4052 can also be connected to the rotating block 4056 through the mounting rod 4055. During the rotation process, the rotating block 4052 can smoothly drive the second support ring block 4057 to rotate and move through the rotating block 4056, so that the first support ring block 404 can cooperate with the second support ring block 4057 to realize the limitation and support of the surface of the joint encoder body 2.

[0020] Reference Figure 6 and Figure 7 A hollow arc-shaped block 7 is fixedly connected to one side of the connecting plate 3. There are two hollow arc-shaped blocks 7. A slider 8 is fixedly connected to one side of each of the two rotating blocks 4052. The surface of the slider 8 is slidably connected to the inner cavity of the hollow arc-shaped block 7. The rotating block 4052 can install and fix the slider 8. The hollow arc-shaped block 7 connected to one side of the connecting plate 3 can limit the rotation of the rotating block 4052 through its connection with the slider 8, so that the rotating block 4052 can rotate and rotate stably when it rotates around the center of the fixed rod 4051.

[0021] Reference Figure 3 Both fixed rods 4051 have a reinforcing ring block 6 fixedly connected to their surfaces. One side of the reinforcing ring block 6 is fixedly connected to one side of the connecting plate 3. The reinforcing ring block 6 can reinforce the fixed rod 4051 through its connection with the connecting plate 3, so that the fixed rod 4051 has high stability when in use. When the fixed rod 4051 connects to and limits the rotating block 4052, the fixed rod 4051 itself is not easy to shake.

[0022] Reference Figure 2 and Figure 3 A reinforcing hollow block 5 is fixedly connected to one side of the mounting plate 1. The inner cavity of the reinforcing hollow block 5 is fixedly connected to the surface of the connecting plate 3. The reinforcing hollow block 5 can strengthen and reinforce the connection between the connecting plate 3 and the mounting plate 1 by utilizing its connection with the mounting plate 1 and its connection with the surface of the connecting plate 3. This effectively strengthens and reinforces the use of the connecting plate 3, so that the connecting plate 3 has high stability when it is supported by the support mechanism 4 on the joint encoder body 2.

[0023] Reference Figure 4and Figure 5 The inner cavities of the first support ring block 404 and the two second support ring blocks 4057 are movably bonded with rubber layers 9. Second hollow holes 12 are formed on the surfaces of the multiple rubber layers 9. First hollow holes 10 are formed on the surfaces of the first support ring block 404 and the two second support ring blocks 4057. The size of the first hollow holes 10 is the same as the size of the second hollow holes 12, and the number of first hollow holes 10 is the same as the number of second hollow holes 12. The rubber layers 9 ensure that when the first support ring block 404 and the two second support ring blocks 4057 support and limit the surface of the joint encoder body 2, they are less prone to clamping and limiting forces. The excessive size of the first hollow hole 10 and the second hollow hole 12 can prevent damage to the joint encoder body 2. At the same time, they can also protect the surface of the joint encoder body 2. The number and position of the first hollow hole 10 and the second hollow hole 12 are the same, so that when the first support ring block 404 and the two second support ring blocks 4057 limit and support the joint encoder body 2, they are less likely to significantly affect the heat dissipation effect of the joint encoder body 2 during use. This reduces the situation where the heat dissipation and use of the joint encoder body 2 are significantly affected when the first support ring block 404 and the two second support ring blocks 4057 limit and support the joint encoder body 2.

[0024] Reference Figure 4 and Figure 5 A sliding plate 11 is fixedly connected to one side of the movable plate 403. The surface of the sliding plate 11 is slidably connected to the inner cavity of the fixed plate 401. The sliding plate 11 enables the movable plate 403 to move up and down by rotating the threaded rod 402, and the movement of the movable plate 403 can have high stability. It can not only move more stably, but also is not easy to shake during movement.

[0025] Working Principle: When using this device, the operator can first connect the joint encoder body 2 to the mounting plate 1 using bolts or other tools. After connecting the joint encoder body 2, the operator can rotate the threaded rod 402. When the threaded rod 402 rotates, it can smoothly drive the moving plate 403 and the first support ring block 404 to move upward. During the upward movement, the moving plate 403 can smoothly push the connecting rod 4053 through the inclined groove 4054. When the connecting rod 4053 is pushed, it can drive the rotating block 4052 to rotate around the center of the fixed rod 4051. While the rotating block 4052 is rotating, it can drive the second support ring block 4057 to rotate and move through the rotating block 4056. Thus, through the movement of the second support ring block 4057 and the first support ring block 404, and their mutual cooperation, the surface of the joint encoder body 2 is limited and supported. After that, the operator only needs to connect the mounting plate 1 to the external rehabilitation training equipment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
