Abstract
Description
Technical Field
[0001] This application relates to the field of medical rehabilitation technology, and more particularly to an angle adjustment mechanism and training equipment. Background Technology
[0002] Rehabilitation training is based on a correct and comprehensive diagnosis, and aims to promote the recovery or improvement of function by avoiding aggravating the injury or hindering its healing. Rehabilitation training is essential for most users who have completed treatment, as it not only helps them regain physical strength but also significantly promotes the function of certain joints and motor functions.
[0003] There are various types of rehabilitation training equipment, including wrist rehabilitation training equipment. Currently, wrist rehabilitation training equipment is designed to allow users with different injury conditions to train in the desired predetermined posture by adjusting the angle, thus meeting the training needs of different users.
[0004] Wrist rehabilitation training equipment generally includes a power unit, a base support component, and an electrical system. The connection between the power unit and the base support component adopts a double-hinge mechanism with damping and locking functions (hereinafter referred to as the locking mechanism). This allows the power unit to be adjusted within a certain angle range around the design center and can be locked at any angle to meet the requirements of the training scenario. The original locking mechanism was a seat-tube clamp locking structure, which had weak load-bearing capacity for rehabilitation exercises with a large range of motion. During the trial, the original mechanism's locking function showed problems such as low locking force of the hinge mechanism, changing locking angle with load changes, decreasing locking force over time, and requiring considerable force to lock, thus affecting the user experience.
[0005] Therefore, based on the shortcomings of the existing technology, the inventors have conducted numerous experiments and optimizations to develop an angle adjustment mechanism that can meet the original usage requirements, facilitate user operation, and improve structural safety and reliability. Utility Model Content
[0006] The purpose of this application is to provide an angle adjustment mechanism and training equipment, which makes it easier for users to adjust the angle of the power component to meet different training scenarios. At the same time, the angle adjustment mechanism is equipped with a damper, which can limit the power component from falling under the action of gravity when the user adjusts the angle, avoid pinching the user, and improve the structural safety and reliability.
[0007] The technical solution provided by this utility model is as follows:
[0008] An angle adjustment mechanism, comprising:
[0009] A first bracket and a second bracket are spaced apart, and a rotating component is rotatably disposed between the first bracket and the second bracket;
[0010] The first bracket is provided with a damper, and the damper has a through hole; the rotating member has a first rotating shaft on the side facing the first bracket, the first rotating shaft is slidably inserted through the through hole, and the end of the first rotating shaft facing the rotating member has a boss, and a stepped structure is formed between the boss and the first rotating shaft;
[0011] The rotating component has a second rotating shaft on the side facing the second bracket. The second rotating shaft is slidably inserted through the second bracket, and a locking component and an adjusting component are connected to the end of the second rotating shaft away from the rotating component. The locking component is used to lock the second rotating shaft so that the rotating component is maintained at a certain rotation angle. The adjusting component is used to adjust the position of the second rotating shaft relative to the second bracket so as to change the distance between the rotating component and the second bracket.
[0012] When the rotating member approaches the second bracket, the boss separates from the damper, and the locking member locks the second rotating shaft; when the rotating member moves away from the second bracket, the boss abuts against the damper, and the locking member unlocks.
[0013] In some embodiments, the adjusting member includes a screw, and the end of the second rotating shaft away from the rotating member has a threaded hole. The screw is screwed into the threaded hole from the side of the second bracket away from the rotating member. Furthermore, the end of the screw away from the second rotating shaft has a handle.
[0014] In some embodiments, the locking element includes two Allegro gears, one of which is fixed to the second rotating shaft and the other of which is fixed to the second bracket;
[0015] When the rotating component approaches the second support, the two Alleig gear discs mesh; when the rotating component moves away from the second support, the two Alleig gear discs separate.
[0016] In some embodiments, the first rotating shaft is a slit-edge rotating shaft, the slit edge is provided on the boss, and the rotating member has a mounting groove adapted to the contour of the boss. Fasteners lock the boss into the mounting groove to achieve synchronous rotation of the rotating member and the first rotating shaft; and,
[0017] The second rotating shaft is a slit rotating shaft, with the slit located at one end of the second rotating shaft facing the rotating member, and the rotating member having an assembly groove adapted to the contour of the second rotating shaft. Fasteners lock the second rotating shaft into the assembly groove to achieve synchronous rotation of the rotating member and the second rotating shaft.
[0018] In some embodiments, a limiting screw is provided on the second bracket, and a sliding groove is provided on the side wall of the second rotating shaft. The end of the limiting screw extends into the sliding groove and cooperates with the sliding groove to limit the rotation angle of the second rotating shaft and the movement distance of the second rotating shaft relative to the second bracket.
[0019] In some embodiments, an elastic element is also sleeved outside the second rotating shaft, one end of which abuts against the outer wall of the rotating member, and the other end of which abuts against the limiting screw.
[0020] This utility model also provides a training device, including:
[0021] The power unit and the angle adjustment mechanism provided in any of the above embodiments;
[0022] The rotating component is used to mount the power unit; the power unit has a power output shaft, which drives a gripper that can be held by a user, and drives the gripper to rotate relative to the rotating component.
[0023] In some embodiments, the rotating member is provided with a mounting hole; the power component includes a motor assembly, an output assembly, and a seat post clamp, the output assembly is mounted in the mounting hole, and the output assembly is provided with the power output shaft, the seat post clamp is used to connect the power output shaft and the gripper; the motor assembly is connected to the output assembly and is used to provide a power source for the output assembly.
[0024] In some embodiments, the training device further includes a base for mounting the first bracket and the second bracket to support the power component and the angle adjustment mechanism;
[0025] and / or
[0026] The power component also includes a housing covering the rotating member, the motor assembly, and the output assembly, with the power output shaft extending at least partially out of the housing to engage with the gripper.
[0027] In some embodiments, the gripping element includes a handle, and / or the gripping element includes a steering wheel.
[0028] The technical advantages of this utility model are as follows:
[0029] 1. In this application, the rotating component is rotatably connected to the first and second supports via a first and a second rotating shaft, and both the first and second rotating shafts are slidably connected. When the user needs to adjust the angle, the user moves the rotating component toward the first support via the adjusting component, the locking component unlocks, and the boss on the first rotating shaft abuts against the damper on the first support. At this time, there is no locking force on either the first or second rotating shaft; only the damper provides damping to the first rotating shaft. This reduces the risk of the power component (rotating component) falling due to gravity after unlocking, without affecting the user's angle adjustment, thus preventing injury to the user. Once the power component (rotating component) has rotated to the desired angle, the user moves the rotating component toward the second support via the adjusting component. The boss on the first rotating shaft separates from the damper, and the locking component locks the second rotating shaft, maintaining it at that angle. The operation is simple, fulfilling the original usage requirements while making it more convenient for the user, and effectively improving the overall structural safety and reliability, making it highly practical.
[0030] 2. In this application, the adjusting component includes a screw that can be screwed into a threaded hole on the second rotating shaft. By rotating the screw, the user can make the second rotating shaft slide relative to the second bracket, thereby driving the rotating component and the first rotating shaft to slide, thus realizing the angle locking and unlocking of the power component.
[0031] 3. In this application, the locking component includes two Allegri gear discs, which are respectively fixed to the second rotating shaft and the second bracket. When the user tightens the screw, the second rotating shaft moves closer to the second bracket until the two Allegri gear discs mesh, thereby locking the angle. At the same time, the boss on the first rotating shaft disengages from the damper. When the screw is loosened, the second rotating shaft moves away from the second bracket until the two Allegri gear discs disengage, and the boss on the first rotating shaft abuts against the damper. This application utilizes the structural characteristics of the Allegri gear discs and achieves the engagement and disengagement of the Allegri gear discs by driving the second rotating shaft with a screw, making the overall structure of the angle adjustment mechanism more compact. It can achieve damping and locking functions within a limited space. Moreover, the angle adjustment mechanism in this application mostly uses commonly used standard parts to achieve the damping and locking functions, which facilitates disassembly and replacement for later maintenance and reduces material costs and procurement difficulties while meeting the equipment's usage requirements.

[0047] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application can also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.
[0048] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.
[0049] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."
[0050] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.
[0051] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0052] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various components of this application are relative rather than absolute. These descriptions are appropriate when these components are in the positions shown in the drawings. If the description of the positions of these components changes, these directional indications also change accordingly.
[0053] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0054] According to a specific embodiment provided in this application, see [link to specific embodiment]. Figures 1 to 3 An angle adjustment mechanism 100 can be used in training equipment, especially rehabilitation training equipment where angle adjustment is frequently required. It can stably lock the power component 200 in the training equipment at any angle, so that users of different body types and ages can flexibly adjust the angle of the power component 200 according to their training needs, thereby meeting the requirements of different training scenarios.
[0055] For example, when the angle adjustment mechanism 100 of this application is applied to a wrist training device, the power unit 200 drives a grip 401 that can be grasped by the user. By driving the grip 401 to rotate around its own axis, the user can perform wrist rehabilitation training. Depending on the situation of different users and the needs of different training programs, the power unit 200 and the grip can be locked at a specific angle through the angle adjustment mechanism 100, thereby achieving targeted rehabilitation training and better training results.
[0056] In one example embodiment, see Figure 1 and Figures 4 to 6 The angle adjustment mechanism 100 includes a first bracket 110 and a second bracket 120 spaced apart, and a rotating member 130 rotatably disposed between the first bracket 110 and the second bracket 120. The rotating member 130 is connected to the power component 200. The tilt angle of the power component 200 can be changed by changing the angle of the rotating member 130 relative to the first bracket 110 and the second bracket 120.
[0057] The first support 110 is equipped with a damper 140, which has a through hole 141. A first rotating shaft 150 is located on the side of the rotating member 130 facing the first support 110. The first rotating shaft 150 is slidably inserted through the through hole 141, and a boss 151 is located at the end of the first rotating shaft 150 facing the rotating member 130. A stepped structure 152 is formed between the boss 151 and the first rotating shaft 150. Because the first rotating shaft 150 can slide relative to the damper 140, there is a variable gap between the end face of the boss 151 and the damper 140. When the boss 151 abuts against the damper 140, the damper 140 provides damping to the first rotating shaft 150; when the boss 151 separates from the damper 140, the damper 140 does not provide damping.
[0058] The damper 140 can be a standard part, and the first bracket 110 has an opening that is compatible with the standard part damper 140. The damper 140 is fixed in the opening by a flat-head screw.
[0059] In contrast, see Figure 6A second rotating shaft 160 is provided on the side of the rotating member 130 facing the second support 120. The second rotating shaft 160 is slidably inserted through the second support 120, and a locking member and an adjusting member are connected to the end of the second rotating shaft 160 away from the rotating member 130. The locking member is used to lock the second rotating shaft 160 so that the rotating member 130 and its fixed power component 200 can be stably maintained at a certain rotation angle for the user to perform specific rehabilitation training. The adjusting member is used to adjust the position of the second rotating shaft 160 relative to the second support 120, thereby changing the distance between the rotating member 130 and the second support 120, as well as between the boss 151 and the damper 140.
[0060] Specifically, when the rotating member 130 moves towards the second bracket 120 under the action of the adjusting member, the boss 151 separates from the damper 140, and the locking member locks the second rotating shaft 160, thus locking the angle of the second rotating shaft 160, thereby locking the rotating member 130 and the power component 200 mounted on the rotating member 130, and keeping the power component 200 stably maintained at the required tilt angle. When the rotating member 130 moves towards the first bracket 110 under the action of the adjusting member, the end face of the boss 151 abuts against the damper 140, the locking member unlocks, and does not lock the second rotating shaft 160. At this time, there is no locking force on the first rotating shaft 150 and the second rotating shaft 160. Only the damper 140 provides damping for the first rotating shaft 150. The user can adjust the rotation angle of the rotating component 130. Because the first rotating shaft 150 is damped, the rotating component 130 and the power component 200 will not fall due to gravity when unlocking, which effectively avoids the occurrence of hand pinching incidents and reduces the noise caused by the falling of the power component 200. The structure is safer and more reliable.
[0061] In one example embodiment, the locking element can be a telescopic structure, such as a rod with a spring connected to its end. In this case, the end of the spring away from the rod is fixed to the second bracket 120, and the side wall of the second rotating shaft 160 is provided with several grooves along the circumference that can cooperate with the rod. Thus, by adjusting the second rotating shaft 160, the rod can be limited or disengaged from the grooves at the corresponding angles, thereby achieving locking and unlocking of the second rotating shaft 160.
[0062] See Figure 6 Considering the limited stability and lockable angle of this structure during locking, and the difficulty in manufacturing it, in a preferred embodiment, the locking element includes two Allegri gear discs 180, one of which is fixed to the second rotating shaft 160, and the other is fixed to the second bracket 120. When the rotating member 130 approaches the second bracket 120, the two Allegri gear discs 180 engage, locking the second rotating shaft 160; when the rotating member 130 moves away from the second bracket 120, the two Allegri gear discs 180 disengage, and the locking element unlocks.
[0063] The Arri gear 180 is a standardized gear used in photographic equipment, possessing great versatility, capable of locking at multiple angles, and offering higher and more stable locking force. Moreover, by incorporating the Arri gear 180 and the stepped structure 152 of the first rotating shaft 150, this embodiment achieves the damping and locking functions of the angle adjustment mechanism 100 within a more limited space, resulting in a more compact overall structure.
[0064] In actual production, the two Allai gear discs 180 can be fixed to the second rotating shaft 160 and the second bracket 120 respectively by fasteners 403, which facilitates disassembly and replacement for later maintenance. Among them, the fasteners 403 are preferably countersunk screws, but bolts, convex screws, etc. can also be used. There are no restrictions here, and all are within the protection scope of this application.
[0065] In one specific embodiment, in order to better fix and protect the Arri gear 180 and prevent dust from entering, a gear cover 190 can also be provided on the second bracket 120. The gear cover 190 is fixed to the second bracket 120 by screws and serves as a fixed end component of the entire second bracket 120. At this time, the Arri gear 180 connected to the second bracket 120 can be fixed to the gear cover 190 by countersunk screws and connected to the second bracket 120 via the gear cover 190.
[0066] For example, the adjusting component may include a push rod, one end of which passes through the gear cover 190 and the Arri gear 180 and is connected to the second rotating shaft 160. Moving the push rod allows the second rotating shaft 160 to be moved. To facilitate user adjustment, the end of the push rod away from the second rotating shaft 160 may be provided with a handle 171 for the user to grip.
[0067] Of course, please continue to see Figure 6 In one example embodiment, the adjusting component may include a screw 170. In this case, the end of the second rotating shaft 160 away from the rotating component 130 has a threaded hole 161, and the screw 170 can be screwed into this threaded hole 161 from the side of the second bracket 120 away from the rotating component 130. Thus, the user can move the second rotating shaft 160 simply by turning the screw 170. To facilitate user adjustment, the end of the screw 170 away from the second rotating shaft 160 may have a handle 171 for the user to grip. When the user tightens the handle 171, the second rotating shaft 160 moves towards the second bracket 120; when the user loosens the handle 171, the second rotating shaft 160 moves towards the first bracket 110.
[0068] This embodiment achieves the locking function while simplifying user operation by using a more easily understood rotary locking action with a screw 170 and a handle 171. To provide a better feel for the handle 171, the design parameters were continuously adjusted and finalized through trial and error.
[0069] In the above embodiments, the screw 170 adopts a detachable assembly structure, and its length and nominal diameter can be directly replaced or adjusted as needed, making it more versatile and more conducive to the angle adjustment mechanism 100 adapting to different power components 200 and training scenarios.
[0070] Specifically, the first rotating shaft 150 is a chamfered rotating shaft, with its chamfered edge located on the boss 151. The rotating member 130 has a mounting groove 131 that matches the contour of the boss 151. The boss 151 is locked to the mounting groove 131 by fasteners 403, thereby achieving connection and synchronous rotation between the rotating member 130 and the first rotating shaft 150. Similarly, the second rotating shaft 160 is also a chamfered rotating shaft, with its chamfered edge located at the end of the second rotating shaft 160 facing the rotating member 130. The rotating member 130 has a mounting groove 131 that matches the contour of the second rotating shaft 160. The second rotating shaft 160 is locked to the mounting groove 131 by fasteners 403, thereby achieving connection and synchronous rotation between the rotating member 130 and the second rotating shaft 160.
[0071] As a preferred option, see Figure 8 and Figure 9 A limiting screw 121 is provided on the second bracket 120. This screw is preferably a common hexagonal head screw. A groove 162 is provided on the side wall of the second rotating shaft 160. The end of the limiting screw 121 extends into the groove 162 and engages with it to limit the rotation angle of the second rotating shaft 160 and the movement distance of the second rotating shaft 160 relative to the second bracket 120. Specifically, the groove 162 on both sides of the second rotating shaft 160 in the circumferential direction limits the rotation angle of the second rotating shaft 160, thereby limiting the tilt angle of the rotating component 130 and the power component 200; the groove 162 on both sides of the second rotating shaft 160 in the axial direction limits the movement distance of the second rotating shaft 160 relative to the second bracket 120.
[0072] Of course, in some embodiments, the two sides of the slide groove 162 on the axial direction of the second rotating shaft 160 may not serve as a limiting function, but only need to provide sufficient moving space for the second rotating shaft 160. This is not a limitation and is within the protection scope of this application.
[0073] Further, see Figure 6 , Figure 8 and Figure 9An elastic element 163 is also sleeved on the outside of the second rotating shaft 160. This elastic element 163 is preferably a compression spring, with one end abutting against the outer wall of the rotating member 130 and the other end abutting against the limiting screw 121. In this embodiment, by setting a compression spring, the second rotating shaft 160 can be reset, so that after the user loosens the screw 170, the second rotating shaft 160 can move directly towards the first bracket 110 under the rebound action of the compression spring, quickly completing the unlocking. At the same time, the boss 151 on the first rotating shaft 150 elastically abuts against the damper 140 to achieve the damping function.
[0074] Specifically, when the handle 171 (screw 170) is loosened, the pressure spring pushes the rotating part 130 against the first bracket 110, the end face of the boss 151 on the first rotating shaft 150 is pressed against the damper 140, the meshing surfaces of the two Arri gears 180 do not contact each other, there is no locking force on the first rotating shaft 150 and the second rotating shaft 160, only the damper 140 provides damping for the first rotating shaft 150; when the handle 171 (screw 170) is tightened, the second rotating shaft 160 is pulled towards the second bracket 120, the rotating part moves slightly towards the second bracket 120, the pressure spring is compressed, the end faces of the two Arri gears 180 mesh, the angle of the rotating part 130 and the first rotating shaft 150 and the second rotating shaft 160 is positioned, and by tightening the handle 171 (screw 170) within an appropriate torque range (usually determined by the hand of most people), the tilt angle of the power unit 200 is locked.
[0075] The angle adjustment mechanism 100 disclosed in this embodiment has a compact and simple overall structure, and is safe and reliable. It utilizes several commonly used standard parts, such as a damper 140, a pressure spring, an Alley gear 180, and a screw 170, to achieve damping and locking functions. Other individual machined parts can be processed using conventional milling and turning machines, thus reducing material costs and procurement difficulties while meeting the equipment's usage requirements. Furthermore, the angle adjustment mechanism 100 designed in this embodiment is highly versatile and widely applicable. Single-power rehabilitation medical devices with a flange-fixed power source can refer to the angle adjustment mechanism 100 in this application to achieve damping and locking functions. In addition, most of the parts in the angle adjustment mechanism 100 adopt detachable connections, which facilitates disassembly and replacement for later maintenance.
[0076] See Figures 1 to 3 and Figure 7This application also provides a training device, which may include a power component 200 and the angle adjustment mechanism 100 provided in any of the above embodiments. The rotating component 130 on the angle adjustment mechanism 100 is used to mount the power component 200, and the mounting method may be a screw-locking connection. The power component 200 has a power output shaft 221, which can drive a gripper connected to it for the user to hold, thereby rotating the gripper relative to the rotating component 130 to assist the user in rehabilitation training.
[0077] For example, see Figures 1 to 3 The gripping component may include a handle 401 for users to grip for wrist rehabilitation training. Of course, the main application scenarios for training equipment are not limited to wrist rehabilitation training, and the gripping components as accessories are not limited to handles 171-type accessories such as the handle 401. Based on feedback and other field survey data, the steering wheel 402-type accessory is also a major application accessory in rehabilitation scenarios, and previous issues with the power component 200 not locking properly mainly occurred with this accessory. The steering wheel 402-type accessory typically uses a certain angle during the adjustment of the power component 200 from horizontal to vertical as a rehabilitation training scenario to simulate a driving and control training environment. See [link to relevant documentation]. Figure 8 The gripping element may also include a steering wheel 402 for use in simulated driving training.
[0078] In actual production, the gripper may further include other accessories to meet different training scenarios. Users can flexibly replace the gripper according to the specific training scenario. This will not be elaborated on here, as all of them are within the scope of protection of this application.
[0079] Specifically, see Figure 1 , Figure 4 and Figure 5 The power component 200 includes a motor assembly 210, an output assembly 220, and a seat clamp 230. The output assembly 220 has a power output shaft 221, and the seat clamp 230 is used to connect the power output shaft 221 and the gripper. The motor assembly 210 is connected to the output assembly 220 and provides power to the output assembly 220. The rotating component 130 has a mounting hole 132, and the output assembly 220 is locked and fixed in the mounting hole 132 with screws, thereby fixing the power component 200 to the rotating component 130.
