Description

Technical Field

[0001] The present application relates to the technical field of testing equipment, and in particular to a flexion testing device and a flexion testing method for an orthopedic brace. Background Art

[0002] In the relevant technical field, flexure testing equipment is mainly used to evaluate and test the flexure performance of various materials under repeated bending or torsion conditions. For example, in the medical industry, the flexure testing of orthopedic braces cannot be separated from specially designed flexure testing equipment. These devices can simulate the stress and strain that the material is subjected to during actual use, thereby ensuring the reliability and durability of the material and orthopedic brace in long-term use.

[0003] However, existing flexion test equipment has certain limitations in terms of test range and flexibility. They can usually only test specific types of orthopedic braces and cannot cover a variety of orthopedic braces of different shapes and sizes. This means that in order to meet diverse testing needs, testing organizations or manufacturers have to purchase multiple flexion test equipment of different specifications. This not only increases the purchase cost of the equipment, but also increases the complexity of maintenance and operation. Summary of the invention

[0004] The embodiments of the present application provide a flexion test device and a flexion test method for an orthopedic brace, which can perform flexion tests on orthopedic braces more conveniently and quickly, and have wider adaptability, and can perform flexion tests on various types of orthopedic braces.

[0005] In a first aspect, an embodiment of the present application provides a flexion test device for an orthopedic brace, wherein the flexion test device for an orthopedic brace includes a drive assembly and at least one gripping assembly.

[0006] The driving assembly is used to provide driving force; at least one grasping assembly is connected to the driving assembly, the grasping assembly includes a clamping portion, a transmission mechanism and an offset mechanism, the clamping portion and one end of the transmission mechanism are connected through the offset mechanism, the other end of the transmission mechanism is connected to the driving assembly, the transmission mechanism can drive the clamping portion to reciprocate along a preset trajectory, one end of the offset mechanism is connected to the clamping portion, the other end of the offset mechanism is connected to the transmission mechanism, and the offset mechanism is used to fine-tune the direction or position of the clamping portion;

[0007] The clamping portion can clamp and lock the preset position of the orthopedic brace, the orthopedic brace is fixedly connected to the preset area or another clamping portion, and the clamping portion can repeatedly bend or twist the orthopedic brace during movement.

[0008] The above structure can make the installation of the orthopedic brace more flexible, and then the flexion test device of the orthopedic brace can be adapted to multiple types of orthopedic braces at the same time, thereby improving the test range of the flexion test device of the orthopedic brace and increasing the adaptability of the flexion test device of the orthopedic brace. The above structure can perform the flexion test of the orthopedic brace more conveniently and quickly, and has a wider adaptability, and can perform flexion tests on multiple types of orthopedic braces.

[0009] The main function of the drive assembly is to provide the necessary driving force to ensure the smooth progress of the entire test process. At least one gripping assembly is connected to the drive assembly to ensure the coordinated work between the two. The gripping assembly itself consists of a clamping part and a transmission mechanism, wherein the clamping part is connected to one end of the transmission mechanism, and the other end of the transmission mechanism is connected to the drive assembly. This design enables the transmission mechanism to effectively drive the clamping part to reciprocate along a pre-set trajectory.

[0010] The function of the clamping portion is to firmly clamp and lock the preset position of the orthopedic brace to ensure that the orthopedic brace remains stable during the test. The orthopedic brace can be fixedly connected to the preset area, or connected to another clamping portion. When the orthopedic brace is fixedly connected to the preset area, the preset area usually refers to different positions on the support frame, and these positions can be adjusted according to different models of orthopedic braces. In addition, the orthopedic brace can also be fixedly connected to another clamping portion, so that the flexion test device of the orthopedic brace will be equipped with at least two gripping components, so that multiple orthopedics can be tested at the same time.

[0011] This structural design makes the installation process of the orthopedic brace more flexible and changeable, thereby enabling the flexion test device of the orthopedic brace to adapt to a variety of different types of orthopedic braces. This flexibility significantly improves the test range of the flexion test device of the orthopedic brace, allowing it to cover more types of orthopedic braces. At the same time, this design also greatly increases the adaptability of the flexion test device of the orthopedic brace, enabling it to better meet the needs of different users, thereby showing higher practicality and efficiency in practical applications.

[0012] In some examples, two gripping components are provided, namely a first gripping component and a second gripping component.

[0013] The first grabbing assembly is connected to the driving assembly, and the first grabbing assembly includes a first clamping portion, a first transmission mechanism, and a first offset mechanism. The first clamping portion and one end of the first transmission mechanism are connected through the first offset mechanism, and the other end of the first transmission mechanism is connected to the driving assembly. The first transmission mechanism can drive the first clamping portion to reciprocate along a first trajectory.

[0014] The second grabbing assembly is connected to the driving assembly, and the second grabbing assembly includes a second clamping portion, a second transmission mechanism, and a second offset mechanism. The second clamping portion and one end of the second transmission mechanism are connected through the first offset mechanism, and the other end of the second transmission mechanism is connected to the driving assembly. The second transmission mechanism can drive the second clamping portion to reciprocate along a second trajectory.

[0015] The first clamping portion and the second clamping portion move independently of each other, or the first clamping portion and the second clamping portion move jointly with each other;

[0016] The first clamping portion can clamp and lock the orthopedic brace at a first position, the second clamping portion can clamp and lock the orthopedic brace at a second position, and the first clamping portion and the second clamping portion can repeatedly bend or twist the orthopedic brace during movement;

[0017] Wherein, at least part of the transmission parts in the first transmission mechanism and the second transmission mechanism are telescopic parts, and the telescopic parts are locked at the length or position after telescoping.

[0018] The first gripping assembly is capable of performing a specific task by being connected to the driving assembly. Specifically, the first gripping assembly includes a first clamping portion and a first transmission mechanism. One end of the two portions are connected to each other, and the other end of the first transmission mechanism is connected to the driving assembly. This structural design enables the first transmission mechanism to effectively drive the first gripping portion to reciprocate along a predetermined first trajectory.

[0019] Similarly, the second grabbing assembly is also connected to the driving assembly. It includes a second clamping part and a second transmission mechanism. One end of these two parts is also connected together, and the other end of the second transmission mechanism is connected to the driving assembly. This design enables the second transmission mechanism to drive the second clamping part to reciprocate along a predetermined second trajectory.

[0020] It is worth noting that the first clamping portion and the second clamping portion can move independently or in conjunction. The flexibility of this design enables the first clamping portion to clamp and lock the orthopedic brace in a first position, while the second clamping portion can clamp and lock the orthopedic brace in a second position. During the movement, the first clamping portion and the second clamping portion can repeatedly bend or twist the orthopedic brace.

[0021] Through the cooperation of the first clamping portion and the second clamping portion, the installation flexibility of the orthopedic brace can be significantly improved. This flexibility enables the flexion test device of the orthopedic brace to be adapted to a variety of different types of orthopedic braces, thereby greatly expanding the test range of the flexion test device of the orthopedic brace. In addition, this design also increases the adaptability of the flexion test device of the orthopedic brace, so that it can be more widely used in various different testing requirements.

[0022] In some examples, the first transmission mechanism includes a first transmission rod and a first connecting rod, one end of the first transmission rod is connected to the driving assembly, the other end of the first transmission rod is connected to the first connecting rod, and the end of the first connecting rod away from the first transmission rod is connected to the first clamping portion through the first offset mechanism;

[0023] The second transmission mechanism includes a second transmission rod and a second connecting rod, one end of the second transmission rod is connected to the driving assembly, the other end of the second transmission rod is connected to the second connecting rod, and the end of the second connecting rod away from the second transmission rod is connected to the second clamping part through the second offset mechanism.

[0024] The first transmission mechanism may be composed of a first transmission rod and a first connecting rod. Specifically, one end of the first transmission rod is connected to the drive assembly, and the other end of the first transmission rod is connected to the first connecting rod. The end of the first connecting rod, that is, the end away from the first transmission rod, is connected to the first clamping portion. Similarly, the second transmission mechanism is composed of a second transmission rod and a second connecting rod. One end of the second transmission rod is also connected to the drive assembly, and the other end of the second transmission rod is connected to the second connecting rod. The end of the second connecting rod, that is, the end away from the second transmission rod, is connected to the second clamping portion. Through this design, the first clamping portion and the second clamping portion can cooperate with each other, making the installation process of the orthopedic brace more flexible and convenient. In this way, the flexion test device of the orthopedic brace can adapt to a variety of different types of orthopedic braces, thereby significantly improving the test range of the flexion test device of the orthopedic brace. In addition, this design also increases the adaptability of the flexion test device of the orthopedic brace, so that it can better meet different test requirements and improve the versatility and practicality of the equipment.

[0025] Based on the above embodiment, at least one of the first transmission rod and the first connecting rod can be set as a telescopic member, and the telescopic length of the first transmission rod or the first connecting rod can be adjusted and locked as needed. The lengths of the first transmission rod and the first connecting rod can be adjusted and locked accordingly as needed, and the new activity trajectory generated by the first clamping portion can be predicted through precise conditions to facilitate subsequent flexion tests. At least one of the corresponding second transmission rod and the second connecting rod can also be set as a telescopic member, similar to the setting method of the first transmission rod and the first connecting rod, which will not be repeated here.

[0026] In some examples, the driving assembly includes a first rocker adapted to the driving member and the first transmission mechanism, one end of the first rocker is fixedly connected to the driving member, and the first transmission mechanism includes a first transmission rod, a first push rod, a first push rod, and a first connecting rod;

[0027] One end of the first transmission rod is movably connected to the other end of the first rocker, the other end of the first transmission rod is movably connected to one end of the first push rod, the other end of the first push rod is movably connected to one end of the first push rod, the other end of the first push rod is fixedly connected to one end of the first connecting rod, and the other end of the first connecting rod is movably connected to the first clamping portion;

[0028] The driving assembly also includes a second rocker matched with the second transmission mechanism, one end of the second rocker is fixedly connected to the driving member, and the second transmission mechanism includes a second transmission rod, a second push rod, a second push rod and a second connecting rod;

[0029] One end of the second transmission rod is movably connected to the other end of the second rocker, the other end of the second transmission rod is movably connected to one end of the second push rod, the other end of the second push rod is movably connected to one end of the second push rod, the other end of the second push rod is fixedly connected to one end of the second connecting rod, and the other end of the second connecting rod is movably connected to the second clamping part.

[0030] The driving assembly includes a driving member and a first rocker arm matched therewith. One end of the first rocker arm is connected to the driving member by a fixed connection, ensuring stable transmission of force between the two. The first transmission mechanism is composed of multiple parts, including a first transmission rod, a first push rod, a first push rod and a first connecting rod. These parts cooperate with each other by a movable connection or a fixed connection to form a complete transmission chain.

[0031] Specifically, one end of the first transmission rod is connected to the other end of the first rocker arm by a movable connection, so that the first transmission rod can swing within a certain range. The other end of the first transmission rod is connected to one end of the first push rod by a movable connection, allowing the first push rod to swing within a certain angle. The other end of the first push rod is connected to one end of the first push rod by a movable connection, so that the first push rod can move within a certain range. The other end of the first push rod is connected to one end of the first connecting rod by a fixed connection, ensuring stable transmission of force between the two. Finally, the other end of the first connecting rod is connected to the first clamping part by a movable connection, so that the first clamping part can move within a certain range, thereby realizing flexible clamping of the orthopedic brace.

[0032] In addition, the driving assembly also includes a second rocker adapted to the second transmission mechanism. One end of the second rocker is connected to the driving member by a fixed connection, ensuring stable transmission of force between the two. The second transmission mechanism is also composed of multiple parts, including a second transmission rod, a second push rod, a second push rod and a second connecting rod. These parts cooperate with each other by a movable connection or a fixed connection to form a complete transmission chain.

[0033] Specifically, one end of the second transmission rod is connected to the other end of the second rocker by a movable connection, so that the second transmission rod can swing within a certain range. The other end of the second transmission rod is connected to one end of the second push rod by a movable connection, allowing the second push rod to swing within a certain angle. The other end of the second push rod is connected to one end of the second push rod by a movable connection, so that the second push rod can move within a certain range. The other end of the second push rod is connected to one end of the second connecting rod by a fixed connection, ensuring stable transmission of force between the two. Finally, the other end of the second connecting rod is connected to the second clamping part by a movable connection, so that the second clamping part can move within a certain range, thereby realizing flexible clamping of the orthopedic brace.

[0034] Through the cooperation of the first clamping part and the second clamping part, the installation of the orthopedic brace can be made more flexible, so that the flexion test device of the orthopedic brace can be adapted to multiple types of orthopedic braces at the same time. This design not only improves the test range of the flexion test device of the orthopedic brace, but also increases the adaptability of the flexion test device of the orthopedic brace, so that it can better meet different test requirements.

[0035] Based on the above-mentioned embodiment, at least one of the first rocker, the first transmission rod, the first top rod, the first push rod and the first connecting rod can be set as a telescopic member, and the telescopic length of each of the first rocker, the first transmission rod, the first top rod, the first push rod and the first connecting rod can be adjusted and locked as needed. The lengths of the first rocker, the first transmission rod, the first top rod, the first push rod and the first connecting rod can be adjusted and locked one by one as needed, and the new activity trajectory generated by the first clamping part can be obtained through precise conditions. Predictable activity trajectory can be obtained to facilitate subsequent flexion tests. At least one of the corresponding second rocker, the second transmission rod, the second top rod, the second push rod and the second connecting rod can also be set as a telescopic member, which is similar to the setting method of the first rocker, the first transmission rod, the first top rod, the first push rod and the first connecting rod, and will not be repeated here.

[0036] In some examples, the orthopedic brace includes at least one of a waist auxiliary support brace, a joint auxiliary support brace, a leg auxiliary support brace, and a neck auxiliary support brace. Different types of braces can be selected for testing as needed.

[0037] In some examples, the first clamping portion is hinged to the first connecting rod, and the second clamping portion is hinged to the second connecting rod.

[0038] The first clamping part and the first connecting rod can be connected together by a hinged connection, and similarly, the second clamping part and the second connecting rod can be connected together by a hinged connection. This hinged connection can take many forms, one of which is a chain hinge, which is similar to our common hinge structure and has higher stability in a specific direction; the other is a ball hinge, which has better adaptability and can adapt to more movement directions. This application takes a chain hinge as an example for illustrative description.

[0039] In some examples, the first clamping portion includes a first fixing plate and a first locking plate, the first fixing plate and the first locking plate are lockably connected via a fixing member, and the first fixing plate and the first locking plate can cooperate to clamp and lock the first position of the orthopedic brace;

[0040] The second clamping portion includes a second fixing plate and a second locking plate, the second fixing plate and the second locking plate are lockably connected via a fixing member, and the second fixing plate and the second locking plate can cooperate to clamp and lock the second position of the orthopedic brace.

[0041] The first clamping portion is composed of a first fixing plate and a first locking plate. Specifically, the first fixing plate and the first locking plate are tightly and lockably connected together through a series of fixing members. This structure enables the first fixing plate and the first locking plate to work together to effectively clamp and lock the orthopedic brace in a predetermined first position. In this way, the orthopedic brace can be firmly fixed to ensure accuracy and stability during the measurement process.

[0042] Similarly, the second clamping portion is composed of a second fixing plate and a second locking plate. The second fixing plate and the second locking plate are also lockably connected together through a series of fixings, so that the second fixing plate and the second locking plate can cooperate with each other to clamp and lock the orthopedic brace in a predetermined second position. This design ensures the accurate clamping and locking of the orthopedic brace at different positions, further improving the reliability and flexibility of the entire measurement system.

[0043] In some examples, when there are at least two gripping assemblies, the driving assembly includes a driving motor and a converter, the driving motor is connected to the converter, and the converter can convert the output end of the driving motor into at least two output sub-ends, each of which is connected to a gripping assembly;

[0044] Alternatively, the drive assembly includes at least two drive motors, each drive motor being connected to a gripping assembly.

[0045] The number of the grabbing components is set to at least two. In this case, the driving component includes a driving motor and a converter. The driving motor is connected to the converter, and the converter is used to convert the output end of the driving motor into at least two output sub-ends. Each output sub-end is respectively connected to a grabbing component, thereby realizing the driving of multiple grabbing components.

[0046] In addition, there is another possible configuration in which the drive assembly includes at least two independent drive motors, each of which is directly connected to a gripping assembly, so as to achieve a separate drive for each gripping assembly. Such a design can ensure that each gripping assembly can be operated independently, improving the flexibility and efficiency of the system.

[0047] In some examples, the drive assembly further includes a transmission disposed between the drive motor and the gripping assembly.

[0048] The drive assembly not only includes a drive motor, but is further equipped with a transmission. The transmission is designed and installed between the drive motor and the gripping assembly to form a complete transmission system. By introducing the transmission, the control of the drive assembly becomes more diverse and sophisticated. This design makes the testing method of the orthopedic brace more flexible and can be adjusted accordingly according to different testing requirements. Therefore, this improvement significantly improves the test range of the flexion test device for orthopedic braces, enabling it to cover more types of orthopedic braces. At the same time, this also increases the adaptability of the flexion test device for orthopedic braces, enabling it to better adapt to various different testing environments and conditions, thereby improving the overall test efficiency and accuracy.

[0049] In some examples, the flexion testing device for an orthopedic brace further includes a support frame, and the drive assembly and the gripping assembly are both disposed on the support frame;

[0050] At least one auxiliary fixing structure is arranged on the support frame. When the volume of the orthopedic brace is larger than a preset size, the auxiliary fixing structure clamps and locks a part of the position of the orthopedic brace.

[0051] The support frame is equipped with a drive assembly and a gripper assembly. These assemblies are carefully arranged in appropriate positions on the support frame to ensure the stability of the device and the convenience of operation. The design of the support frame is not only to carry these assemblies, but also to take into account the overall structural strength and stability.

[0052] In order to accommodate orthopedic braces of different sizes, at least one auxiliary fixing structure is specially designed on the support frame. When the volume of the orthopedic brace exceeds the preset size, these auxiliary fixing structures can effectively clamp and lock the partial position of the orthopedic brace. This design ensures that the orthopedic brace can be kept in the proper position during the flexion test, thereby ensuring the accuracy and reliability of the test results.

[0053] In a second aspect, an embodiment of the present application provides a method for testing the flexion of an orthopedic brace, using the flexion testing device for an orthopedic brace as described above to perform a flexion test on the orthopedic brace.

[0054] The flexion test method of the orthopedic brace uses the above-mentioned flexion test device of the orthopedic brace to perform the flexion test of the orthopedic brace. The specific test methods include:

[0055] First, fix the orthopedic brace to be tested on the clamping part to ensure its stability and accuracy. Then, the drive assembly starts working, and the transmission mechanism drives the clamping part to reciprocate along the preset trajectory. In this process, the clamping part will repeatedly bend or twist the orthopedic brace to simulate the stress conditions in actual use. During the test, the deformation and fatigue level of the orthopedic brace can be monitored in real time to evaluate its performance and durability. In this way, the reliability and safety of the orthopedic brace in actual use can be effectively tested to ensure that it meets the relevant standards and requirements.

DETAILED DESCRIPTION

[0063] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0064] To solve the above technical problems, please refer to Figure 1-Figure 4 As shown, the first aspect of the present application proposes a flexion test device for an orthopedic brace, which can perform flexion tests on orthopedic braces more conveniently and quickly, and has wider adaptability, and can perform flexion tests on various types of orthopedic braces.

[0065] Reference Figure 1-Figure 4 As shown, in some examples, the flexion testing device for an orthopedic brace includes a drive assembly 100 and at least one gripping assembly.

[0066] The driving assembly 100 is used to provide driving force; at least one grasping assembly is connected to the driving assembly 100, and the grasping assembly includes a clamping portion, a transmission mechanism and an offset mechanism. The clamping portion and one end of the transmission mechanism are connected through the offset mechanism, and the other end of the transmission mechanism is connected to the driving assembly 100. The transmission mechanism can drive the clamping portion to reciprocate along a preset trajectory. One end of the offset mechanism is connected to the clamping portion, and the other end of the offset mechanism is connected to the transmission mechanism. The offset mechanism is used to fine-tune the direction or position of the clamping portion;

[0067] The clamping portion can clamp and lock the preset position of the orthopedic brace, and the orthopedic brace is fixedly connected to the preset area or another clamping portion, and the clamping portion can repeatedly bend or twist the orthopedic brace during movement. The above-mentioned preset position can be any position of the orthopedic brace, usually the edge position of the part that needs to be tested for flexion. When the orthopedic brace is fixedly connected to the preset area, the preset area can correspond to different positions on the support frame 400, and different positions can correspond to different models of orthopedic braces. Alternatively, the orthopedic brace can be fixedly connected to another clamping portion, and the flexion test device of the orthopedic brace will have at least two gripping components at the same time.

[0068] The above structure can make the installation of the orthopedic brace more flexible, and then the flexion test device of the orthopedic brace can be adapted to multiple types of orthopedic braces at the same time, thereby improving the test range of the flexion test device of the orthopedic brace and increasing the adaptability of the flexion test device of the orthopedic brace. The above structure can perform the flexion test of the orthopedic brace more conveniently and quickly, and has a wider adaptability, and can perform flexion tests on multiple types of orthopedic braces.

[0069] The main function of the drive assembly 100 is to provide the necessary driving force to ensure the smooth progress of the entire test process. At least one gripping assembly is connected to the drive assembly 100 to ensure the coordinated work between the two. The gripping assembly itself consists of a clamping part and a transmission mechanism, wherein the clamping part and one end of the transmission mechanism are connected, and the other end of the transmission mechanism is connected to the drive assembly 100. Such a design enables the transmission mechanism to effectively drive the clamping part to reciprocate along a preset trajectory.

[0070] The function of the clamping portion is to firmly clamp and lock the preset position of the orthopedic brace to ensure that the orthopedic brace remains stable during the test. The orthopedic brace can be fixedly connected to the preset area, or connected to another clamping portion. When the orthopedic brace is fixedly connected to the preset area, the preset area generally refers to different positions on the support frame 400, and these positions can be adjusted according to different models of orthopedic braces. In addition, the orthopedic brace can also be fixedly connected to another clamping portion, so that the flexion test device of the orthopedic brace will be equipped with at least two gripping components, so that multiple orthopedic braces can be tested at the same time.

[0071] This structural design makes the installation process of the orthopedic brace more flexible and changeable, thereby enabling the flexion test device of the orthopedic brace to adapt to a variety of different types of orthopedic braces. This flexibility significantly improves the test range of the flexion test device of the orthopedic brace, allowing it to cover more types of orthopedic braces. At the same time, this design also greatly increases the adaptability of the flexion test device of the orthopedic brace, enabling it to better meet the needs of different users, thereby showing higher practicality and efficiency in practical applications.

[0072] In addition, the offset mechanism is also crucial in the gripping assembly. One end of the offset mechanism is connected to the clamping part, and the other end is connected to the transmission mechanism. The main function of the offset mechanism is to fine-tune the orientation or position of the clamping part to ensure that the clamping part can accurately grasp and fix the orthotic brace while maintaining its stability and accuracy during the test. Through this fine-tuning, the accuracy and reliability of the test results can be ensured, thereby providing strong data support for the design and improvement of the orthotic brace. And more complex flexion tests can be performed through the offset mechanism as needed.

[0073] The flexion testing device for the orthopedic brace of the present application can effectively simulate various flexion conditions in actual use through the coordinated work of the driving assembly 100 and at least one grasping assembly, thereby comprehensively evaluating the performance of the orthopedic brace.

[0074] When performing a flexion test on an orthopedic brace, the brace needs to be subjected to a series of bending and stretching actions to ensure its durability and reliability in actual use. In order to complete this test process, the drive assembly 100 plays a vital role, which is responsible for providing the necessary driving force to ensure that the entire test process can proceed smoothly. The drive assembly 100 is connected to at least one gripping assembly to achieve the coordinated work between the two, thereby ensuring the efficiency and accuracy of the test.

[0075] The gripping assembly is composed of a clamping portion and a transmission mechanism, and the two parts are connected by one end, and the other end of the transmission mechanism is connected to the drive assembly 100. This design enables the transmission mechanism to effectively drive the clamping portion to reciprocate along a preset trajectory. The function of the clamping portion is to firmly clamp and lock the preset position of the orthopedic brace to ensure that the brace remains stable during the test. In order to adapt to different types of orthopedic braces, the clamping portion can be fixedly connected to different positions on the support frame 400, and these positions can be adjusted as needed. In addition, the orthopedic brace can also be fixedly connected to another clamping portion, so that the flexion test device of the orthopedic brace will be equipped with at least two gripping assemblies, so that multiple orthopedic braces can be tested at the same time.

[0076] This structural design makes the installation process of the orthopedic brace more flexible and changeable, thereby enabling the flexion test device of the orthopedic brace to adapt to a variety of different types of orthopedic braces. This flexibility significantly improves the test range of the flexion test device of the orthopedic brace, allowing it to cover more types of orthopedic braces. At the same time, this design also greatly increases the adaptability of the flexion test device of the orthopedic brace, enabling it to better meet the needs of different users, thereby showing higher practicality and efficiency in practical applications.

[0077] In addition, the offset mechanism also plays a vital role in the gripping assembly. One end of the offset mechanism is connected to the clamping part, and the other end is connected to the transmission mechanism. The main function of the offset mechanism is to fine-tune the orientation or position of the clamping part to ensure that the clamping part can accurately grasp and fix the orthotic brace while maintaining its stability and accuracy during the test. Through this fine-tuning, the accuracy and reliability of the test results can be ensured, thereby providing strong data support for the design and improvement of orthotic braces.

[0078] The flexion testing device for an orthopedic brace described in the present application can effectively simulate various flexion conditions in actual use through the coordinated work of the driving assembly 100 and at least one gripping assembly, thereby comprehensively evaluating the performance of the orthopedic brace.

[0079] In terms of the design of a tool for testing the flexion performance of an orthopedic brace, the present invention specifically relates to applications in the field of orthopedics, and can solve the aging and fracture problems encountered by technicians when testing orthopedic braces. The present invention emphasizes the method and device for preparing an orthopedic brace, as well as the comfort and convenience of use. However, the prior art does not clearly indicate whether the brace can be used for a long time and how to judge its usage time. At present, there are a variety of materials on the market for making orthopedic braces, but unfortunately, there is no tool that can test the usage time of the orthopedic brace, so that after a period of use, the brace has problems such as cracks and fractures, which brings unnecessary trouble to the patient. For the maker of the orthopedic brace, it is possible to more effectively evaluate the performance of the brace so as to develop better quality materials to adapt to the wearing time required by the patient. Therefore, there is an urgent need for a flexion tool to solve the above-mentioned safety hazard problem. The present invention designs a tool for testing the flexion of an orthopedic brace, which can effectively reflect the wearing cycle of the brace.

[0080] The present invention provides an orthopedic tool test fixture for testing the fatigue aging performance of an orthopedic brace. The test fixture comprises a motor, an axis arm, a speed regulating device, a sensor counting display, a clamp and a limit controller. The orthopedic tool test fixture comprises a transverse structural part, a longitudinal structural part and a connecting part connected in sequence along a first direction, and the sensor counting display is located between the limit controllers.

[0081] In some examples, the power of the motor (driving member) is not less than 250W, and the number of the connecting shaft arms (transmission rod and connecting rod) is not less than 5. Figure 1 and Figure 2, taking five-axis arms as an example, the length of the first three-axis arm is not limited to greater than or equal to 10cm, the length of the second four-axis arm is not limited to greater than or equal to 30cm, and the length of the fifth axis arm is not limited to greater than or equal to 20cm. The clamp is not limited to whether it can rotate freely. The limit controller is not limited to the opening and closing distance, and the opening and closing distance is greater than the maximum circumference of the brace. The opening and closing distance is controlled by the length of the second four-axis arm. The speed adjustment device is not limited to referring to the customer's wearing time, and can be adjusted at will. The present invention is not limited to testing the fatigue aging performance of orthopedic braces, but can also test any device that needs to open and close. In addition, it is not limited to adding a heating box next to the clamp to test the flexion performance of the orthopedic brace under high temperature conditions. Similarly, it is not limited to adding a liquid nitrogen cooling box next to the clamp to test the flexion performance of the orthopedic brace under low temperature conditions.

[0082] As an orthopedic brace flexion test fixture, it can reflect the aging resistance of the brace in a relatively short time. For example, a brace made of a certain material cracked after being worn for one and a half years. The patient put it on and took it off six times a day on average, a total of 3,285 times in one and a half years. However, using the orthopedic brace flexion test fixture, it only takes 164 minutes to conduct an opening and closing test every three seconds on average. This can not only easily predict the use time of the material, but also provide patients with reliable technical data. This not only saves the research and development time of technicians, but also provides necessary technical support for material developers.

[0083] The key technology of the present invention is to simulate the opening and closing mode of the orthopedic brace and use a new tool to test the flexural performance of the material so as to accurately understand the aging resistance fracture time of the brace.

[0084] In some examples, the orthopedic brace includes at least one of a lumbar auxiliary support brace, a joint auxiliary support brace, a leg auxiliary support brace, and a neck auxiliary support brace.

[0085] In some specific examples, the orthopedic braces mentioned may include a variety of different types, such as lumbar auxiliary support braces, joint auxiliary support braces, leg auxiliary support braces, and neck auxiliary support braces. The main function of these orthopedic braces is to provide additional support and stability for the corresponding parts of the human body, help relieve pain, correct posture, or prevent further injuries. By using these orthopedic braces, patients can better carry out daily activities and improve their quality of life.

[0086] Specifically, some types of orthopedic braces are listed here, and the orthopedic braces of the present application are not limited to the above-mentioned ones. Orthopedic braces are devices used to help and support a certain part of the human body to improve or correct body posture or function. These braces can be auxiliary support devices for the waist, joints, legs or neck, including at least one of the above parts. They are generally used for medical rehabilitation or prevention and treatment of pain and dysfunction caused by various reasons.

[0087] An orthosis is a medical aid used to assist and support specific parts of the body to improve posture or function.

[0088] Lumbar support brace: A device specifically designed to support and stabilize the lower back, help relieve lower back pain or support an injured lower back.

[0089] Joint support braces: provide additional support and stability to the joints and are often used during the rehabilitation process of joint pain or injury.

[0090] Leg auxiliary support brace: used to support and stabilize the legs, help walking or standing, suitable for patients with leg injuries or functional disorders.

[0091] Neck support brace: used to support and stabilize the neck, often used to relieve neck pain or in rehabilitation after neck injury.

[0092] Reference Figure 1-Figure 4 As shown, in some examples, two gripping assemblies are provided, namely a first gripping assembly 200 and a first gripping assembly 200 .

[0093] The first grabbing assembly 200 is connected to the driving assembly 100. The first grabbing assembly 200 includes a first clamping portion 210, a first transmission mechanism, and a first offset mechanism 260. The first clamping portion 210 and one end of the first transmission mechanism are connected through the first offset mechanism 260. The other end of the first transmission mechanism is connected to the driving assembly 100. The first transmission mechanism can drive the first clamping portion 210 to reciprocate along a first trajectory.

[0094] The second grabbing assembly 300 is connected to the driving assembly 100, and the second grabbing assembly 300 includes a second clamping portion 310, a second transmission mechanism, and a second offset mechanism 360. One end of the second clamping portion 310 and the second transmission mechanism are connected through the second offset mechanism 360, and the other end of the second transmission mechanism is connected to the driving assembly 100. The second transmission mechanism can drive the second clamping portion 310 to reciprocate along the second trajectory.

[0095] The first clamping portion 210 and the second clamping portion 310 move independently of each other, or the first clamping portion 210 and the second clamping portion 310 move jointly with each other;

[0096] The first clamping portion 210 can clamp and lock the first position of the orthopedic brace, and the second clamping portion 310 can clamp and lock the second position of the orthopedic brace. The first clamping portion 210 and the second clamping portion 310 can repeatedly bend or twist the orthopedic brace during movement;

[0097] Wherein, at least part of the transmission parts in the first transmission mechanism and the second transmission mechanism are telescopic parts, and the telescopic parts are locked at the length or position after telescoping.

[0098] The first offset mechanism 260 and the second offset mechanism 360 can fine-tune the orientation or position of the corresponding clamping portion to ensure that the clamping portion can accurately grasp and fix the orthopedic brace while maintaining its stability and accuracy during the test. Through such fine-tuning, the accuracy and reliability of the test results can be ensured, thereby providing strong data support for the design and improvement of the orthopedic brace.

[0099] The first deflection mechanism 260 or the second deflection mechanism 360 may be a hinge mechanism (see Figure 3 ), rack and pinion mechanism (refer to Figure 4 ), at least one of a screw-nut mechanism, a worm gear mechanism, and a gear mechanism. Figure 4 After the first offset mechanism 260 or the second offset mechanism 360 adopts a gear rack mechanism, the first offset mechanism 260 can be correspondingly provided with a first micro motor 261 for electric control, which can be coordinated with a certain controller and control program to achieve intelligent control, and the second offset mechanism 360 can be correspondingly provided with a second micro motor 361 for electric control, which can be coordinated with a certain controller and control program to achieve intelligent control.

[0100] In these gripping assemblies, at least some of the transmission parts in the first transmission mechanism and the second transmission mechanism are designed as telescopic parts. These telescopic parts can be locked in the length or position after extension, so that the clamping parts with different activity trajectories can be adjusted as needed. The activity trajectory of the first clamping part 210 and the activity trajectory of the second clamping part 310 can be adjusted separately or simultaneously to meet different operating requirements. This design enables the gripping assembly to flexibly cope with various complex operating scenarios and improve work efficiency and precision.

[0101] Of course, the activity trajectory can also be adjusted by using corresponding transmission parts of different lengths as needed, and the specific settings can be made according to needs.

[0102] The first grabbing assembly 200 is capable of performing a specific task by being connected to the driving assembly 100. Specifically, the first grabbing assembly 200 includes a first clamping portion 210 and a first transmission mechanism. One end of the two portions are connected to each other, and the other end of the first transmission mechanism is connected to the driving assembly 100. This structural design enables the first transmission mechanism to effectively drive the first clamping portion 210 to reciprocate along a predetermined first trajectory.

[0103] Similarly, the second grabbing assembly 300 is also connected to the driving assembly 100. It includes a second clamping portion 310 and a second transmission mechanism. One end of the two parts are also connected together, and the other end of the second transmission mechanism is connected to the driving assembly 100. This design enables the second transmission mechanism to drive the second clamping portion 310 to reciprocate along a predetermined second trajectory.

[0104] It is worth noting that the first clamping portion 210 and the second clamping portion 310 can move independently or in conjunction. The flexibility of this design enables the first clamping portion 210 to clamp and lock the first position of the orthopedic brace, while the second clamping portion 310 can clamp and lock the second position of the orthopedic brace. During the movement, the first clamping portion 210 and the second clamping portion 310 can repeatedly bend or twist the orthopedic brace.

[0105] The cooperation between the first clamping portion 210 and the second clamping portion 310 can significantly improve the installation flexibility of the orthopedic brace. This flexibility enables the flexion test device of the orthopedic brace to be adapted to a variety of different types of orthopedic braces, thereby greatly expanding the test range of the flexion test device of the orthopedic brace. In addition, this design also increases the adaptability of the flexion test device of the orthopedic brace, so that it can be more widely used in various different testing requirements.

[0106] In some examples, the first transmission mechanism includes a first transmission rod 220 and a first connecting rod 250, one end of the first transmission rod 220 is connected to the driving assembly 100, the other end of the first transmission rod 220 is connected to the first connecting rod 250, and the end of the first connecting rod 250 away from the first transmission rod 220 is connected to the first clamping portion 210 through a first offset mechanism 260;

[0107] The second transmission mechanism includes a second transmission rod 320 and a second connecting rod 350, one end of the second transmission rod 320 is connected to the driving assembly 100, the other end of the second transmission rod 320 is connected to the second connecting rod 350, and the end of the second connecting rod 350 away from the second transmission rod 320 is connected to the second clamping portion 310 via a second offset mechanism 360.

[0108] The first transmission mechanism may be composed of a first transmission rod 220 and a first connecting rod 250. Specifically, one end of the first transmission rod 220 is connected to the driving assembly 100, and the other end of the first transmission rod 220 is connected to the first connecting rod 250. The end of the first connecting rod 250, that is, the end away from the first transmission rod 220, is connected to the first clamping portion 210. Similarly, the second transmission mechanism is composed of a second transmission rod 320 and a second connecting rod 350. One end of the second transmission rod 320 is also connected to the driving assembly 100, and the other end of the second transmission rod 320 is connected to the second connecting rod 350. The end of the second connecting rod 350, that is, the end away from the second transmission rod 320, is connected to the second clamping portion 310. Through this design, the first clamping portion 210 and the second clamping portion 310 can cooperate with each other, making the installation process of the orthopedic brace more flexible and convenient. In this way, the flexion test device for orthopedic braces can adapt to a variety of different types of orthopedic braces, thereby significantly improving the test range of the flexion test device for orthopedic braces. In addition, this design also increases the adaptability of the flexion test device for orthopedic braces, so that it can better meet different test requirements and improve the versatility and practicality of the device.

[0113] The driving assembly 100 includes a driving member and a first rocker 130 adapted thereto. One end of the first rocker 130 is connected to the driving member by a fixed connection, ensuring stable transmission of force between the two. The first transmission mechanism is composed of multiple parts, including a first transmission rod 220, a first push rod 230, a first push rod 240 and a first connecting rod 250. These parts cooperate with each other by a movable connection or a fixed connection to form a complete transmission chain.

[0114] Specifically, one end of the first transmission rod 220 is connected to the other end of the first rocker 130 by a movable connection, so that the first transmission rod 220 can swing within a certain range. The other end of the first transmission rod 220 is connected to one end of the first push rod 230 by a movable connection, allowing the first push rod 230 to swing within a certain angle. The other end of the first push rod 230 is connected to one end of the first push rod 240 by a movable connection, so that the first push rod 240 can move within a certain range. The other end of the first push rod 240 is connected to one end of the first connecting rod 250 by a fixed connection, ensuring a stable transmission force between the two. Finally, the other end of the first connecting rod 250 is connected to the first clamping portion 210 by a movable connection, so that the first clamping portion 210 can move within a certain range, thereby realizing flexible clamping of the orthopedic brace.

[0115] In addition, the driving assembly 100 also includes a second rocker 140 adapted to the second transmission mechanism. One end of the second rocker 140 is connected to the driving member by a fixed connection, ensuring stable transmission of force between the two. The second transmission mechanism is also composed of multiple parts, including a second transmission rod 320, a second push rod 330, a second push rod 340 and a second connecting rod 350. These parts cooperate with each other by a movable connection or a fixed connection to form a complete transmission chain.

[0116] Specifically, one end of the second transmission rod 320 is connected to the other end of the second rocker 140 by a movable connection, so that the second transmission rod 320 can swing within a certain range. The other end of the second transmission rod 320 is connected to one end of the second push rod 330 by a movable connection, allowing the second push rod 330 to swing within a certain angle. The other end of the second push rod 330 is connected to one end of the second push rod 340 by a movable connection, so that the second push rod 340 can move within a certain range. The other end of the second push rod 340 is connected to one end of the second connecting rod 350 by a fixed connection, ensuring a stable transmission force between the two. Finally, the other end of the second connecting rod 350 is connected to the second clamping portion 310 by a movable connection, so that the second clamping portion 310 can move within a certain range, thereby realizing flexible clamping of the orthopedic brace.

[0117] Through the cooperation of the first clamping portion 210 and the second clamping portion 310, the installation of the orthopedic brace can be made more flexible, so that the flexion test device of the orthopedic brace can be adapted to multiple types of orthopedic braces at the same time. This design not only improves the test range of the flexion test device of the orthopedic brace, but also increases the adaptability of the flexion test device of the orthopedic brace, so that it can better meet different test requirements.

[0118] In order to further improve the transmission stability in each of the above transmission mechanisms, a guide rail assembly 500 can be connected to the first push rod 230. The guide rail assembly 500 includes a guide rail structure 510 and a slider 520. The slider 520 can slide on the guide rail and has only one degree of freedom. The slider 520 is fixedly connected to the outer peripheral side of the first push rod 230. In the process of the first push rod 230 pushing the first push rod 240, the slider 520 can limit the push rod to ensure the stability and accuracy of its motion trajectory.

[0119] Similarly, a guide assembly 600 may also be provided on the first push rod 240. The guide assembly 600 has a guide seat that can be mounted on the support frame 400, and a guide hole is provided on the guide seat. The first push rod 240 is always slidably connected to the guide hole, and through the cooperation between the first push rod 240 and the guide hole, the moving track of the first clamping part 210 can be made more stable and controllable, thereby improving the accuracy of the test.

[0120] The same can also be applied to the second push rod 330 and the second push rod 340. A guide rail assembly 500 can be connected to the second push rod 330, and the guide rail assembly 500 includes a guide rail structure 510 and a slider 520. The slider 520 can slide on the guide rail and has only one degree of freedom. The slider 520 is fixedly connected to the outer peripheral side of the second push rod 330. In the process of the second push rod 330 pushing the second push rod 340, the slider 520 can limit the push rod to ensure the stability and accuracy of its motion trajectory.

[0121] At the same time, a guide assembly 600 may also be provided on the second push rod 340. The guide assembly 600 has a guide seat that can be mounted on the support frame 400, and a guide hole is provided on the guide seat. The second push rod 340 is always slidably connected to the guide hole. Through the cooperation between the second push rod 340 and the guide hole, the activity track of the second clamping part 310 can be made more stable and controllable, thereby improving the accuracy of the test.

[0122] Among them, the first transmission rod 220 is set at an angle to the first rocker arm 130, the first transmission rod 220 is set at an angle to the first push rod 230, the first push rod 230 is set at an angle to the first push rod 240, the first push rod 240 is set at an angle to the first connecting rod 250, the second transmission rod 320 is set at an angle to the second rocker arm 140, the second transmission rod 320 is set at an angle to the second push rod 330, the second push rod 330 is set at an angle to the second push rod 340, and the second push rod 340 is set at an angle to the second connecting rod 350.

[0123] A weight-reducing hole is disposed in the middle of the first connecting rod 250 , and / or a weight-reducing hole is disposed in the middle of the second connecting rod 350 .

[0124] The weight-reducing holes can reduce the weight of the first connecting rod 250 or the second connecting rod 350 , and can increase the elasticity and toughness of the corresponding connecting rod, thereby reducing the risk of fracture during the flexure test and increasing the service life.

[0125] The design of the flexion test device of the above-mentioned orthopedic brace includes the precise angle settings of multiple key components to ensure the stability and reliability of the device. Specifically, the first transmission rod 220 and the first rocker 130 in the device are set at a specific angle to ensure smoother force transmission. Similarly, the first transmission rod 220 and the first push rod 230 are also set at an angle so that the first push rod 230 can effectively transmit force to the first push rod 240. The first push rod 240 and the first connecting rod 250 are also set at an angle to ensure further transmission and dispersion of force. The same angle setting also exists between the second transmission rod 320 and the second rocker 140, the second transmission rod 320 and the second push rod 330, and the second push rod 330 and the second push rod 340. Finally, the angle setting of the second push rod 340 and the second connecting rod 350 completes the construction of the entire force transmission chain.

[0126] In addition, the other end of the first connecting rod 250 is connected to the first clamping portion 210 by a movable connection, and the other end of the second connecting rod 350 is connected to the second clamping portion 310 by a movable connection. This design makes the installation process of the orthopedic brace more flexible and can be adjusted accordingly according to different types of orthopedic braces. In this way, the flexion test device of the orthopedic brace can be adapted to a variety of different types of orthopedic braces, thereby significantly improving its test range and increasing the adaptability of the device, so that it can meet more diverse testing needs.

[0127] In order to further optimize the performance of the device, a weight-reducing hole is specially provided in the middle of the first connecting rod 250. Such a design can effectively reduce the weight of the first connecting rod 250, thereby reducing the total mass of the entire device and improving its convenience of operation. At the same time, the existence of the weight-reducing hole can also increase the elasticity and toughness of the first connecting rod 250, so that it can better withstand repeated stress during the flexure test, reduce the risk of fracture, and thus extend the service life of the device. The same design is also applied to the middle of the second connecting rod 350. By providing a weight-reducing hole, the second connecting rod 350 can also achieve similar performance improvement.

[0128] In some examples, the first clamping portion 210 is hinged to the first connecting rod 250 , and the second clamping portion 310 is hinged to the second connecting rod 350 .

[0129] The first clamping portion 210 and the first connecting rod 250 can be connected together by a hinged connection. Similarly, the second clamping portion 310 and the second connecting rod 350 can be connected together by a hinged connection. There are many forms of this hinged connection, one of which is a chain hinge, which is similar to our common hinge structure and has higher stability in a specific direction; the other is a ball hinge, which has better adaptability and can adapt to more movement directions. This application takes the chain hinge as an example for illustrative description.

[0130] In some examples, the first clamping portion 210 includes a first fixing plate 211 and a first locking plate 212, the first fixing plate 211 and the first locking plate 212 are lockably connected via a fixing member, and the first fixing plate 211 and the first locking plate 212 can cooperate to clamp and lock the first position of the orthopedic brace;

[0131] The second clamping portion 310 includes a second fixing plate 311 and a second locking plate 312 . The second fixing plate 311 and the second locking plate 312 are lockably connected via a fixing member. The second fixing plate 311 and the second locking plate 312 can cooperate to clamp and lock the second position of the orthopedic brace.

[0132] The first clamping portion 210 is composed of a first fixing plate 211 and a first locking plate 212. Specifically, the first fixing plate 211 and the first locking plate 212 are tightly and lockably connected together through a series of fixings. This structure enables the first fixing plate 211 and the first locking plate 212 to work together to effectively clamp and lock the orthopedic brace in a predetermined first position. In this way, the orthopedic brace can be firmly fixed to ensure accuracy and stability during the measurement process.

[0133] Similarly, the second clamping portion 310 is composed of a second fixing plate 311 and a second locking plate 312. The second fixing plate 311 and the second locking plate 312 are also lockably connected together through a series of fixing members, so that the second fixing plate 311 and the second locking plate 312 can cooperate with each other to clamp and lock the orthopedic brace in a predetermined second position. This design ensures the accurate clamping and locking of the orthopedic brace at different positions, further improving the reliability and flexibility of the entire measurement system.

[0134] In some examples, when there are at least two gripping assemblies, the driving assembly 100 includes a driving motor 110 and a converter 120, the driving motor 110 is connected to the converter 120, and the converter 120 can convert the output end of the driving motor 110 into at least two output sub-ends, each of which is connected to a gripping assembly;

[0135] Alternatively, the driving assembly 100 includes at least two driving motors 110 , and each driving motor 110 is connected to a gripping assembly.

[0136] The number of the gripping components is set to at least two. In this case, the driving component 100 includes a driving motor 110 and a converter 120. The driving motor 110 is connected to the converter 120, and the function of the converter 120 is to convert the output end of the driving motor 110 into at least two output sub-ends. Each output sub-end is respectively connected to a gripping component, thereby realizing the driving of multiple gripping components.

[0137] In addition, there is another possible configuration in which the drive assembly 100 includes at least two independent drive motors 110, each of which is directly connected to a gripping assembly, so as to achieve a separate drive for each gripping assembly. Such a design can ensure that each gripping assembly can be operated independently, thereby improving the flexibility and efficiency of the system.

[0138] In some examples, the drive assembly 100 further includes a transmission, which is disposed between the drive motor 110 and the gripping assembly. This can make the control of the drive assembly 100 more diversified, make the testing method of the orthopedic brace more flexible, increase the testing range of the flexion testing device for the orthopedic brace, and increase the adaptability of the flexion testing device for the orthopedic brace.

[0139] The drive assembly 100 not only includes a drive motor 110, but is further equipped with a transmission. The transmission is designed and installed between the drive motor 110 and the gripping assembly to form a complete transmission system. By introducing the transmission, the control of the drive assembly 100 becomes more diverse and sophisticated. This design makes the testing method of the orthopedic brace more flexible and can be adjusted accordingly according to different testing requirements. Therefore, this improvement significantly improves the test range of the flexion test device of the orthopedic brace, so that it can cover more types of orthopedic braces. At the same time, this also increases the adaptability of the flexion test device of the orthopedic brace, so that it can better adapt to various different testing environments and conditions, thereby improving the overall test efficiency and accuracy.

[0140] In some examples, the flexion testing device for orthopedic braces further includes a support frame 400, and the drive assembly 100 and the gripping assembly are both disposed on the support frame 400;

[0141] At least one auxiliary fixing structure 410 is disposed on the support frame 400. When the volume of the orthopedic brace is larger than a preset size, the auxiliary fixing structure 410 clamps and locks a part of the position of the orthopedic brace.

[0142] The bottom of the support frame 400 may be provided with a locking ear plate 420, and the support frame 400 may be stably fixed at a corresponding position through the locking ear plate 420, such as being fixed on a larger bracket, or fixed on the ground or wall with an expansion wire.

[0143] Auxiliary moving parts such as universal wheels can also be provided at the bottom of the support frame 400 as needed to facilitate the transfer of the support frame 400. Auxiliary moving parts such as universal wheels can be selected or selected with the locking ear plate 420; if necessary, auxiliary moving parts such as universal wheels can coexist with the locking ear plate 420.

[0144] The driving assembly 100 and the grabbing assembly are mounted on the support frame 400. These assemblies are carefully arranged at appropriate positions of the support frame 400 to ensure the stability of the device and the convenience of operation. The design of the support frame 400 is not only to carry these assemblies, but also takes into account the overall structural strength and stability.

[0145] In order to accommodate orthopedic braces of different sizes, at least one auxiliary fixing structure 410 is specially designed on the support frame 400. When the volume of the orthopedic brace exceeds the preset size, these auxiliary fixing structures 410 can effectively clamp and lock the partial position of the orthopedic brace. This design ensures that the orthopedic brace can be kept in the proper position during the flexion test, thereby ensuring the accuracy and reliability of the test results.

[0146] In addition, in order to further enhance the stability and flexibility of the support frame 400, a locking lug 420 may be provided at the bottom thereof. These locking lugs 420 may conveniently fix the support frame 400 in an appropriate position, such as fixing it to a larger bracket, or fixing it to the ground or wall using expansion wires. This design makes the support frame 400 more stable during use, and also facilitates quick adjustment and positioning in different test environments.

[0147] In order to further improve the mobility and flexibility of the support frame 400, auxiliary moving parts such as universal wheels can be set at the bottom of the support frame 400 according to actual needs. These universal wheels allow the support frame 400 to be easily transferred between different test sites, greatly improving the portability and ease of operation of the device. Universal wheels and other auxiliary moving parts can be selected with the locking ear plate 420 to meet different usage requirements. In some cases, in order to take into account stability and mobility, universal wheels and other auxiliary moving parts can also coexist with the locking ear plate 420, so that while ensuring the stability of the support frame 400, it can also be easily moved and adjusted.

[0148] In a second aspect, an embodiment of the present application provides a method for testing the flexion of an orthopedic brace, using the flexion testing device for an orthopedic brace as described above to perform a flexion test on the orthopedic brace.

[0149] The flexion test device of the orthopedic brace includes a driving assembly 100 and at least one grabbing assembly. The main function of the driving assembly 100 is to provide the necessary driving force to ensure the smooth progress of the entire testing process. As for the at least one grabbing assembly, it is closely connected to the driving assembly 100 to ensure the coordinated work between the two. Each grabbing assembly includes a clamping part and a transmission mechanism. One end of the clamping part and the transmission mechanism are connected, and the other end of the transmission mechanism is connected to the driving assembly 100. Such a design enables the transmission mechanism to effectively drive the clamping part to reciprocate along a preset trajectory.

[0150] The main function of the clamping portion is to clamp and lock the preset position of the orthopedic brace. The orthopedic brace can be any component that needs to be tested for flexion, which is fixedly connected to the preset area or another clamping portion. During the test, the clamping portion can repeatedly bend or twist the orthopedic brace. The preset position generally refers to the edge position of the key part of the orthopedic brace that needs to be tested for flexion. When the orthopedic brace is fixedly connected to the preset area, the preset area can correspond to different positions on the support frame 400, and these different positions can correspond to different models of orthopedic braces to meet the testing requirements of different specifications. In addition, the orthopedic brace can also be fixedly connected to another clamping portion, so that the flexion test device of the orthopedic brace will have at least two gripping components at the same time, so that multiple components can be tested at the same time, thereby improving the testing efficiency.

[0151] The flexion test method of the orthopedic brace uses the above-mentioned flexion test device of the orthopedic brace to perform the flexion test of the orthopedic brace. The specific test methods include:

[0152] First, the orthopedic brace to be tested is fixed on the clamping part to ensure its stability and accuracy. Then, the drive assembly 100 starts working, and the transmission mechanism drives the clamping part to reciprocate along a preset trajectory. In this process, the clamping part will repeatedly bend or twist the orthopedic brace to simulate the stress conditions in actual use. During the test, the deformation and fatigue level of the orthopedic brace can be monitored in real time to evaluate its performance and durability. In this way, the reliability and safety of the orthopedic brace in actual use can be effectively detected to ensure that it meets the relevant standards and requirements.

[0153] The wheel of the present application may be a non-pneumatic tire, specifically a top load-bearing tire, and the flexion test device of the orthopedic brace in the present application may perform a flexion test on the wheel spokes.

[0154] The tire force-bearing mode can be set to two bottom load-bearing modes and a top load-bearing mode. Traditional pneumatic tires and solid tires are both bottom load-bearing modes, that is, the load is transferred to the ground through the sidewall or the bottom elastomer; the tire force-bearing principle of the top load-bearing mode is that the tire tread has a support ring, the spokes are flexible, and the flexible spokes are circumferentially distributed in the support ring. The load is suspended on the support ring through the flexible spokes distributed on the top, and the flexible spokes at the bottom only play a role of easy bending and deformation, and do not play a major supporting force role.

[0155] Specifically, the non-pneumatic tire in the present application is a top-loaded tire with a rigid outer ring. During driving, the load of the tire is mainly borne by the rigid outer ring. The non-pneumatic tire also includes spokes, which include spokes with traction capabilities, referred to as traction units. When the tire is under pressure, the traction unit at the relatively upper side will be stretched and generate tensile force, and the traction unit at the relatively lower side will be compressed. Since the spokes themselves do not have supporting force, the force on the wheel hub will be transmitted to the upper side of the outer ring through the upper traction unit, and the rigid characteristics of the outer ring will then transmit the force to the position below the outer ring in contact with the ground.

[0156] The same or similar numbers in the drawings of this embodiment correspond to the same or similar parts; in the description of this application, it should be understood that if the terms "upper", "lower", "left", "right", etc. indicate an orientation or position relationship based on the orientation or position relationship shown in the drawings, it is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
