[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.
[0026] Please refer to the following Figure 1 A seat test module and a test device according to an embodiment of the present utility model are described.
[0027] like Figure 1 As shown, the seat test module according to the embodiment of the utility model includes: a prosthetic buttocks, a calf 4 and a driving assembly 5. The prosthetic buttocks is suitable for connecting to a mechanical arm. The driving assembly 5 is arranged on the prosthetic buttocks. One end of the calf 4 is connected to the driving assembly 5, and the other end of the calf 4 extends in a direction away from the prosthetic buttocks. The driving assembly 5 is used to drive the calf 4 to rotate to adjust the angle between the calf 4 and the prosthetic buttocks so that the calf 4 can be maintained at any angle.
[0028] It should be noted that the calf 4 can extend downwards away from the artificial buttocks, or can extend forwards away from the artificial buttocks. Alternatively, the calf 4 can extend obliquely downwards and forwards away from the artificial buttocks.
[0029] It can be understood that the up-down, left-right, front-back directions of the artificial buttocks are consistent with the up-down, left-right, front-back directions of the seat.
[0030] According to the seat test module of the embodiment of the utility model, when conducting a test simulating a human body entering and exiting a seat, the mechanical arm can drive the artificial buttocks to move between a position that fits the seat cushion and a position that is away from the seat cushion, thereby performing a fatigue test on the seat cushion, and since the artificial buttocks are connected to the calf 4 through the driving assembly 5, when the mechanical arm drives the artificial buttocks to move, the calf 4 can be synchronously driven to move between a position that fits the leg support and a position that is away from the leg support, so as to perform a fatigue test on the leg support. The driving assembly 5 can drive the calf 4 to rotate, and since the driving assembly 5 can adjust the angle between the calf 4 and the artificial buttocks so that the calf 4 is kept at any angle, the scene of the user actually using the leg support can be simulated. In other words, the driving assembly 5 can change the force applied by the calf 4 to the calf leg support. Therefore, the seat test module of the embodiment of the utility model can test the seat cushion and the leg support of the seat at the same time, and has a wide range of applications, and can realize the verification of simulating real scenes of entering and exiting the seat.
[0031] It should be noted that the seat test module can simulate the sitting posture of a real human body, that is, the fake buttocks are used to simulate the posture of the buttocks and part of the thigh in a sitting state, and the calf 4 is used to simulate the calf in a sitting state.
[0032] In some embodiments, the prosthetic buttocks includes a prosthetic buttocks body 1, a connecting plate 2 and an adapter 3, wherein the connecting plate 2 is disposed on the upper side of the prosthetic buttocks body 1, the adapter 3 and the drive assembly 5 are both mounted on the connecting plate 2, and the adapter 3 is suitable for connection to a robotic arm.
[0033] It is understandable that the adapter 3 and the drive assembly 5 are both mounted on the connecting plate 2, so as to facilitate the assembly of the seat test module and have a compact structure. For example, the adapter 3 is mounted on the connecting plate 2 by a threaded member, and the drive assembly 5 is mounted on the connecting plate 2 by a threaded member.
[0034] Specifically, the driving assembly 5 includes a driving motor 51 and a reducer 52. The driving motor 51 is arranged on the connecting plate 2 and adjacent to the front end of the artificial buttocks. The reducer 52 is arranged at the front end of the driving motor 51 and is connected to the driving motor 51 in a transmission manner. The output shaft 521 of the reducer 52 generally extends along the left-right direction of the artificial buttocks and is connected to the calf 4 in a transmission manner. It should be noted that the extension direction of the output shaft 521 can be consistent with the left-right direction of the artificial buttocks. Of course, the extension direction of the output shaft 521 can also have a certain angle with the left-right direction of the artificial buttocks to simulate the scene in which the two calves of the human body are separated by a certain angle in a real environment.
[0035] In the embodiment of the present utility model, since the reducer 52 can reduce the speed of the driving motor 51 to match the moving speed of the artificial leg model, the accuracy of the test can be improved.
[0036] On the other hand, the reducer 52 is arranged at the front end of the driving motor 51 and is in driving connection with the driving motor 51. The output shaft 521 of the reducer 52 extends along the left and right direction of the artificial hip and is in driving connection with the calf 4, thereby simulating the knee part of the human body. The seat test module of the embodiment of the utility model can make the seat test module more anthropomorphic by setting the driving component 5 as the above structure, and make the test accuracy of the seat test module more accurate.
[0037] For example, a motor seat 53 is provided at the front end of the connecting plate 2, and the motor seat 53 is detachably connected to the connecting plate 2, and the driving motor 51 is detachably connected to the motor seat 53, thereby making it convenient for the staff to assemble and disassemble the seat test module.
[0038] Optionally, the calf 4 includes a calf body 41 and a bracket 42, the calf body 41 is connected to the bracket 42, the bracket 42 has two ear seats 421 arranged at intervals, the reducer 52 also includes a reduction housing 522, both ends of the output shaft 521 extend out of the reduction housing 522, and both ends of the output shaft 521 are respectively connected to the two ear seats 421 in a one-to-one correspondence. It can be understood that part of the reduction housing 522 is arranged between the two ear seats 421, and the output shaft 521 of the reducer 52 generally passes through the reduction housing 522 in the left-right direction and is connected to the ear seats 421, thereby improving the stability of the connection between the reducer 52 and the calf 4, which is conducive to extending the service life of the seat test module.
[0039] In some embodiments, the position of the connecting plate 2 along the front-to-back direction of the artificial hip body 1 is adjustable, thereby enabling the front-to-back movement of the calf 4 so that the seat test module can test leg rests of different positions and types.
[0040] Optionally, the artificial hip further includes a slide rail (not shown) and a slider (not shown), the slide rail is provided on one of the connecting plate 2 and the artificial hip body 1, the slider is provided on the other of the connecting plate 2 and the artificial hip body 1, and the position of the slider relative to the slide rail along the front-to-back direction of the artificial hip body 1 is adjustable, thereby realizing the front-to-back adjustment of the connecting plate 2. The seat test module of the embodiment of the utility model can make the processing and manufacturing of the seat test module simple, convenient to assemble, and low in cost by adjusting the connecting plate 2 front-to-back in the above manner.
[0041] In some embodiments, the adapter 3 is disposed on the upper side of the connecting plate 2, and the bottom of the adapter 3 has a first connecting surface (not shown), which is in contact with the connecting plate 2, and the top of the adapter 3 has a second connecting surface 31, which is suitable for connecting with the mechanical arm, and the second connecting surface 31 gradually extends upward in the direction from front to back of the artificial buttocks. It can be understood that the front-to-back direction of the artificial buttocks is consistent with the front-to-back direction of the seat. Among them, the front-to-back direction of the artificial buttocks is the front-to-back direction of the seat.
[0042] like Figure 1 As shown, the adapter 3 is generally triangular, the bottom surface of the adapter 3 is the first connecting surface, the upper end surface of the adapter 3 is the second connecting surface 31, and the second connecting surface 31 gradually extends upward in the direction from front to back of the artificial buttocks, thereby facilitating the connection between the moving end of the robotic arm and the artificial buttocks, and facilitating the application of downward and backward pressure toward the artificial buttocks.
[0043] Optionally, the angle between the first connecting surface and the second connecting surface 31 is greater than or equal to 10° and less than or equal to 30°. For example, the angle between the first connecting surface and the second connecting surface 31 can be 10°, 15°, 18°, 25°, 28° and 30°. The inventors of the present application have found through experimental research that when the angle between the first connecting surface and the second connecting surface 31 is designed with the above parameters, it is convenient to apply downward and backward pressure to the artificial buttocks, and the test effect is good.
[0044] Optionally, the upper side of the artificial buttocks body 1 has an installation cavity 11, and the connecting plate 2, the adapter 3 and at least part of the driving assembly 5 are arranged in the installation cavity 11, thereby reducing the space occupied by the seat test module, making its overall structural design compact and the production cost low.
[0045] In some embodiments, there are two drive assemblies 5, which are arranged at intervals along the left and right directions of the artificial hip, and there are two calves 4, which are respectively connected to the two drive assemblies 5. It can be understood that the two calves 4 are respectively controlled by the two drive assemblies 5, thereby making the seat test module more anthropomorphic, and further ensuring the accuracy of the experimental data.
[0046] A testing device according to another embodiment of the present invention comprises a mechanical arm and a seat testing module according to the present invention, wherein the mechanical arm is connected to an adapter 3 .
[0047] The test equipment of the embodiment of the utility model can drive the artificial buttocks to move between the position of fitting the seat cushion and the position away from the seat cushion through the mechanical arm when conducting a test simulating a human body entering and exiting the seat, thereby performing a fatigue test on the seat cushion, and because the artificial buttocks are connected to the calf 4 through the driving assembly 5, when the mechanical arm drives the artificial buttocks to move, the calf 4 can be synchronously driven to move between the position of fitting the leg support and the position away from the leg support, so as to perform a fatigue test on the leg support. The driving assembly 5 can drive the calf 4 to rotate, and because the driving assembly 5 can adjust the angle between the calf 4 and the artificial buttocks so that the calf 4 is kept at any angle, the scene of the user actually using the leg support can be simulated. In other words, the driving assembly 5 can change the force applied by the calf 4 to the calf leg support. Therefore, the seat test module of the test equipment of the embodiment of the utility model can test the seat cushion and the leg support of the seat at the same time, and has a wide range of applications.
