Prosthetic hip for in-and-out testing

Abstract

The artificial buttocks for moving in and out tests proposed by the present invention include an artificial back mechanism, an artificial buttocks mechanism, a back-buttocks connection mechanism, and a robot connection mechanism. The bottom of the artificial back mechanism is rotatably connected to the back-buttocks connection mechanism, the tail of the artificial buttocks mechanism is detachably connected to the back-buttocks connection mechanism, and the robot connection mechanism is fixedly connected to the back-buttocks connection mechanism and is connected to the artificial back mechanism through a telescopic mechanism. The artificial buttocks for moving in and out tests proposed by the present invention adopts a split structural design, which not only separates the back module from the buttocks module, but also further separates the buttocks module into a leg unit and a buttocks unit. When the leg module is removed, the back module and the buttocks unit can be retained, which can better simulate the use scenario of drivers and passengers getting on and off the vehicle. It can not only simulate the impact of the artificial back on the seat back, but also simulate the impact of the buttocks on the side wings and core of the seat back, greatly improving the simulation effect.

Description

Technical Field

[0001] The present invention relates to the technical field of automobile seat test devices, in particular to a prosthetic buttock for moving in and out tests. Background Art

[0002] Car seats are an essential component of a vehicle, impacting both driver and passenger comfort and fatigue. Therefore, car seat durability is crucial. During car seat durability testing, a simulated manikin is often used to perform in-and-out tests, simulating real-world usage scenarios and assessing the durability of various seat components.

[0003] In the prior art, there are two types of mannequins used for seat in-and-out tests: one uses a single-piece dummy whose posture and center of gravity cannot be changed or shifted, and whose back and hip models cannot be separated, making it impossible to simulate back and leg usage scenarios separately. The other uses a dummy device with a detachable seat-hip module and backrest module. However, this device only allows the back and hip models to be separated, and cannot adjust the angle of the back model. Moreover, the seat-hip module in this technical solution is still a single-piece structure, which cannot better simulate real-world usage scenarios. Summary of the Invention

[0004] The purpose of the present invention is to provide a prosthetic buttocks for moving in and out tests. The prosthetic buttocks model adopts a split structure, which can better simulate the actual use scenario of the seat, so as to solve the technical problem of low simulation degree when conducting moving in and out tests in the prior art.

[0005] In order to solve the above technical problems, the present invention is implemented by adopting the following technical solutions:

[0006] A prosthetic hip for moving in and out testing includes a prosthetic back mechanism 10, a prosthetic hip mechanism 20, a back-hip connection mechanism 30, and a robot connection mechanism 40:

[0007] The bottom of the false back mechanism 10 is rotatably connected to the back-hip connection mechanism 30;

[0008] The tail of the artificial hip mechanism 20 is detachably connected to the back-hip connection mechanism 30;

[0009] The robot connection mechanism 40 is fixedly connected to the back-hip connection mechanism 30 , and is connected to the false back mechanism 10 via a telescopic mechanism 50 .

[0010] Furthermore, a transfer ear plate 11 is provided at the bottom of the false back mechanism 10 , and a cutout 31 is provided at the top of the back-hip connection mechanism 30 . The transfer ear plate 11 is inserted into the cutout 31 , and the two are connected by a rotating shaft 12 .

[0011] Furthermore, the tail of the artificial hip mechanism 20 is connected to the back-hip connection mechanism 30 via a guide rail mechanism, and is positioned by a positioning pin 23 passing through the back-hip connection mechanism 30 and the positioning holes 22 on the artificial hip mechanism 20.

[0012] Furthermore, the guide rail mechanism includes a guide groove 21 provided on the artificial hip mechanism 20 and a guide rail 32 provided on the back-hip connection mechanism 30 .

[0013] Furthermore, the robot connection mechanism 40 includes a robot connection part 41 and a prosthetic hip connection part 42, which are arranged perpendicular to each other; the robot connection part 41 is provided with a threaded hole 411 for connection with the robot.

[0014] Furthermore, the telescopic mechanism 50 includes an intermediate sleeve 51 provided with an internal thread, and both ends of the intermediate sleeve 51 are connected to telescopic rods 52 provided with external threads. The two telescopic rods 52 are respectively connected to the false back mechanism 10 and the robot connection mechanism 40.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The artificial buttocks for the moving in and out test proposed in the present invention adopts a split structural design, and the artificial buttocks mechanism adopts a connection and fixing method of guide rails and positioning pins, which is more convenient to disassemble; not only the back module and the buttocks module are separated, but the buttocks module is further separated into a leg unit and a buttocks unit, so that when the leg module is removed, part of the buttocks shape can be retained, which can better simulate the use scenario of drivers and passengers getting on and off the vehicle; when doing a separate artificial back moving in and out test, the buttocks unit can also be retained, which can not only simulate the influence of the artificial back on the seat back, but also simulate the influence of the buttocks on the side wings and core of the seat back, and the simulation effect is greatly improved.

[0038] In this embodiment, the tail end of the artificial hip mechanism 20 is connected to the back-hip connection mechanism 30 through a guide rail mechanism, and the guide rail mechanism includes a guide groove 21 arranged on the A surface of the artificial hip mechanism 20, and a guide rail 32 arranged on the bottom C surface of the back-hip connection mechanism 30. The A surface of the artificial hip mechanism 20 and the C surface of the back-hip connection mechanism 30 are tangent planes; the A surface of the artificial hip mechanism 20 is also provided with a positioning hole 22, and the C surface of the back-hip connection mechanism 30 is provided with a through hole 33, and the positioning pin 23 is passed through the through hole 33 and cooperates with the positioning hole 22 to realize the positioning of the tail end of the artificial hip mechanism 20 and the back-hip connection mechanism 30; when the artificial hip mechanism 20 needs to be removed, the positioning pin 23 is pulled out, and the artificial hip mechanism 20 can be slid out along the guide rail 32 on the bottom C surface of the back-hip connection mechanism 30.

[0039] See Figure 6 The robot connection mechanism 40 includes a robot connection part 41 and a fake hip connection part 42, which are arranged perpendicular to each other; the robot connection part 41 is a cylindrical structure, and its upper part is provided with four threaded holes 411 for connecting with the robot; the fake hip connection part 42 is a triangular block structure, and its tail end is provided with a connecting plate 421, and the connecting plate 421 is provided with threaded holes, which are connected to the threaded holes on the A surface of the back-hip connection mechanism 30 by bolts.

[0040] See Figure 7In this embodiment, the telescopic mechanism 50 includes an intermediate sleeve 51 with an internal thread, and the two ends of the intermediate sleeve 51 are respectively screwed to a telescopic rod 52 with an external thread on one end.
