Through flexible structure, it can adjust the form to adapt to different use scenarios, for example, folding when storing and unfolding into different support styles when using. In order to detect such a seat with high degrees of freedom so that it can meet the mechanical strength required by the user, it is necessary to test the load of the seat.

[0023] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0024] Embodiments of the present invention are described in detail below.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] A load-bearing testing device for a high-degree-of-freedom seat, such as Figures 1-9 As shown, the device includes a stable base 1 and a seat body 2 placed on the stable base 1; it also includes a clamping and stabilizing mechanism 3, a telescopic rod 4, a position adjustment mechanism 7, and a data acquisition device 8. Specifically, the clamping and stabilizing mechanism 3 is located on the stable base 1 and is used to clamp and stabilize the seat body 2; the telescopic rod 4 is located above the stable base 1, and its movable end has several telescopic rods 5, the movable end of which has a pressing element 6 that is in contact with the seat body 2; the position adjustment mechanism 7 has the telescopic rod 4 on it, and the position adjustment mechanism 7 is used to horizontally adjust the relative position between the telescopic rod 4 and the seat body 2; there are several data acquisition devices 8, which are respectively located around the seat body 2, and are used to monitor the deformation data of the seat body 2 after being subjected to pressure. In order to facilitate the control of the above electrical equipment, the device also includes a controller 49, which has a display screen 50. In use, a position adjustment mechanism 7 is installed above the stable base 1 to adjust the relative position between the telescopic rod 4 and the seat body 2. The telescopic rod 4 drives several telescopic rods 5 downwards. The controller 49 then drives the corresponding telescopic rods 5 to apply pressure to a selected area on the surface of the seat body 2. The data acquisition device 8 monitors the deformation data of the seat body 2 under pressure. During this process, the device can perform a load-bearing test on the selected area, thereby improving the seat's load-bearing strength data, making data collection more comprehensive, and enhancing the testing effect of the load-bearing testing device. To facilitate stable clamping of the seat body 2; such as Figure 3 as well as Figure 9 As shown, the clamping and stabilizing mechanism 3 includes a clamping plate 9, a sliding block 10, a hinged base 11, and a lower pressure plate 12. The stabilizing base 1 has two symmetrically arranged sliding grooves 13 located on both sides of the seat body 2. The sliding block 10 is slidably connected within the sliding grooves 13. The clamping plate 9 is located above the stabilizing base 1 and is in movable contact with the seat body 2. The hinged base 11 is located at the bottom of the stabilizing base 1 and is connected to the sliding block 10. Two lower pressure plates 12 are provided and symmetrically arranged at both ends of the clamping plate 9, and the lower pressure plates 12 are in movable contact with the seat body 2. Two stabilizing bars 14 are symmetrically connected to the stabilizing base 1. The two stabilizing bars 14 are respectively connected to one side of the two clamping plates 9. A sliding rod 15 is connected to the side of the clamping plate 9 near the stabilizing bar 14. The end of the sliding rod 15 away from the clamping plate 9 passes through the stabilizing bar 14, and the sliding rod 15 is slidably connected to the stabilizing bar 14. In use, the telescopic rod 3 16 can drive one end of the two connecting rods 19 to move synchronously, thereby driving the other end of the two connecting rods 19 to move synchronously, and driving the two clamping plates 9 to move synchronously. This allows the seat body 2 to be adjusted to the middle position of the stabilizing base 1 and clamp and stabilize the seat body, ensuring the stability of the seat body 2 when the telescopic rod 1 4 drives the telescopic rod 2 5 to perform a load-bearing test on the seat body 2.

[0026] To solve the problem of synchronous movement of the two sliding blocks 10 within the sliding groove 13; such as Figure 3 as well as Figure 9 As shown, the clamping and stabilizing mechanism 3 also includes a telescopic rod 16, a fixed plate 17, a hinge column 18, and a connecting rod 19; wherein, the telescopic rod 16 is installed at the bottom of the stabilizing base 1, the fixed plate 17 is connected to the movable end of the telescopic rod 16, the hinge column 18 is connected to the fixed plate 17, and there are two connecting rods 19, one end of each connecting rod 19 is rotatably connected to the two hinge bases 11 respectively, and the other end of each connecting rod 19 is rotatably connected to the hinge column 18.

[0027] Furthermore, the movable end of the telescopic rod 4 is connected to a mounting plate 20, and a laser emitter 21 is installed at the bottom of the mounting plate 20 for easy position adjustment and user observation. Several telescopic rods 5 are mounted longitudinally on the mounting plate 20, with the movable end of the telescopic rod 5 passing through the mounting plate 20. The pressing component 6 consists of a fixed plate 22, a pressure sensor 23, a contact plate 24, and a telescopic component. The fixed plate 22 is connected to the movable end of the telescopic rod 5, the pressure sensor 23 is mounted on the fixed plate 22, and the contact plate 24 is connected to the fixed plate 22 via the telescopic component. The contact plate 24 is in contact with the sensing end of the pressure sensor 23. The controller 49 can drive the corresponding telescopic rod 5 to apply pressure to a selected area on the surface of the seat body 2, and the pressure sensor 23 will detect the magnitude of the applied force in real time. The pressure sensor 23 transmits data to the controller 49, which then displays the data on the display screen 50. By setting several telescopic rods 2 5 at the movable end of the telescopic rod 1 4, the controller 49 can adjust the pressure applied to the seat body by each telescopic rod 2 5, thereby simulating the deformation of the seat body 2 under different pressures during actual use. Secondly, by setting the pressure sensor 23 at the movable end of the telescopic rod 2 5, the magnitude of the force applied to the seat body 2 by the telescopic rod 2 5 can be detected. Using the telescopic component, the contact plate 24 can be set on the sensing end of the pressure sensor 23. The end of the contact plate 24 facing the seat body 2 is made of soft material, ensuring that the seat body 2 will not be damaged when the telescopic rod 2 5 drives the pressure sensor 23 to contact the seat body 2.

The end of the extension rod 28 away from the sleeve 26 is connected to the contact plate 24. When the contact plate 24 is subjected to pressure, the extension rod 28 will slide axially within the sleeve 26. When the contact plate 24 moves away from the seat body 2, the extension rod 28 returns to its initial position under the action of the spring 27.

[0030] In order to allow the load plate 30 to slide stably on the square frame 29; therefore, as Figure 6 As shown, two sliding rails 40 are symmetrically arranged on the square frame 29, and the two sliding rails 40 correspond to the load plates 30 on the two transverse adjustment parts respectively. One end of the load plate 30 is slidably connected to the sliding rail 40. An auxiliary wheel 41 is rotatably connected to the side of the load plate 30 near the square frame 29.
