DETAILED DESCRIPTION

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] The fuel cell test fixture of this utility model is described below with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, the fuel cell test fixture of this utility model embodiment includes: a housing 1, an adjustment component 2, a clamping component 3, and a mounting bracket 4.

[0023] The housing 1 has an internal mounting groove 11, the adjustment component 2 is located inside the mounting groove 11, and the clamping component 3 is located on the adjustment component 2.

[0024] The clamping assembly 3 includes a push plate 31, a buffer assembly 32, and a baffle 33.

[0025] Among them, the push plate 31 is set on the adjustment component 2, the buffer component 32 is set on the side wall of the push plate 31, and the baffle 33 is set on the mounting bracket 4.

[0026] The buffer assembly 32 includes multiple sets of storage columns 321, multiple sets of springs 322, multiple sets of connecting columns 323, and clamping plates 324.

[0027] Multiple sets of storage columns 321 are equidistantly distributed on the side wall of the push plate 31, multiple sets of springs 322 are respectively sleeved on the outside of the corresponding storage column 321, and one end of the spring 322 is fixed to the side wall of the push plate 31. Multiple sets of connecting columns 323 are respectively connected to the other end of the corresponding spring 322, and the clamping plate 324 is connected to the other end of the multiple sets of connecting columns 323.

[0028] Mounting bracket 4 is disposed on the side wall of housing 1.

[0029] It should be noted that the inner wall depth of the storage column 321 described in this embodiment should be slightly greater than the compressed length of the spring 322. At the same time, the height of the connecting column 323 plus the fully compressed length of the spring 322 should not exceed the internal depth of the storage column 321. For example, if the internal length of the storage column 321 is 10 cm, then the length of the spring 322 should be about 8 cm. In this way, the extra 2 cm inside the storage column 321 can limit the connection column 323, and the spring 322 will not deform due to the connection column 323 at the front end, thereby changing the movement trajectory of the connection column 323.

[0030] Meanwhile, if the height of the spring 322 after being completely accommodated is 2 cm, the length of the connecting column 323 should be no more than 8 cm, so that the connecting column 323 can be completely accommodated in the accommodation column 321.

[0031] Specifically, when the fuel cell is detected, the relevant staff first abuts the fuel cell on the side of the baffle 33, and then the relevant staff starts the adjusting assembly 2 by means of an external control device, the adjusting assembly 2 drives the baffle 33 to move horizontally, when the clamp plate 324 abuts against the fuel cell, the adjusting assembly 2 continues to force the spring 322 to compress, and at the same time the connecting column 323 moves inward along the inner wall of the accommodation column 321 and is accommodated in the accommodation column 321, the adjusting assembly 2 is closed, the spring 322 rebounds and drives the connecting column 323 to move outward along the inner wall of the accommodation column 321, the fuel cell is clamped by the baffle 33 and the clamp plate 324, and the spring 322 is arranged, so that the baffle 33 and the clamp plate 324 can clamp the fuel cell more tightly, and at the same time, the adjusting assembly 2 can prevent the clamp plate 324 from directly clamping the fuel cell, so as to cause damage to the fuel cell.

[0032] In an embodiment of the utility model, as shown in Figure 2 and Figure 3 The adjusting assembly 2 comprises a driving part 21, a base 22 and a pushing part 23.

[0033] The driving part 21 is installed in the mounting groove 11, the base 22 is connected with the output end of the driving part 21, and the pushing part 23 is installed in the base 22.

[0034] The bearing 6 penetrates the mounting frame 4, and the inner wall of the bearing 6 is connected with the baffle 33.

[0035] It should be noted that the driving part 21 described in the embodiment is a driving motor, and the pushing part 23 is an electric push rod.

[0036] Specifically, when the fuel cell needs to be clamped, the relevant staff first opens the pushing part 23, the pushing part 23 drives the pushing part 23 to move, and the fuel cell is clamped, when the angle of the clamped fuel cell needs to be rotated, the relevant staff can open the driving part 21, the driving part 21 drives the base 22 and the driving part 21 to rotate, so as to drive the pushing part 23 to rotate, and through the arrangement of the bearing 6, the baffle 33 can rotate with the fuel cell in the process of rotating.

[0037] In an embodiment of the utility model, as shown in Figure 4 The outer part of the baffle 33 is provided with a non-slip pad 7.

[0038] It can be understood that the non-slip pad 7 can increase the friction between the baffle 33 and the fuel cell.

[0039] In one embodiment of the present application, as shown in Figure 2 The mounting rack 4 and the shell 1 are symmetrically arranged with the anti-skid foot pad 5 respectively.

[0040] It can be understood that, through the arrangement of the anti-skid foot pad 5, the frictional force between the mounting rack 4 and the shell 1 and the ground or the detection machine operating platform can be increased.

[0041] In conclusion, the fuel cell test fixture can buffer the force applied when the clamping plate contacts the fuel cell during the clamping process of the fuel cell, and then transmit the force to the fuel cell, thereby avoiding damage to the fuel cell caused by the direct contact of the externally applied force.
