DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] As mentioned in the background art, in order to solve the problem that the testing platform in the prior art is inconvenient for cleaning debris and collecting defective products, the present invention provides a testing platform for measuring the pressure resistance of the back panel of an electronic device.

[0024] Example 1

[0025] Reference Figures 1 to 3 A test bench for measuring the pressure resistance of the back panel of an electronic device comprises a fixed box 1, a mounting frame 2 is provided on the top of the fixed box 1, a cylinder 3 is provided on the mounting frame 2, a pressure sensor 4 is connected to the piston rod of the cylinder 3, an extrusion block 5 is provided on the pressure sensor 4, a display screen 6 and a control button 7 are provided on the mounting frame 2, the back panel of the electronic device is placed on the top of the fixed box 1, the cylinder 3 is controlled to extend by the control button 7, so that the pressure sensor 4 drives the extrusion block 5 to perform an extrusion test on the back panel, the pressure data during the extrusion is displayed on the display screen 6, the extrusion is stopped when the extrusion requirement is met, and the back panel is observed for cracks, scratches and debris collapse. If there are no cracks, scratches and debris collapse, the product is qualified, and if there are, the product is unqualified.

[0026] The front side of the fixed box 1 is slidably connected to a drawer 9, which can be opened to collect defective products.

[0027] A clamping assembly is provided on the fixed box 1;

[0028] U-shaped baffles 13 are provided on the front and rear sides of the top of the fixed box 1. The opposite sides of the baffles 13 on both sides are connected to the installation frame 2, and the baffles 13 are transparent structures. The transparent structure does not affect the user's observation and inspection situation. The debris of the unqualified back panel when it breaks can be blocked by the front and rear baffles 13 and the installation frame 2 to prevent the debris from flying out and leave the debris on the top of the fixed box 1, which is more labor-saving to clean up.

[0029] A push rod 14 slides through the bottom of the rear baffle 13, and the bottom of the push rod 14 is fitted and connected to the fixed box 1. An electric telescopic rod 15 is provided on the rear side of the fixed box 1, which is controlled by the control button 7. The output end of the electric telescopic rod 15 is connected to the push rod 14, and a through slot 16 is provided on the top of the fixed box 1, and the front side of the through slot 16 is aligned with the horizontal inner wall of the front baffle 13. The horizontal length of the through slot 16 and the push rod 14 is the same as the horizontal length of the inner wall of the baffle 13. In this way, the electric telescopic rod 15 drives the push rod 14 to move forward, and the debris falling on the top of the fixed box 1 can be pushed into the through slot 16 and then fall into the drawer 9, so that it can be directly collected through the drawer 9, making cleaning more labor-saving.

[0030] The left and right inner walls of the blocking frame 13 are aligned with the inner walls of the mounting frame 2 , so that the push rod 14 is not hindered when moving forward and backward and can push away all the debris.

[0031] The clamping assembly includes a screw 10 that passes horizontally through both sides of the mounting frame 2. The screw 10 is connected to a clamping plate 11 through a bearing. A slide 12 that passes horizontally through the mounting frame 2 is provided on the clamping plate 11. The back panel does not need to be clamped when it is placed flat. When the back panel is placed sideways or vertically for pressure resistance testing, in order to ensure the stability of the back panel, the screw 10 can be rotated so that the clamping plate 11 is guided by the slide 12 and then moved horizontally, thereby fixing the back panel.

[0032] The top of the push rod 14 is lower than the clamping plate 11 , so that the push rod 14 can move from under the clamping plate 11 .

[0033] Example 2

[0034] Reference Figure 1 , mounting plates are provided around the fixed box 1 for fixing the fixed box 1 on the rack.

[0035] The rest of the structure is the same as that of Example 1.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
