[0028] The present invention is further described in detail below in conjunction with the accompanying drawings. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The terms such as "upper", "lower", "left", "right", "middle" and the like cited in this specification are for the convenience of description and are not used to limit the scope of the present invention. The change or adjustment of the relative relationship shall also be regarded as the scope of the present invention without substantially changing the technical content.

[0029] Example:

[0030] like Figure 1 and Figure 2 As shown, a folding screen mobile phone testing device designed in the present invention includes a mounting seat and a testing mechanism 1. The testing mechanism 1 includes a base 11 and two mounting plates 12 connected in parallel to both sides of the base 11. The testing mechanism 1 includes a fixed clamping mechanism 2 and a floating clamping mechanism 3. One side of the folding screen 6 is clamped on the fixed clamping mechanism 2, and the other side is clamped on the floating clamping mechanism 3. The lower surface of the fixed clamping mechanism 2 is fixedly connected to the base 11, and the two mounting plates 12 are connected to a driving component 4 that drives the floating clamping mechanism 3 to rotate.

[0031] like Figure 2 As shown, the driving assembly 4 includes a driving motor 42 and two sets of transmission assemblies 41. The transmission assembly 41 includes a driving wheel 413 and a driven wheel 414. The driving wheel 413 and the driven wheel 414 are driven by a belt 415. A transmission rod 412 is coaxially fixed between the two driving wheels 413. The rotor of the driving motor 42 passes through the mounting plate 12 and is coaxially fixed to the left driving wheel 413. A connecting rod 43 is coaxially fixed to each other on one side of the two sets of driven wheels 414. The top ends of the two connecting rods 43 are respectively connected to the two ends of the floating clamping mechanism 3 through linear bearings 44.

[0032] like Figure 2 and Figure 3 As shown, the floating clamping mechanism 3 includes a clamping body 31 and a stopper 32. The two ends of the clamping body 31 in the length direction are respectively connected to two linear bearings 44. The linear bearing 44 is connected to the clamping body 31 through a rotating shaft 441. The rotating shaft 441 passes through the clamping body 31 and is fixed by a retaining spring 442. A clamping groove 411 is provided on the clamping body 31. The side of the folding screen 6 away from the fixed clamping mechanism 2 is located in the clamping groove 411. The stopper 32 is detachably connected to the clamping body 31 and the lower surface abuts against the upper surface of the screen near the edge.

[0033] like Figure 4 As shown, the fixed clamping mechanism 2 includes a clamping plate 21 and a clamping member 22. A first air hole 211 is provided on the upper surface of the clamping plate 21, and a second air hole 212 is provided on the side wall of the clamping plate 21. A vacuum air path is formed between the first air hole 211 and the second air hole 212. A sealing member 213 is provided on the upper surface of the clamping plate 21 around the first air hole 211. The sealing member 213 is a rubber ring and fits the lower surface of the product. Two clamping members 22 are provided and symmetrically connected to both ends of the clamping plate 21 in the length direction. The clamping members 22 slide along the length direction of the clamping plate 21, and a wedge-shaped surface 221 is formed at the connection between the two clamping members 22 and the bottom wall on one side close to each other, and the wedge-shaped surface 221 abuts against the edge of the folding screen 6.

[0034] like Figures 2 to 5 As shown, two sensors 111 are installed on the bottom plate on both sides of the length direction of the fixed clamping mechanism 2, and the tops of the two connecting rods 43 are connected with sensor baffles 45. The sensor baffles 45 include a connecting portion 451 and a vertical portion 452. The connecting portion 451 is provided with a waist-shaped hole 453 and is connected to the connecting rod 43 by a bolt 431. A sensing groove 112 is formed on the top wall of the sensor 111. The sensor 111 is configured as an infrared sensor 111 and the sensing position is configured in the sensing groove 112. The sensor baffle 45 is inserted into the sensing groove 112 during the rotation process.

[0035] like Figures 2 to 5As shown, when the floating clamping mechanism 3 rotates with the driven wheel 414, when the folding screen 6 is in the folded state, the vertical portion 452 of the sensor baffle 45 moves to the sensing slot in front of the fixed clamping mechanism 2, and the infrared rays are interrupted by the sensor baffle 45. The sensor 111 sends a signal to drive the motor 42 to rotate in the opposite direction until the vertical portion 452 rotates to another sensing slot 112 to perform the same sensing process. The sensor baffle 45 is vertically connected to one side of the length direction of the connecting portion 451, and the waist-shaped hole 453 is arranged along the length direction of the connecting portion 451. When the bolt 431 is centrally inserted into the waist-shaped hole 453, the rotation angle of the connecting rod 43 to both sides is 90°, and a conventional 180° folding test can be performed; when the bolt 431 is inserted into the end of the waist-shaped hole 453, the rotation angle of the connecting rod 43 to one side is greater than 90°, and the hinge overload capacity can be tested.

[0036] like Figure 1 As shown, the base 11 is connected to the tray 5, and connecting rails 51 are formed on both sides of the tray 5. The tray 5 is a carbon fiber board, which has the characteristics of light weight and good light transmission. The connecting rails 51 on both sides of the carbon fiber board can be used to place the device in the X-ray detection equipment to observe the changes in the internal structure of the mobile phone during the folding process under X-ray. The drive motor 42 is powered by the electrical box 53, and an electrical connection terminal block 52 is installed on the tray 5. The electrical box and the electrical connection terminal block 52 are connected by a cable. The electrical box is connected to the touch screen controller 7 through a cable to control the whole. The mounting plate 12 is connected to a pressure wheel 121, and the pressure wheel 121 is in contact with the upper surface of the belt 415.

[0037] The implementation principle of the above embodiment is: the folding screen 6 is placed on the test mechanism 1, with one side of it located on the clamping plate 21, and the edge of the other side located in the clamping groove 411 on the clamping body 31, and a vacuum is drawn at the second air hole 212, and the seal 213 cooperates with atmospheric pressure to assist in fixing the mobile phone, and then the clamping member 22 is moved to make the wedge surface 221 abut against the edge of the folding screen 6, so that the linear bearing 44 moves along the connecting rod 43, driving the edge of the clamping groove 411 in the length direction to fit the upper surface of the folding screen 6, so that the limit member 32 presses the upper surface of the folding screen 6, and the position of the vertical portion 452 can be adjusted by adjusting the position of the bolt 431 inserted from the waist-shaped hole 453.

[0038] Start the driving motor 42, and the two active wheels 413 rotate synchronously driven by the transmission rod 412, so that the connecting rod 43 drives the clamping body 31 to move, and drives the folding screen 6 to open and close. When the clamping body 31 drives the screen to fold, the sensor baffle 45 is inserted into a sensor slot 112. After the sensor 111 senses the reverse rotation of the rear driving motor 42, the sensor baffle 45 is driven to insert into another sensor slot 112. The position of the sensor baffle 45 is adjusted by adjusting the position of the bolt 431 in the waist-shaped hole 453. When the sensor 111 is positioned backward, the folding angle of the folding screen 6 can be driven to exceed 180°, so as to test the overload capacity of the hinge of the folding screen 6.

[0039] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
