[0002] The charging port is an important connection interface between electronic devices and charging devices. The plug and unplug test of the charging port is an important test for evaluating the quality and reliability of the connection interfaces of various electronic devices and charging devices. The formulation of the plug and unplug test requirements standards is to ensure that the charging port has good connection performance and service life to meet the daily use needs of users. At the same time, the charging port plug and unplug test requirements standards can also help manufacturers improve product quality and reduce after-sales maintenance costs.

[0003] Before the shopping cart PAD is launched on the market, a plug and unplug life test of the charging socket will be carried out. The traditional plug and unplug test of the charging interface is a single linear reciprocating plug and unplug action, which cannot truly simulate the real charging action of the existing shopping cart PAD. Therefore, the utility model provides a PAD durability test device to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to provide a PAD durability test device, which adds the inclined insertion of the charging socket of the shopping cart PAD to the plug and unplug action of the shopping cart PAD, presses the shopping cart PAD to ensure good contact with the charging base, and truthfully reflects the plug and unplug state. The plug and unplug life obtained by the device is closer to the actual application environment than that of the traditional single reciprocating linear plug and unplug tooling.

[0005] To achieve the above purpose, a PAD durability test device is provided, which includes a bottom plate. A charging base and a guide plate are fixedly connected to the top of the bottom plate. A lifting component is arranged on the side of the guide plate away from the charging base. The lifting component includes a moving plate connected movably. A support plate is fixedly connected to the top of the moving plate. A top plate is fixedly connected to the top of the support plate. Two connecting ropes are symmetrically and fixedly connected inside the top plate. The bottoms of the two connecting ropes are both connected with a hanging ring movably. The two hanging rings are jointly connected with a shopping cart PAD movably. A charging socket is arranged on the side of the shopping cart PAD close to the charging base. A pressing component for pressing the shopping cart PAD is arranged at the bottom of the support plate and above the shopping cart PAD.

[0006] According to the described PAD durability test device, the lifting component further includes a mounting frame fixedly connected to one side of the guide plate and arranged in a C-shaped structure, a lead screw rotatably connected inside the mounting frame, and a motor fixedly connected to the bottom of the mounting frame. The bottom of the lead screw penetrates through the mounting frame and is fixedly connected to the output shaft of the motor. The moving plate is threadedly connected to the lead screw.

[0018] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0019] Refer toFigures 1-3 , in an embodiment of the present utility model, a PAD durability test device includes a bottom plate 1. A charging base 2 and a guide plate 3 are fixedly connected to the top of the bottom plate 1. A lifting assembly is provided on one side of the guide plate 3 away from the charging base 2. The lifting assembly includes a moving plate 7 connected movably. A support plate 9 is fixedly connected to the top of the moving plate 7. A top plate 10 is fixedly connected to the top of the support plate 9. Two connecting ropes 13 are symmetrically and fixedly connected inside the top plate 10. Suspension rings 14 are movably connected to the bottoms of the two connecting ropes 13. A shopping cart PAD 8 is movably connected by the two suspension rings 14. A charging socket 15 is provided on one side of the shopping cart PAD 8 close to the charging base 2. A pressing assembly for pressing the shopping cart PAD 8 is provided at the bottom of the support plate 9 and above the shopping cart PAD 8. The shopping cart PAD 8 is installed on the suspension rings 14 and above the card slot of the charging base 2. When the moving plate 7 in the lifting assembly moves downward, it drives the shopping cart PAD 8 to move into the card slot of the charging base 2. When the moving plate 7 continues to move downward, the shopping cart PAD 8 loses the pulling force of the connecting rope 13 and tilts towards the charging base 2, so that the charging socket 15 is connected to the charging base 2. At the same time, under the action of the pressing assembly, the charging socket 15 can be made to complete contact with the base of the charging base 2 to ensure the stability of the connection. After the operation is completed, the moving plate 7 moves upward to drive the shopping cart PAD 8 to move upward, so that the charging socket 15 is separated from the charging base 2, and then the charging socket 15 is controlled to move downward to contact the charging base 2. By cycling in turn, the plugging and unplugging life test of the shopping cart PAD 8 can be completed. The operation is simple, and the plugging and unplugging life obtained by the traditional single reciprocating linear plugging and unplugging tooling is closer to the actual application environment.

[0020] The lifting assembly further includes a mounting frame 4 fixedly connected to one side of the guide plate 3 and having a C-shaped structure, a lead screw 5 rotatably connected inside the mounting frame 4, and a motor 6 fixedly connected to the bottom of the mounting frame 4. The bottom of the lead screw 5 penetrates the mounting frame 4 and is fixedly connected to the output shaft of the motor 6. The moving plate 7 is threadedly connected to the lead screw 5. The moving plate 7 is slidably connected to the mounting frame 4. When the motor 6 operates, it drives the lead screw 5 to rotate. Under the action of the rotating lead screw 5, the up and down movement operation of the moving plate 7 can be realized. Thus, when the moving plate 7 moves downward, the shopping cart PAD 8 loses the pulling force of the connecting rope 13 and tilts towards the charging base 2.

[0021] The pressing assembly includes a guide rod 11 slidably connected inside the support plate 9 and a pressing block 12 fixedly connected to the bottom of the guide rod 11. The guide rod 11 can be inserted into the support plate 9 with interference fit. At the same time, the guide rod 11 can move up and down inside the support plate 9. By pressing down the guide rod 11, the pressing block 12 can be driven to move downward. By the downward moving pressing block 12, the tilted shopping cart PAD 8 can be pushed to move downward so that the charging socket 15 is connected to the charging base 2.

[0022] Working principle: The shopping cart PAD8 is installed on the hanging ring 14 and is located above the card slot of the charging base 2. When the motor 6 operates, the lead screw 5 rotates. Under the action of the rotating lead screw 5, the moving plate 7 can be driven to move downward. The downward movement of the moving plate 7 drives the shopping cart PAD8 to move into the card slot of the charging base 2. The continuous downward movement of the moving plate 7 can cause the shopping cart PAD8 to lose the pulling force of the connecting rope 13 and tilt towards the charging base 2, so that the charging socket 15 is connected to the charging base 2. At the same time, by pressing down the guide rod 11, the pressing block 12 can be driven to move downward. The downward movement of the pressing block 12 can push the tilted shopping cart PAD8 downward to make the charging socket 15 better connected to the charging base 2;

[0023] After the operation is completed, the moving plate 7 moves upward to drive the shopping cart PAD8 to move upward, so that the charging socket 15 is separated from the charging base 2. Then, the charging socket 15 is controlled to move downward to contact the charging base 2. By cycling in this way, the plug and unplug life test of the shopping cart PAD8 can be completed. The operation is simple, and the plug and unplug life obtained is closer to the actual application environment than that of the traditional single reciprocating linear plug and unplug tooling.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present invention.
