Description

Technical Field

[0001] This utility model relates to the field of charging gun insertion and removal testing devices, and in particular to a charging gun insertion and removal durability testing device. Background Technology

[0002] With the increasing popularity of electric vehicles (EVs), the construction of charging infrastructure has become an important part of promoting the development of the electric vehicle industry. As a key component connecting electric vehicles and charging piles, the performance of the charging gun directly affects the charging efficiency and the user experience of electric vehicles.

[0003] Because existing charging guns come in various models, testing them typically requires replacing the equipment based on the specific gun model, resulting in significant costs. Furthermore, the inconvenience of quickly replacing the charging gun during use leads to considerable time wastage during the plugging and unplugging durability test.

[0004] Therefore, those skilled in the art have provided a charging gun insertion and removal durability testing device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a charging gun insertion and removal durability testing device. This device uses a unidirectional threaded rod to move the device, allowing for adjustment of the front-to-back distance based on the length of different charging gun models during use. A bidirectional threaded rod works in conjunction with a clamping block; rotating the bidirectional threaded rod enables quick replacement of the charging gun and also allows for clamping different models of charging guns.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A charging gun insertion and removal durability test device includes a base, a moving mechanism is provided inside the base, the moving mechanism includes a one-way threaded rod, the one-way threaded rod is rotatably provided inside the base, a threaded block is threadedly connected to the outer side of the one-way threaded rod, a connecting rod is fixedly provided at the top of the threaded block, and a moving seat is fixedly provided at the top of the connecting rod.

[0008] The above technical solution enables the charging gun to move back and forth during use, thereby simulating the insertion and removal motion of the charging gun. The device is moved by a one-way threaded rod, allowing the device to be adjusted back and forth according to the length of different models of charging guns during use.

[0009] Furthermore, a clamping mechanism is fixedly provided at the top of the movable seat. The clamping mechanism includes a fixed seat. A fixed seat is fixedly provided at the top of the movable seat. A bidirectional threaded rod is rotatably provided inside the fixed seat. Two clamping blocks are threadedly connected to the outer side of the bidirectional threaded rod.

[0010] The above technical solution utilizes a bidirectional threaded rod in conjunction with a clamping block. Rotating the bidirectional threaded rod allows for quick replacement of the charging gun and enables clamping of different models of charging guns.

[0011] Furthermore, a protective frame is fixedly installed at the top of the base, a counter is fixedly installed inside the protective frame, and a test platform is fixedly installed at the rear end of the base.

[0012] By using the above technical solution, the counter is installed inside the protective frame. When the charging gun is inserted, the lower end of the counter will rise, thus completing one count, which allows for more direct counting.

[0013] Furthermore, the test bench is equipped with testing instruments, including a tester. The tester is fixedly installed inside the test bench, a controller is fixedly installed on the top of the base, and a control board is fixedly installed on the front face of the protective frame.

[0014] Through the above technical solution, the pressure and resistance of the charging gun can be tested using the tester, and the controller can easily control the motor, enabling the charging gun to simulate plugging and unplugging actions.

[0015] Furthermore, the base is provided with a limiting mechanism, which includes a sliding groove. Sliding grooves are provided on both inner sides of the base, and sliding rods are slidably provided on the inner sides of both sliding grooves.

[0016] The above technical solution, which uses the sliding rod and the sliding groove together, can make the charging gun more stable during movement, and avoid the charging gun from deviating during movement, which would prevent the charging gun from making accurate contact with the tester.

[0017] Furthermore, a protective door is fixedly installed on the front end face of the protective frame. The protective door includes hinges. Two pairs of hinges are fixedly installed on the front end face of the protective frame. A box door is fixedly installed on the rear end face of each pair of hinges. A handle is fixedly installed on the front end face of each of the two box doors.

[0018] By using the above technical solution, installing a protective door can prevent the charging gun from being overcharged during the test due to unexpected circumstances, thus avoiding the interruption of the test.

[0019] Furthermore, a protective box is installed at the bottom of the test bench, and a motor is fixedly installed at the bottom of the protective box.

[0020] The above technical solution uses a motor to drive a one-way threaded rod to move, thereby enabling the charging gun to move back and forth.

[0021] This utility model has the following beneficial effects:

[0022] 1. The present invention proposes a charging gun insertion and removal durability testing device. A moving mechanism is installed inside the base to allow the charging gun to move back and forth during use, thereby simulating the insertion and removal motion of the charging gun. Since a one-way threaded rod is used to drive the device to move, the device can be adjusted back and forth according to the length of different models of charging guns during use. At the same time, a two-way threaded rod and a clamping block are used in conjunction at the clamping position of the charging gun. Rotating the two-way threaded rod allows for quick replacement of the charging gun, and can also clamp different models of charging guns.

[0023] 2. The charging gun insertion and removal durability test device proposed in this utility model uses a counter installed inside the protective frame, which provides more direct data than infrared measurement and avoids inaccurate insertion and removal counts during the test, thus affecting the final test results. At the same time, sliding rods are installed on both sides of the threaded block and used in conjunction with the sliding groove, which can make the charging gun more stable during movement and prevent the charging gun from deviating during movement, thus preventing the charging gun from making accurate contact with the tester.

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 6A clamping mechanism 3 is fixedly installed at the top of the movable seat 204. The clamping mechanism 3 includes a fixed seat 301. The fixed seat 301 is fixedly installed at the top of the movable seat 204. A bidirectional threaded rod 302 is rotatably installed inside the fixed seat 301.

[0037] Working principle: During use, first use handle 903 to open the protective door 9, then use control board 703 to move the moving mechanism 2 backward to facilitate the installation of the charging gun into the clamping mechanism 3. During movement, motor 10 drives the one-way threaded rod 201 to rotate, causing the one-way threaded rod 201 to engage with the threaded block 202, thereby driving the moving seat 204 to move. Then, the clamping mechanism 3 can be moved together. When in use, first rotate the two-way threaded rod 302 to increase the distance between the clamping blocks 303, then install the charging gun between the clamping blocks 303 and place it in the correct position. Then, the charging gun is clamped using the bidirectional threaded rod 302. After the charging gun is installed, the protective door 9 is closed. Then, the motor 10 is controlled using the control board 703. The charging gun is inserted once and the position is recorded. Then, it is withdrawn a little away from the counter 5 and the position is recorded. This can greatly reduce the movement trajectory during the test. During the test, the pressure and resistance of the charging gun are tested using the tester 701. The number of insertions and removals is recorded using the counter 5 during the insertion and removal process, which facilitates the recording of the test data of the charging gun.
