Description

Technical Field

[0001] This utility model relates to the field of charger testing technology, specifically a charger testing device. Background Technology

[0002] Before leaving the factory, the charger must undergo a full-load long-term charging performance test. During the test, the current output is adjusted as needed to test whether the charger can carry out long-term charging under current changes, so as to prevent the product from malfunctioning after being installed in the vehicle for a long time.

[0003] Chinese Patent CN220603525U discloses a charger testing device, including a support plate with multiple resistors of different resistance values ​​horizontally fixed on it, each resistor having one end electrically connected to a socket; a switching component including a slide rail horizontally fixed to one end of the support plate, with a sliding table horizontally mounted on the slide rail; and a connecting component including a metal plate. This invention overcomes the problem of existing installation methods where workers wear insulated gloves and manually connect resistors of different resistance values ​​to the charger's power lines. This method is not only cumbersome and labor-intensive, but also poses safety hazards, such as the risk of electric shock during installation.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the resistors are exposed and there is no protective mechanism. They are easily damaged during long-term use. When the resistors are damaged, they cannot be replaced quickly, which affects the testing efficiency. Utility Model Content

Detailed Implementation

[0018] Example 1

[0019] like Figures 1 to 4 As shown, the present invention proposes a charger testing device, including a movable base 1, a second plug 202, a second socket 203, a resistor assembly, and a third plug 204. Multiple sets of first sockets 2 are evenly arranged at the bottom of the movable base 1, and the bottom ends of the multiple sets of first sockets 2 are connected to the first plugs 201 via wires. Multiple sets of second plugs 202 are arranged, and the second plugs 202 are adjustablely positioned at the top of the movable base 1 along its height direction. The multiple sets of second plugs 202 are evenly distributed on the movable base 1 and correspond to the first sockets 2. Multiple sets of second sockets 203 are evenly installed at the top of the movable base 1, and the second sockets 203 are positioned directly above the second plugs 202. The second plug 202 is connected to the corresponding second socket 203 via a wire. A support column 4 is installed at the center of the top of the movable base 1, and a mounting bracket 401 is installed at the top of the support column 4. Multiple sets of second sockets 203 are evenly distributed on the mounting bracket 401. Multiple sets of resistor components are provided, and the resistor components can be detachably installed between the corresponding first socket 2 and the second plug 202. The third plug 204 can be adjusted by the drive mechanism 6 on the movable base 1, which can rotate along the axis of the movable base 1 and adjust along the height direction of the movable base 1. The third plug 204 is plugged into the second socket 203. The top of the third plug 204 is connected to the fourth plug 205 via a wire. The drive mechanism 6 is installed at the top of the mounting bracket 401.

[0020] Furthermore, the movable seat 1 consists of two sets of mounting plates with different diameters and a vertical rod installed between the two sets of mounting plates. The bottom of the set of mounting plates with larger diameter is equipped with multiple sets of rubber wheels.

[0021] Furthermore, multiple sets of adjustment components are evenly arranged at the top of the movable base 1. The adjustment components consist of a movable plate 3 that is slidably connected to the top of the movable base 1 and a screw 301 that is rotatably connected to the top of the movable base 1. The movable plate 3 is L-shaped. One end of the movable plate 3 is slidably connected along the height direction of the top of the movable base 1. The other end of the movable plate 3 is connected to the second plug 202. The movable base 1 has a through hole corresponding to the second plug 202. The screw 301 is threadedly connected to the movable plate 3.

[0022] Furthermore, the resistor assembly includes a resistor frame 5 and a resistor body 501; a third socket 503 is installed at the top of the resistor frame 5 and a fifth plug 502 is installed at the bottom; the resistor body 501 is disposed inside the resistor frame 5, and the top of the resistor body 501 is connected to the third socket 503 through a wire, and the bottom of the resistor body 501 is connected to the fifth plug 502 through a wire, the third socket 503 is plugged into the second plug 202, and the fifth plug 502 is plugged into the first socket 2.

[0023] Furthermore, the drive mechanism 6 consists of a motor mounted on the top of the mounting bracket 401 on the movable seat 1, a long plate that is connected to the output end of the motor, a hydraulic rod mounted on the other end of the long plate, and a short plate mounted on the output end of the hydraulic rod. The third plug 204 is mounted on the other end of the short plate.

[0024] In this embodiment, the fifth plug 502 of the resistor assembly is plugged into the corresponding first socket 2. At the same time, the corresponding screw 301 is rotated. Since one end of the moving plate 3 is slidably connected along the height direction of the moving seat 1, when the screw 301 is rotated, the moving plate 3 moves upward along the moving seat 1, thereby driving the second plug 202 to move downward along the through hole on the moving seat 1 until the plug end of the second plug 202 is plugged into the third socket 503 of the resistor assembly. The resistor assembly can then be installed. In this way, other sets of resistor assemblies with different resistance values ​​are installed between the corresponding first socket 2 and the second plug 202. When the resistor assembly is damaged, the second plug 202 and the third socket 503 can be separated simply by reversing the screw 301, which makes it easier to remove the resistor assembly and install a new set of resistor assemblies between the second plug 202 and the first socket 2. Replacement is more convenient and quick, and avoids interfering with the normal detection of the charger.

[0025] The controller activates the drive mechanism 6, which rotates the third plug 204 to any suitable angle to match the corresponding second plug 202. Then, the drive mechanism 6 moves the third plug 204 down until it is plugged into the corresponding second plug 202. This working principle is consistent with that in the patent with authorization announcement number CN220603525U, and will not be described again. The fourth plug 205 is plugged into the charger to be tested, and the first plug 201 is plugged into the external power supply line to connect, thereby connecting the resistor components with suitable resistance values ​​in series. The current then passes through the resistor components to charge the charger.

[0026] Example 2

[0027] like Figure 1 As shown, the charger testing device proposed in this utility model, compared with Embodiment 1, also includes a protective box 7. The bottom of the protective box 7 is detachably connected to a set of mounting plates with a larger diameter by bolts. The top of the protective box 7 has a round hole corresponding to the wire on the fourth plug 205. Multiple sets of box doors 701 are evenly hinged around the side wall of the protective box 7. The box doors 701 correspond to the resistor components. In order to facilitate the heat dissipation of the resistor components, heat dissipation windows can be provided on the set of mounting plates with a larger diameter. A heat dissipation mechanism is provided on the inner wall of the protective box 7 to facilitate heat dissipation. This is prior art and is not shown.

[0028] In this embodiment, the protective box 7 is designed to protect multiple sets of resistor components, preventing damage from external forces and extending their service life. When the resistor components need to be replaced, simply open the latch between the corresponding box door 701 and the protective box 7, rotate the box door 701 to adjust the components, and then disassemble and replace the resistor components.

[0029] 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 thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
