The shielding mechanism 6 is adjusted according to the motor position to shield the untested area. The test assembly 7 is then adjusted to test the car battery. After the test is complete, the control mechanism 3 is activated, which drives the placement mechanism 4 outside the body 1. The car battery is manually removed, and the contact assembly 303 is adjusted to facilitate cooling of the bottom plate 306.

[0022] The control mechanism 3 also includes: The slide 301 is provided inside the workbench 2, the first slider 302 is slidably connected to the inside of the slide 301, the groove 304 is provided inside the workbench 2, and there are two slides 301 and two first sliders 302. The first slider 302 is provided with a power system inside. The bottom plate 306 is connected to the first slider 302. The top of the bottom plate 306 is connected to an ear plate 307. Two ear plates 307 are provided and are symmetrically arranged. A through slot 309 is opened inside the bottom plate 306. A first lifting rod 308 is installed inside the ear plate 307 and is connected to the placement mechanism 4. The first slider 302 drives the contact assembly 303, the bottom plate 306, the first lifting rod 308, and the placement mechanism 4 to move, controlling whether the placement mechanism 4 is inside the housing 1. A first fixing groove 310 is provided inside the ear plate 307 , and a first push rod 311 is installed inside the first fixing groove 310 ; A first movable box 312 is connected to the first push rod 311.

The first channel 313 is opened inside the first moving box 312 .

[0023] Before using the device, the power system in the first slider 302 is turned on, and the first slider 302 begins to move in the slide 301, thereby driving the contact component 303 and the placement mechanism 4 to move until the placement mechanism 4 is outside the body 1.

[0024] Open the first lifting rod 308, which drives the placement mechanism 4 to move upward. Then manually place the car battery on the bottom plate 306. The car battery fits into the ear plate 307 on the side away from the first movable box 312. Adjust the placement mechanism 4 to fix the position of the car battery.

[0025] At the same time, the first push rod 311 is opened, and the first push rod 311 drives the first movable box 312 to move toward the car battery until the first rubber rod 315 outside the first movable box 312 contacts the car battery, so that the car battery and the ear plate 307 are more closely fitted.

[0026] During the test, the first telescopic column 314 is opened periodically to drive the first contact head to contact the car battery, and the car battery temperature is measured in real time. When the car battery temperature is higher than the normal value, the test is stopped and the car battery is surrounded and protected.

[0027] After the test, the placement mechanism 4 is adjusted again until the placement mechanism 4 is outside the body 1, the first lifting rod 308 is opened, and the assembly is placed away from the bottom plate 306. At this time, the car battery is manually removed, and the contact assembly 303 is opened to clean the bottom plate 306 and dissipate heat.

[0028] By providing a control mechanism 3, the vehicle battery is placed and its position is controlled. Both placement and removal of the vehicle battery are completed outside the housing 1, facilitating ventilation and heat dissipation at the location where the vehicle battery is placed. Furthermore, by providing a first movable box 312 and a first contact head, a first rubber rod 315 on the exterior of the first movable box 312 contacts one end of the vehicle battery, allowing for regular contact temperature measurement of the vehicle battery. If the temperature exceeds the normal value, a shielding mechanism 6 is used to shield and protect the vehicle battery.

A contact column 3034 is installed at the bottom of the third push rod 3033. A heat conducting rod is provided on the outside of the contact column 3034.

[0030] During the test, the second push rod 3031 is in the initial state, and the third push rod 3033 is opened to the second stroke. At this time, the third push rod 3033 drives the contact column 3034 to move into the groove 304, opens the cooling plate 305, and the temperature is gradually transferred to the heat-conducting rod outside the contact column 3034, and the temperature of the heat-conducting rod decreases.

[0031] After removing the car battery, adjust the third push rod 3033 to its initial position, driving the contact pin 3034 back to its original position. Then, activate the second push rod 3031 to its first stroke, driving the movable rod 3032, the third push rod 3033, and the contact pin 3034 to move above the bottom plate 306. Then, activate the third push rod 3033 to its first stroke, driving the contact pin 3034 downward, until the contact pin 3034 contacts the upper surface of the bottom plate 306. The second push rod 3031 is adjusted to reciprocate between the first and second strokes, causing the heat-conducting rod on the outside of the contact pin 3034 to drive impurities downward through the through slot 309. The heat-conducting rod then begins to transfer heat to the bottom plate 306, cooling it down.

[0032] The contact assembly 303 is used to cool and clean the bottom plate 306 where the car battery is placed. Adjusting the stroke of the third push rod 3033 and the second push rod 3031 controls the movement of the contact pin 3034 and the heat-conducting rod outside the contact pin 3034. The heat-conducting rod transfers the temperature to the bottom plate 306, driving impurities on the bottom plate 306 downward through the through slot 309.

[0033] The placement mechanism 4 includes: A top plate 401 is mounted on the top of the first lifting rod 308. A support plate 403 is mounted on the bottom of the top plate 401.

A third channel 407, the third channel 407 is opened inside the second moving box 406; The second rubber rod 409 is installed on the outside of the second moving box 406. There are multiple second rubber rods 409, which are evenly arranged.

[0034] When fixing the position of the car battery, the fourth push rod 405 is opened, and the fourth push rod 405 drives the second movable box 406 and the second rubber rod 409 to move toward the car battery, and pushes the car battery to move toward the support plate 403 until the car battery is in contact with the support plate 403.

[0035] During the test, the second telescopic column 408 is opened periodically to drive the second contact head to contact the car battery, and the car battery temperature is measured in real time. When the car battery temperature is higher than the normal value, the test is stopped and the car battery is surrounded and protected.

[0036] Before the test, no blocking plate is placed inside the second channel 402. According to the position of the automobile battery electrode, the test assembly 7 is adjusted so that the test head in the test assembly 7 is aligned with the second channel 402 and the electrode position. The shielding mechanism 6 is adjusted to shield the untested area. For the second channel 402 that is outside the test position and is not protected by the shielding mechanism 6, the blocking plate is manually installed in the corresponding second channel 402.

[0037] Then, the power system in the test assembly 7 is turned on, so that the test head in the test assembly 7 contacts the battery electrodes, and the voltage and current of the battery are tested.

[0038] When the first contact head and the second contact head detect that the temperature of the vehicle battery is too high, the test assembly 7 is adjusted to return to its original position, and the shielding mechanism 6 is adjusted to shield and protect all the second channels 402 .

[0039] The placement mechanism 4 is provided to enclose and position the vehicle battery. The first movable box 312 and the second movable box 406 are provided to secure the vehicle battery. Furthermore, the second movable box 406 and the second contact head are provided, and a second rubber rod 409 on the exterior of the second movable box 406 contacts and secures one end of the vehicle battery.

[0040] The shielding mechanism 6 comprises: A second slider 601 is provided with a power system inside the second slider 601.

[0041] The power system in the second slider 601 is activated, centered within the fixed frame 5. The first telescopic rod 603 is activated, driving the fixed box 604 downward until it contacts the upper surface of the top plate 401. The second telescopic rod 606 is activated to a predetermined stroke, driving the telescopic plate 605 to gradually cover the second channel 402, providing shielding and protection for the vehicle battery.

[0042] By providing a shielding mechanism 6, the second channel 402 is shielded, thereby protecting the vehicle battery. Before testing, the top of the vehicle battery, except for the test position, is shielded and protected by adjusting the position of the two telescopic plates 605 and manually placing a blocking plate. During testing, if the first or second contact head detects that the battery temperature is higher than normal, the position of the two telescopic plates 605 is adjusted so that they contact each other, completely shielding the top of the second channel 402 and preventing the vehicle battery from exploding and injuring the user.

[0043] Working principle: Before using the device, turn on the control mechanism 3, which drives the placement mechanism 4 to move outside the body 1. Manually place the car battery in the control mechanism 3, and then adjust the placement mechanism 4 to fix the position of the car battery.

[0044] Before using the device, the power system in the first slider 302 is turned on, and the first slider 302 begins to move in the slide 301, thereby driving the contact component 303 and the placement mechanism 4 to move until the placement mechanism 4 is outside the body 1.

[0045] The first lifting rod 308 is activated, driving the placement mechanism 4 upward. The car battery is then manually placed on the bottom plate 306, so that the car battery aligns with the lug 307 on the side away from the first movable box 312. The placement mechanism 4 is adjusted to secure the car battery. The fourth push rod 405 is activated, driving the second movable box 406 and the second rubber rod 409 toward the car battery, pushing the car battery toward the support plate 403 until the car battery aligns with the support plate 403.

[0046] At the same time, the first push rod 311 is opened, and the first push rod 311 drives the first movable box 312 to move toward the car battery until the first rubber rod 315 outside the first movable box 312 contacts the car battery, so that the car battery and the ear plate 307 are more closely fitted.

[0047] The power system in the first slider 302 is adjusted so that the car battery enters the interior of the machine body 1 .

[0048] According to the position of the motor, the shielding mechanism 6 is adjusted to shield the untested area. Before the test, there is no blocking plate placed inside the second channel 402. According to the position of the car battery electrode, the test assembly 7 is adjusted so that the test head in the test assembly 7 is aligned with the second channel 402 and the electrode position. The shielding mechanism 6 is adjusted to shield the untested area. The power system in the second slider 601 is turned on, so that the second slider 601 is in the center position in the fixed frame 5. The first telescopic rod 603 is turned on. The first telescopic rod 603 drives the fixed box 604 to move downward until the fixed box 604 contacts the upper surface of the top plate 401. The second telescopic rod 606 is turned on to the corresponding stroke. The second telescopic rod 606 drives the telescopic plate 605 to move. The telescopic plate 605 gradually covers the second channel 402 to shield and protect the car battery.

[0049] For the second channel 402 that is outside the test position and is not protected by the shielding mechanism 6 , a blocking plate is manually installed in the corresponding second channel 402 .

[0050] Then, the power system in the test assembly 7 is turned on, so that the test head in the test assembly 7 contacts the battery electrodes, and the voltage and current of the battery are tested.

[0051] During the test, the first telescopic column 314 and the second telescopic column 408 are opened periodically, the first telescopic column 314 drives the first contact head to contact the car battery, and the second telescopic column 408 drives the second contact head to contact the car battery, so as to measure the temperature of the car battery in real time. When the temperature of the car battery is higher than the normal value, the test is stopped, the test component 7 is adjusted to return to its original position, the shielding mechanism 6 is adjusted, the two second telescopic rods 606 are opened to the maximum stroke, and the telescopic plate 605 is used to shield and protect all the second channels 402.

[0052] During the test, the second push rod 3031 is in the initial state, and the third push rod 3033 is opened to the second stroke. At this time, the third push rod 3033 drives the contact column 3034 to move into the groove 304, opens the cooling plate 305, and the temperature is gradually transferred to the heat-conducting rod outside the contact column 3034, and the temperature of the heat-conducting rod decreases.

[0053] After the test is completed, the placement mechanism 4 is adjusted again until it is outside the body 1, and the first lifting rod 308 is opened to place the assembly away from the bottom plate 306. At this time, the car battery is manually removed, and the contact assembly 303 is opened to clean and dissipate heat from the bottom plate 306. The contact assembly 303 is adjusted to promote cooling of the bottom plate 306.

[0054] After removing the car battery, adjust the third push rod 3033 to its initial position, driving the contact pin 3034 back to its original position. Then, activate the second push rod 3031 to its first stroke, driving the movable rod 3032, the third push rod 3033, and the contact pin 3034 to move above the bottom plate 306. Then, activate the third push rod 3033 to its first stroke, driving the contact pin 3034 downward, until the contact pin 3034 contacts the upper surface of the bottom plate 306. The second push rod 3031 is adjusted to reciprocate between the first and second strokes, causing the heat-conducting rod on the outside of the contact pin 3034 to drive impurities downward through the through slot 309. The heat-conducting rod then begins to transfer heat to the bottom plate 306, cooling it down.
