[0001] This invention relates to the field of vehicle testing technology, and more specifically to a battery pack capacity tester. Background Technology

[0002] New energy vehicles are commonly referred to as electric vehicles. Their battery components are one of the most important components, providing power to the vehicle and energy for the normal operation of its internal components. When the battery components malfunction, it can cause harm to the vehicle and the people inside.

[0003] Application number CN202420465305.9 discloses a battery pack testing device, including a housing; a DC probe is provided at the head end of the housing for insertion into a vehicle's charging port; a testing circuit board is disposed inside the housing for testing the battery pack; and an insulation detection module is disposed on the testing circuit board for isolating leakage current. After the DC probe is inserted into the battery pack's interface, the battery pack can communicate with a sampling board. The sampling board feeds back the collected data to the electrically connected testing circuit board to detect faults in the battery pack. Simultaneously, an insulation detection module is also provided on the testing circuit board. In the event of dangerous situations such as leakage or short circuits, the insulation detection module can prevent damage to personnel or equipment due to leakage, or affect the use of the device.

[0004] The aforementioned battery pack testing equipment has the following problems when in use: due to the long charging time, the testing equipment needs to be connected to the vehicle's charging port for a long time. Due to gravity, the testing equipment and charging cable will pull down on the vehicle's charging port. Long-term use will affect the stability of the connection between the two, which will not only affect the test results but also affect normal charging. Summary of the Invention

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a battery pack capacity tester that effectively solves the problem that gravity can affect the stability of the connection between the test device and the charging port in existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a battery pack capacity tester, including a detector, a first connector and a second connector disposed on the detector, and further comprising: A connection angle adjustment assembly is used to adjust the connection angle between the first connector and the vehicle charging port. It includes a vertical plate rotatably mounted on one side of the detector, an adjustment plate fixedly mounted at the bottom of the vertical plate, a detection element on the detector for detecting the connection angle of the first connector, and an adjustment element at the rotatable connection of the vertical plate for adjusting the angle of the vertical plate. The reinforcement component includes a suction cup disposed outside the detector, wherein the internal pressure of the suction cup decreases when the detector is powered on; The first connector is equipped with a cleaning ring, which sprays airflow when the first connector is connected or disconnected.

[0007] Furthermore, the connection angle adjustment assembly also includes a second piston tube fixedly installed on the side wall of the detector, wherein a second piston rod is movably inserted into the side of the second piston tube away from the detector, and a second hinge is provided at the end of the second piston rod, and the vertical plate is rotatably installed on the second hinge.

[0008] Furthermore, the detection element includes two trigger switches disposed on the outer wall of the detection end, and the two trigger switches are respectively located directly above and directly below the first connector. The trigger switches are activated when squeezed, and are not activated when both trigger switches are squeezed simultaneously.

[0009] Furthermore, the adjusting component includes two right-angle rods fixedly mounted on the second piston rod, a rack slidably mounted between the two right-angle rods, a gear adapted to the rack fixedly sleeved on the rotating shaft of the second hinge, a third magnet mounted on each of the two right-angle rods, and two fourth magnets repelling the third magnets symmetrically mounted at both ends of the rack.

[0010] Furthermore, the reinforcement assembly also includes a positioning box fixedly installed on the outer wall of the detector, in which an air suction plate is slidably installed, and the suction cup is installed on the side of the positioning box away from the detector. When the detector is powered on, the air suction plate gradually moves away from the suction cup.

[0011] Furthermore, a first magnet is fixedly installed in the positioning box, and a second magnet that attracts the first magnet is fixedly installed on the suction plate.

[0012] Furthermore, the reinforcement assembly also includes a first piston tube mounted on the side wall of the detector, a first piston rod movably inserted at the end of the first piston tube away from the detector, a first hinge at the end of the first piston rod, a first pressure plate rotatably mounted on the first hinge, and a return spring sleeved on the first piston rod.

[0013] Furthermore, a first connecting pipe is connected between the first piston tube and the second piston tube. When the first piston rod moves into the first piston tube, the first piston tube draws air from the second piston tube, causing the second piston rod to slide out of the second piston tube.

[0014] Furthermore, a third connecting pipe is connected between the second piston tube and the positioning box. A baffle is slidably installed in the positioning box, and the baffle blocks the end of the third connecting pipe. When the suction plate slides, it pushes the baffle to be misaligned with the third connecting pipe.

[0015] Furthermore, the cleaning assembly also includes a second connecting pipe connecting the first piston tube and the cleaning ring. The cleaning ring is provided with multiple air outlets.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] The present invention will be further described below with reference to embodiments.

[0024] Example 1: refer to Figure 1A battery pack capacity tester includes a detector 1, a first connector 4 and a second connector 5 disposed on the detector 1. The detector 1 has a detection end 3 at its top, the first connector 4 is mounted on the detection end 3, and the second connector 5 is connected to a charging end 6, which is positioned on top of a support block 36. A handle 2 is fixedly mounted on the detector 1, and the outer wall of the handle 2 is covered with an insulating and anti-slip layer. The tester also includes a connection angle adjustment assembly for adjusting the connection angle between the first connector 4 and the vehicle charging port. This assembly includes a vertical plate 19 rotatably mounted on one side of the detector 1, an adjustment plate 20 fixedly mounted at the bottom of the vertical plate 19, a detection element on the detector 1 for detecting the connection angle of the first connector 4, and an adjustment element at the rotatable connection point of the vertical plate 19 for adjusting the angle of the vertical plate 19. The connection angle adjustment assembly also includes a second piston tube 16 fixedly mounted on the side wall of the detector 1, which is positioned away from the detection end. A second piston rod 17 is movably inserted into one side of the detector 1. A second hinge 18 is provided at the end of the second piston rod 17. The vertical plate 19 is rotatably mounted on the second hinge 18. The detection element includes two trigger switches 27 disposed on the outer wall of the detection end 3. The two trigger switches 27 are located directly above and directly below the first connector 4, respectively. The trigger switches 27 are activated when squeezed, and are not activated when both trigger switches 27 are squeezed simultaneously. The adjusting element includes two right-angle rods 22 fixedly mounted on the second piston rod 17. A rack 23 is slidably mounted between the two right-angle rods 22. A gear 24 adapted to the rack 23 is fixedly sleeved on the rotating shaft of the second hinge 18. A third magnet 25 is mounted on each of the two right-angle rods 22. Two fourth magnets 26 that repel the third magnets 25 are symmetrically mounted at both ends of the rack 23 (where the two trigger switches 27 control the two third magnets 25 or the two fourth magnets 26, respectively).

[0025] like Figure 1 As shown, the entire detector 1 is picked up by holding the handle 2 and connected to the charging port of the vehicle to be tested. During the insertion process, the two trigger switches 27 above and below the first connector 4 are in close contact with the outer wall of the vehicle charging port. Then the operator releases the handle and pulls out the support block 36 (pulling the telescopic rod 35 out of the storage hole 32) and connects the external charging terminal 6 to the second connector 5.

[0026] After installation, the entire detector 1 rests on the outer wall of the vehicle via the adjusting plate 20. When the detector 1 tilts, one of the two trigger switches 27 is pressed. When the entire detector 1 tilts downwards, the lower trigger switch 27 is pressed. Figure 3As shown, the third magnet 25 and the fourth magnet 26 located at the top repel each other, driving the rack 23 to move down. Through the transmission action of the rack 23 and the gear 24, the adjusting plate 20 is rotated, changing the connection angle of the detector 1. Similarly, when the angle of the detector 1 is too high, it is adjusted in the same way, thereby making the connection between the detector and the vehicle charging port more stable and improving the safety and stability of the detection.

[0027] Example 2: refer to Figure 1 and Figure 2 A reinforcement assembly is provided on the outside of the detector 1, including a suction cup 8 disposed on the outside of the detector 1. When the detector 1 is powered on, the internal pressure of the suction cup 8 decreases. The reinforcement assembly also includes a positioning box 7 fixedly installed on the outer wall of the detector 1. An air suction plate 9 is slidably installed in the positioning box 7. The suction cup 8 is installed on the side of the positioning box 7 away from the detector 1. When the detector 1 is powered on, the air suction plate 9 gradually moves away from the suction cup 8. A first magnet 10 is fixedly installed in the positioning box 7. A second magnet 11 attracted to the first magnet 10 is fixedly installed on the air suction plate 9. The reinforcement assembly also includes a first piston tube 12 installed on the side wall of the detector 1. A first piston is movably inserted into the end of the first piston tube 12 away from the detector 1. The first piston rod 13 has a first hinge 14 at its end, a first pressure plate 15 rotatably mounted on the first hinge 14, a return spring sleeved on the first piston rod 13, a first connecting pipe 21 connecting the first piston tube 12 and the second piston tube 16, when the first piston rod 13 moves into the first piston tube 12, the first piston tube 12 draws air from the second piston tube 16, driving the second piston rod 17 to slide out of the second piston tube 16, a third connecting pipe 31 connecting the second piston tube 16 and the positioning box 7, a baffle slidably mounted in the positioning box 7, the baffle blocking the end of the third connecting pipe 31, and the suction plate 9 pushing the baffle and the third connecting pipe 31 out of alignment when the suction plate 9 slides.

[0028] To improve the stability of the connection, a suction cup 8 is provided on the side wall of the detector 1. When the detector 1 is working, an attractive force is generated between the first magnet 10 and the second magnet 11. The second magnet 11 drives the air suction plate 9 to slide towards the first magnet 10, which reduces the air pressure inside the suction cup 8, thereby adsorbing the detector 1 to the outside of the vehicle.

[0029] In addition, when the detector 1 is inserted and connected, the first pressure plate 15 on the side is squeezed, the first piston rod 13 enters the first piston tube 12, the first piston tube 12 draws air from the second piston tube 16 through the first connecting pipe 21, causing the second piston rod 17 to move out of the second piston tube 16, increasing the strength of the adjusting plate 20 on the outside of the vehicle, improving the overall stability of the detector 1, and also ensuring the stability of the above-mentioned adjustment process.

[0030] Secondly, as the suction plate 9 slides, it will push open the baffle, causing the third connecting pipe 31 to open, thereby reducing the air pressure in the suction cup 8 again and further improving the adsorption capacity.

[0031] Example 3: The first connector 4 is provided with a cleaning ring 28. When the first connector 4 is connected and disconnected, the cleaning ring 28 will spray air. The cleaning assembly also includes a second connecting pipe 30 connecting the first piston tube 12 and the cleaning ring 28. The cleaning ring 28 is provided with multiple air outlets 29. When the first piston rod 13 moves into the first piston tube 12, the air in the first piston tube 12 enters the cleaning ring 28. The detector 1 has a receiving hole 32 on its side wall near the second connector 5. A telescopic rod 35 is movably inserted into the receiving hole 32. The support block 36 is installed at one end of the telescopic rod 35. An elastic cleaning airbag 33 is provided between the other end of the telescopic rod 35 and the inner wall of the receiving hole 32. A fourth connecting pipe is connected between the cleaning airbag 33 and the cleaning ring 28, and an air inlet pipe 34 is externally connected to the cleaning airbag 33.

[0032] During the adsorption process described above, the first piston rod 13 slides into the first piston tube 12, causing the air in the other half of the first piston tube 12 to be transported to the cleaning ring 28 through the second connecting pipe 30, where an airflow is ejected to clean the connection point before connection. After the test is completed, the charging terminal 6 is disconnected, and the support block 36 is pushed towards the detector 1. At this time, the telescopic rod 35 squeezes the cleaning airbag 33, transporting the air inside back to the cleaning ring 28 for another cleaning.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
