Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts maintenance, and more specifically, to a vehicle charging and discharging maintenance support device. Background Art

[0002] Power batteries are the core components of new energy vehicles and an important direction for future energy transformation. Power batteries are the power source for tools, mostly referring to batteries that provide power for electric vehicles, electric trains, electric bicycles, and golf carts. Power batteries are the core components of electric vehicles, and their cost accounts for 35%-50% of the cost of electric vehicles. Electric vehicle power batteries on the market can be divided into four categories: ternary materials, lithium iron phosphate, lithium manganese oxide, and others.

[0003] In actual situations, after a power battery has been used for a period of time, due to the characteristics of the battery, maintenance personnel are required to maintain, inspect and repair the battery in order to extend the service life of the power battery. Discharging the power battery is an especially important part of the power battery maintenance process. The existing power battery discharge operation generally uses charging and discharging equipment, and the existing charging and discharging equipment will have the following problems when in use; With the existing charging and discharging equipment, the staff first places the power battery of the automobile parts on the workbench, and the workbench only has a supporting function and cannot effectively assist the staff to connect the charging and discharging equipment with the power battery. The connection between the charging and discharging equipment and the power battery is as follows: the staff needs to connect the two ends of the positive and negative wires to the battery and the equipment respectively, and also needs to clamp one end of the detection wire on the battery connector. It is particularly important to note that the number of detection wires is generally 8-10, and multiple detection wires not only make the staff's preparation work cumbersome, but also the staff is prone to inaccurate operation, which leads to one end of the detection wire being unable to be firmly connected to the battery connector.

It is particularly noted that the power battery is composed of a plurality of power battery modules, rather than a whole power battery. During the detection process, the staff can place a single module in the equipment for detection to ensure the accuracy of the detection; Reference Figure 2 , Figure 3 and Figure 4 The support member 3 includes a movable bottom plate 31 fixedly connected to the lower end of the bracket 1, and a plurality of locking universal wheels capable of moving the device are installed at the lower end of the movable bottom plate 31 to ensure that the staff can move the device more conveniently, thereby facilitating the staff's carrying and placement work, reducing the staff's work content, and indirectly improving the practicability of the device; Reference Figure 2 , Figure 3 and Figure 4 , a movable carrying plate 32 is provided at the upper end of the movable bottom plate 31, and a handle is installed on the side wall of the carrying plate 32, which further facilitates the staff to move the carrying plate 32, wherein the carrying plate 32 can place a power battery so that the power battery can enter the bracket 1, and the more specific connection structure between the carrying plate 32 and the movable bottom plate 31 is: two damping grooves 33 are provided on the upper end surface of the movable bottom plate 31, and the two damping grooves 33 are slidably connected with a damping slider 34 connected to the carrying plate 32, so that when the damping slider 34 moves in the damping groove 33, the carrying plate 32 can be moved above the movable bottom plate 31, so that the power battery can enter the bracket 1 or move out of the bracket 1; Reference Figure 3 and Figure 4The lower end surface of the load-bearing plate 32 is fixedly connected with a plurality of support balls 35 connected to the movable base plate 31.

More specifically, the coolant 362 enters the collecting column 363 through the pipeline, and at this time the spring expansion seat 364 is squeezed and pushed by the coolant 362, so that the spring expansion seat 364 can shrink, so that the power battery can be sunk into the carrying bag 361. When the power battery is sunk into the carrying bag 361, the position where the carrying bag 361 is pressurized and the area where it is not pressurized will form a concave shape, so that the carrying bag 361 can limit the power battery, further ensuring the stability of the power battery.

It is also worth noting that when the battery module starts to discharge, with the assistance of the heat-conducting copper rod 365, the heat-conducting copper plate 366 and the coolant 362, the heat on the power battery can be transferred to the coolant, thereby achieving the purpose of reducing the heat of the power battery and further protecting the power battery. After the battery module is placed, the staff can push the supporting plate 32 into the bracket 1.

[0030] It should be noted that when the staff pushes the carrier plate 32, the staff can bend the guide plate 43 upwards to prevent the guide plate 43 from affecting the power battery from entering the bracket 1. After the power battery enters the bracket 1, the staff can rotate the rotating disk 431 according to the positive and negative poles of the power battery. When the rotating disk 431 rotates, the rotating shaft 42 can be rotated, and the horizontal angle of the guide plate 43 and the conductive member 44 can be further changed. Then the staff can move the position of the conductive member 44 on the guide plate 43, so that the conductive member 44 can be located above the position of the positive and negative poles of the power battery. Then the staff loosens the guide plate 43, and with the assistance of the coil spring in the reset ring 434, the conductive ball 444 in the conductive member 44 can contact the positive and negative poles of the power battery. It is particularly noted that the method of connecting the device to the negative pole of the power battery is consistent with the above method, so it is not repeated here. The staff can also insert the other end of the wire 45 into the charging and discharging device 2. When the charging and discharging device 2 is working, since the conductive ball 444, the conductive seat 443, the guide plate 43 and the wire 45 are all made of conductive materials, the normal operation of the charging and discharging device 2 can be guaranteed. It is particularly noteworthy that when the conductive ball 444 generates a certain amount of heat, the fluorinated liquid in the storage cavity 445 can enter the sponge block 447 through the capillary 446, so that the fluorinated liquid and the conductive ball 444 can contact each other, thereby achieving the purpose of cooling and protecting the conductive ball 444, and indirectly extending the service life of the device.

[0031] Then the staff can refer to the indicator strip 55 to compare the specifications of different types of power batteries, so that the staff can move the moving handle 537. With the assistance of the first strip opening 535 and the second strip opening 536, the position of the moving conductive block 534 can be moved accordingly, so that the moving conductive block 534 can be moved to a suitable position. When the moving conductive block 534 moves to a suitable position, the staff can start the electromagnetic block 5311. When the electromagnetic block 5311 works, the magnetic plate 5312 can be moved, and the mounting seat 5313 can be further moved, so that the contact ball 5314 can contact the terminal of the power battery, further ensuring the efficiency of detection and maintenance, thereby ensuring the normal use of the device. After the discharge is completed, the staff turns off the electromagnetic block 5311, and with the assistance of the spring 5315, the mounting seat 5313 and the contact ball 5314 can be reset, further ensuring the normal use of the device.
