[0026] The principles and features of the present invention are described below in conjunction with all the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] The embodiment of the utility model discloses a battery assembly and a battery installation structure.

[0028] Reference Figure 1-Figure 7 A battery assembly includes a battery body 1, a battery terminal electrical connector 17 is provided on one end of the battery body 1, and a slider 2 is provided on the side of the battery body 1. There are two sliders 2, one on each side of the battery body 1, and both ends of each slider 2 are provided with a chamfer 4, such as Figure 1 and Figure 2 As shown, when the battery body 1 is inserted into the battery frame, the chamfered corners 4 can facilitate the insertion of the battery body 1 and provide convenience for the insertion of the battery body 1.

[0029] The battery body 1 is also provided with a flow channel for cooling and dissipating the heat of the battery body 1. The battery body 1 is provided with a heat dissipation interface, which is connected to the flow channel and is connected to a battery end water connector 18. Figure 1 As shown, the heat dissipation fluid is introduced into the heat dissipation interface through the battery end water connector 18. The temperature of the battery body 1 increases after long-term use. The heat dissipation fluid can cool the battery body 1 and increase the service life of the battery body 1.

[0030] The heat dissipation interface and the battery end electrical connector 17 are located at the same end of the battery body 1, which can be better operated, such as Figure 7 As shown. The heat dissipation interface is connected to the battery end water connector 18, and the heat dissipation interface is docked with the battery end water connector to facilitate cooling the inside of the battery body 1. The battery frame is provided with a vehicle end water connector 16 that is compatible with the battery end water connector 18. Because the battery frame needs to be installed on a new energy vehicle, it is called a vehicle end electrical connector 15 and a vehicle end water connector 16. Figure 7 shown.

[0031] The present invention also discloses a battery mounting structure, including a battery frame and a battery assembly, wherein the battery assembly is inserted into the battery frame. The battery frame is installed between the front wheel and the rear wheel of the new energy vehicle chassis. The battery frame includes a frame body 7. The inner wall of the opposite side of the frame body 7 is provided with a slide groove 8 adapted to the slider 2. Figure 4 and Figure 5 As shown, one end of the frame body 7 is open, and a sheath 12 is provided on the open end. After the battery frame is installed, the open end is located on one side of the new energy vehicle chassis, which facilitates the sliding of the battery body 1 and enables side replacement of the battery body 1. In this embodiment, when sliders 2 are provided on both sides of the battery body 1, the two ends of the sliders 2 are provided with chamfered corners 4. A sliding groove 8 is provided on the inner wall of the opposite side of the frame body 7 to facilitate guiding and limiting the battery body 1 when inserting it into the frame body 7. The provision of the chamfered corners 4 can further improve the convenience of insertion. The battery frame is provided with a vehicle-end electrical connector 15 that is compatible with the battery-end electrical connector 17.

[0032] The battery-side electrical connector 17 is compatible with and plugs into the vehicle-side electrical connector 15. Since the battery frame is fixed to the bottom of the new energy vehicle, it is called the vehicle-side electrical connector 15, and the corresponding one installed on the battery body is called the battery-side electrical connector 17. Similarly, the battery-side water connector 18 is compatible with and plugs into the vehicle-side water connector 16.

[0033] Reference Figure 1-Figure 7 One end of the battery frame is a closed end, and an end sealing plate is provided at the closed end. A fixing device is provided on the outside of the end sealing plate, and the fixing device positions the battery body 1 in the battery frame. Furthermore, the fixing device includes a fixing frame 11 located outside the end sealing plate and a fixing member located inside the fixing frame 11. In this embodiment, the fixing member is an electrically controlled permanent magnet 9. A ferromagnetic structure 10 is provided at the end of the battery body 1, as shown in FIG. Figure 1 As shown, it is used to cooperate with the electric-controlled permanent magnet 9. At least two electric-controlled permanent magnets 9 are provided. When two electric-controlled permanent magnets 9 are provided, the two electric-controlled permanent magnets 9 are respectively located on both sides of the closed end of the battery frame.

[0034] After the battery body 1 is inserted into the frame body 7, the position of the battery body 1 is fixed by the adsorption of the electric-controlled permanent magnet 9 and the ferromagnetic structure 10. The provision of two electric-controlled permanent magnets 9 can further improve the magnetic attraction effect. When the battery body 1 needs to be replaced, the electric-controlled permanent magnet 9 is energized. After the electric-controlled permanent magnet 9 is energized, it is demagnetized and the battery body 1 can be separated from the electric-controlled permanent magnet 9, making it convenient for the operator to pull the battery body 1 out of the frame body 7 for replacement with other batteries.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
