[0040] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0041] Example 1

[0042] like Figures 1-5 As shown, the vehicle-mounted distributed battery pack rapid separation device comprises a vehicle chassis 9, a mounting groove 10 on the chassis 9, a housing 1 fixedly connected to the mounting groove 10, a battery pack 3 slidably disposed within the housing 1, a crossbeam 2 fixedly connected to and vertically limiting the battery pack 3 above the housing 1, a gate 4 rotatably disposed at the end of the housing 1 and limiting the horizontal and vertical directions of the battery pack 3, and a traction component fixedly connected to the battery pack 3. In case of emergencies such as fire, the operator can unlock the battery pack by pulling the gate. Under the traction of the traction component, the battery pack quickly slides out of the housing, achieving rapid separation from the main body of the device and effectively preventing the spread of fire.

[0043] In this embodiment, based on the structure and usage requirements of the vehicle chassis, the specific location of the mounting slot and the number of mounting slots and battery packs are determined. When multiple battery packs are involved, they are connected via quick-connect interfaces. To ensure a tighter connection between the housing and the mounting slot and prevent relative movement between the housing and the mounting slot when the battery pack slides within the housing, this embodiment fixes the housing to the mounting slot. Specifically, as shown... Figure 5 As shown, fastening bolts 17 are connected and installed on the bottom surface of the housing 1, and there are no less than 2 sets of fastening bolts, each set consisting of 2 bolts, which are respectively installed at the four corners of the bottom of the housing. The housing 1 is connected and fixed to the mounting groove 10 by fastening bolts 17.

[0044] In order to effectively prevent the up and down movement of the battery pack, the pressing plate is used to press the battery pack in this embodiment. Specifically, as shown in Figure 2 , the first pressing plate 7 is connected on one side of the cross beam 2. Both of the pressing plates are spring pressing plates with certain elasticity. After the battery pack is pushed into the shell, the first pressing plate 7 will automatically press the upper surface of one end of the battery pack 3. The second pressing plate 8 is connected on the inner wall of the shutter 4. The second pressing plate 8 and the upper surface of the other end of the battery pack 3 are connected by the elastic force of the second pressing plate 8.

[0045] Embodiment 2

[0046] In order to achieve the rapid movement of the battery pack under smaller traction force and improve the installation and disassembly speed between the battery pack and the shell, the roller is used in this embodiment. Specifically, as shown in Figure 5 , the roller 12 is connected on both sides of the inner surface of the shell 1. There are at least three rollers, which are respectively arranged at the tail end, the middle part and the front end of the shell. The battery pack 3 is connected with the shell 1 through the roller 12. The arrangement of the roller forms rolling friction between the battery pack and the shell. Compared with sliding friction, the contact area of rolling friction is small, which reduces the wear of the surface of the battery pack.

[0047] In order to enable the operator to quickly lift the shutter and release the limiting locking of the battery pack, the handle 13 is connected on the head of the shutter in this embodiment. Specifically, as shown in Figure 2 , Figure 5 , the handle 13 can prevent the hands from slipping during the operation of the shutter 4, and improve the efficiency of the quick separation of the battery pack.

[0048] In order to limit the rotation of the shutter, the pin and the pin hole are matched in this embodiment. Specifically, as shown in Figure 5 , the end of the shell 1 is provided with a slot 14. The slot wall of the slot 14 and the plate body of the shutter 4 are provided with coaxial pin holes 15. The pin 16 is inserted into the pin hole 15, so that the shutter can be effectively prevented from moving upward after being closed.

[0049] Embodiment 3

[0050] Different from the above embodiments, in order to facilitate the quick separation between the battery pack and the shell, and to save labor, the traction member is used in this embodiment. Specifically, the traction member is composed of the traction rope 5 and the traction ring 6. The traction rope 5 is a steel wire rope. One end of the traction rope 5 is connected with the battery pack 3, and the other end is connected with the traction ring 6. The traction ring and the traction rope are used to drag the battery pack.

[0051] In order to facilitate the storage and protection of the traction member, the wire box 11 is used in this embodiment to improve the efficiency. The wire box 11 is fixed between the installation grooves 10. As shown in Figure 4As shown, the traction ring 6 and the traction rope 5 can be neatly stored in the wire box 11 after winding, and the traction ring 6 and the traction rope 5 can be neatly stored in the wire box 11 after winding, which is beneficial to the storage and protection of the traction member and significantly improves the efficiency of using the traction member.
