DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0037] Figure 2-4 As shown, the utility model provides a battery pack disassembly and assembly structure, which can be installed in various types of drones, and specifically includes a sliding frame 1, a base frame 4, and a locking assembly 5. The base frame 4 includes a set of symmetrical guide bars 41, and a slideway 411 is preset on the guide bar 41. The two slideways 411 are used to clamp and slide the sliding frame 1. The sliding frame 1 is used to fix and install the battery module, and the locking assembly 5 is also installed on the sliding frame 1. The locking assembly 5 keeps the sliding frame 1 and the base frame 4 relatively fixed, thereby realizing the fixed installation of the battery module.

[0038] In addition, the base frame 4 further includes reinforcing bars 42 connected between the guide bars 41 , and a plurality of reinforcing bars 42 are installed at intervals between the guide bars 41 . The strength and stability of the base frame 4 can be effectively improved by the reinforcing bars 42 .

[0039] The sliding frame 1 mentioned above specifically also includes a sliding member 3 and a limiting member 2, wherein the sliding member 3 is a plate-like structure, and a limiting piece 21 extends on both sides of the width of the sliding member 3. At the same time, a bayonet 412 is preset on the upper side of the guide strip 41, and the bayonet 412 can allow the limiting piece 21 to enter the slide 411, so that the limiting piece 21 can slide from top to bottom through the bayonet 412 and be embedded in the slide 411, thereby limiting the movement of the sliding member 3 in the vertical direction.

[0040] In addition, a limiting opening 211 is provided on the limiting plate 21. A strap 212 is passed through the two limiting openings 211 in sequence. After the battery is placed on the sliding member 3, the battery is fixed to the sliding member 3 by the strap 212, thereby achieving relative fixation between the battery and the sliding member 3.

[0041] like Figure 7 As shown, in order to limit the movement of the sliding member 3 in the slideway 411, a locking assembly 5 is also installed on the sliding member 3. The locking assembly 5 is composed of a fixed block 51 and a latch 52 from top to bottom. The fixed block 51 is respectively an upper half block and a lower half block. A groove 1 is provided in the upper half block, and a groove 2 is provided in the lower half block. The groove 1 is coaxial with the groove 2 and the diameter of the groove 1 is smaller than that of the groove 2. The groove 1 and the groove 2 constitute a limiting slide 511. The latch 52 can be slidably inserted in the limiting slide 511, wherein the part of the latch 52 located in the groove 2 is coaxially preset with a retaining ring 521, and a fixing ring 512 for blocking the retaining ring 521 is formed on the lower side of the upper half block. At the same time, a thrust spring 53 is set on the latch 52, and the thrust spring 53 is located between the fixing ring 512 and the retaining ring 521.

[0042] When the thrust spring 53 is in a natural state, the elastic force of the thrust spring 53 causes the lower end of the latch 52 to be embedded in the bottom frame 4, thereby limiting the movement of the sliding frame 1 and the battery on the sliding frame 1;

[0043] When the latch 52 is pulled out, the thrust spring 53 is compressed, and the latch 52 is separated from the base frame 4 , thereby unlocking the movement of the sliding frame 1 , and realizing the movement and disassembly of the sliding frame 1 on the base frame 4 . Embodiment 2

[0044] like Figure 5-6 As shown, the difference from the first embodiment is that the structures of the sliding frame 1 and the locking assembly 5 are as follows:

[0045] The limiting part 2 in the sliding frame 1 is the power frame 22, and the sliding part 3 is the bottom plate 31 of the power frame 22. Compared with the sliding frame 1 in the first embodiment, the sliding frame 1 in the second embodiment can store batteries more stably. A removable sealing cover 222 is provided at one or both ends in the length direction of the power frame 22 to facilitate the removal and placement of the battery.

[0046] In addition, heat dissipation holes 221 are provided around the power supply housing and on the sealing cover 222 , and the heat dissipation holes 221 are used to ensure the heat dissipation during the operation of the battery, thereby ensuring the normal operation of the battery.

[0047] In addition, a groove 311 is preset on the bottom plate 31 of the power frame 22, and the locking assembly 5 also includes a connecting plate 32 that cooperates with the groove 311. Therefore, the power frame 22 shell is made of a lighter material, and the connecting plate 32 is made of a stronger material. The fixing block 51 and the latch 52 in the locking assembly 5 are installed on the connecting plate 32 to improve the installation stability of the locking assembly 5, thereby ensuring the reliability of the locking sliding frame 1. Embodiment 3

[0048] like Figure 1 As shown, the rescue boat includes a shell 61 and a power assembly 7. The battery needs to be detachably installed in the shell 61. When the rescue boat is actually used, continuous operation is often required. By disassembling and replacing the battery, the purpose of rapid and continuous rescue operations can be achieved.

[0049] The housing 6 specifically includes a main housing 61 and a cover 62. A disassembly opening 611 is preset in the middle of the upper side of the main housing 61, and the disassembly opening 611 is sealed by the cover 62. In addition, the base frame 4 in the battery pack disassembly structure mentioned above is fixedly installed in the main housing 61, and the sliding frame 1 is disassembled and assembled on the base frame 4 through the disassembly opening 611.

[0050] The working principle of the utility model is:

[0051] When the battery needs to be replaced, open the cover 62, unlock the lock of the sliding frame 1, remove the sliding frame 1 from the base frame 4 and take it out from the disassembly and assembly port 611, and then install the sliding frame 1 loaded with fully charged batteries on the base frame 4, so that the rescue boat can be quickly recharged for rescue, which greatly improves the rescue efficiency.

[0052] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
