[0029] The following reference Figures 1 to 18 This application describes a housing assembly and a battery pack assembly according to some embodiments thereof.

[0030] Example 1 See Figures 1 to 18As shown, an embodiment of this application provides a housing assembly, including: a fixing frame 1, a housing 2, a positioning component 3, and a locking mechanism 4; wherein, the fixing frame 1 is used to fix it to a target location, and the fixing frame 1 forms an installation cavity 105 and an opening 106 arranged sequentially along a first preset direction a, and the housing 2 can slide with the fixing frame 1 so that the housing 2 can be pushed into the installation cavity 105 through the opening 106 along the first preset direction a; along the first preset direction a, the front end of the housing 2 is detachably connected to the front end of the fixing frame 1 through the positioning component 3, and the rear end of the housing 2 is detachably connected to the rear end of the fixing frame 1 through the locking mechanism 4.

[0031] It should be noted that the housing 2 provided in this application can be used as the housing 2 of a battery pack, and this will be used as an example in the following text. Of course, the housing 2 is not limited to being used as the housing 2 of a battery pack, but can also be used as the housing 2 of other products, depending on actual needs.

[0032] Based on the structure described above, the assembly and disassembly process of the housing assembly provided in this application is as follows: The assembly process is as follows: along the first preset direction a, push the box 2 into the mounting cavity 105 of the fixed frame 1 through the opening 106 on the fixed frame 1. After installation, quickly position the front end of the box 2 with the front end of the fixed frame 1 through the positioning component 3, and quickly connect the rear end of the box 2 with the rear end of the fixed frame 1 through the locking mechanism 4, thereby completing the assembly and fixation between the box 2 and the fixed frame 1. The operation is simple and convenient. The disassembly process is as follows: Simply unlock the locking mechanism quickly to disconnect the rear end of the box from the rear end of the fixing frame. Then, pull the box 2 out of the mounting cavity 105 of the fixing frame 1 in the opposite direction of the first preset direction a. The operation is simple and convenient.

[0033] As can be seen, the structure of the housing 2 and the fixing frame 1 has been redesigned in this application. The front end of both is positioned by a quick positioning component, and the rear end of both is quickly connected by a locking mechanism. The method of using a large number of bolts or glue for fixing is no longer used, which makes installation and disassembly more convenient, improves the efficiency of assembly and disassembly, makes maintenance easier, saves manpower, and will not damage the battery pack, thus helping to extend the service life of the battery pack.

[0034] Furthermore, preferably, the first preset direction a can be the length direction of the box body 2 and the fixing frame 1. Of course, it is not limited to this. The first preset direction a can also be the width direction of the box body 2 and the fixing frame 1, etc., depending on the actual needs.

[0035] Furthermore, preferably, the fixing frame 1 can be detachably connected to the target location via bolts or screws. Of course, it is not limited to this, and the connection method can be designed according to actual needs.

[0036] In this embodiment, preferably, as follows: Figures 7 to 12 As shown, the positioning component 3 includes a positioning member 31 and a positioning hole 32, one of which is disposed in the housing 2 and the other is disposed in the fixing frame 1, and the positioning member 31 is inserted into the positioning hole 32. This positioning structure makes it easier to assemble and position the housing 2 and the fixing frame 1. The locking mechanism 4 includes a rotating locking member 41, an auxiliary locking member 42, and a locking connecting member 43. One of the rotating locking member 41 and the auxiliary locking member 42 is disposed on the fixed frame 1, and the other is disposed on the housing 2. The auxiliary locking member 42 forms a limiting groove 421. The rotating locking member 41 is rotatably connected to the fixed frame 1 or the housing 2, and the rotating locking member 41 can rotate so that part of the structure rotates into the limiting groove 421. The locking connecting member 43 is detachably inserted into the rotating locking member 41 and the auxiliary locking member 42.

[0037] Based on the structure described above, the detailed assembly and disassembly process of the box assembly provided in this application is as follows: The assembly process is as follows: along the first preset direction a, the box 2 is pushed into the mounting cavity 105 of the fixing frame 1 through the through 106 on the fixing frame 1 until the positioning member 31 is inserted into the positioning hole 32, thereby completing the fixing and limiting of one end of the box 2. Then, the locking member 41 is rotated so that it can be locked in the limiting groove 421 of the auxiliary locking member 42. Finally, the locking connecting member 43 is inserted into the rotating locking member 41 and the auxiliary locking member 42 in sequence, thereby completing the assembly and fixing between the box 2 and the fixing frame 1. The operation is simple and convenient. The disassembly process is as follows: Simply pull the locking connecting component 43 out from the rotating locking component 41 and the auxiliary locking component 42, then rotate the rotating locking component 41 to move the rotating locking component 41 out from the limiting groove 421. Then, the box 2 can be pulled out from the mounting cavity 105 of the fixing frame 1 in the opposite direction of the first preset direction a. The operation is simple and convenient.

[0038] As can be seen, the structure of the housing 2 and the fixing frame 1 has been redesigned in this application. The front ends of the two adopt a plug-in connection, and the rear ends of the two adopt a rotating locking structure. The method of using a large number of bolts or glue to fix them is no longer used, which makes installation and disassembly more convenient, improves the efficiency of assembly and disassembly, makes maintenance easier, saves manpower, and will not damage the battery pack, thus helping to extend the service life of the battery pack.

[0039] Furthermore, preferably, the rotating locking member 41 is disposed on the housing 2, and the auxiliary locking member 42 is disposed on the fixed frame 1. Of course, it is not limited to this. The rotating locking member 41 can also be disposed on the fixed frame 1, and the auxiliary locking member 42 can be disposed on the housing 2, depending on the actual needs.

[0040] In this embodiment, preferably, as follows: Figures 7 to 12 As shown, the locking mechanism 4 also includes a support base 44 and a mounting shaft 45 connected thereto; wherein, the support base 44 is fixed to the fixing frame 1 or the housing 2 that cooperates with it; the rotating locking member 41 is rotatably sleeved on the mounting shaft 45. As can be seen from the structure described above, the support base 44 supports the mounting shaft 45, and the mounting shaft 45 supports the rotating locking member 41, thereby facilitating the rotation of the rotating locking member 41 relative to the mounting shaft 45.

[0041] Furthermore, preferably, the mounting shaft 45 and the support base 44 can be an integral structure. Of course, it is not limited to this; they can also be separate structures, connected together by welding or other processes.

[0042] In this embodiment, preferably, as follows: Figures 8 to 12 As shown, the locking mechanism 4 also includes a first limiting bushing 46, a second limiting bushing 47, a spring 48, a pressure ring 49, and a locking nut 410; wherein, the mounting shaft 45 includes a limiting shaft portion 451, a thick shaft portion 452, and a thin shaft portion 453 connected in sequence with their diameters decreasing sequentially, and the limiting shaft portion 451 is connected to the support base 44. It can be seen that the limiting shaft portion 451 has the largest diameter among the three, and the thin shaft portion 453 has the smallest diameter, and the three form a three-stage stepped shaft, and along the far The diameter of the components decreases sequentially from the support base 44; the rotating locking member 41 is rotatably connected to the thick shaft portion 452 of the mounting shaft 45 via the first limiting bushing 46 and the second limiting bushing 47, and the first limiting bushing 46 abuts against the end of the limiting shaft portion 451; both the first limiting bushing 46 and the second limiting bushing 47 form limiting flanges 411, and the rotating locking member 41 is disposed between the limiting flanges 411 of the first limiting bushing 46 and the second limiting bushing 47; The pressure ring 49 and the locking nut 410 are both sleeved on the outside of the thin shaft portion 453, and the pressure ring 49 abuts against the end of the thick shaft portion 452; the spring 48 is sleeved on the thick shaft portion 452 and abuts against the pressure ring 49 and the second limiting bushing 47; the locking nut 410 is threadedly connected to the thin shaft portion 453 and is used to press the pressure ring 49. As can be seen from the structure described above, the mounting shaft 45 in this application adopts a three-stage stepped shaft structure, which forms two limiting steps that can respectively limit the first limiting bushing 46 and the pressure ring 49 on both sides. The pressure ring 49 is fixed with a locking nut 410, thereby ensuring that the distance between the first limiting bushing 46 and the pressure ring 49 is within a suitable range for installing the second limiting bushing 47 and the spring 48. The compression degree of the spring 48 can be controlled, and the spring 48 always applies elastic force to the second limiting bushing 47, so that the limiting flange 411 of the second limiting bushing 47 and the limiting flange 411 of the first limiting bushing 46 can always be clamped on both sides of the rotating locking member 41. This allows the rotating locking member 41 to drive the first limiting bushing 46 and the second limiting bushing 47 to rotate relative to the mounting shaft 45, thereby reducing the friction during rotation, making rotation easier, and providing a certain feel during operation. It should be noted that the aforementioned first limiting bushing 46, second limiting bushing 47, spring 48, pressure ring 49, and locking nut 410 may be omitted. In other words, only the rotating locking member 41 needs to cooperate with the mounting shaft 45 on the support base 44. However, in this case, the rotating locking member 41 may detach from the mounting shaft 45 during vibration. Of course, this is not the only option. Alternatively, the mounting base may be omitted, and only a mounting shaft 45 can be provided, directly mounted on the housing 2. The rotating locking member 41 can then be rotatably fitted onto the mounting shaft 45, achieving a rotatable connection between the rotating locking member 41 and the housing 2. The specific choice depends on actual needs.

[0043] In this embodiment, preferably, as follows: Figure 8 and Figure 9 As shown, the rotating locking member 41 includes a sleeve portion 4101, a mating portion 4102, and a gripping portion 4103; wherein, the sleeve portion 4101 is rotatably sleeved on the mounting shaft 45; the mating portion 4102 and the gripping portion 4103 are both connected to the sleeve portion 4101, and the mating portion 4102 and the gripping portion 4103 are arranged in an L-shape; the mating portion 4102 can rotate into the limiting groove 421.

[0044] As can be seen from the structure described above, the grip part 4103 is easy for the operator's hand to hold and easy to rotate the locking member 41, while the mating part 4102 can cooperate with the limiting groove 421 to achieve limiting.

[0045] Furthermore, preferably, the sleeve portion 4101, the mating portion 4102, and the gripping portion 4103 can be an integral structure. Of course, it is not limited to this; they can also be separate structures connected by welding or other processes. Of course, it is not limited to this.

[0046] In this embodiment, preferably, as follows: Figure 13 , Figure 14 and Figure 18 As shown, the sidewalls of the rotating locking member 41 and the limiting groove 421 are both formed with insertion holes 412, and the locking connecting member 43 is sequentially inserted into the insertion holes 412 on the sidewalls of the rotating locking member 41 and the limiting groove 421. As can be seen from the structure described above, the locking connecting member 43, the rotating locking member 41, and the side wall of the limiting groove 421 are connected by a plug-in fit, which is simple, convenient, time-saving and labor-saving.

[0047] In this embodiment, preferably, as follows: Figure 15 and Figure 18 As shown, the locking connection member 43 includes a first limiting part 431, a plug-in part 432, and a second limiting part 434 connected in sequence; wherein, the plug-in part 432 is inserted into the plug hole 412 on the side wall of the rotating locking member 41 and the limiting groove 421, the first limiting part 431 abuts against the outer wall of one side of the limiting groove 421, and the second limiting part 434 abuts against the outer wall of the other side of the limiting groove 421. As can be seen from the structure described above, the insertion part 432 serves to connect the rotating locking member 41 with the side wall of the limiting groove 421 of the auxiliary locking member 42. The first limiting part 431 and the second limiting part 434 respectively serve to limit each other with the limiting groove 421, so that when the locking connecting member 43 is forcibly pulled out from the auxiliary locking member 42 without applying external force, the locking connecting member 43 is not easy to fall off the auxiliary locking member 42 in the working state.

[0048] Of course, the structure of the locking connection member 43 is not limited to this; it can also adopt other types of pin structures, depending on the actual needs.

[0049] Furthermore, preferably, a connecting part 433 may be provided between the insertion part 432 and the second limiting part 434, and the diameter of the connecting part 433 is smaller than that of the insertion part 432 and the second limiting part 434. Of course, this connecting part 433 may not be provided, depending on the actual needs.

[0050] Furthermore, preferably, the insertion part 432, the first limiting part 431, the connecting part 433 and the second limiting part 434 are an integral structure, but of course, it is not limited to this.

[0051] Furthermore, preferably, the auxiliary locking member 42 is formed with a relief groove 422 and is used to avoid the second limiting part 434.

[0052] In this embodiment, preferably, as follows: Figure 5 and Figure 7 As shown, the housing 2 and the fixing frame 1 are slidably connected by the first slide rail 5 and the second slide rail 6. As can be seen from the structure described above, the housing 2 and the fixing frame 1 are fitted with a first slide rail 5 and a second slide rail 6, which facilitates pushing the housing 2 into the mounting cavity 105 of the fixing frame 1, reduces friction, avoids jamming during the process of pushing the housing 2 into the mounting cavity 105 of the fixing frame 1, and reduces workload. Of course, it is not limited to this.

[0053] It should be noted that the housing 2 and the fixing frame 1 are not limited to using two slide rails for sliding cooperation. They can also use slide rails and sliders for sliding cooperation, or other structures for sliding cooperation, depending on the actual needs.

[0054] In this embodiment, preferably, as follows: Figure 4 As shown, the housing assembly also includes a handle 7, and the handle 7 is located at the rear end of the housing 2 along the first preset direction a. As can be seen from the structure described above, by holding the handle 7, it is easy to push the housing 2 into the mounting cavity 105 of the fixing frame 1 or pull the housing 2 out of the mounting cavity 105 of the fixing frame 1, which improves the convenience of operation and helps to improve maintenance efficiency. Of course, the handle 7 can also be omitted, depending on the actual needs. In this embodiment, preferably, as follows: Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, the housing assembly also includes a first connector 8 and a second connector 9; wherein, along the first preset direction a, the first connector 8 is disposed at the front end of the housing 2, and the second connector 9 is disposed at the front end of the fixing frame 1, and when the housing 2 is pushed into the mounting cavity 105 and in place, the first connector 8 and the second connector 9 are inserted together, and the second connector 9 forms an insertion interface exposed to the fixing frame 1. As can be seen from the structure described above, when the housing 2 is fully pushed into the mounting cavity 105 of the fixing frame 1, the first connector 8 at the front end of the housing 2 can be inserted into the second connector 9 at the front end of the fixing frame 1, thereby completing the electrical connection operation. Moreover, the second connector 9 on the fixing frame 1 also forms an exposed insertion interface, which facilitates the electrical connection between other electrical devices and the battery pack, improving the convenience of operation. In this embodiment, preferably, as follows: Figure 1 , Figure 3 and Figure 6 As shown, there are three positioning components 31 arranged in a triangle. Correspondingly, there are also three positioning holes 32, which correspond one-to-one with the three positioning components 31.

This structure is conducive to lightweight design, especially for aircraft design, and also helps the battery pack to dissipate heat.

[0061] Furthermore, preferably, the side plates 104 on both sides can be connected to the first frame 101 and the second frame 102 by welding or bolts, etc. Of course, it is not limited to this, and the specific connection can be made according to actual needs.

[0062] Furthermore, preferably, the first frame 101 and the second frame 102 can also be hollow square frame structures, which are lightweight and contribute to lightweight design.

[0063] Furthermore, preferably, each side of the first frame 101 can be a plate-like structure, but of course, it is not limited to this.

[0064] Furthermore, preferably, each side of the second frame 102 can be a hollow beam, but of course, it is not limited to this.

[0065] Furthermore, preferably, the first frame 101 is provided with flanges on opposite sides along the first preset direction a, so that the first frame 101 is U-shaped as a whole, and these flanges are attached to and connected to the side plate 104.

[0066] Furthermore, preferably, the side panel 104 has an internally hollow, triangular frame structure, which satisfies the function of limiting the side of the housing 2 while being lightweight, thus contributing to lightweight design. Of course, the shape of the side panel 104 is not limited to this.

[0067] Furthermore, preferably, the base plate 103 and the side plate 104 are an integral structure, which can be formed by bending, etc., but of course, it is not limited to this.
