It is an ideal shell for high-end instruments.

[0003] The existing battery aluminum shell has a complex structure, which is not convenient for installation and disassembly between the battery shell and the battery pack. At the same time, due to the lack of certain buffering measures during use, the battery pack cannot be clamped and fixed, resulting in looseness between the battery shell and the battery pack body, thereby causing collisions and poor buffering effects. The battery pack will be damaged due to bumps and vibrations generated during the vehicle operation, thereby reducing the service life of the battery pack and affecting the safety of the battery body during use. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a set-type aluminum shell for a new energy power battery, which can solve the problem that the battery pack cannot buffer and has a poor fixing effect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a set-type new energy power battery aluminum shell, comprising a shell and a shell cover, the shell cover is installed on one end of the shell by bolts, and a battery pack is arranged inside the shell;

[0006] The shell cover is fixedly connected with an anti-sway top block on one side close to the shell, and a buffer fixing mechanism is arranged inside the shell;

[0007] The provision of the anti-sway top block can effectively prevent the battery pack from swaying laterally inside the housing;

[0008] The buffer fixing mechanism is arranged in four groups, the structures of the four groups of buffer fixing mechanisms are interconnected, and are arranged in a cross shape inside the housing;

[0009] A thermal insulation layer for thermally insulating the battery pack is filled between the battery pack and the shell.

[0010] Preferably, the buffer fixing mechanism includes a limiting connection fixing block, which is fixedly connected to one side of the inner wall of the shell, and a buffer mounting groove extending to both sides of the limiting connection fixing block is opened on the side of the limiting connection fixing block away from the inner wall of the shell, and a mounting fixing plate is fixedly connected to one side of the battery pack group close to the buffer mounting groove, and a semicircular connecting slider is fixedly connected to one end of the mounting fixing plate.

[0011] Preferably, a buffer sliding hole is provided on the inner wall of the buffer installation groove, a buffer sliding rod is slidably connected inside the buffer sliding hole, a buffer fixing block is fixedly connected to one end of the buffer sliding rod, and a buffer limiting groove is provided on the installation fixing plate.

[0012] Preferably, the buffer fixing block and the limiting groove are both arc-shaped.

[0013] Preferably, a strong support spring is movably sleeved on the buffer slide rod, and two ends of the strong support spring are respectively fixedly connected to the surface of the buffer fixing block and the inner wall of the buffer mounting groove.

[0014] Preferably, a strong support spring is movably sleeved on the buffer slide rod, and two ends of the strong support spring are respectively fixedly connected to the surface of the buffer fixing block and the inner wall of the buffer mounting groove.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) In the aluminum shell of the set-type new energy power battery, when the battery pack is completely inserted into the interior of the shell, the buffer fixing block is inserted into the interior of the buffer limit groove. The battery pack can be fixed inside the shell by the elasticity of the strong support spring and the principle of relative action of force. The strong support spring is set, and the buffer fixing block and the buffer slide rod are used. Therefore, when the shell is subjected to external impact force, the friction between the buffer slide rod and the buffer slide hole and the elasticity of the strong support spring can effectively dissipate the impact force by friction, so that the shell has a good buffering effect, thereby improving the anti-seismic performance of the battery pack, thereby increasing its service life and reducing the cost expenditure caused by replacement and maintenance.

[0018] (2) In the aluminum shell of the set-type new energy power battery, when the limit connection fixing block moves toward the battery pack following the impact force of the shell, the rubber buffer block is affected by the limit connection fixing block and deforms, and contacts the inner wall of the built-in buffer groove. Therefore, the impact force is buffered and energy is consumed by the deformation ability and elasticity of the rubber buffer block, thereby minimizing the impact of vibration or external force on the battery pack.

[0019] (3) The thermal insulation layer of the aluminum shell of the set-type new energy power battery is expandable polystyrene, which has good insulation, thermal insulation and flame retardant properties. Therefore, it can prevent the battery pack from being affected by temperature and causing rapid aging and poor durability, thereby increasing the service life of the battery pack.

[0032] See also Figure 1-6 The utility model provides a technical solution: a set-type aluminum shell of a new energy power battery, comprising a shell 1 and a shell cover 2, the shell cover 2 is installed on one end of the shell 1 by bolts, a battery pack 3 is arranged inside the shell 1, an anti-sway top block 15 is fixedly connected on one side of the shell cover 2 close to the shell 1, and a buffer fixing mechanism is arranged inside the shell 1;

[0033] The anti-sway top block 15 can effectively prevent the battery pack 3 from swaying laterally inside the housing 1, thereby ensuring that it is stable after installation.

[0034] Further, the buffer fixing mechanism is provided in four groups, the structures of the four groups of buffer fixing mechanisms are all interconnected, and are arranged in a cross shape inside the shell 1, the buffer fixing mechanism includes a limit connection fixing block 5, the limit connection fixing block 5 is fixedly connected to one side of the inner wall of the shell 1, and a buffer installation groove 7 extending to both sides of the limit connection fixing block 5 is provided on the side of the limit connection fixing block 5 away from the inner wall of the shell 1, and a mounting fixing plate 6 is fixedly connected to one side of the battery pack group 3 close to the buffer installation groove 7, and a semicircular connecting slider 8 is fixedly connected to one end of the mounting fixing plate 6;

[0035] A buffer sliding hole 11 is provided on the inner wall of the buffer installation groove 7, a buffer sliding rod 16 is slidably connected inside the buffer sliding hole 11, a buffer fixing block 9 is fixedly connected to one end of the buffer sliding rod 16, a buffer limiting groove 12 is provided on the installation fixing plate 6, and both the buffer fixing block 9 and the buffer limiting groove 12 are arc-shaped;

[0036] Among them, a strong support spring 10 is movably sleeved on the buffer slide bar 16, and the two ends of the strong support spring 10 are respectively fixedly connected to the surface of the buffer fixing block 9 and the inner wall of the buffer installation groove 7;

[0037] When the battery pack 3 needs to be installed inside the shell 1, the installation fixing plate 6 is aligned with the buffer installation groove 7, and the battery pack 3 is pushed toward the inside of the shell 1. Since the connecting slider 8 is semicircular, the battery pack 3 is not blocked by the contact between the arc surface of the connecting slider 8 and the buffer fixing block 9, so that the battery pack 3 can enter the inside of the shell 1 more smoothly. When the battery pack 3 is completely entered into the inside of the shell 1, the buffer fixing block 9 is inserted into the inside of the buffer limit groove 12. The battery pack 3 can be fixed inside the shell 1 by the elasticity of the strong support spring 10 itself and the principle of relative action of force;

[0038] By providing the strong support spring 10, the buffer fixing block 9 and the buffer slide bar 16, when the shell 1 is subjected to external impact force, the friction between the buffer slide bar 16 and the buffer slide hole 11, and the elasticity of the strong support spring 10 itself can effectively dissipate the impact force by friction, so that the shell 1 has a good buffering effect, thereby improving the anti-seismic performance of the battery pack 3, thereby increasing its service life and reducing the cost expenditure caused by replacement and maintenance.

[0039] Furthermore, a built-in buffer groove 13 is opened on the inner wall of the buffer installation groove 7, and a rubber buffer block 14 is fixedly connected to the installation fixing plate 6, and the rubber buffer block 14 is movably connected to the inside of the built-in buffer groove 13;

[0040] The rubber buffer block 14 is made of rubber and has a honeycomb shape inside, so that it has better deformation ability, thereby ensuring its buffering effect;

[0041] When the limiting connection fixing block 5 moves toward the battery pack 3 following the impact force of the shell 1, the rubber buffer block 14 is deformed by the limiting connection fixing block 5 and contacts the inner wall of the built-in buffer groove 13. Therefore, the impact force is buffered and energy is consumed by the deformation ability and elasticity of the rubber buffer block 14, thereby minimizing the impact of vibration or external force on the battery pack 3.

[0042] Furthermore, a heat-insulating layer 4 is filled between the battery pack 3 and the housing 1;

[0043] The thermal insulation layer 4 is expandable polystyrene, which has good insulation, thermal insulation and flame retardant properties. Therefore, it can prevent the battery pack 3 from being affected by temperature and causing rapid aging and poor durability, thereby increasing the service life of the battery pack 3.

[0044] Working principle: When the battery pack 3 needs to be installed inside the shell 1, the installation fixing plate 6 is aligned with the buffer installation groove 7, and the battery pack 3 is pushed toward the inside of the shell 1. Since the connecting slider 8 is semicircular, the battery pack 3 is not blocked by the contact between the arc surface of the connecting slider 8 and the buffer fixing block 9, so that the battery pack 3 can enter the inside of the shell 1 more smoothly. When the battery pack 3 completely enters the inside of the shell 1, the buffer fixing block 9 is inserted into the inside of the buffer limit groove 12. Through the elasticity of the strong support spring 10 itself and the principle of relative action of force, the battery pack 3 can be fixed inside the shell 1;

[0045] By providing a strong support spring 10, a buffer fixing block 9 and a buffer slide rod 16, when the shell 1 is subjected to an external impact force, the friction between the buffer slide rod 16 and the buffer slide hole 11, and the elasticity of the strong support spring 10 itself can effectively dissipate the impact force through friction, thereby enabling the shell 1 to have a good buffering effect.
