[0002] A battery pack is a battery that connects the cells to a PCM board and has functions such as charge and discharge control. A pack is a collection of several batteries. In new energy vehicles, battery packs are generally used to supply power to the vehicle. However, when a vehicle is in motion, it will experience slight vibrations, especially on bumpy roads, which can cause significant vibrations. This will also cause the battery pack to vibrate. Since there are many electronic components inside the battery pack, these vibrations may cause the connections of the electronic components to loosen, thus affecting the normal use of the battery pack.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a buffer box cover structure for a pack box, including a box body 1, an insulated box cover 2 sleeved on the top of the box body 1, a cross plate 4 fixedly connected to the inner cavity of the box body 1, soft pads 5 fixedly connected to the top of the cross plate 4 and the bottom of the insulated box cover 2, a spring assembly 6 fixedly connected between the two soft pads 5, and a heat dissipation water bladder 1 9 and a heat dissipation water bladder 2 10 fixedly connected to the bottom of the insulated box cover 2, the inner cavities of the heat dissipation water bladder 1 9 and the heat dissipation water bladder 2 10 are filled with cooling water;

[0023] The insulated box cover 2 is fitted onto the top of the box body 1. Then, through the setting of the spring assembly 6, when shaking occurs, the elasticity of the spring assembly 6 absorbs the shaking of the box body 1. Then, through the setting of the first heat dissipation water bladder 9 and the second heat dissipation water bladder 10, the first heat dissipation water bladder 9 and the second heat dissipation water bladder 10 come into contact with the battery, thereby providing shock absorption and cushioning for the battery. Thus, through the setting of the soft pad 5, the first heat dissipation water bladder 9 and the second heat dissipation water bladder 10, the box body 1 and the battery are cushioned and shock-absorbing.

[0024] Among them, the first heat dissipation water bladder 9 and the second heat dissipation water bladder 10 are fixedly connected by the connecting pipe 11. There are two heat dissipation water bladders 9, which are located on the left and right sides above the box body 1.

[0025] By connecting the cooling water output end of the liquid cooling equipment to the transfer pump 12 and the input end to the transfer pump 27, the transfer pump 12 is started to deliver cooling water to the inner cavity of the heat dissipation water tank 9, and then to the inner cavity of the heat dissipation water tank 20 through the connecting pipe 11. During daily use, the cooling water inside the heat dissipation water tank 9 and the heat dissipation water tank 20 absorbs the heat of the battery, and the cooling water is discharged through the transfer pump 27, thereby completing the heat dissipation of the battery. The heat dissipation water tank 9 and the heat dissipation water tank 20 can also protect and buffer the battery.

[0026] Among them, the bottom end of the insulated box cover 2 is fixedly connected to the side plate 16, and the inner cavity of both the insulated box cover 2 and the side plate 16 is a vacuum cavity.

[0027] By setting the insulated box cover 2 and the side panel 16, the battery inside the box 1 is insulated from the top of the box 1, thereby preventing the heat from being dissipated from the box 1 in low temperature environments.

[0028] Among them, the inner cavity of the insulated box cover 2 is fixedly connected to a support plate 15, which is in the shape of an "eight".

[0029] The support plate 15 inside the insulated box cover 2 increases the overall strength of the insulated box cover 2, preventing the top of the insulated box cover 2 from being damaged due to excessive pressure.

[0030] Among them, the spring assembly 6 consists of a damping telescopic rod and a spring, with the damping telescopic rod located at the center of the spring cavity;

[0031] By using springs, the elasticity of the springs can dampen the shock between the box body 1 and the insulated box cover 2. The damping telescopic rods are used to position and guide the springs, thus preventing them from shifting during deformation.

[0032] Among them, the outer side of the box 1 is provided with a movable groove 3, and the side plate 16 is movably sleeved in the inner cavity of the movable groove 3;

[0033] The movable groove 3 allows for the positioning and guidance of the side panel 16, thereby improving the stability of the connection between the box body 1 and the insulated box cover 2.

[0034] Among them, the bottom ends of the first heat dissipation water bladder 9 and the second heat dissipation water bladder 10 are both fixedly connected to the telescopic tube 13, and the bottom of the telescopic tube 13 is fixedly connected to the control valve 14.

[0035] By setting the control valve 14, when thermal runaway occurs, the control valve 14 is activated to quickly discharge the cooling water inside the cavities of the first and second heat dissipation water bladders 9 and 10, thereby preventing the cooling water from being poured onto the battery and causing the thermal runaway of the battery to become more severe.

[0036] Among them, the inner cavity of the box 1 is fixedly connected to the baffle 7, the cross plate 4 and the baffle 7 are provided with a placement cavity 8, and the top of the telescopic tube 13 is fixedly connected to the inner cavity of the baffle 7.

[0037] The telescopic tube 13 is supported by the baffle 7 inside the housing 1, and the battery pack can be placed inside the placement cavity 8.

[0038] The working principle and usage process of this utility model are as follows: The battery is placed in the inner cavity of the placement cavity 8, and the insulated box cover 2 is sleeved with the outer side of the box body 1 through the movable groove 3.

[0039] During use, the output end of the vehicle's liquid cooling equipment is connected to the first delivery pump 12, and the input end is connected to the second delivery pump 17. Then, the first delivery pump 12 delivers cooling water to the inner cavity of the first radiator 9, and delivers it to the inner cavity of the second radiator 10 through the connecting pipe 11. The first and second radiators 9 and 10 come into contact with the battery, thereby absorbing and dissipating the heat generated by the battery.

[0040] When shaking occurs, the elasticity of the spring assembly 6 cushions the box 1, and the padding 5 prevents damage to the cross plate 4 and the insulated box lid 2.

[0041] In low-temperature environments, the batteries inside the placement chamber 8 are kept warm through the vacuum chambers of the inner cavity of the insulated box cover 2 and the inner cavity of the side plate 16, and the structural strength of the insulated box cover 2 is improved through the support plate 15.

[0042] When the battery experiences thermal runaway, the control valve 14 is activated to quickly drain the cooling water from the inner cavities of the first and second cooling water bladders 9 and 10, preventing the cooling water from contacting the battery.
