[0028] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0029] Please refer to Figure 1-4 This utility model discloses a heat dissipation and vibration-resistant battery pack, which includes a middle frame 1, a battery module 2, a base plate 3, and an end cap 4. The battery module 2 is disposed inside the middle frame 1 and is fixed to the middle frame 1 by thermally conductive potting compound 5. Shock-absorbing components 6 are provided between the battery module 2 and the base plate 3 and between the battery module 2 and the end cap 4. A plurality of heat dissipation teeth 11 are provided on the outside of the middle frame 1.

[0030] The middle frame 1 encloses the battery module 2, which can improve the mechanical strength of the battery pack. Specifically, the middle frame 1 can be a hollow cuboid / cube with open ends, or a hollow cylinder with open ends, or other suitable shapes, such as... Figure 1-3 As shown, the middle frame 1 is a hollow cuboid with openings at both ends. It can be understood that the thermally conductive potting compound 5 is a high thermal conductivity potting compound 5, and the bottom and / or sides of the battery module 2 are fixed to the middle frame 1 by the thermally conductive potting compound 5. By fixing the battery module 2 to the middle frame 1 with the thermally conductive potting compound 5, fixation and vibration resistance can be achieved, and rapid heat dissipation can be achieved. The base plate 3 and end cap 4 are made of rigid plastic material, which has high strength, thus resisting external pressure and preventing damage to the battery module 2. In addition, the middle frame 1 is provided with several heat dissipation teeth 11. The heat dissipation teeth 11 can be set on all four sides of the outer surface of the middle frame 1, or on one or several sides. It can be understood that the extension direction of the heat dissipation teeth 11 on the middle frame 1 is the same as the direction of the forced cooling airflow. The setting of the heat dissipation teeth 11 can increase the heat dissipation area and form an airflow channel, achieving rapid cooling of the battery pack and improving the charging and discharging efficiency of the battery pack.

[0031] This utility model's heat dissipation and vibration-resistant battery pack uses a middle frame 1 to limit the battery module 2 and fills the space between them with thermally conductive potting compound 5. It also uses a base plate 3, shock absorber 6, and end cap 4 at both ends of the battery module 2 to achieve compression and fixation, thereby securing the battery module 2. The heat dissipation teeth 11 accelerate the heat dissipation of the battery pack, thus simplifying the structure and installation process of the battery pack, improving the performance of the battery pack, and extending the service life of the battery pack.

[0032] Furthermore, such as Figure 1 , 3 As shown, the battery pack also includes a waterproof and breathable valve 7, which is disposed on the end cover 4.

[0033] As the usage status of battery module 2 changes, the pressure in the battery pack will change. By setting a waterproof and breathable valve 7 on the end cover 4, the pressure inside and outside the battery pack can be balanced, and it can play a role in waterproofing and rapid pressure relief.

[0034] Furthermore, the filling height of the thermally conductive potting compound 5 is greater than or equal to 1 / 3 of the height of the battery module 2.

[0035] In the above technical solution, by setting the filling height of the thermally conductive potting compound 5 to be greater than or equal to 1 / 3 of the height of the battery module 2, efficient heat dissipation is achieved without adding too much weight.

[0036] Furthermore, such as Figure 3 As shown, the middle frame 1 is provided with a limiting device 12; the battery module 2 includes a battery 21 and an insulating protective plate 22. The battery 21 is provided with a limiting post 23 and a limiting baffle 24 that cooperate with the limiting device 12. The insulating protective plate 22 is located between the battery 21 and the middle frame 1.

[0037] Specifically, the limiting device 12 consists of several protruding strip-shaped portions, and the limiting post 23 shown in the figure has 6, but is not limited to this; the limiting baffle 24 is a sheet-like object protruding from the battery 21, and the limiting baffle 24 shown in the figure has 2, but is not limited to this; in the above technical solution, the limiting post 23 and the limiting baffle 24 can limit the longitudinal and lateral positions of the battery 21 in the middle frame 1, and the insulating protective plate 22 can provide insulation between the middle frame 1 and the battery 21.

[0038] Furthermore, such as Figure 1-3 As shown, the battery pack also includes a socket 8 and a wire 81. The end cover 4 has a wire hole (not shown in the figure). The wire 81 is electrically connected to the battery module 2 and the socket 8 and is led out from the wire hole.

[0039] In the above technical solution, the socket 8 and the wire 81 facilitate the connection between the battery pack and the charging unit.

[0040] Furthermore, such as Figure 1-3 As shown, both the base plate 3 and the end cap 4 are provided with a fixing bracket 9 on the side away from the battery module 2.

[0041] The mounting bracket 9 facilitates the installation and securing of the battery pack. In addition, the mounting bracket 9 can serve as a leverage point when moving the battery pack, making it easier to transport the battery pack.

[0042] Furthermore, such as Figure 2 As shown, a handle 10 is provided on the side of the base plate 3 away from the battery module 2.

[0043] The handle 10 makes it easy to lift the battery pack with one hand, facilitating its transportation.

[0044] Furthermore, the middle frame 1 is made of aluminum alloy, copper alloy or stainless steel; the base plate 3 and end cap 4 are made of rigid plastic; the shock absorber 6 is a shock absorber sheet or shock absorber block, and the shock absorber 6 is made of plastic or silicone.

[0045] In the above technical solutions, aluminum alloy, copper alloy, and stainless steel are commonly used metal materials. Using these materials for the middle frame 1 can meet the strength requirements and reduce costs. In addition, using rigid plastic materials for the base plate 3 and end caps 4 can meet the strength requirements; rubber and silicone are commonly used shock-absorbing materials. Using rubber or silicone materials for the shock-absorbing component 6 reduces costs.

[0046] On the other hand, this utility model provides a cleaning robot, which includes the aforementioned battery pack.

[0047] The cleaning robot of this invention, equipped with the aforementioned battery pack, can reduce its weight and enable rapid charging after cleaning in harsh working conditions, thereby extending its daily working time.
