Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

A battery bin 2 is fixedly connected to the lower surface of a pedal 1 of the electric scooter as shown in fig. 1, a battery substrate 3 and a circuit board 4 are arranged in the battery bin 2, a battery assembly is mounted on the upper surface of the battery substrate 3 and used for supplying power to the scooter, and electronic elements such as a CPU (Central processing Unit) and the like are mounted on the upper surface of the circuit board 4 and used for electrical control of the scooter.

As shown in fig. 2, the battery compartment 5 and the control compartment 6 are separated into the housing 14 of the battery compartment 2, the battery substrate 3 is correspondingly installed in the battery compartment 5, the circuit board 4 is correspondingly installed in the control compartment 6, the bottom surfaces of the battery substrate 3 and the circuit board 4 are both fixed with heat conducting columns 7, the heat radiating base 8 is installed in the battery compartment 5 and the control compartment 6 corresponding to the heat conducting columns 7, and the other end of the heat conducting columns 7 is connected with a heat radiating structure. As shown in fig. 3, the heat dissipation structure includes a heat dissipation base 8 mounted on a housing 14 of the battery compartment 2, where the heat dissipation base 8 is flat, i.e. has a large bottom area and a small height, so as to ensure that the height of the heat dissipation structure is small, and the thickness of the battery compartment 2 is not significantly increased, thereby not reducing the obstacle crossing performance of the scooter.

As shown in fig. 4, the top of the heat dissipation base 8 is open, an adsorption/desorption bed 9 is arranged in the heat dissipation base 8, and the adsorption/desorption bed 9 wraps the energy storage core 10. The adsorption/desorption bed 9 is made of a material having thermal conductivity and water absorption, such as graphite, and when the temperature of the graphite is raised by thermal conductivity, the surface area of the graphite increases to absorb the surrounding moisture. While a decrease in surface area releases moisture after a decrease in temperature. The energy storage core 10 is composed of a metal salt aqueous complex. The metal salt aqueous complex may be sodium sulfate decahydrate, magnesium sulfate heptahydrate, disodium hydrogen phosphate dodecahydrate, sodium thiosulfate pentahydrate, calcium chloride hexahydrate or lithium nitrate trihydrate. The energy storage core 10 also includes a support matrix to which the metal salt water complex is immobilized. The supporting framework is made of metal foam, metal wire mesh, graphite fiber or porous heat-conducting ceramic. By utilizing the thermal dehydration mechanism of the metal salt water complex, when the metal salt water complex absorbs heat, the decomplexed crystal water is further absorbed by the adsorption and desorption bed 9, and when the dehydrated metal salt water complex releases heat, the water in the adsorption and desorption bed 9 is absorbed to regenerate the metal salt water complex, so that the temperature of the circuit board 4 and the battery assembly of the scooter is controlled.

As shown in fig. 4, the end of the heat conduction column 7 is vertically fixed with a heat conduction plate 11, and the heat conduction plate 11 is pressed against the top surface of the adsorption/desorption bed 9. The heat conduction column 7 is preferably made of heat conduction glue, the heat conduction plate 11 is preferably made of aluminum metal, and the heat conduction plate is light in weight and good in heat conduction effect. The heat conduction columns 7 transfer the heat on the battery substrate 3 and the circuit board 4 to the heat conduction plate 11, and further transfer the heat into the energy storage core 10 through the heat conduction plate 11.

Wherein, the inner wall of the heat dissipation base 8 is provided with a clamping groove corresponding to the heat conducting plate 11, and the heat conducting plate 11 is limited on the adsorption and desorption bed 9 through the clamping groove so as to keep the pressure of the heat conducting plate 11 on the adsorption and desorption bed 9. The adsorption and desorption bed 9 and the energy storage core 10 are in a block shape which is laid down, the contact area between the flaky heat conducting plate 11 and the adsorption and desorption bed 9 is large, and the heat conducting effect can be enhanced.

The center axis of the battery substrate 3 is provided with a supporting plate 12, a supporting seat 13 is arranged in a shell 14 corresponding to the supporting plate 12 along the center axis, the supporting plate 12 is fixedly connected to the supporting seat 13 to support the battery substrate 3, a space is reserved between the battery substrate 3 and the inner wall of the shell 14, and the heat dissipation structure is arranged in the space. In addition, the stay plate 12 supports the battery substrate 3 to ensure stable installation of the battery substrate 3 within the case 14.
