Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a battery structure with a heat-insulating battery box. Background Art

[0002] As a convenient and environmentally friendly means of transportation, electric two-wheelers have played an increasingly important role in urban travel in recent years. With the rapid development of the electric two-wheeler market, the stability and safety of its battery performance have gradually become prominent. In particular, under different environmental conditions, the temperature change of the battery has a significant impact on the performance and service life of the electric two-wheeler.

[0003] At present, the main battery type used in electric two-wheeled vehicles is lead-acid batteries, which have advantages such as high energy density, long cycle life and low self-discharge rate, but also have disadvantages that they are significantly affected by temperature. In low temperature environments, the chemical reaction inside the lead-acid battery slows down, the battery performance decreases, and it cannot provide sufficient power. Therefore, it is necessary to improve the above problems. Summary of the invention

[0004] The utility model aims at the defects of the prior art such as the degradation of battery performance in a low temperature environment, and provides a new battery structure with a heat-insulating battery box.

[0005] In order to solve the above technical problems, the utility model is implemented through the following technical solutions:

[0006] A battery structure with a heat-insulating battery box includes a battery part, a supporting and lifting base, a heat-insulating box, and a heating plate. The heating plate is fixed to the bottom of the supporting and lifting base, the battery part is fixed in the supporting and lifting base, and the heat-insulating box is sleeved on the battery part.

[0007] The supporting and lifting base is used to fix the battery part, and is also used to cooperate with the external frame to support and fix it. It is also used to raise the battery part to prevent the battery part from directly contacting the heating plate. If the battery part directly contacts the heating plate, the battery part is likely to crush the heating plate; if the heating plate directly contacts and heats the battery part, it is easy to cause local overheating of the battery part, which is very dangerous. The insulation box has a heat preservation function to reduce the heat loss of the battery part. The heating plate has a heating function to prevent the battery part from being too low.

[0008] The utility model realizes the heat preservation function of the battery box through the design, has a stable structure, is detachable and optional, and has strong versatility.

[0009] Preferably, in the above-mentioned battery structure with a heat-insulating battery box, both sides of the supporting elevated base are provided with elevated steps, and the elevated steps cooperate with the battery part.

[0010] The raised step serves as a step, and the battery part is fixed on the raised step, thereby raising the battery part and preventing the battery part from directly contacting the heating sheet.

[0011] Preferably, in the battery structure with a heat-insulated battery box described above, the raised step is an inwardly concave L-shaped structure.

[0012] The inwardly concave design improves the space utilization rate, and the L-shaped structure design improves the structural strength.

[0013] Preferably, in the battery structure with a heat-insulated battery box described above, the bottom of the supporting and raising base is provided with a long supporting part and a short supporting part.

[0014] The long supporting part and the short supporting part are used to cooperate with the main supporting bar and the auxiliary supporting bar of the external vehicle frame for supporting and fixing.

[0015] Preferably, in the battery structure with a heat-insulated battery box described above, the long supporting part and the short supporting part are distributed in a "艹" shape.

[0016] The "艹" shape distribution design makes the supporting force more uniform, improving the structural stability and service life.

[0017] Preferably, in the battery structure with a heat-insulated battery box described above, it further includes a side raising block, and the side raising block cooperates with the battery part.

[0018] The side raising block is used to cooperate with the raising and fixing of the battery part, so as to adapt to the fixing of more types of battery parts.

[0019] Preferably, in the battery structure with a heat-insulated battery box described above, it further includes a filling box, and the filling box cooperates with the battery part.

[0020] The filling box is used to cooperate with the fixing of the battery part, playing a role in filling the space and assisting in fixing, so as to adapt to the fixing of more types of battery parts. BRIEF DESCRIPTION OF THE DRAWINGS
