Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicles, in particular to a split battery heating bracket structure. Background Art

[0002] As electric two-wheelers become more and more popular, the vehicle's endurance has become an important criterion for consumers to consider. The activity of lead-acid batteries is seriously affected by temperature. In winter, when the temperature is low, the battery capacity is greatly reduced, resulting in a decrease in mileage and affecting the user experience. One solution is to increase the charging power in winter to charge the battery more, but this can easily shorten the battery life. Therefore, improvements need to be made to the above problems. Summary of the invention

[0003] The utility model aims at the defects of the prior art such as reduced driving range in winter, and provides a new split battery heating bracket structure.

[0004] In order to solve the above technical problems, the utility model is implemented through the following technical solutions:

[0005] A split battery heating bracket structure includes a battery part, a battery pack is arranged on the outside of the battery part, and also includes a heating plate, a reflective film, and a heating bracket. A battery box is arranged at the bottom of the battery part. The heating plate and the reflective film are fixed in the heating bracket, and the heating bracket is located between the battery part and the battery box.

[0006] The battery pack is used to keep the battery warm and protect it. The heating plate is used to heat the battery, increase the battery temperature, and ensure the range in winter. After the temperature is increased, the charging effect can be improved to ensure the battery life. The reflective film is used to reflect heat and enhance the thermal insulation performance of the battery. The heating bracket is used to install the heating plate, reflective film, and support the battery. The battery box is used to place the battery pack formed by the battery and the heating bracket, and also plays a role in heat preservation and protection.

[0007] The utility model realizes heating and heat preservation of the battery part through the above design, ensuring the winter driving range and battery life. The split heating bracket integrated with the heating plate and the reflective film can be adapted to the battery installation, which improves the applicability of the utility model.

[0008] Preferably, in the above-mentioned split battery heating bracket structure, the heating bracket is provided with supporting steps, and the supporting steps are enclosed to form a mounting groove.

[0009] The installation groove is used to install the heating plate and reflective film. The support step is used to support the battery part, raise the battery part, make the installation groove have a certain depth, prevent the battery part from direct contact, thereby avoiding the heating plate from being damaged by pressure, and also avoiding the safety problem of uneven heating caused by direct contact with the heating battery part. The heating plate first heats the bottom air and then conducts it to the battery part, so that the battery part is heated more evenly, and there will be no local or single-cell overtemperature, which prevents the battery from burning out.

[0010] Preferably, in the above-mentioned split battery heating bracket structure, a splicing buckle structure is arranged around the heating bracket.

[0011] Through the splicing snap-on structure, multiple heating brackets can be spliced ​​and used, further realizing the split design. They can also be combined into different shapes to match more battery layouts, further improving versatility.

[0012] Preferably, the above-mentioned split battery heating bracket structure further includes a temperature probe, the support step is provided with a probe slot, and the temperature probe is fixed in the probe slot.

[0013] The temperature probe is used to collect the temperature at the bottom of the battery. When the temperature is too low, the heating plate starts to heat. When the temperature is too high, the heating stops to protect the battery, so that the battery is always in the optimal operating temperature range. The probe slot is used to install the temperature probe, which improves the structural stability.

[0014] Preferably, in the above-mentioned split battery heating bracket structure, the mounting groove is provided with an avoidance groove, the heating plate is provided with a wiring terminal, and the avoidance groove cooperates with the wiring terminal.

[0015] The avoidance groove is used to leave space for the terminal to avoid damage to the terminal. The terminal of the heating plate is thick and easy to contact with the battery. Once the rubber coating is worn due to long-term friction, there will be a risk of short circuit. The avoidance groove can allow a certain space at the bottom of the terminal to reduce the impact caused by friction.

[0016] Preferably, in the above-described split battery heating bracket structure, a receiving space is provided on the back of the supporting step, and a wiring harness port is provided in the receiving space, the wiring harness port is connected to the avoidance groove, and the wiring harness port cooperates with the wiring terminal.

[0017] The accommodation space is mainly used to accommodate the wiring harness. The wiring harness port is connected to the avoidance groove, so that the wiring harness connected to the terminal can enter the accommodation space from the wiring harness port. The accommodation space can protect the wiring harness from being squeezed by the battery part, prevent the risk of short circuit caused by damage to the wiring harness insulation rubber, and also improve the front appearance.

[0018] Preferably, in the above-mentioned split battery heating bracket structure, the accommodating space is provided with a wiring harness buckle.

[0019] The wiring harness clips are used to fix the wiring harness to prevent it from shaking and falling out of the accommodation space and getting damaged, thus ensuring structural stability.

[0020] Preferably, in the above-mentioned split battery heating bracket structure, the reflective film is provided with an aluminum foil reflective layer.

[0021] The heating plate generates heat on both sides, and the aluminum foil reflective layer can reflect the heat conducted downward by the heating plate and conduct it upward to the battery part, thereby increasing the heat utilization rate and improving the thermal insulation performance of the battery part.

[0022] Preferably, in the above-mentioned split battery heating bracket structure, the battery pack has a double-layer structure with inner insulation and outer reflection.

[0023] The double-layer structure of inner insulation and outer reflection, the inner layer is the insulation layer and the outer layer is the reflection layer, which can minimize the heat loss of the battery part and improve the thermal insulation performance.

[0024] Preferably, in the above-described split battery heating bracket structure, the heating bracket is arranged front to back, left to right, or in a T-shaped arrangement by splicing a snap-fit ​​structure.

[0025] The heating bracket can form a variety of arrangements by splicing the snap-on structure, which improves versatility and adapts to more battery installation methods. BRIEF DESCRIPTION OF THE DRAWINGS
