Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a lead-acid battery heating bracket structure. Background Art

[0002] As electric two-wheelers become more and more popular, vehicle endurance has become an important criterion for consumers. 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, which causes trouble for users. In addition, in order to charge the battery more in winter, charging power is often increased, which can easily shorten the battery life, so improvements are needed. Summary of the invention

[0003] The utility model aims at the defect in the prior art that the activity of lead-acid batteries is seriously affected by temperature, and provides a new lead-acid 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 lead-acid battery heating support structure comprises a battery pressure strip, a battery insulation bag, a battery assembly, a heating plate, a temperature probe, a protective support and a battery box, wherein the protective support is placed in the battery box, the battery insulation bag is sleeved on the battery assembly, the protective support is provided with a placement groove, and support steps are provided around the placement groove, the heating plate is placed in the placement groove, the battery assembly is placed on the support step, there is a gap between the heating plate and the bottom of the battery assembly, the temperature probe is electrically connected to the heating plate, and the battery pressure strip cooperates with the battery box to press the battery insulation bag, the battery assembly and the protective support.

[0006] This structural design allows the battery assembly to be heated in a controlled environment while maintaining an appropriate gap with the heating plate. The gap can prevent overheating of the battery and allow the battery assembly to be heated more evenly, ensuring the performance and life of the battery assembly. It can also prevent the battery assembly from squeezing the heating plate too hard and causing damage to the heating plate.

[0007] The temperature probe is used to control the heating plate. When the temperature is lower than the optimal operating temperature range of the battery assembly, the heating plate is controlled to heat. When the temperature is close to or higher than the optimal operating temperature range, the heating plate is controlled to stop heating.

[0008] Battery insulation packs are used to keep battery components warm and reduce heat loss.

[0009] The battery pressure strip cooperates with the battery box to press the battery assembly tightly through screws to prevent the battery assembly from bumping and jumping during riding, damaging the heating plate, and even affecting riding safety.

[0010] Preferably, the lead-acid battery heating bracket structure described above further includes a reflective film, and the reflective film is placed under the heating plate.

[0011] The heating plate generates heat on both sides, and the reflective film can reflect the heat conducted to the bottom and conduct it upwards, maximizing the use of heat.

[0012] Preferably, in the lead-acid battery heating bracket structure described above, the protection bracket is provided with an avoidance groove connected to the placement groove, and the connection terminal of the heating plate is placed in the avoidance groove.

[0013] The thickness of the heating plate terminal is relatively thick, and the terminal is easy to contact with the battery. Long-term friction causes the rubber coating to wear and there is a risk of short circuit. Adding avoidance grooves can allow a certain space between the terminal and the bottom of the battery assembly to reduce the impact caused by friction.

[0014] Preferably, in the above-mentioned lead-acid battery heating bracket structure, the protection bracket is provided with a probe slot, and the temperature probe is placed in the probe slot.

[0015] The probe slot is used to install the temperature probe. The temperature probe and wiring harness are fixed in the slot to prevent the temperature probe from moving while the vehicle is riding, which would cause inaccurate temperature measurement.

[0016] Preferably, in the above-mentioned lead-acid battery heating bracket structure, the probe slot is arranged on the supporting step.

[0017] The probe card slot is placed on the supporting step, so that the probe can be closer to the battery assembly for temperature measurement and avoid being affected by the heating plate in the slot.

[0018] Preferably, in the lead-acid battery heating bracket structure described above, battery baffles are provided on both sides of the protective bracket, and the battery baffles are abutted against both sides of the battery insulation package.

[0019] The battery assembly is installed on the battery guard bars on both sides and in the middle to prevent the battery assembly from moving left and right during riding, crushing the heating plate and even affecting safe riding.

[0020] Preferably, in the above-mentioned lead-acid battery heating bracket structure, the top layer of the reflective film is aluminum foil.

[0021] As the top layer of the reflective film, aluminum foil can reflect heat more effectively and improve heating efficiency due to its good heat reflective properties. At the same time, the corrosion resistance of aluminum foil also helps to improve the durability of the reflective film.

[0022] Preferably, in the lead-acid battery heating bracket structure described above, a limiting block is provided on the bottom surface of the protective bracket, and a limiting hole is provided on the battery box, and the limiting block cooperates with the limiting hole.

[0023] The coordinated use of the limit block and the limit hole can ensure the accurate position of the protective bracket in the battery box, prevent displacement during transportation or use, and thus ensure the stability of the entire heating bracket structure.

[0024] Preferably, in the lead-acid battery heating bracket structure described above, the battery insulation package is a double-layer structure, the outer layer is a reflective layer, and the inner layer is a thermal insulation layer.

[0025] The design of the double-layer insulation bag has an outer reflective layer that can reflect part of the heat and reduce heat loss to the outside, while the inner insulation layer can maintain the temperature of the battery components, improve the insulation effect, and ensure that the battery works at an appropriate temperature.
