[0002] With the increasing popularity of electric two-wheelers, battery charging efficiency has become a concern. In low temperatures, low battery charging efficiency reduces battery capacity and weakens battery performance, affecting the range of electric two-wheelers and causing inconvenience to people's travel. Therefore, improvements are needed. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies where low temperatures negatively impact battery performance by providing a novel heating structure for a battery seat.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0005] A seat bucket battery heating structure includes a controller module, a frame, a seat bucket, and a battery assembly. The battery assembly is fixed inside the seat bucket. The structure also includes a ventilation duct assembly and a hot air assembly. The seat bucket is fixed to the frame. The frame has a head tube, which is hollow. The hot air assembly has a hot air space. The ventilation duct assembly connects the inside of the head tube, the hot air space, and the inside space of the seat bucket. There is a gap between the battery assembly and the inner wall of the seat bucket. The controller module is electrically connected to both the battery assembly and the hot air assembly.

[0006] At low temperatures, battery charging efficiency is low, battery capacity decreases, and weakened battery performance affects the range of electric two-wheelers, causing inconvenience for travelers. The heating element and ventilation duct assembly work together to transfer hot air into the seat compartment to heat the battery pack, preventing the battery pack from reducing capacity due to low temperatures and impacting travel. The frame has a hollow head tube, into which the ventilation duct assembly is inserted. The gaps in the frame itself act as a filter, reducing the amount of debris entering the heating space.

[0007] Preferably, in the above-described seat bucket battery heating structure, the hot air assembly includes an air guide pipe, an exhaust pipe, a heater, and a fan. The ventilation pipe assembly includes an air inlet pipe and an air outlet pipe. The front end of the air inlet pipe is connected to the head tube, the rear end of the air inlet pipe is connected to the front end of the air guide pipe, the rear end of the air guide pipe is connected to the front end of the exhaust pipe, the rear end of the exhaust pipe is connected to the front end of the air outlet pipe, and the rear end of the air outlet pipe is connected to the internal space of the seat bucket. The spaces inside the air guide pipe and the exhaust pipe together form the hot air space. The heater and the fan are fixed within the hot air space, and the controller module is electrically connected to the heater and the fan, respectively.

[0008] The air inlet duct connects the head tube to the air guide duct, and the air outlet duct connects the exhaust duct to the seat. The space inside the air guide duct and the exhaust duct together forms the hot air space. The relatively enclosed space makes it easier for the heater to accumulate heat in the heating space. The hot air assembly includes a heater and a fan. The controller module is electrically connected to the heater and the fan respectively. When the seat needs to be cooled, the fan can be controlled to operate independently.

[0009] Preferably, in the above-described battery heating structure for a seat bucket, the fan is fixed to the air guide pipe, the heater is fixed inside the exhaust pipe, and the hot air assembly further includes an extension pipe, wherein the air guide pipe and the exhaust pipe are connected by the extension pipe.

[0014] The combination of the duct flange and the extension tube step can provide a certain degree of sealing, and at the same time make the connection between the duct and the extension tube more stable.

[0015] Preferably, in the above-described battery heating structure for a seat bucket, the extended tube is provided with an extended tube flange, and the exhaust tube is provided with an exhaust tube step, wherein the extended tube flange cooperates with the exhaust tube step.

[0016] The extension pipe flange, when combined with the exhaust pipe step, can provide a certain degree of sealing and also make the connection between the exhaust pipe fitting and the extension pipe fitting more stable.

[0017] Preferably, in the above-described battery heating structure for a seat bucket, the air guide pipe is provided with a first fixing block, the extended pipe is provided with a second fixing block, and the exhaust pipe is provided with a third fixing block. The first fixing block, the second fixing block, and the third fixing block are in corresponding positions, equal in number, and at least one in number. The first fixing block, the second fixing block, and the third fixing block are fastened together by screws or pins.

[0018] The first fixing block, the second fixing block, and the third fixing block are fastened together with screws or pins, making the connection between the extended pipe fitting and the exhaust pipe fitting tighter.

[0019] Preferably, the aforementioned seat bucket battery heating structure further includes a bottom air guide plate. The bottom of the seat bucket is provided with a seat bucket air inlet.

The seat bucket air inlet, the bottom air guide port, and the bottom air guide groove are connected.

[0020] The bottom air guide plate creates a gap between the battery assembly and the bottom of the seat, which facilitates the flow of hot air and makes heating more even.

[0021] Preferably, in the above-described battery heating structure for a seat bucket, the bottom air guide plate is further provided with a bottom air duct baffle, which is disposed above the bottom air guide port.

[0022] The bottom air duct baffle can prevent hot air from directly hitting the battery pack and causing localized overheating of the battery pack.

[0031] Preferably, in the above-described battery heating structure for a seat bucket, the seat bucket is provided with a seat bucket mesh at the seat bucket air inlet.

[0032] The mesh design of the seat bucket prevents debris from the heating and ventilation components from entering the seat bucket, thus protecting the battery components while also ensuring breathability.

[0033] Preferably, in the above-described battery heating structure for a seat, a flexible sealing plug is provided on the seat, and a wire outlet hole is provided on the flexible sealing plug.

[0034] The flexible sealing plug creates a relatively sealed space inside the tub, resulting in better heat preservation.

[0036] The inner convex part can restrict the horizontal movement of the battery pack, so that the battery pack will not be damaged by bumps during the operation of the electric vehicle. The longitudinal air guide channel facilitates the airflow inside the seat bucket, making the airflow inside the seat bucket faster, thereby ensuring more uniform heating of the battery pack.

[0037] Preferably, in the above-described battery heating structure for a seat bucket, the number of the inner protrusions is at least three.

[0038] The number of internal protrusions should be at least three to better ensure the efficiency of gas flow inside the seat.

[0039] Preferably, in the above-described battery heating structure for a seat bucket, the tops of each of the longitudinal air guide slots are connected.

[0040] The top of the longitudinal air guide duct is connected, which helps to integrate the airflow and improve the gas flow efficiency.
