Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile accessories, in particular to a small door for a vehicle and a vehicle. Background Art
[0002] As important components of modern cars, the fuel tank cap and the charging protection cap each carry a protection and safety mission: the fuel tank cap ensures the sealing and anti-theft security of fuel storage, while the charging protection cap maintains the cleanliness and safe accessibility of the electric vehicle charging port.
[0003] In the cold winter, these small doors for cars, especially the fuel tank caps and charging protective caps of electric vehicles, are often difficult to open due to snow accumulation, ice or mechanical parts shrinkage caused by low temperatures, affecting the user experience and the convenience of vehicle maintenance. Modern car designs have considered adding heating devices to the fuel tank caps or charging protective caps to prevent mechanical contraction caused by ice and snow accumulation and low temperatures, and ensure that these small doors can still operate freely in low temperature environments. However, in actual applications, it is found that a common challenge of existing heating design solutions is that the heating distribution is not uniform, resulting in a slow thawing process of the fuel tank caps and charging protective caps, which in turn increases the waiting time for users. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a small door for a vehicle and a vehicle in view of the current status of the prior art.
[0005] The technical solution adopted by the utility model to solve the above technical problems is: to propose a small door for a vehicle, comprising:
[0006] A fixing seat, which is installed on the vehicle body;
[0007] A cover plate hinged on the fixing seat;
[0008] A heating unit is arranged on a side of the cover plate close to the fixing seat, and the heating unit has a heating element and a fan. The heating element is arranged in the cover plate and is used to heat the cover plate. The fan is arranged in the cover plate and is located in the center of the cover plate. The fan is linked with the heating element to evenly distribute heat in the cover plate.
[0009] In the above-mentioned small door for a vehicle, a base plate is further connected to the cover plate, and the heating unit is located between the cover plate and the base plate.
[0010] In the above-mentioned small door for a vehicle, a cavity is formed between the cover plate and the base plate, and the heating unit is located in the cavity.
[0011] In the above-mentioned small door for a vehicle, the heating element is an annular structure and is closely attached to the inner wall of the cavity.
[0012] In the above-mentioned small door for a vehicle, a groove is provided on the base plate, and the fan is connected in the groove.
[0013] A car comprises any one of the above-mentioned small doors.
[0014] Compared with the prior art, the advantage of the present invention is that a heating unit is arranged on the cover plate, and the heating unit has a heating element and a fan. Once the cover plate is difficult to open due to snow, ice or low temperature, the system activates the heating unit, and the heating element immediately applies heat to the cover plate. At this time, the fan starts synchronously to enhance the air circulation around the cover plate, promote the even distribution of heat on the surface of the cover plate, accelerate the thawing process, and significantly shorten the user's waiting time.

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0021] like Figures 1 to 4 As shown, a small door for a vehicle of the utility model comprises:
[0022] A fixing seat 1, which is installed on the vehicle body;
[0023] A cover plate 2, which is hinged on the fixing base 1;
[0024] The heating unit 3 is arranged on one side of the cover plate 2 close to the fixed seat 1. The heating unit 3 has a heating element 4 and a fan 5. The heating element 4 is arranged in the cover plate 2 and is used to heat the cover plate 2. The fan 5 is arranged in the cover plate 2 and is located in the center of the cover plate. The fan 5 is linked with the heating element 4 to evenly distribute the heat in the cover plate 2.
[0025] The fixing base 1 can be firmly connected to the car body by threaded connection or clip connection. The hinged cover 2 thereon effectively seals the fuel filler port or charging port to ensure its sealing. The on-board power supply continuously supplies power to the heating unit 3, and the switching state of the heating unit 3 can be conveniently controlled through the car center console. Once the cover 2 is difficult to open due to snow, ice or low temperature, the system activates the heating unit 3, and the heating element 4 immediately applies heat to the cover 2. At this time, the fan 5 starts synchronously to enhance the airflow circulation around the cover 2, promote the even distribution of heat on the surface of the cover 2, accelerate the thawing process, and significantly shorten the user's waiting time.
[0026] Furthermore, a substrate 6 is connected to the cover plate 2, and the heating unit 3 is located between the cover plate 2 and the substrate 6. The substrate 6 can be fixed to the cover plate 2 by means of screws, welding, or snaps, and a multi-layer structure is formed between the two. The provision of the substrate 6 not only enhances the structural strength of the cover plate 2, but also provides a stable installation platform for the heating unit 3.
[0027] Specifically, a cavity 7 is formed between the cover plate 2 and the substrate 6, and the heating unit 3 is located in the cavity 7. The setting of the cavity 7 helps to gather and guide the heat generated by the heating unit 3, and through heat conduction or convection, the heat is more effectively transferred to the cover plate 2 that needs to be heated, thereby accelerating the thawing process or maintaining a suitable temperature in a low temperature environment. By constructing the cavity 7 between the cover plate 2 and the substrate 6 and building in the heating unit 3, not only the efficient heating performance is ensured, but also the stability and long-term durability of the heating unit 3 are improved, while taking into account the beautiful appearance of the vehicle and the convenience of practical application.
[0028] Furthermore, the heating element 4 is an annular structure, which is in close contact with the inner wall of the cavity 7. The advantage of this shape is that it can evenly surround the target area and ensure that heat is transferred to every part of the cover plate 2, especially the edges, which is crucial for accelerating thawing and maintaining temperature uniformity.
[0029] As an embodiment of the present solution, the heating element 4 can be a heating plate, which is a common heating element that generates heat by passing an electric current through a resistive material. They are thin and flexible, suitable for fitting complex curved surfaces, can respond quickly, and provide a uniform thermal field.
[0030] As another embodiment of the present solution, the heating element 4 can also be a resistance wire type, which is usually composed of a metal wire with high resistivity such as nickel-chromium alloy. The resistance wire is known for its significant cost-effectiveness, excellent plasticity (easy to shape to adapt to a wide range of structural designs) and rapid heating response. It is particularly suitable for use in application scenarios where space is compact or local centralized heating is required, because it can efficiently convert electrical energy into thermal energy and generate a thermal effect when current passes through.
[0031] Furthermore, a groove 8 is provided on the base plate 6, and the fan 5 is connected in the groove 8. This ingenious design not only ensures the stable positioning of the fan 5, but also promotes the uniform dispersion of the heat flow generated by the heating element 4 through the effective guidance of the fan 5, thereby improving the convenience and reliability of the entire vehicle door in low temperature environments.
[0032] The present solution also proposes a car, comprising any one of the above-mentioned small vehicle doors, wherein the above-mentioned small vehicle door is arranged on the car body.
