Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a structure for defrosting a car door and a car. Background Technology

[0002] Automotive weatherstripping is a crucial functional component of vehicles, primarily used for dustproofing, sound insulation, waterproofing, and heat insulation. Traditional weatherstripping often uses EPDM rubber or synthetic rubber materials. While these materials offer weather resistance, their operating temperature range is generally limited to -40℃ to 90℃. Their performance limitations become increasingly apparent in extreme environments such as low temperatures and high humidity. Weatherstripping at car windows and doors is prone to icing in cold climates, leading to problems such as difficulty in opening doors and reduced sealing.

[0003] With the continuous advancement of automotive technology and the increasing demands for comfort from users, heated weatherstripping is gradually becoming an emerging technology. This innovative technology aims to solve the problem of traditional weatherstripping easily freezing and icing in cold weather, while simultaneously improving in-vehicle comfort and safety.

[0004] Existing heated sealing strips mainly employ embedded heating wires or heating elements, which suffer from uneven heating and poor durability. Furthermore, the heating wires need to be interconnected, resulting in a complex structure. Temperature control of the heating wires or heating elements is also a critical limitation. To prevent overheating or underheating, a temperature control module is required, and a temperature measuring device also needs to be installed on the sealing strip. This leads to a complex product structure, excessive space occupation, high cost, and significantly reduced practicality. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0021] like Figure 1 and Figure 5 As shown, the first heating sealing strip 1 is disposed on the upper section of the B-pillar of the vehicle. The second heating sealing strip 2 is disposed on the lower section of the B-pillar of the vehicle. Both the first heating sealing strip 1 and the second heating sealing strip 2 are provided with strip-shaped conductive rubber 4. The first heating sealing strip 1 and the second heating sealing strip 2 are adapted to be energized when the front door of the vehicle is frozen, so that the temperature of the first heating sealing strip 1 and the second heating sealing strip 2 increases to melt the ice at the front door.

Figure 6The "-" in the diagram indicates that the other copper wire 5 is connected to the negative terminal of the power supply. The insulating rubber 6 wraps around the conductive rubber 4. A switch can be installed between the copper wire 5 and the power supply, which is suitable for activating and deactivating the heating of the heating seal strip. When the two copper wires 5 are energized, a current is generated in the conductive rubber 4 between them, thereby generating heat and achieving a heating effect. The conductive rubber 4 heats up evenly, thus melting the ice and removing it, solving the problem of difficulty in opening the front and rear doors in extremely cold conditions. The heat is evenly distributed through the conductive rubber 4, effectively preventing localized overheating.

[0024] Specifically, the conductive filler in the conductive rubber 4 is graphene. The proportion of graphene in the conductive rubber 4 ranges from 1% to 3%.

[0029] Specifically, such as Figure 3 As shown, the second heated sealing strip 2 is located between the front door sheet metal 9 and the rear door sheet metal 10.
