Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle door handles, in particular to a graphene-heated new energy vehicle door handle. Background Art

[0002] In today's global automotive market, new energy vehicles are rising at an astonishing rate and gradually becoming the mainstream choice. New energy vehicles generally refer to vehicles that are powered by unconventional automotive energy such as electricity and hydrogen. Compared with traditional fuel vehicles, new energy vehicles have demonstrated many significant advantages, which are not only reflected in environmental performance and energy efficiency, but also in driving experience and cost-effectiveness.

[0003] At present, new energy vehicles mainly use hidden door handles to reduce air turbulence and resistance, improve the aerodynamic characteristics of the vehicle, thereby reducing the drag coefficient and increasing the cruising range. However, in low temperature environments, hidden door handles are easily frozen, resulting in an inability to open normally. The safety of the hidden door handles can be enhanced by heating the door handles, but the existing heating method cannot evenly cover the door handles, which is prone to uneven heating and reduces practicality.

[0004] Therefore, a new type of graphene-heated new energy vehicle door handle is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a graphene-heated new energy vehicle door handle to solve the problem that the heating method proposed in the above background technology cannot evenly cover the door handle, easily resulting in uneven heating effect and reduced practicality.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a graphene-heated new energy vehicle door handle, comprising a door handle upper cover and a door handle bottom cover, wherein the door handle bottom cover is connected to the door handle upper cover to form a door handle cavity, and a graphene heating component is disposed in the door handle cavity;

[0007] The graphene heating component includes a base film, a graphene heating layer, and a silver wire. The graphene heating layer is composed of several groups of graphene carbon strips. The graphene carbon strips are arc-shaped, and the resistance value of each group of graphene carbon strips is equal. The silver wire and the graphene carbon strips are printed on the base film. There are two silver wires, which are respectively arranged at the two ends of the graphene carbon strips and overlap with the graphene carbon strips. The several groups of graphene carbon strips and the silver wires form a parallel circuit.

[0008] Preferably, the base film extends from one end to the other end, and its width gradually narrows, and the curvature of the arc of the graphene carbon strip close to the narrow end of the base film increases.

[0009] Preferably, the graphene heating component is connected to the door handle cover through a double-sided adhesive layer.

[0010] Preferably, an outer membrane is fixedly connected to the surface of the door handle bottom cover.

[0011] Preferably, the silver wire is fixedly connected to a terminal, and the terminal is connected to a wiring harness.

[0012] Preferably, the center of the rear end of the door handle bottom cover is recessed inward and has an inner groove, positioning blocks are symmetrically fixedly connected on both sides of the inner groove of the door handle bottom cover, and a reinforcing inner layer is fitted on the inner wall of the inner groove of the door handle bottom cover.

[0013] Preferably, the rear end of the reinforced inner layer is fixedly connected to the internal anti-slip layer, and a circle of mounting grooves is provided on the surface of the positioning block. The rear ends of the reinforced inner layer and the internal anti-slip layer are sleeved on the outside of the positioning block and inserted and fixed in the mounting grooves.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the graphene-heated new energy vehicle door handle not only realizes uniform heating function and strong fixing function, but also realizes anti-slip protection function;

[0015] By providing a graphene heating layer, silver wires, graphene carbon strips, a bottom film, and a door handle cavity, an independent placement space, the door handle cavity, is formed between the door handle cover and the door handle bottom cover. The graphene heating layer is located in the door handle cavity, and two silver wires are installed at both ends of the graphene carbon strips. The silver wires' inherent electrical and thermal conductivity enhances the heating effect on the surface of the door handle cover and the door handle bottom cover. At the same time, multiple groups of graphene carbon strips are sequentially fixed to the surface of the graphene heating layer, and each group of graphene carbon strips has the same resistance value, ensuring that the door handle cover and the door handle bottom cover are heated evenly. By adding a bottom film, which narrows as the curvature of the graphene carbon strips changes, the graphene heating layer is effectively fixed in the door handle cavity, effectively preventing the graphene heating layer from shifting during use, which reduces the heating effect. The graphene heating layer has the beneficial effects of high heating efficiency and low energy consumption.

[0016] By providing terminals, wiring harnesses and double-sided adhesive layers, the terminals and wiring harnesses cooperate with each other to connect the wires, ensure the overall heating effect of the door handle, enhance the stability of the contact interface of the graphene heating layer, generate heat when current passes through the graphene, ensure the stable heating of the door handle cover and the door handle bottom cover, and enhance the stability of the internal structure itself through the double-sided adhesive layer, ensure the firmness between the door handle cover and the door handle bottom cover, and avoid falling off at the connection between the two.

[0017] By providing a positioning block, an installation groove, an internal anti-slip layer and a reinforced inner layer, both sides of the internal anti-slip layer and the reinforced inner layer are sleeved on the outside of the corresponding positioning block, and are fixed in the installation groove by means of plug-in connection, ensuring that the internal anti-slip layer and the reinforced inner layer are fitted to the inner groove surface of the door handle bottom cover, thereby enhancing the anti-slip property of the inner groove surface of the door handle bottom cover during use, and enhancing the strength to avoid breakage of the protective material.

[0028] Specifically, if Figure 1 and Figure 2 As shown, when in use, an independent placement space door handle cavity 6 is formed between the door handle upper cover 1 and the door handle bottom cover 3, the graphene heating layer 9 is located in the door handle cavity 6, and two silver wires 8 are installed at both ends of the graphene carbon strip 10. The electrical conductivity and thermal conductivity of the silver wire 8 are used to enhance the heating effect on the surface of the door handle upper cover 1 and the door handle bottom cover 3.

[0029] The graphene heating component is connected to the door handle upper cover 1 through a double-sided adhesive layer 7; the surface of the door handle bottom cover 3 is fixedly connected with an outer film 15.

[0030] Specifically, if Figure 1 and Figure 3 As shown, when in use, the terminal 12 and the wiring harness 11 cooperate with each other to connect the wires, ensure the overall heating effect of the door handle, enhance the stability of the contact interface of the graphene heating layer 9, generate heat when the current passes through the graphene, ensure the heating stability of the door handle upper cover 1 and the door handle bottom cover 3, and enhance the stability of the internal structure itself through the double-sided adhesive layer 7.
