Description

Vehicle lampshade with heating module

The present invention relates to a vehicle lampshade, and more particularly to a vehicle lampshade having a heating module.

For cars or related vehicles, if the headlights are covered by snow or freezing rain, they will not be able to illuminate the road ahead, which is not conducive to driving safety. In the same way, if the taillights are covered by snow or freezing rain, the vehicles in the rear will not be able to notice the vehicles in front, which is not conducive to driving safety. In addition, as LEDs are gradually applied to automotive transportation lighting tools, although LED lamps can generate heat, it is still difficult to achieve snow melting effect. Because the heat generated by LED lamps is still lower than that of halogen lamps, HIDs, etc., it is impossible to melt the snow, freezing rain or hail accumulated above the lamp housing. Based on this, how to effectively solve the above problems is actually a problem that relevant industry players must think about and solve.

One of the purposes of this creation is to provide a vehicle lampshade with a heating module that quickly melts snow.

To achieve the above objective, the present invention provides a vehicle lampshade having a heat generating module, comprising a light transmissive cover and a heat generating module. The light transmissive cover has a corresponding inner surface and an outer surface. The heating module comprises at least one heating wire, a non-conductor film on which the heating wire is disposed, a flexible circuit board electrically connected to one end of the heating wire, and at least one power conductor electrically connected to the flexible circuit board. The heat-generating wire clip is placed between the non-conductor film and the inner surface of the light-transmitting cover body to transfer heat to the outer surface of the light-transmitting cover body.

Preferably, the number of the heat generating wires, the flexible circuit board and the power conductor are respectively two.

Preferably, the non-conductor film further has a protrusion corresponding to the flexible circuit board.

Preferably, the shape of the heat-generating wire, the shape of the non-conductor film, and the shape of the light-transmitting cover correspond to each other.

Preferably, the shape of the heat-generating wire, the shape of the non-conductor film and the light-transmitting cover are respectively a circle, a rectangle or an ellipse.

Preferably, the heat generating wire has a wire diameter of less than 100 micrometers (μm).

The creation also has the following effects. The heat generating module of the present invention has a compact structure, is fast, easy to manufacture, and low in cost.

The detailed description and technical content of the present invention are described below with reference to the drawings, but the drawings are only for reference and explanation, and are not intended to limit the creation.

As shown in FIG. 1 to FIG. 3 , the present invention provides a vehicle lampshade 10 having a heat generating module, comprising a transparent cover 1 and a heat generating module 2 . The vehicle shade 10 described herein includes, but is not limited to, a light cover 10 on an automobile, a motor vehicle, a vehicle, a flight vehicle, or a space rocket.

The transparent cover 1 has a corresponding inner surface 11 and an outer surface 12. The heating module 2 includes at least one heating wire 21, a non-conductor film 22 on which the heating wire 21 is disposed, a flexible circuit board 23 electrically connected to one end of the heating wire 21, and at least one power conductor 24 electrically connected to the flexible circuit board 23. . The power supply conductor 24 is connected to, for example, a connector (not shown) to be coupled to, for example, a generator (not shown) to provide heat to the heat generating wire 21 to generate heat.

The heat-generating wire 21 shown in FIG. 3 is interposed between the non-conductor film 22 and the inner surface 11 of the light-transmitting cover 1, and when energized, the heat-generating wire 21 is used to transfer heat to the outer surface 12 of the light-transmitting cover 1. . Therefore, if the vehicle lampshade 10 is shielded by snow, freezing rain or hail in winter, the snow on the transparent cover body 1 can be quickly melted by the electric heating of the heat generating module 2, so that the light can be transmitted through the light. The cover 1 is fired to achieve a safe effect.

The light transmissive cover 1 further comprises an upright connection 13 for connecting the inner surface 11, the buckle 13 having, for example, a plurality of buckles (not shown) spaced apart from each other and a perforation (not shown) for the power supply conductor 24 to pass through. The buckle 13 and the transparent cover 1 shown in FIG. 1 and FIG. 3 are preferably integrally formed, wherein the material of the buckle 13 and the transparent cover 1 can be made of plastic, acrylic or other materials. . Each of the fastening portions of the embodiment is, for example, a single piece, which is fixed to the corresponding lamp holder (not shown) by plugging; however, in other different embodiments, each of the fastening portions may also be a plate with a hook or Other suitable structures are correspondingly fastened to the lamp holder. The power conductor 24 is a power lead, a conductive terminal or other suitable conductor, and is not limited.

Further, the material of the heat generating wire 21 is preferably an alloy wire and has a wire diameter of less than 100 μm. The material of the non-conductor film 22 is made of, for example, a resin resistant to high temperature or other suitable material. The number of the heating wires 21, the flexible circuit board 23, and the power supply conductor 24 are respectively two to distinguish two different polarities (ie, positive and negative). Each of the heat-generating wires 21 and the power supply conductors 24 as shown in FIG. 1 are preferably electrically connected to both ends of the flexible circuit board 23 by soldering. The non-conductor film 22 further has a protruding portion 221 corresponding to the flexible circuit board 23, so that the flexible circuit board 23 can be attached to the protruding portion 221.

The shape in which the heat generating wires 21 of the present embodiment are distributed, the shapes of the non-conductor film 22 and the light-transmitting cover 1 correspond to each other. Specifically, the shape in which the heat generating wires 21 are distributed, the shape of the non-conductive film 22 and the light-transmitting cover 1 are preferably each a circular shape. However, in other different embodiments, the shape of the heat-generating wires 21, the shape of the non-conductor film 22, and the transparent cover 1 may be a rectangular shape, an elliptical shape or other suitable shapes, respectively, and are not limited.

In summary, the embodiments disclosed herein are to be considered as illustrative of the present invention and are not intended to limit the present invention.
