[0001] The present application relates to the technical field of automobile door handle heating, and in particular to a hidden automobile door handle with a deicing function. Background Art

[0002] With the improvement of automobile manufacturing technology, the appearance design of automobiles is becoming more and more important. Therefore, hidden door handles are gradually appearing on new energy vehicles and even fuel vehicles. Compared with traditional car door handles, the design of hidden door handles makes the car look simpler and more beautiful. During driving, the hidden door handles can reduce wind resistance and save energy.

[0003] In cold weather, the water vapor that may exist in the car's hidden door handles may condense into ice, and frost will adhere to the door handles. The hidden door handles are more likely to be frozen. When they need to be activated, the hidden door handles cannot pop out, which can easily damage the internal telescopic structure. Utility Model Content

[0012] Optionally, a protective film is glued to the mounting groove, and the protective film is wrapped around the outer circumferential side wall of the door handle and covered outside the heating copper belt.

[0013] By adopting the above technical solution, after the heating component is installed, a gap will be generated between the heating component and the door handle. By providing a protective film, the gap and the heating component will be covered, so that the door handle is formed in one piece, preventing the operator from directly touching the heating component when touching the edge of the door handle, affecting the tactile feel and causing discomfort.

[0014] Optionally, glue is evenly applied to a side of the mounting groove close to the PI carrier film, and the PI carrier film is detachably connected to the door handle via the glue.

[0015] By adopting the above technical solution, the door handle is glued in the installation groove, which makes it convenient to replace the heating component. When replacing, you only need to remove the protective film and tear off the PI carrier film, and then replace and maintain the heating component.

[0016] Optionally, two opposite surfaces of the heating copper strip are provided with injection molds made of the same material as the door handle, and the two injection films are sleeved on the outside of the heating copper strip.

[0017] By adopting the above technical solution, the injection film is set to the same material as the door handle, which makes it easy to embed the heating component into the door handle and facilitates subsequent injection molding.

[0018] Optionally, a plurality of injection holes disposed opposite to each other are provided on the two injection films, and every two injection holes disposed opposite to each other are hollowed out and communicate with each other.

[0019] By adopting the above technical solution, the hollow injection hole facilitates the flow of injection liquid when the heating component is embedded in the door handle, so that after injection molding, the injection film and the heating copper strip fit tightly with the door handle.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. By arranging a PI carrier film, a heating copper belt, a hot melt adhesive layer and glue, and placing the PI carrier film and the heating copper belt on the side wall of the door handle, the heating copper belt is energized to generate heat, so that the heat generated by the heating copper belt is directly transferred to the place prone to ice formation, thereby reducing the possibility of ice formation on the door handle and reducing heat loss during heat transfer. After solidification, the hot melt adhesive fixes the heating copper belt on the PI carrier film, which is conducive to limiting and fixing the heating copper belt. The PI carrier film and the door handle are detachably connected by glue, which is convenient for replacement;

[0022] 2. By opening a hollow injection hole on the injection film, when the injection film and the heating copper belt are embedded in the door handle, it is convenient for the injection liquid to flow through the injection film, so that after injection molding, the injection film and the heating copper belt are closely fitted to the door handle, and the appearance is simple and exquisite; BRIEF DESCRIPTION OF THE DRAWINGS

A protective film 6 is wound and glued on the outer side of the circumferential side wall of the door handle 3, and the protective film 6 covers the outside of the heating component.

[0031] Reference Figure 2 , Figure 3 and Figure 4 The heating component includes a heating copper belt 2, which is arranged in a U-shaped belt shape. Both ends of the U-shape of the heating copper belt 2 are welded with energized wires (not shown in the figure). In order to better transfer heat, the two opposite sides of the heating copper belt 2 are coated with PI carrier films 1. The two PI carrier films 1 are in contact with the inner wall of the mounting groove 5 and slide with the mounting groove 5. The heating copper belt 2 and the two PI carrier films 1 are connected by a connecting piece. The connecting piece includes a hot melt adhesive layer 4. The hot melt adhesive layer 4 is evenly laid on the side of the two PI carrier films 1 close to the heating copper belt 2, and the hot melt adhesive layer 4 is coated on the outside of the heating copper belt 2.

[0032] Reference Figure 2 , Figure 3 and Figure 4 When the heating copper strip 2 is coated and connected with the PI carrier film 1, the hot melt adhesive layer 4 needs to be heated, and the hot melt adhesive layer 4 is melted and solidified to achieve a fixed connection between the heating copper strip 2 and the PI carrier film 1. In order to connect the heating component to the door handle 3, the side of the installation groove 5 close to the PI carrier film 1 is evenly coated with glue 7, and the PI carrier film 1 is detachably connected to the door handle 3 through the glue 7.

[0033] The implementation principle of a hidden door handle 3 deicing device in the embodiment of the present application is as follows: the heating copper strip 2 is connected to the PI carrier film 1 by heat-coating through the hot-melt adhesive layer 4, the hot-melt adhesive layer 4 is melted by heat and solidified, the heating copper strip 2 and the PI carrier film 1 are heat-coated, and the glue 7 is evenly applied on one side of the PI carrier film 1, the PI carrier film 1 and the heating copper strip 2 are wound in the installation groove 5, and a protective film 6 is glued to the outer side of the PI carrier film 1 and covered on the outer side of the door handle 3;
