Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to an installation structure for a concealed door handle for automobiles. Background Technology

[0002] With the development trend of intelligent and electric vehicles, concealed door handles are being used more and more widely in automobiles. Concealed door handles can reduce wind resistance, reduce fuel consumption, and enhance aesthetics and a sense of technology. When the door is not needed, the door handle is embedded in the outer door panel, flush with the surface of the outer door panel.

[0003] However, existing door handles have the following drawbacks: a car door consists of an inner door sheet metal (inner door) and an outer door panel (outer door). The door handle is positioned and connected through the inner door sheet metal, and the outer door panel is connected to the inner door panel. There are assembly errors between the inner and outer doors, and there are also assembly errors between the door handle and the inner door. Furthermore, the inner door, outer door, and door handle all have dimensional tolerances during manufacturing. These dimensional tolerances accumulate and manifest in the relative positions of the outer door and the door handle, causing the door handle to not be flush with the outer door after being assembled on the inner door, thus losing the function of a concealed door handle. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to propose an installation structure for a hidden door handle for automobiles, so as to solve the problem that the door handle cannot be flush with the outer door in the prior art.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] Furthermore, the positioning part includes a boss protruding from the surface of the door handle.

[0007] Furthermore, the door handle is provided with multiple positioning parts, which are arranged along the edge of the door handle.

[0008] Furthermore, the door handle is equipped with pre-installed claws for engaging with the interior door of the vehicle.

[0009] Furthermore, the door handle has a mounting surface facing the inner door, and there is a reserved gap between the mounting surface and the inner door, and the mounting part is disposed on the mounting surface.

[0010] Furthermore, the mounting surface has a deformable portion and an abutting portion. One end of the deformable portion is connected to the door handle, and the other end is connected to the abutting portion. The wall thickness of the deformable portion is less than the wall thickness of the abutting portion.

[0011] Furthermore, the door handle is also provided with a limiting block, and the deformation of the deformable part causes the abutting part to abut against both the limiting block and the inner door simultaneously.

[0012] Furthermore, the mounting part is connected to the inner door bolt.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] (1) The door handle has a positioning part and an installation part. The installation part is still connected to the inner door, while the positioning part abuts against the outer door, so that the door handle and the outer door can be positioned by the positioning part, thereby keeping the door handle flush with the surface of the outer door and improving the quality of the joint between the door handle and the outer door.

[0015] (2) A certain reserved gap is provided between the mounting surface and the inner door, and the mounting surface has a deformable part. During installation, a certain deformation is generated by the deformable part, causing the abutting part to move towards the inner door, eliminating the reserved gap and realizing assembly. That is, by reserving a gap and by deforming the deformable part, this application ensures that the abutting part is always in contact with the inner door after assembly, thereby eliminating assembly errors and manufacturing tolerances between the door handle and the inner door.

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] Please refer to Figures 1-5This invention discloses an installation structure for a hidden door handle for automobiles, used to install the door handle 200 on the inner door 300 of an automobile. When the door handle 200 is hidden, the outer surface of the door handle 200 is flush with the surface of the outer door 100 of the automobile. The door handle 200 is provided with a positioning part 220 and an installation part 210. The positioning part 220 abuts against the outer door 100 of the automobile, and the installation part 210 is connected to the inner door 300 of the automobile.

[0027] Specifically, the door handle 200 of this application has a positioning part 220 and an installation part 210. The installation part 210 is still connected to the inner door 300, while the positioning part 220 abuts against the outer door 100, so that the door handle 200 and the outer door 100 can be positioned by the positioning part 220, thereby keeping the door handle 200 flush with the surface of the outer door 100 and improving the quality of the joint between the door handle 200 and the outer door 100.

[0028] Furthermore, the positioning part 220 includes a boss protruding from the surface of the door handle 200.

[0029] Furthermore, the boss is made of hard plastic.

[0030] By having the protrusion on the door handle 200 abut against the outer door 100, the distance between the base of the door handle 200 and the outer door 100 in the thickness direction is always consistent, thereby making the surface of the door handle 200 flush with the surface of the outer door 100.

[0031] The thickness of the boss can be adjusted by reducing or increasing the amount of hard rubber on the boss, thereby adjusting the distance from the base of the door handle 200 to the outer door 100 in the thickness direction, so as to be compatible with different types of car doors and door handles 200.

[0032] Furthermore, the door handle 200 is provided with a plurality of positioning parts 220, which are arranged along the edge of the door handle 200.

[0033] Multiple protrusions are arranged along the edge of the door handle 200, and the multiple protrusions simultaneously abut against the inner wall of the outer door 100, so that the force on the door handle 200 is more even at all positions.

[0034] Furthermore, the door handle 200 is provided with a pre-installed claw for engaging with the interior door 300 of the vehicle.

[0035] The door handle 200 is pre-installed with a locking claw. Before assembly, the door handle 200 can be locked onto the inner door 300 using the pre-installed locking claw. Then, the connecting part is connected to the inner door 300 to prevent the door handle 200 from falling off when the connecting part is connected, thus reducing the difficulty of assembly.

[0036] Furthermore, the door handle 200 has a mounting surface facing the inner door 300, and there is a reserved gap between the mounting surface and the inner door 300, and the mounting part 210 is disposed on the mounting surface.

[0037] Furthermore, the mounting surface has a deformable portion 230 and an abutting portion 240. One end of the deformable portion 230 is connected to the door handle 200, and the other end is connected to the abutting portion 240. The wall thickness of the deformable portion 230 is less than the wall thickness of the abutting portion 240.

[0038] It should be noted that during assembly, there may be errors between the inner door 300 and the door handle 200, which may cause the mounting surface of the door handle 200 to be mismatched with the inner door 300, thus making assembly impossible.

[0039] Based on this, this application provides a certain reserved gap between the mounting surface and the inner door 300, and the mounting surface has a deformable part 230. During installation, the deformable part 230 deforms, causing the abutment part 240 to move towards the inner door 300, eliminating the reserved gap and achieving assembly. That is, by providing a reserved gap and by deforming the deformable part 230, this application ensures that the abutment part 240 remains in contact with the inner door 300 after assembly, thereby eliminating assembly errors and manufacturing tolerances between the door handle 200 and the inner door 300.

[0040] Furthermore, the door handle 200 is also provided with a limiting block 250, and the deformation part 230 deforms so that the abutting part 240 abuts against the limiting block 250 and the inner door 300 at the same time.

[0041] It should be noted that when the error between the inner door 300 and the door handle 200 is too large, even if the deformation part 230 undergoes maximum deformation, it will not be able to assemble the mounting part 210 with the inner door 300 properly. In this case, the deformation part 230 is prone to excessive deformation and damage.

[0042] Based on this, a limiting block 250 is set. After the deformable part 230 begins to deform, the abutting part 240 gradually moves toward the limiting block 250 and the inner door 300.

[0043] like Figure 4 As shown, when the error between the inner door 300 and the door handle 200 is within the allowable range, after assembly, the abutment part 240 will abut against the inner door 300, or abut against the inner door 300 and the limit block 250 simultaneously.

[0044] like Figure 5 As shown, when the error between the inner door 300 and the door handle 200 exceeds the allowable range, as the deformable part 230 deforms, the abutting part 240 first abuts against the limiting block 250 to prevent the deformable part 230 from continuing to deform and causing damage.

[0045] Furthermore, the mounting part 210 is bolted to the inner door 300.

[0046] More specifically, the deformation part 230 can be caused by tightening the bolts of the mounting part 210. As the mounting part 210 is tightened, the deformation part 230 gradually deforms until it is tightened to the inner door 300, at which point the deformation part 230 stops deforming. In other words, by minimizing the deformation of the deformation part 230 while ensuring that the mounting part 210 can be tightened to the inner door 300, excessive deformation of the deformation part 230 can be effectively avoided, thus preventing damage.

[0047] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0048] Furthermore, in this invention, descriptions involving terms such as "first," "second," and "a" are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0049] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0050] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
