Description

Technical Field

[0001] The utility model relates to the technical field of vehicle rearview mirrors, in particular to a mounting structure for a decorative cover of a vehicle rearview mirror. Background Art

[0002] Automobile rearview mirrors usually include components such as a mirror housing, a mirror ring, a lens, a steering gear, a substrate, a support plate, and a bracket. The exterior rearview mirror is fixed to the front door by a bracket. The mirror housing is generally divided into an upper mirror housing (also known as a decorative cover) and a lower mirror housing. First, the lower mirror housing is installed, then the substrate, the steering gear, the mirror ring, etc. are installed, and finally the decorative cover is installed on the lower mirror housing or the mirror ring to cover other parts inside. Side turn signals are provided on the exterior rearview mirror of the vehicle, and the side turn signal is located between the decorative cover and the lower mirror housing. The decorative cover is also connected to the turn signal housing. The lower mirror housing or the mirror ring or the side turn signal housing for installing the decorative cover can be collectively referred to as a counter part.

[0003] Currently, the mounting structure of the decorative cover is as Figure 1 shown. A limiting structure (limiting rib) and a mounting (snap) structure are provided on the decorative cover and the counter part. As can be seen in the figure, a snap and a limiting groove are respectively provided on the decorative cover, and a snap hole and a limiting rib are provided on the counter part. The limiting function is realized by using the limiting rib and the groove, and the connection and installation are carried out by using the snap structure. The limiting structure and the mounting structure are independent of each other and jointly realize the assembly of the decorative cover.

[0004] The decorative cover and the counter part of the vehicle rearview mirror are usually injection molded. If the injection molded product is deformed, the limiting structure and the mounting structure of the decorative cover cannot exactly coincide with the structures on the counter part at the same time, which brings difficulties to the assembly process. In addition, the installation and limiting structures are respectively provided, and the structures of the decorative cover and the counter part as injection molded parts are more complex, occupying more space inside the vehicle rearview mirror housing, and are not applicable to all vehicle models. Moreover, the limiting rib is easily damaged during assembly. Summary of the Utility Model

[0005] Aiming at the above-mentioned shortcomings or deficiencies of the prior art, the technical problem to be solved by the utility model is to combine the limiting structure and the mounting structure of the decorative cover into one, so that the assembly is smoother and the structure is simpler.

[0006] To solve the above technical problem, the utility model has the following constitution:

[0007] The installation structure of the decorative cover of an automotive rearview mirror has one or more buckles protruding from the inner wall surface of the decorative cover. Each buckle is fitted with a corresponding U-shaped card on the mating part of the automotive rearview mirror. The front end of the buckle has an elastic upper tongue and a lower hook claw. The U-shaped card has an upper lintel and a lower boss. When installing the decorative cover, the decorative cover is pushed downward. The lower hook claw enters the U-shaped card, and the upper tongue is elastically deformed under extrusion. After assembly, the upper tongue rebounds and makes pressure contact with the upper lintel, and the lower boss prevents the lower hook claw from slipping outwards. There is no gap between the buckle and the U-shaped card, and the decorative cover is installed on the mating part.

[0008] The materials of the decorative cover and the mating part are ABS plastics. The buckle and the decorative cover are integrally formed by injection molding, and the U-shaped card and the mating part are integrally formed by injection molding. A space is left between the upper tongue and the lower hook claw, and the inside of the buckle is set as a cavity.

[0009] The lower hook claw is chamfered towards the contact surface side, and the contact surfaces of the lower hook claw of the buckle and the lower boss are inclined surfaces that slope towards the decorative cover.

[0010] Two reinforcing ribs are provided between the two side edges of the U-shaped card on the non-working side of the U-shaped card and the mating part body.

[0011] Compared with the prior art, the advantages of the present utility model are as follows:

[0012] There is only a pair of assembly structures, namely the buckle and the U-shaped card, between the decorative cover and the mating part of the present utility model, which makes the assembly process easier to implement. And because the buckle and the U-shaped card have two pairs of upper and lower positioning pairs and there is no gap during installation, there is no height difference on the surfaces of the decorative cover and the mating part after assembly, and the assembly effect is better, ensuring that the outer surface of the rearview mirror meets the design requirements. The pair of assembly structures of the buckle and the U-shaped card combines the functions of a limiting structure and an installation structure, simplifies the installation structure of the decorative cover, and occupies less internal space of the rearview mirror housing. Neither the buckle nor the U-shaped card is a thin-walled structure, and they have high strength and are not easily damaged during the installation process.

[0013] The materials of the decorative cover and the mating part are ABS plastics and are integrally formed with the installation structure. The processing technology is simpler, and the ABS plastic has a certain elasticity, meeting the material requirements for the buckle to deform slightly.

[0014] A space is left between the upper tongue and the lower hook claw of the buckle, and the inside of the buckle is set as a cavity. In addition, the lower hook claw is chamfered towards the contact surface side, and the contact surfaces of the lower hook claw of the buckle and the lower boss are inclined surfaces that slope towards the decorative cover. All the above structural designs can make the disassembly of the decorative cover smoother and optimize the assembly process. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The mounting structure of the decorative cover of the vehicle rearview mirror of the present utility model is provided with a snap fastener 2 with a special structure on the decorative cover 1, and a door-shaped card 4 is provided on the counterpart 3. The structure of the snap fastener 2 has both the functions of limiting and installing, which is convenient for the assembly of the decorative cover 1 and ensures that the outer surface of the rearview mirror is smooth without height difference, meeting the design requirements.

[0025] See Embodiment 1 Figures 2 to 4 , one or more snap fasteners 2 are protrudingly provided on the inner wall surface of the decorative cover 1, and each snap fastener 2 is cooperatively installed with a door-shaped card 4 correspondingly provided on the counterpart 3 on the rearview mirror. The front end of the snap fastener 2 is an elastic upper tongue 2a and a lower hook 2b. The door-shaped card 4 has an upper lintel 4a and a lower boss 4b. When installing the decorative cover 1, the decorative cover 1 is pushed downward ( Figure 2 ), the lower hook 2b enters the door-shaped card 4, and the upper tongue 2a is elastically deformed under extrusion. After the assembly is completed, from Figure 4As can be seen from the cross-sectional view, the upper latch tongue 2a rebounds and comes into pressure contact with the upper door lintel 4a, the lower boss 4b prevents the lower hook 2b from falling out, the door-shaped card 4 limits the position of the decorative cover from different directions through the buckle 2, there is no gap between the buckle 2 and the door-shaped card 4, the decorative cover is accurately positioned, and the decorative cover is installed on the opponent part 3.

[0026] There is only one pair of assembly structures, namely, the buckle 2 and the door-shaped card 4, between the decorative cover 1 and the pair of the hand piece 3 of the utility model, which is more convenient to implement the assembly process, and there is no situation where the separated positioning structure and the installation structure cannot be smoothly positioned at the same time due to the deformation of the parts. Moreover, because the buckle 2 and the door-shaped card 4 have two pairs of upper and lower positioning pairs, there is no gap in the installation, so there is no height difference between the decorative cover 1 and the surface of the hand piece 3 after assembly, and the assembly effect is better, ensuring that the outer surface of the rearview mirror meets the design requirements. In addition, the buckle 2 and the door-shaped card 4 are a pair of assembly structures, which have the functions of the limiting structure and the installation structure, and the installation structure of the decorative cover 1 is simplified, occupying less internal space of the rearview mirror housing. Furthermore, the buckle 2 and the door-shaped card 4 are not thin-walled structures, with high strength, and are not easily damaged during the installation process.

[0027] Embodiment 2

[0028] The decorative cover 1 and the pair of pieces 3 of the first embodiment are made of ABS plastic (thermoplastic polymer material), the buckle 2 and the decorative cover 1 are integrally formed by injection molding, and the door-shaped card 4 and the pair of pieces 3 are also integrally formed by injection molding. The processing technology of integral molding is simpler, and the ABS plastic has a certain elasticity, which just meets the material requirement that the buckle 2 needs to be slightly deformed. Furthermore, a space is left between the upper tongue 2a and the lower hook 2b of the buckle 2, and the inside of the buckle 2 is set as a cavity. This is more conducive to the elastic deformation of the front end of the buckle 2, and the installation of the buckle 2 is smoother.

[0029] The lower hook claw 2b of embodiments one and two is chamfered toward the contact surface side, and the contact surface between the lower hook claw 2b of the buckle 2 and the lower boss 4b is an inclined surface inclined toward the decorative cover. The chamfer makes it easier for the lower hook claw 2b to enter the door-type card 4 from the beginning, and the inclined surface can disperse the resistance so that the lower hook claw 2b gradually enters the installation position. The inclined surface and chamfer settings make it smoother to remove the decorative cover 1.

[0030] On the basis of the first embodiment, two reinforcing ribs are arranged between the two side edges of the door shape of the non-working side of the door-shaped card 4 and the main body of the opponent 3 to further enhance the structural strength of the door-shaped card 4 .

[0031] It can be seen from the above embodiments that the decorative cover mounting structure of the automobile rearview mirror of the utility model has the advantages of smoother assembly process and better assembly effect, and the mounting structure has high strength and occupies a small internal space.

[0032] The above embodiments are only used to illustrate the present utility model, rather than to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent substitutions of the technical solutions of the present utility model do not depart from the spirit and scope of the technical solutions of the present utility model, and should all be covered within the scope of the claims of the present utility model.
