Description

Technical Field

[0001] This application relates to the technical field of rearview mirrors, and in particular to an installation structure of a rearview mirror lens. Background Art

[0002] Due to the novel shape of the integrated exterior rearview mirror, as well as advantages such as reduced wind resistance, simplified assembly, and increased field of view, more and more vehicle manufacturers are currently adopting the design of integrated rearview mirrors. It combines the lens adjuster and the lens flipper on the traditional rearview mirror into one, and realizes these two functions through an electric motor.

[0003] Currently, the installation of the integrated rearview mirror lens requires pasting the lens on the mirror ring with tape, and then installing it through the installation structure between the mirror ring and the rearview mirror body. The installation process is complex and cumbersome, affecting the production rhythm; at the same time, there are many mating structures between sub-parts, and problems such as poor mating are likely to occur, resulting in the product quality being affected, thus causing complaints from vehicle manufacturers and purchasers. Summary of the Invention

[0004] The purpose of this application is to provide an installation structure of a rearview mirror lens.

[0005] To achieve the above object, the technical solution adopted in this application is: An installation structure of a rearview mirror lens is formed between a decorative cover and a secondary mirror housing that are fitted and installed. The decorative cover and the secondary mirror housing are respectively formed with a first limiting portion and a second limiting portion. The first limiting portion and the second limiting portion respectively limit the edges of the upper half and the lower half of the lens, so that the lens is fixedly installed. At least one contact site is respectively formed on the outer side and the inner side of the lens, and the lens is connected to the first limiting portion and the second limiting portion through the contact sites.

[0006] As a preference, both the first limiting portion and the second limiting portion include limiting grooves. The limiting grooves reduce the opening of the rearview mirror installation cavity formed by the cooperation of the decorative cover and the secondary mirror housing, and the distance between the two limiting grooves is equal to or greater than the distance between the upper and lower ends of the lens at the corresponding position.

[0007] Further preferably, a sealing gasket is arranged in the limiting groove. The sealing gasket is made of an elastic material; the edge of the lens is fixedly fitted with the sealing gasket.

[0008] As a preference, a drain hole and a bottom outlet are respectively arranged on the outer side and the bottom of the second limiting portion.

[0009] As a preference, a tape is arranged on the inner side of the lens. The tape is bonded to the inner side wall of the limiting groove; the tape includes bonding surfaces on both sides and a buffer portion in the middle. The buffer portion is made of a water-impermeable material.

[0010] As a preference, an arched mating surface is formed between the gasket and correspondingly the limiting groove, and the arch is in a broken line shape or an arc shape.

[0011] As a preference, drain holes are formed in the outer part of the second limiting part, and the top height of the drain holes is greater than or equal to the height of the top of the gasket.

[0012] As a preference, at least one fixing assembly is provided at the joint of the decorative cover and the auxiliary mirror housing. The fixing assembly includes a first fixing part and a second fixing part. The first fixing part and the second fixing part respectively include a fixing groove and a clamping part. During installation, the first fixing part and the second fixing part approach each other. Until the clamping part contacts the outer side surface of the fixing groove, the clamping part deforms and enters the fixing groove to form a fixation.

[0013] As a preference, inclined surfaces are provided on both outer sides of the clamping part, and the inner groove surface of the fixing groove is adapted to cooperate with the inclined surfaces formed on both sides of the clamping part.

[0014] As a preference, the auxiliary mirror housing forms a limiting sliding groove, and the decorative cover forms a limiting sliding block. When the first fixing part and the second fixing part start to approach, the limiting sliding block is located at the first end of the limiting sliding groove. After the first fixing part and the second fixing part are fixedly combined, the limiting sliding block is located at the second end of the limiting sliding groove.

[0015] Compared with the prior art, the beneficial effects of the present application are as follows:

[0016] The lens is connected to the first limiting part and the second limiting part through contact sites. The lens has a plurality of contact sites for restricting movement, which can increase the fixing effect on the lens. In order to ensure the sufficient fixation of the lens, at least one contact site is respectively formed on the outer side surface and the inner side surface of the lens, so that the lens cannot move towards both the inner and outer sides.

[0028] Embodiment 1:

[0029] Refer to Figures 1 to 6, this embodiment proposes a rearview mirror lens mounting structure, which is formed between the decorative cover 1 and the auxiliary mirror shell 2 that are mounted in conjunction with each other, and a bowl-shaped mounting portion 3 is formed in the middle of the bottom of the auxiliary mirror shell 2 for mounting the motor assembly. The decorative cover 1 and the auxiliary mirror shell 2 are respectively formed with a first limiting portion 4 and a second limiting portion 6, which respectively limit the edges of the upper half and the lower half of the lens 5 so that the lens 5 is fixedly mounted, and at least one contact point is formed on the outer side and the inner side of the lens 5, respectively, and the lens 5 is connected to the first limiting portion and the second limiting portion through the contact point. The lens 5 has multiple contact points for limiting movement, which can increase the fixing effect on the lens 5. In order to ensure that the lens 5 is fully fixed, at least one contact point is formed on the outer side and the inner side of the lens 5, respectively, so that the lens 5 cannot move inward or outward. It is worth mentioning that since the outer edge of the rearview mirror is a ring, and referring to Figure 2 As shown, the first and second limiting portions 4, 6 cooperate to form only two contact points, two on the top and two on the bottom. However, the decorative cover 1 and the secondary mirror housing 2 actually wrap around the edge of the lens 5. Therefore, several such contact points are also provided around the edge of the lens 5. All of these contact points together form a circular line around the edge of the lens 5. Rubber protrusions can also be provided at the contact points to increase friction between the first and second limiting portions 4, 6, and the lens 5.

[0030] Example 2:

[0031] Reference Figures 3 to 5 As shown, the first limiting portion 4 and the second limiting portion 6 both include limiting grooves, which reduce the opening of the rearview mirror installation cavity formed by the decorative cover 1 and the secondary mirror housing 2. The distance between the two limiting grooves is equal to or greater than the distance between the upper and lower ends of the lens 5 at the corresponding position. Figure 3 The corresponding grooves at the top and bottom of the middle lens 5, Figure 3 Without adhesive tape 8, the left side of the lens 5 contacts the left side of the limiting groove, and the right side of the lens 5 contacts the right side of the limiting groove, respectively, creating two contact points. Obviously, the lens 5 can be enlarged appropriately so that the top of the lens 5 abuts the innermost side of the limiting groove, thereby increasing the number of contact points. To ensure that the lens 5 has a certain cushioning capacity and can provide cushioning during bumps, the adhesive tape 8 can reduce the hard contact between the lens 5 and the inner wall of the limiting groove. Of course, the inner wall of the limiting groove can also be made of an elastic material, so that the lens 5 can be directly installed to achieve cushioning through the elastic deformation of the limiting groove itself.

[0032] Reference Figure 5, Further, a gasket 11 can be provided in the limiting groove. To ensure the convenience of installing the lens 5 and the sealing performance after installation, the gasket 11 is made of an elastic material; the edge of the lens 5 is fixedly engaged with the gasket 11.

[0033] As Figure 3 shown, when the gasket 11 is not provided, a drain hole 9 and a bottom outlet 10 are respectively provided on the outer side and the bottom of the second limiting portion 6. When the gasket 11 is not provided, the lens 5 is directly in contact with the limiting groove for installation, and at this time the sealing performance is relatively poor. Therefore, in order to prevent liquid accumulation and penetration at the connection, the drain hole 9 is provided at a relatively upper position, which can drain most of the liquid, and a small amount of liquid that enters the inside of the connection is discharged through the bottom outlet 10 at the bottom. In the design of the drain hole 9 and the bottom outlet 10, a funnel-shaped design can be adopted to prevent water from entering from the outside.

[0034] As Figure 3 , Figure 4 shown, in order to increase the sealing performance and stability after the lens 5 is installed, a tape 8 is provided on the inner side of the lens 5, and the tape 8 is bonded to the inner side wall of the limiting groove; the tape 8 includes bonding surfaces on both sides and a buffer portion in the middle, and the buffer portion is made of a water-impermeable material. The tape 8 can bond the lens 5 and the structure inside the rearview mirror. For example, it can be directly bonded to the decorative cover 1 and the secondary mirror housing 2.

[0035] Referring to Figure 4 shown, an arched mating surface is formed between the gasket 11 and the corresponding limiting groove, and the arch is in a zigzag or arc shape. Figure 4 The arched mating surface shown is in a zigzag shape, and the shape of the arc-shaped arched mating surface is similar, and the zigzag can be changed to a smooth curve transition. Such a setting can increase the mating area between the gasket 11 and the limiting groove, which is beneficial to form a stable fit and good sealing performance. Since the gasket 11 is made of an elastic material, such as rubber or silica gel, it has good deformation ability. Therefore, after the lens 5 is installed, it can be fitted through the deformation of the gasket 11 and fixed to the lens 5 in the limiting groove. To ensure a good fixing effect, an interface groove for fitting the lens 5 is preferably provided on the inner side of the gasket 11 to facilitate the fixing of the lens 5.

[0036] After the gasket 11 is provided, there is a large contact area between the gasket 11 and the limiting groove, and when the lens 5 is installed, the gasket 11 is extruded and deformed to closely adhere to the limiting groove, so the sealing performance is good. Therefore, as Figure 5As shown in the figure, if it is necessary to improve the drainage performance in this embodiment, drainage holes 9 can be provided only on the outer side of the second limiting part 6, and the top height of the drainage holes 99 is greater than or equal to the top height of the gasket 11. The purpose of setting the drainage holes 9 is, on the one hand, to prevent liquid from accumulating at the joint and causing penetration. On the other hand, when the drainage holes 9 drain water, the water near the lens 5 and the water near the drainage holes 9 are likely to form a continuous water flow, which can reduce some water droplets from adsorbing on the lens 5, thereby reducing to a certain extent the impact of raindrops on the view provided by the rearview mirror lens 5 in the case of rain or the like. In daily life, it often happens that raindrops adsorb on the lens 5, which generally affects the driver's observation of the vehicle conditions behind through the outer rearview mirror.

[0037] As Figure 6 shown, at least one fixing component 7 is provided at the joint of the decorative cover 1 and the auxiliary mirror housing 2, and preferably two can be provided. The fixing component 7 includes a first fixing part 13 and a second fixing part 16. The first fixing part 13 and the second fixing part 16 respectively include a fixing groove 14 and a clamping part 15. During installation, the first fixing part 13 and the second fixing part 16 approach each other until the clamping part 15 contacts the outer side of the fixing groove 14. Then, the clamping part 15 deforms and enters the fixing groove 14 to form a fixation. Further, inclined surfaces are provided on both outer sides of the clamping part 15, and the inner groove surface of the fixing groove 14 is adapted to cooperate with the inclined surfaces formed on both sides of the clamping part 15. When the decorative cover 1 and the auxiliary mirror housing 2 are assembled close to each other, through the guidance of the inclined surfaces, the clamping part 15 first deforms and enters the fixing groove 14 to form a fixation. Obviously, in order to facilitate subsequent disassembly, inclined surfaces are provided in both the installation and disassembly directions of the clamping part 15. After the clamping part 15 and the fixing groove 14 are engaged, an external force needs to reach the level that causes the clamping part 15 to deform and disengage before the decorative cover 1 and the auxiliary mirror housing 2 can be separated.

[0038] To facilitate the installation of the decorative cover 1 and the auxiliary mirror housing 2, the auxiliary mirror housing 2 forms a limiting sliding groove 12, and the decorative cover 1 forms a limiting sliding block. When the first fixing part 13 and the second fixing part 16 start to approach, the limiting sliding block is located at the first end of the limiting sliding groove 12. When the first fixing part 13 and the second fixing part 16 are engaged and fixed, the limiting sliding block is located at the second end of the limiting sliding groove 12. During the initial assembly, through the cooperation and restriction of the limiting sliding groove 12 and the limiting sliding block, it is convenient to initially position the two, and then they are fixed through the cooperation of the clamping part 15 and the fixing groove 14, thus facilitating the installation process.
