Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to an integrated rearview mirror lens mounting structure. Background Technology

[0002] Rearview mirrors are safety components installed on the left and right sides and the front interior of a vehicle. They are important vehicle safety parts, and their quality and installation must meet industry standards and specifications. They expand the driver's field of vision by reflecting the road conditions behind, to the sides, and below the vehicle. Based on their installation location, they are divided into exterior rearview mirrors and interior rearview mirrors. Interior rearview mirrors mostly use plane mirrors to provide a proportional image, while exterior rearview mirrors use convex mirrors to expand the field of vision.

[0003] Existing integrated rearview mirrors typically use bolts to mount the lens assembly to the mirror housing. While this connection method is secure, the bolts may loosen or rust over time, affecting subsequent disassembly and assembly. Therefore, an integrated rearview mirror lens mounting structure is proposed to solve the aforementioned technical problems. Utility Model Content

[0004] One of the objectives of this application is to provide an integrated rearview mirror lens mounting structure.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: an integrated rearview mirror lens mounting structure, including a mirror housing and a lens part. The mirror housing includes an upper housing and a lower housing. The lower housing is made by two-color injection molding and includes a hard rubber part and a soft rubber part. The soft rubber part is connected to the actuator. The upper housing and the lower housing are connected by a snap-fit ​​structure. The lens part is also connected to the upper housing and the lower housing by a snap-fit ​​structure.

[0006] Preferably, the snap-fit ​​structure includes a snap hook and a snap block; during installation, the snap hook is adapted to move and deform along the wedge-shaped surface of the snap block, and then the snap hook is adapted to cross the wedge-shaped surface and engage with the snap block.

[0007] Preferably, the exterior of the mirror housing is provided with a plurality of unlocking holes that cooperate with the buckle structure; during disassembly, the hook is adapted to be forcibly separated from the buckle through the unlocking holes.

[0008] Preferably, a connecting rod assembly is provided at the bottom end of the lens housing, and a blind spot mirror is installed at the end of the connecting rod assembly; in use, the connecting rod assembly is adapted to unfold so that the blind spot mirror cooperates with the lens part; when not in use, the connecting rod assembly is adapted to fold so that the blind spot mirror is stored at the bottom end of the lens housing.

[0009] Preferably, the linkage assembly includes a rod seat and a movable rod. The rod seat is installed at the bottom end of the lens housing and has a groove at its first end. The second end of the rod seat is rotatably connected to the first end of the movable rod, and the second end of the movable rod is connected to the blind spot lens. In use, the movable rod is adapted to rotate until it abuts against the lens portion. When not in use, the movable rod is adapted to reverse until the blind spot lens is stored in the groove.

[0010] Preferably, the linkage assembly further includes an inner rod, which is telescopically slidably disposed at the second end of the rod seat and rotatably connected to the first end of the moving rod.

[0011] Preferably, a suction cup is provided on the side of the movable rod away from the blind spot mirror; in use, the movable rod is adapted to cooperate with the lens part through the suction cup.

[0012] Preferably, the blind spot mirror and the moving rod are connected by a ball joint, thereby enabling the angle adjustment of the blind spot mirror within a set range.

[0013] Compared with the prior art, the beneficial effects of this application are as follows: This utility model divides the rearview mirror into three parts: an upper housing, a lower housing, and a lens. The two adjacent parts can be quickly assembled using a snap-fit ​​structure, resulting in high installation efficiency. In addition, the lower housing is made of two-color injection molding. The hard plastic part serves as a small part of the bottom appearance of the lens, while the soft plastic part has a lip for sealing with the actuator. In other words, the two-color lower housing serves as both an appearance part and a seal, eliminating the need for an additional sealing gasket and making the seal more stable.

Detailed Implementation

[0023] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0025] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0026] One preferred embodiment of this application, such as Figures 1 to 8 As shown, an integrated rearview mirror lens mounting structure includes a mirror housing 1 and a lens part 2. The mirror housing 1 includes an upper housing 101 and a lower housing 102. The lower housing 102 is made by two-color injection molding and includes a hard plastic part 1022 and a soft plastic part 1021. The soft plastic part 1021 is connected to the actuator. The upper housing 101 and the lower housing 102 are connected by a snap-fit ​​structure 4. The lens part 2 is also connected to the upper housing 101 and the lower housing 102 by the snap-fit ​​structure 4.

[0027] It is understandable that the entire rearview mirror is assembled in three parts: the upper housing 101, the lower housing 102, and the lens part 2. The two adjacent parts can be quickly assembled through the snap-fit ​​structure 4, which makes the installation efficient.

[0028] Additionally, the lower housing 102 uses a two-color material, i.e., two-color injection molding: two different colored plastics are injected into a mold to form a composite plastic product. It includes a soft plastic part 1021 and a hard plastic part 1022. The hard plastic part 1022 forms a small portion of the bottom appearance of the lens, such as... Figure 2 As shown, its soft rubber part 1021 has a lip for sealing with the actuator (e.g., motor ball cup). In other words, the two-tone lower housing 102 serves as both an exterior component and a seal, eliminating the need for additional sealing gaskets and resulting in a more stable seal. It should be noted that how the existing rearview mirror lower housing 102 is installed with the actuator via the mating of sealing gaskets is common knowledge to those skilled in the art and will not be described in detail here.

[0029] As a further description of the above embodiments: as Figure 2 and Figure 3 As shown, the snap-fit ​​structure 4 includes a hook 401 and a locking block 402. For example: Figure 3 As shown in the upper figure, the lens part 2 is installed with the lower housing 102. At this time, the hook 401 on the lens part 2 is engaged with the locking block 402 on the lower housing 102. When the hook 401 engages with the locking block 402, the hook 401 moves and deforms along the wedge-shaped surface of the locking block 402. After the hook 401 crosses the wedge-shaped surface, it returns to its original shape and engages with the locking block 402, thus achieving rapid assembly of the two components. Figure 3 The image below is shown.

[0030] Further optimization, such as Figure 3 As shown, the snap-fit ​​structure 4 also includes a snap-fit ​​post 403 and a snap-fit ​​groove 404. Taking the installation of the lens part 2 and the lower housing 102 as an example, when the two are engaged, the snap-fit ​​post 403 on the lens part 2 will then engage with the snap-fit ​​groove 404 on the lower housing 102, which can further enhance the stability of the connection between the lens part 2 and the lower housing 102 and effectively prevent loosening during use.

[0031] Further optimization, such as Figure 3As shown, at least one unlocking hole 5 is provided on the outside of the housing to cooperate with the snap-fit ​​structure 4; for example, the unlocking hole 5 is located on the outside of the lower housing 102 corresponding to the snap-fit ​​block 402; when the snap hook 401 and the snap-fit ​​block 402 are engaged, if they are forcibly demolded, the snap hook 401 is easily deformed and damaged. However, by setting the unlocking hole 5, we can use a rod to pass through the unlocking hole 5 and push the snap hook 401 upward to forcibly separate it from the snap-fit ​​block 402. This design makes it easy to separate the snap hook 401 from the snap-fit ​​block 402 when disassembly or maintenance is required, without damaging the snap hook 401, which greatly improves the maintainability and service life of the product. It should be noted that, for example, if we detach the snap-fit ​​structure 4 at the bottom of the lens part 2 and then disassemble the lens part 2, the interior of the rearview mirror is essentially opened, so the other snap-fit ​​structures 4 can be easily disassembled. Therefore, the unlocking hole 5 is preferably located at the bottom of the rearview mirror, so as not to affect its appearance.

[0032] In one embodiment of this application, such as Figure 1 and Figure 4 As shown, a connecting rod assembly 6 is provided at the bottom of the lens housing 1, and a blind spot mirror 3 is installed at the end of the connecting rod assembly 6. It can be understood that when in use, the connecting rod assembly 6 can be unfolded so that the blind spot mirror 3 can cooperate with the lens part 2; when not in use, the connecting rod assembly 6 can be folded so that the blind spot mirror 3 can be stored at the bottom of the lens housing 1.

[0033] It should be noted that the blind spot mirror 3 (also known as a small round mirror) is an auxiliary device added to the exterior rearview mirror of a car, mainly used to expand the driver's field of vision and reduce blind spots. Existing blind spot mirrors 3 are generally adhesive-mounted and primarily used when reversing to help observe the position of the rear wheels and avoid scraping obstacles. However, during normal driving, the blind spot mirror 3 may obstruct part of the rearview mirror's view. The above embodiment allows for the retraction of the blind spot mirror 3, greatly improving convenience.

[0034] As a further description of the above embodiments: as Figure 4 As shown, the linkage assembly 6 includes a rod seat 601 and a moving rod 603. The rod seat 601 is installed at the bottom of the mirror housing 1 and a groove 7 is provided at the first end. The second end of the rod seat 601 is rotatably connected to the first end of the moving rod 603, and the second end of the moving rod 603 is connected to the blind spot mirror 3.

[0035] Understandably, during use, the lever 603 can be rotated until it abuts against the lens section 2. Of course, the lever 603 can be limited by a damping pivot to limit the blind spot lens 3 after it has been adjusted to the appropriate position. When not in use, the lever 603 can be reversed until the blind spot lens 3 is securely received in the slot 7. At this time, the slot 7 can also protect the blind spot lens 3.

[0036] Based on the above embodiments, the following problems may exist during use: In order for the movable rod 603 to be rotated, stored and unfolded better, the second end (i.e. the right end) of the rod seat 601 needs to pass over the rearview mirror so that the rotation of the movable rod 603 will not interfere. However, when retracted, the protruding rod seat 601 will affect the overall aesthetics.

[0037] Therefore, in order to solve the above-mentioned technical problems, in this embodiment, as follows: Figure 5 As shown, the linkage assembly 6 also includes an inner rod 602, which is telescopically slidably disposed at the second end of the rod seat 601 and rotatably connected to the first end of the movable rod 603. During retraction, after the movable rod 603 is rotated downward, the inner rod 602 is retracted into the rod seat 601, so that the entire linkage assembly 6 after retraction is located at the bottom of the rearview mirror.

[0038] Further preferably, a suction cup 9 is provided on the side of the movable rod 603 away from the blind spot mirror 3. That is to say, during use, the movable rod 603 can cooperate with the lens part 2 through the suction cup 9, so that the blind spot mirror 3 is more stable during use and the shaking caused by vehicle driving bumps is reduced.

[0039] Further optimization is that the blind spot mirror 3 and the moving rod 603 can be connected by a ball joint, which allows the angle of the blind spot mirror 3 to be adjusted within a set range, improving the flexibility of use.

[0040] The specific deployment and retraction working principle of the blind spot mirror 3 is as follows: like Figure 5 As shown, this is the state when the blind spot mirror 3 is unfolded and in use. The suction cup 9 is attached to the lens part 2, and the blind spot mirror 3 can also be adjusted in angle via the ball joint. When retracting, as... Figure 6 As shown, the suction cup 9 is separated from the lens section 2, and then the blind spot mirror 3 is moved downwards by rotating it clockwise via the moving rod 603; as shown Figure 7 As shown, the inner rod 602 is then slid to the left and retracted into the rod seat 601; as Figure 8 As shown, the blind spot mirror 3 is finally rotated clockwise via the moving rod 603 until it is locked into the groove 7 and retracted. Figure 5 As shown, a magnetic suction part 8 can also be provided at the bottom of the rod base 601. When the moving rod 603 is rotated and stored, it will abut against the magnetic suction part 8. The magnetic suction part 8 will attract and limit the moving rod 603, further improving the stability during storage.

[0041] Finally, it's worth noting that the entire Blind Spot Mirror 3 structure can be easily attached to the bottom of the rearview mirror using the bracket 601, without requiring complex modifications or damage to the original structure of the rearview mirror itself. This design preserves the integrity of the rearview mirror while adding the practical function of the Blind Spot Mirror 3, greatly improving driving safety and convenience. In other words, the Blind Spot Mirror 3 structure can be designed as a separate module or product, tailored to different rearview mirror models to adapt to the diverse range of car rearview mirrors on the market.
