Description

Technical Field

[0001] This invention relates to the field of interior rearview mirror protective cover technology, specifically to an interior rearview mirror protective cover with an embedded dashcam and its assembly method. Background Technology

[0002] In modern car driving scenarios, the rearview mirror is a key auxiliary device to ensure driving safety and plays a crucial role. It provides drivers with key visual information of the area behind and to the side of the vehicle in real time, helping them to accurately perform operations such as lane changing and reversing. At the same time, the rearview mirror is also indispensable for drivers to maintain spatial awareness and form an overall judgment of road conditions while driving.

[0003] However, the rearview mirrors of most vehicles on the market are directly exposed to the interior environment. This design poses many potential threats during daily use, especially in family car scenarios. If there are children in the car, their active nature makes their activities in the car highly random and unpredictable. Children are very likely to collide with the rearview mirror while playing and moving around in the car. Once the rearview mirror is bumped or knocked, even if it only develops a small crack, the continuous vibration caused by road bumps during driving will cause the crack to expand rapidly, and may even cause the lens to detach. This not only seriously affects the normal use of the rearview mirror, but also distracts the driver and poses a major hidden danger to driving safety, causing the driver to face higher risks when dealing with complex road conditions. Therefore, in order to address the above problems, a rearview mirror protective cover with an embedded dashcam and its assembly method are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a rearview mirror protective cover with an embedded dashcam and an assembly method thereof, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An interior rearview mirror protective cover for an embedded dashcam includes a windshield mounting base, on the front end of which an interior rearview mirror protective cover assembly is mounted. The rearview mirror protective cover assembly includes a protective housing, with an edge protection strip fixed to the outer edge of the protective housing. A protective camera integrated component is mounted on the front end of the protective housing. The protective camera integrated component includes a support base fixed to the top of the protective housing. A guide support tube is fixed to the center of the front end of the support base. An embedded dashcam camera is elastically connected to the front of the guide support tube. Inclined guide grooves are formed on both sides of the outer wall of the embedded dashcam camera. A lens protection mechanism is rotatably mounted on the outside of the embedded dashcam camera. The lens protection mechanism includes a positioning seat, with a sliding adjustment bead fixed to the center of the inner side of the positioning seat. An arc-shaped adapter slot is formed at the rear of the positioning seat, and a protective plate is fixed to the outer side of the positioning seat.

[0006] As a further optimization of the present invention, the protective housing includes a housing body, a protective component storage groove is provided on the top inner side of the housing body, a lens mounting cavity and a friction cleaning groove are provided in the middle of the housing body, a debris discharge outlet is provided at the bottom of the housing body, a positioning limit pin is inserted above the support base, and a pin hole adapted to the positioning limit pin is provided above the embedded dashcam camera.

[0007] As a further optimization of the present invention, the protective component storage groove corresponds to the friction cleaning groove, and the protective component storage groove is located above the friction cleaning groove.

[0008] As a further optimization of the present invention, the lens mounting cavity is located between two friction cleaning grooves, the friction cleaning grooves are located in front of the lens mounting cavity, and the inner side of the friction cleaning grooves has an arc-shaped structure.

[0009] As a further optimization of the present invention, the inner side of the inclined guide groove has an arc-shaped structure, the lateral projection of the inclined guide groove is a 45° inclined structure, and it slides in cooperation with the sliding adjustment bead.

[0010] As a further optimization of the present invention, the positioning seat axis is collinear with the embedded dashcam camera axis, the rear of the positioning seat is rotatably connected to the inner side of the support base, and the inner side of the arc-shaped adapter slot has an arc structure.

[0011] As a further optimization of the present invention, the protective plate has a plurality of observation slots arranged in a honeycomb pattern on its surface, with an interval of 2-3 mm between adjacent observation slots, and a hemispherical fitting ball is fixed on the back of the protective plate, and the fitting ball fits into the lens in the lens mounting cavity.

[0012] As a further optimization of the present invention, the inner rear side of the embedded dashcam camera has a cavity structure, the guide support tube slides with the inner rear side of the embedded dashcam camera, and a reset spring is installed between the two.

[0013] As a further optimization of the present invention, the positioning limiting pin is interference-fitted with the pin hole of the embedded dashcam camera, and the inner side of the pin hole has an arc-shaped structure.

[0014] A method for assembling a protective cover for an embedded dashcam rearview mirror: Step 1: Attach the windshield mounting bracket to the inner surface of the windshield using high-strength structural adhesive, ensuring the bonding surface is free of bubbles and impurities. Allow it to cure to ensure installation rigidity. Embed the rearview mirror lens into the lens mounting cavity of the protective housing and fix it using an interference fit. Adjust the lens angle to meet the field of vision standard. Apply sealant to the edges to prevent moisture intrusion. Assemble the protective camera integrated component. Slide the guide support tube into the cavity structure of the embedded dashcam camera. Install the built-in reset spring and test the elastic reset stroke. Pre-assemble the sliding adjustment ball with the tilt guide groove to ensure smooth sliding without jamming. Fix the protective camera integrated component to the front end of the protective housing. Adjust the position of the support base to align the lens protection mechanism with the lens mounting cavity coaxially. Finally, lock the protective cover assembly to the windshield mounting bracket using a snap-fit ​​structure to complete the overall assembly. Step 2: In the natural state, the preload of the reset spring pushes the embedded dashcam camera to extend outward along the guide support tube, causing the sliding adjustment ball to be at the low end of the inclined guide groove, so that the two lens protection mechanisms are symmetrically distributed in front of the lens. Step 3: When a completely clear rearview mirror view is required, press the embedded dashcam camera axially. The pressure will cause the embedded dashcam camera to move along the guide support tube to the support base. The sliding adjustment ball will slide upward along the inclined guide groove, causing the positioning seat to rotate upward around the support base. The corner area of ​​the positioning seat will generate frictional damping vibration with the arc-shaped inner wall of the friction cleaning groove, causing the dust and debris attached to the surface of the protective plate to fall off. The debris will be discharged by gravity through the debris discharge outlet. Step 4: When the lens protection mechanism is fully rotated into the protective component storage slot, the pin hole of the embedded dashcam camera is precisely aligned with the positioning limit pin. Inserting the positioning limit pin achieves an interference fit, locking the axial position of the camera and preventing the protection mechanism from rotating accidentally during driving. Step 5: When it is necessary to restore the protective state, pull out the positioning limit pin. The elastic force of the reset spring pushes the embedded dashcam camera to return to its axial position. The sliding adjustment ball slides down the inclined guide groove, causing the lens protection mechanism to automatically rotate back to the front of the lens.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the protective plate and observation slot solve the problem that the rearview mirror lens is directly exposed and easily cracked by collision, and the fragments fall off. The rigid protective plate blocks the impact of foreign objects, and the honeycomb slots with a 2-3mm interval ensure the visibility. Even if the lens is cracked, it can intercept fragments and avoid safety hazards. 2. In this invention, the switchable lens protection mechanism and friction cleaning groove solve the drawbacks of fixed or missing protective structures in the prior art. The protective and retracted states can be switched with one button by pressing the camera. The friction damping vibration during rotation can also automatically clean debris from the surface of the protective plate, thus balancing protection and visual clarity. 3. In this invention, the embedded dashcam camera and integrated protective structure solve the problem of separate installation of the rearview mirror and dashcam in the prior art, which occupies space. The camera function and the protective function are integrated into one, simplifying the installation process. At the same time, the switching action of the protective mechanism does not affect the camera's field of view, thus improving driving safety and ease of use. Attached Figure Description

[0018] Please see Figures 1-9 The present invention provides a technical solution: A rearview mirror protective cover for an embedded dashcam and its assembly method include a windshield mounting base 1, with a rearview mirror protective cover assembly 2 mounted on the front end of the windshield mounting base 1; the rearview mirror protective cover assembly 2 includes a protective housing 21, with an edge protection strip 22 fixed to the outer edge of the protective housing 21, and a protective camera integrated component 23 mounted on the front end face of the protective housing 21; the protective camera integrated component 23 includes a support base 231, which is fixed to the top of the protective housing 21, and a guide support tube is fixed to the center of the front end face of the support base 231. 232, an embedded dashcam camera 233 is elastically connected to the front of the guide support tube 232. The embedded dashcam camera 233 has inclined guide grooves 234 on both sides of its outer wall. A lens protection mechanism 235 is rotatably installed on the outside of the embedded dashcam camera 233. The lens protection mechanism 235 includes a positioning seat 2351. A sliding adjustment bead 2352 is fixed in the middle of the inner side of the positioning seat 2351. An arc-shaped adapter slot 2353 is opened at the rear of the positioning seat 2351. A protective plate 2354 is fixed on the outer side of the positioning seat 2351.

[0019] As a further implementation of this solution, the protective housing 21 includes a housing body 211, a protective component storage groove 212 is provided on the top inner side of the housing body 211, a lens mounting cavity 213 and a friction cleaning groove 214 are provided in the middle of the housing body 211, a debris discharge outlet 215 is provided at the bottom of the housing body 211, a positioning limit pin 236 is inserted above the support base 231, and a pin hole adapted to the positioning limit pin 236 is provided above the embedded dashcam camera 233. To further explain, the protective housing 21 has a protective component storage groove 212, a lens mounting cavity 213, a friction cleaning groove 214, and a debris discharge outlet 215 in the housing body 211, and is equipped with a positioning limit pin 236, which provides a storage path for the lens protection mechanism 235 and can lock the state. As a further implementation of this solution, the lens mounting cavity 213 is located between two friction cleaning grooves 214, the friction cleaning grooves 214 are located in front of the lens mounting cavity 213, and the inner side of the friction cleaning grooves 214 has an arc-shaped structure. To further explain, the protective component storage slot 212 and the friction cleaning slot 214 are designed to correspond vertically, so that the lens protection mechanism 235 can accurately align with the slot when it rotates. The friction and vibration help to shake off debris, ensuring smooth switching and clear vision, and adapting to the overall structural linkage requirements. As a further implementation of this solution, the lens mounting cavity 213 is located between two friction cleaning grooves 214. The friction cleaning grooves 214 are located in front of the lens mounting cavity 213, and the inner side of the friction cleaning grooves 214 has an arc-shaped structure. The arc-shaped friction cleaning grooves 214 are adapted to the rotation trajectory to enhance the chip removal effect. As a further implementation of this solution, the inner side of the inclined guide groove 234 has an arc-shaped structure, the lateral projection of the inclined guide groove 234 is a 45° inclined structure, and it slides in conjunction with the sliding adjustment bead 2352. As a further implementation of this solution, the axis of the positioning seat 2351 is collinear with the axis of the embedded dashcam camera 233. The rear of the positioning seat 2351 is rotatably connected to the inner side of the support base 231. The inner side of the arc-shaped adapter slot 2353 has an arc-shaped structure. Sufficient lubricating oil can be added to the inner side of the arc-shaped adapter slot 2353 to reduce the friction of the contact surface, avoid friction damage, and extend the service life of the components. As a further implementation of this solution, the protective plate 2354 has multiple observation slots 2355 arranged in a honeycomb pattern on its surface, with an interval of 2-3mm between adjacent observation slots 2355. A hemispherical bonding ball 2356 is fixed on the back of the protective plate 2354, and the bonding ball 2356 is bonded to the lens in the lens mounting cavity 213. To further explain, the observation slots 2355 (2-3mm intervals) of the protective plate 2354 ensure the field of vision and block foreign objects and fragments, while the hemispherical fitting ball bearings 2356 reduce frictional damage to the lens inside the lens mounting cavity 213. As a further implementation of this solution, the inner rear of the embedded dashcam camera 233 is a cavity structure. The guide support tube 232 slides with the inner rear of the embedded dashcam camera 233, and a reset spring is installed between the two. With the reset spring, one-button switching and automatic reset can be achieved without additional tools. As a further implementation of this solution, the positioning limit pin 236 is interference-fitted with the pin hole of the embedded dashcam camera 233, and the inner side of the pin hole has an arc-shaped structure. This setting can firmly lock the retracted state and prevent displacement caused by driving vibration.

[0020] Workflow: The windshield mounting bracket 1 is bonded to the inner surface of the windshield with high-strength structural adhesive, ensuring that the bonding surface is free of bubbles and impurities. It is then allowed to cure to ensure installation rigidity. The rearview mirror lens is embedded into the lens mounting cavity 213 of the protective housing 21 and fixed by interference fit. The lens angle is adjusted to meet the field of vision standard. Sealant is applied to the edges to prevent moisture intrusion. The protective camera integrated component 23 is assembled. The guide support tube 232 is slidably fitted with the cavity structure of the embedded dashcam camera 233. The built-in reset spring is installed and the elastic reset stroke is tested. The sliding adjustment ball 2352 is pre-assembled with the tilt guide groove 234 to ensure smooth sliding without jamming. The protective camera integrated component 23 is fixed to the front end of the protective housing 21. The position of the support base 231 is adjusted so that the lens protection mechanism 235 and the lens mounting cavity 213 are coaxially aligned. Finally, the protective cover assembly 2 and the windshield mounting bracket 1 are locked by a snap-fit ​​structure to complete the overall assembly. In its natural state, the preload of the return spring pushes the embedded dashcam camera 233 to extend outward along the guide support tube 232, causing the sliding adjustment bead 2352 to be at the low end of the inclined guide groove 234, so that the two lens protection mechanisms 235 are symmetrically distributed in front of the lens. When a completely clear rearview mirror view is required, the embedded dashcam camera 233 is pressed axially. The pressure causes the embedded dashcam camera 233 to move along the guide support tube 232 toward the support base 231. The sliding adjustment bead 2352 slides upward along the inclined guide groove 234, causing the positioning seat 2351 to rotate upward around the support base 231. The corner area of ​​the positioning seat 2351 and the arc-shaped inner wall of the friction cleaning groove 214 generate friction damping vibration, causing the dust and debris attached to the surface of the protective plate 2354 to fall off. The debris is discharged by gravity through the debris discharge port 215. When the lens protection mechanism 235 is fully rotated into the protective component storage slot 212, the pin hole of the embedded dashcam camera 233 is precisely aligned with the positioning limit pin 236. The positioning limit pin 236 is inserted to achieve an interference fit, locking the axial position of the camera and preventing the protection mechanism from rotating accidentally during driving. When the protective state needs to be restored, the positioning limit pin 236 is pulled out, and the elastic force of the reset spring pushes the embedded dashcam camera 233 to return to its axial position. The sliding adjustment bead 2352 slides down along the inclined guide groove 234, causing the lens protection mechanism 235 to automatically rotate back to the front of the lens.
