Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and in particular to an anti-detachment structure for an integrated exterior rearview mirror. Background Technology

[0002] In the automotive industry, integrated exterior rearview mirror assemblies are crucial components installed on vehicle doors, and their stability is vital for drivers to obtain a clear view of the outside world and ensure driving safety. However, current exterior rearview mirrors face significant stability challenges in practical use.

[0003] When a car travels on bumpy roads, the exterior rearview mirror assembly is subjected to resonance caused by the vehicle's overall vibration. In existing technology, the steering gear mounting screw is the only component that securely connects the lens to the mirror mount. Under prolonged vibration, this mounting screw is prone to slipping. Once the screw slips, the connection between the lens and the mount loosens, potentially causing the lens to detach. This not only prevents the driver from properly observing the outside environment, seriously affecting driving safety, but may also damage the exterior rearview mirror, increasing vehicle repair costs.

[0004] Currently, some solutions to the problem of exterior rearview mirror lenses easily detaching involve increasing the tightening torque of the fixing screws to improve connection stability. However, this method has limited effectiveness under long-term vibration environments, and excessive tightening torque may damage the threaded structure. Other solutions attempt to use adhesives for auxiliary fixing, but the durability and reliability of adhesives are difficult to guarantee in complex outdoor environments, and the use of adhesives also brings inconvenience to subsequent maintenance and replacement. Therefore, developing an anti-detachment structure that effectively prevents exterior rearview mirror lenses from detaching, is simple in structure, and easy to maintain is of significant practical importance. Utility Model Content

[0005] Purpose of the utility model: To provide an anti-detachment structure for an integrated exterior rearview mirror, so as to solve the above-mentioned problems existing in the prior art.

[0006] Technical solution: An anti-detachment structure for an integrated exterior rearview mirror, comprising: a lens, the lens being mounted on a base by multiple locking bolts, the sidewalls of the locking bolts being provided with annular grooves, the base being provided with a cover plate groove, the cover plate groove being provided with a plurality of limiting grooves arranged in a circumferential array, a limiting pin being slidably disposed in the limiting groove, a through hole being provided at the center of the cover plate groove, an anti-detachment limiting mechanism being installed at the through hole to drive one end of the limiting pin to move into the annular groove, and a cover plate being provided on the cover plate groove.

[0007] Furthermore, the anti-detachment limiting mechanism includes: a drive column, which is placed inside the through hole. Two hook plates are hinged to the end of the drive column. The two hook plates are clamped by a torsion spring. A drive ramp is provided on the hook plate. A separation cone plate is provided on the cover plate. The separation cone plate cooperates with the drive ramp to separate the hook plates. The hooks on the hook plates cooperate with the slots on the separation cone plate to prevent the drive column from detaching from the through hole.

[0008] Furthermore, the separating cone plate is mounted on the cover plate via a bracket.

[0009] Furthermore, the limiting pin is provided with a guide slope.

[0010] Furthermore, the cross-section of the annular groove is circular.

[0011] Furthermore, the cross-section of the annular groove is elliptical.

[0012] Furthermore, the cover plate and the bracket are connected by bolts or clips.

[0013] Furthermore, the cover plate and the bracket are fixed by welding or bonding.

[0014] Furthermore, the bracket is provided with a separation hole for inserting external components, which is used to separate the hooks of the two hook plates from the slots.

[0015] Furthermore, it also includes a drive plate, with two separation columns vertically arranged below the drive plate. The separation columns are placed in the separation holes, and the ends of the separation columns are provided with anti-detachment parts to prevent them from disengaging from the separation holes. A thrust spring is fitted on the separation columns. Beneficial effects

[0016] Enhanced connection stability and reduced risk of detachment: Traditional exterior rearview mirrors rely on a single fixing screw to connect the lens and the mount. On bumpy roads, the screw can easily slip back, causing the lens to detach. This anti-detachment structure features an annular groove on the side wall of the locking bolt, and multiple limiting grooves arranged circumferentially within the cover plate groove of the base. Limiting pins slide within these grooves, and the anti-detachment limiting mechanism controls the movement of these pins into the annular grooves. This design makes the connection between the lens and the mount more secure. The multiple limiting pins and the annular grooves effectively disperse vibration stress, greatly reducing the possibility of the lens detaching in bumpy conditions and ensuring driving safety.

[0017] The structure is ingeniously designed and easy to operate: the drive column of the anti-detachment limiting mechanism is hinged to two hook plates, which use torsion springs to provide clamping force. The separation cone plate on the cover plate cooperates with the drive ramp of the hook plate to separate the hook plates, and the hook and slot cooperate to prevent the drive column from detaching. During installation, the cover plate is installed in place, the separation cone plate pushes the hook plate to separate, and the limiting pin enters the annular groove under the action of the drive column to complete the anti-detachment locking. During disassembly, the hook and slot of the hook plate are separated by inserting the external component into the separation hole of the bracket, which releases the anti-detachment restriction. The operation is simple and facilitates later maintenance and replacement.

[0018] Highly adaptable and widely applicable: The cross-section of the annular groove is designed to be circular or elliptical, allowing selection based on different usage requirements and material properties, thus improving the adaptability of the anti-detachment structure. The cover plate and bracket can be connected in various ways, such as bolted, snap-fit, welded, or adhesive, meeting different production processes and cost requirements. This makes it widely applicable in the production of various automotive exterior rearview mirrors, enhancing their overall performance. Attached Figure Description

Detailed Implementation

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] like Figures 1-4As shown, an anti-detachment structure for an integrated exterior rearview mirror includes: a lens 1, which is mounted on a base 3 by multiple locking bolts 2. The sidewall of the locking bolts 2 is provided with an annular groove 21. The base 3 is provided with a cover plate groove 31. Multiple limiting grooves 32 are arranged in a circumferential array in the cover plate groove 31. Limiting pins 33 are slidably arranged in the limiting grooves 32. A through hole 34 is provided at the center of the cover plate groove 31. An anti-detachment limiting mechanism 35 that drives one end of the limiting pin 33 to move into the annular groove 21 is installed at the through hole 34. A cover plate 36 is provided on the cover plate groove 31. The anti-detachment limiting mechanism 35 includes: a drive column 351, which is placed inside the through hole 34. Two hook plates 352 are hinged to the end of the drive column 351. The two hook plates 352 are clamped by a torsion spring. A drive ramp 353 is provided on each hook plate 352. A separation cone plate 354 is provided on the cover plate 36. The separation cone plate 354 cooperates with the drive ramp 353 to separate the hook plates 352. A hook 355 on the hook plate 352 cooperates with a slot 356 on the separation cone plate 354 to prevent the drive column 351 from detaching from the through hole 34. The separation cone plate 354 is mounted on the cover plate 36 via a bracket 37. A guide ramp is provided on the limiting pin 33. The cross-section of the annular groove 21 is circular. The cross-section of the annular groove 21 is elliptical. The cover plate 36 and the bracket 37 are connected by bolts or snap fasteners. The cover plate 36 and the bracket 37 are fixed by welding or bonding. The bracket 37 is provided with a separation hole 38 for inserting external components, used to separate the hooks 355 of the two hook plates 352 from the slots 356. It also includes a drive plate 39, with two separation posts 310 vertically arranged below the drive plate 39. The separation posts 310 are placed in the separation hole 38, and the ends of the separation posts 310 are provided with anti-detachment parts 311 to prevent them from falling out of the separation hole 38. A thrust spring 312 is fitted on the separation post 310.

[0026] The base 3 serves as a support structure, bearing the lens 1 and other related components. The cover plate groove 31 on the base 3 provides space for the subsequent installation of the limiting pin 33, the anti-detachment limiting mechanism 35, and the cover plate 36. Multiple limiting grooves 32 arranged in a circumferential array within the cover plate groove 31 are used to install the limiting pin 33, allowing it to slide within them and thus limiting the locking bolt 2, preventing the lens 1 from falling off due to bolt loosening.

[0027] The limiting pin 33 is one of the key components of the anti-detachment structure. It slides within the limiting groove 32. When the anti-detachment limiting mechanism 35 drives one end of the pin to move into the annular groove 21, it prevents the locking bolt 2 from rotating or displacing, thereby effectively preventing the lens 1 from falling off the base 3. The guide slope provided on the limiting pin 33 helps it enter the annular groove 21 more smoothly, improving the convenience of installation and anti-detachment.

[0028] The anti-detachment limiting mechanism 35 is the core component controlling the movement of the limiting pin 33. It is installed in the through hole 34 at the center of the cover plate groove 31 of the base 3. The anti-detachment limiting mechanism 35 includes a drive column 351, which is placed in the through hole 34 to transmit power to drive the limiting pin 33. Two hook plates 352 are hinged to the ends of the drive column 351 and have a clamping force under the action of torsion springs, maintaining a certain position under normal conditions. The drive inclined surface 353 provided on the hook plate 352 cooperates with the separation cone plate 354 on the cover plate 36. The separation cone plate 354 pushes the drive inclined surface 353, causing the two hook plates 352 to separate. The latch 355 on the hook plate 352 cooperates with the latch 356 on the separation cone plate 354. After the limiting pin 33 enters the annular groove 21, it prevents the drive column 351 from disengaging from the through hole 34, ensuring the stable operation of the anti-detachment limiting mechanism 35, and thus ensuring the secure connection between the lens 1 and the base 3.

[0029] The separating cone plate 354 is mounted on the cover plate 36. Through its engagement with the driving ramp 353 of the hook plate 352, it enables the hook plate 352 to separate, playing a crucial driving role in the entire installation process of the anti-detachment structure. The separating cone plate 354 is mounted on the cover plate 36 via a bracket 37. The bracket 37 supports and positions the separating cone plate 354, ensuring its accurate relative position to other components and enabling it to function properly.

[0030] The cover plate 36 is used to close the cover plate groove 31, protecting internal components such as the limiting pin 33 and the anti-detachment limiting mechanism 35, while also providing an installation position for the separation cone plate 354. The cover plate 36 can be connected to the bracket 37 in various ways, such as bolted connection, snap-fit ​​connection, welding fixation, or adhesive fixation. Different connection methods can be selected according to actual production needs to meet different process and cost requirements.

[0031] The separation hole 38 provided on the bracket 37 is used to insert the outer component to separate the hooks 355 of the two hook plates 352 from the slots 356 when the exterior rearview mirror needs to be removed, so as to release the locking state of the anti-detachment limiting mechanism 35 and facilitate the maintenance and replacement of the exterior rearview mirror.

[0032] Two vertically arranged separation posts 310 below the drive plate 39 are positioned within the separation hole 38. When the drive plate 39 is operated, the separation posts 310 can push the hook plate 352, separating the hook 355 from the slot 356. An anti-detachment part 311 at the end of the separation post 310 prevents it from disengaging from the separation hole 38, ensuring stable operation. A thrust spring 312 mounted on the separation post 310 maintains its position when no external force is applied and helps it reset after the separation action is completed for future use. These components work together to form a complete and efficient integrated anti-detachment structure for the exterior rearview mirror, effectively solving the problem of the lens easily detaching when driving on bumpy roads, thus improving the safety and reliability of the exterior rearview mirror.

[0033] Work process

[0034] Installation Process: First, the lens 1 is initially installed on the base 3 using multiple locking bolts 2. Next, the limiting pins 33 are inserted into the limiting grooves 32 arranged in a circular array within the cover plate groove 31 of the base 3. At this time, the drive column 351 of the anti-detachment limiting mechanism 35 is placed in the through hole 34 at the center of the cover plate groove 31, and the two hook plates 352 hinged at its ends are held in a clamped state under the action of the torsion spring. During the insertion of the drive column 351, the separating cone plate 354 gradually approaches the hook plate 352. When the separating cone plate 354 contacts the driving inclined surface 353 on the hook plate 352, the separating cone plate 354 pushes the driving inclined surface 353, causing the two hook plates 352 to overcome the clamping force of the torsion spring and separate. The hooks 355 on the hook plate 352 cooperate with the slots 356 on the separating cone plate 354 to prevent the drive column 351 from disengaging from the through hole 34, completing the installation of the entire anti-detachment structure. At this time, the connection between the lens 1 and the base 3 is effectively reinforced, which can resist the vibration generated during vehicle operation.

[0035] Usage: During vehicle operation, especially on bumpy roads, the exterior rearview mirror assembly is subject to resonance caused by the vehicle's vibrations. At this time, because the limiting pin 33 is engaged in the annular groove 21 of the locking bolt 2, the rotation and displacement of the locking bolt 2 are restricted. Even under vibration, this prevents the lens 1 from falling off the base 3, ensuring the normal use of the exterior rearview mirror and meeting the driver's visibility requirements.

[0036] Disassembly process: When the exterior rearview mirror needs repair or replacement, the drive plate 39 is operated using external tools. Two vertically positioned separation posts 310 below the drive plate 39 are placed within separation holes 38 on the bracket 37. Anti-detachment parts 311 at the ends of the separation posts 310 prevent them from disengaging from the separation holes 38. A thrust spring 312 mounted on the separation post 310 provides assistance during operation. Pushing the drive plate 39 causes the separation posts 310 to push the hook plate 352, causing the hook 355 of the hook plate 352 to separate from the slot 356 on the separation cone plate 354. The drive post 351 is no longer restricted, and the limiting pin 33 disengages from the annular groove 21, thereby releasing the anti-detachment connection between the lens 1 and the base 3, facilitating subsequent disassembly.
