Description

Technical Field

[0001] This utility model relates to the field of automotive rearview mirror technology, and in particular to a folding mechanism for an electronic exterior rearview mirror. Background Technology

[0002] Accidents are inevitable during driving, and rearview mirrors, being the widest components mounted on a vehicle, are easily damaged by impacts and scratches when distance is insufficient. To minimize the risk of scratches, rearview mirrors need a folding function. Folding rearview mirrors can be retracted when navigating narrow roads, improving maneuverability. When the driver leaves the vehicle, the mirrors can also be folded up, protecting the mirror surface and reducing parking space requirements, effectively preventing scratches.

[0003] The existing rearview mirror folding mechanism does not completely fit the rearview mirror with the vehicle body after folding; there is still some gap. If a collision still occurs under these conditions, it will cause damage to the rearview mirror.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] This invention provides a folding mechanism for an electronic exterior rearview mirror, thereby effectively solving the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a folding mechanism for an electronic exterior rearview mirror, comprising:

[0007] A rotating seat, which is mounted on the vehicle body;

[0008] A rotating shaft, which is partially disposed on the rotating base, is vertically arranged;

[0009] A rotating arm, which is mounted on the rearview mirror and sleeved on the rotating shaft;

[0010] The rotating base and the rotating arm are provided with a plurality of limiting structures at their respective ends. When the plurality of limiting structures are in contact with each other, they restrict the rotation of the rotating base and the rotating arm. An elastic element is provided on the rotating arm, and the elastic element presses the rotating arm against the rotating base so that the limiting structures are in contact with each other.

[0011] Furthermore, the limiting structure includes a plurality of protruding limiting blocks, and the limiting blocks on the rotating seat and the rotating arm are misaligned with each other.

[0012] Furthermore, the limiting block is provided with a sloping structure at both ends in the rotation direction.

[0013] Furthermore, the number of limiting blocks on the rotating seat and the rotating arm are three each, and the three limiting blocks are arranged at equal angles.

[0014] Furthermore, the rotating shaft is provided with a plurality of locking blocks, and the rotating seat is provided with corresponding locking slots. When the rotating shaft is inserted into the rotating seat, the locking blocks and the locking slots cooperate with each other to restrict the rotation of the rotating shaft relative to the rotating seat.

[0015] Furthermore, the number of card slots is an integer multiple of the number of card blocks.

[0016] Furthermore, the card slot is provided with a release groove corresponding to one of the rotation angles of the card block. When the rotating shaft rotates to the corresponding rotation angle, the card block disengages from the release groove.

[0017] Furthermore, a stop is provided at the top of the rotating shaft, and a stepped surface is provided on the rotating arm. The stepped surface is located between the stop and the rotating seat, thereby restricting the separation of the rotating shaft from the rotating arm.

[0018] The beneficial effects of this utility model are as follows: By setting a limiting structure between the rotating seat and the rotating arm, and setting an elastic element on the rotating arm, the limiting structure can precisely fit and restrict the free rotation of the rotating arm after the rearview mirror is folded to a set angle. At the same time, the elastic element maintains the fitted state, thereby achieving a tight fit between the rearview mirror and the vehicle body in the folded state. If the rearview mirror is still subjected to external force at this time, the external force pushes the rearview mirror, causing the elastic element to deform and thus disengaging the limiting structure. The rearview mirror will continue to fold to a certain angle. After the external force disappears, the elastic element continues to keep the limiting structure fitted, thereby restricting rotation. This structure effectively solves the problems of existing rearview mirrors still having gaps after folding and being easily scratched, improving the vehicle's ability to pass through narrow spaces and parking safety. The overall structure is simple and compact, easy to install, and has good practicality and promotional value. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] like Figures 1 to 7 As shown: A folding mechanism for an electronic exterior rearview mirror, comprising:

[0029] Rotary seat 1, which is mounted on the vehicle body;

[0030] Rotating shaft 2 is partially mounted on rotating seat 1 and is vertically positioned.

[0031] Rotating arm 3 is mounted on the rearview mirror and sleeved on the rotating shaft 2;

[0032] Among them, a number of limiting structures 4 are provided at the ends of the rotating seat 1 and the rotating arm 3 that are close to each other. When the number of limiting structures 4 are in contact with each other, they restrict the rotation of the rotating seat 1 and the rotating arm 3. An elastic element is provided on the rotating arm 3. The elastic element presses the rotating arm 3 against the rotating seat 1 so that the limiting structures 4 are in contact with each other.

[0033] By setting a limiting structure 4 between the rotating base 1 and the rotating arm 3, and setting an elastic element on the rotating arm 3, the limiting structure 4 can precisely fit and restrict the free rotation of the rotating arm 3 after the rearview mirror is folded to a set angle. At the same time, the elastic element maintains the fitted state, thus achieving a tight fit between the rearview mirror and the vehicle body when folded. If the rearview mirror is still subjected to external force at this time, the external force pushes the rearview mirror, causing the elastic element to deform and thus disengaging the limiting structure 4. The rearview mirror will continue to fold to a certain angle. After the external force disappears, the elastic element continues to keep the limiting structure 4 fitted, thus restricting rotation. This structure effectively solves the problems of gaps and easy scraping of existing rearview mirrors after folding, improving the vehicle's ability to pass through narrow spaces and parking safety. The overall structure is simple and compact, easy to install, and has good practicality and promotional value.

[0034] In this embodiment, the limiting structure 4 includes a plurality of protruding limiting blocks 41, and the limiting blocks 41 on the rotating seat 1 and the rotating arm 3 are misaligned with each other.

[0035] The limiting structure 4 includes several protruding limiting blocks 41, which are respectively located on the relatively close sides of the rotating base 1 and the rotating arm 3, and are arranged in a staggered manner. When the rotating arm 3 rotates around the rotating axis 2 to the folded position, the limiting blocks 41 on the rotating base 1 and the rotating arm 3 will form a stable limiting fit through mutual interlocking, and will be further pressed together under the action of the elastic element to achieve a more stable fit. This structural design not only improves the positioning accuracy after folding, but also effectively prevents the rearview mirror from loosening or rebounding due to vibration or impact during driving, thus enhancing the safety and durability of use.

[0036] As a preferred embodiment of the above, the limiting block 41 is provided with a slope structure 42 at both ends in the rotation direction.

[0037] The limiting block 41 has a sloping structure 42 at each end in its rotation direction. This sloping structure 42 guides the limiting block 41 to gradually slide into the mating position as the rotating arm 3 rotates to the folding position, achieving a smooth transition and avoiding jamming or impact. Simultaneously, under the action of the elastic element, the limiting block 41 naturally transitions to a fully fitted state through the sloping structure 42, enhancing the self-positioning capability and cushioning effect of the limiting fit. This structure not only improves the smoothness of the folding process but also reduces wear between components, improving the overall durability and reliability of the structure.

[0038] When the rearview mirror is further squeezed by external force after being folded, the slope structure 42 cooperates to apply pressure to the elastic element, so that the rearview mirror can rotate a certain angle. If it fails to rotate to the position where the next limit block 41 cooperates, the external force disappears, and the elastic element rebounds, which will return the rearview mirror to the original folded position.

[0039] The number of limiting blocks 41 on the rotating seat 1 and the rotating arm 3 are 3 each, and the 3 limiting blocks 41 are arranged at equal angles.

[0040] Three limiting blocks 41 are arranged around the rotation axis 2 at equal angular intervals. The multiple limiting blocks 41 arranged at equal angles enable multi-point contact limiting when folded into place, effectively dispersing stress and improving structural stability. This design not only enhances the symmetry and stability of the limiting fit but also avoids wear or structural displacement caused by single-point force, further improving the durability and safety of the folding mechanism in long-term use.

[0041] In this embodiment, a plurality of locking blocks 21 are provided on the rotating shaft 2, and a corresponding locking groove 11 is provided on the rotating seat 1. When the rotating shaft 2 is inserted into the rotating seat 1, the locking blocks 21 and the locking groove 11 cooperate with each other to restrict the rotation of the rotating shaft 2 relative to the rotating seat 1.

[0042] The rotating shaft 2 is equipped with several locking blocks 21, and the rotating base 1 is equipped with corresponding locking slots 11 that match the locking blocks 21. When the rotating shaft 2 is inserted into the rotating base 1, the locking blocks 21 and the locking slots 11 engage with each other, thereby restricting the rotation of the rotating shaft 2 relative to the rotating base 1. This structure, through precise locking and positioning, prevents the rotating shaft 2 from loosening or deflecting during use, further improving the structural stability and reliability of the entire folding mechanism. This helps ensure the accuracy and repeatability of the rearview mirror folding movement and extends the service life of the device.

[0043] As a preferred embodiment of the above, the number of card slots 11 is an integer multiple of the number of card blocks 21.

[0044] Among them, a set of release grooves 12 are provided in the slot 11 corresponding to one of the rotation angles of the card block 21. When the rotating shaft 2 rotates to the corresponding rotation angle, the card block 21 is released from the release groove 12.

[0045] The number of slots 11 is an integer multiple of the number of blocks 21, so that after the rotating shaft 2 is inserted into the rotating seat 1, multiple blocks 21 can precisely engage at different angular positions, improving assembly flexibility and positioning stability. A set of slots 11 corresponding to the rotational angle of the blocks 21 is provided with a release groove 12. When the rotating shaft 2 rotates to a specific angle, the blocks 21 align with the release groove 12 and disengage, allowing the rotating shaft 2 to unlock and rotate within that angle range. This structure, through a set release angle, achieves conditional release and limit control of the rotating shaft 2, ensuring the rearview mirror's fixation at specific angles while also allowing smooth rotation during folding or unfolding, improving ease of use and safety.

[0046] As a preferred embodiment of the above, the top of the rotating shaft 2 is provided with a retaining edge 22, and the rotating arm 3 is provided with a stepped surface 31. The stepped surface 31 is located between the retaining edge 22 and the rotating seat 1, thereby restricting the separation of the rotating shaft 2 and the rotating arm 3.

[0047] A retaining edge 22 is provided at the top of the rotating shaft 2, and a stepped surface 31 is provided on the rotating arm 3. The stepped surface 31 is located between the retaining edge 22 and the rotating seat 1. Through this structure, after the rotating shaft 2 is inserted into the rotating seat 1 and assembled with the rotating arm 3, an axial limiting fit is formed between the retaining edge 22 and the stepped surface 31, thereby effectively preventing the rotating shaft 2 from disengaging from the rotating arm 3. This design achieves reliable positioning and structural integrity between components without adding additional fasteners, simplifies the assembly process, and improves the stability and safety of the entire folding mechanism.
