[0002] As a common mode of transportation, electric vehicles rely heavily on their rearview mirrors for safety. These mirrors help drivers observe traffic conditions behind the vehicle. In practice, the rearview mirrors need to be adjusted according to factors such as the driver's height, posture, and driving environment to ensure the driver has the best field of vision.

[0003] However, most existing electric vehicle rearview mirrors are fixed using threaded connections. This method requires repeated twisting of the support rod during installation, and long-term twisting or excessive twisting can easily cause stripping and damage to the threads. In addition, when adjusting the rearview mirror angle, it is often necessary to loosen the threads first, adjust to the appropriate angle, and then tighten them again. This often results in the rearview mirror angle still being incorrect after twisting and fixing, requiring multiple adjustments and causing poor usability. Utility Model Content

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0026] Example 1

[0027] Reference Figure 1-4 This is the first embodiment of the present utility model, which provides an auxiliary limiting device for a rearview mirror of an electric vehicle, including a mounting hoop 1, a support rod 2 and a rearview mirror 3. The support rod 2 is disposed on the upper end of the mounting hoop 1, and the rearview mirror 3 is disposed on the upper end of the support rod 2 and is movably connected to the support rod 2. A limiting fixing device 4 is provided on the upper end of the mounting hoop 1, and the support rod 2 is movably connected to the mounting hoop 1 through the limiting fixing device 4. A multi-position docking part 9 is provided on the lower end of the support rod 2.

[0028] The limiting and fixing device 4 includes an annular box 5, positioning components 6, and a control mechanism 7. The annular box 5 is fixedly connected to the upper end of the mounting hoop 1. There are two positioning components 6, which are respectively set on the left and right sides inside the annular box 5. The control mechanism 7 is set at the lower end of the two positioning components 6.

[0029] Specifically, the limiting and fixing device 4 enables the support rod 2 to be limited at multiple angles and easily adjusted. At the same time, it improves the ease of installation and limiting of the electric vehicle rearview mirror 3, eliminating the need for repeated twisting of the support rod 2 for disassembly and fixing in traditional threaded connections. Long-term twisting or excessive twisting can easily cause stripping and damage. In addition, sometimes the angle of the rearview mirror 3 is not correct when twisted and fixed, making adjustment troublesome.

[0030] Furthermore, during installation, the multi-position connector 9 at the lower end of the support rod 2 is inserted into the inner ring of the annular box 5. The fixing cylinder 91 presses the elastic rubber pad 8 to initially stabilize it, while pushing the clamp head 62 to compress the push spring 63. When the clamp slot 92 is aligned with the clamp head 62, the push spring 63 pushes the clamp head 62 into the clamp slot 92 to achieve the limit. During adjustment or disassembly, the rotating drive component 72 drives the drive disk 711 to rotate. Its arc-shaped extrusion groove 712 pushes the pressure rod 64 to make the clamp head 62 disengage from the clamp slot 92, and the support rod 2 can move freely. After release, the push spring 63 resets the clamp head 62 to reposition. All components achieve the limit and adjustment of the support rod 2 through mechanical linkage.

[0031] Example 2

[0032] The second embodiment of this utility model provides an auxiliary limiting device for a rearview mirror of an electric vehicle. The positioning component 6 includes a positioning rod 61, a locking head 62, a push spring 63, and a pressure rod 64. There are two positioning rods 61, which are respectively set at the front and rear ends of the right side inside the annular box 5. The left and right ends of the two positioning rods 61 are respectively fixedly connected to the left and right inner walls of the right side inside the annular box 5. The locking head 62 is sleeved on the left end surface of the two positioning rods 61 and is slidably connected to the two positioning rods 61. The left end of the locking head 62 extends into the inner ring of the annular box 5 and is movably connected to the annular box 5. There are two push springs 63, which are respectively sleeved on the surface of the two positioning rods 61, and the left and right ends are respectively fixedly connected to the right side of the locking head 62 and the right inner surface of the annular box 5. The pressure rod 64 is fixedly connected to the lower end of the locking head 62.

[0033] An elastic rubber pad 8 is provided on the inner ring of the annular box 5, and the elastic rubber pad 8 is fixedly connected to the annular box 5.

[0034] The multi-position docking component 9 includes a fixed cylinder 91 and a slot 92. The fixed cylinder 91 is sleeved on the lower end surface of the support rod 2 and is fixedly connected to the support rod 2. The fixed cylinder 91 corresponds to and is adapted to the annular box 5. There are several slots 92, which are evenly opened on the circumference of the fixed cylinder 91. The slots 92 correspond to and are adapted to the two locking heads 62 on both sides that extend into the inner circle of the annular box 5.

[0035] Specifically, by setting up positioning component 6 and multi-position docking component 9, the support rod 2 and the annular box 5 can be quickly snapped together and positioned. The corresponding slot 92 can be selected to complete the limit according to different angle requirements, which improves the installation efficiency and the convenience of angle adjustment.

[0036] Furthermore, during installation, the lower end of the support rod 2, along with the fixing cylinder 91, is inserted into the inner ring of the annular box 5. During insertion, the fixing cylinder 91 at the lower end of the support rod 2 will first contact the elastic rubber pad 8 of the inner ring of the annular box 5, which will play a role in compression and stabilization. The elastic buffer of the elastic rubber pad can reduce the rigid collision of subsequent vibrations. As the fixing cylinder 91 goes deeper into the annular box 5, it will squeeze the end of the two clips 62 that extends into the inner ring, causing the two clips 62 to slide to the left and right sides on the surface of the positioning rod 61. At the same time, the elastic force of the anti-push spring 63 will compress them. After the fixing cylinder 91 is fully inserted to the bottom, the slots 92 on the periphery of the fixing cylinder 91 will be aligned with the clips 62 in the positioning assembly 6. At this time, the clips 62 will automatically snap into the corresponding slots 92 under the push of the elastic force of the push spring 63, thereby quickly completing the fixed limit.

[0037] Example 3

[0038] The third embodiment of this utility model provides an auxiliary limiting device for electric vehicle rearview mirrors. The control mechanism 7 includes a linkage 71 and a driving component 72. The linkage 71 is disposed at the lower end of the two pressure rods 64, and the driving component 72 is sleeved on the surface of the annular box 5.

[0039] The linkage 71 includes a drive disk 711 and an arc-shaped extrusion groove 712. The drive disk 711 is sleeved on the inner wall of the annular box 5 and is rotatably connected to the annular box 5. There are two arc-shaped extrusion grooves 712, which are opened on the left and right sides of the drive disk 711 and correspond to the positions of the two pressure rods 64. The lower ends of the two pressure rods 64 are set inside the two arc-shaped extrusion grooves 712 and are movably connected to the arc-shaped extrusion grooves 712.

[0040] The driving component 72 includes a connecting rod 721 and a torsion ring 722. There are two connecting rods 721, which are fixedly connected to the lower surface of the driving disk 711 on opposite sides. The opposite ends of the two connecting rods 721 extend out of the annular box 5 and are movably connected to the annular box 5. The torsion ring 722 is sleeved on the surface of the annular box 5 and is rotatably connected to the annular box 5, and is fixedly connected to the ends of the two connecting rods 721 that extend out of the annular box 5.

[0041] Specifically, by cooperating with the linkage 71 and drive 72 of the control mechanism 7, convenient control of the limit state of the clamp head 62 is achieved. The angle adjustment or disassembly of the support rod 2 can be quickly completed by simply rotating the torsion ring 722, which improves the ease of operation and practicality of the device.

[0042] Furthermore, during subsequent angle adjustment or disassembly, the torsion ring 722 of the drive component 72 is rotated. The torsion ring 722 drives the drive disk 711 to rotate synchronously through the connecting rod 721. The arc-shaped extrusion grooves 712 on both sides of the drive disk 711 rotate accordingly. When the inclined surface of the arc-shaped extrusion groove 712 contacts the pressure rod 64, it pushes the pressure rod 64 to move to the left and right sides. The pressure rod 64 drives the clamp head 62 to slide against the elastic force of the push spring 63 to both sides of the annular box 5, so that the clamp head 62 disengages from the slot 92. At this time, the support rod 2 loses its limit and can rotate freely to adjust the angle or be pulled out directly upwards to complete the disassembly. After adjusting to the appropriate angle, the torsion ring 722 is released, and the elastic force of the push spring 63 pushes the clamp head 62 to reset. The clamp head 62 re-clamps into the corresponding slot 92, thereby fixing the angle of the support rod 2. If it is a disassembly operation, it is only necessary to keep the clamp head 62 out of the slot 92 to remove the fixing cylinder 91 at the lower end of the support rod 2 from the inner ring of the annular box 5.

[0043] Working principle:

[0044] The mounting clamp 1 is used to fit onto the vehicle frame to fix the entire device and the rearview mirror. During installation, the lower end of the support rod 2, together with the fixing cylinder 91, is inserted into the inner ring of the annular box 5. During the insertion process, the fixing cylinder 91 at the lower end of the support rod 2 will first contact the elastic rubber pad 8 of the inner ring of the annular box 5, which plays a role in squeezing and stabilizing. The elastic buffer of the elastic rubber pad can reduce the rigid impact of subsequent vibration. As the fixing cylinder 91 goes deeper into the annular box 5, it squeezes the end of the two clips 62 that extends into the inner ring, causing the two clips 62 to slide to the left and right sides on the surface of the positioning rod 61. At the same time, the elastic force of the anti-push spring 63 squeezes and compresses them. After the fixing cylinder 91 is fully inserted to the bottom, the slots 92 on the periphery of the fixing cylinder 91 will be aligned with the clips 62 in the positioning component 6. At this time, the clips 62 will automatically snap into the corresponding slots 92 under the push of the elastic force of the push spring 63, thereby quickly completing the fixed limit.

[0045] When adjusting the angle or disassembling, rotate the torsion ring 722 of the drive component 72. The torsion ring 722 drives the drive disk 711 to rotate synchronously through the connecting rod 721. The arc-shaped extrusion grooves 712 on the left and right sides of the drive disk 711 rotate accordingly. When the arc surface of the arc-shaped extrusion groove 712 contacts the pressure rod 64, it will push the pressure rod 64 to move to the left and right sides. The pressure rod 64 drives the clamp head 62 to slide against the elastic force of the push spring 63 to both sides of the annular box 5, so that the clamp head 62 disengages from the slot 92. At this time, the support rod 2 loses its limit and can rotate freely to adjust the angle or be pulled out directly upwards to complete the disassembly. After adjusting to the appropriate angle, release the torsion ring 722. The elastic force of the push spring 63 pushes the clamp head 62 to reset. The clamp head 62 re-clamps into the corresponding slot 92 to fix the angle of the support rod 2. If it is a disassembly operation, just keep the clamp head 62 out of the slot 92 and the fixing cylinder 91 at the lower end of the support rod 2 can be taken out from the inner ring of the annular box 5.

[0046] In summary, by using the mounting clamp 1, support rod 2, rearview mirror 3, limiting and fixing device 4, annular box 5, positioning component 6, positioning rod 61, clamp head 62, push spring 63, pressure rod 64, control mechanism 7, linkage component 71, drive disc 711, arc-shaped extrusion groove 712, drive component 72, connecting rod 721, torsion ring 722, elastic rubber pad 8, multi-position docking component 9, fixing cylinder 91, and clamp groove 92 in combination, the effects of rapid limiting and fixing and angle adjustment are achieved, and the operation is convenient.
