Technical Field

[0001] This utility model relates to the field of automotive rearview mirror technology, specifically to a folding structure for automotive rearview mirrors. Background Technology

[0002] Rearview mirrors are tools used by drivers to directly obtain external information about the rear, sides, and bottom of the vehicle while seated in the driver's seat. To facilitate driver operation, prevent traffic accidents, and ensure personal safety, all countries mandate the installation of rearview mirrors on vehicles, and all rearview mirrors must be adjustable. Rearview mirrors reflect the situation behind, to the sides, and below the vehicle, allowing the driver to indirectly see these areas; they act as a "second eye," expanding the driver's field of vision.

[0003] Rearview mirrors are essential for cars while driving. However, existing car rearview mirrors have a limited rotation angle and are prone to breakage in the event of a collision, with the mirrors sometimes losing their handles. This significantly affects their continued usability. Summary of the Invention

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a folding structure for automotive rearview mirrors, which solves the problems mentioned in the background art, such as the small rotation angle of existing automotive exterior rearview mirrors during use, and the easy breakage of the mirrors and the broken ears of the container in the event of a collision, which greatly affects the subsequent use of automotive rearview mirrors.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0009] The PCB board is inserted horizontally into the base component, and a fixing mechanism is provided on the outside of the base component to limit the position of the base component;

[0010] The first and second retaining rings are set at the top and bottom ends of the PCB board and are located inside the base component.

[0011] A connecting mechanism is located inside the knob and is used to limit the position of the knob.

[0012] Furthermore, the fixing mechanism includes a connecting plate, a first connector, and a second connector. The connecting plate is symmetrically fixed on the left and right sides of the base component, the first connector is fixed on one side of the base component, and the second connector is symmetrically fixed on the other end of the base component. The first connector and the second connector are engaged with the inner wall of the rearview mirror.

[0013] Furthermore, the base component has symmetrically provided limiting grooves on its left and right sides, and the knob component is slidably embedded in the limiting grooves.

[0014] Furthermore, the connecting mechanism includes a connecting groove, a connecting plate, and an extension rod. The connecting groove is located at the center of the first retaining ring and the second retaining ring and extends through the interior of the PCB board. The connecting plate is fixed to the lower end face of the knob and engages with the limiting groove. The extension rod is fixed to the lower end face of the knob and extends into the connecting groove.

[0015] Furthermore, a sealing ring is fitted onto the outer surface of the extension rod.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] like Figure 1 As shown, an embodiment of the present invention provides a folding structure for a car rearview mirror, including a base 1 and knobs 10 disposed on the left and right sides of the base 1, and further including:

[0030] The base component 1 serves as the basic support component of the entire folding structure. The groove 5 is designed to cooperate with the knob component 10. The fixing mechanism ensures its installation stability within the rearview mirror. The PCB board 6 can precisely control the rotation angle of the knob component 10, thereby improving the device's performance.

[0031] like Figure 2 and 3 As shown, the fixing mechanism includes a connecting plate 2, a first connector 3, and a second connector 4. The connecting plate 2 is symmetrically fixed on the left and right sides of the base component 1, the first connector 3 is fixed on one side of the base component 1, and the second connector 4 is symmetrically fixed on the other end of the base component 1. The first connector 3 and the second connector 4 are engaged with the inner wall of the rearview mirror. The first connector 3 and the second connector 4 can limit the position of the base component 1, preventing the base component 1 from shifting or shaking, thus ensuring the stability of its subsequent processing. The connecting plate 2 can further limit the base component 1. The engagement of the first connector 3 and the second connector 4 with the inner wall of the rearview mirror limits the position of the base component 1, preventing it from shifting or shaking. The connecting plate 2 further enhances the installation stability of the base component 1.

[0032] like Figure 3As shown, the base 1 has symmetrically provided limiting grooves 5 on its left and right sides, and the knob 10 slides into the limiting grooves 5. The limiting grooves 5 can limit the connecting plate 11 at the lower end of the knob 10. The limiting of the connecting plate 11 at the lower end of the knob 10, together with the first retaining ring 7 and the second retaining ring 8, ensures the stability of the knob 10.

[0033] like Figure 4 As shown, the PCB board 6 is inserted horizontally into the base component 1. A fixing mechanism is provided on the outside of the base component 1 to limit the position of the base component 1. The PCB board 6 precisely and intelligently controls the rotation angle of the knob component 10 to achieve precise adjustment of the rearview mirror folding angle.

[0034] like Figure 5 As shown, retaining ring 7 and retaining ring 8 are set at the upper and lower ends of PCB board 6 and located inside base 1; they are elastic and can reset when the rearview mirror is hit, avoiding the breakage of the ear; they cooperate with connecting groove 9 and extension rod 12 to limit the position of knob 10 and ensure its stability when rotating.

[0035] like Figure 2 As shown, the connecting mechanism is located inside the knob 10 and is used to limit the position of the knob 10;

[0036] The upper end of the knob 10 is connected to the rearview mirror, and the angle of the rearview mirror is adjusted by rotating it; the lower end cooperates with the connecting mechanism and slides within the limiting groove 5 to realize the rotation function; the steering groove 14 can be connected to the rearview mirror or the motor, which facilitates manual or electric adjustment of the rearview mirror position.

[0037] like Figure 3 and 4 As shown, the connecting mechanism includes a connecting groove 9, a connecting plate 11, and an extension rod 12. The connecting groove 9 is located at the center of the first retaining ring 7 and the second retaining ring 8 and extends through the interior of the PCB board 6. The connecting plate 11 is fixed to the lower end face of the knob 10 and engages with the limiting groove 5. The extension rod 12 is fixed to the lower end face of the knob 10 and extends into the connecting groove 9. The connecting groove 9 allows the extension rod 12 to connect with the knob. The PCB board 6 can precisely and intelligently control the rotation angle of the knob 10. The control system enhances the intelligence of the device. The connecting plate 11 limits the knob 10, preventing it from wobbling. The retaining ring 7 and retaining ring 8 work together to ensure the stability of the knob 10. Since the upper end of the knob 10 can be connected to the rearview mirror, the rearview mirror can be rotated and adjusted, increasing the rotation angle. Because retaining ring 7 and retaining ring 8 are elastic, they can reset the rearview mirror when it collides, preventing the mirror from breaking.

[0038] The connecting groove 9 connects to the extension rod 12 to achieve mechanical linkage between the knob 10 and the PCB board 6, the first retaining ring 7, and the second retaining ring 8.

[0039] The connecting plate 11 engages with the limiting groove 5, further limiting the position of the knob 10 and preventing it from shaking.

[0040] The extension rod 12 is inserted into the connecting groove 9 to transmit the rotation action of the knob 10; the sealing ring 13 seals the connection to prevent dust from entering and affecting the detection accuracy of the PCB board 6;

[0041] like Figure 6 As shown, a sealing ring 13 is fitted on the outer surface of the extension rod 12. The sealing ring 13 can seal the connection between the first retaining ring 7, the second retaining ring 8, and the PCB board 6, preventing dust and other contaminants from entering the connection and affecting the accuracy of the PCB board 6 detection.

[0042] like Figure 6 As shown, a steering groove 14 is provided at the center of the outer surface of the knob 10, which can be connected to the rearview mirror.

[0043] This allows the rearview mirror to be rotated and adjusted, increasing the rotation angle. The lower end of another set of knobs 10 can be connected to a motor, which can then drive the knobs 10 for adjustment, thereby intelligently adjusting and controlling the position of the rearview mirror.

[0044] Working principle: First, it should be noted that the position of the base component 1 can be limited by the connection component 3 and the connection component 4, which can prevent the base component 1 from shifting or shaking, thereby ensuring the stability of its subsequent processing. The connection plate 2 can further limit the base component 1. The left and right sides of the base component 1 are symmetrically provided with limiting grooves 5, and the knob component 10 slides into the limiting grooves 5.

[0045] Secondly, the connecting groove 9 can be connected to the extension rod 12, and the PCB board 6 can precisely and intelligently control the rotation angle of the knob 10, thereby improving the intelligence of the device. Since the upper end of the knob 10 can be connected to the rearview mirror, the rearview mirror can be rotated and adjusted, thus increasing the rotation angle. Since the retaining ring 7 and retaining ring 8 are elastic, they can reset the rearview mirror when it collides, thus preventing the ear from breaking. Since the steering groove 14 can be connected to the rearview mirror, the rearview mirror can be rotated and adjusted, thus increasing the rotation angle. The lower end of the other set of knobs 10 can be connected to the motor, and then the knobs 10 can be driven and adjusted, thus intelligently adjusting and controlling the position of the rearview mirror.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
