[0002] A rearview mirror is a crucial component on vehicles like cars and motorcycles, primarily used to help the driver observe what's happening behind the vehicle. Rearview mirrors can be categorized into several types based on their installation location and function: Interior rearview mirror: Installed inside the vehicle, usually above the windshield in front of the driver, to help the driver observe the road conditions behind the vehicle. Exterior rearview mirror: Installed on both sides of the vehicle, usually on the outside of the doors, to help the driver observe the road conditions on either side of the vehicle. Downward-view mirror: Some vehicles are also equipped with a downward-view mirror to observe what's happening below the vehicle, which is especially helpful when reversing. Rearview mirrors should provide as wide a field of view as possible and minimize blind spots.

[0003] Many existing exterior rearview mirrors on vehicles use convex mirrors to provide a wider field of view, helping drivers observe road conditions to the sides and rear of the vehicle. However, convex mirrors have limited field of view and imaging quality. For situations requiring a wider field of view, relying solely on convex mirrors results in poor rearward visibility, with limited visibility and inaccurate observation, posing a safety hazard.

[0004] In summary, how to effectively solve the problems of limited field of view and imaging effect of convex rearview mirrors is an issue that technicians in this field urgently need to solve. Utility Model Content

[0027] The core of the utility model is to provide a rearview mirror, which has both a convex mirror and a special convex mirror, has a wider field of view, and can better remind the driver of the position of the far point behind.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Please refer to Figures 1 to 3 , Figure 1 A schematic structural diagram of a rearview mirror provided in a specific embodiment of the present invention; Figure 2 It is a structural diagram of a small mirror frame; Figure 3 Schematic diagram of the structure of the block.

[0030] In a specific embodiment, the rearview mirror provided by the present invention includes a frame 12 installed on a bracket 1 and having a cavity, a convex mirror lens 9 installed on the front of the frame 12, and two sealing blocks 7 inserted into the sockets at both ends of the frame 12. The two sealing blocks 7 form a vertical receiving groove in the cavity, and the frame 12 is vertically provided with a plug-in port connected to the receiving groove; it also includes a small frame 4 connected to the receiving groove from the plug-in port and a special convex mirror lens 5 installed on the front of the small frame 4. The small frame 4 is vertically telescopically connected to the receiving groove to switch the small frame 4 to be built into the receiving groove and extended from the plug-in port.

[0031] In the above structure, the rearview mirror includes a frame 12, a convex lens 9, two sealing blocks 7, a small frame 4, and a special convex lens 5. One end of the bracket 1 is connected to the vehicle body, and the other end is provided with a threaded hole. A spherical hole is provided in the fixing block 2. The ball of the spherical fastener 10 is connected to the spherical hole of the fixing block 2, and the threaded end is connected to the threaded hole. The fixing block 2 and the bracket 1 form a rotational connection, allowing the installation position of the rearview mirror to be adjusted as needed to accommodate different observation requirements. The frame 12 is processed from a profile, and the back of the frame 12 is provided with screw holes. The fixing block 2 and the back of the frame 12 are connected by fasteners 10. The connection is detachable, making it easy to disassemble and repair.

[0032] The frame 12 has a cavity that runs through in the horizontal direction and forms a socket at each end. A sealing block 7 is connected to each of the sockets on both sides, that is, the sealing block 7 and the socket are plugged into each other. After plugging, the sealing block 7 and the frame 12 are connected at the front or back side via fasteners 10, completing the sealing of the socket by the sealing block 7.

[0033] The convex lens 9 is mounted on the front of the frame 12. Specifically, adhesive is applied to the frame 12, and the convex lens 9 is placed inside and pressed firmly. Once the adhesive solidifies, the convex lens 9 and frame 12 are connected. A convex mirror, also known as a convex surface mirror, is a mirror that reflects outward. Rearview mirrors use convex mirrors to provide a wider field of view, helping the driver observe road conditions on both sides of the vehicle.

[0034] The two sealing blocks 7 form a vertical receiving groove in the cavity. The frame 12 is vertically provided with an insertion and extraction port, which is connected to the receiving groove. The small frame 4, together with the special convex lens 5, enters the receiving groove through the insertion and extraction port and is connected to the receiving groove. In addition, the small frame 4 is movably connected to the receiving groove, and the small frame 4 can be vertically telescopically raised and lowered relative to the receiving groove. When the special convex lens 5 is in use, the small frame 4 rises and extends outward from the insertion and extraction port. When the special convex lens 5 is not in use, the small frame 4 descends and is stored in the receiving groove. This is convenient for operation, not only ensuring the normal use of the special convex lens 5, but also protecting the special convex lens 5 and reducing the contamination of the special convex lens 5 by dust and dirt. The structure is compact and does not take up excess space.

[0035] Specifically, the special convex mirror lens 5 is installed on the front of the small frame 4 and can also be connected by adhesive. The special convex mirror lens 5 is parallel to the convex mirror lens 9. Compared with the convex mirror lens 9, the special convex mirror lens 5 has a smaller curvature radius, the image reduction degree may be greater, and the field of view is wider. It is suitable for specific models or specific occasions that require a larger field of view, such as coupe-type SUVs or in narrow environments such as parking lots and communities. The observation distance is farther and clearer, and it is easier to remind the driver of the situation at a farther point behind.

[0036] The rearview mirror provided by the present invention superimposes a conventional convex lens 9 and a special convex lens 5 with a wider viewing angle, which can not only help the driver observe the situation behind and to the side of the vehicle, reduce blind spots, and improve driving safety; it is also suitable for specific car models or occasions with a larger field of view, providing a wider and deeper field of view, and helping the driver to better grasp the situation behind.

[0037] Based on the above-mentioned specific embodiments, the sealing block 7 includes an end cover connected to the socket and a rear block located on the inner side of the end cover, the rear block and the front side of the end cover form a step surface, the back side of the small frame 4 abuts against the front side of the rear block, and the two side surfaces of the small frame 4 respectively abut against the inner end surfaces of the end covers on both sides.

[0038] In one specific embodiment, the sealing block 7 includes an end cap and a rear block. The end cap matches the shape and size of the socket and seals the socket. The rear block is located inside the end cap, within the receiving groove. The rear block and end cap can be integrally formed, such as by injection molding, or they can be processed separately and subsequently connected by a mechanical connection method such as bolts.

[0039] The front of the rear block is offset from the front of the end cap, and the front of the rear block is behind the front of the end cap. The rear block and the end cap form a stepped surface at the front, and the small frame 4 is connected to the stepped area surrounded by the front of the rear block and the end face of the end cap. The back of the small frame 4 abuts the front of the rear block, and the rear block limits the front and back of the small frame 4, reducing the back and forth movement of the small frame 4. The two side faces of the small frame 4 respectively abut the inner end faces of the two end caps, limiting the left and right positions of the small frame 4, preventing the small frame 4 from rocking left and right, improving the stability of the small frame 4, protecting the special convex lens 5, and ensuring the imaging stability of the special convex lens 5.

[0040] On the basis of the above-mentioned specific embodiments, a vertical slide bar is provided on the front of the rear block, and a slide groove is provided on the back of the small mirror frame 4, and the slide bar is slidably connected to the slide groove.

[0041] In a specific embodiment, the slide bar of the rear block and the slide groove of the small frame 4 are snap-connected, and the small frame 4 moves up and down along the slide bar of the rear block, which has a good guiding effect and the small frame 4 is not easy to deviate or tilt.

[0042] In a preferred embodiment, the slide groove is a dovetail groove or a cylindrical groove or other similar structure, that is, the opening size of the slide groove is smaller than the maximum size of the slide groove, the shape of the slide bar corresponds to the shape of the slide groove, and the slide groove has a limiting effect on the slide bar. After the slide groove and the slide bar are connected, they cannot be disengaged in the forward direction, preventing the small frame 4 and the rear block from separating, which is more reliable.

[0043] Based on the above-mentioned specific embodiments, a groove is provided on the bottom surface of the small frame 4, and a limiting strip 11 that matches the groove is connected to the groove. The end of the limiting strip 11 extends to the bottom of the slide groove, and the upper end of the slide is provided with a boss 6 for blocking the limiting strip 11.

[0044] In a specific embodiment, the convex limiting strip 11 is installed in the bottom groove of the small frame 4 and connected by a fastener 10. Preferably, the bottom surface of the limiting strip 11 is provided with a countersunk hole, and the fastener 10 is connected to the countersunk hole.

[0045] The sliding groove of the small mirror frame 4 is a longitudinal through groove, and both ends of the limiting strip 11 extend to the bottom of the sliding groove, and the projection of the sliding groove falls on the limiting strip 11.

[0046] A boss 6 is provided on the upper part of the slide bar, which can be set to the upper end of the slide bar. When the slide groove slides upward along the slide bar, the upper surface of the limit bar 11 abuts against the boss 6, blocking the limit bar 11, that is, blocking the slide groove, preventing the slide groove from escaping from the slide bar, that is, vertically limiting the small frame 4 to prevent the small frame 4 from sliding out of the accommodating groove.

[0047] Furthermore, the limiting strip 11 may contact with the bottom surface of the chute to directly block it; or there may be a small gap between the two to provide a small buffer space.

[0048] Preferably, the limiting strip 11 is a rubber strip, and the boss 6 and the rubber strip are in soft contact, which has a good buffering and shock-absorbing effect and reduces the impact force generated by the collision.

[0049] On the basis of the above-mentioned specific embodiments, the accommodating groove is a through groove, the height of which is equal to the sum of the heights of the small mirror frame 4 and the limiting strip 11 , and the limiting strip 11 can block the lower opening of the accommodating groove.

[0050] In a specific embodiment, the receiving groove runs through from top to bottom, and the lower end of the small frame 4 enters the receiving groove from the upper plug-in port. After the small frame 4 is received in the receiving groove, the top surface of the small frame 4 is flush with the top surface of the frame 12, and the bottom surface of the limiting strip 11 is flush with the bottom surface of the frame 12. Visually, it is no different from a conventional convex rearview mirror, does not affect the normal use of the convex rearview mirror, and has a protective effect on the convex rearview mirror, making it less likely to be damaged or lost. The limiting strip 11 just blocks the lower end opening of the receiving groove to prevent dust and other debris from entering the receiving groove.

[0051] Based on the above-mentioned specific embodiments, the inner end surface of the end cover is provided with at least two card slots 8 in the vertical direction, and the side of the small frame 4 is provided with a card block. After the small frame 4 is moved vertically and positioned, the card block is inserted into the corresponding card slot 8.

[0052] In a specific embodiment, the inner end surface of the end cap is provided with at least two card slots 8 along the vertical direction, one of which is provided when the small frame 4 is fully extended and the special convex lens 5 is fully exposed in normal use. The card block of the small frame 4 is inserted into the upper end card slot 8 to position the use state, reduce the shaking of the small frame 4 during use, and ensure that the special convex lens 5 forms a stable image. One of the card slots 8 is provided at the bottom of the end cap, that is, the state after the small frame 4 is fully stored in the storage slot, to position the storage state of the small frame 4 and reduce shaking. The card slot 8 can also be provided between the above-mentioned two card slots 8 to position the specific state of the small frame 4, such as half extended and half retracted.

[0053] It should be noted that in each positioning state, positioning can be achieved through the cooperation of one card slot 8 and a card block, or two or more card slots 8 and card blocks can be used for positioning. For example, a group of card slots 8 and card blocks can be set at the same time in each positioning state, and double and multiple positioning is safer and more reliable.

[0054] On the basis of the above-mentioned specific embodiments, the lower part of the side surface of the small mirror frame 4 is provided with a clamping foot 3 , a gap is provided between the clamping foot 3 and the body of the small mirror frame 4 , and a clamping block is provided on the clamping foot 3 .

[0055] In one specific embodiment, the small frame 4 is made of plastic or metal, and the clamping foot 3 is made of the same material as the small frame 4. Because there is a gap between the clamping foot 3 and the main body of the small frame 4, and the clamping foot 3 is elastic, when the clamping block is inserted into the clamping slot 8, the clamping foot 3 is squeezed toward the inner side of the gap, allowing the clamping block to smoothly engage the clamping slot 8. After the clamping is completed, the clamping foot 3 returns to its original position, ensuring that the clamping slot 8 and the clamping block are always engaged and the small frame 4 is accurately positioned.

[0056] In a preferred embodiment, the gap is located below the chute, and the clamping foot 3 is located outside the chute. The chute and the gap overlap in the vertical direction, which facilitates processing.

[0057] Based on the above specific embodiments, the bottom surface of the clamping foot 3 is higher than the bottom surface of the small frame 4 body, the lower end of the clamping foot 3 has a chamfer, the clamping block is a triangular block, and the tip of the triangular block is provided with an arc.

[0058] In a specific embodiment, the bottom surface of the clamping foot 3 is higher than the bottom surface of the small frame 4 body, and the bottom surface of the clamping foot 3 avoids the bottom surface of the small frame 4, and does not affect the connection between the limit strip 11 and the groove on the bottom surface of the small frame 4.

[0059] The lower end of the clamping foot 3 has a chamfer, and the lower end of the clamping foot 3 does not contact the end surface of the end cover. The small frame 4 moves smoothly along the accommodating groove, and the clamping foot 3 and the end cover are not easily scratched.

[0060] The card block is a triangular block with an arc at the tip. When the card block and the card slot 8 need to be disengaged, the card block can be disengaged from the card slot 8 by pulling it hard in the vertical direction, which is more labor-saving. In addition, during the movement, the arc contacts the end face of the end cover, so the friction is small, the movement is smooth, and the wear is small.

[0061] Based on the above-mentioned specific embodiments, there is a gap between the rear blocks of the two sealing blocks 7, the back of the small frame 4 has a stepped surface, the middle part is thicker than the edge part, the back of the edge part abuts against the rear block, and the middle part is located in the gap space between the two rear blocks.

[0062] In a specific embodiment, the distance between the two sealing blocks 7 is smaller than the length of the frame 12 . After the sealing blocks 7 are connected to the frame 12 , the rear stoppers of the two sealing blocks 7 are not connected, and there is a gap between them.

[0063] The small frame 4 has varying thicknesses, with a stepped surface on the back. The center portion is thicker and accommodates the space between the two rear blocks, with the back of the center portion abutting the back of the receiving groove. The edge portions are thinner than the center portion, with the back of the edge portions abutting the rear blocks. The back of the small frame 4 is simultaneously restrained by the receiving groove and the rear blocks, resulting in high stability.

[0064] Based on the above-mentioned embodiments, the upper end and side surfaces of the small frame 4 are connected by rounded corners at the edges. The surface of the small frame 4 is smooth and has no sharp edges, which is not likely to scratch the operator. During the upward and downward movement, the upper end is smaller than the size of the insertion port, so it will not collide with the insertion port.

[0065] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
