Description

Technical Field

[0001] This utility model belongs to the field of rearview mirror technology, and in particular relates to a retractable and adjustable rearview mirror auxiliary mirror. Background Technology

[0002] Rearview mirrors are an important safety component of motor vehicles. Their main function is to provide drivers with information about the road conditions behind them when reversing and to assist drivers in observing the surrounding environment while driving.

[0003] Traditional rearview mirrors are often installed in a fixed manner, and their mirror angle and field of vision remain unchanged after installation. This means that the driver's field of vision mainly covers the area behind the vehicle, while the areas to the sides and near the front wheels become blind spots. In complex driving scenarios such as inclement weather, narrow roads, or sharp turns, this structural defect is further amplified. Because the fixed field of vision cannot adapt to the road conditions required in complex driving scenarios, it is difficult for the driver to fully perceive the surrounding environment and wheel position, resulting in increased driving safety risks. Summary of the Invention

[0004] To address the shortcomings of existing technologies, a retractable and adjustable rearview mirror auxiliary mirror is provided.

[0005] This utility model is achieved using the following technical solution:

[0006] A telescopic adjustable rearview mirror auxiliary mirror includes a fixing part for mounting on the rearview mirror. A telescopic beam is pivotally connected to the fixing part, and an auxiliary mirror is universally connected to one end of the telescopic beam away from the fixing part. The telescopic beam includes a sleeve and a support rod that are nested together. At least two rows of positioning grooves are symmetrically arranged along the length direction of the support rod. The sleeve is provided with positioning blocks for cooperating with the positioning grooves. When the positioning blocks are embedded in the positioning grooves, the length of the telescopic beam can be fixed.

[0007] The fixing part can be a claw-type structure that is used to snap into the gap between the lens and the frame of the rearview mirror, or a flat adhesive structure that is glued to the bottom of the rearview mirror, or a combination of both.

[0008] The auxiliary mirror can have a convex or concave surface.

[0009] In use, the driver installs the fixing part on the rearview mirror, adjusts the positioning block and its corresponding positioning groove to make the telescopic beam at the appropriate length, and then adjusts the angle of the auxiliary mirror so that the auxiliary mirror is positioned close to the rearview mirror, so that the auxiliary mirror and the rearview mirror are in the same field of vision area of ​​the driver, increasing the driver's field of vision and making its angle adjustable, making it easier for the driver to see, thereby making it easier for the driver to perceive the surrounding environment and the position of the wheels.

[0010] Preferably, the housing has a receiving space for accommodating the support rod, and the receiving space forms a first slide for sliding and limiting the support rod, thereby providing space for the support rod to slide relative to each other.

[0011] Preferably, the end of the sleeve corresponding to the opening of the positioning groove has a hollowed-out portion. The hollowed-out portion is connected to the first slide and is U-shaped. The hollowed-out portion divides this end of the sleeve into a fixed shell and a movable shell. The movable shell forms a positioning clip for cooperating with the positioning groove. The positioning clip has a positioning block at one end near the positioning groove.

[0012] The shell is made of a material with elastic deformation capability.

[0013] The structural strength of the back of the casing is reduced by the hollowed-out part, so that the positioning card can swing relative to the positioning block to insert into the positioning groove or disengage from the positioning groove.

[0014] Preferably, when the positioning block is in its normal state, the length of the telescopic beam can be changed by actively pulling the casing and / or support rod to disengage the positioning block from the positioning groove.

[0015] By controlling the extension or shortening of the telescopic beam solely through active traction of the housing and / or support rod, compared to the method of manually controlling the extension and shortening by opening the positioning clip, it is easier for the driver to adjust with one hand.

[0016] Preferably, the fixed housing or the movable housing is provided with a dividing fin at the central axis position, thereby increasing the number of contact surfaces between the positioning clip and the support rod, and thus increasing the friction between the positioning clip and the support rod.

[0017] Preferably, the support rod is provided with a second slide rail that divides the positioning groove. The second slide rail is a through cavity and makes the support rod have a fork-shaped structure. The dividing fin can slide within the second slide rail, thereby forming a composite double slide rail structure to slide and limit the support member.

[0018] Preferably, one end of the support rod facing the sliding direction of the housing is the front end of the second slide, and the other end of the second slide is the rear end. Two protrusions are symmetrically provided on the inner wall of the front end of the second slide for limiting the segmented fin, thereby using the protrusions to limit the end point of the sliding stroke of the support fin.

[0019] Preferably, the support rod has chamfers at both ends in the width direction corresponding to the protrusion to reduce the structural strength at that point.

[0020] The support rod is made of a material with elastic deformation capability.

[0021] By setting chamfers on both sides of the front end of the support rod, the local structural strength is reduced, which makes it easier for the support rod to expand and deform to both ends; and the chamfered surface and the side wall of the accommodating space form an active space for the support rod to be opened by the segmented fins, which facilitates the assembly and disassembly of the support rod and the casing.

[0022] Preferably, the fixing part is a claw-type structure with at least one flat end. The surface of the flat end is used to set an adhesive, thereby realizing a composite fixing of the fixing part by snapping and bonding, and improving the installation strength of the fixing part and the rearview mirror.

[0023] Preferably, the housing and the auxiliary mirror are connected by a universal ball joint.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] A telescopic beam is formed by a relatively telescopic support rod and a housing, and is equipped with a universal ball joint. This allows the auxiliary mirror's field of vision to be adjusted while fixing the auxiliary mirror to the rearview mirror, forming an external mounting mechanism for the rearview mirror. This seamlessly integrates the vehicle's side and wheel-side field of vision into the driver's field of vision, making it easier for the driver to fully perceive the surrounding environment and wheel position, thus reducing driving safety risks.

[0035] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0036] Example 1

[0037] like Figures 1 to 8 As shown, this embodiment discloses a telescopic adjustable rearview mirror auxiliary mirror, including a fixing part 11 for mounting on the rearview mirror. The fixing part 11 is a claw-type structure with a flat end 12 and a curved end 13. The curved end 13 can be inserted into the gap between the rearview mirror lens and the housing, and cooperate with the flat end 12 for clamping and fixing. The surface of the flat end 12 is used to set an adhesive to securely attach it to the rearview mirror (not shown in the figure).

[0038] A telescopic beam 14 is pivotally connected to the fixing part 11. The telescopic beam 14 includes a sleeve 20 and a support rod 30 that are nested together. The support rod 30 has two rows of positioning grooves 31 arranged symmetrically along the length of the support rod 30. The sleeve 20 has positioning blocks 28 for cooperating with the positioning grooves 31. When the positioning blocks 28 are embedded in the positioning grooves 31, the length of the telescopic beam 14 can be fixed. An auxiliary mirror 16 is universally connected to the outer surface of the sleeve 20 away from the fixing part 11 through a universal ball joint 15. The universal ball joint 15 has the same structure as the prior art.

[0039] The housing 20 has a receiving space 24 for accommodating the support rod 30, and the receiving space 24 forms a first slide 26 for sliding and limiting the support rod 30.

[0040] The end of the sleeve 20 corresponding to the opening of the positioning groove 31 is provided with a hollow part 21. The hollow part 21 is connected to the first slide 26 and is U-shaped. The hollow part 21 divides this end of the sleeve 20 into a fixed shell 23 and a movable shell 22 that can move elastically. The movable shell 22 constitutes a positioning clip, and its inner side is provided with a positioning block 28 that cooperates with the positioning groove 31.

[0041] In its natural state, the positioning block 28 is embedded in the positioning groove 31, thus fixing the length of the telescopic beam 14.

[0042] When the length needs to be adjusted, the user only needs to apply axial tension or thrust to the housing 20 and / or support rod 30, which will cause the movable housing 22 to undergo elastic deformation under the reaction force of the positioning block 28, thereby causing the positioning block 28 to disengage from the positioning groove 31. Then, the support rod 30 is slid to the desired position and released, and the positioning block 28 is locked back into the corresponding positioning groove 31 to realize the re-locking of the telescopic beam 14, thereby adjusting the length of the telescopic beam 14, and thus making multi-angle adjustment of the auxiliary mirror 16, so that the driver can flexibly adjust the viewing angle of the auxiliary mirror 16 and expand the field of vision.

[0043] When the positioning block 28 is in its normal state, it can be disengaged from the positioning groove 31 by active traction.

[0044] To further improve the stability of telescopic movement, a second slide rail 32 is opened inside the support rod 30 along the axial direction, so that the cross section of the support rod 30 along the length direction has a fork-shaped structure. A dividing fin 27 is provided at the corresponding position of the central axis inside the fixed shell 23 or the movable shell 22. The dividing fin 27 can slide along the second slide rail 32 during the telescopic movement of the support rod 30, and plays a guiding and anti-torsion role.

[0045] A pair of protrusions 33 are symmetrically arranged on the inner wall of the front end of the second slide 32 (i.e., the direction in which the support rod 30 extends into the housing 20) to limit the end point of the sliding stroke of the dividing fin 27 and prevent the support rod 30 from being pulled out excessively. The support rod 30 has chamfers 34 at both ends in the width direction where the protrusions 33 are located to reduce stress concentration at this point, improve structural durability, and facilitate the expansion deformation of the support rod 30 to both ends. The inclined surfaces at both ends of the chamfer 34 form an active space between the chamfers 34 and the side wall of the accommodating space 24 for the support rod 30 to be opened by the dividing fin 27, which facilitates the disassembly and assembly of the support rod 30 and the housing 20.

[0046] Example 2

[0047] The difference between this embodiment and Embodiment 1 is that the accommodating space 24 has a lateral opening along the thickness direction and an axial opening along the length direction. Two baffles 25 are symmetrically provided at the opening of the lateral opening. The baffles 25 and the side wall of the accommodating space 24 together form a first slide rail 26 for sliding and limiting the support rod 30.

[0048] The support rod 30 has a U-shaped protrusion 35 on the back side corresponding to the positioning groove 31. The protrusion 35 and the surface of the support rod 30 form an inwardly recessed step 36 for the retaining edge 25 to fit into, thereby forming a third slide, which further improves the telescopic stability of the telescopic beam 14.
