Description

Technical Field

[0001] This application belongs to the field of automotive parts technology, specifically a dual-purpose blind spot rearview mirror. Background Technology

[0002] Rearview mirrors are one of the main accessories of a car. They are used to observe the condition of vehicles behind the car while driving normally, and also to observe the situation behind the car when reversing. However, existing rearview mirrors have a certain blind spot, so many drivers install additional blind spot mirrors to increase their field of vision.

[0003] A blind spot mirror is an auxiliary device used to increase a driver's field of vision, helping them better observe blind spots around the vehicle. It is typically mounted on the side mirrors of a car to supplement areas not directly covered by the side mirrors. The purpose of a blind spot mirror is to provide additional visibility, helping drivers better observe traffic conditions to the sides and rear, and reducing safety hazards caused by blind spots.

[0004] Among commercially available blind spot rearview mirrors, two types are commonly used. The first type is directly attached to the rearview mirror as part of it, such as the blind spot rearview mirror disclosed in Chinese Patent CN218594237U. This design uses a suction cup to attach to the mirror surface, and by rotating the outer shell, the shell is pressed down to squeeze out air, thus stabilizing the blind spot rearview mirror on the rearview mirror. The second type incorporates an extended design to reduce the space occupied by the rearview mirror, such as the rotatable blind spot auxiliary mirror disclosed in Chinese Patent CN207059905U. This design uses an S-shaped pivot to extend the spherical mirror, allowing the spherical mirror to extend further outside the rearview mirror, thus expanding the field of vision while reducing the area occupied by the rearview mirror surface.

[0005] However, currently, when drivers purchase blind spot rearview mirrors, they may initially buy the first type but then find it takes up too much space and want the second type, requiring them to purchase the second type separately; or they may initially buy the second type but find it lacking in aesthetics and want the first type, requiring them to purchase the first type separately. Therefore, to meet the different installation needs of drivers, there is an urgent need for a blind spot rearview mirror that can accommodate both installation methods. Utility Model Content

[0006] The purpose of this application is to provide a dual-purpose blind spot rearview mirror that can provide two installation methods to meet different installation needs.

Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] Example 1

[0028] refer to Figures 1-3A dual-purpose blind spot rearview mirror includes a suction cup assembly 1, a connecting rod 2, a housing 3, and a lens assembly 4. The suction cup assembly 1 has a connecting part on the side facing away from its suction surface. The housing 3 is threadedly connected to the connecting part. The housing 3 can be moved along the axis of the suction cup assembly 1 by rotation. The connecting rod 2 is S-shaped. One end of the connecting rod 2 has a ball end 21, and the other end has a ball seat end 22 that matches the ball end 21.

[0029] The end of the connecting part away from the suction cup assembly 1 has a first ball joint connector 123, and the side of the lens assembly 4 facing away from its mirror surface has a second ball joint connector 421. The first ball joint connector 123 and the second ball joint connector 421 are complementary structures, and the lens assembly 4 can be connected to the first ball joint connector 123 through the second ball joint connector 421.

[0030] This embodiment only describes the first installation method, i.e., without using the connecting rod 2. In this design, the driver can directly connect the second ball joint connector 421 of the lens assembly 4 to the first ball joint connector 123 on the connecting part of the suction cup assembly 1. In a preferred embodiment, the first ball joint connector 123 can be a ball head 1231, and the second ball joint connector 421 can be a ball seat 4211. In other embodiments, the first ball joint connector 123 is a ball seat 4211, and the second ball joint connector 421 is a ball head 1231. Both methods connect the ball head 1231 and the ball seat, providing the lens assembly 4 with swing and rotation functions. After the lens assembly 4 and the suction cup assembly 1 are installed, the blind spot rearview mirror is mounted on the mirror surface of the car rearview mirror using the suction cup assembly 1.

[0031] Furthermore, the suction cup assembly 1 includes a suction cup 11 and a connecting piece 12. The side of the suction cup 11 facing away from its adsorption surface has an adhesive coating 111. The middle part of the connecting piece 12 has a connecting post 121. The connecting post 121 and the connecting piece 12 are arranged coaxially. The outer peripheral wall of the connecting post 121 has an external thread 122. The connecting piece 12 is connected to the adhesive coating 111. The connecting post 121 is a connecting part. The first ball-head connector 123 is located at the end of the connecting post 121. The outer shell 3 is threadedly connected to the connecting post 121.

[0032] Specifically, the rubber-coated part 111 can be integrally formed during the molding of the suction cup 11. Regarding the connection method between the connecting piece 12 and the rubber-coated part 111, it can be achieved by bonding, integral injection molding, or bolt connection. Specifically, in the bolt connection, a nut is wrapped inside the rubber-coated part 111, and the connecting piece 12 has multiple circumferentially arranged mounting holes. A bolt passes through the mounting holes and connects to the nut. Alternatively, a blind hole with threads can be provided inside the rubber-coated part 111, and a bolt passes through the mounting hole and connects to the blind hole in the same way. The connecting post 121 and the connecting piece 12 can be integrally formed, as can the first ball-head connector 123 and the connecting post 121. After the outer shell 3 is threadedly connected to the connecting post 121, rotating the outer shell 3 allows it to move along the axial direction of the connecting post 121, thereby squeezing the suction cup 11, expelling air from the suction cup 11, and ensuring adsorption stability.

[0033] In this embodiment, the bottom middle region of the outer shell 3 has an upwardly recessed receiving portion 31, and the middle part of the outer shell 3 also has a through hole 32, which communicates with the receiving portion 31. The diameter of the through hole 32 is smaller than the inner diameter of the receiving portion 31, and the inner diameter of the receiving portion 31 is smaller than the outer diameter of the outer shell 3. The receiving portion 31 is used to receive the rubber-coated portion 111. The inner peripheral wall of the through hole 32 has an internal thread 33, and the outer shell 3 is threadedly connected to the connecting post 121 through the internal thread 33.

[0034] Specifically, the receiving part 31 and the bottom of the outer shell 3 can be matched with the upper surface of the suction cup 11 and the rubber coating part 111. When rotating the outer shell 3, in the optimal state, the bottom of the outer shell 3 can simultaneously contact and press against the upper surface of the suction cup 11. Furthermore, the outer peripheral wall of the outer shell 3 has anti-slip texture. The anti-slip texture 34 can improve the comfort of rotating the outer shell 3.

[0035] Preferably, the lens assembly 4 includes a lens 41 and a lens holder 42, with the side of the lens 41 facing away from its mirror surface connected to the lens holder 42, and the second ball joint connector 421 located in the middle of the lens holder 42.

[0036] In practical use, the side of the lens 41 facing away from its mirror surface and the lens holder 42 can be connected by adhesive bonding, and the second ball joint connector 421 and the lens holder 42 can be integrally formed.

[0037] Preferably, the shape and size of the ball head 1231 match the shape and size of the ball head end 21, and the shape and size of the ball seat portion 4211 match the shape and size of the ball seat end 22. Specifically, the design of matching the shape and size of the ball head 1231 and the ball head end 21 ensures the uniformity of the two ball heads, while the design of matching the shape and size of the ball seat portion 4211 and the ball seat end 22 ensures the uniformity of the two ball seats, ensuring that the ball head 1231 and the ball seat end 22 can also be connected, and the ball head end 21 and the ball seat portion 4211 can also be connected.

[0038] Example 2

[0039] refer to Figures 4-6 In this embodiment, the lens assembly 4 is connected to one end of the connecting rod 2 via the second ball joint connector 421, and the other end of the connecting rod 2 is connected to the first ball joint connector 123, as a second installation method.

[0040] Specifically, similar to Embodiment 1, if the first ball joint connector 123 is a ball head 1231, then the second ball joint connector 421 is a ball seat portion 4211; if the first ball joint connector 123 is a ball seat portion 4211, then the second ball joint connector 421 is a ball head 1231; it is only necessary to ensure that the first ball joint connector 123 and the second ball joint connector 421 are complementary. In this embodiment, the first ball joint connector 123 is a ball head 1231 and the second ball joint connector 421 is a ball seat portion 4211. Then the ball head 1231 is connected to the ball seat end 22, and the ball seat portion 4211 is connected to the ball head end 21, thereby extending the lens assembly 4.

[0041] In other embodiments, for the mounting method of this embodiment, the lens 41 can also adopt other shapes besides circle, such as heart, rectangle, square, etc.

[0042] In the above embodiments 1 and 2, the connection between the ball head 1231 and the ball seat end 22, and the connection between the ball seat part 4211 and the ball head end 21 are all detachable and movable connections. Those skilled in the art can directly understand them as ball-and-socket joint structures, that is, the ball head 1231 can rotate and swing within the ball seat end 22 within an allowable range, and so can the ball seat part 4211 and the ball head end 21.

[0043] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of this application, and these improvements or modifications should also be considered within the scope of protection of this application.
