Description

Technical Field

[0001] The utility model relates to the technical field of automobile sun visors, in particular to a suspension and holding mechanism for a heavy-weight sun visor. Background Art

[0002] Cars are often equipped with sun visors to block sunlight, preventing it from glaring the driver and affecting driving safety. During use, the sun visor can rotate relative to a shaft mounted on the car to adjust the shading angle. A retaining mechanism is installed within the sun visor, which cooperates with the shaft through friction to fix the angle of the sun visor.

[0003] Currently, the retaining mechanism installed in a car sun visor includes a housing and a mounting plate. A rotating shaft runs through the housing, and the mounting plate is connected to a pressure plate via a spring. The pressure plate abuts the rotating shaft under the action of the spring, and the friction between the pressure plate and the rotating shaft is used to fix the angle of the sun visor. However, in actual use, the housing is only fixed to the sun visor body at one end. When encountering bumps, the housing will shake relative to the sun visor body, producing abnormal noise and poor hovering effect. If the sun visor body falls freely while the car is driving, it will obstruct the driver's vision, easily causing safety accidents and posing a serious safety hazard. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a heavy-weight sun visor suspension and retention mechanism with high stability, high structural strength, and easy installation and use.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A heavy-weight sun visor suspension and holding mechanism, comprising a shell and a suspension and holding structure; the shell is U-shaped and has an open end at one end, the inner side surface of the shell away from the open end is contoured to the rotating shaft, and two ears extend outward from one side of the open end of the shell, and the ears are penetrated by a mounting hole, and the shell is fixedly connected to the sun visor body by screws; the suspension and holding structure comprises a fixed stopper, a plurality of springs and a movable stopper, the fixed stopper and the movable stopper are arranged at both ends of the spring in the circumferential direction, the fixed stopper is fixedly installed at the opening of the shell, and the movable stopper abuts against the rotating shaft under the thrust of the spring; a plurality of plug blocks are protruding from one side of the shell, and the plug blocks are plugged into the sun visor body.

[0007] Preferably, sliders are protruding from both sides of the movable stopper, and guide grooves for sliding engagement with the sliders are provided on both sides of the housing.

[0008] Preferably, a positioning platform capable of plugging and cooperating with a spring is protruded from one side of the fixed stopper facing the movable stopper, and the diameter of the positioning platform gradually decreases in a direction approaching the movable stopper.

[0009] Preferably, two bosses are protruding from both sides of the fixed stopper, and the shell is provided with sockets that are plugged into the bosses.

[0010] Preferably, the portion of the rotating shaft located in the housing has a concave flat portion, the flat portion is a plane, and arc surfaces are provided between the two sides of the flat portion and the rotating shaft.

[0011] Preferably, both sides of the movable stopper extend toward the fixed stopper to form a rib.

[0012] In summary, this heavy-weight sun visor suspension and retention mechanism has the advantages of high stability, high structural strength, and easy installation and use. The specific effects are as follows:

[0013] 1. Add an insert to the shell to fix it to the sun visor body, increase the stress points between the hovering and holding mechanism and the frame, and improve the problem of looseness and abnormal noise of the hovering and holding mechanism on the sun visor body.

[0014] 2. Add material connection at the position where the slider is installed on the shell to increase the strength of the shell and improve the problem of abnormal noise caused by weak shell strength and twisting.

[0015] 3. The end face of the movable stopper is designed with a semicircular rib to facilitate the assembly of the movable stopper to the housing of the hovering holding mechanism.

[0016] 4. As the weight of sun visors on different models varies greatly, the number of springs can be quickly increased or decreased according to the weight of the sun visors to keep the operating force of sun visors of different weights consistent and the number of mechanisms developed.

[0022] The present invention is further described in detail below with reference to the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional terms such as "upper, lower" and "top, bottom" are generally based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. Unless otherwise indicated, these directional terms do not indicate or imply that the devices or components referred to must have a specific direction or be constructed and operated in a specific direction, and therefore should not be understood as limiting the scope of protection of the present invention; the directional terms "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0023] like Figure 1-5 As shown, a heavy-weight sun visor suspension and holding mechanism includes a shell 1 and a suspension and holding structure 2; the shell 1 is U-shaped and has an open end at one end, the inner side surface of the shell away from the open end is conformally fitted with the rotating shaft 3, and two ears 4 extend outward from one side of the open end of the shell, and the ears are penetrated by a mounting hole, and the shell is fixedly connected to the sun visor body by a screw 5; the suspension and holding structure includes a fixed stop 6, a plurality of springs 7 and a movable stop 8, and the fixed stop and the movable stop are arranged at both ends of the spring in the circumferential direction, the fixed stop is fixedly installed at the opening of the shell, and the movable stop abuts against the rotating shaft under the thrust of the spring; a plurality of plug blocks 9 are protruding from one side of the shell, and the plug blocks are plugged into the sun visor body 100.

[0024] First, the visor body is a conventional structure, consisting of a fixedly connected upper and lower shells, with a mounting area formed between them and the hovering retention mechanism located within the mounting area. Two internally threaded barrels are fixed to the visor body, and screws connect the two sides of the shell to the internally threaded barrels, achieving the connection between the shell and the visor body. The U-shaped design of the shell better positions the rotating shaft, facilitating its rotation.

[0025] The sun visor body is equipped with a socket for the plug-in block. The plug-in block is inserted into the socket and fixed to the sun visor body, increasing the stress points between the hovering and holding mechanism and the frame, and improving the problem of the hovering and holding mechanism loosening and making abnormal noises on the sun visor body.

[0026] During actual use, a plurality of springs provide squeezing force to the movable stopper, so that the movable stopper can be better pressed against the rotating shaft, thereby increasing the pressing force and friction force, and making the hovering of the sun visor body more stable and reliable.

[0027] By adjusting the number and specifications of the springs, the pressing force and the compressing elastic force can be adjusted, which can adapt to car sun visors of different qualities and solve the problem of large-quality sun visors falling freely.

[0028] During implementation, sliders 10 protrude from either side of the movable stopper, and guide grooves 11 are provided on either side of the housing to slidably engage the sliders. This facilitates the movement of the movable stopper and facilitates installation. The location where the sliders are mounted on the housing provides a material connection, increasing the housing's strength and addressing issues such as twisting and abnormal noise caused by weak housing strength.

[0029] During implementation, a positioning platform 12 capable of plugging and cooperating with the spring is protruded from one side of the fixed stopper facing the movable stopper, and the diameter of the positioning platform gradually decreases along the direction close to the movable stopper, so as to facilitate the positioning of the end of the spring.

[0030] During implementation, two bosses 12 are protruded from both sides of the fixed block, and the housing is provided with sockets that are plugged into the bosses, so as to facilitate the connection between the fixed block and the housing.

[0031] During implementation, the portion of the shaft located within the housing has a concave flat portion 13. This flat portion is flat, with arcuate surfaces formed on either side of the flat portion and the shaft. The circular shaft creates a flat portion, and when the sun visor rotates to this position, a torque is generated at the flat portion, creating a continuous holding force between the sun visor and the ceiling, keeping it in close contact with the ceiling.

[0032] During implementation, both sides of the movable stopper extend toward the fixed stopper to form a retaining edge 14, which can block and limit the spring end and facilitate the assembly of the movable stopper to the housing.

[0033] As the weight of sun visors on different models vary greatly, the number of springs can be quickly increased or decreased according to the weight of the sun visors to keep the operating force of sun visors of different weights consistent and the number of mechanisms developed.

[0034] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention is intended to include such modifications and variations.
