Description

Technical Field

[0001] This utility model relates to the field of automotive sunshade technology, specifically to a right-angle motor-driven automotive sunshade. Background Technology

[0002] A car sunroof is generally understood as a transparent or semi-transparent panel covering the top of a car. It offers a variety of benefits. A sunroof can effectively block direct sunlight, thereby reducing the temperature inside the car and providing a cool respite for the driver and passengers in the heat. In addition, it can prevent the interior trim and seats from fading and aging due to ultraviolet radiation. The transparent design of the sunroof allows passengers to see the sky, making the interior feel more spacious and bright. Some sunroofs even have adjustable transparency to adapt to various weather and lighting conditions.

[0003] The opening principle of a car sunroof mainly includes two methods: electric drive and manual drive. Electric sunroofs usually achieve opening and closing actions through the coordinated work of components such as electric motor, transmission system and sliding screw. The electric motor provides power through the transmission system and changes the direction of current to adjust the direction of rotation, thereby realizing the opening and closing function of the sunroof. Manual sunroofs rely on human operation, usually controlled by a crank or pull rope to raise and lower the sunroof.

[0004] Existing car sunshades of this type are generally not conducive to stable opening under the drive of a right-angle motor. They are not convenient for cleverly setting the sunshade on the side of the car sunroof by utilizing the characteristics of the right-angle motor. This affects the space occupied by the drive structure, the efficiency of space utilization, and the disassembly of the drive structure, which affects maintenance costs and ease of maintenance. Utility Model Content

[0005] The purpose of this utility model is to provide a car sunshade driven by a right-angle motor, so as to solve the problems mentioned in the background art, such as the car sunshade being inconvenient to open stably under the drive of a right-angle motor, the sunshade being inconvenient to cleverly set on the side of the car sunroof by utilizing the characteristics of the right-angle motor, affecting the space occupation of the drive structure, affecting the space utilization efficiency, and the inconvenience of disassembling the drive structure, which affects the maintenance cost and ease of maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a car sunshade driven by a right-angle motor, comprising a sunshade frame and limiting strips. A retractor is symmetrically installed inside the sunshade frame. A traveling strip is installed inside the sunshade frame on one side of each retractor. Limiting strips are symmetrically installed inside the sunshade frames on both sides of each traveling strip, and the traveling strips are slidably connected to the limiting strips. A sunshade curtain is provided on the surface of each retractor, extending to the surface of the traveling strips. A drive shaft is installed at both ends of each retractor, and a retractor cylinder is fitted onto the surface of one drive shaft on one side of each retractor. A right-angle motor body is installed inside the sunshade frame on one side of each drive shaft. A power shaft is installed at the output end of each right-angle motor body. A movable pulley is symmetrically installed at the top of each traveling strip, and a fixed pulley is installed at the top of the limiting strip on one side of each movable pulley.

[0007] Preferably, the surface of the winding drum is provided with steel wires, and the steel wires extend from the fixed pulley to the surface of the movable pulley.

[0008] Preferably, the surface of the power shaft is slidably fitted with slip rings, and the interior of the transmission shaft is provided with through holes.

[0009] Preferably, a locking pin is installed on the outer wall of the slip ring on one side of the through hole, and the locking pin extends into the interior of the drive shaft.

[0010] Preferably, multiple sets of springs with equal spacing are installed on the outer wall of the slip ring, and all springs are connected to the power shaft. The slip ring has symmetrically arranged grooves inside.

[0011] Preferably, a limiting key is installed on the outer wall of the power shaft on one side of the groove, and the limiting key is slidably connected to the groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the car sunshade not only realizes the stable opening of the car sunshade under the drive of the right angle motor, but also utilizes the characteristics of the right angle motor to be cleverly set on the side of the car sunroof, and greatly reduces the space occupation, optimizes the space utilization efficiency, facilitates the disassembly between the drive structure, reduces maintenance costs and facilitates maintenance.

[0013] (1) The power shaft is driven to rotate by the right-angle motor body, the power shaft drives the transmission shaft to rotate, the transmission shaft drives the winding roller to rotate, the winding roller drives the winding drum to rotate, the winding drum releases the steel wire, the steel wire is supported by the fixed pulley and the moving pulley, the steel wire drives the walking strip and the sunshade curtain to move through the moving pulley. When the winding roller releases the sunshade curtain, the steel wire pulls the walking strip and the sunshade curtain through the moving pulley to facilitate the opening of the sunshade curtain. The car sunshade curtain is opened stably under the drive of the right-angle motor. The sunshade curtain can be cleverly set on the side of the car sunroof by utilizing the characteristics of the right-angle motor, which greatly reduces the space occupation and optimizes the space utilization efficiency.

[0014] (2) When connecting the winding roller to the right-angle motor body, insert the drive shaft into the inside of the slip ring, insert the locking pin into the slip ring, through hole and drive shaft, and use the locking pin to fix the slip ring and drive shaft. The slip ring can slide left and right under the elastic support of the spring. The groove slides on the surface of the limiting key to provide limiting support, so as to facilitate the slip ring to slide back and forth and connect with the drive shaft, so as to facilitate the disassembly between the drive structure, reduce maintenance costs and facilitate maintenance.
