Description

Technical Field

[0001] The invention belongs to the technical field of automobile sunshade curtains, and in particular relates to an assembled automobile sunshade curtain driving assembly. Background Art

[0002] As a standard configuration of many cars, the car sunroof is installed on the car roof, which can effectively circulate air in the car, increase the intake of fresh air, and bring healthy and comfortable enjoyment to the car owner. At the same time, the car window can also broaden the field of vision, and is also often used for mobile photography and video shooting needs to avoid discomfort to passengers due to direct sunlight in the hot summer. Common sunshades are electric and manual. Electric sunshades require a special drive assembly to achieve, and the sunshade drive assembly is an extremely important structure in the car sunroof.

[0003] The existing drive assembly mainly relies on the motor to drive the shaft to achieve rotation. Once the sunshade is damaged, in order to reduce the damage, the motor needs to stop rotating to avoid continuing to reel in or release the sunshade. However, the shaft will continue to rotate due to the inertia of the speed, and the purpose of stopping cannot be achieved. Therefore, there are great limitations in actual use and there is room for improvement. Summary of the invention

[0004] The object of the present invention is to provide an assembled automobile sunshade drive assembly to solve the problem that the existing drive assembly mentioned in the above background technology cannot achieve the instant stop function according to the use requirements.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an assembled automobile sunshade drive assembly, comprising a motor, a shaft for winding the sunshade is installed on the output end of the motor, a shell for allowing the sunshade to enter and exit is sleeved on the outside of the shaft, and the rear part of the shell is installed on the vehicle frame; two mounting seats are provided and distributed at both ends of the shaft, one of which is fixedly installed with the motor, and a mounting sleeve is fixed on the inner wall of the mounting seat, and the mounting sleeve is sleeved on the end of the shaft; an instant stop component is provided inside the mounting sleeve, and the instant stop component includes a rotating part and a limiting part, which are meshed and connected, and the mounting sleeve is fixedly installed ... the mounting sleeve is provided with a stop component inside, and the stop component includes a rotating part and a limiting part, which are meshed and connected, and the stop component is provided with a stop component. The middle rotating member is arranged concentrically with the mounting sleeve and is sleeved on the shaft; the limiting member includes a low-speed motor mounted on the inner side of the mounting seat, and a limiting gear disk mounted on the output end of the low-speed motor. A gear ring is fixed on the rotating member, and the gear ring is meshed and connected with the limiting gear disk. During the normal retraction and extension of the sunshade, the rotating member will assist the rotation of the shaft to reduce friction. When it is necessary to stop the rotation immediately, the low-speed motor is started and is in standby mode. At this time, the low-speed motor cannot be driven by the gear ring, so the gear ring is stopped by the limiting gear disk, and the purpose of stopping the entire rotating member is achieved.

[0006] As a preferred technical solution in the present invention, the rotating part includes a bearing, which is composed of an inner ring, an outer ring, and balls arranged between the inner and outer rings, wherein the inner ring is fixedly fitted on the shaft to achieve the purpose of synchronous rotation and synchronous stop of the two.

[0007] As a preferred technical solution in the present invention, the inner ring portion of the bearing protrudes toward the motor and forms an extension portion, an annular groove is provided on the outer side of the end of the extension portion, and the gear ring is sleeved in the annular groove.

[0008] As a preferred technical solution in the present invention, the gear ring and the ring groove are welded and fixed to achieve stable installation of the two. The thickness of the gear ring is equal to the inner width of the ring groove to avoid protrusion affecting subsequent installation and use.

[0009] As a preferred technical solution in the present invention, a mounting plate is also provided between the two mounting seats, on which a plurality of built-in lithium battery type micro cameras are equidistantly installed. The built-in lithium battery type micro cameras are located directly below the sunshade. The surface of the sunshade is detected by the built-in lithium battery type micro cameras. Once the surface of the sunshade is damaged, the information is transmitted to the vehicle computer in time to ensure that the subsequent sunshade effect is not affected.

[0010] As a preferred technical solution in the present invention, a through groove is provided on the surface of the mounting seat for the end of the mounting plate to pass through, so as to realize the assembly and installation of the mounting seat and the mounting plate.

[0011] As a preferred technical solution in the present invention, limiting plates are fixed at both ends of the mounting plate, and the top of the limiting plate extends obliquely toward the middle of the mounting plate. The top of the limiting plate exceeds the through-slot and abuts against the outer side surface of the mounting seat, thereby ensuring that the mounting plate and the mounting seat will not fall off after assembly. The limiting plate is made of plastic or metal, can be deformed after passing through the through-slot, and can be pressed against the outer wall of the mounting seat by rebounding in the later stage.

[0012] As a preferred technical solution in the present invention, the mounting seat is L-shaped as a whole, and the mounting seat is fixed to the frame by bolts.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The designed instant stop component can quickly lock the shaft of the rolling sunshade in an emergency, preventing the shaft from continuing to rotate due to inertia and avoiding further damage. At the same time, when the instant stop component is not in use, it can also increase the rotation rate of the shaft and reduce the friction generated during rotation, thereby improving the shortcomings of the existing structure in use.
