Description

Technical Field

[0001] This utility model relates to the field of automotive sunshade equipment, and in particular to an adjustable folding frame for automotive sunshades. Background Technology

[0002] As car ownership becomes more prevalent in households, the temperature inside a car rises rapidly under the sun when parked outdoors in the summer, which can accelerate the aging of interior components. After the vehicle is started, a lot of energy is needed to cool it down, so most users choose to install a sunshade on the roof.

[0003] The applicant designed a car sunshade frame (patent number: 201010206352.4), which, together with the awning fabric, forms an electrically foldable sunshade. However, in actual use, it was found that due to the gear meshing clearance, as the number of times the frame is opened and closed increases, the clearance error gradually accumulates, eventually causing the frame to be unable to fully retract into the cover plate. The incompletely folded frame is supported between the cover plate and the base frame, causing the sunshade cover plate to be pushed upward, forming gaps between it and the base frame and adjacent cover plates, affecting the daily use of the sunshade.

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model proposes an adjustable folding frame for a car sunshade, see reference. Figure 1 , 2The system includes a base frame 1, with a drive shaft 11 at both the front and rear ends of the base frame 1. Several first shaft gears 12 are fixed at both ends of the drive shaft 11. A drive motor 13 is connected to the drive shaft 11, and the drive motor 13 is used to drive the drive shaft 11 to rotate.

[0029] Two cover plates 2 are provided, which rotate synchronously with the drive shaft 11. The rotation of the drive shaft 11 can open the cover plates 2 to the sides or close them inward. Several rotating shafts 21 are rotatably connected to the cover plates 2. An outward flipping rod 22 is fixed on the rotating shaft 21. Second shaft gears 211 are provided at both ends of the rotating shaft 21. A synchronous shaft 23 is provided between adjacent rotating shafts 21. Third shaft gears 231 are provided at both ends of the synchronous shaft 23. The second shaft gears 211 mesh with the third shaft gears 231.

[0030] See Figure 4 , 5 An adjusting assembly 3 is provided between the drive shaft 11 and the rotating shaft 21. The adjusting assembly 3 includes an adjusting rod 31, a drive shaft gear 32, and a sleeve 33. The drive shaft gear 32 is rotatably connected to the cover plate 2 and meshes with the first shaft gear 12. A splined shaft 321 is provided on the drive shaft gear 32. The sleeve 33 is slidably connected to one end of the adjusting rod 31. The sleeve 33 and the adjusting rod 31 rotate synchronously. In use, the... The sleeve 33 is sleeved on the spline shaft 321. The sleeve 33 has a groove that matches the spline shaft 321 so as to realize the synchronous rotation of the sleeve 33 and the spline shaft 321. The other end of the adjusting rod 31 is provided with a fourth shaft gear 311. The fourth shaft gear 311 meshes with the second shaft gear 211. Through the meshing transmission of the aforementioned gears, the rotation of the transmission shaft 11 is transmitted to the rotating shaft 21 through the adjusting rod 31, and the rotation of the rotating shaft 21 flips the outward flipping rod 22 outward or inward.

[0031] If cover 2 does not close properly, the user can adjust cover 2 to... Figure 1 In the upright position shown, the adjusting component 3 is exposed on the cover plate 2. The user pulls up the sleeve 33 to disengage it from the spline shaft 321, and then rotates the adjusting rod 31 by a certain angle, usually one tooth. The adjusting rod drives the rotating shaft to rotate, which in turn drives the outward flip rod 22 to rotate in the folding direction by a certain angle. This manually eliminates the angle error accumulated during use, ensuring that the outward flip rod 22 can be completely hidden inside the cover plate 2 again, preventing the cover plate 2 from bulging upward and creating gaps. After adjustment, the sleeve 33 is re-attached to the spline shaft 321, and the frame can be reused.

[0032] See Figure 2 , 45. A connecting housing 14 is fixed to the end side of the drive shaft 11. The connecting housing 14 is composed of two half-housing parts spliced ​​together. The connecting housing 14 is fixedly connected to the cover plate 2. A rotating groove 141 is provided inside the connecting housing 14. The drive shaft gear 32 is rotatably connected to the rotating groove 141. A bearing groove can be provided in the rotating groove 141. A rotating bearing is provided on the drive shaft gear 32. The rotational connection effect between the two is achieved through the cooperation of the rotating bearing and the bearing groove. A clearance hole 142 is provided on one side of the rotating groove 141. The first shaft gear 12 that meshes with the drive shaft gear 32 is located in the clearance hole 142.

[0033] See Figure 4 A rotating seat 15 is fixed on the base frame 1, and the drive shaft 11 passes through the rotating seat 15. The drive shaft 11 can rotate relative to the rotating seat 15. A rotating shaft hole 143 is provided in the connecting housing 14. Specifically, the cross-sections of the drive shaft 11 and the rotating shaft hole 143 are corresponding polygons, thereby keeping the rotation of the drive shaft 11 and the rotating shaft hole 143 synchronized. A relief groove 144 is provided on the connecting housing 14, and the rotating seat 15 is located in the relief groove 144. The rotating seat 15 can prevent the connecting housing 14 from sliding along the axial direction of the drive shaft 11. The relief hole 142 connects the rotating groove 141 and the relief groove 144. The first shaft gear 12 is located on the side of the rotating seat 15 near the relief hole 142.

[0034] See Figure 2 The base frame 1 is provided with a snap-fit ​​groove 16, and a decorative shell 17 is inserted into the snap-fit ​​groove 16. The decorative shell 17 is arranged around the cover plate 2. When the decorative shell 17 ages, the user can remove it from the base frame 1 and replace it.

[0035] See Figure 6 Each of the rotating shafts 21 is provided with a positioning seat 24 on both sides. The positioning seat 24 is composed of two parts that are joined together. The positioning seat 24 is fixedly connected to the cover plate 2. The positioning seat 24 is provided with a meshing cavity 241. The second shaft gear 211 and the third shaft gear 231 extend into the meshing cavity 241 from both sides and remain meshed.

[0036] See Figure 5 The surface of the adjusting rod 31 is provided with a plurality of positioning protrusions 312, which are arranged along the long axis of the adjusting rod 31. The sleeve 33 is provided with a positioning groove 331. By the engagement of the positioning protrusions 312 and the positioning groove 331, the rotation of the adjusting rod 31 and the sleeve 33 is synchronized. There is a certain gap between the positioning protrusions 312 and the positioning groove 331, so that the sleeve 33 can slide up and down along the positioning protrusions 312.

[0037] See Figure 5 Torsion springs 18 are fitted at both ends of the drive shaft 11. One end of the torsion spring 18 is inserted into the connecting housing 14, and the other end of the torsion spring 18 abuts against the base frame 1. When the frame is unfolded, the torsion spring 18 is in a torsional state. When the awning is blown by the wind, the torsion spring 18 can absorb the overturning force generated by the wind on the frame, share the pressure borne by the gear transmission structure, and reduce gear wear. When there is no wind, the torsion spring 18 can drive the drive shaft 11 to rotate, compensate for the gap between the gear meshing, and ensure the compactness of the frame after unfolding. When the umbrella is closed, the torsion spring 18 can drive the drive shaft 11 to rotate, reduce the output pressure of the motor, and extend the service life of the motor.

[0038] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
