In detail, the fastener 158 passes through the second bolt hole 122 and is threadedly connected to the second bolt hole 122, so that the second rail part 120 and the first rail part 110 are fixed. The arrangement of the first rail part 110 and the second rail part 120 has good installation firmness and is easy to assemble.

[0072] Reference Figure 1 The driving device includes a driving element 140 and a transmission mechanism 150. The driving element 140 may be a motor, preferably a servo motor or a stepping motor. The transmission mechanism 150 is disposed on the base plate 100 of the vehicle door and connected to the lifting rod 130. The driving element 140 is connected to the transmission mechanism 150, so that the driving element 140 drives the lifting rod 130 through the transmission mechanism 150. The transmission mechanism 150 and the driving element 140 are integrated on the base plate 100 of the vehicle door, so that the driving device of the automotive sunshade assembly according to the utility model occupies less space in the vehicle door.

[0073] Further, see Figure 4 The transmission mechanism 150 includes a flexible shaft 151, which is passed through the driving channel and connected to the lifting rod 130. The driving element 140 drives the lifting rod 130 through the flexible shaft 151, and the setting of the flexible shaft 151 is convenient for being arranged in the driving channel and connected to the lifting rod 130. The flexible shaft 151 can be made of a material with a certain elasticity such as rubber or plastic, so as to meet the assembly requirements between the transmission mechanism 150 and the lifting rod 130.

[0074] Furthermore, the flexible shaft 151 is fixedly connected to the lifting rod 130, which is convenient for installation and maintenance.

[0075] Further, see Figure 4The transmission mechanism 150 also includes a gear box, the driving element 140 is arranged in the gear box and connected to the gear box, and the flexible shaft 151 is connected to the gear box. The gear box is used to convert the rotational movement of the driving element 140 into the movement of the flexible shaft 151, so as to realize the conversion of the driving mode between the driving element 140 and the lifting rod 130. The gear box includes a gear 153, the flexible shaft 151 is provided with a helical tooth 152, the gear 153 is meshed with the helical tooth 152 of the flexible shaft 151, and the driving element 140 is connected to the gear 153. When the driving element 140 drives the gear 153 to rotate, the gear 153 drives the flexible shaft 151 to move linearly through the helical tooth 152, so as to drive the lifting rod 130.

[0076] Reference Figure 5 The gearbox further includes a worm wheel 154 and a worm 155. The worm wheel 154 is connected to the gear 153 via a transmission shaft 159, so that the worm wheel 154 and the gear 153 are coaxial and fixed. The worm 155 is fixedly connected to the output shaft of the driving element 140, and the worm 155 is meshed with the worm wheel 154. When the driving element 140 is started, the worm 155 drives the worm wheel 154 to rotate, and the gear 153 is rotated through the transmission shaft 159, thereby driving the lifting rod 130 to move through the flexible shaft 151, thereby driving the automobile sunshade assembly.

[0077] Furthermore, the gearbox further comprises a housing 156 and a cover plate 157. The housing 156 is mounted to the substrate 100 and is formed integrally with the substrate 100, so that the drive device is better integrated into the vehicle door. Furthermore, the housing 156 is formed integrally with the first track portion 110. The driving element 140, the worm wheel 154, the worm 155 and the gear 153 are all mounted to the housing 156, and the cover plate 157 is fixed to the housing 156 by a fastener 158 to achieve the closure of the housing 156. The cover plate 157 is formed integrally with the second track portion 120, which reduces the assembly amount and helps to improve the assembly accuracy.

[0078] Optionally, the driving device further includes a hose 160, which is connected to the box 156. The hose 160 can be made of rubber, and is disposed on a side of the box 156 away from the first track portion 110, for accommodating a portion of the flexible shaft 151 passing through the box 156, to prevent the flexible shaft 151 from wearing and interfering with other components or structures of the vehicle door.

[0079] The utility model also provides a car sunshade assembly, including a sunshade body 172 and a driving device according to the above car sunshade assembly. According to the car sunshade assembly of the utility model, the space occupied in the car door can be reduced, and it is suitable for car doors with compact space.

[0080] Reference Figure 1 and Figure 6The automobile sunshade assembly also includes a support plate 170, a rolling curtain frame 171 and a sunshade body 172. The first end of the sunshade body 172 is connected to the support plate 170, and the second end of the sunshade body 172 extends to the rolling curtain frame 171. The rolling curtain frame 171 is used to store the sunshade body 172. The first end of the lifting rod 130 is passed through the drive channel, and the second end of the lifting rod 130 is connected to the support plate 170. Therefore, when the lifting rod 130 is driven by the driving element 140 to be lifted and lowered, the support plate 170 is driven, so that the sunshade body 172 can be lifted and lowered. Optionally, the support plate 170 is provided with a snap-in hole, and the lifting rod 130 is snap-fitted and fixed to the support plate 170 through the snap-in hole, which is convenient for installation and maintenance.

[0081] Furthermore, the rolling curtain frame 171 includes a shell, a rotating shaft and a coil spring, and the rotating shaft is arranged in the shell and can rotate relative to the shell. The second end of the sunshade curtain body 172 is wound around the rotating shaft, the first end of the coil spring is connected to the shell, and the second end of the coil spring is connected to the rotating shaft. When the lifting rod 130 drives the support plate 170 to rise, the sunshade curtain body 172 is wound around the rotating shaft and rises, and the coil spring is deformed as the rotating shaft rotates. When the lifting rod 130 drives the support plate 170 to descend, the coil spring recovers the deformation and drives the rotating shaft to reverse, thereby cooperating with the lifting rod 130 to wind the sunshade curtain body 172 around the rotating shaft, so as to realize the storage of the sunshade curtain body 172.

[0082] Optionally, refer to Figure 1 and Figure 6 The automobile sunshade assembly further includes a transition piece 180, the lifting rod 130 is passed through the transition piece 180, the first end of the transition piece 180 is clamped to the rolling curtain frame 171, and the second end of the transition piece 180 is used to match the first track portion 110 and the second track portion 120. In detail, the second end of the transition piece 180 is passed through the drive channel. The transition piece 180 includes two transition blocks 181, and the two transition blocks 181 cooperate to form a transition channel for passing the lifting rod 130. The two transition blocks 181 can be fixed together by clamping, or can be connected together by welding.

The first end of the driving channel extends to the transition piece 180, and the second end of the driving channel extends to the transmission mechanism 150. The hose 160 is arranged along the upper edge of the base plate 100. Due to the arrangement of the soft shaft 151, the arrangement positions of the driving element 140 and the transmission mechanism 150 are relatively flexible, which facilitates the adaptation of the driving device of the automobile sunshade assembly according to the utility model to different vehicle models.

[0088] Third embodiment

[0089] Figure 8 The third embodiment shows a vehicle sunshade assembly and a driving device, which differs from the first embodiment in that the structure of the transmission mechanism 150 is different.
