[0002] A sunshade is used to effectively block the sunlight on the windshield and windows of a car. The sunshade is installed on the window and is opened to block the sunlight in a folded state. Chinese patent application number 202321712642.5 discloses a traction assembly for a car sunshade. It can be seen that the content describes a traction assembly for a car sunshade.

[0003] When the existing automobile sunshade traction assembly is in use, the sunshade is generally installed on the car window, and it is driven by an electric motor when opening or closing the sunshade. However, during use, the motor generally pulls the top side of the sunshade to drive the sunshade to open or close, and the bottom side of the sunshade moves with the movement of the top of the sunshade. During use, the bottom of one side of the sunshade is prone to movement problems, causing the bottom of the sunshade to get stuck. At this time, the top side of the sunshade continues to move driven by the motor, which is easy to cause pulling damage to the sunshade, reducing the service life of the sunshade. For this reason, we propose a traction assembly for an automobile sunshade. Utility Model Content

[0021] Example 1

[0022] See also Figure 1-Figure 4The utility model provides a technical solution: a traction assembly for a car sunshade, comprising a traction assembly installed on a curtain body 100, the traction assembly is located outside the curtain body 100, the traction assembly comprises a pulling member and a driving member, the driving member comprises an L-shaped frame 200 and a screw 202, when in use, the L-shaped frame 200 is installed on the car and used near the window position, a reduction motor 201 is fixedly arranged on one side of the L-shaped frame 200, when in use, the reduction motor 201 can drive the screw 202 to rotate, thereby indirectly enabling one side of the curtain body 100 to be folded closed or opened, and an upper fixing rod 203 and a lower fixing rod 202 are fixedly arranged on the other side of the L-shaped frame 200, respectively. 06. A nut seat 211 is arranged on the outside of the screw rod 202. When in use, the nut seat 211 can convert the rotary motion of the screw rod 202 into linear motion. The pulling member includes a connecting strip 212 and a connecting plate 204. A movable ring 216 is sleeved on the outside of the upper fixed rod 203. The movable ring 216 is fixedly connected to the nut seat 211 and the connecting strip 212. A large limiting ring 213 is sleeved on the outside of the lower fixed rod 206. The bottom of the connecting strip 212 is fixedly connected to the large limiting ring 213. The working end of the reduction motor 201 is fixedly connected to the screw rod 202. A plurality of sets of upper sliding rings 210 and upper fixed rings 207 are sleeved on the outside of the upper fixed rod 203. When in use The upper sliding ring 210 will slide on the upper fixed rod 203, the upper fixed ring 207 is fixed on the upper fixed rod 203, and the outer part of the lower fixed rod 206 is respectively provided with a plurality of lower sliding rings 214 and lower fixed rings 215, and the lower fixed ring 215 is fixed on the lower fixed rod 206. When in use, the lower sliding ring 214 will slide on the lower fixed rod 206, and the upper fixed ring 207, the upper sliding ring 210, the lower sliding ring 214, the lower fixed ring 215 and the curtain body 100 are fixedly connected by connecting ropes. Two sets of bearings are embedded and installed inside the curtain body 100, and both ends of the screw rod 202 are inserted into the inside of the bearings. When in use, the screw rod 202 is conveniently rotated by the bearings The connecting strip 212 is connected to the upper sliding ring 210 and the lower sliding ring 214 is connected to the upper connecting piece 300.
