DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] like Figure 1-8 As shown, an electric roller sunshade for a car sunroof comprises a frame 1, a driving assembly 2 and a roller assembly 3, wherein the driving assembly 2 and the roller assembly 3 are connected to the frame 1, and the frame 1 is connected to a ceiling 11;

[0027] The reel assembly 3 includes a reel barrel 31, a large spring 32, a steel column 33, a large spring fixing seat 34, a small spring 35, a limiting column 36 and a small spring fixing seat 37, one end of the large spring 32 is fixed to one end of the steel column 33, the other end of the large spring 32 is fixed to the large spring fixing seat 34, one end of the steel column 33 extends into the interior of the reel barrel 31, the other end of the steel column 33 passes through the large spring fixing seat 34 and is fixed to the right fixed connector 13, and the large spring fixing seat 34 is fixed to the interior of the reel barrel 31;

[0028] One end of the small spring 35 is fixed to one end of the limiting column 36, and the other end of the small spring 35 is fixed to the small spring fixing seat 37. One end of the limiting column 36 extends into the interior of the reel tube 31, and the other end of the limiting column 36 passes through the small spring fixing seat 37 and is fixed to the left fixed connector 12. The left fixed connector 12 and the right fixed connector 13 are both fixed to the frame 1.

[0029] Specifically, when the sliding handle rod 8 drives the sunshade 4 to unfold on the car sunroof, the reel drum 31 rotates, and the large spring fixing seat 34 and the small spring fixing seat 37 also rotate. Since the steel column 33 and the limit column 36 are fixed on the left fixed connecting member 12 and the right fixed connecting member 13, the large spring 32 and the small spring 35 are twisted and deformed, and the elastic force of the spring keeps the sunshade 4 in a taut and flat state front and back; when the sliding handle rod 8 drives the sunshade 4 to roll up on the car sunroof, the elastic force of the large spring 32 and the small spring 35 causes the sunshade 4 to roll up on the reel drum 31, and the elastic force of the spring keeps the sunshade 4 flat front and back, and the sunshade is neatly and smoothly wound on the reel drum 31.

[0030] The outer peripheral surface of the reel 31 is fixedly connected to the end of the sunshade 4, the front end of the sunshade 4 is connected to the sliding handle rod 8, and the two sides of the sunshade 4 are slidably connected to the track 7, and the track 7 is installed on the frame 1 and the two tracks 7 are arranged opposite to each other;

[0031] The two ends of the sliding handle rod 8 are fixedly connected with a left sliding connector 9 and a right sliding connector 10 , and the driving component 2 drives the left sliding connector 9 and the right sliding connector 10 to move along the track 7 .

[0032] Side strips 5 are sewn on both sides of the sunshade 4, and the side strips 5 are slidably connected in the slide grooves of the track 7. Specifically, the side strips 5 are embedded in the grooves corresponding to the track 7, so as to keep the sunshade 4 flat on the left and right.

[0033] The front end of the sunshade curtain 4 is sewn into a cylinder, which is embedded in the groove of the sliding handle rod 8. A steel wire 6 is embedded in the cylinder, and both ends of the steel wire 6 are fixed to the sliding handle rod 8 to facilitate the sliding handle rod 8 to drive the front end of the sunshade curtain 4 to move.

[0034] The driving assembly 2 includes a motor 21, two flexible shafts 22 and a gear 23. The output shaft of the motor 21 is connected to the gear 23. The gear 23 is respectively engaged with the two flexible shafts 22. One end of one flexible shaft 22 is fixedly connected to the left sliding connector 9, and one end of the other flexible shaft 22 is fixedly connected to the right sliding connector 10.

[0035] Specifically, the motor 21 drives the gear 23 to rotate, and the gear 23 drives the two flexible shafts 22 to move in opposite directions, so that the two flexible shafts 22 drive the sliding handle rod 8 to move forward and backward along the track 7. The opening and closing of the sunshade 4 can be controlled by changing the rotation direction of the motor 21 through the controller.

[0036] Specifically, the flexible shaft 22 is outer-coated with a steel pipe.

[0037] Specifically, the frame 1 includes a front fixed beam, a rear fixed beam and a motor fixed beam. The two ends of the front fixed beam are fixed with a left fixed connector 12 and a right fixed connector 13 by rivets, the motor fixed beam is fixed with a drive assembly 2, and the rear fixed beam is fixedly connected to the track 7 by rivets.

[0038] Specifically, the shape of the roof can be designed according to the vehicle model, and the track can be an arc structure or a straight structure.

[0039] The use process of the utility model is as follows:

[0040] First, install the entire device at the position of the car sunroof. When in use, the controller controls the driving component to drive the sunshade 4 to unfold or retract. After the motor 21 is energized, the motor 21 drives the gear 23 to rotate clockwise, and the clockwise rotation of the gear 23 drives the flexible shaft 22 to move forward. The flexible shaft 22 drives the sliding handle rod 8 to move along the track 7, thereby driving the sunshade 4 to close. The motor 21 drives the gear 23 to rotate counterclockwise, and the counterclockwise rotation of the gear 23 drives the flexible shaft 22, and the flexible shaft moves backward, thereby driving the sunshade to open.

[0041] The reel assembly 3 can smoothly roll up and unfold the sunshade 4 on the car sunroof. At the same time, the side strips 5 arranged on the left and right sides of the sunshade 4 are embedded in the grooves corresponding to the track 7, which can also ensure the flatness of the sunshade.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
