The upper part of the inner frame 6 is connected to the inner side of the upper cover 7, and an X-shaped stretching mechanism 7 is arranged at the lower part. The X-shaped stretching mechanism 7 is connected to the four corners of the umbrella cloth 8. At the same time, an umbrella cloth winding mechanism 9 is arranged at the center of the X-shaped stretching mechanism 7. A storage battery connected to the inner frame lifting mechanism 5 and the X-shaped stretching mechanism 7 is arranged in the sunshade installation cavity, and a solar charging panel 10 connected to the storage battery is arranged on the top of the upper cover.

[0048] Before the X-type extension mechanism works, the inner frame lifting mechanism drives the inner frame, the X-type extension mechanism, the umbrella surface winding mechanism, and the upper cover on its upper part to rise, providing a working space for the X-type extension mechanism; the inner frame lifting mechanism 5 includes a lifting drive rod 501 and a drive motor 502 that drives it to rotate. Both ends of the lifting drive rod 501 are respectively connected to the lifting transmission rod 504 through a cross steering gearbox 503. Both ends of the lifting transmission rod 504 are respectively provided with a Hocken linear mechanism 12 connected to the bottom of the inner frame 6. A boosting spring 13 is arranged between the moving end of the Hocken linear mechanism 12 and the bottom bar 10; a limit switch bracket 507 is arranged at the connection between the cross steering gearbox 503 and the lifting transmission rod. Limit switch brackets 507 are respectively arranged on both sides of the lifting transmission rod 504 with a rising limit switch 505 and a retracting limit switch 506.

[0049] The Hocken linear mechanism 12 includes a drive block 1201 arranged at the end of the lifting drive rod 12. One end of the drive block 1201 is hinged with a drive arm 1202. The other end of the drive arm 1202 is hinged with a bracket 1203 connected to the inner frame 6. The middle of the drive arm 1202 is hinged with a connecting arm 1204. The other end of the connecting arm 1204 is externally hinged with the cross steering gearbox 503; the drive arm 1202 includes a downwardly protruding arc arm 1202a hinged with the drive block 1201 and a straight arm 1202b hinged with the bracket 1203. The connecting arm 1204 is hinged at the connection between the arc arm 1202a and the straight arm 1202b; the bracket 1203 includes an L-shaped bearing frame 1203a. One end of the L-shaped bearing frame 1203a is hinged with the drive arm 1202 through a hinge block 1203b. The inner frame 6 is connected to the L-shaped bearing frame 1203a; the L-shaped bearing frame 1203a is connected to one end of the boosting spring 13. The other end of the boosting spring 13 is connected to the bottom bar 10; the boosting spring 13 includes a spring coil part 1301. One end of the spring coil part 1301 is rotatably connected to the L-shaped bearing frame 1203a through a connecting rod one 1302, and the other end is rotatably connected to the bottom bar 10 through a connecting rod two 1303. A spring socket corresponding to the connecting rod two 1303 is arranged on the bottom bar 10.

[0050] When the inner frame lifting mechanism works, the drive motor acts. The drive motor gearbox distributes the horizontally transmitted power through its internal worm and gear reduction to the cross steering gearboxes on both sides. The cross steering gearbox changes the transmission direction again through the internal worm and gear reduction inside it, driving the lifting transmission rod. At the same time, power is distributed to the Hocken linear mechanisms at the rear two ends through the lifting transmission rod, forming synchronous lifting at four points. The characteristic of the Hocken linear mechanism is that it evolves from rotational motion to linear motion, and at the same time, the motion speed is stable and controllable. Springs are set at all four points to assist the lifting action to save effort. The work done by the rising and falling actions is balanced. The rising is done by the spring and the motor at the same time, and the falling is done by the motor and the weight of the inner frame itself at the same time.

[0051] The inner frame lifting mechanism raises the inner frame inside the parasol, and then the X-shaped extension mechanism extends to pull out the umbrella cloth to form the parasol.

[0052] The X-shaped extension mechanism 7 includes a first telescopic structure 701 and a second telescopic structure 702 arranged in parallel, and a third telescopic structure 703 and a fourth telescopic structure 704 arranged in parallel. The first telescopic structure 701, the second telescopic structure 702 and the third telescopic structure 703 and the fourth telescopic structure 704 are staggered in an X shape. An upper central gear 705 is arranged in the middle of the first telescopic structure 701 and the second telescopic structure 702, and a lower central gear 706 is arranged in the middle of the third telescopic structure 703 and the fourth telescopic structure 704. The upper central gear 705 and the lower central gear 706 are coaxial and arranged in opposite directions. A rack 707 meshing with the upper central gear 705 and the lower central gear 706 is arranged on the side walls of the first telescopic structure 701, the second telescopic structure 702, the third telescopic structure 703 and the fourth telescopic structure 704, and the upper central gear 705 and the lower central gear 706 are transmission-connected to the umbrella cloth winding mechanism 9; the second telescopic structure 702, the third telescopic structure 703 and the fourth telescopic structure 704 are all connected to the first telescopic structure 7 01, the first telescopic structure 701 includes a telescopic tube 701a provided with a rack 707, a fiber rod 701b is provided in the telescopic tube 701a, the front end of the fiber rod 701b extends out of the telescopic tube along the moving direction of the telescopic tube, a movable pulley 1 701c is provided at one end of the telescopic tube 701a near the front end of the fiber rod 701b, and a movable pulley 2 701d is provided at the other end, a fixed pulley 1 701e is provided on the inner frame of one side of the telescopic tube 701a, and one end of the telescopic tube 701a provided with the movable pulley 2 701d is provided with an outer A fixed pulley 2 701f is arranged on the inner frame 6, a movable end 701g is arranged on the outer wall of one end of the telescopic tube 701a where the movable pulley 2 701d is arranged, and a pull rope 1 701h and a pull rope 2 701j are connected to the movable end 701g. The pull rope 1 701h passes through the fixed pulley 2 701f and the movable pulley 1 701c in sequence from the mobile end and is connected to the rear end of the fiber rod 701b. The pull rope 2 701j passes through the fixed pulley 1 701e and the movable pulley 2 701d in sequence from the mobile end 701g and is connected to the rear end of the fiber rod 701b.

[0053] When the X-shaped extension mechanism extends outward, the upper center gear and the lower center gear drive the four telescopic structures to extend outward, and the movable pulley 701c at the front end of the telescopic tube moves forward with the telescopic structure, and the fixed pulley 701f outside the telescopic tube does not move. The distance between the movable pulley 701c and the fixed pulley 701f is enlarged, and the other end of the pull rope 701b is fixed on the fiber rod, forming a telescopic tube extension with the fiber rod extension and a relationship of twice the distance.

[0054] When the X-shaped extension mechanism retracts inward, when the upper central gear and the lower central gear drive the four telescopic structures to retract inward, the movable pulley II 701d at the rear end of the telescopic tube moves backward, and the fixed pulley I 701e outside the telescopic tube remains in place without changing its position. The distance between the movable pulley II 701d and the fixed pulley I 701e increases. The other end of the pulling rope II 701j is fixed to the fiber rod, causing the telescopic tube to move backward, driving the fiber rod to retract, and presenting a two-fold distance relationship. Due to the extension pulley set and the retraction pulley set having opposite actions and opposite functions, the fixed points of the steel wire ropes are the same, the movement multiples are the same, and they are used as a complete closed-loop movement, and one steel wire rope is fixed at three points to present the simultaneous use of two pulley sets.

[0055] Since each telescopic structure in the X-shaped extension mechanism is connected to a corner of the umbrella cloth, when the X-shaped extension mechanism extends outward, the umbrella cloth is pulled and stretched outward. When the umbrella cloth 8 is in the stretched state, ventilation openings 11 are provided at the top and middle of its four sides.

[0056] In this embodiment, the external shape of the sunshade is designed to be streamlined, which can reduce wind resistance and energy consumption. The sunshade cloth is extended by four telescopic structures. The telescopic structures are made of fiber tubes, and after reaching the size of the umbrella cloth, they continue to extend a certain length. The sunshade cloth will be taut and present a downward-bent shape, achieving a tight and plump sunshade shape.

[0057] Regarding the cooling effect: After the umbrella cloth is opened, there is a certain gap between the umbrella cloth and the vehicle body, and the sunlight is blocked so that it does not directly shine on the vehicle body, achieving a cooling effect. After the sunlight heats the umbrella cloth, the hot air will rise, travel upward through the gap between the vehicle body and the umbrella cloth inside the sunshade, and disperse from the ventilation openings at the top of the four sides of the umbrella cloth, forming a heat convection effect. In this way, after the sunlight heats the umbrella cloth, the sunshade cloth will not trap the heat to achieve a cooling effect.

[0058] Regarding the wind resistance effect: When the strong wind blows onto the umbrella cloth, it enters from one ventilation opening of the umbrella cloth and blows out from the ventilation openings on the other three sides, achieving the effect of reducing wind resistance. The four fiber rods supporting the opened sunshade have resilience, supporting the umbrella cloth to achieve the effect of not being damaged by strong winds.

[0059] When the umbrella cloth needs to be wound up, it is wound up by the umbrella cloth winding mechanism. The umbrella cloth winding mechanism 9 includes an upper limit plate 901 and a lower limit plate 902 arranged at intervals, a cloth winding disc 903 arranged between the upper limit plate 901 and the lower limit plate 902, and a gear box 904 for driving the cloth winding disc 903 to rotate. The middle part of the umbrella cloth 8 is connected to the outside of the cloth winding disc 901. The gear box 904 includes a winding motor 904a. The output shaft of the winding motor 904a is connected to an output gear 904b. The output gear 904b is externally engaged with a cloth winding disc output gear 904c and a central gear disc 904d. The inner side of the central gear disc 904d is engaged with a central sun gear 904f through several planetary gears 904e. The central gear disc 904f is connected to the lower central gear 706 through a shaft, and the central sun gear 904f is directly connected to the upper central gear 705.

[0060] When the umbrella cloth winding mechanism works, the output gear of the winding motor rotates to drive the central gear disc and the cloth winding disc output gear. The central gear disc rotates to drive the planetary gears. The number of teeth of the planetary gears is halved to drive the central sun gear, forming a synchronous rotation in opposite directions of the central sun gear and the central gear disc. Then, the central gear disc fixes the lower layer output gear through the central transmission main shaft, and the central sun gear fixes the upper layer output gear, presenting a synchronous rotation in opposite directions of the upper and lower layer output gears. The cloth winding disc output wheel on the upper side of the central gear box drives the cloth winding disc to stir the sunshade umbrella cloth into the upper limit plate and the lower limit plate.

[0061] A bottom bar 10 is connected between the sunshade umbrella feet 4 and supported at the bottom of the bottom plate 1. The sunshade foot 4 includes a foot support member 401. One end of the foot support member 401 is provided with an outer gripper 402 downward. An inner gripper 403 is oppositely arranged on one side of the outer gripper 402. The inner gripper 403 is arranged in the foot support member 401 through an inner gripper mounting plate 404. Among them, the foot support member 401 and the outer gripper 402 are integrally formed, the inner gripper 403 and the inner gripper mounting plate 40 are integrally formed. A first locking bolt 405 is arranged between the top of the inner gripper 403 and the outer gripper 402, and a second locking bolt for connecting to the bottom bar 10 is arranged at the top of the foot support member 401.

[0062] When installing the sunshade umbrella feet, place them on the car luggage rack, tighten the first locking bolt to clamp the luggage rack to fix the feet, and tighten the second locking bolt to fix the bottom bar. The two bottom bars and four feet fix the car luggage rack to firmly fix the sunshade umbrella and the car luggage rack. The car luggage rack can be separated or integrated, and two types of feet can be set for matching installation as shown in the appendix Figure 20 、 Figure 21 to set two types of feet for matching installation.

[0063] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. In general, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
