It should be noted that: like reference numerals refer to like items in the following figures, and thus, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

As shown in fig. 1 to 3, the motorized canopy 100 includes a sunshade assembly 20 and a support assembly 30 below the sunshade assembly 20. The technical scheme mainly explains the operation principle of the sunshade component 20 in detail as follows:

the sunshade assembly 20 includes a front beam pulling mechanism therein, and specifically, the front beam pulling mechanism includes a front beam 21 coupled to a front side of the curtain f, two side rails 22 for sliding the front beam 21, and two elastic pulling assemblies 50.

The two guide rails 22 on the sunshade component 20 are parallel to each other, and the front beam 21 is a movable front beam; the sunshade assembly 20 further comprises a fixed back beam 23 and a sunshade component 24, the sunshade component 24 is a curtain f, the curtain f is connected between the fixed back beam 23 and the front beam 21, the fixed back beam 23 is fixedly connected to the rear ends of the two guide rails 22, the front beam 21 is arranged at the front ends of the two guide rails 22, a winding assembly 40 capable of winding or releasing the curtain f is arranged in the fixed back beam 23, an elastic traction assembly 50 is arranged between the front beam 21 and the guide rails 22, the winding assembly 40 winds and pulls the curtain f, and the front beam 21 moves along the guide rails 22 to the fixed back beam 23 along with the curtain f, at the moment, the elastic traction assembly 50 stores force; winding assembly 40 reversely releases curtain f, which moves along guide rail 22 away from fixed back beam 23 following front beam 21 under the traction force of elastic traction assembly 50. The fixed back beam 23 is mounted on the wall Q through the base 10.

The sunshade component 20 comprises a guide rail 22, a front beam 21 and a fixed rear beam 23, a winding component 40 capable of winding and releasing a curtain f is arranged in the fixed rear beam 23, and an elastic traction component 50 is arranged between the front beam 21 and the guide rail 22; when the winding assembly 40 winds and pulls the curtain f on the sunshade assembly 20 to move towards the direction of the fixed back beam 23, the elastic traction assembly 50 stores force, and when the winding assembly 40 removes the backward pulling force on the curtain f, the curtain f follows the front beam 21 to move along the guide rail 22 in the direction away from the fixed back beam 23 under the traction force of the elastic traction assembly 50. Thereby realizing that the curtain f moves backwards under the action of the pulling force and the curtain f automatically moves back under the action of the elastic traction component 50.

As shown in fig. 4 to 6, the elastic traction assembly 50 includes a force storable elastic member 52 and a traction member 51, one end of the elastic member 52 is connected to one end of the traction member 51; the other end of the elastic component 52 is fixed on the guide rail 22, and the other end of the traction component 51 is fixed on the front beam 21; or the other end of the elastic member 52 is fixed to the front beam 21 and the other end of the pulling member 51 is fixed to the guide rail 22. The above technical means are to illustrate that the elastic traction assembly 50 can be arranged in the inner cavity of the front beam 21 or the inner cavity of the guide rail 22 according to actual needs. The present embodiment will be explained in detail mainly by taking the elastic member 52 disposed in the guide rail 22 as an example.

Specifically, in the front beam traction mechanism, the elastic member 52 of the elastic traction unit 50 is mounted in the front beam 21, the end of the elastic member 52 is fixed to the front beam 21, one end of the traction member 51 is connected to the telescopic end of the elastic member 52, the other end of the traction member 51 is fixed to the guide rail 22, and the front beam 21 is driven to return to the front end of the guide rail 22 by a pulling force generated after the elastic member 52 is extended. Of course, the elastic member 52 may be disposed in the front beam 21.

Preferably, the elastic member 52 in the present embodiment is a spring or a gas spring 52 d. The traction member 51 is a wire rope or a braided rope.

It should be elaborated on that the gas spring 52d includes a fixed pipe d1 and an expansion link d2, the rear end of the fixed pipe d1 and the front end of the expansion link d2 are respectively provided with 2-3 pulleys 53, the traction member 51 sequentially passes around each pulley 53 and is connected with the front end of the guide rail 23, so that the length of the traction member 51 in the front beam 21 can be changed along with the length change of the gas spring 52 d. The number of the pulleys 53 may be arranged according to the length of the traction member 51, and the pulleys 53 mainly function to achieve winding of the traction member 51 having a certain length to minimize a space for accommodating the traction member 51.

A diverting pulley 54 is provided at an end of the front beam 21 that contacts the guide rail 22, and the traction member 51 extending from the gas spring 52d is fixed to the front end of the guide rail 22 after passing around the diverting pulley 54. The diverting pulley 54 is mounted so that the originally transversely running traction element 51 can be converted into a longitudinally running traction element.

Preferably, two resilient traction assemblies 50 are preferably installed in this embodiment. The two elastic members 52 are distributed in the left and right sections in the cavity of the front beam 21 and are arranged in a staggered manner, and the traction members 51 corresponding to each elastic member are respectively connected to the front ends of the guide rails 22 on the corresponding side.

Specifically, when the vehicle is mounted, the two gas springs 52d in the front beam 21 are disposed in a staggered manner in the cavity in the front beam 21, and the other ends of the traction members 51 corresponding to the gas springs 52d are fixed to the front ends of the respective corresponding side rails 22.

In actual use, the front beam 21 moves backward along with the curtain f until the elastic member 52 extends, and after the pulling force of the curtain f is removed, the front beam 21 is driven to return to the front end of the guide rail 22 by the pulling force generated after the elastic member f extends.

The winding assembly 40 includes a winding drum 42 which is provided in the fixed back beam 23 and can wind the curtain f and a motor 41 which drives the winding drum 42, and an opening 02 for the curtain f to enter and exit is provided in the front side of the fixed back beam 23.

In operation, the motor 41 is activated to drive the winding drum 42 to apply a pulling force to the curtain f and wind the curtain f, and at this time, the curtain f moves backward along the guide rail 22 to drive the L1 section of the traction member 50 fixed at one end on the front beam 21 to be stretched, and the telescopic rod d2 on the gas spring 52d moves into the fixed tube d1, that is, the corresponding L2 section is compressed to store the force of the gas spring 52 d.

When the motor 41 is turned off, the winding drum 42 stops applying a pulling force to the curtain f, at this time, the telescopic rod d2 on the air spring 52d moves outwards under the action of a rebound force, so that the corresponding L2 section is stretched, one end of the telescopic rod d2 is connected with the traction component 52, so that the traction component 51 is pulled back, the other end of the traction component 52 is fixed on the front beam 21, and then the traction component 52 drives the front beam 21 to move outwards, so that the distance of the L1 is gradually reduced. The combination of the elastic member 52 and the winding unit 40 installed in the fixed rear frame 23 allows the curtain f to be unwound and wound and the front and rear frames 21 to be horizontally moved.
