[0017] The beneficial effects of the present invention are embodied in:

[0018] 1. The car cover body of the present invention is folded and rolled up on the central axis, and the folded end of the car cover body is always connected to the central axis, so that after the car cover body is unfolded, the car cover body can be rolled up on the central axis by rotating the central axis, and the two ends of the car cover body extend from the opening to form a first car cover and a second car cover facing back to back, and the first car cover and the second car cover respectively cover the front and rear of the car body. In the process of extending and rolling up, the car cover body allows the first car cover and the second car cover to complete the unfolding and rolling up at the same time, reducing the time for extending, unfolding and rolling up, and improving the efficiency of covering and rolling up; the first car cover is provided with a toothed belt along the length direction, and the toothed belt is connected to the first car cover through a connecting cloth, so that the toothed belt and the connecting cloth can be connected to the first car cover. The cloth remains intact, and a gap is set between the toothed belt and the connecting cloth. The gear of the driving unit is located in the gap and meshes with the toothed belt. The rotation of the gear drives the toothed belt to move relatively, and then drives the first car cover to move toward the front of the vehicle body. At this time, the middle axis rotates, and the second car cover gradually separates from the middle axis and moves toward the rear of the vehicle body, so that the car cover body is extended from the collecting tube to cover the vehicle body; a lifting and movable pressure wheel is set at the lower end of the toothed belt, and the pressure wheel squeezes the toothed belt upward to keep the toothed belt and the gear meshing at all times, avoiding slipping caused by excessive distance between the toothed belt and the gear, which causes the car cover body to be unable to unfold smoothly, thereby ensuring the stability of the car cover body during use and reducing failures.

[0019] 2. The outer part of the connecting cloth forms a T shape, and the narrow upper end of the connecting cloth is connected to the lower end of the first car cover, and the lower end of the connecting cloth is parallel to the first car cover. The length of the connecting cloth is the same as the length of the first car cover, and two toothed belts are respectively arranged on the left and right sides of the T-shaped connecting cloth, and the toothed belts and the connecting cloth are connected to each other by sewing or bonding. By setting two toothed belts, the toothed belts on the left and right sides of the connecting cloth are driven at the same time, so that the force of the connecting cloth is transmitted to the first car cover more evenly, and it is avoided that the connecting cloth is subjected to the force of the toothed belt transmission on one side, causing the connecting cloth to deviate toward the direction of the single-sided toothed belt, thereby affecting the first car cover to deviate to one side during the extension process. The two reduction motors of the two driving units are symmetrically arranged on the left and right sides of the connecting cloth, and the toothed belt is cleverly driven to move by the rotation of the gears, so that the toothed belt, the connecting cloth and the first car cover move as a whole.

[0020] 3. The fixing frame is formed by bending the upper and lower ends of a plate toward the direction close to the collecting cylinder. The reduction motor is fixed to the upper end of the fixing frame through the motor bracket, and the position of the gear is fixed. The first car garment, the toothed belt and the connecting cloth are always located at the upper end of the fixing frame during the winding process. The pressure wheel arranged on the fixing frame can penetrate the upper end of the fixing frame and contact with the toothed belt. The pressure wheel squeezes the toothed belt upward to ensure that the toothed belt and the gear are in meshing state, thereby ensuring that the gear and the toothed belt are always meshed and will not slip when the first car garment is unfolded. The pressure wheel rotation sleeve is arranged on the pressure wheel shaft. The pressure wheel can rotate to ensure that the pressure wheel and the toothed belt are in close contact. During the movement of the toothed belt, there is rolling friction between the toothed belt and the pressure wheel, which ensures that the friction force is reduced while the pressure is tightened, reduces the frictional heat, and increases the service life of the toothed belt. The pressure wheel can be lifted and moved. When it is necessary to wind up the car garment body, the pressure wheel moves downward, the gear is disengaged from the toothed belt, and the central axis rotates to reduce the friction force of the toothed belt when the car garment body is wound up, making it easier to wind up the car garment.

[0021] 4. The lifting and lowering movement of the pressure wheel is realized by the jacking unit, and the push-pull electromagnet can realize the forward and backward movement of the sliding frame. The sliding frame is fixedly connected to the wedge block, and the wedge block moves with the sliding frame. The wedge block is provided with an inclined surface, and the two ends of the pressure wheel shaft are located on the inclined surfaces of the two wedge blocks. The wedge block moves forward and backward to realize the height change of the pressure wheel shaft in the vertical direction, thereby realizing the lifting and lowering movement of the pressure wheel; the sliding groove opened by the motor bracket has a limiting effect on the pressure wheel shaft, and at the same time, when the pressure wheel shaft is at the lowest end, it also plays a supporting role; a limiting block is arranged at the rear end of the sliding shaft to protect the wedge block and prevent the wedge block from detaching from the sliding shaft.

[0022] 5. Through the elastic support strips and the elastic mesh frame, when the first garment and the second garment are unfolded, the first garment and the second garment are respectively supported by the elastic support strips and the elastic mesh frame and move forward smoothly without being accumulated at the opening of the collecting barrel, and the elastic support strips and the elastic mesh frame are respectively wound around the central axis following the first garment and the second garment.

[0023] 6. A circle of tensioning rope is arranged on the edge of the car cover body, and a contraction opening is arranged when the tensioning rope is disconnected, and a locking shaft and a locking tongue are arranged at both ends of the contraction opening. The locking shaft and the locking tongue are remote control locks, and the tensioning rope is an electric wire, which is electrically connected to the controller, and the electric wire is provided with a destruction alarm device; when the car cover is completely covered on the car body, the locking shaft and the locking tongue are locked by manual operation, so that the locking shaft and the locking tongue move toward each other, and the locking tongue enters the locking shaft to complete the locking, so that the edge of the car cover body is contracted; when the car cover body needs to be rolled up, the remote control lock is turned on, the locking tongue moves out of the locking shaft, and the middle shaft rotates to collect the car cover body.

[0024] 7. There are multiple windproof openings on the car cover body to prevent the inside of the car cover from being damaged by wind when the car cover body is fully covered. A cloth cover is added to the windproof opening, which covers the windproof opening and is connected to the cover cloth at one end to form an openable and closable cover that is tightly attached to the cover cloth to prevent wind, rain, dust, etc. from entering from the outside.

[0025] 8. End caps are arranged at both ends of the collecting tube, and a lining plate is arranged inside the collecting tube. The lining plate is located between the collecting tube and the end caps. The end caps are recessed outward to form a receiving cavity. A driving motor, a controller and a battery are arranged inside the end cap close to the handle, and a conductive slip ring is arranged inside the end cap away from the handle. The central axis is hollow, and a process hole for the wire to pass through is opened in the middle.

[0026] The battery is connected to a wire, which extends from the side of the end cover and penetrates the outer wall of the collecting tube, and is simultaneously connected to the push-pull electromagnet, the conductive slip ring and the reduction motor through the outer wall of the collecting tube. The tensioning rope is an electric wire, which is electrically connected to the lock shaft and the lock tongue. The electric wire passes through the middle part of the first car cover and then passes through the central shaft and is electrically connected to the conductive slip ring, so that the central shaft remains energized during rotation; the rotation of the central shaft, the push-pull electromagnet and the power supply of the reduction motor are all provided by the battery in the end cover.

[0027] 9. When the protective cover is needed, place the collection tube on the upper end of the car body. After use, roll the car cover body into the collection tube, take the collection tube off the upper end of the car body and place it in the trunk of the car body. The upper end of the collection tube is also provided with an angle shaft to make the first car cover change direction smoothly; through the suction cup, the present application is closely fitted with the upper end of the car body during use to maintain its integrity with the car body; a handle is provided on one side of the end cover, and a universal wheel is provided on the other side of the end cover, so as to facilitate the placement of the protective cover of the present application on the upper end of the car body and the removal of the protective cover from the upper end of the car body, and slide with the top of the car body through the universal wheel to avoid direct friction and damage to the car body.
