[0036] The existing rolling shutter cover has the following problems: (1) The manual push-pull telescopic structure is inconvenient to operate and time-consuming and laborious; (2) The conventional electric telescopic structure drives the rolling shutter to slide on the track through a motor to achieve the opening and closing functions, but it is easily blocked by external dirt, and at the same time, the motor and the controller are prone to failure. And after the motor and the controller fail, or after the vehicle power supply is abnormal, the product will not be able to open and close normally and lose its normal function.

[0037] To solve the above at least one technical problem, the present utility model provides a driving device 200 and a rolling shutter cover 10 with the cover driving device 200.

[0038] With reference to Figure 1 and Figure 2 , the rolling shutter 100 is used to cover the cargo box of the pickup truck. The rolling shutter 100 has the Figure 1 shown open state and the Figure 2 shown storage state. When the rolling shutter 100 is in the open state, the rolling shutter cover 10 can prevent the goods in the cargo box from being blown by the wind and rained on. When the rolling shutter 100 is in the storage state, the user can carry goods in the cargo box. It can be understood that the rolling shutter cover 10 can be used to cover the rear compartment of the pickup truck, and the rolling shutter cover 10 can also be used to cover transport vehicles such as cars and heavy trucks.

[0039] The rolling shutter cover 10 includes a rolling shutter 100 and a driving device 200. The rolling shutter 100 includes a plurality of curtain leaves 110 connected in sequence. The driving device 200 is connected to one end of the rolling shutter 100. The driving device 200 is used to drive the rolling shutter 100 to switch between the open state and the storage state.

[0040] Specifically, with reference to Figure 3 and Figure 4 , the driving device 200 includes a driving motor 210, a transmission member 220, and a control component 230. The driving motor 210 is the power source for driving the rolling shutter 100. The transmission member 220 connects the driving motor 210 and the rolling shutter 100 so that the driving motor 210 can drive the rolling shutter 100. The control component 230 is connected to the driving motor 210. The control component 230 is used to control the rotation shaft of the driving motor 210 to abut against the transmission member 220 or cancel the abutment against the transmission member 220.

[0041] In the present utility model, since the control component 230 can control the rotation shaft of the driving motor 210 to abut or cancel abutting against the transmission member 220, the rolling curtain cover 10 can be switched between the electric mode and the manual mode. In the electric mode, the rotation shaft of the driving motor 210 abuts against the transmission member 220, and the driving motor 210 can drive the rolling curtain 100 to move. In the manual mode, the rotation shaft of the driving motor 210 cancels abutting against the rotating member, and the user can move the rolling curtain 100 by hand to open or store the rolling curtain 100.

[0042] The control component 230 includes a control member 231 and a limiting member 232. The control member 231 is connected to the driving motor 210 and can drive the driving motor 210 to move along its axial direction. The "axial direction" refers to the axial direction of the rotation shaft of the driving motor 210. The limiting member 232 abuts against the side of the transmission member 220 away from the driving motor 210, and the limiting member 232 can prevent the transmission member 220 from completely disengaging from the driving motor 210.

[0043] In this embodiment, the limiting member 232 is a bolt. It can be understood that in other embodiments, the limiting member 232 can also be set to its limiting structure, such as a buckle.

[0044] Specifically, with reference to Figure 4 and Figure 6 , the control member 231 is a rotating ring 2311. When the rotating ring 2311 is rotated forward, the rotating ring 2311 drives the driving motor 210 to move along its axial direction and abut against the transmission member 220. When the rotating ring 2311 is rotated backward, the rotating ring 2311 drives the driving motor 210 to move axially in the reverse direction and cancel abutting against the transmission member 220. In this way, the rotating ring 2311 can realize the switching of the driving device 200 between the electric mode and the manual mode. In this embodiment, the rotating ring 2311 is provided with a protrusion 2312 for manual operation, which is convenient for the user to operate. In this way, when rotating the rotating ring 2311, a certain external force needs to be applied in a specific direction, reducing the risk of accidental touch.

[0045] In this embodiment, Figure 4 shows that the transmission member 220 includes a coupling 221 and a reel 222. The inside of the reel 222 is a hollow structure. The rotation shaft of the driving motor 210 movably passes through the inner cavity of the reel 222. The inner wall of the coupling 221 is sleeved on the rotation shaft of the driving motor 210, and the outer wall of the coupling 221 is sleeved on the inner wall of the reel 222. The reel 222 is connected to the curtain leaf 110 on one side of the rolling curtain 100.

[0046] The coupling 221 is provided to reduce the friction resistance between the rotating shaft of the driving motor 210 and the reel 222. When the coupling 221 is excessively worn, the coupling 221 can be directly replaced to reduce the maintenance cost. In addition, in the storage state, the curtain blades 110 on the rolling curtain 100 are wound around the reel 222 in a rolled-up manner to reduce the space occupied by the rolling curtain 100.

[0047] Specifically, in conjunction with reference Figure 4 and Figure 5 A first tooth portion 2211 is provided on the inner wall of the coupling 221, and a second tooth portion 211 is provided on the surface of the rotating shaft of the driving motor 210 close to the coupling 221. The second tooth portion 211 matches the first tooth portion 2211. The transmission between the driving motor 210 and the coupling 221 can be realized through the cooperation between the first tooth portion 2211 and the second tooth portion 211, thereby realizing the driving of the roller blind 100 by the driving motor 210.

[0048] Furthermore, the first tooth portion 2211 and the second tooth portion 211 are both V-shaped teeth. Since the drive motor 210 has to abut or cancel the abutment with the coupling 221 when switching between the electric mode and the manual mode, the V-shaped teeth can facilitate the alignment between the first tooth portion 2211 and the second tooth portion 211, and at the same time, the resistance of the first tooth portion 2211 to disengage from the second tooth portion 211 is smaller, and the disengagement is smoother.

[0049] Figure 4 It is shown that the driving device 200 also includes a transmission bracket, which is connected to the reel 222. The roller blind 100 is correspondingly provided with a transmission shaft 120. The rotating bracket is connected to the transmission shaft 120 so that the curtain blades 110 of the roller blind 100 can be wound and stored on the reel 222 in a rolled-up manner. At the same time, the roller blind 100 is opened more smoothly.

[0050] Specifically, there are two transmission brackets and two rotating shafts, and the two transmission brackets are respectively located on opposite sides of the reel 222, and the position of the transmission shaft 120 matches the position of the transmission bracket. Of course, the manufacturer can also adjust the number of transmission brackets and transmission shafts 120 as needed, and the utility model does not limit this.

[0051] In this embodiment, the driving motor 210 is a rod-type motor, and the rotating shaft of the rod-type motor is passed through the cavity inside the reel 222. One axial end of the rod-type motor is installed on the rolling shutter cover 10, and the other end is connected to the coupling 221, so that both ends of the driving motor 210 are limited. When the rod-type motor rotates, the reel 222 supports and fixes the rod-type motor. The rod-type motor will not produce large shaking and noise, and the operation of the rod-type motor is more stable.

[0052] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains may make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the scope defined by the spirit of the present utility model.
