[0042] Typical embodiments embodying the features and advantages of the present utility model will be described in detail in the following description. It should be understood that the present utility model can have various changes in different embodiments, all of which do not depart from the scope of the present utility model, and the descriptions and illustrations therein are essentially for illustrative purposes and not for limiting the present utility model.

[0043] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present utility model, "a plurality of" means two or more unless otherwise specifically defined. In addition, " / " means "or", for example, A / B can mean A or B; "and / or" herein is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone.

[0044] Unless otherwise clearly specified and defined, the terms "set", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components.

[0045] Existing rolling shutters have the following problems: (1) Manually rolling the plastic covering cloth, using the carriage frame structure, processing the edge locking on the cloth to form a structure for manual rolling and locking the carriage covering with the frame structure, but this plastic is easily damaged and aged; (2) Using a hard board structure to achieve folding coverage through a hinge structure, it is prone to leakage and inconvenient for adults to operate; (3) Manually pushing and pulling a telescopic structure, which is inconvenient to operate and time-consuming and laborious.

[0046] To solve at least one of the above technical problems, the present utility model proposes a rolling shutter cover.

[0047] With reference to Figure 1 , Figure 2 and Figure 3 , the rolling shutter cover 10 is used to shield the cargo box of a pickup truck. The rolling shutter 100 has the open state shown in Figure 1 and the storage state shown in Figure 2 . 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, users can carry goods in the cargo box. It can be understood that in addition to being able to be used to shield the rear cargo box of a pickup truck, the rolling shutter 100 can also be used to shield transport vehicles such as cars and heavy-duty trucks.

[0048] The rolling shutter cover 10 includes a rolling shutter 100, a slide rail 200 and a driving device 300. The rolling shutter 100 is connected to the slide rail 200 and can move on the slide rail 200. The rolling shutter 100 includes a plurality of curtain leaves 110 connected in sequence. The driving device 300 is connected to one end of the rolling shutter 100, and the driving device 300 can drive the rolling shutter 100 to move on the slide rail 200 so that the rolling shutter 100 can be switched between the open state and the storage state.

[0049] It should be noted that the "length direction" mentioned throughout the present utility model is as shown in Figure 1 . The "length direction" refers to the direction perpendicular to the moving direction of the rolling shutter 100, and the "length direction" has nothing to do with the specific numerical value.

[0050] In the present utility model, since the rolling shutter cover 10 is provided with a slide rail 200, the slide rail 200 can make the movement of the rolling shutter 100 smoother. The slide rail 200 can also play a role in shielding the edge of the rolling shutter 100 to prevent rainwater and the like from entering the cargo box. At the same time, the driving device 300 can drive the rolling shutter 100 to move, saving time and effort.

[0051] Specifically, with reference to Figure 4 and Figure 5 , the rolling shutter cover 10 further includes a reel 400. The driving device 300 is a motor 310. The rotating shaft of the motor 310 is connected to the reel 400, and the reel 400 is sleeved on the outer surface of the rotating shaft of the motor 310. In this way, in addition to being able to play a role in transmission, the reel 400 can also support and protect the motor 310.

[0052] Furthermore, Figure 5 shows that the rolling shutter cover 10 further includes a transmission bracket 410. Figure 4It is shown that a transmission shaft 120 is provided on the rolling curtain 100, and the transmission bracket 410 is connected to the transmission shaft 120. The number of both the transmission bracket 410 and the transmission shaft 120 is two. The two transmission brackets 410 are respectively located on both sides of the axial direction of the reel 400, and the position of the transmission shaft 120 is adapted to the position of the transmission bracket 410. Of course, the manufacturer can also adjust the number of the transmission bracket 410 and the transmission shaft 120 according to needs, and the present utility model does not limit this.

[0053] In this embodiment, the rolling curtain cover 10 further includes a coupling 420. The inner wall of the coupling 420 is sleeved on the rotating shaft of the motor 310, and the outer wall of the coupling 420 is sleeved on the inner wall of the reel 400. In this way, the frictional resistance between the rotating shaft of the motor 310 and the reel 400 can be reduced. When the coupling 420 is worn out too much, the coupling 420 can be directly replaced, reducing the maintenance cost.

[0054] Specifically, a first tooth portion 421 is provided on the inner wall of the coupling 420, and a second tooth portion 312 adapted to the first tooth portion 421 is provided on the rotating shaft of the motor 310. The cooperation of the first tooth portion 421 and the second tooth portion 312 can realize the transmission between the coupling 420 and the rotating shaft of the motor 310.

[0055] During the use of the rolling curtain cover 10, it is easily blocked by external dirt, and at the same time, the motor and the controller may malfunction. After the motor and the controller malfunction, or after the vehicle power supply is abnormal, the product will not be able to open and close normally and lose its normal function.

[0056] To solve the above technical problems, the rolling curtain cover 10 further includes a control component 500. The control component 500 is connected to the coupling 420, and the control component 500 can drive the coupling 420 to be sleeved on the motor 310 or separated from the motor 310. In this way, the control component 500 can realize the switching of the electric mode of the rolling curtain cover 10. Exemplarily, in the electric mode, the motor 310 is connected to the reel 400 through the coupling 420, and the reel 400 is connected to the rolling curtain 100. The motor 310 rotates forward or backward to control the rolling curtain 100 to open or be retracted. When it is necessary to adjust the electric mode to the manual mode, the user only needs to operate the control component 500 to drive the coupling 420 to separate from the rotating shaft of the motor 310. At this time, the user can move the rolling curtain 100 by hand to open or retract the rolling curtain 100.

[0057] Specifically, the control component 500 includes a limiting member 510 and a control member 520. The limiting member 510 abuts against one side of the coupling 420 to limit the stroke of the coupling 420 in the length direction of the reel 400. The control member 520 is connected to the motor 310 to drive the motor 310 to move in its axial direction.

[0058] In this embodiment, the control member 520 is a rotating ring 521. The rotating ring 521 is provided with a convex structure for manual operation. When the rotating ring 521 is rotated by hand, since the rotating ring 521 is connected to the motor 310, the rotating ring 521 drives the motor 310 to rotate and the motor 310 moves along its axial direction, so that the engagement between the first tooth portion 421 and the second tooth portion 312 is cancelled, and the rolling shutter cover 10 is switched from the electric mode to the manual mode. Then, when the rotating ring 521 is rotated in the reverse direction, the motor 310 moves axially in the reverse direction, and the rolling shutter cover 10 is switched from the manual mode to the electric mode.

[0059] It can be understood that rotating the rotating ring 521 requires applying an external force in a specific direction, which reduces the possibility of accidental touch. Of course, in other embodiments, the control assembly 500 can also be set to other existing switch structures. For example, the coupling 420 can be controlled by additionally setting a driving motor and a button connected to the coupling 420 to switch between the electric mode and the manual mode.

[0060] Furthermore, both the first tooth portion 421 and the second tooth portion 312 are V-shaped teeth. Since the coupling 420 needs to be sleeved on or disengaged from the motor 310, the V-shaped teeth can facilitate the alignment between the first tooth portion 421 and the second tooth portion 312, and at the same time, it is smoother for the first tooth portion 421 to disengage from the second tooth portion 312.

[0061] The rolling shutter cover 10 further includes a box body 600. The box body 600 is used to accommodate the motor 310 and the rolling shutter 100. Both ends of the shaft of the reel 400 are respectively installed in the mounting holes 610 on both sides in the length direction of the box body 600. In this way, the reel 400 can be made more stable, avoiding deformation caused by only fixing one side of the reel 400. At the same time, the support of the reel 400 for the motor 310 is more stable, preventing the rotation shaft of the motor 310 from shaking during rotation.

[0062] Specifically, the rolling shutter cover 10 further includes an adapter ring 620. The inner wall of the adapter ring 620 is sleeved on the outer wall of the reel 400, and the outer wall of the adapter ring 620 is sleeved on the inner wall of the mounting hole 610. In this way, the frictional resistance between the reel 400 and the mounting hole 610 can be reduced. When the adapter ring 620 is worn out too much, it can be directly replaced, reducing the maintenance cost.

[0063] Specifically, the motor 310 is a rod-type motor 310, the shaft of the rod-type motor 310 is passed through the cavity inside the reel 400, one end of the rod-type motor 310 in the axial direction is mounted on the box 600, and the other end is connected through the coupling 420. The rod-type motor 310 generally has a long shaft. If only one side of the rod-type motor 310 is fixed to the box 600, due to gravity, the other end of the rod-type motor 310 away from the box 600 will deviate downward, and greater shaking and noise will be generated when the rod-type motor 310 is running. By connecting the reel 400 through the coupling 420, the reel 400 can support and fix the rod-type motor 310, and the operation of the rod-type motor 310 is more stable.

[0064] The box body 600 further includes a fixing cover 630, which is connected to the outer surface of the box body 600 to limit the motor 310 on the box body 600. Specifically, a protrusion 311 is provided at one end of the motor 310 close to the fixing cover 630, and the fixing cover 630 is provided with a groove 631 adapted to the protrusion 311, and at least a part of the protrusion 311 is embedded in the groove 631 to limit the motor 310 on the box body 600.

[0065] In this embodiment, there are two fixing covers 630 , which are respectively disposed at opposite ends of the length direction of the box body 600 . In addition to fixing the motor 310 , the fixing covers 630 can also fix the end of the reel 400 on the box body 600 .

[0066] The box body 600 further includes a threaded connector, which is used to limit the fixing cover 630 on the side wall of the box body 600. The threaded end of the threaded connector passes through the fixing cover 630 and is threadedly connected to the threaded hole on the side wall of the box body 600. There are multiple threaded connectors, and the multiple threaded connectors are arranged at intervals along the circumference of the fixing cover 630. It can be understood that in other embodiments, the box body 600 can be provided with other fixing members to fix the fixing cover 630.

[0067] Combined with reference Figure 6 and Figure 7 Specifically, the box body 600 includes a first plate 601, a second plate 602 and a third plate 603 connected in sequence, and the first plate 601, the second plate 602 and the third plate 603 enclose a storage cavity for storing the roller blind 100, wherein any two adjacent ones of the first plate 601, the second plate 602 and the third plate 603 can be detachably connected.

[0068] It should be noted that in other embodiments, the box body 600 may also include a fourth plate, a fifth plate, a sixth plate, etc., and the present utility model does not limit this. As long as it meets the technical solution of including three plates that can be detachably connected in sequence, it should be within the protection scope of the present utility model.

[0069] Since the first plate 601, the second plate 602 and the third plate 603 are detachably connected, there will be gaps at the connection between the plates and at the storage place of the roller shutter 100, and rainwater and sewage may enter the storage cavity in the box 600 through these gaps. The accumulated rainwater and sewage will stink and corrode the box 600.

[0070] In order to solve this technical problem, specifically, the bottom wall of the box 600 is provided with a drainage channel 640, and the drainage channel 640 is connected to the outside. In this way, rainwater or sewage inside the box 600 can be discharged from the box 600 in time. Further, the box 600 is also provided with a filter cover 650, and the filter cover 650 is used to cover the drainage channel 640. The filter cover 650 is provided with multiple leakage channels for drainage at intervals, so that rainwater or sewage can be discharged from the box 600 through the drainage channel 640, while leaves, gravel and other debris are blocked to prevent debris from clogging the drainage channel 640. The user can regularly clean the debris on the filter cover 650.

[0071] Furthermore, in this embodiment, the number of the drainage channel 640 and the number of the filter cover 650 are both two, and the two drainage channels 640 are respectively arranged on opposite sides of the box body 600, and the position of the filter cover 650 matches the position of the drainage channel 640. In this way, it is possible to avoid rainwater or sewage accumulation on one side of the box body 600 due to the tilt of the box body 600. Of course, the manufacturer can also adjust the number of the drainage channels 640 and the filter cover 650 as needed.

[0072] Combined with reference Figure 8 and Figure 9 The roller shutter cover 10 further includes a drainage device 700, which is disposed at the front end of the slide rail 200. It can be understood that since the roller shutter 100 is connected to the slide rail 200, rainwater or sewage falling on the roller shutter 100 is collected on the slide rail 200 along the curtain blades 110 on the roller shutter 100. The drainage device 700 is connected to the slide rail 200, and can drain rainwater or sewage to prevent rainwater or sewage from wetting items in the cargo compartment.

[0073] In this embodiment, the number of the slide rails 200 and the number of the drainage devices 700 are both two. The two slide rails 200 are respectively arranged on opposite sides of the rolling curtain 100 to make the movement of the rolling curtain 100 smoother. The position of the drainage device 700 matches the position of the slide rail 200.

[0074] Specifically, a water collecting trough 210 is provided on the sliding rail 200, and a drain hole 710 is provided on the drainage device 700. The drain hole 710 is communicated with the water collecting trough 210. The water collecting trough 210 can collect the water flowing onto the sliding rail 200 and then drain it outside the rolling shutter cover 10 through the drain hole 710. The length extension direction of the water collecting trough 210 is parallel to the length extension direction of the sliding rail 200. In addition, the water collecting trough 210 extends from the front end in the length direction of the sliding rail 200 to the other end to improve the water collecting efficiency.

[0075] Furthermore, the drainage device 700 is detachably connected to the sliding rail 200 to facilitate the cleaning of sundries accumulated in the drain hole 710 and the drainage trough. In addition, the drainage device 700 is provided at the front end of the sliding rail 200 and is easily collided. Since the drainage device 700 is detachably installed on the sliding rail 200, it can be directly replaced when the drainage device 700 is damaged, reducing the maintenance cost. The specific detachable connection method of the drainage device can be threaded connection, snap connection, etc., and the present utility model does not limit this.

[0076] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art of the present utility model can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the scope defined by the spirit of the present utility model.
