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 may mean A or B; "and / or" herein is merely a description of the relationship between associated objects, indicating that three relationships may exist. For example, A and / or B may mean: A exists alone, A and B exist simultaneously, and B exists alone, these three situations.
[0042] Unless otherwise clearly specified and defined, the terms "arranged", "connected", and "coupled" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components.
[0043] In the existing roll-up covers for pickup trucks, the friction between the roll-up curtain and the slide rail is large, which easily generates noise and the roll-up curtain is easily damaged. The bumps during the vehicle's driving can cause the vibration of the roll-up curtain, and the shock absorption performance of the roll-up curtain is poor, resulting in a short service life.
[0044] To solve the above-mentioned at least one technical problem, the present utility model provides a roll-up curtain 100 and a roll-up cover 10 including the roll-up curtain.
[0045] Refer to Figure 1 、 Figure 2 and Figure 3 , the roll-up cover 10 is used to shield the cargo box of the pickup truck. The roll-up curtain 100 has the Figure 1 shown open state and the Figure 2 shown storage state. When the roll-up curtain 100 is in the open state, the roll-up cover 10 can prevent the goods in the cargo box from being blown by the wind and rained on. When the roll-up curtain 100 is in the storage state, the user can carry goods into the cargo box. It can be understood that in addition to being able to be used to shield the rear cargo box of the pickup truck, the roll-up curtain 100 can also be used to shield transport vehicles such as cars and heavy-duty trucks. In addition, the roll-up curtain 100 can also be used for non-transport tools such as roll-up curtain doors.
[0046] The roll-up cover 10 further includes a slide rail 200. One end of the roll-up curtain 100 in the length direction is connected to the slide rail 200, and the roll-up curtain 100 can move on the slide rail 200.
[0047] It should be noted that the "length direction" and "width direction" appearing throughout the text of the present utility model are as Figure 1As shown, the "length direction" refers to the direction perpendicular to the moving direction of the rolling curtain 100, and the "width direction" refers to the direction parallel to the moving direction of the rolling curtain 100. The "length direction" and the "width direction" have nothing to do with the specific numerical values.
[0048] Refer to Figure 4 , the rolling curtain 100 includes a plurality of curtain leaves 110, bearings 120, and rotating shafts 130 that are connected in sequence. The bearings 120 are arranged on the side surfaces of the curtain leaves 110 and can rotate around their central axes. The rotating shafts 130 pass through the curtain leaves 110 and the bearings 120 to fix the bearings 120 on the curtain leaves 110. At least part of the bearings 120 is arranged on the slide rail 200, and the bearings 120 can move on the slide rail 200. The curtain leaves 110 can move under the action of an external force, and the bearings 120 move on the slide rail 200, so that the rolling curtain 100 can be switched between the open state and the storage state. It can be understood that the rotating shaft 130 can also be integrally formed with the curtain leaf 110. At this time, the rotating shaft 130 is a part of the curtain leaf 110.
[0049] In the present utility model, since the bearings 120 are provided on the rolling curtain 100, the contact between the curtain leaves 110 and the slide rail 200 is changed to the contact between the bearings 120 and the slide rail 200. The movement of the bearings 120 drives the movement of the curtain leaves 110, reducing the frictional resistance. At the same time, the bearings 120 have better shock absorption and buffering performance, reducing the noise generated by the movement of the curtain leaves 110.
[0050] In this embodiment, refer to Figure 4 and Figure 5 , two bearings 120 are correspondingly provided for each curtain leaf 110. The two bearings 120 are respectively arranged at the opposite ends of the curtain leaf 110 in the length direction, and the central axes of the two bearings 120 located on the same curtain leaf 110 are collinear. In this way, the forces and moving speeds at both ends of the curtain leaf 110 in the length direction are basically the same during the movement process. The parts at both ends of the curtain leaf 110 in the length direction will not collide with the slide rail 200, and the curtain leaf 110 will not be displaced, increasing the frictional resistance. Of course, the manufacturer can also set only one bearing 120 according to needs, and the present utility model does not limit this.
[0051] The rolling curtain 100 further includes a bearing bracket 140, and the bearing bracket 140 is arranged on the side of the bearing 120 away from the curtain leaf 110. The bearing bracket 140 can fix the bearing 120 to prevent the bearing 120 from being displaced. In addition, the bearing bracket 140 can also support the curtain leaf 110 to prevent the edge of the curtain leaf 110 from deforming too much.
[0052] Specifically, the upper surface of the bearing bracket 140 is flush with the upper surface of the curtain leaf 110, which avoids the bearing bracket 140 affecting the folding and storage of the curtain leaf 110 and can also prevent the bearing bracket 140 from protruding from the curtain leaf 110 and bumping into people's hands. In addition, the lower surface of the bearing bracket 140 is parallel to the lower surface of the curtain leaf 110, which avoids affecting the folding and storage of the curtain leaf 110.
[0053] Further, with reference to Figure 7 and Figure 10 , a protruding portion 141 is provided on one side of the bearing bracket 140 close to the curtain leaf 110. The interior of the curtain leaf 110 has a cavity 111 and the cavity 111 has an opening facing the bearing bracket 140. When the bearing bracket 140 is installed on the curtain leaf 110, the protruding portion 141 enters through the opening and fits into the cavity 111 so that the bearing bracket 140 is sleeved on the side surface of the curtain leaf 110. In this way, the bearings 120 can be stably installed on the side surface of the curtain leaf 110 without the need for additional fixing components.
[0054] In this embodiment, each curtain leaf 110 is provided with two bearings 120 and two bearing brackets 140. The two bearing brackets 140 are respectively arranged at opposite ends in the length direction of the curtain leaf 110. The position of the bearing bracket 140 is adapted to the position of the bearing 120, that is, for each bearing 120 provided, a bearing bracket 140 is provided on the side of the bearing 120 away from the curtain leaf 110. In this way, the movement of the bearings 120 and the curtain leaf 110 can be made smoother, and the vibration of the curtain leaf 110 can be reduced.
[0055] Specifically, with reference to Figure 6 , Figure 8 and Figure 9 , two adjacent curtain leaves 110 are hinged to each other. Hooks 112 and rotating portions 113 are respectively provided at opposite ends in the width direction of the curtain leaf 110. The rotating portion 113 of each curtain leaf 110 is sleeved in the hook 112 of the adjacent curtain leaf 110, and the curtain leaf 110 can rotate relative to the adjacent curtain leaf 110 around its rotating portion 113. The two adjacent curtain leaves 110 can rotate relative to each other, which is convenient for the folding and storage of the curtain leaf 110, and the curtain leaves 110 can be closely attached to each other after folding and storage, and the space occupied by the rolling curtain 100 is smaller.
[0056] Further, with reference to Figure 5 , Figure 6 and Figure 7 , the interior of the rotating portion 113 is a hollow structure, and the central axis of the rotating portion 113 is collinear with the central axis of the bearing 120. The rotating shaft 130 passes through the rotating portion 113 and the bearing 120. In this way, the relative rotation of the curtain leaf 110 bracket and the movement of the bearing 120 can be made smoother, the movement of the rolling curtain 100 can be made more stable, and the vibration during the movement of the rolling curtain 100 can be reduced.
[0057] Further, in combination with reference Figure 5 and Figure 8 , the barb 112 extends from one end to the other end in the length direction of the rolling curtain 100, and the rotating part 113 extends from one end to the other end in the length direction of the curtain leaf 110. In this way, the relative rotation between adjacent curtain leaves 110 is more stable, and the movement of the rolling curtain 100 is more stable. In addition, the barb 112 and the rotating part 113 can also support the curtain leaf 110, preventing the overall deformation of the curtain leaf 110 from being too large and reducing the swaying of the curtain leaf 110 during movement.
[0058] Specifically, referring to Figure 7 , the bearing 120 is a rolling bearing 120. The rolling bearing 120 includes a plurality of rolling elements arranged circumferentially inside. The rolling bearing 120 can roll on the slide rail 200 to further reduce the frictional resistance. It can be understood that the manufacturer can also use a sliding bearing 120 to replace the rolling bearing 120 according to needs. The effect of reducing the frictional resistance of the sliding bearing 120 is not as good as that of the rolling bearing 120, but the load-bearing capacity of the sliding bearing 120 is stronger.
[0059] In this embodiment, referring to Figure 8 and Figure 9 , the curtain leaf 110 includes a front part 114, a middle part 115, and a rear part 116 arranged in sequence along its width direction. The rotating part 113 is connected to the front part 114, and the barb 112 is connected to the rear part 116. The thickness of the rear part 116 is greater than the thickness of the middle part 115, and the thickness of the middle part 115 is greater than the thickness of the front part 114. It can be understood that during the storage process of the rolling curtain 100, two adjacent curtain leaves 110 will overlap and fold, and the parts of the curtain leaf 110 in contact with the adjacent curtain leaf 110 are the rotating part 113, the front part 114, the middle part 115, the rear part 116, and the barb 112 in sequence. Therefore, by setting the thickness of the front part 114 < the thickness of the middle part 115 < the thickness of the rear part 116, with the thickness generally showing an increasing trend, the overlapping and folding between adjacent curtain leaves 110 is smoother, reducing vibration and noise.
[0060] Specifically, the thickness of the front part 114 increases from the side away from the middle part 115 to the side close to the middle part 115 along its width direction, and the thickness of the rear part 116 increases from the side close to the middle part 115 to the side away from the middle part 115 along its width direction. In this way, the resistance to the overlapping and folding between adjacent curtain leaves 110 can be reduced. Further, an avoidance space 117 is provided between the front part 114 and the rotating part 113, and this avoidance space 117 is used for the barb 112 to rotate.
[0061] Specifically, continue to refer to Figure 2, a track groove 210 for carrying the bearing 120 is provided on the sliding rail 200, and the length extension direction of the track groove 210 is parallel to the length extension direction of the sliding rail 200. By providing the track groove 210, the displacement or detachment of the bearing 120 from the sliding rail 200 during the movement of the rolling curtain 100 can be prevented, and the movement of the bearing 120 is smoother.
[0062] Further, the number of the sliding rails 200 is two, and the two sliding rails 200 are respectively arranged at the opposite ends in the length direction of the curtain leaf 110. By arranging the sliding rails 200 at both ends, the forces and movements at both ends in the length direction of the curtain leaf 110 are basically the same, and the movement of the rolling curtain 100 is smoother and more stable.
[0063] In this embodiment, the rolling curtain cover 10 further includes a driving device 300. One end of the rolling curtain 100 is connected to the driving device 300, and the driving device 300 is used to drive the rolling curtain 100 to switch between the open state and the storage state. It can be understood that in other embodiments, the rolling curtain cover 10 may not be provided with the driving device 300, but the movement of the rolling curtain 100 is driven manually. Or, the rolling curtain cover 10 is provided with the driving device 300, but there are two driving modes, namely manual driving and driving by the driving device 300, for the rolling curtain cover 10 at the same time.
[0064] Specifically, the driving device 300 is a driving motor 310, and the driving motor 310 can rotate forward or backward to drive the rolling curtain 100 to switch between the open state and the storage state. It can be understood that in other embodiments, the driving device 300 may also be a cylinder, a magnetic pole driver, etc.
[0065] In this embodiment, with reference to Figure 3 and Figure 5 , a transmission shaft 150 is provided at one end of the rolling curtain 100, a transmission bracket 320 is provided on the driving motor 310, the transmission shaft 150 is connected to the transmission bracket 320, and the driving motor 310 drives the transmission shaft 150 to move through the transmission bracket 320 to drive the rolling curtain 100. Specifically, the number of the transmission shafts 150 and the transmission brackets 320 is two each. The transmission shafts 150 are respectively arranged at the opposite ends in the length direction of the curtain leaf 110, and the position of the transmission bracket 320 matches the position of the rotating shaft.
