[0039] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various variations in different embodiments without departing from the scope of the present invention, and that the descriptions and illustrations herein are intended to be illustrative in nature and not to limit the present invention.

[0040] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. In addition, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist, for example, A and / or B can mean: the existence of A alone, the existence of A and B at the same time, and the existence of B alone.

[0041] Unless otherwise clearly specified and limited, the terms "set", "connected" and "connected" 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 a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two elements.

[0042] In the existing rolling shutter cover, if a person or an object accidentally enters the cargo compartment during the movement of the rolling shutter blades, it may easily cause personal injury or damage to objects, posing a safety hazard.

[0043] In order to solve at least one of the above technical problems, the present invention provides a rolling shutter tail cover 110 and a rolling shutter cover 10 including the rolling shutter tail cover 110 .

[0044] refer to Figure 1 、 Figure 2 and Figure 3 The roller shutter cover 10 is used to cover the cargo box of a pickup truck. The roller shutter 100 has Figure 1 The open state shown and Figure 2 In the stowed state shown, when the roller shutter 100 is in the open state, the roller shutter cover 10 can protect the cargo in the cargo compartment from being exposed to wind and rain. When the roller shutter 100 is in the stowed state, the user can carry cargo in the cargo compartment. It is understood that the roller shutter 100 can be used to shield not only the rear compartment of a pickup truck, but also other transport vehicles such as cars and heavy trucks.

[0045] The rolling shutter cover 10 includes a rolling shutter 100 and a slide rail 200. The rolling shutter 100 includes a rolling shutter tail cover 110 and a plurality of curtain blades 120 connected in sequence. The rolling shutter 100 is connected to the slide rail 200 and can move on the slide rail 200 to switch the rolling shutter 100 between an open state and a stored state.

[0046] Specifically, refer to Figure 4 The roller shutter tail cover 110 includes a cover body 111, a limit switch 112, and a limit device 113. The limit switch 112 is disposed on the cover body 111, and the limit device 113 is connected to the limit switch 112. During the movement of the roller shutter tail cover 110, when the limit switch 112 is touched, the limit switch 112 activates the limit device 113, and the limit device 113 works to limit the movement of the roller shutter tail cover 110. It is understood that the limit switch 112 can activate the limit device 113 by mechanical connection or by electrical signal connection. The electrical signal connection can be by wired connection or wireless signal connection. The wireless signal connection can be a Bluetooth connection, a WIFI connection, etc.

[0047] In the present utility model, since a limit switch 112 and a limit device 113 are provided, during the movement of the roller shutter tail cover 110, if the roller shutter tail cover 110 touches a human body or other objects and causes the limit switch 112 to operate, the limit switch 112 activates the limit device 113, and the limit device 113 limits the movement of the roller shutter tail cover 110, thereby avoiding the roller shutter tail cover 110 from pinching hands or other objects, thereby reducing safety risks.

[0048] Combined with reference Figure 4 and Figure 5 In this embodiment, the cover body 111 includes an upper cover 114 and a lower cover 115 arranged in sequence in the height direction. The upper cover 114 is movably connected to the lower cover 115 and can slide relative to the lower cover 115. The upper cover 114 has a front end 1141 that protrudes from the outer surface of the lower cover 115, and a limit switch is provided on the lower cover 115. During the movement of the roller shutter tail cover 110, the front end 1141 can be touched, causing the upper cover 114 to slide relative to the lower cover 115, so that the upper cover 114 abuts the limit switch 112.

[0049] It should be noted that the terms “length” and “height” appearing throughout this utility model are as follows: Figure 1 As shown, the “length direction” refers to the direction perpendicular to the moving direction of the rolling blind 100 , and the “height direction” refers to the vertical upward direction. The “length direction” and the “height direction” have nothing to do with specific numerical values.

[0050] It should be noted that in some possible embodiments, the limit switch 112 is disposed on the outer surface of the front end portion 1141 or an infrared recognition device is provided to enable recognition between the limit switch 112 and a person or object. However, these embodiments all present the problem of easily erroneously triggering the limit device 113. For example, leaves, paper scraps, etc. falling onto the infrared recognition device may trigger the limit device 113, or small gravel, raindrops, etc. may hit the outer surface of the limit switch 112 and erroneously trigger the limit device 113. Furthermore, the limit switch 112 disposed on the outer surface is susceptible to damage due to wind, rain, bumps, and the like.

[0051] In the present invention, the limit switch 112 is disposed inside the cover 111, reducing the risk of damage from exposure to the outside world and avoiding the risk of accidental triggering due to direct contact with leaves, paper scraps, etc. Furthermore, the upper cover 114 needs to slide a certain distance relative to the lower cover 115 in order to contact the limit switch 112, and there is frictional resistance between the upper cover 114 and the lower cover 115. Therefore, the external force acting on the upper cover 114 must be greater than a preset threshold (the preset threshold is determined by the sliding resistance between the upper cover 114 and the lower cover 115). Therefore, when light objects such as leaves and gravel touch the upper cover 114, the limit switch 112 will not be triggered, further reducing the risk of accidental triggering of the limit device 113.

[0052] Specifically, Figure 4 It is shown that the roller shutter tail cover 110 also includes a side bracket 116, which is sleeved on one end of the lower cover 115 in the length direction. A sliding groove 1161 is provided on the side of the side bracket 116 close to the upper cover 114. One end of the roller shutter tail cover 110 in the length direction is inserted into the sliding groove 1161 so that the upper cover 114 can slide relative to the lower cover 115, and the upper cover 114 will not be separated from the lower cover 115.

[0053] Furthermore, there are two side brackets 116, located at opposite ends of the length of the lower cover 115. The opposite ends of the length of the upper cover 114 are respectively inserted into corresponding sliding grooves 1161. This ensures that the forces and movements at both ends of the length of the roller shutter tail cover 110 are substantially consistent, making the movement of the roller shutter tail cover 110 smoother and more stable. It is understood that the manufacturer can adjust the number of side brackets 116 as needed, and this is not limited by the present invention.

[0054] Specifically, with reference to Figure 4 and Figure 5 , Figure 5The diagram shows that the upper cover 114 is provided with an L-shaped plate 1142 protruding from its lower surface, and the lower cover 115 is provided with an abutment portion 1151 protruding from its upper surface. The abutment portion 1151 is provided with a cavity 1152, and the opening of the cavity 1152 faces the L-shaped plate 1142. The limit switch 112 is located on the side wall of the cavity 1152. Under the action of an external force, the front end of the L-shaped plate 1142 can move the opening of the cavity 1152 into the cavity 1152 and abut the limit switch 112.

[0055] There are two limit switches 112, located at opposite ends of the length of the lower cover 115. This ensures a more even force from the upper cover 114 on the lower cover 115, preventing deformation of the lower cover 115 caused by long-term, one-sided impact from the upper cover 114. Of course, manufacturers can adjust the number of limit switches 112 and L-shaped plates 1142 as needed, and this is not a limitation of the present invention.

[0056] Specifically, with reference to Figure 5 and Figure 6 , Figure 6 The diagram shows that the upper cover 114 is provided with a horizontally extending protrusion 1143, and a limiting cavity 1153 is provided on the side of the lower cover 115 near the protrusion 1143. At least a portion of the protrusion 1143 is embedded in the limiting cavity 1153, and the upper surface of the protrusion 1143 abuts the top wall of the limiting cavity 1153 to limit the height movement of the upper cover 114. After the upper cover 114 hits the lower cover 115, due to inertia, the front end 1141 tends to tilt upward. When the upper cover 114 tilts up to a certain angle, it may become stuck and unable to slide relative to the lower cover 115. The provision of the protrusion 1143 and the limiting cavity 1153 can prevent the upper cover 114 from tilting up, thus avoiding the upper cover 114 from getting stuck.

[0057] Furthermore, the upper surface of the protrusion 1143 has an arcuate portion that abuts the top wall of the retaining cavity 1153. This reduces the frictional resistance to movement of the upper cover 114 caused by the abutment between the upper surface of the protrusion 1143 and the top wall of the retaining cavity 1153. In some possible embodiments, the arcuate portion is made of a deformable elastic material to further reduce the frictional resistance to movement of the upper cover 114.

[0058] Specifically, continue to refer to Figure 4 The limit switch 112 is a micro-touch switch, and the micro-touch switch has a micro-touch plate 1121. By setting the micro-touch plate 1121, the sensitivity of the limit switch 112 can be improved. Of course, the manufacturer can also set the limit switch 112 to other switches available on the market as needed.

[0059] Specifically, the limiting device 113 is a lock body 1131 disposed within the cover 111. The lock body 1131 has a locking tongue 1132 that movably extends through the cover 111. The locking tongue 1132 can extend from the cover 111 and abut against the slide rail 200 to limit the movement of the cover 111. In this embodiment, the lock body 1131 is provided with two locking tongues 1132, one at each of the opposite ends of the length of the cover 111. The two locking tongues 1132 can simultaneously extend from the cover 111 to limit the movement of the cover 111. The provision of locking tongues 1132 at both ends of the cover 111 allows both ends of the cover 111 to be restrained, preventing deformation and shaking of the other end caused by restraining only one end.

[0060] Specifically, with reference to Figure 4 and Figure 7 The roller shutter tail cover 110 also includes an elastic damper 118 for reducing impact. Two elastic dampers 118 are located on opposite sides of the cover 111 along its length. The elastic dampers 118 deform to reduce vibration and impact caused by contact with the roller shutter tail cover 110, providing a cushioning effect. It is understood that manufacturers can freely adjust the type and number of elastic dampers 118 as needed.

[0061] Combined with reference Figure 4 and Figure 6 In this embodiment, the roller shutter tail cover 110 further includes a light strip 117, which is provided on the cover body 111. In this way, different lighting effects can be achieved by controlling the on and off, flashing, light color, etc. of the light strip 117.

[0062] Specifically, the light strip 117 includes a brake indicator light 1171, which is disposed on the outer surface of the cover 111. The brake indicator light 1171 is configured to be activated or deactivated according to the vehicle's state of motion. For example, when the vehicle brakes, the brake indicator light 1171 activates and flashes continuously to warn other vehicles.

[0063] The light strip 117 also includes a lighting strip 1172, which is disposed on the outer surface of the upper cover 114 and / or the lower cover 115. Specifically, in this embodiment, both the upper cover 114 and the lower cover 115 are provided with the lighting strip 1172. The lighting strip 1172 is disposed on the lower surface of the lower cover 115. The lower surface of the lower cover 115 is provided with a slot, into which the lighting strip 1172 is inserted and secured. The side of the upper cover 114 is provided with a slot, into which the lighting strip 1172 is inserted and secured. The length of the lighting strip 1172 extends parallel to the length of the cover 111, and at least part of the light path of the lighting strip 1172 enters the vehicle interior. Of course, in addition to being used for illumination, the lighting strip 1172 can also provide lighting effects such as different color changes and flashing.

[0064] Specifically, the roller shutter tail cover 110 further includes a circuit board, which is disposed within the cover body 111 and electrically connected to the light strip 117. The circuit board is used to control the activation and deactivation of the light strip 117. Furthermore, the circuit board can also control lighting effects such as the flashing and color of the light strip 117. It is understood that in other embodiments, the circuit board can also be disposed on other components of the roller shutter cover 10, for example, the circuit board can be disposed on the slide rail 200.

[0065] Specifically, the roller shutter tail cover 110 also includes a power source for powering the light strip 117. The power source can be a dry cell battery, a rechargeable power bank, or the like. Alternatively, the roller shutter tail cover 110 can be connected to an external power source by providing a power interface or power cord. Furthermore, the roller shutter tail cover 110 can also be provided with interfaces or wires for both the power source and the external power source.

[0066] Therefore, the manufacturer can freely configure the circuit board and the power supply as needed to achieve the purpose of powering and controlling the light strip 117, and the present invention does not impose any limitation on this.

[0067] Specifically, in one embodiment, a light strip 117 is provided on the slide rail 200. The light strip 117 provided on the slide rail 200 is similar to the light strip 117 provided on the roller shutter tail cover 110 and will not be described in detail herein. Of course, the light strip 117 on the slide rail 200 may also be omitted.

[0068] Continue to refer Figure 1 The rolling shutter cover 10 also includes a drive motor 300 for driving the rolling shutter 100. The drive motor 300 is connected to one end of the rolling shutter 100 and can drive the rolling shutter 100 on the slide rail 200 to switch the rolling shutter 100 between an open state and a stowed state. Of course, the rolling shutter cover 10 can also be operated manually without the drive motor 300. Alternatively, the rolling shutter cover 10 can be equipped with a drive motor 300 and have both an electric mode and a manual mode.

[0069] In another embodiment, the limit device 113 is a motor controller capable of controlling the operation of the drive motor 300. The limit switch 112 is connected to the motor controller via a wired connection or a wireless signal connection. For example, the specific control process is as follows: when the cover 111 is touched and the limit switch 112 is triggered, the limit switch 112 transmits an electrical signal to the motor controller, which then shuts down the drive motor 300.
