Description

Technical Field

[0001] This utility model relates to car cover curtains, and more particularly to a foldable car cover curtain. Background Technology

[0002] Car cargo covers are typically installed in roll-up boxes on the inner walls of the trunk. By pulling out the cover, items inside the trunk are concealed, protecting privacy and enhancing aesthetics. To ensure a smooth and even coverage, some products integrate a horizontal rigid plate at the end of the cover, allowing the fabric to be stretched taut when unfolded.

[0003] However, since the retractable box is usually installed in the front part of the side wall of the trunk, even when the curtain is fully extended, there is still a longitudinal gap (usually 10–25 cm) between the end of the hard panel and the inside of the tailgate. This gap means that the cargo cover cannot truly cover the rearmost part of the trunk, and the contents can still be seen through the tailgate glass from outside the vehicle, thus weakening the concealment function.

[0004] If an attempt is made to fill the gap by extending the length of the hardboard, the overall structure will become too long. When the cargo cover is retracted, the extended hardboard will not be fully retracted into the storage box because it exceeds the space limit behind the retractor box (such as being blocked by the C-pillar liner, spare tire compartment, or tailgate hinge area), resulting in the hardboard being exposed, interfering with tailgate closure, or even damaging the cover or mechanism.

[0005] Therefore, existing technologies face a dilemma: short rigid boards result in incomplete shielding; long rigid boards make storage impossible. There is an urgent need for a new structure that can both extend the shielding range and achieve compact storage, in order to truly achieve seamless shielding throughout the entire journey "from the reel box to the tailgate". Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a foldable blind curtain to address the above-mentioned defects.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: a foldable blind curtain, including a blind curtain, the blind curtain including a curtain body, a main board and a secondary board, one end of the curtain body is fixedly connected to the main board, the main board is disposed between the curtain body and the secondary board, the secondary board is disposed on the side away from the roll-up box, and the secondary board is hinged to the main board through a hinge.

[0008] The curtain is equipped with a locking and positioning device, which includes a button, a locking block, a storage chamber, spring A, spring B, and a pull cord. The storage chamber is located on the side of the main board facing away from the hinge. The locking block is slidably located in the storage chamber, and a limit rod is located at the bottom of the locking block. Spring A is sleeved on the limit rod. The bottom of the storage chamber has a storage groove for the limit rod to be inserted. The opening of the storage groove matches the diameter of the limit rod. The size of spring A is larger than the opening diameter of the storage groove. An opening is located in the middle of the side of the sub-plate away from the main board. The button is located in the opening on the side away from the main board. A button slot is located below the button at the opening for the button to be inserted. The bottom of spring B is fixedly located in the button slot, and the top of spring B is fixedly connected to the button. A through groove is located in the sub-plate for the pull cord to pass through. One end of the through groove is located at the junction of the sub-plate and the main board and below the storage chamber. The other end of the through groove is connected to the button slot. One end of the pull cord is fixedly connected to the bottom of the limit rod, and the other end is fixedly connected to the bottom of the button.

[0009] Furthermore, the hinges at both ends of the motherboard are three-position folding hinges, and the hinges are all located at the bottom of the motherboard.

[0010] Furthermore, the opening of the storage compartment is flush with the edge of the motherboard.

[0011] Furthermore, the main board and sub-board are made of ABS engineering plastic, while the curtain body is made of polyester fabric.

[0012] Furthermore, Velcro is installed on both sides of the curtain, and reflective strips are installed on the Velcro.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model divides the cargo cover into a curtain body, a main board, and a secondary board. The curtain body and the main board are integrally formed, the main board is located between the curtain body and the secondary board, and the secondary board is located on the side away from the retractor box. The secondary board is hinged to the main board via a three-position folding hinge. As an extendable end rigid component, the secondary board, together with the main board, forms an extended support frame when unfolded, effectively bridging the gap between the retractor box and the tailgate. This allows the curtain body to fit snugly against the rearmost area of ​​the trunk, completely eliminating blind spots and improving privacy. The secondary board, connected to the main board via a hinge, can fold inward during storage, significantly shortening the overall longitudinal length of the cargo cover. This avoids interference with the vehicle body structure and ensures that the entire component (including the rigid parts) can be completely stored in the factory-installed retractor box without affecting the normal closing of the tailgate.

[0015] 2. This utility model incorporates a locking and positioning device, comprising a button, a locking block, a storage chamber, spring A, spring B, and a pull cord. By pressing the button within the opening, the pull cord at the bottom of the button is pulled downwards. This pull cord then pulls a limiting rod, causing the limiting rod to move into the storage slot. This allows control over the length of the curtain being pulled out, enabling customization of the coverage. During the curtain's extension, the user can release the button at any time, based on the actual height or width of items in the trunk, allowing the locking block to automatically engage with the corresponding slot on the vehicle body. This allows for flexible setting of the coverage area, preventing over- or under-coverage and improving usability. Under the continuous thrust of spring A, the locking block always tends to pop outwards. Once engaged, it remains stably locked even during vehicle movement or vibrations, preventing accidental retraction and ensuring a persistent and effective covering. Attached Figure Description

[0027] Furthermore, the opening 6 of the storage compartment 303 is flush with the edge of the mainboard 102, allowing the card block 302 to fit more snugly into the card slot on the edge of the trunk.

[0028] Furthermore, the main board 102 and the secondary board 103 are made of ABS engineering plastic, and the curtain body 101 is made of polyester fabric.

[0029] Furthermore, Velcro is provided on both sides of the curtain body 101, and reflective strips are provided on the Velcro. The Velcro with reflective strips on both sides of the curtain body 101 is hidden and stored in the normal state. The Velcro is provided with disposable tape, which can be quickly removed and pasted to the rear of the vehicle or the road in an emergency to form a highly visible reflective warning strip, which helps to improve driving safety at night or in low visibility environments, and realizes the dual function of concealment and emergency.

[0030] Please refer to the embodiments of this utility model. Figures 1-5 With the above structure, after the roll-up box is installed on the car trunk, the curtain 101 can be pulled out from the roll-up box by pulling the opening 6 on the sub-plate 103. Several slots are provided on both sides of the track along which the curtain 101 is pulled in the trunk. When the curtain 101 is pulled out, the button 301 inside the opening 6 can be pressed, and the pull cord 306 at the bottom of the button 301 will be pulled downwards. At this time, the other end of the pull cord 306 will pull the limiting rod 4, causing the limiting rod 4 to move into the storage slot 5. At this point, the length of the curtain 101 pulled out can be controlled, and the coverage of the cargo cover 1 can be customized. When locking is required, release button 301. At this time, under the push of spring B305, button 301 will lift upward, and pull cord 306 will be released. Simultaneously, in the storage compartment 303, since the other end of pull cord 306 is no longer pressed by button 301, the limiting rod 4 will spring out from the storage slot 5 under the push of spring A304. The locking block 302 will protrude from the storage compartment 303, so that the locking block 302 can be set in the slots on both sides of the track along which the curtain 101 is pulled in the trunk. At this time, the driver can control the coverage area of ​​the cargo cover 1 according to his own needs.

[0031] Please refer to the embodiments of this utility model. Figures 1-5 The hinges 2 at both ends of the panel are three-position folding hinges, all located at the bottom of the main board 102. Passengers can manually press the hinges 2 at both ends of the main board 102. When the sub-panel 103 is at 0°, i.e., folded below the main board 102, it is connected to the main board 102 via hinges 2. During storage, it can fold inwards, significantly shortening the overall longitudinal length of the cargo cover 1, thus avoiding interference with the vehicle body structure and ensuring the entire component (including rigid parts) can be completely stored in the factory-pre-installed retractable box without affecting the normal closing of the tailgate. When the sub-panel 103 is at 180°, i.e., fully flat, it acts as an extendable end rigid component. In its unfolded state, the sub-panel 103, together with the main board 102, forms an extended support frame, effectively bridging the gap between the retractable box and the tailgate. This allows the curtain 101 to fit snugly against the rearmost area of ​​the trunk, completely eliminating blind spots and improving privacy.
