Description

Technical Field

[0001] This utility model relates to car cargo covers, and more particularly to a retractable and foldable cargo cover. 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] To balance coverage and storage, some solutions have attempted to use foldable rigid panel structures. However, such structures often rely on simple hinge connections, lacking effective restraint and planar stability after unfolding. The sub-panels are prone to sagging or misalignment due to their own weight or vibration, resulting in an uneven curtain surface that negatively impacts both shading effectiveness and aesthetics.

[0006] Therefore, existing technologies face a triple dilemma: short rigid panels → incomplete shielding; long rigid panels → inability to be stored; foldable rigid panels → unstable unfolding. There is an urgent need for a new type of cargo cover structure that can extend the shielding range, achieve compact storage, and maintain rigidity and flatness in use, so as to truly achieve seamless shielding throughout the entire journey "from the roll-up box to the tailgate". Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a retractable and foldable blind to address the above-mentioned defects.

[0008] The technical solution adopted by this utility model to solve its technical problem is as follows: A retractable 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, and the main board and the secondary board are connected by a connecting device.

[0009] The connecting device includes a first hinge, a first limiting groove, a second limiting groove, a limiting plate, a motor, an electric push rod, and a transmission rod. The first hinge is disposed between the main plate and the sub-plate. The first limiting groove is disposed on the side of the main plate near the sub-plate. The second limiting groove is disposed on the side of the sub-plate near the main plate. The first limiting groove and the second limiting groove are located on the same horizontal line and are opposite to each other. The limiting plate is slidably disposed in the first limiting groove and the second limiting groove.

[0010] The limiting plate includes plate a, plate b, and a second hinge. Plate a is connected to plate b via the second hinge. The limiting plate is slidably disposed within the first limiting groove and the second limiting groove, and plate a can slide between the first limiting groove and the second limiting groove to span the seam between the main board and the sub-board.

[0011] The connecting device includes two sets arranged symmetrically on the curtain. The two sets of first limiting grooves have through grooves on their adjacent sides, which are connected to the inside of the first limiting grooves. The two ends of the transmission rod are respectively set in the through grooves and fixedly connected to the limiting plates in the first limiting grooves. The motor is fixedly set at the center of the back of the main board. One end of the electric push rod is fixedly connected to the output end of the motor and the other end is fixedly connected to the center of the transmission rod.

[0012] Furthermore, the first limiting groove and the second limiting groove have the same size specifications. The edge of the first limiting groove is flush with the edge of the main board near the sub-board, and the edge of the second limiting groove is flush with the edge of the sub-board near the main board.

[0013] Furthermore, the first hinge is a full-coverage right-angle hinge, and the second hinge is a damping hinge.

[0014] Furthermore, an opening is provided on the sub-plate.

[0015] Furthermore, the two ends of the transmission rod are slidably disposed in the through grooves on the side wall of the first limiting groove, and the two ends of the transmission rod pass through the through grooves and are fixedly connected to plate a in the first limiting groove. The transmission rod and plate a are always on the same vertical line.

[0016] Furthermore, the electric actuator and the transmission rod are arranged perpendicularly.

[0017] Furthermore, the main board and sub-board are made of ABS engineering plastic, while the curtain body is made of polyester fabric.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model achieves complete coverage of the tailgate area by rigidly supporting the sub-plate with a limiting plate (plate a) in the unfolded state, making the main plate and sub-plate coplanar to form an equivalently extended whole plate structure. This avoids the exposure of items or privacy leaks due to insufficient length. When the cargo cover needs to be rolled up, the electric push rod retracts, plate a returns to the first limiting groove, and the sub-plate, no longer constrained, can fold downwards around the first hinge to below the main plate. The overall thickness is significantly reduced, balancing the length requirements when unfolded and the space saving when folded, breaking through the structural limitations of traditional one-piece long plates.

[0020] 2. This utility model uses a damping hinge to connect the a plate and the b plate, which still has the ability to hover after folding, thus ensuring flatness when unfolded and avoiding shaking and abnormal noise in the folded state. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] Please see Figure 1-2 As shown, a retractable folding blind includes a blind 1, which includes a curtain body 101, a main board 102 and a secondary board 103. One end of the curtain body 101 is fixedly connected to the main board 102, and the main board 102 and the secondary board 103 are connected by a connecting device 2.

[0027] The connecting device 2 includes a first hinge 201, a first limiting groove 202, a second limiting groove 203, a limiting plate 204, a motor 205, an electric push rod 206, and a transmission rod 207. The first hinge 201 is disposed between the main plate 102 and the sub-plate 103. The first limiting groove 202 is disposed on the side of the main plate 102 near the sub-plate 103. The second limiting groove 203 is disposed on the side of the sub-plate 103 near the main plate 102. The first limiting groove 202 and the second limiting groove 203 are located on the same horizontal line and are opposite to each other. The limiting plate 204 is slidably disposed in the first limiting groove 202 and the second limiting groove 203.

[0028] The limiting plate 204 includes an a plate 3, a b plate 4, and a second hinge 5. The a plate 3 is connected to the b plate 4 through the second hinge 5. The limiting plate 204 is slidably disposed in the first limiting groove 202 and the second limiting groove 203, and the a plate 3 can slide between the first limiting groove 202 and the second limiting groove 203 to span the seam between the main plate 102 and the sub-plate 103.

[0029] The connecting device 2 includes two sets arranged symmetrically on the curtain 1. The two sets of first limiting grooves 202 have a through groove 6 on their adjacent sides. The through groove 6 is connected to the inside of the first limiting groove 202. The two ends of the transmission rod 207 are respectively set in the through groove 6 and fixedly connected to the limiting plate 204 in the first limiting groove 202. The motor 205 is fixedly set at the center of the back of the main board 102. One end of the electric push rod 206 is fixedly connected to the output end of the motor 205 and the other end is fixedly connected to the center of the transmission rod 207.

[0030] Furthermore, the first limiting groove 202 and the second limiting groove 203 have the same size and specifications. The edge of the first limiting groove 202 is flush with the edge of the main board 102 near the sub-board 103, and the edge of the second limiting groove 203 is flush with the edge of the sub-board 103 near the main board 102.

[0031] Furthermore, the first hinge 201 is a full-coverage right-angle hinge, and the second hinge 5 is a damping hinge. The use of damping hinges ensures that the hinges remain suspended even after folding, guaranteeing both flatness when unfolded and preventing wobbling and noise when folded.

[0032] Furthermore, an opening 7 is provided on the sub-panel 103. The opening 7 facilitates the pulling out of the curtain 1.

[0033] Furthermore, the two ends of the transmission rod 207 are slidably disposed in the through groove 6 on the side wall of the first limiting groove 202, and the two ends of the transmission rod 207 pass through the through groove 6 and are fixedly connected to the a plate 3 in the first limiting groove 202. The transmission rod 207 and the a plate 3 are always on the same vertical line.

[0034] Furthermore, the electric push rod 206 is arranged perpendicularly to the transmission rod 207.

[0035] Furthermore, the main board 102 and the sub-board 103 are made of ABS engineering plastic, while the curtain body 101 is made of polyester fabric. The main board 102 and the sub-board 103 are made of ABS engineering plastic, which is lightweight and high-strength; the curtain body 101 is made of polyester fabric, which is flexible and durable; the overall structure is symmetrically arranged, suitable for the trunk space of various car models, and has good industrialization prospects.

[0036] Please refer to the embodiments of this utility model. Figures 1-2 After adopting the above structure, the retractable box is assembled on the car trunk. When the cargo cover 1 is pulled back, and the end of the cargo cover 1 is still some distance from the tailgate and cannot be covered, the motor 205 is started. The output end of the motor 205 pushes the electric push rod 206 towards the tailgate. Simultaneously, the electric push rod 206 pushes the transmission rod 207 along the tailgate. Since the two ends of the transmission rod 207 are respectively slidably disposed in the through grooves 6 on the side walls of the upper and lower first limiting grooves 202, and the through grooves 6... Connected to the first limiting groove 202, the two ends of the transmission rod 207 are fixedly connected to plate a 3 within the first limiting groove 202. As the transmission rod 207 moves, plate a 3 also moves along the direction of the tailgate. Since the first limiting groove 202 and the second limiting groove 203 are of the same size and on the same horizontal line, plate a 3 can slide horizontally, detaching from the first limiting groove 202 and entering the second limiting groove 203, spanning the joint between the main plate 102 and the sub-plate 103. At this time, plate a 3 is positioned between the main plate 102 and the sub-plate 103. Due to the support of plate a 3, the main plate 102 and the sub-plate 103 can simultaneously be in a flat state. Plate a 3, horizontally positioned between the mating surfaces of the main plate 102 and the sub-plate 103, provides lateral support, effectively suppressing the sagging or misalignment of the sub-plate 103 caused by its own weight or vehicle vibration, thus preventing unevenness of the curtain surface. By rigidly supporting the sub-plate 103 with plate a 3 in the unfolded state, the main plate 102 and the sub-plate 103 are coplanar to form an equivalently extended whole plate structure, thereby achieving complete coverage of the tailgate area of ​​the trunk and avoiding the exposure of items or leakage of privacy due to insufficient length.

[0037] When the cargo cover 1 needs to be rolled up, the motor 205 is started. The output end of the motor 205 pulls back the electric push rod 206, causing the transmission rod 207 to move away from the tailgate. At this time, one end of plate a 3 will retract from the second limiting groove 203, and finally make plate a 3 completely within the first limiting groove 202. The second hinge 5 between plate a 3 and plate b 4 and the gap between the main plate 102 and the sub-plate 103 coincide. When plate a 3 is completely retracted into the first limiting groove 202, the joint between the main plate 102 and the sub-plate 103 loses its restraint, and the sub-plate 103 can be folded downward around the first hinge 201, so that the sub-plate 103 is folded below the main plate 102. The second hinge 5 uses a damping hinge, so that the sub-plate 103 still has a certain hovering function. This prevents the sub-plate 103 from vibrating and making abnormal noise when the car is moving due to the lack of restraint.
