Description

Technical Field

[0001] This invention belongs to the field of automotive parts technology, specifically relating to a sliding tray for storage in the rear trunk of a pickup truck. Background Technology

[0002] With market restructuring, pickup trucks, thanks to their load-bearing capacity and versatility, are finding increasingly wider applications. The pickup truck's rear cargo bed is an open-top design, and users are demanding more diverse functions from these beds. A new type of pickup truck rear cargo bed sliding tray perfectly meets this market need. Through the rolling of wheels, it increases load-bearing capacity while making pushing and pulling effortless, easily facilitating the storage and loading / unloading of items in the rear cargo bed. Furthermore, this device can be quickly disassembled, making it convenient for owners to place large items such as motorcycles, all-terrain vehicles, and lawnmowers.

[0003] Existing pickup truck pallet designs involve a guide rail bracket mechanism fixed to the bottom of the vehicle, with guide pulleys on the guide rails. The pallet extends by pushing and pulling, facilitating loading and unloading of goods. However, existing pickup truck rear cargo pallets have insufficient load-bearing capacity, and the guide pulleys, bearing the weight of the objects and their inertia, are prone to rail deformation, easily causing jamming during pushing and pulling. A new pickup truck rear cargo sliding pallet architecture, a loading system specifically designed for pickup truck cargo beds, directly supports the weight of the cargo to the bottom of the rear cargo bed via bottom pulleys and guide rails. This improves load-bearing capacity, prevents rail deformation, ensures smoother pushing and pulling, and allows for flexible extension and retraction of the pallet, solving the pain point of inconvenient access to items deep within the traditional cargo bed. To address these issues, this application proposes a pickup truck rear cargo sliding pallet. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, this invention provides a sliding pallet for cargo storage in the rear trunk of a pickup truck, which features a simple structure, convenient operation, strong load-bearing capacity, and good stability.

[0006] Preferably, the sliding assembly includes a fixing frame, the fixing frame having a first sliding groove at the top and a second sliding groove at the bottom; A pulley is installed on the top of the support plate, and the pulley is embedded in the second groove and slides along its length. A pair of first convex sliders are slidably connected in the first groove, and the top of the first convex sliders passes through the first groove and is provided with a mounting plate.

[0007] Preferably, the moving component includes a roller guide rail, a third groove is provided on one side of the roller guide rail, a second convex slider is provided in the third groove, the second convex slider is locked to the fixing plate by bolts, and the fixing plate is fixed to the bottom of the rear trunk of the pickup truck by bolts, so that the roller guide rail can remain stationary during the movement of the pallet body; The other side of the roller guide rail is threaded with a plum blossom handle screw, one end of which passes through one side of the roller guide rail and is located inside the roller guide rail with a buffer block. The base frame is equipped with rollers at its bottom, and the rollers are in rolling cooperation with the roller guide rail.

[0008] Preferably, the locking component includes a handle disposed on the tray body; The base frame has a connecting plate at the bottom, and a reset spring indexing pin is installed on the connecting plate. The roller guide rail has multiple slots spaced apart on one side for the reset spring indexing pin to be inserted. The return spring indexing pin is connected to a pull wire, and the other end of the pull wire passes through the base frame and is connected to the handle.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example

[0018] Please see Figures 1-9 The present invention provides the following technical solution: a sliding pallet for storage in the rear trunk of a pickup truck, comprising a pallet body 1 and a base frame 2, wherein the base frame 2 is installed at the bottom of the pallet body 1, and support plates 3 are symmetrically fixedly connected to both sides of the pallet body 1; two sets of parallel sliding components are respectively installed on the top of the two support plates 3; two sets of moving components are symmetrically installed on the bottom two sides of the base frame 2; and a locking component is installed at the bottom of the base frame 2, which restricts the displacement of the pallet body 1 after it moves; the sliding components can be installed on the rear trunk of the pickup truck, driving the pallet body 1 to move back and forth relative to the rear trunk, facilitating the retrieval and placement of items from different positions in the trunk; the moving components assist the pallet body 1 in moving, which can improve the load-bearing capacity of the pallet body 1, while reducing friction during movement and improving operational convenience; when the pallet body 1 moves to the desired position, the locking components can lock the pallet body 1 to prevent displacement of the pallet body 1 and improve safety during use.

[0019] Preferably, by Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, in this embodiment, the sliding assembly includes a fixed frame 4, with a first sliding groove 8 at the top and a second sliding groove 9 at the bottom; a pulley 7 is installed on the top of the support plate 3, the pulley 7 is embedded in the second sliding groove 9 and slides along its length; a pair of first convex sliders 6 are slidably connected in the first sliding groove 8, the top of the first convex sliders 6 passes through the first sliding groove 8 and is provided with a mounting plate 5; during installation, the first convex sliders 6 are first installed below the mounting plate 5 by bolts, and the bottom end of the bolts passes through the first convex sliders 6 and abuts against the inner wall of the first sliding groove 8, thereby achieving a stable locking of the fixed frame 4; then the mounting plate 5 is fixed to the inner wall of the rear trunk of the pickup truck, thereby completing the connection between the sliding assembly and the rear trunk of the pickup truck. Through the sliding of the pulley 7 in the second sliding groove 9, combined with the sliding of the first convex sliders 6 in the first sliding groove 8, the tray body 1 can move back and forth smoothly and steadily in the rear trunk of the pickup truck, meeting the user's needs to take and put items from different positions in the trunk.

[0020] Preferably, by Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in this embodiment, the moving component includes a roller guide rail 16. A third groove 21 is provided on one side of the roller guide rail 16, and a second convex slider 20 is located within the third groove 21. The second convex slider 20 is locked to a fixing plate 19 by bolts. The fixing plate 19 is then fixed to the bottom of the pickup truck's rear trunk by bolts, allowing the roller guide rail 16 to remain stationary during the movement of the pallet body 1. A swivel handle screw 23 is threaded onto the other side of the roller guide rail 16. One end of the swivel handle screw 23 passes through the roller... A buffer block 24 is provided on one side of the roller guide rail 16 inside the roller guide rail 16; a roller 18 is installed at the bottom of the base frame 2, and the roller 18 rolls with the roller guide rail 16; during installation, the fixing plate 19 is first fixed to the rear trunk of the pickup truck with bolts, and then the second convex slider 20 is installed on the fixing plate 19 with bolts. Then, the roller guide rail 16 with the third groove 21 is fixed to multiple second convex sliders 20 with bolts, thereby fixing the roller guide rail 16 to the bottom of the rear trunk of the pickup truck. When it is necessary to adjust the position of the pallet for loading and unloading goods, simply pull the pallet body 1. The roller 18 will roll on the roller guide rail 16, thus moving the pallet body 1 in the rear of the pickup truck. When the roller 18 moves to the buffer block 24 that abuts against the outer wall of the plum blossom handle screw 23, the buffer block 24 can block the roller 18 and prevent it from continuing to move. The design utilizes the principle of the coordinated action of sliding and moving components: the sliding component provides sliding support for the top of the pallet body 1, and the moving component provides sliding support for the bottom of the pallet body 1. This dual-support structure design can effectively distribute the weight of the pallet body 1 and the goods it carries, significantly improving the overall load-bearing capacity. Even when heavy tools or materials are placed on it, it can maintain a stable sliding state. When the pallet body 1 is not in use, first unfasten the buckle 22, rotate the Phillips head handle screw 23 counterclockwise, remove the Phillips head handle screw 23 and the buffer block 24, and the pallet body 1 can be pulled out from the rear of the pickup truck for easy removal of the pallet body 1, thereby improving the convenience and flexibility of use.

[0021] Preferably, by Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in this embodiment, the locking component includes a handle 15 on the tray body 1; a connecting plate 10 is provided at the bottom of the base frame 2, and a return spring indexing pin 12 is installed on the connecting plate 10; a plurality of slots 17 are spaced apart on one side of the roller guide rail 16 for the return spring indexing pin 12 to be inserted; the return spring indexing pin 12 is connected to a pull wire 13, the other end of which passes through the base frame 2 and is connected to the handle 15; in use, when the tray body 1 moves to the target position and needs to be locked, the return spring indexing pin 12 pops out under its own spring force, and its end is precisely embedded in the slots 17 spaced apart on one side of the roller guide rail 16. The slots 17 limit the return spring indexing pin 12, thus restricting the tray body. The relative displacement between the pallet body 1 and the roller guide rail 16 achieves a stable lock, preventing the pallet body 1 from sliding freely and ensuring stable storage of goods. When it is necessary to move the pallet body 1, the handle 15 is pulled, and the handle 15 drives the return spring indexing pin 12 to retract against the spring force through the pull cable 13. Its end disengages from the slot 17, and the pallet body 1 and the roller guide rail 16 are no longer restricted, thus releasing the locked state. The pallet body 1 can then move flexibly again. This locking component design is simple and quick to operate, effectively fixing the position of the pallet body 1 and preventing it from sliding during transportation, thus improving stability and safety during use. At the same time, the use of the return spring indexing pin 12 makes the locking and unlocking process smoother.

[0022] Preferably, by Figure 4 , Figure 6 and Figure 8As shown, in this embodiment, the bottom of the connecting plate 10 is provided with a fisheye bolt 11 with a hole, and the pull wire 13 passes through the fisheye bolt 11 with a hole. This design enhances the connection stability between the pull wire 13 and the connecting plate 10, so that the pull wire 13 can pull the reset spring indexing pin 12 more stably when under force, avoiding the locking failure problem caused by the pull wire 13 loosening or falling off.

[0023] Preferably, by Figure 6 and Figure 8 As shown, in this embodiment, the bottom of the base frame 2 is provided with multiple pull cord clips 14, and the pull cord 13 is hung in the pull cord clips 14. This design allows the pull cord 13 to be properly fixed when not in use, avoiding interference or damage that may be caused by the pull cord 13 swinging randomly, and also facilitating the user's management and operation of the pull cord 13.

[0024] Preferably, by Figure 1 , Figure 2 , Figure 6 and Figure 9 As shown, in this embodiment, a buckle 22 is provided between the pallet body 1 and the fixing plate 19; when the pallet body 1 returns to its initial position, the buckle 22 can quickly fix the pallet body 1 to the fixing plate 19, preventing the pallet body 1 from accidentally sliding or shaking when not in use, and enhancing the stability of the pallet body 1 when stationary.

[0025] Preferably, by Figure 1 , Figure 2 , Figure 6 and Figure 9 As shown, in this embodiment, the plum blossom handle screw 23 is connected to the rubber buffer block 24 by threads. One end of the buffer block 24 is provided with a groove, and one end of the plum blossom handle screw 23 is fixed with a nut by threads. The nut is used to embed into the groove on the buffer block 24. This design allows the buffer block 24 to be moderately cushioned by the elasticity of the rubber material when it is squeezed by the roller 18, reducing the noise and vibration caused by hard collisions. At the same time, the structure of the nut embedding into the groove of the buffer block 24 enhances the connection stability between the plum blossom handle screw 23 and the buffer block 24, preventing loosening caused by long-term use or external force, and further improving the stability and safety of the tray body 1 during movement.

[0026] Components not described in detail in this article are existing technologies.

[0027] The working principle and usage process of this invention are as follows: During installation, the fixing plate 19 is fixed to the bottom of the rear cargo box of the pickup truck with bolts. The second convex slider 20 is installed on the fixing plate 19 with bolts. Then, the roller guide rail 16 with the third slide groove 21 is slidably connected to the second convex slider 20. The bolts on the second convex slider 20 are rotated to make it press against the inner wall of the third slide groove 21 to fix the position. The mounting plate 5 of the sliding component is fixed to the inner wall of the cargo box. The first convex slider 6 passes through the first slide groove 8 and is locked by bolts to ensure that the fixing frame 4 is firmly connected to the cargo box. At this time, the pallet body 1 is stored in the cargo box, the buckle 22 is fastened and fixed, the nut of the plum blossom handle screw 23 is located away from the center of the roller guide rail 16, and the reset spring indexing pin 12 is embedded in the slot 17 of the initial position, so that the whole remains stationary and stable. When loading and unloading goods, first unfasten the latch 22, then pull the handle 15. The pull cable 13 (guided by the fisheye bolt 11 and limited by the pull cable buckle 14) pulls the return spring indexing pin 12 to overcome the spring force and retract, disengaging it from the slot 17 and releasing the lock. At this time, pull the pallet body 1, and the pulley 7 of the sliding component slides along the second slide groove 9 of the fixing frame 4. When the pallet body 1 extends and carries a heavy load, the side support plates 3 will form a rigid support with the bottom of the second slide groove 9 of the fixing frame 4, effectively counteracting the tilting torque and preventing the pallet body 1 from tilting due to weight. When the load is generated, the front end tilts upward; the roller 18 of the moving component rolls along the raised roller guide 16. This raised structure allows the roller 18 to easily cross the groove between the tailgate and the bottom of the tail box and the height difference of the tailgate panel, avoiding jamming. The weight is distributed through the "double support" structure to ensure the smooth movement of the pallet; when the roller 18 abuts the buffer block 24 on the plum blossom handle screw 23, the pallet body 1 stops moving. After releasing the handle 15, the reset spring indexing pin 12 automatically springs into the corresponding slot 17 to lock the position, so that goods can be safely loaded and unloaded. After the goods are placed, pull the handle 15 again to unlock the indexing pin and push the pallet body 1 back to its original position: the roller 18 retracts along the roller guide rail 16 and the pulley 7 slides with the pallet body 1; after it is fully stored, release the handle 15 so that the indexing pin is inserted into the initial slot 17, and finally fasten the buckle 22 to ensure that the pallet body 1 does not move when the vehicle is in motion. If it is necessary to disassemble the tray body 1, first unfasten the buckle 22, rotate the Phillips head handle screw 23 counterclockwise, remove the Phillips head handle screw 23 and the buffer block 24, and then completely pull out the tray body 1; flexibly adaptable to scenarios where the tray body 1 is not needed; This design achieves convenience, stability, and flexibility in storing and retrieving cargo in the rear cargo box of pickup trucks through the coordinated support of sliding and moving components (including anti-tipping and obstacle crossing optimization), precise positioning of locking components, and a detachable structure, making it suitable for various load capacities and usage scenarios.
