Description

Technical Field

[0001] This utility model relates to the field of pickup truck tail tray technology, and in particular to a pickup truck tail tray. Background Technology

[0002] Pickup trucks typically feature an open-top cargo bed behind the cab, making it a light-duty truck with the cargo bed side panels integrated with the cab. The rear cargo bed of a pickup truck is usually an undivided area. As user needs for the functionality of the pickup truck rear cargo bed become increasingly diverse, the demand for cargo bed pallets is growing. A cargo bed pallet is a detachable pallet tool used to facilitate loading and unloading of goods from the rear cargo bed of a pickup truck. Currently, the most common pallet type is a push-pull structure. Guide pulleys on guide rails support and guide the pallet's movement. When pushing the pallet back to its original position, it needs to be locked to prevent the risk of uncontrolled sliding. Existing technologies primarily use keys or manual rotation to lock the pallet, requiring manual operation for locking or unlocking. If these tools are lost, locking or unlocking the pallet becomes difficult, resulting in poor convenience. Utility Model Content

[0004] The purpose of this utility model is to provide a pickup truck tailgate tray, which solves the problem in the prior art that tools are needed to manually operate the locking or unlocking state of the tray.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pickup truck tailgate tray includes a spaced-apart slide rail system. The slide rail system includes fixed slide rails and slide rails that slide relative to the fixed slide rails. Multiple support plates are embedded in the two slide rails and laid sequentially along their length. A connecting plate is installed between the two fixed slide rails and spaced along their length. Multiple guide pulleys are spaced apart on the connecting plate, and the slide rails and the support plates are in rolling cooperation with the guide pulleys. Pull blocks are installed at the ends of the two slide rails. Elastic hook assemblies are installed on the pull blocks.

[0010] Preferably, a second correction bearing is installed at the end of the fixed slide rail, and the second correction bearing is in rolling engagement with the slide rail.

[0011] Preferably, the guide slide has an opening, and the first correction bearing rolls into the opening: the width of the guide roller is greater than the width of the opening.

[0012] Preferably, the guide pulley includes a mounting bracket mounted on the connecting plate, and a plurality of rotating wheels are rotatably mounted on the mounting bracket.

[0016] By installing a pull block at the end of the sliding rail, and then mounting the elastic hook assembly on the pull block, the sliding rail moves relative to the fixed sliding rail when the pull block moves, thus facilitating the loading and unloading of items on the carrying plate. When the sliding rail is pulled outward, the elastic hook assembly deforms relative to the limiting block until it disengages from the limiting block, thus unlocking. When the sliding rail is pushed inward to reset, the elastic hook assembly deforms relative to the limiting block until it engages with the limiting block and then resets, forming a limit stop with the limiting block to prevent the sliding rail from sliding outward.

[0017] Therefore, by simply applying tension or thrust to the sliding rail, the elastic deformation of the elastic hook assembly, in conjunction with the limiting block, can achieve unlocking or locking, avoiding the need for additional tools. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] See Figures 1-6 As shown in the embodiment of this utility model, a pickup truck tail tray is proposed, including a slide rail system arranged at intervals. The slide rail system includes fixed slide rails and slide rails that slide relative to the fixed slide rails. The slide rails slide relative to the fixed slide rails to facilitate the push-pull adjustment of the tray. Specifically, multiple support plates are embedded in the two slide rails and laid sequentially along their length. After laying multiple support plates, there is a part for placing items. Thus, in order to facilitate the loading and unloading of items on the support plates, the slide rails can be moved by pushing and pulling. Specifically, a connecting plate is installed between the two fixed slide rails and arranged at intervals along their length. Multiple guide pulleys are spaced apart on the connecting plate. The slide rails and the support plates are all in rolling cooperation with the guide pulleys. The connecting plate relatively fixes the two spaced fixed slide rails and maintains stable sliding. The multiple guide pulleys support the slide rails and support plates during the sliding process and further improve the sliding flexibility and reduce the friction under load.

[0028] Because of the relative sliding characteristic and the potential for automatic slippage when installed on a pickup truck, a locking mechanism is needed to prevent slippage during movement. Specifically, pull blocks are installed at the ends of two sliding rails. Each pull block is equipped with an elastic hook assembly. Limit blocks are fixed to both ends of a connecting plate located on one side of the pull block. When the pull block moves with the elastic hook assembly, it can separate from or lock relative to the limit blocks. Utilizing the elastic deformation of the elastic hook assembly, when the pull block pulls the sliding rail relative to the fixed rail for loading and unloading items, the elasticity... The hook assembly deforms relative to the limiting block until it disengages from the limiting block, thus unlocking the slide rail. At this point, the slide rail can be freely pulled to move relative to it. When it is necessary to reset and lock the slide rail, the sliding rail is pushed inward by pulling the block, causing the elastic hook assembly to deform relative to the limiting block until it engages with the limiting block and resets. It then cooperates with the limiting block to achieve a limiting lock. Thus, by applying pulling or pushing force, the deformation of the elastic hook assembly can be used to switch between unlocking and limiting lock states, avoiding the need for additional tools and improving ease of use.

[0029] The elastic hook assembly includes first elastic rods slidably mounted on the pull block at intervals, and second elastic rods vertically fixed on the two first elastic rods. Limit hooks are rotatably mounted on both ends of the second elastic rods. A positioning plate is fixed on the pull block, and the limit hooks are rotatably mounted on the positioning plate. A torsion spring is also mounted on the positioning plate, and the elastic arm of the torsion spring is connected to a part of the limit hook that is off-axis of rotation. When the entire elastic hook assembly is pulled and deforms relative to the pull block, the first elastic rods slide relative to the pull block, and the second elastic rods bend and deform relative to the pull block, causing the limiting part of the limit hook to engage in the slot of the limiting block. After the limiting part engages in the slot, the elastic force of the torsion spring is used to reset the rotation angle of the limit hook, so that the entire elastic hook assembly is in a limited state.

[0030] Specifically, a guide rail is provided on the fixed slide rail. The slide rail includes a sliding part extending into the guide rail, forming an I-shaped structure with the slide rail. Guide rollers are installed at intervals on the sliding part, and the guide rollers are limited to rolling within the guide rail. The portion of the slide rail located on one side of the guide rail rolls in cooperation with the guide rollers. By sliding the guide rollers into the guide rail to form a limit, the slide rail will not be at risk of detachment during sliding relative to the slide rail. Furthermore, the guide rollers serve as the main load-bearing component, guiding and supporting the slide rail, thereby simultaneously increasing the load-bearing strength at both sliding positions and ensuring stable sliding under load conditions. Simultaneously, a first correction bearing is provided on the sliding part on both sides of the guide roller. The first correction bearing also rolls in cooperation with the guide rail, and its rotation direction is spatially perpendicular to the rotation direction of the guide roller. The first correction bearing ensures that the slide rail avoids lateral swaying during sliding, thus ensuring stable opening and closing.

[0031] In order to further guide and correct the sliding rail outside the guide rail, a second correction bearing is installed at the end of the fixed sliding rail, and the second correction bearing is in rolling engagement with the sliding rail.

[0032] Correspondingly, an opening is provided in the guide slide, and the first correcting bearing rolls into the opening to satisfy the correcting guidance. Simultaneously, the width of the guide roller is greater than the width of the opening to ensure that the sliding rail does not detach from the guide slide. Specifically, the guide pulley includes a mounting bracket mounted on the connecting plate. Multiple rotating wheels are rotatably mounted on the mounting bracket. After the multiple rotating wheels are mounted on the mounting bracket, a modular structure is formed. The sliding support position of the sliding rail and the bearing plate can be adjusted as needed. Correspondingly, guide pulleys are installed on the fixed slide rail. In this embodiment, at least three sets are evenly distributed along the length of the connecting plate to form a uniformly applied load-bearing state.

[0033] Specifically, the fixed slide rail includes a mounting base, the guide slide is integrated on the mounting base, a first connecting groove located on one side of the guide pulley and a second connecting groove on the side away from the guide pulley are provided between the mounting base and the guide slide, and a third connecting groove with an outward opening is also provided on the side of the second connecting groove, and the bearing plate is installed in the third connecting groove; the mounting base is used to install and fix the entire fixed slide rail, and the first and second connecting grooves on the outside of the guide slide can realize the connection method expansion in the extension direction, such as setting a locking thread hole structure in the first and second connecting grooves to realize the installation connection expansion structure, while the third connecting groove can be used to connect two adjacent fixed slide rails, or to install and fix the fixed slide rail from the side.

[0034] The sliding rail includes a sliding recess that mates with the guide rail. One side of the sliding recess has a support portion that rolls with the guide pulley. The sliding portion is located within the sliding recess, and the other side has a connecting portion. The sliding recess avoids the guide rail and integrates the sliding portion into the guide rail. The integrally formed support portion supports the guide pulley, ensuring the entire sliding rail remains balanced under load. The connecting portion is used for extended connections. The support portion has a laterally extending mounting groove, and a through fourth connecting groove. The connecting portion has an upwardly communicating fifth connecting groove and a through sixth connecting groove. The pulling block is installed in the fourth and sixth connecting grooves via connectors, such as using a screw as a connector to fix the pulling block. The fifth connecting groove facilitates the limiting installation of structures requiring bolting at the top. For example, when securing items placed on a tray with straps, a bolting block can be pre-installed in the fifth connecting groove.

[0035] Therefore, by optimizing the cross-sectional structure of the fixed slide rail and the sliding rail, the connection can be expanded, and the structural strength can be guaranteed after integral molding.
