[0002] A pickup truck has a roofless cargo box behind the cab. It is a light truck with cargo box side panels integrated with the cab. The trunk of a pickup truck is usually an undivided area. Users have increasingly diversified demands for the functions of the pickup truck trunk, which has led to an increasing demand for the installation of a trunk pallet. A trunk tray is a removable pallet tool used to facilitate the loading and unloading of goods in the truck trunk. Currently, the commonly used pallets are push-pull structures. The pallet is supported and guided by guide pulleys on the guide rails. The user pushes and pulls the pallet to adjust the relative position of the pallet for easy access to items. However, after the pallet is moved arbitrarily, the pallet is in a slidable state and is not relatively locked during the movement, causing the pallet to be able to slide at any time. Summary of the invention

[0017] (III) Beneficial effects

[0018] The fixed slide rail is used to slide with the sliding rail, and the guide roller installed on the sliding rail is limited to slide relative to the fixed slide rail without separation. At the same time, multiple guide pulleys are arranged on the connecting plate to support and guide the sliding rail and the load-bearing plate, so that the handle pulls the sliding rail to move relative to the fixed slide rail more flexibly, and the state of placing objects on the load-bearing plate can also slide flexibly;

[0019] At the same time, a damping frame is installed on the sliding rail to connect the damping wheel with an eccentric rotation, and a reset spring is used to drive the damping wheel to be in an original state so that the damping wheel contacts the fixed sliding rail and the sliding rail is stopped by friction. When the sliding rail needs to be moved, the damping wheel is pulled eccentrically relative to the damping frame by a pull rope pulled to the handle to break away from the state of contact with the fixed sliding rail. After the sliding rail moves to a specific position, the pull rope is released, and the reset spring continues to push the damping wheel to generate a contact friction force on the fixed sliding rail, thereby achieving locking at any sliding position of the sliding rail, and achieving stepless parking of the entire pallet at any position within the sliding stroke.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See also Figure 1 one Figure 7 As shown, in an embodiment of the present invention, a pickup truck trunk tray with stepless parking is proposed, comprising fixed slide rails arranged at intervals, connecting plates are installed at intervals on two fixed slide rails, a sliding rail is slidably installed on each of the fixed slide rails, a plurality of bearing plates laid in sequence along the length direction are embedded on the two sliding rails, the sliding rails are provided with guide rollers sliding relative to the fixed slide rails, a plurality of guide pulleys are installed at intervals on the connecting plates, and the sliding rails and the bearing plates both roll in cooperation with the guide pulleys; the fixed slide rails arranged at intervals are connected by connecting plates and the spacing distance is maintained, so that the bearing plates embedded and installed on the two sliding rails are more stable, and it is convenient to place items after the bearing plates are laid, and sliding slots can be opened on the bearing plates for pre-installing cable ties, ropes, etc. for tightening the items. The guide rollers arranged on the sliding rail form a limited sliding on the fixed sliding rail, so that the sliding rail will not be separated when sliding relative to the fixed sliding rail. At the same time, multiple guide pulleys arranged along the length direction of the connecting plate are used to support and guide the sliding of the load-bearing plate and the sliding rail, so that the sliding rail can slide stably relative to the fixed sliding rail under the load state, avoiding jamming after long-term use, and improving the convenience of use.

[0031] Since the sliding rail and the carrying plate constitute the main sliding parts in the tray, the sliding rail will be moved when the items are taken and placed, and it needs to be locked and stopped at any position after the movement, so as to avoid the risk of self-sliding when the items are taken and placed. Therefore, a damping frame is installed on at least one of the sliding rails, and at least one damping wheel is eccentrically mounted on the damping frame, and a pull rope is sleeved on the damping wheel, and a return spring for driving the damping wheel to reset is sleeved on the pull rope, and the damping wheel abuts against the fixed slide rail in a locked state. In the locked state, the damping wheel is always pushed to abut against the fixed slide rail by the action of the return spring to generate a friction force, so as to stop the sliding rail relative to the fixed slide rail; and when the sliding rail is slid to a relative position, the damping wheel is eccentrically rotated relative to the damping frame by the pull rope, so that the contact part is separated from the fixed slide rail, so that the sliding rail can move relative to the fixed slide rail, and after moving to any position, the pull rope is released, and the damping wheel is reset under the action of the return spring to continue to abut against the fixed slide rail for stopping.

[0032] By arranging the damping frame, damping wheel and pull rope on the sliding rail, the sliding rail can be docked at any position within the sliding stroke of the sliding rail relative to the fixed sliding rail, thereby achieving stepless docking, which is convenient for users to adjust the sliding distance of the sliding rail in various scenarios.

[0033] In order to facilitate the application of pushing and pulling forces to the sliding rails, handles are installed at the ends of the two sliding rails, and the sliding rails on both sides can be pulled or pushed at the same time through the handles, while also increasing the stability of the lateral connection of the load-bearing. The pull cord extends to the handle, which is convenient for synchronous pulling of the pull cord when holding the handle for operation, so as to achieve the same position operation; specifically, when the handle pushes and pulls the sliding rail relative to the fixed sliding rail, the pull cord is pulled to drive the damping wheel to rotate eccentrically to separate relative to the fixed sliding rail, so that the pull cord and the handle are held for pulling or pushing, and the pull cord can be pulled by the hand of the user.

[0034] Among them, the eccentric rotation angle of the damping wheel relative to the damping frame only needs to be separated from the fixed slide rail. Therefore, the distance that the pull rope actually needs to be pulled is relatively small. It can be integrated on the handle and the pull rope can be pulled synchronously to move a certain distance when held by hand.

[0035] In order to facilitate the locking and stopping effect, the number of the damping wheels is two, and the two damping wheels are symmetrically mounted on the damping frame. The two ends of the reset spring are respectively abutted against the two damping wheels. By pulling the two symmetrically arranged damping wheels eccentrically through a pull rope, they can be synchronously rotated and separated relative to the fixed slide rail. After releasing the pull rope, the reset spring pushes the two damping wheels to reset and rotate respectively, and at the same time abut against the fixed slide rail.

[0036] Among them, the damping wheel is provided with a rotating hole eccentrically arranged relative to the center, and the damping wheel is provided with a chamfered structure at the corner on one side of the fixed slide rail. The damping wheel is installed on the damping frame by rotating through the rotating hole eccentrically arranged relative to the center of the damping wheel. At the same time, the chamfered structure is provided on one side. The chamfered structure can be arranged on the side of the direction of eccentric rotation of the damping wheel when the pull rope is pulled, so as to facilitate faster separation relative to the fixed slide rail, and the other side can quickly resist the fixed slide rail when resetting.

[0037] The sliding rail and the carrying plate need to be locked after being pushed back, and they need to be quickly unlocked when pulled. Specifically, limit blocks are fixed at both ends of the connecting plate on one side of the handle, and an elastic hook assembly is installed on the handle. When the handle moves with the elastic hook assembly, it can be separated or locked relative to the limit block. When the handle moves with the elastic hook assembly, it can be separated or locked relative to the limit block. The elastic hook assembly has an elastic deformation effect. When the handle pulls the sliding rail to move relative to the fixed rail and takes and places items, the elastic hook assembly is relatively The limit block is deformed until it leaves the limit state of the limit block and is unlocked. At this time, the sliding rail can be freely pulled to move relative to it. When the sliding rail needs to be reset and locked, the sliding rail is pushed inward by the handle, so that the elastic hook assembly is deformed relative to the limit block until it passes the limit block and is reset, and cooperates with the limit block to achieve limit locking. After applying a pulling force or a pushing force, the deformation of the elastic hook assembly is used to achieve switching between unlocking and limit locking states, thereby avoiding the use of additional tools for operation and improving ease of use.

[0038] Among them, the elastic hook assembly includes a first elastic rod installed on the handle for sliding at intervals, a second elastic rod is vertically fixed on the two first elastic rods, and the two ends of the second elastic rod are rotatably installed with limit hooks respectively, a positioning plate is fixed on the handle, the limit hook is rotatably installed on the positioning plate, and a torsion spring is also installed on the positioning plate, and the elastic arm of the torsion spring is connected to the part of the limit hook that deviates from the rotation axis; when the entire elastic hook assembly is pulled and deformed relative to the handle, the limiting part on the limit hook passes over the limiting block mainly through the sliding of the first elastic rod relative to the handle and the relative bending deformation of the second elastic rod, and after the limiting part completely passes over the limiting block, 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 reset.

[0039] Specifically, a guide slide is provided on the fixed slide rail, and the slide rail includes a sliding portion extending into the guide slide, the sliding portion and the slide rail form an I-shaped structure, and guide rollers are installed on the sliding portion at intervals, and the guide rollers are limited to roll in the guide slide, and the portion of the slide rail located on one side of the guide slide is in rolling cooperation with the guide pulley; by sliding the guide pulley into the guide slide to form a limit, there is no risk of separation during the sliding process of the slide rail relative to the slide rail, and the guide roller is used as the main bearing part, and the guide pulley is used to guide the slide and further support the slide rail, thereby simultaneously improving the bearing strength at two sliding positions and meeting the stable sliding under the bearing condition. At the same time, a first deviation correction bearing is also provided on the sliding portion, which is located on both sides of the guide roller, and the first deviation correction bearing is also in rolling cooperation with the guide slide, and the rotation direction of the first deviation correction bearing is vertical to the rotation direction of the guide roller in space, and the first deviation correction bearing is used to ensure that the slide rail can avoid swinging left and right during the sliding process, thereby ensuring stable opening and closing.

[0040] In order to further guide the sliding rail to slide outside the guide slideway and correct the deviation, a second correcting bearing is installed at the end of the fixed slide rail, and the second correcting bearing is in rolling cooperation with the sliding rail.

[0041] Correspondingly, an opening is provided on the guide slide, and the first correcting bearing rolls with the opening to meet the correcting guide requirements. At the same time, the width of the guide roller is larger than the width of the opening to ensure that the sliding rail will not detach from the guide slide.

[0042] Specifically, the guide pulley includes a mounting bracket installed on the connecting plate, and a plurality of rotating wheels are rotatably mounted on the mounting bracket. A module structure is formed by installing the plurality of rotating wheels through the mounting bracket. The sliding rail and the load-bearing plate can be slidably supported as needed, and the guide pulley is installed on the fixed slide rail accordingly. In this embodiment, at least 3 groups are evenly distributed along the length direction of the connecting plate, thereby forming a load-bearing state with uniform force.

[0043] During the relative sliding process, the sliding rail has a movement limit position, and an impact sound may be generated when sliding to the limit position. A baffle is fixed at one end of the two fixed sliding rails away from the handle, and a damping pad is installed on the baffle, which extends into the guide slide and is used to cushion the impact of the sliding part. The damping pad is used to form an impact buffer for the sliding part to avoid noise, and at the same time protect the sliding rail when it moves to a closed state.
