Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to a pull-out sliding tray for the rear bed of a pickup truck. Background Technology

[0002] With the widespread use of pickup trucks in logistics transportation, outdoor operations and other fields, the demand for cargo management in the truck bed is increasing. In order to improve cargo loading and unloading efficiency and ease of access, a variety of pull-out pallet products have emerged in the market to improve the space utilization and operational convenience of pickup truck beds.

[0003] Existing pickup truck bed pull-out pallets typically consist of a pallet body and a sliding mechanism. First, the pallet body is mostly a support plate lacking a limiting structure. After goods are placed on the pallet body, the lack of limiting structure makes it easy for the goods to slide and shift during vehicle movement. Second, the pallet body uses traditional sliding rails or guide rails to move the pallet back and forth in the truck bed, which is complex, costly to manufacture, space-consuming, and inconvenient to install and maintain. Finally, the pallet body is mostly a fixed-size integral design, which cannot be adjusted according to the length of the truck bed of different pickup truck models, resulting in poor versatility and increased production and inventory costs. Summary of the Invention

[0004] This invention proposes a pull-out sliding pallet for pickup truck beds to solve the technical problems mentioned in the background art, such as easy slippage and displacement of goods, unsmooth pulling, and inability to adapt to different vehicle models.

[0005] The technical solution of this invention is implemented as follows: A pull-out sliding tray for a pickup truck bed, comprising: The pallet body, which is used to carry goods and is set on the bottom of the truck bed; A sliding mechanism is provided at the bottom of the pallet body for the pallet body to slide relative to the bottom surface of the truck bed; Multiple raised positioning structures are disposed on the upper surface of the tray body and arranged in a regular array; At least one positioning block is detachably disposed on the upper surface of the tray body; The bottom of the positioning block has at least one opening, the shape of which matches the raised positioning structure, so that the positioning block can be detachably engaged with the raised positioning structure by plugging in, thereby limiting and fixing the goods placed on the pallet body.

[0006] Preferably, the pallet body is composed of multiple detachable and interlocking panels, and the number of interlocking panels can be adjusted according to the size of the truck bed to accommodate truck beds of different lengths.

[0007] Preferably, the positioning block has a T-shaped or L-shaped structure, including a crossbeam and a vertical arm.

[0008] Preferably, the openings are provided on both the crossbeam and the vertical arm.

[0010] Preferably, the protrusion positioning structure further includes multiple cross-shaped protrusions, which are disposed in the gaps between adjacent capsule-shaped protrusions to form an anti-slip support array.

[0011] Preferably, the top of the positioning block is provided with a protruding stacking structure that matches the opening, so as to realize the stacking and installation of multiple positioning blocks in the vertical direction.

[0012] Preferably, the sliding mechanism includes a plurality of rollers, which are respectively disposed on both sides of the bottom of the tray body.

[0013] Preferably, both the crossbeam and the vertical arm are provided with mounting notches, and the size of the mounting notches is larger than the outer dimensions of the protruding positioning structure.

[0014] Preferably, a reinforcing partition is provided at the bottom of the splicing point of two adjacent splicing panels. The reinforcing partition has a plate-like structure and is fastened to the adjacent splicing panels on both sides.

[0015] By adopting the above technical solution, the beneficial effects of the present invention are as follows: (1) The present invention achieves flexible fixation of goods at multiple points on the pallet by combining the raised positioning structure with the plug-in positioning block. At the same time, the positioning block can be plugged into any position of the array of raised positioning structure, which can adapt to the fixing requirements of goods of different sizes, effectively prevent the goods from sliding and displacing during the journey, and improve transportation safety. (2) The present invention uses rollers instead of traditional slide rails or guide rails, which simplifies the pull-out mechanism, reduces manufacturing costs and space occupation, makes the pull-out operation of the pallet smoother and more convenient, and improves the user experience. (3) The pallet body of the present invention adopts a splicing modular structure, which can be adapted to different length pickup truck models by adjusting the number of splicing plates, thereby improving the versatility of the product, reducing production and inventory costs, and expanding the market application scope; (4) The present invention provides a reinforcing partition at the bottom of the splice, which significantly enhances the structural strength of the splice, making the pallet less prone to breakage or deformation when bearing heavy loads, extending its service life and improving safety.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] See Figure 1-15 A pull-out sliding pallet for a pickup truck bed includes a pallet body 1, a sliding mechanism 2, a raised positioning structure 3, and a positioning block 4. The sliding mechanism 2 is used to slide the pallet body 1 relative to the bottom of the truck bed. The raised positioning structure 3 is disposed on the upper surface of the pallet body 1 and is arranged in a regular array. The positioning block 4 is detachably disposed on the upper surface of the pallet body 1. The bottom of the positioning block 4 is provided with an opening 401 whose shape matches that of the raised positioning structure 3. The positioning block 4 is positioned and fixed by interlocking with the raised positioning structure 3 through the opening 401.

[0021] In some embodiments, such as Figure 5 and 6 As shown, the goods are placed on the raised positioning structure 3 on the upper surface of the pallet body 1. The raised positioning structure 3 provides support for the goods and also provides friction for them. Then, the positioning block 4 is inserted and fixed to the raised positioning structure 3 through the opening 401. The positioning block 4 is arranged around the perimeter of the goods. Multiple positioning blocks 4 can be combined to form a barrier structure, which restricts the movement of the goods from multiple directions and ensures that the goods are stably fixed on the pallet body 1. At this time, the positioning block 4 can further restrict the movement of the goods on the pallet body 1, so that the goods are firmly fixed.

[0022] In some embodiments, the protrusion positioning structure 3 includes a cross-shaped protrusion 301 and a capsule-shaped protrusion 302, which are arranged alternately. Specifically, the capsule-shaped protrusions 302 are arranged alternately in the horizontal and vertical directions, and the cross-shaped protrusions 301 are disposed in the gap between adjacent capsule-shaped protrusions 302. The cross-shaped protrusions 301 and capsule-shaped protrusions 302 are arranged in a regular array on the upper surface of the tray body 1 to form a high-density protrusion array. This array layout provides multiple insertion anchor points for the positioning block 4, so that the positioning block 4 can be inserted and fixed at any position on the upper surface of the tray body 1. The cross-shaped protrusion 301 has four rounded corners. The rounded corner design not only ensures a good fit with the opening 401, but also avoids stress concentration caused by sharp corners, thus improving the durability of the protrusion positioning structure 3.

[0023] In some embodiments, the positioning block 4 has a T-shaped structure. The positioning block 4 includes a crossbeam 402 and a vertical arm 403. The vertical arm 403 extends vertically downward from the middle of the crossbeam 402 and is fixedly connected to the crossbeam 402 to form a T-shaped overall structure. The T-shaped crossbeam 402 provides a larger contact area for the goods, enhancing the limiting effect on the goods, while the vertical arm 403 provides sufficient structural strength. Both the crossbeam 402 and the vertical arm 403 adopt a hollow wall panel structure to form an opening 401, and the shape of the opening 401 includes a cross star shape and a capsule shape, which allows the crossbeam 402 and the vertical arm 403 to be assembled and disassembled on the cross star-shaped protrusion 301 and the capsule-shaped protrusion 302. Specifically, align the opening 401 of the positioning block 4 with the cross-shaped protrusion 301 or capsule-shaped protrusion 302 on the upper surface of the tray body 1, and press the positioning block 4 downward so that the opening 401 fits onto the protruding positioning structure 3. Through the shape matching between the opening 401 and the protruding positioning structure 3, the positioning block 4 is fixed on the upper surface of the tray body 1. Since the protruding positioning structure 3 is arranged in a regular array, the positioning block 4 can be inserted at any protruding position on the upper surface of the tray body 1, realizing flexible adjustment of the positioning position.

[0024] Because the internal structure of the positioning block 4 is a hollow wall panel, the weight is reduced while ensuring the strength of the positioning block 4, thus achieving lightweighting. The two ends of the crossbeam 402 are rounded rectangular columns. The rounded rectangular column design increases the contact area with the goods, avoids damage to the surface of the goods by sharp corners, and improves the structural strength of the positioning block 4.

[0025] In some embodiments, such as Figure 3As shown, both the crossbeam 402 and the vertical arm 403 are provided with mounting notches 405. The size of the mounting notches 405 is larger than the outer dimensions of the protrusion positioning structure 3. After the crossbeam 402 and the vertical arm 403 are inserted into the cross-shaped protrusion 301 and the capsule-shaped protrusion 302, the notches 405 can accommodate the similar cross-shaped protrusion 301 and capsule-shaped protrusion 302, so that the bottom of the positioning block 4 is in contact with the upper surface of the tray body 1, maintaining the stability of the positioning block 4.

[0026] In other embodiments, the positioning block 4 has an L-shaped structure. The positioning block 4 adopts a hollow wall panel structure to form an opening 401. The shape of the opening 401 includes a cross-shaped shape and a capsule shape, which allows the crossbeam 402 and the vertical arm 403 to be assembled and disassembled on the cross-shaped protrusion 301 and the capsule-shaped protrusion 302. The L-shaped structure is particularly suitable for fixing the corners of goods. It can simultaneously fix both sides of the corner of the goods, thus providing stronger support at the corners and effectively preventing the goods from tipping over.

[0027] In other embodiments, the top of the positioning block 4 is provided with a protruding stacking structure 404 adapted to the opening 401, so that multiple positioning blocks 4 can be stacked vertically (e.g., Figure 15 The diagram shown illustrates the stacking of two positioning blocks 4. When dealing with goods of different heights, especially taller goods, the height of a single positioning block 4 is insufficient, resulting in poor support and limiting effect. In this case, the positioning blocks 4 are stacked together by the protruding stacking structure 404, which increases the total support height. This makes the goods more securely limited. The number of positioning blocks 4 stacked depends on the height of the goods.

[0028] In some embodiments, the sliding mechanism 2 includes rollers disposed at the bottom of the pallet body 1. Under the action of the rollers, the pallet body 1 can move relative to the truck bed, making it easier for the pallet body 1 to enter and exit the truck bed, thereby facilitating the entry and exit of goods from the truck bed. Multiple rollers are provided, which are located on both sides of the bottom of the pallet body 1, and the multiple rollers are divided into two groups and symmetrically distributed along the long side of the pallet body 1. Specifically, the rollers are fixedly connected to the bottom surface of the pallet body 1 through bearing seats or brackets. The wheel body of the rollers extends downward so that the outer circumference of the rollers contacts the bottom surface of the truck bed. Multiple rollers are arranged in pairs along the long side of the pallet body 1. Several pairs of rollers are set on each side of the pallet body 1 to form a balanced support layout. The rollers make rolling contact with the bottom surface of the truck bed. When a pushing or pulling force is applied to the pallet body 1, the rollers roll on the bottom surface of the truck bed, causing the pallet body 1 to slide relative to the bottom surface of the truck bed in the front-back direction, thereby realizing the pull-out function of the pallet body 1. By using rollers instead of traditional slide rails or guide rails, the pull-out mechanism is simplified, manufacturing costs and space occupation are reduced, and the pull-out operation of the pallet body 1 is smoother and more convenient.

[0029] In some embodiments, the pallet body 1 is composed of at least two splicing panels 101, and a reinforcing partition 6 (such as...) is provided at the bottom of the splicing joint between two adjacent splicing panels 101. Figure 14 As shown), the reinforcing partition 6 has a plate-like structure and is fixedly connected to the bottom of two adjacent splicing panels 101; Specifically, the length of the reinforcing partition 6 is perpendicular to the splice seam. The reinforcing partition 6 is fixedly connected to the bottom of two adjacent splice plates 101 and spans across both sides of the splice seam. The reinforcing partition 6 is fixedly connected to the bottom surface of the two adjacent splice plates 101 by means of bolts, welding or gluing, etc., which firmly connects the two adjacent splice plates 101 together, significantly enhancing the structural strength of the splice and preventing the pallet body 1 from breaking or deforming at the splice when bearing heavy objects.

[0030] The number of splicing panels 101 can be adjusted when dealing with different vehicle models, so that pallet bodies 1 of different lengths can be assembled to fit different vehicle models.

[0031] In some embodiments, such as Figure 2 and Figure 5 As shown, the periphery of the splicing panel 101 is provided with an edge frame 1011, and the edge frame 1011 is provided with a plurality of fastening holes 10111. The fastening holes 10111 are used to install fasteners so that two adjacent splicing panels 101 are assembled and fixed. Specifically, the pallet body 1 is composed of at least two splicing panels 101. The two adjacent splicing panels 101 are connected end to end in the length direction of the pallet body 1. The fastening holes 10111 opened on the edge frames 1011 of the two adjacent splicing panels 101 are corresponding and connected, and are fixed by fasteners. The two adjacent splicing panels 101 are spliced ​​together by a fixed connection to form a complete pallet body 1.

[0032] In some embodiments, fasteners include, but are not limited to, bolts.

[0033] In some embodiments, a plurality of rollers are disposed on both sides of the periphery of the edge frame 1011, and the plurality of rollers are divided into two groups and symmetrically distributed along the long side of the edge frame 1011. Specifically, the roller is fixedly connected to the inside of the edge frame 1011 via a bearing housing or bracket (e.g., Figure 5 As shown), the wheel body of the roller extends downward, so that the outer circumference of the roller contacts the bottom surface of the truck bed, and there is a gap between the splicing plate 101 and the bottom surface of the truck bed so that they do not contact each other. Multiple rollers are arranged in pairs along the long side of the edge frame 1011.

[0034] The pallet body 1 is also equipped with a limiting mechanism 5 to restrict the movement of the pallet body 1 in the truck bed. Under the action of the limiting mechanism 5, the pallet body 1 can be prevented from sliding, so that the pallet body 1 and the goods on the pallet body 1 are stably placed in the truck bed.

[0035] In some embodiments, the limiting mechanism 5 is disposed on the edge frame 1011 of a splicing plate 101 near the tailgate of the tray body 1, and there are two limiting mechanisms 5, which are symmetrically disposed on the short side of the edge frame 1011. The limiting mechanism 5 includes a threaded rod 501 threadedly mounted on the edge frame 1011, a limiting block 502 fixedly mounted on the bottom of the threaded rod 501, and a toggle block 503 fixedly mounted on the top of the threaded rod 501. When placing goods, open the tail door of the truck bed, pull the pallet body 1 to slide the pallet body 1 out of the truck bed, place the goods on the upper surface of the raised positioning structure 3 of the pallet body 1. The raised positioning structure 3 can provide friction for the goods and initially limit the goods. Then, the positioning block 4 is inserted into the raised positioning structure 3 through the opening 401 to fix it. When the goods are placed on the positioning block 4, the positioning block 4 is set around the goods. At this time, under the action of the positioning block 4, the movement of the goods on the pallet body 1 can be further restricted, so that the goods are fixed firmly. Then push the pallet body 1 to enter the truck bed. After the pallet body 1 is fully inserted into the truck bed, the threaded rod 501 is threadedly installed with the edge frame 1011. The user holds the toggle block 503 and rotates the threaded rod 501 clockwise. During the rotation, the threaded rod 501 can drive the limit block 502 to move downward until the bottom of the limit block 502 can contact the bottom surface of the truck bed. At this time, the limit block 502 can prevent the rollers from slipping. Then the tailgate is closed.

[0036] In some embodiments, to prevent the threaded rod 501 from rotating due to vibrations during vehicle operation, positioning holes are provided on the short sides of both the actuating block 503 and the edge frame 1011. When the limiting block 502 contacts the bottom surface of the truck bed, the positioning holes in the actuating block 503 correspond to the positioning holes on the short sides of the edge frame 1011. The positioning pin 506 is inserted from top to bottom into the positioning holes in the actuating block 503 and the edge frame 1011, which can prevent the actuating block 503 from rotating, thereby preventing the threaded rod 501 from rotating due to vibration, and allowing the limiting block 502 to contact the bottom surface of the truck bed.

[0037] In some other embodiments, a limiting mechanism 5 is provided, which is located on the short side of the edge frame 1011. The limiting mechanism 5 includes a threaded rod 501 threadedly mounted on the edge frame 1011, a limiting plate 504 rotatably mounted on the bottom of the threaded rod 501, a toggle block 503 fixedly mounted on the top of the threaded rod 501, and a guide rod 505 fixedly mounted on the edge frame 1011. The limiting plate 504 has a guide hole that cooperates with the guide rod 505. The limiting plate 504 is slidably sleeved on the guide rod 505 through the guide hole. The length of the guide rod 505 leaves a gap with the diameter of the bottom surface of the truck bed, and the length of the guide rod 505 is greater than the maximum downward displacement of the limiting plate 504. This arrangement can prevent the limiting plate 504 from disengaging from the guide rod 505. Since the threaded rod 501 is threadedly installed with the edge frame 1011, the user holds the toggle block 503 and rotates the threaded rod 501 clockwise. During the rotation, the threaded rod 501 can drive the limiting plate 504 to move downward until the bottom of the limiting plate 504 can contact the bottom surface of the truck bed. At this time, the limiting plate 504 can prevent the roller from slipping. Then the tailgate is closed. In this embodiment, only the toggle block 503 needs to be toggled once, making the operation more convenient.

[0038] In other embodiments, the positioning holes on the short sides of both the actuating block 503 and the edge frame 1011 are threaded, and the positioning pin 506 is also threaded. When the positioning pin 506 is screwed into the positioning holes on the actuating block 503 and the edge frame 1011, the positioning pin 506 can be fixed by the threaded engagement, thereby limiting the actuating block 503 and preventing the actuating block 503 and the threaded rod 501 from rotating.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
