Description
Technical Field
[0001] This utility model belongs to the field of automotive technology and relates to a pickup truck bed expansion box. Background Technology
[0002] A pickup truck is a vehicle type that uses a car-like front end and cab, while also having an open cargo bed. Once the requirements for comfort and practicality are met, owners are starting to pay attention to modifications that allow for a more enclosed cargo bed.
[0003] To address this issue, a multi-functional expandable box for pickup truck beds was designed and a Chinese patent was applied for, with application number 202223119930.8 and publication number CN218703547U. This multi-functional expandable box includes an open-bottomed body with a connector at the bottom. The sides of the body have several vertically arranged, openable and closable doors. A horizontally fixed, plate-like partition is located inside the box, with one end of the partition adjacent to one of the doors, and the upper side of the partition not exceeding the lower edge of the door. This expandable box can be fixed to the top of the pickup truck bed to enclose the bed, facilitating storage of items in the pickup truck bed.
[0004] When outdoors, tables are often needed to place items on them. Folding tables are often chosen for easy storage because they are low in height and take up little space. However, the aforementioned extension box creates a closed space in the pickup truck bed, causing tables and other items to fall into the bed. This means the table is lower than the sliding door, making it inconvenient to retrieve and use. Utility Model Content
[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a pickup truck bed extension box, which solves the problem that it is inconvenient to use a table after the existing extension box is installed in the pickup truck bed.
[0006] The objective of this utility model can be achieved through the following technical solutions: A pickup truck bed expansion box includes an open-bottomed box body with an opening through one side. A sliding door connected to the box body controls the opening and closing of the opening. The expansion box further includes a bracket fixed to the box body, two long rod-shaped connecting rods, a square-shaped table, and two rope-shaped fasteners. The bracket has two straight grooves, parallel to each other and spaced horizontally. The two connecting rods are parallel, with one end slidably connected to the two grooves of the bracket. When the two connecting rods slide along the grooves, their other ends protrude through the opening. The two sides of one end of the table are hinged to the other ends of the two connecting rods, allowing the table to rotate vertically relative to the connecting rods. One end of each of the two fasteners is fixed to the other two sides of the table. The box body also has two fixing parts positioned higher than the bottom of the opening, and the other ends of the two fasteners are detachably connected to these fixing parts.
[0007] When the table is not in use, the fasteners can be removed from the fixed part of the pickup truck bed. Push the connecting rod and table into the bed along the slide groove until they retract into the bed. Close the door to store the table. When needed, open the door and pull the table outwards. The connecting rod slides outwards along the slide groove until the other end of the connecting rod and the table protrude from the bed. Flip the table up and down to a horizontal position, and secure it to the fixed part. One side of the table is then connected to the support via the connecting rod, and the other side is secured to the fixed part of the bed via two fasteners, providing four-point support for the table and keeping it in place for use. In this way, the table is directly integrated into the bed, allowing it to be easily moved in and out without having to reach out to remove a folding table below the door, making it very convenient to use.
[0008] In the aforementioned pickup truck bed extension box, both of the slides are horizontally oriented along their length. The bracket has an arc-shaped positioning groove at the top of each slide near the opening. Both connecting rods are fixed with sliding pins and positioning pins. The sliding pins and positioning pins are horizontally oriented and spaced apart along the length of the corresponding connecting rods. The sliding pins and positioning pins on both connecting rods pass through the corresponding slides. When the connecting rod moves along the slide until the sliding pin abuts against the end wall of the slide near the opening, the positioning pin can slide upward into one end of the positioning groove until the positioning pin abuts against the end wall of the other end of the positioning groove. The sliding pin is closer to the opening than the positioning pin. With the sliding groove horizontally positioned, the connecting rod is horizontal when stored. When the connecting rod is pulled out until the sliding pin abuts against the end wall of the sliding groove, the other end of the connecting rod can swing downwards to lower the height of the tabletop hinged to the other end of the connecting rod, making it easier for the user. Simultaneously, the positioning pin slides upwards into the positioning groove until it abuts against the end wall of the positioning groove, thus positioning the connecting rod. In this way, during the use of the tabletop, the connecting rod, under the influence of gravity, keeps the positioning pin abutting against the end wall of the positioning groove. Furthermore, the cooperation between the positioning pin and the positioning groove prevents the connecting rod from moving horizontally, ensuring the stability of the connecting rod and the tabletop when pulled out for use, thus facilitating user operation.
[0009] In the aforementioned pickup truck bed extension box, the bracket is U-shaped and includes two parallel support arms and a connecting arm connecting the two support arms. One end of each support arm is fixed to the inner wall of the box body on the opening side, and the other end of each support arm is fixedly connected to both ends of the connecting arm. Two grooves are respectively formed on the two support arms. The connecting arm connects the two grooved support arms into one unit, ensuring the strength of the entire bracket, and the one-piece bracket facilitates installation.
[0010] In the aforementioned pickup truck bed extension box, a magnetic chuck is fixed inside the box, and a magnetic component is fixed on the connecting rod, which generates a magnetic attraction between the connecting rod and the magnetic chuck after the connecting rod is retracted into the box. The magnetic attraction between the magnetic chuck and the magnetic component positions the connecting rod and the box after retraction, preventing the connecting rod and table from shifting after retraction.
[0011] In the aforementioned pickup truck bed extension box, the connecting rod has an L-shaped cross-section. L-shaped connecting rods have higher strength and can be directly made from materials such as angle steel, resulting in lower costs.
[0012] Compared with existing technologies, this pickup truck's rear bed extension box integrates the table directly into the box body, allowing the table to be pushed and pulled in and out without having to lean out to take out the folding table below the sliding door, making it more convenient to use.

Detailed Implementation
[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the pickup truck bed extension box includes a square box body 1 with an open bottom. A square opening 1a is provided through one side of the box body 1. A sliding door 1b is hinged to the box body 1 and can be flipped up and down to control the opening and closing of the opening 1a. In this embodiment, the box body 1 has openings 1a in three directions other than the side facing the front of the pickup truck, i.e., the front side. The opening 1a involved in this case specifically refers to the opening 1a on the right side of the box body 1.
[0019] The pickup truck bed extension box also includes a bracket 2 fixed inside the box body 1, two long rod-shaped connecting rods 3, a square plate-shaped table 4, and two rope-shaped fasteners 5. The bracket 2 is roughly U-shaped, including two parallel support arms 2d and a connecting arm 2c connecting the two support arms 2d. The opening 1a on the bracket 2 faces right. The right ends of the two support arms 2d are fixed to the inner wall above the opening 1a on the right side of the box body 1, and the left ends of the two support arms 2d are fixed to both ends of the connecting arm 2c. Each of the two support arms 2d has a through groove 2a extending along the front-to-back direction. Both grooves 2a are elongated and horizontally arranged along the left-to-right direction. Neither end of the groove 2a penetrates the support arm 2d.
[0020] Two connecting rods 3 are arranged in parallel and spaced apart in the front-to-back direction. The cross-section of the connecting rod 3 is L-shaped, including a vertically arranged longitudinal part and a transverse part perpendicular to the longitudinal part. The transverse parts of the two connecting rods 3 are located on the opposite side of the longitudinal parts of the two connecting rods 3.
[0021] The left ends of the two connecting rods 3 are respectively slidably connected to the two sliding grooves 2a of the bracket 2. When the two connecting rods 3 slide to the right along the two sliding grooves 2a, the right ends of the two connecting rods 3 can pass through the opening 1a. In this embodiment, the two support arms 2d are provided with arc-shaped positioning grooves 2b at the top of the two sliding grooves 2a near the right end. The lower end of the positioning groove 2b is connected to the sliding groove 2a, and the groove widths of the two are approximately the same. The upper end of the positioning groove 2b extends to the upper right.
[0022] Each of the two connecting rods 3 is fixed with a sliding pin 3a and a positioning pin 3b located to the left of the sliding pin 3a. Both the sliding pin 3a and the positioning pin 3b are horizontally arranged in the front-to-back direction and are spaced apart along the length of the corresponding connecting rod 3. The distance between the sliding pin 3a and the positioning pin 3b along the length of the connecting rod 3 is the same as the horizontal distance between the right end of the slide groove 2a and the lower end of the positioning groove 2b. Both the sliding pin 3a and the positioning pin 3b on the two connecting rods 3 pass through the corresponding slide groove 2a. When the connecting rod 3 moves to the right along the slide groove 2a until the sliding pin 3a abuts against the end wall of the right end of the slide groove 2a, the positioning pin 3b can slide upwards into the lower end of the positioning groove 2b until the positioning pin 3b abuts against the upper end wall of the positioning groove 2b, thus limiting the position of the connecting rod 3.
[0023] Magnetic elements 6 are fixed to the opposite sides of the transverse portions of the two connecting rods 3. When the two connecting rods 3 move to the left and are fully retracted into the housing 1, two magnetic attracting elements are fixed at the top of the housing 1 corresponding to the positions of the magnetic elements 6. Magnetic elements 6 can generate magnetic attraction with the magnetic attracting elements. In this embodiment, the magnetic element 6 can be an iron sheet or a magnet, and the magnetic attracting elements are magnets.
[0024] The front and rear sides of the left end of the tabletop 4 are respectively hinged to the right ends of the two connecting rods 3, allowing the tabletop 4 to flip up and down relative to the two connecting rods 3. One end of each of the two fixing parts 5 is fixed to the other side of the tabletop 4. The right side of the housing 1 also has two fixing parts 1c, and the positions of the two fixing parts 1c are higher than the bottom of the opening 1a. The other ends of the two fixing parts 5 can be detachably connected to the two fixing parts 1c. In this embodiment, both fixing parts 5 are pull ropes and hooks. The upper end of the fixing part 5 can be tied to the hook for fixation, or a circular hanging ring can be fixed to the upper end of the fixing part 5 and the hanging ring can be sleeved on the hook for connection.
[0025] When the table 4 is not needed, the fixing piece 5 can be removed from the fixing part 1c. Then, lift the right end of the connecting rod 3 upwards, causing the positioning pin 3b to slide down from the positioning groove 2b into the slide groove 2a, releasing the left and right restriction on the connecting rod 3. Push the connecting rod 3 and the table 4 into the box body 1 along the slide groove 2a, causing the connecting rod 3 and the table 4 to retract into the box body 1. Close the sliding door 1b to store the table 4 inside the box body 1. Here, if needed, the right end of the table 4 can be completely flipped to the left around the hinge point so that the original top surface of the table 4 rests against the upper side of the horizontal part of the two connecting rods 3, thereby shortening the length of the part extending out of the box body 1 for easier storage.
[0026] When needed, flip the sliding door 1b upwards to open it, pull the tabletop 4 to the right, and slide the connecting rod 3 outwards along the slide groove 2a until the sliding pin 3a abuts against the right end wall of the slide groove 2a. The right end of the connecting rod 3 and the tabletop 4 protrude from the housing 1. Swing the connecting rod 3 and the tabletop 4 downwards so that the positioning pin 3b engages upwards in the positioning groove 2b and abuts against the upper end wall of the positioning groove 2b, thus limiting the connecting rod 3 in the left-right and up-down directions. Flip the tabletop 4 to a horizontal position and fix the two fixing pieces 5 fixed to the right end of the tabletop 4 to the two fixing parts 1c respectively, thus providing four-point support for the tabletop 4 and allowing the tabletop 4 to be held in its current state for use.
