[0028] As attached Figure 1 To be continued Figure 9 As shown: This utility model provides a car trunk table structure that is convenient for camping, including a main board 1 and a table 2. Multiple connecting tubes 101 are provided on the inner side of the main board 1. The connecting tubes 101 are hollow columnar formed by the recess of the main board 1 and are used to pass through the inner side of the car trunk cover. Bolts can be passed through the connecting tubes 101 to connect the main board 1 and the trunk cover. A cover 102 is provided on the front side of the main board 1 to cover the recessed connecting tubes 101. The bottom of the main board 1 and the table 2 are connected by a hinge 3, so that the table 2 can rotate around the hinge 3 to open or close the table 2. Furthermore, a locking mechanism 4 is provided between the motherboard 1 and the desktop 2, such as... Figure 3 ,like Figures 7 to 9 As shown, the locking mechanism 4 includes a tail frame 401 mounted on the main board 1, a front frame 402 slidably disposed on the front side of the tail frame 401, a first spring 403 disposed between the front frame 402 and the tail frame 401, and a button 404 disposed on the front frame 402. Pressing the button 404 can cause the front frame 402 to slide close to the tail frame 401, and releasing the button 404 will reset the front frame 402. A locking pin 408 is installed on the front frame 402. A locking groove 7 corresponding to the locking pin 408 is opened on the movable plate 305. The locking pin 7 slides up and down in the figure, pushing the front frame 402 closer to the tail frame 401, causing the locking pin 408 to disengage from the locking groove 7. Figure 8 and Figure 9 As shown, a locking frame 405 is slidably mounted on the tail frame 401. The bottom of the locking frame 405 is connected to a locking pin 408. A second spring 407 is provided between the top of the locking frame 405 and the tail frame 401. An inclined step 4021 is provided inside the front frame 402. A brake block 406 is provided on the locking frame 405 that abuts against the inclined step 4021. The movement of the inclined step 4021 pushes the brake block 406 upward, causing the locking pin 408 to disengage from the locking groove 7. The inclined step 4021 on the locking frame 405 moves to the right as the button 404 is pushed. The rightward movement of the inclined step 4021 pushes the brake block 406, causing the locking frame 405 and the locking pin 408 to move upward. After the locking pin 408 disengages from the locking groove 7, the table 2 can fall down. When the button 404 is released, the first spring 403 drives the front frame 402 to reset, and the second spring 407 drives the locking frame 405 to reset.

[0029] The front bottom of the locking pin 408 is tilted so that the table 2 can be closed directly. As the table 2 approaches the main board 1, it pushes the locking pin 408 upward until the locking groove 7 moves below the locking pin 408. Then, the second spring 407 drives the locking pin 408 to automatically engage in the locking groove 7 to complete the fixation.

[0030] In this embodiment, the hinge 3 includes a connecting shaft 304, such as... Figures 4 to 6As shown, a fixed plate 301 is installed on the main board 1, and a movable plate 305 is installed on the table 2. A swing arm 303 is provided on the movable plate 305. A connecting arm 3011 extends from the fixed plate 301. A connecting shaft 304 passes through the connecting arm 3011. One end of the swing arm 303 is sleeved on the connecting shaft 304. An adjusting ring 308 and an elastic ring 309 are respectively provided on the connecting shaft 304. The elastic ring 309 pushes the adjusting ring 308 to abut against the swing arm 303. A resistance seat 306 is provided on the swing arm 303. Two protrusions are symmetrically arranged on the side of the resistance seat 306. The adjusting ring 308 abuts against the resistance seat 306. The abutting surface of the adjusting ring 308 is provided with two fastening areas and loosening areas. Each fastening area and each loosening area are staggered. A nut 310 is threaded onto the end of the coupling 304. The nut 310 abuts against the elastic ring 309, and the friction plate 307 is slidably connected to the coupling 304. The elastic ring 309 consists of two sets of elastic collars, each truncated cone-shaped. The two sets of elastic collars are symmetrically arranged. When the elastic ring 309 is compressed, it deforms, and the two sets of elastic collars come into close contact. When the compressive force decreases, the elastic ring 309 elastically recovers its shape, and the two sets of elastic collars return to their original positions and move away from each other. Figure 6 As shown, a friction plate 307 is also provided between the nut 310 and the elastic ring 309 to protect the elastic ring 309.

[0031] The swing arm 303 extends through the bottom notch of the main board 1 and is connected to the table 2 via the movable plate 305. A protective cover 302 is provided on the swing arm 303 to prevent the swing arm 303 from rubbing against the main board 1 and to effectively protect the swing arm 303 from contact with the outside world.

[0032] The elastic ring 309 pushes the adjusting ring 308 to contact the resistance seat 306. In the initial closed state of the tabletop 2, the convex slope of the resistance seat 306 corresponds to the loose area of ​​the adjusting ring 308, so that after the button 404 is pressed to contact the locking of the tabletop 2, the tabletop 2 can easily pop out, reducing the friction at the hinge 3. After the tabletop 2 pops out, the swing arm 303 rotates, causing the convex slope to enter the fastening area. The opening angle of the tabletop 2 in the fastening area is less than 30 degrees, and the squeezing friction in the fastening area keeps the tabletop 2 in a stationary state. At this time, it is assumed that after the tabletop 2 is flipped down, the tabletop 2 overcomes the fastening area, and the convex slope leaves the fastening area, causing the tabletop 2 to continue to flip down until the tabletop 2 is flipped down 60 degrees. Then the convex slope enters the fastening area again, and the friction of the hinge 3 increases again. However, at this time, due to the rearward shift of the center of the tabletop 2, the torque generated by the weight of the tabletop 2 overcomes the friction, and the tabletop 2 slowly flips down until it is horizontal. While keeping quiet, it also reduces the impact of the tabletop 2 flipping down to the horizontal on the hinge 3, improving the user experience.

[0033] Meanwhile, friction plates 307 are provided between the resistance seat 306 and the swing arm 303, as well as between the swing arm 303 and the connecting arm 3011, to prevent the swing arm 303 from directly contacting the connecting arm 3011 and causing wear and deformation. In addition, the friction plates are made of rubber, which makes them quieter. The reason why the swing arm 303 can generate friction with the adjusting seat 308 when it flips is that... Figure 6 As shown, a planar notch is provided on the connecting shaft 304 along its length direction, so that the adjusting ring 308 and the connecting arm 3011 can only slide relative to the connecting shaft 304, the swing arm 303 and the resistance seat 306 can rotate around the connecting shaft 304, while the connecting arm 3011, the adjusting ring 308 and the friction plate 307 are stationary relative to the connecting shaft 304.

[0034] Both the motherboard 1 and the tabletop 2 have hidden slots 5 on both sides. A pull rod 6 is hinged in the hidden slot 5. One end of the pull rod 6 is hinged to the motherboard 1 and the other end is hinged to the tabletop 2. The pull rod 6 includes two rotatably connected connecting rods. When the tabletop 2 is folded down, the pull rod 6 changes accordingly until the tabletop 2 is horizontal. The pull rod 6 straightens, restricting the position of the tabletop 2 and improving the load-bearing capacity of the tabletop 2. When the tabletop 2 is returned to the motherboard 1, the pull rod 6 can be folded up and stored in the hidden slot 5.

[0035] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
