[0047] Example:

[0048] As attached Figure 1 To be continued Figure 10 As shown:

[0049] This utility model provides a vehicle-mounted folding table structure, including a box formed by a bottom shell 2 and a mounting cover 1, which can be installed directly on side-by-side seats or embedded in the back of the seats.

[0050] A base 4 is slidably mounted inside the box, and a table 603 is mounted on the base 4 via a movable bracket 6. Figure 1 and Figure 8 As shown, a support arm 601 is rotatably mounted on the base 4, and a swing arm 602 is hinged to the support arm 601. The swing arm 602 is integrally connected to the movable bracket 6, and a table 603 is slidably mounted on the movable bracket 6. The rotation of the support arm 601 and the swing arm 602 make the storage and unfolding of the table 603 more flexible.

[0051] The support arm 601 and the swing arm 602 are connected by a first hinge 13, such as Figure 11 and Figure 12 As shown, the first hinge 13 includes a main sleeve 1301 and a secondary sleeve 1302. A flat shaft 1303 is disposed inside the main sleeve 1301 and passes through the interior of the secondary sleeve 1302. A rotating plate 1306 is disposed inside the secondary sleeve 1302. Multiple friction plates 1304 are sleeved on the flat shaft 1303. The rotating plate 1306 is sandwiched between adjacent friction plates 1304. The friction plates 1304 rotate synchronously with the main sleeve 1301 along with the flat shaft 1303, while the rotating plate 1306 rotates with the secondary sleeve 1302. Multiple spring plates 1305 are also sleeved on the flat shaft 1303 to compress the friction plates 1304 so that they abut against the rotating plate 1306, thereby generating resistance, so that the first hinge 13 can be actively suspended and can be adjusted to various angles.

[0052] The outer side of the auxiliary sleeve 1302 is also provided with a blocking plate 1308, which is used to block the rotation range of the connecting blades on the main sleeve 1301.

[0053] In other embodiments, such as Figure 13 As shown, the secondary sleeve 1302 in the first hinge 13 is rectangular, and the flat shaft 1303 can also be configured as a sleeve shaft for short shaft hinge.

[0054] In addition, a cylinder 5 is vertically installed on the mounting cover 1. The output shaft of the cylinder 5 abuts against the protruding part of the movable bracket 6. A top frame 3 is provided on the top of the box. A channel is formed in the top frame 3 for the movable bracket 6 and the table 603. The cylinder 5 can pop the base 4 out a distance, thereby pushing the table 603 and the movable bracket 6 out of the top frame 3. The user can easily pull out the table 603 for unfolding and use. At the same time, there is a handle groove on the movable bracket 6 for easy holding by the user.

[0055] Both the base shell 2 and the mounting cover 1 are equipped with multiple limit wheels 11 that rotatably support the movement of the table 603 and the base 4. That is, during the movement of the base 4, the limit wheels 11 keep the base 4 rolling and friction, making it quieter and more stable.

[0056] A column 102 is provided between the top frame 3 and the bottom of the box. The base 4 is fitted onto the column 102. The column 102 ensures the stability of the base 4's movement. A friction sleeve can also be installed between the base 4 and the column 102 to buffer the movement of the base 4 pushed by the cylinder 5 and slow down the ejection speed of the table 603.

[0057] Furthermore, a guide plate 101 is vertically installed inside the mounting cover 1, and two gears 10 are rotatably installed on the base 4. Racks are distributed on both sides of the guide plate 101, and the two gears 10 mesh with the racks on both sides of the guide plate 101. The gears 10 are damping gears, which can prevent the base 4 from moving too fast and affecting the feel and experience of use.

[0058] In addition, the tabletop 603 is composed of multiple panels, with adjacent panels hinged together. The middle panel is connected to the movable support 6. The tabletop 603 can be unfolded after being removed to expand the usable area, and the panels are connected by a second hinge 14. Figure 14 As shown, the second hinge 14 includes two connecting seats 1401. Each connecting seat 1401 has a recess 1402 in the middle. Two symmetrical hinge shafts 1403 are horizontally placed on both sides of the inner wall of the recess 1402. The two sets of hinge shafts 1403 of the two connecting seats 1401 are directly fitted with rotating sleeves 1405. A hook-shaped metal piece 1404 is engaged between the rotating sleeve 1405 and the hinge shaft 1403. The hook-shaped metal pieces 1404 on the two hinge shafts 1403 in a single connecting seat 1401 are arranged in opposite directions. When the connecting seat 1401 swings, the hook-shaped metal piece 1404 and the hinge shaft 1403 interfere with each other and generate resistance, realizing the suspension function, so that when the table 603 is opened and closed, the board can present different angles.

[0059] The mounting cover 1 has a locking mechanism for the base 4, including locking members 9 at both ends of the inner side of the mounting cover 1, and a limiting rod 12 on the base 4 that vertically corresponds to the locking members 9. Figure 4-7 As shown, the lock 9 includes a lock housing 901. The lock housings 901 of the two lock 9 are provided with lock grooves 9011 facing each other. The limiting rod 12 can be inserted into the lock groove 9011 as it moves vertically with the base 4.

[0060] Inside the lock housing 901, a first swing member 902 and a C-shaped swing member 903 are rotatably mounted on both sides. The first swing member 902 is connected to the lock housing 901 via a torsion spring 905, causing its bottom to swing to the left. The C-shaped swing member 903 is connected to the lock housing 901 via another torsion spring 905, causing its bottom to swing to the right. Figure 6 and Figure 7As shown, the torsion spring 905 drives the bottom of the first ornament 902 to rotate to the left until it abuts against the lock housing 901, while the other torsion spring 905 drives the bottom of the C-shaped ornament 903 to rotate to the right until it hangs down. At this time, one end of the C-shaped ornament 903 blocks the front of the lock groove 9011 and waits for the limit rod 12.

[0061] The C-shaped ornament 903 has a locking fork 904 at one end, and the first ornament 902 has a notch 9021 on one side above the pivot. When the limiting rod 12 moves with the base 4, the limiting rod 12 contacts the C-shaped ornament 903 and pushes the C-shaped ornament 903 upward. The front end of the C-shaped ornament 903 can push the first ornament 902 until the locking fork 904 is engaged in the notch 9021. One end of the C-shaped ornament 903 is engaged in the notch 9021, and the other end blocks the entrance of the locking groove 9011. Figure 6 The state shown.

[0062] When locked, the torsion spring 905 causes the C-shaped rocker 903 to swing downwards, which in turn causes the locking fork 904 to push the first rocker 902 to rotate clockwise and break free from the restriction of the notch 9021. However, the first rocker 902 still abuts against the lock housing 901, thus forming a jammed and locked state.

[0063] In this design, the two locking components 9 are linked by a cable 7. The top of the first swing component 902 extends out of the lock housing 901 and connects to the cable 7. Guide wheels 701 are rotatably installed at both ends of the inner side of the mounting cover 1. The two ends of the cable 7 pass over the corresponding guide wheels 701 and connect to the corresponding ends of the first swing component 902. The mounting cover 1 is provided with a control component that pushes the cable 7. The control component compresses the cable 7 as follows: Figure 6 At the arrow position, the cable 7 can pull the first ornament 902 on the two locking parts 9 respectively, causing the first ornament 902 to rotate in the opposite direction of the torsion spring 905 until the notch 9021 gets rid of the locking fork 904. Then the torsion spring 905 on the C-shaped ornament 903 will drive the C-shaped ornament 903 to reset. At this time, the limit rod 12 on the base 4 can push open the C-shaped ornament 903 to complete the unlocking.

[0064] like Figure 3 As shown, the control component includes a clamping frame 801 located inside the mounting cover 1. One end of the pull cable 7 passes through the clamping frame 801 and is connected to the first swing member 902. A telescopic rod 802 passes through the top of the clamping frame 801. One end of the telescopic rod 802 abuts against the pull cable 7, and the other end is connected to a button 8. A return spring 803 is provided between the button 8 and the clamping frame 801 and sleeved on the telescopic rod 802. When the user presses the button 8, the bottom of the telescopic rod 802 squeezes the pull cable 7, which causes one end of the pull cable 7 to pull the first swing member 902 to swing. The other end of the pull cable 7 is also pulled, which can also unlock and swing the first swing member 902 on the other locking member 9. That is, regardless of whether the limiting rod 12 on the base 4 is locked at the bottom or at the top, it can be unlocked.

[0065] When the table 603 needs to be retrieved, fold the table 603, and restore the swing arm 602 and support arm 601. Press button 8 to unlock the base 4. Due to its own weight, the table 603 follows the base 4 and slowly falls under the action of the damping gear 10 until it is released to the cylinder 5. Then, continue to press down the table 603 to move the base 4 to the bottom and lock it again.

[0066] 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.
