[0027] A foldable work table for a car seat comprises a work table plate 1, a cross beam 2 fixed to the bottom surface of the work table plate, the cross beam being connected to a vertical beam via a damping structure of a second joint and a self-locking structure of the second joint, and a vertical beam 4 being connected to a latch 3 for fixing to an armrest of a car body via a damping structure of a first joint and a self-locking structure of the first joint.

[0028] The latch comprises a latch housing 5, a rotatable handle 6 rotatably connected to the latch housing via a rotating pin 7, the handle being connected to a transmission rod 8 in the housing, the rotation of the handle driving the transmission rod to move back and forth in the housing, the transmission rod being provided with a push block 9 for pushing a top block 10 out of the housing; the push block contacts the inclined surface of the top block via an inclined surface, thereby achieving a pushing effect on the top block.

[0029] The push blocks and the top blocks are in the form of multiple groups.

[0030] The latch works as follows:

[0031] The transmission rod and the push block are moved forward by rotating the handle, and the top block is driven to move sideways at the same time; when the top block moves sideways, an interference fit is generated in the mounting hole that matches the center armrest, thereby achieving the purpose of tightening.

[0032] The damping structure of the first joint includes a damping pin mounting hole 11 arranged on the latch, and left and right damping pin mounting holes 12 arranged at the lower end of the vertical beam. The left damping pin 13 is inserted into the damping pin mounting hole on the latch and the left damping pin mounting hole at the lower end of the vertical beam, and the right damping pin 14 is inserted into the damping pin mounting hole on the latch and the right damping pin mounting hole at the lower end of the vertical beam. The damping retaining spring 15 is tightly clamped on the damping pin to realize the damping movement of the first joint.

[0033] Functional description:

[0034] 1. The 90° folding and opening function of the mechanism is realized;

[0035] 2. Through the connection of the internal damping structures on both sides, the hovering function at any angle during operation is realized;

[0036] The damping retaining spring adopts a spring steel wire whose inner diameter after bending is smaller than the outer diameter of the damping shaft pin, so that the first joint (pin) can achieve the function of damping when rotating, and the magnitude of the damping force during rotation can be achieved by adjusting the inner diameter of the damping retaining spring; the specific damping retaining spring and related structures can adopt the same damping structure as in Chinese patent CN448182282A. The vertical beam plays a role of connecting the upper and lower parts.

[0037] The self-locking structure of the first joint includes left and right pin holes 16 arranged on the pin housing, and the left and right pin holes are respectively matched with the left and right arc holes 17 at the lower end of the vertical beam, and the ends of the left and right arc holes are in the form of enlarged holes. The locking pin 18 is inserted into the left and right pin holes and the left and right arc holes. A spring 19 is mounted on the locking pin, and a button 21 is provided on the outside of the locking part 20 at the end of the locking pin. When the locking part enters the vertical beam at the enlarged hole, since the diameter of the locking part is larger than the aperture of the arc hole outside the enlarged hole, the rotation of the locking pin is restricted to achieve self-locking, and the locking part is pushed out of the vertical beam under the action of pressing the button to achieve unlocking.

[0038] Functional description:

[0039] 1. The table top is automatically locked after being fully opened.

[0040] The damping structure of the second joint includes a damping pin mounting hole 22 arranged on the cross beam, and left and right damping pin mounting holes 23 and 24 arranged on the upper end of the vertical beam. The left damping pin 25 is inserted into the damping pin mounting hole on the cross beam and the left damping pin mounting hole on the upper end of the vertical beam, and the right damping pin 26 is inserted into the damping pin mounting hole on the cross beam and the right damping pin mounting hole on the upper end of the vertical beam. The damping retaining spring 27 is tightly clamped on the damping pin to realize the damping movement of the second joint.

[0041] The damping retaining spring is made of spring steel wire with an inner diameter that is smaller than the outer diameter of the damping shaft pin, so that the first joint (pin) can have a damping function when rotating, and the size of the damping force during rotation can be achieved by adjusting the inner diameter of the damping retaining spring; the specific damping retaining spring and related structures can adopt the same damping structure as in Chinese patent CN448182282A.

[0042] The self-locking structure of the second joint includes a pulley 28 arranged in the crossbeam, and the left and right sides of the pulley are arranged in waist-shaped holes 29 on the left and right sides of the crossbeam, and the ends of the waist-shaped holes are in the form of enlarged holes; one end of the arc-shaped connecting arm 30 is rotatably connected to the pulley, and the other end is rotatably connected to the vertical beam; the arc-shaped connecting arm plays a supporting role.

[0043] The pulley is provided with left and right pin holes 31, and a locking pin 32 is inserted into the left and right pin holes. A spring 33 is mounted on the locking pin, and a button 35 is provided on the outside of the locking part 34 at the end of the locking pin. When the locking part enters the enlarged hole at the end of the waist-shaped hole, since the diameter of the locking part is larger than the diameter of the waist-shaped hole outside the enlarged hole, the rotation of the locking pin is restricted and self-locking is achieved. The locking part is pushed out of the pulley under the action of pressing the button to achieve unlocking.

[0044] When the utility model is not in use, it is in a storage state. After the first joint is unlocked and folded 90°, and then the second joint is unlocked and folded 92.5°, the small table for the second row of passengers is in use state.
