The working principle of the invention is as follows:

the PED support and the dining table board are integrated and are arranged in the dining table board in a nested mode when being collected. The product structure and the dining table are connected to increase the turnover function, which is mainly realized by an asymmetric moment hinge mechanism.

The PED support is realized through an up-and-down self-adaptive adjustable mechanism, and the adjustable mechanism is mainly formed by combining a connecting rod 9 with a compression spring 6. The main function of the spring is reset and spacing keeping function, the compression range of the spring is converted by the link mechanism, and the requirement of the service life of the spring within the range of the service size is met. The spring is installed on a smooth sliding rod, the uppermost end of the spring is matched with the sliding block 11, the sliding rod penetrates through the sliding block, one end of the connecting rod structure is connected with the sliding block, a fulcrum 10 is additionally arranged in the middle of the connecting rod structure and connected, and the other end of the connecting rod structure is connected with the clamping interface. The two ends of the connecting rod are designed into a sliding groove form which moves relative to the sliding block or the clamping mechanism.

When the PED bracket is in the initial position, the plane of the bracket is jointed with the plane of the dining table board.

Before the PED support is used, the clamping mechanism is opened outwards, slides upwards, and finally transmits the acting force to the connecting rod structure matched with the PED support through the upward sliding of the clamping mechanism, and the connecting rod mechanism rotates by taking the fulcrum 10 as a rotating point under the action of the external force, so that the connecting mechanism at the other end is stressed downwards, and the sliding block matched with the connecting mechanism is pushed to move downwards; the sliding block moves downwards along the direction of the sliding rod to push the spring to compress downwards; after the equipment is used and fixed on the clamping interface, the spring is in a compressed state, so that the PED equipment is effectively limited. And the PED bracket is turned over, the viewing angle of the electronic equipment 4 is adjusted, and the environment conditions of different backward tilting angles, different percentiles and different row pitches of the backrest can be adapted.

After the electronic device 4 is taken out, the slide block is pushed to move by the acting force of the compression spring 6, so that the clamping interface is reset to the initial state. The compression range of the spring is reduced through the link mechanism, the problem that the requirement on the use range is large is solved, and the functional problem that the spring cannot generate elastic failure due to overlarge compression ratio is also solved.

In fig. 1, the electronic device 4 is fixed to the lower support base 5 by the upper clamping mechanism 2, and the support base 5 ensures that the electronic device 4 does not move downward or outward under the action of gravity and external force. The upper clamping mechanism ensures that the electronic device 4 is provided with a downward clamping without being turned upwards or outwards. In order to ensure that the electronic device 4 is effectively fixed, at least the clamping mechanism is required to ensure that the clamping function of the clamping mechanism does not move outwards or upwards under the action of the electronic device 4. To ensure that the electronic device 4 is effectively held in any position, the hinge moment on the PED bracket assembly is at least in the range of 1.5-2 times the maximum weight of the electronic device 4. To ensure that the electronic device 4 is effectively restrained downwards, the strength of the support base needs to be at least capable of bearing the sum of the gravity of the electronic device 4 and the acting force of the clamping mechanism.

In fig. 2, the compression spring 6 is in a compressed state, and exerts a certain elastic force on the slider 11 upwards, the slider 11 pushes the link 9 to rotate clockwise along the fulcrum 10, and pushes the slider mechanism 7 to exert a load downwards to act on the electronic device 4, so as to fix the electronic device 4. In order to ensure that the electronic device 4 is effectively fixed, the elastic force of the spring needs to be larger than the friction force between the slider and the slide bar 8, the friction force between the connecting rod and the fulcrum, and the like.

In fig. 3, the slider mechanism is composed of a slider 15, a retainer ring 12, a clip 13, a torsion spring 14, and a pin 16. The catch 13 on the outside of the slider is folded outwardly to provide an inward torque effect by the deformation of the torsion spring 14. The torsion of the torsion spring 14 needs to be at least 1.5 times greater than the torsion in use. Under checkpost 13 applys great exogenic action, can not produce deformation or destruction to the structure, checkpost 13 need guarantee at least that intensity can need satisfy 1.5 times of intensity under receiving ordinary exogenic action.

The above is only a preferred embodiment of the present invention, and certainly, the scope of the present invention should not be limited thereby, and therefore, the present invention is not limited by the scope of the claims.
