When in use, lubricating oil is loaded into the oil chamber, and the front and rear translation of the seat is realized by making the travel gear roll on the rack. The rack cooperates with the gear to walk, which can play a role in controlling the walking direction. During the rotation of the gear, when the tooth with the oil outlet meshes with the rack, the tooth root of the rack drives the sealing head to retract into the gear, and when the sealing strip retracts, the first spring stores energy and at the same time The connecting rod drives the piston to move toward the oil chamber, and drives the lubricating oil in the oil chamber to flow through the oil passage to the oil outlet and flow to the teeth of the gear to lubricate the gear; when the sealing head is staggered with the thimble, the first spring Under the action, the sealing head re-seals the oil outlet, and the moving process of the sealing head drives the piston to move towards the air chamber.

Automatic lubrication of travel gears is realized.

As a preference, the two travel gears in the pair of travel gears are connected together through a wheel shaft, and the wheel shaft is a circular tube structure, and a circular inner rod is rotatably pierced in the wheel shaft, and the inner rod The outer peripheral surface is provided with a first friction layer, the inner surface of the wheel shaft is provided with a second friction layer, and the inner rod and the wheel shaft are abutted together through the first friction layer and the second friction layer. When the walking gears on the left and right sides receive different resistances and cause the wheel shaft to twist, the wheel shaft will rotate relative to the inner rod. When rotating, the outer friction layer and the second friction layer will generate frictional energy to eliminate the torque force, thus playing a role Improve the anti-twisting ability of the axle. The axle is designed as a tubular structure, which makes the axle light in weight and good in torsion resistance.

Preferably, the inner rod includes a left rod and a right rod, the left end of the left rod is connected with the axle through the left energy-absorbing spring, and the right end surface of the left rod is provided with several The first reversing tooth, the right end of the right rod is connected with the axle through the right energy-absorbing spring, the left end surface of the right rod is provided with a number of second reversing teeth distributed along the circumferential direction of the right rod, the The first reversing teeth and the second reversing teeth mesh together.

The brake mechanism is provided so that the car seat can reliably stay at the set position. Braking is performed through an automatic suction cup, which is not prone to vibration during braking, and there is no rigid collision between the traveling gear and the rack. The specific vibration process is to squeeze the first suction cup and the second suction cup at the same time, so that negative pressure is formed in the inner space of the first suction cup and the adsorption groove, that is, the first suction cup and the second suction cup are adsorbed on the car body together. Implement braking. The structure of the vibrating sucker can make the adsorption of the first sucker partly disengage momentarily when it is subjected to vibration or instantaneous impact force, and under the action of the second sucker, the first sucker will recover after the momentary impact force disappears. Adsorption, so that the suction cup will not fall off when it is partially disconnected due to an instantaneous impact, and the decrease in the adsorption force will be small, that is, it still maintains a good adsorption effect and good reliability.

Preferably, the suction end of the second suction cup protrudes from the suction end of the first suction cup. Because the first suction cup is located on the outside, it can be visually observed whether it is attached or not, but whether the second suction cup is attached or not cannot be visually seen, so if the first suction cup exceeds the second suction cup, there are the following shortcomings : If the pressing force is small, the second suction cup may not be adsorbed. In order to ensure the second suction cup is adsorbed, it needs to be pressed with a large force. It is difficult to grasp the force and how long it lasts, which often leads to braking.

Preferably, a plurality of elastic connecting strips connecting the first suction cup and the second suction cup are arranged in the suction groove, and the elastic connecting strips are distributed along the circumferential direction of the second suction cup. When both the first suction cup and the second suction cup are adsorbed, the elastic connecting strip is elongated to store energy, and the energy produces a tendency to prompt the first suction cup to move toward the adsorbed object, so that when the first suction cup is momentarily disconnected, the acceleration The first sucker returns to the adsorption state. That is to say, the possibility of falling off when receiving an instant impact is further reduced, in other words, the ability to resist instant impact when the suction cup vibrates is improved.

When the vibration is generated, the damping rod is deformed, and the deformation of the damping rod causes the elastic diaphragm to deform and reset toward the empty cavity. At the same time, the quicksand flows back and forth between the first filling cavity and the second filling cavity, and the quicksand flows between each other. When the quicksand flows through the friction hole, it will rub against the friction hole and the friction between the quicksand will intensify, making the effect of vibration elimination and energy absorption more significant.
