The hinging of the leg rest device 2 with the seat is realized by the leg rest mounting bracket 25, which on the one hand facilitates the connection and on the other hand facilitates the provision of a corresponding rotation space for the rotation of the primary leg rest relative to the seat.
The leg rest device 2 further comprises a shielding plate 24, one end of the shielding plate 24 is fixed at the bottom of the primary leg rest component 21, the other end of the shielding plate 24 extends towards the secondary leg rest component 22, and when the leg rest device 2 is in an open state, the end of the shielding plate 24 is covered by the end of the secondary leg rest component 22. The screening plate 24 is used to screen the components below the leg rest 2, on the one hand, to be more secure and reliable, and on the other hand, to be more aesthetically pleasing.
The sliding connection form of the primary leg support component 21 and the secondary leg support component 22 is not limited, the secondary leg support component 22 can be sleeved outside the primary leg support component 21, and the secondary leg support component 22 and the primary leg support component 21 can slide relative to each other in a sliding rail or pulley manner; the secondary leg rest assembly 22 may also be butted against the primary leg rest assembly 21, and the secondary leg rest assembly 22 can slide away from or close to the primary leg rest assembly 21, although the sliding manner may also be in the form of a slide rail or a pulley.

The primary leg support assembly 21 and the secondary leg support assembly 22 are fixed with the first slide rail 27 and the second slide rail 28 through bolts respectively, and the two slide rails are matched with each other and realize a sliding function.
The working principle of the leg rest device 2 provided by the embodiment is as follows:
when the leg support device 2 needs to be turned over to be flush with the seat and extend forwards, the switch button is started, the motor 2311 is driven to rotate forwards and drive the screw rod to move towards the front end of the seat. The screw rod pushes the driving member 2321a to rotate forward, and under the action of the driving member 2321a, the first hinge point 2321c of the connecting rod 2321c1The same as the motion track of the active member 2321 a. Second hinge point 2321c2Also as the link 2321c moves, the second hinge point 2321c2A force is applied to the rotary member to rotate the rotary member upwardly around the front end of the seat, and since the primary leg rest assembly 21 is rigidly connected to the rotary member, the rotary member rotates while the primary leg rest assembly 21 also rotates. Third hinge point 2321c of linkage 2321c3Under the combined action of the driving member 2321a and the rotating member, the third hinge point 2321c moves away from the primary leg rest assembly 213Has an arc line with the third hinged point 2321c3The hinged sliding member 2322 also moves away from the seat, and the sliding connection bracket 2326 is fixed with the secondary leg rest assembly 22, and the secondary leg rest assembly 22 has a limiting effect on the sliding connection bracket 2326 at the third hinged point 2321c3Of the sliding member 2322 and the sliding connecting bracket 2326The two-stage leg rest component 22 is pushed to move towards the direction far away from the one-stage leg rest component 21 under the combined action, and then the extension function of the leg rest device 2 is realized. When the active member 2321a rotates to a position where it cannot rotate any more, the leg rest 2 is in an open state, at this time, the top surface of the leg rest 2 is flush with the top surface of the seat, and the length of the leg rest 2 is the longest.
When the leg rest device 2 needs to be turned over to be stored on the front end face of the seat, the switch button is started again, and the driving motor 2311 rotates reversely and drives the screw rod to move towards the rear end of the seat. The screw rod pulls the driving member 2321a to rotate backwards, and the third hinged point 2321c of the connecting rod 2321c is under the acting force of the driving member 2321a and the rotating member3Moving toward the primary leg rest assembly 21, the sliding member 2322 is at the third hinge point 2321c3Is moved in a direction approaching the primary leg rest assembly 21. At third hinge point 2321c3The sliding member 2322 and the sliding connecting bracket 2326 cooperate to move the secondary leg rest assembly 22 toward the primary leg rest assembly 21. The driving member 2321a continues to rotate, and the primary leg rest assembly 21 starts to rotate until the front end of the seat is retracted.
The whole process can be completed only by driving one driving motor 2311, so that the production cost is greatly saved. And the operation is very simple, and two functions can be realized simultaneously only by pressing the button once.
