[0027] The present invention is further described below in conjunction with embodiments and drawings.

[0028] like Figures 1 to 3 As shown, an electric flip mechanism includes a fixed bracket 2, a recliner 3 is installed on one side of the fixed bracket 2, and a toothed plate 5 is installed on the other side. The recliner 3 and the toothed plate 5 are installed on the same synchronization rod 4. The recliner 3 and the toothed plate 5 can rotate under the drive of the synchronization rod 4, and the toothed plate 5 is driven by a motor 7;

[0029] An arc-shaped limiting groove 201 is arranged on the fixed bracket 2, and a driving groove 501 is arranged on the tooth plate 5 opposite to the limiting groove 201. When the tooth plate 5 rotates clockwise, the position of the right side wall of the driving groove 501 can exceed the right side wall of the limiting groove 201. When the tooth plate 5 rotates counterclockwise, the position of the left side wall of the driving groove 501 can exceed the left side wall of the limiting groove 201. The length of the limiting groove 201 is greater than the length of the driving groove 501. When the tooth plate 5 does not rotate, the tail of the driving groove 501 coincides with the head of the limiting groove 201, so that the tooth plate 5 can automatically rotate around the synchronization rod 4 on the fixed bracket 2.

[0030] An unlocking piece 6 is arranged between the toothed plate 5 and the fixed bracket 2, one end of the unlocking piece 6 is fixedly sleeved on the synchronization rod 4, and an unlocking strip hole 601 is opened on the other end of the unlocking piece 6, and a protruding cylinder 502 is arranged on the side of the toothed plate 5 close to the fixed bracket 2, and the cylinder 502 extends into the unlocking strip hole 601, thereby driving the toothed plate 5 to rotate, and when the toothed plate 5 rotates, its unlocking piece 6 can drive the recliner 3 to unlock, and after unlocking, the motor 7 provides power for the rotation of the toothed plate 5, and the toothed plate 5 starts to rotate, and the external fixed bracket 2 remains stationary, and the recliner 3 can be locked when not in use, and it has strong impact resistance to prevent the toothed plate 5 from rotating uncontrollably, and its rotation process needs to be unlocked before rotation.

[0031] A reinforcing plate 10 is installed on the side of the tooth plate 5 away from the fixed bracket 2. A first through hole 1001 is opened in the middle of the reinforcing plate 10. The reinforcing plate 10 is sleeved on the synchronization rod 1 through the first through hole 1001. The reinforcing plate 10 is connected to the fixed bracket 2 by bolts via at least one bent portion set at the edge, which can strengthen the connection between the tooth plate 5 and the synchronization rod 4 to avoid falling off during rotation.

[0032] A second through hole 1002 is provided on the reinforcing plate 10, and a motor bracket 11 is installed on the outer side of the reinforcing plate 10. The motor bracket 11 has a motor through hole corresponding to the second through hole 1002, and a motor 7 is installed on the motor bracket 11. The outer end of the output shaft of the motor 7 is provided with gear teeth. The output shaft of the motor 7 passes through the motor through hole and the second through hole 1002 and engages with the tooth plate 5, so that it can drive the tooth plate 5 to rotate.

[0033] like Figures 4 to 6 As shown, an electric armrest, the electric flip mechanism is installed on one side of the armrest frame 1, wherein the angle adjuster 3 is fixed on the outer side wall of the armrest frame 1, and a driving shaft 8 is arranged on the outer side wall close to the angle adjuster 3, and the driving shaft 8 can pass through the limit groove 201 and the driving groove 501 in sequence; when the tooth plate 5 rotates clockwise or counterclockwise, the armrest frame 1 fixed by the fixed driving shaft 8 can be driven to rotate together;

[0034] A support plate 12 is also welded on the outer wall of the armrest frame 1 near the side of the angle adjuster 3, and a semicircular notch 1201 is opened on the support plate 12. One end of the drive shaft 8 is welded to the armrest frame 1, and the other end can pass through the notch 1201. The support plate 12 can provide certain support for the drive shaft 8, and jointly support the armrest frame 1 and the toothed plate 5 to rotate together.

[0035] like Figure 7 As shown, a follow-up support mechanism is provided on the side of the armrest frame 1 away from the electric flip mechanism and facing the electric flip mechanism, and the follow-up support mechanism includes a support bracket 17 and a shaft 13, wherein the shaft 13 is fixed to the armrest frame 1, and the shaft 13 is inserted into the shaft hole of the support bracket 17;

[0036] The shaft rod 13 is sleeved with a shaft sleeve 14, one end of which is against the outer wall of the armrest frame 1, and the other end is against the inner wall of the fixing bracket 2, which can reduce the wear and corrosion of the shaft rod 13; the shaft rod 13 coincides with the axis center line of the synchronization rod 4.

[0037] A limiting bracket 15 is welded on the armrest frame 1 near the side of the sleeve 14, and a limiting plate is arranged at the front end of the limiting bracket 15. A limiting notch is opened at the upper end of the supporting bracket 2, and the limiting plate can extend into the limiting notch and abut against one end of the limiting notch. The limiting bracket 15 can move in the notch as the armrest frame 1 rotates, and can limit the excessive rotation of the armrest, which would cause damage to the armrest.

[0038] The outer leaf spring 9 of the sleeve 14 and the limit bracket 15 are provided with an installation notch. The inner end of the leaf spring 9 is fixed on the sleeve 14, and the outer end thereof is stuck in the installation notch. The leaf spring 9 can eliminate the gap between the support bracket 2 and the armrest frame 1, making the movement smoother, and at the same time can balance the rotating mechanism on the other side to maintain the stability of the armrest.

[0039] like Figures 8 to 9 As shown, the armrest frame 1 also includes a connecting plate 101 and a connecting pipe 102 in a "U"-shaped structure. The connecting pipe 102 and the connecting plate 101 are respectively connected to the front and rear ends of the armrest frame 1, and an armrest shell 16 is arranged outside the armrest frame 1. The front sides of both ends of the armrest frame 1 are provided with mounting grooves in a "U"-shaped structure, and both ends of the connecting pipe 102 can be inserted into the mounting grooves and fixed. Both ends of the connecting plate 101 are surrounded by the rear ends of both sides of the armrest frame 1 to form a whole. The shell 16 is surrounded by the outside of the armrest frame 1 and can rotate with the internal armrest frame 1;

[0040] like Fig.10 As shown, the electric armrest can be turned over together with the electric turning mechanism and the follower support mechanism. After turning over, the driving shaft 8 follows the rotation of the gear plate 5 to reach the other end of the limiting groove 201 of the fixed bracket 2.

[0041] When the present invention is in use, the driving shaft 8 arranged on the armrest frame 1 is simultaneously passed through the arc-shaped limiting groove 201 and the driving groove 501, the motor 7 drives the tooth plate 5 to rotate, and the tooth plate 5 drives the synchronous 4 rods to rotate. Under the action of the synchronous rod 4, the angle adjuster 3 is unlocked. Specifically, when the tooth plate 5 rotates clockwise, the position of the right side wall of the driving groove 501 can exceed the right side wall of the limiting groove 201. Therefore, when the motor 7 drives the tooth plate 5 to rotate counterclockwise, the angle adjuster 3 is unlocked, and the right side wall of the driving groove 501 can contact the limiting column of the armrest frame 1, thereby driving the armrest frame 1 to rotate counterclockwise; when the tooth plate 5 rotates counterclockwise, the position of the left side wall of the driving groove 501 can exceed the left side wall of the limiting groove 201. When the motor 7 drives the tooth plate 5 to rotate clockwise, the angle adjuster 3 is unlocked, and the left side wall of the driving groove 501 can contact the driving shaft 8 of the armrest frame 1, thereby driving the rotating device to rotate clockwise. Due to the presence of the recliner 3, the strength can be guaranteed. After the recliner 2 is unlocked, the armrest frame 1 rotates, which can enhance the impact resistance. A follow-up support mechanism is provided on the side of the armrest frame 1 away from the electric flip mechanism, wherein the axis lines of the follow-up support mechanism and the electric flip mechanism coincide, thereby achieving concentric rotation.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present invention.
