[0002] With the development of the automotive industry, people's demand for comfortable operation and use of automobiles is increasing. As an interior structural component used to support the passenger's arms on the car seat, the seat armrest is a key component to improve passenger comfort. Well-designed seat armrests can improve the comfort and safety of the car seat and the vehicle.

[0003] Currently, the central armrests of existing car seat products are generally manually operated and manually flipped. The armrests have a large impact when flipping and are prone to abnormal noise. In addition, the manual flip armrests are inconvenient to operate, affecting the driving experience. The existing electric flip armrests have weak impact resistance, slow speed, and non-concentric movement. Summary of the Invention

[0004] In order to solve the above technical problems, the utility model provides an electric flip mechanism and an electric armrest with strong impact resistance.

[0005] The technical solution is as follows: an electric turning mechanism, the main features of which are: a fixed bracket, a recliner mounted on one side of the fixed bracket, and a toothed plate mounted on the other side; the recliner and the toothed plate are mounted on the same synchronization rod, the recliner and the toothed plate can rotate under the drive of the synchronization rod, and the toothed plate is driven by a motor;

[0006] The fixed bracket is provided with an arc-shaped limit slot, and the tooth plate is provided with a drive slot opposite the limit slot. When the tooth plate rotates clockwise, the right side wall of the drive slot can be positioned above the right side wall of the limit slot. When the tooth plate rotates counterclockwise, the left side wall of the drive slot can be positioned above the left side wall of the limit slot. With the above structure, the motor provides power for the rotation of the tooth plate, which in turn drives the tooth plate to rotate, which in turn drives the synchronization rod. Under the action of the synchronization rod, the recliner is unlocked. The presence of the recliner ensures strength. After the recliner is unlocked, the electric tilting mechanism rotates, effectively enhancing impact resistance.

[0007] Preferably, an unlocking plate is provided between the toothed plate and the fixed bracket. One end of the unlocking plate is fixedly mounted on the synchronization rod, and the other end of the unlocking plate is provided with an unlocking strip hole. A protruding cylindrical portion is provided on the side of the toothed plate closest to the fixed bracket, and the cylindrical portion extends into the unlocking strip hole, thereby driving the toothed plate to rotate. With this structure, when the toothed plate rotates, the unlocking plate first unlocks the recliner. Once the recliner is unlocked, the toothed plate continues to rotate. After rotation is complete, the recliner can be locked using the manual recliner. This design provides strong impact resistance, preventing the toothed plate from becoming uncontrollable.

[0008] Preferably, a reinforcement plate is mounted on the outer side of the toothed plate away from the fixed bracket. A first through-hole is defined in the center of the reinforcement plate, through which the reinforcement plate is sleeved onto the synchronization rod. The reinforcement plate is connected to the fixed bracket via bolts via at least one bent portion provided on its edge. This structure better secures the internal toothed plate to the synchronization rod, preventing it from falling off during armrest rotation.

[0009] Preferably, a second through-hole is defined in the reinforcing plate, a motor bracket is mounted on the outer side of the reinforcing plate, the motor bracket defines a motor through-hole corresponding to the second through-hole, a motor is mounted on the motor bracket, and gear teeth are provided on the outer end of the motor output shaft. The motor output shaft passes through the motor through-hole and the second through-hole and engages with the toothed plate.

The recliner is mounted on the outer side of the armrest frame, and a limit post is provided on the outer side of the armrest frame near the recliner. The limit post sequentially penetrates into a limit slot and a drive slot. With this structure, the armrest frame can be electrically rotated by the electric tilting mechanism, eliminating manual rotation and reducing manpower. The structure is compact and small, easily platformized, and has a highly versatile mechanism, fast movement speed, and ease of use.

[0011] Preferably, a bracket is welded to the outer wall of the armrest frame near the recliner. This bracket has a semicircular notch. One end of the limiting post is welded to the armrest frame, while the other end fits through the notch. With this structure, welding to the housing ensures a stable connection, and the limiting post is securely mounted to the bracket. Rotation of the toothed plate drives the limiting post and the armrest frame to which the bracket is attached, thus enabling automatic rotation of the armrest.

[0012] Preferably, a follow-up support mechanism is provided on a side of the armrest frame away from the electric flip mechanism and facing the electric flip mechanism, wherein the follow-up support mechanism includes a support bracket and a shaft, wherein the shaft is fixed to the armrest frame and is inserted into a rotating shaft hole of the support bracket;

[0013] The shaft is fitted with a sleeve, one end of which rests against the outer wall of the armrest frame and the other against the inner wall of the fixed bracket. The shaft and the synchronization rod have their axis aligned. With this structure, the follower support mechanism can rotate around the shaft, while the sleeve protects the shaft from wear and corrosion, extending its service life while ensuring shaft stability. The alignment of the shaft and synchronization rod axis enables concentric rotation of the electric tilt mechanism and follower support mechanism.

[0014] Preferably, a limit bracket is welded to the armrest frame near the sleeve, a limit plate is provided at the front end of the limit bracket, and a limit notch is provided at the upper end of the support bracket, into which the limit plate can extend.

[0027] The present invention will be further described below with reference to the embodiments and accompanying 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 tooth plate 5 is installed on the other side. The recliner 3 and the tooth plate 5 are installed on the same synchronization rod 4. The recliner 3 and the tooth plate 5 can rotate under the drive of the synchronization rod 4. The tooth plate 5 is driven by a motor 7;

[0029] An arc-shaped limiting groove 201 is provided on the fixed bracket 2, and a driving groove 501 is provided 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 its driving groove 501 coincides with the head of the limiting groove 201, thereby enabling the tooth plate 5 to automatically rotate around the synchronization rod 4 on the fixed bracket 2.

[0030] An unlocking piece 6 is provided between the tooth 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 provided on the other end of the unlocking piece 6, and a protruding cylinder 502 is provided on the side of the tooth plate 5 close to the fixed bracket 2, and the cylinder 502 extends into the unlocking strip hole 601, thereby driving the tooth plate 5 to rotate. When the tooth plate 5 rotates, its unlocking piece 6 can drive the recliner 3 to unlock. After unlocking, the motor 7 provides power for the rotation of the tooth plate 5, the tooth plate 5 starts to rotate, and the external fixed bracket 2 remains stationary. The recliner 3 can be locked when not in use, and its impact resistance is strong to prevent the tooth plate 5 from rotating uncontrolled. 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 4 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 on the edge, which can strengthen the connection between the tooth plate 5 and the synchronization rod 4 and prevent it from 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, wherein the electric flip mechanism is installed on one side of the armrest frame 1, wherein the recliner 3 is fixed to the outer wall of the armrest frame 1, and a drive shaft 8 is provided on the outer wall near the recliner 3. The drive shaft 8 can pass through the limit slot 201 and the drive slot 501 in sequence; when the tooth plate 5 rotates clockwise or counterclockwise, the armrest frame 1 fixed with the fixed drive shaft 8 can be driven to rotate together;

[0034] A support plate 12 is welded to the outer wall of the armrest frame 1 near the side of the recliner 3. A semicircular notch 1201 is provided 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 gear 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 provided with a 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 axis of the shaft rod 13 coincides with the axis 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 provided at the front end of the limiting bracket 15. A limiting notch is provided at the upper end of the supporting bracket 2. 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 armrest from excessive rotation, causing damage due to excessive rotation.

[0038] The outer leaf spring 9 of the sleeve 14 and the limit bracket 15 are provided with a mounting notch. The inner end of the leaf spring 9 is fixed on the sleeve 14, and the outer end thereof is stuck in the mounting 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 and 9 As shown, the armrest frame 1 also includes a connecting plate 101 and a U-shaped connecting tube 102. The connecting tube 102 and the connecting plate 101 are respectively connected to the front and rear ends of the armrest frame 1. An armrest housing 16 is provided on the outside of the armrest frame 1. The front sides of both ends of the armrest frame 1 are provided with U-shaped mounting grooves, into which the ends of the connecting tube 102 can be inserted and fixed. The ends of the connecting plate 101 are enclosed within the rear ends of the two sides of the armrest frame 1, forming a whole. The housing 16 surrounds the outside of the armrest frame 1 and can rotate with the internal armrest frame 1.

[0040] like Figure 10 As shown, the electric armrest can flip along with the provided electric flip mechanism and the follower support mechanism. After flipping, the drive shaft 8 follows the rotation of the gear plate 5 and reaches 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 provided on the armrest frame 1 is simultaneously passed through the arc-shaped limit groove 201 and the driving groove 501, the motor 7 drives the gear plate 5 to rotate, and the gear 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 gear plate 5 rotates clockwise, the position of the right side wall of the driving groove 501 can exceed the right side wall of the limit groove 201. Therefore, when the motor 7 drives the gear plate 5 to rotate counterclockwise, the angle adjuster 3 is unlocked, and the right side wall of the driving groove 501 can contact the limit column of the armrest frame 1, thereby driving the armrest frame 1 to rotate counterclockwise; when the gear plate 5 rotates counterclockwise, the position of the left side wall of the driving groove 501 can exceed the left side wall of the limit groove 201. When the motor 7 drives the gear 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. The presence of the recliner 3 ensures strength. The recliner 2 is unlocked before the armrest frame 1 rotates, enhancing impact resistance. A follower support mechanism is provided on the side of the armrest frame 1 away from the electric flip mechanism. The axis of the follower support mechanism and the electric flip mechanism coincide, enabling concentric rotation.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
