It should be noted that in addition to providing the reinforcing plate 4 and the reinforcing plate 9 at the same time, only the reinforcing plate 4 can also be provided, or only the reinforcing plate 9 can be provided. In addition, in order to further improve the rotation smoothness of the armrest body 1, a bushing is also provided in the rotation hole of the armrest body 1, and the bushing is sleeved on the light rod part of the step bolt 8.

[0056] As a preferred embodiment, the driving unit 2 of this embodiment is used to output rotational power, and in combination with Figures 4 to 6 As shown in , the transmission part includes a driving gear 6 and a driven gear 3 that are meshed and connected. The driving gear 6 is arranged on the power output shaft of the driving part 2, and the driven gear 3 is fixed on the base and is coaxially arranged with the rotation axis of the armrest body 1. The transmission part of this embodiment includes a driving gear 6 and a driven gear 3 that are meshed and connected, and has a simple structure, which is easy to design and implement. It also has good force transmission stability, which is conducive to smoothly adjusting the angle of the armrest body 1.

[0057] At this time, in order to improve the installation stability of the driving unit 2, Figure 3 and Figure 4 As shown in , the armrest body 1 is provided with a mounting plate 5, and the mounting plate 5 is located outside the mounting cavity. In addition, the drive unit 2 is connected to the armrest body 1 and the mounting plate 5 to improve the installation firmness of the drive unit 2. As a preferred embodiment, the driven gear 3 is specifically welded to the base body 101. In addition, as shown in Figure 8 As shown in , the mounting plate 5 of this embodiment includes a connecting portion 501, an extending portion 502, and a transition portion 503 disposed between the connecting portion 501 and the extending portion 502. Moreover, the connecting portion 501 is connected to the armrest body 1, and the extending portion 502 is spaced apart from the armrest body 1, and an installation space is formed, and the driving gear 6 is disposed in the installation space.

[0058] In this embodiment, the mounting plate 5 includes a connecting portion 501, an extending portion 502 and a transition portion 503, and the extending portion 502 is spaced apart from the armrest body 1 to form a mounting space, which not only facilitates the arrangement of the driven gear 3, but also enables the mounting plate 5 to have a good structural strength, and can improve the arrangement stability of the driving part 2. Figure 8As shown in , the mounting plate 5 is in the shape of a long strip, so that it can be easily connected to the limit column described below while being connected to the driving part 2. In addition, in order to improve the installation firmness of the driving part 2, two connecting holes are provided on the mounting plate 5, and the mounting plate 5 is connected to the handrail body 1 and the driving part 2 together through bolts passing through the connecting holes.

[0059] As a further implementation method, Figure 8 As shown in , a socket 5021 is provided on the mounting plate 5, and the rotating shaft of the driving gear 6 is inserted in the mounting hole. With such a configuration, the mounting plate 5 can provide support for the driving gear 6, thereby improving the force transmission effect of the driving gear 6. Here, it should be noted that in addition to connecting the driving part 2 with the armrest body 1, the driving part 2 can also be connected only to the armrest body 1. In addition, in addition to providing the socket 5021 on the mounting plate 5 for inserting the rotating shaft of the driving gear 6, it is also possible not to provide the socket 5021 on the mounting plate 5, and it is also feasible to only connect the driving gear 6 with the power output shaft of the driving part 2.

[0060] As a further implementation, the seat armrest assembly of this embodiment further includes a limiter for limiting the rotation angle of the armrest body 1. In addition, the limiter includes a limiter post provided on the armrest body 1 or the driving part 2, and a limiter slot 301 provided on the base and / or the driven gear 3, and the limiter post is inserted into the limiter slot 301. As a preferred embodiment, Figure 5 , Figure 6 and Fig. 9 and Fig.10 As shown in , the limiting column of this embodiment is provided on the driving part 2, and the limiting groove 301 is provided on the driven gear 3, and is preferably an arc groove provided along the circumference of the driven gear 3. In addition, it should be mentioned that, because the rotation angle of the armrest body 1 is within a certain range, the driving gear 6 only cooperates with part of the teeth of the driven gear 3 during the rotation of the armrest body 1. Therefore, in addition to providing teeth on the entire periphery of the driven gear 3, teeth can also be provided at the position where it cooperates with the driving gear 6.

[0061] At this time, in order to further improve the use effect, such as Figure 5 As shown in , the limiting column is connected to the mounting plate 5 to improve the connection firmness between the driving part 2 and the mounting plate 5. And, as a preferred embodiment, to achieve the connection, an external thread is provided on the limiting column, and the limiting column is connected to the mounting plate 5 through a nut. At this time, in order to improve the sliding smoothness of the limiting column in the limiting groove 301, a limiting sleeve 7 is provided on the outer sleeve of the limiting column, and the limiting sleeve 7 is preferably made of rubber to prevent contact with the driven gear 3 and produce abnormal noise.

[0062] It is understandable that, in addition to providing the limiting column on the driving part 2 and the limiting groove 301 on the driven gear 3, the limiting column can also be provided on the armrest body 1. Alternatively, providing the limiting column on the driven gear 3 and the limiting groove 301 on the armrest body 1 can both achieve the limitation of the rotation angle of the armrest body 1.

[0063] In order to further improve the use effect, the driving part 2 of this embodiment can adopt a Hall motor that works by utilizing the Hall effect. In this motor, the Hall sensor is used to detect the position of the rotor, which is the key to realizing precise control of the motor. In particular, in a brushless DC motor, the Hall sensor can feedback the position information of the rotor in real time, so that the motor controller can accurately control the operation of the motor. As a result, when the seat back is adjusted, the armrest body 1 adaptively adjusts its opening angle to keep the armrest horizontal, and when the door is opened, it is conducive to automatically lifting the armrest. Of course, in addition to using a Hall motor, the driving part 2 can also use an ordinary driving motor and combine it with an angle position sensor of the armrest. This structure is also conducive to realizing automatic adjustment of the angle of the armrest body 1.

[0064] The seat armrest assembly of this embodiment, by adopting the above structure, can not only adjust the angle of the armrest body 1, but also be convenient to fold up for getting on and off the vehicle. At the same time, by arranging the drive unit 2 in the accommodating cavity of the armrest body 1, the arrangement of the drive unit 2 is convenient, and the space occupied by the seat back can be reduced, which is convenient for implementation.

[0065] In addition, another purpose of this embodiment is to provide a seat, on which the above seat armrest assembly is provided.

[0066] In addition, this embodiment also provides a vehicle, on which the above seats are provided.

[0067] The vehicle and seat of this embodiment have all the beneficial effects of the above-mentioned seat armrest assembly, which will not be described in detail here.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
