[0015] In order to better understand the purpose, structure and function of the present application, the technical solutions of the present application will be further described in detail below in combination with the drawings and specific preferred embodiments.
[0016] In the description of the present application, it is understood that the terms "left side", "right side", "upper part", "lower part" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and "first", "second" and the like do not represent the importance of the parts, so it cannot be understood as a limitation on the present application. The specific dimensions used in the embodiments are only used to illustrate the technical solutions and do not limit the protection scope of the present application. For those skilled in the art, it is understandable that some well-known structures in the drawings and their descriptions can be omitted.
[0017] Unless otherwise explicitly specified and limited, the terms "mounting", "setting", "connecting", "fixing" and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0018] Example 1:
[0019] like Figs. 1-3 As shown, this application provides a car power armrest, including an armrest body 1. One end of the armrest body 1 is vertically and fixedly connected to the side of the armrest body 1 near the seat back panel. A second connecting member 4 is fixedly connected to the first connecting shaft 3. The other end of the second connecting member 4 is rotatably connected to the output end of a cylinder 5 through a second connecting shaft 6. The other end of the cylinder 5 is rotatably connected to a third connecting member 7. The third connecting member 7 is provided with a first connecting member mounting hole 11 for assembly and connection with the car seat back panel. A first connecting member 2 is sleeved on the first connecting shaft 3. One end of the first connecting member 2 is connected to the car seat back panel by bolts. An adjustment groove 9 is provided on the first connecting member 2 to limit the rotation of a limiting post 8 along the axial direction of the first connecting shaft 3. At least two adjustment grooves 9 are provided on the first connecting member 2 along the axial direction of the first connecting shaft 3.
[0020] The first connecting shaft 3 is fixed inside the armrest body 1 by a spline shaft, such as an internal hexagonal spline shaft.
[0021] As a preferred embodiment of the above, such as Fig. 2 As shown, the first connector 2 is U-shaped. The open end of the first connector 2 is fixedly connected to the car seat back panel. The adjustment groove 9 is located on the opposite end face of the first connector 2 and the open end. The first connecting shaft 3 is close to the side of the adjustment groove 9. The U-shaped first connector 2 facilitates internal maintenance and saves materials. At the same time, the one-sided opening setting can provide axial buffer force and play a buffering role.
[0022] As a preferred embodiment of the above, such as Fig. 3 As shown, a baffle 10 is also provided on the inner wall of the first connector 2. The baffle 10 and the adjustment groove 9 limit the two rotation directions of the limiting post 8 respectively. The rotation angle of the limiting post 8 does not exceed 90°. The limiting post 8 and the adjustment groove 9 can limit the lowest displacement position of the first connecting shaft 3 and the armrest body 1. At the same time, the adjustment groove 9 is a vertical strip shape, which can leave the adjustment groove 9 when the first connecting shaft 3 rotates. The limiting post 8 and the baffle 10 can limit the highest displacement position of the first connecting shaft 3 and the armrest body 1. The rotation angle must be less than 90°, so that the armrest body 1 and the car seat back panel can clamp the hand.
[0023] The specific working principle of the automobile armrest assisting of the application is that the first connecting piece 2 and the third connecting piece 7 are fixed through bolts and a back plate of a seat, and the back plate is an inner lining of a seat backrest; in an initial position, the air cylinder 5 deviates from one side of the back plate, and the armrest body 1 is horizontally placed; when assistance is needed, the air cylinder 5 connected with an internal power source of the automobile is started through a control unit, the bottom of the air cylinder 5 and the third connecting piece 7 rotate, the other side output end rotates through the second connecting shaft 6 and one end of the second connecting piece 4, so that the output end of the air cylinder 5 can be lifted, when being lifted, the second connecting piece 4 drives the first connecting shaft 3 to rotate, at this time, the limiting column 8 rotates counterclockwise and is separated from the adjusting groove 9, at the same time, the armrest body 1 is lifted to the rear, forming an assisting effect, and finally the limiting column 8 stops when moving to the position of the baffle 10.
[0024] The specific working principle of the automobile armrest distance adjusting of the application is that the air cylinder 5 is first driven, the limiting column 8 is separated from the first adjusting groove 9, the armrest body 1 is pulled along the first connecting shaft 3 in an axial direction, until the limiting column 8 moves to other adjusting grooves 9, and then the air cylinder 5 is reset, so that the distance can be adjusted.
[0025] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model. For ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments need not and cannot be exhausted. Any modification, equivalent replacement and improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model claims.
