Description

Technical Field

[0001] The utility model relates to the technical field of angle-adjusting motors, and particularly relates to a combined structure of a zero-gravity angle-adjusting motor for a seat. Background Art

[0002] The current backrest seat can only adjust the angle of the backrest at a comfortable speed and does not have the function of quickly adjusting in case of emergency. By controlling the current of the brushless motor, one motor can have two speeds, namely comfortable and quick response, to adjust the backrest seat. However, due to the space limitation of the seat, the motor cannot be made large, resulting in a small rated load and unable to output a large torque at high speed. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a combined structure of a zero-gravity angle-adjusting motor for a seat, which has both comfortable and quick response speeds and a large rated load, aiming at the problem that a zero-gravity angle-adjusting motor for a seat has both comfortable and quick response speeds, but due to the space limitation of the seat, the motor cannot be made large, resulting in a small rated load.

[0004] The technical problem to be solved by the utility model can be realized by the following technical solutions:

[0005] A combined structure of a zero-gravity angle-adjusting motor for a seat includes a left motor and a right motor located on both sides of the seat. The left motor and the right motor synchronously drive a seat angle-adjusting mechanism installed on the driving main shaft through a driving main shaft to realize the expected comfortable adjustment and quick return.

[0006] In a preferred example of the utility model, the seat angle-adjusting mechanism is a seat angle adjuster.

[0007] In a preferred example of the utility model, the left motor and the right motor have the same model, and both are brushless reduction motors.

[0008] In a preferred example of the utility model, the power output of the left motor and the right motor adopts multi-head worm transmission to achieve large-load output, with a not-too-high speed, improve efficiency, and reduce the transmission ratio.

[0009] In a preferred example of the utility model, the left motor and the right motor are both controlled by an external controller, and the external controller for controlling the left motor and the right motor is connected to the leads on the left motor and the right motor.

[0010] In a preferred embodiment of the present utility model, the driving main shaft is a spline, the power output ends of the left motor and the right motor are both internal splines, and the spline meshes with the internal splines of the left motor and the right motor to achieve power output.

[0011] Due to the adoption of the above technical solution, the seat angle adjustment mechanism of the present utility model is driven by two brushless motors of the same model. The brushless motor needs to have a large output torque and a high rated speed to achieve a quick return in case of an emergency, so as to achieve the expected comfortable adjustment (slow speed) or quick return of the seat, and at the same time meet the requirement of using a large torque, making the rated load relatively large.

[0015] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below with reference to specific drawings.

[0016] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0017] See Figure 1 and Figure 2 , a seat zero-gravity angle adjustment motor combination structure shown in the figure, including a left motor 10 and a right motor 20 located on both sides of the seat.

[0018] The models of the left motors 10a and 10b are the same, both being brushless motors. The left motors 10a and 10b are located on both sides of the seat and synchronously drive a seat angle adjustment mechanism (not shown in the figure) installed on the drive main shaft 20 through a drive main shaft. The seat angle adjustment mechanism is a seat angle adjuster (of course, it can also be other seat angle adjustment mechanisms). The brushless motor needs to have a large output torque and a high rated speed to achieve a quick return in case of an emergency, so as to achieve the expected comfortable adjustment (slow speed) or quick return of the seat, and at the same time meet the requirement of using a large torque, making the rated load larger.

[0019] The power outputs of the left motor 10a and the right motor 10b both adopt multi-head worm drive to achieve large-load output, with a not-too-high speed, improve efficiency, and reduce the transmission ratio.

[0020] The left motor 10a and the right motor 10b are both controlled by external controllers 30a and 30b. The external controllers 30a and 30b used to control the left motor 10a and the right motor 10b are connected to the leads 11a and 11b on the left motor 10a and the right motor 10b.

[0021] The drive main shaft 20 is a spline. The power output ends of the left motor 10a and the right motor 10b are both internal splines 12a and 12b. The spline on the drive main shaft 20 meshes with the internal spline 12a of the left motor 10a and the internal spline 12b of the right motor 10b to achieve power output.

[0022] The power supply and signals are simultaneously input into the leads 11a and 11b of the left motor 10a and the right motor 10b through the external controllers 30a and 30b. The left motor 10a and the right motor 10b drive the gears in the speed reducer to rotate according to the signals and output the torque to the internal splines 12a and 12b. The internal splines 12a and 12b synchronously drive the main shaft 20, causing the seat angle adjuster (or other driven mechanisms) installed on the drive main shaft 20 to rotate, achieving the expected comfortable adjustment (slow speed) or quick return response.

[0023] Due to the adoption of the above technical solution, the seat angle adjustment mechanism of the present utility model is driven by two same type reduction motors. The brushless motor therein needs to have a large output torque and a high rated speed to achieve a quick return in case of an emergency, so as to achieve the expected comfortable adjustment (slow speed) or quick return of the seat, and at the same time meet the requirement of using a large torque, making the rated load larger.

[0024] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above examples. What is described in the above examples and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
