In the present embodiment, the seat 10 can be understood as an appliance for a user to sit on, and the specific structure of the seat 10 is not limited herein. For example, in some embodiments, the seating apparatus 10 is a chair. In other embodiments, the seat 10 is a box provided with a housing chamber.

It should be understood that the specific structure of the electric vehicle 20 is not limited thereto. For example, in some embodiments, electric vehicle 20 includes a first drive assembly and a wheel, the first drive assembly coupled to the wheel for driving the wheel in rotation. In other embodiments, electric vehicle 20 includes a second drive assembly coupled to the track for driving the track in rotation and the track.

It should be understood that the specific connection manner of the electric running mechanism 20 and the seat 10 is not limited herein. For example, in some embodiments, the electric vehicle 20 and the seat 10 are detachably connected by bolts or screws. In other embodiments, the electric driving mechanism 20 and the seat 10 are fixedly connected by welding or the like.

It should be understood that the electric running gear 20 is used to move the seat 10. In a specific implementation, the electric running mechanism 20 can move in different directions under the driving of electric power. Since the seat 10 is connected to the electric driving mechanism 20, the seat 10 can be driven to move in the same direction during the movement of the electric driving mechanism 20.

In the present embodiment, the moving state of the electric traveling mechanism 20 is not limited herein. For example, in some embodiments, the movement state of electric vehicle 20 may include at least one of: uniform movement, stop movement, acceleration movement and deceleration movement.

It should be understood that, since the electric running gear 20 is connected to the seat 10 for moving the seat 10, it can also be considered that, in the case where the only device for controlling the moving state of the seat 10 is the electric running gear 20, the moving state of the seat 10 is the same as the moving state of the electric running gear 20.

It should be understood that the specific connection manner of the braking mechanism 30 and the seat 10 and/or the electric running mechanism 20 is not limited herein. For example, in some embodiments, the braking mechanism 30 is removably coupled to the seat 10 and/or the electric vehicle 20 via bolts or bolts. In other embodiments, the braking mechanism 30 is fixedly connected to the seat 10 and/or the electric driving mechanism 20 by welding or the like.

It should be understood that in the case where the brake mechanism 30 is connected to the seat 10, the brake mechanism 30 is used to control the movement state of the seat 10 and/or the electric running mechanism 20, and it is understood that the brake mechanism 30 directly controls the movement state of the seat 10, and in this case, the movement state of the electric running mechanism 20 may be automatically or manually adjusted according to the movement state of the seat 10. In this case, it is considered that the movement state of the seat 10 is controlled by the brake mechanism 30 and the electric running mechanism 20 together.

It should be understood that, in the case that the brake mechanism 30 is connected with the electric running mechanism 20, the brake mechanism 30 is used for controlling the movement state of the seat 10 and/or the electric running mechanism 20, and it can be understood that the brake mechanism 30 controls the movement state of the electric running mechanism 20 and affects the movement state of the seat 10. In this case, it is considered that the movement state of the seat 10 is controlled by the electric running mechanism 20 alone, but the movement state of the electric running mechanism 20 is controlled by the brake mechanism 30.

It should be understood that the specific method of controlling the moving state of the seat 10 by the braking mechanism 30 is not limited herein, and similarly, the specific method of controlling the moving state of the electric traveling mechanism 20 by the braking mechanism 30 is not limited herein. In a specific implementation, the method for controlling the movement state of the seat 10 and/or the electric running gear 20 by the braking mechanism 30 may be physical control or signal control, according to the mechanism of the braking mechanism 30, the seat 10 and the electric running gear 20.

It should be understood that, in some embodiments, the number of the brake mechanisms 30 may be plural, and the control reliability of the movement state of the electric vehicle 20 may be improved by controlling the movement state of the electric vehicle 20 by the plural brake mechanisms 30 in common. For example, as shown in fig. 1, the number of the brake mechanisms 30 is 1, and as shown in fig. 2 and 3, the number of the brake mechanisms 30 is 2.

It should be understood that the specific connection manner of the angular velocity sensor 40 and the seat 10 is not limited herein. For example, in some embodiments, the angular velocity sensor 40 and the seating furniture 10 are detachably connected by a bolt or a jack screw or the like. In other embodiments, the angular velocity sensor 40 and the seat 10 are fixedly connected by welding or the like. As shown in fig. 1 and 2, the connection position of the angular velocity sensor 40 and the seat 10 is not limited herein, and the installation position of the angular velocity sensor 40 may be adjusted according to actual requirements.

It is understood that the angular velocity sensor 40 is connected to the piece of furniture 10 for detecting the inclination and/or the direction of movement of the piece of furniture 10 for obtaining the first control signal may be understood as the first control signal is determined based on the inclination and/or the direction of movement of the piece of furniture 10 detected by the angular velocity sensor 40.

It should be understood that the specific content of the first control signal is not limited herein. Accordingly, the specific content of the operating state of the brake mechanism 30 is not limited herein. Wherein, the specific content of the first control signal corresponds to the specific content of the working state of the brake mechanism 30. The operating state of the brake mechanism 30 corresponds to the moving state of the seat 10 and/or the electric running mechanism 20.

For example, in some embodiments, the operating state of the brake mechanism 30 includes an on state and an off state. The first control signal includes adjusting the brake mechanism 30 to an activated state and adjusting the brake mechanism 30 to a deactivated state. When the operating state of the brake mechanism 30 is the activated state, the moving state of the electric running mechanism 20 is the stopped movement or the decelerated movement.

It should be understood that the specific manner in which the angular velocity sensor 40 determines the first control signal based on the detected inclination and/or movement direction of the seat 10 is not limited herein. In some embodiments, the angular velocity sensor 40 may determine the first control signal based on a predefined correspondence of the inclination and/or the movement direction of the seat 10 to the first control signal.

For example, in some embodiments, in the case that the inclination of the seat 10 is greater than or equal to the first threshold, the first control signal is determined to adjust the brake mechanism 30 to the activated state. In other embodiments, in the case that the rate of change of the inclination of the seat 10 is greater than the second threshold, the first control signal is determined to adjust the brake mechanism 30 to the activated state. Wherein the first threshold value and the second threshold value can be set according to requirements.

For example, in some embodiments, in the case that the moving direction of the seat 10 satisfies the preset condition, the first control signal is determined to adjust the brake mechanism 30 to the activated state. The movement direction of the seat 10 satisfies a preset condition and is used for representing that the seat 10 moves from the first direction to the second direction on the road surface with the slope, and an included angle between the first direction and the second direction is larger than a preset angle.

For ease of understanding, the following will be exemplified. As shown in fig. 6, for example, in some embodiments, in the case that the angular velocity sensor 40 detects that the inclination of the seat 10 is greater than 30 °, the inclination of the seat 10 is considered to be too large, and the electric driving device has a safety hazard, and the first control signal is determined to adjust the brake mechanism 30 to the activated state. In response to the first control signal, the operating state of the brake mechanism 30 is an activated state, at which time the brake mechanism 30 is activated, so that the brake mechanism 30 controls the moving state of the electric running mechanism 20, so that the electric running mechanism 20 stops moving or decelerates moving.

In other embodiments, the angular velocity sensor 40 detects that the moving direction is adjusted to a second direction during the process of the seat 10 moving up an incline in the first direction, and the first direction is opposite to the second direction, and it is considered that the electric driving device slides down an incline, and there is a safety hazard, so that the first control signal is determined to adjust the brake mechanism 30 to the activated state. In response to the first control signal, the operating state of the brake mechanism 30 is an activated state, at which time the brake mechanism 30 is activated, so that the brake mechanism 30 controls the moving state of the electric running mechanism 20, so that the electric running mechanism 20 stops moving or decelerates moving.

It should be understood that the angular velocity sensor 40 is connected to the brake mechanism 30 for controlling the operating state of the brake mechanism 30 by the first control signal. The operation state of the brake mechanism 30 can be understood as a control condition of the brake mechanism 30 on the movement state of the seat 10. Therefore, the operation state of the brake mechanism 30 affects the movement state of the seat 10.

Through the arrangement of the angular velocity sensor 40, when the angular velocity sensor 40 detects that the inclination of the seat 10 is large and/or the moving direction is abnormal, the working state of the brake mechanism 30 can be controlled through signals, and then the moving state of the seat 10 and/or the electric driving mechanism 20 is controlled through the brake mechanism 30, so that the possibility that the seat 10 is excessively inclined or the moving direction is abnormal in the driving process is reduced, and the stability and the safety of the electric driving device in the driving process are improved.

As shown in fig. 3, in the case that the angular velocity sensor 40 determines that the seat 10 is traveling uphill according to the inclination and the traveling direction of the seat 10, the first processor controls the first controller to normally rotate the brake assisting mechanism 302 based on the signal of the angular velocity sensor 40, and adjusts the relative position of the brake assisting mechanism 302 and the seat 10 so that the brake assisting mechanism 302 contacts with the slope and is located behind the electric traveling mechanism 20, where behind is understood to be behind in the moving direction of the seat 10. At this time, the brake assisting mechanism 302 supports the movement of the seat 10 behind the electric driving mechanism 20, and improves the smoothness of the movement of the seat 10 on an uphill slope.

In the case where the angular velocity sensor 40 determines that the seat 10 is driving downhill by the inclination and the driving direction of the seat 10, the first processor causes the first controller to control the normal rotation of the auxiliary brake mechanism 302 based on the signal of the angular velocity sensor 40, and adjusts the relative position of the auxiliary brake mechanism 302 and the seat 10 so that the auxiliary brake mechanism 302 is in contact with the slope.
