[0046] Example 1

[0047] Figure 1 It is a structural schematic diagram of an electric wheelchair controller provided in Example 1 of the present invention.

[0048] The electric wheelchair controller 100 includes a main control module 110, a control joystick 120 connected to the main control module 110, a nursing joystick interface 130, and four unidirectional control interfaces 140, wherein the four unidirectional control interfaces 140 include a forward direction interface, a backward direction interface, a left turn direction interface, and a right turn direction interface;

[0049] In the embodiment of the present invention, the electric wheelchair is an important tool for disabled people to recover at home, transport, see a doctor and go out for activities. It is mainly modified and upgraded by adding a high-performance power drive device, an intelligent control device and a battery component to the structure of an ordinary wheelchair. Among them, the intelligent control device of the electric wheelchair, that is, the electric wheelchair controller 100 includes a main control module 110 and a control rocker 120 connected to the main control module 110. The main control module 110 and the control rocker 120 are an integrated structure and can be detachably installed on the left or right armrest of the wheelchair to facilitate the user to operate the electric wheelchair.

[0050] In the embodiment of the present invention, in addition to the conventional control joystick 120, indicator lights, speed control and other function buttons, the electric wheelchair controller 100 also includes a care joystick interface 130, and at least five external expansion interfaces such as four unidirectional control interfaces 140, which are used for detachable electrical connection of external expansion control modules and other functional modules such as care joysticks, so as to expand the functions of the electric wheelchair and meet various user needs.

[0051] The nursing rocker interface 130 is used to connect with the nursing rocker 150 and transmit the first operation signal of the nursing rocker 150 to the main control module 110;

[0052] In the embodiment of the present invention, the nursing rocker 150 is a control rocker 120 provided for the nursing staff, which can be set on the rear armrest of the electric wheelchair after being connected to the nursing rocker interface 130 through a transmission line, so that the nursing staff of the disabled person can control the electric wheelchair through the nursing rocker 150. Among them, the nursing rocker 150 is connected to the nursing rocker interface 130 through a transmission line, and thus connected to the main control module 110, and the control function of the control rocker 120 will stop after the main control module 110 is connected to the nursing rocker 150, that is, the control right of the nursing rocker 150 takes precedence over the control rocker 120. Through the design of the nursing rocker interface 130, the nursing rocker 150 is easy to plug in and replace in case of failure, thereby improving the user experience.

[0053] The four unidirectional control interfaces 140 are used to connect to the extended control module 160 and transmit the second operation signal of the extended control module 160 to the main control module 110;

[0054] In the embodiment of the present invention, considering that people with physical disabilities cannot perform fine operations on the control joystick 120 through fine movements of fingers, a detachable electrically connected extension control module 160 is introduced on the electric wheelchair controller 100. The extension control module 160 has various types according to different groups of people with different disabilities. For example, for people who cannot operate the joystick with their fingers due to physical disabilities, the extension control module 160 can be a voice recognition module, which recognizes voice commands and then transmits the control commands to the main control module 110 through the corresponding unidirectional control interface.

[0055] In an embodiment of the present invention, the four unidirectional control interfaces 140 include a forward direction interface, a backward direction interface, a left turn direction interface, and a right turn direction interface. The reason why each interface corresponds to an operation is that people with physical disabilities are unable to perform sophisticated combination operations, such as being unable to turn left while moving forward. The design of a single operation interface is more in line with the physiological characteristics of this group of people.

[0056] The main control module 110 receives the first operation signal, and / or the second operation signal, and / or the third operation signal of the control joystick 120, and converts the first operation signal, the second operation signal or the third operation signal into a wheelchair control signal according to a preset priority conversion level.

[0057] In the embodiment of the present invention, the priority conversion level is that the first operation signal takes precedence over the second operation signal, and the second operation signal takes precedence over the third operation signal. That is, when the main control module 110 is connected to the nursing rocker 150 and the extended control module 160 through an interface, the first operation signal control of the nursing rocker 150 has the highest priority, and the first control signal output by the nursing rocker 150 is converted into a wheelchair control signal, thereby controlling the movement of the electric wheelchair. When the nursing rocker 150 does not output the first operation signal, the second operation signal of the extended control module 160 dominates the movement control of the electric wheelchair.

[0058] In an embodiment of the present invention, a control switch may be provided on the nursing rocker 150, and the control switch is used to control the opening and closing of the nursing rocker 150. That is, when the nursing rocker 150 and the extended control module 160 are connected at the same time, the first operation signal transmission of the nursing rocker 150 can be turned off by the control switch after the nursing rocker 150 operation is not needed, so as to avoid the dominant back and forth alternation between the first operation signal and the second operation signal, and avoid control disorder. Similarly, a control switch may also be provided on the extended control module 160. When the main control module 110 detects that the extended control module 160 and / or the nursing rocker 150 are connected, the control logic of the control rocker 120 can be turned off by default, or when the switch of the extended control module 160 and / or the nursing rocker 150 is detected to be turned on, the control logic of the control rocker 120 can be turned off by default. As a preferred embodiment, after the nursing rocker 150 is turned on, the extended control module 160 and the control rocker 120 are both invalid.

[0059] In the embodiment of the present invention, a care rocker interface 130 and a unidirectional control interface are provided on the electric wheelchair controller 100, so that the electric wheelchair controller 100 can be detachably equipped with a care rocker 150 and an extended control module 160. The extended control module 160 can further expand the function of the electric wheelchair, thereby making the electric wheelchair accessible to a wider range of people.
