This electric wheelchair of changeable double-terminal control has designed two sets of control terminal on the body, switches the part through the double-terminal between two sets of control terminal and connects to make seat user and seat impedor all operable, two users can freely switch wheelchair control, make the double-purpose family use the scene can realize smoothly.
Description
The technical field is as follows:
the utility model relates to an electronic wheelchair technical field especially relates to an electronic wheelchair of changeable two terminal control.
Background art:
the existing electric wheelchair control system is generally connected as shown in fig. 1, and the user controls the speed and direction of the electric wheelchair through a push rod/up control/control terminal. The upper and lower controls are typically placed on the wheelchair in the position shown in figure 2. When a user sits on the wheelchair, the movement direction, speed and the like of the wheelchair can be easily controlled through the push rod, the key and the like which are controlled upwards. In a dual-user use scene, a first user sits on the wheelchair, a second user stands behind the wheelchair, and the second user needs to control the wheelchair through upper control. In this scenario, the existing scheme needs to detach the upper control installed on the wheelchair, and the second user is difficult to conveniently control the wheelchair due to the influence of the length of the connection cable between the upper control and the lower control.
The utility model has the following contents:
to the above problems, the utility model provides an electric wheelchair that changes in changeable double-terminal control of operation.
The utility model discloses a realize through following technical scheme: the utility model provides an electronic wheelchair of changeable two terminal control, includes wheelchair base, wheelchair back and wheelchair handrail, wheelchair base bottom is provided with the bottom control box, and wheelchair base one side is provided with two terminal switching parts, wheelchair back top is provided with upper portion control terminal, be provided with lower part control terminal on the wheelchair handrail, upper portion control terminal, lower part control terminal, bottom control box are connected with two terminal switching parts electricity respectively.
In a preferred embodiment of the present invention, the lower control terminal is connected to the dual-terminal switching unit through a first connection cable, the upper control terminal is connected to the dual-terminal switching unit through a second connection cable, and the bottom control box is connected to the dual-terminal switching unit through a third connection cable.
The utility model has the advantages that: this electric wheelchair of changeable double-terminal control has designed two sets of control terminal on the body, switches the part through the double-terminal between two sets of control terminal and connects to make seat user and seat impedor all operable, two users can freely switch wheelchair control, make the double-purpose family use the scene can realize smoothly.
Description of the drawings:
FIG. 1 is a schematic diagram of a prior art electric wheelchair control system;
FIG. 2 is a schematic view of a prior art electric wheelchair;
fig. 3 is a schematic structural view of the electric wheelchair capable of switching two-terminal control according to the present invention;
fig. 4 is a circuit diagram of the present invention, which can be controlled by two terminals.
Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be clearly and clearly defined.
As shown in fig. 3, the electric wheelchair capable of switching between two-terminal control includes a wheelchair base 1, a wheelchair backrest 2 and a wheelchair armrest 3, a bottom control box 4 is disposed at the bottom of the wheelchair base 1, a two-terminal switching component 5 is disposed at one side of the wheelchair base 1, an upper control terminal 7 is disposed at the top end of the wheelchair backrest 2, a lower control terminal 6 is disposed on the wheelchair armrest 3, the lower control terminal 6 is connected with the two-terminal switching component 5 through a first connection cable 8, the upper control terminal 7 is connected with the two-terminal switching component 5 through a second cable 10, and the bottom control box 4 is connected with the two-terminal switching component 5 through a third connection cable 9.
As shown in fig. 4, the power source positive cable of the first connection cable 8 of the two-terminal switching unit 5 is connected to the terminal K1 of the two-way switch, the power source positive cable of the second cable 10 is connected to the terminal K2 of the two-way switch, and the power source positive cable of the third connection cable 11 is connected to the terminal K.
The two-way switch determines that the K terminal is connected with the K1 terminal or the K terminal is connected with the K2 terminal. When the end K is connected with the end K1, the power supply anode 12 of the lower control terminal is connected, and the power supply anode of the upper control terminal is disconnected, then the lower control terminal controls the wheelchair. When the end K is connected with the end K2, the power supply anode 12 of the upper control terminal is connected, and the power supply anode of the lower control terminal is disconnected, then the upper control terminal controls the wheelchair. In the figure, reference numeral 13 denotes a power source cathode, and reference numeral 14 denotes a data line.
Finally, it should be noted that: the above embodiments are only specific embodiments of the present invention, and are not intended to limit the technical solution of the present invention, and the protection scope of the present invention is not limited thereto, although the present invention is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: those skilled in the art can still modify or easily conceive of changes in the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features within the technical scope of the present disclosure; such modifications, changes or substitutions do not substantially depart from the spirit and scope of the embodiments of the present invention, and are intended to be included within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
