[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1

[0039] See also Figure 1-8 , the present invention provides a technical solution:

[0040] like Figure 1 As shown in the figure, an electric wheelchair provided with a drone control structure includes a wheelchair frame 100, and armrests 102 are fixedly connected to the wheelchair frame 100 on both sides through baffles 101. A seat plate 107 that can be positioned and flipped is installed on the wheelchair frame 100. After the seat plate 107 is flipped, a storage compartment 400 can be formed between the two baffles 101 and the backrest 109; the storage compartment 400 can be used to store supplies. Judging from the load capacity of the wheelchair, the general load capacity can reach at least 100kg.

[0041] When implementing, Figure 1 and Figure 5As shown in , an operating joystick 106 is installed on one of the armrests 102; it also includes a drone 200, and the lower end of the drone 200 is connected to an operating sleeve 207 through a cable 206. The operating sleeve 207 can be sleeved on the operating joystick 106 and can push the operating joystick 106.

[0042] Specifically, Figure 7 As shown in , a servo motor 208 arranged vertically downward is fixedly installed inside the operating sleeve 207 (the servo motor 208 can accurately control the angle and forward and reverse rotation), and the output shaft of the servo motor 208 is fixedly connected to a horizontally arranged electric push rod a212 through an arc rod 211, and one end of the piston rod of the electric push rod a212 is fixedly connected to a push plate 214, and the position of the electric push rod a212 can be adjusted by rotating the servo motor 208, and the electric push rod a212 and the push plate 214 can push the operating joystick 106 to operate the wheelchair to move or turn; the servo motor 208 and the electric push rod a212 are both controlled by the drone 200. The above method, when operated by the drone 200, needs to be debugged according to the image sent back by the drone 200 (obtained by the camera B202). For example, after the operating sleeve 207 and the operating joystick 106 are put on, the electric push rod a212 is operated to push. Since it is a blind operation, it is impossible to determine whether the electric wheelchair is moving forward, backward, turning left or right; try first, and then control the servo motor 208 to rotate 90°, 180° or other rotation degrees to operate and control the movement of the electric wheelchair.

[0043] When implementing, Figure 5 As shown, a truncated platform 104 is fixedly connected to the armrest 102, and an operating rocker 106 is installed at the top center of the truncated platform 104; the interior of the operating sleeve 207 is configured as a bell mouth that can be sleeved on the truncated platform 104; under gravity or manual operation, the operating sleeve 207 can be sleeved on the truncated platform 104; the operating sleeve 207 can be aligned and sleeved on the truncated platform 104.

[0044] During implementation, the truncated cone 104 can also be set as a triangular prism, a quadrangular prism, a hexagonal prism, etc. The design of the prism ensures that the operating sleeve 207 will not rotate easily after being put on the operating rocker 106. Since the prism is difficult to align, when it is designed as a prism, the upper end of the prism should be rounded and small. A vibration motor can also be appropriately installed in the operating sleeve 207 to vibrate through the vibration motor, making it easier for the operating sleeve 207 to be put on the operating rocker 106.

[0045] When implementing, Figure 5As shown in the figure, a button 105 is installed around the top of the round table 104, a vertical downward electric push rod b213 is fixed on the arc rod 211, and an L-shaped push rod 215 is fixedly connected to one end of the piston rod of the electric push rod b213. By operating the electric push rod b213, the button 105 can be pressed down and operated. The electric push rod b213 is controlled by the drone 200. Some additional functions can be realized by the button 105, such as the electric wheelchair itself has a brake or lighting system, and the button 105 can be unlocked and the lighting can be turned on.

[0046] In addition, a metal ring 103 is fixedly installed on the handrail 102, and the metal ring 103 is sleeved on the lower outer side of the truncated table 104. A ring-shaped electromagnet 216 is fixedly installed on the bottom of the operating sleeve 207; the electromagnet 216 and the metal ring 103 facilitate the operation sleeve 207 to be fixed on the handrail 102 by magnetic attraction, wherein the electromagnet 216 is controlled by the drone 200. Through magnetic attraction, the cooperation between the operating sleeve 207 and the handrail 102 is more stable.

[0047] It should be noted that a camera A209 is installed inside the operating sleeve 207, and a lighting lamp 210 is also installed on the camera A209. The inside of the operating sleeve 207 can be clearly observed through the camera A209 and the lighting lamp 210, which is convenient for operating the operating rocker 106. In practice, the camera A209 can be installed on the arc rod 211 or on the inner wall of the operating sleeve 207; and the surface of the round table 104 and the operating rocker 106 can also be engraved with some identification marks or scales, etc., for easy identification.

[0048] like Figure 6 As shown in the figure, a radar ranging sensor I201 is fixedly installed on the top of the drone 200, a camera B202 is installed on the bottom of the drone 200, a protective ring 204 is fixedly connected to the side of the drone 200 through a connecting rod 203, and a radar ranging sensor II205 is fixedly installed on the outside of the protective ring 204. The radar ranging sensor I201, the camera B202 and the radar ranging sensor II205 are used to detect obstacles and pedestrians, and prevent the drone 200 from touching obstacles or pedestrians when flying at low altitude. The drone 200 plays the role of escort when pedestrians are riding, and can also fly at low altitude. In order to improve safety, it needs to be protected by the protective ring 204, and it also needs to avoid rising too high and hitting the ceiling.

[0049] Instructions for use:

[0050] When in use, the operating sleeve 207 is dropped manually or by operating the drone 200 and is mounted on the operating rocker 106; the operating sleeve 207 can be controlled by operating the drone 200, thereby operating the electric wheelchair. The electrical components in the operating sleeve 207 are connected to the circuit control board built into the drone 200 through the cable 206.

[0051] During implementation, a hook can be provided at the bottom of the drone 200 to hang small items and then place them on the electric wheelchair; a small winch can also be installed at the bottom of the drone 200, and the cable 206 can be wound around the wheel of the small winch, so that the cable 206 can be freely retracted and released, which is very convenient.

[0052] Example 2

[0053] Different from Example 1, Figure 2-Figure 4 As shown, a shaft sleeve 114 is fixedly connected to the side surface of one end of the seat plate 107, and the shaft sleeve 114 is rotatably mounted on a fixed shaft 113, and the fixed shaft 113 is fixedly mounted on the wheelchair frame 100. A torsion spring 115 is sleeved on the fixed shaft 113, and one pin 116 of the torsion spring 115 is fixedly connected to one side of the seat plate 107, and the other pin 116 of the torsion spring 115 is fixedly connected to the wheelchair frame 100; a stopper 112 for limiting the flipping position of the seat plate 107 is fixedly connected to one side of the armrest 102, and an electromagnetic pin 110 is installed at the lower part of one side of the seat back 109. , the upper part of the electromagnetic pin 110 is set as a slope surface 111; a bayonet 108 is opened on one side of the seat plate 107, and when the seat plate 107 is flipped and kept horizontal, the bayonet 108 can be stuck on the electromagnetic pin 110; the electromagnetic pin 110 is controlled by the single-chip controller of the wheelchair, and one of the buttons 105 on the round table 104 can control the electromagnetic pin 110 through the single-chip controller; that is, when the button 105 is pressed, the seat plate 107 automatically bounces open and flips to the position on the side of the stopper 112 under the elastic restoring force of the torsion spring 115.

[0054] According to the above design, the flipping and opening of the seat plate 107 can be controlled remotely, and the opening method is simple in structure and easy to operate. When riding is needed, the materials in the storage compartment 400 are taken out, and then the seat plate 107 is flipped manually to keep it horizontal, and the bayonet 108 is stuck on the electromagnetic pin 110 to lock it.

[0055] Example 3

[0056] Different from Example 2, a wheelchair power box 306 is slidably installed at the lower part of the wheelchair frame 100, a main power shaft 305 is installed through the wheelchair power box 306, and wheel axles 301 are slidably installed at both ends of the main power shaft 305. The bottom of the wheelchair frame 100 is also provided with a wheel spacing adjustment mechanism that can adjust the distance between the two rear wheels 300 and the distance between the front wheels and the rear wheels 300.

[0057] In which, during implementation, the wheel spacing adjustment mechanism includes two groups of electric push rods c308 and one group of electric push rods d309; in order to maintain higher stability, the electric push rods c308 and the electric push rods d309 can also be replaced by electric hydraulic rods.

[0058] More specifically, one end of the wheel axle 301 is fixedly connected to a hexagonal prism 303, the end of the main power shaft 305 is provided with a hexagonal sliding hole 304, the hexagonal prism 303 is slidably installed in the hexagonal sliding hole 304, and a support bearing 302 is mounted on the wheel axle 301; the electric push rod c308 is fixedly installed on one side of the wheelchair power box 306, and one side of the piston rod of the electric push rod c308 is fixedly connected to the support bearing 302 through a connecting rod 310.

[0059] The electric push rod d309 is fixedly installed on the wheelchair frame 100, and one end of the piston rod of the electric push rod d309 is fixedly connected to one side of the wheelchair power box 306. The top of the wheelchair power box 306 is fixedly connected with a slider 307, and the slider 307 is slidably installed on the track groove (not shown in the figure) at the bottom of the wheelchair frame 100.

[0060] The above design can adjust the distance between the two rear wheels 300 and the distance between the front wheel and the rear wheel 300 through the wheel spacing adjustment mechanism. In this way, the distance between the overall support points of the wheelchair can be expanded, making the center of gravity of the wheelchair more stable. It will not tip over when carrying heavy materials, and it can also carry more loads. For some special terrains, such as narrow bridge decks, stones on the ground, etc., the distance between the rear wheels 300 can also be adjusted to avoid them, which is more convenient.
