[0016] In order to make the technical means for realizing the present invention, the creative features, the purpose and the effect easily understood, the present invention is further explained below in conjunction with specific diagrams. In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an integral connection or a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be internal communication between two components.

[0017] Example 1

[0018] like Figure 1-4 The illustrated wheelchair controller with lighting comprises an upper shell 1, the bottom of which is detachably connected to a waterproof connecting shell 5, the bottom of which is connected to a lower shell 6, the inner side of the waterproof connecting shell 5 being made of hard plastic, and the outer wall of the waterproof connecting shell 5 being made of silicone material. When the upper shell 1 is connected to the waterproof connecting shell 5, the outer wall of the silicone material can wrap the bottom end of the upper shell 1, thereby enhancing the waterproof performance and preventing rainwater and the like from entering the lower shell 6 and damaging the circuit components and the like in the lower shell 6. The bottom of the lower shell 6 is connected to a control box 7, one side of which is provided with a control interface 8, which is connected to the driver of the electric wheelchair via a signal line to realize control of the electric wheelchair. An LED light 12 is provided on the side of the shell 6 away from the wheelchair, which can illuminate the road in front of the wheelchair at night. Reflective strips 23 are connected to both sides of the lower shell 6 that are close to each other. When the wheelchair is used at night, pedestrians or vehicles on both sides can be warned, thereby improving the safety of using the electric wheelchair at night.

[0019] The upper shell 1 is provided with a control module for controlling various functions of the wheelchair. The control module includes a control panel 4, which is installed on the top of the upper shell 1. A power indicator light 10 is provided on the control panel 4. A speed indicator light 11 is provided on one side of the power indicator light 10. A power button 15 and a speed adjustment button 16 are installed on both sides of the speed indicator light 11. Function keys 17 are installed above the power button 15 and the speed adjustment button 16, and a horn key 18 is installed between the two function keys 17. A speaker 19 is provided at the bottom of the lower shell 6. The speaker 19 is connected to the control panel 4. When the horn key 18 is pressed, the control panel 4 will transmit the received signal to the speaker 19, causing the speaker 19 to emit a sound to warn pedestrians and remind them to pay attention to avoid. The surfaces of the power button 15, speed adjustment button 16, function keys 17 and horn key 18 are all provided with a luminous coating. The surfaces of the power button 15, speed adjustment button 16, function keys 17 and horn key 18 are all provided with corresponding labels. The labels are made of luminous coating. The labels absorb sunlight during the day and glow at night to facilitate the control of the electric wheelchair at night.

[0020] Preferably, a light intensity sensor 14 is connected to one side of the upper housing 1, and the control panel 4, LED light 12, and light intensity sensor 14 are all connected to the control box 7. An LED light strip 22 is installed between the upper housing 1 and the control panel 4. The light intensity sensor 14 can detect the light intensity in the environment. When the light intensity is low, the control panel 4 can control the LED light 12 to automatically turn on. The LED light 12 can also be turned on or off by pressing the function key 17.

[0021] Example 2

[0022] A further improvement on the basis of Example 1 is that Figure 4 The illustrated wheelchair controller with lighting has an upper shell 1 provided with a steering mechanism for adjusting the direction of the wheelchair. The steering mechanism includes an operating rod 13. An assembly hole 20 is provided on the upper shell 1. The operating rod 13 is installed in the assembly hole 20. A direction controller 21 is installed inside the lower shell 6. The bottom of the operating rod 13 is connected to the direction controller 21.

The bottom of the handle 3 is connected to a waterproof silicone sleeve 9. The outer wall of the waterproof silicone sleeve 9 is provided with a waterproof silicone ring 2. The bottom of the waterproof silicone ring 2 is connected to the top of the upper shell 1. The waterproof silicone sleeve 9 cooperates with the waterproof silicone ring 2 to protect the operating rod 13 and increase the service life of the operating rod 13. The direction controller 21 is connected to the steering bearing of the electric wheelchair. Adjusting the direction controller 21 by the handle 3 can adjust the direction of the wheelchair.

[0023] The process flow and working principle of the utility model are as follows: the light intensity sensor 14 on the upper shell 1 will monitor the light intensity in the environment around the electric wheelchair. When the wheelchair is used at night or in an environment with insufficient light, the control panel 4 will automatically turn on the LED light 12 at the end of the lower shell 6 according to the data monitored by the light intensity sensor 14, so as to illuminate the road in front of the wheelchair. There is no need to carry additional lighting tools, which is very convenient. The LED light 12 can be turned on or off by controlling the function key 17. Reflective strips 23 are installed on both sides of the lower shell 6. When there are pedestrians or vehicles on both sides, , a reflective strip 23 can be used to warn the user, prompting him to avoid it. The surfaces of the power button 15, speed adjustment button 16, function key 17 and horn key 18 are all provided with labels made of luminous coating, so that the power button 15, speed adjustment button 16, function key 17 and horn key 18 can glow in dim light. An LED light strip 22 is provided between the control panel 4 and the upper shell 1 to illuminate the control panel 4, making it easier for the user to accurately find and press the required control key in dim light, thereby improving the convenience and safety of using the electric wheelchair at night or in low-light environments.
