Description

Technical Field

[0001] This application relates to the field of medical devices, specifically to a monitoring component and an electric wheelchair. Background Technology

[0002] As a medical device, wheelchairs are an important mobility tool widely used for home rehabilitation, transportation, medical treatment, or outdoor activities for the injured, sick, and disabled. They not only meet the mobility needs of people with limb disabilities and those with limited mobility, but also allow patients to use wheelchairs for rehabilitation training.

[0003] For ease of driving and safety, wheelchairs equipped with reversing assistance devices such as reversing radar or reversing cameras are used. Reversing radar uses ultrasonic sensors to receive reflected wave signals to detect obstacles; however, the driver cannot directly see the area behind the wheelchair, resulting in a poor driving experience. Reversing cameras provide a clear view of the area behind the wheelchair; however, these cameras require significant installation space and are not easily integrated into electric wheelchairs. Utility Model Content

[0005] To address the aforementioned problems, in a first aspect, this application provides a monitoring component, which includes a mounting plate, a camera module, and a lighting module, wherein the lighting module includes at least one of a brake light and a fill light; the camera module and the lighting module are spaced apart on the mounting plate.

[0006] Optionally, the lighting module includes the brake light or the supplementary light; the mounting plate includes a first mounting part and a second mounting part that are bent and connected, the camera module is disposed in the first mounting part, and the lighting module is disposed in the second mounting part.

[0013] The monitoring component further includes at least one of a binocular camera module and a time-of-flight sensor, wherein at least one of the binocular camera module and the time-of-flight sensor is disposed in the second mounting part or in the housing.

[0014] Optionally, the monitoring component further includes a housing, and the mounting plate is disposed within the housing; wherein,

[0015] The monitoring component also includes a cover plate, which is movable relative to the housing and used to switch between a first state and a second state. In the first state, the cover plate is used to block the camera module; in the second state, the cover plate is used to be offset from the camera module.

[0016] Optionally, the housing is provided with a limiting member, and the cover plate is provided with a first limiting part and a second limiting part. When the cover plate moves to the point where the first limiting part is limited and connected with the limiting member, the cover plate is in the first state; when the cover plate moves to the point where the second limiting part is limited and connected with the limiting member, the cover plate is in the second state.

[0037] The following will refer to the appendices in this application. Figure 1 To be continued Figure 9 The technical solutions in this application are clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0038] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0039] In the field of wheelchairs, wheelchairs are electrically powered, equipped with batteries that provide the energy for movement. Users control the electric wheelchair by inputting driving commands via joysticks or a touchscreen to move it forward, backward, and turn. However, reversing assistance devices for electric wheelchairs, such as reversing radar, cannot directly obtain images of the road surface, and reversing cameras are bulky and produce unclear images or have unsuitable field of view. Therefore, these reversing assistance devices suffer from drawbacks such as poor driving experience or being too bulky for easy installation.

[0040] To address the aforementioned technical problems, this application provides a monitoring component 100 and an electric wheelchair 10. The monitoring component 100 mounts a camera module 120 and a lighting module 130 on the same mounting plate 110. The camera module 120 can capture images of the road surface, improving driving safety and convenience. The camera module 120 and the lighting module 130 are more easily assembled onto the electric wheelchair 10 via the mounting plate 110, improving the installation convenience of the monitoring component 100.

[0041] It is understood that the monitoring component 100 of this application can be used not only in electric wheelchairs 10, but also in mobile devices such as strollers, bicycles, electric vehicles, motorcycles, and scooters.

[0042] The following detailed description is based on specific embodiments. It should be noted that the embodiments of this application can be presented in various forms, and some examples will be described below.

[0043] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a first structure of the monitoring component 100 provided in an embodiment of this application. Figure 2 This is a partial cross-sectional view of a monitoring component 100 provided in an embodiment of this application. The monitoring component 100 is applied to an electric wheelchair 10. The monitoring component 100 includes a mounting plate 110, a camera module 120, and a lighting module 130. The lighting module 130 includes at least one of a brake light 131 and a supplementary light 132. The camera module 120 and the lighting module 130 are disposed at a distance from each other on the mounting plate 110.

[0044] It is understood that the camera module 120 is capable of capturing image or video information. In some embodiments, the camera module 120 includes a camera sensor, a lens, an image signal processor, a memory, and other structures. The camera sensor is used to capture light and convert it into electrical signals. The lens is mounted in front of the camera sensor and used to focus the light. The image signal processor is used to process the raw image data captured by the camera sensor and to generate a high-quality image. The memory is used to temporarily store the image data until the data is written to a permanent storage device or transmitted wirelessly. The camera module 120 may be a front-facing camera module, a rear-facing camera module, an infrared camera module, a fisheye camera module, a stereo camera module, etc.

[0045] It is understood that the lighting module 130 may include either a separate brake light 131 or a supplementary light 132, or both. In some examples, the brake light 131 includes a bulb, a switch, optical components such as a corner reflector, and circuit components. The brake light 131 is used to provide illumination, warning, and indication functions for the electric wheelchair 10. For example, the brake light 131 has a brake warning function, illuminating when the driver presses the brake pedal to remind vehicles and pedestrians behind to slow down. Another example is that the brake light 131 has a turn signal function, providing a turn indication signal when the electric wheelchair 10 turns. Yet another example is that the brake light 131 has a taillight illumination function, illuminating at night or in low-light environments. It should be noted that the brake light 131 in this application may be a lamp structure with one, two, or three of the aforementioned brake warning, turn indication, and taillight illumination functions. This application does not limit the specific structure of the brake light 131.

[0046] It is understood that the supplementary light 132 is an illumination structure used to supplement light. Exemplarily, in some embodiments, the supplementary light 132 includes a light source that remains constantly lit after the mobile device is powered on; in other embodiments, the supplementary light 132 includes a light source, a controller, an environmental sensor, a control chip, and other structures. The supplementary light 132 typically uses LED beads as the light source. The controller is used to adjust the brightness and color temperature of the light. The environmental sensor is used to detect parameters such as ambient light and temperature in real time. The control chip is responsible for receiving sensor data and automatically adjusting parameters such as the brightness and color temperature of the light source according to an algorithm. The supplementary light 132 can illuminate the camera module 120 to improve the clarity of the images captured by the camera module 120. In some examples, the supplementary light 132 can be selected according to the type of camera module 120 to further improve the imaging effect of the camera module 120 in low light conditions. For example, if the camera module 120 is an infrared camera module, then the supplementary light 132 can be an infrared supplementary light.

[0047] It is understood that the mounting plate 110 has a plate-like structure. The mounting plate 110 can be a regular plate-like structure or an irregularly shaped plate-like structure. The mounting plate 110 is used to support the camera module 120 and the lighting module 130. The camera module 120 and the lighting module 130 can be fixed to the mounting plate 110 by means of fixed connection, fixed welding, limiting snap-fit, magnetic attraction, etc. Among them, the camera module 120 and the lighting module 130 can be disposed on the same side or different sides of the mounting plate 110, or, some structures of the camera module 120 and the lighting module 130 are located on the same side. This application does not limit the specific manner in which the camera module 120 and the lighting module 130 are disposed on the mounting plate 110.

[0048] It is understandable that, such as Figure 1 and Figure 2 As shown, the monitoring component 100 also includes a housing 140. A mounting plate 110, a camera module 120, and a lighting module 130 are all located within the housing 140. The mounting plate 110 is fixedly connected to the housing 140. The housing 140 is used to connect with other structures of the electric wheelchair 10, thus allowing the monitoring component 100 to be assembled onto the electric wheelchair 10 via the mounting plate 110 and the housing 140. The housing 140 has through-holes for the camera module 120 to collect light, or for the brake lights 131 to provide illumination, warning, and indication functions.

[0049] The camera module 120 of the monitoring component 100 in this application embodiment can capture images of the road environment, improving driving safety and convenience. Meanwhile, both the camera module 120 and the lighting module 130 are mounted on the mounting plate 110, integrated into the same mounting plate 110. On the one hand, the camera module 120 and the lighting module 130 occupy less space, making it easier to miniaturize the monitoring component 100; on the other hand, compared to the solution where the camera module 120 and the lighting module 130 are each installed separately on the electric wheelchair 10, the camera module 120 and the lighting module 130 of this application are more easily assembled into the electric wheelchair 10 via the mounting plate 110, improving the installation convenience of the monitoring component 100. Furthermore, when the lighting module 130 includes a brake light 131, the brake light 131 can realize the functions of lighting, warning, and indication for the electric wheelchair 10, thus expanding the functions of the monitoring component 100; when the lighting module 130 includes a supplementary light 132, the supplementary light 132 can supplement the light for the camera module 120, making the images captured by the camera module 120 clearer and further improving the shooting performance of the monitoring component 100.

[0050] In some examples, when the lighting module 130 includes a brake light 131 or a fill light 132, please refer to... Figure 3 , Figure 3This is a schematic diagram of a first structure of the mounting plate 110 of the monitoring component 100 provided in this application embodiment. The mounting plate 110 includes a first mounting portion 111 and a second mounting portion 112 that are bent and connected. The camera module 120 is disposed in the first mounting portion 111, and the light module 130 is disposed in the second mounting portion 112.

[0051] It is understandable that the first mounting portion 111 and the second mounting plate 110 are not on the same plane, thus forming an angle between them. In some examples, the first mounting portion 111 is perpendicular to the second mounting portion 112, making the angle between them a right angle. In this case, the two vertically arranged mounting portions are more regular, and the first mounting portion 111 and the second mounting portion 112 are easier to fix onto the housing 140. In other examples, the first mounting portion 111 may also be outwardly extended relative to the second mounting portion 112, making the angle between them an obtuse angle. In this case, the space between the two mounting portions is larger, which facilitates the installation of structures such as the camera module 120 and the lighting module 130. Of course, in other examples, the angle between the first mounting portion 111 and the second mounting portion 112 may also be an acute angle. The embodiments of this application do not limit the specific shape of the two mounting portions.

[0052] It is understandable that the camera module 120 and the lighting module 130 can be connected to the same side or different sides of the two mounting portions. For example, when the lighting module 130 includes a brake light 131, the camera module 120 can be positioned on one side of the first mounting portion 111 and collect image information of the outside of the monitoring component 100 through the through-hole on the housing 140. The brake light 131 can be positioned on the side of the second mounting portion 112 opposite to the camera module 120 and perform functions such as illumination, warning, and indication through the through-hole of the housing 140. In this case, since the camera module 120 and the brake light 131 are located on different sides, the light emitted by the brake light 131 is less likely to be captured by the camera module 120 and cause interference, the image information captured by the camera module 120 is more realistic and accurate, and the shooting performance of the camera module 120 is better. For example, when the lighting module 130 includes a fill light 132, the camera module 120 and the fill light 132 can be respectively disposed on the same side of the first mounting part 111 and the second mounting part 112. In this case, the distance between the camera module 120 and the fill light 132 is relatively close, which makes it convenient for the fill light 132 to provide light compensation for the camera module 120.

[0053] The mounting plate 110 in this embodiment includes a first mounting portion 111 and a second mounting portion 112 that are bent. The length of the two bent mounting portions is small, and the mounting plate 110 occupies less space in the length direction, enabling the monitoring component 100 to be miniaturized and easier to assemble onto the electric wheelchair 10. Furthermore, when the camera module 120 and the brake light 131 are located on opposite sides of the two bent mounting portions, the interference between the camera module 120 and the brake light 131 is less, resulting in better image quality from the camera module 120. When the camera module 120 and the supplementary light 132 are located on the same side of the two bent mounting portions, the supplementary light 132 can better provide light compensation for the camera module 120, further improving the shooting performance of the camera module 120.

[0054] In some examples, when the lighting module 130 includes both a brake light 131 and a fill light 132, please refer to... Figure 4 , Figure 4 This is a second structural schematic diagram of the mounting plate 110 of the monitoring component 100 provided in this application embodiment. The mounting plate 110 includes a first mounting portion 111, a second mounting portion 112, and a third mounting portion 113. The first mounting portion 111 and the third mounting portion 113 are respectively bent and connected to both sides of the second mounting portion 112, and the first mounting portion 111 and the third mounting portion 113 extend in opposite directions. For example, the first mounting portion 111 extends downward toward the second mounting portion 112, and the third mounting portion 113 extends upward toward the second mounting portion 112. In this case, the camera module 120 is disposed on the first mounting portion 111, the supplementary light 132 is disposed on the second mounting portion 112, and the brake light 131 is disposed on the third mounting portion 113.

[0055] In this embodiment, the first mounting portion 111, the second mounting portion 112, and the third mounting portion 113 of the mounting plate 110 form a double-bending structure. The double-bending mounting plate 110 has a smaller length dimension, and the monitoring component 100 occupies less space. At the same time, the two mounting portions extending in opposite directions allow the camera module 120 and the brake light 131 to make more efficient use of the space above and below the second mounting portion 112, improving the space utilization rate of the monitoring component 100. Moreover, the camera module 120 and the brake light 131 are respectively disposed in the first mounting portion 111 and the third mounting portion 113, and the distance between the camera module 120 and the brake light 131 is relatively large, so the light emitted by the brake light 131 is less likely to interfere with the camera module 120. Meanwhile, the camera module 120 and the supplementary light 132 are respectively disposed in the first mounting portion 111 and the third mounting portion 113, and the distance between the supplementary light 132 and the camera module 120 is relatively small, so the supplementary light 132 can better illuminate the camera module 120.

[0056] In some examples, the first mounting portion 111 is bent relative to the second mounting portion 112, and the first included angle formed between them can be, but is not limited to, an obtuse angle. For example, the first included angle is greater than or equal to 110 degrees and less than 180 degrees. Further, the first included angle is approximately 110 degrees, 120 degrees, 150 degrees, or 170 degrees. Since the first included angle between the two mounting portions is an obtuse angle, when the camera module 120 is disposed on the first mounting portion 111 and the supplementary light 132 is disposed on the second mounting portion 112, the camera module 120 has a larger field of view, the supplementary light 132 can more easily provide light to the camera module 120, and at the same time, the light emitted by the supplementary light 132 is less likely to directly enter the camera module 120, avoiding glare and overexposure of the camera module 120. The camera module 120 can capture clearer road images, and the imaging effect of the camera module 120 is better. Of course, in other examples, the first mounting part 111 may also be on the same plane as the second mounting part 112, such that the included angle between the first mounting part 111 and the second mounting part 112 is 180 degrees.

[0057] In some examples, the third mounting portion 113 is bent relative to the second mounting portion 112, and the second included angle formed between them may be, but is not limited to, a right angle. For example, the third mounting portion 113 is arranged perpendicularly to the second mounting portion 112, and the two vertically arranged mounting portions are easier to connect to the housing 140, and thus easier to assemble onto the electric wheelchair 10.

[0058] In some examples, please refer again. Figure 3 and Figure 4 The mounting plate 110 can be designed with a hollowed-out shape. At least one of the first mounting portion 111, the second mounting portion 112, and the third mounting portion 113 is provided with a clearance hole 114 for avoiding components. For example, the second mounting portion 112 is provided with a clearance hole 114 for avoiding components of the supplementary light 132 and for avoiding the cover plate 150 mentioned later. As another example, the third mounting portion 113 is provided with a clearance hole 114 for avoiding components of the brake light 131. In this embodiment of the application, the clearance hole 114 is provided on the mounting plate 110, which not only allows for better placement of components such as the supplementary light 132 and the brake light 131, but also achieves a compact design of various components and completes the avoidance of various components, thereby improving the space utilization of the monitoring component 100.

[0059] In some examples, the mounting plate 110 can be a metal plate. For example, the mounting plate 110 is a heat spreader, which can efficiently and evenly distribute heat in a low-temperature manner, avoiding local overheating, and has higher heat dissipation efficiency.

[0060] In some examples, please refer again. Figure 1 , Figure 2 Please refer to Figure 5and Figure 6 , Figure 5 This is a first connection diagram of the privacy cover of the monitoring component 100 provided in this application embodiment. Figure 6 This is a second connection diagram of the privacy cover of the monitoring component 100 provided in this application embodiment. The monitoring component 100 also includes a cover plate 150, which is movable relative to the housing 140 and used to switch between a first state and a second state. In the first state, the cover plate 150 is used to block the camera module 120; in the second state, the cover plate 150 is set separately from the camera module 120.

[0061] It is understood that the cover plate 150 is movably connected to the housing 140. For example... Figure 1 and Figure 5 As shown, in the first state, the cover plate 150 moves to the front of the camera module 120, covering the lens of the camera module 120 and preventing the lens from acquiring external environmental information of the monitoring component 100, thus the camera module 120 does not acquire external environmental image information. At this time, the monitoring component 100 and the electric wheelchair 10 can adapt to scenarios requiring privacy protection or confidentiality. The monitoring component 100 and the electric wheelchair 10 can also adapt to scenarios where a caregiver pushes the electric wheelchair 10 and does not need to acquire road environment images.

[0062] It is understandable that, such as Figure 6 As shown, in the second state, at least a portion of the cover plate 150 can also move into the housing 140 so that the cover plate 150 and the camera module 120 are staggered. At this time, the cover plate 150 does not affect the normal operation of the camera module 120, and the camera module 120 can normally acquire road environment information to improve the driving convenience of the driver's license.

[0063] It is understood that the cover plate 150 can switch between a first state and a second state under the drive of a driving mechanism, which may be, but is not limited to, a motor. Of course, the cover plate 150 can also be manually driven by the user to switch between the first and second states. The cover plate 150 of this application can switch states both linearly and by rotation. This application does not limit the driving or movement form of the cover plate 150.

[0064] The cover plate 150 in this embodiment can either block the camera module 120 or be positioned offset from it. The camera module 120 can either function normally to provide road environment information to the monitoring component 100 and the electric wheelchair 10, or it can choose not to acquire road environment information to protect privacy. With the cover plate 150, the monitoring component 100 and the electric wheelchair 10 of this application can adapt to more application scenarios, thus expanding their applications.

[0065] Please refer to the following: Figure 7 , Figure 7 This is a third connection diagram of the privacy cover of the monitoring component 100 provided in this application embodiment. In some examples, the housing 140 is provided with a limiting member 141, and the cover plate 150 is provided with a first limiting part 151 and a second limiting part 152. When the cover plate 150 moves to the point where the first limiting part 151 is limited to the limiting member 141, the cover plate 150 is in a first state; when the cover plate 150 moves to the point where the second limiting part 152 is limited to the limiting member 141, the cover plate 150 is in a second state.

[0066] It is understood that the limiting member 141 of the housing 140 can, but is not limited to, achieve a limiting connection with the first limiting part 151 and the second limiting part 152 through means such as snap-fit, magnetic attraction, or abutment. Figure 7 As shown, in some examples, the limiting member 141 is a spring-loaded structure, such as an arched spring-loaded structure; the first limiting part 151 and the second limiting part 152 are groove structures. When the spring-loaded structure is in its initial state and is limited within the groove structure of the first limiting part 151, the cover plate 150 is in the first state and blocks the camera module 120. When the cover plate 150 slides upward along the direction from the second limiting part 152 to the first limiting part 151, the spring-loaded structure disengages from the first limiting part 151 under elastic force until the spring-loaded structure is engaged in the groove structure of the second limiting part 152 and is limited again. At this time, the cover plate 150 is in the second state and is offset from the camera module 120. For example, Figure 7 As shown, the edges of the groove structures of the first limiting part 151 and the second limiting part 152 are arc-shaped structures. The arc-shaped structure can play a guiding role so that the spring structure can be more smoothly detached from the groove structure.

[0067] It should be noted that the limiting member 141, the first limiting part 151, and the second limiting part 152 can also be other structures. Any structure that can achieve a limiting connection is within the protection scope of the embodiments of this application.

[0068] In this embodiment, the cover plate 150 is provided with two limiting portions, and the housing 140 is provided with a limiting member 141. Regardless of whether it is in the first state or the second state, the cover plate 150 can be fixed relative to the housing 140. The cover plate 150 can maintain its current state and is not easily changed, making the state of the cover plate 150 more stable. Furthermore, when the limiting member 141 is a spring sheet structure and the two limiting portions are groove structures, the limiting and releasing of the cover plate 150 is achieved through elastic force, making the structure of the limiting member 141 and the limiting portions simpler.

[0069] Please refer to this again. Figure 1 In some examples, the monitoring component 100 also includes at least one of a binocular camera module 160 and a time-of-flight sensor 170, wherein at least one of the binocular camera module 160 and the time-of-flight sensor 170 is disposed in the second mounting portion 112 or in the housing 140.

[0070] Understandably, the binocular camera module 160 includes two cameras that capture images of the scene from different angles. The binocular camera module 160 uses the differences between these images to calculate the distance and depth information of objects, thereby achieving three-dimensional perception of the objects. The time-of-flight sensor 170, also known as a TOF (Time-of-Flight) sensor, is a sensor structure that uses the time of flight of light, sound waves, or other forms of signals to measure the distance between a target object and the sensor. A TOF sensor includes at least a signal transmitter and a signal receiver. The signal transmitter module sends a light pulse, sound wave, or other form of signal. This signal is reflected when it encounters the target object and received by the signal receiver module. The distance to the target object can be calculated based on the round-trip time and a calculation formula.

[0071] Understandably, the second mounting portion 112 of the mounting plate 110 can be lengthened; for example, the second mounting portion 112 can be increased in size along the extension direction of the third mounting portion 113. In some examples, the two cameras of the binocular camera module 160 can be respectively disposed at both ends of the second mounting portion 112. In other examples, the signal transmitting module and signal receiving module of the TOF sensor can be respectively disposed at both ends of the second mounting portion 112. Simultaneously, two through holes can be correspondingly provided on the housing 140 to facilitate the binocular camera module 160 in acquiring light, or to facilitate the time-of-flight sensor 170 in transmitting and receiving signals.

[0072] Understandably, in other examples, the binocular camera module 160 and the time-of-flight sensor 170 may also be mounted on the housing 140.

[0073] It is understood that the monitoring component 100 in this application embodiment may include either a binocular camera module 160 or a time-of-flight sensor 170, or the monitoring component 100 may include both a binocular camera module 160 and a time-of-flight sensor 170.

[0074] The monitoring component 100 of this application embodiment is provided with at least one of a binocular camera module 160 and a time-of-flight sensor 170. The binocular camera module 160 can realize three-dimensional perception of objects, and the time-of-flight sensor 170 can detect the distance of the target object. Thus, the monitoring component 100 has a stronger perception of the surrounding environment and can adapt to the intelligent driving blind spot filling needs of the electric wheelchair 10.

The network interface is used to connect a network cable or telephone line to enable the monitoring component 100 and the electric wheelchair 10 to network or make phone calls. The joystick interface is used to connect a joystick, which the user can use to control the walking status of the electric wheelchair 10.

[0077] It is understood that one or more expansion interfaces 180 may be provided on the housing 140. Multiple expansion interfaces 180 can be used to implement the same function; or, multiple expansion interfaces 180 can be used to implement different functions; or, some expansion interfaces 180 can be used to implement the same function, and other expansion interfaces 180 can be used to implement different functions. The specific type of expansion interface 180 is not limited in the embodiments of this application.

[0078] In this embodiment of the application, an expansion interface 180 is provided on the housing 140 of the monitoring component 100, which can expand the functions of the monitoring component 100 and the electric wheelchair 10, and improve the functional diversity of the monitoring component 100 and the electric wheelchair 10.

[0079] Based on the structure of the monitoring component 100 described above, please refer to... Figure 9 , Figure 9This is a schematic diagram of the structure of an electric wheelchair 10 provided in an embodiment of this application. The electric wheelchair 10 includes the monitoring component 100 of any of the above embodiments, and the electric wheelchair 10 also includes a display 200, which is used to display image information acquired by the camera module 120 of the monitoring component 100.

[0080] Understandably, in some examples, the display 200 can be electrically connected to the camera module 120 to acquire and display the image information transmitted by the camera module 120. Of course, in other examples, both the display 200 and the camera module 120 can be electrically connected to the controller of the electric wheelchair 10, with the camera module 120 transmitting image information to the controller, and the controller transmitting that image information to the display 200. The driver can then visually view images of the road environment through the display 200.

[0081] Understandably, the lighting module 130 of the monitoring component 100 (e.g., supplementary light 132, brake light 131) can also be connected to the controller of the electric wheelchair 10 to receive control from the controller.

[0082] Understandably, in some examples, the electric wheelchair 10 also includes a seat 300, a display 200 disposed on the front side of the backrest of the seat 300, and a monitoring component 100 disposed on the rear side of the backrest of the seat 300. For example, the display 200 may be disposed on the armrest of the seat 300, and the monitoring component 100 may be disposed on the back of the backrest of the seat 300. In this case, the camera module 120 of the monitoring component 100 is a rear-facing camera module, used to capture reversing images, and the supplementary light 132 is used to illuminate the camera in the dark.
