[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. 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.

[0034] 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.

[0035] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the structure of the wheelchair provided in an embodiment of this application. Figure 2 for Figure 1 A partial structural diagram of the wheelchair shown. Figure 3 for Figure 1 The diagram shows another part of the wheelchair's structure. This application provides a wheelchair 10, including a circuit board 100, two opposing armrests 200, a first electrical device 300, and a second electrical device 400. The first electrical device 300 is detachably mounted on either of the two armrests 200 and electrically connected to the circuit board 100; and the second electrical device 400 is detachably mounted on the other of the two armrests 200 and electrically connected to the circuit board 100.

[0036] The circuit board 100 is responsible for controlling and coordinating the various electronic functions of the wheelchair 10. The armrests 200 are components on the left and right sides of the wheelchair 10 used to support the user's arms, providing additional comfort and stability. The wheelchair 10 also includes a first electrical device 300 and a second electrical device 400, both of which can be detachably installed on either side of the armrests 200. When using the wheelchair 10, the user can comfortably rest their arms on the armrests 200 and directly operate either the first electrical device 300 or the second electrical device 400 without additional support or adjustment, thus improving user comfort.

[0037] Both the first electrical device 300 and the second electrical device 400 are connected to the circuit board 100 to realize their respective electronic functions and operation controls. Both the first electrical device 300 and the second electrical device 400 adopt a detachable design and can be flexibly installed on either of the two armrests 200. This allows users to freely exchange the installation positions of the first electrical device 300 and the second electrical device 400 between the two armrests 200 according to their usage habits and personal preferences, achieving a more comfortable and convenient operating experience. This is no longer limited by a fixed equipment layout, meets the personalized needs of users, and improves the applicability and flexibility of the wheelchair 10.

[0038] In some embodiments, please refer to Figure 4 and Figure 5 , Figure 4 for Figure 1 The diagram shows a partial structural representation of the wheelchair armrest. Figure 5 for Figure 1 The diagram shows a partial structural diagram of another armrest of the wheelchair. Each armrest 200 is provided with a first connection terminal 210 that is electrically connected to the circuit board 100; the first electrical device 300 includes a second connection terminal 310, which is electrically connected to the corresponding first connection terminal 210; the second electrical device 400 includes a third connection terminal 410, which is electrically connected to the corresponding first connection terminal 210.

[0039] Each armrest 200 is equipped with a first connection terminal 210 that is electrically connected to the circuit board 100. Simultaneously, the first electrical device 300 and the second electrical device 400 are respectively equipped with a second connection terminal 310 and a third connection terminal 410. Both the second connection terminal 310 and the third connection terminal 410 can be electrically connected to the first connection terminal 210 on either armrest 200. Therefore, both the second connection terminal 310 of the first electrical device 300 and the third connection terminal 410 of the second electrical device 400 can freely choose to connect to the first connection terminal 210 of either the left or right armrest 200. The universal design of the first connection terminal 210 gives users greater freedom in choosing the installation position of the first electrical device 300 and the second electrical device 400, allowing users to flexibly exchange the installation positions of the first electrical device 300 and the second electrical device 400 between the two armrests 200 according to their usage habits.

[0040] It should be noted that the position of the first connection terminal 210 can be freely adjusted within a certain range to accommodate the connection requirements after the first electrical device 300 and the second electrical device 400 have exchanged positions, ensuring that the second connection terminal 310 and the third connection terminal 410 can still be smoothly connected to the first connection terminal 210 after the position exchange. Moreover, the specific positions of the first connection terminal 210, the second connection terminal 310, and the third connection terminal 410 can be adjusted according to design requirements. This embodiment does not limit this, and the positions shown in the attached drawings are only examples.

[0041] In some embodiments, the first electrical device 300 further includes a joystick 320, which is electrically connected to the second connection terminal 310 and can drive the wheelchair 10 to move; the second electrical device 400 further includes a display screen 420, which is electrically connected to the third connection terminal 410 and can display images.

[0042] The first electrical device 300 includes a joystick 320, which is electrically connected to the circuit board 100 via a second connection terminal 310. This allows the user to control the wheelchair 10 to move forward, backward, and turn. The second electrical device 400 includes a display screen 420, which is electrically connected to the circuit board 100 via a third connection terminal 410. The display screen 420 provides the user with an intuitive visual interface, displaying key data such as speed, battery level, and navigation information.

[0043] In the design of a traditional wheelchair 10, the positions of the joystick 320 and the display screen 420 are often fixed, typically with the joystick 320 on one side and the display screen 420 on the other. This design is inconvenient for users with specific usage habits. For example, a right-handed user facing the joystick 320 on the left, or a left-handed user facing the joystick 320 on the right, will find it difficult to operate. However, based on the wheelchair 10 of this embodiment, right-handed users can choose to install the joystick 320 on the right armrest 200 and the display screen 420 on the left armrest 200, and left-handed users can choose to install the joystick 320 on the left armrest 200 and the display screen 420 on the right armrest 200. This allows users to easily control the joystick 320 while also easily viewing the information on the display screen 420.

[0044] For example, the first electrical device 300 includes an operating lever 320 and may also include a corresponding operating circuit board for processing various information inputs from the operating lever 320; the second electrical device 400 includes a display screen 420 and may also include a corresponding display circuit board for driving and controlling the display screen 420. The second connection terminal 310 of the first electrical device 300 may be disposed on the operating circuit board, and the third connection terminal 410 of the second electrical device 400 may be disposed on the display circuit board.

[0045] For example, the first electrical device 300 may also include a dust cover specifically designed to protect the operating lever 320 from dust and other impurities, thereby ensuring the cleanliness and proper operation of the operating lever 320.

[0046] It should be noted that this embodiment does not limit the specific devices of the first electrical device 300 and the second electrical device 400, nor does it limit the number of electrical devices. For example, it may also include a third electrical device. The third electrical device may be a massage device, which can also be designed to be detachably installed between any one of the two armrests 200. The massage device receives control commands and performs corresponding massage actions through its connection with the circuit board 100, providing users with a more comfortable riding experience.

[0047] Please combine Figure 6 , Figure 7 and Figure 8 , Figure 6 for Figure 2 The diagram shown partially conceals the structure of the first and second electrical devices. Figure 7 for Figure 1 The diagram shows the structure of the first electrical device for the wheelchair. Figure 8 for Figure 1 The diagram shows the structure of the second electrical device for the wheelchair. In some embodiments, each armrest 200 is provided with a mounting groove 220, and a first connecting end 210 is provided in the mounting groove 220; the first electrical device 300 also includes a first housing 330, an operating lever 320 is mounted on the first housing 330, the first housing 330 covers the corresponding mounting groove 220, and the first housing 330 smoothly transitions with the outer wall of the armrest 200; the second electrical device 400 also includes a second housing 430, a display screen 420 is mounted on the second housing 430, the second housing 430 covers the corresponding mounting groove 220, and the second housing 430 smoothly transitions with the outer wall of the armrest 200.

[0048] In this embodiment, each armrest 200 of the wheelchair 10 is designed with a mounting slot 220, which provides a mounting position for the first electrical device 300 and the second electrical device 400. The mounting slot 220 of each armrest 200 has a built-in first connection terminal 210, so that the second connection terminal 310 of the first electrical device 300 and the third connection terminal 410 of the second electrical device 400 can be connected to the first connection terminal 210 to achieve electrical connection with the circuit board 100 and realize their respective electronic functions.

[0049] The first electrical device 300 also includes a first housing 330, which is used to mount the operating lever 320 and covers and closes the corresponding mounting slot 220, effectively protecting the operating lever 320 and ensuring the safety of its electrical connections. The second electrical device 400 also includes a second housing 430, which is used to mount the display screen 420 and covers and closes the corresponding mounting slot 220, effectively protecting the display screen 420 and ensuring the safety of its electrical connections. Both the first housing 330 and the second housing 430 achieve a smooth transition at their joints with the outer wall of the handrail 200, improving the aesthetics and integrity of the handrail 200 structure and ensuring comfortable operation for the user.

[0050] Understandably, when it is necessary to exchange the positions of the first electrical device 300 and the second electrical device 400, it is essential to ensure that the entire assembly of the two devices is swapped accordingly. Specifically, the operating lever 320, operating circuit board, second connection terminal 310, and first housing 330 of the first electrical device 300 are moved to the original position of the second electrical device 400. Simultaneously, the display screen 420, display circuit board, third connection terminal 410, and second housing 430 of the second electrical device 400 are moved to the original position of the first electrical device 300. This ensures that every component of both the first and second electrical devices 300 is correctly installed in its new position and functions properly.

[0051] Please refer to Figure 9 , Figure 9 for Figure 7 The diagram shows a structural schematic of the first electrical device from another angle. In some embodiments, the first housing 330 has a rectangular opening 331, and the operating lever 320 is disposed within the opening 331 and is movable within the opening 331.

[0052] The first outer casing 330 has a rectangular opening 331, allowing the user to easily push or pull the control lever 320 forward, backward, left, right, and diagonally within the rectangular opening 331, thereby precisely controlling the wheelchair 10's forward, backward, and turning movements. In this embodiment, the opening 331 is designed in a rectangular shape, ensuring that the control lever 320 maintains a consistent or nearly consistent stroke component in all directions, including forward, backward, left, right, and diagonal operations. Taking a traditional circular opening 331 design as an example, when the control lever 320 rotates diagonally to the right, although both forward and rightward stroke components are generated simultaneously, due to the curvature of the circular opening, the forward stroke component when pushing diagonally to the right is smaller than the forward stroke when pushing directly forward. This difference may cause the user to experience a discontinuous or inconsistent acceleration experience during operation. In this embodiment, when the control lever is pushed diagonally to the right, it will also generate forward and rightward stroke components at the same time. Moreover, the forward stroke component generated is consistent with or nearly consistent with the forward stroke generated when it is pushed directly forward. Therefore, with the design of the rectangular opening 331, the control lever will not sacrifice forward speed when pushed diagonally, thus ensuring the continuity of operation and a relatively consistent acceleration experience.

[0053] Please continue to refer to this. Figure 1 , Figure 2 and Figure 3 In some embodiments, the wheelchair 10 also includes a seat 500, on which the circuit board 100 is mounted. Mounting the circuit board 100 on the seat 500 can effectively utilize the space of the wheelchair 10. The seat 500 is usually quite sturdy, and mounting the circuit board 100 inside the seat 500 can provide it with a certain degree of physical protection, reducing the risk of damage caused by impact or fall.

[0054] For example, the circuit board 100 can be mounted on the underside of the seat 500 and protected by a housing. The wheelchair 10 can have intelligent driving capabilities, and the circuit board 100 is the core of realizing this capability. It can be electrically connected to multiple intelligent driving modules, such as advanced sensors like TOF (Time of Flight) sensors integrated through electrical connections. These sensors can provide accurate environmental perception and distance measurement, enhancing the autonomous navigation and obstacle avoidance capabilities of the wheelchair 10.

[0055] Please refer to the reference. Figure 10 and Figure 11 , Figure 10 for Figure 3 The diagram shows the structure of the part and the wires. Figure 11 for Figure 1 The diagram shows another part of the wheelchair's structure. In some embodiments, the wheelchair 10 further includes a wire 600, which connects the circuit board 100 and the first connection terminal 210. The armrest 200 is provided with a wire groove 230, which accommodates the wire 600.

[0056] The first electrical device 300 and the second electrical device 400 are installed on the handrail 200. The second connection end 310 of the first electrical device 300 and the third connection end 410 of the second electrical device 400 are connected to the first connection end 210. The first connection end 210 is connected to the circuit board 100 through the wire 600, so that the first electrical device 300 and the second electrical device 400 are electrically connected to the circuit board 100 to realize their electronic functions.

[0057] The armrest 200 has a cable channel 230 inside to accommodate the cable 600, protect the cable 600 from external damage, and make the cable 600 layout neater and more orderly, so that no messy cables are visible from the outside, thus improving the overall aesthetics of the wheelchair 10.

[0058] In some embodiments, in order for the first electrical device 300 and the second electrical device 400 to communicate with the circuit board 100 even after the handrail 200 has been swapped, it is necessary to ensure the compatibility of the communication methods of the first connection terminal 210 and the wire 600 connected to the first electrical device 300 and the second electrical device 400. For example, the first electrical device 300 includes an operating lever 320, and the second electrical device 400 includes a display screen 420. The operating lever 320 can communicate with the circuit board 100 via CAN, and the display screen 420 can communicate with the circuit board 100 via CAN, USB, Ethernet, and other methods. To achieve communication compatibility, the wire 600 and the first connection terminal 210 can both be designed to be compatible with multiple communication methods such as CAN, USB, and Ethernet. In this way, regardless of whether the operating lever 320 or the display screen 420 is connected, communication with the circuit board 100 can be achieved through the connection of the first connection terminal 210 and the wire 600.

[0059] Furthermore, after the first electrical device 300 and the second electrical device 400 exchange positions on both sides of the handrail 200, effective communication between the first electrical device 300 and the second electrical device 400 and the circuit board 100 can be ensured through the following methods. For example, the wires 600 and connectors can be manually swapped. The circuit board 100 can be equipped with two connectors, such as a left connector and a right connector. After the positions are swapped, the wires 600 originally connected to the left connector can be moved to the right connector, and vice versa. By manually swapping the wires 600 and connectors, the correct matching of the wires 600 and connectors is ensured, so that even if the positions of the first electrical device 300 and the second electrical device 400 change, they can still communicate smoothly with the circuit board 100. Alternatively, software control can be used. The circuit board 100 can be equipped with a controller, which can control internal circuit switches to achieve communication between the first electrical device 300 and the second electrical device 400 after their positions are swapped. For example, an integrated connector can be used to combine two connectors into one. When the first power device 300 and the second power device 400 are swapped, the connection with the circuit board 100 will not be affected, and communication after the swap can still be achieved.

[0060] In some embodiments, the armrest 200 includes a support section 240, a middle section 250, and a connecting section 260. The support section 240 supports the arm, the connecting section 260 connects to the seat 500, and the middle section 250 connects the support section 240 and the connecting section 260. The middle section 250 is provided with a first receiving groove 251, and the connecting section 260 is provided with a second receiving groove 262. The second receiving groove 262 communicates with the first receiving groove 251 to form a groove 230.

[0061] The support section 240 of the armrest 200 supports the user's arm, providing a comfortable armrest experience. The connecting section 260 connects the armrest 200 to the wheelchair seat 500, ensuring the stability of the overall structure. The middle section 250 is located between the support section 240 and the connecting section 260, serving as a connection and transition. The first receiving groove 251 is located in the middle section 250, and the second receiving groove 262 is located in the connecting section 260. The first receiving groove 251 and the second receiving groove 262 are connected to form a continuous wire groove 230, which guides and protects the wire 600, allowing it to extend smoothly from the middle section 250 of the armrest 200 to the connecting section 260, maintaining the neatness and aesthetics of the armrest 200 while ensuring the safety of the wire 600.

[0062] In some embodiments, the seat 500 includes a seating portion 510 and two connecting portions 520. Each side of the seating portion 510 is connected to a connecting portion 520, and each armrest 200 is rotatably connected to a connecting portion 520. A first through hole 261 is provided on the side of the connecting segment 260 facing the connecting portion 520, and a second through hole 521 is provided on the side of the connecting portion 520 away from the other connecting portion 520. A wire 600 passes through the first through hole 261 and the second through hole 521.

[0063] The seat 500 includes a seating section 510 and two connecting sections 520. The seating section 510 is the main part for the user to sit on. The two connecting sections 520 are located on opposite sides of the seating section 510, connecting to the connecting section 260 of the armrest 200. The armrest 200 has a first through hole 261 on the side facing the connecting section 520, and the connecting section 520 has a second through hole 521 on the side facing the armrest 200. The first through hole 261 and the second through hole 521 correspond to each other, providing a safe and smooth passage for the cable 600. The cable 600 extends from the armrest 200 to the connecting section 520 through these two carefully designed through holes.

[0064] In some embodiments, the seating portion 510 includes a top plate 511 near the support section 240 and a fixing portion 512. The fixing portion 512 is disposed on the side of the top plate 511 away from the support section 240. One end of the connecting portion 520 extends into the seating portion 510 and is connected to the fixing portion 512. The fixing portion 512 is provided with a third through hole 513 on the side away from the top plate 511, and the wire 600 passes through the third through hole 513.

[0065] In this embodiment, the seating portion 510 includes a top plate 511 and a fixing portion 512. The top plate 511 is close to the support section 240 and can be the part that the user sits on directly. The fixing portion 512 is disposed on the side of the top plate 511 away from the support section 240. One end of the connecting portion 520 extends into the interior of the seating portion 510 and is connected to the fixing portion 512. On the side of the fixing portion 512 away from the top plate 511, a third through hole 513 is provided. The wire 600 passing through the second through hole 521 of the connecting portion 520 further passes through the third through hole 513 of the fixing portion 512, thereby realizing the electrical connection from the connecting portion 520 of the seat 500 to the interior of the seating portion 510.

[0066] For example, the first electrical device 300 and the second electrical device 400 can be installed on the support section 240 of the handrail 200 near the middle section 250. The second connection end 310 of the first electrical device 300 and the third connection end 410 of the second electrical device 400 are electrically connected to the first connection end 210 in the mounting groove 220. The first connection end 210 is further connected to the circuit board 100 through the wire 600. The following is the wiring process of the wire 600 from the handrail 200 to the inside of the seating part 510: The wire 600 starts at the middle section 250 of the handrail 200. The middle section 250 is provided with a first receiving groove 251 for initially receiving the wire 600. The connecting section 260 is provided with a second receiving groove 262. The second receiving groove 262 is connected to the first receiving groove 251 to form a wire groove 230. The wire 600 runs along this wire groove 230. The wire 600 extends smoothly from the middle section 250 to the connecting section 260. The connecting section 260 is rotatably connected to the connecting part 520 of the seat 500. The wire 600 continues to extend, passing through the first through hole 261 of the connecting section 260 and the corresponding second through hole 521 on the connecting part 520, realizing the smooth extension of the wire 600 from the armrest 200 to the connecting part 520. One end of the connecting part 520 extends into the interior of the seating part 510 and is connected to the fixing part 512. After passing through the second through hole 521 of the connecting part 520, the wire 600 continues to extend and further passes through the third through hole 513 of the fixing part 512, thereby ensuring that the wire 600 safely and stably enters the interior of the seating part 510, providing a connection path for the electrical connection between the first electrical device 300, the second electrical device 400 and the circuit board 100 installed in the seating part 510. In this embodiment, through holes are provided in the connecting section 260 of the armrest 200, the connecting part 520 of the seat 500, and the fixing part 512 of the seating part 510. This allows the wire 600 to be cleverly hidden in the internal structure by passing through these through holes, avoiding the clutter of external wiring and improving the overall aesthetics of the wheelchair 10. At the same time, the wire 600 is routed through the internal through holes, reducing damage to the wire 600 from external factors such as wear, compression, or environmental factors, thereby extending the service life of the wire 600.

[0067] In some embodiments, the seating portion 510 is provided with a limiting member 514, which is connected to a wire 600 to limit the wire 600.

[0068] In this embodiment, the seating part 510 is provided with one or more limiting members 514. The limiting members 514 can tightly clamp the wire 600 to ensure that it will not move or shake at will, and prevent the wire 600 from falling off or being damaged due to vibration or external force.

[0069] In some embodiments, there are multiple wires 600, and the wheelchair 10 also includes a sleeve 515, which houses multiple wires 600.

[0070] When multiple wires 600 need to pass from the armrest 200 area into the seating section 510, they can be grouped together and passed through the sleeve 515 to form a wiring harness. The sleeve 515 provides an extra layer of protection for the wires 600, preventing them from being physically damaged, such as worn or squeezed, when passing through the armrest 200 and seat 500, thus extending their service life. Furthermore, the sleeve 515 helps keep the wires 600 neat and orderly. Without the sleeve 515, multiple wires 600 might become tangled, forming a messy network of wires. This not only affects the aesthetics of the wheelchair 10 but may also increase the risk of short circuits or interference between the wires. The sleeve 515 neatly wraps the multiple wires 600 into a compact and orderly whole, saving space and significantly improving the neatness and safety of the wheelchair 10's internal structure.

[0071] Therefore, this embodiment cleverly uses a sleeve 515 to organize multiple wires 600 into an orderly wire bundle. The wire bundle is guided by the wire groove 230 inside the armrest 200 to ensure smooth and neat wiring. Subsequently, the wire bundle passes through the first through hole 261 of the armrest 200, the second through hole 521 of the connecting part 520, and the third through hole 513 inside the seating part 510. The design of these through holes allows the wire bundle to run along a predetermined path, avoiding messy wiring. During the wiring process, a limiting member 514 is also provided to firmly limit the wire bundle, thereby ensuring that the wires 600 are both safe and stable when transmitting signals, effectively extending the service life of the wires 600, and also improving the overall aesthetics of the wheelchair 10.
