Description

Technical Field

[0001] This invention relates to the field of intelligent wheelchair technology, specifically to an intelligent wheelchair. Background Technology

[0002] As a rehabilitation tool for patients, intelligent wheelchairs are an effective means of transportation for people with limb disabilities. With the continuous advancement of intelligent diagnosis and treatment technology, intelligent wheelchairs, through the combination of online and offline technologies, are being widely used in various rehabilitation stages.

[0003] For example, a smart wheelchair, as disclosed in patent CN208301812U, includes a chassis, a seat mounted on the chassis, and a front wheel frame and a rear wheel frame respectively mounted at the front and rear ends of the chassis. The rear end of the chassis is provided with two first hinge parts and two second hinge parts, and the rear wheel frame is provided with two third hinge parts and two fourth hinge parts. The two third hinge parts are respectively hinged to the two first hinge parts, the two fourth hinge parts are respectively hinged to one end of a buffer member, and the two second hinge parts are respectively hinged to the other end of the two buffer members. The chassis of the smart wheelchair has shock absorption performance, which can improve the comfort of the smart wheelchair when it is in motion.

[0004] For example, patent CN209662012U describes an intelligent wheelchair, including a seat plate. The bottom of the seat plate has a universal moving mechanism, which includes a universal ball and at least three driving devices. Each driving device is in contact with the universal ball and collectively drives the universal ball to roll. By controlling the rotational speed of the three driving devices, the universal ball can be driven to roll in the direction of the resultant force of the three driving devices, thereby moving the intelligent wheelchair in that direction. The universal ball is spherical and can roll in any direction, allowing the intelligent wheelchair to move in any direction, making it more agile.

[0005] For example, the patented smart wheelchair with announcement number CN222172490U includes a frame, a seat located above the frame, and a chassis located below the frame. The smart wheelchair also includes a first laser sensor and a three-dimensional image sensor. The first laser sensor is located below the chassis, and the three-dimensional image sensor is located on the armrest. The detection direction of the first laser sensor is towards the forward direction, the left translation direction, and the right translation direction of the smart wheelchair, and the detection direction of the three-dimensional image sensor is towards the forward direction of the smart wheelchair. The three-dimensional image sensor and the first laser sensor are used to detect obstacles in front, avoiding the safety hazards caused by relying solely on the user to find the way and avoid obstacles.

[0006] Most of the aforementioned existing technologies improve the overall structure. However, most existing smart wheelchairs are in a fixed transmission state during use. When the user encounters external forces that cause tilting or skew during climbing, they cannot effectively maintain their center of gravity, making them prone to tipping over and other dangerous situations. Especially when encountering obstacles in blind spots, the tires may come into contact with protruding objects, causing the wheelchair to tilt at a large angle. As the user's center of gravity shifts and is subjected to lateral pressure, there is a significant risk of instability, thus limiting their usability. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent wheelchair to solve the problem mentioned in the background art that when the user is exposed to external forces causing tilting or skew during climbing, the wheelchair cannot effectively maintain its overall center of gravity, which leads to dangerous situations such as tipping over. In particular, when encountering obstacles in the blind spot, the tires may come into contact with protruding objects, causing the wheelchair to tilt at a large angle. As the user's center of gravity shifts, it poses a significant risk of instability.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an intelligent wheelchair, comprising a wheelchair body, an external wheel assembly mounted on the outer side of the wheelchair body, and a seat assembly disposed in the middle of the wheelchair body; a counterweight assembly nested and connected to the lower end of the seat assembly, and a movable guide component nested and mounted on the lower end face of the seat assembly, with a return spring fixedly connected to the outer side of the movable guide component, and the return spring and the lower end of the seat assembly being mutually connected; a connecting connector is connected to the shaft end of the external wheel assembly, and the connecting connector is rotatably connected to the wheelchair body; an adaptive center of gravity adjustment mechanism is provided between the external wheel assembly and the seat assembly, and the overall tilt state of the wheelchair body is controlled by the adaptive center of gravity adjustment mechanism.

[0009] Furthermore, the adaptive center of gravity adjustment mechanism is provided with a contact switch assembly, which is mated to the surface of the movable guide and the seat assembly. A reserved electric push rod is installed inside the side end of the wheelchair body, and the reserved electric push rod is electrically connected to the contact switch assembly. The reserved electric push rod is powered by a reserved battery.

[0010] Furthermore, a nested fitting component is nested inside the edge of the wheelchair body, and a guide connector is connected to the lower end of the nested fitting component. Magnets are fixedly connected to the outer sides of both the guide connector and the connecting connector. A built-in reserved liquid bladder is bonded to the upper end of the nested fitting component, and the built-in reserved liquid bladder is located on the inner side of the edge of the wheelchair body.

[0011] Furthermore, when the reserved electric push rod receives an electrical signal from two sets of contact switch assemblies that are in contact with each other, it drives its output end to move downward, and the reserved electric push rod disengages from the limiting state between itself and the docking connector, and the docking connector rotates along the inner side of the wheelchair body.

[0012] Furthermore, during the upward rotation of the docking connector, pressure is simultaneously applied to the contacting guide connector, and the guide connector drives the upper nested fitting component to move in position simultaneously, and the nested fitting component forms a pressed state on the contacting built-in reserved liquid bladder.

[0013] Furthermore, the seat assembly has an inner side with a movable support structure that adaptively adjusts the occupant's center of gravity. The movable support structure has a supply pipe located inside the built-in pre-reserved liquid bladder and extends along the inner side of the wheelchair body. The surface of the seat assembly has an external pre-reserved liquid bladder connected to the supply pipe.

[0014] Furthermore, the built-in pre-reserved liquid bladder supplies liquid to the external pre-reserved liquid bladder at the end through the supply tube, and the expansion of the external pre-reserved liquid bladder provides support and guidance for the user's buttocks.

[0015] Furthermore, the adaptive center of gravity adjustment mechanism is also provided with a first liquid bladder component, which is located inside the seat assembly. The movable guide has a protruding structure on its exterior, and the outer sides of the first liquid bladder component and the movable guide correspond to each other. The inner side of the first liquid bladder component is connected to a supply hose, which runs through the inner side of the wheelchair body. A limiting docking component is nested inside the inner side of the wheelchair body, and the upper end of the limiting docking component is fixedly connected to a spring component that docks with the inner side of the wheelchair body. The outer side of the limiting docking component is connected to a second liquid bladder component, and the second liquid bladder component is connected to the supply hose.

[0016] Furthermore, during the outward movement of the movable guide, pressure is applied to the first liquid bladder component in contact, and the first liquid bladder component supplies work to the inside of the second liquid bladder component through the supply hose. The second liquid bladder component pushes the outer limiting docking component to move downward along the inner side of the wheelchair body until the limiting docking component disengages from the limiting state between itself and the docking connector.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This intelligent wheelchair is equipped with an adaptive center of gravity adjustment mechanism. During movement, the wheelchair body, in conjunction with the always vertically downward counterweight component at the bottom, effectively maintains its center of gravity. When the user is subjected to external force causing tilting or leaning during climbing, the seat component at the corresponding tilt angle will be resisted by the counterweight component with its vertical center of gravity pointing downward, simultaneously applying pressure to the corresponding movable guide component. When the reserved electric push rod receives an electrical signal from two sets of contact switch components, it will drive its output end to move downward, allowing the reserved electric push rod to disengage from the limiting state between itself and the docking connector. At this time, the docking connector connected to the external wheel assembly will rotate upward along the outer side of the wheelchair body according to the tilt state of the wheelchair body, thereby creating a reverse support effect for the tilted wheelchair body. In conjunction with the counterweight component, the center of gravity is changed, controlling and adjusting the overall balance of the wheelchair to prevent dangerous situations such as tipping over.

[0019] Furthermore, the overall electric push rod is designed to record data via a preset Bluetooth output during reciprocating drive. If the number of drives exceeds a certain limit in a single period, a signal will be transmitted to the user's family member's mobile phone to remind them to accompany or observe the user in a timely manner. This helps to prevent adverse effects caused by excessively bumpy roads, thus enabling effective online and offline intelligent diagnosis and treatment.

[0020] Furthermore, an active support structure is provided. During the upward movement of the docking connector under force, its upper end will simultaneously apply pressure to the contacting guide connector, thereby causing the guide connector to drive the upper nested fitting part to move upward to the contacting built-in reserved liquid bladder. This allows the pressurized built-in reserved liquid bladder to supply fluid to the external reserved liquid bladder at the end through the supply pipe. The external reserved liquid bladder will then expand and support the user's buttocks along the bottom of the seat assembly, prompting the user to move in time to the opposite position of the side-tipping state. Even when encountering obstacles in the blind spot or when the tires contact the protruding object and the wheelchair tilts at a large angle, the center of gravity of the user is prevented from shifting and causing lateral pressure, ensuring the safety of use.

[0021] Furthermore, another transmission method with an adaptive center of gravity adjustment mechanism is provided. During the outward movement of the movable guide member, it will apply pressure to the contacting first liquid bladder member through the outer protrusion. The first liquid bladder member will then supply the second liquid bladder member through the supply hose, thereby causing the second liquid bladder member to push the outer limiting docking member downward along the inner side of the wheelchair body until the limiting docking member disengages from the limiting state between itself and the docking connector. At this time, the docking connector connected to the external wheel assembly will simultaneously disengage from the limiting state, thereby effectively performing the reverse support work for the side-tilting state of the external wheel assembly. After disengaging from the force state, the docking connector will then be reset through the corresponding spring assembly to ensure its operational practicality. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figure 1 and Figures 3-10 To address the technical problem of the inability to effectively maintain the overall center of gravity when a user is exposed to external forces causing tilting or leaning during climbing, thus leading to dangerous situations such as tipping over, this invention provides the following technical solution: An intelligent wheelchair, comprising an external wheel assembly 2 mounted on the outer side of the wheelchair body 1, and a seat assembly 3 located at the middle of the wheelchair body 1; a counterweight assembly 4 nested and connected to the lower end of the seat assembly 3, and a movable guide 5 nested and mounted on the lower end face of the seat assembly 3; a return spring 6 fixedly connected to the outer side of the movable guide 5, and the return spring 6 and the lower end of the seat assembly 3 being mutually connected; a connecting connector 9 connected to the shaft end of the external wheel assembly 2, and the connecting connector 9 being rotatably connected to the wheelchair body 1; and an adaptive center of gravity adjustment mechanism provided between the external wheel assembly 2 and the seat assembly 3, which controls the overall tilt state of the wheelchair body 1.

[0037] The adaptive center of gravity adjustment mechanism is equipped with a contact switch assembly 7, which is mated to the surfaces of the movable guide 5 and the seat assembly 3. A reserved electric push rod 8 is installed inside the side end of the wheelchair body 1, and the reserved electric push rod 8 is electrically connected to the contact switch assembly 7. The reserved electric push rod 8 is powered by a reserved battery. A nested fitting 11 is nested inside the side end of the wheelchair body 1, and the lower end of the nested fitting 11 is mated to a guide connector 10. Magnets 12 are fixedly connected to the outer sides of both the guide connector 10 and the mating connector 9. An internal reserved liquid bladder 13 is bonded to the upper end of the nested fitting 11, and the internal reserved liquid bladder 13 is located inside the side end of the wheelchair body 1. When rod 8 receives an electrical signal from two sets of contact switch assemblies 7, it drives its output end to move downwards, and the reserved electric push rod 8 disengages from the limiting state between itself and the docking connector 9. The docking connector 9 rotates along the inner side of the wheelchair body 1. During the upward rotation of the docking connector 9, it simultaneously applies pressure to the contacting guide connector 10, and the guide connector 10 drives the upper nested fitting 11 to move in position simultaneously. The nested fitting 11 presses against the contacting built-in reserved liquid bladder 13. The entire wheelchair body 1, together with the counterweight assembly 4 that is always vertically downward at the lower end, effectively maintains its center of gravity. At the same time, when the user is subjected to external force and tilts or becomes skewed during climbing, the corresponding tilt angle is adjusted. The seat assembly 3 will be pressed against the counterweight assembly 4, which is in a vertical center of gravity downward, and simultaneously press the movable guide 5 at the corresponding position, thereby making the contact switch assemblies 7 contact each other. When the reserved electric push rod 8 receives the electrical signal generated by the two sets of contact switch assemblies 7, it will drive its output end to move downward, allowing the reserved electric push rod 8 to disengage from the limiting state between itself and the docking connector 9. At this time, the docking connector 9, which docks with the outer wheel assembly 2, will rotate upward along the outer side of the wheelchair body 1 according to the tilt state of the wheelchair body 1, thereby making the tilted wheelchair body 1 form a reverse support state. In conjunction with the counterweight assembly 4, the center of gravity of the wheelchair body 1 is changed, and the balance state of the wheelchair body 1 is controlled and adjusted (to be continued). After the heart returns to its original position, the reserved electric push rod 8, which is no longer in the electrical signal receiving state of the contact switch assembly 7, can drive its output end to reset upwards, thereby performing vertical support return processing of the external wheel assembly 2 along the hole-like structure with a larger bottom and smaller top on the end side of the docking connector 9, to avoid dangerous situations such as easy tipping over. During the reciprocating drive, the reserved electric push rod 8 will record data through the preset Bluetooth output end. If the number of drives is too many in a single period of time, a signal will be transmitted to the user's family member's mobile phone to remind the user's family member to go and accompany or observe in time, so as to avoid the user's activities on a bumpy road surface and subsequent adverse effects, effectively carrying out online and offline synchronous intelligent diagnosis and treatment.

[0038] Example 2: According to Figures 3-10 Based on Embodiment 1, to address the technical problem that, especially when encountering obstacles in blind spots, the wheelchair tilts at a large angle when the tires contact protruding objects, causing significant instability due to the shift in the user's center of gravity, a movable support structure is also disclosed. The specific structure is as follows:

[0039] The seat assembly 3 has a movable support structure on its inner side, which adaptively adjusts the occupant's center of gravity. The movable support structure includes a supply pipe 14, which is located inside the built-in pre-reserved liquid bladder 13 and runs along the inner side of the wheelchair body 1. The seat assembly 3 has an external pre-reserved liquid bladder 15 on its surface, which is connected to the supply pipe 14. The built-in pre-reserved liquid bladder 13 supplies liquid to the external pre-reserved liquid bladder 15 via the supply pipe 14, and the external pre-reserved liquid bladder 15 expands to provide support to the user's buttocks. The connecting member 9 moves upwards under pressure. During the process, the upper end will apply pressure to the contacting guide connector 10, thereby causing the guide connector 10 to drive the upper nested fitting 11 to move upward to the contacting built-in reserved liquid bladder 13. This allows the pressurized built-in reserved liquid bladder 13 to supply the external reserved liquid bladder 15 at the end through the supply pipe 14. The external reserved liquid bladder 15 will then expand and support the user's buttocks along the bottom of the seat assembly 3, prompting the user to move in the opposite direction of the side-tipping state. Even when encountering obstacles in the blind spot, or when the tires contact the protruding object and the wheelchair tilts at a large angle, the user's center of gravity will not shift and be subjected to lateral pressure.

[0040] Example 3: According to Figure 1 and Figures 10-12 Based on Embodiments 1 and 2, another transmission method of the adaptive center of gravity adjustment mechanism is also disclosed, the specific structure of which is as follows:

[0041] The adaptive center of gravity adjustment mechanism also includes a first liquid bladder component 16, which is located inside the seat assembly 3. The movable guide 5 has a protruding structure on its exterior, and the first liquid bladder component 16 corresponds to the outer side of the movable guide 5. A supply hose 17 is connected to the inner side of the first liquid bladder component 16, and the supply hose 17 passes through the inner side of the wheelchair body 1. A limiting docking component 19 is nested inside the inner side of the wheelchair body 1, and a spring component that docks with the inner side of the wheelchair body 1 is fixedly connected to the upper end of the limiting docking component 19. A second liquid bladder component 18 is connected to the outer side of the limiting docking component 19, and the second liquid bladder component 18 is connected to the supply hose 17. During the outward movement of the movable guide 5, pressure is applied to the contacting first liquid bladder component 16, and the first liquid bladder component 16 supplies liquid to the interior of the second liquid bladder component 18 through the supply hose 17. The second liquid bladder component 18 pushes the outer limiting docking member 19 downward along the inner side of the wheelchair body 1 until the limiting docking member 19 disengages from the limiting state between itself and the docking connector 9. During the outward movement of the movable guide member 5, it will apply pressure to the contacting first liquid bladder component 16 through the outer protrusion. The first liquid bladder component 16 will supply the second liquid bladder component 18 through the supply hose 17, thereby causing the second liquid bladder component 18 to push the outer limiting docking member 19 downward along the inner side of the wheelchair body 1 until the limiting docking member 19 disengages from the limiting state between itself and the docking connector 9. At this time, the docking connector 9 connected to the external wheel assembly 2 will simultaneously disengage from the limiting state, thereby effectively performing the reverse support work for the side-tilting state of the external wheel assembly 2. After disengaging from the force state, the docking connector 9 will then be reset through the corresponding spring assembly.
