Description

Technical Field

[0001] This application relates to the field of wheelchair technology, and in particular to a frame and wheelchair. Background Technology

[0002] As an important tool in the field of rehabilitation, wheelchairs not only provide basic mobility for people with physical disabilities and limited mobility, but are also a core tool for users to exercise, reintegrate into society, and participate in social activities. Therefore, the performance and design of wheelchairs are directly related to the user's rehabilitation process and degree of social integration.

[0003] Currently, mobile devices and mobility aids (including wheelchairs) on the market have significant structural design flaws. For example, their integrated, fixed design makes effective disassembly impossible. Wheelchairs are bulky and take up a lot of space, making long-distance transport or climbing stairs extremely inconvenient and causing great difficulties for users' daily travel and transportation. On the other hand, detachable heavy-duty mobility vehicles have unreasonable disassembly structures, with excessively heavy modules and complex disassembly operations, resulting in a poor user experience.

[0004] More importantly, existing detachable wheelchairs cannot achieve quick and precise positioning, assembly, and disassembly. After transport, users need to spend a lot of time and effort on complex alignment and fastening operations to restore the wheelchair to a safe and reliable state of use, which cannot meet the diverse lifestyle and travel needs of users. Utility Model Content

[0005] This application provides a frame and wheelchair, aiming to solve the problem that existing detachable mobility tools cannot achieve quick and accurate positioning, assembly, and disassembly.

One of the locking structure and the locking fitting structure has a switchable first form and a second form under the action of external force. In the first form, the locking structure and the locking fitting structure form a structural lock to fix the first support component and the second support component relatively. In the second form, the locking structure and the locking fitting structure disengage from the structural lock, and the first support component separates from the second support component.

[0007] Optionally, the first positioning auxiliary component has a sliding adapter, the second positioning auxiliary component has a groove, and the extension direction of the groove is the first direction.

[0009] Optionally, the first hook frame includes a hook frame body and a triggering component disposed on the hook frame body. The hook frame body is rotatably connected to the first mounting base and rotatably connected to the second mounting base through the triggering component. The triggering component, under the action of an external force, drives the hook frame body to rotate so that the locking structure switches from the first form to the second form, or from the second form to the first form.

[0010] Optionally, the first support frame includes a first movable frame, a second movable frame, and a first connecting component; the second support frame includes a second connecting component; the first movable frame has the bearing position formed thereon; and the first movable frame is movably connected to the second movable frame through the first connecting component and to the second support frame through the second connecting component. In the first configuration where the locking structure and the locking mating structure form a structural lock, the first movable frame is fixed relative to the second movable frame and the second support frame, respectively. In the second configuration where the locking structure and the locking fitting structure are disengaged, the first movable frame folds with the second movable frame via the first connecting member, and folds with the second support frame via the second connecting member.

[0011] Optionally, the first connecting component includes a third mounting base disposed on the first movable frame, a second hook frame movably hinged to the third mounting base, and an elastic member for providing elastic force to the second hook frame, wherein a first end of the elastic member is connected to the second hook frame, and a second end of the elastic member is connected to the third mounting base; The third mounting base is also provided with a locking pin, and the second hook frame is provided with a first mating part that is adapted to the locking pin; Under the action of external force, the second hook frame rotates relative to the third mounting base through the elastic element so that the locking pin engages or disengages from the first mating part.

[0012] Optionally, the first bracket component further includes a first movable rod, which is spaced apart from the first movable frame and movably connected to the second movable frame and the second support frame, respectively.

[0013] Optionally, the second support frame includes at least a first crossbar and a first longitudinal bar and a second longitudinal bar arranged at intervals, and the second bracket component includes at least a first crossbeam and a first longitudinal beam and a second longitudinal beam arranged at intervals. The first crossbar is connected to the first longitudinal bar and the second longitudinal bar respectively, and the first crossbeam is connected to the first longitudinal beam and the second longitudinal beam respectively; The first crossbar is provided with a locking structure, at least one of the first longitudinal bar and the second longitudinal bar is provided with the first positioning auxiliary component, the first crossbeam is provided with a locking fitting structure for structural locking with the locking structure, and at least one of the first longitudinal beam and the second longitudinal beam is provided with a second positioning auxiliary component for sliding connection with the first positioning auxiliary component.

[0014] Optionally, the second bracket component further includes a handle assembly, wherein at least one of the first bracket component and the second bracket component is provided with a wheel assembly mounting portion, and the handle assembly is located on the side of the second bracket component away from the wheel assembly mounting portion.

[0015] Secondly, this application also provides a wheelchair, the wheelchair including the aforementioned frame and wheel assembly, wherein at least one of the first support component and the second support component is provided with a wheel assembly mounting portion, and the wheel assembly is mounted on the wheel assembly mounting portion.

[0016] The frame provided in this application adopts a modular design, which is designed as a detachable first support component and a second support component. The two support components are accurately and quickly guided and positioned by the cooperation of the first positioning auxiliary component and the second auxiliary positioning component. The two components can be quickly disassembled or flexibly assembled into a complete frame structure by the combination of the locking structure and the locking fit mating structure.

[0017] This detachable structure allows users to easily assemble the two parts into a stable frame during use to meet load-bearing requirements. During transportation or handling, the frame can be disassembled into two independent components, effectively reducing overall space occupation and facilitating storage and handling, thereby lowering transportation costs and improving space utilization efficiency. Unlike traditional disassembly methods, the frame provided in this application eliminates the need to lay the entire device on its side or flip it over, or to squat. Users can complete the disassembly and assembly of the frame while standing, reducing physical burden and avoiding the risk of bumps and collisions, thus enhancing safety. Furthermore, the frame provided in this application achieves precise positioning and guidance through a first positioning auxiliary component and a second auxiliary positioning component. In other words, users do not need tools or repeated adjustments; the guidance and limiting of the first and second auxiliary positioning components ensure the accuracy of frame assembly, enabling rapid alignment and further improving the user experience.

[0018] Furthermore, this application also provides a wheelchair with the aforementioned frame, which also has the advantages of the aforementioned frame, namely, the wheelchair can be quickly disassembled into two parts, greatly reducing its size and improving portability. At the same time, during the loading and unloading of the wheelchair, there is no need to laboriously flip the bulky chair, and frequent squatting and bending are avoided. The operation process is safe and labor-saving, significantly reducing the operating threshold and physical burden. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] As an important tool in the field of rehabilitation, wheelchairs not only provide basic mobility for people with physical disabilities and limited mobility, but are also a core tool for users to exercise, reintegrate into society, and participate in social activities. Therefore, the performance and design of wheelchairs are directly related to the user's rehabilitation process and degree of social integration.

[0025] Currently, mobile devices and mobility aids (including wheelchairs) on the market have significant structural design flaws. For example, most traditional wheelchairs use a one-piece frame structure, which, while ensuring overall stability, presents significant drawbacks in transportation and storage. Due to their non-detachable, bulky design, wheelchairs take up a lot of space, making them difficult to fit into the trunk of a typical family car. When they do fit, multiple people are needed to lift them, which is extremely inconvenient for long-distance transport or climbing stairs. This severely limits the handling and transportation of wheelchairs, causing significant difficulties for users' daily travel and transportation.

[0026] Meanwhile, integrated wheelchairs also take up considerable storage space in homes or medical facilities. Although some wheelchairs are detachable, their detachment structures are often poorly designed, requiring either a complete flip or complex operation that necessitates frequent squatting by the user. These issues do not fundamentally address the pain points of cumbersome assembly and disassembly, or inconvenient operation, resulting in a poor user experience.

[0027] More importantly, existing detachable wheelchairs cannot achieve quick and precise positioning and assembly. After transport, users need to spend a lot of time and effort on complex alignment and fastening operations to restore the wheelchair to a safe and reliable state of use, which cannot meet the diverse lifestyle and travel needs of users.

[0028] To address the aforementioned technical problems, this application provides a vehicle frame that enables rapid and precise positioning, assembly, and disassembly, aiming to solve the problem of unreasonable disassembly structures in existing personal transportation tools.

[0029] The frame of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Please see Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural diagram of the vehicle frame provided by this utility model. Figure 2 This is an exploded view of the three-dimensional structure of the vehicle frame.

[0031] like Figure 1 and Figure 2 As shown, the vehicle frame 10 provided in this application includes a first support component 1 and a second support component 2. The first support component 1 includes a first support frame 11 and a second support frame 12. The first support frame 11 forms a bearing position. The first support component 1 also includes a locking structure 13 and a first positioning auxiliary component 14, which are disposed on the second support frame 12.

[0032] The second support component 2 includes a locking fitting structure 21 and a second positioning auxiliary component 22. The second positioning auxiliary component 22 is slidably connected to the first positioning auxiliary part in the first direction and can form a limiting fit in the second direction. The first direction and the second direction are set at an angle.

[0033] Among them, one of the locking structure 13 and the locking fitting structure 21 has a switchable first form and a second form under the action of external force. In the first form, the locking structure 13 and the locking fitting structure 21 form a structural lock to fix the first support component 1 and the second support component 2 relatively. In the second form, the locking structure 13 and the locking fitting structure 21 disengage from the structural lock, and the first support component 1 and the second support component 2 separate.

[0034] Specifically, in some examples, the first support frame 11 and the second support frame 12 can support the target object carried on the bearing position in at least two different directions to improve the stability, safety, and comfort of the bearing position. At least one of the first support component 1 and the second support component 2 is provided with a wheel assembly mounting part 3.

[0035] It should be understood that the locking structure 13 can be disposed on the first support component 1 or the second support component 2, and correspondingly, the locking mating structure 21 can be disposed on the second support component 2 or the first support component 1. Similarly, the first positioning auxiliary component 14 can be disposed on the first support component 1 or the second support component 2, and correspondingly, the second positioning auxiliary component 22 can be disposed on the second support component 2 or the first support component 1. This application does not impose any limitations.

[0036] For example, the first support component 1 is provided with a locking structure 13 and a first positioning auxiliary component 14, and the second support component 2 is provided with a locking fitting structure 21 and a second positioning auxiliary component 22. Alternatively, the first support component 1 is provided with a locking fitting structure 21 and a first positioning auxiliary component 14, and the second support component 2 is provided with a locking structure 13 and a second positioning auxiliary component 22. Or, the first support component 1 is provided with a locking structure 13 and a second positioning auxiliary component 22, and the second support component 2 is provided with a locking fitting structure 21 and a first positioning auxiliary component 14. Still, the first support component 1 is provided with a locking fitting structure 21 and a second positioning auxiliary component 22, and the second support component 2 is provided with a locking structure 13 and a first positioning auxiliary component 14.

[0037] In this embodiment, the frame 10 adopts a modular design, comprising a detachable first support component 1 and a second support component 2. Precise and rapid guiding and positioning of the two support components is achieved through the cooperation of a first positioning auxiliary component 14 and a second auxiliary positioning component. Furthermore, the combination of a locking structure 13 and a locking fitting structure 21 allows for quick disassembly or flexible assembly into a complete frame 10 structure. Specifically, the sliding connection in the first direction and the limiting cooperation in the second direction of the first positioning auxiliary component 14 and the second auxiliary positioning component enable rapid and precise positioning of the first support component 1 and the second support component 2, which are then combined through the locking structure 13 and the locking fitting structure 21.

[0038] With this detachable structure, users can easily assemble the two parts into a stable frame 10 during use to meet load-bearing requirements. During transportation or handling, the frame 10 can be disassembled into two independent components, effectively reducing overall space occupation and facilitating storage and handling, thereby lowering transportation costs and improving space utilization efficiency. Furthermore, unlike traditional disassembly methods, the frame 10 provided in this application does not require the entire device to be placed on its side or flipped, nor does it require squatting. Users can complete the disassembly and assembly of the frame 10 while standing, reducing physical burden and avoiding the risk of bumps and collisions, thus enhancing safety. In addition, the frame 10 provided in this application achieves precise positioning and guidance through the first positioning auxiliary component 14 and the second auxiliary positioning component. In other words, users do not need tools or repeated adjustments; the guidance and limiting of the first positioning auxiliary component 14 and the second auxiliary positioning component ensure the assembly accuracy of the frame 10, thereby achieving rapid alignment and assembly, further improving the user experience.

[0039] Specifically, such as Figure 2 As shown, in use, the first positioning auxiliary component 14 and the second positioning auxiliary component 22 form a sliding connection in the first direction. The user sits on the support position in the first direction. When disassembling, the user unlocks the locking structure 13 and lifts the second support component 2 in the opposite direction to the first direction, so that the first support component 1 and the second support component 2 can be separated.

[0040] Specifically, in some embodiments, the first support component 1 further includes a second crossbar 124, which is connected to the first support frame 11 to form a bearing position.

[0041] In this embodiment, the second crossbar 124 serves as a component of the bearing position, enhancing the structural strength of the bearing position, providing stable support for the bearing position, making the force on the bearing position more balanced, and indirectly reducing the stress on the locking structure 13.

[0042] In some specific examples, the second support component 2 further includes a handle assembly 26, at least one of the first support component 1 and the second support component 2 is provided with a wheel assembly 3, and the handle assembly 26 is provided on the side of the second support component 2 away from the wheel assembly 3.

[0043] It is understood that in this embodiment, caregivers or companions can use the handle assembly 26 to push the frame 10 or wheelchair to perform operations such as moving forward, turning, or climbing. Specifically, in some examples, the height, spacing, and grip of the handle assembly 26 are designed to fit the arm posture of a person standing and pushing, reducing fatigue in the wrists and shoulders of caregivers during long-term pushing and improving the comfort of assisted operation.

[0044] For example, the height of the handle assembly 26 can be achieved by adding a telescopic rod connected to the handle assembly 26, thereby adjusting the height of the handle assembly 26 to accommodate caregivers or companions of different heights.

[0045] More specifically, a braking component can also be installed on the handle assembly 26, which can be used by the user or assistant to trigger the brake, preventing the wheelchair from sliding on slopes or downhill sections and improving mobility safety.

[0046] Please see Figure 3 and Figure 4 ,like Figure 3 and Figure 4 As shown, in some embodiments, the second support frame 12 includes at least a first crossbar 121 and a first longitudinal bar 122 and a second longitudinal bar 123 spaced apart, and the second support component 2 includes at least a first crossbeam 23 and a first longitudinal beam 24 and a second longitudinal beam 25 spaced apart. The first crossbar 121 is connected to the first longitudinal bar 122 and the second longitudinal bar 123 respectively, and the first crossbeam 23 is connected to the first longitudinal beam 24 and the second longitudinal beam 25 respectively.

[0047] The first crossbar 121 is provided with a locking structure 13, at least one of the first longitudinal bar 122 and the second longitudinal bar 123 is provided with a first positioning auxiliary component 14, the first crossbeam 23 is provided with a locking fitting structure 21 for structural locking with the locking structure 13, and at least one of the first longitudinal beam 24 and the second longitudinal beam 25 is provided with a second positioning auxiliary component 22 for sliding connection with the first positioning auxiliary component 14.

[0048] In this embodiment, a first positioning auxiliary component 14 is provided in at least one of the first longitudinal bar 122 and the second longitudinal bar 123, and a second positioning auxiliary component 22 for sliding connection with the first positioning auxiliary component 14 is provided in at least one of the first longitudinal beam 24 and the second longitudinal beam 25. This achieves guiding and positioning of the components between the first support component 1 and the second support component 2 to limit the relative displacement between the components. The locking structure 13 of the first crossbar 121 and the locking fitting structure 21 of the first crossbeam 23 form a lock, achieving a rigid locking and fixing effect on the first support component 1 and the second support component 2, preventing loosening of the first support component 1 and the second support component 2 due to force or vibration during use. Therefore, the cooperation of the first positioning auxiliary component 14 and the second positioning auxiliary component 22, and the cooperation of the locking structure 13 and the locking fitting structure 21, achieve precise positioning and locking of the first support component 1 and the second support component 2.

[0049] It can also be understood that when setting the locking structure 13 and the locking fitting structure 21, the locking structure 13 can be set on the first crossbar 121, and the locking fitting structure 21 forming a structural lock with the locking structure 13 can be set on the first crossbeam 23; or the locking fitting structure 21 can be set on the first crossbar 121, and the locking structure 13 forming a structural lock with the locking fitting structure 21 can be set on the first crossbeam 23. Similarly, when setting the first positioning auxiliary component 14 and the second positioning auxiliary component 22, the first positioning auxiliary component 14 can be set on at least one of the first longitudinal bar 122 and the second longitudinal bar 123, and the second positioning auxiliary component 22 for forming a sliding connection with the first positioning auxiliary component 14 can be set on at least one of the first longitudinal beam 24 and the second longitudinal beam 25. Alternatively, the second positioning auxiliary component 22 can be set on at least one of the first longitudinal bar 122 and the second longitudinal bar 123, and the first positioning auxiliary component 14 forming a sliding connection with the second positioning auxiliary component 22 can be set on at least one of the first longitudinal beam 24 and the second longitudinal beam 25. This application does not impose any limitations.

[0050] Specifically, in some embodiments, the first positioning auxiliary component 14 is formed with a sliding adapter 141, and the second positioning auxiliary component 22 is formed with a groove 221, and the extension direction of the groove 221 is a first direction.

[0051] For example, the user can roughly align the first positioning auxiliary component 14 of the first bracket component 1 with the second positioning auxiliary component 22 of the second bracket component 2 to guide the sliding adapter 141 of the first positioning auxiliary component 14 into the groove 221 of the second positioning auxiliary component 22 to achieve a sliding connection. At this time, the first positioning auxiliary component 14 slides along the extension direction of the groove 221, ensuring that the two components can smoothly approach each other along a predetermined path. Simultaneously, during the sliding process, the very small gap between the sliding adapter 141 and the groove 221 effectively limits the displacement and wobbling of the first positioning auxiliary component 14 and the second auxiliary positioning component 22. When the sliding adapter 141 slides to the bottom of the groove 221, the user operates the locking structure 13 to complete the assembly.

[0052] It is understandable that the locking structure 13 may be, for example, a quick-release buckle, a rotary locking knob, or a combination of magnetic and mechanical locks.

[0053] Please see Figures 4 to 6 In some embodiments, the second support frame 12 includes a second connecting member 125, and the second support frame 12 is movably connected to the second bracket member 2 through the second connecting member 125.

[0054] In the first configuration where the locking structure 13 and the locking fitting structure 21 are structurally locked, the second support frame 12 is relatively fixed to the first support frame 11. In the second configuration where the locking structure 13 and the locking fitting structure 21 are disengaged, the second support frame 12 is folded together with the first support frame 11 via the second connecting member 125.

[0055] In this embodiment, in the first configuration where the locking structure 13 and the locking fitting structure 21 are structurally locked, the second support frame 12 is fixed relative to the first support frame 11 to achieve stable load-bearing, and can support the target object supported at the bearing position in at least two different directions. In the second configuration where the locking structure 13 and the locking fitting structure 21 are disengaged, the second support frame 12 is folded together with the first support frame 11 via the second connecting member 125, which reduces the storage volume.

[0056] Furthermore, in some specific examples, the first support frame 11 includes a first movable frame 111, a second movable frame 112, and a first connecting member 113. The first movable frame 111 has a bearing position, and the first movable frame 111 is movably connected to the second movable frame 112 through the first connecting member 113, and is movably connected to the second support frame 12 through the second connecting member 125.

[0057] In the first configuration where the locking structure 13 and the locking fitting structure 21 are structurally locked, the first movable frame 111 is fixed relative to the second movable frame 112 and the second support frame 12, respectively. In the second configuration where the locking structure 13 and the locking fitting structure 21 are disengaged, the first movable frame 111 is folded together with the second movable frame 112 via the first connecting member 113, and also folded together with the second support frame 12 via the second connecting member 125.

[0058] In this embodiment, in the first state where the locking structure 13 and the locking fitting structure 21 are structurally locked, the first movable frame 111 is fixed relative to the second movable frame 112 and the second support frame 12, respectively, thus providing stable support for the bearing position. In the second state where the locking structure 13 and the locking fitting structure 21 are disengaged, as... Figure 6 As shown, the first movable frame 111 can be folded with the second movable frame 112 via the first connecting part 113, and folded with the second support frame 12 via the second connecting part 125, so that the huge frame 10 structure can be formed into three folds, greatly reducing the volume and making it easy to store or transport.

[0059] It is understandable that users can choose whether to disassemble or fold the frame 10 according to their actual needs. For example, in practical application scenarios, users can simply disassemble the frame 10 into the first support component 1 and the second support component 2. Alternatively, with the first support component 1 and the second support component 2 separated, users can choose to fold the first movable frame 111, the second movable frame 112, and the second support frame 12 in the first support component 1 before storage. Or, when the first support component 1 and the second support component 2 are assembled into the frame 10, the first movable frame 111, the second movable frame 112, and the second support frame 12 in the first support component 1 can be folded to meet the need for quick adjustment of the state in short-term storage situations. For example, when waiting for a train, the frame 10 can be transformed from a user-occupied state to a compact state that is easy to temporarily store, so that it can be quickly restored to use after arriving at the destination. This setting can flexibly meet the storage needs of different scenarios, reducing space occupation during waiting and improving travel convenience through efficient structural transformation.

[0060] In some embodiments, the first support component 1 further includes a first movable rod 15, which is movably connected to the second movable frame 112 and the second support frame 12, and the first movable rod 15 and the first movable frame 111 are spaced apart.

[0061] In this embodiment, the first movable rod 15 is movably connected to both the second movable frame 112 and the second support frame 12. When the first support component 1 and the second support component 2 are locked in place, the first movable rod 15 can work in concert with the first connecting component 113 and the second connecting component 125 to distribute the pressure on the bearing position of the first movable frame 111, thus avoiding overload and improving the overall deformation resistance and stability of the frame 10. Simultaneously, since the first movable rod 15 is movably connected to both the second movable frame 112 and the second support frame 12, this arrangement preserves the necessary movement space for folding while limiting unintended displacement between the second movable frame 112 and the second support frame 12 through the rigidity of the rod during use, reducing structural sway and making the load-bearing capacity more stable.

[0062] like Figure 4 and Figure 5 As shown, in some embodiments, the locking structure 13 includes a first mounting base 131, a first hook bracket 132 and a second mounting base 133. The first mounting base 131 and the second mounting base 133 are disposed on the second support frame 12, and the first hook bracket 132 is rotatably connected to the first mounting base 131 and the second mounting base 133 respectively.

[0063] Under the action of external force, the first hook 132 rotates relative to the first mounting base 131 and the second mounting base 133 so that the locking structure 13 has a switchable first form and a second form.

[0064] For example, such as Figure 5 As shown, in some specific examples, the first mounting base 131 is also provided with a limiting part 131a for fixing the second bracket component 2. By setting the limiting part 131a, the limiting part 131a limits the second bracket component 2 during the sliding connection process of the first positioning auxiliary component 14 and the second positioning auxiliary component 22, ensuring that the first positioning auxiliary component 14 and the second positioning auxiliary component 22 reach the assembly position in the first direction. Then, the second bracket component 2 is fixed by the first hook 132, thus achieving fast and accurate positioning and assembly. Specifically, the limiting part 131a can be a groove structure, and the first hook 132 has a fixing part 132a. During disassembly, an external force is applied to make the first hook 132 rotate relative to the first mounting base 131 and the second mounting base 133, thereby causing the limiting part 131a of the first mounting base 131 and the fixing part 132a of the first hook 132 to disengage from the second bracket component 2, thus separating the first bracket component 1 and the second bracket component 2.

[0065] In this embodiment, the locking structure 13 switches between its first and second forms through the cooperation of the first hook 132 with the first mounting base 131 and the second mounting base 133. In the first form, the locking structure 13 and the locking fitting structure 21 form a rigid lock, thereby fixing the relative positions of the first support frame 11 and the second bracket component 2. This prevents the frame 10 from loosening due to vibration or stress during user use, ensuring the structural stability and safety of the frame 10. In the second form, the second bracket component 2 separates from the first support frame 11 on the side away from the wheel assembly mounting part 3. That is, the separation direction of the second bracket component 2 from the first bracket component 1 is opposite to the user's sitting direction. This arrangement eliminates the need for the user to manually turn or flip the frame 10; the user can easily separate the frame 10 into the first bracket component 1 and the second bracket component 2 while standing. This avoids the user having to laboriously flip the heavy chair and eliminates the need for frequent squatting and bending, making the operation safer and less strenuous, significantly reducing the operational threshold and physical burden.

[0066] Specifically, in some embodiments, the first hook frame 132 includes a hook frame body 1321 and a triggering component 1322 disposed on the hook frame body 1321. The hook frame body 1321 is rotatably connected to the first mounting base 131 and is rotatably connected to the second mounting base 133 via the triggering component 1322. Under the action of an external force, the triggering component 1322 drives the hook frame body 1321 to rotate, causing the locking structure 13 to switch from a first form to a second form, or from a second form to a first form.

[0067] In this embodiment, the design of the triggering component 1322 provides the user with a force application point to drive the hook frame body 1321 to rotate in order to achieve locking or disengagement. In some specific examples, the hook frame body 1321 has a fixing part 132a for engaging the second support component 2 to fix the second support component 2. The fixing part 132a can be, for example, a protrusion, which further enhances the stability of the locking state.

[0068] Please see Figure 7 ,like Figure 7 As shown, in some embodiments, the first connecting component 113 includes a third mounting base 114 disposed on the first movable frame 111, a second hook 115 movably hinged to the third mounting base 114, and an elastic member 116 for providing elastic force to the second hook 115. The first end of the elastic member 116 is connected to the second hook 115, and the second end of the elastic member 116 is connected to the third mounting base 114.

[0069] The third mounting base 114 is also provided with a locking pin 117, and the second hook frame 115 is provided with a first mating part 115a that is adapted to the locking pin 117. Under the action of external force, the second hook frame 115 rotates relative to the third mounting base 114 through the elastic member 116 so that the locking pin 117 and the first mating part 115a can be engaged or disengaged.

[0070] It is understood that when the locking pin 117 is engaged with the first mating part 115a, the first movable frame 111 and the second movable frame 112 are relatively fixed. When the locking pin 117 is disengaged from the first mating part 115a, the first movable frame 111 is folded together with the second movable frame 112 via the first connecting member 113, and is also folded together with the second support frame 12 via the second connecting member 125.

[0071] For example, when a user applies external force to rotate the second hook 115 counterclockwise, the first engaging portion 115a on the second hook 115 disengages from the locking pin 117, allowing the frame 10 to be folded. When the user applies external force to rotate the second hook 115 clockwise to engage the first engaging portion 115a with the locking pin 117, the frame 10 is ready for use and can carry loads. In some specific examples, the locking pin 117 may also be fixedly mounted on the second movable frame 112; this is not a limitation.

[0072] In this embodiment, the combination of the third mounting base 114, the second hook 115, and the elastic element 116 utilizes the elastic force of the elastic element 116 to drive the second hook 115 to engage or disengage with the locking pin 117 on the third mounting base 114. Only simple external force is required to fix or trigger the folding of the first movable frame 111 and the second movable frame 112. The structure is simple and requires few components, reducing both production costs and the probability of equipment failure and maintenance. Simultaneously, in the unlocked state where the second hook 115 is disengaged from the locking pin 117, not only are the first movable frame 111 and the second movable frame 112 folded, but the folding of the first movable frame 111 and the second support frame 12 is also simultaneously facilitated, enabling multiple components to work together to form a linked folding mechanism, thus improving the efficiency of structural transformation.

[0073] Secondly, this application also provides a wheelchair, which includes the aforementioned frame 10 and wheel assembly 27, and at least one of the first support component 1 and the second support component 2 is provided with a wheel assembly mounting part 3, on which the wheel assembly 27 is mounted. The specific structure of the frame 10 can be found in the aforementioned embodiments and will not be repeated here.

[0074] As can be seen from the above, the wheelchair proposed in this application, since it includes the frame 10 mentioned above, also has the advantages of the frame 10 of this application. The wheelchair has the advantages of being detachable and foldable. Users can disassemble the wheelchair into the first support component 1 and the second support component 2 as needed, or fold the first movable frame 111 and the second movable frame 112 through the first connecting component 113 in the assembled state. This allows the wheelchair to significantly reduce its size when stored for a long time, and to quickly switch to a compact state in short-term scenarios such as waiting for a bus, reducing space occupation and improving travel convenience.

[0075] It can also be understood that, in some specific embodiments, the wheel assembly mounting part 3 includes a first wheel assembly mounting part and a second wheel assembly mounting part. The first wheel assembly mounting part is disposed on the first bracket component 1, and the second wheel assembly mounting part is disposed on the second bracket component 2. The wheel assembly 27 includes a first wheel assembly and a second wheel assembly. The first wheel assembly is mounted on the first wheel assembly mounting part, and the second wheel assembly is mounted on the second wheel assembly mounting part. The first wheel assembly mounting part and the second wheel assembly mounting part may be the same or different, and this application does not impose any limitations on this.
