Description

Technical Field

[0001] This invention relates to the field of assisted walking technology, and in particular to a foldable and convenient mobility scooter. Background Art

[0002] Mobility scooters are provided for use by obese individuals, people with disabilities, or those with limited mobility but not incapacitated, for purposes such as outings and camping. Sometimes, mobility scooters need to be folded up for easier transport.

[0003] However, existing mobility scooters have relatively complex folding structures, take a certain amount of time to fold, and are quite thick after folding, thus taking up a lot of space and making them inconvenient to store and transport. Summary of the Invention

[0004] Therefore, the main objective of this invention is to provide a foldable and convenient personal mobility vehicle that can be folded quickly and occupies little space.

[0005] To achieve the above objectives, the present invention provides a foldable and convenient mobility scooter, comprising:

[0006] Handle assembly;

[0007] A support component, wherein the handle component is disposed on the support component;

[0008] A support component is hinged to the load-bearing component, and the load-bearing component is rotatable relative to the support component to fold or unfold the mobility scooter;

[0009] The seat is detachably mounted on the support assembly;

[0010] A retaining element is disposed on the support assembly, the retaining element having an unfolding retaining slot and a folding retaining slot spaced apart; and

[0011] A locking component is rotatably disposed on the support component. The locking component can rotate relative to the support component to engage with the unfolding slot, thereby locking the vehicle in the unfolded state. The locking component can also rotate together with the support component relative to the support component to engage with the folding slot, thereby locking the vehicle in the folded state.

[0012] Preferably, the locking assembly includes a connecting plate and a first hinge shaft and a retaining shaft spaced apart on the connecting plate. The first hinge shaft is rotatably disposed on the bearing assembly. The retaining shaft and the connecting plate are rotatable relative to the bearing assembly around the first hinge shaft, so that the retaining shaft is engaged in the unfolding slot. The locking assembly is rotatable relative to the support assembly together with the bearing assembly, so that the retaining shaft is engaged in the folding slot.

[0013] Preferably, the locking assembly further includes a push-pull shaft disposed on the connecting plate, the push-pull shaft being spaced apart from the retaining shaft, and the push-pull shaft being located on the side of the retaining shaft away from the first hinge shaft.

[0014] Preferably, the locking assembly further includes a tension spring, and the mobility scooter further includes a second hinge shaft. The support assembly and the load-bearing assembly are hinged through the second hinge shaft. One end of the tension spring is connected to the holding shaft, and the other end of the tension spring is connected to the second hinge shaft. The tension spring has a preload force and can apply a tension force to the holding shaft that is held in the unfolding slot or the folding slot to prevent the holding shaft from disengaging from the unfolding slot or the folding slot.

[0015] Preferably, the load-bearing assembly includes a load-bearing tube, a first connecting rod, a second connecting rod, a first front wheel, and a second front wheel. The first connecting rod and the second connecting rod are disposed on both sides of the load-bearing tube. The first front wheel is rotatably disposed on the first connecting rod, and the second front wheel is rotatably disposed on the second connecting rod. The load-bearing assembly includes a first hinge plate and a second hinge plate. The first hinge plate and the second hinge plate are fixedly connected to the load-bearing tube and hinged to the support assembly.

[0016] Preferably, the load-bearing assembly further includes a first mounting bracket, a second mounting bracket, a first spring shock absorber, and a second spring shock absorber. The first mounting bracket and the second mounting bracket are fixedly disposed on both sides of the load-bearing tube. The end of the first connecting rod away from the first front wheel is rotatably connected to the first mounting bracket, and the end of the second connecting rod away from the second front wheel is rotatably connected to the second mounting bracket. The first spring shock absorber is disposed between the first connecting rod and the first mounting bracket, and the second spring shock absorber is disposed between the second connecting rod and the second mounting bracket. The first spring shock absorber is used to dampen the shock of the first front wheel, and the second spring shock absorber is used to dampen the shock of the second front wheel.

[0017] Preferably, the first spring shock absorber includes a shock-absorbing spring, a telescopic rod, a top seat, and a base. The top seat is rotatably mounted on the first mounting frame, and the base is rotatably mounted on the first connecting rod. One end of the telescopic rod is connected to the top seat, and the other end of the telescopic rod extends into the base. The telescopic rod is axially movable to extend and retract relative to the base. The shock-absorbing spring is sleeved on the telescopic rod. One end of the shock-absorbing spring is connected to the top seat, and the other end of the shock-absorbing spring is connected to the base. The axis of rotation between the first connecting rod and the first mounting frame is parallel to the horizontal direction.

[0018] Preferably, the mobility scooter further includes a tray, which is disposed below the first hinge plate, the second hinge plate and the support assembly, thereby restricting the downward rotation of the load-bearing assembly relative to the support assembly.

[0019] Preferably, the support assembly includes a support rod and a pedal and a first column spaced apart on the support rod, the seat is detachably mounted on the first column, the support rod is hinged to the load-bearing assembly, the load-bearing assembly is rotatable relative to the support assembly to fold or unfold the mobility scooter, and the retaining member is mounted on the support rod.

[0020] Preferably, there are two support rods, and the number of clamping members is the same as the number of support rods, with each clamping member corresponding to one of the support rods.

[0021] Preferably, the support assembly further includes a mounting component, a first rear wheel, and a second rear wheel, the first rear wheel and the second rear wheel being rotatably disposed at both ends of the mounting component.

[0022] Preferably, the mobility scooter further includes a drive unit connected to the first rear wheel, the drive unit being one in number and used only to drive the first rear wheel to rotate.

[0023] Preferably, the handle assembly includes a telescopic component and a handle. The telescopic component is disposed on the support component, and the handle is disposed on the telescopic component. The telescopic component is capable of telescopically extending and retracting along its own axis to adjust the height of the handle.

[0024] The technical solution of this invention has the following advantages: When the folding mobility scooter of this application needs to be folded, the seat is first removed, and then the handle assembly and the load-bearing assembly are driven to rotate relative to the support assembly, that is, the handle assembly is folded upwards, thereby realizing the folding of the handle assembly and the load-bearing assembly relative to the support assembly. On the one hand, the seat is removed in advance; on the other hand, the folding is not performed from the middle of the mobility scooter, but the handle assembly and the load-bearing assembly supporting the handle assembly are rotated relative to the support assembly. Therefore, after folding, the height of the mobility scooter is greatly reduced, making the folded mobility scooter flatter and occupying less space, which is more convenient for storage or transportation. In addition, by setting a retaining member and a locking member, when folding the mobility scooter, it is only necessary to drive the handle assembly and the load-bearing assembly to rotate relative to the support assembly, and the locking member is engaged in the folding slot of the retaining member to complete the folding process. Folding is convenient and fast, and the folding structure and folding process are very simple. Attached Figure Description

[0039] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, the descriptions involving "first," "second," etc., in the present invention are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the term "and / or" throughout the text includes three solutions. Taking A and / or B as an example, it includes technical solution A, technical solution B, and a technical solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0042] The following will mainly describe the specific structure of the foldable and convenient mobility scooter.

[0043] like Figure 1-5 As shown, a foldable mobility scooter includes a handlebar assembly 100, a load-bearing assembly 200, a support assembly 300, a seat 400, a retaining element 500, and a locking assembly 600. The handlebar assembly 100 is mounted on the load-bearing assembly 200, and the support assembly 300 is hinged to the load-bearing assembly 200. The load-bearing assembly 200 can rotate relative to the support assembly 300 to fold or unfold the mobility scooter. The seat 400 is detachably mounted on the support assembly 300. The retaining element 500 is mounted on the support assembly 300 and has an unfolding slot 510 and a folding slot 520 spaced apart. The locking assembly 600 is rotatably mounted on the load-bearing assembly 200 and can rotate relative to the load-bearing assembly 200 to retain the unfolding slot 510, thereby locking the mobility scooter in its unfolded state. The locking assembly 600 can also rotate together with the load-bearing assembly 200 relative to the support assembly 300 to retain the folding slot 520, thereby locking the mobility scooter in its folded state.

[0044] When the folding mobility scooter of this application needs to be folded up, the seat 400 is first removed, and then the handle assembly 100 and the load-bearing assembly 200 are driven to rotate relative to the support assembly 300, that is, the handle assembly 100 is folded upward, thereby realizing the folding of the handle assembly 100 and the load-bearing assembly 200 relative to the support assembly 300. On the one hand, the seat 400 is removed in advance. On the other hand, the folding is not performed from the middle of the support assembly 300, but the handle assembly 100 and the load-bearing assembly 200 supporting the handle assembly 100 are rotated relative to the support assembly 300. Thus, after the folding mobility scooter is folded up, the support assembly 300 is still flat. Only the handle assembly 100 and the load-bearing assembly 200 are folded up, making the mobility scooter flatter and occupying less space after folding. The height of the mobility scooter is relatively low, making it easier to store or transport the mobility scooter. Furthermore, by setting up a retaining component 500 and a locking component 600, when folding the mobility scooter, it is only necessary to drive the handle component 100 and the load-bearing component 200 to rotate together relative to the support component 300, and the locking component 600 is engaged in the folding slot 520 of the retaining component 500 to complete the folding process. The folding is convenient and fast, and the folding structure and folding process are very simple.

[0045] refer to Figure 3 and Figure 5-6 The locking component 600 includes a connecting plate 610 and a first hinge shaft 620 and a retaining shaft 630 spaced apart on the connecting plate 610. The first hinge shaft 620 is rotatably mounted on the bearing component 200. The retaining shaft 630 and the connecting plate 610 can rotate relative to the bearing component 200 around the first hinge shaft 620. When the mobility scooter is unfolded, the retaining shaft 630 is engaged in the unfolding slot 510. The locking component 600 can rotate relative to the support component 300 together with the bearing component 200. When the mobility scooter is folded, the retaining shaft 630 is engaged in the folding slot 520.

[0046] Specifically, when the mobility scooter needs to be folded, first, rotate the locking component 600 to release the engagement between the retaining shaft 630 and the unfolding slot 510. Then, rotate the locking component 600, the supporting component 200, and the handle component 100 together relative to the supporting component 300 until the retaining shaft 630 of the locking component 600 is engaged in the folding slot 520 of the retaining component 500, thereby completing the folding of the mobility scooter. The folded mobility scooter is as follows: Figure 12As shown; when the mobility scooter needs to be unfolded, first turn the rotating locking component 600 to release the clamping shaft 630 from the folding slot 520. Then, together with the supporting component 200 and the handle component 100, rotate the locking component 600 in the opposite direction to the previous rotation relative to the supporting component 300 until the mobility scooter is laid flat. Then, rotate the clamping shaft 630 and the connecting plate 610 around the first hinge shaft 620 relative to the supporting component 200 until the clamping shaft 630 is engaged in the unfolding slot 510, thus completing the unfolding of the mobility scooter. The unfolded mobility scooter is as follows: Figure 1 and Figure 7 As shown.

[0047] refer to Figure 3 and Figure 5-6 The locking assembly 600 also includes a push-pull shaft 640 disposed on the connecting plate 610. The push-pull shaft 640 is spaced apart from the retaining shaft 630, and is located on the side of the retaining shaft 630 away from the first hinge shaft 620. Specifically, when it is necessary to rotate the locking assembly 600, the push-pull shaft 640 can be held by hand to pull or push the locking assembly 600. The push-pull shaft 640 makes the operation of the locking assembly 600 more convenient.

[0048] refer to Figure 3 and Figure 5-6 The locking assembly 600 also includes a tension spring 650, and the mobility scooter also includes a second hinge shaft 700. The support assembly 300 and the load-bearing assembly 200 are hinged through the second hinge shaft 700. One end of the tension spring 650 is connected to the holding shaft 630, and the other end of the tension spring 650 is connected to the second hinge shaft 700. The tension spring 650 has a preload force and can apply a pulling force to the holding shaft 630 that is held in the unfolding slot 510 or the folding slot 520 to prevent the holding shaft 630 from disengaging from the unfolding slot 510 or the folding slot 520. Specifically, when the retaining shaft 630 is engaged in the unfolding slot 510 or the folding slot 520, the tension spring 650 can apply an elastic force to the retaining shaft 630, thereby making the retaining shaft 630 tightly abut against the bottom of the unfolding slot 510 or the folding slot 520, ensuring the reliability of the retaining shaft 630 relative to the unfolding slot 510 or the folding slot 520, and thus enabling the mobility scooter to be stably maintained in the unfolded or folded state.

[0049] refer to Figure 7-8 The load-bearing assembly 200 includes a load-bearing tube 210, a first connecting rod 220, a second connecting rod 230, a first front wheel 240, and a second front wheel 250. The first connecting rod 220 and the second connecting rod 230 are disposed on both sides of the load-bearing tube 210. The first front wheel 240 is rotatably disposed on the first connecting rod 220, and the second front wheel 250 is rotatably disposed on the second connecting rod 230.

[0050] refer to Figure 7-8The load-bearing assembly 200 also includes a first hinge plate 260 and a second hinge plate 270, which are fixedly connected to the load-bearing tube 210 and hinged to the support assembly 300. Specifically, the first hinge plate 260 and the second hinge plate 270 are hinged to the support assembly 300 via a second hinge shaft 700.

[0051] refer to Figure 7-8 The first hinge plate 260 and the second hinge plate 270 are provided with auxiliary slots 261. The auxiliary slots 261 are used to hold the locking shaft 630 of the locking component 600 in place when the locking component 600 is engaged in the unfolding slot 510, thereby preventing the locking shaft 630 from exiting the unfolding slot 510. When the mobility scooter is unfolded, the position of the auxiliary slots 261 corresponds to the position of the unfolding slot 510, and the locking shaft 630 is simultaneously engaged in both the auxiliary slots 261 and the unfolding slot 510. In this embodiment, when the mobility scooter is in the unfolded state, in addition to being hinged to the support component 300 via the second hinge shaft 700, the locking component 600's retaining shaft 630 is also simultaneously held in the unfolding slot 510 of the retaining member 500 and the auxiliary slots 261 of the two hinge plates. Thus, the support component 200 and the handle assembly 100 disposed on the support component 200 are supported and carried by the two hinge plates, the retaining member 500, and the support component 300 via the second hinge shaft 700 and the retaining shaft 630. That is, the second hinge shaft 700 and the retaining shaft 630 serve as two bearing shafts simultaneously, so that the support component 200 and the handle assembly 100 are reliably supported.

[0052] Specifically, the auxiliary slot 261 is designed so that when the mobility scooter is in the unfolded state, the retaining shaft 630 cannot disengage from the unfolding slot 510. When the mobility scooter needs to be folded, the handle assembly 100 is pushed forward first, which causes the supporting assembly 200 to move forward a small distance, so that the auxiliary slot 261 no longer abuts against the retaining shaft 630. Then, the push-pull shaft 640 is pulled, which can cause the retaining shaft 630 to exit the unfolding slot 510, thereby releasing the lock in the unfolded state. Then, the locking assembly 600 and the supporting assembly 200 are rotated relative to the supporting assembly 300 so that the retaining shaft 630 is engaged in the folding slot 520, thereby locking the mobility scooter in the folded state.

[0053] Furthermore, the opening size of the unfolding slot 510 is slightly larger than the diameter of the retaining shaft 630, thereby ensuring that the retaining shaft 630 can engage and disengage from the unfolding slot 510. (Reference) Figure 3 , 57, 8. When the mobility scooter is in the unfolded state, the front wall of the auxiliary slot 261 (referring to the slot wall of the auxiliary slot 261 near the handlebar assembly) is larger than the front wall of the unfolding slot 510 (referring to the slot wall of the unfolding slot 510 near the handlebar assembly). This causes the retaining shaft 630 to be engaged in the unfolding slot 510 and the auxiliary slot 261. At the same time, the front wall of the auxiliary slot 261 and the rear wall of the unfolding slot 510 abut against the front and rear sides of the retaining shaft 630, thereby preventing the retaining shaft 630 from disengaging from the unfolding slot 510 and the auxiliary slot 261.

[0054] refer to Figure 7-8 The load-bearing assembly 200 also includes a first mounting bracket 280, a second mounting bracket 290, a first spring shock absorber 2110, and a second spring shock absorber 2120. The first mounting bracket 280 and the second mounting bracket 290 are fixedly disposed on both sides of the load-bearing tube 210. The end of the first connecting rod 220 away from the first front wheel 240 is rotatably connected to the first mounting bracket 280, and the end of the second connecting rod 230 away from the second front wheel 250 is rotatably connected to the second mounting bracket 290. The first spring shock absorber 2110 is disposed between the first connecting rod 220 and the first mounting bracket 280, and the second spring shock absorber 2120 is disposed between the second connecting rod 230 and the second mounting bracket 290. The first spring shock absorber 2110 is used to dampen the first front wheel 240, and the second spring shock absorber 2120 is used to dampen the second front wheel 250.

[0055] refer to Figure 7-8 The load-bearing component 200 also includes a first mudguard 2130 and a second mudguard 2140. The first mudguard 2130 is mounted on the first mounting bracket 280 and is located directly above the first front wheel 240. The second mudguard 2140 is mounted on the second mounting bracket 290 and is located directly above the second front wheel 250. Specifically, both the first mudguard 2130 and the second mudguard 2140 are arc-shaped structures with a downward convex center. This arrangement of the first mudguard 2130 and the second mudguard 2140 can cover the area above, in front of, and behind the first front wheel 240 and the second front wheel 250, resulting in better mud protection. In addition, the first mudguard 2130 and the second mudguard 2140 can also be used by the user to extend their feet and step on them, serving a dual purpose.

[0056] refer to Figure 7-8The first spring shock absorber 2110 includes a shock-absorbing spring 2111, a telescopic rod 2112, a top seat 2113, and a base 2114. The top seat 2113 is rotatably mounted on the first mounting frame 280, and the base 2114 is rotatably mounted on the first connecting rod 220. One end of the telescopic rod 2112 is connected to the top seat 2113, and the other end of the telescopic rod 2112 extends into the base 2114. The telescopic rod 2112 can move along its own axis to extend and retract relative to the base 2114. The shock-absorbing spring 2111 is sleeved on the telescopic rod 2112. One end of the shock-absorbing spring 2111 is connected to the top seat 2113, and the other end of the shock-absorbing spring 2111 is connected to the base 2114. The axis of rotation between the first connecting rod 220 and the first mounting frame 280 is parallel to the horizontal direction. Specifically, when encountering a bumpy road surface, the first front wheel 240 and the first connecting rod 220 rotate together relative to the first mounting bracket 280, causing the first front wheel 240 and the first connecting rod 220 to swing upward, thereby driving the shock-absorbing spring 2111 to retract. At the same time, the telescopic rod 2112 extends into the base 2114, thereby playing a shock-absorbing and buffering role through the shock-absorbing spring 2111.

[0057] In this embodiment, the first spring damper 2110 includes only one first link 220, which is a single link structure. In contrast, the prior art has more than one double link or other more complex structures. The structure of the first spring damper 2110 in this application is simpler.

[0058] Furthermore, the structure of the second spring shock absorber 2120 is the same as that of the first spring shock absorber 2110. The matching relationship between the second spring shock absorber 2120 and the second front wheel 250 is the same as that between the first spring shock absorber 2110 and the first front wheel 240. Moreover, the rotation axis between the second connecting rod 230 and the second mounting bracket 290 is also parallel to the horizontal direction. The second spring shock absorber 2120 can also play a shock absorption role for the second front wheel 250. Specifically, when encountering a bumpy road surface, the first front wheel 240 and the first connecting rod 220 rotate together relative to the first mounting bracket 280, and the second front wheel 250 and the second connecting rod 230 rotate together relative to the second mounting bracket 290, so that the first front wheel 240 and the first connecting rod 220 swing upward, and the second front wheel 250 and the second connecting rod 230 swing upward, thereby driving the shock-absorbing spring 2111 to retract. At the same time, the telescopic rod 2112 extends into the base 2114, thereby playing a shock-absorbing and buffering role through the shock-absorbing spring 2111.

[0059] In this embodiment, the second spring damper 2120 is the same as the first spring damper 2110, and is also a single-link structure.

[0060] refer to Figure 3 and Figure 9The mobility scooter also includes a tray 800, which is positioned below the first hinge plate 260, the second hinge plate 270, and the support assembly 300, thereby restricting the downward rotation of the load-bearing assembly 200 relative to the support assembly 300. In this application, the load-bearing assembly 200 rotates upward relative to the support assembly 300, thereby enabling the mobility scooter to fold. This arrangement provides better load-bearing capacity and greater reliability.

[0061] refer to Figure 7 and Figure 9-10 The support assembly 300 includes a support rod 310 and a pedal 320 and a first column 330 spaced apart on the support rod 310. The seat 400 is detachably mounted on the first column 330. The support rod 310 is hinged to the load-bearing assembly 200, which is rotatable relative to the support assembly 300 to fold or unfold the mobility scooter. A retaining member 500 is mounted on the support rod 310. Specifically, the support rod 310 is hinged to the first hinge plate 260 and the second hinge plate 270 via a second hinge shaft 700.

[0062] refer to Figure 7 and Figure 9-10 There are two support rods 310, and the number of retaining members 500 is the same as that of the support rods 310, with each retaining member 500 corresponding to one support rod 310. Specifically, one support rod 310 is hinged to the first hinge plate 260 via the second hinge shaft 700, and the other support rod 310 is hinged to the second hinge plate 270 via the second hinge shaft 700, thereby making the hinge between the support assembly 300 and the load-bearing assembly 200 more stable and reliable. In addition, by setting two support rods 310 as the main beam structure of the mobility scooter, the load-bearing capacity of the mobility scooter is improved; the retaining shaft 630 of the locking assembly 600 is simultaneously engaged in the unfolding slot 510 and the folding slot 520 of the two retaining members 500, making the retaining and locking of the retaining shaft 630 more reliable and stable.

[0063] refer to Figure 9 The support assembly 300 also includes a mounting member 340, a first rear wheel 350 and a second rear wheel 360, with the first rear wheel 350 and the second rear wheel 360 rotatably mounted at both ends of the mounting member 340.
