[0002] Currently, the seats of most mobility scooters on the market are fixed in the fore-aft direction and only have a rotation adjustment function. However, this rotation adjustment mechanism is an integral structure with the seat, which not only makes the seat heavy but also cannot be separated and can only be used in conjunction with it. The rotation adjustment mechanism cannot be removed from the mobility scooter, which cannot meet the comfort needs of all users. Utility Model Content

[0003] This disclosure provides an adjustable seat structure and a mobility scooter to at least solve the above-mentioned technical problems existing in the prior art.

[0004] According to a first aspect of this disclosure, an adjustable seat structure is provided, comprising:

[0005] A base for connecting to the vehicle frame, wherein a slide rail is provided on the base;

[0006] A moving mechanism includes a mounting base and a moving adjustment assembly. The mounting base is slidably connected to the base via a slide rail. The moving adjustment assembly is disposed on the base and is capable of locking and unlocking the mounting base.

[0007] A rotating mechanism is rotatably connected to the mounting base. The rotating mechanism includes a rotating adjustment component. The mounting base has a positioning hole. The rotating adjustment component can drive the rotating mechanism to rotate relative to the mounting base and cooperates with the positioning hole for limiting its position.

[0008] The rotating mechanism has a locked state and an unlocked state. When the rotating mechanism is in the locked state, the rotating adjustment component and the positioning hole are engaged. When an external force is applied to the rotating adjustment component to separate the rotating adjustment component and the positioning hole, the rotating mechanism switches to the unlocked state.

[0009] In one embodiment, the rotating mechanism includes a turntable rotatably connected to the mounting base and an elastic element fixedly connected to the lower surface of the turntable, the elastic element being connected to the mounting base via the rotation adjustment assembly.

[0010] In one embodiment, the elastic element includes a fixed end and a free end. The fixed end is fixedly connected to the lower surface of the turntable and can rotate with the turntable, while the free end is in contact with the mounting base.

[0011] In one embodiment, the rotation adjustment assembly includes a positioning part disposed on the lower surface of the free end and a handheld part fixedly connected to the free end; wherein, when the rotation mechanism is in a locked state, the positioning part engages with the positioning hole; when an external force is applied to the handheld part, the elastic element undergoes elastic deformation, thereby separating the positioning part from the positioning hole.

[0012] In one embodiment, a first annular groove is provided on the mounting base and on the side that cooperates with the turntable, and a second annular groove is provided on the turntable and on the side that cooperates with the mounting base. The second annular groove corresponds to the first annular groove, and the first annular groove (211) and the second annular groove are connected by a rolling assembly.

[0013] In one embodiment, the mounting base is provided with a plurality of slots along the moving direction of the mounting base, and the plurality of slots are provided on the side of the mounting base, and the slots can engage and limit the movement adjustment component.

[0014] In one embodiment, the movable adjustment assembly includes a locking pin rotatable about a rotation center, and a positioning block is fixedly connected to the locking pin, the positioning block engaging with the slot; wherein the rotation center and the moving direction are parallel.

[0015] In one embodiment, the movable adjustment assembly further includes an adjustment fixing part disposed on the base, the locking pin passing through the adjustment fixing part, and the positioning block located inside the adjustment fixing part.

[0016] In one embodiment, the base is provided with a fixed baffle, which is fixed to the side of the slide rail and covers part of the slide rail. A folding part is provided at the connection between the mounting base and the slide rail, and the folding part is embedded between the fixed baffle and the slide rail.

[0017] According to a second aspect of this disclosure, a mobility scooter is provided, the mobility scooter being provided with an adjustable seat structure as described in any of the above-described embodiments.

[0018] In this disclosure, the adjustable seat structure includes a moving mechanism and a rotating mechanism. The mounting base in the moving mechanism can drive the rotating mechanism to slide along a slide rail, adjusting the seat to move closer to or further from the handlebars. Since the rotating mechanism is rotatably connected to the mounting base, it can rotate around a pivot, thereby causing the seat to rotate synchronously and adjusting the seat's rotation angle. A rotating adjustment component is provided to lock and unlock the rotating mechanism. Therefore, the adjustable seat structure of this disclosure combines fore-and-aft adjustment and rotation adjustment functions, offering high flexibility. It is also compact, occupies little space, and the base can be detached from the frame.

Detailed Implementation

[0028] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0029] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0030] Reference Figures 1-5 As shown, this disclosure presents an exemplary embodiment of an adjustable seat structure, including a base 1, a moving mechanism 2, and a rotating mechanism 3. The base 1 has a mounting hole 12 for detachable connection to a vehicle frame, and a slide rail 11. The moving mechanism 2 includes a mounting seat 21 and a moving adjustment component 22. The mounting seat 21 is slidably connected to the base 1 via the slide rail 11. The moving adjustment component 22 is disposed on the base 1 and can lock and unlock the mounting seat 21. The rotating mechanism 3 is rotatably connected to the mounting seat 21 and includes a rotating adjustment component 33. The mounting seat 21 has a positioning hole 331. The rotating adjustment component 33 can drive the rotating mechanism 3 to rotate relative to the mounting seat 21 and engage with the positioning hole 331 for limiting. The rotating mechanism 3 has a locked state and an unlocked state. When the rotating mechanism 3 is in the locked state, the rotating adjustment component 33 and the positioning hole 331 are engaged. When an external force is applied to the rotating adjustment component 33 to separate it from the positioning hole 331, the rotating mechanism 3 switches to the unlocked state.

[0031] In this embodiment, it should first be noted that the forward, backward, left, right, up, and down directions in this disclosure are based on the direction of the adjustable seat structure during normal use. For example, when the rotating mechanism 3 is positioned directly in front of the mobility scooter and does not rotate, the mounting base 21 slides along the slide rail 11, which means that the mounting base 21 drives the seat to adjust forward and backward. After the seat is adjusted in the forward and backward direction, the rotating mechanism 3 can also be rotated to the left or right. The structure of the rotating mechanism 3 and the mounting base 21 can be designed so that the rotating mechanism can drive the seat to rotate 180° or 360° relative to the mounting base 21 around the axis of rotation, or it can be adapted to actual needs. Preferably, the rotating mechanism 3 is designed to be able to drive the seat to rotate 90° to the left and right and then fix it. In this way, the maximum angle that the rotating mechanism 3 can rotate is 180°, which can meet the needs of most users. In order to make the rotating mechanism 3 able to drive the seat to rotate to the left and right and then fix it, at least three positioning holes 331 need to be opened on the mounting base 21. These three positioning holes 331 are located on the same circumference and are set at 90° intervals. In its normal state, the rotation adjustment component 33 engages with the positioning hole 331, locking the rotation mechanism 3 and preventing the seat from rotating. If seat rotation needs to be adjusted, the user applies external force to the rotation adjustment component 33, disengaging it from the positioning hole 331 and unlocking the rotation mechanism 3, allowing the seat to rotate. Furthermore, the adjustable seat structure may also include a height adjustment mechanism fixed to the chassis of the scooter. The base 1 is connected to the height adjustment mechanism, which allows adjustment of the overall seat height via holes. In summary, since the adjustable seat structure includes a moving mechanism 2 and a rotating mechanism 3, the mounting base 21 in the moving mechanism 2 can drive the rotating mechanism 3 to slide along the slide rail 11, adjusting the seat's proximity to or distance from the handlebars. Because the rotating mechanism 3 is rotatably connected to the mounting base 21, it can rotate around a pivot, causing the seat to rotate synchronously and adjusting the seat's rotation angle. The rotation adjustment component 3 enables locking and unlocking of the rotating mechanism 3. Therefore, the adjustable seat structure disclosed herein has both front-to-back and rotation adjustment functions, which is highly flexible, compact, and occupies little space. The base 1 can be detached from the frame.

[0032] In one embodiment, the rotating mechanism 3 includes a turntable 31 rotatably connected to the mounting base 21 and an elastic element 32 fixedly connected to the lower surface of the turntable 31. The elastic element 32 is connected to the mounting base 21 through a rotation adjustment assembly 33.

[0033] Specifically, in one embodiment, the elastic element 32 includes a fixed end 321 and a free end 322. The fixed end 321 is fixedly connected to the lower surface of the turntable 31 and can rotate with the turntable 31. The free end 322 is in contact with the mounting base 21.

[0034] In this embodiment, when the seat is positioned facing directly forward of the mobility scooter, the free end 322 of the elastic member 32 can face any direction—forward, backward, left, or right. For example, if the seat orientation and the free end 322 orientation are the same, both facing forward, then the three positioning holes 331 are respectively located on the surface of the mounting base 21 near the front end, near the left end, and near the right end to ensure that the turntable 31 can drive the seat to rotate left or right. If the seat orientation and the free end 322 orientation are opposite, then the three positioning holes 331 are respectively located on the surface of the mounting base 21 near the rear end, near the left end, and near the right end. When the seat faces forward and the free end 322 faces left or right, it is only necessary to ensure that the seat can rotate left or right, which will not be elaborated further here.

[0035] In one embodiment, the rotation adjustment assembly 33 includes a positioning part 332 disposed on the lower surface of the free end 322 and a handheld part 333 fixedly connected to the free end 322. When the rotation mechanism 3 is in the locked state, the positioning part 332 engages with the positioning hole 331; when an external force is applied to the handheld part 333, the elastic member 32 undergoes elastic deformation, causing the positioning part 332 and the positioning hole 331 to separate.

[0036] In this embodiment, when the elastic element 32 is in its free state, its free end 322 is attached to the mounting base 21. A positioning part 332 is fixed on the lower surface of the free end 322. The positioning part 332 passes through the positioning hole 331 and engages with it, thus locking the rotating mechanism 3 and preventing the seat from rotating. If it is necessary to adjust the seat rotation, the user applies external force to the hand-held part 333, causing the hand-held part 333 to drive the free end 322 of the elastic element 32 to undergo upward elastic deformation, thereby disengaging the positioning part 332 from the positioning hole 331 and unlocking the rotating mechanism 3. Then, the turntable 31 can be rotated to rotate the seat. Specifically, the positioning part 332 can be a positioning pin.

[0037] Reference Figure 4 As shown, in one embodiment, a first annular groove 211 is provided on the side of the mounting base 21 that cooperates with the turntable 31, and a second annular groove (not shown in the figure) is provided on the side of the turntable 31 that cooperates with the mounting base 21. The second annular groove corresponds to the first annular groove 211, and the first annular groove 211 and the second annular groove are connected by a rolling assembly.

[0038] In this embodiment, the turntable 31 and the mounting base 21 are fixed by riveting. The turntable 31 is provided with a threaded mounting hole, which can be connected to the bottom of the seat. The rolling assembly includes a plurality of balls 34, which are disposed between the first annular groove 211 and the second annular groove, thereby enabling the mounting base 21 and the turntable 31 to roll in cooperation to reduce friction.

[0039] In one embodiment, when the rotating mechanism 3 is in the locked state, the handheld part 333 and the mounting base 21 satisfy the parallel condition.

[0040] In this embodiment, when the rotating mechanism 3 is in the locked state, the free end 322 of the elastic element 32 is freely attached to the mounting base 21. By setting the hand-held part 333 parallel to the mounting base 21, it is convenient for the user to apply force to the hand-held part 333 to drive the free end 322 to undergo elastic deformation, so that the turntable 31 can rotate after the positioning pin leaves the positioning hole 331.

[0041] In one embodiment, a plurality of slots 212 are provided on the mounting base 21 along the moving direction of the mounting base 21. The plurality of slots 212 are located on the side of the mounting base 21 and can engage with the moving adjustment component 22 for limiting.

[0042] Specifically, in one embodiment, the movable adjustment component 22 includes a locking pin 221 rotatable about a rotation center, and a positioning block 223 is fixedly connected to the locking pin 221, the positioning block 223 engaging with the slot 212. The rotation center and the direction of movement are parallel.

[0043] In this embodiment, two bearing seats 13 are welded to one side of the base 1 where the movable adjustment assembly 22 is installed. A rotatable locking pin 221 with a handle 222 is inserted into each of the two bearing seats 13. A positioning block 223 is welded and fixed to the locking pin 221 located between the two bearing seats 13, and the positioning block 223 can engage with the slot 212. It is understood that the position on the positioning block 223 that engages with the slot 212 is contoured to the slot 212.

[0044] Furthermore, in one embodiment, the movable adjustment component 22 further includes an adjustment fixing part 224, which is disposed on the base 1, a locking pin 221 passes through the adjustment fixing part 224, and a positioning block 223 is located inside the adjustment fixing part 224.

[0045] In this embodiment, one of the two bearing seats 13 in the above embodiment is replaced by the adjustment fixing part 224, making the structure of the moving adjustment assembly 22 more stable and reliable.

[0046] In one embodiment, the movable adjustment assembly 22 further includes a torsion spring 225, which is sleeved on the locking pin 221 and connected to the adjustment fixing part 224.

[0047] In this embodiment, the torsion spring 225 serves as a reset mechanism. When the torsion spring 225 is in its initial state, the positioning block 223 engages with the slot 212. If it is necessary to unlock the mounting base 21 so that the mounting base 21 can move along the slide rail 11, the locking pin 221 needs to be rotated to make the positioning block 223 rotate away from the slot 212, thereby releasing the restriction on the mounting base 21. At this time, the torsion spring 225 undergoes elastic deformation. After the mounting base 21 is adjusted to the correct position, the external force is removed, and the torsion spring 225 resets, causing the positioning block 223 to engage with the slot 212.

[0048] In one embodiment, the base 1 is provided with a fixed baffle 14, which is fixed to the side of the slide rail 11 and covers part of the slide rail 11. A folding part 213 is provided at the connection between the mounting base 21 and the slide rail 11, and the folding part 213 is embedded between the fixed baffle 14 and the slide rail 11.

[0049] In this embodiment, the fixed baffle 14 covers a portion of the slide rail 11 to limit the folded portion 213 between the fixed baffle 14 and the slide rail 11, thereby longitudinally limiting the mounting base 21 and preventing it from falling off due to off-center load. Furthermore, the mounting base 21 is also provided with limiting screws to prevent it from detaching from the slide rail 11.

[0050] This disclosure also provides a mobility scooter equipped with an adjustable seat structure as described in any of the above-described embodiments.

[0051] In this embodiment, by providing an adjustable seat structure in the mobility scooter, the mounting base 21 in the moving mechanism 2 can drive the rotating mechanism 3 to slide along the slide rail 11 to adjust the seat to move closer to or further away from the handlebars. Since the turntable 31 is rotatably connected to the mounting base 21, it can rotate around the pivot, thereby driving the seat to rotate synchronously and adjusting the seat's rotation angle. By providing the elastic element 32 and the rotation adjustment component 33, the rotating mechanism 3 can be locked and unlocked. Thus, the adjustable seat structure of this disclosure has both front-to-back adjustment and rotation adjustment functions, is highly flexible, has a compact structure, occupies little space, and the base 1 can be detached from the frame.

[0052] In the description of this disclosure, it should be understood that the orientation or positional relationship indicated by directional terms is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this disclosure and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this disclosure; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0053] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," and "above" are used herein to describe the spatial positional relationship between one or more components or features shown in the figures and other components or features. It should be understood that spatial relative terms include not only the orientation of the component as depicted in the figures but also different orientations during use or operation. For example, if the components in the figures are inverted as a whole, "above" or "above other components or features" will include cases where the component is "below" or "under" other components or features. Thus, the exemplary term "above" can include both "above" and "below." Furthermore, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and this document intends to include all such cases.

[0054] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations according to this disclosure.
