Description

Technical Field

[0001] This disclosure relates to the field of mobility scooter technology, and more particularly to an adjustable seat structure and a mobility scooter. Background Technology

[0002] Currently, most scooters on the market only offer seat adjustment for rotation and height. Rotation is controlled by a lever under the seat support tube; pushing the lever upwards releases the limit, allowing the seat to rotate. However, this lever-based operation is prone to jamming, and the seat lacks forward and backward movement, failing to accommodate users of different heights and negatively impacting the user experience. 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] The moving mechanism includes a first seat support; and

[0006] The rotating mechanism includes a second seat support and a limiting component. The first seat support is slidably connected to the second seat support and the first seat support is slidable along the length direction of the second seat support. The second seat support is rotatably connected to the limiting component and the second seat support is rotatable about the axis of the limiting component.

[0007] In one possible implementation, a first locking mechanism is further included, which is disposed on the first seat support and can engage with the second seat support to limit and release the limit between the first seat support and the second seat support.

[0008] In one embodiment, the second seat support member is provided with a plurality of first limiting holes, which are spaced apart along the length direction of the second seat support member, and the first locking mechanism can engage with the first limiting holes.

[0009] In one embodiment, the first locking mechanism includes a first fixing sleeve, a first elastic component, and a first shaft connected to the first elastic component. The first fixing sleeve is fixed to the outside of the first seat support and is used to control the first elastic component to drive the first shaft to move axially along the first fixing sleeve. The first shaft passes through the first seat support and engages with the first limiting hole.

[0010] In one possible embodiment, a second locking mechanism is further included, which passes through the second seat support and can engage with the limiting component located within the second seat support, so that the second seat support and the limiting component can be limited and released from limitation.

[0011] In one embodiment, the limiting component includes a support for supporting the second seat support and a tube disposed on the support. The tube passes through the second seat support and is placed inside the second seat support. The tube has a plurality of second limiting holes in its circumferential direction, and the second locking mechanism can engage with the second limiting holes.

[0012] In one embodiment, the second locking mechanism includes a second fixed sleeve, a second elastic component, and a second shaft connected to the second elastic component. The second fixed sleeve is fixed to the outside of the second seat support and is used to control the second elastic component to drive the second shaft to move axially along the second fixed sleeve. The second shaft passes through the second seat support and engages with the second limiting hole.

[0013] In one embodiment, the support seat is provided with a first guide rail, the second seat support is provided with a first guide slide assembly, and the first guide slide assembly passes through the first guide rail.

[0014] In one embodiment, two sets of second guide rails are provided on the second seat support member along the length direction of the second seat support member. The two sets of second guide rails are respectively located on two side walls of the second seat support member and are symmetrically arranged. The first seat support member is provided with a second guide sliding assembly, which passes through the two sets of second guide rails. The second guide sliding assembly and the second guide rails are perpendicular to each other.

[0015] 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.

[0016] In this disclosure, the adjustable seat structure includes a moving mechanism and a rotating mechanism. The first seat support in the moving mechanism can support the seat and drive it to slide along the length of the second seat support to adjust the seat's proximity to or distance from the handlebars. Since the second seat support is rotatably connected to a limiting component, it can rotate around the axis of the limiting component, thereby causing the first seat support to rotate synchronously and adjust the seat angle. Therefore, the adjustable seat structure of this disclosure combines fore-and-aft adjustment with rotational adjustment, offering high flexibility and a compact structure that occupies little space.

[0027] 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.

[0028] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0029] Reference Figures 1-3 As shown, an exemplary embodiment of the present disclosure discloses an adjustable seat structure, including a moving mechanism 1 and a rotating mechanism 2. The moving mechanism 1 includes a first seat support 11, and the rotating mechanism 2 includes a second seat support 21 and a limiting component 22. The first seat support 11 and the second seat support 21 are slidably connected, and the first seat support 11 can slide along the length direction of the second seat support 21. The second seat support 21 is rotatably connected to the limiting component 22, and the second seat support 21 can rotate about the axis of the limiting component 22.

[0030] In this embodiment, the first seat support 11 supports the seat 221. The first seat support 11 has pre-drilled mounting holes for mounting seats of different sizes. It is understood 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 second seat support 21 is positioned directly in front of the vehicle and does not rotate, the sliding of the first seat support 11 along its length direction is equivalent to the first seat support 11 driving the seat to adjust forward and backward. After the seat is adjusted to its forward and backward position, the second seat support 21 can be rotated to rotate the seat to the left or right. The structure of the second seat support 21 and the limiting component 22 can be designed such that the second seat support 21 can rotate 180° or 360° around the axis of the limiting component 22, or it can be adapted to actual needs. Preferably, the second seat support 21 is designed to rotate 90° to the left and right, so that the maximum rotation angle of the second seat support 21 is 180°, which can meet the needs of most users. Furthermore, the adjustable seat structure may also include a height adjustment mechanism. The limiting component 22 is connected to the height adjustment mechanism, which is fixed to the chassis of the mobility scooter. The overall height of the seat can be adjusted through holes, which will not be elaborated further here. In summary, since the adjustable seat structure includes a moving mechanism 1 and a rotating mechanism 2, the first seat support 11 in the moving mechanism 1 can support the seat 221 and drive the seat to slide along the length of the second seat support 21 to adjust the seat to be closer to or further away from the handlebars. Since the second seat support 21 is rotatably connected to the limiting component 22, it can rotate around the axis of the limiting component 22, thereby driving the first seat support 11 to rotate synchronously and adjust the angle of the seat. The moving mechanism 1 and the rotating mechanism 2 can also be adjusted in height synchronously. Therefore, the adjustable seat structure disclosed herein has the functions of front-to-back adjustment, rotation adjustment, and height adjustment, which is highly flexible and compact in structure, occupying little space.

[0031] Reference Figures 4-6 As shown, in one embodiment, the adjustable seat structure further includes a first locking mechanism 3, which passes through the first seat support 11 and can engage with the second seat support 21, so that the first seat support 11 and the second seat support 21 can be limited and released from the limit.

[0032] Specifically, in one embodiment, the second seat support 21 is provided with a plurality of first limiting holes 211, which are spaced apart along the length of the second seat support 21, and the first locking mechanism 3 can engage with the first limiting holes 211.

[0033] Furthermore, in one embodiment, the first locking mechanism 3 includes a first fixing sleeve 31, a first elastic component 32, and a first shaft 33 connected to the first elastic component 32. The first fixing sleeve 31 is fixed to the outside of the first seat support 11 and is used to control the first elastic component 32 to drive the first shaft 33 to move axially along the first fixing sleeve 31. The first shaft 33 passes through the first seat support 11 and is engaged with the first limiting hole 211.

[0034] In this embodiment, taking the first locking mechanism 3 located on the left side of the adjustable seat structure as an example, the first fixing sleeve 31 is fixed to the outside of the first seat support 11. The first elastic component 32 includes a first pull rod and a first elastic element sleeved on the first pull rod. One end of the first elastic element is fixedly connected to the first pull rod, and the other end of the first elastic element is located inside the first fixing sleeve 31 and fixed relative to the first fixing sleeve 31. The first shaft 33 is fixedly connected to the first pull rod, so that when the user pulls the first pull rod, the first elastic element stretches, and the first pull rod drives the first shaft 33 to be pulled out from the first limiting hole 211, thereby releasing the restriction between the first seat support 11 and the second seat support 21 in their length direction, so that the first seat support 11 can be adjusted back and forth. After the first seat support 11 is adjusted to the correct position, the first pull rod is released, the first elastic element retracts and resets, and the first shaft 33 is inserted into the corresponding first limiting hole 211, thus re-limiting the first seat support 11 and the second seat support 21. Understandably, the number of first limiting holes 211 and the distance between two adjacent first limiting holes 211 can be adaptively designed according to actual needs, and the diameter of the first shaft 33 needs to match the first limiting holes 211, which is not limited here. However, it should be noted that the smaller the diameter of the first limiting hole 211, the thinner the first shaft 33 should be, which may result in insufficient strength of the first shaft 33. Therefore, appropriate selection is required during the design process.

[0035] In one embodiment, the adjustable seat structure further includes a second locking mechanism 4, which passes through the second seat support 21 and can engage with the limiting component 22 inside the second seat support 21, so that the second seat support 21 and the limiting component 22 can be limited and released from the limit.

[0036] Specifically, in one embodiment, the limiting component 22 includes a support seat 221 for supporting the second seat support 21 and a tube 222 fixed on the support seat 221. The tube 222 passes through the second seat support 21 and is placed inside the second seat support 21. The tube 222 has a plurality of second limiting holes 2221 in the circumferential direction, and the second locking mechanism 4 can engage with the second limiting holes 2221.

[0037] Furthermore, in one embodiment, the second locking mechanism 4 includes a second fixing sleeve 41, a second elastic component 42, and a second shaft 43 connected to the second elastic component 42. The second fixing sleeve 41 is fixed to the outside of the second seat support 21 and is used to control the second elastic component 42 to drive the second shaft 43 to move axially along the second fixing sleeve 41. The second shaft 43 passes through the second seat support 21 and is engaged with the second limiting hole 2221.

[0038] In this embodiment, taking the second locking mechanism 4 located on the right side of the adjustable seat structure as an example, the second fixing sleeve 41 is fixed to the outside of the second seat support 21. The second elastic component 42 includes a second pull rod and a second elastic element sleeved on the second pull rod. One end of the second elastic element is fixedly connected to the second pull rod, and the other end of the second elastic element is located inside the second fixing sleeve 41 and fixed relative to the second fixing sleeve 41. The second shaft 43 is fixedly connected to the second pull rod, so that when the user pulls the second pull rod, the second elastic element stretches, and the second pull rod drives the first shaft 33 to be pulled out from the second limiting hole 2221, thereby releasing the restriction between the second seat support 21 and the tube 222 in the circumferential direction of the tube 222, so that the second seat support 21 can be rotated and adjusted. After the second seat support 21 is adjusted to the correct position, the second pull rod is released, the second elastic element retracts and resets, and the second shaft 43 is inserted into the corresponding second limiting hole 2221, thus re-limiting the second seat support 21 and the tube 222. Understandably, the number of second limiting holes 2221 and the distance between two adjacent second limiting holes 2221 can be adaptively designed according to actual needs. Furthermore, the diameter of the second shaft 43 needs to match the second limiting holes 2221. For example, one second limiting hole 2221 can be set every 45° along the circumference of the pipe fitting 222, resulting in 8 second limiting holes 2221. Alternatively, one second limiting hole 2221 can be set every 30° along the critical circumference, resulting in 12 second limiting holes 2221. However, it should be noted that the smaller the diameter of the second limiting hole 2221, the thinner the second shaft 43 should be, potentially leading to insufficient strength of the second shaft 43. Therefore, appropriate selection is necessary during the design process.

[0039] In one embodiment, a first guide rail 2211 is provided on the support seat 221, and a first guide slide assembly 5 is provided on the second seat support 21, with the first guide slide assembly 5 passing through the first guide rail 2211.

[0040] In this embodiment, the first guide rail 2211 is generally arc-shaped. Taking the design of the second seat support 21, which can rotate 90° to the left and right, as an example, the first guide rail 2211 is a semi-circular arc. However, if the second seat support 21 can rotate 360°, the first guide rail 2211 is generally circular. The first guide slide assembly 5 includes a first shoulder bolt disposed on the second seat support 21 and passing through the first guide rail 2211. A first plastic washer 7 is disposed between the first shoulder bolt and the second seat support 21 to ensure the flexibility of the second seat support 21 during rotation and prevent jamming.

[0041] In one embodiment, two sets of second guide rails 212 are provided on the second seat support 21 along its length. The two sets of second guide rails 212 are located on two side walls of the second seat support 21 and are symmetrically arranged. A second guide slide assembly 6 is provided on the first seat support 11, and the second guide slide assembly 6 passes through the two sets of second guide rails 212. The second guide slide assembly 6 and the second guide rails 212 are perpendicular.

[0042] In this embodiment, the second guide slide assembly 6 includes a second shoulder bolt disposed on the first seat support 11 and passing through the two sets of second guide rails 212. A second plastic washer 8 is sleeved on the second shoulder bolt. The second plastic washer 8 is located between the first seat support 11 and the second seat support 21 to ensure the flexibility of relative sliding between the first seat support 11 and the second seat support 21 and prevent jamming.

[0043] This disclosure also provides a mobility scooter equipped with an adjustable seat structure as described in any of the above-described embodiments.

[0044] In this embodiment, by setting an adjustable seat structure in the mobility scooter, the first seat support 11 in the moving mechanism 1 can support the seat 221 and drive the seat to slide along the length direction of the second seat support 21 to adjust the seat to move closer to or further away from the handlebars; since the second seat support 21 is rotatably connected to the limiting component 22, it can rotate around the axis of the limiting component 22, thereby driving the first seat support 11 to rotate synchronously and adjust the angle of the seat, so that the mobility scooter has both front-to-back adjustment and rotation adjustment functions, which is highly flexible and has a compact structure that occupies little space.

[0045] 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.

[0046] 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.
