Description

Technical Field

[0001] This utility model relates to the field of transportation technology, and in particular to a folding seat and a scooter. Background Technology

[0002] With the widespread use of electric scooters for short-distance urban commuting, their portability and flexibility are increasingly favored by consumers. Traditional scooters mainly consist of a frame, wheels, handlebars, and pedals. Users stand on the pedals and control the handlebars to move and steer. Due to the limited riding posture, users' legs need to continuously bear the weight of their body during long rides, which can easily lead to fatigue and soreness.

[0003] To address these issues, scooters equipped with seats have emerged in the market in recent years, aiming to alleviate leg pressure and improve riding comfort by providing a seated riding posture. However, these scooters with folding seats introduce new problems in actual use: when the user returns to standing riding, the seat needs to be folded for storage. However, existing folding seats are located on the side of the frame facing the user when folded, affecting the length of the user's standing area and making it inconvenient for users to hang items on the scooter, thus impacting the overall user experience.

Detailed Implementation

[0021] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and 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 of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 according to the specific circumstances.

[0024] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0025] The first aspect of this utility model is to provide a folding seat, such as Figure 1 and Figure 3 As shown, it includes a sleeve 1, a rotating tube 2, a rotating arm 3, and a seat cushion assembly 4; The rotating tube 2 is rotatably sleeved on the outside of the sleeve 1. A first adjusting component 5 is provided between the rotating tube 2 and the sleeve 1. The first adjusting component 5 is configured to adjust and lock the angle of the rotating tube 2 relative to the sleeve 1. The two ends of the rotating arm 3 are rotatably connected to the rotating tube 2 and the seat cushion assembly 4, respectively. The rotating arm 3 and the seat cushion assembly 4 have an unfolded state and a folded state relative to the rotating tube 2.

[0026] When the user needs to use the seat assembly 4 for riding, the seat assembly 4 can be adjusted to the unfolded state. At this time, the first adjustment component 5 locks the angle of the rotating tube 2 relative to the sleeve 1. When the seat assembly 4 is not needed, the angle of the rotating tube 2 relative to the sleeve 1 can be adjusted by the first adjustment component 5 so that the seat assembly 4 avoids the user's standing area. After the adjustment is completed, the angle of the rotating tube 2 relative to the sleeve 1 can be locked by the first adjustment component 5, and then the seat assembly 4 can be adjusted to the folded state.

[0027] Therefore, the seat cushion component 4 in the folding seat can avoid the user's standing area when folded, without affecting the length of the standing area. The user has more standing space and space to hang items, resulting in a better user experience.

[0028] To ensure that sleeve 1 can stably support rotating tube 2, such as Figure 2 As shown, the bottom end of the sleeve 1 is provided with a boss 11, which protrudes from the outer circumference of the sleeve 1. The bottom end of the rotating tube 2 can be attached to the boss 11, which can fully support the rotating tube 2 and prevent the rotating tube 2 from falling off the sleeve 1 during use.

[0029] It should be noted that any structure capable of adjusting and locking the angle of the rotating tube 2 relative to the sleeve 1 can be the first adjusting component 5 mentioned in the above embodiments. For example, the first adjusting component 5 includes a locking nut that passes through the rotating tube 2 and abuts against the outer wall of the sleeve 1. Tightening the locking nut increases the friction between the locking nut and the sleeve 1, thereby locking the angle. Loosening the locking nut reduces the friction between the locking nut and the sleeve 1, thereby adjusting the angle. Alternatively, the first adjusting component 5 includes an elastic protrusion on the inner wall of the rotating tube 2 and multiple slots on the outer wall of the sleeve 1. The slots are spaced apart circumferentially along the sleeve 1, and the elastic protrusion can engage with any one of the slots to achieve angle adjustment and locking.

[0030] Of course, the above is just one example of the optional structure of the first adjustment component 5, and the structure of the first adjustment component 5 is not limited to the above two.

[0031] In an optional embodiment, to facilitate user operation, the first adjustment component 5 includes a plurality of first snap-fit ​​structures and a second snap-fit ​​structure for snapping with any one of the first snap-fit ​​structures; one of the sleeve 1 and the rotating tube 2 is provided with each of the first snap-fit ​​structures at intervals along its circumference, and the other is provided with the second snap-fit ​​structure.

[0032] In the above embodiments, the sleeve 1 and the rotating tube 2 can lock the angle of the rotating tube 2 relative to the sleeve 1 by the snap-fit ​​between the first snap-fit ​​structure and the second snap-fit ​​structure. The angle of the rotating tube 2 relative to the sleeve 1 can be adjusted by canceling the snap-fit ​​between the two. Compared with bolts and other connecting parts, the snap-fit ​​structure can be directly formed on the rotating tube 2 and the sleeve 1, which is convenient for the assembly of the two and will not result in the loss of connecting parts. It is also convenient for the user to operate.

[0033] In the above embodiments, the first snap-fit ​​structure is configured in multiple ways, specifically two, three, four, etc.

[0034] Specifically, the interval between any two adjacent first snap-fit ​​structures is 180 / n°, where n is a positive integer. This arrangement allows the seat cushion assembly 4 to rotate 180° along the direction of travel to be positioned directly in front of the sleeve 1 when the user is not using the seat cushion assembly 4, without occupying the user's standing area.

[0035] The first snap-fit ​​structure is preferably configured as two, with the two first snap-fit ​​structures spaced 180° apart. One first snap-fit ​​structure is located on the side of the sleeve 1 facing the user when in use, and the other first snap-fit ​​structure is located on the side of the sleeve 1 away from the user when in use.

[0036] Specifically, the second snap-fit ​​structure can be configured as one or multiple. When the second snap-fit ​​structure is configured as one, it can be selectively snapped onto any one of the first snap-fit ​​structures. When the second snap-fit ​​structure is snapped onto different first snap-fit ​​structures, the seat cushion assembly 4 will be located in different positions of the sleeve 1.

[0037] When multiple second snap-fit ​​structures are configured, if one of the second snap-fit ​​structures snaps into any one of the first snap-fit ​​structures, the remaining second snap-fit ​​structures can snap into the remaining first snap-fit ​​structures, thus forming multiple snap-fit ​​points between the rotating pipe 2 and the sleeve 1, ensuring the stability of their circumferential positions.

[0038] The above-described embodiments enable each of the first snap-fit ​​structures to snap into each of the second snap-fit ​​structures in a one-to-one correspondence, thereby stably locking the angle of the rotating tube 2 relative to the sleeve 1.

[0039] In an optional embodiment, one of the first snap-fit ​​structure and the second snap-fit ​​structure includes a slot 51 and the other includes a protrusion 52. The slot 51 has an opening at one end along the axial direction of the rotating tube 2 for the protrusion 52 to enter and exit.

[0040] In the above embodiment, since the slot 51 has an opening for the protrusion 52 to enter and exit at one end along the axial direction of the rotating tube 2, the user can first move the rotating tube 2 relative to the sleeve 1 along the axial direction of the sleeve 1 to make the protrusion 52 exit the slot 51, and finally rotate the rotating tube 2 to a suitable position, and then make the protrusion 52 enter the slot 51 along the axial direction of the rotating tube 2 to lock the angle of the rotating tube 2 relative to the sleeve 1.

[0041] The advantages of the above setting are: by moving the rotating tube 2 axially along the rotating tube 2 and rotating the rotating tube 2 circumferentially along the sleeve 1, the angle of the rotating tube 2 relative to the sleeve 1 can be adjusted, which is convenient for the user to operate. Moreover, the above setting does not require the protrusion 52 to be made of elastic material. The protrusion 52 and the slot 51 can both be made of rigid material, making the locking between the rotating tube 2 and the sleeve 1 more secure.

[0042] The above embodiments do not limit which of the slot 51 and the protrusion 52 is provided on the sleeve 1 and which is provided on the rotating tube 2. That is, the sleeve 1 may be provided with the slot 51 and the rotating tube 2 may be provided with the protrusion 52, and at least one of the slot 51 and the protrusion 52 may be configured as multiple; or the sleeve 1 may be provided with the protrusion 52 and the rotating tube 2 may be provided with the slot 51, and at least one of the slot 51 and the protrusion 52 may be configured as multiple.

[0043] Users can choose from the various implementation methods described above as needed.

[0044] by Figure 2For example, a protrusion 52 is provided on the sleeve 1. When the sleeve 1 is assembled, the protrusion 52 faces the rider. The rotating tube 2 is provided with multiple slots 51. The bottom end of the slot along the axial direction of the rotating tube 2 has an opening for the protrusion 52 to enter and exit. Preferably, there are two slots 51, which are spaced 180° apart. One slot 51 is positioned facing the seat assembly 4, and the other slot 51 is positioned away from the seat assembly 4.

[0045] When the user needs to use the saddle assembly 4 for riding, the protrusion 52 is engaged in the slot 51 provided in front of the saddle assembly 4, and the saddle assembly 4 can be used by the rider. When the saddle assembly 4 is not needed, the saddle assembly 4 is folded, the rotating tube 2 is moved up and rotated 180°, and then the protrusion 52 is engaged in the slot 51 provided behind the saddle assembly 4. The saddle assembly 4 avoids the user's standing area and is located in front of the sleeve 1 along the direction of travel.

[0046] In alternative implementations, such as Figure 1 As shown, in order to ensure that the rotating arm 3 can be stably kept in the extended state, the outer wall of the rotating tube 2 is provided with a first limiting member 21 located below the rotating arm 3.

[0047] It is understandable that "the outer wall of the rotating tube 2 is provided with a first limiting member 21 located below the rotating arm 3" means that when the folding seat is in use while the vehicle is in motion, the first limiting member 21 is located below the rotating arm 3. At this time, the first limiting member 21 can prevent the rotating arm 3 from rotating downward relative to the rotating tube 2, and play a supporting role for the rotating arm 3 to ensure the stability of the folding seat.

[0048] Specifically, the end of the rotating arm 3 away from the seat cushion assembly 4 is hinged to the shaft on the rotating tube 2, and the first limiting member 21 is located below the shaft. In the unfolded state, the aforementioned end of the rotating arm 3 can be attached to the first limiting member 21.

[0049] The first limiting component 21 mentioned above can be a limiting block, a limiting plate, a limiting pin, or any structure that can support the rotating arm 3.

[0050] The first limiting member 21 can be welded to the rotating tube 2, or threaded to the rotating tube 2, or interference-fitted to the rotating tube 2, or integrally formed with the rotating tube 2.

[0051] When the folding seat is in use and the first limiting member 21 is located below the rotating arm 3, preventing the rotating arm 3 from rotating downward relative to the rotating tube 2, in order to ensure that the seat assembly 4 can remain in the unfolded state and stably support the rider, the seat assembly 4 can be installed on the support structure of the scooter, and the support structure supports the seat assembly 4 and the rider on the seat assembly 4.

[0052] In alternative implementations, such as Figure 1 As shown, in order to ensure that the seat cushion assembly 4 can be stably kept in the unfolded state, the end of the rotating arm 3 away from the rotating tube 2 is provided with a second limiting member 31, which is located below the seat cushion assembly 4.

[0053] It is understandable that "the second limiting member 31 is located below the seat cushion assembly 4" means that when the seat is folded down and in motion, the second limiting member 31 is located below the seat cushion assembly 4. At this time, the second limiting member 31 abuts against the seat cushion assembly 4 to support the seat cushion assembly 4 in the unfolded state and ensure the stability of the seat cushion assembly 4.

[0054] Specifically, such as Figure 2 As shown, the end of the rotating arm 3 away from the rotating tube 2 is hinged to one end of the seat cushion assembly 4 via the rotating shaft 10. In the unfolded state, the aforementioned end of the seat cushion assembly 4 can be attached to the second limiting member 31.

[0055] The aforementioned second limiting component 31 can be a limiting block, limiting plate, limiting pin, or any structure that can support the seat cushion assembly 4.

[0056] like Figure 2 As shown, the second limiting member 31 is approximately bent into an "L" shape, with the bend being arc-shaped, so that the extension direction of the bend can match the shape of the end of the seat cushion assembly 4, increasing the contact area between the seat cushion assembly and the second limiting member 31, thereby achieving a better support effect.

[0057] Similarly, based on the above implementation method, when the first limiting member 21 is not provided, the seat assembly 4 can also be installed on the support structure of the scooter, and the support structure can support the seat assembly 4 and the rider on the seat assembly 4 to maintain the stability of the position of the seat assembly 4.

[0058] Of course, preferably, the outer wall of the rotating tube 2 is provided with the first limiting member 21, and the end of the rotating arm 3 away from the rotating tube 2 is provided with the second limiting member 31.

[0059] In an optional embodiment, in order to ensure that the seat cushion assembly 4 can be stably in a folded state, a limiting component is provided between the end of the rotating arm 3 away from the rotating tube 2 and the seat cushion assembly 4, and the limiting component is configured to support the seat cushion assembly 4 in a folded state.

[0060] The aforementioned limiting components may include a slot and a locking block that engages with the slot, or may include a clamping claw that supports the seat cushion assembly 4 in a folded state by clamping it, etc.

[0061] like Figure 2As shown, the limiting component may include a first notch 32 opened on the edge of the rotating arm 3 and a locking block 411 disposed on the seat cushion assembly 4. When the seat cushion assembly 4 rotates to a folded state relative to the rotating arm 3, the locking block 411 can just engage with the first notch 32, thereby limiting the position of the seat cushion assembly 4 relative to the rotating arm 3.

[0062] Of course, the edge of the rotating arm 3 may also have a second notch 33. When the seat cushion assembly 4 rotates to the unfolded state relative to the rotating arm 3, the locking block 411 can just be locked into the second notch 33, thereby limiting the position of the seat cushion assembly 4 relative to the rotating arm 3.

[0063] It should also be mentioned that the rotating arm 3 can be configured as one, or as two, three, or more. For example... Figure 2 As shown, in order to enable the rotating arm 3 to effectively support the seat cushion assembly 4, two rotating arms 3 are configured, which are relatively parallel and spaced apart, and the seat cushion assembly 4 is hinged to the outside of the two rotating arms 3.

[0064] It should be noted that the seat assembly 4 can adopt a fixed seat structure. Of course, to meet the riding posture of different users, in an optional embodiment, the seat assembly 4 includes a first support 41, a second support 42, and a seat 43; the first support 41 is rotatably connected to the rotating arm 3, and the axis of rotation is perpendicular to the axis of the rotating tube 2; the second support 42 is slidably engaged with the first support 41 in the front-back direction; a second adjustment component 44 is provided between the second support 42 and the first support 41, and the second adjustment component 44 is configured to adjust and lock the sliding position of the second support 42 relative to the first support 41; the seat 43 is installed on the second support 42.

[0065] When in use, the user can adjust the front and back position of the second support 42 relative to the first support 41 by using the second adjustment component 44 according to their own height, leg length and sitting posture habits, thereby adjusting the front and back position of the seat cushion 43 to obtain the best support effect and riding comfort.

[0066] It is understandable that the aforementioned front-to-back direction refers to the direction between the front and rear of the vehicle after the folding seats are installed on the vehicle body, with the part closer to the front being the front and the part closer to the rear being the rear.

[0067] Specifically, the second bracket 42 is provided with a sliding groove 421, and the first bracket 41 is provided with a slider 412 that slides in cooperation with the sliding groove 421.

[0068] It should be noted that any structure capable of adjusting and locking the sliding position of the second bracket 42 relative to the first bracket 41 can be the second adjustment component 44 mentioned in the above embodiments. For example, the second adjustment component 44 may include a bolt and a nut, wherein the bolt passes through the first bracket 41 and the second bracket 42, and the nut is screwed onto the bolt, and its locking state is controlled by the nut: when the nut is loosened, the second bracket 42 is allowed to slide freely in the front-back direction; when the nut is tightened, the bolt and nut can fix the second bracket 42 to a certain position on the first bracket 41.

[0069] Or such as Figure 2 As shown, the second adjustment assembly 44 includes a locking member 441 and an elastic member 442; the locking member 441 is slidably engaged with the second bracket 42. Specifically, the locking member 441 can slide linearly along a groove or guide structure on the second bracket 42, with its sliding direction perpendicular to the sliding direction of the first bracket 41 relative to the second bracket 42. Thus, the locking member 441 can form a lateral locking force at its contact surface with the first bracket 41, thereby effectively preventing the second bracket 42 from shifting in the non-operating state.

[0070] The elastic member 442 is located between the locking member 441 and the second bracket 42. The elastic member 442 is configured to apply a spring force to the locking member 441 toward the first bracket 41 so that the locking member 441 engages with the first bracket 41 and locks the position of the first bracket 41 relative to the second bracket 42.

[0071] When the locking member 441 contacts the first bracket 41 under the action of the elastic member 442, a locking engagement is formed between the two, thereby restricting the movement of the first bracket 41 relative to the second bracket 42 and realizing the position locking function. The user can manually operate the locking member 441 to overcome the elastic force of the elastic member 442, causing the locking member 441 to disengage from the engagement state with the first bracket 41, thereby unlocking the first bracket 41 and allowing it to move freely in its sliding direction to realize the adjustment function.

[0072] The elastic element 442 is preferably a spring, but is not limited to a spring; it can also be other elastic structures with a reset function.

[0073] In the above embodiment, by configuring the locking member 441 and the second bracket 42 in a sliding fit, and making its sliding direction perpendicular to the sliding direction of the first bracket 41, a reasonable spatial structure layout can be effectively achieved, improving the stability and reliability of the locking. At the same time, the elastic member 442 not only simplifies the operation but also enhances the structure's automatic reset capability, improving the user experience.

[0074] When the locking member 441 contacts the first bracket 41 under the action of the elastic member 442, the locking member 441 and the first bracket 41 can form a locking engagement through friction, or the locking engagement can be achieved through a snap-fit ​​structure, magnetic structure, etc.

[0075] In alternative implementations, such as Figure 4 As shown, the first bracket 41 is provided with a first locking structure 413, and the locking member 441 is provided with a second locking structure 4411. The second locking structure 4411 is configured to cooperate with the first locking structure 413 to lock the position of the first bracket 41 relative to the second bracket 42 under the elastic force of the elastic member 442.

[0076] In the above embodiments, the position of the first bracket 41 relative to the second bracket 42 is locked by the cooperation of the first locking structure 413 and the second locking structure 4411. Compared with locking by friction, this can more effectively ensure the locking state of the two, and at the same time, it does not require the elastic member 442 to apply a large elastic force to the locking member 441.

[0077] Specifically, such as Figure 2 and Figure 4 As shown, the first support 41 can be strip-shaped, and the second support 42 includes a top plate 422, a bottom plate 423 and a side plate 424 connecting the top plate 422 and the bottom plate 423. The top plate 422 and the bottom plate 423 are arranged opposite each other, and the sliding groove 421 is provided on the side plate 424.

[0078] Additionally, the locking member 441 may include a first plate 4412 and a second plate 4413 perpendicularly connected to the first plate 4412. The second plate 4413 passes through an opening in the side plate 424, such that one end of the first plate 4412 is located between the top plate 422 and the bottom plate 423, and the end of the second plate 4413 away from the first plate 4412 extends to the outside of the side plate 424 for easy operation by the user. A first bracket 41 is located above the locking member 441, and a first locking structure 413 is provided at the lower edge of the first bracket 41, while a second locking structure 4411 is provided at the upper end of the first plate 4412.

[0079] The elastic element 442 can be disposed between the bottom surface of the second plate 4413 and the bottom plate 423. In use, the user can overcome the elastic force of the elastic element 442 and press down on the second plate 4413. The elastic element 442 is compressed, releasing the lock between the first bracket 41 and the second bracket 42. After the second plate 4413 is released, the elastic element 442 releases its elastic force and lifts the second plate 4413, so that the first plate 4412 and the first bracket 41 cooperate. Alternatively, the elastic element 442 can be disposed between the top surface of the second plate 4413 and the top plate 422. In use, the user can overcome the elastic force of the elastic element 442 and press down on the second plate 4413. The elastic element 442 is stretched, releasing the lock between the first bracket 41 and the second bracket 42. After the second plate 4413 is released, the elastic element 442 releases its elastic force and pulls the second plate 4413 up, so that the first plate 4412 and the first bracket 41 cooperate.

[0080] In an optional embodiment, along the sliding direction of the second bracket 42 relative to the first bracket 41, the first locking structure 413 includes a plurality of teeth disposed on the first bracket 41, and the second locking structure 4411 includes a slot disposed on the locking member 441. The slot can cooperate with any one of the teeth to achieve the locking member 441 and the first bracket 41 being engaged.

[0081] Alternatively, the locking element 441 may have locking teeth, and the first bracket 41 may have multiple locking slots.

[0082] Furthermore, the aforementioned first bracket 41 and second bracket 42 can be configured as one, or as two, three, or more. For example... Figure 2 As shown, in order to enable the first support 41 and the second support 42 to effectively support the seat cushion 43, two first supports 41 and two second supports 42 are configured. The two first supports 41 are located inside the two second supports 42, and a second adjustment component 44 may be provided between one of the second supports 42 and one of the first supports 41.

[0083] A second aspect of this utility model provides a scooter, such as Figure 5 As shown, the scooter provided in the second aspect of this utility model includes a riser 6 and the aforementioned folding seat, with a sleeve 1 fitted onto the outside of the riser 6.

[0084] The scooter provided in the second aspect of this utility model has a folding seat provided in the first aspect of this utility model, thereby having all the beneficial effects of the folding seat provided in the first aspect of this utility model.

[0085] In an optional embodiment, a third adjustment component is provided between the riser 6 and the sleeve 1, the third adjustment component being configured to adjust the height of the sleeve 1 relative to the riser 6.

[0086] The third adjustment component allows the sleeve 1 to move along the axial direction of the riser 6 and to be locked at any height, thereby enabling flexible adjustment of the installation height of the sleeve 1 to adapt to different usage scenarios or user needs.

[0087] The third adjustment component includes, but is not limited to, one or more combinations of an adjustment screw, a limiting slide, an elastic buckle, or a hydraulic lifting structure. For example, in a preferred embodiment, the third adjustment component includes a limiting screw 011 disposed below the sleeve 1 and a plurality of mounting holes disposed on the outer wall of the riser 6 for inserting the limiting screw 011. The mounting holes are spaced apart along the axial direction of the riser. When it is necessary to adjust the height of the seat cushion assembly 4, the position of the limiting screw 011 can be changed to adjust the seat height.

[0088] In alternative implementations, such as Figure 5 and Figure 6 As shown, the scooter also includes a footboard 7, a first support rod 8, and a second support rod 9. One end of both the first support rod 8 and the second support rod 9 is rotatably connected to the footboard 7, with the rotation axis horizontally positioned and perpendicular to the scooter's direction of travel. This allows the first and second support rods 8 and 9 to be folded or unfolded relative to the footboard 7, facilitating carrying and storage for the user. The other end of the first support rod 8 is detachably connected to the seat assembly 4, allowing the user to disconnect the first support rod 8 from the second bracket 42 in the seat assembly 4 as needed, adapting to different usage scenarios. The other end of the second support rod 9 is detachably connected to the first support rod 8, specifically at the middle of the first support rod 8, forming a stable triangular support structure in the unfolded state, improving the scooter's structural stability and load-bearing capacity during use.

[0089] The aforementioned detachable connection methods can include bolt connection, snap-fit ​​connection, pin connection, etc.

[0090] The footboard 7 has a storage slot for accommodating the first support rod 8 and the second support rod 9. The shape and size of the storage slot are adapted to the shape of the first support rod 8 and the second support rod 9, so that in the folded state, the first support rod 8 and the second support rod 9 can be completely embedded in the storage slot, avoiding protrusion from the surface of the footboard 7, thus improving the overall aesthetics and portability of the scooter.

[0091] Preferably, the storage slot may be provided with an elastic buckle structure or a limiting groove to fix the first support rod 8 and the second support rod 9 in the storage state, so as to prevent them from shaking or falling off during carrying.

[0092] Through the above structural design, the scooter not only allows the seat component 4 to be detached, but also has the function of folding and storing the support structure, which significantly improves the portability and versatility of the scooter and meets the needs of different user groups in various usage scenarios.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
