Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of scooters, in particular to a foldable scooter and a folding method thereof. BACKGROUND

[0002] With the acceleration of urbanization and the popularization of green travel concept, short-distance scooters have become the core carrier for connecting public transportation and relieving urban travel pressure. Among them, folding scooters are widely praised by the market because they can flexibly adapt to the storage and transportation needs of multiple scenes such as families, subways, and car trunks. Although the current folding scooters have realized basic portable functions, the technical bottlenecks in actual application are still quite prominent. Most existing products use segmented folding design, which not only has complex structure and cumbersome operation process, but also often fails to achieve synchronous linkage of the frame, seat and backrest during folding, significantly affecting the use efficiency and convenient experience. At the same time, users' demand for scooter operation simplicity and structural stability continues to upgrade, and the traditional folding mechanism needs to be unlocked in multiple steps, which has the disadvantages of structural redundancy and cumbersome operation. Under this background, it is necessary to optimize the folding structure design, realize synchronous folding of the frame, seat cushion and backrest by simplifying the transmission logic, and consider the core needs of operation convenience, structural reliability and lightweight, to help folding scooters realize technical iteration and upgrading. SUMMARY

[0003] The technical problem solved by the present application is to provide a foldable scooter and a folding method thereof to solve the problems raised in the background.

[0004] According to an aspect of an embodiment of the present application, a foldable scooter and a folding method thereof are provided. The folding method of the scooter includes a manual folding method using a frame fixing assembly as a locking assembly and an electric folding method using an electric telescopic rod as a locking assembly, wherein the manual folding method is the main discussion scheme of the present application. The scooter of the manual folding method includes a bottom frame, a steering assembly, a front wheel, a rear wheel group, a seat assembly, a seat folding rod group, a rear wheel connecting rod group, a folding assembly, and a frame fixing assembly. The scooter corresponding to the electric folding method only replaces the frame fixing assembly in the manual scheme with an electric telescopic rod, and the remaining components and connection relationships are consistent with those of the manual scheme.

[0005] The folding assembly and the steering assembly are connected to the bottom frame. The rear wheel group is connected to the folding assembly through the rear wheel connecting rod group. The seat assembly includes a seat cushion and a backrest, and is connected to the folding assembly through the seat folding rod group. The steering assembly is assembled at the front end of the bottom frame, and the frame fixing assembly is fixedly connected to the bottom frame.

[0006] Furthermore, the chassis includes a vertical pole and a main pole connected together. A foot pedal assembly is provided on the side of the vertical pole. A steering assembly is installed inside the vertical pole. The front wheel is installed at the lower end of the vertical pole and connected to the steering assembly through the vertical pole. A folding assembly is installed on the main pole. A frame fixing assembly is fixedly installed on the main pole.

[0007] Furthermore, the steering assembly includes a handle, a steering column, and a latch. The handle is mounted on one end of the steering column, the latch is mounted on the other end of the steering column and together they are mounted on the column of the vehicle chassis. The front wheel is mounted on the lower end of the column and is connected to the steering column via the column.

[0008] Furthermore, the folding assembly includes a slider, a fixing member, and a sliding kit. The sliding kit is embedded and fixedly assembled inside the slider. The slider can slide along the axial direction of the main rod. The fixing member is fixedly assembled to one end of the main rod, forming a reference fulcrum for folding linkage.

[0009] Furthermore, the rear wheel connecting rod assembly is hinged to one end of the sliding and fixing parts of the folding assembly, and the seat folding rod assembly is hinged to the other end of the sliding and fixing parts of the folding assembly, forming a linkage folding structure.

[0010] Furthermore, the rear wheel assembly includes two rear wheels, and the rear wheel connecting rod assembly includes two pairs of connecting rods. The two ends of each pair of connecting rods are respectively hinged to the sliding member and the fixing member of the folding assembly. The rear wheels are linked to the folding assembly through the connecting rods.

[0011] Furthermore, the seat assembly includes a seat cushion and a backrest hinged thereto, and the seat folding rod assembly includes two sets of folding rods hinged to each other and a pair of backrest folding members; the two ends of the two sets of folding rods are respectively hinged to the folding assembly and the seat cushion, and the two ends of the backrest folding members are hinged to the folding rods and the backrest; the seat cushion and the backrest are linked to the seat folding rod assembly through multiple sets of hinge structures.

[0012] Furthermore, the frame fixing component of the scooter using the manual folding method includes a button and a beaded snap fastener. The main rod of the chassis frame has at least one functional hole that mates with the frame fixing component. The sliding member and the sliding kit embedded thereon have positioning holes for fixed engagement. The button is fixedly installed on the main rod, and the beaded snap fastener is embedded inside the main rod. The beaded snap fastener forms a linkage engagement structure with the button through the functional hole on the main rod. Pressing the button transmits a downward pressing action to the beaded snap fastener, which can drive the beaded snap fastener to fall and spring up, thereby locking or unlocking the sliding member of the folding component on the main rod, so that the sliding member is stably kept in a fixed state or slides freely along the main rod, thereby controlling the unfolding or folding of the frame.

[0013] Optionally, the main rod of the chassis of the mobility scooter in the manual folding method may have one or more functional holes that cooperate with the frame fixing components, and the corresponding beaded snap fasteners may be single or multiple beads; the purpose of cooperation can be achieved through operation methods with equivalent effects. This application preferably uses a method of cooperation with two functional holes, and operation methods with other numbers of holes that have similar functions should also be included in the protection scope of this application.

[0014] Optionally, in the electric folding method of the mobility scooter, the electric telescopic rod is fixedly assembled inside the main rod, and a sliding groove is provided on the lower side of the main rod. The telescopic end of the electric telescopic rod is fixedly connected to the sliding component through the sliding groove. Controlling the extension and retraction of the electric telescopic rod can drive the sliding component to move along the sliding groove, and synchronously control the unfolding and folding of the frame.

[0015] Optionally, the backrest and backrest folding component in the seat folding rod assembly can be eliminated, allowing the mobility scooter to fold only the rear wheel assembly and seat cushion. This reduces the number of parts in the mobility scooter and decreases its folded volume and weight.

[0016] When folding, first unlock the locking assembly to allow the slider to return to its free sliding state along the main rod axis; push the slider to move along the main rod axis, gradually moving it away from the fixed part; since the rear wheel connecting rod assembly is hinged to one end of the slider and one end of the fixed part respectively, when the slider moves away from the fixed part, the rear wheel connecting rod assembly simultaneously drives the rear wheel assembly to fold; at the same time, the two ends of the seat folding rod assembly are respectively hinged to the other ends of the seat cushion and the slider and fixed part, and the backrest is linked to the seat folding rod assembly through the backrest folding part and hinged to the seat cushion. When the slider moves, it simultaneously drives the seat cushion and backrest to fold; finally, fold the steering assembly and foot pedal assembly to complete the overall folding and storage of the mobility scooter.

[0017] In addition to the core storage method of folding the rear wheel assembly, seat cushion, and backrest simultaneously as described above, this application also supports a folding method that folds only the rear wheel assembly and seat cushion simultaneously. This solution eliminates the backrest without affecting the linkage effect of other folding mechanisms.

[0018] The beneficial effects of this application are as follows: by cleverly connecting the folding components and each folding rod group, a linkage folding structure is constructed. Only one core sliding operation is required to drive the rear wheel group, seat cushion and backrest to fold synchronously. Compared with traditional technology, the operation steps are greatly simplified, and the multi-step folding process is streamlined into a one-click folding effect. At the same time, the structural design is optimized to reduce the number of parts, effectively reduce the weight of the device and the volume after folding, improve the ease of operation and storage practicality, and solve the technical pain points of traditional mobility scooters, such as cumbersome folding, large size and redundant structure.

[0039] This application provides a foldable mobility scooter and its folding method. Please refer to the following for details. Figures 1 to 4 Taking the manual folding method as an example, this mobility scooter includes a chassis 1, a steering assembly 2 connected to the upright 12 of the chassis 1, a front wheel 3 located below the upright 12 of the chassis 1, a folding assembly 8 mounted on the main rod 11 of the chassis 1, a rear wheel connecting rod assembly 7 hinged at both ends to the folding assembly 8, a rear wheel assembly 4 mounted on the rear wheel connecting rod assembly 7, and a seat folding rod assembly 6 hinged at both ends to the seat assembly 5 and the folding assembly 8 respectively.

[0040] When folding, first unlock the frame fixing assembly 9 to allow the sliding member 81 to return to a free sliding state along the main rod axis; push the sliding member 81 to move along the main rod axis, gradually moving it away from the fixing member 82; since the rear wheel connecting rod assembly 7 is hinged to one end of the sliding member 81 and the fixing member 82 respectively, when the sliding member 81 moves away from the fixing member 82, the rear wheel connecting rod assembly 7 simultaneously drives the rear wheel assembly 4 to fold; at the same time, the two ends of the seat folding rod assembly 6 are respectively hinged to the other ends of the seat cushion 51 and the sliding member 81 and the fixing member 82, and the backrest 52 is linked to the seat folding rod assembly 6 through the backrest folding member 63 and hinged to the seat cushion 51. When the sliding member 81 moves, it simultaneously drives the seat cushion 51 and the backrest 52 to fold; finally, fold the steering assembly 2 and the foot pedal assembly 13 to complete the overall folding and storage of the mobility scooter.

[0041] Figures 1 to 4This is a schematic diagram of an embodiment of the manual folding method provided in this application. The mobility scooter includes a chassis 1, a steering assembly 2, a front wheel 3, a rear wheel assembly 4, a seat assembly 5, a seat folding rod assembly 6, a rear wheel connecting rod assembly 7, a folding assembly 8, and a frame fixing assembly 9. The chassis 1 includes a main rod 11 and a vertical rod 12 fixedly connected to each other. The vertical rod 12 is equipped with a foot pedal assembly 13. The steering assembly 2 includes a steering vertical rod 21, a handle 22, and a latch 23. The steering vertical rod 21 is assembled inside the vertical rod 12 and... The front wheel 3 is connected via the upright 12. The folding assembly 8 is mounted on the main rod 11 and includes a slider 81, a sliding kit 811 embedded in the slider 81, and a fixing member 82. The slider 81 and the embedded sliding kit 811 are integrally formed and can slide freely along the axial direction of the main rod 11. The fixing member 82 is fixedly installed at the lower end of the main rod 11. The rear wheel connecting rod assembly 7 consists of two pairs of oppositely arranged connecting rod assemblies, including a side control rod 71, a linkage rod 72, and a folding rod connector 73. One end of the side control rod 71 is connected to the slider. The other end of the hinge 81 is hinged to the linkage rod 72 via the folding rod connector 73, and the other end of the linkage rod 72 is hinged to the fixing member 82. The rear wheel assembly 4 has two wheels, which are respectively connected to two sets of connecting rods consisting of the side control rod 71, the linkage rod 72, and the folding rod connector 73. The seat assembly 5 includes a seat cushion 51 and a backrest 52 hinged to the seat cushion 51. The seat folding rod assembly 6 consists of two sets of folding rods that are hinged to each other, including a front control rod 61, a rear control rod 621, and a rod hinged to the rear control rod 621. One end of the rotating rod 622 and the backrest folding piece 63; the front control rod 61 forms one group, and the rear control rod 621, the rotating rod 622 hinged to one end of it, and the backrest folding piece 63 form another group; the two groups of folding rods are hinged to each other, and one end is respectively hinged to the sliding piece 81 and the fixing piece 82, and the other end is hinged to the seat cushion 51. The other end of the backrest folding piece 63 is hinged to the backrest 52; the seat cushion 51 and the backrest 52 and the seat folding rod group 6 form a linkage relationship with the folding assembly 8 through multiple sets of hinge structures.

[0042] The frame fixing assembly 9 includes a button 91 and a beaded spring clip 92. The main rod 11 of the chassis 1 has at least one corresponding functional hole for assembly with the frame fixing assembly 9. The button 91 is fixedly installed on the outside of the main rod 11, and the beaded spring clip 92 is fixedly installed inside the main rod 11. The button 91 is engaged with the functional hole of the main rod 11. By pressing the button 91, the downward action is transmitted to the beaded spring clip 92, which can control the radial retraction and ejection of the beaded spring clip 92. Under the combined action of the button 91, the beaded spring clip 92 and the slider 81, the slider 81 can be unlocked or locked, thereby controlling the folding and unfolding of the frame.

[0043] Optionally, this application also includes another embodiment using an electric telescopic rod to control the unfolding and folding of the mobility scooter. The frame fixing assembly 9 is removed and replaced with an electric telescopic rod 10, with a sliding groove 111 provided on the lower side of the main rod 11. The electric telescopic rod 10 is fixedly installed inside the main rod 11, and its telescopic end is fixedly connected to a sliding member 81 through the sliding groove 111. Controlling the extension and retraction of the electric telescopic rod 10 can drive the sliding member 81 to move axially along the sliding groove 111, thereby synchronously controlling the unfolding and folding of the frame.

[0044] It should be noted that electric telescopic rods have the advantages of convenient operation, high control precision, and stable power output. This application prefers electric telescopic rod 10 as the driving component. Other driving devices that can achieve linear drive and drive the sliding member 81 to move controllably along the axis of the main rod 11 (such as electric push rods) are all equivalent alternatives to this application and should be included in the protection scope of this application.

[0045] Optionally, this application also supports another embodiment where only the rear wheel assembly and seat cushion are folded. By eliminating the backrest 52 in the seat assembly 5 and the backrest folding member 63 in the seat folding rod assembly 6, the mobility scooter can be folded by only the rear wheel assembly 4 and seat cushion 51. This method reduces the number of parts in the mobility scooter and decreases its size and weight.

[0046] Figure 1 and Figure 2 The device is shown in its deployed and usable state. Figure 3 This describes the state of the device during the folding process. Figure 4 This is the final folded state of the device. For example... Figures 3 to 4 As shown, when the device needs to be folded, the frame fixing assembly 9 is unlocked, allowing the sliding member 81 to return to its active state. The sliding member 81 moves away from the fixing member 82 along the axis of the main rod 11. The coordinated folding action of the mobility scooter is triggered by multiple sets of hinge structures: when the sliding member 81 slides, it drives the side control rod 71 to move synchronously. The folding rod connector 73 pulls the linkage rod 72, thereby driving the rear wheel assembly 4 to fold inward synchronously. At the same time, the front control rod 61 of the seat folding rod assembly 6 moves synchronously with the sliding member 81, thereby driving the rear control rod 621, the rotating rod 622 and the backrest folding member 63 to fold in linkage, thereby pulling down and folding the seat cushion 51 and the backrest 52 synchronously.

[0047] Furthermore, unlock the latch 23 of the steering component 2, fold the steering column 21 downwards, and simultaneously fold and store the foot pedal component 13, completing the overall folding and storage of the mobility scooter.

[0048] Please refer to the schematic diagram of the two functional hole positions corresponding to the frame fixing assembly provided in this application. Figure 5 and Figure 6 ,in Figure 5 This is a partial structural diagram of the frame fixing assembly of this application.Figure 6 This is a cross-sectional view of the frame fixing assembly of this application. The specific working principle of this embodiment is as follows:

[0049] The frame mounting assembly 9 includes a button 91 and a double-ball spring clip 92. The main rod 11 has two functional holes corresponding to the button mounting hole and the spring clip mounting hole, for mounting the button 91 and the spring clip 92. The button 91 is fixedly mounted on the corresponding functional hole on the main rod 11, and the spring clip 92 is fixedly embedded inside the main rod 11. The double-ball spring clips are located within the two functional holes. The button 91 and the spring clip 92 share a common functional hole and are axially aligned to form a linkage. The spring clip 92 has two balls; pressing either ball will cause the other ball to move synchronously. The button 91 has a pressure point opposite to one of the balls in the spring clip 92, allowing the retraction and ejection of the balls to be controlled by pressing the button 91.

[0050] The sliding assembly 811 is embedded and fixed inside the sliding member 81, forming an integrated structure. The sliding member 81 and the sliding assembly 811 are provided with ball positioning holes corresponding to each other along the axial direction, and the lower end of the sliding assembly 811 is provided with an inclined guide groove, which is adapted to the axial direction of the ball of the ball-bearing snap 92. When the sliding member 81 and the sliding assembly 811 move along the main rod 11 towards the frame fixing assembly 9, the inclined guide groove of the sliding assembly 811 first contacts the ball, and with the sliding action, the ball is pressed radially downward along the inclined surface of the guide groove, so that the sliding member 81 and the sliding assembly 811 can smoothly pass the ball; when the ball positioning hole moves to be aligned with the axial direction of the ball, the ball is ejected radially under the elastic reset action and is locked into the ball positioning hole, realizing the locking and fixing of the sliding member 81 and keeping the frame in the unfolded state.

[0051] When unlocking, pressing down on button 91 transmits a downward pressing action, causing its bottom pressure point to simultaneously press down on the ball bearing buckle 92, thereby causing the ball to retract radially and move out of the ball bearing positioning hole; at this time, the slider 81 and the slider kit 811 are unlocked, restoring the free sliding state along the axis of the main rod 11, allowing the frame to be folded.

[0052] Please refer to the schematic diagram of the functional hole structure corresponding to the frame fixing assembly provided in this application. Figure 7 and Figure 8 ,in Figure 7 This is a partial structural diagram of the frame fixing assembly of this application. Figure 8This is a cross-sectional view of the frame fixing assembly of this application. The specific working principle of this embodiment is consistent with the working principle of the above-described two functional holes. The functional hole for the main rod 11 to cooperate with the frame fixing assembly 9 is changed to one. At this time, a single-bead spring clip 92 is selected, and the button 91 is changed from a direct press type to a lever type. The pressing action is transmitted through the lever. The pressing end of the lever type button has a pressure point, and the width of the pressure point is smaller than the ball of the spring clip 92. When it is necessary to unlock the slider 81, the pressing action of the spring clip 92 is transmitted through the lever 91, pressing the ball of the spring clip 92 into the main rod 11. Since the pressure point of the button 91 is smaller than the ball of the spring clip 92, the slider 81 tends to move with the weight of the frame itself, so that the fixing hole of the slider 81 and the sliding kit 811 is misaligned with the functional hole of the main rod 11. The ball of the spring clip 92 cannot pop out, the button 91 can be smoothly reset, and the slider 81 returns to the free sliding state.

[0053] This application also provides a schematic diagram of the principle structure for electric unfolding and folding, please refer to it. Figure 9 and Figure 10 ,in Figure 9 This is a partial schematic diagram of the electrically unfolding and folding structure of this application. Figure 10 This is a schematic internal cross-sectional view of the electrically operated unfolding and folding structure of this application. The main rod 11 of the chassis 1 eliminates the mounting holes corresponding to the chassis fixing assembly 9, and the unfolding and folding of the chassis is no longer controlled by the chassis fixing assembly 9. Instead, an electrically operated telescopic rod is used to complete the unfolding and folding of the chassis. The specific working principle of this embodiment is as follows:

[0054] The electric telescopic rod 10 is embedded and fixedly installed in the main rod 11 of the vehicle chassis 1. The lower end of the main rod 11 is provided with a sliding groove 111. The sliding element 81 and the sliding kit 811 are integrally assembled on the main rod 11 and have axially corresponding connection holes. The telescopic end of the electric telescopic rod 10 is fixedly connected to the sliding element 81 and the sliding kit 811 through the sliding groove 111. In this embodiment, a fixing screw 812 is used for connection. Specifically, the fixing screw 812 is passed through the sliding element 81, the sliding kit 811, the sliding groove 111, and the telescopic rod in sequence and then fixed, so that the telescopic end of the electric telescopic rod 10 forms a rigid connection with the sliding element 81. When the electric telescopic rod 10 is energized and extends, its telescopic end pushes the sliding member 81 along the sliding groove 111 of the main rod 11 in a direction away from the fixed member 82 via the fixing screw 812, thereby driving the rear wheel connecting rod assembly 7 and the seat folding rod assembly 6 to perform a folding action. When the electric telescopic rod 10 is energized and retracts, its telescopic end pulls the sliding member 81 along the sliding groove 111 of the main rod 11 in a direction closer to the fixed member 82, thereby driving the rear wheel connecting rod assembly 7 and the seat folding rod assembly 6 to perform an unfolding action. By controlling the movement of the sliding member 81 along the main rod 11 through the telescopic movement of the electric telescopic rod 10, the folding and unfolding process of the mobility scooter is automated, simplifying the operation steps and improving ease of use.

[0055] It should also be noted that this embodiment uses a fixing screw 812 as the fixing fastener, which has the characteristics of stable connection and convenient assembly and disassembly, and can effectively ensure the transmission reliability between the electric telescopic rod and the sliding part. In practical applications, rivets, pins or other types of rigid connecting parts can also be selected according to specific needs, as long as the synchronous movement of the telescopic end of the electric telescopic rod and the sliding part can be achieved. These equivalent substitution methods should all fall within the protection scope of this application.

[0056] This application also provides another embodiment that folds only the rear wheel assembly and seat; please refer to [reference needed]. Figure 11 This embodiment eliminates the backrest folding component 63, and the backrest 52 is either eliminated or only hinged to the seat cushion 51; this embodiment takes the elimination of the backrest 52 and the backrest folding component 63 as an example, while other structures (vehicle chassis 1, steering assembly 2, front wheel 3, rear wheel assembly 4, rear wheel connecting rod assembly 7, folding assembly 8, etc.) are the same as in the core embodiment ( Figures 1-4(This is to maintain consistency.) When folding, the frame fixing assembly 9 is unlocked, and the sliding member 81 moves away from the fixing member 82 along the axis of the main rod 11. At this time, the rear wheel connecting rod assembly 7, driven by the sliding member 81, folds the rear wheel assembly 4 inward through the coordinated action of the side control rod 71, the linkage rod 72, and the folding rod connector 73. Simultaneously, the front control rod 61 of the seat folding rod assembly 6 moves with the sliding member 81, driving the rear control rod 621 and the rotating rod 622 to pull down and fold the seat cushion 51. Since the backrest 52 and the backrest folding member 63 are eliminated, only the seat cushion 51 participates in the folding of the seat part, which simplifies the overall structure, reduces the number of parts, reduces the overall weight of the commuter vehicle, and makes the folded volume smaller, further improving the convenience of folding operation and the overall lightweight level of the vehicle, especially suitable for usage scenarios with higher requirements for weight and operation steps.

[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way. The scope of protection of this application should be determined by the scope of the claims. Although this application has disclosed the preferred embodiment above, it is not intended to limit this application. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this application. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application without departing from the content of the technical solution of this application shall fall within the scope of the technical solution of this application.
