[0001] The present invention relates to the technical field of scooters, in particular to a scooter that can be folded horizontally. Background Art

[0002] Nowadays, for people with limited mobility and the elderly, mobility scooters have become a must-have for them to go out. However, common mobility scooters need to be unfolded when in use, which is time-consuming and laborious to operate. As a result, automatically foldable mobility scooters have appeared on the market. Users only need to press a button to control the automatic unfolding and folding of the mobility scooter, and do not need to spend time and effort to unfold and fold the mobility scooter.

[0003] Refer to the utility model patent application No. 202220077862.4, entitled Folding Frame, which includes a front frame, a rear frame and a front wheel bracket, wherein the front end of the front frame is pivotally connected to the front wheel bracket, the rear end of the front frame is pivotally connected to the front end of the rear frame, and further includes a folding seat bracket, a linkage rod and a pull rod, wherein the folding seat bracket is arranged on the rear frame, the front end of the pull rod is pivotally connected to the front wheel bracket, the rear end of the pull rod is pivotally connected to the rear frame, the front end of the linkage rod is pivotally connected to the pull rod, and the linkage rod is The rear end is connected to the folding seat bracket, so that when the front frame is folded towards the rear frame, the folding seat bracket is driven to move towards the rear frame and fold. At the same time, the pull rod can drive the front wheel bracket to adjust its relative position with the front frame, so that the folding frame of this utility model is convenient and quick to fold, has a simple structure, and has a small volume after folding. However, this folding frame is in a vertical state as a whole after folding, rather than a horizontal state. When carrying it, the user needs to tilt it to a certain extent by hand in order to pick it up and move it, which is not convenient to use. Summary of the invention

[0004] In order to solve the above problems, the present invention proposes a transversely foldable scooter, which solves the problem that traditional scooters cannot be folded transversely and are not convenient to use.

[0005] The technical solution adopted by the present invention is: a transversely foldable scooter, including a front frame assembly, a vehicle body main frame and a seat assembly, the front frame assembly and the vehicle body main frame are rotatably connected, the vehicle body main frame is rotatably connected with a rotating seat, the rotating seat is rotatably connected with a connecting rod, and also includes a first support rod and a second support rod, the first support rod and the second support rod are cross-pivoted, the upper end of the first support rod and / or the upper end of the second support rod are rotatably connected to the seat assembly, the lower end of the first support rod is rotatably connected to the vehicle body main frame, and the lower end of the second support rod is rotatably connected to the connecting rod; in the process of the rotating seat flipping forward, the first support rod flips forward, and the second support rod is pulled forward as a whole by the connecting rod and finally falls over laterally.

[0006] Through the above technical solution, when the user folds the mobility scooter, the user drives the rotating seat to flip forward on the main frame of the vehicle body. The rotating rotating seat drives the connecting rod to move forward. The second support rod enables the seat assembly to move forward as a whole through the pulling action of the connecting rod. The first support rod flips forward simultaneously, so that the seat assembly can be folded above the main frame of the vehicle body; the seat assembly can be folded horizontally under the pulling action of the connecting rod, so that the mobility scooter can be in a horizontal state as a whole after folding. The user does not need to perform actions such as tilting, but only needs to grab the mobility scooter with his hands to move and carry it, which is more convenient to use.

[0007] Furthermore, the vehicle body main frame includes a cross bar and an extension rod connected to each other, the rotating seat and the cross bar are rotatably connected, the lower end of the first support rod is rotatably connected to the extension rod, and the rotation center of the rotating seat on the cross bar is closer to the front frame assembly than the rotation center of the first support rod on the extension rod.

[0008] Through the above technical solution, the rotating seat is driven to flip on the cross bar, and the connecting rod moves forward with the flipping of the rotating seat. The rotation center of the rotating seat on the cross bar is closer to the front frame assembly than the rotation center of the first support rod on the extension rod, which effectively ensures that the first support rod flips forward when the connecting rod moves forward. The seat assembly can move forward as a whole under the pulling action of the connecting rod, and the second support rod can fall sideways on the main frame of the vehicle body to avoid the seat assembly being not folded into place and causing the overall volume to be too large.

[0009] Furthermore, the front frame assembly includes a connecting seat and a direction control rod that are connected to each other, the connecting seat and the cross bar are rotatably connected, and a transmission rod is commonly connected between the connecting seat and the rotating seat, and the rotation center of the transmission rod on the connecting seat is higher than the rotation center of the connecting seat on the cross bar, and the transmission rod can pull the front frame assembly to fold during the forward flipping of the rotating seat.

[0010] Through the above technical solution, when the rotating seat flips on the cross bar, the driving transmission rod moves backward, so that the transmission rod can pull the connecting seat, and the rotation center of the transmission rod on the connecting seat is higher than the rotation center of the connecting seat on the cross bar. When the connecting seat is pulled by the transmission rod, the connecting seat flips backward on the cross bar and drives the direction control rod to flip backward as well, so that the front frame assembly can be horizontally folded above the main frame of the vehicle body and reduce the space occupied by the storage of the mobility scooter.

[0011] Furthermore, a limiting column is provided on the transmission rod, and an arc-shaped limiting hole for the limiting column to extend into is provided on the rotating seat, and a first end and a second end are provided in the arc-shaped limiting hole. During the process of the rotating seat flipping forward, the limiting column rotates from the first end to the second end, and when the limiting column contacts the second end, the front frame assembly is flipped backward by the pulling of the transmission rod and finally folded above the seat assembly.

[0012] Through the above technical solution, when the rotating seat flips forward, the limit post on the transmission rod rotates from the first end to the second end. At this time, the relative position between the transmission rod and the connecting seat remains unchanged until the limit post contacts the second end. The rotating seat starts to drive the transmission rod to move, and the transmission rod can pull the connecting seat, so that when the connecting rod pulls the seat assembly forward, the position of the front frame assembly can remain unchanged before the limit post contacts the second end, avoiding the seat assembly and the front frame assembly from being folded horizontally at the same time and interfering with each other, so that the seat assembly can be smoothly folded horizontally above the main frame of the vehicle body.

[0013] Furthermore, extension plates are respectively arranged on both sides of the connection seat, a positioning shaft is commonly connected between the two extension plates, and the transmission rod is rotatably connected to the positioning shaft.

[0014] Through the above technical solution, the transmission rod is rotatably connected to the positioning shaft, and the two ends of the positioning shaft are respectively connected to the two extension plates, so that when the transmission rod rotates on the positioning shaft, the two extension plates can share the force acting on the positioning shaft, and the force on both sides of the connecting seat is more even, preventing the connecting seat from tilting during rotation.

[0015] Furthermore, a linear drive device is connected to the main frame of the vehicle body, a transmission shaft is connected to the rotating seat, an eccentric block is arranged on the transmission shaft, the movable end of the linear drive device is rotatably connected to the eccentric block, the movable end of the linear drive device moves laterally and drives the rotating seat to flip around the cross bar through the transmission shaft.

[0016] Through the above technical solution, the movable end of the linear drive device installed on the main frame of the vehicle body can move laterally, and drive the transmission shaft to move by rotating the connected eccentric block, so that the transmission shaft transmits the driving force to the rotating seat, and the rotating seat can be flipped on the cross bar. The user only needs to start the linear drive device to unfold or fold the scooter, which is very convenient to use.

[0017] Furthermore, a self-locking device for limiting the flipping of the rotating seat is arranged between the rotating seat and the main frame of the vehicle body, and the self-locking device includes a locking plate and a spring, and the locking plate is rotatably connected to the rotating seat, a first mounting column is arranged on the rotating seat, and a second mounting column is arranged on the extension rod, the lower end of the locking plate can be clamped with the second mounting column, one end of the spring is connected to the locking plate, and the other end of the spring is connected to the first mounting column; a support plate is also arranged on the rotating seat, and a mounting block is correspondingly arranged on the extension rod, and when the front frame assembly and the seat assembly are fully unfolded, the support plate rests against the mounting block.

[0018] Through the above technical solution, after the front frame assembly and the seat assembly are fully unfolded on the main frame of the vehicle body, the relative positions of the rotating seat and the connecting rod are fixed by utilizing the clamping action of the lower end of the locking plate and the second mounting column, and the mutual cooperation between the support plate and the mounting block enables the extension rod to provide certain support to the rotating seat, thereby preventing the front frame assembly and the seat assembly from shaking or shifting when used by the user, making the overall structure more stable and making the mobility scooter more convenient to use.

[0019] Furthermore, the seat assembly includes a seat, a mounting member and a backrest, the mounting member is connected to the backrest, the seat is rotatably connected to the mounting member, the upper end of the first support rod is rotatably connected to the mounting member, and the upper end of the second support rod is rotatably connected to the seat.

[0020] Through the above technical solution, the backrest is connected to the mounting part and the seat and the mounting part are rotatably connected so that when the mobility scooter is folded horizontally, the backrest can be tilted as the mounting part rotates, thereby greatly reducing the overall volume of the seat assembly, taking up less space when storing the mobility scooter, and facilitating the movement and carrying of the user.

When the user folds the scooter, the user drives the rotating seat 4 to flip forward on the main frame 2 of the vehicle body. The rotating rotating seat 4 drives the connecting rod 5 to move forward. The second support rod 7 makes the seat assembly 3 move forward as a whole through the pulling action of the connecting rod 5. The first support rod 6 flips forward synchronously, so that the seat assembly 3 can be folded above the main frame 2 of the vehicle body; the seat assembly 3 can be folded horizontally under the pulling action of the connecting rod 5, so that the scooter can be in a horizontal state as a whole after folding. The user does not need to perform actions such as tilting, but only needs to grab the scooter with his hands to move and carry it, which is more convenient to use.

[0038] See also Figure 1 , 2As shown in Figures 3 and 5, the vehicle body main frame 2 includes a cross bar 201 and an extension bar 202 connected to each other, the rotating seat 4 is rotationally connected to the cross bar 201, the lower end of the first support bar 6 is rotationally connected to the extension bar 202, and the rotation center of the rotating seat 4 on the cross bar 201 is closer to the front frame assembly 1 than the rotation center of the first support bar 6 on the extension bar 202. The rotating seat 4 is driven to flip on the cross bar 201, and the connecting rod 5 moves forward with the flipping of the rotating seat 4, and the rotation center of the rotating seat 4 on the cross bar 201 is closer to the front frame assembly 1 than the rotation center of the first support bar 6 on the extension bar 202, which effectively ensures that the first support bar 6 is also flipped forward when the connecting rod 5 moves forward, and the seat assembly 3 can move forward as a whole under the pulling action of the connecting rod 5, and the second support bar 7 can be horizontally lodged on the vehicle body main frame 2 to avoid the seat assembly 3 not being folded properly and causing the overall volume to be too large.

[0039] Preferably, the extension rod 202 is disposed at the bottom of the cross bar 201 .

[0040] See also Figure 1 , 2 As shown in Figures 3 and 7, the front frame assembly 1 includes a connecting seat 101 and a direction control rod 102 that are interconnected. The connecting seat 101 and the cross bar 201 are rotatably connected. A transmission rod 10 is commonly connected between the connecting seat 101 and the rotating seat 4. The rotation center of the transmission rod 10 on the connecting seat 101 is higher than the rotation center of the connecting seat 101 on the cross bar 201. The transmission rod 10 can pull the front frame assembly 1 to fold during the forward flipping process of the rotating seat 4. When the rotating seat 4 flips over on the cross bar 201, the driving transmission rod 10 moves backward, so that the transmission rod 10 can pull the connecting seat 101, and the rotation center of the transmission rod 10 on the connecting seat 101 is higher than the rotation center of the connecting seat 101 on the cross bar 201. When the connecting seat 101 is pulled by the transmission rod 10, the connecting seat 101 flips backward on the cross bar 201 and drives the direction control rod 102 to flip backward as well, so that the front frame assembly 1 can be horizontally folded above the vehicle body main frame 2 and reduce the space occupied by the storage of the scooter.

[0041] Front wheels 21 are respectively installed on both sides of the connecting seat 101 . There are two connecting rods 5 on the vehicle body main frame 2 , and rear wheels 22 are installed on both connecting rods 5 .

[0042] Preferably, the connecting seat 101 is arc-shaped as a whole, so that it can withstand a larger load.

During the process of the rotating seat 4 flipping forward, the limiting column 11 rotates from the first end 121 to the second end 122. When the limiting column 11 contacts the second end 122, the front frame assembly 1 is flipped backward by the pulling of the transmission rod 10 and finally folded above the seat assembly 3. When the rotating seat 4 flips forward, the limiting post 11 on the transmission rod 10 rotates from the first end 121 to the second end 122. At this time, the relative position between the transmission rod 10 and the connecting seat 101 remains unchanged until the limiting post 11 contacts the second end 122. The rotating seat 4 starts to drive the transmission rod 10 to move. The transmission rod 10 can pull the connecting seat 101, so that when the connecting rod 5 pulls the seat assembly 3 forward, the position of the front frame assembly 1 can remain unchanged before the limiting post 11 contacts the second end 122, avoiding the seat assembly 3 and the front frame assembly 1 from being folded laterally at the same time and interfering with each other, so that the seat assembly 3 can be folded laterally above the vehicle body main frame 2 very smoothly.

[0044] The center of the arc-shaped limiting hole 12 coincides with the rotation center of the rotating seat 4 on the crossbar 201 , so that the relative position between the transmission rod 10 and the connecting seat 101 remains unchanged during the process of the limiting column 11 rotating from the first end 121 to the second end 122 .

[0045] After the limiting column 11 contacts the second end 122, the rotation center of the transmission rod 10 in the arc limiting hole 12 and the rotation center of the first support rod 6 on the extension rod 202 are respectively located on both sides of the rotation center of the rotating seat 4 on the cross bar 201, and the force directions of the transmission rod 10 and the first support rod 6 are inconsistent, so that the transmission rod 10 can pull the front frame assembly 1 backward during the forward flipping of the rotating seat 4.

[0046] See also Figure 1 , 2 As shown in FIGS. 3 and 7 , an extension plate 13 is provided on both sides of the connection seat 101, a positioning shaft 14 is commonly connected between the two extension plates 13, and the transmission rod 10 is rotatably connected to the positioning shaft 14. The transmission rod 10 is rotatably connected to the positioning shaft 14, and both ends of the positioning shaft 14 are respectively connected to the two extension plates 13, so that when the transmission rod 10 rotates on the positioning shaft 14, the two extension plates 13 can share the force applied to the positioning shaft 14, and the force applied on both sides of the connection seat 101 is more uniform, preventing the connection seat 101 from tilting when rotating.

[0047] Preferably, the two extension plates 13 are respectively disposed at two ends of the connection base 101 and are symmetrical to each other.

The movable end of the linear drive device 15 installed on the vehicle body main frame 2 can move laterally, and drives the transmission shaft 16 to move through the eccentric block 17 connected by rotation, so that the transmission shaft 16 transmits the driving force to the rotating seat 4, and the rotating seat 4 can flip on the cross bar 201. The user only needs to start the linear drive device 15 to unfold or fold the scooter, which is very convenient to use.

[0050] Preferably, the linear drive device 15 is an electric push rod.

[0051] See also Figure 1 , 2 As shown in Figures 9, a self-locking device 18 for limiting the turning over of the rotating seat 4 is arranged between the rotating seat 4 and the main frame 2 of the vehicle body. The self-locking device 18 includes a locking piece 181 and a spring 182. The locking piece 181 is rotatably connected to the rotating seat 4. A first mounting column 19 is arranged on the rotating seat 4, and a second mounting column 20 is arranged on the extension rod 202. The lower end of the locking piece 181 can be engaged with the second mounting column 20, one end of the spring 182 is connected to the locking piece 181, and the other end of the spring 182 is connected to the first mounting column 19; a support plate 8 is also arranged on the rotating seat 4, and a mounting block 9 is correspondingly arranged on the extension rod 202. When the front frame assembly 1 and the seat assembly 3 are fully unfolded, the support plate 8 rests on the mounting block 9. After the front frame assembly 1 and the seat assembly 3 are fully unfolded on the vehicle body main frame 2, the relative positions of the rotating seat 4 and the connecting rod 5 are fixed by utilizing the clamping action of the lower end of the locking plate 181 and the second mounting column 20, and the mutual cooperation between the support plate 8 and the mounting block 9 enables the extension rod 202 to provide certain support for the rotating seat 4, thereby preventing the front frame assembly 1 and the seat assembly 3 from shaking or shifting when used by the user, making the overall structure more stable and making the scooter more convenient to use.

[0052] See also Figure 1 , 2As shown in Figures 3, 4 and 8, the seat assembly 3 includes a seat 301, a mounting member 302 and a backrest 303, the mounting member 302 and the backrest 303 are connected, the seat 301 and the mounting member 302 are rotatably connected, the upper end of the first support rod 6 is rotatably connected to the mounting member 302, and the upper end of the second support rod 7 is rotatably connected to the seat 301. The backrest 303 is connected to the mounting member 302 and the seat 301 and the mounting member 302 are rotatably connected, so that when the scooter is folded horizontally, the backrest 303 can be tilted as the mounting member 302 rotates, thereby greatly reducing the overall volume of the seat assembly 3, taking up less space when the scooter is stored, and facilitating the movement and transportation of the user.

[0053] When the present invention is in use, the user starts the linear drive device 15, so that the movable end of the linear drive device 15 moves laterally, and the eccentric block 17 connected by rotation drives the transmission shaft 16 to move, so that the transmission shaft 16 transmits the driving force to the rotating seat 4, and the rotating seat 4 flips on the cross bar 201. The rotating rotating seat 4 drives the connecting rod 5 to move forward, and the second support rod 7 pulls the connecting rod 5 to make the seat assembly 3 move forward as a whole. The first support rod 6 flips forward synchronously and drives the mounting member 302 to rotate, and the backrest 303 can be tilted with the rotation of the mounting member 302, so that the seat 301 and the backrest 303 can be tilted and folded laterally. The front frame 10 is stacked on the main frame 2 of the vehicle body. At the same time, when the rotating seat 4 flips forward, the limiting column 11 on the transmission rod 10 rotates from the first end 121 to the second end 122. At this time, the relative position between the transmission rod 10 and the connecting seat 101 remains unchanged until the limiting column 11 contacts the second end 122. The rotating seat 4 starts to drive the transmission rod 10 to move. The transmission rod 10 can pull the connecting seat 101, so that the front frame assembly 1 is flipped backward by the pulling of the transmission rod 10 and finally folded horizontally above the seat assembly 3. The folded scooter is in a horizontal state. The user only needs to grab the scooter with his hands to move it, which is more convenient for the user to move and carry.
