Description

Technical Field

[0001] The present invention relates to a folding scooter, belonging to the technical field of scooters. Background Art

[0002] Scooters are means of transportation and auxiliary tools for the purpose of getting around. They are quite widely used in modern society. Existing scooters are small in size and low in power, safe and convenient to use, and have low usage requirements. In order to facilitate storage and reduce space, current scooters usually have a certain folding function.

[0003] In a Chinese patent application with the publication number CN116767407A, a folding scooter is disclosed, which includes a frame unit, a driving unit, and a steering unit; the frame unit includes a front frame, a rear frame, a support frame, and a locking mechanism. The two sides of the rear end of the front frame are hinged to the first hinge points provided on the two inner sides of the front end of the rear frame. The support frame is located above the front frame; the locking mechanism includes an unfolding lock guard plate and a folding lock guard plate that are rotatably provided on the inner side of the rear end of the support frame and arranged side by side in the front and rear directions.

[0004] The design of the folding mechanism of the folding electric scooter is too complex and too troublesome to operate, causing certain inconvenience to users. Moreover, the seat folding part mostly adopts a parallelogram link mechanism or a cross-shaped folding mechanism. Therefore, two support rods are required on each side of the seat to cooperate to complete the folding, which not only increases the production cost but also increases the weight of the vehicle. Summary of the Invention

[0005] The purpose of the present invention is to provide a folding scooter, which solves the problems existing in the prior art, such as overly complex design, overly troublesome operation resulting in inconvenient use, and increased vehicle weight leading to increased energy consumption.

[0006] The above technical object of the present invention is mainly solved by the following technical solutions: A folding scooter, including a front frame. On both sides of the front frame, there are connecting parts that are mirror - set with each other and bend upward and backward above the rear side of the front frame. The top of the connecting part is connected with a support rod that can be flipped forward relative to the front frame. Above the front frame and corresponding to the space between the two support rods, there is a seat board rotatably connected to the support rods. Inside the support rod, there is a transmission rod. One end of the transmission rod is rotatably connected to the connecting part, and the other end of the transmission rod is rotatably connected to the seat board and can be folded as the seat board flips upward. In the middle of the front side of the front frame, there is a vertically - arranged handlebar rod that is circumferentially rotatably connected to the front frame. The handlebar rod is rotatably connected to the front frame and can be locked. When the support rod and the handlebar rod are folded, the seat board and the support rod are located below the handlebar rod; the above - mentioned support rod can drive the seat to flip forward relative to the connecting part of the front frame to realize the folding of the whole seat. At the same time, the transmission rod rotates synchronously with the flipping of the seat board, and the support rod rotates synchronously with the transmission rod, so that the support rod, the transmission rod and the seat board rotate synchronously and approach the front frame to realize folding. The handlebar rod can then be folded and located above the seat board and the support rod to realize the overall folding of the scooter. At the same time, the handlebar rod folded above the seat board and the support rod can prevent the internal wires and circuit boards of the handlebar rod from being squeezed and causing circuit damage. The structure of the above - mentioned scooter is simple, easy to operate, reduces the self - weight of the scooter body, effectively improves the portability of the scooter, reduces energy consumption, makes the handling of the scooter more convenient, increases the endurance of the scooter, and reduces the production cost.

[0007] Preferably, at the bottom of one side of the seat board connected to the support rod, there are two mirror - set movable pins that can reciprocally move towards the two side support rods respectively. On the support rod, there is a first positioning hole for the movable pin to insert. On one side of the support rod close to the side of the seat board, there is a second positioning hole. The positions of the first positioning hole and the second positioning hole are both on the rotation trajectory of the seat board; the above - mentioned movable pin can cooperate with the first positioning hole to position the seat board, so that the seat board cannot flip upward. When the seat board cannot flip upward, the transmission rod and the support rod cannot rotate either. Thus, through the positioning of the movable pin, the limit of the seat board and the support rod is realized, so that the support rod maintains the supporting effect on the seat board. At the same time, when the movable pin leaves the first positioning hole, the seat board can flip upward. The setting of the above - mentioned second positioning hole enables the movable pin to be stuck into the second positioning hole when the seat board flips upward for folding, positions the seat board, restricts the flipping of the seat board, keeps the seat board stable when the seat is folded, avoids swinging, and can limit the folding state of the transmission rod and the support rod, preventing the transmission rod and the support rod from easily disengaging from the folded state.

[0008] Preferably, one end of the transmission rod connected to the seat plate is rotatably connected to the seat plate through a connecting piece. The connecting piece is provided with an extending portion bent towards the seat plate. The inner side of the extending portion is provided with a convex column extending towards the seat plate, and the seat plate is provided with a groove matching the convex column. The arrangement of the connecting piece and the extending portion on the transmission rod increases the barrier between the seat plate and the support rod when the seat plate is in a horizontal state for the user to sit on, protects the seat and the support rod, and reduces wear. The matching arrangement of the convex column and the groove strengthens the stability between the seat plate and the support rod and prevents the seat plate from shaking.

[0009] Preferably, an arc-shaped guide groove is provided inside the support rod. The center of the arc-shaped guide groove coincides with the rotation center of the seat plate. The connecting piece is located inside the arc-shaped guide groove and can move along the arc track of the arc-shaped guide groove. The arrangement of the arc-shaped guide groove can guide and limit the movement of the connecting piece when the seat plate rotates, so that the seat plate and the support rod can rotate stably through the transmission of the transmission rod, ensuring the smoothness and stability when the seat plate and the support rod are folded.

[0010] Preferably, positioning portions for allowing the movable pins to pass through are provided on both sides of the bottom of the seat plate. Guide grooves are provided inside the positioning portions along the axial direction of the movable pins. Convex portions in contact with the inner walls of the guide grooves are provided at the outer ends of the movable pins. Telescopic springs are provided corresponding to the circumferences of the movable pins in the guide grooves. The arrangement of the positioning portions and the guide grooves facilitates guiding and limiting the axial movement of the movable pins, ensuring the stability of the axial movement of the movable pins and preventing the movable pins from being radially offset under force. The arrangement of the convex portions and the telescopic springs enables the movable pins to automatically protrude outwards under the action of the telescopic springs and be connected by the convex portions entering the first positioning hole or the second positioning hole.

[0011] Preferably, a push plate movable along the front-back direction of the seat plate is provided between the two positioning portions. Driving blocks for driving the axial movement of the movable pins are provided on both sides of the push plate. A limiting cover connected to the seat plate is covered on the driving blocks. A limiting groove for allowing the driving blocks to move is provided between the limiting cover and the seat plate. The arrangement of the push plate facilitates driving the push plate to move when folding is required. The push plate can drive the movable pins to leave the first positioning hole or the second positioning hole, so as to facilitate folding or canceling the folded state of the seat. The arrangement of the limiting cover and the limiting groove can protect the components on the driving blocks and limit the moving distance and direction of the push plate through the limiting groove, ensuring the stability of the push plate during movement.

[0012] Preferably, a convex block is provided on the outer side of the driving block, and a return spring is provided on the convex block and arranged along the moving direction of the push plate. The end of the return spring is connected to a protrusion provided at the bottom of the seat plate. The setting of the above convex block facilitates the cooperation with the protrusion to fix the return spring, so that the push plate can automatically reset after moving, facilitating subsequent operations, realizing the continuity of the push plate movement, and thus realizing the repeatability of the seat folding function.

[0013] Preferably, an inclined groove inclined towards the inner end of the movable pin is provided on the end face of the driving block. A roller is provided at the inner end of the movable pin and extends into the inclined groove and abuts against the side wall of the inclined groove. A limiting portion that abuts against the side wall of the movable pin is provided inside the limiting cover. The setting of the above inclined groove enables the movement of the push plate to drive the roller at the inner end of the movable pin to move along the inclined groove through the inclined groove of the driving block, thereby driving the outer ends of the two movable pins to move axially synchronously under the limitation of the limiting portion and the positioning portion, ensuring the stability of the movable pin during movement and realizing the synchronous control of the flipping of both sides of the seat plate.

[0014] Preferably, a bottom column extending upwards is provided in the middle of the front side of the front frame. A base is provided at the bottom of the handlebar rod and is circumferentially rotatably connected to the bottom column. An air rod capable of controlling the rotation of the handlebar rod relative to the base towards the rear side of the front frame is provided inside the handlebar rod. A switch extending into the handlebar rod and contacting the movable end at the top of the air rod and capable of rotating up and down is provided in the middle of the handlebar rod. The fixed end at the bottom of the air rod is rotatably connected to the middle of the base. The above handlebar rod can axially rotate relative to the bottom column through the base to facilitate the steering function of the scooter. The setting of the air rod can control the rotational folding of the handlebar rod through the switch, making the rotational folding of the handlebar rod easier and more labor-saving, and locking the state of the handlebar rod through the switch.

[0015] Preferably, the switch includes a driving portion contacting the valve at the top of the air rod and a pressing portion located outside the handlebar rod and arranged towards the rear side of the front frame. A positioning member is provided on the circumferential side of the top of the air rod. The top of the positioning member extends to the side of the driving portion and is provided with a limiting column located above the driving portion. The above driving portion can be turned up and down through the pressing portion to facilitate controlling the telescopic movement of the air rod by contacting the valve of the air rod, thereby assisting the handlebar rod to automatically fold or return to the upright state, making the folding of the handlebar rod more convenient and labor-saving. The positioning member fixes the radial position of the air rod to prevent the air rod from shaking. The limiting column can limit the flipping angle of the pressing portion, thereby limiting the elongation range of the air rod to ensure that the air rod can automatically stop elongating after the handlebar rod is folded.

[0016] Therefore, the present invention has the characteristics of simple structure, convenient operation, reducing the self-weight of the scooter body, effectively improving the portability of the scooter, reducing energy consumption, making the handling of the scooter more convenient, increasing the endurance of the scooter, and reducing production costs.

[0024] The technical solution of the present invention will be further specifically described below through embodiments in conjunction with the accompanying drawings.

[0025] As Figure 1-2 shown, a folding scooter includes a front frame 1. On both sides of the front frame 1, there are connecting parts 11 that are mirror - set with each other and bend upward and backward above the rear side of the front frame 1. The top of the connecting part 11 is connected with a support rod 2 that can be flipped forward relative to the front frame 1. Above the front frame 1 and corresponding to the space between the two support rods 2, there is a seat plate 3 that is rotatably connected with the support rods 2. Inside the support rod 2, there is a transmission rod 22. One end of the transmission rod 22 is rotatably connected with the connecting part 11, and the other end of the transmission rod 22 is rotatably connected with the seat plate 3 and can be folded as the seat plate 3 flips upward. In the middle of the front side of the front frame 1, there is a vertically - arranged faucet rod 4 that is circumferentially rotatably connected with the front frame 1, and the faucet rod 4 is rotatably connected with the front frame 1 and can be locked. When the support rod 2 and the faucet rod 4 are folded, the seat plate 3 and the support rod 2 are located below the faucet rod 4.

[0026] The above-mentioned front frame, support rod and seat board are all made of carbon fiber material, which not only ensures hardness but also makes the vehicle body lighter. The connecting part of the front frame extends to the rear side of the vehicle body and bends upward to connect the support rod. The support rod extends upward until it connects to the seat back. The seat board is connected to the middle section of the support rod and cooperates with the seat back to facilitate the user to sit. The seat board is arranged in the direction of the front frame on the front side of the vehicle body. During normal use, the seat board is in a horizontal state relative to the front frame, and the support rod and the transmission rod are both in an upright state. When folding is required, the seat board is turned up, and then it can be turned and folded forward towards the front frame together with the transmission rod and the support rod. Subsequently, the locking of the handlebar rod is released, and the handlebar rod is folded above the support rod and the seat board, thus completing the folding of the mobility scooter.

[0027] As Figure 3-4 shown, one end of the transmission rod 22 connected to the seat board 3 is rotatably connected to the seat board 3 through a connecting piece 221. The connecting piece 221 is provided with an extension part 222 bent towards the seat board 3. The inner side of the extension part 222 is provided with a convex column 223 extending towards the seat board 3. The seat board 3 is provided with a groove 32 matching the convex column 223. The inner side of the support rod 2 is provided with an arc-shaped guide groove 23. The center of the arc of the arc-shaped guide groove 23 is consistent with the rotation center of the seat board 3. The connecting piece 221 is located in the arc-shaped guide groove 23 and can move along the arc track of the arc-shaped guide groove 23. Two mirror-image movable pins 31 that can reciprocally move towards both sides of the support rod 2 are provided at the bottom of one side of the seat board 3 connected to the support rod 2. The support rod 2 is provided with a first positioning hole 21 for the movable pin 31 to be inserted. A second positioning hole 24 is provided on one side of the support rod 2 close to the side of the seat board 3. The positions of the first positioning hole 21 and the second positioning hole 24 are both located on the rotation track of the seat board 3.

[0028] When the above-mentioned seat board is in a horizontal state, the side of the seat board abuts against the protrusion on the side wall of the support rod, so that the seat board is kept in a horizontal state, and the movable pin is located in the first positioning hole. A connecting piece is arranged between the protrusion of the seat board and the support rod. The extension part of the connecting piece is located between the protrusion of the support rod and the side of the seat board, reducing the wear caused by direct contact between the seat and the support rod. Both the connecting piece and the extension part are made of plastic. The connecting piece is fixed on the transmission rod, and the side of the seat board, the connecting piece and the transmission rod are always rotatably connected. When the side of the seat board is connected to the connecting piece, the convex column of the extension part is always stuck in the groove. When the seat board is turned up, the movable pins on both sides of the seat board leave the first positioning hole. During the rotation of the seat board, the side of the seat board drives the end of the transmission rod to move in the arc-shaped guide groove through the connecting piece until it moves to the other end of the arc-shaped guide groove, and the movable pin is stuck in the second positioning hole, and the support rod and the transmission rod are completed to be turned and folded, and the seat board is turned up to complete the folding.

[0029] As Figure 5-6As shown in the figure, positioning parts 33 for allowing the movable pins 31 to pass through are provided on both sides of the bottom of the seat plate 3. A guiding groove 331 is provided in the positioning part 33 along the axial direction of the movable pin 31. A convex part 311 that abuts against the inner wall of the guiding groove 331 is provided at the outer end of the movable pin 31. A telescopic spring 332 is provided in the guiding groove 331 corresponding to the circumferential side of the movable pin 31. A push plate 34 that can move in the front-back direction of the seat plate 3 is provided between the two positioning parts 33. Driving blocks 35 for driving the axial movement of the movable pins 31 are provided on both sides of the push plate 34. A limiting cover 36 connected to the seat plate 3 is covered on the driving block 35. A limiting groove 361 for allowing the driving block 35 to move is provided between the limiting cover 36 and the seat plate 3. A convex block 351 is provided on the outer side of the driving block 35. A reset spring 352 is provided on the convex block 351 along the moving direction of the push plate 34. The end of the reset spring 352 is connected to a protrusion 37 provided at the bottom of the seat plate 3. An inclined groove 353 that inclines towards the inner end of the movable pin 31 is provided on the end face of the driving block 35. A roller 312 that extends into the inclined groove 353 and abuts against the side wall of the inclined groove 353 is provided at the inner end of the movable pin 31. A limiting part 362 that abuts against the side wall of the movable pin 31 is provided inside the limiting cover 36.

[0030] The above-mentioned movable pin passes through the positioning part and extends into the limiting cover. The convex part at the outer end of the movable pin can extend into the first positioning hole or the second positioning hole. The inner end of the movable pin is located inside the limiting part of the limiting cover and is connected with the roller located inside the inclined groove, and the roller abuts against the side wall of the inclined groove; when the outer end of the movable pin is located inside the first positioning hole or the second positioning hole, the inner end of the movable pin is located at the opening of the inclined groove, and the telescopic spring acts to push the convex part of the movable pin so that the outer end of the movable pin is located inside the first positioning hole or the second positioning hole, and the reset spring is in a relaxed state.

[0031] When it is necessary to control the movable pin to leave the first positioning hole or the second positioning hole, pull the push plate. The push plate moves along the limiting groove on the limiting cover, and drives the driving block to move synchronously, and the reset spring starts to contract continuously. When the driving block moves, it drives the roller at the inner end of the movable pin to move through the inclined groove, so that the inner section of the movable pin moves along the inclined groove, and the movable pin moves axially towards the push plate under the limiting action of the guiding groove and the limiting part. At this time, the telescopic spring contracts, and the convex part at the outer end of the movable pin moves into the guiding groove, and the movable pin thus leaves the first positioning hole or the second positioning hole. After adjusting the seat state, release the push plate. The push plate returns to its original position under the action of the reset spring. At the same time, the convex part of the movable pin moves out of the guiding groove along the inclined groove under the action of the telescopic spring until it enters the first positioning hole and the second positioning hole.

[0032] As Figure 7As shown in the figure, a bottom column 12 extending upward is provided in the middle of the front side of the front frame 1. A base 41 that is circumferentially rotatably connected to the bottom column 12 is provided at the bottom of the handlebar rod 4. An air rod 42 that can control the handlebar rod 4 to rotate toward the rear side of the front frame 1 relative to the base 41 is provided inside the handlebar rod 4. A switch 43 that extends into the handlebar rod 4 and contacts the movable end at the top of the air rod 42 and can rotate up and down is provided in the middle of the handlebar rod 4. The fixed end at the bottom of the air rod 42 is rotatably connected to the middle of the base 41. The switch 43 includes a driving portion 431 that contacts the valve at the top of the air rod 42 and a pressing portion 432 that is located outside the handlebar rod 4 and is arranged toward the rear side of the front frame 1. A positioning member 44 is provided on the circumferential side at the top of the air rod 42. The top of the positioning member 44 extends to the side of the driving portion 431 and is provided with a limiting post 441 located above the driving portion 431.

[0033] The top end of the above-mentioned handlebar rod is connected to the display screen of the scooter. The steering control of the scooter can be realized by the circumferential rotation of the handlebar rod on the bottom column. The above-mentioned air rod is a product already available on the market and is prior art, so it will not be elaborated here. When the handlebar rod is in the vertical state, the pressing portion buckles on the side of the handlebar rod facing the seat board, and the driving portion contacts the valve of the air rod without squeezing. At this time, neither the air rod nor the handlebar rod inside the handlebar rod can rotate and fold on the base; press the switch, so that the pressing portion deflects toward the handlebar rod, and the driving portion synchronously deflects toward the valve of the air rod and forms a squeeze, so that the air rod starts to extend. Since the length of the handlebar rod is fixed, the extension of the air rod will drive the handlebar rod to synchronously deflect toward the seat board, so that the folding of the handlebar rod can be easily realized, and the speed of the handlebar rod during deflection can be controlled to avoid damage to electrical control components such as circuits and circuit boards caused by the handlebar rod falling due to too fast rotation.
