Description

Technical Field

[0001] The present invention relates to a folding mechanism for a folding vehicle and a folding vehicle comprising the same. Background Technology

[0002] Folding vehicles (such as folding motorcycles, folding electric bikes, and folding bicycles) have advantages such as reducing storage space and being easy to carry, and are now widely used.

[0003] The core component of a folding bicycle is its foldable frame. Existing foldable frames are basically folded horizontally, using flanges and locking devices to connect and separate the main beams of the frame, reducing the space occupied by the bicycle. However, this type of frame reduces the overall strength of the bicycle, and the folded bicycle cannot be moved by the wheels, making it difficult to transport and causing great inconvenience to the user. Summary of the Invention

[0004] The purpose of this invention is to provide a folding mechanism for a folding vehicle and a folding vehicle comprising the same.

[0005] According to one aspect of the present invention, a folding mechanism for a folding vehicle is provided, comprising a base, a rotating member, a support rod A, a support rod B, a base, and a fixing member.

[0006] One end of the rotating component is hinged to the base, and the rotating component is provided with a boss.

[0007] One end of support rod A is hinged to the other end of the rotating component, and the other end of support rod A is hinged to the base.

[0008] One end of support rod B is hinged to the base, and the other end of support rod B is hinged to the base plate.

[0009] The fastener passes through the boss and secures the boss to the base; the fastener and the base are detachably connected.

[0010] The base has hinge slots at both ends for mounting the rear wheel bracket of the folding bicycle.

[0011] When the folding mechanism of this invention is used on a folding vehicle, the rear wheel bracket of the folding vehicle is hinged to the hinge groove of the base. One end of the rear wheel shock absorber on the rear wheel bracket is fixed to the middle position of the rotating component. The base is installed on the vehicle body of the folding vehicle, and the seat is installed in the seat component of the folding vehicle. When the vehicle body needs to be folded, the fixing component is removed from the base. Since the rotating component is rotatably connected to the base, support rod A is rotatably connected to the rotating component, support rod B is rotatably connected to the base, and both support rod A and support rod B are rotatably connected to the seat, when the rear wheel bracket of the folding vehicle is longitudinally flipped, the rear wheel bracket can flip around the base. At the same time, the rear wheel shock absorber on the rear wheel bracket will pull the rotating component downward to make the rotating component flip around the base. When the rotating component flips, it pushes the seat component of the folding vehicle towards the front wheel. The seat component will drive support rod A and support rod B to rotate around the rotating component and the base respectively. Finally, the seat component of the folding vehicle can be pushed onto the vehicle body of the folding vehicle. At this point, the rear wheel bracket also flips to the designated position, thus completing the folding and storage of the folding bike. The folding mechanism of this invention has a simple structure, and the folded bike occupies less space after folding. Moreover, the folding method is longitudinal folding, which does not affect the overall strength of the folding bike, ensuring the stability and safety of the folding bike. Furthermore, the folded bike can still move normally in the front and rear directions using the front and rear wheels, making it very easy to transport and thus bringing great convenience to the user. When it is necessary to flip and open the folding bike, pull up the seat component of the folding bike and push it backward. The seat component drives the support rod A and support rod B to rotate. Support rod A drives the rotating component to rotate towards the base. The rotating component drives the rear wheel bracket to rotate around the base through the rear wheel shock absorber on the rear wheel bracket. When the boss on the rotating component abuts against the base, the rear wheel bracket also flips and opens to the designated position. Then, the boss is fixed to the base using the fixing component. At this point, the folding bike is flipped and opened.

[0012] In some embodiments, the other end of the rotating component may be provided with two opposing lugs, and one end of the support rod A is accommodated between the two lugs and hinged to the lugs. Thus, since the hinged part of the support rod A is located between the two lugs on the rotating component, the folded support rod A can be accommodated between the two lugs and attached to the rotating component, further reducing the overall space occupied after folding.

[0013] In some implementations, the support rod A can be arc-shaped. This arc-shaped support rod A ensures that it does not interfere with rotating parts during folding and rotation, allowing the seat of the fully folded folding vehicle to adhere to the vehicle body, further reducing the overall space occupied after folding.

[0014] In some embodiments, a mounting shaft may also be included. One end of the rotating member may be provided with a hinge joint, and the side of the base may be provided with a hinge portion. The hinge joint is housed in the hinge portion, and the mounting shaft passes through the hinge portion and the hinge joint. Thus, when the rotating member rotates on the base via the hinge joint and the hinge portion on the side of the base, the boss on the rotating member can abut or separate from the base. When folding is required, the boss separates from the base. After the folding mechanism is fully opened, the boss abuts against the base.

[0015] In some embodiments, the top of the base may be provided with a through groove, and one end of the support rod B is accommodated in the through groove and hinged to the base. Thus, the hinged connection achieved by accommodating one end of the support rod B in the through groove can improve the overall strength of the folding mechanism.

[0016] In some embodiments, there can be two support rods B and two through slots, with one end of each support rod B housed in one of the two through slots and hinged to the base. Thus, the two support rods B ensure that the supporting force on the seat component of the folding vehicle remains balanced, guaranteeing the stability of the seat component.

[0017] In some embodiments, support rod B may include interconnected horizontal and vertical sections arranged in an L-shape. The horizontal section is housed in a through slot and hinged to the base, while one end of the vertical section is hinged to the base. Thus, because the horizontal and vertical sections are arranged in an L-shape, the horizontal section housed in the through slot ensures that the vertical section, when fully folded, can adhere to the body of the folding vehicle, further reducing the overall space occupied after folding. Furthermore, when the folding mechanism is fully opened, the horizontal section can press against the through slot, ensuring the stability of the seat component of the folding vehicle.

[0018] In some embodiments, the boss may have a through hole, and the top of the base may have a receiving hole. One end of the fastener passes through the through hole on the boss and is received in the receiving hole. Thus, when the vehicle body needs to be folded, the fastener can be directly removed from the receiving hole of the base. At this time, the rotating component can rotate around the base. When the folding mechanism is fully opened, the boss on the rotating component abuts against the base. At this time, the fastener can be passed through the through hole on the boss and received in the receiving hole to complete the fixation of the rotating component to the base.

[0019] In some embodiments, a mounting groove for mounting the rear wheel shock absorber of a folding bicycle can be provided at the center of the rotating component, and mounting holes can be provided on the two side walls of the mounting groove. Thus, when the folding mechanism is installed on the folding bicycle, one end of the rear wheel shock absorber is placed in the mounting groove on the rotating component, and then a fixed shaft is passed through the mounting hole in the mounting groove and the end of the rear wheel shock absorber to fix the rear wheel shock absorber of the folding bicycle to the rotating component. The assembly and disassembly of the rear wheel shock absorber of the folding bicycle from the folding mechanism is very convenient.

[0020] According to another aspect of the invention, a folding vehicle is also provided, including the aforementioned folding mechanism, wherein the free end of the rear wheel support of the folding vehicle is accommodated in a hinge groove and hinged to a base, one end of the rear wheel shock absorber of the folding vehicle is disposed on a rotating member, the base is disposed on the body of the folding vehicle, and the base is disposed at the inner bottom of the seat component of the folding vehicle.

[0021] The folding vehicle of the present invention reduces the space occupied after folding, and the folding method is longitudinal folding, which does not affect the overall strength of the folding vehicle, ensuring the stability and safety of the folding vehicle. Moreover, the folded vehicle body can still be moved normally in the front and rear directions by means of the front and rear wheels, making it very easy to transport, thus bringing great convenience to the user.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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. Therefore, they should not be construed as limitations on this invention.

[0032] Figure 1 and Figure 2 The diagram schematically illustrates the structure of a folding mechanism for a folding vehicle according to one embodiment of the present invention.

[0033] refer to Figure 1 and Figure 2 A folding mechanism for a folding bicycle includes a base 1, a rotating component 2, a support rod A3, a support rod B4, a base 5, and a fixing component 6. Furthermore, the folding mechanism for the folding bicycle may also include a mounting shaft 7.

[0034] refer to Figure 2 The base 1 has a hinge portion 12 formed on its side, and a groove (not shown) is formed on the hinge portion 12. The lower right part of the rotating member 2 has a hinge joint 23 formed. The hinge joint 23 is accommodated in the groove on the hinge portion 12 and can rotate in the groove. The mounting shaft 7 passes through one end of the hinge portion 12 and the hinge joint 23 in the groove and exits from the other end of the hinge portion 12, thereby mounting the hinge joint 23 together with the hinge portion 12. The hinge joint 23 can rotate on the base 1 with the mounting shaft 7 as the rotation axis. A limit bolt can be installed on the end of the mounting shaft 7 that exits from the other end of the hinge portion 12 to prevent the mounting shaft 7 from coming off.

[0035] refer to Figure 2 The base 1 has a receiving hole 14 formed on its top, and the rotating part 2 has a protruding boss 21 formed on its right side, with a through hole 24 formed on the boss 21; (Reference) Figure 1 When the folding mechanism is not folded, the boss 21 on the rotating part 2 abuts against the top of the base 1, and the through hole 24 on the boss 21 is aligned with the receiving hole 14 on the top of the base 1; Reference Figure 2The lower end of the fixing member 6 passes through the through hole 24 on the boss 21 and is accommodated in the receiving hole 14. The fixing member 6 can also be removed from the receiving hole 14. When the fixing member 6 is accommodated in the receiving hole 14, the rotating member 2 cannot rotate on the base 1. When the fixing member 6 is removed from the receiving hole 14, the rotating member 2 can rotate on the base 1. When the rotating member 2 rotates on the base 1, the boss 21 on the rotating member 2 can abut or separate from the base 1. When folding is required, the boss 21 separates from the base 1. After the folding mechanism is fully opened, the boss 21 abuts against the base 1. When the vehicle body needs to be folded, the fixing member 6 is removed from the receiving hole 14 of the base 1. At this time, the rotating member 2 can rotate around the base 1. When the folding mechanism is fully opened ( Figure 1 (As shown in the figure), the boss 21 on the rotating part 2 abuts against the base 1. At this time, the fixing part 6 is passed through the through hole 24 on the boss 21 and accommodated in the accommodating hole 14 to complete the fixing of the rotating part 2 and the base 1.

[0036] refer to Figure 1 and Figure 2 In this embodiment, the fastener 6 can be a pin structure, which can be installed and removed by inserting and pulling. In other embodiments, the fastener 6 can also be a bolt structure, with the through hole 24 being a through hole and the receiving hole 14 being a threaded countersunk hole, which can be installed and removed by turning the fastener 6.

[0037] refer to Figure 1 and Figure 2 The upper left part of the rotating part 2 has two oppositely arranged lugs 22. The right end of the support rod A3 is accommodated between the two lugs 22. The right end of the support rod A3 is installed between the two lugs 22 through a pivot. The support rod A3 can rotate around the pivot, thereby realizing the rotational connection between the support rod A3 and the rotating part 2. Since the right end of the support rod A3 is located between the two lugs 22 on the rotating part 2, the folded support rod A3 can be accommodated between the two lugs 22 and attached to the rotating part 2, thereby reducing the space occupied after folding.

[0038] refer to Figure 2 The support rod A3 is arc-shaped. The arc-shaped support rod A3 can ensure that the non-hinged part of the support rod A3 will not interfere with the rotating part 2 during the rotation and folding process. When the folding mechanism is installed on the folding car, the seat part of the folding car after being fully folded can be attached to the body of the folding car, reducing the overall space occupied after folding.

[0039] refer to Figure 2 The left end of the support rod A3 is hinged to the base 5. The left end of the support rod A3 can be installed at the bottom of the base 5 through a pivot. The support rod A3 and the base 5 can rotate relative to each other.

[0040] refer to Figure 2 The top of the base 1 is formed with a through groove 13. The lower end of the support rod B4 is accommodated in the through groove 13 and hinged to the base 1. The lower end of the support rod B4 can be mounted in the through groove 13 on the base 1 through a pivot.

[0041] refer to Figure 2 The support rod B4 includes a horizontal bar portion 41 and a vertical bar portion 42, which are integrally formed and connected, and are arranged in an L-shape. The horizontal bar portion 41 is housed in a through groove 13 and connected to the two side walls of the through groove 13 via a pivot. The horizontal bar portion 41 can rotate around the pivot, thereby achieving a rotatable connection between the support rod B4 and the base 1. The upper end of the vertical bar portion 42 is hinged to the base 5, and the upper end of the vertical bar portion 42 can be mounted on the bottom of the base 5 via a pivot. The vertical bar portion 42 and the base 5 can rotate relative to each other. When the folding mechanism is installed on the folding vehicle, since the horizontal bar portion 41 and the vertical bar portion 42 are arranged in an L-shape, and the horizontal bar portion 41 is housed in the through groove 13, it can ensure that the vertical bar portion 42, after being fully rotated and folded, can be attached to the body of the folding vehicle, reducing the overall space occupied after folding. Moreover, when the folding mechanism is fully opened, that is, when the support rod B4 is fully flipped open ( Figure 1 (As shown in the diagram), the crossbar 41 can press against the through groove 13, which can improve the overall strength of the folding mechanism and ensure the stability of the seat component of the folding vehicle, thus ensuring the load-bearing capacity of the seat component of the folding vehicle.

[0042] refer to Figure 2 In this embodiment, there are two support rods B4 and two through slots 13 on the base 1. The crossbar portions 41 of the two support rods B4 are respectively accommodated in the two through slots 13. The two through slots 13 are located on both sides of the receiving hole 14 on the base 1. The two support rods B4 can ensure that the supporting force on the seat component of the folding bicycle remains balanced, ensuring the stability of the seat component and the load-bearing capacity of the seat component of the folding bicycle. In other embodiments, the number of support rods B4 can also be adjusted appropriately according to the load-bearing requirements, and the number of support rods B4 is the same as the number of through slots 13.

[0043] refer to Figure 2 The base 1 has concave hinge grooves 11 formed at both ends, which are used to install the rear wheel bracket of the folding car.

[0044] refer to Figure 2The rotating part 2 has a recessed mounting groove (not shown) formed in the middle. The mounting groove is located below the two lugs 22. The mounting groove is used to install the rear wheel shock absorber of the folding car. The two side walls of the mounting groove have mounting holes 25. When the folding mechanism is installed on the folding car, one end of the rear wheel shock absorber of the folding car is accommodated in the mounting groove on the rotating part 2. Then, the rear wheel shock absorber of the folding car can be fixed on the rotating part 2 by passing a fixed shaft through the mounting hole 25 on the mounting groove and the end of the rear wheel shock absorber.

[0045] Figure 3 The diagram schematically illustrates the structure of a folding vehicle according to one embodiment of the present invention.

[0046] refer to Figure 3 The folding vehicle includes the aforementioned folding mechanism, rear wheel bracket 101, rear wheel shock absorber 102, vehicle body 103, and seat component 104.

[0047] refer to Figure 3 The two free ends of the rear wheel bracket 101 are respectively housed in the hinge slots 11 on both sides of the base 1. The mounting shaft 7 in the folding mechanism passes through one free end of the rear wheel bracket 101, one end of the hinge part 12, the hinge joint 23, the other end of the hinge part 12, and the other free end of the rear wheel bracket 101 in sequence, thereby installing the rear wheel bracket 101, the base 1, and the rotating part 2 together. The rear wheel bracket 101 can rotate around the mounting shaft 7, thereby realizing the hinge between the rear wheel bracket 101 and the base 1.

[0048] refer to Figure 3 One end of the rear wheel shock absorber 102 is fixed on the rear wheel bracket 101, and the other end of the rear wheel shock absorber 102 is accommodated in the mounting groove on the rotating member 2. Then, a fixed shaft is passed through the mounting hole 25 on the mounting groove and the end of the rear wheel shock absorber 102 to fix the rear wheel shock absorber 102 on the rotating member 2.

[0049] refer to Figure 3 The base 1 of the folding mechanism is fixed on the vehicle body 103, and the base 5 of the folding mechanism is installed and fixed on the inner bottom of the seat component 104.

[0050] Figures 4 to 8 schematically shown Figure 3 The image shows the state changes of the folding vehicle during the folding process.

[0051] refer to Figure 4 and Figure 5When the folding bike needs to be folded, remove the fixing piece 6 from the through hole 24 on the boss 21 and the receiving hole 14 on the base 1. Since the rotating part 2 is rotatably connected to the base 1, the support rod A3 is rotatably connected to the rotating part 2, the support rod B4 is rotatably connected to the base 1, and both the support rod A3 and the support rod B4 are rotatably connected to the base 5, when the rear wheel bracket 101 is flipped longitudinally (along... Figure 4 (As shown in the F1 direction), the rear wheel bracket 101 can rotate around the base 1, and at the same time, the rear wheel shock absorber 102 on the rear wheel bracket 101 will pull down the rotating component 2, causing the rotating component 2 to rotate around the base 1. Figure 6 As shown in the diagram, when the rotating component 2 flips, it pushes the seat component 104 of the folding bike towards the front wheel. The seat component 104, through the base 5, drives the support rod A3 to rotate around the rotating component 2 and the two support rods B4 to rotate around the base 1. Figure 7 (As shown in the diagram), the seat component 104 of the folding bike can finally be pushed onto the frame 101 of the folding bike. At this time, the rear wheel bracket 101 also flips to the designated position, thus completing the folding and storage of the folding bike. Figure 8 As shown in the diagram, the folding mechanism of this invention has a simple structure, reduces the space occupied by the folded cart, and the folding method is longitudinal, which does not affect the overall strength of the folding cart, ensuring the stability and safety of the folding cart. Moreover, the folded cart can still move normally in the front and rear directions using the front and rear wheels, making it very easy to carry, thus bringing great convenience to the user; when it is necessary to flip and open the folding cart, pull up the seat part 104 of the folding cart and push it backward (along the direction shown in the diagram). Figure 8 (As shown in direction F2), the seat component 104 drives the support rods A3 and B4 to rotate. The support rod A3 drives the rotating component 2 to rotate towards the base 1. The rotating component 2 drives the rear wheel bracket 101 to rotate around the base 1 via the rear wheel shock absorber 102 on the rear wheel bracket 101. When the boss 21 on the rotating component 2 abuts against the base 1, the rear wheel bracket 101 also flips open to the designated position. Figure 4 (as shown in the image), and then use the fastener 6 to fix the boss 21 to the base 1. At this time, the folding car is fully opened. When opening the folding car, you can also manually turn the rear wheel bracket 101 for assistance.

[0052] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
