Description

Technical Field

[0001] The present invention relates to a folding vehicle, and more particularly to a folding vehicle that can be disassembled after folding to facilitate carrying and storage. Background Art

[0002] Existing four-wheel electric vehicles are generally foldable, and there are various folding forms. For example, the seat bracket folds towards the frame, the front frame telescopically folds relative to the rear frame, the front frame rotates and folds towards the rear frame, etc. The ultimate goal is to reduce the volume of the folding vehicle for convenient carrying and storage. However, as the functions of four-wheel electric vehicles become more and more, the structure becomes more and more complex, and the volume and weight also become larger and larger. Even when folded in the above ways, the volume and weight are still very large, and carrying and storage become more and more difficult. Summary of the Invention

[0003] The object of the present invention is to provide a folding vehicle that can be disassembled after folding to facilitate carrying and storage.

[0004] To achieve the above object, the disassemblable folding vehicle provided by the present invention includes a front frame, a rear frame and a disassembling mechanism. The disassembling mechanism is connected between the front frame and the rear frame. When combined, the disassembling mechanism can rotatably connect the front frame and the rear frame. When disassembled, the disassembling mechanism can separate the front frame and the rear frame from each other.

[0005] Compared with the prior art, since the present invention connects a disassembling mechanism between the front frame and the rear frame, and the disassembling mechanism can be combined or disassembled by itself. Therefore, when combined, the front frame and the rear frame can rotate to achieve the purpose of mutual folding or unfolding; when disassembled, the front frame and the rear frame can be separated to achieve the purpose of disassembling the folding vehicle into two parts, the front and the rear, which greatly facilitates carrying and storage and improves the convenience of use.

[0006] Preferably, the front frame has a front rod and a pull rod, the rear frame has a rear rod, and the front rod, the pull rod and the rear rod are respectively pivotally connected to the disassembling mechanism.

[0007] Specifically, the disassembling mechanism includes a locking member, a connecting member, and a clamping member. The clamping member is fixed to the rear rod; the connecting member is pivotally connected to the front rod to form a first pivot axis; the pull rod has a rotating shaft, and the rotating shaft is rotatably connected to the connecting member, and the rotating shaft is rotatable and detachably clamped to the clamping member; the locking member is pivotally connected to the front rod, and the pivot center axis is coaxial with the first pivot axis; the locking member has a locking portion, and the locking portion is detachably clamped to the clamping member. By pivotally connecting the connecting member to the front rod through the first pivot axis, rotatably connecting the rotating shaft of the pull rod to the connecting member and clamping it to the clamping member, and pivotally connecting the locking member to the first pivot axis and clamping it to the clamping member at the same time, the connecting member can be relatively fixedly connected to the rear rod, and the front rod and the pull rod can respectively form a pivoting relationship with the rear rod. Therefore, the front frame can be rotatable relative to the rear frame, achieving the purpose of being able to approach and fold each other. When folding, only need to detach the locking portion of the locking member from the clamping member, thereby unlocking the pull rod, so that the rotating shaft can be disengaged from the clamping member, and at the same time the connecting member can be disengaged from the rear rod. Therefore, the front frame, the locking member, and the connecting member can be completely disengaged from the rear rod, achieving the purpose of disassembling the folding bicycle, which greatly facilitates carrying and storage and improves the convenience of use.

[0008] Specifically, the clamping member has a first clamping opening and a second clamping opening. The rotating shaft is clamped in the first clamping opening, and the locking portion is clamped in the second clamping opening.

[0009] Specifically, when the front frame is unfolded relative to the rear frame, the rear end portion of the front rod abuts against the front end portion of the rear rod.

[0010] Specifically, the opening direction of the first clamping opening intersects with the opening direction of the second clamping opening. Since the rotating shaft can only slide out in the opening direction of the first clamping opening when it is clamped in the first clamping opening, and the locking member can only slide out in the opening direction of the second clamping opening, by intersecting the second clamping opening with the first clamping opening, the locking member and the pull rod can limit each other, and then form an integral body with the connecting member and the clamping member, so that the pull rod and the rear rod are pivotally connected to each other.

[0011] Specifically, the opening direction of the first clamping opening faces forward, and the opening direction of the second clamping opening faces downward.

[0012] Specifically, the disassembling mechanism further includes an elastic member, and the elastic member provides an elastic force for the locking portion of the locking member to enter the second clamping opening. By providing the elastic member, it can prevent the locking portion of the locking member from accidentally disengaging from the second clamping opening, avoid accidental separation of the front frame and the rear frame, and improve the safety of use.

[0013] Specifically, the locking member is provided with a connecting portion, the pull rod is provided with a pin, and both ends of the elastic member are respectively connected to the connecting portion and the pin.

[0014] Specifically, when the front frame is unfolded relative to the rear frame, the pull rod is located below the locking member to block the rotation of the locking member; when the front frame is folded relative to the rear frame, the pull rod is located at one end of the locking member to release the locking member. This can enable the locking member to be unlocked only when the folding bike is folded, that is, the folding bike can only be disassembled when folded, thereby improving the safety of use.

[0015] Specifically, a positioning rib is provided on one side of the connecting member, and a positioning groove is provided at the front end of the front rod. When the front frame is unfolded relative to the rear frame, the positioning rib is engaged in the positioning groove. Through the cooperation of the positioning rib and the positioning groove, the front rod and the rear rod can be quickly positioned when unfolded, improving the convenience of operation.

[0016] Specifically, the connecting member has a transverse portion and a vertical portion fixedly connected to the transverse portion. The transverse portion is located below the front end of the rear rod, the vertical portion is located on the front end face of the rear rod, and the positioning rib is provided on the side surface of the vertical portion.

[0017] Preferably, a pivot seat is provided on the lower side of the rear end of the front rod, and the connecting member is pivotally connected to the pivot seat. By providing the pivot seat, the connection between the front rod and the rear rod can be made more convenient and the structure can be more compact.

[0018] Preferably, the disassemblable folding bike further includes a first driving mechanism, and the first driving mechanism is arranged on the front frame and drives the front rod and the rear rod to fold. By providing the first driving mechanism, the front frame and the rear frame can be conveniently folded or unfolded, improving the convenience of unfolding and folding.

[0019] Specifically, the first driving mechanism includes a first electric push rod, a first swing rod and a second swing rod. One end of the first swing rod is pivotally connected to the front rod, one end of the second swing rod is pivotally connected to the connecting member, the other end of the first swing rod is pivotally connected to the other end of the second swing rod, and the first electric push rod is pivotally connected to the front frame and the output end is connected to the first swing rod. By using the first electric push rod for automatic folding and unfolding, it greatly facilitates the operation of the user and improves the convenience of use.

[0020] Preferably, the disassemblable folding bike further includes a foldable seat folding bracket, and the seat folding bracket is arranged on the rear frame.

[0021] Specifically, the separable folding bicycle further includes a second driving mechanism, which is disposed on the rear frame and drives the seat folding bracket to fold. By providing the second driving mechanism, the seat folding bracket can be conveniently folded or unfolded, improving the convenience of unfolding and folding.

[0022] Specifically, the seat folding bracket includes a first rod, a second rod, a first driving rod, a seat post and a linkage rod. The first rod and the second rod are cross - arranged and pivotally connected to each other in the middle; the upper end of the first rod is pivotally connected to the front end of the seat post, and the lower end is pivotally connected to the rear end of the rear frame; the upper end of the second rod is pivotally connected to the lower end of the linkage rod, the lower end of the second rod is pivotally connected to the upper end of the first driving rod, and the lower end of the first driving rod is pivotally connected to the front end of the rear frame; the upper end of the linkage rod is pivotally connected to the rear end of the seat post, and the output end of the second driving mechanism is connected to the first driving rod to drive the first driving rod to swing.

[0037] To describe in detail the technical content, structural features, and achieved effects of the present invention, the following will be described in detail in conjunction with the embodiments and with reference to the accompanying drawings.

[0038] Such as Figures 1 to 6As shown in the figure, the detachable folding bicycle 100 of the present invention includes a front frame 1, a rear frame 2 and a disassembly mechanism 3. The disassembly mechanism 3 is connected between the front frame 1 and the rear frame 2 and is symmetrically arranged on both inner sides of the detachable folding bicycle 100. When assembled, the disassembly mechanism 3 can rotatably connect the front frame 1 and the rear frame 2, and when disassembled, the disassembly mechanism 3 can separate the front frame 1 and the rear frame 2 from each other. Specifically, the front frame 1 has a front rod 11, a pull rod 12 and a front wheel bracket 13. The front rod 11 and the pull rod 12 are symmetrically arranged on both sides of the front frame 1. The front end of the front rod 11 is pivotally connected to the front wheel bracket 13, and the front end of the pull rod 12 is pivotally connected to the front wheel bracket 13. The rear frame 2 has a rear rod 21 and a rear wheel bracket 22. The rear rod 21 is symmetrically arranged on both sides of the rear frame 2. The rear end of the rear rod 21 is pivotally connected to the rear wheel bracket 22. The rear end of the front rod 11, the rear end of the pull rod 12 and the front end of the rear rod 21 are respectively pivotally connected to the disassembly mechanism 3. More specifically, the disassembly mechanism 3 includes a locking member 31, a connecting member 32 and a engaging member 33. The locking members 31 of the disassembly mechanism 3 on both sides of the detachable folding bicycle 100 are connected by a cross bar so that the two operate synchronously. The engaging member 33 is fixed to the inner side of the front end of the rear rod 21, and the engaging member 33 has a first bayonet 331 and a second bayonet 332. One end of the connecting member 32 is pivotally connected to the front rod 11. Specifically, a pivot seat 111 is provided on the lower side of the rear end of the front rod 11, and the connecting member 32 is pivotally connected to the pivot seat 111 to form a first pivot axis 112. By providing the pivot seat 111, the connection between the front rod 11 and the rear rod 21 can be made more convenient and the structure can be more compact. The pull rod 12 has a rotating shaft 121. The rotating shaft 121 is rotatably connected to the connecting member 32, and the rotating shaft 121 is rotatably engaged in the first bayonet 331. The locking member 31 has a pivot portion 311. The pivot portion 311 is pivotally connected to the front rod 11, and the pivot center axis is coaxial with the first pivot axis 112. The locking member 31 has a locking portion 312. The locking portion 312 is in the shape of a hook body, and the locking portion 312 can be engaged in the second bayonet 332. When the front frame 1 is unfolded relative to the rear frame 2, the rear end portion of the front rod 11 abuts against the front end portion of the rear rod 21. More specifically,

[0039] As Figure 5As shown, the opening direction of the first bayonet 331 intersects with the opening direction of the second bayonet 332. The opening direction of the first bayonet 331 faces the front of the detachable folding bike 100, and the opening direction of the second bayonet 332 faces the bottom of the detachable folding bike 100. Since the rotating shaft 121 can only slide out in the opening direction of the first bayonet 331 when it is stuck in the first bayonet 331, and the locking member 31 can only slide out in the opening direction of the second bayonet 332, therefore, by intersecting the second bayonet 332 with the first bayonet 331, when the locking portion 312 is engaged with the second bayonet 332 and the rotating shaft 121 is engaged with the first bayonet 331, the locking member 31 and the pull rod 12 can restrict each other, and further the locking member 31, the pull rod 12, the connecting member 32 and the engaging member 33 form a whole, so that the pull rod 12 and the rear rod 21 are pivotally connected to each other.

[0040] Please refer to again Figure 3 and Figure 4 The disassembly mechanism 3 further includes an elastic member 34, and the elastic member 34 is a tension spring. The locking member 31 is provided with a connecting portion 313, and the pull rod 12 is provided with a pin 122, and the pin 122 is coaxial with the rotating shaft 121. The two ends of the elastic member 34 are respectively connected to the connecting portion 313 and the pin 122. The elastic member 34 provides an elastic force for the locking portion 312 of the locking member 31 to enter the second bayonet 332. By providing the elastic member 34, it can prevent the locking portion 312 of the locking member 31 from accidentally disengaging from the second bayonet 332, avoid the accidental separation of the front frame 1 and the rear frame 2, and improve the safety of use.

[0041] Again, such as Figure 2 , Figure 3 and Figure 12 When the front frame 1 is unfolded relative to the rear frame 2, the pull rod 12 is in a horizontal state and is located below the locking member 31 to block the rotation of the locking member 31. Therefore, the locking portion 312 cannot exit the second bayonet 332. When the front frame 1 is folded relative to the rear frame 2, the pull rod 12 is in a vertical state and is located at the lower end of the locking member 31. Therefore, it does not block the rotation of the locking member 31 to unlock the locking member 31. At this time, rotating the locking member 31 can make the locking portion 312 exit the second bayonet 332. In this way, the locking member 31 can only be unlocked when the folding bike is folded, that is, the folding bike can only be disassembled when it is folded, thereby improving the safety of use.

[0042] Such as Figure 7As shown, the connecting member 32 has a transverse portion 321 and a vertical portion 322 fixedly connected to the transverse portion 321. The transverse portion 321 is located at the lower side of the front end of the rear rod 21, and the vertical portion 322 is located at the front end face of the rear rod 21. A positioning rib 323 is provided on one side of the connecting member 32, and the positioning rib 323 is located on the side surface of the vertical portion 322. A positioning groove 113 is provided at the front end portion of the front rod 11. When the front frame 1 is unfolded relative to the rear frame 2, the positioning rib 323 is engaged in the positioning groove 113. By the cooperation of the positioning rib 323 and the positioning groove 113, the front rod 11 and the rear rod 21 can be quickly positioned when unfolded, improving the convenience of operation.

[0043] Combined with Figure 8 As shown, the foldable and disassemblable bicycle 100 further includes a first driving mechanism 4. The first driving mechanism 4 is disposed on the front frame 1 and drives the front rod 11 and the rear rod 21 to fold them. By providing the first driving mechanism 4, the front frame 1 and the rear frame 2 can be conveniently folded or unfolded, improving the convenience of unfolding and folding. Specifically, the first driving mechanism 4 includes a first electric push rod 41, a first swing rod 42 and a second swing rod 43. The first swing rod 42 and the second swing rod 43 are symmetrically disposed on two inner sides of the foldable and disassemblable bicycle 100. One end of the first swing rod 42 is pivotally connected to the front rod 11. A pivot sleeve 324 is fixedly provided at the upper end of the connecting member 32. One end of the second swing rod 43 is pivotally connected to the pivot sleeve 324. The pivot sleeve 324 is located at the upper side of the front end of the rear rod 21. The other end of the first swing rod 42 is pivotally connected to the other end of the second swing rod 43. One end of the first electric push rod 41 is pivotally connected to the front frame 1 and the output end is connected to the first swing rod 42. Specifically, the first swing rods 42 located on two inner sides of the foldable and disassemblable bicycle 100 can be connected by a fixed shaft. The first electric push rod 41 can be disposed in the middle of the front frame 1, and the output end is pivotally connected to the fixed shaft, so as to push the two first swing rods 42 simultaneously. By using the first electric push rod 41, the front frame 1 and the rear frame 2 can be automatically folded and unfolded, greatly facilitating the operation of the user and improving the convenience of use.

[0044] Combined with Figure 9As shown, the detachable folding bicycle 100 further includes foldable seat folding brackets 5 symmetrically disposed on both sides of the rear frame 2 and a second driving mechanism 6 disposed in the middle of the rear frame 2. The second driving mechanism 6 can drive the seat folding brackets 5 to fold or unfold. By providing the second driving mechanism 6, the seat folding brackets 5 can be conveniently folded or unfolded, improving the convenience of unfolding and folding. Specifically, the seat folding bracket 5 includes a first rod 51, a second rod 52, a first driving rod 53, a seat post 54 and a linkage rod 55. The first rod 51 and the second rod 52 are cross - arranged and pivotally connected to each other in the middle. The upper end of the first rod 51 is pivotally connected to the front end of the seat post 54, and the lower end is pivotally connected to the rear wheel bracket 22. The upper end of the second rod 52 is pivotally connected to the lower end of the linkage rod 55, the lower end of the second rod 52 is pivotally connected to the upper end of the first driving rod 53, and the lower end of the first driving rod 53 is pivotally connected to the front end of the rear frame 2. The upper end of the linkage rod 55 is pivotally connected to the rear end of the seat post 54. The output end of the second driving mechanism 6 is connected to the first driving rod 53 to drive the first driving rod 53 to swing. The second driving mechanism 6 includes a second electric push rod 61, a second driving rod 62 and a connecting rod 63. One end of the second driving rod 62 is pivotally connected to the rear rod 21 and is coaxial with the pivot shaft at the lower end of the first driving rod 53. The other end of the second driving rod 62 is pivotally connected to the first driving rod 53 through a central shaft 64 and is coaxial with the pivot shaft at the upper end of the first driving rod 53. The connecting rod 63 is fixed to the second driving rod 62 and is pivotally connected to the output end of the second electric push rod 61. The second electric push rod 61 is pivotally connected to the rear frame 2.

[0045] Combining the above and in conjunction with Figure 1 、 Figures 10 to 13 , the working principle of the detachable folding bicycle 100 of the present invention will be described in detail as follows:

[0046] As shown in Figure 10 and Figure 11As shown, when folding, the first electric push rod 41 is activated. The output end of the first electric push rod 41 extends and pushes the fixed shaft. The fixed shaft drives the first swing rod 42 to swing, and the first swing rod 42 drives the second swing rod 43 to swing simultaneously. At this time, the rear end of the front rod 11 and the front end of the rear rod 21 swing upward, causing the front frame 1 to approach the rear frame 2. At the same time, the second electric push rod 61 is activated. The output end of the second electric push rod 61 extends and pushes the first driving rod 53 to swing. The first driving rod 53 drives the lower end of the second support rod 52 to swing upward, while the upper end of the second support rod 52 swings downward and drives the linkage rod 55 to rotate. The linkage rod 55 drives the rear end of the seat rod 54 downward and towards the first support rod 51, and the upper end of the linkage rod 55 rotates closer to the seat rod 54. During this process, the rear rod 21 also approaches the first support rod 51. Finally, the front frame 1, the rear frame 2, and the seat folding bracket 5 approach each other and fold up.

[0047] As Figure 12 and Figure 13 When disassembling is required after folding, manually pull the locking member 31 to make the locking member 31 rotate around the first pivot shaft 112, causing the locking portion 312 to leave the second bayonet 332. At this time, the components such as the pull rod 12, the front rod 11, the connecting member 32, and the locking member 31 are no longer laterally restricted, and the rotating shaft 121 can slide in the opening direction of the first bayonet 331. When the rotating shaft 121 disengages from the first bayonet 331, at this time, the components such as the front rod 11, the pull rod 12, the rotating shaft 121, the connecting member 32, the locking member 31, the first swing rod 42, and the second swing rod 43 disengage from the rear frame 2 and leave the rear frame 2 with the front frame 1. At this time, the front frame 1 and the rear frame 2 can be disassembled. When assembly is required, only need to bring the front frame 1 close to the rear frame 2, and the rotating shaft 121 is snapped into the first bayonet 331. Then drive the locking member 31 to rotate so that the locking portion 312 is snapped into the second bayonet 332. At this time, the front frame 1 can be connected to the rear frame 2, and the entire disassemblable folding bicycle 100 is in a folded state again. Finally, only need to control the first electric push rod 41 and the second electric push rod 61 to unfold the disassemblable folding bicycle 100.

[0048] Compared with the prior art, in the present invention, the connecting member 32 is pivotally connected to the front rod 11 through the first pivot shaft 112, the rotating shaft 121 of the pull rod 12 is rotatably connected to the connecting member 32 and is clamped in the first bayonet 331 of the engaging member 33, and the locking member 31 is pivotally connected to the first pivot shaft 112 and is simultaneously clamped in the second bayonet 332. Thereby, the connecting member 32 can be relatively fixedly connected to the rear rod 21, and a pivotal connection relationship can be formed between the front rod 11 and the pull rod 12 and the rear rod 21 respectively. Therefore, the front frame 1 can be rotatable relative to the rear frame 2 to achieve the purpose of being able to be folded together by approaching each other. Moreover, during folding, only the locking portion 312 of the locking member 31 needs to be detached from the second bayonet 332, thereby unlocking the pull rod 12, so that the rotating shaft 121 can be disengaged from the engaging member 33 from the first bayonet 331, and at the same time, the connecting member 32 can be disengaged from the rear rod 21. Therefore, the front frame 1, the locking member 31 and the connecting member 32 can be completely detached from the rear rod 21 to achieve the purpose of disassembling the folding bicycle into two parts, the front and the rear, which greatly facilitates carrying and storage and improves the convenience of use.

[0049] The above-disclosed are only the preferred examples of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
