First embodiment
As shown in fig. 1 to 6, in the present embodiment, the vehicle frame 1 includes
The push handle 11, the rear leg 12, the handle 13 and the first connecting piece 14, wherein the upper sides of the handle 13 and the first connecting piece 14 are pivoted with the push handle 11, the lower sides of the handle 13 and the first connecting piece 14 are pivoted with the rear leg 12, and the push handle 11, the rear leg 12, the handle 13 and the first connecting piece 14 form a four-bar structure;
a front foot 15, the rear side of the front foot 15 is rotationally connected with the rear foot 12 or the rider 13 or the first connector 14, or the rear side of the front foot 15 and the lower side of the rider 13 are coaxially and rotationally connected with the rear foot 12;
the second connecting piece 16 is rotatably connected with the rear foot 12, and the second connecting piece 16 is also rotatably connected with the driver 13 and can move up and down relative to the driver 13;
a third connecting element 17, wherein the front side of the third connecting element 17 is rotatably connected with the front foot 15, and the rear side is rotatably connected with the second connecting element 16.
The front wheel 2 is connected to the front lower part of the front leg 15, and the rear wheel 3 is connected to the rear lower part of the rear leg 12.
The lower side of the rider 13 is pivoted to the rear leg 12 through a first rotating shaft 121, the lower side of the first connecting member 14 is pivoted to the rear leg 12 through a second rotating shaft 122, and the first rotating shaft 121 is located at the rear side of the second rotating shaft 122.
When the frame is to be folded, the locking mechanism is unlocked first, and then the frame 1 can be folded, and the specific operation is as follows: so that the upper side of the push handle 11 rotates forwards and downwards and the lower side of the push handle 11 rotates backwards and downwards, because of the characteristics of the four-bar linkage structure, the rider 13 and the first connecting piece 14 are driven to rotate backward and downward to approach the rear leg 12, so that the upper side of the second connecting piece 16 is also driven to rotate backwards and downwards, and simultaneously the upper side of the second connecting piece 16 rotates relative to the handle 13 and moves along the handle 13 towards the pivoting direction of the handle 13 and the push handle 11, in this way, the third connecting member 17 whose rear side is rotatably connected to the second connecting member 16 is also pulled to be rotationally moved backward, the front leg 15 is driven to rotate to approach the rear leg 12 until the push handle 11, the rider 13, the rear leg 12, the front leg 15, the first coupling 14, the second coupling 16, and the third coupling 17 are relatively close, the frame 1 is completely folded (as shown in fig. 5 and 6), and the front road 2 is also close to the rear wheel 3.
That is, because the structure of the frame 1, the components of the frame 1 can be folded by linkage as long as the upper side of the push handle 11 rotates forwards and downwards and the lower side of the push handle 11 rotates backwards and downwards, so that the folding operation of the frame 1 is very simple, and because the components are relatively close after the frame 1 is folded, the material volume is small, and the frame is convenient to store and carry.
In the unfolded state of the frame 1, the connection point 160 of the second connecting member 16 to the rider 13 is located on the upper side of the connection point 161 of the second connecting member 16 to the rear leg 12. Thus, when the frame 1 is folded, the upper side of the second connector 16 can move a longer distance relative to the rider 13, so that the front leg 15 and the rear leg 12 can be closer by the driving of the third connector 17, thereby further reducing the volume of the folded frame 1.
When the frame 1 is in the unfolded state, the connection point 160 of the second connecting piece 16 and the rider 13, the connection point 161 of the second connecting piece 16 and the rear leg 12, and the connection point 162 of the third connecting piece 17 and the second connecting piece 16 form a triangle or are on the same straight line. That is, in the unfolded state of the frame 1, the junction 160 between the upper side of the second connecting member 16 and the rider 13, the connection point 161 between the second connecting member 16 and the rear leg 12, and the connection point 163 between the third connecting member 17 and the second connecting member 16 are formed in a triangular shape (as shown in fig. 1) or are aligned in a straight line.
The second connecting member 16 may be formed in a V shape, the V shape is formed in a V shape that is opened toward a side, one end of the V-shaped second connecting member is rotatably connected to the rear leg 12, the other end of the V-shaped second connecting member is rotatably connected to the rider 13 and can move up and down relative to the rider 13, and a rear side of the third connecting member 17 is rotatably connected to a turning point of the V-shaped second connecting member 16. Thus, when the frame 1 is folded, the rear end of the third connector 17 can rotate by a larger radian, so that the front leg 15 can be driven by the third connector 17 to rotate by a larger angle to be closer to the rear leg 12, and the volume of the folded frame 1 is further reduced.
The second coupling member 16 may be formed in an arc shape or other shapes, and the rider 13, the rear side of the front leg 15 and the rear leg 12 are coupled to the second coupling member 16 at different positions.
The second coupling member 16 may be configured in a straight rod shape, and the rider 13, the rear side of the front leg 15 and the rear leg 12 are coupled to different positions of the straight rod-shaped second coupling member 16, so that the coupling point 160 of the second coupling member 16 to the rider 13, the coupling point 161 of the second coupling member 16 to the rear leg 12, and the coupling point 162 of the third coupling member 17 to the second coupling member 16 are all aligned with each other.
In this embodiment, the connection point 162 of the third connecting member 17 and the second connecting member 16 is located below the connection point 160 of the second connecting member 16 and the rider 13.
In this embodiment, the upper side of the second connecting member 16 is rotatably connected to the rider 13 through a third rotating shaft, the third rotating shaft can move up and down along the rider 13, for example, a long hole 131 extending up and down is provided on the rider 13, and the third rotating shaft penetrates through the long hole 131 and can move along the extending direction of the long hole; or, a sliding member (not shown) capable of moving up and down relative to the rider 13 is disposed on the rider 13, and the upper side of the second connecting member 16 is pivoted to the moving member, so that the upper side of the second connecting member 16 is rotatably connected to the rider 13 and can move up and down relative to the rider 13.
Preferably, in the unfolded state of the frame 1, the connection point 170 of the front side of the third connecting element 17 and the front foot 15, the connection point 162 of the rear side and the second connecting element 16, and the connection point 161 of the second connecting element 16 and the rear foot 12 are on the same straight line, so that in the unfolded state of the frame 1, the frame 1 can bear larger force, the structure is more stable, and the frame 1 in the unfolded state is more stable.
Preferably, when the rear side of the front foot 15 is rotatably connected with the rider 13, in the unfolded state of the frame 1, the connection point of the front foot 15 and the rider 13 is located below the connection point of the second connecting piece 16 and the rider 13. In this way, under the pulling of the third connecting element 17, the angle that the front leg 15 can rotate backward is larger, so that the front leg can be closer to the rear leg 12, and the volume of the folded frame 1 is smaller.
The locking mechanism is not the invention of the present invention, and can be disposed between the two connected to the frame 1, and can be any known and available prior art, and therefore, is not described herein.
