[0040] See also Figures 1 to 4The present invention provides a folding bicycle, comprising a frame and four wheels connected to the frame; wherein the frame comprises a bottom frame that can be unfolded and folded, a top frame that can be unfolded and folded, and four support members connected between the bottom frame and the top frame, the bottom frame is connected to the four support members, and one support member is connected to one wheel; the top frame comprises four enclosure rod assemblies, each enclosure rod assembly comprises at least two first connecting rods, at least two first connecting rods are hinged to each other, and two first connecting rods located at the ends of the enclosure rod assembly are hinged to two support members in the length direction or the width direction of the folding bicycle; the folding bicycle has an open state and a folded state, when it is in the open state, the bottom frame and the top frame are both in the unfolded state, so that the four support members are away from each other, and the four wheels are away from each other; when the folding bicycle is in the folded state, the bottom frame and the top frame are both in the folded state, and the four support members and the wheels connected thereto are gathered together.

[0041] The folding cart 100 in the present embodiment is connected to four supporting members 12 via four foldable fence assemblies 13, each fence assembly 13 includes at least two first connecting rods 131, and at least two first connecting rods 131 are hinged to each other. The two first connecting rods 131 at the ends of the fence assembly 13 are hinged to the two supporting members 12 in the length direction or the width direction of the folding cart 100. In this way, the fence assembly 13 has a lower structural complexity, lower processing difficulty, and higher reliability. Moreover, when the folding cart 100 is retracted, it can be folded in both the length direction and the width direction at the same time. In addition, the overall volume of the fence assembly 13 is smaller, so that the cart occupies less space after being folded.

[0042] The bottom frame 11 and the top frame can be of the same structure or different structures. Generally, the bottom frame 11 is connected to the bottom end of the support member 12, and the first connecting rod 131 of the top frame is hinged to the top end of the support member 12. Of course, the bottom frame 11 and the top frame can also be connected to the upper and lower positions of the middle part of the support member 12, respectively, which is not limited here. The folding bicycle 100 is generally equipped with canvas, which is wrapped around each frame and the support member 12 and can be used to carry items. The position where the wheels 14 are connected to the support member 12 can be set according to actual conditions. Preferably, in some embodiments of the present invention, the wheels 14 are connected to the bottom end of the corresponding frame, so that the spacing between the wheels 14 is smaller after the folding bicycle 100 is folded, further reducing the space occupied by the folding bicycle 100 in the folded state.

[0043] In the above-mentioned enclosure rod assembly 13, the two first connecting rods 131 can be directly hinged. Furthermore, one end of the two first connecting rods 131 connected is provided with a positioning portion to achieve the rotation positioning of the two first connecting rods 131; the two first connecting rods 131 can also be hinged through other parts. Specifically, in some embodiments of the present invention, the enclosure rod assembly 13 further includes at least one first connecting member 132, and one end of the two first connecting rods 131 is hinged to the first connecting member 132. The two first connecting rods can be hinged to the first connecting member.

[0044] The above-mentioned surrounding rod assembly 13 may be provided with one first connecting member 132 and two first connecting rods 131, or may be provided with two first connecting members 132 and three first connecting rods 131. The specific composition of the surrounding rod assembly 13 may be set according to actual conditions, and is not limited here.

[0045] In some embodiments of the present invention, the bottom frame 11 includes at least one second connecting member 111 and four second connecting rods 112, one end of at least two second connecting rods 112 is hinged to the second connecting member 111, and one end of the second connecting rod 112 away from the second connecting member 111 is hinged to the bottom end of the corresponding supporting member 12. In this way, the articles placed in the folding cart can be supported by the second connecting member 111 and the four second connecting rods 112, and the maximum load-bearing weight of the folding cart is larger.

[0046] During the folding process of the folding bicycle 100, the two or more second connecting rods 112 connected to the second connecting member 111 rotate relative to each other, and at the same time, the two or more first connecting rods 131 connected to the first connecting member 132 rotate relative to each other, and the angle between the connecting rods connected to the same connecting member gradually approaches 0 degree from 180 degrees, and the supporting structure tightens toward the center.

[0047] The second connecting member 111 is generally configured in a plate shape, and of course, can also be configured in a block shape, a column shape, etc., depending on the specific situation. In some embodiments of the present invention, the second connecting member 111 is provided with a support plate, and one end of the four second connecting rods 112 is respectively hinged to the corners of the support plate. Using the support plate as the second connecting member 111 can provide a larger contact area and a stronger supporting force, thereby enhancing the structural stability of the entire bottom frame 11. When folding, the second connecting rods 112 surrounding the peripheral side of the support plate gather toward the top of the support plate to achieve simultaneous folding in multiple directions.

[0048] In some embodiments of the present invention, one end of each of the two first connecting rods 131 is respectively hinged to the opposite ends of each first connecting member 132, and the other end is respectively hinged to the top ends of the two corresponding supporting members 12 in the length direction or the width direction of the folding bicycle 100. When folding, each first connecting rod 131 is folded in the length direction and the width direction at the same time, and the top frame structure is simple and reliable, the overall volume is small, the space occupied after folding is small, and it is more lightweight.

[0049] For further convenience, in some embodiments of the present invention, the second connecting rod 112 is interference-fitted with the second connecting member 111. In this way, there is resistance when the first connecting member and the first connecting rod rotate relative to each other, and the user can adjust and fix the rotation angle of the first connecting member and the first connecting rod.

[0050] The top surface of the first connecting member 132 is provided with two hinge grooves 1321, and the groove walls on both sides of the two hinge grooves 1321 are separated from each other to form an escape opening 1322. One end of the first connecting rod 131 is installed in the hinge groove 1321 with damping rotation, and can be rotated and switched between the groove of the hinge groove 1321 and the escape opening 1322. The first connecting rod 131 can rotate freely in the hinge groove 1321 and switch to the escape opening 1322 when needed, providing flexible rotation and positioning functions, and facilitating the unfolding and folding of the folding bicycle 100. In addition, the damping rotation installation can reduce damage caused by rapid movement or impact, while providing a smooth rotation experience and avoiding instability caused by vibration.

[0051] In some embodiments of the present invention, four support structures are provided, the top frame includes four first connecting members 132 and eight first connecting rods 131, and four second connecting rods 112 are provided. With the support of four support structures, the folding bicycle 100 has better stability and load-bearing capacity in the unfolded state, can carry more loads, and has a larger volume inside the bicycle. The four support structures and the corresponding top frame and bottom frame 11 components form a symmetrical layout, which helps to evenly distribute weight and pressure and improve the balance of the folding bicycle 100.

[0052] In order to prevent the second connector 111 from scratching each first connector 132 during folding, in some embodiments of the present invention, the second connector 111 is vertically staggered with each first connector 132. The staggered second connector 111 and first connector 132 have more room for movement during the folding process, which helps to reduce mutual interference during folding.

[0053] In some embodiments of the present invention, the support member 12 is an L-shaped guard plate, and when the folding cart 100 is in a folded state, each L-shaped guard plate is enclosed in a cylindrical shape. When folded, the L-shaped guard plates can be tightly enclosed in a cylindrical shape, which is relatively compact and convenient for storage and carrying. Furthermore, when the folding cart 100 is in a folded state, the folding rod assembly formed by the top frame and the bottom frame 11 is fully or partially enclosed in the cylindrical structure enclosed by the L-shaped guard plates. The L-shaped guard plates have excellent mechanical properties and can provide better structural stability and strength after being enclosed, thereby enhancing the durability of the folding cart 100, and the cylindrical structure formed in the folded state can protect the internal connecting rods, wheels 14 and other components, thereby reducing damage during transportation or storage.

[0054] In some embodiments of the present invention, the inner side surface 123 of the L-shaped guard plate is provided with a bottom hinge portion 121 for the second connecting rod 112 to be hinged, and a top hinge portion 122 for the first connecting rod 131 to be hinged, and the bottom hinge portion 121 and the two top hinge portions 122 are staggered in the vertical direction. By staggering the bottom hinge portion 121 and the top hinge portion 122 on the L-shaped guard plate, a more compact layout can be achieved in a limited space, thereby improving the folding efficiency and space utilization of the folding vehicle 100. The staggered bottom hinge portion 121 and the two top hinge portions 122 can also effectively avoid mutual interference between the second connecting rod 112 and the first connecting rod 131 when folding, ensuring that the connecting rods can move smoothly and reducing jamming and wear. The L-shaped guard plate can be set as an angular guard plate, or it can be set as a curved guard plate, which is not limited here.

[0055] In some embodiments of the present invention, when the folding bicycle 100 is in the folded state, the four second connecting rods 112 are inclined in the vertically upward direction toward each other. In this way, when the folding bicycle 100 is unfolded, the support plate can be directly pressed from above, and the support plate abuts against the second connecting rods 112, and the second connecting rods 112 are unfolded by the component force that opens outward, which greatly improves the convenience of use.

[0056] In some embodiments of the present invention, the folding scooter 100 further includes a handle 15, which is connected to two supporting members 12 in the length direction of the folding scooter 100. In this way, the user can move and carry the folding scooter 100 by the handle 15, which is more convenient. In addition, the handle 15 is connected to the two supporting members 12 in the length direction of the folding scooter 100, so that the forces on both sides of the folding scooter 100 are more uniform when pulling, and no twisting occurs.

[0057] In some embodiments of the present invention, the handle 15 includes a gripping portion 151 and two connecting portions 152, one end of the two connecting portions 152 is respectively connected to the two ends of the gripping portion 151, and the other end of the two connecting portions 152 is detachably connected to the corresponding support member 12. In this way, the user can remove the handle 15 and install it when needed, which is more convenient, and the folding and unfolding of the folding bicycle 100 will not be affected after the handle 15 is removed.

[0058] There are many ways to detachably connect the connection part 152 and the support member 12. For example, a plug is provided at the end of the connection part 152, and a socket is provided on the outer surface of the support member 12. The plug and the socket can be easily inserted and removed to achieve quick connection and disconnection. The connection part 152 and the support member 12 can also be connected by a screw buckle or a thread, which is not specifically limited here.

[0059] In some embodiments of the present invention, the folding bicycle 100 further includes a traction member, the two ends of which are respectively connected to two support members 12 away from the handle 15. The traction member may be in the shape of a belt, a chain, or a rod, etc. The traction member enables the user to pull the folding bicycle 100 from a greater distance, thereby increasing the convenience of movement.

[0060] In some embodiments of the present invention, a positioning structure is provided at the hinge position between the second connecting member 111 and the four second connecting rods 112, and the positioning structure is at least used to position the bottom frame 11 to maintain the unfolded state, so that the folding bicycle 100 is not easily deformed by external forces, and is convenient for users to use.

[0061] There are many specific implementations of the above positioning structure. Preferably, in some embodiments of the present invention, the positioning structure includes a squeeze fit position between the second connecting member 111 and the second connecting rod 112. When the second connecting member 111 and the second connecting rod 112 have a tendency to rotate relative to each other, the squeeze fit position rubs against each other to limit the relative rotation of the second connecting member 111 and the second connecting rod 112. In this way, the second connecting member 111 and the second connecting rod 112 can be prevented from being easily deformed by external forces, and the user has a good force feedback effect when adjusting, and a better user experience.

[0062] In other embodiments of the present invention, the positioning structure further includes a stopper, and when the bottom frame 11 is unfolded, the stopper prevents the second connecting rod 112 from rotating upward relative to the second connecting member 111, so that the bottom frame 11 is positioned in the unfolded state. Specifically, for example, the stopper is a convexity integrally formed on the second connecting member 111, and the second connecting rod 112 is provided with a slot. After the second connecting member 111 rotates to the right position relative to the second connecting rod 112, the convexity is inserted into the slot, thereby achieving positioning.

[0063] In some embodiments of the present invention, a limiting structure is provided at the hinged position between the second connecting member 111 and the corresponding bottom hinge portion 121, and the limiting structure positions the bottom frame 11 in the unfolded state at least when the bottom frame 11 is unfolded. The limiting structure has a similar function to the above-mentioned positioning structure, and therefore, the specific implementation of the limiting structure can refer to the above-mentioned positioning structure, which will not be described in detail here.

[0064] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
