[0069] Combination Figures 1 to 8 As shown, the folding bicycle of the utility model comprises:

[0070] Folding assembly 100;

[0071] A locking assembly 200, wherein the locking assembly 200 is mounted on the folding assembly 100;

[0072] Wherein, the folding assembly 100 includes a first folding component 110 and a second folding component 120;

[0073] The first folding component 110 and the second folding component 120 include a fixed state and a movable state;

[0074] When the first folding member 110 and the second folding member 120 are in a fixed state, the locking assembly 200 is locked, and at this time, the first folding member 110 and the second folding member 120 are fixedly connected;

[0075] When the first folding component 110 and the second folding component 120 are in an active state, the locking assembly 200 is not locked, and at this time, the first folding component 110 and the second folding component 120 are movably connected.

[0076] According to the folding bicycle of the embodiment of the utility model, the state of the folding assembly 100 is controlled by the locking assembly 200. The first folding component 110 and the second folding component 120 can be movably connected by pressing the locking assembly 200. At this time, the first folding component 110 can be rotatably connected with the second folding component 120. When the first folding component 110 and the second folding component 120 are unfolded, the locking assembly 200 rebounds, thereby locking the first folding component 110 and the second folding component 120 again. The specific state is described in the specific embodiment. The folding of the folding bicycle can be controlled more conveniently by the locking assembly 200, and there is no need to fix the folding part with bolts.

[0077] In one embodiment, the first folding component 110 includes a rear wheel mounting seat 111, a connecting member a 112 and a limiting structure 113;

[0078] The connecting member a 112 is mounted on one side of the rear wheel mounting seat 111;

[0079] The limiting structure 113 is symmetrically mounted on the connecting member a 112;

[0080] The rear wheel mounting seat 111 is provided with a push rod mounting portion 119 .

[0081] In this embodiment, the rear wheel mounting seat 111 is used to mount the rear wheel of the folding bicycle, and the rear wheel does not need to be removed when folding. Since the focus of this application is the folding state, not many irrelevant structures are proposed in the text. The connecting member a 112 is used to facilitate the installation of the rear wheel mounting seat 111 and the second folding component 120, the limiting structure 113 is used to limit the locking assembly 200, and the push rod mounting portion 119 is used to install the push rod to facilitate adults to push the folding bicycle.

[0082] In one embodiment, the second folding member 120 includes a connecting member b 121, a fixing rod 122 and a front wheel mounting portion 123;

[0083] The connecting member b 121 is installed on the connecting member a 112, and the connecting member a 112 is provided with a mounting cavity 124 whose size matches that of the connecting member b 121;

[0084] The fixing rod 122 is fixedly mounted on a side of the connecting member b 121 away from the connecting member a 112;

[0085] The front wheel mounting part 123 is mounted on an end of the fixing rod 122 away from the connecting part b121;

[0086] The seat mounting portion 125 is mounted on the connecting member b.

[0087] In this embodiment, the connector a 112 and the connector b 121 are connected to connect the rear wheel mounting seat 111 to the fixing rod 122, the front wheel mounting portion 123 is used to mount the front wheel of the folding vehicle, and the seat mounting portion 125 is used to mount the seat, which needs to be removed when folding.

[0088] In one embodiment, the limiting structure 113 includes a limiting cover a 114 and a limiting cover b 115;

[0089] The limiting cover body a 114 and the limiting cover body b 115 are symmetrically mounted on the connecting member a 112 with respect to the central axis of the connecting member a 112;

[0090] A latch 117 is installed between the position-limiting cover a 114 and the position-limiting cover b 115, and the latch 117 sequentially penetrates the position-limiting cover a 114, the connecting piece a 112, the connecting piece b 121 and the position-limiting cover b 115;

[0091] The sides of the limiting cover a 114 and the limiting cover b 115 that are away from each other are both in contact with the limiting members 118 , and the limiting members 118 are symmetrically fixedly disposed at the two ends of the latch 117 .

[0092] In this embodiment, by installing the latch 117, the connector a 112 can be movably connected to the connector b 121 when it is not locked, and the limiting cover a 114, the limiting cover b 115, the connector a 112 and the connector b 121 all begin to have through holes whose central axes overlap with each other, so that the latch 117 can sequentially penetrate the limiting cover a 114, the connector a 112, the connector b 121 and the limiting cover b 115.

[0093] In one embodiment, both sides of the connecting member a 112 are provided with fixing grooves 1121;

[0094] A convex block 116 whose size matches that of the fixing groove 1121 is formed on one side of the limiting cover body a 114 and the limiting cover body b 115 , and the convex block 116 is located in the fixing groove 1121 .

[0095] In this embodiment, when the protrusion 116 is stuck in the fixing groove 1121, it prevents the connection member a 112 and the connection member b 121 from rotating while driving the limiting cover body a 114 and the limiting cover body b 115 to rotate, so that the locking assembly 200 cannot be ejected, resulting in the connection member a 112 and the connection member b 121 being unable to be fixed when unfolded.

[0096] In one embodiment, a locking groove a1211 is formed on one side of the connecting member b 121;

[0097] A locking groove b 1212 is defined on one side of the connecting member b 121 away from the locking groove a 1211 .

[0098] In this embodiment, the locking groove a 1211 and the locking groove b 1212 are used to facilitate the installation of the locking assembly 200.

[0099] In one embodiment, the locking assembly 200 includes a pressing block 210, a spring 220 and a locking block 230;

[0100] The position limiting cover body a 114 and the position limiting cover body b 115 are both provided with a pressing hole 2101 adapted to the pressing block 210, and a pressing block 210 is disposed in each of the pressing holes 2101;

[0101] An annular extension block 2102 is disposed on one side edge of the pressing block 210, and a stopper 2103 matching the size of the annular extension block 2102 is disposed on the inner wall of the pressing hole 2101;

[0102] A top block 2104 is fixedly provided on one side of the pressing block 210 facing the connecting member a 112;

[0103] The spring 220 is disposed in both the locking groove a 1211 and the locking groove b 1212, one end of the spring 220 in the locking groove a 1211 is fixedly disposed on the inner wall of the locking groove a 1211, and one end of the spring 220 in the locking groove b 1212 is fixedly disposed on the inner wall of the locking groove b 1212;

[0104] Both sides of the connecting member a 112 are provided with through holes 1122 that are adapted to the sizes of the locking groove a 1211 and the locking groove b 1212, and the length of the top block 2104 is consistent with the depth of the through holes 1122;

[0105] The locking block 230 is fixedly disposed on one end of the spring 220 in the locking groove a 1211 away from the locking groove a 1211 and one end of the spring 220 in the locking groove b 1212 away from the locking groove b 1212.

[0106] In this embodiment, the user presses the two pressing blocks 210, and after being pressed, the pressing block 210 is subjected to pressure and moves in the pressing hole 2101. The cross section of the pressing block 210 above the annular extension block 2102 is smaller than the aperture of the pressing hole 2101, so when the pressing block 210 is locked, part of it extends to the outside of the pressing hole 2101. It is explained here that after the pressing block 210 moves, it pushes the locking block 230 to move through the top block 2104, and the locking block 230 squeezes the spring 220. At this time, the spring 220 is in a compressed state, and the locking block 230 is pushed out of the through hole 1122 on the connecting member a 112. At this time, there is no obstacle between the connecting member a 112 and the connecting member b 121. Through the limitation of the latch 117, the connecting member a 112 and the connecting member b 121 can be rotatably connected, thereby completing the folding action. When the connecting member a 112 and the connecting member b 121 are unfolded again, the connecting member a 112 and the connecting member b 121 are folded. When the two through holes 1122 of 112 coincide with the central axes of the locking groove a 1211 and the locking groove b 1212 again, the locking block 230 pops out again and is respectively stuck in the two through holes 1122 through the restoring force of the spring 220, thereby fixing the connecting member a 112 and the connecting member b 121 again. The length of the top block 2104 is consistent with the depth of the through hole 1122, so that when the top block 2104 is fully inserted into the through hole 1122 of the connecting member a 112, the top block 2104 will not extend too long into the locking groove a 1211 or the locking groove b 1212, thereby failing to complete the folding action. When the depth is consistent, the connecting member a 112 or the connecting member b 121 can be directly rotated to complete the folding action.

[0107] In one embodiment, when the first folding component 110 and the second folding component 120 are in a fixed state, the locking groove a 1211 coincides with the central axis of the through hole 1122 on the connecting member a 112 on one side of the locking groove a 1211, and the locking groove b 1212 coincides with the central axis of the through hole 1122 on the connecting member b 121 on one side of the locking groove b 1212. The locking block 230 is squeezed by the spring 220. At this time, one of the locking blocks 230 is located in the through hole 1122 on the connecting member a 112 on one side of the locking groove a 1211, and the other locking block 230 is located in the through hole 1122 on the connecting member b 121 on one side of the locking groove b 1212. The annular extension block 2102 on the pressing block 210 abuts against one side of the stopper 2103. At this time, the connecting member a 112 and the connecting member b 121 are in contact with each other. 121 is fixedly connected, the first folding component 110 is fixedly connected to the second folding component 120;

[0108] When the first folding component 110 and the second folding component 120 are in an active state, the locking block 230 is pushed out of the through hole 1122 on the connecting member a 112 by the pushing block 2104 on the pressing block 210. At this time, one of the locking blocks 230 is completely located in the locking groove a 1211, and the other locking block 230 is completely located in the locking groove b 1212. At this time, the connecting member a 112 and the connecting member b 121 are movably connected, and the first folding component 110 and the second folding component 120 are movably connected.

[0109] The working principle of this utility model:

[0110] The user presses the two pressing blocks 210, and after being pressed, the pressing block 210 is subjected to pressure and moves in the pressing hole 2101. The cross section of the pressing block 210 above the annular extension block 2102 is smaller than the aperture of the pressing hole 2101, so when the pressing block 210 is locked, part of it extends to the outside of the pressing hole 2101. It is explained here that after the pressing block 210 moves, the locking block 230 is pushed to move by the top block 2104 at the same time, and the locking block 230 squeezes the spring 220. At this time, the spring 220 is in a compressed state, and the locking block 230 is pushed out of the through hole 1122 on the connecting member a 112. At this time, there is no obstacle between the connecting member a 112 and the connecting member b 121. Through the limitation of the latch 117, the connecting member a 112 and the connecting member b 121 can be rotatably connected, thereby completing the folding action. When the connecting member a 112 and the connecting member b 121 are unfolded again, the connecting member a 112 and the connecting member b 121 are folded. When the two through holes 1122 of 112 coincide with the central axes of the locking groove a 1211 and the locking groove b 1212 again, the locking block 230 pops out again and is respectively stuck in the two through holes 1122 through the restoring force of the spring 220, thereby fixing the connecting member a 112 and the connecting member b 121 again. The length of the top block 2104 is consistent with the depth of the through hole 1122, so that when the top block 2104 is fully inserted into the through hole 1122 of the connecting member a 112, the top block 2104 will not extend too long into the locking groove a 1211 or the locking groove b 1212, thereby failing to complete the folding action. When the depth is consistent, the connecting member a 112 or the connecting member b 121 can be directly rotated to complete the folding action.

[0111] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the paper version and the contents of the drawings of the utility model under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the utility model.
