[0038] The technical solution of the present invention will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0039] Example 1: Refer to Figures 1 to 8 As shown, a novel connection structure between a children's vehicle and a bicycle includes:

[0040] A head connector 1 is provided with a connector 11, a limiting groove 12 is provided in the circumferential direction of the connector 11, and a chamfered section is provided at the end of the connector 11.

[0041] A tow head connector assembly 2 is used to connect a trailer rod 3 and a tow head connector 1. The tow head connector assembly 2 includes a tow head base 21, which has a first connecting hole 211 along its axial direction and a base mounting groove 212 along its radial direction. The base mounting groove 212 intersects with the first connecting hole 211. A limit button 22 and a limit spring 23 are provided in the base mounting groove 212. The limit spring 23 abuts between the limit button 22 and the bottom of the base mounting groove 212. A limit through hole 221 is provided on the limit button 22. The limit through hole 221 includes a first limit arc and a second limit arc. The diameter of the first limit arc is larger than the diameter of the second limit arc. The diameter of the first limit arc is larger than the diameter of the connector. The diameter of the second limit arc matches the limit groove.

[0042] The connector 11 is disposed in the first connecting hole 211 and passes through the limiting through hole 221. The limiting spring 23 pushes the limiting button 23 so that the inner wall of the limiting through hole 221 abuts against the limiting groove 12, thereby connecting the head connector 1 and the head connector assembly 2.

[0043] A head cover 24 is provided on the outer circumference of the head base 21, and the head cover 24 slides along the head base 21. An outer spring 25 is provided between the head base 21 and the head cover 24. A first abutment portion 241 is provided on the inner sidewall of the head cover 24, and a second abutment portion 213 is provided on the circumference of the head base 21. The two ends of the outer spring 25 abut against the first abutment portion 241 and the second abutment portion 213, respectively. Through the force of the outer spring 25, the head cover 24 moves towards the limit button 22, thus covering the limit button 22 and protecting it.

[0044] A guide groove 214 is provided on the outer circumferential side wall of the head base 21 along its axial direction, and a guide bar 242 that mates with the guide groove 214 is provided on the inner side wall of the head sleeve 24. Through the cooperation between the guide bar 242 and the guide groove 214, the head sleeve 24 can slide stably along the head base 21.

[0045] A head end cap 26 is provided at the end of the head base 21 near the head connector 1. The head end cap 26 has an end cap hole 263. A protruding ring 261 is provided in the circumferential direction of the head end cap 26. The protruding ring 261 is sleeved on the end of the head base 21 and is connected to the end of the head base 21 by a screw 264. A pressing hole 262 is provided on the end face of the protruding ring 261. The pressing hole 262 cooperates with the button part 222. Abutting parts 224 are provided on both sides of the button part 222 in the length direction. Under the action of the elastic force of the limiting spring 23, the abutting parts 224 abut against the edge of the pressing hole 262. Through the limiting effect of the protruding ring 261 on the edge of the pressing hole 262 on the abutting part 224, the limiting button 22 can be restricted in the limiting groove 12. At the same time, the end cap 26 can limit the end cap 24 to prevent the end cap 24 from falling off the end cap base 21.

[0046] The head base 21 is provided with a second connecting hole 215 along its axial direction. The second connecting hole 215 is located at the end away from the first connecting hole 211. The second connecting hole 215 and the first connecting hole 211 are connected. The trailer connecting pipe 4 is provided in the second connecting hole 215. The end of the trailer connecting pipe 4 away from the second connecting hole 215 is connected to the trailer rod 3.

[0047] The installation steps in this embodiment are as follows: The installation steps of the head connector assembly 2 are as follows: First, place the limiting spring 23 at the bottom of the base mounting groove 212. Then, place the limiting button 22 inside the base mounting groove 212, so that the limiting spring 23 abuts against the bottom of the base mounting groove 212 and the limiting button 22. Next, sleeve the outer spring 25 on the outer peripheral wall of the head base 21. Then, sleeve the head outer sleeve 24 on the outer peripheral wall of the head base 21, so that the two ends of the outer spring 25 abut against the first abutting part 241 and the second abutting part 213 respectively. Finally, install the head end cap 26... The protruding ring 261 is sleeved on the outer circumference of the head base 21, so that the pressing hole 262 corresponds to and matches the position of the limit button 22. The button part 222 is located inside the pressing hole 262. Under the action of the limit spring 23, the abutting part 224 on the limit button 22 abuts against the protruding ring 26 on the edge of the pressing hole 262. Finally, the head end cap 26 is fixedly connected to the head base 21 by screws 264. Under the action of the outer spring 25, the head outer sleeve 24 can cover the limit button 22, and the head end cap 26 limits the head outer sleeve 24. Figure 3As shown, the connection steps between the head assembly 2 and the head connector 1 are as follows: The connector 11 is inserted into the end cap hole 263. When the chamfered section at the end of the connector 11 abuts against the side of the first limiting arc of the limiting through hole 221, the limiting button 22 moves downward against the force of the limiting spring 23. After the limiting button 22 moves downward a certain distance, the limiting button 22 stops moving downward. The connector 11 slides horizontally along the limiting through hole 221. When the limiting groove 12 slides to the side of the first limiting arc... When the components come into contact, the limit button 22 is subjected to the force of the limit spring 23, causing the limit button 22 to move upward, so that the second limit arc engages in the limit groove 12, realizing the connection between the connector 11 and the head connector assembly 2. Then, the head base 21 is connected to the trailer connecting pipe 4, and the trailer connecting pipe 4 is connected to the trailer rod 3, thus completing the overall structural connection. In actual use, the head connector 1 can be connected to the rear wheel axle of a bicycle, and then the trailer rod 3 can be connected to a children's vehicle. Similarly, when it is necessary to remove the connector 11 from the head connector assembly 12, push the head sleeve 24 to expose the limit button 22 in the head base 21, and then press the limit button 22, so that the limit button 22 moves downward against the force of the limit spring 23, causing the connector 11 to disengage from the limit through hole 221, thus realizing the separation between the connector 11 and the head connector assembly 2.

[0048] In this embodiment, the mutual restraint between the parts during assembly makes it very convenient to install and disassemble the head connector assembly 2. In particular, the invention uses only one screw 264 to connect and mate all the parts in the head connector assembly 2, making the installation of the head connector assembly 2 very convenient. At the same time, since this embodiment uses the limit button 22, the limit spring 23 and the connector 11 to cooperate, the connection and disassembly between the connector 11 and the head connector assembly 2 are very convenient. Furthermore, since the limit groove 12 and the limit through hole 221 cooperate, the connector 11 can rotate relative to the limit through hole 221, making the connection between the connector 11 and the head connector assembly 2 even more convenient.

[0049] Example 2: Refer to Figures 1 to 8As shown, this embodiment is similar in structure to Embodiment 1, except that the trailer connecting pipe 4 has a first pin hole 41 at its end near the second connecting hole 215, and a base pin hole 216 that mates with the first pin hole 41 is provided on the side wall of the second connecting hole 215. The trailer connecting pipe 4 passes through the second connecting hole 215, and the second connecting hole 215 and the trailer connecting pipe 4 are connected by a first pin 5. The trailer connecting pipe 4 has a second pin hole 42 at its end near the trailer rod 3, and a trailer rod pin hole 31 that mates with the second pin hole 42 is provided on the trailer rod 3. The trailer connecting pipe 4 passes through the trailer rod 3, and the second pin hole 42 and the trailer rod pin hole 31 are connected by a second pin 6.

[0050] The connection between the headstock base 21, the trailer connecting pipe 4, and the trailer rod 3 can be made very convenient and quick through the first pin 5 and the second pin 6.

[0051] Example 3: Reference Figures 1 to 8 As shown, this embodiment is similar in structure to Embodiment 1 or Embodiment 2, except that a self-locking structure is formed by the cooperation between the head sleeve 24 and the limit button 22. The specific structure of the self-locking structure is as follows: the radial length of the head sleeve 24 is greater than or equal to the radial length of the base mounting groove 212, so that when the head sleeve 24 is covered by the force of the sleeve spring 25 and covers the base mounting groove 212, the end of the limit bracket 223 of the limit button 22 abuts against the head sleeve 24, so that the head sleeve 24 restricts the limit bracket 223 and prevents the connector 11 from falling off the limit hole 221 due to the accidental downward movement of the limit bracket 223.

[0052] Therefore, in this embodiment, the steps for connecting the connector 11 and the head connector assembly 2 are different from those in embodiment 1. When connecting the connector 11 and the head connector assembly 2, it is necessary to push the head sleeve 24 to expose the base mounting groove 212. This allows the limit button 22 to move downward under the action of the connector 11, and the end of the limit bracket 223 to lose the restriction of the head sleeve 22, so that the limit button 22 can move downward.

[0053] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Other variations and modifications may be made without departing from the technical solutions described in the claims.
