[0048] In some embodiments, the locking mechanism 3 comprises a base link 31 fixedly connected with the base 1, an inner seat link 32 fixedly connected with the inner seat 2, and a locking rotating wheel 33 hingedly connected with the base 1, the locking rotating wheel 33 being arranged in parallel with the hinging shaft of the base 1, the base link 31, and the inner seat link 32, the locking rotating wheel 33 being provided with a base locking groove 331 and an inner seat locking groove 332, the inner seat locking groove 332 being provided with a locking force receiving portion 333 on a side close to the base locking groove 331, and an unlocking force receiving portion 334 on a side away from the base locking groove 331.

[0049] When the inner seat 2 is placed into the mounting cavity 11 on the base 1, the inner seat link 32 on the inner seat 2 is pressed against the locking force receiving portion 333, driving the locking rotating wheel 33 to rotate in a forward direction, so that the inner seat link 32 enters the inner seat locking groove 332, and the base link 31 enters the base locking groove 331, so as to lock the inner seat 2 with the base 1.

[0050] When the inner seat 2 is taken out of the mounting cavity 11 on the base 1, the inner seat link 32 on the inner seat 2 is pressed against the unlocking force receiving portion 334, driving the locking rotating wheel 33 to rotate in a reverse direction, so that the inner seat link 32 exits the inner seat locking groove 332, and the base link 31 exits the base locking groove 331, so as to unlock the inner seat 2 with the base 1.

[0051] The locking mechanism 3 of the present embodiment automatically realizes the locking and unlocking of the inner seat 2 with the base 1 in cooperation with the actions of placing and taking out the inner seat 2, without the need for additional operations by the user, and is convenient to use. Moreover, the locking mechanism 3 of the present embodiment is organically coordinated through the base link 31 fixedly connected with the base 1, the inner seat link 32 fixedly connected with the inner seat 2, and the locking rotating wheel 33 hingedly connected with the base 1, when the inner seat 2 is connected with the base 1, the locking rotating wheel 33 simultaneously locks the base link 31 and the inner seat link 32, thereby stably connecting the inner seat 2 with the base 1, in the process of vehicle driving, in the face of complex working conditions such as bumps, sudden braking, sharp turns, etc., even if subjected to a larger external force impact, due to the synergistic locking effect between the locking rotating wheel 33 and the base link 31 and the inner seat link 32, the inner seat 2 and the base 1 can also be stably connected, greatly reducing the risk of separation of the inner seat 2 from the base 1 due to accidental circumstances, and providing a higher level of safety guarantee for children riding.

[0052] The locking force receiving part 333 is designed in an arc shape, and the arc of the arc shape is determined by simulation and actual test optimization. The arc shape not only can smoothly abut and conduct force with the inner seat connecting rod 32, but also can naturally and smoothly abut with the inner seat connecting rod 32 when the inner seat 2 gradually approaches the base 1 during assembly. Then, with the continuous downward movement of the inner seat 2, the locking rotating wheel 33 can stably rotate downward, guiding the inner seat connecting rod 32 to smoothly slide into the base locking groove 331 along the locking force receiving part 333, achieving precise clamping cooperation, without the need for additional complex operations or large external force, greatly improving the convenience and efficiency of assembly.

[0053] Further, the locking mechanism 3 further comprises a limiting module 34 hinged to the base 1, the limiting module 34 and the hinge shaft of the base 1 are arranged in parallel, and the limiting module 34 and the hinge shaft of the base 1 are arranged in parallel, and the limiting module 34 is provided with a limiting swing rod 341, and the locking rotating wheel 33 is provided with a locking limiting groove 335 and an unlocking limiting groove 336. When the inner seat 2 is locked with the base 1, the limiting swing rod 341 cooperates with the locking limiting groove 335, and when the inner seat 2 is unlocked with the base 1, the limiting swing rod 341 cooperates with the unlocking limiting groove 336. The limiting swing rod 341 is perpendicular to the hinge shaft of the limiting module 34 and the base 1. When the inner seat 2 is unlocked with the base 1, the limiting swing rod 341 can accurately enter the unlocking limiting groove 336 to achieve stable cooperation. At this time, the limiting module 34 plays a good initial limiting role on the locking rotating wheel 33, which can prevent the locking rotating wheel 33 from rotating randomly due to slight external interference, ensure that the components of the locking mechanism 3 are in a stable initial position in the unlocked state, avoid unnecessary component displacement or damage, and lay a good foundation for subsequent connection and locking operation. An arc transition section is provided between the locking limiting groove 335 and the unlocking limiting groove 336 to ensure that the limiting swing rod 341 can smoothly transition between the locking limiting groove 335 and the unlocking limiting groove 336, while also considering the force balance and stability between the limiting module 34 and the locking rotating wheel 33 during state conversion. In actual assembly operation, when the inner seat 2 is placed in the mounting cavity 11 and connected with the base 1, as the locking rotating wheel 33 starts to rotate, the limiting swing rod 341 will naturally and smoothly move from the unlocking limiting groove 336 to the locking limiting groove 335 along the arc transition section, achieving cooperation between the two, without the need for additional large external force, greatly improving the convenience and efficiency of assembly operation.

[0054] Further, the locking mechanism 3 further comprises an elastic connecting piece 35, one end of which is connected with the locking rotating wheel 33, and the other end of which is connected with the limiting module 34. The limiting module 34 is provided with a reset swing rod 342, which is perpendicular to the limiting swing rod 341. The reset swing rod 342 and the locking rotating wheel 33 are respectively provided with through holes connected with the elastic connecting piece 35, which are firm and not easy to be loosened. The elastic connecting piece 35 can be a spring or a spring rope or other connecting piece with elastic energy storage function.

[0055] When the inner seat 2 is unlocked from the base 1, the limiting swing rod 341 cooperates with the unlocking limiting groove 336. Due to the connecting action of the elastic connecting piece 35, the locking rotating wheel 33 and the limiting module 34 are stably connected, and the two do not move relative to each other without other external force, further ensuring that the inner seat 2 and the base 1 remain in the unlocked state; when the inner seat 2 and the base 1 are locked, the locking rotating wheel 33 rotates, the elastic connecting piece 35 is stretched and stores elastic energy, and at the same time drives the limiting module 34 to rotate until the limiting module 34 rotates to the position where the limiting swing rod 341 cooperates with the locking limiting groove 335, thereby ensuring that the inner seat 2 and the base 1 remain in the locked state.

[0056] Further, the locking mechanism 3 further comprises a locking housing 36, which is fixedly connected with the base 1. The locking housing 36 is provided with a movable cavity, and the locking rotating wheel 33 is hingedly arranged in the movable cavity and can flexibly rotate around the hinge point. The locking housing 36 is provided with a counter interface 361 which is in communication with the movable cavity. When the inner seat 2 and the base 1 are locked, the unlocking force receiving part 334 is opposite to the counter interface 361, so that the user can observe and know the locking state of the inner seat 2 and the base 1; when the inner seat 2 and the base 1 are unlocked, the inner seat locking groove 332 on the locking rotating wheel 33 is opposite to the counter interface 361, so as to prepare for the next time the inner seat 2 is placed into the mounting cavity 11 and connected with the base 1.

[0057] In some embodiments, as shown in Figure 11 The inner seat 2 and the base 1 are provided with a plug-in mechanism 4, which comprises a plug-in block 41 and a plug-in groove 42 which cooperate with each other. The plug-in block 41 is arranged on one of the base 1 and the inner seat 2, and the plug-in groove 42 is arranged on the other one of the base 1 and the inner seat 2. The plug-in block 41 and the plug-in groove 42 have simple plug-in cooperation structure and are convenient to install.
