The connecting protrusion 7321 is in sliding connection with the matching part 511 and the first gear body 512 at the same time. When the child stroller body 1 is in the first movement mode, at this time, the driving member 72 is separated from the matching part 511, and the connecting protrusion 7321 extends into the matching part 511 through the first gear body 512. When the user presses the locking driving part 712, the locking driving part 712 drives the driving member 72 to move towards the matching part 511, and the driving member 72 is embedded in the matching part 511, so that the driving member 72 abuts against the end of the connecting protrusion 7321 located in the matching part 511, and pushes the connecting protrusion 7321 to move away from the matching part 511. The unlocking member 732 moves away from the first gear body 512, and the unlocking member 732 presses the spring member 733. One end of the spring member 733 abuts against the unlocking member 732, and the other end of the spring member 733 abuts against the support seat 731. The spring member 733 is elastically deformed.

[0055] Further, the matching part 511 is located on the side of the first transmission gear 51 close to the driving member 72, the first gear body 512 is located on the side of the first transmission gear 51 close to the spring member 733, the first gear body 512 and the matching part 511 are integrally formed, the integrally formed design eliminates the matching surface processing and assembly error, thereby improving the transmission precision, in addition, since the gap between the parts is reduced, the energy loss is reduced, thereby improving the transmission efficiency; secondly, the integrally formed design makes the first gear body 512 and the matching part 511 tightly combined to form a whole structure, the structure enhances the structural rigidity of the whole transmission gear, reduces the deformation or vibration that may occur in the transmission process, thereby improving the stability of the transmission.

[0056] As shown in the transmission mechanism 5 shown in the Figures 1 to 12 The seat assembly 3 comprises a bearing plate 31 movably connected with the bottom support frame 2, and a seat mounting base 32 connected with the bearing plate 31, the swing mechanism 6 comprises an eccentric wheel 61 slidably connected with the seat mounting base 32, and a first rotating shaft 62 connected with the eccentric wheel 61 and synchronously rotating with the third transmission gear 53, the eccentric wheel 61 drives the seat mounting base 32 to swing under the action of the first rotating shaft 62;

[0057] Specifically, the bearing plate 31 is installed on the seat mounting base 32, the first rotating shaft 62 is connected with the third transmission gear 53, the eccentric wheel 61 is connected with the first rotating shaft 62, and the eccentric wheel 61 is slidably connected with the seat mounting base 32, the connection position of the first rotating shaft 62 and the eccentric wheel 61 does not coincide with the center of the eccentric wheel 61, when the second movement mode of the child car body 1 is selected, the driving member 2 and the first transmission gear 51 in the transmission mechanism 5 are connected, so that the third transmission gear 53 can rotate, the third transmission gear 53 drives the first rotating shaft 62 to synchronously rotate, the first rotating shaft 62 drives the eccentric wheel 61 to drive the seat mounting base 32 to eccentrically rotate in the circumferential direction, so that the bearing plate 31 located on the seat mounting base 32 can swing back and forth in a wave shape.

[0058] Further, the swing mechanism 6 is symmetrically arranged on both sides of the seat mounting base 32, the first rotating shaft 62 simultaneously connects the eccentric wheels 61 on both sides of the seat mounting base 32, the connection position of the first rotating shaft 62 and the two eccentric wheels 61 is located on the same straight line and does not coincide with the center of the eccentric wheel 61.

[0059] Optionally, the first rotating shaft 62 can be fixedly connected with the third transmission gear 53 through screws, bolts or other connecting members; similarly, the first rotating shaft 62 can be fixedly connected with the eccentric wheel 61 through screws, bolts or other connecting members.

[0060] As shown in the transmission mechanism 5 shown in the Figures 1 to 12The unlocking piece 732 shown includes a limiting part 7322 in sliding connection with the first rotating shaft 62, the limiting part 7322 is provided with a limiting block 73221, the third transmission gear 53 is provided with a limiting hole 531, the limiting block 73221 can extend into the limiting hole 531 to limit the rotation of the third transmission gear 53;

[0061] Specifically, when the user selects the first movement mode, the driving piece 72 moves away from the matching part 511, the spring piece 733 restores the elastic deformation to push the unlocking piece 732 to move towards the first transmission gear 51, the connecting protrusion 7321 on the unlocking piece 732 penetrates the first gear body 512 and extends into the matching part 511, at the same time, the limiting part 7322 on the unlocking piece 732 also moves towards the third transmission gear 53, the limiting block 73221 on the limiting part 7322 is inserted into the limiting hole 531 on the third transmission gear 53, thereby clamping the third transmission gear 53 to prevent the third transmission gear 53 from accidentally rotating, further ensuring the stability of the child car body 1 in the first movement mode.

[0062] Further, when the limiting block 73221 extends into the limiting hole 531, it is beneficial to form a physical locking mechanism, effectively limiting the rotation of the third transmission gear 53, which can prevent the transmission system from accidentally moving or rotating when it is not needed, thereby enhancing the stability and safety of the transmission.

[0063] Further, when the limiting block 73221 can lock the third transmission gear 53 when it is not needed to wave, it can prevent accidental start caused by misoperation or external interference, and improve the safety of the child car.

[0064] As Figures 1 to 12 The transmission mechanism 5 shown also includes a second transmission gear 52 between the third transmission gear 53 and the first gear body 512, the second transmission gear 52 is in engagement with the third transmission gear 53 and the first gear body 512 respectively;

[0065] Further, by setting the second transmission gear 52, the transmission mechanism 5 can realize multi-stage transmission, so that the power can be further transmitted to the third transmission gear 53 through the second transmission gear 52 after being transmitted from the driving piece 72 to the first transmission gear 51, thereby increasing the flexibility and diversity of the transmission.

[0066] Further, multi-stage transmission helps to reduce impact and vibration during transmission, improve the stability of transmission, and the addition of the second transmission gear 52 makes the power transmission smoother, reducing noise and wear caused by unstable transmission.

[0067] Further, by setting the second transmission gear 52, the rotating directions of the first gear body 512 and the third transmission gear 53 can be ensured to be consistent. If only two gears are directly engaged, the rotating directions will be opposite. By adding a second transmission gear 52 in the middle, the situation can be changed so that the rotating directions of the first gear body 512 and the third transmission gear 53 are the same, which is beneficial to improve the stability of the child car body 1 when swinging.

[0068] Optionally, the radii of the first gear body 512, the second transmission gear 52 and the third transmission gear 53 increase in turn.

[0069] As shown in the locking installation disc 711 is provided with a limiting sliding groove 7111, the locking driving part 712 is provided with a limiting protrusion 7121, the limiting sliding groove 7111 and the limiting protrusion 7121 are in sliding connection, so that the locking driving part 712 can move relative to the locking installation disc 711 towards the direction close to the matching part 511. Figures 1 to 12

[0070] The locking installation disc 711 is also provided with a locking surface 7112, when the locking driving part 712 is close to the matching part 511, the locking driving part 712 can rotate in the circumferential direction, so that the limiting protrusion 7121 and the locking surface 7112 abut.

[0071] Specifically, normally, the locking driving part 712 is located on the surface of the locking installation disc 711, when the user selects to switch the movement mode of the child car body 1, press the locking driving part 712 towards the direction close to the first gear body 512, under the action of the sliding connection between the limiting protrusion 7121 and the limiting sliding groove 7111, the locking driving part 712 can drive the driving part 72 to be close to the first transmission gear 51 in the preset direction, and after the driving part 72 is in the appropriate position, the user can rotate the locking driving part 712 in the circumferential direction, so that the limiting protrusion 7121 on the locking driving part 712 abuts on the locking surface 7112, so as to keep the child car body 1 in the second movement mode.

[0072] Further, the sliding connection design of the limiting sliding groove 7111 and the limiting protrusion 7121 ensures the stability of the locking driving part 712 when moving relative to the locking installation disc 711. This sliding connection can limit the movement track of the locking driving part 712 to prevent it from deviating from the predetermined path, thereby ensuring the stability and reliability of the transmission mechanism.

[0073] ​Furthermore, when the locking drive unit 712 approaches the mating part 511, it can rotate in the circumferential direction so that the limiting protrusion 7121 abuts against the locking surface 7112, which is beneficial to realize the locking function of the switching mechanism. It can ensure that the relative position between the locking drive unit 712 and the locking mounting plate 711 is locked when needed, preventing them from accidentally separating or moving.

[0074] like Figures 1 to 12 The bottom support frame 2 shown is provided with a mounting housing 21 for mounting the unlocking component 732 and the transmission mechanism 5;

[0075] Specifically, the mounting housing 21 provides mounting space for the transmission mechanism 5, enabling the transmission mechanism 5 to be stably mounted to the mounting housing 21 and preventing the transmission mechanism 5 from shifting during daily use.

[0076] Furthermore, the mounting housing 21 integrates the unlocking component 732 and the transmission mechanism 5 together, making the overall structure more compact and reducing the dispersion of parts, so that the entire mechanism is more orderly and efficient.

[0077] Furthermore, the mounting housing 21 provides a unified mounting platform to simplify the installation process of the unlocking component 732 and the transmission mechanism 5, allowing workers to more easily install these components in the correct positions and ensure that their relative positions are correct.

[0078] Furthermore, the mounting housing 21 protects the unlocking component 732 and the transmission mechanism 5. The mounting housing 21 can prevent these components from being disturbed or damaged by the external environment, such as dust, moisture, vibration, etc., which helps to extend the service life of the components and improve the reliability of the entire mechanism.

[0079] like Figures 1 to 12 The bottom support frame 2 shown is provided with a hinge shaft 22 extending toward the seat mounting base 32, and the bearing plate 31 is provided with a hinge hole 311 on the side away from the seat mounting base 32, which is hinged to the hinge shaft 22.

[0080] Specifically, when the support plate 31 follows the seat mounting base 32 in a wave-like swaying motion, the arrangement of the hinge shaft 22 and the hinge hole 311 helps to ensure that the support plate 31 can follow the seat mounting base 32 in a swaying motion, providing support for the swaying motion of the support plate 31.

[0081] Furthermore, the connection between the hinge shaft 22 and the hinge hole 311 provides a stable support point, ensuring that the bearing plate 31 will not accidentally shift or shake during the swinging process, which helps to reduce the vibration caused by the swinging motion and improve the stability of the entire system.

[0082] The embodiments of example 1 are as follows:

[0083] A child's vehicle with rocking function, comprising a child's vehicle body 1, the child's vehicle body 1 comprising a bottom support frame 2, a seat assembly 3 for carrying children, and a rear wheel assembly 4 located on one side of the bottom support frame 2, a transmission mechanism 5 and a rocking mechanism 6 being provided between the rear wheel assembly 4 and the seat assembly 3, the rear wheel assembly 4 comprising a first rear wheel mechanism 41, the first rear wheel mechanism 41 comprising a first rear wheel frame 411, a switching assembly 7 for switching the movement state of the child's vehicle body 1 being provided on the first rear wheel mechanism 41, the switching assembly 7 comprising a locking mechanism 71, a driving member 72, and an elastic reset mechanism 73, the locking mechanism 71 comprising a locking mounting disc 711 connected with the first rear wheel frame 411, and a locking driving part 712 movable relative to the locking mounting disc 711 and connected with the driving member 72, the transmission mechanism 5 comprising a first transmission gear 51 and a third transmission gear 53, the elastic reset mechanism 73 comprising a support seat 731 provided on the bottom support frame 2, an unlocking member 732 movable relative to the first transmission gear 51, and a spring member 733 located between the unlocking member 732 and the support seat 731, the rocking mechanism 6 comprising an eccentric wheel 61 in sliding connection with the seat assembly 3, and a first rotating shaft 62 connected with the eccentric wheel 61 and rotating synchronously with the third transmission gear 53.

[0084] When the user selects a single movement mode moving in the horizontal direction, the driving member 72 is not connected with the first transmission gear 51, so that when the first rear wheel mechanism 41 rotates, the first rear wheel mechanism 41 does not drive the first transmission gear 51 to rotate, and the rocking mechanism 6 does not drive the seat assembly 3 to swing forward and backward in a wave shape, the first rear wheel mechanism 41 rotates relative to the driving shaft 421, and cooperates with the second rear wheel mechanism 42 to rotate synchronously with the driving shaft 421, so that the child's vehicle body 1 moves in the horizontal direction only, and the walking track is in a horizontal shape.

[0085] When the user selects the second movement mode, the locking driving part 712 is pressed towards the first transmission gear 51, the locking driving part 712 drives the driving part 72 to move towards the first transmission gear 51, the driving part 72 is embedded in the first transmission gear 51, and the driving part 72 ejects the unlocking part 732, the spring part 733 is elastically deformed, the unlocking part 732 moves towards the support seat 731, the limiting block 73221 on the unlocking part 732 is separated from the limiting hole 531 on the third transmission gear 53, at this time, the locking driving part 712 is rotated in the circumferential direction, so that the limiting protrusion 7121 on the locking driving part 712 abuts against the locking surface 7112 on the locking mounting disc 711, thereby keeping the relative position of the locking driving part 712 and the locking mounting disc 711, when the first rear wheel mechanism 41 rotates, the first rear wheel mechanism 41 drives the driving part 72 to rotate synchronously, the driving part 72 drives the first transmission gear 51 to rotate synchronously, the third transmission gear 53 drives the first rotating shaft 62 to rotate synchronously, the eccentric wheel 61 and the seat assembly 3 are slidingly connected, and the seat assembly 3 and the bottom support frame 2 are hinged, so that when the first rotating shaft 62 drives the eccentric wheel 61 to rotate eccentrically in the circumferential direction, the seat assembly 3 swings back and forth in a wave shape under the driving of the eccentric wheel 61, and at the same time, the child car body 1 can move linearly in the horizontal direction.

[0086] When the user selects to switch back to the first movement mode from the second movement mode, the locking driving part 712 is rotated in the circumferential direction, the limiting protrusion 7121 moves back into the limiting sliding groove 7111, the locking driving part 712 moves away from the first transmission gear 51, thereby driving the driving part 72 to separate from the first transmission gear 51, the spring part 733 restores elastic deformation, the unlocking part 732 moves towards the first transmission gear 51 under the action of the spring part 733, the connecting protrusion 7321 on the unlocking part 732 extends into the first transmission gear 51, and the limiting block 73221 on the unlocking part 732 is inserted into the limiting hole 531 on the third transmission gear 53, preventing the third transmission gear 53 from accidentally rotating, at this time, the child car body 1 can only move in the horizontal direction.

[0087] The implementation of Example 2 is as follows:

[0088] The difference between Example 2 and Example 1 is that the transmission mechanism 5 includes a first synchronous wheel, a second synchronous wheel connected with the swing mechanism 6, and a synchronous rotating belt, the first synchronous wheel includes a first connecting part and a second connecting part, the first connecting part can be embedded with the driving part 72, thereby synchronously rotating with the driving part 72, the second connecting part is integrally formed with the first connecting part, and the second connecting part synchronously rotates with the first connecting part when the first connecting part rotates, the synchronous rotating belt is simultaneously sleeved on the outer side walls of the second connecting part and the second synchronous wheel, and the second synchronous wheel synchronously rotates with the second connecting part under the action of the synchronous rotating belt.

[0089] The embodiment of example 3 is as follows:

[0090] The difference between example 3 and example 1 is that the swing mechanism 6 comprises a first rotating shaft 62 connected with the transmission mechanism 5 and a swing connecting rod connected with the seat assembly 3, the swing connecting rod is arranged in an "L" shape, one end of the swing connecting rod is connected with the first rotating shaft 62, the other end of the swing connecting rod is connected with the seat assembly 3, when the first rotating shaft 62 rotates synchronously under the action of the transmission mechanism 5, the first rotating shaft 62 drives the swing connecting rod to rotate eccentrically, thereby driving the seat assembly 3 to rotate eccentrically, and the seat assembly 3 realizes the wave-shaped forward and backward swing.

[0091] The above is only to further illustrate the technical content of the utility model by examples, so that the reader can more easily understand, but it does not represent that the implementation mode of the utility model is limited to this, any technical extension or re-creation made according to the utility model is protected by the utility model. The protection scope of the utility model is subject to the claims.
