[0012] Further, a limiting slide groove is provided on the locking installation disk, and a limiting protrusion is provided on the locking driving part, and the limiting slide groove and the limiting protrusion are slidably connected, so that the locking driving part can move relative to the locking installation disk toward the matching part; The locking mounting plate is also provided with a locking surface.

DETAILED DESCRIPTION

[0018] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] like Figures 1 to 12 A child stroller with a rocking function as shown in the figure comprises a child stroller body 1, characterized in that: the child stroller body 1 comprises a bottom support frame 2, a seat assembly 3 for carrying a child, and a rear wheel assembly 4 located at one side of the bottom support frame 2, a transmission mechanism 5 and a rocking mechanism 6 are provided between the rear wheel assembly 4 and the seat assembly 3, the seat assembly 3 is connected to the bottom support frame 2 and the rocking mechanism 6 respectively, a telescopic push rod 9 for driving the rear wheel assembly 4 to rotate is provided on the bottom support frame 2, when the rear wheel assembly 4 rotates, the rear wheel assembly 4 can drive the rocking mechanism 6 to rotate through the transmission mechanism 5, so that the rocking mechanism 6 drives the seat assembly 3 to perform a rocking motion; The present invention provides a bottom support frame, a seat assembly, and a rear wheel assembly. A transmission mechanism and a rocking mechanism are provided between the seat assembly and the rear wheel assembly. The seat assembly is connected to the bottom support frame and the rocking mechanism respectively. When the rear wheel assembly rotates, the main body of the child stroller can move in the horizontal direction, and the rear wheel assembly can drive the rocking mechanism to rotate through the transmission mechanism. The rocking mechanism drives the seat assembly to rock in the horizontal and vertical directions, so that the main body of the child stroller is no longer limited to a simple function of moving in the horizontal direction, which is conducive to providing a more diverse play experience and effectively solves the problem that most existing child strollers rely on manual pushing to achieve the walking function in the horizontal direction, thereby meeting the needs of parents to take their children out when the children are young. However, as the children grow up, the single child stroller mode that moves in the horizontal direction appears monotonous and boring, and cannot provide the children with more experience and fun.

[0020] Specifically, the child stroller body 1 has two movement modes. The first is a single movement in the horizontal direction with a horizontal walking track. The second is that while moving in the horizontal direction, the seat component 3 for carrying the child can also swing back and forth in a wave-like shape. The user can use the switching component 7 to select the first movement mode or the second movement mode according to actual conditions.

[0021] Furthermore, the rear wheel assembly 4 includes a first rear wheel mechanism 41 and a second rear wheel mechanism 42, a driving shaft 421 is provided between the first rear wheel mechanism 41 and the second rear wheel mechanism 42, the second rear wheel mechanism 42 rotates synchronously with the driving shaft 421, and the first rear wheel mechanism 41 rotates relative to the driving shaft 421. When the user selects a single movement mode along the horizontal direction, the driving member 72 will not be connected to the transmission mechanism 5, so that when the first rear wheel mechanism 41 rotates, the first rear wheel mechanism 41 will not drive the transmission mechanism 5 to rotate, and the rocking mechanism 6 will not drive the seat assembly 3 to swing back and forth in a wave-like manner. 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 vehicle body 1 moves in a single horizontal direction, and the walking trajectory is horizontal.

[0022] Furthermore, when the user selects the second movement mode of the child stroller body 1, the locking mechanism 71 is pressed toward the direction close to the transmission mechanism 5. The locking mechanism 71 is connected to the driving member 72, so that the locking mechanism 71 drives the driving member 72 to move toward the direction close to the transmission mechanism 5. The driving member 72 is connected to the transmission mechanism 5. The first rear wheel mechanism 41 rotates to drive the driving member 72 to rotate. The driving member 72 rotates synchronously with the transmission mechanism 5. The transmission mechanism 5 drives the rocking mechanism 6 to rotate. The seat assembly 3 swings back and forth in a wave-like manner driven by the rocking mechanism 6. The first rear wheel mechanism 41 rotates relative to the drive shaft 421, and the second rear wheel mechanism 42 rotates synchronously with the drive shaft 421, so that the child stroller body 1 can also move in a single horizontal direction.

[0023] Optionally, in some embodiments, the transmission mechanism 5 includes a first synchronous wheel, a second synchronous wheel connected to the swing mechanism 6, and a synchronous rotation belt. The first synchronous wheel includes a first connecting part and a second connecting part. The first connecting part can be engaged with the driving member 72 so as to rotate synchronously with the driving member 72. The second connecting part and the first connecting part are integrally formed. When the first connecting part rotates, the second connecting part rotates synchronously with the first connecting part. The synchronous rotation belt is simultaneously sleeved on the outer side wall of the second connecting part and the second synchronous wheel. When the second connecting part rotates, under the action of the synchronous rotation belt, the second synchronous wheel rotates synchronously with the second connecting part.

[0024] Further, as a preferred embodiment of the present invention but not limitation, the transmission mechanism 5 includes a plurality of transmission gears, which are meshed with each other in sequence, wherein the transmission gear located at the end can be engaged with the driving member 72 , thereby obtaining power under the action of the driving member 72 .

[0025] Optionally, in some embodiments, the rocking mechanism 6 includes a first rotating shaft 62 connected to the transmission mechanism 5, and a rocking link connected to the seat assembly 3. The rocking link is arranged in an "L" shape, one end of the rocking link is connected to the first rotating shaft 62, and the other end of the rocking link is connected to 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 rocking link to rotate eccentrically, thereby driving the seat assembly 3 to rotate eccentrically, and the seat assembly 3 swings back and forth in a wave-like manner.

[0026] Furthermore, as a preferred embodiment of the present invention but not a limitation, the rocking mechanism 6 includes a first rotating shaft 62 connected to the transmission mechanism 5, and an eccentric wheel 61 connected to the first rotating shaft 62, the eccentric wheel 61 is movably connected to 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 eccentric wheel 61 to rotate eccentrically in a circular direction, thereby driving the seat assembly 3 to rotate eccentrically, and the seat assembly 3 realizes a wave-like back and forth swing.

[0027] Furthermore, a telescopic push rod 9 is provided on the bottom support frame 2 for the user to push the stroller body 1. The telescopic push rod 9 allows the user to freely adjust the height of the telescopic push rod 9 according to personal height and usage habits. In this way, the user can find the pushing height that suits him best and avoid bending over for a long time or over-stretching the arms, thereby reducing fatigue when pushing the stroller and improving the comfort of use.

[0028] Optionally, in some embodiments, the telescopic push rod 9 includes a first telescopic rod 91 fixedly connected to the bottom support frame 2, and a second telescopic rod 92. The second telescopic rod 92 can move relatively inside the first telescopic rod 91 to achieve height adjustment. The inner wall of the first telescopic rod 91 is provided with a first thread, and the outer wall of the second telescopic rod 92 is provided with a second thread matching the first thread. A fixing screw is also provided on the moving side of the second telescopic rod 92. When the second telescopic rod 92 is adjusted to a suitable position, it is locked and fixed using the fixing screw.

[0029] Furthermore, as a preferred embodiment of the present invention but not a limitation, the telescopic push rod 9 includes a first telescopic rod 91 fixedly connected to the bottom support frame 2, and a second telescopic rod 92 located inside the first telescopic rod. The first telescopic rod 91 is provided with a plurality of locking holes along the length extension direction, and a buckle that cooperates with the locking hole buckle is provided on the movable side of the second telescopic rod 92. The buckle and the locking hole buckle are connected so that the user can adjust the height of the telescopic push rod 9.

[0030] like Figures 1 to 12 The rear wheel assembly 4 shown includes a first rear wheel mechanism 41 connected to the bottom support frame 2, and a switching assembly 7 for switching the motion state of the baby stroller body 1 is provided on the first rear wheel mechanism 41. The switching assembly 7 includes a locking mechanism 71, a driving member 72 for connecting the locking mechanism 71 and the transmission mechanism 5, and an elastic reset mechanism 73. The driving member 72 moves closer to or away from the transmission mechanism 5 through the locking mechanism 71 to switch the motion state of the baby stroller body 1. Furthermore, by providing a switching assembly 7 on the first rear wheel mechanism 41, the user can use the switching assembly 7 to change the movement mode of the child stroller body. When the locking mechanism 71 drives the driving member 72 to move away from the transmission mechanism 5, the first rear wheel mechanism 41 cannot drive the rocking mechanism 6 to rotate through the transmission mechanism 5. At this time, the child stroller body 1 can only move in the horizontal direction; when the locking mechanism 71 drives the driving member 72 to approach the transmission mechanism 5, the first rear wheel mechanism 41 can drive the rocking mechanism 6 to rotate through the transmission mechanism 5. At this time, the child stroller body 1 can move in the horizontal direction while also swinging in the horizontal and vertical directions, so that the user can easily switch the movement mode of the child stroller body 1 according to actual needs, which is conducive to increasing the flexibility of equipment use.

[0031] like Figures 1 to 12The first rear wheel mechanism 41 shown includes a first rear wheel frame 411, the locking mechanism 71 includes a locking mounting plate 711 connected to the first rear wheel frame 411, and a locking driving portion 712 that can move relative to the locking mounting plate 711 and is connected to the driving member 72, the transmission mechanism 5 includes a first transmission gear 51, the first transmission gear 51 includes a matching portion 511 that matches the driving member 72, when the locking driving portion 712 moves relative to the locking mounting plate 711, the locking driving portion 712 drives the driving member 72 to approach or move away from the matching portion 511; The locking plate 711 is fixedly arranged on the first rear wheel frame 411, and the locking driving part 712 is installed on the first rear wheel frame 411 through the locking plate 711. The locking driving part 712 is connected to the driving member 72, and the matching part 511 is an adapting groove whose shape is matched with the driving member 72. The inner side wall of the first rear wheel frame 411 is also provided with a mounting groove which is matched with the driving member 72. Under normal circumstances, the driving member 72 is fitted in the mounting groove, and the driving member 72 will not be connected with the matching part 511, so that when the first rear wheel frame 411 rotates, the driving member 72 is driven to rotate, and the driving member 72 will not drive the first transmission gear 51 to rotate. The child stroller body 1 moves in a single horizontal direction, and the walking trajectory is horizontal. When the body 1 switches to the second movement mode, the locking drive part 712 is pressed toward the direction close to the first transmission gear 51, and the locking mounting plate 711 is fixedly arranged on the first rear wheel frame 411 and will not move relatively. The locking drive part 712 moves relative to the locking mounting plate 711 toward the direction close to the first transmission gear 51, and the locking drive part 712 thereby drives the driving member 72 to move toward the matching part 511. The driving member 72 is embedded in the matching part 511, and when the first rear wheel frame 411 rotates, it drives the driving member 72 to rotate synchronously, and the driving member 72 drives the first transmission gear 51 to rotate synchronously, so that the transmission mechanism 5 can drive the rocking mechanism 6 to rotate eccentrically. When the child stroller body 1 moves in the horizontal direction, the seat assembly 3 can also swing back and forth in a wave-like manner.

[0032] Optionally, the locking mounting plate 711 and the first rear wheel frame 411 may be connected by threaded connection, snap connection, lock connection or the like.

[0033] Optionally, the locking driving portion 712 is provided with a connecting column extending toward the driving member 72 , and the driving member 72 is provided with a connecting groove engaged with the connecting column, so that the locking driving portion 712 can drive the driving member 72 to move relative to each other.

[0034] Optionally, the outer wall of the driving member 72 includes a first plane and a first arc surface, and the first plane and the first arc surface are alternately arranged in the circumferential direction. The overall shape of the matching groove and the mounting groove are both adapted to the shape of the driving member 72. The first plane and the first arc surface are alternately arranged in the circumferential direction so that the driving member 72 can form a tighter fit with the mounting groove on the inner wall of the first rear wheel frame 411 and the matching groove on the mating part 511, which helps to prevent the driving member 72 from loosening or displacement during operation, thereby enhancing the connection stability of the entire driving system.

[0035] like Figures 1 to 12 The elastic reset mechanism 73 shown in the figure includes a support seat 731 arranged on the bottom support frame 2, an unlocking member 732 that can move relative to the first transmission gear 51, and a spring member 733 located between the unlocking member 732 and the support seat 731. The first transmission gear 51 includes a first gear body 512 located on one side of the matching portion 511. The unlocking member 732 includes a connecting protrusion 7321 extending toward the matching portion 511 and slidably connected to the matching portion 511 and the first gear body 512 respectively. When the locking driving portion 712 drives the driving member 72 to approach the matching portion 511, the ends of the driving member 72 and the connecting protrusion 7321 abut against each other. The unlocking member 732 is located between the first transmission gear 51 and the support seat 731, and the support seat 731 is fixedly arranged on the bottom support frame 2. The unlocking member 732 includes a connecting protrusion 7321 extending toward the matching portion 511 and penetrating the matching portion 511 and the first gear body 512 at the same time. The connecting protrusion 7321 is slidably connected to the matching portion 511 and the first gear body 512 at the same time. When the child vehicle body 1 is in the first motion mode, at this time, the driving member 72 and the matching portion 511 are separated, and the connecting protrusion 7321 penetrates the first gear body 512 and extends into the matching portion 511. When the user presses the locking driving portion 712, the locking driving portion 712 drives the driving member 72 to move toward the matching portion 511, and the driving member 72 is embedded in the matching portion. 511, so that the driving member 72 abuts against the end of the connecting protrusion 7321 located in the matching portion 511, and pushes the connecting protrusion 7321 to move in the direction away from the matching portion 511, and the unlocking member 732 moves in the direction away from the first gear body 512, and the unlocking member 732 squeezes 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, and the spring member 733 undergoes elastic deformation. When the user chooses to switch back to the first motion mode, the driving member 72 is separated from the matching portion 511, and the spring member 733 restores its elastic deformation, so that the spring member 733 pushes the unlocking member 732 to move in the direction close to the first gear body 512, and the connecting protrusion 7321 extends into the matching portion 511 to complete the reset.

[0036] Furthermore, the mating portion 511 is located on a side of the first transmission gear 51 close to the driving member 72, and the first gear body 512 is located on a side of the first transmission gear 51 close to the spring member 733. The first gear body 512 and the mating portion 511 are integrally formed. The integrally formed design eliminates errors in mating surface processing and assembly, thereby improving transmission accuracy. In addition, since the gap between components is reduced, energy loss is reduced, thereby improving transmission efficiency. Secondly, the integral molding allows the first gear body 512 and the mating portion 511 to be tightly combined to form an integral structure. This structure enhances the structural stiffness of the entire transmission gear, reduces deformation or vibration that may occur during transmission, and thereby improves transmission stability.

[0037] like Figures 1 to 12 The transmission mechanism 5 shown includes a third transmission gear 53, the seat assembly 3 includes a bearing plate 31 movably connected to the bottom support frame 2, and a seat mounting seat 32 connected to the bearing plate 31, the rocking mechanism 6 includes an eccentric wheel 61 slidably connected to the seat mounting seat 32, and a first rotating shaft 62 connected to the eccentric wheel 61 and rotating synchronously with the third transmission gear 53, and the eccentric wheel 61 drives the seat mounting seat 32 to rock under the action of the first rotating shaft 62; Specifically, the supporting plate 31 is installed on the seat mounting seat 32, the first rotating shaft 62 is connected to the third transmission gear 53, the eccentric wheel 61 is connected to the first rotating shaft 62, and the eccentric wheel 61 is slidingly connected to the seat mounting seat 32, the connection between the first rotating shaft 62 and the eccentric wheel 61 does not coincide with the center of the eccentric wheel 61, when the child vehicle body 1 selects the second motion mode, 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, and the third transmission gear 53 drives the first rotating shaft 62 to rotate synchronously, and the first rotating shaft 62 drives the eccentric wheel 61 to drive the seat mounting seat 32 to rotate eccentrically in a circumferential direction, so that the supporting plate 31 located on the seat mounting seat 32 can swing back and forth in a wave-like manner.

[0038] Furthermore, the rocking mechanism 6 is symmetrically arranged on both sides of the seat mounting base 32, and the first rotating shaft 62 is simultaneously connected to the eccentric wheels 61 on both sides of the seat mounting base 32. The connection between the first rotating shaft 62 and the two eccentric wheels 61 is located in the same straight line and does not coincide with the center of the eccentric wheel 61.

[0039] Optionally, the first rotating shaft 62 may be fixedly connected to the third transmission gear 53 by means of connecting members such as screws and latches; similarly, the first rotating shaft 62 may be fixedly connected to the eccentric wheel 61 by means of connecting members such as screws and latches.

[0040] like Figures 1 to 12The unlocking member 732 shown includes a limiting portion 7322 slidably connected to the first rotating shaft 62, a limiting block 73221 is provided on the limiting portion 7322, a limiting hole 531 is provided on the third transmission gear 53, and the limiting block 73221 can extend into the limiting hole 531 to limit the rotation of the third transmission gear 53; Specifically, when the user selects the first motion mode, the driving member 72 leaves the matching portion 511, and the spring member 733 restores its elastic deformation to push the unlocking member 732 to move toward the first transmission gear 51, and the connecting protrusion 7321 on the unlocking member 732 penetrates the first gear body 512 and extends into the matching portion 511. At the same time, the limiting portion 7322 on the unlocking member 732 also moves toward the third transmission gear 53, and the limiting block 73221 on the limiting portion 7322 is inserted into the limiting hole 531 on the third transmission gear 53, thereby jamming the third transmission gear 53 to prevent the third transmission gear 53 from accidentally rotating, thereby further ensuring the stability of the child stroller body 1 in the first motion mode.

[0041] Furthermore, when the limit block 73221 extends into the limit hole 531, it is helpful to form a physical locking mechanism, which effectively limits the rotation of the third transmission gear 53. This locking mechanism can prevent the transmission system from accidentally moving or rotating when rotation is not required, thereby enhancing the stability and safety of the transmission.

[0042] Furthermore, when wave-like swinging is not required, the limit block 73221 can lock the third transmission gear 53 to prevent accidental start-up due to misoperation or external interference, thereby improving the safety of the children's stroller.

[0043] like Figures 1 to 12 The transmission mechanism 5 shown in the figure further includes a second transmission gear 52 located between the third transmission gear 53 and the first gear body 512, and the second transmission gear 52 is meshed with the third transmission gear 53 and the first gear body 512 respectively; Furthermore, by setting the second transmission gear 52, the transmission mechanism 5 can achieve multi-stage transmission, so that after the power is transmitted from the driving member 72 to the first transmission gear 51, it can be further transmitted to the third transmission gear 53 through the second transmission gear 52, thereby increasing the flexibility and diversity of the transmission.

[0044] Furthermore, the multi-stage transmission helps to reduce the impact and vibration during the transmission process and improve the smoothness of the transmission. The addition of the second transmission gear 52 makes the power transmission smoother and reduces the noise and wear caused by unstable transmission.

[0045] Furthermore, by providing a second transmission gear 52, it can be ensured that the rotation directions of the first gear body 512 and the third transmission gear 53 remain consistent. If only two gears are directly meshed, the rotation directions will be opposite. By adding a second transmission gear 52 in the middle, this situation can be changed so that the rotation directions of the first gear body 512 and the third transmission gear 53 are the same, which is beneficial to improving the stability of the child car body 1 when it is swinging.

[0046] Optionally, the radii of the first gear body 512 , the second transmission gear 52 , and the third transmission gear 53 increase sequentially.

[0047] like Figures 1 to 12 The locking installation plate 711 is provided with a limiting groove 7111, and the locking driving portion 712 is provided with a limiting protrusion 7121. The limiting groove 7111 and the limiting protrusion 7121 are slidably connected, so that the locking driving portion 712 can move relative to the locking installation plate 711 toward the direction close to the matching portion 511; The locking mounting plate 711 is further provided with a locking surface 7112. When the locking driving portion 712 is close to the matching portion 511, the locking driving portion 712 can rotate along the circumferential direction so that the limiting protrusion 7121 and the locking surface 7112 abut against each other. Specifically, under normal circumstances, the locking drive part 712 is located on the surface of the locking mounting plate 711. When the user chooses to switch the motion mode of the stroller body 1, the locking drive part 712 is pressed toward the direction close to the first gear body 512. Under the action of the sliding connection between the limiting protrusion 7121 and the limiting slide groove 7111, the locking drive part 712 can drive the driving member 72 along a preset direction to approach the first transmission gear 51. After the driving member 72 is in a suitable position, the user can rotate the locking drive part 712 in a circular direction so that the limiting protrusion 7121 on the locking drive part 712 abuts against the locking surface 7112, thereby allowing the stroller body 1 to maintain the second motion mode.

[0048] Furthermore, the sliding connection design between the limiting groove 7111 and the limiting protrusion 7121 ensures the stability of the locking drive part 712 when it moves relative to the locking mounting plate 711. This sliding connection can limit the moving trajectory of the locking drive part 712 and prevent it from deviating from the predetermined path, thereby ensuring the stability and reliability of the transmission mechanism.

[0049] Furthermore, when the locking drive portion 712 is close to the mating portion 511, it can rotate in a circular direction so that the limiting protrusion 7121 abuts against the locking surface 7112, which is conducive to realizing the locking function of the switching mechanism and can ensure that the relative position between the locking drive portion 712 and the locking mounting disk 711 is locked when necessary to prevent them from accidentally separating or moving.

[0050] like Figures 1 to 12 The bottom support frame 2 shown is provided with a mounting housing 21 for mounting the unlocking member 732 and the transmission mechanism 5; Specifically, the setting of the mounting housing 21 provides a mounting space for the transmission mechanism 5 , and the transmission mechanism 5 can be stably mounted to the mounting housing 21 , thereby preventing the transmission mechanism 5 from being offset during daily use.

[0051] Furthermore, the mounting housing 21 integrates the unlocking member 732 and the transmission mechanism 5 together, so that the overall structure is more compact, which helps to reduce the dispersion of parts and components, so that the entire mechanism is more orderly and efficient.

[0052] Furthermore, the mounting housing 21 provides a unified mounting platform to make the installation process of the unlocking member 732 and the transmission mechanism 5 easier, and the staff can more easily install these components to the correct positions and ensure that the relative positions between them are correct.

[0053] Furthermore, the installation shell 21 protects the unlocking member 732 and the transmission mechanism 5. The installation shell 21 can prevent these components from being disturbed and damaged by the external environment, such as dust, moisture, vibration, etc., which is beneficial to extend the service life of the components and improve the reliability of the entire mechanism.

[0054] like Figures 1 to 12 The bottom support frame 2 shown in the figure is provided with a hinge shaft 22 extending in the direction of the seat mounting seat 32, and a hinge hole 311 hinged to the hinge shaft 22 is provided on a side of the bearing plate 31 away from the seat mounting seat 32; Specifically, when the supporting plate 31 follows the seat mounting base 32 to make a wave-like swinging motion, the setting of the hinge shaft 22 and the hinge hole 311 is conducive to ensuring that the supporting plate 31 can follow the seat mounting base 32 to make a swinging motion, providing support for the supporting plate 31 to make a swinging motion.

[0055] Furthermore, the connection between the hinge shaft 22 and the hinge hole 311 provides a stable support point, ensuring that the support plate 31 will not accidentally deviate or shake during the swinging process, which is beneficial to reducing the vibration caused by the swinging motion and improving the stability of the entire system.

[0056] The implementation method of Example 1 is as follows: A baby stroller with a rocking function comprises a baby stroller body 1, the baby stroller body 1 comprises a bottom support frame 2, a seat assembly 3 for carrying a child, and a rear wheel assembly 4 located at one side of the bottom support frame 2, a transmission mechanism 5 and a rocking mechanism 6 are arranged between the rear wheel assembly 4 and the seat assembly 3, a telescopic push rod 9 for driving the rear wheel assembly 4 to rotate is arranged on the bottom support frame 2, the rear wheel assembly 4 comprises a first rear wheel mechanism 41, the first rear wheel mechanism 41 comprises a first rear wheel frame 411, a switching assembly 7 for switching the motion state of the baby stroller body 1 is arranged on the first rear wheel mechanism 41, the switching assembly 7 comprises a locking mechanism 71, a driving member 72 and an elastic reset mechanism 73, The locking mechanism 71 includes a locking mounting plate 711 connected to the first rear wheel frame 411, and a locking driving part 712 that can move relative to the locking mounting plate 711 and is connected to the driving member 72. The transmission mechanism 5 includes a first transmission gear 51 and a third transmission gear 53. The elastic reset mechanism 73 includes a support seat 731 arranged on the bottom support frame 2, an unlocking member 732 that can move 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 includes an eccentric wheel 61 that is slidably connected to the seat assembly 3, and a first rotating shaft 62 that is connected to the eccentric wheel 61 and rotates synchronously with the third transmission gear 53.

[0057] When the user selects a single movement mode in the horizontal direction, the driving member 72 will not be connected to the first transmission gear 51, so that when the first rear wheel mechanism 41 rotates, the first rear wheel mechanism 41 will not drive the first transmission gear 51 to rotate, and the rocking mechanism 6 will not drive the seat assembly 3 to swing back and forth in a wave-like manner. The first rear wheel mechanism 41 rotates relative to the drive shaft 421, and cooperates with the second rear wheel mechanism 42 to rotate synchronously with the drive shaft 421, so that the child vehicle body 1 moves only in the horizontal direction, and the walking trajectory is horizontal.

[0058] When the user selects the second movement mode, the locking driving portion 712 is pressed toward the direction close to the first transmission gear 51, and the locking driving portion 712 drives the driving member 72 to move toward the direction close to the first transmission gear 51, and the driving member 72 is embedded in the first transmission gear 51, and the driving member 72 pushes out the unlocking member 732, the spring member 733 is elastically deformed, and the unlocking member 732 moves toward the direction close to the support seat 731, and the limiting block 73221 on the unlocking member 732 disengages from the limiting hole 531 on the third transmission gear 53. At this time, the locking driving portion 712 is rotated in the circumferential direction so that the limiting protrusion 7121 on the locking driving portion 712 is aligned with the locking mounting plate 71 1 abuts against the locking surface 7112 on the locking drive portion 712, thereby maintaining the relative positions of the locking drive portion 712 and the locking mounting plate 711. When the first rear wheel mechanism 41 rotates, the first rear wheel mechanism 41 drives the driving member 72 to rotate synchronously, the driving member 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 slidably 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 a circular direction, the seat assembly 3 is driven by the eccentric wheel 61 to swing back and forth in a wave-like manner, and at the same time, the child stroller body 1 can move linearly in the horizontal direction.

[0059] When the user chooses to switch back to the first motion mode from the second motion mode, the locking driving part 712 is rotated in the circumferential direction, the limiting protrusion 7121 moves back into the limiting slide groove 7111, and the locking driving part 712 moves away from the first transmission gear 51, thereby driving the driving member 72 to separate from the first transmission gear 51, and the spring member 733 restores its elastic deformation. The unlocking member 732 moves toward the first transmission gear 51 under the action of the spring member 733, and the connecting protrusion 7321 on the unlocking member 732 extends into the inside of the first transmission gear 51, and the limiting block 73221 on the unlocking member 732 is inserted into the limiting hole 531 on the third transmission gear 53 to prevent the third transmission gear 53 from rotating accidentally. At this time, the child stroller body 1 can only move in the horizontal direction.

[0060] The implementation method of Example 2 is as follows: The difference between Example 2 and Example 1 is that the transmission mechanism 5 includes a first synchronous wheel, a second synchronous wheel connected to the swing mechanism 6, and a synchronous rotation belt. The first synchronous wheel includes a first connecting part and a second connecting part. The first connecting part can be engaged with the driving member 72 so as to rotate synchronously with the driving member 72. The second connecting part and the first connecting part are integrally formed. When the first connecting part rotates, the second connecting part rotates synchronously with the first connecting part. The synchronous rotation belt is simultaneously mounted on the second connecting part and the outer side wall of the second synchronous wheel. When the second connecting part rotates, under the action of the synchronous rotation belt, the second synchronous wheel rotates synchronously with the second connecting part.

[0061] The implementation method of Example 3 is as follows: The difference between Example 3 and Example 1 is that the rocking mechanism 6 includes a first rotating shaft 62 connected to the transmission mechanism 5, and a rocking link connected to the seat assembly 3. The rocking link is arranged in an "L" shape, with one end of the rocking link connected to the first rotating shaft 62, and the other end of the rocking link connected to 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 rocking link to rotate eccentrically, thereby driving the seat assembly 3 to rotate eccentrically, and the seat assembly 3 realizes a wave-like back and forth swing.

[0062] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but it does not mean that the implementation of the present invention is limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention shall be subject to the claims.
