When in use, people apply a force to the baby stroller body, and the baby stroller body moves under the influence of the force. The existing baby stroller movement mode is relatively simple, and the most common one is smooth movement, which is conducive to the baby sitting or lying in the baby stroller to rest and sleep. However, when the baby is awake, the baby stroller that is pushed smoothly is relatively boring, and the baby is prone to crying. For this reason, a rocking baby stroller has appeared. During the pushing process, the baby stroller rises and falls while moving forward, forming a rocking baby stroller. For this baby stroller, it is still pushed by manpower, and there is also the problem of being relatively strenuous. Summary of the invention

DETAILED DESCRIPTION

[0025] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0026] Example: Figure 1-Figure 8 As shown, a sway control mechanism of an electric baby stroller includes wheels 2, a control seat 4, a driving mechanism cooperating with the control seat 4, and a sway control mechanism arranged on the control seat 4. The driving mechanism is a power driving mechanism for driving the wheels 2 to roll. The sway control mechanism cooperates with the driving mechanism to control the wheels 2 to roll smoothly or in a rocking manner.

[0027] In the present technical solution, the power supply is used to provide power for the driving mechanism, so that the driving mechanism becomes the power driving mechanism of the baby stroller, and the human drive is changed to electric drive. The wheel 2 is controlled to roll smoothly or rockingly by the swing regulating mechanism, so that the operation mode of the baby stroller is more diversified. When the infant needs to rest or sleep, it is adjusted to smooth pushing, which is beneficial to improving the rest and sleep quality of the infant. When the infant is awake and becomes irritable after sitting or lying in the baby stroller for a long time, it is adjusted to the rocking pushing mode, which is beneficial to improving the fun of using the baby stroller, making the infant more willing to lie in the baby stroller, reducing the intensity of adults raising infants and improving the physical and mental health of the caregivers.

[0028] In practical applications, in order to improve the shock absorption effect of the wheel 2, a damping spring 8 is arranged between the base frame 1 and the control seat 4. In order to facilitate the disassembly and assembly of the wheel 2, a wheel axle clamping mechanism 7 is arranged on the control seat 4, and a clamping groove is arranged at the clamping end of the wheel axle 6. The inner diameter variable clamp on the wheel axle clamping mechanism 7 cooperates with the clamping groove. When assembling the wheel 2, the wheel axle clamping mechanism 7 is manipulated to increase the inner diameter of the clamp, and the wheel axle 6 is inserted into the clamp, and the clamp is located at the clamping groove. The wheel axle clamping mechanism 7 is loosened, the clamp loses its force, the clamp is reset, the inner diameter becomes smaller, and the clamp is embedded in the clamping groove. At this time, the wheel 2 is matched with the control seat 4 through the wheel axle clamping mechanism 7, and the wheel axle 6 and the clamp can rotate. Conversely, the same operation can disassemble the wheel 2, which is conducive to reducing the occupied volume and facilitating packaging, storage, and transportation.

[0029] Next, we will explain the above technical issues in detail:

[0030] In actual application, the swing control mechanism includes a foot control 9 and a longitudinal swing mechanism arranged on the control seat 4. The foot control 9 includes a rotating shell 10 and a foot control outer lug 11 fixed on the rotating shell 10. The rotating shell 10 cooperates with the longitudinal swing mechanism to control the operation of the longitudinal swing mechanism by rotating the rotating shell 10 by stepping on the foot control outer lug 11, and releasing the foot control outer lug 11 to reverse and reset the rotating shell 10, thereby achieving the purpose of regulating the wheel 2 to roll smoothly or roll like a rocking car.

[0031] In actual application, the driving mechanism includes a power supply, a hub motor 5 that cooperates with the swing control mechanism and the power supply, the hub motor 5 is arranged on the hub of the wheel 2, and the axle 6 of the wheel 2 passes through the hub motor 5 and cooperates with the control seat 4.

[0032] In actual application, the longitudinal swing mechanism includes a swing seat 20, a return spring 21, a linkage shaft 25 arranged on the control seat 4, a limiting arc-shaped groove 28 arranged on the control seat 4, and a protrusion arranged on the inner wall of the rotating shell 10; the outer end of the linkage shaft 25 is fixed on the swing seat 20, and the inner end passes through the limiting arc-shaped groove 28 to cooperate with the wheel hub motor 5, and the end face of the swing seat 20 facing the inner wall of the rotating shell 10 is a concave-convex wedge surface 26, and the protrusion cooperates with the concave-convex wedge surface 26 to drive the linkage shaft 25 to cooperate with or separate from the wheel hub motor 5; when the linkage shaft 25 cooperates with the wheel hub motor 5, the linkage shaft 25 swings back and forth in the limiting arc-shaped groove 28 to drive the wheel hub motor 5 and the wheel 2 to swing longitudinally, so that the wheel 2 can achieve rocking-type rolling; the return spring 21 is arranged between the swing seat 20 and the control seat 4.

[0033] In actual application, an assembly groove 29 is provided on the control seat 4, a pivot 30 is provided in the assembly groove, the swing seat 20, the return spring 21 and the linkage shaft 25 are arranged in the assembly groove, an axial hole 31 is provided in the swing seat 20, the pivot 30 is inserted into the axial hole 31, so that the swing seat 20 rotates around the pivot 30 as the axis, and a swing hole 32 is provided on the corresponding side wall of the hub motor 5, and the swing hole 32 cooperates with the corresponding end of the linkage shaft 25.

[0034] In this technical solution, positioning outward-turned ends 22 are set at both ends of the return spring 21, and a positioning plane 23 and a positioning groove 24 are set on the control seat 4. One positioning outward-turned end 22 abuts against the positioning plane 23, and the other positioning outward-turned end 22 is embedded in the positioning groove 24.

[0035] In actual application, the assembly groove is fan-shaped, the cross-sectional shape of the rocking seat 20 is adapted to the shape of the assembly groove, the limiting arc-shaped groove 28 is arc-shaped, the central angle of the limiting arc-shaped groove 28 is adapted to the central angle of the assembly groove, and the center of the limiting arc-shaped groove 28 is located on the axis of the pivot 30.

[0036] In the present technical solution, the central angles of the assembly groove and the central angles of the limiting arc-shaped through groove 28 are set to control the longitudinal fluctuation degree of the wheel 2, so as to facilitate the formation of baby strollers with various shaking amplitude specifications.

[0037] In practical applications, a plurality of swing holes 32 are provided on the corresponding side walls of the hub motor 5 . The plurality of swing holes 32 are long strip holes with arc-shaped transitions at both ends arranged along the radial direction. The swing holes 32 are centrally symmetrically distributed with the hub motor 5 as the symmetry center.

[0038] In this technical solution, a plurality of brake holes are arranged in the circumferential direction, so that the brake shaft can be inserted into the corresponding brake hole to realize brake control at any time by stepping on the foot control 9. The long strip hole is conducive to cooperating with the limit arc groove 28, so that the wheel 2 can complete the longitudinal undulation while rolling forward, realizing the rocking car mode movement.

[0039] In actual application, the concave-convex wedge surface 26 includes at least two convex surfaces 17 spaced apart from each other, and axially inclined inclined surfaces 16 respectively matched with each convex surface 17. The inclination direction of each inclined surface 16 is consistent. The adjacent convex surfaces 17 and the inclined surfaces 16 sandwiched between the convex surfaces 17 form a groove. When the protrusion cooperates with the convex surface 17, the linkage shaft 25 moves axially outward and separates from the hub motor 5. When the protrusion slides into the bottom of the groove along the inclined surface 16, the linkage shaft 25 moves axially inward and forms a linkage match with the hub motor 5.

[0040] In this technical solution, the shape of the concave-convex inclined wedge surface 26 is such that each time the foot control 9 is stepped on, the linkage shaft 25 can axially move to cooperate with the protrusion or the groove, achieving the purpose of one-step control, which is beneficial to simplifying the operation and improving the operation reliability.

[0041] In practical applications, the protrusions are at least two first protrusions 27 and a second protrusion 15 arranged radially. The two protrusions are arranged on the same straight line. The axial height of the first protrusion 27 located on the outer side in the radial direction is greater than the axial height of the second protrusion 15 located on the inner side in the radial direction. The inclination rate of the inclined surface 16 gradually decreases from the central direction to the outer edge direction, so that the first protrusion 27 and the second protrusion 15 are adapted to the corresponding parts of the inclined surface 16.

[0042] In this technical solution, the first protrusion 27 and the second protrusion 15 are provided to move the linkage shaft 25 in a direction away from the hub motor 5, that is, to separate the linkage shaft 25 from the hub motor 5, and the wheel 2 contacts in a swinging mode, and the wheel 2 enters a stable rolling state. When the linkage shaft 25 slides down from the first protrusion 27 or the second protrusion 15 and slides into the bottom of the groove along the inclined surface 16, the linkage shaft 25 smoothly advances towards the hub direction and is inserted into the swinging hole 32, so as to cause the hub motor 5 to generate a longitudinal undulating action while rotating, thereby driving the vehicle to roll in the rocking car mode.

[0043] In practical applications, there are two wheels 2. The two wheels 2 are connected by a base frame 1. The power supply on the drive mechanism is arranged on the base frame 1. Control seats 4, drive mechanisms and swing control mechanisms are provided on both wheels 2. A synchronous traction rope 12 is arranged between the two swing control mechanisms to make the two wheels 2 move synchronously.

[0044] In this technical solution, both ends of the synchronous traction rope 12 are respectively connected to the corresponding foot controls 9 on the two wheels 2. Both ends of the synchronous traction rope 12 have a forward traction end 13 and a reverse traction end 14. The forward traction end 13 and the reverse traction end 14 at the same end are respectively arranged on the forward rotation part and the reverse rotation part of the rotating shell 10.

[0045] In practical applications, in order to ensure the service life and synchronous traction performance of the synchronous traction rope 12, the synchronous traction rope 12 is made of a steel rope. When the foot steps on the outer convex ear 11 of the foot control to make the rotating shell 10 rotate forward, the forward traction end 13 acts as the rotating shell 10 rotates, for realizing the forward synchronous traction of the synchronous traction rope 12 (including triggering the braking mechanism to brake the hub motor 5 and triggering the longitudinal swing mechanism to realize the rocking car mode), and vice versa, realizing the reverse synchronous traction of the synchronous traction rope 12 (including contacting the braking mechanism to brake the hub motor 5 and releasing the longitudinal swing mechanism to realize the rocking car mode).

[0046] The wheels 2 involved in the technical solution are arranged in the rear direction of the baby stroller (i.e., the rear wheels, and the double rear wheels are adopted, which is conducive to improving the stability of the baby stroller). Each wheel 2 is driven by its own driving mechanism and swing control mechanism, which is conducive to improving the synchronization and stability of each wheel 2 when the baby stroller is pushed, and is conducive to improving the operation reliability. In the technical solution, in order to simplify the structure, an external control component (i.e., a foot control 9) is arranged on a group of control mechanisms, the foot control 9 is operated, and the two groups of control mechanisms are controlled to respond simultaneously through the synchronization mechanism, so that the two groups of driving mechanisms can perform the same action at the same time, and the purpose of synchronous action of the two wheels 2 is achieved.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. In the above embodiments, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
