[0007] How to provide a baby stroller seat pocket rotating mechanism which can conveniently control the overall rotation of the seat.

[0008] The purpose of the present invention can be achieved by the following technical solutions:

[0009] A baby stroller seat pocket rotating mechanism comprises a rolling support assembly, a pushing assembly and a seat assembly, a rotating control assembly is arranged between the seat assembly and the rolling support assembly, the rotating control assembly comprises a first bevel gear, a second bevel gear, a first transmission gear, a second transmission gear, a transmission belt, an unlocking bevel wedge block, a seat pocket lock tongue and two push handle reversing lock tongues, the unlocking bevel wedge block is arranged below the pushing assembly, the transmission belt is connected between the first transmission gear and the second transmission gear, the two push handle reversing lock tongues are respectively arranged on both sides of the unlocking bevel wedge block, the unlocking bevel wedge block is connected to the rolling support assembly below through a first return spring, the seat pocket lock tongue is arranged between the seat assembly and the push handle reversing lock tongue, a second return spring is arranged inside the seat pocket lock tongue, and a clamping block is arranged at one end of the second return spring away from the push handle reversing lock tongue;

[0010] The first bevel gear is meshed with the second bevel gear, the first bevel gear is fixedly mounted on the bottom of the seat assembly, and the second bevel gear is fixedly connected to the second transmission gear;

[0011] The pushing assembly includes a support rod and a base, the bottom of the support rod is fixedly connected to the base, the first transmission gear is fixedly sleeved on the outer surface of the base, the bottom of the base is hinged to the rolling support assembly, the top of the support rod is movably sleeved with a connecting rod, and a pull rope is provided at one end of the connecting rod located inside the support rod, and the other end of the pull rope passes through the support rod and is connected to the unlocking inclined wedge block.

[0012] Furthermore, the seat assembly includes a seat cushion, a backrest and a U-shaped guardrail, the backrest is an arc-shaped plate with a bottom bent inward, the two ends of the U-shaped guardrail are respectively hinged on both sides of the front of the backrest, and a rubber sleeve is fixedly installed on the outer surface of the U-shaped guardrail.

[0013] Furthermore, the rolling support assembly includes a base, the top of the base is hinged to the bottom of the base, a first support rod is fixedly installed on the front side of the bottom of the base, a front leg plate is fixedly installed on the end of the first support rod away from the base, front wheels are arranged on both sides of the bottom of the front leg plate, and two symmetrical second support rods are fixedly installed on the rear side of the bottom of the base, and rear wheels are arranged on the bottoms of the two second support rods.

[0014] Furthermore, the connecting rod includes a pushing section, a connecting section and an unlocking section. The unlocking section is located inside the support rod, one end of the pull rope is fixed to the end face of the unlocking section, the pushing section is located outside the support rod, and a handle is fixedly installed on the end of the pushing section away from the support rod. The outer surface of the handle is fixedly sleeved with an anti-slip sleeve, and the outer surface of the connecting section is movably connected to the inner wall of the support rod.

[0015] Furthermore, the front wheel is vertically arranged below the front leg plate, the angle between the two second support rods is forty-five degrees, and the angle between the seat cushion and the backrest is one hundred and twenty degrees.

[0016] Furthermore, the method for using the baby stroller seat rotation mechanism comprises the following steps:

[0017] Step 1: Hold the handle with your hands and push the stroller forward. The front and rear wheels roll on the ground at the same time to drive the stroller forward.

[0018] Step 2: When the direction of the seat assembly needs to be adjusted, the pull rope is pulled through the connecting rod to separate the block of the seat pocket lock tongue from the bottom of the seat cushion. At this time, the handle is rotated to drive the seat to rotate, and the second bevel gear is driven to rotate under the transmission action of the first transmission gear, the transmission belt and the second transmission gear. At this time, the second bevel gear drives the first bevel gear to rotate so that the seat cushion and the backrest rotate at the same time, realizing the direction switching of the seat assembly;

[0019] Step 3: When the orientation of the seat assembly needs to be reset, loosen the pull rope, unlock the inclined wedge block to reset under the reaction force of the first reset spring, unlock the inclined wedge block to drive the seat pocket lock tongue to reset, push the block out under the reaction force of the second reset spring, and use the seat pocket lock tongue and the block to limit and fix the seat assembly.

[0021] The present invention has the following beneficial effects:

[0022] 1. The seat pocket can be quickly rotated and controlled by the provided rotation control assembly. The seat pocket lock tongue is separated from the bottom of the seat cushion by pulling the unlocking wedge block with a pull rope. After the seat cushion is unlocked, the seat cushion can be rotated and controlled by twisting the support rod. After the rotation is completed, the pull rope is released and the seat pocket lock tongue can be used to lock the seat cushion again by using the first return spring and the second return spring. The operation is simple and convenient.

[0023] 2. When pushing the baby stroller, the overall orientation of the seat assembly can be changed by controlling the overall rotation of the seat assembly, so that the seat assembly can face the side view when the baby stroller moves forward. The baby does not need to turn sideways or turn his head to view the scenery on both sides of the route. When the baby sits on the cushion, the overall orientation of the seat assembly is changed, and the baby can look directly at the side view, thus avoiding the baby turning sideways or turning his head for a long time to affect the normal development of his spine;

[0024] 3. When stopping to admire the scenery on both sides, the traditional baby stroller needs to adjust the direction of the whole vehicle. The parents hold the handle with their hands and gently press down to lift the front wheel, and then switch the direction of the whole vehicle through the rear wheel. The operation is too complicated. Compared with the prior art, the present application only needs to adjust the direction of the seat assembly when stopping to admire, and the steering operation of the seat assembly is completed by the cooperation of the pull rope and the support rod. At the same time, the pull rope and the support rod can switch the steering of the seat assembly while the parents stand in place during the operation. When the seat assembly turns, the rolling support assembly is also stationary. Therefore, during the steering process of the seat assembly, the space occupied by the parents and the entire baby stroller is small, and the convenience of outdoor use with people coming and going is further improved.
