Description

Technical Field

[0001] The present invention relates to a baby carriage, in particular to a synchronous reversing mechanism for a push rod and a seat pocket of a baby carriage frame. Background Art

[0002] The reversing function of a baby stroller is one of its important functions. Currently, the most common ones are divided into handle reversing and seat reversing.

[0003] Currently, reversing the seat pocket requires removing it from the stroller frame, reversing the position, and then reattaching it. This is not only inconvenient, but also practically impossible for single mothers.

[0004] The push handle can be turned around the horizontal axis at a certain angle, which is more convenient than the seat. There is no need to remove the seat. The push handle can be pushed to rotate around the horizontal axis at a certain angle to realize the push of the stroller in the opposite direction.

[0005] However, after the handle is reversed, parents need to go around to the back of the stroller to push it, and the direction of the stroller needs to be turned around, which is inconvenient to use, especially when passing through a narrow space such as a passage. It is very difficult for parents to go around to the front of the stroller after the handle is reversed. In addition, after the seat pocket is turned, the rotation direction of the front and rear wheels changes, and both the front and rear wheels need to be universal wheels. Therefore, the current handle reversal also has disadvantages in use.

[0006] Currently, there are baby strollers that use a rotating seat to achieve seat steering. However, the push rod of this type of baby stroller cannot rotate and steer synchronously with the seat, and the central rotation mechanism of the seat is relatively complex, which easily causes the seat to shake during the reversal process and is not stable. In order to improve the strength of the steering mechanism, metal parts are currently used, resulting in high cost of the baby stroller frame, difficult production, and cumbersome seat reversal operation. Summary of the Invention

[0007] In order to overcome the above-mentioned defects, the present invention provides a synchronous reversing mechanism for a baby stroller frame push rod and a seat pocket. The synchronous reversing mechanism for the baby stroller frame push rod and the seat pocket has a simple structure and can realize synchronous reversal of the stroller seat pocket and the push rod. The reversal is convenient and smooth, and there is no need to remove the seat pocket or for parents to take a detour. It can adapt to use in various environments.

[0010] As a further improvement of the present invention, the unlocking operating device includes a handle, a pull rope and a latch reset elastic member. The handle is installed on the outer wall of the push rod and can move within a set range. A hollow channel for the pull rope to pass through is formed on the inner side of the push rod. One end of the pull rope is connected to the handle, and the other end of the pull rope is connected to the locking pin. The movement of the handle can drive the pull rope to slide in the hollow channel and then pull the locking pin to slide along the eccentric socket. The latch reset elastic member can provide the locking pin with an elastic retaining force toward the eccentric socket and the positioning slot.

[0011] As a further improvement of the present invention, a radially extending pin guide sleeve is provided on the outer circumferential wall of the lower end of the push rod, and the positioning pin can be inserted into the pin guide sleeve by sliding a set distance. The pin reset elastic member is a spring inserted in the pin guide sleeve, one end of the spring is fixedly connected to the inner side wall of the pin guide sleeve, and the other end of the spring is tightly against the positioning pin.

[0033] Embodiment: A synchronous reversing mechanism of a baby stroller frame push rod and seat pocket 4, comprising a frame body 1, a fixed seat 2, a rotating seat 3, a seat pocket 4, a push rod 5 and an unlocking operating device, wherein the fixed seat 2 is fixedly mounted on the frame body 1, the rotating seat 3 is axially stopped and can be rotatable around a vertical rotation axis in the circumferential direction on the fixed seat 2, the seat pocket 4 can be fixedly mounted on the rotating seat 3, and the lower end of the push rod 5 can be rotatably mounted on the rotating seat 3 around a horizontal rotation axis 19 extending in the horizontal direction, the rotating seat 3 is provided with at least two first locking fasteners symmetrically arranged along its axis, and the fixed seat 2 is provided with at least one second locking fastener, and each first locking fastener on the rotating seat 3 can be fastened and fixedly connected with the second locking fastener on the fixed seat 2 as the rotating seat 3 rotates, and the unlocking operating device can drive the first locking fastener and the second locking fastener to disengage and separate.

[0034] When the seat 4 needs to be turned, it is only necessary to unlock and disengage the first locking fastener and the second locking fastener, then rotate the swivel seat 3 to rotate it 180 degrees around the vertical axis, and rotate the push rod 5 around the horizontal axis 19 to rotate the set angle. At this time, the seat 4 has made a 180-degree turn, and the push rod 5 is still tilted toward the parent. Lock the first locking fastener and the second locking fastener to continue pushing the stroller forward. There is no need to remove the seat 4 during the turning process, which is convenient for parents to turn the seat 4. The push rod 5 first rotates with the seat 4, and then reverses and resets to the side facing the parent. In this way, the seat 4 will not be interfered with by the push rod 5 when turning, and the parent does not need to go around to the opposite side of the stroller to push the push rod 5. It is easy to use, not limited by the size of the space, avoids the stroller turning around, and does not require universal wheels for the rear wheels.

[0035] The first locking fastener includes at least two eccentric sockets 6 and locking pins 7 that are symmetrically arranged along the axis of the rotating seat 3. The second locking fastener is a positioning slot 8 provided on the fixed seat 2. The eccentric sockets 6 on the rotating seat 3 can be connected with the positioning slots 8 on the fixed seat 2 as the rotating seat 3 rotates. The locking pin 7 can be slidably installed on the side wall of the lower end of the push rod 5. The locking pin 7 can be inserted into the eccentric sockets 6 and positioning slots 8 that are connected as the push rod 5 rotates to fix the rotating seat 3 and the fixed seat 2. The unlocking operation device can drive the locking pin 7 to slide to insert it into or exit each eccentric socket 6 and positioning slot 8.

[0036] When the cam 3 is in the unlocked position, the locking pin 7 is released and the locking pin 7 is re-inserted into the eccentric hole 6 and the positioning slot 8. The locking pin 7 is inserted into the eccentric hole 6 and the positioning slot 8 to achieve the fixed positioning of the rotating seat 3 and the fixed seat 2. The eccentric hole 6 is symmetrically arranged on the rotating seat 3 to achieve the eccentric hole 6 and the positioning slot 8 to be directly connected before and after the rotating seat 3 is turned, thereby achieving the fixed positioning of the rotating seat 3 and the fixed seat 2 when the seat pocket 4 is facing different directions.

[0037] The unlocking operating device includes a handle 11, a pull rope 12 and a latch reset elastic member 13. The handle 11 is installed on the outer wall of the push rod 5 and can move within a set range. A hollow channel for the pull rope 12 to pass through is formed on the inner side of the push rod 5. One end of the pull rope 12 is connected to the handle 11, and the other end of the pull rope 12 is connected to the locking pin 7. The movement of the handle 11 can drive the pull rope 12 to slide in the hollow channel and then pull the locking pin 7 to slide along the eccentric socket 6. The latch reset elastic member 13 can provide the locking pin 7 with an elastic retaining force toward the eccentric socket 6 and the positioning slot 8.

[0038] By operating the handle 11 on the push rod 5, and then pulling the pull rope 12, the pull rope 12 pulls the locking pin 7 to move and realize its exit from the eccentric socket 6 and the positioning slot 8. At this time, the rotating seat 3 and the push rod 5 can be rotated to realize the steering of the seat pocket 4 and the push rod 5. When the steering of the seat pocket 4 and the push rod 5 is completed, the locking pin 7 automatically aligns with the eccentric socket 6 and the positioning slot 8 on the other side. After the locking pin 7 loses the tension of the pull rope 12, it automatically inserts into the eccentric socket 6 and the positioning slot 8 for fixed positioning under the elastic force of the pin reset elastic member 13. At this time, the rotating seat 3 and the push rod 5 can be rotated to realize the steering of the seat pocket 4 and the push rod 5. The seat 3, the fixed seat 2 and the push rod 5 are fixedly connected to form an integral structure, and the two cannot rotate relative to each other. The handle 11 can slide on the side wall of the push rod 5, such as sliding up and down or left and right to achieve traction of the pull rope 12. When the handle 11 slides on the push rod 5, it is best to set a slide groove on the push rod 5 to achieve guidance and limitation of the sliding of the handle 11. In addition, the handle 11 can also be rotated on the push rod 5 to wrap around the pull rope 12 to achieve traction of the pull rope 12. These are technical solutions that can be easily thought of by technical personnel in this field based on this patent, and they all fall within the scope of protection of this patent.

[0039] A radially extending latch guide sleeve 14 is provided on the outer circumferential wall of the lower end of the push rod 5. The positioning latch is inserted into the latch guide sleeve 14 to slide a set distance. The latch reset elastic member 13 is a spring inserted into the latch guide sleeve 14. One end of the spring is fixedly connected to the inner wall of the latch guide sleeve 14, and the other end of the spring is tightly against the positioning latch. The latch guide sleeve 14 can guide and position the latch sliding, ensuring that the locking latch 7 can smoothly slide radially along the lower end of the push rod 5 to lock the rotating seat 3 and the fixed seat 2. In addition to sliding radially along the lower end of the push rod 5 to lock the rotating seat 3 and the fixed seat 2, the locking latch 7 can also slide axially along the push rod 5 or in other directions to lock and position the rotating seat 3 and the fixed seat 2.

[0040] A slideway 9 is provided in the rotating seat 3 , and both ends of the slideway 9 in the extending direction are respectively connected to the openings of different eccentric sockets 6 , and the locking pin 7 can slide in the slideway 9 and enter the different eccentric sockets 6 .

[0041] When the cam 5 is in the unlocked position, the locking pin 7 is released and the locking pin 7 is released, so that the cam 5 can be unlocked and the locking pin 7 is released. The cam 7 is a kind of cam which is fixed on the sprocket 2 and has a plurality of cams 24, 25 and 26. The cam 7 is a kind of cam which is fixed on the sprocket 2 and has a plurality of cams 26. The cam 7 is a kind of cam which is fixed on the sprocket 2 and has a plurality of cams 24. The cam 7 is a kind of cam which is fixed on the sprocket 2 and has a plurality of cams 26.

[0042] The slide 9 is an arcuate slide, and a horizontal contact surface 10 is formed in the middle of the slide 9 to match the end surface of the locking pin 7. The end of the locking pin 7 can be in close contact with the horizontal contact surface 10 when the locking pin 7 is in the vertical position. The arcuate slide 9 facilitates the smooth sliding of the locking pin 7. The horizontal contact surface 10 is formed in the middle of the arcuate slide 9. After unlocking the locking pin 7, the push rod 5 is rotated to the vertical position. At this time, the end of the locking pin 7 just contacts the horizontal contact surface 10 of the arcuate slide 9. At this time, the locking pin 7 and the horizontal contact surface 10 can maintain a stable vertical contact state, ensuring that the push rod 5 is always in the vertical state during the rotation of the seat 3. That is, the locking pin 7 always remains in a stable position out of the eccentric socket 6, avoiding affecting the normal reversing of the seat 4. After the reversing is completed, the push rod 5 in the vertical state can be returned. The push rod 5 of this structure is always in the vertical state during the reversing process of the seat 4, making it easy to return the seat 4 to the parent after the reversing is completed, facilitating the rotation operation of the push rod 5.

[0043] A bearing is provided between the fixed seat 2 and the rotating seat 3 to ensure that the rotating seat 3 rotates smoothly on the fixed seat 2.

[0044] The rotating base 3 includes a rotating lower cover 15 and a rotating upper cover 16. The rotating upper cover 16 is detachably fixed to the upper end surface of the rotating lower cover 15. The eccentric sockets 6 are provided on the rotating lower cover 15. The rotating lower cover 15 is also provided with push rod lower positioning grooves 17 connected to each eccentric socket 6. The rotating upper cover 16 is provided with push rod upper positioning grooves 18. The lower end of the push rod 5 is rotatably inserted into the cylindrical space formed by the push rod lower positioning grooves 17 and the push rod upper positioning grooves 18. The rotating base 3 is divided into the rotating upper cover 16 and the rotating lower cover 15 to facilitate the installation and positioning of the push rod 5.

[0045] The lower end of the push rod 5 forms a horizontal rotation axis 19 with a larger diameter in the middle than at its ends. A cylindrical space with a larger diameter in the middle than at its ends is formed within the rotating seat 3. The horizontal rotation axis 19 at the lower end of the push rod 5 is rotatably accommodated within the cylindrical space, and the stepped surfaces on both axial sides of the lower end of the push rod 5 abut against the stepped surfaces on both axial sides of the cylindrical space. This structure limits the axial position of the push rod 5 within the rotating seat 3, preventing axial slippage that could cause the locking pin 7 to misalign with the eccentric socket 6.

[0046] The seat pocket 4 can be fixedly mounted on the rotating base 3 as follows: a plug-in slide 20 is provided on the upper surface of the rotating base 3, and an elastic clip 21 that can elastically expand and contract in the height direction is provided on the bottom surface of the plug-in slide 20. The seat pocket 4 is provided with a slide rail that can be inserted into the plug-in slide 20, and the upper and lower side plates and left and right side walls of the slide rail are respectively stopped on the inner side walls of the plug-in slide 20. The bottom surface of the slide rail of the seat pocket 4 is provided with a slot, and the elastic clip 21 on the bottom surface of the plug-in slide 20 can be snapped into the slot on the bottom surface of the slide rail of the seat pocket 4 for positioning. This structure allows the seat pocket 4 to be fixedly connected to the rotating base 3 and can also be removed to replace a different seat pocket 4 or a hand basket, which is convenient to use and has good versatility.
