Technical Field

[0001] The present invention relates to the technical field of baby carriages, and more specifically, it relates to a quick-release clutch mechanism for a baby carriage steering wheel. Background Art

[0002] A baby carriage is a toy vehicle that children can drive and sit on. Currently, the main types of children's electric vehicles on the market are as follows: cars, motorcycles, and engineering vehicles. The shapes of various baby carriages are basically similar to those of various motor vehicles.

[0003] The existing quick-install steering wheel of a baby carriage usually inserts the steering wheel through a hole into the end of the rotating shaft, then uses bolts to penetrate the steering wheel and the rotating shaft, and finally tightens and fixes the steering wheel and the rotating shaft with nuts. This installation method of the steering wheel is very troublesome and not convenient for quick disassembly and installation.

[0004] Therefore, there is an urgent need for a new technical solution to solve the above technical problems. Summary of the Invention

[0007] The present invention is further arranged as: an annular groove is formed on the circumferential surface of the rotating shaft, a clutch groove penetrating its upper and lower surfaces is formed on the positioning plate, the clutch groove includes a first through groove with a half-circle circumference, and a second through groove with a diameter larger than that of the first through groove; By driving the positioning plate to slide through the driving component, the wall of the first through groove is clamped into the annular groove to fixedly install the steering wheel. Driving the positioning plate to slide through the driving component separates the first through groove from the rotating shaft and makes the second through groove communicate with the through hole, then the steering wheel and the rotating shaft can be disassembled.

[0008] The present invention is further configured such that: the first driving member includes a push rod disposed at one end of the positioning plate and extending out of the outer wall of the connecting sleeve, a limiting rod is disposed at the other end of the positioning plate, a first spring is sleeved on the limiting rod, and two ends of the first spring are fixedly connected to one end of the positioning plate and the inner wall of the end of the connecting shell. Under the elastic force of the first spring, the first through groove is snapped into the annular groove.

[0009] The present invention is further configured such that: a clutch control assembly for controlling the clutch of the steering wheel and the rotating shaft is further disposed on the rotating shaft. The clutch control assembly includes a fixed sleeve sleeved and fixed on the rotating shaft. A limiting block is slidably connected along the vertical direction on one side of the fixed sleeve. A limiting groove for inserting the limiting block is formed at the bottom of the connecting sleeve. The clutch control assembly further includes a second driving member for driving the limiting block to move up and down.

[0010] The present invention is further configured such that: a guiding groove penetrating through the top of the fixed sleeve is formed on one side of the fixed sleeve. A connecting groove is formed at the bottom of the limiting block.

[0011] The present invention is further configured such that: the second driving member includes a driving sleeve sleeved and rotatably connected to the circumferential surface of the fixed sleeve. An abutting block is disposed on the outer surface of the limiting block. An inclined abutting strip is disposed on the inner surface of the driving sleeve, and the bottom of the abutting strip abuts against the top of the abutting block.

[0012] The present invention is further configured such that: both sides of the abutting block are inclined surfaces, so that a positioning angle is formed at the top thereof. Positioning grooves for inserting the positioning angles are formed on the lower surfaces at both ends of the abutting strip.

[0013] The present invention is further configured such that: a plurality of vertically disposed anti-slip strips are disposed on the outer surface of the driving sleeve.

[0014] The present invention has the following beneficial effects: 1. The driving assembly drives the positioning plate to slide so that the wall of the first through groove is snapped into the annular groove to fixedly install the steering wheel. The driving assembly drives the positioning plate to slide so that the first through groove is separated from the rotating shaft, and the second through groove communicates with the through hole, thereby enabling the disassembly of the steering wheel and the rotating shaft; 2. Under the elastic force of the second spring, the top end of the limiting block is pushed into the limiting groove to limit the horizontal direction of the steering wheel. At this time, the steering wheel can control the rotation of the rotating shaft. The second driving member drives the limiting block to slide downward, so that the limiting block is separated from the limiting groove, and the steering wheel can no longer control the rotating shaft, thereby facilitating the control of the clutch of the steering wheel and the rotating shaft.

Detailed description of the specific implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Among them, the same parts are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0019] As shown in the figure, a quick-release clutch mechanism for a baby stroller steering wheel includes a steering wheel 1, the steering wheel 1 includes a disk body 2 and a connecting sleeve 3 provided at the bottom of the disk body 2, the connecting sleeve 3 is detachably connected to a rotating shaft 4, and a positioning component for detachably connecting to the rotating shaft 4 is provided in the connecting sleeve 3; The positioning component includes a connecting shell 5, the connecting shell 5 is provided with a through hole 6 penetrating its upper and lower surfaces for the rotating shaft 4 to pass through, a positioning plate 7 detachably connected to the rotating shaft 4 is slidably connected in the connecting shell 5 along the horizontal direction, and a first driving member for driving the positioning plate 7 is further included, and the installation and disassembly of the positioning plate 7 and the rotating shaft 4 are controlled by the first driving member.

[0020] The rotating shaft 4 is provided with an annular groove 8 along its circumferential surface. The positioning plate 7 is provided with a clutch groove 9 penetrating its upper and lower surfaces. The clutch groove 9 includes a first through groove 10 that is half of a circumference, and also includes a second through groove 11 with a diameter larger than that of the first through groove 10. The diameter of the first through groove 10 is larger than the diameter of the annular groove 8 and smaller than the diameter of the rotating shaft 4, and the diameter of the second through groove 11 is equal to the diameter of the rotating shaft 4. By driving the positioning plate 7 to slide through the first driving member, the wall of the first through groove 10 is clamped into the annular groove 8 to limit and install the steering wheel 1. The first driving member drives the positioning plate 7 to slide so that the first through groove 10 is separated from the rotating shaft 4, and the second through groove 11 is communicated with the through hole 6, then the steering wheel 1 and the rotating shaft 4 can be disassembled.

[0021] The first driving member includes a push rod 12 arranged at one end of the positioning plate 7 and extending out of the outer wall of the connecting sleeve 3. A limiting rod 13 is arranged at the other end of the positioning plate 7. A first spring 14 is sleeved on the limiting rod 13. The two ends of the first spring 14 are fixedly connected to one end of the positioning plate 7 and the inner wall of the end of the connecting shell 5. Under the elastic force of the first spring 14, the first through groove 10 is clamped into the annular groove 8. When it is necessary to disassemble the steering wheel 1, by pressing the push rod 12, the first spring 14 is compressed, so that the annular groove 8 of the rotating shaft 4 is separated from the first through groove 10. Finally, the rotating shaft 4 is placed in the second through groove 11, and then the steering wheel 1 and the rotating shaft 4 can be separated.

[0022] A clutch control component for controlling the clutch of the steering wheel 1 and the rotating shaft 4 is further arranged on the rotating shaft 4. The clutch control component includes a fixed sleeve 15 sleeved and fixed on the rotating shaft 4. A limiting block 16 is slidably connected along the vertical direction on one side of the fixed sleeve 15. A limiting groove 17 for inserting the limiting block 16 is opened at the bottom of the connecting sleeve 3, and it also includes a second driving member for driving the limiting block 16 to move up and down.

[0023] A guiding groove penetrating the top of one side of the fixed sleeve 15 is opened. A connecting groove is opened at the bottom of the limiting block 16. A second spring 18 is arranged in the connecting groove. The two ends of the second spring 18 are fixedly connected to the inner wall of the top end of the connecting groove and the bottom of the guiding groove. Under the elastic force of the second spring 18, the top end of the limiting block 16 is pushed into the limiting groove 17 to play a limiting role in the horizontal direction of the steering wheel 1. At this time, the steering wheel 1 can control the rotation of the rotating shaft 4.

[0024] The second driving member includes a driving sleeve 19 sleeved on and rotatably connected to the circumferential surface of the fixed sleeve 15. An abutting block 20 is arranged on the outer surface of the limiting block 16, and an inclined abutting strip 21 is arranged on the inner surface of the driving sleeve 19. The bottom of the abutting strip 21 abuts against the top of the abutting block 20. By rotating the driving sleeve 19, the top of the abutting block 20 moves along the bottom of the abutting strip 21, thereby driving the limiting block 16 to slide downward, so that the limiting block 16 is separated from the limiting groove 17. At this time, the steering wheel 1 cannot control the rotation of the rotating shaft 4, so that a child sitting in the stroller cannot control the stroller to turn, ensuring the safety of using the stroller.

[0025] Both sides of the abutting block 20 are arranged in an inclined plane, so that a positioning angle 22 is formed at its top. Positioning grooves 23 for inserting the positioning angle 22 are formed in the lower surfaces of both ends of the abutting strip 21. When the driving sleeve 19 is rotated and located at both ends of the abutting strip 21, the positioning angle 22 is clamped into the corresponding positioning groove 23 to ensure the stability of the steering wheel 1 in two states.

[0026] A plurality of vertically arranged anti-slip strips 24 are arranged on the outer surface of the driving sleeve 19, which is convenient for rotating the driving sleeve 19.

[0027] An arc-shaped groove 25 is formed in the circumferential side wall of the driving sleeve 19 along its circumferential direction, and a limiting strip 26 slidably connected to the arc-shaped groove 25 is arranged on the circumferential inner wall of the driving sleeve 19 along its circumferential direction to limit the rotation angle of the driving sleeve 19. When the limiting strip 26 rotates to both ends of the arc-shaped groove 25, it corresponds to the positioning angle 22 being clamped into the two positioning grooves 23.

[0028] The specific embodiments are only explanations of the present invention, and they are not limitations of the present invention. Those skilled in the art can make modifications to the embodiments without creative contributions according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
