Description

Technical Field

[0001] The utility model relates to the technical field of wheel steering, in particular to a wheel steering control mechanism for a baby carriage. Background Art

[0002] The wheel steering control mechanism of a children's toy car is a sophisticated mechanical device used to change and control the direction of the toy car. In the design of modern children's toy cars, the steering system is one of the core technologies, which directly affects the handling performance of the toy car and the children's experience of using it. The control mechanism includes a power-assisting system, such as an electromagnetic induction unit, which can provide auxiliary force on the basis of manual control, making steering easier and smoother.

[0003] According to the Chinese patent with announcement number: CN215043410U, a baby stroller wheel steering control mechanism includes a rotating disk and a steering wheel for controlling the steering of the wheels. The steering wheel is freely rotatably connected to the rotating disk. The rotating disk and the steering wheel are also connected by a connecting piece so that the free rotation of the steering wheel can be transmitted to the rotating disk. The steering wheel is provided with a receiving and clamping structure. The connecting piece is slidably provided on the rotating disk and is provided with a locking structure that cooperates with the receiving and clamping structure. When the steering is manually controlled, the connecting piece slides on the rotating disk until the locking structure is engaged with the receiving and clamping structure, so that the steering wheel and the rotating disk rotate synchronously to control the steering of the baby stroller wheels.

[0004] In the above scheme, the connecting piece slides on the rotating wheel until the locking structure and the locking structure are engaged with each other, so that the steering wheel and the rotating wheel rotate synchronously. The above scheme still has the following disadvantages: when realizing the synchronous rotation of the steering wheel and the rotating wheel, if the connecting piece does not slide into place, the steering wheel and the rotating wheel may not rotate synchronously, causing the wheels of the baby carriage to lose control. Utility Model Content

[0005] The utility model aims to provide a baby carriage wheel steering control mechanism to solve the problem that when the steering wheel and the rotating wheel rotate synchronously, if the connecting piece does not slide into place, the steering wheel and the rotating wheel may not rotate synchronously, causing the baby carriage wheel to lose control.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a baby carriage wheel steering control mechanism, including an axle fixing member, a first slot is opened on the peripheral wall of the axle fixing member, a pivot is fixed inside the first slot, a clamping block is arranged on the lower side of the pivot, a button is fixed to the upper left end of the clamping block, the button passes through the first slot, and a first spring is fixed to the upper right end of the clamping block.

[0007] Preferably, the shaft fixing member is rotatably provided with a rotating disk, and an end of the rotating disk close to the shaft fixing member is provided with a receiving structure.

[0008] Preferably, a long guide groove is provided at one end of the shaft fixing member close to the rotating disk, and a connecting member is slidably provided in the long guide groove.

[0009] Preferably, a second slot is provided on the peripheral wall of the connecting member, a second spring is sleeved inside the guiding slot, one end of the second spring is fixed to one end of the connecting member, and the other end of the second spring is fixed to the inner wall of the guiding slot.

[0010] Preferably, the connecting member is provided with a locking structure, a transmission member is rotatably provided at one end of the shaft fixing member away from the rotating disk, a steering wheel is fixed to the transmission member, and the locking structure is slidably arranged with the locking structure.

[0011] Preferably, a sliding block is fixed on the peripheral wall of the connecting member, and a limiting groove is provided on the peripheral wall of the shaft fixing member, and the limiting groove and the sliding block are slidably arranged.

[0012] Compared with the prior art, a baby carriage wheel steering control mechanism adopting the above technical solution has the following beneficial effects:

[0013] 1. When the power-assist system of the wheel control mechanism of the baby stroller fails, the wheels of the baby stroller will rotate out of control because the steering wheel cannot be connected to the turning wheel. At this time, just press the button behind the steering wheel. The connecting piece that pops out of the shaft fixing piece can connect the steering wheel with the turning wheel, avoiding the need to manually slide the paddle to connect the shaft fixing piece with the steering wheel, thereby improving the convenience of switching from electric control to manual control;

[0014] 2. During the use of the baby stroller, when the electric control is switched to manual, the sliding card structure is locked to the sliding card structure to connect the shaft fixing part with the steering wheel. If the sliding card structure is rusted or aged, the sliding resistance is large for children. With the spring rebound force, when the wheel control of the baby stroller is switched from electric to manual, only the button needs to be pressed to prevent children from being unable to move the sliding paddle, thereby improving the stability of switching the wheel control from electric to manual and ensuring the safety of the user during use.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 4 As shown, a baby carriage wheel steering control mechanism comprises an axle fixing member 1, a first clamping groove 2 is provided on the peripheral wall of the axle fixing member 1, a pivot 3 is fixed inside the first clamping groove 2, a clamping block 4 is provided on the lower side of the pivot 3, a button 5 is fixed to the upper left end of the clamping block 4, the button 5 passes through the first clamping groove 2, a first spring 6 is fixed to the upper right end of the clamping block 4, a rotating disk 7 is rotatably provided on the axle fixing member 1, a receiving structure 8 is provided on one end of the rotating disk 7 close to the axle fixing member 1, a second clamping groove 11 is provided on the peripheral wall of the connecting member 10, a second spring 12 is sleeved inside the guide long groove 9, one end of the second spring 12 is fixed to one end of the connecting member 10, and the other end of the second spring 12 is fixed to the inner wall of the guide long groove 9, a sliding block 17 is fixed on the peripheral wall of the connecting member 10, a limiting groove 16 is provided on the peripheral wall of the axle fixing member 1, and the limiting groove 16 and the sliding block 17 are slidably arranged.

[0023] During the driving of the baby carriage, the electric steering control mode is adopted to effectively reduce the steering torque, which is convenient for the user to control the steering of the baby carriage. When the electromagnetic induction power-assisting unit fails, the user presses the button 5. The user presses the button 5 downward. At this time, the button 5 applies a downward force to one end of the block 4. Since the middle position of the block 4 and the pivot 3 are rotatably arranged, the other end of the block 4 is lifted upward. At this time, the other end of the block 4 will be separated from the first slot 2. At this time, the rebound force of the second spring 12 will push the connecting member 10 out of the guide slot 9. Since the limiting slot 16 slides to control the sliding block 17, the connecting member 10 connected to the sliding block 17 can only translate along the axial direction without offset. At the same time, it is ensured that the connecting member 10 will not separate or fall off from the shaft fixing member 1 during the movement, thereby improving the stability of the connecting member 10 during the extension process.

[0024] like Figure 1-Figure 5As shown, a guide long groove 9 is provided at one end of the shaft fixing member 1 close to the rotating disk 7, a connecting member 10 is slidably provided on the guide long groove 9, and a locking structure 15 is provided on the connecting member 10. A transmission member 13 is rotatably provided on the end of the shaft fixing member 1 away from the rotating disk 7, a steering wheel 14 is fixed to the transmission member 13, and the locking structure 15 is slidably provided with the supporting structure 8.

[0025] During use, the connecting member 10 enters the receiving structure 8 of the rotating disk 7 through the thrust of the first spring 6, so that the steering wheel 14 and the rotating disk 7 are connected, and the user can control the steering of the baby stroller wheels by manually controlling the steering wheel 14. When the power-assist system is repaired, the user pushes the sliding block 17 away from the steering wheel 14, and one end of the connecting member 10 applies a force to the second spring 12, and the second spring 12 is gradually compressed. The outer side of the second card slot 11 of the connecting member 10 squeezes one end of the card block 4. Since the middle position of the card block 4 and the pivot 3 are between the rotating The card block 4 is set to be dynamic, and the card block 4 will rotate around the pivot 3. The squeezed end of the card block 4 will be lifted upward, and the first spring 6 on the card block 4 is in a compressed state. When the card block 4 reaches the position of the second card slot 11, the card block 4 is no longer squeezed, and the resilience of the first spring 6 causes one end of the card block 4 to drop downward, and the right side of the card block 4 abuts against the right side of the second card slot 11, so that the connecting member 10 is not pushed by the resilience of the second spring 12. At this time, the connecting member 10 is hidden inside the shaft fixing member 1, and the steering wheel 14 cannot directly contact the rotating disk 7. The steering control of the baby stroller is completed by electric power.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
