[ Detailed description ] of the invention
The invention is further described below with reference to the accompanying drawings:
As shown in fig. 1 to 6, a brake assembly of a stroller comprises a first brake seat 11 and a second brake seat 12 respectively arranged at the lower ends of two supporting legs 200, wherein the first brake seat 11 and the second brake seat 12 are connected with a wheel 100, the first brake seat 11 is connected with a rotating pedal 13 which can rotate relatively to the first brake seat after being stepped on by a foot and can drive a brake pin 10 to lock the wheel 100 when rotating, a first return spring 14 which can drive the rotating pedal 13 to rotate and reset is arranged between the rotating pedal 13 and the first brake seat 11, a rotating block 16 which is connected with the rotating pedal 13 through a transverse shaft 15 and can follow rotation when the rotating pedal 13 rotates is arranged in the second brake seat 12, a second return spring 17 which can drive the rotating block 16 to rotate and reset is arranged between the rotating block 16 and the second brake seat 12, and a driving component 18 which can keep the brake assembly in a brake state and can unlock the brake assembly after being stepped on by the foot is also arranged on the second brake seat 12. When the baby carriage needs to be braked, only the rotating pedal 13 is needed to be stepped on, and the brake pin 10 is driven to be clamped into the wheel 100 when the rotating pedal 13 rotates, so that the braking is realized. When the rotating pedal 13 rotates, the rotating pedal 13 drives the rotating block 16 in the second brake seat 12 to rotate through the transverse shaft 15, and at the moment, the first return spring 14 and the second return spring 17 are compressed. When the stroller needs to walk, the driving part 18 is stepped down by the sole or the toe, so that the rotating block 16 rotates and resets under the elasticity of the second reset spring 17, the rotating pedal 13 is driven to act by the transverse shaft 15, the first reset spring 14 also applies the thrust of reverse rotation to the rotating pedal 13, and once the rotating block 16 and the rotating pedal 13 rotate and reset, the brake pin 10 also withdraws from the wheel 100, so that the unlocking of the brake assembly is realized. Therefore, when the brake assembly is unlocked, the driver 18 is only needed to be stepped down, the operation is very convenient and quick, the labor is very saved, and the people do not need to worry about scraping or damaging shoes.
As shown in fig. 2 to 6, the driving part 18 includes an arc hole 181 provided on the rotating block 16 and extending along the circumferential direction of the rotating block 16, the rotating block 16 is further provided with a bar hole 182 communicating with the arc hole 181 and extending along the radial direction of the rotating block 16, the second brake seat 12 is connected with a pedal 183 capable of being stepped on, the pedal 183 is provided with a clamping post 184 capable of being clamped into the bar hole 182 and the arc hole 181, and a third spring 185 capable of keeping the clamping post 184 in the bar hole 182 is further provided between the pedal 183 and the second brake seat 182. When the brake assembly needs to be locked, the rotating pedal 13 drives the rotating block 16 to rotate through the transverse shaft 15, and when the rotating block 16 rotates, the clamping post 184 in the arc-shaped hole 181 moves into the bar-shaped hole 182 under the action of the third spring 185. Because the clamping post 184 is clamped into the strip-shaped hole 182, the rotating block 16 cannot rotate continuously, so that the braking state of the baby carriage is maintained. When the stroller needs to walk, the pedal 183 is stepped down by the foot, the clamping post 184 is withdrawn from the bar-shaped hole 182 and enters the arc-shaped hole 181, at this time, the clamping post 184 cannot limit the rotation of the rotating block 16, the second return spring 17 drives the rotating block 16 to rotate, and the clamping post 184 continues to slide into the arc-shaped hole 181, so that the braking state of the stroller is released. Therefore, the braking or braking unlocking of the baby carriage is completed through the action of stepping down by feet, the unlocking mode that the traditional baby carriage needs to lift the brake pedal upwards by the instep is changed, the operation is simpler, more convenient and quicker, and the shoe can not be damaged even if the sole is stressed.
As shown in fig. 3 and 4, the pedal 183 includes a hinge rod 1831 hinged to the second brake seat 12, the hinge rod 1831 is provided with an upward bending rod 1832, the bending rod 1832 is provided with a pedal 1833 exposed from the second brake seat 12, and the locking post 184 is provided with the hinge rod 1831 or the bending rod 1832.
As shown in fig. 2 and 3, the second brake seat 12 is provided with a spring groove 186, the bending rod 1832 is provided with a protrusion 187, the third spring 185 is disposed in the spring groove 186, and the upper end of the third spring 185 abuts against the protrusion 187.
As shown in fig. 2 and 3, the rotating pedal 13 is provided with a first concave arc-shaped groove 13a, the inner wall of the first brake seat 11 is provided with a first limit boss 11a capable of extending into the first arc-shaped groove 13a, and the first return spring 14 is arranged between the groove wall of the first arc-shaped groove 13a and the first limit boss 11 a; the rotating block 16 is provided with a second concave arc-shaped groove 16a, the inner wall of the second brake seat 12 is provided with a second limit boss 12a which can extend into the second arc-shaped groove 16a, and the second return spring 17 is arranged between the groove wall of the second arc-shaped groove 16a and the second limit boss 12 a.
As shown in fig. 5, the rotating pedal 13 is provided with a groove 13b with an inclined side wall, when the rotating pedal 13 rotates, the inclined side wall of the groove 13b pushes the brake pin 10 to move laterally and be clamped into a brake hole (not shown in the drawing) of the wheel 100, and the first brake seat 11 is also provided with a third return spring (not shown in the drawing) capable of pushing the brake pin 10 to move laterally and be withdrawn from the wheel 100. When the rotating pedal 13 pushes the brake pin 10 to be clamped into the wheel 100, the third return spring is compressed, and when the rotating pedal 13 rotates to return, the third return spring pushes the brake pin 10 to return to the original position, and the brake pin is withdrawn from the wheel 100 to be unlocked. Of course, the same groove with an inclined surface may be provided on the rotating block 16, so that the brake pin 10 is also provided in the second brake seat 12, and the rotating block 16 can push the brake pin in the second brake seat 12 to lock the wheels when rotating, so that both wheels can be locked.
