Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-8, the stroller with high protection performance shown in the figures includes a stroller frame 1 and two driving rods 2, the two driving rods 2 are both installed at the bottom end of the stroller frame 1, two ends of the two driving rods 2 are both fixed with inflation wheels 3, the inflation wheels 3 make the stroller more stable during pushing, and an overspeed protection device 4 for effectively reducing the speed and preventing accidents when the stroller is accidentally out of control is installed at the bottom end of the stroller frame 1.

The overspeed protection device 4 comprises a backing plate 5, wherein other articles can be placed on the backing plate 5, so that sundries can be conveniently placed when a baby is pushed, connecting plates 6 are fixed on two sides of the backing plate 5 and are fixed with the stroller frame 1 through the connecting plates 6, moving openings 7 are formed in positions, corresponding to the driving rods 2, of two ends of the backing plate 5, and speed reduction assemblies 8 are installed in the moving openings 7;

the speed reducing assembly 8 comprises a speed reducing plate 9, the speed reducing plate 9 is slidably inserted into the moving port 7, the width of the moving port 7 is slightly larger than the thickness of the speed reducing plate 9, the speed reducing plate 9 can move in the moving port 7 in a short distance, a resetting piece 10 is installed at the top of the speed reducing plate 9, a speed limiting column 11 is fixed on the outer side of the driving rod 2, a plurality of speed limiting teeth 12 are fixed on the outer side of the speed limiting column 11 at equal angles, the speed limiting teeth 12 form a semi-arc shape, a plurality of clamping teeth 13 meshed with the speed limiting teeth 12 are fixed on one side of the speed reducing plate 9, and a brake plate 14 is fixed at the bottom of the speed reducing plate;

the reset piece 10 comprises a fixed rod 15, the fixed rod 15 is fixed on the backing plate 5, the top end of the fixed rod 15 penetrates through a reset plate 16 in a sliding manner, one side of the reset plate 16 is fixed with two inserting columns 17, and the position of the speed reducing plate 9 corresponding to the inserting column 17 is provided with a sliding hole 18, one end of the inserting column 17 penetrates through the sliding hole 18 in a sliding way, a first limit plate 19 is fixed, the speed reducing plate 9 is connected with the inserted column 17 in a sliding way through a sliding hole 18, so as to reduce the friction force of the speed reducing plate 9 during horizontal sliding, a return spring 20 is sleeved outside the fixing rod 15, and both ends of the return spring 20 are respectively contacted with the backing plate 5 and the return plate 16, the elastic force is generated through the elastic deformation of the return spring 20, thereby pushing the return plate 16 to rise, driving the speed reduction plate 9 to move upwards and completing the return, a second limiting plate 21 is further fixed at the top end of the fixing rod 15, so that the reset plate 16 is prevented from being separated from the fixing rod 15 when the speed reduction plate 9 moves upwards;

an installation groove 22 is formed in one side, away from the latch 13, of the speed reducing plate 9, a plurality of adjusting pieces 23 are fixed in the installation groove 22, a supporting plate 24 is fixed at the bottom of the backing plate 5, one side of the supporting plate 24 is in contact with the adjusting pieces 23, and a sliding groove 28 is formed in one side of the supporting plate 24, so that the adjusting pieces 23 cannot be inclined when moving, and the speed reducing plate 9 cannot be inclined when moving up and down;

the adjusting part 23 comprises a telescopic rod 25 and a contact hemispherical cap 26, and is of a hemispherical structure, so that the friction force is reduced, the telescopic rod 25 is smoother when moving, one end of the telescopic rod 25 is fixed in the mounting groove 22, the other end of the telescopic rod is fixed with the contact hemispherical cap 26, and is in contact with the outer wall of the supporting plate 24 through the contact hemispherical cap 26, an adjusting spring 27 is sleeved on the outer side of the telescopic rod 25, two ends of the adjusting spring 27 are in contact with the inner wall of the contact hemispherical cap 26 and the inner wall of the mounting groove 22 respectively, elastic force is generated through elastic deformation of the adjusting spring 27, and therefore the latch 13 on the speed reducing plate 9 is pushed to be in extrusion engagement with the speed limiting teeth 12.

In addition, the surface of the backing plate 5 is fixed with a protective shell 29 at the position corresponding to the speed reducing assembly 8, so that the damage caused by the contact of an external object and parts in the speed reducing assembly 8 can be prevented, the damage caused by accidental touch of personnel can be avoided, and the use safety is improved.

Overspeed protection principle in this scheme: when a pusher accidentally falls while pushing the stroller outside, or accidentally loosens his hands while not grasping the handle on a downhill section, when the pushing personnel forget to hold the baby stroller, the baby stroller can automatically advance without control, when the speed of the baby carriage reaches a certain value, the high-speed running of the inflation wheel 3 drives the driving rod 2 to run rapidly, thereby leading the speed-limiting post 11 and the speed-limiting tooth 12 at the outer side to run fast, leading the speed-limiting tooth 12 to be meshed with the latch 13 to rotate, leading the latch 13 to push downwards, thereby driving the speed reducing plate 9 to move downwards, finally enabling the brake plate 14 at the bottom of the speed reducing plate 9 to be contacted with the ground, improving the friction force, and enabling the baby carriage to be decelerated to stop through the meshing and blocking of the speed limiting teeth 12 and the blocking teeth 13, thereby preventing the baby carriage from moving forward uncontrollably and colliding to the stump and the like to damage the baby in the baby carriage;

when the baby carriage does not run away and runs at an excessive speed, namely when the baby carriage is pushed normally, the rotation of the inflating wheel 3 drives the rotation of the speed limiting teeth 12, when the speed limiting teeth 12 are meshed with the clamping teeth 13, the speed limiting teeth 12 can push the clamping teeth 13 to move downwards, so that the speed reducing plate 9 moves downwards, but when a plurality of arc-shaped speed limiting teeth 12 rotate to the other side and are not meshed with the clamping teeth 13 any more, because of the absence of the object limiting clamping teeth 13, the speed reducing plate 9 moves upwards under the action of the elastic force of the reset spring 20 in the reset piece 10 to realize reset, when the speed limiting teeth 12 rotate to be meshed with the clamping teeth 13 again, the speed reducing plate 9 is driven to move downwards to circulate all the time, the personnel cannot be influenced to push the baby carriage at a low speed, the normal use is not influenced, but when the baby carriage is out of control or the speed is high, the rotating speed of the speed limiting teeth 12 is higher than the reset speed of the speed reducing plate 9, so that the speed reducing, the clamping teeth 13 are clamped with the speed limiting teeth 12 and continuously move downwards to finally realize speed reduction and parking, under the condition, the speed limiting teeth 12 are not meshed with the clamping teeth 13 to be contacted, at the moment, the speed limiting teeth 12 can push the speed reducing plate 9 to move outwards for a short distance, at the moment, under the elastic action of the adjusting spring 27, when the speed limiting teeth 12 rotate to the next state of being meshed with the clamping teeth 13, the speed reducing plate 9 is pushed to move towards the direction of the speed limiting teeth 12 to realize meshing and continuously rotate.
