[0033] Example
[0034] Cooperate Figures 1-6 As shown, for reference Figure 1 As shown, this utility model discloses a children's stroller, including a button device 1, a first axle mechanism 3, a rear leg 5, a second axle mechanism 7, a front leg 8, and a steel rope 11. The button device 1 is axially connected to the first axle mechanism 3 through the traction of the steel rope 11. The first axle mechanism 3 is axially connected to the second axle mechanism 7 through the traction of the steel rope 11. The front leg 8 is axially connected to the rear leg 5 through the second axle mechanism 7. The steel rope 11 can fold the stroller by connecting the first axle mechanism 3 and the second axle mechanism 7 in series.
[0035] Existing strollers have several drawbacks. When folded, the rear wheels are exposed on the outside of the frame, increasing space usage and making the stroller look loose and messy. Furthermore, the stroller needs to be held by hand after folding, otherwise it will have to be laid flat. When folding the stroller, the user needs to fold and press multiple joints and pins, which is sometimes difficult to do with both hands. The stroller requires two people to operate, which is cumbersome.
[0036] The button device 1 includes a button housing 1A, a spring core 1B, and a pull rope end 1C. The spring core 1B is fixed inside the button housing 1A. The spring core 1B and the pull rope end 1C are fitted with a clearance. The pull rope end 1C and the top of the steel rope 11 are an integral structure.
[0037] It should be noted that by manually applying pressure to the button housing 1A, the spring core 1B is activated, which pushes the pull rope end 1C to pull the steel rope 11. This allows the steel rope 11 to pull the first shaft mechanism 3 and the second shaft mechanism 7 out of the clamped engagement state, thus realizing the release action for easy vehicle retraction. The clamped engagement state is a shaft movement locking operation for unfolding the support vehicle, which achieves the convenience of one-step unlocking.
[0038] The first shaft mechanism 3 is provided with a shaft disc part 3A and a gear part 3B, the shaft disc part 3A is installed in the interior of the gear part 3B, the shaft disc part 3A is engaged with the gear part 3B and the shaft centers are collinear, and the frame of the shaft disc part 3A is fixed with one end of the steel rope 11.
[0039] It is necessary to explain that the shaft disc part 3A is driven to rotate by the traction of the steel rope 11, the driven gear part 3B is released from the clamping and fitting state, the gear part 3B is released from the clamping and fitting state, the gear part 3B is released from the clamping and fitting state, and the gear part 3B is released from the clamping and fitting state.
[0040] The second shaft mechanism 7 is provided with a joint gear 7A and a shell cover 7B, the joint gear 7A is installed in the interior of the shell cover 7B, the joint gear 7A is engaged with the shell cover 7B, and the inner ring frame of the joint gear 7A is fixed with one end of the steel rope 11.
[0041] It is necessary to explain that the shaft disc part 3A is driven to rotate by the traction of the steel rope 11, the driven gear part 3B is released from the clamping and fitting state, the gear part 3B is released from the clamping and fitting state, the gear part 3B is released from the clamping and fitting state, and the gear part 3B is released from the clamping and fitting state.
[0042] The button device 1 is provided with a car hand push frame 2 at the top, and the first shaft mechanism 3 is reversibly installed at the left and right lower corners of the car hand push frame 2.
[0043] It is necessary to explain that the button device 1 is pressed by artificial pressure, and the car hand push frame 2 and the first shaft mechanism 3 can realize the first step of folding operation.
[0044] The bottom of the first shaft mechanism 3 is provided with a hand handle frame 4 which can be reversibly folded, and the bottom of the hand handle frame 4 is provided with a second shaft mechanism 7 which can be reversibly folded.
[0045] It is necessary to explain that the hand handle frame 4 is inclined between the first shaft mechanism 3 and the second shaft mechanism 7, which is more convenient for step-by-step folding operation.
[0046] The bottom of the rear leg 5 is fixedly provided with a rear wheel 6, and the front leg 8 can be folded to the rear leg 5 through the second shaft mechanism 7.
[0047] It is necessary to explain that the folding operation of the front leg 8 to the rear leg 5 by the second shaft mechanism 7 allows the rear wheel 6 to be built-in between the front leg 8 and the rear leg 5, so as to reduce the folding volume and not occupy space, and the front leg 8 and the rear leg 5 can automatically stand after folding to support the whole vehicle body weight.
[0048] The left side of the handle frame 4 is respectively provided with a seat 9 and a handrail 10, the seat 9 is forwardly turned through a connecting rod and the second shaft mechanism 7, and the handrail 10 is forwardly turned through a connecting rod and the second shaft mechanism 7.
[0049] It should be noted that when the handle frame 2 is turned, the handle frame 4 and the second shaft mechanism 7 can realize the forward turning and folding of the seat 9 and the handrail 10 under the action of the connecting rod.
[0050] Working principle: the operator exerts force on the button shell 1A of the button device 1, and the spring core 1B pulls the rope end 1C and the steel wire 11 under the action of the slope of the handle frame 2; then the steel wire 11 pulls the shaft disc 3A of the first shaft mechanism 3 to rotate, and when the shaft disc 3A rotates, the shaft disc 3A will move axially under the action of the slope of the handle frame 2 and the handrail 4, thereby pushing the gear 3B to disengage, and when the gear 3B disengages, the handle frame 2 can be rotated and folded to realize the first step of folding the stroller, and at the same time, the seat 9 and the handrail 10 are turned forward under the action of the connecting rod of the handle frame 2 and the handrail 4.
[0051] It should be noted that by rotating the handle frame 4 and pulling the steel wire 11 at the same time, the joint gear 7A in the shell cover 7B of the second shaft mechanism 7 is pulled to rotate by the steel wire 11, and the joint gear 7A moves axially at the same time under the action of the slope of the handle frame 4, so as to achieve the operation of the steel wire 11 pushing the joint gear 7A to disengage; after the joint gear 7A disengages, the handle frame 4 automatically drives the front leg 8 to approach the rear leg 5 under the action of gravity, realizes the second step of folding the stroller, and the rear wheel 6 is stored between the front leg 8 and the rear leg 5, thereby achieving the effect of automatic folding of the stroller in two steps by pressing with one hand.
[0052] The button device 1 pulls the steel wire 11 by the spring core 1B to make the steel wire 11 pull the shaft disc 3A of the first shaft mechanism 3 to rotate axially to drive the gear 3B to disengage, so that the handle frame 2 can be turned and folded, and then the joint gear 7A of the second shaft mechanism 7 is pulled by the steel wire 11 in the handle frame 4 to rotate axially to disengage, so that the front leg 8 approaches the rear leg 5 and the rear wheel 6, the rear wheel 6 is hidden between the front leg 8 and the rear leg 5, and the stroller stands up, and finally the seat 9 and the handrail 10 are turned forward under the action of the connecting rod when the gear 3B disengages, thereby realizing the folding of the stroller with small volume; the rear wheel is hidden in the inside of the frame after folding, the overall feeling is strong after folding, the stroller stands up automatically after folding, and the handrail 10 can be folded when folding, and the folding can be realized by one hand.
[0053] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
