Description

Technical Field

[0001] The invention relates to the technical field of maternal and infant appliances, in particular to a child stroller. Background Art

[0002] A stroller is a commonly used maternal and child equipment. It is a device used to accompany children as they grow and move around. It is convenient for adults to push the stroller and take the baby outdoors, and the children can sit comfortably and safely in the stroller. The stroller also has a sunshade. The overall frame and supporting rods of the stroller can be telescopically adjusted, so that the stroller itself can be folded and carried.

[0003] The existing child strollers are relatively large in size when folded. When folded, the rear wheels are exposed on the outside of the frame, which increases the occupied space. When the stroller is folded, the exposed rear wheels make it loose and messy, which makes the overall feeling poor. Moreover, when the stroller is folded, the stroller body needs to be held by hand or it needs to be fallen down and spread out. When folding the stroller, the user needs to fold multiple joints of the stroller body and press pins and bumpers. Sometimes it is not easy to fold and fold with both hands, and the operation requires the cooperation of two people, which is cumbersome. Summary of the invention

[0004] The present invention aims to provide a child stroller to solve the problems that the existing child strollers have a large folded volume; after the stroller is folded, the rear wheels are exposed outside the stroller frame, which increases the occupied space, and the stroller is loose and messy after being folded, resulting in a poor overall feeling due to the exposed rear wheels; and after the stroller is folded, the stroller body needs to be held by hand or it needs to be fallen down and spread out. When folding the stroller, the user needs to fold multiple stroller body joints and press latches and bumpers, and sometimes it is not easy to fold and fold with both hands, and the operation requires the cooperation of two people, which is cumbersome.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A child stroller comprises a button device, a first axis mechanism, a rear leg, a second axis mechanism, a front leg and a steel rope, wherein the button device is axially connected to the first axis mechanism by the traction of the steel rope, the first axis mechanism is axially connected to the second axis mechanism by the traction of the steel rope, the front leg is axially connected to the rear leg by the second axis mechanism, and the steel rope pulls the first axis mechanism and the second axis mechanism in series to fold the stroller.

[0007] Preferably, the button device is provided with a button shell, a spring movement, and a pull rope end. The spring movement is fixed in the button shell. The spring movement and the pull rope end are clearance-fitted. The pull rope end and the top end of the steel rope are an integrated structure.

[0008] By manually applying pressure to the button shell, the spring movement is pressed to push the pull rope end to pull the steel rope, so that the steel rope pulls the first axis mechanism and the second axis mechanism to both be out of the clamping and engaging state, thereby achieving a disengagement action to facilitate vehicle folding. The clamping and engaging state belongs to the dynamic locking operation of the supporting axle, which realizes the convenience of one-step unlocking.

[0009] Preferably, the first shaft mechanism is provided with a shaft disc component and a gear component, the shaft disc component is installed inside the gear component, the shaft disc component is meshed with the gear component and the axes are colinear, and the frame of the shaft disc component is fixed together with one end of the steel rope.

[0010] Through the traction of the steel rope, the pulling shaft disc actively cooperates with the driven rotation of the gear part, which can be separated from the clamping and engaging state of the gear part, allowing the gear part to realize the disengagement action to facilitate the retrieval of the vehicle. The clamping and engaging state belongs to the dynamic locking operation of the supporting axle, which realizes the convenience of one-step unlocking.

[0011] Preferably, the second axis mechanism is provided with a joint gear and a shell cover, the joint gear is installed inside the shell cover, the joint gear and the shell cover are clearance-fitted, and the inner ring frame of the joint gear is fixed together with one end of the steel rope.

[0012] The joint gear can be axially flipped by pulling the steel rope to disengage the joint gear from its clamping state, allowing the joint gear to be disengaged for easy vehicle retrieval. The clamping state belongs to the dynamic locking operation of the supporting axle, which realizes the convenience of one-step unlocking.

[0013] Preferably, a handlebar is mounted on the top of the button device, and first axis mechanisms are respectively mounted on the left and right lower corners of the handlebar so as to be flippable.

[0014] By manually applying pressure to the button device, the driver pushes the frame and the first axis mechanism to achieve the first step of folding and flipping the vehicle.

[0015] Preferably, a handle frame is mounted at the bottom of the first axis mechanism and can be turned over, and a second axis mechanism is mounted at the bottom of the handle frame and can be turned over.

[0016] With the help of the inclined surface of the handle frame between the first axis mechanism and the second axis mechanism, the integrated operation of step-by-step vehicle folding is more convenient.

[0017] Preferably, a rear wheel is fixedly provided at the bottom of the rear foot, and the front foot can be folded toward the rear foot via a second axis mechanism.

[0018] By folding the front foot towards the rear foot through the second-axis mechanism, the rear wheel can be built in between the front foot and the rear foot, reducing the folded volume so that the rear wheel does not take up space, and the front foot and the rear foot can automatically stand up to support the weight of the entire vehicle body after being folded.

[0019] Preferably, a seat and an armrest are respectively mounted on the left side of the handle frame; the seat can be flipped forward via a connecting rod and a second axis mechanism; and the armrest can be flipped forward via a connecting rod and a second axis mechanism.

[0020] When the rider pushes the frame to flip over, the handle frame combined with the second axis mechanism can realize the self-folding effect of flipping forward under the action of the connecting rod of the seat and the armrest.

[0021] After adopting the above technical solution, the present invention has the following advantages compared with the background technology:

[0022] 1. A child stroller of the present invention adopts a button device to pull the steel rope through the push and pull of the pull rope end of the spring movement, so that the steel rope pulls the shaft plate of the first shaft mechanism to axially rotate and drive the gear member to disengage, so that the rider can push the frame to flip and fold, and then pull the joint gear of the second shaft mechanism to axially rotate and disengage through the steel rope in the handle frame, so that the front foot moves closer to the rear foot and the rear wheel, so that the rear wheel is hidden between the front foot and the rear foot and the stroller stands, and finally the seat and the armrest flip forward under the action of the connecting rod when the gear member is disengaged, so that the folded volume of the child stroller is small; after the stroller is folded, the rear wheel is hidden inside the frame, and the overall feeling is strong after the stroller is folded; the stroller automatically stands after it is folded; when the stroller is folded, the armrest can be linked to be folded, and the folding and folding can be achieved with one hand.

[0033] Example

[0034] Cooperate Figure 1-Figure 6 As shown, reference Figure 1 As shown, the present invention discloses a child stroller, comprising a button device 1, a first axis mechanism 3, a rear leg 5, a second axis mechanism 7, a front leg 8, and a steel rope 11. The button device 1 is axially connected to the first axis mechanism 3 by the traction of the steel rope 11, the first axis mechanism 3 is axially connected to the second axis mechanism 7 by the traction of the steel rope 11, the front leg 8 is axially connected to the rear leg 5 by the second axis mechanism 7, and the steel rope 11 pulls the first axis mechanism 3 and the second axis mechanism 7 in series to fold the stroller.

[0035] The existing child strollers are relatively large in size when folded; the rear wheels are exposed outside the frame after the stroller is folded, which increases the occupied space, making the stroller look loose and messy after it is folded; and the stroller body needs to be held by hand after it is folded, or it needs to be fallen down and spread out. When folding the stroller, the user needs to fold multiple body joints and press pins and bumpers, and sometimes it is not easy to fold and fold with both hands, so it requires two people to cooperate in the cumbersome operation.

[0036] The button device 1 is provided with a button shell 1A, a spring movement 1B, and a pull rope end 1C. The spring movement 1B is fixedly arranged in the button shell 1A. The spring movement 1B and the pull rope end 1C are clearance-matched. The pull rope end 1C and the top end of the steel rope 11 are an integrated structure.

[0037] It should be noted that by manually applying pressure to the button shell 1A, the spring movement 1B is pressed to push the pull rope end 1C to pull the steel rope 11, so that the steel rope 11 pulls the first axis mechanism 3 and the second axis mechanism 7 to both be out of the clamping and engaging state, thereby realizing the disengagement action to facilitate the folding of the vehicle, and the clamping and engaging state belongs to the dynamic locking operation of the supporting axle, which realizes the convenience of one-step unlocking.

[0038] The first shaft mechanism 3 is provided with a shaft disc component 3A and a gear component 3B. The shaft disc component 3A is installed inside the gear component 3B. The shaft disc component 3A and the gear component 3B are meshed and their axes are colinear. The frame of the shaft disc component 3A is fixed to one end of the steel rope 11.

[0039] It should be noted that, through the traction of the steel rope 11, the pulling shaft disc part 3A actively cooperates with the driven rotation of the gear part 3B, and can be separated from the clamping and interlocking state of the gear part 3B, so that the gear part 3B can realize the disengagement action to facilitate the folding of the vehicle, and the clamping and interlocking state belongs to the dynamic locking operation of the supporting axle, which realizes the convenience of one-step unlocking.

[0040] The second shaft mechanism 7 is provided with a joint gear 7A and a shell cover 7B. The joint gear 7A is installed inside the shell cover 7B. The joint gear 7A and the shell cover 7B are clearance-fitted. The inner ring frame of the joint gear 7A is fixed to one end of the steel rope 11 .

[0041] It should be noted that the axial flipping of the joint gear 7A can be achieved by pulling the steel rope 11 to disengage the joint gear 7A from the clamping and engaging state, allowing the joint gear 7A to achieve a disengagement action for easy folding of the vehicle, and the clamping and engaging state belongs to the dynamic locking operation of the supporting axle, which realizes the convenience of one-step unlocking.

[0042] A handlebar frame 2 is mounted on the top of the button device 1 , and first shaft mechanisms 3 are mounted on the left and right lower corners of the handlebar frame 2 for rotation.

[0043] It should be noted that, by manually applying pressure to the button device 1, the driver pushes the frame 2 and the first axis mechanism 3 to achieve the first step of folding and flipping the vehicle.

[0044] A handle frame 4 is mounted at the bottom of the first shaft mechanism 3 and can be turned over. A second shaft mechanism 7 is mounted at the bottom of the handle frame 4 and can be turned over.

[0045] It should be noted that, due to the inclined surface of the handle frame 4 between the first shaft mechanism 3 and the second shaft mechanism 7, the integrated operation of step-by-step folding of the vehicle is more convenient.

[0046] A rear wheel 6 is fixedly disposed at the bottom of the rear leg 5 , and the front leg 8 can be folded close to the rear leg 5 via a second axis mechanism 7 .

[0047] It should be noted that, by the folding operation of the front leg 8 moving closer to the rear leg 5 through the second axis mechanism 7, the rear wheel 6 can be built in between the front leg 8 and the rear leg 5, the folded volume is reduced so that the rear wheel 6 does not occupy space, and the front leg 8 and the rear leg 5 can automatically stand up to support the weight of the entire vehicle body after the vehicle is folded.

[0048] A seat 9 and an armrest 10 are respectively mounted on the left side of the handle frame 4. The seat 9 can be flipped forward through a connecting rod and a second shaft mechanism 7, and the armrest 10 can be flipped forward through a connecting rod and a second shaft mechanism 7.

[0049] It should be noted that when the push frame 2 is flipped by the rider, the handle frame 4 combined with the second axis mechanism 7 can realize the self-folding effect of flipping forward under the action of the connecting rod of the seat 9 and the armrest 10.

[0050] Working principle: the operator applies force on the button shell 1A of the button device 1, and pulls the pull rope end 1C and the steel rope 11 through the spring movement 1B under the action of the inclined surface of the rider push frame 2; then the steel rope 11 pulls the shaft disc member 3A of the first shaft mechanism 3 to rotate, and when the shaft disc member 3A rotates, under the action of the inclined surfaces of the rider push frame 2 and the handle frame 4, the shaft disc member 3A will produce axial movement, thereby pushing the gear member 3B to disengage, and when the gear member 3B disengages, the rider push frame 2 can be rotated and folded to achieve the first step of folding the vehicle, and at the same time as the first step of folding the vehicle, the seat 9 and the armrest 10 are simultaneously flipped forward under the action of the connecting rod of the rider push frame 2 and the handle frame 4.

[0051] It should be noted that by rotating the handle frame 4 and pulling the steel rope 11 at the same time, the steel rope 11 pulls the joint gear 7A in the shell cover 7B of the second axis mechanism 7 to rotate, and simultaneously moves axially on the left and right sides of the inclined surface of the handle frame 4, so that the steel rope 11 pushes the joint gear 7A to disengage the engagement operation; after the joint gear 7A is engaged and disengaged, the handle frame 4 automatically drives the front foot 8 to move closer to the rear foot 5 under the action of gravity, realizing the second step of folding the vehicle, and the rear wheel 6 is stored between the front foot 8 and the rear foot 5 and stands upright, achieving the effect of automatically folding the vehicle in two steps by pressing with one hand.

[0052] The button device 1 is used to push and pull the pull rope end 1C through the spring movement 1B to pull the steel rope 11, so that the steel rope 11 pulls the shaft disc part 3A of the first shaft mechanism 3 to axially rotate and drive the gear part 3B to disengage, so that the push frame 2 can be flipped and folded, and then the joint gear 7A of the second shaft mechanism 7 is pulled by the steel rope 11 in the handle frame 4 to axially rotate and disengage, so that the front foot 8 is moved closer to the rear foot 5 and the rear wheel 6, so that the rear wheel 6 is hidden between the front foot 8 and the rear foot 5 and the stroller stands, and finally the seat 9 and the armrest 10 are flipped forward under the action of the connecting rod when the gear part 3B is disengaged, so that the folded volume of the child stroller is small; after the stroller is folded, the rear wheel is hidden inside the frame, and the overall sense is strong after the stroller is folded; the stroller automatically stands after it is folded; when the stroller is folded, the armrest 10 can be linked to be folded, and folding and folding can be achieved with one hand.

[0053] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
