Description

Technical Field

[0001] The utility model relates to the technical field of children's vehicles, in particular to a wheel assembly for a children's vehicle and the children's vehicle. Background Art

[0002] As a great tool for carrying children, strollers have become popular among consumers. Existing strollers are generally divided into two types: those with pedals and those without. Models with pedals are usually fixed to the front wheels of the stroller and are mainly used by the user to push or drive the stroller. Although fixed pedals for strollers have a simple structure and low manufacturing cost, their functions are relatively simple. In addition, pedals with this structure will still rotate with the wheels when the stroller is pushed. At this time, the feet of the child riding will still rotate with the rotation of the pedals, and thus the child will not be able to get enough rest. Utility Model Content

DETAILED DESCRIPTION

[0034] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0035] like Figures 1 to 10 As shown, in this solution, the specific structure of the wheel assembly and its application in a children's vehicle are mainly described in detail. The above-mentioned children's vehicle can be a children's two-wheeled vehicle or a children's three-wheeled vehicle.

[0036] A wheel assembly for a baby stroller includes a wheel body 100 , a pedal assembly 200 , a first clamping member 300 , and a second clamping member 400 .

[0037] The pedal assembly 200 is connected to the wheel body 100 and has a locked state and a free state. When the pedal assembly 200 is in the locked state, it is used to drive the wheel body 100 to rotate when the pedal assembly 200 rotates. When the pedal assembly 200 is in the free state, it is used to prevent the wheel body 100 from rotating when the pedal assembly 200 rotates; the first clamping member 300 is movably connected to the wheel body 100 and has a locked position and an unlocked position on the wheel body 100; the second clamping member 400 is movably connected to the wheel body 100 and is in a state with the first clamping member 300. Movable clamping; when the pedal assembly 200 is in a locked state, the first clamping member 300 is in a locked position, and the second clamping member 400 is disengaged from the first clamping member 300, so that the first clamping member 300 can move from the locked position to the unlocked position when subjected to force; when the pedal assembly 200 is in an unlocked state, the second clamping member 400 is in a clamping state with the first clamping member 300, so that the first clamping member 300 is fixed in the unlocked position, and when the second clamping member 400 is subjected to force and disengaged from the first clamping member 300, it is used to make the first clamping member 300 move from the unlocked position to the locked position.

[0038] Reference Figures 1 to 5 At this point, the first clamping member 300 is in the locked position, engaging the first clamping member 300 with the pedal assembly 200, and locking the pedal assembly 200. At this point, rotating the pedal assembly 200 can drive the wheel body 100, allowing a child to rotate the wheel body 100 normally using the pedal assembly 200. Furthermore, because the second clamping member 400 is not engaged with the first clamping member 300 at this point, the first clamping member 300 can move relative to the wheel body 100 when a force is applied.

[0039] When the first clamping member 300 is pushed, it moves from the locking position to Figures 6 to 9 In the unlocked position shown, the first engaging member 300 is disengaged from the pedal assembly 200, freeing the pedal assembly 200. Furthermore, the second engaging member 400 is engaged with the first engaging member 300, securing the first engaging member 300 in the unlocked position. In this position, rotating the pedal assembly 200 does not rotate the wheel body 100. Similarly, rotating the wheel body 100 does not rotate the pedal assembly 200. In this position, when pushing the stroller and placing a child's foot on the pedal assembly 200, the child's foot will not be moved by the rotation of the pedal assembly 200, allowing the child to rest adequately.

[0040] When the first clamping member 300 is in the unlocked position, the pedal assembly 200 is in a free state and the second clamping member 400 is forced to move relative to the wheel body 100, so that the second clamping member 400 and the first clamping member 300 are disengaged from the clamped state, the first clamping member 300 moves from the unlocked position to the locked position, so that the pedal assembly 200 is in a locked state. Then, when the pedal assembly 200 is rotated, the wheel body 100 can be driven to rotate, so that the child can normally drive the wheel body 100 to rotate.

[0041] In this solution, a first clamping member 300 is movably provided on the wheel body 100, and a second clamping member 400 movably engaged with the first clamping member 300 is provided. When the first clamping member 300 is in the locked position, force is applied to the first clamping member 300 to move it to the unlocked position, thereby completing the transition of the pedal assembly 200 from the locked state to the free state. Therefore, when the stroller is pushed and the child's feet are placed on the pedal assembly 200, the child's feet will not move due to the rotation of the pedal assembly 200, thereby allowing the child to get sufficient rest. When the first clamping member 300 is in the unlocked position, force is applied to the second clamping member 400 to move the first clamping member 300 to the locked position, thereby completing the transition of the pedal assembly 200 from the free state to the locked state.

[0042] In one embodiment, the first clamping member 300 is movably connected to the wheel body 100 and has a first moving direction and a second moving direction in opposite directions; when the second clamping member 400 is subjected to force to disengage from the first clamping member 300, the first clamping member 300 moves along the first moving direction and rotates the pedal assembly 200, so that the first clamping member 300 moves from the unlocked position to the locked position; when the first clamping member 300 is subjected to force to move along the second moving direction, it is used to move the first clamping member 300 from the locked position to the unlocked position.

[0043] Reference Figure 6 and Figure 9 , at this time, the first clamping member 300 is in the unlocked position, so that the pedal assembly 200 is in a free state. In this embodiment, the first clamping member 300 is defined as Figure 6 The direction from bottom to top is the first moving direction, and correspondingly, the first clamping member 300 is defined as Figure 6 The direction from top to bottom is the second moving direction. When the second clamping member 400 is disengaged from the first clamping member 300 by a force, the first clamping member 300 moves along the first moving direction, so that the first clamping member 300 moves from the unlocked position to the locked position and is engaged with the pedal assembly 200, so that the pedal assembly 200 is in a locked state (such as Figure 2 and Figure 5 status shown).

[0044] Similarly, refer to Figure 2 and Figure 5 When the first clamping member 300 is subjected to a force to move along the second moving direction (ie Figure 2 When the first clamping member 300 is moved from the locked position to the unlocked position (from top to bottom), the first clamping member 300 is disengaged from the pedal assembly 200, so that the pedal assembly 200 is in a free state, and the first clamping member 300 is in a clamping state with the second clamping member 400 (as shown in FIG. Figure 6 and Figure 9 status shown).

[0045] Preferably, the first moving direction of the first clamping member 300 intersects with the rotation centerline of the wheel body 100 .

[0046] In one embodiment, the wheel body 100 includes a wheel hub 110 and a hub cover 120 connected to the wheel hub 110, a movable groove 111 is provided on the wheel hub 110, and a first movable channel is formed between the movable groove 111 and the hub cover 120, the first clamping member 300 is movably arranged in the first movable channel, and one end of the first clamping member 300 and the second clamping member 400 both pass through the hub cover 120 and are exposed on the outside of the wheel body 100.

[0047] The connection between the wheel hub 110 and the hub cover 120 can be achieved by threaded connection or clamping. The movable groove 111 on the wheel hub 110 can be integrally formed with the wheel hub 110 or separately provided. The first movable channel formed between the movable groove 111 and the hub cover 120 is used to provide space for the movement of the first clamping member 300. One end of the first clamping member 300 and the second clamping member 400 both pass through the hub cover 120 and are exposed on the outside of the wheel body 100, so as to construct a fulcrum when the first clamping member 300 and the second clamping member 400 are subjected to force, making it convenient for the operator to push the first clamping member 300 and the second clamping member 400.

[0048] In one embodiment, a first guide column 112 and a limiting portion 113 are provided on the wheel hub 110, and a guide groove 310 is provided on the first clip 300. The guide groove 310 is movably sleeved on the outer side of the first guide column 112 to provide guidance for the movement of the first clip 300. When the first clip 300 is in the locked position, the end of the first clip 300 is pressed against the limiting portion 113 to provide limitation for the first clip 300.

[0049] In one embodiment, a first elastic member 130 is provided in the wheel hub 110, and the two ends of the first elastic member 130 are respectively pressed against the first clamping member 300 and the wheel hub 110, so as to push the first clamping member 300 from the unlocked position to the locked position when the second clamping member 400 is disengaged from the first clamping member 300.

[0050] The first elastic member 130 is preferably a spring. The first elastic member 130 is used to provide a source of power for the first clip 300 to move from the unlocked position to the locked position. Furthermore, when the first clip 300 is in the locked position, the first elastic member 130 remains in an elastically stored energy state, providing thrust to the first clip 300, preventing the first clip 300 from disengaging from the locked position without force applied during travel.

[0051] In one embodiment, a second movable channel connected to the first movable channel is provided in the wheel hub 110, the second clamping member 400 is movably provided in the second movable channel, and a second elastic member 140 is provided in the second movable channel, one end of the second elastic member 140 is pressed against the side wall of the second movable channel, and the other end is pressed against the second clamping member 400, so as to push the second clamping member 400 to move to engage with the first clamping member 300 when the first clamping member 300 moves to the unlocked position.

[0052] The second movement channel forms a space for the second clamping member 400 to move on the wheel body 100. The second elastic member 140 is preferably a spring. When the first clamping member 300 is in the locked position and the second clamping member 400 is disengaged therefrom, the second elastic member 140 is in an elastic energy storage state, providing a source of power for the second clamping member 400 to move and engage with the first clamping member 300 when the first clamping member 300 moves from the locked position to the unlocked position. Furthermore, when the second clamping member 400 is engaged with the first clamping member 300 so that the first clamping member 300 is fixed in the unlocked position, the second elastic member 140 is still in an elastic energy storage state, and is used to provide thrust to the second clamping member 400 when the second clamping member 400 is in the engaged state with the first clamping member 300, so as to prevent the first clamping member 300 from moving from the unlocked position to the locked position under the push of the first elastic member 130 due to the disengagement of the second clamping member 400 from the first clamping member 300 during the driving of the baby carriage, thereby ensuring the stability of the wheel assembly during use.

[0053] In one embodiment, a first abutting portion 320 and a second abutting portion 330 are provided at one end of the first clamping member 300 facing the movable groove 111, and the maximum distance between the second abutting portion 330 and the movable groove 111 is greater than the maximum distance between the first abutting portion 320 and the movable groove 111. A limiting surface 340 is formed between the first abutting portion 320 and the second abutting portion 330, and a guide hole 350 is provided on the second abutting portion 330 that passes through the first clamping member 300. A second guide column 410 is provided on the second clamping member 400, and the second guide column 410 passes through the guide hole 350 and the hub cover 120 in sequence. When the second clamping member 400 is clamped with the first clamping member 300, it abuts against the second abutting portion 330, and the end face of the second clamping member 400 is tightly pressed against the limiting surface 340 to provide a limit for the first clamping member 300.

[0054] Reference Figure 5 and Figure 10 At this time, the first clamping member 300 is in the locked position, and the second clamping member 400 is in abutment with the first abutting portion 320. After the first clamping member 300 is forced to move from the locked position to the unlocked position, the second clamping member 400 moves into the second abutting portion 330. Since the maximum distance between the second abutting portion 330 and the movable groove 111 is greater than the maximum distance between the first abutting portion 320 and the movable groove 111, the second abutting portion 330 forms a groove structure. When the second clamping member 400 abuts the second abutting portion 330, the second clamping member 400 penetrates into the first clamping member 300, and the first clamping member 300 is fixed by the abutment between the second clamping member 400 and the limiting surface 340, thereby fixing the first clamping member 300 in the unlocked position.

[0055] In one embodiment, it also includes a wheel frame 500, on which a locking block 510 is movably provided, and a third elastic member 530 is pressed between the locking block 510 and the wheel frame 500; the pedal assembly 200 includes: a rotating shaft 210, which is rotatably connected to the wheel body 100, and a first clamping groove 211 is provided on the rotating shaft 210, and the first clamping member 300 is movably clamped with the first clamping groove 211; a rotating shaft sleeve 220, which is rotatably connected to the wheel frame 500, and rotating shaft sleeves 220 are rotatably provided at both ends of the rotating shaft 210 along the axial direction, each rotating shaft sleeve 220 is provided with a second clamping groove 221, and the locking block 510 is sleeved on the outer side of the rotating shaft sleeve 220 and movably abuts against the second clamping groove 221; a pedal 230, and a pedal 230 is fixed to each rotating shaft sleeve 220.

[0056] The first clamping member 300 and the second clamping member 400 are preferably block-shaped structures, which can increase the engagement area between the first clamping member 300 and the first engaging groove 211, as well as the contact area between the second clamping member 400 and the second abutting portion 330. When the first clamping member 300 is in the locked position and the second clamping member 400 is engaged with the first clamping member 300, the stability of the wheel assembly of this solution can be increased.

[0057] The third elastic member 530 is preferably a spring. Figure 5 and Figure 9, the third elastic member 530 presses against the locking block 510, so that the locking block 510 is clamped in the second clamping groove 221. The pedal 230 is fixed to the wheel frame 500 in a rotationally connected manner through the rotating shaft sleeve 220. Preferably, an end cover 520 is connected to the wheel frame 500, and a third moving space is formed between the end cover 520 and the wheel frame 500 for the locking block 510 to move relative to the wheel frame 500. One end of the locking block 510 passes through the end cover 520 and is exposed on the outside of the wheel frame 500, which is used to provide a force point for the operator to push the locking block 510. When along Figure 9 When the locking block 510 is pushed upward from the bottom until the end thereof is exposed outside the wheel frame 500, the locking block 510 overcomes the elastic force of the third elastic member 530 and moves, thereby disengaging from the second engaging groove 221. At this point, under the action of an external force, the pedal 230 and the rotating shaft sleeve 220 can be pulled off the rotating shaft 210, allowing the pedal 230 to be separated from the wheel body 100, thereby meeting the user's other usage needs.
