Description

Technical Field

[0001] This utility model relates to the field of infant and child product technology, and in particular to a stroller with adjustable foot pedals. Background Technology

[0002] The footrest of a stroller is where the baby's feet rest. The angle of the footrest affects the baby's sitting posture. By adjusting the angle of the footrest, the baby's sitting posture can be adjusted to some extent, thus improving the comfort of the stroller.

[0003] In existing technologies, stroller pedals mainly employ either fixed or adjustable sliding rail structures. Fixed pedals are rigidly connected to the frame or seat bottom, making height adjustment impossible. This design is common in lightweight umbrella strollers; while simple and stable, it doesn't accommodate the developing leg muscles of children, potentially leading to legs dangling and affecting blood circulation and comfort with prolonged use. Adjustable sliding rail pedals, on the other hand, use sliding rails and locking knobs for stepless adjustment. While this expands the adjustment range, it requires two hands to operate the knobs, resulting in poor stability during movement and a risk of rail displacement due to vibration, posing a safety hazard.

[0004] In conclusion, existing stroller pedals have the drawback of failing to balance structural reliability and ease of operation. Utility Model Content

[0005] The main purpose of this invention is to propose a stroller with adjustable foot pedals, which aims to solve the shortcomings of existing stroller foot pedals that cannot balance structural reliability and ease of operation.

[0006] To achieve the above objectives, this utility model proposes a stroller with a height-adjustable footrest, comprising:

[0007] The foot pedal body is pivotally connected to the stroller's support structure;

[0008] The lifting mechanism is fixedly connected inside the pedal body and is used to drive the pedal body to rise and fall. The lifting mechanism includes an outer sliding block, an inner sliding block, a stop plate, and a locking component.

[0009] The stop plate is located inside the outer sliding block, and the outer sliding block can slide along the stop plate.

[0011] The outer sliding block has a slide rail on its outer side, and the inner sliding block can slide along the slide rail.

[0012] The outer sliding block has a longitudinal first movable groove, while the inner sliding block has an inclined second movable groove. The first and second movable grooves partially overlap, and the locking member extends into the overlapping position of the first and second movable grooves.

[0013] When the inner sliding block is in the initial position, the locking element is located at the top of the first and second movable slots.

[0014] When the inner sliding block moves along the slide rail, the locking member moves downwards into the first and second movable grooves and disengages from the stop portion;

[0015] The unlocking mechanism includes a traction component and a rope. One end of the rope is connected to the traction component, and the other end is connected to the inner sliding block.

[0016] The traction assembly is used to pull the rope to make the inner sliding block slide along the slide rail.

[0017] Furthermore, the gear shifting part includes a first gear shifting groove and a second gear shifting groove, wherein the second gear shifting groove includes a limiting part and a guiding part, wherein,

[0018] When the inner sliding block is in the initial position, the locking element is in the first stop groove.

[0019] After the inner sliding block moves along the slide rail, the locking member moves along the guide and extends into the limiting part.

[0020] Furthermore, the end of the stop plate away from the stop part is provided with a limiting track for limiting the movement distance of the outer sliding block. A limiting post is provided in the limiting track, and the limiting post can move along the limiting track. The limiting post is fixedly connected to the outer sliding block.

[0023] Furthermore, the first reset component is a spring, the outer sliding block has a first protrusion at the position where it passes through the rope, and the inner sliding block has a second protrusion, with the two ends of the spring abutting against the first and second protrusions.

[0024] Furthermore, the traction assembly includes a button block, a button cavity, and a movable rod. The button block is movably disposed within the button cavity, and the movable rod is fixedly connected to the rope. The button block has an inclined third movable groove, and the button cavity has a transverse fourth movable groove. The third and fourth movable grooves partially overlap, and the movable rod extends into the overlapping position of the third and fourth movable grooves.

[0025] When the button block is in its initial position, the movable lever is at the top of the third movable slot and at the end of the fourth movable slot closest to the rope.

[0045] This utility model proposes a stroller with adjustable foot pedals.

[0046] In this embodiment of the utility model, such as Figures 1 to 7 As shown, the stroller with a height-adjustable foot pedal includes a foot pedal body 1. The foot pedal body 1 includes a footrest 11 for accommodating feet and a tube 12 disposed below. The foot pedal body 1 is pivotally connected to the stroller's support structure. To enable the foot pedal body 1 to be raised to different heights and to achieve a limit, a lifting mechanism 2 is provided between the footrest 11 and the tube 12. The lifting mechanism 2 is fixed inside the foot pedal body 1 and is used to drive the foot pedal body 1 to rise and fall. The lifting mechanism 2 includes an outer sliding block 21, an inner sliding block 22, a stop plate 23, and a locking member 24. The stop plate 23 is disposed inside the outer sliding block 21, and the outer sliding block 21 can slide along the stop plate 23. A stop portion 231 is provided on the surface of one end of the stop plate 23, and the locking member 24 abuts against the stop portion 231. At the same time, a slide rail 211 is provided on the outer side of the outer sliding block 21, and the inner sliding block 22 can slide along the slide rail 211. In order to control the release of the locking member 24, a longitudinal first movable groove is provided in the outer sliding block 21. 212, while the inner sliding block 22 is provided with an inclined second movable groove 221. The first movable groove 212 and the second movable groove 221 partially overlap, and the locking member 24 extends into the overlapping position of the first movable groove 212 and the second movable groove 221. When the inner sliding block 22 is in the initial position, the locking member 24 is located at the top of the first movable groove 212 and the second movable groove 221. When the inner sliding block 22 moves along the slide rail 211, the locking member 24 moves downwards from the first movable groove 212 and the second movable groove 221 and disengages from the stop part 231 to complete the unlocking. In addition, in order to drive the lifting mechanism 2, the stroller also includes an unlocking mechanism 3. The unlocking mechanism 3 includes a traction component 31 and a rope 32. One end of the rope 32 is connected to the traction component 31, and the other end is connected to the inner sliding block 22. The traction component 31 is used to pull the rope 32 to make the inner sliding block 22 slide along the slide rail 211, thereby releasing the locking member 24 and switching it to different positions of the stop piece 23.

[0047] It is worth noting beforehand that the support structure described in this utility model specifically refers to the support on the stroller used to connect the foot pedal body 1. As shown in the accompanying drawings of the embodiments in this specification, the support structure refers to the seat. In this industry, the connection forms of the foot pedal body 1 are diverse. Typically, the foot pedal body 1 is set by extending the seat. In other cases, the foot pedal body 1 is also set independently above the front wheel of the stroller or through the frame adapter extension plate. Since the setting of the foot pedal body 1 is diverse, this utility model does not limit the specific installation position of the foot pedal body 1. Refer to this embodiment or the prior art.

[0048] In some embodiments of this utility model, to make the movement of the locking member 24 smoother, the stop part 231 includes a first stop groove 2311 and a second stop groove 2312. The second stop groove 2312 includes a limiting part 23121 and a guide part 23122. When the inner sliding block 22 is in the initial position, the locking member 24 is located in the first stop groove 2311. After the inner sliding block 22 moves along the slide rail 211, the locking member 24 moves along the guide part 23122 and extends into the limiting part 23121. Understandably, the guide portion 23122 is a smooth inclined surface. The guide portion 23122 and the limiting portion 23121 cooperate to make the movement of the locking member 24 between different positions 231 smoother. It should be noted that the number of second position slots 2312 is not limited. In this embodiment, in combination with practical needs, two second position slots 2312 can meet the basic daily needs. Therefore, the position piece 23 with two second position slots 2312 is shown as a preferred embodiment.

[0049] In some embodiments of this utility model, the end of the stop plate 23 away from the stop part 231 is provided with a limiting track 232 for limiting the movement distance of the outer sliding block 21. A limiting post 233 is provided in the limiting track 232. The limiting post 233 can move along the limiting track 232. The limiting post 233 is fixedly connected to the outer sliding block 21. Through the cooperation of the limiting track 232 and the limiting post 233, the outer sliding block 21 can maintain a tight fit with the stop plate 23, so as not to loosen or even fall off.

[0050] Specifically, in order to make the fixed connection between the outer sliding block 21 and the limiting post 233 more stable, preferably, the end surface of the limiting post 233 is provided with densely distributed protrusions 2331, the protrusions 2331 abutting against the outer sliding block 21, and the connection between the outer sliding block 21 and the limiting post 233 is more stable through the densely distributed protrusions 2331 abutting against the outer sliding block 21. More specifically, the shape of the protrusions 2331 is limited to a triangular pyramid shape, which is more conducive to tightly adhering to the outer sliding block 21.

[0051] In some embodiments of this utility model, in order to enable the inner sliding block 22 to be reset after moving along the slide rail 211, the portion of the rope body 32 located at the slide rail 211 is provided with a first reset component 25 for resetting the inner sliding block 22.

[0052] Furthermore, the first reset component 25 is a spring. The outer sliding block 21 has a first protrusion 213 at the position where it passes through the rope 32, while the inner sliding block 22 has a second protrusion 222. The two ends of the spring abut against the first protrusion 213 and the second protrusion 222. Since the first protrusion 213 and the second protrusion 222 extend into the ends of the spring, the spring can be stably set between the outer sliding block 21 and the inner sliding block 22. In some other embodiments of this utility model, the first reset component 25 can also be replaced by a component that stores elastic potential energy and then releases it, such as rubber, sponge, or elastic fiber. This is the prior art and will not be described in detail.

[0053] In some embodiments of this utility model, the traction assembly 31 includes a button block 311, a button cavity 312, and a movable rod 313. The button block 311 is movably disposed in the button cavity 312, and the movable rod 313 is fixedly connected to the rope 32. The button block 311 is provided with an inclined third movable groove 3111, and the button cavity 312 is provided with a transverse fourth movable groove 3121. The third movable groove 3111 and the fourth movable groove 3121 partially overlap, and the movable rod 313 extends into the third movable groove 311. The overlapping position of the first and fourth movable slots 3121, wherein when the button block 311 is in the initial position, the movable rod 313 is located at the top of the third movable slot 3111 and at the end of the fourth movable slot 3121 near the rope body 32. When the button block 311 is inserted into the button cavity 312, the movable rod 313 moves toward the bottom of the third movable slot 3111 and the end of the fourth movable slot 3121 away from the rope body 32. At this time, the movable rod 313 moves while pulling the rope body 32 to make the lifting mechanism 2 operate.

[0054] Specifically, in order to stabilize the connection between the movable rod 313 and the rope 32, a connector 33 for stabilizing the connection is provided between the rope 32 and the movable rod 313. The button cavity 312 has an opening 3122. The connector 33 extends into the opening 3122 and abuts against the inside of the button cavity 312. The connector 33 also has a through-hole 331 for passing through the movable rod 313.

[0055] Specifically, in order to enable the button block 311 to automatically reset after being moved by an external force, the button block 311 is provided with a reset groove 3112, and a second reset component 314 for resetting the button block 311 is installed in the reset groove 3112.

[0056] Furthermore, the second reset component 314 is a spring, with one end extending into and abutting against the reset groove 3112 and the other end abutting against the button cavity 312. Referring to the first reset component 25, in some other embodiments of this utility model, the second reset component 314 can also be replaced by a component that stores elastic potential energy and then releases it, such as rubber, sponge, or elastic fiber. This is the prior art and will not be described in detail.

[0057] The following content serves as an explanation of the working principle of this utility model:

[0058] It should be noted beforehand that, in order to further improve and demonstrate the ease of operation of this utility model, it is more appropriate to place the button block 311 in the unlocking mechanism 3 directly below the foot pedal body 1. However, it can also be switched to different angles during actual assembly. Generally speaking, it is sufficient for the stroller pusher to press the button block 311 with their foot. The setting direction of the button block 311 is not too restricted.

[0059] When it is necessary to raise or lower the foot pedal body 1, press the button block 311 so that it extends into the button cavity 312. The position change of the third movable groove 3111 and the fourth movable groove 3121 controls the movement of the movable rod 313, which in turn pulls the rope body 32 to move the inner sliding block 22 on the slide rail 211. After the inner sliding block 22 moves, the position change of the first movable groove 212 and the second movable groove 221 controls the locking member 24 to release. At the same time, the outer sliding block 21 slides along the stop plate 23, so that the locking member 24 moves between the first stop groove 2311 and the second stop groove 2312 or the second stop groove 2312.

[0060] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
