Description

Technical Field

[0001] This utility model relates to the field of child seat technology, specifically to an adjustable footrest structure and a child safety seat. Background Technology

[0002] As children grow taller, their legs dangle and hang unsupported when seated in a child safety seat, putting greater pressure on their thighs and affecting comfort during extended periods. Current child safety seats typically have a footrest anchor bolted to the front, with a footrest plate fitted onto it for the child to step on. However, when the footrest is not needed, the anchor and footrest take up considerable space, making the entire child safety seat bulky and inconvenient to store. Removing the footrest requires tools to detach the entire anchor and footrest, and reassembling them requires additional tools, resulting in a space-consuming and inconvenient storage solution. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides an adjustable foot pedal structure, including a base module, a support leg, and an adjusting member. The adjusting member is connected to the support leg and is adapted to be fixed at different height positions of the support leg. Two foot pedals are symmetrically arranged on the adjusting member, and both foot pedals are detachably plugged into the adjusting member. The adjusting member and the two foot pedals can be synchronously adjusted relative to the support leg. The support leg is hinged to the base module, and the base module has a folding storage slot. When the support leg rotates relative to the base module, the support leg and the adjusting member are adapted to be stored in the folding storage slot.

[0004] Optionally, the adjusting member is fixedly provided with mounting rails on both the left and right sides, and the bottom of the foot pedal is provided with a docking slot adapted to the mounting rail, and the mounting rail is inserted into the docking slot.

[0005] Optionally, the mounting rail is a T-shaped rail or a dovetail rail, and the mating slot is a T-slot or a dovetail slot.

[0006] Optionally, the adjustable foot pedal structure further includes a self-locking component connected to and moving synchronously with the adjusting member to lock or unlock the movement of the adjusting member.

[0007] Optionally, an adjustment fixing plate is installed on the support leg. The adjustment fixing plate has multiple stop holes spaced apart along the vertical direction. The adjustment member is slidably connected to the adjustment fixing plate. The self-locking component includes an adjustment fixing pin. One end of the adjustment fixing pin is inserted into the adjustment member, and the other end is adapted to be inserted into any of the stop holes to lock the movement of the adjustment member.

[0008] Optionally, a mounting groove is provided on one side of the support leg, and the adjusting fixing plate is inserted into the mounting groove.

[0009] Optionally, the adjusting element is sleeved on the supporting leg and the adjusting fixing plate.

[0010] Optionally, the outer wall of the adjusting member is provided with a pin hole, and the adjusting fixing pin includes a pin rod and a pin head that are fixedly connected. The pin head is located inside the adjusting member to be inserted into the gear hole. The outer diameter of the pin head is larger than the diameter of the pin hole. The pin rod is inserted into the pin hole, and the end of the pin rod away from the pin head is located outside the adjusting member.

[0011] Optionally, the self-locking assembly further includes an elastic drive member, which is sleeved on the pin. The two ends of the elastic drive member abut against the inner wall of the adjusting member and the pin head, respectively, so as to drive the pin head to always tend to insert into the gear hole.

[0012] Optionally, the self-locking assembly further includes a handle located outside the adjusting member and connected to the side of the pin away from the pin head.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] 1. The support leg is a component that comes with the child safety seat itself. The footrest is connected by the existing support leg, eliminating the need for an additional footrest connection structure, which reduces costs. The footrest and adjustment mechanism are designed as a detachable plug-in connection structure. When the footrest is not in use or during the transportation of the child safety seat, the footrest can be removed without tools. Then the support leg and adjustment mechanism can be folded and stored in the folding storage groove, so that the child safety seat occupies less space when the footrest is not in use.

[0015] 2. Compared to a single, integrated pedal, splitting the pedal into two reduces its size, resulting in less space occupied during use.

[0016] 3. All support legs of the same model have mounting slots, which allows the adjustment plate and foot pedal to be installed on support legs of the same model that do not have foot pedals, making them highly versatile.

[0017] 4. The adjusting plate is inserted into the mounting slot. The adjusting component is a structure that is sleeved on the support leg. If the support leg is used alone, simply remove the foot pedal. The adjusting component can remain on the support leg, so that the space occupied by the support leg is not much different from that when the adjusting component is not installed.

[0018] 5. The adjustable component can move and adjust the foot pedal on the support leg, so that the height of the foot pedal can be adjusted according to children of different heights, meeting the travel needs of children of different ages and heights. At the same time, the self-locking component can lock the adjustable component after the height is adjusted, so that the foot pedal is not easy to move down under pressure, thus improving the stability of the foot pedal after adjustment.

[0019] In addition, this utility model provides a child safety seat, including the adjustable footrest structure described above.

[0020] Compared to existing technologies, the child safety seat described in this utility model has the same advantages as the aforementioned adjustable footrest structure, which will not be repeated here. Attached Figure Description

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-7 This application will be described in further detail.

[0030] The accompanying drawings of this utility model embodiment provide a coordinate system XYZ, where the positive direction of the X-axis represents the right, the negative direction of the X-axis represents the left, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0031] In a first aspect, this utility model embodiment provides an adjustable foot pedal structure, referring to... Figures 1 to 3 The adjustable footrest structure includes a base module 1, a support leg 2, an adjusting member 21, and a self-locking component 3. A connecting module 11 is provided on the front side of the base module 1, and the support leg 2 is hinged to the connecting module 11 for folding and storage. In another embodiment, the connecting module 11 can be omitted, and the support leg 2 can be directly hinged to the base module 1. Two footrests 22 are symmetrically provided on the adjusting member 21, and both footrests 22 are detachably plugged into the adjusting member 21. The adjusting member 21 is fitted onto the support leg 2, and is adapted to move the two footrests 22 to different height positions on the support leg 2 to meet the travel needs of children of different ages and heights. The self-locking component 3 is connected to the adjusting member 21 and moves synchronously, suitable for locking or unlocking the movement of the adjusting member 21. The base module 1 has a folding storage slot 12 at the bottom. When the foot pedals 22 are not in use or the child safety seat is being transported, the two foot pedals 22 can be removed from the adjustment piece 21 by hand without the use of tools. Then, the support leg 2 is rotated relative to the base module 1, so that the support leg 2 and the adjustment piece 21 are stored in the folding storage slot 12, reducing the space occupied.

[0032] In another embodiment, the adjusting member 21 and the self-locking component 3 may be omitted, and the foot pedal 22 may be directly plugged into the support leg 2.

[0033] Reference Figures 2 to 4 The support leg 2 is a component integrated into the child seat itself. The support leg 2 is telescopic, adjustable, and lockable (in existing technology, the support leg 2 includes a fixing component and a telescopic component; the specific structure will not be elaborated further). It abuts against the bottom surface in front of the car seat to provide support and prevent the seat from tipping over during sudden braking. The fixing component in the support leg 2 is hinged to the connecting module 11 via a pin. The adjusting component 21 is located on the fixing component in the support leg 2; therefore, when the length of the support leg 2 is adjusted, the adjusting component 21 will not rise or fall synchronously with the telescopic component in the support leg 2.

[0034] Reference Figures 2 to 5The top of the adjusting component 21 has a through groove that extends vertically through the adjusting component 21. The support leg 2 is inserted into the through groove, allowing the adjusting component 21 to move vertically along the support leg 2 for adjustment. Mounting rails 211 are integrally formed on both the left and right sides of the adjusting component 21, extending vertically. The bottom of each foot pedal 22 has a mating slot 221 adapted to the mounting rail 211. The mating slot 221 is vertically oriented and does not penetrate the foot pedal 22. When the mounting rail 211 is inserted into the mating slot 221, it supports the foot pedal 22 because the slot does not penetrate it. When the adjusting component 21 is locked by the self-locking component 3, the foot pedal 22 will not move downwards relative to the adjusting component 21 due to gravity or foot pressure. When not in use, applying an upward force to the foot pedal 22 allows it to be removed and stored separately without tools, improving the ease of disassembly. Furthermore, compared to a single foot pedal, splitting the foot pedal 22 into two reduces its size, resulting in less space occupied during use. Additionally, the separate processing of the two foot pedals 22 also simplifies manufacturing.

[0035] The mounting rail 211 can be a T-shaped rail or a dovetail rail; the mating slot 221 can be a T-slot or a dovetail slot. In this embodiment, the mounting rail 211 is preferably a T-shaped rail and the mating slot 221 can be a T-slot. This makes it impossible for the foot pedal 22 to be pulled off in the left and right direction, but only upward, which improves the stability of the foot pedal 22 after installation.

[0036] Reference Figures 2 to 5 The inner side of the support leg 2 fixing member (the side closest to the base module 1) is provided with a mounting groove 23 (a structure unique to some support legs 2). The length direction of the mounting groove 23 is vertical, and the mounting groove 23 passes through the top of the support leg 2 fixing member. An adjustment fixing plate 24 is inserted into the mounting groove 23. The adjustment fixing plate 24 is also inserted into the through groove. The adjustment member 21 is locked with the adjustment fixing plate 24 by the self-locking component 3. In another embodiment, the adjustment fixing plate 24 can be fixed to the outer wall of the support leg 2 by bolts.

[0037] Compared to the structure where the adjustment fixing plate 24 is located on the outside of the support leg 2 and fixedly connected to the support leg 2, the adjustment fixing plate 24 is inserted into the mounting groove 23, which reduces the space occupied by the adjustment fixing plate 24 and ensures that the space in the thickness direction of the support leg 2 itself does not change. In addition, the adjustment fixing plate 24, the adjustment component 21, and the foot pedal 22 can be installed on the same type of support leg 2 that has a mounting groove 23 but does not have a foot pedal 22, making it more versatile.

[0038] Reference Figures 2 to 5An outer tube plug 25 is snapped into the opening at the top of the mounting slot 23. The outer tube plug 25 can block the opening at the top of the mounting slot 23, making it difficult for the adjusting fixing plate 24 to move or detach vertically from the mounting slot 23. Both sides of the opening of the mounting slot 23 near the base module 1 have integrally formed blocking strips. The distance between the two blocking strips is less than the width of the adjusting fixing plate 24, preventing the adjusting fixing plate 24 from detaching from the opening of the mounting slot 23 near the base module 1. During installation, the adjusting fixing plate 24 can be inserted into the mounting slot 23 from the opening of the mounting groove at the top of the support leg 2 fixing member.

[0039] The adjusting plate 24 has multiple stop holes 241 on the side near the opening on the support leg 2. The multiple stop holes 241 are arranged at intervals in the vertical direction, and all of the multiple stop holes 241 are located between two blocking bars. The self-locking component 3 can be inserted into any of the stop holes 241 to lock the movement of the adjusting member 21, or can be completely disengaged from the corresponding stop hole 241 to allow the adjusting member 21 to move.

[0040] Reference Figures 2 to 7 The self-locking assembly 3 includes an adjusting pin 31, an elastic drive member 32, and a handle 33. One end of the adjusting pin 31 is inserted into the adjusting member 21, and the other end is adapted to be inserted into any of the gear holes 241 to lock the movement of the adjusting member 21. The elastic drive member 32 is connected to the adjusting pin 31 to drive the adjusting pin 31 to always tend to insert into the gear hole 241. When no pulling force is applied to the adjusting pin 31, the adjusting pin 31 will automatically insert into the corresponding gear hole 241 under the action of the elastic drive member 32, and it is not easy to disengage from the gear hole 241 due to vibration, thus improving the stability of the adjusting member 21 after locking. The handle 33 is connected to the adjusting pin 31 so that the user can pull the adjusting pin 31 when adjusting the height of the foot pedal 22, thereby driving the adjusting pin 31 to move and unlock.

[0041] Reference Figures 2 to 7Specifically, a pin hole 212 is provided on the back of the adjusting component 21 (the side near the base module 1), and the pin hole 212 communicates with the through groove. The adjusting fixing pin 31 includes an integrally formed pin rod 311 and a pin head 312. The pin head 312 is located at the end of the pin rod 311 near the adjusting fixing plate 24, and the pin head 312 is located in the through groove. The outer diameter of the pin head 312 is larger than the diameter of the pin hole 212. The pin rod 311 is inserted into the pin hole 212, and the end of the pin rod 311 away from the pin head 312 is located outside the adjusting component 21 in a cantilevered state. The elastic driving component 32 is a spring. In another embodiment, the elastic driving component 32 can be an elastic rubber column. The spring is located in the through groove and is sleeved on the pin rod 311. One end of the spring abuts against the groove wall of the through groove; the other end abuts against the pin head 312, thereby driving the pin head 312 to be inserted into the stop hole 241. The handle 33 is a metal ring with a notch. The outer wall of the pin 311 away from the pin head 312 has a connecting hole. The handle 33 is inserted into the connecting hole through the notch and then connected to the pin 311. When unlocking is required, the adjusting pin 31 can be moved by pulling the handle 33, so that the pin head 312 disengages from the stop hole 241.

[0042] Since the outer diameter of the pin head 312 is larger than the outer diameter of the pin hole 212, when a pulling force is applied to the adjusting fixing pin 31, the pin head 312 will completely disengage from the stop groove and abut against the groove wall of the through groove, thus limiting the movement of the adjusting fixing pin 31. There is no need to worry that the adjusting fixing pin 31 will come out of the pin hole 212 due to the pulling force.

[0043] Since the end of the pin 311 furthest from the pin head 312 is located outside the adjusting member 21 and is in a cantilevered state, in another embodiment, the handle 33 can be omitted, and the cantilevered part of the pin 311 can be pulled directly during adjustment. In yet another embodiment, the elastic drive member 32 and the handle 33 can be omitted, and the adjusting fixing pin 31 can be directly inserted into the stop hole 241 and tightly fitted with the stop hole 241.

[0044] The implementation principle of the adjustable footrest structure in this embodiment is as follows: the adjusting component 21 can drive the footrest 22 to adjust its height on the supporting leg 2, meeting the travel needs of children of different ages and heights. The supporting leg 2 is a component carried by the child safety seat itself, and the footrest 22 is connected using the existing component, without the need for an additional connection structure for the footrest 22. The mounting rail 211 and the docking slot 221 cooperate to connect the footrest 22 and the adjusting component 21. When the footrest 22 is not in use or during the transportation of the child safety seat, the footrest 22 can be directly removed without tools. Then, the supporting leg 2 and the adjusting component 21 can be folded and stored in the folding storage groove, so that the child safety seat occupies less space when the footrest 22 is not in use, and the footrest 22 is also easy to disassemble. The adjusting plate 24 is inserted into the mounting slot 23, and the adjusting element 21 is fitted onto the support leg 2. If the support leg 2 is used alone, the foot pedal 22 can be removed, leaving the adjusting element 21 on the support leg 2, so that the space occupied by the support leg 2 is not significantly different from that without the adjusting element 21. Furthermore, support legs 2 of the same type, which have a mounting slot 23 but do not include a foot pedal 22, can also have the adjusting plate 24 and foot pedal 22 installed, demonstrating strong versatility.

[0045] Secondly, another embodiment of the present invention provides a child safety seat, including the adjustable footrest structure described in the first aspect.
