Description

Technical Field

[0001] This utility model relates to the field of children's vehicle technology, and in particular to a multifunctional children's vehicle. Background Technology

[0002] Child vehicles are essential tools in modern family childcare, playing a vital role in ensuring children's safety and convenient travel in various scenarios such as home life, dining out, and playing in parks. With the diversification of childcare needs, parents are placing higher demands on the functionality and applicability of child vehicles.

[0003] However, most child vehicles on the market currently suffer from limited functionality and poor adjustability. Specifically, existing child vehicles can usually only be used as fixed seats, and the angle and horizontal position of the seat cannot be adjusted or the adjustment method is not flexible enough, making it unable to adapt to various usage scenarios and severely restricting the practicality and user experience of child vehicles.

[0004] Therefore, there is an urgent need to develop a multifunctional child vehicle to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional child carrier that can switch between seat mode and cradle mode, and can flexibly adjust the angle and horizontal position of the carrier to adapt to various usage scenarios and improve the user experience.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A multifunctional child vehicle includes a frame, a vehicle body, a seat, a joint, a rotating base, a fixed base, a translation adjustment mechanism, and an angle adjustment mechanism. The seat is connected to the frame, and the joint is connected to the vehicle body.

[0008] The fixed base is rotatably connected to the card seat, and the angle adjustment mechanism is provided between the joint and the fixed base. The angle adjustment mechanism is movably connected to the fixed base and can engage with the joint.

[0009] The first end of the rotating seat is rotatably connected to the fixed seat, and the second end of the rotating seat is rotatably connected to the card seat along with its first end. When the first end of the rotating seat rotates relative to the fixed seat, the second end of the rotating seat rotates synchronously in the opposite direction relative to the card seat, so that the vehicle can translate while maintaining the same tilt angle.

[0010] The translation adjustment mechanism is provided between the rotating seat and the fixed seat. The translation adjustment mechanism includes a first locking component and a first connecting component. The first connecting component is movably connected to the fixed seat and can engage with the first end of the rotating seat. The first locking component has a translation locking position for engaging the first connecting component with the rotating seat, a translation unlocking position for disengaging the engagement, and a cradle unlocking position. When the first locking component is in the cradle unlocking position, the first locking component engages with the first connecting component, so that the vehicle can swing freely.

[0011] In some optional embodiments, a first movable gear protrudes from the side of the fixed seat near the rotating seat, and a first receiving groove is opened at the first end of the rotating seat to accommodate the rotation of the first movable gear. A second movable gear is rotatably connected inside the rotating seat, and a third movable gear is rotatably connected inside the card holder. The first movable gear, the second movable gear, and the third movable gear are sequentially meshed and connected so that the vehicle can translate while maintaining the same tilt angle.

[0012] In some optional embodiments, the first locking component includes a first elastic element, and the first connecting component includes a movable engaging gear, which is sleeved on the first movable gear and meshes with it. The movable engaging gear has teeth, and the rotating seat has a slot corresponding to the teeth. The first elastic element is disposed between the fixed seat and the movable engaging gear to drive the teeth of the movable engaging gear to engage with the slot, so that the first ends of the fixed seat and the rotating seat stop rotating.

[0013] In some optional embodiments, the movable engaging gear has a first guide groove extending along its axial direction. The width of the first guide groove gradually increases along the axial direction of the first movable gear towards the rotating seat. The first locking component also includes an unlocking lever, which is rotatably sleeved on the movable engaging gear. The unlocking lever has a first guide block corresponding to the first guide groove. When the first guide block engages with the end of the first guide groove away from the rotating seat, the locking teeth engage with the slot. When the unlocking lever rotates, the first guide block pushes the movable engaging gear, causing the locking teeth to move away from the slot.

[0014] In some optional embodiments, the movable engaging gear is further provided with a second guide groove adjacent to the first guide groove. The width of the second guide groove gradually increases along the axial direction of the first movable gear toward the rotating seat, and the depth of the second guide groove is less than the depth of the first guide groove. When the first guide block engages with the end of the second guide groove away from the rotating seat, the engaging tooth disengages from the engaging groove.

[0015] In some alternative embodiments, the first guide groove and the second guide groove have a smooth transition.

[0016] In some optional embodiments, the angle adjustment mechanism includes a second locking component and a second connecting component. The second connecting component is movably disposed within the joint and has an angle locking position that engages with the fixed seat and an angle unlocking position that releases the engagement. The second locking component is connected to the second connecting component, enabling the second connecting component to move between the angle locking position and the angle unlocking position.

[0017] In some optional embodiments, the second locking component includes a second elastic element, the second connecting component includes an angle-engaging gear, a first gear groove is provided in the joint, and a first limiting shaft is protruding from the center of the first gear groove, a second gear groove corresponding to the first gear groove is provided on the side of the fixed seat near the joint, and a second limiting shaft adapted to the shape and size of the first limiting shaft is protruding from the center of the second gear groove, the angle-engaging gear is sleeved on the second limiting shaft, the second elastic element is disposed between the angle-engaging gear and the fixed seat, and the second elastic element is configured to cause the angle-engaging gear to engage simultaneously with the first gear groove and the second gear groove, so that the fixed seat and the joint are prevented from rotating.

[0018] In some optional embodiments, the second locking component further includes an angle unlocking turntable and a rope. The angle unlocking turntable is sleeved on the first limiting shaft and abuts against the angle engaging gear. A second guide block protrudes from the first gear groove. The width of the second guide block gradually decreases along the axial direction of the first gear groove towards the angle unlocking turntable. The angle unlocking turntable has a third guide groove that matches the shape of the second guide block. One end of the rope extends outside the joint, and the other end is connected to the angle unlocking turntable to drive the angle unlocking turntable to rotate. When the rope drives the angle unlocking turntable to rotate, the second guide block pushes the angle engaging gear to move into the second gear groove.

[0019] In some alternative embodiments, the second locking component further includes an angle unlock button movably connected to the vehicle and driven by the rope, which can drive the rope to move away from the angle unlock turntable.

[0020] In some alternative embodiments, the angle unlock button is located at the upper end of the vehicle.

[0021] The beneficial effects of this utility model are:

[0043] like Figures 1 to 8 As shown, this embodiment provides a multifunctional child vehicle that can switch between a normal seat mode and a cradle mode, and can flexibly adjust the angle and horizontal position of the vehicle 1, thereby adapting to various usage scenarios and improving the user experience.

[0044] The multi-functional child vehicle includes a frame, a vehicle body 1, a seat 2, a joint 3, a rotating seat 4, a fixed seat 5, a translation adjustment mechanism 6, and an angle adjustment mechanism 7. The seat 2 is connected to the frame, and the joint 3 is connected to the vehicle body 1.

[0045] The fixed base 5 is rotatably connected to the card seat 2. By rotating the joint 3 relative to the fixed base 5, the angle of the vehicle 1 can be flexibly adjusted. An angle adjustment mechanism 7 is provided between the joint 3 and the fixed base 5. The angle adjustment mechanism 7 is movably connected to the fixed base 5 and can engage with the joint 3 to prevent the joint 3 from rotating with the fixed base 5, thereby locking the tilt angle of the vehicle 1.

[0046] The first end of the rotating seat 4 is rotatably connected to the fixed seat 5, and the second end of the rotating seat 4 is rotatably connected to the card seat 2 along with the first end. When the first end of the rotating seat 4 rotates relative to the fixed seat 5, the second end of the rotating seat 4 rotates synchronously in the opposite direction relative to the card seat 2, so that the vehicle 1 can be translated on the basis of the unchanged tilt angle, thereby flexibly adjusting the position of the vehicle 1 in the horizontal direction and keeping the tilt angle of the vehicle 1 unchanged.

[0047] The rotating seat 4 and the fixed seat 5 are provided with a translation adjustment mechanism 6. The translation adjustment mechanism 6 includes a first locking component 61 and a first connecting component. The first connecting component is movably connected to the fixed seat 5 and can be engaged with the first end of the rotating seat 4. The first locking component 61 has a translation locking position for engaging the first connecting component with the rotating seat 4, a translation unlocking position for disengaging the engagement, and a cradle unlocking position.

[0048] When the first locking component 61 is in the translational locking position, the first connecting component is engaged with the first end of the rotating seat 4, so that the fixed seat 5 and the first end of the rotating seat 4 stop rotating, and the second end of the rotating seat 4 stops rotating synchronously with the card seat 2, thereby locking the horizontal position of the carrier 1.

[0049] When the first locking component 61 is in the translation unlock position or the cradle unlock position, the first connecting component is disengaged from the rotating seat 4, and the first end of the fixed seat 5 and the rotating seat 4 can rotate relative to each other. The second end of the rotating seat 4 rotates synchronously with its first end relative to the locking seat 2, thereby enabling the translation of the vehicle 1.

[0050] Furthermore, when the first locking component 61 is in the cradle unlock position, the first locking component 61 is engaged with the first connecting component, so that the first connecting component remains in the position of being unengaged from the rotating seat 4. The first end of the fixed seat 5 and the rotating seat 4 can rotate freely relative to each other, and the second end of the rotating seat 4 can rotate synchronously with its first end relative to the locking seat 2, so that the vehicle 1 can swing freely, thereby realizing the cradle function of the multifunctional child vehicle.

[0051] like Figure 2 As shown, in this embodiment, a first movable gear 8 is protruding from the side of the fixed seat 5 near the rotating seat 4. A first receiving groove 41 for accommodating the rotation of the first movable gear 8 is opened at the first end of the rotating seat 4. A second movable gear 9 is rotatably connected inside the rotating seat 4, and a third movable gear 10 is rotatably connected inside the card holder 2. The first movable gear 8, the second movable gear 9, and the third movable gear 10 are sequentially meshed and connected, so that when the first end of the rotating seat 4 rotates relative to the fixed seat 5, the second end of the rotating seat 4 rotates synchronously and in the opposite direction relative to the card holder 2. When the first end of the rotating seat 4 is fixed relative to the fixed seat 5, the second end of the rotating seat 4 is fixed synchronously relative to the card holder 2.

[0052] In an optional embodiment, the fixed seat 5 has a driving pulley protruding on the side near the rotating seat 4, and the first end of the rotating seat 4 has a second receiving groove for accommodating the rotation of the driving pulley. A driven pulley is rotatably connected inside the clamping seat 2, and a synchronous belt is tensioned between the driving pulley and the driven pulley. When the fixed seat 5 rotates relative to the first end of the rotating seat 4, the second end of the rotating seat 4 is forced to rotate at the same angular velocity through the meshing transmission of the synchronous belt, and the two rotate in opposite directions. This also enables the second end of the rotating seat 4 to rotate synchronously with its first end and be connected to the clamping seat 2, so that the carrier 1 can translate while maintaining the same tilt angle. This is not limited here.

[0053] In another optional embodiment, two connecting rods are eccentrically connected to the side of the fixed seat 5 near the rotating seat 4. The two connecting rods are arranged in parallel and spaced apart, and the ends of the two connecting rods away from the fixed seat 5 are eccentrically connected to the card seat 2, forming a parallel linkage mechanism. This allows the rotational motion of the fixed seat 5 relative to the first end of the rotating seat 4 to be converted into the synchronous reverse rotation of the second end of the rotating seat 4 relative to the card seat 2 through the connecting rods. This also enables the carrier 1 to translate while maintaining the same tilt angle. This is not limited here.

[0054] Furthermore, the first locking component 61 includes a first elastic element 611, and the first connecting component includes a movable engaging gear 62. The movable engaging gear 62 is sleeved on the first movable gear 8 and meshes with the first movable gear 8. The movable engaging gear 62 is provided with teeth 621. The rotating seat 4 is provided with a groove 42 corresponding to the teeth 621. The first elastic element 611 is disposed between the fixed seat 5 and the movable engaging gear 62 and is used to drive the teeth 621 of the movable engaging gear 62 to engage with the groove 42, so that the first ends of the fixed seat 5 and the rotating seat 4 stop rotating, thereby locking the horizontal position of the carrier 1.

[0055] like Figure 4As shown, in some optional embodiments, the movable engaging gear 62 has a first guide groove 622 extending axially therefrom. The width of the first guide groove 622 gradually increases axially towards the rotating seat 4. The first locking assembly 61 also includes an unlocking lever 612, which is rotatably sleeved on the movable engaging gear 62. The unlocking lever 612 has a first guide block 6121 corresponding to the first guide groove 622. When the first guide block 6121 is engaged at the end of the first guide groove 622 away from the rotating seat 4, the locking teeth 621 are engaged in the slot 42. When the user moves the unlocking lever 612, causing the unlocking lever 612 to rotate, the first guide block 6121 pushes the movable engaging gear. 62 drives the locking tooth 621 to move away from the slot 42 until the locking tooth 621 is completely disengaged from the slot 42. At this time, the first end of the fixed seat 5 and the rotating seat 4 can rotate relative to each other, and the second end of the rotating seat 4 rotates synchronously relative to the locking seat 2, thereby adjusting the horizontal position of the vehicle 1. After the adjustment is completed, the unlocking lever 612 is released, and the moving engaging gear 62 moves towards the rotating seat 4 under the action of the first elastic element 611. The locking tooth 621 engages with the slot 42. At the same time, the first guide block 6121 automatically resets to the end of the first guide groove 622 away from the rotating seat 4 under the action of the side wall of the first guide groove 622, so that the locking tooth 621 engages with the slot 42, thereby locking the horizontal position of the vehicle 1.

[0056] In some optional embodiments, the movable engaging gear 62 is further provided with a second guide groove 623 adjacent to the first guide groove 622. The width of the second guide groove 623 gradually increases along the axis of the first movable gear 8 toward the rotating seat 4, and the depth of the second guide groove 623 is less than the depth of the first guide groove 622. When the first guide block 6121 is engaged with the end of the second guide groove 623 away from the rotating seat 4, the locking tooth 621 disengages from the locking groove 42, and the first end of the fixed seat 5 and the rotating seat 4 can rotate freely relative to each other. The second end of the rotating seat 4 can rotate freely relative to the locking seat 2 in sync, thereby realizing the cradle rocking function of the carrier 1.

[0057] It should be noted that the depth of the second guide groove 623 is the length of the second guide groove 623 extending away from the rotating seat 4 along the axial direction of the first moving gear 8, and the depth of the first guide groove 622 is the length of the first guide groove 622 extending away from the rotating seat 4 along the axial direction of the first moving gear 8.

[0058] In some optional embodiments, the first guide groove 622 and the second guide groove 623 are smoothly transitioned so that the fixing block 716 of the unlocking lever 612 can move smoothly directly between the first guide groove 622 and the second guide groove 623, thereby improving the convenience of the multi-functional switching of the vehicle 1 and the user experience.

[0059] like Figure 2 and Figure 3 As shown, in some optional embodiments, the angle adjustment mechanism 7 includes a second locking component 71 and a second connecting component. The second connecting component is movably disposed within the joint 3 and has an angle locking position that engages with the fixed seat 5 and an angle unlocking position that releases the engagement. The second locking component 71 is connected to the second connecting component, enabling the second connecting component to move between the angle locking position and the angle unlocking position. When the second locking component 71 drives the first connecting component to the angle unlocking position, the joint 3 can rotate relative to the fixed seat 5, thereby flexibly adjusting the tilt angle of the vehicle 1.

[0060] In some optional embodiments, the second locking component 71 includes a second elastic element 711, the second connecting component includes an angle engaging gear 72, a first gear groove 31 is provided in the joint 3, and a first limiting shaft 32 is protruding from the center of the first gear groove 31. A second gear groove 51 corresponding to the first gear groove 31 is provided on the side of the fixed seat 5 near the joint 3, and a second limiting shaft 52 adapted to the shape and size of the first limiting shaft 32 is protruding from the center of the second gear groove 51. The angle engaging gear 72 is sleeved on the second limiting shaft 52. The second elastic element 711 is disposed between the angle engaging gear 72 and the fixed seat 5. The second elastic element 711 is configured to make the angle engaging gear 72 simultaneously engage with the first gear groove 31 and the second gear groove 51, so that the fixed seat 5 and the joint 3 stop rotating, thereby locking the tilt angle of the carrier 1.

[0061] In some optional embodiments, the second locking assembly 71 further includes an angle unlocking turntable 712 and a rope 713. The angle unlocking turntable 712 is sleeved on the first limiting shaft 32 and abuts against the angle engaging gear 72. A second guide block 33 protrudes from the first gear groove 31. The width of the second guide block 33 gradually decreases along the axial direction of the first gear groove 31 toward the angle unlocking turntable 712. The angle unlocking turntable 712 has a third guide groove 7121 that matches the shape of the second guide block 33. One end of the rope 713 extends to the outside of the joint 3, and the other end is connected to the angle unlocking turntable 712 to drive the angle unlocking turntable 712 to rotate. When the rope 713 drives the angle unlocking turntable 712 to rotate, the second guide block 33 pushes the angle engaging gear 72 to move into the second gear groove 51. When the angle engaging gear 72 is fully inserted into the second gear groove 51, the fixed seat 5 can rotate relative to the joint 3, thereby realizing the angle adjustment of the carrier 1.

[0062] like Figure 1 and Figure 5As shown, in some optional embodiments, the second locking component 71 further includes an angle unlocking button 715, which is movably connected to the carrier 1 and is connected to the rope 713. The rope 715 can drive the rope 713 to move away from the angle unlocking turntable 712, and the rope 713 can drive the angle unlocking turntable 712 to rotate, thereby causing the second guide block 33 to push the angle engaging gear 72 to move into the second gear groove 51.

[0063] Furthermore, the angle unlock button 715 is located at the top of the vehicle 1, close to the operator's position, making it easy to press the angle unlock button 715 and improving the convenience of adjusting the tilt angle of the vehicle 1.

[0064] Specifically, the second locking component 71 further includes a mounting sleeve 714 and at least two fixing blocks 716. The fixing blocks 716 are used to connect the rope body 713. The at least two fixing blocks 716 are disposed opposite to each other in the mounting sleeve 714 along the length direction of the mounting sleeve 714. The angle unlocking button 715 is slidably connected to the mounting sleeve 714 along the height direction of the mounting sleeve 714. The first end of the angle unlocking button 715 is provided with a fourth guide groove 7151. The width of the fourth guide groove 7151 gradually decreases from the first end of the angle unlocking button 715 towards the second end. The two side walls of the fourth guide groove 7151 are slidably engaged with at least one fixing block 716 respectively.

[0065] By pressing the angle unlock button 715, the angle unlock button 715 slides into the mounting sleeve 714, which drives at least two fixing blocks 716 to move closer to each other, thereby moving the rope 713 away from the angle unlock turntable 712. At the same time, the rope 713 drives the angle unlock turntable 712 to rotate, causing the second guide block 33 to push the angle engagement gear 72 into the second gear groove 51. After the angle adjustment of the vehicle 1 is completed, the angle unlock button 715 is released. Under the action of the second elastic element 711, the angle engagement gear 72 moves into the second gear groove 51. At the same time, the angle engagement gear 72 abuts against the angle unlock turntable 712, causing it to move away from the second gear groove 51. Under the action of the second guide block 33, the angle unlock turntable 712 rotates to reset, thereby driving the rope 713 and the fixing blocks 716 to reset.

[0066] It is easy to understand that, in order to improve the stability of the connection between the vehicle 1 and the frame, there are card seats 2 on both sides of the frame, and joints 3 are provided on both sides of the vehicle 1. Each joint 3 and the corresponding card seat 2 are connected through a fixed seat 5 and a rotating seat 4. The second locking component 71 is provided with two fixed blocks 716, which can be connected to a rope 713 respectively, thereby realizing the simultaneous control of the angle adjustment mechanism 7 on both sides.

[0067] In some optional embodiments, the second locking component 71 further includes a third elastic element 717 disposed between the two fixing blocks 716 for driving at least two fixing blocks 716 away from each other, thereby pushing the fixing blocks 716 and the rope 713 to reset, which helps to improve the efficiency and accuracy of the angle locking of the vehicle 1.

[0068] In addition, the two ends of the mounting sleeve 714 are connected to the interior of the vehicle 1, and the rope 713 is threaded through the vehicle 1, which can improve the uniformity and aesthetics of the appearance of the multi-functional child vehicle, and can also improve the safety of the child vehicle and eliminate potential safety hazards to children.

[0069] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
