Description

Technical Field

[0001] The invention relates to a child carrier and an adjustment control system thereof, and in particular to a control system and a child carrier that synchronously drives a protective element and a side panel to be linked by partial folding. Background Art

[0002] The child carrier comprises a main load-bearing part and a leaning part. The main load-bearing part is mounted on a frame and has side panels. The leaning part is connected to the main load-bearing part or the frame in a hinged manner to facilitate rotation and adjustment of the leaning part.

[0003] The existing leaning part is usually connected to the main load-bearing part or the frame in two ways. One connection method is to set an adjuster between the leaning part and the main load-bearing part, and adjust and control the rotation of the leaning part through the adjuster. Using the adjuster to adjust the leaning part is easy to operate and the control is precise, but the installation of the adjuster takes up space in the child carrier, which will increase the volume of the child carrier after folding, and the use of the adjuster will also increase the cost.

[0004] Another connection method is that the leaning part is connected to the main load-bearing part or the frame through a hinged connection structure. This method requires that mutually hinged mechanical structures are set on the leaning part and the main load-bearing part or the frame, and the hinged structure is used to realize the rotation of the leaning part relative to the main load-bearing part or the frame. At the same time, a snap-fitting component is required to realize the positioning of the leaning part, and the stroke of the snap-fitting component needs to be controlled to lock or unlock the leaning part through the snap-fitting component.

[0005] If a child carrier is to realize the functions of adjusting the leaning part backward and folding the leaning part forward, two sets of adjustment mechanisms with different structures and independent operation are required to complete the function. Each set of adjustment mechanisms corresponds to its own engaging parts, controls the stroke of the corresponding engaging parts respectively, and realizes the functions of adjusting the leaning part backward and folding the leaning part forward independently. This will lead to a complex structure of the adjustment mechanism, inconvenient operation, and increased production costs.

[0006] Usually, a protective piece is also provided on the main load-bearing part, which not only makes the child in the carrier sit more stably, but also allows the child in the carrier to play, thus killing two birds with one stone. However, the problem that arises is that the protective piece needs to be folded when not in use, especially when the child carrier is folded, the protective piece needs to be folded first, and then the leaning part needs to be rotated and folded forward to fit the main load-bearing part, so that the entire child carrier is folded.

[0007] The protective part is usually installed on the main load-bearing part by a rotating connecting part. When it needs to be folded, the protective part is rotated to fit the main load-bearing part. The protective part does not have a one-button folding function, and cannot be automatically folded when the leaning part is folded forward. Especially when the child carrier is folded, the operator needs to perform multiple actions to complete the folding of the protective part and the leaning part. The operation is inconvenient and time-consuming and labor-intensive.

[0008] The side panels are usually mounted on the mounting parts by means of mounting shafts. After the mounting, the side panels cannot rotate around the mounting shafts, that is, the side panels cannot rotate relative to the mounting parts, which results in the volume of the child carrier being still relatively large after being folded.

[0009] The volume of a child carrier after folding directly affects the storage space. In particular, if the volume of the child carrier after folding can be further reduced, storage space can be saved, the carrying capacity of the child carrier can be increased, and transportation costs can be reduced.

[0010] In addition, the existing adjustment of the leaning part and the folding of the protective member are both controlled by independent mechanisms, which leads to a complex structure and inconvenient operation. Summary of the invention

[0011] One of the purposes of the present invention is to provide a control system which can synchronously drive the protective member and the side panel to work together when the leaning part is folded, and has a compact structure, saves space and is easy to operate.

[0012] The above-mentioned purpose of the present invention is achieved through the following technical scheme: a control system, including a leaning part adjustment device, characterized in that: the leaning part adjustment device is an adjustment device with a two-level stroke, which can adjust the leaning part with a two-level stroke; the control system also includes an automatic folding device for a protective member and a side panel stopping and rotation control device, and the two-level stroke adjustment device folds the leaning part while driving the automatic folding device for the protective member and the side panel stopping and rotation control device to operate, and when the leaning part is folded, the protective member and the side panel are synchronously driven to work in conjunction to realize the automatic folding of the protective member and the rotation of the side panel.

[0013] The existing leaning part adjustment and protective part folding are both controlled by independent mechanisms, which are complex in structure and inconvenient to operate. In the control system of the present invention, the leaning part adjustment device with a two-stage stroke not only serves as a leaning part adjustment device, but also serves as a trigger drive device for the protective part automatic folding device and the side panel stopping and rotation control device. When the leaning part adjustment operation is performed, the protective part automatic folding device and the side panel stopping and rotation control device are synchronously triggered to operate, thereby realizing the automatic folding of the protective part and the rotation of the side panel.

[0014] In the present invention, the adjustment device with two-stage stroke comprises an adjustment control unit, a clamping component, an adjustment groove and a folding groove. The adjustment control unit is installed on the leaning part of the child carrier, and the adjustment control unit is connected to the clamping component. The clamping component is inserted through the hinge seat at the bottom of the leaning part and extends out. The adjustment groove and the folding groove are both arranged on the side plate of the main bearing part of the child carrier and isolated from each other. The adjustment groove is built with a sliding block. The adjustment control unit can realize two-level stroke control of the clamping component. The control of the first-stage stroke is used to control the extending part of the clamping component to generate a first-stage stroke away from the side plate, and the The first-stage stroke generated makes the end face of the extension part between the end face and the bottom face of the adjusting groove; the control of the second-stage stroke controls the extension part of the engaging component to produce a second-stage stroke away from the side panel, and the second-stage stroke makes the end face of the extension part higher than the end faces of the adjusting groove and the folding groove, so that the leaning part can be folded forward, and when the leaning part is folded forward, the extension part pushes the sliding block to move, and the sliding block is respectively connected to the automatic folding device of the protective part and the side panel stopping and rotation control device, and when the sliding block moves, it drives the automatic folding device of the protective part and the side panel stopping and rotation control device to operate.

[0015] The adjustment device with two levels of stroke of the leaning part of the present invention can realize the control of the leaning part to adjust backward and fold forward. When the extension of the engaging part is disengaged from the corresponding adjustment groove, the leaning part is in an unlocked state. The first level of stroke makes the end face of the extension part between the groove end face and the groove bottom face of the adjustment groove, and makes the extension part contact with the groove wall when rotating to the extreme positions at both ends of the adjustment groove. The slot range of the adjustment groove limits the rotation adjustment angle of the leaning part, ensuring that the adjustment of the leaning part is safe and reliable.

[0016] The second-stage stroke makes the end face of the extension part higher than the end face of the adjusting groove, thereby increasing the adjustment stroke of the leaning part. When the leaning part rotates, the extension part is not restricted by the adjusting groove and can enter the folding groove from the adjusting groove. Through the control of the second-stage stroke, the leaning part can be rotated forward and folded, and when the folded position is converted into the adjustment position, the extension part can re-enter the adjustment groove from the folding groove.

[0017] When the adjustment operating unit releases the control of the engaging component, the extending portion of the engaging component will move in the direction close to the side panel; when the leaning part is in the adjustment position, the extending portion is located in the adjustment groove, and when the leaning part is rotated to the locking position, the extending portion is reinserted into the corresponding adjustment groove and locked; when the leaning part is in the folding position, the extending portion is located in the folding groove.

[0018] In the present invention, the sliding block is a sliding plastic block, which also has a return spring. One end of the return spring is fixed in the folding groove, and the other end is connected to the sliding plastic block. The sliding plastic block is an arc-shaped elastic member. When the folding leaning part is rotated forward, the protruding part located in the folding groove pushes the sliding plastic block. The return spring pushes the sliding plastic block to reset after the pushing force of the sliding plastic block is eliminated.

[0019] The invention adds a second-stage stroke to eliminate the displacement difference between the adjustment position and the folding position of the leaning part, thereby ensuring that the leaning part can be switched between the adjustment position and the folding position.

[0020] In the present invention, the hinge seat and the side plate are both arranged vertically, the extended portion of the engaging component is perpendicular to the hinge seat and the side plate, and the adjusting groove is arranged on the inner side of the side plate and close to the outer edge.

[0021] In the present invention, the adjustment groove and the folding groove are both arc-shaped grooves, the rotation centers of the adjustment groove, the folding groove, the hinge seat and the side panel coincide with each other, and the adjustment groove and the folding groove are located on the same circumference, and the groove end faces of the folding groove and the groove end faces of the adjustment groove form two steps; the leaning part is pulled backward for adjustment, and rotated forward for folding.

[0022] As an improvement of the present invention, after the sliding plastic block is built into the folding groove, a reserved groove area for the extension part to enter is left at one end close to the adjusting groove; one end of the return spring is fixed in the folding groove, and the other end is connected to the sliding plastic block; the sliding plastic block is an arc-shaped elastic part; when the folding leaning part is rotated forward, the extension part located in the folding groove pushes the sliding plastic block, and the sliding plastic block is deformed. The damping force generated can make the leaning part rotate and fold smoothly; the return spring pushes the sliding plastic block to reset after the pushing force of the sliding plastic block is eliminated.

[0023] In the present invention, a stop step is provided at the end of the folding groove in the retention groove area close to the sliding plastic block to limit the position of the sliding plastic block.

[0024] In the present invention, there are multiple adjustment grooves, the adjustment groove closest to the folding groove is a straight groove vertical to the side plate, and the other adjustment grooves are provided with transition slopes.

[0025] In the present invention, the automatic folding device of the protective element comprises an unlocking element, a positioning element and a folding element, the end of the unlocking element extends into the side panel of the main load-bearing part of the child carrier; the positioning element is located at the hinge where the protective element is hinged to the main load-bearing part, and is connected to the unlocking element, and the positioning element is inserted into the protective element when the protective element is in a locked state; the unlocking element is connected to the sliding block, and can drive the positioning element to move downward and disengage from the protective element under the action of the sliding block; the folding element is arranged at the hinge of the protective element, and the folding element is connected to the protective element, and is used to rotate the unlocked protective element to fit the main load-bearing part.

[0026] The automatic folding device of the protective member of the present invention is that when the positioning member is inserted into the protective member, the protective member is in a locked state, and when the positioning member moves downward to disengage from the protective member, the protective member is in an unlocked state. The state of the protective member is controlled by the positioning member, and the downward movement of the positioning member is controlled by the unlocking member. When the protective member needs to be unlocked, the unlocking member is driven by the sliding block to move, and then transmits force to the positioning member connected thereto, driving the positioning member to move downward to disengage from the protective member, so that the protective member is converted from a locked state to an unlocked state. When the protective member is in the unlocked state, the folding member drives the protective member to rotate, and rotates the unlocked protective member to fit the main bearing part, thereby realizing automatic folding of the protective member.

[0027] In the present invention, the unlocking member is a protective member stretching and pulling member, and the side panel is built with an arc-shaped sliding block, and the sliding block is a driving member of the unlocking member. The child carrier drives the engaging member through the operating unit to push the sliding block to rotate in a circular direction so that the leaning part can be folded forward; the end of the protective member stretching and pulling member is connected to the sliding block; when the sliding block moves, it drives the protective member stretching and pulling member to move downward, thereby driving the positioning member connected to the protective member stretching and pulling member to move downward and disengage from the protective member, so that the leaning part of the child carrier can be folded forward while the protective member can be automatically unlocked and folded backward simultaneously.

[0028] The present invention selects a rigid traction member with a simple structure as the unlocking member to facilitate the transmission of force. The driving member of the unlocking member is a sliding block built into the side panel of the child carrier. When the operator drives the engaging member through the operating unit to push the sliding block to rotate in a circular direction, the leaning part of the child carrier can be folded forward. At this time, the sliding block drives the protective member to pull the traction member to move downward during the rotation in the circumferential direction. The protective member pulls the traction member and then drives the positioning member to move downward and separate from the protective member, so that the protective member is folded toward the leaning part while the leaning part of the child carrier is folded forward. The folding action of the leaning part and the folding action of the protective member are performed simultaneously, and there is no need to perform other actions on the protective member.

[0029] As a preferred embodiment, the sliding block is a sliding plastic block, which is provided with a button hole, and the end of the protective member stretching and traction member has a button, which is inserted into the button hole, so that the end of the protective member stretching and traction member is buckled onto the sliding plastic block.

[0030] The sliding block can be a rigid block or a sliding plastic block with a certain elasticity. The sliding plastic block with elasticity makes the forward folding of the leaning part and the backward folding of the protective part gentler and will not hurt the operator accidentally. The protective part stretching traction part and the sliding plastic block adopt a buckle connection structure, which is simple, convenient and reliable.

[0031] In the present invention, the protective member stretching and pulling member is one, and the ends of both ends of the protective member stretching and pulling member are provided with buttons, and the sliding blocks are two, which are respectively arranged on the left and right sides of the child carrier, and the two buttons of the protective member stretching and pulling member are respectively inserted into the corresponding button holes. The protective member stretching and pulling member is driven by the two sliding blocks arranged on the left and right, which is beneficial to the balance of force and the stability of force transmission.

[0032] In the present invention, the main bearing part is provided with a protective seat, the protective member is hinged on the protective seat, the positioning member is built into the protective seat, and the lower end of the positioning member is connected to the protective member stretching and traction member; the folding member is also installed on the protective seat.

[0033] In the present invention, the positioning piece is a positioning particle, and a card hole is provided at the lower end of the positioning particle for clamping the protective piece stretching and traction piece; a locking recess adapted to the positioning particle is provided at the lower part of the protective piece, and the locking or unlocking of the protective piece is achieved by inserting the positioning particle upward or disengaging it downward from the locking recess.

[0034] In the present invention, the middle rope segment of the protective member stretching and pulling member is a spiral rope segment, and the spiral rope segment is clamped with the clamping hole.

[0035] In the present invention, the positioning particle further comprises a return spring, the bottom end of the return spring is fixedly mounted in the handle seat, and the top end is fixedly connected to the bottom end of the positioning particle.

[0036] In the present invention, the folding member is a torsion spring, the fixed end of the torsion spring is fixedly connected to the handle seat, and the rotating end of the torsion spring is fixedly connected to the protective member.

[0037] In the present invention, the side panel stopping and rotation control device comprises a seat panel linkage block, a linkage elastic member and a seat panel rotating shaft, the seat panel rotating shaft is fixedly mounted on the mounting part of the child carrier, the side panel of the child carrier has a rotating shaft hole adapted to the seat panel rotating shaft, the rotating shaft hole is fitted on the seat panel rotating shaft; the cross-sections of the rotating shaft hole and the seat panel rotating shaft are both circular notch surfaces with a flat bottom surface; the seat panel linkage block and the linkage elastic member are both built-in into the side panel, the linkage elastic member is located in front of the seat panel linkage block, and the front and rear ends of the linkage elastic member are respectively connected to the side panel and the seat panel linkage block; the top surface of the seat panel linkage block is a plane with a circular notch concave surface; the seat panel linkage block is connected to the sliding block, and can move under the action of the sliding block so that the circular notch concave surface is aligned or staggered with the rotating shaft hole; thereby controlling the stopping of the side panel or the rotation relative to the mounting part.

[0038] In the side panel stop and rotation control device of the present invention, the side panel of the child carrier is installed on the seat plate rotating shaft of the mounting member through the rotating shaft hole, the cross section of the rotating shaft hole and the seat plate rotating shaft are both circular notch surfaces with a flat bottom surface, the side panel is built with a seat plate linkage block, the top surface of the seat plate linkage block is a plane with a circular notch concave surface, the seat plate linkage block can move under the action of external force, and the stop of the side panel or the rotation relative to the mounting member is controlled by the different states of the circular notch concave surface being aligned or intersected with the rotating shaft hole. When the seat plate linkage block moves to the circular notch concave surface to align with the rotating shaft hole, a complete circular surface is formed, and at this time the side panel is in a rotation position that can rotate relative to the mounting member, which can reduce the volume of the child carrier after folding; when the circular notch concave surface intersects with the rotating shaft hole, the side panel is in a stop position, and the side panel cannot rotate around the seat plate rotating shaft.

[0039] In the present invention, the sliding block is a sliding plastic block, which has a wedge-shaped groove. The seat plate linkage block is a plastic block, and the end of the seat plate linkage block has a wedge-shaped protrusion that is compatible with the wedge-shaped groove. When the leaning part is in an upright use state, the protrusion of the seat plate linkage block is inserted into the concave part of the sliding block. When the leaning part is folded forward, the sliding plastic block pushes the seat plate linkage block to move in the direction toward the linkage elastic part, so that the circular concave surface is aligned with the rotating shaft hole.

[0040] When the operator drives the engaging part through the operating unit to push the sliding block to rotate in the circumferential direction, the leaning part of the child carrier can be folded forward. At this time, the sliding block pushes the seat plate linkage block to move during the rotation in the circumferential direction, so that the concave surface of the circular notch is aligned with the shaft hole, and the side plate is converted from the rotation position to the rotation position, so that the side plate can still rotate relative to the mounting part after the child carrier is folded, thereby further reducing the volume of the child carrier after folding.

[0041] The sliding block can be a rigid block or a sliding plastic block with a certain elasticity. The sliding plastic block with elasticity makes the forward folding of the leaning part gentler and will not accidentally injure the operator. The connection structure between the sliding plastic block and the seat plate linkage block adopts a wedge-shaped protrusion and a wedge-shaped groove, which is simple and convenient and facilitates the seat plate linkage block to move when the sliding plastic block rotates.

[0042] In the present invention, the linkage elastic member is a linkage spring.

[0043] In the present invention, the side plate has a straight-line accommodating groove for accommodating a seat plate linkage block and a linkage spring, the accommodating groove is arranged along the axial direction of the child carrier, the seat plate linkage block and the linkage spring are both arranged in a straight line along the axial direction of the child carrier, and the seat plate linkage block moves along the length direction of the accommodating groove under the thrust of the sliding block.

[0044] In the present invention, a seat plate fixing cover is installed on the inner side of the side plate, and the seat plate fixing cover seals the accommodating groove and plays a limiting and guiding role for the seat plate linkage block and the linkage spring in the accommodating groove.

[0045] In the present invention, the seat plate rotation axis is perpendicular to the mounting member, which is convenient for mounting the side plate.

[0046] In the present invention, the adjustment control unit is a two-stage travel control structure of a manually controlled traction member, comprising a limit edge, an operating member, a traction member, and an adjustment button, wherein one end of the operating member is a hinged end, and the other end is a free end, and the adjustment button is arranged on the operating member and can reciprocate along the operating member between the hinged end and the free end of the operating member, wherein the limit position of the adjustment button close to the hinged end of the operating member is the action position of the adjustment button, and the limit position of the adjustment button far from the hinged end of the operating member is the non-action position of the adjustment button; the limit edge is in the action position The adjusting button is arranged in a path along which the operating member rotates, one end of the traction member is connected to the operating member and is displaced along with the rotation of the operating member; the end surfaces of the adjusting button and the operating member facing the limiting edge are their respective action surfaces, and the action surface of the adjusting button protrudes from the action surface of the operating member; the adjusting button at the action position rotates along with the operating member until the action surface of the adjusting button abuts against the limiting edge, so that the traction member generates a first-stage displacement, and the adjusting button at the non-action position rotates along with the operating member until the action surface of the operating member abuts against the limiting edge, so that the traction member generates a second-stage displacement.

[0047] The rotation limit amplitude of the operating member is changed by adjusting the button position, thereby realizing a multi-stage stroke of the traction member whose displacement is limited by the rotation amplitude of the operating member. When the adjustment button is in the working position, the adjustment button with a higher action surface will eventually abut against the limit edge during the rotation of the operating member. At this time, the rotation limit amplitude of the operating member is small, and the displacement of the traction member is correspondingly small. This is the first stage stroke of the traction member. When the adjustment button is in the non-working position, the action surface of the operating member directly abuts against the limit edge. At this time, the rotation limit amplitude of the operating member is large, and the displacement of the traction member is correspondingly large. This is the second stage stroke of the traction member.

[0048] The adjustment control unit of the present invention further includes a return spring, the two ends of which are respectively connected to the operating member and the adjustment button, and the return spring keeps the adjustment button in the action position of the adjustment button. The user can directly rotate the operating member of this embodiment to make the traction member produce a primary stroke; the user applies force to overcome the return spring to move the adjustment button from the action position to the non-action position, and at this time, rotating the operating member can make the traction member produce a secondary stroke. After the external force is removed, the adjustment button returns to its position under the action of the return spring.

[0049] In the present invention, the operating member is hinged on the leaning part through a latch pin, and the latch pin is the hinge axis of the operating member; the bottom end of the traction member gradually transitions by 90°, and the pulling force generated by the operating member pulling the traction member is bent by 90° and becomes an inward lateral pulling force away from the side panel along the width direction of the leaning part.

[0050] In the present invention, the traction member, the engaging member, the adjusting groove and the folding groove are all in two sets, which are arranged in a bilaterally symmetrical manner with the central axis of the child carrier as the center.

[0051] In the present invention, the engaging component is an L-shaped engaging component, including a bottom rod arranged along the width direction of the leaning part and a straight rod arranged perpendicular to the leaning part, the bottom rod is located in a receiving groove opened along the width direction of the leaning part, and is sealed by a fixed cover, the protruding part is a bolt column, the protruding part is vertically connected to the straight rod, the protruding part is inserted into the guide hole opened on the hinge seat and protrudes, the guide hole is perpendicular to the hinge seat, the bottom rod of the engaging component is connected to the adjusting and operating unit, and the bottom rod is pulled by the adjusting and operating unit to finally drive the protruding part to move axially along the guide hole.

[0052] In the present invention, the engaging member is an elastic restoring iron support, and the engaging member has an engaging spring, one end of which is connected to the bottom rod of the engaging member, and the other end is connected to the leaning part, for resetting the engaging member.

[0053] A second object of the present invention is to provide a child carrier that can not only improve the comfort of the child but also save space and facilitate storage.

[0054] This object of the present invention is achieved through the following technical solution: a child carrier including the above-mentioned control system, characterized in that: the child carrier also includes a main load-bearing part and a leaning part, the frame is supported on the wheels, the main load-bearing part is installed on the frame, the main load-bearing part has a side panel, the leaning part has a hinge seat, the hinge seat is hinged to the side panel, the child carrier controls the leaning part to fold through the control system, and when the leaning part is folded, the protective part and the side panel are synchronously driven to work together.

The leaning part adjustment device folds the leaning part while driving the automatic folding device of the protective member and the side panel stop and rotation control device to operate, and when the leaning part is folded, the protective member and the side panel are synchronously driven to be linked, so as to achieve automatic folding of the protective member and rotation of the side panel. The child carrier controls the folding of the leaning part through the control system, and when the leaning part is folded, the protective member and the side panel are synchronously driven to be linked.

[0089] The adjustment device with two-stage stroke of the leaning part of the present embodiment comprises an adjustment operating unit, a clamping component, an adjustment groove 8a and a folding groove 8d. The adjustment operating unit is mounted on the leaning part 1 of the child carrier, and the adjustment operating unit is connected to the clamping component. The clamping component is inserted through the hinge seat 1a at the bottom of the leaning part 1 and extends out. The adjustment groove 8a and the folding groove 8d are both provided on the side panel 8 of the main load-bearing part 101 of the child carrier and are isolated from each other. The folding groove 8d is located at the front and the adjustment groove 8a is located at the rear. The side panel 8 is used to be hinged with the hinge seat 1a. The hinge axis of the two is a rivet 7. The protruding portion of the clamping component extending out of the hinge seat 1a is located within the slotted range of the adjustment groove 8a.

[0090] In this embodiment, the engaging component is an L-shaped engaging member 5, including a bottom rod 51 arranged along the width direction of the leaning portion 1 and a straight rod 52 arranged perpendicular to the leaning portion 1. The bottom rod 51 is located in a receiving groove 1c opened along the width direction of the leaning portion 1 and is sealed by a fixed cover 4. The fixed cover 4 is installed on the leaning portion 1 by screws 2. The protruding portion is a bolt column 53, which is vertically connected to the straight rod 52. The protruding portion is inserted into a guide hole 1b opened on the hinge seat 1a and protrudes out. The guide hole 1b is perpendicular to the hinge seat 1a. The bottom rod 51 of the engaging member 5 is connected to the adjustment operating unit. Pulling the bottom rod 51 by the adjustment operating unit ultimately drives the protruding portion to move axially along the guide hole 1b.

[0091] The engaging member 5 in this embodiment is an elastic restoring member, and has an engaging spring 6 , one end of which is connected to the bottom rod 51 of the engaging member 5 , and the other end of which is connected to the leaning part 1 , for resetting the engaging member 5 .

[0092] In this embodiment, the hinge seat 1a and the side panel 8 are both vertically arranged, the hinge seat 1a is a circular seat, the side panel 8 is a circular plate, the protruding portion of the engaging component is perpendicular to the hinge seat 1a and the side panel 8, the adjusting groove 8a is opened on the inner side of the side panel 8 and close to the outer edge, the adjusting groove 8a and the folding groove 8d are both arc-shaped grooves, the centers of the adjusting groove 8a, the folding groove 8d, the hinge seat 1a and the side panel 8 coincide, and the adjusting groove 8a and the folding groove 8d are located on the same circumference, and the groove end surface of the folding groove 8d forms two steps with the groove end surface of the adjusting groove 8a; there are multiple adjusting grooves 8a, the adjusting groove 8a closest to the folding groove 8d is a straight groove vertical to the side panel 8, and the remaining adjusting grooves 8a are provided with transition slopes.

[0093] As a preferred embodiment, the folding groove 8d also accommodates a sliding plastic block 11 and a return spring 12. The sliding plastic block 11 serves as a sliding block and also has the function of a damper. After the sliding plastic block 11 is built into the folding groove 8d, a reserved groove area 8e is reserved for the extension part to enter at one end close to the adjusting groove 8a. The folding groove 8d is provided with a stop step 8f at the end of the reserved groove area 8e close to the sliding plastic block 11 to limit the position of the sliding plastic block 11. One end of the return spring 12 is fixed in the folding groove 8d, and the other end is connected to the sliding plastic block 11. The sliding plastic block 11 is an arc-shaped elastic member. When the folding leaning part is rotated forward, the protruding part located in the folding groove 8d pushes the sliding plastic block 11, and the sliding plastic block 11 is deformed. The damping force generated can make the leaning part rotate and fold smoothly, and the return spring 12 pushes the sliding plastic block 11 to reset after the pushing force of the sliding plastic block 11 is eliminated.

[0094] In this embodiment, the adjustment control unit can realize two-level stroke control of the engaging component. The control of the first-level stroke is used to control the extension of the engaging component to move in a direction away from the side plate 8, and to disengage from the adjustment groove 8a, thereby generating a first-level stroke away from the side plate 8. After the extension is disengaged from the adjustment groove 8a, the leaning part 1 is in an unlocked state, and the leaning part can be rotated to adjust the leaning part, and the generated first-level stroke makes the end surface of the extension part between the groove end surface and the groove bottom surface of the adjustment groove 8a, such as Fig.12 As shown, when the extension part rotates to the extreme positions at both ends of the adjustment groove 8a, it conflicts with the groove wall. The groove range of the adjustment groove 8a limits the rotation adjustment angle of the leaning part, ensuring that the leaning part is adjusted safely and reliably.

[0095] The control of the secondary stroke controls the extension of the engaging part to continue to move in the direction away from the side plate 8 on the basis of the control of the first stroke, thereby generating a second stroke away from the side plate 8. The increase of the second stroke eliminates the displacement difference between the adjustment position and the folding position of the leaning part, thereby ensuring that the leaning part can be switched between the adjustment position and the folding position. The second stroke makes the end surface of the extension higher than the end surface of the adjustment groove 8a and the folding groove 8d. Fig.13As shown in FIG. 1 , when the leaning part rotates, the extension portion is not restricted by the adjustment groove 8a and the folding groove 8d and can enter the folding groove 8d. When the extension portion of the engaging part enters the folding groove 8d, as shown in FIG. Fig.15 As shown, the control of the clamping part by the adjusting control unit is released, and the leaning part is rotated at this time, and the extension of the clamping part will push the sliding plastic block 11 and the return spring 12, so that the leaning part can be rotated forward and folded. When the leaning part needs to be converted from the folding position to the adjustment position, the clamping part is controlled by the adjusting control unit again, so that the end face of the extension of the clamping part is higher than the end face of the folding groove 8d and the adjustment groove 8a, and the folding groove 8d will not hinder the extension of the clamping part when the leaning part rotates. When the leaning part rotates from the folding position to the adjustment position, the control of the clamping part by the adjusting control unit is released, and the extension of the clamping part re-enters the adjustment groove 8a. After the adjusting control unit releases the control of the clamping part, the leaning part is rotated, and the extension of the clamping part will move in the direction close to the side plate 8; when the leaning part is in the adjustment position, the extension is located in the adjustment groove 8a, and when the leaning part is rotated to the locking position, the extension is reinserted into the corresponding adjustment groove 8a and locked; when the leaning part is in the folding position, the extension is located in the folding groove 8d. The first and second strokes of the extended portion of the engaging component away from the side panel 8 are controlled by the adjustment and operation unit. The sliding plastic block 11 is connected to the automatic folding device of the guard and the side panel stop and rotation control device respectively. When the sliding plastic block 11 moves, the automatic folding device of the guard and the side panel stop and rotation control device are driven to operate.

The end faces of the position edge 9a are their respective action surfaces, and the action surface of the adjustment button 13 protrudes from the action surface of the operating member 9; the adjustment button 13 at the action position rotates with the operating member 9 until the action surface of the adjustment button 13 abuts against the position-limiting edge 9a, so that the traction member 3 produces a first-stage displacement; the adjustment button 13 at the non-action position rotates with the operating member 9 until the action surface of the operating member 9 abuts against the position-limiting edge 9a, so that the traction member 3 produces a second-stage displacement; the two ends of the return spring 14 are respectively connected to the operating member 9 and the adjustment button 13, and the return spring 14 keeps the adjustment button 13 at the action position of the adjustment button 13. The bottom end of the traction member 3 is bent at an angle of 90°, and the pulling force generated by the operating member 9 pulling the traction member 3 is converted into an inward lateral pulling force away from the side plate 8 along the width direction of the leaning part 1 after being bent by 90°.

The operating member 9 pulls the traction member 3 to generate an upward pulling force along the length direction of the leaning part 1, which is bent by 90° and then becomes an inward lateral pulling force away from the side plate 8 along the width direction of the leaning part 1.

[0099] The adjustment button 13 is used to control the second-stage travel of the extension part. When the adjustment button 13 is pulled upward relative to the operating member 9, the traction member 3 is pulled to move synchronously during the movement of the adjustment button 13, and then the extension part of the engaging part is further moved to generate a second-stage travel away from the side plate 8. Fig.18 As shown, the return spring 14 is compressed at this time; the return spring 14 is used to pull the adjustment button 13 back to the initial position after the external force is eliminated.

The child carrier drives the engaging member 5 through the operating unit to push the sliding block to rotate in a circular direction so that the leaning part 1 can be folded forward; the end of the protective member stretching and pulling member 17 is connected to the sliding block; when the sliding block moves, it drives the protective member stretching and pulling member 17 to move downward, thereby driving the positioning member connected to the protective member stretching and pulling member 17 to move downward and disengage from the protective member 19, so that the leaning part 1 of the child carrier can be folded forward while the protective member 19 can be automatically unlocked and folded backward at the same time.

[0102] In this embodiment, the sliding block is a sliding plastic block 11, and the sliding plastic block 11 is provided with a button hole 111. The end of the protective member stretching and pulling member 17 has a button 171, and the button 171 is inserted into the button hole 111, so that the end of the protective member stretching and pulling member 17 is buckled on the sliding plastic block 11.

The sliding block is two, which are respectively arranged on the left and right sides of the child carrier, and the two buttons 171 of the protective member stretching and pulling member 17 are respectively inserted into the corresponding button holes 111.

[0103] In this embodiment, the main bearing part 101 is provided with a protective seat 18, and the protective member 19 is hinged on the protective seat 18 by a rivet 20.

The positioning member is built into the protective seat 18, and the lower end of the positioning member is connected to the protective member stretching and traction member 17; the folding member is also installed on the protective seat 18.

[0104] The positioning piece is a positioning particle 15, and a card hole 151 is provided at the lower end of the positioning particle 15 for clamping the protective piece stretching traction piece 17; a locking recess adapted to the positioning particle 15 is provided at the lower part of the protective piece 19, and the locking or unlocking of the protective piece 19 is achieved by inserting the positioning particle 15 upward or disengaging it downward from the locking recess.

[0105] As a preferred implementation scheme, the middle rope segment of the protective member stretching traction member 17 is a spiral rope segment 172, and the spiral rope segment 172 is clamped with the clamping hole 151.

[0108] In the automatic folding device for protective members of the present invention, when the positioning particle 15 is inserted into the protective member 19, the protective member 19 is in a locked state, and when the positioning particle 15 moves downward to disengage from the protective member 19, the protective member 19 is in an unlocked state. The state of the protective member 19 is controlled by the positioning particle 15, and the downward movement of the positioning particle 15 is controlled by the protective member stretching traction member 17. The rotation of the protective member 19 after unlocking is controlled by the torsion spring 21.

[0109] The side panel stop and rotation control device of the present embodiment includes a seat panel linkage block 23, a linkage elastic member and a seat panel shaft 221. The seat panel shaft 221 is fixedly mounted on the mounting member 22 of the child carrier, and the seat panel shaft 221 is perpendicular to the mounting member 22. The side panel 8 of the child carrier has a shaft hole 81 adapted to the seat panel shaft 221. The shaft hole 81 is fitted with the seat panel shaft 221, so that the side panel 8 is mounted on the mounting member 22. The cross-sections of the shaft hole 81 and the seat panel shaft 221 are both circular notches with a flat bottom surface. The seat panel linkage block 23 and the linkage elastic member are both built into the side panel 8. The linkage elastic member is located in front of the seat panel linkage block 23. The front and rear ends of the dynamic elastic member are respectively connected to the side panel 8 and the seat panel linkage block 23; the top surface of the seat panel linkage block 23 is a plane with a circular concave surface 231; the seat panel linkage block 23 can move under the action of external force, so that the circular concave surface 231 is aligned with or intersected with the shaft hole 81. When the circular concave surface 231 is aligned with the shaft hole 81, a complete circular surface is formed. At this time, the side panel 8 is in a rotating position and can rotate around the seat panel shaft 221 to reduce the volume of the child carrier after folding; when the circular concave surface 231 is intersected with the shaft hole 81, the side panel 8 is in a stopped position; thereby controlling the stopping of the side panel 8 or the rotation relative to the mounting member 22.

[0110] In this embodiment, the central angle corresponding to the circular segment surface of the shaft hole 81 is α; the central angle corresponding to the circular segment concave surface 231 is β. The angle values ​​of α and β can be selected according to actual needs, α+β=360°.

[0111] In this embodiment, an arc-shaped sliding block is built into the side panel 8, and the sliding block is a driving member of the seat panel linkage block 23. The sliding block has a recessed portion. The child carrier drives the engaging member 5 through the operating unit to push the sliding block to rotate in the circumferential direction so that the leaning part 1 can be folded forward; the end of the seat panel linkage block 23 has a convex portion adapted to the concave portion of the sliding block. When the leaning part 1 is in an upright use state, the convex portion of the seat panel linkage block 23 is inserted into the concave portion of the sliding block. When the sliding block rotates in the circumferential direction and the leaning part 1 is folded forward, the sliding block pushes the seat panel linkage block 23 to move in the direction toward the linkage elastic member, so that the circular concave surface 231 is aligned with the shaft hole 81, so that after the leaning part 1 of the child carrier is folded forward, the side panel 8 can also rotate relative to the mounting member 22, thereby further reducing the volume of the child carrier after folding.

[0112] As a preferred implementation scheme, the sliding block is a sliding plastic block 11, the recess is a wedge-shaped groove 111, the seat plate linkage block 23 is a plastic block, the convex part of the seat plate linkage block 23 is a wedge-shaped protrusion 232 adapted to the wedge-shaped groove 111; the linkage elastic member is a linkage spring 24.

[0113] In this embodiment, the side plate 8 has a straight-shaped receiving groove 82 for receiving the seat plate linkage block 23 and the linkage spring 24. The receiving groove 82 is arranged along the axial direction of the child carrier. The side plate 8 is provided with a seat plate fixing cover 27 on the inner side. The seat plate fixing cover 27 covers the receiving groove 82. The seat plate linkage block 23 and the linkage spring 24 are both arranged in a straight line along the axial direction of the child carrier. The seat plate linkage block 23 moves along the length direction of the receiving groove 82 under the thrust of the sliding block. The mounting member 22 is a plastic member, and a quick release button 25 and a button spring 26 are also arranged on the mounting member 22.

[0114] In the side panel stop and rotation control device of the present invention, the side panel 8 of the child carrier is mounted on the seat panel rotation axis 221 of the mounting member 22 through the rotation axis hole 81. The cross-sections of the rotation axis hole 81 and the seat panel rotation axis 221 are both circular segment surfaces with a flat bottom surface, and the top surface of the seat panel linkage block 23 of the side panel 8 is a plane with a circular segment concave surface 231. The seat panel linkage block 23 can move under the action of external force, and the stop of the side panel 8 or the rotation relative to the mounting member 22 is controlled by different states of the circular segment concave surface 231 being aligned or interlaced with the rotation axis hole 81.

[0115] The specific operation process of the child carrier of the present invention controlling each device through the control system is as follows:

[0116] like Figures 2 to 5The leaning portion shown is in an upright state, at this time, the protruding portion of the engaging component is inserted into the corresponding adjustment groove 8a; the protective member 19 is in an upright locked state, the positioning particle 15 is inserted into the protective member 19, and the torsion spring 21 has a torsional force on the protective member 19, but due to the insertion restriction of the positioning particle 15, the protective member 19 cannot rotate; at this time, the operator does not operate the unit to apply a driving force to the bolt 53 of the engaging member 5, the sliding plastic block 11 is not pushed by the bolt 53, and the return spring 12 is in an uncompressed state; the wedge-shaped protrusion 232 of the seat plate linkage block 23 is located in the wedge-shaped groove 11 of the sliding plastic block 11, the circular concave surface 231 is staggered with the shaft hole 81, the side plate 8 is in a stop position, and the side plate 8 cannot rotate around the seat plate shaft 221.

[0117] When the operating member 9 is used to control the first level of the leaning portion, the state of the leaning portion after being adjusted backward is as shown in the figure. Figure 6 shown.

[0118] When the adjustment button 13 is further used to control the second level of the leaning part, the leaning part can be folded forward. The folding process is as follows: Figure 24 to Figure 27 As shown; at this time, the sliding plastic block 11 drives the protective member pulling and pulling member 17 to move downward during the process of rotating in the circumferential direction, and the protective member pulling and pulling member 17 then drives the positioning particle 15 to move downward and disengage from the protective member 19, and at the same time presses down the return spring 16, so that the protective member 19 is converted from a locked state to an unlocked state. When the protective member 19 is in the unlocked state, the torsion spring 21 releases the torque, rotates the protective member 19, and rotates and folds the unlocked protective member 19, that is, when the leaning part of the child carrier is folded forward, the protective member 19 is folded backward toward the leaning part, and the folding action of the leaning part and the folding action of the protective member 19 are performed synchronously, and no other action is required for the protective member 19. At the same time, the sliding plastic block 11 drives the seat plate linkage block 23 to move along the length direction of the accommodating groove 82 during the process of rotating in the circumferential direction, compresses the linkage spring 24, and the seat plate linkage block 23 moves to the circular concave surface 231 and is aligned with the shaft hole 81, forming a complete circular surface, and the side plate 8 is in a rotating position relative to the mounting member 22.

[0119] The state diagram after the leaning part is folded is as follows Figure 28 to Figure 31As shown. At this time, the protective member 19 rotates to the limit position that fits the main load-bearing part. At this time, the sliding plastic block 11 is also in the limit position pushed by the bolt column 53, and the return spring 12 is in the limit compression state. The entire child carrier is in a completely folded state. At the same time, when the leaning part is folded forward to the limit position that fits the main load-bearing part, the circular concave surface 231 of the seat plate linkage block 23 is still aligned with the shaft hole 81, and the side panel 8 is in a rotational position that can rotate relative to the mounting member 22. That is, during the entire process of the leaning part being folded forward, the circular concave surface 231 of the seat plate linkage block 23 is always kept aligned with the shaft hole 81, and the side panel 8 is in a rotational position that can rotate relative to the mounting member 22. After the leaning part is folded forward to the limit position that fits the main load-bearing part, the side panel 8 can be further rotated relative to the mounting member 22 to further reduce the volume of the child carrier after folding. The structure of the child carrier after it is finally folded is shown as follows. Fig.32 shown.

[0120] When the child carrier is unfolded, the adjustment device with a two-stage stroke of the leaning part controls the bolt 53 of the engaging member 5 to rotate in the opposite direction in the circumferential direction, and the external force applied by the bolt 53 to the sliding plastic block 11 is eliminated. At this time, the sliding plastic block 11 also rotates in the opposite direction in the circumferential direction under the elastic restoring force of the return spring 12. When the sliding plastic block 11 rotates in the opposite direction, it simultaneously drives the protective member and the side panel to move in conjunction.

[0121] When the sliding plastic block 11 rotates in the opposite direction along the circumferential direction, it drives the protective member stretching and pulling member 17 to move upward. The operator pulls the protective member 19 to rotate from the position of being in contact with the main load-bearing part to the direction away from the leaning part. During the pulling process, the torsion spring 21 accumulates torque. When the protective member 19 rotates to an upright state, the positioning particle 15 is aligned with the locking recess provided in the protective member 19. Under the joint action of the protective member stretching and pulling member 17 and the return spring 16, the positioning particle 15 moves upward into the locking recess, and the protective member 19 is reinserted. The protective member 19 is again converted from the unlocked state to the locked state as shown in the figure. Figure 2 Lock status shown.

[0122] While the sliding plastic block 11 rotates in the reverse direction along the circumferential direction, when the sliding plastic block 11 rotates until the wedge-shaped groove 11 is aligned with the wedge-shaped protrusion 232 of the seat plate linkage block 23, the linkage spring 24 pushes the seat plate linkage block 23 to move in the reverse direction along the length direction of the accommodating groove 82, and the wedge-shaped protrusion 232 of the seat plate linkage block 23 is located in the wedge-shaped groove 11 of the sliding plastic block 11 again. At this time, the circular concave surface 231 is staggered with the shaft hole 81, and the side plate 8 is again converted from the rotation position relative to the mounting member 22 to the position as shown in the figure. Figure 2 Detent position shown.
