[0107] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0108] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be an intermediate component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be an intermediate component.

[0109] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0110] See also Figure 1a and Figure 1b Some embodiments of the present application provide a control device comprising: a telescopic structure 100, a sliding lock 2100, a control member 300, and a first traction cable 4100. The telescopic structure 100 comprises a first component and a second component that slidably engage with each other. The sliding lock is used to limit the relative position of the first and second components. The control member is movably disposed within the first component and can act on a controlled component 500 when it moves. The second component is always adjacent to at least a portion of the control member within its sliding travel. The first traction cable 4100 extends within the second component and engages with a releasable transmission of the control member.

[0111] In this embodiment, the first component and the second component are hollow rods as an example, wherein the first component is the outer rod 1200 and the second component is the inner rod 1100 .

[0112] The first and second components may be connected by a sliding connection, and the sliding path may be either linear or curved. Adjacent means that the control component and the second component are in contact and linkage, or in sliding contact. For example, in this embodiment, the control component is rod-shaped. When the inner rod slides relative to the outer rod, it always slides in contact with the inner wall of the inner rod.

[0113] The first traction rope 4100 slides and moves synchronously with the second component. One end of the first traction rope 4100 has a transmission relationship with the control component, and the transmission relationship can be selectively connected or disconnected.

[0114] When the first component and the second component move relative to each other, the second traction rope can be used to transmit the signal to the sliding lock to release the lock. The controlled component can be one, and the control component directly or indirectly acts on the controlled component, such as changing the motion or static state, maintaining or releasing motion interference.

[0115] There may be two or more controlled components, and the control element may act directly or indirectly on one of the controlled components.

[0116] In addition, the control member also serves as an indicator member alone, that is, there is no controlled component, and the control member can be used to indicate a position or state related to the telescopic structure 100.

[0117] For example, in another embodiment, the control device includes: a telescopic structure 100, a sliding lock, a control member, and a first traction cable 4100. The telescopic structure 100 includes a first component and a second component that slide together. The sliding lock is used to limit the relative position of the first component and the second component. The control member is movably disposed within the first component and can correspond to or indicate different states when it moves. The first traction cable 4100 extends within the second component and engages with a releasable transmission of the control member.

[0118] The inner rod 1100 and outer rod 1200 mentioned in this application can be hollow tubes or have chambers or channels defined in at least predetermined areas, depending on the requirements for mounting other components and avoiding interference. The inner rod 1100 and outer rod 1200 can be straight or have a certain degree of curvature. There are no strict restrictions on their cross-sectional shapes. The inner rod 1100 and outer rod 1200 can be at least partially nested within each other, for example, with a portion of the inner rod inserted within the outer rod. However, the nested portion does not strictly limit the outer rod to completely surrounding the inner rod; it can also partially surround the inner rod.

[0119] Another embodiment of the present application provides a control device, which is a control device based on a controlled component of the telescopic structure 100 , including: the telescopic structure 100 , a sliding locking mechanism, a control member 300 , and a first unlocking member 4200 .

[0120] The telescopic structure 100 includes an inner rod and an outer rod that slide and nest together. A sliding locking mechanism acts between the inner rod 1100 and the outer rod 1200. The control member 300 is rod-shaped and slides within the outer rod 1200. One end of the control member 300 acts on the controlled component 500. At least two linkage structures 3100 are spaced apart on the control member 300. There are four linkage structures 3100 in the figure, each of which is a coupling groove. The first unlocking member 4200 in the figure is coupled to the leftmost one. The first unlocking member 4200 is movably mounted on the inner rod 1100 and couples with the corresponding linkage structures 3100 to drive the control member.

[0121] The control member 300 is used to lock the controlled member 500. The control member can lock the controlled member directly or indirectly through a transmission mechanism. This embodiment can also be combined with other embodiments herein. For example, based on the configuration of multiple linkage structures 3100, the inner rod maintains sliding contact with the control member throughout its sliding travel.

[0122] The multiple linkage structures can make the operation of the control member 300 more flexible, and do not strictly limit the position of the inner rod during linkage or the deformation process of the telescopic structure. During the deformation process of the telescopic structure, the linkage can be implemented and the control member can be operated in a timely manner.

[0123] Some embodiments of the present application provide a self-expandable control device for locking or unlocking a controlled component, the control device comprising: an outer rod 1200, an inner rod 1100, a sliding lock 2100, a control member 300, and a first unlocking member 4200.

[0124] The outer rod has a cavity 1210 inside, one end of the inner rod is outside the outer rod, and the other end is a connecting section that is slidably inserted into the cavity.

[0125] A sliding lock 2100 is mounted on the connecting section and is used to lock or unlock the relative position of the inner and outer rods. The control member 300 has a working head at one end for locking the controlled component 500 and a coupling section at the other end. The coupling section slides through the inner rod or through the radial gap between the inner and outer rods, and is equipped with at least two linkage structures 3100. A first unlocking member 4200 is movably mounted on the connecting section and has an idle position and an active position relative to the connecting section. In the idle position, it avoids the extension path of the coupling section. In the active position, it can couple with the corresponding linkage structure as the inner rod moves to drive the control member to unlock the controlled component.

[0126] The working head directly locks the controlled component or indirectly locks the controlled component by transmission.

[0127] Reference Figure 2 and Figure 10 , Figure 2 The first unlocking member 4200 is partially located in the coupling groove, and the first unlocking member 4200 is in the working position; Figure 10 The first unlocking member 4200 is disengaged from the coupling groove, and the first unlocking member 4200 is in an unloaded position.

[0128] The first unlocking member 4200 avoids the extension path of the coupling section in the no-load position, that is, no matter where the inner rod moves to, even if it is opposite to the coupling groove position, it does not enter the coupling groove. In addition, due to the extension path of the avoidance coupling section, it will not interfere with the control member 300 when moving with the inner rod.

[0129] In combination with the above embodiments, since the control member is always adjacent to the inner rod, it is convenient to configure multiple linkage structures and to achieve linkage as needed when the telescopic structure is deformed.

[0130] Reference Figures 1a to 12 As for the principle and structural characteristics of the sliding locking mechanism itself, the existing ones can be adopted, which is not the focus of improvement of this application. This application also provides an improved solution in the shape structure of the linkage or mutual cooperation part between it and the first unlocking member.

[0131] The sliding locking mechanism includes a sliding locking member 2100 and a second unlocking member 2200. The sliding locking member 2100 radially passes through the outer rod 1200 and inner rod 1100 to unlock and lock both, thereby restricting their relative position. To facilitate locking, a locking hole 1220 can be provided in the outer rod 1200, and a corresponding clearance hole can be provided in the inner rod as needed to allow the sliding locking member to pass through.

[0132] In order to control the sliding lock, the sliding locking mechanism further includes a second unlocking member 2200, which is connected to the second operating member 2300 via a second traction rope 2400. The second traction rope 2400 can be extended in the inner rod 1100 in the form of a metal wire or the like and is convenient for steering.

[0133] The second unlocking member 2200 is slidably mounted within the inner rod 1100. The second unlocking member defines a drive hole 2210 that is arranged obliquely relative to its own sliding path. The sliding locking member 2100 is a locking pin and has a second linkage portion 2110 that extends into the drive hole 2210 (the second linkage portion 2110 can be in the form of a rod, etc.).

[0134] When locking, the locking pin extends out of the inner rod 1100 and enters the locking hole to lock the relative position of the inner rod and the outer rod; when unlocking, the second unlocking member 2200 drives the locking pin out of the locking hole of the outer rod through the driving hole 2100 to release the lock.

[0135] The inner rod 1100 directly or indirectly provides a second guide hole 1111. For example, a fixing seat 1110 is provided in the inner rod 1100, and the second guide hole 1111 is opened in the fixing seat 1110. The second linkage portion 2110 also extends into the second guide hole and slides under the restriction of the second guide hole to enter or exit the locking hole 1220.

[0136] The extension direction of the second guide hole 1111 is perpendicular to the length direction of the inner rod 1100. To obtain the expected movement direction of the sliding lock 2100, the second unlocking member 2200 moves along the length direction of the inner rod 1100 to control the unlocking and locking of the sliding lock 2100.

[0137] The sliding locking mechanism further includes a second elastic member 1116 for driving the second unlocking member 2200 to return to its original position after the second traction cable 2400 releases its force. The second elastic member 1116 acts between the fixing seat 1110 and the second unlocking member 2200. The sliding locking mechanism further includes a return spring 2500 that acts on the sliding locking member 2100, forcing the sliding locking member 2100 toward the locking hole.

[0138] The fixing seat 1110 is provided with a guide portion 1115 for accommodating the second elastic member 1116 and guiding the second unlocking member 2200 to reset.

[0139] Furthermore, referring to FIG. 1 to FIG. Figure 12In some implementations of the above embodiment, the control device further includes a connecting base 4400, which is slidably mounted on the inner rod 1100. The first unlocking member 4200 is slidably or rotatably mounted on the connecting base 4400, so that the first unlocking member can be switched between a relative unloaded position and an operating position. In the unloaded position, the first unlocking member avoids the control member, and in the operating position, the first unlocking member is coupled to the control member. The coupled linkage means that the first unlocking member and the control member can move synchronously, for example, when driven by the first traction cable.

[0140] The control device further includes a first operating member 4300 , which is linked to the connecting seat 4400 to drive the control member 300 to operate, for example, to unlock the controlled component 500 .

[0141] In order to reset the connection base, the control device of this embodiment further includes a third elastic member 4500 to drive the first unlocking member 4200 into the working position. The third elastic member 4500 acts between the first unlocking member 4200 and the connection base 4400 to press.

[0142] The first operating member 4300 is mounted on the inner rod, or is fixed to the inner rod as a whole. The first operating member 4300 is connected to the connecting base 4400 via a first traction cable 4100. The first traction cable 4100 can be a flexible component such as a metal wire, extending within the inner rod 1100 and facilitating rotation and extension. Because the first unlocking member 4200 slides synchronously with the inner rod relative to the outer rod, deformation of the telescopic structure 100 does not affect the operation of the first traction cable 4100, nor does it cause noticeable slack or bunching of the first traction cable 4100.

[0143] The control device further includes a first elastic member 4600, which acts between the fixed seat and the connecting seat, and is used to reset the connecting seat 4400 after the first traction cable 4100 releases its force. To facilitate the installation of the connecting seat, the fixed seat 1110 is provided with a guide structure 1112, along which the connecting seat 4400 slides and is mounted. After the first traction cable 4100 releases its force, the third elastic member 4500 drives the first unlocking member 4200 into its operating position, and the first elastic member 4600 resets the connecting seat 4400, causing the control member 300 to lock the controlled component 500.

[0144] In some embodiments, the working position of the first unlocking member 4200 is the initial position. The first unlocking member 4200 is linked to the second unlocking member 2200. During the unlocking process, the second unlocking member links the first unlocking member from the working position to the unloaded position to prevent the control member from being accidentally triggered when the telescopic structure 100 is deformed.

[0145] The connecting base 4400 defines a first guide hole 4410. The first unlocking member 4200 includes a first linkage portion 4210 that extends into the first guide hole. The first unlocking member slides within the first guide hole to switch between an idle position and an operating position. The first guide hole 4410 extends perpendicular to the length of the inner rod.

[0146] Regarding the first unlocking member 4200 being installed on the connecting seat 4400 by sliding or rotating, when the first unlocking member 4200 is installed by sliding, for example Figure 2 and Figure 6 As shown, the first linkage portion 4210 on the first unlocking member 4200 is slidably matched with the first guide hole 4410 , and the first unlocking member 4200 is slidably installed on the connecting seat 4400 .

[0147] When rotating the installation, e.g. Figure 11 As shown, a pin 4420 is provided between the first unlocking member 4200 and the connecting seat 4400 , and one end of the first unlocking member 4200 is rotatably connected to the connecting seat 4400 through the pin 4420 .

[0148] In order to make full use of the space, the control member 300 is in the shape of a rod. It can be a straight rod that slides along a straight line, or it can be an arc-shaped rod that moves along an arc path.

[0149] The linkage structure 3100 is a coupling groove, and a plurality of coupling grooves are arranged at intervals along the length direction of the control member. When at least a portion of the first unlocking member 4200 is placed in the coupling groove, it can be linked with the control member 300.

[0150] In order to realize the linkage with the first unlocking member 4200, the linkage structure 3100 can also adopt other methods, such as latch teeth, protrusions, coupling holes, etc. Figures 13 to 16 The controlled component 500 includes two components that move relative to each other. One end of the control component 300 is a working head and is used to directly or indirectly limit the relative movement of the two components. One of the components is fixedly connected to one end of the outer rod 1200, that is, the control component can lock or release the relative movement between the other component and the outer rod.

[0151] Taking two controlled components 500 as an example, the two components can slide or rotate relative to each other, and the working head simultaneously interferes with the motion paths of each component to implement locking. For example, the controlled component 500 includes a first controlled portion 501 and a second controlled portion 502 that are arranged to rotate relative to each other, and a blocking portion 503 that restricts the rotation of the first and second controlled portions 501, 502. The first and second controlled portions 501, 502 have blocking grooves that match the blocking portion 503. The blocking portion 503 is connected to the working head of the control member 300, and actuation of the controlled component 300 unlocks the first and second controlled portions 501, 502.

[0152] Among them, reference Figure 1b The fixing seat 1110 is provided with an alignment hole 1114, and the control member 300 is rod-shaped, passes through the alignment hole 1114 and further extends against the inner wall of the inner rod 1100. In other embodiments, it can also be attached to the outer wall of the inner rod or arranged at intervals.

[0153] There may also be multiple alignment holes 1114, one of which is located at the end of the connecting section of the inner rod 1100. In order to accommodate the movement of each other, the outer periphery of the inner rod 1100 or the fixing seat 1110 is provided with a guide groove 1120 for accommodating the control member 300.

[0154] Further, refer to Figures 5 to 8 In some solutions of the above embodiments, the second unlocking member 2200 defines a second linkage hole 2220, and the first unlocking member includes a first linkage portion 4210 that extends into the second linkage hole 2220. When the second unlocking member 2200 moves to unlock the telescopic structure 100, the first unlocking member 4200 is driven to the unloaded position via the second linkage hole 2220 and the first linkage portion 4210. This is a direct linkage mechanism.

[0155] Reference Figure 6 、 Figure 7 The fixing seat 1110 is provided with a guide structure 1112. The guide structure 1112 can be a cavity within the fixing seat or a slot. When the guide structure 1112 is a slot, it includes a guide section and a widening section arranged along the length of the inner rod. The widening section is adapted to the movement of the first linkage portion 4210. The inner edge of the guide section cooperates with the pin 4420 to guide the movement of the connecting seat 4400. A beveled transition is provided between the widening section and the guide section to provide guidance.

[0156] A portion of the inner edge of the second linkage hole 2220 interacts with the first linkage portion 4210, and the inner edge of this portion extends obliquely relative to the length of the first guide hole 4410. When the second unlocking member 2200 moves, the first linkage portion 4210 is pushed against by the inner edge of the second linkage hole 2220 and moves along the first guide hole 4410, thereby achieving the transition between the idle position and the working position.

[0157] Further, refer to Figure 1a 、 Figures 2 to 4 In some solutions of the above embodiments, the connecting seat 4400 is slidably mounted with a clutch seat 4700, and the second unlocking member 2200 drives the first unlocking member 4200 to enter the no-load position through the clutch seat 4700, that is, an indirect linkage is adopted.

[0158] To facilitate transmission, the second unlocking member 2200 is connected to the clutch seat 4700 via a third traction cable 4800. The third traction cable 4800 is directly or indirectly rotated 180 degrees via the fixed seat 1110, causing the second unlocking member 2200 and the clutch seat 4700 to move synchronously in opposite directions. Furthermore, the clutch seat 4700 defines a first linkage hole 4710. The first unlocking member 4200 has a first linkage portion 4210 that extends into the first linkage hole 4710. When the clutch seat 4700 moves, the first unlocking member 4200 is driven into the unloaded position via the first linkage hole 4710.

[0159] Reference Figures 9 to 12 In another embodiment of the present application, the control device of the controlled component includes: an inner rod 1100 and an outer rod 1200 that are slidably nested together; a control member 300 slidably installed in the outer rod 1000 and a first unlocking member 4200 movably installed on the inner rod 1100, the control member 300 is used to lock the controlled component 500, and the first unlocking member 4200 is used to drive the control member 300 to unlock; a sliding lock member 2100 and a second unlocking member 2200 that are movably installed in the inner rod 1100 and transmission-matched, the sliding lock member 2100 acts on the outer rod 1200 to lock the relative position of the inner rod 1100 and the outer rod 1200, the second unlocking member 2200 is used to drive the sliding lock member 2100 to unlock, and the second unlocking member 2200 and the first unlocking member 4200 move independently.

[0160] In this embodiment, the connecting base 4400 is mounted independently of the second unlocking member 2200. That is, the two do not directly contact each other, and the movement of one does not affect the other. This embodiment can, of course, be combined with the previous embodiments. For example, while the second unlocking member 2200 and the first unlocking member 4200 can move independently, multiple linkage structures can be incorporated, and the inner rod can maintain sliding contact with the control member throughout its sliding range.

[0161] Similarly, the first unlocking member 4200 has a relative no-load position and a working position, wherein the control member 300 is avoided in the no-load position and coupled with the control member 300 in the working position; in this embodiment, the no-load position of the first unlocking member 4200 is the initial position.

[0162] The first unlocking member 4200 is rotatably installed on the connecting seat 4400, and a fixed seat 1110 is provided in the inner rod 1100. The connecting seat 4400 and the second unlocking member 2200 are independently slidably connected to the fixed seat 1110. The fixed seat 1110 is provided with a guide hole 1113. The first unlocking member 4200 has a first linkage part 4210 extending into the guide hole 1113. When the connecting seat 4400 moves, the first unlocking member 4200 is driven to switch between the no-load position and the working position through the guide hole 1113 and the first linkage part 4210.

[0163] One section of the guide hole 1113 is arranged at an angle relative to the sliding direction of the connecting seat 4400, and is used to drive the first unlocking member 4200 to switch between the unloaded position and the working position. The other section of the guide hole 1113 is arranged along the sliding direction of the connecting seat 4400, and is used to facilitate the linkage between the first unlocking member 4200 and the control member. Specifically, when in the working position, the first unlocking member 4200 moves synchronously with the first traction cable 4100 pulling the connecting seat 4400 along the direction set by the other section of the guide hole 1113, driving the control member 300 to unlock the controlled component 500.

[0164] refer to Figures 13 to 16 An embodiment of the present application further provides a carrier, which may be a foldable baby carriage, etc., comprising a foldable frame, the frame comprising a load-bearing portion and a handle portion, wherein the load-bearing portion comprises a fifth component and a sixth component that move relative to each other at least when the frame is folded, the fifth component corresponding to the first controlled portion 501, the sixth component corresponding to the second controlled portion 502, and the fifth component and the sixth component serving as the controlled component 500;

[0165] In this embodiment, the bearing portion includes a front leg rod and a rear leg rod that are rotatably matched, and one of the fifth and sixth components is the front leg rod or the rear leg rod, and the other is located at the push handle portion.

[0166] The push handle part adopts a telescopic structure and includes an inner rod and an outer rod that are slidably nested and a sliding locking mechanism acting between the inner rod and the outer rod. One end of the outer rod is connected to the fixed fifth component or is an integrated structure.

[0167] The frame of this embodiment also includes:

[0168] The control member has a working head at one end for locking the relative movement of the controlled component and a coupling section at the other end. The coupling section is slidably inserted into the outer rod and is provided with at least two linkage structures.

[0169] The first unlocking member is movably mounted on the inner rod and has an unloaded position and a working position. In the unloaded position, it avoids the extension path of the coupling section. In the working position, it can couple with the corresponding linkage structure as the inner rod moves to drive the control member to unlock the controlled component and allow the fifth component and the sixth component to move relative to each other.

[0170] The first operating member 4300 and the second operating member 2300 are respectively arranged on the push handle part of the frame, and the first operating member 4300 drives the first unlocking member linkage control member 300 to unlock through the first traction rope 4100, and the second operating member 2300 drives the sliding locking mechanism to unlock through the second traction lock 2400.

[0171] An embodiment of the present application further provides a chair, comprising a seat cushion and a backrest, wherein the backrest and the seat cushion are rotationally engaged with each other, and the rotationally engaged portion comprises at least a third component 502 connected to the seat cushion and a fourth component 501 connected to the backrest, wherein the third component corresponds to the second controlled portion 502, and the fourth component corresponds to the first controlled portion 501, and the third component and the fourth component serve as controlled components;

[0172] The backrest adopts a telescopic structure and includes an inner rod 1100 and an outer rod 1200 that are slidably nested and a sliding locking mechanism acting between the inner rod and the outer rod. One end of the outer rod is fixedly connected to the fourth component or is the same component;

[0174] The control member 300 has a working head at one end for locking the relative movement of the controlled component and a coupling section at the other end. The coupling section is slidably inserted into the outer rod and is provided with at least two linkage structures.

[0175] The first unlocking member is movably mounted on the inner rod and has an unloaded position and a working position. In the unloaded position, it avoids the extension path of the coupling section. In the working position, it can couple with the corresponding linkage structure as the inner rod moves to drive the control member to unlock the controlled component and allow relative rotation between the backrest and the seat cushion.

[0176] In the vehicle and seat of the present application, the structural details and movement processes of the control parts and related components can be combined with the previous embodiments and will not be repeated here.

[0177] The technical features of the above-described embodiments may be combined in any manner.
