[0082] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0083] 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 a central 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 a central component at the same time.

[0084] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0085] In this application, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0086] See also Figures 1 to 10The present application provides a seat of a baby carriage, which is matched with the frame of the baby carriage in a detachable manner. For the convenience of description, the seat 300 and the frame 1000 are referred to as the seat 300 and the frame 1000 below. The frame 1000 may be equipped with wheels for movement at the bottom and a handle for the user to push. In addition, the frame 1000 can be relatively unfolded and folded, and has an unfolded state and a folded state respectively. The frame 1000 has a first locking mechanism for keeping itself in the unfolded state. The first locking mechanism has a locked state and an unlocked state. When the first locking mechanism is in the unlocked state, the frame is allowed to fold. The seat 300 includes a seat plate 310 and a backrest 320 that are rotatably matched around a first axis 301. When a child sits on the seat 300, the seat plate 310 and the backrest 320 are supported respectively. The seat 300 has two sides in the width direction, and a front side and an opposite rear side to which the child faces after sitting. The first axis 301 extends along the width direction of the seat 300.

[0087] For ease of understanding, the present application describes two main components of the seat, namely the seat plate 310 and the backrest 320, but does not strictly limit the specific shapes of the two, as well as the contact points with the human body and the method of use when in use. The backrest 320 is movably mounted with a first unlocking member 330 associated with the unlocking of the first locking mechanism, and "unlocking association" is understood as a transmission association or a logical association. The transmission association can be that the first unlocking member 330 can directly unlock the first locking mechanism, that is, when the first unlocking member 330 is operated, the first locking mechanism switches to the unlocked state, or the first unlocking member 330 indirectly unlocks the first locking mechanism, that is, when the first unlocking member 330 is operated, the transmission of other intermediate components is used until the first locking mechanism switches to the unlocked state.

[0088] The logical association is understood as one or more operation steps are required for the first locking mechanism to switch to the unlocked state, and the movement of the first unlocking member 330 is one of the necessary steps, otherwise unlocking cannot be achieved.

[0089] When the movement of the first unlocking member 330 is used as an intermediate step, the first locking mechanism has not yet switched to the unlocked state and needs to cooperate with subsequent operations. For example, the first unlocking member 330 is operated to first allow the seat 300 as a whole to rotate relative to the frame 1000, and then the first locking mechanism is unlocked during the next operation, i.e., the rotation of the seat 300; for another example, the first unlocking member 330 is operated to first allow the backrest 320 to rotate relative to the seat plate 310, and then the first locking mechanism is unlocked when the backrest 320 rotates relative to the seat plate 310 in the next operation.

[0090] The seat 300 further includes a linkage 350, and the first unlocking member 330 is in transmission cooperation with the linkage 350, and the transmission cooperation includes the transmission of force and / or the change of the direction of movement. The first unlocking member 330 can drive the linkage 350 to act on the frame 1000 to implement the unlocking association. The linkage 350 is movably mounted on the seat plate 310 and / or the backrest 320 along the first axis 301. In order to avoid the overall rotation of the seat, or the movement interference when the backrest rotates relative to the seat plate, the linkage 350 can be installed on the seat plate 310, or the backrest 320, or the space jointly constructed by the seat plate 310 and the backrest 320.

[0091] The seat of the baby carriage of the present application has a first unlocking member movably arranged on the backrest and is unlocked with the first locking mechanism on the frame, that is, when the frame is folded, the first unlocking member on the backrest needs to be operated, which is different from the existing structure.

[0092] For example, in the first embodiment, the present application further provides a baby carriage 2000, comprising a foldable frame and a seat 300, wherein the seat 300 is provided with an adapter 400 and is detachably connected to the frame 1000 through the adapter 400. The frame 1000 comprises a front foot, a rear foot and a handlebar, wherein the articulation of the three includes but is not limited to rotational cooperation through a joint, and the first locking mechanism comprises at least one locking member that is transmission-coordinated with the linkage 350, wherein the locking member has a locking position that directly or indirectly acts on the three and keeps the frame in an unfolded state, and a release position that releases the action on two of the three.

[0093] The seat 300 is mounted on the frame 1000 and an unlocking operation is performed: the first unlocking member 330 is operated to drive the linking member 350 to move, directly or indirectly driving the locking member to switch from the locking position to the unlocking position, thereby achieving direct unlocking.

[0094] Further, when the seat 300 is installed on the vehicle frame, the linkage 350 corresponds to the joint.

[0095] In the second embodiment, another baby carriage 2000 is provided, comprising a foldable frame 1000 and a seat 300, wherein the seat 300 is provided with an adapter 400 and is detachably connected to the frame 1000 through the adapter 400. The frame 1000 is provided with an adapter seat 200, an adapter seat locking member 210, and a trigger member 220.

[0096] The adapter seat 200 is used for detachable connection with the seat 300. The adapter seat 200 is rotatably connected to the frame 1000, and the first locking mechanism is unlocked when the adapter seat 200 rotates relative to the frame 1000. The external force driving the adapter seat 200 to rotate can be manually applied, or provided by the gravity of the seat 300, or provided by the gravity of the adapter seat itself. In this embodiment, the driving force is provided by the gravity of the seat 300.

[0097] To ensure that the adapter seat 200 can be controlled to rotate, the adapter seat locking member 210 has a locking state that acts on the adapter seat 200 to limit its rotation relative to the frame 1000, and correspondingly has a release state that releases the action on the adapter seat 200. The trigger member 220 is movably disposed on the adapter seat 200 and is in transmission cooperation with the linkage member 350. The trigger member 220 acts on the adapter seat locking member 210 to release the adapter seat locking member 210.

[0098] The seat 300 is installed on the frame 1000 and an unlocking operation is performed: the first unlocking member 330 is operated to drive the linkage member 350 to move and directly or indirectly act on the trigger member 220, so that the trigger member 220 moves and acts on the adapter seat locking member 210 to release the lock, and the seat 300 is affected by gravity and rotates relative to the frame 1000 to drive the adapter seat 200 to rotate relative to the frame 1000, thereby unlocking the first locking mechanism.

[0099] In one embodiment, the trigger member 220 slides along the rotation axis 201 of the adapter seat 200, and the adapter seat 200 has a first surface 202 that matches the seat 300. The adapter seat 200 is provided with a groove 203 on the first surface 202, and the trigger member 220 is embedded in the groove 203. When the seat 300 and the adapter seat 200 are combined, the trigger member 220 is covered; when the seat 300 and the adapter seat 200 are separated, the trigger member 220 is exposed. The trigger member 220 is lower than or flush with the first surface 202 in a natural state (not subject to external human force). In one embodiment, the axis of the trigger member 220 coincides with the rotation axis 201.

[0100] An unlocking method is also provided: after the seat 300 is disassembled from the frame 1000, the trigger member 220 can be manually driven to release the adapter seat locking member 210, and then the adapter seat 200 is manually driven or the adapter seat 200 is driven by its own gravity to rotate to unlock the first locking mechanism.

[0101] In one embodiment, the adapter seat 200 has a first rotation direction and a second rotation direction opposite to each other relative to the frame 1000, and the adapter seat 200 has at least one first driving part 230. When the adapter seat 200 rotates in any direction, the first driving part 230 acts on the locking member to unlock the first locking mechanism. The first driving part 230 and the adapter seat 200 are integrally formed or separately fixedly connected.

[0102] The frame 1000 includes a first element, a second element, and a third element that are hinged to each other. The hinged form of the three elements can be hinged around the same axis, or hinged in pairs. One of the three elements is a front foot 120, another is a rear foot 110, and the remaining is a handle 130. The three elements constitute a support assembly 100. The adapter seat 200 is rotatably connected to the support assembly 100. The adapter seat locking member 210 is a ratchet that is slidably installed in the support assembly 100 along the rotation axis 201. The adapter seat 200 is provided with a first locking groove 204 that matches the ratchet. The trigger member 220 abuts against one side of the ratchet along the rotation axis 201. The support assembly 100 includes a first elastic member that acts on the other side of the ratchet so that the ratchet extends into the first locking groove 204 in the locked state.

[0103] The first locking mechanism includes a first locking member 141 and a second locking member 142. The configurations of the two locking members are as follows:

[0104] Solution a: The first locking member 141 is movably disposed on the first element and has a locking state for acting on the second element and a relative unlocking state; the second locking member 142 is movably disposed on the first element and has a locking state for acting on the third element and a relative unlocking state;

[0105] Or scheme b, the first locking member 141 is movably arranged on the second element, and has a locking state acting on the first element and a relative unlocking state; the second locking member 142 is movably arranged on the third element, and has a locking state acting on the first element and a relative unlocking state.

[0106] For the above two schemes, the two locking members are unlocked independently or in conjunction with each other. "Conjunction unlocking" is understood as when unlocking the first locking mechanism, the first driving part acts on one of the locking members, and unlocks the other locking member through the locking member; conversely, "independent unlocking" is understood as when unlocking the first locking mechanism, the first driving part acts on the two locking members separately.

[0107] In a preferred embodiment, there are two first driving parts 230, each of which has a first inclined surface. For scheme b and when the two locking members are unlocked independently of each other, when the adapter seat rotates along the first rotation direction, one first driving part 230 unlocks the two locking members at the same time; when the adapter seat rotates along the second rotation direction, the other first driving part 230 unlocks the two locking members at the same time; or when the adapter seat rotates in any direction, the two first driving parts 230 respectively unlock the first locking member 141 and the second locking member 142.

[0108] Attached to this application Figure 7 to Figure 9In the display scheme a, the first element is the rear foot 110, the second element is the handle 130, and the third element is the front foot 120. The handle 130, the rear foot 110 and the adapter 200 are rotatably connected around the rotation axis 201, and the front foot 120 is hinged to the rear foot 110. The first locking member 141 and the second locking member 142 are slidably arranged on the rear foot 110, and the two locking members are linked to each other through the second inclined surface. The handle 130 is provided with a second locking groove 131 matched with the first locking member 141, and the front foot 120 is provided with a third locking groove 121 matched with the second locking member 142.

[0109] When the adapter seat 200 rotates around the first rotation direction, Figure 7 and Figure 8 As shown, a first driving part 230 acts on the first locking member 141 to slide and unlock it; when the adapter seat 200 rotates around the second rotation direction, as shown in FIG. Figure 7 and Fig. 9 As shown, another first driving part 230 acts on the first locking member 141 to slide and unlock it. The first locking member 141 drives the second locking member 142 to slide and unlock through the second inclined surface. The first locking member 141 and the second locking member 142 can be unlocked synchronously or the first locking member 141 can be unlocked one step earlier than the second locking member 142.

[0110] In one embodiment, the supporting assembly 100 includes a second elastic member 143 and a third elastic member 144 acting on the first locking member 141 and the second locking member 142 respectively.

[0111] Figure 7 and Fig.10 In the embodiment, the front foot 120 is hinged to the rear foot 110 around the second axis 122, and the second axis 122 and the rotation axis 201 do not coincide. The second axis 122 is lower in height than the rotation axis 201, and the first locking member 141 and the second locking member 142 are located below the horizontal plane where the rotation axis 201 is located. In a preferred embodiment, the inner surface of the rear foot 110 is movably provided with a fifth unlocking member 111 that is linked to one of the first locking member 141 and the second locking member 142. In the figure, the fifth unlocking member 111 and the first locking member 141 are connected by fasteners, and the fifth unlocking member 111 is slidably mounted on the rear foot 110. The fifth unlocking member 111 is located below the horizontal plane where the rotation axis 201 is located, preferably below the adapter seat 200, and further preferably below the seat 300. If the adapter seat 200 is not heavy enough to cause itself to rotate relative to the support assembly 100, the operator can also directly operate the first unlocking member to unlock the first locking mechanism.

[0112] Key References Figure 7In one embodiment, a connecting rod 150 is provided between the front leg 120 and the handle 130. When the support assembly 100 is folded or unfolded, the front leg 120 and the handle 130 are linked to each other through the connecting rod 150. When the frame 1000 is in the unfolded state, at least a portion of the connecting rod 150 is located below the front leg 120 and abuts against the front leg 120. Preferably, when the frame 1000 is in the unfolded state, the connecting rod 150 is hidden in the rear leg 110.

In one embodiment, the adapter 400 is fixedly connected to the seat plate 310.

[0114] The key references Fig.14 The seat 300 includes a first transmission member 340, which rotates around the first axis 301 and is linked to the first unlocking member 330, and the linkage method is, for example, a traction rope (such as a steel wire) connected between the two. A reversing structure that cooperates with each other is provided between the linking member 350 and the first transmission member 340. When the first transmission member 340 rotates, the reversing structure drives the linking member 350 to slide along the first axis 301.

[0115] Specifically, the commutation structure includes:

[0116] A first guiding inclined surface 341 is spirally extended around the first axis 301 and is disposed on the first transmission member 340;

[0117] The second guide slope is provided on the linkage 350 and matches with the first guide slope 341. The first transmission member 340 is a columnar structure, and a protrusion is provided along one side of the first axis 301. The first guide slope 341 is provided on the protrusion, and the corresponding linkage 350 is provided with a recessed groove matching with the protrusion, and the second guide slope is provided in the recessed groove.

[0118] The linkage 350 and the first transmission member 340 are arranged along the first axis 301 , and the linkage 350 has a second driving portion 351 on one side of the first axis 301 that acts on the frame 1000 to implement unlocking. The second embodiment described below is specifically described with examples, and the second driving portion 351 acts on the trigger member 220 .

[0119] In one embodiment, the linking member 350 slides along the first axis 301 and has a first position for unlocking the first locking mechanism and a second position relative thereto. The linking member 350 is an integral structure, and a limiting structure for limiting the rotation of the linking member 350 is provided between the linking member 350 and the seat plate 310 or the backrest 320. The linking member 350 is an integral structure, and a limiting structure for limiting the rotation of the linking member 350 is provided between the linking member 350 and the seat plate 310 or the backrest 320, or;

[0120] For example Fig.14 and Fig. 22 The linkage 350 is a split structure, including a first component 352, and a second component 353 between the first component 352 and the first transmission component 340. A second driving part 351 is provided at one end of the first component 352, and the other end is against the second component 353. The second component 353 is provided with a second guide slope, and a limiting structure for limiting the rotation of the second component 353 is provided between the second component 353 and the seat plate 310 or the backrest 320. In the figure, the second component 353 is slidably mounted on the backrest 320, and the corresponding limiting structure includes a guide block 323 provided on the backrest 320 and extending along the first axis 301, and a slide groove 354 provided on the second component 353 and matched with the guide block 323. The first component 352 and the second component 353 slide synchronously and switch between the first position and the second position.

[0121] Among them Fig.15 and Fig.16 , adapters 400 are provided on both sides of the seat 300, there are two first unlocking members 330, and the corresponding linkage members 350 and first transmission members 340 and corresponding pull lines are in two groups. The two first unlocking members 330 are arranged adjacent to each other, and each is connected to the backrest 320 by sliding and / or rotation. In the figure, the first unlocking member 330 is connected to the backrest 320 by rotation. In actual operation, it is moved or pressed by the thumb and index finger. In one embodiment, the seat 300 also includes a two-way lock structure that limits the movement of the first unlocking member 330. The two-way lock structure includes a fourth unlocking member 450 slidably arranged on the backrest 320, and the fourth unlocking member 450 has a blocking portion that abuts against the first unlocking member 330 to limit its rotation unlocking operation. When the fourth unlocking member 450 slides to release the lock, the blocking portion releases the restriction on the first unlocking member 330.

[0122] like Figures 17 to 21 In one embodiment, the seat 300 also includes a second locking mechanism, which is arranged between the seat plate 310 and the backrest 320, and is used to keep the backrest 320 at different inclination angles relative to the seat plate. The second locking mechanism is unlocked only by the first unlocking member 330, or can be unlocked by a separately configured second unlocking member, wherein the second unlocking member is movably arranged on the backrest 320.

[0123] The second locking mechanism includes a plurality of locking grooves 311 arranged around the first axis 301, and a locking member 321 movably disposed on the backrest 320 and adapted to the locking groove 311. When the backrest 320 is at different angles relative to the seat plate, the locking member 321 can extend into the corresponding locking groove 311. The second unlocking member 380 is movably disposed on the backrest 320 and linked to the locking member 321, and the linkage method is, for example, a steel wire is disposed between the two.

[0124] Alternatively, the seat 300 further includes a second transmission member 360 disposed between the first transmission member 340 and the lock member 321. When the first unlocking member 330 is operated to unlock, the first transmission member 340 rotates and drives the lock member 321 to exit the lock slot 311 through the second transmission member 360. That is, when the first locking mechanism is unlocked, the second locking mechanism is unlocked at the same time, making the whole vehicle folding more convenient.

[0125] Specific combination of Figure 18 to Figure 22 The first transmission member 340 is a generally columnar structure with a first slot 342 on its circumference. The second transmission member 360 is slidably mounted in the backrest 320 along the radial direction (relative to the first axis 301) and is partially placed in the first slot 342. The first slot 342 is V-shaped. The lock member 321 and the second transmission member 360 slide in the same direction and the two contact each other. The first unlocking member 330 is operated to drive the first transmission member 340 to rotate, and the first transmission member 340 drives the second transmission member 360 to slide and push the lock member 321 out of the lock slot 311. The seat 300 includes a fourth elastic member 328 that acts on the lock member 321 to extend into the lock slot 311 and abuts against the second transmission member 360, and an elastic member (i.e., a fifth elastic member 329) that acts on the linking member 350 to reset the linking member 350 from the first position to the second position.

[0126] See also Figure 5 , Figure 23 to Figure 30 In one embodiment, the seat plate 310 is fixedly connected with an adapter 400, and the adapter 400 is used to connect with the adapter seat 200. The seat plate 310, the backrest 320 and the adapter 400 are arranged in sequence from inside to outside along the first axis 301.

[0127] The adapter 400 and the adapter seat 200 are detachably connected, and a third locking mechanism is provided between the two to limit the separation of the two. A third unlocking member 430 is movably provided on the adapter 400 to release the third locking mechanism. The third locking mechanism includes:

[0128] The second slot 240 is disposed on the adapter seat 200, specifically, on the first surface 202 of the adapter seat 200;

[0129] The card block 410 is slidably disposed on the adapter 400 and has a locked state of extending into the second card slot 240 and a released state of exiting the second card slot 240;

[0130] The sixth elastic member 420 is disposed in the adapter 400 and acts on the clamping block 410 to make it extend into the second clamping slot 240 .

[0131] The third unlocking member 430 slides radially (relative to the first axis 301) and has an unlocking position and a relative locking position for driving the clamping block 410 to exit the second clamping slot 240, wherein the third unlocking member 430 has an operating portion 431 exposed outside the adapter 400, and the operating portion 431 faces the side of the backrest.

[0132] In one embodiment, a retaining member 440 is slidably disposed in the adapter 400 and is linked to the third unlocking member 430. The retaining member 440 has a third position and a fourth position. When the third unlocking member 430 is in the unlocking position, the retaining member 440 is in the third position and keeps the third unlocking member 430 in the unlocking position; when the retaining member 440 is in the fourth position, the third unlocking member 430 can move to the locking position. The existence of the retaining member 440 allows the third unlocking member 430 to be pressed once and then released when disassembling the seat 300, keeping the third locking mechanism in the unlocked state, which is convenient for subsequent disassembly operations.

[0133] The seats also include:

[0134] a seventh elastic member, acting on the third unlocking member 430 to reset the third unlocking member 430 from the unlocking position to the locking position;

[0135] The eighth elastic member 441 acts on the retaining member 440 to switch the retaining member 440 from the fourth position to the third position.

[0136] In the figure, the retaining member 440 is a columnar structure and slides along the first axis 301. The retaining member 440 is divided into a first section 442 and a second section 443 with different radial dimensions along the sliding direction, and the radial dimension of the second section 443 is larger than that of the first section 442. The third unlocking member 430 is provided with a slide groove 432 along its own sliding direction, and the slide groove 432 is divided into a first area 433 and a second area 434 along the sliding direction. When the third unlocking member 430 is in the locked position, the first section 442 of the retaining member 440 is placed in the first area 433; when the third unlocking member 430 is in the unlocked position, the second section 443 of the retaining member 440 is placed in the second area 434 and cannot enter the first area 433, thereby preventing the third unlocking member 430 from resetting to the locked position.

[0137] Correspondingly, the first surface 202 of the adapter seat 200 is provided with a guide groove 205, and the guide groove 205 cooperates with the retaining member 440. Specifically, when the seat 300 is separated from the frame 1000, the guide groove 205 abuts against and drives the retaining member 440 to switch from the third position to the fourth position. Subsequently, the third unlocking member 430 can be reset to the locked position, waiting for the seat 300 to be reinstalled next time.

[0138] See also Fig.31 In one embodiment, the seat 300 further includes an armrest 370, which is rotatably connected between the backrest 320 and the adapter 400 around the first axis 301. A third locking member 371 is slidably provided in the seat 300 to act on the armrest 370 to put it in a use state, and the corresponding armrest 370 is provided with a fourth locking groove 372 adapted to the third locking member 371. The backrest 320 is provided with a third driving part 324 that releases the third locking member 371 when rotating and switching to the storage state. In the figure, the third driving part 324 is an inclined surface. When the backrest 320 is folded and stored, the third driving part 324 drives the third locking member 371 to exit the fourth locking groove 372, and the armrest 370 rotates close to the armrest by relying on its own gravity; when unfolded for use, the armrest 370 is independently rotated away from the seat plate 310 until the third locking member 371 extends into the fourth locking groove 372.

[0139] The seat 300 can also be applied to the vehicle frame in the first embodiment, that is, the second driving portion 351 of the linkage member 350 can directly or indirectly act on the locking member of the first locking mechanism.

[0140] The present application also provides a baby carriage, comprising a foldable frame 1000 and a seat 300, wherein the foldable frame 1000 refers to the above-mentioned embodiment. The seat 300 includes a seat plate 310, a backrest 320, a first unlocking member and a second unlocking member, wherein the seat plate 310 is used to support the child and is combined with the adapter seat 200, and the backrest 320 is connected to the seat plate 310 by rotating around a first axis 301 through a rotating joint. A second locking mechanism is arranged between the backrest 320 and the seat plate 310, and the second locking mechanism is used to keep the backrest at different inclination angles relative to the seat plate, and the second unlocking member is used to release the second locking mechanism. The first unlocking member is used to apply a release force to the adapter seat locking member 210, and the operator can adjust the inclination angle of the backrest independently through the second unlocking member, or when the whole vehicle is folded, operate the first unlocking member to simultaneously release the support assembly, the adapter seat and the backrest. The rest of the structure refers to the above-mentioned embodiment.
