[0051] Figures 1 to 4 schematically illustrates a child carrier 100 provided according to a first embodiment of the present application, which includes a seat 1, a swing lock 2 and a support frame 3.

[0052] Figure 1 The seat 1 in the above-mentioned embodiments is, for example, a seat portion of a high chair for children to sit on, and the seat 1 is detachably connected to the support frame 3 via the swing lock 2 on opposite sides (left and right sides) of the seat 1. The support frame 3 can be, for example, a fixed support frame without wheels installed on the bottom, or a non-fixed support frame with wheels installed on the bottom. In some embodiments, the support frame 3 can include a first support 31 and a second support 32, wherein the bottom of the first support 31 and the bottom of the second support 32 are separated from each other, and the top of the first support 31 and the top of the second support 32 are combined to form a stable support structure. Of course, the structure of the support frame 3 is not limited to the above-mentioned examples.

[0053] The swing lock 2 can have a swing locking state and a swing unlocking state. When the swing lock 2 is in the swing unlocking state, the seat 1 is allowed to swing relative to the support frame 3, and preferably, the swing is a translation, which can have a calming effect on smaller children and increase the fun of riding for larger children. When the swing lock 2 is in the swing locking state, the swing of the seat 1 relative to the support frame 3 can be locked.

[0054] In some embodiments, the swing lock 2 can be detachably connected with the ride cabin 1, and / or the swing lock 2 can be detachably connected with the support frame 3, so that the ride cabin 1 can be separated from the support frame 3 by means of the swing lock 2, and then the same type of support frame 3 can be matched with different types of ride cabin 1, or the same type of ride cabin 1 can be matched with different types of support frame 3. In this way, the ride cabin 1 and the support frame 3 can be assembled as modules respectively, and different types of child carriers can be assembled by combining different ride cabin 1 and support frame 3, so as to meet the needs of consumers for different types of child carriers in different situations. It can be understood that through the modular design of the ride cabin 1 and the support frame 3, the use of the ride cabin 1 and the support frame 3 is improved, and accordingly the space and cost required by consumers to own multiple types of child carriers at the same time are reduced.

[0055] Referring to FIG. 1 again, Figures 1 to 3 The connection between the ride cabin 1 and the swing lock 2 of the child carrier 100 shown is detachable. The support frame 3 can be provided with a third connecting body 33, and the swing lock 2 is fixed to the third connecting body 33, for example, so as to be fixed to the support frame 3. Referring to FIG. 2, Figure 3 The third connecting body 33 is provided at the top joint position of the first support frame 31 and the second support frame 32, of course, according to the type of the support frame 3, the third connecting body 33 can be provided at any suitable position of the support frame 3. When the ride cabin 1 is installed on the support frame 3 by the swing lock 2, a high chair or a dining chair for children to ride can be formed. Figure 1 When the ride cabin 1 in Figure 1 is taken off the support frame 3, the support frame 3 can be detachably connected with other types of ride cabin, for example, referring to FIG. 3, Figure 5 The box body of the baby sleeping box can be used as the ride cabin 1 and detachably connected with the support frame 3 by the swing lock 2, and at this time the child carrier 100 can be used as a sleeping bed. Or referring to FIG. 4, Figure 6 In some embodiments, for example, a baby basket can be used as the ride cabin 1. In addition, when the ride cabin 1 is taken off the support frame 3, the ride cabin 1 can also be detachably connected with other types of support frame 3 by the swing lock 2, for example, the ride cabin 1 can be detachably connected with a movable support frame provided with wheels at the bottom, and at this time the child carrier 100 can be used as a stroller.

[0056] The child carrier provided by the embodiment of the present application can be designed as an assembly module with the ride cabin 1, the swing locking device 2 and the support frame 3, so that different ride cabins 1 and different support frames 3 can be connected by the swing locking device 2 to form various types of child carriers, thereby meeting the needs of consumers for various types of child carriers with as few assembly modules as possible, and without occupying a large storage space. In addition, the assembled child carrier 100 can be used in a swing mode or a fixed mode, and the functions of various child carriers 100 formed by assembly are also expanded.

[0057] Referring to Figures 2 to 4 , Figure 11 and Figure 12 , an exemplary detachable connection between the ride cabin 1 and the swing locking device 2 is shown. The swing locking device 2 can include a mounting housing 21, a swing rod 22 and a swing locking mechanism 23. Figure 11 and Figure 16 The mounting housing 21 is fixedly connected with the third connecting body 33 of the support frame 1. The upper end of the swing rod 22 is pivotally connected with the mounting housing 21, and the lower end of the swing rod 22 is used to detachably connect with the ride cabin 1, and the swing rod 22 drives the ride cabin 1 to swing when swinging. The swing rod 22 can be provided with two, and the two swing rods 22 constitute two opposite sides of a parallelogram to ensure that the ride cabin 1 remains horizontal during swinging, that is, to ensure that the ride cabin 1 remains translational movement during swinging. The swing locking mechanism 23 is installed on the mounting housing 21 and is used to limit (lock) the rotation of at least one swing rod 22 or release the limitation on the rotation of the at least one swing rod 22. Examples of the swing locking mechanism 23 will be described in detail below.

[0058] Referring to Figures 2 to 4To facilitate detachable connection of the swing lock 2 and the passenger cabin 1, the swing lock 2 can further comprise a first connecting body 24, which is pivotally connected with the lower ends of the two swing rods 22, for example. The passenger cabin 1 can have a second connecting body 11, which is detachably connected with the first connecting body 24. For example, the first connecting body 24 can be provided with a first protrusion 241 extending upward, the wall of the first protrusion 241 can be provided with a first clamping hole 242, the second connecting body 11 can be provided with a first recess 110 with an open bottom, and the second connecting body 11 can further be provided with a first clamping block 111, the first protrusion 241 can be inserted into the first recess 110 from the open bottom of the first recess 110 to allow the first clamping block 111 to be clamped into the first clamping hole 242. In this way, the second connecting body 11 is supported by the first connecting body 24 and the relative movement between the two is limited, so that the passenger cabin 1 and the swing lock 2 are stably connected together and are supported by the support frame 3. When it is needed to detach the passenger cabin 1 from the swing lock 2, the first clamping block 111 is controlled to be withdrawn from the first clamping hole 242, and then the passenger cabin 1 is lifted upward to disengage the first recess 110 from the first protrusion 241.

[0059] It can be understood that in other embodiments, the positions of the first protrusion 241 and the first recess 110 on the first connecting body 24 and the second connecting body 11 can be interchanged, and the positions of the first clamping block 111 and the first clamping hole 242 on the first connecting body 24 and the second connecting body 11 can also be interchanged. It can be understood that when the first protrusion 241 is provided on the second connecting body 11 and the first recess is provided on the first connecting body 24, the first protrusion 241 can extend downward and the first recess 110 can have an open top to facilitate accommodation of the first protrusion 241. The first clamping block 111 and the first clamping hole 242 can only be clamped and unclamped when the first protrusion 241 and the first recess 110 are engaged and disengaged. In addition, although in the above-mentioned embodiments, the two swing rods 22 are detachably connected with the second connecting body 11 of the passenger cabin 1 through the first connecting body 24, in some other embodiments, the lower ends of the two swing rods 22 can be directly and detachably pivotally connected with the passenger cabin 1.

[0060] Referring to Figure 2 and Figure 4 , for example, in some embodiments, the second connecting body 11 is provided with a first dismounting button 112, which is elastically supported by a spring 119, for example, the inner end of the first dismounting button 112 can be bent downward, the outer end of the first dismounting button 112 is adapted to be pressed, the first clamping block 111 is provided on the inner end of the first dismounting button 112, and preferably, the first clamping block 111 and the first dismounting button 112 can be integrally formed, and the first clamping block 111 can be hook-shaped.

[0061] It should be noted that although in the above embodiments, both sides of the passenger cabin 1 are detachably connected to the support frame 3 via the swing lock 2, in some other embodiments, only one side of the passenger cabin 1 may be detachably connected to the support frame 3 via the swing lock 2, and the other side may not have a swing lock 2 (for example, the other side may be detachably connected to the support frame 3 directly via a swing rod). It can be understood that when the swing lock 2 on one side of the passenger cabin 1 is in the swing locked state, the swing of the passenger cabin 1 relative to the support frame 3 can be locked.

[0062] It should also be noted that although the connection between the passenger cabin 1 and the mounting housing 21 of the swing lock 2 in the above embodiments is a detachable connection, in some other embodiments, the connection between the mounting housing 21 of the swing lock 2 and the support frame 3 can also be a detachable connection. Furthermore, in some embodiments, the connection between the mounting housing 21 of the swing lock 2 and the support frame 3 can be a detachable connection; in this case, the connection between the swing rod 22 of the swing lock 2 and the passenger cabin 1 may not be a detachable connection.

[0063] Figures 7 to 9 A child vehicle 100 according to a second embodiment of the present invention is shown, which also includes a passenger compartment 1, a rocking lock 2 and a support frame 3. The differences between the child vehicle 100 of this embodiment and the child vehicle 100 of the first embodiment described above will be described in detail below. The similarities or similarities between the child vehicle 100 of this embodiment and the child vehicle 100 of the first embodiment described above will not be described in detail.

[0064] Depend on Figure 8 As can be seen, the swing lock 2 may not have the first connecting body 24 in the above embodiment. The upper ends of the two swing rods 22 are pivotally connected to the mounting housing 21, and the lower ends of the two swing rods 22 are pivotally connected to the bottom of the sleeping box body, which serves as the seating cabin 1. The two swing rods 22 are parallel to each other to form two opposite sides of a parallelogram. The swing of at least one swing rod 22 can be controlled by the swing locking mechanism 23.

[0068] Referring to Figure 11 and Figure 12 , the embodiment also shows an exemplary embodiment of the swing locking mechanism 23 which can be applied to the swing lock 2 described above. The swing locking mechanism 23 can include a clamping piece 231, a lock pin 232 and a locking button 233.

[0069] Figure 11 In the embodiment, the clamping piece 231 is arranged in the mounting shell 21, the clamping piece 231 is connected with the swing rod 22 to be coaxial linkage with the swing rod 22, for example, the upper end of the swing rod 22 is bent to form a pivot shaft which is pivotally connected with the mounting shell 21, one end of the clamping piece 231 is connected with the pivot shaft and the relative rotation between them is limited, the other end of the clamping piece 231 can be provided with a clamping groove 2310. The lock pin 232 is movably installed in the mounting shell 21, and the lock pin 232 has a locking position ( Figure 12 ) which clamps into the clamping groove 2310 to limit the swing of the clamping piece 231, and a release position ( Figure 11 ) which exits from the clamping groove 2310 to allow the clamping piece 231 to swing. The locking button 233 can be kept in a first position ( Figure 11 , for example, corresponding to the release position of the lock pin 232) or a second position ( Figure 12 , for example, corresponding to the locking position of the lock pin 232), the locking button 233 has an inner end 2331 which extends into the mounting shell 23 and is operatively connected with the lock pin 232. When the locking button 233 switches between the first position and the second position, the lock pin 232 is allowed to switch between the release position and the locking position.

[0070] More specifically, referring to Figure 11A first groove 2332 can be provided at the inner end of the locking button 233, and a second groove 2132 can be provided in the mounting housing 21. The locking pin 232 passes through the first groove 2332 and the second groove 2132, and the axis of the locking pin 232 is, for example, generally perpendicular to the extending direction of the second groove 2132. The slot 2310 of the engaging member 231 can, for example, be generally parallel to the second groove 2132, and the first groove 2332 is inclined relative to the second groove 2132. Thus, when the locking button 233 switches between the first position and the second position, the first groove 2332 can push the locking pin 232 to move along the second groove 2132 (the direction of movement of the locking pin 232 is perpendicular to its axis), so that the locking pin 232 can engage with the slot 2310 or disengage from the slot 2310.

[0071] See you again Figure 11 and Figure 12 The switching between the first and second positions of the locking button 233 is achieved, for example, by pressing the locking button 233 downwards or by causing the locking button 233 to pop upwards. In some embodiments, the rocking locking mechanism 23 may further include an elastic element 234, a retainer 235, and a path guide mechanism 236. The elastic element 234 may be a spring, which is located in the mounting housing 21 and serves to support the locking button 233. The retainer 235 is disposed in one of the mounting housing 21 and the locking button 233, and the path guide mechanism 236 is disposed in the other of the mounting housing 21 and the locking button 233. The retainer 235 cooperates with the path guide mechanism 236 to lock the locking button 233 in the second position and to return the locking button 233 to the first position.

[0072] Figure 11 and Figure 12 In the swing locking mechanism 23 shown, the elastic element 234 is a spring, the lower end of the retainer 235 is pivotally connected to the mounting housing 21, the path guide structure 236 is disposed inside the locking button 233, and the upper end of the retainer 235 is slidably engaged with the path guide structure 236. The path guide structure can be a groove-shaped structure, with the upper end of the retainer 235 extending into the groove of the path guide structure 236. The working principle of the swing locking mechanism 23 is as follows: when the upper end of the retainer 235 is located in the bottom groove 2361 of the path guide structure 236 ( Figure 11 With the locking button 233 in the first position and the locking pin 232 in the unlocked position, pressing the locking button 233 downwards will cause the upper end of the retaining member 235 to move along... Figure 11 The top slot 2362 of the slide path guide structure 236 indicated by P1 ( Figure 12 At this time, the locking button 233 is in the second position, and the locking pin 232 is in the locked position. Press the locking button 233 down and then release it; the upper end of the retaining member 235 moves along...Figure 11 The chute indicated by P2 returns to the bottom slot 2361 of the path guiding structure 236, the lock button 233 returns to the first position, and the lock pin 232 returns to the released position.

[0073] Referring to Figures 13 to 20 , another exemplary structure of the swing locker 2 is shown, which also includes a mounting housing 21, a swing lever 22, and a swing locking mechanism 23. The mounting housing 21 can be detachably mounted with the support frame 3, for example, through the second recess 331 and the second clamping block 213 and the second protrusion 211 and the second clamping hole 332 of the third connecting body 33 of the support frame 3, or the mounting housing 21 can be fixed to the third connecting body 33 of the support frame 3. Referring to Figure 15 In some embodiments, the mounting housing 21 can be provided with a second detachment button 215, one end of the second detachment button 215 is provided with a second clamping block 213 suitable for extending into the second recess 331 to be clamped with the second clamping hole 332, the other end of the second detachment button 215 is elastically supported by a spring 216, for example, and the second detachment button 215 is hinged to the mounting housing 21 at a position close to the other end thereof. The spring 216 is used to keep the second clamping block 213 in the position inserted into the second clamping hole 332. By pressing the other end of the second detachment button 215, the second clamping block 213 can be rotated to disengage from the second clamping hole 332, at which time the swing locker 2 is facilitated to be separated from the support frame 3.

[0074] The upper ends of the two parallel swing levers 22 are respectively pivotally connected with the mounting housing, and the lower ends of the swing levers 22 are used to be directly or indirectly connected with the ride cabin (also referred to as a swing body) 1, for example, detachably or non-detachably, and the two swing levers 22 form two opposite sides of a parallelogram to allow the ride cabin 1 to swing while keeping horizontal (i.e., to make a translational movement). In some embodiments, the lower ends of the swing levers 22 are pivotally connected with the ride cabin 1, for example, directly. Alternatively, referring to the description of the above embodiments, the lower ends of the swing levers 22 can be provided with the aforementioned first connecting body 24, which is detachably connected with the second connecting body 11 of the ride cabin 1, for example.

[0075] Referring to Figure 16 and Figure 17, an exemplary embodiment of the swing locking mechanism 23 is shown. The swing locking mechanism 23 can include an engaging member 231, a locking pin 232, and a locking button 233. The engaging member 231 is disposed in the mounting housing 21, and the engaging member 231 is connected with the swing lever 22 to be coaxial and linked. For example, the upper end of the swing lever 22 is bent to form a pivot shaft pivotally connected with the mounting housing 21, the engaging member 231 can be sleeved with the pivot shaft and the relative rotation between the two is limited, and the engaging member 231 is provided with a clamping groove 2310. The locking pin 232 is movably disposed in the slide rail 2132 of the mounting housing 23, the first end of the locking pin 232 is in contact with the inner end of the locking button 233, when the locking button 233 is moved from the first position to the second position, the second end of the locking pin 232 is pushed by the inner end of the locking button 233 to be able to be clamped into the clamping groove 2310, and the locking pin 232 is in the locked position at this time. The reset spring 271 is disposed in the slide rail 2132, when the locking button 233 is moved from the second position to the first position, the second end of the locking pin 232 is driven by the reset spring 271 to be able to exit from the clamping groove 2310, and the locking pin 232 is in the unlocking position at this time.

[0076] There are many ways to allow the locking pin 232 to switch to the locked position clamped into the clamping groove 2310 or switch to the unlocking position exited from the clamping groove 2310 through the position movement of the locking button 233. For example, see Figure 16 and Figure 17 The extension direction of the slide rail 2132 can be substantially perpendicular to the pressing direction of the locking button 233, the inner end of the locking button 233 is provided with a slope 2331, the first end of the locking pin 232 is in contact with the slope 2331, and during the movement of the locking button 233, the locking pin 232 can move in the axial direction under the action of the slope 2331 and the reset spring 271 to switch between the locked position and the unlocking position. In other embodiments not shown, the slope 2331 can be provided on the first end of the locking pin 232, for example, the slope of the first end of the locking pin 232 is in contact with the inner end of the locking button 233, and the inner end of the locking button 233 can not be provided with a slope.

[0077] See Figure 18In some embodiments, the locking pin 232 can include a first pin 2321 and a second pin 2322 sleeved together and slidable relative to each other, the first end of the locking pin 232 being formed on the first pin 2321, and the second end of the locking pin 232 being formed on the second pin 2322. A reset spring 271 can be located between the first pin 2321 and the slide rail 2132, for pushing the first pin 2321 towards the inclined surface 2331 of the locking button 233. An adjustment spring 272 can be provided between the first pin 2321 and the second pin 2322. A clamping groove 2310 is formed in the arc-shaped peripheral wall 2313 of the clamping member 231, the central angle of the arc-shaped peripheral wall 2313 being not less than the swing angle of the swing lever 22, and the clamping groove 2310 being located, for example, in the middle of the arc-shaped peripheral wall 2313 in the circumferential direction. For better understanding, reference is made to Figure 17 and Figure 18 Even if the swing lever 22 is in an inclined state, the locking button 233 can be pressed to make the second pin 2322 extend outward and abut against the arc-shaped peripheral wall 2313, at which time the adjustment spring 2321 is compressed, and then the swing lever 22 is appropriately rotated, and when the clamping groove 2310 is aligned with the second pin 2322, the second pin 2322 is directly clamped into the clamping groove 2310 under the action of the adjustment spring 2321, thereby locking the swing of the swing lever 22.

[0078] In some embodiments, in order to prevent the first pin 2321 and the second pin 2322 from slipping, an axial limiting structure can be provided therebetween. For example, one of the first pin 2321 and the second pin 2322 can be provided with an elongated hole 23211, and the other can be provided with a protruding column 23221 passing through the elongated hole 23211, which can be formed by a screw, for example, and the protruding column 23221 cooperates with the elongated hole 23211 to prevent the first pin 2321 and the second pin 2322 from slipping. Figure 16 In some embodiments, in order to prevent the first pin 2321 and the second pin 2322 from slipping, an axial limiting structure can be provided therebetween. For example, one of the first pin 2321 and the second pin 2322 can be provided with an elongated hole 23211, and the other can be provided with a protruding column 23221 passing through the elongated hole 23211, which can be formed by a screw, for example, and the protruding column 23221 cooperates with the elongated hole 23211 to prevent the first pin 2321 and the second pin 2322 from slipping.

[0079] The switching of the locking button 233 between the first position and the second position is achieved by, for example, pressing the locking button 233 downward or making the locking button 233 pop up upward. Referring to the description in the above embodiments, the swing locking mechanism 23 can further include an elastic element 234, a retaining member 235 and a path guiding mechanism 236. The elastic element 234 can be a spring which is located in the mounting housing 21 and used to support the locking button 233. The retaining member 235 is provided in one of the mounting housing 21 and the locking button 233, and the path guiding mechanism 236 is provided in the other one of the mounting housing 21 and the locking button 233. The retaining member 235 cooperates with the path guiding mechanism 236 to enable the locking button 233 to be locked in the first position or the second position, and to be moved from the first position to the second position and from the second position back to the first position.

[0080] In addition, referring to Figure 19 and Figure 20 , another exemplary way of the retaining member 235 and the path guiding mechanism 236 is shown, and it can be understood that this kind of implementation can also be used in the swing lockers described in the above embodiments. Specifically, the retaining member 235 can include two second elastic arms 2352 provided on the locking button 233, and the free ends of the second elastic arms 2352 are provided with locking blocks 2351, for example. The path guiding mechanism 236 is provided in the mounting housing 21 and can include a first guiding surface 2365, a recess 2366 and a second guiding surface 2367 which are sequentially provided along the pressing direction P of the button. The first guiding surface 2365 is an arc surface with a middle high and two ends low, for example, the recess 2366 is located below the two ends of the first guiding surface 2365, and the second guiding surface 2367 is located below the recess 2366. When the locking button 233 is pressed downward in the first position, the locking blocks 2351 can slide along the first guiding surface 2365 into the recess 2366, and the locking blocks 2351 are clamped with the recess 2366 to retain the locking button 233 in the second position. When the locking button 233 is pressed in the second position, the locking blocks 2351 can exit from the recess 2366 along the second guiding surface 2367 and return to the first position under the action of the elastic element 234.
