As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0055] As Figure 1 and Figure 2As shown, an embodiment of the present application provides a child carrier, which can be a child safety seat, comprising a seat 100, a body 200, an adjusting mechanism 300, an operating member 400 and a locking mechanism 500. The body 200 is detachably fixed to the seat 100, and a seating space 600 for accommodating a child is formed between the body 200 and the seat 100. The adjusting mechanism 300 is arranged between the body 200 and the seat 100, and is used to adjust the distance between the body 200 and the seat 100, i.e. to adjust the size of the seating space 600. The adjusting mechanism 300 is arranged on both sides of the body 200, and the operating member 400 is connected to the adjusting mechanism 300 on each side of the body 200. Alternatively, the adjusting mechanism 300 can be arranged on one side of the body 200, and a linkage mechanism (not shown) is arranged on the other side of the body 200, and the operating member 400 is connected to the adjusting mechanism 300 and the linkage mechanism. The locking mechanism 500 is used to realize the detachable connection between the body 200 and the seat 100. The child carrier can realize one-handed adjustment of the distance between the body 200 and the seat 100, and is convenient to use.

[0056] Specifically, as shown in Figure 1 and Figure 5 , the seat 100 comprises a seat back 110 and a seat pan 120 connected to each other. The body 200 can be a light-weight solid block structure or a shell structure made of foamed polystyrene (EPS), foamed polypropylene (EPP) or foamed polyethylene-polystyrene (EPO) and the like. In this embodiment, the body 200 has a first surface 210 facing the seat 100, and the first surface 210 is concave to enclose the seat 100 to form the seating space 600 for accommodating a child. The body 200 also has a second surface 220 facing away from the seat 100, and the second surface 220 is convex and substantially partially spherical.

[0057] As shown in Figures 5 to 10 , the adjusting mechanism 300 is used to adjust the distance between the body 200 and the seat 100, i.e. to adjust the size of the seating space 600. Specifically, the adjusting mechanism 300 comprises an adjusting assembly 310, a sliding assembly 320, a release assembly 330 and a connecting member 340. The adjusting assembly 310 is fixed to either side 230 of the body 200, the sliding assembly 320 is used to be connected to the seat 100, and the adjusting assembly 310 is slidingly connected to the sliding assembly 320. The release assembly 330 is used to release the locking between the adjusting assembly 310 and the sliding assembly 320. The connecting member 340 is fixed to the sliding assembly 320 and is used to be detachably connected to the seat 100.

[0058] Specifically, as shown in Figure 5 and Figure 6As shown, the adjusting assembly 310 comprises an adjusting body 311 and a second reset member 312. The adjusting body 311 is substantially in a long tubular structure, one side of the adjusting body 311 is fixed to either side 230 of the guard body 200, and a plurality of clamping holes 311a are arranged along the length direction of the side of the adjusting body 311 which is away from the guard body 200.

[0059] Further, as shown in Figures 5 to 7 the sliding assembly 320 is arranged on the side 230 of the adjusting assembly 310 which is away from the guard body 200 and is in sliding connection with the adjusting assembly 310. Specifically, the sliding assembly 320 comprises a sliding body 321, a clamping member 322 and a first reset member 323. The sliding body 321 is substantially in a shell structure. The clamping member 322 is movably arranged in the sliding body 321, and the clamping member 322 comprises a clamping body 322a and a clamping tooth 322b fixed to the clamping body 322a. The sliding body 321 has a through hole (not shown in the drawings) on the side which faces the adjusting body 311, and the clamping member 322 can be moved to make the clamping tooth 322b protrude out of the outer surface 314 of the sliding body 321 which faces the adjusting body 311 through the through hole, and make the clamping tooth 322b be in clamping connection with the clamping hole 311a.

[0060] In this way, the relative locking between the sliding assembly 320 and the adjusting assembly 310 can be realized, so that the guard body 200 is fixed at a certain distance from the seat 100 to form a certain size of the seating space 600. When the sliding assembly 320 and the adjusting assembly 310 are relatively slid to make the clamping tooth 322b be clamped in different clamping holes 311a, the size of the seating space 600 can be adjusted.

[0061] In the embodiment, as shown in Figure 7 the clamping tooth 322b is two, so as to improve the clamping stability between the clamping tooth 322b and the clamping hole 311a. Of course, in other embodiments, the number of the clamping tooth 322b can also be adjusted according to actual needs.

[0062] Further, as shown in Figure 6 and Figure 7 the two ends of the first reset member 323 are respectively in abutment with the clamping member 322 and the sliding body 321, and the first reset member 323 always moves the clamping member 322 towards the guard body 200, so that the clamping tooth 322b and the clamping hole 311a can be automatically re-clamped.

[0063] Of course, the matching manner between the adjusting assembly 310 and the sliding assembly 320 is not limited to this. The engaging hole 311a can be replaced by a slot, a ring or other matching parts according to actual needs, and the engaging tooth 322b can be replaced by a protrusion, a hook or other matching parts according to actual needs. In the embodiment, the adjusting assembly 310 is provided with a plurality of first matching parts (for example, the engaging hole 311a), and the sliding assembly 320 is provided with a second matching part (for example, the engaging tooth 322b) for matching with the first matching part. Of course, in other embodiments, the positions of the first matching part and the second matching part can also be interchanged, as long as the adjusting assembly 310 and the sliding assembly 320 can be relatively fixed at different positions, and the specific form is not limited.

[0064] Further, as shown in Figure 7 and Figure 10 , one side of the engaging tooth 322b also has a sliding slope 322c, which is used to abut against the hole wall 311b of the engaging hole 311a. In this way, assuming that the sliding slope 332c gradually moves away from the guard body 200 along the first direction F1, when it is needed to move the guard body 200 in the opposite direction of the first direction F1, it is only needed to push the guard body 200 in the opposite direction of the first direction F1, and the hole wall 311b of the engaging hole 311a on the adjusting body 311 will push the sliding slope 322c, so that the engaging piece 322 as a whole moves upward to make the engaging tooth 322b disengage from the engaging hole 311a, and the adjusting assembly 310 and the sliding assembly 320 are unlocked, while the guard body 200 moves in the opposite direction of the first direction F1.

[0065] In the embodiment, the sliding slope 322c is located on the side of the engaging tooth 322b facing the first direction F1 and gradually moves away from the guard body 200 along the first direction F1. When it is needed to move the guard body 200 to the direction close to the seat 100, that is, to reduce the seating space 600, it is only needed to push the guard body 200 to the direction close to the seat 100. As shown in Figure 6 、 Figure 7 、 Figure 9 and Figure 10The release assembly 330 is used to push the engaging member 322 to disengage the engaging member 322 from the engaging hole 311a. The release assembly 330 includes a linkage member 331 and a driving member 332 connected with each other. The linkage member 331 is in a rod-like structure, one end of the linkage member 331 is fixedly connected with the operating member 400 and is driven to move by the operating member 400. The linkage member 331 extends into the adjusting body 311 and is located at the side 230 of the adjusting body 311 close to the sheath 200, and the side 230 of the linkage member 331 away from the sheath 200 is provided with a first driving slope 331a. The two ends of the second reset member 312 are respectively abutted against the linkage member 331 and the adjusting body 311, and the second reset member 312 always drives the linkage member 331 to move in the opposite direction of the direction of releasing the driving member 332, for example, in the opposite direction of the first direction F1. Specifically, the rivet 313 is fixed on the adjusting body 311, and the two ends of the second reset member 312 are respectively abutted against the linkage member 331 and the rivet 313.

[0066] As shown in Figure 6 , Figure 7 , Figure 9 and Figure 10 , the driving member 332 is arranged in the adjusting body 311 and can push the engaging member 322 to disengage the engaging member 322 from the engaging hole 311a. The driving member 332 is in a rod-like structure and is arranged in the adjusting body 311 away from the side 230 of the sheath 200. The side 230 of the driving member 332 away from the sheath 200 is provided with a plurality of pushing protrusions 332a abutted against the engaging member 322, and the plurality of pushing protrusions 332a are arranged corresponding to the plurality of engaging holes 311a. The pushing protrusions 332a can pass through the engaging holes 311a to protrude out of the outer surface 314 of the adjusting assembly 310 to push the engaging teeth 322b, so that the engaging teeth 322b are disengaged from the engaging hole 311a. Thus, the locking between the adjusting assembly 310 and the sliding assembly 320 is released, and the adjusting assembly 310 and the sliding assembly 320 can slide relative to each other to adjust the size of the seating space 600 between the sheath 200 and the seat 100.

[0067] As shown in Figure 6 , Figure 7 , Figure 9 and Figure 10As shown, the driving member 332 has a second driving slope 332b on the side 230 of the guard body 200, which is matched with the first driving slope 331a. In this embodiment, the second driving slope 332b gradually moves away from the engaging hole 311a along the first direction F1. Thus, when it is needed to move the guard body 200 along the first direction F1, the connecting member 331 can be pulled to move along the first direction F1. Thus, the second driving slope 332b of the driving member 332 will move away from the guard body 200 under the pushing of the first driving slope 331a, so that the driving member 332 as a whole moves away from the guard body 200, i.e. moves towards the engaging hole 311a, and then the pushing protrusion 332a on the driving member 332 can protrude from the outer surface 314 of the adjusting assembly 310 to push the engaging tooth 322b, so that the engaging tooth 322b is disengaged from the engaging hole 311a.

[0068] Further, as shown, Figures 1 to 4 the operation member 400 is in a rod-like structure, and in this embodiment, the two ends of the operation member 400 are fixedly connected with the connecting members 340 of the adjusting assemblies 300 on the two sides of the guard body 200. Of course, in other embodiments, the middle part or other positions of the operation member 400 can be fixedly connected with the connecting members 340 of the adjusting assemblies 300 on the two sides of the guard body 200. Thus, by pulling the operation member 400, the two adjusting assemblies 300 can be simultaneously acted on to adjust the distance between the guard body 200 and the seat 100, which can be operated by one hand, without the need to simultaneously stretch both hands to the two sides of the guard body 200 to adjust the adjusting assemblies 300, and the operation is convenient. In this embodiment, the operation member 400 is located on the side of the guard body 200 away from the seating space 600, i.e. the second surface 220, which is more convenient for the user to operate. Of course, in other embodiments, the operation member 400 can be located on the top of the guard body 200 or other positions, as long as it is convenient to operate.

[0069] As shown, Figure 1 , Figure 2 and Figures 5 to 10 , the adjusting process of the guard body 200 relative to the seat 100 is as follows:

[0070] When it is needed to move the guard body 200 away from the seat 100, i.e. to increase the seating space 600, the operation member 400 is pulled away from the seat 100, and the connecting member 331 is driven by the operation member 400 to move along the first direction F1. The driving member 332 originally matched with the first driving slope 331a of the connecting member 331 by the second driving slope 332b is pushed by the first driving slope 331a to move away from the guard body 200, so that the pushing protrusion 332a on the driving member 332 pushes the engaging tooth 322b, and finally the engaging tooth 322b is disengaged from the engaging hole 311a, as shown in Figure 10The adjusting assembly 310 and the sliding assembly 320 are unlocked and can slide relative to each other. Since the adjusting assembly 310 is fixed to the body 200 and the sliding assembly 320 is connected to the seat 100, the adjusting assembly 310 slides relative to the sliding assembly 320, which is equivalent to the body 200 sliding relative to the seat 100. Thus, the adjusting assembly 310 moves relative to the sliding assembly 320 in the first direction F1, and the distance between the body 200 and the seat 100 increases, i.e., the sitting space 600 increases. After the adjusting assembly 310 moves to the desired position relative to the sliding assembly 320, the operating member 400 is released, the connecting member 331 moves in the opposite direction of the first direction F1 under the action of the second reset member 312, and the driving member 332 moves towards the body 200. At the same time, the clamping member 322 also moves towards the body 200 under the action of the first reset member 323, and finally the clamping teeth 322b are clamped with other clamping teeth 322b, as shown in the figure, so as to realize the relative fixation of the adjusting assembly 310 and the sliding assembly 320, i.e., the relocking of the body 200 and the seat 100.

[0071] When it is needed to move the body 200 towards the seat 100, i.e., to reduce the sitting space 600, the body 200 is only needed to move in the opposite direction of the first direction F1. At this time, the sliding slope 322c on the clamping member 322 moves upwards under the pushing action of the hole wall 311b of the clamping hole 311a, and the clamping teeth 322b are disengaged from the clamping hole 311a, i.e., the adjusting assembly 310 and the sliding assembly 320 are unlocked, the body 200 and the seat 100 are unlocked, the body 200 moves towards the seat 100, and the sitting space 600 is reduced. When the body 200 moves to the desired position relative to the seat 100, the pushing of the body 200 is stopped, the clamping member 322 moves towards the body 200 under the action of the first reset member 323, and the clamping teeth 322b are clamped with other clamping holes 311a, so as to realize the relative fixation of the adjusting assembly 310 and the sliding assembly 320, i.e., the relocking of the body 200 and the seat 100.

[0072] As shown in Figures 11 to 14 The locking mechanism 500 has a locked state and a released state. When the locking mechanism 500 is in the locked state, the body 200 is locked and fixed to the seat 100. When the locking mechanism 500 is in the released state, the body 200 can be detached from the seat 100. Specifically, the locking mechanism 500 includes a connecting portion 510 (as Figure 3 and Figure 4The connecting part 510 is arranged on the connecting member 340, the locking housing 520 is fixed on the seat 100, the connecting pin 530 is movably arranged in the locking housing 520, the release button 540 is connected with one end of the connecting pin 530, and the two ends of the third reset member 550 are respectively abutted against the release button 540 and the locking housing 520.

[0073] As shown in Figure 3 and Figure 4 , the connecting part 510 specifically comprises the connecting hole 511 and the connecting port 512 arranged on the connecting member 340 and connected with each other, and the hole diameter of the connecting hole 511 is greater than the port diameter of the connecting port 512. In the embodiment, the connecting part 510 is arranged on the end of the connecting member 340 away from the sliding assembly 320, but is not limited thereto.

[0074] As shown in Figure 12 and Figure 14 , the locking housing 520 is substantially a cuboid housing structure, and an accommodating cavity 521 for accommodating the connecting pin 530 is arranged in the locking housing 520. The locking housing 520 is provided with a plug port (not shown in the drawings) in communication with the accommodating cavity 521, and the plug port is used for inserting the connecting member 340.

[0075] As shown in Figure 12 , Figure 14 and Figure 15 , the connecting pin 530 is substantially a columnar structure, and comprises the fixed part 531, the release part 532 and the blocking part 533 connected in sequence. The fixed part 531 is used for connecting with the release button 540, the radial dimension R1 of the release part 532 is less than the port diameter of the connecting port 512, the radial dimension R2 of the blocking part 533 is greater than the port diameter of the connecting port 512 and less than the hole diameter of the connecting hole 511, the connecting pin 530 is inserted into the connecting hole 511 through the connecting port 512, and the connecting pin 530 is movable so that the blocking part 533 or the release part 532 is located in the connecting hole 511.

[0076] As shown in Figure 12 and Figure 14 , the release button 540 is fixed on the fixed part 531 of the connecting pin 530, and the release button 540 is partially arranged in the accommodating cavity 521 and partially protrudes from the surface of the locking housing 520 for pressing operation.

[0077] Thus, when it is needed to install and fix the guard body 200 on the seat 100, the connecting member 340 is inserted into the plug port of the locking housing 520, and the connecting pin 530 is inserted into the connecting hole 511 through the connecting port 512. Figure 12 and Figure 14The second direction F2 in the figure presses the release button 540, and the end of the connecting piece 340 with the connecting part 510 is inserted into the accommodating cavity 521 through the insertion port, and the insertion direction of the connecting piece 340 is perpendicular to the length direction of the connecting pin 530. At this time, the release part 532 of the connecting pin 530 is opposite to the connecting port 512, and since the radial dimension R1 of the release part 532 is smaller than the caliber of the connecting port 512, the connecting pin 530 is inserted into the connecting hole 511 through the connecting port 512, as shown in Figure 14 Then, the release button 540 is loosened, and the release button 540 is reset in the opposite direction of the second direction F2 under the action of the third reset member 550, and the connecting pin 530 is moved to the opposite direction of the second direction F2, so that the blocking part 533 of the connecting pin 530 is located in the connecting hole 511 and opposite to the connecting port 512, and since the radial dimension R2 of the blocking part 533 is greater than the caliber of the connecting port 512 and smaller than the caliber of the connecting hole 511, the blocking part 533 forms a blocking action on the connecting port 512, and the connecting piece 340 cannot be pulled out from the accommodating cavity 521, as shown in Figure 12 Thus, the connection and fixation between the sliding assembly 320 and the seat 100 can be realized, that is, the installation and fixation of the guard body 200 on the seat 100.

[0078] When it is needed to detach the guard body 200 from the seat 100, the release button 540 is pressed in the second direction F2, so that the connecting pin 530 is moved to the opposite direction of the second direction F2, and the release part 532 of the connecting pin 530 is located in the connecting hole 511 and opposite to the connecting port 512, as shown in Figure 14 Since the radial dimension R1 of the release part 532 is smaller than the caliber of the connecting port 512, the release part 532 can be moved out of the connecting hole 511 from the connecting port 512, that is, at this time, the end of the connecting piece 340 with the connecting part 510 can be pulled out from the accommodating cavity 521, the fixation between the sliding assembly 320 and the seat 100 is released, and the guard body 200 can be detached from the seat 100.

[0079] Of course, other ways can also be used to realize the detachable connection between the guard body 200 and the seat 100, for example, a rotatable connecting hook is arranged on the sliding assembly 320, and a connecting hole 511 matched with the connecting hook is arranged on the seat 100, and the like, which is not limited.

[0080] The child carrier of the application has at least the following technical effects:

[0081] The child carrier, one side of the body 200 is provided with adjusting mechanism 300 for adjusting the size of the seat space 600, and through the operating member 400 and the adjusting mechanism 300 on one side of the body 200 is connected, so, by operating the operating member 400 can be just for the adjusting mechanism 300 on one side of the body to adjust the distance between the body 200 and the seat 100, that is, adjust the size of the seat space 600, single-handed operation, without the need for two hands on both sides of the body 200 adjustment, easy to use.
