[0034] Figure 1 A child carrier 200 (see FIG. Figure 3 ) of the seat 8, the seat 8 is provided with a lock 100 provided according to an embodiment of the present invention. Figure 2 The structure of a frame 9 of a child carrier 200 provided according to an embodiment of the present invention is shown. The frame 9 is provided with a connector 7 for lockingly cooperating with a lock 100 . Figures 3 to 8 The structure of a child carrier 200 assembled from a seat 8 and a frame 9 is shown. As can be seen from the figure, the child carrier 200 in the embodiment of the present invention is described by taking a child stroller as an example. It can be understood that the type of the child carrier 200 is not limited to a child stroller. For example, in other embodiments, the child carrier 200 can be a child dining chair, a baby hammock, etc. In addition, the application scope of the lock 100 provided in the embodiment of the present invention is not limited to the child carrier 200, and the lock 100 can be applied to any suitable product.

[0035] Combined with reference Figure 1 and Figure 7 The lock 100 may include a housing 1 and a release button 2 mounted on the housing 1 , a locking member 3 , a first elastic member 4 , a retaining member 5 and a second elastic member 6 .

[0036] Combined with reference Figure 7and Figure 8 In some embodiments, the housing 1 may include a first housing portion 1a and a second housing portion 1b surrounding an inner cavity 10. The housing 1 may be provided with a first opening 101 and a second opening 102. The first opening 101 is, for example, defined by the side wall of the first housing portion 1a and the side wall of the second housing portion 1b. The second opening 102 is, for example, provided on the end wall of the second housing portion 1b facing the connector 7. Figure 1 and Figure 2 , the housing 1 may also be provided with a mounting channel 120 that cooperates with the connector 7. In some embodiments, the mounting channel 120 may include, for example, a first slide groove 11 and a second slide groove 12 that are arranged in parallel, and the second opening 102 may be arranged between the first slide groove 11 and the second slide groove 12. The connector 7 may be provided with a first slide rail 71 that slidably cooperates with the first slide groove 11 and a second slide rail 72 that slidably cooperates with the second slide groove 12. The connector 7 is also provided with a locking hole 70 that is opposite to the second opening 102, and the locking hole 70 is correspondingly located between the first slide rail 71 and the second slide rail 72.

[0037] See also Figure 3 The first end 201 of the release button 2 is a force-bearing end. When the release button 2 is in an initial position (a position without being pressed), the first end 201 of the release button 2 is, for example, located outside the housing 1. The second end 202 of the release button 2 extends into the inner cavity 10 through the first opening 101.

[0038] See also Figure 6 , the first end 31 of the locking member 3 is operably connected to the release button 2 in the inner cavity 10, and the second end 32 of the locking member 3 can extend from the second opening 102 to lock with the locking hole 70 of the connecting body 7. It can be understood that the locking member 3 has a locking state in which the second end 32 extends from the second opening 102 and a release state in which the second end 32 is retracted from the second opening 102. When the locking member 3 is in the locking state, the relative movement between the connecting body 7 and the lock 100 is locked.

[0039] In some embodiments, the relative movement between the connecting body 7 and the locking device 100 can be locked only by the cooperation between the locking member 3 and the locking hole 70. Figure 1 , Figure 6 and Figure 7The first end 111 of the first slide groove 11 can be an open end, and the second end 112 of the first slide groove 11 can be a closed end; the first end 121 of the second slide groove 12 can be an open end, and the second end 122 of the second slide groove 12 can be a closed end. The second end 32 of the locking member 3 has a locking tongue portion, and it can be understood that the locking tongue portion has a wedge-shaped surface. When it is necessary to install the lock 100 and the connector 7 together, the first slide rail 71 and the second slide rail 72 of the connector 7 are inserted from the first end 111 of the first slide groove 11 and the first end 121 of the second slide groove 12 respectively. When the first slide rail 71 and the second slide rail 72 move to respectively abut against the second end 112 of the first slide groove 11 and the second end 122 of the second slide groove 12, the lock tongue portion of the locking member 3 extends into the locking hole 70 of the connector 7. At this time, the second end 112 of the first slide groove 11 and the second end 122 of the second slide groove 12 cooperate with the lock tongue portion to lock the relative movement of the connector 7 and the lock 100, so that the movement of the first slide rail 71 and the second slide rail 72 of the connector 7 relative to the first slide groove 11 and the second slide groove 12 is restricted.

[0040] It should be noted that, although in the present embodiment, the installation channel 120 may include the first slide groove 11 and the second slide groove 12, it is understood that in some embodiments, by reasonably setting the positions of the first slide groove 11, the second opening 102, and the locking member 3, the installation channel 120 may not be provided with the second slide groove 12, and accordingly, the connector 7 may not be provided with the second slide rail 72. In addition, the second end 112 of the first slide groove 11 and the second end 122 of the second slide groove 12 may not be closed ends. For example, in some embodiments, a limiting protrusion may be provided near the second end 112 of the first slide groove 11 and the second end 122 of the second slide groove 12, respectively, and the movement of the first slide rail 71 and the second slide rail 72 is stopped by these limiting protrusions.

[0041] See also Figure 6 The first elastic member 4 is used to keep the locking member 3 in a locked state. The release button 2 applies a release force to the locking member 3 when pressed, so that the locking member 3 can overcome the force of the first elastic member 4 and retract from the second opening 102 until it moves to a release state in which the second end 32 of the locking member 3 is disengaged from the locking hole 70, thereby releasing the lock 100 from the connecting body 7.

[0042] In combination with the related technology, it can be known that the release button 2 can be operably connected to the locking member 3 by any suitable structure, as long as the release button 2 and the locking member 2 satisfy the following relationship: when the release button 2 is in the initial position where it is not pressed, the second end 32 of the locking member 3 extends out and locks with the locking hole 70 of the connecting body 7; when it is necessary to release the locking engagement between the second end 32 of the locking member 3 and the locking hole 70 of the connecting body 7, the second end 32 of the locking member 3 extends out and locks with the locking hole 70 of the connecting body 7. Figure 3The release button 2 is pressed in the direction of the arrow P shown in the figure, and the release button 2 can drive the locking member 3 to move while being moved by the force, so that the second end 32 of the locking member 3 is disengaged from the locking hole 70 of the connecting body 7. In some embodiments, the moving direction of the release button 2 is perpendicular to the moving direction of the locking member 3. For example, see Figure 3 and Figure 4 In this embodiment, the movement direction of the release button 2 is radial, and the movement direction of the locking member 3 is axial. In the prior art locker, when the user no longer applies pressure to the release button 2, under the action of the first elastic member 4, the locking member 3 directly returns to the locked state and the release button 2 directly returns to the initial position.

[0043] See also Figure 4 , Figure 7 and Figure 8 , the retaining member 5 can be accommodated in the inner cavity 10, and when the release button 2 moves from the initial position to the pressing position, the retaining member 5 can be engaged with the release button 2, so that the release button 2 is maintained at the pressing position of the release locking member 3. In some embodiments, the release button 2 can be provided with a card slot 210, and the retaining member 5 can be provided with a card protrusion 521. When the release button 2 is in the pressing position, the card slot 210 and the card protrusion 521 are engaged with each other. In other words, the card slot 210 and the card protrusion 521 are engaged with each other to maintain the release button 2 in the pressing position. It can be understood that the card connection method of the retaining member 5 and the release button 2 is not limited to the above example. For example, in some embodiments, the positions of the card slot 210 and the card protrusion 521 on the release button 2 and the retaining member 5 can be interchanged.

[0044] See also Figure 4 The second elastic member 6 is used to keep the retaining member 5 in the engaging position with the release button 2. In this way, when it is necessary to release the lock of the locker 100 on the connecting body 7 to separate the two, the user does not need to press the release button 2 all the time.

[0045] See also Figure 1 and Figure 3 The retaining member 5 has an abutting top portion 511 extending into the installation channel 120. During the process of installing or removing the connecting body 7 of the lock 100, the abutting top portion 511 can be pushed by the connecting body 7, so that the retaining member 5 can overcome the force of the second elastic member 6 and disengage from the release button 2. In this way, the user does not need to directly operate the release button 2, and the release button 2 can automatically return to the initial position under the action of the first elastic member 4.

[0046] It can be understood from the above that when the release button 2 returns to the initial position, the retaining member 5 returns to the moving path of the release button 2 under the action of the second elastic member 6 (see Figure 3). When the release button 2 is pressed again and moves downward, and before it moves to the slot 210 and engages with the engaging protrusion 521, the release button 2 can drive the retaining member 5 so that the retaining member 5 can overcome the action of the second elastic member 6 and retract. In this way, the retaining member 5 withdraws from the moving path of the release button 2 without hindering the downward movement of the release button 2. When the release button 2 reaches the pressed position, the retaining member 5 is driven by the second elastic member 6 to extend and engage with the release button 2 through the engagement of the engaging protrusion 521 and the slot 210. Figure 3 In some embodiments, an inclined push surface 212 can be set on the release button 2, and an inclined push surface 5212 can be set on the retaining member 5. When the release button 2 is pressed, the inclined push surface 212 and the inclined push surface 5212 are pressed against each other, and the release button 2 can push the retaining member 5 to exit the moving path of the release button 2.

[0047] Combined with reference Figures 1 to 3 In some embodiments, the abutting top portion 511 may extend into the first slide groove 11 of the installation channel 120. In addition, the first slide rail 71 of the connector 7 may be provided with a positioning recess 710. When the connector 7 and the lock 100 are installed together, the abutting top portion 511 and the positioning recess 710 cooperate with each other so as not to affect the engagement between the retainer 5 and the release button 2. During the process of installing or removing the connector 7 by the lock 100, the first slide rail 71 moves relative to the first slide groove 11, and the first slide rail 71 may push the abutting top portion 511 to move, so that the engagement protrusion 521 of the retainer 5 is disengaged from the engagement with the engagement groove 210 of the release button 2.

[0048] See also Figure 3 , the abutting top portion 511 may be substantially trapezoidal, including a protruding top portion 5110 extending into the first slide groove 11, a first push inclined surface 5111 facing the extraction direction of the first slide rail 71, and a second push inclined surface 5112 facing the insertion direction of the first slide rail 71. Accordingly, the positioning recess 710 of the first slide rail 71 may be in a trapezoidal shape matching the abutting top portion 5111. In some embodiments, the abutting top portion 511 may be, for example, in an arc shape, in which case the positioning recess 710 of the first slide rail 71 may also be in a corresponding arc shape.

[0049] Combined with reference Figure 7 and Figure 8In some embodiments, the moving direction M1 of the release button 2 is substantially perpendicular to the moving direction M3 of the retaining member 5. Preferably, the moving direction M1 of the release button 2, the moving direction M2 of the locking member 3, and the moving direction M3 of the retaining member 5 are substantially perpendicular to each other. Such a layout contributes to the compactness of the structure of the lock 100. For example, a first guide structure 103, a second guide structure 104, and a third guide structure 105 may be provided in the inner cavity 10 of the housing 1. The release button 2 is slidably matched with the first guide structure 103, the locking member 3 is slidably matched with the second guide structure 104, and the retaining member 5 is slidably matched with the third guide structure 105.

[0050] Combined with reference Figure 7 , Figure 8 and Fig.11 In this embodiment, a preferred implementation of the retaining member 5 is shown. The retaining member 5 may include a bottom 53, a first extension portion 51, and a second extension portion 52. The first extension portion 51 and the second extension portion 52 extend from the bottom 53 and are opposite to each other. The first slide groove 11 passes through the middle of the first extension portion 51 and the second extension portion 52. The abutting top portion 511 is located at the first extension portion 51, and the snap-on protrusion 521 is located at the second extension portion 52 and faces away from the first slide groove 11. The second elastic member 6 may be a spring, and the bottom 53 of the retaining member 5 may be provided with a mounting groove 530, the first end of the second elastic member 6 is accommodated in the mounting groove 530, the second end 62 of the second elastic member 6 extends away from the release button 2, and the second end 62 of the second elastic member 6, for example, abuts against the cavity wall of the inner cavity 10.

[0051] Combined with reference Figures 7 to 10 , this embodiment also shows a preferred embodiment of the release button 2 and the locking member 3, wherein the release button 2 may include a pressing portion 23, a first arm 21 and a second arm 22, the first arm 21 and the second arm 22 extending from the pressing portion 23 and facing each other. The pressing portion 23 is located at the first end 201 of the release button 2, and the ends of the first arm 21 and the second arm 22 form the second end 202 of the release button 2. The locking member 3 is located between the first arm 21 and the second arm 22, the first arm 21 is close to the retaining member 5 and is provided with a card slot 210, and the second arm 22 may be away from the retaining member 5. The first arm 21 and the second arm 22 may be respectively provided with a third inclined surface 25 for contacting the locking member 3, and the locking member 3 may be provided with a fourth inclined surface 36 for contacting the first arm 21 and the second arm 22 respectively. In this embodiment, the third inclined surface 25 and the fourth inclined surface 36 are slidably matched. It is understood that in other embodiments, the third inclined surface 25 and the fourth inclined surface 36 can be set at one or the other, and the operable connection between the release button 2 and the locking member 3 can also be achieved. The first elastic member 4 can be a spring, and one end of the first elastic member 4 is in contact with the locking member 3, and the other end is against the wall of the inner cavity 10.

[0052] An embodiment of the present invention also provides a locking structure, which includes the aforementioned lock 100 and the aforementioned connecting body 7. After the sliding rail of the connecting body 7 (for example, including the first sliding rail 71 and the second sliding rail 72) is inserted into the installation channel 120 (for example, including the first sliding groove 11 and the second sliding groove 12) of the lock 100, the locking member 3 of the lock 100 is inserted into the locking hole 70 of the connecting body 7, and the lock 100 is firmly connected to the connecting body 7.

[0053] The embodiment of the present invention further provides a child carrier 200, which includes a seat 8 and a frame 9, and the aforementioned locking structure. One of the seat 8 and the frame 9 is equipped with a locker 100, and the other is equipped with a connector 7.

[0054] Combine the following Figures 1 to 5 The disassembly and assembly process of the seat 8 and the frame 9 in the child carrier 200 using the locking structure provided by the embodiment of the present invention will be described in detail.

[0055] During installation, align the seat 8 and the frame 9, insert the first slide rail 71 and the second slide rail 72 into the first slide groove 11 and the second slide groove 12, until the locking member 3 is inserted into the locking hole 70. Figure 3 At this time, the release button 2 is in the initial position, the second end of the locking member 3 is inserted into the locking hole 70 , and the abutting top portion 511 extends into the positioning recess 710 .

[0056] When disassembling, refer to Figure 4 , press the release button 2 downward, the release button 2 pushes the locking member 3 to retract, so that the locking member 3 withdraws from the locking hole 70. The release button 2 pushes the retaining member 5 to retract at the same time. When the release button 2 moves to the pressing position where its card slot 210 and the card protrusion 521 of the retaining member 5 are aligned, under the action of the second elastic member 6, the card protrusion 521 of the retaining member 5 is carded into the card slot 210, so that the release button 2 remains in the pressing position, and the locking member 3 remains in the released state of being disengaged from the locking hole 70. At this time, the seat 8 can be removed from the frame 9 by lifting it. During the process of disassembling the seat 8, the first slide rail 71 pushes the first push inclined surface 5111 to move, so that the engaging protrusion 521 retracts from the engaging groove 210 and disengages from the engaging groove 210, and the release button 2 returns to its initial position under the action of the first elastic member 4 (at this time, the second end 32 of the locking member 3 has been disengaged from the locking hole 70, and even if it extends outward again after the release button 2 returns to its original position, it will not engage with the locking hole 70, so it will not affect the disassembly of the seat 8). When the seat 8 is disassembled from the frame 9, the release button 2 and the retaining member 5 return to their original position. Figure 8 Position shown.

[0057] After the seat 8 is removed from the frame 9, the release button 2 may be retained in the pressed position of the release lock member 3 by the retaining member 5 due to being pressed accidentally.
