[0002] With the rapid pace of modern life and the increasing emphasis of parents on children's safety and comfort, baby carrycots and the strollers used in combination with them have become indispensable equipment in daily life. In the prior art, baby carrycots are usually connected to strollers through fixing devices or hook mechanisms. Although these traditional connection methods ensure a certain connection stability, there are many inconveniences in actual operation. For example, when it is necessary to remove the carrycot from the stroller, parents need to operate the unlocking mechanism and support the weight of the carrycot at the same time, which is particularly difficult for parents with less strength or those who are holding a baby and operating with one hand. Therefore, it is particularly important to design a quick-release mechanism that can be operated with one hand. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a quick-release mechanism based on a carrycot stroller, which adds a release lock holding component to the lock hook of the existing connector between the carrycot and the stroller, and maintains the release lock state of the lock hook through this release lock holding component, so as to facilitate separating the carrycot from the stroller with one hand.

[0004] To solve the above technical problems, the utility model provides a quick-release mechanism based on a carrycot stroller, which realizes quick fixing or unlocking between the carrycot and the stroller connector, and includes a lock hook arranged inside the carrycot. By rotating the lock hook, two states of locking or unlocking between the carrycot and the stroller connector are switched;

[0005] The lock hook is configured with a release lock holding component, and the release lock state of the lock hook is maintained through this release lock holding component, so as to facilitate separating the carrycot from the stroller with one hand.

[0006] Preferably, a lower engaging hook is provided at the bottom of the lock hook. When the lower engaging hook engages with the lock tongue inside the stroller connector, the carrycot and the stroller connector are in a locked state. When the lower engaging hook is separated from the lock tongue inside the stroller connector, the carrycot and the stroller connector are in a released lock state.

[0007] Preferably, an upper engaging hook is provided at the top of the lock hook, and the release lock state of the lock hook is maintained by engaging the upper engaging hook with the release lock holding component.

[0008] Preferably, the release lock holding component includes a housing fixedly connected to the carrycot. A linkage shaft is slidably arranged inside the housing, and the linkage shaft engages with the upper engaging hook, thereby maintaining the release lock state of the lock hook.

[0009] Preferably, the unlocking and holding component further includes a linkage shaft return spring disposed inside the housing. Under the action of the linkage shaft return spring, the linkage shaft is pushed to engage with the upper engaging hook.

[0010] Preferably, there are two sets of the linkage shaft return springs, symmetrically distributed in the sliding grooves on both sides of the housing, so that the linkage shaft slides along the sliding grooves.

[0031] The present utility model provides a quick-release mechanism based on a carrycot stroller, which realizes the quick fixation or unlocking between the carrycot 100 and the stroller connector 200. For details, please refer to Figure 1 and Figure 2 . The quick-release mechanism includes a locking hook 1 disposed inside the carrycot 100. By rotating the locking hook 1, two states of locking or unlocking between the carrycot 100 and the stroller connector 200 are switched; the locking hook 1 is configured with an unlocking holding component 2, and the unlocking state of the locking hook 1 is maintained by the unlocking holding component 2, so as to facilitate separating the carrycot from the stroller with one hand, thereby meeting the usage requirements of parents with less strength or parents holding a baby in their arms and needing to operate with one hand.

[0032] Specifically, as shown in Figure 3 and Figure 4 , a lower engaging hook 101a is provided at the bottom of the locking hook 1. When the lower engaging hook 101a engages with the locking tongue 210 inside the stroller connector 200, the carrycot 100 and the stroller connector 200 are in a locked state. When the lower engaging hook 101a is separated from the locking tongue 210 inside the stroller connector 200, the carrycot 100 and the stroller connector 200 are in an unlocked state.

[0033] Furthermore, an upper engaging hook 101b is provided at the top of the locking hook 1, and the upper engaging hook 101b engages with the unlocking holding component 2, thereby maintaining the unlocking state of the locking hook 1.

[0034] Furthermore, as shown in Figure 5 and Figure 6 , the unlocking holding component 2 includes a housing 201a fixedly connected to the carrycot 100. A linkage shaft 201b is slidably disposed inside the housing 201a, and the linkage shaft 201b engages with the upper engaging hook 101b, thereby maintaining the unlocking state of the locking hook 1.

[0035] Moreover, the unlocking and retaining component 2 further includes a linkage shaft return spring 201c disposed within the housing 201a. Under the action of the linkage shaft return spring 201c, the linkage shaft 201b is pushed to engage with the upper engaging hook 101b. That is to say, the linkage shaft return spring 201c can provide a thrust force such that the linkage shaft 201b is always engaged with the upper engaging hook 101b, thereby maintaining the unlocked state of the locking hook 1. However, when the external force is greater than the elastic force of the linkage shaft return spring 201c, the upper engaging hook 101b will disengage from the linkage shaft 201b due to the rotation of the locking hook 1, enabling the lower engaging hook 101a at the bottom of the locking hook 1 to engage with the locking tongue 210 within the stroller connector 200, so as to achieve the locked state of the carrycot 100 and the stroller connector 200.

[0036] In some embodiments, there are two sets of the linkage shaft return springs 201c, symmetrically distributed in the sliding grooves 201d on both sides of the housing 201a, enabling the linkage shaft 201b to slide along the sliding grooves 201d. Meanwhile, the sliding grooves 201d are obliquely formed along the movement trajectory of the upper engaging hook 101b. When the locking hook 1 rotates around its middle part, the movement trajectory of the upper engaging hook 101b is arc-shaped. Therefore, the sliding grooves 201d are obliquely formed so that the linkage shaft 201b can slide obliquely to ensure effective engagement with the upper engaging hook 101b.

[0037] Specifically, please continue to refer to Figure 3 and Figure 4 , a rotating shaft 101c is provided in the middle part of the locking hook 1, and both ends of the rotating shaft 101c are rotatably connected to the carrycot 100 and the unlocking component decorative cover 300 respectively, so that the locking hook 1 rotates around the rotating shaft 101c in the carrycot 100 for switching between the two states of locking or unlocking between the carrycot 100 and the stroller connector 200; an unlocking button 101d is provided at one end of the locking hook 1 close to the upper engaging hook 101b, and by pressing the unlocking button 101d, the locking hook 1 is driven to rotate, and the upper engaging hook 101b is engaged with the linkage shaft 201b.

[0038] Furthermore, an elastic push piece 101e extends outward from the middle part of the locking hook 1. When the carrycot 100 is inserted into the stroller connector 200, the locking hook 1 extends into the stroller connector 200. At this time, the elastic push piece 101e contacts the top of the stroller connector 200, and under the mutual acting force, the locking hook 1 is driven to rotate around the rotating shaft 101c.

[0039] Furthermore, a boss 101f is also provided in the middle part of the locking hook 1, and a locking hook return spring is arranged on the boss 101f to assist the locking hook 1 in resetting.

[0040] When in use, when the unlocking button 101d is pressed, the linkage shaft 201b moves in the sliding groove 201d under the action of the locking hook 1. When the unlocking button 101d is continuously pressed, the linkage shaft 201b is snapped into the upper engaging hook 101b at the top of the locking hook 1 under the action of the linkage shaft return spring 201c. At this time, the lower engaging hook 101a at the bottom of the locking hook 1 is separated from the locking tongue 210 in the trolley connector 200. By lifting the basket upward, the unlocking function can be realized.

[0041] When it is necessary to fix the basket and the trolley, align the basket 100 downward with the trolley connector 200 and slowly move the basket downward. The upper part of the trolley connector 200 contacts the elastic push piece 101e on the upper surface of the locking hook 1 and pushes the locking hook 1 to rotate upward. When the external force is greater than the elastic force of the linkage shaft return spring 201c, the upper engaging hook 101b will disengage from the linkage shaft 201b due to the rotation of the locking hook 1, so that the lower engaging hook 101a at the bottom of the locking hook 1 can engage with the locking tongue 210 in the trolley connector 200. When a clicking sound is heard, the basket is fixed to the trolley.

[0042] The above description is only a description of the preferred embodiments of the present invention, and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the field of the present invention based on the above disclosure are within the protection scope of the claims.
