[0002] With the continuous improvement of living standards, there is an increasing number of children's products designed specifically for children. Among them, child safety seats are widely used because they provide safety for children while traveling in vehicles. In the event of a frontal collision, a child in the vehicle is thrown forward due to inertia. The safety devices on a child safety seat can limit this forward movement. Without the protection of a child safety seat, a child could suffer injury. Currently, safety seats typically allow rotation relative to the base to adjust their orientation and are secured to the base by a locking mechanism. However, the unlocking of existing locking mechanisms is cumbersome and provides a poor user experience. Utility Model Content

[0060] As living standards continue to improve, there are more and more children's products designed specifically for children, such as cribs and child safety seats. Among them, child safety seats are widely used because they can provide safety for children when traveling in a car. In the event of a frontal collision, a child in the vehicle will be thrown forward due to inertia. The safety device on the child safety seat can limit this forward movement. Without the protection of a child safety seat, the child could suffer certain injuries.

[0061] Currently, car seats typically rotate relative to their base and are secured to the base via a locking mechanism. This allows the car seat to be installed facing forward (children facing the direction of travel) or rear-facing (children facing away from the direction of travel). To improve the locking effect, two locking elements are usually installed on the base to position the ends of the car seat. However, existing locking mechanisms generally use two unlocking elements to unlock the two locking elements separately, which is cumbersome and results in a poor user experience.

[0062] Analysis of the causes of the above problems shows that the existing locking mechanism requires the operation of two unlocking parts to unlock the two locking parts separately, which makes the unlocking process cumbersome. To solve the problem of cumbersome unlocking, the structure of the locking mechanism needs to be improved so that any unlocking part can unlock both locking parts.

[0063] Based on this, this utility model proposes a linkage unlocking structure for children's products, aiming to solve the problem of cumbersome unlocking of existing locking mechanisms in children's products. Specifically, Figures 1 to 7 A schematic diagram of the linkage unlocking structure provided by this utility model; Figure 8 A schematic diagram of the structure of the children's product provided by this utility model.

[0064] Please see Figures 1 to 3 In one embodiment of this utility model, the linkage unlocking structure 100 includes a main body 1, a first locking member 21, a first unlocking member 22, a second locking member 31, a second unlocking member 32, and a synchronous transmission mechanism 4. The first locking member 21 is movably installed on the main body 1, and the first unlocking member 22 is movably disposed on the main body and is drivenly connected to the first locking member 21. When the first unlocking member moves toward the unlocking position, the first locking member 21 is unlocked. The second locking member 31 is movably installed on the main body 1, and the second unlocking member 32 is movably disposed on the main body and is drivenly connected to the second locking member 31. When the second unlocking member moves toward the unlocking position, the second locking member 31 is unlocked. The synchronous transmission mechanism 4 is disposed between the first unlocking member 22 and the second unlocking member 32 to enable the first unlocking member 22 and the second unlocking member 32 to move synchronously.

[0065] The main body 1 refers to a structure that allows for the installation of movable parts of a child safety device. For example, when the child safety device is a child safety seat, the main body 1 is the base of the child safety seat, and the movable part is the mounting seat that is movably installed on the base. Therefore, the main body 1 needs to have a certain strength and hardness. Its material can be various, such as metals like iron and aluminum, inorganic non-metallic materials like ceramics, or polymer materials like plastics. This invention does not limit this. Furthermore, the shape of the main body 1 can be various; it can be circular, rectangular, elliptical, etc. This invention does not limit this.

[0066] The first locking member 21 and the second locking member 31 are components used to position the movable parts of the child-use 1000 on the main body 1. They can be made of various materials, such as metals like iron and aluminum, inorganic non-metallic materials like ceramics, or polymer materials like plastics; this invention does not limit their materials. Furthermore, the first locking member 21 and the second locking member 31 can have various shapes, such as circular, rectangular, or polygonal; this invention does not limit their shapes. Furthermore, in order for the first locking member 21 and the second locking member 31 to restrict the movement of the movable parts of the child-use 1000, the movable parts of the child-use 1000 are provided with a first mating groove and a second mating groove. The first mating groove and the second mating groove are respectively provided corresponding to the first locking member 21 and the second locking member 31, so as to cooperate with the first locking member 21 and the second locking member 31 to lock or unlock the movable parts of the child-use 1000.

[0067] The synchronous transmission mechanism 4 is disposed between the first unlocking member 22 and the second unlocking member 32 to transmit the movement of the first unlocking member 22 or the first locking member 21 to the second unlocking member 32 or the second locking member 31, so that the first locking member 21 and the second locking member 31 can unlock synchronously.

[0068] The technical solution of this utility model, by setting the main body 1 to house the first locking member 21 and the second locking member 31, positions the movable part of the child-use 1000 on the main body 1, thereby preventing the movable part of the child-use 1000 from rotating. By setting the first unlocking member 22, the first locking member 21 is driven to release the lock on the movable part. By setting the second unlocking member 32, the second locking member 31 is driven to release the lock on the movable part. Simultaneously, by setting the synchronous transmission mechanism 4, the movement of the first unlocking member 22 or the first locking member 21 is transmitted to the second unlocking member 32 or the second locking member 31, so that the first unlocking member 22 or the second unlocking member 32 can drive the first locking member 21 and the second locking member 31 to move, so that the first locking member 21 and the second locking member 31 unlock synchronously, allowing the movable part of the child-use to rotate relative to the main body, thereby solving the problem of cumbersome unlocking of existing locking mechanisms.

[0069] In one embodiment of this utility model, please refer to Figure 1 and Figure 3The main body 1 serves as a base for mounting a seat device. The first locking member 21 and the second locking member 31 are movably disposed vertically. In the locked position, the first locking member 21 and the second locking member 31 protrude upwards from the upper surface of the main body 1. In the unlocked position, the first locking member 21 and the second locking member 31 are housed within the main body 1. When it is necessary to lock the movable part of the child-friendly device 100, the first locking member 21 and the second locking member move upwards to protrude from the upper surface of the main body 1 to restrict the relative rotation of the movable part. When it is not necessary to lock the movable part of the child-friendly device 100, the first locking member 21 and the second locking member move downwards to be housed within the main body 1 to release the restriction on the movable part. Thus, through the movement of the first locking member 21 and the second locking member 31, the relative rotation between the movable part and the base can be restricted, and the restriction on the movable part can be released, allowing the movable part to rotate relative to the base.

[0070] It should be noted that the first locking member 21 and the second locking member 31 may be rotatably mounted on the main body 1 or linearly movable mounted on the main body 1, etc. This utility model does not limit this.

[0071] In one embodiment of this utility model, please refer to Figures 1 to 4 The first unlocking member 22 has a first button, part of which is exposed outside the main body 1 to form a first operating part. The second unlocking member 32 has a second button, part of which is exposed outside the main body to form a second operating part. The first operating part and the second operating part are located opposite each other on the left and right sides of the main body 1. Thus, by setting the first button and the second button to form the first operating part and the second operating part respectively, it is convenient for the user to operate the first unlocking member 22 and the second unlocking member 32 to drive the first locking member 31 and the second locking member 32 to move in the up and down direction.

[0072] It should be noted that the first unlocking component 22 and the second unlocking component 32 can be configured in various ways. The first unlocking component 22 and the second unlocking component 32 can be unlocking buttons or unlocking knobs; this utility model does not limit this. Furthermore, the first unlocking component 22 and the second unlocking component 32 can be made of various materials, including metals such as iron and aluminum, inorganic non-metallic materials such as ceramics, and polymer materials such as plastics; this utility model does not limit this either.

[0073] In one embodiment of this utility model, both the first button and the second button are slidably arranged in the left-right direction. The linkage unlocking structure 100 further includes a first transmission structure 23 and a second transmission structure 33. The first transmission structure 23 is tractively connected between the first button and the first locking member 21 so that when the first button moves in the left-right direction, it drives the first locking member 21 to move in the up-down direction. The second transmission structure 33 is tractively connected between the second button and the second locking member 32 so that when the second button moves in the left-right direction, it drives the second locking member 32 to move in the up-down direction. The synchronous transmission mechanism 4 is tractively connected between the first button and the second button.

[0074] In this embodiment, by setting the first transmission structure 23 and the second transmission structure 33, the linear movement of the first button and the second button in the left and right directions is respectively converted into the linear movement of the first locking member 21 and the second locking member 31 in the up and down directions. By setting the first button and the second button that move in the left and right directions, the first locking member 21 and the second locking member 31 are respectively driven to move downward to be housed in the main body, so as to release the restriction on the moving parts of the child plaything 1000.

[0075] In order for the first unlocking member 22 to drive the first locking member 21 to unlock, in one embodiment of this utility model, please refer to... Figures 2 to 4 The first transmission structure 23 includes a first driving inclined surface 231 disposed on the first button, and a first engaging part disposed on the first locking member 21 that cooperates with the first driving inclined surface 231. The first driving inclined surface 231 is inclined downward, and the first engaging part can slide along the first driving inclined surface so that when the first button moves inward, the first driving inclined surface 231 abuts against the first engaging part and drives the first locking member 21 to move downward. Thus, by setting the first driving inclined surface 231 and the first engaging part to cooperate with each other, when the first button moves inward in the left and right direction towards the main body, the first locking member 21 is driven to move in the up and down direction, so that the first button moving in the left and right direction can drive the first locking member 21 moving in the up and down direction to move downward.

[0076] Of course, there are multiple ways in which the first unlocking member 22 drives the locking member 21 to move. In another embodiment, the first transmission structure 23 includes a first locking member guide surface disposed on the first locking member 21, and the first button is provided with a first button engaging part that cooperates with the first locking member guide surface. The first locking member guide surface is inclined upwards, and the first button engaging part can slide along the first locking member guide surface so that when the first button moves inwards, the first button engaging part abuts against the first locking member guide surface and drives the first locking member 21 to move downwards.

[0077] In order to enable the second unlocking member 32 to drive the second locking member 31 to unlock, in one embodiment of the present invention, the second transmission structure 33 includes a second driving inclined surface 331 disposed on the second button, and the second locking member 31 is provided with a second mating part that cooperates with the second driving inclined surface 331. The second driving inclined surface 331 is inclined downward, and the second mating part can slide along the second driving inclined surface 331 so that when the second button moves inward, the second driving inclined surface 331 abuts against the second mating part and drives the second locking member 31 to move downward. Thus, by setting the mutually cooperating second driving inclined surface 331 and the second mating part, when the second button moves inward in the left and right direction towards the main body, the second locking member 31 is driven to move in the up and down direction, so that the second button moving in the left and right direction can drive the second locking member 31 moving in the up and down direction to move downward.

[0078] Of course, there are various ways in which the second unlocking member 32 drives the locking member 31 to move. In another embodiment, the second transmission structure 33 includes a second locking member guide surface disposed on the second locking member 31, and the second button is provided with a second button engaging part that cooperates with the second locking member guide surface. The second locking member guide surface is inclined upward, and the second button engaging part can slide along the second locking member guide surface so that when the second button moves inward, the second button engaging part abuts against the second locking member guide surface and drives the second locking member 31 to move downward.

[0079] To facilitate the configuration of the first driving ramp 231, please refer to [reference needed] in this embodiment. Figure 2 and Figure 3The first transmission structure 23 further includes a first latching protrusion 232 disposed on the first locking member 21 and a first latching groove 233 disposed on the first button and cooperating with the first latching protrusion 232. The inner wall surface of the first latching groove 233 is inclined to form the first driving inclined surface 231. The first mating part includes the first latching protrusion 232. Thus, by setting the mutually cooperating first latching protrusion 232 and first latching groove 233, on the one hand, the left-right upward movement can be converted into a up-down upward movement, and on the other hand, the first unlocking member 22 can be prevented from disengaging from the first locking member 21, so that the first unlocking member 22 can drive the first locking member 21 to reciprocate. It is understood that there are multiple types of the first transmission structure 23. In other embodiments, the first transmission structure 23 includes a first through hole disposed on the first locking member 21. The first unlocking member 22 has a first driving end passing through the first through hole, and the first driving inclined surface 231 is disposed on the first driving end. Thus, when the first unlocking member 22 moves in the left-right direction, the first driving inclined surface 231 can drive the first locking member 21 to move in the up-down direction.

[0080] To facilitate the setting of the second driving inclined surface 331, in this embodiment, the second transmission structure 33 further includes a second latching protrusion 332 disposed on the second locking member 31 and a second latching groove 333 disposed on the second button and cooperating with the second latching protrusion 332. The inner wall surface of the second latching groove 333 is inclined to form the second driving inclined surface 331. The second mating part includes the second latching protrusion 332. Thus, by setting the mutually cooperating second latching protrusion 332 and second latching groove 333, on the one hand, the left-right upward movement can be converted into the up-down upward movement, and on the other hand, the second unlocking member 32 can be prevented from disengaging from the second locking member 31, so that the second unlocking member 32 can drive the second locking member 31 to reciprocate. It is understood that there are multiple types of the second transmission structure 33. In other embodiments, the second transmission structure 33 includes a second through hole provided in the second locking member 31, and the second unlocking member 32 has a second driving end passing through the second through hole. The second driving inclined surface 331 is provided in the second driving end. Thus, when the second unlocking member 32 moves in the left and right direction, the second driving inclined surface 331 can drive the second locking member 31 to move in the up and down direction.

[0081] It should be noted that the above two related technical features, namely, "the first transmission structure 23 further includes a first latching protrusion 232 disposed on the first locking member 21 and a first latching groove 233 disposed on the first button and cooperating with the first latching protrusion 232" and "the second transmission structure 33 further includes a second latching protrusion 332 disposed on the second locking member 31 and a second latching groove 333 disposed on the second button and cooperating with the second latching protrusion 332", can be provided in one or both, and this utility model does not limit them in this regard.
