Technical Field
[0001] This invention relates to the technical field of children's products, and more particularly to a novel locking device and a stroller having the novel locking device. Background Technology
[0002] Strollers are a baby's "transportation tool," requiring someone to push or pull them. In the market, strollers can be broadly categorized by function into luxury models suitable for general home use and extended outings, lightweight models suitable for frequent trips, and tricycles for the convenience of caregivers during outdoor activities.
[0003] Strollers are typically equipped with child seats, carriers, and other child carriers for children's use. Existing strollers generally have a detachable locking mechanism for installing child seats and other child carriers. When users remove the child carriers, they usually need to check the fixing points on the stroller, remove the latches on the fixing points, and then operate some buttons to remove the child carriers from the stroller. The process is complicated and cumbersome, and it is not conducive to quickly changing to different child carriers.
[0004] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention
[0005] This invention addresses the problems mentioned above regarding the complex disassembly process, cumbersome operation, and difficulty in quickly changing between different children's vehicles in existing detachable locking mechanisms for strollers. It proposes a novel locking device and a stroller with the novel locking device.
[0006] The technical solution adopted by this invention to solve its technical problem is:
[0007] A novel locking device includes: a first mounting portion and a second mounting portion, respectively disposed on both sides of the locking device; the first mounting portion is used to connect to a child carrier, and the second mounting portion is used to connect to a vehicle frame; a first locking assembly for locking and securing the child carrier; a first unlocking drive assembly connected to the first locking assembly, the first unlocking drive assembly being used to switch the first locking assembly from a locked state to an unlocked state relative to the child carrier; and a linkage reset assembly connected to the first locking assembly, the linkage reset assembly being able to reset the first locking assembly from an unlocked state to a locked state; when the first locking assembly is in an unlocked state, the linkage reset assembly is used to keep the first locking assembly in an unlocked state and prevent the first locking assembly from switching to a locked state.
[0008] As described above, a novel locking device includes a first housing. The first locking assembly includes a movable member that is vertically and elliptically disposed within the first housing and a first slot disposed in the movable member and facing outward from the first housing. The first housing has a second slot communicating with the first slot. The movable member is driven to move downward within the first housing by the first unlocking drive assembly, thereby causing the first slot to move downward relative to the second slot, so that the first slot and the second slot are misaligned, thereby causing the first locking assembly to switch to an unlocked state.
[0009] As described above, in a novel locking device, a first elastic element connected to a movable member is provided inside the first housing. The first elastic element is used to move the movable member upward and reset it within the first housing, and drive the first slot to move upward relative to the second slot until it is aligned with the second slot, so that the first locking assembly is switched to a locked state.
[0010] As described above, in a novel locking device, the first unlocking drive component includes a first unlocking button that is vertically mounted in a first housing. The first unlocking button is connected to a movable component and is used to drive the movable component to move up and down within the first housing.

[0032] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0033] like Figure 1 As shown in Figure 11, the novel locking device provided by the present invention includes: a first mounting part 14 and a second mounting part 15, respectively disposed on both sides of the locking device 1; the first mounting part 14 is used to connect with a child carrier 3, and the second mounting part 15 is used to connect with a vehicle frame 2; a first locking assembly 11, used to lock and fix the child carrier 3; a first unlocking drive assembly 12, connected to the first locking assembly 11, the first unlocking drive assembly 12 being used to switch the first locking assembly 11 from a locked state to an unlocked state relative to the child carrier 3; and a linkage reset assembly 13, connected to the first locking assembly 11, the linkage reset assembly 13 being able to reset the first locking assembly 11 from an unlocked state to a locked state; when the first locking assembly 11 is in an unlocked state, the linkage reset assembly 13 is used to keep the first locking assembly 11 in an unlocked state and restrict the first locking assembly 11 from switching to a locked state.
[0034] like Figure 1 As shown in Figure 8, Figure 2 and Figure 7 The first locking component 11 is in the locked state. Figure 3 and Figure 8The first locking component 11 is in the unlocked state. In this embodiment, the locking device 1 is installed in a stroller for use. Child seats, child carriers, and other child vehicles 3 can be installed on the stroller through the locking device 1. This embodiment takes a child seat as an example. The first mounting part 14 is detachably connected to the child seat, and the child seat is locked and fixed by the first locking component 11 to make the child seat more stable when installed or removed. In practical applications, the first locking component 11 has a locked state and an unlocked state for the child seat. When the first locking component 11 is in the locked state, the child seat can be stably installed in the stroller for the child to use, thereby improving the child's safety and comfort and making it convenient for guardians to take the child out. When the user manually drives the first unlocking drive component 12, the first locking component 11 can be switched from the locked state to the unlocked state. At this time, the user can lift the child vehicle 3. The child carrier 3 can be detached by moving it upward relative to the frame 2. The first locking component 11 is kept in the unlocked state by the linkage reset component 13, so that the user can directly remove the child seat from the frame 2 for replacement with other child carriers 3 such as child carriers. The first locking component 11 is unlocked with one click by the first unlock drive component 12 and is detachably set by the first mounting part 14, so that the child carrier 3 can be easily removed. During the removal of the child carrier 3, the linkage reset component 13 can be switched from the unlocked state to the locked state by external force, so as to facilitate the quick installation and fixation of the child carrier 3. The operation is simple, time-saving and labor-saving, and convenient for users to change to different child carriers 3 as needed. Preferably, the locking device 1 is compatible with the installation of various child carriers 3, has strong versatility, does not require the configuration of additional adapter installation mechanism, and is convenient for daily use.
[0035] Specifically, the locking device 1 includes a first housing 16, and the first locking assembly 11 includes a movable member 111 movably disposed within the first housing 16, a first slot 112 disposed in the movable member 111 and facing outward from the first housing 16, and a second slot 161 communicating with the first slot 112 in the first housing 16. The first unlocking drive assembly 12 drives the movable member 111 to move downward within the first housing 16, causing the first slot 112 to move downward relative to the second slot 161, thus misaligning the first slot 112 with the second slot 161, thereby switching the first locking assembly 11 to an unlocked state. Further, the first housing 16 includes a first elastic member 113 connected to the movable member 111. The first elastic member 113 is used to move the movable member 111 upward within the first housing 16 to a reset position, and to cause the first slot 112 to move upward relative to the second slot 161 until aligned with the second slot 161, thereby switching the first locking assembly 11 to a locked state.
[0036] like Figure 2 and Figure 3 As shown, in this embodiment, the first housing 16 has a movable space within it for the movable component 111 to move up and down and to connect to the outside. The movable component 111 is installed in this movable space, with the first slot 112 and the second slot 161 facing the side of the child carrier 3, to facilitate direct connection of the child carrier 3. Preferably, the child carrier 3 is provided with a horizontally extendable slider. When the first locking component 11 is in the locked state, the first slot 112 and the second slot 161 are aligned and joined to form a positioning groove 101. This positioning groove 101 is connected to the child carrier 3. The slider is adapted to the positioning groove 101 so that the slider can be fixed in the positioning groove 101, thereby locking the child carrier 3 with the first locking assembly 11. More preferably, a second groove 161 is provided on both sides of the first groove 112. When the moving member 111 moves down in the first housing 16 through the first unlocking drive assembly 12, the moving member 111 drives the first groove 112 to move down relative to the second groove 161, so that the first groove 112 and the second groove 161 are misaligned. At this time, the first locking assembly 11 is in the unlocked state. Figure 2 and Figure 3As shown, preferably, the movable component 111 is provided with a first guide ramp 1121 located above the first slot 112. During the downward movement of the first slot 112, the slider is pushed by the first guide ramp 1121. At the same time, as the second slot 161 moves downward relative to the first slot 112, the wall in the first housing 16 located above the second slot 161 forms a second limiting part to prevent the slider from inserting into the positioning slot 101, so that the slider remains retracted towards the child carrier 3 to disengage from the positioning slot 101, thereby allowing the child carrier 3 to be unlocked and disassembled from the first locking assembly 11; moreover, the first housing A first elastic element 113 is provided inside the body 16. The first elastic element 113 is connected to the lower part of the moving member 111. When the linkage reset assembly 13 is released from the restriction of the first locking assembly 11 by external force, the moving member 111 can automatically move upward and reset within the first housing 16 through the first elastic element 113, so as to drive the first slot 112 to move upward relative to the second slot 161 until it is aligned with the corresponding second slot 161. This allows the slider to directly extend into the aligned first slot 112 and second slot 161 when the user reinstalls the child carrier 3, so that the child carrier 3 is fixed in the frame 2. Through the above settings, The user only needs to manually drive the first unlocking drive component 12 to unlock the first locking component 11, thereby allowing the child vehicle 3 to be detached from the frame 2. The operation is simple, convenient, and quick. Moreover, the first locking component 11 has a memory characteristic, automatically returning to a lockable state via the first elastic element 113. The design is ingenious and the structure is simple, making it easy to manufacture and implement. Preferably, the first elastic element 113 is a return spring, which is easy to obtain and has a low production cost. More preferably, the moving component 111 can be provided with a plurality of first slots 112, which are vertically spaced on the moving component 11. In step 1, the first housing 16 may be provided with a second slot 161 corresponding to each of the first slots 112. When the child carrier 3 is subjected to external force, it moves up and down relative to the locking device 1, and drives the slider to move up and down relative to the first slot 112 and the second slot 161. When the first locking component 11 is in the locked state, the first slot 112 and the second slot 161 are aligned and form a positioning groove 101 that is engaged and fixed with the slider. By setting multiple levels of the first slot 112 and the second slot 161, the installation height of the child carrier 3 can be adjusted, thereby increasing the functionality of the frame 2 and further optimizing the user experience.
[0037] Furthermore, the first unlocking drive assembly 12 includes a first unlocking button 121 that is vertically mounted in the first housing 16. The first unlocking button 121 is connected to the moving member 111, and the first unlocking button 121 is used to drive the moving member 111 to move up and down in the first housing 16. Figure 7 and Figure 8 As shown, in this embodiment, the first unlock button 121 is connected to the upper part of the moving member 111 and close to the top of the first housing 16. The first unlock button 121 is exposed on the side facing the human body for easy operation. Manually driving the first unlock button 121 downwards within the first housing 16 moves the moving member 111 downwards within the first housing 16, causing the first locking assembly 11 to switch from a locked state to an unlocked state, achieving one-button unlocking. This operation is simple, time-saving, and labor-saving. During reset, the moving member 111 is reset upwards within the first housing 16 via the first elastic element 113, moving the first unlock button 121 upwards to reset, enabling the first unlock button 121 to automatically reset, simplifying operation and further optimizing the user experience. In other embodiments, the first unlock button 121 and the moving member... The 111 is a one-piece molded structure, which enhances the overall structural stability of the first unlock button 121 and the moving component 111. The structure is simple and easy to manufacture, thus improving production efficiency. More preferably, the first unlock button 121 has a first connecting part 1211, and the first housing 16 has a second connecting part 163 corresponding to the first connecting part 1211. The first connecting part 1211 is slidably inserted into the second connecting part 163 to achieve a liftable connection of the first unlock button 121. This structure is simple and easy to manufacture. In other embodiments, the first connecting part 1211 is configured as a groove or a plate, and the second connecting part 163 is correspondingly configured as a plate or a groove. The depth of the groove is greater than the height of the plate, providing sufficient movement space for the lifting and lowering process of the first unlock button 121.
[0038] Specifically, the linkage reset assembly 13 includes a locking rod 131 connected to the moving member 111 and a second elastic member 132 disposed between the locking rod 131 and the moving member 111. The first housing 16 is provided with a first limiting part 162 corresponding to the locking rod 131. The moving member 111 moves downward within the first housing 16 through the first unlocking drive assembly 12 to drive the locking rod 131 to move downward relative to the first limiting part 162. The locking rod 131 is ejected by the second elastic member 132 to abut against the bottom of the first limiting part 162. The first locking assembly 11 is kept in the unlocked state by the first limiting part 162. Furthermore, the first limiting part 162 includes a baffle 1621 disposed in the first housing 16 and near the top of the first housing 16, and a limiting groove 1622 for accommodating the locking rod 131. The limiting groove 1622 is disposed inside the first housing 16. The lower part of the baffle 1621 is also provided with a spring outlet 1623 communicating with the limiting groove 1622. When the locking rod 131 moves downward relative to the baffle 1621 through the moving member 111, the locking rod 131 is ejected through the spring outlet 1623 by the second elastic member 132 and abuts against the bottom of the baffle 1621.
[0039] like Figure 4 , 5As shown in Figures 7 and 8, in this embodiment, the locking rod 131 is installed on the upper part of the moving member 111 and located on one side of the first unlocking button 121. Preferably, the locking rod 131 is pivotally connected to the moving member 111 so that the locking rod 131 can rotate relative to the moving member 111 to a certain extent. A second elastic element 132 is provided between the locking rod 131 and the moving member 111. When the first locking assembly 11 is in the locked state, the first slot 112 and the second slot 161 are aligned. At this time, the locking rod 131 is placed in the limiting slot 1622 and abuts against the inner wall of the baffle 1621 so that the second elastic element 132 stores energy. When the first locking assembly 11 is switched to the unlocked state, the moving member 111 moves down in the first housing 16 and drives the locking rod 131 to rotate. 31 moves down relative to the baffle 1621 to the ejection outlet 1623. At this time, the locking rod 131 is ejected outward by the elastic force of the second elastic member 132, and the top of the locking rod 131 abuts against the bottom of the baffle 1621 to restrict the moving member 111 from resetting through the first elastic member 113, thereby keeping the first locking assembly 11 in the unlocked state so that the user can better disassemble the child carrier 3. The linkage reset assembly 13 has a simple overall structure and is easy to manufacture and implement. More preferably, the second elastic member 132 is a torsion spring, which is easy to obtain, has low production cost, and is easy to assemble. The limiting groove 1622 is preferably set as part of the moving space inside the first housing 16, which simplifies the structure of the first limiting part 162 and reduces production cost.
[0040] Furthermore, a protrusion 1311 is provided on the outer side of the locking rod 131, and a first guide portion 1312 is provided at the bottom of the protrusion 1311. When the locking rod 131 is ejected by the second elastic member 132, the protrusion 1311 follows the locking rod 131 and ejects to the outer side of the baffle 1621. The first guide portion 1312 can be subjected to external force to retract the locking rod 131 into the limiting groove 1622. As shown in 2, 3, 7, and 8, in this embodiment, when the first locking assembly 11 is in the unlocked state, the user can directly remove the child carrier 3 by lifting it upward relative to the frame 2. At this time, the locking rod 131 abuts against the bottom of the baffle 1621, and the protrusion 1311 is located on the outside of the baffle 1621. During the upward movement of the child carrier 3, the child carrier 3 contacts the protrusion 1311. The protrusion 1311 is pushed by the child carrier 3 and guided by the first guide part 1312 to rotate in the opposite direction and retract into the limiting groove 1622. At this time, the moving member 111... The first elastic element 113 can drive the locking rod 131 to move upward and reset, so that the first locking assembly 11 changes from the unlocked state to the locked state, which facilitates the quick installation of the child carrier 3. The operation is simple and does not require additional reset operation, saving time and effort in daily use, thereby optimizing the user experience. More preferably, a second guide part corresponding to the first guide part 1312 can be provided on the side of the child carrier 3 opposite to the protrusion 1311, thereby ensuring the smooth operation of the first guide part 1312. The first guide part 1312 and the second guide part are preferably set as compatible guide ramps, which are simple in structure and easy to manufacture and implement.
[0041] like Figure 9 As shown in Figure 11, the present invention also provides a stroller with a novel locking device, comprising a frame 2 and a child carrier 3. The frame 2 includes a locking device 1 as described above, and the child carrier 3 is connected to the frame 2 via the locking device 1. The child carrier 3 includes a third mounting portion 31 corresponding to and connected to the first mounting portion 14, and the frame 2 further includes a fourth mounting portion 21 corresponding to and connected to the second mounting portion 15. Furthermore, the locking device 1 includes a second unlocking drive assembly 17 for unlocking the second mounting portion 15 from the fourth mounting portion 21, and the second unlocking drive assembly 17 is connected to the second mounting portion 15.
[0042] like Figure 1 , 2As shown in Figures 3, 10, and 11, in this embodiment, the child carrier 3 is detachably connected to the locking device 1 by correspondingly inserting the third mounting part 31 into the first mounting part 14; the locking device 1 is detachably installed on the frame 2 by correspondingly inserting the second mounting part 15 into the fourth mounting part 21. Specifically, the first mounting part 14 is located on the same side as the first slot 112 and the second slot 161. The first mounting part 14 includes protrusions 141 respectively disposed on the left and right sides of the side of the first housing 16. The two protrusions 141 are spaced apart from the first housing 16 and form a first receiving space 142. The third mounting part 31 includes first connecting sections 311 respectively disposed on the left and right sides of the side of the child carrier 3. The two first connecting sections 311 are arranged opposite each other, and each end of the two first connecting sections 311 is provided with a second connecting section 312. The two second connecting sections 312 extend towards each other at a certain distance and are spaced apart.

The first mounting portion 142 is used to accommodate two second connecting segments 312 respectively, and the second mounting portion 313 is used to accommodate the protrusion 141. More preferably, the bottom of the first mounting portion 14 is also provided with a support portion 164. During assembly, the second connecting segments 312 are movably inserted into the first mounting portion 142, and the protrusion 141 is movably inserted into the second mounting portion 313. The second connecting segments 312 and the protrusion 141 abut against each other to form a first blocking structure for limiting the relative lateral movement of the first mounting portion 14 and the third mounting portion 31. The third mounting portion 31 can be slidably inserted into the first mounting portion 14, so that the child carrier 3 can be slidably inserted into the locking device 1. The support portion 164 is used to limit the downward movement distance of the child carrier 3 relative to the locking device 1. The installation method of the first mounting portion 14 and the third mounting portion 31 is simple, easy to disassemble and assemble, and the structure is stable during use.
[0043] Furthermore, the second mounting part 15 and the first mounting part 14 are located on different sides. Specifically, the second mounting part 15 is located below the first unlock button 121. The second mounting part 15 includes a first slide rail part 151 and a second slide rail part 152 disposed opposite to each other. The fourth mounting part 21 is disposed in the frame 2 and corresponds to the second mounting part 15. The fourth mounting part 21 includes a second housing 211 connected to the frame 2, a locking block 214 laterally telescopically connected to the second housing 211, a third slide rail part 212 and a fourth slide rail part 213 disposed below the locking block 214. The structure of the third slide rail part 212 is the same as that of the first mounting part 14. The structure of the first slide rail 151 and the second slide rail 152 is similar to that of the third mounting part 31. During assembly, the first slide rail 151 and the third slide rail 212, the second slide rail 152 and the fourth slide rail 213 are respectively inserted into each other, and a second blocking structure is formed between the first slide rail 151 and the third slide rail 212, and the second slide rail 152 and the fourth slide rail 213. The second blocking structure is used to restrict the relative lateral movement of the second mounting part 15 and the fourth mounting part 21 to enhance the connection stability of the locking device 1. The installation method between the second mounting part 15 and the fourth mounting part 21 is simple and easy to disassemble and assemble.
[0044] Furthermore, the locking device 1 also includes a second unlocking drive assembly 17 for unlocking the fourth mounting portion 21 from the second mounting portion 15, the second unlocking drive assembly 17 being connected to the second mounting portion 15. For example... Figure 1 , 4As shown in Figures 5, 7, and 8, in this embodiment, to enhance the connection stability between the second mounting portion 15 and the fourth mounting portion 21, a second unlocking drive assembly 17 is provided. Specifically, the second unlocking drive assembly 17 is disposed in the first housing 16 and connected to the upper side of the second mounting portion 15. The second unlocking drive assembly 17 includes a second unlocking button 171 slidably connected in the first housing 16 and a third elastic member 172 disposed in the first housing 16 and connected to the second unlocking button 171. The second unlocking button 171 extends out of the first housing 16 for user operation, and a locking groove 173 adapted to the locking block 214 is formed between the lower part of the second unlocking button 171 and the first housing 16. The top of the locking block 214 is provided with a second guide slope 2141. During assembly, the second mounting portion 15 and the fourth mounting portion 21... The movable connection allows the locking device 1 to be detachably mounted on the frame 2. At this time, the locking block 214 is inserted into the locking groove 173. When the user manually presses the second unlocking button 171 to move down, the second guide slope 2141 guides the locking block 214 to retract inward toward the frame 2, so that the locking block 214 disengages from the locking groove 173. This allows the second mounting part 15 to move upward relative to the fourth mounting part 21, thereby removing the locking device 1 from the frame 2. The second unlocking drive assembly 17 has a simple overall structure, is easy to manufacture and implement, and is easy to operate, making the locking device 1 easy to assemble and disassemble. The third elastic element 172 is used to move the second unlocking button 171 upward to reset, so that the second unlocking button 171 can automatically reset, saving time and effort. Preferably, the third elastic element 172 is a spring, which is easy to obtain and has a low production cost.
[0045] Preferably, the locking device 1 further includes a positioning groove 101 located on the upper side of the first mounting portion 14. The positioning groove 101 has several portions and is spaced apart along the height direction of the locking device 1. The child carrier 3 also includes a slider that can extend and retract within and outside the third mounting portion 31, and the positioning groove 101 is adapted to the slider. Figure 2 and Figure 3As shown, in this embodiment, the positioning groove 101 is formed by combining the first groove 112 and the second groove 161, and the positioning groove 101 is adapted to the slider. Specifically, a plurality of first grooves 112 can be provided in the moving member 111, and the first grooves 112 are arranged vertically at intervals in the moving member 111. The first housing 16 can be provided with second grooves 161 corresponding to each of the first grooves 112. When the child carrier 3 is subjected to external force, it moves up and down relative to the locking device 1, and drives the slider to move up and down relative to the first grooves 112 and the second grooves 161. When the first locking assembly When 11 is in the locked state, the first slot 112 and the second slot 161 are aligned and form a positioning slot 101 that engages and is fixed to the slider. By setting multiple levels of the first slot 112 and the second slot 161, the child carrier 3 can be adjusted in height in the stroller, thereby increasing the functionality of the frame 2 and further optimizing the user experience. When the child carrier 3 is subjected to external force and moves up and down relative to each positioning slot 101, the third mounting part 31 slides into the first mounting part 14, enhancing the stability of the child carrier 3 in adjusting its installation height, making it less likely to fall off, and thus protecting the child's safety.
