Description

Technical Field

[0001] This application relates to the field of children's vehicles, and more particularly to an unlocking device and a children's vehicle. Background Technology

[0002] In the stroller industry, the design of the frame's folding and unlocking mechanism has always been a key aspect of product development and innovation. Traditional stroller frame folding methods are complex and cumbersome, often requiring the user to use both hands and go through multiple steps to complete the folding process, which undoubtedly brings many inconveniences to users' daily use. Especially when going out or traveling, a stroller with a simple and quick folding process can reduce the trouble of carrying and storing it.

[0003] Existing stroller frame unlocking and folding technologies still have many shortcomings. Although some technologies can achieve the folding function of the frame, the unlocking process is still relatively cumbersome, requiring users to perform multiple operations to complete all the unlocking and folding steps. This not only reduces the user experience, but also limits the portability and practicality of the stroller to a certain extent. Utility Model Content

[0031] This application uses a pull rope to drive the drive component to rotate, which in turn drives the locking component to move axially along the rotating shaft under the transmission structure. The locking component is then pushed from the first shell to the second shell, thereby releasing the locking of the first shell. At this time, the first shell and the second shell are no longer locked and limited by the locking component, so the first shell and the second shell can rotate relative to each other, thus achieving unlocking.

[0053] This application provides an unlocking device 100, which includes a first housing 110, a second housing 120, a driving member 130, a snap-fit ​​member 140, an elastic member 150, a pull rope 160, and a transmission structure 170.

[0054] In some embodiments, the first housing 110 has a first cavity 111, and the second housing 120 is located on one side of the first housing 110. The second housing 120 is rotatably connected to the first housing 110, and the first housing 110 and the second housing 120 define a receiving cavity. A rotating shaft 121 is provided in the axial direction of the second housing 120. A driving member 130 is rotatably disposed within the receiving cavity through the rotating shaft 121. A snap-fit ​​member 140 is located on one side of the driving member 130, passes through the rotating shaft 121, and is disposed within the receiving cavity. The snap-fit ​​member 140 is partially snapped into the first housing 110 circumferentially. The other part of the snap-fit ​​140 away from the first housing 110 is circumferentially snapped with the second housing 120. The elastic element 150 is sleeved on the rotating shaft 121. One end of the elastic element 150 abuts against the end face of the snap-fit ​​140 away from the driving element 130, and the other end of the elastic element 150 away from the snap-fit ​​140 abuts against the side wall of the rotating shaft 121. One end of the pull rope 160 is set on the driving element 130. Pulling the pull rope 160 drives the driving element 130 to rotate. The transmission structure 170 is located in the receiving cavity. The rotation of the driving element 130 is moved toward the snap-fit ​​140 through the transmission structure 170.

[0055] See Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, in the initial state, a portion of the latching member 140 is located in the first housing 110 and latched against its inner circumferential surface, while the other portion is located in the second housing 120 and latched against its inner circumferential surface. Therefore, the first housing 110 and the second housing 120 are fixed in position by the latching member 140, and they cannot rotate relative to each other. Further, in this embodiment, during unlocking, the first housing 110 and the second housing 120 can rotate relative to each other via the pivot 121. It can be understood that the pivot 121 is the center of rotation between the first housing 110 and the second housing 120.

[0056] Please continue reading. Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, when it is necessary to unlock the first shell 110 and the second shell 120 so that they can rotate relative to each other, firstly, the pull rope 160 can be manually pulled to drive the drive member 130 to rotate a certain angle. Under the function of the transmission structure 170, the drive member 130 is driven to move along the rotating shaft 121 toward the second shell 120. Then, the drive member 130 abuts against the latching member 140 and drives the latching member 140 to move axially toward the second shell 120 along the rotating shaft 121. As the position of the latching member 140 moves, the latching member 140 gradually exits from the first shell 110 until it is completely inserted into the second shell 120. When the latching member 140 is completely inserted into the second shell 120, the first shell 110 and the second shell 120 are no longer limited by the latching member 140. Therefore, the first shell 110 and the second shell 120 can rotate along the rotating shaft 121 to achieve unlocking.

[0057] Understandably, when it is necessary to lock the first shell 110 and the second shell 120, it is only necessary to loosen the pull cord 160. The elastic element 150 drives the locking member 140 to move toward the first shell 110, so that part of the locking member 140 re-enters the first shell 110 and engages with the inner circumferential surface of the first shell 110. At this time, the first shell 110 and the second shell 120 are once again engaged by the locking member 140 and cannot rotate relative to each other. Therefore, the first shell 110 and the second shell 120 are locked again. As can be seen from the above description, during the unlocking and locking process of the first shell 110 and the second shell 120, the locking member 140 is always engaged with the inner circumferential surface of the second shell 120.

[0058] In this embodiment, the elastic element 150 can be a spring, specifically a compression spring.

[0059] The first housing 110 has a first cavity 111 on the side facing the second housing 120, and the second housing 120 has a second cavity 122 on the side facing the first housing 110. A rotating shaft 121 is fixedly disposed on the axial inner wall of the second cavity 122 and extends into the first cavity 111. The second cavity 122 communicates with the first cavity 111 to form a receiving cavity.

[0060] See Figure 2 , Figure 3 , Figure 5 as well as Figure 6 As shown, in order to install the drive member 130 and the snap-fit ​​member 140, the first housing member 110 has a first cavity 111 on its side wall, and the second housing member 120 has a second cavity 122 on its side wall. The first cavity 111 and the second cavity 122 are connected to form a receiving cavity, and the rotating shaft 121 extends into the first cavity 111. The first housing member 110 is rotatably connected to the rotating shaft 121, so that the first housing member 110 and the second housing member 120 can rotate relative to each other.

[0061] The transmission structure 170 includes a first abutting block 171 fixedly disposed on the axial inner wall of the first cavity 111. The first abutting block 171 has an abutting slope. The outer surface of the driving member 130 is provided with a second abutting block 172 adapted to the first abutting block 171. The second abutting block 172 abuts against the abutting slope of the first abutting block 171.

[0062] See Figure 4 , Figure 5 as well as Figure 7 As shown, in order to enable the drive engagement 140 to move along the shaft 121 toward the second housing 120 via the rotation of the drive member 130, at least one first abutment block 171 is fixedly provided on the end face (axial end face) of the first housing cavity 111, and a second abutment block 172 adapted to the first abutment block 171 is provided on the outer surface of the drive member 130, and the first abutment block 171 and the second abutment block 172 abut against each other. It can be understood that when the drive member 130 is rotated by the pull rope 160, the second abutment block 172 abuts against the first abutment block 171. With both the connecting block 171 and the second abutting block 172 being inclined or curved surfaces, the driving member 130 also moves axially along the rotating shaft 121 during rotation. The axial movement of the driving member 130 overcomes the elastic force of the elastic member 150 and drives the locking member 140 to move toward the second shell 120 until the locking member 140 is completely inside the second shell cavity 122. At this time, the locking member 140 is no longer located in the first shell 110, so the locking member 140 is no longer locked with the inner circumferential surface of the first shell 110. The first shell 110 and the second shell 120 can rotate relative to each other to achieve unlocking.

[0063] The outer surface of the drive component 130 is also provided with an abutment groove 173, which abuts against the abutment slope of the first abutment block 171.

[0064] Please continue reading. Figure 7 As shown, in order to further improve transmission efficiency, an abutment groove 173 adapted to the first abutment block 171 can be formed on the outer peripheral surface of the drive member 130. The abutment surface of the abutment groove 173 and the first abutment block 171 is a slope or an arc surface, which can be adapted to the same abutment shape as the first abutment block 171. It should be noted that in this embodiment, there are multiple first abutment blocks 171, second abutment blocks 172 and abutment grooves 173. The specific number can be designed according to actual needs and is not limited here.

[0065] The outer surface of the snap-fit ​​component 140 has at least one snap tooth 141, the inner wall of the peripheral surface of the first cavity 111 has at least one first slot 112, and the inner wall of the peripheral surface of the second cavity 122 has at least one second slot 123. The snap tooth 141 extends into the first slot 112 and the second slot 123.

[0066] See Figure 4 , Figure 5 , Figure 6 as well as Figure 8 As shown, in order to enable the snap-fit ​​member 140 to move axially without rotating and to engage with the first shell 110 and the second shell 120 for circumferential limiting, multiple snap-fit ​​teeth 141 are formed on the outer surface of the snap-fit ​​member 140. A first slot 112 that can engage with the snap-fit ​​teeth 141 is formed on the inner circumferential surface of the first shell cavity 111, and a second slot 123 that can engage with the snap-fit ​​teeth 141 is formed on the inner circumferential surface of the second shell cavity 122. That is, in the initial state of locking the first shell 110 and the second shell 120, the snap-fit ​​teeth 141 engage with the first slot 112 and the second slot 123 simultaneously, thereby achieving axial limiting of the first shell 110 and the second shell 120, and preventing them from rotating relative to each other.

[0067] A limiting groove 142 is formed on the end face of the snap-fit ​​member 140 facing away from the drive member 130, and a portion of the elastic member 150 extends into the limiting groove 142.

[0068] Please continue reading. Figure 8 As shown, in order to prevent the central axis of the elastic member 150 from shifting, a limiting groove 142 is provided on the end face of the snap fastener 140 facing the elastic member 150. That is, the limiting groove 142 is provided on the contact surface between the snap fastener 140 and the elastic member 150, so that part of the elastic member 150 is inserted into the limiting groove 142 to limit the position of the elastic member 150 and prevent it from shifting.

[0069] The inner wall of the first shell cavity 111 has a through hole 113 that communicates with the outside, and the pull rope 160 passes through the through hole 113 to the outside of the first shell 110.

[0070] See Figure 5 As shown, in order to enable the drive component 130 to be stretched and rotated externally via the pull rope 160, a through hole 113 communicating with the outside is opened on the inner wall of the first cavity 111. The stretching end of the pull rope 160 extends to the outside through the through hole 113. Figure 5 It is understandable that the first housing 110 is fixedly connected to a hollow connecting tube, and the pull rope 160 passes through the through hole 113 to the inside of the connecting tube and extends further to the outside.

[0071] The drive component 130 has a mounting hole 131 on its end face and a clearance hole 132 on its circumferential surface that communicates with the mounting hole 131. The end of the pull rope 160 is fixedly connected to a connecting block 161, which extends into the mounting hole 131 and passes through the clearance hole 132.

[0072] Please see Figure 3 and Figure 7As shown, in order to connect the pull rope 160 to the drive member 130 and drive the drive member 130 to rotate, a connecting block 161 is fixedly connected to the end of the connecting block 161. A mounting hole 131 adapted to the connecting block 161 is opened on the end face of the drive member 130. The connecting block 161 extends into the mounting hole 131 to complete the installation of the connecting block 161. In order to prevent the pull rope 160 from being located at the end face of the drive member 130, a clearance hole 132 is opened on the outer peripheral surface of the drive member 130. The pull rope 160 extends to the outside through the clearance hole 132 and the through hole 113.

[0073] Please continue reading. Figure 3 and Figure 4 As shown, a cover plate 124 is provided on the end face of the second shell 120 away from the first shell 110. The cover plate 124 closes the outer end face of the second shell 120, making the overall appearance more aesthetically pleasing.

[0074] See Figure 9 , Figure 10 , Figure 11 as well as Figure 12 As shown in the embodiment of this application, a stroller is also provided, which includes the unlocking device 100, the first push handle 200, the side armrest 300, the second push handle 400, the rear footrest 500, the front footrest 600, and the seat bracket 700 of any of the above.

[0075] In some embodiments, the end of the first push handle 200 facing the unlocking device 100 is fixedly connected to the first housing 110, the end of the side armrest 300 facing the unlocking device 100 is fixedly connected to the second housing 120, the second push handle 400 is hinged to the first housing 110, a connector 410 is fixedly provided at one end of the second push handle 400 away from the first housing 110, the rear leg 500 is hinged to the second push handle 400, the front leg 600 is hinged to the rear leg 500 at the hinge position between the side armrest 300 and the rear leg 500, one end of the seat bracket 700 is hinged to the front leg 600, and one end of the seat bracket 700 away from the front leg 600 is hinged to the connector 410.

[0076] It should be noted that the seat support 700 is composed of a first link frame 710 and a second link frame 720. The first link frame 710 and the second link frame 720 are hinged together. The end of the first link frame 710 away from the second link frame 720 is hinged to the connector 410. The end of the second link frame 720 away from the first link frame 710 is hinged to the front footrest 600.

[0077] Please continue reading. Figures 9 to 12As shown, when the stroller needs to be folded as a whole, firstly, the drive unit 130 is rotated by pulling the cord 160, which unlocks the first shell 110 and the second shell 120. After unlocking, the first push handle 200, which is fixedly connected to the first shell 110, and the side armrest 300, which is fixedly connected to the second shell 120, can rotate relative to each other.
