Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0031] The embodiments of this application will now be described in detail. In this application, "front" refers to the direction the child faces when sitting in the car seat, "rear" refers to the direction the child faces away from when sitting in the car seat, "above" refers to the direction near the child's head when sitting in the car seat, and "below" refers to the direction near the child's feet when sitting in the car seat.

[0032] like Figure 1 As shown, this application provides a child safety seat installation device, including an ISOFIX assembly 10, a button assembly 20, and a wireless communication module 30. The button assembly 20 is fixed to the ISOFIX assembly 10, and the wireless communication module 30 is disposed on the button assembly 20. The child safety seat installation device has a locked state and an unlocked state. In the locked state, the child safety seat installation device is locked to the vehicle seat, realizing the installation of the child safety seat. In the unlocked state, the child safety seat installation device is separated from the vehicle seat, realizing the removal of the child safety seat.

[0033] Please refer to the following at the same time Figure 2 The ISOFIX assembly 10 includes a base 11 and a connecting bracket 12, the connecting bracket 12 being slidably mounted on the base 11. The connecting bracket 12 includes a housing 121, a transmission structure 122, and a locking element 123. There are two housings 121, which are interlocked. The transmission structure 122 and the locking element 123 are located within the housings 121. The transmission structure 122 is movable in a forward-backward direction. The locking element 123 and the button assembly 20 are respectively connected to both ends of the transmission structure 122.

[0034] Specifically, please refer to the following: Figure 3 and Figure 4The transmission structure 122 includes a linkage rod 1221, a transmission locking rod 1222, and an elastic element 1223. The linkage rod 1221 can move back and forth horizontally within the housing 121. The button assembly 20 is connected to the front end of the linkage rod 1221, and the transmission locking rod 1222 and the elastic element 1223 are connected to the rear end of the linkage rod 1221. The front and rear ends of the elastic element 1223 are respectively connected to the upper parts of the linkage rod 1221 and the locking element 123. In this embodiment, the elastic element 1223 is a tension spring. When the linkage rod 1221 moves horizontally within the housing 121, the transmission locking rod 1222 and the elastic element 1223 move simultaneously under the drive of the linkage rod 1221, and the elastic element 1223 is compressed or stretched.

[0035] The locking member 123 is rotatable to switch between a locked and unlocked state. Limiting bosses 1231 and locking grooves 1232 are provided at both ends of the locking member 123. The limiting bosses 1231 have an arcuate surface. The locking grooves 1232 are used to engage with the fixing rod 50 on the vehicle seat to lock the ISOFIX assembly 10.

[0036] like Figure 3 As shown, in the locked state, the transmission locking rod 1222 abuts against the lower part of the limiting boss 1231, restricting the rotation of the locking member 123. The locking groove 1232 opens downwards, and the fixing rod 50 is located within the locking groove 1232. Figure 4 As shown, in the unlocked state, the transmission locking rod 1222 abuts against the arc surface of the limiting boss 41, the locking groove 1232 opens backward, and the fixing rod 50 disengages from the locking groove 1232, thereby unlocking the safety seat mounting device from the vehicle seat.

[0037] like Figure 1 and Figure 5 As shown, the button assembly 20 is fixed to the outside of the ISOFIX assembly 10, and includes a button base 21 and an unlock button 22. The button base 21 is fixed to the ISOFIX assembly 10. The unlock button 22 is movably disposed within the button base 21 and is used to trigger the wireless communication module 30 to transmit wireless signals outward in the locked state.

[0038] Please refer to the following at the same time Figure 3 and Figure 5 The outer casing 121 has a fixing hole 1211 and a sliding hole 1212 on the side near the button assembly 20. The button assembly 20 is provided with a fixing shaft 211 fixed to the button base 21 and a sliding shaft 221 fixed to the unlock button 22. The fixing shaft 211 is fixed to the fixing hole 1211. The sliding shaft 221 passes through the sliding hole 1212 and is fixed to the transmission structure 122, and the sliding shaft 221 can slide back and forth within the sliding hole 1212. Specifically, the fixing shaft 211 is fixed to the fixing hole 1211 by bolts, and the sliding shaft 221 is fixed to the end of the linkage rod 1221 away from the locking member 123 by bolts.

[0039] Thus, when the button assembly 20 is pressed or released, the unlock button 22 will move relative to the button base 21, and the sliding shaft 221 will move within the sliding hole 1212 under the action of the unlock button 22, thereby driving the linkage rod 1221 to move.

[0040] The wireless communication module 30 can be integrated with the button assembly 20. Alternatively, the wireless communication module 30 can be separately integrated with the button assembly 20 and then fixed together.

[0041] Please refer to the following at the same time Figure 6 The wireless communication module 30 is fixed to the upper side of the button assembly 20 and includes an upper shell 31, a lower shell 32, and a circuit board 33. The upper shell 31 and the lower shell 32 form an accommodating space, and the circuit board 33 is housed within the accommodating space. The circuit board 33 is used to transmit wireless signals outward in the locked state.

[0042] The wireless communication module 30 also includes a fixing part 301 and a triggering part 302. The fixing part 301 is fixed to the button base 21. One of the fixing part 301 and the button base 21 is provided with a protruding fixing rib 212, and the other of the fixing part 301 and the button base 21 is provided with a fixing groove 3011 corresponding to the shape of the fixing rib 212, and the fixing rib 212 is engaged in the fixing groove 3011.

[0043] In this embodiment, as Figure 5 As shown, a fixing groove 3011 is provided on the fixing part 301, and a fixing rib 212 is provided on the button base 21. The fixing groove 3011 is a dovetail groove, which effectively prevents the wireless communication module 30 from detaching from the button assembly 20, so as to make the connection between the wireless communication module 30 and the button assembly 20 more stable and reliable.

[0044] like Figure 6 As shown, a spring-loaded trigger element 34 is provided on the trigger unit 302, and a power switch 331 is provided on the side of the circuit board 33 near the spring-loaded trigger element 34. When the spring-loaded trigger element 34 contacts the power switch 331, the power switch 331 can be turned on, allowing the circuit board 33 to conduct and transmit wireless signals. When the spring-loaded trigger element 34 is separated from the power switch 331, the power switch 331 is turned off, the circuit board 33 is not conducting, and no signal is transmitted.

[0045] like Figure 7 As shown, in the unlocked state, the unlock button 22 is relatively close to the button base 21, and the unlock button 22 is not in direct contact with the elastic trigger 34. The elastic trigger 34 does not receive a trigger from the button assembly 20, extends from the lower housing 32 to the side away from the circuit board 33, and away from the power switch 331.

[0046] When switching from the unlocked state to the locked state, the unlock button 22 moves from the side away from the elastic trigger 34 to the side closer to the elastic trigger 34. For example... Figure 8 As shown, in the locked state, the unlock button 22 abuts against the elastic trigger 34. Under the pressure of the unlock button 22, the elastic trigger 34 moves towards the side closer to the circuit board 33 and contacts the power switch 331, turning on the power switch 331. The circuit board 33 becomes conductive and begins wireless signal transmission.

[0047] Furthermore, the wireless communication module 30 is also equipped with an indicator light 35. The indicator light 35 is connected to the circuit board 33 and is used to display the installation status of the child safety seat installation device. In the locked state, the power switch 331 is turned on, and the indicator light 35 is powered on, indicating that the installation is complete. In the unlocked state, the power switch 331 is turned off, and the indicator light 35 is turned off.

[0048] like Figure 3 and Figure 8 As shown, during the installation of the child safety seat, the ISOFIX assembly 10 moves backward towards the fixing rod 50 on the vehicle seat. The fixing rod 50 contacts the locking member 123 and pushes the locking member 123 to rotate clockwise. After the locking member 123 rotates a certain angle, the fixing rod 50 is located in the locking groove 1232, and the transmission locking rod 1222 abuts against the lower part of the limiting boss 1231, restricting the rotation of the locking member 123, thereby locking the ISOFIX assembly 10 and realizing the transition from the unlocking state to the locking state. At this time, the elastic member 1223 moves backward under the action of the locking member 123, and drives the linkage rod 1221 to move backward together. The linkage rod 1221 drives the unlock button 22 to move backward through the sliding shaft 221. The unlock button 22 moves backward and abuts against the elastic trigger member 34, triggering the wireless communication module 30 to start wireless communication and wirelessly transmit the installation status of the child safety seat installation device.

[0049] like Figure 4 and Figure 7 As shown, when it is necessary to unlock the ISOFIX component 10, pressing the button assembly 20 moves the unlock button 22 forward. The unlock button 22 drives the linkage rod 1221 forward via the sliding shaft 221. The linkage rod 1221 further drives the elastic element 1223 and the transmission locking rod 1222 forward. The transmission locking rod 1222 releases the restriction on the locking element 123, and the elastic element 1223 pulls the locking element 123 counterclockwise. The fixed rod 50 disengages from the locking groove 1232, completing the unlocking of the ISOFIX component 10 and realizing the transition from the locked state to the unlocked state. At the same time, the unlock button 22 leaves the elastic trigger 34, the wireless communication module 30 is powered off, and wireless communication is turned off.

[0050] like Figure 9As shown, this application also provides a safety seat, including a base 40 and a pair of safety seat mounting devices as described above, the pair of safety seat mounting devices being respectively mounted on both sides of the base 40.

[0051] The child safety seat installation device and child safety seat of this application, by setting a wireless communication module 30 fixed to the button assembly 20, can transmit the installation status of the child safety seat installation device wirelessly, reducing wiring workload and simplifying the installation process. Moving the unlock button 22 triggers the wireless communication module 30 to transmit signals in the locked state, requiring no additional operation, simplifying the triggering conditions for wireless signal transmission, and further improving ease of operation.

[0052] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
