[0042] The embodiments of the present invention are now described with reference to the accompanying drawings, in which similar element numbers represent similar elements. The buckle alarm device 100 provided by the present invention is mainly applicable to various infant carriers, but is not limited thereto and can also be used for any other tools.

[0043] Let's combine Figure 1-8As shown, the buckling alarm device 100 of the present invention includes a matching male buckle 110, a female buckle 120 and a wireless connection device 130 arranged therebetween. When the male buckle 110 and the female buckle 120 are buckled or released, the wireless connection device 130 can be turned on or off. When the wireless connection device 130 is turned on, it can send out an identification signal, so that the wireless connection device 130 can be wirelessly connected to a mobile terminal or other device. Thus, the mobile terminal can be used to monitor the buckling state of the buckling alarm device 100. For example, the mobile terminal sends out a corresponding warning signal according to the wireless connection state between the two. The user can infer the buckling state of the buckling alarm device 100 according to the warning signal, and then indirectly obtain the connection, use and other states of the infant carrier, thereby ensuring the riding safety and comfort of the infant.

[0044] See below first Figure 1-6 As shown, in the present invention, the wireless connection device 130 includes a wireless connection module 131 and a control switch 132, both of which are integrated on a circuit board 134, and the control switch 132 is electrically connected to the power supply circuit of the wireless connection module 131, and the circuit board 134 is built into the male buckle 110 and / or the female buckle 120. When the male buckle 110 and the female buckle 120 are engaged or released, the control switch 132 can be closed or disconnected, thereby controlling the circuit where the wireless connection module 131 is located to be turned on or off, and the wireless connection module 131 sends an identification signal when it is turned on.

[0045] In one embodiment of the present invention, the control switch 132 is a mechanical switch, and the control switch 132 protrudes from the plug-in path of the male buckle 110 and the female buckle 120. When the male buckle 110 and the female buckle 120 are engaged, the control switch 132 can be acted on to close it. When the male buckle 110 and the female buckle 120 are disengaged, the control switch 132 can be automatically disconnected.

[0046] See below Figure 6-8 As shown, in the present invention, the wireless connection device 130 also includes a power supply 133 for supplying power to the wireless connection module 131. The power supply 133 can be integrated on the circuit board 134, or can be independently arranged in the male buckle 110 or the female buckle 120 and electrically connected to the circuit board 134. In this embodiment, the power supply 133 is a button-type or soft-pack lithium battery, which is installed in the female buckle 120 through a mounting seat and is electrically connected to the circuit board 134. Of course, the power supply 133 can also use other types of batteries.

[0047] Combine the following Figure 1-4 , Figure 7-8As shown, in the present invention, a plug-in slot 121 is provided on the female buckle 120, and the male buckle 110 can be detachably plugged into the plug-in slot 121; and, a locking member 140 and a releasing member 150 connected to each other are provided between the male buckle 110 and the female buckle 120. After the male buckle 110 is plugged into the plug-in slot 121, the two can be locked by the locking member 140, and the wireless connection module 131 can be turned on. When the releasing member 150 is subjected to force, the locking member 140 can be driven to release the lock to separate the male buckle 110 and the female buckle 120, thereby disconnecting the wireless connection module 131.

[0048] In one embodiment of the present invention, the locking member 140 is a rod member provided in the insertion slot 121 of the female buckle 120, and the releasing member 150 is movably installed on the female buckle 120 and connected to the locking member 140. When the male buckle 110 is inserted into the insertion slot 121, it can be engaged with the locking member 140. When the releasing member 150 is pressed, the releasing member 150 can be driven to move and disengage from the male buckle 110, so that the male buckle 110 and the female buckle 120 can be separated.

[0049] See also Figure 3-4 , Figure 7-8 As shown, the male buckle 110 has a connecting end 111 and a plug-in end 112, and a locking groove 113 is recessed on the plug-in end 112. When the male buckle 110 is plugged into the plug-in groove 121, the locking groove 113 engages with the locking member 140. At the same time, the plug-in end 112 squeezes the control switch 132 to close it. The operating release member 150 can drive the locking member 140 to move and disengage from the locking groove 113, so that the male buckle 110 can be pulled out of the plug-in groove 121.

[0050] Combine the following Figure 6-8 As shown, in one embodiment of the present invention, the circuit board 134 is built into the female buckle 120, and the female buckle 120 is provided with a through hole 122 connected to its plug-in slot 121, and the control switch 132 extends into the plug-in slot 121 through the through hole 122. When the male buckle 110 is plugged into the plug-in slot 121, the control switch 132 can be squeezed to close it. When the male buckle 110 is separated from the plug-in slot 121, the control switch 132 is automatically disconnected and re-extends into the plug-in slot 121. It can be understood that the circuit board 134 and the control switch 132 can also be set in the male buckle 110. In this case, as long as the control switch 132 is protruded outside the plug-in end 112 of the male buckle 110, the control switch 132 can be driven to close when the male buckle 110 is plugged into the plug-in slot 121.

[0051] When the connection mode between the male buckle 110 and the female buckle 120 is changed, the control switch 132 can be turned on or off by locking or releasing the locking alarm device 100 as long as the control switch 132 protrudes on the plugging path of the two.

[0052] See below Figure 3-5As shown, in one embodiment of the present invention, a driving rib 114 is provided on the male buckle 110. When the male buckle 110 is plugged into the plug-in slot 121 of the female buckle 120, the driving rib 114 can squeeze the control switch 132 to close it. After the male buckle 110 is detached from the female buckle 120, the control switch 132 is reset and disconnected.

[0053] More preferably, an anti-breaking protection structure is further provided between the male buckle 110 and the female buckle 120, and the anti-breaking protection structure enables the driving rib 114 to move up and down only at the position of pushing the control switch 132, so as to prevent the male buckle 110 from obliquely pushing the control switch 132 and causing the switch to be accidentally disconnected. In this embodiment, the anti-breaking protection structure includes a matching limiting rib and a limiting groove, one of which is provided at the side of the control switch 132, and the other of which is provided at the side of the driving rib 114 and extends in the same direction as the driving rib 114, and the limiting rib can move along the limiting groove.

[0054] More specifically, two spaced-apart limiting ribs 123 are provided on the inner wall of the plug-in slot 121 of the female buckle 120, a groove 124 is formed between the two limiting ribs 123, the control switch 132 is protruded in the groove 124, and the width of the groove 124 is greater than or equal to the width of the driving rib 114; at the same time, limiting grooves 115 are respectively recessed on both sides of the driving rib 114 of the male buckle 110, and the two limiting grooves 115 correspond to the two limiting ribs 123 respectively. In this way, when the male buckle 110 is plugged into the plug-in slot 121 of the female buckle 120, the two limiting slots 115 are respectively clamped on the two limiting ribs 123, and the driving rib 114 moves in the groove 124 formed between the two limiting ribs 123, so that the driving rib 114 can only move along the plug-in direction of the male buckle 110 and the female buckle 120 to close or disconnect the driving control switch 132, which can prevent the male buckle 110 from obliquely pushing the control switch 132 and causing the control switch 132 to be accidentally disconnected. Of course, the setting positions of the limiting ribs 123 and the limiting slots 115 can be interchanged.

[0055] Continue to see below Figure 3-5As shown, the anti-breakage protection structure is not limited to the above-mentioned setting mode. For example, in other embodiments, a groove can be directly provided on the inner wall of the plug-in slot 121. The groove extends along the plug-in direction of the male buckle 110, and the width of the groove is greater than or equal to the width of the driving rib 114. A through hole is provided in the groove, and the control switch 132 extends through the through hole and is located in the groove. At the same time, the male buckle 110 is provided with a driving rib 114 for being opposite to the groove. In this way, when the male buckle 110 is plugged into the plug-in slot 121 of the female buckle 120, the driving rib 114 can move along the groove and squeeze the control switch 132 to close it, which can also prevent the control switch 132 from being misoperated. It can be understood that when the control switch 132 is provided on the male buckle 110, the groove and the through hole can be provided on the male buckle 110 accordingly, and the driving rib 114 can be provided on the inner wall of the plug-in slot 121 of the female buckle 120, and the driving rib 114 can also be used to drive the control switch 132 to close.

[0056] Combine again below Figure 1-4 As shown, the connecting end 111 of the male buckle 110 is also provided with a hole 116 for the webbing to pass through. Correspondingly, the end of the female buckle 120 away from the plug-in end 112 is also provided with a hole 124 for the webbing to pass through. The connection between the two webbings and other objects connected to the webbings is achieved by the buckling of the male buckle 110 and the female buckle 120.

[0057] See below Figure 7-8 As shown, the snap-fit ​​alarm device 100 of the present invention also includes a pop-up assembly 160, which includes a push piece 161 and an elastic piece 162. The push piece 161 is movably installed in the female buckle 120 and protrudes into the plug-in slot 121, and the push piece 161 can move along the plug-in direction of the male buckle 110. The elastic piece 162 abuts between the push piece 161 and the female buckle 120, and the elastic piece 162 always has a tendency to move the push piece 161 toward the opening of the plug-in slot 121. When the male buckle 110 is inserted into the insertion slot 121, the male buckle 110 pushes the pushing member 161 to move and compress the elastic member 162. When the male buckle 110 and the female buckle 120 are released, the elastic member 162 recovers its deformation and pushes the pushing member 161 to return to its original position, so that the pushing member 161 pushes the male buckle 110 to automatically disengage from the female buckle 120, so that the unlocking operation of the buckle alarm device 100 can be performed with one hand, which is more convenient to operate.

[0058] Combine again Figure 1-8As shown, the snap-fit ​​alarm device 100 of the present invention is not limited to controlling the on and off of the wireless connection module 131 by a mechanical switch. For example, in other embodiments, a relay switch and a sensor can be used to control the on and off of the wireless connection module 131. The sensor is arranged between the male buckle 110 and the female buckle 120 to detect the connection status between the two. For example, the sensor is arranged in the female buckle and electrically connected to the circuit board. When the male buckle 110 and the female buckle 120 are snapped together, the sensor detects the male buckle 110 and generates a sensing signal. When the male buckle 110 and the female buckle 120 are disengaged, the sensor has no sensing signal. The wireless connection device 130 controls the on and off of the relay switch according to the sensing signal to realize the on or off of the wireless connection module 131.

[0059] See below Fig. 9 As shown, the present invention also provides a snap-fit ​​alarm system, which includes a snap-fit ​​alarm device 100 and a mobile terminal 200. The structure of the snap-fit ​​alarm device 100 is as described above and will not be described again. The mobile terminal 200 can recognize the identification signal emitted by the wireless connection module 131 and establish a wireless connection therewith. At the same time, the mobile terminal 200 can emit a warning signal according to whether it is connected to the wireless connection module 131, to prompt the user of the connection, use and other status of the snap-fit ​​alarm device 100.

[0060] In a preferred embodiment, the mobile terminal 200 is preset to be able to recognize the identification signal sent by the wireless connection module 131 within a certain distance and automatically establish a wireless connection with it. The distance range can be preset by the factory settings of the mobile terminal 200, or it can be set to a mode that is automatically adjusted by the user as needed. For example, it is preset that the two can recognize the corresponding signal and automatically connect within a range of 5m. In this way, after the mobile terminal 200 and the buckle alarm device 100 are connected, if the mobile terminal 200 does not receive the identification signal sent by the wireless connection module 131 and disconnects from it, the mobile terminal 200 will send a warning signal. The user can infer the buckle, use, etc. of the buckle alarm device 100 based on the approximate distance between the mobile terminal 200 and the buckle alarm device 100. For example, if the warning signal is received within the preset distance, it is inferred that the male buckle 110 and the female buckle 120 may not be fastened properly. If the warning signal is received beyond the preset distance, it can be prompted that the user is far away from the infant carrier to prevent the infant from being forgotten in the infant carrier or prevent the infant carrier from being out of the adult's sight.

[0061] Furthermore, the frequency at which the wireless connection module 131 sends the identification signal in different time periods can also be preset. For example, the wireless connection module 131 is preset to send the identification signal at a first frequency within a first time period after being turned on, and thereafter, the identification signal is sent at a second frequency, wherein the first frequency is higher than the second frequency, thereby achieving the purpose of power saving. In a specific embodiment of the present invention, the wireless connection module 131 is preset to send an identification signal every 2 seconds within 10 minutes after being turned on, and after 10 minutes, the identification signal is sent every 2 minutes. Of course, it is not limited to the frequency in this embodiment.

[0062] Combine again Figure 1-9 As shown, the wireless connection module 131 in the present invention is preferably a Bluetooth module, but it is not limited thereto, and a wireless connection method can also be used, such as using a radio frequency identification (RFID) module to achieve wireless connection. In addition, the mobile terminal 200 involved in the present invention can be a mobile phone, iPad, smart watch, smart bracelet, etc., but is not limited to the aforementioned devices, and can also be other mobile devices. In one embodiment, a wireless connection is established through a built-in Bluetooth module in the mobile phone and a Bluetooth module in the buckle alarm device, so that the setting and connection of the buckle alarm device 100 are simpler.

[0063] Preferably, the warning signal sent by the mobile terminal 200 may be at least one of a vibration alarm, a sound alarm, a flashing screen alarm, a pattern alarm, and a text message alarm, but is not limited thereto.

[0064] See below Fig.10 As shown, the present invention also provides a buckle alarm method using the buckle alarm device as described above, the method comprising the following steps:

[0065] Step S01: Determine whether the identification signal sent by the wireless connection module is received; if so, proceed to step S02, otherwise, return to step S01;

[0066] Step S02: automatically establishing a connection with the wireless connection module;

[0067] Step S03: Detect and determine whether the wireless connection module is in a connection state; if not, proceed to step S04, otherwise, return to step S03;

[0068] Step S04: issuing a warning signal; wherein the warning signal may be at least one of a vibration alarm, a sound alarm, a flashing screen alarm, a pattern alarm, and a text message alarm, but is not limited thereto.

[0069] Preferably, before step S01, it also includes: presetting the frequency at which the wireless connection module sends the identification signal in different time periods; in a specific implementation, the wireless connection module is preset to send the identification signal at a preset first frequency within a first time period after being turned on, and thereafter, to send the identification signal at a preset second frequency, wherein the first frequency is higher than the second frequency. For example, the wireless connection module 131 is preset to send an identification signal every 2 seconds within 10 minutes after being turned on, and after 10 minutes, to send an identification signal every 2 minutes, thereby achieving the purpose of power saving.

[0070] Next, combine Figure 1-9 As shown, taking the buckle alarm device 100 used on a car safety seat and a mobile phone as an example, its use and principle are explained.

[0071] When the infant is seated on the car safety seat, the male buckle 110 and the female buckle 120 of the buckle alarm device 100 are buckled together to install the safety seat or restrain the infant. Figure 7 The male buckle 110 is inserted into the insertion slot 121 of the female buckle 120 in the direction indicated by the middle arrow F1. During the movement of the male buckle 110, the control switch 132 will be squeezed to close it, so that the wireless connection module 131 is turned on and sends out an identification signal. The built-in Bluetooth module of the mobile phone can identify the identification signal sent by the wireless connection module 131 and automatically connect with it. Afterwards, during the use of the car safety seat, if the mobile phone does not receive the identification signal sent by the wireless connection module 131 and disconnects from it, the mobile phone will send out a warning signal according to a preset method. At this time, if the driver and the passenger are in the car, it can be inferred that the male buckle 110 and the female buckle 120 of the buckle alarm device 100 may be loose. If the driver and the passenger leave the car, it may be due to the long distance between the mobile phone and the wireless connection device 130, resulting in the mobile phone being unable to receive the identification signal sent by the wireless connection module 131 and disconnecting from it, thereby indirectly reminding the driver and the passenger that there are infants and young children in the car, so as to prevent the infants and young children from being forgotten in the car or prevent the infants and young children from being out of sight of adults for a long time, thereby ensuring the safety of the infants and young children in the car.

[0072] When the male buckle 110 and the female buckle 120 of the buckled alarm device 100 are unlocked, the elastic member 162 recovers its deformation and pushes the pushing member 161 to reset, so that the pushing member 161 pushes the male buckle 110 to automatically disengage from the female buckle 120, thereby resetting the control switch 132 and automatically disconnecting it, so that the wireless connection module 131 is disconnected and stops sending the identification signal.

[0073] In summary, since the buckling alarm device 100 of the present invention has a wireless connection module 131 set between the male buckle 110 and the female buckle 120, when the male buckle 110 and the female buckle 120 are buckled or released, the wireless connection module 131 can be turned on or off, and the wireless connection module 131 sends out an identification signal when it is turned on. Therefore, the wireless connection module 131 can be cooperated with the mobile terminal 200 to realize wireless connection. The mobile terminal 200 sends out a warning signal according to whether it is connected to the wireless connection module 131, thereby prompting the user of the connection status of the buckling alarm device 100, so that the user can further infer the use status of the infant carrier according to the connection status of the buckling alarm device 100, thereby ensuring the safety of the infant carrier during use and the comfort of the infant riding.

[0074] Correspondingly, the buckle alarm system having the buckle alarm device 100 of the present invention and the buckle alarm method using the buckle alarm device have the same technical effects.

[0075] The car safety seat, mobile terminal 200 and the like involved in the present invention are conventional devices well known to those skilled in the art, and will not be described in detail herein.

[0076] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
