[0058] The present invention will now be described with reference to the accompanying drawings, wherein like reference numerals represent like elements. The child safety seat safety warning system 100 provided by the present invention is primarily applicable to a child safety seat 200, but is not limited thereto and may also be used in other infant carriers.

[0059] See below first Figure 1-Figure 4 As shown, the child safety seat 200 of the present invention mainly includes a base 210 and a seat body 220 mounted on the base 210. In addition, the seat body 220 is provided with a top strap 230, and the rear end of the base 210 is provided with two ISOFIX connectors 240. The top strap 230 and the two ISOFIX connectors 240 are used to connect to the car to fix the child safety seat 200, thereby forming a three-point connection to meet safety standards. Figure 1 The seat body 220 is also provided with a safety belt system for restraining infants and young children. Figure 1 The safety belt system is not fully shown, but the setting of the safety belt system is conventional in the field. A buckle 250 is provided on the safety belt system, and the buckle 250 is fastened to fix the safety belt system to the infant sitting on the seat body 220.

[0060] The following combination Figure 1-Figure 25 As shown, the child safety seat safety warning system 100 of the present invention includes a first detection device 110, a second detection device 120, a third detection device 130, a relay control device 140, and an alarm device 150. The first detection device 110 is located along the movement path of the top tether 230 and is used to detect the tension of the top tether 230 and to issue a first detection signal when the top tether 230 is tightened. The second detection device 120 is located on the ISOFIX connector 240 and is used to detect whether the ISOFIX connector 240 is properly installed and to issue a second detection signal when the ISOFIX connector 240 is properly installed. The third detection device 130 is located on the buckle 250 and is used to detect whether the buckle 250 is engaged and to issue a third detection signal when the buckle 250 is engaged. The transfer control device 140 is electrically connected to the first detection device 110, the second detection device 120, the third detection device 130, and the alarm device 150, respectively, and is used to receive the first detection signal, the second detection signal, and the third detection signal, and to issue an alarm signal when at least one of the first detection signal, the second detection signal, and the third detection signal is not received; the alarm device 150 is used to receive the aforementioned alarm signal and to alarm according to the alarm signal.

[0061] It should be noted that the number of the first detection device 110, the second detection device 120, and the third detection device 130 can be flexibly set according to needs. For example, at least one first detection device 110 can be set according to the setting method of the top strap 230. For the ISOFIX connector 240, the preferred method is to set the second detection device 120 in each ISOFIX connector 240, but it is not limited to this. The third detection device 130 is specifically selected according to the number of fasteners 250.

[0062] Continue to read Figure 1-2 As shown, in the present invention, the relay control device 140 is preferably installed in the base 210, but is not limited thereto and can be installed in any convenient location on the child safety seat 200. In addition, the relay control device 140 can also be installed in a car (details will be described later).

[0063] Continue to combine Figure 1-2 、 Figure 14 、 Figure 25 As shown, the transfer control device 140 can also be connected to the mobile terminal 300 or the vehicle control system (not shown) to communicate and send an alarm signal to the mobile terminal 300 or the vehicle control system, and then display the alarm information through the mobile terminal 300 or the vehicle control system, thereby more conveniently prompting the user.

[0064] See Figure 14 、 Figure 25As shown, the transfer control device 140 includes a signal processing module 141 and a wireless communication module 142. The transfer control device 140 is connected to the mobile terminal 300 or the vehicle control system through the wireless communication module 142. The signal processing module 141 is used to obtain the first detection signal, the second detection signal, and the third detection signal and process the signals. When it does not receive at least one of the first detection signal, the second detection signal, and the third detection signal, it generates an alarm signal. In this case, the signal processing module 141 can directly control the alarm device 150 to alarm based on the alarm signal, or it can send the alarm signal to the mobile terminal 300 or the vehicle control system through the wireless communication module 142. After receiving the alarm signal, the mobile terminal 300 can notify the user through information, voice, vibration, etc., and the vehicle control system can notify the user through a display screen or voice prompt based on the alarm signal. Of course, the notification methods of the mobile terminal 300 or the vehicle control system are not limited to the above methods.

[0065] Preferably, the wireless communication module 142 may be a Bluetooth module, a Wi-Fi module, or a radio frequency identification (RFID) module, etc., and is certainly not limited to the aforementioned wireless connection modules, and other wireless connection methods may also be used to achieve wireless connection. In addition, the mobile terminal 300 involved in the present invention includes but is not limited to a user's mobile phone, a tablet computer, a smart watch, a smart bracelet, and may also be other removable devices.

[0066] Continue to combine Figure 1-2 、 Figure 13-14 、 Figure 24 As shown, in the present invention, the alarm device 150 and the relay control device 140 are preferably provided independently, and the alarm device 150 is mounted on the front end of the base 210 and exposed on the upper surface of the base 210 for easy viewing by the user. Of course, the alarm device 150 can also be mounted at any other convenient location on the child safety seat 200. In addition, the alarm device 150 and the relay control device 140 can be electrically connected via wired or wireless means.

[0067] In the present invention, the alarm device 150 may be at least one of an audible alarm, a luminous alarm, a vibrating alarm, and a display alarm, but is not limited to the aforementioned alarm methods. When the relay control device 140 fails to receive at least one of the first detection signal, the second detection signal, and the third detection signal and issues an alarm signal, the alarm device 150 issues an alarm based on the received alarm signal. The alarm method may be at least one of an audible alarm, a light alarm, a vibration alarm, a graphic alarm, and a text message alarm to alert the user that at least one of the top tether 230, the ISOFIX connector 240, and the buckle 250 is not properly installed.

[0068] In a preferred embodiment, the alarm device 150 includes a first alarm 151 and a second alarm 152, wherein the first alarm 151 is a sound alarm and has one, and the first alarm 151 is used to emit an alarm prompt sound, and the second alarm 152 is a light alarm and has multiple, and the second alarm 152 is used to indicate the installation status of the top strap 230, the ISOFIX connector 240, and the buckle 250 respectively.

[0069] More specifically, first alarm 151 is preferably a buzzer, and second alarm 152 is preferably three LEDs. The three second alarms 152 correspond to the first detection signal, the second detection signal, and the third detection signal, respectively, and are used to indicate the connection status of the top tether 230, the ISOFIX connector 240, and the buckle 250. That is, if the transfer control device 140 does not receive at least one of the first detection signal, the second detection signal, or the third detection signal and generates and issues an alarm signal, the alarm device 150 triggers the buzzer to sound an alarm to alert the user based on the received alarm signal, and simultaneously triggers the corresponding LED to light up or flash, clearly notifying the user which specific component is not properly installed, allowing the user to quickly check and reinstall it.

[0070] It is understood that the number of second alarms 152 can be flexibly selected as needed. For example, when more components need to be inspected, the number of second alarms 152 can be set accordingly. Alternatively, when multiple parts of the same component need to be inspected, the number of second alarms 152 can be set accordingly to achieve the purpose of accurate indication. In addition, only one alarm light can also serve as a warning.

[0071] It is understandable that the alarm device 150 and the relay control device 140 can of course be integrated into one. In this case, after the relay control device 140 is installed, it is sufficient to expose the first alarm 151 and the second alarm 152 on the surface of the child safety seat 200 for the user to observe.

[0072] Combine again below Figure 1-Figure 25As shown, in the present invention, the transfer control device 140 can be integrated with the first detection device 110, the second detection device 120, the third detection device 130, and the alarm device 150. In this case, it is only necessary to set the detection components of the first detection device 110, the second detection device 120, and the third detection device 130 corresponding to the components to be detected (see below for details), and the alarm device 150 is set as described above. Of course, the transfer control device 140 and the first detection device 110, the second detection device 120, the third detection device 130, and the alarm device 150 can be set independently. When each device is set independently, the transfer control device 140 and the first detection device 110, the second detection device 120, and the third detection device 130 are electrically connected by wire or wireless means (see below for details), and the alarm device 150 is set as described above; and in this setting, the transfer control device 140 can be set in the child safety seat 200 or in the car. Different implementations of the child safety seat safety warning system 100 of the present invention are described below.

[0073] Combine first Figures 1-14 As shown, in the first embodiment of the child safety seat safety warning system 100 of the present invention, the relay control device 140 is integrated with the first detection device 110, the second detection device 120, and the third detection device 130, specifically integrated on the same circuit board, and the relay control device 140 is installed in the base 210, as shown in FIG. Figure 2 Furthermore, the transfer control device 140 and the alarm device 150 are separately provided and electrically connected to each other via wires. The arrangement of the alarm device 150 is as described above and will not be described again.

[0074] Combine Figure 3-8 、 Figure 13-14 As shown, in this embodiment, a first detection device 110 is provided, and the first detection device 110 includes a first detection member 111. The first detection member 111 is provided on the moving path of the top strap 230 and is used to detect the tensioning state of the top strap 230. The first detection member 111 is electrically connected to the circuit board of the transfer control device 140 through an electric wire. When the top strap 230 is tightened, it acts on the first detection member 111 to generate an induction signal, thereby causing the first detection device 110 to generate a first detection signal, and the transfer control device 140 can obtain the first detection signal.

[0075] In this embodiment, the first detection member 111 is preferably a mechanical switch, which includes but is not limited to a button switch and a spring switch. Figure 4-5When the button switch is shown, the first detection member 111 has a button 1111, which is installed on the back of the base 210 or the seat body 220 and makes the button 1111 protrude on the moving path of the top strap 230. Figure 7-8 When the spring switch is used as shown, the first detection member 111 has a spring 1112, which is installed on the back of the base 210 or the seat body 220 so that the spring 1112 protrudes on the moving path of the top strap 230. Figure 4-5 、 Figure 7-8 When the top strap 230 is tightened in the direction indicated by the middle arrow F1, the top strap 230 will apply a force to the button 1111 or the spring 1113 of the first detection member 111 to close it, so that the detection circuit of the first detection device 110 is turned on and a first detection signal is generated. When the top strap 230 is loosened, the first detection member 111 (mechanical switch) loses its force and automatically disconnects. At this time, the first detection device 110 cannot generate a first detection signal.

[0076] It is understood that the first detection member 111 is not limited to a mechanical switch and can also be used in other detection methods, such as a contact sensor, a pressure sensor, an infrared sensor, or a displacement sensor, but is not limited to the detection devices listed here. Taking the pressure sensor as an example, when it detects that the pressure exerted by the top strap 230 on it reaches a preset value, it generates a sensing signal, and the first detection device 110 generates a first detection signal based on the sensing signal.

[0077] Continue to combine Figure 3-5 As shown, in a specific implementation of this embodiment, the first detection member 111 is arranged on the back of the seat body 220 and corresponds to the top tether 230. More specifically, the rear end of the base 210 is also provided with a support rod 260. The support rod 260 has a hollow structure. The top of the support rod 260 is provided with a fixing block 270. The fixing block 270 is provided with a fixing rod 271. The lower end of the top tether 230 is connected to the fixing rod 271, and the upper end is provided with a hook for connecting to the top of the car (not shown). The first detection member 111 can be installed on any of the top of the support rod 260, the fixing block 270, and the back of the seat body 220. The preferred method is to install it on the fixing block 270 and correspond to the side of the top tether 230 so that it can act on the first detection member 111 during the tightening process of the top tether 230. At the same time, the wires electrically connected to the first detection member 111 are routed through the interior of the support rod 260. Therefore, the support rod 260 not only serves to install the top strap 230 , but also facilitates the routing of the wires of the first detection device 110 , making the external structure of the child safety seat 200 simple and beautiful.

[0078] The following combination Figure 6-8As shown, in another specific implementation of this embodiment, the first detection member 111 is installed at the rear end of the base 210, the lower end of the top strap 230 can be directly connected to the base 210, and the first detection member 111 can be located on the moving path of the top strap 230. Similarly, the top strap 230 can act on the first detection member 111 to enable the first detection device 110 to generate a first detection signal.

[0079] However, in the present specific embodiment, in order to ensure accurate action on the first detection member 111 to ensure the accuracy of detection, the first detection device 110 is further provided with a first trigger member 112 and an elastic member 113. The first trigger member 112 is movably arranged on the base 210, and the first trigger member 112 is connected to the top strap 230. The elastic member 113 abuts against the first trigger member 112. During the tightening process of the top strap 230, the first trigger member 112 is driven to move, so that the first trigger member 112 acts on the button 1111 or the spring 1112 of the first detection member 111, so that the first detection member 111 is closed, and thus the first detection device 110 generates a first detection signal; when the top strap 230 is not tightened, the elastic force of the elastic member 113 causes the first trigger member 112 to reset to release the button 1111 or the spring 1112 of the first detection member 111, thereby disconnecting the first detection member 111.

[0080] Continue to read Figure 7-8 As shown, in this specific embodiment, the first detection device 110 further includes a traction member 114, which is accommodated in the support rod 260 and has two ends connected to the first trigger member 112 and the top lace 230 respectively. The lower end of the top lace 230 is slidably connected to the top of the support rod 260. When the top lace 230 is tightened upward by an external force, the first trigger member 112 is pulled along the traction member 114. Figure 7-8 The first triggering member 112 moves upward in the direction indicated by the middle arrow F1 . During the movement, the first triggering member 112 acts on the spring piece 1112 of the first detecting member 111 , so that the first detecting member 111 is closed.

[0081] It should be noted that, in the above two specific embodiments, the support rod 260 can be as follows: Figure 3 As shown, it is made up of multiple rods, or it can be made up of Figure 6 It is shown that the support rod 260 is composed of only one rod, which does not affect the installation of the first detection member 111 and the top strap 230 in this embodiment, so the specific structure of the support rod 260 is not limited here.

[0082] The following combination Figure 9 、 Figure 13-14As shown, in this embodiment, two second detection devices 120 are provided. The two second detection devices 120 are respectively provided on the ISOFIX connectors 240 to detect the installation status of the two ISOFIX connectors 240. The structures and settings of the two second detection devices 120 are the same.

[0083] like Figure 9 As shown, the second detection device 120 includes a second detection member 121, which is installed on the ISOFIX connector 240 to detect its installation status, and the second detection member 121 is electrically connected to the circuit board of the relay control device 140 through an electric wire. When the ISOFIX connector 240 is installed in place, it will act on the second detection member 121 to generate an induction signal, thereby causing the second detection device 120 to generate a second detection signal, and the relay control device 140 can obtain the second detection signal.

[0084] In this embodiment, the second detection member 121 is preferably a mechanical switch, and the second detection member 121 is preferably a spring switch. The second detection member 121 has a spring 1211 that protrudes from the movement path of the ISOFIX connector 240. Of course, the second detection member 121 can also be a push button switch or other type of mechanical switch. The second detection member 121 is electrically connected to the circuit board of the transfer control device 140 via wires. When the ISOFIX connector 240 is installed in place, the spring 1211 of the second detection member 121 acts on it to close it, thereby turning on the detection circuit of the second detection device 120 and generating a second detection signal.

[0085] Similarly, the second detection member 121 is not limited to a mechanical switch. For example, it can also be any one of a contact sensor, a pressure sensor, an infrared sensor, and a displacement sensor, but is not limited to these detection devices. Taking the contact sensor as an example, it is installed on the ISOFIX connector 240. When the ISOFIX connector 240 is in place, it can act on the contact sensor to generate a sensing signal. The second detection device 120 generates a second detection signal based on the sensing signal.

[0086] Continue to read Figure 9As shown, in this embodiment, the second detection device 120 further includes a second trigger member 122, which is movably arranged and connected to the ISOFIX connector 240. During the installation process of the ISOFIX connector 240, the second trigger member 122 is driven to move to act on the spring piece 1211 of the second detection member 121, so that the second detection member 121 (mechanical switch) is closed. After the ISOFIX connector 240 is installed in place, the second trigger member 122 will always keep the second detection member 121 in the closed position, thereby making the detection circuit of the second detection device 120 conductive and generating a second detection signal. When the ISOFIX connector 240 is released and disengaged from the locking member on the car, the second detection member 121 (mechanical switch) loses its force and automatically disconnects. At this time, the second detection device 120 cannot generate the first detection signal.

[0087] The following combination Figure 10-13 As shown, the third detection device 130 includes a third detection member 131, which is arranged on the fastening path of the fastener 250 and is electrically connected to the circuit board of the transfer control device 140 through wires. When the fastener 250 is fastened, it acts on the third detection member 131 to generate an induction signal, thereby causing the third detection device 130 to generate a third detection signal, and the transfer control device 140 can obtain the third detection signal.

[0088] Continue to read Figure 10-12 As shown, in this embodiment, the third detection member 131 is preferably a mechanical switch, which is built into the male buckle 251 or the female buckle 252 and protrudes from the plug-in path of the two. When the male buckle 251 and the female buckle 252 are engaged, the mechanical switch can be acted on to close it. When the male buckle 251 and the female buckle 252 are disengaged, the mechanical switch can be automatically disconnected.

[0089] In this embodiment, the third detection member 131 is built into the female buckle 252. When the male buckle 251 is inserted into the female buckle 252, it can act on the third detection member 131 to close it. More specifically, the female buckle 252 is provided with an insertion groove 2521, and the female buckle 252 is provided with a through hole 2522 connected to the insertion groove 2521. The third detection member 131 is built into the female buckle 252, and its button 1311 protrudes into the insertion groove 2521 through the through hole 2522. Figure 12-13 In addition, a locking rod 2523 is provided within the insertion slot 2521 of the female buckle 252. The locking rod 2523 is movably disposed, and a release member 2524 is provided on the female buckle 252 for driving the locking rod 2523 to move. Thus, when the male buckle 251 is inserted into the insertion slot 2521, it engages with the locking rod 2523. Pressing the release member 2524 drives the locking rod 2523 to move and disengage from the male buckle 251, allowing the male buckle 251 and the female buckle 252 to separate.

[0090] Correspondingly, the male buckle 251 has a plug-in end 2511, and a driving rib 2512 is convexly provided at the rear end of the plug-in end 2511, and a locking groove 2513 is recessed at the front end of the plug-in end 2511. When the male buckle 251 is plugged into the plug-in groove 2521, the locking groove 2513 at its front end engages with the locking rod 2523, and at the same time, the driving rib 2512 at its rear end squeezes the button 1311 of the third detection member 131 to close it, so that the third detection device 130 generates a third detection signal. When the operation release member 2524 drives the locking rod 2523 to move and disengage from the locking groove 2513, the male buckle 251 can be pulled out of the plug-in groove 2511. At this time, the third detection member 131 loses its force and automatically disconnects, thereby preventing the third detection device 130 from generating a third detection signal.

[0091] It is understood that the third detection member 131 is not limited to a mechanical switch and can also be any of a contact sensor, a pressure sensor, an infrared sensor, and a displacement sensor. For example, a contact sensor is built into the male buckle 251 or the female buckle 252. When the male buckle 251 is inserted into the female buckle's insertion slot 2521, it acts on the contact sensor to generate a sensing signal, thereby causing the third detection device 130 to generate and transmit a third detection signal.

[0092] The following combination Figures 15-19 As shown, the second embodiment of the child safety seat safety warning system 100 of the present invention is different from the first embodiment mentioned above mainly in that the number of first detection devices 110 is different, and other parts are the same, and the same parts will not be repeated.

[0093] In this embodiment, the top strap 230 includes a left strap 231 and a right strap 232. The left strap 231 and the right strap 232 are respectively fixed to the base 210 or the seat body 220. The upper ends of the left strap 231 and the right strap 232 are connected and installed with a hook (not shown). When the hook is connected to the top of the car, the left strap 231 and the right strap 232 can be tightened.

[0094] In this embodiment, the first detection device 110 is respectively provided corresponding to the left webbing 231 and the right webbing 232, that is, the tensioning status of the left webbing 231 and the right webbing 232 is respectively detected by the two first detection devices 110. When the top strap 230 is tightened, the two first detection devices 110 respectively send out a first detection signal, thereby monitoring the tensioning status of the left webbing 231 and the right webbing 232.

[0095] The two first detection devices 110 have the same structure, and each first detection device 110 can adopt the setting method of the above-mentioned first embodiment, or can adopt other setting methods. In this embodiment, the first detection device 110 is further provided with a sliding member 115 compared with the method in the above-mentioned first embodiment.

[0096] Continue to combine Figures 15-19 As shown, the first detection device 110 corresponding to the left webbing 231 is used as an example for explanation. The first detection device 110 includes a first detection member 111a, a first trigger member 112, an elastic member 113, a traction member 114 and a sliding member 115. The first trigger member 112 is movably arranged on the side of the base 210, and the first trigger member 112 is connected to the left webbing 231 through the traction member 114, and the elastic member 113 abuts against the first trigger member 112; the first detection member 111a is electrically connected to the circuit board of the transfer control device 140 through an electric wire, and the first detection member 111a is located on the side of the first trigger member 112; the sliding member 115 is slidably installed on the back of the seat body 220, and the sliding member 115 is respectively connected to the left webbing 231 and the traction member 114. Therefore, when the top strap 230 is tightened, the sliding member 115 is pulled along Figure 17 The sliding member 115 moves upward in the direction indicated by the middle arrow F1, and then the first trigger member 112 is pulled along the Figure 17 The first trigger member 112 moves upward in the direction indicated by the middle arrow F1, during which the first trigger member 112 acts on the first detection member 111a to generate a first detection signal. Furthermore, during the upward movement of the first trigger member 112, the first trigger member 112 acts on the elastic member 113, causing it to deform. When the top strap 230 is released, the elastic member 113 recovers its deformation and drives the first trigger member 112 downward, thereby releasing the first detection member 111a and preventing the first detection device 110 from generating the first detection signal.

[0097] It can be understood that the first detection device 110 corresponding to the right webbing 232 is inferred from the above description, wherein the first detection member 111b is electrically connected to the circuit board of the transfer control device 140 through a wire, such as Figure 19 It should be noted that the first detection members installed corresponding to the left webbing 231 and the right webbing 232 are respectively described as 111a and 111b for ease of description only, and the two are the same.

[0098] Continue to read Figure 15-16 As shown, in this embodiment, the support rods 260 provided at the rear end of the base 210 specifically include a left support rod 261, a right support rod 262, and a cross support rod 263 connecting the tops of the two, all of which are hollow structures. The left webbing 231 of the top tether 230 is threaded through the left support rod 261, and the right webbing 232 is threaded through the right support rod 262. The upper ends of the left and right support rods 261 and 262, respectively, are fixedly connected. The traction member 114 is threaded through the left and right support rods 261 and 262, thereby giving the child safety seat 200 a simple and beautiful appearance.

[0099] See Figure 19As shown, in this embodiment, two second detection devices 120 are also provided. The setting method of the two second detection devices 120 is the same as the above embodiment. In this embodiment, the second detection members installed on the two ISOFIX connectors 240 are respectively expressed as 121a and 121b for the convenience of explanation, and the two second detection members 121a and 121b are electrically connected to the circuit board of the transfer control device 140 through wires.

[0100] Recombination Figures 15-19 As shown, in this embodiment, in order to facilitate accurate prompting of the user, the alarm device 150 further adds two second alarms 152 on the basis of the above-mentioned setting method, that is, a total of five second alarms 152 are set, and the five second alarms 152 are used to indicate the connection status of the left webbing 231, the right webbing 232, the two ISOFIX connectors 240 and the buckle 250 respectively. Specifically, when the left webbing 231 and / or the right webbing 232 are not tightened, the first detection member 111a and / or 111b are disconnected, and the relay control device 140 sends an alarm signal to control the second alarm 152 corresponding to the two to alarm; when at least one of the two ISOFIX connectors 240 is not installed in place, the second detection member 121a and / or 121b are disconnected, and the relay control device 140 sends an alarm signal to control the second alarm 152 corresponding to the two to alarm; when the buckle 250 is not fastened, the third detection member 131 is disconnected, and the relay control device 140 sends an alarm signal to control the second alarm 152 corresponding to the buckle 250 to alarm.

[0101] It should be noted that the structure and working method of the alarm device 150 not mentioned here are the same as those described above.

[0102] The following combination Figure 20-24 As shown, the third embodiment of the child safety seat safety warning system 100 of the present invention differs from the first embodiment primarily in that a relay control device 140 is independently provided from the first detection device 110, the second detection device 120, the third detection device 130, and the alarm device 150. Furthermore, the first detection device 110, the second detection device 120, the third detection device 130, and the alarm device 150 are electrically connected to the relay control device 140 via wires. The specific configuration of the alarm device 150 can be any of the above-described configurations and will not be described again.

[0103] In this embodiment, the first detection device 110 further includes a first detection circuit board 110a. A first detection member 111 is disposed along the travel path of the top strap 230 and is electrically connected to the first detection circuit board 110a. The first detection circuit board 110a can be mounted on the fixing block 270, the back of the seat body 220, or the base 210. The first detection circuit board 110a is electrically connected to the relay control device 140 via wires. Therefore, when the top strap 230 is tightened, it acts on the first detection member 111, causing it to generate a sensing signal. The first detection device 110 generates a first detection signal based on the sensing signal from the first detection member 111 and transmits it to the relay control device 140.

[0104] Continue to combine Figure 20-24 As shown, in this embodiment, the second detection device 120 also includes a second detection circuit board 120a, which is arranged on the ISOFIX connector 240 and electrically connected to the transfer control device 140 through wires, and the second detection member 121 is electrically connected to the second detection circuit board 120a. When the ISOFIX connector 240 is installed in place, it acts on the second detection member 121, thereby generating an induction signal, and the second detection device 120 generates a second detection signal based on the induction signal.

[0105] Correspondingly, the third detection device 130 also includes a third detection circuit board 130a, which is built into the female buckle 252 and electrically connected to the transfer control device 140 through wires. The third detection member 131 is electrically connected to the third detection circuit board 130a and built into the female buckle 252. The button 1311 of the third detection member 131 protrudes through the through hole 2522 on the fastening path of the buckle 250, and acts on the third detection member 131 when the buckle 250 is fastened, so that the third detection device 130 generates and sends a third detection signal.

[0106] It is understandable that the third detection circuit board 130 a and the third detection member 131 may also be built into the male buckle 251 .

[0107] See again Figure 23 As shown, in this embodiment, the third detection device 130 further includes a power supply 132. This power supply 132 is a button-type or soft-pack lithium battery. This lithium battery is installed in the female connector 120 and is electrically connected to the third detection circuit board 130a. It is used to power the third detection circuit board 130a and the third detection member 131. Therefore, when the third detection member 131 is closed, the circuit on the third detection circuit board 130a is conductive, causing it to generate a third detection signal. Of course, the power supply 132 can also be other types of batteries, or it can be integrated into the third detection circuit board 130a.

[0108] In this embodiment, the number, installation method, and working principle of the first detection device 110, the second detection device 120, and the third detection device 130 can be any of the forms in the first and second embodiments above, and will not be described again.

[0109] The following combination Figure 20-23 、 Figure 25 As shown, the fourth embodiment of the child safety seat safety warning system 100 of the present invention differs from the third embodiment described above primarily in that a relay control device 140 is wirelessly connected to the first detection device 110, the second detection device 120, and the third detection device 130, respectively. This reduces the wiring between the devices and simplifies the connection of the child safety seat safety warning system 100. Furthermore, because each device is independently configured and wirelessly connected, the relay control device 140 can be installed not only on the child safety seat 200 but also in the vehicle, such as on the vehicle's control panel. This makes the relay control device 140 more flexible to install and facilitates wireless connection with a wider range of devices.

[0110] In this embodiment, the structural settings of the first detection device 110, the second detection device 120, the third detection device 130, and the transfer control device 140 are the same as those in the third embodiment above, so they are not described again. Only the wireless connection part is explained below.

[0111] like Figure 25 As shown, in this embodiment, the first detection device 110 also includes a first wireless module 112 provided on the first detection circuit board 110a. The first wireless module 112 is used to wirelessly connect to the wireless communication module 142 of the relay control device 140. Therefore, the first detection signal of the first detection device 110 is sent to the relay control device 140 through the first wireless module 112.

[0112] Correspondingly, the second detection device 120 further includes a second wireless module 122 provided on the second detection circuit board 120a. The second wireless module 122 is used to wirelessly connect to the wireless communication module 142 of the relay control device 140. The second detection signal of the second detection device 120 is transmitted to the relay control device 140 via the second wireless module 122. The third detection device 130 further includes a third wireless module 132 provided on the third detection circuit board 130a. The third wireless module 132 is used to wirelessly connect to the wireless communication module 142 of the relay control device 140. The third detection signal of the third detection device 130 is transmitted to the relay control device 140 via the third wireless module 132.

[0113] In this embodiment, the first wireless module 112, the second wireless module 122, the third wireless module 132 and the wireless communication module 142 are preferably Bluetooth modules, but are not limited thereto. For example, a Wi-Fi module or a radio frequency identification (RFID) module may also be used to achieve wireless connection.

[0114] In summary, since the child safety seat safety warning system 100 of the present invention has a first detection device 110, a second detection device 120, and a third detection device 130, the three are respectively used to detect the installation and fastening status of the top strap 230, the ISOFIX connector 240, and the buckle 250 and send out a first detection signal, a second detection signal, and a third detection signal. When the relay control device 140 does not receive at least one of the first, second, and third detection signals, an alarm signal is sent to remind the user whether the installation and fastening status of the top strap 230, the ISOFIX connector 240, and the buckle 250 are correct, so as to ensure the safety and comfort of infants and young children riding in the car, while improving the installation efficiency of the child safety seat 200.

[0115] The structures of other parts of the child safety seat 200 involved in the present invention are conventional arrangements well known to those skilled in the art and will not be described in detail here.

[0116] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope 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 of the present invention.
