Description

Technical Field

[0001] The present disclosure relates to the field of child product technologies, and in particular, to child safety seats, safety belt wearing promotion systems, and safety belt wearing promotion methods.

Background Art

[0002] Child safety seats generally have side impact protection blocks near the vehicle door. When the vehicle collides, the side impact protection blocks buffer the impact from the side, thereby improving the safety of the child safety seat. In order to reduce manufacturing costs and facilitate transportation, the side impact protection blocks are designed to be detachable. During use, it is necessary to attach the side impact protection blocks to the side of the child safety seat close to the vehicle door. However, in actual use, the user may forget to install the side impact protection blocks (failure to install). Alternatively, after installing the side impact protection blocks, the usage mode of the child safety seat (for example, the forward-facing usage mode and the rear-facing usage mode) changes, and the user may forget to adjust the installation position of the side impact protection blocks (misinstallation). As a result, the side impact protection blocks cannot perform their original functions during a collision, and the safety of the child safety seat decreases.

[0003] Furthermore, most child safety seats can be rotated as needed and can switch between the forward-facing usage mode and the rear-facing usage mode. Young children, such as those under 15 months old, need to adopt the rear-facing usage mode to maximize safety. However, most currently commercially available child safety seats are difficult to effectively prevent misuse.

[0004] Furthermore, child safety seats are devices designed for children of different weights and ages. Children in the vehicle are restrained by the child safety seat, which can reduce the impact force on the child during a vehicle collision or sudden deceleration and limit the movement of the child's body, thereby reducing the child's injury and effectively improving the safety of child riding.

Summary of the Invention

Problems to be Solved by the Invention

[0005] To ensure the stability of the child safety seat and the safety of the child, the child safety seat and the child sitting therein are generally fixed together on the vehicle seat by the vehicle safety belt. However, due to the user's negligence, if the child safety seat is not fixed through the vehicle safety belt, the safety of the child will be at risk.

[0015] To facilitate understanding of the present disclosure, a more comprehensive description of the present disclosure will be given below with reference to the accompanying related drawings. Preferred embodiments of the present disclosure are shown in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more complete understanding of the content disclosed in the present disclosure.

[0016] It should be noted that when an element is said to be "fixed to" another element, the element may be directly disposed on the other element or there may be intermediate elements. When an element is said to be "connected to" another element, it may be directly connected to the other element or intermediate elements may coexist. The terms "disposed", "one end", "the other end" and similar expressions used herein are for illustrative purposes only. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent a specific embodiment. The term "and / or" used herein includes any combination of one or more of the related listed items.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the present disclosure. The terms used herein in the specification of the present disclosure are for the purpose of describing particular embodiments only and are not intended to limit the present disclosure.

[0018] Referring to FIGS. 1 and 2, FIGS. 1 and 2 are diagrams showing a child carrier such as a child safety seat according to an embodiment of the present disclosure from different viewing angles. The child safety seat includes a seat body 1 and a seat base 2. The seat body 1 is pivotally connected to the seat base 2, and the usage mode of the seat body 1 can be changed. Specifically, the seat body 1 can switch between a forward-facing usage mode and a rear-facing usage mode. On two side surfaces of the seat body 1, there are respectively provided side impact protection block attachment positions 200 for detachably attaching side impact protection blocks 100. FIG. 1 shows the side impact protection block 100 attached to the right side of the seat, but this is only an example. It should be noted that the user can attach the side impact protection block to any of the side impact protection block attachment positions 200 according to the usage requirements.

[0019] The seat base 2 includes an International Organization for Standardization FIX (isofix) connector 300 used to engage and connect to the isofix interface of the vehicle seat in order to fixedly connect the child safety seat to the vehicle seat. Optionally, if the seat base 2 can be fixedly connected to the mating interface or connector of the vehicle seat, other types of connectors or interfaces can also be used, and it is not limited in the present disclosure. FIG. 3 shows the child safety seat of FIG. 1 with the usage mode changed. For example, the child safety seat switches from the rear-facing usage mode to the forward-facing usage mode, and vice versa.

[0020] Also, in the embodiments shown in FIGS. 1 to 3, since the side impact protection block 100 is detachably attached to the side impact protection block attachment position 200, there is a possibility that the user may forget to attach the side impact protection block 100 (forget to attach). Also, even if the side impact protection block 100 is attached, there is a possibility that the user may forget to adjust the attachment position of the side impact protection block 100 (misattachment) after the usage mode of the seat body 1 has changed.

[0021] Referring to FIGS. 4, 5, and 13 together, a safety prompt system 10 according to an embodiment of the present disclosure is provided. The safety prompt system 10 includes at least a side impact protection block 100, a first detection device 110, a first control module 120 (shown in FIG. 13), and a first display device 130 (shown in FIG. 13). The child safety seat has an opening 203h at a side impact protection block mounting position 200. Further, the opening 203h is provided on the outer surface side of the seat body 1. Further, the seat body 1 of the present embodiment includes a seat housing 210 and a first mounting seat 203. The opening 203h is defined by the first mounting seat 203. The seat housing 210 is provided with a mounting hole 2101. The first mounting seat 203 is disposed in the mounting hole 2101 and is used to receive the side impact protection block 100. Therefore, the side impact protection block 100 is detachably attached to the side impact protection block mounting position 200.

[0022] As shown in FIG. 4, the side impact protection block 100 includes a shell 101, a first locking mechanism 102, and an unlocking portion 103. The shell 101 defines an accommodation space. The first locking mechanism 102 partially protrudes from the shell 101 so that the side impact protection block 100 can be locked at the side impact protection block mounting position 200. The unlocking portion 103 is partially disposed in the accommodation space of the shell 101 and may be exposed on the first side surface 1011 or the second side surface 1012 of the shell 101. In the present embodiment, the unlocking portion 103 is exposed on the first side surface 1011 of the shell 101. The unlocking portion 103 is configured to unlock the first locking mechanism 102 at the side impact protection block mounting position 200. Optionally, the unlocking portion 103 is a button portion.

[0023] As shown in FIG. 5, the first detection device 110 is disposed on the child safety seat 1, near the side impact protection block mounting position 200, and configured to detect whether the side impact protection block 100 is attached to the side impact protection block mounting position 200 and transmit a first detection signal indicating the detection result. In an embodiment, two first detection devices 110 can be provided, and these first detection devices 110 are respectively arranged near the side impact protection block mounting positions 200 on two sides of the seat body 1.

[0024] Referring together to FIGS. 6 to 8, FIGS. 6 to 8 show the internal structure of the side impact protection block mounting position 200 and the specific structure of the first detection device 110. In an embodiment according to the present disclosure, the child safety seat includes a decorative cover 201 and a second locking mechanism 202 disposed at the side impact protection block mounting position 200. The decorative cover 201 is movably disposed at the side impact protection block mounting position 200 and covers the opening 203h. Specifically, in the present embodiment, the decorative cover 201 is movably disposed at the opening 203h of the first mounting seat 203, and the second locking mechanism 202 is disposed on the first mounting seat 203, but the present disclosure is not limited thereto. In another embodiment, the child safety seat may alternatively not have the first mounting seat 203, and the opening 203h may be defined in the seat body 1.

[0025] The decorative cover 201 includes a cover body 2010 and a third locking mechanism 2013. The third locking mechanism 2013 is disposed on the cover body 2010 and extends from the lower surface of the cover body 2010 toward the bottom surface of the opening 203h. In the present embodiment, a second elastic member 204 is further disposed in the opening 203h. The second elastic member 204 constantly applies a pressing force to the decorative cover 201 so that the decorative cover 201 constantly tends to move away from the bottom surface of the opening 203h. In the present embodiment, the second elastic member 204 is a spring. One end of the spring is connected to the lower surface of the cover body 2010, and the other end of the spring is connected to the bottom surface of the opening 203h, constantly applying a pressing force to the decorative cover 201 so that the decorative cover 201 constantly tends to move away from the bottom surface of the opening 203h. Optionally, the second elastic member 204 may be another elastic assembly such as a torsion spring or an elastic piece, which is not limited in this specification.

[0026] Furthermore, a second locking mechanism 202 is disposed on the inner wall of the opening 203h (or the first mounting seat 203). By fitting and locking with the third locking mechanism 2013, the second locking mechanism 202 can limit the movement stroke in the direction of separating from the bottom surface of the opening 203h of the decorative cover 201, so that the decorative cover 201 cannot continuously move in the direction of separating from the bottom surface of the opening 203h. Specifically, in the present embodiment, the second locking mechanism 202 includes a first slot 2021 and a second slot 2022, and the third locking mechanism 2013 includes a third hook portion 2011 and a fourth hook portion 2012. When the decorative cover 201 slides to a position in the direction of separating from the bottom surface of the opening 203h under the pressing force of a second elastic member 204 which is a spring for example, the third hook portion 2011 and the fourth hook portion 2012 respectively enter the first slot 2021 and the second slot 2022. Thereby, the third hook portion 2011 and the fourth hook portion 2012 are respectively engaged and locked with the first slot 2021 and the second slot 2022, so that the decorative cover 201 cannot continuously slide in the direction of separating from the bottom surface of the opening 203h. In this case, the decorative cover 201 can completely cover the opening 203h and is in the closed position.

[0027] The shapes of the third hook portion 2011 and the fourth hook portion 2012 are designed such that when the third hook portion 2011 and the fourth hook portion 2012 are respectively engaged and locked with the first slot 2021 and the second slot 2022, the continuous sliding of the decorative cover 201 in the direction of separating from the bottom surface of the opening 203h is blocked, and the sliding of the decorative cover 201 in the direction of approaching the bottom surface of the opening 203h is allowed. That is, when an external force capable of overcoming the elastic force of the second elastic member 204 acts on the decorative cover 201, the third hook portion 2011 and the fourth hook portion 2012 can be easily disengaged from the first slot 2021 and the second slot 2022 respectively, whereby the engagement and locking with the first slot 2021 and the second slot 2022 are released.

[0028] Referring further to FIG. 8, the first detection device 110 includes a sensing assembly 111, a first sensing device 112, and a third elastic member 113. The sensing assembly 111 can reciprocate between a non-detection position P1 and a detection position P2. When moving toward the bottom of the opening 203h, the decorative cover 201 can press the sensing assembly 111 from the non-detection position P1 to the detection position P2. The first sensing device 112 is disposed in the vicinity of the sensing assembly 111. When the sensing assembly 111 is at the detection position P2, the first sensing device 112 can detect the sensing assembly 111 and transmit a first detection signal, which will be further described below with reference to FIGS. 10 to 12. The third elastic member 113 always acts on the sensing assembly 111 with a pressing force, so that the sensing assembly 111 always has a tendency to move away from the detection position P2 to the non-detection position P1. In the present embodiment, the first sensing device 112 is a photoelectric detection device, such as a photoelectric sensor, and has a transmitting end and a receiving end. The sensing assembly 111 may be used as a block piece or a plastic assembly. Optionally, other suitable assemblies and sensing devices can be alternatively selected as the sensing assembly 111 and the first sensing device 112. For example, the sensing assembly 111 may be a metal assembly, a magnetic assembly, etc., and the first sensing device 112 may be a metal detection device, a magnetic detector, etc., which are not limited in the present disclosure. In FIG. 8, the decorative cover 201 is in the closed position and not in contact with the sensing assembly 111, so the sensing assembly 111 is at the non-detection position P1 under the action of the third elastic member 113. Optionally, the third elastic member 113 may be a spring, a torsion spring, an elastic piece, etc. Preferably, the third elastic member 113 is a spring.

[0029] Referring to FIGS. 9 and 10 together, FIGS. 9 and 10 show a state in which the side impact protection block 100 is attached to the side impact protection block attachment position 200. In the present embodiment, the first locking mechanism 102 of the side impact protection block 100 includes a first hook portion 1021, a second hook portion 1022, and a first elastic member 1023. The first hook portion 1021 and the second hook portion 1022 project at least partially from different sides of the shell 101.

[0030] Specifically, in this embodiment, the first hook portion 1021 is at least partially disposed within the accommodation space of the shell 101 and can project from the first side portion 1011 of the shell 101. The second hook portion 1022 is at least partially disposed within the accommodation space of the shell 101 and can project from the second side portion 1012 opposite to the first side portion 1011 of the shell 101. Further, the first hook portion 1021 and the second hook portion 1022 are rotatably disposed within the shell 101.

[0031] The first elastic member 1023 is disposed within the accommodation space of the shell 101 and is connected between the first hook portion 1021 and the second hook portion 1022. The first elastic member 1023 causes the first hook portion 1021 and the second hook portion 1022 to tend to move in a direction of always separating. That is, the first elastic member 1023 biases the first hook portion 1021 to project from the first side portion 1011 and biases the second hook portion 1022 to project from the second side portion 1012. When the side impact protection block 100 is worn, the user presses the decorative cover 201 through the side impact protection block 100 and overcomes the pressing force of the second elastic member 204. In this case, the third hook portion 2011 and the fourth hook portion 2012 are disengaged from the first slot 2021 and the second slot 2022 respectively, and the decorative cover 201 slides in a direction close to the bottom of the opening 203h.

[0032] When the side impact protection block 100 enters and locks into the opening 203h, the installation of the side impact protection block 100 is completed. When the first hook portion 1021 and the second hook portion 1022 are at the same height as the first slot 2021 and the second slot 2022 respectively, due to the action of the first elastic member 1023, the first hook portion 1021 and the second hook portion 1022 protrude from the first side portion 1011 and the second side portion 1012 respectively, enter the first slot 2021 and the second slot 2022 respectively, and engage and lock with the first slot 2021 and the second slot 2022 respectively. In this case, the side impact protection block 100 cannot move continuously towards the bottom of the opening 203h or move away from the bottom of the opening 203h. That is, the side impact protection block 100 is fixed to the opening 203h of the side impact protection block mounting position 200. In this embodiment, the first elastic member 1023 is a spring. Optionally, the second elastic member 1023 may be other elastic assemblies such as a torsion spring or an elastic piece, and the present invention is not limited thereto.

[0033] Referring to FIG. 10, in this embodiment, the unlocking portion 103 is a button portion. The unlocking portion 103 is connected to one of the first hook portion 1021 and the second hook portion 1022, and further, the unlocking portion 103 is connected (for example, rotatably connected, slidably connected, or in contact) to the other of the first hook portion 1021 and the second hook portion 1022, and when the unlocking portion 103 is operated, the first hook portion 1021 and the second hook portion 1022 are driven to move synchronously.

[0034] Furthermore, in this embodiment, the button part is at least partially disposed within the shell 101 and is disposed on the second side portion 1012 of the shell 101. The button part is connected to the second hook part 1022. Preferably, the button part is integrally formed with the second hook part 1022, and the button part is further rotatably connected to the first hook part 1021. As shown in FIG. 10, the position where the button part is connected to the first hook part 1021 and the hook part 10210 of the first hook part 1021 are located on opposite sides of each other across the rotation axis of the first hook part 1021. The position where the button part is connected to the second hook part 1022 and the hook part 10220 of the second hook part 1022 are located on the same side of each other across the rotation axis of the second hook part 1022. Thus, for example, when an external force is applied to the unlocking part 103 which is the button part, for example, when the unlocking part 103 is pushed, the unlocking part 103 can move the first hook part 1021 and the second hook part 1022 synchronously, for example, rotate or translate them, so as to drive the hook parts 10210 and 10220 of both to approach each other.

[0035] Specifically, when the side impact protection block 100 is fixedly connected to the opening 203h (see FIG. 10), when the button part is pushed toward the inside of the shell 101, the second hook part 1022 can retract toward the inside of the shell 101 synchronously with the button part, the second hook part 1022 no longer protrudes from the second side portion 1012, and can be disengaged from the second slot 2022. At the same time, the first hook part 1021 can rotate as the button part retracts, the first hook part 1021 no longer protrudes from the first side portion 1011, and can be disengaged from the first slot 2021. In this way, when the button part is pushed, the first hook part 1021 and the second hook part 1022 are respectively disengaged from the first slot 2021 and the second slot 2022. Thereby, the fixed connection of the side impact protection block 100 at the opening 203h of the side impact protection block mounting position 200 is released, and the side impact protection block 100 can be removed from the side impact protection block mounting position 200.

[0036] Optionally, the unlocking portion 103 may be disposed on the first side portion 1011. In this case, the first hook portion 1021 and the second hook portion 1022 may be arranged in opposite ways. Specifically, the button portion is at least partially disposed within the shell 101 and is disposed on the first side portion 1011 of the shell 101. The button portion is firmly connected to the first hook portion 1021. Preferably, the button portion is integrally formed with the first hook portion 1021, and the button portion is further rotatably connected to the second hook portion 1022. When the side impact protection block 100 is fixedly connected within the opening 203h (see FIG. 10), when the button portion is pushed toward the inside of the shell 101, the first hook portion 1021 retreats toward the inside of the shell 101 in synchronization with the button portion, and the first hook portion 1021 no longer protrudes from the first side portion 1011 and is disengaged from the first slot 2021. At the same time, the second hook portion 1022 pivots as the button portion retreats, and the second hook portion 1022 no longer protrudes from the second side portion 1012 and is disengaged from the second slot 2022. In this way, when the button portion is pressed, the first hook portion 1021 and the second hook portion 1022 are disengaged from the first slot 2021 and the second slot 2022, respectively, whereby the fixed connection of the side impact protection block 100 at the opening 203h of the side impact protection block mounting position 200 is released, and the side impact protection block 100 can be disassembled from the side impact protection block mounting position 200.

[0037] In FIG. 10, the side impact protection block 100 is attached to the opening 203h of the side impact protection block attachment position 200. In this case, the decorative cover 201 does not cover the opening 203h and is in an open state. The third hook portion 2011 and the fourth hook portion 2012 of the decorative cover 201 pass through the perforated portion (not numbered) at the bottom of the first attachment sheet 203 and extend below the first attachment sheet 203. The third hook portion 2011 is pressed against the step surface 1110 of the sensing assembly 111, and the sensing assembly 111 overcomes the elastic force of the third elastic member 113 and moves from the non-detection position P1 to the detection position P2. In this way, the first sensing device 112 can sense the sensing assembly 111 and transmit the first detection signal.

[0038] In this embodiment, the depth H of the opening 203h may be equal to or greater than the distance h between the detection position P2 and the non-detection position P1. Alternatively, when the side impact protection block 100 is inserted into and attached to the opening 203h, the length of the insertion portion of the side impact protection block 100 may be equal to or greater than the distance h between the detection position P2 and the non-detection position P1. In this way, after the side impact protection block 100 is inserted into the opening 203h, the sensing assembly 111 can be surely sensed by the first sensing device 112. Also, false sensing due to accidental contact of the decorative cover 201 can be prevented.

[0039] In other embodiments, the decorative cover 201 is not used, and the side impact protection block 100 has a driving portion extending along its attachment direction. When the side impact protection block 100 is inserted into the opening 203h, the side impact protection block 100 presses the sensing assembly 111 via the driving portion, and the sensing assembly 111 moves from the non-detection position P1 to the detection position P2. In such an embodiment, the length of the insertion portion of the side impact protection block 100 may be equal to or greater than the distance h between the detection position P2 and the non-detection position P1.

[0040] Figures 11 and 12 show the specific structures of the sensing assembly 111 and the first sensing device 112. In one embodiment, the sensing assembly 111 includes a sensing sheet 1111, and the detection groove 1121 is defined between the transmitting end and the receiving end of the first sensing device 112. When the sensing sheet 1111 enters the detection groove 1121, the first detection device 112 detects the sensing assembly 111 and transmits a first detection signal.

[0041] Figure 13 is a functional block diagram of a safety prompt system according to an embodiment of the present invention. In the embodiment of the present invention, the safety prompt system 10 includes not only the first detection device 110, but also the first control module 120 and the first display device 130. As described above, the first detection device 110 can be disposed within the child safety seat. The specific structure and components of the first detection device 110 can be obtained with reference to the foregoing embodiments. Details are not described herein again.

[0042] The first control module 120 can be disposed within the child safety seat. Specifically, the first control module 120 can be disposed on the seat body 1 or the seat base 2. Preferably, the first control module 120 is disposed on the seat base 2. The first control module 120 is, for example, a microcontroller or a processor, but is not limited thereto in the present invention. Further, the first control module 120 is communicably connected to each first detection device 110, and the first control module 120 is configured to receive the first detection signal and transmit a control signal.

[0043] The first display device 130 is disposed outside the child safety seat 1 or the child safety seat and is communicably connected to the first control module 120. The first display device 130 is configured to receive a control signal from the first control module 120 and transmit reminder information when the side impact protection block 100 is not attached to the side impact protection block attachment position 200. Optionally, the first display device 130 includes at least one of at least a buzzer, a vibrator, a display screen, a mobile phone, and a tablet computer. Preferably, the first display device 130 is attached to a display screen 131 on the seat body 1 or the seat base 2. More preferably, the first display device 130 is a mobile phone. In this embodiment, the first display device 130 includes a display screen 131 and an input interface 132, but the present invention is not limited thereto.

[0044] Note that the first control module 120 may be communicably connected to the first detection device 110 and the first display device 130 wirelessly or by wire. In one embodiment, both the first control module 120 and the first display device 130 are disposed on the seat base 2, and the first control module 120 and the first display device 130 may be electrically connected via a circuit disposed in the seat base 2. Further, a circuit electrically connected to the first detection device 110 may be disposed in the seat body 1 and electrically connected to the first control module 120. When the seat body 1 is assembled on the seat base 2, the first detection device 110 may be electrically connected to the first control module 120 via a circuit disposed in the seat body 1. Also, in one embodiment, a power supply device (e.g., a battery) may be disposed in the child safety seat to supply power to the safety prompt system 10, but the present invention is not limited thereto. In other embodiments, the child safety seat may be electrically connected to a vehicle power system.

[0045] The display screen 131 may be configured to display reminder information. The reminder information may be presented by at least one of text, image, symbol, and animation. The reminder information may instruct the user to input the attachment position of the child safety seat on the vehicle via the input interface 132. For example, input whether the child safety seat is in the left seat or the right seat of the vehicle via the input interface 132. After receiving the attachment position information of the child safety seat via the input interface 132, the first control module 120 can again instruct the user to attach the side impact protection block 100 to the correct side impact protection block attachment position 200 via the first display device 130, such as the display screen 131. Optionally, in an embodiment, the display screen 130 is a touch display screen, and the input interface 132 may be an operation interface displayed on the display screen 130. According to the prompt on the operation interface displayed on the display screen 130, the user inputs the attachment position of the child safety seat on the vehicle by a touch operation.

[0046] Optionally, the safety prompt system 10 further includes at least one second detection device 140. The second detection device 140 is communicably connected to the first control module 120. It should be noted that the second detection device 140 may be arranged at the isofix connector 300 of the child safety seat or the isofix interface (not shown) of the vehicle seat, and may be configured to detect the connection state of the isofix connector 300 and transmit a second detection signal indicating the connection state.

[0047] The first control module 120 can receive a second detection signal and, based on the second detection signal, obtain whether the child safety seat is attached to the vehicle seat. If it is attached, the first control module 120 can notify, via the first display device 130, for example, a display screen 131 arranged on the child safety seat, to input the attachment position information of the child safety seat. In this way, the first control module 120 can determine whether the child safety seat is currently attached to the left seat or the right seat of the vehicle, thereby providing conditions for the first control module 120 to correctly determine the correct attachment position of the side impact protection block thereafter.

[0048] In one embodiment of the present invention, the second detection device 140 is arranged on the isofix interface of the vehicle seat, and the second detection signal transmitted by the second detection device 140 includes the position information of the vehicle seat corresponding to the isofix interface. For example, when the second detection device 140 is arranged on the isofix interface of the left seat of the vehicle, the second detection signal transmitted by the second detection device 140 may indicate whether the child safety seat is connected to the left seat of the vehicle. In other words, the first control module 120 can determine whether the child safety seat is attached to the left seat or the right seat of the vehicle based on the second detection signal. In this embodiment, there is no need to arrange an input interface 132 for inputting whether the child safety seat is attached to the left seat or the right seat of the vehicle.

[0049] In other embodiments of the present invention, the first display device 130 may be an electronic device outside the child safety seat, such as a mobile phone or a tablet computer. The second detection signal may be transmitted to the electronic device (the first display device 130) via a wireless device. The user is instructed to input, through the display of the electronic device, whether the child carrier is currently attached to the seat on the left side of the vehicle or the seat on the right side of the vehicle. Thereby, the first control module 120 can accurately determine the attachment position of the side impact protection block 100 based on the attachment position information input by the user.

[0050] The first display device 130 can display the current attachment position of the child safety seat and transmit reminder information if the side impact protection block 100 is not attached to the side impact protection block attachment position 200 corresponding to the current attachment position of the child carrier.

[0051] In one embodiment of the present invention, the safety prompt system 10 may include a plurality of second detection devices 140. The plurality of second detection devices 140 can be respectively arranged on the isofix interfaces of different vehicle seats. Each of the second detection devices 140 can be configured to sense the connection state of the corresponding isofix interface and transmit a second detection signal indicating the connection state. The first control module 120 can determine the connection state of the isofix interface and whether the child safety seat is attached to the left seat or the right seat of the vehicle based on the second detection signals transmitted by the plurality of second detection devices 140.

[0052] In an embodiment according to the present disclosure, the safety prompt system 10 further includes a third detection device 150. The third detection device 150 is disposed on the child safety seat and communicatively connected to the first control module 120. The third detection device 150 is configured to detect the usage mode of the child safety seat and transmit a third detection signal indicating the usage mode. The first control module 120 can receive the third detection signal and, based on the third detection signal, obtain whether the usage mode of the child safety seat is the forward usage mode or the rearward usage mode. The first control module 120 controls the first display device 130 to display the current usage mode of the child safety seat, and when the side impact protection block 100 is not attached to the side impact protection block attachment position 200 corresponding to the usage mode, the first control module 120 controls the first display device 130 to transmit reminder information.

[0053] In an embodiment of the present invention, the safety prompt system 10 further includes a fourth detection device 160. The fourth detection device 160 is disposed within the safety belt buckle of the child safety seat and communicatively connected to the first control module 120. The fourth detection device 160 is configured to detect the fastening state of the safety belt buckle and transmit a fourth detection signal indicating the fastening state. The first control module 120 can receive the fourth detection signal and, based on the fourth detection signal, obtain whether the safety belt buckle is fastened. In one embodiment, the first display device 130 is controlled to transmit reminder information only when the first control module 120 receives the fourth detection signal and determines that the safety belt buckle is in the fastened state. When the first control module 120 receives the fourth detection signal and determines that the safety belt buckle is not in the fastened state, the first control module 120 does not transmit a control signal. In this case, the first display device 130 may not transmit reminder information.

[0054] Hereinafter, the operation flow of the safety prompt system 10 according to the embodiment of the present disclosure will be described in detail.

[0055] In one embodiment, referring to FIG. 8, when the side impact protection block 100 is not provided at the side impact protection block mounting position 200, the first sensing device 112 of the first detection device 110 does not detect the sensing assembly 111, and the first sensing device 112 transmits a first detection signal indicating "not mounted" to the first control module 120. The first control module 120 receives the first detection signal and transmits a control signal to the first display device 130 to control the first display device 130 to transmit reminder information. For example, the first display device 130 may be attached to the seat body 1 and include a display screen 131. The first control module 120 controls the first display device 130 to display prompt information on the display screen 131 to remind the user that the side impact protection block is "not mounted", or transmits a prompt to an electronic device via a wireless signal to realize a "not mounted" reminder.

[0056] In one embodiment, the second detection device 140 is disposed on the isofix connector 300 of the child safety seat. After detecting that the isofix connector 300 of the child safety seat is connected to the corresponding isofix interface of the vehicle seat, the second detection device 140 transmits a second detection signal to the first control module 120. Based on the second detection signal, the first control module 120 determines that the child safety seat is attached to the vehicle seat, and controls the first display device 130, for example, the display screen 131 disposed on the child safety seat, to prompt the user to input the attachment position information of the child safety seat. Based on the attachment position information of the child safety seat input by the user, the first control module 120 determines whether the child safety seat is currently attached to the seat on the left side of the vehicle or the seat on the right side of the vehicle, and then the first control module provides conditions for correctly determining the correct attachment position of the side impact protection block.

[0057] In one embodiment, the second detection device 140 is disposed on the isofix interface of the vehicle seat. After detecting that the isofix connector 300 of the child safety seat is connected to the corresponding isofix interface of the vehicle seat, the second detection device transmits a second detection signal to the first control module 120. Based on the second detection signal, the first control module 120 determines whether the child safety seat is attached to the left seat or the right seat of the current vehicle, and then the first control module provides conditions for correctly determining the correct attachment position of the side impact protection block.

[0058] In one embodiment, when the first detection signal indicates "installed", if the third detection device 150 detects a change in the use mode of the child safety seat, the third detection device 150 transmits a third detection signal indicating whether the current use mode of the seat is the forward use mode or the rearward use mode to the first control module 120. The first control module 120 receives the first detection signal transmitted from the first sensing device 112 at the side impact protection block attachment position 200 corresponding to the current use mode. When the first detection signal indicates "not installed", the first control module 120 transmits a control signal to the first display device 130 to control the first display device 130 to transmit reminder information. Thereby, the "misinstallation" warning is realized.

[0059] In one embodiment, the fourth detection device 160 detects whether the buckle of the safety belt is fastened and transmits a fourth detection signal indicating the fastened state to the first control module 120. When the fourth detection signal indicates that the buckle of the safety belt is not fastened, the first control module 120 may not transmit a control signal of "reminder information" to the first display device 130 in order to implement the "do not interfere" function.

[0060] As shown in FIG. 14, an embodiment of the present invention proposes a child safety seat. The child safety seat includes a seat body 1 and a seat base 2. The seat body 1 is used by an infant or child under about 15 months old, or by a child over 15 months old. It should be noted that when the seat body 1 is used by an infant or child under 15 months old, the seat body 1 must be arranged backward. That is, the infant or child sitting on the seat body 1 needs to face the rear of the vehicle. When the seat body 1 is used by a child over 15 months old, the seat body 1 may be set to a forward use mode or a backward use mode. That is, the child sitting on the seat body 1 may face the front of the vehicle or the rear of the vehicle. As shown in FIGS. 15, 22, and 43, the seat base 2 includes a second attachment seat 401, a turntable 402, a fifth detection device 400, a second control module 50, a second display device 60, an input mechanism 70, and a fourth lock mechanism 800. As shown in FIGS. 15 and 16, the seat body 1 is mounted on the turntable 402, the turntable 402 is rotatably arranged on the second attachment seat 401, and the turntable 402 has a first rotation position (shown in FIG. 15) and a second rotation position (shown in FIG. 16) with respect to the second attachment seat 401. It should be understood that the attachment position of the seat body 1 with respect to the turntable 402 is fixed, and the seat body 1 switches between the forward use mode and the backward use mode as the turntable 402 rotates. Here, the first rotation position and the second rotation position may correspond to the forward use mode and the backward use mode of the turntable 402 and the seat body 1, respectively. Specifically, as shown in FIGS. 17 and 18, the turntable 402 has a rotating upper cover 403 and a rotating lower cover 404 that fit together, and the rotating lower cover 404 is substantially circular. A circular attachment receiving portion 405 is provided at substantially the center of the second attachment seat 401. An annular attachment rib 406 is provided on the second attachment seat 401 along the groove wall of the attachment receiving portion 405.The mounting rib 406 is sandwiched between the upper rotating cover 403 and the lower rotating cover 404, and as shown in FIG. 19, it realizes a rotatable connection between the turntable 402 and the second mounting sheet 401.

[0061] As shown in FIGS. 18 and 28, the fifth detection device 400 includes a detector 410 and a second sensing device 420. Optionally, in some embodiments, the fifth detection device 400 may be the same detection device as the third detection device 150 of the foregoing embodiments.

[0062] Specifically, as shown in FIG. 28, the detector 410 protrudes from the bottom surface of the lower rotating cover 404, and the detector 410 is offset from the rotation center 409 of the lower rotating cover 404, that is, the center of the lower rotating cover 404. The second sensing device 420 includes a first sensor 421 and a second sensor 422. The first sensor 421 and the second sensor 422 are spaced apart and arranged within the mounting receiver 405. When the turntable 402 rotates to the first rotation position, the detector 410 triggers the first sensor 421 to generate a detection signal. When the turntable 402 rotates to the second rotation position, the detector 410 triggers the second sensor 422 to generate a detection signal. In one embodiment, the detector 410 is a convex rib structure.

[0063] In one embodiment, the first sensor 421 is a first infrared sensor, and the second sensor 422 is a second infrared sensor. When the detector 410 is within the sensing range of the first infrared sensor or the second infrared sensor, the infrared sensor is activated to generate a detection signal. In another embodiment, the first sensor 421 is a first mechanical switch sensor, and the first mechanical switch sensor has a first switch lever (not shown). The second sensor 422 is a second mechanical switch sensor, and the second mechanical switch sensor has a second switch lever (not shown). The detector 410 is configured to generate a detection signal by toggling the first switch lever or the second switch lever to switch the first mechanical switch sensor or the second mechanical switch sensor between on / off states. In this embodiment, as shown in FIG. 18, both the first sensor 421 and the second sensor 422 are optoelectronic sensors. The first sensor 421 has a first transmitting end 421a and a first receiving end 421b arranged opposite to each other, and the first transmitting end 421a is configured to transmit an optical signal to the first receiving end 421b. The second sensor 422 has a second transmitting end 422a and a second receiving end 422b arranged opposite to each other, and the second transmitting end 422a is configured to transmit an optical signal to the second receiving end 422b. When the detector 410 is located between the first transmitting end 421a and the first receiving end 421b, due to the interference of the detector 410, the first receiving end 421b cannot receive the optical signal from the first transmitting end 421a, whereby the first sensor 421 generates a detection signal. Similarly, when the detector 410 is located between the second transmitting end 422a and the second receiving end 422b, the second receiving end 421b cannot receive the optical signal from the second transmitting end 422a due to the shielding of the detector 410, and the second sensor 422 generates a detection signal. The types of the first sensor 421 and the second sensor 422 are not limited to the above infrared sensors, mechanical switch sensors, or optoelectronic sensors, and may be other types of proximity sensors or limit switches. The positions of the detector 410 and the second sensing device 420 can also be interchanged. That is, the detector 410 may be arranged on the second mounting sheet 401, or the second sensing device 420 may be arranged on the turntable 402.The numbers of the detector 410 and the second sensing device 420 can be adjusted as needed. For example, the number of the detector 410 can be two, and the number of the second sensing device 420 can be one, etc., but it is not limited thereto.

[0064] Specifically, as shown in FIG. 43, the second control module 50 may be a programmable control module. Optionally, in some embodiments, the second control module 50 may be the same control module as the first control module 120 in the foregoing embodiments. In this embodiment, the second control module 50 is disposed on the second mounting sheet 401. In other embodiments, the second control module 50 may be disposed on the turntable 402 or the sheet body 1. The second control module 50 is communicatively connected to the first sensor 421, the second sensor 422, the second display device 60, and the input mechanism 70. It will be understood that the communication connection herein includes wired communication connection and wireless communication connection.

[0065] The first sensor 421 and the second sensor 422 are configured to transmit the generated detection signals to the second control module 50. The detection signals here include whether the turntable 402 is in the first rotational position or the second rotational position, that is, whether it is in the forward use mode or the backward use mode. The input mechanism 70 may be an input keyboard disposed on the second mounting sheet 401, and the input mechanism 70 is configured to input one or more pieces of information such as the age, weight, height, etc. of the child, that is, the attributes of the child. The second control module 50 receives the child attributes from the input mechanism 70 and the detection signals from the first sensor 421 or the second sensor 422, determines whether the child attributes match the detection signals of the fifth detection device 400, and is configured to output a matching signal. In this embodiment, the second control module 50 transmits the matching signal to the second display device 60. The matching signal here may include whether the child attributes match the forward use mode of the turntable 402 or the backward use mode. As shown in FIGS. 15 and 16, the second display device 60 may be a display screen disposed on the seat base 2, and the second display device 60 is configured to execute at least one of the reproduction of a reminder voice, the display of a reminder text, the display of a reminder image, and the reproduction of a reminder video based on the matching signal. Optionally, in some embodiments, the second display device 60 may be the same display device as the first display device 130 in the foregoing embodiment. For example, when the child attributes do not match the position state of the turntable 402, for example, when a small infant is sitting in the child safety seat in the forward use mode, a warning sound may sound from the display screen, and a related prompt video may be displayed, notifying the caregiver to rotate the turntable 402 within the time limit to adjust the direction of the child safety seat.

[0066] The second mounting sheet 401 is provided with a power switch 4, and the power switch 4 is communicatively connected to the display screen to control the on / off of the display screen. In this way, when not in use, the display screen can be turned off by the power switch 4 to save power. Also, the power switch 4 can be communicatively connected to the second sensing device 420 or the second control module 50 to control the on / off of the second sensing device 420 or the second control module 50. In this way, when not in use, the second sensing device 420 or the second control module 50 can be turned off by the power switch 4 to save power.

[0067] As shown in FIG. 44, in other embodiments, at least one of the input mechanism 70 and the second display device 60 may be omitted. The second control module 50 may be directly communicatively connected to the mobile terminal 3, such as by a wired communication connection or a wireless communication connection. The mobile terminal 3 may be a mobile phone, a tablet computer, a vehicle central control device, or the like. The second control module 50 may be configured to receive the attributes of the child input via the mobile terminal 3, or to receive the matching signal transmitted by the second control module 50 and notify the caregiver whether the attributes of the child match the position state of the turntable 402. In this way, the caregiver can remotely monitor the usage status of the child safety seat, which is more intelligent and convenient. In other embodiments, the mobile terminal 3 may be the input mechanism 70, and the second control module 50 may be communicatively connected to the input mechanism 70.

[0068] As shown in FIGS. 21 to 23, FIG. 29, and FIG. 30, in one embodiment, the fourth locking mechanism 800 includes a lock assembly 810, a first operation assembly 820, a linkage assembly 830, and a second operation assembly 840.

[0069] In this embodiment, as shown in FIGS. 21 to 23, the lock assembly 810 includes a lock member 811, a first lock hole 812, a second lock hole 813, and a lock reset member 814 (second reset member). The lock member 811 is slidably disposed within the turntable 402, and the lock member 811 can move so as to protrude from the bottom surface of the rotary lower cover 404. The first lock hole 812 and the second lock hole 813 are respectively disposed at the front end and the rear end of the second mounting sheet 401. Specifically, at the front end and the rear end of the second mounting sheet 401, reinforcing iron plates 407 protruding toward the mounting receiving portion 405 are respectively disposed, and the first lock hole 812 and the second lock hole 813 are respectively disposed on the two reinforcing iron plates 407. Since the second mounting sheet 401 is relatively fixed to the vehicle, the front and rear of the second mounting sheet 401 coincide with the front and rear of the vehicle. When the turntable 402 is in the first rotational position, that is, in the forward use mode, the lock member 811 can be inserted into the first lock hole 812. When the turntable 402 is in the second rotational position, that is, in the rearward use mode, the lock member 811 can be inserted into the second lock hole 813. Both ends of the lock reset member 814 (second reset member) are respectively in contact with both ends of the lock member 811 and a fixed sheet 837 (details will be described later), and the lock reset member 814 (second reset member) biases the lock member 811 to move in a direction approaching the second mounting sheet 401.

[0070] In other embodiments, the lock assembly 810 may be of other types. For example, the positions of the lock member 811, the first lock hole 812, and the second lock hole 813 can be changed. That is, the lock member 811 is slidably disposed on the second mounting sheet 401, and the first lock hole 812 and the second lock hole 813 are respectively disposed at the front end and the rear end of the turntable 402. Further, the lock assembly 810 does not necessarily have to be in a form in which the lock member 811 is attached to the lock hole, and may be in a form in which a hook is attached to a buckle. Briefly speaking, if the lock assembly 810 has a first fitting portion disposed on one of the turntable 402 and the second mounting sheet 401, and a second fitting portion and a third fitting portion disposed on the other of the turntable 402 and the second mounting sheet 401, and the first fitting portion is locked and fitted with the second fitting portion when the turntable 402 is in the first rotational position, and the first fitting portion is locked and fitted with the third fitting portion when the turntable 402 is in the second rotational position, the functions of locking and unlocking between the turntable 402 and the second mounting sheet 401 can be realized.

[0071] Specifically, as shown in FIGS. 22, 24, and 25, the first operation assembly 820 includes a first operation member 821 and a first reset member 822. The first operation member 821 may be a pull handle slidably disposed on the back side of the turntable 402. Note that since the turntable 402 is rotatable with respect to the vehicle, it should be noted that the front and rear here refer to the front and rear of the turntable 402, not the front and rear of the turntable 402 with respect to the front of the vehicle. Specifically, the front side of the turntable 402 refers to the side that engages with the end portion far from the backrest of the vehicle safety seat body 1, and the rear side of the turntable 402 refers to the side that engages with the end portion close to the backrest of the vehicle safety seat body 1. For example, as shown in FIGS. 14 and 15, the front end of the turntable 402 refers to the end portion close to the second display device 60 of the turntable 402, that is, the lower end of the turntable 402, and the rear end of the turntable 402 refers to the end portion far from the second display device 60 of the turntable 402, that is, the upper end of the turntable 402. As shown in FIG. 16, when the turntable 402 rotates from the first rotation position to the second rotation position, the rear end of the turntable 402 approaches the second display device 60, and the front end of the turntable 402 moves away from the second display device 60. As shown in FIGS. 21 and 22, the first reset member 822 is located at the upper end of the first operation member 821, and both ends of the first reset member 822 are in contact with the first operation member 821 and the turntable 402, respectively. Specifically, the rotating upper cover 403 and the rotating lower cover 404 enclose to form an accommodation cavity 408, and both the first reset member 822 and the first operation member 821 are located in the accommodation cavity 408, and both ends of the first reset member 822 are in contact with the first operation member 821 and the rotating upper cover 403, respectively. Therefore, the first reset member 822 biases the first operation member 821 to move in a direction approaching the rotating lower cover 404, that is, in a direction approaching the second mounting seat 401.

[0072] Specifically, as shown in FIGS. 22 and 24 to 27, the linkage assembly 830 includes a linkage member 831, a pressing member 832, a third reset member 833, a connecting member 836, and a fixing sheet 837.

[0073] As shown in FIGS. 22 and 25, the linkage member 831 is rotatably disposed within the accommodation cavity 408. The linkage member 831 has a substantially L-shaped structure and includes a first end 831a, a second end 831b, and a third end 831c. The first end 831a is located at the corner of the L-shaped structure, and the second end 831b and the third end 831c are located at both ends of the L-shaped structure, respectively. The first end 831a is pivotally connected to the turntable 402, specifically, pivotally connected to the rotating upper cover 403. The second end 831b is connected to the locking member 811. As shown in FIG. 27, specifically, the fixed seat 837 is fixed to the rotating lower cover 404, the locking member 811 is movably disposed within the fixed seat 837, a driving chute 837a arranged substantially along the vertical direction is provided on the side wall of the fixed seat 837, a strip groove 831d is provided on the second end 831b, and the strip groove 831d extends generally along the direction from the second end 831b toward the first end 831a. One end of the connecting member 836 is inserted into the strip groove 831d, and the other end of the connecting member 836 passes through the driving chute 837a and is connected to the locking member 811. In this embodiment, the connecting member 836 is a rivet. As shown in FIG. 25, a contact rib 821a is provided at the lower end of the first operating member 821, that is, the end close to the second mounting seat 401, and the contact rib 821a contacts the second end 831b and is disposed on the side of the linkage member 831 close to the second mounting seat 401. In this way, as shown in FIG. 22, when the first operating member 821 is moved in the direction away from the second mounting seat 401, that is, in the F1 direction, the first operating member 821 can rotationally drive the linkage member 831 along the F2 direction via the contact rib 821a, and the rotation of the linkage member 831 drives the connecting member 836 to move along the driving chute 837a. The connecting member 836 is fixedly connected to the locking member 811, and the locking member 811 can be driven to move along the direction F1.When the locking member 811 moves so as to withdraw from the first locking hole 812 or the second locking hole 813, the turntable 402 is unlocked from the second mounting sheet 401, and the turntable 402 can rotate with respect to the second mounting sheet 401 to adjust the direction.

[0074] As shown in FIGS. 22 and 25, the pressing member 832 is slidably disposed within the accommodation cavity 408. The pressing member 832 abuts against the third end portion 831c. The third reset member 833 is disposed between the pressing member 832 and the turntable 402. Specifically, the pressing member 832 includes a boss portion 832a and a sleeve portion 832b that are connected to each other. The third reset member 833 sleeves the sleeve portion 832b, and the two end portions of the third reset member 833 abut against the boss portion 832a and the lower rotating cover 404, respectively. In this way, the third reset member 833 biases the pressing member 832 to move in a direction away from the second mounting sheet 401.

[0075] Specifically, as shown in FIGS. 29 and 30, the second operation assembly 840 includes a second operation member 841, a drive member 842, an actuating member 843, a first traction member 844, and a drive reset member (not shown). The second operation member 841 may be a pull handle. In this embodiment, two second operation members 841 are provided, which are respectively arranged on both sides of the seat body 1, and are more convenient than the operation of reaching the back side of the turntable 402 with the hand. The drive member 842 is slidably arranged on the seat body 1 and is movable along a direction intersecting the moving direction of the locking member 811, for example, the direction F3. A slide chute 842a is provided on the drive member 842. One end of the actuating member 843 is provided with a slide guide post 843a that fits into the slide chute 842a. That is, the drive member 842 and the actuating member 843 realize a slidable connection through the cooperation of the slide chute 842a and the slide guide post 843a. The other end of the actuating member 843 abuts against the end of the pressing member 832 on the side away from the second mounting seat 401. The drive reset member is arranged between the drive member 842 and the seat body 1, and the drive reset member biases the drive member 842 to move in a direction opposite to the pulling direction of the first traction member 844, for example, the direction opposite to the direction F3. Two first traction members 844 are provided. Specifically, the first traction member 844 may be a steel wire. Both ends of the first traction member 844 are respectively connected to the second actuating member 841 and the drive member 842. When the second actuating member 841 is pulled, the drive member 842 moves through the first traction member 844. The slide chute 842a gradually moves away from the seat base 2 along the pulling direction of the first traction member 844, for example, the direction F3. Therefore, when the second actuating member 841 is pulled and the drive member 842 moves through the first traction member 844, the actuating member 843 is driven by the slide chute 842a and pressed against the pressing member 832.

[0076] The specific operation procedure of the fourth locking mechanism 800 in this embodiment is as follows.

[0077] When it is necessary to unlock the turntable 402 from the second mounting sheet 401 and rotate the turntable 402 with respect to the second mounting sheet 401, as shown in FIG. 22, when the first operating member 821 is pulled, the first operating member 821 moves in the direction F1, and the first operating member 821 drives the linkage member 831 to rotate along the direction F2. Due to the rotation of the linkage member 831, the connecting member 836 moves along the drive chute 837a. Since the connecting member 836 is fixedly connected to the locking member 811, the locking member 811 can be driven to move along the F1 direction. When the locking member 811 moves, for example, to withdraw from the first locking hole 812, the turntable 402 is unlocked from the second mounting sheet 401. In this case, the turntable 402 is rotatable. For example, the turntable 402 is rotated from the first rotational position to the second rotational position. As a result, as shown in FIGS. 15 and 16, the turntable 402 and the sheet body 1 attached to the turntable 402 are rotated from the forward use mode to the backward use mode. Then, the first operating member 821 is released, and due to the elastic force of the first reset member 822, the first operating member 821 moves in the direction opposite to the F1 direction, and is driven by the linkage member 831 to move the locking member 811 also in the direction opposite to the F1 direction. As shown in FIG. 22, when the locking member 811 moves until it is inserted into the second locking hole 813, the turntable 402 is relatively locked to the second mounting sheet 401. That is, as shown in FIG. 16, the turntable 402 and the sheet body 1 attached to the turntable 402 are locked in the backward use mode.

[0078] As shown in FIGS. 29 and 30, by pulling the second operating member 841 located on both sides of the sheet body 1, the second operating member 841 pulls the driving member 842 via the first pulling member 844 and moves it along the direction F3, and the driving member 842 drives the operating member 843 to move it along the direction opposite to the direction F1. As shown in FIG. 22, the operating member 843 also moves in the direction opposite to the direction F1 by pressing the pressing member 832, and the pressing member 832 drives the linkage member 831 to rotate it along the direction F2. Due to the rotation of the linkage member 831, the connecting member 836 moves along the driving chute 837a. Since the connecting member 836 is fixedly connected to the locking member 811, the locking member 811 is driven to move along the direction F1. When the locking member 811 moves, for example, to retract from the first locking hole 812, the turntable 402 is unlocked from the second mounting sheet 401. In this case, the turntable 402 is rotatable. For example, the turntable 402 rotates from the first rotation position to the second rotation position, that is, as shown in FIG. 16, the turntable 402 and the sheet attached to the turntable 402 are rotated from the forward use mode to the backward use mode. Then, the second operating member 841 is released, the second operating member 841 is reset by the action of a reset spring (not shown) inside it, and the driving member 842 not pulled by the first pulling member 844 moves along the direction opposite to the direction F3 as shown in FIGS. 29 and 30 by the action of the driving reset member. Then, the operating member 843 is driven by the driving member 842 and moves along the direction F1 as shown in FIG. 22. The pressing member 832 not pressed by the operating member 843 moves along the direction F1 by the elastic force of the third reset member 833. At the same time, the locking member 811 moves along the direction opposite to the direction F1 by the elastic force of the lock reset member 814 (the second reset member). When the locking member 811 moves and is inserted into the second locking hole 813, the turntable 402 is relatively locked to the second mounting sheet 401. That is, as shown in FIG. 16, the turntable 402 and the sheet body 1 attached to the turntable 402 are locked in the backward use mode.

[0079] In another embodiment, as shown in FIGS. 35, 39, and 40, the fourth locking mechanism 800 may alternatively include a lock assembly 810, a linkage assembly 830, a second operation assembly 840, and a third operation assembly 850.

[0080] Specifically, as shown in FIGS. 31, 33, and 39, the lock assembly 810 includes a lock member 811, a first lock hole 812, a second lock hole 813, and a second reset member 814. The first lock hole 812 and the second lock hole 813 are respectively disposed on the front and back surfaces of the rotating lower cover 404. As shown in FIG. 31, the lock member 811 is slidably disposed within the mounting receiver 405, specifically, on the front surface of the mounting receiver 405. In other embodiments, the lock member 811 may be disposed on the back side of the mounting receiver 405. As shown in FIG. 39, a reinforcing iron plate 407 is also provided on the front side of the second mounting sheet 401, and the lock member 811 slides so as to protrude from the reinforcing iron plate 407 and is inserted into the first lock hole 812 or the second lock hole 813 to achieve locking between the turntable 402 and the second mounting sheet 401. The second reset member 814 is disposed between the second mounting sheet 401 and the lock member 811. Specifically, both ends of the second reset member 814 are respectively in contact with the lock member 811 and the groove bottom of the mounting receiver 405. In this way, the second reset member 814 biases the lock member 811 to move in a direction approaching the turntable 402.

[0081] Specifically, as shown in FIGS. 32 and 39, the linkage assembly 830 includes a first pressing member 834 and a second pressing member 835. The first pressing member 834 and the second pressing member 835 are slidably disposed within the receiving cavity 408 and are respectively disposed on opposite sides of the first locking hole 812 and the second locking hole 813. The first pressing member 834 and the second pressing member 835 generally have a pin-shaped structure. When the turntable 402 is in the first rotational position, i.e., in the forward use mode, the first pressing member 834 abuts against the end of the locking member 811 protruding from the reinforcing iron plate 407. When the turntable 402 is in the second rotational position, i.e., in the backward use mode, the second pressing member 835 abuts against the end of the locking member 811 protruding from the reinforcing iron plate 407.

[0082] As shown in FIGS. 35 to 37, the structure of the second operation assembly 840 is substantially the same as that of the previous embodiment, except that the second operation assembly 840 of this embodiment includes two drive members, namely a first drive member 845 and a second drive member 846. The second operation assembly 840 further includes two operating members, namely a first operating member 847 and a second operating member 848. One end of each first traction member 844 is connected to the second operating member 841 on both sides of the seat body 1, and the other end of each first traction member 844 sequentially passes through the first drive member 845 and the second drive member 846. Each first traction member 844 has a first engagement protrusion 844a and a second engagement protrusion 844b. The first engagement protrusion 844a and the second engagement protrusion 844b are engaged with the first drive member 845 and the second drive member 846 respectively. Two first engagement protrusions 844a are provided and engaged with both ends of the first drive member 845 respectively. One second engagement protrusion 844b is provided and engaged with the end of the second drive member 846 close to the first drive member 845. The first drive member 845 and the second drive member 846 can be pulled and moved in the F3 direction or the direction opposite to the F3 direction through one first traction member 844 only by pulling the second operation members 841 on both sides of the seat body 1. As shown in FIGS. 38 and 39, the first operating member 847 and the second operating member 848 respectively protrude from the bottom surface of the seat body 1 and abut against one end of the first pressing member 834 and the second pressing member 835 away from the lock member 811, or one end of the first pressing member 834 and the second pressing member 835 away from the lock member 811 protrudes from the rotating upper cover 403 and abuts against the first operating member 847 and the second operating member 848.

[0083] Specifically, as shown in FIGS. 40 to 42, the third operation assembly 850 includes a third operation member 851, a third traction member 852, a third drive member 853, a fourth drive member 854, and a drive reset member 857. The third drive member 853 and the fourth drive member 854 are respectively provided with a third slide chute 853a and a fourth slide chute 854a. The first pressing member 834 and the second pressing member 835 are respectively provided with a third slide guide post 834a and a fourth slide guide post 835a. The third slide chute 853a and the fourth slide chute 854a are respectively attached to the third slide guide post 834a and the fourth slide guide post 835a. In other embodiments, the third operation assembly 850 may further include a third actuating member (not shown) and a fourth actuating member (not shown). The third slide guide post 834a and the fourth slide guide post 835a are disposed on the third actuating member and the fourth actuating member respectively, without sharing the first pressing member 834 and the second pressing member 835 with the second operation assembly 830. The third operation member 851, the third traction member 852, the third drive member 853, the fourth drive member 854, and the drive reset member 857 are all disposed on the turntable 402. Specifically, the third operation assemblies 850 are respectively provided on the left and right sides of the turntable 402. Taking the third operation assembly 850 disposed on one side of the turntable 402 as an example, the third operation assembly 850 includes one third operation member 851 and two third traction members 852. One end of each of the two third traction members 852 is connected to the third operation member 851, and the other ends of the two third traction members 852 are respectively connected to the third drive member 853 and the fourth drive member 854. The structure and function of the third traction member 852 are the same as those of the first traction member 844, and the locking member 811 is also driven to move by pulling the third drive member 853 and the fourth drive member 854. In this embodiment, the third operation member 851 is a pull handle.

[0084] The specific operation procedure of the fourth locking mechanism 800 in this embodiment is as follows.

[0085] When it is necessary to unlock the turntable 402 from the second mounting sheet 401 and rotate the turntable 402 relative to the second mounting sheet 401, as shown in FIGS. 40 to 42, when the third operating member 851 is pulled, the third operating member 851 pulls the third driving member 853 and the fourth driving member 854 through the two third pulling members 852, respectively, and moves them toward each other. For example, the third driving member 853 is pulled and moved along the direction F5. Then, the first pressing member 834 is driven by the third driving member 853 and moves in a direction approaching the second mounting sheet 401, and the second pressing member 835 is driven by the fourth driving member 854 and moves in a direction approaching the second mounting sheet 401. In this case, when the turntable 402 is in the first rotation position, that is, the forward use mode, as shown in FIG. 15, the locking member 811 is inserted into the first locking hole 812, and the second pressing member 835 presses the locking member 811 until the locking member 811 is pushed out of the first locking hole 812, and the locking member 811 also moves in a direction approaching the second mounting sheet 401. In this case, the locking member 811 is completely disengaged from the turntable 402 and is disposed in the mounting receiving portion 405. In this case, the turntable 402 is unlocked from the second mounting sheet 401, and the turntable 402 can be rotated, for example, from the first rotation position to the second rotation position. As a result, as shown in FIGS. 15 and 16, the turntable 402 and the sheet body 1 mounted on the turntable 402 rotate from the forward use mode to the backward use mode. Then, the third operating member 851 is released, and the third operating member 851 is reset by the elastic force of a reset spring (not shown) inside it. The third driving member 853 that is not pulled by the third pulling member 852 moves along the direction opposite to the direction F5 as shown in FIG. 41 under the action of the driving reset member 857. Then, the first pressing member 834 is driven by the third driving member 853 and moves in a direction away from the second mounting sheet 401, and the locking member 811 that is not pressed by the first pressing member 834 moves in a direction away from the second mounting sheet 401 by the elastic force of the second reset member 814 and is inserted into the second locking hole 813.Then, the turntable 402 is locked relative to the second mounting sheet 401. That is, the turntable 402 and the sheet body 1 attached to the turntable 402 are locked in the backward use mode.

[0086] As shown in FIGS. 35 to 37, the second operating members 841 located on both sides of the sheet body 1 may be alternately pulled. The second operating member 841 pulls the first driving member 845 and the second driving member 846 via the first pulling member 844 and moves along the F3 direction. Then, as shown in FIGS. 38 and 39, the first operating member 847 is driven by the first driving member 845 and moves along the direction approaching the second mounting sheet 401, and at the same time, the first pressing member 834 is also pressed and moves along the F4 direction. The second operating member 848 is driven by the second driving member 846 and moves along the direction approaching the second mounting sheet 401, and at the same time, the second pressing member 835 is also pressed and moves along the direction approaching the second mounting sheet 401. In this case, when the turntable 402 is in the first rotational position, that is, the forward use mode, as shown in FIG. 15, the locking member 811 is inserted into the first locking hole 812, and the first pressing member 834 presses the locking member 811 and moves in the direction of F4 until the locking member 811 is pushed out of the first locking hole 812. In this case, the locking member 811 is completely disengaged from the turntable 402 and is disposed in the mounting receiving portion 405. In this case, the turntable 402 is unlocked from the second mounting sheet 401, and the turntable 402 can rotate, for example, from the first rotational position to the second rotational position. As a result, as shown in FIG. 16, the turntable 402 and the sheet body 1 attached on the turntable 402 are rotated from the forward use mode to the backward use mode. In this case, the locking member 811 is located on the side opposite to the second locking hole 813. Next, the second operating member 841 is released, the second operating member 841 is reset by the action of its internal reset spring, the first driving member 845 is reset by the action of a driving reset member (not shown), and the second driving member 846 is driven to move along the direction opposite to the F3 direction via the first pulling member 844. In other embodiments, a driving reset member may be provided on the second driving member 846, and the second driving member 846 may be reset via the driving reset member.Then, the first actuating member 847 is driven by the first driving member 845 to move away from the second mounting seat 401, and no pressing force is generated on the first pressing member 834. The second actuating member 848 is driven by the second driving member 846 to move away from the second mounting seat 401, and no pressing force is generated on the second pressing member 835. The locking member 811 on which the second pressing member 835 does not exert a force moves away from the second mounting seat 401 due to the elastic force of the second reset member 814 and is inserted into the second locking hole 813. Then, the turntable 402 is locked relative to the second mounting seat 401. That is, the turntable 402 and the seat body 1 attached to the turntable 402 are locked in the rearward use mode.

[0087] The above embodiment is merely an example, and the fourth locking mechanism 800 may be in other forms as long as the locking and unlocking between the turntable 402 and the second mounting seat 401 can be realized.

[0088] The above child safety seat and seat base 2 have at least the following technical effects.

[0089] Currently, most commercially available child safety seats prevent infants from using the child safety seat forward by artificial mechanical means. Such misuse prevention mechanisms have a relatively complex structure and high manufacturing costs, and also rely heavily on human factors. If the safety awareness of the caregiver is not strong, it is difficult to play the role of misuse prevention. In the seat base 2 for a child safety seat of the present invention, the turntable 402 is rotatably arranged on the second mounting seat 401, and the second control module 50 receives the child attribute and position information of the turntable 402 detected by the fifth detection device 400, for example, whether the turntable 402 is in the first rotation position or the second rotation position (the first rotation position and the second rotation position correspond to the forward use mode and the rearward use mode respectively), determines whether the child attribute matches the position information of the turntable 402, outputs a matching signal, and reminds the caregiver whether the turntable 402 is in the correct position, that is, whether the seat body 1 attached to the turntable 402 is in the correct use mode. Thereby, it is possible to prevent an infant from using the child safety seat forward due to the caregiver's carelessness or inappropriate operation, improve the safety performance of the child safety seat, and simplify the structure and facilitate implementation.

[0090] FIG. 45 is a schematic diagram of a safety belt wearing promotion system according to an exemplary embodiment.

[0091] In the embodiment, the safety belt wearing promotion system is applied to a child safety seat, but those skilled in the art will understand that the safety belt wearing promotion system according to the embodiments of the present invention can also be applied to other safety seats such as safety seats for pets and is not limited to this embodiment.

[0092] Referring to FIG. 45, in one embodiment, the seat belt wearing promotion system 11 includes a seat belt detection device 501, a seating detection device 502, and a third control module 503. In some embodiments, the third control module 503 is the same control module as the first control module 120 and / or the second control module 50 of the foregoing embodiments.

[0093] The seat belt detection device 501 is configured to detect whether a seat belt passes through the seat belt path of the child safety seat and transmit a corresponding first signal to the third control module 503. The seating detection device 502 is configured to detect whether an object is seated on the child safety seat and transmit a corresponding second signal to the third control module 503. The third control module 503 is configured to receive the first signal and the second signal. The first signal and the second signal are used to generate a prompt signal. The first signal is generated by the seat belt detection device 501 according to whether the seat belt passes through the seat belt path of the child safety seat. The second signal is generated by the seating detection device 502 according to whether the object is seated on the child safety seat.

[0094] In one embodiment, the first signal includes a seat belt worn signal and a seat belt not worn signal. When the seat belt detection device 501 detects that the seat belt has passed through the seat belt path of the child safety seat, it transmits a seat belt worn signal to the third control module 503. When the seat belt detection device 501 does not detect that the seat belt has passed through the seat belt path of the child safety seat, it transmits a seat belt not worn signal to the third control module 503.

[0095] In one embodiment, the second signal includes a seated signal and an unseated signal. When the seating detection device 502 detects that the object is seated on the child safety seat, the seating detection device 502 transmits the seated signal to the third control module 503. When the seating detection device 502 does not detect that the object is seated on the child safety seat, the seating detection device 502 transmits the unseated signal to the third control module 503, or the seating detection device 502 does not transmit the seated signal to the third control module 503.

[0096] In one embodiment, the third control module 503 is configured to generate a prompt signal when receiving the seated signal and the seat belt non-wearing signal.

[0097] In one embodiment, the third control module 503 alternately transmits the received first signal and the second signal to the terminal device, and the terminal device generates a prompt signal based on the first signal and the second signal. The process by which the terminal device generates a prompt signal based on the first signal and the second signal is the same as the process by which the third control module 503 generates a prompt signal based on the first signal and the second signal. Details will not be described again.

[0098] Referring to FIG. 45, the seat belt detection device 501 is configured to detect whether the seat belt passes through the seat belt path of the child safety seat. When the seat belt detection device 501 detects that the seat belt passes through the seat belt path of the child safety seat, the seat belt detection device 501 transmits a seat belt wearing signal (signal 1) to the third control module 503.

[0099] The seat belt path of the child safety seat refers to the path where the vehicle seat belt is located when the child safety seat is fixed to the vehicle by the vehicle seat belt.

[0100] The seating detection device 502 is configured to detect whether an object is seated on the child safety seat, and when it detects that the object is seated on the child safety seat, it transmits a seating signal (Signal 2) to the third control module 503.

[0101] In this embodiment, the object includes an infant using the child safety seat. However, in other embodiments, the object may further include a pet or the like, but the present invention is not limited thereto.

[0102] The third control module 503 is configured to generate a prompt signal when it receives the seating signal but does not receive the seat belt wearing signal, or the third control module 503 is configured to generate a prompt signal when it receives the seating signal and receives the seat belt non-wearing signal.

[0103] Specifically, when the third control module 503 receives the seating signal but does not receive the seat belt wearing signal, or when the third control module 503 receives the seating signal and receives the seat belt non-wearing signal, it indicates that the object is seated on the child safety seat, but the vehicle seat belt does not fix the child safety seat and the object to the vehicle seat. In this case, the third control module 503 automatically generates a prompt signal to prompt the user to fix the child safety seat using the vehicle seat belt.

[0104] The third control module 503 is configured not to generate a prompt signal when it does not receive the seating signal. Similarly, the third control module 503 does not generate a prompt signal in either case when it receives the seating signal and when it receives the seat belt wearing signal.

[0105] Specifically, when the third control module 503 does not receive a seating signal, it indicates that the object is not seated on the child safety seat. In this case, there is no need to prompt the user to fix the child safety seat using the vehicle's safety belt. When the third control module 503 receives a seating signal and a safety belt wearing signal, it indicates that the object is seated on the child safety seat and the user is using the vehicle's safety belt to fix the child safety seat and the object to the vehicle seat. In this case as well, there is no need to fix the child safety seat using the vehicle's safety belt.

[0106] In the safety belt wearing prompting system according to this embodiment of the present invention, the safety belt detection device detects whether the safety belt passes through the safety belt path of the child safety seat and transmits a corresponding first signal to the third control module. The seating detection device detects whether the object is seated on the child safety seat and transmits a corresponding second signal to the third control module. The third control module receives the first signal and the second signal. The first signal and the second signal are used to generate a prompt signal. The system can automatically generate a prompt signal according to whether the safety belt passes through the safety belt path of the child safety seat and whether the object is sitting on the child safety seat, and prompt the user to fix the child safety seat using the vehicle's safety belt. For example, when the object is seated on the child safety seat but the vehicle's safety belt does not fix the child safety seat and the object to the vehicle seat, or when the vehicle's safety belt does not correctly fix the child safety seat and the object to the vehicle seat, a prompt signal is automatically generated, thereby effectively preventing the child safety seat from being fixed without using the vehicle's safety belt or using it incorrectly due to the user's carelessness, improving the use stability of the child safety seat, and ensuring the safety of the object.

[0107] FIG. 46 is a schematic diagram of a safety belt wearing prompting system according to another embodiment.

[0108] Referring to FIG. 46, in one embodiment, the seat belt wearing promotion system 12 includes a seat belt detection device 501, a seating detection device 502, a third control module 503, a sixth detection device 504, and a support leg detection device 505. Optionally, in some embodiments, the sixth detection device 504 is the same detection device as the third detection device 150 and / or the fifth detection device 400 of the foregoing embodiments.

[0109] Since the related descriptions of the seat belt detection device 501, the seating detection device 502, and the third control module 503 can be obtained by referring to the related descriptions of the embodiment of FIG. 45 above, the details will not be described again here.

[0110] The seat belt path of the child safety seat refers to the path where the vehicle seat belt is located when the child safety seat and the object are fixed by the vehicle seat belt.

[0111] The sixth detection device 502 is configured to detect the usage mode of the child safety seat and send a corresponding third signal to the third control module. The support leg detection device 505 is configured to detect whether the support legs of the child safety seat are folded and send a corresponding fourth signal to the third control module. The third control module is configured to receive the first signal, the second signal, the third signal, and the fourth signal. The first signal, the second signal, the third signal, and the fourth signal are used to generate a prompt signal.

[0112] In one embodiment, the third signal includes a forward use signal and a rearward use signal. The sixth detection device 504 is configured to detect the use mode of the child safety seat. The use mode of the child safety seat includes a forward use mode and a rearward use mode. When the sixth detection device 504 detects that the use mode of the child safety seat is the forward use mode, it transmits the forward use signal (signal 3) to the third control module 503. When the sixth detection device 504 detects that the use mode of the child safety seat is the rearward use mode, it transmits the rearward use signal to the third control module 503 without transmitting the forward use signal to the third control module 503.

[0113] In one embodiment, the fourth signal includes a support leg folding signal. The support leg detection device 505 is configured to detect whether the support legs of the child safety seat are folded, and when the support legs are folded, transmit the support leg folding signal (signal 4) to the third control module 503. The support leg detection device 505 is configured not to transmit the support leg folding signal to the third control module 503 when the support legs are not folded.

[0114] In one embodiment, the third control module 503 alternately transmits the received first signal, second signal, third signal, and fourth signal to the terminal device, and the terminal device generates a prompt signal based on the first signal, second signal, third signal, and fourth signal. The process by which the terminal device generates a prompt signal based on the first signal, second signal, third signal, and fourth signal is the same as the process by which the third control module 503 generates a prompt signal based on the first signal, second signal, third signal, and fourth signal. Details will not be described again here.

[0115] Generally, a child safety seat has three usage modes: a first usage mode, a second usage mode, and a third usage mode. The first usage mode is applicable to older children (e.g., children above the first set age). When using the child safety seat in the forward-facing usage mode, the support legs of the child safety seat need to be folded for use. In the first usage mode, both the child safety seat and the object need to be fixed to the vehicle seat via a safety belt.

[0116] The second usage mode is applicable to older children (e.g., children above the second set age and below the first set age). When using the child safety seat in the forward-facing usage mode, the support legs are in a deployed state. The child safety seat is fixed to the vehicle seat via ISOFIX and the support legs. The lower end of the support legs contacts the vehicle floor. The object is restrained within the child safety seat via a five-point safety belt.

[0117] The third usage mode is applicable to younger children (e.g., children below the second set age). When using the child safety seat in the rear-facing usage mode, the support legs are in a deployed state. The child safety seat is fixed to the vehicle seat via ISOFIX and the support legs. The lower end of the support legs contacts the vehicle floor. The object is restrained to the child safety seat by a five-point safety belt.

[0118] When the child safety seat adopts the first usage mode, the third control module 503 receives the seating signal (signal 2), the forward-facing usage signal (signal 3), and the support leg folding signal (signal 4), and generates a prompt signal when it does not receive the safety belt wearing signal (signal 1). Or, the third control module 503 receives the seating signal (signal 2), the forward-facing usage signal (signal 3), and the support leg folding signal (signal 4), and generates a prompt signal when it receives the safety belt non-wearing signal. Specifically, when the third control module 503 receives the seating signal, the forward-facing usage signal, and the support leg folding signal but does not receive the safety belt wearing signal, or when the third control module 503 receives the seating signal, the forward-facing usage signal, and the support leg folding signal and receives the safety belt non-wearing signal, this indicates that the object is seated on the child safety seat, the child safety seat is in the forward-facing usage mode, the support legs are folded, but the vehicle safety belt does not fix the child safety seat and the object to the vehicle seat, or the vehicle safety belt does not correctly fix the child safety seat and the object to the vehicle seat. In this case, the third control module 503 automatically generates a prompt signal to prompt the user to use the vehicle safety belt to fix the child safety seat.

[0119] When the child safety seat adopts the second usage mode or the third usage mode, the support legs are in the deployed state. In this case, the support leg detection device 505 does not send the support leg folding signal to the third control module 503. The third control module 503 is configured not to generate a prompt signal when it does not receive the support leg folding signal.

[0120] Similarly, the third control module 503 is configured not to generate a prompt signal when receiving a seat belt wearing signal. Similarly, the third control module 503 is also configured not to generate a prompt signal when not receiving a seating signal. Similarly, the third control module 503 is configured not to generate a prompt signal when not receiving a seat belt wearing signal, not receiving a seating signal, and not receiving a forward use signal.

[0121] Specifically, when the third control module 503 does not receive a support leg folding signal, it indicates that the use mode of the child safety seat is the second use mode or the third use mode. In this case, the child safety seat realizes a fixed connection with the vehicle via ISOFIX and the support legs, the object is restrained in the child safety seat via a five-point seat belt, and it does not prompt the user to fix the child safety seat using the vehicle seat belt. When the third control module 503 receives a seat belt wearing signal, it indicates that the user has fixed the child safety seat to the vehicle seat using the vehicle seat belt. In this case, there is no need to notify the user to fix the child safety seat using the vehicle seat belt. When the third control module 503 does not receive a seating signal, it indicates that the object is not seated in the child safety seat. In this case as well, there is no need to notify the user to fix the child safety seat using the vehicle seat belt. When the third control module 503 does not receive a seat belt wearing signal, receives a seating signal, and does not receive a forward use signal, it indicates that the object is seated, and the child safety seat adopts a rearward use mode. In this case, the child safety seat realizes a fixed connection with the vehicle via ISOFIX and the support legs, and the object is restrained in the child safety seat via a five-point seat belt. Therefore, there is also no need to notify the user to fix the child safety seat using the vehicle seat belt.

[0122] In the seat belt wearing promotion system according to an embodiment of the present invention, the seat belt detection device detects whether the seat belt passes through the seat belt path of the child safety seat, and when it detects that the seat belt has passed through the seat belt path of the child safety seat, it transmits a seat belt wearing signal to the third control module. The seating detection device detects whether an object is seated on the child safety belt, and when it detects that the object is seated on the child safety belt, it transmits a seating signal to the third control module. The sixth detection device detects the usage mode of the child safety seat, and when it detects that the usage mode of the child safety seat is the forward-facing usage mode, it transmits a forward-facing usage signal to the third control module. The support leg detection device detects whether the support legs of the child safety seat are folded, and when it detects that the support legs are folded, it transmits a support leg folding signal to the third control module. The prompt signal is generated when the third control module receives the seating signal, the forward-facing usage signal, and the support leg folding signal and has not received the seat belt wearing signal, or when the third control module receives the seating signal, the forward-facing usage signal, and the support leg folding signal and has received a seat belt non-wearing signal. This system can automatically generate a prompt signal to prompt the user to use the vehicle seat belt to fix the child safety seat when the object is seated on the child safety seat, the child safety seat is in the forward-facing usage mode, the support legs are folded, but the vehicle seat belt does not fix the child safety seat and the object to the vehicle seat, or when the vehicle seat belt does not correctly fix the child safety seat and the object to the vehicle seat. Thereby, it can effectively prevent the user from fixing the child safety seat without using the vehicle seat belt due to carelessness, improve the usage stability of the child safety seat, and ensure the safety of the object.

[0123] FIG. 47 is a schematic perspective view of a child safety seat equipped with a seat belt wearing promotion system according to an embodiment, and FIG. 48 is a schematic view of a child safety seat fixed to a vehicle seat belt according to an embodiment.

[0124] Referring to FIG. 47, in one embodiment, the child safety seat includes a seat body 1 and a seat base 2. The seat body 1 is rotatably connected to the seat base 2, and the use mode of the seat body 1 can be changed. Specifically, the seat body 1 can be switched between a forward use mode and a rearward use mode. The seat body 1 includes a seat portion 701, a backrest portion 702, and a headrest portion 703.

[0125] In one embodiment, referring to FIGS. 47 and 48, the seat belt detection device is configured to detect whether a seat belt passes through the seat belt path of the child safety seat. The seat belt path includes a joint 704 between the seat portion 701 and the backrest portion 702, and a region between the backrest portion 702 and the headrest portion 703. As a specific example, the seat belt path includes a guide 705 disposed on the backrest portion 702 or the headrest portion 703.

[0126] When the child safety seat according to the embodiment of the present invention adopts the first use mode (for example, the booster use mode), the vehicle seat belt passes between the backrest portion 702 and the headrest portion 703 (for example, the guide 705 disposed at the lower end of the side wing of the headrest portion 703) of the child safety seat, the child sitting on the child safety seat, and the left and right joints (for example, the recess between the side wing of the seat portion 701 and the side wing of the backrest portion 702) between the seat portion 701 and the backrest portion 702 of the child safety seat, and is fixed to the vehicle seat.

[0127] In one embodiment, the guide 705 is disposed on the headrest portion 703 or the backrest portion 702. When the guide 705 is disposed on the headrest portion 703, by adjusting the height of the headrest portion 703, the height of the shoulder portion of the safety belt can be better adapted to children of different heights. When the guide 705 is disposed on the backrest portion 702, the height of the backrest portion 702 can be adjusted up and down and can be better adapted to children of different heights. In one embodiment, the safety belt detection device includes a third photoelectric sensor. The third photoelectric sensor is shown in FIG. 49. One or more third photoelectric sensors may be provided. The third photoelectric sensor is disposed at the joint portion between the seat portion 701 and the backrest portion 702 (for example, the recess 704 between the side wings of the seat portion 701 and the side wings of the backrest portion 702). The safety belt detection device is configured such that when the third photoelectric sensor detects that the safety belt has passed, it transmits a safety belt wearing signal to the third control module.

[0128] In one embodiment, the safety belt detection device includes a third photoelectric sensor and a fourth photoelectric sensor. The third photoelectric sensor and the fourth photoelectric sensor are shown in FIG. 49. One or more third photoelectric sensors may be provided, and one or more fourth photoelectric sensors may be provided. The third photoelectric sensor is disposed at the joint portion between the seat portion 701 and the backrest portion 702 (for example, the recess 704 between the side wings of the seat portion 701 and the side wings of the backrest portion 702). The fourth photoelectric sensor is disposed on the backrest portion 702 or the headrest portion 703 (for example, the fourth photoelectric sensor is disposed on the guide 705 at the lower end of the side wing of the headrest portion 703). For example, two third photoelectric sensors are provided, each disposed at the joint portion between the left and right sides of the backrest portion 702 and the seat portion 1. Two fourth photoelectric sensors are provided, each disposed on the guide 705 at the lower ends of the left and right side wings of the headrest portion 703.

[0129] In one embodiment, the seat belt detection device is configured to transmit a seat belt wearing signal to the third control module when both the third photoelectric sensor and the fourth photoelectric sensor detect the passage of the seat belt. When a plurality of third photoelectric sensors and a plurality of fourth photoelectric sensors are provided, when two third photoelectric sensors and one fourth photoelectric sensor detect the passage of the seat belt, the seat belt wearing signal is transmitted to the third control module. Taking the child safety seat fixed by the vehicle seat belt shown in FIG. 48 as an example, when the child safety seat is fixed to the vehicle seat using the vehicle seat belt, the path where the vehicle seat belt is located includes the left joint 704 and the right joint 704 between the seat part 701 and the backrest part 702, and the guide 705 arranged at the lower end of the left wing of the headrest part 703. When two third photoelectric sensors and one fourth photoelectric sensor of the seat belt detection device detect that the seat belt has passed, a seat belt wearing signal is transmitted to the third control module.

[0130] In another embodiment of the present invention, the seat belt detection device includes only two third photoelectric sensors respectively arranged at the left joint 704 and the right joint 704 between the seat part 701 and the backrest part 702. When both of the two third photoelectric sensors detect that the seat belt has passed, the seat belt detection device transmits a seat belt wearing signal to the third control module.

[0131] In an exemplary embodiment, referring to FIG. 47, the seating detection device 706 includes a pressure sensor 7061, and the seating detection device 706 is arranged on the seat body 1 of the child safety seat, for example, on the cushion of the seat part 701 of the seat body 1. The pressure sensor 7061 detects whether an object is seated by detecting the pressure applied to the seat part 701. For example, when the pressure applied to the seat part 701 is greater than a preset threshold value, it is considered that an object is seated.

[0132] In an exemplary embodiment, referring to FIG. 47, the child safety seat further includes a seat base 2. A sixth detection device is disposed between the seat body 1 and the seat base 2 of the child safety seat to facilitate detection of whether the use mode of the child safety seat is a forward use mode or a rearward use mode.

[0133] FIG. 50 is a perspective view of a child safety seat adopting a rearward use mode according to an embodiment.

[0134] Referring to FIG. 50, when the child safety seat adopts a rearward use mode, the child safety seat realizes connection and fixation via ISOFIX and the support legs 308, and the child is restrained within the child safety seat via a five-point safety belt on the child safety seat. In this case, the support legs 308 are in a deployed state, and the support legs 308 and the seat base 2 are arranged at an angle. For example, the support legs 308 and the seat base 2 are perpendicular to each other.

[0135] When the child safety seat adopts a forward use mode and it is necessary to fix the child safety seat and the object to the vehicle seat via the vehicle safety belt, the support legs 308 are in a folded state with respect to the seat base 2, and the support legs 308 are hidden under the bottom surface of the seat base 2, which is advantageous for stably arranging the seat base 2 of the child safety seat on the vehicle seat.

[0136] FIG. 51 is a perspective view of a child safety seat provided with a support leg detection device according to an embodiment.

[0137] In an exemplary embodiment, referring to FIG. 51, the support leg detection device 505 is disposed at the bottom of the child safety seat to facilitate detection of whether the support legs 308 are in a folded state.

[0138] Figures 54 and 56 are perspective views showing a support leg detection device for a child safety seat according to an embodiment of the present invention. To facilitate the display of the detection sheet 1102 and the third sensor 1103 inside the seat base 2 of the child safety seat, FIG. 54 shows the state where the bottom housing of the seat base 2 of the child safety seat is removed, and FIG. 55 shows an enlarged view of part X in FIG. 54.

[0139] Referring to FIGS. 54, 55, and 56 together, the support leg detection device 505 includes a detection switch 1101, a detection sheet 1102, and a third sensor 1103 (for example, a photoelectric sensor) disposed around or behind the detection sheet 1102. The detection sheet 1102 and the third sensor 1103 are disposed within the seat base 2. The detection switch 1101 is disposed at the bottom of the seat base 2.

[0140] In one embodiment, the detection switch 1101 is slidably connected to the bottom of the seat base 2. After the support leg 308 is folded, the detection switch 1101 is pushed into the seat base 2, and the detection sheet 1102 is driven to extend into the sensing range of the third sensor 1103. The third sensor 1103 transmits a support leg folding signal notifying that the support leg 308 has been folded to the third control module 503.

[0141] FIG. 52 is a schematic diagram of a safety belt wearing promotion system according to an exemplary embodiment.

[0142] Referring to FIG. 52, in one embodiment, the seat belt wearing promotion system 13 includes a seat belt detection device 501, a seating detection device 502, a third control module 503, a sixth detection device 504, a support leg detection device 505, and a third display device 506. In some embodiments, the third display device 506 is the same display device as the first display device 130 and / or the second display device 60 of the foregoing embodiments. The related descriptions of the seat belt detection device 501, the seating detection device 502, the third control module 503, the sixth detection device 504, and the support leg detection device 505 can be obtained by referring to the related descriptions of the embodiment of FIG. 45 and Embodiment 2 above. Details will not be described again here.

[0143] In one embodiment, the third display device 506 is configured to receive a prompt signal and transmit prompt information based on the prompt signal. The third display device 506 is a light emitter or a buzzer, and the prompt information is light information or sound information.

[0144] For example, after receiving the prompt signal, the third display device 506 emits light of a preset color to prompt the user to fix the child safety seat using the vehicle seat belt. Alternatively, after receiving the prompt signal, the third display device 506 emits a preset sound (e.g., an alarm sound) to prompt the user to fix the child safety seat using the vehicle seat belt.

[0145] In an exemplary embodiment, the seat belt detection device 501 is configured to detect that the seat belt has passed through the seat belt path of the child safety seat, and the seat belt detection device 501 transmits a seat belt wearing signal to the third control module 503. The third control module 503 is further configured to generate a prompt stop signal when receiving the seat belt wearing signal. The prompt stop signal is used to instruct the third display device 506 to stop transmitting prompt information.

[0146] In one embodiment, the third display device 506 is configured to receive a prompt stop signal and transmit prompt information based on the prompt stop signal.

[0147] For example, after receiving the prompt stop signal, the third display device 506 stops emitting light of a preset color. Alternatively, after receiving the prompt stop signal, the third display device 506 stops emitting a preset sound (e.g., an alarm sound).

[0148] In one embodiment, when the seat belt detection device 501 detects that the seat belt has passed through the seat belt path of the child safety seat, it transmits a seat belt wearing signal to the third control module 503. When receiving the seat belt wearing signal, the third control module 503 generates a prompt stop signal and transmits the prompt stop signal to the third display device 506. After receiving the prompt stop signal, the third display device 506 stops transmitting prompt information based on the prompt stop signal. According to this method, after the user fixes the child safety seat using the vehicle seat belt, the transmission of prompt information can be stopped in a timely manner.

[0149] In an exemplary embodiment, the third control module 503 alternatively transmits the above prompt signal to the terminal device via a wireless network, and the terminal device displays prompt information based on the prompt signal. For example, the terminal device displays the prompt information on the screen of the terminal device and prompts the user to fix the child safety seat using the vehicle seat belt.

[0150] In an exemplary embodiment, the third control module 503 directly transmits the signals sent from the seat belt detection device 501, the seating detection device 502, the sixth detection device 504, and the support leg detection device 505 to the terminal device via a wireless network, and the terminal device makes a determination. When the terminal device receives a seating signal, a forward use signal, and a support leg folding signal but does not receive a seat belt wearing signal, the terminal device directly generates prompt information and displays the prompt information on the screen of the terminal device to prompt the user to fix the child safety seat using the vehicle seat belt.

[0151] In an exemplary embodiment, the third control module 503 alternatively transmits the above-mentioned prompt stop signal to the terminal device via a wireless network, and the terminal device stops displaying the prompt information based on the prompt stop signal.
