[0045] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.

[0046] In one embodiment, Figure 1 As shown, an anti-misuse system 200 is provided, which is applicable to a child safety seat 100. The anti-misuse system 200 includes a detection device 210 and a reminder device 220. The detection device 210 is coupled to the reminder device 220, and the coupling includes a wired or wireless communication connection or signal exchange.

[0047] The child safety seat 100 includes a base 110 and a seat body 120 arranged on the base 110; the seat body 120 has a forward use mode and a rearward use mode; the seat body 120 switches between the forward use mode and the rearward use mode by rotating relative to the base 110; the detection device 210 is configured to detect whether the current use mode of the seat body 120 is the forward use mode or the rearward use mode; the reminder device 220 is configured to perform a reminder operation according to the current use mode detected by the detection device 120.

[0048] Specifically, refer to Figure 2 The child safety seat 100 of one embodiment shown in the figure comprises a base 110 and a seat body 120, wherein the seat body 120 is disposed above the base 110. Figure 3A and Figure 3B , respectively showing the forward use mode and the rearward use mode of the seat body 120. Figure 3A In the forward-facing mode of use shown, the seat body 120 faces the front of the vehicle (to the left); Figure 3BIn the rearward use mode shown, the seat body 120 faces the rear of the vehicle (toward the right). The seat body 120 is arranged to be rotatable relative to the base 110. The user can switch between the forward use mode and the rearward use mode by operating the seat body 120 to rotate relative to the base 110.

[0049] The detection device 210 can be used to detect whether the current use mode of the seat body 120 is the forward use mode or the rearward use mode. In practical applications, the detection device 210 can be arranged in the child safety seat 100. Of course, those skilled in the art can set the specific position of the detection device 210 according to actual needs to effectively detect the current use mode of the seat body 120.

[0050] The detection device 210 can be connected to the reminder device 220 for communication, and when the current use mode of the seat body 120 is detected, the detection device 210 sends a corresponding detection signal to the reminder device 220 .

[0051] The reminder device 220 can perform corresponding reminder operations according to the detection signal to remind the user of the content related to the current use mode of the seat body 120. Those skilled in the art can set the specific position of the detection device 210 according to actual needs to effectively remind the user according to the detection signal of the detection device 210.

[0052] After the user senses the reminder, the user can adjust the usage mode of the seat body 120 according to the content of the reminder to adapt to the relevant attributes (age, height, weight, etc.) of the child currently carried by the child safety seat.

[0053] For example, the user can place the infant on the child safety seat in the car and adjust the orientation of the seat body 120 to a certain usage mode. At this time, the detection device 210 detects that the seat body 120 is in the forward usage mode. The detection device 210 can send a corresponding signal to the reminder device 220. The reminder device 220 can remind the user by voice that the seat is in the forward usage mode, and the weight of the infant using the child safety seat is 10KG. The user thus finds that the current usage mode is not suitable for the infant, so the seat body 120 can be turned back to the rearward usage mode; or, if the user presets the weight of the young child to be 10KG, the reminder device 220 can remind the user that the seat is in the forward usage mode, which is not suitable for the current user. After receiving the reminder, the user can readjust the orientation of the seat body 120 to the rearward usage mode.

[0054] The above-mentioned anti-misuse system detects the current usage mode of the seat body through a detection device, and then reminds the user of information related to the current usage mode through a reminder device, so that the user can adjust the child safety seat to a usage mode suitable for the user according to the information, thereby avoiding users from misusing the usage mode of the child safety seat and improving the safety of children riding in a vehicle.

[0055] In one embodiment, the anti-misuse system 200 further includes a controller 230;

[0056] The controller 230 is configured to determine whether the current use mode is the forward use mode or the backward use mode according to the detection signal of the detection device;

[0057] The reminder operation includes at least one of the following: current mode reminder, attribute adaptation reminder, mode mismatch reminder, attribute reset reminder and direction abnormality reminder.

[0058] A current mode reminder, used to remind the child safety seat is currently in a forward-facing use mode or a rearward-facing use mode;

[0059] An adaptation attribute reminder, used to remind the child's attributes that are compatible with the current use mode of the child safety seat;

[0060] A mode mismatch reminder, used to remind that the current use mode of the child safety seat is incompatible with the child attributes of the child;

[0061] An attribute reset reminder, used to remind the child to reset the child's attributes;

[0062] The abnormal orientation reminder is used to remind that the orientation of the child safety seat does not conform to the forward use mode or the rearward use mode.

[0063] Specifically, the controller 230 may be disposed in the base 110 or in the seat body 120. The controller 230 may be connected to the detection device 210 by communication via a communication module. The communication module may be a wired communication module or a wireless communication module.

[0064] The controller 230 may receive the detection signal sent by the detection device 210 through the communication module, and the controller 230 may determine whether the current use mode of the seat body 120 is the forward use mode or the rearward use mode according to the detection signal.

[0065] The child attributes may specifically include at least one of age, weight and height.

[0066] The current use mode may have corresponding child attributes. For example, the child attributes corresponding to the forward use mode may be age over 15 months, weight over 18 kg, and / or over 76 cm; and the child attributes corresponding to the backward use mode may be age under 15 months, weight under 18 kg, and / or under 76 cm.

[0067] Specifically, the current mode reminder can be used to remind the user that the seat body 120 is currently in the forward use mode or the rearward use mode. The user can use the reminder to determine whether the current use mode is suitable for the user. If the user finds that the current use mode is not suitable for the user, the seat body 120 can be rotated to rotate the seat body 120 to a suitable use mode.

[0068] The adaptive attribute reminder can be used to remind the child attributes that are compatible with the current usage mode. The user can know the child attributes corresponding to the current usage mode and determine whether the child attributes are compatible with the child attributes of the currently carried child. If the user finds that it is not compatible, the seat body 120 can be rotated to rotate the seat body 120 to an adaptive usage mode.

[0069] The mode mismatch reminder can be used to remind the user that the current use mode is incompatible with the child attributes of the currently carried child. The anti-misuse system 200 can be provided with an input device for the user to input the child attributes such as the age, weight and height of the user, or the anti-misuse system 200 can be provided with an attribute detection device to automatically detect the child attributes such as the age, weight and height of the current child, so as to obtain the child attributes of the child carried by the child safety seat. Then, the two child attributes can be compared, and when it is determined that the two child attributes do not match, the above-mentioned mode mismatch reminder is executed to remind the user to turn the seat body 120 to an adapted use mode.

[0070] When the child carried by the child safety seat 100 is changed, the pre-acquired child attributes may be inaccurate. Therefore, the attribute reset reminder can be used to remind the user to reset the child attributes according to the currently carried child.

[0071] When the user operates the seat body 120 to rotate, the seat body 120 may not be completely rotated to the correct angle to achieve the forward use mode or the rearward use mode. For example, the seat body 120 after rotation is not completely facing the front or the rear. Therefore, the user can be reminded through an abnormal direction reminder that the direction of the seat body 120 does not conform to the forward use mode and the rearward use mode. After receiving the reminder, the user can continue to rotate the seat body 120 to a certain angle to rotate to the correct forward use mode or the rearward use mode.

[0072] The above-mentioned anti-misuse system, through the reminder device, executes reminder operations such as current mode reminder, adaptation attribute reminder, mode incompatibility reminder, attribute reset reminder and orientation abnormality reminder, effectively preventing users from misusing the use mode of child safety seats and improving the safety of children riding in vehicles.

[0073] In one embodiment, the reminder device 220 includes a reminder provided on the seat body 120 and / or the base 110; the controller 230 is configured to trigger the reminder to execute a current mode reminder and / or an adaptation attribute reminder according to the current usage mode of the child safety seat 100, and / or to match the attributes of the young child with the attributes of the young child that are adapted to the current usage mode, and to trigger the reminder to execute a mode mismatch reminder and / or an attribute reset reminder when there is a mismatch, and / or to determine that the orientation of the child safety seat 100 is abnormal according to the detection signal of the detection device 210, and to trigger the reminder to execute an abnormal orientation reminder.

[0074] Specifically, the reminder device 220 may include one or more reminders, which may be arranged on the seat body 120 , or on the base 110 , or may be arranged on both the seat body 120 and the base 110 .

[0075] After determining the current usage mode of the seat body 120 according to the detection signal of the detection device 210, the controller 230 may send a corresponding signal to the reminder to trigger the reminder to execute the current mode reminder and / or the adaptation attribute reminder.

[0076] The controller 230 may also match the child attributes of the child currently carried by the child safety seat 100 with the child attributes corresponding to the current use mode, and trigger a trigger to provide a mode mismatch reminder and / or an attribute reset reminder when there is a mismatch.

[0077] The controller 230 may also send a corresponding signal to the reminder after determining that there is an abnormality in the orientation of the seat body 120 according to the detection signal, so as to trigger the reminder to perform an abnormal orientation reminder.

[0078] The above-mentioned anti-misuse system, by providing a reminder on the seat body and / or the base, can enable the user to receive reminder information in a timely manner, effectively avoid the user's misuse of the child safety seat, and improve the safety of children riding in the vehicle.

[0079] In one embodiment, the reminder device 220 includes an external terminal device that is communicatively connected to the controller 230; the controller 230 is configured to transmit information indicating the current usage mode to the external terminal device; and / or, determine the orientation abnormality of the seat body 120 based on the detection signal of the detection device 210, and send the orientation abnormality information to the external terminal device; the external terminal device is configured to execute a current mode reminder and / or an adaptation attribute reminder according to the current usage mode, and / or, match the child attributes of the child currently carried by the child safety seat with the child attributes adapted to the current usage mode, and execute a mode mismatch reminder and / or an attribute reset reminder when there is a mismatch, and / or, execute a seat body orientation abnormality reminder based on the orientation abnormality information.

[0080] Specifically, the controller 230 can communicate remotely with one or more external terminal devices through the communication module, wherein the external terminal device can be a terminal such as a mobile phone, a tablet computer, a laptop computer, etc.

[0081] After determining the current use mode of the seat body 120 according to the detection signal of the detection device 210, the controller 230 may transmit information indicating the current use mode to one or more external terminal devices. The controller 230 may also send corresponding abnormal orientation information to one or more external terminal devices when determining that the orientation of the seat body 120 is abnormal according to the detection signal of the detection device 210.

[0082] The above-mentioned anti-misuse system utilizes the remote communication function and multimedia playback function of the external terminal device itself to communicate remotely with the controller and perform various reminder operations. There is no need to deploy hardware for executing reminders on the child safety seat, which reduces the cost of the child safety seat. At the same time, it allows users to receive reminder information in a timely manner, effectively avoiding users' misuse of the child safety seat and improving the safety of children riding in a vehicle.

[0083] In one embodiment, the reminder device 220 is configured to perform at least one of playing a reminder voice, displaying a reminder text, displaying a reminder image, and playing a reminder video.

[0084] Specifically, the reminder device 220 may include a reminder device provided on the seat body 120 and / or the base 110, and / or an external terminal device connected to the controller 230. It is understood that the external terminal device may perform reminder operations such as playing reminder voice, displaying reminder text, displaying reminder image, playing reminder video, etc. in the form of voice, text, image, video, etc. In addition, the reminder device may also perform reminder operations in the form of voice, text, image, video, etc. For example, the reminder device may have a display screen, which is used to play reminder text, reminder image, reminder video, etc. The reminder device may also have a speaker for playing reminder voice.

[0085] The above-mentioned anti-misuse system and reminder device can remind users in a flexible manner to ensure that users receive reminder information in a timely and effective manner, effectively avoid users from misusing child safety seats, and improve the safety of children riding in vehicles.

[0086] In one embodiment, the anti-misuse system 200 further includes an external terminal device and / or an input device provided on the child safety seat; the external terminal device and / or the input device are configured for a user to input child attributes; the child attributes are used to perform a reminder operation.

[0087] Specifically, an input device may be provided on the base 110 or the seat body 120 for the user to input the child's attributes such as age, weight, height, etc. when using the child safety seat for the first time.

[0088] For example, the input device may have a display screen with a touch function, and the user may input attributes such as age, weight, height, etc. on the display screen. For another example, the input device may have a display screen and physical buttons, and the user may input the attributes of the current object of use by cooperating with the display screen and the physical buttons. In addition, the user may also use the information input function of the external terminal device itself to input the attributes of the current object of use. The external terminal device may store the attributes of the current object of use input by the user to perform a reminder operation based on the attributes of the young child.

[0089] The above-mentioned anti-misuse system provides a flexible information input method, so that the user can easily input the attributes of the child, so as to achieve more accurate reminders, thereby effectively preventing the user from misusing the child safety seat, and improving the safety of children riding. For example, the user can enter the child's date of birth, and the system will automatically calculate the child's current age, so that the controller 230 controls the safety seat to be forced to be configured backward or allows it to be configured forward.

[0090] In one embodiment, the child safety seat 100 includes a detection point; the detection device 210 includes a sensor; one of the sensor and the detection point is disposed on the seat body 120, and the other of the sensor and the detection point is disposed on the base 110; the sensor or the detection point disposed on the seat body 120 rotates with the seat body 120; when the seat body 120 rotates to the forward use mode or the rearward use mode, the detection point triggers the sensor to generate a detection signal to determine that the current use mode is the forward use mode or the rearward use mode.

[0091] Specifically, a sensor may be provided on the seat body 120 and a detection point may be provided on the base 110, or a sensor may be provided on the base 110 and a detection point may be provided on the seat body 120. During the rotation of the seat body 120, the sensor or detection point provided on the seat body 120 rotates with the seat body 120, and correspondingly, the detection point or sensor provided on the base 110 remains fixed. When the seat body 120 rotates relative to the base 110 to a forward use mode or a rearward use mode, the detection point provided on the seat body 120 or the base 110 will trigger the sensor to generate a corresponding detection signal.

[0092] Among them, the detection point can trigger the sensor to generate a detection signal in a non-contact manner. For example, the sensor can be an infrared sensor, and the detection point can be a light-transmitting gap. When the infrared sensor is aligned with the gap, the infrared sensor is triggered to generate a detection signal. The detection point can also trigger the sensor to generate a detection signal in a contact manner. For example, the sensor can be a mechanical switch sensor with a switch lever, and the detection point can be a protrusion for the wave lever. When the protrusion toggles the switch lever of the mechanical switch sensor, the mechanical switch sensor is triggered to generate a detection signal. Of course, those skilled in the art can also use other specific matching methods of the detection point and the sensor to realize the detection of the current use mode. The embodiments of the present application do not limit the specific forms of the detection point and the sensor.

[0093] The above-mentioned anti-misuse system has one of the sensor and the detection point arranged on the seat body and the other of the sensor and the detection point arranged on the base, and utilizes the rotation of the seat body relative to the base to make the detection point trigger the sensor to generate a detection signal, so as to realize the detection of the current usage mode, so that the system architecture is simple and the implementation cost is low.

[0094] In one embodiment, a rotating body 130 is provided at the bottom of the seat body 120; a rotating frame 131 is provided on the rotating body 130; the rotating frame 131 rotates with the rotating body 130; the detection point is provided on the rotating frame 131, and the sensor is provided on the base 110.

[0095] Specifically, refer to Figure 1 and Figure 4 The rotating body 130 is disposed at the bottom of the seat body 120, that is, between the seat body 120 and the base 110. The rotating body 130 can rotate with the seat body 120 relative to the base 110. The rotating body 130 is provided with a rotating frame 131. During the rotation of the seat body 120, the rotating frame 131 rotates with the rotating body 130.

[0096] The rotating frame 131 may be made of metal, such as steel, but those skilled in the art may use other materials, such as hard plastic.

[0097] At least one sensor may be provided on the base 110 for sending a detection signal when a detection point is detected. More specifically, when the seat body 120 rotates relative to the base 110, the detection point also rotates accordingly, and when the seat body 120 is turned to a forward use mode or a rearward use mode, the detection point also rotates to a position detectable by the sensor, thereby triggering the sensor to generate a detection signal.

[0098] In one embodiment, reference Figure 4 and Figure 5 , the sensor includes an infrared sensor; the detection point includes a notch provided on the rotating frame 131; when the notch is within the sensing range of the infrared sensor, the infrared sensor is triggered to generate the detection signal. The infrared sensor may include a transmitter and a receiver, the transmitter is used to emit infrared light, and the receiver is used to trigger the generation of a detection signal when the infrared light is received. The notch is used for the infrared light emitted by the transmitter to pass through and reach the receiver. It can be understood that during the rotation of the seat body 120, when it is not rotated to the forward use mode or the rearward use mode, the position outside the notch of the rotating frame 131 will block the infrared light emitted by the transmitter, so that the receiver will not receive the infrared light. When the seat body 120 is rotated to the forward use mode or the rearward use mode, the infrared sensor is aligned with the notch of the rotating frame 131, so that the infrared light passes through the notch and reaches the receiver, and triggers the generation of a detection signal. The detection is performed in a contactless manner. Since there is no physical contact, it is not easy to be hit and cause damage to the sensor.

[0099] In one embodiment, Figures 4 to 6BAs shown, the infrared sensor includes a first infrared sensor 211 and a second infrared sensor 212; the notch includes a first notch 1311 and a second notch 1312; the first notch 1311 triggers the first infrared sensor 211 to generate the detection signal when the seat body 120 rotates to one of the forward use mode and the rearward use mode; the second notch 1312 triggers the second infrared sensor 212 to generate the detection signal when the seat body 120 rotates to the other of the forward use mode and the rearward use mode.

[0100] Specifically, the first notch 1311 and the second notch 1312 can be disposed on the same side of the central axis a of the rotating frame 131 and facing each other, and the first infrared sensor 211 and the second infrared sensor 212 can be disposed on the frame on the same side of the rotating frame 131. Regardless of whether the seat body 120 is rotated to the forward use mode or the rearward use mode, the rotating frame 131 that rotates accordingly can align the first notch 1311 with the first infrared sensor 211 or align the second notch 1312 with the second infrared sensor 212.

[0101] For example, when the seat body 120 is rotated to the forward use mode, the first notch 1311 and the second notch 1312 are both located on the right side of the central axis a (eg, Fig. 6A As shown), at this time, the second notch 1312 is aligned with the second infrared sensor 212, thereby triggering the second infrared sensor 212 to generate a detection signal (refer to Figure 4 ); When the seat body 120 is rotated to the rearward use mode, the first notch 1311 and the second notch 1312 are both located on the left side of the central axis a (eg Figure 6B As shown). It can be understood that after the rotating frame 131 rotates 180°, the first notch 1311 is aligned with the first infrared sensor 211, thereby triggering the first infrared sensor 211 to generate a detection signal.

[0102] The above-mentioned anti-misuse system is configured with a first infrared sensor, a second infrared sensor, a first notch and a second notch, so that when the seat body is in one of the forward use mode and the rearward use mode, the first notch triggers the first infrared sensor to generate a detection signal, and when the seat body is in the other of the forward use mode and the rearward use mode, the second notch triggers the second infrared sensor to generate a detection signal, thereby realizing the detection of the current use mode through a simple physical structure, with low implementation cost and high detection accuracy.

[0103] In one embodiment, Figure 7As shown, the rotating frame 131 is provided with an additional frame 132, and the additional frame 132 is used to set a plurality of the gaps. The additional frame may be annular. By setting a plurality of gaps on the additional frame for the infrared sensor to detect, the detection accuracy can be improved.

[0104] In one embodiment, the sensor includes a mechanical switch sensor, and the detection point includes a trigger portion provided on the rotating frame 131; the trigger portion is used to trigger the mechanical switch sensor to switch the switch state to generate the detection signal. The mechanical switch sensor has a switch lever; the trigger portion includes a protrusion for toggling the lever. By detecting in a physical contact manner, the current use mode can be stably detected.

[0105] In one embodiment, the controller 230 is configured to determine that the current usage mode is one of the forward usage mode and the backward usage mode when the detection point triggers the sensor to generate a detection signal, and to determine that the current usage mode is the other of the forward usage mode and the backward usage mode when the detection point does not trigger the sensor to generate a detection signal.

[0106] Specifically, only a single detection point and a single sensor may be provided, and the use mode corresponding to the detection signal generated by the sensor may be preset as the forward use mode or the rearward use mode. Thus, when the detection point triggers the sensor to generate a detection signal, it can be determined that the current use mode of the seat body 120 is one of the forward use mode and the rearward use mode, and when the detection point does not trigger the sensor to generate a detection signal, it can be determined that the seat body 120 is the other of the forward use mode and the rearward use mode. Thus, the hardware structure can be simplified through the software method, and the implementation cost is low.

[0107] It should be noted that, although the above embodiment is described by taking the example that the sensor is arranged on the base 110 and the detection point is arranged on the seat body 120, those skilled in the art can understand that based on the characteristic that the seat body 120 rotates relative to the base 110, the above embodiment can also be expanded to a solution in which the detection point is arranged on the base 110 and the sensor is arranged on the seat body 120.

[0108] In one embodiment, Figure 8 As shown, a child safety seat control system 300 is provided, which is applicable to the child safety seat 100, and the child safety seat control system includes: a controller 230 and a driving device 240;

[0109] The child safety seat 100 comprises a base 110 and a seat body 120 disposed on the base 110; the seat body has a use mode; the use mode comprises a forward use mode and a rearward use mode; the seat body 120 switches between the forward use mode and the rearward use mode by rotating relative to the base 110;

[0110] The controller 230 is configured to issue a control instruction; the control instruction is used to indicate a target usage mode; the target usage mode is as described;

[0111] The driving device 240 is coupled to the controller 230 and is configured to drive the seat body 120 of the child safety seat 100 to rotate relative to the base 110 of the child safety seat 100 according to the control instruction of the controller 230 to adjust to a forward use mode or a rearward use mode.

[0112] Specifically, the controller 230 is coupled and communicatively connected to the drive device 240. The controller 230 may be pre-set with child attributes, and transmit corresponding control instructions to the drive device 240 according to the child attributes. For example, the user may pre-set the weight of the infant to 15KG in the controller 230, and the controller 230 may transmit a control instruction to the drive device 240 to adjust to the rearward use mode.

[0113] The driving device 240 can drive the seat body 120 to rotate relative to the base 110 according to the control instruction until the seat body 120 switches to a use mode adapted to the attributes of the young child. For example, when the seat body 120 is in the forward use mode and receives a control instruction indicating that the use mode is adjusted to the rearward use mode, the driving device 240 drives the seat body 120 to rotate until the seat body 120 switches to the rearward use mode. Thus, the seat body can be automatically adjusted to the correct use mode without manual operation by the user, thereby avoiding the user from misusing the use mode of the child safety seat and improving the safety of children riding in the vehicle.

[0114] In one embodiment, reference FIG. 9A to FIG. 9G The driving device 240 includes a transmission mechanism 241 and a motor 242; the motor 242 is configured to drive the transmission mechanism 241 to drive the seat body 120 to rotate. The transmission mechanism 241 includes a worm wheel 2411 disposed at the bottom of the seat body 120 and a worm 2412 disposed in the base 110. The motor 242 is disposed in the base 110 and drives the worm 2412 to rotate; when the worm 2412 rotates, it drives the worm wheel 2411 to rotate; when the worm wheel 2411 rotates, it drives the seat body 120 to rotate.

[0115] Specifically, a worm wheel 2411 can be provided at the bottom side edge of the seat body 120, and a motor 242 connected to a worm 2412 can be provided in the base 110, and the worm 2412 can be driven to rotate by the motor 242 to drive the worm wheel 2411 to rotate, thereby driving the seat body 120 to rotate, so as to adjust to the forward use mode or the backward use mode. The motor 242 can be controlled by the controller 230. When the worm 2412 rotates, the worm wheel 2411 is driven to rotate, and when the worm wheel 2411 rotates, the seat body 120 is driven to rotate, and the structure is relatively simple and the implementation cost is low.

[0116] In addition to the above-mentioned worm gear mechanism, the transmission mechanism 241 can also be implemented as a bevel gear mechanism, a rack and pinion mechanism, a belt drive mechanism or a sprocket chain mechanism, etc., and a first transmission connector and a motor connected to a second transmission connector can be set at the center of the bottom of the seat body 120 to realize transmission.

[0117] In one embodiment, the child safety seat control system 300 further includes an input device provided on the child safety seat 100; the controller 230 stores attributes of young children corresponding to different usage modes; the input device is configured to allow a user to input attributes of the young child carried by the child safety seat 100, and transmit the input attributes of the young child to the controller 230; the controller 230 is configured to determine the usage mode to be adjusted based on the input attributes of the young child.

[0118] In one embodiment, the child safety seat control system 300 also includes a communication module, which is coupled to the controller 230 and communicates with an external terminal device so that the controller 230 sends control instructions to the drive device 240 according to the operation of the external terminal device; the external terminal device stores the child attributes corresponding to different usage modes.

[0119] The external terminal device may also be configured to allow the user to input and store child attributes, so that the usage mode to be adjusted can be determined based on the input child attributes and the controller 230 can be notified so that the controller 230 can issue corresponding control instructions to the drive device 240 .

[0120] The specific method of inputting through the input device and / or the external terminal device has been described in detail in the above embodiments and will not be repeated here. The user can input the child's age, weight, height and other child attributes through the input device and / or the external terminal device. The controller 230 and / or the external terminal device can store the child attributes corresponding to the use mode. Therefore, after obtaining the child attributes input by the user, the use mode to be adjusted can be determined according to the child attributes, so that the seat body 120 can be accurately adjusted to the adapted use mode.

[0121] In one embodiment, the child safety seat control system 300 further includes a detection device 210; the detection device 210 is configured to detect whether the current use mode of the seat body 120 is the forward use mode or the rearward use mode, and transmit information indicating the current use mode to the controller 230; the controller 230 is configured to issue a control instruction to the drive device 240 when the current use mode does not conform to the use mode to be adjusted. The current use mode of the seat body 120 can be detected by the detection device 210, and the detection device 210 can transmit information indicating the current use mode to the controller 230, so that the controller 230 can determine whether the seat body 120 has been rotated to the use mode to be adjusted. When the controller 230 determines that the seat body 120 has not been rotated to the use mode to be adjusted, it can correspondingly instruct the drive device 240 to drive the seat body 120 to rotate until the seat body 120 is rotated to the use mode to be adjusted. Since the specific structure of the detection device 210 has been described in detail in the above embodiment, it will not be repeated here.

[0122] In one embodiment, the child safety seat control system 300 further includes a reminder device 220; the reminder device 220 is configured to perform a reminder operation according to the current use mode detected by the detection device 210. Since the relevant contents of the reminder device 220 have been described in detail in the above embodiments, they will not be repeated here.

[0123] In one embodiment, the child safety seat control system 300 further includes a limiting device 250 ; the limiting device 250 is configured to lock or unlock the seat body 120 according to the current use mode.

[0124] Specifically, the anti-misuse system 200 in the embodiment of the present application limits the rotation of the seat body 120 through the limit device 250. The detection device 210 can detect the current use mode of the seat body 120. When it is determined that the current use mode of the seat body 120 is the correct use mode (i.e., the above-mentioned use mode to be adjusted), the limit device 250 can lock the current use mode of the seat body 120. When it is determined that the current use mode of the seat body 120 is an incorrect use mode, the limit device 250 can release the current use mode of the seat body 120, thereby adjusting the seat body 120 to the correct use mode. Among them, the limit device 250 can be implemented by means such as an electromagnet.

[0125] The above-mentioned child safety seat control system locks the seat body by a limit device when the current usage mode is the correct usage mode, and releases the seat body by a limit device when the current usage mode is an incorrect usage mode, so that the seat body can be adjusted to the correct usage mode, thereby avoiding users from misusing the usage mode of the child safety seat and improving the safety of children riding in a vehicle.

[0126] In one embodiment, the controller 230 is configured to determine whether the current usage mode of the child safety seat 100 matches the child attributes of the child currently carried by the child safety seat 100; if they match, the seat body 120 is locked by the limit device 250, and if they do not match, the seat body 120 is unlocked by the limit device.

[0127] In one embodiment, the child safety seat control system 300 further includes an input device provided on the child safety seat 100; the controller 230 stores child attributes corresponding to different usage modes; the input device is configured to allow a user to input child attributes and transmit the input child attributes to the controller.

[0128] Specifically, the child safety seat system may be provided with an input device for the user to input the child attributes such as the age, weight and height of the user. The input device may transmit the child attributes input by the user to the controller 230. The detection device 210 may detect whether the seat body 120 is currently in the forward use mode or the rearward use mode, and then transmit information indicating the current use mode to the controller 230. The controller 230 may compare the child attributes corresponding to the current use mode with the stored child attributes. If the two match, it is determined that the current use mode is the correct use mode, and the limit device 250 is controlled to lock the seat body 120; if the two do not match, and the limit device 250 has locked the seat body 120, the limit device 250 is controlled to release the lock. In addition, the user may also input the child attributes through an external terminal device.

[0129] In one embodiment, the anti-misuse system further includes a reminder device 220 ; the reminder device 220 is configured to perform a reminder operation according to the current usage mode detected by the detection device 210 .

[0130] Specifically, when the controller 230 determines that the current usage mode is not the correct usage mode, the reminder device 220 can be controlled to remind the user, and the user can adjust the usage mode of the seat body 120 after receiving the reminder.

By reminding the user through the reminder device, the user can be effectively helped to adjust the seat to an appropriate usage mode, thereby avoiding the user from misusing the usage mode of the child safety seat and improving the safety of children riding in the vehicle.

[0131] In one embodiment, Fig.10 As shown, a child safety seat 100 is provided, comprising: a base 110, a seat body 120 arranged on the base 110 and an electrical pivot 140; the electrical pivot 140 comprises a base pivot 141 and a body pivot 142 which are engaged and coupled to each other; wherein the base pivot 141 is arranged on the base 110, and the body pivot 142 is arranged on the seat body 120, so as to exchange the signals generated by the base 110 and the signals generated by the seat body 120 with each other.

[0132] Among them, the seat body 120 is rotatably connected to the base 110; the seat body 120 rotates relative to the base 110 through the rotating shaft; the base pivot 141 is used to electrically connect with the electrical devices in the base; the body pivot 142 is used to electrically connect with the electrical devices in the seat body; the base pivot 141 is fixedly connected to the base 110, and the base pivot 141 has a base conductive part 1411; the body pivot 142 is fixedly connected to the seat body 120, and the body pivot 142 has a body conductive part 1421; the base conductive part 1411 and the body conductive part 1421 are rotatably electrically connected in the rotating shaft; the electrical devices in the base and the electrical devices in the seat body are electrically conductive through the electrical connection between the base conductive part 1411 and the body conductive part 1421.

[0133] First, it should be noted that the seat body 120 and the base 110 of the child safety seat 100 may be provided with various electrical devices such as a detection device, a reminder device, a controller, a drive device, and a limit device. Electrical devices may need to be electrically connected using cables. However, when the seat body 120 rotates relative to the base 110, the cables connecting the electrical devices will rotate accordingly, causing the cables to become entangled, thereby affecting the service life of the electrical devices.

[0134] The child safety seat 100 of the embodiment of the present application includes a base 110 and a seat body 120 rotatably connected to the base 110 for providing a seating space. The base 110 and the seat body 120 are rotatably connected via a rotating shaft 13. In order to prevent the cables connected between the electrical components of the child safety seat 100 from moving with the rotation of the base 110 and the seat body 120, the child safety seat 100 also includes an electrical pivot 140. The electrical pivot 140 includes a pivot for connecting with the electrical components ( Fig.10 The base pivot member 141 electrically connected to the seat body 120 and the electrical device (not shown) Fig.10 The seat body 120 is fixedly connected to the seat body 120, wherein the base pivot 141 is fixedly connected to the base 110, and the body pivot 142 is fixedly connected to the seat body 120, the base pivot 141 has a base conductive portion 1411, and the body pivot 142 has a body conductive portion 1421, the base conductive portion 1411 and the body conductive portion 1421 are rotatably electrically connected to each other in the rotating shaft 13, and the electrical connection between the base conductive portion 1411 and the body conductive portion 1421 makes the base electrical devices and the body electrical devices electrically conductive.

[0135] When the child safety seat 100 rotates, the base conductive portion 1411 and the main body conductive portion 1421 will rotate synchronously with the rotation of the base 110 and the seat body 120. Since the main body pivot 142 is fixedly connected to the seat body 120 and the base pivot 141 is fixedly connected to the base 110, the main body pivot 142 is in a stationary state relative to the main body electrical components, and the base pivot 141 is also in a stationary state relative to the base electrical components. On the one hand, when the base electrical device and the main body electrical device are directly connected by the electrical pivot 140, since there is no cable between the base electrical device and the main body electrical device, the cable will not be entangled, thereby solving the technical problem of cable entanglement; on the other hand, when the main body electrical device and the main body pivot 142 are electrically connected by a cable, the base electrical device and the base pivot 141 are also electrically connected by a cable, since the main body pivot 142 is in a stationary state relative to the main body electrical device, and the base pivot 141 is also in a stationary state relative to the base electrical device, the cable connected between the main body pivot 142 and the main body electrical device and the cable connected between the base pivot 141 and the base electrical device are both stationary, that is, the cable will not move with the rotation of the child safety seat 100, so that the entanglement phenomenon will not occur, which can also solve the technical problem of cable entanglement. Therefore, the child safety seat 100 of the embodiment of the present application changes the traditional method of directly connecting electrical devices with cables, and proposes that the electrical devices are electrically connected through the electrical pivot 140, which has a simple structure and can avoid cable entanglement.

[0136] refer to Figures 10 to 13The base conductive part 1411 and the body conductive part 1421 are conductive and rotatable plug-in structures. The body conductive part 1421 has a conductive recessed structure 143, and the base conductive part 1411 has a conductive protruding structure 144 that can be plugged into the recessed structure 143. Therefore, the plug-in structure can be composed of two parts: the recessed structure 143 and the protruding structure 144. In order to protect the conductor, the recessed structure 143 is covered with a first insulating shell 14111, and the base pivot 141 below the protruding structure 144 is covered with a second insulating shell 14211, that is, the protruding structure 144 protrudes outside the second insulating shell 14211. The protruding structure 144 can be plugged into and pulled out of the recessed structure 143. A recessed platform 1431 is provided at the bottom of the recessed structure 143, and a cone 1441 matching the recessed platform 1431 is provided at the top of the protruding structure 144. The cone 1441 is a chamfered structure, and the chamfered structure has a certain guiding effect, which facilitates the insertion of the protruding structure 144 into the recessed structure 143. After the protruding structure 144 is inserted into the recessed structure 143, the second insulating shell 14211 and the first insulating shell 14111 are in a butt contact, and the butt contact is a smooth structure. Of course, the recessed structure 143 can also be provided on the conductive part 1411 of the base, and the conductive protruding structure 144 that can be plugged into the recessed structure 143 is provided on the conductive part 1421 of the body.

[0137] Continue to refer Fig.10 The rotating shaft 13 connected between the base 110 and the seat body 120 includes a rotating shaft body 131 with a hollow structure. Both ends of the rotating shaft body 131 extend outwardly with a shoulder 1311. At the same time, a mounting hole 15 matching the rotating shaft 13 is opened at the rotating connection between the seat body 120 and the base 110. The rotating shaft 13 is installed in the mounting hole 15, and the base conductive part 1411 and the body conductive part 1421 are accommodated in the hollow structure of the rotating shaft 13. In addition, the main body pivot member 142 includes, in addition to the main body conductive portion 1421, a main body connecting portion 1422 for connecting to the seat body 120, and the plane where the main body connecting portion 1422 is located is orthogonal to the plane where the main body conductive portion 1421 is located. Similarly, the base pivot member 141 includes, in addition to the base conductive portion 1411, a base connecting portion 1412 for connecting to the base 110, and the plane where the base connecting portion 1412 is located is orthogonal to the plane where the base conductive portion 1411 is located. The orthogonal setting facilitates the smooth rotation of the base conductive portion 1411 and the main body conductive portion 1421.

[0138] In one embodiment, the electrical device in the base 110 or the electrical device in the seat body 120 includes at least one of a detection device, a reminder device, a controller, a drive device, and a limit device. The electrical device of the seat body 120 can also be a detection device for detecting whether the top strap of the seat body 120 is tightened, and the electrical device of the base 110 can also be an indicator for displaying the tightening status information of the top strap. When in use, the user can clearly know whether the top strap is in a tightened state according to the indicator. When the top strap is tightened, the indicator displays green, and when the top strap is in a non-tightened state, the indicator displays red.
