[0053] The following describes in detail the embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0054] As Figure 1 shown, the present invention provides a child safety seat, including a central processor 1, a sensing module 2, a function module 3 and a user control module 4. The sensing module 2, the function module 3 and the user control module 4 are respectively electrically connected to the central processor 1. The sensing module 2 is used to obtain and send a sensing signal to the central processor 1. The user control module 4 is used to obtain the operation information of the user and send a corresponding operation instruction to the central processor 1. The function module 3 is used to respond to the control instruction issued by the central processor 1 and implement the corresponding function.

[0055] The sensing module 2 includes a temperature sensing module 212 and a pressure sensing module 222. The function module 3 includes a blower 31, a voice sounding module 32 and a light indicating module 33. The user control module 4 includes a wind speed shifting module 41, a volume adjusting module 42, a sleep control module 43 and a brightness adjusting module 44.

[0056] The child safety seat includes a temperature control system. The temperature control system includes the temperature sensing module 212, the central processor 1 and a cooling module. The temperature sensing module 212 is used to obtain the ambient temperature signal and send it to the central processor 1. The central processor 1 is used to receive and process the ambient temperature signal, and issue a corresponding cooling instruction to the cooling module when the ambient temperature value is higher than the preset temperature value. The cooling module is used to receive the control instruction of the central processor 1 and perform cooling processing. In this embodiment, the cooling module is the blower 31. In other embodiments, the cooling module can also be a refrigeration device.

[0057] The temperature sensing module 212 can be used to detect the ambient temperature around the child safety seat. When the central processor 1 determines that the ambient temperature value is higher than the preset temperature value, the central processor 1 sends a cooling instruction to the fan 31 to start cooling, achieving the effect of preventing the safety seat from being too hot and causing discomfort to the child or posing a safety hazard to the child.

[0058] A plurality of preset temperature values are set, and the plurality of preset temperature values form a plurality of preset temperature ranges. In this embodiment, the plurality of preset temperature ranges are respectively set to three gears: below 25°, 25°-35°, and above 35°. When the ambient temperature value is higher than 25°, the fan 31 starts to work. The central processor 1 is used to judge the preset temperature range where the ambient temperature value is located and output a corresponding voltage signal to the fan 31 to enable the fan 31 to achieve multi-speed regulation. The wind speed of different gears of the fan 31 increases as the preset temperature value increases.

[0059] The central processor 1 outputs different voltages to the fan 31 according to the preset temperature range where the ambient temperature value is located, so as to achieve multi-speed regulation of the fan 31. When the ambient temperature is higher, the wind speed of the fan 31 is higher, accelerating the cooling speed and making the safety seat more intelligent.

[0060] The temperature control system further includes the wind speed shift module 41. The wind speed shift module 41 is used to send a fan shift instruction to the central processor 1 to enable the fan 31 to switch between the automatic gear and the manual gear. The central processor 1 is used to stop or start processing the ambient temperature signal after receiving the fan shift instruction. When the fan 31 switches from the automatic gear to the manual gear, the central processor 1 stops processing the ambient temperature signal. When the fan 31 switches from the manual gear to the automatic gear, the central processor 1 starts processing the ambient temperature signal.

[0061] The automatic gear is provided with a plurality of gears. The central processor 1 is used to output a corresponding voltage signal to the fan 31 according to the gear information after receiving the fan shift instruction (generated by the user clicking the manual gear).

[0062] The user can send a fan shift instruction to the central processor 1 through the wind speed shift module 41 to enable the fan 31 to switch between the automatic gear and the manual gear. When the fan 31 is in the automatic gear, the fan 31 can adjust the wind speed according to the ambient temperature. When the fan 31 is in the automatic gear, the fan 31 can adjust the wind speed according to manual control, making the safety seat more user-friendly and bringing a better user experience to the user.

[0063] The temperature control system further includes a prompt module, and the prompt module is the voice module 32. The central processor 1 is configured to send a control instruction to the voice module 32 to make the voice module 32 emit corresponding voice prompt information after receiving a fan gear shift instruction.

[0064] When the user manually shifts the gear of the fan 31, the voice module 32 can emit corresponding voice prompt information according to the gear switching information. The user can learn the current gear information from the voice prompt information, so as to adjust to the required gear. The voice prompt information emitted by the voice module 32 can provide an auxiliary function for the user's operation and bring convenience in operation.

[0065] The temperature control system further includes the volume adjustment module 42. The volume adjustment module 42 is configured to send a volume adjustment instruction to the central processor 1, and the central processor 1 is configured to receive the volume adjustment instruction and output a corresponding voltage signal to the voice module 32 to change the volume of the voice module 32.

[0066] The user can adjust the volume of the voice module 32 according to needs to meet the volume requirements in different scenarios, bringing a better user experience to the user.

[0067] The volume adjustment module 42 is provided with a plurality of volume adjustment gears. The central processor 1 is configured to receive the volume adjustment instruction and output a corresponding voltage signal to the voice module 32 according to the volume adjustment gear. Dividing the volume into multiple gears makes it more convenient and fast for the user to adjust the volume, improving the convenience of use.

[0068] The temperature control system further includes the pressure sensing module 222. The pressure sensing module 222 is configured to receive a touch pressure and send a touch pressure signal to the central processor 1. The central processor 1 is configured to send a control instruction to the fan 31 only when the ambient temperature value is higher than the preset temperature value and a touch pressure signal is received.

[0069] When a child is sitting on the safety seat, the pressure sensing module 222 receives the touch pressure of the child. When the child leaves the seat, the pressure sensing module 222 does not receive the touch pressure of the child. Therefore, when the child is sitting on the safety seat and the ambient temperature value is higher than the preset temperature value, the fan 31 starts to work, which can reduce the power consumption caused by the fan 31 continuing to work after the child leaves the seat.

[0070] The temperature control system further includes a timing module 5, which is used to calculate the touch duration of the pressure sensing module 222 and send a touch duration signal to the central processor 1. The central processor 1 is used to send a control instruction to the blower 31 when the touch duration is greater than a preset duration and the ambient temperature value is higher than the preset temperature value.

[0071] After a child sits on the safety seat, the timing module 5 starts timing. When the touch duration is greater than the preset duration and the ambient temperature value is higher than the preset temperature value, the blower 31 starts to work, which can avoid the blower 31 starting to work in the case of accidental touch rather than a child sitting, reducing power consumption and safety hazards.

[0072] The temperature control system further includes the light indication module 33. The central processor 1 is used to judge the preset temperature range where the ambient temperature value is located and send a corresponding light emission instruction to the light indication module 33. The light indication module 33 is used to emit a corresponding light indication signal after receiving the control instruction sent by the central processor 1.

[0073] In this embodiment, when the temperature is less than 25°, the light indication signal is default to green display. When the temperature is in the range of 25° - 35°, the light indication signal is default to blue display. When the temperature is higher than 35°, the light indication signal is default to orange display.

[0074] Different light indication signals can bring visual cues to the driver or accompanying personnel so as to know the temperature situation of the safety seat.

[0075] The temperature control system further includes a brightness adjustment module 44. The brightness adjustment module 44 is used to send a brightness adjustment instruction to the central processor 1. The central processor 1 is used to receive and process the brightness adjustment instruction and output a corresponding voltage signal to the light indication module 33 to adjust the brightness of the light indication module 33.

[0076] The driver or accompanying personnel can adjust the brightness of the light indication module 33 through the brightness adjustment module 44 to meet the needs in different brightness scenarios, making the safety seat more user-friendly.

[0077] The child safety seat further includes a safety prompt system. The safety prompt system includes the pressure sensing module 222, the central processor 1 and the voice sounding module 32. The pressure sensing module 222 is used to receive a touch action and send a touch signal to the central processor 1. The central processor 1 is used to receive and process the touch signal and send a control instruction to the prompt module. The prompt module is used to emit a prompt signal after receiving the control instruction of the central processor 1.

[0078] After the child is seated in the safety seat, the voice module 32 issues corresponding voice prompts according to the control instructions sent by the central processor 1, so as to remind the parent to fasten the seat belt for the child, prevent the parent from forgetting to fasten the seat belt for the child, and reduce potential safety hazards.

[0079] The pressure sensing module 222 is used to obtain and send the actual pressure value of the touch pressure to the central processor 1. The central processor 1 is used to send a control instruction to the voice module 32 to make it issue a voice prompt signal only when the actual pressure value is greater than the preset pressure threshold.

[0080] Only when the actual pressure value is greater than the preset pressure threshold does the voice module 32 issue a voice prompt signal, which can prevent false pressing from causing the voice module 32 to issue a voice warning and reduce the occurrence of false alarms.

[0081] The safety prompt system further includes the timing module 5. The timing module 5 is used to calculate the touch duration of the pressure sensing module 222 and send the touch duration signal to the central processor 1. The central processor 1 is used to send a control instruction to the prompt module to make it issue an indication signal only when the touch duration is greater than the preset duration and the actual pressure value is greater than the preset pressure threshold.

[0082] The timing module 5 can calculate the touch duration and send the touch duration signal to the central processor 1. When the central processor 1 determines that the touch duration is greater than the preset duration and the actual pressure value is greater than the preset pressure threshold, the voice module 32 issues a voice prompt signal; further preventing false alarms caused by false pressing, improving the user experience and safety.

[0083] The child safety seat further includes a wireless module 6 for connecting to a mobile terminal. In this embodiment, the wireless module 6 is a Bluetooth module. The wireless module 6 is electrically connected to the central processor 1. The wireless module 6 is used to receive and send the user control instructions sent by the mobile terminal to the central processor 1. The central processor 1 is used to receive, process the control instructions and send corresponding control instructions to the function module 3.

[0084] The user terminal is used to send a volume adjustment instruction, a brightness adjustment instruction, and a fan speed shift instruction to the central processor 1. The central processor 1 is used to receive, process the volume adjustment instruction, the brightness adjustment instruction, or the fan speed shift instruction and send control instructions to the voice module 32, the light indication module 33, or the fan 31 respectively, so as to adjust the volume size, the brightness size, and the fan 31 speed.

[0085] The user can wirelessly connect the mobile terminal to the child safety seat and send user control instructions through the mobile terminal, enabling the function module 3 to implement corresponding functions. Controlling with the mobile terminal improves the convenience of operation and increases the diversity of operations, providing the user with more choices in operation.

[0086] The sleep control module 43 is used to send a sleep control instruction to the central processor 1. The central processor 1 is used to send a lullaby start instruction or a lullaby stop instruction to the voice module 32 after receiving the sleep control instruction. The voice module 32 is used to play a lullaby or stop playing a lullaby after receiving the lullaby start instruction or the lullaby stop instruction. Playing a lullaby can provide music hypnosis for children and help them fall asleep.

[0087] As Figures 2 to 4 As shown, the child safety seat includes a child safety seat base and a seat body 7 installed thereon. The child safety seat base includes a base body 8.

The light-emitting component 97 can illuminate the function key 93, facilitating the user to accurately touch the function key 93 in a dim light environment. At the same time, the light-emitting component 97 emits light from the side and then scatters, which can avoid the discomfort caused by the glare of light to the user.

[0100] Second positioning holes 961 are respectively and correspondingly provided on the light guide film 96 and the control circuit board 91, and the light guide film 96 is adhesively fixed to the control circuit board 91. By using the second positioning holes 961, the positions of the light guide film 96 and the control circuit board 91 can be more accurate during adhesion, and it is more convenient and efficient.

[0101] An avoidance hole 918 is provided on the control circuit board 91 near the function key 93, an extension plate 919 that can be bent and passed through the avoidance hole 918 is provided on the control circuit board 91, the light-emitting member 97 is fixed to the extension plate 919, and an avoidance groove 86 corresponding to the avoidance hole 918 is provided on the base body 8. The extension plate 919 can be bent and enter the avoidance hole 918 and the avoidance groove 86, thereby reducing the distance between the control circuit board 91 and the touch panel 92 and improving the sensitivity of the touch of the function key 93.

[0102] As Figure 5 and Figure 6 As shown, the induction module 2 includes a sensing device. The sensing device includes a sensing circuit board 24 and an airbag 23 made of an elastic material. The airbag 23 is provided with a receiving opening 231 into which the sensing circuit board 24 can extend and be received in the airbag 23. A sealing body for sealing and isolating the sensing circuit board 24 from the external environment of the airbag 23 is provided at the receiving opening 231, and a pressure sensor and a temperature sensor are provided on the sensing circuit board 24.

[0103] The temperature sensor on the sensing circuit board 24 can monitor the ambient temperature, thereby obtaining the real-time temperature situation of the child sitting on the safety seat. At the same time, the pressure sensor can monitor the air pressure in the airbag 23. When the airbag 23 is pressed or the external air pressure changes, the air pressure in the airbag 23 changes. By monitoring the air pressure in the airbag 23, the pressure state of the child sitting on the safety seat can be obtained, so as to reduce potential safety hazards.

[0104] A wire 25 is connected to the sensing circuit board 24 and extends through the receiving opening 231 to the outside of the airbag 23. The wire 25 is used to connect to a connector. By using the wire 25 to connect the sensing circuit board 24, data transmission with the outside is carried out through the wire 25, improving the stability of data transmission. At the same time, the wire 25 is hermetically connected to the sealing body to fix the wire 25, thereby improving the connection strength between the sensing circuit board 24 and the airbag 23.

[0105] The receiving opening 231 is square, and both sides of the sensing circuit board 24 along the width direction of the receiving opening 231 are in contact with the airbag 23 and are relatively fixed. When the sensing circuit board 24 is fixed to the airbag 23, the sensing circuit board 24 is clamped in the receiving opening 231, restricting the movement of the sensing circuit board 24 along the width direction of the receiving opening 231 and improving the connection stability between the sensing circuit board 24 and the airbag 23.

[0106] A first positioning hole 241 is provided on the induction circuit board 24, and the sealing body passes through the first positioning hole 241. When the sealing body seals the storage opening 231, the sealing body passes through the first positioning hole 241, and the sealing body plays a limiting role on the induction circuit board 24, improving the connection stability between the induction circuit board 24 and the airbag 23.

[0107] The top surface of the airbag 23 is an arc-shaped surface with a central arch. The arc-shaped top surface enables a local position of the airbag 23 to be higher, making it easier for the airbag 23 to be pressed when a child is sitting on the seat, so that the pressure sensor in the airbag 23 can detect the pressure more accurately. At the same time, when the airbag 23 resets, since the space of the airbag 23 gradually becomes smaller from bottom to top, the gas in the airbag 23 flows concentratedly towards the top of the airbag 23 during the reset process of the airbag 23, making the airbag 23 rebound faster.

[0108] Both side surfaces of the airbag 23 first gradually widen and then gradually narrow until they intersect along the direction away from the storage opening 231, and the airbag 23 is leaf-shaped. When the airbag 23 is pressed, the gas in the airbag 23 is compressed and converges to the tip of the airbag 23. When the airbag 23 is released, the gas in the airbag 23 flows back from the tip to reset the airbag 23. Since the space at the tip of the airbag 23 decreases, it is beneficial for gas accumulation, and at the same time, the flow rate of the gas is faster when the gas is released, which is beneficial for the rapid reset of the airbag 23.

[0109] The bottom surface of the airbag 23 and the induction circuit board 24 are attached to the bottom of the airbag 23 and are parallel and attached to the induction circuit board 24. The bottom surface of the airbag 23 is attached to the induction circuit board 24, increasing the contact area between the induction circuit board 24 and the airbag 23, and improving the connection stability between the induction circuit board 24 and the airbag 23.

[0110] An arc-shaped side surface is connected between the bottom surface and the top surface of the airbag 23. The arc-shaped side surface makes the shape of the airbag 23 gradually contract inward from the top surface to the bottom surface, helping the gas to converge towards the middle of the airbag 23 when the airbag 23 is pressed and deformed, so that the pressure sensor can detect more accurately.

[0111] The present invention also provides a manufacturing method of the above sensing device, including the following steps:

[0112] The airbag 23 is formed by injection molding with an elastic material, and the elastic material is silica gel;

[0113] The induction circuit board 24 is placed into the airbag 23, and dry gas is added into the airbag 23;

[0114] The storage opening 231 is filled with liquid silica gel to seal the induction circuit board 24 in the airbag 23 and ensure that the gas in the airbag 23 is sufficient.

[0115] The above are only some embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
