[0031] like Figure 1-5 As shown, in one embodiment of this utility model, an intelligent backrest child chair is provided, including a seat body 10, an airbag 20 disposed on the seat body 10, a pressure detection module, an electric air pump, and a control system. The airbag 20 is disposed on the front side wall of the backrest of the seat body 10, the pressure detection module is used to detect the air pressure inside the airbag 20, and the electric air pump is used to inflate or deflate the airbag 20.

[0032] The pressure detection module and the electric air pump are connected to the control system. The control system receives pressure data uploaded by the pressure detection module and compares the received pressure data with a built-in pressure threshold. When the pressure data received by the control system is less than the built-in pressure threshold, the control system sends an inflation signal to the electric air pump. In this embodiment, the pressure detection module uses a digital, diaphragm, or spring pressure sensor.

[0033] This embodiment discloses an intelligent backrest child chair. It incorporates an airbag 20 on the backrest of the seat body 10. When an electric air pump inflates the airbag 20, it supports the user's lower back, ensuring a consistent fit. This solves the problem of the user's lower back easily separating from the backrest when using conventional child chairs, thus providing excellent back support. Furthermore, a pressure detection module monitors the air pressure within the airbag 20. When the pressure data received by the control system is lower than a built-in pressure threshold, the control system sends an inflation signal to the electric air pump, which inflates the airbag 20, ensuring consistent air pressure and enhancing the back support effect.

[0034] In one embodiment, the control system includes a control module, a pressure detection module connected to the signal input terminal of the control module, and an electric air pump connected to the power output terminal of the control module. The control module controls the start or stop of the electric air pump by controlling the power supply to the power output terminal.

[0035] In one embodiment, the control system further includes an operation module connected to the control module. The operation module can be a combination of touch panel buttons or an external control terminal (such as a smartphone or remote control). By setting up the operation module, users can easily control the electric air pump.

[0036] In one embodiment, the control system further includes a wireless communication module, which is connected to both the control module and the operation module. By providing the wireless communication module and enabling it to communicate with an external gateway, the user can send control signals through an external control terminal. These control signals are transmitted to the control module via the wireless communication module, which then controls the air pump to operate based on the transmitted control signals. Specifically, the wireless communication module can be a Bluetooth module, a WiFi module, a 4G module, or a 5G module.

[0037] In one embodiment, the smart backrest child chair further includes an electric lifting mechanism 30, which drives the seat of the seat body 10 to lift. The electric lifting mechanism 30 includes a lifting motor 31, a lead screw 32, and a nut 33. The lifting motor 31 is located at the bottom of the seat of the seat body 10 and is connected to a power output terminal. The lead screw 32 is connected to the lifting motor 31, and the nut 33 is located on the seat leg of the seat body 10 and is threadedly engaged with the lead screw 32.

[0038] By designing an electric lifting mechanism 30, users can easily adjust the height of the seat body 10 to meet different usage needs and expand the applicability of this smart backrest child chair. Of course, it is understandable that users can send control signals to the control module via the operation module, and the control module will control the lifting motor 31 to operate according to the sent control signals.

[0039] In one embodiment, the electric lifting mechanism 30 further includes a housing 34 and a telescopic tube. The housing 34 is fixed to the bottom of the seat of the seat body 10, and a bracket 35 is installed inside the housing 34. The lifting motor 31 is fixed to the bracket 35. The telescopic tube surrounds the lead screw 32 and the nut 33. The telescopic tube includes a first tube 36 and a second tube 37 that telescopically engage. The first tube 36 is fixed to the seat leg of the seat body 10, and one end of the second tube 37 is fixedly connected to the bracket 35. By designing the telescopic tube, the lead screw 32 and the nut 33 can be concealed, making the appearance of the smart backrest child chair neater and more aesthetically pleasing.

[0040] In one embodiment, the lifting motor 31 is a stepper motor, a servo motor, a brushless geared motor, or a brushed geared motor.

[0041] In one embodiment, the bottom of the seat body 10 is provided with a mounting box 40, and the control module is located inside the mounting box 40. Using the mounting box 40 to house the control module not only enables the installation and fixation of the control module, but also provides protection for the control module, thus enhancing the safety of the intelligent backrest child chair.

[0042] In one embodiment, the electric air pump is housed within the mounting box 40, and the electric air pump has a connecting pipe 50 that extends out of the mounting box 40 and connects to the airbag 20. By integrating the electric air pump into the mounting box 40, the smart backrest child chair becomes more aesthetically pleasing and also provides protection for the electric air pump.
