The terms "first" and "second" are used solely to distinguish technical features and are not to be construed as indicating or implying relative importance, or as implicitly specifying the number or order of the technical features indicated.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted, connected, and connected" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0029] Reference Figures 1 to 3 An embodiment of the present application provides a seat control device, including: an airbag part; a control part, including a shell 210, a circuit board 220, an air valve assembly and a muffler 240, the shell 210 is provided with a accommodating cavity, the circuit board 220 is arranged in the accommodating cavity, the air valve assembly is arranged on the circuit board 220, the air valve assembly is connected to the airbag, the muffler 240 is arranged on the circuit board 220 and is located on one side of the air valve assembly, and the muffler 240 is connected to the air valve assembly; an air supply part 300, connected to the muffler 240.

[0030] The seat control device of the first embodiment of the present application forms a modular structure with the silencer 240, the circuit board 220, the air valve assembly, etc. by arranging the silencer 240 on the circuit board 220. There is no need to design the installation position of the silencer 240. The installation is simple and the work efficiency is improved. At the same time, the overall occupied area can be reduced and the space utilization rate can be improved.

[0031] Reference Figure 1 and Figure 2 In this embodiment, the housing 210 includes an upper shell 211 and a lower shell 212. The upper shell 211 and the lower shell 212 are connected to form a receiving cavity, thereby facilitating assembly and disassembly. The upper shell 211 and the lower shell 212 can be connected by means of buckles or screws, etc., which is not limited in this application.

[0032] Reference Figures 1 to 3The airbag unit includes a massage airbag 110 and a lumbar support airbag 120. The massage airbag 110 is used to provide a massage function, while the lumbar support airbag 120 is used to provide lumbar support. The massage airbag 110 and the lumbar support airbag 120 are respectively connected to the air valve assembly. By providing both the massage airbag 110 and the lumbar support airbag 120, the car seat can have both massage and lumbar support functions, realizing a multifunctional car seat, meeting user needs, and improving the user experience.

[0033] Furthermore, the air valve assembly includes a massage air valve 231 and a lumbar support air valve 232. The massage air valve 231 is connected to the massage airbag 110, and the lumbar support air valve 232 is connected to the lumbar support airbag 120. The massage air valve 231 and the lumbar support air valve 232 are respectively connected to a muffler 240. The muffler 240 is provided with an air inlet pipe 241 and an air outlet pipe 242. The air inlet pipe 241 is connected to the air supply unit 300, and the air outlet pipe 242 is respectively connected to the massage air valve 231 and the lumbar support air valve 232.

[0034] Specifically, when the massage air valve 231 is opened and the lumbar support air valve 232 is closed, the gas provided by the air supply unit 300 enters the muffler 240 through the air inlet pipe 241 for noise reduction, and then enters the air valve assembly through the air outlet pipe 242, and finally the massage air valve 231 sends the gas into the massage airbag 110. At this time, only the massage effect can be achieved; when the massage air valve 231 is closed and the lumbar support air valve 232 is opened, the gas provided by the air supply unit 300 enters the muffler 240 through the air inlet pipe 241 for noise reduction, and then enters the air valve assembly through the air outlet pipe 242. In the air valve assembly, the lumbar support air valve 232 finally delivers the gas into the lumbar support airbag 120, at which point only the lumbar support effect can be achieved; when the massage air valve 231 is opened and the lumbar support air valve 232 is opened, the gas provided by the air supply unit 300 enters the muffler 240 through the air inlet pipe 241 for noise reduction, then enters the air valve assembly through the air outlet pipe 242, and finally the massage air valve 231 and the lumbar support air valve 232 deliver the gas into the massage airbag 110 and the lumbar support airbag 120 respectively, at which point both the massage effect and the lumbar support effect can be achieved. By adopting the above structure, the different usage needs of users can be met and the user experience can be improved.

[0035] It should be noted that the air valve assembly can also be provided with only a massage air valve 231 or a lumbar support air valve 232, and the airbag part is correspondingly provided with only a massage airbag 110 and a lumbar support airbag 120. In this case, only one of the functions of massage or lumbar support can be achieved, resulting in a relatively single function of the car seat.

[0036] Reference Figures 1 to 3 It is conceivable that the air outlet pipe 242 is provided with a pressure relief valve 243. By providing the pressure relief valve 243 at the air outlet pipe 242, the pressure can be automatically relieved when the air pressure is too high, thereby improving the stability of the work and extending the service life.

[0037] It's easy to understand that the massage valve 231 and the lumbar support valve 232 are each equipped with a first silencer 233 and a second silencer 234. The first silencer 233 and the second silencer 234 are located on the exhaust side of the massage valve 231 and the lumbar support valve 232, respectively. The first silencer 233 and the second silencer 234 reduce noise during deflation of the massage valve 231 and the lumbar support airbag 120, improving the user experience.

[0038] Reference Figures 1 to 3 The circuit board 220 is provided with a power interface 221, which is provided through the housing 210 and is used to connect the power supply unit. By providing the power interface 221, it is easy to connect the control unit and the power supply unit, with a simple structure and easy operation.

[0039] Reference Figures 1 to 3 In some embodiments, the control unit further includes a felt cloth 250, which is used to connect to the car seat, and the shell 210 is disposed on the felt cloth 250. The provision of the felt cloth 250 facilitates the connection between the control unit and the car seat, thereby improving work efficiency. Furthermore, the shell 210 is provided with a mounting lug 213, and the mounting lug 213 is provided with a fastener, which is connected to the felt cloth 250. The fastener is configured as a rivet. By adopting the above structure, the stability of the connection between the shell 210 and the felt cloth 250 can be improved, thereby improving safety.

[0040] It should be noted that the outer shell 210 and the felt cloth 250 can also be connected by means of glue or the like. Those skilled in the art can make a reasonable choice based on actual conditions, and this application does not impose any restrictions on this.

[0041] A second aspect of the present application provides a car seat, comprising the seat control device described in the first aspect of the present application.

[0042] The car seat of the second embodiment of the present application forms a modular structure with the muffler 240 disposed on the circuit board 220, the muffler 240, the circuit board 220, the air valve assembly, etc., without the need for additional installation position design of the muffler 240, which facilitates installation and improves work efficiency. At the same time, it can also reduce the overall occupied area and improve space utilization.
