[0033] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0034] The following embodiments are described to aid in understanding this application. These embodiments are not, and should not be construed as, limiting the scope of protection of this application.

[0035] In the following description, those skilled in the art will recognize that throughout this discussion, components may be described as individual functional units (which may include subunits), but those skilled in the art will recognize that various components or portions thereof may be divided into individual components or may be integrated together (including integrated within a single system or component).

[0036] Furthermore, the connection between components or systems is not intended to be limited to a direct connection; on the contrary, data between these components may be modified, reformatted, or otherwise altered by intermediate components. Additionally, other or fewer connections may be used. It should also be noted that the terms "connection," "link," or "input" should be understood to include direct connections, indirect connections via one or more intermediate devices, and wireless connections. Example 1:

[0037] like Figure 1 As shown, a composite pneumatic quick-connect coupling system with an anti-misinsertion mechanism includes:

[0038] Controller assembly: The upper cover 101 and the lower cover 102 are detachably connected by a snap-fit ​​structure to form a cavity 103;

[0039] Valve body assembly 104: disposed within the cavity, integrating at least one set of male plug-in terminals 105;

[0040] Female module 200: Multiple plug-in female terminals 202 are integrated through a long horizontal plate 201, and an asymmetrical anti-misinsertion guide structure 203 is provided on the outer wall of the horizontal plate;

[0041] Interlocking mechanism: The plug mounting mechanism 106 extending from the controller assembly forms a mounting groove 107, which is axially locked with the elastic buckle 204 of the female module. When the elastic buckle 204 is engaged with the mounting groove 107, acoustic feedback is generated.

[0042] Airway connection structure: A set of male plug-in terminals 105 are connected to their corresponding female plug-in modules 200, and the number of male plug-in terminals 105 is the same as the number of corresponding female plug-in terminals 202, so that the airway is connected when the male plug-in terminals 105 are connected to the female plug-in terminals 202.

[0043] The air circuit integration structure of the valve body assembly 104 is as follows: all male plug-in terminals 105 are connected in series to the main air circuit 400, the first male plug-in terminal 105 is provided with an air inlet 401, and the last male plug-in terminal 105 is provided with a pressure relief pipe 402, which simplifies the air circuit layout and prevents over-inflation damage to the airbag by pressure relief at the end.

[0044] The inner wall of the cavity 103 is provided with a limiting step 111. The body of the valve body assembly 104 is mounted on the step, and the male plug-in end 105 extends into the mounting groove 107 to isolate the vibration of the outer shell from being transmitted to the valve body and improve the stability of the air circuit control.

[0045] like Figure 2-9 As shown, the inner side of the mounting groove 107 of the plug mounting mechanism 106 is provided with a sliding groove 108 and a locking groove 109. The body of the female module 200 is correspondingly provided with a locking block 205 and a locking hook 206. The sliding groove 108 and the locking block 205 cooperate to provide radial limiting, and the locking groove 109 and the locking hook 206 cooperate to interlock. The sliding groove 108 and the locking groove 109 are arranged opposite to the anti-misinsertion guide structure 203. The locking groove 109 is placed between adjacent sliding grooves 108. The locking block 205 is located on the outer surface of the female plug 202, and the locking hook 206 is located between adjacent female plugs 202. This achieves precise radial positioning of the female module 200 and the male plug 105 of the controller assembly, preventing plug-in offset.

[0046] When at least two sets of male terminals 105 are plugged in, the number of hooks 206 is set differently according to the numbering of the female terminal module 200. The number of hooks 206 of different numbered female terminal modules 200 is different, forming a unique physical error prevention code. For example, there are two hooks 206 for number A, and there are also two corresponding slots 109. There is one hook 206 for number B, and there is also one corresponding slot 109. Through the unique physical structure code, incorrect plugging of female terminal modules 200 with different numbers is prevented.

[0047] The anti-misinsertion guide structure 203 is a transverse rib, and the inner side of the mounting slot 107 of the controller component is provided with a matching anti-reverse snap-fit ​​slot 110. The asymmetrical rib is used for forced guidance to realize the anti-reverse insertion function.

[0048] When at least two sets of male terminals 105 are connected, the position and number of the anti-misinsertion guide structures 203 are set differently according to the numbering of the female terminal modules 200. The distribution position and number of the anti-misinsertion guide structures 203 on the long horizontal plate 201 are different for female terminal modules 200 with different numbers, forming a unique physical error prevention code. For example, the anti-misinsertion guide structure 203 numbered A is one and is set in the middle, and its corresponding mounting slot 107 is also one and is set in the middle. The anti-misinsertion guide structure 203 numbered B is two and is set on both sides, and its corresponding mounting slot 107 is also two and is set on both sides, forming a second layer of physical error prevention code, which works in conjunction with the hook code to improve the reliability of anti-misinsertion.

[0049] like Figure 10 As shown, the inner wall of the plug-in female end 202 is provided with at least two circumferentially spaced muffler positioning ribs 207. The positioning ribs include an axial guide part 207a and a radial anti-detachment part 207b, forming an interference fit cavity for the muffler, which simultaneously solves the problems of muffler assembly guidance and anti-detachment under vibration conditions.

[0050] The male connector 105 and the female connector 202 are provided with a sealing system 300. The female connector 202 has a built-in elastic seal 301. The male connector 105 has a limiting structure for the elastic seal 301 to ensure that the axial pressing force of the elastic seal 301 is uniform and to eliminate the risk of uneven wear and leakage caused by oblique insertion.

[0051] The beneficial effects of this utility model are as follows: This utility model proposes a composite air circuit quick-connect coupling system with an anti-misinsertion mechanism, including a controller assembly, a valve body assembly, a female end module, and an interlocking mechanism. The controller assembly consists of an upper cover and a lower cover connected by a snap-fit ​​structure to form a cavity. The valve body assembly is installed inside the cavity, integrating at least one set of male plug-in terminals. The female end module integrates multiple female plug-in terminals through a long horizontal plate, and the outer wall of the horizontal plate is provided with an asymmetrical anti-misinsertion guide structure. The interlocking mechanism is axially locked between the mounting groove of the controller assembly and the elastic snap-fit ​​of the female end module. The air circuit connection structure achieves air passage connection through the equal number of male and female terminals, solving the problems of reversed air circuit connection and low assembly efficiency, and improving the reliability and safety of the car seat massage system.

Various modifications and improvements can be made without departing from the concept of this application, and these all fall within the scope of protection of this application. The various aspects and embodiments disclosed in this application are for illustrative purposes only and are not intended to limit this application.
