DETAILED DESCRIPTION

[0047] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0048] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0049] Example 1

[0050] like Figure 1 As shown in the figure, this figure is a structural schematic diagram of a pneumatic system integrated inflation device for a vehicle seat provided in an embodiment of the present application, the device comprising:

[0051] The gas storage tank 1 comprises: a tank body 2, the interior of the tank body 2 is hollow to form a gas storage cavity 3, the tank body 2 is provided with at least one gas outlet 4 connected to the gas storage cavity 3, and the gas outlet 4 is used to communicate with the gas-using component; the tank body 2 is also provided with an air inlet 25 connected to the gas storage cavity 3, and the tank body 2 is also provided with a mounting groove 5, and the mounting groove 5 is arranged corresponding to the air inlet.

[0052] It should be noted that the gas storage tank 1 has a buffering and storage effect on the gas. The gas storage tank 1 includes: a tank body 2, the interior of the tank body 2 is hollow to form a gas storage chamber 3, and the high-pressure gas enters the internal space of the gas storage chamber 3 and diffuses and stays for a certain period of time. It can also stay in the gas storage chamber 3 for a long time, which plays a buffering and storage role for the gas. At least one gas outlet 4 is provided on the tank body 2, and the gas outlet 4 is connected to the gas storage chamber 3, and is used to connect with the gas-using component, so as to supply gas to the gas-using component. The tank body 2 is also provided with an air inlet 25, and the air inlet 25 is used to fill the gas storage chamber 3 with gas. Among them, the gas outlet 4 is provided with a quick-plug connection structure or a gas nozzle structure. Figure 2 As shown, a in the figure represents a quick-connection structure; Figure 5 As shown, b in the figure represents the air nozzle structure. It should be noted that the air outlet 4 is generally an air nozzle structure, which can be directly plugged and connected with the air pipe. This plug-in method has a slow installation speed and is difficult to plug in. In order to avoid the inconvenience of transportation after the air pipe is plugged in and the air nozzle is easy to break and to facilitate installation during seat assembly, the air outlet 4 is designed as a quick plug connection structure, and the air pipe is connected to the other end of the quick plug connection structure. When installed on the seat, the connection operation between the air outlet 4 and the air pipe can be quickly completed.

[0053] Specifically, the air inlet 25 can be opened at both ends of the tank body 2, or can be opened in the middle of the tank body 2. Figure 1 As shown in FIG. 2 , the air inlet 25 is opened at the end of the tank body 2 and is arranged adjacent to the air outlet 4; Figure 4 As shown in the figure, the air inlet 25 is opened in the middle of the tank body 2. Further, the tank body 2 is also provided with a mounting groove 5, which is arranged corresponding to the air inlet 25. The mounting groove 5 is opened at the end or the middle of the tank body 2 according to the position of the air inlet 25. Figure 1 As shown, when the air inlet 25 is opened at the end of the tank body 2, the mounting groove 5 is formed by the side wall of the tank body 2 protruding toward the end away from the tank body 2 in a direction parallel to the long axis of the tank body 2; Figure 4 As shown, when the air inlet 25 is opened in the middle position of the tank body 2, the mounting groove 5 is formed by the side wall of the tank body 2 being recessed into the air storage cavity 3 along a direction perpendicular to the long axis of the tank body 2.

[0054] For example, Figure 2 As shown, a seal 11 is provided at the connection position between the air outlet 4 and the air-using component to avoid air leakage at the connection position between the air outlet 4 and the air-using component. Fig.13 As shown, an air pressure monitoring sensor 16 may be installed around the air outlet portion 4 to monitor the air pressure in the air storage chamber 3 , so as to know whether it is necessary to start the air source assembly 10 to replenish the air in the air storage chamber 3 .

[0055] The end cover 6 is connected to the notch of the mounting groove 5 to form a mounting chamber, and the mounting chamber has an air inlet 26 connected to the ambient atmosphere; here, the air inlet 26 can be a hole opened on the mounting groove 5 or the end cover 6, or can be a hole such as Figure 1 and Figure 2 Here, the end cover 6 can be connected to the mounting groove 5 by a third screw 31.

[0056] The air source assembly 7 is arranged in the installation chamber; wherein the air source assembly 7 has an air outlet nozzle 9, and the air outlet nozzle 9 is connected to the air storage chamber 3 through the air inlet 25. Figure 1 and Figure 4 As shown, the air source component 7 and the air tank 1 form an integrated structure, that is, the air source component 7 is embedded in the air tank 1, and is used in conjunction with the air tank 1, which is more convenient; and the installation chamber wraps the air source component 7, which can block the transmission of noise and has a certain sound-absorbing effect.

[0057] Furthermore, the device also includes:

[0058] The shock absorbing part is arranged between the inner wall of the end cover 6 and the air source assembly 7, and / or, is arranged between the inner wall of the mounting groove 5 and the air source assembly 7.

[0059] The shock absorbing part may be provided between the inner wall of the end cover 6 and the air source assembly 7, and between the inner wall of the mounting groove 5 and the air source assembly 7, or only at one of the positions. Figure 7As shown in the figure, the shock absorbing part is arranged between the inner wall of the mounting groove 5 and the air source assembly 7; Figure 8 As shown in the figure, the shock absorbing part is arranged between the inner wall of the end cover 6 and the air source assembly 7; when the air source assembly 7 is in working state, the air source assembly 7 will generate a certain degree of vibration and noise. If the air source assembly 7 is in direct contact with the inner wall of the end cover 6 or the inner wall of the mounting groove 5, the aforementioned vibration will be transmitted to the shell and will also generate collision noise with the structure around the shell, making the noise larger. In order to avoid the influence caused by the vibration of the air source assembly 7 itself, the shock absorbing part is arranged between the inner wall of the end cover 6 and the air source assembly 7, and\or, between the inner wall of the mounting groove 5 and the air source assembly 7, which has a buffering and weakening effect on the vibration and reduces the noise to a certain extent. Here, the shock absorbing part is made of a flexible material, such as rubber.

[0060] In addition, the shock absorbing part is, for example, a shock absorbing sleeve 10; in order to ensure the shock absorbing effect of the shock absorbing sleeve 10, the shock absorbing sleeve 10 is designed to have a convex structure on both sides, such as Figure 8 As shown, the shock absorbing sleeve 10 and the inner wall of the end cover 6 and the air source assembly 7 are connected by interference, and\or, as Figure 7 As shown, the shock-absorbing sleeve 10 is interference-connected with the inner wall of the installation groove 5 and the air source assembly 7; the convex structure of the shock-absorbing sleeve 10 is pressed against the corresponding wall surface to further enhance the buffering effect of the shock-absorbing sleeve 10 on vibration.

[0061] Furthermore, if Figure 6 As shown, the shock absorbing sleeve 10 has a raised structure, which is located between the air outlet nozzle 9 and the air inlet 25 of the air storage tank 1. The raised structure abuts against the outer wall of the air outlet nozzle 9 and the inner wall of the air inlet 25 to form an interference connection, thereby improving the air tightness between the air outlet nozzle 9, the shock absorbing sleeve 10 and the air storage tank 1.

[0062] Furthermore, if Figure 3 As shown, the gas source assembly 7 includes:

[0063] The air pump body 12 has an air outlet channel 8; Fig.14 As shown, a one-way valve 13 is provided at the air outlet channel 8.

[0064] The one-way valve 13 is used to control the flow direction of the gas. Fig. 9 As shown, the one-way valve 13 includes: a valve body 28, which has an inlet end and an outlet end; a valve plug 29 is arranged inside the valve body 28, and the two ends of the valve plug 29 are arranged one-to-one with the inlet end and the outlet end, and a spring 30 is sleeved on one end of the valve plug 29 near the outlet end, and one end of the spring 30 abuts against the side wall of the valve plug 29, and the other end abuts against the circumferential edge of the inlet end. Fig. 9As shown in the figure, the one-way valve 13 is in an open state, that is, when the air pump body 12 is in a working state, the gas pushes the valve plug 29 of the one-way valve 13 to separate from the inlet end of the valve body 28, allowing the airway to be opened and the gas to flow out from the outlet end; Fig.10 As shown in the figure, the one-way valve 13 is in a closed state, that is, when the air pump body 12 is in a stopped state, the spring 30 pushes the valve plug 29 to block the inlet end, closing the airway, and the gas cannot flow reversely from the outlet end, thereby preventing the gas from overflowing from the air pump body 12.

[0065] The air pump upper cover 14 is covered on one end of the air pump body 12 having the one-way valve 13 ; an air outlet nozzle 9 is provided on the air pump upper cover 14 ; the air outlet nozzle 9 is communicated with the air outlet end of the one-way valve 13 .

[0066] In addition, a seal 11 is provided between the air outlet nozzle 9 and the air inlet 25, and at the position where the air outlet portion 4 is connected to the air-using component. The seal 11 plays a sealing role to prevent air leakage at the connection position of the two components. Here, the material of the seal 11 is, for example, rubber.

[0067] Here, the above components can be connected by screws. Figure 3 As shown, the first screws 23 are used to fix the various layers of the air pump body 12 .

[0068] Furthermore, if Fig.12 As shown, a protective cover 18 is provided on the air pump upper cover 14, and a receiving space 27 is formed between the protective cover 18 and the air pump upper cover 14; a retaining wall 22 is provided in the receiving space 27;

[0069] The air pump upper cover 14 is provided with an air pressure monitoring nozzle 15 passing through the accommodation space 27, and the air pressure monitoring nozzle 15 extends into the air storage cavity 3;

[0070] The circuit board 17 is arranged on a side of the air pump upper cover 14 away from the air pump body 12. The circuit board 17 is electrically connected to the air pump body 12 and is used to control the working state of the air pump body 12. An installation space is formed between the circuit board 17 and the retaining wall 22, and the installation space is connected to the space between the air pump upper cover 14 and the air pump body 12. Here, the circuit board 17 is fixed by a second screw 24.

[0071] An air pressure monitoring sensor 16 is disposed in the installation space, and the air pressure monitoring sensor 16 is electrically connected to the circuit board 17 .

[0072] The circuit board 17 is electrically connected to the air pump body 12 and the air pressure monitoring sensor 16 respectively, and the circuit board 17 is electrically connected to the external control module through a wire.

[0073] It should be noted that the air pressure monitoring sensor 16 monitors the air pressure in the air storage chamber 3 .

[0074] Specifically, the monitoring end of the air pressure monitoring sensor 16 monitors the air pressure in the space between the air pump cover 14 and the air pump body 12. Since the space between the air pump cover 14 and the air pump body 12 is connected to the air storage chamber 3 through the air pressure monitoring nozzle 15, the air pressure actually monitored by the air pressure monitoring sensor 16 is the air pressure in the air storage chamber 3. If the air pressure value in the air storage chamber 3 is less than the preset value, the external control module controls the air pump body 12 to work and inflate the air storage chamber 3. If the air pressure value is equal to or greater than the preset value, the external control module controls the air pump body 12 to stop working. Here, the preset value can be set according to actual conditions. The circuit board 17 is used to power the air pressure monitoring sensor 16, transmit the air pressure monitoring signal, and establish a connection relationship with the air pump body 12, thereby controlling the start and stop state of the air pump body 12. The protective cover 18 protects the circuit board 17.
