DETAILED DESCRIPTION

[0059] 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.

[0060] 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.

[0061] Example 1

[0062] like Figure 1 As shown, this figure is a schematic diagram of the structure of an integrated pneumatic inflation device provided in an embodiment of the present application, and the device includes:

[0063] 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 a mounting port 6, and a mounting fixing portion 35 is provided in the gas storage cavity 3 corresponding to the mounting port 6;

[0064] It should be noted that if Figure 1 As shown, the gas storage tank 1 plays a role of buffering and storing 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 2 and diffuses and stays for a certain period of time, and can also stay in the gas storage chamber 3 for a long time to play a role of buffering and storing gas. Figure 4 As shown, at least one air outlet 4 connected to the air storage chamber 3 is provided on the tank body 2. The air outlet 4 is connected to the air storage chamber 3 and is used to communicate with the air-using component, so as to supply air to the air-using component. Among them, a quick-plug connection structure or an air nozzle structure is provided at the air outlet 4. 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 completed quickly.

[0065] Furthermore, if Figure 1 and Fig.26 As shown, the tank body 2 is further provided with a mounting opening 6, and a mounting fixing portion 35 is provided in the gas storage cavity 3 corresponding to the mounting opening 6; wherein the mounting opening 6 can be opened at the end or middle position of the tank body 2, such as Figure 3 and Figure 6 As shown, the mounting fixing portion 35 is recessed from the mounting opening 6 into the gas storage cavity 3 and forms a mounting cavity with the end cover 7, and the mounting cavity is used to mount the gas source assembly 10;

[0066] The mounting and fixing portion 35 may also be provided with an air inlet 5 , and the air inlet 5 is used to fill the air storage cavity 3 with gas.

[0067] A sealing structure 15 is provided between the outer wall of the air outlet nozzle 12 and the inner wall of the air inlet 5, and at the connection position for cooperating with the quick-plug connection structure. The sealing structure 15 plays a sealing role to prevent air leakage problems at the connection position of the corresponding components. Here, the material of the sealing structure 15 is, for example, rubber material. In addition, in order to improve the sealing effect of the sealing structure 15, the sealing structure 15 can also be designed to have a convex structure, and the convex structure is used to be connected with the surface form of the two components in an interference connection manner, thereby improving the sealing effect.

[0068] The end cover 7 is connected to the mounting port 6 and the gap formed by the connection between the end cover 7 and the mounting port 6 is sealed; an air inlet 8 is provided on the end cover 7; here, the air inlet 8 can be an air inlet hole or an air inlet channel.

[0069] The air source assembly 10 is fixedly arranged in the air storage chamber 3 through the fixed installation part 35; the air source assembly 10 has an air inlet nozzle 11 and an air outlet nozzle 12, the air inlet nozzle 11 is connected to the air inlet part 8 through the conduit 13, or the air inlet part 8 is plug-connected with the air inlet nozzle 11, and the air outlet nozzle 12 is connected to the air storage chamber 3 through the air inlet 5. The air source assembly 10 and the end cover 7 can be connected by a third screw 36. Here, as shown in FIG. Figure 6 As shown, the type of the conduit 13 is, for example, a hose, and the two ends of the hose are connected to the air inlet nozzle 11 and the air inlet portion 8 respectively. Fig.16 and Fig.17 As shown, the air inlet 8 is an elongated tube structure, and the elongated tube structure and the end cover 7 are an integrally formed structure. Fig. 20 As shown, a slot 34 is provided around the air inlet nozzle 11, and a sealing structure 15 is installed in the slot 34. The free end of the extended tube is plugged and connected to the air inlet nozzle 11. Fig.18 As shown, the sealing structure 15 abuts against the inner wall of the extension tube to achieve a sealing effect and avoid air leakage. Fig. 22 , Fig.23 , Fig.24 and Fig.26 As shown, the gas source assembly 10 is located at one end of the gas storage tank 1 and is arranged opposite to the gas inlet portion 4 .

[0070] The present application designs the gas storage tank 1 and the gas source component 10 as an embedded structure, the gas of the gas source component 10 enters the gas storage tank 1 through the air inlet part 8, the air inlet nozzle 11, and the air outlet nozzle 12, and the gas in the gas storage tank 1 enters the gas-using component through the air outlet part 4, thereby realizing inflation; the gas storage tank 1 and the gas source component 10 form an integrated structure, no matter how many gas-using components there are and how many gas-using parts the gas-using components contain, they are all supplied with gas by the same air outlet part, the layout of the entire device is simpler, the failure rate is reduced, and the cost is saved. At the same time, when the gas source component 10 is working, the gas flowing inside the gas storage tank 1 dissipates heat for the gas source component 10, reduces the influence of accumulated heat on the working efficiency of the gas source component 10, and can increase the life of the gas source component 10.

[0071] Among them, Fig.14 and Fig.23 As shown, the installation fixing portion 35 includes an end fixing portion 39 and an inner fixing portion 40, the end fixing portion 39 extends from the installation opening 6 into the air storage cavity 3, and the inner fixing portion 40 is arranged in the air storage cavity 3; the end fixing portion 39 and the inner fixing portion 40 are used to fix the air source component 10 in the air storage cavity 3, and when the gas flows in the air storage cavity 3, the heat generated by the air source component 10 can be taken away.

[0072] Furthermore, the air source assembly 10 includes an air pump body 16; at least one heat dissipation port 25 connected to the installation cavity is provided on the installation fixing portion 35, and the heat dissipation port 25 and the driving structure of the air pump body 16 are correspondingly arranged; here, the heat dissipation port 25 can also be used as an air inlet.

[0073] Among them, the air outlet nozzle 12 is located in the installation cavity, and the gas enters the air storage cavity 3 through the air outlet nozzle 12, the installation cavity and the heat dissipation port 25; the high-pressure gas compressed by the air pump body 16 flows in the installation cavity and then enters the air storage cavity 3 from the heat dissipation port 25. An air flow passage 38 can also be set to guide the gas flowing out of the air outlet nozzle 12 to the position of the driving mechanism of the air pump body 16 through the air flow passage 38, so that the air flow is directly blown to the driving mechanism, and then enters the air storage cavity 3 from the heat dissipation port 25, thereby improving the heat dissipation effect.

[0074] Alternatively, the air outlet nozzle 12 penetrates the installation cavity and extends into the air storage cavity 3; the driving device is exposed in the air storage cavity 3, and the flow of gas in the air storage cavity 3 dissipates heat for the driving structure.

[0075] like Figure 3 As shown, the heat dissipation port 25 in the figure is set on one side, that is, only one is opened on the mounting and fixing portion 35; Fig.12 and Fig.14 As shown, the heat dissipation opening 25 in the figure is provided on both sides, that is, the heat dissipation opening 25 is opened on two corresponding side walls of the installation opening 6.

[0076] The present application provides a heat dissipation port 25 corresponding to the driving structure of the air pump body 16 on the installation port 6, so that the gas in the air storage chamber 3 can accelerate the heat dissipation rate of the air pump body 16, and no additional devices are required, which can save costs to a certain extent.

[0077] Furthermore, a connector socket 37 electrically connected to the gas source assembly 10 is provided on the end cover 7 for obtaining electricity for the gas source assembly 10 .

[0078] Further, a seal 9 is provided on the end cover 7, and the seal 9 is used to block the gap between the end cover 7 and the installation opening 6, so that the installation chamber has a certain degree of sealing; here, the seal 9 is a sealing gasket or a sealing ring; the sealing gasket is wrapped around the outside of the end cover 7, or the sealing gasket or the sealing ring is provided along the circumference of the end cover 7. Fig.17 As shown in the figure, the sealing gasket is arranged along the circumference of the end cover 7. Fig.19 As shown in the figure, the sealing ring is arranged along the circumference of the end cover 7.

[0079] The present application utilizes a seal 9 to seal the gap between the end cover 7 and the mounting slot 6 to block the transmission of noise. Compared with the traditional method of adding sound-absorbing and shock-absorbing devices, the present application utilizes an installation chamber with a certain sealing property to achieve the purpose of sound-absorbing and shock-absorbing, and effectively saves costs.

[0080] Furthermore, it also includes:

[0081] The shock absorbing part is arranged between the inner wall of the end cover 7 and the air source assembly 10, and / or, between the inner wall of the mounting fixing part 35 and the air source assembly 10; the shock absorbing part plays a role in silencing and reducing noise. Here, the shock absorbing part is made of a flexible material, such as rubber.

[0082] Specifically, the shock absorbing part is a shock absorbing sleeve 14, and the shock absorbing sleeve 14 is connected with the inner wall of the end cover 7 and the air source component 10 by interference, and / or, the shock absorbing sleeve 14 is connected with the inner wall of the mounting fixing part 35 and the air source component 10 by interference. Figure 7 As shown in FIG. 1 , the shock absorbing sleeve 14 is located between the end cover 7 and the air source assembly 10. Figure 8 As shown, the figure is a schematic diagram of the structure in which the shock-absorbing sleeve 14 is located between the mounting and fixing part 35 and the air source assembly 10; when the air source assembly 10 is in working state, the air source assembly 10 will generate a certain degree of vibration and noise. If the air source assembly 10 is in direct contact with the inner wall of the end cover 7 or the inner wall of the mounting and fixing part 35, 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 10 itself, the shock-absorbing part is set between the inner wall of the end cover 7 and the air source assembly 10, and\or, between the inner wall of the mounting and fixing part 35 and the air source assembly 10, which plays a role in buffering and weakening the vibration and reducing the noise to a certain extent.

[0083] In addition, in order to ensure the shock-absorbing effect of the shock-absorbing sleeve 14, the shock-absorbing sleeve 14 is designed to have convex structures on both sides. The convex structures of the shock-absorbing sleeve 14 are used to abut against the corresponding wall surface to further enhance the shock-absorbing effect of the shock-absorbing sleeve 10 on vibration.

[0084] Furthermore, if Figure 5 and Fig.21 As shown, the gas source assembly 10 includes:

[0085] The air pump body 16 has an air outlet 17; a one-way valve 18 is provided at the air outlet 17. The one-way valve 18 is used to control the flow direction of the gas. Fig. 9 As shown, the one-way valve 18 includes: a valve body 32, which has an inlet end and an outlet end; a valve plug 33 is provided inside the valve body 32, and the two ends of the valve plug 33 are arranged in a one-to-one correspondence with the inlet end and the outlet end, and a spring 29 is sleeved on the valve plug 33, one end of the spring 29 is connected to the side wall of the valve plug 33, and the other end is abutted against the circumferential edge of the inlet end.

[0086] like Fig. 9 As shown in the figure, the one-way valve 18 is in an open state, that is, when the air pump body 16 is in a working state, the gas pushes the valve plug 22 of the one-way valve 18 to separate from the inlet end of the valve body 32, 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 18 is in a closed state, that is, when the air pump body 16 is in a stopped state, the gas pushes the valve plug 33 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 16.

[0087] The air pump cover 19 is provided on the end of the air pump body 16 provided with the one-way valve 18; the air pump cover 19 is provided with an air outlet nozzle 12; the air outlet nozzle 12 is connected to the air outlet end of the one-way valve 18. Here, the first screw 30 can be used to fix the various layers of the air source assembly 10.

[0088] Furthermore, if Fig.11 As shown, a protective cover 20 is provided on the air pump upper cover 19, and a receiving space 21 is formed between the protective cover 20 and the air pump upper cover 19;

[0089] The air pump upper cover 19 is provided with an air pressure monitoring nozzle 22 located inside the accommodation space 21, and the air pressure monitoring nozzle 22 extends into the air storage cavity 3;

[0090] The circuit board 23 is arranged on the side of the air pump cover 19 away from the air pump body 16. The circuit board 23 and the air pump body 16 are electrically connected to control the working state of the air pump body 16; and a retaining wall 41 is provided in the accommodating space 21, and an installation space is formed between the circuit board 23 and the retaining wall 41, and the installation space is connected to the space between the air pump cover 19 and the air pump body 16.

[0091] The air pressure sensor 24 is installed between the air pump upper cover 19 and the circuit board 23. The air pressure sensor 24 is located in the installation space, and the air pressure sensor 24 and the circuit board 23 are electrically connected.

[0092] The circuit board 23 is electrically connected to the air pump body 16 and the air pressure monitoring sensor 24 respectively, and the circuit board 23 is electrically connected to the external control module through a wire.

[0093] It should be noted that the air pressure sensor 24 is used to monitor the air pressure in the air storage chamber 3 .

[0094] Specifically, the monitoring end of the air pressure sensor 24 monitors the air pressure in the space between the air pump cover 19 and the air pump body 16. Since the space between the air pump cover 19 and the air pump body 16 is connected to the air storage chamber 3 through the air pressure monitoring nozzle 22, the air pressure actually monitored by the air pressure monitoring sensor 24 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 16 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 16 to stop working. Here, the preset value can be set according to actual conditions. The circuit board 23 is used to power the air pressure sensor 24, transmit the air pressure monitoring signal, and establish a connection relationship with the air pump body 16, thereby controlling the start and stop state of the air pump body 16. The protective cover 20 protects the circuit board 23.

[0095] Here, the circuit board 23 may be fixed by using the second screws 31 .
