[0010] Furthermore, the first pressing member and the second pressing member are both buckling rings made of aluminum material.

[0011] Wherein, the driving assembly includes a driving motor and a connecting piece; the driving motor includes a housing, and the connecting piece passes through the housing and is connected to the valve body integrated mechanism, so that the driving motor is connected to the valve body integrated mechanism.

[0030] like Figure 1 As shown, the present invention provides an air supply unit, including a valve body integrated mechanism 1, a drive assembly, an air storage mechanism 4 and a connecting assembly; one end of the connecting assembly is connected to one end of the valve body integrated mechanism 1, and the other end of the connecting assembly is connected to the air storage mechanism 4 to form a soundproof cavity, and the drive assembly is connected to the valve body integrated mechanism 1 and is located in the soundproof cavity.

[0031] Compared with the prior art, the air supply unit provided by the present invention has the following advantages:

[0032] The air supply unit provided by the present invention can form a soundproof cavity by means of a connecting assembly provided between the valve body integrated mechanism 1 and the air storage mechanism 4. By connecting the driving assembly to the end of the valve body integrated mechanism 1, the driving assembly can be located in the soundproof cavity, thereby being able to isolate part of the noise generated when the driving assembly is started to a certain extent, thereby improving driving comfort.

[0033] Alternatively, if Figure 1 As shown, the connection assembly in the present application includes a bladder skin 8, one end of the bladder skin 8 is connected to the end of the valve body integrated mechanism 1, and the other end of the bladder skin 8 is connected to the end of the gas storage mechanism 4.

[0034] Since the bladder skin 8 has a certain degree of deformation, by arranging the bladder skin 8 between the valve body integrated mechanism 1 and the air storage mechanism 4, not only can the noise generated when the power component is started be shielded to a certain extent, but also the transmission of vibration between the two mechanisms can be blocked to a certain extent, that is, the vibration generated by the air storage mechanism 4 can be attenuated to a certain extent after being transmitted to the bladder skin 8, thereby reducing the influence of the vibration of the air storage mechanism 4 on the valve body integrated mechanism 1. Similarly, when the vibration generated when the power component is started is transmitted to the valve body integrated mechanism 1, the vibration can also be transmitted to the bladder skin 8 and attenuated, so that the influence of the vibration on the air storage mechanism 4 can be reduced through the bladder skin 8, thereby ensuring the stability and service life of the overall air supply unit.

[0035] Preferably, the bladder skin 8 in the present application is made of a rubber material combined with PET cords, which can have a certain strength to support the valve body integration mechanism 1 and the air storage mechanism 4, and can also have a corresponding degree of deformation to reduce the transmission of vibration.

[0036] Alternatively, if Figure 1 As shown, in order to improve the performance, a first annular groove 101 is formed along the circumference of the valve body integrated mechanism 1 and at the end of the valve body integrated mechanism 1, and a second annular groove 401 is formed along the circumference of the air storage mechanism 4 and at the end of the air storage mechanism 4; one end of the bladder skin 8 is embedded in the first annular groove 101 and connected to the valve body integrated mechanism 1, and the other end of the bladder skin 8 is embedded in the second annular groove 401 and connected to the air storage mechanism 4.

[0037] By forming a first annular groove 101 at the end of the valve body integrated mechanism 1 and a second annular groove 401 at the end of the air storage mechanism 4, the end of the bladder skin 8 can be embedded in the first annular groove 101 and the second annular groove 401, thereby improving the connection stability between the bladder skin 8 and the valve body integrated mechanism 1 and the air storage mechanism 4 to a certain extent.

[0038] Preferably, in the present application, a first protrusion is formed at one end of the bladder skin 8 and corresponds to the first annular groove 101, and a second protrusion is formed at the other end of the bladder skin 8 and corresponds to the second annular groove 401. By making the first protrusion snap into the first annular groove 101 and the second protrusion snap into the second annular groove 401, the stability of the connection between the bladder skin 8 and the valve body integration mechanism 1 and the air storage mechanism 4 can be further improved.

[0039] More preferably, if Figure 1 As shown, the connection assembly in the present application also includes a first pressing member 5 and a second pressing member 6; the first pressing member 5 presses one end of the bladder skin 8 into the first annular groove 101, and the second pressing member 6 presses the other end of the bladder skin 8 into the second annular groove 401.

[0040] The first clamping member 5 and the second clamping member 6 in the present application are both aluminum buckle rings. During assembly, the first clamping member 5 and the second clamping member 6 are first sleeved on the bladder skin 8, and then the two ends of the bladder skin 8 are respectively connected to the ends of the valve body integrated mechanism 1 and the ends of the air storage mechanism 4. Finally, the first clamping member 5 is moved to the position corresponding to the first annular groove 101, so that the first clamping member 5 is embedded in the first annular groove 101, and the second clamping member 6 is moved to the position corresponding to the second annular groove 401, so that the second clamping member 6 is embedded in the second annular groove 401, so that the ends of the bladder skin 8 can be pressed in the first annular groove 101 and the second annular groove 401, so as to improve the connection strength between the bladder skin 8 and the valve body integrated mechanism 1 and the air storage mechanism 4.

[0041] Among them, Figure 1 As shown, the driving assembly in the present application includes a driving motor 2 and a connecting member 7; the driving motor 2 includes a housing, and the connecting member 7 passes through the housing and is connected to the valve body integrated mechanism 1 to connect the driving motor 2 to the valve body integrated mechanism 1.

[0042] The housing in the present application is formed with a perforation, and the connecting member 7 passes through the perforation and is connected to the valve body integrated mechanism 1. It can be understood that if Figure 1 As shown, there are multiple connecting members 7 in the present application, and the multiple connecting members 7 are evenly spaced along the circumference of the shell, so that the connection between the drive assembly and the valve body integrated mechanism 1 can be more stable and the force can be more uniform. Accordingly, the valve body integrated mechanism 1 is formed with a connecting hole 102 at the position corresponding to the connecting member 7, and the through hole is relative to the connecting hole 102. The connecting member 7 passes through the through hole and is connected to the connecting hole 102, so that a stable connection between the drive assembly and the valve body integrated mechanism 1 can be achieved.

[0043] Preferably, if Figure 1 As shown, the connecting member 7 in the present application is a fastening bolt 3, and the connecting hole 102 is a screw hole, so as to achieve a quick connection between the drive assembly and the valve body integrated mechanism 1.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
