[0033] In order to make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be further described in detail below with reference to the drawings.

[0034] Figure 1 A perspective view of an air intake and exhaust pipe assembly in an existing embodiment is shown.

[0035] Reference Figure 1 The air intake and exhaust pipe assembly 100 includes a filter device 110, an air intake pipe 120 and an exhaust pipe 130. Specifically, as shown in Figure 1 The filter device 110 is connected with the air intake pipe 120, and the exhaust pipe 130 is connected with the air intake pipe 120 and is arranged in parallel, along a first direction (i.e. the axial direction of the filter device 110, as shown in the X direction in Figure 1 The air intake pipe 120 is arranged at the upper and lower ends of the filter device 110 to make the filter device 110 and the air intake pipe 120 in fluid communication.

[0036] The air intake and exhaust pipe assembly 100 further includes two buckles 140, which are arranged on opposite sides of the filter device 110 along the first direction X, and each buckle 140 is connected with the air intake pipe 120 and the exhaust pipe 130. That is, the exhaust pipe 130 is connected with the air intake pipe 120 near the upper and lower ends of the filter device 110 through the two buckles 140 to realize the fixation of the exhaust pipe 130.

[0037] However, the air inlet pipeline 120 and the air outlet pipeline 130 are connected by buckles, so that the distance between the air outlet pipeline 130 and the air inlet pipeline 120 is close. In order to maintain a safe distance between the air outlet pipeline 130 and the filter device 110, the air outlet pipeline 130 needs to avoid the filter device 110 arranged on the air inlet pipeline 120, which causes the air outlet pipeline 130 to be too curved, is not conducive to the production of the air pipe mold, and needs multiple buckles 140 (for example, two) to be fixed, which increases the production cost and difficulty.

[0038] To solve the above problems, the embodiment of the application provides a gas supply unit air pipe assembly. An interface is added to the filter for fixing the air outlet pipe, so as to reduce the bending of the air outlet pipe, save production materials and simplify the mold structure, reduce the production cost, and maintain a safe distance between the air outlet pipe and the filter.

[0039] Reference Figure 2 The embodiment of the application provides a gas supply unit air pipe assembly 200. The gas supply unit air pipe assembly 200 comprises an air inlet pipe 210, an air outlet pipe 220 and a filter 230 connected with the air inlet pipe 210. The filter 230 comprises a body part 231, a first connecting part 232 and a second connecting part 233.

[0040] For the convenience of subsequent description, the embodiment of the application first exemplarily defines the X direction and the Y direction. As shown in Figure 2 and Figure 3 The X direction (i.e. the first direction) is the axial direction of the filter 230, and the Y direction (i.e. the second direction) is the radial direction of the filter 230. The X direction is perpendicular to the Y direction. Hereinafter, the X direction and the Y direction are perpendicular to each other as an example.

[0041] It should be noted that the mutual perpendicularity in the application is not absolute perpendicularity. The approximate perpendicularity (for example, the included angle between two structural features is 89.9°) caused by processing errors and assembly errors is also within the range of mutual perpendicularity in the application. The limitation of mutual perpendicularity will not be repeated in the following description.

[0042] Specifically, as shown in Figure 2As shown, the air inlet pipe 210 and the air outlet pipe 220 both extend along the first direction X, the body part 231 has a top wall 2311, a bottom wall 2312 and a side wall 2313, the side wall 2313 of the body part 231 is connected with the top wall 2311 and the bottom wall 2312 respectively, and the top wall 2311 and the bottom wall 2312 of the body part 231 are both connected with the air inlet pipe 210 along the first direction X. The first connecting part 232 is arranged on the side wall 2313 of the body part 231, and the second connecting part 233 is connected with the air outlet pipe 220 so as to connect the air outlet pipe 220 with the body part 231 of the filter 230, and the second connecting part 233 is detachably connected with the first connecting part 232, thereby improving the convenience of connecting the air outlet pipe 220 with the filter 230 and facilitating the disassembly and assembly of the air supply unit pipe assembly 200.

[0043] Therefore, the filter 230 of the embodiment of the present application connects the air outlet pipe 220 with the air inlet pipe 210 through the filter 230 by arranging the first connecting part 232 and the second connecting part 233 on the side wall 2313 of the body part 231, so as to form the air supply unit pipe assembly 200, instead of directly connecting the air outlet pipe 220 with the air inlet pipe 210 through buckles.

[0044] Compared with the prior art air inlet and outlet pipe assembly 100 in which the air outlet pipe 220 is directly connected with the air inlet pipe 120 and arranged in parallel, the embodiment of the present application increases the air pipe interface (for example, the first connecting part 232) on the filter 230, which not only fixes the air outlet pipe 220 but also ensures the safety distance between the air outlet pipe 220 and the filter 230.

[0045] In addition, the air supply unit pipe assembly 200 of the embodiment of the present application is optimized from the original two buckle fixings to one interface fixing, which not only saves the number of fixing buckle parts, but also avoids the bending of the air outlet pipe 220 to avoid the filter 230, reduces the bending of the air pipe and reduces the production cost.

[0046] The specific structure of the brake master cylinder of the embodiment of the present application will be described in detail below with reference to the drawings.

[0047] As shown in Figure 2 and Figure 3 Exemplarily, the first connecting part 232 of the embodiment of the present application is a sliding groove 2321, and the second connecting part 233 includes a sliding block 2331, a clamping piece 2332 and an extension segment 2333. The sliding block 2331 is adapted to the sliding groove 2321 and is clamped with each other, so that the first connecting part 232 is detachably connected with the second connecting part 233.

[0048] Specifically, reference is made to Figure 4 and in combination with Figure 2 and Figure 3As shown, the clamping member 2332 includes: a base plate 2332a, a first side plate 2332b, and a second side plate 2332c. The first side plate 2332b is connected to the base plate 2332a, and the second side plate 2332c is connected to the base plate 2332a. The first side plate 2332b, the second side plate 2332c, and the base plate 2332a together define a clamping space 2332d, which is used to clamp the exhaust pipe 220.

[0049] And, as Figure 4 As shown, the first side plate 2332b has a first guide portion 2332e, and the second side plate 2332c has a second guide portion 2332f. The first guide portion 2332e and the second guide portion 2332f are disposed opposite to each other, and both the first guide portion 2332e and the second guide portion 2332f are used to guide the exhaust pipe 220 into the clamping space 2332d. That is, the exhaust pipe 220 enters the clamping space 2332d between the first guide portion 2332e and the second guide portion 2332f, and the first side plate 2332b and the second side plate 2332c apply pressure to the outer surface of the exhaust pipe 220 to clamp the exhaust pipe 220.

[0050] Thus, the clamping member 2332 engages with the exhaust pipe 220, the extension section 2333 extends along the second direction Y, one end 2333a of the extension section 2333 is connected to the slider 2331, and the other end 2333b of the extension section 2333 is connected to the clamping member 2332, so as to fix the exhaust pipe 220 to the body portion 231 of the filter 230.

[0051] For example, such as Figure 2 and Figure 4 As shown, the first side plate 2332b, the bottom plate 2332a, and the second side plate 2332c are connected in a U-shape. However, this is not a limitation; the embodiments of this application do not specifically limit the structure of the clamping member 2332. In other possible implementations, such as... Figure 3 and Figure 4 As shown, the first side plate 2332b, the bottom plate 2332a, and the second side plate 2332c can also be connected in sequence to form a C-shape, etc.

[0052] For example, such as Figure 4 As shown, in this embodiment of the application, the base plate 2332a, the first side plate 2332b, and the second side plate 2332c are integrally formed, that is, the clamping member 2332 in this embodiment of the application is integrally formed.

[0053] For example, such as Figure 4 As shown, the filter 230 in this embodiment further includes a third connecting portion 234, through which the filter 230 is mounted to the air supply unit (not shown in the figure). Furthermore, the body portion 231 in this embodiment has an upper end portion 231a and a lower end portion 231b.

[0054] Specifically, as Figure 4 and shown in Figure 2 shown, along the first direction X, the top wall 2311 is arranged at the upper end portion 231a, and the bottom wall 2312 is arranged at the lower end portion 231b, that is, the upper end portion 231a and the lower end portion 231b are respectively connected with the air inlet pipe 210 located on the upper and lower sides of the filter 230. Among them, the third connecting portion 234 is arranged at the upper end side wall 2313a of the upper end portion 231a, and the third connecting portion 234 is arranged in the third direction (that is, the circumferential direction of the filter 230, as shown in the R direction) and spaced apart from the first connecting portion 232. That is, along the first direction X, the projection of the third connecting portion 234 does not coincide with the projection of the first connecting portion 232, and the included angle of the third connecting portion 234 and the first connecting portion 232 relative to the center (as shown in O) of the body portion 231 is α, wherein 30°≤α≤180°. Figure 4 Figure 4

[0055] Exemplarily, the angle of the included angle α in the embodiments of the present application is not specifically limited, and the angle of the included angle α can be any value in 30° to 180°, for example, the angle of the included angle α can be 30°, 60°, 90°, 120° or 180°, etc.

[0056] As Figure 2 and shown in Figure 4 shown, the bottom plate 2332a of the U-shaped clamping piece 2332 is connected with the other end 2333b of the extension section 2333, and the included angle of the first connecting portion 232 and the third connecting portion 234 corresponding to the U-shaped clamping piece 2332 relative to the center (as shown in O) of the body portion 231 is α1, wherein α1=180°. Figure 4

[0057] And, as Figure 2 shown, the first connecting portion 232 is arranged at the lower end side wall 2313b of the lower end portion 231b, so as to facilitate adjusting the position of the first connecting portion 232 relative to the third connecting portion 234 according to actual conditions, for example, when welding the upper end portion 231a and the lower end portion 231b of the body portion 231, rotating the angle of the lower end portion 231b can adjust the angle of the included angle α1, and then adjust the position of the first connecting portion 232 relative to the third connecting portion 234, increase the structural diversity of the air supply unit air pipe assembly 200 of the embodiments of the present application, and facilitate assembly and use.

[0058] The embodiments of the present application do not specifically limit the arrangement of the first connecting portion 232 on the body portion 231 of the filter 230, in the above embodiments, the first connecting portion 232 is arranged at the lower end portion 231b of the body portion 231, and the clamping piece 2332 of the second connecting portion 233 is in U shape.

[0059] ​​​But not limited to this, in other possible embodiments, such as Figure 3 And in combination Figure 4 As shown in the first connecting portion 232 can also be provided in the body portion 231 upper end 231a, and the second connecting portion 233 of the clamping member 2332 is C-shaped, such as Figure 4 As shown in the first connecting portion 232 can also be provided in the body portion 231 upper end 231a, and the second connecting portion 233 of the clamping member 2332 is C-shaped, such as Figure 4 As shown in the first connecting portion 232 can also be provided in the body portion 231 upper end 231a, and the second connecting portion 233 of the clamping member 2332 is C-shaped, such as
