Abstract
Description
Technical Field
[0001] This utility model relates to the field of air suspension technology, and more specifically, to a valve block structure and an air suspension. Background Technology
[0002] With the rapid development of electric vehicles, air suspension is becoming increasingly popular. An air suspension system consists of components such as air springs, sensors, and an air supply unit. The air supply unit uses a valve block as its basic component, with other related parts such as motors, solenoid valves, and plugs mounted on the valve block.
[0003] Currently, in the design and production process, the air suspension's air outlet pipe is directly connected to the solenoid valve of the valve block. However, moisture can condense on the air suspension's air outlet pipe. This condensed moisture can easily flow back into the valve block and then into the solenoid valve, causing the air suspension's air supply valve block to malfunction. This issue needs to be addressed. Utility Model Content
[0004] The purpose of this utility model is to provide a valve block structure and an air suspension, which forms a U-shaped exhaust structure and a clever air path layout to prevent the exhaust system of the air suspension from producing a siphon phenomenon, thereby avoiding the condensation of air impurities or moisture into the valve block and improving the service life of the air suspension exhaust valve block.
[0005] On one hand, the valve block structure provided by this utility model includes: a valve body and an exhaust valve mounting part disposed on the valve body. The valve body is provided with: an air inlet channel, one end of which is connected to the air inlet end of the exhaust valve mounting part, and the other end of which penetrates through the side wall of the valve body to form an air inlet; and an air outlet channel, one end of which is connected to the air outlet end of the exhaust valve mounting part, and the other end of which penetrates through the side wall of the valve body to form an air outlet. The air outlet channel includes a first channel and a second channel. The first channel connects the exhaust valve mounting part and the second channel, and the second channel connects the first channel and the air outlet. The height of the connection between the first channel and the second channel is higher than the height of the air outlet.
[0006] With this design, when water molecules in the air condense at the air outlet or impurities are located at the air outlet, the air outlet channel includes a first channel and a second channel, and the height of the connection between the first channel and the second channel is higher than the height of the air outlet. This makes it difficult for the condensed water droplets or impurities to enter the higher first channel under the action of gravity, and thus difficult to enter the exhaust valve mounting part. This prevents impurities or moisture in the air from condensing and entering the valve block, thereby improving the service life of the air suspension exhaust valve block.
[0007] Optionally, the first channel includes a first air passage and a second air passage, the first air passage connecting the exhaust valve mounting part and the second air passage, the second air passage connecting the first air passage and the second channel, and the first air passage and the second air passage being arranged perpendicularly.
[0008] This configuration, by setting up a vertical first and second air passage, increases the length of the first passage and thus increases its curvature, thereby increasing the difficulty for water droplets or impurities to enter the exhaust valve mounting part from the first and second air passages.
[0009] Optionally, the second channel includes a third air passage and a fourth air passage, the third air passage connecting the second air passage and the fourth air passage, the fourth air passage connecting the third air passage and the air outlet, and the third air passage and the fourth air passage being arranged perpendicularly.
[0010] This design, by setting up vertical third and fourth air channels, increases the length of the second channel, thereby increasing the curvature of the second channel and making it more difficult for water droplets or impurities to enter the first channel from the third and fourth air channels.
[0011] Optionally, the second channel further includes a fifth air passage, which connects the fourth air passage and the air outlet, and the fifth air passage is arranged perpendicularly to the fourth air passage.
[0012] This configuration, with the fifth and fourth air passages perpendicular to each other, further increases the curvature of the second channel, which helps to isolate water droplets or impurities within the second channel.
[0013] Optionally, the second airway is arranged perpendicular to the third airway, and the first airway is arranged parallel to the third airway.
[0014] This configuration results in the path shapes of the first, second, and third airways forming an inverted U-shape, with the second airway at the top of the U-shaped path, which helps to enhance the height of the connection between the first and second airways relative to the air outlet.
[0015] Optionally, the second airway is arranged perpendicular to the fourth airway.
[0016] This configuration, by offsetting the extension directions of the first and second channels in the second airway, causes the first and second channels to extend and bend in two perpendicular directions, which helps to increase the bending complexity of the first and second channels.
[0017] Optionally, the third airway is arranged perpendicular to the fifth airway.
[0018] This configuration makes the third, fourth, and fifth air passages perpendicular to each other, further increasing the bending complexity of the second channel within the valve block.
[0019] Optionally, the extension directions of the first air passage and the third air passage are perpendicular to the first side wall of the valve body, the extension direction of the fourth air passage is perpendicular to the second side wall of the valve body, and the extension direction of the fifth air passage is perpendicular to the side wall of the valve body where the air outlet is located. The first side wall and the second side wall are both adjacent to the side wall of the valve body where the air outlet is located.
[0020] This configuration, which sets up two adjacent air passages in the first and second channels vertically, increases the bending complexity of the first and second channels on the one hand, and on the other hand, the vertical relationship between the two adjacent air passages makes the opening angle fixed, which makes it convenient for operators to open the holes according to the fixed angle to form each air passage, thereby improving the accuracy of opening holes to form air passages on the valve block.
[0021] Optionally, a plurality of air holes are provided on the side wall of the valve body. The air holes are respectively connected to the first air passage and the third air passage on the first side wall, the fourth air passage on the second side wall, the second air passage on the side wall of the valve body where the exhaust valve mounting part is located, and the fifth air passage on the side wall of the valve body where the air outlet is located. A block is provided in the air hole.
[0022] This configuration allows the first, second, third, fourth, and fifth air passages to be sequentially opened through a plane perpendicular to the side wall of the valve block. After opening, these passages are sealed with plugs, creating a sequentially connected and closed first and second channel inside the valve block. This facilitates the formation of mutually perpendicular first, second, third, fourth, and fifth air passages.
[0023] Secondly, this utility model provides an air suspension system, including the valve block structure as described in the first aspect.
[0024] The technical effects of any possible implementation of the second aspect can be found in the technical effects of the first aspect mentioned above, and will not be repeated here.
[0025] The beneficial effects of the valve block structure and air suspension provided by this utility model embodiment include:
[0026] (1) The height of the connection between the first channel and the second channel is higher than the height of the air outlet, so that the condensed water droplets or impurities are difficult to enter the higher first channel under the action of gravity, and thus difficult to enter the exhaust valve installation part, thereby avoiding the condensation of air impurities or moisture into the valve block and improving the service life of the air suspension exhaust valve block.
[0027] (2) The two adjacent air passages in the first channel and the second channel are set vertically. On the one hand, the bending complexity of the first channel and the second channel is increased. On the other hand, the angle of the opening is fixed by the vertical relationship between the two adjacent air passages, which makes it convenient for the operator to open the holes according to the fixed angle to form each air passage, thereby improving the accuracy of opening holes to form air passages on the valve block.
[0028] (3) By setting air holes and plugs, the first air passage, the second air passage, the third air passage, the fourth air passage and the fifth air passage are opened in sequence. After the opening is completed, the plugs are sealed, so that the first and second channels are connected and closed in sequence inside the valve block, which helps to form the first, second, third, fourth and fifth air passages that are perpendicular to each other.

Detailed Implementation
[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0038] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0039] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0040] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0041] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0042] As described in the background section, the air supply unit of an air suspension typically uses a valve block as a basic component, which houses a turbocharger, an air tank, and a solenoid valve. The turbocharger is a key component in the air suspension system, supplying compressed air to the air tank or directly to the air springs. The air tank stores a certain amount of compressed air; when the system needs to quickly adjust the vehicle height, compressed air can be directly drawn from the tank without waiting for the turbocharger to compress air in real time, thus accelerating the system's response. The solenoid valve controls the direction and flow rate of compressed air in the turbocharger and air tank, allowing for precise control of the air spring's inflation and deflation.
[0043] However, the current air suspension's air outlet pipe is directly connected to the solenoid valve of the valve block. Since moisture can condense on the air suspension's air outlet pipe, the condensed moisture can easily flow back into the valve block and then into the solenoid valve, causing the air suspension's air supply valve block to malfunction. This needs to be improved.
[0044] To address these issues, this application provides a valve block structure and an air suspension system. The valve block structure and air suspension system provided by this utility model are described in detail below with reference to the embodiments and accompanying drawings. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.
[0045] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the valve block provided in this embodiment. Figure 2 This is a first-view cross-sectional view of the valve block provided in this embodiment. The valve block structure includes a valve body 1 and an exhaust valve mounting part 2 disposed on the valve body 1. The valve body 1 is provided with an air inlet channel 11 and an air outlet channel 12. One end of the air inlet channel 11 is connected to the air inlet end of the exhaust valve mounting part 2, and the other end penetrates through the side wall of the valve body 1 to form an air inlet 111. One end of the air outlet channel 12 is connected to the air outlet end of the exhaust valve mounting part 2, and the other end penetrates through the side wall of the valve body 1 to form an air outlet 121. The air outlet channel 12 includes a first channel 122 and a second channel 123. The first channel 122 connects the exhaust valve mounting part 2 and the second channel 123, and the second channel 123 connects the first channel 122 and the air outlet 121. The height of the connection between the first channel 122 and the second channel 123 is higher than the height of the air outlet 121.
[0046] In this embodiment, the exhaust valve mounting part 2 is located at Figure 2 In the middle, the height of the air inlet 111 on the valve body 1 is higher than the height of the air outlet 121. The first channel 122 is located between the exhaust valve mounting part 2 and the second channel 123, and the second channel 123 is located between the first channel 122 and the air outlet 121. The height of both the first channel 122 and the second channel 123 in the valve body 1 is higher than that of the exhaust valve mounting part 2 and the air outlet 121, so as to increase the height of the first channel 122 from the air outlet 121 to the exhaust valve mounting part 2. The height difference is used to prevent water droplets or impurities from the air outlet 121 from entering the exhaust valve mounting part 2 from the second channel 123 and the first channel 122.
[0047] In some embodiments, the first channel 122 includes a first air passage 1221 and a second air passage 1222. The first air passage 1221 connects the exhaust valve mounting portion 2 and the second air passage 1222. The second air passage 1222 connects the first air passage 1221 and the second channel 123, and the first air passage 1221 and the second air passage 1222 are arranged perpendicularly.
[0048] Specifically, the first air passage 1221 is located above the exhaust valve mounting portion 2 within the valve body 1 and is perpendicular to the opening direction of the exhaust valve mounting portion 2. The second air passage 1222 communicates with the end of the first air passage 1221 away from the exhaust valve mounting portion 2; that is, the height of the second air passage 1222 is higher than that of the first air passage 1221 and the exhaust valve mounting portion 2. The height of the end of the second air passage 1222 away from the first air passage 1221 is higher than that of the second channel 123, so that the height of the connection between the first channel 122 and the second channel 123 is higher than that of the air outlet 121.
[0049] Further, see Figure 2 and Figure 3 , Figure 3 This is a second-view cross-sectional view of the valve block provided in this embodiment. The second channel 123 includes a third air passage 1231 and a fourth air passage 1232. The third air passage 1231 connects the second air passage 1222 and the fourth air passage 1232. The fourth air passage 1232 connects the third air passage 1231 and the air outlet 121. The third air passage 1231 and the fourth air passage 1232 are arranged perpendicularly.
[0050] Specifically, the end of the third air passage 1231 furthest from the second air passage 1222 is connected to the fourth air passage 1232, such that the height of the fourth air passage 1232 within the valve body 1 is lower than that of the third air passage 1231. It should be noted that the length of the third air passage 1231 is longer than that of the first air passage 1221, therefore the height of the fourth air passage 1232 within the valve body 1 is lower than the height of the exhaust valve mounting portion 2.
[0051] Furthermore, the second air passage 1222 and the third air passage 1231 are arranged perpendicularly. The first air passage 1221 and the third air passage 1231 are arranged parallel to each other, so that the first air passage 1221, the second air passage 1222 and the third air passage 1231 form an inverted "U" shape, thereby preventing water droplets or impurities entering from the air outlet 121 from entering the first air passage 1221 and the exhaust valve mounting part 2 through the second air passage 1222 located at the highest point in the valve body 1.
[0052] Furthermore, the second air passage 1222 and the fourth air passage 1232 are arranged perpendicularly. It can be understood that the extension direction of the fourth air passage 1232 is perpendicular to the plane formed by the first air passage 1221, the second air passage 1222 and the third air passage 1231, so as to shorten the distance between the fourth air passage 1232 and the exhaust valve mounting part 2, which helps to reduce the thickness of the valve body 1.
[0053] In some embodiments, see Figure 3 and Figure 4 , Figure 4The third-view cross-sectional view of the valve block provided in this embodiment shows that the second channel 123 also includes a fifth air passage 1233. The fifth air passage 1233 connects to the fourth air passage 1232 and the air outlet 121. The fifth air passage 1233 is arranged perpendicularly to the fourth air passage 1232.
[0054] Specifically, the fifth airway 1233 connects to the end of the fourth airway 1232 that is away from the third airway 1231, and the fifth airway 1233 and the fourth airway 1232 are on the same plane. The third airway 1231 and the fifth airway 1233 are arranged perpendicularly, and the fifth airway 1233 is perpendicular to the plane formed by the fourth airway 1232 and the third airway 1231. That is to say, the fifth airway 1233 is parallel to the second airway 1222.
[0055] In some embodiments, please refer to the following: Figure 2 , Figure 3 and Figure 4 The first air passage 1221 and the third air passage 1231 extend perpendicularly to the first side wall of the valve body 1. The fourth air passage 1232 extends perpendicularly to the second side wall of the valve body 1. The fifth air passage 1233 extends perpendicularly to the side wall of the valve body 1 where the air outlet 121 is located. Both the first and second side walls are adjacent to the side wall of the valve body 1 where the air outlet 121 is located.
[0056] In this embodiment, the first sidewall can be as follows: Figure 2 The valve body 1 shown is the top wall. The second side wall can be as follows: Figure 2 and Figure 3 The side wall of the valve body 1 between the exhaust valve mounting part 2 and the air outlet 121 is shown. The side wall of the valve body 1 where the air outlet 121 is located can be as follows: Figure 4 The sidewall shown is adjacent to both the first and second sidewalls. It should be noted that the extension direction of the second air passage 1222 is also perpendicular to the sidewall of the valve body 1 where the air outlet 121 is located. This helps to ensure that the air passages are perpendicular to each other within the valve body 1, increasing the complexity of the bends of the first passage 122 and the second passage 123 within the valve body 1, and further increasing the difficulty for water droplets or impurities to enter the exhaust valve mounting part 2 from the air outlet 121.
[0057] Furthermore, multiple air holes 14 are provided on the side wall of the valve body 1. The air holes 14 are respectively connected to the first air passage 1221 and the third air passage 1231 on the first side wall, the fourth air passage 1232 on the second side wall, the second air passage 1222 on the side wall of the valve body 1 where the exhaust valve mounting part 2 is located, and the fifth air passage 1233 on the side wall of the valve body 1 where the air outlet 121 is located. A plug is provided inside the air hole 14.
[0058] Specifically, the air holes 14 correspond one-to-one with the first air passage 1221, the second air passage 1222, the third air passage 1231, the fourth air passage 1232, and the fifth air passage 1233. That is, by opening two air holes 14 along a direction perpendicular to the first sidewall, the first air passage 1221 and the third air passage 1231 can be formed respectively. The first air passage 1221 is connected to the exhaust valve mounting part 2 and is used to connect to the exhaust valve outlet 121. A vent 14 is opened in the direction of the side wall to form a second air passage 1222 connecting the first air passage 1221 and the third air passage 1231; a vent 14 is opened in the direction perpendicular to the second side wall to form a fourth air passage 1232 connecting the third air passage 1231; a vent 14 is opened in the direction perpendicular to the side wall of the valve body 1 where the air outlet 121 is located, that is, in the air outlet 121, to form a fifth air passage 1233 connecting the fourth air passage 1232. After the vents 14 are opened, they can be blocked by a plug to make the first air passage 1221 and the second air passage 1222 form a closed first channel 122, and the third air passage 1231, the fourth air passage 1232 and the fifth air passage 1233 form a closed second channel 123.
[0059] In some other embodiments, see Figure 1 The valve body 1 also has a booster mounting section 3 and an air tank connection port 4 (RES). The valve body 1 also has a booster chamber 13 connecting both sides of the booster mounting section 3, used to connect an air spring, so that the booster can pump compressed air through the booster chamber 13 into the air spring. The air tank connection port 4 is located on the side wall of the valve body 1 where the air outlet 121 is located. The air tank connection port 4 communicates with the booster chamber 13 on one side of the booster mounting section 3, so that the booster can pump compressed air through the booster chamber 13 and into the air tank through the air tank connection port 4.
[0060] In some other embodiments, the valve body 1 also has RR, RL, FR, and FL interfaces. The FL interface connects to the left front air spring or related components. By controlling the opening and closing of this interface with a connected solenoid valve, the inflation or deflation of the left front air spring can be adjusted, thereby achieving automatic adjustment of the left front vehicle height. The FR interface connects to the right front air spring or related components. By controlling the opening and closing of this interface with a connected solenoid valve, the air pressure of the right front air spring can be adjusted to maintain the right front vehicle height within a set range. The RL interface connects to the left rear air spring or related components. By controlling the opening and closing of this interface with a connected solenoid valve, the inflation or deflation of the left rear air spring can be achieved, maintaining the left rear vehicle height stability. The RR interface connects to the right rear air spring or related components. By controlling the opening and closing of this interface with a connected solenoid valve, the right rear air spring receives appropriate air pressure, ensuring the right rear vehicle is at a set height.
[0061] An embodiment of this utility model also provides an air suspension, see reference. Figure 5 , Figure 5 This is a schematic diagram of a structure for an air suspension provided in this embodiment. It includes the aforementioned valve block structure, a controller, an air tank, a motor, and an air pump and an exhaust valve mounted on the valve block structure. The controller controls the operation of the motor and the exhaust valve. The motor drives the air pump to pressurize outside air and pump it into the air tank or air spring.
[0062] exist Figure 5 AF is the air filter (connected to the air inlet 111 of the valve block structure); AV1-AV are air valves; EV is the exhaust valve (connected to the air outlet 121 of the valve block structure); CM is the air compressor; SV1-4 are switching valves; AD is the air dryer; P / U is the pressure sensor; RES is the air tank; M is the motor; and ECU is the controller. FL, FR, RL, and RR (air springs) are connected to the FL, FR, RL, and RR interfaces in the valve block interface, respectively. The air tank is connected to the RES interface of the valve block interface. The exhaust valve is installed in the exhaust valve mounting section 2 of the valve body 1 structure, and the air compressor is installed in the booster mounting section 3 of the valve body 1 structure.
[0063] Specifically, the controller uses pressure sensor data to control the motor to drive the air compressor, drawing air from the atmosphere, filtering it through AF, pressurizing it through CM, and then delivering it to AD for drying before it enters the storage tank or directly passes through valve AV to FL, FR, RL, and RR. It should be noted that there is a one-way valve between AF and CM, with the flow direction from AF to CM. There is an EV between CM and AD, and the air is discharged from outlet 121 after being controlled by the EV. A one-way valve and a throttle valve are installed between AD and SV1 and SV4. The one-way valve flows from AD to SV4, and the throttle valve accelerates from SV1 and SV4 to AD.
[0064] In normal operating mode, SV4 or SV1 opens, allowing air dried by AD to enter the air tank via SV4, or to enter FL, FR, RL, and RR via SV1. In exhaust mode, RES gas passes through SV4, is accelerated by the throttle valve next to the check valve, and is finally discharged through the EV valve after being dried by AD. In other modes, FL, FR, RL, and RR gas passes through SV2, or RES gas passes through SV3, is pressurized by CM, and is discharged to the atmosphere via EV.
[0065] It should be noted that, Figure 5 The line connecting the EV is the first channel 122 and the second channel 123 of the improved valve block structure described above.
[0066] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
