Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] The air pump 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0023] Optionally, the air pump 100 according to embodiments of the present invention can be used to supply air to an air-using device, which may include at least one of an air suspension system, an oxygen generation system, an air pressure braking system, a seat air supply system, and a tire inflation and pressure maintenance system. The air suspension system is a key active suspension technology for improving vehicle comfort, handling, and passability, and the air pump 100 is the core power source of the air suspension system. The seat air supply system may include at least one of a massage device, a lumbar support, a leg rest, and seat side wings.

[0024] like Figures 1-6 As shown, an air pump 100 according to an embodiment of the present invention includes: an integrated base 10, a frameless motor 20, and a compression structure 30.

[0025] Specifically, the integrated base 10 has a first mounting cavity 11, a second mounting cavity 12, and a flow channel 13; the frameless motor 20 is mounted in the first mounting cavity 11 and includes a stator assembly 21 and a rotor assembly 22; the compression structure 30 is mounted in the second mounting cavity 12 and is drively connected to the rotor assembly 22. The compression structure 30 is configured to move under the drive of the rotor assembly 22 and drive the gas flow in the flow channel 13.

[0026] Optionally, such as Figures 2-4 As shown, the frameless motor 20 can be a brushless motor. Compared with brushed motors, brushless motors have no mechanical commutation wear, longer service life, lower noise during operation, and higher air pumping efficiency. Furthermore, brushless motors do not have mechanical contact during current commutation, resulting in significantly less magnetic field radiation than brushed motors. Both the stator core of the stator assembly 21 and the rotor core of the rotor assembly 22 are made of cold-rolled silicon steel sheets. Square holes are provided on the rotor core for pressing in magnetic steel sheets, giving the entire assembly magnetism and creating a fixed-direction annular magnetic field. Openings on the stator core are used for winding stator windings, which, when energized, generate a continuously changing rotating magnetic field. When the brushless motor is working, the rotating magnetic field of the stator assembly 21 and the fixed magnetic field of the rotor assembly 22 directly generate electromagnetic torque, driving the rotor assembly 22 to rotate synchronously with the magnetic field, thus realizing the conversion of electrical energy into mechanical energy.

[0027] Optionally, such as Figure 4 and Figure 5 As shown, the compression structure 30 may include a crank connecting rod, piston, worm gear, or scroll moving disk and scroll stationary disk, etc.

[0028] The rotor assembly 22 can be directly connected to the compression structure 30, or indirectly connected through transmission components such as transmission gears and transmission rods. The rotation of the rotor assembly 22 of the frameless motor 20 provides power for the movement of the compression structure 30, which in turn compresses the gas to drive the gas flow within the flow channel 13.

[0029] Here, there can be one or more flow channels 13. Flow channels 13 can connect different components such as valve bodies 50, compression structures 30, dryers 70, gas storage 91, and gas-using devices. For example, flow channel 13 can be connected to a gas-using device to supply gas to the gas-using device; or flow channel 13 can be connected to a gas storage 91 to temporarily store compressed gas in the gas storage 91.

[0030] In related technologies, a pneumatic valve block has a channel for gas flow, a compression component is located within the pneumatic valve block, and a motor includes a housing and a stator and rotor housed within the housing; the motor is fixed to one side of the pneumatic valve block by bolts. In the above structure, the motor is the main source of noise, and its vibration amplitude is large during operation, resulting in high overall operating noise, poor NVH performance, and a large number of parts, which is not conducive to reducing costs, size, and weight.

[0031] In the embodiments of this application, such as Figures 1-5As shown, the frameless motor 20 and the compression structure 30 are respectively installed in the first mounting cavity 11 and the second mounting cavity 12 of the integrated base 10. The integrated base 10 serves as both the motor housing and the flow path. Compared with the air pump in the related art, the motor housing and the structure of fixing the motor with bolts are eliminated. The rotor assembly 22 and the stator assembly 21 can be directly installed in the integrated base 10, for example, by heating and pressing.

[0032] Compared to the motor housing, the integrated base 10 has a thicker overall wall due to the integrated flow channel 13, resulting in better sound insulation. This effectively reduces the outward transmission of the main noise source, the frameless motor 20, thereby reducing the overall operating noise of the air pump 100.

[0033] The frameless motor 20 is arranged inside the integrated base 10, rather than installed on the outside of the integrated base 10. This allows the frameless motor 20 to be closer to the overall center of gravity, and the vibration generated by the frameless motor 20 during operation has a smaller impact on the overall structure, which can significantly reduce vibration problems during the inflation process.

[0034] The inner wall of the integrated base 10 serves both as a support and a motor housing, and can also reduce the number of parts and the motor mounting structure, thereby reducing costs, size and weight.

[0035] According to an embodiment of the present invention, the air pump 100 is integrated and installed in the integrated base 10 by means of the frameless motor 20 and the compression structure 30. This can effectively reduce the vibration amplitude of the frameless motor 20 in the working state and reduce the transmission of working noise, thereby reducing the working noise of the product, improving NVH performance, and at the same time reducing the number of parts, reducing costs, shrinking the size and reducing weight.

[0036] In some embodiments of the present invention, such as Figure 4 As shown, in the direction perpendicular to the axis of the frameless motor 20, the minimum distance between the inner circumferential surface of the first mounting cavity 11 and the outer circumferential surface of the integrated base 10 is greater than or equal to 15mm. This ensures that the integrated base 10 has sufficient wall thickness to accommodate the flow channel 13, and that the wall thickness of the integrated base 10 is sufficiently large to provide good sound insulation.

[0037] In some embodiments, continue to refer to Figure 4 As shown, at least a portion of the flow channel 13 is located between the inner circumferential surface of the first mounting cavity 11 and the outer circumferential surface of the integrated base 10, and the minimum distance between the flow channel 13 and the inner circumferential surface of the first mounting cavity 11 is greater than or equal to 2mm. This ensures the structural strength of the joint between the integrated base 10 and the frameless motor 20, and also ensures the wall thickness at the joint with the frameless motor 20, thereby achieving good sound insulation.

[0038] According to some embodiments of the present invention, such as Figure 1, Figure 2 and Figure 4 As shown, the air pump 100 also includes a control component 40, which is located on the side of the frameless motor 20 away from the compression structure 30 in the axial direction of the frameless motor 20.

[0039] The control component 40 can be used to control the working state of the air pump 100. For example, components such as the stator assembly 21 and the valve body 50 can be connected to the control component 40 so that the energization state of the stator assembly 21 and the conduction state of the valve body 50 can be controlled by the control component 40.

[0040] In the above embodiment, the control component 40 and the compression structure 30 are respectively disposed on both axial sides of the frameless motor 20, and the integrated base 10 is disposed at least on the radial outer periphery of the frameless motor 20, so that the control component 40, the compression structure 30 and the integrated base 10 can completely enclose the frameless motor 20. The noise emitted by the frameless motor 20 when it is powered on is soundproofed by the control component 40, the compression structure 30 and the integrated base 10 before it is transmitted out, which can greatly reduce the noise of the product.

[0041] In some embodiments, such as Figure 2 , Figure 4 and Figure 6 As shown, the integrated base 10 includes a base body 14 and a cover plate 15. The base body 14 defines a first mounting cavity 11, and the first mounting cavity 11 has an opening facing the control component 40. The cover plate 15 seals the opening of the first mounting cavity 11, and the control component 40 is located on the side of the cover plate 15 facing away from the frameless motor 20.

[0042] During assembly, the frameless motor 20 can be first installed into the first mounting cavity 11 through the cavity opening, then the cover plate 15 can be placed over the cavity opening of the first mounting cavity 11, and finally the control component 40 can be installed on the side of the cover plate 15 facing away from the frameless motor 20, making the assembly of components such as the frameless motor 20 and the control component 40 convenient. Furthermore, because the cover plate 15 seals the cavity opening of the first mounting cavity 11, gas inside the first mounting cavity 11 will not leak through the cavity opening, thereby preventing any impact on the air pump 100's pumping capacity.

[0043] Furthermore, since a portion of the integrated base 10 can be located between the frameless motor 20 and the control component 40, i.e., the cover plate 15 is located between the frameless motor 20 and the control component 40, the operating noise of the frameless motor 20 can be transmitted through the two layers of sound insulation of the cover plate 15 and the control component 40, which can further reduce the noise of the product.

[0044] In some embodiments of the present invention, such as Figure 2 and Figure 6 As shown, the integrated base 10 has a plurality of valve bodies 50 on the side facing the control component 40, and the valve bodies 50 are used to control the opening and closing of the flow channel 13.

[0045] For example, valve body 50 may include exhaust valve 52, intake valve 53, safety valve 51, etc. By controlling the opening and closing of flow channel 13 through valve body 50, functions such as starting and stopping air pump 100 and switching modes can be realized. In the above embodiment, the distance between valve body 50 and control component 40 is relatively close, which facilitates the electrical connection between valve body 50 and control component 40.

[0046] It is worth noting that all valve bodies 50 of the air pump 100 can be evenly located on the side of the integrated base 10 facing the control component 40, or partially located on the side of the integrated base 10 facing the control component 40. For example, some valve bodies 50 are solenoid valves, which are located on the side of the integrated base 10 facing the control component 40 and connected to the control component 40. Other valve bodies 50 (such as the intake valve 53) are non-energized valves such as check valves, which can be located on the side of the integrated base 10 facing the control component 40, or on the side of the integrated valve perpendicular to the axis of the frameless motor 20.

[0047] In some embodiments of the present invention, such as Figure 2 and Figure 6 As shown, a sensor 60 is provided on the side of the integrated base 10 facing the control component 40. The sensor 60 is connected to the flow channel 13 and is used to detect the temperature and / or pressure of the gas in the flow channel 13.

[0048] The conduction state of the flow channel 13, such as on / off state or opening degree, can be controlled based on the detection results of the sensor 60, making the air pump 100 work more stably and safely. For example, the sensor 60 can be a pressure sensor. When the pressure sensor detects that the pressure in the flow channel 13 exceeds the safety threshold, it can control the flow path connected to the outside to achieve rapid pressure relief.

[0049] In the above embodiments, the sensor 60 and the control component 40 are close to each other, which facilitates the electrical connection between the sensor 60 and the control component 40.

[0050] According to some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the air pump 100 also includes a dryer 70, at least one flow channel 13 is connected to the dryer 70, and the dryer 70 is located on one side of the integrated base 10 in the axial direction of the frameless motor 20.

[0051] The dryer 70 can remove impurities from the gas flowing through the flow channel 13, such as by drying the gas, or it can be used to remove unwanted components from the gas. For example, in an embodiment where the air pump 100 is used in an oxygen generator, the dryer 70 can be used to remove nitrogen from the gas to increase the oxygen concentration.

[0052] When it is necessary to regenerate the dryer 70, the gas can also be slowly and for a long time introduced into the dryer 70 through the flow channel 13 to achieve the regeneration of the dryer 70.

[0053] The air pump 100 generates heat during operation, for example, from the movement of the compression structure 30 or the power supply to the frameless motor 20. This heat can be radiated outward through the integrated base 10. By placing the dryer 70 on one side of the integrated base 10, the heat from the integrated base 10 can radiate to the dryer 70, thereby improving the dryer 70's impurity removal efficiency and regeneration efficiency.

[0054] In some embodiments, such as Figure 1 and Figure 2 As shown, there are multiple dryers 70 (i.e., two or more), and these multiple dryers 70 are connected in parallel. By setting multiple dryers 70 in parallel, the effective drying area can be increased, and the drying efficiency can be improved.

[0055] In some embodiments, such as Figure 1 and Figure 2 As shown, the integrated base 10 has a receiving groove 16 at one end of the frameless motor 20 in the axial direction. The receiving groove 16 and the compression structure 30 are arranged perpendicular to the axial direction of the frameless motor 20. The dryer 70 is located in the receiving groove 16.

[0056] In at least one direction perpendicular to the axis of the frameless motor 20, the size of the compression structure 30 is generally smaller than that of the frameless motor 20. By arranging the receiving groove 16 and the compression structure 30 perpendicular to the axis of the frameless motor 20, and placing the dryer 70 in the receiving groove 16, the dryer 70 and the compression structure 30 can be arranged perpendicular to the axis of the frameless motor 20. The dryer 70 can make full use of the space on the side of the compression structure 30 with the smaller size, making the overall structure of the air pump 100 more compact and smaller in size, and reducing the volume and material usage of the integrated base 10, thereby reducing costs and weight.

[0057] For example Figure 4 and Figure 5As shown, the compression structure 30 includes two pistons arranged in a first direction perpendicular to the axial direction of the frameless motor 20 and capable of reciprocating along this direction to achieve gas compression. A second direction perpendicular to the axial direction of the frameless motor 20 is perpendicular to the first direction. The dimension of the compression structure 30 along the second direction is smaller than its dimension along the first direction. The dryer 70 can be located on one side of the compression structure 30 in the second direction to fully utilize the space therein. This ensures that the overall dimension of the air pump 100 in the second direction remains approximately the same as the dimension of the integrated base 10 in the second direction after the dryer 70 is installed, resulting in a compact overall structure for the air pump 100. Furthermore, by providing the receiving groove 16, the wall thickness of the integrated base 10 at the compression structure 30 is more uniform, and the material used for the receiving groove 16 is eliminated, thus reducing costs and weight.

[0058] In some specific embodiments, reference is made to Figure 1 and Figure 2 As shown, there are multiple receiving grooves 16, with at least two receiving grooves 16 located on both sides of the compression structure 30 perpendicular to the axial direction of the frameless motor 20.

[0059] Multiple receiving grooves 16 can accommodate multiple dryers 70, which are used to remove impurities from the gas within the flow channel 13, thereby improving the impurity removal efficiency and effect. Furthermore, at least two dryers 70 can be located on either side of the compression structure 30 perpendicular to the axial direction of the frameless motor 20, for example, on either side of the compression structure 30 in the second direction, which further improves space utilization and structural compactness. Moreover, both dryers 70 can be positioned close to the compression structure 30, resulting in a more uniform heat transfer from the compression structure 30 to the two dryers 70, effectively enhancing both the impurity removal effect and regeneration efficiency of the two dryers 70.

[0060] In some embodiments, such as Figure 2 As shown, the integrated base 10 has air nozzle connectors 17 on both sides perpendicular to the axial direction of the frameless motor 20, and at least one flow channel 13 is connected to the air nozzle connector 17.

[0061] The air nozzle connector 17 can be used to connect the air pump 100 to other components, such as air-using devices or gas storage devices 91, to achieve air passage communication between the air pump 100 and other components. For example, the rear side of the integrated base 10 is provided with an air nozzle connector 17 for connecting to the gas storage device 91 and part of the air-using device (such as the rear air suspension 93 of the vehicle), and the front side of the integrated base 10 is provided with an air nozzle connector 17 for connecting to another part of the air-using device (such as the front air suspension 92 of the vehicle).

[0062] In the above embodiment, the air nozzle connector 17 is located on both sides of the integrated base 10 perpendicular to the axial direction of the frameless motor 20, and the dryer 70 is located on both sides of the integrated base 10 along the axial direction of the frameless motor 20. Thus, the air nozzle connector 17 and the dryer 70 can be located on different sides of the integrated base 10, thereby making full use of the space on different sides of the integrated base 10, improving the overall structural compactness, and avoiding interference between the pipeline components connected to the air nozzle connector 17 and the dryer 70.

[0063] According to some embodiments of the present invention, such as Figure 1 and Figure 4 As shown, a shielding layer 80 is provided between the cavity wall of the first mounting cavity 11 and the frameless motor 20.

[0064] The shielding layer 80 can be a coating or component with magnetic field shielding function, such as an iron hoop. By setting the shielding layer 80, the influence of the magnetic field radiation of the frameless motor 20 can be reduced, making it less likely for the magnetic field of the frameless motor 20 to affect the performance of surrounding components such as solenoid valves.

[0065] In some embodiments, such as Figure 4 As shown, the shielding layer 80 is a cylindrical structure and is located between the outer peripheral surface of the frameless motor 20 and the inner peripheral wall of the first mounting cavity 11. The shielding layer 80 has a first through hole 801 that penetrates radially through the frameless motor 20. The integrated base 10 has a second through hole 19 that is opposite to the first through hole 801. The fastener 18 passes through the second through hole 19 and the first through hole 801 and abuts against the outer peripheral surface of the frameless motor 20 (such as the outer peripheral surface of the stator assembly 21) to limit the positioning of the integrated base 10, the shielding layer 80 and the frameless motor 20, while minimizing the impact on the electromagnetic structure of the frameless motor 20.

[0066] A vehicle according to an embodiment of the present invention includes an air pump 100 according to an embodiment of the present invention. Since the air pump 100 according to an embodiment of the present invention has the aforementioned beneficial technical effects, the vehicle according to an embodiment of the present invention, by integrating the frameless motor 20 and the compression structure 30 within the integrated base 10, can effectively reduce the vibration amplitude of the frameless motor 20 during operation and reduce the transmission of operating noise, thereby reducing product operating noise, improving NVH performance, while simultaneously reducing the number of parts, lowering costs, shrinking size, and reducing weight.

[0067] The following describes a vehicle according to a specific embodiment of the present invention in detail with reference to the accompanying drawings. It is to be understood that the following description is merely illustrative and should not be construed as limiting the invention.

[0068] like Figures 1-12As shown, a vehicle according to a specific embodiment of the present invention includes an air pump 100, a gas storage 91, and an air dispensing device. The air dispensing device includes two front air suspensions 92 (left front air suspension FL and right front air suspension FR) and two rear air suspensions 93 (left rear air suspension RL and right rear air suspension RR). The air pump 100 includes an integrated base 10, a compression structure 30, a frameless motor 20, a control assembly 40, multiple valve bodies 50, a sensor 60, a dryer 70, and a shielding layer 80. The integrated base 10 has a first mounting cavity 11, a second mounting cavity 12, and multiple flow channels 13. A frameless motor 20 and a compression structure 30 are arranged along the motor axis and respectively installed in the first mounting cavity 11 and the second mounting cavity 12. A shielding layer 80 is disposed between the outer periphery of the frameless motor 20 and the inner circumferential surface of the first mounting cavity 11. A control component 40 and a dryer 70 are respectively disposed on both sides of the integrated base 10 along the motor axis and are respectively located close to the frameless motor 20 and the compression structure 30. Multiple valve bodies 50 include a safety valve 51, an exhaust valve 52, an intake valve 53, AV1, AV2, AV3, AV4, SV1, SV2, SV3, and SV4. The connection relationships of each valve body 50, component, and flow channel 13 are as follows: Figures 7-12 As shown.

[0069] The vehicle features a body raising mode, a body lowering mode, a gas storage 91 open-type air replenishment mode, an air suspension open-type air replenishment mode, a dryer 70 regenerative exhaust mode, and an air suspension emergency exhaust mode.

[0070] like Figure 7 As shown, in the vehicle body lifting mode, SV1 and SV3 are open, SV2 and SV4 and exhaust valve 52 are closed, safety valve 51 is normally closed, and sensor 60 detects the gas pressure in flow channel 13; frameless motor 20 drives compression structure 30 to work, first opening AV1 and AV2 to inflate the front air suspension 92 from the gas storage 91, and after reaching a suitable height, closing AV1 and AV2 and opening AV3 and AV4 to inflate the rear air suspension 93 from the gas storage 91, finally completing the lifting of the entire vehicle body.

[0071] like Figure 8 As shown, in the vehicle descent mode, SV2 and SV4 are open, SV1, SV3 and exhaust valve 52 are closed, safety valve 51 is normally closed, and sensor 60 detects the gas pressure in flow channel 13; frameless motor 20 drives compression structure 30 to work, first opening AV1 and AV2 to release air from front air suspension 92, and after reaching a suitable height, closing AV1 and AV2 and opening AV3 and AV4 to release air from rear air suspension 93, finally completing the descent of the entire vehicle body.

[0072] like Figure 9As shown, in the open-type gas replenishment mode of the gas storage 91, SV1 and SV4 are open, AV1, AV2, AV3, AV4, SV2, SV3 and exhaust valve 52 are closed, safety valve 51 is normally closed, and sensor 60 detects the gas pressure in the flow channel 13; frameless motor 20 drives compression structure 30 to work, and gas is filled into the gas storage 91 from the outside atmosphere, finally completing the open-type gas replenishment of the gas storage 91.

[0073] like Figure 10 As shown, in the open-type air replenishment mode of the air suspension, SV1 is open, SV2, SV3, SV4 and exhaust valve 52 are closed, safety valve 51 is normally closed, and sensor 60 detects the gas pressure in flow channel 13; frameless motor 20 drives compression structure 30 to work, first opening AV1 and AV2 to inflate the front air suspension 92 from the outside atmosphere, and after reaching the appropriate pressure, closing AV1 and AV2 and opening AV3 and AV4 to inflate the rear air suspension 93 from the outside atmosphere, finally completing the open-type air replenishment of the air suspension.

[0074] like Figure 11 As shown, in the regeneration exhaust mode of dryer 70, SV1, SV4, and exhaust valve 52 are open, AV1, AV2, AV3, AV4, SV2, and SV3 are closed, safety valve 51 is normally closed, and sensor 60 detects the gas pressure in flow channel 13; frameless motor 20 drives compression structure 30 to work, so that the gas in storage gas 91 flows through dryer 70 and is discharged to the outside atmosphere, finally completing the regeneration exhaust of dryer 70.

[0075] like Figure 12 As shown, in the emergency exhaust mode of the air suspension, SV2, exhaust valve 52, and safety valve 51 are open, while SV1, SV3, and SV4 are closed. Sensor 60 detects the gas pressure in the flow channel 13, and the frameless motor 20 and compression structure 30 do not work. First, AV1 and AV2 are opened to exhaust the front air suspension 92 to the outside atmosphere. After the pressure reaches a safe value, AV1 and AV2 are closed and AV3 and AV4 are opened to exhaust the rear air suspension 93 to the outside atmosphere, thus completing the emergency exhaust process of the air suspension.

[0076] In the above embodiment, the air pump 100 no longer mounts the motor separately outside the pneumatic valve block. Instead, the integrated base 10 simultaneously supports and mounts the compression structure 30 and the frameless motor 20, and also serves as the motor housing. This reduces the number of parts, resulting in lower costs and a lighter product. This structural arrangement places the frameless motor 20 closer to the center of gravity of the air pump 100, minimizing the impact of vibrations generated by the frameless motor 20 during operation and significantly improving vibration issues during inflation. This structural arrangement places the main noise source of the product, the frameless motor 20, inside the integrated base 10 and between the control component 40 and the compression structure 30. After product assembly, the frameless motor 20 is completely enclosed within the product. The noise emitted during operation is insulated by the integrated base 10 and the control component 40 before being transmitted, significantly reducing product noise.

[0077] The air pump 100 and other components and operation of the vehicle according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
