Abstract
Description
Technical Field
[0001] This disclosure relates to a vehicle-mounted inflation system and a vehicle. Background Technology
[0002] Some vehicles (such as large buses, heavy-duty trucks, and luxury cars) have chassis equipped with air suspension. The air springs in the air suspension can be inflated by an air pump installed in the chassis. In some related technologies, the installation between the air pump and the chassis can reduce the transmission of vibration from the air pump to the vehicle interior through a two-stage vibration isolation assembly. Utility Model Content
[0003] Research has revealed that single-stage vibration isolation has 6 rigid body modal points, while dual-stage vibration isolation has as many as 12 rigid body modes. Neither single-stage nor dual-stage vibration isolation can prevent the air pump from resonating with the rigid body modes during the increase of its operating speed. This limits the operating speed range of the air pump. Moreover, the vibration isolation system cannot actually reduce the vibration and noise radiation of the pump body. This increases the vibration and noise inside the vehicle, affecting the comfort of the occupants and the durability and lifespan of some dual-stage vibration isolation components that use vibration isolation rubber.
[0004] In view of this, the present disclosure provides an on-board inflation system and a vehicle that can improve vehicle vibration reduction.
[0005] In one aspect of this disclosure, an on-board inflation system is provided for a vehicle, comprising: an air compressor; a mounting structure including at least one primary vibration isolation component, the air compressor being mounted to the vehicle via the mounting structure; and at least one medium energy dissipation damper disposed in at least one of the air compressor and the mounting structure.
[0006] In this embodiment, the air compressor is installed on the vehicle via an installation structure and is isolated by at least one vibration isolation component in the installation structure. By setting at least one medium energy dissipation damper in at least one of the air compressor and the installation structure, the vibration amplitude of the resonance point of the vibration isolation component can be reduced by medium energy dissipation, thereby reducing the vibration of the vehicle inflation system and reducing the vibration and noise transmitted from the vehicle inflation system to the vehicle. This improves the comfort of the occupants and helps to broaden the operating speed range of the air compressor and improve the durability and lifespan of the vibration isolation component.

[0012] In this embodiment, the first vibration isolation component and the second vibration isolation component together have 12 rigid body modal points.

[0017] In some embodiments, the air compression device includes a cylinder, and the at least one medium energy dissipation damper includes a medium energy dissipation damper bonded to the arcuate outer wall of the cylinder.

The medium energy dissipation damper can be configured as a conformal damper, that is, its housing containing internal media such as particles is made with a surface that matches the arc-shaped outer wall of the cylinder, thereby forming a large-area adhesive fixation with the cylinder to better dissipate the vibration energy of the cylinder.
[0019] In some embodiments, the at least one medium energy-consuming damper includes a medium energy-consuming damper that is bonded to or fixedly connected to a portion of the air compression device other than the cylinder body via a connector.
[0020] In this embodiment, by bonding and fixing the parts of the air compressor other than the cylinder body or by fixing the medium energy dissipation damper through the connector, the medium energy dissipation damper can dissipate the vibration of different parts of the air compressor.

The dielectric energy-dissipating damper can be disposed at the end of each vibration-isolating rubber bushing, or at the ends of a subset of the bushings. Furthermore, adhesive bonding facilitates the connection of the dielectric energy-dissipating damper to a relatively small surface area of the vibration-isolating rubber bushing.
[0025] In some embodiments, the at least one dielectric energy-dissipating damper includes a dielectric energy-dissipating damper that is bonded to or fixed by a connector to at least one surface of the upper and lower surfaces of the adapter bracket.

[0056] In some related technologies, the installation between the air pump and the chassis can reduce the transmission of vibration from the air pump to the vehicle interior through a two-stage vibration isolation assembly.
[0057] Research has revealed that single-stage vibration isolation has 6 rigid body modal points, while dual-stage vibration isolation has as many as 12 rigid body modes. Neither single-stage nor dual-stage vibration isolation can prevent the air pump from resonating with the rigid body modes during the increase of its operating speed. This limits the operating speed range of the air pump. Moreover, the vibration isolation system cannot actually reduce the vibration and noise radiation of the pump body. This increases the vibration and noise inside the vehicle, affecting the comfort of the occupants and the durability and lifespan of some dual-stage vibration isolation components that use vibration isolation rubber.
[0058] In view of this, the present disclosure provides an on-board inflation system and a vehicle that can improve vehicle vibration reduction.
[0059] In one aspect of this disclosure, an on-board inflation system is provided for a vehicle, comprising: an air compressor; a mounting structure including at least one primary vibration isolation component, the air compressor being mounted to the vehicle via the mounting structure; and at least one medium energy dissipation damper disposed in at least one of the air compressor and the mounting structure.
[0060] In this embodiment, the air compressor is installed on the vehicle via an installation structure and is isolated by at least one vibration isolation component in the installation structure. By setting at least one medium energy dissipation damper in at least one of the air compressor and the installation structure, the vibration amplitude of the resonance point of the vibration isolation component can be reduced by medium energy dissipation, thereby reducing the vibration of the vehicle inflation system and reducing the vibration and noise transmitted from the vehicle inflation system to the vehicle. This improves the comfort of the occupants and helps to broaden the operating speed range of the air compressor and improve the durability and lifespan of the vibration isolation component.
[0061] Figure 1 This is a structural schematic diagram of some embodiments of the vehicle according to the present disclosure. (Reference) Figure 1 The vehicle 40 provided in this embodiment includes an on-board inflation system 41.
[0062] Vehicle 40 includes, but is not limited to, fuel-powered vehicles, natural gas vehicles, or new energy vehicles. New energy vehicles can be pure electric vehicles, hybrid vehicles, or range-extended vehicles, etc. Vehicles can be commercial vehicles, engineering vehicles, special vehicles, or private vehicles.
[0063] The vehicle-mounted inflation system 41 can be used to inflate components of the vehicle 40. It is mounted on the vehicle 40 and can move as the vehicle 40 travels.
[0064] In some embodiments, the vehicle 40 further includes a chassis 42 and an air spring 43. The air spring 43 is disposed on or integrally disposed with the chassis 42. The on-board inflation system 41 is disposed on or integrally disposed with the chassis 42 and is used for inflating the air spring 43.
[0065] Air spring 43 can be used in the pneumatic suspension of vehicle 40 to achieve the functions of shock absorption and improvement of vehicle driving performance. Chassis 42 can be an assembled chassis or an integrated chassis. Air spring 43 can be independent of chassis 42 and mounted on chassis 42, or it can be integrated with chassis 42.
[0066] The on-board inflation system 41 can be used to inflate the air spring 43, as well as other components in the vehicle 40. The on-board inflation system 41 can be independent of the chassis 42 and mounted on the chassis 42, or it can be integrated with the chassis 42. In some embodiments, the on-board inflation system 41 can also be located on components in the vehicle 40 other than the chassis 42.
[0067] In some embodiments, the vehicle 40 may further include a power unit, which may be mounted on or integrated with the chassis 42.
[0068] Power components may include motors and battery assemblies. A battery assembly refers to a physical module comprising one or more battery cells to provide higher voltage and capacity. For example, the battery assembly mentioned in this disclosure may include battery modules or battery packs. Some battery assemblies may include a housing for encapsulating one or more battery cells or battery modules. The housing may reduce or prevent the influence of liquids or other foreign matter on the charging or discharging of the battery cells, which may be used to power the vehicle, for example, as the vehicle's operating power source. The vehicle may also include a controller for controlling the power supply from the battery cells to the motor, for example, for the vehicle's starting, navigation, and driving power requirements.
[0069] The enclosure can be mounted on a chassis or integrally formed with the chassis. The enclosure may have an opening for a cover. Individual battery cells may include lithium-ion rechargeable batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, etc.
[0070] A single battery cell may include a casing, electrode assemblies, and electrolyte. The casing is used to house the electrode assemblies and electrolyte. The casing can be made of steel, aluminum, or composite metals (such as a copper-aluminum composite casing).
[0071] The electrode assembly may include a first electrode and a second electrode with opposite polarities, and a separator disposed between the first electrode and the second electrode. In some embodiments, the first electrode is a positive electrode and the second electrode is a negative electrode. In other embodiments, the first electrode is a negative electrode and the second electrode is a positive electrode. During the charging and discharging of a single battery cell, active ions (e.g., lithium ions) repeatedly insert and extract between the positive and negative electrode. The separator, disposed between the positive and negative electrode, serves to prevent short circuits between the positive and negative electrodes while allowing active ions to pass through.
[0072] In some embodiments, the electrode assembly includes a main body. The main body can be a wound structure formed by winding a positive electrode, a negative electrode, and a separator, or a stacked structure formed by overlapping positive electrode, negative electrode, and a separator. One or more positive and negative electrode sheets can be provided respectively. As an example, multiple positive electrode sheets and multiple negative electrode sheets are alternately arranged along the electrode thickness direction.
[0073] As an example, a battery cell can be a cylindrical battery cell, a prismatic battery cell, a pouch battery cell, or a battery cell of other shapes. Prismatic battery cells include prismatic battery cells, blade-shaped battery cells, and multi-prismatic batteries, such as hexagonal prismatic batteries.
[0074] Figure 2 These are schematic diagrams illustrating the structure of some embodiments of the vehicle-mounted inflation system according to this disclosure. (See reference...) Figure 1 and Figure 2 This disclosure provides an on-board inflation system 41 for a vehicle 40. The on-board inflation system 41 includes an air compressor 10, a mounting structure 20, and at least one medium energy-dissipating damper 30. The mounting structure 20 includes at least one stage of vibration isolation assembly 21, and the air compressor 10 is mounted to the vehicle 40 via the mounting structure 20. At least one medium energy-dissipating damper 30 is disposed at least one of the air compressor 10 and the mounting structure 20.
[0075] The air compression device 10 can perform operations such as inflation by compressing air, and may include an air compressor or air pump. The air compression device 10 may use compression units such as pistons and screws to realize the intake, compression and discharge of air. As the compression unit operates, the air compression device 10 will generate vibration and noise, which will be transmitted to the vehicle's cabin through the mounting structure 20.
[0076] The mounting structure 20 enables the air compressor 10 to be installed on the vehicle 40, and isolates and absorbs some of the vibration energy of the air compressor 10 through at least one level of vibration isolation component 21, thereby reducing vibration and noise in the cabin.
[0077] A medium-dissipating damper 30 refers to a damper that utilizes the physical properties of its internal medium to dissipate vibration energy and achieve vibration reduction. For example, vibration energy can be dissipated through the internal friction or viscosity of liquid or solid particles within the damper. The medium-dissipating damper 30 may include particle dampers, tuned liquid dampers, or viscous dampers, etc.
[0078] The energy dissipation capacity of the dielectric energy dissipation damper 30 can vary with the vibration intensity of the vibrating object to which it is installed. Generally, as the vibration intensity increases, the dielectric energy dissipation damper 30 dissipates more energy accordingly. Thus, as the vibration intensity of the vibrating object changes, the dielectric energy dissipation damper 30 can effectively reduce the vibration of the vibrating object by dissipating vibration energy.
[0079] The medium energy-dissipating damper can be installed only in the air compression device 10, only in the mounting structure 20, or both in the air compression device 10 and the mounting structure 20. The vehicle-mounted inflation system 41 may include one medium energy-dissipating damper 30 installed in the air compression device 10 or the mounting structure 20, or it may include multiple medium energy-dissipating dampers 30. These multiple dampers 30 may all be installed in the air compression device 10 or the mounting structure 20, or some of the dampers 30 may be installed in the air compression device 10, and others in the mounting structure 20.
[0080] In this embodiment, the air compressor 10 is installed on the vehicle 40 via the mounting structure 20, and is isolated by at least one vibration isolation component 21 in the mounting structure 20. By setting at least one medium energy dissipation damper in at least one of the air compressor 10 and the mounting structure 20, the vibration amplitude of the resonance point of the vibration isolation component 21 can be reduced by medium energy dissipation, thereby reducing the vibration of the vehicle inflation system and reducing the vibration and noise transmitted from the vehicle inflation system to the vehicle 40. This improves the comfort of the occupants and helps to broaden the operating speed range of the air compressor 10 and improve the durability and lifespan of the vibration isolation component 21.
[0081] In some embodiments, the dielectric energy-dissipating damper 30 includes a particle damper.
[0082] A particulate damper is a device that fills the interior of a structure or hollow container with particulate material at a preset filling ratio. The particulate material can include metallic or non-metallic particles, which dissipate vibrational energy through friction or collision within the damper. When vibration causes relative motion between particles, friction and collision between particles increase, thereby dissipating more energy. The greater the vibration and the more intense the particle motion, the more energy is dissipated.
[0083] In this embodiment, the medium energy dissipation damper 30 adopts a particle damper, which can provide effective damping effect for the vibration of at least one of the air compression equipment 10 and the mounting structure 20 at different frequencies, effectively reducing the vibration and noise transmitted from the air compression equipment 10 to the vehicle, and can reduce the noise bandwidth. Moreover, the structure is easy to design and install flexibly, and is easy to maintain.
[0084] refer to Figure 2 In some embodiments, the mounting structure 20 further includes a tray 22 on which the air compressor 10 is mounted. The at least one vibration isolation assembly 21 includes a first vibration isolation assembly 211. The first vibration isolation assembly 211 is disposed between the air compressor 10 and the tray 22 to achieve the first level of vibration isolation for the vehicle-mounted inflation system 41.
[0085] The tray 22 has a disc body that supports and is fixedly connected to the air compressor 10. A first vibration isolation assembly 211 is disposed between the air compressor 10 and the tray 22. For a single-stage vibration isolation structure, the first vibration isolation assembly 211 achieves single-stage vibration isolation; for a multi-stage vibration isolation structure, the first vibration isolation assembly 211 is used to achieve the first stage of vibration isolation for the vehicle-mounted inflation system 41. The first vibration isolation assembly 211 may include one or more vibration isolation elements, such as vibration-damping rubber bushings, rubber pads, etc.
[0086] In this embodiment, the first vibration isolation component 211 has 6 rigid body modal points, and the vibration amplitude of the resonance points corresponding to the 6 rigid body modal points can be effectively reduced by the medium energy dissipation damper 30.
[0087] refer to Figure 2 In some embodiments, the mounting structure 20 further includes an adapter bracket 23, which is mounted on the vehicle 40, and the tray 22 is mounted on the adapter bracket 23. The at least one vibration isolation assembly 21 further includes a second vibration isolation assembly 212, which is disposed between the tray 22 and the adapter bracket 23 to achieve a second level of vibration isolation for the vehicle-mounted inflation system 41.
[0088] The bracket body of the adapter bracket 23 and the tray 22 can be connected via multiple connecting feet. The second vibration isolation assembly 212 may include one or more vibration isolation elements, such as vibration isolation rubber bushings, rubber pads, etc., which may be set at the connecting feet or other locations.
[0089] The second vibration isolation component 212 is disposed between the tray 22 and the adapter bracket 23 to achieve the second level of vibration isolation of the vehicle-mounted air inflation system 41. For a two-stage vibration isolation structure, the first vibration isolation component 211 is used to achieve the first level of vibration isolation of the vehicle-mounted air inflation system 41, while the second vibration isolation component 212 is used to achieve the second level of vibration isolation of the vehicle-mounted air inflation system 41. For a vibration isolation structure with three or more stages, the first vibration isolation component 211 and the second vibration isolation component 212 are used to achieve the first two stages of vibration isolation of the vehicle-mounted air inflation system 41.
[0090] In this embodiment, the first vibration isolation component 211 and the second vibration isolation component 212 have a total of 12 rigid body modal points. The vibration amplitude of the resonance points corresponding to the 12 rigid body modal points can be effectively reduced by the medium energy dissipation damper 30, which is beneficial to widening the operating speed range of the air compression equipment.
[0091] In some embodiments, the first vibration isolation component 211 includes a vibration isolation rubber bushing; and / or, the second vibration isolation component 212 includes a vibration isolation rubber bushing.
[0092] For the vehicle-mounted inflation system 41, the first vibration isolation component 211 may include a vibration isolation rubber bushing, or the second vibration isolation component 212 may include a vibration isolation rubber bushing. Alternatively, the first vibration isolation component 211 may include a vibration isolation rubber bushing and the second vibration isolation component 212 may include a vibration isolation rubber bushing.
[0093] In this embodiment, the vibration-damping rubber bushing has excellent vibration isolation characteristics and a simple structure that facilitates installation, replacement, and maintenance. Combined with the medium energy-dissipating damper 30, it can effectively reduce the vibration of the air compression equipment, decrease the stress / strain amplitude of the rubber bushing, and significantly improve the fatigue life of the rubber bushing.
[0094] refer to Figure 2 In some embodiments, the at least one medium energy-consuming damper 30 is bonded to or fixedly connected to at least one of the air compression device 10 and the mounting structure 20 via a connector cp.
[0095] Depending on the location of the medium energy dissipation damper 30, various fixing methods can be used to connect it. For locations with relatively flat surfaces, adhesive fixing can be used, such as on the cylinder surface of the air compressor 10, the upper or lower surface of the tray 22, etc. Alternatively, the medium energy dissipation damper 30 can be fixed in locations or components where it is not easy to install connectors, such as the support feet or vibration isolation components. For locations where it is convenient to install connectors cp, the medium energy dissipation damper 30 can be fixedly connected to at least one of the air compressor 10 and the mounting structure 20 through connectors cp.
[0096] In this embodiment, the medium energy dissipation damper 30 can be stably set in multiple locations by means of adhesive bonding or by means of connector cp.

(See reference...) Figures 2-9 In several embodiments of this disclosure, the dielectric energy-dissipating damper can be installed at different locations.

[0099] The cylinder body 11 is a component in the air compression device 10 used to house moving parts such as pistons or rotors, and it may include a cylindrical outer shell portion. The medium energy dissipation damper 30 can be configured as a conformal damper, that is, its housing containing internal media such as particles is made to have a surface that matches the arc-shaped outer wall of the cylinder body 11, thereby forming a large-area adhesive fixation with the cylinder body 11 in order to better dissipate the vibration energy of the cylinder body 11.
