Description

Technical Field

[0001] This utility model relates to the technical field of air compressor installation auxiliary devices, specifically an installation auxiliary structure for air compressors. Background Technology

[0002] The air compressor is a key component in the fuel cell engine system, responsible for providing sufficient air for the fuel cell stack reaction.

[0003] Currently, air compressors are typically suspended from the bottom of the system using brackets, and their weight is considerable. During production line installation, a tilting platform can be used to position them in a "desktop installation" state, making operation convenient. However, in after-sales or maintenance scenarios where the compressor is already installed on a vehicle, the system cannot be tilted, and the air compressor is suspended. In this situation, the operator must hold the air compressor with one hand while using the other to loosen or assemble bolts, which is not only difficult to operate but also poses a safety hazard of the equipment slipping from their hands or injuring them. Although existing technologies commonly use adapter brackets and shock-absorbing pads for fixation, they do not solve the problem of safe single-person assembly and disassembly in systems that cannot be tilted.

[0004] Therefore, there is an urgent need for an auxiliary structure that can enable temporary fixation and quick disassembly of air compressors in confined spaces.

[0005] A search revealed a Chinese patent document disclosing an adjustable mounting device for an automotive air compressor [Application No.: 202323509427.8, Publication No.: CN222114895U]. This device includes a base, a rotary drive component, a turntable, a swing drive mechanism, and a clamping assembly for mounting the air compressor. While this patent allows for quick connection and separation of the air compressor by driving a positioning plate with a screw thread, the U-shaped elastic band and the elastic snap-fit ​​structure of the limiting groove used in this invention make operation simpler in space-constrained after-sales maintenance scenarios. It eliminates the need for complex adjustment mechanisms, enabling temporary support and one-handed operation of the air compressor, significantly improving the safety and convenience of the assembly and disassembly process. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide an installation auxiliary structure for air compressors.

[0007] An installation auxiliary structure for an air compressor, characterized in that it comprises: The mounting base plate has a pair of parallel limiting grooves on its lower surface. The auxiliary installation mechanism is an integrally formed U-shaped elastic band. The middle part of the U-shaped elastic band is located below the mounting base plate, and the two sides extend upward in opposite directions. Near the mounting base plate, the band bends inward to form a pair of opposing L-shaped bending segments. The bent part of each L-shaped bending segment is inserted into the corresponding limiting groove, and the L-shaped bending segment and the limiting groove are engaged with each other.

[0008] Preferably, an adapter bracket is fixedly provided in the middle of the lower surface of the mounting base plate, and the adapter bracket is located between the pair of limiting grooves.

[0009] The above technical solution enables centralized transmission and stable support of the forces acting beneath the mounting base. By fixing the adapter bracket in the middle of the mounting base and positioning it between a pair of limiting grooves, the load transmitted from the air compressor to be installed is preferentially borne by the adapter bracket, reducing local deflection and eccentric loading of the mounting base, thereby improving the overall rigidity and installation stability of the entire installation auxiliary structure.

[0010] Specifically, this arrangement of the adapter bracket, centered between the limiting slots, creates a symmetrical support area centered on the adapter bracket beneath the mounting base plate. A pair of limiting slots are located on either side of the adapter bracket, providing lateral and positional constraints for the L-shaped bend of the auxiliary mounting mechanism. The adapter bracket not only bears the downward pressure but also, together with the mounting base plate, defines the installation space for fasteners or vibration damping components, creating a coordinated structural relationship in terms of load-bearing, limiting, and connection.

[0011] Preferably, the adapter bracket is fixedly connected to the lower surface of the mounting base plate, and a shock-absorbing pad is provided between the adapter bracket and the mounting base plate.

[0012] The above technical solution effectively buffers and isolates vibrations generated during air compressor operation while ensuring reliable installation connections. By installing vibration-damping pads between the mounting base plate and the adapter bracket, rigid contact between rigid components is avoided, reducing the direct transmission of vibrations and impacts to the mounting base plate and its components above. Furthermore, it reduces localized stress concentration and improves the structural stability of the installation auxiliary structure under long-term loads and alternating operating conditions.

[0013] Specifically, this structure, where vibration damping pads are positioned between the mounting base and the adapter bracket, allows vibrations generated by the air compressor during startup, shutdown, and high-frequency operation to be absorbed and attenuated first through the elastic deformation of the damping pads before being transmitted to the downstream support structure via the adapter bracket. The damping pads provide elastic buffering in the thickness direction and some displacement compensation in the planar direction, which helps reduce the risk of loosening at fastener connections, lowers noise and resonance caused by vibration, and thus improves the smoothness and reliability of the overall installation auxiliary structure.

[0014] Preferably, the L-shaped bending section includes a vertical section extending upward along the side of the U-shaped elastic band and a horizontal section extending into the limiting groove from the end of the vertical section along the extending direction of the limiting groove.

[0015] The above technical solution enables reliable positioning and stable connection of the auxiliary installation mechanism. By specifically defining the L-shaped bending section as a vertical section extending upward along the side of the U-shaped elastic band and a horizontal section extending into the limiting groove from the end of the vertical section along the direction of the limiting groove, the L-shaped bending section forms a clear bending profile in space. This ensures the insertion and engagement with the limiting groove, and also facilitates control of the insertion depth and snap-fit ​​position, thereby improving the stability of the fit between the components in the installation auxiliary structure.

[0016] Specifically, this L-shaped bending structure with a vertical and horizontal section arranges the vertical section along the side of the U-shaped elastic band to determine the height position of the L-shaped bending section relative to the U-shaped elastic band. The horizontal section extends into the groove along the extension direction of the limiting groove, utilizing its length and cross-sectional shape to fit the inner wall of the limiting groove. The bends at the vertical and horizontal sections form clear corner boundaries, allowing the L-shaped bending section to maintain its basic geometric shape under external forces, avoiding twisting or overturning that could cause it to dislodge from the groove. This ensures a more reliable connection between the U-shaped elastic band and the mounting base plate in the installed state.

[0017] Preferably, the middle part of the U-shaped elastic band is an arc-shaped support section, and the two side sections connected to the arc-shaped support section are arranged opposite to each other. The arc-shaped support section and the side sections together form an upward-facing U-shaped receiving space.

[0018] The above technical solution enables stable support and reliable positioning of the bottom of the air compressor body. By designing the middle section of the U-shaped elastic band as an arc-shaped support section, and having the side sections arranged opposite to each other together forming an upward-opening U-shaped receiving space, the bottom of the air compressor can be accommodated within a more closely fitting support contour. This increases the support contact area, reduces local stress concentration, and thus improves the load-bearing stability and anti-displacement capability of the installation auxiliary structure for the air compressor.

[0019] Specifically, this U-shaped receiving space, composed of an arc-shaped support section and two side sections, features an arc-shaped support section that forms a curved or polygonal near-arc surface contact with the bottom of the air compressor. The two side sections are positioned opposite each other on either side of the air compressor body, providing lateral constraint on the air compressor through lateral positioning. The upward-facing arrangement allows the air compressor to be placed into the U-shaped receiving space from top to bottom during installation. The arc-shaped support section provides upward support, while the side sections provide lateral constraint. Together, these three elements form a supporting and encircling structure for the bottom of the air compressor, ensuring clearer positioning and greater stability of the air compressor within the installation auxiliary structure.

[0020] Preferably, the U-shaped elastic band is formed by bending a strip, and the width direction of the strip is substantially perpendicular to the plane of the mounting base plate.

[0021] The above technical solution simplifies the forming process of the U-shaped elastic band while ensuring the overall structural strength and elastic performance. By bending a strip to form a U-shaped elastic band, it maintains a continuous cross-sectional shape in the length direction and uniform cross-sectional dimensions in the thickness and width directions. This facilitates obtaining a regular U-shaped profile and consistent elastic properties, thereby improving the shape stability and repeatability of the installation auxiliary structure during repeated installation and disassembly processes.

[0022] Specifically, this strip-shaped component is bent into a U-shape, and its width direction is basically perpendicular to the plane of the mounting base. This arrangement allows the U-shaped elastic strip to have a larger cross-sectional dimension in the height direction, which is used to bear the load and provide support from top to bottom. At the same time, it maintains a smaller thickness dimension in the direction parallel to the plane of the mounting base, which facilitates the arrangement of L-shaped bending sections within a limited space and their fitting with the limiting groove. This orientation of the strip's cross-sectional direction helps control the bending stiffness and overall profile of the U-shaped elastic strip, reduces torsional deformation, and allows it to maintain a stable U-shaped support shape under stress.

[0023] Preferably, when the U-shaped elastic band is in a free state, the distance between the two L-shaped bends is greater than the distance between the two limiting grooves; when the U-shaped elastic band is in an installed state, the distance between the two L-shaped bends matches the distance between the two limiting grooves, and the bends of each L-shaped bend are respectively accommodated in the corresponding limiting groove.

[0024] The above technical solution can form a set of dimensional fit relationships from free opening to installation compression in the structure. This allows the installation auxiliary mechanism to remain in an outward-opening state when not installed, and to achieve a stable snap-fit ​​in the installed state through the dimensional matching between the L-shaped bending sections on both sides and the limiting groove. This achieves a good balance between assembly convenience and connection reliability.

[0025] Specifically, when the U-shaped elastic band is in a free state, the distance between the two L-shaped bends is greater than the distance between the two limiting grooves, so that the U-shaped elastic band will not interfere with the mounting base plate and the limiting grooves when it unfolds naturally. When the U-shaped elastic band is pressed against the mounting base plate and the two L-shaped bends are aligned with the limiting grooves, the distance between the two L-shaped bends is elastically contracted to match the distance between the two limiting grooves. The bent part of each L-shaped bend extends into the corresponding limiting groove and is constrained by the groove wall, forming a clear snap-fit ​​relationship geometrically.

[0026] Compared with the prior art, the present invention has the following advantages: 1. This utility model provides reliable temporary support during the assembly and disassembly of an air compressor through the elastic engagement of a U-shaped elastic band and a limiting groove. This design eliminates the need for operators to continuously lift the heavy air compressor, freeing their hands for operations such as bolt tightening, significantly reducing the difficulty of single-person operation. In maintenance settings with limited space, this temporary fixing method ensures operational safety, improves work efficiency, and provides substantial convenience for on-site maintenance.

[0027] 2. This auxiliary structure adopts a one-piece molded U-shaped elastic band, with a simple and reasonable overall structure that eliminates the need for complex adjustment mechanisms or additional power sources. Its elastic snap-fit ​​design makes installation and disassembly simple and intuitive; operators can fix or release the device with a simple pressing motion. This design not only reduces manufacturing and maintenance costs but also improves the equipment's applicability and reliability in different environments. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1 to 2 This utility model provides a technical solution: An installation auxiliary structure for an air compressor, characterized in that it comprises: Mounting base plate 1, wherein a pair of parallel limiting grooves 2 are provided on the lower surface of the mounting base plate 1; The auxiliary installation mechanism is an integrally formed U-shaped elastic band 31. The middle part of the U-shaped elastic band 31 is located below the mounting base plate 1, and the two sides extend upward in opposite directions. Near the mounting base plate 1, it is bent inward to form a pair of opposing L-shaped bending segments. The bent part of each L-shaped bending segment is inserted into the corresponding limiting groove 2, and the L-shaped bending segment and the limiting groove 2 are engaged with each other.

[0032] Specifically, a transition bracket 4 is fixedly installed in the middle of the lower surface of the mounting base plate 1. The transition bracket 4 is located between the pair of limiting grooves 2, which enables the concentrated transmission and stable support of the force below the mounting base plate 1. By fixing the transition bracket 4 in the middle position of the mounting base plate 1 and placing it between the pair of limiting grooves 2, the load transmitted from the air compressor to be installed can be preferentially borne by the transition bracket 4, reducing local deflection and off-center loading of the mounting base plate 1, thereby improving the overall rigidity and installation stability of the entire installation auxiliary structure.

[0033] Specifically, the arrangement of the adapter bracket 4, centered between the limiting grooves 2, creates a symmetrical support area centered on the adapter bracket 4 below the mounting base plate 1. A pair of limiting grooves 2 are located on either side of the adapter bracket 4, providing lateral and positional constraints for the L-shaped bend of the auxiliary installation mechanism. The adapter bracket 4 not only bears the downward pressure but also, together with the mounting base plate 1, defines the installation space for fasteners or vibration damping components, creating a coordinated structural relationship in terms of load-bearing, limiting, and connection.

[0034] In practical applications, this structural design, where the adapter bracket 4 is positioned in the middle of the mounting base plate 1 and located between a pair of limiting grooves 2, better adapts to the installation requirements of air compressors on vehicle chassis, fuel cell system racks, or other equipment bases. On the one hand, it facilitates the uniform transmission of vibrations and loads generated during air compressor operation to the downstream support structure; on the other hand, it allows for the configuration of vibration damping pads or connectors at the adapter bracket 4 according to different installation environments, thereby improving the versatility, adaptability, and long-term reliability of the installation auxiliary structure for air compressors.

[0035] Specifically, the adapter bracket 4 is fixedly connected to the lower surface of the mounting base plate 1, and a vibration damping pad is provided between the adapter bracket 4 and the mounting base plate 1. This effectively buffers and isolates the vibration generated during the operation of the air compressor while ensuring a reliable installation connection. By providing a vibration damping pad between the mounting base plate 1 and the adapter bracket 4, rigid contact between rigid components is avoided, reducing the direct transmission of vibration and impact to the mounting base plate 1 and the components above it. Furthermore, it reduces local stress concentration and improves the structural stability of the installation auxiliary structure under long-term loads and alternating operating conditions.

[0036] Specifically, this structure, where the vibration damping pad is positioned between the mounting base plate 1 and the adapter bracket 4, allows the vibrations generated by the air compressor during startup, shutdown, and high-frequency operation to be absorbed and attenuated first through the elastic deformation of the damping pad, before being transmitted to the downstream support structure by the adapter bracket 4. The damping pad provides elastic buffering in the thickness direction and a certain degree of displacement compensation in the planar direction, which helps reduce the risk of loosening at fastened connections, reduces noise and resonance caused by vibration, and thus improves the smoothness and reliability of the overall installation auxiliary structure.

[0037] In practical applications, this structural design, which incorporates vibration damping pads between the mounting base 1 and the adapter bracket 4, better adapts to the usage requirements of air compressors under various working conditions, such as vehicle chassis, engine compartment frames, or fixed frames. By rationally selecting the shape and parameters of the vibration damping pads, both load-bearing capacity and vibration reduction performance can be balanced in different installation environments. This ensures the installation strength of the air compressor while effectively reducing the impact of vibration on surrounding components and the overall structure, thereby improving the adaptability, durability, and service life of the air compressor's installation auxiliary structure.

[0038] Preferably, the L-shaped bending section includes a vertical section extending upward along the side of the U-shaped elastic band 31 and a horizontal section extending into the limiting groove 2 from the end of the vertical section along the extending direction of the limiting groove 2, which enables reliable limiting and stable connection of the auxiliary installation mechanism. By specifically defining the L-shaped bending section as a vertical section extending upward along the side of the U-shaped elastic band 31 and a horizontal section extending into the limiting groove 2 from the end of the vertical section along the extending direction of the limiting groove 2, the L-shaped bending section forms a clear bending profile in space, which not only ensures the insertion and engagement relationship with the limiting groove 2, but also facilitates control of the insertion depth and snap-fit ​​position, thereby improving the stability of the fit between the components in the installation auxiliary structure.

[0039] Specifically, this L-shaped bending structure, consisting of a vertical section and a horizontal section, arranges the vertical section along the side of the U-shaped elastic band 31 to determine the height position of the L-shaped bending section relative to the U-shaped elastic band 31. The horizontal section extends into the groove along the extension direction of the limiting groove 2, utilizing its length and cross-sectional shape to fit the inner wall of the limiting groove 2. The bends at the vertical and horizontal sections form clear corner boundaries, ensuring that the L-shaped bending section maintains its basic geometric shape under external forces, preventing twisting, overturning, and subsequent dislodging. This ensures a more reliable connection between the U-shaped elastic band 31 and the mounting base plate 1 during installation.

[0040] In practical applications, this L-shaped bending section structure with vertical and horizontal sections facilitates standardization and batch control during processing and assembly. By limiting the height of the vertical section and the extension length of the horizontal section, it can be matched with different specifications of mounting base plate 1 and limiting groove 2, ensuring that the L-shaped bending section can be smoothly inserted into the limiting groove 2 and that a stable snap-fit ​​state is formed after assembly. This improves the adaptability of the air compressor installation auxiliary structure in different installation scenarios and the consistency of repeated assembly.

[0041] Specifically, the middle section of the U-shaped elastic band 31 is an arc-shaped support section, with side sections on both sides connected to the arc-shaped support section and arranged opposite each other. The arc-shaped support section and the side sections together form an upward-opening U-shaped receiving space, which can achieve stable support and reliable limiting of the bottom of the air compressor body. By designing the middle section of the U-shaped elastic band 31 as an arc-shaped support section, and having the side sections on both sides together with the arc-shaped support section form an upward-opening U-shaped receiving space, the bottom of the air compressor can be accommodated in a more closely fitting support contour, increasing the support contact area, reducing local stress concentration, and thus improving the load-bearing stability and anti-displacement capability of the installation auxiliary structure for the air compressor.

[0042] Specifically, this U-shaped receiving space, composed of an arc-shaped support section and two side sections, features an arc-shaped support section that forms a curved or polygonal near-arc surface contact with the bottom of the air compressor. The two side sections are positioned opposite each other on either side of the air compressor body, providing lateral constraint on the air compressor through lateral positioning. The upward-facing arrangement allows the air compressor to be placed into the U-shaped receiving space from top to bottom during installation. The arc-shaped support section provides upward support, while the side sections provide lateral constraint. Together, these three elements form a supporting and encircling structure for the bottom of the air compressor, ensuring clearer positioning and greater stability of the air compressor within the installation auxiliary structure.

[0043] In practical applications, this U-shaped, upward-opening design facilitates compatibility with air compressor bottoms of varying sizes and shapes. By adjusting the curvature of the arc-shaped support section and the spacing of the side sections, it can accommodate various air compressor specifications and models, balancing installation convenience with support stability. Simultaneously, the U-shaped support structure helps maintain a relatively fixed installation posture during air compressor operation, reducing swaying and displacement caused by vibration or external forces, thereby improving the reliability and versatility of the air compressor installation auxiliary structure during long-term use.

[0044] Specifically, the U-shaped elastic band 31 is formed by bending a strip, the width direction of which is substantially perpendicular to the plane of the mounting base plate 1. This simplifies the forming method of the U-shaped elastic band 31 while ensuring the overall structural strength and elastic performance. By forming the U-shaped elastic band 31 by bending a strip, it maintains a continuous cross-sectional shape in the length direction and uniform cross-sectional dimensions in the thickness and width directions. This facilitates obtaining a regular U-shaped profile and consistent elastic characteristics, thereby improving the shape stability and repeatability of the installation auxiliary structure during repeated installation and disassembly processes.

[0045] Specifically, this strip-shaped component is bent into a U-shape, and its width direction is basically perpendicular to the plane of the mounting base plate 1. This arrangement allows the U-shaped elastic strip 31 to have a large cross-sectional dimension in the height direction, which is used to bear the load and provide support from top to bottom. At the same time, it maintains a small thickness dimension in the direction parallel to the plane of the mounting base plate 1, which facilitates the arrangement of L-shaped bending sections in a limited space and their fitting with the limiting groove 2. This orientation of the strip-shaped component's cross-sectional direction helps to control the bending stiffness and overall profile of the U-shaped elastic strip 31, reduce torsional deformation, and enable it to maintain a stable U-shaped support shape under stress.

[0046] In practical applications, this structural design, formed by bending a strip with its width direction substantially perpendicular to the plane of the mounting base plate 1, facilitates the standardized processing and mass production of the U-shaped elastic strip 31. By standardizing the width, thickness, and bending radius of the strip, it is easy to conduct serialized designs for mounting base plates 1 and air compressors of different specifications, taking into account load-bearing capacity, elastic characteristics, and structural compactness, thereby improving the adaptability and reliability of the air compressor installation auxiliary structure in different installation scenarios.

[0047] Specifically, when the U-shaped elastic band 31 is in a free state, the distance between the two L-shaped bending sections is greater than the distance between the two limiting grooves 2. When the U-shaped elastic band 31 is in the installed state, the distance between the two L-shaped bending sections matches the distance between the two limiting grooves 2. The bending part of each L-shaped bending section is respectively accommodated in the corresponding limiting groove 2, which can form a set of "free opening - installation compression" size matching relationship in the structure. This allows the installation auxiliary mechanism 3 to remain in an outward-opening state when not installed, and to achieve stable snap-fit ​​through the size matching between the two L-shaped bending sections and the limiting grooves 2 when installed, thereby achieving a good balance between assembly convenience and connection reliability.

[0048] Specifically, when the U-shaped elastic band 31 is in a free state, the distance between the two L-shaped bends is greater than the distance between the two limiting grooves 2, so that the U-shaped elastic band 31 will not interfere with the mounting base plate 1 and the limiting grooves 2 when it unfolds naturally; when the U-shaped elastic band 31 is pressed against the mounting base plate 1 and the two L-shaped bends are aligned with the limiting grooves 2, the distance between the two L-shaped bends is elastically contracted to match the distance between the two limiting grooves 2, and the bent part of each L-shaped bend extends into the corresponding limiting groove 2 and is constrained by the groove wall, forming a clear snap-fit ​​relationship geometrically.

[0049] In practical applications, this design of the difference in spacing between the free state and the installed state facilitates the rapid assembly and disassembly of the U-shaped elastic band 31 without the need for a complex locking mechanism. On the other hand, after installation, the snap-fit ​​mechanism formed by size matching makes it difficult for the L-shaped bending sections on both sides to come out of the limiting groove 2 under vibration or external force, thereby improving the vibration resistance and long-term reliability of the installation auxiliary structure for air compressors.
