Description

Technical Field

[0001] This utility model relates to the field of transportation technology, and in particular to a shock-absorbing structure and vehicle. Background Technology

[0002] As an important mode of public transportation, buses are receiving increasing attention for their comfort and safety. In bus air conditioning systems, carbon dioxide refrigerant, due to its natural working fluid, environmental friendliness, and high safety, is expected to be widely used in the future of new environmentally friendly refrigerant air conditioning systems. Matching carbon dioxide compressors will also see widespread application in the industry. However, because carbon dioxide air conditioning compressors are typically quite heavy, they generate significant mechanical vibrations during operation. This vibration can not only affect the stability and lifespan of the air conditioning system but also potentially impact the overall smoothness of the vehicle's operation.

[0003] Traditional vibration damping solutions mainly employ structures such as rubber shock absorbers, which can mitigate vertical vibrations from the road surface or the equipment itself to a certain extent. However, in actual operation, the compressor of a bus generates horizontal mechanical vibrations during starting, braking, and turning. If these horizontal vibrations are not effectively controlled, they will not only affect the stability of the compressor but also easily resonate with the vehicle chassis, impacting passenger comfort.

[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0026] The first aspect of this utility model provides a shock-absorbing structure, such as... Figure 1 and Figure 2 As shown, it includes a base 1, a support assembly 2, a first damping assembly 3, and a second damping assembly 4. The support assembly 2 is located above the base 1. The first damping assembly 3 is installed between the base 1 and the support assembly 2. The first damping assembly 3 is inclined relative to the vertical direction and configured to dampen vibrations in both the vertical and horizontal directions. At least a portion of the structure of the second damping assembly 4 is located within the support assembly 2. The second damping assembly 4 is arranged in the vertical direction and configured to dampen vibrations in the vertical direction.

[0027] It is understandable that the above-mentioned support component 2 being located above the base 1 means that during use, the support component 2 is located above the base 1 in the vertical direction.

[0028] In use, the base 1 can be mounted on the sheet metal parts of the air conditioner, and the compressor 7 can be mounted on the support assembly 2. When the compressor 7 vibrates, the first damping assembly 3, being tilted relative to the vertical direction, can dampen vibrations both vertically and horizontally. Furthermore, the second damping assembly 4 can also work in conjunction with the first damping assembly 3 to dampen vibrations vertically.

[0029] The shock absorption structure mentioned in the above embodiments helps to ensure the stability of the compressor 7, reduce the resonance between the compressor 7 and the vehicle chassis, reduce the resonance between the compressor and the vehicle body frame and chassis, and make the passenger ride more comfortable.

[0030] The support component 2 can have various optional structures. Since the support component 2 is equipped with a second shock-absorbing component 4, the support component 2 can include two parts, and the two parts are damped by the second shock-absorbing component 4. Each part can adopt a plate structure or a block structure, etc.

[0031] In an optional embodiment, the support assembly 2 includes a first support frame 21 and a second support frame 22, the first support frame 21 being located between the base 1 and the second support frame 22, the first shock absorber 3 being installed between the base 1 and the first support frame 21, and the second shock absorber 4 being at least partially installed between the first support frame 21 and the second support frame 22.

[0032] The first damping component 3 is installed between the base 1 and the first support frame 21 to absorb vibration energy from the air conditioning product and the vehicle, thereby achieving the first-level damping effect. The second damping component 4 is at least partially installed between the first support frame 21 and the second support frame 22 to achieve at least the second-level damping effect, further improving the damping performance of the damping structure.

[0033] The first support frame 21 and the second support frame 22 can be made of metal materials (such as steel, aluminum alloy, etc.) or high-strength composite materials to ensure their structural strength and durability.

[0034] Specifically, such as Figure 3 As shown, the first support frame 21 has a plate-like structure and a groove 23 for avoiding the compressor 7. The groove 23 has a length direction parallel to the axial direction of the compressor 7 and a width direction perpendicular to the length direction. The second support frame 22 includes a first support beam 221 and a second support beam 222. The first support beam 221 and the second support beam 222 are respectively connected to both sides of the first support frame 21 along the width direction. The first support beam 221 and the second support beam 222 are spaced apart and used to install the compressor 7.

[0035] In the above embodiment, after the compressor 7 is installed on the first support beam 221 and the second support beam 222, the bottom of the compressor 7 can pass through the gap between the first support beam 221 and the second support beam 222 and enter the groove 23. This arrangement effectively reduces the installation height of the compressor 7. After the compressor 7 is installed, when projected horizontally onto the side of the compressor 7, a portion of the shock-absorbing structure can overlap with a portion of the compressor 7, resulting in a more compact installation structure.

[0036] In alternative implementations, such as Figure 3 As shown, the first damping assembly 3 includes a first damping member 31, the base 1 has a first inclined plate 11 with an angle between the first inclined plate 11 and the horizontal direction, the first support frame 21 has a second inclined plate 211 parallel to the first inclined plate 11, the first damping member 31 is installed between the first inclined plate 11 and the second inclined plate 211, and the extension direction of the first damping member 31 is perpendicular to the first inclined plate 11 and the second inclined plate 211.

[0037] Through the above structural design, the first damping component 3 can effectively absorb vibration energy from different directions, and can still maintain a good damping effect, especially under vibration input in non-vertical or non-horizontal directions. In addition, the normal mounting method of the two inclined plates and the first damping component 31 makes the structural layout more compact and suitable for equipment installation environments with limited space.

[0038] In the above embodiment, the first inclined plate 11 is arranged at an angle, forming a first angle α with the vertical direction and a second angle β with the horizontal direction, where both α and β are non-zero angles, and α + β = 90°. This inclined arrangement not only helps to adapt to the spatial layout of the overall structure and facilitates the installation of the first damping component 31, but also optimizes the direction of damping force.

[0039] In a preferred embodiment, both the first included angle α and the second included angle β are 45°.

[0040] The number of first damping components 31 can be one or more. Multiple first damping components 31 can be evenly distributed between the first inclined plate 11 and the second inclined plate 211 along the length direction of the first inclined plate 11 to enhance the stability and load-bearing capacity of the overall damping system.

[0041] like Figure 3 As shown, there are two of each of the first inclined plate 11 and the second inclined plate 211. The two first inclined plates 11 are located on both sides of the bottom of the compressor 7, and the two second inclined plates 211 are also located on both sides of the bottom of the compressor 7.

[0042] The first shock absorber 31 mentioned above can be a rubber shock absorber, a spring, a hydraulic shock absorber, or other components with buffering and energy absorption functions. Its specific type is not limited, as long as it can achieve the shock absorption function.

[0043] In an optional embodiment, the shock-absorbing structure further includes a first connecting component 5, which passes through the first inclined plate 11, the first shock absorber 31, and the second inclined plate 211 in a direction perpendicular to the first inclined plate 11, and defines the distance between the first inclined plate 11 and the second inclined plate 211 in a direction perpendicular to the first inclined plate 11.

[0044] By setting the first connecting component 5, not only can the structural connection between the first inclined plate 11 and the second inclined plate 211 be realized, but the relative distance between the two can also be limited to ensure the overall stability and consistency of the shock absorption structure.

[0045] The first connecting assembly 5 includes a bolt, a nut, and a washer, but is not limited to this form. Specifically, the bolt can pass through the first inclined plate 11, the first shock absorber 31, and the second inclined plate 211 and be locked by a nut, and the washer is located between the nut and the first inclined plate 11 or the second inclined plate 211.

[0046] In alternative implementations, such as Figure 3 As shown, the first support frame 21 also includes a first horizontal plate 212, and the first horizontal plate 212 is connected to the side of each of the two second inclined plates 211 facing away from the groove 23. Specifically, the second inclined plate 211 and the first horizontal plate 212 are integral structures, the first horizontal plate 212 is rectangular, and its length direction is arranged along the extension direction of the groove 23. The second support frame 22 includes two second horizontal plates 223, which are arranged parallel to and spaced apart from the two first horizontal plates 212 in a one-to-one correspondence.

[0047] Specifically, when the second support frame 22 includes a first support beam 221 and a second support beam 222, the first support beam 221 includes one of the second horizontal plates 223, and the second support beam 222 includes the other second horizontal plate 223.

[0048] The second damping assembly 4 includes a second damping element 41, which is installed between the first horizontal plate 212 and the second horizontal plate 223. It is used to absorb and buffer vibrations transmitted from the first support frame 21 to the second support frame 22 during the operation of the air conditioning product and the vehicle, thereby reducing direct impact between structures and improving the overall stability and service life of the compressor 7.

[0049] In alternative implementations, such as Figure 3As shown, the second damping assembly 4 also includes a third damping element 42, which is mounted on the side of the second support frame 22 opposite to the first support frame 21. The third damping element 42 is used to attenuate the vibration transmitted to the compressor 7 via the second support frame 22.

[0050] In a preferred embodiment, the second damping component 4 includes a second damping element 41 and a third damping element 42. The second damping element 41 and the third damping element 42, together with the first damping element 31, can achieve a three-level damping effect and improve the overall performance of the damping system.

[0051] The second damping component 41 and the third damping component 42 may be made of elastic materials, such as, but not limited to, rubber, polyurethane or composite elastomers, and their specific structural forms may be block-shaped, cylindrical, annular or other geometric shapes suitable for assembly and damping.

[0052] In alternative implementations, such as Figure 3 As shown, the second damper 41 and the third damper 42 are arranged opposite each other in the vertical direction to work together to absorb and buffer vibrations generated by the air conditioning product and the vehicle in the vertical direction.

[0053] In addition, such as Figure 3 As shown, the extension directions of the second damping member 41 and the third damping member 42 are both parallel to the vertical direction, which enables the second damping member 41 and the third damping member 42 to fully absorb vibration energy in the vertical direction and improve the response performance of the damping structure in the above direction.

[0054] Multiple second damping components 4 can be configured, with multiple second damping components 4 distributed on both sides of the compressor 7. For example... Figure 4 As shown, there are four second shock absorber components 4. Two of the four second shock absorber components 4 are distributed on one side of the compressor 7, and the other two are distributed on the other side of the compressor 7.

[0055] In an optional embodiment, the damping structure further includes a second connecting component 6, which passes through the first support frame 21, the second damping member 41, the second support frame 22 and the third damping member 42, and defines the distance between the first support frame 21 and the third damping member 42.

[0056] By setting the second connecting component 6, not only can the connection between the first support frame 21, the second damping component 41, the second support frame 22 and the third damping component 42 be realized, but the relative distance between the first support frame 21 and the third damping component 42 can also be limited, so as to ensure the overall stability and consistency of the damping structure.

[0057] The optional structure of the second connecting component 6 is the same as that of the first connecting component 5, for example, including bolts, nuts and washers.

[0058] In an optional embodiment, the groove 23 has a length direction parallel to the axial direction of the compressor 7 and a width direction perpendicular to the length direction, and the second damping component 4 is located outside the first damping component 3 along the width direction.

[0059] In the above embodiments, since the second damping component 4 is located outside the first damping component 3 along the width direction, and both the second damping component 4 and the first damping component 3 are connected to the first support frame 21, the installation position of the first damping component 3 will not interfere with the installation position of the second damping component 4. The installation of the first damping component 3 and the second damping component 4 is more flexible, and the structure of the damping structure is more compact.

[0060] In an optional implementation, the hardness of the second damping component 4 is less than the hardness of the first damping component 3.

[0061] Due to its high rigidity, the first damping component 3 provides strong support and cushioning when subjected to large impacts or vibrations. It primarily absorbs the initial impact force from air conditioning units and the vehicle, and effectively absorbs vibrations in both the horizontal and vertical directions. This high-rigidity design allows the first damping component 3 to respond quickly and absorb most of the impact energy.

[0062] The main function of the second damping component 4 is to further absorb the residual vibration after the initial damping by the first damping component 3. Due to its lower hardness, the second damping component 4 can more effectively absorb and attenuate small, high-frequency vibrations, thereby achieving a more refined and stable damping effect.

[0063] Specifically, the Shore hardness of the first damping component 31 is 60±5HA, and the Shore hardness of the second damping component 41 and the third damping component 42 is 50±5HA.

[0064] A second aspect of the present invention provides a vehicle, which includes a compressor 7 and the aforementioned shock-absorbing structure, wherein the compressor 7 is mounted on a support component 2 of the shock-absorbing structure.

[0065] The aforementioned vehicles may be, but are not limited to, buses.

[0066] Among them, compressor 7 can be a carbon dioxide air conditioning compressor. The compressor generates significant vibration during operation. The vibration damping structure provided in the above embodiment can effectively suppress the transmission of vibration and effectively avoid resonance with the whole vehicle. Actual tests show that the above vibration damping structure can reduce the vibration transmission rate by 75% and reduce the compressor noise by 5 dB(A).

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
