[0044] In one embodiment of the present invention, the roof 100 is the roof of a bus.

[0045] like Figure 1 and Figure 2 As shown, the connection assembly 10 also includes: a plurality of connecting members 110, the plurality of connecting members 110 are arranged at intervals between the air conditioner 200 and the roof 100, each connecting member 110 is provided with a connecting hole 120, and the connecting holes 120 on the plurality of connecting members 110 are arranged one-to-one with the plurality of bottom plate mounting holes on the air conditioner 200; a plurality of threaded rods 130 and a plurality of nuts, the plurality of threaded rods 130 and the plurality of nuts are arranged one-to-one with each other, the plurality of threaded rods 130 are arranged one-to-one with the plurality of connecting members 110 and the plurality of bottom plate mounting holes, one end of each threaded rod 130 is fixedly connected to the roof 100, and the other end of each threaded rod 130 is threadedly connected to the corresponding nut after passing through the corresponding connecting hole 120 and the bottom plate mounting hole. In this way, the plurality of connecting holes 120 are arranged one-to-one with the plurality of bottom plate mounting holes on the air conditioner 200, ensuring the accurate positioning of the air conditioner 200 on the roof 100. The use of the plurality of threaded rods 130 not only provides a reliable fastening force, but also allows for fine adjustment during installation of the air conditioner 200 to ensure an optimal vibration reduction effect.

[0046] Specifically, the connection hole 120 and the bottom plate mounting hole are through holes.

[0047] Specifically, the connectors 110 of the present invention are arranged in a rectangular array, ensuring uniform distribution of the entire vibration reduction device on the roof 100, so that the air conditioner 200 can obtain stable support and uniform vibration reduction effect at all positions. Each connector 110 shares a part of the load, avoiding local overload of the roof 100 and improving the working stability of the entire vibration reduction device.

[0048] Specifically, a plurality of mounting plates are arranged at intervals on the vehicle roof 100 of the present invention, for mounting a plurality of threaded rods 130 in a one-to-one correspondence.

[0049] like Figure 5 As shown, the connecting member 110 also includes: a first pad group 111, the first pad group 111 is used to contact the roof 100; a second pad group 112, the second pad group 112 is arranged at one end of the first pad group 111 close to the air conditioner 200, so as to contact the air conditioner 200; an elastic member group 113, the elastic member group 113 is arranged between the first pad group 111 and the second pad group 112; the elastic member group 113 is arranged between the first pad group 111 and the second pad group 112, and can provide instant vibration buffering and restoring force. Specifically, the elastic member group 113 will deform when impacted by vibration energy, absorb vibration energy, and quickly return to its original state after the vibration stops, thereby effectively preventing the continuous transmission of vibration energy and protecting the stability of the vehicle body.

[0050] Preferably, the connection hole 120 is provided through the first pad group 111, the elastic member group 113 and the second pad group 112, ensuring a stable and precise connection between the threaded rod 130 and the connection member 110. This design not only provides reliability of the connection between the roof 100 and the air conditioner 200, but also allows the connection member 110 to have a certain degree of freedom during the vibration process, thereby better adapting to changes in the vibration frequency.

[0051] Furthermore, the elastic member group 113 also includes a first elastic member 1131 and a plurality of second elastic members 1132, wherein the first elastic member 1131 is sleeved on the threaded rod 130, and the plurality of second elastic members 1132 are arranged at intervals around the first elastic member 1131. The first elastic member 1131 is sleeved on the threaded rod 130, and can provide elastic buffering along the axial direction of the threaded rod 130 to absorb longitudinal vibration energy. The plurality of second elastic members 1132 are arranged at intervals around the first elastic member 1131, which not only increases the absorption capacity of longitudinal vibration and lateral vibration, but also improves the overall vibration reduction effect through distributed elastic support.

[0052] like Figure 5As shown, the first cushion block group 111 also includes: a first connecting plate 1111, which is arranged above the roof 100; the arrangement of the first connecting plate 1111 increases the contact area between the first cushion block group 111 and the roof 100, thereby improving the structural strength and stability of the connection.

[0053] like Figure 6 As shown, the first pad group 111 also includes a connecting recess 1112, which is arranged on the connecting plate 1111 and is located on the side of the first connecting plate 1111 close to the elastic member group 113. The design of the connecting recess 1112 not only supports the elastic member, but also enhances the overall rigidity of the first pad group 111, reducing the structural fatigue and damage of the connecting member 110 that may be caused by long-term vibration. A first limiting hole 11121 and a plurality of second limiting holes 11122 are provided in the connecting recess 1112. The first limiting hole 11121 is provided correspondingly to the first elastic member 1131 to limit the lower end of the first elastic member 1131. The plurality of second limiting holes 11122 are provided correspondingly to the plurality of second elastic members 1132 to limit the lower ends of the plurality of second elastic members 1132 respectively. The first limiting hole 11121 is provided correspondingly to the first elastic member 1131, and the plurality of second limiting holes 11122 are provided correspondingly to the plurality of second elastic members 1132, which ensures the stability and accurate positioning of the elastic member during the vibration process, avoids displacement or deformation of the elastic member when subjected to large vibration, and ensures the continuity and reliability of the vibration reduction effect.

[0054] Specifically, the first limiting hole 11121 is coaxially arranged with the connecting hole 120 , and the aperture of the first limiting hole 11121 is larger than the aperture of the connecting hole 120 , thereby ensuring the limiting effect on the first elastic member 1131 .

[0055] like Figure 7 As shown, the first pad group 111 also includes an elastic pad 1113, and a mounting groove 1114 for mounting the elastic pad 1113 is provided on the connecting concave platform 1112, and the first limiting hole 11121 and the plurality of second limiting holes 11122 are all located at the bottom of the mounting groove 1114; wherein, the elastic pad 1113 is provided with a first clearance hole 11131 and a plurality of second clearance holes 11132, the first clearance hole 11131 is used to avoid the first elastic member 1131, and the plurality of second clearance holes 11132 are used to avoid the plurality of second elastic members 1132 in a one-to-one correspondence, and the addition of the elastic pad 1113 forms a multiple vibration reduction structure. It can work in conjunction with the first elastic member 1131 and the second elastic member 1132 to provide a more comprehensive vibration energy absorption layer. This multiple vibration reduction mechanism can significantly reduce the intensity of the vibration of the air conditioner 200 transmitted to the vehicle body.

[0056] Preferably, the elastic pad 1113 is made of sponge. The good elasticity and softness of the sponge material can effectively reduce deformation when it is impacted or vibrated. When vibration or impact force is applied to the sponge, the structure of the sponge will be compressed and deformed, absorbing part of the kinetic energy and converting it into internal energy, thereby reducing vibration transmission. At the same time, the molecular structure and internal pores of the sponge can produce a damping effect, reduce the vibration frequency and amplitude, and gradually dissipate the impact energy.

[0057] Specifically, the design of the mounting groove 1114 not only provides a mounting position for the elastic pad 1113, but also further accurately defines the positions of the first elastic member 1131 and the second elastic members 1132 by setting a first limiting hole 11121 and a plurality of second limiting holes 11122 at the bottom of the groove. The first clearance hole 11131 and the plurality of second clearance holes 11132 on the elastic pad 1113 ensure the unimpeded expansion and contraction of the first elastic member 1131 and the plurality of second elastic members 1132, and at the same time provide additional buffering around the first elastic member 1131 and the plurality of second elastic members 1132, protecting the first elastic member 1131 and the plurality of second elastic members 1132 from direct external impact, and reducing the potential damage of the first elastic member 1131 and the plurality of second elastic members 1132 under extreme conditions.

[0058] like Figure 5 As shown, the second cushion block group 112 also includes: two second connecting plates 1121; a plurality of telescopic steel frames 1122, the plurality of telescopic steel frames 1122 are sandwiched between the two second connecting plates 1121, and each telescopic steel frame 1122 includes two connecting bodies 11221 and a rotating shaft 11222, the two connecting bodies 11221 are cross-arranged, and the rotating shaft 11222 is rotatably passed through the intersection of the two connecting bodies 11221; wherein the upper ends of the two connecting bodies 11221 are connected to the first The two connecting bodies 11221 are connected to a second connecting plate 1121, and the upper ends of the two connecting bodies 11221 can move closer to or away from each other relative to the first second connecting plate 1121; the lower ends of the two connecting bodies 11221 are connected to another second connecting plate 1121, and the lower ends of the two connecting bodies 11221 can move closer to or away from each other relative to the second second connecting plate 1121; the distance between the two second connecting plates 1121 can be adjusted by rotating the two connecting bodies 11221 around the rotating shaft 11222.

[0059] Specifically, the design of the telescopic steel frame 1122 allows the distance between the two second connecting plates 1121 to be dynamically adjusted, so as to adjust the distance between the air conditioner 200 and the roof 100 .

[0060] Specifically, the first connecting plate 1111 and the second connecting plate 1121 can be made of metal or high-strength plastic. According to the installation requirements of the roof 100 and the air conditioner 200, the thickness of the first connecting plate 1111 and the second connecting plate 1121 can be set according to actual needs.

[0061] Specifically, the telescopic steel frame 1122 is welded between the two second connecting plates 1121. The design of the telescopic steel frame 1122 allows a certain displacement during vibration or impact, which can effectively reduce the transmission of vibration. Preferably, the telescopic steel frame 1122 is made of high-strength steel, which has good toughness and durability and can maintain the integrity of the structure when subjected to vibration. At the same time, the elasticity of the telescopic steel frame 1122 itself enables it to absorb vibration energy to a certain extent. Under the action of vibration, the deformation of the telescopic steel frame 1122 will convert part of the vibration energy into heat energy, dissipate the energy, and further reduce the impact of vibration on the structure. At the same time, the structure of the telescopic steel frame can offset vibrations of specific frequencies and enhance the vibration reduction effect.

[0062] like Figure 3 and Figure 4 As shown, the first vibration damping component 210 and the second vibration damping component 220 are arranged at intervals along the length direction of the roof 100, which can absorb the vibration generated by the evaporator 300 in a targeted manner, and provide support for a specific area of ​​the roof 100, reduce the transmission of vibration, and ensure that the vibration is absorbed more evenly. A plurality of return air ports 500 are arranged at a position close to the evaporator 300 of the roof 100, and a plurality of first intervals are formed between the plurality of return air ports 500. The first vibration damping component 210 includes a plurality of first vibration damping blocks 211, and the plurality of first vibration damping blocks 211 are arranged at the plurality of first intervals in a one-to-one correspondence. The present invention not only meets the ventilation requirements of the air conditioning system by arranging a plurality of return air ports 500 on the roof 100, but also forms a plurality of first intervals between the plurality of return air ports 500, providing space for the arrangement of the plurality of first vibration damping blocks 211, making the arrangement of the plurality of first vibration damping blocks 211 more reasonable, ensuring the vibration damping effect on the roof 100, and not affecting the normal ventilation between the air conditioner 200 and the interior of the vehicle body.

[0063] Preferably, the second vibration damping component 220 includes a plurality of second vibration damping blocks 221, and a plurality of bosses 600 are further provided at a position near the compressor 400 of the roof 100, a plurality of second intervals are formed between the plurality of bosses 600, and a plurality of second vibration damping blocks 221 are provided at the plurality of second intervals in a one-to-one correspondence. The provision of the plurality of second vibration damping components 220 can specifically absorb the low-frequency vibration force generated when the compressor 400 is running. Since the compressor 400 is one of the main vibration sources in the air conditioner 200, the second vibration damping blocks 221 are provided at the plurality of second intervals close to the compressor 400, so that the vibration is effectively isolated, and the influence of the vibration on the entire air conditioner 200 and even the interior of the vehicle body is reduced.

[0064] Specifically, the plurality of bosses 600 disposed on the roof 100 not only provide fixing points for the second vibration damping block 221 , but also enhance the structural stability of the roof below the compressor 400 , thereby reducing local deformation of the roof caused by the weight of the air conditioner 200 .

[0065] like Figure 8 and Fig. 9 As shown, the first vibration damping block 211 includes a first upper pad 2101 and a first lower pad 2102, and a plurality of first balls 2103 are arranged between the first upper pad 2101 and the first lower pad 2102; and / or the second vibration damping block 221 includes a second upper pad 2201 and a second lower pad 2202, and a plurality of second balls are arranged between the second upper pad 2201 and the second lower pad 2202. The plurality of first balls 2103 are arranged between the first upper pad 2101 and the first lower pad 2102, and the second balls are arranged between the second upper pad 2201 and the second lower pad 2202. In this way, the vibration damping and low friction characteristics of the balls are utilized, and since the balls can roll freely, the direct friction between the contact surfaces of the two pads is reduced, thereby effectively absorbing and dispersing the vibration energy and reducing the transmission efficiency of the vibration.

[0066] Preferably, the first vibration damping component 210 and the second vibration damping component 220 are made of high-elastic rubber material, and the first upper pad 2101 and the first lower pad 2102, the second upper pad 2201 and the second lower pad 2202, and the first lower pad 2102, the second lower pad 2202 and the roof 100 of the bus are all bonded with structural adhesive, which can effectively absorb the vertical and horizontal vibrations generated during the driving of the bus.

[0067] Specifically, the arrangement of the first ball 2103 and the second ball can reduce the horizontal displacement and friction between the air conditioner 200 and the roof 100. Since the vehicle is subjected to forces from different directions during driving, the ball can provide a certain degree of freedom in the horizontal direction, reduce the displacement and friction of the air conditioner 200 caused by lateral vibration, and ensure the stability of the air conditioner 200.

[0068] The present invention also provides a vehicle, including the above-mentioned vibration reduction device, the vehicle also includes a body and an air conditioner 200, the air conditioner 200 is installed on the roof 100 of the body, and the vibration reduction device is installed between the air conditioner 200 and the roof 100.

[0069] Preferably, the present invention can effectively absorb and disperse vibrations of different frequencies through the combined design of the first vibration damping component 210, the second vibration damping component 220, the first pad group 111, the second pad group 112, and the elastic member group 113, avoiding the limitations of a single vibration damping structure, and can effectively reduce the vibration transmission between the air conditioner 200 and the roof 100, reduce equipment wear and failure caused by vibration, and also reduce noise during equipment operation, providing passengers with a quieter and more comfortable riding experience.

[0070] In addition, the vibration reduction device of the present invention can also effectively absorb and buffer vibrations from the road surface in both vertical and horizontal directions.

[0071] The beneficial effects of the present invention are as follows:

[0072] 1. By designing a vibration reduction device between the air conditioner 200 and the roof 100 of the bus, the noise generated by the air conditioner 200 during operation received by the vehicle body is significantly reduced, thereby improving the comfort level of the environment inside the vehicle body.

[0073] 2. The vibration reduction device of the present invention reduces the mechanical wear of the air conditioner 200 caused by the vibration of the vehicle body, thereby extending the service life of the air conditioner 200 and reducing the frequency of maintenance and replacement of the air conditioner 200.

[0074] 3. The vibration reduction device of the present invention has a simple structure and is easy to install. It does not require complicated modifications to the bus roof 100 or the air conditioner 200 and is applicable to various types of buses.
