Description
TECHNICAL FIELD
[0001] The present application relates to the air conditioning technical field, especially to a damping installation structure and a vehicle-mounted air conditioner. BACKGROUND
[0002] The compressor of the vehicle-mounted air conditioner is generally installed on the top of the vehicle. When the air conditioner is working, the compressor will vibrate and thus generate noise. Since the generated noise is located above the heads of the passengers in the vehicle, the noise will directly affect the comfort of the passengers in the vehicle.
[0003] In order to weaken the vibration of the compressor transmitted to the air conditioner unit, in the existing system, a first damper is generally arranged between the compressor and the compressor tray, and a second damper is arranged between the compressor tray and the unit installation base. The second damper is made of rubber and is fixed between the compressor tray and the unit installation base by bolts and nuts. Since the rubber pad is directly in contact with the compressor tray and the unit installation base, the rubber pad will always rub against the compressor tray and the unit installation base when the compressor is working, which causes the wear of the rubber pad and thus shortens the service life of the rubber pad, i.e., the second damper in the existing technology has the problem of short service life.
[0004] In the implementation of the present application, the inventors have found that at least the following problems exist in the prior art:
[0005] In the existing system, the second damper is a hollow rubber pad made of rubber, which is fixed between the compressor tray and the unit installation base by bolts and nuts. Since the rubber pad is directly in contact with the compressor tray and the unit installation base, the rubber pad will always rub against the compressor tray and the unit installation base when the compressor is working, which causes the wear of the rubber pad and thus shortens the service life of the rubber pad, i.e., the second damper in the existing technology has the problem of short service life.

[0054] In the embodiment, the number of the secondary dampers 2 is 4, which are respectively arranged at the four corners close to the tray 4. The secondary dampers 2 of the embodiment have two installation modes, which are positive installation and reverse installation. The so-called positive installation means that the first metal piece 21 is fixedly connected with the tray 4 (the flange part 212 is fixedly connected with the tray 4), and the second metal piece 22 is fixedly connected with the base 5 (the abutting part 222 is fixedly connected with the base 5); the so-called reverse installation means that the first metal piece 21 is fixedly connected with the base 5 (the flange part 212 is fixedly connected with the base 5), and the second metal piece 22 is fixedly connected with the tray 4 (the abutting part 222 is fixedly connected with the tray 4), both of which can play the effect of damping and vibration isolation, and the installation mode is flexible, which can meet more installation requirements.

The arrangement of the folded edge parts can enhance the strength of the base 5 and the tray 4, and facilitate the realization of the bearing and fixing functions.
[0056] Figure 4 、 Figure 5 and Figure 8 , the cross-sectional view of the secondary damper 2 is not distinguished from the first metal piece 21, the second metal piece 22 and the elastic piece 23, which are drawn as a whole.

There are at least two first boss brackets 52, and each first boss bracket 52 has at least one second boss bracket 53, and each second boss bracket 53 has at least one secondary vibration damper 2. For example, in this embodiment, there are four secondary vibration dampers 2 and two first boss brackets 52, which are arranged parallel to each other along the first direction of the base 5. The two ends of each first boss bracket 52 are fixedly connected to the first folded edge 51. One second boss bracket 53 can be provided on each first boss bracket 52, and two secondary vibration dampers 2 can be provided on each second boss bracket 53; or, two second boss brackets 53 can be spaced apart on each first boss bracket, i.e., the number of second boss brackets 53 matches the number of secondary vibration dampers 2, and each second boss bracket 53 corresponds to the position of one secondary vibration damper 2. The abutment portion 222 abuts against the surface of the second boss bracket 53 on the side away from the first boss bracket 52. The abutment portion 222 is fixedly connected to the second boss bracket 53 via the second connector 6. In this embodiment, the cross-sections of both the first boss bracket 52 and the second boss bracket 53 are U-shaped. The two ends of the first boss bracket 52 are fixedly connected to the first folded edge portion 51 of the base 5, which can enhance the strength of the base 5. The second boss bracket 53 is used to raise the position of the secondary vibration damper 2 to prevent the tray 4 from colliding with the first connector 7 and the base 5 during vibration. In this embodiment, the first direction can refer to the width direction of the base 5.

The two ends of the third boss bracket 54 are fixedly connected to the first folded edge part 51, and each third boss bracket 54 corresponds to at least one secondary vibration damper 2. That is, each third boss bracket 54 has at least one secondary vibration damper 2. The abutment part 222 abuts against the surface of the tray 4 near the third boss bracket 54, and the flange 212 is fixedly connected to the third boss bracket 54 through the first connector 7. The height of the third boss bracket 54 is higher than that of the first boss bracket 52 to accommodate the secondary vibration damper 2. The shape of the third boss bracket 54 is similar to that of the first boss bracket 52, with a "U"-shaped cross-section. Its two ends are fixedly connected to the first folded edge part 51 of the base 5, which can enhance the strength of the base 5. In this embodiment, the first direction can refer to the width direction of the base 5.

The first vibration isolating pad 333, the second vibration isolating pad 332, the connecting part 32 and the flat pad 331 are fixed on the mounting part 31 by fastening bolts and fastening nuts.
[0061] In this embodiment, there are three primary vibration dampers 3. In other embodiments, the number of primary vibration dampers may be more than three, and the specific number is not limited. In this embodiment, the primary vibration dampers 3 are located at both ends of the compressor 1, with two primary vibration dampers 3 at one end of the compressor 1 and one primary vibration damper 3 at the other end. The structure of the mounting part 31 in this embodiment is similar to that of the first boss bracket 52. During installation, the end of the mounting part 31 near the second folded edge 41 of the tray 4 can be fixedly connected to the second folded edge 41, thereby enhancing the strength of the tray 4 and the stability of the mounting part 31.
[0062] The compressor 1 of the embodiment is fixedly connected with the tray 4 through the connecting part 32, the first damper 3 and the mounting part 31, the connecting part 32 is arranged between the first vibration isolation pad 333 and the second vibration isolation pad 332, the first vibration isolation pad 333 and the second vibration isolation pad 332 can be made of rubber or other materials, and the first damper 3 can isolate and reduce the vibration of the compressor 1 through the first vibration isolation pad 333 and the second vibration isolation pad 332, so as to weaken the vibration of the compressor 1 transmitted to the tray 4.

After two times of damping, the vibration and noise of the compressor are greatly weakened, the damping and isolation rate is effectively improved, resonance between the damping device and the compressor during damping is avoided, the NVH (Noise, Vibration and Harshness) performance of the vehicle is improved, the passengers in the vehicle feel more comfortable, and the service life of the compressor is long. The second damper of the embodiment has simple structure and strong universality, and is very convenient to produce and manufacture.
