Description

Technical Field

[0001] The utility model belongs to the technical field of subway air conditioners, and particularly relates to an air conditioner vibration reduction and noise reduction device and a subway air conditioner. Background Art

[0002] Subway air conditioning units generate high- and low-frequency vibrations during operation. These vibrations are transmitted to the train compartments, creating noise and impacting passenger comfort. Typically, spring shock absorbers are installed at the bottom of the subway air conditioning units to absorb some of the vibration energy and reduce vibration transmission.

[0003] Conventional technology uses mounting slots on the upper surface of subway car shells for air conditioners. During installation, the air conditioner body is connected to the upper surface of the subway car, with the air outlet recessed within the slots. However, in the actual application of vibration damping for subway air conditioners, the spring shock absorbers installed on the upper surface of the subway car can only absorb vibrations generated by the air conditioner above the subway roof, and are less effective at absorbing vibrations generated by the air outlet within the mounting slots. Furthermore, the air outlet, disturbed by the airflow, vibrates and emits noise, further affecting the quietness of the train compartment. Utility Model Content

Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0026] Please also refer to Figures 1 to 6 The air conditioner vibration and noise reduction device provided by the present invention is now described. The air conditioner vibration and noise reduction device includes a mounting frame 10, a plurality of first buffer members 20, and a second buffer member 30. The mounting frame 10 is intended to be mounted within a mounting slot 81 on the top of a subway car 80. The mounting frame 10 is provided with a mounting hole 11 adapted to receive an air outlet 91 of a subway air conditioner 90. The first buffer members 20 are spaced apart on the inner circumferential wall of the mounting hole 11, and each first buffer member 20 abuts against the circumferential wall of the air outlet 91 of the subway air conditioner 90. The second buffer members 30 are spaced apart on the top surface of the mounting frame 10 surrounding the mounting hole 11, and are intended to abut against the lower mounting surface supporting the subway air conditioner 90.

[0027] It should be noted that the mounting bracket 10 can be arranged around the inner wall of the mounting groove 81, and the mounting bracket 10 has a flat surface extending outside the mounting groove 81, and the second buffer member 30 is arranged on this flat surface. The inner wall of the mounting hole 11 is aligned with the inner wall of the mounting groove 81 on the subway car 80, providing installation space for the subway air conditioner 90. The first buffer member 20 is arranged on the inner wall of the mounting hole 11. When the air outlet 91 of the subway air conditioner 90 is inserted into the mounting hole 11 for installation, it presses against the wall of the air outlet 91, providing vibration buffering for the wall of the air outlet 91. When the subway air conditioner 90 is installed, it can reduce the vibration collision between the air outlet 91 and the mounting groove 81, thereby reducing noise.

[0028] The beneficial effects of the air-conditioning shock absorption and noise reduction device provided by the present invention are as follows: compared with the prior art, the present invention adopts a mounting frame 10 provided with a mounting hole 11 to be installed on the top of the subway car 80, so that the first buffer member 20 and the second buffer member 30 are located between the subway air conditioner 90 and the subway car 80, and the second buffer member 30 on the mounting frame 10 is connected to the lower mounting surface of the subway air conditioner 90, so as to buffer and reduce shock of the subway air conditioner 90 when the subway is running, thereby reducing the vibration and noise generated by the subway air conditioner 90; the first buffer member 20 is provided on the inner wall of the mounting hole 11, and can abut against the peripheral wall of the air outlet 91 of the subway air conditioner 90, and can reduce the vibration impact between the peripheral wall of the air outlet 91 and the mounting groove 81 on the top of the subway car 80 when the subway air conditioner 90 is running, thereby reducing the vibration noise between the subway air conditioner 90 and the subway car 80 and improving the shock absorption ability.

[0029] In one possible implementation, see Figure 2 and Figure 3 A plurality of avoidance grooves 12 are arranged at intervals along the circumference of the hole wall of the mounting hole 11 , and a slide rail 13 is provided in each avoidance groove 12 . Each first buffer member 20 is respectively arranged in each avoidance groove 12 and slides with the slide rail 13 .

[0030] It should be noted that a plurality of avoidance grooves 12 are provided on the inner side wall of the mounting hole 11, and the first buffer member 20 is provided in the avoidance groove 12, which can buffer the vibrating wall of the air outlet 91 when the subway air conditioner 90 vibrates during operation. The avoidance groove 12 provides a buffering movement space for the first buffer member 20, so that the first buffer member 20 can offset the vibration generated by the wall of the air outlet 91 when the subway air conditioner 90 is running through its own buffering movement.

[0031] In one possible implementation, see Figure 4 and Figure 5 The first buffer member 20 includes a buffer plate 21, a first elastic member 22 and a sliding rod 23; the opposite sides of the buffer plate 21 are rotatably connected to the inner wall of the avoidance groove 12; one end of the first elastic member 22 is connected to the buffer plate 21, and the other end is connected to the sliding rod 23; the sliding rod 23 is slidably connected to the slide rail 13.

[0032] It should be noted that the first elastic member 22 can be a spring, one end of which is connected to the buffer plate 21 and the other end is connected to the slide bar 23, and can move in the vertical direction along the slide rail 13 following the slide bar 23. The opposite sides of the buffer plate 21 are rotatably connected to the inner wall of the avoidance groove 12, and the buffer plate 21 can rotate around the rotation axis. When the subway air conditioner 90 is in operation, the air outlet 91 vibrates, and the surrounding wall of the air outlet 91 squeezes the buffer plate 21. The buffer plate 21 rotates and squeezes the first elastic member 22 to compress the first elastic member 22. The first elastic member 22 can provide a buffer for the surrounding wall of the air outlet 91 to prevent the surrounding wall of the air outlet 91 from touching the inner wall of the mounting hole 11 and emitting collision noise. The two ends of the slide bar 23 are respectively slidably connected to the two slide rails 13. The slide rails 13 can limit the movement direction of the slide bar 23, so that the slide bar 23 always moves along the setting direction of the slide rails 13, and can avoid the offset of the two sides of the slide bar 23. It can also avoid the slide bar 23 from rotating when sliding on the slide rails 13 and applying torque to the first elastic member 22, thereby affecting the shock absorption effect of the subway air conditioner 90.

[0033] For some examples, see Figure 5 Both ends of the slide bar 23 are rotatably provided with sliders, and the two sliders are respectively slidably connected to the slide rail 13. The sliders are rotatably connected to the ends of the slide bar 23. When the buffer plate 21 is squeezed and rotated by the peripheral wall of the air outlet 91, the sliders slidably connected to the slide rail 13 change the position of the slide bar 23 by sliding in the vertical direction, and the slide bar 23 rotatably connected to the slider changes the connection angle between the slide bar 23 and the first elastic member 22, so that the buffer plate 21 offsets the rotation angle of the first elastic member 22 during rotation, so that the first elastic member 22 is always subjected to an extrusion force parallel to the setting direction of the first elastic member 22, thereby preventing the first elastic member 22 from being damaged due to the angle between the compression direction of the first elastic member 22 and the force direction.

[0034] In one possible implementation, see Figure 1 and Figure 2 , a first buffer layer 40 is provided on the buffer plate 21 .

[0035] It should be noted that when the subway air conditioner 90 is in operation, the walls surrounding the air outlet 91 vibrate and strike the buffer plate 21. The buffer plate 21 can offset the vibrations generated by the walls surrounding the air outlet 91 through the cushioning of the first elastic member 22. To prevent noise generated by the walls surrounding the air outlet 91 colliding with the buffer plate 21, a first buffer layer 40 is provided on the buffer plate 21. The first buffer layer 40 may be a rubber layer. Rubber is an elastic material that effectively absorbs energy and buffers vibrations. Rubber has excellent shock-absorbing and wear-resistant properties. It can absorb the impact energy when the walls surrounding the air outlet 91 strike the buffer plate 21 and cooperate with the first elastic member 22 to buffer the vibrations of the air outlet 91, thereby achieving the purpose of shock absorption and noise reduction.

[0036] In one possible implementation, see Figure 1 and Figure 2 , the second buffer member 30 is a sealing rubber ring.

[0037] It should be noted that the second buffer member 30 is mounted on the mounting bracket 10 and connected to the lower mounting surface of the subway air conditioner 90, located between the lower mounting surface of the subway air conditioner 90 and the upper surface of the subway car 80. The second buffer member 30 may be a sealing rubber ring. It cushions the vibrations generated by the subway air conditioner 90 during operation, dampening the vibrations and reducing the vibration noise between the lower mounting surface of the subway air conditioner 90 and the mounting bracket 10. Furthermore, the second buffer member 30 seals the gap between the mounting bracket 10 and the subway air conditioner 90, preventing rainwater from entering the subway car 80 through the top.

[0038] In one possible implementation, see Figure 3 and Figure 4 A second buffer layer 50 is sandwiched between the bottom surface of the mounting frame 10 and the top surface of the subway car 80 .

[0039] It should be noted that the second buffer layer 50 can be a rubber layer, which is provided on the bottom wall of the mounting frame 10. When the mounting frame 10 is installed on the subway car 80, the mounting frame 10 and the subway car 80 are both in contact with the second buffer layer 50. The second buffer layer 50 can provide a buffer for the mounting frame 10 when the subway air conditioner 90 is running, thereby avoiding vibration and noise between the mounting frame 10 and the subway car 80, and can improve the shock absorption and noise reduction effect of the device.

[0040] In one possible implementation, see Figure 3 and Figure 4 A third buffer layer 60 is sandwiched between the outer peripheral wall of the mounting hole 11 and the inner peripheral wall of the mounting groove 81 .

[0041] It should be noted that the third buffer layer 60 surrounds the mounting hole 11, is provided on the outer peripheral wall of the mounting hole 11, and is connected to the inner peripheral wall of the mounting groove 81 when the mounting frame 10 is installed on the upper surface of the subway car 80. The third buffer layer 60 between the inner peripheral wall of the mounting groove 81 and the outer peripheral wall of the mounting hole 11 can cushion the mounting frame 10 in the mounting groove 81, preventing the mounting frame 10 from vibrating and colliding with the inner peripheral wall of the mounting groove 81 to generate noise, thereby improving the shock absorption and noise reduction effect of the device.

[0042] In one possible implementation, see Figure 2 The bottom of the mounting hole 11 is detachably connected to a sound-absorbing louver 70 , which is used to shield the air outlet 91 of the subway air conditioner 90 .

[0043] It should be noted that the bottom of the mounting hole 11 is detachably connected to a sound-absorbing louver 70, which is located at the bottom of the air outlet 91 of the subway air conditioner 90. It can absorb the noise generated by the air outlet 91 of the subway air conditioner 90 when it is disturbed by the flowing airflow, and can improve the quietness inside the subway car 80.

[0044] In one possible implementation, see Figure 2 A locking member 14 is provided on the bottom of the mounting hole 11 , and a locking hole 71 is provided on the side wall of the sound-absorbing shutter 70 , and the locking member 14 is plugged into and matched with the locking hole 71 .

[0045] It should be noted that a locking hole 71 is provided on the side wall of the silencer louver 70. When the silencer louver 70 is aligned with the mounting hole 11 from below the bottom of the mounting hole 11, the locking piece 14 is aligned with the locking hole 71 to achieve a fixed connection between the silencer louver 70 and the bottom of the mounting hole 11.

[0046] See also Figure 6 The embodiment of the present invention further provides a subway air conditioner 90, which includes an air conditioner vibration reduction and noise reduction device and an air conditioner body, wherein the air conditioner vibration reduction and noise reduction device is arranged at the bottom of the air conditioner body.

[0047] It should be noted that during the installation of the subway air conditioner 90, the air conditioner vibration and noise reduction device can be first installed on the subway air conditioner 90 at the installation site, so that the air conditioner vibration and noise reduction device is fixed to the lower installation surface of the subway air conditioner 90. The air conditioner vibration and noise reduction device can serve as the lower shell of the subway air conditioner 90, and together with the air conditioner body, it forms a modular subway air conditioner 90. After assembly, the modular subway air conditioner 90 can be lifted to the upper surface of the subway car 80 using lifting equipment to achieve a fixed connection between the subway air conditioner 90 and the subway car 80.

[0048] The subway air conditioner 90 provided by the present invention has the following beneficial effects: Compared with the prior art, the subway air conditioner 90 of the present application is composed of an air conditioner body and an air conditioner vibration and noise reduction device. The air conditioner noise reduction device can serve as the lower shell of the air conditioner body and is installed on the upper surface of the subway car 80. It can reduce the vibration and impact generated by the subway air conditioner 90 and the upper surface of the subway car 80 during operation. It can also reduce the vibration and impact between the air outlet 91 of the subway air conditioner 90 and the mounting groove 81 on the top of the subway car 80 during operation. The subway air conditioner 90 equipped with the air conditioner vibration and noise reduction device can improve the vibration absorption capacity, reduce the noise generated by the subway air conditioner 90 during operation, and improve passenger comfort.
