Description

Technical Field

[0001] The utility model relates to the technical field of parking air conditioners, and particularly relates to an earthquake-resistant and noise-reducing parking air conditioner for electric buses. Background Art

[0002] Commercial buses, especially trucks, often need to face various special working conditions during operation, such as waiting in the freight yard, loading and unloading goods, queuing for customs clearance, traffic jams, and parking at night. These links often result in the vehicle needing to park for a long time while the engine still needs to run at idle speed to maintain the temperature and comfort in the cab. The parking air conditioner uses the battery power of the truck to provide cooling or heating functions during the parking and rest stage, thus saving energy, reducing emissions, and reducing operating costs; since the parking air conditioner is usually installed additionally, its external unit is mostly fixed on the back or top side of the cab, and the space size is limited, resulting in relatively simple shock absorption measures, such as only using conventional rubber shock pads. However, this shock absorption method has poor effect under high-frequency vibration, especially at night or during the full-speed operation stage of the compressor, which seriously affects the rest quality of drivers and passengers. In addition, components such as compressors and fans inside the air conditioner unit will also generate vibration and noise during operation, further increasing the overall noise level. In order to solve the temperature control problem during the parking and rest stage, improve the rest quality of passengers, and reduce the discomfort caused by noise and vibration. An earthquake-resistant and noise-reducing parking air conditioner for electric buses is proposed, based on the comprehensive consideration of the special working condition requirements, vibration and noise problems, and safety and comfort requirements of commercial buses. Through continuous optimization of the design and adoption of advanced technologies, such products will improve the vehicle operation efficiency, reduce the operation cost, and improve the passenger experience.

[0009] In a preferred embodiment of the present utility model, a detachable cavity is arranged on the side of the air conditioner main body and the sound insulation board main body inside the frame structure.

[0010] The beneficial effects of the present utility model are as follows: After adopting the above structure, through the designed noise reduction box body assembly, the noise generated during the operation of the air conditioner is effectively isolated and reduced.

Specific embodiments

[0015] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0016] Such as Figure 1As shown in FIG. -2, an anti-seismic and noise-reducing electric bus parking air conditioner, which specifically includes an air conditioner main body, a frame structure 1, a noise-reducing box assembly, and an anti-seismic connection component. The above components form an air conditioner integral and are installed at the rear of the electric bus; a noise-reducing box assembly is arranged outside the frame structure 1. The noise-reducing box assembly includes a sound insulation board main body 2, a box body board 3, and a fixed connecting rod 4. The fixed connecting rod 4 is vertically installed on the frame structure 1. The box body board 3 is attached to the outside of the fixed connecting rod 4. A vertical sound insulation board main body 2 is connected inside the fixed connecting rod 4. Reinforcement devices extending out are arranged on the outer walls of the sound insulation board main body 2 near the upper and lower sides and are connected to the frame structure 1. A connecting frame 5 is arranged on the sound insulation board main body 2. The front outer wall of the connecting frame 5 is connected to the air conditioner main body. The anti-seismic connection components are arranged in an array at the four corners outside the box body board 3. In specific implementation, the air conditioner main body, as the core part of the air conditioning system, is responsible for refrigeration or heating, provides a comfortable temperature environment inside the vehicle, adapts to the power system and spatial layout of the electric bus, and ensures efficient and energy-saving operation; the frame structure 1, as the support frame of the entire air conditioning system, provides a stable installation foundation for other components. Its structure needs to consider anti-seismic performance to ensure stability during vehicle driving, and at the same time is convenient for installation and maintenance; the multi-layer structure of the sound insulation board main body 2 on the noise-reducing box assembly effectively isolates external noise and vibration, and at the same time prevents heat transfer, improving the comfort of passengers. The box body board 3 is attached to the outside of the fixed connecting rod 4 to form a closed space, and together with the sound insulation board main body 2, it forms a noise-reducing box, further enhancing the sound insulation effect. The fixed connecting rod 4, as the support structure of the sound insulation board main body 2 and the box body board 3, ensures that they are firmly installed on the frame structure 1. The anti-seismic connection components adopt a combination of connecting rods and spring shock absorbers to effectively absorb and reduce vibrations.

[0017] As Figure 1As shown, further based on the above method, the sound insulation board main body 2 includes a heat insulation board 6, a damping sound insulation board 7, a reinforcing rod 8 and a ventilation groove 9. The reinforcing rods 8 are arranged vertically and parallel to each other. The damping sound insulation boards 7 are arranged in sequence on the reinforcing rods 8. The heat insulation board 6 is attached to the outer side of the damping sound insulation board 7. The ventilation grooves 9 are arranged on both sides of the damping sound insulation board 7. In specific implementation, the heat insulation board 6 prevents the heat generated during the operation of the air conditioner from directly transferring to other parts of the sound insulation board main body 2 or the interior space of the vehicle. By isolating the heat, the heat insulation board can also protect internal materials such as the damping sound insulation board 7 from the influence of high temperature and extend their service life. The damping sound insulation board 7 is the core part of the sound insulation board main body 2, and its main function is to absorb and isolate noise. Through the damping characteristics of the material itself and the design of the multi-layer structure, the damping sound insulation board can effectively reduce the transmission and reflection of sound. The reinforcing rod 8 provides a stable support structure for the damping sound insulation board 7, not only enhancing the overall strength of the sound insulation board main body 2, preventing deformation or damage caused by vibration or external force, but also ensuring that the damping sound insulation board 7 can maintain the correct arrangement and position, so as to give full play to its sound insulation effect. The ventilation groove 9 promotes the air circulation inside the sound insulation board main body 2. This helps to prevent the temperature rise caused by heat accumulation and maintain the heat dissipation performance of the sound insulation board main body 2. At the same time, the ventilation groove can also reduce the material expansion or contraction caused by humidity change and maintain the stability and durability of the sound insulation board main body 2. In addition, the design of the ventilation groove can also reduce the sound reflection and resonance to a certain extent and further improve the sound insulation effect.

[0018] As Figure 3As shown, on the basis of the above method, further, the seismic connection component includes shock-absorbing feet 10, a first connecting rod 11, a second connecting rod 12, a spring shock absorber 13, and a rigid connecting plate 14. The shock-absorbing feet 10 are arranged on the box body plate 3. One end of the first connecting rod 11 and the second connecting rod 12 is hinged to the shock-absorbing feet 10, and the other end of the first connecting rod 11 and the second connecting rod 12 is hinged to the rigid connecting plate 14. The spring shock absorber 13 is connected between the first connecting rod 11 and the second connecting rod 12. The first connecting rod 11 and the second connecting rod 12 are parallel to each other. The spring shock absorber 13 is rotatably connected to the first connecting rod 11 and the second connecting rod 12. In a specific implementation, the shock-absorbing feet 10, as connection points, are firmly installed on the box body plate 3. It is the basis of the seismic connection component and bears the weight and vibration from the air-conditioning system. The first connecting rod 11 and the second connecting rod 12 allow the connecting rods to rotate and displace to a certain extent when subjected to vibration, thereby effectively transmitting and dispersing the vibration energy. The parallel arrangement not only enhances the structural stability but also ensures that the vibration energy can be evenly distributed on the two connecting rods, further improving the shock-absorbing effect. When the air-conditioning system is subjected to vibration, the spring shock absorber 13 can utilize its elastic characteristics to absorb and buffer the vibration energy, reducing the impact and damage of the vibration on the internal components of the air-conditioning system. The rotatable connection rotates and deforms to a certain extent while absorbing the vibration energy, thus more flexibly adapting to various vibration conditions. The rigid connecting plate 14, as the other connection point of the seismic connection component, is usually connected to other structures of the vehicle (such as the body frame). It is responsible for transmitting the remaining vibration energy after shock absorption treatment to the overall structure of the vehicle, thereby further dispersing and weakening the impact of vibration on the air-conditioning system.

[0019] As Figure 1 shown, on the basis of the above method, further, the reinforcement device includes alignment connection holes 15, reinforcement connecting rods 16, and limit rings 17. The limit rings 17 are arranged on the sound insulation board main body 2. The alignment connection holes 15 are arranged inside the limit rings 17. The reinforcement connecting rods 16 pass through the alignment connection holes 15 and the limit rings 17 to connect the sound insulation board main body 2 and the frame structure 1 to each other. In a specific implementation, the limit rings 17 are arranged on the sound insulation board main body 2 as the positioning and supporting points of the reinforcement connecting rods 16. Due to the existence of the limit rings 17, it can be ensured that the reinforcement connecting rods 16 can maintain the correct position and angle when passing through the alignment connection holes 15, thereby avoiding the deviation or loosening of the reinforcement connecting rods 16 during the installation process. The reinforcement connecting rods 16 pass through the alignment connection holes 15 and the limit rings 17, tightly connecting the sound insulation board main body 2 and the frame structure 1 together, enhancing the overall stability between the sound insulation board main body 2 and the frame structure, and also improving the load-bearing capacity of the entire structure. The firm connection and reinforcement between the sound insulation board main body 2 and the frame structure 1 ensure that the sound insulation board can maintain good sound insulation effect and service performance during long-term use.

[0020] As Figure 2As shown, on the basis of the above-mentioned method, a removable cavity 18 is further provided on the side of the air-conditioning main body and the sound insulation board main body 2 in the frame structure 1. In a specific implementation, the removable cavity 18 is provided on the side of the air-conditioning main body and the sound insulation board main body 2 in the frame structure 1, so as to facilitate the maintenance and overhaul of the air-conditioning system. The removable design enables maintenance personnel to easily enter the internal space, replace parts or perform cleaning work, thereby improving maintenance efficiency and convenience.

[0021] In the specific working process of the new type of anti-vibration and noise reduction electric bus parking air conditioner, start-up and cooling or heating: when the air conditioning system is started, the air conditioning body starts to work and performs cooling or heating according to the temperature requirements in the car. The air conditioning body uses the electricity provided by the electric bus to adjust the temperature in the car to a comfortable range through the internal circulation system and refrigerant or heating elements. Noise reduction process: The sound insulation board body 2 plays a key role in the noise reduction process. Its multi-layer structure heat protection board 6, damping sound insulation board 7 and ventilation groove 9 work together to effectively isolate external noise and vibration. The heat protection board 6 prevents the direct transfer of heat generated during the operation of the air conditioner, while protecting the internal sound insulation material from high temperature. The damping sound insulation board 7 absorbs and isolates noise, and reduces the propagation and reflection of sound through its damping characteristics and multi-layer structure. The ventilation groove 9 promotes air circulation and prevents heat accumulation, while reducing sound reflection and resonance, further improving the sound insulation effect. Anti-seismic process: The anti-seismic connection components absorb and reduce vibrations during the driving process of the vehicle. When the vehicle is vibrated, the shock-absorbing foot 10, as a connection point, bears the vibration and transmits it to the first connecting rod 11 and the second connecting rod 12. The first connecting rod 11 and the second connecting rod 12 rotate and displace to a certain extent, disperse the vibration energy, and absorb and buffer the vibration through the elastic characteristics of the spring shock absorber 13. The rotating connection of the spring shock absorber 13 allows it to flexibly adapt to various vibration conditions and reduce the impact of vibration on the internal components of the air conditioner. The rigid connecting plate 14 transmits the remaining vibration energy after the shock-absorbing treatment to the overall structure of the vehicle to further disperse and reduce the vibration. Structural stability and reinforcement: The fixed connecting rod 4 serves as the supporting structure of the sound insulation board body 2 and the box board 3 to ensure that they are firmly installed on the frame structure 1. The reinforcement device enhances the connection strength between the sound insulation board body 2 and the frame structure 1 to prevent deformation or damage caused by vibration or external force. The setting of the detachable cavity 18 facilitates the maintenance and repair of the air conditioning system to ensure the reliability and efficiency of long-term operation. In summary, the new anti-vibration and noise-reducing electric bus parking air conditioner realizes the functions of efficient cooling or heating, effective noise reduction and anti-vibration protection through the coordinated work of various components, providing electric bus passengers with a more comfortable and quiet riding environment.
