Description

Technical Field

[0001] The invention relates to the technical field of urban rail vehicle air conditioning, and in particular to an air supply interface sealing structure for an urban rail vehicle air conditioning unit. Background Art

[0002] Urban rail transit refers to a vehicle transportation system that uses a track structure for load-bearing and guidance. In accordance with the requirements of the overall urban transportation plan, a fully or partially enclosed dedicated rail line is set up to transport a considerable amount of passenger flow in the form of trains or single vehicles. It is a public transportation mode, such as the city's subway or light rail system, trams, etc.; urban rail vehicles generally have an air duct system installed inside the ceiling, and the air conditioning units use the air duct system to achieve uniform air supply to the interior of the passenger compartment, providing a good riding environment for passengers on the subway vehicles.

[0003] Based on the above, the inventors have found that the existing sealing structure of the air supply interface of the urban rail vehicle air conditioner has the following main deficiencies. For example, the position where the existing air supply interface is connected to the interior of the car is prone to cracks due to long-term vibration of the train, causing the cold air of the air conditioner to escape, thereby affecting the cooling effect inside the car. In addition, the cold air of the air conditioner is directly blown into the interior of the car through the air duct, and the people located directly below the air conditioner are directly blown by the cold air, which can easily cause physical discomfort. Summary of the Invention

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Example 1: Please refer to Figure 1-Figure 5 , the specific embodiments of the present invention are as follows: Its structure includes a contact plate 1, an elastic rod 2, and an air supply structure 3. The top of the contact plate 1 is provided with an elastic rod 2, and there are four elastic rods 2. The elastic rods 2 on the left and right sides are fixedly connected to each other. The air supply structure 3 is fixedly connected to the top end face of the contact plate 1; the air supply structure 3 includes an air supply pipe 31, a fixing bolt 32, an air guide structure 33, and a filtering device 34. The air supply pipe 31 is located at the top end face of the contact plate 1. There are four fixing bolts 32, and the fixing bolts 32 fix the air supply pipe 31 to the contact plate 1. The end face of the plate 1, the air guide structure 33 is located at the inner bottom end of the air supply pipe 31, the filtering device 34 is set on the inner end face of the air supply pipe 31, the elastic rod 2 can be freely extended and retracted, and a spring with a reset function is provided inside the elastic rod 2, which is conducive to supporting the end face of the contact plate 1 through the elastic rod 2, so that the contact plate 1 can be attached to the top of the car under the elastic drive of the elastic rod 2, avoiding the cracks in the contact plate 1 caused by the vibration of the vehicle, allowing the cold air to flow directly into the car, and improving the cooling effect of the air conditioner on the interior of the car.

[0023] The filtering device 34 includes a support frame 341, a clamping structure 342, activated carbon 343, a partition 344, and filter cotton 345. The clamping structure 342 is provided on both sides of the support frame 341. The clamping structure 342 is clamped and fixed on the inner end face of the air supply pipe 31. The activated carbon 343 is arranged at the inner bottom end of the support frame 341. The partition 344 is located on the top of the activated carbon 343. The filter cotton 345 is arranged on the top end face of the partition 344. The bottom end face of the support frame 341 is hollow, which is conducive to the activated carbon 343 to absorb the odor contained in the cold air, so that the cold air blown into the car can maintain freshness, thereby improving the quality of the cold air in the car.

[0024] The clamping structure 342 includes a movable groove a1, a limit block a2, a guide block a3, a return spring a4, and a push rod a5. The movable groove a1 is arranged at the inner side end of the support frame 341, and the limit block a2 is clamped and installed on the end face of the movable groove a1. The guide block a3 is fixedly connected to the side end of the limit block a2. The return spring a4 is arranged on the left end face of the limit block a2. The push rod a5 is arranged at the bottom of the movable groove a1, and the push rod a5 is movably matched with the end face of the guide block a3. The angle formed between the end face of the guide block a3 and the push rod a5 is 45 degrees, which is conducive to the guide block a3 driving the limit block a2 to retract into the movable groove a1, so that the support frame 341 can be disassembled and repaired.

[0025] The top rod a5 includes an installation frame a51, a button a52, a rod body a53, and a tension spring a54. The installation frame a51 is set on the bottom end face of the movable groove a1, and the button a52 is clamped and installed inside the installation frame a51. The rod body a53 is vertically fixed on the top end face of the button a52. The tension spring a54 is set inside the installation frame a51. The tension spring a54 is movably cooperated with the end face of the button a52, which is conducive to pressing the button a52 to drive the rod body a53 to support the guide block a3 and move upward to disassemble the support frame 341, so that the maintenance personnel can use it again.

[0026] Based on the above embodiment, the specific working principle is as follows: the elastic rod 2 is used to support the end surface of the contact plate 1, so that the contact plate 1 can be attached to the top of the car under the elastic drive of the elastic rod 2, so as to prevent the contact plate 1 from being affected by the vibration of the vehicle and cracking, so that the cold air can flow directly into the car, thereby improving the cooling effect of the air conditioner on the interior of the car, and then the air conditioning cold air is filtered through the filter device 34, and the air flow is dispersed through the air guide structure 33, so that the air flow can flow evenly into the car, thereby preventing people in the car from being directly blown by the air conditioning cold air, and then the partition 344 is used to separate the end surface of the activated carbon 343 and the filter cotton 345, so that the activated carbon 343 and the filter cotton 345 can be disassembled for cleaning, and when the cold air flows from top to bottom, the air flow in the cold air can be filtered by the filter cotton 345, and then through the activated carbon 3 43 absorbs the odor contained in the cold air, so that the cold air blown into the car can maintain its freshness, thereby improving the quality of the cold air in the car, and then uses the support frame 341 to push upward into the inside of the air supply pipe 31, so that the limit block a2 can be stuck on the end face of the air supply pipe 31 under the drive of the return spring a4, thereby fixing the support frame 341. When the support frame 341 is to be disassembled for inspection and maintenance, the end face of the guide block a3 can be driven upward by pressing the push rod a5, so that the guide block a3 can drive the limit block a2 to shrink into the movable groove a1, thereby allowing the support frame 341 to be disassembled for inspection and maintenance, and finally, the push button a52 is used to drive the rod body a53 to push the guide block a3 upward to disassemble the support frame 341, and then the button a52 is reset by the tension spring a54 to move downward, so that the maintenance personnel can use it again.

[0027] Example 2: Please refer to Figure 6-Figure 7 , the specific embodiments of the present invention are as follows: The air guide structure 33 includes a frame 331, a fixing rod 332, an air guide plate 333, and a protective net 334. The side end of the frame 331 is provided with a fixing rod 332, and the fixing rod 332 is fixedly connected to the bottom end face of the contact plate 1. There are nine air guide plates 333, and the air guide plates 333 are arranged on the inner end face of the frame 331. The protective net 334 is fixedly connected to the bottom end face of the frame 331. The air guide plates 333 are inclined from the middle position of the frame 331 to the side end, and the inclination angle of the air guide plates 333 is 45 degrees, which is beneficial for the protective net 33 to prevent animals from entering the car through the ventilation duct.

[0028] The air guide plate 333 includes a plate body s1, a concentrated groove s2, and a ventilation groove s3. The two sides of the plate body s1 are fixedly connected to the frame body 331. There are more than five concentrated grooves s2, and the concentrated grooves s2 are arranged on the end face of the plate body s1. The ventilation groove s3 is located at the bottom end of the concentrated groove s2. The angle formed by the concentrated groove s2 and the end face of the plate body s1 is 60 degrees, which is conducive to allowing the entire compartment to have a better cooling effect without affecting the passengers.

[0029] Based on the above embodiment, the specific working principle is as follows: the frame 331 is used to support the air guide plate 333, so that the air guide plate 333 can guide the cold air to both ends, so that the cold air can flow evenly into the car, avoiding the cold air blowing directly on the people, and the protective net 334 can prevent animals from entering the car through the ventilation duct, and then use the plate s1 to guide the cold air, and then use the concentrating groove s2 to concentrate the airflow impacting the end face of the plate s1, so that the cold air can be diverted from the end face of the ventilation groove s3 to flow horizontally into the car, reducing the intensity of the cold air blowing vertically downward, and allowing all the cold air to flow into the car, without affecting the passengers, so that the entire car can have a better cooling effect.

[0030] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
