Description

Technical Field

[0001] The invention belongs to the technical field of pneumatic door pipeline protection equipment, and in particular relates to a door pump air pipe protection structure for a public bus. Background Art

[0002] With the rapid development of public transportation, buses, as an important means of transportation for urban travel, have received extensive attention for their safety and reliability. In the door control system of buses, the door pump air pipe is a key component for controlling the opening and closing of the doors. Its stability and durability are directly related to the normal operation of the bus and the safety of passengers.

[0003] First, during operation, buses are subject to various vibrations and impacts from the road surface, which will not only cause direct damage to the door pump air pipe, but may also affect its normal working performance; and the sealing of the door pump air pipe is the basis for its normal operation. If the door pump air pipe is invaded by external substances, it may cause problems such as insufficient gas pressure and pollution, which will affect its working performance; finally, the material and performance of the door pump air pipe are affected by the ambient temperature. Too high or too low temperature may damage the door pump air pipe and shorten its service life. High temperature may soften and expand the material, resulting in a decrease in the sealing of the air pipe; while low temperature may harden and shrink the material, increasing the brittleness of the air pipe. At the same time, temperature changes will also affect the volume and pressure of the gas. At high temperatures, the volume of the gas expands, which may cause the internal pressure of the air pipe to increase, increasing the risk of air pipe rupture; at low temperatures, the volume of the gas shrinks, which may cause the internal pressure of the air pipe to decrease, affecting the working efficiency of the air pump, and long-term operation in an environment with changing temperature will accelerate the aging process of the air pipe material and shorten its service life;

[0004] For example, the existing patent: Chinese patent application CN201921642094.7 provides a bus door pump air pipe protection structure. Although it can protect the pipeline, the impact of temperature on the pipeline is ignored. In an overheated or overcooled environment, or an environment with a large temperature difference between day and night, the pipeline will still affect its service life. Summary of the invention

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0047] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0048] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0049] Please see attached Figure 1-Figure 17 As shown, this embodiment provides a bus door pump air pipe protection structure, including a door 10, and a pneumatic component 20 is connected to the top of the door 10;

[0050] The pneumatic assembly 20 includes an air pump 21 fixedly connected to the top of the vehicle door 10, the outlet of the air pump 21 is connected to an air pipe 22, the top of the air pipe 22 is connected to a pneumatic telescopic rod 23, and the pneumatic telescopic rod 23 is rotatably connected to the top of the vehicle door 10;

[0051] The protection component 30 includes a wrapping component 31 fixedly connected to the outer ring of the trachea 22, and the inner cavity of the wrapping component 31 is fixedly connected to the shock absorbing component 32;

[0052] Thermostatic component 40, the thermostatic component 40 comprises a pipeline component 41 fixedly connected to the inner cavity of the wrapping component 31, and a regulating component 42 is fixedly connected below the wrapping component 31;

[0053] The temperature control component 50 includes a power supply component 51 fixedly connected to the upper part of the wrapping component 31, and the inner cavity of the power supply component 51 is movably sleeved with a lifting and lowering component 52;

[0054] When the ambient temperature changes, the material in the power-on component 51 changes in temperature, driving the lifting component 52 to rise and fall, adjusting the power-on component 51 to supply power to different temperature-adjusting parts in the regulating component 42, and the regulating component 42 adjusts the temperature of the inner cavity of the wrapping component 31 by heating or cooling the material in the pipeline component 41;

[0055] The shock absorbing assembly 32 is used to provide shock absorption to the air pipe 22 at multiple angles.

[0056] It should be noted that the shock absorbing assembly 32 surrounds the outer ring of the wrapping assembly 31 , and four are provided in a group, with multiple groups evenly arranged in the inner cavity of the wrapping assembly 31 , in order to protect all positions of the trachea 22 .

[0057] In this embodiment, under normal conditions, the wrapping component 31 wraps around the outer ring of the air pipe 22 to seal and protect it to prevent external dust and impurities from damaging the air pipe 22. When the vehicle vibrates during driving, the shock absorbing component 32 performs multi-angle shock absorption on the air pipe 22 in the inner cavity of the wrapping component 31, effectively absorbing and dispersing the vibration energy, and reducing the wear and damage of the air pipe 22 caused by vibration. When the ambient temperature changes, the material in the power-on component 51 is deformed due to the temperature change, driving the landing component 52 to rise and fall. The movement of the landing component 52 will change the connection state between the power-on component 51 and the regulating component 42, so that the landing component 52 will supply power to the heating or cooling part in the regulating component 42 according to different temperatures. When the ambient temperature rises, the regulating component 42 will cool the pipeline component 41 after being powered by the cooling part to prevent high temperature from damaging the air pipe 22; when the ambient temperature drops, the heating part of the regulating component 42 will be powered to heat the pipeline component 41 to prevent low temperature from causing hardening or cracking of the material in the air pipe 22.

[0058] Next, please refer to Figure 3-Figure 8 , Fig.14 The wrapping assembly 31 includes a main body tube 311 fixedly connected to the top of the vehicle door 10, a folding tube 312 is provided on the left side of the main body tube 311, and the inner cavities of the main body tube 311 and the folding tube 312 are both provided with sealing tubes 313, and the inner cavity of the sealing tube 313 is fixedly connected with a buffer layer 314;

[0059] The shock absorbing assembly 32 includes a mounting pad 321 fixedly connected to the outer ring of the sealing tube 313, an elastic rope 322 fixedly connected to the top of the mounting pad 321, a fixed block 323 fixedly connected to the top of the elastic rope 322, a sliding column 324 fixedly connected to the middle of the top surface of the mounting pad 321, the sliding column 324 movably sleeved in the inner cavity of the fixed block 323, a first spring 325 fixedly connected to the top of the sliding column 324, and the top of the first spring 325 fixedly connected to the top of the inner cavity of the fixed block 323;

[0060] The folding tube 312 is a foldable and retractable hose, which is arranged in the middle part of the left side of the main tube 311, and the main tube 311 is fixedly connected to the upper area of ​​the vehicle door 10. The foldable and retractable folding tube 312 can avoid affecting the practicality of the pneumatic telescopic rod 23.

[0061] It should be noted that a gap is left between the sliding column 324 and the inner wall of the fixed block 323 in order to cope with vibration forces in different directions.

[0062] In this embodiment, under normal conditions, the sealing tube 313 will be wrapped around the outer ring of the trachea 22 for protection, and the main tube 311 will also be protected around the outer ring of the trachea 22. When the vehicle vibrates during operation, the vibration force will first be transmitted to the sealing tube 313. At this time, the elastic rope 322 and the first spring 325 in the mounting pad 321 will jointly absorb and disperse the vibration. The elastic rope 322 can be extended and retracted at multiple angles along the top surface of the mounting pad 321, so as to cope with vibration forces from different directions. The first spring 325 can buffer the vibration by extending and retracting. The combination of the two can more effectively absorb and disperse the vibration energy, and the sliding column 324 can limit the extension and retraction direction of the elastic rope 322 and the first spring 325 to prevent them from being offset and ensure the shock absorption effect. When the pneumatic telescopic rod 23 is used, the trachea 22 is extended and retracted, and the folding tube 312 can be folded and contracted accordingly to adapt to the extension and retraction changes of the trachea 22, thereby not affecting the normal use of the trachea 22.

[0063] Next, please refer to Figure 9-14 The pipeline assembly 41 includes a receiving groove 411 opened in the inner cavity of the sealing tube 313, and a temperature conducting tube 412 is spirally arranged in the inner cavity of the receiving groove 411. The inlet and outlet of the temperature conducting tube 412 both extend out of the sealing tube 313 and the main tube 311. A water tank 413 is fixedly connected to the lower part of the main tube 311, and the outlet of the temperature conducting tube 412 extends into the water tank 413;

[0064] The regulating component 42 includes a liquid pump 421, and the bottom surfaces of the main tube 311 are fixedly connected with a heating box 422 and a refrigeration box 423 respectively. The inner cavities of the heating box 422 and the refrigeration box 423 are both coiled with a copper tube 424, and the left and right ends of the copper tube 424 are respectively connected to the water tank 413 and the inlet of the liquid pump 421, the inner cavity of the heating box 422 is fixedly connected with an electric heating tube 425, the inner cavity of the refrigeration box 423 is fixedly connected with a refrigeration tube 426, and the outer circle of the refrigeration tube 426 is fixedly connected with a heat dissipation end 427, and the heat dissipation end 427 extends out of the refrigeration box 423.

[0065] It should be noted that the interior of the cooling tube 426 is a semiconductor cooling plate, the heat dissipation end 427 is a device for assisting the operation of the cooling plate, and the electric heating tube 425 is equipped with an electric heating wire, so as to heat or cool the liquid according to demand.

[0066] In this embodiment, when it is necessary to perform constant temperature treatment around the air pipe 22, the liquid pump 421 is operated to drive the liquid in the inner cavity of the temperature conducting tube 412 to flow, and the flowing liquid will pass through the water tank 413 and the copper tube 424 into the heating box 422 and the refrigeration box 423. When it is necessary to cool down the area around the air pipe 22, the refrigeration tube 426 works to cool down the liquid in the copper tube 424, and the cooled liquid enters the temperature conducting tube 412, cools down the sealing tube 313 and the air pipe 22, and prevents the high temperature from damaging the air pipe 22. At the same time, the heat dissipation end 427 can dissipate the heat in the refrigeration box 423 to the outside, thereby improving the cooling effect. When it is necessary to heat up the area around the air pipe 22, the electric heating tube 425 works to heat the liquid in the copper tube 424, and the heated liquid enters the temperature conducting tube 412, heats up the sealing tube 313 and the air pipe 22, and prevents the low temperature from causing hardening or cracking of the material in the air pipe 22.

[0067] Next, please refer to Figure 15-17 The power supply component 51 includes a storage box 511 fixedly connected to the top of the main tube 311, the right side of the storage box 511 is electrically connected to a connection wire 512, the right side of the inner cavity of the storage box 511 is electrically connected to a conductive rod 513, the connection wire 512 is electrically connected to the conductive rod 513, the upper and lower sides of the left side of the inner cavity of the storage box 511 are respectively provided with an upper guide rod 514 and a lower guide rod 515, the upper guide rod 514 and the lower guide rod 515 are electrically connected to a power transmission wire 516, a filling groove 517 is opened at the bottom of the inner cavity of the storage box 511, an elastic sleeve 518 is fixedly connected to the top of the filling groove 517, and the filling groove 517 is filled with mercury in the area below the elastic sleeve 518;

[0068] The landing assembly 52 includes a power rod 521 slidably connected to the outer ring of the conductive rod 513, a push rod 522 is fixedly connected to the bottom of the power rod 521, a push plate 523 is fixedly connected to the bottom of the push rod 522, and the bottom surface of the push plate 523 is contacted and connected to the top surface of the elastic sleeve 518, a limit rod 524 is slidably connected to the left side of the power rod 521, and the upper and lower ends of the limit rod 524 are fixedly connected to the left side of the inner cavity of the storage box 511, the inner ring of the power rod 521 is electrically connected to the conductive ring 525, and the conductive ring 525 is contacted and connected to the outer ring of the conductive rod 513, and a second spring 526 is fixedly connected to the top of the inner cavity of the storage box 511, and the bottom of the second spring 526 is fixedly connected to the top surface of the power rod 521;

[0069] There are two power transmission lines 516 , which are electrically connected to the electric heating pipe 425 and the cooling pipe 426 respectively, and supply power to them.

[0070] It should be noted that the power rod 521 has a built-in power material, which is electrically connected to the conductive rings 525 at the left and right ends, respectively, so that the current on the conductive rod 513 can be transferred to the upper guide rod 514 or the lower guide rod 515 through the power rod 521, thereby supplying power to the electric heating tube 425 or the cooling tube 426.

[0071] In this embodiment, when the ambient temperature changes, the mercury in the filling slot 517 will change according to the ambient temperature. If the ambient temperature is high, the mercury will expand, thereby pushing the elastic sleeve 518 up, and the elastic sleeve 518 will push the push plate 523 and the push rod 522 up, so that the power rod 521 rises and contacts the upper guide rod 514. At this time, the current of the conductive rod 513 will be transmitted to the upper guide rod 514 through the conductive ring 525 and the power rod 521, and then through the power transmission line 512 connected to the upper guide rod 514. 6 supplies energy to the cooling tube 426 to cool down. If the ambient temperature is low, the mercury will shrink, and the elastic sleeve 518 will shrink together. At this time, the second spring 526 will rebound, pushing the push plate 523, the push rod 522 and the power rod 521 down, so that the power rod 521 contacts the lower guide rod 515. At this time, the current of the conductive rod 513 will be transmitted to the lower guide rod 515 through the conductive ring 525 and the power rod 521, and then the electric heating tube 425 will be supplied with energy through the power transmission line 516 connected to the lower guide rod 515 to increase the temperature. In this way, the opening and closing of the electric heating tube 425 and the cooling tube 426 are controlled by the volume change of mercury due to thermal expansion and contraction, so as to realize the automatic adjustment of the temperature around the air pipe 22 and ensure the stability and service life of the air pipe 22.

[0072] The working principle of the present invention is as follows: under normal conditions, the sealing tube 313 will be wrapped around the outer ring of the trachea 22 for protection, and the main tube 311 will also be protected around the outer ring of the trachea 22. When the vehicle generates vibration during operation, the vibration force will first be transmitted to the sealing tube 313. At this time, the elastic rope 322 and the first spring 325 in the mounting pad 321 will jointly absorb and disperse the vibration. The elastic rope 322 can be extended and retracted at multiple angles along the top surface of the mounting pad 321, so as to cope with vibration forces from different directions. The first spring 325 can buffer the vibration by extending and retracting. The combination of the two can more effectively absorb and disperse the vibration energy, and the sliding column 324 can limit the extension and retraction direction of the elastic rope 322 and the first spring 325. , to prevent it from deflecting and ensure the shock absorption effect; when the pneumatic telescopic rod 23 is used, the folding tube 312 can be folded and contracted accordingly when the air pipe 22 is extended and retracted, so as to adapt to the extension and retraction changes of the air pipe 22, so as not to affect the normal use of the air pipe 22. When it is necessary to ensure the constant temperature around the air pipe 22, the liquid pump 421 drives the liquid in the inner cavity of the temperature conducting tube 412 to flow, and the flowing liquid passes through the water tank 413 and the copper tube 424 into the heating box 422 and the refrigeration box 423. When the ambient temperature changes, the mercury in the filling tank 517 will change according to the ambient temperature. If the ambient temperature is high, the mercury will expand, thereby pushing the elastic sleeve 518 up, and the elastic sleeve 518 will push the push plate 523 and the push rod 522 up, so that The power rod 521 rises and contacts the upper guide rod 514. At this time, the current of the conductive rod 513 will be transmitted to the upper guide rod 514 through the conductive ring 525 and the power rod 521, and then the refrigeration tube 426 will be powered through the power transmission line 516 connected to the upper guide rod 514. At this time, the refrigeration tube 426 works to cool the liquid in the copper tube 424. The cooled liquid enters the temperature conducting tube 412 to cool the sealing tube 313 and the air pipe 22 to prevent the high temperature from damaging the air pipe 22. At the same time, the heat dissipation end 427 can dissipate the heat in the refrigeration box 423 to the outside to improve the cooling effect. If the ambient temperature is low, the mercury will shrink, and the elastic sleeve 518 will shrink together. At this time, the second spring 526 will rebound to push the push plate 523 and the push rod 522 and the power rod 521 descend, so that the power rod 521 contacts the lower guide rod 515. At this time, the current of the conductive rod 513 will be transmitted to the lower guide rod 515 through the conductive ring 525 and the power rod 521, and then the electric heating tube 425 will be powered by the power transmission line 516 connected to the lower guide rod 515. At this time, the electric heating tube 425 works to heat the liquid in the copper tube 424. The heated liquid enters the temperature conducting tube 412, and the sealing tube 313 and the air pipe 22 are heated to prevent the low temperature from causing the material in the air pipe 22 to harden or crack. The volume change of mercury due to thermal expansion and contraction is used to control the on and off of the electric heating tube 425 and the refrigeration tube 426, thereby realizing automatic adjustment of the temperature around the air pipe 22 and ensuring the stability and service life of the air pipe 22.
