Description

TECHNICAL FIELD

[0001] The utility model relates to air outlet air pressure collection detection technical field, concretely relates to a kind of air outlet air pressure collection device of automobile air conditioning performance. BACKGROUND

[0002] Automobile air conditioning system is an important component of automobile comfort configuration, and its performance directly affects the comfort experience of passengers in the car. And air outlet air pressure, as one of the key parameters to measure the performance of automobile air conditioning system, has an important influence on the air supply effect, refrigeration and heating efficiency of air conditioning system. Accurate measurement of air outlet air pressure helps to optimize the design of air conditioning system, improve energy utilization efficiency and improve the passenger's ride experience. For example, reasonable air pressure can ensure that the air in the car is evenly distributed, quickly reach the set temperature, and avoid the situation of local uneven heating and cooling.

[0003] The existing air outlet air pressure collection device made of acrylic transparent plate or stainless steel plate faces many challenges in the manufacturing process. Due to the different sizes of the air outlet of the automobile air conditioning box, it is difficult to accurately manufacture air pressure collection devices that fit different size air outlets without special instruments and equipment. This leads to low production efficiency of air pressure collection devices in actual application, and it is difficult to meet the diversified needs. For example, on the automobile production line, the air outlet sizes of air conditioners of different vehicle models are different. If the traditional manufacturing method is used, air pressure collection devices need to be designed and manufactured for each vehicle model, increasing production cost and time cost.

[0004] In the performance test of automobile air conditioning system, the heat preservation measure of traditional air pressure collection device is crucial to the accuracy of data collection. If the heat preservation measure is not in place, the collected air outlet temperature will deviate, which will affect the evaluation of air conditioning system performance indicators. For example, in cold environment, if the heat preservation effect of air pressure collection device is not good, the low temperature outside will make the collected air outlet temperature lower than the actual temperature, leading to misjudgment of air conditioning heating performance.

[0005] Therefore, there is an urgent need for an air pressure collection device that can adapt to various sizes of automobile air outlet, collect air pressure conveniently, and effectively reduce temperature difference interference. Using a new type of air pressure collection device can quickly and accurately obtain the air pressure data of automobile air outlet without increasing too much cost. UTILITY MODEL CONTENTS

[0044] Example 1:

[0045] like Figures 1-11 As shown, a device for collecting air pressure at the air outlet of an automotive air conditioner includes:

[0046] Air guide assembly 1 and air pressure acquisition device 2;

[0047] The air guide component 1 is installed at the air outlet of the air conditioning unit. Its function is to guide the airflow blown out by the air conditioning unit and create a stable environment for wind pressure collection.

[0048] The air guiding assembly 1 includes an insulation box 11 and a connecting plate 12. The connecting plate 12 is located on the side of the insulation box 11 near the air outlet of the air conditioning unit. It can effectively guide the airflow blown out of the air outlet of the air conditioning unit smoothly into the insulation box 11. The connecting plate 12 is detached and installed on the insulation box 11 through a quick-release assembly 3. This quick-release design greatly facilitates the installation, maintenance and repair of the equipment. When it is necessary to measure the air pressure of air outlets of different specifications or when the equipment needs to be repaired, the staff can use the quick-release assembly 3 to quickly separate the connecting plate 12 from the insulation box 11 for replacement without cumbersome tools and complicated disassembly procedures, which greatly improves work efficiency.

[0049] The wind pressure collecting device 2 is installed on the heat preservation box 11, one end of the wind pressure collecting device 2 is connected with the inner cavity of the heat preservation box 11, the other end of the wind pressure collecting device 2 is connected with the pressure transmitter, the wind pressure collecting device 2 collects the wind pressure in the inner cavity of the heat preservation box 11 and transmits it to the pressure transmitter, the wind pressure collecting device 2 is in sealed connection with the heat preservation box 11, which guarantees the air tightness of the connection and prevents wind pressure leakage from causing measurement errors.

[0050] It should be noted that the heat preservation box 11 is fixedly provided with a first sealing rubber strip 13, the first sealing rubber strip 13 is concave, the connecting plate 12 is provided with a second sealing rubber strip 123 corresponding to the first sealing rubber strip 13, the second sealing rubber strip 123 is convex, the first sealing rubber strip 13 and the second sealing rubber strip 123 are in abutting and sealing arrangement, the sealing rubber strip itself has good elasticity and flexibility, during the operation of the equipment, even if it is impacted by air flow and the thermal expansion and contraction of components caused by temperature changes, the first sealing rubber strip 13 and the second sealing rubber strip 123 can still maintain close fitting state by relying on their own characteristics, they effectively prevent air flow from leaking from the connection between the heat preservation box 11 and the connecting plate 12, avoid heat loss or the mixing of external cold air caused by air flow leakage, thereby maintaining the precise stability of the air flow temperature in the heat preservation box 11, and ensuring that the pressure transmitter can analyze and process based on real and reliable data.

[0051] The heat preservation box 11 is composed of an aluminum foil heat preservation plate 112, which can effectively reduce the influence of external environment temperature on the air flow temperature in the box, ensure the accuracy of wind pressure collection, also has good moisture-proof and waterproof performance, is suitable for humid environment, the aluminum foil layer can also resist corrosion of various chemicals, can prolong the service life, is light in weight but high in strength, is convenient for transportation and installation, at the same time has good pressure resistance and drop resistance, is simple to install, the aluminum foil heat preservation plate 112 can also be cut according to requirements, adapts to different shapes and sizes, so that the internal space is sufficient to accommodate stable air flow and will not cause air flow disorder due to too large space.

[0052] It should be noted that the quick release assembly 3 comprises a pressing strip 35 which is hingedly installed on the heat preservation box 11, and a plurality of groups of magnetic holes 351 are arranged on one side of the pressing strip 35 which is in abutment with the connecting plate 12, and a plurality of magnetic blocks 121 corresponding to the magnetic holes 351 are arranged on the connecting plate 12, and the magnetic blocks 121 are fixedly connected with the connecting plate 12, when it is needed to install the connecting plate 12, the worker only needs to move the connecting plate 12 close to the pressing strip 35, and the magnetic blocks 121 are aligned with the magnetic holes 351, under the action of the magnetic force, the magnetic blocks 121 will be quickly and accurately embedded in the magnetic holes 351, and the connection of the two is completed, when it is needed to replace the connecting plate 12, the worker only needs to overcome the magnetic force between the magnetic blocks 121 and the magnetic holes 351, and the connecting plate 12 can be easily removed, and the quick release design of the magnetic type not only improves the installation and disassembly efficiency, but also enhances the stability of the connection.

[0053] Further, the quick release assembly 3 further comprises a lock catch 31, a fixed seat 32, a pressing handle 33 and a clamping piece 34, the lock catch 31 is fixedly installed on the pressing strip 35, the fixed seat 32 is fixedly installed on the heat preservation box 11, the pressing handle 33 is hingedly arranged with the fixed seat 32, and the clamping piece 34 is hingedly arranged with the pressing handle 33, and the fixed seat 32 is connected with the lock catch 31 through the pressing handle 33 and the clamping piece 34.

[0054] Further, the lock catch 31 comprises an installation part 311 and a clamping part 312, the installation part 311 is connected with the pressing strip 35 through a bolt, the clamping part 312 is arranged in an arc shape, and the clamping part 312 is arranged in clamping with the clamping piece 34, when the two are matched, the arc-shaped structure can better fit the contour of the clamping piece 34, so as to improve the tightness and stability of the clamping.

[0055] It should be further explained that the pressing handle 33 is provided with a limiting piece 331, a sliding groove 332 is formed in the pressing handle 33, the limiting piece 331 is slidingly installed in the sliding groove 332, a limiting part 321 corresponding to the limiting piece 331 is arranged on the fixed seat 32, the limiting piece 331 is arranged in clamping with the limiting part 321, the tail end of the limiting piece 331 is arranged in a curved shape, and after the tail end of the limiting piece 331 is clamped with the limiting part 321, the situation that the connecting plate 12 and the heat preservation box 11 are connected loose or separated due to the lifting of the pressing handle 33 caused by external force can be prevented.

[0056] In addition, the clamping piece 34 comprises a connecting portion 341 and a connecting rod 342 symmetrically arranged on both sides of the fixing seat 32, one end of the connecting portion 341 is connected with the fixing seat 32, the other end of the connecting portion 341 is connected with the connecting rod 342, and both ends of the connecting rod 342 are arranged on the connecting portions 341 on both sides. When the operator presses down the handlebar 33, the rotation of the handlebar 33 drives the clamping piece 34 to displace. Due to the connection between the connecting portion 341 and the fixing seat 32, the clamping piece 34 can accurately move towards the lock catch 31 and finally realize the clamping with the lock catch 31. In the clamping state, the connecting rod 342 and the connecting portion 341 jointly bear the force from the lock catch 31 and uniformly disperse the force to the fixing seat 32, thereby ensuring the stability of the quick release assembly 3 as a whole.

[0057] The connecting portion 341 comprises a first connecting plate 3411, a second connecting plate 3412 and a spring 3413. The first connecting plate 3411 and the second connecting plate 3412 are arranged in opposition. One end of each of the first connecting plate 3411 and the second connecting plate 3412 is provided with a limiting block 3414 abutting against an end of the spring 3413. The spring 3413 is sleeved on the first connecting plate 3411 and the second connecting plate 3412. In a natural state, both ends of the spring 3413 are in close contact with the limiting blocks 3414, thereby providing a certain pre-tightening force for the first connecting plate 3411 and the second connecting plate 3412 and maintaining a relatively stable positional relationship therebetween.

[0058] In actual work, the positions of the first connecting plate 3411 and the second connecting plate 3412 can be adaptively adjusted according to the movement posture of the clamping piece 34 and the external force acting thereon. When the clamping piece 34 moves towards the lock catch 31, if a slight positional deviation or external force interference is encountered, the spring 3413 can adjust the positions of the first connecting plate 3411 and the second connecting plate 3412 through compression or stretching of itself, thereby ensuring that the connecting rod 342 can accurately and tightly clamp with the lock catch 31.

[0059] Further, the heat preservation box 11 is provided with an air pipe 111 at the top thereof, and a gas distribution opening 14 is formed in the top of the heat preservation box 11 corresponding to the air pipe 111. The air pipe 111 is arranged at the top center of the heat preservation box 11. In terms of air flow distribution and operation efficiency, vertical air outlet can guide the air flow to diffuse more uniformly in the heat preservation box 11. When the air outlet is horizontal, due to the influence of gravity and the box wall, the air flow is prone to form a dead zone at the bottom or corner, resulting in inaccurate wind pressure collection. Vertical air outlet can make the air flow fully mix with the air in the heat preservation box 11 during the rising process, reduce the local concentration and turbulence of the air flow, and make the air flow in the wind pressure collection area more stable and uniform, thereby improving the accuracy and reliability of the wind pressure collection data.

[0060] Compared with the horizontal air outlet in the prior art, the vertical air outlet layout greatly reduces the angle adjustment and pipeline arrangement difficulty during installation of the air pipe 111 at the top of the heat preservation box 11. Compared with the horizontal air outlet which needs complex pipeline switching and fixing on the side, the vertical air outlet only needs to vertically connect the air pipe 111 upwards. In terms of space utilization, the vertical air outlet structure is more compact, effectively avoiding the problem of occupying too much horizontal space in the limited space inside the vehicle by the horizontal air outlet pipeline.

[0061] Furthermore, the mounting hole 15 is arranged on the side wall of the heat preservation box 11, the air pressure collecting device 2 is connected with the inner cavity of the heat preservation box 11 through the mounting hole 15, and the mounting hole 15 is arranged at the center position of the aluminum foil heat preservation plate 112. In this way, the stability and integrity of the overall structure of the heat preservation box 11 can be maintained, the stress at the center position of the aluminum foil heat preservation plate 112 is relatively balanced, the weakening degree of the overall strength of the heat preservation box 11 is the lowest after the mounting hole 15 is arranged, and the original structure and performance of the heat preservation material of the aluminum foil heat preservation plate 112 are not damaged. The heat preservation box 11 can continuously and effectively isolate the interference of the external environment temperature on the internal airflow, and the stability of the air pressure collecting environment is ensured.

[0062] Secondly, the center area of the aluminum foil heat preservation plate 112 is at a position where the airflow is relatively stable and uniform. The mounting hole 15 arranged at this position can collect the most representative air pressure data, and the measurement deviation caused by local airflow fluctuation or unevenness is minimized, so as to accurately reflect the real air pressure of the air outlet of the air conditioner.

[0063] In addition, the connecting plate 12 is provided with an air inlet 122, the air inlet 122 is connected with the air outlet of the air conditioner box, and the air inlet 122 and the air outlet are connected in a size-matched and clamped manner. In terms of airflow transmission, the size-matched and clamped connection can ensure that the airflow from the air outlet of the air conditioner box smoothly and efficiently enters the air inlet 122, reduces the airflow resistance and energy loss caused by size mismatch, and ensures the stability of the air volume and air speed of the air guide system. In the maintenance and use scene, when the equipment needs to be cleaned, maintained or replaced, the disassembly process is relatively simple, the staff can easily separate the connecting plate 12 from the air outlet of the air conditioner box, improve the maintenance efficiency, and the stable connection can withstand the influence of factors such as vibration and temperature change generated by the equipment operation, and will not cause connection failure due to loosening, thereby ensuring the reliability and stability of the entire air guide system.

[0064] Further, the connecting plate 12 is provided with a limiting groove 124 on the side connected with the heat preservation box 11, and a protective sponge 125 is arranged in the limiting groove 124. The air outlet of the air conditioning box is connected with the connecting plate 12 through the limiting groove 124, and the air outlet of the air conditioning box is arranged in clamping mode with the limiting groove 124. The protective sponge 125 is filled in the limiting groove 124, so that the sealing performance of the connecting position is further enhanced. When the air outlet of the air conditioning box is clamped with the limiting groove 124, the protective sponge 125 is deformed by extrusion and fills the small gap between the air outlet of the air conditioning box and the limiting groove 124, so that air leakage is prevented, the air volume of the air conditioning system is stabilized, the air pressure collection is more accurate, and the influence of air leakage on the refrigeration or heating effect of the air conditioning is avoided.

[0065] The device generates vibration during operation. The protective sponge 125 is elastic and can buffer the vibration transmission between the air outlet of the air conditioning box and the connecting plate, reduce the component wear and noise caused by vibration, prolong the service life of the device, create a more stable working environment for the air pressure collection device, prevent vibration interference with the accuracy of air pressure measurement, and reduce maintenance and replacement costs.

[0066] It should be noted that the air pressure collection device 2 includes an air pressure collection joint 21 and a static pressure collection pipe 22. One end of the air pressure collection joint 21 is in sealed connection with the mounting hole 15, so that the air pressure environment in the inner cavity of the heat preservation box 11 is not disturbed by the outside world, and the air pressure data in this environment can be accurately obtained by the air pressure collection joint 21. The other end of the air pressure collection joint 21 is in sealed connection with the static pressure collection pipe 22, so that the air pressure data will not deviate due to leakage during transmission. The static pressure collection pipe 22 is connected with a pressure transmitter.

[0067] It should be further noted that the air pressure collection device 2 is provided with three groups, two of which are arranged on the two sides of the collection box. These two groups of devices can effectively capture the air pressure information carried by the airflow entering the collection box from the side, because in actual working conditions, the airflow does not always enter the collection box directly from the air outlet. There may be complex airflow disturbance on the side, for example, in some special air conditioning systems of some vehicles, the structure near the air outlet may cause part of the airflow to be deflected and enter the collection box from the side. At this time, the air pressure collection devices 2 on the two sides can timely sense the air pressure changes of the side airflow.

[0068] The other group of air pressure collection devices 2 is arranged on the side of the collection box opposite to the air outlet, which is the most direct position to obtain the air pressure data of the main airflow from the air outlet of the air conditioning box. This device can accurately measure the air pressure of the airflow impacting the collection box from the front, which plays a key role in comprehensively understanding the air pressure condition of the air outlet of the air conditioning box.

[0069] The wind pressure collecting devices 2 of the three groups are connected through the static pressure collecting pipes 22, so that the data collected by the wind pressure collecting devices 2 can be associated with each other, through comprehensive analysis of the wind pressure data at different positions, the system can more accurately judge the overall wind pressure distribution of the air outlet of the air conditioning box, effectively avoid the one-sidedness caused by collecting data at a single position, thereby greatly improving the accuracy of wind pressure collection and the stability of the system, and providing more reliable data support for subsequent evaluation of the performance of the automobile air conditioner.

[0070] The installation process: in the installation process, the connecting plate 12 is first connected with the pressing strip 35 through magnetic attraction, the connecting plate 12 is close to the heat preservation box 11, so that the first sealing rubber strip 13 and the second sealing rubber strip 123 are in contact, the operator holds the pressing handle 33 and lifts it upward, the clamping piece 34 will approach the lock buckle 31 with the rotation of the pressing handle 33, and then the pressing handle 33 is pressed down, the clamping piece 34 and the lock buckle 31 are clamped. After clamping, the quick release assembly 3 can tightly connect the heat preservation box 11 and the connecting plate 12 together, at the same time, due to the elastic action of the clamping piece 34, it can also compensate for the small error in the connection process, ensure the tightness and stability of the connection. When disassembly is needed, the operator only needs to lift the pressing handle 33 upward, the clamping piece 34 will be separated from the lock buckle 31, so as to realize the quick disassembly of the heat preservation box 11 and the connecting plate 12, the operation is very convenient.

[0071] The air guide assembly 1 is connected with the air outlet of the air conditioning box, the air enters the inside of the heat preservation box 11 through the air inlet 122, and then is discharged through the air pipe 111 at the top of the heat preservation box 11. When the air flows through the static pressure collecting pipe in the heat preservation box 11, the pressure in the pipe is equal to the static pressure of the air. After the air enters the pipe stably, the pressure is transmitted to the pressure transmitter connected with the pipe through the pipe body. The pressure transmitter converts the static pressure into an electric signal or other measurable signal form, which is then collected and analyzed.

[0072] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
