Description

Technical Field

[0001] This utility model relates to the field of duct pressure loss testing technology, and in particular to a support device. Background Technology

[0002] Air conditioning duct pressure loss refers to the pressure loss caused by frictional resistance, bends, valves, supply and return air outlets, and other local resistances when air flows in the duct of an air conditioning ventilation system. This pressure loss is an important factor that must be considered in the design and operation of the ventilation system, as it directly affects the system's air volume, energy consumption, and air delivery effect, ultimately affecting the air conditioning's cooling, heating, defrosting, and defogging performance.

[0003] Air conditioning duct pressure loss testing is an important part of the installation and commissioning process of ventilation and air conditioning systems. Its purpose is to ensure the installation quality of the duct system, verify whether the ducts and their components can meet the design requirements, and ensure the efficiency and economy of the system operation.

[0004] In the existing technology, when the pressure loss of the air conditioning duct is measured, the placement of the air conditioning duct will also affect the pressure loss measurement. Therefore, multiple support components are usually set on the top of the pressure loss box to support the multiple air outlet pipes of the air conditioning duct, so that the placement of the air conditioning duct is consistent with the position inside the actual vehicle. However, the position of the support components cannot be adjusted. Therefore, this setting is prone to causing the position of the air conditioning duct to be inaccurate, resulting in a large error in the test results.

[0005] Therefore, it is necessary to provide a new support device to solve the above-mentioned technical problems. Utility Model Content

Two first fixing rods are respectively disposed at one end of the first base rod and one end of the second base rod, and two second fixing rods are respectively disposed at the other end of the first base rod and the other end of the second base rod. The two ends of the second reinforcing members are respectively connected to the first base rod and the second base rod, and the plurality of second reinforcing members are spaced apart along the second direction.

[0016] In one embodiment, the base further includes two connectors and two widening rods. The connectors have a first connecting hole and a second connecting hole. The first bottom rod is installed in the first connecting hole of one of the connectors, and one of the widening rods is installed in the second connecting hole of one of the connectors.

[0018] In one embodiment, the base further includes a brake pad rotatably mounted on the mounting base, the brake pad being rotatable to abut against the caster wheel to prevent the caster wheel from rotating.

[0019] In the above scheme, the support device is used to support the air conditioning duct. The support device includes a base and a first support assembly. The first support assembly includes two first support components spaced apart on the base along a first direction. The first support component includes a first support rod, a second support rod, a third support rod, and a first fixed rod extending in a vertical direction. The first support rod, the second support rod, and the third support rod are slidably installed on the first fixed rod from top to bottom, and the first support rod, the second support rod, and the third support rod can all rotate around the first fixed rod.

The two outlets in the middle of the short duct are connected to the other two air outlets respectively. Then, the pressure loss box is placed at the bottom of the support device. During testing, the positions of the short duct, two long ducts, and four air outlets are arranged according to the position of the air conditioning duct in the actual vehicle. Then, the first support rod, second support rod, and third support rod on the two first support components are driven to slide along the length of their respective first fixed rods and rotate around their respective first fixed rods, so that the tops of the two first support rods on the two first support components abut against the bottoms of the two long ducts to support them. The tops of the two second support rods on the support components abut against the bottoms of the two air outlets connected to the long air ducts, respectively, to support the two air outlets connected to the long air ducts; the tops of the two third support rods on the two first support components abut against the bottoms of the two air outlets connected to the short air ducts, respectively, to support the two air outlets connected to the short air ducts. This sequentially supports six points of the air conditioning duct, ensuring that the position and angle of the air conditioning duct are consistent with the actual vehicle, thus ensuring the accuracy of the air conditioning duct pressure loss measurement. In this embodiment, by setting first, second, and third support rods that can be adjusted vertically and rotated around a vertical axis, multiple points of the air conditioning duct are supported, ensuring that the position and angle of the air conditioning duct are consistent with the actual vehicle during the air conditioning duct pressure loss measurement, thereby guaranteeing the accuracy of the test results. Furthermore, during testing, only the first, second, and third support rods need to be moved individually to complete the support work for the air conditioning duct, improving the work efficiency during testing.

[0030] When performing pressure loss testing on air conditioning ducts, the placement of the ducts can affect the measurement. Therefore, multiple supports are usually installed on the top of the pressure loss test chamber to support the multiple air outlets of the air conditioning ducts, ensuring that the placement of the air conditioning ducts is consistent with the position inside the vehicle. However, the position of the supports cannot be adjusted. This can lead to inaccurate positioning of the air conditioning ducts when testing different vehicles, resulting in significant errors in the test results.

[0031] Figure 1 In the diagram, X represents the first direction, Y represents the second direction, and Z represents the vertical direction.

[0032] Please see Figure 1 and Figure 2 , Figure 1In this invention, X represents the first direction, Y represents the second direction, and Z represents the vertical direction. The present invention proposes a support device 100 for supporting air conditioning ducts. The support device 100 includes a base 1 and a first support assembly 2. The first support assembly 2 includes two first support components 21 spaced apart along the first direction on the base 1. Each first support component 21 includes a first support rod 211, a second support rod 212, a third support rod 213, and a first fixed rod 214 extending along the vertical direction. The first support rods 211, 212, and 213 are slidably mounted on the first fixed rod 214 from top to bottom, and all three support rods are capable of rotating around the first fixed rod 214. Specifically, the air conditioning duct includes one short duct, two long ducts, and four air outlets. When measuring the pressure loss of the air conditioning duct, the airflow meter is connected to the input port of the pressure loss box, and the output port of the pressure loss box is connected to a flow stabilizing fixture. The short duct is installed on the flow stabilizing fixture and has four outlets. The outlets on both sides of the short duct are connected to the two long ducts respectively. The ends of the two long ducts furthest from the short duct are each connected to an air outlet. The two outlets in the middle of the short duct are connected to the other two air outlets respectively. Then, the pressure loss box is placed at the bottom of the support device 100. During testing, the positions of the short air duct, two long air ducts, and four air outlets were arranged according to the actual vehicle's air conditioning duct layout. Then, the first support rods 211, 212, and 213 on the two first support components 21 were driven to slide along the length of their respective first fixed rods 214 and rotate around their respective first fixed rods 214. This caused the tops of the two first support rods 211 on the two first support components 21 to abut against the bottoms of the two long air ducts, thus supporting the two long air ducts. The tops of the two second support rods 212 on component 21 abut against the bottoms of the two air outlets connected to the long air ducts, respectively, to support the two air outlets connected to the long air ducts; similarly, the tops of the two third support rods 213 on the two first support components 21 abut against the bottoms of the two air outlets connected to the short air ducts, respectively, to support the two air outlets connected to the short air ducts. This provides sequential support for six points of the air conditioning duct, ensuring that the position and angle of the air conditioning duct are consistent with the actual vehicle, thus ensuring the accuracy of the air conditioning duct pressure loss measurement; in this embodiment... By setting up a first support rod 211, a second support rod 212, and a third support rod 213 that can be adjusted vertically and rotated around a vertical axis, multiple points of the air conditioning duct are supported. This ensures that the position and angle of the air conditioning duct are consistent with the actual vehicle when measuring the pressure loss of the air conditioning duct, thereby guaranteeing the accuracy of the test results. At the same time, during the test, the support work of the air conditioning duct can be completed by simply moving the first support rod 211, the second support rod 212, and the third support rod 213, which improves the work efficiency during the test.

[0033] Please see Figure 1 and Figure 2 , Figure 1 In the first embodiment, X represents the first direction, Y represents the second direction, and Z represents the vertical direction. In one embodiment, the support device 100 further includes a second support component 3. The first support component 2 and the second support component 3 are spaced apart along the second direction. The first direction is perpendicular to the second direction. The second support component 3 includes two second support members 31 spaced apart along the first direction on the base 1. The second support member 31 includes a fourth support rod 311 and a second fixed rod 312 extending along the vertical direction. The fourth support rod 311 is slidably mounted on the second fixed rod 312, and the fourth support rod 311 can rotate around the second fixed rod 312. During testing, the positions of the short air duct, two long air ducts, and four air outlets were arranged according to the actual vehicle's air conditioning duct layout. Then, the first support rods 211, 212, and 213 on the two first support components 21 were driven to slide along the length of their respective first fixed rods 214 and rotate around their respective first fixed rods 214. This caused the tops of the two first support rods 211 on the two first support components 21 to abut against the bottoms of the two long air ducts, supporting them; and the tops of the two second support rods 212 on the two first support components 21 to abut against the bottoms of the two air outlets connected to the long air ducts, supporting them; and the tops of the two first support rods 211 on the two first support components 21 to abut against the bottoms of the two air outlets connected to the long air ducts, supporting them; and the tops of the two second support rods 212 on the two first support components 21 to abut against the bottoms of the two air outlets connected to the long air ducts; and the tops of the two first support rods 211 on the two first support components 21 to abut against the bottoms of the two air outlets connected to the long air ducts. The tops of the two third support rods 213 on the support component 21 respectively abut against the bottoms of the two air outlets connected to the short air ducts to support the two air outlets connected to the short air ducts; then, the two fourth support rods 311 of the two second support components 31 are driven to slide along the length direction of the two second fixed rods 312 to adjust the position of the two fourth support rods 311 in the vertical direction, and make the two fourth support rods 311 rotate around their respective second fixed rods 312 to adjust the angle of the two fourth support rods 311. At this time, the tops of the two fourth support rods 311 abut against the bottoms of the connection between the two long air ducts and the short air ducts respectively, supporting the connection between the long air ducts and the short air ducts, which can further improve the support stability.

[0034] Please see Figure 1 and Figure 2In one embodiment, the length of the first support rod 211 is less than the length of the second support rod 212, and the length of the second support rod 212 is less than the length of the third support rod 213. Since the first support rod 211, the second support rod 212, and the third support rod 213 support different points, the required lengths of the first support rod 211, the second support rod 212, and the third support rod 213 are not the same. By setting the length of the first support rod 211 to be less than the length of the second support rod 212, and the length of the second support rod 212 to be less than the length of the third support rod 213, the structure in this embodiment can reduce the manufacturing cost of the support device 100 compared to setting the lengths of the first support rod 211, the second support rod 212, and the third support rod 213 to be the same.

[0035] Please see Figure 1 and Figure 2 In one embodiment, the support device 100 further includes a first reinforcing rod 4 and a second reinforcing rod 5. One end of the first reinforcing rod 4 is connected to a first fixing rod 214, and the other end of the first reinforcing rod 4 is connected to the base 1. One end of the second reinforcing rod 5 is connected to a second fixing rod 312, and the other end of the second reinforcing rod 5 is connected to the base 1. By setting the first reinforcing rod 4 and the second reinforcing rod 5, the first reinforcing rod 4, the first fixing rod 214, and the base 1 form a triangular structure, and the second reinforcing rod 5, the second fixing rod 312, and the base 1 also form a triangular structure. This makes the connection between the first fixing rod 214 and the second fixing rod 312 and the base 1 more secure.

[0036] Please see Figure 1 and Figure 2 In one embodiment, the second support assembly 3 includes a connecting rod 313, a limiting rod 314, and a locking rod 315. Both ends of the connecting rod 313 are connected to two second fixed rods 312, respectively. The limiting rod 314 is rotatably mounted on the connecting rod 313. The locking rod 315 is located at the end of the limiting rod 314 away from the connecting rod 313 and is parallel to the connecting rod 313. The connecting rod 313, limiting rod 314, and locking rod 315 are all used to abut against the outer surface of the pressure loss chamber. Specifically, the pressure loss chamber is placed between the bases 1, and then the adjacent sides of the pressure loss chamber are pushed to abut against the connecting rod 313 and the limiting rod 314, respectively. Then, the limiting rod 314 is rotated so that the locking rod 315 on the side of the limiting rod 314 away from the connecting rod 313 abuts against the side of the pressure loss chamber opposite to the connecting rod 313. This securely locks the pressure loss chamber in place, preventing movement during testing and ensuring test accuracy.

[0037] Please see Figure 1 and Figure 2In one embodiment, the support device 100 further includes a first top rod 6, a second top rod 7, and a plurality of first reinforcing members 8. The two ends of the first top rod 6 are respectively connected to the top ends of two first fixing rods 214, the two ends of the second top rod 7 are respectively connected to the top ends of two second fixing rods 312, and the two ends of the first reinforcing members 8 are respectively connected to the first top rod 6 and the second top rod 7. The plurality of first reinforcing members 8 are spaced apart along a first direction. Specifically, one end of the first top rod 6 is connected to the top end of one first fixing rod 214, and then the other end of the first top rod 6 is connected to the top end of another first fixing rod 214. One end of the second top rod 7 is connected to the top end of one second fixing rod 312, and then the other end of the second top rod 7 is connected to the top end of another second fixing rod 312. Then, the two ends of the first reinforcing members 8 are respectively connected to the first top rod 6 and the second top rod 7. This integrates the first fixing rods 214 and 312 into a single unit, thereby increasing the stability of the first fixing rods 214 and 312.

[0038] Please see Figure 1 and Figure 2 In one embodiment, the base 1 includes a first base rod 11, a second base rod 12, and a plurality of second reinforcing members 13. Two first fixing rods 214 are respectively disposed at one end of the first base rod 11 and one end of the second base rod 12, and two second fixing rods 312 are respectively disposed at the other end of the first base rod 11 and the other end of the second base rod 12. The two ends of the second reinforcing members 13 are respectively connected to the first base rod 11 and the second base rod 12, and the plurality of second reinforcing members 13 are spaced apart along a second direction. By providing a plurality of second reinforcing members 13, the first base rod 11 and the second base rod 12 are made into a whole, which greatly improves the strength of the base 1 and increases the weight that the base 1 can bear.

[0039] Please see Figure 1 and Figure 2 In one embodiment, the base 1 further includes two connectors 14 and two widening rods 15. The connectors 14 have a first connecting hole and a second connecting hole. A first bottom rod 11 is installed in the first connecting hole of one connector 14, while a widening rod 15 is installed in the second connecting hole of the first connector 14. A second bottom rod 12 is installed in the first connecting hole of the other connector 14, while the other widening rod 15 is installed in the second connecting hole of the other connector 14. The two widening rods 15, the first bottom rod 11, and the second bottom rod 12 are arranged in parallel. By providing the widening rods 15, the width of the base 1 can be increased. The wider the base 1, the more stable the structure of the support device 100 will be. Furthermore, widening the base 1 allows for the addition of other functional components.

[0040] Please see Figure 2 and Figure 3In one embodiment, the base 1 further includes mounting bases 16 and casters 17. There are two casters 17 and two mounting bases 16. The two mounting bases 16 are rotatably mounted on the bottoms of the two connecting members 14, and the two casters 17 are rotatably mounted on the two mounting bases 16. By providing the casters 17, operators can easily push the support device 100, allowing it to move to a designated area. This makes the support device 100 in this embodiment usable in various scenarios.

[0041] Please see Figure 2 and Figure 3 In one embodiment, the base 1 further includes a brake pad 18, which is rotatably mounted on the mounting base 16. The brake pad 18 can rotate to abut against the caster 17 to prevent the caster 17 from rotating. By providing the brake pad 18, when the support device 100 moves to the required position, the brake pad 18 is rotated to abut against the caster 17, preventing the caster 17 from rotating. This prevents the support device 100 from moving due to sudden contact during testing, thus avoiding test errors; and also protects the safety of the operator during testing.
