Description

Technical Field

[0001] This application relates to the field of air duct testing, and more particularly to an automotive air duct testing device. Background Technology

[0002] The defrosting duct is an important component of the vehicle's air conditioning defrosting and defogging system. It is usually located inside the car's center console, near the windshield. It is used to guide the hot air generated by the air conditioning unit to the windshield to melt the frost or ice that has accumulated on the outside of the windshield. At the same time, it prevents fogging when the surface temperature of the windshield is lower than the temperature of the air inside the car, thus improving the driver's driving safety.

[0003] Reference Figure 1 The defrosting duct includes a duct body 1, with a guide channel 11 on one end face. The guide channel 11 extends through the duct body 1 along its length. One end of the duct body 1 is used to connect to the air outlet of the air conditioning unit, and the other end faces the windshield. The air discharged from the air outlet of the air conditioning unit is guided by the guide channel 11 and blown onto the windshield. Multiple limiting blocks 2 are evenly connected to the outer wall of the duct body 1 at intervals. The limiting blocks 2 are located at the ends of the duct body 1 and are used to limit the connection of the air outlet of the air conditioning unit.

[0004] Reference Figure 1 The limiting insert 2 includes a fixed section 21, an abutting section 22, and an embedding section 23. The fixed section 21, abutting section 22, and embedding section 23 are connected at their ends in sequence. Each of the fixed section 21, abutting section 22, and embedding section 23 is a strip plate. The length direction of the fixed section 21 is perpendicular to the length direction of the abutting section 22, and the end of the abutting section 22 protrudes from the end face of the air duct body 1. The length direction of the embedding section 23 is parallel to the length direction of the fixed section 21, and the end of the embedding section 23 extends away from the fixed section 21. Two fixing plates 3 and two fixing plates 4 are connected to the ends of the air duct body 1 away from the limiting insert 2. The fixing plates 3 and 4 are located on both sides of the air duct body 1, and the fixing plates 3 and the limiting insert 2 are located on the same side of the air duct body 1.

[0005] Reference Figure 1 The first fixing plate 3 has two assembly slots 31 on its end face, which penetrate the first fixing plate 3; the second fixing plate 4 has an assembly slot 41 on its end face, which penetrates the second fixing plate 4.

[0006] When the staff installs the air duct body 1 on the air conditioning unit, they need to first embed the limiting block 2 into the air inlet end face of the air conditioning unit to form a preliminary limit. When the length of the abutment section 22 is too long or too short, the air duct body 1 cannot be completely embedded into the air outlet end of the air conditioning unit, causing the air discharged from the air outlet end of the air conditioning unit to easily overflow from the connection between the air conditioning unit and the air duct body 1, thereby reducing the air guiding efficiency of the air duct body 1. Summary of the Invention

[0007] To improve the connection between the air duct body and the air conditioning unit, this application provides an automotive air duct testing device.

[0008] This application provides an automotive air duct testing device, which adopts the following technical solution:

[0009] An automotive air duct testing device includes a base and a support column connected to the base. A measuring component is connected to the support column for detecting the length of an abutment section. The measuring component includes an abutment post, a transmission component, and a clamping post. The abutment post is slidably connected to the end face of the support column, and the end of the abutment post protruding from the end face of the support column is used to abut against the end face of an embedded section. The clamping post is slidably connected to the end face of the support column, and the sliding direction of the clamping post is parallel to the sliding direction of the abutment post. The end of the clamping post protruding from the end face of the support column is used to clamp against the end face of a fixed section. The transmission component... The transmission component receives the power from the abutment column and drives the abutment column to slide. A limiting block is placed on the top surface of the support column, and the top surface of the support column abuts against the end face of the abutment section to form a limit. The end face of the abutment column and the end face of the abutment column are located on both sides of the limiting block. The end face of the embedded section abuts against the end face of the abutment column and drives the end face of the abutment column to slide towards the support column. The transmission component receives the power from the abutment column and drives the abutment column to slide towards the support column. When the end face of the abutment column abuts against the end face of the fixed section, the length of the abutment section is qualified. When the end face of the abutment column does not abut against the end face of the fixed section, the length of the abutment section is unqualified.

[0010] By adopting the above technical solution, the staff places the duct body on the end face of the base, the top surface of the support column abuts against the end face of the abutting section to form a limit, the end face of the abutting column abuts against the end face of the embedded section, and drives the end face of the abutting column to slide towards the support column. The transmission component receives the power of the abutting column and drives the abutting column to slide towards the support column. When the end face of the abutting column abuts against the end face of the fixed section, the length of the abutting section is qualified. When the end face of the abutting column does not abut against the end face of the fixed section, the length of the abutting section is unqualified. This realizes the detection of the limit block, improves the connection stability between the duct body and the air conditioning unit, makes it less likely for the air discharged from the air conditioning unit to overflow from the connection between the air conditioning unit and the duct body, and improves the air guiding efficiency of the duct body.

[0011] Optionally, an elastic element is connected between the support column and the abutment column, and the elastic force of the elastic element causes the end of the abutment column to protrude from the end face of the support column.

[0012] By adopting the above technical solution, when the limiting insert disengages from the support column, the clamping force of the embedded section on the abutment column disappears, and the elastic force of the elastic element drives the abutment column to slide away from the support column. The end of the abutment column protrudes from the end face of the support column, thereby realizing the reset of the abutment column. There is no need for the staff to manually reset the abutment column, thereby improving the efficiency of the staff in inspecting the automotive air duct.

[0013] Optionally, the support column has a clamping cavity on its end face facing the limiting insert. The clamping cavity extends through the support column in a direction away from the limiting insert. The clamping column is slidably connected within the clamping cavity. A warning element is connected to the clamping column. The warning element is used to detect when the end face of the clamping column is pressed against the end face of the fixed section. A warning cavity for accommodating the warning element is formed on the outer wall of the clamping column. The warning cavity is located on the side of the clamping column away from the limiting insert. The inner wall of the clamping cavity seals the warning cavity. The warning element includes an elastic element and a warning block. The two ends of the elastic element are connected to the end of the warning block and the inner wall of the warning cavity in the elastic direction. The elastic element has a tendency to elastically drive the end of the warning block to protrude from the end face of the clamping column. When one end of the clamping column is pressed against the end face of the fixed section, the other end of the clamping column protrudes from the end face of the support column. The sealing effect of the inner wall of the clamping cavity on the warning cavity disappears, and the elastic element pushes the warning block to protrude from the end face of the clamping column.

[0014] By adopting the above technical solution, when the staff places the duct body on the base, the top surface of the support column abuts against the end face of the abutment section to form a preliminary limit, the end face of the embedded section abuts against the end face of the abutment column, and drives the abutment column to slide closer to the support column. The transmission component receives the power of the abutment column and drives the abutment column to slide closer to the support column. When one end of the abutment column abuts against the fixed section surface, the other end of the abutment column protrudes from the end face of the support column, and the sealing effect of the inner wall of the abutment cavity on the warning cavity disappears. The elastic component drives the warning block to protrude from the end face of the abutment column, so that the staff can directly observe the abutment situation between the abutment column and the fixed section without the need for the staff to switch perspectives to observe the abutment surface between the abutment column and the fixed section, further improving the detection efficiency of the duct body.

[0015] Optionally, a fixing component is connected to the base. The fixing component is used to limit the limiting insert to the top surface of the support column. The fixing component includes a driving component and a driving plate. The driving component is connected to the base, and the end of the driving plate is connected to the moving end of the driving component. The driving component drives the driving plate to move closer to or away from the support column. When the limiting insert is located at the end face of the support column, the driving component drives the driving plate to rotate in the direction closer to the support column, and the end face of the driving plate abuts against the bottom wall of the air duct body to form a limiting position.

[0016] By adopting the above technical solution, the staff places the limiting block on the top surface of the support column, and the end face of the abutting section abuts against the top surface of the support column to achieve initial limiting. The driving component drives the driving plate to rotate in the direction closer to the support column, and the end face of the driving plate abuts against the bottom wall of the air duct body to form a limiting, so that the limiting block is not easy to detach from the end face of the support column, thereby improving the detection accuracy of the measuring component on the air duct body.

[0017] Optionally, a limiting post is connected to the base, and a limiting component is connected to the limiting post. The limiting component is used to limit the air duct body on the base. The limiting component includes a second driving member and a limiting plate. The second driving member is connected to the top surface of the limiting post, and the end of the limiting plate is connected to the moving end of the second driving member. The second driving member drives the limiting plate to move closer to or away from the limiting post. The end face of the limiting plate facing the limiting post is used to abut against one end face of the fixing plate. When one end face of the fixing plate abuts against the end face of the limiting plate, the second driving member drives the limiting plate to slide closer to the limiting post, and one end face of the fixing plate abuts against the end face of the limiting post to form a fixation.

[0018] By adopting the above technical solution, when the fixing plate is placed on the end face of the limiting plate, the driving component 2 drives the fixing plate to slide towards the limiting post. The end face of the fixing plate abuts against the end face of the limiting post to form a fixation, making it difficult for the air duct body to shift on the base, thereby improving the detection accuracy of the limiting insert.

[0019] Optionally, the end face of the limiting plate facing the base is connected to an abutment block, which is used to embed into one of the assembly slots. When the end face of the fixing plate abuts against the end face of the limiting plate, the outer wall of the abutment block abuts against the assembly slot to form a limit.

[0020] By adopting the above technical solution, when the fixing plate is placed on the end face of the limiting plate, the abutment block is embedded in one of the assembly slots, and the outer circumferential wall of the abutment block abuts against the inner wall of the assembly slot, making it difficult for the fixing plate to detach from the end face of the limiting plate, thereby achieving the limiting of the fixing plate on the limiting plate.

[0021] Optionally, a positioning component is connected to the limiting post. The positioning component is used to detect the first assembly slot. The positioning component includes a positioning rod, which is slidably connected to the limiting post. The sliding direction of the positioning rod is towards or away from the limiting plate. When the first fixing plate abuts against the end face of the limiting post, the positioning rod slides towards the first fixing plate. The end of the positioning rod passes through another first assembly slot, and the position of the first assembly slot on the first fixing plate is qualified.

[0022] By adopting the above technical solution, one end face of the fixed plate abuts against the end face of the limiting post, and the outer circumferential wall of the abutting block abuts against the inner circumferential wall of one of the assembly slots, thereby improving the limiting stability of the air duct body on the base. The operator drives the positioning rod to slide towards the fixed plate. When the end of the positioning rod passes through another assembly slot, the position of the assembly slot on the fixed plate is qualified. When the end of the positioning rod cannot pass through another assembly slot, the position of the assembly slot on the fixed plate is unqualified. This realizes the detection of the assembly slot on the air duct body and improves the connection stability of the air duct body on the air conditioning unit.

[0023] Optionally, the positioning component further includes a second elastic element, the two ends of which are connected one-to-one to the limiting post and the positioning rod in the elastic direction. The second elastic element has the tendency to elastically drive the positioning rod to slide away from the limiting plate.

[0024] By adopting the above technical solution, when the positioning column finishes detecting the position of the assembly slot one on the fixed plate one, the operator releases the positioning column, and the elastic component two drives the positioning column to slide away from the limiting plate, thereby realizing the automatic reset of the positioning rod without the need for manual reset by the operator, thus improving the operator's detection efficiency of the air duct body.

[0025] Optionally, a connecting plate is connected to the base. The connecting plate is located on the side of the base away from the support column. When the outer wall of the limiting insert abuts against the end face of the support column, the connecting plate is located on the side of the air duct body close to the second fixing plate. A connecting rod is slidably connected to the end face of the connecting plate. The sliding direction of the connecting rod is towards or away from the second fixing plate. When the end of the connecting rod passes through the second assembly groove, the position of the second assembly groove on the second fixing plate is qualified.

[0026] By adopting the above technical solution, the operator confines the duct body to the base, and the connecting rod is located on the side of the duct body closer to the second fixed plate. The operator drives the connecting rod to slide towards the second fixed plate. When the end of the connecting rod passes through the second assembly hole, the position of the second assembly hole on the second fixed plate is qualified. When the end of the connecting rod cannot pass through the second assembly hole, the position of the second assembly hole on the second fixed plate is unqualified. This improves the detection accuracy of the duct body and further enhances the connection stability between the duct body and the air conditioning unit.

[0027] Optionally, a spring element three is connected between the connecting plate and the connecting rod, and the spring element three has the tendency to elastically drive the connecting rod to slide away from the fixed plate two.

[0028] By adopting the above technical solution, when the inspection of the connecting rod on the mounting slot 2 of the fixed plate 2 is completed, the operator releases the connecting rod, and the elastic component 3 drives the connecting rod to slide away from the fixed plate 2, thereby realizing the automatic reset of the connecting rod without the need for manual reset by the operator, thus improving the inspection efficiency of the air duct body.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The setting of the abutment column, transmission component and clamping column realizes the detection of the limit block, so that the air discharged from the air conditioning unit is not easy to overflow from the connection between the air conditioning unit and the air duct body, and improves the air duct body's air guiding efficiency.

[0031] 2. The setting of the elastic component and the warning block allows the staff to directly observe the clamping situation between the clamping column and the fixed section without the staff having to switch perspectives to observe the contact surface between the clamping column and the fixed section, thus further improving the inspection efficiency of the air duct body.

[0032] 3. The positioning rod is set to detect the assembly slot 1 on the air duct body, thereby improving the connection stability of the air duct body on the air conditioning unit. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0041] This application discloses an automotive air duct testing device. (Refer to...) Figure 2 and Figure 3 An automotive air duct testing device includes a base 5, a support column 6 connected to the end face of the base 5, and a measuring component 7 connected to the support column 6.

[0042] Reference Figure 3 and Figure 4 The end face of the support column 6 is used to abut against the outer wall of the limiting insert 2 to form a limit, and the measuring component 7 is used to detect whether the length of the abutment section 22 is qualified.

[0043] Reference Figure 2 and Figure 4In this embodiment, there are four support columns 6. The base 5 is a cuboid. The ends of the four support columns 6 are welded and fixed to the end face of the base 5 at even intervals. The arrangement direction of the support columns 6 is parallel to the length direction of the base 5. Each support column 6 corresponds to a limiting block 2. Each support column 6 includes an extension section 61 and a detection section 62. The end of the extension section 61 is welded and fixed to the end of the detection section 62. The other end of the extension section 61 is connected to the end face of the base 5. A stepped surface 63 is formed at the connection between the extension section 61 and the detection section 62. The stepped surface 63 abuts against the outer wall of the limiting block 2 to form a limiting effect.

[0044] Reference Figure 3 and Figure 4 A clamping cavity 64 is provided on the end face of the detection section 62 facing the step surface 63. The clamping cavity 64 is used to accommodate the measuring component 7. The clamping cavity 64 penetrates the outer wall of the detection section 62 in a direction away from the step surface 63. The measuring component 7 includes an abutment post 71, a transmission member 72, and a clamping post 73. The abutment post 71 is slidably connected to the inner wall of the clamping cavity 64. The sliding direction of the abutment post 71 is towards or away from the step surface 63. The end of the abutment post 71 facing the step surface 63 is used to abut against the outer wall of the abutment section 22. The clamping post 73 is slidably connected to the inner wall of the clamping cavity 64. The sliding direction of the clamping post 73 is parallel to the sliding direction of the abutment post 71. The end of the clamping post 73 facing the step surface 63 is used to clamp against the outer wall of the fixed section 21. The transmission member 72 is used to receive the power of the abutment post 71 and drive the clamping post 73 to slide.

[0045] Reference Figure 3 and Figure 4 An elastic element 8 connects the abutment post 71 and the detection section 62. The elastic element 8 can be a compression spring or a torsion spring. In this embodiment, the elastic element 8 is a compression spring and has a certain deformation capability. The two ends of the elastic element 8 in the elastic force direction are welded and fixed to the end of the abutment post 71 and the inner wall of the pressing cavity 64. The elastic force direction of the elastic element 8 is parallel to the sliding direction of the abutment post 71. The elastic element 8 has the elastic force to drive the abutment post 71 to slide away from the pressing cavity 64, and the end of the abutment post 71 tends to protrude from the end face of the detection section 62.

[0046] Reference Figure 3 and Figure 4The clamping column 73 includes a clamping section 731, a connecting section 732, an extension section 733, a warning section 734, and a driving section 735. The clamping section 731, the connecting section 732, the extension section 733, the warning section 734, and the driving section 735 are welded and fixed at their ends in sequence. The axis of the drive section 735 and the axis of the abutment post 71 are parallel to each other, and the outer wall of the drive section 735 is slidably connected to the inner wall of the abutment cavity 64; the axis of the warning section 734 is perpendicular to the axis of the drive section 735, and the warning section 734 is located on the side of the detection section 62 away from the step surface 63; the axis of the extension section 733 is parallel to the axis of the drive section 735, and the extension section 733 is slidably connected to the inner wall of the abutment cavity 64; the axis of the connecting section 732 is parallel to the axis of the warning section 734, and the connecting section 732 protrudes from the outer wall of the detection section 62 and faces the step surface 63; the axis of the abutment section 731 is parallel to the axis of the extension section 733, the abutment section 731 protrudes from the outer wall of the detection section 62 and faces the step surface 63, and the end of the abutment section 731 away from the connecting section 732 is used to abut against the outer wall of the fixing section 21.

[0047] Reference Figure 3 and Figure 4 The transmission component 72 includes a first gear 721 and a second gear 722. The first gear 721 is coaxially welded and fixed to the second gear 722. The ends of the first gear 721 and the second gear 722 that are far apart from each other are rotatably connected to the inner wall of the abutment cavity 64. The diameter of the first gear 721 is larger than the diameter of the second gear 722. The first gear 721 is located between the drive section 735 and the extension section 733. The end face of the drive section 735 facing the first gear 721 is provided with a tooth groove 7351 that matches the wheel surface of the first gear 721. The inner wall of the tooth groove 7351 meshes with the first gear 721.

[0048] Reference Figure 3 and Figure 4 The abutment post 71 is located on the side of the second gear 722 near the drive section 735. The end face of the abutment post 71 facing the second gear 722 has a toothed groove 711 that matches the wheel surface of the second gear 722. The inner wall of the toothed groove 711 meshes with the second gear 722. When the outer wall of the limiting insert 2 abuts the step surface 63, the end of the abutment post 71 abuts the end face of the abutment section 22, driving the abutment post 71 to slide away from the step surface 63. The first gear 721 and the second gear 722 rotate, driving the clamping section 731 to slide closer to the step surface 63. When the end of the clamping section 731 abuts the end face of the fixing section 21, the length of the limiting insert 2 is qualified; when the end of the clamping section 731 does not abut the end face of the fixing section 21, the length of the limiting insert 2 is unqualified.

[0049] Reference Figure 4 and Figure 5A warning element 9 is connected to the clamping post 73. The warning element 9 is used to detect whether the end of the clamping section 731 is pressed against the end face of the fixed section 21. The end face of the warning section 734 near the extension section 733 has a warning cavity 7341. When the extension section 733 slides towards the step surface 63, the inner wall of the clamping cavity 64 seals the warning cavity 7341. When the end of the clamping section 731 abuts against the end face of the fixed section 21, it drives the extension section 733 to slide away from the step surface 63, and the warning section 734 protrudes from the end face of the support post 6, and the sealing effect of the inner wall of the clamping cavity 64 on the warning cavity 7341 disappears.

[0050] Reference Figure 5 The warning element 9 includes an elastic element 91 and a warning block 92. The elastic element 91 can be a compression spring or a torsion spring. In this embodiment, the elastic element 91 is a compression spring and has a certain deformation capability. The two ends of the elastic element 91 in the elastic direction are welded and fixed to the end of the warning block 92 and the inner wall of the warning cavity 7341. The elastic direction of the elastic element 91 is parallel to the axis of the warning segment 734. The elastic element 91 has the elastic force to drive the warning block 92 to slide away from the warning segment 734, and the end of the warning block 92 tends to protrude from the end face of the warning segment 734.

[0051] Reference Figure 4 and Figure 5 The end of the warning block 92 away from the elastic element 91 is provided with a guide surface 921. The guide surface 921 is in the shape of a rounded protrusion. When the staff squeezes the warning section 734 and drives the warning section 734 to slide towards the step surface 63, the guide surface 921 abuts against the inner wall of the clamping cavity 64, and the warning block 92 slides along the guide surface 921 towards the warning cavity 7341, thereby realizing the reset of the warning block 92.

[0052] Reference Figure 2 and Figure 4 Two fixing components 10 are connected to the base 5. The two fixing components 10 are located on both sides of the direction in which the support columns 6 are arranged. The fixing components 10 are used to limit the limiting insert 2 on the stepped surface 63. The fixing components 10 include a drive component 101 and a drive plate 102. The drive component 101 includes a vertical quick clamp 1011 and a fixing block 1012. The end of the fixing block 1012 is welded and fixed to the base 5. The vertical quick clamp 1011 is fixed to the outer wall of the fixing block 1012 by screws. The moving end of the vertical quick clamp 1011 faces the support column 6.

[0053] Reference Figure 2 and Figure 4One end of the drive plate 102 is welded and fixed to the moving end of the vertical quick clamp 1011, and the other end of the drive plate 102 is used to abut against the bottom of the air duct body 1. When the outer wall of the limiting insert 2 abuts against the step surface 63, the moving end of the vertical quick clamp 1011 drives the drive plate 102 to rotate toward the support column 6, and the outer wall of the drive plate 102 abuts against the bottom of the air duct body 1 to form a fixation.

[0054] Reference Figure 2 The base 5 has two limiting posts 12 connected to its end face. The two limiting posts 12 are located on both sides of the direction of the support posts 6. The limiting posts 12 are located on the side of the support posts 6 away from the step surface 63.

[0055] Reference Figure 2 The limiting post 12 includes an extension 121, a limiting part 122, and a connecting part 123. The extension 121, the limiting part 122, and the connecting part 123 are sequentially welded to their ends. The axis of the extension 121 is parallel to the axis of the support post 6.
