Description

Technical Field

[0001] This application relates to the field of automotive lamp air tightness testing equipment, and more particularly to an air intake fixture for automotive lamp air tightness testing. Background Technology

[0002] Car lights play a role in nighttime illumination, traffic signals, and collision avoidance in bad weather while a car is in motion. Due to factors such as materials and manufacturing processes, there may be gaps in car lights, which can lead to airtightness issues.

[0003] Therefore, after the headlights are manufactured, they need to undergo airtightness testing. First, the air outlet of the airtightness testing device needs to align with the air inlet on the headlight to inject gas into the headlight. Then, a pressure sensor detects the pressure change inside the headlight after injection to determine if the airtightness is up to standard. However, different types of headlights vary in shape and size, and the location and size of the air inlet also differ. Therefore, different types of headlights require different models of airtightness testing devices. Existing airtightness testing devices have fixed outlet positions and sizes, which cannot meet the air intake requirements of different headlight types. Therefore, factories need to purchase multiple different types of airtightness testing devices simultaneously, resulting in a large footprint and high cost. Utility Model Content

The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0022] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0023] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0024] refer to Figure 1 An air intake fixture for testing the air tightness of a vehicle lamp according to a preferred embodiment of this application will be described in detail below. The air intake fixture for testing the air tightness of a vehicle lamp is adjacent to the processing worktable 80 and is used to input gas into the vehicle lamp 90 carried on the processing worktable 80 in order to test the air tightness of the vehicle lamp 90.

[0025] Specifically, the air intake fixture for testing the air tightness of vehicle lights includes a main body 100 and a testing unit 200.

[0026] refer to Figures 2 to 4The main body 100 of the equipment includes a support platform 10 and a conveyor mechanism 20. The support platform 10 has a high end portion 11 and a low end portion 12 below the high end portion 11, and the detection unit 200 is mounted on the high end portion 11. The conveyor mechanism 20 includes a drive component 21 and a mounting base 22. The drive component 21 is mounted on the high end portion 11, and the mounting base 22 is connected to the drive component 21. The drive component 21 is used to drive the mounting base 22 to move along a horizontal plane toward or away from the processing worktable 80.

[0027] The detection unit 200 includes a mounting base 30 and at least one detection mechanism 40. Each detection mechanism 40 includes a mounting body 41, an air supply component 42, and a linkage component 43. The mounting body 41 is mounted on the mounting base 30, and the mounting base 30 is detachably mounted on the high-end portion 11. The linkage component 43 is mounted on the mounting body 41 and is inserted into the mounting base 22, such that the drive component 21 drives the linkage component 43 to move through the mounting base 22. The air supply component 42 is slidably mounted vertically on the mounting body 41 and is connected to the linkage component 43. The linkage component 43 is configured to drive the air supply component 42 to move vertically when the mounting base 22 moves along a horizontal plane toward or away from the processing worktable 80. The air supply component 42 forms an air inlet 4201 and a downward-facing air outlet 4202. One end of the air supply component 42 forming the air inlet 4201 is connected to an air supply device via a pipe. The headlight 90 forms an upward-facing air inlet, and the air outlet 4202 formed by the air supply component 42 is vertically opposite to the air inlet formed by the headlight 90.

[0028] Specifically, when the gas supply component 42 moves downward so that the gas outlet 4202 aligns with the gas injection port formed by the headlight 90, gas is injected into the headlight 90 through the gas supply component 42. The air tightness of the headlight 90 is determined by detecting the pressure after gas injection. When the gas supply component 42 moves upward, the gas outlet 4202 separates from the gas injection port formed by the headlight 90, so that the air intake fixture used for headlight air tightness testing can test the next set of headlights 90.

[0029] It is worth mentioning that, since the linkage component 43 and the mounting base 22 are connected by a plug-in joint, after the assembly base 30 and the support platform 10 are disassembled, the operator can directly separate the testing unit 200 from the equipment body 100, simplifying the disassembly steps between the testing unit 200 and the equipment body 100, improving the disassembly efficiency of the testing unit 200, and also simplifying the installation work of the testing unit 200. It is understood that different vehicle models use different headlight models; the operator only needs to replace the testing unit 200 according to the type of headlight 90 carried on the processing workbench 80, without needing to replace the entire air intake fixture used for headlight airtightness testing.

[0030] Preferably, the mounting base 22 forms a first mounting structure 2201, and the linkage component 43 forms a first connecting structure 4301. Either the first mounting structure 2201 or the first connecting structure 4301 is implemented as a slot, and the other as a pin. The linkage component 43 is detachably mounted to the linkage component 43 by means of a plug-in connection between the first connecting structure 4301 and the first mounting structure 2201.

[0031] Preferably, the detection unit 200 includes a plurality of detection mechanisms 40, which are installed at intervals on the mounting base 30. Each detection mechanism 40 corresponds to one of the vehicle lights 90, so that the air intake fixture for detecting the air tightness of the vehicle lights can supply air to a plurality of vehicle lights 90 at the same time.

[0032] In one embodiment, the conveyor mechanism 20 is provided with a plurality of mounting seats 22 and a plurality of driving components 21, with the mounting seats 22 spaced apart from each other on the high-end portion 11. The driving components 21 respectively drive the plurality of mounting seats 22 to move, and the linkage components 43 of each of the plurality of detection mechanisms 40 are respectively connected to the plurality of mounting seats 22, so that the plurality of driving components 21 respectively drive the corresponding detection mechanism 40 to operate through the corresponding mounting seat 22. That is, the corresponding number of detection mechanisms 40 can be selected to deliver gas to the vehicle lamp 90 according to actual usage requirements.

[0033] In another embodiment, the conveyor mechanism 20 is provided with a mounting base 22 and a driving component 21. The linkage components 43 of each of the plurality of detection mechanisms 40 are all connected to the mounting base 22, so that one driving component 21 drives the operation of multiple detection mechanisms 40 simultaneously through the mounting base 22, thereby reducing the number of driving components 21 and reducing the manufacturing cost of the main body of the equipment 100.

[0034] In one embodiment, the mounting body 41 and the mounting base 30 are integrally formed by casting.

[0035] In another embodiment, the mounting body 41 is bolted to the mounting base 30, and the operator can remove the bolts to repair, adjust and replace the detection mechanism 40.

[0036] Preferably, the outer peripheral wall of the driving component 21 forms a groove, which extends parallel to the driving direction of the driving component 21. The mounting base 22 is slidably mounted in the groove to allow the mounting base 22 to move stably.

[0037] As an example, the drive component 21 is implemented to include a cylinder.

[0038] refer to Figure 2 and Figure 5 Preferably, the linkage component 43 includes a first linkage member 431 and a second linkage member 432, wherein the first linkage member 431 forms the first connection structure 4301 and is inserted into the mounting base 22. The second linkage member 432 is rotatably mounted on the mounting body 41, and has a pressure end 4321 and a traction end 4322, such that when either the pressure end 4321 or the traction end 4322 rises, the other falls. Either the first linkage member 431 or the traction end 4322 forms a sliding groove 433, and the other forms a plugging protrusion 434. The first linkage member 431 is slidably mounted on the traction end 4322 such that the plugging protrusion 434 is inserted into the sliding groove 433, and when the first linkage member 431 moves horizontally, the first linkage member 431 drives the second linkage member 432 to rotate through the cooperation of the plugging protrusion 434 and the sliding groove 433. The pressure-applying end 4321 is slidably mounted on the gas delivery component 42, so that the second linkage 432 can drive the gas delivery component 42 to move vertically.

[0039] It is worth mentioning that the extending direction of the sliding groove 433 is parallel to the direction in which the second linkage 432 extends from the traction end 4322 to the pressure end 4321.

[0040] In one embodiment, the angle between the extending direction of the sliding groove 433 and the vertically downward direction is an obtuse angle. Specifically, when the mounting base 22 drives the first linkage member 431 to move along the horizontal plane away from the headlight 90, the first linkage member 431 drives the traction end 4322 to move upward through the cooperation between the insertion protrusion 434 and the sliding groove 433, so that the pressure end 4321 moves downward and pushes the air supply component 42 to move vertically closer to the headlight 90, so that the air outlet 4202 aligns with the air inlet. When the mounting base 22 drives the first linkage member 431 to move along the horizontal plane toward the headlight 90, the first linkage member 431 drives the traction end 4322 to move downward through the cooperation between the plug-in protrusion 434 and the sliding groove 433, so that the pressure end 4321 moves upward and pulls the air supply component 42 away from the headlight 90 vertically, so that the air outlet 4202 is separated from the air inlet.

[0041] In another embodiment, the angle between the extending direction of the sliding groove 433 and the vertically downward direction is acute. Specifically, when the mounting base 22 drives the first linkage member 431 to move along the horizontal plane toward the headlight 90, the first linkage member 431 drives the traction end 4322 to move upward through the cooperation between the insertion protrusion 434 and the sliding groove 433, so that the pressure end 4321 moves downward and pushes the air supply component 42 toward the headlight 90 vertically, so that the air inlet 4201 aligns with the air injection port. When the mounting base 22 drives the first linkage member 431 to move along the horizontal plane away from the headlight 90, the first linkage member 431 drives the traction end 4322 to move downward through the cooperation between the plug-in protrusion 434 and the sliding groove 433, so that the pressure end 4321 moves upward and pulls the air supply component 42 away from the headlight 90 vertically, so that the air inlet 4201 is separated from the air injection port.

[0042] refer to Figure 3 Preferably, the mounting body 41 forms a first guide structure 4101, which extends along a driving direction parallel to the driving component 21. The first linkage member 431 is slidably mounted on the first guide structure 4101, which defines the moving direction of the first linkage member 431.

[0043] As an example, the first guide structure 4101 is implemented as a guide rail.

[0044] refer to Figure 2Preferably, the mounting body 41 forms a second guide structure 4102, which extends vertically. The gas delivery component 42 is slidably mounted on the second guide structure 4102, and the gas delivery component 42 is used to define the direction of movement of the gas delivery component 42.

[0045] As an example, the second guide structure 4102 is implemented as a guide rail.

[0046] refer to Figure 5 In one embodiment, the gas delivery component 42 forms a second mounting structure 4203, and the second linkage 432 forms a second connecting structure 43201 at the pressure end 4321. The gas delivery component 42 is slidably mounted on the pressure end 4321 in such a way that the second mounting structure 4203 and the second connecting structure 43201 are inserted into each other.

[0047] As an example, either the second mounting structure 4203 or the second connecting structure 43201 is implemented as a groove, and the other is implemented as a pin.

[0048] Furthermore, each of the aforementioned testing mechanisms 40 includes a clamping member 44, which is installed on the mounting body 41. The vehicle lamp 90 has an abutment wall, and the bottom wall of the clamping member 44 abuts against the abutment wall of the vehicle lamp 90, so that the clamping member 44 fixes the vehicle lamp 90 on the processing worktable 80 by abutting against the abutment wall, thereby preventing the vehicle lamp 90 from shaking and ensuring that the air supply component 42 can smoothly connect with the air injection port formed by the vehicle lamp 90.

[0049] refer to Figure 2 and Figure 3 Furthermore, the air intake fixture for testing the air tightness of vehicle lights includes a locking mechanism 50.

[0050] The mounting base 30 forms a mounting hole 301, and the support platform 10 forms a mating hole 101. The mounting base 30 is placed on the top wall of the high end part 11 with the mounting hole 301 and the mating hole 101 aligned. The locking mechanism 50 is installed in the mounting hole 301 and the mating hole 101 in a way that can be unlocked.

[0051] As an example, the locking mechanism 50 is implemented as a bolt, the inner wall of the mounting hole 101 is formed with an internal thread, and the locking mechanism 50 passes through the mounting hole 301 from top to bottom and is threadedly connected to the mounting hole 101.

[0052] Furthermore, the mounting base 30 also has two handles 31, which are located at both ends of the mounting base 30 respectively, to provide a gripping part for the staff to carry the detection unit 200.

[0053] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
