[0002] Anti-fog structures for headlights are a crucial component of automotive lighting systems, ensuring clear vision for the driver and enhancing driving safety, especially in adverse weather conditions. Ventilation holes and desiccants are the primary means of preventing fogging in headlights. Condensation managers, as integrated vents and desiccants, have been widely used since their launch. However, during the current end-of-line airtightness test for headlights containing condensation managers, the tooling used to press and seal the condensation manager causes the condensation manager to shift toward the lamp housing, reducing the gap between the two. This allows the airtightness test to pass, but does not reflect the actual assembly state. Consequently, during use, a headlight may pass the airtightness test at the end of the line but fail the watertightness test. To address this issue, how to ensure that the condensation manager is sealed during the airtightness test and accurately reflect the actual airtightness condition of the headlight has become a pressing technical challenge for those skilled in the art.

[0040] The core of the utility model is to disclose an auxiliary component for air tightness detection of vehicle lamps, so as to achieve sealing of the condensation manager of the vehicle lamps during air tightness detection and accurately reflect the actual air tightness condition of the vehicle lamps.

[0041] Another core of the present utility model is to disclose a vehicle lamp air tightness detection system including the above-mentioned vehicle lamp air tightness detection auxiliary component.

[0042] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the scope of the utility model as set forth in the claims. Furthermore, the entire contents of the components described in the following embodiments are not necessarily required to provide the solutions described in the claims. It should be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings. The embodiments and features of the embodiments of the present utility model may be combined with one another unless there is a conflict.

[0043] Combine Figures 1-11 The vehicle lamp air tightness detection auxiliary component disclosed in the present invention includes a sealing portion 110 and a connecting portion 100. The sealing portion 110 is made of a soft rubber material, and a sealing opening 111 is provided on one side thereof for the condensation manager 200 to be embedded; the connecting portion 100 is made of a hard rubber material and is connected to the open side of the sealing portion 110, and the connecting portion 100 is provided with an avoidance hole connected to the sealing opening 111, and the avoidance hole is used for the condensation manager 200 to pass through and enter the sealing opening 111.

[0044] The sealing mechanism 310 installs the headlight airtightness detection auxiliary component on the condensation manager 200 by moving the connecting part 100, and makes the sealing part 110 made of soft rubber material seal the condensation manager 200 to ensure the sealing effect. At the same time, the sealing part 110 can adaptively deform to avoid excessive compression on the condensation manager 200, affecting the actual assembly of the condensation manager 200 and the headlight; the connecting part 100 made of hard rubber material can ensure the shape of the sealing part 110 and is convenient for connection with the sealing mechanism 310.

[0045] Compared with the existing technology, the connecting part 100 and the sealing part 110 of the auxiliary component for air tightness detection of vehicle lamps disclosed in the utility model are made of hard rubber and soft rubber materials respectively, which facilitates assembly and has a sealing effect. It can achieve reliable sealing of the condensation manager 200 during air tightness detection and accurately reflect the actual air tightness condition of the vehicle lamp.

[0046] Furthermore, in order to optimize the sealing effect, the diameter of the sealing port 111 gradually decreases along the opening of the sealing port 111 toward the bottom. During the assembly process, as the condensation manager 200 gradually enters the sealing port 111, the sealing port 111 can gradually clamp the condensation manager 200 to prevent the two from loosening.

[0047] In order to avoid damage to the breathable membrane 202 of the condensation manager 200, Figure 1 and Figure 2An annular boss is protruding from the bottom wall of the sealing port 111, which is used to abut against the end face of the cylinder of the condensation manager 200. The breathable membrane 202 of the condensation manager 200 can be embedded in the inner circle of the annular boss, and the thickness of the annular boss is greater than the thickness of the breathable membrane 202, which can prevent the breathable membrane 202 from directly contacting the bottom wall of the sealing port 111 and causing damage.

[0048] The annular boss and the sealing portion 110 may be an integrated structure and may be integrally formed by injection molding using a soft rubber material.

[0049] Combine Figure 6 and Figure 7 A positioning protrusion 201 is provided on the outer wall of the condensation manager 200. In order to realize the positioning assembly of the condensation manager 200 and the blocking port 111, a mounting protrusion 120 is provided on the circumferential outer wall of the blocking portion 110. The mounting protrusion 120 is provided with a first positioning groove connected to the blocking port 111, and the connecting portion 100 is provided with a second positioning groove 101 connected to the first positioning groove. The first positioning groove and the second positioning groove 101 are for the positioning protrusion 201 to pass through, thereby realizing positioning assembly.

[0050] Specifically, the mounting protrusions 120 may be arranged at equal intervals around the circumferential outer wall of the blocking portion 110, and the first positioning grooves and the second positioning grooves 101 may each correspond one-to-one to the mounting protrusions 120. Furthermore, the mounting protrusions 120 may be made of a soft rubber material, and the blocking portion 110 and the mounting protrusions 120 may be an integral structure and integrally formed by injection molding.

[0051] The sealing part 110 and the connecting part 100 can be an integral structure or a split structure. When it is a split structure, the two can be connected by gluing to ensure sealing; when it is an integral structure, the sealing part 110 and the connecting part 100 can be integrally prepared and formed by two-color injection molding or other methods, which is simple in process and convenient in production.

[0052] A positioning portion may be provided on one side of the connecting portion 100, and the positioning portion is used to be fitted and matched with the blocking mechanism 310. Specifically, the positioning portion may be a protrusion structure or a groove structure.

[0053] Combine Figure 12 The vehicle lamp air tightness testing system disclosed in the present invention includes a sealing mechanism 310 and the aforementioned vehicle lamp air tightness testing auxiliary component. The sealing mechanism 310 includes a telescopic bracket connected to the connecting portion 100, capable of adjusting its telescopic length. Specifically, the telescopic bracket and connecting portion 100 can be detachably connected using a bolt connection or other method. Since the aforementioned vehicle lamp air tightness testing auxiliary component is included, the system also possesses the aforementioned structure and beneficial effects, and will not be further elaborated here.

[0054] In one embodiment, combining Figure 12 The vehicle lamp air tightness testing system includes a mounting frame 300 and multiple lamp fixing mechanisms 320. The blocking mechanism 310 and the lamp fixing mechanisms 320 are both mounted on the mounting frame 300. The lamp fixing mechanisms 320 are used to support and position the lamps to facilitate air tightness testing. The lamp fixing mechanisms 320 include telescopic brackets to facilitate adjustment of the specific support position based on the lamp model. Other structural features are referenced in the prior art and will not be further described here.

[0055] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Specific technical means in some embodiments may be incorporated in part or in whole into another embodiment, unless expressly excluded by another embodiment.
