Abstract
Description
Technical Field
[0001] This invention relates to the field of lamp adjustment module technology, specifically to an automotive headlight lens adjustment linkage module. Background Technology
[0002] In the continuous development of the automotive industry, vehicle lights, as a key component ensuring driving safety, are receiving increasing attention for the stability and accuracy of their illumination effect. The vehicle headlight adjustment module, as the core device for adjusting the headlight angle, directly impacts driving safety at night or in complex road conditions.
[0003] However, existing automotive headlight adjustment modules still face numerous unresolved issues in practical applications. Regarding angle adjustment, current modules typically use a screwdriver to adjust the gears and utilize transmission gears and a linkage rack and pinion to achieve synchronous adjustment of multiple lens modules. However, this adjustment method lacks an effective limiting mechanism, resulting in poor angle fixation of the lens modules. During vehicle operation, various vibrations are inevitable, such as continuous vibrations from road bumps and resonance from engine operation. Furthermore, external factors such as thermal expansion and contraction of components due to temperature changes can easily cause the originally adjusted lens angle to shift, leading to unstable lighting performance. This can range from minor issues like blurred driver vision and impaired judgment of road conditions to serious problems like direct headlight beams hitting oncoming drivers, causing glare and significantly increasing the risk of traffic accidents.
[0004] Furthermore, in existing technologies, the smooth movement between the linked components of the headlight adjustment module is crucial for its normal operation. However, during long-term vehicle use, the gears and other transmission components inside the module are susceptible to corrosion from the external environment. On the one hand, the vehicle's driving environment is complex and diverse; dust, sand, and other impurities in the outside air can easily enter the transmission mechanism and adhere to the gear meshing surfaces, significantly increasing the resistance between gears. In severe cases, this can even cause gear jamming, affecting the normal operation of the adjustment function. On the other hand, in humid environments, such as rainy or snowy weather, or driving in high-humidity areas, moisture can easily penetrate the transmission components, causing corrosion of gears, racks, and other transmission parts. This not only reduces transmission efficiency but also shortens the service life of components, affecting the reliability of the entire module. Although existing technologies incorporate certain protective measures for gear transmissions, the protective effect still has significant drawbacks and is difficult to effectively resist the continuous impact of dust, moisture, and other factors.
[0005] Furthermore, to improve the protective performance of the transmission mechanism, existing modules typically use sealing rings for sealing protection to prevent the intrusion of external impurities and moisture. However, there is currently no effective means to monitor the condition of the sealing rings. Over long-term use, the sealing rings may experience a decline in sealing performance or even fail due to aging, wear, deformation, and other reasons. Once the sealing rings malfunction, external impurities and moisture can enter the transmission mechanism, exacerbating damage to transmission components. However, due to the lack of monitoring, drivers cannot be aware of the sealing ring failure in a timely manner, and repairs are often only carried out after obvious malfunctions occur in the module. This not only increases maintenance costs but may also lead to safety accidents during driving due to module failure.
[0006] In summary, the deficiencies of existing automotive lighting adjustment modules in terms of angle stability, transmission mechanism protection, and seal condition monitoring have become important factors restricting their performance improvement and ensuring driving safety, and urgently require improvement and optimization.
[0007] Therefore, this invention proposes an automotive headlight lens adjustment linkage module to solve the above problems. Summary of the Invention

[0023] Preferably, the arc-shaped cavity is filled with compressed gas.
[0024] Compared with existing technologies, this invention provides an automotive headlight lens adjustment linkage module with the following advantages: 1. Through the design of the connector and the connector hole, and with the assistance of the housing, this invention can bring the following advantages in the working environment of the headlight: Adapting to thermal expansion and contraction conditions and avoiding component damage: The design of the connector and the connector hole in the second component, combined with the assistance of the housing, can cleverly cope with the effects of thermal expansion and contraction. When temperature changes cause the component to expand and contract, even if the frustum in the second component drives the fan blade to move, it will only cause the insertion depth of the connector in the connector hole to change adaptively, rather than subjecting the component to rigid stress; the above-mentioned flexible adjustment method avoids the deformation, cracking and other damage problems caused by the obstruction of component expansion and contraction when the temperature changes drastically, and also prevents the malfunction of working components caused by stress concentration, significantly improving the structural tolerance of the adjustment module in complex temperature environments.
[0025] Ensuring continuous fixation and maintaining adjustment accuracy: During the movement of components caused by thermal expansion and contraction, the fit between the connector and the connector hole always maintains effective fixation of the first component (lens module adjustment component). Regardless of changes in insertion depth, the connection between the two remains uninterrupted, ensuring that the angle of the lens module adjustment component remains stable and will not unexpectedly shift due to temperature fluctuations. This guarantees the long-term accuracy of the headlight illumination angle and provides continuous and reliable protection for driving safety.
[0026] Simplified structural adaptability and reduced maintenance costs: Compared to traditional fixed devices that require complex compensation mechanisms to cope with thermal expansion and contraction, the design of the connectors and sockets can adapt to working conditions simply by adapting to changes in their own structure, without the need for additional adjustment components or complex control systems. This simplified structural design not only reduces the manufacturing cost of the module but also reduces the risk of failure due to improper coordination of multiple components. At the same time, due to the reduced component failure rate, the module's maintenance frequency is significantly reduced, indirectly lowering the vehicle's maintenance and operating costs.
[0027] 2. The addition of protrusions A and B in this invention brings the following beneficial effects: enhanced fixation reliability and better response to unexpected thermal expansion and contraction: When the degree of thermal expansion and contraction exceeds expectations, protrusions A and B on the ring in the second component and the arc-shaped component in the third component play a crucial role. This transforms the original single-mode fixation, which relied solely on the connector and insertion hole, into a dual-mode fixation where the connector and insertion hole are fixed together, and the arc-shaped component and ring are tightly fitted together by the protrusions, providing auxiliary fixation. Protrusions A and B allow the arc-shaped component and ring to fit tightly together, forming additional fixing force. This, combined with the cooperation of the connector and insertion hole, significantly improves the fixation strength of the first component (lens module adjustment component). Even if the insertion depth of the connector and insertion hole changes significantly due to extreme thermal expansion and contraction, the dual-mode fixation effectively counteracts these effects, improving stability, preventing lens angle deviation, and ensuring the stability of the fixation effect.
[0028] Reduced load on a single structure and extended component lifespan: In the dual-fixation mode, the fixing pressure borne by the connector and socket is partially shared by the auxiliary fixation formed by the arc-shaped component and ring through the protrusions. This means that in daily use and when dealing with unexpected thermal expansion and contraction, the load on the single fixing structure is reduced, minimizing wear and deformation problems caused by excessive stress on the connector and socket over a long period. At the same time, the force distribution between the protrusions and the ring and arc-shaped component is more uniform, avoiding localized stress concentration and extending the lifespan of the ring, arc-shaped component, and other related components, further improving the overall durability of the adjustment module.
[0029] 3. This invention, through the design of the arc block sliding within the arc cavity and the addition of a diaphragm, achieves the following beneficial effects: precise response to large vibrations and rapid switching of the fixing mode: The design of the arc block sliding within the arc cavity, combined with the addition of a diaphragm, constructs a triggering mechanism for large vibrations. When the vehicle experiences severe vibration, causing the indirectly fixed connector on the arc block to rigidly abut against the inner wall of the connector hole, and the spring A to be forced to deform and buffer, the resulting impact force will cause the diaphragm to rupture, releasing the compressed air within the arc cavity; this process can quickly trigger the arc component and the ring to abut against each other through the protrusions, realizing the switching from a single fixing mode to a dual fixing mode; compared to the drawback of traditional fixing devices that are difficult to adaptively adjust during vibration, this design can accurately capture the vibration intensity and complete the mode switching at critical moments, providing a more stable fixation for the lens module adjustment assembly.
[0030] In conjunction with the thermal expansion and contraction switching mode, this design covers stable requirements in multiple scenarios and environments: The vibration-triggered fixing mode switching achieved by this design complements the fixing mode change caused by thermal expansion and contraction. In high or low temperature environments, the depth changes of the connector and the connector hole, as well as the assisted fixing by the protrusions, cope with thermal expansion and contraction. In scenarios with large vibrations, such as rough roads and sudden braking, the mode switching is completed by the sliding of the arc block and the diaphragm rupture mechanism. The synergy of these two modes breaks the limitations of single-environment adaptability, enabling the automotive lighting adjustment module to maintain a stable fixing effect in various complex scenarios such as thermal expansion and contraction and severe vibration, greatly improving the environmental adaptability of the module.
[0031] 4. This invention, through the coordinated design of the second and third components, brings several significant benefits to the performance of the automotive headlight adjustment module, specifically as follows: Improved lens module angle stability: The coordinated design of the second and third components effectively restricts the first component, i.e., the lens module adjustment component, overcoming the lack of a limiting mechanism in existing technologies. When the vehicle encounters external factors such as vibration or temperature changes, this limiting effect firmly fixes the adjusted lens angle, preventing angle deviation and ensuring that the headlights are always in optimal illumination condition. This reduces blurred vision or glare for oncoming vehicles caused by angle changes, significantly improving driving safety.
[0032] The structural reliability and durability of the adjustment module have been improved: The above-mentioned design not only effectively limits the angle of the lens module, but also enhances the overall structural strength of the module to a certain extent. During long-term use, it can better resist the influence of external factors on the internal structure of the module, reduce the additional wear of components caused by problems such as angle deviation, extend the service life of the lens module adjustment components and related moving parts, reduce the frequency of module maintenance and replacement, and thus save on operating costs.
[0033] 5. The design of the fourth component in this invention brings the following beneficial effects: real-time monitoring of the sealing condition and early warning of sealing failure risk: The strain gauge design in the fourth component provides a precise numerical feedback channel for changes in the gas volume within the gas storage chamber (composed of a bladder cover and a mounting groove for the base component). Since the sealing performance of the gas storage chamber directly depends on the performance of the sealing component, when the sealing effect decreases due to aging, wear, or deformation of the sealing component, the gas volume within the storage chamber will change accordingly. The strain gauge can indirectly capture this situation by sensing changes in gas pressure. The aforementioned real-time monitoring mechanism overcomes the limitation of existing technologies that cannot effectively monitor the sealing condition, and can issue an early warning before the sealing component completely fails, giving users sufficient time for repair and replacement, and avoiding subsequent problems caused by sealing failure.
[0034] Indirect feedback on the risk of impurity intrusion ensures the normal operation of transmission components: The gas volume changes fed back by the strain gauge not only reflect the condition of the seals but also indirectly indicate whether there is a possibility of impurity intrusion in the area covered by the gas bladder, namely the location of the adjusting teeth, transmission teeth, and linkage rack. When the sealing effect of the seals deteriorates, external dust, sand, and other debris can easily enter the transmission area through gaps, causing gas in the gas storage chamber to flow with the outside and resulting in changes in gas volume. After the strain gauge detects this change, it can promptly provide feedback on the potential risk of impurity intrusion into the transmission components, thereby allowing for early cleaning or protective measures to be taken. This effectively prevents increased transmission resistance, jamming, or even seizure of components such as the transmission teeth and rack due to impurity accumulation, ensuring the smooth operation of the adjustment module's transmission adjustment function.

[0068] A further embodiment: Please refer to Figure 6 , Figures 8 to 11As shown: The third component 4 includes an arc-shaped part 401 fixedly connected to the fan blade 307. The outer arc surface of the arc-shaped part 401 is fixedly connected with protrusions A402 at equal intervals. An arc-shaped cavity 403 is opened inside the arc-shaped part 401.

[0070] Among them, the third component 4 is used to avoid interference from external temperature and vibration environment on the second component 3.
[0071] The arc-shaped cavity 403 is filled with compressed gas.
[0072] Diaphragm 405 can be implemented as a fluororubber (FKM) sheet.
[0073] Spring A407 is used for centering constraint of arc block 406.
[0074] Spring B408 is used to assist in the position movement and reset of connector 308.
[0075] The fourth component 5 is used to monitor the condition of the device seals and whether the gear adjustment module is affected by external impurities.
[0076] The strain gauge 503 is electrically connected to the main controller of the device, and its numerical feedback can indirectly reflect the change in the amount of gas in the gas storage chamber.
[0077] It should be noted that the second component 3 is the active fixation of the first component 2, and the third component 4 is the passive fixation of the first component 2.
[0078] The working principle of all the contents in the above embodiments is as follows: In the initial state: the gas storage chamber formed by the bladder cover 301 and the mounting groove of the base 1 is not filled with gas; the frustum 306 does not squeeze the fan blade 307; the connector 308 is not inserted into the connector hole 310; the protrusion A402 and the protrusion B409 are not in contact; the diaphragm 405 is not broken; the springs A407 and B408 are in a normal relaxed state; and the spring C501 is in a stretched state.
[0079] The following is the working process of the first component 2 and the second component 3: In use, the operator inserts a screwdriver into the cross groove of the adjusting tooth 201, and then uses the screwdriver to make the adjusting tooth 201 rotate. During this process, the adjusting tooth 201 will cause the linkage rack 203 to rotate through the transmission tooth 202. The rotation of the linkage rack 203 will cause the other end of the transmission tooth 202, which is engaged with it, to rotate together. Furthermore, in the rotation of the transmission tooth 202, the transmission tooth 202 will drive the screw 205 to rotate through the fixedly connected cross column cavity 204, thereby adaptively adjusting the angle of the lens module 207 with the assistance of the buckle 206.
[0080] Furthermore, after adjustment, the capsule cover 301 is placed on the base 1, and then the capsule cover 301 is fixed to the base 1 by fasteners 302. At this time, the capsule cover 301 and the mounting groove on the base 1 form a gas storage chamber. Further, air is pumped into the gas storage chamber through the inflation valve on the capsule cover 301. During this process, the capsule cover 301 will move with the pull rod 305 through the transverse member 304. As the pull rod 305 moves, the truncated cone 306 on the pull rod 305 will gradually approach and push the fan blade 307. As the fan blade 307 expands outward, the plug-in member 308 connected in the middle of the arc member 401 on the fan blade 307 will gradually move towards the plug-in hole 310 opened on the ring 309, and finally plug into the plug-in hole 310. Thus, the limiting operation of the angle adjustment of the complete lens module 207 is completed.
[0081] Furthermore, when the gas in the gas storage chamber formed by the bladder cover 301 and the mounting groove on the base 1 is affected by the temperature brought about by the operation of the vehicle lights, the pull rod 305 will move a certain distance. At this time, the above process will occur again, and the insertion part 308 will be inserted into the insertion hole 310 a deeper distance.
[0082] It should be noted that the gas expansion caused by high temperature will result in two situations: first, the insertion depth of the connector 308 in the connector hole 310 will increase; second, the arc-shaped part 401 will have its protrusion A402 in close contact with the protrusion B409 on the inner wall of the ring 309.
[0083] Please refer to the above work process. Figures 1 to 9 .
[0084] The following is the working process of the third component 4: Furthermore, if the vehicle experiences significant vibration while driving, the connector 308 on the arc block 406 will move relative to the position of the connector 310 on the ring 309 during the vibration. That is, under significant vibration, the connector 308 will cause the arc block 406 to slide in the arc cavity 403 under the constraint of the connector 310. At this time, the spring A407 is no longer in its normal relaxed state. At this time, the arc block 406 will perform a vibration buffering action with the assistance of the compressed gas in the arc cavity 403; or if the vibration is too large... The arc block 406 will force the diaphragm 405 to rupture during the compression of air. At this time, the compressed gas will enter the gas storage chamber composed of the capsule cover 301 and the mounting groove on the base 1. As the gas increases, the pull rod 305 will indirectly cause the arc-shaped part 401 to move closer to the ring 309 through the movement of the frustum 306 during the expansion of the capsule cover 301. At this time, under the action of the protrusion A402 on the arc-shaped part 401 and the protrusion B409 on the inner ring wall of the ring 309, a large friction force can be provided during vibration, thereby offsetting the effect of vibration on fixation.
[0085] It should be noted that, under conditions of both high temperature and high vibration, the second component 3 and the third component 4 will work together.
[0086] Please refer to the above work process. Figures 8 to 11 .
[0087] The following is the working process of the fourth component 5: On the other hand, if the seals in the device experience lifespan issues under high temperature or other environmental conditions, leading to abnormal sealing performance, as the amount of gas in the gas storage chamber decreases, the strain gauge 503, which originally provided feedback data value A, will now provide feedback value B, where A < B. Since it is known that there is an electrical connection between the strain gauge 503 and the device's main controller, its numerical feedback can indirectly reflect the change in the amount of gas in the gas storage chamber. Therefore, relevant personnel can use the numerical feedback to know that there is a problem with the device's seals and that they need to be replaced in time, thereby avoiding sealing problems. The transmission components such as the adjusting gear 201, transmission gear 202, and linkage rack 203 may have their transmission efficiency affected by dust and other impurities.
