Description

Technical Field

[0001] The utility model relates to the technical field of automobile structures, and more specifically, to an anti-seismic structure of an automobile lamp. In addition, the utility model also relates to an automobile front lamp comprising the anti-seismic structure of the automobile lamp. Background Art

[0002] In recent years, the automobile industry has developed rapidly, and automobile lamps have evolved from the earliest halogen lamps to the current LED and laser lamps. The value of lamp products is also getting higher and higher. In the early days, headlights only had manual dimming requirements. When designing the dimming of lamps, up to 4 mechanical dimming structures could be designed, and the lamp reflector (or lens assembly) had good stability. Later, due to GB 4785-2016 requiring the headlights to add electric dimming requirements, so that the driver can adjust the light height up and down while sitting in the car, that is, it is necessary to add a dimming motor inside the lamp to realize the dimming function. At this time, it is necessary to change some manual dimming structures to motor dimming. The usual practice is to change the mechanical dimming structure at the bottom to motor control to realize the up and down electric dimming functions.

[0003] There are two common ways to increase the stability of the dimming structure of lamps, as follows:

[0004] The first is to increase the diameter of the screw rod by thickening it, that is, to increase the strength of the screw rod;

[0005] The second method is to replace the sliding nut with a slider slot structure. The slider is fixed on the lamp housing, which is equivalent to shortening the cantilever length of the screw rod and increasing the supporting force of the adjusting screw rod.

[0006] However, both of the above two methods have certain problems:

[0007] The first type is that after the diameter of the adjusting screw is thickened, all parts that match the screw need to be newly developed or adjusted in size, that is, the adjusting screw, elastic retaining ring, sliding nut, and sealing ring need to be newly developed. At the same time, the diameter of the lens connected to the sliding nut also needs to adjust the size of the mounting hole. There are many newly developed parts, the cycle is long, and the cost is relatively high, which is not conducive to platform development. There is also an upper limit to the range of screw thickening. Although the seismic performance is improved, the effect is limited;

[0008] The second method is suitable for newly developed products because the slide groove is designed on the lamp housing, while the lamp housing mold needs to be modified for mass-produced products. In addition, the strength and stability of the slider itself must be taken into consideration. There are requirements for the width of the slider. The wider the slider, the greater the resistance to screw adjustment, and the slider and the slide groove must have an interference fit (otherwise there will be shaking). This will increase the adjustment torque of the screw and affect the manual dimming experience. At the same time, the slider and the parts that have a matching relationship with the slider need to be newly developed. In addition, the slider is larger in size than the sliding nut and occupies a larger internal space. The internal space of the lamp is limited, and the layout requirements are high, which may sacrifice the dimming stroke.

[0009] In summary, how to improve the anti-vibration effect of the lens assembly without increasing the adjustment torque is a problem that needs to be urgently solved by those skilled in the art. Utility Model Content

[0036] The core of the utility model is to provide an anti-seismic structure for an automobile lamp, which can improve the anti-seismic effect of a lens assembly without increasing the adjustment torque.

[0037] Another core of the utility model is to provide a front vehicle lamp including the above-mentioned anti-vibration structure of the vehicle lamp.

[0038] It should be noted that the directions or positional relationships indicated by “upper”, “lower”, “front”, “back”, etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present application.

[0039] The present application provides an anti-seismic structure for an automobile lamp, comprising: a shock absorbing plate 1, a mechanical dimming knob 2, and a connecting piece 4;

[0040] The damping plate 1 is a plate-shaped structure, and is used to be fixed to the lamp housing;

[0041] The mechanical dimming knob 2 is used to penetrate the lens assembly 3, and one end of the mechanical dimming knob 2 that penetrates the lens assembly 3 is connected to the damping plate 1;

[0042] The connecting member 4 is detachably connected to the shock absorbing plate 1 and is used to fix the shock absorbing plate 1 to the lamp housing.

[0043] For details, please refer to the attached Figure 2 With attached Figure 3 The upper end of the shock-absorbing plate 1 is fixed to the lamp housing through a connecting piece 4, the mechanical dimming knob 2 is inserted into the rotating groove set on the lamp housing, and the other end of the mechanical dimming knob 2 passes through the lens assembly 3, and the end is fixedly connected to the shock-absorbing plate 1, so that both ends of the mechanical dimming knob 2 remain stable, and the seismic resistance can be improved without changing the torque. Compared with the existing technology, the structure is relatively simple, the newly developed parts are less, and the cost of product development (or improvement) is low. It is suitable for both newly developed lamps and for improving the seismic performance of mass-produced lamps.

[0044] Optionally, the shock absorbing plate 1 may be a plastic part or a sheet metal part, which needs to have a certain strength to be able to resist shocks.

[0045] Based on the above embodiments, the mechanical dimming knob 2 includes a knob 2-1, a sealing ring 2-2, an elastic member 2-3, a sliding nut 2-4, an adjusting screw 2-5 and a limit member 2-6. The knob 2-1 is arranged at the first end of the adjusting screw 2-5, the limit member 2-6 is sleeved on the second end of the adjusting screw 2-5, the sealing ring 2-2, the elastic member 2-3 and the sliding nut 2-4 are arranged between the knob 2-1 and the limit member 2-6, and the sliding nut 2-4 is used to clamp with the lens assembly 3.

[0046] For details, please refer to the attached Figure 1 With attached Figure 4 The knob 2-1, the adjusting screw 2-5 and the limiter 2-6 are fixedly connected, the elastic member 2-3 and the sealing ring 2-2 are fixed to the outer periphery of the adjusting screw 2-5, the sliding nut 2-4 is a fork-shaped structure, and a protrusion is arranged on the outer side, which can realize the clamping fixation with the lens assembly 3. When the adjusting screw 2-5 is rotated clockwise, the sliding nut 2-4 moves to the right under the action of the knob force, and when the knob 2-1 is rotated counterclockwise, the movement direction of the sliding nut 2-4 is opposite. Since the sliding nut 2-4 is fixed on the lens module 3, it drives the lower part of the lens assembly 3 to move to the left or right. At this time, the mechanical dimming on the upper side does not move, and the lens angle rotates clockwise or counterclockwise, thereby realizing the adjustment of the lighting distance.

[0047] On the basis of the above-mentioned embodiment, a shock-absorbing pad 5 is provided between the shock-absorbing plate 1 and the adjusting screw rod 2 - 5 , and the shock-absorbing pad 5 is used to reduce friction and noise.

[0048] Specifically, considering that the damping plate 1 is sleeved on the adjusting screw 2-5 and the adjusting screw 2-5 is a moving part, in order to eliminate dry friction and noise, a damping pad 5 is arranged between the damping plate 1 and the adjusting screw 2-5.

[0049] Optionally, the shock-absorbing pad 5 may be made of a rubber component, which has a low cost and a good shock-absorbing effect.

[0050] In some embodiments, the connecting member 4 is a screw, two connecting members 4 are provided, four through holes are provided on the shock absorbing plate 1, and the two through holes at the upper end of the shock absorbing plate 1 are used to correspond to the threaded holes on the lamp housing.

[0051] Specifically, the connecting member 4 is preferably a screw, and the detachable connection between the shock-absorbing plate 1 and the lamp housing is achieved through the threaded connection of the two screws. The cost of the screws is low and it is easy to improve the existing structure (add threaded holes), that is, there is no need to scrap the manufactured lamp housing, and it can still be improved and utilized, thereby reducing production costs.

[0052] Based on the above embodiment, the through hole at the lower end of the shock absorbing plate 1 is used for fixed connection with the limiting member 2-6. The limiting member 2-6 is a truncated cone structure with an annular groove on the side. An annular protrusion is provided in the through hole at the lower end of the shock absorbing plate 1.

[0053] Specifically, the shock-absorbing plate 1 is a plate-like structure that is approximately square, with two through holes respectively arranged at the upper and lower ends. The two through holes at the upper end are used to realize the fixed connection between the shock-absorbing plate 1 and the lamp housing, and the two through holes at the lower end correspond to the through holes arranged on the lens assembly 3. The annular groove arranged on the side of the limit member 2-6 corresponds to the annular protrusion in the through hole at the lower end of the shock-absorbing plate 1, and the size of the end of the limit member 2-6 away from the knob 2-1 is smaller than the size of the other end, and the limit member 2-6 is preferably a component with a certain elasticity so that the limit member 2-6 can be inserted into the through hole at the lower end of the shock-absorbing plate 1.

[0054] Optionally, the limiting member 2-6 may be composed of two detachably connected stepped frustums to facilitate installation.

[0055] Optionally, the limiting member 2 - 6 can be configured to be detachably connected to the adjusting screw rod 2 - 5 , and only needs to be configured as a columnar structure with a size larger than the through hole on the shock absorbing plate 1 .

[0056] Based on the above embodiment, the upper end of the shock absorbing plate 1 is an inclined end face, and a plurality of evenly distributed positioning protrusions are provided on the upper end of the shock absorbing plate 1, and two U-shaped protrusions are provided on the lower end of the shock absorbing plate 1, and through holes are provided on both U-shaped protrusions.

[0057] Specifically, the structure of the shock absorbing plate 1 is set according to the interior of the lamp housing, and attention should be paid to the front and back sides of the shock absorbing plate 1 during installation to ensure correct installation.

[0058] For the anti-seismic structure of the automobile lamp of the present application, the installation process is: 1. First install the adjusting screw 2-5 on the lamp housing; 2.

[0060] Specifically, the inner circumference of the sliding nut 2-4 is provided with threads, and the outer circumference of the adjusting screw 2-5 is provided with threads, so that the sliding nut 2-4 and the adjusting screw 2-5 are threadedly connected. Since the sliding nut 2-4 is fixedly connected to the lens assembly 3, the sliding nut 2-4 can slide on the adjusting screw 2-5 during the rotation of the adjusting screw 2-5. The position setting of the limiter 2-6 needs to ensure that the distance between the limiter 2-6 and the sliding nut 2-4 is greater than the dimming design stroke, that is, before the limiter 2-6 is added, the sliding nut 2-4 is rotated counterclockwise and moves forward until it is unscrewed. After the limiter 2-6 is added, when the sliding nut 2-4 contacts the limiter 2-6, the knob torque will increase significantly, and at this time, it can be used to remind the dimming personnel that the adjustment has been made.

[0061] In some embodiments, the diameter of the adjusting screw 2 - 5 is the same as the diameter of the through hole on the shock absorbing plate 1 .

[0062] Specifically, the adjusting screw 2-5 and the shock absorbing plate 1 are designed to be in a tight fit, so that the shock absorbing plate has a better shock absorbing effect and can offset the vibration factors during the rotation of the adjusting screw 2-5.

[0063] Optionally, the diameter of the adjusting screw rod 2-5 may be slightly smaller than the shock absorbing plate 1 to facilitate installation.

[0064] On the basis of the above-mentioned embodiment, a lubricating layer is provided between the adjusting screw rod 2 - 5 and the through hole on the damping plate 1 .

[0065] Specifically, during the installation of the adjusting screw 2-5, a lubricating layer should be provided on the adjusting screw 2-5. The lubricating layer is preferably grease, which can effectively reduce the rotational resistance of the adjusting screw 2-5 during rotation.

[0066] Optionally, lubricating oil may be used as the lubricating layer, and a lubricating oil supply device may also be provided to maintain the lubricity of the surface of the adjusting screw 2-5.
