Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle lamp adjustment, and in particular relates to a dimming fulcrum structure. Background Art

[0002] The main function of automobile headlights is lighting. They must illuminate the road ahead without dazzling the oncoming vehicles. They are key components to ensure the drivability and safety of the automobile. However, in actual driving, when the load of the automobile or the road slope changes, the inclination angle of the vehicle body relative to the road surface often changes greatly, which will cause the lighting distance and lighting direction of the low beam to change, thus affecting its function and driving safety.

[0003] In order to ensure driving safety under different conditions, the headlights need to be equipped with a dimming mechanism to adapt to different environments. Generally, the dimming mechanism has a fulcrum on one side of the dimming bracket and an adjustment structure on the other side. The transmission mechanism is used to adjust the bracket angle to change, thereby achieving headlight angle adjustment.

[0004] At present, in the existing dimming mechanisms, the dimming fulcrum is achieved by the cooperation of a ball screw, a bushing and a ball sleeve on the dimming bracket, so that the relative position between the two remains unchanged and only the angle rotates. The dimming fulcrum needs to be realized with the help of a ball screw and a ball sleeve, which is relatively expensive, and the structure is not firm. When the lamp is vibrated, the ball head is easy to disengage, thereby causing the dimming system to fail. Utility Model Content

[0007] Preferably, the dimming components are provided in two groups, and the straight line where the fulcrum component and one group of dimming components are located is perpendicular to the straight line where the fulcrum component and the other group of dimming components are located.

[0008] Preferably, the transmission rod can drive the lifter to move along the axial direction of the transmission rod.

[0009] Preferably, the shell is provided with a slideway matching with the lifter.

[0012] After adopting the above technical solution, the dimming fulcrum structure provided by the utility model has the following beneficial effects:

[0021] The present invention is further described clearly and completely below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0023] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps described in these embodiments do not limit the scope of the utility model. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0024] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0025] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0026] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0027] The utility model provides a dimming fulcrum structure, such as Figure 1-6 As shown, it includes a dimming bracket 1, a shell 2, and a dimming component and a fulcrum component connected between the dimming bracket 1 and the shell 2. The dimming bracket 1 can rotate relative to the shell 2 with the fulcrum component as a rotating fulcrum under the drive of the dimming component.

[0028] The dimming components are provided in two groups, and the straight line where the fulcrum component and one group of dimming components are located is perpendicular to the straight line where the fulcrum component and another group of dimming components are located, thereby realizing the adjustment of the dimming system in two directions.

[0029] The dimming component includes a transmission rod 4 and a lifter 5 connected to the transmission rod 4. The end of the lifter 5 is provided with a ball head that cooperates with the ball cap 1-1 on the dimming bracket 1. Specifically, one end of the transmission rod 4 is connected to the shell 2, and the other end is connected to the lifter 5. The axial movement of the transmission rod 4 can drive the lifter 5 to move in the same direction. At the same time, in order to ensure stability in the direction of movement, a slideway that cooperates with the lifter 5 is provided on the shell 2. The end of the lifter 5 away from the transmission rod 4 is provided with a ball head. The ball head is rotatably matched with the ball cap 1-1 through the bushing 3, so that the axial movement of the transmission rod 4 can be transmitted to the dimming bracket 1 to cause an angle change.

[0030] The fulcrum assembly includes a spherical fulcrum 1-2 arranged on the dimming bracket 1, and a support seat 2-1 that cooperates with the spherical fulcrum 1-2 is provided on the shell 2. Specifically, a cover plate 6 is also provided on the side of the spherical fulcrum 1-2 away from the support seat 2-1. The cover plate 6 is installed on the support seat 2-1 by screws 7, and an adjustment space is formed between the cover plate 6 and the support seat 2-1 for the spherical fulcrum 1-2 to cooperate with the dimming assembly to rotate. Such a design can be more reliable than the clamping fixation of the bushing and the ball head in the prior art, and is not easily disengaged due to the vibration of the vehicle bumps, thereby ensuring the stability of the dimming system; further, the dimming angle change is achieved by integrating the spherical fulcrum 1-2 on the dimming bracket, which can reduce the cost of the dimming system.

[0031] When the dimming fulcrum structure of the utility model is in use, because a group of dimming components are respectively arranged at the upper right corner and the lower left corner, and the fulcrum component is arranged at the lower right corner, if the light output angle needs to be adjusted in the up and down directions, the dimming component at the lower left corner can be kept stationary, and the transmission rod of the dimming component at the upper right corner can be rotated to move it in the direction close to the dimming bracket, so that the light output direction is deviated downward to the road surface, or the transmission rod is moved in the direction away from the dimming bracket, so that the light output direction is offset above the road surface; and if the light output angle needs to be adjusted in the left and right directions, the dimming component at the upper right corner can be kept stationary, and the transmission rod of the dimming component at the lower left corner can be rotated to move it in the direction close to the dimming bracket, so that the light output direction is offset to the right, or the transmission rod is moved in the direction away from the dimming bracket, so that the light output direction is offset to the left, so that the light output angle finally meets the requirement.

[0032] In summary, the dimming fulcrum structure provided by the utility model has the advantages of simple structure, can improve the stability of the dimming system, and can reduce the cost of the dimming system. It has great market value and deserves to be widely promoted and applied.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
