Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp structures, in particular to a suspension anti-adjustment structure for a reflector inside a vehicle lamp. Background Art

[0002] The headlights installed on the front of the car cannot ensure that their lights can shine on the road surface required by the design due to the deviation of their body mounting structure. This requires the lighting system (reflector) inside the headlight to be adjusted so that its light can shine on the road surface required by the design. When adjusting the lighting system (reflector), since the debugging personnel do not understand the internal structure of the lamp, when rotating the adjustment screw forward or backward, it is easy to adjust the ball head slider that suspends the lighting system (reflector) off, that is, the ball head slider is adjusted off the original track, causing it to lose its adjustment function, making the lamp unable to work normally. When resetting, it is necessary to remove and open the front cover in front to install the internal ball head slider. Therefore, a limiting structure that limits the adjustment of the ball head slider is needed to limit the movement distance of the ball head slider. Utility Model Content

[0003] Based on the above description, the utility model provides an anti-drop-adjustment structure for the suspension of the internal reflector of a vehicle lamp to solve the problem in the prior art that the displacement distance of the ball head slider is not limited and is prone to drop-off.

[0004] The technical solution of the utility model to solve the above technical problems is as follows:

[0005] A structure for preventing a reflector from being dislodged and suspended inside a vehicle lamp, comprising:

[0006] Seat plate;

[0007] A slide rail, vertically arranged on the seat plate;

[0008] A ball head slider, slidably connected in the slide rail;

[0009] A sleeve connected to the side of the ball head slider;

[0010] An adjusting bolt is arranged on the seat plate and is threadedly sleeved with the sleeve;

[0011] A limit plate is arranged on the seat plate to limit the sleeve or the ball head slider from being away from the seat plate.

[0012] On the basis of the above technical solution, the present invention can also be improved as follows.

[0013] Furthermore, a circular hole is formed on the limiting plate, and the diameter of the circular hole is larger than the threaded end of the adjusting bolt and smaller than the sleeve.

[0014] Furthermore, extension plates are connected to both sides of the limit plate, and the ends of the extension plates are connected to the bottom plate. The limit plate, the extension plate and the bottom plate together form a "X"-shaped structure, and the bottom plate and the seat plate are fixed with screws.

[0015] Furthermore, a first threaded seat is provided on the seat plate, and the base plate is placed on the first threaded seat and is threadedly connected to the first threaded seat using screws.

[0016] Furthermore, the limit plate cover is arranged at the end of the slide rail to prevent the ball head slider from sliding out of the slide rail.

[0017] Furthermore, a second threaded seat is provided on the side edge of the end of the slide rail, a hole corresponding to the second threaded seat is opened on the limiting plate, and a protrusion is connected to the limiting plate. When the limiting plate is attached to the end face of the slide rail, the protrusion is clamped with the end face of the slide rail away from the second threaded seat.

[0018] Furthermore, the ball head sliders are provided in three groups and are connected to the cylinder in a circumferentially distributed manner with the sleeve, and the slide rails are provided in three groups corresponding to the ball head sliders.

[0019] Furthermore, the limiting plate is arranged on the slide rail close to the sleeve.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0021] This solution blocks the displacement of the sleeve or the ball head slider by installing a limit plate on the sleeve or the slide rail. Relying on the synchronous movement of the sleeve and the ball head slider, the entire synchronous motion structure can be limited and blocked to prevent it from sliding out of the slide rail due to excessive adjustment, avoiding the need to disassemble the headlight panel for reinstallation. The overall structure is simple and easy to manufacture and install. It solves key problems with a small structure and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0029] It will be appreciated that spatial relationship terms such as "under," "beneath," "below," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be appreciated that, in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "above" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0030] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediate element. The "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc. if the connected circuits, modules, units, etc. have electrical signals or data transmission between each other.

[0031] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0032] like Figure 1-3 The structure for preventing the suspension of the reflector inside the headlight from being disengaged is shown, and includes a seat plate 1 arranged in the headlight module, and a slide rail 2 is connected inside the seat plate 1, and the slide rail 2 is vertically arranged on the seat plate 1, that is, its extension direction is perpendicular to the seat plate 1. A ball head slider 3 is slidably connected inside the slide rail 2, and a sleeve 4 is connected to the side of the ball head slider 3, and the sleeve 4 has a thread inside, and an adjusting bolt 5 is rotatably connected to the seat plate 1, and the adjusting bolt 5 is clamped on the seat plate 1 through a locking gasket 13, and the adjusting bolt 5 passes through the seat plate 1, and its threaded end is perpendicular to the seat plate 1 and parallel to the sleeve 4, and the sleeve 4 is threadedly sleeved on the adjusting bolt 5, and by rotating the adjusting bolt 5 at the outer end of the seat plate 1, the sleeve 4 and the ball head slider 3 are driven to move closer to or farther from the seat plate 1, and a ball head is connected to the end of the ball head slider 3, and the ball head slider 3 pushes the ball head, and the ball head drives the lamp in front to deflect, thereby achieving the purpose of adjusting the light angle. In order to prevent the operator from inexperiencedly turning the adjusting bolt 5 too many times and causing the ball head slider 3 to be adjusted away from the slide rail 2, the present solution is designed with a limit plate 6 arranged on the seat plate 1, which is used to limit the sleeve 4 or the ball head slider 3 and prevent it from being too far away from the seat plate 1.

[0033] In one embodiment, Figure 1 As shown, a circular hole is provided on the limit plate 6, and the diameter of the circular hole is larger than the threaded end of the adjusting bolt 5 and smaller than the sleeve 4. The limit plate 6 limits the displacement of the sleeve 4 by being sleeved on the threaded end of the adjusting bolt 5. Specifically, the two sides of the limit plate 6 are connected with extension plates 7, and the ends of the extension plates 7 are connected with the bottom plate 8. The limit plate 6, the extension plate 7 and the bottom plate 8 together form a "X"-shaped structure, and the bottom plate 8 is fixed to the seat plate 1 with screws. Since the seat plate 1 is relatively thin, the present solution provides a first threaded seat 9 on the seat plate 1, and the first threaded seat 9 is provided on the side with the slide rail 2. The bottom plate 8 is placed on the first threaded seat 9 and is threadedly connected to the first threaded seat 9 with screws. When initially installing the lamp assembly, the limit plate 6 structure is installed on the first threaded seat 9 to ensure that there will be no adjustment problems in subsequent maintenance operations. The first threaded seat 9 is arranged on the side of the seat plate 1 facing the slide rail 2. Even the extension of the first threaded seat 9 is also arranged on the back side of the seat plate 1. Since the space on the back side of the seat plate 1 is limited and the depth of the back side is also limited, this design increases the upper limit of the length of the fixing bolt.

[0034] In another embodiment, Figure 3As shown, the limit plate 6 is covered at the end of the slide rail 2 to prevent the ball head slider 3 from sliding out of the slide rail 2. Specifically, a second threaded seat 10 is provided on the side of the end of the slide rail 2, and a hole corresponding to the second threaded seat 10 is opened on the limit plate 6, and the limit plate 6 is fixed to the end of the slide rail 2 by bolts. The reason why the slide rail 2 is not sealed at the end is so that the ball head slider 3 can be directly inserted into it during the initial installation. If it is fixed only by bolts, the limit plate 6 will rotate around the bolts under the influence of vibration caused by long-term use of the vehicle, and this structure is not a problem. Preferably, a convex point 11 is integrally connected to the limit plate 6. When the limit plate 6 is attached to the end face of the slide rail 2, the convex point 11 is clamped with the end face of the slide rail 2 away from the second threaded seat 10. The convex point 11 and the bolt work together to stably clamp at the end of the slide rail 2, and this structure is easy to install and disassemble.

[0035] In one embodiment, three groups of ball head sliders 3 are provided, and are connected to the cylinder 12 in a circumferentially distributed manner with the sleeve 4, and the slide rail 2 is also provided with three groups corresponding to the ball head sliders 3. The limit plate 6 is provided on the slide rail 2 close to the sleeve 4, and two groups can be provided, which are respectively located on both sides of the sleeve 4.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
