[0027] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0028] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operate in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0029] See also Figure 1-3 As shown, this embodiment provides a small lamp test fixture, which is mainly used to fix the license plate lamp when testing the license plate lamp of the car. It mainly includes a base frame 1, a reference plate, a mounting seat 4, an angle adjustment bracket, a vertical adjustment bracket, and a horizontal adjustment bracket, etc., which are specifically described below:

[0030] like Figure 1 As shown, the reference plate 2 is used to provide a horizontally set reference surface. For example, in this embodiment, the reference plate 2 is a horizontally set flat plate structure, and its top surface is used as a reference surface. A license plate plate 21 for simulating a license plate is installed on the reference plate 2, and the license plate 21 is vertically perpendicular to the reference surface.

[0031] The vertical adjustment bracket is used to vertically adjust the vertical distance of the lamp relative to the reference surface and can indicate the vertical distance. Its specific structure is as follows:

[0032] like Figure 1As shown, the vertical adjustment bracket includes a first guide rail 61 extending vertically, a slider 62 slidably arranged on the first guide rail 61 and capable of vertically sliding along the first guide rail 61, and a first locking member for locking the slider 62; the first guide rail 61 is fixed to the base frame 1; the outer wall of the first guide rail 61 is provided with third scale lines 63 distributed in sequence along the vertical direction, and the third scale lines 63 are mainly used to indicate the vertical distance. The reference plate 2 is fixed to the first guide rail 61.

[0033] The first locking member can be a first bolt (not shown in the figure), which is threadedly connected to the slider 62. When locking the slider 62, the first bolt is tightened so that the inner end of the first bolt is pressed against the outer wall of the first guide rail 61 to lock the slider 62. Conversely, when the slider 62 needs to be slid, the first bolt can be loosened.

[0034] In addition, in order to prevent the slider 62 from rotating circumferentially around the first guide rail 61, in this embodiment, the first guide rail 61 can be designed as a polygonal column structure; of course, the first guide rail 61 can also be a cylindrical structure. In this case, a convex key and a keyway need to be provided between the slider 62 and the cylinder to form a key matching structure. For example, the convex key is provided on the outer peripheral wall of the first guide rail 61 and extends vertically along the first guide rail 61; the keyway is provided on the slider 62; the circumferential rotation of the slider 62 relative to the first guide rail 61 is limited by the key matching structure.

[0035] The lateral adjustment bracket is used to laterally adjust the lateral distance of the lamp relative to the license plate 21 and can indicate the lateral distance, specifically:

[0036] The lateral adjustment bracket includes a second guide rail 71 and a second locking member, wherein the second guide rail 71 extends in the lateral direction and is slidably arranged on the slider 62 in the lateral direction so that it can slide in the lateral direction relative to the slider 62; the outer wall of the second guide rail 71 is provided with second scale lines 72 distributed in sequence in the lateral direction, and the second scale lines 72 are used to indicate the lateral distance.

[0037] The second locking member is used to lock the second guide rail 71; the second locking member can be a second bolt (not shown in the figure), which is threadedly connected to the slider 62. Its locking principle is the same as that of the first bolt, and can be referred to as the first bolt, so no further details are given here.

[0038] Similarly, in order to prevent the second guide rail 71 from rotating circumferentially relative to the slider 62, the shape of the second guide rail 71 can be designed like the shape of the first guide rail 61. For example, the second guide rail 71 can be designed as a polygonal column structure, or designed as a cylindrical structure and provided with a key fitting structure similar to the aforementioned one.

[0039] The angle adjustment bracket is connected to the mounting seat 4 for adjusting the angle of the lamp and can indicate the current angle of the lamp, wherein the mounting seat 4 is provided with a clamp 3 for clamping the lamp.

[0040] Combination Figure 2 As shown, the angle adjustment bracket includes a hinge seat 51 , and the hinge seat 51 is fixed to one end of the second guide rail 71 .

[0041] The mounting seat 4 is rotatably connected to the hinge seat 51 around the first axis; wherein, there is a damping force at the rotational connection between the hinge seat 51 and the mounting seat 4, and the mounting seat 4 can maintain the current angle under the action of the damping force, that is, there is a self-locking effect between the hinge seat 51 and the mounting seat 4. When no external force is applied to the mounting seat 4, under the action of the damping force, the mounting seat 4 maintains the current angle relative to the hinge seat 51. When the angle needs to be adjusted, it is only necessary to apply force to overcome the damping force to drive the mounting seat 4 to rotate.

[0042] The above damping force is specifically formed as follows:

[0043] like Figure 2 As shown, the hinged seat 51 includes two ear plates 511 that are relatively spaced apart, and the mounting seat 4 includes a hinged end, which is rotatably connected between the two ear plates 511 and is interference fit with the two ear plates 511 to form the damping force, that is, the hinged end is squeezed between the inner walls of the two ear plates 511, and the damping force is formed by the friction between the hinged end and the inner walls of the ear plates 511.

[0044] The specific structure of the hinged end is as follows: the hinged end includes a damping part and a rotating shaft 52; the damping part is fixedly connected to the mounting seat 4, and the damping part is interference fit between the two ear plates 511; the rotating shaft 52 is rotatably connected to the ear plates 511, and at this time, the central axis of the rotating shaft 52 constitutes a first axis, so that the damping part and the mounting seat 4 as a whole can rotate circumferentially around the first axis to achieve angle adjustment.

[0045] In addition, in order to increase the damping force generated by the damping part, in this embodiment, Figure 2 As shown, the damping part is a sphere 41, and arc-shaped grooves 512 are provided on the side walls of the two ear plates 511 on opposite sides. The sphere 41 is interference-fitted in the grooves 512 on both sides. The spherical damping part cooperates with the grooves 512, which can increase the contact surface between the damping part and the ear plate 511, thereby increasing the friction force and improving the damping force.

[0046] In addition, in order to indicate the current angle of the mounting base 4 in real time, in this embodiment, Figure 1As shown, the mounting base 4 is provided with a wheel 53 which rotates synchronously with the mounting base 4 around the first axis. Specifically, one end of the rotating shaft 52 extends out of the outer side of the ear plate 511 and is fixed to the wheel 53, and the other end is fixedly connected to the damping part; the wheel 53 is provided with an indication mark 531. For example, a convex ridge can be set on the outer peripheral wall of the wheel 53 as the indication mark 531. Of course, other types of indication marks 531 can also be used, which are not specifically limited here.

[0047] Correspondingly, a circle of first scale lines 54 for indicating angles is provided on the articulated seat 51 at a position corresponding to the wheel disc 53 and surrounding the first axis. The first scale lines 54 are mainly used to indicate angles.

[0048] Since the mounting seat 4 and the wheel disc 53 are relatively fixed, the rotation angle of the mounting seat 4 is equivalent to the rotation angle of the wheel disc 53 .

[0049] In this embodiment, two clamps 3 are preferably provided, and the two clamps 3 are used to clamp the two sides of the lamp respectively. The clamp 3 can be some existing mechanical clamps 3, such as a clamp-type clamp 3, which mainly includes two clamp arms 31 arranged opposite to each other and capable of relatively rotating, and a torsion spring (not shown in the figure) is provided between the two clamp arms 31. The torsion spring provides a torsion force to keep the clamping ends of the two clamp arms 31 close to each other, so that the lamp is clamped between the two clamp arms 31. The distance between the two clamps is greater than the width of the license plate 21.

[0050] As a testing method of this embodiment, the following steps are included:

[0051] The first step is to adjust the lamp to the three setting parameter positions required for the test. The three parameters are the angle A of the lamp relative to the horizontal plane, the vertical distance L1 between the lamp and the reference plane of the reference plate 2 when the lamp is at angle A, and the horizontal distance L2 between the lamp and the license plate 21 when the lamp is at angle A. The specific adjustment steps are:

[0052] First, use the fixture 3 to place the lamp to be tested (such as Figure 3 The lamp is clamped on the mounting base 4 (as shown in the middle M part), and then the mounting base is rotated to adjust the angle of the lamp to a predetermined angle A (the angle A here can be read from the first scale 54), and maintained at the angle A.

[0053] Next, perform a zero adjustment operation, which specifically includes the following steps:

[0054] First, move the second guide rail 71 laterally until the end of the lamp touches the license plate, stop moving the second guide rail 71, and record the scale value corresponding to the current second scale line 72 through the second scale line 72, and record it as the zero point of the second scale line 72.

[0055] Next, the vertically moving slider 62 drives the second guide rail 71, the lamp, etc. to move vertically as a whole until the lower part of the lamp touches the reference surface of the reference plate 2, and stops moving the slider 62; and the scale value corresponding to the current third scale line 63 is recorded through the third scale line 63, and it is recorded as the zero point of the third scale line 63.

[0056] After completing the above zeroing action, the second guide rail 71 is moved laterally for a distance, the length of which is equal to the value of the aforementioned predetermined lateral distance L2. At this time, the distance between the lamp and the license plate is the aforementioned lateral distance L2.

[0057] Then the slider 62 is moved vertically for a distance, the length of which is equal to the value of the aforementioned predetermined vertical distance L1. At this time, the distance between the lamp and the reference surface is recorded as the aforementioned vertical distance L1.

[0058] At this point, the position adjustment of the lamp relative to the license plate is completed.

[0059] In the second step, the brightness meter device is fixed, and the camera of the brightness meter device is aimed at the test position of the license plate 21, and then the subsequent test work can be started.

[0060] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
