Detailed Description

Embodiments of the present invention are exemplarily described below. As those skilled in the art will appreciate, the illustrated embodiments may be modified in various different ways without departing from the inventive concept. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive. In the following, the same reference numbers generally indicate functionally identical or similar elements.

Fig. 1 schematically shows a test fixture 1 for a vehicle lamp according to the present invention. This utensil 1 is examined to car light has: a carrier 20, on which carrier 20 a reference 21 is provided; a first supporting unit 30 for supporting a vehicle lamp to be detected; a second support unit 40 for supporting the vehicle contour 2 for the vehicle lamp; a third supporting unit 60 for holding the detecting device 70, wherein the first supporting unit 30, the second supporting unit 40, and the third supporting unit 60 occupy predetermined positions on the carrier 20 with respect to the reference base 21.

As can be seen in fig. 1, the carrier 20 is plate-shaped and is made of, for example, a metal plate, such as an aluminum plate. A reference 21 is provided at a corner of the carrier 20. The vehicle cam 2 has a tab 2A connected to the second support unit 40 and a body 2B, which is annular and in which a lamp to be detected is located in a space enclosed by the body 2B.

The respective support unit comprises at least one support element having a predetermined height dimension, wherein the third support elements of the third support unit 60 each have a positioning structure 65 for the detection device 70, so that the detection device 70 can measure the parameter relating to the vehicle lamp in a correctly positioned manner.

In fig. 1 it is schematically shown that a first supporting unit 30 for a vehicle lamp comprises two supporting

elements

31A, 31B; the second supporting unit 40 for the vehicle cam 2 comprises four supporting

elements

41A, 41B, 41C, 41D; the third supporting unit 60 for the detecting device 70 includes 8 supporting

members

61A, 61B, 61C, 61D, 61E, 61F, 61G, 61H. It is noted that the support elements of the respective support units described above may have different geometrical configurations from each other, such as a cylindrical, bent, forked, etc., as long as the respective support functions are fulfilled. The above numbers are merely exemplary, and a desired number of support elements may also be selected according to actual needs. Although it is shown that the first support unit 30 for the vehicle lamp is arranged in the middle, the second support unit 40 for the vehicle cam 2 is arranged around the first support unit 30, and the third support unit 60 for the detection device 70 is in turn arranged around the second support unit 40, other arrangements of the respective support units 40 can also be realized, depending on the shape of the particular vehicle lamp, for example the support elements of the respective support units can be arranged linearly.

In order to achieve a connection between the support unit and the respective support element to be supported (e.g. vehicle lamp, vehicle cam), a screw connection can be used, for example. For this purpose, threaded holes and/or positioning holes (for better clarity of illustration, no reference numerals have been added to them in the figures) may be provided at the top of the respective support elements of the support unit. The orientation of the top surface matches the orientation of the relevant part of the support to be supported.

In the example shown, the positioning structure 65 provided in the support element of the third support unit 60 is in the form of a guide hole. Therefore, the detection device 70 can be directly installed in the guide hole for detection. The detection device 70 is, for example, a dial indicator, which can be used to detect deviations between the actual and the theoretical course of the circumferential profile of the vehicle lamp to be detected. To this end, the third support unit and the positioning structure therein may be arranged and oriented with reference to a theoretical run of the desired circumference of the vehicle lamp. In particular, the positioning structures in different support elements may have different orientations from each other.

Fig. 3 shows a third support element 61H of the third support unit 60 with the detection device 70 arranged thereon. The third support element 61H has an L-shaped body 62, wherein one leg is provided with a through hole 63 for screwing with the carrier 20 and the other leg has a bevel 64 at the top end, the guide hole being perpendicular to the bevel 64. The positioning and orientation of the guide hole is set according to the above-mentioned reference datum 21. After the guide sleeve 73 of the dial indicator is fitted into the guide hole, its feeler 72 is brought into movable contact with the vehicle lamp to be checked in the direction M shown, and its display gauge 71 displays the measured value on the basis of which it is possible to know whether the peripheral profile of the vehicle lamp produced is within tolerance.

In addition, the test fixture 1 for a vehicle lamp has a pressing unit 50, which pressing unit 50 fixes the vehicle lamp to the first support unit 30 for the vehicle lamp in a manner that prevents it from being loosened. In the illustrated example, three partial

pressing units

51A, 51B, 51C of the pressing unit 50 are schematically illustrated, which are arranged distributed in the circumferential direction between the associated support elements 61A to 61H, as a result of which a relatively compact construction of the test element 1 for a vehicle lamp can be achieved.

In fig. 4, a single sub-pressing unit 51A is shown, which includes a holder 52 and a pressing mechanism 80 disposed on the holder 52. The support 52 is also L-shaped, one leg of which is provided with a through hole 53 for screwing with the carrier 20, and the other leg is provided with a hold-down mechanism 80 at the top end 54. The pressing mechanism 80 is a lever type structure having an operating lever 81, a transmission chain 82, and a pressing head 83, wherein the operating lever 81 is movable in the illustrated direction R, and the transmission chain 82 transmits the movement of the operating lever 81 to the pressing head 83 so that the pressing head 83 can be pressed against or moved away from a surface L of a vehicle lamp to be tested, which is schematically illustrated. The ram 83 may be fixedly attached to the transfer chain 82 or may be integrally formed with the transfer chain 82.

Furthermore, the fixture 1 for a vehicle lamp can also have a carrier 10, which carrier 10 serves to hold the carrier 20 together with the respective support unit on the carrier 20, wherein the carrier 10 is arranged such that the lamp at the fixture 1 for a vehicle lamp is oriented according to the actual position in the vehicle. Therefore, the detection tool for the vehicle lamp can be used for optical tests and the like, so that the application of the detection tool for the vehicle lamp is expanded. Preferably, the support comprises 2L-shaped pieces to achieve as light a weight of the gauge as possible while ensuring structural strength.

The present invention is not limited to the above configuration, and various other modifications may be adopted. While the invention has been described with respect to a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that other embodiments can be devised which do not depart from the scope of the invention as disclosed herein. Accordingly, the scope of the present invention should be limited only by the attached claims.
