Description

Technical Field

[0001] The utility model relates to the technical field of commercial vehicle lamps, in particular to a vibration detection fixture for a bulb mounting base. Background Technique

[0002] At present, when determining the quality of commercial vehicle lamp bulbs, it is necessary to detect the vibration resistance performance of the lamp bulbs. There are currently two test methods:

[0003] First, the bulb is installed inside the lamp assembly, and the lamp is fixed on the vibration platform through the mounting fixture. After the lamp is lit, it is tested according to the vibration frequency, vibration amplitude and other parameters specified in the environmental durability regulations for external lighting and light signal devices of road vehicles. Since the bulb is installed inside the lamp, after the movable connecting parts inside the lamp are worn and shaken during vibration, the acceleration borne by the bulb will be too large or insufficient, affecting the result judgment.

[0004] Second, the made bulb fixing fixture has a universal model for the fixing block and the pressing block. The pressing block presses the bulb, which is inconsistent with the actual positioning of different models of bulbs in the lamp and the axial direction of commercial vehicle driving, resulting in poor reliability of the detection results. Summary of the Invention

[0005] The purpose of the utility model is to provide a vibration detection fixture for a bulb mounting base, which cancels the bulb fixing block and the pressing block, and adopts the same positioning at the bulb mounting position of the internal reflector of the lamp and the axial direction of the center of commercial vehicle road driving, so as to realize a stable and reliable rigid connection between the automotive bulb and the fixture during the test process, and improve the reliability of the detection results.

[0006] In order to solve the above technical problems, the technical solution of the utility model is as follows:

[0007] A vibration detection fixture for a bulb mounting base, including a vibration disk fixture body, the vibration disk fixture body is fixedly installed on a vibration workbench, and is characterized in that: the vibration disk fixture body is of a cavity structure, a connecting disk is provided at the bottom of the vibration disk fixture body, the connecting disk is provided with a first group of through holes, and the first group of through holes is communicated with the platform of the vibration workbench, and an annular outer wall is provided along the circumference of the connecting disk of the vibration disk fixture body, and a bulb is installed on the annular outer wall.

[0008] Improvement to the above technical solution: a second group of through holes and threaded holes are provided on the side wall of the annular outer wall, a bulb positioning disk mounting base is provided in the second group of through holes, and the positioning disk of the bulb is installed on the annular outer wall through the mounting base.

[0009] Further improvement to the above technical solution: the mounting base passes through the second group of through holes and is fixed in the threaded holes of the annular outer wall through bolts and connected as a whole.

[0010] Further improvement of the above technical solution: The installation base includes a positioning disk seat groove for installing the bulb, through holes are provided around the base centered on the base, and the positioning groove indicates the vibration direction of the bulb installation shaft.

[0011] Further improvement of the above technical solution: Ten second-group through holes are evenly arranged on the annular outer wall of the vibrating disk fixture body. Beneficial effects

[0012] When using a vibration detection fixture for a bulb installation base of the present utility model, each bulb is directly connected to an external power supply through a connector wire harness. Without arranging a terminal post, accurate detection requirements for the bulb performance are achieved. Stable and reliable connection with the fixture during the automotive bulb test is realized, which is consistent with the actual vehicle; the fixed block and pressing block in the prior art are cancelled, and an installation base structure is adopted, which is consistent with the positioning at the bulb installation part of the internal reflector of the lamp and the center axis direction of the commercial vehicle road driving; the installation base for different types of bulbs can be extended and manufactured and directly applied to the fixture body structure, reducing the investment cost of new fixtures.
