Abstract

The invention provides a trailer tail lamp test device, which comprises a power supply, wherein the power supply comprises a storage battery (1) and a commercial power cable (2) and is converted through a power supply conversion switch (4), the commercial power cable (2) is used for connecting commercial power with a 24VDC switching power supply (3) and outputting 24V voltage to be connected withthe conversion switch (4), a safety device (5) is connected behind the conversion switch (4), the positive electrode of a power supply signal lamp L6 (6) is connected with the current outflow end of the safety device (5), and the negative electrode of the power supply signal lamp L6 (6) is connected with a common end. In the prior art, a tail lamp system test can be carried out only when a traileris connected with a test main vehicle, and the trailer needs to be separated from the test main vehicle after the test is completed, so that time and labor are greatly consumed. According to the invention, the trailer tail lamp test device is suitable for trailer tail lamp tests, the design is carried out on the basis of a previous test method, and the problems that the previous test occupies toolarge space, the test efficiency is low, and time and labor are wasted in the test are solved; and the trailer tail lamp test device is convenient to carry, eliminates tail gas pollution caused by the test of the main vehicle, and reduces the cost of the trailer tail lamp test to a great extent.

Description

technical field [0001] The invention belongs to a hanging light tail light test device, which is suitable for the tail light test of a trailer. The tail light test can be carried out under the condition of mains power supply, and the tail light test of the trailer can also be carried out under the condition of battery power supply. Background technique [0002] With the development of technology, the mass production of trailers has become a trend, and the test of trailer taillights has become an inevitable problem. Previously, 4-5 people were needed for the trailer taillight test, so that the trailer was connected to the main vehicle for the test, and the trailer taillight test could only be carried out after the main vehicle supplied power to the trailer. manpower. In order to solve the above problems, this device is designed. The device has the characteristics of small size and portability, and eliminates the tail gas pollution produced by the test main vehicle due to th...
