Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp brackets, in particular to a hydrogen fuel bus headlamp structure which is easy to maintain. Background Art

[0002] The headlights of new energy buses such as hydrogen fuel city buses are located on the lower side of the front enclosure. The options mainly include a headlight assembly composed of low beam, high beam and turn signal, and two types of installation of these three functional lamps. The former has a more beautiful appearance and can be designed in a variety of forms. The production line installation and fixing method is more convenient. The latter has a relatively simple design selection and a lower procurement cost, because the lamps can be replaced independently, and the later maintenance cost is much lower than the installation of the combined lamp assembly.

[0003] In the design process of the front enclosure, while considering the function, aesthetics, and workmanship, the cost of later maintenance and replacement is also an important design input. At the same time, due to the shape of the front enclosure of the vehicle, the headlights are more easily damaged during operation due to vehicle collisions and other reasons than other parts, and need to be repaired and replaced frequently.

[0004] At present, the replacement of headlights mainly relies on the maintenance space formed after the front inspection door is opened, or by reaching in from the bottom of the vehicle for maintenance. Since there are structural components such as air filters, wiper kettles, trailer hooks, steering mechanisms, various water and gas pipelines, high and low voltage wiring harnesses, etc. inside the front vehicle body, the front inspection space is not wide. Feedback from various maintenance service stations shows that it is still cumbersome for operators to replace headlights. This phenomenon causes a more complicated maintenance process for the later maintenance of headlights, affects the convenience of operation, and has high requirements on the personal technical level and personal responsibility of the operator. There are quality risks. Therefore, a hydrogen fuel bus headlight structure that is easy to maintain is provided. Utility Model Content
