TECHNICAL FIELD

[0001] The present application relates to the technical field of commercial vehicle structure, in particular to a mounting structure of a urea pump fixing support. BACKGROUND

[0002] In the current commercial vehicle, the urea pump is fixed on the urea tank through a support, and in order to ensure the fixing quality of the urea pump, the fixing support of the urea pump needs to be designed.

[0003] A patent with application number 202111169762.0 and title "An integral type pipeline elastic support hanger" discloses an integral type pipeline elastic support hanger. The support hanger comprises a gland, a base and a cushion block. The inner side of the gland and the base are both arranged with sawtooth grooves, which support and clamp the pipeline by being spaced apart from each other. The cushion block is arranged between the gland and the base. The two ends of the gland are connected together through fasteners and the base to fix the pipeline. The base has a fastening nut which is sleeved on a limiting block. The gland is composed of an upper clamp and an upper clamp vulcanization layer. The upper clamp is wrapped with the upper clamp vulcanization layer and is integrally vulcanized. The upper clamp vulcanization layer is provided with an array of sawtooth grooves to elastically clamp the pipeline. The base is composed of a lower clamp, a lower clamp vulcanization layer, a limiting block, a fastening nut and a clamp bottom plate. The lower clamp vulcanization layer wraps the lower clamp, the limiting block, the fastening nut and the clamp bottom plate and is integrally vulcanized. The limiting block which sleeves the fastening nut is arranged inside the two ends of the base to play the displacement compensation and damping effect. The array of sawtooth grooves elastically supports the pipeline.

[0004] A patent with application number 201320408993.7 and title "A urea pump fixing support" discloses a urea pump fixing support.
