[0024] The following will further elaborate on the present utility model in conjunction with the Figures 1-4 accompanying drawings.

[0025] An embodiment of the present utility model discloses an installation bracket for the structure of a CNG gas cylinder box of a truck.

[0026] Referring to Figures 1-4 , an installation bracket for the structure of a CNG gas cylinder box of a truck includes an installation bracket 2 and a bracket assembly 7. The installation bracket 2 is fixedly arranged on the longitudinal beam 1 of the vehicle frame. A clamping member is arranged on the installation bracket 2, and the clamping member is used for clamping the CNG gas cylinder 4. The bracket assembly 7 is fixedly arranged on the installation bracket 2. The installation stiffness of the installation bracket 2 meets the requirements for gas cylinder installation, reduces the vibration of the gas cylinder, and ensures that the gas cylinder will not shake or fall off during driving, meeting the requirements of the gas cylinder installation strength (GB19239 - 2022) regulation test for gas vehicles.

[0027] In this embodiment, the installation bracket 2 is fixedly connected to the longitudinal beam 1 of the vehicle frame through bolts to complete the Z - direction constraint.
