CROSS REFERENCES TO RELATED APPLICATION This application claims priority to Chinese Patent Application No. 2023110077047, filed on August 11, 2023, entitled "Vehicle, Laser Radar Mounting Bracket and Mounting Structure Thereof", the entire contents of which are incorporated herein by reference. TECHNICAL FIELD The present invention relates to the field of laser radar mounting technology, and more particularly to a vehicle, a laser radar mounting bracket, and a mounting structure thereof. BACKGROUND With the rapid development of autonomous driving technology, according to the "Classification of Driving Automation for Automobiles" standard, autonomous driving levels are classified into L0 (emergency assistance), L1 (partial driving assistance), L2 (combined driving assistance), L3 (conditional autonomous driving), L4 (highly automated driving), and L5 (fully automated driving). Currently, the industry trend is that vehicles at Level L2 and above are equipped with a plurality of sensors such as cameras and laser radar (LiDAR). Laser radar scans the surrounding environment by rapidly and repeatedly emitting laser beams to obtain "point cloud" data reflecting the shape, the position, and the movement of one or more objects in the surrounding environment. Laser radar used in vehicles emits laser having wavelengths of 905nm and 1550nm. The advantage of lasers is their focusing, preventing dispersion over long distances. However, this makes them unable to bypass obstacles and they suffer significant interference, even malfunctioning, in rain, fog, or sandstorms. Therefore, the market trend and demand is to fully integrate externally mounted laser radar into the interior of the vehicle, particularly onto an inner surface of a front window glass.
