This utility model provides a car roof handle and vehicle based on a four-bar linkage, belonging to the field of automotive parts technology. It includes: a base with a proximal hinge and a distal hinge, located at different positions along the depth of the base; one end of a first rocker arm hinged to the proximal hinge of the base, and the other end of the first rocker arm hinged to a connecting arm; one end of a second rocker arm hinged to the distal hinge of the base, and the other end of the second rocker arm hinged to a connecting arm; the connecting arm is hinged to the handle body. The first rocker arm, the second rocker arm, the connecting arm, and the base constitute a four-bar linkage. The advantages of this utility model are: the four-bar linkage allows for extension and retraction between the handle body and the base, enabling the handle body to be retracted and close to the base when not in use, and extended when in use, saving interior space and adapting well to bumpy driving environments.

The application provides a front engine compartment assembly and a vehicle. The front engine compartment assembly comprises a wheel cover structure, a front longitudinal beam, a front bulkhead and an annular frame structure. The wheel cover structure and the front longitudinal beam are located on both sides of the vehicle body. The annular frame structure is arranged between the opposite wheel cover structures and connected with the front bulkhead. The two ends of the annular frame structure respectively extend downward along the inner walls of the corresponding wheel cover structures until connected with the front longitudinal beam. The front engine compartment assembly can improve the stress resistance and force transmission efficiency of the front engine compartment assembly, thereby improving the driving comfort of the vehicle.
