The invention discloses a rear mounting point reinforcing structure of a front sub-frame. The rear part of the front sub-frame is connected with a sub-frame rear mounting base fixed on a vehicle body; a reinforcing bracket is arranged on the sub-frame rear mounting base; the rear part of the front sub-frame is connected with the reinforcing bracket. According to the rear mounting point reinforcing structure disclosed by the invention, a reinforcing bracket is arranged at the rear mounting point of the front sub-frame, so that the connection between the front sub-frame and the vehicle body is reinforced, and the connecting stiffness between the front sub-frame and the vehicle body is enhanced; especially in the Z direction, the control of engine excitation and road excitation in the Z direction is facilitated, so that the vibration transferred to the vehicle body through the sub-frame can be effectively controlled; under the condition that the requirements for strength and dynamics are met, the NVH performance is improved; besides, the reinforcing bracket is small in size, light in weight, convenient in spatial arrangement, and low in cost; because the reinforcing bracket can be designed according to the arrangement space and the size of the vehicle body, the universality is high.
