In recent years, with the rapid development of my country's economy and automobile industry, people's requirements for the quality feeling, quality requirements, performance requirements, and smooth, beautiful and dynamic body shape of automobiles are increasing day by day. The performance requirements of the engine cover are also increasing. The engine cover lock hook reinforcement plate is located in the middle of the inner and outer panels of the engine cover. It is mainly used for welding the lock hook with itself and then with the inner panel of the front hatch cover to connect the engine cover with the lock body and ensure the stability and reliability of the overall connection between the engine cover and the body.

The inventor of the present application noticed that most of the current engine cover reinforcement plates are made of aluminum, and the structural performance of the connection between the steel lock hook and the aluminum engine cover reinforcement plate is relatively weak. During the driving process of the vehicle, the engine cover will vibrate at this position. Moreover, after the steel lock hook is connected to the aluminum engine cover reinforcement plate, because the aluminum material is relatively soft, the aluminum engine cover reinforcement plate is prone to tearing when the lock hook is stressed.

The inventors of the present application have discovered through research that the structural performance at the connection position of the hood lock hook can be greatly enhanced by replacing the material of the plate body at the joint with the bonnet lock hook with steel material, effectively alleviating the vibration of the engine hood at this position. The steel plate body is connected to the aluminum engine hood reinforcement plate by bolts, which can make the connection between the steel plate body and the aluminum material plate body more firm.

In order to solve the existing technical problems, the embodiment of the present application provides a hood latch assembly, a reinforcement plate assembly, an engine hood assembly and a vehicle. Fig. 1 is a schematic diagram of explosion of the latch assembly provided by some embodiments of the present application, and Fig. 2 is a schematic structural diagram of the latch assembly provided by some embodiments of the present application.

As shown in FIG. 1 and FIG. 2 , the embodiment of the present application provides a bonnet hook assembly 100 for connecting the reinforcing plate 200 to the hood. The bonnet locking hook assembly 100 includes a connecting plate 110 and a locking hook 120 . The connecting plate 110 is attached to the side surface of the reinforcing plate 200 . By extension, the stiffness of the connection plate 110 is greater than the stiffness of the reinforcing plate 200 .

The material of the locking hook 120 and the connecting plate 110 of the engine cover locking hook assembly 100 adopted in the embodiment of the present application can be steel, and the rigidity of the connecting plate 110 is greater than that of the reinforcing plate 200 . When both the lock hook 120 and the connection plate 110 are made of steel, the lock hook 120 can be connected to the connection plate 110 by carbon dioxide shielded welding to form the lock hook assembly 100, so that the structural performance of the connection between the lock hook 120 and the connection plate 110 is greatly enhanced. Specifically, the connecting plate 110 is positioned on the side surface of the reinforcing plate 200 close to the outer panel of the engine cover, the joint 121 of the locking hook 120 is clamped between the connecting plate 110 and the reinforcing plate 200 , and the hook body 122 of the locking hook 120 extends through the reinforcing plate 200 . Exemplarily, the joint 121 of the locking hook 120 can be connected to the surface of the connecting plate 110 close to the reinforcing plate 200 by means of carbon dioxide shielded welding.

The lock hook is fixedly connected with the high rigidity connecting plate 110 to form the engine cover lock hook assembly 100, which strengthens the structural performance at the connection position of the engine cover lock hook.

In some embodiments, the connecting plate 110 includes a first section 130 and a second section 140 located on both sides of the first section 130 along the length direction, the first section 130 is formed by being recessed downward relative to the second section 140, the first section 130 is provided with a locking hook receiving portion 150, and the joint 121 is accommodated and fixedly connected to the locking hook receiving portion 150.

Since the engine cover hook assembly 100 in the embodiment of the present application is connected to the engine cover through the reinforcement plate 200, the reinforcement plate 200 is connected with the engine cover outer panel and the engine cover inner panel. Since the structure of the engine cover outer panel and the engine cover inner panel itself is not smooth, the reinforcement plate 200 itself is also set to have a concave-convex structure to better fit the shape of the contact surface between the engine cover outer panel and the engine cover inner panel in order to better assemble between the engine cover inner and outer panels.

Therefore, in the embodiment of the present application, the connecting plate 110 is stamped to form a first concave-convex structure having the first section 130 and the second section 140, so that when the connecting plate 110 is fixedly connected to the reinforcing plate 200, the connecting plate 110 can better fit the shape of the contact surface of the reinforcing plate 200, and the firmness of the fixed connection between the connecting plate 110 and the reinforcing plate 200 can be improved. Specifically, the first section 130 is located in the middle area of the connecting plate 110, and the second section 140 is located on both sides of the first section 130 along the length direction of the connecting plate 110, wherein the first section 130 is deeper in depression than the second section 140, that is, the connecting plate 110 is a second concave-convex structure protruding from both sides of the middle depression along the length direction. The locking hook receiving part 150 is arranged on the first section 130 of the connecting plate 110. The function of the locking hook receiving part 150 is to accommodate the joint 121 of the locking hook 120, and the joint 121 is fixedly connected with the locking hook receiving part 150 by carbon dioxide shielded welding, so that the locking hook 120 and the connecting plate 110 form the locking hook assembly 100.

The joint 121 of the lock hook 120 is wrapped and fixed by welding by setting the lock hook receiving part 150, which can increase the contact area between the joint 121 of the lock hook 120 and the connection plate 110, thereby improving the welding firmness of the lock hook 120 and the connection plate 110, and greatly increasing the structural performance at the connection position between the lock hook 120 and the connection plate 110.

In some embodiments, the locking hook accommodating portion 150 includes a first sub-accommodating portion 151 and a second sub-accommodating portion 152 extending along the length direction of the connecting plate 110 and parallel to each other. The connecting plate 110 further includes a reinforcing structure 160 extending along the length direction of the connecting plate 110 and located between the first sub-accommodating portion 151 and the second sub-accommodating portion 152 . The reinforcing structure 160 and the connecting plate 110 are integrally formed.

In the embodiment of the present application, the lock hook 120 includes two mutually parallel joints 121, and the lock hook receiving portion 150 includes a first sub-accommodating portion 151 and a second sub-accommodating portion 152 extending along the length direction of the connecting plate 110 and parallel to each other. The function of the reinforcing structure 160 is to increase the structural strength of the connecting plate 110 , and the reinforcing structure 160 is integrally formed with the connecting plate 110 by stamping. Specifically, the stress generated by the vibration of the locking hook 120 is transmitted to the connecting plate 110 through the joint 121, and the reinforcing structure 160 is arranged between the first sub-accommodating portion 151 and the second sub-accommodating portion 152 to separate the first sub-accommodating portion 151 and the second sub-accommodating portion 152, avoiding stress concentration at the connecting position between the locking hook 120 and the connecting plate 110, and effectively improving the structural performance at the connecting position between the locking hook 120 and the connecting plate 110.
