The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements.

[0024] The present utility model provides a high-strength automobile front bulkhead.

[0025] Embodiment 1:

[0026] As Figure 1 shown, it includes a front bulkhead middle crossbeam 1. The top of the front bulkhead middle crossbeam 1 is fixedly connected with a front bulkhead upper panel 2, and the bottom of the front bulkhead middle crossbeam 1 is fixedly connected with a front bulkhead lower panel 3. The vertical height of the side of the front bulkhead upper panel 2 is lower than the vertical height of the side of the front bulkhead lower panel 3, that is, the front bulkhead middle crossbeam 1 is located in the middle-upper part and corresponds to the top of the engine. Moreover, both the front bulkhead upper panel 2 and the front bulkhead lower panel 3 are inclined. The front bulkhead upper panel 2 and the front bulkhead lower panel 3 are respectively welded to the body of the automobile. The side view of the front bulkhead upper panel 2, the front bulkhead middle crossbeam 1 and the front bulkhead lower panel 3 presents a shape like a tick, so the strength is higher. And after being impacted, the engine moves backward, and the inclined front bulkhead lower panel 3 can guide the engine to the bottom of the vehicle, thereby buffering the impact force and avoiding the problem that the engine pushes the front bulkhead into the cab.

[0027] Preferably, the side shape of the front bulkhead lower panel 3 is arched. When the engine sinks along the front bulkhead lower panel 3, the arched front bulkhead lower panel 3 has higher strength, thereby reducing the deformation degree of the front bulkhead lower panel 3 and ensuring that the engine can sink smoothly.

[0028] Preferably, a plurality of reinforcing ribs 11 are fixedly connected to the inner walls of the middle front cross member 1, the upper front panel 2 and the lower front panel 3 to strengthen the front panel and reduce the overall deformation after being impacted.

[0029] As Figure 2 shown, the top view shape of the middle front cross member 1 is arched, which further improves the strength of the middle front cross member 1 so that it can withstand stronger impact forces.

[0030] Embodiment 2:

[0031] As Figure 1 shown, on the basis of Embodiment 1, connecting rods 4 are fixedly connected to both ends of the middle front cross member 1, and a reinforcing beam 5 is fixedly connected between the two connecting rods 4. When the impact force received by the middle front cross member 1 is too large and causes serious deformation, the reinforcing beam 5 can support the middle front cross member 1, thereby reducing the deformation of the middle front cross member 1. The shape of the reinforcing beam 5 is arched, and the arched reinforcing beam 5 has higher strength.

[0032] Preferably, a plurality of support rods 51 are fixedly connected to one side of the reinforcing beam 5, and the ends of the support rods 51 far away from the reinforcing beam 5 are fixedly connected to the inner wall of the middle front cross member 1 to comprehensively support the middle front cross member 1, thereby further improving the firmness of the middle front cross member 1.

[0033] The working principle of the present utility model is as follows: When in use, the upper front panel 2, the middle front cross member 1, the lower front panel 3 and the connecting rod 4 are all welded to the vehicle body. When the vehicle is strongly impacted, the engine of the vehicle moves backward. After the top of the vehicle engine collides with the middle front cross member 1, the vehicle engine starts to tilt. When the vehicle engine continues to move backward, it will move downward along the inclination direction of the lower front panel 3, thereby avoiding the problem that the front panel rigidly bears the thrust of the engine and causes serious deformation and intrusion into the cab.

[0034] Compared with the prior art, the present utility model has the following beneficial effects compared with the prior art:

[0035] 1. The upper front panel 2 and the lower front panel 3 are inclined, so that the upper front panel 2, the middle front cross member 1 and the lower front panel present a shape like a checkmark, thus having higher strength. Therefore, it can withstand stronger impact forces. After the engine moves backward, the middle front cross member 1 supports the top of the engine, then the force on the engine is offset, and it will tilt downward and sink along the lower front panel 3, thereby guiding the engine to the bottom of the vehicle, buffering the impact force, avoiding the problem that the engine pushes the front panel to invade the cab and causing leg injuries to the front row passengers in the vehicle, and improving safety.

[0036] 2. By setting the lower front panel 3 as an arch shape, during the process of engine sinking, the lower front panel 3 can provide stronger support for the engine, thereby reducing the deformation of the lower front panel 3 and ensuring that the engine can sink smoothly.

[0037] 3. By setting the middle cross beam 1 of the front panel as an arch shape, the strength of the middle cross beam 1 of the front panel is improved, avoiding the problem that the middle cross beam 1 of the front panel deforms and jams the engine when the engine moves backward, resulting in the engine being unable to sink smoothly.

[0038] 4. The setting of the strengthening beam 5 provides stronger supporting force for the middle cross beam 1 of the front panel, thereby further improving the strength of the middle cross beam 1 of the front panel, ensuring that the middle cross beam 1 of the front panel will not have large deformation after being impacted, so that the top of the lower front panel 3 connected to the middle cross beam 1 of the front panel will not have large deformation, and thus ensuring that the engine can sink smoothly.
