In the prior art, the foam layer is arranged at the bottom of the battery pack, so that the defects of high manufacturing cost and high disassembly and maintenance cost are also caused.
In the embodiment of the present invention, referring to fig. 1, fig. 1 shows a schematic view of a partial structure of a vehicle according to an embodiment of the present invention, fig. 1 mainly shows a front subframe 1, a battery pack protection plate 2 and a battery pack 3 on the vehicle, and other components of the vehicle are not shown, this embodiment provides a battery pack protection plate, which is applied to the vehicle, the vehicle specifically may include a vehicle body, a front subframe 1, a battery pack 3 and a battery pack protection plate 2, the front subframe 1 and the battery pack 3 are respectively connected below the vehicle body, the battery pack protection plate 2 includes a first end and a second end, the first end is opposite to the second end, the first end is used for being connected to the rear side of the front subframe 1, and the second end is used for being connected to the battery pack 3; the battery pack protection plate 2 is obliquely arranged, and the distance between the first end and the vehicle body is smaller than that between the second end and the vehicle body; the length of the battery wrap protection plate 2 in the second direction gradually increases along the first direction, the first direction is a direction from the first end to the second end, and the second direction is perpendicular to the first direction.
In practical application, the sub-frame can be regarded as a framework of the front axle and the rear axle and is a component of the front axle and the rear axle, the sub-frame is not a complete frame and is a bracket for supporting the front axle and the rear axle and the suspension, so that the front axle and the suspension are connected with the front frame through the sub-frame, the sub-frame is conventionally called as an auxiliary frame, and the sub-frame has the function of isolating vibration and noise and reducing the direct entering of the front axle and the rear axle into a carriage. The front auxiliary frame is a bracket for supporting the front axle and suspending.
In practical application, the front subframe 1 and the battery pack 3 are respectively installed below a vehicle body, the vehicle head is used as the front, the vehicle tail is used as the rear, the front subframe 1 is located in front of the battery pack 3, the battery pack protection plate 2 is located between the front subframe 1 and the battery pack 3, a first end (front end) of the battery pack protection plate 2 is connected with the rear side of the front subframe 1, a second end (rear end) of the battery pack protection plate 2 is connected with the battery pack 3, the battery pack 3 is obliquely arranged, and the distance between the front end of the battery pack protection plate 2 and the vehicle body is smaller than that between the rear end of the battery pack protection plate 2 and the vehicle body, that is, the distance between the front end of the battery pack protection plate 2 and the ground (called as the ground clearance of the front end of the battery pack protection plate 2) is greater than that between the rear end of the battery pack protection plate 2 and the ground (called as the ground clearance of the rear end of the battery pack protection plate 2). It should be noted that the distances between the battery pack cover 2 and the vehicle body and the ground are compared with each other by regarding the vehicle body and the ground as two horizontal planes.
Specifically, when the vehicle runs, if there is a raised obstacle on the ground where the front part of the vehicle runs, because the battery pack protection plate 2 is in front of the battery pack 3, the obstacle will collide with the battery pack protection plate 2 in front, because the battery pack protection plate 2 is inclined relative to the ground, and the ground clearance of the front end of the battery pack protection plate 2 is greater than the ground clearance of the rear end of the battery pack protection plate 2, therefore, the obstacle can lift the entire vehicle gradually, the front end of the battery pack 3 is prevented from being damaged by the front collision of the obstacle, the sealing performance of the battery pack 3 can be protected, and the running safety is improved, and compared with the prior art, the battery pack protection plate 2 of the present embodiment does not reduce the ground clearance of the battery pack, and the foam layer is prevented from being added at the lower end of the battery pack to reduce the ground clearance of the battery pack 3 in order to protect the battery pack 3, a phenomenon that affects the trafficability of the vehicle.
In practical application, because the front end of the battery pack protection plate 2 is collided before the barrier, abnormal sound can be generated in the collision, and at the moment, a driver can stop the vehicle or back the vehicle in time to avoid the battery pack 3 from being damaged, so that the battery pack protection plate 2 of the embodiment also has the effect of preventing the battery pack 3 from being collided. Of course, even if the driver does not stop the vehicle or backs the vehicle, the battery pack protection plate 2 is obliquely installed in the embodiment, so that the front end of the battery pack 3 is prevented from being damaged due to frontal impact of the obstacle, if the vehicle speed is high, the obstacle can lift the whole vehicle, and since the battery pack protection plate 2 has a contact stroke with the obstacle (the length of the battery pack protection plate 2 in the first direction), the vehicle may cross the obstacle and land, and in the process, the battery pack 3 also crosses the obstacle.
