Based on the embodiments in the present invention, all other embodiments obtained by the skilled person without creative work belong to the protection scope of the present invention.

The technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

Referring to fig. 1 and 2, an embodiment of the present invention provides a vehicle 1000, where the vehicle 1000 may be a pure electric vehicle, a hybrid electric vehicle, or the like. In other embodiments, the vehicle 1000 may also be other types of vehicles.

The vehicle 1000 includes a vehicle body frame 100 and a battery pack 200, and the battery pack 200 is mounted to the vehicle body frame 100, for example, the battery pack 200 may be mounted to the vehicle body frame 100 near the bottom of the vehicle. The battery pack 200 may provide power to the electric devices of the vehicle 1000.

The vehicle body frame 100 includes a vehicle battery pack protection device 10 and a frame main body 20, and the vehicle battery pack protection device 10 is mounted to the frame main body 20. The battery pack 200 may be mounted to the frame body 20, and the vehicle battery pack protective device 10 may provide protection to the battery pack 200.

The frame body 20 may include a main frame 21 and a sub-frame 22, and the main frame 21 is connected to the sub-frame 22. The battery pack 200 may be mounted to the main frame 21, and the vehicle battery pack guard 10 may be mounted to the sub-frame 22.

The subframe 22 may include a front subframe 221 and a rear subframe 222, and both the front subframe 221 and the rear subframe 222 are connected to the main frame 21. The front subframe 221 may be located near the front of the vehicle, and the rear subframe 222 may be located near the rear of the vehicle, such that the front subframe 221, the main frame 21, and the rear subframe 222 are sequentially distributed along the length of the vehicle 1000.

At least one of the front end sub frame 221 and the rear end sub frame 222 may be provided with the vehicle battery pack guard 10.

For example, the front subframe 221 may be provided with a vehicle battery pack guard 10 to provide protection in a forward direction of the battery pack 200, which helps to reduce the impact of the vehicle 1000 on the battery pack 200 during forward movement.

For another example, the rear subframe 222 may be provided with the vehicle battery pack protection device 10, so as to provide protection for the rear direction of the battery pack 200, and help reduce the collision of the vehicle 1000 on the battery pack 200 during the reversing process.

For example, as shown in fig. 3 and 4, the front subframe 221 and the rear subframe 222 may be provided with a vehicle battery pack protection device 10, so as to provide protection for the battery pack 200 in the front-rear direction of the vehicle 1000, which helps to reduce the collision of the battery pack 200 during the forward and reverse movement of the vehicle 1000.

Referring to fig. 5, the vehicle battery pack protection apparatus 10 includes a frame fixing member 11, a battery pack protection member 12, an elastic member 13 and a driver 14, wherein the elastic member 13 is connected to the frame fixing member 11 and the battery pack protection member 12, and the driver 14 is also connected to the frame fixing member 11 and the battery pack protection member 12.

The frame fixing 11 may be adapted to be fixed to the frame. The frame fixing member 11 may be fixed to the frame body 20, and for example, the frame fixing member 11 may be fixed to the subframe 22. In the case where the vehicle battery pack guard 10 is provided to both the front subframe 221 and the rear subframe 222, the frame fixing member 11 of the vehicle battery pack guard 10 is fixed to the front subframe 221, and the frame fixing member 11 of the vehicle battery pack guard 10 is fixed to the rear subframe 222.

The frame fixing member 11 and the front subframe 221 (or the rear subframe 222) may be fixed together by screws, bolts, rivets, welding or other fixing methods. In other embodiments, the frame fixing member 11 may be integrally formed with the bracket of the front subframe 221 (or the rear subframe 222), so that the frame fixing member 11 may serve as the structure of the front subframe 221 (or the rear subframe 222).

The frame mount 11 may have a substantially long plate-like structure, and the length direction of the frame mount 11 may be substantially the width direction of the vehicle 1000. The frame fixing member 11 may be provided with a plurality of fixing locations, and the plurality of fixing locations may be spaced apart along the length direction of the frame fixing member 11. The frame fixing member 11 may be fixed to the front sub frame 221 (or the rear sub frame 222) through a plurality of fixing positions, so as to improve stability of the connection of the frame fixing member 11 and the front sub frame 221 (or the rear sub frame 222).

The battery pack guard 12 is adapted to protect the battery pack 200. The battery pack guard 12 may be located on a side of the frame attachment 11 facing away from the frame body 20 such that the battery pack guard 12 may be located on a side of the frame attachment 11 facing the ground when the vehicle battery pack guard 10 is assembled to the vehicle body frame 100, so that the battery pack guard 12 protects the battery pack 200.

The battery pack guard 12 may be positioned lower than the battery pack 200 such that the distance from the battery pack guard 12 to the ground is less than the distance from the battery pack 200 to the ground, so that the battery pack guard 12 may collide with an obstacle before the battery pack 200, providing better protection for the battery pack 200. In addition, since the elastic member 13 is connected to the frame attachment 11 and the battery pack guard 12, the elastic member 13 may serve as an energy absorbing structure, and the elastic member 13 may diffuse the impact force transmitted from the battery pack guard 12 by its own elastic deformation and also help to buffer the impact force transmitted from the battery pack guard 12 to the frame attachment 11, so that the collision force of the vehicle 1000 caused by an obstacle may be attenuated.

The battery pack guard 12 is selectively positionable relative to the frame mount 11 at a first height position or a second height position, the first height position being lower than the second height position. Wherein the height of the battery pack guard 12 in the first height position and the height in the second height position are both lower than the height of the battery pack 200.

Under the condition that the battery pack protection piece 12 is located at the first height position, the battery pack protection piece 12 is located at a lower position, so that when the vehicle 1000 passes through an obstacle road such as a steep slope, a side slope, a step, a trench and the like in daily life, the current road condition can be prompted to the driver through the impact sound of the battery pack protection piece 12 and the obstacle, the driver can know whether the vehicle 1000 can pass through the obstacle road, the potential safety hazard is avoided, and the safety performance of the vehicle 1000 is optimized.

In addition, since the elastic member 13 is connected to the frame fixing member 11 and the battery pack guard 12, the battery pack guard 12 can be returned under the elastic force of the elastic member 13 after the battery pack guard 12 is impacted, so that the battery pack guard 12 does not need to be manually returned.

In the case where the battery pack protector 12 is located at the second height position, the distance between the battery pack protector 12 and the frame fixing member 11 is smaller, so that the vehicle battery pack protector 10 has a compact structure, which helps to reduce the occurrence of a large swing of the battery pack protector 12 caused by a high-speed driving condition of the vehicle 1000.

The battery pack guard 12 may be generally an elongated structure. The length direction of the battery pack guard 12 may be substantially the width direction of the vehicle 1000, which may improve the protection range of the battery pack guard 12 with respect to the battery pack 200, and contribute to further reducing the impact of the battery pack 200 with an obstacle.

The battery pack protection member 12 may include a connection portion 121 and a protection portion 122, and both the elastic member 13 and the driver 14 may be connected to the connection portion 121. The connecting portion 121 is connected to the protecting portion 122, for example, the protecting portion 122 may be connected to a side of the connecting portion 121 away from the elastic member 13. The protection part 122 is connected to the connection part 121 at an included angle, for example, the protection part 122 and the connection part 121 may be substantially perpendicular, so that the cross section of the battery pack protection part 12 may be substantially L-shaped. Thus, the structure of the battery pack protection member 12 is designed reasonably, which contributes to improving the protection effect of the battery pack protection member 12 on the battery pack 200.

At least one of the guard portion 122 and the connection portion 121 may be provided with a cavity 123.

For example, the guard portion 122 may be provided with a cavity 123, on the one hand, the cavity 123 contributes to reducing the weight of the guard portion 122, which in turn contributes to achieving a light weight of the vehicle 1000; on the other hand, the cavity 123 may serve as an energy absorption space, and may absorb an impact force generated when the protection portion 122 is collided, which is not only helpful to reduce the degree of deformation and bending of the protection portion 122, but also may reduce the impact force transmitted to the structure around the protection portion 122.

Further, for example, if connecting portion 121 may be provided with cavity 123, cavity 123 of connecting portion 121 may also contribute to reducing the weight of connecting portion 121, which may further contribute to reducing the weight of vehicle 1000, and may also serve as a energy absorbing space to absorb impact force when connecting portion 121 is subjected to a collision, which may reduce the degree of deformation and bending of connecting portion 121, and may also reduce the impact force transmitted to the structure around connecting portion 121.

For another example, the connecting portion 121 and the protecting portion 122 may both be provided with a cavity 123, and the cavity 123 of the connecting portion 121 may be communicated with the cavity 123 of the protecting portion 122.

The driver 14 is adapted to drive the battery pack protection member 12 to move from the first height position to the second height position, so that the battery pack protection member 12 can be driven by the driver 14 to move to a position more compact with the frame fixing member 11 in case the vehicle 1000 does not need to pass through an obstacle, for example, during high-speed running of the vehicle 1000, so as to adjust the height position of the battery pack protection member 12 according to actual conditions.

In the case where the driver 14 does not generate a driving force to the battery pack guard 12, and the telescopic end of the driver 14 does not generate a force member to the battery pack guard 12, the battery pack guard 12 may fall under the gravity and be able to move from the second height position to the first height position under the action of the elastic member 13.

In addition, when the driver 14 is torn or fails due to the impact on the battery pack protector 12, the elastic member 13 is connected to the frame fixing member 11 and the battery pack protector 12, so that the elastic member 13 can prevent the battery pack protector 12 from falling off due to the breakage of the driver 14.

The number of the actuators 14 may be two, two actuators 14 may be respectively spaced along the length direction of the frame fixing member 11, one actuator 14 may be connected to an end portion of the frame fixing member 11, the other actuator 14 may be connected to the other end portion of the frame fixing member 11, and the telescopic ends of the two actuators 14 are both connected to the battery pack protection member 12. As such, the two drivers 14 help improve the stability of the battery pack guard 12 moving from the first height position to the second height position.

The actuator 14 may be a telescopic actuator, the telescopic end of the actuator 14 may be connected to the battery pack guard 12, and the telescopic motion of the actuator 14 may move the battery pack guard 12 from the first height position to the second height position. In this manner, the battery pack guard 12 is facilitated to be quickly switched to different height positions, and the structure of the telescopic driver is simplified, which facilitates the simplification of the structure of the vehicle battery pack guard 10.

Wherein the driver 14 may be a hydraulic ram, an electric ram, or other types. In the case that the battery pack protection member 12 is required to be at the second height position, the push rod of the driver 14 can contract inward of the cylinder and move the battery pack protection member 12 from the first height position to the second height position.

In some embodiments, the vehicle battery pack protection device 10 may further include a controller 15, and the controller 15 may be in signal connection with the driver 14, for example, the controller 15 and the driver 14 may be electrically connected by a signal line. The controller 15 may control the driver 14 according to the input signal of the user, and then control the battery pack protection member 12 to be at different height positions.

In some embodiments, the number of the elastic members 13 may be multiple, a plurality of the elastic members 13 may be spaced along the length direction of the battery pack protection member 12, and each of the elastic members 13 may be connected between the frame fixing member 11 and the battery pack protection member 12. The plurality of elastic members 13 can help to improve the energy absorbing effect of the vehicle battery pack protection device 10, and can also help to improve the reliability of the overall structure of the vehicle battery pack protection device 10, so that the vehicle battery pack protection device 10 is not easy to cause the battery pack protection device 12 to fall off in the case of the driver 14 breaking. The elastic member 13 may be a tension spring, a compression spring, or other elastic structures.
