Detailed Description
Hereinafter, exemplary embodiments of the present utility model will be described in detail with reference to the accompanying drawings shown. The exemplary embodiments are examples and may be implemented in various forms by those skilled in the art. Thus, the present utility model is not limited to the exemplary embodiments described herein.
The intelligent gravity center adjusting system of the electric automobile comprises a control module 1, a driving module 2 and a power battery 3. The control module 1 judges the surrounding environment and driving state of the automobile based on the data of many sensors thereof, and then sends a center of gravity adjustment command to the drive module 2. The driving module 2 adjusts the position of the power battery 3 by adjusting the motor, thereby adjusting the center of gravity of the electric vehicle.
Control module
Fig. 1 shows a block diagram of a structure of an intelligent adjusting system for the center of gravity of an electric vehicle according to the present utility model, in which connection relations of components in a control module and a driving module are shown.
As shown in fig. 1, a control module 1 in an intelligent regulation system for the center of gravity of an electric vehicle according to the present utility model includes a center of gravity controller 11, and an information feedback part electrically connected to the center of gravity controller. As an example, as shown in fig. 1, the signal collecting means may include an advanced driving assistance system CAMERA (adas_camera) 12, a radar 13, a wheel speed sensor 14, a tire pressure sensor 15, a collision sensor 16, an electronic power steering system 17, a water sensor 18, and a brake sensor 19. Of course, the information feedback component may also include other sensors or electronic components. Alternatively, the information feedback component may not include some of the devices or sensors described above.
The center of gravity controller 11 receives signals or data from the respective components or sensors, calculates displacement data to be adjusted by the power battery 3, and sends a center of gravity adjustment command to the drive module 2 in accordance therewith. The gravity center controller 11 may be a general microprocessor or other special computing chip.
The advanced driving assistance system camera 12 is used to judge the flatness of the road and identify obstacles. Rolling and pitching conditions of the road and obstacles affect the driving stability. Accordingly, the video signal data provided by the advanced driving assistance system camera 12 is used as one of the input parameters for the center of gravity controller 11 to calculate the displacement required to be adjusted by the power battery 3.
The radar 13 is used for distance data that can measure obstacles. The obstacle affects the stability of driving of the vehicle. The distance data of the obstacle measured by the radar also constitutes one of the parameters used by the center of gravity controller 11 to calculate the displacement of the power cell 3.
The wheel speed sensor 14 is used to measure the vehicle speed. The vehicle speed directly affects the stability of the vehicle driving. For example, when the vehicle speed is high, lowering the center of gravity of the vehicle helps to improve the stability of the vehicle driving. Therefore, the vehicle speed measured by the wheel speed sensor 14 constitutes one of the parameters used by the center of gravity controller 11 to calculate the displacement of the power battery 3.
The tire pressure sensor 15 is for sensing the tire pressure. When the pressure of each tire differs greatly, uneven stress and thus uneven wear of each tire are caused. By adjusting the center of gravity of the vehicle, the stress distribution of each tire can be changed, which helps to overcome the defects. For example, when the tire pressure of one tire is too high, the power cell 3 will automatically be moved to a position away from the tire to prevent the tire from bursting. Thus, the tire pressure data measured by the tire pressure sensor 15 constitutes one of the parameters used by the center of gravity controller 11 to calculate the displacement of the power cell 3.
The collision sensor 16 is used to determine whether a collision has occurred. When a front/rear collision occurs, safety is facilitated by moving the power battery 3 backward (t+)/forward (T-) away from the collision region. Thus, the collision signal sensed by the collision sensor 16 constitutes one of the parameters used by the center of gravity controller 11 to calculate the displacement of the power cell 3.
The electronic power steering system 17 is used to sense the steering angle. Centrifugal forces generated by steering of the vehicle can affect the stability of the vehicle driving. Thus, the steering angle data constitutes one of the parameters used by the center of gravity controller 11 to calculate the displacement of the power battery 3.
The water sensor 18 is used to determine whether the car is falling into the water. When the car falls into the water, the battery 3 will automatically move downwards (H-) until it falls from the car, in order to reduce the weight of the car. So that the passenger has more time to escape the car. Thus, the information provided by the water sensor 18 constitutes one of the parameters that the center of gravity controller 11 uses to calculate the displacement of the power cell 3.
The brake sensor 19 is used to determine whether the vehicle is in an emergency braking state. When the automobile brakes, the center of gravity changes in both the high-low direction and the front-rear direction. The signal provided by the brake sensor 19 constitutes one of the parameters that the center of gravity controller 11 uses to calculate the displacement of the power cell 3.
Driving module

The height adjusting assembly 21, the front-rear adjusting assembly 22 and the left-right adjusting assembly 23 are respectively connected to the control module 1 of the gravity center intelligent adjusting system.
Fig. 2 shows the installation relationship of the structure of the driving module and the power battery 3 in the center of gravity intelligent regulation system of the electric vehicle according to the present utility model.
As shown in fig. 2, the driving module 2 includes 4 height adjusting assemblies 21,2 front-rear adjusting assemblies 22, and 1 left-right adjusting assembly 23. The height adjusting assembly 21, the front-rear adjusting assembly 22, and the left-right adjusting assembly 23 are respectively provided to the power cells 3 for adjusting the positions of the power cells 3 in the up-down direction, the front-rear direction, and the left-right direction, respectively.
As shown in fig. 2, the height adjustment assembly 21 includes a height adjustment motor 211 and a height displacement mechanism connected to the height adjustment motor 211, the height displacement mechanism being connected to the power battery 3. As an example, the high-low displacement mechanism in fig. 2 is a high-low lead screw-nut drive pair. Through the high-low screw-nut transmission pair, when the high-low adjusting motor 211 rotates forward or reversely, the power battery 3 is driven to move upwards or downwards. For example, the high-low screw-nut transmission pair includes a high-low screw 212 connected to the high-low adjustment motor 211, and a high-low nut 213 connected to the power battery 3, with which the high-low screw is engaged, as shown in fig. 3. Alternatively, the height drive pairs may take other forms, such as a rack-and-pinion drive pair.
As shown in fig. 2, the front-rear adjustment assembly 22 includes a front-rear adjustment motor 221 and a front-rear displacement mechanism connected to the front-rear adjustment motor 221, the front-rear displacement mechanism being connected to the power battery 3. As an example, the front-rear displacement mechanism in fig. 2 is a gear-rack transmission pair. The power battery 3 is driven to move forward or backward by the gear-rack transmission pair when the front-rear adjusting motor 221 rotates forward or backward. The rack-and-pinion gear pair includes a gear 222 connected to the front-rear adjustment motor 221 and a rack 223 connected to the power battery 3, as shown in fig. 4. Alternatively, the fore-aft displacement mechanism may take other forms, such as a lead screw-nut drive pair.
As shown in fig. 2, the left-right adjusting assembly 23 includes a left-right adjusting motor 231 and a left-right displacement mechanism connected to the left-right adjusting motor 231, the left-right displacement mechanism being connected to the power battery 3. As an example, the left-right displacement mechanism in fig. 2 is a left-right screw-nut drive pair. When the left and right adjusting motor 231 rotates forward or reversely, the power battery 3 is driven to move leftwards or rightwards by the left and right screw-nut transmission pair. For example, the left and right screw-nut transmission pair includes left and right screws 232 connected to the left and right adjustment motors 231, and left and right nuts 233 connected to the power battery 3, the left and right nuts 232 being engaged with the left and right screws 233, as shown in fig. 5. Alternatively, the left-right displacement mechanism may take other forms, such as a rack-and-pinion gear pair.

(3) If the car falls into the water, the battery 3 can be automatically moved downwards until the car falls from the car, so that the weight of the car is reduced. So that the passenger has more time to escape the car.
(4) When the tire pressure of one of the tires is high, the power battery 3 can be automatically moved to a position away from the tire to prevent the tire from bursting.
