Description

Technical Field

[0001] The present invention relates to the field of mechanical equipment, and in particular to a device that can adjust the center of gravity position and a method of use thereof. Background Art

[0002] Many mechanical equipment with integral motion, hereinafter referred to as equipment, including but not limited to engineering machinery and transport vehicles, have very high requirements for stability. However, their stability will decrease when driving on a slope, turning, accelerating or decelerating. If the above situations occur at the same time, the risk of equipment instability will be greatly increased. At present, we can only consider all risk situations during design and reserve sufficient safety margins to ensure the safe use of equipment, but this will impose many constraints on product design and make many functions unable to be fully utilized.

[0003] Therefore, it is necessary to develop a new device that can adjust the center of gravity position so that when the above-mentioned stability of the equipment decreases, the center of gravity position of the device can be automatically adjusted, thereby improving the overall stability of the equipment. Summary of the invention

[0004] Purpose of the invention: In view of the shortcomings and defects of the prior art, the present invention provides a device capable of adjusting the position of the center of gravity and a method of using the device, so that when the above-mentioned stability reduction of the equipment occurs, the position of the center of gravity can be automatically adjusted by moving the floating body in the opposite direction of the synthetic acceleration direction, thereby improving the overall stability of the equipment and reducing the risk of equipment instability.

[0005] Technical solution: The present invention is a device capable of adjusting the center of gravity, characterized in that it includes an outer shell, a base liquid and a floating body, wherein a certain amount of base liquid and a floating body are contained inside the closed outer shell, and the base liquid provides buoyancy for the floating body; when the device is subjected to a certain acceleration, the internal base liquid provides the floating body with a floating acceleration opposite to the acceleration direction, and the floating body moves to the direction opposite to the acceleration, thereby adjusting the center of gravity of the device.

[0006] The shape of the shell is a rectangular body, a cylinder, a sphere or a special shape.

[0007] The base liquid is water or kerosene.

[0008] The floating body has a hollow sphere, a hollow cylinder or a special shape.

[0009] The number of floating bodies is a single, two or more.

[0010] The total mass of the floating body is greater than the total mass of the base liquid.

[0011] The total resistance of the floating body is smaller than the buoyancy of the base liquid immersed in the floating body on the floating body.

[0012] The method for using the device capable of adjusting the center of gravity position of the present invention is characterized in that: when the floating body is in a stationary base liquid, under the influence of gravity, the deeper it is in the direction of gravitational acceleration, the greater the pressure it is subjected to. Therefore, due to the different pressure differences between the upper and lower surfaces of the floating body in the base liquid, and the pressure below being greater than the pressure above, a buoyancy in the opposite direction to the gravitational acceleration is formed.

[0013] When the device is in overall motion and there is inertial acceleration, the direction of buoyancy and the direction of gravitational acceleration do not always coincide with each other. Therefore, the direction of buoyancy at this time is opposite to the direction of the synthesized acceleration, that is, the direction of the synthesis of gravitational acceleration and inertial acceleration.

[0015] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: When the above-mentioned stability reduction occurs in the equipment, the present invention can automatically adjust the center of gravity position by moving the floating body in the opposite direction of the synthetic acceleration direction, thereby improving the overall stability of the equipment and reducing the risk of equipment instability.

[0021] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] The device of the present invention that can adjust the center of gravity position includes an outer shell 1, a base liquid 2 and a floating body 3. A certain amount of base liquid 2 and the floating body 3 are contained inside the closed outer shell 1, and the base liquid 2 provides buoyancy for the floating body 3. When the device is subjected to a certain acceleration, the base liquid 2 inside provides a floating acceleration opposite to the acceleration direction to the floating body 3, and the floating body 3 moves to the direction opposite to the acceleration, thereby adjusting the center of gravity position of the device.

[0023] The shell 1 of the present invention is in the shape of a cuboid, a cylinder, a sphere or other special shapes; it provides a closed environment and is easy to assemble. The base liquid 2 is water, kerosene or other safe liquids. The floating body 3 is in the shape of a hollow sphere, a hollow cylinder or other shapes. The number of the floating bodies 3 is one, two or more than two.

[0024] The total mass of the floating body 3 of the present invention is greater than the total mass of the base liquid 2. The total resistance of the floating body 3 (including the sum of gravity and other resistances) is less than the buoyancy of the base liquid 2 submerging the floating body 3 on the floating body 3. After satisfying both conditions, the more obvious the change in the position of the floating body has on the position of the overall center of gravity of the device, the better the effect.

[0025] The floating body 3 is in the static base liquid 2. Under the influence of gravity, the deeper it goes in the direction of gravitational acceleration, the greater the pressure it is subjected to. Therefore, due to the different pressure differences between the upper and lower surfaces of the floating body 3 in the base liquid 2, and the pressure below is greater than the pressure above, a buoyancy in the opposite direction of gravitational acceleration is formed.

[0026] When the device moves as a whole and there is inertial acceleration (similar to the case of gravity alone, but with different acceleration synthesis), the direction of buoyancy and gravity acceleration do not always coincide, so the direction of buoyancy at this time is opposite to the synthesized acceleration, that is, the direction of gravity acceleration and inertial acceleration synthesis. The device can also be combined with other structures, as long as the above conditions are met, it can achieve the corresponding effect.

[0027] Embodiment 1:

[0028] like Figure 2 and 4 , the device is placed horizontally or tilted, and when it is stationary, the acceleration of gravity is vertically downward, and the buoyancy is upward, then the floating body is on the upper part of the device; if this device is horizontally fixed on a vehicle, when the vehicle is on a slope, the center of gravity of the device moves toward the direction of the high slope, causing the center of gravity of the vehicle to move in that direction, then its stability is enhanced.

[0029] Embodiment 2:

[0030] like Figure 3 When the device is placed horizontally and has a horizontal acceleration to the right, the resultant acceleration is to the lower right, and the buoyancy is to the upper direction, then the floating body is in the upper left part of the device; this device is fixed horizontally on a vehicle, and when the vehicle decelerates on a horizontal road, the inertial acceleration is forward, the gravity acceleration is downward, and the resultant acceleration is to the lower right, then the floating body is in the upper left part of the device, and the center of gravity of the device moves to the left, causing the center of gravity of the vehicle to move in this direction as well, and its stability is enhanced.

[0031] The present invention allows the device to automatically adjust its center of gravity by moving the floating body in the opposite direction of the synthetic acceleration direction when the device experiences the above-mentioned stability reduction, thereby improving the overall stability of the device and reducing the risk of device instability.
