Abstract
The utility model provides a pressure sensing device for keeping balance, which comprises a shell, a ball-shaped balance stone and a plurality of contact rods, wherein the bottom of the shell is provided with the ball-shaped balance stone and the plurality of contact rods, the contact rods are arranged around the balance stone, and one end of each contact rod, which is near to the balance stone, is provided with a contact point; the contact rods are internally provided with a plurality of pressure sensors; the pressure sensors are connected with a receiving device and an actuating mechanism; and the pressure sensors are piezoresistors. In use, when the shell is slantwise and after the pressure sensing contact points around the balance stone are pressed, an electric signal is transferred to the receiving device and to the action-controlled actuating mechanism to be ministered or adjusted, and the pressures of the contact points with different directions are adjusted by a balance ball under the action of the gravity and the other acceleration forces, so that the shell can be kept to be balanced. The pressure sensing device has the advantages of being wide in application range, exact in measuring result, fast in signal transmitting speed, easy to manufacture, low in cost, small in wearing, strong in stability, easy to popularize, good in market prospect.
Description
Technical field the utility model relates to a kind of device that keeps balance, especially a kind of pressure of sensing all directions, and can be scheduled to adjust the pressure sensor device that keeps balance.
Background technology is well-known, pressure transducer is a kind of sensor the most commonly used in the industrial practice, it is widely used in various industrial automatic control environment, relate to water conservancy and hydropower, railway traffic, intelligent building, the production automatic control, Aero-Space, military project, petrochemical industry, oil well, electric power, boats and ships, lathe, numerous industries such as pipeline, and our normally used pressure transducer mainly contains strain gauge pressure sensor, ceramic pressure sensor, diffusion silicon pressure sensor and piezo-electric pressure sensor etc., the drawback that these pressure transducers exist is to operate complexity, price is more expensive, and pressure that can not the sensing all directions, and adjust the maintenance balance, use that can not Manchus needs.
The summary of the invention the purpose of this utility model is to provide a kind of pressure sensor device that keeps balance, to satisfy people's use needs.
The utility model comprises housing, spherical statolith and feeler lever, is provided with statolith and feeler lever in the bottom of housing, and feeler lever is many, and is positioned at the periphery of statolith, is provided with the contact at feeler lever near an end of statolith; Inside at feeler lever is provided with pressure transducer; Pressure transducer is connected with topworks with receiving trap; Pressure transducer is a voltage dependent resistor (VDR).
After adopting said structure, during use, when the housing run-off the straight, behind the pressure sensing contact pressurized around the statolith, form with electric signal passes on the receiving device, pass in the topworks of control action again and monitor or adjust, pressure is adjusted in balance ball contact to different directions under the effect of gravity and other acceleration force then, can make housing keep balance.
The utility model has the advantages that: have wide range of applications, the power that causes with gravity and acceleration is Basic Controlling Conditions, and measurement result is accurate, and the signal transmission speed is fast; Be not subjected to the external condition cross interference, measured single and conduct unidirectional, be easy to make, with low cost, attrition is little, stability is strong, popularization is easy, has good market outlook.
Description of drawings Fig. 1 is that A under the utility model equilibrium state is to constructed profile.
Fig. 2 is that A under the utility model non-equilibrium state is to constructed profile.
Embodiment is in the synoptic diagram of the pressure sensor device of Fig. 1, maintenance balance shown in Figure 2, comprise housing 1, spherical statolith 2 and feeler lever 3, be provided with statolith and feeler lever in the bottom of housing, and feeler lever is many, and be positioned at the periphery of statolith, be provided with contact 4 at feeler lever near an end of statolith; Be provided with pressure transducer 5 in the inside of feeler lever; Pressure transducer is connected with topworks 7 with receiving trap 6; Pressure transducer is a voltage dependent resistor (VDR).When keeping balance to use, be the most basic application mode, just in the normal operation process, can compensate automatically unbalanced variation.For example: in robot makes, add this device, can make robot be difficult for falling, basic balanced structure has been arranged, be beneficial to the research and development of imitation human body intelligent function, also help guaranteeing the safety and the quality of robot; When navigation is used, use also very extensively, automobile, train, steamer, aircraft can be applied to the present invention, have given the ability of vehicles intelligent automatic runnings, also provide reference for unmanned.Can be at signal Processing center editor's route, pressure sensor device can be repaid real-time travel conditions, and this device just can serve as navigation and supervising device simultaneously; When the production automatic control was used, some parts or petty commodities manufacturing realized mechanization substantially at present, but the poor stability of some machine is subjected to the external interference factor affecting big, substandard products and rejection rate height.At these the present invention is installed mechanically its accuracy is improved greatly, save the cost savings resource.
