Abstract
The utility model discloses a built-in tire pressure control device which comprises an inner tire and a wheel hub. The built-in tire pressure control device is improved that a micro air pump is arranged on the inner side face of the wheel hub, and an air outlet end of the micro air pump is communicated with the inner tire through a first electrical control one-way valve. The inner tire is provided with an exhaust port which is provided with a second electrical control one-way valve. The inner side of the inner tire is communicated with external environment through the second electrical control one-way valve. The micro air pump, the first electrical control one-way valve and the second electrical control one-way valve are connected electrically with a singlechip microcomputer. The singlechip microcomputer is in communication connection with a vehicle-mounted ECU (Electronic Control Unit). The inner tire is internally provided with a sensor which detects the inner air pressure and temperature data of the inner tire. The sensor is in communication connection with the singlechip microcomputer.
Description
Technical field
The utility model relates to a kind of car-mounted device, relates in particular to a kind of built-in tire pressure control setup.
Background technology
The inner tube of a tyre is the vitals on the vehicle, and the pressure size in the inner tube of a tyre has material impact to the adherence properties of tire, road-holding property and the load-carrying ability of vehicle; In the prior art, can't automatically control the internal pressure of the inner tube of a tyre, can only filling, exitting and regulate tire pressure by the manual operation inner tube of a tyre; The factor that affects tire pressure is varied, such as temperature, load-carrying, the speed of a motor vehicle, road conditions etc., therefore, if make the pressure in the inner tube of a tyre be in preferably state, should regulate in real time pressure in the inner tube of a tyre according to many external circumstances, so just can make vehicle obtain preferably rideability.
The utility model content
For the problem in the background technology, the utility model proposes a kind of built-in tire pressure control setup, comprise the inner tube of a tyre and wheel hub, its improvement is: the medial surface at wheel hub is provided with micro air pump, is communicated with by the first automatically controlled Non-return air valve between the outlet side of micro air pump and the inner tube of a tyre; Be provided with exhausr port on the inner tube of a tyre, exhaust ports is provided with the second automatically controlled Non-return air valve, is communicated with by the second automatically controlled Non-return air valve between inner tube of a tyre inside and the external environment; Micro air pump, the first automatically controlled Non-return air valve and the second automatically controlled Non-return air valve three are electrically connected with a micro controller system; Micro controller system and vehicle-mounted ECU communication connection; Inner tube of a tyre inside is provided with sensor, and sensor detects air pressure and the temperature data of inner tube of a tyre inside; Sensor is connected with single chip communication.
Useful technique effect of the present utility model is: when interior tire pressure is excessive, can automatically unload press operation to the inner tube of a tyre, avoid blowing out; When interior tire pressure is too small, can automatically carry out blower operations to the inner tube of a tyre, make vehicle obtain preferably adherence properties, improve the safety of Vehicle Driving Cycle.
Description of drawings
Fig. 1, structural representation of the present utility model.
The specific embodiment
A kind of built-in tire pressure control setup comprises the inner tube of a tyre 1 and wheel hub 2, and its improvement is: the medial surface at wheel hub 2 is provided with micro air pump 3, is communicated with by the first automatically controlled Non-return air valve 4 between the outlet side of micro air pump 3 and the inner tube of a tyre 1; Be provided with exhausr port on the inner tube of a tyre 1, exhaust ports is provided with the second automatically controlled Non-return air valve 5, is communicated with by the second automatically controlled Non-return air valve 5 between the inner tube of a tyre 1 inside and the external environment; Micro air pump 3, the first automatically controlled Non-return air valve 4 and the second automatically controlled Non-return air valve 5 threes are electrically connected with a micro controller system 6; Micro controller system 6 and vehicle-mounted ECU communication connection; The inner tube of a tyre 1 inside is provided with sensor, and sensor detects air pressure and the temperature data of the inner tube of a tyre 1 inside; Sensor and micro controller system 6 communication connections.
Principle of work of the present utility model is: when device was not worked, micro air pump 3, the first automatically controlled Non-return air valve 4 and the second automatically controlled Non-return air valve 5 all were in closed condition, and the inner tube of a tyre 1 inside is in closed state; Micro controller system 6 is by temperature, pressure data (referred to as real time data) in the sensor Real-time Collection inner tube of a tyre 1, simultaneously micro controller system 6 also obtains real-time ambient temperature, barometric information by ECU, and presets the inner tube of a tyre 1 internal temperature under the ideal conditions and the mapping table (being called for short corresponding table) of pressure in the micro controller system 6; When micro controller system 6 knows that the gentle pressure of ambient temperature changes, micro controller system 6 is compared the data that sensor collects with corresponding table, if the force value of the correspondence in the correspondence table of the temperature value in the real time data is not identical with the force value of actual measurement, then micro controller system 6 carries out corresponding actions with regard to needs control the first automatically controlled Non-return air valve 4 and the second automatically controlled Non-return air valve 5: when observed pressure is higher than setting pressure, micro controller system 6 is just controlled the second automatically controlled Non-return air valve 5 and is opened, and the inner tube of a tyre 1 is unloaded press operation; When observed pressure was lower than setting pressure, micro controller system 6 was just controlled micro air pump 3 and is started, and opens simultaneously the first automatically controlled Non-return air valve 4, and the inner tube of a tyre 1 is carried out boost operations; Concrete fill, discharge quantity, can calculate according to the power of micro air pump 3 and the unit time flow of the first automatically controlled Non-return air valve 4 and the second automatically controlled Non-return air valve 5, finally control the filling of the inner tube of a tyre 1, discharge quantity by the work duration of control micro air pump 3, the first automatically controlled Non-return air valve 4 and the second automatically controlled Non-return air valve 5.
