FIG. 2 is a schematic sectional view of the arcuate roller groove.
Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed embodiments and the specific operation processes are provided, but the protection scope of the present invention is not limited to the present embodiment.
As shown in fig. 1 to 2, the embodiment provides a mobile device anti-falling device, which includes a device body 1 and an anti-falling device disposed in the device body, where the anti-falling device includes an arc rolling groove 2, a magnetic member 3, a hall sensor 4, and a pressure sensor 5, horizontal positions of two ends of the arc rolling groove 2 are higher than a horizontal position of a middle portion of the arc rolling groove, the magnetic member 3 is disposed in the arc rolling groove 2, two sides of the arc rolling groove 2 extend in a direction approaching each other to form a blocking portion 6, and the magnetic member 3 can roll along the arc rolling groove 2; the Hall sensor 4 is arranged at the lower side of the arc-shaped rolling groove 2, and the pressure sensors 5 are arranged at two ends of the arc-shaped rolling groove 2; the blocking part 6 is used for blocking the magnetic part 3 from being separated from the arc-shaped rolling groove 2.
Preferably, in this embodiment, the magnetic member is a magnetic ball.
Further, prevent falling device internally mounted and have the circuit mainboard, pressure sensor 5 communication connection the circuit mainboard.
Further, the circuit main board is in communication connection with the hall sensor 4.
The magnetic part 3 can be induced with the Hall sensor 4, the Hall sensor 4 generates a voltage value, the voltage generated in the Hall sensor 4 changes along with the change of the magnetic field intensity, and the stronger the magnetic field is, the higher the voltage is, the weaker the magnetic field is, and the lower the voltage is; when the equipment body 1 is horizontally placed, the magnetic part 3 is positioned at the lowest position in the middle of the arc-shaped rolling groove 2, and the magnetic field intensity of the magnetic part 3 has a large influence on the Hall sensor 4, so that the voltage value is large; when the device body 1 inclines, the magnetic pieces 3 roll to the two ends of the arc-shaped rolling groove and are far away from the Hall sensor 4, the influence of the magnetic field intensity of the magnetic pieces 3 on the Hall sensor 4 is reduced, and therefore the voltage value is reduced.
The Hall sensor presets a voltage value, when a voltage value signal formed by the Hall sensor and the magnetic part in an induction mode is smaller than the preset voltage value, the Hall sensor 4 sends a feedback signal to the circuit main board, the circuit main board receives the feedback signal, and then the circuit main board further receives a signal transmitted by the pressure sensor 5.
When the equipment body is horizontally placed, the magnetic part is located at the lowest position of the arc-shaped rolling groove and is far away from the pressure sensor, and the magnetic part has small influence on the pressure sensor, so that the pressure value detected by the pressure sensor is small; when the equipment body inclines, the magnetic part rolls to the both ends of arc rolling groove, the magnetic part is right pressure sensor has, the magnetic part influences the grow to pressure sensor, therefore the pressure value grow that pressure sensor detected.
The pressure sensor is preset with a pressure value, when a pressure value signal formed by the magnetic part to the pressure sensor is smaller than a preset voltage value, the pressure sensor sends a feedback signal to the circuit main board, and the circuit main board receives the feedback signal.
In this embodiment, a power module and an acousto-optic module are installed inside the anti-falling device, the power module is connected to the circuit board, and the acousto-optic module is connected to the circuit board. The power supply module supplies power to the circuit main board, and the circuit main board supplies power to the Hall sensor and the pressure sensor.
When the pressure value signal is larger than the preset pressure value, the circuit main board controls the acousto-optic module to make sound and light to warn a user.
The working principle of the anti-falling device of the mobile equipment is as follows:
the anti-falling device is arranged on the mobile equipment, when the mobile equipment is horizontally placed, the magnetic part is located at the lowest position in the middle of the arc-shaped rolling groove, the magnetic part is closer to the Hall sensor and farther from the pressure sensor, the voltage value of the Hall sensor is not smaller than a preset voltage value, the pressure value of the pressure sensor does not exceed the preset pressure value, and the circuit main board judges the state of the mobile equipment to be a normal state;
when the mobile device is the slope, the magnetic part slides to the both ends of arc rolling slot from the middle lowest of arc rolling slot, and the magnetic part distance this moment hall sensor is far away, and the magnetic part is right pressure sensor has pressure, hall sensor's voltage value signal is less than predetermined voltage value, and hall sensor transmits feedback signal to circuit board, circuit board further receives the feedback signal of pressure sensor transmission, pressure sensor's pressure value signal surpasss predetermined pressure value, and circuit board judges the state of being about to drop to the mobile device's state, and the reputation module of circuit board controlgear body sends sound and light scintillation to warn the user.
The device determines the posture of the current equipment through double detection of the Hall sensor and the pressure sensor, and has strong reliability.
Various corresponding changes and modifications can be made by those skilled in the art according to the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
