Abstract
The utility model discloses an electric sensing speed odometer, comprising a sensor and an indicator. The indicator is arranged in the vehicles to display the vehicle mileage and speed per hour; the sensor is connected with the vehicle gearbox and changes the mileage and the speed per hour into the electric signal; the sensor is connected with the indicator through a wire. The electric sensing speed odometer is convenient to install and can save the driving flexible tube and improve the indicating accuracy.
Description
The utility model is the automobile Displaying Meter.
Existing automobile odometer, the mode that adopts mechanical drive to show connects transmission with flexible axle.When connecting transmission with flexible axle, its installation site is subjected to the restriction of flexible axle length and flexibility.Different vehicles requires to have the flexible axle of corresponding specification, uses inconvenience, and because the flexible and friction of flexible axle in flexible pipe, and the wearing and tearing that connect square shaft, the indication stability of instrument is affected, flexible axle is also fragile, automobile is when reversing, and the mileage counting also returns down, and counting has error.
The utility model provides a kind of fax sense speedometer, and gearbox gear is between the car internal indicator, without the flexible axle transmission, reduced mechanical drive wearing and tearing and loss, improved the accuracy of instrument and adaptability is installed, when reversing, the mileage counter counting forward helps accurate counting.
The utility model is made up of sensor and indicator etc.Sensor is by connector (1), nut (2), metallic sheath (3), web joint (4), small generators (5), worm screw (6), worm gear (7), dead ring (8), conducting strip (9,11), back up pad (10), binding post compositions such as (12,13,14).Above component-assembled is in a housing.Indicator is by counter and magneto-electric speed per hour device, binding post compositions such as (15,16,17,18).Counter supports tooth (20) by great wheel (19), extension spring (21), and suction disc (22), relay (23), digit wheel (24) waits composition.Counter and magneto-electric speed per hour device are assembled in the housing.Sensor is connected on the automobile gearbox, converts the speed of a motor vehicle to electric signal, flows to the automobile internal indicator by lead, shows mileage and speed per hour.It is simple in structure, and is easy to use, and cost is low, and sensor connects wheel box than much smaller with flexible axle connection wheel box power consumption originally.

Fig. 2 is the indicator synoptic diagram
Below in conjunction with accompanying drawing this instrument is elaborated:
Connector in the sensor (1), be connected on the automobile gearbox, during running car, gearbox gear drives worm screw (6) by connector (1) and small generators (5) rotor rotates, form electromotive force after small generators (5) rotor rotation, be wired in the indicator in the magneto-electric speed per hour device (25) the display automobile speed per hour.Worm screw (6) is rotated the back and drives worm gear (7) rotation, be close to a dead ring (8) on the worm gear, worm gear and dead ring rotate simultaneously, one conducting strip (9) is arranged on the dead ring (8), conducting strip (9) inner end is near back up pad (10), lead to the output terminal that underbody car is linked automobile storage battery by web joint (4), conducting strip (11) is pressed against on the dead ring (8), and by binding post (12,15) and lead be connected to an end of relay (23) in the indicator, relay (23) other end is received another output terminal of automobile storage battery by binding post (16), when dead ring (8) rotates, make conducting strip (9) and conducting strip (11) when contacting, relay (23) energising, inhaling moving suction disc (22) drive support tooth (20) moves down, when dead ring (8) rotates, make conducting strip (9,11) after mutual the disengaging, relay (23) outage, extension spring (21) retracts support tooth (20), support tooth (20) promotes great wheel (19) and rotates a tooth, makes digit wheel (24) carry, the display automobile mileage.During reversing automobile, worm gear (7) dead ring (8) reversing, the conducting strip (9) on the dead ring (8) contacts with conducting strip (11), makes relay (23) energising, inhales moving suction disc (22) and makes digit wheel (24) carry, and digit wheel (24) is still the forward carry.
Claims (3)
1, a kind of fax sense speedometer: form by sensor and indicator.It is characterized in that sensor is connected on the automobile gearbox, indicator is installed in the automobile, connects with lead between sensor and the indicator.
2, small generators (5) is arranged, worm screw (6), worm gear (7), dead ring (8), conducting strip (9,11) in the speedometer of stipulating by claim 1, the sensor.
3, by the speedometer of claim 1 regulation, relay (23) is arranged, magneto-electric speed per hour device (25) in the indicator.
