Electronic speed odometer has many advantages,so it gradually replaces the mechanical speed odometer driven by the soft shaft. But at present,the electronic speed odom eter still has a large room for improvement. Now ZHAOWEI micro gearbox can better control the instrument,beats of the stepping motor during the use, the jitter of the pointer and reduce the noise problem during the use of the product.
With the wide application of the latest digital electronic systems and computer technology in automotive engines and vehicle control systems, manufacturers are actively promoting the development and production of electronic display systems.In the mass production process of automobile instruments, new problems have also appeared, that is, the beating of the stepping motor during the use, the jitter of the pointer and the noise problem during the use of the product.
Electronic speed odometer and mechanical speed odometer
Modern car is moving at a high speed, and the odometer driven by a soft shaft is facing unprecedented challenges. The soft shaft rotates at high speed, The hysteresis of its movement is limited by the alternating stress of the steel wire.The high-speed vehicle often causes the fatigue of the soft shaft of the steel wire to break, thus invalidating the function of the odometer. Therefore, more electronic speedometers are now used.Electronic speed odometer has the same functions as mechanical speed odometer,but their principles are fundamentally different.The electronic speedometer is driven by a stepper motor to drive a mechanical mileage recording mechanism (counter) and the stepper motor is controlled by the output signal of the Hall sensor mounted in the gearbox.
The stepper motor is driven by a special integrated circuit, and the amount of rotation of the stepper motor is in a certain speed ratio relationship with the amount of rotation of the output shaft of the transmission.Therefore,electronic speed odometer has many advantages,so it gradually replaces the mechanical speed odometer driven by the soft shaft.
The stepper motor rotates a step angle every time it receives a driving pulse signal,driving micro gear to rotate..so the stepper motor and micro gears must have high-precision,small volume,large torque,stable output, and a wide range of reduction ratios to meet the different types of Instrument panel or electronic speed odometer.and our ZHAOWEI gear motor meets greatly these needs.

The head-up display shows important information such as driving speed, temperature, etc. on the holographic half mirror on the windshield so that the driver can see important information without having to bow his head.The essence of the heads-up display is to increase the safety of people’s driving. However, some head-up displays on the market also have some bugs. In driving, the head-up display angle is incorrect. In normal sitting position, the information displayed on the display screen cannot be seen.The display screen must be pushed forward to a angle then you can see information. All of these will the safety of driving.
ZHAOWEI gearbox solutions for HUD
For the large-angle intelligent opening and closing requirements of the HUD, we have developed a gearbox solution for HUD flipping. By analyzing the structure of the flip-up display of the head-up display, the gear reversing device can form two sets of transmission paths by the reversing action of the reversing mechanism on the bracket of the display screen, one of which is an input shaft, a reversing mechanism ,a forward gear train,and the transmission system formed by the output gear, the second is the transmission system composed of the input shaft, the reversing mechanism, the reverse gear train and the output gear.When the forward gear train participates in the transmission, the output gear rotates forward, when the reverse gear train participates in the transmission, the output gear is reversed, so that the change of the output gear steering can be realized by the conversion of the above two sets of transmission routes, so as to avoid damage to the gear caused by the excessive load, and stably solve the angle adjustment problem of the head-up display during the driving process, improving the behavior of safe driving.
In order to meet the demand of small volume and large torque and meet the transmission torque of the head-up display with easy and intelligent rotation, we have developed and designed a multi-layer convertible transmission ratio mechanism.The product has two-stage, three-stage and four-stage transmission changes,so the reduction ratio can be changed and and the input speed and torque of the gearbox can be adjusted according to the design requirements of the head-up display.
Growing market demand
With the continuous development of intelligent driving technology, more and more information is needed to judge and remind for a car. Today’s dashboards obviously cannot meet these needs. It is inevitable to display driving information and road information on the windshield. trend. Nowadays more and more manufacturers have invested in this field. The importance of HUD is self-evident. We need a higher specification of HUD standard to promote the product.The head-up display flip gearbox produced by ZHAOWEI can be adapted to the head-up display with the ever-changing market demand, and we can provide HUD and other automotive parts transmission gearboxes according to customer needs.
So a cool head-up display
