Embodiment 1

[0020] like figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, the supporting structure of a DIG automobile instrument rotary dial of the present invention includes an instrument base 1 and a dial 3, and the dial 3 is arranged on the instrument base 1, wherein the dial 3 is circular, There is a gap between the plane of the dial 3 and the instrument base 1. The instrument base 1 is provided with two pulleys 62 and two pulleys 72. The pulleys 62 and the pulleys 72 are evenly distributed along the circumferential direction and are respectively connected to the outer circle of the dial 3. Tangent.

[0021] Further, teeth 2 are continuously provided on the outer circumference of the dial 3 .

[0022] Further, the instrument base 1 is provided with a motor (not shown in the figure), the output shaft of the motor is provided with a driving gear (not shown in the figure), and the driving gear and the dial 3 meshes.

[0023] Further, two pulley brackets 6 and tw...

Abstract

The invention discloses a support structure for a DIG (Display In Gauge) automobile instrument rotational dial. The support structure comprises an instrument seat and a dial; the dial is circular; a gap is arranged between the dial surface and the instrument seat; at least three pulleys are arranged on the instrument seat; and the pulleys are uniformly distributed along the circumferential direction and tangential to the excircle of the dial. Teeth are continuously arranged on the outer circumference of the dial. Pulley support frames with the same number as the pulleys are fixedly arranged on the instrument seat, and the pulleys are respectively arranged in one pulley support frame through pulley shafts. At least one pulley shaft is connected with the pulley support frame, on which the pulley shaft is, through an elastic floating mechanism. The pulleys are in point contact with the excircle of the dial, so that the frictional resistance is less, therefore the load driven by a motor can be reduced, and the reliability of a motion mechanism is increased; the elastic floating mechanism offsets at least one pulley to the circle centre direction of the dial, so that the stable rotation of the dial can be supported, therefore the gap and jitter between the dial and each pulley in the rotation process are eliminated. A pointer is fixed, and a display screen is fixedly arranged in the instrument seat and can be observed through a central window of the dial.

Description

Technical field: [0001] The invention relates to the field of physics, in particular to an automobile instrument, in particular to a supporting structure for a rotating dial of a DIG automobile instrument. Background technique: [0002] With the digital development of automotive electronics, DIG (Display In Gauge) technology is widely used in automotive instrumentation. DIG technology sets the display screen in the car dashboard, which can display many important driving information, safety information and entertainment information in the car in digital form. The display screen is set in the middle of the car's dashboard and maximizes the digital display, which changes the way the conventional gauge needle rotates in the middle of the gauge head. In the prior art, the DIG instrument puts the display screen in the middle of the dial, the pointer is fixed, and the dial rotates. The movement structure of the dial includes a motor arranged on the outside of the dial, and the mot...
