Description

Automobile front wheel direction aligning indicating disc

Technical Field

The utility model relates to a wheel direction returns positive dial before car belongs to the supplementary teaching device technical field of auttombilism.

Background

How to correctly operate the steering wheel and how to correctly master the rotation degree of the steering wheel so that the automobile moves forward in the correct direction, and how to make the front wheels of the automobile in the positive direction after parking, which is a difficult problem for beginners of automobile driving. Now, the direction state of the front wheels is judged by the position of the steering wheel support, and whether the front wheels are in the positive direction state after parking is judged by the position of the steering wheel support. This may be a minor problem for experienced drivers, but is a poorly mastered matter for beginners. Therefore, the auxiliary device is designed to help the automobile driver to accurately and timely master the direction of the front wheel of the automobile, and has practical significance. When the front wheels of the automobile are in the positive direction, the steering wheel bracket is in the positive direction, which is 0 degrees, and when the steering wheel rotates 360 degrees, the steering wheel bracket is also in the positive direction, but the front wheels have deviated by one angle, that is, when the bracket of the steering wheel is in the positive direction, the front wheels are not necessarily in the positive direction. If the steering wheel needs to be fully turned leftwards, and at the moment, the steering wheel needs to rotate 1.5 circles by 540 degrees; if a full rudder turn is needed to the right, the steering wheel is also needed to be fully turned to the right. For beginners, how many turns or angles of rotation of the steering wheel are not easy to grasp, and at the moment, if the user only judges by feeling or by the steering wheel support, misoperation often occurs. Therefore, it is necessary to provide an auxiliary device to help beginners or drivers to grasp the correct direction of the front wheels.

Disclosure of Invention

The utility model aims at providing a wheel direction returns and just instructs dish before car need not during the driving through the number of turns of beating the steering wheel, or sees the steering wheel support and operate the steering wheel, overcomes beginner or driver new hand and produces the not enough of maloperation easily.

In order to realize foretell purpose, the utility model provides a car front wheel direction returns positive dial, including the appearance like the chassis of heart shape and the panel of cover on the chassis face, be provided with left helicla flute left on the chassis, be provided with right helicla flute right, left helicla flute communicates with each other with right helicla flute, be provided with the smooth pearl in left helical flute and right helicla flute, smooth pearl can be in left helical flute and right helical flute smooth slip, left helicla flute and right helical flute junction are helicla flute lower extreme point, under the car front wheel is in forward state, the smooth pearl is in the lower extreme point of helicla flute.

Adopt above-mentioned measure the utility model discloses, install on car steering wheel, along with the rotation of steering wheel, the helicla flute is also rotatory thereupon, and the smooth pearl produces relative displacement in the helicla flute, through observing the position of smooth pearl in the helicla flute, can know the rotation degree of steering wheel, when the smooth pearl is in the lower extreme point of helicla flute, the front wheel is in the dead ahead upwards promptly. The place ahead wheel direction is not in the positive when can prevent effectively like this that the car from parkking, reaches purpose directly perceived, convenient and accurate just back preceding wheel, simultaneously the utility model discloses small, thickness is thin, can help car beginner and new hand to master the wheel and just technique as early as possible.

The numbering of the above figures illustrates: the steering wheel comprises a chassis 1, a panel 2, a left spiral groove 3, a right spiral groove 4, a sliding ball 5, a spiral groove lower end point 6 and a steering wheel 7.

Detailed Description

As shown in the above drawings, the utility model comprises a chassis 1 and a panel 2, wherein the chassis 1 is made of common plastics, and the panel 2 is made of common plastic transparent material and is stuck on the surface of the chassis 1. The chassis 1 is designed into a heart shape, the transverse diameter is 5-8 cm, the longitudinal diameter is 3.5-6 cm, the thickness is 0.5-1 cm, a left spiral groove 3 and a right spiral groove 4 are arranged on the chassis 1, the arrangement form of the left spiral groove 3 and the right spiral groove 4 is similar to that of a Fibonacci spiral line, and the left spiral groove 3 and the right spiral groove 4 are respectively provided with 1.5 circles according to the rotation number of the automobile steering wheel 7. The left spiral groove 3 is communicated with the right spiral groove 4, the cross section of the left spiral groove 3 is semicircular, the diameter of the left spiral groove 3 is 3-5 mm, a sliding ball 5 is arranged in the right spiral groove 4, the sliding ball 5 is a common metal ball, a purpose-displaying color coating is coated on the sliding ball 5 for the sake of intuition, the diameter of the sliding ball 5 is smaller than the radius of the cross section of the left spiral groove 3 or the right spiral groove 4, therefore, the sliding ball 5 can smoothly slide in the left spiral groove 3 and the right spiral groove 4, and the joint of the left spiral groove 3 and the right spiral groove 4 is the bottom end 6 of the spiral groove. As shown in fig. 3, the utility model discloses must cooperate with car steering wheel 7 to use, fixes the central point at steering wheel 7 through the form of pasting, or produces with steering wheel 7 is whole, rotates along with steering wheel 7's rotation, simultaneously because steering wheel 7 has an angle of inclination with the horizontal plane, so the utility model discloses also there is an angle of inclination, when the direction of car front wheel was towards the dead ahead, sliding ball 5 was in helicla flute bottom 6 department because of the action of gravity. Also because of the gravity, the left helical groove 3 rotates synchronously with the left rotation of the steering wheel 7, when the sliding ball 5 is rotated to the position shown in fig. 4, that is, the steering wheel 7 rotates to the left by one turn, and when the sliding ball 5 is rotated to the position shown in fig. 5, that is, the steering wheel 7 rotates to the left full rudder. The state in which the steering wheel 7 is rotated to the right is the same as the state in which it is rotated to the left, but the direction is opposite, and the description thereof will be omitted.

The utility model discloses a user state is such: as shown in fig. 3, fig. 4 and fig. 5, the utility model discloses must fix at the center of car steering wheel 7, rotate along with the rotation of steering wheel 7, because steering wheel 7 has an angle of inclination with the horizontal plane, the utility model discloses also there is an angle of inclination, because the effect of gravity, when the car front wheel direction was in the dead ahead, smooth pearl 5 was shown in fig. 3 in helicla flute bottom 6 department. During the driving process of the automobile, the steering wheel 7 is a dynamic changing process, fig. 4 and fig. 5 are typical position states of the steering wheel 7, the state shown in fig. 4 is the state of the utility model when the steering wheel 7 rotates leftwards for one week, and the state shown in fig. 5 is the state of the utility model when the steering wheel 7 rotates leftwards for full rudder rotation. When the steering wheel 7 is turned to the right, a situation similar to that of fig. 4 and 5 also exists, but in the opposite direction. In the state of fig. 4 and 5 or the state opposite to the state of fig. 4 and 5, the vehicle is generally in a state of use when turning at a large angle or in a state of use when entering into a side warehouse. The state of fig. 3 is a use state at the time of parking.
