Problems solved by technology

This will cause inconvenience to passing vehicles and is not conducive to the maintenance of the wheel system.
And because the steering wheel is locked when the car is turned off, the driver must restart the engine and then return the steering wheel.

Embodiment 1

[0030] figure 1 Shown is the first embodiment of the spiral wall steering wheel indicator, wherein the indicator includes a housing, the housing includes a cover-shaped base shell 1 and a Figure 5 The transparent panel 4 that covers the base shell 1 is shown; in the oblate cylindrical cavity inside the shell, a continuous spiral wall 2 is formed; the two sides of the spiral wall 2 are covered by the cavity The bottom surface 11, the side 12 and the panel 4 are airtightly sandwiched; the spiral path of the spiral wall 2 takes the central axis of the cavity as the axis of revolution, and the end of the outermost circle ends at the side 12 of the cavity; In the spiral channel formed between the bottom surface 11 of the cavity, the spiral wall 2 and the panel 4, liquid is sealed and an air bubble 3 remains.

[0031] In Embodiment 1, the number of spiral turns of the spiral wall 2 is 4 turns, and the side walls of each turn of the spiral wall 2 are equidistant; the calculation of...

Embodiment 2

[0038] Figure 4 Shown is the second embodiment of the spiral wall steering wheel indicator, which differs from the first embodiment in that: a small cylinder 5 coaxial with the central axis is formed at the central axis of the cavity, so The spiral wall 2 starts to radiate outward from the surface of the small cylinder 5 . The advantage of this design point is that: the inner end of the spiral passage is closed by the small cylinder 5, so that after the air bubbles 3 move to the inner end of the spiral passage, it is difficult for the air bubbles 3 to transfer to the outer layer when vibrating violently; and figure 1In the first embodiment shown, when the bubble 3 moves to the inner side of point S, in case of severe vibration, the bubble 3 can easily bypass point S and run to the spiral channel layer between point S and point M.

Abstract

The utility model provides a pedestal wall-type steering wheel indicator. The indicator comprises a housing. The housing comprises a cover-shaped base shell and a transparent panel capping the base shell. A continuous spiral wall is made in a flat cylindrical cavity in the housing. Two side planes of a spiral wall are clamped by the bottom face of the cavity, the side of the cavity and the panel in an airtight manner. A spiral path of the spiral wall takes the central shaft of the cavity as a whirling shaft. The tail end of an outmost ring ends on the side of the cavity. Liquid is sealed and a bubble is left in spiral channels formed among the bottom face of the cavity, the spiral wall and the panel. The indicator can be easily arranged on a steering wheel of a mechanical revolving mechanism to indicate the current rotation angles of the steering steel, so it is easy for people to park a car.

Description

[0001] technical field [0002] The invention relates to the field of mechanical steering mechanism accessories, in particular to a steering wheel indicator. [0003] Background technique [0004] In the two-way steering mechanism, power steering is usually performed through the steering wheel. In general, the steering wheel can be turned left (counterclockwise) or right (clockwise) through N circles. Therefore, when the operator is not paying attention, it is easy to forget The current number of turns of the steering wheel. [0005] The above-mentioned problems are particularly prominent in the parking process of the car, especially in the processes such as side parking. In the process of side parking, the driver often needs to turn the steering wheel continuously; under normal circumstances, it needs to turn the steering wheel 3 to 4 times to turn the wheel from the extreme position of left deviation to the extreme position of right deviation; , because the attention is...
