Description

Steering Wheel Steering Angle Indicator

The present invention relates to a steering wheel steering angle indicator of a vehicle, and more particularly, the steering wheel of a vehicle improved in a structure that is thinly configured to be easily mounted on the steering wheel center of an existing vehicle and smoothly rotates without friction and accurately displays an angle. A steering angle indicator.

The steering wheel of the vehicle is an essential device as a mechanism for controlling the driving direction, which is configured to steer by interlocking the front wheels when the driver rotates as intended. In general, the steering wheel of the vehicle is 1.5 turns to the left and right in the case of a passenger car, and the commercial vehicle such as a bus truck is 2.5 turns to make the front wheels at the maximum steering state.

Steering conditions of the front wheels are usually predicted by sensing the steering feelings and the direction of the vehicle's progress, but this is a good driver, and beginners do not know the current condition of the front wheels at the initial stage of departure after parking. In particular, when the driver attempts to escape by using a narrow space between the front and rear vehicles, the driver can see the steering condition of the front wheel from the driver's seat and can steer without contact accident. do.

The known steering angle display method of wheels is to measure the rotation of the steering shaft connected to the steering wheel by using a sensor to calculate it, and then display the steering angle of the wheel as a picture through a display disposed on an instrument panel. It has to be assembled and has a problem that can not be applied to existing vehicles has a difficult problem of practical use.

Another method using gravity action is proposed in Korean Utility Model Publication No. 92-7212. This method restricts the ball or balancer under gravity to move according to a certain trajectory, and allows the plate to be interlocked with the movement of the ball or balancer caused by the rotation of the handle. The movement of the plate body interlocks the direction display panel via the small reduction gear, and the steering state of the front wheel is displayed by the angle value printed on the plate body upper surface through the hole opened in the plate surface.

However, this method has a large number of parts, which is complicated to assemble, and the contact parts between the parts are large, so that the frictional resistance is large. In addition, because the working gravity is large enough to work smoothly, because the bead or balancer must be made more heavy than necessary, the size of the device is larger, and in actual use, the sound plate in the center of the handle should be removed and mounted instead. In general, a switching part for operating the horn is installed at the center of the handle of the vehicle, and these parts are elastically supporting the horn plate, so if the horn plate is removed, the horn of the vehicle becomes useless. In addition, it is difficult to put the ball in the interior of the device, such as a balancer, etc., causing noise during operation, which can cause quiet running.

The present invention provides a steering wheel steering angle indicator of the vehicle improved to a structure that can be made as thin as possible so that any vehicle can be attached to the center of the steering wheel, regardless of the type or type of the vehicle to solve the problems of the prior art described above The purpose is to.

Another object of the present invention is to provide a steering wheel steering angle indicator of a vehicle having a structure capable of displaying an accurate angle by reducing the frequency of failure by reducing friction by using buoyancy.

According to the above object, the present invention has a thin-walled housing in which a fixed pinion having a hollow shaft at its center is integrally formed and sealed by a cover, and a hollow shaft of the fixed pinion is fitted at a central portion thereof. An indicator is provided with a ball to indicate steering of the wheel on one side of the upper surface, a sector member having a first pin buoyancy portion formed therein to form a driven pinion on a part of the outer periphery and retain buoyancy, and a small diameter engaged with the driven pinion at the center thereof. A pinion is formed and the outer circumference is engaged with the fixed pinion and pivots freely in a free state independent of the housing, and a center of the pivoting drive pinion is opened, a shaft hole of the drive pinion, a through hole of the sector member, and the hollow part. Have two axes, each supported by an axis, Attached to a plurality of balancers for balancing, and is added to the plurality of hollow buoyancy forming the window portion and the opposite part for exposing the indicator is constructed as a control display panel ever pictures of buoyancy.

According to the above-described configuration, since the sector member and the reference point display panel are combined in the state of floating under the buoyancy of the liquid in the inside of the housing, the gear interlocking is smoothly displayed.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view showing an example of a device according to the present invention, the fixing pinion 6 having a hollow shaft 4 is integrally formed in the center of the housing 2, the upper portion is formed thin It is sealed by the cover 8, and the sealed inside is filled with water or a non-toxic liquid having a high specific gravity.

The housing 2 and the cover 8 are simply assembled in a snapping manner via a gripper as shown, and in particular, it must be tightly sealed with a sealant so that the liquid filled therein does not leak. The through-hole 12 of the sector member 10 is inserted into the central hollow shaft 4 of the fixed pinion 6 to be rotatably supported, and the drive pinion 14 is free in the outer circumference of the fixed pinion 6. Are matched.

About half of the outer circumference of the sector member 10 is formed with a driven pinion 16 and the rest of the housing 2 has a structure in which the first hollow buoyancy portion 17 is foam-molded. In addition, the plate surface is provided with a colored display unit 18, which is different from other parts in color, so as to indicate the reverse direction of the vehicle.

The colored display unit 18 is displayed as a pair of left and right, between which the indicator 20 is displayed in the radial direction to indicate steering of the wheel. The indicator 20 is very convenient because it can identify the steering state of the wheel even at night when it is displayed as a phosphorescent paint that emits light for a predetermined time when light is irradiated.

The pinion 22 which has a small diameter is located in the center of the drive pinion 14, and this is formed integrally with the drive pinion 14, and the axial hole 24 is opened in the center.

This drive pinion 14 is engaged with the fixed pinion 6, and the pinion 16 having a small diameter is engaged with the driven pinion 16 of the sector member 10. These gear ratios are 1.5 degrees when the steering wheel of the front wheel is displayed in the analogue of the left and right 35 degrees range, the longitudinal reduction ratio between the fixed pinion (6) and the driven pinion (16) is 15.4: 1, 2.5 turns In commercial vehicles such as buses, the ratio is 20: 1.

In the hollow shaft 4 of the fixed pinion 6 and the center shaft hole 24 of the driving pinion 14, a central shaft 28 and an outer circumferential shaft 30 formed on the bottom surface of the reference point display panel 26 are inserted and connected, respectively. do.

The reference point display panel 26 has a window 32 for exposing the indicator 20 of the sector member 10 to the outside, and a reference mark 34 is provided at the center of the window 32. In addition, the angle is numerically described in the upper part of the window 32 in the outward direction based on the reference | standard mark 34. As shown in FIG. In particular, the reference point display panel 26 is a symmetrical position that is located near the window 32 and the outer circumferential axis 30, as shown in FIG. 3. The second hollow buoyancy portion 36 and the third hollow buoyancy portion, as shown in FIG. 3. The foam 38 is foamed and floated inside the housing 2.

A pair of balancers 40 are arranged on both sides of the reference point display panel 26 so that the reference marks 34 always point in a predetermined direction.

The colored display unit 18 described above is displayed to the outside through a pair of backward marks 42a and 42b formed on the reference point display panel 26.

On the other hand, if a protrusion is formed at the inner center of the cover 8 so that the upper center of the upper surface of the reference point display panel 26 is slightly pressed during assembly, no friction occurs between the cover 8 and the reference point display panel 26. It can work more smoothly.

4 is a schematic plan view illustrating an assembled state of a device according to the present invention.

The housing 2 may be bonded to the center of the steering wheel of the existing car through a double-sided tape or the like. In this case, the steering wheel is operated so that the front wheel is parallel to the vehicle body, and the housing 2 is rotated so that the reference of the window 32 is maintained. The mark 34 should be mounted with the indicator 20 coinciding with the indicator 20.

Since the handle is installed to have a substantially predetermined inclination, the housing 2 is also mounted obliquely so that a portion which always faces the driver when operating the handle is placed low. For this reason, the balancer 40 of the reference point display panel 26 balances the reference marks 34 to face the front face by the action of gravity.

When the steering wheel is operated after mounting in this manner, the housing 2 rotates together, and the rotation at this time is indicated by the rotation of the fixed pinion 6 so that the drive pinion 14 is interlocked with each other. As the pinion 22 and the sector member 10 engaged with each other is rotated in coordination, the indicator 20 displays the steering angle of the front wheel while deviating from the reference mark 30 indicating the front of the vehicle at all times. In this case, the sector member 10 is buoyant by the first hollow buoyancy portion 17, and the reference point display panel 26 is buoyant by the second and third hollow buoyancy portions 36 and 38. Because of the excitation state, the frictional force generated at the mutual connection part is reduced to the minimum, and smoothly interlocks.

One of the backward marks 42a and 42b symmetrically opened in this way coincides with the colored display unit 18 formed on the lower sector member 10 and displays it externally. The indicator 20 is directed to the opposite side to the steering direction of the front wheel through the indicator 20 and the reference mark 34 to indicate the backward direction of the vehicle which can be referred to when the vehicle reverses.

As described above, the steering indicator according to the present invention has an advantage that it can be applied without damaging the horn of the vehicle, and can be easily and easily mounted using a double-sided tape or the like.

In addition, as the sector member is buoyant inside the housing attached to the sound recording board, the position movement is smoothly performed, and no noise is generated during traveling.

Furthermore, the steering indicator of the present invention has a low number of parts and is easy to assemble, so that it can be provided at a low production cost. Also, the steering indicator can be applied in various ways depending on whether the handle is inclined. It is based on the fact that the housing can be made extremely thin.
