Abstract

PURPOSE:To improve the contrast of a display by providing an I-section steering handle with a vertical wall area having a wide central section and the both ends tapered and curved toward the driver, and providing a liquid crystal type display on the notched window in said vertical wall area. CONSTITUTION:A steering handle 13 has an I-section consisting of top and bottom surfaces 13a and 13b, and a vertical wall 13c. The vertical wall 13c is formed in such a way that the central section 14 is wide and nearly in square shape while the both side sections 15 are curved toward the driver with tapering ends. The central section 14 is provided with a notched window 13d, in which a liquid crystal type meter display 17 is fitted. The display 17 comprises a guard plate 17a, liquid crystal cells 17b and a translucent screen 17c, and is formed so as to have a slightly concaved surface on the side of the driver. The display 17 is connected to an electric circuit through wiring 17d. Accordingly, the contrast of display is improved because the display 17 is easy to see under the light in the forward direction and the segment appears floatingly while a flat surface reflection is prevented when it is seen against the light.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid crystal meter display for a motorcycle that has improved visibility and a modern feel.

The liquid crystal meter display matches modern sensibilities, consumes little power, and has the advantage of being able to install the display in any location. It is starting to be widely adopted. Therefore, in a conventional liquid crystal meter installed in a motorcycle, a meter case 3 is attached to a top bridge 5 on the top of a front fork 4 in front of a steering handle 2 of a motorcycle 1, as shown in Figure 1, for example. A liquid crystal meter display section 6 is provided on the front surface of 3.

A screen 7 made of a glass plate or a transparent plastic plate for night illumination and a lighting screen 8 are installed on the back side of the liquid crystal meter display section 6, and an electric circuit s9 is housed inside the meter case 3. It is electrically connected to the liquid crystal cell. In such a liquid crystal meter display section, the liquid crystal, which does not have self-luminous properties, is illuminated mainly by sunlight shining onto the surface of the liquid crystal during the day, and from twilight to night by the illumination of the back surface.

The present invention provides a steering handle that can be accessed from the top bridge of a motorcycle, and has an I-shaped cross section consisting of an upper flat part and a vertical wall part, and the wall part of the vertical part 11 is wide in the center, and has a wide part in the left and right parts. is curved toward the operator and tapered, a notch for a crystal meter display is provided on the vertical wall, and a liquid crystal meter display is provided in the cutout window, which is located elsewhere. The liquid crystal meter display section, which is electrically connected to the drowsiness circuit section and fitted in the center of the steering wheel, is formed to have a slightly concave curved surface toward the driver, and the top plane of the steering wheel, which has a letter-shaped cross section, By placing the illumination light for the crystal meter display section on the bottom surface at 11, the illumination light for the crystal meter display section is placed on the bottom surface, so that it is the same as before during the daytime and during nighttime lighting, and when the display section is exposed to backlight in the morning and evening. Due to the fact that light rays are transmitted through the surface, the segments of the display part become silhouettes, and unnecessary light rays from the sides are absorbed by the left and right parts of the steering wheel, which are curved toward the operator, and the display part in the center part, which has a concave curved surface. To provide a liquid crystal meter display section for a motorcycle, which can prevent plane reflection and enhance display contrast, and which has a smart appearance by eliminating a meter case.

Hereinafter, embodiments of the present invention will be described based on the drawings. Fig. 2 is a perspective view of the Honmoku crystal meter display section provided on the steering handle of a motorcycle, and Fig. 3 is a vertical plan view thereof. , as shown in the figure, the front fork 1 of the motorcycle 10
1. A steering handle 13 is attached to the top bridge 12 which is connected to the upper part of 1.11. The wall portion 13C has a wide center portion 14 and is approximately rectangular, and the left and right portions 1
5 is curved toward the operator and tapered, and a bridge 16 is attached to the tip. The vertical wall portion 13C of the rectangular central portion 14 is provided with a cutout window 13d having the same shape as the liquid crystal meter display portion 17, into which the liquid crystal meter display portion 17 is fitted. It has a sandwich structure of a semi-transparent screen 17C, a protective plate 17a1'm made of glass or plastic on the surface of the liquid crystal meter display unit 11, crystal cells 17b, i...], and a semi-transparent screen 17C on the surface of the motorcycle 10, such as a handle, a trough, etc. It is electrically connected to an electric circuit section disposed at the bottom of the bridge, the fuel tank, the inside of the bottom of the seat, etc. through electrode wiring 17d. The liquid crystal meter display section 17 in the center section 14 displays, for example, speed, engine speed zone and number, gear position, fuel value, engine cooling water temperature, running distance, etc. on a liquid crystal display.

In addition, lights, blinkers and other indicators or warning lights are embedded in the left and right parts 15 with cutouts. As shown in the figure, the rectangular central portion 14 is formed with a slightly concave curved surface toward the operator, and a liquid crystal meter display portion 17 having a similar concave curved surface is fitted into the core portion for display. It is possible to prevent plane reflection from the surface of the part, improve visibility, and add design.

In addition, the upper flat part 13a of the steering handle 13 is made slightly deeper toward the operator in order to add the function of an eaves, and an appropriate number of illumination lights 18 are arranged on the lower surface on the operator's side to illuminate the surface of the liquid crystal meter display section 17. It is used for lighting at night.

As described above, the present invention has a steering handle 13 attached to the top bridge 12 of a Z4+ motorcycle having a ■-shaped cross section consisting of upper and lower flat parts 13a and 13b and a vertical wall part 13C, and the vertical flat part 13C is The center portion 14 is wide, the left and right portions 15 are curved toward the operator side and tapered, and a cutout window 13d of the vertical wall portion 13CKi crystal meter display portion 17 is provided.
A KQ crystal meter display section 17 is provided, and during the daytime when the sun is diagonally behind the pilot in front light SL and during night lighting, the segments of the liquid crystal meter display section 17 are illuminated and easy to see as before, and when the sun is low in the morning and evening. is a backlit S in front of the pilot! In this case, the light rays pass through the semi-transparent screen 17C on the back of the display unit, and the segments of the display unit stand out as silhouettes, and the unnecessary light rays from the sides are transmitted to the left and right parts of the steering wheel 13, which are curved toward the operator. 15, and by forming the display section in the center so as to have a slightly concave curved surface toward the operator, plane reflection from the surface of the display section can be prevented and the contrast of the display can be improved. In addition, by placing the electric circuit section elsewhere and providing only the liquid crystal meter display section 17 on the vertical wall section 13C of the steering handle 13, the meter case is no longer necessary, the area around the steering wheel is made smarter, and it works well with the liquid crystal display. It can give a modern feel.
