Abstract
A digitized electronic indicator for position of gear on the motorcycle of the utility model makes use of the photoelectric principle to carry out work. The technical feature of the utility model is that the mechanical motion of the motorcycle is converted to digitized display and then is showed out by the position of gear change through a plurality of elements such as a touch switch and a decoder digitized display device. The utility model can help the driver to recognize the position of gear exactly during the motorcycle running to avoid the abrasion and danger of the motorcycle which is caused by wrong inversing of the position of gear. The structure has a simple and safe installing technology.
Description
The gear that the utility model relates to the motorcycle of a kind of gear display device of motor vehicles, particularly various models shows.
The various vehicles of China's production at present and import all do not have the conversion of the motorcycle gear of shift indicator, particularly various models not have virtual display unit spare to be distinguished.Can only be memoriter during driving with speed feel judged, but the third gear of motorcycle, fourth gear is not easily distinguishable, and the gear shift error is often arranged, and occurs a kind of " locking-type brake " phenomenon, the generation car is spoken sarcastically and is hindered accident.
The purpose of this utility model provides a kind of gear display device, and it can be intuitively be shown to the driver with the gear of vehicle.
The purpose of this utility model is achieved in that display is to utilize photovoltaic principals, transfers the conversion of gear to digital form and shows on display intuitively.Display is by contact-making switch, code translator, three major parts of display are formed, contact-making switch 5 is made by bakelite powder die casting, contact is decided in 5 of interior pore size distributions, be used for receiving gear signal, code translator 1 is by circuit board, and it can be discrete component that semiconductor element is welded to form, also can be integrated component, reaches the water, shock requirement with the epoxide-resin glue sealing then.It act as the digital indicator coding, and its logic function is listed by following table.
Logical table
Its circuit theory is seen Figure of description 2; Display 3 selects for use LED7 to draw digital indicator also can be the LCD LCD, does the terminal numeral and shows.
Shown in Figure of description 1: A that dotted line is drawn together is the contact-making switch part; B is the code translator part; C is the digital indicator part, among the figure element by code translator 1, chip combined inserting device 2,6, compositions such as display 3, cylindrical single line socket 4, contact-making switch 5, motorcycle engine shift cam axle 7, contact-making switch moving contact 8.Its principle of work, contact-making switch 5 in the gearshift display device is decided contact by a moving contact and 5 and is formed, moving contact 8 is screwed on speed change spindle nose 7 and links with variable-speed shaft, decide contact and be divided into 1---4 grades and 5 contacts of neutral gear, decide contact and be connected with chip combined inserting device 6 with code translator 1 respectively, code translator 1 connects with chip combined inserting device 2 with display 3.During vehicle speed variation, variable-speed shaft produces circular motion, and each gear produces 72 ° of corners, and moving contact just joins with the different contact of deciding.Owing to decide contact and connect, so the variation of the logical circuit of code translator 1 just changes along with the difference of the moving contact of contact-making switch 5 with code translator 1 circuit.This variation can show by the form of display 3 with numeral.
This utility model can be installed on the various pedal gear change formula motorcycles, and it can be avoided because the damage car that causes of missed shift position, and casualty accident reduces the vehicle rate of wear of parts in addition simultaneously, prolongs the serviceable life of vehicle.
Figure of description 1: electronic digit gearshift display device structural drawing.
Figure of description 2: electronic digit gearshift display device circuit theory diagrams:
Provide one below in conjunction with Figure of description 1 embodiment is installed: (is example with Jinan K90 type motorcycle)
1, the installation of contact-making switch 5:
Unloaded engine left side generator flywheel protecting cover, take off former neutral switch lid, the moving contact 8 of the neutral switch of former car is constant, subsequently contact-making switch 5 is changed, connecting conducting wire by the different colours of line receive respectively contact- making switch 50,1,2,3,4, shelves binding post on.
2, the installation of code translator 1:
Code translator 1 in packing shell into, the wire hole of headlight shell is got final product.
3, the installation of display 3:
Open the instrument loam cake, digital indicator 3 is contained on the position of former neutral gear lamp, subsequently plug connector is inserted, added+the 6V live wire inserts 4 and connects with the live wire of former neutral gear lamp with first cylindricality is single, load onto the flywheel protecting cover, load onto the instrument loam cake, the opening power master switch just can be devoted oneself to work.
Claims (3)
1, a kind of electronic digit gearshift display device that is used on the motorcycle is characterized in that: utilizes the photoelectric display principle, the variation of gear is converted to digital form, display intuitively,
Indicator is formed vehicle moving contact when a certain gear by contact-making switch (5) code translator (1) display (3) and is just decided contact with one of them and join, and electric power loop is connected, and code translator (1) promotes digital indicator (3) and carries out work.
2, according to claim, 1 described device is characterized in that: display is LED light emitting diode and LCD LCD.
3, according to claim, described device, its unique point is code translator (1), can be integrated component or forms with discrete component, can use on other big-and-middle-sized passenger-cargo carriage if change the form of contact-making switch (5).
