Abstract

The utility model discloses a steering wheel gear shift device. The device is characterized in that a gear request key unit and a gear shift up and down key unit are connected with a gear shift switch control module respectively, wherein the gear shift switch control module is connected with a gear box module through a CAN (Controller Area Network) bus; and the gear box module controls a gear shift mechanism to act. Since the structure is adopted, the steering wheel gear shift device has the advantages that the peripheral interface of the gear box is simplified, the device has high stability and is widely applied to the field of automobiles and a working indicator lamp and a backlight indicator lamp of a steering wheel gear shift key can be driven to facilitate the gear shift operation of a driver.

Description

A kind of bearing circle gearshift

Technical field

The utility model relates to automobile manufacturing field, particularly a kind of bearing circle gearshift.

Background technology

Along with improving constantly of Automobile manufacturing level, bearing circle this function of shifting gears is more and more universal, is applied on different vehicles.

At present, direction of operating dish switch realizes that gearshift comprises that bearing circle button switch, change speed gear box module, gearbox shifting mechanism and relevant rattail form.Driver's operation bearing circle shift switch, the direct receiving key signal of change speed gear box module, and drive corresponding gearshift and realize the gearbox shifting process.But cause the wire harness that connects between shift switch button and change speed gear box module very long very thick because the shift switch button is more.The change speed gear box module is directly processed bearing circle shift switch signal, causes change speed gear box module peripheral interface to increase, and change speed gear box reception multichannel mechanical switch signal, and resistance to overturning is difficult for assurance, and loss and the mistake of every road signal all will cause system mistake; Extendability is relatively poor, is unfavorable for the expansion of bearing circle button, and reaching each expansion to the bearing circle button all needs the change speed gear box module is changed.

Improve a kind of novel bearing circle gearshift for the problems referred to above, to simplify the peripheral interface of change speed gear box module, improving stability is the problem that prior art need to solve.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of bearing circle gearshift, to reach the peripheral interface of simplifying the change speed gear box module, the purpose of raising stability.

For achieving the above object, the technical solution of the utility model is that a kind of bearing circle gearshift is characterized in that: described device is that gear request key unit, gear plus-minus push-button unit access respectively the shift switch control module; The shift switch control module connects the change speed gear box module by the CAN bus, the action of change speed gear box module controls gearshift, thereby process various key informations by the shift switch control module, concentrated and change speed gear box module is carried out CAN communication control gearshift and is carried out the gear conversion.

Described shift switch control module connects indication output unit backlight, thereby various buttons are carried out indication backlight.

Described shift switch control module connection work indication output unit, thus the mode of operation of whole device is carried out lamplight pointing.

Described shift switch control module connects car load pwm signal backlight.

A kind of bearing circle gearshift owing to adopting above-mentioned structure, the utility model has the advantage of: the peripheral interface of 1, having simplified change speed gear box; 2, stability is strong, is widely used at automotive field; 3, can and relay indicating light and the indicator lamp backlight of driving direction dish shift key, facilitate the chaufeur gear shift operation.

Description of drawings

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;

Fig. 1 is a kind of bearing circle gearshift structured flowchart of the present utility model;

Fig. 2 is the bearing circle front arrangement plan of a kind of bearing circle gearshift of the present utility model;

Fig. 3 is the bearing circle back side arrangement plan of a kind of bearing circle gearshift of the present utility model;

In Fig. 1,1, the shift switch control module; 2, change speed gear box module; 3, indication output unit backlight; 4, work indication output unit; 5, gear plus-minus push-button unit; 6, gear request key unit; 7, gearshift.

The specific embodiment

As shown in Figure 1, the utility model is that gear request key unit 6, gear plus-minus push-button unit 5 access respectively shift switch control module 1; Shift switch control module 1 connects change speed gear box module 2 by the CAN bus, change speed gear box module 2 is controlled gearshift 7 actions, thereby process various key informations by shift switch control module 1, concentrated and change speed gear box module 2 is carried out CAN communication control gearshift 7 and is carried out the gear conversion.

Shift switch control module 1 connects indication output unit 3 backlight, thereby various buttons are carried out indication backlight.Shift switch control module 1 is connection work indication output unit 4 also, thereby the mode of operation of whole device is carried out lamplight pointing.Shift switch module 1 also connects car load (pwm signal) backlight input.

The utility model is by newly-increased shift switch control module 1, the on-off signal of shift switch control module 1 receive direction dish shift key, and the request signal of should shifting gears sends to change speed gear box module 2 by the CAN bus, and change speed gear box module 2 receives CAN bus message signals and drives corresponding gearshift 7 and realizes shift process.To shift switch control module 1, shift switch control module 1 receives respective signal and drives corresponding relay indicating light change speed gear box module 2 by the current gear signal iso-variable velocity case status signal of CAN bus feedback.Shift switch control module 1 receives simultaneously other status signals such as car load backlight signal and drives corresponding shift switch indicator lamp backlight.

Shift switch control module 1 of the present utility model gathers bearing circle button request signal, and 2 needs of change speed gear box module receive message signals by the CAN bus.The great like this peripheral interface of simplifying change speed gear box.Shift switch module 1 sends request signal to change speed gear box module 2 by the CAN bus, and change speed gear box module 2 receives the CAN signal and drives controls gear shift operation.Because the CAN bussing technique is ripe, stability is strong, automotive field is widely used.The whole system complexity is reduced, and stability strengthen, is convenient to expansion and the transplanting of systemic-function.Shift switch control module 1 can receive other states such as gear of change speed gear box module 2 feedbacks simultaneously by the CAN bus simultaneously, receives other signals from car load, and the relay indicating light of driving direction dish shift key and indicator lamp backlight.Facilitate the chaufeur gear shift operation.

The above is exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as the various improvement of having adopted technical solutions of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
