Description

Electronic shift lever

The present invention relates to an electronic shift lever device for controlling a mission shift stage of a vehicle using an electrical signal.

The electronic shift lever device refers to a lever device for controlling a shift stage of a mission through an electrical signal using a substrate instead of a mechanical link structure through a wire as a means for shifting the shift stage of a mission from a shift lever of a vehicle in the past.

Unlike the mechanical shift lever device, the electronic shift lever device converts the information of the shift stage selected by the user into an electrical signal, thereby simplifying the connection means between the lever device and the mission, as well as inadvertent movement of the lever. To prevent gear shifting.

Recently, the electronic shift lever device adopts a method using a magnet and a Hall sensor to detect a selected shift stage, which converts the magnetic force of the magnet into an electrical signal by detecting the magnetic force of the magnet and uses the same. It is possible to easily control the shift stage of the mission.

Referring to "Electronic Transmission" of Korean Patent Application Laid-Open Publication No. 10-2009-0111111, the conventional lever operation means has two guides that guide the shift to the X-axis and the Y-axis so that the lower end of the lever is supported. It consists of an organically coupled configuration from the lever. To date, most of these types of operation means. This type of operation means supports the lower part of the lever and configures the operation means on the upper part, so that the number of configurations is large, the organic coupling relationship between each other is complicated, and the cost of manufacturing and assembly of each component is difficult. Is raised, there is a problem that the operation feeling is not smooth because the lever is moved to the joint type.

Next, referring to the conventional sensing means, a magnet is installed at one end of one of the two guides, and the board having the hall sensor is mounted so as to be mounted vertically on the side of the lever to face the magnet. Such a sensing means has a problem in that a detection error occurs frequently because the movement gap of the shift stage is narrow since the magnet and the hall sensor are positioned on the side of the lever. Referring to FIGS. 2 and 3 of the prior art document (Patent Publication No. 10-2009-0111111), in the case of + stage and R stage, M stage and N stage, and-stage and D stage, the select is determined by a minute gap in the same shift direction. This occurs because the Hall sensor is difficult to read this difference. Such sensing means cannot be used in the case of a gate type in which a select overlaps in the shift direction rather than the gate type suggested in the prior art document. In addition, in the case of a shift stage in which the magnet and the hall sensor are far away, there is a problem in that the shift stage is not detected. This occurs when the distance between the magnet and the Hall sensor in the D stage, R stage, and N stage is considerably farther with reference to FIGS. 2 and 3 of the prior art document, because the force of the magnetic force is weakened. Another example is a configuration in which two substrates are mounted vertically on the side of the lever. This increases the number of configurations, as well as reading the shift stage with a combination of sensing on two substrates, which requires additional circuit configuration and controllers.As mentioned above, there is still a blind spot where the magnet and the hall sensor are separated. There is a problem that the detection ability is poor.

Next, referring to FIG. 2 of the prior art document (Patent Publication No. 10-2009-0111111), referring to the structure of the main body and the gate cover, a gate groove is formed in the upper part of the main body, and the gate groove is formed in the gate cover. have. Since the preferred gate shape varies depending on the manufacturer, when the gate shape is changed, the entire lever transmission must be replaced or newly manufactured, and the main body cannot be used interchangeably, and AT and MT cannot be shared. There is a problem.

The present invention was developed in view of the related art, and in particular, the lever operation means and the detection means are simplified, and the operation and detection are more smooth, and the compatibility of the main body according to the shape of the common and gate according to AT and MT The purpose is to make it possible.

In order to achieve the above object, the present invention, in the electronic lever shifting device, the lower portion of the lever ball coupling to the main body, a magnet mounted on the lower end of the lever, the substrate on which the Hall sensor is disposed on the bottom of the magnet horizontal And the mounting, and the inner top / bottom of the main body by combining so that the gate cover and the substrate can be replaced from the main body.

The present invention as described above, by providing the lever operating means of the ball coupling type, it is possible to significantly simplify the configuration of the conventional articulation type operation means, as well as the displacement of the lever is free, there is a soft operation feeling.

In addition, by providing a bottom recognition sensing means, the configuration of the conventional side-position sensing means and plural sensing means can be significantly simplified, as well as the accuracy of detection, prevention of inability to detect, and easy compatibility with various gate shapes. There is one effect.

In addition, by providing the upper and lower open coupling means, the shape of the gate can be freely changed and replaced, as well as the AT and MT can be used in common, and the main body is compatible.
