Description

OBD function extension module of car

Technical Field

The utility model relates to an additional equipment of car, especially an OBD function extension module of car.

Background

OBD means an on-board automatic diagnostic system. With more and more automatic systems installed on modern automobiles, an OBD interface is arranged below a steering wheel of an ordinary automobile so as to be used by automobile maintenance personnel for detecting the running state of the automatic systems of the automobiles. For low-configuration automobiles, automobile manufacturers can hide some automatic functions through OBD, such as automatic locking during driving, door opening flashing, reversing flashing, automatic locking during leaving, automatic window lifting and the like. Some low-profile automotive consumers then desire to enable these hidden automation functions through OBD to improve the comfort of use of the vehicle.

Chinese patent No. 201621046003.X discloses a function-switchable OBD device, which is a device for enabling an automation function hidden in a car by an OBD. Its structure is the OBD device contains casing and body, body one end is outer insertion interface, and the other end is control panel, and the characteristic is control panel one end is provided with controlling means, the last at least one switch that is provided with of controlling means, the casing cover is on the body, the casing is provided with the opening with the corresponding position of controlling means who sets up on control panel, the cooperation has the grafting key to come the switching opening on the opening, is equipped with the use of a plurality of mechanical type switch confession start-up a plurality of hidden automation function on the controlling means. The disadvantages of this solution are: when the device is operated, the inserting key is required to be opened, and a plurality of mechanical switches on the control device below the inserting key are pressed through the opening, so that the device is inconvenient to use and operate, and whether the operation is effective or not cannot be identified.

Disclosure of Invention

In order to overcome the problem that the prior art has the use operation inconvenient, and the validity of operation can't be discerned, the utility model aims at providing an OBD function extension module of modified car can overcome prior art's defect.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a OBD function extension module of car, includes the main part and covers and close shell on the main part, the main part top side is equipped with control circuit board, its bottom side is equipped with electricity and passes outer plug-in interface, characterized by: establish one on the shell and press touch control switch, be equipped with the LED display lamp that can make multiple display content on the control circuit board, be equipped with the perspective on the top side of shell and see the perspective region of LED display lamp, press touch control switch with the control circuit board makes corresponding electricity and connects.

The LED display lamp capable of displaying various contents can be a plurality of LED display lamps with different colors or LED display lamp modules capable of displaying characters or numbers.

According to the technical scheme, the LED display lamp capable of making various display contents adopts a plurality of LED display lamps with different colors, and automobile automatic function names corresponding to the LED display lamps can be arranged on the outer surface of the shell in the perspective area or the periphery of the perspective area.

According to the technical scheme, the back face of the shell can be provided with the loudspeaker, the shell can be provided with the sound transmission hole at the position corresponding to the position where the loudspeaker is arranged, and the loudspeaker is electrically connected with the control circuit board correspondingly.

Above-mentioned technical scheme can be equipped with signal wireless transmission receiver on the control circuit board to with the signal wireless transmission receiver butt joint on the car OBD, avoid the trouble of wired connection control.

According to the technical scheme, the touch control switch can be a button switch, a touch switch or a touch switch. The control circuit board can change or enter a control state when the touch control switch is touched once so as to start a hidden automatic control function of the automobile.

The utility model has the advantages that: the circuit board is controlled to enter or change a control state by pressing a touch control switch on the top surface of the shell once, so that a hidden automobile automation function is started, and the convenience of use and operation is effectively improved; because a plurality of LED display lamps on the control circuit board are adopted to display various started automobile automation functions, an operator can conveniently recognize that a certain automobile automation function is started; because the loudspeaker on the back of the shell can inform the starting conditions of various automobile automation functions by sound, an operator can further conveniently know that a certain automobile automation function is started.

The invention is further described with reference to the following figures and examples.
