The OBD vehicle-mounted device according to the embodiment of the present invention is described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 4, an OBD vehicle-mounted device according to an embodiment of the present invention includes a housing 10, an OBD connector 20, an LED light source 30, and a power source 40.
Specifically, the housing 10 has a plugging end D10, the plugging end D10 is provided with a receiving cavity P10, and the front side of the receiving cavity P10 is opened to form an opening P101, as in the examples of fig. 1 and 2, the front end of the housing 10 is the plugging end D10.
The OBD connector 20 includes an OBD pin 201 and a guide member 202, where the OBD pin 201 is disposed in the accommodating cavity P10 and one end of the OBD pin extends toward the opening P101, and the guide member 202 is made of a light-transmitting material, and the guide member 202 is disposed in the accommodating cavity P10 and one end of the guide member extends toward the opening P101.
The OBD connector 20 is configured to cooperate with an automobile OBD diagnostic interface to obtain data of an automobile from the automobile OBD diagnostic interface, wherein the OBD pin 201 is configured to electrically connect with a pin hole in the automobile OBD diagnostic interface, that is, when the plugging end D10 is plugged into the automobile OBD diagnostic interface, the OBD pin 201 is plugged into the pin hole in the automobile OBD diagnostic interface. The guide 202 is used for guiding the insertion end D10 to be inserted along a predetermined direction when the insertion end D10 is inserted into the automobile OBD diagnostic interface, so that the OBD pin 201 can be smoothly inserted into the pin hole in the automobile OBD diagnostic interface.
Illustratively, as shown in fig. 2, the guide 202 is configured as a flat sheet body that extends in the front-rear direction and has a width several times that of the OBD pin 201, which can provide a good guiding effect.
Of course, it is understood that the shape of the guide 202 of the present embodiment is not limited thereto, and the guide 202 may be configured in other shapes, such as a cylinder, a prism, a cone, etc.
An LED light source 30 is disposed within the housing 10 adjacent to the OBD connector 20, the LED light source 30 being configured such that light therefrom is capable of passing through the guide 202 and exiting the opening P101.
That is, the light emitting direction of the LED light source 30 is directed to the guide 202, and since the guide 202 is made of a light-transmitting material, the light of the LED light source 30 can be emitted through the guide 202. In the example of fig. 2, the guide 202 extends in the front-rear direction, and correspondingly, the LED light source 30 is disposed at the rear of the guide 202, and when the LED light source 30 is turned on, the emitted light irradiates toward the front and is emitted from the opening P101 after passing through the guide 202, so that the emitted light can illuminate the front environment.
The power supply 40 is electrically connected to the LED light source 30, and is used for supplying power to the LED light source 30. For example, the power supply 40 may include a rechargeable battery and a power circuit, where the power circuit is electrically connected to the rechargeable battery and the LED light source 30, and may convert the dc power output by the rechargeable battery into the dc power suitable for the LED light source 30, so as to supply power to the LED light source 30, so that the LED light source 30 can work by emitting light.
According to the OBD vehicle-mounted device provided by the embodiment of the invention, the LED light source 30 is arranged, the light emitted by the LED light source 30 can be emitted from the opening P101 after passing through the guide piece 202, so that when the OBD vehicle-mounted device is connected to an automobile OBD diagnosis interface, the LED light source 30 can be turned on, and the light of the LED light source 30 is emitted from the opening P101, so that a user can conveniently and quickly align the automobile OBD diagnosis interface and insert the connection. In addition, the LED light source 30 transmits light by using the guide member 202, so that the light emitted from the opening P101 is more uniform, and the lighting effect is better.
Referring to fig. 3 to 4, in some embodiments of the present invention, the portable electronic device further includes a key 50 and a processing module 60, wherein the key 50 is disposed on the housing 10; the processing module 60 is disposed in the housing 10 and electrically connected to the key 50 and the power source 40, and is configured to control the power source 40 to be turned on or off according to a signal triggered by the key 50.
That is, the key 50 can be operated by a user to trigger generation of a control signal, the processing module 60 controls the power source 40 to be turned on or off according to the control signal after receiving the control signal, and correspondingly, when the power source 40 is turned on, the LED light source 30 is turned on, and when the power source 40 is turned off, the LED light source 30 is turned off, so that the on/off control of the LED light source 30 can be realized, so that the user can turn on the LED light source 30 when needed, and control the LED light source 30 to be turned off when not needed through the key 50.
For example, as shown in fig. 3, the key 50 is disposed at the rear end of the housing 10 for user operation, and of course, the key 50 may be disposed at other positions on the housing 10 for user operation as desired.
Advantageously, the key 50 may be a self-locking key, so that when the user presses the key 50 for the first time, the key 50 is turned on and kept, i.e. self-locked, and when the key 50 is pressed for the second time, the key 50 is turned off and bounces, thus facilitating the use and operation.
Of course, it is understood that other key structures known in the art may be used for the key 50.
Referring to fig. 4, in some embodiments of the present invention, a processing module 60 is electrically connected to the OBD connector 20, for detecting a connection state between the OBD connector 20 and a diagnostic interface of an automobile, and controlling the power supply 40 to be turned off when the OBD connector 20 is detected to be connected to the diagnostic interface of the automobile.
Typically, the OBD pins 201 in the OBD connector 20 are multiple, for example, standard 16 pins, and correspondingly, the pin holes in the automobile diagnostic interface are also 16 holes. After the OBD connector 20 is plugged with the automobile diagnosis interface, each OBD pin 201 in the OBD connector 20 is correspondingly plugged with each pinhole in the automobile diagnosis interface, and at least part of the OBD pins 201 generate signals when plugged. For example, the 4 th pin and the 16 th pin are the body ground, the 16 th pin is the positive voltage, after the 4 th pin and the 16 th pin are plugged with the 4 th pin hole and the 16 th pin hole in the automobile diagnosis interface, the power supply 40 can be obtained from the automobile power supply 40, and the corresponding 4 th pin and 16 th pin generate signals, at this time, the processing module 60 can judge that the OBD connector 20 is connected with the automobile diagnosis interface according to the signals generated by the 4 th pin and the 16 th pin.
And when the processing module 60 detects that the OBD connector 20 is connected with the automobile diagnosis interface, the processing module 60 may output a control signal to the LED light source 30 to control the power source 40 to be turned off, and correspondingly, the LED light source 30 to be turned off.
That is, when in use, a user can turn on the LED light source 30, and illuminate with the LED light source 30, so as to conveniently insert the OBD connector 20 into the automobile diagnosis interface. When the OBD connector 20 is inserted into the automobile diagnosis interface, the OBD connector 20 generates a signal, and the processing module 60 detects that the OBD connector 20 is connected with the automobile diagnosis interface according to the signal generated by the OBD connector 20, so as to control the LED light source 30 to be turned off.
Since the LED light source 30 is not needed after the OBD connector 20 is inserted into the automobile diagnosis interface, but at this time, the LED light source 30 is located in the automobile diagnosis interface, and the light thereof is not basically irradiated to the outside, so it is difficult for a user to find whether the LED light source 30 is turned off, and once the user forgets to manually turn off the LED light source 30, the LED light source 30 is always in a lighted state, which wastes electric energy, and at the same time, the LED light source 30 is easily damaged. In this embodiment, the processing module 60 actively turns off the LED light source 30 after the OBD connector 20 is connected to the diagnostic interface of the automobile, so as to avoid the above-mentioned problems.
In other embodiments of the present invention, the processing module 60 is further configured to control the power source 40 to remain on when it is detected that the OBD connector 20 is not connected to the automotive diagnostic interface.
That is, if the OBD connector 20 is not successfully connected with the automobile diagnostic interface, the processing module 60 controls the power supply 40 to be always turned on, correspondingly, the LED light source 30 is always on, and thus the user can insert the OBD connector 20 into the automobile diagnostic interface conveniently, and the use is more convenient and humanized.
Referring to fig. 1 to 3, in one embodiment of the present invention, a housing 10 includes a body 101 and a socket 102, a circuit board 11 is disposed in the body 101, and the processing module 60 is disposed on the circuit board 11; the connector seat 102 is detachably connected to one end of the housing 101, the accommodating cavity P10 is formed on the connector seat 102, and the OBD pin 201 is electrically connected to the processing module 60 through the circuit board 11.
That is, the housing 10 is mainly composed of a housing body 101 and a connector seat 102, the connector seat 102 is detachably connected with the housing body, for example, by fastening connection, threaded connection, or the like, the OBD pin 201 is disposed in the housing cavity P10 in the connector seat 102 and electrically connected with the circuit board 11 in the housing body 101, and the processing module 60 is electrically connected with the circuit board 11, so that the OBD pin 201 can electrically connect the circuit board 11 with the processing module 60, and the structure is simple and the assembly is convenient.
Advantageously, in one example of the present invention, the housing cavity P10 has a bottom wall 1021 opposite to the opening P101, and the OBD pin 201 and the guide member 202 are inserted through and fixed to the bottom wall 1021, for example, the connector block 102 is an injection molded part, and the OBD pin 201 is injection molded and fixed to the connector block 102, so that the OBD pin 201 and the guide member 202 are more stable.
Referring to fig. 2, in one embodiment of the present invention, an adapter plate 12 is disposed in the housing 10, the adapter plate 12 has an adapter pin 121 thereon, and the OBD pin 201 is electrically connected to the adapter pin 121 through the adapter plate 12; the circuit board 11 is provided with a terminal block, and the terminal block is inserted into the adapting pin 121, so that the adapting pin 121 is electrically connected with the processing module 60 through the terminal block.
That is, the OBD pin 201 is electrically connected to the adapter plate 12, the adapter plate 12 is electrically connected to the terminal block on the circuit board 11 through the adapter pin 121, and the terminal block is electrically connected to the processing module 60 through the circuit board 11, so that the OBD pin 201 is electrically connected to the processing module 60.
In one embodiment of the present invention, the other end of the guide 202 is provided with a groove 2021, and the LED light source 30 is disposed on the interposer 12 and is accommodated in the groove 2021. In this way, the light emitted by the LED light source 30 can enter the guide member 202 in a large amount, and the light is concentrated and uniformly emitted by the guide member 202, so that the light emitted by the opening P101 of the plugging end D10 is more uniform and brighter.
For example, the number of the guide members 202 and the LED light sources 30 is two, and the two guide members 202 are arranged in one-to-one correspondence with the two LED light sources 30. In this way, the two guides 202 and the two LED light sources 30 can make the light more uniformly emitted toward the opening P101, so that the light emitted from the opening P101 is more uniform.
Referring to fig. 2, in one embodiment of the invention, the one end of the OBD pin 201 is spaced from the opening P101 a greater distance than the one end of the guide 202 is spaced from the opening P101. Thus, when the OBD connector 20 is plugged with the automobile diagnosis interface, the guide 202 contacts with the automobile diagnosis interface, and after the guide 202 is matched with the guide hole in the automobile diagnosis interface, the OBD pin 201 is guided to be smoothly inserted into the pinhole by utilizing the guiding function, so that the problem of bending and the like caused by inaccurate positioning when the OBD pin 201 directly enters the automobile diagnosis interface is avoided, that is, the function of protecting the OBD pin 201 can be achieved.
For example, a display 70 may be further disposed on the housing 101, and the display 70 is electrically connected to the processing module 60, so that the obtained data of the automobile may be implemented through the display 70.
