Description

Technical Field

[0001] The utility model relates to a front penetration lamp, belonging to the field of automobile accessories. Background Art

[0002] With the development of electric vehicles, the design of headlights is not only based on functionality, but will develop in the direction of safety and interaction in combination with scenes. At present, many models are equipped with front through-lights, which can enhance the texture of the whole vehicle. At present, the front through-lights include a rear shell and a mask. The PCBA board and the silk screen bracket are installed in the space formed by the rear shell and the mask. The PCBA board and the silk screen bracket are installed in the rear shell through multiple screws. A hollow column matching the screws is fixed in the rear shell. After the screws are connected to the hollow column in a self-tapping manner, the PCBA board and the silk screen bracket are confined in the rear shell. However, when the torque is too large, the hollow column is prone to slipping, resulting in the screws being unable to be installed normally. In severe cases, the entire rear shell needs to be discarded, so it is necessary to design an assembled front through-light. Utility Model Content

[0005] Furthermore, the cross section of the positioning groove is rectangular, the cross section of the portion of the plug-in block in the positioning groove is rectangular, and the plug-in block is a T-shaped structure.

[0006] Furthermore, a plurality of ribs are evenly fixed on the outer surface of the hollow column, and the ribs are connected and fixed to the plug-in block.

[0007] Furthermore, the ribs and the hollow column are an integrally formed structure, the plug-in block and the ribs are an integrally formed structure, and the hollow column and the plug-in block are an integrally formed structure.

[0008] Furthermore, a plurality of card connectors are connected and fixed to the edge of one side of the mask, the card connectors are of L-shaped structure, a plurality of card interfaces matching with the card connectors are provided on the rear shell, and the card connectors are card-connected in the card interfaces.

[0009] Furthermore, a plurality of connecting arms are evenly installed on the upper surface of the rear shell, the connecting arms are L-shaped structures, the connecting arms and the rear shell are an integrally formed structure, and a circular hole for inserting a bolt is opened on one side of the vertical portion of the connecting arm.

[0010] Beneficial effects of the utility model:

[0011] The hollow column is passed through the perforation. At this time, the plug-in block with a rectangular cross-section is in the positioning groove with a rectangular cross-section. The plug-in block and the positioning groove cooperate with each other to prevent the hollow column from rotating, so that the hollow column and the back shell are assembled. The screws pass through the small holes and the PCBA board and are connected to the hollow column in a self-tapping manner to complete the connection and fixation of the PCBA board, the silk screen bracket and the back shell. When the hollow column slips due to excessive torque, the plug-in block and the hollow column are taken out from the channel formed by the positioning groove and the perforation and replaced, so that the hollow column is assembled with the back shell in an assembled manner. When the hollow column slips, the hollow column can be replaced alone without discarding the entire back shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] See also Figure 1-Figure 9 The utility model provides a technical solution: a front through-light, comprising a rear shell 1, in which a PCBA board 6 is installed, wherein the PCBA board 6 is composed of an FPC soft board and an aluminum reinforcement board, and a plurality of RGBLEDs are welded on the FPC soft board. When the vehicle is charging, the front through-light can use red and green to realize charging indication; when the vehicle is parked, different light dance modes with the rhythm of music can be realized, and a turning effect can be realized. When the left turn is turned on, the left side of the front through-light has a left turn effect, and when the right turn is turned on, the right side of the front through-light has a right turn effect. When the double flash is turned on, the left and right sides of the front through-light have a double flash effect, so that each LED can be adjusted separately to realize the light language effect, and the mode can be switched according to different status conditions to realize the human-computer interaction effect.

[0025] See also Figure 1-Figure 9A screen printing bracket 5 is provided on one side of the PCBA board 6, and the screen printing bracket 5 is installed in the rear shell 1. A mask 2 is provided on the side of the screen printing bracket 5 away from the PCBA board 6. The mask 2 is snapped with the rear shell 1, that is, a plurality of card connectors 10 are connected and fixed at the edge of one side of the mask 2. The card connector 10 is an L-shaped structure. A plurality of card interfaces that match the card connector 10 are provided on the rear shell 1, so that the card connector 10 is snapped into the card interface to complete the snap connection between the mask 2 and the rear shell 1. The transparent mask 2 is used as the main appearance surface, which reflects that the lamp shape is more atmospheric. The screen printing bracket 5 uses milky white material as the substrate, and the surface of the screen printing bracket 5 is increased with screen printing laser carving. While meeting the uniformity of the single light source, the whole can be divided into a matrix effect. The electronic part is divided into two parts: a driver board and a PCBA board 6. The driver board uses CAN communication, which can realize the lighting and When the vehicle is turned off, it can also achieve charging, steering and light dance effects. Each LED on the PCBA board 6 can be controlled individually. The PCBA board 6 adopts the structure of FPC soft board + aluminum reinforcement board. The PCBA board 6 can be bent and placed according to the shape of the mask 2, which can meet the distance from each LED to the mask 2, so that the brightness of each LED after passing through the mask 2 is consistent. When the vehicle starts, it enters the welcome mode, and the through-light performs a customized light dance effect, which automatically goes out after 30 seconds. When the signal is sent through the car computer, the driver can choose different modes to interact with information according to his own choice. When the vehicle gives way to pedestrians, the through-light can perform a flowing water effect to remind passers-by. When turning, the through-light displays a yellow flowing arrow to remind other vehicles or passers-by to pay attention to the passing of the vehicle. When parking, the color breathing, flowing water, dancing and other effects can be performed according to the rhythm of music.
