Description

Technical Field

[0001] This utility model relates to the field of vehicle backlight technology, specifically a vehicle backlight micro-leakage detection device. Background Technology

[0002] Automotive backlighting plays a crucial role in vehicles, affecting both the driver's visual experience and driving safety. Here's a detailed explanation of automotive backlighting: Automotive backlighting refers to the backlighting or backlighting of automotive display devices, as well as lighting equipment installed at the rear or sides of the vehicle. For automotive display devices, backlighting helps improve the visibility of the display screen, especially in low-light environments. For vehicle lighting equipment, backlighting is used to enhance vehicle visibility and safety at night or in low-visibility conditions. Automotive backlighting mainly includes the following types: LED backlighting: This is the most common type of automotive backlighting. LEDs have advantages such as small size, high brightness, and low energy consumption, and are widely used in automotive display devices and lighting systems. Mini LED backlighting: Mini LED is an upgraded version of LED. Its smaller size allows for higher pixel density and finer local dimming, thus improving display effects. Mini LED backlit screens have broad application prospects in the automotive display field. Other types of backlighting: In addition to LED and Mini LED, there are other types of backlighting technologies, such as OLED (organic light-emitting diode), but they are less commonly used in the automotive field.

[0003] According to patent announcement number CN220188589U published on the China Patent Network, this utility model relates to the technical field of micro-leakage current detection devices, and discloses a vehicle-mounted backlight micro-leakage current detection device, including a worktable. A positioning groove is formed inside the worktable, and a rectangular contact piece is fixedly installed on the side of the positioning groove. An adjustment device and a lamp holder are fixedly installed on the top of the worktable. The adjustment device includes a fixing frame, a screw, a connecting wire, and a knob. The fixing frame is fixedly installed on the top of the worktable. This vehicle-mounted backlight micro-leakage current detection device, by setting an adjustment device, allows for the detection of a corresponding vehicle-mounted backlight module. Rotating the corresponding knob changes the relative position of the knob, causing the effective length of the screw in the adjustment device connected to the lamp holder, connecting wire, and knob to continuously change, thereby adjusting the leakage current range. When the leakage current value of the vehicle-mounted backlight is within the adjusted range, the observation lamp will light up.

The transmission plate 43 drives the toothed plate 44 to the right, and the toothed plate 44 meshes with the first gear 45, causing the first gear 45 to rotate. The first gear 45 meshes with the second gear 46, causing the second gear 46 to rotate. The second gear 46 drives the transmission column 47 to slide inside the moving plate 48 and drives the moving plate 48 to move forward. The moving plate 48 drives the connecting block 49 and the clamping plate 410 to move forward, releasing the limit on the mounting slot 2. At the same time, when the first gear 45 rotates, it drives the threaded connecting screw 51 to move upward through the threaded connection screw 51. The screw 51 drives the transmission rod 52 to move upward, and the transmission rod 52 drives the adjusting limit plate 53 to move upward. Then, the user installs the vehicle backlight strip 3 into the mounting slot 2 of the micro leakage current detector 1. The reverse operation can quickly fix the vehicle backlight strip 3.
