Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to an FPC circuit board applied to a sensor and signal system of a new energy vehicle. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and adopt new vehicle-mounted power devices), integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. The sensing and signal systems of new energy vehicles will use FPC circuit boards that are smaller in size and weight, and can be freely bent, wound, folded, and can be arranged arbitrarily according to spatial layout requirements. However, FPC circuit boards are thinner and have lower strength, which can easily cause damage to the soft circuit during installation.

[0003] After searching, in the prior art, Chinese patent publication number: CN220191112U discloses a tear-resistant FPC circuit board, the invention: comprises an FPC circuit board body; a reinforcement plate is symmetrically installed at the bottom of the FPC circuit board body, and a flexible limit strip is provided at the bottom of the reinforcement plate. The invention places the flexible limit strip on the reinforcement plate, and then the user rotates the rotating shaft, and the rotating shaft drives the threaded rod and the fixed plate to move in the threaded hole. After the fixed plate abuts against the flexible limit strip, the flexible limit strip can be abutted and fixed to the bottom of the FPC circuit board body. When the FPC circuit board body is installed, it is inevitable to pull the FPC circuit board body. Since the flexible limit strip is provided, the flexible limit strip will limit the maximum pulling length of the FPC circuit board body, thereby improving the tear resistance of the FPC circuit board body, making it difficult for the FPC circuit board body to break during installation, thereby improving the service life and work efficiency of the FPC circuit board body, and reducing the use cost of the FPC circuit board body.

[0004] But this device still has the following defects:

[0005] To meet different installation environments, operators sometimes need to bend the FPC circuit board to a certain angle for installation. This device makes it difficult to set the FPC circuit board to a certain angle for installation, and when the FPC circuit board is installed at a certain angle, the spring of the device will pull the FPC circuit board, which may cause damage to the connection during long-term use. This device does not solve this problem. Summary of the invention

[0006] The purpose of the present invention is to provide an FPC circuit board used in the sensing and signal system of new energy vehicles. By setting a fixing component, the gold finger part used for connection on the FPC circuit board can be fixed to prevent the connection from being pulled and damaged. In combination with the connection component, the two ends of the FPC circuit board can be installed at a certain angle to meet different installation environments, thereby solving the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] An FPC circuit board used in a new energy vehicle sensor and signal system, comprising an FPC circuit board body, and gold fingers are arranged on both sides of the FPC circuit board body;

[0009] It also includes a fixing assembly for fixing the FPC circuit board body, the fixing assembly includes two sets of fixing seats, threaded rods are fixedly installed on both sides of the top of the fixing seat, a pressing plate is slidably installed on the threaded rod, a fixing nut is arranged above the pressing plate, and the fixing nut is threadably matched with the threaded rod;
