Description

Technical Field

[0001] This invention relates to the field of flashlights, and more specifically to a flashlight containing a horizontal control circuit board. Background Technology

[0002] As a portable lighting tool, the structure and function of flashlights have continuously evolved with technological advancements. Modern high-performance flashlights are no longer limited to providing basic illumination; they typically integrate multiple functions, such as battery level display, multi-level brightness adjustment, and strobe mode. The realization of these functions relies on a built-in control circuit board and its associated input and output components.

[0003] In traditional flashlight designs, the control circuit board is typically arranged vertically, meaning the board surface is perpendicular to the axis of the flashlight's metal body. This layout has several inherent drawbacks: First, the vertical arrangement causes the circuit board and its functional modules (such as microcontrollers and display driver units) to occupy a significant amount of space along the axial direction within the flashlight body, resulting in a less compact overall structure and hindering miniaturization. Second, components such as the display screen and control buttons often need to be separately mounted at the opening in the flashlight body and connected to the vertical main control circuit board via wires. This distributed layout increases the number and complexity of internal cables, raising production costs and requiring cumbersome soldering and wiring steps during assembly, significantly reducing production efficiency. Furthermore, the cable connections are susceptible to loosening or short circuits, affecting product reliability.

[0004] Furthermore, to achieve circuit continuity, traditional designs typically employ a conductive spring that directly contacts the battery electrodes. In vertical circuit board structures, this conductive spring is usually soldered directly to the circuit board surface. When the battery is installed, it applies continuous axial pressure to the conductive spring, which is directly transmitted to the circuit board itself. Over time or under impact, this can easily lead to circuit board bending, solder joint cracking, or component damage, affecting the product's lifespan and stability. Summary of the Invention

[0005] To address the above problems, the present invention provides a flashlight containing a horizontal control circuit board:

[0006] A flashlight containing a horizontal control circuit board includes a light source assembly, a metal body, a tail cap, a battery assembly, and a control assembly. The light source assembly and the tail cap are respectively connected to both ends of the metal body. The battery assembly and the control assembly are installed inside the metal body. The control assembly includes a circuit compartment and a control circuit board disposed in the circuit compartment. The control circuit board has a horizontal structure parallel to the metal body. A display screen and control buttons are connected to the upper part of the control circuit board.

[0007] Preferably, the control component is detachably installed inside the metal cylinder. The control circuit board is connected to a positive input terminal connected to the positive terminal of the battery assembly, a positive output terminal connected to the positive terminal of the light source assembly, and a negative input terminal connected to the negative terminal of the battery assembly. The positive input terminal and positive output terminal are respectively fixedly connected to the two ends of the circuit compartment by helical conductive springs. The negative input terminal includes an arc-shaped conductive strip electrically connected to the metal cylinder, and the arc-shaped conductive strip is fixedly connected to the end of the circuit compartment. The control component of this application adopts an integrated assembly structure, which can be directly filled into the metal cylinder. The contact electrical connection can be achieved by the natural contact of the helical conductive spring and the arc-shaped conductive strip, without the need for additional connection through corresponding wires, which greatly saves the corresponding assembly steps.

[0008] Preferably, the positive and negative input terminals are connected to the positive and negative terminals of the battery, respectively. The spiral conductive spring includes an integrally connected spiral conductive part and a central conductive strip part. The central conductive strip part passes through the circuit compartment and is electrically connected to the control circuit board. The spiral conductive part at the positive input terminal abuts against the positive terminal of the battery assembly and the circuit compartment, respectively. The spiral conductive part at the positive output terminal abuts against the positive terminal of the light source assembly and the circuit compartment, respectively. Existing vertical control circuit boards directly mount the conductive spring on the surface of the control circuit board. After the battery assembly is installed, the battery assembly applies pressure directly to the surface of the control circuit board through the conductive spring, which can easily damage the circuit board. This application, however, directly positions the spiral conductive part at the end face of the battery compartment corresponding to the battery assembly. In addition to the conventional elastic abutment effect, the spiral conductive part's spiral disc structure ensures that the pressure from the battery assembly is evenly distributed across the end face of the battery compartment without causing pressure damage to the control circuit board.

[0009] Preferably, the positive output terminal and the negative input terminal are both located at one end of the corresponding light source component in the circuit compartment. The spiral conductive part of the positive output terminal extends spirally along the axial direction of the circuit compartment. The spiral conductive part of the positive output terminal is fitted with an annular flange that is integrally fixed to the end face of the circuit compartment. The outer surface of the annular flange is provided with an annular locking groove. A metal conductive ring is installed in the annular locking groove. The metal conductive ring and the circuit compartment form abutment and limiting fit. The metal conductive ring and the circuit compartment clamp an arc-shaped conductive strip. The metal conductive ring is electrically connected to the arc-shaped conductive strip. The metal conductive ring and the annular inner locking groove provided on the inner side of the metal cylinder form a locking fit.

[0010] It also includes an elastic locking buckle, which includes an annular sleeve that is fixedly fitted to the metal cylinder body and an elastic locking strip that is fixedly connected to the annular sleeve. The elastic locking strip and the surface of the metal cylinder body form a clamping mechanism.

[0011] The metal cylinder is provided with a first opening and a second opening for the display screen and control buttons. The first opening is fixedly connected to a transparent cover for the display screen, and the second opening is fixedly connected to an elastic rubber sleeve for the control buttons.

[0012] Beneficial Effects: This invention creatively employs a horizontally arranged control circuit board, parallel to the axial direction of the flashlight's metal body. This layout allows for the high integration of the display screen, control buttons, and all related control modules into a unified control component. This control component, as an independent module, can be detachably installed within the metal body. This simplifies the flashlight assembly process to the rapid plug-in and combination of several main modules, greatly simplifying the assembly process, improving production efficiency, and facilitating subsequent maintenance and replacement.
