Technical Field
[0001] This utility model relates to a battery charger with a display screen mounted on the back of the motherboard, belonging to the field of charger design technology. Background Technology
[0002] With the increasing popularity of electric bicycles, chargers for these bicycles are becoming increasingly important. Existing chargers consist of an upper shell and a lower shell. The upper shell has an upper cavity with one open end, and the lower shell has a lower cavity with one open end. The upper and lower shells are screwed together for secure connection, forming a receiving cavity. A main board is installed within this cavity, and an LCD screen is connected to it for easy monitoring of the charging status. In existing battery chargers, the LCD screen and backlight are mounted on a display panel, which is then fixed to a display bracket. The display bracket is fixed to the front of the main board, thus securing the display panel to the main board and placing the screen on the front of the main board. This current display mounting method presents a cost issue: the LCD screen and backlight are mounted on the display panel, which is then fixed to the front of the main board via the display bracket. This structure adds the display panel component, hindering cost reduction. Utility Model Content
[0003] The purpose of this invention is to address the aforementioned problems by providing a battery charger with a display screen mounted on the back of the motherboard that is advantageous for cost reduction.
[0004] To achieve the aforementioned utility model objectives, the technical solution adopted by this utility model is as follows: A battery charger with a display screen mounted on the back of a motherboard includes an upper housing and a lower housing. The upper housing has an upper cavity with one end open, and the lower housing has a lower cavity with one end open. The upper and lower housings are fixedly connected, and the upper and lower cavities form a receiving cavity. A motherboard is installed within the receiving cavity, and the motherboard is fixed to the upper housing and / or the lower housing. A display window is provided on the upper housing. Its characteristic is:
[0005] The back of the motherboard is equipped with a display bracket and an LCD screen and an LCD backlight. The LCD screen and LCD backlight are installed and fixed on the display bracket in sequence, with the back of the LCD screen and the LCD backlight attached to each other. The front of the LCD screen faces the display window of the upper housing. Both the LCD screen and the LCD backlight are connected to the motherboard.
[0006] The upper and lower housings are screwed together for fixation.
[0007] An upper vest is installed on the upper shell, and a lower vest is installed on the lower shell.
[0008] The vest has a vest window, and a face sticker is affixed to the upper shell. The face sticker is placed inside the vest window and covers the display window.
[0009] This utility model has a reasonable structure and mainly improves upon existing chargers by mounting the LCD screen and LCD backlight on the back of the motherboard, instead of the traditional front. A display bracket is installed on the back of the motherboard, and the LCD screen and LCD backlight are sequentially fixed to the bracket. The front of the LCD screen faces the display window on the charger's upper casing, allowing the user to observe the charging status. Both the LCD screen and LCD backlight are connected to the motherboard to ensure normal display function.
[0010] In this invention, a faceplate is affixed to the display window of the upper housing, covering the display window and placed inside the upper housing window. This design not only protects the LCD screen from direct damage from external scratches and impacts, but also maintains the transparency of the display window, ensuring that the user can observe the charging status.
[0011] The upper and lower casings are fitted with upper and lower heat spreaders respectively. This structural design further enhances the strength and aesthetics of the charger's outer shell. Additionally, the window design on the upper heat spreader provides space for the display screen.
[0012] Preferably, the upper and lower housings are fixedly connected by screws. This connection method is simple and reliable, easy to assemble and disassemble, and also ensures the sealing and stability of the charger housing.
[0013] The advantages of this utility model are:
[0014] 1. By mounting the display screen on the back of the motherboard, the display board component is eliminated, thereby reducing production costs.
[0015] 2. The threaded connection between the upper and lower housings makes the charger assembly and maintenance more convenient and quick.
[0016] 3. The design of the upper and lower vests enhances the strength of the shell and also improves its appearance.
[0017] In summary, the battery charger with the display screen mounted on the back of the motherboard provided by this utility model eliminates the need for a display board, reduces production costs, and has great market application and promotion value. Attached Figure Description
