[0043] In this embodiment, the first PCBA board 300 is the main controller, which controls the LCD screen display and other functional circuits. The second PCBA board 400 is used to solder the external wiring terminal 410 and the USB charging module. The PCBA board is divided into two parts, which is beneficial for layout. Furthermore, the second PCBA board 400 is connected to the external wiring terminal 410, which requires soldering. The USB power circuit will have a high temperature when charging, which will not affect the main controller.

[0044] In some embodiments, refer to Figure 5 A locking element 500 is fixed to the bottom of the housing 100, and the locking element 500 is used to lock it to the bicycle frame.

[0045] Specifically, the locking component 500 includes a base 510, which is fixed to the bottom of the housing 100 by screws. The base 510 has symmetrically arranged slots 511 on its left and right sides. Each slot 511 has an arc-shaped groove at its lower part, and each slot 511 has a clamp 520 fixed to its lower end by screws. In this embodiment, the base 510 of the locking component 500 is fixed to the bottom of the housing 100 by screws. When the display instrument is fixed to the frame, the two slots 511 on the base 510 can be locked to the handlebars of the frame using the clamps 520, thus achieving a fixed installation of the display instrument.
