[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1 to 3 As shown, a replaceable button battery structure for a computer motherboard includes a PCB board 1, mounting holes 2, a negative electrode groove 3, a welding groove 4, a positive electrode 5, electrode feet 6, a limiting plate 7, a limiting hole 8, and a battery compartment 9. Mounting holes 2 are distributed at the four corners of the top and bottom ends of the PCB board 1. The negative electrode groove 3 is mounted at the top center of the PCB board 1. The welding grooves 4 are respectively opened on the left and right sides of the negative electrode groove 3. The positive electrode 5 corresponds to the upper side of the negative electrode groove 3. The electrode feet 6 are respectively mounted at the left and right ends of the positive electrode 5, and the positive electrode 5 is welded to the welding groove 4 through the electrode feet 6. The limiting plate 7 is fixed to the front side of the left and right electrode feet 6, and the limiting hole 8 is opened in the middle of the limiting plate 7. The battery compartment 9 is installed between the positive electrode 5 and the negative electrode groove 3.

[0017] The battery compartment 9 includes a fixing strip 10, a mounting plate 11, a battery placement slot 12, a buckle slot 13, a movable slot 14, and a limiting buckle 15. The mounting plate 11 is fixed to the rear end of the fixing strip 10, and the mounting plate 11 corresponds to the space between the positive electrode plate 5 and the negative electrode slot 3 of the battery. The mounting plate 11 is slidably connected between the left and right limiting plates 7. The battery placement slot 12 is opened in the middle of the mounting plate 11. The buckle slot 13 is opened on the rear side of the battery placement slot 12. The movable slot 14 is opened on the front left and right sides of the fixing strip 10 and the mounting plate 11, respectively. The limiting buckle 15 is fixed to the front of the left and right ends of the mounting plate 11, and the limiting buckle 15 corresponds to the limiting hole 8.

[0018] The limiting buckle 15 enters or exits the limiting hole 8 by pressing the mounting plate 11 into the movable groove 14.

[0019] The working principle of this utility model is as follows: The PCB board 1 is fixed to the chassis heat sink through the mounting holes 2 with screws, ensuring structural stability. It is then connected to the chassis motherboard via wire soldering to form a battery power supply path. The battery compartment 9 houses the battery, which is placed in the mounting plate 11 through the battery placement slot 12 or removed through the snap-fit ​​slot 13. The battery compartment 9 is inserted between the positive electrode plate 5 and the negative electrode slot 3 through the battery slot inlet on the chassis shell, connecting the battery to the circuit of the PCB board 1.
