[0002] To ensure the safe and stable use of lithium-ion batteries, a battery protection board is usually configured for them. The battery protection board can protect lithium-ion batteries from overcharging, over-discharging, and other situations. When these situations occur, the battery protection board can cut off the power supply circuit in time to achieve protection.

[0003] Current battery protection boards mainly consist of a base plate and a circuit board. The circuit board is fixed to the base plate with bolts and spaced apart from it. One end of the bolts and the pins of the circuit components on the circuit board are exposed. When the battery protection board is damaged, it is not easy to replace. In addition, traditional battery protection boards are directly fixed to the base plate with bolts, making them susceptible to impact and damage during battery replacement and maintenance.

A guide rail 105 is provided on the upper surface of the protective plate support 104. A support plate 108 is slidably connected within the guide rail 105. The protective plate 101 is installed between the two support plates 108. A connecting plate 106 is provided on the support plate 108, and the connecting plate 106 is fixedly connected to the two support plates 108. An interface 107 is fixedly connected to the connecting plate 106, and the interface 107 matches the baffle 101. A rack is provided on the side wall of the support plate 108. A first transmission shaft 109 is rotatably connected to the upper wall of the baffle 102. A torsion spring is provided on the first transmission shaft 109, and both ends of the torsion spring are respectively fixedly connected to the first transmission shaft 109. A transmission shaft 109 and a baffle 102 are connected. A gear 201 and a first bevel gear 202 are fixedly connected to the first transmission shaft 109. The gear 201 meshes with a rack. A second transmission shaft 203, a cover-opening shaft 205, a first steering shaft 206, and a second steering shaft 207 are rotatably connected to the side wall of the baffle 102. Two second bevel gears 204 are fixedly connected to the second transmission shaft 203. The second bevel gears 204 correspond one-to-one with the first bevel gears 202 and mesh with each other. A belt 208 is sleeved in the middle section of the second transmission shaft 203. The end of the belt 208 away from the second transmission shaft 203 is sleeved on the cover-opening shaft 205 through the first steering shaft 206 and the second steering shaft 207. An upper cover plate 103 is fixedly connected to the cover-opening shaft 205.

[0014] Specifically, a limiting groove 209 is fixedly connected to the upper surface of the baffle 102, a slide rod 301 is fixedly connected inside the limiting groove 209, a limiting slider 302 is interactively connected to the slide rod 301, a spring 303 is sleeved on the slide rod 301, and the two ends of the spring 303 are respectively fixedly connected to the inner wall of the limiting groove 209 and the limiting slider 302. A limiting groove 304 is provided at the top of the limiting groove 209, and a paddle is fixedly connected to the upper end of the limiting slider 302. The paddle is slidably connected inside the limiting groove 304, and the limiting slider 302 matches the upper cover plate 103.

[0015] Specifically, the upper cover plate 103 is matched with the two side baffles 102, and the second transmission shaft 203, the cover opening shaft 205, the first steering shaft 206, and the second steering shaft 207 are all provided with slots, and the belt 208 is specifically confined within the slots.

[0016] Specifically, the rack on the pallet 108 has anti-disengagement openings at both ends, which are matched with the gear 201.

[0017] Working principle: When the user needs to install the protective plate 101, the protective plate 101 is placed between the two support plates 108. The protective plate 101 is then pushed inwards, causing the support plates 108 to slide inwards along the guide rail 105. At this time, the rack on the side wall of the support plate 108 drives the gear 201 to rotate, which in turn drives the first bevel gear 202 to rotate. The first bevel gear 202 then drives the second bevel gear 204 to rotate. Simultaneously, the second transmission shaft 203 rotates clockwise. The second transmission shaft 203 is connected to the belt 20... 8 drives the opening shaft 205 to rotate clockwise. The rotation of the opening shaft 205 causes the upper cover plate 103 fixed on the opening shaft 205 to close clockwise along the opening shaft 205. When the upper cover plate 103 is about to close, the limit slider 302 in the limit slot 209 is engaged, so that the upper cover plate 103 is level with the baffle 102. The limit slider 302 is released. At this time, the limit slider 302 is engaged on the upper surface of the upper cover plate 103 under the action of the spring 303. At this time, the protective plate 101 is installed. When the user needs to remove the protective plate 101, simply press the limit slider 302. At this time, the first transmission shaft 109 will automatically rotate under the action of the torsion spring, causing the rack on the support plate 108 to pop out. At the same time, it will cause the second bevel gear 204 on the second transmission shaft 203 to rotate counterclockwise. That is, the second transmission shaft 203 will rotate counterclockwise. At this time, the cover opening shaft 205 will rotate counterclockwise under the action of the belt 208. That is, the upper cover plate 103 will rotate and open along the cover opening shaft 205. At the same time, as the support plate 108 pops out, the protective plate 101 installed between the two support plates 108 will separate from the interface 107 and exit the device. At this time, the user can remove the protective plate 101 from between the two support plates 108.

[0018] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
