[0002] A charge controller is a device used to manage the charging and discharging process of a battery to protect the battery and extend its service life. The main functions include:

[0003] 1. Prevent overcharging and over-discharging: When the battery is fully charged, the charge controller will automatically cut off the charging current to prevent the battery from overcharging; similarly, when the battery is too low, it will stop discharging to avoid over-discharging.

[0004] 2. Protect the battery: By maintaining safe voltage and current levels, ensure that the battery operates within a safe operating range, thereby reducing damage and improving safety.

[0005] Small portable charging controllers generate heat during use, but current charging controllers have average heat dissipation effects and are unable to quickly dissipate the internal heat. In addition, existing charging controllers are prone to tipping over, which can easily cause damage to the charging controller. Utility Model Content

DETAILED DESCRIPTION

[0025] See also Figure 1-4 , the embodiments of the utility model are further described;

[0026] A small portable charging controller comprises a housing 1, and a plurality of heat dissipation holes 4 are opened on the top of the housing 1;

[0027] A metal mesh cover 14 surrounding a plurality of heat dissipation holes 4 is detachably connected to the top of the inner wall of the casing 1, a plurality of heat dissipation fins 16 are slidably connected inside the metal mesh cover 14, the upper ends of the plurality of heat dissipation fins 16 extend into the plurality of heat dissipation holes 4 respectively, and a plurality of bristles 18 in contact with the inner walls of the heat dissipation holes 4 are fixed on the outer walls of the heat dissipation fins 16, a connecting rod 17 is fixed between each two adjacent heat dissipation fins 16, and a handle 19 located on the outer side of the casing 1 is fixed to the upper end of one of the heat dissipation fins 16;

[0028] Anti-falling components are fixed on both sides of the exterior of the housing 1 to prevent it from falling over;

[0029] When the controller is working, heat is generated inside the controller, and the heat can be dissipated to the outside through the metal mesh cover 14 and the heat dissipation holes 4 on the housing 1, thereby avoiding heat accumulation inside the controller. The metal mesh cover 14 has a certain dust blocking effect, which can prevent external dust from passing through the heat dissipation holes 4 and falling onto the parts inside the controller. In addition, the metal mesh cover 14 has a good heat conduction effect, and the heat in the controller will be quickly transferred to the metal mesh cover 14, and the metal mesh cover 14 will transfer the heat to the several heat sinks 16 connected thereto, and the several heat sinks 16 will quickly conduct the heat on them to the several heat sinks 16, thereby accelerating the heat dissipation inside the controller.

[0030] like Figure 1-3As shown, after the controller has been used for a period of time, a lot of dust will be stuck on the inner walls of several heat dissipation holes 4. At this time, the user can hold the controller upside down with one hand, and then hold the handle 19 with the other hand and move it. The handle 19 will drive the heat sink 16 connected thereto to move. Since a connecting rod 17 is fixed between each two adjacent heat sinks 16, several connecting rods 17 and several heat sinks 16 form a frame. When the handle 19 moves, it will drive the frame to slide on the metal mesh cover 14. At the same time, the heat sink 16 will drive several bristles 18 thereon to brush the inner walls of the corresponding heat dissipation holes 4, which can avoid clogging of the heat dissipation holes 4. The dust will fall to the ground. The operation is simple, and it is convenient for the user to clean the dust in the heat dissipation holes 4. The heat sink 16, the connecting rod 17 and the bristles 18 are small in size and do not affect the internal heat dissipation of the controller.

[0031] The anti-falling component can prevent the controller from tilting to the side, has an anti-falling effect, and protects the controller. The controller is small in size, which is convenient for users to carry the controller out.

[0032] The anti-falling assembly includes an L-shaped anti-falling side plate 2 and an adsorption member. The anti-falling side plate 2 is fixed below the outer side wall of the housing 1. The adsorption member is installed on the anti-falling side plate 2, and the adsorption end of the adsorption member is flush with the bottom of the anti-falling side plate 2.

[0033] Specifically, Figure 1 As shown, the bottom of the L-shaped anti-tilt side plate 2 extends to the outside of the housing 1, expanding the floor area of ​​the bottom of the housing 1, and preventing the controller from tipping over. The adsorbent can be adsorbed on the wall, desktop, etc., which enhances the stability of the controller at the designated location and further enhances the anti-tilt performance of the controller.

[0034] The adsorption member includes a threaded tube 5, a threaded cap 6, a lower pressing block 7, an elastic member and a suction cup 10. The threaded tube 5 is fixed on the anti-collapse side plate 2 and passes through the bottom thereof. The threaded cap 6 is threadedly connected to the threaded tube 5. The lower pressing block 7 is fixed inside the threaded cap 6 and extends into the threaded tube 5. The elastic member is installed at the bottom of the lower pressing block 7. The suction cup 10 is fixed at the bottom of the elastic member.

[0035] Specifically, when the adsorbent needs to be adsorbed on the desktop, the threaded cap 6 on the threaded tube 5 is screwed downward, and the threaded cap 6 will drive the pressing block 7 to move downward, so that the pressing block 7 presses the elastic member, and the elastic member will undergo elastic deformation and give a downward elastic force to the suction cup 10, causing the air inside the suction cup 10 to be squeezed out, so that the air pressure inside the suction cup 10 is lower than the external air pressure. Therefore, the suction cup 10 will be firmly adsorbed on the desktop, which can effectively prevent the controller from being dragged on the desktop and protect the controller.

[0036] The elastic member includes a tube column 8 and a spring 9. The tube column 8 is slidably connected to the upper end of the outer part of the suction cup 10, and a pair of side ears 11 are fixed to the outer wall of the tube column 8. A thin rope 12 is inserted into the side ears 11. The upper end of the thin rope 12 is fixed to the bottom of the lower pressure block 7, and the lower end of the thin rope 12 is fixed to a limiting ball 13. The spring 9 is fixed in the tube column 8, and the lower end of the spring 9 is fixedly connected to the upper end of the suction cup 10.

[0037] Specifically, Figure 4 As shown, when the pressing block 7 rotates to press the tube column 8, the tube column 8 will squeeze the spring 9 downward, and the spring 9 will give the suction cup 10 a downward elastic force. When the pressing block 7 rotates, it will drive the thin rope 12 to rotate together, and the thin rope 12 will be wrapped around the tube column 8. The length of the thin rope 12 is long enough for the pressing block 7 to move. The side ear 11 plays a positioning role for the thin rope 12. The limiting ball 13 at the lower end of the thin rope 12 can prevent the thin rope 12 from moving out of the side ear 11. When the user moves the controller, the pressing block 7 will drive the thin rope 12, the side ear 11, the tube column 8, the spring 9 and the suction cup 10 to move together.

[0038] A plurality of heat dissipation fins 3 are installed at the bottom of the housing 1;

[0039] The presence of a plurality of heat dissipation fins 3 can quickly conduct the heat in the controller to the outside, thereby enhancing the heat dissipation effect of the controller.

[0040] A circuit board is installed in the housing 1, and a fan 15 electrically connected to the circuit board is fixed at the bottom of the metal mesh cover 14;

[0041] The working interval time of the fan 15 can be set through the circuit board. When the fan 15 is in use, it can blow the air flow inside the controller to accelerate the heat dissipation to the outside.
