Description

Technical Field

[0001] This utility model relates to the field of charger technology, specifically a charger that facilitates heat dissipation. Background Technology

[0002] A charger is a device used to charge batteries. It is widely used in various fields, including personal electronic devices, portable electronic products, power tools, home appliances, electric vehicles and energy storage systems, industrial production, and emergency lighting. Chargers use a microprocessor (CPU chip) as the processing and control center, controlling the operation of the UPS (Uninterruptible Power Supply) through software programs, thus significantly reducing size and weight and lowering manufacturing costs. It typically includes a three-stage intelligent charging method: constant current, constant voltage, and low constant current, to ensure the safety and efficiency of battery charging.

[0003] Most current heat dissipation measures for chargers rely on the wind generated around the casing during normal use to dissipate heat. However, since the wind force cannot be controlled, the internal heat is still difficult to dissipate when the wind force is low, resulting in unstable heat dissipation. Utility Model Content

[0004] The purpose of this invention is to provide a charger that facilitates heat dissipation, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a charger with convenient heat dissipation, comprising a charger housing, square slots on both sides of the charger housing, multiple ventilation holes on one side wall of each of the two square slots, electric cylinders fixedly connected inside each of the two square slots, driven rods fixedly connected to the telescopic ends of each of the two electric cylinders, connecting rods rotatably connected to both ends of each of the two driven rods, heat dissipation plates rotatably connected to the other ends of each of the four connecting rods, the top ends of the two heat dissipation plates rotatably connected to the two sides of the charger housing, fans fixedly connected to the two side walls of the charger housing at the ventilation holes, and a booster device fixedly connected inside the charger housing.

[0006] As a further preferred embodiment of this technical solution, a shock-absorbing seat is provided at the bottom of the charger housing. A damper is fixedly connected inside the shock-absorbing seat and at its center. A first-order shock-absorbing spring is sleeved on the outer surface of the damper. A mounting plate is fixedly connected to the top of the damper. Sliding rods are fixedly connected to the bottom of the mounting plate near the four corners. A second-order shock-absorbing spring is sleeved on the outer surface of each of the four sliding rods. A slider is slidably connected to the outer surface of each of the four sliding rods. A support rod is rotatably connected to the bottom of each of the four sliders. The other end of each of the four support rods is rotatably connected to the bottom surface inside the shock-absorbing seat. The top of the mounting plate is fixedly connected to the bottom of the charger housing.

[0007] As a further preferred embodiment of this technical solution, a positioning groove is provided on the inner surface of the shock absorber seat, and the outer surface of the mounting plate is slidably connected to the inner surface of the positioning groove.

[0008] As a further preferred embodiment of this technical solution, a limiting frame is fixedly connected to the top of the shock absorber seat, and the bottom end of the limiting frame contacts the top end of the mounting plate.

[0009] As a further preferred embodiment of this technical solution, multiple ventilation holes are provided through one side of each of the two heat sinks, and a rain cover is fixedly connected to one side of the heat sink at the location of the multiple ventilation holes.

[0010] As a further preferred embodiment of this technical solution, two positioning posts are fixedly connected to the top and bottom of the two square grooves, and the outer surfaces of the four positioning posts are slidably connected to the interior of the two driven rods.

[0011] As a further preferred embodiment of this technical solution, each of the multiple air vents is fitted with a filter cover.

[0012] This utility model provides a charger that facilitates heat dissipation, and has the following beneficial effects:

[0013] (1) This utility model uses two electric cylinders to push the driven rod to move, thereby driving the two connecting rods to support and open the two heat dissipation plates, thereby increasing the ventilation area inside the charger housing when the wind is small, allowing the fan to send more air into the charger housing and improve the heat dissipation effect. When it rains, the two electric cylinders retract, causing the two heat dissipation plates to retract and seal the square groove, and the heat dissipation gas flows out from the ventilation hole. While improving the waterproof effect, it also has a good heat dissipation effect, thereby improving the heat dissipation effect of the charger housing. The structure is simple, easy to adjust, and has high heat dissipation efficiency.

[0014] (2) This utility model uses the contraction of the damper to cause the No. 1 shock-absorbing spring to contract. During the contraction process, the four support rods are subjected to pressure and rotate, and push the four sliders to move on the slide rods respectively. During the movement, the No. 2 shock-absorbing spring is compressed, which greatly reduces the vibration of the charger housing fixed on the mounting plate. This makes the booster device have a shock-absorbing effect during operation, reducing the mechanical damage caused by vibration to the booster device. Furthermore, the stability of the booster device during the shock-absorbing process is improved by the cooperation of the four return springs and the connecting rod. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1-3 As shown in this embodiment, a charger with convenient heat dissipation includes a charger housing 1. Square slots 2 are provided on both sides of the charger housing 1. Multiple ventilation holes 3 are provided on one side wall of each of the two square slots 2. Electric cylinders 4 are fixedly connected inside each of the two square slots 2. Driven rods 5 are fixedly connected to the extension ends of each of the two electric cylinders 4. Connecting rods 6 are rotatably connected to both ends of each of the two driven rods 5. Heat dissipation plates 7 are rotatably connected to the other ends of each of the four connecting rods 6. The top ends of the two heat dissipation plates 7 are rotatably connected to both sides of the charger housing 1. Fans 10 are fixedly connected to both sides of the charger housing 1 and at the ventilation holes 3. A booster device 12 is fixedly connected inside the charger housing 1. By providing ventilation holes 3, air can enter the charger housing 1. By providing fans 10, air can be blown in. One fan 10 can send outside air into the charger housing 1, and the other fan 10 can send out hot air from inside the charger housing 1.

[0022] like Figure 1 and Figure 4As shown, a shock-absorbing seat 14 is provided at the bottom of the charger housing 1. A damper 15 is fixedly connected inside the shock-absorbing seat 14 and at its center. A first shock-absorbing spring 16 is sleeved on the outer surface of the damper 15. A mounting plate 21 is fixedly connected to the top of the damper 15. Slide rods 19 are fixedly connected to the bottom of the mounting plate 21 near the four corners. Second shock-absorbing springs 20 are sleeved on the outer surface of each of the four slide rods 19. Sliding blocks 18 are slidably connected to the outer surface of each of the four slide rods 19. Support rods 17 are rotatably connected to the bottom of each of the four sliding blocks 18. The other end of each of the four support rods 17 is rotatably connected to the inner bottom surface of the shock-absorbing seat 14. The top of the mounting plate 21 is fixedly connected to the bottom of the charger housing 1. By setting the support rods 17, slide rods 19 and second shock-absorbing springs 20, the movement of the mounting plate 21 can be made more stable, thus improving stability.

[0023] like Figure 4 As shown, a positioning groove 22 is provided on the inner surface of the shock absorber 14, and the outer surface of the mounting plate 21 is slidably connected to the inner surface of the positioning groove 22 to improve the stability of the mounting plate 21 during movement and prevent tilting.

[0024] like Figure 4 As shown, a limiting frame 23 is fixedly connected to the top of the shock absorber seat 14. The bottom end of the limiting frame 23 contacts the top end of the mounting plate 21, which can limit the mounting plate 21 and prevent it from falling off the shock absorber seat 14.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, multiple ventilation holes 8 are provided on one side of each of the two heat sinks 7. A rain cover 9 is fixedly connected to one side of the heat sink 7 at the location of the multiple ventilation holes 8, which can provide heat dissipation when the heat sink 7 is closed.

[0026] like Figure 2 and Figure 3 As shown, two positioning posts 13 are fixedly connected to the top and bottom of the two square grooves 2. The outer surfaces of the four positioning posts 13 are slidably connected to the interior of the two driven rods 5, which can position the driven rods 5 and improve stability.

[0027] like Figure 3 As shown, each of the multiple ventilation holes 3 has a filter cover 11 inserted inside, which can filter the flowing air and prevent dust and other impurities from entering the charger housing 1.

[0028] This utility model provides a charger that facilitates heat dissipation, and its specific working principle is as follows:

[0029] When the outside wind is weak, the driven rod 5 is moved by the two electric cylinders 4, which in turn drives the two connecting rods 6 to support and open the two heat dissipation plates 7. This increases the ventilation area inside the charger housing 1 when the wind is weak, allowing the fan 10 to send more air into the charger housing 1 and improve the heat dissipation effect. When it rains, the two electric cylinders 4 retract, causing the two heat dissipation plates 7 to retract and seal the square groove 2. Gas can flow out from the vent 8. In rainy weather, this not only improves the waterproof effect but also provides good heat dissipation. During the operation of the booster device 12, the damper 15 retracts, causing the first shock-absorbing spring 16 to retract as well. During the retraction process, the four support rods 17 are subjected to pressure and rotate, pushing the four sliders 18 to move on the slide rod 19. During the movement, the second shock-absorbing spring 20 is compressed, which greatly reduces the vibration of the charger housing 1 fixed on the mounting plate 21. This gives the booster device 12 a shock-absorbing effect during operation.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
