Description

Technical Field

[0001] The utility model relates to the technical field of switch power supply protection, in particular to a switch power supply protection cover. Background Art

[0002] The input of the power supply is mostly AC power, such as the mains, or DC power, and the output is mostly devices that require DC power, such as personal computers. The switching power supply converts the voltage and current between the two. Household electricity is also connected and disconnected through the power switch. With the development of society and the popularization of electricity, cities, streets and families are inseparable from the demand for electricity. Therefore, the protection of the power supply is becoming more and more important.

[0003] Most of the existing power supply protective covers can only prevent direct external impact on the switching power supply body. However, since there are a large number of welded capacitors and other electronic components on the switching power supply body, it is easy to cause the electronic components to be desoldered from the circuit board during the collision, thereby affecting the normal use of the switching power supply body. In addition, when the device is connected to the switching power supply body, the switching power supply body will generate heat during operation. Most of the existing power supply protective covers have the problem of difficult heat dissipation. When the temperature inside the protective cover is too high, it may affect the normal use of the electrical appliance. In view of this, we propose a safety protective cover and power supply for the switching power supply. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art that electronic components and circuit boards may easily become desoldered during a collision, thereby affecting the normal use of the switching power supply body, and that the temperature inside the protective cover may be too high, which may affect the normal use of the electrical appliance, the present application provides a switching power supply protective cover.

[0005] The present application provides a switching power supply protective cover, which adopts the following technical solution:

[0006] A switch power supply protective cover comprises a protective box and a cover plate, wherein a buffer component for protecting the switch power supply body is arranged inside the protective box, wherein the buffer component comprises a base, wherein a sliding rod is vertically arranged on the base, a mounting plate is slidably sleeved on the sliding rod, a plurality of legs are evenly arranged on the mounting plate, the legs are connected to the switch power supply body by mounting screws, a plurality of buffer springs are evenly arranged between the mounting plate and the base, one end of the buffer spring is connected to the base, and the other end is connected to the mounting plate, the cover plate is arranged on the top of the protective box by fixing screws, an auxiliary buffer component is arranged at the bottom of the cover plate, a plurality of ventilation holes are respectively provided on two opposite surfaces of the protective box, a support frame is arranged at one end inside the protective box, a fan is rotatably arranged on the support frame, a driving motor is also arranged on the support frame, and the output shaft of the driving motor is coaxially connected to the fan, a filter frame is arranged outside the protective box, a filter plate is arranged on the filter frame, the filter plate is directly opposite to the ventilation hole, and a sealing component for closing the ventilation hole is arranged inside the protective box.

[0007] By adopting the above technical solution, the protective box can protect the switching power supply body and to a certain extent prevent the switching power supply body from being damaged due to collisions between the switching power supply body and the inner wall of the protective box caused by external shaking or collisions. The filter plate can filter the air entering the protective box, thereby reducing the entry of impurities and dust into the interior. The sealing component can close and seal the ventilation holes when the switching power supply body is not in use, thereby further reducing the entry of impurities and dust into the interior and improving the overall waterproof effect of the protective box.

[0008] Optionally, the auxiliary buffer assembly includes a plurality of mounting rods, the plurality of mounting rods are evenly arranged at the bottom of the cover plate along the vertical direction, and the plurality of mounting rods correspond one-to-one to a plurality of supporting feet, an auxiliary spring is arranged at the bottom of the mounting rod, a flexible rubber block is arranged at one end of the auxiliary spring away from the mounting rod, and the flexible rubber block abuts against the switching power supply body.

[0009] By adopting the above technical solution, the switching power supply body is installed on the support leg. When the protective box is subjected to external impact, under the action of multiple buffer springs, the mounting plate will reciprocate along the length direction of the sliding rod, and at the same time will push the flexible rubber block to move. Under the action of the auxiliary spring, the buffer spring and the auxiliary spring will absorb the impact force, thereby enabling the switching power supply body to be stably installed on the support leg for operation.

[0010] Optionally, the sealing assembly includes a sealing plate, a placement groove for placing the sealing plate is provided at the top of the ventilation hole, an installation groove is provided at the bottom of the ventilation hole, the sealing plate is slidably arranged in the placement groove, sliding seats are slidably arranged at both ends of the ventilation hole on the protective box, the protective box is provided with sliding grooves for facilitating the sliding of the sliding seats, the two ends of the sealing plate are respectively connected to two sliding seats, and the protective box is provided with a driving assembly for driving the sliding seats to slide.

[0011] By adopting the above technical solution, when the switching power supply body is supplying power, it will generate a lot of heat. At this time, the driving component pushes the sliding seat to move along the length direction of the sliding groove, thereby driving the sealing plate to move as a whole into the placement groove, so that air can flow through the ventilation holes, and then start the driving motor. The driving motor will drive the fan to rotate during the rotation of the driving motor, thereby accelerating the entry of air and outflowing from the ventilation holes on the protective box away from the fan, thereby cooling the switching power supply body. When the switching power supply stops working, the driving component moves the sliding seat in the opposite direction, so that the bottom of the sealing plate moves into the installation groove, and the top of the sealing plate is still located in the placement groove, thereby sealing the ventilation holes, making it difficult for external dust and impurities to enter the interior of the protective box.

[0012] Optionally, the driving assembly includes a permanent magnet, a connecting rod is provided on the top of the two sliding seats, the permanent magnet is provided on the connecting rod, and an electromagnet is provided on the protective box, and the electromagnet is located directly above the permanent magnet.

[0013] By adopting the above technical solution, when the sealing plate needs to be completely located in the placement groove, the electromagnet is energized and will generate magnetism opposite to that of the permanent magnet. Since opposite poles of magnets attract each other, the electromagnet will absorb the permanent magnet, and the movement of the permanent magnet will drive the sliding seat to move along the length direction of the sliding groove.

[0014] Optionally, a return spring is provided at the bottom of the sliding seat, one end of the return spring is connected to the bottom of the sliding seat, and the other end of the return spring is connected to the groove wall of the sliding groove.

[0015] By adopting the above technical solution, when the electromagnet is energized, the sliding seat will move in the direction close to the electromagnet, and the reset spring will be stretched. When the switching power supply body stops working, the electromagnet is de-energized. Under the action of the gravity of the sliding seat and the sealing plate itself and the elastic force of the reset spring, the bottom of the sealing plate will fall into the installation groove, thereby achieving sealing of the ventilation hole.

[0016] Optionally, sealing strips are provided around the sealing plate.

[0017] By adopting the above technical solution, the sealing strip can enhance the sealing effect of the sealing plate on the ventilation hole.

[0018] Optionally, a sealing groove is provided on the cover plate, the top of the protection box is arranged in the sealing groove, and a sealing gasket is arranged in the sealing groove.

[0019] By adopting the above technical solution, the cover plate and the protective box are detachably connected, and the sealing gasket can improve the sealing between the cover plate and the protective box, reducing the possibility of external dust and impurities entering the interior of the protective box.

[0020] Optionally, a transparent acrylic plate is provided on one side surface of the protective box.

[0021] By adopting the above technical solution, the staff can observe the specific working status of the switching power supply body inside the protective box through the transparent acrylic plate, thereby facilitating the staff to determine whether the switching power supply body needs to be repaired.

[0022] The utility model has the following advantages:
