Description

Technical Field

[0001] This utility model relates to the field of magnetic power supplies, specifically a magnetic constant voltage power supply. Background Technology

[0002] A constant voltage power supply is a power supply device that can maintain a constant output voltage. Its core characteristic is that its output voltage can be maintained at a preset constant value regardless of changes in the load. This type of power supply uses a complex internal circuit design and feedback mechanism to detect the output voltage in real time and adjust the output current as needed to ensure voltage stability.

[0003] Most existing constant voltage power supplies are used for LED lights, using stable voltage to ensure the brightness and lifespan of the lights. However, during installation and use, the temperature of the constant voltage power supply will rise when the current is large. This can easily lead to damage to the components and affect the lifespan of electronic equipment. There is still room for improvement in its structure. Utility Model Content

[0018] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0019] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two entities connected are not linked by an intermediate structure but are connected as a whole through a transmission structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0021] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a magnetic constant voltage power supply, including a power supply body 1, the power supply body 1 including a protective cover plate 2, a transformer structure 3 and a magnetic base plate 4, the transformer structure 3 is slidably connected to the outside of the magnetic base plate 4, and the magnetic base plate 4 is fixed to the bottom end of the transformer structure 3.

[0023] The protective cover 2 of this constant voltage power supply has a hollow design, which greatly improves the overall heat dissipation effect. In addition, the protective cover 2 has a left and right sliding installation design, which facilitates subsequent disassembly, maintenance and dust cleaning, thus improving its practicality.

[0024] The protective cover 2 includes a cover body 21, heat dissipation holes 22 and limiting and fixing plates 23. The heat dissipation holes 22 are provided in two sets and symmetrically arranged on both sides of the top of the cover body 21. The limiting and fixing plates 23 are provided in two sets and symmetrically arranged at the bottom of both ends of the cover body 21.

[0025] The heat dissipation holes 22 have a large-area hollow design, which allows the heat generated by the transformer structure 3 to be quickly conducted upward and dissipated.

[0026] The transformer structure 3 includes a circuit board 31, an input terminal 32, an electromagnet 33, a resistor 34, and an output terminal 35. The input terminal 32 is inserted and fixed on one side of the top of the circuit board 31, and the output terminal 35 is inserted and fixed on the other side of the top of the circuit board 31. The electromagnet 33 is fixed on the top of the circuit board 31. Several groups of resistors 34 are evenly arranged on the top of the circuit board 31. The electromagnet 33 and the resistors 34 are electrically connected to the input terminal 32 and the output terminal 35 through the circuit board 31.

[0027] In use, one end of the input cable is fixed to the input terminal 32. After being transformed by the resistor 34, the voltage is transmitted outward through the output terminal 35. The two sets of limiting and fixing plates 23 of the protective cover plate 2 cover the input terminal 32 and the output terminal 35 of the transformer structure 3 respectively, effectively conducting the heat generated at the input terminal 32 and the output terminal 35 to the cover plate body 21. The cover plate body 21 is made of metal, which can quickly conduct heat out. Combined with the heat dissipation holes 22, the heat dissipation efficiency is effectively improved.

[0028] The magnetic base plate 4 includes a limiting side plate 41 and a base plate body 42, with the limiting side plate 41 symmetrically fixed on both sides of the base plate body 42;

[0029] During installation, the base plate body 42 is magnetically fixed inside the LED light group for installation. The magnetic adsorption design reduces the risk of falling and makes the installation position more flexible, which can be adjusted according to actual needs.

[0030] A sliding groove is provided on the top outer side of the limiting side plate 41, and a bent protrusion is fixed on the outer side of the cover plate body 21. The sliding connection between the protective cover plate 2 and the magnetic bottom plate 4 is achieved by the sliding of the bent protrusion in the sliding groove.

[0031] The sliding protective cover 2 is easier to disassemble during maintenance. The heat dissipation holes 22 of the protective cover 2 will accumulate dust over time, and the sliding disassembly method is more conducive to dust cleaning. At the same time, since the protective cover 2 and the limiting side plate 41 are also made of iron metal, the magnetic base plate 4 can magnetically attract the protective cover 2 through the limiting side plate 41 to prevent the protective cover 2 from slipping off during installation.

[0032] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention includes the claims being limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0033] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
