[0035] Reference Figures 1 to 5 As shown, a transformer device according to one embodiment of the present invention includes a frame and a transformer assembly 500.

[0036] Reference Figure 1 , Figure 2 and Figure 3As shown, specifically, the frame includes a housing 100, a mounting plate 200, and a cover plate 300. Specifically, the following explanation uses the length direction of the housing 100 as the vertical direction, the width direction as the horizontal direction, and the thickness direction as the front-back direction. The housing 100 has a receiving cavity 110, which can be used to house components such as the mounting plate 200, transformer assembly 500, and control assembly 700, thereby reducing the risk of damage to these components from external factors. The receiving cavity 110 has a forward-facing opening. The cover plate 300 is rotatably connected to the housing 100. By rotating the cover plate 300 relative to the housing 100 in either the forward or reverse direction, the opening of the receiving cavity 110 can be opened or closed. The opening can serve as an inlet or outlet for the receiving cavity 110, allowing the transformer assembly 500 and the mounting plate 200 to pass through and exit the receiving cavity 110.

[0037] Reference Figure 1 , Figure 2 and Figure 3 As shown, the transformer assembly 500 is disposed in the accommodating cavity 110. The transformer assembly 500 includes a bracket 520, an iron core 510 and a winding. The bracket 520 is connected to the mounting plate 200, the iron core 510 is connected to the bracket 520, and the winding is connected around the iron core 510. That is, the mounting plate 200 can provide support for the transformer assembly 500.

[0038] Reference Figure 1 , Figure 2 and Figure 3 As shown, the mounting plate 200 is disposed in the accommodating cavity 110. The mounting plate 200 can be attached to the upper part of the rear wall of the accommodating cavity 110 and detachably connected to the housing 100. The back of the housing 100 is provided with a first hook hole 120 communicating with the accommodating cavity 110. The mounting plate 200 is provided with a second hook hole 210 opposite to the first hook hole 120. This transformer can be applied to the wall mounting method. The column connected to the wall can pass through the first hook hole 120 and the second hook hole 210, thereby realizing the hooking of the mounting plate 200 and the column, so as to assist in the wall mounting installation of the transformer.

[0039] Reference Figure 1 , Figure 2 and Figure 3 As shown, the transformer can also be installed in a wall-mounted manner, that is, the housing 100 can be embedded in the wall. When the transformer assembly 500 needs to be repaired or replaced, the user can separate the mounting plate 200 from the housing 100, so that the mounting plate 200 and the transformer assembly 500 can be passed through the outlet and taken out of the receiving cavity 110 together without damaging the connection structure between the housing 100 and the wall.

[0040] Reference Figure 1 , Figure 2 and Figure 3 As shown, this transformer is suitable for both wall-mounted and wall-embedded applications, thus improving its applicability to various usage scenarios.

[0041] Reference Figure 2 , Figure 4 and Figure 5 As shown, it can be understood that the iron core 510 is arranged in a ring shape, and the inner circumferential surface of the iron core 510 is fixedly connected to the bracket 520. The transformer also includes a first connector 600. The bracket 520 is provided with a first mounting hole 521. Correspondingly, the mounting plate 200 is provided with a second mounting hole 220. The connector passes through the first mounting hole 521 and the second mounting hole 220 to realize the detachable connection between the bracket 520 and the mounting plate 200.

[0042] Reference Figure 2 , Figure 4 and Figure 5 As shown, specifically, in order to further increase the connection stability between the bracket 520 and the mounting plate 200, multiple first mounting holes 521 are provided. The multiple first mounting holes 521 are arranged circumferentially around the central axis of the iron core 510. Specifically, four first mounting holes 521 are provided, and the central angles of two adjacent first mounting holes 521 are 90 degrees.

[0043] Reference Figure 2 , Figure 4 and Figure 5 As shown, multiple second mounting holes 220 are provided, and the first mounting holes 521 are provided one-to-one with the second mounting holes 220. Four first connectors 600 are provided, and each first connector 600 is connected to a set of first mounting holes 521 and second mounting holes 220. The transformer equipment can improve the connection stability between the mounting plate 200 and the bracket 520 through multiple first connectors 600, so as to achieve a stable connection between the mounting plate 200 and the bracket 520.

[0044] Reference Figure 2 , Figure 4 and Figure 5 As shown, specifically, the first connector 600 includes a first bolt and a first nut. The first bolt passes through the first mounting hole 521 and the second mounting hole 220 and is threadedly connected to the first nut. By screwing the first bolt and the first nut together, the mounting plate 200 and the bracket 520 can be tightly connected as one unit. The connection between the mounting plate 200 and the bracket 520 is achieved through multiple first connectors 600, which can effectively limit the rotation and shaking of the bracket 520 relative to the mounting plate 200, thereby improving the connection stability between the bracket 520 and the mounting plate 200.

[0045] Understandably, in order to avoid the obstruction of the housing 100 to the connection between the first connector 600 and the mounting plate 200 and the bracket 520, the back of the housing 100 is also provided with a notch 160 communicating with the accommodating cavity 110. Multiple second mounting holes 220 are opposite to the notch 160. The notch 160 is provided to avoid the head of the first connector 600, so that the mounting plate 200 can be tightly attached to the rear wall of the accommodating cavity 110 of the housing 100, which helps to improve the connection stability between the mounting plate 200 and the housing 100.

[0046] Reference Figure 2 , Figure 4 and Figure 5 As shown, it can be understood that the transformer also includes a second connector, a third mounting hole 130 on the housing 100, and a fourth mounting hole 230 on the mounting plate 200 opposite to the third mounting hole 130. The second connector passes through the third mounting hole 130 and the fourth mounting hole 230, so that the mounting plate 200 is detachably connected to the housing 100.

[0047] Reference Figure 2 , Figure 4 and Figure 5 As shown, specifically, the mounting plate 200 has a fourth mounting hole 230 at each of its four corners. Correspondingly, the housing 100 has a plurality of third mounting holes 130 on the rear surface of the accommodating cavity 110. Each third mounting hole 130 corresponds to a fourth mounting hole 230. The second connector passes through the third mounting hole 130 and the fourth mounting hole 230 to fix the mounting plate 200 and the housing 100. The connection of the multiple second connectors helps to reduce the rotation and shaking of the mounting plate 200 relative to the housing 100, thereby improving the connection stability between the mounting plate 200 and the housing 100.

[0048] Reference Figure 2 , Figure 4 and Figure 5 As shown, specifically, the second connector includes a second bolt and a second nut. The second bolt passes through the third mounting hole 130 and the fourth mounting hole 230 and is threadedly connected to the second nut. By screwing the second bolt and the second nut together, the mounting plate 200 and the housing 100 can be pressed tightly together. The connection between the mounting plate 200 and the housing 100 is achieved through multiple second connectors, which can effectively limit the rotation and shaking of the mounting plate 200 relative to the housing 100, thereby improving the connection stability between the mounting plate 200 and the housing 100.

[0049] Reference Figure 2 , Figure 4 and Figure 5As shown, it can be understood that the left and right edges of the mounting plate 200 can be bent to form a first reinforcing rib and a second reinforcing rib that bend forward. The transformer equipment can be formed by bending the mounting plate 200. By setting the first and second reinforcing ribs, the strength and bending resistance of the mounting plate 200 can be effectively improved.

[0050] Reference Figure 2 , Figure 4 and Figure 5 As shown, it can be understood that the bottom and back of the housing 100 are respectively provided with wiring holes 140 communicating with the accommodating cavity 110. The transformer can select to thread the wire through the wiring hole 140 at the bottom of the housing 100 or the wiring hole 140 at the back of the housing 100 according to different installation scenarios, so that the cable is connected to the transformer assembly 500, thereby improving the applicability of the transformer to different installation scenarios.

[0051] Reference Figure 2 , Figure 4 and Figure 5 As shown, specifically, the wiring hole 140 located on the back of the housing 100 is located at the lower end of the housing 100, and the wiring hole 140 located on the back of the housing 100 is adjacent to the wiring hole 140 located at the bottom of the housing 100, so that the wiring area of ​​the transformer can be centrally controlled.

[0052] Reference Figure 2 , Figure 4 and Figure 5 As shown, it can be understood that the back of the housing 100 is provided with multiple vibration damping pads spaced apart along the plane. The vibration damping pads can be made of materials with good buffering performance, such as rubber pads, silicone pads, etc. After the transformer equipment is installed, the multiple vibration damping pads located on the back of the housing 100 can abut against the mounting plane. By compressing and deforming the vibration damping pads, the installation stability of the transformer equipment can be improved. Moreover, through the deformation of the vibration damping pads, the vibration transmitted from the mounting plane to the housing 100 can be effectively buffered, thereby improving the service life of the components located inside the housing 100.

[0053] Reference Figure 2 , Figure 4 and Figure 5 As shown, it can be understood that both the first hook hole 120 and the second hook hole 210 have a hook portion 211 and an inlet / outlet portion 212 that are connected vertically. The internal size of the inlet / outlet portion 212 is larger than the internal size of the hook portion 211. That is, both the first hook hole 120 and the second hook hole 210 are arranged in a shape that is larger at the bottom and smaller at the top.

[0054] Reference Figure 2 , Figure 4 and Figure 5As shown, when the transformer is installed by wall mounting, the user can align the inlet / outlet 212 of the first mounting hole 120 and the second mounting hole 210 of the housing 100 with the column located on the wall, and apply pressure to the housing 100 toward the wall so that the column passes through the inlet / outlet 212 of the first mounting hole 120 and the second mounting hole 210. Both the inlet / outlet 212 of the first mounting hole 120 and the inlet / outlet 212 of the second mounting hole 210 are larger than the outer diameter of the column to facilitate the movement of the column relative to the housing 100. Under its own weight, the housing 100 moves downward relative to the column located on the wall, causing the column to move from the inlet / outlet 212 of the first mounting hole 120 and the second mounting hole 210 to the mounting part 211. Since the internal size of the mounting part 211 is smaller than the internal size of the inlet / outlet 212, the restrictive effect of the first mounting hole 120 and the second mounting hole 210 on the column can be enhanced. With the cooperation of the external fasteners and the column, the housing 100 can be mounted and fixedly connected to the column, which is beneficial to improving the stability of the transformer installation.

[0055] Specifically, one end of the column that penetrates the housing 100 is provided with a threaded section, and the fastener can be a nut. After the column is inserted into the hooking part 211 of the first hooking hole 120 and the second hooking hole 210, it can be connected to the threaded section by the nut, and the transformer can be hooked to the wall by the abutment of the nut against the inner surface of the housing 100.

[0056] Reference Figure 2 , Figure 4 and Figure 5 As shown, it can be understood that the transformer also includes a control component 700, which is connected to the housing 100 and disposed in the accommodating cavity 110. The control component 700 is electrically connected to the transformer assembly 500 and is configured to detect the resistance value of the transformer assembly 500 and control the operating state of the transformer assembly 500 according to the detected resistance value.

[0057] Reference Figure 2 , Figure 4 and Figure 5 As shown, the control component 700 can determine whether the temperature of the transformer component 500 exceeds the preset temperature by detecting the resistance value of the transformer component 500 based on the relative relationship between the resistance value and temperature of the transformer component 500. When the control component 700 determines that the temperature of the transformer component 500 exceeds the preset temperature, it can control the transformer component 500 to disconnect, thereby improving the safety of the transformer equipment.

[0058] It should be understood that in some other embodiments, the cover plate 300 is provided with multiple vent holes in the area of ​​the transformer assembly 500 to accelerate the heat transfer of the transformer assembly 500 to the outside, thereby improving the heat dissipation performance of the transformer and thus improving the safety of the transformer.

[0059] Reference Figure 2 , Figure 4 and Figure 5 As shown, it is understood that in this embodiment, in order to further improve the compatibility between the housing 100 and the control component 700 and avoid the problem of installation difficulty or inability to install due to the excessive size of the control component 700, the control component 700 of the transformer equipment includes multiple control modules 710 connected to each other.

[0060] Reference Figure 2 , Figure 4 and Figure 5 As shown, the transformer can be modularly configured so that the control component 700 can be divided into multiple interconnectable control modules 710. During manufacturing, multiple control modules 710 can be selected and assembled according to the needs of the actual application scenario to form the control component 700. Furthermore, by connecting the smaller control modules 710 to the housing 100, the lower space of the accommodating cavity 110 can be fully utilized to achieve efficient assembly of the control component 700 and the housing 100.

[0061] Among them, at least two control modules 710 are stacked one after the other, which can make full use of the space in the front-back direction of the accommodating cavity 110 to realize the accommodating of the control component 700 in the accommodating cavity 110.

[0062] Reference Figure 2 , Figure 4 and Figure 5 As shown, it is understood that in order to achieve a quick and detachable connection between the cover plate 300 and the housing 100, the transformer also includes a spring 410 and a pin 420. The upper end of the cover plate 300 is rotatably connected to the upper end of the housing 100, and a mounting seat is provided at the upper end of the cover plate 300. The mounting seat is provided with a first rotating hole 310, and a second rotating hole 150 is provided at the upper end of the side of the housing 100.

[0063] Reference Figure 2 , Figure 4 and Figure 5 As shown, the pin 420 is rotatably connected to the mounting base. The pin 420 can pass through the first rotating hole 310 and the second rotating hole 150 to realize the rotatable connection between the cover plate 300 and the housing 100. The pin 420 is configured to be able to enter and exit the second rotating hole 150. The two ends of the spring 410 are respectively connected to the cover plate 300 and the pin 420 to drive the pin 420 to be inserted into the second rotating hole 150.

[0064] Reference Figure 2 , Figure 4 and Figure 5 As shown, in its natural state, under the elastic action of the spring 410, the spring 410 can drive the pin 420 to be inserted into the second rotating hole 150, that is, to realize the rotational connection between the pin 420 and the first rotating hole 310 and the second rotating hole 150, that is, to realize the rotational connection between the cover plate 300 and the housing 100.

[0065] Reference Figure 2 , Figure 4 and Figure 5 As shown, when it is necessary to separate the cover plate 300 from the housing 100, the user can push the pin 420 to compress the spring 410, causing the pin 420 to exit the second rotating hole 150, thus separating the pin 420 from the second rotating hole 150. This allows the cover plate 300 to be separated from the housing 100 without the need for other tools, simplifying the assembly and disassembly process of the cover plate 300 and the housing 100, making the assembly and disassembly of the transformer equipment simpler and more convenient.

[0066] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments.
