Description

Technical Field

[0001] The utility model relates to the technical field of frequency converters, and particularly relates to an integrated frequency conversion component. Background Art

[0002] A frequency converter is a power control device, commonly used in devices such as fans, water pumps, and motors, to control the output power or speed of the device by changing the frequency of the working power supply. The frequency converter is usually integrated into the device housing for easy adjustment and control of the device. As Figure 1 shown, the common integration method of the existing frequency converter is external, that is, the frequency converter is directly integrated outside the device housing. Since the frequency converter is integrated with the device housing, it is very inconvenient to install, wire, repair, and replace the frequency converter as it requires the disassembly of the device housing. In addition, when the frequency converter protrudes outside the device housing, it is extremely easy to be collided during transportation and use, resulting in damage to the electronic components of the frequency converter and making the device inoperable. Content of the Utility Model

[0003] To solve the technical problems existing in the above background art, the utility model provides an integrated frequency conversion component.

[0004] The technical solution of the utility model is as follows:

[0005] An integrated frequency conversion component includes a device housing, a frequency converter, and a mounting bracket;

[0006] A through hole is provided on the device housing for the frequency converter to be inserted into the device housing, and a counterbore is provided around the through hole, and the mounting bracket is installed on the counterbore;

[0007] The four edges of the mounting bracket are in contact with the counterbore. A number of first mounting holes are provided on the mounting bracket, and the number of first mounting holes are arranged at intervals along the edge of the mounting bracket. Corresponding to the positions of the number of first mounting holes, a number of second mounting holes are provided on the counterbore. The mounting bracket is detachably installed on the counterbore by bolts passing through the first mounting holes and being in threaded cooperation with the second mounting holes;

[0008] One end of the frequency converter is connected to the mounting bracket, and the other end passes through the through hole and is inserted into the device housing.

[0009] The frequency conversion component of this application integrates the frequency converter inside the device housing to avoid damage caused by collision. In addition, through the cooperation of the mounting bracket, the counterbore, and the through hole, the frequency converter is detachably installed on the device housing, enabling the frequency converter to be pre-wired outside the device housing and then inserted into the device housing for installation. When the frequency converter needs to be repaired or replaced, the frequency converter can also be directly disassembled and taken out, facilitating the wiring and repair of the frequency converter.

[0010] Preferably, the outer contour of the mounting bracket matches the outer contour of the counterbore, so that when the mounting bracket is installed on the counterbore, the mounting bracket can be embedded into the corresponding counterbore of the counterbore and is clamped with the counterbore, which not only positions the mounting bracket but also strengthens the fixation of the mounting bracket.

[0011] Preferably, the contour of the through hole matches the corresponding contour of the frequency converter, so that when the frequency converter is inserted into the through hole, the through hole positions the frequency converter and at the same time supports the frequency converter.

[0012] In this application, the frequency converter is in the shape of a rectangular body, the mounting bracket is a rectangular plate, and the contours of the counterbore and the through hole are both rectangular.

[0013] Preferably, the widths of the counterbores around the through hole are the same to provide the same installation area and the same support effect.

[0014] Further, the depth of the counterbore is the same as the thickness of the mounting bracket, so that when the mounting bracket is installed on the counterbore, the outer surface of the mounting bracket is flush with the outer surface of the equipment housing.

[0015] To prevent water leakage between the mounting bracket and the counterbore and damage to the frequency converter, a waterproof convex ring surrounding the through hole is provided on the counterbore, and a waterproof ring groove matching the waterproof convex ring is provided on the mounting bracket. When the mounting bracket is installed on the counterbore, the waterproof convex ring is tightly clamped in the waterproof ring groove to prevent water from seeping in.

[0016] Further, to enhance the waterproof effect, a waterproof gasket is provided between the mounting bracket and the counterbore.

[0017] To facilitate the removal of the frequency converter during maintenance and replacement, accommodation grooves are provided at opposite edges of the surface of the mounting bracket facing away from the frequency converter, and a lifting ring is provided in the accommodation groove.

[0018] In this application, the lifting ring is in a U-shape, and its two ends are rotatably connected to the opposite side walls of the accommodation groove. When not in use, the lifting ring rotates and is accommodated in the accommodation groove. When in use, the lifting ring is flipped to stand up perpendicular to the surface of the mounting bracket to facilitate manual lifting and pulling out the mounting bracket and the frequency converter.

[0019] An integrated frequency conversion component provided by the present utility model avoids damage caused by collision by integrating the frequency converter inside the equipment housing.

[0020] In addition, through the cooperation of the mounting bracket, the counterbore, and the through hole, the frequency converter is detachably installed on the equipment housing, so that the frequency converter can be pre-wired outside the equipment housing and then inserted into the equipment housing for installation. When the frequency converter needs to be repaired or replaced, the frequency converter can also be directly disassembled and taken out, facilitating the connection and maintenance of the frequency converter.

[0029] As Figures 2 to 4 shown, an embodiment of the present utility model provides an integrated frequency conversion component, including an equipment housing 1, a frequency converter 2 and a mounting bracket 3;

[0030] A through hole 11 is provided on the equipment housing 1 for inserting the frequency converter 2 into the equipment housing 1. A counterbore 12 is provided around the through hole 11, and the mounting bracket 3 is installed on the counterbore 12;

[0031] The periphery of the mounting bracket 3 abuts against the counterbore 12. A plurality of first mounting holes 31 are provided on the mounting bracket 3, and the plurality of first mounting holes 31 are arranged at intervals along the edge of the mounting bracket 3. A plurality of second mounting holes 13 are provided on the counterbore 12 corresponding to the positions of the plurality of first mounting holes 31. The mounting bracket 3 is detachably installed on the counterbore 12 by bolts passing through the first mounting holes 31 and being in threaded cooperation with the second mounting holes 13;

[0032] One end of the frequency converter 2 is connected to the mounting bracket 3, and the other end passes through the through hole 11 and is inserted into the equipment housing 1.

[0033] In this embodiment, the frequency converter 2 is in the shape of a rectangular body, the mounting bracket 3 is a rectangular plate, and the contours of the counterbore 12 and the through hole 11 are both rectangular.

[0034] Among them, the outer contour of the mounting bracket 3 is matched with the outer contour of the counterbore 12, and the contour of the through hole 11 is matched with the corresponding contour of the frequency converter 2.

[0035] When the mounting frame 3 and the inverter 2 are inserted into the device housing 1, the through hole 11 positions the inverter 2 and supports the inverter 2. The mounting frame 3 is embedded in the corresponding sink groove of the sink platform 12 and is engaged with the sink groove, which not only positions the mounting frame 3 but also reinforces the fixing of the mounting frame 3.

[0036] The through hole 11 is located in the sinker 12, and preferably located at the center of the sinker 12. The width of the sinker 12 around the through hole 11 is preferably the same, and the width is preferably 2-4 cm, so as to provide a sufficient installation area and make the structural strength of the sinker 12 around the through hole 11 the same, providing the same support effect for the mounting frame 3.

[0037] The depth of the sink 12 is preferably the same as the thickness of the mounting frame 3, so that when the mounting frame 3 is installed on the sink 12, the outer surface of the mounting frame 3 is flush with the outer surface of the device housing 1, which can not only improve the appearance of the device, but also prevent the mounting frame 3 from protruding from the device housing 1, causing scratches on the human body or being easily damaged by collision.

[0038] As an electronic product, the inverter 2 is not only easily damaged by collision, but also the electronic components may be damaged by water. The inverter 2 is used in a wide range of equipment and in different environments. In order to avoid water leakage between the mounting frame 3 and the sink 12, which may damage the inverter 2, a waterproof convex ring 14 surrounding the through hole 11 is provided on the sink 12, and a waterproof ring groove 32 cooperating with the waterproof convex ring 14 is provided on the mounting frame 3. When the mounting frame 3 is installed on the sink 12, the waterproof convex ring 14 is tightly stuck in the waterproof ring groove 32 to prevent water from penetrating.

[0039] Furthermore, in order to enhance the waterproof effect, a waterproof gasket 4 is further provided between the mounting frame 3 and the sink 12. The waterproof gasket 4 can be provided on the periphery of the waterproof convex ring 14 and the waterproof annular groove 32, or can be provided between the waterproof convex ring 14 and the waterproof annular groove 32. In this embodiment, the waterproof gasket 4 is provided between the waterproof convex ring 14 and the waterproof annular groove 32, and the waterproof effect is improved by clamping the waterproof convex ring 14 and the waterproof annular groove 32.

[0040] like Figure 5 As shown, the mounting frame 3 is provided with a receiving groove 33 at the opposite edge of the plate surface on the side away from the inverter 2, and a lifting ring 34 is provided in the receiving groove 33. Since the mounting frame 3 is installed on the sink 12 in an embedded manner, when the inverter 2 needs to be repaired or replaced, there is no force point on the mounting frame 3 to apply force outwards, and it is not easy to take out the mounting frame 3 and the inverter 2. By providing the lifting ring 34, a force point for applying force outwards is provided for the mounting frame 3, so that the mounting frame 3 and the inverter 2 can be easily taken out.

[0041] In this embodiment, the lifting ring 34 is in a U-shape and can be integrally bent from a metal rod. Its two ends are rotatably connected to the opposite side walls of the receiving groove 33. When the lifting ring 34 is not in use, it lies flat as a whole and is received in the receiving groove 33. When in need of use, the lifting ring 34 is flipped to make it stand up and vertically installed on the plate surface of the mounting frame 3, so as to facilitate manual lifting and pull out the mounting frame 3 and the frequency converter 2.

[0042] Preferably, the lifting ring 34 is at one end of the side wall of the receiving groove 33, so that the size of the receiving groove 33 can be reduced. Preferably, the receiving groove 33 is located at the edge of the mounting frame 3 and is communicated with the side of the mounting frame 3. When the lifting ring 34 lies flat, it rotates towards this side of the mounting frame 3, so as to minimally occupy the middle part of the front surface of the mounting frame 3, reserve an exposed space for some frequency converters 2 with control buttons, and reduce the size of the mounting frame 3.

[0043] In addition, a clamping lug 35 protrudes into the receiving groove 33 from the outer edge of the side wall of the receiving groove 33, which is used to stably clamp the lifting ring 34 in the receiving groove 33, so that the lifting ring 34 is stably received. When the lifting ring 34 needs to be rotated, a force needs to be applied to overcome the clamping of the clamping lug 35.

[0044] An integrated frequency conversion component provided by the present utility model avoids damage caused by collision by integrating the frequency converter 2 into the device housing 1.

[0045] In addition, through the cooperation of the mounting frame 3, the counterbore 12 and the through hole 11, the frequency converter 2 is detachably mounted on the device housing 1, so that the frequency converter 2 can be pre-wired outside the device housing 1 and then inserted into the device housing 1 for installation. When the frequency converter 2 needs to be repaired or replaced, the frequency converter 2 can also be directly disassembled and taken out, which is convenient for the connection and repair of the frequency converter 2.
