Description

Technical Field

[0001] The utility model relates to the technical field of new energy power electronics, and particularly relates to an inverter housing integrated with a handle function. Background Art

[0002] An inverter is a converter that converts direct current electrical energy (battery, storage battery) into fixed-frequency and fixed-voltage or frequency-modulated and voltage-regulated alternating current (generally 220V, 50Hz sine wave). It consists of an inverter bridge, control logic, and a filter circuit.

[0003] Existing inverter housings integrated with a handle function on the market, such as Figures 1 to 3 As shown, the inverter housing includes a hollow base 1a. The base 1a is generally rectangular in shape, including a base portion and an outer edge portion arranged in a continuous ring shape. The top end of the base portion is open, the side walls are continuously arranged, the outer edge portion includes a connecting portion and an upward extending portion. The connecting portion protrudes laterally outward from the side wall of the base portion. The inner end of the connecting portion is connected to the top end of the base portion, and the outer end is connected to the bottom end of the upward extending portion. The side wall includes a connected straight side wall section and a side wall transition rounded corner section. The upward extending portion includes a connected straight upward extending section and an upward extending rounded corner transition section. The radius of the circle where the upward extending rounded corner transition section is located is equal to the radius of the circle where the side wall transition rounded corner section is located. Additionally, usually, the flange surface size on the base 1a (i.e., the width of the connecting portion) is increased. The increase in the width of the connecting portion is for two reasons. One is to reserve a position for the press riveting stud 3a for subsequent installation of the cover plate 2a. The other is to reserve a handling grip point on the flange surface for convenient handling.

[0004] However, the above-mentioned inverter housing integrated with a handle function has the following deficiencies:

[0005] Since the radius of the circle where the upward extending rounded corner transition section is located is equal to the radius of the circle where the side wall transition rounded corner section is located, and there is also a position reserved for the press riveting stud 3a on the flange surface, it causes the overall external dimensions of the aforementioned inverter housing integrated with a handle function to increase without increasing the internal volume of the base portion, thereby increasing the packaging cost and transportation cost.

[0006] In view of the above deficiencies, it is necessary to design a new inverter housing integrated with a handle function. Summary of the Utility Model

[0007] Therefore, the technical problem to be solved by the utility model is that for the existing inverter housing integrated with a handle function, since the radius of the circle where the upward extending rounded corner transition section is located is equal to the radius of the circle where the side wall transition rounded corner section is located, and there is also a position reserved for the press riveting stud on the flange surface, it causes the overall external dimensions to increase without increasing the internal volume of the base portion. Thus, an inverter housing integrated with a handle function is provided.

[0008] To solve the above technical problem, the technical solution of the utility model is as follows:

[0009] An inverter housing integrated with a handle function includes a hollow base. The base is generally rectangular in shape, including a base portion and an outer edge portion that is continuously annularly arranged. The top end of the base portion is open, and the side walls are continuously arranged. The outer edge portion includes a connecting portion and an upward extending portion. The connecting portion laterally protrudes outward from the side wall of the base portion. The inner end of the connecting portion is connected to the top end of the base portion, and the outer end is connected to the bottom end of the upward extending portion. The side wall includes a connected straight side wall section and a rounded transition side wall section. The upward extending portion includes a connected straight upward extending section and a rounded transition upward extending section. The radius R2 of the circle where the rounded transition upward extending section is located is smaller than the radius R1 of the circle where the rounded transition side wall section is located.

[0010] Further, R1 is from 70 mm to 90 mm, and R2 is from 34.5 mm to 38.5 mm.

[0011] Further, the distance L between the projections of the straight side wall section and the straight upward extending section in the horizontal plane is from 11 mm to 15 mm.

[0012] Further, R1 is 80 mm, R2 is 36.5 mm, and L is 13 mm.

[0013] Further, a handling force application area is provided on the connecting portion. The handling force application area is the area between the rounded transition side wall section and the corresponding rounded transition upward extending section.

[0014] Further, the inverter housing integrated with a handle function further includes a plurality of cover fixing members that are located inside the base portion and are spaced apart. The cover fixing members are fixed to the side wall of the base portion.

[0015] Further, the cover fixing member includes a fixing plate fixedly connected to the side wall, and a column body connected to the fixing plate and vertically arranged. A threaded hole is provided in the column body.

[0016] Further, the column body is fixedly connected to the fixing plate through an inclined rib plate.

[0017] Further, the column body protrudes above the top surface of the connecting portion.

[0018] Further, the inverter housing integrated with a handle function further includes a cover that is adapted to the upward extending portion. The cover is placed on the connecting portion, and the column body of the cover fixing member enters a through hole on the cover.

[0019] The technical solution of the present utility model has the following advantages:

[0020] 1. The inverter housing integrated with a handle function provided by the present utility model includes a hollow base. The base is in the shape of a cuboid as a whole, including a base portion and an outer edge portion arranged continuously in a ring shape. The top end of the base portion is open, and the side walls are continuously arranged. The outer edge portion includes a connecting portion and an upward extending portion. The connecting portion protrudes laterally outward from the side wall of the base portion. The inner end of the connecting portion is connected to the top end of the base portion, and the outer end is connected to the bottom end of the upward extending portion. The side wall includes a connected straight side wall section and a rounded transition side wall section. The upward extending portion includes a connected straight upward extending section and a rounded transition upward extending section. The radius R2 of the circle where the rounded transition upward extending section is located is smaller than the radius R1 of the circle where the rounded transition side wall section is located. Compared with the inverter housing integrated with a handle function in the prior art, since R2 is smaller than R1, with the position of the upward extending portion unchanged, the connecting portion becomes narrower, and the side walls of the entire base portion move outward. Therefore, the internal volume of the base portion can be increased. Also, since R2 is smaller than R1, with the internal volume of the base portion unchanged, it is equivalent to the upward extending portion moving inward and the connecting portion becoming narrower. Therefore, the overall external dimensions of the inverter housing integrated with a handle function can be reduced, and thus the packaging and transportation costs can be reduced.

[0021] 2. For the inverter housing integrated with a handle function provided by the present utility model, R1 ranges from 70 mm to 90 mm, R2 ranges from 34.5 mm to 38.5 mm, and the distance L between the projections of the straight side wall section and the straight upward extending section in the horizontal plane is from 11 mm to 15 mm. Such a numerical range selection can not only take into account that the handling force area on the inverter housing integrated with a handle function has a relatively large area, but also make the overall external dimensions of the inverter housing integrated with a handle function smaller.

[0022] 3. For the inverter housing integrated with a handle function provided by the present utility model, since the cover fixing member is located inside the base portion and is fixed to the side wall of the base portion, in this way, there is no need to reserve a position for the riveting bolt on the connecting portion. Therefore, the horizontal width of the connecting portion can be further reduced, and thus the overall external dimensions of the inverter housing integrated with a handle function can be further reduced.

Detailed implementation manners

[0037] Next, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0039] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "coupled" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0040] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0041] As Figures 4 to 10 shown, the present utility model provides an inverter housing integrated with a handle function, including a hollow base 1. The base 1 is generally rectangular in shape and includes a base portion 11 and an outer edge portion 12 arranged in a continuous ring (as Figure 4 shown). The top end of the base portion 11 is open, and the side walls are continuously arranged. The outer edge portion 12 includes a connecting portion 121 and an upward extending portion 122. The connecting portion 121 protrudes laterally outward from the side wall of the base portion 11. The inner end of the connecting portion 121 is connected to the top end of the base portion 11, and the outer end is connected to the bottom end of the upward extending portion 122. The side wall includes a connected side wall straight section 111 and a side wall transition rounded section 112 (as Figure 5 shown). The upward extending portion 122 includes a connected upward extending portion straight section 1221 and an upward extending portion rounded transition section 1222 (as Figure 5 shown). The radius R2 of the circle where the upward extending portion rounded transition section 1222 is located is smaller than the radius R1 of the circle where the side wall transition rounded section 112 is located.

[0042] The inverter housing integrated with a handle function provided by the present utility model, compared with the inverter housing integrated with a handle function in the prior art, since R1 is greater than R2, with the position of the upper extension part 122 remaining unchanged, the connecting part 121 becomes narrower, and the side wall of the entire base part 11 moves outward. Therefore, the internal volume of the base part 11 can be increased. Also, since R2 is less than R1, with the internal volume of the base part 11 remaining unchanged, it is equivalent to the upper extension part 122 moving inward and the connecting part 121 becoming narrower. Therefore, the overall external dimensions of the inverter housing integrated with a handle function can be reduced, and thus the packaging and transportation costs can be lowered.

[0043] Further, the radius R1 of the circle where the side wall transition rounded corner section 112 is located is 70 mm to 90 mm, the radius R2 of the circle where the upper extension part rounded corner transition section 1222 is located is 34.5 mm to 38.5 mm. The distance L (as shown in Figure 4 , Figures 6 to 8 ) between the projection in the horizontal plane of the side wall straight section 111 (as shown in Figure 5 to the body 8) and the projection in the horizontal plane of the upper extension part straight section 1221 (as shown in Figure 9 ) of the upper extension part 122 is 11 mm to 15 mm. Such a numerical range selection can not only take into account that the handling force application area 1211 of the inverter housing integrated with a handle function has a relatively large area, but also make the overall external dimensions of the inverter housing integrated with a handle function smaller.

[0044] Further, a handling force application area 1211 is provided on the connecting part 121. The handling force application area 1211 is the area between the side wall transition rounded corner section 112 and the corresponding side wall transition rounded corner section 1222. During the handling process, the handling force application area 1211 provides a force application position for the worker, facilitating the worker to handle.

[0045] Preferably, the radius R1 of the circle where the side wall transition rounded corner section 112 is located is 80 mm, the radius R2 of the circle where the upper extension part rounded corner transition section 1222 is located is 36.5 mm, and the distance L between the projection in the horizontal plane of the side wall straight section 111 on the base part 11 and the projection in the horizontal plane of the upper extension part straight section 1221 on the upper extension part 122 is 13 mm.

[0046] Further, it further includes a cover plate 2 adapted to the upper extension part 122. The inverter housing integrated with a handle function further includes a plurality of cover plate fixing members 13 that are located inside the base part 11 and are spaced apart. The cover plate fixing members 13 are used to fix the cover plate 2, and the cover plate fixing members 13 are fixed on the side wall of the base part 11. Since the cover plate fixing members 13 are located inside the base part 11 and the cover plate 2 fixing members are fixed on the side wall of the base part 11, in this way, there is no need to reserve a setting position for riveting bolts on the connecting part 121. Therefore, the horizontal width of the connecting part 121 can be further reduced, and thus the dimensions of the inverter housing integrated with a handle function can be further reduced.

[0047] In this embodiment, the cover fixing member 13 is integrally formed and includes a fixing plate 131 fixedly connected to the side wall, and a column 133 connected to the fixing plate 131 and vertically arranged. A threaded hole 1331 is formed in the column 133. The column 133 is fixedly connected to the fixing plate 131 through an inclined rib plate 132. The column 133 protrudes from the top surface of the connecting portion 121 so that when it enters the upper extension portion 122 and is placed on the connecting portion 121, the column 133 can enter the through hole 21 on the cover plate 2.

[0048] Before handling, first assemble the inverter housing integrated with the handle function. Specifically, align the edge of the cover plate 2 with the inner wall of the upper extension portion 122, place the cover plate 2 on the connecting portion 121, insert the column 133 of the cover fixing member 13 into the through hole 21 on the cover plate 2, and insert a screw (not shown) into the threaded hole 1331 of the column 133 from top to bottom to fix the cover plate 2 on the base 1.

[0049] As Figure 10 shown, when handling, two workers stand on two opposite sides of the inverter housing integrated with the handle function respectively, apply force to the handling force area 1211, lift the inverter housing integrated with the handle function and move it to a preset position.

[0050] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
