Description

[0001] The present application relates to the technical field of inverters, in particular to a shell mechanism, and further relates to an inverter comprising the shell mechanism. BACKGROUND

[0002] Energy storage inverters are widely used in renewable energy power generation systems such as solar and wind energy, and are suitable for electric energy storage systems, micro-grid systems, electric vehicle charging piles and other fields. They provide key support for energy conversion between direct current energy and alternating current load, promote the application of clean energy and energy transformation, and can realize charging and discharging actions to provide support for bidirectional energy conversion. Generally, by controlling the on-off of the switching tube, direct current energy is converted into alternating current energy through an inverter circuit. When the energy storage system discharges, the inverter converts the stored direct current energy into alternating current energy output; when charging, the input alternating current energy is converted into direct current energy required by the energy storage system for charging.

This allows for the adjustment and replacement of side plates of different lengths and sizes according to product needs, thus enabling the construction of housings of different sizes. The simple structure also helps reduce the production cost of housings for various size requirements. Because the support plates form an angle, adjacent side plates can be connected by the support plates at a specific arc, providing a basis for building housings of different shapes. By simply changing the angle between two adjacent support plates of the arc-shaped component, it can be adapted to the corner connection of housings of different shapes. The arc-shaped components installed in close contact with the side plates ensure the firm assembly of the housing structure and simplify the manufacturing process. The smooth connection between the arc-shaped support and the sealing rib improves the sealing performance at the corners of the housing, meeting the user's needs.

[0034] 2. The first slot is located at the top and bottom edges of the side plate and is arranged along the height direction, which facilitates the installation of the locking component when it is installed vertically; while the second slot is provided on the top outer wall of the side plate and extends horizontally, which facilitates the provision of a lateral fixing point for the top plate when the locking component is installed horizontally, thereby providing an installation path for it; by providing the first slot and the second slot on one side plate at the same time, it is easy to adapt to the top plate with two different installation methods, and has strong adaptability.

Rather, the use of the words such as "exemplary" or "for example" is intended to present the relevant concept in a specific manner.

[0057] Figure 1 is a perspective structural schematic view of a shell mechanism according to an embodiment of the present application, and includes a bottom plate 1, a top plate 2, and a plurality of side plates 3 connected between the bottom plate 1 and the top plate 2 and sequentially connected through arc-shaped members 4, the arc-shaped members 4 at least include: support plate bodies 41 configured as two and respectively fitted to one end face of each of two adjacent side plates 3 close to each other, a first opening 42 is opened through the thickness direction of each support plate body 41 and configured as at least one, the two support plate bodies 41 are led out from the same end and form a certain arc angle with each other; the end of the side plate 3 fitted with the plate body is provided with a second opening 31 opposite to the first opening 42, and the fixation of the side plate 3 and the support plate body 41 is realized through the locking member 10 sequentially threaded in the first opening 42 and the second opening 31.

[0058] In this arrangement, with reference to Figures 1-6Since the arc-shaped member 4 is used to connect between the adjacent side plates 3, the detachable connection between the side plate 3 and the arc-shaped member 4 is facilitated through the first opening 42 on the support plate body 41, the second opening 31 on the side plate 3 and the locking unit, so that the side plate 3 of different length and size can be adjusted and replaced according to the product requirement, and then the cabinet of different size can be built, which is simple in structure and can reduce the production cost of the cabinet under the requirement of multiple sizes; in addition, since the support plate body 41 forms an included angle, the adjacent side plates 3 can be connected through the support plate body 41 with a specific radian, thereby providing a basis for building a cabinet of different shape, at this time, only by changing the angle between the adjacent two support plate bodies 41 of the arc-shaped member 4, the cabinet of different shape can be connected at the corner; the cooperation of the arc-shaped member 4, the first opening 42, the second opening 31 and the locking member 10 ensures the firm assembly of the cabinet structure, simplifies the manufacturing process, and can meet the use requirement of the user.

[0059] It should be noted that the support plate body 41 can be attached to the end face of the adjacent two side plates 3 close to each other, thereby ensuring the tightness of the connection between the two; avoiding the difficulty of effectively shielding the gap between the two in the traditional clamping type connection mode; therefore, the arc-shaped member 4 attached and installed in the present application further enhances the tight connection of the corner of the cabinet mechanism under the premise of realizing the detachable connection with the side plate 3, and provides a structural basis for the sealed installation of the device placed in the cabinet.

[0060] In one case of the present embodiment, when the size of the above-mentioned cabinet mechanism needs to be adjusted, the locking member 10 can be taken out from the first opening 42 and the second opening 31, since the side plate 3 and the arc-shaped member 4 are separated, the side plate 3 of different length or width can be replaced, thereby realizing the effective adjustment of the size of the cabinet mechanism, and building a cabinet that meets the size requirement; compared with the traditional fixed installation and integrated cabinet, the present embodiment only needs to replace the side plate 3 to realize the size adjustment, thereby reducing the production cost of the cabinet under the requirement of multiple sizes.

[0061] In another case of the present embodiment, when the shape of the above-mentioned cabinet mechanism needs to be changed, the arc-shaped member 4 with different angles between the two support plate bodies 41 is replaced, thereby facilitating the adaptation to the cabinet of different shape, in combination with the first opening 42 and the second opening 31 on the side plate 3, thereby realizing the shape adjustment of the cabinet mechanism, and facilitating the building of the cabinet of different shape according to the requirement; which is simple in structure and can meet the use requirement of the user.

[0062] Further specific implementation or refinement, improvement process of the board card plug-in box assembly will be introduced by exemplary illustration as follows, in order to further improve it or for other aspects of improvement consideration.

[0063] In practical application, as shown in Figure 3 and Figure 4 , the arc-shaped member 4 further comprises: two arc-shaped plate bodies 43 arranged between the two opposite ends of the two support plate bodies 41 in the height direction; the two arc-shaped plate bodies and the two support plate bodies 41 form an opening on the side away from the included angle; and a removable cover is arranged outside the opening and provided with a shielding cover 44 for shielding the opening.

[0064] It can be seen that, by arranging the arc-shaped plate body 43 between the corresponding ends of the two support plate bodies 41, on the one hand, the stability and rigidity of the entire arc-shaped member 4 can be enhanced, ensuring that it is effectively installed above the bottom plate 1, and on the other hand, the force acting on the shell can be effectively dispersed, further improving the stability and anti-deformation ability of the shell.

[0065] Specifically, the opening can reduce the internal mass while ensuring the overall stability of the arc-shaped member 4, and the shielding cover 44 can effectively shield the opening, further increasing the airtightness of the connection between the arc-shaped member 4 and the side plate 3. In addition, the removable arrangement facilitates the removal of the shielding cover 44 when needed, the internal operation, and the reinstallation, ensuring the airtightness of the shell.

[0066] It should be noted that, as shown in Figure 3 , the shielding cover 44 effectively prevents the influence of external environmental factors (such as dust, moisture, collision, etc.) on sensitive components inside the shell. In actual operation, the shielding cover 44 can be arranged as an arc-shaped plate with an arc length and a central angle greater than that of the opening of the arc-shaped member 4.

[0067] In one case of the embodiment, as shown in Figures 4-6 , it further comprises: a sealing rib 32 formed on each side plate 3 near the top plate 2, a supporting position 45 arranged on the arc-shaped plate body 43 near the top plate 2 of the arc-shaped member 4, and a first sealing member 5 arranged to press-fit the sealing rib 32 and the supporting position 45 to seal the gap between the side plate 3 and the top plate 2. The supporting position 45 is arranged as an arc-shaped cross-section with smooth connections at both ends to the sealing rib 32 on the adjacent two side plates 3.

[0068] It can be seen that, by arranging the sealing rib 32 on the side plate 3 near the top plate 2 and the supporting position 45 on the upper arc-shaped plate body 43, a foundation is provided for the installation of the first sealing member 5. The supporting position 45 is arranged in two sections and is smoothly connected to the sealing rib 32 on the side plate 3, so that the first sealing member 5, which was originally only installed on the side plate 3, can also be installed above the arc-shaped member 4, thereby ensuring effective sealing at the corner of the adjacent side plates 3 and improving the sealing effect at the corner connection of the shell.

[0069] It should be noted that the supporting position 45 located above the arc-shaped plate body 43 can not only serve as a structural support, but also assist in enhancing the sealing effect at the corner connecting the side plate 3, especially through its specific arc-shaped design, which can better adapt to and cooperate with the sealing rib position 32 on the side plate 3, thereby achieving a more tightly sealed closure.

[0070] In another case of the present embodiment, referring to Figure 1 and Figure 6 , further comprising: a sealing groove 6 opened at one of the arc-shaped plate bodies 43 near one end of the bottom plate 1 and at the bottom of each side plate 3; and a second sealing member 7 configured to be crimped inside the sealing groove 6 to seal the side plate 3 and the bottom plate 1,

[0071] As can be seen, through the sealing groove 6 provided on the bottom arc-shaped plate body 43, the second sealing member 7 can be received and placed, thereby sealing the gap between the side plate 3 and the bottom plate 1, ensuring that the two are tightly fitted without gaps.

[0072] For example, the first sealing member 5 and the second sealing member 7 can be sealing strips, which are embedded in the sealing groove 6 or crimped above the sealing rib position 32 and the supporting position 45, thereby sealing the gap between the side plate 3 and the bottom plate 1 or the top plate 2 through their own elasticity and compression deformation.

[0073] Of course, the first sealing member 5 and the second sealing member 7 can also be gaskets or polyurethane foam sealing strips, which can effectively fill the gap and enhance the sound insulation and heat preservation effect by utilizing their own elastic force and compression performance; as for the specific types, the present embodiment does not make specific limitations here.

[0074] In actual operation, referring to Figure 6 , one of the first opening 42 and the second opening 31 is configured as a through hole, and the other is configured with a plurality of tooth-shaped portions formed on the inner wall, and the locking member 10 is configured as a screw that is sequentially threaded and engaged with the tooth-shaped portions.

[0075] It can be seen that by setting the first opening 42 and the second opening 31 as through holes or with tooth-shaped portions, the locking member 10 can be detachably connected between the first opening 42 and the second opening 31, improving the detachability of the entire shell; by rotating the locking member 10, it can interact with the tooth-shaped portions to achieve the effect of locking or loosening.

[0076] It should be noted that the opening with multiple teeth on the inner wall can adopt a threaded structure, which allows a specific type of locking member 10 (such as a screw) to engage with it, thereby achieving more precise positioning or locking effect when rotated; the form of the tooth-shaped portion can be straight threads, sawtooth or other customized geometric shapes to meet the needs of detachable connection.

[0077] Exemplarily, the first hole 42 and the second hole 31 can be both threaded holes, or one of them can be a threaded hole and the other one can be a light hole; or both of them can be light holes, in which case the locking member 10 is arranged as a pin with a small interference fit in the two light holes, so as to stably connect the arc-shaped member and the side plate 3 in daily use, and to separate them by external force when needed.

[0078] In one case of the embodiment, referring to Figures 6-9 , it further comprises a first slot 33 respectively arranged at the top end and the bottom end of the side plate 3 and extending along the height direction, and the top plate 2 and the first slot 33 and the bottom plate 1 and the first slot 33 are both fixed by the locking member 10.

[0079] It can be seen that the first slot 33 is arranged at the top and bottom edges of the side plate 3 and extends along the height direction, which can provide a path for the installation of the locking member 10, so as to connect and fix the top plate 2 and the bottom plate 1, thereby providing a mounting basis for the locking member 10 when it is installed along the vertical direction.

[0080] In which case, Figure 7 is a sectional view of the top plate 2 of the shell mechanism when it is vertically positioned, and specifically referring to Figure 6 , Figure 8 and Figure 9 , the first slot 33 extending along the vertical direction is used to fix and position the top plate 2 and the bottom plate 1 by the locking member 10, so as to adapt to the vertically positioned top plate 2.

[0081] On this basis, referring to Figure 6 , it further comprises a second slot 34 arranged at the top outer wall of the side plate 3 and extending along the horizontal direction, and the second slot 34 is configured to cooperate with the horizontally installed locking member 10 to position the top plate 2.

[0082] In which case, Figure 9 is a perspective view of the top plate 2 of the shell mechanism when it is horizontally positioned, and specifically referring to Figure 6 , Figures 10-13 , the second slot 34 extending along the horizontal direction is used to fix and position the top plate 2 by the locking member 10, so as to adapt to the horizontally positioned top plate 2.

[0083] It can be seen that by arranging the second notch 34 extending horizontally on the outer wall of the top of the side plate 3, an additional transverse fixing point is provided for the top plate 2 when the locking member 10 is installed along the horizontal direction, thereby providing an installation path for the top plate 2; by arranging the first notch 33 and the second notch 34 on one side plate 3, the top plate 2 can be adapted to two different installation modes, thereby having strong adaptability.

[0084] In another case of the embodiment, referring to Figure 6 , the tooth portion is arranged on the inner wall of the first notch 33 and the second notch 34 and is configured to be engaged with the locking member 10 and is in a plurality, and the first notch 33 and the second notch 34 each extend along the length direction of the side plate 3 from one end to the other end.

[0085] It can be seen that by arranging the tooth portion on the inner wall of the first notch 33 and the second notch 34, the tooth portion is engaged with the locking member 10 to achieve detachable connection therebetween; the tooth portion is engaged with the locking member 10 to increase the stability and anti-falling ability of the connection.

[0086] For example, the number of tooth portions can be a plurality to ensure that the locking member 10 is effectively engaged and supported throughout the length of the notch; the first notch 33 and the second notch 34 extend along the length direction of the side plate 3 from one end to the other end, so that the notches cover the full length of the side plate 3 and also ensure effective connection of the top plate 2 and the side plate 3 and the bottom plate 1 and the side plate 3 at various positions, thereby further enhancing the stability and durability of the shell.

[0087] For example, the above-mentioned locking member 10 can be a screw, a pin, or other suitable fastener, which is connected by penetrating the first notch 33, the second notch 34, and the corresponding structure (such as a threaded hole, a fixing seat, etc.) on the other side of the top plate 2 or the bottom plate 1, thereby completing the connection of the top plate 2 and the side plate 3 and the connection between the bottom plate 1 and the side plate 3, and the specific type and installation mode are not limited by the embodiment.

[0088] Further, referring to Figure 4 , each support plate body 41 is provided with two first openings 42 opposite in the height direction, and a second opening 31 is formed at the end of each first notch 33 and is arranged in communication with the first notch 33.

[0089] It can be seen that the two first openings 42 distributed in the height direction facilitate stable connection of the support plate body 41 and the side plate 3, thereby enhancing the overall stability of the shell and making the assembly and fixing process more reliable and efficient.

[0090] In one case of the embodiment, as shown in Figures 1-4 , the above-mentioned side plate 3 is configured as four and is distributed at the four corners of the bottom plate 1, and the included angle is configured as 90 degrees.

[0091] It can be known that the four side plates 3 are respectively located at four corners of the bottom plate 1, forming a main part of the shell, and by setting the included angle of the support plate body 41 to 90 degrees, it is convenient to adapt to the four side plates 3, and the overall stability is ensured.

[0092] Exemplarily, the side plate 3 can also be set to three, five, six or even more, corresponding to a three-prism, five-prism, six-prism shell, etc.; at this time, only the included angle between the two support plate bodies 41 needs to be adjusted, and the specific shape and angle are not limited by the embodiment.

[0093] In another case of the embodiment, it also includes a heat sink 8 arranged between the two support plate bodies 41 of each arc-shaped member 4, and / or a plurality of heat dissipation teeth 9 arranged on the outer side wall of each side plate 3 and spaced apart along the height direction thereof, and the heat sink 8 is configured to be sequentially and spaced apart along the length direction of the support plate body 41.

[0094] It can be known that the heat sink 8 is arranged between the two support plate bodies 41 of each arc-shaped member 4, which is convenient to increase the heat exchange area and improve the heat dissipation efficiency at the corner, in addition, the design of the heat sink 8 helps to dissipate the heat generated in the shell, preventing overheating from affecting the performance or service life of the equipment.

[0095] The embodiment also provides an inverter, as shown in the figure, which includes the shell mechanism as described above and an inverter unit arranged in the shell mechanism, and the bottom plate 1 is arranged as a heat sink.

[0096] It is not difficult to see that by using the shell mechanism for the inverter structure, the detachable connection between the side plate 3 and the arc-shaped member 4 is realized, and different lengths and sizes of the side plate 3 can be adjusted and replaced according to product needs, and then a shell of different size is built; the bottom plate 1 is arranged as a heat sink to facilitate ensuring the heat dissipation performance of the inverter; because the included angle is formed between the support plate bodies 41, the adjacent side plates 3 can be connected through the support plate bodies 41 at a specific radian, thereby providing a basis for building a shell of different shapes, only the angle between the two adjacent support plate bodies 41 of the arc-shaped member 4 needs to be changed, which can be adapted to the connection at the corner of the shell of different shapes; under the premise of ensuring the firm assembly of the inverter shell structure, the simple structure also facilitates reducing the production cost of the inverter under the demand of multiple sizes, and the use demand of the user can be met.

[0097] The above examples mainly illustrate the shell mechanism of the present application and the inverter comprising the shell mechanism. Although only some of the embodiments of the present application are described, it should be understood by those skilled in the art that the present application can be implemented in many other forms without departing from the spirit and scope of the present application. Therefore, the examples and embodiments shown are considered to be illustrative rather than restrictive, and the present application can encompass various modifications and alternatives without departing from the spirit and scope of the technical solutions of the present application.
