[0033] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0034] Example 1
[0035] refer to Figure 1 and Figure 2 As shown, an embodiment of the present application provides an inverter 100 , which includes a housing 110 , a cover 120 , and an inductor assembly 130 .
[0036] Specifically, combined Figure 2 and Figure 4As shown, the shell 110 is provided with an opening 111, and a reinforcing component 112 is provided on a side of the shell 110 away from the opening 111, and the reinforcing component 112 includes a first reinforcing member 1121 and a second reinforcing member 1122, and the first reinforcing member 1121 is a honeycomb structure; the cover 120 is sealed on the opening 111, and the cover 120 is connected to the shell 110 and defines a receiving cavity 140, and the first reinforcing member 1121 abuts against the second reinforcing member 1122 and the receiving cavity 140 40; the inductor component 130 is arranged on the reinforcement component 112 in the accommodating cavity 140, the cover body 120 is connected to the shell body 110, and the reinforcement component 112 of the accommodating cavity 140 defined by the two is used to place the inductor component 130, and the reinforcement component 112 is arranged to reinforce the shell body 110, and the first reinforcement member 1121 and the second reinforcement member 1122 of the honeycomb structure work together to reinforce the shell body 110 to reduce the damage of the inductor component 130 during bumps and collisions.
[0037] It should be noted that the inductor assembly 130 includes an inductor, which can be called a reactor. Generally, it is composed of a skeleton, a winding, a magnetic core, a shielding cover, a packaging material, etc. It is a component that can convert electrical energy into magnetic energy and store it. The inductor is one of the key components in the inverter 100. Of course, the inverter 100 also includes other types of components, which will not be described in detail here.
[0038] It is understandable that if Figure 2 and Figure 3 As shown, the honeycomb structure is a geometric structure that imitates the natural bee hive. This structure is composed of multiple hexagonal units. The hexagon can most efficiently fill a plane without gaps while maintaining the stability and lightness of the structure.
[0039] Optionally, refer to Figure 2 As shown, the first reinforcement member 1121 abuts against the side wall of the accommodating cavity 140, and the impact energy received by the first reinforcement member 1121 can be transmitted through the side wall of the accommodating cavity 140, thereby enhancing the impact resistance of the first reinforcement member 1121 and improving the stability of the first reinforcement member 1121. Furthermore, the first reinforcement member 1121 is provided with a plurality of reinforcement plates arranged in parallel and spaced apart to reduce the overall weight of the first reinforcement member 1121, and the reinforcement plates abut against the side wall of the accommodating cavity 140.
[0040] In one embodiment, optionally, Figure 3As shown, a third reinforcement 121 is provided on one side of the cover body 120 close to the shell 110. The third reinforcement 121 is a honeycomb structure. The third reinforcement 121 of the honeycomb structure improves the impact resistance of the cover body 120 and can reduce the weight of the cover body 120, thereby improving the firmness of the cover body 120.

One of the positioning pieces 113 is plugged into one of the positioning holes 122. The connection structure between the positioning piece 113 and the positioning hole 122 has a positioning and limiting effect. The positioning piece 113 of the shell 110 is plugged into the positioning hole 122 of the cover body 120, so that the cover body 120 can cover the opening 111 of the shell 110.
[0042] In one embodiment, optionally, reference Figure 4 and Figure 5 As shown, a first limiting boss 124 is provided on one side of the cover body 120 close to the shell 110, and a second limiting boss 116 is provided at the opening 111 of the shell 110. The first limiting boss 124 abuts against the second limiting boss 116 so that the cover body 120 and the shell 110 form a sealing structure to prevent water from entering the gap at the connection position and improve the sealing and waterproof performance.
[0043] In summary, the inverter 100 can be applied to an energy storage system. The cover body 120 of the inverter 100 is connected to the shell 110. The reinforcement component 112 of the accommodating cavity 140 defined by the two is used to place the inductor component 130. The reinforcement component 112 is provided to reinforce the shell 110. The first reinforcement member 1121 and the second reinforcement member 1122 of the honeycomb structure work together to reinforce the shell 110, thereby reducing damage to the inductor component 130 during bumps and collisions, thereby improving the overall impact resistance of the inverter 100.
[0044] Example 2
[0045] refer to Figures 1 to 3 As shown, an embodiment of the present application provides another inverter 100 , which includes a housing 110 , a cover 120 , and an inductor assembly 130 .
[0046] Specifically, combined Figure 2 and Figure 4As shown, the housing 110 has an opening 111, and a reinforcement component 112 is disposed on a side of the housing 110 away from the opening 111. The reinforcement component 112 includes a first reinforcement member 1121 and a second reinforcement member 1122. The first reinforcement member 1121 is a honeycomb structure. The cover 120 covers the opening 111. The cover 120 is connected to the housing 110 and defines a receiving cavity 140. The first reinforcement member 1121 abuts between the second reinforcement member 1122 and the bottom of the receiving cavity 140. The inductor component 130 is disposed in the receiving cavity 140. On the reinforcement component 112, the cover 120 is connected to the housing 110, and the reinforcement component 112 of the accommodating cavity 140 defined by the two is used to place the inductor component 130. The reinforcement component 112 is provided to reinforce the housing 110, and the second reinforcement member 1122 can reinforce and fix the first reinforcement member 1121 of the honeycomb structure. The first reinforcement member 1121 and the second reinforcement member 1122 of the honeycomb structure work together to reinforce the housing 110, thereby reducing the damage of the inductor component 130 during bumps and collisions. Exemplarily, the second reinforcement member 1122 is a reinforcement plate.
[0047] refer to Figure 3 As shown, the inverter 100 has a first direction. Exemplarily, the first direction is taken as the length direction of the inverter 100. It is understood that the above definition is only for the convenience of understanding the relative position relationship of each part in the inverter 100, and should not be understood as a limitation to the present application.
[0048] Optionally, refer to Figure 2 As shown, the first reinforcement member 1121 abuts against the side wall of the accommodating cavity 140, and the impact energy received by the first reinforcement member 1121 can be transmitted through the side wall of the accommodating cavity 140, thereby enhancing the impact resistance of the first reinforcement member 1121 and improving the stability of the first reinforcement member 1121. Further, the first reinforcement member 1121 is provided with a plurality of reinforcement plates arranged in parallel and spaced apart to reduce the overall weight of the first reinforcement member 1121, and the reinforcement plates abut against the side wall of the accommodating cavity 140. Exemplarily, the plurality of reinforcement plates are arranged in parallel and spaced apart along the first direction.
[0049] Alternatively, if Figure 3 As shown, a third reinforcement 121 is provided on one side of the cover body 120 close to the shell 110. The third reinforcement 121 is a honeycomb structure. The third reinforcement 121 of the honeycomb structure improves the impact resistance of the cover body 120 and can reduce the weight of the cover body 120, thereby improving the firmness of the cover body 120.
[0050] In one embodiment, optionally, reference Figure 4 and Figure 5As shown, a first limiting boss 124 is provided on one side of the cover body 120 close to the shell 110, and a second limiting boss 116 is provided at the opening 111 of the shell 110. The first limiting boss 124 abuts against the second limiting boss 116 to form a sealing structure between the cover body 120 and the shell 110 to prevent water from entering the gap at the connection position and improve the sealing and waterproof performance.
[0051] In the related art, it is inconvenient to open the housing 110 and the cover 120 for maintenance, and the connection between the housing 110 and the cover 120 is not firm enough, which affects the normal use and operation of the inverter 100.
[0052] In one embodiment, optionally, in combination Figure 2 and Figure 3 As shown, the cover 120 is provided with a plurality of first buckles 123 on one side close to the shell 110, and the opening 111 of the shell 110 is provided with a plurality of second buckles 115, and one of the first buckles 123 is engaged with one of the second buckles 115, so that the cover 120 is connected to the shell 110, and the connection between the two is relatively tight during use, reducing the situation of a gap between the cover 120 and the shell 110, and at the same time, the cover 120 and the shell 110 can be disassembled, so as to facilitate the installation and maintenance of the inductor assembly 130. Further, the first buckle 123 and the second buckle 115 can be made of elastic material, so that when the cover 120 and the shell 110 need to be separated to check and maintain the internal inductor assembly 130, the first buckle 123 and the second buckle 115 are in a movable engagement mode, and the first buckle 123 and the second buckle 115 can be engaged or separated.
[0053] In one embodiment, optionally, the cover body 120 is magnetically connected to the shell 110, and the attraction between the magnets can be used to connect the cover body 120 and the shell 110. Accordingly, the magnetic connection method enables the corresponding positions of the shell 110 and the cover body 120 to have an automatic alignment effect, so as to achieve a quick alignment connection between the shell 110 and the cover body 120.
[0054] In one embodiment, optionally, the cover body 120 and the shell 110 are interference fit, so that the cover body 120 has a certain interference when connected to the shell 110, and has a certain elastic deformation. For example, the assembly size of the cover body 120 is smaller than the assembly size of the shell 110, and has the characteristics of simple structure and high bearing capacity.
[0055] Exemplarily, gripping portions are extended from opposite ends of the housing 110 along the first direction to facilitate moving and carrying the inverter 100 through the gripping portions of the housing 110 .
[0056] In one embodiment, optionally, in combination Figure 2 and Figure 3 As shown, the housing 110 is provided with a positioning member 113, and the cover 120 is provided with a positioning hole 122 on one side close to the housing 110. One positioning member 113 is plugged into one positioning hole 122. The connection structure between the positioning member 113 and the positioning hole 122 has a positioning and limiting effect. By plugging the positioning member 113 of the housing 110 into the positioning hole 122 of the cover 120, the cover 120 can cover the opening 111 of the housing 110. Further, as Figure 3 As shown, the number of the positioning holes 122 is four, and the four positioning holes 122 are respectively arranged around the cover 120. Correspondingly, the number of the positioning members 113 is four, and the four positioning members 113 are located around the shell 110. Exemplarily, the four positioning holes 122 are located at the four corners of the cover 120, and the four positioning members 113 are located at the four corners of the shell 110.
[0057] In one embodiment, optionally, reference Figure 6 As shown, the inverter 100 also includes a connector 150. A through slot 114 is provided on the side of the shell 110 facing away from the cover body 120. The connector 150 is provided in the through slot 114. The connector 150 is used to install and seal the through slot 114. The connector 150 is connected to the inductor assembly 130, so that the inverter 100 can be connected to the energy storage battery pack through the connector 150.
[0058] Optionally, a button 160 is provided on the side of the inverter 100 , and the inverter 100 is turned on and off by the button 160 .

[0061] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.
