[0018] In order to make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] In this application, an inductor seal is provided on the side of the mounting opening of the mounting plate away from the inductor, and the inductor seal surrounds the periphery of the mounting opening. When the mounting portion passes through the mounting opening for installation, the surface in contact with the inductor seal is squeezed to form a tight contact, achieving a sealed fit. That is, the inductor seal is used to isolate the inside and outside at the interface position of the inductor installation, improving the sealing accuracy, thereby improving the dust and waterproof performance of the energy storage converter, more effectively protecting the power inner cabin of the energy storage converter from flying dust and rainwater entering, thus enhancing the safety protection level of the energy storage converter and reducing the occurrence of electrical faults; in addition, compared with applying glue, by directly setting the inductor seal at the mounting opening for sealing, the speed is faster and the production efficiency can be improved more.

[0020] Example 1

[0021] Combined with Figures 1 - 2 As shown, an inductor mounting structure of an energy storage converter provided by an embodiment of the present utility model includes an inductor 1 and a mounting plate 2. The inductor 1 includes at least one mounting portion 101, and the mounting plate 2 includes a mounting opening 201 for mating and installing with the mounting portion 101. An inductor seal 3 is provided on the side of the mounting plate 2 away from the inductor 1 and circumferentially located at the mounting opening 201. When the mounting portion 101 is assembled with the mounting opening 201, a sealed fit is formed with the inductor seal 3.

[0022] Among them, the energy storage converter can be an energy storage converter with a power of 1.725 WM. When installing the inductor 1 in the energy storage converter, it needs to be realized through the mounting plate 2. The mounting plate 2 separates the inner cabin and the outer cabin of the energy storage converter, and the inductor 1 is located in the outer cabin.

[0023] Specifically, on the inductor 1, at least one mounting portion 101 for assembling with the mounting plate 2 can be provided. Similarly, on the mounting plate 2, the mounting opening 201 is also provided corresponding to the structure, position, quantity, etc. of the mounting portion 101 to achieve the mating installation with the mounting portion 101, thereby fixedly connecting the inductor 1 to the mounting plate 2. In this embodiment, it can include 3 identical mounting portions 101, corresponding to 3 identical mounting openings 201. The 3 mounting portions 101 and the 3 mounting openings 201 can be assembled by means of plugging. Of course, it can also be other quantities of mounting portions 101 and mounting openings 201, which are not uniquely limited here.

[0024] More specifically, an inductor seal 3 is provided on the side of the mounting plate 2 facing away from the inductor 1, that is, an inductor seal 3 is provided on the side of the mounting plate 2 far from the inductor 1. Among them, the inductor seal 3 is used to seal the interface after the mounting port 201 and the mounting part 101 are assembled, realizing the isolation between the inner and outer cabins. An inductor seal 3 is provided at each mounting port 201, and the shape of the inductor seal 3 can be set based on the shape of the mounting port 201 to form a fit, which is conducive to more precise sealing around the mounting port 201. After the mounting part 101 passes through the mounting port 201, the contact surface between the inductor seal 3 and the mounting part 101 forms a tight contact to achieve a sealing fit, thereby reducing the entry of flying dust and rainwater into the inner cabin, and thus improving the protection level.

[0025] In the embodiment of the present invention, providing a mounting port 201 corresponding to the mounting part 101 of the inductor 1 on the mounting plate 2 can achieve the stable mounting of the inductor 1; an inductor seal 3 is provided on the side of the mounting port 201 of the mounting plate 2 facing away from the inductor 1, and the inductor seal 3 surrounds the periphery of the mounting port 201. When the mounting part 101 passes through the mounting port 201 for installation, the surface in contact with the inductor seal 3 is extruded to form a tight contact, achieving a sealing fit, that is, through the inductor seal 3 to isolate the inside and outside at the interface position where the inductor 1 is installed, improving the sealing accuracy, and thus improving the dust and waterproof performance of the energy storage converter, more effectively preventing flying dust and rainwater from entering the power inner cabin of the energy storage converter, thereby enhancing the safety protection level of the energy storage converter and reducing the occurrence of electrical faults; in addition, compared with applying glue to the mounting port 201 in sequence, by directly providing an inductor seal 3 at the mounting port 201 for sealing, the speed is faster and the production efficiency can be improved more.

[0026] Example 2

[0027] Combined Figures 1 - 2 As shown, in this embodiment, an insulating part 4 is further provided on the side of the mounting plate 2 facing away from the inductor 1. The insulating part 4 surrounds the mounting port 201, and the inductor seal 3 is attached to the insulating part 4 in the circumferential direction of the mounting port 201.

[0028] Specifically, an insulating part 4 is provided on the same side as the inductor seal 3, and the insulating part 4 surrounds all the mounting ports 201, that is, all the mounting ports 201 are opened at positions within the insulating part 4. Among them, the insulating part 4 is located between the mounting plate 2 and the inductor seal 3, that is, the insulating part 4 is fixedly installed on the mounting plate 2, and the inductor seal 3 is installed on the insulating part 4 corresponding to the mounting port 201. In this embodiment, the insulating part 4 can be an insulating epoxy board, which is rectangular in shape and is provided at the center position at the upper end of the mounting plate 2. Possibly, in order to achieve a higher sealing accuracy, the inductor seal 3 and the insulating part 4 can be directly adhered to the corresponding position of the mounting port 201 in the insulating part 4 by dotting back glue on the fitting surface between the inductor seal 3 and the insulating part 4.

[0029] In this embodiment, by providing the insulating member 4 as the isolation material during the installation of the inductor 1, it is beneficial to avoid current interference and short - circuit phenomena. Directly attaching the inductor seal 3 onto the insulating member 4 at the installation opening 201 at the corresponding position can improve the sealing degree and enhance the protection level.

[0030] Example 3

[0031] Combined Figures 1 - 2 As shown, in this embodiment, the installation opening 201 is provided in the upper part of the installation plate 2, and each installation portion 101 passes through the correspondingly provided installation opening 201. The installation openings 201 are arranged at equal intervals horizontally.

[0032] Specifically, the position for opening the installation opening 201 can be determined in combination with the size of the inductor 1 and the setting of the installation portion 101. For more stable installation, in this embodiment, the installation opening 201 is opened at the central position at the upper end of the installation plate 2. The installation portions 101 are arranged at equal intervals horizontally, and the corresponding installation openings 201 are also arranged at equal intervals horizontally, and the equal - interval settings of the installation portions 101 and the installation openings 201 are kept consistent, so as to ensure that the installation portions 101 can smoothly pass through the corresponding installation openings 201. Among them, the installation portion 101 can be strip - shaped. After installation, the tail is clamped in the installation opening 201, and the head extends towards the inner cabin. Setting the installation portion 101 as strip - shaped and the head extending towards the inner cabin increases the stress area of the contact surface, and thus can enhance the installation stability.

[0033] Example 4

[0034] In this embodiment, the inductor seal 3 is provided with an opening penetrating the installation portion 101, and the diameter of the opening is smaller than the diameter of the installation opening 201; the inductor seal 3 is an elastic member, and when the installation portion 101 passes through the installation opening 201, an interference fit is formed between the inductor seal 3 and the installation portion 101.

[0035] Specifically, the inductor seal 3 is an elastic member. For example, the material selected for the inductor seal 3 is rubber with a temperature range of - 60° to 300°. An opening is provided on the inductor seal 3, and the opening position corresponds to the position of the installation opening 201, so that when the installation portion 101 passes through the installation opening 201, it can smoothly enter the inner - cabin side. Since the inductor seal 3 is made of an elastic material, for high - precision sealing, the diameter of the opening of the inductor seal 3 can be smaller than the diameter of the installation opening 201 to ensure an interference fit between the contact surfaces of the inductor seal 3 and the installation portion 101, but at least ensure that the diameter of the opening allows the installation portion 101 to pass through. Among them, the inductor seal 3 is generally rectangular in shape, and the fitting width of each side on the insulating member 4 can be kept consistent to ensure the sealing strength of each side.

[0036] In this embodiment, the inductance seal 3 is selected as an elastic member, which is more conducive to ensuring an interference fit between the contact surface of the inductance seal 3 and the mounting portion 101 for internal and external isolation, improving the sealing accuracy, and further improving the dust and water protection performance of the energy storage converter, more effectively protecting against flying dust and rainwater from entering the power inner cabin of the energy storage converter, thereby enhancing the safety protection level of the energy storage converter and reducing the occurrence of electrical faults.

[0037] Example 5

[0038] Combined with Figure 3 As shown, in this embodiment, the insertion port 202 extends out on the side of the mounting opening 201 close to the inductor 1, and the mounting portions 101 of the inductor 1 are inserted into the insertion ports 202 at corresponding positions and penetrate to the other side of the mounting opening 201.

[0039] Specifically, on the side close to the inductor 1, each mounting opening 201 extends out an insertion port 202 towards the inductor 1 side. The insertion port 202 protrudes towards the inductor 1 direction. The mounting portion 101 of the inductor 1 is inserted from the insertion port 202 and penetrates to the inner cabin side of the mounting opening 201 until the tail of the mounting portion 101 is limited by the insertion port 202, reaching a fully fitted state.

[0040] In this embodiment, setting the insertion port 202 not only facilitates the insertion of the mounting portion 101, but also increases the assembly contact area of the mounting portion 101, thereby ensuring the stability of the insertion.

[0041] Example 6

[0042] Combined with Figures 1 - 2 As shown, in this embodiment, the insulating member 4 includes through holes corresponding to the mounting openings 201, and the insulating member 4 is fixedly connected to the mounting plate 2 through a plurality of connecting members 5 symmetrically arranged on the edge of the insulating member 4.

[0043] Specifically, in order to ensure that the mounting portion 101 smoothly penetrates the mounting opening 201 and enters the inner cabin side, through holes also need to be opened on the insulating member 4 for the mounting portion 101 to pass through. The diameter of the through holes of the insulating member 4 is kept consistent with the diameter of the mounting opening 201, which can not only ensure a higher isolation effect but also not hinder the installation of the mounting portion 101. Among them, the insulating member 4 can be fixedly installed on the mounting plate 2 through a plurality of connecting members 5 to ensure stability. For example: fixed by screws symmetrically arranged in two rows, upper and lower, on the edge of the insulating member 4, with 5 screws in each row.

[0044] In this embodiment, setting through holes on the insulating member 4 can ensure that the mounting portion 101 smoothly penetrates the mounting opening 201 and enters the inner cabin side, and fixing the insulating member 4 on the mounting plate 2 through a plurality of connecting members 5 can improve the installation stability.

The energy storage converter internally includes various electronic components, especially the inductor 1 component. In this embodiment, the energy storage converter includes an inductor mounting structure of the energy storage converter in the above embodiment. Since an inductor seal 3 is provided on the side of the mounting opening 201 of the mounting plate 2 facing away from the inductor 1, and the inductor seal 3 surrounds the periphery of the mounting opening 201. When the mounting portion 101 passes through the mounting opening 201 for installation, the surface in contact with the inductor seal 3 is extruded to form a tight contact, achieving a sealing fit. That is, the inductor seal 3 is used to isolate the inside and outside at the interface position where the inductor 1 is installed, improving the sealing accuracy, thereby improving the dust and waterproof performance of the energy storage converter, more effectively protecting the power inner cabin of the energy storage converter from flying dust and rainwater entering, thus enhancing the safety protection level of the energy storage converter and reducing the occurrence of electrical failures; in addition, compared with caulking, by directly setting the inductor seal 3 at the mounting opening 201 for sealing, the speed is faster and the production efficiency can be improved more.

When the mounting portion 101 passes through the mounting opening 201 for installation, the surface in contact with the inductor seal 3 is extruded to form a tight contact, achieving a sealed fit to realize internal and external isolation, improving the sealing accuracy, and further improving the dust and water protection performance of the energy storage converter. It can more effectively prevent flying dust and rainwater from entering the power inner cabin of the energy storage converter, thereby enhancing the safety protection level of the energy storage converter and reducing the occurrence of electrical faults. In addition, compared with applying glue to the mounting opening 201 in sequence, directly setting the inductor seal 3 on the mounting opening 201 for sealing is faster and can improve production efficiency. By providing the insulating member 4 as the isolation material when the inductor 1 is installed, it is beneficial to avoid current interference and short-circuit phenomena.
