Description

Technical Field

[0001] This utility model relates to the technical field of controller chambers, and in particular to a controller chamber with a sealed structure. Background Technology

[0002] The existing controller chamber mainly consists of a base, a back cover, sealant, and screws. Its sealing function is mainly achieved by applying sealant to the back cover and then assembling it with the base. Through the curing and bonding of the sealant, the gap between the base and the back cover is filled, thus achieving a sealing effect.

[0003] However, sealing the base and back cover with sealant also has certain drawbacks. First, the bonding surfaces of the back cover and base need to be pre-treated (degreasing and dust removal) before applying the sealant, usually using plasma cleaning, which can damage the controller inside the base. Second, the curing time and intervals between applications of the sealant are relatively long, which cannot meet production cycle requirements. Finally, the airtightness of the controller chamber needs to be checked after applying the sealant. Testing before the sealant is fully cured can cause the sealant to shift under air pressure, resulting in poor airtightness and leakage during subsequent use.

[0004] Therefore, sealing the base and back cover with sealant presents many inconveniences during the sealing operation and testing process. Utility Model Content

[0005] The purpose of this invention is to provide a controller chamber with a sealed structure to alleviate the technical problems in the prior art where sealing the base and back cover with sealant often results in long sealing operation time and poor airtightness due to sealant displacement during testing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, the present invention provides a controller chamber with a sealed structure, including a base and a cover plate, wherein the cover plate covers the base so that a controller chamber is formed between the base and the cover plate;

[0008] The base has a first connecting part on its top circumferentially and a second connecting part on the outer edge of the cover plate. The second connecting part is connected to the first connecting part by laser welding to seal the controller chamber.

[0009] Furthermore, the side of the first connecting portion facing the second connecting portion is designated as the first mounting surface;

[0010] The side of the second connecting part facing the first connecting part is designated as the second mounting surface. The second mounting surface is parallel to the first mounting surface and is connected by laser welding.

[0011] Furthermore, the top of the first assembly surface is provided with a first slope, which is inclined in a direction away from the cover plate;

[0012] The top of the second assembly surface is provided with a second slope, which is inclined in a direction away from the first slope.

[0013] Furthermore, the first slope and the second slope have the same inclination angle, and a V-shaped annular groove is formed between the first slope and the second slope.

[0014] Furthermore, the top of the base is provided with a first rib along the circumferential direction. The first rib is located inside the first connecting part, and the top of the first rib supports the cover plate.

[0015] Furthermore, an annular groove is formed between the first rib and the first connecting portion.

[0016] Furthermore, the bottom of the second connecting part is provided with a second protruding rib, the second protruding rib is a ring structure, and the second protruding rib is located between the first connecting part and the first protruding rib.

[0017] Furthermore, there is a gap between the bottom of the second rib and the bottom surface of the groove.

[0018] Furthermore, the side of the second rib facing the first connecting portion is set as an inclined surface, and the inclined surface is inclined inward in a direction away from the first connecting portion.

[0019] Furthermore, the side of the second rib facing the first rib is set as an arc-shaped surface, and there is a gap between the arc-shaped surface and the first rib.

[0020] This utility model can achieve the following beneficial effects:

[0021] In a first aspect, the present invention provides a controller chamber with a sealed structure, including a base and a cover plate, the cover plate covering the base so that a controller chamber is formed between the base and the cover plate; the top of the base is provided with a first connecting part along the circumferential direction, and a second connecting part is provided along the outer edge of the cover plate, the second connecting part and the first connecting part being connected by laser welding to seal the controller chamber.

[0022] In this utility model, the top of the base is provided with a controller placement part, and the top of the base is surrounded by a first connecting part along the circumference of this placement part. The first connecting part forms a wall structure relative to the controller placement part. The cover plate is placed on the top of the base to close the top of the controller placement part, thereby forming a closed controller chamber. Then, the inner surface of the first connecting part and the outer surface of the second connecting part are laser welded together, that is, the base and the cover plate are welded along the circumference at the gap between the first connecting part and the second connecting part to achieve the sealing of the controller chamber.

[0023] Compared with existing technologies, the controller chamber with a sealed structure provided by this utility model achieves sealing of the controller chamber formed after the top cover and base are connected by laser welding the first connecting part of the base and the second connecting part of the cover plate.

[0039] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] Example 1

[0041] This embodiment provides a controller chamber with a sealed structure, as shown in the reference. Figure 1 , Figure 3 and Figure 4 The controller chamber with a sealed structure includes a base 1 and a cover plate 2. The cover plate 2 covers the base 1 so that a controller chamber is formed between the base 1 and the cover plate 2. The top of the base 1 is provided with a first connecting part 11 along the circumferential direction, and a second connecting part 21 is provided along the outer edge of the cover plate 2. The second connecting part 21 is connected to the first connecting part 11 by laser welding to seal the controller chamber.

[0042] This utility model embodiment at least alleviates the technical problems existing in the prior art, such as the long sealing operation time and poor airtightness caused by the displacement of the sealant during testing, when sealing the base and back cover with sealant.

[0043] In this embodiment of the utility model, the top of the base 1 is provided with a controller placement part, and the top of the base 1 is surrounded by a first connecting part 11 along the circumference. The first connecting part 11 forms a wall structure relative to the controller prevention part. The cover plate 2 covers the top of the base 1 to close the top of the controller placement part, thereby forming a closed controller chamber. Then, by laser welding the inner surface of the first connecting part 11 to the outer surface of the second connecting part 21, that is, by welding the base 1 and the cover plate 2 along the circumference at the gap between the first connecting part 11 and the second connecting part 21, the controller chamber is sealed.

[0044] Compared with the prior art, the controller chamber with a sealed structure provided in this embodiment of the utility model achieves sealing of the controller chamber formed after the cover plate 2 and the base 1 are connected by laser welding the first connecting part 11 of the base 1 and the second connecting part 21 of the cover plate 2. Compared with the existing method of using sealing rubber, leakage will not occur due to the displacement of the sealant, and the sealing preparation time and sealing operation time will be shortened.

[0045] In an optional implementation of this embodiment, refer to Figure 5 and Figure 6 The side of the first connecting part 11 facing the second connecting part 21 is designated as the first mounting surface 113; the side of the second connecting part 21 facing the first connecting part 11 is designated as the second mounting surface 213. The second mounting surface 213 and the first mounting surface 113 are distributed in parallel and connected by laser welding.

[0046] Specifically: the first mounting surface 113 is the inner surface of the first connecting part 11, and the first mounting surface 113 is preferably distributed in the vertical direction. Correspondingly, the second mounting surface 213, which is the outer surface of the second connecting part 21, is parallel to the first mounting surface 113. In use, the user can slightly adjust the position of the cover plate 2 so that the gap between the first mounting surface 113 and the second mounting surface 213 is equal at each position. Then, by laser welding, the first connecting part 11 and the second connecting part 21 melt due to their aluminum material after being heated. The molten aluminum fills the gap between the first mounting surface 113 and the second mounting surface 213, and then solidifies upon cooling to achieve a seal at the gap.

[0047] Furthermore, referring to Figure 2 and Figure 4 The top of the first assembly surface 113 is provided with a first slope 111, which is inclined in the direction away from the cover plate 2; the top of the second assembly surface 213 is provided with a second slope 211, which is inclined in the direction away from the first slope 111.

[0048] Specifically: the first ramp 111 and the second ramp 211 are distributed opposite to each other to form a groove structure between the first connecting part 11 and the second connecting part 21; in use, laser welding is performed at this groove, and after the structure is preheated and melted into molten aluminum, it will flow along the ramp into the gap between the first assembly surface 113 and the second assembly surface 213.

[0049] Furthermore, referring to Figure 4 The first slope 111 and the second slope 211 have the same inclination angle, and a V-shaped annular groove is formed between the first slope 111 and the second slope 211.

[0050] Specifically: the first ramp 111 and the second ramp 211 have the same inclination angle and are inclined in opposite directions, so that the molten aluminum will not be deflected due to the different inclination angles of the two ramps. That is, the isosceles V-shaped annular groove can make the molten aluminum flow vertically into the gap between the first assembly surface 113 and the second assembly surface 213.

[0051] In an optional implementation of this embodiment, refer to Figure 5 The top of the base 1 is also provided with a first protruding rib 12 along the circumferential direction. The first protruding rib 12 is located inside the first connecting part 11, and the top of the first protruding rib 12 supports the cover plate 2.

[0052] Specifically: the top of the first rib 12 is supported on the bottom surface of the cover plate 2, so that the top surface 22 of the cover plate 2 is flush with the upper end surface 112 of the first connecting part 11, thereby making the first slope 111 and the second slope 211 relatively distributed.

[0053] Furthermore, referring to Figure 4 and Figure 5 An annular groove 13 is provided between the first protruding rib 12 and the first connecting part 11.

[0054] Specifically: there is a gap between the first rib 12 and the first connecting part 11 to form a groove 13, and the groove 13 is distributed circumferentially along the top of the first connecting part 11; in use, the groove 13 is provided so that the molten aluminum remains in the groove 13 after flowing through the gap between the first mounting surface 113 and the second mounting surface 213, thus preventing the molten aluminum from flowing directly into the controller cavity.

[0055] Furthermore, referring to Figure 4 and Figure 6 The bottom of the second connecting part 21 is provided with a second protruding rib 212, which is a ring structure and is located between the first connecting part 11 and the first protruding rib 12.

[0056] Specifically: After the cover plate 2 is placed on the first rib 12, the annular second rib 212 of the cover plate 2 is inserted into the annular groove 13. The second rib 212 cooperates with the first rib 12 to form a labyrinth structure, which can better prevent the molten aluminum from entering the controller chamber.

[0057] Furthermore, referring to Figure 4 There is a gap between the bottom of the second rib 212 and the bottom surface of the groove 13.

[0058] Specifically: After the cover plate 2 is placed on the first rib 12, there is a gap between the second rib 212 and the bottom surface of the groove 13, so as to avoid the problem that the cover plate 2 will lift up after being placed due to the second rib 212 abutting against the groove 13 because of dimensional errors in the production of the cover plate 2 and the base 1.

[0059] In an optional implementation of this embodiment, refer to Figure 6 The side of the second rib 212 facing the first connecting part 11 is set as an inclined surface 2121, and the inclined surface 2121 is inclined inward in the direction away from the first connecting part 11.

[0060] Specifically: The inclined surface 2121 at the bottom of the second rib 212 can increase the volume of the groove 13 while blocking the molten aluminum, so that the groove 13 can hold more molten aluminum and prevent it from flowing into the controller cavity due to excessive molten aluminum.

[0061] In an optional implementation of this embodiment, refer to Figure 6 The side of the second rib 212 facing the first rib 12 is set as an arc surface 2122, and there is a gap between the arc surface 2122 and the first rib 12.

[0062] Specifically: the side of the second rib 212 facing the first rib 12 is set as an arc surface 2122, so that the gap between the second rib 212 and the first rib 12 has a larger capacity, so that the molten aluminum can have a larger space to accommodate after flowing through the gap between the second rib 212 and the groove 13, thus preventing the molten aluminum from eventually flowing into the controller cavity.

[0063] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Similar or identical parts between embodiments can be referred to mutually. The above embodiments in this specification are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of this utility model.
