Abstract
Description
Technical Field
[0001] This application relates to the field of automotive controller technology, and in particular to a housing sealing structure and controller for a controller. Background Technology
[0002] During the operation of an automotive generator controller, the housing sealing structure has a decisive impact on the controller's normal operation and long-term reliability. If the controller housing's sealing performance is substandard, it will lead to a series of serious technical problems. For example, moisture intrusion may cause short circuits or insulation failures, and in extreme cases, may even lead to leakage or fire accidents. Secondly, ambient humidity will accelerate the corrosion process of metal components, causing copper busbars to rust and connecting wire housings to age, thus significantly shortening the equipment's lifespan. Furthermore, dust intrusion and accumulation will block heat dissipation channels, causing components to overheat, and may also lead to oxidation of circuit contacts, thereby affecting the stability of signal transmission. Therefore, optimizing the housing sealing structure design is crucial to ensuring the reliable operation of the controller.
[0003] However, existing controller housings have significant technical defects when assembled with connectors. Because the controller's sealing structure has vertical walls, when sealant is applied to the vertical walls, the sealant will flow down under gravity. Furthermore, during assembly, the sealing edges of the connector will scrape off some residual sealant, resulting in insufficient sealant on the vertical walls. Ultimately, this leads to poor sealing due to difficulty in retaining sealant. Utility Model Content
[0004] In view of this, the purpose of this application is to provide a housing sealing structure and a controller for a controller, so as to solve the problem of poor sealing caused by the difficulty of leaving adhesive in the housing sealing structure of the existing controller.

[0030] like Figure 1 and Figure 2 As shown, according to a first aspect of the present invention, a housing sealing structure for a controller is provided, the housing sealing structure for a controller includes an upper housing seal 1, a lower housing seal 2, and a connector 3.
[0031] In the following description, reference will be made to Figure 1 and Figure 2 The specific structure of the aforementioned components and their connection relationships are described in detail in the housing sealing structure used in the controller.
[0032] like Figure 1 and Figure 2As shown, in this embodiment, the upper shell seal 1 can be disposed on the upper shell 4 of the controller, and the lower shell seal 2 can be disposed on the lower shell 5 of the controller. The connector 3 can be installed on the controller, passing through the upper shell 4 and the lower shell 5 when installed. When the upper shell 4 and the lower shell 5 are engaged, the upper shell seal 1 and the lower shell seal 2 can surround the outer periphery of the connector 3. A first adhesive reservoir 10 can be provided on the side of the upper shell seal 1 near the connector 3, and a second adhesive reservoir 20 can be provided on the side of the lower shell seal 2 near the connector 3. This arrangement allows the adhesive flowing onto the vertical wall surface to be stored in the first adhesive reservoir 10 and the second adhesive reservoir 20. After the connector 3 is installed, it can squeeze the adhesive in the first adhesive reservoir 10 and the second adhesive reservoir 20, causing the adhesive to flow back onto the vertical wall surface, thereby increasing the amount of adhesive on the vertical wall surface and ensuring the controller's sealing performance.
[0033] Preferred, such as Figure 1 and Figure 2 As shown, in this embodiment, the cross-section of the connector 3 can be approximately rectangular. To ensure that the first adhesive reservoir 10 and the second adhesive reservoir 20 can surround the connector 3 when it is installed on the controller, both the first adhesive reservoir 10 and the second adhesive reservoir 20 can be configured as semi-annular grooves. Therefore, when the upper housing 4 and the lower housing 5 are engaged, the first adhesive reservoir 10 can surround the upper half of the connector 3, and the second adhesive reservoir 20 can surround the lower half of the connector 3. The first adhesive reservoir 10 can communicate with the second adhesive reservoir 20.
[0034] Further optimized, such as Figure 1 and Figure 2 As shown, in this embodiment, the first adhesive reservoir 10 can be aligned with the second adhesive reservoir 20. That is, the width of the first adhesive reservoir 10 formed in the upper shell seal 1 is equal to the width of the second adhesive reservoir 20 formed in the lower shell seal 2, and the positions of the first adhesive reservoir 10 and the second adhesive reservoir 20 correspond to each other. When the upper shell 4 and the lower shell 5 are fastened together, the first adhesive reservoir 10 and the second adhesive reservoir 20 can be precisely fitted together to form a complete annular groove. This arrangement facilitates the flow of adhesive between the first adhesive reservoir 10 and the second adhesive reservoir 20, allowing the adhesive to be evenly coated.
[0035] Preferred, such as Figure 1 and Figure 2As shown, in this embodiment, an annular sealing portion 31 can be formed on the outer periphery of the connector 3, and the sealing portion 31 protrudes from the wall surface of the connector 3. When the upper housing 4 and the lower housing 5 are engaged, the position of the sealing portion 31 corresponds precisely to the position of the first glue reservoir 10 and the second glue reservoir 20. The width of the sealing portion 31 can be smaller than the width of the first glue reservoir 10 and the second glue reservoir 20, so that the sealing portion 31 can be inserted into the first glue reservoir 10 and the second glue reservoir 20 to squeeze the glue in the first glue reservoir 10 and the second glue reservoir 20, forcing the glue to flow back along the vertical wall surface.
[0036] Furthermore, preferably, such as Figure 1 As shown, in this embodiment, an annular groove 310 may be formed at the center of the sealing portion 31 in the width direction (i.e., the center in the axial direction), and the annular groove 310 may be coaxial with the sealing portion 31. The annular groove 310 may be recessed radially into the sealing portion 31. The annular groove 310 connects the first glue storage tank 10 and the second glue storage tank 20, allowing the glue in the first glue storage tank 10 and the second glue storage tank 20 to flow into the annular groove 310, thereby improving the sealing effect of the sealing portion 31.
[0037] Preferred, such as Figure 1 As shown, in this embodiment, the upper shell seal 1 can be integrally formed with the upper shell 4. The upper shell seal 1 may include a first protrusion 11 and a first boss 12, which are spaced apart. The first protrusion 11 may be located on the side of the upper shell seal 1 near the upper shell 4, and the first boss 12 may be located on the side of the upper shell seal 1 away from the upper shell 4. The first adhesive reservoir 10 is sandwiched between the first protrusion 11 and the first boss 12, i.e., the first adhesive reservoir 10 is formed by the first protrusion 11 and the first boss 12 sandwiching each other.
[0038] Similarly, such as Figure 1 As shown, in this embodiment, the lower shell seal 2 can be integrally formed with the lower shell 5. The lower shell seal 2 may include a second protrusion 21 and a second protrusion 22, which are spaced apart. The second protrusion 21 may be located on the side of the lower shell seal 2 near the lower shell 5, and the second protrusion 22 may be located on the side of the lower shell seal 2 away from the lower shell 5. The second adhesive reservoir 20 is sandwiched between the second protrusion 21 and the second protrusion 22, i.e., the second adhesive reservoir 20 is formed by the second protrusion 21 and the second protrusion 22 sandwiching each other.
[0039] Furthermore, preferably, such as Figure 1As shown, in this embodiment, a recessed portion 320 may be provided at the ends of the first boss 12 and the second boss 22 away from the controller. Correspondingly, a support portion 32 protruding from the wall surface of the connector 3 may be provided on the connector 3. The support portion 32 may be provided with reinforcing ribs, and when the upper housing 4 and the lower housing 5 are fastened together, the support portion 32 can be engaged in the recessed portion 320 to provide support for the connector 3.
[0040] In addition, such as Figure 1 and Figure 2 As shown, according to a second aspect of the present invention, a controller is provided, the controller including the housing sealing structure for a controller as described above.
[0041] During use, the upper shell seal 1 is provided with a first glue storage tank 10, and the lower shell seal 2 is provided with a second glue storage tank 20. This allows the glue flowing onto the vertical wall surface to be stored in the first glue storage tank 10 and the second glue storage tank 20. After the connector 3 is installed, the connector 3 can squeeze the glue in the first glue storage tank 10 and the second glue storage tank 20, causing the glue to flow back to the vertical wall surface, thereby increasing the amount of glue stored on the vertical wall surface and ensuring the seal of the controller.
[0042] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this application. Such modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be covered within the protection scope of this application. Therefore, the protection scope of this application should be determined by the protection scope of the claims.
