Description

Technical Field

[0001] This application relates to the field of electrical waterproofing structures, and more particularly to a potted waterproof housing. Background Technology

[0002] While plastic casings for batteries and electrical appliances provide basic waterproof protection, their performance may not be sufficient to guarantee the safety and stability of the battery or appliance when subjected to prolonged underwater immersion.

[0003] To address this, the industry commonly uses encapsulation to improve the sealing of the casing. However, because the internal structures of batteries and electrical appliances typically contain irregular structures such as circuit boards and electrical components, these irregularities can hinder the flow of the encapsulation material, easily creating numerous voids. These voids trap air, and since air has poor thermal conductivity, these voids severely affect the heat dissipation performance of the battery or appliance, thereby impacting its lifespan and stability.

[0004] Therefore, how to reduce the voids inside the potting structure and ensure the uniformity of the potting to improve the heat dissipation effect is an urgent problem to be solved. Utility Model Content

[0005] This application provides a potting waterproof shell that can effectively improve the uniformity of potting, thereby improving the heat dissipation effect of batteries or electrical appliances.

[0006] The potting waterproof shell provided in this application adopts the following technical solution:

[0007] A waterproof enclosure for potting includes a housing, on which a potting port is provided, and at the center of the housing is a mounting area for installing electrical components. A guide plate is provided on one side of the mounting area, and the guide plate is fixedly connected to the housing.

[0008] The adhesive guide plate is inclined, with one side close to the installation area and the other side away from the installation area.

[0009] By adopting the above technical solution, during implementation, electrical components are first installed within the installation area, and then adhesive is injected into the housing through the dispensing port. Due to the inclined design of the dispensing guide plate, the adhesive is guided during its flow, resulting in a more even distribution within the installation area and close contact with the electrical components. This structure effectively reduces voids generated during dispensing, improves dispensing uniformity, and consequently enhances the heat dissipation of the battery or electrical appliance.

[0010] Preferably, the thickness of the adhesive guide plate on the side closer to the installation area is greater than the thickness on the side farther from the installation area.

[0011] By adopting the above technical solution, this structure can further guide the flow direction of the colloid, so that the colloid can adhere as closely as possible to the guide plate, reduce the gaps around the guide plate, and make the colloid more uniform.

[0012] Preferably, the guide plate has a guide surface on the side near the installation area, and the guide surface is parallel to the distribution direction of the installation area.

[0013] By adopting the above technical solution, the setting of the guide surface can further reduce the resistance of the adhesive during the flow process, ensuring that the adhesive can flow smoothly through the entire installation area, thereby improving the uniformity of the dispensing.

[0014] Preferably, the edges of the adhesive guide plate are rounded.

[0015] By adopting the above technical solution, the rounded design can prevent the colloid from forming sharp-angled gaps at the edge of the guide plate, thereby ensuring the uniformity of the colloid.

[0016] Preferably, the glue inlet includes a glue inlet and a glue outlet, and the glue inlet and the glue outlet form a glue inlet channel, which surrounds the periphery of the installation area.

[0017] By adopting the above technical solution, the positions of the glue inlet and outlet can be arbitrarily selected through this surrounding layout, allowing the glue to be injected evenly into the installation area from multiple directions, thereby greatly improving the uniformity of glue dispensing.

[0018] Preferably, multiple guide plates are provided and surround the periphery of the installation area.

[0019] By adopting the above technical solutions, the flow path of the colloid and the effect of uniform distribution can be further increased.

[0020] Preferably, the glue inlet and glue outlet are located on the same side of the housing.

[0021] By adopting the above technical solution, this design simplifies the complexity of the glue dispensing operation, allowing the glue to flow more smoothly from the glue inlet, through the installation area, and finally out from the glue outlet, thereby improving production efficiency. Furthermore, the fact that the glue inlet and the glue outlet are located on the same side of the housing facilitates subsequent sealing treatment and also improves the integrity and aesthetics of the housing.

[0022] Preferably, the adhesive guide plate is made of a thermally conductive material.

[0023] By adopting the above technical solution, the guide plate can not only guide the flow of the colloid, but also effectively conduct the heat generated by the battery or electrical appliance, further improving the heat dissipation performance.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Because this application uses an inclined guide plate, it can effectively guide the flow of the adhesive, reduce the voids generated during the dispensing process, thereby improving the uniformity of dispensing and improving the heat dissipation effect of the battery or electrical appliance;

[0026] 2. In this application, multiple surrounding guide plates and heat-conducting materials are preferably used to further improve the uniformity of potting and heat dissipation, ensuring that the battery or electrical appliance can maintain stable performance during long-term use.

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] Example 1

[0033] like Figure 1 The image shows the structure of a common waterproof enclosure with potting compound. It has an internal area for installing electrical components. During manufacturing, after the electrical components are installed inside the enclosure, potting compound is applied to the interior, and then the compound is allowed to air dry and solidify.

[0034] Reference Figure 2 The waterproof enclosure provided in this application includes a housing 1 with a dispensing port 12. The center of the housing 1 is designated as an installation area 11 for mounting electrical components. To improve the uniformity of the dispensing, a guide plate 2 is provided on one side of the installation area 11, and this guide plate 2 is fixedly connected to the housing 1. The guide plate 2 is inclined, with one side close to the installation area 11 and the other side away from it. This structure guides the adhesive to flow better and cover the entire installation area 11, and ensures that the adhesive can make close contact with the electrical components, further reducing gaps.

[0035] Specifically, the thickness of the adhesive guide plate 2 on the side closer to the installation area 11 is designed to be greater than the thickness on the side farther away from the installation area 11. This change in thickness can further guide the flow direction of the adhesive, and also allow the adhesive to adhere as closely as possible to the adhesive guide plate 2, reducing gaps around the adhesive guide plate 2 and making the adhesive more uniform.

[0036] Reference Figure 3 The guide plate 2 is also provided with a guide surface 21 on the side near the installation area 11. The guide surface 21 is parallel to the distribution direction of the installation area 11. The presence of the guide surface 21 can reduce the resistance of the adhesive during the flow process, making the dispensing more uniform.

[0037] In addition, the edges of the adhesive guide plate 2 are rounded to prevent sharp-angle gaps from forming at the edges of the adhesive guide plate 2, thus ensuring the uniformity of the adhesive.

[0038] Example 2

[0039] Based on Example 1, this example further optimizes the dispensing port. Specifically, refer to... Figure 2 The glue inlet 12 includes a glue inlet 121 and a glue outlet 122, which together form a glue inlet channel 23. This glue inlet channel 23 surrounds the periphery of the installation area 11. This surrounding layout allows the positions of the glue inlet 121 and the glue outlet 122 to be arbitrarily selected, enabling the glue to be injected evenly into the installation area 11 from multiple directions, thereby further improving the uniformity of glue dispensing.

[0040] Meanwhile, multiple guide plates 2 are also provided, surrounding the perimeter of the installation area 11. The multiple guide plates 2 increase the flow path of the adhesive, allowing it to be distributed more evenly in the installation area 11. It is worth mentioning that the inlet 121 and outlet 122 are designed on the same side of the housing 1. This layout not only simplifies the dispensing operation but also improves production efficiency. Furthermore, having the inlet 121 and outlet 122 on the same side of the housing 1 facilitates subsequent sealing and improves the overall integrity and aesthetics of the housing 1.

[0041] Example 3

[0042] Based on Embodiment 1 or Embodiment 2, the adhesive guide plate 2 in this embodiment is made of a thermally conductive material. The thermally conductive material can effectively conduct the heat generated by the battery or electrical appliance to the outer casing, thereby improving heat dissipation.

[0043] In summary, the waterproof casing of this application, through innovative designs such as setting an inclined glue guide plate, optimizing the glue filling port, and selecting thermally conductive materials, effectively improves the uniformity of glue filling and enhances the heat dissipation of the battery or electrical appliance. These embodiments fully demonstrate the practicality of this application and its significant improvement over the prior art.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
