Description

Technical Field

[0001] This utility model relates to the field of electric vehicle instrument technology, specifically a waterproof instrument structure with an adhesive potting structure. Background Technology

[0002] With the rapid development of electric vehicles for home use, the functions of electric vehicle instruments are becoming increasingly complex, leading to higher costs. However, because the instruments are exposed components, they are easily damaged by water, especially during the rainy season, causing malfunctions. Therefore, improvements are needed to address these issues.

[0003] Existing technology, such as publication number CN220023365U, provides a waterproof instrument structure with a potting compound, including a top cover, a bottom shell, and a liner. The top cover, liner, and bottom shell are connected sequentially. A PCBA board area is provided between the liner and the bottom shell, and the PCBA board area mates with the liner. A wire harness connector is provided inside the bottom shell, and the wire harness connector mates with the PCBA board area. Potting compounds are provided inside both the liner and the bottom shell, and these potting compounds mate with the top cover, liner, PCBA board area, and bottom shell, respectively. This utility model, by providing potting compounds inside the liner and bottom shell, effectively seals the PCBA board and wire harness connector inside the instrument, preventing the intrusion of moisture and dust, and improving the waterproof performance and service life of the instrument.

[0004] This solution involves filling a liner with adhesive in a liner potting groove to form an adhesive layer, sealing the gap between the liner and the PCBA board area to prevent moisture, dust, and other impurities from entering. Similarly, filling a bottom shell potting groove forms a bottom shell potting layer, sealing the gap between the bottom shell and the top cover. This ensures the entire instrument structure is fully sealed, achieving a waterproof effect. However, in actual use, care must be taken with the amount of adhesive filled during the potting process. The potting groove must be completely filled without overflowing excessively, which could affect the installation of subsequent components. Furthermore, the adhesive may shrink during curing, potentially creating voids within the potting groove and compromising the seal. Therefore, we propose a waterproof instrument structure with an integrated potting mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof instrument structure with a glue-filling structure. This waterproof instrument structure with a glue-filling structure solves the problem that the glue may shrink to a certain extent during the curing process, which can easily lead to gaps in the glue-filling tank and affect the sealing performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A waterproof instrument structure with an adhesive potting structure includes a lower housing, and an upper housing is spliced ​​to the top of the lower housing;

[0008] The top of the lower housing is provided with a glue-filling groove, and a sealing protrusion is fixedly connected to the bottom of the upper housing at the position corresponding to the glue-filling groove.

[0009] Preferably, a sealing slip ring is slidably connected to the inner wall of the glue-filling tank, and a first spring sheet is fixedly connected between the inner wall of the glue-filling tank and the sealing slip ring.

[0010] Preferably, an air injection groove is provided at the top of the lower housing, located within the inner ring of the glue-filling groove, and the air injection groove communicates with the interior of the glue-filling groove through an air hole.

[0011] Preferably, there are four sets of air holes, and the air holes are located below the sealing slip ring. The four sets of air holes are respectively located at the four corners of the lower housing between the air injection groove and the glue filling groove.

[0012] Preferably, a sliding groove is provided at the bottom of the upper housing corresponding to the position of the air injection groove, a pressure block is slidably connected to the inner wall of the sliding groove, and a second spring sheet is fixedly connected between the inner wall of the sliding groove and the pressure block.

[0013] Preferably, lower connecting blocks are fixedly connected to both sides of the lower housing, and upper connecting blocks are fixedly connected to both sides of the upper housing at positions corresponding to the two lower connecting blocks. Connecting holes are opened on both sides of the inner walls of the upper and lower connecting blocks for inserting screws.

[0014] Preferably, the top of the lower housing is provided with a mounting groove, and the bottom of the upper housing is provided with a mounting groove.

[0015] By employing the above technical solution, this utility model provides a waterproof instrument structure with an adhesive potting structure. It possesses at least the following beneficial effects:

[0016] I. This utility model features a glue-filling groove in the lower housing. Sealant is injected into this groove to fill the gap between the lower and upper housings, ensuring a waterproof seal. A sealing protrusion is positioned on the upper housing corresponding to the glue-filling groove. When the lower and upper housings are joined, the sealing protrusion embeds into the glue-filling groove, allowing the sealant to be more evenly distributed within the groove under pressure from the sealing protrusion, further ensuring a tight seal. Furthermore, a sealing slip ring on the inner wall of the glue-filling groove continuously applies pressure to the sealant under the tension of a first spring, preventing shrinkage during curing that could create air bubbles and compromise the seal.

[0017] Second, when the lower shell and the upper shell are spliced ​​together, the pressure block under the upper shell will also be embedded in the interior of the slide groove. As the pressure block enters the interior of the slide groove, the air inside the slide groove will be injected into the glue filling groove through the air hole. The injected air will squeeze the sealing slip ring, so that the sealant between the sealing slip ring and the sealing convex ring is squeezed more tightly to ensure the sealing effect.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] A waterproof instrument structure with a potting compound, such as Figure 1 - Figure 4 As shown, it includes a lower housing 1, an upper housing 2 is spliced ​​to the top of the lower housing 1, a glue-filling groove 11 is provided on the top of the lower housing 1, a sealing protrusion ring 21 is fixedly connected to the bottom of the upper housing 2 at the position corresponding to the glue-filling groove 11, a sealing slip ring 12 is slidably connected to the inner wall of the glue-filling groove 11, and a first spring sheet 13 is fixedly connected between the inner wall of the glue-filling groove 11 and the sealing slip ring 12.

[0026] In this embodiment, a glue-filling groove 11 is provided in the lower housing 1. Sealant is injected into the glue-filling groove 11 to fill the gap between the lower housing 1 and the upper housing 2, thereby ensuring a waterproof seal. A sealing protrusion 21 is provided in the upper housing 2 at the position corresponding to the glue-filling groove 11. When the lower housing 1 and the upper housing 2 are spliced, the sealing protrusion 21 is embedded in the glue-filling groove 11. When the sealant injected into the glue-filling groove 11 is squeezed by the sealing protrusion 21, the sealant is filled more evenly inside the glue-filling groove 11, thus ensuring its seal. Furthermore, the sealing slip ring 12 on the inner wall of the glue-filling groove 11 always applies a certain pressure to the sealant under the tension of the first spring sheet 13, so as to prevent the sealant from shrinking during the curing process, which would cause air bubbles in the sealant and affect the seal.

[0027] like Figure 3 , Figure 4 As shown, preferably, an air injection groove 14 is provided at the top of the lower housing 1 at the position of the inner ring of the glue filling groove 11. The air injection groove 14 is connected to the interior of the glue filling groove 11 through air holes 141. There are four sets of air holes 141, and the air holes 141 are located below the sealing slip ring 12. The four sets of air holes 141 are respectively located at the four corners of the lower housing 1 between the air injection groove 14 and the glue filling groove 11. A sliding groove 22 is provided at the bottom of the upper housing 2 at the position corresponding to the air injection groove 14. A pressure block 24 is slidably connected to the inner wall of the sliding groove 22. A second spring sheet 23 is fixedly connected between the inner wall of the sliding groove 22 and the pressure block 24.

[0028] In this embodiment, when the lower housing 1 and the upper housing 2 are spliced, the pressure block 24 below the upper housing 2 will also be embedded in the interior of the slide groove 22. As the pressure block 24 enters the interior of the slide groove 22, the air inside the slide groove 22 will be injected into the glue filling groove 11 through the air hole 141. The injected air will squeeze the sealing slip ring 12, so that the sealant between the sealing slip ring 12 and the sealing protrusion ring 21 will be squeezed more tightly to ensure the sealing effect.

[0029] like Figure 1 , Figure 2 As shown, preferably, lower connecting blocks 31 are fixedly connected to both sides of the lower housing 1, and upper connecting blocks 32 are fixedly connected to both sides of the upper housing 2 at the positions corresponding to the two lower connecting blocks 31. Connecting holes 33 are opened on both sides of the inner walls of the upper connecting blocks 32 and the lower connecting blocks 31 for inserting screws. The top of the lower housing 1 is provided with a mounting groove 4, and the bottom of the upper housing 2 is provided with a mounting groove 4 for installing PCBA boards.

[0030] In this embodiment, after the lower shell 1 and the upper shell 2 are spliced ​​together, they are fixed by screwing screws into the corresponding connecting holes 33 on the upper connecting block 32 and the lower connecting block 31.

[0031] This utility model discloses a waterproof instrument structure with a glue-filling mechanism. In use, before the lower housing 1 and upper housing 2 are joined, sealant is injected into the glue-filling groove 11 to fill the gap between the lower housing 1 and upper housing 2, ensuring a waterproof seal. Furthermore, by setting a sealing protrusion 21 on the upper housing 2 corresponding to the glue-filling groove 11, the sealing protrusion 21 embeds into the glue-filling groove 11 during the joining process. This allows the sealant injected into the glue-filling groove 11 to be more evenly filled inside the groove 11 under the pressure of the sealing protrusion 21, ensuring a tight seal. Additionally, the inner wall of the glue-filling groove 11 is sealed with a sliding ring 1. 2 will always apply a certain pressure to the sealant under the tension of the first spring plate 13, and when the lower shell 1 and the upper shell 2 are spliced, the pressure block 24 under the upper shell 2 will also be embedded in the interior of the slide groove 22. As the pressure block 24 enters the interior of the slide groove 22, the air inside the slide groove 22 will be injected into the glue filling groove 11 through the air hole 141. The injected air will squeeze the sealing slip ring 12, making the sealant between the sealing slip ring 12 and the sealing protrusion ring 21 more compact to ensure the sealing effect. After the lower shell 1 and the upper shell 2 are spliced, they are fixed by screwing screws into the corresponding connection holes 33 on the upper connecting block 32 and the lower connecting block 31.
