Description

Technical Field

[0001] This utility model relates to the field of instrument technology, and in particular to a waterproof instrument panel structure. Background Technology

[0002] As a critical operating and display device in vehicles or equipment, the stability and reliability of the dashboard directly affect the user experience and the normal operation of the equipment. In practical use, dashboards typically face a variety of complex environmental factors, including rain intrusion, high humidity, and dust pollution. Especially in outdoor applications such as vehicles, ships, and industrial equipment, the waterproof performance of the dashboard is particularly important. A waterproof design can effectively prevent moisture from entering the interior, protecting electronic components, circuit boards, and sensors from corrosion or short circuits, thereby ensuring the long-term stable operation of the dashboard.

[0003] In the existing technology, some waterproof instrument panels achieve waterproofing by sealing the upper and lower housings with adhesive after they are joined. This is done by creating a sealant groove at the joint of the upper and lower housings and injecting sealant into the joint surface to form a sealed structure.

[0004] However, the inventors discovered during actual use that the glue easily overflows due to excessive or uneven application, affecting not only the appearance of the casing but also increasing cleaning costs. Glue overflow can also damage internal components of the dashboard. Therefore, there is an urgent need for a waterproof dashboard structure that can effectively solve the glue overflow problem, prevent glue spillage, and improve sealing performance. Utility Model Content

[0005] In view of at least one of the above technical problems, the present invention provides a waterproof instrument panel structure, which adopts an improved sealing structure to enhance sealing performance.

[0006] According to a first aspect of the present invention, a waterproof instrument panel structure is provided, comprising:

[0007] The bottom shell includes a bottom plate and a surrounding edge. The bottom plate has several through holes. The surrounding edge is divided into an outer plate and an inner plate. A sealing groove is formed between the two layers of the surrounding edge. The bottom shell has an accommodating chamber inside.

[0008] The top cover includes a panel and a sealing strip disposed on the outer periphery of the panel extending toward the sealing groove, the sealing strip extending into the sealing groove;

[0009] An electrical component is disposed inside the receiving cavity, the electrical component including a wiring harness that passes through the through-hole to the outside of the bottom shell;

[0010] The sealing groove and the sealing strip are filled with glue. The outer plate also has a flow guide groove on the side near the sealing groove. The flow guide groove is configured such that when the bottom shell and the top cover are closed, the bottom surface of the flow guide groove is horizontal with the end face of the sealing strip.

[0011] In some embodiments of this utility model, the bottom shell also has a fixing seat facing the interior of the receiving cavity, and the electrical component is fixedly connected to the fixing seat.

[0012] In some embodiments of this utility model, the bottom shell also has a fixing hole, and the electrical component has a connecting hole that is opposite to the fixing hole. The fixing hole and the connecting hole are fixed by a connector passing through them.

[0013] In some embodiments of this utility model, there is a 0.5mm gap between the through hole and the wire harness.

[0014] In some embodiments of this utility model, the height of the inner plate is higher than the height of the outer plate, and both the inner plate and the outer plate are configured to abut against the top cover.

[0015] In some embodiments of this utility model, the sealing strip and the inner plate are interference-fitted.

[0016] In some embodiments of this utility model, the sealing strip also has a locking component in the direction near the inner plate, including a locking member protruding from the sealing strip, a locking groove formed on the inner plate and disposed opposite to the locking member.

[0017] In some embodiments of this utility model, there is a gap between the outer plate and the sealing strip.

[0018] In some embodiments of this utility model, the end face of the outer plate that abuts against the top cover has a chamfer.

[0019] In some embodiments of this utility model, the adhesive is made of acrylic resin.

[0020] The beneficial effects of this utility model are as follows: By designing a guide groove on the side of the outer panel near the sealing groove, when the bottom shell and the top cover are closed, the bottom surface of the guide groove and the end face of the sealing strip remain horizontal, forming an effective guide path. This can guide excess glue into the guide groove during the glue injection process, preventing glue from overflowing to the outside and improving the overall sealing performance and appearance quality. The sealing groove set in the middle of the double-layer edging cooperates with the sealing strip of the top cover to further enhance the sealing effect and ensure the safety and stability of the internal electrical components in complex environments.

[0033] like Figures 1 to 7 The waterproof instrument panel structure shown includes:

[0034] The bottom shell 1 includes a bottom plate 11 and a surrounding edge 12. The bottom plate 11 has several through holes 11a. The surrounding edge 12 is divided into an outer plate 12a and an inner plate 12b. The middle of the double-layer surrounding edge 12 is a sealing groove 12b1. The bottom shell 1 has an accommodating chamber 13 inside. It should be noted that the bottom shell 1 can also have a sound hole. In order to make the sound hole waterproof, a waterproof and sound-permeable membrane can also be provided on the sound hole to achieve sealing.

[0035] The top cover 2 includes a panel 21 and a sealing strip 21a that extends outward from the outer periphery of the panel 21 toward the sealing groove 12b1. The sealing strip 21a extends into the sealing groove 12b1.

[0036] Electrical component 3 is disposed inside the receiving chamber 13. Electrical component 3 includes a wire harness that passes through the through hole 11a to the outside of the bottom shell 1.

[0037] Among them, glue 12b2 is injected between the sealing groove 12b1 and the sealing strip 21a. The outer plate 12a also has a guide groove 12a1 on the side near the sealing groove 12b1. The guide groove 12a1 is configured such that when the bottom shell 1 and the top cover 2 are closed, the bottom surface 12a2 of the guide groove 12a1 is horizontal with the end face 21b of the sealing strip 21a.

[0038] In the actual installation process of this utility model, glue 12b2 is first injected into the sealing groove 12b1. To improve the sealing effect of glue 12b2, glue 12b2 is slightly higher than the sealing groove 12b1. When the top cover 2 approaches the bottom shell 1 and the sealing strip 21a extends into the sealing groove 12b1, the sealing strip 21a squeezes the glue 12b2, causing the glue 12b2 to flow into the guide groove 12a1. Finally, when the top cover 2 and the bottom shell 1 are attached and the sealing strip 21a is fully inserted into the sealing groove 12b1, the glue 12b2 in the sealing groove 12b1 makes the sealing strip 21a stick to the sealing groove 12b1. The excess glue 12b2 in the sealing groove 12b1 flows into the guide groove 12a1.

[0039] This invention designs a flow guide groove 12a1 on the side of the outer plate 12a near the sealing groove 12b1. When the bottom shell 1 and the top cover 2 are closed, the bottom surface 12a2 of the flow guide groove 12a1 is level with the end face 21b of the sealing strip 21a, forming an effective flow guide path. This guides excess glue 12b2 into the flow guide groove 12a1 during the glue injection process, preventing glue 12b2 from overflowing to the outside and improving the overall sealing performance and appearance quality. The sealing groove 12b1 in the middle of the double-layer edging 12 cooperates with the sealing strip 21a of the top cover 2 to further enhance the sealing effect and ensure the safety and stability of the internal electrical components 3 in complex environments.

[0040] like Figure 4 , Figure 5 As shown, the bottom shell 1 also has a fixing seat 14 facing the interior of the receiving chamber 13, and the electrical component 3 is fixedly connected to the fixing seat 14. By setting the fixing seat 14 facing the interior of the receiving chamber 13 and fixing the electrical component 3 to the fixing seat 14, the installation stability of the electrical component 3 is effectively improved, and the loosening or displacement of the electrical component 3 due to vibration or external impact is avoided. It should be noted that the fixing seat 14 can be fixed by a nut, riveting, or other connection methods that can be used for fixing.

[0041] Continue to refer to Figure 4 , Figure 5 As shown, to ensure a more secure connection between the electrical component 3 and the base shell 1, the base shell 1 also has a fixing hole 15. The electrical component 3 has a connecting hole opposite to the fixing hole 15. A connector passes through the fixing hole 15 and the connecting hole for fixation. The connector passes through the fixing hole 15 and the connecting hole, thus securing the electrical component 3 to the base shell 1 and achieving stability. It should be noted that the number of fixing holes 15, connecting holes, and connectors can be increased or decreased according to actual needs. To improve the waterproof effect of the mounting base 15, adhesive can be injected between the fixing hole 15 and the connector in the connecting hole for sealing, or a sealing plug can be installed on the fixing hole 15 for sealing.

[0042] like Figure 2 , Figure 4 , Figure 5 As shown, there is a 0.5mm gap between the through hole 11a and the wire harness. By designing a 0.5mm gap between the through hole 11a and the wire harness, direct contact between the wire harness and the through hole 11a is effectively avoided, reducing the risk of damage to the wire harness due to mechanical friction or vibration. To achieve a seal between the through hole 11a and the wire harness, adhesive can be applied between them to achieve the seal.

[0043] like Figure 2 , Figure 3 , Figure 5 As shown, the inner plate 12b is higher than the outer plate 12a, and both the inner plate 12b and the outer plate 12a are configured to abut against the top cover 2. By designing the inner plate 12b to be higher than the outer plate 12a, and ensuring that both the inner plate 12b and the outer plate 12a abut against the top cover 2, the sealing performance is effectively improved. The double-layer plate arrangement forms a labyrinth-type seal, providing a double contact surface during sealing, further enhancing the structural stability and sealing effect, while reducing the risk of seal failure due to external pressure or deformation.

[0044] In some embodiments of this utility model, the sealing strip 21a and the inner plate 12b are interference-fitted. By designing the sealing strip 21a and the inner plate 12b as an interference fit, the fixation of the sealing strip 21a in the structure is enhanced. This not only ensures a tight fit between the sealing strip 21a and the inner plate 12b, improving the overall sealing performance, but also avoids sealing failure caused by a loose connection, thereby further improving the waterproof, dustproof, and reliability capabilities of the instrument panel.

[0045] In some embodiments of this utility model, the sealing strip 21a also has a locking component in the direction near the inner plate 12b, including a locking member protruding from the sealing strip 21a, a locking groove formed on the inner plate 12b, and a locking groove disposed opposite to the locking member. By providing a locking component in the direction near the inner plate 12b of the sealing strip 21a, including a protruding locking member and a locking groove disposed opposite to it, reliable locking between the sealing strip 21a and the inner plate 12b is achieved, further enhancing the fixing effect of the sealing strip 21a, preventing it from falling off or shifting due to external force or vibration during use, and ensuring that the sealing strip 21a always remains in the correct position.

[0046] like Figure 3 As shown, there is a gap between the outer panel 12a and the sealing strip 21a. The gap allows air in the sealing groove 12b1 to be discharged through the gap when the top cover 2 and the bottom shell 1 are in contact, and the glue 12b2 also flows out through the gap, thus preventing the glue 12b2 from flowing into the receiving chamber 13 and contaminating the internal components.

[0047] like Figure 6 As shown, the end face 21b of the outer panel 12a that abuts against the top cover 2 has a chamfer 12a3. By designing the chamfer 12a3 on the end face 21b of the outer panel 12a that abuts against the top cover 2, the direct conflict between the top cover 2 and the end face 21b of the outer panel 12a during installation is effectively reduced, lowering the risk of jamming during assembly. This chamfer 12a3 design not only improves the fit between the top cover 2 and the outer panel 12a.

[0048] In some embodiments of this invention, the adhesive 12b2 is made of acrylic resin. Using acrylic resin as the sealant 12b2 provides excellent adhesion and weather resistance, maintaining a stable sealing effect over a long period in complex environments. Acrylic resin also possesses good anti-aging properties and resistance to high and low temperatures, maintaining the elasticity and strength of the sealant under different temperature and humidity conditions, thereby preventing seal failure due to environmental changes.

[0049] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
