Description

Technical Field

[0001] This utility model relates to the field of dashboards, and in particular to a waterproof structure for automotive dashboards. Background Technology

[0002] The car's dashboard is the core display interface for vehicle status. It primarily contains a speedometer, tachometer, fuel gauge, and coolant temperature gauge. The dashboard connects to multiple sensors to detect information such as vehicle speed, engine speed, fuel level, and coolant temperature, and then displays this information on the dashboard.

[0003] Chinese patent application date: April 30, 2024, publication number: CN222223913U, discloses a waterproof automotive dashboard, including a dashboard body, a transparent cover, and a sealing strip disposed between the dashboard body and the transparent cover. The dashboard body has a receiving chamber in the middle, with a fixing body on the inner wall of the receiving chamber. The transparent cover has an elastic body that cooperates with the fixing body. The fixing body has an opening area in the middle, with symmetrically arranged blocking parts in the middle of the opening area. The elastic body consists of a connecting rod and a U-shaped part that cooperates with the opening area. This waterproof automotive dashboard has a compact structure and ingenious design. The transparent cover is installed onto the dashboard body by direct insertion, eliminating the need for external tools and reducing installation operations. This not only facilitates installation but also ensures better sealing performance of the entire dashboard, improving assembly efficiency.

[0004] In this technical solution, although the gap between the panel and the transparent cover can be sealed, a wiring harness is required between the instrument panel and the sensor. Gaps can easily appear between the wiring harness and the instrument panel, affecting the sealing effect of the instrument panel. Utility Model Content

Detailed Implementation

[0018] 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.

[0019] like Figures 1-4 As shown, a waterproof structure for an automotive instrument panel includes a enclosure frame 100, a transparent cover plate 200 at the top of the enclosure frame 100, and a base 300 fixed to the bottom of the enclosure frame 100 by screws. A rubber ring 400 is provided between the base 300 and the inner wall of the enclosure frame 100. The rubber ring 400 seals the gap between the enclosure frame 100 and the base 300. A wire pass-through port 500 is provided through the bottom of the base 300, and a sealing component 600 is inserted into the wire pass-through port 500. The wiring harness connected to the instrument panel passes through the wire pass-through port 500 and is limited by the sealing component 600, which also seals the wire pass-through port 500. A clamping component 700 is provided at the bottom of the base 300, clamping the sealing component 600 on both sides. The clamping component 700 prevents the sealing component 600 from detaching from the wire pass-through port 500.

[0020] In use, an annular support 101 is fixedly installed on the inner wall of the enclosure frame 100, and an annular mounting seat 102 is fixedly installed on the bottom edge of the annular support 101. A rubber ring 400 is disposed inside the annular mounting seat 102. The base 300 includes a boss 301, and a panel 302 is fixedly installed on the bottom of the boss 301. The boss 301 is inserted into the rubber ring 400 and the inner side of the annular support 101. The panel 302 fits against the bottom of the annular mounting seat 102 and the rubber ring 402, and is fixedly installed on the annular mounting seat 102 by screws. The boss 301 and the rubber ring 400 are interference-fitted, thereby sealing the gap between the annular mounting seat 102 and the boss 301 through the rubber ring 400.

[0021] In practice, a support block 501 is fixedly installed on the side wall of the wire hole 500. The cross-section of the support block 501 is a right trapezoid. The bottom end of the support block 501 extends to the lower side of the base 300. A first rubber sheet 502 is fixedly installed on the bottom and inclined surface of the support block 501.

[0022] Specifically, the sealing assembly 600 includes a mounting cover 601. Extension strips 602 are fixedly mounted on both ends of the mounting cover 601. An insert block 603 is fixedly mounted on the inner wall of the mounting cover 601. The insert block 603 has a right-angled trapezoidal cross-section and is inserted into the wire passage 500. A second rubber sheet 604 is fixedly mounted on the inner wall of the mounting cover 601 and the inclined surface of the insert block 603. Thus, the wire harness inside the wire passage 500 is clamped by the second rubber sheet 604 and the first rubber sheet 502. The first rubber sheet 502 and the second rubber sheet 604 deform and tightly adhere to the surface of the wire harness. In practice, a cable tray is provided on the opposite side of the first rubber sheet 502 and the second rubber sheet 604. The cross-section of the cable tray is semi-circular, ensuring that the first rubber sheet 502 and the second rubber sheet 604 tightly adhere to the surface of the wire harness, preventing gaps from appearing around the wire harness and between it and the first rubber sheet 502 and the second rubber sheet 604. The second rubber sheet 604 has side baffles 605 integrally formed on both the left and right sides of its bottom. The two side baffles 605 are respectively clamped on both sides of the bottom end of the support block 501. An arched rubber strip 606 is provided in the middle of the second rubber sheet 604. The insert block 603 is inserted between the second rubber sheet 604 and the arched rubber strip 606, and the arched rubber strip 606 is attached to the inner wall of the wire passage 500. Thus, the gap between the insert block 603 and the wire passage 500 is filled by the cooperation of the second rubber sheet 604 and the arched rubber strip 606.

[0023] In practice, the clamping assembly 700 includes a threaded rod 701 rotatably connected inside the base 300. A knob 702 is fixedly installed in the middle of the threaded rod 701. The threads of the left and right halves of the threaded rod 701 are in opposite directions. The bottom of the base 300 has four slide grooves 703 arranged in a matrix. Both ends of the threaded rod 701 extend into two of the slide grooves 703. The knob 702 protrudes from the bottom of the insert plate 302. The sealing assembly 600 has arched slides 704 on both sides. Both ends of the arched slides 704 are slidably connected to the two slide grooves 703. One end of the arched slide 704 is threadedly connected to the threaded rod 701. L-shaped buckles 705 are fixedly installed on opposite sides of the two arched slides 704. By turning the knob 702, the threaded rod 701 is rotated, thereby causing the two arched slides 704 to move closer to each other, so that the L-shaped buckles 705 are fastened onto the extension strip 602, thus limiting the sealing assembly 600.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
