Description

Technical Field

[0001] This utility model relates to the field of sealing technology for the engine cover of a transport vehicle, specifically a sealing structure for the engine cover of a transport vehicle. Background Technology

[0002] The engine compartment of a transport truck is located below the cab at the front. To prevent rainwater, dust and other impurities from entering the engine compartment during vehicle operation, a cover is hinged to the outside of the engine compartment. A sealing strip is snapped and fixed to the inner edge of the cover. When the cover is closed on the engine compartment, the sealing strip can improve the airtightness of the engine compartment. Sealing strips are mainly made of rubber and other materials. Prolonged exposure to harsh environments (such as high temperature, low temperature, ultraviolet rays, rain, etc.) will cause them to age. Therefore, users sometimes purchase sealing strips to replace the aged ones themselves. Since the sealing strip is installed on the bottom of the cover, users need to remove the aged sealing strip first under the opened cover, and then lift the new sealing strip and look up at the groove of the sealing strip to align it with the groove for replacement. The traditional sealing structure is not very convenient for replacing sealing strips, and working under the movable sealing cover is not conducive to improving the safety of replacing sealing strips. Utility Model Content

[0003] The purpose of this utility model is to provide a sealing structure for the engine cover of a transport vehicle to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A sealing structure for a transport vehicle hood includes: The mounting bracket is rotatably mounted on the bottom of the sealing cover, and a mounting groove is provided through the middle of the mounting bracket, with one end of the mounting groove extending through one end of the mounting bracket; A sealing strip is snapped into the inside of the mounting groove. The sealing strip includes a first strip, which is arranged inside the mounting groove. The top and bottom of the first strip are fixed with second strips, which are respectively attached to the top and bottom surfaces of the mounting frame.

[0005] Furthermore, the mounting bracket is shaped like an inverted triangle to fit the edge of the sealing cover, and hinges are installed at both ends of the mounting bracket and the sealing cover.

[0006] Furthermore, the depth of the mounting groove is greater than the thickness of the adhesive strip.

[0007] Furthermore, two limiting strips are fixed on the top and bottom surfaces of one end of the mounting bracket, and the limiting strips can restrict the position of the second adhesive strip at the end of the mounting bracket.

[0008] Furthermore, one end of the sealing strip has a notch, which is engaged with the end of the mounting bracket near the limiting strip.

[0009] Furthermore, the first adhesive strip is a long strip with a rectangular cross-section, and the second adhesive strip has an elliptical hole through its middle.

[0010] Furthermore, the materials of the first and second rubber strips are EPDM rubber or PVC, one of the second rubber strips abuts against the inner edge of the cabin, and the other of the second rubber strips abuts against the inner edge of the sealing cover.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By hinged to the bottom of the sealing cover, a mounting bracket is used to indirectly install the sealing strip between the sealing cover and the engine compartment. During the replacement of the sealing strip, the engine cover is first opened, and then the mounting bracket on the bottom of the engine cover is rotated and unfolded, so that the mounting bracket can expose the aged sealing strip on the outside of the sealing cover. This allows users to directly replace the sealing strip on the outside of the sealing cover, eliminating the need for users to remove the aged sealing strip from the bottom of the sealing cover because the traditional sealing strip is fixed to the bottom of the sealing cover, and to lift the new sealing strip and look up at the groove of the strip to align it with the groove for replacement. This greatly improves the convenience of sealing strip installation.

[0012] By shifting the traditional process of replacing the sealing strip from below the sealing cap to the outside of the sealing cap, not only is the viewing angle for replacing the sealing strip expanded, but it can also effectively prevent safety accidents caused by accidental opening and closing of the sealing cap, thus improving the safety of sealing strip installation.

[0013] By designing the central strip of the sealing strip as a long strip, the entire sealing strip can be easily snapped into the mounting groove of the mounting bracket. Furthermore, by designing the top and bottom strips of the sealing strip as long strips with internal oval holes, when the sealing cover is closed on the engine compartment, one long strip can abut against the inside of the engine compartment, maintaining a seal between the engine compartment and the mounting bracket, while the other long strip can abut against the inside of the sealing plate, maintaining a seal between the sealing plate and the mounting bracket. This ensures a seal between the engine compartment and the sealing plate. Additionally, the central hole structure of the second strip allows it to elastically deform under pressure, filling the tiny gaps between the hood and the vehicle body, thus achieving a better sealing effect.

[0016] 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.

[0017] Example 1, please refer to Figure 1 - Figure 5 In this embodiment of the present invention, a sealing structure for a transport vehicle cover includes a mounting bracket 100 that is rotatably hinged to the sealing cover. A mounting groove 110 is provided through the middle of the mounting bracket 100. One end of the mounting groove 110 passes through one end of the mounting bracket 100. A sealing strip 200 is snapped into the inside of the mounting groove 110. The sealing strip 200 includes a first strip 210 arranged inside the mounting groove 110. A second strip 220 is fixed to the top and bottom of the first strip 210. The two second strips 220 are respectively attached to the top and bottom surfaces of the mounting bracket 100.

[0018] Specifically, by hinged to the inner side of the traditional hood, a mounting bracket 100 is connected, and the sealing strip 200 is fixed to the mounting bracket 100. This allows the mounting bracket 100 to indirectly fix the sealing strip 200 between the hood and the engine compartment. This enables the hood to be unfolded when replacing the sealing strip 200, and then the mounting bracket 100 to be unfolded. This makes it convenient for users to replace the sealing strip 200 on the outside of the hood, eliminating the need to replace the sealing strip 200 at the bottom of the hood in the traditional way, and improving the convenience of replacing the sealing strip 200.

[0019] By designing the middle of the sealing strip 200 as a long strip 210, and designing the top and bottom of the sealing strip 200 as long strips with holes in the middle as strips 220, the sealing strip 210 can easily snap the entire sealing strip 200 into the middle of the mounting bracket 100. The two strips 220 can be installed on both sides of the mounting bracket 100 respectively, so that when the hood is closed on the engine compartment, the two strips 220 can fill the tiny gaps between the hood and the body, which is conducive to achieving a better sealing effect.

[0020] like Figure 3 As shown, in this embodiment, the mounting bracket 100 is shaped like an inverted triangle to fit the edge of the sealing cover, so that after the sealing cover is closed onto the cabin, the mounting bracket 100 can be arranged between the cabin and the sealing plate, and the sealing strip 200 can fill the gap between the cabin and the sealing plate.

[0021] like Figure 2 and Figure 3 As shown, in this embodiment, hinges 120 are installed between both ends of the mounting bracket 100 and the sealing cover, so that the mounting bracket 100 can rotate with the sealing strip 200 to the outside of the sealing plate, making it convenient for the user to check the aging condition of the sealing strip 200 or replace the sealing strip 200 from the outside of the sealing cover.

[0022] like Figure 3 As shown, in this embodiment, the depth of the mounting groove 110 is greater than the thickness of the first adhesive strip 210, so that after the sealing adhesive strip 200 is installed on the mounting bracket 100, the two second adhesive strips 220 can be tensioned and arranged on the outside of the mounting bracket 100 through the first adhesive strip 210, thereby improving the firmness of the installation of the sealing adhesive strip 200 and the mounting bracket 100.

[0023] In this embodiment, when it is necessary to install the sealing strip 200, one end of the notch 240 of the sealing strip 200 is inserted into one end of the mounting groove 110. Then, the sealing strip 200 is moved along the mounting groove 110 of the mounting bracket 100. Finally, the notch 240 of the sealing strip 200 is moved to one end of the limiting strip 130 of the mounting bracket 100 to realize the installation of the sealing strip 200. Conversely, when removing the sealing strip 200, it is only necessary to pull the sealing strip 200 from one end of the mounting groove 110 to pull the sealing strip 200 out of the mounting groove 110.

[0024] like Figure 4As shown, in this embodiment, two limiting strips 130 are fixed on the top and bottom surfaces of one end of the mounting bracket 100. The surface of the limiting strip 130 is an arc-shaped surface, which can fit tightly with the second adhesive strip 220, thereby limiting the position of the second adhesive strip 220 at one end of the mounting bracket 100. Since there is no first adhesive strip 210 at this end that is engaged with the mounting groove 110, the limiting strip 130 can prevent the end of the sealing adhesive strip 200 from being misaligned.

[0025] like Figure 3 and Figure 5 As shown, in this embodiment, a notch 240 is reserved at one end of the sealing strip 200. The notch 240 is snapped into the end of the mounting bracket 100 near the limiting strip 130, so that the sealing strip 200 can still be installed in the area of ​​the mounting bracket 100 without the mounting groove 110, so that the entire outer side of the mounting bracket 100 is covered with the sealing strip 200.

[0026] like Figure 3 As shown, in this embodiment, the first adhesive strip 210 is a long strip with a rectangular cross-section, which is convenient to be snapped into the mounting groove 110. The second adhesive strip 220 has an elliptical hole 230 through the middle. The elliptical hole 230 helps the second adhesive strip 220 to undergo elastic deformation when subjected to pressure, filling the gap between the cover and the cabin.

[0027] In this embodiment, the materials of the first rubber strip 210 and the second rubber strip 220 are EPDM rubber or polyvinyl chloride. The specific material selection is based on existing technology. The sealing rubber strip 200 can be made of materials suitable for composite use conditions as needed. One second rubber strip 220 abuts against the inner edge of the engine compartment, and the other second rubber strip 220 abuts against the inner edge of the sealing cover, so that the second rubber strips 220 on both sides of the mounting bracket 100 seal the gap between the sealing cover and the engine compartment.

[0028] 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.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
