Description

Technical Field

[0001] The present invention relates to the field of vehicles, in particular to the field of vehicle sealing. More specifically, the present invention relates to a sealing device for an engine hood and a vehicle using the sealing device. Background Art

[0002] The engine hood of a vehicle is used to protect the engine and surrounding pipeline accessories, including circuits, oil circuits, brake systems, and transmission systems. In order to make the engine hood provide more reliable protection, a sealing device is usually installed on the periphery of the engine frame of the vehicle that accommodates the engine to improve the sealing performance of the engine hood. In addition, such a sealing device can improve the strength and structure of the engine hood, prevent the adverse effects of impact, corrosion, rain, electrical interference, etc. on the engine, thereby protecting the normal operation of the vehicle engine.

[0003] However, the strength of the sealing device currently used in the engine hood is not enough to provide sufficient support for the engine hood, and therefore is not enough to generate sufficient tension on the entire engine hood, thereby causing the vibration problem of the engine hood during driving. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art and to provide a sealing device for an engine hood with higher strength.

[0005] To this end, according to one aspect of the present invention, a sealing device for an engine hood is provided, wherein the sealing device comprises: an elongated and hollow sealing member which is elastically deformable; a mounting member which extends along the longitudinal direction of the sealing member and is fixed to the sealing member; and a reinforcing member which is constructed to include a hollow elongated body and is arranged in the sealing member, wherein only a portion of the outer wall of the reinforcing member abuts against the inner wall of the sealing member, so that a compression space is formed between the reinforcing member and the sealing member.

[0006] According to the above technical concept, the present invention may further include any one or more of the following optional forms.

[0007] In certain optional forms, when the seal is compressed, the outer wall of the reinforcement member abuts against the inner wall of the seal along the compression direction to provide supporting strength.

[0008] In some optional forms, the sealing member and the reinforcing member are both made of rubber.

[0009] In certain optional forms, the material density of the reinforcement member is higher than the material density of the sealing member.

[0010] In certain optional forms, the reinforcement member is configured to be elastically deformable and insertable into or removable from the seal member.

[0011] In certain optional forms, the reinforcement is provided with a plurality of weakened portions spaced apart in the longitudinal direction, and the plurality of weakened portions are recessed inwardly from the outer wall of the reinforcement.

[0012] In some optional forms, the weakened portion is configured as a cutout on an outer wall of the reinforcement member.

[0013] In some optional forms, a gap is formed between the reinforcement member and the mounting member.

[0014] According to yet another aspect of the present invention, a vehicle is provided, wherein the vehicle comprises the above-mentioned sealing device for an engine hood, the mounting member of the sealing device is clamped to the vehicle, and the sealing member is arranged toward the engine hood.

[0015] The present invention improves the sealing member of the sealing device of the engine hood and sets a reinforcing member inside the sealing member, thereby improving the sealing strength of the sealing member, so that the sealing member can generate stronger tension when the engine hood compresses it, thereby reducing the vibration of the engine hood during driving and improving the overall safety performance of the vehicle. In addition, the sealing device of the present invention can better prevent foreign matter such as water and oil from entering the engine and causing pollution to the engine's spark plugs, solenoid valves and other precision components, further extending the service life of the engine.

[0023] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely exemplary of specific ways to implement and use the present invention, and are not intended to limit the scope of the present invention. When describing the structural positions of the various components, such as up, down, top, bottom, etc., the expressions of directions are not absolute, but relative. When the various components are arranged as shown in the figure, these directional expressions are appropriate, but when the positions of the various components in the figure change, these directional expressions also change accordingly.

[0024] In this document, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in this document can be understood according to the specific circumstances.

[0025] In this article, "front" and "rear" are relative to the front and rear directions of the vehicle. In addition, "lateral" refers to the direction of relatively smaller size, also known as the width direction, "longitudinal" refers to the direction of relatively larger size, also known as the length direction, and "vertical direction" refers to the direction generally perpendicular to the ground.

[0026] Generally, a vehicle is provided with a sealing device for a hood, which is clamped to the vehicle to provide sealing strength after the hood is closed. The inventors realize that if the strength of the sealing device is too low, the sealing stability of the hood may be low, so that the hood may vibrate during the driving of the vehicle, and such vibration may be transmitted to the vehicle body, reducing the comfort of the driver and passengers and causing safety hazards to the vehicle.

[0027] Reference Figure 1 , Figure 2 and Figure 3 , Figure 1 is a perspective view of a sealing device for an engine hood according to an embodiment of the present invention, Figure 2 yes Figure 1 A partial enlarged view of the sealing device, and Figure 3 yes Figure 2 Front view of the sealing device.

[0028] A sealing device 100 for an engine hood according to an embodiment of the present invention includes an elongated and hollow sealing member 110 having an elastically deformable portion 111 and a mounting member 120 for fixing the sealing device 100 to a vehicle. The sealing member 110 has a resiliently deformable portion 111 , and the mounting member 120 extends along a longitudinal direction D1 of the sealing member 110 and is fixed to the sealing member 110 .

[0029] like Figure 2 and Figure 3 As shown, the mounting member 120 may have a substantially U-shaped cross section, in which the U-shaped cross section is Figures 1 to 3 As shown in the orientation, the mounting member 120 may be provided with a top wall 123 and a bottom wall 124 which are parallel to and spaced apart from each other along the vertical direction D2, and a side wall 125 extending between the top wall 123 and the bottom wall 124, and an installation space for clamping the sealing device 100 to the vehicle is formed between the top wall 123, the bottom wall 124 and the side wall 125 of the mounting member 120. In the present embodiment, the sealing member 110 has a substantially C-shaped cross section, and the bottom of the sealing member 110 is attached to the top wall 123 of the mounting member 120, that is, the hollow sealing member 110 is surrounded by its elastically deformable portion 111 and the top wall 123 of the mounting member 120. In this way, the connection between the sealing member 110 and the mounting member 120 is simplified, so that the sealing member 110 can be made into a one-piece with the mounting member 120, further reducing the installation time of the sealing device 100 and improving production efficiency.

[0030] In the illustrated embodiment, the mounting member 120 may also be provided with a metal core 121 inside. Such metal core 121 may allow the mounting member 120 to be bent in a controllable manner so that the mounting member 120 is clamped to the vehicle in a form-fitting manner. It is understood that the mounting method of the mounting member 120 is not limited thereto, for example, the mounting member 120 may also be mounted on a metal support member (not shown) to be fitted to the vehicle.

[0031] Continue to refer to Figure 2 The inner surface of the top wall 123 of the mounting member 120 is provided with a lip 122 extending downward from the top wall 123 and toward the side wall 125 of the mounting member, and the lip 122 is conducive to fixing the mounting member 120 to the vehicle. It can be understood that the number and arrangement of the lips 122 vary depending on different needs and are not limited to those shown in the figure.

[0032] The inventors have discovered that when the engine hood acts on the seal 110 of the sealing device 100 , the seal 110 , due to its relatively low strength, causes the engine hood to vibrate during vehicle driving, and such vibration reduces the comfort and safety performance of the vehicle.

[0033] The present invention provides a reinforcing member 130 in the seal 110 to improve the strength of the seal 110 while avoiding the above problems. The reinforcing member 130 according to the exemplary embodiment of the present invention is configured to include a hollow elongated body 132 and is arranged in the seal 110, such as Figure 3 As shown, only a portion of the outer wall 133 of the reinforcement 130 abuts against the inner wall 112 of the seal 110 , so that a compression space 140 for the engine hood to act on is formed between the top of the reinforcement 130 and the inner surface of the seal 110 .

[0034] In this way, the present invention improves the sealing strength of the seal 110 by disposing the reinforcement member 130 in the seal 110 without changing the outer contour of the seal 110, thereby reducing the manufacturing cost.

[0035] Reference Figure 6 , Figure 6 FIG. 1 is a schematic diagram of a sealing device 100 according to an embodiment of the present invention when it is installed in a vehicle.

[0036] Figure 6 It is shown that, in the state where the seal 110 of the sealing device 100 is not compressed, the engine hood 200 acts on the top of the seal 110, and at this time, the seal 110 is not deformed. When the engine hood 200 compresses the seal 110 downward, the elastically deformable portion 111 of the seal 110 is elastically deformed, so that the inner wall 112 of the elastically deformable portion 111 abuts against the outer wall 133 of the reinforcement 130 along the compression direction D3 (the top of the reinforcement 130 when the compression direction D3 is substantially the same as the vertical direction D2). In this way, the reinforcement 130 can provide support strength when the seal 110 is compressed.

[0037] In some embodiments, the sealing member 110 and the reinforcing member 130 may both be made of rubber. Rubber has high elasticity, a cushioning and shock-absorbing effect, and electrical insulation performance, and can also maintain good performance when the temperature rises, thereby increasing the service life of the sealing device 100 and improving the safety performance of the vehicle. In addition, the material density of the reinforcing member 130 may be higher than the material density of the sealing member 110. For example, the reinforcing member 130 may be polyethylene, and the sealing member 110 may be silicone rubber. In this way, the reinforcing member 130 is helpful to provide a higher support strength, thereby improving the sealing performance of the sealing member 110.

[0038] Reference Figure 4 , Figure 4 is a perspective view of a reinforcement member 130 according to an embodiment of the present invention.

[0039] In some embodiments, the reinforcement member 130 can be elastically deformed and inserted into or removed from the seal 110. In this way, the reinforcement member 130 can be made independently of the seal 110, so that the reinforcement member 130 can be processed separately. For example, reinforcement members 130 with different material densities can be arranged in the seal 110 according to different vehicle requirements without changing the structure of the seal 110, thereby further reducing manufacturing costs.

[0040] In addition, in some embodiments, a space may be formed between the reinforcement member 130 and the mounting member 120. Figure 3 Thus, a portion of the outer wall 133 of the reinforcement member 130 is formed as shown in FIG. Figure 3 The method shown in FIG. 1 only contacts the inner surfaces on both sides of the sealing member 110 , thereby facilitating installation, removal, replacement and maintenance of the reinforcement member 130 , reducing the installation time of the reinforcement member, and thus improving production efficiency.

[0041] Reference Figure 5 , Figure 5 yes Figure 4 A partial enlarged view of .

[0042] In some embodiments, the reinforcement member 130 may be provided with a plurality of weakened portions 131, and the plurality of weakened portions 131 are spaced apart along the longitudinal direction of the reinforcement member 130, wherein the longitudinal direction of the reinforcement member 130 is substantially consistent with the longitudinal direction D1 of the sealing member 110. Specifically, the plurality of weakened portions 131 are spaced apart at the same interval along the longitudinal direction of the reinforcement member 130. Figure 5 As shown in FIG. 1 , the weakened portion 131 in this embodiment is arranged to be recessed inwardly from the outer wall 133 of the reinforcement member 130 along the radial direction of the reinforcement member 130. In this way, the present invention reduces the difficulty in closing the engine hood 200 due to the excessive strength of the reinforcement member 130 by partially weakening the reinforcement member 130. Figure 5 In the illustrated embodiment, the weakened portion 131 is configured as a cutout on the outer wall 133 of the reinforcing member 130. It is understood that the number and shape of the weakened portion 131 may vary depending on different needs and are not limited to those shown in the drawings.

[0043] In the illustrated embodiment, the reinforcement 130 has a circular cross-section. It should be noted that the cross-sectional shape of the reinforcement 130 is not limited thereto. For example, in different embodiments, the reinforcement 130 can be constructed as a hollow tubular member with an elliptical or polygonal cross-section, as long as it is suitable for providing supporting strength.

[0044] It should be understood that the embodiments shown in the figures only illustrate optional shapes, sizes and arrangements of the sealing device according to the present invention. However, they are only exemplary embodiments and are not limitations of the present invention. Other shapes, sizes and arrangements may also be adopted without departing from the spirit and scope of the present invention.

[0045] The technical content and technical features of the present invention have been disclosed above. However, it can be understood that under the creative ideas of the present invention, those skilled in the art can make various changes and improvements to the above disclosed concepts, but they all belong to the protection scope of the present invention. The description of the above embodiments is illustrative rather than restrictive, and the protection scope of the present invention is determined by the claims.
