Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of spoilers, and particularly relates to a spoiler with high bonding strength. Background Art
[0002] In the technical field of automotive parts, as an important aerodynamic component, the spoiler is widely used to improve the driving stability and fuel economy of vehicles. The traditional spoiler is mainly fixedly connected to the vehicle tailgate through bolts. This method not only requires drilling holes in the tailgate, increasing the structural complexity of the tailgate, but also affects the assembly efficiency and the overall aesthetics of the tailgate. In addition, the bolt connection may cause a decrease in connection strength due to loosening or corrosion during long-term use, thereby affecting the stability and safety of the spoiler.
[0003] In order to overcome the above defects, spoilers connected by bonding methods have gradually emerged in the market. However, the existing bonded spoilers still have deficiencies in bonding strength and connection stability. Especially under high-speed driving and adverse weather conditions, they are prone to falling off or loosening.
[0004] Therefore, it is very necessary to invent a spoiler with high bonding strength. Summary of the Utility Model
[0005] In order to solve the above technical problems, the utility model provides a spoiler with high bonding strength, which includes a spoiler main body, a bonding connection area and a positioning pin. The bonding connection area is arranged on the inner wall surface of the spoiler main body, and the positioning pin is integrally arranged. The positioning pin is located on one side of the buckle structure for fixedly installing the spoiler main body.
[0006] The bonding connection area includes a main bonding channel, a sub-channel, a biting groove and a biting body. The main bonding channel and the sub-channel are connected to each other. The main bonding channel and the sub-channel are arranged on the inner wall surface of the spoiler main body. A plurality of the biting grooves are arranged at the bottom of the main bonding channel, and the biting body is arranged on the groove wall of the main bonding channel.
[0007] Preferably, the main bonding channel is arranged on the surface of the inner side of the edge of the spoiler main body. The main bonding channel is an unclosed channel. The sub-channel is a branch channel of the main bonding channel, and the sub-channels are evenly arranged on the main bonding channel.
[0008] Preferably, the part of the vehicle where the spoiler main body is installed is provided with a serrated protrusion matching the biting groove and a wave protrusion matching the biting body. The biting groove is serrated; the biting body is a wave-shaped protrusion structure.
[0009] Compared with the prior art, the utility model has the following beneficial effects:
[0010] The utility model significantly enhances the bonding strength and overall performance between the spoiler and the installation part. Specifically, the design of the serrated protrusions and the wave-engaging protrusions not only greatly increases the contact area and friction between the bonding surfaces, enabling the adhesive to penetrate more deeply and adhere firmly to the material surface, thus significantly improving the bonding strength. At the same time, the non-closed bonding connection area combined with the ingenious arrangement of the concave-convex structure constructs a complex mechanical locking system after the adhesive cures, effectively enhancing the connection stability between the spoiler and the installation part, making it more difficult to be peeled off by external forces, and greatly improving the durability and safety of the overall structure. In addition, the design of the wave-engaging protrusions also optimizes the stress distribution in the bonding area, effectively dispersing and reducing the stress concentration phenomenon, prolonging the bonding life, and reducing the failure risk caused by excessive stress. Finally, the design of the recessed bonding connection area forms an excellent sealing effect after filling with the adhesive, effectively blocking the intrusion of impurities such as moisture and dust, providing an additional protection barrier for the adhesive and the bonding surface, and further consolidating the stability and durability of the connection.

In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0018] As shown in the attached Figure 1 to the attached Figure 3 figures:
[0019] A spoiler with high adhesion strength provided by the present invention includes a spoiler main body 1, an adhesive connection area 2, and a positioning pin 3. The inner wall surface of the spoiler main body 1 is provided with the adhesive connection area 2, and the positioning pin 3 is integrally provided. The positioning pin 3 is located on one side of the buckle structure fixedly installed on the spoiler main body 1.
[0020] The adhesive connection area 2 includes an adhesive main channel 21, a sub-channel 22, a biting groove 23, and a biting body 24. The adhesive main channel 21 and the sub-channel 22 are connected to each other. The adhesive main channel 21 and the sub-channel 22 are provided on the inner wall surface of the spoiler main body 1. A plurality of the biting grooves 23 are provided at the bottom of the adhesive main channel 21, and the biting body 24 is provided on the wall of the adhesive main channel 21.
[0021] Specifically, the main bonding channel 21 is arranged on the surface inside the edge of the spoiler body 1. This design cleverly utilizes the space inside the edge to ensure that the adhesive can be fully and evenly coated on the key area. The main bonding channel 21 is designed as an open channel, and this open design helps to form a stronger mechanical locking effect during the curing process of the adhesive, increasing the stability of the connection. To enhance the comprehensiveness and reliability of the bonding, the secondary channel 22 is set as a branch channel of the main bonding channel 21 and is evenly distributed on the main bonding channel 21. The introduction of the secondary channel 22 not only increases the bonding area but also enables the adhesive to penetrate more deeply into the tiny gaps between the spoiler body 1 and the installation site, thereby further enhancing the bonding strength.
[0022] Specifically, in order to match the bonding connection area 2 on the spoiler body 1, the installation site of the automotive spoiler body 1 has also been correspondingly optimized in design. Specifically, serrated protrusions matching the engaging groove 23 and wavy protrusions matching the engaging body 24 are provided on the installation site.
[0023] The engaging groove 23 is designed to be serrated. This shape not only increases the contact area between the bonding surfaces but also provides additional friction through its unique geometric structure, helping to prevent the spoiler from loosening due to vibration or external forces during driving. At the same time, the engaging body 24 is presented in a wavy protrusion structure. This design not only forms a good complementary relationship with the engaging groove 23 but also can form a more complex mechanical locking structure after the adhesive cures, further enhancing the stability and durability of the connection.
[0024] Any technical solution using the technical solution of the present utility model, or a similar technical solution designed by those skilled in the art inspired by the technical solution of the present utility model and achieving the above technical effects, shall fall within the protection scope of the present utility model.
