The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] First Embodiment

[0020] Please see Figures 1-3 , Figure 1 This is a structural diagram of the front and rear lips of a car made of carbon fiber composite material, according to this utility model. Figure 2 This is a cross-sectional schematic diagram of the front and rear lips of a car made of carbon fiber composite material according to this utility model. Figure 3 This is a partial schematic diagram of the front and rear lips of a car made of carbon fiber composite material according to this utility model.

[0021] This utility model provides a carbon fiber composite material for front and rear automotive lips: including a carbon fiber lip plate 101 and a connecting assembly 102. The connecting assembly 102 includes a positioning groove 103, a positioning block 104, an elastic sheet 105, a slot 106, a limiting member 107, epoxy resin 108, carbon fiber cloth 109, a limiting block 110, a locking bolt 111, an epoxy primer 112, an anti-ultraviolet coating 113, a ceramic varnish 114, and a damper 115. This solution solves the problem that existing devices, which use bolts to fix the lip plate during installation, experience vibration during movement over long-term use, leading to loose bolts, gaps at the connection, and increased wind noise.

[0022] In this embodiment, the positioning block 104 is fixedly connected to the carbon fiber lip plate 101 and located on one side of the carbon fiber lip plate 101. The positioning groove 103 is slidably connected to the positioning block 104 and located inside the positioning groove 103. The elastic sheet 105 is fixedly connected to the carbon fiber lip plate 101 and located at one end of the carbon fiber lip plate 101. The slot 106 is slidably connected to the elastic sheet 105 and located outside the elastic sheet 105. The limiting member 107 is connected to the slot 106 and located on one side of the slot 106. The positioning block 104 and the carbon fiber lip plate 101 are integrally molded and have the same strength as the carbon fiber lip plate 101. The positioning groove 103 is installed on the frame in an integral molding manner, which can improve the overall strength of the frame. The positioning block 104 is inserted into the positioning groove 103 for clearance fit installation, improving the overall connection between the lip plate and the frame. The slot 106 is also integrally molded and set in the frame. The elastic piece 105 is made of elastic high-strength alloy. One side is set as a triangular block that slides into the slot 106. After the triangular block is inserted into the slot 106, it contacts the outer edge of the slot 106, so that the elastic piece 105 cannot be removed from the slot 106 without external force. The position of the elastic piece 105 is restricted by the limiting member 107 to prevent the elastic piece 105 from deforming under the influence of external force. This solves the problem that in the existing device, the lip plate is fixed with bolts during installation. During long-term use, the device shakes during movement, causing the bolts to loosen, resulting in gaps at the connection and affecting wind noise.

[0023] The carbon fiber lip plate 101 includes epoxy resin 108 and carbon fiber cloth 109. The epoxy resin 108 is connected to the positioning block 104 and the elastic sheet 105, and is located on one side of the positioning block 104. The carbon fiber cloth 109 is fixedly connected to the epoxy resin 108 and is located on one side of the epoxy resin 108. The carbon fiber cloth 109 is made of 3k and is woven using a unidirectional and bidirectional weaving process. The carbon fiber cloth 109 and the epoxy resin 108 are composite molded and cured in a thermostatic press. During the molding process, the elastic sheet 105 is wrapped by the epoxy resin 108 to improve the connection between the two. At the same time, the strength of the elastic sheet 105 is improved by the epoxy resin 108 and the carbon fiber cloth 109.

[0024] Secondly, the limiting member 107 includes a limiting block 110 and a locking bolt 111. The limiting block 110 is slidably connected to the slot 106 and is located on one side of the slot 106. The locking bolt 111 is threadedly connected to the slot 106 and is located on one side of the slot 106. After the elastic piece 105 is slidably inserted into the slot 106, the limiting block 110 is slidably inserted into the slot 106 to compress and limit the elastic piece 105. The locking bolt 111 threadedly connects the limiting block 110 to the slot 106 to prevent the limiting block 110 from sliding.

[0025] Furthermore, the connecting component 102 also includes an epoxy primer 112, an anti-UV coating 113, and a ceramic varnish 114. The epoxy primer 112 covers the surface of the carbon fiber cloth 109, the anti-UV coating 113 covers the surface of the epoxy primer 112, and the ceramic varnish 114 covers the surface of the anti-UV coating 113. The epoxy primer 112 enhances the adhesion of the carbon fiber lip plate 101 to other topcoats. The anti-UV coating absorbs ultraviolet rays to improve the service life of the device. The ceramic varnish 114 has a hardness of 3H, and its scratch resistance is twice that of ordinary varnish. It also has a hydrophobic self-cleaning function with a water contact angle ≥110°, allowing rainwater to automatically wash away surface stains.

[0026] Finally, the connection assembly 102 also includes a damper 115, which is connected to the carbon fiber lip plate 101 and located on one side of the carbon fiber lip plate 101. One end of the damper 115 is connected to the carbon fiber lip plate 101 and the other end is connected to the frame, thereby reducing the force of the frame on the carbon fiber lip plate 101 during use and improving the service life of the device.

[0027] In the use of the carbon fiber composite material automotive front and rear lips of this utility model, the positioning block 104 is integrally formed with the carbon fiber lip plate 101, possessing the same strength as the carbon fiber lip plate 101. The positioning groove 103 is integrally formed and installed on the vehicle frame, which can improve the overall strength of the vehicle frame. The positioning block 104 is inserted into the positioning groove 103 for clearance fit installation, improving the overall connection between the lip plate and the vehicle frame. The slot 106 is also integrally formed and set in the vehicle frame. The elastic piece 105 is made of elastic high-strength alloy. One side is set as a triangular block that slides into the slot 106. After the triangular block is inserted into the slot 106, it contacts the outer edge of the slot 106, so that the elastic piece 105 cannot be removed from the slot 106 without external force. The position of the elastic piece 105 is restricted by the limiting member 107 to prevent the elastic piece 105 from deforming under the influence of external force. This solves the problem that in the existing device, the lip plate is fixed with bolts during installation. During long-term use, the device shakes during movement, causing the bolts to loosen, resulting in gaps at the connection and affecting wind noise.

[0028] The above-disclosed embodiments are merely preferred embodiments of the carbon fiber composite automotive front and rear lips of this utility model, and should not be construed as limiting the scope of this utility model. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this utility model still fall within the scope of this utility model.
