Description

Technical Field

[0001] This utility model relates to the field of roll cage technology, and in particular to a bonded structure of carbon fiber hollow tube and metal joint and a roll cage. Background Technology

[0002] As a core component of a vehicle's safety protection system, the roll cage consists of a carbon fiber hollow tube and metal joints. The carbon fiber hollow tube reduces overall weight while maintaining structural stability, and it is connected to the metal joints to facilitate assembly with other components. In existing technology, metal joints have a main body and a plug-in part. The plug-in part has a recessed outer periphery forming a glue-receiving groove. During assembly, glue is first applied to the glue-receiving groove, and then the plug-in part is inserted into the insertion hole of the carbon fiber hollow tube. The two are fixedly connected by the glue curing. However, this traditional adhesive structure and assembly method has obvious defects in practical applications, making it difficult to ensure the uniform distribution of glue on the adhesive surface: On the one hand, the glue is pre-applied to the glue-receiving groove. During the insertion of the plug-in part into the carbon fiber hollow tube, the glue is easily shifted, accumulated, or lost due to the squeezing action generated by the insertion action. This results in excessive glue in some adhesive areas and insufficient glue or even empty glue in some areas (especially the end of the glue-receiving groove far from the main body or the edge where the plug-in part mates with the insertion hole). On the other hand, since the glue-receiving groove is in a closed or semi-closed state, the pre-applied glue is difficult to fully fill all corners of the glue-receiving groove, and the filling status of the glue cannot be observed, further aggravating the problem of uneven glue distribution. Therefore, it is necessary to design a new technical solution to solve the above problems. Utility Model Content

[0003] In view of the above, this utility model addresses the deficiencies of the existing technology and its main purpose is to provide a bonding structure and anti-roll cage for a carbon fiber hollow tube and a metal joint. The main body has an injection hole that connects to the glue-containing groove, and the outer wall of the carbon fiber hollow tube has an overflow hole that connects to the glue-containing groove at the end opposite to the main body. When injecting glue into the glue-containing groove, glue is injected through the injection hole using a glue gun. When glue overflows from the overflow hole, it indicates that the glue-containing groove is full. The amount of glue can be observed from the overflow hole, ensuring that the glue in the glue-containing groove is evenly distributed and sufficient, thereby improving the bonding strength.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A bonding structure for a carbon fiber hollow tube and a metal connector includes a carbon fiber hollow tube and a metal connector. The carbon fiber hollow tube is provided with an insertion hole. The metal connector is provided with a main body and a plug-in part connected to the main body. The outer periphery of the plug-in part is recessed to form an adhesive groove. The adhesive groove is filled with adhesive that can bond the carbon fiber hollow tube and the plug-in part. The metal connector is inserted into the end of the carbon fiber hollow tube through the cooperation of the plug-in part and the insertion hole. The main body has an injection hole that connects to the glue reservoir, and the outer wall of the carbon fiber hollow tube has an overflow hole that connects to the glue reservoir at the end opposite to the glue reservoir. The glue is filled into the glue reservoir from the injection hole.

[0005] As a preferred embodiment, the outer wall surface of the insertion part is recessed at the end of the adhesive groove away from the main body to form an adhesive-blocking groove, and a first baffle is formed between the adhesive-blocking groove and the adhesive groove.

[0006] As a preferred embodiment, the depth of the adhesive blocking groove is greater than the depth of the adhesive receiving groove.

[0007] As a preferred embodiment, the top of the first baffle wall is at a right angle on the side closest to the adhesive reservoir, and the top of the first baffle wall is arc-shaped on the side furthest from the adhesive reservoir.

[0008] As a preferred embodiment, the first baffle portion is exposed above the overflow hole.

[0009] As a preferred embodiment, both the adhesive-blocking groove and the adhesive-receiving groove are arranged in a ring around the outer periphery of the insertion part.

[0010] As a preferred embodiment, a second baffle is provided between the adhesive tank and the main body, and the second baffle is located in the carbon fiber hollow tube.

[0011] As a preferred embodiment, the end of the carbon fiber hollow tube is provided with a first guide surface corresponding to the second baffle, and correspondingly, the end of the insertion part away from the main body is provided with a second guide surface that matches the first guide surface.

[0012] As a preferred embodiment, the plug-in portion is in the shape of a hollow tube, and the main body portion has a through hole that communicates with the plug-in portion.

[0013] A roll cage includes a bonded structure of a carbon fiber hollow tube and a metal joint.

[0014] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution: The main feature is that an injection hole connected to the glue tank is provided in the main body, and an overflow hole connected to the glue tank is provided on the outer wall of the carbon fiber hollow tube at the end of the glue tank away from the main body. When injecting glue into the glue tank, glue is injected through the injection hole using a glue gun. When glue overflows from the overflow hole, it indicates that the glue tank is full. The amount of glue can be observed from the overflow hole, which ensures that the glue in the glue tank is evenly distributed and sufficient, thereby improving the bonding strength.

Detailed Implementation

[0018] First, it should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] Please refer to Figures 1 to 5As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a carbon fiber hollow tube 10 and a metal connector 20.

[0020] The carbon fiber hollow tube 10 is provided with an insertion hole 101. The metal connector 20 is provided with a main body 21 and a plug-in part 22 connected to the main body 21. The outer periphery of the plug-in part 22 is recessed to form a glue-containing groove 201. The glue-containing groove 201 is filled with glue 30 that can bond the carbon fiber hollow tube 10 and the plug-in part 22. The metal connector 20 is inserted into the end of the carbon fiber hollow tube 10 through the cooperation of the plug-in part 22 and the insertion hole 101. The main body 21 is provided with a glue injection hole 202 communicating with the glue-containing groove 201. The outer wall of the carbon fiber hollow tube 10 is provided with an overflow hole 102 communicating with the glue-containing groove 201 at the end of the glue-containing groove 201 away from the main body 21. The glue fills the glue-containing groove 201 from the glue injection hole 202.

[0021] First, insert the connector 22 into the carbon fiber hollow tube 10 through the insertion hole 101. Then, use a glue gun to inject glue into the glue container 201 through the glue injection hole 202. When glue overflows from the overflow hole 102, it indicates that the glue container 201 has been filled, and the glue injection operation is completed. Finally, the carbon fiber hollow tube 10 and the metal connector 20 are fixedly connected by curing.

[0022] See Figure 2 , 4 and Figure 5 As shown, the outer wall surface of the insertion part 22 is recessed on the side away from the main body part 21 of the glue-containing groove 201 to form a glue-blocking groove 203. A first baffle 23 is formed between the glue-blocking groove 203 and the glue-containing groove 201. The glue-blocking groove 203 can prevent some of the glue overflowing from the glue-containing groove 201 from flowing into the carbon fiber hollow tube 10. Preferably, the depth of the adhesive blocking groove 203 is greater than the depth of the adhesive receiving groove 201, making it easier for the adhesive overflowing from the adhesive receiving groove 201 to flow into the adhesive blocking groove 203; the top of the first baffle 23 is at a right angle on the side near the adhesive receiving groove 201, and at an arc shape on the side away from the adhesive receiving groove 201. The right angle design makes it more difficult for the adhesive to overflow from the adhesive receiving groove 201, and the arc shape design makes it easier for the adhesive overflowing from the adhesive receiving groove 201 to flow into the adhesive blocking groove 203; the first baffle 23 is partially exposed in the overflow hole 102. Under this structure, due to the obstruction of the first baffle 23, the adhesive in the adhesive receiving groove 201 can flow directly out from the overflow hole 102 after it is filled, making it less likely for the adhesive receiving groove 201 to overflow into the adhesive blocking groove 203; In this embodiment, both the adhesive-blocking groove 203 and the adhesive-containing groove 201 are arranged in a ring around the outer periphery of the insertion portion 22.

[0023] See Figure 3and Figure 4 As shown, a second baffle 24 is provided between the glue-containing tank 201 and the main body 21. The second baffle 24 is located in the carbon fiber hollow tube 10. The second baffle 24 can prevent glue from easily flowing from the glue-containing tank 201 to the end of the carbon fiber hollow tube 10. Preferably, the end of the carbon fiber hollow tube 10 is provided with a first guide surface 103 corresponding to the second baffle 24. The first guide surface 103 provides a space for the glue to overflow from the second baffle 24 and facilitates the insertion of the plug part 22 into the insertion hole 101. Correspondingly, the end of the plug part 22 away from the main body 21 is provided with a second guide surface 204 that matches the first guide surface 103. The second guide surface 204, in conjunction with the first guide surface 103, makes it easier for the plug part 22 to be inserted into the carbon fiber hollow tube 10. The plug part 22 is hollow tube shaped. The main body 21 has a through hole 205 that connects to the inside of the plug part 22. The through hole 205 can play a role in venting, making it easier for the plug part 22 to be inserted into the carbon fiber hollow tube 10.

[0024] A roll cage includes a roll cage body and a metal joint 20 glued to the roll cage body. The roll cage body has a carbon fiber hollow tube 10 glued to the metal joint 20.

[0025] The key design feature of this utility model is: The main feature is that an injection hole connected to the glue tank is provided in the main body, and an overflow hole connected to the glue tank is provided on the outer wall of the carbon fiber hollow tube at the end of the glue tank away from the main body. When injecting glue into the glue tank, glue is injected through the injection hole using a glue gun. When glue overflows from the overflow hole, it indicates that the glue tank is full. The amount of glue can be observed from the overflow hole, which ensures that the glue in the glue tank is evenly distributed and sufficient, thereby improving the bonding strength.

[0026] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
