A carbon fiber roof crossbeam assembly

Abstract

This utility model relates to a carbon fiber roof, and more particularly to a crossbeam assembly for a carbon fiber roof, including a frame structure. The main body of the frame structure is a vehicle frame structure. Positioning grooves are arranged in a linear array inside the frame structure, with the positioning grooves having a through-structure on both the upper and lower sides. A reinforcing positioning plate is embedded in the through-slot on the upper side of the positioning groove. This utility model, by using a through-structure for the positioning grooves inside the frame structure, optimizes weight while ensuring basic support function, compared to traditional single solid or simple hollow structures. The reinforcing positioning plate, embedded in the through-slot on the upper side of the positioning groove and with a thickness greater than the wall thickness of the frame structure, directly strengthens the opening area, compensating for the weakening of the overall strength of the frame due to the opening. Combined with the synergistic effect of the positioning sleeve at the bottom of the reinforcing positioning plate and the lower support plate, the shear resistance of this area is significantly improved, effectively preventing excessive tearing under stress and ensuring the stability of the connection between the crossbeam assembly and the vehicle body.

Description

Technical Field

[0001] This utility model relates to a carbon fiber vehicle roof, and more particularly to a crossbeam assembly for a carbon fiber vehicle roof. Background Technology

[0002] As the automotive industry continues to demand higher standards for lightweighting, energy conservation, and environmental performance, the roof beam assemblies made of traditional metal materials (such as steel and aluminum alloys) are gradually revealing problems such as heavy weight, high fuel consumption, poor corrosion resistance, and susceptibility to fatigue deformation after long-term use.

[0003] When applying for this utility model, the applicant, through a search, discovered a Chinese patent disclosing "A Carbon Fiber Roof Crossbeam Assembly," application number "CN202123371163.5." This patent mainly describes a supporting crossbeam connected to the vehicle frame via a connecting mechanism; the connecting mechanism includes a connecting plate; one end of the connecting plate is connected to the vehicle frame, and the other end is connected to the supporting crossbeam. This utility model discloses a carbon fiber roof crossbeam assembly. Through the use of carbon fiber material, the crossbeam assembly of this utility model is relatively lightweight. Furthermore, the connecting mechanism facilitates the connection between the roof crossbeam and adjacent components, thereby simplifying the assembly and connection of the roof crossbeam.

[0004] Existing carbon fiber roof crossbeams are mostly single solid or simple hollow structures. While ensuring structural strength and rigidity, it is difficult to further optimize the weight. Moreover, when the crossbeam assembly is assembled with the frame body, the openings in the crossbeam assembly will affect the overall strength of the frame. When subjected to shear force, it is easy to cause excessive tearing, which will affect the stability of the connection. Summary of the Invention

[0005] The purpose of this invention is to provide a carbon fiber roof crossbeam assembly that reduces weight while ensuring the overall strength of the crossbeam.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a carbon fiber roof crossbeam assembly, including a frame mechanism, the main body of which is a vehicle frame structure, and the interior of the frame mechanism is provided with positioning grooves in a linear array, the positioning grooves being a through structure on both the upper and lower sides, and a reinforcing positioning plate being embedded in the through groove on the upper side of the positioning groove. The thickness of the reinforcing positioning plate is greater than the wall thickness of the skeleton mechanism. A vehicle body connection hole is opened at the center of the interior of the reinforcing positioning plate. A cylindrical positioning sleeve is fixedly connected to the bottom end face of the reinforcing positioning plate. There are two positioning sleeves in total. The two positioning sleeves are fixedly connected to the bottom end face of the reinforcing positioning plate in a linear array. An internal thread is opened on the inner wall of the positioning sleeve. A lower support plate is provided directly below the reinforcing positioning plate. Optionally, a positioning sleeve is fixedly connected to the top surface of the lower support plate. There are two positioning sleeves in total, and the two positioning sleeves are fixedly connected to the top surface of the lower support plate in a linear array. The positioning sleeves are hollow structures.

[0007] Optionally, a connecting bolt passes through the inside of the positioning sleeve from bottom to top. The connecting bolt is screwed into the positioning sleeve and is used to limit the connection between the reinforcing positioning plate and the lower support plate.

[0008] Optionally, there are two skeleton mechanisms arranged in a longitudinal array, and a reinforcing support plate is fixedly connected to the inner side of each skeleton mechanism.

[0009] Optionally, the reinforcing support plate is arranged in an X shape, and the reinforcing support plate is used to support the skeleton mechanism. A bracket support plate is fixedly connected to the inner side of the skeleton mechanism.

[0010] Optionally, the bracket support plate is provided in four places, wherein every two longitudinally adjacent bracket support plates form a group, and the two groups of bracket support plates are fixedly connected to the front and rear sides inside the skeleton mechanism in opposite directions.

[0011] Optionally, the bracket support plate has an L-shaped structure, and buffer pads are fixedly connected to the top of both sets of bracket support plates.

[0012] Optionally, the buffer pad is made of rubber, and a carbon fiber crossbeam is attached to the top of the buffer pad. The carbon fiber crossbeam is a roof crossbeam structure.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model utilizes the lightweight properties of carbon fiber to significantly reduce the overall weight of the crossbeam assembly, thereby reducing fuel consumption and avoiding the poor corrosion resistance of traditional metal materials, thus extending the service life of the crossbeam assembly. Simultaneously, the positioning grooves inside the frame structure employ a through-type structure, which, compared to traditional single solid or simple hollow structures, further optimizes weight while ensuring basic support functionality. The reinforcing positioning plate, embedded in the upper through-slot and thicker than the frame structure wall, directly reinforces the opening area, compensating for the weakening of the frame's overall strength due to the opening. Combined with the synergistic effect of the positioning sleeve at the bottom of the reinforcing positioning plate and the lower support plate, this significantly improves the shear resistance of this area, effectively preventing excessive tearing under stress and ensuring the stability of the connection between the crossbeam assembly and the vehicle body.

[0014] 2. This utility model uses two longitudinally arrayed skeleton mechanisms as the basic framework, providing a stable support foundation for the entire crossbeam assembly. The inner reinforcing support plate, positioning groove, and reinforced positioning plate work together to construct a multi-dimensional reinforced structure, avoiding the problem of insufficient support from a single structure. The body connection hole at the center of the reinforced positioning plate ensures the accuracy and reliability of the connection with the body. The combination of the positioning sleeve and the lower support plate, through the subsequent assembly of connecting components, makes the reinforced positioning plate and the lower support plate form a stable whole, jointly sharing the external force on the skeleton mechanism, further improving the overall structural strength and rigidity of the crossbeam assembly, and completely solving the core problems of the difficulty in balancing weight and strength and the impact of openings on structural stability in the prior art.

[0022] Reference Figure 1-6 The present invention will now describe a carbon fiber roof crossbeam assembly provided in an embodiment of the present invention. The carbon fiber roof crossbeam assembly includes a frame mechanism 1. The main body of the frame mechanism 1 is a vehicle frame structure. The frame mechanism 1 has positioning grooves 1011 arranged in a linear array inside. The positioning grooves 1011 have a through structure on both the upper and lower sides. A reinforcing positioning plate 2 is embedded in the through groove on the upper side of the positioning groove 1011. The thickness of the reinforcing positioning plate 2 is greater than the wall thickness of the frame mechanism 1. A body connection hole 201 is provided at the center of the reinforcing positioning plate 2. Two cylindrical positioning sleeves 2012 are fixedly connected to the bottom surface of the reinforcing positioning plate 2 in a linear array. Internal threads are provided on the inner wall of the positioning sleeves 2012. A lower support plate 2013 is provided directly below the reinforcing positioning plate 2. The main body is a frame structure with vertically aligned positioning grooves 1011 on both the upper and lower sides. In the skeleton mechanism 1, a reinforcing positioning plate 2 with a thickness greater than the wall thickness of the skeleton mechanism 1 is embedded in the upper through groove of the positioning groove 1011. At the same time, two positioning sleeves 2012 with internal threads are fixed at the bottom end of the reinforcing positioning plate 2, and a lower support plate 2013 is set below it. A body connection hole 201 is opened in the center of the reinforcing positioning plate 2. This can achieve connection with the body while using the reinforcing positioning plate 2 to enhance the structural strength of the positioning groove 1011 of the skeleton mechanism 1, avoiding the impact of the hole on the overall strength. The positioning sleeves 2012 provide a foundation for subsequent connection with the lower support plate 2013, taking into account both connection requirements and structural stability. In another embodiment of this utility model, please refer to Figures 2 to 5 A positioning sleeve 2014 is fixedly connected to the top surface of the lower support plate 2013. There are two positioning sleeves 2014, which are fixedly connected to the top surface of the lower support plate 2013 in a straight array. The positioning sleeve 2014 is a hollow structure. By fixing two hollow positioning sleeves 2014 in a straight array to the top of the lower support plate 2013, a passage can be provided for the connecting bolt 2015. This ensures that the connecting bolt 2015 can be accurately aligned when connecting the reinforcing positioning plate 2 and the lower support plate 2013, avoiding installation misalignment, improving the accuracy and stability of the connection between the two, and thus enhancing the structural reliability of the entire beam assembly.

[0023] In another embodiment of this utility model, please refer to Figures 1 to 4 A connecting bolt 2015 passes through the inside of the positioning sleeve 2014 from bottom to top. The connecting bolt 2015 is screwed into the positioning sleeve 2012. The connecting bolt 2015 is used to limit the connection between the reinforcing positioning plate 2 and the lower support plate 2013. By allowing the connecting bolt 2015 to pass through the positioning sleeve 2014 from bottom to top and be screwed into the positioning sleeve 2012, the reinforcing positioning plate 2 and the lower support plate 2013 can be effectively limited, so that the two form a stable overall structure, which together strengthens the positioning groove 1011 of the skeleton mechanism 1, further improves the shear resistance of this part, prevents tearing under stress, and ensures connection stability.

[0024] In another embodiment of this utility model, please refer to Figure 4 Zhihe Figure 5There are two frame mechanisms 1, which are arranged in a longitudinal array. The inner side of each frame mechanism 1 is fixedly connected to a reinforcing support plate 101. By setting two frame mechanisms 1 arranged in a longitudinal array and fixing the reinforcing support plate 101 to their inner side, a double frame support structure can be formed. With the support of the reinforcing support plate 101 on the frame mechanism 1, the overall structural strength and rigidity of the entire beam assembly are greatly improved, its load-bearing capacity is enhanced, and it can better meet the needs of the roof.

[0025] In another embodiment of this utility model, please refer to Figure 1 and Figure 2 The reinforcing support plate 101 is arranged in an X shape and is used to support the skeleton mechanism 1. The inner side of the skeleton mechanism 1 is fixedly connected to the bracket support plate 3. By setting the reinforcing support plate 101 in an X shape, the mechanical advantages of the X-shaped structure can be utilized to distribute the external force on the skeleton mechanism 1 more evenly, further improving the support effect on the skeleton mechanism 1. At the same time, the bracket support plate 3 is fixedly connected to the inner side of the skeleton mechanism 1 to provide a support foundation for the subsequent installation of the carbon fiber crossbeam 3011, so as to achieve stable bearing of the carbon fiber crossbeam 3011. The outer side of the reinforcing positioning plate 2 is fixedly connected to the anti-slip protrusion 2011.

[0026] In another embodiment of this utility model, please refer to Figures 5 to 6 There are four bracket support plates 3 in total. Each pair of longitudinally adjacent bracket support plates 3 forms a group. The two groups of bracket support plates 3 are fixedly connected to the front and rear sides inside the frame mechanism 1 in opposite directions. By fixing the four bracket support plates 3 in opposite directions to the front and rear sides inside the frame mechanism 1 in pairs of longitudinally adjacent groups, symmetrical support can be formed for the carbon fiber crossbeam 3011 from the front and rear sides, ensuring uniform distribution of support force and avoiding deformation or damage to the carbon fiber crossbeam 3011 due to uneven force, thereby improving the stability and service life of the carbon fiber crossbeam 3011 after installation.

[0027] In another embodiment of this utility model, please refer to Figure 2 and Figure 3 The bracket support plate 3 has an L-shaped structure. Both sets of bracket support plates 3 have buffer pads 301 fixedly connected to their top ends. By setting the bracket support plate 3 to an L-shaped structure and fixing the buffer pads 301 to its top end, the L-shaped structure can increase the contact area between the bracket support plate 3 and the frame mechanism 1 and the carbon fiber crossbeam 3011, thereby improving the support stability. The rubber buffer pads 301 can effectively absorb the vibration and impact during vehicle operation, reduce damage to the carbon fiber crossbeam 3011, and reduce noise.

[0028] In another embodiment of this utility model, please refer to Figures 3 to 5The buffer pad 301 is made of rubber, and a carbon fiber crossbeam 3011 is attached to the top of the buffer pad 301. The carbon fiber crossbeam 3011 is a roof crossbeam structure. By attaching the carbon fiber crossbeam 3011 to the top of the buffer pad 301, the carbon fiber crossbeam 3011, as a roof crossbeam structure, can significantly reduce the overall weight of the roof crossbeam assembly by utilizing the lightweight characteristics of carbon fiber material, thus meeting the requirements of automotive lightweighting. At the same time, in conjunction with the buffering effect of the buffer pad 301 and the reinforced support of various components, the overall strength and performance of the crossbeam are ensured while reducing weight.

[0029] In use, firstly, two longitudinally arrayed skeleton mechanisms 1 serve as the basic support structure for the entire crossbeam assembly. The main body of the skeleton mechanism 1 is the frame structure, which can provide a stable frame for the subsequent assembly of various components. Positioning slots 1011 are opened in a linear array inside each skeleton mechanism 1. The positioning slots 1011 are designed to be through-structures on both the upper and lower sides. This structure not only reserves space for the subsequent installation of the reinforcing positioning plate 2, but also avoids the increase in overall weight due to a single solid structure. At the same time, the through-structure facilitates subsequent assembly operations. The reinforcing positioning plate 2 is embedded in the upper through groove of the positioning groove 1011. Since the thickness of the reinforcing positioning plate 2 is greater than the wall thickness of the frame mechanism 1, it can directly reinforce the opening of the positioning groove 1011 of the frame mechanism 1 after being embedded, thus compensating for the impact of the opening on the overall strength of the frame. The body connection hole 201 opened at the center of the reinforcing positioning plate 2 can be used to connect with the body, providing an interface for the assembly of the crossbeam assembly and the body. On the bottom surface of the reinforcing positioning plate 2, two cylindrical positioning sleeves 2012 are fixedly connected in a straight array. The inner wall of the positioning sleeve 2012 is provided with internal threads. This internal thread structure provides the conditions for the subsequent screwing of the connecting bolt 2015. A lower support plate 2013 is set directly below the reinforcing positioning plate 2. On the top surface of the lower support plate 2013, two hollow positioning sleeves 2014 are fixedly connected in a straight array corresponding to the position of the positioning sleeves 2012. The hollow design of the positioning sleeves 2014 provides a channel for the connecting bolt 2015 to pass through, ensuring the accurate alignment of the connecting parts. The connecting bolt 2015 is passed through the positioning sleeve 2014 at the top of the lower support plate 2013 from bottom to top, and the connecting bolt 2015 is screwed into the positioning sleeve 2012 at the bottom of the reinforcing positioning plate 2. Through the limiting effect of the connecting bolt 2015, the reinforcing positioning plate 2 and the lower support plate 2013 form a stable connection. The two together provide double reinforcement to the positioning groove 1011 of the skeleton mechanism 1, further improving the shear resistance of this part and preventing excessive tearing when subjected to force. X-shaped reinforcing support plates 101 are fixedly connected to the inner sides of both skeleton mechanisms 1. The X-shaped structure can evenly distribute the external force on the skeleton mechanism 1 by utilizing mechanical advantages, thereby enhancing the structural stability and support capacity of the skeleton mechanism 1. At the same time, four bracket support plates 3 are fixedly connected to the inner side of the skeleton mechanism 1. Each pair of longitudinally adjacent bracket support plates 3 forms a group. The two groups of bracket support plates 3 are fixedly connected to the front and rear sides inside the skeleton mechanism 1 in opposite directions. The L-shaped bracket support plates 3 can increase the contact area with subsequent components, providing a stable support foundation for the installation of the carbon fiber crossbeam 3011. Rubber buffer pads 301 are fixedly connected to the top of both sets of bracket support plates 3. After the carbon fiber crossbeam 301 is installed, the buffer pads 301 can absorb the vibration and impact during vehicle operation. The carbon fiber crossbeam 3011 is attached to the top of the buffer pads 301. As a roof crossbeam structure, the carbon fiber crossbeam 3011 not only provides roof support but also reduces the overall weight by utilizing the properties of carbon fiber. This completes the assembly and preparation of the entire carbon fiber roof crossbeam assembly. The components work together to achieve the dual functions of lightweight and high strength.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
