Detailed Implementation

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] The following is for reference. Figures 1-9 The present invention describes a ceiling-mounted screen mounting beam 100, a top cover structure 200, and a vehicle for use according to an embodiment of the present invention.

[0022] According to an embodiment of the present invention, a ceiling-mounted screen mounting beam 100 for a vehicle is provided. The vehicle includes a roof structure 200, which includes a first side beam 201 and a second side beam 202. The first side beam 201 and the second side beam 202 are arranged at intervals along the width direction of the vehicle. The ceiling-mounted screen mounting beam 100 includes: The main body of the crossbeam 10 is used to fix the connection between the first side beam 201 and the second side beam 202. Mounting bracket 20, at least a portion of which is located below the crossbeam body 10 and extends along the length of the crossbeam body 10, is fixed to the crossbeam body 10, and is used to mount the vehicle's ceiling screen. Both the crossbeam body 10 and the mounting bracket 20 are constructed as a single molded part.

[0023] The vehicle includes a roof structure 200, which includes a first side beam 201 and a second side beam 202. The first side beam 201 and the second side beam 202 are arranged at intervals along the width direction of the vehicle. The roof structure 200 also includes a roof. A crossbeam body 10 is used to fix the first side beam 201 and the second side beam 202 between them. The upper end wall of the crossbeam body 10 is fixedly connected to the roof. In some embodiments of this utility model, the crossbeam body 10 and the roof can be fixedly connected by adhesive or by snap-fit. However, this utility model is not limited to these methods. The crossbeam body 10 and the roof can be fixedly connected by other methods, as long as the upper end wall of the crossbeam body 10 is fixedly connected to the roof. As a specific embodiment of this utility model, the crossbeam body 10 and the top cover are bonded together by vibration damping adhesive. Vibration damping adhesive is usually a high-damping elastic adhesive, such as silicone, polyurethane or specific acrylic adhesive. The vibration damping adhesive itself is flexible and can effectively absorb and attenuate the vibration energy between the crossbeam body 10 and the top cover, which is beneficial for noise reduction and structural fatigue reduction, thereby improving the NVH performance of the whole vehicle.

[0024] The main body 10 of the crossbeam is used to fix the first side beam 201 and the second side beam 202. In some embodiments of this utility model, the main body 10 of the crossbeam can be fixedly connected to the first side beam 201 and the second side beam 202 by welding, or the main body 10 of the crossbeam can be fixedly connected to the first side beam 201 and the second side beam 202 by bolts. However, this utility model is not limited to these methods. The main body 10 of the crossbeam can also be fixedly connected to the first side beam 201 and the second side beam 202 by other methods, as long as the main body 10 of the crossbeam is used to fix the connection between the first side beam 201 and the second side beam 202. As a specific embodiment of this utility model, the main body 10 of the crossbeam can be fixedly connected to the first side beam 201 and the second side beam 202 by welding. Welded connections have good strength and rigidity, simple process, high production efficiency, and lighter structure, which is beneficial to the lightweight design of vehicles. The main body 10 of the crossbeam is used to fix the connection between the first side beam 201 and the second side beam 202, and can correspond to the position of the ceiling screen, so as to facilitate the installation of the ceiling screen on the ceiling screen mounting crossbeam 100.

[0025] At least a portion of the mounting bracket 20 is located below the crossbeam body 10, and the mounting bracket 20 extends along the length of the crossbeam body 10 so that the mounting bracket 20 is correspondingly arranged with the crossbeam body 10. The mounting bracket 20 is fixed to the crossbeam body 10. In some embodiments of this utility model, the mounting bracket 20 and the crossbeam body 10 can be fixedly connected by welding, or the mounting bracket 20 and the crossbeam body 10 can be fixedly connected by bolts. However, this utility model is not limited to these methods, and the mounting bracket 20 and the crossbeam body 10 can also be fixedly connected by other methods. As a specific embodiment of this utility model, the mounting bracket 20 and the crossbeam body 10 are fixedly connected by argon arc welding. Argon arc welding has good welding quality and beautiful weld seam, which can save the grinding step, reduce the manufacturing time of the ceiling screen mounting crossbeam 100, and the welding process of argon arc welding is safe and stable, with a low probability of spatter, and is also suitable for all-round welding, which helps to reduce the risk of injury to welders.

[0026] The mounting bracket 20 is used to install the ceiling screen of the vehicle. In some embodiments of this utility model, the mounting bracket 20 and the ceiling screen can be fixedly connected by bolts, or the mounting bracket 20 and the ceiling screen can be fixedly connected by welding. However, this utility model is not limited to this. The mounting bracket 20 and the ceiling screen can also be fixedly connected by other means, as long as the mounting bracket 20 is used to install the ceiling screen of the vehicle.

[0027] Both the main body 10 of the crossbeam and the mounting bracket 20 are constructed as a single molded part. Specifically, the main body 10 of the crossbeam can be extruded from an aluminum profile. Extrusion molding is a process in which heated aluminum billet is forcibly extruded through a mold to obtain a specific cross-sectional shape. It can achieve the maximum bending and torsional stiffness with the least amount of material. Compared with the traditional sheet metal stamping and forming of the ceiling screen mounting structure, it can reduce the mold cost. The extrusion process makes the metal grain flow direction consistent with the profile direction, which improves the longitudinal strength and toughness of the main body 10 of the crossbeam. This allows the main body 10 of the crossbeam to better participate in the transmission and dispersion of collision force, improves the support stability of the main body 10 of the crossbeam to the top cover structure 200, and also improves the bending and torsional stiffness of the ceiling screen mounting crossbeam 100, which in turn helps to improve the NVH performance of the vehicle.

[0028] The mounting bracket 20 can be formed by bending aluminum profiles. Bending is a process of stamping and bending aluminum sheets to obtain the required three-dimensional shape. Bending processes typically use general-purpose molds, eliminating the need to develop expensive special molds for each new design. This results in a short production cycle, making it suitable for small-batch production of vehicles and helping to reduce vehicle production costs. The use of the extruded aluminum profile beam body 10 and the bent aluminum profile mounting bracket 20 in conjunction can balance the structural performance, cost, and development efficiency of the ceiling screen mounting beam 100, thereby reducing manufacturing costs and development cycles while ensuring strength.

[0029] According to the present invention, the ceiling-mounted screen mounting beam 100 for vehicles has at least a portion of the mounting bracket 20 located below the main body 10 of the beam, and the mounting bracket 20 extends along the length direction of the main body 10 of the beam. The mounting bracket 20 is fixed to the main body 10 of the beam and is used to mount the ceiling-mounted screen of the vehicle. The main body 10 of the beam and the mounting bracket 20 are both constructed as an integral molded part. The main body 10 of the beam is formed by extrusion of aluminum profile and the mounting bracket 20 is formed by bending aluminum profile. This combination can balance the structural performance, cost and development efficiency of the ceiling-mounted screen mounting beam 100, thereby reducing manufacturing costs and development cycle while ensuring strength.

[0030] According to some embodiments of the present invention, such as Figure 4 and Figure 8 As shown, the mounting bracket 20 defines an installation space 21 that opens toward the beam body 10, and the installation space 21 extends through the mounting bracket 20 along the length of the beam body 10, with the beam body 10 passing through the installation space 21.

[0031] The mounting bracket 20 defines an installation space 21 that opens towards the main beam 10. The installation space 21 extends through the mounting bracket 20 along the length of the main beam 10, with the main beam 10 passing through it. This allows for a large contact area between the mounting bracket 20 and the main beam 10, significantly improving the connection rigidity and resistance to torsion and bending between them. Loads from the mounting bracket 20 (such as the weight of the ceiling screen and vibrations) are evenly transmitted along the entire extension direction of the main beam 10 through the contact surface, preventing stress concentration and greatly enhancing the stability and reliability of the structure. The mounting bracket 20 itself also provides auxiliary support and reinforcement to the main beam 10, helping to prevent localized deformation and improving the overall rigidity and strength of the ceiling screen mounting beam 100.

[0032] According to some embodiments of the present invention, such as Figure 5 As shown, the mounting bracket 20 includes a first plate 22, a second plate 23, and a third plate 24. The second plate 23 is located below the main body of the crossbeam 10 and spaced apart from the main body of the crossbeam 10. The second plate 23 is connected between the first plate 22 and the third plate 24. The first plate 22 and the third plate 24 are bent toward the side of the second plate 23 facing the main body of the crossbeam 10, so that the first plate 22, the second plate 23, and the third plate 24 together define the mounting space 21. The first plate 22 and the third plate 24 are both fixed to the main body of the crossbeam 10.

[0033] The mounting frame 20 is constructed into a U-shaped or C-shaped structure with a first plate 22, a second plate 23, and a third plate 24 by bending aluminum profiles. The first plate 22 and the third plate 24 are mainly fixed to the crossbeam body 10, which can increase the connection area between the crossbeam body 10 and the mounting frame 20, and significantly improve the connection rigidity and resistance to torsion and bending between the mounting frame 20 and the crossbeam body 10.

[0034] The second plate 23 is located below and spaced apart from the main body 10 of the crossbeam, and the wall surface of the second plate 23 away from the main body 10 of the crossbeam is flat to facilitate the installation of the ceiling screen. The first plate 22, the second plate 23 and the third plate 24 together define the installation space 21 for accommodating the main body 10 of the crossbeam. The main body 10 of the crossbeam has a first cavity 28. When the main body 10 of the crossbeam is installed in the installation space 21, the main body 10 of the crossbeam and the mounting bracket 20 together define the second cavity. This can reduce the amount of material used while improving the strength of the ceiling screen mounting beam 100. In addition, multiple weight-reducing holes 27 are formed in both the main body 10 of the crossbeam and the mounting bracket 20, which can greatly reduce the weight of the ceiling screen mounting beam 100 and is conducive to the lightweight design of the vehicle.

[0035] According to some embodiments of the present invention, such as Figure 5 and Figure 6 As shown, the second plate 23 is fixedly provided with a mounting part 25, and the mounting part 25 is formed with a threaded mounting hole 26. The threaded mounting hole 26 is used to install fasteners so that the ceiling screen is fixed to the mounting bracket 20.

[0036] The mounting part 25 can be constructed as a rivet nut, sleeve, or other structure. In a specific embodiment of this utility model, the mounting part 25 is a rivet nut. The second plate 23 is fixedly provided with the mounting part 25, and a pneumatic or electric rivet gun can be used to quickly form a rivet nut on the second plate 23, thereby reducing the production difficulty of the ceiling screen mounting beam 100.

[0037] During installation, the tail of the rivet nut expands and deforms, forming a support surface on the wall of the second plate 23 away from the main body of the crossbeam 10 that is much larger than the original hole diameter. This provides a huge gripping force, enabling the connection between the mounting bracket 20 and the ceiling screen to withstand high-intensity tensile and torque forces, making it less likely to be pulled out or loosened. The mounting part 25 has a threaded mounting hole 26, which is used to install fasteners to fix the ceiling screen to the mounting bracket 20. This improves the stability of the mounting part 25, thereby effectively improving the installation stability of the ceiling screen.

[0038] According to some embodiments of the present invention, such as Figure 7 and Figure 8 As shown, there are multiple mounting parts 25, which are arranged sequentially at intervals along the length of the main body 10 of the crossbeam.

[0039] The mounting parts 25 can be multiple. In some embodiments of this utility model, there can be two, three, four, or other numbers of mounting parts 25. However, this utility model is not limited to these numbers and other numbers of mounting parts 25 are also possible, as long as there are multiple mounting parts 25. As a specific embodiment of this utility model, there can be six mounting parts 25, which are arranged sequentially and at intervals along the length of the main body 10 of the crossbeam. This arrangement can avoid high stress at a single point of connection. The arrangement of multiple mounting parts 25 can effectively distribute the weight of the ceiling screen, thereby avoiding additional overturning moments caused by the shift of the center of gravity of the ceiling screen, ensuring installation stability, and reducing deformation of the mounting frame 20 due to stress concentration. It can also provide redundancy backup. Even if one mounting part 25 fails, the other mounting parts 25 can still work normally to prevent the ceiling screen from falling off, thereby improving the safety and reliability of the vehicle.

[0040] According to some embodiments of this utility model, at least a portion of the mounting part 25 is located within the mounting space 21, which saves external space of the ceiling screen mounting beam 100, making the external outline of the mounting bracket 20 simpler and flatter, and helping to avoid interference between the mounting part 25 and surrounding components. Furthermore, since at least a portion of the mounting part 25 is located within the mounting space 21, it also prevents the mounting part 25 from being accidentally damaged by impact during the handling of the ceiling screen mounting beam 100, thereby reducing the risk of product damage.

[0041] According to some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the main body 10 of the crossbeam has an arc-shaped structure, and the main body 10 of the crossbeam protrudes in the direction away from the mounting frame 20.

[0042] The curved structure itself has higher torsional stiffness than the planar structure. When the load is asymmetrical or there is lateral force, the curved beam body 10 can better resist torsional deformation, thus improving the stability of the ceiling screen. It also optimizes the force transmission path of the beam body 10, guiding the concentrated load from the middle along a smooth arc to the fixed support points at both ends, avoiding the stress concentration problem that may occur at the corners of straight beams, thereby effectively improving the safety and reliability of the entire ceiling screen installation beam 100.

[0043] The vehicle roof structure 200 according to an embodiment of the present utility model includes: The first side beam 201 and the second side beam 202 are arranged at intervals along the width direction of the vehicle. The ceiling screen mounting beam 100 is the same as the ceiling screen mounting beam 100 for vehicles described in the above embodiment. The main body 10 of the beam is fixedly connected between the first side beam 201 and the second side beam 202. The mounting bracket 20 is used to install the ceiling screen of the vehicle.

[0044] The main body 10 of the crossbeam is used to fix the crossbeam between the first side beam 201 and the second side beam 202, and can correspond to the position of the ceiling screen. The mounting bracket 20 is used to install the ceiling screen of the vehicle, so as to install the ceiling screen onto the ceiling screen mounting crossbeam 100. Furthermore, the crossbeam main body 10, which is formed by extrusion of aluminum profile, and the mounting bracket 20, which is formed by bending aluminum profile, can be used together to balance the structural performance, cost and development efficiency of the ceiling screen mounting crossbeam 100, thereby reducing the manufacturing cost and development cycle of the top cover structure 200 while ensuring strength.

[0045] According to some embodiments of the present invention, such as Figure 1 As shown, there are multiple ceiling screen mounting beams 100, which are arranged at intervals along the length of the vehicle.

[0046] The ceiling screen mounting beams 100 can be multiple. In some embodiments of this utility model, there can be two, three, four, or other numbers of ceiling screen mounting beams 100. However, this utility model is not limited to this, and there can be other numbers of ceiling screen mounting beams 100, as long as there are multiple ceiling screen mounting beams 100. As a specific embodiment of this utility model, there can be two ceiling screen mounting beams 100. The two ceiling screen mounting beams 100 are arranged alternately along the length of the vehicle. The two ceiling screen mounting beams 100 are located at both ends of the ceiling screen, and both ceiling screen mounting beams 100 are fixedly connected to the ceiling screen. This arrangement can more evenly distribute the impact force on the ceiling screen, which is beneficial to improving the installation stability of the ceiling screen. It can also separate the middle part of the ceiling screen from the ceiling screen mounting beams 100, preventing the ceiling screen mounting beams 100 from covering the heat dissipation surface of the ceiling screen, which is beneficial to the heat dissipation of the ceiling screen, and thus can effectively extend the service life of the ceiling screen.

[0047] The vehicle according to the present utility model includes the roof structure 200 of the vehicle in the above embodiment. The crossbeam body 10 formed by extrusion of aluminum profile and the mounting bracket 20 formed by bending aluminum profile are used together to balance the structural performance, cost and development efficiency of the ceiling screen mounting crossbeam 100, thereby reducing the manufacturing cost and development cycle of the vehicle while ensuring strength.
