Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle technology, and in particular relates to an electric vehicle roof with a door. Background Technology

[0002] With the rapid rise of the electric vehicle industry, the roof and doors, as two core components of the electric vehicle body, especially for electric tricycles, require advanced design and manufacturing technologies. However, examining the current design of the roof and doors of electric vehicles with doors reveals many challenges that urgently need to be overcome.

[0003] The frame of the roof of a traditional electric vehicle with doors is mostly constructed using a square tube bending and welding process. During the welding process, the presence of weld seams and the influence of the heat-affected zone make it difficult for the weld joint to reach the strength standard of the base material. This process also easily breeds welding defects such as cracks, porosity, and slag inclusions, severely weakening the structural safety of the roof. Furthermore, during the bending process, the stress on each side of the square tube is difficult to distribute evenly, making it difficult to precisely control the shape and dimensions, leading to twisting, deformation, and even breakage. Such deformation not only damages the aesthetic appearance of the roof but can also cause improper fit between the roof and other vehicle components, especially the doors.

[0004] Traditional designs often fail to ensure adequate sealing in the installation and sealing of the roof and doors. Due to improper handling at the joint between the roof and doors, leaks and air leaks frequently occur, severely impacting driver comfort and impairing the overall performance of the electric vehicle. Furthermore, over long-term use, uneven stress or material aging can cause deformation of the roof and doors, further exacerbating the sealing problem.

[0005] In summary, the existing design of the roof and door integration in electric vehicles has many drawbacks, especially in terms of installation, sealing, and deformation, which seriously restricts the overall performance and lifespan of the electric vehicles. Therefore, there is an urgent need for a novel design that integrates the roof and door of electric vehicles to overcome the challenges of existing technology and improve the overall performance, lifespan, and driver comfort of electric vehicles.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0025] Please see Figures 1 to 5An electric vehicle roof with a door includes a roof frame 10 for mounting protective panels, an A-pillar assembly 20, and a door 30. The roof frame 10 includes at least two side frames 110, connected by roof beams 120 for mounting protective panels. This design provides basic structural support for the roof, ensuring stable installation of the protective panels. The combination of the side frames and roof beams forms a robust frame capable of withstanding various external forces on the roof, such as wind pressure and vibration, ensuring the overall stability and durability of the roof. The side frames include a hollow main pipe 111 and a hollow secondary pipe 112, which are connected as a single unit. The diameter of the main pipe is larger than that of the secondary pipe, with a preferred cross-sectional area ratio of 5:3 to 2:1. Due to its unique hollow structure and integrated design, it can better maintain shape and dimensional stability during bending. In particular, the design of the deformation groove structure and transition arc effectively reduces deformation problems caused by stress concentration, improving processing accuracy and consistency. This not only reduces the cost of correction and adjustment during the production process, but also improves the overall quality and aesthetic appearance of the roof. The main pipe is located above and fixedly connected to the roof crossbeam, while the secondary pipe is located below the main pipe, serving as the door frame sealing surface.

[0026] The A-pillar assembly not only provides support for the connection between the roof and the front of the vehicle, but also enhances the vehicle's aesthetics and the driver's field of vision through the rear window and A-pillar guard plate. The fixed connection between the A-pillar frame and the side frame ensures the overall stability of the roof and the front of the vehicle. The A-pillar assembly 20 includes an A-pillar frame 201 fixedly connected to the side frame of the roof frame, a rear window 202 mounted on the A-pillar frame, and an A-pillar guard plate 203. The door is hinged to the A-pillar frame, and when the door is closed, the inner edge of the door seals against the outer side of the sub-tube. This design ensures a tight fit when the door is closed, improving the door's sealing and stability. The sub-tube, as the sealing surface of the door frame, forms an effective sealing barrier with the inner edge of the door, preventing the intrusion of external substances and improving the comfort of the cab and the overall sealing performance of the vehicle.

[0027] Preferably, this technical feature achieves a stable connection with the roof beam by welding a crossbeam connector 130 to the main pipe of the side frame, thereby enhancing the structural strength of the vehicle roof. Simultaneously, a frame fixing seat 140 at at least one end of the main pipe ensures a secure connection between the side frame and the frame, improving the overall stability and safety of the vehicle. This design makes the vehicle structure more compact and robust, effectively improving the vehicle's durability and reliability.

[0028] This design enables a flexible connection between the roof and the electric vehicle frame. The roof can be disassembled and installed independently of the frame, significantly improving its modularity and maintainability. When repair or replacement is needed, the roof can be easily and quickly removed from the frame without extensive disassembly of the entire electric vehicle, saving repair time and costs, and enhancing the vehicle's ease of use and flexibility.

[0029] Preferably, the A-pillar frame is detachably connected to the roof frame and the electric vehicle frame. This detachable connection design improves the modularity of the A-pillar frame, facilitating maintenance and replacement, while also enhancing the overall vehicle's flexibility and maintainability, and reducing maintenance costs and time. More preferably, the connection ends of the A-pillar frame to the side frame of the roof frame and to the electric vehicle frame are provided with mounting brackets 204, which are fixedly connected to the side frame using fasteners.

[0030] Preferably, the A-pillar frame is welded and fixedly connected to the side frame of the roof frame and the electric vehicle frame, respectively. This achieves an integrated design of the A-pillar frame, roof, and electric vehicle frame. This welding connection method makes the entire product more stable and reliable. Selling it as a single unit not only enhances the product's structural strength but also expands its diversity, meeting the personalized needs of different customers for the overall structure and appearance of the electric vehicle.

[0031] Preferably, a sealing member 40 is provided between the inner edge of the door and the sub-tube. This effectively improves the sealing performance between the door and the roof. The sealing member can tightly fit the contact surface between the door and the sub-tube, preventing rainwater, dust and other external substances from entering the vehicle, thereby enhancing the comfort of the cab and the overall sealing of the vehicle. In this embodiment, a D-shaped sealing strip is preferably fixed to the inner edge of the door.

[0032] 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.
