[0002] In today's society, electric tricycles or small four-wheeled vehicles are popular due to their compact size and ease of driving. However, with the increasing popularity of electric tricycles or small four-wheeled vehicles, problems with their door design have gradually become apparent. Currently, tricycle doors generally use an outer metal panel with an inner panel installed inside. While this split design ensures the door's strength and durability to some extent, it also has many shortcomings.

[0003] On the one hand, metal-structured car doors are quite heavy. As a crucial component of a vehicle, the weight of the door directly impacts the overall vehicle weight. Excessively heavy doors not only increase the vehicle's burden but also waste energy. In the electric vehicle sector, efficient energy utilization is paramount; excessively heavy doors can shorten the driving range of electric vehicles, negatively affecting the user experience.

[0004] On the other hand, the separate structure of the inner and outer panels brings several drawbacks. First, the separate structure requires additional connectors and assembly processes, increasing manufacturing costs and production time. These connectors not only increase the weight of the door but may also become potential points of failure, affecting the door's reliability and durability. Second, during long-term use, the connection between the inner and outer panels may loosen or break due to vibration, impact, and other factors, leading to problems such as abnormal noises and shaking, affecting the user's driving experience. Furthermore, the separate structure makes repair and replacement of doors more complicated, requiring the disassembly and reinstallation of multiple components, increasing the difficulty and cost of maintenance.

[0005] Therefore, a new type of car door design is urgently needed to solve the above problems. This utility model proposes an integrated car door for electric vehicles, which aims to reduce the weight of the door by improving its structure and materials, and to eliminate the defects caused by the separate structure of the inner and outer protective panels.

[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 5 An integrated door for an electric vehicle includes an outer protective panel 1 and an inner protective panel 2. The upper part of the outer and inner protective panels is provided with a window 3 for installing a windshield curtain or a windshield. The outer and inner protective panels are integrally blow-molded, and there is a hollow cavity between the outer and inner protective panels. A reinforcing frame 4 is provided on the inner side of the inner protective panel. The outer and inner protective panels are provided with door lock mounting grooves 1-1 or mounting holes.

[0026] The following is a detailed description of each technical feature:

[0027] 1. The outer and inner protective panels are blow-molded as a single piece:

[0028] Technical Benefits: Traditional car door panels are typically designed as separate units, requiring additional connectors and assembly processes. This not only increases manufacturing costs but can also lead to rattling and shaking due to loose or damaged connectors. This new invention utilizes integrated blow molding technology to form the outer and inner panels in a single process, eliminating connectors, simplifying the assembly process, and improving the overall reliability and durability of the door. Furthermore, the integrated blow molding technology also results in a smoother door surface and enhanced aesthetics.

[0029] 2. The space between the outer and inner protective plates is a hollow cavity:

[0030] Technical Benefits: The hollow cavity design effectively reduces the weight of the door while ensuring its strength. For electric vehicles, reducing door weight means reducing energy consumption and increasing driving range. Furthermore, the hollow cavity also provides some sound and heat insulation, enhancing driving comfort.

[0031] 3. The inner side of the inner liner is equipped with a reinforcing frame:

[0032] Technical Benefits: The reinforced frame design further enhances the strength and rigidity of the door, making it less prone to deformation under external forces. This is crucial for ensuring the stability and safety of the door during long-term use. Simultaneously, the reinforced frame provides a robust mounting base for other door components, such as door locks and window frames.

[0033] 4. The outer and inner protective panels are provided with door lock mounting slots or mounting holes:

[0034] Technical Benefits: The design of the door lock mounting slot or hole allows for easy installation of door locks and other components onto the car door without additional processing or modification. This not only simplifies the door assembly process but also improves assembly efficiency and accuracy.

[0035] To further enhance the effectiveness of this utility model, the following embodiments can also be adopted, as detailed below:

[0036] Preferably, the reinforcing frame is fixedly connected to the inner lining panel using fasteners 5. During manufacturing, the inner lining panel has pre-fabricated connecting posts or reinforcing connecting parts (solid bosses with a thickness greater than the inner lining panel thickness, etc.). The reinforcing frame is then fixedly connected to the inner lining panel using fasteners, ensuring a strong connection between the reinforcing frame and the inner lining panel, thus improving the overall structural strength and stability of the door. The fastener connection method is simple and reliable, easy to install and disassemble, and facilitates door maintenance and repair. Simultaneously, the fastener connection effectively transmits external forces on the door, allowing the reinforcing frame to fully exert its supporting function and ensuring the safety and reliability of the door during long-term use.

[0037] Preferably, the reinforcing frame 4 includes at least one horizontal frame beam 4-1 and a vertical frame beam 4-2 for connecting the horizontal frame beam, wherein the vertical frame beam is located on the hinge side of the door; the cross-section of the horizontal and vertical frame beams is circular, elliptical, or directional steel tubing. By providing at least one horizontal frame beam and a connecting vertical frame beam, a stable support structure is formed inside the door. The vertical frame beam, located on the hinge side of the door, effectively enhances the strength and rigidity of the door at the hinge, preventing deformation or damage during frequent opening and closing. The horizontal frame beam works in conjunction with the vertical frame beam to jointly bear various external forces on the door, ensuring the overall stability and durability of the door. This frame structure design is reasonable and can effectively improve the service life and safety of the door.

[0038] Preferably, a diagonal tie rod 4-3 is provided between the horizontal and vertical frame beams. The diagonal tie rod enhances the connection strength between the horizontal and vertical frame beams, further improving the overall rigidity and stability of the door. The diagonal tie rod can effectively resist the torsional deformation of the door under stress, ensuring the structural integrity of the door under complex stress environments.

[0039] Preferably, the inner side of the inner panel is integrally provided with a frame receiving groove 4-4 for accommodating the reinforcing frame. This integrally provided frame receiving groove provides a precise and stable installation position for the reinforcing frame, ensuring a tight fit between the reinforcing frame and the inner panel, thus improving the overall structural strength and assembly accuracy of the door. This integrated design simplifies the assembly process, reduces the use of additional fasteners, and lowers manufacturing costs. Simultaneously, the frame receiving groove also provides some protection for the reinforcing frame, preventing damage from external impacts during use, thereby extending the service life of the door.

[0040] Preferably, one of the frame receiving slots extends from the door lock mounting slot or mounting hole towards the vertical frame beam. This technical feature brings significant ease of use and structural optimization. The frame receiving slot extending from the door lock mounting slot or mounting hole towards the vertical frame beam not only enhances the structural strength of this area but also provides a concealed and secure path for the door lock lever or cable. This design allows the driver to open the door without having to reverse their hand, greatly improving ease of operation and comfort. At the same time, the concealed installation of the lever or cable maintains the neatness and aesthetics of the door interior, enhancing the overall design. This technical feature embodies a perfect combination of human-centered design and structural functionality.

[0041] For preferred options, please refer to [link / reference]. Figure 6The door lock mounting slot is equipped with a door lock mounting plate 1-2 that is integrated with the inner and outer protective plates. This ensures the accuracy and firmness of the door lock installation position, effectively preventing safety hazards caused by loosening or displacement of the door lock during use. This integrated design not only improves the assembly efficiency of the vehicle door but also reduces the use of additional fasteners, lowering manufacturing costs. Simultaneously, the one-piece molded door lock mounting plate enhances the overall aesthetics of the vehicle door, improving product quality and market competitiveness.

[0042] For preferred options, please refer to [link / reference]. Figure 7 The inner protective panel has a sealing member 5 installed on its edge. Preferably, the sealing member is a D-shaped sealing strip. In this embodiment, the sealing member is placed on the side of the door, so that when the door is closed, the sealing member can directly abut against the outer side of the door frame to achieve a seamless seal. The D-shaped cross-section enhances the fit, which not only meets the sealing requirements but also simplifies the installation process, providing a more efficient and reliable solution for sealing electric vehicle doors.
