[0002] Electric tricycles, as a convenient and practical means of transportation, are widely used in daily life and logistics. To improve driver comfort and the overall aesthetics of the vehicle, electric tricycles are usually equipped with curtains, especially for the roof, primarily double-opening curtains. This provides shade and rain protection while increasing privacy inside the vehicle. However, current technology presents several inconveniences and problems with the installation structure of the curtains and roof frame on electric tricycles. Firstly, traditional curtain installation methods are often complex, requiring multiple tools and a considerable amount of time, which undoubtedly increases the difficulty and cost for users.
[0003] On the other hand, the sturdiness of the connection between the curtain and the frame is also a problem that urgently needs to be solved. Because electric tricycles are subject to various bumps and vibrations during operation, if the connection between the curtain and the frame is not sturdy enough, the curtain may loosen or fall off, which not only affects the driver's experience but may also pose a safety hazard.
[0004] Therefore, in view of the problems of inconvenient installation and weak connection of door curtains in the existing technology, this utility model proposes a new installation structure for electric vehicle door curtains. Utility Model Content

[0026] 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.
[0027] Please see Figures 1 to 5 Example 1 illustrates an installation structure for an electric vehicle door curtain, comprising a double-opening door curtain 1. The double-opening design makes the door curtain more flexible and convenient to open and close, allowing the driver and passengers to easily enter and exit the electric vehicle, thus improving ease of use. The door curtain is installed on the roof frame 2, which serves as the supporting structure for the door curtain, capable of withstanding its weight and external forces such as wind, ensuring the long-term reliability of the door curtain. Installing the door curtain on the roof frame ensures its stability and sturdiness, maintaining its position even while the vehicle is in motion.
[0028] The frame includes a hollow main tube 2-1 and a hollow secondary tube 2-2, which are a connected, integrated structure. The hollow structure of the main and secondary tubes reduces the weight of the frame, making the electric vehicle lighter and improving energy efficiency and driving range. A curtain connector 3 is installed on the secondary tube. This connector acts as a bridge between the curtain and the frame, ensuring a reliable connection and stability. The connector design makes curtain installation and removal easier and quicker, facilitating maintenance and replacement.
[0029] The upper part of the curtain connector is connected to the secondary tube, and the lower part of the curtain clip is connected to the curtain 1. This top-to-bottom connection allows the curtain connector to evenly distribute the force on the curtain, avoiding damage caused by excessive local stress. The upper connection to the secondary tube ensures the stability of the connector, while the lower connection to the curtain allows for flexible opening and closing of the curtain.
[0030] Preferably, the cross-sectional area of the main pipe is larger than that of the secondary pipe, ensuring the structural strength and stability of the frame and better supporting the weight of the curtain and resisting external wind forces. An inwardly recessed groove is formed at the junction of the main and secondary pipes. This cleverly provides a locking and limiting function for the curtain connectors, ensuring they are firmly fixed to the frame and not easily loosened or detached. This design not only improves the stability and reliability of the curtain installation but also simplifies the installation process, making installation more convenient and faster. Simultaneously, the groove design enhances the aesthetics of the frame and improves the overall quality of the electric vehicle.
[0031] More preferably, the curtain connector 3 includes an open slot 3-1 located at the top and a curtain connecting part 3-2 located below the slot. The cross-section of the slot has the same shape as the cross-section of the secondary tube, and the inner diameter of the slot has the same geometric dimension as the outer diameter of the secondary tube. The lateral opening size of the slot is less than 1 / 2 of the outer diameter of the secondary tube.
[0032] More preferably, the curtain connecting part 3-2 extends downward along one edge of the slot or the middle of the slot.
[0033] More preferably, the curtain is connected to the curtain connecting part by adhesive or hot melt welding.
[0034] More preferably, the curtain connecting part 3-2 is provided with a fixing hole 3-20, and a fastener 3-21 connected to the curtain is installed in the fixing hole. The fastener can be a bolt, rivet or nail for fixing, or the curtain can be directly sewn together with the curtain connecting part using a sewing thread.
[0035] More preferably, the frame 2 includes a straight segment 2-3 and an arc-shaped bending segment 2-4, and both the straight segment and the arc-shaped bending segment are provided with the aforementioned curtain connector.
[0036] More preferably, the straight section and the curved bending section of the curtain connector are an integral structure. To facilitate bending of the curved bending section, a groove for easy bending is provided on the curtain connector on the inner side of the curved bending section.
[0037] Example 2, please refer to Figure 6 In this embodiment, the straight section 3-3 and the curved bending section 3-4 of the curtain connector are separate structures. The remaining features are the same as in embodiment 1. The straight section and the curved bending section of the curtain connector can be produced independently, or the straight section can be heated and bent into a curved bending section. To facilitate bending of the curved bending section, a groove for easy bending is provided on the curtain connecting part inside the curved bending section.
[0038] Example 3, please refer to Figure 7The frame includes a straight segment 2-1 and an arc-shaped bend segment 2-2. The straight segment is provided with the aforementioned curtain connector 3. A first nylon hook and loop fastener 4-1 is fixedly provided on the arc-shaped bend segment of the frame sub-tube. Corresponding to the arc-shaped bend segment of the frame sub-tube, the inner side of the curtain is provided with a second nylon hook and loop fastener 4-2 that cooperates with the first nylon hook and loop fastener. This ensures that the curtain fits tightly against the frame at the arc-shaped segment. The remaining features are the same as in Embodiment 1.
[0039] Example 4, please refer to Figure 8 Based on the above embodiments 1 to 3, the main tube and the secondary tube of the frame in this embodiment can also adopt the following technical features: the cross-sectional shape and geometric dimensions of the main tube are the same as those of the secondary tube, and an inwardly recessed groove is formed at the junction of the main tube and the secondary tube.
[0040] 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.
