[0021] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0022] Embodiment 1, please refer to Figures 1 to 6 A sealing device for electric vehicle door, comprising a vehicle door 1 and a door frame 2, the door frame comprises a hollow structure main pipe 2-1 and a hollow structure auxiliary pipe 2-2, the main pipe and the auxiliary pipe are an integrated structure in communication; the diameter of the main pipe is greater than that of the auxiliary pipe; the bent main pipe is located above, the auxiliary pipe is located below the main pipe, the edge of the vehicle door abuts against the auxiliary pipe; a sealing member 3 is arranged between the vehicle door and the auxiliary pipe.

[0023] In the above structure, first of all, from the structure design of the main pipe and the auxiliary pipe, the utility model adopts an integrated design of hollow structure, the diameter of the main pipe is greater than that of the auxiliary pipe, and the bent main pipe is located above and the auxiliary pipe is located below. The door frame can be more stable when bearing the opening and closing force of the vehicle door, effectively reducing the deformation and distortion of the door frame. At the same time, as the door frame sealing surface of the vehicle door, the smaller diameter design of the auxiliary pipe makes the vehicle door more closely fit the surface of the auxiliary pipe when closing, thereby greatly improving the sealing effect. This design not only enhances the strength and stability of the door frame, but also effectively prevents the intrusion of external substances such as rainwater and dust, ensuring the cleanliness and comfort of the cab.

[0024] Secondly, the utility model also makes an important innovation in the convenience of installing the sealing member. The sealing member is ingeniously arranged between the vehicle door and the auxiliary pipe, which not only ensures the sealing effect, but also makes the installation process extremely simple and fast. Since the contact surfaces of the sealing member with the vehicle door and the auxiliary pipe are carefully designed and treated, no complex tools or steps are required during installation, and the sealing member can be simply placed in the specified position. This design not only improves production efficiency, but also reduces production cost, providing strong support for large-scale production and application of electric vehicles.

[0025] The preferred in embodiment 1, please refer to Figure 5 and Figure 6, the edge of the door is provided with a sealing member 3, and the sealing member is in abutment with the auxiliary pipe to achieve door sealing after the door is closed. Further preferably, the cross section of the sealing member is D-shaped. Compared with the previous embodiment, the sealing member is directly placed on the side of the door in this embodiment, so that the sealing strip can be in abutment with the auxiliary pipe more directly when the door is closed, achieving seamless sealing. The D-shaped cross section enhances the fit, not only meeting the sealing requirements but also simplifying the installation process, providing a more efficient and reliable solution for electric vehicle door sealing.

[0026] In embodiment 2, please refer to Figure 7 , the sealing member 3 is installed on the auxiliary pipe and includes an open clamping sleeve 3-1 and a sealing strip 3-2 integrated with the clamping sleeve, the opening of the clamping sleeve is smaller than the radius of the auxiliary pipe, and the sealing strip is in abutment with the inner side of the edge of the door to achieve sealing. Further preferably, the sealing strip is hollow.

[0027] The design of the open clamping sleeve 3-1 allows the sealing member to be easily clamped into the auxiliary pipe without the need for complex installation steps or additional fixing devices. The opening of the clamping sleeve is smaller than the radius of the auxiliary pipe, ensuring stable installation of the sealing member on the auxiliary pipe and effectively preventing the sealing member from falling off or shifting during use.

[0028] Further, the hollow design of the sealing strip 3-2 not only reduces the overall weight of the sealing member but also improves its sealing performance. The hollow structure allows the sealing strip to deform more easily when subjected to the closing pressure of the door, thereby more closely fitting the inner side of the edge of the door. This close fit effectively prevents the intrusion of external substances such as rain and dust, further improving the sealing and comfort of the cab. At the same time, the hollow sealing strip also has good elasticity and durability, which can maintain its sealing performance for a long time, prolonging the service life of the sealing member.

[0029] Further preferably, the opening direction of the sealing strip clamping sleeve forms an angle of 15-45° with the vertical center of the clamping sleeve. Due to the angle formed between the opening direction and the vertical center, the sealing strip 3-2 will be in contact with the inner side of the edge of the door in advance after installation. This design allows the sealing strip to be in a pre-compressed state before the door is closed, which is beneficial to the deformation of the sealing strip to adapt to the shape of the door when the door is closed.

[0030] This pre-contact and pre-compression design not only enhances the fit of the sealing strip with the inner side of the edge of the door, but also improves the sealing effect. It ensures that even in the case of rapid closing of the door or slight deviation, the sealing strip can quickly and tightly fit, effectively preventing the intrusion of external substances such as rain and dust. At the same time, this design also prolongs the service life of the sealing strip and reduces wear caused by frequent deformation.

[0031] Meanwhile, since the opening direction forms a certain angle with the vertical center, the clamping sleeve is fixed more firmly in the sub-pipe and is not easy to fall off due to vibration or external force, thereby ensuring long-term stability of the sealing member.

[0032] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
