Description

Technical Field

[0001] This utility model belongs to the field of vehicle door sealing technology, and mainly relates to a door frame sealing structure for a frameless door of an electric vehicle. Background Technology

[0002] For frameless car doors, since there are no window frame sheet metal, the door frame sealing strip plays a crucial role as the main sealing component in the door frame. The sealing strip at the top of the door frame directly cooperates with the door glass to form a seal. Therefore, the water sealing performance, dust sealing performance and wear resistance of the door frame sealing strip are all subject to higher requirements.

[0003] In frameless car doors, the door frame sealing strip serves as a sealing structure to achieve a seal. For example, the patent document with authorization announcement number CN215883282U provides a door frame sealing strip for frameless car doors, which is installed on the door frame of the vehicle to form a seal between the door and the door frame. Since the sealing strip is made of rubber material, and the side sheet metal is only in a simple abutting and tight contact with the first and second water seal structures, water will accumulate in the cavity between the insertion cavity and the abutting lip of the sealing strip after long-term use, which can easily cause bacteria growth and odor. Utility Model Content

[0004] The purpose of this invention is to design a door frame sealing structure for a frameless door of an electric vehicle, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: it includes a sealing strip and an adhesive tape adhered to the sealing strip. The sealing strip is connected to the side panel sheet metal via the adhesive tape. The sealing strip is connected to the side interior panel via an overlap. The sealing strip is provided with a transverse sealing plate. The top of the side panel sheet metal is in close contact with the bottom of the transverse sealing plate. A sealing body is also provided on the end of the sealing strip away from the transverse sealing plate. When the door is closed, the door presses against the sealing body.

[0006] Furthermore, a sealing sheet is wrapped around the upper outer wall of the side panel sheet metal, and the sealing strip is fixed to the sealing sheet by the tape. The top of the sealing sheet is tightly attached to the transverse sealing plate. A raised part is provided on the bottom side of the sealing sheet with the tape attached. The raised part is oriented towards the sealing body. A protrusion is provided at the bottom of the sealing body. The protrusion abuts against the top of the raised part.

[0007] Furthermore, the sealing sheet is an elastic sheet, and an elastic cavity is provided between the top of the side sheet metal and the sealing sheet, with the outer top of the elastic cavity in close contact with the transverse sealing plate.

[0008] Furthermore, the sealing body is D-shaped, and includes a vertical sealing plate and an arc-shaped sealing plate fixedly connected to the vertical sealing plate. The horizontal sealing plate is fixedly connected to the side of the vertical sealing plate away from the arc-shaped sealing plate. The tape is adhered to the vertical sealing plate. The protrusion is located at the bottom of the vertical sealing plate. When the car door is closed, the car door presses against the arc-shaped sealing plate.

[0009] Furthermore, the interior of the sealing body is provided with reinforcing ribs, the two ends of which are fixed to the arc-shaped sealing plate and the vertical sealing plate, respectively.

[0010] Furthermore, the connection between the reinforcing rib and the arc-shaped sealing plate is higher than the transverse sealing plate, while the connection between the reinforcing rib and the vertical sealing plate is lower than the transverse sealing plate.

[0011] Furthermore, the interior of the sealing body is provided with a crescent-shaped deformation cavity, the bottom end of which points towards the protrusion.

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] Example: Please refer to Figure 1 A door frame sealing structure for a frameless door of an electric vehicle includes a sealing strip and adhesive tape 13 adhered to the sealing strip. The sealing strip is connected to a side panel 10 via the adhesive tape 13. The sealing strip is also connected to a side interior panel 6 via an overlap portion 5. A transverse sealing plate 7 is provided on the sealing strip. The top of the side panel 10 is tightly attached to the bottom of the transverse sealing plate 7. A sealing body 1 is also provided on the end of the sealing strip away from the transverse sealing plate 7. When the door 4 is closed, the door 4 presses against the sealing body 1. The sealing strip is generally made of rubber through one-piece injection molding. In this embodiment, the sealing strip is preferably processed using a rubber injection molding process. After the sealing strip is processed, The tape 13 is adhered to the sealing strip; therefore, the sealing strip of this utility model achieves initial sealing by adhering the tape 13 to the side sheet metal 10. Secondly, the top of the side sheet metal 10 is tightly attached to the bottom of the transverse sealing plate 7, thereby achieving secondary sealing. Furthermore, by using the tape 13 for adhesion and simultaneously eliminating the structural design of the abutment lip and the insertion cavity, the sealing strip can still be connected stably, while also eliminating the phenomenon of water accumulation in the cavity between the insertion cavity and the abutment lip, which would cause bacterial growth and odor. At the same time, it also eliminates the phenomenon of water overflow in the cavity between the insertion cavity and the abutment lip.

[0018] In addition, a sealing sheet 9 is wrapped around the upper outer wall of the side panel 10. The sealing strip is fixed to the sealing sheet 9 by tape 13. The top of the sealing sheet 9 is tightly attached to the transverse sealing plate 7. The bottom of one side of the sealing sheet 9 with tape 13 is provided with a raised part 11. The raised part 11 is facing the sealing body 1. The bottom of the sealing body 1 is provided with a protrusion 12. The protrusion 12 abuts against the top of the raised part 11. The tight contact between the raised part 11 and the protrusion 12 further prevents water from entering, thereby improving the sealing performance of the sealing strip. In addition, the sealing sheet 9 is an elastic sheet. An elastic cavity 8 is provided between the top of the side panel 10 and the sealing sheet 9. The outer top of the elastic cavity 8 is tightly attached to the transverse sealing plate 7, which improves the elastic deformation capacity at the connection between the sealing sheet 9 and the transverse sealing plate 7. This facilitates installation and effectively increases the contact area between the sealing sheet 9 and the transverse sealing plate 7, ensuring that both are always under elastic compression deformation, thereby improving the sealing performance between them. The sealing sheet 9 can be fixed to the side panel 10 by welding.

[0019] In this embodiment, the sealing body 1 is D-shaped and includes a vertical sealing plate 2 and an arc-shaped sealing plate 3 fixedly connected to the vertical sealing plate 2. A transverse sealing plate 7 is fixedly connected to the side of the vertical sealing plate 2 away from the arc-shaped sealing plate 3. The tape 13 is adhered to the vertical sealing plate 2. The protrusion 12 is located at the bottom of the vertical sealing plate 2. When the car door 4 is closed, the car door 4 presses against the arc-shaped sealing plate 3. Compared with the traditional thumb-shaped sealing body 1, the D-shaped sealing body 1 can deform uniformly when the car door 4 is closed, thereby reducing the vertical movement of the vertical sealing plate 2. This allows the force generated by the deformation of the sealing body 1 to act more laterally on the vertical sealing plate 2, thereby improving the sealing performance between the vertical sealing plate 2 and the side sheet metal 10 and effectively preventing the tape 13 from slipping and falling off.

[0020] In addition, the interior of the sealing body 1 is provided with reinforcing ribs 14, the two ends of which are fixed to the arc-shaped sealing plate 3 and the vertical sealing plate 2, respectively, thereby improving the strength of the sealing body 1 and thus increasing its service life. At the same time, the reinforcing ribs 14 also facilitate uniform deformation of the sealing body 1. The connection between the reinforcing ribs 14 and the arc-shaped sealing plate 3 is higher than the transverse sealing plate 7, while the connection between the reinforcing ribs 14 and the vertical sealing plate 2 is lower than the transverse sealing plate 7, thus dividing the interior of the sealing body 1 into two chambers of different sizes. The larger chamber is beneficial to improving the elastic deformation capacity of the sealing body 1, while the smaller chamber is beneficial to improving the strength of the sealing body 1. The interior of the sealing body 1 is provided with a crescent-shaped deformation cavity 15, the bottom end of which points towards the protrusion 12. When the door 4 is closed, the crescent-shaped deformation cavity 15 deforms, thereby applying force to the protrusion 12, thereby increasing the compressive strength between the raised part 11 and the protrusion 12, and thus improving the sealing performance between them.

[0021] Please refer to Figures 2-5 The assembly process of the sealing structure is as follows: First, the sealing body 1 and the tape 13 are bonded together on the production line; Second, the sealing body 1 with the tape 13 bonded together is bonded to the sealing sheet 9 on the final assembly line using the tape 13; Third, the side interior panel 6 is inserted into the overlapping part 5; Fourth, after the door 4 is closed, the sealing body 1 is squeezed to form a sealing structure.

[0022] Working principle: The sealing strip in this utility model is connected to the side sheet metal 10 by tape 13. At the same time, the structural design of the abutment lip and the insertion cavity is eliminated. This ensures that the sealing strip can still be connected stably, while also eliminating the phenomenon of water accumulation in the cavity between the insertion cavity and the abutment lip, which can cause bacteria growth and odor. It also eliminates the phenomenon of water overflow in the cavity between the insertion cavity and the abutment lip.
