Description

Technical Field

[0001] The utility model relates to the technical field of automobile sealing strips, in particular to a frameless vehicle door glass sealing strip. Background Art

[0002] One of the most notable features of frameless door models is that the side glass is flush with the B / C pillars, and the glass edge is not wrapped by the door frame. From the side, it looks like a whole surface without steps, which makes it look smoother and more beautiful. It also greatly helps to reduce the wind resistance of the entire vehicle. With the gradual improvement of people's aesthetic concepts, more and more frameless door models are now accelerating into our lives.

[0003] For frameless door models, the B / C-pillar sealing strips are usually assembled to the B / C-pillar trim panels, and then the assembly is assembled to the vehicle body. The B / C-pillar sealing strips play a vital role in glass sealing.

[0004] The cross-section of a conventional B / C-pillar sealing strip is generally composed of an EPDM extruded body + surface spraying. The B / C-pillar sealing strip is dynamically matched and sealed with the glass lift. Since the surface flatness of the surface coating is difficult to guarantee, the lifting and lowering of the door glass will cause severe wear of the surface coating of the sealing strip during long-term use, resulting in reduced sealing performance of the door glass and abnormal noise when the glass is lifted or lowered.

[0005] Based on this, the utility model designs a frameless vehicle door glass sealing strip to solve the above problems. Utility Model Content

[0021] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0022] See also Figure 1The utility model provides a technical solution: a frameless door glass sealing strip, comprising a mounting end 1 for connecting with a B / C pillar of a vehicle body, a first contact end 2 for contacting and sealing with a side of the door glass facing the B / C pillar of the vehicle body, and a second contact end 3 for contacting and sealing with a side of the door glass facing the inside of the vehicle body, wherein the first contact end 2 and the second contact end 3 are both provided with an anti-wear layer 4 on a side for contacting with the door glass, wherein the anti-wear layer 4 is integrally formed with the frameless door sealing strip, and the anti-wear layer 4 is integrally formed on the surfaces of the first contact end 2 and the second contact end 3. Compared with traditional surface coatings, the integrally formed anti-wear layer 4 has a smoother surface, a lower friction coefficient, and better anti-wear performance, and can greatly extend the service life of the sealing strip.

[0023] Specifically, the sealing strip includes a mounting end 1, a first contact end 2 and a second contact end 3, the sealing strip is connected to the B / C pillar of the vehicle body through the mounting end 1, the first contact end 2 and the second contact end 3 are fixedly mounted on the end of the mounting end 1 away from the B / C pillar of the vehicle body, the first contact end 2 and the second contact end 3 are used to contact with the door glass to form an extrusion seal when the door is closed, the first contact end 2 is mounted on a side of the mounting end 1 away from the inside of the vehicle body to contact with a side of the door glass facing the B / C pillar of the vehicle body to form a seal, and the second contact end 3 is mounted on a side of the mounting end 1 close to the inside of the vehicle body to contact with a side of the door glass facing the inside of the vehicle body to form a seal, so as to ensure the sealing and sound insulation effect between the door glass and the B / C pillar of the vehicle body when the frameless door is closed, and during the process of the door glass being raised and lowered The door glass will have sliding friction with the surfaces of the first contact end 2 and the second contact end 3. In order to reduce friction and prevent the sealing strip from being worn, an anti-wear layer 4 is formed on the side of the first contact end 2 and the second contact end 3 that is used to contact the door glass. The anti-wear layer 4 is a modified plastic layer with a thickness of 0.1 to 0.2 mm and is co-extruded with the frameless door sealing strip. The modified plastic layer with a thickness of 0.1 to 0.2 mm can ensure the anti-wear performance of the anti-wear layer 4 while reducing the impact on the performance of the first contact end 2 and the second contact end 3, so that the first contact end 2 and the second contact end 3 remain flexible. Compared with the traditional sprayed anti-wear coating, the one-piece anti-wear layer 4 has a lower surface friction coefficient, better anti-wear performance, and better surface flatness, which can greatly extend the service life of the sealing strip.

[0024] like Figure 1 As shown, the first contact end 2 and the second contact end 3 are both arc-shaped and protrude toward the door glass, so that the first contact end 2 and the second contact end 3 can better fit the door glass, while reducing the contact area between the first contact end 2 and the second contact end 3 and the door glass, thereby reducing friction.

[0025] like Figure 1As shown, the end of the first contact end 2 close to the B / C pillar of the vehicle body is provided with a first protrusion 201 for fitting with the side edge of the B / C pillar of the vehicle body.

[0026] In this embodiment, the first protrusion 201 is in close contact with the side of the B / C pillar of the vehicle body to provide support for the first contact end 2 and prevent the first contact end 2 from deforming at the junction with the mounting end 1 .

[0027] like Figure 1 As shown, a second protrusion 301 for contacting the side of the B / C pillar of the vehicle body is provided on a side of the second contact end 3 close to the interior of the vehicle body.

[0028] In this embodiment, the second protrusion 301 is also closely attached to the side of the B / C pillar of the vehicle body, so as to support the second contact end 3 and prevent deformation of the junction between the second contact end 3 and the mounting end 1 .

[0029] like Figure 1 As shown, a mounting groove 5 for accommodating the mounting end of the sealing strip is opened on the side of the B / C pillar of the vehicle body. The mounting end 1 of the vehicle body B / C is fixed in the mounting groove 5 by the friction force generated by the side protruding teeth 6 squeezing against the inner wall of the mounting groove 5, and the side of the protruding teeth 6 away from the mounting end 1 is inclined toward the direction of the second contact end 3.

[0030] In this embodiment, at least one convex tooth 6 is fixedly installed on the surface of the mounting end 1, and the overall width of the convex tooth 6 and the mounting end 1 is greater than the opening width of the mounting groove 5. When the mounting end 1 is inserted into the mounting groove 5, the convex tooth 6 on its surface will be squeezed and twisted, and the friction between the mounting end 1 and the mounting groove 5 is increased by the elastic force of the convex tooth 6, so as to fix the mounting end 1 in the mounting groove 5. At the same time, the convex tooth 6 is inclined toward the direction of the second contact end 3, which makes the friction force experienced by the mounting end 1 when entering the mounting groove 5 smaller than the friction force experienced by the mounting end 1 when withdrawing from the mounting groove 5, so that the resistance encountered by the mounting end 1 when entering the mounting groove 5 is smaller, and the resistance encountered by the mounting end 1 when leaving the installation is larger, thereby increasing the stability of the sealing strip after installation.

[0031] The mounting end 1 is made of hard glue, and the first contact end 2 and the second contact end 3 are both made of soft glue. The use of hard glue on the mounting end 1 can better ensure the stability of the connection between the mounting end 1 and the vehicle body B / C, and prevent the mounting end 1 from being separated from the mounting groove 5 opened on the B / C pillar of the vehicle body. The use of soft glue on the first contact end 2 and the second contact end 3 can make the first contact end 2 and the third contact 3 better fit with the vehicle door glass, thereby increasing the sealing effect.

[0032] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
