[0031] Example 1

[0032] This embodiment provides a plastic top edge beam mounting structure, such as Figures 2-4 As shown, the system includes a plastic top edge beam, a roof sheet 1, a vehicle side panel 2, and a vehicle roof cover edge beam 3. One side of the plastic top edge beam is the roof assembly side, used for assembly with the roof sheet 1. The roof sheet 1 has at least one first snap-fit ​​piece 4 on the side used for assembly with the plastic top edge beam. Correspondingly, the plastic top edge beam has a first snap-fit ​​hole 5 on the roof assembly side that matches the first snap-fit ​​piece 4. The plastic top edge beam is snapped and fixed to the roof sheet 1 on the roof assembly side through the first snap-fit ​​hole 5 and the first snap-fit ​​piece 4. The other side of the plastic top edge beam is the side panel assembly side, which has a snap-fit ​​piece 6. The snap-fit ​​piece 6 has at least one second snap-fit ​​hole. Correspondingly, the vehicle side panel 2 has a second snap-fit ​​piece 7 that matches the second snap-fit ​​hole. The side panel assembly side of the plastic top edge beam is snapped and fixed to the vehicle side panel 2 through the second snap-fit ​​hole and the second snap-fit ​​piece 7, thus realizing the double-sided snap-fit ​​fixing of the plastic top edge beam and thereby realizing the installation of the plastic top edge beam.

[0033] The following is a detailed description of the installation structure of the plastic top edge beam:

[0034] The plastic top edge beam is fixed by double-sided snap-fit, requiring high local resilience during installation to accommodate bending deformation. Therefore, the plastic top edge beam is made of PP and EPDM composite materials, such as 10% MF EPDM rubber composite PP automotive material, or it can be made of PDCPD material. Those skilled in the art can choose according to actual needs.

[0035] The plastic top edge beam is integrally molded and is set on the outside of the roof edge beam of the vehicle body. It includes a first edge beam part 8, and a second edge beam part 9 and a third edge beam part 10 are respectively vertically arranged at both ends of the first edge beam part 8. The second edge beam part 9 is used to cooperate with the roof sheet 1, and the inner side of the third edge beam part 10 is used to cooperate with the side panel 2 of the vehicle body, and the outer side is positioned to cooperate with the door.

[0036] The bottom end of the first side beam 8 is provided with a bent part, which fits against the top surface of the vehicle roof side beam 3. The bent part has an upward protruding part, and a snap-fit ​​cavity 11 is formed between the upward protruding part and the top surface of the vehicle roof side beam.

[0037] The snap-fit ​​cavity 11 is provided with at least one first snap-fit ​​hole 5 on the side facing the roof sheet metal 1. In order to ensure the snap-fit ​​is firm, multiple first snap-fit ​​holes 5 are provided. The number of first snap-fit ​​holes 5 can be 6 or 8, etc., and this embodiment does not limit it.

[0038] Correspondingly, the side of the roof panel 1 used for cooperating with the plastic roof side beam is provided with a first clamping piece 4 matched with the first clamping hole.

[0039] The first clamping piece 4 is a flexible metal sheet, which cannot be integrally formed with the roof panel, and thus the first clamping piece is fixed to the roof panel by welding.

[0040] The first clamping piece 4 is a flexible metal sheet, which can be deformed and reset, facilitating clamping and fixing with the plastic roof side beam.

[0041] The first clamping piece 4 is inserted into the clamping cavity 11 through the first clamping hole 5, so as to realize clamping and fixing of the plastic roof side beam with the roof panel 1 on the roof cover assembly side.

[0042] The first clamping piece 4 is provided with a first protruding structure 12 protruding upward, and in the process of inserting the first clamping piece 4 into the clamping cavity 3, the first protruding structure 12 is extruded and deformed, and after passing through the first clamping hole 5, the shape is restored and embedded into the clamping cavity 11, so as to realize clamping and fixing of the first clamping piece 4 with the plastic roof side beam.

[0043] The first protruding structure 12 is a pointed structure or a circular arc structure or a trapezoidal protruding structure protruding upward, and when the pointed structure is used, stress concentration is easy to occur at the sharp corner, affecting the service life, and it is not easy to produce extrusion deformation, so in the embodiment, the first protruding structure 12 is a circular arc structure or a trapezoidal protruding structure protruding upward, and preferably a circular arc structure.

[0044] Based on the above structure, when the plastic roof side beam is pushed towards the roof panel, the first clamping piece 4 is inserted into the clamping cavity 11 through the first clamping hole 5, and the circular arc first protruding structure is extruded and flattened when passing through the first clamping hole, and after passing through the first clamping hole, the shape is restored and embedded in the clamping cavity, realizing clamping and fixing of the plastic roof side beam with the roof panel 1.

[0045] The third side beam part 10 is used for clamping and fixing with the body side wall 2 as the side assembly side, and in the embodiment, the third side beam part 10 is a bent plate structure, and the bottom end has a bend which is attached to the outer side of the body side wall 2.

[0046] The third side beam part 10 is used for clamping and fixing with the body side wall 2 as the side assembly side, and in the embodiment, the third side beam part 10 is a bent plate structure, and the bottom end has a bend which is attached to the outer side of the body side wall 2.

[0047] The clamping piece 6 is a hollow structure with a cavity inside, which serves as a clamping cavity. Since the plastic top beam cannot be welded and fixed with the clamping piece 6, the clamping piece 6 is also made of plastic material and is fixed to the inner side of the third beam part 10 by bonding.

[0048] Further, the clamping piece 6 adopts a rectangular tube structure or a square tube structure or a cylindrical tube structure. In order to ensure the bonding firmness of the inner side of the third beam part 10, the clamping piece 6 adopts a rectangular tube structure or a square tube structure, preferably a rectangular tube structure with a rectangular cross section and a cavity inside as a clamping cavity.

[0049] The clamping piece 6 is provided with at least one second clamping hole 13 on the pipe wall of the body side wall. In order to improve the firmness of the clamping, a plurality of second clamping holes 13 are provided. The number of second clamping holes 13 can be 6 or 8, etc., which is not limited in the embodiment.

[0050] Correspondingly, the body side wall 2 is provided with a second clamping piece 7 matched with the second clamping hole 13.

[0051] The second clamping piece 7 is a flexible metal sheet that can be deformed and restored. One end of the second clamping piece 7 is used to insert into the internal cavity of the clamping piece 6, and the other end is provided with a flange and is welded and fixed to the body side wall 2 through the flange.

[0052] The second clamping piece 7 is provided with a second protruding structure 14 protruding upward. During the process of inserting the second clamping piece 7 into the internal cavity of the clamping piece 6, the second protruding structure 14 is extruded and deformed, and the shape is restored after passing through the second clamping hole 13 and is embedded in the internal cavity of the clamping piece 6, thereby realizing the clamping and fixing of the second clamping piece 7 and the plastic top beam.

[0053] The second protruding structure 14 adopts a sharp structure or a circular arc structure or a trapezoidal structure protruding upward. When a sharp structure is adopted, stress concentration is easy to occur at the sharp corner, affecting the service life, and it is not easy to produce extrusion deformation. Therefore, in the embodiment, the second protruding structure 14 adopts a circular arc structure or a trapezoidal structure protruding upward, preferably a circular arc structure protruding upward.

[0054] Based on the above structure, when the plastic top beam is pressed towards the body side wall during the assembly of the side wall of the plastic top beam, the second clamping piece 7 is inserted into the internal cavity of the clamping piece 6 through the second clamping hole 13, the second protruding structure 14 is extruded and flattened when passing through the second clamping hole 13, and the shape is restored and embedded in the internal cavity of the clamping piece 6 after passing through the second clamping hole 13, thereby realizing the clamping and fixing of the plastic top beam and the body side wall 2.

[0055] The double-side clamping fixation of the plastic roof side beam through the roof assembly side and the side assembly side is more stable than the traditional plastic roof side beam fixed by a row of buckles, and the clamping position is not prone to loosening, and the entire plastic roof side beam will not shake.

[0056] Since the plastic roof side beam cannot be welded and fixed with the roof side beam of the vehicle body, the first side beam part of the plastic roof side beam has a certain space with the roof side beam of the vehicle body, and the space is filled with the flexible sealing block 15, that is, the inner side surface of the first side beam part 8 and the top surface of the roof side beam 3 of the vehicle body are provided with the flexible sealing block 15.

[0057] The flexible sealing block 15 is made of foamed glue, sponge or rubber material, preferably foamed glue, has a certain flexibility and can be deformed without hindering the installation of the plastic roof side beam.

[0058] Through the arrangement of the flexible sealing block 15, the space between the plastic roof side beam and the roof side beam of the vehicle body can be filled, avoiding abnormal noise caused by the excessive space between the plastic roof side beam and the roof side beam of the vehicle body during driving, and at the same time, the waterproof effect is achieved to prevent water from flowing to the door sealing strip and causing water leakage.

[0059] Further, the surface of the flexible sealing block 15 used for cooperating with the inner side surface of the first side beam part 8 is provided with a plurality of protrusions 16, and the protrusions 16 are in contact with the inner side surface of the first side beam part 8.

[0060] In this way, the contact between the flexible sealing block 15 and the inner side surface of the first side beam part 8 is changed from a surface contact to a plurality of point contacts, the contact area between the flexible sealing block 15 and the inner side surface of the first side beam part 8 is reduced, the flexible sealing block is more easily deformed, and the installation of the plastic roof side beam is further facilitated.

[0061] Embodiment 2

[0062] The embodiment provides an installation method of the plastic roof side beam installation structure of embodiment 1, comprising the following steps:

[0063] The flexible sealing block 15 is installed on the top surface of the roof side beam 3 of the vehicle body, and then the plastic roof side beam is placed so that the first side beam part of the plastic roof side beam is attached to the plurality of protrusions 16 of the flexible sealing block.

[0064] The installation personnel use the auxiliary ladder to operate, push the plastic roof side beam towards the roof panel 1, so that the first clamping piece 4 is inserted into the clamping cavity 11 after passing through the first clamping hole 5, and the first protrusion structure 12 is embedded in the clamping cavity 11, thereby realizing the clamping fixation of the roof assembly side of the plastic roof side beam and the roof panel 1.

[0065] The side wall assembly side of the plastic roof side beam is pressed downward, the second clamping piece 7 is inserted into the internal cavity of the clamping piece 6 after passing through the second clamping hole 13, and the second protruding structure 14 is embedded in the internal cavity of the clamping piece 6, thereby achieving the clamping and fixing of the side wall assembly side of the plastic roof side beam and the side wall 2 of the vehicle body. If the plastic roof side beam does not shake after repeated knocking, the installation and fixing of the entire plastic roof side beam is completed.

[0066] Further, a rubber hammer is used for knocking to avoid damage to the plastic roof side beam.
