Description

Technical Field

[0001] The utility model relates to a vehicle body, in particular to a side structure on the vehicle body, wherein the side structure mainly determines the strength of the vehicle body. Background Art

[0002] The body of the car provides a relatively closed space for the car. The structure of the car body includes side structures located at intervals on both sides of the car body. Several top beams are connected between the two separated side structures. These structures play a decisive role in the strength of the car body. The side structure of the car body mainly includes side support beams. The outer surface of the side support beams is also covered and connected with exterior trims, which play a decorative role on the outer side of the side support beams.

[0003] In addition to the recessed holes for cooperating with the clip-on structure on the exterior panel, the existing side support beams do not have any special sealing measures. The sealing effect of the exterior panel on the main support beam cannot be guaranteed. Rainwater from the outside can easily penetrate into the side of the main support beam. The penetrated rainwater can flow unrestricted on the main support beam. Rainwater can easily accumulate at relatively rough welds, thereby eroding the welds. This will affect the strength of the vehicle body and bring hidden dangers to driving safety. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a vehicle body side structure, which is not easily eroded by the accumulation of external rainwater, and the strength of the vehicle body after long-term use can be guaranteed.

[0005] In order to solve the technical problem, the technical solution of the utility model is: a vehicle body side structure, including a side support beam, the side support beam includes an A-pillar beam and a top beam, and the outer side of the side support beam is covered with an exterior trim panel, characterized in that a guide groove is provided on the outer side of the side support beam, the guide groove extends along the length direction of the side support beam, the guide groove is recessed toward the back side of the side support beam, and the guide groove is open at one end at the A-pillar beam.

[0006] The side support beam is generally a stamped part, and the guide groove is generally formed simultaneously during the preparation of the side support beam. During use, a small amount of rainwater sometimes seeps between the exterior trim and the side support beam, and the rainwater will gather in the guide groove. The guide groove is used to guide the rainwater, and the inner bottom surface of the guide groove can be painted to ensure the diversion effect of the rainwater. The rainwater will flow out from the A-pillar beam to the outside, and will not accumulate on the side of the side support beam.

[0007] Furthermore, the guide groove is equal in length to the side support beam, so that the guide groove extends along the entire length direction of the side support beam, and rainwater at various locations of the side support beam can be effectively gathered in the length direction of the side support beam, thereby avoiding blind spots and providing effective protection for the side support beam.

[0008] Furthermore, there are two guide grooves, which are arranged in parallel on the side support beam. By setting the two guide grooves, two sealing lines can be provided for the side support beam, so that the sealing effect in the width direction of the side support beam can be guaranteed, so as to prevent rainwater from passing over the side support beam in the width direction and entering the vehicle body, thereby improving the anti-rainwater leakage effect of the vehicle body.

[0009] Furthermore, a mounting rib is formed between the two guide grooves on the side support beam, a plurality of connection ports are provided on the mounting rib, and a plurality of plugs are correspondingly provided on the back of the exterior panel, and one plug is plugged into one connection port. The exterior panel can be mounted on the mounting rib, which can make good use of the existing structure, has a simple structure, and is convenient for installing the exterior panel in place.

[0010] Furthermore, a notch is provided at a position corresponding to the connection port on the side mounting beam, and the notch and the corresponding connection port have corresponding dimensions in the length direction of the side support beam. The presence of the notch forms a gap at the position of the corresponding connection port on the side mounting beam, thereby facilitating the flat insertion of the plug into the corresponding connection port, and facilitating the installation and fixing of the exterior panel on the side support beam.

[0011] Furthermore, the installation rib is hollow, which makes the overall preparation of the side support beam convenient and quick, and the hollow installation rib can also effectively save material.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the guide groove is formed on the side support beam, and the guide groove is recessed toward the back side of the side support beam, so that the side support beam is curved as a whole, which can effectively increase the strength of the side support beam and save the material of the side support beam. By forming the guide groove, rainwater infiltrating from the gap between the exterior panel and the side support beam can be collected, and the infiltrated rainwater can be guided to the outside from the position of the guide groove, so that the erosion of the side support beam by rainwater can be effectively avoided, so that the strength of the vehicle body will not be damaged. Since rainwater is not easy to accumulate on the side support beam, the sealing requirements for the exterior panel on the side support beam are low, which also facilitates the installation and fixation of the exterior panel on the side support beam.

[0020] In conjunction with the drawings in the specification, the side structure of the vehicle body is located on the left and right sides of the vehicle body, playing a supporting role in the strength of the vehicle body. Figure 1 The figure shows a part of the structure of the vehicle body, wherein the windshield 1 is located at the front side of the vehicle body; the plate-type roof 5 is located at the top of the vehicle body, the front side of the roof 5 is the roof glass 4, and the driver and the passenger seats are located below the roof glass 4. The main structure of this side structure is a strip-shaped side support beam, wherein, based on the usual orientation of the vehicle, the front side of the side support beam is the A-pillar beam 3, and the middle position is the side beam 2, and the side beam 2 is arranged corresponding to the position of the roof 5 and the roof glass 4. Figure 1 As shown in the figure, the A-pillar beam 3 is located outside the front windshield 1 of the vehicle body. The body of a vehicle includes two side support beams arranged in parallel, and several top beams 6 are arranged between the two side support beams at the position of the side beams 2. The top beams 6 are transversely bridged at the positions of the two side beams 2, and the two side support beams are connected into an integral structure, which determines the strength of the vehicle body.

[0021] A flow guiding groove 33 is formed on the outer side surface of the side support beam, and the flow guiding groove 33 is recessed towards the back side of the side support beam. The flow guiding groove 33 extends along the length direction of the side support beam, and normally, the flow guiding groove 33 is as long as the side support beam. The flow guiding groove 33 is open at the position of the A-pillar beam 3, and the rainwater entering the flow guiding groove 33 will flow out to the outside at the A-pillar beam 3 along the flow guiding groove 33. There are two flow guiding grooves 33, and the two flow guiding grooves 33 are arranged side by side at intervals on the side support beam. An installation rib 31 is formed between the two flow guiding grooves 33. The installation rib 31 separates the two flow guiding grooves 33. The installation rib 31 extends along the length direction of the side support beam, and the installation rib 31 is also as long as the side support beam. The installation rib 31 and the flow guiding groove 33 are integrally formed during the stamping preparation process of the side support beam. The installation rib 33 is hollow, and the cross section of the installation rib 33 is in the shape of "冂".

[0022] An exterior trim panel 7 is also provided on the outer side surface of the side support beam. The exterior trim panel 7 is adapted to the length of the side support beam. The outer contour of the exterior trim panel 7 is similar to the overall outer contour shape of the side support beam. The exterior trim panel 7 covers the outer side surface of the side support beam to play a decorative role for the side support beam.

[0023] Connection interfaces 32 are provided on the installation rib 31. There are multiple connection interfaces 32, and these connection interfaces 32 are arranged at intervals along the length direction of the side support beam. Among them, two adjacent connection interfaces 32 form a pair. The interval distance between different pairs of connection interfaces 32 in the length direction of the installation rib 31 is relatively large, and usually several pairs of connection interfaces 32 are provided on the installation rib 31. For the two connection interfaces 32 in a pair of connection interfaces 32, their positions are required to be staggered with each other in the circumferential direction of the installation rib 31. Corresponding to the connection interfaces 32, a number of plugs are provided on the back surface of the exterior trim panel 7. The plugs and the positions of the connection interfaces 32 correspond one by one, and one plug is inserted into one connection interface 32. The connection interfaces 32 correspond to the sizes of the inserted plugs. This size refers to the size in the length direction of the installation rib 31. The size of the connection interfaces 32 in this direction should be slightly larger than or equal to the size of the plugs. In the width direction of the installation rib 31, the size of the connection interfaces 32 should be slightly larger than the size of the plugs. Corresponding to the connection interfaces 32 arranged in pairs, the plugs are also arranged in pairs. Among a pair of plugs, one plug is a flat plug 72, and the other plug is a folded plug 71. The flat plug 72 is in a straight plate shape, and the folded plug 71 is in an L shape. A number of sheet-shaped reinforcing pieces 73 are integrally formed between the flat plug 72 and the folded plug 71 and the inner surface of the exterior trim panel 7 respectively. The reinforcing pieces 73 on the same plug are arranged side by side at intervals. When the cross section of the installation rib 31 is in the shape of "冂", the two connection interfaces 32 in a pair of connection interfaces 32 are respectively located on the adjacent side surface and the surface of the installation rib 31.

[0024] See Figure 3To facilitate the insertion of the folding plug 71, a notch 34 is provided on the inner side of the side support beam at a position corresponding to the connection port 32 on the side of the mounting rib 31. The folding plug 71 can be conveniently inserted into the connection port 32 on the side of the mounting rib 31 from the position of the notch 34.

[0025] The plugs are offset on the outer trim panel 7 , and are arranged toward one side in the width direction of the outer trim panel 7 . More specifically, when the outer trim panel 7 is mounted on the side support beam, the plugs are offset toward the outer side of the vehicle on the outer trim panel 7 .

[0026] Taking the installation of the exterior trim panel 7 on the A-pillar beam 3 as an example, when installing the exterior trim panel 7 on the A-pillar beam 3, first insert the folding plug 71 into the connection port 32 on the side of the mounting rib 31 accordingly. After being inserted into place, press the exterior trim panel 7 toward the A-pillar beam 3 on the side facing the front end of the vehicle, so that the flat plug 72 is inserted into the corresponding connection port 32 on the upper surface of the mounting rib 31, and the folding plug 71 continues to penetrate into the inner side of the mounting rib 31, thereby ensuring that the exterior trim panel 7 is firmly installed on the outer side of the A-pillar beam 3.
