Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a door ring structure and a vehicle. Background Technology

[0002] When the body-in-white arrives at the final assembly line, it needs to be positioned and transported using an assembly fixture. Current assembly fixtures typically have multiple positioning surfaces and pins. These surfaces and pins are used to locate the body positioning holes and to support the body. However, installing body positioning holes on the vehicle body may present the following technical challenges: Vehicle body positioning holes are typically located on the door sill beam, such as... Figure 6 As shown, to facilitate draft molding, the lower side plate 402 of the sill beam 4 is typically an inclined plate. The angles between the lower side plate 402 and the outer side plate 401, and between the lower side plate 402 and the lower flange 403, are not 90 degrees. If the body positioning holes are arranged on the inclined lower side plate 402, it is difficult to meet the positioning and support requirements of the body-in-white. If the draft angle of the lower side plate 402 is set to 90°, making the angle between the lower side plate 402 and the outer side plate 401 of the sill beam 4 90°, due to this small draft angle, the material flow at the lower side plate 402 is rapid during the sill beam forming process, which can easily cause quality problems such as part cracking.

[0003] Especially for one-piece door rings, the draft angle of the lower side plate of the sill beam is usually 110°, which is difficult to meet the positioning and support requirements of the body-in-white. If the draft angle of the lower side plate of the sill beam of the one-piece door ring is set to 90°, cracking and other quality problems are more likely to occur during the molding process of the one-piece door ring. Utility Model Content

[0004] The purpose of this invention is to provide a door ring structure and vehicle to alleviate or eliminate at least one of the aforementioned technical problems.

[0005] The present invention discloses a door ring structure, comprising a sill beam and a mounting bracket. The sill beam includes an outer sill beam plate, an upper sill beam plate extending from the upper edge of the outer sill beam plate toward the inward direction, a lower sill beam plate extending from the lower edge of the outer sill beam plate toward the inward direction, and a lower flange extending from the inward edge of the lower sill beam plate. The mounting bracket includes a lower bracket plate spaced below the lower sill beam plate, an outer bracket plate extending upward from the outer edge of the lower bracket plate, and a first overlapping edge extending downward from the inward edge of the lower bracket plate. The first overlapping edge overlaps the lower flange of the sill beam, the outer bracket plate overlaps the outer sill beam plate, and the lower bracket plate has a positioning hole suitable for engaging with a positioning pin of a clamp.

[0006] Optionally, the lower side plate of the bracket is provided with a gripper mounting surface, and the positioning hole is provided at the gripper mounting surface.

[0007] Optionally, the mounting surface of the gripper is horizontal.

[0008] Optionally, the mounting bracket further includes a front side plate and a rear side plate. The front side plate, the rear side plate, the lower side plate, and the outer side plate are connected to form a shell-like structure with an opening on the upper side and the inner side of the vehicle. The edge of the front side plate near the sill beam is connected to a second overlapping edge that overlaps the sill beam. The edge of the rear side plate near the sill beam is connected to a third overlapping edge that overlaps the sill beam.

[0009] Optionally, the mounting bracket and the sill beam form a cavity, and the sill beam has a leakage hole communicating with the cavity.

Detailed Implementation

[0018] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0019] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0020] like Figure 1 and Figure 2The door ring structure shown includes a sill beam portion 1 and a mounting bracket 2. The sill beam portion 1 includes an outer sill beam plate 101, an upper sill beam plate extending from the upper edge of the outer sill beam plate 101 toward the inward direction, a lower sill beam plate 102 extending from the lower edge of the outer sill beam plate 101 toward the inward direction, and a lower flange 103 extending from the inward edge of the lower sill beam plate 102. The mounting bracket 2 includes components spaced apart from the lower sill beam plate 101. The bracket has a lower side plate 201, an outer side plate 203 that extends upward from the outer edge of the lower side plate 201, and a first overlapping edge 202 that extends downward from the inner edge of the lower side plate 201. The first overlapping edge 202 overlaps with the lower flange 103 of the sill beam. The fourth overlapping edge 204 on the upper part of the outer side plate 203 overlaps with the outer side plate 101 of the sill beam. The lower side plate 201 is provided with a positioning hole 210 suitable for cooperating with the positioning pin 303 on the clamp 3.

[0021] By adopting the above technical solution, the mounting surface of the door latch is disassembled, and a mounting bracket 2 is added to the door sill beam 1. The mounting bracket 2 provides the mounting surface for the door latch 3 and provides a positioning mounting point for the door latch 3. By setting the mounting bracket 2, the requirement for the draft angle of the lower side plate 102 of the door sill beam is eliminated, which helps to reduce the manufacturing difficulty of the door sill beam 1 and the door ring structure.

[0022] like Figure 4 and Figure 5 As shown, during the final assembly of the body-in-white, the mounting surface of the clamp is supported on the support surface 302 of the clamp 3 support member 301, and the positioning pin 303 of the clamp 3 cooperates with the positioning hole 210.

[0023] As a specific example, a clamp mounting surface is provided on the lower surface of the lower side plate 201 of the bracket, and a positioning hole 210 is provided at the clamp mounting surface.

[0024] In some embodiments, the mounting surface of the clamp is horizontally positioned. A horizontally positioned mounting surface provides better downward support to the support surface 302 of the clamp 3 support member 301, thus better meeting the positioning and support requirements of the body-in-white. In a specific implementation, the clamp mounting surface is positioned downwards and perpendicular to the outer side plate 101 of the sill beam, ensuring that the clamp mounting surface is horizontally positioned.

[0025] In some embodiments, the mounting bracket 2 further includes a front side plate 205 and a rear side plate 206. The front side plate 205, rear side plate 206, lower side plate 201, and outer side plate 203 are connected to form a shell-like structure with openings on the upper and inner sides of the vehicle. The edge of the front side plate 205 near the sill beam 1 is connected to a second overlapping edge 207 that overlaps the sill beam 1. The edge of the rear side plate 206 near the sill beam 1 is connected to a third overlapping edge 208 that overlaps the sill beam 1. The shell-like mounting bracket 2 has stronger structural performance, and the shell-like structure connected to the sill beam 1 forms a cavity-reinforced structure, which can better meet the requirements for supporting the body-in-white.

[0026] In some embodiments, such as Figure 3 As shown, the mounting bracket 2 and the sill beam 1 form a cavity, and the sill beam 1 has a leakage hole 105 communicating with the cavity. The cavity of the reinforced structure is at risk of liquid accumulation; the leakage hole 105 reduces this risk. In practice, the leakage hole 105 should be located at the lowest point of the cavity.

[0027] In some embodiments, the outer side plate 203 of the bracket is provided with an exhaust rib 209 that arches outward towards the outside of the vehicle, and an exhaust channel is formed between the exhaust rib 209 and the sill beam portion 1. The formation of the exhaust channel helps to ensure the quality of electrophoresis.

[0028] In some embodiments, a clearance hole 104 is provided on the lower side plate 102 of the sill beam to avoid the positioning pin 303, thereby preventing the positioning pin 303 from interfering with the sill beam 1.

[0029] In some embodiments, the mounting bracket 2 is a one-piece molded sheet metal part, which is easy to implement. In specific implementations, since the mounting bracket 2 needs to support the weight of the body-in-white, it is preferable to manufacture the mounting bracket 2 with a high-strength sheet of 2mm or more.

[0030] In some embodiments, the door ring structure includes an integral door ring body, which includes a threshold beam portion 1.

[0031] In practice, the mounting bracket 2 can be fixedly connected to the sill beam 1 by welding, for example, each overlapping edge can be welded to the sill beam 1.

[0032] In some embodiments, the present invention also provides a vehicle including the door ring structure described in any of the preceding claims.

[0033] Vehicles can be, but are not limited to, pure electric vehicles (PEV / BEV), hybrid electric vehicles (HEV), range-extended electric vehicles (REEV), plug-in hybrid electric vehicles (PHEV), new energy vehicles, and gasoline vehicles.
