Technical Field

[0001] This utility model relates to the field of automotive technology, specifically to a connection structure for seat crossbeams and sill beams, and a vehicle thereof. Background Technology

[0002] When a vehicle is involved in a side collision or severe operating conditions, the connecting bracket between the front seat crossbeam and the aluminum sill beam is prone to deformation and failure, which can lead to tearing at the bolts. This can cause the entire seat crossbeam to puncture the aluminum sill beam, and the deformation caused by the huge side impact force can cause the aluminum sill beam to intrude into the passenger compartment, threatening the safety of the occupants. Utility Model Content

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: The first aspect of this utility model protects a connection structure for a seat crossbeam and a sill beam, comprising a seat crossbeam body, a sill beam body, a first connector, and a second connector; The end of the seat beam body is fixedly connected to the sill beam body through the first connector; The second connector includes a horizontal connecting section and a vertical connecting section; the horizontal connecting section is fixed to the upper end face of the seat beam body and is located between the seat beam body and the first connector; the vertical connecting section is fixed between the seat beam body and the sill beam body. As a further technical solution At least two spaced recesses are provided along the length of the vertical connecting section, and the openings of the recesses face the sill beam body.

[0005] As a further technical solution, a pad is also included, which is disposed in the recess.

[0006] As a further technical solution, the first connector includes a first mounting section and a second mounting section; The first mounting section is connected to the second mounting section, and the first mounting section is adapted to be fixed to the upper wall of the sill beam body, while the second mounting section is adapted to be fixed to the upper wall of the transverse connecting section.

[0007] As a further technical solution, the first connector also includes a third mounting section and a fourth mounting section; The second mounting section is perpendicularly connected to both ends along its length, and the cross-sectional structure enclosed by the second mounting section and the third mounting section is n-shaped.

Detailed Implementation

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0017] In the description of this application, the term "for example" is used to mean "used as an example, illustration, or description." Any embodiment described as "for example" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0018] Example 1 See Figures 1-3 , Figure 5This embodiment provides a connection structure for a seat crossbeam and a sill beam, including a seat crossbeam body 1, a sill beam body 2, a first connector 3, and a second connector 4; the end of the seat crossbeam body 1 is fixedly connected to the sill beam body 2 through the first connector 3; the second connector 4 includes a horizontal connecting section 41 and a vertical connecting section 42; the horizontal connecting section 41 is fixed to the upper end face of the seat crossbeam body 1 and is located between the seat crossbeam body 1 and the first connector 3; the vertical connecting section 42 is fixed between the seat crossbeam body 1 and the sill beam body 2.

[0019] That is, in this embodiment, the seat crossbeam body 1 and the sill beam body 2 are connected simultaneously by the first connector 3 and the second connector 4, realizing a double connector connection, which improves the connection strength between the two. At the same time, it prevents the sill beam body 2 from puncturing into the seat crossbeam body 1 when a side collision occurs, avoiding direct contact between the seat crossbeam body 1 and the sill beam body 2, improving the consumption of side collision force during transmission, and also preventing the sill beam body 2 from intruding into the vehicle body, thus improving the safety factor in the passenger compartment.

[0020] For example, the second connector 4 is made of duplex high-strength steel with a yield strength of not less than 330 MPa and a tensile strength of not less than or equal to 590 MPa. The sill beam body 2 is made of aluminum alloy. The thickness of the second connector 4 is greater than or equal to 2 mm, and the second connector 4 is a sheet metal part.

[0021] For example, the first connector 3 is fixed to the seat crossbeam body 1 and the sill beam body 2 by bolts.

[0022] See Figure 3 , Figure 4 In the specific implementation process, at least two spaced recesses 421 are provided along the length direction of the vertical connecting section 42, and the openings of the recesses 421 face the threshold beam body 2.

[0023] It should be noted that the vertical connecting section 42 is connected to the sill beam body 2 via FDS (i.e., hot melt self-tapping screw connection). The horizontal connecting section 41 is connected to the first connecting member 3 by welding to obtain high strength and rigidity.

[0024] It should be noted that the threaded hole on the transverse connecting section 41 is concentric with the threaded hole on the first connecting member 3.

[0025] It should be noted that in this embodiment, the area where the first connector 3 is connected to the seat beam body 1 is the stress area, that is, the stress area of ​​the seat beam body 1 is located on its top surface. Therefore, the design of the vertical connecting section 42 improves the rigidity and strength of the stress area.

[0026] See Figures 2-5 In the specific implementation process, a pad 5 is also included. The pad 5 is disposed in the recess 421. At this time, due to the design of the recess 421, there is a gap between the side wall of the sill beam body 2 and the end of the seat crossbeam body 1. When there is a side collision, the seat crossbeam body 1 first contacts the opposite side of the vertical connecting section 42 with the recess 421 to abut against the seat crossbeam body 1, thereby avoiding direct contact between the seat crossbeam body 1 and the sill beam body 2. That is, the gap at this time can be a buffer zone.

[0027] For example, the pad 5 has a thickness of 5mm, which effectively prevents the seat crossbeam body 1 from contacting the sill beam body 2 and prevents the seat crossbeam body 1 from puncturing the sill beam body 2. In addition, it improves the energy absorption effect of the overall structure.

[0028] For example, the cross-sectional shape of the recessed portion 421 is shaped like a π to improve the energy absorption effect of the second connector 4.

[0029] See Figure 1 , Figure 4 , Figure 5 In the specific implementation process, the first connecting member 3 includes a first mounting section 31 and a second mounting section 32; the first mounting section 31 is connected to the second mounting section 32, and the first mounting section 31 is adapted to be fixed to the upper wall of the threshold beam body 2, and the second mounting section 32 is adapted to be fixed to the upper wall of the transverse connecting section 41.

[0030] It should be noted that the screw holes on the second mounting section 32 and the transverse connecting section 41 are concentric, that is, the second mounting section 32 and the transverse connecting section 41 are fixed to the top of the seat beam body 1 by screws.

[0031] For example, the first mounting section 31 is fixed to the sill beam body 2 by screws.

[0032] Furthermore, the first connector 3 also includes a third mounting section 33 and a fourth mounting section 34; both ends of the second mounting section 32 are vertically connected to the third mounting section 33, and the cross-sectional structure enclosed by the second mounting section 32 and the third mounting section 33 is n-shaped to achieve three-sided wrapping of the seat beam body 1, thereby strengthening the connection strength of the seat beam body 1 and improving the load-bearing capacity of the second mounting section 32; the fourth mounting section 34 is connected to the side of the third mounting section 33 closest to the sill beam body 2, and one third mounting section 33 corresponds to one fourth mounting section 34. The fourth mounting section 34 is fixedly connected to the sill beam body 2 through the vertical connecting section 42, thereby strengthening the connection strength between the seat beam body 1 and the sill beam body 2.

[0033] It should be noted that the cross-sectional structure formed by the fourth mounting section 34 and the third mounting section 33 is type 7.

[0034] It should be noted that the fourth mounting section 34 and the vertical connecting section 42 are connected to the sill beam body 2 by screws.

[0035] Furthermore, extension sections 422 are provided at both ends along the length of the vertical connecting section 42, and the fourth mounting section 34 is fixedly connected to the sill beam body 2 through the extension sections 422. That is, the length of the vertical connecting section 42 is greater than or equal to the total length of the second mounting section 32 and the third mounting section 33, which facilitates disassembly and assembly.

[0036] This embodiment has a simple structure and is easy to operate, and at least improves the overall strength and rigidity of the structure, as well as the safety of the crew cabin.

[0037] Example 2 This embodiment provides a vehicle including a connection structure for the seat crossbeam and sill beam as described in Embodiment 1. The vehicle with this connection structure improves stability and safety within the passenger compartment.
