Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, specifically to a seat mounting beam, a floor assembly, and a vehicle. Background Technology
[0002] During the development of new energy vehicles, the same model is usually configured differently according to different energy types. For example, the same model may be configured as a pure electric vehicle, a plug-in hybrid electric vehicle, and a range-extended electric vehicle. Products of different energy types will have structural differences.
[0003] The prior art discloses an electric vehicle seat mounting crossbeam, which is applied to a pure electric vehicle. The seat mounting crossbeam includes a front seat crossbeam and a front crossbeam connecting plate welded together.
[0004] Because the floor structure and assembly process of plug-in hybrid vehicles are different from those of pure electric vehicles, this seat mounting beam is not applicable to plug-in hybrid vehicles and similar models. Utility Model Content
[0005] The purpose of this utility model is to provide a seat mounting beam, a floor assembly, and a vehicle, so as to at least solve the problem that seat mounting beams are not universal in related technologies.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] According to a first aspect of this application, a seat mounting crossbeam is provided, comprising: a crossbeam body, a first connecting bracket, and a second connecting bracket. The crossbeam body is used to support a seat and is used to connect to the floor. Along the length of the crossbeam body, the first connecting bracket is detachably connected to one end of the crossbeam body, and the second connecting bracket is detachably connected to the other end of the crossbeam body. Both the first connecting bracket and the second connecting bracket are used to connect to the vehicle body.
[0008] According to the above technical means, when the seat mounting beam is applied to a pure electric vehicle, the beam body is connected to the floor, and the first connecting bracket and the second connecting bracket are connected to the vehicle body. During installation in the final assembly workshop, the beam body is lifted together with the battery pack cover (i.e., the floor) to the corresponding position of the battery pack, and then the beam body is connected to the first connecting bracket and the second connecting bracket at both ends.
[0009] When the seat mounting beam is applied to a plug-in hybrid vehicle or a range-extended electric vehicle, the beam body is connected to the floor, the first connecting bracket is connected to the left sill beam, the second connecting bracket is connected to the right sill beam, and after the beam body is installed in the corresponding position along with the floor, the floor and the vehicle body are connected, and the beam body is connected to the first and second connecting brackets at both ends.
[0010] Thus, through the overlapping action of the first and second connecting brackets, the crossbeam body will not be interfered with by the sill beam when lifted from below, and will not be unable to be connected and fixed to the sill beam when lowered from above due to the length of the crossbeam body being shorter than the distance between the sill beams. In this way, the versatility of the seat mounting crossbeam can be improved, making it applicable to pure electric vehicles, as well as traditional models, plug-in hybrid vehicles, or range-extended electric vehicles, thereby reducing the development and production costs of parts and shortening the development cycle of the whole vehicle.
[0011] In one possible implementation, the first connecting bracket includes a mating part and a connecting part. The mating part is detachably connected to the crossbeam body, and the connecting part is connected to the end of the mating part away from the crossbeam body. The connecting part is used to connect to the vehicle body.
[0012] According to the above-mentioned technical means, the first connecting bracket can enhance the flexibility of the connection between the crossbeam body and the vehicle body. When the distance between the left sill beam and the right sill beam of the vehicle body is different due to the vehicle model, the first connecting bracket can be used as a connecting bridge. By adjusting the connection position between the mating part and the crossbeam body, the crossbeam body can be fixedly connected to the sill beam without adjusting the size of the crossbeam body. Thus, the seat mounting crossbeam can be adapted to different vehicle models.
[0013] In one possible implementation, the seat mounting beam includes a first fastener, a mating part having a first mating hole, and the beam body having a second mating hole, with the fastener passing through the first and second mating holes.
[0014] According to the aforementioned technical means, the first fastener passes through the first mating hole of the mating part and the second mating hole of the crossbeam body, which can fix the mating part of the first connecting bracket to the crossbeam body. The connection via the first fastener allows for detachment between the first connecting bracket and the crossbeam body. Thus, the crossbeam body can be first connected to the floor, and then moved to the appropriate position to connect with the first connecting bracket by lifting or lowering, thereby improving the versatility of the seat mounting crossbeam.
[0015] In one possible implementation, the crossbeam body includes a mounting portion, a first support portion, and a second support portion. The mounting portion is used to connect the seat. The first support portion and the second support portion are respectively connected to the two ends of the mounting portion along the width direction of the crossbeam body. The mating portion includes a first mating portion, a second mating portion, and a third mating portion. The first mating portion is connected to the mounting portion, the second mating portion is connected to the first support portion, and the third mating portion is connected to the second support portion.
[0016] According to the aforementioned technical means, by providing a first support member and a second support member at both ends of the mounting section along the width direction of the crossbeam body, the mounting section can bear the pressure on the mounting section and transmit this pressure to the floor, thereby increasing the stability of the seat installation and enhancing the safety and reliability of the seat mounting crossbeam. Furthermore, by connecting the first mating part to the mounting section, the second mating part to the first support part, and the third mating part to the second support part, the connection between the mating part and the crossbeam body can be made more stable, further improving the reliability of the seat mounting crossbeam.
[0017] In one possible implementation, the connecting portion includes a first connecting portion and a second connecting portion. Along the width direction of the beam body, the first connecting portion is connected to one side of the mating portion, and the second connecting portion is connected to the other side of the mating portion.
[0018] According to the above technical means, the connecting part is used to connect the vehicle body. The first connecting part and the second connecting part are respectively arranged on both sides of the mating part along the width direction of the crossbeam body. The force transmitted from the crossbeam body to the vehicle body can be distributed to the first connecting part and the second connecting part, so that the vehicle body is subjected to more uniform force, preventing the connection from loosening or deforming due to uneven force, and further improving the stability of the seat mounting crossbeam.
[0019] In one possible implementation, the connecting portion is provided with a connecting hole; the seat mounting crossbeam further includes a second fastener, which passes through the connecting hole and is used to connect to the vehicle body.
[0020] According to the above-mentioned technical means, the connection between the connecting part and the vehicle body is achieved by the second fastener, so that the connecting part and the vehicle body form a rigid connection, thereby reducing the relative displacement between the seat mounting beam and the vehicle body and improving the stability of the seat mounting beam.
[0021] In one possible implementation, the seat mounting beam further includes a reinforcing member, wherein the surface of the beam body facing the floor has a recessed groove in a direction away from the floor, and the reinforcing member is disposed within the groove.
[0022] By incorporating reinforcing elements into the grooves, the load-bearing capacity of the seat mounting beam can be enhanced, effectively resisting dents or fractures caused by excessive loads, and improving the reliability and stability of the seat mounting beam.
[0023] In one possible implementation, the crossbeam body includes a mounting portion, a first support portion, and a second support portion, the first support portion and the second support portion being connected to both ends of the mounting portion along the width direction of the crossbeam body; the mounting portion, the first support portion and the second support portion enclose a groove; the reinforcing member includes a reinforcing portion, a third support portion and a fourth support portion, the third support portion and the fourth support portion being disposed at both ends of the reinforcing portion along the width direction of the crossbeam body, the reinforcing portion being connected to the mounting portion, the third support portion being connected to the first support portion, and the fourth support portion being connected to the second support portion.
[0024] According to the above-mentioned technical means, the mounting part, the first support part, and the second support part of the crossbeam body surround the groove, which can improve the load-bearing capacity of the crossbeam body by changing the cross-sectional shape. The reinforcing part, the third support part, and the fourth support part of the reinforcing member are connected to the corresponding positions of the groove of the crossbeam body, which can form another groove-shaped structure inside the groove, further improving the load-bearing capacity of the seat mounting crossbeam and preventing the seat mounting crossbeam from deforming or breaking when subjected to impact.
[0025] According to a second aspect provided in this application, a floor assembly is provided, including a floor and a seat mounting beam provided in the above embodiments, the beam body being connected to the floor.
[0026] According to a third aspect provided in this application, a vehicle is provided, including a vehicle body and a floor assembly provided in the above embodiments, wherein both a first connecting bracket and a second connecting bracket are connected to the vehicle body.
[0027] It should be noted that the technical effects brought about by the second and third aspects can be found in the technical effects brought about by the corresponding implementation methods in the first aspect, and will not be repeated here. Attached Figure Description

[0040] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0041] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0042] This application provides a vehicle that can be a hybrid vehicle, a range-extended electric vehicle, a plug-in hybrid vehicle, a pure electric vehicle, etc. The vehicle can also be an engineering vehicle, a special-purpose vehicle, etc.
[0043] The vehicle may include a body and wheels. The body is used to house passengers and goods, while the wheels are mounted underneath the body to support it and enable it to roll on the road surface to move the vehicle.
[0044] The vehicle may also include a floor assembly located at the bottom of the vehicle body and connected to the vehicle body to form a complete passenger space, which supports passengers and items.
[0045] The vehicle may also include seats, which are housed within the vehicle body and mounted on the floor assembly for the convenience of passengers.
[0046] In some embodiments, such as Figure 1 As shown, the floor assembly includes a floor 03 and a seat mounting beam 01 connected to the floor 03. The seat can be mounted on the seat mounting beam 01 to secure the seat, prevent the seat from moving or wobbling on the floor 03, and improve the stability of the seat.
[0047] In some embodiments, the vehicle body 02 includes a sill beam. When the seat mounting beam 01 is connected to the vehicle body 02, the seat mounting beam 01 is fixedly connected to the sill beam. This prevents the seat mounting beam 01 from shifting between itself and the floor 03 when the vehicle is subjected to impact or vibration, thereby further improving the stability of the seat and the safety of the vehicle.
[0048] In some vehicles provided in this application, such as pure electric vehicles, the battery pack cover has a large area, and the battery pack cover and floor 03 are combined into one, that is, the battery pack cover can serve as the floor 03. In this way, the gap between the floor 03 and the battery pack and the parts required to connect the two can be reduced, simplifying the production steps.
[0049] In the vehicles provided in these embodiments, the floor assembly, which serves as the top cover of the power battery pack, is installed with the vehicle body 02 in the final assembly workshop. That is, the seat mounting beam 01 is first connected to the floor 03 to form the floor assembly, and then lifted from below the vehicle body 02 together with the battery pack to complete the connection with the sill beam.
[0050] In other vehicles provided in this application, such as plug-in hybrid electric vehicles or range-extended electric vehicles, the battery pack occupies a small area at the bottom of the vehicle body 02 and cannot serve as the vehicle floor 03. Therefore, the floor 03 and the battery pack cover are two separate components.
[0051] In the vehicles provided in these embodiments, the floor assembly is welded to the body 02 in the welding workshop and finally installed with the battery pack in the final assembly workshop. At this time, the seat mounting beam 01 is lowered from above the floor 03, and at least a portion of the seat mounting beam 01 overlaps the sill beam and is welded to the sill beam for fixation.
[0052] Since the seat mounting beam 01 of a pure electric vehicle is lifted from bottom to top to complete the connection between the seat mounting beam 01 and the sill beam, if the length of the seat mounting beam 01 is greater than the distance between the left sill beam and the right sill beam, there will be interference between the seat mounting beam 01 and the sill beam during the lifting process, making installation impossible.
[0053] Since the seat mounting beam 01 of plug-in hybrid vehicles or range-extended electric vehicles is installed from top to bottom, and the length of the seat mounting beam 01 is greater than the distance between the left sill beam and the right sill beam, it is easy to overlap the seat mounting beam 01 on the sill beam to complete the welding between the seat mounting beam 01 and the sill beam.
[0054] In related technologies, the seat mounting beam 01 for pure electric vehicles, plug-in hybrid vehicles, and range-extended electric vehicles is not interchangeable. Typically, two sets of molds are used for separate production. This increases vehicle development and production costs and extends the development cycle.
[0055] Based on this, such as Figures 1-3 As shown, the seat mounting beam 01 provided in this embodiment includes a beam body 1, a first connecting bracket 2, and a second connecting bracket 3. The beam body 1 supports the seat and is connected to the floor 03. Along the length of the beam body 1, the first connecting bracket 2 is detachably connected to one end of the beam body 1, and the second connecting bracket 3 is detachably connected to the other end of the beam body 1. Both the first connecting bracket 2 and the second connecting bracket 3 are used to connect to the vehicle body 02.
[0056] When the seat mounting beam 01 is applied to a pure electric vehicle, the beam body 1 is connected to the floor 03, the first connecting bracket 2 is connected to the left door sill beam, and the second connecting bracket 3 is connected to the right door sill beam. During installation in the final assembly workshop, the beam body 1 is lifted together with the battery pack cover (i.e., the floor 03) to the corresponding position of the battery pack, and then the beam body 1 is connected to the first connecting bracket 2 and the second connecting bracket 3 at both ends.
[0057] When the seat mounting beam 01 is applied to a plug-in hybrid electric vehicle or a range-extended electric vehicle, the beam body 1 is connected to the floor 03, the first connecting bracket 2 is connected to the left sill beam, and the second connecting bracket 3 is connected to the right sill beam. After the beam body 1 is installed in the corresponding position along with the floor 03, the floor 03 is connected to the vehicle body 02, and the beam body 1 is connected to the first connecting bracket 2 and the second connecting bracket 3 at both ends.
[0058] In this way, through the overlapping action of the first connecting bracket 2 and the second connecting bracket 3, the crossbeam body 1 will not be interfered with by the sill beam when it is lifted from bottom to top, and will not be unable to be connected and fixed to the sill beam when it is lowered from top to bottom because the length of the crossbeam body 1 is shorter than the distance between the sill beams. In this way, the versatility of the seat mounting crossbeam 01 can be improved, so that it can be applied to pure electric vehicles, as well as traditional models, plug-in hybrid vehicles or range-extended electric vehicles, thereby reducing the development and production costs of parts and shortening the development cycle of the whole vehicle.
[0059] It should be noted that both the first connecting bracket 2 and the second connecting bracket 3 are connected to the vehicle body 02. Here, the description assumes that both the first connecting bracket 2 and the second connecting bracket 3 are connected to the sill beam. However, the first connecting bracket 2 and the second connecting bracket 3 can also be connected to other structures of the vehicle body 02, such as the support beam of the vehicle's center console. For example, the first connecting bracket 2 is connected to the left sill beam, and the second connecting bracket 3 is connected to the support beam of the center console.
[0060] In some embodiments, the first connecting bracket 2 includes a mating part 21 and a connecting part 22. The mating part 21 can be detachably connected to the crossbeam body 1, and the connecting part 22 is connected to the end of the mating part 21 away from the crossbeam body 1, and the connecting part 22 is used to connect the vehicle body 02.
[0061] To prevent interference between the crossbeam body 1 and the vehicle body 02 when it is lifted from bottom to top, the length of the crossbeam body 1 is less than the distance between the left sill beam and the right sill beam. The connecting part 22 is set at the end of the mating part 21 away from the crossbeam body 1. The mating part 21 is detachably connected to the crossbeam body 1, and the connecting part 22 is connected to the vehicle body 02. The crossbeam body 1 and the sill beam can be connected together by the first connecting bracket 2.
[0062] Thus, the first connecting bracket 2 can enhance the flexibility of the connection between the crossbeam body 1 and the sill beam. When the distance between the left sill beam and the right sill beam differs due to vehicle models, the first connecting bracket 2 can be used as a connecting bridge to allow the crossbeam body 1 to be fixedly connected to the sill beam without adjusting the size of the crossbeam body 1. This allows the seat mounting crossbeam 01 to be adapted to different vehicle models.
[0063] In some embodiments, the seat mounting crossbeam 01 includes a first fastener 4, the mating part 21 is provided with a first mating hole 214, the crossbeam body 1 is provided with a second mating hole 14, and the first fastener 4 passes through the first mating hole 214 and the second mating hole 14.
[0064] The first fastener 4 passes through the first mating hole 214 of the mating part 21 and the second mating hole 14 of the crossbeam body 1, and can fix the mating part 21 of the first connecting bracket 2 to the crossbeam body 1. Furthermore, the connection by the first fastener 4 can satisfy the requirement that the first connecting bracket 2 and the crossbeam body 1 are detachable. In this way, the crossbeam body 1 can be first connected to the floor 03, and then moved to the corresponding position to be connected to the first connecting bracket 2 by lifting or lowering.
[0065] In this way, the seat mounting beam 01 can be used in various vehicle types, such as pure electric vehicles, hybrid vehicles, or range-extended electric vehicles, thus enhancing the versatility of the seat mounting beam 01.
[0066] In addition, the corresponding arrangement of the first mating hole 214 and the second mating hole 14 enables the positioning between the crossbeam body 1 and the first connecting bracket 2, making the connection more precise and reliable.
[0067] In some embodiments, the first fastener 4 can be configured as a mating bolt, which is used to connect the crossbeam body 1 and the mating part 21 by passing the mating bolt through the first mating hole 214 and the second mating hole 14, which facilitates the connection, disassembly and maintenance of the two and reduces processing and maintenance costs.
[0068] In other embodiments, the first fastener 4 may also be a screw, rivet, or expansion clip, etc., which are not further limited in this application.
[0069] It is understandable that the mating part 21 is provided with a first mating hole 214 and the crossbeam body 1 is provided with a second mating hole 14. When the vehicle model to which the seat mounting crossbeam 01 is applicable is adjusted, the positions of the first mating hole 214 and the second mating hole 14 can be adjusted so that the connection between the first connecting bracket 2 and the crossbeam body 1 can meet the needs of vehicle models with different widths, thereby further improving the versatility of the seat mounting crossbeam 01.
[0070] like Figure 3 and Figure 4 As shown, in some embodiments, the crossbeam body 1 includes a mounting portion 11, a first support portion 12, and a second support portion 13. The mounting portion 11 is used to connect the seat. The first support portion 12 and the second support portion 13 are respectively connected to the two ends of the mounting portion 11 along the width direction of the crossbeam body 1. The mating portion 21 includes a first mating portion 211, a second mating portion 212, and a third mating portion 213. The first mating portion 211 is connected to the mounting portion 11, the second mating portion 212 is connected to the first support portion 12, and the third mating portion 213 is connected to the second support portion 13.
[0071] Mounting section 11 is used to connect the seat. To facilitate assembly and fastening between mounting section 11 and the seat, mounting section 11 is usually provided with fittings for assembling the seat, and an installation gap is left between mounting section 11 and floor 03. First support members and second support members are provided at both ends of mounting section 11 along the width direction of crossbeam body 1. These members can bear the pressure on mounting section 11 and transmit the pressure to floor 03 through first support section 12 and second support section 13, thereby increasing the stability of seat installation and enhancing the safety and reliability of seat mounting crossbeam 01.
[0072] Based on this, the mating part 21 includes a first mating part 211, a second mating part 212 and a third mating part 213. The first mating part 211 is connected to the mounting part 11, the second mating part 212 is connected to the first support part 12, and the third mating part 213 is connected to the second support part 13. In this way, the connection between the mating part 21 and the crossbeam body 1 can be made more stable, and the reliability of the seat mounting crossbeam 01 can be further improved.
[0073] In some embodiments, the first mating part 211, the second mating part 212, and the third mating part 213 are all provided with a first mating hole 214, and the mounting part 11, the first support part 12, and the second support part 13 are all provided with a second mating hole 14. In this way, the first mating part 211 can be detachably connected to the mounting part 11, the second mating part 212 can be detachably connected to the first support part 12, and the third mating part 213 can be detachably connected to the second support part 13. This allows the fastening force of the first fastener 4 to be transmitted more evenly between the beam body 1 and the first connecting bracket 2, making the connection between the beam body 1 and the first connecting bracket 2 more stable.
[0074] In some embodiments, the connecting portion 22 includes a first connecting portion 221 and a second connecting portion 222. Along the width direction of the beam body 1, the first connecting portion 221 is connected to one side of the mating portion 21, and the second connecting portion 222 is connected to the other side of the mating portion 21.
[0075] The connecting part 22 is used to connect the body 02. The first connecting part 221 and the second connecting part 222 are respectively provided on both sides of the mating part 21 along the width direction of the crossbeam body 1. The force transmitted from the crossbeam body 1 to the body 02 can be distributed to the first connecting part 221 and the second connecting part 222, so that the body 02 is subjected to more uniform force, preventing the connection from loosening or deforming due to uneven force, and further improving the stability of the seat mounting crossbeam 01.
[0076] In some embodiments, the connecting part 22 is provided with a connecting hole; the seat mounting crossbeam 01 further includes a second fastener 5, which passes through the connecting hole and is used to connect the vehicle body 02.
[0077] The second fastener 5 connects the connecting part 22 to the body 02, so that the connecting part 22 and the body 02 form a rigid connection, thereby reducing the relative displacement between the seat mounting beam 01 and the body 02 and improving the stability of the seat mounting beam 01.
[0078] In addition, the connecting part 22 is detachably connected to the body 02 through the second fastener 5. Compared with the non-detachable connection, the position between the crossbeam body 1, the first connecting bracket 2 and the body 02 can be adjusted more flexibly according to different models, thereby meeting the needs of different assembly processes of different models and saving development and maintenance costs.
[0079] For example, the second fastener 5 can be a connecting bolt, screw, expansion clip, etc., and this application does not further limit it.
[0080] In addition, by providing a connecting hole on the connecting part 22, the second fastener 5 passes through the connecting hole and connects to the body 02, which can achieve accurate positioning between the connecting part 22 and the body 02, thereby reducing the problem of beam tilting or uneven force due to connection misalignment, and further improving the stability and connection accuracy of the seat mounting beam 01.
[0081] In some embodiments, the connecting part 22 and the mating part 21 are integrally formed, which reduces the number of parts, facilitates production and assembly, and saves production costs.
[0082] The second connecting bracket 3 has the same structure as the first connecting bracket 2, and the connection method between the second connecting bracket 3 and the crossbeam body 1 is the same as the connection method between the first connecting bracket 2 and the crossbeam body 1. The specific structure and connection method of the second connecting bracket 3 will not be described in detail here.
[0083] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, the seat mounting beam 01 further includes a reinforcing member 6, and the surface of the beam body 1 facing the floor 03 is provided with a recessed groove in a direction away from the floor 03, and the reinforcing member 6 is disposed in the groove.
[0084] The crossbeam body 1 is used to directly connect with the seat and bear the weight of the seat, the weight of the driver and passengers, and the impact of vehicle bumps. The surface of the crossbeam body 1 facing the floor 03 is provided with a groove that is recessed away from the floor 03. This can improve the bending stiffness of the crossbeam body 1 by changing the cross-sectional shape of the crossbeam body 1 and reduce the possibility of bending deformation when the crossbeam body 1 is subjected to impact.
[0085] Based on this, a reinforcing member 6 is set in the groove, which can further enhance the load-bearing capacity of the seat mounting beam 01 and effectively resist dents or fractures caused by excessive load.
[0086] Setting the reinforcing member 6 in the groove can ensure the flatness of the beam body 1 when it contacts the floor 03, reduce the assembly gap, and prevent the floor 03 from deforming due to the beam protrusion.
[0087] In addition, a groove is provided on the surface of the crossbeam body 1 facing the floor 03 to allow for the assembly gap between the seat and the crossbeam body 1, which facilitates the installation and fastening of the seat and the crossbeam body 1.
[0088] In some embodiments, the beam body 1 includes a mounting portion 11, a first support portion 12, and a second support portion 13. The first support portion 12 and the second support portion 13 are connected to both ends of the mounting portion 11 along the width direction of the beam body 1. The mounting portion 11, the first support portion 12, and the second support portion 13 enclose a groove. The reinforcing member 6 includes a reinforcing portion 61, a third support portion 62, and a fourth support portion 63. The third support portion 62 and the fourth support portion 63 are disposed at both ends of the reinforcing portion 61 along the width direction of the beam body 1. The reinforcing portion 61 is connected to the mounting portion 11, the third support portion 62 is connected to the first support portion 12, and the fourth support portion 63 is connected to the second support portion 13.
[0089] The mounting portion 11, the first support portion 12, and the second support portion 13 of the crossbeam body 1 enclose a groove, which can improve the load-bearing capacity of the crossbeam body 1 by changing the cross-sectional shape. The reinforcing portion 61, the third support portion 62, and the fourth support portion 63 of the reinforcing member 6 are connected to the corresponding positions of the groove of the crossbeam body 1, which can form another groove-shaped structure inside the groove, further improving the load-bearing capacity of the seat mounting crossbeam 01 and preventing the seat mounting crossbeam 01 from deforming or breaking when subjected to impact.
[0090] In addition, the reinforcing part 61 is connected to the mounting part 11, the third support part 62 is connected to the first support part 12, and the fourth support part 63 is connected to the second support part 13. This allows the force on the crossbeam body 1 to be evenly transmitted to the reinforcing member 6 and then distributed to the body 02 and the floor 03. In this way, the transmission path can be optimized, the load distribution efficiency can be improved, and the reliability and stability of the seat mounting crossbeam 01 can be enhanced.
[0091] In some embodiments, the reinforcing member 61 is welded to the crossbeam body 1. This ensures a stable connection between the reinforcing member 6 and the crossbeam body 1, preventing loosening due to vehicle impacts or vibrations, thereby enhancing the strength of the seat mounting crossbeam 01.
[0092] In some embodiments, the length of the reinforcing member 6 is less than the length of the beam body 1 along the length direction of the beam body 1. This allows for the provision of a fitting space between the beam body 1 and the first connecting bracket 2 and the second connecting bracket 3, so that the first fastener 4 can pass through the first fitting hole 214 and the second fitting hole 14.
[0093] In some embodiments, the beam body 1 may further include a first bent edge 15 and a second bent edge 16. The first bent edge 15 is connected to the end of the first support portion 12 away from the support portion, and the second bent edge 16 is connected to the end of the second support portion 13 away from the support portion. The planes containing the first bent edge 15 and the second bent edge 16 are parallel to the plane containing the support portion.
[0094] In this way, since the beam body 1 is connected to the floor 03, the first bent edge 15 and the second bent edge 16 can increase the contact area between the beam body 1 and the floor 03, thereby making the connection between the beam body 1 and the floor 03 more stable.
[0095] In some embodiments, the first bent edge 15 and the second bent edge 16 are both fixed to the floor 03 by welding. This enhances the connection strength between the beam body 1 and the floor 03, facilitating the lifting or lowering of the beam body 1 along with the floor 03 during subsequent assembly, and preventing the beam body 1 from loosening or shifting during assembly.
[0096] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
