Description

Technical Field

[0001] This utility model relates to the technical field of automobiles, and in particular to a crossbeam assembly, a seat, and a vehicle. Background Technology

[0002] The crossbeam serves to bear longitudinal loads, provide stable support, and absorb energy during a collision. In a seat, the seat crossbeam is a transverse structure installed at the bottom of the seat, serving as a supporting and stabilizing component connecting the seat base and the seat back. When the vehicle is hit on one side, the door sill deforms, and the crossbeam can effectively support the deformed door sill, ensuring the stability of the seat.

[0003] To increase resistance to deformation, existing beams are made heavier by increasing plate thickness to ensure structural strength and stiffness, which increases the beam's weight and cost. Utility Model Content

[0004] To address the technical problem of the heavy weight of the aforementioned crossbeams increasing costs, this utility model provides a crossbeam assembly, a seat, and a vehicle.

[0005] To achieve the above objectives, the present invention provides a crossbeam assembly, including a crossbeam body, the crossbeam body including a reinforcing part and a supporting part, the supporting part being connected to both sides of the reinforcing part, the supporting part being connected to the vehicle floor, a first cavity being formed between the reinforcing part and the vehicle floor, the reinforcing part including a protrusion extending toward and / or away from the first cavity.

[0006] Furthermore, the main body of the crossbeam is made of high-strength composite material through pultrusion molding, which includes reinforcing fibers and organic resin.

[0007] Furthermore, the support includes a first support and a second support connected together. The end of the first support away from the second support is connected to the reinforcing part, and the second support is attached to the vehicle body floor. An angle is formed between the first support and the second support.

[0008] Furthermore, the crossbeam assembly also includes a reinforcing beam located within the first cavity. The reinforcing beam is connected to both the crossbeam body and the vehicle floor, and a second cavity is provided within the reinforcing beam.

[0009] Furthermore, the reinforcing beam is spaced apart from the supporting portion at both ends along the longitudinal direction, and the reinforcing beam includes a contoured portion corresponding to the protrusion, with the contoured portion and the protrusion spaced apart.

[0010] Furthermore, the crossbeam assembly also includes connecting plates, which are disposed at both ends of the crossbeam body along the lateral direction and are configured to connect with the vehicle body pillars.

[0011] Furthermore, the crossbeam assembly also includes a seat mounting bracket, which is disposed on the reinforcement and / or the connecting plate, and is configured to be connected to the seat.

[0012] Furthermore, it also includes a center channel bracket and an instrument mounting bracket. The center channel bracket is located in the middle of the crossbeam body and is connected to one end of the crossbeam body along the longitudinal direction. The instrument mounting bracket is set on the center channel bracket and / or the crossbeam body, and the instrument mounting bracket is set to be connected to the sub-instrument panel.

[0013] Another object of this embodiment is to provide a seat having the above-described crossbeam assembly.

[0014] Another object of this embodiment is to provide a vehicle provided with the aforementioned crossbeam assembly or seat.

[0015] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0016] The main body of the crossbeam includes a reinforcing section and a supporting section. The supporting section is connected to the vehicle floor. The two sides of the reinforcing section are connected to the supporting section and form a first cavity between the vehicle floor, which improves the energy absorption effect of the crossbeam.

[0029] Example 1

[0030] Reference Figures 1-4 The present invention provides a crossbeam assembly, including a crossbeam body 1. The crossbeam body 1 includes a reinforcing part 11 and a supporting part 12. The supporting part 12 is connected to both sides of the reinforcing part 11. The supporting part 12 is configured to be connected to the vehicle floor. A first cavity 2 is formed between the reinforcing part 11 and the vehicle floor. In the embodiment, the reinforcing part 11 is connected to the supporting part 12, and a first cavity 2 is formed between the reinforcing part 11 and the vehicle floor. When the vehicle is involved in a collision, the first cavity 2 deforms under force, improving the energy absorption capacity of the crossbeam assembly. Furthermore, the reinforcing part 11 includes a protrusion 111 extending toward the first cavity 2. In the embodiment, the reinforcing part 11... The reinforcement 11 includes protrusions 111 extending toward and away from the first cavity 2. In an embodiment, the reinforcement 11 includes protrusions 111 extending away from the first cavity 2. When the beam assembly is impacted, the protrusions 111 provide secondary support for the beam body 1. The reinforcement 11 may include one or more protrusions 111. The above embodiments can improve the strength and deformation resistance of the beam assembly. Compared with the traditional method of increasing the wall thickness of the beam body to improve the structural strength, this application can reduce the weight of the beam and reduce the cost by setting the first cavity 2 and the protrusions 111, while ensuring a certain beam strength and energy absorption effect.

[0031] In an embodiment, the reinforcing part 11 includes a protrusion 111 extending toward the first cavity 2 and extending away from the first cavity 2. The protrusion 111 includes a first protrusion extending toward the first cavity 2 and a second protrusion extending away from the first cavity 2, respectively. The first protrusion and the second protrusion are connected to each other to form a protrusion 111 with a cavity in the middle, which further improves the energy absorption effect. Both the first protrusion and the second protrusion can play a supporting role, which can further improve the strength of the beam.

[0032] As a preferred embodiment, the reinforcing portion 11 further includes a first reinforcing portion 112 and a second reinforcing portion 113, with the protrusion 111 disposed between the first reinforcing portion 112 and the second reinforcing portion 113. When the protrusion 111 extends toward the first cavity 2, the cross-sectional shape of the reinforcing portion 11 is "M"-shaped or "U"-shaped; when the protrusion 111 extends away from the first cavity 2, the cross-sectional shape of the reinforcing portion 11 is "T". When the protrusion 111 includes a first protrusion extending toward the first cavity 2 and a second protrusion extending away from the first cavity 2, the reinforcing portion 11 has a cavity, and the protrusion 111 is disposed between the first reinforcing portion 112 and the second reinforcing portion 113, further enhancing the strength of the crossbeam.

[0033] In one embodiment, the main body 1 of the crossbeam is made by pultrusion molding of a high-strength composite material. The high-strength composite material includes reinforcing fibers and organic resins. The reinforcing fibers include one of glass fiber, carbon fiber, aramid fiber, and basalt fiber. The organic resins include one of epoxy resin, polyester resin, and vinyl ester resin. While ensuring the strength requirements of the main body 1 of the crossbeam and guaranteeing safety, the requirements for weight reduction are met, and lightweighting is achieved, which can reduce the weight of the main body 1 of the crossbeam.

[0034] In one embodiment, refer to Figure 2 The support part 12 includes a first support part 121 and a second support part 122 connected together. The second support part 122 is close to and connected to the vehicle floor. The end of the first support part 121 away from the second support part 122 is connected to the reinforcing part 11. An angle is formed between the first support part 121 and the second support part 122. The first support part 121 and the second support part 122 can support the crossbeam assembly from different angles, thereby improving the support capacity and structural strength of the crossbeam assembly.

[0035] In one embodiment, refer to Figure 2 The crossbeam assembly also includes a reinforcing beam 3, which is located within the first cavity 2 to enhance the structural strength of the crossbeam body 1. The reinforcing beam 3 is connected to both the crossbeam body 1 and the vehicle floor. In this embodiment, the upper part of the reinforcing beam 3 is connected to the reinforcing part 11 of the crossbeam body 1, and the bottom part of the reinforcing beam 3 is connected to the vehicle floor, providing vertical support for the crossbeam body 1 and ensuring the load-bearing capacity of the reinforcing beam 3 in the vertical direction to a certain extent. A second cavity 31 is provided inside the reinforcing beam 3. The second cavity 31 of the reinforcing beam 3 and the first cavity 2 of the crossbeam body 1 together form a double cavity structure, which effectively improves the strength of the crossbeam assembly and enhances safety performance.

[0036] In one embodiment, refer to Figure 2The reinforcing beam 3 is spaced apart from the support portion 12 at both ends along the longitudinal direction. The gap between the two ends of the reinforcing beam 3 and the support portion 12 can further enhance the energy absorption capacity of the beam. The reinforcing beam 3 includes a contoured portion 32 corresponding to the protrusion 111. In the embodiment, the contoured portion 32 and the protrusion 111 have similar shapes. The cross-sectional shape of the reinforcing beam 3 is set to a corresponding "M" shape, "U" shape or "T" shape. The strength of the beam body 1 is further improved by the contoured portion 32 and the protrusion 111. The spaced arrangement of the contoured portion 32 and the protrusion 111 can also enhance the energy absorption capacity of the beam.

[0037] It should be noted that, in the embodiment, if the reinforcing part 11 includes a protrusion 111 extending toward the first cavity 2 and extending away from the first cavity 2, wherein the protrusion 111 includes a first protrusion extending toward the first cavity 2 and a second protrusion extending away from the first cavity 2, then the contour part 32 in the reinforcing beam 3 is similar in shape to the first protrusion, thereby reducing the material used in the reinforcing beam 3 and lowering the cost.

[0038] As a preferred option, the length of the bottom surface of the reinforcing beam 3 in the longitudinal direction is less than the length of the top surface in the longitudinal direction. Without affecting the supporting strength of the main beam 1, the volume and weight of the reinforcing beam 3 can be reduced, thus achieving further weight reduction.

[0039] It should be noted that the reinforcing beam 3 is made of high-strength composite material. Furthermore, the gap between the reinforcing beam 3 and the main body of the crossbeam 1 can be connected together with epoxy resin. By using high-strength composite material and epoxy resin, the weight is greatly reduced while ensuring the overall structural strength of the crossbeam assembly, and the cost can also be reduced. Furthermore, multiple through holes are also provided on the side wall of the main body of the crossbeam 1. The through holes can further reduce the weight of the crossbeam assembly and also serve to arrange pipelines and drainage.

[0040] In one embodiment, refer to Figure 1 , Figure 3 and Figure 4 The crossbeam assembly also includes a connecting plate 4, which is disposed at both ends of the crossbeam body 1 along the lateral direction. The lateral direction is X, which is the width direction of the vehicle body; the longitudinal direction is Y, which is the length direction of the vehicle body; and the vertical direction is Z, which is the height direction of the vehicle body. The lateral, longitudinal, and vertical directions are perpendicular to each other. The connecting plate 4 is configured to connect with the vehicle body pillars, which can improve the stability of the connection between the crossbeam assembly and the vehicle body. The vehicle body pillars can be the A-pillar, B-pillar, or C-pillar of the vehicle. This application does not limit this.

[0041] As a preferred embodiment, the connecting plate 4 includes an extension that is connected to the reinforcing portion 11 and the protrusion 111 and extends away from the side of the crossbeam body 1 and is fixed to the vehicle body pillar. The connection plate 4 can improve the connection strength between the crossbeam body 1 and the vehicle frame and further improve the structural strength of the crossbeam assembly.

[0042] In one embodiment, refer to Figure 1 , Figure 3 and Figure 4 The crossbeam assembly also includes a seat mounting bracket 5, which is disposed on the reinforcing part 11 and / or the connecting plate 4. The seat mounting bracket 5 is configured to connect with the seat for mounting the seat. In the embodiment, when the seat mounting bracket 5 is disposed on the connecting plate 4, both the connecting plate 4 and the crossbeam body 1 can support the seat, thereby improving the stability of the seat installation.

[0043] When setting the seat mounting bracket 5, as a preferred embodiment, the protrusion 111 extends toward the first cavity 2, which can reduce the height of the crossbeam assembly in the vertical direction and facilitate the installation of the seat. Furthermore, a mounting part is provided at the bottom end of the seat mounting bracket 5, and the mounting part is connected to the protrusion 111 to improve the connection strength of the seat mounting bracket 5.

[0044] In one embodiment, refer to Figure 1 , Figure 3 and Figure 4 It also includes a central channel bracket 6 and an instrument mounting bracket 7. The central channel bracket 6 is located in the middle of the crossbeam body 1 and is connected to one end of the crossbeam body 1 along the longitudinal direction. The central channel bracket 6 is set on the central channel of the vehicle and is used to install equipment, which optimizes the spatial arrangement of the crossbeam assembly in the vehicle. As a preferred embodiment, the bottom of the central channel bracket 6 is connected to the vehicle floor, and a second cavity is formed between the central channel bracket 6 and the vehicle floor, which further strengthens the structural strength. The instrument mounting bracket 7 is set on the central channel bracket 6 and / or the crossbeam body 1. The instrument mounting bracket 7 is set to be connected to the sub-instrument panel, which optimizes the structural layout in the vehicle compartment. As a preferred embodiment, the instrument mounting bracket 7 has a cavity, which further strengthens the structural strength.

[0045] The working principle of the crossbeam assembly provided in this embodiment is as follows: The crossbeam body 1 includes a reinforcing part 11 and a supporting part 12. The supporting part 12 is connected to both sides of the reinforcing part 11 and is connected to the vehicle floor through the supporting part 12, forming a first cavity 2 between the supporting part 11 and the vehicle floor. The first cavity 2 enhances the energy absorption capacity of the crossbeam body 1. The reinforcing part 11 includes a protrusion 111 extending toward and / or away from the first cavity 2. The protrusion 111 extending toward and / or away from the first cavity 2 can provide secondary support for the vehicle pillars, improving the strength and deformation resistance of the crossbeam assembly. Compared with increasing the thickness of the crossbeam plate to improve the strength of the crossbeam assembly, by setting the first cavity 2 and the protrusion 111, the weight of the crossbeam assembly is reduced while meeting the collision strength requirements of the crossbeam assembly, thus reducing manufacturing costs and achieving lightweighting.

[0047] Unlike the above embodiments, this embodiment provides a seat with the aforementioned crossbeam assembly. By setting the first cavity 2 and the protrusion 111, the weight of the crossbeam assembly is reduced while meeting the collision strength requirements of the crossbeam assembly, thus reducing manufacturing costs and achieving lightweighting. Furthermore, the height of the crossbeam body 1 is reduced, thereby minimizing its impact on the vehicle's interior space.
