Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts, and in particular to a vehicle frame and vehicle. Background Technology

[0002] The subframe is a component of the front and rear axles. While reducing vehicle vibration, it also enhances the torsional rigidity of the vehicle body. For rear-wheel drive and four-wheel drive vehicles, the drive system drives the rear wheels of the car. The internal thermal management, on-board systems and other components of the car are located at the front of the rear subframe. When the car's center column is impacted, the internal thermal management, on-board systems and other components intrude into the rear subframe, causing the frame firewall intrusion to exceed the standard, which in turn affects the vehicle's drive.

[0003] To reduce the impact of the center column on the frame, the existing method is to strengthen the rear subframe by installing multiple reinforcing brackets between the frame crossbeams. However, this method requires too many reinforcing brackets and mounting points, making the installation process complex. Furthermore, while the strength is high, the deformation energy absorption capacity is low, and it cannot reduce the amount of frame intrusion. Utility Model Content

[0004] To address the technical problems of the aforementioned subframe reinforcement requiring numerous reinforcing brackets and reinforcement points, complex installation process, and inability to reduce frame intrusion, this utility model provides a frame and vehicle.

[0005] To achieve the above objectives, this utility model provides a vehicle frame, including a frame body, the frame body including a first crossbeam and a second crossbeam disposed opposite to each other, the first crossbeam being located away from the central axis of the vehicle body in the length direction relative to the second crossbeam; an energy-absorbing structure including a curved portion and an extension portion, the extension portion being disposed at both ends of the curved portion, the curved portion and the extension portion being integrally formed; the curved portion being connected to the first crossbeam, and the end of the extension portion away from the curved portion being connected to the second crossbeam.

[0006] Furthermore, the curved portion is connected to the inner wall of the first crossbeam, and the extension portion is connected to the top surface of the second crossbeam.

[0007] Furthermore, the thickness of the curved portion along the length direction of the vehicle body is less than or equal to the thickness of the extended portion along the width direction of the vehicle body.

[0008] Furthermore, the two ends of the curved portion extend toward the second crossbeam in opposite directions, and the extension direction of the extended portion is on the same straight line as the extension direction of the two ends of the curved portion.

[0009] Furthermore, the frame also includes a bracket, one end of which is connected to the frame body and the other end of which is connected to the extension.

[0010] Furthermore, the frame body also includes connecting beams spaced apart and connected to one end of the first crossbeam and the second crossbeam, the extension is located between the spaced connecting beams, and one end of the bracket is fixed to the top surface of the connecting beam.

[0011] Furthermore, the support includes a first support and a second support, and the connecting beam includes a first connecting beam and a second connecting beam. The first support and the first connecting beam are connected, and the second support is connected to the second connecting beam.

[0012] Furthermore, the frame body also includes a reinforcing section, with the first connecting beam and the second connecting beam connected to both ends of the reinforcing section respectively, and a gap is provided between the reinforcing section and the energy-absorbing structure in the vertical direction.

[0013] Furthermore, a fixing part is provided on the top surface of the second crossbeam, and both the bracket and the extension are connected to the fixing part.

[0014] Another object of this embodiment is to provide a vehicle having the aforementioned frame.

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

[0016] (1) An energy-absorbing structure is installed between the two crossbeams of the frame. The energy-absorbing structure includes a bending part and an extension part. The bending part is connected to the first crossbeam. During a collision, the bending part absorbs the collision force and deforms to achieve the energy-absorbing effect. The extension part is fixed at both ends of the bending part and connected to the second crossbeam to disperse the collision force acting on the bending part and ensure the stability of the connection between the energy-absorbing structure and the second crossbeam. Since this frame only needs to set an energy-absorbing structure in the frame body to solve the problem of excessive intrusion after the collision of the frame, the structure is simple and easy to implement.

[0017] (2) A bracket is installed on the extension of the energy-absorbing structure. The bracket is connected to the connecting beam in the frame body, which can further improve the stability of the root of the energy-absorbing structure. Attached Figure Description

[0029] Example 1

[0030] like Figures 1-3 As shown, the vehicle frame provided in this embodiment includes a frame body 1 and an energy-absorbing structure 2. The frame body 1 includes a first crossbeam 110 and a second crossbeam 120 arranged opposite to each other. The first crossbeam 110 is located away from the central axis of the vehicle in the length direction relative to the second crossbeam 120. Figure 1 and Figure 3 In the X direction, the vehicle width direction is Figure 1 and Figure 3In the Y-direction, when the frame body 1 is positioned at the front of the vehicle, the first crossbeam 110 is farther from the longitudinal centerline of the vehicle frame relative to the second crossbeam 120, meaning the first crossbeam 110 is closer to the front of the vehicle relative to the second crossbeam 120. When the frame body 1 is positioned at the rear of the vehicle, the first crossbeam 110 is farther from the longitudinal centerline of the vehicle frame relative to the second crossbeam 120, meaning the first crossbeam 110 is closer to the rear of the vehicle relative to the second crossbeam 120. In this embodiment, with the frame body 1 positioned at the front of the vehicle, when the vehicle's center pillar impacts, the first crossbeam 110 first bears the impact force. In this embodiment, the first crossbeam 110 and the second crossbeam 120 are arranged parallel to each other. The energy-absorbing structure 2 includes a bent portion 210 and an extension portion 220. The extension portion 220 is located at both ends of the bent portion 210. The bent portion 210 is connected to the first crossbeam 110, and the extension portion 220 is farther from the bent portion 210. The first crossbeam 110 is connected to the second crossbeam 120. In this embodiment, since the first crossbeam 110 is closer to the front of the vehicle, when the center column is impacted, the first crossbeam 110 is impacted and intrudes into the second crossbeam 120. During the intrusion, the impact force is transmitted to the bending portion 210 connected to the first crossbeam 110. The bending portion 210 absorbs the impact force of the first crossbeam 110 and bends and deforms, thereby absorbing the impact. In addition, since the extension portions 220 at both ends of the bending portion 210 are connected to the second crossbeam 120, when the force is transmitted to the bending portion 210, the force can be divided into two and transmitted to the second crossbeam 120. The energy-absorbing structure 2 absorbs the impact force through deformation on the one hand, and disperses the force on the other hand, ensuring the stability of the connection between the energy-absorbing structure 2 and the second crossbeam 120, avoiding the deformation of the second crossbeam 120, and thus solving the problem of excessive deformation intrusion of the frame.

[0031] As a preferred embodiment, the energy-absorbing structure 2 is an integral circular beam. The circular beam can avoid stress concentration and can better disperse the collision force compared to a square beam. The middle part of the energy-absorbing structure 2 is a curved part 210 formed by flattening under pressure and bending on both sides. The two ends of the energy-absorbing structure 2 are extensions 220 extending along the bending direction of the two ends of the curved part 210. The energy-absorbing structure 2 is connected to the first crossbeam 110 through the curved part 210 in the middle and to the second crossbeam 120 through the extensions 220 at both ends. The required installation points are also fewer, the structure is simple, and it is easy to install. In the embodiment, the installation point between the energy-absorbing structure 2 and the first crossbeam 110 is the existing interface used for lifting the crossbeam mode, and the installation point between the energy-absorbing structure 2 and the second crossbeam 120 is the existing suspension installation point. Furthermore, the energy-absorbing structure 2 is installed with the first crossbeam 110 and the second crossbeam 120 using M12 bolts.

[0032] In one embodiment, refer to Figure 1The curved portion 210 is connected to the inner wall of the first crossbeam 110, and the extension portion 220 is connected to the top surface of the second crossbeam 120. When the first crossbeam 110 is impacted and intrudes backward, the force can be completely transmitted to the curved portion 210, which facilitates the energy absorption of the curved portion 210. In the embodiment, the first crossbeam 110 is the front beam and the second crossbeam 120 is the rear beam. In actual application, the height of the first crossbeam 110 in the vertical direction is higher than that of the second crossbeam 120 in the vertical direction. Connecting the extension portion 220 to the top surface of the second crossbeam 120 can maintain the relative height of the energy absorption structure 2. As a preferred embodiment, in order to ensure the stability of the connection between the extension portion 220 and the second crossbeam 120, the extension portion 220 is fitted to the top surface of the second crossbeam 120.

[0033] In one embodiment, refer to Figure 1 and 2 The thickness of the bent portion 210 along the length of the vehicle body is less than or equal to the thickness of the extension portion 220 along the width of the vehicle body, which reduces the strength of the bent portion 210. This allows the bent portion 210 to deform first when the energy-absorbing structure 2 is subjected to force. Preferably, the bent portion 210 is attached to the side wall of the first crossbeam 110, which further ensures the stability of the energy-absorbing deformation of the energy-absorbing structure 2.

[0034] In one embodiment, refer to Figure 1 and 2 The two ends of the curved portion 210 extend toward the second crossbeam 120 in opposite directions. The extension direction of the extension portion 220 is on the same straight line as the extension direction of the two ends of the curved portion 210. Preferably, the curved portion 210 has a symmetrical structure and the extension angles of the two ends are the same. In this embodiment, the curved portion 210 is fixed to the first crossbeam 110, and the two ends of the extension portion 220 away from the curved portion 210 are fixed to the second crossbeam 120 respectively. By fixing the curved portion 210 to the first crossbeam 110 and the extension portion 220 to the second crossbeam 120, and by making the curved portion 210 and the extension portion 220 an integral structure, the stability of the connection between the energy-absorbing structure 2 and the second crossbeam 120 can be further guaranteed.

[0035] In one embodiment, refer to Figure 1 The frame also includes a bracket 3, one end of which is connected to the frame body 1 and the other end is connected to the extension 220, providing further support for the extension 220, ensuring the stability of the extension 220, and thus preventing the second crossbeam 120 from deforming and intruding.

[0036] In one embodiment, refer to Figure 1 and 3The frame body 1 also includes connecting beams 130 that are spaced apart and connected to one end of the first crossbeam 110 and the second crossbeam 120. The extension 220 is located between the spaced connecting beams 130. One end of the bracket 3 is fixed to the surface of the connecting beam 130 and provides support for the bracket 3 from both sides of the first crossbeam 110 and the second crossbeam 120, further ensuring the stability of the extension 220 after being impacted.

[0037] In one embodiment, refer to Figure 1 and 2 The support 3 includes a first support 310 and a second support 320, and the connecting beam 130 includes a first connecting beam 131 and a second connecting beam 132. The first support 310 connects the first connecting beam 131 and an extension 220 close to the first connecting beam 131, and the second support 320 connects the second connecting beam 132 and an extension 220 close to the second connecting beam 132. This reduces the length of the support 3 and avoids installation problems caused by their intersection. Furthermore, the first support 310 and the second support 320 are symmetrically arranged along the central axis, which further enhances the energy absorption effect of the support 3 and maintains the stability of the energy absorption structure 2 during collision.

[0038] In one embodiment, refer to Figure 1 and 3 The frame body 1 also includes a reinforcing part 140. The two ends of the reinforcing part 140 are respectively connected to the first connecting beam 131 and the second connecting beam 132. There is a gap between the reinforcing part 140 and the energy-absorbing structure 2 in the vertical direction. The reinforcing part 140 improves the strength of the frame body 1. The gap between the energy-absorbing structure 2 and the reinforcing part 140 avoids the reinforcing part 140 from affecting the energy-absorbing deformation of the energy-absorbing structure 2.

[0039] In one embodiment, refer to Figure 1 The top surface of the second crossbeam 120 is provided with a fixing part 121. In this embodiment, the fixing part 121 is a mounting point on the suspension on the frame. The bracket 3 and the extension 220 are both connected to the fixing part 121, so that the connection positions of the bracket 3 and the extension 220 are the same, which reduces the number of mounting points of the energy-absorbing structure 2 and the bracket 3, simplifies the installation process, and can also enhance the energy absorption effect of the energy-absorbing structure 2.

[0040] The working principle of the frame in this embodiment is as follows: the bent portion 210 of the energy-absorbing structure 2 is fixed to the inner wall of the first crossbeam 110, and the extension portions 220 located at both ends of the bent portion 210 in the energy-absorbing structure 2 are fixed to the suspension mounting points on the top surface of the second crossbeam 120. One end of the first bracket 310 is connected to the first connecting beam 131, and the other end of the first bracket 310 is connected to the extension portion 220. One end of the second bracket 320 is connected to the second connecting beam 132, and the other end of the second bracket 320 is connected to the extension portion 220. Both the first bracket 310 and the second bracket 320 are fixed to the suspension mounting points. When the first crossbeam 110 is subjected to a central load... When a column collides, the impact force is transmitted from the bending portion 210 and dispersed to the second crossbeam 120 by the extensions 220 at both ends. The first bracket 310 and the second bracket 320 support the two extensions 220 respectively. When the impact force is too large, the bending portion 210 deforms and absorbs energy because the structural strength of the bending portion 210 is relatively weak. The second crossbeam 120 is supported by the extensions 220 and the first bracket 310 and the second bracket 320, which ensures the stability in the collision and prevents the second crossbeam 120 from deforming and intruding. Furthermore, the energy-absorbing structure 2 and the bracket 3 of this application have simple structures, require fewer installation points, and are easy to install.

[0041] Example 2

[0042] Unlike the above embodiments, this embodiment provides a vehicle equipped with the aforementioned frame. An energy-absorbing structure 2 and a support 3 are provided on the frame body 1. The energy-absorbing structure 2 and the support 3 absorb the impact force of the frame body 1 when it is hit by the center post, ensuring the stability of the impact and preventing the frame body 1 from being deformed and intruded too much due to the center post impact, which would affect the operation of the vehicle.
