Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to a vehicle frame and a vehicle. Background Art

[0002] At present, the sales rate of the new energy heavy-duty truck market continues to increase, and the structure of heavy-duty vehicles in the market is diversified (back charging, back battery replacement, side charging, bottom battery replacement, extended range, etc.). Among them, when the frame of the extended-range new energy heavy-duty truck structure does not use crossbeams or the crossbeam span is large, the fuel tank and side-mounted power batteries are arranged on both sides, resulting in inconsistent weight distribution of accessories on the left and right sides of the vehicle, and then the left and right longitudinal beams of the frame are unevenly stressed, resulting in inconsistent deformation on both sides of the frame; when conventional trough-shaped crossbeams are used, due to the high space utilization rate of the second-class chassis, the trough-shaped crossbeams will affect the layout of parts and the assembly efficiency of parts. Utility Model Content

[0003] In view of this, the present application provides a vehicle frame to improve the uniformity of the force applied to the two longitudinal beams of the vehicle frame without affecting the arrangement of components and assembly efficiency. In addition, the present application also provides a vehicle including the above-mentioned vehicle frame.

[0004] In order to achieve the above objectives, this application provides the following technical solutions:

[0005] A vehicle frame comprising:

[0006] Two longitudinal beams arranged parallel and spaced apart;

[0007] A first crossbeam is connected between the two longitudinal beams, wherein both ends of the first crossbeam are detachably fixedly connected to the longitudinal beams, and the first crossbeam is plate-shaped and its plate surface extends along the supporting direction of the frame.

[0008] Optionally, both ends of the first crossbeam are connected to the longitudinal beam via a connecting assembly, and the connecting assembly includes:

[0009] a first connecting portion fixed to the longitudinal beam;

[0010] A second connection portion is integrated on the first connection portion or fixedly connected to the first connection portion, and the second connection portion is detachably fixedly connected to the first crossbeam.

[0011] Optionally, the ends of the first cross beam are connected to the same longitudinal beam through multiple connecting components.

[0012] Optionally, both the first connecting portion and the second connecting portion are plate-shaped sheet metal parts, and there is an angle between the two.

[0013] Optionally, the first connecting portion is configured as a hollow structure for avoiding the bolt holes on the longitudinal beam.

[0014] Optionally, both ends of the first crossbeam are provided with wire-passing notches, and the second connecting portion is provided with a wire-passing through hole that passes through the second connecting portion along the length direction of the longitudinal beam at a position corresponding to the wire-passing notches.

[0015] Optionally, an arc-shaped avoidance groove is provided at the bottom of the first crossbeam.

[0016] Optionally, the thickness of the first crossbeam is 12-20 mm.

[0017] Optional, including:

[0018] A second crossbeam is parallel to and spaced apart from the first crossbeam and is connected between the two longitudinal beams. The second crossbeam is a channel steel structure or an I-beam structure.

[0019] A vehicle comprises the above-mentioned frame.

[0020] Since the first crossbeam and the longitudinal beam of the vehicle frame provided by the present application are detachably connected, the accessories can be assembled first and then the first crossbeam can be connected to the longitudinal beam. In this way, the interference of the first crossbeam with the accessory assembly process can be avoided, which is conducive to improving assembly efficiency.

[0021] Furthermore, the first crossbeam in the frame is plate-shaped, which occupies less space along the length of the longitudinal beams. This helps prevent interference between the first crossbeam and the accessories, thereby reducing the span between the frame crossbeams and improving the overall deformation resistance of the frame. Furthermore, compared to trough-shaped crossbeams in related technologies, the plate-shaped first crossbeam also contributes to vehicle lightweighting. Furthermore, it should be noted that the force exerted on the frame by the accessories is parallel to the direction of gravity, while typically the support direction is parallel to and opposite to the direction of gravity. Therefore, in the present application, the plate surface of the first crossbeam extends along the support direction of the frame, effectively improving the first crossbeam's deformation resistance under the aforementioned forces, thereby better supporting and distributing the forces. Specifically, when the accessories are attached to one longitudinal beam, the force exerted by the accessories on the longitudinal beam is transmitted to the other longitudinal beam via the first crossbeam, thereby balancing the forces on the two longitudinal beams, improving the overall deformation resistance of the frame, and preventing inconsistent deformation of the two longitudinal beams.

[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] The frame in the embodiment of the present application is the load-bearing component of the vehicle, which is particularly suitable for scenarios where the chassis space utilization rate is high and the weight of the accessories on the two longitudinal beams 1 are inconsistent. The above-mentioned accessories refer to: components installed on the longitudinal beam 1, such as the engine, battery and battery frame.

[0033] like Figure 1 and Figure 2 As shown, the vehicle frame in the embodiment of the present application includes two longitudinal beams 1 and a first cross beam 2, wherein the two longitudinal beams 1 are parallel and spaced apart, the first cross beam 2 is connected between the two longitudinal beams 1, and both ends of the first cross beam 2 are detachably fixedly connected to the longitudinal beams 1, that is, the first cross beam 2 and the longitudinal beam 1 are detachably connected, and in the connected state, the first cross beam 2 cannot rotate relative to the longitudinal beam 1 with the connection position as the center of the circle; in addition, the first cross beam 2 is plate-shaped and its plate surface extends along the support direction of the vehicle frame, and the support direction of the vehicle frame is Figure 1 The direction of the z-axis.

[0034] When assembling accessories on a vehicle using the above-mentioned frame, since the first crossbeam 2 and the longitudinal beam 1 are detachably connected, the accessories can be assembled first and then the first crossbeam 2 can be connected to the longitudinal beam 1. In this way, interference of the first crossbeam 2 with the accessory assembly process can be avoided, which is conducive to improving assembly efficiency.

[0035] The first crossbeam 2 in the vehicle frame is plate-shaped, occupying less space along the length of the longitudinal beam 1. This helps prevent interference between the first crossbeam 2 and the accessories, thereby reducing the span between the frame crossbeams and improving the overall deformation resistance of the vehicle frame. Furthermore, compared to trough-shaped crossbeams in related art, the plate-shaped first crossbeam 2 also contributes to vehicle lightweighting. Furthermore, it should be noted that the force exerted on the vehicle frame by the accessories is parallel to the direction of gravity, while the support direction is typically parallel to and opposite to the direction of gravity. Therefore, in this application, the plate surface of the first crossbeam 2 extends along the support direction of the vehicle frame, effectively improving the first crossbeam 2's deformation resistance under the aforementioned forces, thereby better supporting and distributing the forces. Specifically, when the accessories are attached to one longitudinal beam 1, the force exerted by the accessories on the longitudinal beam 1 is transmitted to the other longitudinal beam 1 via the first crossbeam 2, thereby balancing the forces on the two longitudinal beams 1, improving the overall deformation resistance of the vehicle frame, and preventing inconsistent deformation of the two longitudinal beams 1 of the frame.

[0036] Regarding the arrangement position of the first cross beam 2 on the longitudinal beam 1, in some optional embodiments, such as Figure 1 and Figure 2 As shown, the first crossbeam 2 is arranged above a certain accessory (such as an engine). Or, in other optional embodiments, the first crossbeam 2 can also be arranged in the gap between two accessories.

[0037] In some optional embodiments, such as Figure 1As shown, both ends of the first crossbeam 2 are connected to the longitudinal beam 1 through a connecting assembly 4, and the connecting assembly 4 includes a first connecting portion 401 and a second connecting portion 402, wherein the first connecting portion 401 is fixed to the longitudinal beam 1, specifically, it can be welded or screwed, etc., and this application does not limit this. The second connecting portion 402 is integrated into the first connecting portion 401 or the second connecting portion 402 is fixedly connected to the first connecting portion 401, that is, the second connecting portion 402 and the first connecting portion 401 are integrally formed or the second connection is an independent structure and is fixedly connected to the first connecting portion 401. When the second connection is an independent structure and is fixedly connected to the first connecting portion 401, its connection method can be welding or screwing, and this application also does not limit this. The second connecting portion 402 is detachably fixedly connected to the first crossbeam 2, and then the connection between the first crossbeam 2 and the longitudinal beam 1 is achieved by using the connecting assembly 4. Under this setting mode, during the vehicle assembly process, the connecting component 4 can be pre-set on the longitudinal beam 1, and then the accessories can be assembled, and finally the connecting component 4 can be used to realize the connection between the first crossbeam 2 and the longitudinal beam 1; under this assembly sequence, on the one hand, it can avoid the first crossbeam 2 interfering with the installation of the accessories, thereby ensuring the assembly efficiency; on the other hand, when the longitudinal beam 1 adopts a channel steel structure, the part of the connecting component 4 used to connect to the first crossbeam 2 can extend to the outside of the groove of the channel steel structure, thereby avoiding the groove of the channel steel structure restricting the working space when the first crossbeam 2 is assembled, thereby helping to improve the assembly efficiency.

[0038] In other optional embodiments, both ends of the first crossbeam 2 are directly fixed to the longitudinal beam 1, that is, both ends of the first crossbeam 2 have connection structures that can be directly connected to the longitudinal beam 1. In one exemplary embodiment, the first crossbeam 2 and the longitudinal beam 1 are detachably connected via bolts. Specifically, the longitudinal beam 1 has a first bolt hole at the location where the first crossbeam 2 is connected, and the end of the first crossbeam 2 is bent and provided with a second bolt hole. During connection, after aligning the first bolt hole with the second bolt hole, a bolt is inserted through the first and second bolt holes, and the nut is tightened to achieve the connection between the first crossbeam 2 and the longitudinal beam 1. This arrangement helps simplify the connection structure between the first crossbeam 2 and the longitudinal beam 1 and further improves the overall strength of the vehicle frame.

[0039] Furthermore, on the basis of the first crossbeam 2 being connected to the longitudinal beam 1 via the connecting assembly 4, the ends of the first crossbeam 2 are connected to the same longitudinal beam 1 via multiple connecting assemblies 4. In other words, multiple connecting assemblies 4 are simultaneously provided at a certain part of the same longitudinal beam 1 (the part being the part of the longitudinal beam 1 that is subjected to greater force and needs to be reinforced by the first crossbeam 2), and the multiple connecting assemblies 4 are simultaneously connected to the ends of the first crossbeam 2. In this way, the connection strength between the first crossbeam 2 and the longitudinal beam 1 can be effectively increased. In an exemplary embodiment, as Figure 2 and Figure 5As shown, the ends of the first crossbeam 2 are connected to the same longitudinal beam 1 via two connecting assemblies 4. The two connecting assemblies 4 extend along the length of the longitudinal beam 1, and an installation gap is formed between the second connecting portions 402 of the two connecting assemblies 4. During installation, the ends of the first crossbeam 2 are placed in the installation gap and connected using a connecting structure such as bolts. Of course, the number and location of the connecting assemblies 4 can be adaptively adjusted as needed. For example, the number of connecting assemblies 4 can be increased to 3, 4, or 5, etc. The location of the connecting assemblies 4 can also be set along the supporting direction of the longitudinal beam 1. In the assembled state (i.e., when the first crossbeam 2 is connected to the longitudinal beam 1), the connecting assemblies 4 are all located on one side of the first crossbeam 2.

[0040] In some embodiments, as Figure 3-Figure 5 As shown, the first connecting portion 401 and the second connecting portion 402 are both plate-shaped sheet metal parts, and an angle is formed between them. The size of the angle can be adaptively adjusted as needed during the specific implementation process. For example, the angle between the first connecting portion 401 and the second connecting portion 402 can be 90°, or the angle between the first connecting portion 401 and the second connecting portion 402 can be 85°, etc.

[0041] In other embodiments, the first connection portion 401 and the second connection portion 402 are integrally formed and are a casting or a removed-material-machined part (ie, a part formed by removing material).

[0042] Furthermore, the first connecting portion 401 is configured as a hollow structure to avoid the bolt holes on the longitudinal beam 1. Thus, during assembly, after the first connecting portion 401 is fixed to the longitudinal beam 1, it does not block the bolt holes on the longitudinal beam 1, thereby ensuring the subsequent installation of components such as the battery frame that are bolted to the longitudinal beam 1. In other words, this embodiment, through the aforementioned hollow structure, effectively prevents interference between components such as the battery frame that are bolted to the longitudinal beam 1 and the connecting assembly 4, thereby facilitating the rationality of the placement of the first crossbeam 2 and thereby improving the frame's deformation resistance and force uniformity.

[0043] It should be noted that the above-mentioned hollow structure can be a square hole, a round hole and / or a special-shaped hole that passes through the first connecting part 401. During specific implementation, it can be adaptively designed according to needs. It only needs to ensure the structural strength of the first connecting part 401 itself and ensure that it does not block the bolt holes on the longitudinal beam 1.

[0044] Furthermore, in some embodiments, both ends of the first crossbeam 2 are provided with wire-passing notches, and the position of the second connecting portion 402 corresponding to the wire-passing notch is provided with a wire-passing through-hole that passes through the second connecting portion 402 along the length direction of the longitudinal beam 1. That is to say, in the assembled state, the combined structure formed by the first crossbeam 2 and the connecting component 4 has a wire-passing through-hole that passes through the above-mentioned combined structure along the length direction of the longitudinal beam 1. During the vehicle assembly process, control lines, electrical connection lines and other lines can pass through the above-mentioned wire-passing through-holes, which is more conducive to optimizing the line layout. In addition, the above-mentioned wire-passing through-holes can also be used as a wiring harness structure, which is conducive to improving the orderliness of the vehicle wiring harness. In some exemplary embodiments, such as Figure 3 and Figure 4 As shown, the wire through hole is semicircular, and a plurality of bolts are provided between the first crossbeam 2 and the connecting assembly 4 to achieve a detachable fixed connection between the two; and a plurality of bolts are circumferentially arranged around the arc section of the wire through hole, which is more conducive to improving the connection strength between the two.

[0045] Furthermore, an avoidance groove is provided at the bottom of the first crossbeam 2. That is, an avoidance groove is provided on the side of the first crossbeam 2 close to the ground, which can reduce the probability of interference between the first crossbeam 2 and the accessories, and is more conducive to the reasonable arrangement of the first crossbeam 2. In addition, the shape of the avoidance groove can be adaptively adjusted as needed, for example, it can be set as follows Figure 3 and Figure 4 The arc-shaped avoidance groove shown can also be set as a square groove, etc.

[0046] In some embodiments, the thickness of the first beam 2 is 12-20 mm. The thickness of the first beam 2 refers to the distance between two opposite plates in the first beam 2.

[0047] Furthermore, in some embodiments, Figure 1 and Figure 2 As shown, the vehicle frame further includes a second crossbeam 3, which is spaced apart from and parallel to the first crossbeam 2 and connected between the two longitudinal beams 1. Furthermore, the second crossbeam 3 can be a channel steel structure or an I-beam structure. By providing different types of crossbeams at different positions on the longitudinal beams 1, the structural strength of the vehicle frame is further improved.

[0048] In addition, an embodiment of the present application also provides a vehicle, which includes the above-mentioned frame. It should be noted that since the vehicle in this embodiment includes the above-mentioned frame, the beneficial effects brought about by the vehicle and the frame are discussed in detail above, and this application will not repeat them here.
