TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a vehicle frame assembly and a vehicle. BACKGROUND

[0002] At present, in order to make the vehicle have certain stability during driving, a straight push rod and a transverse stabilizer bar are arranged on the vehicle frame, wherein the straight push rod is arranged to avoid displacement of the front and rear axles to a certain extent, and the transverse stabilizer bar is arranged to avoid excessive lateral roll of the vehicle body when turning to a certain extent, and the straight push rod is more commonly used in vehicles.

[0003] Generally, the vehicle frame includes two longitudinal beams and a cross beam connected between the two longitudinal beams, one end of the straight push rod is detachably connected with the cross beam through a push rod support arranged on the cross beam, the other end of the straight push rod extends in a direction approximately perpendicular to the extension direction of the cross beam and is connected with the rear axle; the transverse stabilizer bar is located between the two longitudinal beams, and the two ends of the transverse stabilizer bar are respectively connected with the two longitudinal beams through two transverse stabilizer bar supports.

[0004] However, in the above vehicle frame structure, when the vehicle body is subjected to a force in the front-rear direction, the straight push rod is subjected to a large force, which may cause the straight push rod to be damaged and fail, thereby affecting the stability of the vehicle during driving. SUMMARY

[0005] The present application provides a vehicle frame assembly and a vehicle, which can solve the problem of a large force on the straight push rod when the vehicle body is subjected to a force in the front-rear direction in the related art. The specific technical solutions are as follows:

[0006] In a first aspect, the present application provides a vehicle frame assembly, which includes vehicle body longitudinal beams and a push rod, and the vehicle body longitudinal beams are two; each vehicle body longitudinal beam is connected with a first support, and a mounting space with a socket is formed between the first support and the corresponding vehicle body longitudinal beam, and the direction of the socket is consistent with the extension direction of the vehicle body longitudinal beam; one end of the push rod is inserted into the mounting space through the socket and connected with the first support to be connected with the corresponding vehicle body longitudinal beam, and the other end of the push rod is used to be connected with the rear axle.

[0007] The vehicle frame assembly provided by the present application connects the push rod between the vehicle body longitudinal beam and the rear axle, and makes the extension direction of the push rod approximately consistent with the extension direction of the vehicle body longitudinal beam. In this way, when the vehicle is subjected to a force in the front-rear direction, the force on the push rod will be mostly absorbed by the vehicle body longitudinal beam, thereby avoiding damage and failure of the push rod to a certain extent, so as to make the stability of the vehicle during driving stronger.

[0008] As an optional implementation, the first support comprises a first extension part and a second extension part connected in sequence, the first extension part is connected to a side of the corresponding vehicle body longitudinal beam away from the other vehicle body longitudinal beam; an end of the second extension part not connected to the first extension part extends downward of the vehicle body longitudinal beam, the first extension part, the second extension part and the corresponding vehicle body longitudinal beam enclose the mounting space; one end of the push rod is connected between the second extension part and the corresponding vehicle body longitudinal beam, and in the width direction of the frame assembly, the size of the second extension part is smaller than the size of the corresponding vehicle body longitudinal beam. In this way, the first support is inverted "L" type, and when one end of the push rod is connected between the second extension part and the vehicle body longitudinal beam 1, since the size of the second extension part in the width direction of the frame assembly is smaller, when one end of the push rod is connected between the second extension part and the vehicle body longitudinal beam through the threaded fastener, it is more convenient to tighten the threaded fastener, so that the clamping force on the push rod is larger, and torque decay can be avoided to a certain extent.

[0009] As an optional implementation, each vehicle body longitudinal beam comprises a longitudinal beam body and a connecting part connected to the lower end of the longitudinal beam body; the first support is connected to the connecting part, and the mounting space is formed between the first support and the connecting part; one end of the push rod is inserted into the mounting space and connected between the first support and the connecting part. In this way, by providing the connecting part, the size and structure of the push rod can be matched to facilitate the connection of the push rod to the vehicle body longitudinal beam.

[0010] As an optional implementation, the connecting part comprises two connecting plates clamped together in the width direction of the frame assembly; the top end of the connecting plate is connected to the corresponding longitudinal beam body, and the two connecting plates and the corresponding longitudinal beam body enclose a closed space. In this way, by providing the connecting part comprising two connecting plates and making the two connecting plates and the longitudinal beam body enclose a closed space, the connection strength between the connecting part and the longitudinal beam body is higher, so that the strength of the vehicle body longitudinal beam is higher.

[0011] As an optional implementation, the frame assembly provided by the application further comprises a fastener; the connecting part further comprises a reinforcing part connected between the two connecting plates, the reinforcing part is located in the closed space, and the fastener passes through the first support, one end of the push rod and the reinforcing part in sequence to connect one end of the push rod between the first support and the connecting part. In this way, the strength of the connection between the push rod and the connecting part can be improved.

[0012] As an optional implementation, the two connecting plates are a first connecting plate and a second connecting plate, the first connecting plate is located on a side of the second connecting plate away from the other vehicle body longitudinal beam; a top end of the first connecting plate is welded to a side of the corresponding longitudinal beam body away from the other longitudinal beam body; a first weld joint is formed between the top end of the first connecting plate and the longitudinal beam body, and at least part of a trace of the first weld joint is a curve. In this way, the first weld joint formed between the first connecting plate and the longitudinal beam body is located on a side of the longitudinal beam body away from the other vehicle body longitudinal beam, so that the length of the first weld joint is larger, the connection strength between the first connecting plate and the corresponding longitudinal beam body is higher, and thus the connection strength between the connecting part and the corresponding longitudinal beam body is higher; in addition, by making the curvature of the first weld joint in the vehicle frame assembly height direction greater than 0, that is, the first weld joint is a curved weld joint rather than a straight weld joint in the length direction of the vehicle frame assembly, when the vehicle is subjected to a force in the front-rear direction, the force at the first weld joint can be decomposed in different directions to improve the strength of the first weld joint and further improve the connection strength between the connecting part and the corresponding longitudinal beam body.

[0013] As an optional implementation, the first support is connected to a side of the connecting part away from the other vehicle body longitudinal beam. In this way, interference with other components mounted on the vehicle body longitudinal beam can be avoided to some extent.

[0014] As an optional implementation, the vehicle frame assembly provided by the present application further comprises a transverse stabilizer bar, a second support spaced apart from the first support is connected to each connecting part; and two ends of the transverse stabilizer bar are respectively connected to the second support on the corresponding side of the vehicle body longitudinal beam. In this way, not only can the vehicle body longitudinal beam absorb the force received by the thrust rod, but also interference with other components due to the connection between the thrust rod and the vehicle body longitudinal beam can be avoided to some extent.

[0015] As an optional implementation, the two connecting plates are welded together, and a second weld joint is formed at the joint of the two connecting plates; and the second support surrounds at least part of the second weld joint. In this way, by surrounding at least part of the second weld joint with the second support, the force received by the connecting part will not directly act on the second weld joint, and the fatigue resistance of the vehicle body longitudinal beam after being connected with the first support and the second support is improved.

[0016] In a second aspect, the present application provides a vehicle comprising the vehicle frame assembly described above.

[0017] The vehicle frame assembly and the vehicle provided in the application, the vehicle frame assembly comprises two vehicle body longitudinal beams and a thrust rod; each vehicle body longitudinal beam is connected with a first support, and a mounting space with a socket is formed between the first support and the corresponding vehicle body longitudinal beam, and the direction of the socket is consistent with the extension direction of the vehicle body longitudinal beam; one end of the thrust rod is inserted into the mounting space through the socket and connected with the first support to be connected with the corresponding vehicle body longitudinal beam, and the other end of the thrust rod is used to be connected with the rear axle. The thrust rod is connected between the vehicle body longitudinal beam and the rear axle, and the extension direction of the thrust rod is consistent with the extension direction of the vehicle body longitudinal beam. In this way, when the vehicle is subjected to a force in the front-rear direction, the force on the thrust rod will be mostly absorbed by the vehicle body longitudinal beam, so that the thrust rod can be prevented from being damaged and disabled to a certain extent, and the stability of the vehicle during driving can be improved.

[0032] The technical solutions in the present application will be described clearly and completely below with reference to the drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " represents the meaning of or, for example, A / B can represent A or B: "and / or" in the text only describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which means that there are three cases of A alone, A and B together, and B alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0033] Hereinafter, the terms "first" and "second" are only for descriptive purposes, and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features.

[0034] At present, in order to make the vehicle have certain stability during driving, a straight thrust rod and a transverse stabilizer are arranged on the vehicle frame, wherein the straight thrust rod is arranged to avoid displacement of the front and rear axles of the vehicle to a certain extent, and the transverse stabilizer is arranged to avoid excessive lateral roll of the vehicle body when turning to a certain extent. The straight thrust rod is more commonly used in vehicles. Generally, the vehicle frame includes two longitudinal beams and a cross beam connected between the two longitudinal beams, the other end of the straight thrust rod extends in a direction approximately perpendicular to the extension direction of the cross beam and is connected with the rear axle; the transverse stabilizer is located between the two longitudinal beams, and the two ends of the transverse stabilizer are connected with the two longitudinal beams through two transverse stabilizer brackets respectively.

[0035] However, in the above vehicle frame structure, when the vehicle body is subjected to a force in the front-rear direction, since the extension direction of the straight thrust rod is approximately perpendicular to the extension direction of the cross beam, the cross beam cannot absorb the force received by the straight thrust rod, so that the straight thrust rod itself bears a large force, which may cause the straight thrust rod to be damaged and fail, thereby affecting the stability of the vehicle during driving.

[0036] Thus, the embodiment of the present application provides a vehicle frame assembly and a vehicle, wherein the vehicle frame assembly comprises two vehicle body side beams and a thrust rod; each vehicle body side beam is connected with a first support, and a mounting space with a socket is formed between the first support and the corresponding vehicle body side beam, and the direction of the socket is consistent with the extension direction of the vehicle body side beam; one end of the thrust rod is inserted into the mounting space through the socket and connected with the first support to be connected with the corresponding vehicle body side beam, and the other end of the thrust rod is used to be connected with the rear axle. In the vehicle frame assembly provided by the embodiment, the thrust rod is connected between the vehicle body side beam and the rear axle, and the extension direction of the thrust rod is consistent with the extension direction of the vehicle body side beam. In this way, when the vehicle is subjected to a front-rear direction force, the force on the thrust rod is more likely to be absorbed by the vehicle body side beam, so that the thrust rod can be prevented from being damaged and disabled to a certain extent, and the stability of the vehicle during driving can be improved.

[0037] The embodiment of the present application will be described in detail below with reference to the drawings and specific embodiments.

[0038] Please refer to FIG Figures 1 to 4 , Figure 1 The partial structure schematic diagram of the vehicle frame assembly provided by the embodiment of the present application is shown in FIG Figure 2 The partial structure schematic diagram of the vehicle frame assembly provided by the embodiment of the present application is shown in FIG Figure 1 The partial structure enlarged schematic diagram of the position A in FIG Figure 3 The partial structure schematic diagram of the vehicle frame assembly provided by the embodiment of the present application is shown in FIG Figure 1 The partial structure enlarged schematic diagram of the position B in FIG Figure 4 The partial structure enlarged schematic diagram of the position B in FIG Figure 3 As shown in FIG Figures 1 to 4 , the vehicle frame assembly provided by the embodiment comprises two vehicle body side beams 1 and a thrust rod 2, the two vehicle body side beams 1 are arranged along the width direction of the vehicle frame assembly, and the vehicle body side beams 1 are rear side beams; each vehicle body side beam 1 is connected with a first support 3, and a mounting space 4 with a socket is formed between the first support 3 and the corresponding vehicle body side beam 1, and the direction of the socket is consistent with the extension direction of the vehicle body side beam 1; one end of the thrust rod 2 is inserted into the mounting space 4 through the socket and connected with the first support 3 to be connected with the corresponding vehicle body side beam 1, and the other end of the thrust rod 2 is used to be connected with the rear axle. In the vehicle frame assembly provided by the embodiment, the thrust rod 2 is connected between the vehicle body side beam 1 and the rear axle, and the extension direction of the thrust rod 2 is consistent with the extension direction of the vehicle body side beam 1. In this way, when the vehicle is subjected to a front-rear direction force, the force on the thrust rod 2 is more likely to be absorbed by the vehicle body side beam 1, so that the thrust rod 2 can be prevented from being damaged and disabled to a certain extent, and the stability of the vehicle during driving can be improved.

[0039] In the embodiment, the frame assembly further comprises a plurality of cross beams 10 connected between the two body side rails 1. Details of other components of the frame assembly are not described herein.

[0040] It should be noted that in the embodiment, the thrust rod 2 is a straight thrust rod, and the connection point between the rear axle and the thrust rod 2 changes with the position of the thrust rod 2, but the overall structure and position of the rear axle do not change. Details are not described herein.

[0041] Further, in order to facilitate the installation of the thrust rod 2, in the embodiment, one end of the thrust rod 2 is detachably connected between the first support 3 and the body side rail 1. In this way, the installation of the thrust rod 2 is facilitated, and the installation efficiency of the frame assembly provided in the embodiment is improved. The detachable connection can be achieved by connecting one end of the thrust rod 2 to the first support 3 and the body side rail 1 by a threaded fastener, and details are not limited herein.

[0042] Please continue to see Figure 5 and Figure 6 , Figure 5 is Figure 3 a partial structure schematic view, Figure 6 is Figure 5 a partial structure enlarged schematic view at C in FIG. 4. As shown in Figure 5 and Figure 6 , in order to enable the end of the thrust rod 2 to extend into the mounting space 4 and be connected to the first support 3, in some alternative embodiments, the first support 3 comprises a first extension 31 and a second extension 32 connected in sequence. Specifically, one end of the first extension 31 is connected to the side of the corresponding body side rail 1 away from the other body side rail 1, and the other end of the first extension 31 extends away from the body side rail 1 in the width direction of the vehicle assembly. One end of the second extension 32, which is not connected to the first extension 31, extends downward of the body side rail 1, and the first extension 31, the second extension 32 and the corresponding body side rail 1 enclose the mounting space 4. One end of the thrust rod 2 is connected between the second extension 32 and the corresponding body side rail 1, and in the width direction of the frame assembly, the size of the second extension 32 is smaller than that of the corresponding body side rail 1. In this way, the first support 3 is in the shape of an inverted "L", and when one end of the thrust rod 2 is connected between the second extension 32 and the body side rail 1, since the size of the second extension 32 in the width direction of the frame assembly is smaller, it is easier to tighten the threaded fastener when connecting one end of the thrust rod 2 to the second extension 32 and the body side rail 1 by the threaded fastener, so that the thrust rod 2 is subjected to a larger clamping force, and torque decay can be avoided to some extent.

[0043] It should be noted that the width direction of the above-mentioned vehicle frame assembly is consistent with the y-axis direction in Figure 1 The lower part of the above-mentioned vehicle body longitudinal beam 1 can be understood as the ground-facing direction of the vehicle body longitudinal beam 1 during use of the vehicle.

[0044] In some optional embodiments, the first extension 31 and the second extension 32 are integrally connected, for example, the first extension 31 or the second extension 32 can be formed by bending the sheet metal part. Here, the connection between the first extension 31 and the second extension 32 is not limited.

[0045] In order to match the size and shape of the thrust rod 2, in some embodiments, each vehicle body longitudinal beam 1 includes a longitudinal beam body 11 and a connecting part 12 connected to the lower end of the longitudinal beam body 11; the first bracket 3 is connected to the connecting part 12, and the mounting space 4 is formed between the first bracket 3 and the connecting part 12, and one end of the thrust rod 2 is inserted into the mounting space 4 and connected between the first bracket 3 and the connecting part 12. In this way, by providing the connecting part 12, the size and structure of the thrust rod 2 can be matched to facilitate the connection of the thrust rod 2 to the vehicle body longitudinal beam 1.

[0046] Specifically, the end of the first extension 31 away from the second extension 32 is connected to the connecting part 12 by welding. It should be noted that in some other embodiments, the first extension 31 and the connecting part 12 can also be connected by other connection methods. Here, they are not introduced one by one.

[0047] Please continue to refer to Figure 7 , Figure 7 The three-dimensional structure of the connecting part in the vehicle frame assembly provided by the embodiments of the present application is shown. In order to increase the contact area between the connecting part 12 and the longitudinal beam body 11, and to increase the strength of the connecting part 12 and the longitudinal beam body 11, in some optional embodiments, the connecting part 12 includes two connecting plates that are buckled together along the width direction of the vehicle frame assembly; the top end of the connecting plate is connected to the corresponding longitudinal beam body 11, and the two connecting plates and the corresponding longitudinal beam body 11 form an enclosed space. In this way, by providing the connecting part 12 including two connecting plates and forming an enclosed space between the two connecting plates and the longitudinal beam body 11, the connection strength between the connecting part 12 and the longitudinal beam body 11 is higher, so that the strength of the vehicle body longitudinal beam 1 is higher.

[0048] It should be noted that since some weight-reducing holes or holes for internal wiring need to be provided on the vehicle body longitudinal beam 1, the above-mentioned enclosed space can be understood as relatively closed, rather than absolutely closed, that is, some weight-reducing holes can also be provided on the above-mentioned connecting part 12. Here, it is not limited.

[0049] Please continue reading Figure 8 , Figure 8 This is a schematic diagram illustrating the connection relationship between the thrust rod, the first bracket, and the connecting portion in the frame assembly provided in this application embodiment. Figure 8 As shown, in order to connect one end of the thrust rod 2 between the second extension 32 and the connecting part 12, the frame assembly provided in this embodiment also includes a fastener 5. The connecting part 12 also includes a reinforcing part 121 connected between two connecting plates. The reinforcing part 121 is located in an enclosed space. In order to improve the strength of the connection between the thrust rod 2 and the connecting part 12, in some optional embodiments, the fastener 5 passes through the first bracket 3, one end of the thrust rod 2 and the reinforcing part 121 in sequence to connect one end of the thrust rod 2 between the first bracket 3 and the connecting part 12. Specifically, the other end of the fastener 5 passes through one end of the thrust rod 2 and the second extension 32. The second extension 32 is provided with a threaded hole 321 for the fastener 5 to pass through.

[0050] In some alternative embodiments, the aforementioned reinforcing part 121 may be a reinforcing sleeve that penetrates both connecting plates simultaneously, and the end of the fastener 5 extends into the inner hole of the reinforcing sleeve and is connected to the inner hole.

[0051] It should be noted that, in order to avoid interference with other components installed on the vehicle body longitudinal beam 1 to a certain extent, in some embodiments, the first extension 31 should be connected to the side of the connecting part 12 opposite to the other vehicle body longitudinal beam 1.

[0052] Figures 6 to 8 As shown, in a specific implementation of this embodiment, the two connecting plates are a first connecting plate 122 and a second connecting plate 123. The first connecting plate 122 is located on the side of the second connecting plate 123 away from the other longitudinal beam 1. The top end of the first connecting plate 122 is connected to the side of the corresponding longitudinal beam body 11 away from the other longitudinal beam body 11, and at least part of the trajectory of the first weld 6 formed between the first connecting plate 122 and the longitudinal beam body 11 is a curve. This arrangement ensures that the first weld 6 formed between the first connecting plate 122 and the longitudinal beam body 11 is located on the side of the longitudinal beam body 11 away from the other vehicle body longitudinal beam 1, resulting in a larger length of the first weld 6. This strengthens the connection between the first connecting plate 122 and the corresponding longitudinal beam body 11, thereby increasing the connection strength between the connecting part 12 and the corresponding longitudinal beam body 11. Furthermore, by ensuring that the curvature of the first weld 6 in the height direction of the vehicle assembly is greater than 0, i.e., in the length direction of the vehicle assembly, the first weld 6 is a curved weld rather than a straight weld, the force at the first weld 6 can be decomposed in different directions when the vehicle is subjected to forces in the front-rear direction, thereby increasing the strength of the first weld 6 and further enhancing the connection strength between the connecting part 12 and the corresponding longitudinal beam body 11.

[0053] It should be noted that the length direction of the frame assembly is consistent with the x-axis direction in the above description; the height direction of the frame assembly is consistent with the z-axis direction in the above description. Figure 1 Figure 1

[0054] In some optional embodiments, in order to limit the position of the thrust rod 2, the side of the reinforcing part 121 facing the second extension part 32 is provided with a limiting protrusion 1211 protruding towards the second extension part 32 along the width direction of the frame assembly. In this way, the position of the thrust rod 2 can be limited, and the connection reliability between the thrust rod 2, the first support 3 and the connecting part 12 can be improved.

[0055] As shown in Figures 1 to 4 , in order to make the vehicle have a certain stability during driving, the frame assembly provided by the embodiment further comprises a transverse stabilizer 7, for example, a rear transverse stabilizer. Each connecting part 12 is connected with a second support 8 which is spaced apart from the first support 3. It should be noted that the spaced apart herein can be understood as that the surface of the first support 3 is not in contact with the surface of the second support 8. The two ends of the transverse stabilizer 7 are respectively connected to the second support 8 on the corresponding side of the body longitudinal beam 1. In this way, the second support 8 and the first support 3 are both connected to the connecting part 12, so that the body longitudinal beam 1 can absorb the force received by the thrust rod 2, and the connection between the thrust rod 2 and the body longitudinal beam 1 can avoid interfering with other components to a certain extent.

[0056] Please continue to refer to Figure 9 , Figure 9 the connection structure between the connecting part and the second support in the frame assembly provided by the embodiment of the application. In some embodiments, the first connecting plate 122 and the second connecting plate 123 are welded together, and the intersection of the first connecting plate 122 and the second connecting plate 123 forms a second weld 9. The second support 8 surrounds at least part of the second weld 9. In this way, by surrounding at least part of the second weld 9 with the second support 8, the force received by the connecting part 12 will not directly act on the second weld 9, thereby improving the fatigue resistance of the body longitudinal beam 1 after the body longitudinal beam 1 is connected with the first support 3 and the second support 8.

[0057] ​​In some embodiments, the second support 8 described above comprises a third connecting plate 81 and a fourth connecting plate 82 which are buckled to each other along the width direction of the frame assembly and are welded together, wherein the third connecting plate 81 is located on the same side as the first connecting plate 122, the fourth connecting plate 82 is located on the same side as the second connecting plate 123, and in order to install the transverse stabilizer 7, an installation gap 83 should be provided between the third connecting plate 81 and the fourth connecting plate 82, for example, the end of the transverse stabilizer 7 is connected with the fourth connecting plate 82 through a threaded fastener, at this time, during installation, the operator needs to enter between the third connecting plate 81 and the fourth connecting plate 82 through the installation gap 83 to connect the end of the transverse stabilizer 7 with the fourth connecting plate 82.

[0058] The frame assembly provided by the embodiment comprises two body side members and a thrust rod. Each body side member is connected with a first support, and a mounting space with a socket is formed between the first support and the corresponding body side member, and the direction of the socket is consistent with the extension direction of the body side member. One end of the thrust rod is inserted into the mounting space through the socket and connected with the first support to be connected with the corresponding body side member, and the other end of the thrust rod is used to be connected with the rear axle. In the frame assembly provided by the embodiment, the thrust rod is connected between the body side member and the rear axle, and the extension direction of the thrust rod is consistent with the extension direction of the body side member. In this way, when the vehicle is subjected to a force in the front-rear direction, the force on the thrust rod will be more absorbed by the body side member, so that the thrust rod can be prevented from being damaged and disabled to a certain extent, and the stability of the vehicle during driving can be improved.

[0059] The embodiment also provides a vehicle comprising the frame assembly in the above-mentioned embodiments. The frame assembly has been described in detail in the above-mentioned embodiments, and will not be described here.

[0060] It should be noted that the vehicle provided by the embodiment should also comprise other modules or components that can enable the vehicle to operate normally, which will not be described here.

In the embodiment, the thrust rod is connected between the body side member and the rear axle, and the extension direction of the thrust rod is consistent with the extension direction of the body side member. In this way, when the vehicle is subjected to a force in the front-rear direction, the force on the thrust rod is more absorbed by the body side member, so that the thrust rod can be prevented from being damaged and disabled to a certain extent, and the stability of the vehicle during driving can be improved.
