Detailed implementation manners

[0034] The present invention will be described below based on embodiments, but the present invention is not limited to these embodiments. Those of ordinary skill in the art should understand that the drawings provided herein are for illustrative purposes only, and the drawings are not necessarily drawn to scale.

[0035] Unless the context clearly requires otherwise, the words "including", "comprising" and similar words throughout the specification and claims should be construed in an inclusive sense rather than an exclusive or exhaustive sense; that is, the meaning of "including but not limited to".

[0036] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0037] This application provides a vehicle frame, as Figure 1 、 3 、shown in Figure 5, which includes a plurality of connected frame unit assemblies 100. The frame unit assemblies 100 are connected by a connection structure. In this way, during assembly, each frame unit assembly 100 can be assembled separately first, and then the separately assembled frame unit assemblies 100 can be assembled into the entire frame through the connection structure, thereby greatly improving the assembly efficiency of the frame. In addition, when improving the structure of each frame unit assembly 100, as long as the connection structure is not changed, the installation between parts will not be affected, thereby greatly improving the development efficiency of the frame structure.

[0038] Furthermore, the connection structure includes end connection frames 200 respectively arranged at the ends of two frame unit components 100. The end connection frames 200 of the two frame unit components 100 are fixedly connected. Since the connection between the frame unit components 100 is realized by using a frame structure, the structural reliability of the assembled frame is greatly improved, and thus the load capacity of the frame is improved.

[0039] Further preferably, the planes where the end connection frames 200 of the two connected frame unit components 100 are located are parallel to each other, thereby greatly increasing the contact area between the end connection frames 200, and further improving the structural reliability of the assembled frame.

[0040] The division of the frame unit components 100 can be set according to the specific frame structure and requirements. For example, in Figure 1 、 3 In the embodiment shown in FIG. 5, the multiple frame unit components 100 include a front section frame 1, a middle section frame 2, and a rear section frame 3 that are sequentially connected by a connection structure from front to back. The end connection frames 200 include a first frame 4 arranged at the rear end of the front section frame 1, a second frame 5 and a third frame 6 respectively arranged at the front and rear ends of the middle section frame 2, and a fourth frame 7 arranged at the front end of the rear section frame 3.

[0041] The structures of the respective end connection frames 200 can be the same or different. For the convenience of processing and standardized production, preferably, the structures of the respective end connection frames 200 are the same. Specifically, as Figure 7 shown, the end connection frame 200 includes an outer frame 210 and an intermediate beam 220 arranged inside the outer frame 210. The outer frame 210 can be a polygon shape such as a rectangle, a trapezoid, a combination of a rectangle and a trapezoid, a combination of multiple trapezoids, etc. The intermediate beam 220 includes an intermediate cross beam, an intermediate vertical beam, and / or an intermediate diagonal beam. In a specific embodiment, as Figure 7 shown, a plurality of intermediate vertical beams are arranged at intervals along the width direction of the frame.

[0042] To improve the structural strength of the end connection frame 200, preferably, the outer frame 210 includes at least one arc beam 2122. Specifically, the outer frame 210 includes an upper cross beam 211, a lower cross beam 212, and connection beams 213 respectively connecting the two ends of the upper cross beam 211 and the lower cross beam 212. The two ends of the intermediate vertical beam are respectively connected to the upper cross beam 211 and the lower cross beam 212. The arc beam 2122 is arranged on the lower cross beam 212. Further preferably, the lower cross beam 212 includes a straight beam 2121, and the arc beams 2122 are respectively arranged at the two ends of the straight beam 2121, and, in the direction from the middle of the straight beam 2121 to the two ends, the arc beams 2122 are bent towards the direction close to the upper cross beam 211.

[0043] Specifically, as Figure 1 andFigure 2 As shown in the figure, the front section of the frame 1 includes a front wheel fender 11. The first frame 4 is disposed at the rear end of the front wheel fender 11 and fixedly connected to the front wheel fender 11. Specifically, the front wheel fender 11 includes a side plate 111 and an enclosing plate 112 connected to the side plate 111. The enclosing plate 112 is used to enclose the wheel along the circumferential direction of the wheel. The enclosing plate 112 includes two vertical plates 1121 extending in the vertical direction and an arc plate 1122 connecting the tops of the two vertical plates 1121. The two vertical plates 1121 are spaced apart from each other in the length direction of the frame. The first frame 4 is parallel to the rear vertical plate 1121 and connected to the rear vertical plate 1121.

[0044] The middle section of the frame 2 is the standing area of the vehicle and is used for bearing weight. The middle section of the frame 2 is generally a frame structure formed by the intersection of a plurality of cross beams, a plurality of longitudinal beams, and a plurality of diagonal beams extending in the horizontal direction. Further preferably, a plurality of frame structures 21 are also provided on the middle section of the frame 2, and the frame structure 21 has the same structure as the end connection frame 200. Preferably, the cross beams of the middle section of the frame 2 form a part of the frame structure 21. In this way, the structural strength of the middle section of the frame 2 can be improved, and further, the structural reliability and load-carrying capacity of the vehicle can be improved.

[0045] As Figures 3 to 6 shown in the figure, the rear section of the frame 3 includes an airbag rear wheel mounting assembly. The fourth frame 7 is disposed at the front end of the airbag rear wheel mounting assembly and fixedly connected to the airbag rear wheel mounting assembly. Specifically, the airbag rear wheel mounting assembly includes a rear bracket 31, an airbag mounting structure 32 provided on the rear bracket 31, a diagonal brace 33, and a lower thrust rod connection assembly 34. Among them, the top end of the fourth frame 7 is fixedly connected to the rear bracket 31. Specifically, the top surface of the upper cross beam of the fourth frame 7 is connected to the cross beam of the rear bracket 31. The rear side surface of the upper cross beam of the fourth frame 7 is fixedly connected to the diagonal brace 33. The lower cross beam and / or the connecting beam of the fourth frame 7 is fixedly connected to the lower thrust rod connection assembly 34. Further specifically, as Figure 6 shown in the figure, the lower thrust rod connection assembly 34 includes a first connecting plate 341 having a cross section in the shape of a "Z" and a thrust rod seat 342. The first connecting plate 341 includes an upper connecting portion 3411, an intermediate connecting portion 3412, and a lower connecting portion 3413. The thrust rod seat 342 is connected to the rear side surface of the intermediate connecting portion 3412. The upper connecting portion 3411 is connected to the diagonal brace 33. The bottom surface of the lower cross beam of the fourth frame 7 abuts against the lower connecting portion 3413, thereby improving the connection strength between various parts. Further preferably, the lower connecting portion 3413 extends further forward so that the bottom surface of the lower cross beam of the third frame 6 abuts against the lower connecting portion 3413, thereby further improving the support strength for the middle section of the frame 2.

[0046] Further, the lower thrust connection assembly 34 further includes a second connecting plate 343 located between the intermediate connecting portion 3412 and the fourth frame 7. The front side surface of the second connecting plate 343 is connected to the lower cross beam and the connecting beam of the fourth frame 7, and the rear side surface of the second connecting plate 343 is connected to the intermediate connecting portion 3412. Preferably, a plurality of connecting beams of the fourth frame 7 are arranged along the width direction of the vehicle frame, and a plurality of second connecting plates 343 are correspondingly arranged corresponding to the connecting beams of the fourth frame 7. The second connecting plate 343 is used to fill the gap between the fourth frame 7 and the first connecting plate 341. In this way, the weight of the entire lower thrust connection assembly 34 can be effectively reduced, making the overall structure more reliable.

[0047] The vehicle frame provided by the present invention is divided into a plurality of frame unit components 100. The frame unit components 100 are connected through a connection structure. During assembly, each frame unit component 100 can be assembled separately first, and then the separately assembled frame unit components 100 are assembled into the entire vehicle frame through the connection structure, thereby greatly improving the assembly efficiency of the vehicle frame. In addition, the frame unit components 100 are connected through an end connection frame 200, which greatly improves the structural reliability of the assembled vehicle frame and the load capacity of the vehicle frame.

[0048] Further, the present application also provides a vehicle, especially an electric bus, which includes the vehicle frame as described above.
