[0034] In addition, those of ordinary skill in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0035] Unless the context clearly requires otherwise, the words "including", "comprising", and similar words in the entire 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] The present application provides a vehicle frame and a vehicle provided with the vehicle frame, as Figure 1 shown. The vehicle frame includes a vehicle frame main body 1 and a rear suspension lower thrust rod connection structure 2. The connection structure 2 includes a rear suspension lower thrust rod seat 41 connecting plate 3 and a thrust rod seat 41. The connecting plate 3 is connected to the vehicle frame main body 1 of the vehicle, as Figure 1 and 4 shown. The cross-section of the connecting plate 3 of the rear suspension lower thrust rod seat 41 in the present application is in a "Z" shape, including an upper connecting portion 31, an intermediate connecting portion 32, and a lower connecting portion 33 (in order to clearly show the specific structure of the lower thrust rod connection structure 2, the vehicle frame in the attached Figure 1 is in an inverted state, that is, the upper-lower position in the working state is the lower-upper shown in the attached Figure 1 , and the attached Figure 2 is the same as the attached Figure 1 , also in an inverted state). Among them, the upper connecting portion 31 and the lower connecting portion 33 are horizontally connected to the vehicle frame main body 1, the intermediate connecting portion 32 is substantially vertically connected to the vehicle frame main body 1, the thrust rod seat 41 is provided on the intermediate connecting portion 32 and is connected to one end of the thrust rod. The connection between the upper connecting portion 31 and the lower connecting portion 33 and the vehicle frame main body 1 provides support for the connecting plate 3 in the vertical direction, the intermediate connecting portion 32 provides support for the connecting plate 3 in the horizontal direction, and the upper connecting portion 31, the intermediate connecting portion 32, and the lower connecting portion 33 cooperate with the vehicle frame main body 1 to provide effective support and connection for the thrust rod seat 41. When the vehicle is running, the force received by the thrust rod is better transmitted to the vehicle frame main body 1 through the connecting plate 3, improving the stability of the thrust rod and the thrust rod seat 41, ensuring that the thrust rod connected thereto can work stably, and thus ensuring the normal use of the vehicle.

[0038] As Figure 2As shown, in a preferred embodiment, a support member 42 is provided on the intermediate connecting portion 32. The support member 42 is disposed horizontally and is used to support the thrust rod seat 41. The two thrust rod seats 41 are spaced apart on the support member 42, preferably disposed at the two ends of the support member 42. The fixed connection between the thrust rod seat 41 and the support member 42 forms the vehicle rear suspension lower thrust rod connection seat assembly 4 in this application, making the overall structural layout of the lower thrust rod connection seat assembly 4 more reasonable, the force more evenly distributed, and the overall structural strength better. As Figure 1 shown, during assembly, before the overall welding of the frame body 1, the lower thrust rod connection seat assembly 4 can be assembled first, that is, the thrust rod seat 41 and the support member 42 can be assembled first. Compared with directly assembling the thrust rod seat 41 to the frame body 1 originally, the lower thrust rod connection seat assembly 4 in this application can effectively strengthen the connection strength and bearing capacity of the thrust rod seat 41, and is more convenient for the positioning of the thrust rod. First, the two thrust rod seats 41 are set on the support member 42 to form a lower thrust connection seat assembly and then connected to the frame body 1. Compared with the previous connection of the two thrust rod seats 41 to the frame body 1 separately, the positioning dimension of the thrust rod seat 41 in this application is more accurate. Moreover, when the lower thrust connection seat assembly is integrally connected and fixed to the frame body 1, the positioning dimension is more convenient to adjust, greatly improving the coaxiality between the thrust rod and the frame body 1 and enhancing the connection strength between the thrust rod and the frame body 1. In addition, the thrust rod seat 41 and the support member 42 form the lower thrust rod connection seat assembly 4, and then it is connected and fixed to the connecting plate 3, which can further enhance the connection strength and stability of the thrust rod seat 41 and ensure the stable operation of the vehicle.

[0039] Preferably, as Figure 2As shown, the cross-section of the support member 42 is in the shape of ┏, including a support plate 421 and a support plate connection plate 4223. The thrust rod seat 41 is disposed inside the ┏-shaped plate to ensure the connection stability between the thrust rod seat 41 and the support member 42. Preferably, the upper end of the thrust rod seat 41 is connected to the lower surface of the support member 42. One surface of the support plate connection plate 4223 is connected to the intermediate connection portion 32, and the side portion of the thrust rod seat 41 is connected to the other surface of the support plate connection plate 4223. The connection between the thrust rod seat 41 and the support member 42 forms a ┏-shaped connection, which better ensures the force transmission between the thrust rod seat 41 and the support member 42 and guarantees the connection stability. By connecting one surface of the support plate connection plate 4223 to the intermediate connection portion 32, the force of the thrust rod can be effectively transmitted to the intermediate connection portion 32 of the connection plate 3, and then through the upper connection portion 31 and the lower connection portion 33, the force is transmitted to the vehicle frame main body 1, so that the thrust rod seat 41 bears the force better and has stronger stability. More preferably, the support plate connection plate 4223 and the support plate 421 are of an integral structure, which further ensures the connection strength between the support plate 421 and the support plate connection plate 4223, thereby ensuring the overall structural strength of the lower thrust rod connection seat assembly 4 and improving the overall performance.

[0040] In a preferred embodiment, as Figure 2 shown, a through groove 4211 is provided on the support plate 421. Each thrust rod seat 41 includes a first connection portion 411 and a second connection portion 412 that are oppositely arranged. The thrust rod seat 41 is configured such that in the vehicle width direction, the first connection portion 411 and the second connection portion 412 are oppositely arranged at a predetermined distance to ensure the connection stability between each thrust rod seat 41 and the support plate 421 of the support member 42. The through groove 4211 is provided between the first connection portion 411 and the second connection portion 412 to provide space for the installation and movement of the thrust rod to ensure the correct installation and use of the thrust rod.

[0041] As Figure 2 and 4As shown, in a preferred embodiment, a reinforcing structure 5 is provided between the support plate connecting plate 4223 and the support plate 421, and between the support plate 421 and the upper connecting portion 31, further strengthening the overall structural strength of the support member 42 and the connection strength between the support member 42 and the connecting plate 3, strengthening the overall structural strength and stability of the lower thrust rod connection seat assembly 4 and the connecting plate 3. In the vehicle width direction, the reinforcing structure 5 is provided between the two thrust rod seats 41, with a reasonable structural layout, strengthening the connection strength between the support plate 421 and the support plate connecting plate 4223, and ensuring the overall stability of the support member 42. The reinforcing structure 5 between the support plate 421 and the upper connecting portion 31 is provided on the upper side of the support plate 421 and is called the upper reinforcing structure 51. The upper reinforcing structure 51 is connected between the upper connecting portion 31 and the upper surface of the support plate 421. The reinforcing structure 5 between the support plate connecting plate 4223 and the support plate 421 is provided on the lower side of the support plate 421 and is called the lower reinforcing structure 52. The lower reinforcing structure 52 is connected between the other surface of the support plate connecting plate 4223 and the lower surface of the support plate 421, rationally utilizing the space between the structures, strengthening the overall stability and structural strength of the connection structure 2, and improving the overall stability of the frame body 1.

[0042] Specifically, as Figure 2 shown, the reinforcing structure 5 includes reinforcing plates, including an upper reinforcing plate 511 belonging to the upper reinforcing structure 51 and a lower reinforcing plate 521 belonging to the lower reinforcing structure 52. Preferably, both the upper reinforcing plate 511 and the lower reinforcing plate 521 are vertically arranged. The lower reinforcing plate 521 is configured as a generally triangular plate, preferably a right triangle. One end face of a right side of the triangular plate is connected to the support plate 421, and the other end face of the right side of the triangular plate is connected to the support plate connecting plate 4223, which can effectively ensure the close contact between the two end faces of the lower reinforcing plate 521 and the support plate connecting plate 4223 and the support plate 421, ensure the welding quality, avoid welding defects, and the triangular lower reinforcing plate 521 is better stressed, which can ensure better overall structural strength and stability of the lower thrust rod connection seat assembly. The upper reinforcing plate 511 is configured as a generally square shape. Three end faces of the square upper reinforcing plate 511 are welded and fixed to the support plate 421, the middle connecting portion 32 of the connecting plate 3, and the upper connecting portion 31 respectively, to strengthen the connection strength between the support member 42 and the connecting plate 3, thereby further ensuring the overall structural strength and stability of the lower thrust rod connection seat assembly 4 and the connecting plate 3.

[0043] Preferably, as Figure 2 and 4As shown, a plurality of upper reinforcing plates 511 are provided. The plurality of upper reinforcing plates 511 are arranged at intervals with a reasonable layout, and the strengthening effect is better. A third through hole 321 is provided on the middle connecting portion between the upper reinforcing plates 511. The third through hole 321 is close to the upper connecting portion 31. The third through hole 321 is an elongated hole and extends in the width direction of the vehicle. The setting of the third through hole 321 makes the force conduction of the overall structure of the middle connecting portion 32 more uniform and stable. On the other hand, it is also more conducive to the welding connection between the middle connecting portion 32 of the connecting plate 3 and the vehicle frame main body 1, enabling faster heat dissipation during welding and avoiding welding defects caused by poor heat dissipation. In addition, the setting of the third through hole 321 is also more conducive to heat dissipation during the vehicle's driving, avoiding damage to the vehicle frame main body 1 caused by poor heat dissipation and extending the service life of the vehicle. More preferably, a plurality of lower reinforcing plates 521 are provided. The plurality of lower reinforcing plates 521 are arranged at intervals. A fourth through hole 4221 is provided on the support plate connecting plate 4223 between the lower reinforcing plates 521.

The two side plates 6 are arranged at both ends of the support member 42 in the width direction of the vehicle. Each of the opposite surfaces of the two side plates 6 is simultaneously connected to the support plate 421 and the support plate connecting plate 4223, further strengthening the overall structural strength of the support member 42. Preferably, the structure of the side plate 6 is generally a right triangle, and the end faces of the two right-angled sides of each side plate 6 are respectively welded to the upper connecting portion 31 and the middle connecting portion 32 of the connecting plate 3, further strengthening the overall structural strength and stability of the connection structure 2.

[0045] In a preferred embodiment, as Figure 2As shown, the upper connecting portion 31 includes an upper crossbeam connecting portion 311 and an upper longitudinal beam connecting portion 312. The upper longitudinal beam connecting portion 312 is disposed at the end of the upper crossbeam connecting portion 311 and is located on both sides close to the upper crossbeam connecting portion 311. The middle part of the upper crossbeam connecting portion 311 is connected to the upper crossbeam, and the two side parts cooperate with the upper longitudinal beam connecting portion 312 to jointly connect to the upper longitudinal beam, making the connection layout between the upper connecting portion 31 and the vehicle frame main body 1 more reasonable and ensuring the connection strength and stability. Preferably, the upper longitudinal beam connecting portion 312 is smoothly transitioned to the upper crossbeam connecting portion 311 to ensure the overall structural stability and structural strength of the upper connecting portion 31. More preferably, a first through hole 313 is provided on the upper crossbeam connecting portion 311 and / or the upper longitudinal beam connecting portion 312. The first through hole 313 provided on the upper crossbeam connecting portion 311 is a round hole, and the first through hole 313 provided on the upper longitudinal beam connecting portion 312 is an elongated hole. The extending direction of the elongated hole is the length direction of the vehicle. The round hole and the elongated hole can, on the one hand, reduce the overall weight of the vehicle frame main body 1, and on the other hand, facilitate welding connection, avoid welding defects, and ensure welding strength.
