[0029] 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 understood 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.

[0030] The present application provides a rear suspension lower thrust rod seat connecting plate, a frame and a vehicle, as Figure 1 shown. The frame includes a frame main body 1 and a rear suspension lower thrust rod connecting structure 2. The connecting 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 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 part 31, an intermediate connecting part 32 and a lower connecting part 33. (In order to clearly show the specific structure of the lower thrust rod connecting structure 2, the frame in the Figure 1 figure is in an inverted state, that is, the upper-lower position in the working state is shown as lower-upper in the Figure 1 figure, the Figure 2 and the Figure 1The same, also in an inverted state), wherein the upper connecting portion 31 and the lower connecting portion 33 are horizontally connected to the vehicle frame main body 1, the middle connecting portion 32 is substantially vertically connected to the vehicle frame main body 1, the thrust rod seat 41 is arranged on the middle connecting portion 32 and 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 vertical support for the connecting plate 3, and the middle connecting portion 32 provides horizontal support for the connecting plate 3. The upper connecting portion 31, the middle connecting portion 32, the lower connecting portion 33 and the vehicle frame main body 1 cooperate with each other 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 connected thrust rod can work stably, and thus guaranteeing the normal use of the vehicle.

[0031] As Figure 2 shown, in a preferred embodiment, a support member 42 is arranged on the middle connecting portion 32. The support member 42 is horizontally arranged and is used to support the thrust rod seat 41. The two thrust rod seats 41 are arranged at intervals on the support member 42, preferably 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 distribution more uniform, and the overall structural strength better. As Figure 1 shown, during assembly, before the overall welding of the vehicle frame main 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 onto the vehicle frame main body 1 originally, the lower thrust rod connection seat assembly 4 in this application can effectively enhance 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 arranged on the support member 42 to form a lower thrust connection seat assembly and connected to the vehicle frame main body 1. Compared with the previous connection of the two thrust rod seats 41 to the vehicle frame main 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 vehicle frame main body 1, the positioning dimension is more convenient to adjust, greatly improving the coaxiality between the thrust rod and the vehicle frame main body 1 and enhancing the connection strength between the thrust rod and the vehicle frame main 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, ensuring the stable operation of the vehicle.

[0032] 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 connecting 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 connecting plate 4223 is connected to the intermediate connecting portion 32, and the side portion of the thrust rod seat 41 is connected to the other surface of the support plate connecting 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 connecting plate 4223 to the intermediate connecting portion 32, the force of the thrust rod can be effectively transmitted to the intermediate connecting portion 32 of the connecting plate 3, and then through the upper connecting portion 31 and the lower connecting 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 connecting 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 connecting plate 4223, thus ensuring the overall structural strength of the lower thrust rod connecting seat assembly 4 and improving the overall performance.

[0033] 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 connecting portion 411 and a second connecting portion 412 which are oppositely arranged. The thrust rod seat 41 is configured such that in the vehicle width direction, the first connecting portion 411 and the second connecting 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 connecting portion 411 and the second connecting 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.

[0034] As Figure 2 and 4 shown, in a preferred embodiment, a strengthening structure 5 is provided between the support plate connecting plate 4223 and the support plate 421 to further strengthen the overall structural strength of the support member 42 and enhance the overall structural strength and stability between the lower thrust rod connecting seat assembly 4 and the connecting plate 3. In the vehicle width direction, the strengthening structure 5 is provided between the two thrust rod seats 41, with a reasonable structural layout, which strengthens the connection strength between the support plate 421 and the support plate connecting plate 4223 and ensures the overall stability of the support member 42. The strengthening structure 5 is located between the support plate connecting plate 4223 and the support plate 421 and is provided on the lower side of the support plate 421, making rational use of the space between the structures, strengthening the overall stability and structural strength of the connection structure 2, and improving the overall stability of the vehicle frame main body 1.

[0035] Specifically, as Figure 2 shown, the reinforcing structure 5 includes a reinforcing plate 51. Preferably, the reinforcing plate 51 is vertically arranged. The reinforcing plate 51 is configured as a substantially triangular plate, preferably a right triangle. One end face of a right-angle side of the triangular plate is connected to the support plate 421, and the other end face of the other right-angle 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 reinforcing plate 51 and the support plate connecting plate 4223 and the support plate 421, ensure the welding quality, avoid welding defects, and the triangular reinforcing plate 51 is better stressed, which can ensure better overall structural strength and stability of the lower push rod connecting seat assembly.

[0036] Preferably, as Figure 2 and 4 shown, a plurality of reinforcing plates 51 are provided. A plurality of upper reinforcing plates 511 are arranged at intervals with a reasonable layout, and the reinforcing effect is better. A through hole 4221 is provided on the support plate connecting plate 4223 between the reinforcing plates 51. The through hole 4221 is an elongated hole and extends in the vehicle width direction to achieve a better reinforcing effect, and the through hole 4221 enables faster heat dissipation during welding, avoiding welding defects caused by poor heat dissipation, and further ensuring the overall structural strength and stability of the connection structure 2.

[0037] As Figure 2 shown, in a preferred embodiment, two side plates 6 are further provided on the support member 42. The two side plates 6 are arranged at both ends of the support member 42 in the vehicle width direction. 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 side plate 6 is configured as a substantially right triangle, and the end faces of the two right-angle sides of each side plate 6 are respectively welded and connected 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.

[0038] In a preferred embodiment, as Figure 2 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 arranged at the end of the upper crossbeam connecting portion 311 and is located at positions close to both sides of 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 frame main body 1 more reasonable, ensuring the strength and stability of the connection. 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 strength of the upper connecting portion 31.

[0039] As Figure 2 and 4 shown, more preferably, the lower connecting portion 33 includes a lower crossbeam connecting portion 331 and a lower longitudinal beam connecting portion 332. The lower longitudinal beam connecting portion 332 is arranged at the end of the lower crossbeam connecting portion 331 and is located at positions close to both sides of the lower crossbeam connecting portion 331. The structural layout is reasonable to ensure the stability of the connection. Preferably, the lower longitudinal beam connecting portion 332 is smoothly transitioned to the lower crossbeam connecting portion 331 to ensure the overall structural strength and stability of the lower connecting portion 33.

[0040] In a preferred embodiment, as Figure 1 and 3 shown, between the middle connecting portion 32 of the connecting plate 3 and the vehicle frame main body 1, a connecting member 6 for connecting the connecting plate 3 is provided. The connecting member 6 is vertically arranged, is connected to the middle connecting portion 32, and extends along the width direction of the middle connecting portion 32. The connecting member 6 is provided with an oblique cutting structure at the bent portion of the middle connecting portion 32 and the lower connecting portion 33 to ensure the close contact of the connecting member 6 with this portion and guarantee the connection strength. The connecting member 6 plays a certain supporting and strengthening role in the connection between the connecting plate 3 and the vehicle frame main body 1 to ensure the overall structural strength and stability of the connection between the "Z"-shaped connecting plate 3 and the vehicle frame main body 1.

[0041] During assembly, as Figure 1 shown, first, the thrust rod seat 41 is connected to the support member 42 to form the rear suspension lower thrust rod connecting seat assembly 4, which is mainly used for connecting and fixing the thrust rod. Then, the rear suspension lower thrust rod connecting seat assembly 4 is fixedly connected to the connecting plate 3, and finally, the connecting plate 3 is fixedly connected to the vehicle frame main body 1. This kind of connection and fixing method replaces the traditional connection method of directly welding the thrust rod seat 41 to the vehicle frame main body 1. The structure in the present application is more convenient for the positioning of the thrust rod seat 41, and through the support member 42, the connecting plate 3, and the strengthening structure 5, etc., the connection strength and stability between the thrust rod seat 41 and the vehicle frame main body 1 can be effectively guaranteed, which is more beneficial to ensuring the coaxiality of the thrust rod and the vehicle frame main body 1, ensuring the overall structural strength and stability of the vehicle, guaranteeing the normal driving of the vehicle, and extending the service life.
