Description

Technical Field

[0001] This invention relates to the field of vehicles, and more particularly to a subframe and a vehicle. Background Technology

[0002] As part of the core structure of the vehicle chassis, the subframe provides a robust, precise, and stable mounting base for all key components of the rear suspension system, such as toe bars, steering knuckles, stabilizer bars, and spring arms. It connects the dispersed suspension hardpoints into a unified whole, greatly enhancing the torsional and bending stiffness of the rear underbody of the vehicle.

[0003] However, current subframe structure designs still suffer from problems such as poor rigidity, strength, and collision performance. Designing a subframe with good rigidity and strength has become a challenge. Summary of the Invention

[0004] This invention provides a subframe and a vehicle, which solves the technical problem of how to improve the stiffness performance of the subframe without increasing its weight.

[0006] In some embodiments, the suspension structure includes: two rear suspension structures, which are spaced apart along the central axis of the rear suspension structures, and the top of each rear suspension structure has the mounting plate; wherein, there are two mounting posts, which are spaced apart along the central axis of the rear suspension structures; and two toe-in mounting structures, each with a toe-in mounting rod disposed on one of the two mounting posts and connected to the mounting plates of the two rear suspension structures.

[0007] In some embodiments, the suspension structure further includes a support structure that extends from the top of the suspension structure and is fixedly connected to the side of the mounting plate facing away from the mounting column.

[0008] In some embodiments, the subframe further includes: spring arm mounting structures, two of which are respectively disposed on the two mounting columns and are both located above the toe-in mounting structure and the mounting plate.

[0009] In some embodiments, the subframe further includes a mounting beam, the two ends of which are fixedly connected to two spaced-apart mounting columns.

[0010] In some embodiments, the subframe further includes a subframe mounting structure disposed on the subframe body; wherein a reinforcing structure is provided between the suspension structure and the subframe mounting structure.

[0011] In some embodiments, a stabilizer bar mounting structure is provided on the outer surface of the subframe mounting structure.

[0012] In some embodiments, the subframe further includes a roll bar mounting structure extending from the outer surface of the subframe body, and the roll bar mounting structure and the subframe body have an arc transition surface.

[0013] In some embodiments, the suspension structure further includes: a front suspension structure extending from the subframe body, and the front suspension structure being located on one side of the line connecting the geometric center points of the two rear suspension structures; wherein the roll bar mounting structure is located between the front suspension structure and the rear suspension structure, and the roll bar mounting structure is located on the side closer to the rear suspension structure.

[0014] A second aspect of the present invention provides a vehicle comprising: a subframe as provided in the first aspect of the preceding embodiments; a drive motor fixedly connected to the suspension structure; and a toe bar connected to the subframe via the toe bar mounting structure, wherein the toe bar is clamped between the mounting plate and the mounting column.

[0015] This invention provides a subframe comprising a subframe body, a plurality of suspension structures protruding from the subframe body, a mounting post protruding from the subframe body and located on the same side of the subframe body as the suspension structures, and a toe-in mounting structure disposed on the mounting post. The suspension structures have a mounting plate at their top, and the toe-in can be clamped between the mounting post and the mounting plate. That is, in the toe-in mounted state, the suspension structure with the mounting plate and the mounting post can support each other, thereby improving the structural rigidity of the subframe. This increase in structural rigidity is not achieved by adding material, thus not increasing the weight of the subframe. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] The specific technical features described in the various embodiments in the detailed implementation can be combined in various ways without contradiction. For example, different implementation methods can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

[0020] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0021] Additionally, it should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate any similarity or connection between them. It should be understood that the directional descriptions such as "above," "below," "inside," and "outside" refer to the orientation under normal use conditions.

[0022] The subframe can be considered the skeleton of the front and rear axles, and is a component of the front and rear axles. The subframe is not a complete frame; it is merely a support structure that holds the front and rear axles and suspension, allowing the axles and suspension to connect to the "main frame" via it. It is conventionally called a "subframe." The function of the subframe is to isolate vibration and noise, reducing their direct entry into the passenger compartment. In the following specific embodiments, the drive motor or engine is also mounted on the subframe via a suspension structure. This subframe can be mounted at the front of the frame to form the front frame, or it can be mounted at the rear of the frame to form the rear frame. The structure and function of this subframe will be illustrated below with reference to various embodiments.

[0023] In some embodiments, such as Figure 1As shown, the subframe 10 includes: a subframe body 100, a suspension structure 200, a mounting column 300, and a toe-in mounting structure 400. Multiple suspension structures 200 protrude from the subframe body 100. These multiple suspension structures 200 allow the engine or drive motor to be mounted on the subframe 10. The bottom of the engine or drive motor is higher than the subframe body 100, and each suspension structure 200 has an elastic damping structure. During operation, the engine or drive motor will not directly collide with the subframe body 100, and its vibrations will be transmitted to the subframe body 100 through the elastic damping structure of the suspension structure 200, thus isolating the engine or drive motor vibrations from the subframe body 100 to a certain extent. A mounting post 300 protrudes from the subframe body 100, and the mounting post 300 and the suspension structures 200 are located on the same side of the subframe body 100. A toe-in mounting structure 400 is disposed on the mounting post 300. At least a portion of the suspension structures 200 has a mounting plate 210 on its top. The mounting post 300, which protrudes from the subframe body 100, provides a mounting position for the toe-in mounting structure 400, allowing it to be positioned above the suspension structure 200 and close to the top of the mounting plate 210. The distance between the mounting post 300 and the mounting plate 210 is determined by the thickness of the toe-in to be installed. The toe-in toe can be mounted on the subframe 10 via the toe-in mounting structure 400. With the toe-in mounted on the subframe 10, the toe-in can be clamped between the mounting plate 210 and the mounting post 300. In this state, the mounting plate 210 and the mounting post 300 of the suspension structure 200 can support each other. This mutual support structure improves the overall structural rigidity of the suspension structure 200 and the mounting post 300 without increasing the material, thus eliminating the need to increase the weight of the subframe 10.

[0024] The toe bar is used to adjust the wheel toe angle. Depending on the position of the subframe 10, this toe angle can be either the front wheel toe angle or the rear wheel toe angle. It should be noted that the toe bar mounting structure 400 can install the toe bar onto the subframe 10 in any way, clamping the toe bar between the mounting post 300 and the mounting plate 210. For example, the toe bar mounting structure 400 is a claw structure, which includes a fixed claw, a sliding plate, and a movable claw. The fixed claw is fixed to the mounting plate 210. The sliding plate is fixedly connected to the fixed claw and extends from the side of the mounting plate 210 near the mounting post 300 to the side away from the mounting post 300. The movable claw is slidably connected to the sliding plate and can move closer to or away from the mounting plate 210. After the toe bar is installed on the mounting post 300 and the mounting plate 210, the movable claw moves closer to the mounting plate 210. Sliding in the direction of 0 allows the mounting plate 210 to undergo elastic deformation close to the mounting post 300, thereby clamping the toe bar between the mounting post 300 and the mounting plate 210. For example, the toe bar mounting structure includes a mounting screw and a mounting nut. The mounting plate 210 has a mounting through hole. One end of the mounting screw is fixed to the mounting post 300, and the other end passes through the mounting through hole of the mounting plate 210. After the toe bar is positioned between the mounting post 300 and the mounting plate 210 (by setting the position or using a clearance groove on the toe bar to prevent interference between the toe bar and the mounting screw), the mounting nut is fitted onto the mounting screw and rotated to press the mounting nut against the mounting plate 210, causing the mounting plate 210 to undergo elastic deformation close to the mounting post 300, thereby clamping the toe bar between the mounting post 300 and the mounting plate 210.

[0025] Optionally, the two toe bars are connected to the wheels on both sides respectively, and one of the two toe bars is connected to the subframe 10 through the mounting plate 210 and the mounting post 300. Alternatively, the two toe bar mounting structures 400 are set on both sides of a mounting post 300, so as to be connected to the two toe bars respectively. Or, two spaced mounting posts are set, and the two toe bars are connected to the two toe bars respectively through the two mounting posts.

[0026] This invention provides a subframe comprising a subframe body, a plurality of suspension structures protruding from the subframe body, a mounting post protruding from the subframe body and located on the same side of the subframe body as the suspension structures, and a toe-in mounting structure disposed on the mounting post. The suspension structures have a mounting plate at their top, and the toe-in can be clamped between the mounting post and the mounting plate. That is, in the toe-in mounted state, the suspension structure with the mounting plate and the mounting post can support each other, thereby improving the structural rigidity of the subframe. This increase in structural rigidity is not achieved by adding material, thus not increasing the weight of the subframe.

[0027] In some embodiments, Figure 1The material of the subframe 10 can be any material with sufficient structural strength. Exemplarily, the subframe 10 is integrally formed by aluminum alloy. With the special material properties of aluminum alloy and innovative and efficient structural design, this aluminum alloy subframe has very good NVH (noise vibration hashness, representing vibration damping and noise reduction performance), stiffness and durability performance.

[0028] In some embodiments, such as Figure 2 As shown, the overall frame structure of the subframe 10 adopts an "I"-shaped cross-section, enabling the rear subframe to obtain the maximum bending resistance with the least amount of material (the mounting points of each rod on the subframe mainly bear lateral impacts), achieving an effective balance between frame lightweight and strength performance.

[0029] In some embodiments, such as Figure 3 As shown, Figure 2 The subframe body 100 in it includes a front cross member 110, a rear cross member 120, a left longitudinal beam 130 and a right longitudinal beam 140. The extending directions of the front cross member 110 and the rear cross member 120 are parallel and spaced apart. In the direction perpendicular to the extending direction of the front cross member 110, the left longitudinal beam 130 and the right longitudinal beam 140 are spaced apart and fixed to the front cross member 110 and the rear cross member 120 at both ends respectively, forming a structure similar to a "square" shape. At the same time, since the rear subframe in the present invention needs to assemble a rear-mounted motor, 3 mounts are designed. The front mount structure is located on the front cross member, and the left, right and right rear mount structures are located on both sides of the rear cross member. At the same time, the drive motor is connected to the subframe 10 through the mount structure 200. In order to effectively manage the torque excitation of the motor during startup, the mount structure 200 includes a front mount structure 220 and two rear mount structures 230. The two rear mount structures 230 are spaced apart on the rear cross member 120, and the front mount structure 220 is arranged on the front cross member 110. And in the direction parallel to the extending direction of the front cross member 110, the front mount structure 220 is located between the two rear mount structures 230 to form a triangular fixed structure to reliably support the drive motor.

[0030] In some embodiments, such as Figure 3 As shown, the mount structure 200 includes two rear mount structures 230, and in the direction of the central axis of the rear mount structure 230, the two rear mount structures 230 are spaced apart. The top of the rear mount structure 230 has a mounting plate 210. Among them, there are two mounting columns 300, and the two mounting columns 300 are spaced apart and respectively close to the two rear mount structures 230. One front beam alignment rod mounting structure 400 is provided on each of the two mounting columns 300, so that the two front beam alignment rods can be connected to the subframe 10 through the mounting plates 210 of the two mounting columns 300 on both sides and the two rear mount structures 230 respectively.

[0031] Optionally, such as Figure 1 As shown, the subframe 10 also includes a subframe mounting structure 500, which is used to fix and connect to the frame or body. An elastic damping element is provided in the subframe mounting structure 500, and the elastic damping element can be a rubber bushing. The suspension structure 200 is close to the subframe mounting structure 500, and a reinforcing structure 510 is provided between the suspension structure 200 and the subframe mounting structure 500. The reinforcing structure 510 enables the suspension structure 200 and the subframe mounting structure 500 to support each other, further improving the overall rigidity of the subframe 10.

[0032] In some embodiments, such as Figure 1 As shown, the suspension structure 200 also has a support structure 240, which extends from the top of the suspension structure 200 and is fixedly connected to the outer surface of the mounting plate 210 on the side opposite to the mounting post 300. That is, the support structure 240 is used to support the mounting plate 210. The force exerted by the toe bar on the mounting plate 210 can be transmitted to the suspension structure 200 through the support structure 240 and then to the subframe body 100 through the suspension structure 200. Optionally, the support structure 240 and the mounting plate 210 form an "L" shaped structure, which effectively distributes the impact force of the toe bar to the entire suspension mounting structure and then to the subframe body 100 through the suspension structure.

[0033] In some embodiments, such as Figure 1 As shown, the subframe 10 also includes a spring arm mounting structure 600, which is disposed on the mounting column 300. By disposing of both the spring arm mounting structure 600 and the toe-in mounting structure 400 on the mounting column 300, the spring arm mounting structure 600 and the suspension structure 200 can also support each other, thereby further improving the overall structural rigidity of the subframe 10. At the same time, this arrangement makes the structure of the subframe 10 more compact and eliminates the need for additional columns to house the spring arm mounting structure 600, thus reducing the weight of the subframe 10. Moreover, the spring arm mounting structure 600 is located above the toe-in mounting structure 400 and the mounting plate 210, so that the spring arm mounting structure 600 will not interfere with the mounting plate 210 and the toe-in mounting structure 400 during assembly.

[0034] Among them, such as Figure 3 As shown, there are two spring arm mounting structures 600, which are respectively set on two mounting columns 300, so that they can be connected to two spring arms.

[0035] Optional, such as Figure 3As shown, the subframe 10 also includes a mounting beam 310. The two ends of the mounting beam 310 are fixedly connected to two spaced mounting columns 300, thereby supporting the two mounting columns 300 through the mounting beam 310, further improving the structural rigidity of the subframe 10. In addition, the mounting beam 310 also adds a force transmission structure between the left longitudinal beam 130 and the right longitudinal beam 140, which plays a very important role in strengthening the bending resistance of the left longitudinal beam 130 and the right longitudinal beam 140.

[0036] Optional, such as Figure 4 As shown, the cross section of the mounting beam 310 is U-shaped. Through the cross section design, the weight of the mounting beam 310 is reduced as much as possible while ensuring sufficient support for the spring arm mounting structure 600, thus achieving a balance between performance and weight.

[0037] Optional, such as Figure 5 As shown, on the back of the subframe body 100 Figure 1 The mounting column 300 and the suspension structure 200 have a back reinforcement structure 150 on one side. The back reinforcement structure 150 is located directly below the mounting column 300 and the suspension structure 200. The overall structural rigidity of the subframe 10 is further improved through local structural reinforcement.

[0038] In some embodiments, such as Figure 1 As shown, a stabilizer bar mounting structure 160 is provided on the outer surface of the subframe mounting structure 500. By arranging the stabilizer bar mounting structure 160 at the subframe mounting structure 510, this hard point arrangement not only provides very high installation stiffness performance for the stabilizer bar mounting point (after the subframe mounting point and the vehicle body are installed, it can provide very stable support for the stabilizer bar mounting point), but also reduces the leverage ratio of the stabilizer bar to a minimum, providing a very smooth handling feel for the vehicle and improving the vehicle's comfort.

[0039] In some embodiments, such as Figure 6 As shown, the subframe 10 also includes a roll bar mounting structure 700. The roll bar mounting structure 700 extends from the outer surface of the subframe body 100, and there is an arc transition surface 170 between the roll bar mounting structure 700 and the subframe body 100, making the original "L"-shaped mounting structure of the roll bar mounting structure 700 smoother at the corner position and reducing the risk of stress concentration; optionally, such as Figure 6As shown, the roll bar mounting structure 700 is disposed on the subframe longitudinal beam and located between the front suspension structure 220 and the rear suspension structure 230, and is located on the side closer to the rear suspension structure 230. The rear suspension structure 230 is located near the mounting column 300, thus placing the roll bar mounting structure 700 on the side closer to the mounting column 300. The mounting column 300 reliably supports the roll bar mounting structure 700. Furthermore, the mounting crossbeam 310 connecting the two mounting columns 300 provides a load transfer channel for the load borne by the roll bar mounting structure 700, allowing the load to be transferred to the other side of the subframe body 100. This structure forms four load transfer channels for the roll bar mounting structure 700 (the four transfer channels are as follows: ...). Figure 6 (As indicated by the middle arrow), thereby improving the structural stiffness of the roll bar mounting structure 700. Optionally, such as... Figure 6 As shown, the subframe body 100 is provided with a locally thickened structure 180, and the roll bar mounting structure 700 is fixed to the subframe body 100 through the locally thickened structure 180 to improve the local stiffness of the roll bar mounting structure 700. A locally reinforcing structure 190 is provided in the area of ​​the subframe body 100 directly opposite the roll bar mounting structure 700, thereby connecting the two side walls of the "I"-shaped structure of the cross-section of the subframe body 100, guiding the load of the roll bar mounting point to be transferred to the other side of the "I"-shaped structure, and further improving the structural strength of the subframe 10.

[0040] In some embodiments, such as Figure 7 As shown, the subframe 10 also includes an upper link connecting structure 810 and a lower link connecting structure 820. The upper link connecting structure 810 and the lower link connecting structure 820 are located at the front end of the subframe body 100, which can effectively optimize the anti-dive and anti-lift characteristics of the vehicle during acceleration or braking, and can also provide effective support for the mounting structure of the upper and lower links. In this way, it is not necessary to strengthen the mounting structure of the upper and lower links through a large number of structures.

[0041] Optional, such as Figure 7 As shown, the mounting structure of the upper and lower connecting rods consists of two mounting surfaces. A locally thickened area 180 is set at the position directly opposite the mounting surface of the upper connecting rod to improve the rigidity of the local structural wall. At the mounting point area, transverse and longitudinal reinforcing ribs are set on both the front and back sides of the subframe body 100. These two reinforcing ribs further connect the two side walls of the "I"-shaped structure of the subframe body 100 cross section, guiding the load of the upper connecting rod mounting point to the other side of the "I"-shaped structure, thereby improving the strength performance of the upper connecting rod mounting point.

[0042] Furthermore, by adopting an arc and outward expansion structural design in the installation area of ​​the subframe body 100, that is, the subframe installation structure protrudes from the subframe body 100 and is transitioned through an arc-shaped curved surface, so that the subframe body forms a stable triangular structure in the installation area, which helps to strengthen the rigidity of the subframe body at the corner position and avoid stress concentration problems.

[0043] Optional, such as Figure 8 As shown, the two mounting surfaces of the lower link are directly seated on the mounting stiffeners of the upper link. Although the mounting position of the lower link is still suspended above the subframe body frame, the design of the lower link mounting structure 820 with an inclined structure increases the fusion area between the lower link mounting surface and the subframe body 100, allowing the load at the lower link mounting point to be better distributed on the subframe body 100 structure, thereby improving the rigidity and strength performance of the lower link mounting structure 820.

[0044] This invention also provides a vehicle, which is an electric vehicle or a hybrid vehicle, and the vehicle has a drive motor. The structure of the vehicle will be described below with reference to various embodiments.

[0045] In some embodiments, the vehicle includes, as shown in the accompanying drawings, Figures 1 to 8 The subframe 10 shown in any of the images includes a drive motor and a toe bar. The drive motor is fixedly connected to the suspension structure and thus connected to the subframe 10. The toe bar is connected to the subframe 10 through the toe bar mounting structure 400 and is clamped between the mounting plate and the mounting column.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
