DETAILED DESCRIPTION

[0030] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0031] The embodiments described in some embodiments of the present disclosure below do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0032] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0033] like Figures 1 to 7 As shown, an exemplary embodiment of the present disclosure provides a subframe, specifically, the subframe includes an upper plate body 1, a lower plate body 2, a reinforcing plate 3 and a first support sleeve 4. The upper plate body 1 and the lower plate body 2 form a receiving cavity, and a stabilizer bar mounting point is provided on the upper plate body 1. The reinforcing plate 3 is provided in the receiving cavity, and the reinforcing plate 3 is connected to the lower plate body 2. The first support sleeve 4 is provided in the receiving cavity, and the position of the first support sleeve 4 corresponds to the stabilizer bar mounting point, and the first support sleeve 4 is provided with an avoidance structure 41 for avoiding the interference part on the reinforcing plate 3.

[0034] The upper plate 1 is provided with a stabilizer bar mounting point, which is also called a stabilizer bar mounting interface, i.e., a position on the upper plate 1 for connecting with the stabilizer bar 8. Figure 6 As shown, the stabilizer bar 8 can be fixedly connected to the upper plate body 1 through the stabilizer bar mounting bracket 10. Figure 7 As shown, the stabilizer bar mounting bracket 10 can be constructed in an Ω shape, wherein the middle arched portion is used to press the stabilizer bar 8 onto the upper plate body 1 , and the plate-shaped portions on both sides are used to be connected to the upper plate body 1 via fastening bolts 9 .

[0035] The upper plate body 1 and the lower plate body 2 are constructed as split types and form a accommodating cavity inside, which is beneficial to the lightweight design of the entire vehicle on the one hand, and also convenient for installing the reinforcing plate 3 and the first supporting sleeve 4 on the other hand. That is, after installing the reinforcing plate 3, the first supporting sleeve 4 and other components, the upper plate body 1 and the lower plate body 2 are welded together.

[0036] Considering the adverse effect that the accommodation cavity formed inside the upper plate body 1 and the lower plate body 2 may have on the structural rigidity of the sub-frame, the reinforcement plate 3 is provided to improve the structural rigidity of the sub-frame without excessively increasing the weight of the sub-frame. For example, the lower plate body 2 is usually provided with components such as swing arms, so the reinforcement plate 3 is provided on the lower plate body 2 to improve the connection strength between the lower plate body 2 and these components.

[0037] The position of the first support sleeve 4 corresponds to the mounting point of the stabilizer bar, so that it can provide support for the mounting point of the stabilizer bar, thereby improving the durability and structural rigidity of the mounting point of the stabilizer bar. Considering that the space available for welding the first support sleeve 4 on the lower plate 2 is limited due to the presence of the reinforcement plate 3, the first support sleeve 4 interferes with the reinforcement plate 3. At this time, whether the reinforcement plate 3 is cancelled or the first support sleeve 4 is changed to a projection welding nut on the upper plate 1, it will have an adverse effect on the structural rigidity of the subframe. The present disclosure provides an avoidance structure 41 for avoiding the interference part on the reinforcement plate 3 on the first support sleeve 4, so that while retaining the reinforcement plate 3, there is still space for setting the first support sleeve 4.

[0038] It is worth noting that the interference portion on the reinforcing plate 3 here can be, for example, the edge of the reinforcing plate 3, or can also be a protrusion set on the reinforcing plate 3 to be introduced later. The avoidance structure 41 can be a avoidance opening formed on the peripheral wall of the first supporting sleeve 4 to be introduced later, or can also be a depression formed on the peripheral wall of the first supporting sleeve 4 by a process such as stamping.

[0039] The technical solution provided by the embodiment of the present disclosure may include the following beneficial effects: the sub-frame provided by the present disclosure is provided with a reinforcing plate 3 and a first supporting sleeve 4 in the inner cavity formed between the upper plate body 1 and the lower plate body 2, and the first supporting sleeve 4 is provided with an avoidance structure 41 for avoiding the interference part on the reinforcing plate 3. In this way, on the one hand, the reinforcing plate 3 can be fully utilized to improve the structural rigidity of the sub-frame, and on the other hand, the avoidance structure 41 enables the first supporting sleeve 4 to avoid interference with the reinforcing plate 3, so that within the limited layout space, the first supporting sleeve 4 can be used to improve the structural rigidity of the stabilizer bar installation point.

[0040] The avoidance structure 41 may be an avoidance opening formed on the peripheral wall of the first support sleeve 4, for example Figure 2 The first support sleeve 4 is configured with a crescent-shaped cross section. The crescent-shaped first support sleeve 4 can be, for example, a coiled tube with an opening, that is, a plate is bent into a tube with an opening, or a seamless tube can be directly cut to avoid the opening. The coiled tube with an opening usually has a higher yield strength than the seamless steel tube.

[0041] In some embodiments, Figure 2As shown, the interference part is a convex hump 31 which is arranged on the reinforcing plate 3 and bulges toward the upper plate body 1. One end of the first supporting sleeve 4 is arranged on the reinforcing plate 3, and the other end is in contact with the upper plate body 1. The avoidance structure 41 is used to avoid the convex hump 31. The convex hump 31 is raised when viewed from the direction of the upper plate body 1, and when viewed from the direction of the lower plate body 1, the interference part can also be said to be a bowl-shaped depression. Depending on the position on the subframe, the interference part is used to avoid different components installed on the subframe, such as the front lower arm. Different from the method of directly setting it on the lower plate body 1, the present invention sets the first support sleeve 4 on the reinforcing plate 3. On the one hand, there is no need to reserve welding space for the first support sleeve 4 on the lower plate body 2. On the other hand, compared with the method in which the two ends of the first support sleeve 4 respectively abut the upper plate body 1 and the lower plate body 2, the first support sleeve 4 set on the reinforcing plate 3 can be considered as a suspended setting. Since the reinforcing plate 3 provides support for the first support sleeve 4, the supporting ability of the first support sleeve 4 to the stabilizer bar mounting point will not be weakened, and it is also beneficial to save the length of the material of the first support sleeve 4, which is beneficial to lightweight design.

[0042] When assembling the stabilizer bar 8, the fastening bolts 9 are passed through the stabilizer bar mounting bracket 10, the upper plate body 1, the support sleeve and the lower plate body 2 from top to bottom. Among them, the reinforcing plate 3 is fixedly connected to the lower plate body 2 by welding, and the portion of the fastening bolts 9 exposed on the upper surface of the stabilizer bar mounting bracket 10 is fastened by the fastening nut, and the portion of the fastening bolts 9 exposed on the lower surface of the reinforcing plate 3 is fastened by the movable nut assembly, so that the upper plate body 1, the support sleeve 4, the reinforcing plate 3 and the lower plate body 2 can be connected into one by the fastening bolts 9, which is conducive to improving the durability and structural rigidity of the stabilizer bar installation point.

[0043] Considering the assembly error caused by the welding deformation of the structural parts, the position of the pre-welded nut may be misaligned, resulting in the inability to complete the assembly of the fastening bolt 9. Figure 3 and Figure 7 The subframe also includes a first movable nut assembly 5 arranged on the side of the reinforcing plate 3 away from the first support sleeve 4. The first fastening bolt 91 passes through the stabilizer bar mounting bracket 10, the upper plate body 1, the first support sleeve and the lower plate body 2 from top to bottom. The first movable nut assembly 5 includes a first nut seat 51 and a first nut 52 accommodated in the first nut seat 51. The first nut seat 51 is provided with a limiting rib 510. The limiting rib 510 is used to accommodate the first nut 52 in the first nut seat 51 so that it can be movable in the horizontal direction, for example, within a range of 1.2 mm. That is, the position of the nut is not completely fixed, so that even if there is a certain degree of misalignment due to welding deformation, the first fastening bolt 91 can still guide and correct itself to ensure that the first fastening bolt 91 and the first nut 51 cooperate smoothly.

[0044] Furthermore, refer to Figure 3 and Figure 4 The limiting rib 510 may include two first ribs 511 located on both sides of the first nut seat 51 in the first direction, and a second rib 512 located on one side in the second direction. The other side of the first nut seat 51 in the second direction is arranged toward the interference portion, so that the interference portion can limit the first nut 52 from the other side of the first nut seat 51 in the second direction. For example, the first nut seat 51 can be constructed as a rectangle and have three ribs, while the remaining side cannot be set with a rib point due to interference with the protrusion 31. Therefore, the protrusion 31 can be used as a compensation limit. Figure 3 As shown, a skirt structure is provided on the outer peripheral edge of the protrusion 31 , and the skirt structure and the other three ribs formed on the first nut seat 51 together limit the first nut 52 in the first nut seat 51 .

[0045] In addition, the limiting rib 510 may further include a side hook 513 disposed on the other side of the second direction of the first movable nut 5, and the side hook 513 is bent from the end of the first rib 511 to a direction parallel to the second rib 512. On the one hand, the side hook 513 has the functions of limiting and preventing rotation, and on the other hand, the side hook 513 is longer than the first rib 511 and the second rib 512, so that it is more conducive to being set in a limited space.

[0046] In some embodiments, Figure 2 As shown, the subframe may further include a second support sleeve 6, and the first support sleeve 4 and the second support sleeve 6 are respectively arranged on both sides of the stabilizer bar 8 in the axial direction. The first support sleeve 4 and / or the second support sleeve 6 are rolled tubes with openings, that is, the rolled tubes with openings are formed by bending the plate into a tubular shape with openings, and the rolled tubes with openings generally have better yield strength than seamless steel tubes.

[0047] Specifically, Figure 6 As shown, the stabilizer bar 8 is fixed to the upper plate body 1 through the stabilizer bar mounting bracket 10. Figure 7 As shown, the stabilizer bar mounting bracket 10 is constructed in an Ω shape, the arched portion in the middle is used to press the stabilizer bar 8 onto the upper plate body 1, and the plate-like portions on both sides are used to connect to the upper plate body 1 via fastening bolts 9. The positions of the first support sleeve 4 and the second support sleeve 6 correspond to the positions of the two fastening bolts 9, respectively. Among them, similar to the first support sleeve 4, the second support sleeve 6 can also be configured to be connected to the reinforcing plate 3 at one end and to the upper plate body 1 at the other end. And depending on whether the setting position of the second support sleeve 6 interferes with the reinforcing plate 3 or not, an avoidance structure can be provided or not, wherein in Figure 2 In the illustrated embodiment, no avoidance structure is provided around the second supporting sleeve 6 because there is no interference portion.

[0048] Furthermore, if Figure 3 and Figure 5 As shown, the subframe of the present disclosure also includes a second movable nut assembly 7 disposed on the side of the reinforcing plate 3 away from the second support sleeve 6, and the second movable nut assembly 7 includes a second nut seat 71 and a second nut 72 accommodated in the second nut seat 71, which is used to accommodate the second nut 72 in the second nut seat 71 in a horizontally movable manner. Similar to the first movable nut assembly 5, the second movable nut assembly 7 can also guide and correct the second fastening bolt 92 to ensure smooth cooperation between the second fastening bolt 92 and the second nut 72 when the structural member has a certain degree of misalignment due to welding deformation. And according to the second movable nut assembly 7, for example, when there is no interference part around, the second nut seat 71 includes two third ribs 711 located on both sides of the first direction, and two fourth ribs 712 located on both sides of the second direction. In addition, when there is interference around the second movable nut assembly 7, one of the ribs can be selectively omitted, or the rib can be replaced with the aforementioned side hook.
