Specific embodiments

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all of them. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0026] As used herein, the mention of "embodiment" means that the specific features, structures or characteristics described in connection with the embodiment may be included in at least one embodiment of the present application. The appearance of this phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0027] The following describes in detail the subframe and vehicle provided by the present utility model in conjunction with embodiments.

[0028] In this application, the descriptions of various directions refer to the orientation when the subframe is installed on the vehicle and working properly. The front-rear direction is the direction from the front of the vehicle to the rear; the left-right direction is the left-right direction of the vehicle, approximately horizontal; the up-down direction is the direction from the roof of the vehicle to the bottom, approximately perpendicular to the bottom surface.

[0029] Please refer to Figures 1 to 3 , Figure 1 , which is an exploded structural schematic diagram of an embodiment of the subframe of this application, and includes a subframe main body, a connecting member and a mounting tube; Figure 2 is Figure 1 a top view schematic diagram of the subframe main body and the connecting member in Figure 3 is Figure 2 an exploded structural schematic diagram of . This application provides a subframe. The subframe includes a subframe main body 1 and a connecting member 2. When the subframe is used on a vehicle, the subframe main body 1 is fixedly connected to other components of the vehicle through the connecting member 2, for example, fixedly connected to the vehicle body or the suspension system. This application takes the connection between the subframe and the vehicle body as an example for illustration.

[0030] The subframe main body 1 is provided with a connection hole 101. The connecting member 2 is installed in the connection hole 101. And the connecting member 2 can rotate around the center line of the connection hole 101 within the connection hole 101. That is, the connecting member 2 rotates relative to the subframe main body 1 around the center line of the connection hole 101. It can be understood that the number of connecting members 2 can be one or more.

[0031] Wherein, the connecting member 2 is provided with a mounting hole 201. The connecting member 2 is connected to the vehicle body through the mounting hole 201. When the connecting member 2 rotates around the center line of the connection hole 101, the vehicle body rotates synchronously with the connecting member 2 around the center line of the connection hole 101.

[0032] The center line of the mounting hole 201 does not coincide with the center line of the connecting hole 101. The center line of the mounting hole 201 of the connecting member 2 is set at a position deviating from the center line of the connecting hole 101. That is, an eccentric structure exists between the connecting member 2 and the subframe main body 1. When the connecting member 2 rotates around the center line of the connecting hole 101, the mounting hole 201 also rotates within the connecting hole 101. However, since the center lines of the mounting hole 201 and the connecting hole 101 do not coincide, when the mounting hole 201 rotates, the position of the mounting hole 201 on the subframe main body 1 changes. For example, please refer to Figure 2 , when the connecting member 2 rotates around the A direction, that is, when the connecting member 2 rotates counterclockwise around the center line of the connecting hole 101, it drives the mounting hole 201 to move leftward to the position of the mounting hole 201A, thereby driving the vehicle body fixed to the mounting hole 201 to move leftward relative to the subframe main body 1; when the connecting member 2 rotates around the B direction, that is, when the connecting member 2 rotates clockwise around the center line of the connecting hole 101, it drives the mounting hole 201 to move rightward to the position of the mounting hole 201B, thereby driving the vehicle body fixed to the mounting hole 201 to move rightward relative to the subframe main body 1.

[0033] Therefore, when the subframe is used in a vehicle, the mounting hole 201 of the connecting member 2 is fixedly connected to the vehicle body. When the four-wheel alignment of the vehicle is deviated, the connecting member 2 is adjusted so that the connecting member 2 rotates around the center line of the connecting hole 101 within the connecting hole 101. At this time, since the center lines of the connecting hole 101 and the mounting hole 201 do not coincide, forming an eccentric structure, when the connecting member 2 rotates, the position of its mounting hole 201 changes relative to the subframe main body 1, thereby driving the position of the vehicle body or the suspension system relative to the subframe main body 1 to change, so as to correct the deviation of the four-wheel alignment and meet the accuracy of the four-wheel alignment parameters. And in this application, by rotating the connecting member 2 within the connecting hole 101 to adjust the position of the subframe main body 1 relative to the vehicle body, there is no need to replace the subframe main body 1 again, reducing the process and saving the usage cost.

[0034] The distance between the center line of the mounting hole 201 and the center line of the connecting hole 101 affects the adjustment range, and this distance can be set according to the actual situation. The larger this distance is, the larger the adjustment range is, which is beneficial to precise adjustment. The smaller this distance is, the smaller the adjustment range is, which is beneficial to quick adjustment.

[0035] The mounting hole 201 of the connecting member 2 is fixedly connected to the vehicle body, and this fixed connection method includes but is not limited to welding, screwing, clamping, bonding, etc. In a specific embodiment, bolts are used to fixedly connect the vehicle body within the mounting hole 201.

[0036] Please refer to Figure 1 and Figure 4 , Figure 4 is Figure 1Schematic diagram of the assembly structure. In one embodiment, the subframe main body 1 is in a frame structure, enabling the subframe to have sufficient load-bearing capacity and anti-deformation ability. The connection holes 101 are arranged along the diagonal of the subframe main body 1. The connection holes 101 are respectively arranged at both ends of the diagonal of the subframe main body 1.

[0037] In the above manner, when the connecting member 2 in the connection hole 101 rotates, since the connection holes 101 are diagonally arranged, the mounting holes 201 are also diagonally arranged on the subframe main body 1. Therefore, when performing four-wheel alignment adjustment, two adjacent sides of the vehicle body fixedly connected to the mounting holes 201 can be adjusted synchronously, and the force generated by the rotation of the connecting member 2 can be evenly distributed on the vehicle body. At the same time, the connection holes 101 are arranged along the diagonal of the subframe main body 1, which can reduce the stress concentration phenomenon and improve the reliability of the subframe main body 1.

[0038] The above frame structure can be roughly a rectangular frame, a triangular frame, etc., which are not limited herein. In a specific embodiment, the subframe main body 1 is roughly a square frame, such as a rectangular frame. Specifically, the subframe main body 1 includes two parallel cross beams 131, 132 and two parallel longitudinal beams 141, 142, and the cross beams 131, 132 are connected to the longitudinal beams 141, 142 to form a rectangular frame structure. The subframe main body 1 is also provided with two second fixing holes 103, and the second fixing holes 103 are arranged at the positions where the cross beam 131 and the longitudinal beam 142 are connected and at the positions where the cross beam 132 and the longitudinal beam 141 are connected. And the two second fixing holes 103 are arranged on a pair of diagonals of the subframe main body 1. Thus, the diagonal formed by the connection line of the positions of the mounting holes 201 intersects with the diagonal formed by the connection line of the positions of the two second fixing holes 103. Such a setting can, while maintaining the stability of the overall structure of the subframe main body 1, enable the mounting arm 12 to disperse and buffer the external impact force received by the subframe, reducing the possibility of deformation of the subframe due to impact.

[0039] More specifically, please refer to Figure 4 and Figure 5 , Figure 5 is Figure 1 Schematic diagram of the structure of the mounting tube in Figure 5As shown, the mounting pipe 3 is provided with a second fixing hole 103. The second fixing hole 103 runs through the mounting pipe 3. Bolts are used to pass through the vehicle body and the second fixing hole 103 to fixedly connect the vehicle body within the second fixing hole 103. The setting of the mounting pipe 3 can effectively enhance the stability of the overall structure of the subframe main body 1, enabling the mounting pipe 3 to better bear and disperse the stress generated by the subframe main body 1, reducing the possibility of deformation and damage of the subframe main body 1.

[0040] The mounting pipe 3 is also arranged along the diagonal of the subframe main body 1. Specifically, as Figure 4 shown, the connecting holes 101 are respectively arranged at the positions where the cross beam 131 and the longitudinal beam 141 are connected and at the positions where the cross beam 132 and the longitudinal beam 142 are connected; the mounting pipe 3 is arranged at the positions where the cross beam 131 and the longitudinal beam 142 are connected and at the positions where the cross beam 132 and the longitudinal beam 141 are connected. Thus, the diagonal formed by the position connection line of the two mounting pipes 3 intersects with the diagonal formed by the position connection line of the two connecting holes 101. Such a setting can, while maintaining the stability of the overall structure of the subframe main body 1, cause the position of the mounting hole 201 to change relative to the subframe main body 1 when the connecting member 2 rotates, thereby driving the change in the position of the vehicle body or the suspension system relative to the subframe main body 1, so as to correct the deviation in four-wheel alignment and meet the accuracy of four-wheel alignment parameters.

[0041] Please refer to Figure 6 , Figure 6 which Figure 1 is a schematic structural view of the connecting member in

[0042] The connection manner between the operating part 22 and the shaft body part 21 can be set according to the actual situation and is not limited herein. In a specific embodiment, the operating part 22 is fixed to the first end of the shaft body part 21, and the fixed connection manner includes but is not limited to welding, screwing, clamping, bonding, etc. In another specific embodiment, the operating part 22 and the shaft body part 21 are integrally formed and protrude from the first end of the shaft body part 21. The structural shapes of the operating part 22 and the shaft body part 21 can be "T" shaped, and an installation hole 201 penetrating through the shaft body part 21 and the operating part 22 is provided in the middle.

[0043] When the operating part 22 is fixed to the first end of the shaft body part 21, the types of the operating part 22 include but are not limited to a snap cap, a nut, a hexagon head flange, etc.

[0044] When it is necessary to rotate the connecting piece 2, an adjusting tool (such as a wrench) is fixed on the operating part 22. When the adjusting tool is rotated, the operating part 22 is driven to rotate, so that the connecting piece 2 rotates around the center line of the connecting hole 101, and further the position of the subframe relative to the vehicle body is adjusted.

[0045] Please continue to refer to Figure 3 、 Figure 7 and Figure 8 , Figure 7 is Figure 2 the schematic assembly structure diagram of Figure 8 is Figure 2 the schematic cross-sectional diagram of . In an embodiment, the subframe main body 1 further includes a protective sleeve 11. A part of the shaft body part 21 of the connecting piece 2 is located inside the protective sleeve 11. The subframe main body 1 is provided with a first fixing hole 102. The protective sleeve 11 is fixed in the first fixing hole 102. The connecting hole 101 is a central pipe hole arranged along the axis of the protective sleeve 11. That is, the connecting hole 101 is the inner hole of the protective sleeve 11.

[0046] Providing the protective sleeve 11 can separate the shaft body part 21 of the connecting piece 2 from the external environment, reduce the possibility that the connecting piece 2 is interfered and damaged by external objects, and extend the service life of the connecting piece 2.

[0047] The connection manner between the connecting piece 2 and the protective sleeve 11 can be set according to the actual situation and is not limited herein. In a specific embodiment, the outer peripheral wall of the shaft body part 21 of the connecting piece 2 and the inner peripheral wall of the protective sleeve 11 are both smooth surfaces. The connecting piece 2 is in direct contact with the protective sleeve 11. In another specific embodiment, the connecting piece 2 is provided with an external thread, and the protective sleeve 11 is provided with an internal thread. The connecting piece 2 is threadedly connected with the protective sleeve 11.

[0048] The connection manner between the protective sleeve 11 and the subframe main body 1 can be set according to actual situations and is not limited herein. In a specific embodiment, the protective sleeve 11 and the subframe main body 1 are integrally formed. In another specific embodiment, the protective sleeve 11 and the subframe main body 1 are fixedly connected, and the fixed connection manner includes but is not limited to welding, screwing, clamping, bonding, etc.

[0049] In one embodiment, as Figure 1 and 4 shown, the subframe main body 1 includes mounting arms 12, and the first fixing holes 102 are arranged on the mounting arms 12. The mounting arms 12 are arranged on the diagonal of the subframe main body 1. Specifically, the mounting arms 12 are respectively arranged at the positions of the joints of the cross beam 131 and the longitudinal beam 141 and at the positions of the joints of the cross beam 132 and the longitudinal beam 142. And each mounting arm 12 is protruded from the extending ends of the cross beams 131, 132 or the longitudinal beams 141, 142. The mounting arm 12 and the subframe main body 1 can be an integrally formed structure. The mounting arm 12 can also be connected to the cross beams 131, 132 or the longitudinal beams 141, 142 of the subframe main body 1 through an adjustable structure (such as a rotating shaft, a hinge, etc.), allowing the length and angle of the mounting arm 12 to be adjusted within a certain range.

[0050] As Figure 3 shown, the mounting arm 12 is in a hollow tubular structure, which can significantly reduce the overall weight of the mounting arm 12 compared with a solid tube structure, and at the same time disperse and buffer external impact forces, reducing the possibility of the mounting arm 12 being deformed by impact, thereby enhancing the stability of the subframe. In a specific embodiment, the mounting arm 12 is in a square hollow tube structure, which includes a first mounting wall 121 and a second mounting wall 122 arranged oppositely. The first fixing hole 102 penetrates through the first mounting wall 121 and the second mounting wall 122.

[0051] During assembly, the shaft body part 21 sequentially passes through the first mounting wall 121 and the second mounting wall 122, the operating part 22 contacts the first mounting wall 121, and the anti - detachment part 23 contacts the second mounting wall 122, so that the connecting piece 2 is fixed to the subframe main body 1.

[0052] On the other hand, the present application provides a vehicle. The vehicle includes the subframe, the vehicle body and the fixing piece in any of the above - mentioned embodiments. The fixing piece fixedly connects the vehicle body in the mounting hole 201. That is, the fixing piece penetrates through the vehicle body and the mounting hole 201 to connect the vehicle body and the subframe. The types of the fixing piece include but are not limited to bolts, screws, etc.
