[0001] The present invention relates to the technical field of vehicle accessories, and particularly relates to a mounting structure of a mount and a vehicle. Background Art
[0002] With the development of automotive development technology, users' requirements for automotive performance are becoming increasingly strict. However, existing automobiles have the defect of generating vibrations when running on rough roads. As a link connecting excitation sources such as engines and chassis suspensions to the vehicle body system, the dynamic stiffness of the mounting structure of the mount is the key to affecting the shock absorption of the vehicle body.
[0003] In the mounting structure of the mount provided in the prior art, generally, a front section reinforcement of the side sill beam and a mount reinforcement are added inside the front section of the side sill beam of the mounting structure of the mount, and the mount reinforcement is overlapped with the front section reinforcement of the side sill beam and the outer panel of the side sill beam to form a closed cavity, which improves the dynamic stiffness of the mounting structure of the mount to a certain extent and reduces the vibration of the vehicle body. However, the technical solutions adopted in the prior art have limited improvement in the dynamic stiffness of the mounting structure of the mount, and consume more materials in the overlapping structure. Summary of the Invention

[0005] In order to achieve the above purposes, the technical solutions adopted by the present invention are as follows:

[0007] The side sill beam side plate and the front section of the side sill beam are arranged along the first direction and are connected to form a cavity extending along the second direction, and the front section reinforcement of the side sill beam is arranged on the inner side of the front section of the side sill beam;
[0008] The two support members are accommodated in the cavity and are spaced apart along the second direction, and each support member is respectively connected to the front section reinforcement of the side sill beam and the side sill beam side plate; the two threaded tubes are accommodated in the cavity and are arranged corresponding to the two support members respectively, and both ends of the threaded tube are respectively connected to the front section reinforcement of the side sill beam and the support member;
[0009] The side plate of the tank side beam, the front section reinforcement of the tank side beam and the front section of the tank side beam together with a correspondingly arranged threaded tube and a supporting member form a first closed section extending along the third direction;
[0010] The front section reinforcement of the cabin side beam and the front section of the cabin side beam together with the two threaded tubes and the two support members form a second closed cross-section extending along the second direction.
[0011] According to the above technical means, since the suspension mounting structure forms a first closed cross-section extending along the third direction at the support member, and forms a second closed cross-section extending along the second direction between the two support members, the polar moment of inertia of the suspension mounting structure can be increased to a greater extent, thereby improving the dynamic stiffness of the vehicle body attachment point of the suspension mounting structure, making the shock absorption effect of the automobile body more significant.
[0012] Furthermore, the support member has a groove body opened toward the front section reinforcement member of the cabin side beam, and the groove body is arranged through along the third direction;
[0013] The front section reinforcement of the cabin side beam covers at least a portion of the trough body;
[0014] Along the third direction, the threaded pipe at least partially extends into the trough body and is connected to the support member, and the surface of the support member at least partially facing away from the trough body is connected to the side plate of the cabin side beam.
[0015] According to the above technical means, since a groove body penetrating along the third direction is provided on the support member, it is convenient to connect the support member with the threaded pipe on the one hand, and it can also save materials for the support member and help control costs on the other hand.
[0016] Further, the two support members include a rear support member, and the rear support member includes a first U-shaped shell and two first overlapping portions respectively arranged on both side edges of the first U-shaped shell;
[0017] The first U-shaped shell is connected to the threaded tube and the side plate of the tank side beam respectively, and the opening faces the front section reinforcement of the tank side beam. The side plate of the tank side beam, the front section reinforcement of the tank side beam and the front section of the tank side beam together with the threaded tube and the first U-shaped shell form the first closed section;
[0018] The two first overlap portions are respectively connected to the front section reinforcement of the cabin side beam.
[0019] According to the above technical means, since the rear support is provided with a first U-shaped shell and a first overlapping portion, the rear support can be overlapped with the threaded tube, the front section reinforcement of the cabin side beam and the side plate of the cabin side beam respectively in different directions.
[0020] Further, the two support members further include a front support member, which includes a second U-shaped housing and two second overlapping portions respectively provided at the two side edges of the second U-shaped housing;
[0021] The second U-shaped housing is respectively connected to the threaded pipe and the side plate of the side beam of the cabin, and the opening faces the front section reinforcement of the side beam of the cabin. The side plate of the side beam of the cabin, the front section reinforcement of the side beam of the cabin, and the front section of the side beam of the cabin and the threaded pipe and the second U-shaped housing together form the first closed cross-section;
[0022] The two second overlapping portions are connected to the front section reinforcement of the side beam of the cabin.
[0023] According to the above technical means, since the second U-shaped housing and the second overlapping portions are provided on the front support member, the front support member can overlap with the threaded pipe, the front section reinforcement of the side beam of the cabin, and the side plate of the side beam of the cabin respectively in different directions.
[0024] Further, the first U-shaped housing includes a first U-shaped portion, a second U-shaped portion, and a first arc portion connected between the first U-shaped portion and the second U-shaped portion;

[0028] According to the above technical means, by limiting the dimensions of the first U-shaped portion and the second U-shaped portion in the first direction, the dimension of the first U-shaped portion can be optimized under the premise of ensuring the stable connection between the first U-shaped housing and the threaded pipe and the side plate of the side beam of the cabin, which is beneficial to cost control.
[0029] Further, the maximum dimension of the first U-shaped housing in the first direction is a third dimension, the maximum dimension of the second U-shaped housing in the first direction is a fourth dimension, and the third dimension is greater than the fourth dimension.
[0030] According to the above technical means, by limiting the maximum dimensions of the first U-shaped housing and the second U-shaped housing in the first direction, on the premise of ensuring that both the first U-shaped housing and the second U-shaped housing can be stably connected to the threaded pipe and the side plate of the cabin side beam, the dimensional optimization design of the first U-shaped housing and the second U-shaped housing is beneficial to cost control.
