[0029] First, see Figures 1 to 4The embodiment of the present application provides a mounting structure 1, which includes a mounting body 11 and a first connecting member 12. The mounting body 11 includes a first mounting plate 111 and a support 112 disposed on the first mounting plate 111, the support 112 and the first mounting plate 111 are surrounded to form a cavity 113, a first interface is disposed on the support 112, the cavity 113 is configured to accommodate at least part of the first external device 2 and the first interface is configured to be rotatably connected to the first external device 2; the first connecting member 12 is connected to the mounting body 11 and protrudes out of the cavity 113, and the first connecting member 12 is configured to be connected to the second external device 3.

[0030] In some embodiments, the first mounting plate 111 and the support 112 may be an integrated structure. Optionally, the mounting body 11 and the support 112 may be integrally formed by stamping, bending, etc. The first connector 12 and the support 112 may be an integrated structure.

[0031] The cavity 113 enclosed between the support 112 and the first mounting plate 111 may be a circular cavity, a polygonal cavity, a U-shaped cavity, etc., and the number of openings formed on the support 112 and communicating with the cavity 113 may be one or more than two.

[0032] The first interface includes but is not limited to connecting structures such as connecting holes 11211 and connecting shafts.

[0033] An embodiment of the present application provides an installation structure 1, which includes an installation body 11 and a first connecting member 12. The installation body 11 of the installation structure 1 includes a first installation plate 111 and a support 112. The support 112 and the first installation plate 111 are surrounded by a cavity 113 to form a three-dimensional structure with high strength. The cavity 113 is used to accommodate a first external device 2, the first interface is used to connect the first external device 2, and the first connecting member 12 is used to connect the second external device 3. Therefore, the installation structure 1 can realize the installation and fixation of the first external device 2 and the first external device 2, and has fewer parts, low mold investment, and low production cost.

[0034] The first external device 2 may be a trailing arm, and the second external device 3 may be a crossbeam. The connection between the first connecting member 12 and the second external device 3 may be welding.

[0035] In some embodiments, the width of the first mounting plate 111 may be optionally smaller than the width of the second external device 3. Such a configuration enables the first mounting plate 111 to be connected to the second external device 3 by welding on both sides in the width direction, thereby increasing the connection points between the mounting structure 1 and the second external device 3, and further increasing the connection strength between the mounting structure 1 and the second external device 3.

[0036] The width of the support 112 only needs to match that of the second external device 3, and no specific width is required.

[0037] It should be noted that the mounting structure 1 provided in the embodiment of the present application can be used not only in the automotive field to realize the connection between the trailing arm and the crossbeam, but also in other technical fields.

Optionally, the cross-sectional shape of the first connector 12 may be a trapezoid.

[0043] In some embodiments, the first direction X may also be the length direction of the mounting body 11 , that is, the mounting body 11 is connected to the first connecting members 12 on both sides of the length direction thereof.

[0044] The mounting structure 1 provided in one embodiment of the present application realizes multi-point connection between the mounting structure 1 and the second external device 3 by providing a plurality of first connecting members 12, thereby increasing the connection strength between the mounting structure 1 and the second external device 3. Furthermore, by connecting the mounting body 11 with the first connecting members 12 on both sides of the first direction X, the mounting body 11 and the first connecting members 12 connected on both sides can enclose a receiving space, and the second external device 3 is placed in the receiving space for connection, which is beneficial to the positioning and installation of the mounting structure 1 and reduces the difficulty of assembly.
