Based on the above overall description, an exemplary structure of the suspension mounting structure of the present embodiment is as shown in fig. 1 and 2, and mounting the suspension 3 on the vehicle body 1 generally means mounting the suspension 3 on the subframe. The suspension mounting structure of the present embodiment is generally used for mounting of a rear suspension in a three-point pendulum suspension system, but it may be used for mounting of other suspensions 3. To facilitate understanding of the suspension mounting structure of the present embodiment, the structure of the suspension 3 will be described with reference to fig. 3 to 5, the aforementioned connecting assembly is provided at one end of the suspension 3 to be connected to the vehicle body 1, and the other end of the suspension 3 is provided with a connecting portion to be connected to a member to be mounted, which is generally a power unit.

The inner core 302 inserted into the first through hole is tubular, and the connecting portion is specifically a connecting hole 3021 formed by the inner core 302 itself. The suspension mounting structure of the present embodiment specifically refers to the connection between the end of the suspension 3 having the second through hole and the vehicle body 1, and the inner core 302 of the second through hole is provided with a positioning hole 3022 for inserting and matching with the positioning post 703 described below.

As a preferred embodiment, the coupling assembly of the present embodiment includes a bolt pair inserted into the suspension 3, and the engagement portion includes a mounting hole 201 provided in the vehicle body 1. The bolts 5 in the bolt pairs are disposed through the mounting holes 201, and the mounting holes 201 are elongated holes extending in the height direction of the vehicle body 1. Therefore, the position of a connecting point between the suspension 3 and the vehicle body 1 can be adjusted along the length direction of the mounting hole 201, so that the two ends of the suspension 3 can be adjusted to be in a horizontal state without being influenced by the manufacturing tolerance of the vehicle and the rigidity of the left and right suspensions 3, and the suspension 3 can have vibration isolation performance meeting the design requirement.

In this embodiment, in order to obtain better use effect, as shown in fig. 1 and fig. 2, two oppositely arranged mounting brackets are provided on the vehicle body 1, and one mounting hole 201 is provided on each of the two mounting brackets. The bolts 5 in the bolt pairs are arranged across the two mounting brackets and the two mounting holes 201 are both elongated holes. For the convenience of the following description, the two mounting brackets are referred to as a "first mounting bracket 2" and a "second mounting bracket 4", respectively, and the head of the bolt 5 is located outside the first mounting bracket 2, and the nut 7 is located outside the second mounting bracket 4.

As a specific embodiment, the first mounting bracket 2 has a structure as shown in fig. 8, one end is connected to the vehicle body 1, the other end is provided with a mounting hole 201, and the mounting hole 201 is a straight oblong hole. Of course, instead of providing the mounting hole 201 as a straight oblong hole, it is also possible to provide it as an arc-shaped oblong hole as shown in fig. 9. In addition, in order to provide the first mounting bracket 2 with a good structural strength, a flange 202 is formed along an edge of the first mounting bracket 2.

The second mounting bracket 4 has a structure as shown in fig. 10, and in addition to having the same structure as the first mounting bracket 2, a relief hole 401 is provided in the second mounting bracket 4 to be relieved from a positioning post 703 described below, and the relief hole 401 of the present embodiment communicates with the mounting hole 201 described above.

Furthermore, to further facilitate viewing the position of the float 603, a graduation mark indicating the position of the float 603 may be further provided between the two indication blocks 602. It should be noted that, in addition to the above-described structure, the level 6 may be directly formed by an existing structure.
