[0034] To solve the technical problem of insufficient structural stiffness of the existing vehicle powertrain mount 100, this technical solution proposes a mounting structure, including:

[0035] Two mounts 100, which are spaced apart; and

[0036] A connection component 200 that connects the two mounts 100 so that the two mounts 100 support each other through the connection component 200.

[0037] Compared with the prior art, in the technical solution of the present invention, the mounting structure includes mounts 100, and there are two mounts 100, which are spaced apart and used for mounting the motor 10; in addition, the mounting structure further includes a connection component 200, which connects the two mounts 100, and the two mounts 100 support each other through the connection component 200. Thus, when the motor 10 is operating, the two mounts 100 can support each other through the connection component 200, which is beneficial to reducing the deformation of the two mounts 100 caused by the vibration of the motor 10, beneficial to improving the dynamic stiffness of the mounting structure, and further meeting the usage requirements of the high-power and high-torque motor 10.

[0038] Specifically, as shown in the figure, in this embodiment, the suspension structure includes brackets 100. There are two brackets 100, both of which are plate-like structures. The two brackets 100 are arranged in parallel at intervals and are installed on the vehicle body by means of bolts or the like. The motor 10 of the vehicle is accommodated between the two brackets 100. Each bracket 100 is fixed to the motor 10 by bolts, so that the motor 10 can be installed on the vehicle body. In addition, in order to improve the dynamic stiffness of the bracket 100, the suspension structure further includes a connection component 200. The connection component 200 can be a support rod with a fixed length. The support rod is arranged between the two brackets 100, and the two ends of the support rod are respectively connected to the brackets 100 at both ends. The connection method can be riveting or screwing. In this way, the two brackets 100 are connected into one body by the connection component 200. When the motor 10 is working, the torsional force generated by the operation of the motor 10 can be transmitted between the two brackets 100. At this time, the two brackets 100 support each other, which is beneficial to reducing the deformation of the two brackets 100 generated during the operation of the motor 10, thereby being beneficial to improving the dynamic stiffness of the bracket 100, and further improving the support effect of the bracket 100 on the motor 10 and alleviating the high-frequency NVH problem of the motor 10.

[0039] Furthermore, the connection component 200 has a first end and a second end. The first end and the second end are respectively connected to a bracket 100, and the first end and the second end are movably connected so that the two brackets 100 can approach or move away from each other. Specifically, as shown in the figure, in order to adjust the dynamic stiffness of the suspension structure, in this embodiment, the connection component 200 is provided with opposite first and second ends. Among them, the first end is connected to a bracket 100, the second end is connected to another bracket 100, and the first end and the second end are movably connected and can approach or move away from each other. The connection component 200 can be a screw rod structure with different threads at both ends. The two ends of the screw rod are respectively threadedly connected to the two brackets 100. By rotating the screw rod, the two brackets 100 can be driven to approach or move away from each other. By adjusting the distance, the pre-tightening force between the two brackets 100 and the connection component 200 can be adjusted, and further the ability of the two brackets 100 to resist deformation, that is, the adjustment of the dynamic stiffness, can be realized, so as to adapt the suspension structure to different working conditions.

[0040] Furthermore, the connection component 200 includes:

[0041] Two first connection members 210 are spaced apart, and the ends of the two first connection members 210 facing away from each other form the first end or the second end; and

[0042] A first adjustment member 220 is drivingly connected to the two first connection members 210 to drive the two first connection members 210 to approach or move away from each other.

[0043] Specifically, as Figure 1, in this embodiment, the connection assembly 200 includes a first connecting member 210 and a first adjusting member 220. Among them, there are two first connecting members 210. The mutually facing ends of the two first connecting members 210 form the above-mentioned first end and second end. The first adjusting member 220 is arranged between the two first connecting members 210 and is drivingly connected to the two first connecting members 210. The connection assembly 200 may include a connecting rod. A sleeve is slidably connected to each of the opposite ends of the connecting rod. Each sleeve is correspondingly connected to a bracket 100. In addition, positioning holes corresponding to each other in position may be opened on the outer peripheral wall of the connecting rod and the outer peripheral wall of the sleeve. A positioning pin is inserted into the positioning hole to fix the position of the connecting rod and the sleeve. By opening a plurality of positioning holes along the axial direction of the connecting rod and switching the positioning pin in different positioning holes, the overall length of the connection assembly 200 can be adjusted, and further the distance between the two brackets 100 can be adjusted.

[0044] Furthermore, one end of the first adjusting member 220 is provided with a first thread, and the other end of the first adjusting member 220 is provided with a second thread. The first thread and the second thread have opposite helix directions. One of the two first connecting members 210 is screwed to the first thread, and the other of the two first connecting members 210 is screwed to the second thread. Specifically, as Figure 1-2 shown, in this embodiment, the first adjusting member 220 is a circular rod-shaped structure. A first thread is formed at one end of the first adjusting member 220, and a second thread is formed at the other end of the first adjusting member 220. Among them, the rotation directions of the first thread and the second thread are opposite. The first connecting member 210 is also a rod-shaped structural member. The two first connecting members 210 are respectively arranged at the opposite ends of the first adjusting member 220, and threaded holes are opened at the ends of the first connecting members 210 facing the first adjusting member 220. The two first connecting members 210 are respectively threadedly connected to the opposite ends of the first adjusting member 220. In addition, the mutually remote ends of the two first connecting members 210 are respectively fixedly connected to the two brackets 100. In this way, when the first adjusting member 220 is driven to rotate around its own axis, since the helix directions of the first thread and the second thread of the first adjusting member 220 are opposite, the two first connecting members 210 can be driven to approach or move away from each other. Through the structural design of this solution, the distance between the two brackets 100 can be conveniently adjusted, and thus the dynamic stiffness of the suspension structure can be conveniently adjusted.

[0045] Furthermore, the connection assembly 200 further includes fasteners 230. One fastener 230 is respectively provided corresponding to the first thread and the second thread. The two fasteners 230 are arranged between the two first connecting members 210 and are used to abut against the corresponding first connecting members 210.

[0046] In addition, to ensure the stability of the position of the first adjusting member 220 after adjustment, the connecting assembly 200 further includes a fastening member 230. In this embodiment, the fastening member 230 is a nut structure, and a fastening member 230 is connected to each of the first thread and the second thread. Moreover, the fastening member 230 on the first thread abuts against the end of the first connecting member 210 provided on the first thread. In this way, the first connecting member 210 and the fastening member 230 can abut against each other through the first thread, and the thread teeth of the first thread are clamped and fixed, preventing relative rotation between the first connecting member 210 and the first adjusting member 220 at the first thread and ensuring the stability of the state of the first adjusting member 220. Similarly, the fastening member 230 on the second thread abuts against the end of the first connecting member 210 on the second thread. In this way, the first connecting member 210 and the fastening member 230 can abut against each other through the second thread, and the thread teeth of the second thread are clamped and fixed, preventing relative rotation between the first connecting member 210 and the first adjusting member 220 at the second thread.

[0047] Further, an operation position 221 is provided on the outer peripheral wall of the first adjusting member 220. The operation position 221 is used to cooperate with a manual tool to drive the first adjusting member 220 to move through the manual tool.

[0048] Further, the operation position 221 is a convex structure protruding from the outer peripheral wall of the first adjusting member 220; or, the operation position 221 is a groove structure provided on the outer peripheral wall of the first adjusting member 220.

[0049] To facilitate the adjustment of the first adjusting member 220, an operation position 221 can be provided on the outer peripheral wall of the first adjusting member 220. The operation position 221 can be a protrusion provided on the outer peripheral wall of the first adjusting member 220, and the shape of the protrusion can be matched with the shape of an open-ended wrench. By engaging the open-ended wrench with the protrusion and turning the open-ended wrench, the first adjusting member 220 can be driven to rotate. In addition, the operation position 221 can also be a groove provided on the outer peripheral wall. The groove extends along the radial direction of the first adjusting member 220. By inserting an Allen wrench or any rod-shaped manual tool into the groove and turning it, the first adjusting member 220 can also be driven to rotate along its own axis, realizing the adjustment of the first adjusting member 220.

[0050] Further, one of the two brackets 100 is provided with a connection hole. The connecting assembly 200 includes:

[0051] A second connecting member 240, one end of which is connected to the other bracket 100, and the other end is movably inserted through the connection hole;

[0052] Two second adjusting members 250, both of the two second adjusting members 250 are threadedly connected to the second connecting member 240 and abut against opposite sides of the connection hole.

[0053] Specifically, as Figure 3-4 shown, the second implementation manner of the connection assembly 200 is given in this embodiment. In this embodiment, the connection assembly 200 includes a second connecting member 240, and the second connecting member 240 can also be a rod-shaped structural member. The second connecting member 240 has opposite third and fourth ends. Its third end is fixedly connected to one of the brackets 100, and the fourth end extends toward the other bracket 100. In addition, a connection hole is provided on the other bracket 100. The fourth end of the second connecting member 240 movably extends into the connection hole and is in clearance fit with the connection hole. In addition, the connection assembly 200 further includes two second adjusting members 250. The second adjusting member 250 can be a nut. Threads are provided at the fourth end of the second connecting member 240. The two second adjusting members 250 are respectively arranged on opposite sides of the connection hole and are threadedly connected to the threads on the second connecting member 240. The two second adjusting members 250 jointly clamp opposite sides of the connection hole. When it is necessary to drive the two brackets 100 to approach each other, the second adjusting member 250 located between the two brackets 100 can be adjusted to be away from the connection hole, and then the other second adjusting member 250 is operated to drive the bracket 100 provided with the connection hole to move closer to the other bracket 100 until it abuts against the other second adjusting member 250. When it is necessary to drive the two brackets 100 to move away from each other, the reverse operation process as described above can be adopted, that is, first adjust the second adjusting member 250 away from the third end away from the connection hole, and then adjust the other second adjusting member 250.
