[0040] Please refer to Figures 1 to 3, this application provides an integrated electric vehicle mounting structure 100, which is used to provide support for the vehicle weight, while mounting the electric drive assembly, and absorb and disperse the vibrations and impacts from the road surface through the suspension system to ensure the stability and comfort of the vehicle on uneven roads.

[0041] Specifically, the integrated electric vehicle mounting structure includes a vehicle frame 110 and a plurality of mounting components 120. The vehicle frame 110 includes two longitudinals 112 arranged oppositely and a front cross beam 114 and a rear cross beam 116 connected between the two longitudinals 112. The plurality of mounting components 120 are respectively arranged on the longitudinals 112 and the rear cross beam 116, and the plurality of mounting components 120 are used to fix the electric drive assembly. Among them, each mounting component 120 includes a sleeve 122 penetrating through the longitudinal 112 and the rear cross beam 116 and a mounting soft pad arranged in the sleeve 122. The electric drive assembly is fixed by the mounting soft pad, and the deformation of the mounting soft pad is used to effectively reduce the vibration of the electric drive assembly caused by road unevenness during vehicle driving, which not only improves the driving comfort but also extends the service life of other key components of the vehicle. In this embodiment, three mounting components 120 are provided. Of course, the number can be four, or other numbers. The specific number of the mounting components 120 can be set according to actual needs and will not be specifically limited here.

[0042] In this embodiment, the sleeve 122 is a round tube, and the round tube is welded and fixed to the longitudinal 112 and the rear cross beam 116. Through holes are opened on the longitudinal 112 and the rear cross beam 116, and the round tube is inserted into the through holes and welded to the longitudinal 112 and the rear cross beam 116 by welding to make the round tube fixedly connected to the longitudinal 112 and the rear cross beam 116 firmly. In addition, the cross-sectional area of the longitudinal 112 and the rear cross beam 116 at the position of the round tube installation 132 is much larger than the rest. Specifically, from the installation position 132 to both ends, the cross-sectional area of the longitudinal 112 and the rear cross beam 116 is ensured to ensure the overall strength of the longitudinal 112 and the rear cross beam 116.

[0043] In other embodiments, the round tube and the longitudinal 112 and the rear cross beam 116 can also be fixedly connected by other connection methods, such as threaded connection, or a combination of threaded connection and welding, or other fixing methods, as long as the round tube can be firmly fixed to the longitudinal 112 and the rear cross beam 116.

[0044] In this embodiment, the mounting soft pad is in interference fit with the sleeve 122, and the mounting soft pad can be pressed into the sleeve 122 by pressing, which greatly simplifies the installation method of the mounting soft pad and is convenient for realizing automatic installation.

[0045] In this embodiment, the suspension cushion includes an outer tube 124, a cushion 126, and an inner core 128 that are coaxially sleeved. An installation hole 1282 for fixing the electric drive assembly is formed on the inner core 128. The outer tube 124, the cushion 126, and the inner core 128 are separately provided and connected and fixed by a coaxially sleeved manner. Among them, the cushion 126 is made of an elastic damping material, and the outer tube 124 and the inner core 128 are made of a non-metallic rigid material, such as nylon material. After the electric drive assembly is connected to the installation hole 1282, the force applied to the suspension cushion when the electric drive assembly vibrates will be transmitted layer by layer through the inner core 128, the cushion 126, and the outer tube 124, so that the suspension cushion can undergo triple buffering during vibration reduction, improving the vibration reduction effect. In addition, a positioning groove 1284 is provided in the installation hole 1282. By cooperating and fixing the positioning groove 1284 with the electric drive assembly, the rotation of the electric drive assembly can be avoided.

[0046] A limiting structure is provided between the outer tube 124 and the cushion 126 and between the cushion 126 and the inner core 128. The limiting structure is used to limit the relative rotation between the outer tube 124, the cushion 126, and the inner core 128. The outer tube 124 extends inward from the inner wall surface to form a protrusion 1242, and the cushion 126 is recessed inward from the outer wall surface to form a groove 1264. The protrusion 1242 and the groove 1264 are in a matching shape, and there are two sets of protrusions 1242 and grooves 1264 with different shapes. The four protrusions 1242 and grooves 1264 are arranged at equal intervals along the circumferential direction of the outer tube 124. The inner wall surface of the cushion 126 and the outer surface of the inner core 128 are in a hexagonal shape that is in a matching shape. With such a setting, the mutual rotation between the outer tube 124, the cushion 126, and the inner core 128 can be effectively avoided, improving the stability of the suspension cushion. Of course, in other embodiments, the limiting structure can also be in other forms, as long as the above effects can be achieved, and no specific limitation is made here.

[0047] In addition, after the outer tube 124, the cushion 126, and the inner core 128 are coaxially sleeved and connected, the outer tube 124 and the inner core 128 are fixedly connected to the cushion 126 through a vulcanization process bonding process, further improving the connection stability between the outer tube 124, the cushion 126, and the inner core 128.

[0048] A hollowed-out portion 1262 is provided on the cushion 126. The hollowed-out portion 1262 extends along the axial direction of the sleeve 122. By providing the hollowed-out portion 1262, firstly, the weight of the suspension cushion can be reduced. Secondly, when the suspension cushion undergoes radial deformation to reduce the vibration of the electric drive assembly, a good damping effect can be provided. At the same time, the surface area of the cushion can be increased, which helps with heat dissipation and improves the durability and stability of the suspension structure.

[0049] In this embodiment, an installation space is formed by enclosing between the longitudinal beam 112, the front cross beam 114 and the rear cross beam 116. The length of the suspension cushion is less than the length of the sleeve 122 and is flush with the end face of the sleeve 122 within the installation space. The electric drive assembly is installed within the installation space and is respectively connected and fixed to the three suspension cushions. By means of three-point connection and fixation, the fixation effect on the electric drive assembly can be effectively improved.

[0050] A rear suspension bracket 130 is installed on the suspension cushion on the rear cross beam 116, and the rear suspension bracket 130 is located within the installation space. Four installation positions 132 are provided on the rear suspension bracket 130. Through the four installation positions 132, each component of the suspension structure can be effectively integrated, and the structure of the transition bracket is simpler with fewer components.

[0051] The suspension assembly 120 on the longitudinal beam 112 is arranged at one end close to the front cross beam 114. By setting the position of the suspension assembly 120, the center of gravity of the electric drive assembly can be effectively adjusted, and then the center of gravity of the whole vehicle can be adjusted to a suitable position in cooperation, improving the stability of the whole vehicle.

[0052] This application also provides a vehicle, including the integrated electric vehicle suspension structure as described above.

[0053] By setting the above-mentioned integrated electric vehicle suspension structure, the weight of the whole vehicle can be effectively reduced, the manufacturing cost can be reduced, the production efficiency can be improved, and at the same time, the NVH performance of the suspension and the performance of the subframe 110 are not reduced.

[0054] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0055] The above-described embodiments only express several implementation manners of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several deformations and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the patent protection scope of this application should be subject to the appended claims.
