This assembly usually first presses the bushing into the frame, then pre-assembles the support connected with the bushing to the motor, then falls the motor assembly into the frame, and finally tightens the bushing and the support in sequence with bolts. In this installation process, the biggest challenge is that the motor cannot be accurately dropped into the installation position, and if the bushing inner skeleton mounting hole is directly selected to be enlarged, a series of new problems will be caused. How to ensure that the motor can fall into the target position becomes a new problem to be solved. SUMMARY

[0003] In view of the problems existing in the prior art, the utility model provides a novel suspension and frame assembly structure to solve the above technical problems.

[0004] In order to achieve the above purpose, the utility model adopts the technical scheme of a novel suspension and frame assembly structure, which comprises a damping bushing pressed into a sub-frame; a guide positioning structure is arranged on the inner core of the damping bushing; a motor support is connected to one side of the damping bushing; a matching guide positioning structure is installed on the side of the motor support opposite to the damping bushing; and the matching guide mechanism cooperates with the guide positioning structure to realize the positioning and installation of the motor support and the damping bushing.

[0005] Further, the guide positioning structure comprises two left and right protrusions arranged on the side surface of the inner core of the damping bushing, and the protrusions are connected with the matching guide positioning structure on the motor support.

[0006] Further, the guide positioning structure further comprises a first inclined guide surface arranged on the side surface of the upper end of the inner core of the damping bushing, and the first inclined guide surface is connected with the matching guide positioning structure on the motor support.

[0007] Further, the matching guide positioning structure comprises a second inclined guide surface arranged on one side of the motor support.

[0008] Further, the matching guide positioning structure further comprises a guide groove arranged on one side of the motor support, and the guide groove is used for cooperating with the protrusion to realize positioning and clamping fixation.

[0009] The utility model discloses beneficial effect is: under the condition of satisfying product performance and assembly space, reduce the number of frame support, need not increase additional installation tooling, reduced the installation difficulty, saved production cost, improved production efficiency while guaranteeing the original characteristic of product.

[0015] In order to make the purpose, technical scheme and advantage of the utility model more clear and obvious, below through the drawing and example, the utility model is further detailedly explained.But it should be understood, the specific example described here is only used to explain the utility model, and is not used to limit the scope of the utility model.

[0016] Unless otherwise defined, all technical and scientific terms used herein are same as the meaning understood by the person belonging to the technical field of the utility model, and the terms used in the specification of the utility model in the utility model are only for the purpose of describing the specific example, and are not intended to limit the utility model.

[0017] Figure 1 It is the installation mode of conventional motor suspension: the damping bushing 2 is pressed into the auxiliary frame 1, and the bushing connecting support 3 is installed with the motor through bolt.The motor is fallen into the auxiliary frame with the support, and is connected through bolt through the bushing inner hole and the motor support 3.Due to the fact that the bushing and the support are not well positioned, the installation efficiency is low.

[0018] Figures 2-4The device is shown as a schematic diagram of an optimized device, a new type of suspension and frame assembly structure, comprising a damping bushing 2 pressed into a sub-frame 1, a guide positioning structure 21 is arranged on the inner core of the damping bushing 2, a motor support 3 is connected to one side of the damping bushing 2, a matching guide positioning structure 31 is installed on the side opposite to the damping bushing 2 of the motor support 3, and the matching guide mechanism 31 and the guide positioning structure 21 cooperate to realize the positioning and installation of the motor support 3 and the damping bushing 2.

[0019] Preferably, the guide positioning structure 21 comprises two left and right protrusions 211 arranged on the side surface of the inner core of the damping bushing 2, and the protrusions 211 are connected with the matching guide positioning structure 31 on the motor support 3.

[0020] Preferably, the guide positioning structure 21 further comprises an inclined guide surface one 212 arranged on the side surface of the upper end of the inner core of the damping bushing 2, and the inclined guide surface one 212 is connected with the matching guide positioning structure 31 on the motor support 3.

[0021] Preferably, the matching guide positioning structure 31 comprises an inclined guide surface two 311 arranged on one side of the motor support 3.

[0022] Preferably, the matching guide positioning structure 31 further comprises a guide groove 312 arranged on one side of the motor support 3, and the guide groove 312 is used for positioning and clamping fixation with the protrusion 211.

[0023] The device makes guide positioning structures on the inner core of the damping bushing 2 and matching guide positioning structures on the motor support 3. The guide positioning structures can guide in X / Y / Z three directions at the same time, and the motor is stably placed in the preset position, thereby improving the assembly efficiency and assembly quality.

[0024] The specific installation process is as follows: first, the damping bushing 2 is placed in the sub-frame 1, and then the motor support 3 on one side of the damping bushing 2 is installed from top to bottom, that is, the inclined guide surface two 311 below the motor support 3 first contacts the inclined guide surface one 212 on the inner core of the damping bushing 2, so that the two inclined surfaces first contact, thereby avoiding the collision caused by direct installation, and then the positioning and fixation are realized through the protrusion 211, the guide groove 312 and the contact surface.
