In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

In one embodiment, referring to fig. 1, a subframe structure 100, the subframe structure 100 includes: a main body 110, a first bracket 120, and a second bracket 130. The first bracket 120 and the second bracket 130 are disposed on the main body 110 at an interval, and the first mounting portion 140 and the second mounting portion 150 are disposed on the first bracket 120 and the second bracket 130. The first mounting portion 140 is used to mount a vehicle body. The second mounting portion 150 is used for mounting a suspension.

In the auxiliary frame structure 100, during installation, the vehicle body and the suspension are both erected on the first bracket 120 and the second bracket 130, so that the vehicle body and the suspension are stressed uniformly, and the vehicle body and the suspension are both in a stable state on the main body 110; after erection, the vehicle body is fixedly connected with the first mounting parts 140 on both sides and the suspension is fixedly connected with the second mounting parts 150 on both sides, so that the vehicle body and the suspension are stably fixed on the first bracket 120 and the second bracket 130. Because the mounting points of the vehicle body and the suspension are integrated on the first support 120 and the second support 130 at the same time, the mounting structures of the vehicle body and the suspension are unified into a whole, the design of the auxiliary frame structure 100 is effectively simplified, the whole space occupation of the auxiliary frame structure 100 is reduced, and the mounting operation of the vehicle body and the suspension is convenient. In addition, the installation of the automobile body and the installation of the suspension are combined into a whole, so that the number of parts is reduced, the whole weight of the auxiliary frame structure 100 is reduced, and the light weight of the automobile is realized.

The first mounting portion 140 and the second mounting portion 150 may be configured as holes; convex structures are also possible. The convex structure is a bolt, a screw rod or a screw structure welded or screwed on the first bracket 120 or the second bracket 130. When the first mounting portion 140 and the second mounting portion 150 are both convex structures, additional purchase or preparation of fixing parts such as bolts or screws is not required.

It should be further noted that there are various connection manners of the first bracket 120 and the second bracket 130 on the main body 110, and this embodiment is not particularly limited, for example: the connection mode of the first bracket 120 and the second bracket 130 on the main body 110 is an integral forming mode, welding, clamping, pin joint, riveting or bolt connection, etc. Wherein, the integrated forming mode can be die casting, extrusion forming and other integrated forming processes. In addition, the suspension of the embodiment is an automotive powertrain for reducing and controlling the transmission of engine vibration and supporting, and is mainly divided into a traditional pure rubber suspension and a hydraulic suspension, and since the structure of the suspension is not an improved object of the embodiment, the specific structure of the suspension is not described in detail here, and reference can be directly made to the existing product.

Further, referring to fig. 1, the first mounting portion 140 is a first mounting hole 141. The first mounting hole 141 is provided to be opposed to a mounting hole on the vehicle body.

In one embodiment, referring to fig. 1, one end of the first sleeve 160 extends out of the first mounting hole 141, and a portion of the first sleeve 160 extending out of the first mounting hole 141 is used to extend into a mounting sleeve on a vehicle body. When the vehicle body is assembled to the first bracket 120 and the second bracket 130, respectively, one end of the first bushing 160 extends into the mounting bushing on the vehicle body, so that the shearing force between the vehicle body and the first bracket 120 or the second bracket 130 acts directly on the first bushing 160. When the automobile collides, the first sleeve 160 is stressed on the side wall of the mounting sleeve of the automobile body, so that the bolt or the screw is prevented from losing efficacy due to excessive shearing force, and the collision safety of the automobile is improved.

In one embodiment, referring to fig. 1, the second mounting portion 150 is a second mounting hole 151. The second sleeve 170 is sleeved in the second mounting hole 151. The second bushing 170 is used for a bolt or a screw to penetrate to fix the suspension. In the process of fixing and suspending, the second sleeve 170 is sleeved in the second mounting hole 151 in advance, so that the bolt or the screw is positioned in the second sleeve 170 when being screwed with the vehicle body, and the bolt or the screw is prevented from directly contacting with the hole wall of the second mounting hole 151 to cause structural abrasion easily. Meanwhile, the second sleeve 170 is additionally arranged in the second mounting hole 151, so that the bolt or the screw can be limited and guided, and the bolt or the screw can be stably connected between the auxiliary frame structure 100 and the vehicle body.

In order to improve structural stability and sealing performance, after the second sleeve 170 is inserted into the second mounting hole 151, structural glue may be applied or welded between the second sleeve 170 and the hole wall of the second mounting hole 151.
