The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In one aspect of the embodiments of the present invention, a suspension structure is provided, as shown in fig. 1, including a suspension connector 103 and a bracket 102; one end of the suspension connecting piece 103 is used for fixedly connecting the vehicle longitudinal beam 100, the other end of the suspension connecting piece is provided with a first connecting part 104, the first connecting part 104 can deform under stress, and the suspension connecting piece 103 is connected with the power assembly 101 through the first connecting part 104 so as to reduce the vibration of the power assembly 101 through the deformation of the first connecting part 104; a second connecting part 105 fixedly connected with the bracket 102 is arranged at one side of the suspension connecting part 103; the bracket 102 is used to carry parts.

Illustratively, one end of the suspension link 103 is fixedly attached to a longitudinal beam of the vehicle to form a basic load-bearing structure. The first connecting portion 104 at the other end of the suspension connecting member 103 is then fixedly connected to the powertrain 101 of the vehicle, and meanwhile, it should be noted that the first connecting portion 104 has an elastically deformable capability, therefore, under the condition of loading the power assembly 101, when the vehicle longitudinal beam 100 generates different degrees of amplitude along with the external environment, in the case where the amplitude or vibration is transmitted to the powertrain 101 through the suspension link 103 so as to have a certain amplitude, the first connecting portion 104 can be deformed by itself, so that the first connecting portion and the second connecting portion are in non-rigid connection after the vehicle longitudinal beam 100 vibrates, thereby effectively avoiding the easy damage of the connection part, greatly slowing down the transmission of vibration, so that the powertrain 101 of the vehicle can have a relatively stable state, and thus the output is more smooth. Similarly, when the vibration of the external environment is small and the vibration generated by the powertrain 101 is large, the vibration transmitted from the powertrain 101 to the vehicle side member 100 can be reversely reduced, so that the riding experience is better. In addition, the bracket 102 portion which is originally arranged on the first connecting portion 104 is arranged on the second connecting portion 105 of the side wall of the suspension connecting member 103, so that the first connecting portion 104 is effectively helped to share the weight of the bracket 102 portion, the first connecting portion 104 which can be elastically deformed only loads the weight of the power assembly 101 portion of the vehicle in the final structural state, and the fatigue durability of the suspension structure is improved. Meanwhile, the service life of the suspension structure is prolonged, and the maintenance period is shortened.

It should be further noted that, first, the fixed connection between the suspension connecting member 103 and the vehicle longitudinal beam 100, the connection between the first connecting portion 104 and the power assembly 101, and the fixed connection between the second connecting portion 105 and the bracket 102 may be detachable connections (such as screw threads, clamping connections, sockets, etc.), or non-detachable connections (such as welding, bonding, etc.), and the present application does not specifically limit the forms.

Secondly, the suspension connecting member 103 may be one, or two, three, four or more. When one, it is connected to only one side rail of the vehicle; when the number of the two longitudinal beams is two, the two longitudinal beams can be arranged on the longitudinal beams on the two sides of the vehicle in a left-right mode according to the connection mode; when there are three, two longitudinal beams can be arranged on one side, and one longitudinal beam is arranged on the other side; four, five or more of the above-described setting modes may be set in order.

Fourthly, the deformation of the first connecting portion 104 caused by the force means that the first connecting portion 104 deforms to some extent in the process of transmitting the vibration to the powertrain 101 by the vehicle side member 100, thereby absorbing a part of the vibration; alternatively, the first connecting portion 104 may be deformed to absorb a portion of the vibration while the powertrain 101 transmits the vibration generated by itself to the vehicle side member 100.

As shown in fig. 1, two left and right side members of a vehicle are shown (a first side member and a second side member in the following embodiments, which will be described with reference to the first side member and the second side member for the sake of description uniformity). Meanwhile, one end of the first suspension connecting member 103 (i.e. the suspension connecting member 103 connected to the first longitudinal beam on the left side in fig. 1) is fixedly connected to the first longitudinal beam, and the other end is connected to one end of the powertrain 101 in a surface-contact multipoint fixed connection manner, so that the strength of connection and fixation can be improved, and sufficient connection stability can be ensured. Similarly, one end of the second suspension connecting member 103 (i.e. the suspension connecting member 103 connected to the second longitudinal beam on the right in fig. 1) is fixedly connected to the second longitudinal beam, and the other end is connected to the other end of the powertrain 101 in a surface-contact multipoint fixed connection manner. The side walls of the first suspension connecting piece 103 and the second suspension connecting piece 103, which are close to the upper ends in fig. 1, are respectively provided with the second connecting portion 105, the second connecting portion 105 is used as a support, the upper end of the second connecting portion 105 is fixedly connected with the bracket 102, and meanwhile, the bracket 102 can be provided with a charger, a storage battery and other parts. In addition, the height of the second connecting portion 105 can be increased or decreased adaptively according to the specific layout of the vehicle body, so that a flexible setting mode of raising or lowering the bracket 102 is achieved, and the optimal arrangement of various parts in the vehicle body is facilitated. The bracket 102 is separated from the power assembly 101, and more parts can be arranged on the bracket 102, which is more beneficial to the arrangement of the chassis.

Optionally, the suspension connector 103 includes a housing 1042 having an inner cavity, and an opening communicating with the inner cavity is further disposed on the housing 1042; the first connection portion 104 is fixedly disposed in the inner cavity through the opening.

The first connecting portion 104 is a connecting member between the housing 1042 and the power assembly 101, so that one end of the first connecting portion 104 extends into the inner cavity of the housing 1042 through the first opening and is fixed (either in a detachable or non-detachable manner) on the inner wall of the housing 1042, thereby forming a reliable connecting and supporting mechanism for connecting the load power assembly 101. Meanwhile, the second connecting portion 105 is correspondingly disposed on the sidewall of the housing 1042, for example, in fig. 2, at a position above the sidewall of the housing 1042 with the suspension connecting member 103 in the placing position. Therefore, the power assembly 101 is loaded by the first connecting part 104 which can be elastically deformed, and the bracket 102 is loaded by the second connecting part 105, so that the load of the first connecting part 104 is reduced, the rapid reduction of the fatigue resistance and the durability of the first connecting part 104 is avoided, the original vibration reduction capability is lost, and the reliability of the connecting support is reduced.

Optionally, the first connection portion 104 includes a cushion 10432 and a support 1043; the buffer member 10432 is located in the inner cavity, a mounting hole 10433 is arranged at the center of the buffer member 10432, one end of the supporting member 1043 extends into the mounting hole 10433 to be fixedly connected with the buffer member 10432, and the other end is fixedly connected with the power assembly 101.

Illustratively, the first connecting portion 104 may include a cushion 10432 and a support 1043. The buffering member 10432 in this embodiment may be, as shown in fig. 3, formed by a cylinder with a better deformation capability, and meanwhile, the outer circumferential sidewall of the cylinder and the inner wall of the housing 1042 (i.e., the sidewall of the inner cavity) are disposed in a fully adaptive manner, so that the cylinder and the inner wall are closely attached together, and may be formed by directly stamping the inner wall of the housing 1042, or may be fixedly disposed in a subsequent bonding or screwing manner to meet a sufficient strength requirement. In order to facilitate the installation of the supporting member 1043, an installation hole 10433 is provided in the center of the buffering member 10432, and as shown in fig. 4, one end of the supporting member 1043 is pressed into the buffering member 10432 through the installation hole 10433, so that the supporting member 1043 and the buffering member 10432 form a first connection portion 104 which is reliable and has good stability. It should be noted that the connection relationship between the supporting member 1043 and the buffering member 10432 may be fixed and connected together in a manner of clamping, interference fit, and the like, and the application does not specifically limit the connection relationship.

Optionally, a buffer slot 10435 is disposed around the buffer member 10432 with the mounting hole 10433 as a center, and a buffer protrusion 10436 is disposed in the buffer slot 10435 toward the mounting hole 10433.

For example, in order to provide better damping performance, a buffer groove 10435 is further dug on the buffer 10432. As shown in fig. 4, there are three buffer slots 10435, and the three buffer slots 10435 are not communicated with each other, so that the deformability can be further improved on the basis of providing enough support for the supporting member 1043 in the mounting hole 10433, and a good vibration damping effect can be achieved. Meanwhile, in order to prevent the power assembly 101 or the vehicle side member 100 from shaking for a long time during vibration filtering and not to solve the vibration well, a buffering protrusion 10436 is further provided in the buffering groove 10435, and in other embodiments, the buffering protrusion 10436 may be further provided in the buffering groove 10435 in any direction. The direction setting of the protruding 10436 of buffering towards mounting hole 10433 in this embodiment, can be better when mounting hole 10433 is deformed to a certain direction along with supporting piece 1043, can be through the mode of butt on protruding 10436 of buffering, the too big deformation of fine restriction range, prevent that bolster 10432 from damaging, simultaneously, also can provide better support capacity.

For example, in order to better provide stable connection and support capability for the powertrain 101 and flexibly adjust the position of the powertrain 101 according to the layout of the vehicle body, the supporting member 1043 may further include a supporting arm 10434 and an extending portion 1041, and one end of the supporting arm 10434 extends into the mounting hole 10433 and is fixedly disposed with the buffer member 10432. Meanwhile, an extension portion 1041 is fixedly connected to the other end of the supporting arm 10434, as shown in fig. 1, one end of the extension portion 1041 is fixedly connected to the supporting arm 10434 in a threaded manner, and at the same time, the extension portion 1041 extends in a direction away from the bracket 102 (fixedly connected to the second connecting portion 105), so that a more abundant installation space can be provided for the powertrain 101. In order to make the connection more stable, the extension portion 1041 may also adopt an arc-shaped structure, which is first formed by approaching the power assembly 101 to form a transition section, and then extended to form a connection section with a suitable adaptability to an end face of the power assembly 101.
