Referring to fig. 1, 4 and 5, in a specific embodiment, the limiting groove 132 may define two movement directions of the suspension bracket 13 relative to the base 11, so that the movement amplitude of the suspension bracket 13 relative to the base 11 may be reduced to define the vibration amplitude of the powertrain, so that the suspension mechanism 1 tends to be miniaturized, and detailed description of the specific implementation is omitted herein. In yet another specific embodiment, the limiting groove 132 may define three movement directions of the suspension bracket 13 relative to the base 11, so as to further reduce the movement amplitude of the suspension bracket 13 relative to the base 11, so that the suspension mechanism 1 tends to be miniaturized, and the specific implementation will not be repeated here.

Referring to fig. 1, 4 and 5, in a specific embodiment, the elastic member 123 further includes a second limiting portion 1234, the second limiting portion 1234 is connected to the peripheral side of the elastic body 1232, and disposed towards the base 11 and spaced from the base 11, and the spacing between the second limiting portion 1234 and the base 11 is used for limiting the travel of the suspension bracket 13 along the height direction Z of the base 11 in the direction approaching to the base 11, so as to prevent the suspension bracket 13 from directly contacting the base 11 to generate loud noise.

Referring to fig. 1, 4 and 5, in a specific embodiment, a plurality of limiting protrusions 1235 are disposed on a surface of the first limiting portion 1233 facing the wall of the limiting groove 132, and the limiting protrusions 1235 can prevent the surface of the first limiting portion 1233 from directly abutting against the wall of the limiting groove 132 when the suspension bracket 13 moves relative to the base 11, and buffer the impact force between the first limiting portion 1233 and the wall of the limiting groove 132, so as to reduce the force transmitted to the base 11, prevent the base 11 from generating resonance, and reduce noise. Further, since the limiting protrusion 1235 can be abutted with the groove wall of the limiting groove 132 when the suspension bracket 13 moves relative to the base 11, the contact area between the first limiting portion 1233 and the groove wall of the limiting groove 132 during collision can be reduced, and further the noise can be further reduced, so as to improve the riding comfort of the vehicle.

Referring to fig. 1, 4 and 5, in a specific embodiment, a plurality of spacing protrusions 1235 are disposed on a surface of the second spacing portion 1234 facing the base 11, and the spacing protrusions 1235 can prevent the surface of the second spacing portion 1234 from directly abutting against the surface of the base 11 and buffer the impact force between the second spacing portion 1234 and the base 11, so as to reduce the force transferred to the base 11, prevent the base 11 from generating resonance, and reduce noise. Further, since the limiting protrusion 1235 can be abutted against the surface of the base 11, the contact area between the second limiting portion 1234 and the base 11 during the collision can be reduced, and thus the noise can be further reduced, so as to improve the riding comfort of the vehicle.

Referring to fig. 1 and 3, in a specific embodiment, the base 11 has a reinforcing groove 114, the reinforcing groove 114 is disposed on two surfaces of the base 11 along the length direction X thereof, and the reinforcing groove 114 can increase the structural strength of the base 11, so as to reduce the volume of the base 11 and the volume of the suspension mechanism 1. And since the base 11 is smaller, the adaptability of the elastic member 123 to deformation can be increased.

Referring to fig. 1 and 3, in a specific embodiment, the base 11 further has reinforcing ribs 115, the reinforcing ribs 115 are disposed on two surfaces of the base 11 along the width direction Y, and the structural strength of the base 11 can be increased by using the reinforcing ribs 115, so that the volume of the base 11 can be reduced, and the volume of the suspension mechanism 1 can be reduced.

Referring to fig. 1 and 2, in a specific embodiment, the main spring assembly 12 further includes a liquid chamber device 125, such that the suspension mechanism 1 is a hydraulic suspension mechanism, the liquid chamber device 125 includes a liquid chamber body 1251 and a guide block 1252, the guide block 1252 is connected to the liquid chamber body 1251, a side of the suspension bracket 13 away from the inner core 124 has a mounting groove 133 and a guide groove 134 (see fig. 1 and 4), the liquid chamber body 1251 is protruding in the mounting groove 133, the guide groove 134 is in communication with the mounting groove 133, and the guide block 1252 is embedded in the guide groove 134 to provide positioning guiding function for mounting the liquid chamber device 125. The liquid chamber body 1251 is used for storing a damping liquid, such as silicone oil or ethylene glycol, to prevent the damping liquid from freezing in a low-temperature environment, and the specific liquid chamber body 1251 may include an upper flow channel plate (not shown in the figure), a lower flow channel plate (not shown in the figure), a cup skeleton (not shown in the figure), a decoupling film (not shown in the figure), and a liquid sealing bead (not shown in the figure), and the guide block 1252 is disposed on the cup skeleton. Wherein, the leather cup skeleton, the leather cup and the elastic piece 123 can form a closed vacuum liquid chamber, damping liquid generates damping through a flow passage formed by the flow passage plate and the decoupling film, and can absorb energy under the working condition of large amplitude of the power assembly, thereby reducing and delaying the response of the power assembly.

In a second aspect, the embodiment of the application further provides a vehicle, including a body longitudinal beam, a power assembly and a suspension mechanism 1, wherein a base 11 is connected with the body longitudinal beam, and a suspension bracket 13 is connected with the power assembly to support the power assembly by using the suspension mechanism 1 and to damp the power assembly so as to improve riding comfort.
