[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Combine the following Figure 1-Figure 4 A power mount assembly of the present invention is described.

[0023] like Figures 1 to 4 As shown, the present invention provides a power suspension assembly 1, comprising: a suspension cushion 11 and a bracket 12. The suspension cushion 11 is used to be connected to the power assembly 2 and the frame 3 respectively. A first through hole is provided at one end of the bracket 12, a first flexible bushing 121 is provided in the first through hole, a first connecting member is inserted in the first flexible bushing 121, and the first connecting member is connected to the suspension cushion 11. A second through hole is provided at the other end of the bracket 12, a second flexible bushing 122 is provided in the second through hole, a second connecting member is inserted in the second flexible bushing 122, and the second connecting member is used to be connected to the frame 3. The extension direction of the first through hole is perpendicular to the extension direction of the second through hole.

[0024] In this embodiment, the suspension cushion 11 is disposed between the powertrain 2 and the frame 3, and the suspension cushion 11 is connected to the powertrain 2 and the frame 3 to form a suspension connection between the powertrain 2 and the frame 3. The suspension cushion 11 can play a role in buffering and reducing vibration between the powertrain 2 and the frame 3.

[0025] At the same time, by setting a bracket 12, both ends of the bracket 12 are connected to the suspension cushion 11 and the frame 3 respectively, so as to assist the suspension cushion 11 in supporting the powertrain 2 and enhance the vibration reduction effect of the suspension cushion 11 between the powertrain 2 and the frame 3.

[0026] Specifically, a first flexible bushing 121 is provided in the first through hole at one end of the bracket 12, and the first flexible bushing 121 is sleeved on the first connecting piece connected to the power assembly 2. When the power assembly 2 vibrates, the first flexible bushing 121 can deform and buffer between the hole wall of the first through hole and the first connecting piece to achieve a vibration reduction effect; similarly, a second flexible bushing 122 is provided in the second through hole at the other end of the bracket 12, and the second flexible bushing 122 can also deform and buffer between the hole wall of the second through hole and the second connecting piece to achieve a vibration reduction effect. The extension directions of the first through hole and the second through hole are perpendicular to each other, and the contact surfaces of the first flexible bushing 121 and the first connecting piece and the contact surfaces of the second flexible bushing 122 and the second connecting piece are also oriented in different directions, so that the first flexible bushing 121 and the second flexible bushing 122 can be used to buffer vibrations in different directions, thereby improving the suspension decoupling rate of the power assembly 2 and achieving a better vibration reduction effect.

[0027] The power suspension assembly 1 of the present invention connects the powertrain 2 and the frame 3 through the suspension pad 11, so as to suspend and install the powertrain 2 on the frame 3, and the suspension pad 11 has a certain buffering and vibration reduction function; at the same time, by connecting the bracket 12 between the suspension pad 11 and the frame 3, the two ends of the bracket 12 are respectively provided with a first through hole and a second through hole whose extension directions are perpendicular to each other, and the first through hole and the second through hole are respectively provided with a first flexible bushing 121 and a second flexible bushing 122, the first flexible bushing 121 can buffer and reduce vibration between the first connecting piece connecting the suspension pad 11 and the wall of the first through hole, and the second flexible bushing 122 can buffer and reduce vibration between the second connecting piece connecting the frame 3 and the wall of the second through hole, thereby realizing buffering and vibration reduction of the powertrain 2 and the frame 3 in different directions, which can effectively improve the suspension decoupling rate of the powertrain 2, and have a better vibration reduction effect, and effectively solve the defect of insufficient shock absorption capacity of the rear suspension pad in the prior art.

[0028] In some embodiments, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first flexible bushing 121 is provided with a first sleeve hole 1211 and a first vibration-damping hole 1212. The second flexible bushing 122 is provided with a second sleeve hole 1221 and a second vibration-damping hole 1222. The first sleeve hole 1211 is located on the central axis of the first flexible bushing 121, the first connecting member is plugged into the first sleeve hole 1211, and the first vibration-damping hole 1212 and the first sleeve hole 1211 are arranged at intervals along the first direction. The second sleeve hole 1221 is located on the central axis of the second flexible bushing 122, the second connecting member is plugged into the second sleeve hole 1221, and the second vibration-damping hole 1222 and the second sleeve hole 1221 are arranged at intervals along the second direction. The first direction is perpendicular to the plane on which the second connecting member is provided on the frame 3 (such as Figure 1 and Figure 3The second direction is parallel to the plane of the frame 3 provided with the second connecting member (as shown in the X-axis); Figure 1 and Figure 3 The Y axis is shown in the figure).

[0029] In this embodiment, a first sleeve hole 1211 and a first vibration damping hole 1212 are provided on the first flexible bushing 121, the first sleeve hole 1211 is used to plug in the first connecting member, the outer wall of the first connecting member abuts against the hole wall of the first sleeve hole 1211, the first vibration damping hole 1212 and the first sleeve hole 1211 are arranged at intervals along the first direction to increase the flexibility of the first flexible bushing 121 along the first direction, when the powertrain 2 vibrates relative to the frame 3 along the first direction, the first flexible bushing 121 can better buffer and reduce vibration between the bracket 12 and the powertrain 2, thereby blocking the vibration transmission between the powertrain 2 and the frame 3 along the first direction.

[0030] Similarly, by providing a second sleeve hole 1221 and a second vibration damping hole 1222 on the second flexible bushing 122, the second sleeve hole 1221 is used to plug in the second connecting member, the outer wall of the second connecting member abuts against the hole wall of the second sleeve hole 1221, and the second vibration damping hole 1222 and the second sleeve hole 1221 are arranged at intervals along the second direction to increase the flexibility of the second flexible bushing 122 along the second direction. When the powertrain 2 vibrates relative to the frame 3 along the second direction, the first flexible bushing 121 can better buffer and reduce vibration between the bracket 12 and the frame 3, thereby blocking the vibration transmission between the powertrain 2 and the frame 3 along the second direction.

[0031] At the same time, the first direction and the second direction are perpendicular to each other, so that the first flexible bushing 121 and the second flexible bushing 122 can be used to buffer and block vibration conduction in different directions, so as to improve the suspension decoupling rate of the powertrain 2 and achieve a better vibration reduction effect.

[0032] Furthermore, in some embodiments, Figure 3 As shown, there are two first vibration-damping holes 1212 , and the two first vibration-damping holes 1212 are respectively arranged on both sides of the first sleeve hole 1211 along the first direction.

[0033] In this embodiment, a first vibration damping hole 1212 is respectively provided on both sides of the first sleeve hole 1211 along the first direction. When the power assembly 2 vibrates along the first direction relative to the frame 3, the power assembly 2 will drive the first connecting member to move toward both sides relative to the first sleeve hole 1211. The first vibration damping holes 1212 on both sides of the first sleeve hole 1211 can improve the flexibility of the structure on both sides of the first sleeve hole 1211, thereby improving the buffering and vibration reduction effect of the first flexible bushing 121.

[0034] It is understood that in some embodiments, Figure 4As shown, there are two second vibration-damping holes 1222 , and the two second vibration-damping holes 1222 are respectively disposed on two sides of the second sleeve hole 1221 along the second direction.

[0035] In this embodiment, by respectively arranging two second vibration-damping holes 1222 on both sides of the second sleeve hole 1221 along the second direction, when the power assembly 2 vibrates along the second direction relative to the frame 3, the power assembly 2 will drive the second connecting member to move toward both sides relative to the second sleeve hole 1221. The second vibration-damping holes 1222 on both sides of the second sleeve hole 1221 can improve the flexibility of the structure on both sides of the second sleeve hole 1221, thereby improving the buffering and vibration reduction effect of the second flexible bushing 122.

[0036] In some embodiments, when the deflection of the bracket 12 along the first direction is less than or equal to the first deflection, there is a gap between the hole walls on the opposite sides of the first vibration damping hole 1212 along the first direction; when the deflection of the bracket 12 along the first direction is greater than the first deflection, the first flexible bushing 121 is squeezed by the first connecting member and the inner wall of the first through hole, so that the hole walls on the opposite sides of one of the first vibration damping holes 1212 along the first direction abut against each other.

[0037] In this embodiment, it is understandable that the load along the first direction borne by the bracket 12 is positively correlated with the deflection of the bracket 12 along the first direction. When the deflection of the bracket 12 along the first direction is less than or equal to the first deflection, there is a gap between the two opposite side hole walls of the first vibration damping hole 1212 along the first direction, so that the first flexible bushing 121 still has a large flexibility along the first direction to block the vibration transmission between the power assembly 2 and the frame 3 along the first direction; when the deflection of the bracket 12 along the first direction is greater than the first deflection, the power assembly 2 drives the first connecting member to move to one side of the first sleeve hole 1211, and squeezes the first vibration damping hole 1212 on this side, so that the two side hole walls of the first vibration damping hole 1212 abut against each other, thereby reducing the flexibility of the first flexible bushing 121 and enhancing the rigidity, thereby providing effective support for the power assembly 2, so as to control the position of the power assembly 2 in the first direction.

[0038] As can be seen from the above, by reasonably designing the structure and size of the bracket 12 and the first flexible bushing 121, the first deflection can meet the design requirements. When the load in the first direction is small, there is a gap between the two opposite hole walls of the first vibration-damping hole 1212 along the first direction, and the first flexible bushing 121 has high flexibility and good vibration reduction effect; when the load in the first direction is large, the two opposite hole walls of the first vibration-damping hole 1212 along the first direction abut against each other, and the first flexible bushing 121 has high rigidity and can cooperate with the suspension cushion 11 to control the position of the powertrain 2 in the first direction.

[0039] Specifically, in some embodiments, the first deflection is 60% of the maximum deflection of the bracket 12 along the first direction.

[0040] In some embodiments, when the deflection of the bracket 12 along the second direction is less than or equal to the second deflection, there is a gap between the two opposite side hole walls along the second direction of the second vibration-damping hole 1222. When the deflection of the bracket 12 along the second direction is greater than the second deflection, the second flexible bushing 122 is squeezed by the second connecting member and the inner wall of the second through hole, so that the two side hole walls of one of the second vibration-damping holes 1222 along the second direction abut against each other.

[0041] In this embodiment, it is understandable that the load along the second direction borne by the bracket 12 is positively correlated with the deflection of the bracket 12 along the second direction. When the deflection of the bracket 12 along the second direction is less than or equal to the second deflection, there is a gap between the hole walls on the two opposite sides of the second vibration damping hole 1222 along the second direction, so that the second flexible bushing 122 still has greater flexibility along the second direction to block the vibration transmission between the power assembly 2 and the frame 3 along the second direction; when the deflection of the bracket 12 along the second direction is greater than the second deflection, the frame 3 drives the second connecting member to move to one side of the second sleeve hole 1221, and squeezes the second vibration damping hole 1222 on this side, so that the hole walls on both sides of the second vibration damping hole 1222 abut against each other, thereby reducing the flexibility of the second flexible bushing 122 and enhancing its rigidity, thereby providing effective support for the power assembly 2, so as to control the position of the power assembly 2 in the second direction.

[0042] As can be seen from the above, by reasonably designing the structure and size of the bracket 12 and the second flexible bushing 122, the second deflection can meet the design requirements. When the load in the second direction is small, there is a gap between the hole walls on the two opposite sides of the second vibration damping hole 1222 along the second direction, and the second flexible bushing 122 has high flexibility and good vibration damping effect; when the load in the second direction is large, the hole walls on the two opposite sides of the second vibration damping hole 1222 along the second direction abut against each other, and the second flexible bushing 122 has high rigidity and can cooperate with the suspension cushion 11 to control the position of the powertrain 2 in the second direction.

[0043] Specifically, in some embodiments, the second deflection is 60% of the maximum deflection of the bracket 12 along the second direction.

[0044] In some embodiments, Figure 3 As shown, the first vibration-damping hole 1212 is an arc-shaped hole, and the first vibration-damping hole 1212 and the first sleeve hole 1211 are concentrically arranged.

[0045] In this embodiment, by setting the first vibration damping hole 1212 as an arc-shaped hole concentric with the first sleeve hole 1211, when the first vibration damping hole 1212 is squeezed by the first connecting member and the inner wall of the first through hole so that the hole walls on both sides of the first vibration damping hole 1212 abut against each other, the two arc-shaped hole walls of the first vibration damping hole 1212 can fully abut against each other and have a larger contact area, thereby more effectively playing a supporting role between the bracket 12 and the power assembly 2.

[0046] It is understood that in some embodiments, Figure 4 As shown, the second vibration-damping hole 1222 is an arc-shaped hole, and the second vibration-damping hole 1222 and the second sleeve hole 1221 are concentrically arranged.

[0047] In this embodiment, by setting the second vibration damping hole 1222 as an arc hole concentric with the second sleeve hole 1221, when the second vibration damping hole 1222 is squeezed by the second connecting member and the inner wall of the second through hole so that the hole walls on both sides of the first vibration damping hole 1212 abut against each other, the two arc hole walls of the second vibration damping hole 1222 can fully abut against each other and have a larger contact area, thereby more effectively playing a supporting role between the bracket 12 and the frame 3.

[0048] Optionally, in some embodiments, Figure 3 As shown, the bracket 12 is provided with a strip hole 123 so that the difference between the natural frequency of the bracket 12 and the upper and lower limits of the modal range of the powertrain 2 and the upper and lower limits of the modal range of the frame 3 is greater than 50 Hz.

[0049] It is understandable that both the powertrain 2 and the frame 3 have multiple vibration points, and the natural frequencies of the various vibration points are different. The modal range of the powertrain 2 is the range of the natural frequencies of all vibration points of the powertrain 2, and the modal range of the frame 3 is the range of the natural frequencies of all vibration points of the powertrain 2. By providing the strip hole 123 in the bracket 12, the natural frequency of the bracket 12 and the upper and lower limits of the modal range of the powertrain 2 and the upper and lower limits of the modal range of the frame 3 are greater than 50 Hz, so as to play a role in vibration isolation between the powertrain 2 and the frame 3, and avoid resonance between the powertrain 2 and the frame 3.

[0050] Specifically, in some embodiments, the natural frequency of the bracket 12 is greater than or equal to 600 Hz and less than or equal to 700 Hz. By setting the natural frequency of the bracket 12 between 600 Hz and 700 Hz, a suitable interval can be provided between the upper and lower limits of the modal range of the powertrain 2 and the upper and lower limits of the modal range of the frame 3, so as to achieve a vibration isolation effect between the powertrain 2 and the frame 3, and avoid resonance between the powertrain 2 and the frame 3.

[0051] In some embodiments, Figure 1 and Figure 2 As shown, the connection surface between the suspension cushion 11 and the frame 3 and the connection position between the second connecting member and the frame 3 are not coplanar.

[0052] In this embodiment, by arranging the connection surface between the suspension cushion 11 and the frame 3 and the connection position between the second connecting member of the bracket 12 and the frame 3 on different planes, it is beneficial to improve the suspension decoupling rate of the powertrain 2 and the frame 3 in different directions, so as to improve the vibration reduction effect between the powertrain 2 and the frame 3 and extend the life of the frame 3.

[0053] Specifically, in some embodiments, the suspension cushion 11 includes a base and an annular portion connected to each other, wherein the base is used to be fixedly connected to the frame 3, and the annular portion is used to be sleeved on the powertrain 2. A first through hole is provided at one end of the bracket 12, and a first flexible bushing 121 is provided in the first through hole, and a first connector is inserted in the first flexible bushing 121, and the first connector is connected to the annular portion. A second through hole is provided at the other end of the bracket 12, and a second flexible bushing 122 is provided in the second through hole, and a second connector is inserted in the second flexible bushing 122, and the second connector is used to connect to the frame 3. The extension direction of the first through hole is perpendicular to the extension direction of the second through hole.

[0054] The power suspension assembly 1 of the present invention can increase the suspension decoupling rate of the power assembly 2 and the frame 3 to 90%, has good vibration reduction and noise reduction effects, and can effectively increase the service life of the frame 3.

[0055] In some specific embodiments, a plurality of screw holes are provided on the base, and screw holes are also provided one by one corresponding to the screw holes on the suspension cushion 11 of the frame 3, and the suspension cushion 11 and the frame 3 are connected by bolts.

[0056] The first connecting member and the second connecting member at both ends of the bracket 12 may also be bolts connected to the screw holes on the frame 3 .

[0057] On the other hand, the present invention further provides a vehicle, comprising: a power assembly 2, a vehicle frame 3 and a power suspension assembly 1 as described in any of the above embodiments; the power assembly 2 is connected to the vehicle frame 3 via the power suspension assembly 1.

[0058] The vehicle of the present invention, by adopting the power suspension assembly 1 in the above embodiment, also has the advantages of the above power suspension assembly 1, which will not be described in detail here.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
