[0032] The following is combined with Figures 1-4 Detailed description of the suspension bracket 1, suspension assembly 10 and vehicle according to embodiments of the present utility model.

[0033] Reference Figure 1 and Figure 2As shown, the suspension bracket 1 according to an embodiment of the present invention includes: a first connecting portion 11 and a second connecting portion 12. The first connecting portion 11 has a first slot 111, a first connecting hole 112, and a second connecting hole 113. The first slot 111 has a first inner wall 1111 and a second inner wall 1112 opposite to each other in a first direction. The first inner wall 1111 and / or the second inner wall 1112 are provided with insertion guide grooves 1113 extending in a second direction. The first connecting hole 112 and the second connecting hole 113 are coaxially opposite to each other in a first direction and both communicate with the first slot 111. The second connecting portion 12 is connected to the first connecting portion 11. The second connecting portion 12 has a second slot 121, a third connecting hole 122, and a fourth connecting hole. The third connecting hole 122 and the fourth connecting hole are coaxially opposite to each other in a first direction and both communicate with the second slot 121. The third connecting hole 122 and the fourth connecting hole are both constructed as waist holes, and the long axis direction of each waist hole is a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. The first direction can be... Figure 1 The left and right directions in the middle, the second direction can be Figure 1 The vertical direction in the middle, and the third direction can be Figure 1 The front and back directions in the middle.

[0034] It should be noted that the suspension bracket 1 can be used in the vehicle's suspension assembly 10. The first connecting part 11 can be connected to the vehicle's powertrain through the power bracket 2 of the suspension assembly 10, and the second connecting part 12 can be connected to the vehicle's body through the body bracket 3 of the suspension assembly 10, thereby realizing the connection of the powertrain to the body. Specifically, the first fastener 4 of the suspension assembly 10 passes through the first connecting hole 112, the power bracket 2, and the second connecting hole 113 to connect the power bracket 2 to the suspension bracket 1. The second fastener 5 of the suspension assembly 10 passes through the third connecting hole 122, the body bracket 3, and the fourth connecting hole to connect the body bracket 3 to the suspension bracket 1. The first fastener 4 can be constructed as a bolt, and the second fastener 5 can include a bolt and a nut.

[0035] It is understood that the first inner wall 1111 and / or the second inner wall 1112 are provided with insertion guide grooves 1113 extending in the second direction, that is, in Figure 1 In the vertical direction, the first inner wall 1111 is provided with an insertion guide groove 1113, or the second inner wall 1112 is provided with an insertion guide groove 1113, or both the first inner wall 1111 and the second inner wall 1112 are provided with insertion guide grooves 1113. When connecting the power bracket 2 and the suspension bracket 1, when the power bracket 2 is inserted into the first slot 111 from top to bottom, the insertion guide groove 1113 can guide the power bracket 2, allowing the power bracket 2 to move in the second direction. This reduces the need for manual adjustment of the movement direction of the power bracket 2 and reduces human error, which is beneficial to improving the assembly efficiency and accuracy of the power bracket 2 and the suspension bracket 1.

[0036] Both the third connecting hole 122 and the fourth connecting hole are constructed as oblong holes, with the long axis of the oblong hole facing upwards, i.e., upwards. Figure 1 In the front-to-rear direction, the relative positions of the suspension bracket 1 and the body bracket 3 are adjustable. When the powertrain is installed to the vehicle body through the suspension assembly 10, the relative positions of the suspension bracket 1 and the body bracket 3 can be adjusted in the long axis direction of the waist hole to absorb assembly errors and manufacturing tolerances of various components. This can effectively absorb the displacement in the third direction generated by the power bracket 2 during installation, reduce the force exerted by the suspension bracket 1 on the power bracket 2 and the body bracket 3 in the front-to-rear direction, and reduce the deformation of the damping rubber used for vibration damping in the power bracket 2 and the body bracket 3. This is beneficial to improving the durability of the power bracket 2 and the body bracket 3, increasing the life of the suspension assembly 10, and ensuring the energy absorption and vibration damping capacity of the damping rubber. This is beneficial to the damping rubber fully absorbing the vibration transmitted from the powertrain to the vehicle body, thereby effectively improving the NVH (Noise, Vibration, Harshness) performance of the vehicle.

[0037] According to the embodiment of this utility model, the suspension bracket 1 is used for the suspension assembly 10 of a vehicle. Its insertion guide groove 1113 can guide the power bracket 2 of the suspension assembly 10, which can reduce assembly time and improve the assembly efficiency of the suspension assembly 10. The third connecting hole 122 and the fourth connecting hole are both constructed as waist holes, which can absorb assembly errors and manufacturing tolerances of various parts, which can improve the life of the suspension assembly 10 and improve the NVH performance of the vehicle.

[0038] In some embodiments of this utility model, a locking part 1114 is provided on the first inner wall 1111 and / or the second inner wall 1112. The locking part 1114 is adapted to abut against the power bracket 2 inserted into the first slot 111 in the second direction, which can realize the positioning of the power bracket 2 and help improve the assembly accuracy of the power bracket 2 and the suspension bracket 1.

[0039] It is understood that a locking part 1114 is provided on the first inner wall 1111, or a locking part 1114 is provided on the second inner wall 1112, or both the first inner wall 1111 and the second inner wall 1112 are provided with locking parts 1114. When the power bracket 2 is installed to the suspension bracket 1, in the second direction, the power bracket 2 can be inserted into the first slot 111 from top to bottom. When the power bracket 2 and the locking part 1114 abut against each other, the locking part 1114 can stop the power bracket 2 and prevent the power bracket 2 from continuing to move downward, so that the power bracket 2 is located in the preset installation position, realizing the automatic positioning of the power bracket 2 without the need to manually adjust the position of the power bracket 2 in the vertical direction. This is beneficial to further improve the assembly efficiency and accuracy of the power bracket 2 and the suspension bracket 1. In addition, the abutment between the power bracket 2 and the locking part 1114 can increase the contact area between the power bracket 2 and the suspension bracket 1, which is beneficial to evenly distribute stress and reduce the risk of local deformation of the power bracket 2 and the suspension bracket 1.

[0040] In some embodiments, refer to Figure 2 As shown, the locking part 1114 can be constructed as a protrusion. When the locking part 1114 abuts against the power support 2 in the second direction, the locking part 1114 can support and stop the power support 2, thereby achieving automatic positioning of the power support 2.

[0041] In other embodiments not shown in the figures, the locking part 1114 may also be configured as a groove, and the power bracket 2 is provided with a locking spring. When the power bracket 2 is inserted downward into the first slot 111, the locking spring can be compressed first. When the locking spring moves to the position corresponding to the locking part 1114, the locking spring can pop out and abut against the bottom of the groove of the locking part 1114, thereby realizing the automatic positioning of the power bracket 2.

[0042] In this embodiment, refer to Figure 2 As shown, locking portions 1114 are provided on both the first inner wall 1111 and the second inner wall 1112. The locking portions 1114 on the first inner wall 1111 and the locking portions 1114 on the second inner wall 1112 can jointly support the power bracket 2, evenly distribute the load, reduce the force on a single locking portion 1114, and thus help reduce the risk of deformation of the locking portion 1114.

[0043] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, the locking part 1114 is a protrusion located within the insertion guide groove 1113, in the first direction, that is... Figure 2In the left-right direction, the thickness T of the locking part 1114 is less than or equal to the groove depth D of the insertion guide groove 1113, and / or, in the second direction, one end of the locking part 1114 used to abut against the power bracket 2 is the abutment end, and the other end of the locking part 1114 is the base end, and the width of the locking part 1114 in the third direction gradually increases from the abutment end to the base end.

[0044] In other words, in the first direction, that is Figure 2 In the left-right direction, the thickness T of the locking part 1114 of the protrusion is less than or equal to the groove depth D of the insertion guide groove 1113, so as to facilitate the machining or casting of the suspension bracket 1.

[0045] Or, in the second direction, that is Figure 1 In the vertical direction, the end of the locking part 1114 that abuts against the power bracket 2 is the abutting end, and the other end of the locking part 1114 is the base end. The width of the locking part 1114 in the third vertical direction gradually increases from the abutting end to the base end. That is, the upper end of the locking part 1114 is the abutting end, and the lower end of the locking part 1114 is the base end. The locking part 1114 is constructed as a trapezoidal block with a wider lower end, which helps to improve the structural stability of the locking part 1114, so that the locking part 1114 can stably and reliably support the power bracket 2. In addition, when the power bracket 2 is provided with a limiting groove that fits into the locking part 1114, the locking part 1114, which is narrower at the top and wider at the bottom, can guide the power bracket 2 when the power bracket 2 is installed from top to bottom.

[0046] Or, in the first direction, that is Figure 2 In the left-right direction, the thickness T of the locking part 1114 is less than or equal to the groove depth D of the insertion guide groove 1113. In the second direction, the end of the locking part 1114 that abuts against the power bracket 2 is the abutting end, and the other end of the locking part 1114 is the base end. The width of the locking part 1114 in the third direction gradually increases from the abutting end to the base end, which is convenient for the suspension bracket 1 to be machined or cast and also helps to improve the structural stability of the locking part 1114.

[0047] In some embodiments of this utility model, one of the first connecting hole 112 and the second connecting hole 113 is a threaded hole, and the other is a smooth hole. For example, if the first connecting hole 112 is a threaded hole and the second connecting hole 113 is a smooth hole, a first fastener 4, constructed as a bolt, can be used to pass through the second connecting hole 113 and the power bracket 2 in sequence and be threaded into the first connecting hole 112. Tightening the first fastener 4 can clamp the power bracket 2 between the first inner wall 1111 and the second inner wall 1112, thereby fixing the power bracket 2 to the suspension bracket 1. Alternatively, the first... The first connecting hole 112 is a smooth hole, and the second connecting hole 113 is a threaded hole. A first fastener 4, which is constructed as a bolt, can be used to pass through the first connecting hole 112 and the power bracket 2 in sequence and engage with the second connecting hole 113 by thread. Tightening the first fastener 4 can clamp the power bracket 2 between the first inner wall 1111 and the second inner wall 1112, so that the power bracket 2 is fixedly connected to the suspension bracket 1. The connection between the power bracket 2 and the suspension bracket 1 is achieved by tightening the first fastener 4. The connection method is simple and can reduce the use of nuts, making it convenient to assemble the power bracket 2 and the suspension bracket 1.

[0048] In some embodiments of this utility model, the suspension bracket 1 is a cast integral part, and the first connecting part 11 and the second connecting part 12 do not need to be connected by fasteners or welding, which helps to reduce the assembly steps of the first connecting part 11 and the second connecting part 12, thereby improving the production efficiency of the suspension bracket 1. Furthermore, the absence of seams between the first connecting part 11 and the second connecting part 12 helps to improve the overall structural strength of the suspension bracket 1, thus facilitating a stable and reliable connection of the powertrain to the vehicle body. Referring to… Figure 2 As shown, in the front-rear direction, the openings of the first slot 111 and the second slot 121 are opposite to each other, which can reduce the risk of interference between the power bracket 2 and the vehicle body bracket 3.

[0049] Reference Figures 1-4 As shown, the suspension assembly 10 according to another embodiment of the present invention includes: a suspension bracket 1, a power bracket 2, a body bracket 3, a first fastener 4, and a second fastener 5. The suspension bracket 1 is the same as the suspension bracket 1 described in the above embodiment. The power bracket 2 is adapted to be connected to the powertrain. The power bracket 2 has a first connecting bushing 21, which is inserted into a first slot 111. The first connecting bushing 21 is guided and engaged with the insertion guide groove 1113 in a second direction. The body bracket 3 is adapted to be connected to the body. The body bracket 3 has a second connecting bushing 31, which is inserted into a second slot 121. The first fastener 4 passes through a first connecting hole 112, a first connecting bushing 21, and a second connecting hole 113. The second fastener 5 passes through a third connecting hole 122, a second connecting bushing 31, and a fourth connecting hole.

[0050] Understandably, the first fastener 4 passes through the first connecting hole 112, the first connecting bushing 21, and the second connecting hole 113, so that the power bracket 2 is connected to the suspension bracket 1 through the first fastener 4. The first fastener 4 can limit the first connecting bushing 21 to prevent the power bracket 2 from detaching. The second fastener 5 passes through the third connecting hole 122, the second connecting bushing 31, and the fourth connecting hole, so that the suspension bracket 1 is connected to the body bracket 3 through the second fastener 5. The second fastener 5 can limit the suspension bracket 1 to prevent the suspension bracket 1 from detaching. This is conducive to the stable and reliable connection of the powertrain to the body through the suspension assembly 10. Furthermore, the first fastener 4 and the second fastener 5 can transmit force, which helps to ensure the continuity of the force transmission path.

[0051] The first connecting bushing 21 and the second connecting bushing 31 can realize the vibration reduction function. Both the first connecting bushing 21 and the second connecting bushing 31 include an outer sleeve, a damping rubber and an inner sleeve. The inner sleeve is located radially inside the outer sleeve. The damping rubber is connected between the inner sleeve and the outer sleeve by vulcanization. The first fastener 4 passes through the inner sleeve of the first connecting bushing 21 and the second fastener 5 passes through the inner sleeve of the second connecting bushing 31. Specifically, when vibration is transmitted from the powertrain to the vehicle body, the damping rubber in the first connecting bushing 21 and the second connecting bushing 31 is deformed under force to absorb energy, thereby reducing the vibration transmitted to the vehicle body and improving the NVH performance of the vehicle.

[0052] According to the embodiment of the present invention, the suspension assembly 10 has a mounting bracket 1113 with a guide groove 1113 that can guide the power bracket 2, which can reduce assembly time and improve the assembly efficiency of the suspension assembly 10. The third connecting hole 122 and the fourth connecting hole are both constructed as waist holes, which can absorb assembly errors and manufacturing tolerances of various parts, which can improve the life of the suspension assembly 10 and improve the NVH performance of the vehicle.

[0053] In some embodiments of this utility model, a locking portion 1114 is provided on the first inner wall 1111 and / or the second inner wall 1112, and a limiting portion 211 corresponding to the locking portion 1114 is provided on the first connecting bushing 21. The locking portion 1114 is inserted into the corresponding limiting portion 211, and the locking portion 1114 and the limiting portion 211 are abutted in the second direction so that the first connecting hole 112, the first connecting bushing 21 and the second connecting hole 113 are coaxial.

[0054] Understandably, when the power bracket 2 is installed onto the suspension bracket 1, in the second direction, the power bracket 2 can be inserted into the first slot 111 from top to bottom. When the power bracket 2 abuts against the locking part 1114, the locking part 1114 can stop the power bracket 2 and prevent the power bracket 2 from moving downward, so that the power bracket 2 is located in the preset installation position. The first connecting hole 112, the first connecting bushing 21 and the second connecting hole 113 are coaxial, realizing automatic positioning of the power bracket 2 without the need for manual adjustment of the position of the power bracket 2. This allows the first fastener 4 to be smoothly inserted into the first connecting hole 112, the first connecting bushing 21 and the second connecting hole 113 in sequence, which is beneficial to improving the assembly efficiency and accuracy of the power bracket 2 and the suspension bracket 1.

[0055] In some embodiments of this utility model, the locking part 1114 is constructed as a protrusion. In the second direction, one end of the locking part 1114 that abuts against the limiting part 211 is the abutting end, and the other end of the locking part 1114 is the base end. The width of the locking part 1114 in the third direction gradually increases from the abutting end to the base end.

[0056] Understandably, referring to Figure 1 As shown, the limiting part 211 is constructed as a groove. From top to bottom, the width (dimension in the front-to-back direction) of the locking part 1114 gradually increases. The upper end of the locking part 1114 is the abutting end, and the lower end of the locking part 1114 is the base end. The locking part 1114 is constructed as a trapezoidal block. When installing the power bracket 2, the power bracket 2 can move from top to bottom. The width of the abutting end is small so that the locking part 1114 can be inserted into the limiting part 211. When disassembling the power bracket 2, the power bracket 2 can move from bottom to top, that is, move in the direction where the width of the locking part 1114 gradually decreases so that the power bracket 2 can be separated from the suspension bracket 1.

[0057] In addition, from the third-party upward direction, the side walls on both the left and right sides of the locking part 1114 can abut against the inner wall of the limiting part 211, which can increase the connection area between the locking part 1114 and the first connecting bushing 21. This is beneficial for the locking part 1114 to stably and reliably support the first connecting bushing 21, reduce the risk of the first connecting bushing 21 shaking, and ensure that vibration energy is effectively transmitted to the first connecting bushing 21 so that the first connecting bushing 21 can fully absorb vibration energy and ensure the energy absorption and vibration reduction performance of the first connecting bushing 21.

[0058] In some embodiments of this utility model, in the circumferential direction of the first connecting hole 112, the locking part 1114 and the limiting part 211 are in a limiting cooperation. The locking part 1114 can effectively prevent the power bracket 2 from rotating relative to the suspension bracket 1, ensuring that the vibration energy is effectively transmitted to the first connecting bushing 21, so that the first connecting bushing 21 can fully absorb the vibration energy and ensure the energy absorption and vibration reduction performance of the first connecting bushing 21.

[0059] In some embodiments of this utility model, during installation, the suspension bracket 1 and the vehicle body bracket 3 are pre-assembled, that is, in... Figure 1 In the left-right direction, the bolt of the second fastener 5 passes through the third connecting hole 122, the second connecting bushing 31 and the fourth connecting hole in sequence from the left side of the suspension bracket 1. On the right side of the suspension bracket 1, the nut is screwed onto the bolt but not tightened, leaving room for adjustment to ensure that the suspension bracket 1 can move relative to the body bracket 3 in the front-rear direction. Then, the suspension bracket 1 and the body bracket 3 are sent to the final assembly workshop as a whole. After the body bracket 3 is screwed onto the body, the power bracket 2 falls with the powertrain. The power bracket 2 is inserted into the first slot 111 from top to bottom. When the power bracket 2 abuts and engages with the locking part 1114, the first fastener 4 passes through the first connecting hole 112 and the first connecting bushing 21 in sequence from the left side of the suspension bracket 1 and is screwed into the second connecting hole 113. First, the first fastener 4 is tightened to assemble the power bracket 2 into place. Then, the nut and bolt of the second fastener 5 are tightened to complete the installation of the suspension assembly 10.

[0060] According to the embodiment of the present invention, the suspension assembly 10 has a plug-in guide groove 1113 and a trapezoidal locking part 1114. During the assembly of the suspension assembly 10, the power bracket 2 can be automatically guided and positioned, saving the time of manual adjustment. The locking part 1114 can limit the height of the power bracket 2 in the second direction, preventing the power bracket 2 from being misaligned during assembly and preventing the first connecting bushing 21 of the power bracket 2 from being subjected to additional force in the second direction (Z direction in the vehicle coordinate system), which is beneficial to increasing the durability of the first connecting bushing 21. At the same time, in the third direction, the suspension bracket 1 has a third connecting hole 122 and a fourth connecting hole with a waist-shaped structure, which can absorb the displacement in the third direction generated when the powertrain falls, preventing the first connecting bushing 21 of the power bracket 2 and the second connecting bushing 31 of the body bracket 3 from being subjected to additional force in the third direction (X direction in the vehicle coordinate system), which is beneficial to increasing the durability of the first connecting bushing 21, so that the first connecting bushing 21 can play a better vibration isolation role, thereby effectively improving the NVH performance of the vehicle.

[0061] The vehicle according to another embodiment of the present invention includes the suspension assembly 10 of the above embodiment.

[0062] According to the vehicle of this utility model embodiment, the insertion guide groove 1113 of the suspension bracket 1 can guide the power bracket 2, which can reduce assembly time and improve the assembly efficiency of the suspension assembly 10. The third connecting hole 122 and the fourth connecting hole are both constructed as waist holes, which can absorb assembly errors and manufacturing tolerances of various parts, which can improve the life of the suspension assembly 10 and improve the NVH performance of the vehicle.

[0063] In some embodiments of this utility model, the vehicle may be a hybrid vehicle or a high-torque gasoline vehicle.
