[0033] Please also read Figures 1 to 5 , the mounting frame of the electric control structure and the transmission assembly provided by the utility model are now described. The mounting frame of the electric control structure includes a fixing part 1, a mounting leg 2 and a vibration damping part 3, the electric control structure is mounted on the fixing part 1; the mounting leg 2 is connected to the fixing part 1, the mounting leg 2 has a mounting position connected to the body part, and the mounting leg 2 forms a buffer space between the fixing part 1 and the body part; the vibration damping part 3 is arranged at the mounting position, and the vibration damping part 3 alleviates the vibration force between the mounting leg 2 and the body part.

[0034] Compared with the prior art, the mounting frame of the electric control structure provided by the utility model has a fixing part 1 connected to the electric control structure, fixing and providing support force to the electric control structure, and a mounting leg 2 fixed to the vehicle body component, which provides support force to the fixing part 1 on the one hand, and forms a buffer space between the mounting leg 2 and the vehicle body component on the other hand, providing a reserved space for the fixing part 1, so as to avoid the fixing part 1 from vibrating or deforming when the electric control structure shakes, thereby causing vibration of the vehicle body component and causing abnormal noise in the vehicle. A vibration damping part 3 is arranged at the mounting position of the mounting leg 2. After the fixing part 1 is subjected to force, the vibration force is transmitted to the mounting position through the mounting leg 2. The vibration damping part 3 alleviates the vibration force, so as to avoid deformation or damage of the vehicle body component due to the vibration force. At the same time, the vibration damping part 3 can also reduce the noise generated by the vibration force, thereby improving the NVH performance of the whole vehicle.

[0035] It should be noted that the mounting frame of the electric control structure can be installed on the ventilation cover. Since the ventilation cover is prone to shaking after being subjected to force, thereby affecting the NVH of the entire vehicle, a shock absorber 3 needs to be provided at the mounting position. The shock absorber 3 provides a buffering force for the mounting legs 2 and the ventilation cover.

[0036] Optionally, the vibration damping member 3 is a flexible member or an elastic member, such as a rubber member or an EVA member.

[0037] Optionally, the vibration damper 3 is a sheet-like structure, which is bonded to the mounting leg 2 and the vehicle body component respectively.

[0038] In some embodiments, see Figure 1 to Figure 2 The fixing member 1 includes a fixing plate 101 and a connecting piece 102. The fixing plate 101 provides support for the electric control structure. The connecting piece 102 is connected to the outer edge of the fixing plate 101. The connecting piece 102 is provided with a first connecting hole 1021 adapted to the second connecting hole on the electric control structure.

[0039] In this embodiment, the fixing plate 101 provides support for the electric control structure, increases the contact area with the electric control structure, and reduces the pressure. The first connection hole 1021 corresponds to the second connection hole, and the connecting piece is inserted into the first connection hole 1021 and the second connection hole to achieve the fixation of the electric control structure and the connecting piece 102. Compared with the bonding or welding method, the solution in this embodiment can not only quickly fix the electric control structure and the connecting piece 102, but also is not affected by temperature, and the connection is firm, while avoiding the problem of damage to the electric control structure due to excessive temperature during welding.

[0040] Optionally, the connecting member includes a bolt and a nut, the bolt is inserted into the first connecting hole 1021 and the second connecting hole, and the nut is screwed with the bolt to fix the electric control structure to the connecting piece 102. The connecting member can also be a clamping member.

[0041] As another specific embodiment of the connecting piece 102, the connecting piece 102 is provided with a first connecting hole 1021, and the first connecting hole 1021 is adapted to the plug-in component on the electric control structure. The plug-in component can be a clamping component or a threaded component. When the plug-in component is a threaded component, it includes a bolt inserted into the first connecting hole 1021 and a nut threadedly connected to the bolt.

[0042] In some embodiments, see Figure 1 to Figure 2 ,and Figure 5 The fixing member 1 further includes a reinforcing block 103 connected to the connecting piece 102 , and the reinforcing block 103 is provided with a reinforcing hole 1031 corresponding to the first connecting hole 1021 .

[0043] The reinforcing block 103 is welded or integrally connected to the connecting piece 102. After the first connecting hole 1021 is aligned with the second connecting hole, the connecting piece 102 is inserted into the first connecting hole 1021, the second connecting hole and the reinforcing hole 1031. This embodiment increases the contact area with the connecting piece 102, avoiding the problem of the connecting piece 102 being easily broken due to excessive pressure after being stressed. The solution in this embodiment does not need to use external nuts during installation, avoiding the problem of finding nuts on site, improving the connection efficiency, and the design of the reinforcing block 103 increases the strength of the periphery of the first connecting hole 1021, reducing the probability of deformation.

[0044] Optionally, the reinforcement hole 1031 is a threaded hole.

[0045] In some embodiments, see Figure 1 to Figure 2 The fixing member 1 is provided with a weight-reducing hole 1011 , and a reinforcing rib 1012 is provided on the periphery of the weight-reducing hole 1011 .

[0046] The weight-reducing hole 1011 can reduce the weight of the fixing part 1, which not only saves materials and reduces production costs, but also helps to achieve lightweighting of the entire vehicle. However, the opening of the weight-reducing hole 1011 will reduce the strength of the fixing part 1, especially the part around the weight-reducing hole 1011 is prone to deformation. Providing a reinforcing rib 1012 around the weight-reducing hole 1011 can improve the strength of the fixing part 1 and reduce the probability of deformation.

[0047] In some embodiments, see Figure 1 The mounting leg 2 includes a connecting portion 201 , a supporting portion 202 and a mounting portion 203 which are sequentially arranged to form a “Z”-shaped structure. The connecting portion 201 is connected to the fixing member 1 , and the mounting positions are distributed on the mounting portion 203 .

[0048] The solution in this embodiment can form a buffer space between the fixing part 1 and the body part, preventing the fixing part 1 from shaking or deforming and causing stress on the body part, thereby improving the NVH performance of the whole vehicle. In addition, the mounting portion 203 fits the body part, increasing the contact area with the body part and improving the stability and firmness of the connection. The "Z"-shaped structure has the advantages of high strength and strong anti-deformation ability, and can provide effective support for the fixing part 1.

[0049] In some embodiments, see Figures 2 to 4 The mounting leg 2 is provided with a mounting hole, the mounting hole forms a mounting position, and the vibration damping member 3 is inserted into the mounting hole.

[0050] The vibration damping member 3 is inserted into the mounting hole, which increases the contact area with the mounting leg 2 and improves the firmness of the connection. In addition, the locking member is inserted into the locking hole and connected to the vehicle body component. The solution in this embodiment can not only provide a buffering force to the mounting leg 2 in the axial direction of the mounting hole, but also provide a buffering force to the locking member in the radial direction of the mounting hole, and the buffering effect is better.

[0051] Optionally, the vibration damping member 3 extends a mounting hole along its own axial direction, and an end of the vibration damping member 3 abuts against a vehicle body component.

[0052] Optionally, the vehicle body is provided with a fastening hole, and the locking member is inserted into the locking hole and the fastening hole; or the locking member is installed on the vehicle body and plugged into the locking hole.

[0053] In some embodiments, see Figure 3 to Figure 4 The outer circumferential surface of the vibration damper 3 is provided with a limiting groove 3011 along the circumferential direction, the vibration damper 3 is inserted into the mounting hole, and the mounting leg 2 is clamped in the limiting groove 3011 to limit the vibration damper 3 in the axial direction.

[0054] The mounting leg 2 is clamped in the limiting groove 3011, limiting the vibration damper 3 in the circumferential direction of the mounting hole, and the connection between the vibration damper 3 and the mounting leg 2 is achieved by relying on the elastic force of the vibration damper 3 itself. There is no need to use the external connecting part 201 or adhesive bonding, and the connection is more convenient.

[0055] In some embodiments, see Figure 3 to Figure 4 The vibration damping member 3 includes a vibration damping ring 301 and a reinforcement sleeve 302. The vibration damping ring 301 is inserted into the mounting hole, and the vibration damping ring 301 is a flexible or elastic component; the reinforcement sleeve 302 includes an insertion portion 3022 and a limiting portion 3021 sleeved outside the insertion portion 3022, the insertion portion 3022 is inserted into the center hole of the vibration damping ring 301, the limiting portion 3021 abuts against the end surface of the vibration damping ring 301, and the insertion portion 3022 is provided with a locking hole, and a locking member is inserted into the locking hole.

[0056] The vibration damping ring 301 is elastic and can buffer the vibration force between the mounting leg 2 and the body component after being subjected to force. The reinforcement sleeve 302 can provide support force for the vibration damping ring 301, increase the overall lowering of the vibration damping component 3, and avoid the problem of excessive deformation of the vibration damping ring 301 causing buffering failure.

[0057] Specifically, the reinforcement sleeve 302 is a rigid component, such as an iron or stainless steel component, and has relatively high strength.

[0058] In some embodiments, see Figure 2 There are multiple mounting legs 2, and the multiple mounting legs 2 are respectively connected to the opposite sides of the fixing member 1 along the left and right directions, wherein the multiple mounting legs 2 connected to one side of the fixing member 1 are respectively provided with first fixing holes 204, and the multiple mounting legs 2 connected to the other side of the fixing member 1 are respectively provided with second fixing holes 205, the axes of the first fixing holes 204 and the second fixing holes 205 are distributed at an angle, and the first fixing hole 204 is a closed through hole, and the second fixing hole 205 is a semi-closed through hole radially connected to the outside, and the vibration damping member 3 is inserted into the first fixing hole 204 or the second fixing hole 205.

[0059] Due to the installation position restriction of the body part, the axes of the first fixing hole 204 and the second fixing hole 205 cannot be parallel. In the solution of this embodiment, when connecting the mounting leg 2 to the body part, the vibration damper 3 can be first inserted into the first fixing hole 204, and the locking member corresponding to the second fixing hole 205 can be fixed to the body. Then the vibration damper 3 is inserted into the locking member, and then the second fixing hole 205 is inserted into the outer periphery of the corresponding vibration damper 3 along the opening direction, and the locking member is inserted into the first fixing hole 204 at the same time. This embodiment can realize multi-angle installation, adapt to different installation positions in the body part, and has a wide range of applications.

The fixing part 1 is connected to the electric control structure, fixed and provides support force to the electric control structure. The mounting leg 2 is fixed to the body part, which provides support force to the fixing part 1 on the one hand, and forms a buffer space between the mounting leg 2 and the body part on the other hand, providing a reserved space for the fixing part 1 to avoid the fixing part 1 from vibrating or deforming when the electric control structure shakes, thereby causing vibration of the body part and causing abnormal noise in the vehicle. A vibration damping part 3 is set at the mounting position of the mounting leg 2. After the fixing part 1 is subjected to force, the vibration force is transmitted to the mounting position through the mounting leg 2. The vibration damping part 3 alleviates the vibration force to avoid deformation or damage of the body part due to the vibration force. At the same time, the vibration damping part 3 can also reduce the noise generated by the vibration force and improve the NVH performance of the whole vehicle.
