Description

Technical Field

[0001] This utility model relates to the field of motor mounting, and in particular to a die-cast aluminum shock absorber for motors. Background Technology

[0002] The motor bracket of a new energy vehicle is a key component to ensure the stable, safe and efficient operation of the drive motor. It is mainly responsible for fixing the drive motor, including bearing various loads during operation, and playing a role in suppressing vibration and noise. The performance of the shock absorber affects the safety, comfort and driving range of new energy vehicles.

[0003] In the prior art, Chinese invention patent application number "CN201710480869.4" discloses a clamping bracket for an electric motor, which fixes the motor by clamping both sides. During the operation of the motor, the motor's interior and housing are subjected to certain loads. For example, under high speed or high torque conditions, the motor itself will vibrate. Clamping only the two sides of the motor cannot fix it well. Therefore, a shock-absorbing bracket with good structural strength, fixing effect and vibration reduction effect is needed under the premise of die casting and lightweight. Utility Model Content

[0004] The purpose of this invention is to provide a die-cast aluminum shock absorber for motors, which has the advantages of high structural strength, good fixing effect and good shock absorption effect.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a die-cast aluminum shock absorber frame for motors, comprising a support body, a conical arc surface limiting hole provided on one side of the center of the support body, and an elastic pad embedded fixing hole provided on the other side of the center of the support body, the conical arc surface limiting hole and the elastic pad embedded fixing hole being concentrically arranged, the two sides of the support body extending outward in the width direction respectively to form fixing ends, each fixing end being provided with a first elastic pad fixing hole and a second elastic pad fixing hole, the upper surface of the fixing end being recessed downward to form a planar mounting groove, the planar mounting groove being provided with a fixing hole for the first elastic pad. The mounting holes are interconnected. The first elastic pad fixing hole and the second elastic pad fixing hole extend along the thickness direction of the fixing end. The first elastic pad fixing hole is set through the conical arc surface limiting hole. The second elastic pad fixing hole is set through the thickness direction of the fixing end. An upper structural reinforcement section is formed between the side of the bracket body and the fixing end. The upper structural reinforcement section is located on both sides of the width direction of the bracket body and above the fixing end. A shock-absorbing groove is provided in the upper structural reinforcement section. The shock-absorbing groove is set through the height direction of the bracket body. The bracket body protrudes outward on one side of the conical arc surface limiting hole to form a structural reinforcement block.

[0006] Preferably, the top of the support body is provided with an arc-shaped surface, the bottom of the support body is provided with a horizontal surface, the two sides of the arc-shaped surface in the width direction are respectively connected to the fixed end, the upper structural reinforcement section is provided at the connection position between the arc-shaped surface and the fixed end, the top of the arc-shaped surface is recessed inward to form a first weight-reducing groove, the first weight-reducing groove is arc-shaped, a stepped groove is provided between the first weight-reducing groove and the shock-absorbing groove, and the stepped groove is recessed inward along the radial direction of the conical arc surface limiting hole.

[0007] By adopting the above technical solutions, the arc-shaped surface can better disperse stress, while the bottom horizontal surface provides a stable and reliable mounting reference surface, which is convenient for assembly with other components. The upper structural reinforcement section strengthens the stress concentration transition area from the arc-shaped main body to the fixed end. The first weight-reducing groove reduces the weight of the bracket, maintains the structural strength of the top arc-shaped surface, and the stepped groove further achieves lightweighting and facilitates demolding.

[0008] Preferably, the outer contour of the structural reinforcing block is flush with the upper structural reinforcing section, the inner contour of the structural reinforcing block is concentric with the conical arc surface limiting hole, the upper and lower contours of the structural reinforcing block are flush, and the structural reinforcing block protrudes from the surface of the support body in the thickness direction.

[0009] By adopting the above technical solution, the structural reinforcement block increases the thickness at this location, thereby further increasing the section modulus of this area and improving its resistance to bending and torsional deformation.

[0010] Preferably, the support body extends outward along the thickness direction on one side of the fixing hole embedded in the elastic pad to form an extension end, and the end of the extension end extends radially outward to form a fixing end face. A die-casting gate is provided on the fixing end face, and the die-casting gate is arranged around the fixing hole embedded in the elastic pad.

[0011] By adopting the above technical solution, the extended end increases the volume of the support body in the conical arc surface limiting hole and the fixed hole embedded in the elastic pad, thereby improving the connection strength. The surrounding die-casting gate allows the molten metal to fill the cavity evenly from the center to the surrounding area, ensuring the density of the core hole area and improving the strength, thereby improving the quality and reliability of the entire support body.

[0012] Preferably, a second weight-reducing groove is provided between the fixed end and the extended end in the thickness direction of the support body, the longitudinal section of the extended end is circular, and a structural reinforcing column is formed between the die-casting gate and the extended end and the second weight-reducing groove, the structural reinforcing column protruding from the bottom of the extended end.

[0013] By adopting the above technical solution, the second weight-reducing groove removes material between the fixed end and the extended end, reducing the weight. The structural reinforcing column, which is the die-casting gate residue formed after the material is removed from the second weight-reducing groove, forms a structural column with reinforcing function, meeting the process requirements of die casting and enhancing the connection strength between the extended end and the main body of the support.

[0014] Preferably, the fixed ends are in the shape of an inverted trapezoid and are respectively arranged on both sides of the width direction of the bracket body. The first elastic pad fixing hole is arranged on the upper part of the fixed end, and the second elastic pad fixing hole is arranged on the lower part of the fixed end.

[0015] By adopting the above technical solution, the shape provides a wider bottom, which enhances the contact stability with the mounting surface, conforms to the principle of triangular stability, improves mechanical performance, and the first elastic pad fixing hole and the second elastic pad fixing hole are distributed vertically to resist torque and vibration in different directions, providing multi-dimensional shock absorption control.

[0016] Preferably, the longitudinal section of the first elastic pad fixing hole is inverted triangular, the longitudinal section of the second elastic pad fixing hole is circular, and the lower sidewall of the first elastic pad fixing hole is provided with a first arc surface, which is concentrically arranged with the second elastic pad fixing hole.

[0017] By adopting the above technical solution, the triangular first elastic pad fixing hole has extremely high stability. This shape can better restrict and fix the elastic pad, prevent it from loosening, and improve the connection strength. At the same time, the first arc surface ensures the structural strength of the second elastic pad fixing hole.

[0018] Preferably, the extended end is provided with a second arc surface on the outside of the second elastic pad fixing hole. The second arc surface is concentric with the second elastic pad fixing hole and is recessed from the side of the second weight reduction groove toward the extended end.

[0019] By adopting the above technical solution, the second arc surface reduces stress concentration and optimizes weight distribution, thereby achieving localized lightweighting of the main body of the support.

[0020] Preferably, the support body has a third weight-reducing groove below the embedded fixing hole of the elastic pad. The third weight-reducing groove is located between adjacent fixing ends and is formed by an upward indentation from the bottom of the support body. The third weight-reducing groove is concentrically arranged with the embedded fixing hole of the elastic pad.

[0021] By adopting the above technical solution, the top of the support body is removed to further reduce weight, while ensuring the strength of the main body sidewall. At the same time, the concentrically set third weight-reducing groove ensures the structural strength around the conical arc surface limiting hole.

[0022] Preferably, the conical arc surface limiting hole is frustoconical in shape, and the embedded fixing hole of the elastic pad includes a first connecting hole, a second connecting hole, and a third connecting hole in sequence. An arc-shaped end is provided between the first connecting hole and the conical arc surface limiting hole. The arc-shaped end protrudes from the side wall of the first connecting hole. The diameter of the first connecting hole is larger than that of the conical arc surface limiting hole and smaller than that of the second connecting hole. There is a stepped transition between the first connecting hole and the second connecting hole, and a sloping transition between the second connecting hole and the third connecting hole. The diameter of the second connecting hole is smaller than that of the third connecting hole.

[0023] By adopting the above technical solution, the conical arc surface limiting hole is truncated cone-shaped. The conical surface fit can achieve precise positioning without gaps and has a good automatic centering effect. The stepped and inclined transition of the fixed hole embedded in the elastic pad improves the structural strength, ensures demolding, and is adapted to the elastic shock-absorbing sleeve with the corresponding contour, forming a multi-level fixing and limiting, making the elastic pad more firmly fixed and not easy to fall out or shift. At the same time, the arc end plays a guiding role and avoids stress concentration, which facilitates the installation of the elastic pad.

[0024] In summary, the conical arc-shaped limiting hole on one side of the center provides high-precision radial positioning and axial limiting functions, effectively preventing vibrations caused by motor loads during operation, ensuring alignment, and reducing wear. The elastic pad with embedded fixing holes on the other side of the center provides a dedicated and stable mounting position for the elastic pad embedded in the conical arc-shaped limiting hole. The concentrically arranged conical arc-shaped limiting holes and elastic pad with embedded fixing holes ensure the alignment of the motor shaft and the mounting reference, resulting in uniform force distribution, smooth operation, and reduced vibration and noise caused by misalignment. The extended fixing ends on both sides increase the mounting contact area with the vehicle suspension, improving the rigidity and stability of the overall connection. The fixing ends have first and second elastic pad fixing holes: installing the elastic pad through two separate fixing points more effectively constrains and absorbs vibrations in different directions, improving the reliability and effect of vibration damping. The flat mounting groove and mounting holes provide a smooth surface... The mounting surface ensures a tight fit with external equipment, preventing stress concentration due to uneven surfaces. Mounting holes allow bolts to enter and tighten into the first elastic pad fixing holes, improving the fixing effect. The extension and through-hole design of the first and second elastic pad fixing holes ensures the elastic pads are fully fixed and limited. The through-hole design facilitates installation and replacement and allows for multi-directional deformation of the elastic pads during compression. It also ensures the structural strength of the bracket body, which has a blind hole structure for the first elastic pad fixing hole. The upper structural reinforcement section adds material to the stress concentration area between the main body and the fixing end, improving the stiffness and structural strength of this area. The damping groove acts as a stress relief groove, preventing crack propagation, improving structural elasticity, enhancing local shock absorption capacity, and achieving lightweighting. The structural reinforcement block increases thickness on one side of the conical arc-shaped limiting hole, strengthening the structural strength at that location and ensuring it can withstand greater vibration loads and maintain structural strength.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0033] Example:

[0034] like Figures 1 to 5 As shown, a die-cast aluminum shock absorber frame for motors includes a support body 1. The top of the support body 1 is provided with an arc-shaped surface 12, and the bottom of the support body 1 is provided with a horizontal surface 14. A conical arc-shaped limiting hole 11 is provided on one side of the center of the support body 1, and an elastic pad embedded fixing hole 2 is provided on the other side of the center of the support body 1. The two sides of the lower width direction of the support body 1 extend outward to form fixing ends 3. The two sides of the arc-shaped surface 12 in the width direction are connected to the fixing ends 3 and integrally formed. The fixing ends 3 play a role in fixing the support body 1 and the suspension.

[0035] like Figures 1 to 5 As shown, in order to fix and dampen the ends of the motor, the main body 1 of the bracket is provided with conical arc surface limiting holes 11 and elastic pad embedded fixing holes 2. The conical arc surface limiting holes 11 and elastic pad embedded fixing holes 2 are concentrically arranged, as shown in the figure. Figure 5 As shown, the specific structure of both is as follows: the conical arc surface limiting hole 11 is truncated cone-shaped, and the elastic pad embedded fixing hole 2 includes a first connecting hole 21, a second connecting hole 22, and a third connecting hole 23 in sequence. An arc-shaped end 24 is provided between the first connecting hole 21 and the conical arc surface limiting hole 11. The arc-shaped end 24 protrudes from the side wall of the first connecting hole 21. The diameter of the first connecting hole 21 is larger than that of the conical arc surface limiting hole, and the diameter of the first connecting hole 21 is smaller than that of the second connecting hole 22. There is a stepped transition between the first connecting hole 21 and the second connecting hole 22, and a sloping transition between the second connecting hole 22 and the third connecting hole 23. The diameter of the second connecting hole 22 is smaller than that of the third connecting hole 23. This allows the elastic pad to be fixed in the embedded fixing hole 2 of the elastic pad, while also being fixed through the conical arc surface limiting hole 11. When the front end of the motor contacts the elastic pad in the conical arc surface limiting hole 11, the vibration of the motor under high torque is reduced.

[0036] like Figure 2 As shown, to fix the elastic pad, each fixing end 3 is provided with a first elastic pad fixing hole 31 and a second elastic pad fixing hole 33. The fixing ends 3 are inverted trapezoidal and are respectively provided on both sides of the width direction of the bracket body 1. The first elastic pad fixing hole 31 is located on the upper part of the fixing end 3, and the second elastic pad fixing hole 33 is located on the lower part of the fixing end 3. The upper surface of the fixing end 3 is recessed downward to form a flat mounting groove 34. The flat mounting groove 34 is provided with a mounting hole 35 that communicates with the first elastic pad fixing hole 31. A bolt passes through the mounting hole 35 and is then connected to the first elastic pad fixing hole 31. The elastic pad has a first elastic pad fixing hole 31 and a second elastic pad fixing hole 33 extending along the thickness direction of the fixing end 3. One end of the first elastic pad fixing hole 31 is a blind hole and the other end is through the conical arc surface limiting hole 11. The second elastic pad fixing hole 33 is through the thickness direction of the fixing end 3. The specific structure is that the longitudinal section of the first elastic pad fixing hole 31 is inverted triangular and the longitudinal section of the second elastic pad fixing hole 33 is circular. The lower side wall of the first elastic pad fixing hole 31 is provided with a first arc surface 32, which is concentrically arranged with the second elastic pad fixing hole 33.

[0037] like Figure 2 and Figure 3As shown, in order to ensure the structural strength at the conical arc surface limiting hole 11, the outer contour of the structural reinforcing block 42 is flush with the upper structural reinforcing section 4, the inner contour of the structural reinforcing block 42 is concentrically set with the conical arc surface limiting hole 11, the upper contour and lower contour of the structural reinforcing block 42 are flush with each other, and the structural reinforcing block 42 protrudes from the surface of the support body 1 in the thickness direction; in order to strengthen the structural strength at the second elastic pad fixing hole 33, the extension end 5 is provided with a second arc surface 55 on the outside of the second elastic pad fixing hole 33, the second arc surface 55 is concentrically set with the second elastic pad fixing hole 33, and the second arc surface 55 is recessed from the side of the second weight reduction groove 53 toward the extension end 5.

[0038] like Figures 1 to 5 As shown, in order to reduce the overall weight of the bracket body 1 and thus reduce the overall weight of the vehicle, a third weight reduction groove 56 is provided below the fixing hole 2 embedded in the elastic pad of the bracket body 1. The third weight reduction groove 56 is located between adjacent fixing ends 3. The third weight reduction groove 56 is formed by the bottom of the bracket body 1 being recessed upward. The third weight reduction groove 56 is concentric with the fixing hole 2 embedded in the elastic pad, and thus the third weight reduction groove 56 is arranged in an upward convex arc shape.

[0039] like Figure 1 As shown, on the side of the top of the support body 1, an upper structural reinforcement section 4 is formed between the side of the support body 1 and the fixed end 3. The upper structural reinforcement section 4 is respectively set on both sides, that is, at the connection position between the arc surface 12 and the fixed end 3. The top of the arc surface 12 is recessed inward to form a first weight reduction groove 13. The first weight reduction groove 13 plays the role of weight reduction. The first weight reduction groove 13 is arc-shaped. A stepped groove 43 is set between the first weight reduction groove 13 and the shock absorption groove 41. The stepped groove 43 is recessed inward along the radial direction of the conical arc surface limiting hole 11. Under the premise of weight reduction, it plays the role of ensuring structural strength. The upper structural reinforcement section 4 is located on both sides of the support body 1 in the width direction and above the fixed end 3. The upper structural reinforcement section 4 is provided with a shock absorption groove 41. The main function of the shock absorption groove 41 is also to ensure the overall structural strength under the premise of reducing weight. At the same time, a large number of cavity structures are set on the side of the motor fixing position to reduce the vibration generated by large torque. The shock absorption groove 41 is set through the support body 1 in the height direction.

[0040] To enhance structural strength, two adjustments were made to the position of the conical arc surface limiting hole 11. First, the size of the embedded fixing hole 2 in the elastic pad on the other side was increased. That is, the bracket body 1 extends outward along the thickness direction on the side of the embedded fixing hole 2 in the elastic pad to form an extension end 5. The extension end 5 serves to lengthen the hole and enhance the structural strength of the covering position. Second, the thickness on this side was increased. That is, the bracket body 1 protrudes outward on the side of the conical arc surface limiting hole 11 to form a structural reinforcing block 42.

[0041] At the same time, such as Figure 2 and Figure 3 As shown, in order to enhance structural strength and ensure the stability of die casting, the end of the extension end 5 extends radially outward to the fixed end 3. A die casting gate 52 is provided on the fixed end 3. The die casting gate 52 is arranged around the fixed hole 2 embedded in the elastic pad. A second weight-reducing groove 53 is provided between the fixed end 3 and the extension end 5 in the thickness direction of the support body 1. The longitudinal section of the extension end 5 is circular. A structural reinforcing column 54 is formed between the die casting gate 52 and the second weight-reducing groove 53. The structural reinforcing column 54 protrudes from the bottom of the extension end 5. The structural strength at the injection gate position formed by die casting is improved, while ensuring the reliability of die casting.
