[0005] A motor mounting and vibration damping device includes a motor, mounting bases fixed at the front and rear ends of the motor, and a rubber pad fixed between the mounting bases and the motor. The rubber pad prevents the motor from directly contacting the mounting bases. Multiple through holes are provided on the cover plates at the front and rear ends of the motor. At least two positioning posts that match the through holes are fixed on the side of the rubber pad facing the motor. The positioning posts are engaged in the through holes to prevent the motor from rotating radially.

[0013] The innovative points of this utility model are as follows:

[0014] 1. Matching design between the rubber pad and the mounting slot of the fixing seat:

[0015] The mounting base has a mounting groove on the side facing the motor that matches the shape of the rubber pad. The rubber pad is precisely positioned by snapping into the mounting groove. The top of the mounting groove is open for easy assembly and disassembly.

[0016] Technical benefits: Simplifies installation steps and improves assembly accuracy; reduces displacement of rubber pads during operation through tight fit, enhancing shock absorption stability;

[0019] Technical effects: Effectively limits the radial rotation of the motor, preventing displacement deviation caused by vibration; improves the connection rigidity between the motor and the fixed structure, while retaining the elastic deformation space required for shock absorption;

[0020] 3. Strengthen the supporting ribs to improve the strength of the fixing seat:

[0021] The mounting base has multiple reinforcing ribs on the side away from the motor to optimize the mechanical distribution;

[0022] Technical effects: Significantly enhances the bending and torsional resistance of the mounting base, preventing fatigue deformation caused by long-term vibration; extends the service life of the mounting structure;

[0037] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0038] like Figure 1-4 As shown, a motor fixing and shock absorption device includes a motor 1, a fixing seat 2 fixed at both ends of the motor 1, and a rubber pad 3 fixed between the fixing seat 2 and the motor 1. The rubber pad 3 isolates the motor 1 from direct contact with the fixing seat 2. The cover plates 4 at both ends of the motor 1 are provided with multiple through holes 5. At least two positioning posts 6 that match the through holes 5 are fixed on the side of the rubber pad 3 facing the motor 1. The positioning posts 6 are inserted into the through holes 5 to prevent the motor 1 from rotating radially.

[0039] The hardness of the rubber pad 3 is Shore A 65-75.

[0040] The mounting base 2 has a mounting groove 7 on the side facing the motor 1. The mounting groove 7 matches the shape of the rubber pad 3. The rubber pad 3 is inserted into the mounting groove 7. The top of the mounting groove 7 is designed to be open.

[0041] The outer side of the cover plate 4 is fixed with an outwardly protruding positioning platform 8 at the shaft center of the motor 1. The center of the positioning platform 8 is provided with a shaft hole 9 that matches the motor shaft of the motor 1.

[0042] The rubber pad 3 has a positioning hole 10 that matches the positioning platform 8, and the positioning platform 8 is inserted into the positioning hole 10.

[0043] The mounting base 2 has a U-shaped hole 11 that passes through the mounting base 2 in the axial direction of the motor 1, and the top of the U-shaped hole 11 is designed to be open.

[0044] The mounting base 2 has multiple reinforcing support ribs 12 fixed on the side away from the motor 1.

[0045] The rubber pad 3 is made of oil-resistant and high-temperature-resistant synthetic rubber.

[0046] This utility model achieves efficient vibration reduction, noise reduction, and stable operation through the following core design:

[0047] 1. The elastic deformation of the rubber pad absorbs vibration energy:

[0048] The rubber pad 3 is clamped between the motor 1 and the fixed base 2, isolating them from direct contact. The vibration generated by the motor 1 during operation is converted into heat energy through the elastic deformation of the rubber pad 3, which significantly reduces the vibration amplitude transmitted to the fixed base 2. The hardness of the rubber pad 3 (Shore A 65-75 degrees) has been optimized to ensure sufficient elasticity to absorb high-frequency vibration and to provide rigid support to prevent the motor from sinking or shifting.

[0049] 2. Anti-rotation mechanism between the positioning post and the through hole in the cover plate:

[0050] Two positioning posts 6 are provided on the side of the rubber pad 3 facing the motor 1, which are precisely engaged with the through holes 5 on the motor cover plate 4. The design of the positioning posts with a diameter of 1.3mm and a height of 1mm can limit the radial rotational displacement of the motor 1 caused by vibration, and avoid excessively restricting the elastic deformation space of the rubber pad, thus ensuring a balance between shock absorption effect and dynamic stability.

[0051] 3. Axial positioning of the positioning table and positioning holes:

[0052] The outer side of the cover plate 4 is provided with a positioning platform 8 with a shaft hole 9. The rubber pad 3 has a positioning hole 10 at the corresponding position. The positioning platform 8 is inserted into the positioning hole 10 to achieve precise alignment of the shaft of the motor 1, avoid axial offset, and allow the rubber pad 3 to deform freely in the radial direction to absorb vibration.

[0053] 4. Strengthen the fatigue resistance design of the supporting ribs:

[0054] The fixed base 2 has multiple reinforcing support ribs 12 on the side away from the motor 1, which optimizes the mechanical distribution and improves the bending and torsional resistance. This design disperses the stress generated by long-term vibration, prevents fatigue deformation of the fixed base, and significantly extends its service life.

[0055] 5. Adaptability to high-temperature and oil-resistant materials:

[0056] Rubber pad 3 is made of oil-resistant and high-temperature resistant synthetic rubber. It can maintain its elasticity and durability in high-temperature or oily environments, avoid aging and cracking, and ensure the reliable operation of the device in complex working conditions such as automotive electrical appliances and medical instruments.

[0057] Workflow summary:

[0058] After the motor starts, the vibration energy is absorbed by the elastic deformation of the rubber pad, reducing the vibration amplitude transmitted to the fixed structure (noise reduction of more than 30%); the positioning column and through hole cooperate to suppress radial rotation, the mounting groove and U-shaped hole ensure assembly accuracy, and the support ribs enhance the fatigue resistance of the structure, ultimately achieving the goal of stable vibration reduction and extending the service life of the equipment.

[0059] Finally, it should be noted that the above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
