[0002] With the improvement of people's living standards, the definition of cars has gradually changed. Cars are not only means of transportation. While people enjoy the pleasure of driving cars, they also pursue the sense of technology, luxury and comfort of cars. Installing some lifting components (such as lifting center consoles, lifting TVs, lifting speakers, etc.) in the car interior can well enhance the overall sense of technology and luxury, and this has gradually been implemented in new energy vehicles. For the lifting components in the car interior, the noise generated during their movement will directly affect the comfort experience of passengers, and a considerable part of this noise comes from the running vibration of the driving motor.

[0003] In the prior art, the lifting components are mainly fixed by means of bolt rigid connection and are directly connected to the transmission mechanism. During operation, the vibration of the motor will be directly transmitted to the transmission mechanism, generating relatively large noise. By setting sound-absorbing cotton or sound-proof boxes around the lifting components, the influence of noise on the comfort of passengers is reduced.

[0004] However, the method of wrapping the lifting components with sound-absorbing cotton or sound-proof boxes requires other installation parts and affects the ventilation and heat dissipation of the lifting components.

Detailed implementation manners

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0041] The following further describes in detail an embodiment of a lifting motor and a vehicle for vibration reduction and noise reduction according to the present invention with reference to the accompanying drawings.

[0042] As Figure 1 and Figure 2As shown, on the one hand, the present application provides a lifting motor for vibration reduction and noise reduction, which includes: a mounting frame 1, a belt drive mechanism 3, and a drive motor 4. Among them, the mounting frame 1 is used to connect with the vehicle body; the belt drive mechanism 3 is arranged on the mounting frame 1, and the belt drive mechanism 3 is used to drive the driven member; the drive motor 4 is arranged on the mounting frame 1, and the rotating shaft of the drive motor 4 is connected to the belt drive mechanism 3 through a coupling 5. The drive motor 4 is used to drive the driven member to move through the coupling 5 and the belt drive mechanism 3.

[0043] When using this vibration-reducing and noise-reducing lifting motor, connect the mounting frame 1 to the vehicle body, arrange the belt drive mechanism 3 on the mounting frame 1, and arrange the drive motor 4 on the mounting frame 1. The rotating shaft of the drive motor 4 is connected to the belt drive mechanism 3 through a coupling 5. When the drive motor 4 works, it drives the belt drive mechanism 3 to operate through the coupling 5, and the belt drive mechanism 3 drives the driven member to move. Since the drive motor 4 drives the driven member to move through the coupling 5 and the belt drive mechanism 3, after the secondary noise reduction of the coupling 5 and the belt drive mechanism 3, the noise generated by the operation of the drive motor 4 is reduced, improving the comfort of passengers, and solving the problem in the prior art that it is necessary to set up a connection between the mounting member and the sound-absorbing cotton or sound-proof box, making the structure of the lifting mechanism more complex, and wrapping the sound-absorbing cotton or sound-proof box will affect the service life of the lifting mechanism.

[0044] As Figure 4 and Figure 5 shown, in some alternative embodiments, the coupling 5 includes:

[0045] Two first terminals 51, the two first terminals 51 are arranged opposite to each other. One of the first terminals 51 is connected to the rotating shaft of the drive motor 4, and the other first terminal 51 is connected to the input end of the belt drive mechanism 3;

[0046] A second terminal 52, which is arranged between the two first terminals 51;

[0047] Two silicone buffer pads 53, which are respectively arranged on both sides of the second terminal 52 and are located between the first terminal 51 and the second terminal 52. The silicone buffer pads 53 are used to connect the first terminal 51 and the second terminal 52, so that the first terminal 51, the second terminal 52 and the silicone buffer pads 53 rotate synchronously.

[0048] In this embodiment, the structure of the coupling 5 is specifically described. The coupling 5 includes two first terminals 51, a second terminal 52 and two silicone buffer pads 53. Among them, the two first terminals 51 are arranged oppositely. One of the first terminals 51 is connected to the rotating shaft of the driving motor 4, and the other first terminal 51 is connected to the input end of the belt transmission mechanism 3. The second terminal 52 is arranged between the two first terminals 51. The two silicone buffer pads 53 are respectively arranged on both sides of the second terminal 52 and are located between the first terminal 51 and the second terminal 52. The silicone buffer pad 53 is used to connect the first terminal 51 and the second terminal 52, so that the first terminal 51, the second terminal 52 and the silicone buffer pad 53 rotate synchronously. A silicone buffer pad 53 is arranged between the first terminal 51 and the second terminal 52 of the coupling 5. By means of the silicone buffer pad 53, the collision between the first terminal 51 and the second terminal 52 is reduced, and the vibration reduction and noise reduction effect of the coupling 5 is further improved, thereby improving the comfort of passengers.

[0049] As Figure 5 shown, in some alternative embodiments, a plurality of first connecting columns 511 are provided on one side of each of the two first terminals 51 facing each other, a plurality of second connecting columns 521 are provided on both sides of the second terminal 52, and a plurality of connecting grooves 531 are circumferentially provided on the silicone buffer pad 53. The number of the connecting grooves 531 is the same as the sum of the number of the first connecting columns 511 and the second connecting columns 521 of a single first terminal 51. The first connecting columns 511 and the second connecting columns 521 are used to be inserted into the connecting grooves 531.

[0050] In this embodiment, a plurality of first connecting columns 511 are provided on one side of each of the two first terminals 51 facing each other, a plurality of second connecting columns 521 are provided on both sides of the second terminal 52 facing the two first terminals 51, and a plurality of connecting grooves 531 are circumferentially provided on the silicone buffer pad 53. The number of the connecting grooves 531 is the same as the sum of the number of the first connecting columns 511 and the second connecting columns 521 of a single first terminal 51, so that the first connecting columns 511 and the second connecting columns 521 are inserted into the connecting grooves 531 in a one-to-one correspondence. When one of the first terminals 51 rotates with the rotating shaft of the driving motor 4, a silicone buffer pad 53 is driven to rotate through the first connecting column 511 provided thereon. The silicone buffer pad 53 drives the second terminal 52 to rotate through the connecting groove 531. The second terminal 52 drives the other silicone buffer pad 53 to rotate, and then drives the other first terminal 51 to rotate, transmitting the rotation of the driving motor 4 to the input end of the belt transmission mechanism 3. The structure is reliable and easy to implement.

[0051] In this example, the plurality of first connecting columns 511 are evenly spaced along the circumferential direction of the first terminal 51, the plurality of second connecting columns 521 are evenly spaced along the circumferential direction of the second terminal 52, and the number of the first connecting columns 511 and the second connecting columns 521 on the same side is the same.

[0052] AsFigure 5 As shown, in some alternative embodiments, two first connection posts 511 are provided on one side of the first terminal 51, two second connection posts 521 are provided on both sides of the second terminal 52, four connection slots 531 are provided on the silicone buffer pad 53, and the four connection slots 531 are arranged circumferentially. The first connection posts 511 and the second connection posts 521 are cross-inserted into the connection slots 531.

[0053] In this embodiment, two first connection posts 511 are provided on one side of the first terminal 51, two second connection posts 521 are provided on both sides of the second terminal 52, four connection slots 531 are provided on the silicone buffer pad 53, and the four connection slots 531 are evenly arranged circumferentially. The first connection posts 511 and the second connection posts 521 are cross-inserted into the connection slots 531, so that the connection effect between the first terminal 51, the second terminal 52 and the silicone buffer pad 53 is better, preventing the first terminal 51 from detaching from the silicone buffer pad 53 or the second terminal 52 from detaching from the silicone buffer pad 53 during the operation of the vibration reduction and noise reduction lifting motor, affecting the normal use of the vibration reduction and noise reduction lifting motor, and improving the stability of the vibration reduction and noise reduction lifting motor.

[0054] As Figure 5 shown, in some alternative embodiments, the cross-sections of the first connection posts 511 and the second connection posts 521 are fan-shaped, and the shape of the connection slots 531 is the same as the shapes of the first connection posts 511 and the second connection posts 521.

[0055] In this embodiment, the cross-sections of both the first connection posts 511 and the second connection posts 521 are fan-shaped, and the shape of the connection slots 531 is the same as the shapes of the first connection posts 511 and the second connection posts 521, making the connection between the first connection posts 511 and the second connection posts 521 and the connection slots 531 tighter, preventing the first terminal 51 from detaching from the silicone buffer pad 53 or the second terminal 52 from detaching from the silicone buffer pad 53 during the operation of the vibration reduction and noise reduction lifting motor, affecting the normal use of the vibration reduction and noise reduction lifting motor, and further improving the stability of the vibration reduction and noise reduction lifting motor.

[0056] As Figure 5 shown, in some alternative embodiments, a screw 512 is provided on the first terminal 51, and the screw 512 is used to lock the first terminal 51 and the rotating shaft of the drive motor 4 or the input end of the belt transmission mechanism 3.

[0057] In this embodiment, a screw 512 is provided on the first terminal 51. The screw 512 on one of the first terminals 51 is used to lock the first terminal 51 and the rotating shaft of the driving motor 4, so that the first terminal 51 and the rotating shaft of the driving motor 4 rotate synchronously. The screw 512 on the other first terminal 51 is used to lock the first terminal 51 and the input end of the belt transmission mechanism 3, so that the coupling 5 can effectively transmit the rotation of the rotating shaft of the driving motor 4 to the input end of the belt transmission mechanism 3, making the lifting motor for vibration reduction and noise reduction more stable during use, preventing the separation of the first terminal 51 and the rotating shaft of the driving motor 4, or the separation of the first terminal 51 and the input end of the belt transmission mechanism 3, resulting in the inability to transmit the rotation of the driving motor 4 to the input end of the belt transmission mechanism 3, affecting the normal use of the lifting motor for vibration reduction and noise reduction, and making the driven member unable to be lifted or lowered normally, further improving the stability of the lifting motor for vibration reduction and noise reduction.

[0058] As Figure 1 and Figure 2 shown, in some alternative embodiments, the belt transmission mechanism 3 includes:

[0059] A lead screw assembly 35, which is arranged on the mounting bracket 1 and is rotatably connected to the mounting bracket 1, and the lead screw assembly 35 is used to connect with the driven member;

[0060] A belt pulley rotating shaft 31, which is connected to the first terminal 51;

[0061] Two belt pulleys 32, which are respectively sleeved on the belt pulley rotating shaft 31 and the lead screw assembly 35;

[0062] A transmission belt 33, which is sleeved on the two belt pulleys 32, so that the belt pulley rotating shaft 31 and the lead screw assembly 35 rotate synchronously.

[0063] In this embodiment, the structure of the belt transmission mechanism 3 is specifically described. The belt transmission mechanism 3 includes a lead screw assembly 35, a belt pulley rotating shaft 31, two belt pulleys 32 and a transmission belt 33. Among them, the lead screw assembly 35 is arranged on the mounting bracket 1 and is rotatably connected to the mounting bracket 1. The lead screw assembly 35 is used to connect with the driven member. The belt pulley rotating shaft 31 is connected to the first terminal 51. The two belt pulleys 32 are respectively sleeved on the belt pulley rotating shaft 31 and the lead screw assembly 35. The transmission belt 33 is sleeved on the two belt pulleys 32, so that the belt pulley rotating shaft 31 and the lead screw assembly 35 rotate synchronously. The kinetic energy of the driving motor 4 is transmitted to the lead screw assembly 35 through the two belt pulleys 32 and the transmission belt 33. Compared with the traditional direct connection of the rotating shaft of the driving motor 4 and the lead screw assembly 35, the running vibration of the driving motor 4 can be weakened and absorbed through the transmission belt 33, improving the stability of the operation of the lead screw assembly 35 and reducing the noise of the operation of the driving motor 4, thereby improving the comfort of the passengers.

[0064] As Figure 2As shown, in some alternative embodiments, the mounting bracket 1 is provided with a mounting hole through which the pulley rotating shaft 31 passes. A silica gel sleeve 34 is sleeved on the pulley rotating shaft 31, and the silica gel sleeve 34 is located between the pulley rotating shaft 31 and the mounting hole.

[0065] In this embodiment, the mounting bracket 1 is provided with a mounting hole through which the pulley rotating shaft 31 passes. A silica gel sleeve 34 is sleeved on the pulley rotating shaft 31, and the silica gel sleeve 34 is located between the pulley rotating shaft 31 and the mounting hole, avoiding the impact abnormal noise caused by the collision between the pulley rotating shaft 31 and the hole wall of the mounting hole of the mounting bracket 1 during the rotation of the pulley rotating shaft 31 when the vibration-damping and noise-reducing lifting motor operates, reducing the noise during the operation of the vibration-damping and noise-reducing lifting motor, and further improving the comfort of passengers.

[0066] As Figures 1 - 3 shown, in some alternative embodiments, the mounting bracket 1 includes:

[0067] A motor mounting bracket 11, which is connected to the driving motor 4, and a mounting hole is provided on the lower side of the motor mounting bracket 11;

[0068] A transmission member mounting bracket 12, which is arranged below the motor mounting bracket 11, and the transmission member mounting bracket 12 is rotatably connected to the pulley rotating shaft 31;

[0069] A mounting plate 13, which is connected to the motor mounting bracket 11 and is used for connecting to the vehicle body.

[0070] In this embodiment, the structure of the mounting bracket 1 is specifically described. The mounting bracket 1 includes a motor mounting bracket 11, a transmission member mounting bracket 12, and a mounting plate 13. Among them, the motor mounting bracket 11 is connected to the driving motor 4, a mounting hole is provided on the lower side of the motor mounting bracket 11, the transmission member mounting bracket 12 is arranged below the motor mounting bracket 11, the transmission member mounting bracket 12 is rotatably connected to the pulley rotating shaft 31, the mounting plate 13 is connected to the motor mounting bracket 11 and is used for connecting to the vehicle body. A first accommodation space is provided inside the motor mounting bracket 11 for placing the coupling 5, and a second accommodation space between the motor mounting bracket 11 and the transmission member mounting bracket 12 is used for placing the pulley 32 at the input end of the belt transmission mechanism 3. The structure is simple, the space distribution is reasonable, and the space utilization rate is high.

[0071] In this example, the mounting plate 13 is connected to the motor mounting bracket 11 through a connecting member 14, making the connection effect between the mounting plate 13 and the motor mounting bracket 11 better, improving the stability of the mounting bracket 1, and further improving the structural stability of the vibration-damping and noise-reducing lifting motor, making the vibration-damping and noise-reducing lifting motor operate more safely.

[0072] In this example, the drive motor 4 is connected to the motor mounting bracket 11 by four mounting bolts 6. A rubber vibration damping sleeve 2 is sleeved on each mounting bolt 6. Adding the rubber vibration damping sleeve 2 at the position of the mounting bolt 6 can convert the traditional rigid connection into a flexible connection with a certain displacement activity, reducing the collision abnormal noise between the drive motor 4 and the motor mounting bracket 11 during the operation of the lifting motor for vibration reduction and noise reduction, thereby improving the comfort of passengers. The rubber vibration damping sleeve 2 is a spherical sleeve.

[0073] As Figure 1 and Figure 2 shown, on the other hand, the present application also provides a vehicle, which includes the above-mentioned lifting motor for vibration reduction and noise reduction.

[0074] When using the lifting motor for vibration reduction and noise reduction, the mounting bracket 1 is connected to the vehicle body. The belt drive mechanism 3 is arranged on the mounting bracket 1, and the drive motor 4 is arranged on the mounting bracket 1. The rotating shaft of the drive motor 4 is connected to the belt drive mechanism 3 through a coupling 5. When the drive motor 4 works, the belt drive mechanism 3 is driven to operate through the coupling 5, and the belt drive mechanism 3 drives the driven part to move. Since the drive motor 4 drives the driven part to move through the coupling 5 and the belt drive mechanism 3, after the secondary noise reduction of the coupling 5 and the belt drive mechanism 3, the noise generated during the operation of the drive motor 4 is reduced, and the comfort of passengers is improved, solving the problem in the prior art that it is necessary to set up a connection between the mounting part and the sound-absorbing cotton or the sound-proof box, making the structure of the lifting mechanism more complex, and wrapping the sound-absorbing cotton or the sound-proof box will affect the service life of the lifting mechanism.

[0075] In summary, this solution does not require additional sound-absorbing cotton or sound-proof box around the drive motor 4, reducing the part cost. Moreover, the drive motor 4 is connected to the motor mounting bracket 11 by four mounting bolts 6, and a rubber vibration damping sleeve 2 is sleeved on each mounting bolt 6. While reducing vibration and noise, it can effectively protect the drive motor 4 and extend the service life of the lifting motor for vibration reduction and noise reduction. Compared with the traditional motor mounting and layout structure, this structural solution can reduce the noise by 25 - 35 dB.
