Description

Technical Field

[0001] The utility model relates to the technical field of micromotors, in particular to a micromotors for adjusting the inclination angle of automobile seats. Background Art

[0002] A micromotor is a small-sized, small-capacity motor with an output power generally below a few hundred watts. It is also a motor with special applications, performance and environmental conditions. Micromotors are often used in control systems or transmission mechanical loads. In the process of adjusting the angle of a car seat, a micromotor is used to drive the backrest to adjust the inclination to suit different lying postures.

[0003] According to the automatic angle-adjusting car seat micromotor disclosed in Chinese patent publication number CN219214785U, the micromotor can adjust the angle of the motor body and can play a certain sound insulation role through the internal high-density sound insulation cotton, thereby improving the comfort and experience during the adjustment process. However, in actual use, the micromotor is only a device fixed at a certain location to play a driving role. Therefore, when adjusting the seat back, the patent's method of automatically adjusting the angle of the motor body is relatively useless in actual application. At the same time, since the backrest is in a locked state after the adjustment is completed, the micromotor does not need to work continuously, resulting in the actual effect of the patent that only uses sound insulation cotton to play a sound insulation role. There is room for improvement. Based on this, the present application provides a micromotor for adjusting the inclination of a car seat to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 The utility model provides a technical solution: a micromotor for adjusting the inclination angle of a car seat, comprising a base 1, two fixing frames 2 are fixedly installed on the top of the base 1, and a micromotor mechanism 300 is fixedly installed between the tops of the two fixing frames 2; the micromotor mechanism 300 comprises a shell 301, a transmission component and a sound insulation component; the transmission component is arranged on the inner side of the shell 301 and is used to play a transmission role, and the sound insulation component is arranged on the outer side of the transmission component and is used to play a sound insulation effect; through the coordinated use between the fixing frame 2 on the top of the base 1 and the micromotor mechanism 300, the noise during the working process can be further reduced, so that the micromotor can be effectively improved in a practical direction, and the internal noise is difficult to be transmitted through the internal and external two-layer sound insulation and noise reduction structure. At the same time, by auxiliary support for the output structure, the transmission work can be carried out more smoothly, thereby reducing the noise during the transmission process, so that the noise of the car seat during the adjustment process can be effectively controlled, so that the occupant can perform the adjustment operation comfortably and steadily.

[0026] The sound insulation component in this embodiment is a structure used to further improve the sound insulation effect during the operation of the micromotor.

[0027] like Figure 1 , Figure 3 and Figure 4As shown, the sound insulation component includes a high-density sound insulation pad 3031 bonded to the inner side of the outer shell 301, a mounting groove 3032 opened on the left side of the outer shell 301, a sealing ring 3033 filled in the inner side of the mounting groove 3032, a sound insulation sleeve 3034 sleeved on the outer side of the outer shell 301, and a plurality of circular holes 3035 opened on the outer side of the sound insulation sleeve 3034.

[0028] It should be noted that the left side of the outer shell 301 is open, and a through hole for the output shaft 3023 to pass through is provided on the left side of the high-density sound insulation pad 3031, so that the output shaft 3023 can work normally, and the inner side of the high-density sound insulation pad 3031 has a plurality of protrusions, so that the high-density sound insulation pad 3031 can effectively absorb noise through the protrusions, wherein the high-density sound insulation pad 3031 can be a polyethylene pad.

[0029] In addition, the sound insulation sleeve 3034 is a polyurethane annular sleeve, and a plurality of circular holes 3035 are evenly distributed on the outside of the sound insulation sleeve 3034, so that the sound insulation sleeve 3034 can effectively absorb and offset the transmitted noise, and the gaps between the holes can be used to enhance the noise absorption effect under the action of the circular holes 3035.

[0030] In this embodiment, the transmission assembly is a structure used to allow the micromotor to perform transmission work normally.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, the transmission assembly includes a fixed block 3021 fixed to the inner bottom wall of the shell 301, a power component 3022 fixedly installed on the top of the fixed block 3021, an output shaft 3023 movably installed on the output end of the power component 3022, a support block 3024 fixed to the inner side of the shell 301, a cover plate 3025 detachably connected to the left side of the shell 301, and four heat dissipation holes 3026 opened on the left side of the cover plate 3025 and evenly distributed.

[0032] It should be noted that the power component 3022 is a structure used for the motor to provide output power. Specifically, a rotating magnetic field is generated by an energized coil (that is, a stator winding) and acts on a rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electric power rotation torque, so that the output end rotates. It is an existing technical structure. The left end of the output shaft 3023 passes through the right side of the support block 3024, and the outer side of the output shaft 3023 is rotatably connected to the left side of the support block 3024 through a bearing, so that the support block 3024 can support the output shaft 3023 and enable it to rotate more smoothly.

[0033] In addition, an output hole for the output shaft 3023 to pass through is opened on the left side of the cover 3025, so that the output shaft 3023 can extend to the outside through the output hole, and a dustproof net is fixedly installed on the inner side of the heat dissipation hole 3026 to play a dustproof role. The sealing ring 3033 is a rubber ring, and the left side of the sealing ring 3033 abuts against the right side of the cover 3025, so that the sealing ring 3033 can play a role of elastic abutment, so that the connection between the cover 3025 and the left side of the outer shell 301 can be tightly connected.

[0034] The working principle of the above embodiment is:

[0035] When working, start the power component 3022 to make the output shaft 3023 rotate and output power. During the rotation process, the output shaft 3023 can be transmitted more smoothly and smoothly under the support of the support block 3024. The high-density sound insulation pad 3031 can play a preliminary isolation and absorption role on the noise inside the shell 301. The sound insulation sleeve 3034 and the circular hole 3035 can perform secondary absorption on the noise transmitted to the outside world, thereby playing a good role in sound insulation and noise reduction, so that the transmission work can be carried out comfortably.

[0036] Compared with the prior art, the micromotor for adjusting the inclination angle of the automobile seat can further reduce the noise during the working process through the coordinated use of the fixing frame 2 on the top of the base 1 and the micromotor mechanism 300, so that the micromotor can be effectively improved in the direction of practicality. The internal noise is difficult to be transmitted through the inner and outer layers of the sound insulation and noise reduction structure. At the same time, the transmission work can be carried out more smoothly by auxiliary support for the output structure, thereby reducing the noise during the transmission process, so that the noise of the automobile seat during the adjustment process can be effectively controlled, allowing the occupants to perform the adjustment operation comfortably and steadily, solving the problem that the noise blocking effect of the existing automobile seat micromotor has a certain room for improvement.
