Description

Technical Field

[0001] This utility model relates to the field of starter technology, and in particular to a silent starter for automobiles. Background Technology

[0002] With the continuous development of the automotive industry, the requirements for vehicle comfort, environmental friendliness, and intelligence are gradually increasing. Traditional internal combustion engine starting systems generate significant noise during startup, becoming a key factor affecting vehicle comfort and driving experience. Furthermore, with the rise of electrification and hybrid technologies, the demands on vehicle starting systems have changed, requiring efficient starting while minimizing noise and vibration, typically necessitating noise reduction treatments for the vehicle's starter motor.

[0003] Traditional automotive starters typically use an electric motor to drive the engine, which then engages with the engine flywheel via gears to start the engine. During this process, the impact of gear engagement and the noise from the electric motor often result in noticeable mechanical noise and vibration. Furthermore, the instantaneous load changes during engine startup can also cause unnecessary shocks to the vehicle's electrical system, generating noise. Therefore, a silent starter motor for automobiles has been proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The purpose of this invention is to provide a silent starter motor for automobiles, thereby solving the problem of noise reduction for automobile starter motors mentioned in the background art.

[0008] As a further embodiment of this invention, the surface of the starter housing is provided with several connection holes, and the heat-conducting pillars are inserted into the connection holes. The heat-conducting pillars absorb heat from inside the starter housing and transfer the heat to the surface of the heat sink for dissipation.

[0009] As a further embodiment of this utility model, the heat-conducting column is located inside the starter housing, and four connecting parts are fixedly connected to the bottom of the starter housing. The connecting parts enable the quick assembly and disassembly of the bottom buffer mechanism.

[0010] As a further embodiment of this utility model, the connector has a threaded hole inside, and a buffer mechanism is threadedly connected inside the threaded hole. The buffer mechanism buffers the starter housing and prevents the starter housing from vibrating and generating noise.

[0011] As a further embodiment of this utility model, the buffer mechanism includes a silicone pad threaded into the threaded hole, and a plurality of anti-slip blocks are installed on the bottom of the silicone pad. The anti-slip blocks prevent the silicone pad from slipping.

[0014] (III) Beneficial Effects

[0015] This utility model provides a silent starter motor for automobiles, which has the following beneficial effects:

[0016] 1. This car silent starter uses a noise reduction mechanism. When the equipment is in use, the starter housing has a cavity inside, and several horizontal and vertical connecting plates are installed inside the cavity. The horizontal and vertical connecting plates are cross-connected to form a honeycomb shape. Because the honeycomb structure itself has good sound absorption characteristics, sound waves can be reflected and refracted multiple times when passing through the cavity, thereby effectively converting the energy of the sound waves into heat energy and reducing the propagation of sound waves. This achieves the noise reduction effect, improves the sound insulation performance of the equipment, and avoids excessive noise from the equipment, thus preventing noise pollution to the surrounding environment.

[0017] 2. This car uses a silent starter motor. Through the design of the heat dissipation mechanism, a large amount of heat is generated inside the device when it is started. Therefore, several heat dissipation strips are installed on the surface of the starter motor housing. Multiple heat conduction columns are set at the bottom of the heat dissipation strips. The heat conduction columns are located inside the starter motor housing and transfer heat to the surface of the heat dissipation strips for heat exchange. In conjunction with two low-noise cooling fans on one side of the connecting block, the surface of the heat dissipation strips is quickly cooled, thereby improving the heat dissipation efficiency of the device and preventing the internal temperature of the starter motor housing from becoming too high, which would affect the normal use of the device.

[0024] Please see Figures 1 to 4This utility model provides a technical solution: a silent starter motor for automobiles, including a starter motor housing 1, with a cavity inside the starter motor housing 1. A noise reduction mechanism 2 is fixedly connected inside the cavity. The noise reduction mechanism 2 improves the sound insulation performance of the device, preventing excessive noise from causing noise pollution to the surrounding environment. Several heat dissipation mechanisms 3 are fixedly connected to the surface of the starter motor housing 1, thereby improving the heat dissipation efficiency of the device and preventing the internal temperature of the starter motor housing 1 from becoming too high, which would affect the normal use of the device. A connecting block 4 is fixedly connected to one edge of the top surface of the starter motor housing 1, and two low-noise cooling fans 5 are installed on the surface of the connecting block 4. The noise reduction mechanism 2 includes several longitudinal connecting plates 201 fixedly connected inside the cavity. Several transverse connecting plates 202 are fixedly connected to the surface of the longitudinal connecting plates 201. The longitudinal connecting plates 201 and the transverse connecting plates 202 are cross-connected to form a honeycomb structure. The heat dissipation mechanism 3 includes several heat dissipation strips 301 fixedly connected to the surface of the starter motor housing 1. Several heat conduction columns 302 are fixedly connected to the bottom of the heat dissipation strips 301.

[0025] The starter housing 1 has several connection holes on its surface. Heat-conducting pillars 302 are inserted into these connection holes. The heat-conducting pillars 302 absorb heat from inside the starter housing 1 and transfer it to the surface of the heat sink 301 for heat dissipation.

[0026] The heat-conducting column 302 is located inside the starter housing 1. Four connectors 6 are fixedly connected to the bottom of the starter housing 1. The connectors 6 enable the quick assembly and disassembly of the bottom buffer mechanism 7.

[0027] The connector 6 has a threaded hole inside, and a buffer mechanism 7 is threaded inside the threaded hole. The buffer mechanism 7 buffers the starter housing 1 and prevents the starter housing 1 from vibrating and generating noise.

[0028] The buffer mechanism 7 includes a silicone pad 701 threaded into the threaded hole. Several anti-slip blocks 702 are installed on the bottom of the silicone pad 701. The anti-slip blocks 702 prevent the silicone pad 701 from slipping.

[0029] The top of the silicone pad 701 has four threaded holes, and the internal threads of the threaded holes are connected to positioning bolts 8. The positioning bolts 8 enable quick assembly and disassembly of the bottom silicone pad 701.

[0031] In this invention, the working steps of the device are as follows:

[0032] First step: When using the equipment, the starter housing 1 has a cavity inside, and several transverse connecting plates 202 and longitudinal connecting plates 201 are installed inside the cavity. The transverse connecting plates 202 and longitudinal connecting plates 201 are cross-connected to form a honeycomb shape. Since the honeycomb structure itself has good sound absorption characteristics, the sound waves can be reflected and refracted multiple times in the cavity when passing through it, thereby effectively converting the energy of the sound waves into heat energy and reducing the propagation of the sound waves, thus achieving noise reduction.

[0033] The second step: When the device is started, a lot of heat will be generated inside. Therefore, several heat dissipation strips 301 are installed on the surface of the starter housing 1. Multiple heat conduction columns 302 are set at the bottom of the heat dissipation strips 301. The heat conduction columns 302 are located inside the starter housing 1 and transfer heat to the surface of the heat dissipation strips 301 for heat exchange. Together with two low-noise cooling fans 5 on the connecting block 4 on one side, the surface of the heat dissipation strips 301 is quickly cooled.
