Description

Technical Field

[0001] This utility model relates to the field of starter motor technology, and in particular to a starter motor that can improve assembly sealing. Background Technology

[0002] As a core drive component during the startup phase of power equipment, the starter motor is widely used in passenger cars, commercial vehicles, construction machinery, ships, and agricultural machinery, providing the necessary torque for the initial operation of power devices such as internal combustion engines. With the development of various power equipment towards multiple specifications and operating conditions, scenarios such as low-temperature operation and high-frequency start-stop operation are becoming increasingly common, while the overall equipment is moving towards integrated design.

[0003] Dust and moisture from the outside of the existing starter motor can enter the motor and contaminate the components. At the same time, the heat generated during long-term and repeated operation can easily damage the core components.

[0004] To address this, a starting motor that can improve assembly sealing is proposed. Utility Model Content

[0005] In view of this, the present invention aims to provide a starting motor that can improve assembly sealing, so as to solve or alleviate the technical problems existing in the prior art, or at least provide a beneficial alternative.

[0006] The technical solution of this utility model embodiment is implemented as follows: A starter motor that can improve assembly sealing includes a main body and a sealing mechanism disposed on the top of the main body. The main body includes: a starter motor body, a base plate disposed at the bottom of the starter motor body, and a snap-fit ​​groove disposed on the top of the base plate; the sealing mechanism includes a snap-fit ​​ring disposed inside the snap-fit ​​groove, a sealing cover disposed on the top of the snap-fit ​​ring, a sealing ring disposed on one side of the sealing cover, a rubber ring disposed at the bottom of the snap-fit ​​ring, a heat sink disposed on one side of the sealing cover, a copper plate disposed inside one side of the heat sink, a cold-conducting plate disposed on one side of the copper plate, a cooling chip disposed on one side of the cold-conducting plate, a heat sink disposed on one side of the cooling chip, a heat sink column disposed on one side of the heat sink, a low-noise fan disposed on one side of the heat sink, and a filter plate disposed at one end of the heat sink.

[0007] In some embodiments, a mounting box is provided on one side of the sealing cover, a mounting plate is provided on one side inside the mounting box, and a cooling fan is provided on one side of the mounting plate.

[0008] In some embodiments, a dustproof net is provided on one side of the interior of the mounting box, and an air inlet box is provided on one side of the mounting box.

[0009] In some embodiments, an air inlet is provided at the bottom of the air inlet box, an air inlet groove is provided inside the air inlet box, and an air outlet is provided on the other side of the sealing cover.

[0010] In some embodiments, a heat-absorbing plate is provided on one side of the top inside the sealing cover, and the heat-absorbing plate has openings inside.

[0011] The present invention has the following advantages due to the adoption of the above technical solution: 1. A starter motor with improved assembly sealing performance. During assembly, the snap-fit ​​ring precisely matches the snap-fit ​​groove of the base plate, and the rubber ring at the bottom of the snap-fit ​​ring strengthens the bottom seal. At the same time, the sealing ring on one side of the sealing cover further fills the gap between the sealing cover and the starter motor body, forming a multi-dimensional sealing structure. This effectively isolates external dust, moisture, and other impurities from entering the starter motor body, preventing contamination of core components. When the motor is running, the heat generated by the starter motor body is first quickly absorbed by the copper plate in the heat sink, and then transferred to the cooling chip for active cooling via the cold conduction plate. The cooled heat is then conducted to the heat sink, and the heat dissipation area is expanded through the heat dissipation columns. A low-noise fan accelerates air circulation to efficiently remove heat, and the filter plate at one end of the heat sink can filter air impurities entering the heat sink, preventing dust from adhering and affecting the performance of the heat dissipation components. The entire process achieves efficient heat dissipation to ensure the stability of motor operation, and the low-noise fan reduces operating noise. At the same time, the sealing and heat dissipation systems work together to significantly improve the service life and long-term operational reliability of the motor.

[0012] 2. A starter motor that can improve the sealing performance of the assembly, wherein when in use, the cooling fan inside the mounting box draws in external air through the air inlet slot at the bottom of the air inlet box and cools the inside of the sealing cover by blowing cool air, while hot air is discharged through the air outlet on the other side of the mounting box for overall heat dissipation.

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] Example 1:

[0021] like Figure 1-6As shown, a starter motor with improved assembly sealing includes a main body 100 and a sealing mechanism 200 snapped and fixed to the top of the main body 100. The main body 100 includes: a starter motor body 101, a base plate 102 mounted on the bottom of the starter motor body 101, and a snap-fit ​​groove 103 formed on the top of the base plate 102; the sealing mechanism 200 includes a snap-fit ​​ring 203 snapped and fixed inside the snap-fit ​​groove 103, a sealing cover 201 mounted on the top of the snap-fit ​​ring 203, a sealing ring 202 mounted on one side of the sealing cover 201, and a rubber ring 204 bonded to the bottom of the snap-fit ​​ring 203. The snap-fit ​​ring 203 is precisely fitted with the snap-fit ​​groove 103 of the base plate 102, and the rubber ring 204 at the bottom of the snap-fit ​​ring 203 strengthens the bottom seal. At the same time, the sealing ring 202 on one side of the sealing cover 201 further fills the gap between the sealing cover 201 and the starter motor body 101. The heat sink 205 on one side of the heat sink 201, the copper plate 206 installed inside the heat sink 205, the cooling plate 207 attached to the side of the copper plate 206, the cooling chip 208 attached to the side of the cooling plate 207, the heat sink 209 attached to the side of the cooling chip 208, the heat sink column 210 integrally formed on the side of the heat sink 209, the low-noise fan 211 installed on the side of the heat sink 209, and the filter plate 212 installed at one end of the heat sink 205. When the motor runs, the heat generated by the starting motor body 101 is first quickly absorbed by the copper plate 206 inside the heat sink 205, and then transferred to the cooling chip 208 for active cooling through the cooling plate 207. The cooled heat is then conducted to the heat sink 209, and the heat dissipation area is expanded through the heat sink column 210. The low-noise fan 211 accelerates the air circulation to efficiently remove heat, and the filter plate 212 at one end of the heat sink 205 can filter air impurities entering the heat sink 205.

[0022] In this embodiment, a mounting box 213 is installed on one side of the sealing cover 201. A mounting plate 214 is installed on one side inside the mounting box 213. A cooling fan 215 is installed on one side of the mounting plate 214. A dustproof net 216 is installed on one side inside the mounting box 213. An air inlet box 217 is installed on one side of the mounting box 213. An air inlet 218 is opened at the bottom of the air inlet box 217. An air inlet slot is opened inside the air inlet box 217. An air outlet is opened on the other side of the sealing cover 201. The cooling fan 215 inside the mounting box 213 draws in external air through the air inlet slot at the bottom of the air inlet box 217 and sends it into the sealing cover 201 to dissipate cold air. Hot air is discharged through the air outlet on the other side of the mounting box 213 to dissipate overall heat dissipation.

[0023] In this embodiment, a heat-absorbing plate 219 is installed on one side of the top inside the sealing cover 201. The heat-absorbing plate 219 has an opening 220 inside. The heat-absorbing plate 219 at the top inside the sealing cover 201 can quickly absorb the heat generated by the starting motor body 101, and the opening 220 on the heat-absorbing plate 219 can accelerate the flow of heat in the sealing cover 201 and avoid local heat accumulation.

[0024] In this embodiment: During assembly, the snap ring 203 is precisely fitted with the snap groove 103 of the base plate 102, and the rubber ring 204 at the bottom of the snap ring 203 strengthens the bottom seal. At the same time, the sealing ring 202 on one side of the sealing cover 201 further fills the gap between the sealing cover 201 and the starter motor body 101, forming a multi-dimensional sealing structure. This effectively isolates external dust, moisture, and other impurities from entering the starter motor body 101, preventing contamination of core components. When the motor is running, the heat generated by the starter motor body 101 is first quickly absorbed by the copper plate 206 inside the heat sink 205, and then conducted away. The cold plate 207 transfers heat to the cooling chip 208 for active cooling. The cooled heat is then conducted to the heat sink 209, and the heat dissipation area is expanded by the heat sink column 210. The low-noise fan 211 accelerates air circulation to efficiently remove heat. The filter plate 212 at one end of the heat sink 205 can filter air impurities entering the heat sink 205 to prevent dust from adhering and affecting the performance of the heat dissipation components. The whole process not only achieves efficient heat dissipation to ensure the stability of motor operation, but also reduces operating noise through the low-noise fan 211. At the same time, the sealing and heat dissipation system work together to greatly improve the service life and long-term reliability of the motor.
