Technical Field

[0001] The utility model relates to the technical field of heat dissipation of planetary reduction starters, in particular to a heat dissipation casing for planetary reduction starters. Background Art

[0002] A planetary reduction starter is a starter with a gear reducer between the armature shaft and the drive gear of the starter. There are many types of gear reducers for this type of starter, including external meshing, internal meshing, and planetary gear types. The main function of a reduction starter is to start the engine, especially in gasoline and diesel engines. It has replaced the early manual engine starter.

[0003] The planetary reduction starter often generates a high temperature during use, so it is necessary to add a heat dissipation shell to ensure its heat dissipation effect and avoid damage to internal parts due to high temperature;

[0004] The heat dissipation housing in the existing technology is usually simple in structure, with only air holes opened on the housing to achieve the effect of internal air circulation. Although this method can achieve a certain heat dissipation effect, dust and other debris can easily enter the interior, and the dustproof effect is poor. In order to achieve the dustproof effect, some heat dissipation housings will add filters to block dust, but after long-term use, the filters are easily clogged and affect the heat dissipation effect; and this heat dissipation method cannot speed up the air flow inside, and the heat dissipation effect is poor. Therefore, a heat dissipation housing for a planetary reduction starter is proposed to solve the above problems. Utility Model Content

[0023] 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.

[0024] Embodiment 1:

[0025] See also Figure 1-5 In this embodiment, a heat dissipation casing for a planetary reduction starter includes a protective shell 1, which is characterized in that: a plurality of support platforms 11 are arranged inside the protective shell 1, and a card slot 12 is opened on the support platform 11. A starter 2 is arranged inside the protective shell 1, and a card block 21 matching the number of the support platforms 11 is arranged on the starter 2, and the card blocks 21 are all connected to the card slot 12; this connection method can effectively ensure its convenience during the installation process, and the installation effect can be completed by connecting the card block 21 on the starter 2 to the card slot 12, which is convenient for subsequent maintenance or replacement.

[0026] In order to achieve the effect of ventilation and heat dissipation, the left end of the protective shell 1 in this embodiment is provided with a first heat dissipation cover 13, the right end of the protective shell 1 is provided with a second heat dissipation cover 14, and the second heat dissipation cover 14 is provided with a filter 15; by providing the first heat dissipation cover 13 and the second heat dissipation cover 14, air circulation inside the protective shell 1 can be achieved during use; by providing the filter 15, it can effectively block dust and effectively prevent dust from entering and causing damage to the inside. Further, in the actual use process, the staff can also add a filter 15 to the first heat dissipation cover 13 to ensure that it has a better dust-proof effect.

[0027] In order to increase the heat dissipation effect, a transmission shaft 22 is provided on one side of the starter 2 in this embodiment, and an exhaust fan 23 and a transmission gear 24 are provided on the transmission shaft 22. A driven gear 25 is rotatably connected to the other side of the starter 2, and a connecting shaft 26 is provided on the driven gear 25. The other end of the connecting shaft 26 passes through the second heat dissipation cover 14 and the filter screen 15 and is fixedly connected to a cleaning brush 27. A connecting seat 28 is provided on the starter 2, and a linkage assembly 3 is rotatably connected in the connecting seat 28.

[0028] As a preferred technical solution in this embodiment, during actual use, the staff can control the starter 2 to drive the transmission shaft 22 to rotate. During the rotation of the transmission shaft 22, the exhaust fan 23 can be effectively driven to rotate. During the rotation of the exhaust fan 23, the air circulation inside the protective shell 1 can be accelerated, thereby effectively taking away the heat generated by the starter 2 during use. It is worth noting that during the process of the starter 2 controlling the transmission shaft 22 to rotate, the wind force generated by the exhaust fan 23 is directed toward the transmission shaft 22. This external air enters the interior of the starter 2 from the second heat dissipation cover 14, and the air inside the starter 2 is discharged from the first heat dissipation cover 13. At this time, the filter 15 can effectively filter out dust and debris in the air, thereby ensuring that it can play a good dust removal effect in the process of dissipating heat from the starter 2.

[0029] Embodiment 2:

[0030] See also Figure 6 In order to achieve the effect of cleaning the filter screen 15, the linkage assembly 3 in this embodiment is provided with an electric push rod 31, which is rotatably connected to the connecting seat 28. The push rod end of the electric push rod 31 is fixedly connected to a transmission gear rod 32. One end of the electric push rod 31 away from the transmission gear rod 32 is fixedly connected to a driven gear rod 33, and the driven gear rod 33 is kept in mesh with the driven gear 25.

[0031] This connection method can effectively facilitate the staff to control the cleaning effect of the filter 15. Specifically, in actual use, the staff can control the electric push rod 31 to make the push rod end drive the transmission gear rod 32 to move until the transmission gear rod 32 is meshed with the exhaust fan 23. When it is meshed, the staff can control the transmission shaft 22 to rotate. During the dust removal process, the transmission shaft 22 should rotate in the opposite direction so that the wind force generated by the exhaust fan 23 is directed toward the second heat dissipation cover 14, so that it can clean the filter 15. The attached dust can be initially blown off; at the same time, during the rotation of the transmission shaft 22, the transmission gear rod 32 and the electric push rod 31 can be driven to rotate, and during the rotation of the electric push rod 31, the driven gear rod 33 can be effectively driven to rotate the driven gear 25, and during the rotation of the driven gear 25, the cleaning brush 27 can be driven to rotate. During the rotation of the cleaning brush 27, the dust attached to the filter 15 can be swept off, and the wind force generated by the exhaust fan 23 can blow out the swept dust, thereby ensuring the cleaning effect of the filter 15.

[0032] In order to achieve the control effect of the connection seat 28, a plc controller 34 is provided on the connection seat 28 in this embodiment, and the plc controller 34 is used to control the extension and retraction of the electric push rod 31. During use, the staff can control the extension and retraction of the electric push rod 31 in a timely manner through the plc controller 34, thereby achieving the effect of cleaning the filter 15 in a timely manner, avoiding the need for manual adjustment by the staff, and facilitating subsequent use.

[0033] The working principle of the above embodiment is:

[0034] 1. When it is necessary to dissipate heat inside the starter 2, the staff can control the starter 2 to drive the transmission shaft 22 to rotate. During the rotation of the transmission shaft 22, the exhaust fan 23 can be effectively driven to rotate. During the rotation of the exhaust fan 23, the air circulation inside the protective shell 1 can be accelerated, thereby effectively taking away the heat generated by the starter 2 during use. It is worth noting that during the process of the starter 2 controlling the transmission shaft 22 to rotate, the wind force generated by the exhaust fan 23 is directed toward the transmission shaft 22. This external air enters the interior of the starter 2 from the second heat dissipation cover 14, and the air inside the starter 2 is discharged from the first heat dissipation cover 13. At this time, the filter 15 can effectively filter out dust and debris in the air, thereby ensuring that it can play a good dust removal effect in the process of dissipating heat from the starter 2.

[0035] 2. When the filter 15 needs to be cleaned, the staff can control the electric push rod 31 so that the push rod end drives the transmission gear rod 32 to move until the transmission gear rod 32 is meshed with the exhaust fan 23. After the meshing occurs, the staff can control the transmission shaft 22 to rotate. During the dust removal process, the transmission shaft 22 should rotate in the opposite direction so that the wind force generated by the exhaust fan 23 is directed toward the second heat dissipation cover 14, so that it can initially blow off the dust attached to the filter 15; at the same time, during the rotation of the transmission shaft 22, the transmission gear rod 32 and the electric push rod 31 can be driven to rotate. During the rotation of the electric push rod 31, the driven gear rod 33 can be effectively driven to rotate the driven gear 25. During the rotation of the driven gear 25, the cleaning brush 27 can be driven to rotate. During the rotation of the cleaning brush 27, the dust attached to the filter 15 can be swept off, and the swept dust can be blown out by the wind force generated by the exhaust fan 23, thereby ensuring the cleaning effect of the filter 15.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
