Description

Technical Field

[0001] This utility model relates to the field of generator technology, and in particular to a dustproof and heat-dissipating generator. Background Technology

[0002] Generators have a wide range of applications in industrial and agricultural production, national defense, science and technology, and daily life. There are many types of generators, but their working principle is based on the laws of electromagnetic induction and electromagnetic force. Therefore, the general principle of their construction is to form magnetic circuits and electrical circuits that induce electromagnetic induction in each other in order to generate electromagnetic power and achieve the purpose of energy conversion.

[0003] A generator regulator generally refers to a voltage regulator. The voltage regulator is a crucial component assisting the generator in its operation. During normal vehicle operation, to ensure the generator voltage remains constant across different engine speeds and automatically adjusts with changes in generator speed to maintain a specific voltage range, a voltage regulator is necessary. This ensures the output voltage remains essentially constant under all engine operating conditions. The regulator typically operates by contacting the generator's rotor shaft with brushes, transmitting varying voltages to the shaft to control the rotor's magnetic field. However, existing generators have poor heat dissipation and dust protection for the regulator, and the connecting bolts are easily lost after the dust cover is removed, causing inconvenience in use.

[0004] How to improve dustproof performance and stability of the heatsink while ensuring its heat dissipation effect, and effectively prevent the loss of connectors and simplify the disassembly and assembly process when removing the dust cover, has become a technical problem that needs to be solved.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] To address the aforementioned shortcomings, the purpose of this invention is to provide a dustproof and heat-dissipating generator that, while ensuring the heat dissipation effect of the regulator's heat sink, improves dustproof performance and enhances the stability of the heat sink. Furthermore, when the dust cover is removed, it effectively prevents the loss of connecting parts and simplifies the disassembly and assembly steps of the dust cover.

[0007] To achieve the above objectives, this utility model provides a dustproof and heat-dissipating generator, including a generator body. The regulator heat sink of the generator body is provided with a dust cover connected to the end cover, and one end of the dust cover is provided with a clearance hole that cooperates with the regulator heat sink.

[0008] The dust cover is elastically connected with several rotatable connectors for connecting the dust cover and the end cap.

[0009] The dust cover at the clearance hole is symmetrically and elastically connected with a limiting plate.

[0010] According to the dustproof and heat-dissipating generator of this utility model, each of the connecting parts is provided with a connecting rod at one end near the end cover, and the end cover is provided with a plurality of connecting holes that cooperate with the connecting rod.

[0011] According to the dustproof and heat dissipation generator of this utility model, the end of the connecting member near the dust cover is inserted into the dust cover. A rotatable rotating ring is rotatably sleeved on the connecting member inside the dust cover. The rotating ring has symmetrical inserts. The dust cover has slots that cooperate with the inserts. The inserts are slidably disposed in the slots, and elastic members are provided between the inserts and the slots.

[0012] According to the dustproof and heat dissipation generator of this utility model, the dust cover is provided with a mounting groove at the end near the limiting plate, the limiting plate is inserted into the mounting groove at the end near the dust cover, and an elastic element is provided between the mounting groove and the limiting plate.

[0013] According to the dustproof and heat-dissipating generator of this utility model, the elastic element is a spring.

[0014] According to the dustproof and heat-dissipating generator of this utility model, the end of the limiting plate near the heat sink of the regulator is provided with an arc surface.

[0015] The purpose of this utility model is to provide a dustproof and heat-dissipating generator, including a dust cover. The dust cover improves dustproof performance while ensuring the heat dissipation effect of the regulator's heat sink. Symmetrical elastically connected limit plates are attached to the dust cover at the clearance holes. These limit plates press against elastic elements, increasing the pressure between the limit plates and the regulator's heat sink, thereby further ensuring the stability of the heat sink's fixation. When the dust cover is removed, after the connecting rods disengage from the connecting holes, the connecting parts automatically spring back under the action of the elastic elements at the insertion blocks, and the connecting parts will not detach from the dust cover, effectively preventing loss of the connecting parts and simplifying the disassembly and assembly steps of the dust cover. In summary, the beneficial effects of this utility model are: it improves dustproof performance and enhances the stability of the heat sink while ensuring the heat dissipation effect of the regulator's heat sink, and effectively prevents loss of the connecting parts when the dust cover is removed, simplifying the disassembly and assembly steps of the dust cover.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] See Figures 1-3 This utility model provides a dustproof and heat-dissipating generator, including a generator body 1. The structure and function of the generator body 1 are the same as those of the prior art, which are mature existing technologies in this field and will not be described in detail here. An regulator is provided on the end cover 11 of the generator body 1. The regulator is connected to a regulator heat sink 12 for heat dissipation. A dust cover 2 is provided on the regulator heat sink 12 and connected to the end cover 11. One end of the dust cover 2 is provided with a clearance hole that cooperates with the regulator heat sink 12. The regulator heat sink 12 can be exposed at the clearance hole to achieve the heat dissipation effect. Several connecting parts 3 are elastically connected to the dust cover 2. Each connecting part 3 is provided with a connecting rod 31 at the end near the end cover 11. The end cover 11 is provided with several connecting holes 13 that cooperate with the connecting rods 31. The connecting rods 31 are all threadedly connected to the connecting holes 13. The dust cover 2 is placed on the end cover 11, and the connecting parts 3 are pressed towards the side near the end cover 11. The connecting parts 3 are rotated so that the connecting rods 31 are all connected to the connecting holes 13, thus completing the fixation of the dust cover 2.

[0024] See Figures 1-3 Specifically, the end of the connector 3 near the dust cover 2 is inserted into the dust cover 2. A rotatable rotating ring 32 is rotatably fitted onto the connector 3 inside the dust cover 2 (there are various ways to rotatably connect the rotating ring 32 to the outside of the connector 3, such as adding a rotating bearing between them). Symmetrical inserts 33 are mounted on the rotating ring 32. The dust cover 2 has slots that mate with the inserts 33. The inserts 33 are slidably disposed within the slots, and elastic elements 34 are provided between the inserts 33 and the slots. Thus, the connector 3 can move vertically on the dust cover 2 (direction referenced). Figure 3 Furthermore, the connector 3 will not detach from the dust cover 2. During the vertical movement, the insert 33 presses against the elastic element 34. Due to the setting of the rotating ring 32, the connector 3 can rotate relative to the insert 33.

[0025] See Figures 1-3 Preferably, the dust cover 2 at the clearance hole is symmetrically and elastically connected with a limiting plate 4. The end of the dust cover 2 near the limiting plate 4 is provided with a mounting groove. The end of the limiting plate 4 near the dust cover 2 is inserted into the mounting groove. An elastic element 34 is provided between the mounting groove and the limiting plate 4, and the limiting plate 4 will not detach from the mounting groove. When the dust cover 2 is fastened on the regulator heat sink 12, the clearance hole is directly facing the regulator heat sink 12. As the dust cover 2 approaches the end cover 11, the limiting plate 4 abuts against the regulator heat sink 12. Since the position of the regulator heat sink 12 does not change, the limiting plate 4 retracts into the mounting groove. At the same time, the limiting plate 4 squeezes the elastic element 34, increasing the pressure between the limiting plate 4 and the regulator heat sink 12, thereby further ensuring the stability of the regulator heat sink 12.

[0026] See Figures 1-3 Preferably, the elastic element 34 is a spring, which provides return power.

[0027] See Figures 1-3 Preferably, the end of the limiting plate 4 near the regulator heat sink 12 is provided with an arc surface to reduce the friction force generated when the limiting plate 4 contacts the regulator heat sink 12.

[0028] See Figures 1-3 During installation, place the dust cover 2 on the end cover 11, with the limiting plates 4 abutting against the regulator heat sink 12. Press the connector 3 towards the side closest to the end cover 11 and rotate the connector 3 so that the connecting rods 31 are connected to the connecting holes 13, thus completing the fixing of the dust cover 2. To disassemble, simply rotate the connector 3 in the opposite direction. When the connecting rods 31 are disengaged from the connecting holes 13, the connector 3 will automatically spring back under the action of the elastic element 34 at the insert block 33, and the connector 3 will not detach from the dust cover 2, effectively preventing the connector 3 from being lost.

[0029] This utility model provides a dustproof and heat-dissipating generator, including a dust cover. The dust cover improves dustproof performance while ensuring the heat dissipation effect of the regulator's heat sink. Symmetrical elastically connected limit plates are attached to the dust cover at the clearance holes. These limit plates press against elastic elements, increasing the pressure between the limit plates and the regulator's heat sink, thereby further ensuring the stability of the heat sink. When the dust cover is removed, after the connecting rods disengage from the connecting holes, the connecting parts automatically spring back under the action of the elastic elements at the insertion blocks, and the connecting parts will not detach from the dust cover, effectively preventing loss of the connecting parts and simplifying the disassembly and assembly steps of the dust cover. In summary, the beneficial effects of this utility model are: it improves dustproof performance and enhances the stability of the heat sink while ensuring the heat dissipation effect of the regulator's heat sink, and effectively prevents loss of the connecting parts when the dust cover is removed, simplifying the disassembly and assembly steps of the dust cover.
