Description

Technical Field

[0001] This utility model relates to the field of generator technology, and in particular to a generator that is easy to disassemble and dissipates heat. Background Technology

[0002] In recent years, the proportion of new energy vehicles has been increasing. The generator is the main power source of the car. When the engine is running normally, it supplies power to all electrical equipment and charges the battery at the same time.

[0003] The announcement number CN217469625U describes a UPS-specific permanent magnet synchronous generator, which includes a generator body. A support base is fixedly connected to the bottom of the generator body. A protective shell is movably connected to one side of the generator body. A dustproof mechanism is provided on one side of the protective shell. The dustproof mechanism includes a dustproof net. The surface of the dustproof net contacts the inner wall of the protective shell. A guide block is fixedly connected to the surface of the dustproof net.

[0004] Based on the above technical features, the problem is that in the existing technology, the process of disassembling and assembling the protective shell is relatively cumbersome and the use is unchanged. At the same time, the dustproof mechanism is easily covered by debris, which affects the overall heat dissipation.

[0005] Therefore, it is necessary to solve the above problems by using a generator that is easy to disassemble and dissipates heat. Utility Model Content

[0006] The purpose of this invention is to provide a generator that is easy to disassemble and dissipates heat, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a generator that is easy to disassemble and dissipates heat, including a housing, a protective cover fastened to the rear of the housing, an air inlet hole opened at the center of the protective cover, and a filter screen installed inside the air inlet hole; the filter screen is provided with multiple protrusions protruding outward from the housing; the protective cover is provided with quick-release parts, which are limited and cooperate with the housing.

[0008] Preferably, the quick-release component includes two wedge-shaped locking blocks, which are radially opposed along the output shaft of the generator and are both in a limiting sliding fit with the protective cover; the housing has two slots that match the wedge-shaped locking blocks, with the two wedge-shaped locking blocks corresponding to the two slots one by one, and each wedge-shaped locking block engaging and limiting the corresponding slot.

[0009] Preferably, the inclined surfaces of both wedge-shaped blocks are in sliding contact with the housing, and a return spring is fixedly provided between the two wedge-shaped blocks and the protective cover.

[0010] Preferably, each of the two wedge-shaped blocks is fixedly provided with a pull rod.

[0011] Preferably, two limiting rods are fixedly installed at the tail of the housing. Both limiting rods are parallel to the output shaft of the generator and symmetrical about the output shaft of the generator. Two limiting holes are opened on the protective cover. The two limiting holes correspond one-to-one with the two limiting rods, and each limiting rod passes through the corresponding limiting hole.

[0012] Preferably, the filter screen is fixedly installed in an annular fixing frame, which is located inside the air inlet; the protective cover is threadedly connected to two opposing bolts, with the annular fixing frame located between the two bolts, and both bolts abutting and limiting the engagement with the annular fixing frame.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] First, the filter screen of this utility model has protrusions, so when large debris is adsorbed onto the filter screen, the filter pores on the filter screen will not be covered by a large amount, thereby reducing the impact on the heat dissipation of the generator. At the same time, quick-release parts are used to reduce the difficulty of disassembling and assembling the protective cover.

[0015] Secondly, the quick-release component of this utility model includes a wedge-shaped locking block. When disassembling or assembling the protective cover, simply pull the wedge-shaped locking block to slide it, which is convenient and quick.

[0016] Third, this utility model uses a reset spring to reset the wedge-shaped block, so that when installing the protective cover, there is no need to manually pull the wedge-shaped block, thus improving the installation efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1 to 5 The generator shown is easy to disassemble and dissipates heat, and includes a housing 1. A fixing bracket 2 is welded to the bottom of the housing 1, through which the generator can be installed in a predetermined position.

[0025] The output shaft 4 is rotatably installed inside the housing 1, and the rotor 3 is fixedly installed on the output shaft 4. At the same time, the fan blade 5 is coaxially fixedly connected to the output shaft 4.

[0026] A water-cooling pipe 6 is fixedly installed inside the housing 1. The water-cooling pipe 6 is spiral in shape. The inlet and outlet of the water-cooling pipe 6 are both located outside the housing 1. This water-cooling technology is existing technology and will not be described in detail here.

[0027] A protective cover 7 is fastened to the tail of the housing 1. The protective cover 7 is used to protect the fan blades 5.

[0028] A quick-release mechanism is installed on the protective cover 7. The quick-release mechanism engages with the housing 1 to secure the protective cover 7 to the housing 1. The quick-release mechanism includes two wedge-shaped locking blocks 8, which are radially opposed to each other along the output shaft 4.

[0029] Two mounting blocks 16 are fixedly installed on the protective cover 7. The two mounting blocks 16 are integrally formed with the protective cover 7. At the same time, the interior of each mounting block 16 is provided with a sliding groove along the radial direction of the output shaft 4. Each sliding groove communicates with the interior of the protective cover 7, and a wedge-shaped locking block 8 slides and engages in each sliding groove.

[0030] Two slots 12 are provided on the housing 1, and the two slots 12 correspond one-to-one with two wedge-shaped blocks 8. Each wedge-shaped block 8 is engaged and limited in fit with the corresponding slot 12. This is used to limit the axial movement of the protective cover 7 along the output shaft 4.

[0031] A pull rod 11 is welded to each of the two opposing ends of the wedge-shaped blocks 8 to facilitate pulling the wedge-shaped blocks 8.

[0032] Both mounting blocks 16 have mounting grooves, and the mounting grooves and sliding grooves within the same mounting block 16 are interconnected and intersect each other. Each mounting groove has two connecting plates 9 that are limited and slidably fitted. The wedge-shaped locking blocks 8 located within the same mounting block 16 are fixedly connected to the two connecting plates 9, and the two connecting plates 9 are symmetrically distributed about the wedge-shaped locking blocks 8 they are connected to.

[0033] Two return springs 10 are installed in each mounting slot along the sliding direction of the wedge-shaped locking block 8, and the two return springs 10 correspond one-to-one with the two connecting plates 9. One end of each return spring 10 is fixedly connected to the protective cover 7, and the other end of each return spring 10 is fixedly connected to the corresponding connecting plate 9.

[0034] The inclined surfaces of the two wedge-shaped blocks 8 are in sliding contact with the housing 1.

[0035] Two limiting rods 13 are welded and fixed to the tail of the housing 1. The two limiting rods 13 are parallel to the output shaft 4 and symmetrical about the output shaft 4. Two limiting holes 14 are opened on the protective cover 7. The two limiting rods 13 correspond one-to-one with the two limiting holes 14, and each limiting rod 13 is inserted into the corresponding limiting hole 14. This is used to limit the rotation of the protective cover 7.

[0036] An air inlet is provided at the center of the protective cover 7, and a filter 15 is installed inside the air inlet. The filter 15 is fixedly installed in an annular fixing frame located inside the air inlet. Two bolts 17 for clamping are threaded onto the protective cover 7, and the two bolts 17 are radially opposite each other along the output shaft 4.

[0037] Two bolts 17 are inserted into the air inlet and engage with the annular fixing frame for limiting and positioning.

[0038] The filter screen 15 has multiple protrusions that extend outward from the housing 1 to prevent debris from covering the filter holes on the filter screen 15.

[0039] Working principle: When installing the protective cover 7, first align the two limiting holes 14 on the protective cover 7 with the two limiting rods 13 at the tail of the housing 1. Then push the protective cover 7 closer to the tail of the housing 1.

[0040] When the two wedge-shaped blocks 8 come into contact with the housing 1, the housing 1 pushes the two wedge-shaped blocks 8 to slide away until the near ends of the two wedge-shaped blocks 8 slide against the outer surface of the housing 1. During this process, the inclined surfaces of the two wedge-shaped blocks 8 slide against the tail of the housing 1, and each connecting plate 9 stretches the connected return spring 10.

[0041] As the protective cover 7 is continuously pushed, the two wedge-shaped blocks 8 slide into their corresponding slots 12 and engage with them. During this process, all the return springs 10 retract and drive the wedge-shaped blocks 8 to slide via the connecting plate 9.

[0042] At the same time, the two limiting rods 13 are inserted into the corresponding limiting holes 14.

[0043] After installing the protective cover 7, place the annular fixing frame inside the air inlet. Then tighten the two bolts 17 until they are firmly against the annular fixing frame. This completes the installation of the filter screen 15.

[0044] When the generator is used, if debris is adsorbed onto the filter screen 15, the protrusions on the filter screen 15 support the debris and prevent the debris from covering too many filter pores.

[0045] When removing the protective cover 7, pull both levers 11 simultaneously. The levers 11 will cause the wedge-shaped locking blocks 8 to slide out of the corresponding slots 12. Then, maintain the pulling force on the levers 11 and pull the protective cover 7 out along the axial direction of the output shaft 4.

[0046] When disassembling the filter screen 15, turn the two bolts 17 in the opposite direction to disengage them from the annular fixing frame. Then, remove the annular fixing frame and the filter screen 15.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
