Abstract

The present invention relates to the technical field of motor wiring mechanisms, and specifically to a high-reliability motor based on an inward-retracting wiring mechanism, comprising a junction box, wherein the junction box comprises a box slot shell, a unit node device, an exhaust duct, an air inlet integration, a double-headed electric sheet group, an inner wire, a single-headed electric sheet, an outer wire and a node frame. Compared with the traditional motor junction box where two conductive sheets are in contact and energized and there is a hidden danger of overheating, the present invention uses a double-headed electric frame and a single-headed electric sheet to contact and energize. A conductive sheet on the double-headed electric frame and one side of the single-headed electric sheet are elastically in contact and energized to cope with motor vibration. Another spare conductive sheet on the double-headed electric frame is separated from the single-headed electric sheet, and the spare conductive sheet of the double-headed electric frame and the new side of the single-headed electric sheet are covered with protective plates to prevent the appearance of dust and oxide layers. If the energized conductive sheet accidentally overheats, the spare conductive sheet automatically contacts the new side of the single-headed electric sheet, thereby solving the problem of overheating and ensuring that the power transmission of the motor is not affected.

Description

Technical Field

[0001] The present invention relates to the technical field of motor connection mechanisms, and in particular to a high-reliability motor based on an inward-retracting connection mechanism. Background Art

[0002] In traditional motor junction boxes, the inner wire conductive plate and the outer wire conductive plate are tightened and fixed by bolts. Such rigid contact of the conductive plates is easily affected by vibration and shock. When the bolts are loose, elastic pressure can be applied to the two conductive plates in contact. In this way, the conductive plates on both sides are in elastic contact. The conductive plates are instantly separated under vibration and shock, but can be quickly fitted together under the support of elastic force. The instantaneous reaction does not affect the normal power supply of the motor, but there are deficiencies in the elastic connection of the conductive plates.

[0003] The motor junction box needs to dissipate heat and cool down. The ventilation in the motor is led into the junction box. In this way, ventilation and heat dissipation can cool down the junction box, but it cannot solve the problem of accidental overheating. The motor itself will generate certain vibrations during operation. The vibration causes unstable contact between the inner conductive plate and the outer conductive plate. Air and dust have the opportunity to invade between the two conductive plates. The surface of the heating part of the conductive plate is easily oxidized, forming an oxide layer that hinders power flow. The oxide layer is a poor conductor. The oxide layer increases resistance and reduces the overall conductivity of the material. Therefore, the conductive plate needs to be replaced to avoid the conductive effect caused by the oxide layer. In addition, during the ventilation process inside the junction box, it is more likely for dust to erode between the two conductive plates, which will also cause the problem of temperature rise during power transmission. Therefore, the influence of the oxide layer and the dust layer will cause the conductive plate to overheat.

[0004] Conventional ventilation and heat dissipation cannot solve the problem of accidental overheating of the conductive sheet. For this reason, the present invention provides a high-reliability motor based on an inward-retracting wiring mechanism. Summary of the Invention

[0005] The object of the present invention is to provide a high-reliability motor based on an inward-retracting wiring mechanism to solve the problems raised in the above-mentioned background technology.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. Compared with the traditional motor junction box where two conductive plates are in contact and energized, which has the risk of overheating, the present invention uses a double-headed electric frame and a single-headed electric plate to contact and energize. One conductive plate on the double-headed electric frame is elastically in contact with one side of the single-headed electric plate to energize, which can cope with motor vibration. The other spare conductive plate of the double-headed electric frame is separated from the single-headed electric plate, and the spare conductive plate of the double-headed electric frame and the new side of the single-headed electric plate are covered with protective plates to prevent the appearance of dust and oxide layer. If the energized conductive plate accidentally overheats, the spare conductive plate automatically contacts the new side of the single-headed electric plate, which solves the problem of overheating and ensures that the power transmission of the motor is not affected.

[0028] 2. The present invention prevents accidental overheating of the connection points by detecting the temperature of the single-end circuit board and the double-end circuit frame. In addition, air is introduced into the box slot shell to blow away the heat retained in the box slot shell, ensuring that the operating temperature of the junction box is controlled within a safe range.

[0060] refer to Figure 8 It is understood that the active component 18 includes a multi-control frame 32 fixed on the node frame 11, a worm 33 and a vertical shaft 34 supported on the multi-control frame 32, and a pressure group 31 driven on one side of the worm 33. One end of the vertical shaft 34 is connected to the bevel gear fixed on the worm 33 through a fixed bevel gear for direction transmission, and the other end of the vertical shaft 34 is connected to the gear fixed on one end of the neck shaft 24 through a fixed shaft gear. The other end of the neck shaft 24 is connected to the gear fixed on the end of the split shaft 23 by axial movement of the fixed gear.

[0061] The triggering group 31 includes a central control shaft 35 that is movably sleeved in a circular hole opened on the multi-control frame 32, a disc gear 36 fixedly sleeved on the central control shaft 35, a flat support plate 37 that is movably sleeved on the outside of the central control shaft 35, an outer ring gear 39 fixed on one side of the flat support plate 37, and a mainspring 38 connected between the outer ring gear 39 and the central control shaft 35. The disc gear 36 and the worm 33 are engaged in a transmission connection.

[0062] The semi-moving part 19 includes a transverse rack 41, an axis control group 40 that establishes transmission between the transverse rack 41 and the outer ring gear 39, two direction columns 44 vertically fixed at one end of the transverse rack 41, a spring 43 sleeved on the direction column 44, and a protective plate 42 that contacts both ends of the spring 43, and the direction column 44 slides through a through hole opened on the protective plate 42.

[0063] One side of the single-headed electrical sheet 9 is in contact with a metal sheet on the double-headed electrical frame 14 and is energized. Two layers of separate ring sheets are placed between the other side of the single-headed electrical sheet 9 and another metal sheet on the double-headed electrical frame 14, and each layer of ring sheets is composed of half ring sheets on two protective plates 42.

[0064] The axis control group 40 includes a side plate frame 45 with one end fixed on the node frame 11, a side shaft 48 movably sleeved in a through hole opened on the side plate frame 45, a side gear 49 fixed at one end of the side shaft 48, a C-shaped spring clip 46 fixed on the side plate frame 45, and a limit block 47 fixed on the cross rack 41. The side gear 49 establishes a meshing transmission between the cross rack 41 and the side gear 49, and the C-shaped spring clip 46 is positioned to intercept the limit block 47. The side plate frame 45 is clamped into the T-shaped slot opened on the cross rack 41 by setting a T-shaped column.

[0065] When the motor body 1 is working, the junction box 2 plays the function of transmitting current, and the temperature inside the junction box 2 will also rise. Therefore, when the junction box 2 is operating normally, the heat is blown away by injecting heat dissipation airflow into the box tank shell 3. Specifically, air is blown into the box tank shell 3 through the air inlet pipe 15, and the original hot air in the box tank shell 3 is squeezed out. Specifically, the hot air flow converges and is injected into the C-type exhaust pipe 20. Figure 5 and Figure 9 Understand the position of the C-type exhaust duct 20. The hot air injected into the C-type exhaust duct 20 will be discharged back into the motor body 1 through the exhaust duct 5, and subsequently discharged through the heat dissipation exhaust port in the motor body 1. The expansion medium in the C-type empty tube 30 can be a gas that is sensitive to thermal expansion and contraction. The normal contact between the single-headed electric sheet 9 and the double-headed electric frame 14 will not cause excessive heating of the surrounding air. If the single-headed electric sheet 9 and the double-headed electric frame 14 accidentally dissipate too much heat, the heat is transferred to the C-type empty tube 30, and the air pressure in the C-type empty tube 30 rises. The air pressure causes the telescopic column 29 to extend, and the telescopic column 29 drives the neck shaft 24, and the neck shaft 24 moves axially. Originally, the neck shaft 24 and the sub-shaft 23 did not interfere with each other. The accidental overheating causes the neck shaft 24 and the sub-shaft 23 to establish an engaged transmission, and the subsequent transmission will trigger the replacement of the conductive sheet.

[0066] The external wire 10 is connected to the external power supply, and the current path passes through the single-end electric sheet 9, a metal sheet on the double-end electric frame 14, the L-shaped plate on the double-end electric frame 14, the S-shaped metal spring 13, the conductive plate 12 and the internal wire 8, and then the current is introduced into the motor body 1. As the power-on time increases, the temperature at the junction of a conductive sheet of the double-end electric frame 14 and the single-end electric sheet 9 rises. If an oxide layer or dust layer appears between the two, continuing to transmit power will cause excessive heating between the double-end electric frame 14 and the single-end electric sheet 9. As mentioned before, excessive heating will cause the neck shaft 24 to move axially, and the neck shaft A meshing transmission is established between 24 and the sub-shaft 23. The wind wheel 16 at the power source rotates continuously under the blowing of the conveying airflow, and then transmits the sub-shaft 23 through the wheel shaft 17, and then transmits the vertical shaft 34 through the neck shaft 24, and then transmits the disc gear 36 through the worm 33, and then the central control shaft 35 rotates slowly to cause the mainspring 38 to contract and store power. After the mainspring 38 stores enough power, the blocking state between the C-shaped spring 46 and the limit block 47 is broken, and then the mainspring 38 releases power, and the outer gear ring 39 rotates to drive the side gear 49 to rotate, thereby driving the horizontal rack 41 to translate. Figure 13 , the two opposite horizontal racks 41 move away from each other, the horizontal rack 41 drives the steering column 44, and then pulls the protective plate 42, the two layers of ring plates between the double-headed electric frame 14 conductive plate and the single-headed electric plate 9 disappear, because the two opposite protective plates 42 are separated, refer to Figure 12 After the conductive sheet below the double-headed electric frame 14 and the single-headed electric sheet 9 overheat, the protective plate 42 between the conductive sheet above the double-headed electric frame 14 and the upper surface of the single-headed electric sheet 9 is pulled out, so that the conductive sheet above the double-headed electric frame 14 descends to contact the single-headed electric sheet 9 that is stationary in space, establishing a new conductive position. The power for the double-headed electric frame 14 to descend comes from the push of the S-shaped metal spring 13, and the overheated conductive sheet below the double-headed electric frame 14 and the overheated lower surface of the single-headed electric sheet 9 are separated and powered off.

[0067] Here, the upper surface of the single-headed electrical sheet 9 is covered by a protective plate 42 to prevent the formation of an oxide layer or a dust layer. The lower surface of the conductive sheet above the double-headed electrical frame 14 is also covered by another protective plate 42. Therefore, the process of pulling out the protective plate 42 is equivalent to removing a layer of outer film between the double-headed electrical frame 14 and the single-headed electrical sheet 9. In this way, the conductive sheet on the new double-headed electrical frame 14 and the upper surface of the new single-headed electrical sheet 9 can safely contact and be energized, and the overheating problem is solved.

[0068] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
