Description
Technical field:
The utility model relates to a kind of carbon brush motor, particularly a kind ofly can detect its carbon brush degree of wear and and then the suggestion device changed of prompting user.
Background technology:
In the prior art, the carbon brush structure on the engine commutator generally comprises brush carrier, is slidably mounted in carbon brush and alarm lamp in the brush carrier inner chamber, and carbon brush one end top has elastic component, and the other end contacts with the circumferential surface of commutator.Carbon brush withstands on the commutator under the effect of flexible member always, for the degree of wear of monitoring carbon brush so that in time change carbon brush, in carbon brush, be embedded with wire, when having slided into desired location after the carbon brush wearing and tearing, wire exposes and makes alarm lamp shinny, this technical scheme makes carbon brush bury manufacturing process more complicated wiry underground, and is therefore practical inadequately.Another kind of technical scheme is that the desired location at carbon brush has the hole, one side of carbon brush is provided with light-emitting component, opposite side is provided with receiving element, after the carbon brush wearing and tearing have moved to desired location, receiving element can make alarm lamp report to the police by the light that the hole receives light-emitting component, but described hole is very easily stopped up by dust and is blocked light path, causes warning malfunctioning.
The utility model content:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of carbon brush wearing and tearing suggestion device simple, that use is reliable, cheap for manufacturing cost of making is provided.
The carbon brush wearing and tearing suggestion device that provides according to the utility model, comprise brush carrier, carbon brush, metal spring, briquetting and alarm lamp, carbon brush can slide up and down to be inlaid in the brush carrier, its lower end contacts with the circumferential surface of engine commutator, the upper end is replaced mutually with metal spring, and briquetting is pressed on the metal spring upper end.Described brush carrier is provided with a sensing chip by lower end position, and this sensing chip and power supply one end join, and the described metal spring and the power supply other end join, and described alarm lamp and sensing chip are connected with in the metal spring any one.Described sensing chip can be after carbon brush may wear to a certain degree, and contacting and form the loop with the metal spring that moves down makes alarm lamp shinny.
The utility model also has following attached technical characterictic:
Described alarm lamp links together by lead and sensing chip, also is serially connected with rectifier diode and current-limiting resistance on it.
The lower end perisporium of described brush carrier is provided with axial hook groove, and described sensing chip is installed in this axial hook groove, which is provided with the contact that is the horizontal projection shape.
Described contact is to the distance in the brush carrier axle center radius less than metal spring.
Described carbon brush is designed to rectangular-shaped.
According to the carbon brush wearing and tearing suggestion device that the utility model provides, prior art has following advantage relatively:
The utility model utilizes the characteristic of metal spring for conductor, and form the loop by its sensing chip and make alarm lamp shinny with same conduction, thereby very reliable.Simultaneously, sensing chip directly is fastened on the brush carrier perisporium, imbeds manufacture craft in the carbon brush with respect to wire in the prior art, and is simple and practical.In addition, metal spring impels carbon brush to replace all the time at the commutator circumferential surface on the one hand, becomes the important ring of prompting in the loop on the other hand, and dual-use material has reduced the production cost of this device.
Description of drawings:
Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation according to carbon brush wearing and tearing suggestion device described in the utility model;
Fig. 2 is the circuit diagram according to carbon brush wearing and tearing suggestion device described in the utility model.
Embodiment:
See figures.1.and.2, the carbon brush wearing and tearing suggestion device that provides according to the utility model, comprise brush carrier 1, carbon brush 2, metal spring 3, briquetting 4 and alarm lamp LED, carbon brush 1 can slide up and down to be inlaid in the brush carrier 2, its lower end contacts with the circumferential surface of engine commutator 6, the upper end is replaced mutually with metal spring 3, and briquetting 4 is pressed on metal spring 3 upper ends.Brush carrier 1 is provided with a sensing chip 7 by lower end position, and sensing chip 7, alarm lamp LED join by lead and power supply one end, and metal spring 3 joins by the lead and the power supply other end.In carbon brush 2 wear processes, metal spring 3 moves down thereupon, and after carbon brush 2 may wear to a certain degree, sensing chip 7 can contact with the metal spring 3 that moves down and form the loop and make alarm lamp LED shinny, in time changes carbon brush with the prompting user.
As mentioned above, the lower end perisporium of described brush carrier 1 is provided with axial hook groove 11, and sensing chip 7 is installed in this axial hook groove 11, and also is provided with the contact 71 of curved convex on it, and this contact 71 is slightly less than the radius of metal spring 3 to the distance in brush carrier 1 axle center.So, metal spring 3 is after touching contact 11, sensing chip 7 is understood the distortion that outwards produces trace under the effect of self elastic force, therefore 7 meetings of sensing chip contact with metal spring 3 surfaces, and can not stop that it moves down, obtaining the prompting of alarm lamp LED as the user after, even if in time do not change carbon brush 2, carbon brush 2 also still can keep in touch with commutator 6 surfaces under the effect of metal spring 3, can also normally use with the motor of guaranteeing this moment.
As shown in Figure 2, alarm lamp LED one end is serially connected with rectifier diode DA and current-limiting resistance R6, the brightness that can improve indicator light by this rectifier diode DA and current-limiting resistance R6.
Described carbon brush 2 is designed to rectangular-shaped, and therefore carbon brush can not contact with the contact 71 on the sensing chip 7 in folding process.
The foregoing description is only for the usefulness that the utility model is described; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
