Abstract

The invention discloses a novel carbon brush base. The novel carbon brush base comprises a base body and a spring arranged in the base body, and further comprises a mounting rack and a plate body, wherein the mounting rack is erected on an outer shell of the base body, and the plate body is mounted in the mounting rack through an extensible connection portion. A through hole is formed in a position, corresponding to the installation position of the plate body, of the outer shell, and the plate body enters the base body through the through hole. An alarm device comprising an audible alarm unit is arranged in a mounting groove formed in the inner wall of the bottom of the base body and corresponds to the position of the plate body, and a switch of the alarm device right faces the lower end portion of the plate body. The novel carbon brush base has traditional functions and meanwhile can prompt the outside to replace carbon brushes and protect a commutator against damage.

Description

The New Type of Carbon brush holder

Technical field

The present invention relates to the carbon brush used for electric engine seat, particularly a kind of New Type of Carbon brush holder.

Background technology

Carbon brush holder is the important component part of a whole set of carbon brush mechanism in the motor, and it is installed on above the total carbon brush holder that is disk or other shapes usually, and carbon brush is then placed in this carbon brush holder.

After carbon brush used a period of time, its carbon piece part will be worn and torn, and namely its length will shorten, and at this moment just need to change timely carbon brush, otherwise just might damage commutator, causes the fault of motor.But, to change now carbon brush and a lot all be with workman's subjective judgement or directly observe motor internal and need to determine whether to change, this will produce very many hidden danger, as owing to in time find to need the carbon brush of replacing to cause commutator fault etc.

Therefore, in conjunction with present problem, if a kind of novel carbon brush holder can be provided, make it when traditional function is provided, the situation that can also change carbon brush to needs will reduce the existing existing hidden danger of mode so greatly in time to external world's notice.

Summary of the invention

Purpose of the present invention is exactly for the problems referred to above, provides a kind of and can in time remind the extraneous New Type of Carbon brush holder of noting changing carbon brush.

To achieve these goals, the invention provides following technical scheme: the New Type of Carbon brush holder, it comprises pedestal and is installed on the interior spring of this pedestal that it also comprises:

Installing rack, it is set up on the shell of above-mentioned pedestal;

Plate body, it is installed in the above-mentioned installing rack by an extensile connecting portion, above-mentioned shell

Upper installation site that should plate body is also offered a through hole, this plate body enters in the above-mentioned pedestal by this through hole;

Include the warning device of audible alarm unit, the position of its corresponding above-mentioned plate body is arranged in the mounting groove on the above-mentioned pedestal bottom interior wall, and the switch of this warning device is over against the bottom of above-mentioned plate body.

Further, above-mentioned connecting portion is spring or connecting rod.

Further, above-mentioned warning device also comprises the electric light alarm unit.

Further, the bottom of above-mentioned plate body extends to form protuberance along the thickness direction of plate body to both sides.

Adopt the beneficial effect of above technical scheme to be: after the length reduction of carbon brush arrives to a certain degree, plate body can enter in the pedestal and rely on the extensional process of connecting portion to fall to the warning device place, and trigger switch, open the audible alarm unit of warning device and report to the police, remind the extraneous carbon brush of noting changing; This carbon brush holder can also in time be reminded the extraneous carbon brush of noting changing when traditional function is provided, the protection commutator is not damaged.

Fig. 2 is structural representation Fig. 2 of New Type of Carbon brush holder of the present invention.

Wherein, 1. 211. protuberances, 3. installing racks, 4. connecting portions, 5. warning devices, 51. audible alarm unit, pedestal 11. through holes 12. springs 13. mounting grooves, 2. plate bodys, 21. bottoms, 52. switches, 53. electric light alarm units, 6. carbon brush.

Embodiment

Describe preferred implementation of the present invention in detail below in conjunction with accompanying drawing.

Shown in Fig. 1-2, the New Type of Carbon brush holder in the present embodiment comprises pedestal 1 and is installed on spring 12 in the pedestal 1 that carbon brush 6 is installed in the pedestal 1; Installing rack 3, it is set up on the shell of pedestal 1; Plate body 2, it is installed in the installing rack 3 by an extensile connecting portion 4, and the installation site of corresponding plate body 3 also offers a through hole 11 on the shell, and plate body 2 enters in the pedestal 2 by through hole 11; Include the warning device 5 of audible alarm unit 51, the position of its corresponding plate body 3 is arranged in the mounting groove 13 on pedestal 2 bottom interior wall, and the switch 52 of warning device 5 is over against the bottom 21 of plate body 3.Wherein, the setting position of plate body 2, through hole 11 and warning device 5 etc. should be arranged near on the position of carbon brush 6 afterbodys, be on the afterbody of pedestal 1, whether the carbon piece of surveying carbon brush 6 will be finished, and the initial position of plate body 2 also should be the surface that its bottom rides over carbon brush 6, in case the carbon piece of low carbon brush partly disappears, plate body 2 just can enter into pedestal 1 inside.Pass through foregoing description; can see; after the length reduction of carbon brush 6 arrives to a certain degree; plate body 2 can enter in the pedestal 1 and rely on the extensional process of connecting portion 4 to fall to warning device 5 places; and trigger switch 52, open the audible alarm unit 51 of warning device 5 and report to the police, remind the extraneous carbon brush of noting changing; when traditional function is provided, can also in time remind extraneous attention to change carbon brush, thereby the protection commutator is not damaged.

As shown in Figure 1, above-mentioned connecting portion 4 can be spring, and it can rely on the telescopic action of spring that the plate body 2 that falls is in time resetted.Also can adopt connecting rod, other modes such as chain are implemented.

As shown in Figure 2, above-mentioned warning device 5 can also comprise electric light alarm unit 53, it can also be reported to the police with the form of alarm lamp, particularly have on the carbon brush holder of a plurality of carbon brush holders, the staff can distinguish it is that carbon brush in that carbon brush holder need to be changed by alarm lamp, prevents from changing mistake.

Shown in Fig. 1-2, the bottom 21 of above-mentioned plate body 2 can extend to form protuberance 211 along the thickness direction of plate body 2 to both sides, to enlarge the area of bottom 21, guarantees more firmly trigger switch 53.

Warning device 5 mainly comprises audible alarm unit 51, switch 52 and electric light alarm unit 52, can understand according to prior art, it also should connect power supply, and the formation series loop that the circuit connection can be as known in the art etc. is implemented, and gives unnecessary details no longer one by one at this.

Above-described only is preferred implementation of the present invention, should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
