Embodiment
Comprise a strutting piece, flexible tongue and be attached at brush on the described flexible tongue according to rectifier carrier of the present utility model.
Described flexible tongue is designed for brush is forced to and the rectifier position contacting.Described keeper (catch) is designed for described tongue is remained on from the position of its contact position withdrawal, is about to tongue and remains in the installation site, leaves its contact position at this installation site center brush.
When the assembling motor, described keeper is activated by the bar on the motor component (for example reduction gearing shell).Therefore, rectifier carrier does not need special member to activate keeper.Therefore, simplified according to the design and the manufacturing of rectifier carrier of the present utility model.
Described flexible tongue is attached to securely on the brush and with brush and is forced into its contact position.Therefore, described tongue must discharge so that brush is arranged on the contact position from keeper simply.This operation can automatically be carried out when motor is assembled, and simplifies the manufacturing of motor.
The member of foundation rectifier carrier of the present utility model is described with reference to Fig. 2.
Each flexible tongue 16 has the end edge and the free end edge that are attached to strutting piece 11.Tongue 16 is attached to the position of strutting piece and determines in the following manner: when not restricted, tongue 16 places brush 15 and the sub-sheet position contacting of rectifier rectification.Yet tongue 16 has certain elasticity, makes tongue 16 can remain on the retracted position, leaves described contact position to keep brush 15, is about to brush 15 and remains on the installation site.Keeper 17 remains on flexible tongue 16 on this installation site.
When the claw 18 of keeper 17 when tongue 16 is thrown off---as shown in Figure 3, the free end of tongue 16 is shifted to the front portion naturally by the end pivot elastic recoil that is fixed in strutting piece 11 around it.Then, the brush 15 that is attached on the tongue places and the rectifier position contacting.
The stiff end of keeper sheet 17 can be fixed to flexible tongue 16.For example, keeper 17 can be integral with flexible tongue 16, so that the part count of rectifier carrier when making minimizes.Thereby the assembly that includes flexible tongue 16 and keeper sheet 17 has formed a kind of folder.
In addition, flexible tongue 16 can conduct electricity, and for example they can be by the copper coin manufacturing.These tongues 16 can be used as electrical connection then, with by brush being arranged to contact with rectifier and the function of brush power supply being combined and further simplifies according to rectifier carrier of the present utility model.Then, described tongue welds or is adhered to described brush by electric conducting material or adhesive.
The setting on rectifier carrier based on execution mode and different component can have only some tongue 16 to conduct electricity, and other tongue is realized being electrically connected by conventional copper braid then, and perhaps all tongues 16 can conduct electricity.
Fig. 3 has provided by bar 31 and has discharged keeper 17 so that brush is placed the schematic diagram of contact position.Keeper 17 can be at the motor component housing---for example reduction gearing shell---is directly discharged by bar 31 during assembling.Can be provided with the bar of one, for example described bar is molded as a single-piece by the plastics manufacturing and with the reduction gearing housing to reduction gearing housing---for example the reduction gearing of window regulator motor---.
When the reduction gearing housing is assembled into when having comprised on the motor that is installed in the rectifier in the rectifier carrier, the bar 31 that is arranged on the reduction gearing housing activates the keeper 17 that is positioned on the flexible tongue 16.Especially, described bar is designed for along a direction with the surperficial almost parallel of flexible tongue 16 and is pressed in the following manner on the keeper sheet 17: this sheet is pulled away from described flexible tongue 16, until the surface of the claw 18 slippage tongues 16 of keeper.Then, flexible tongue 16 discharges and discharges from all restrictions from keeper 17.Described flexible tongue is got back to its rest position then, and this rest position is chosen to make that brush 15 is on the contact position of rectifier.
One includes according to the electric DC motor of rectifier carrier of the present utility model and can assemble as follows.Figure 4 illustrates the decomposition view of this kind motor.
Make by flexible tongue 16 (it can conduct electricity) is attached on the strutting piece 11 according to rectifier carrier 10 of the present utility model, for example make by flexible tongue 16 directly is attached on the printed circuit board (PCB).Rectifier contact brush 15 is attached on each tongue.The point that flexible tongue 16 is fixed on the strutting piece is selected in the following manner: when unrestricted, tongue 16 with brush 15 place with the rectifier position contacting on.Also all be provided with a keeper (can not in Fig. 4, see) for each tongue 16.Described keeper can form a part of described, described form processing with folder, and an arm of this folder is equipped with an aforesaid claw.By with the fixing flexible tongue of keeper brush being placed on the installation site as illustrated in fig. 2.Then, rectifier carrier 10 is attached to strutting piece 50.
Then, stator 40 and be equipped with the rotor shaft 20 of rectifier 21 to fit together with rectifier carrier 10 by strutting piece 50.Rotor shaft 20 stretches in the stator and stretches in the strutting piece 50, and the strutting piece 11 that is parallel to rectifier carrier extends in the following manner: rectifier 21 is arranged to towards contact brush 15.In addition, the commutator segment 21 of rectifier is connected with the rotor winding electric, and brush 15 is connected to the power supply connector that is used for motor 60 by strutting piece 11.This assembling stage of rotor is not subjected to the obstruction of brush 15, and brush 15 continues to remain on the installation site, promptly from the contact position withdrawal of itself and rectifier.
Be fit in the rectifier carrier in case have the rotor of rectifier, can have discharged described flexible tongue 16, thereby brush 15 has been brought to and the rectifier position contacting.The described release of flexible tongue can be carried out when the assembling of reduction gearing housing 30.As reference Fig. 3 was described, reduction gearing housing 30 can include and be designed for the bar (can not see) that activates described keeper in Fig. 4.Therefore, the release of flexible tongue 16 is automatically carried out by the assembling of decelerating casing, has eliminated brush 15 is arranged to the manual operation that contacts with rectifier 21.In the state that assembling is finished, described bar keeps keeper to make it to leave described flexible tongue, with guarantee described brush remain on the rectifier position contacting on.
Certainly, the utility model is not limited to the execution mode as the example description; Thereby, can revise the fastening means between the shape of flexible tongue 16 and keeper 17 and they and the strutting piece 11, and can not depart from category of the present utility model.Similarly, the utility model is by describing with reference to the reduction gearing housing that includes keeper actuator lever 31.Yet these bars 31 can be arranged on the housing of other motor component based on application of the present utility model, for example are arranged on the housing of motor stator.
