Abstract

The utility model relates to a motor end cover, which aims at solving a series of technical problems that the prior motor end cover has unreasonable structure, causes poor operating mode due to shake when in work, and the like. The motor end cover comprises a casing; the center of the casing is provided with a shaft hole for a motor shaft to pass through; and the casing is provided with a wiring terminal of a power cord or a sheet mounting structure, a carbon brush fixed assembling structure and a protector terminal protective structure. With the design, the motor end cover is favorable for fixed assembly of the wiring terminal, a carbon brush fixed mount, a protector and the like, ensures stable work, no shake, no sparks, and the like of the motor in running and has easy assembly.

Description

Electric motor end cap

Technical field

The utility model relates to a kind of motor spare and accessory parts, especially a kind of end cover structure that is used for the micro-machine of powered vehicle window glass up-down.

Background technology

The motor end cap structure of existing powered vehicle glass pane oscilaltion is very simple, only have and be used for axis hole that motor shaft passes and end cap is fixed on pilot hole on the motor main body such as screw hole etc., binding post wherein, the dependency structure that carbon brush fixed mount etc. matches does not all have unified design, thereby make, the interim when mounted perforate of technical staff is fixed on binding post on the end cap, and fixedly connected with binding post at carbon brush fixed mount one end, and other end major part places the end cap inner space, like this, binding post connects insecure, that does not stop when work rocks, thereby may make the power line that is connected on the binding post come off, cause and open circuit, motor can't be worked.And the carbon brush fixed mount is also owing to rock so that the carbon brush loose contact causes the machine operation instability, thereby influences the lifting of window glass for vehicle.

Summary of the invention

The utility model mainly is to be easy to generate when solving fixing unreasonable, the work of the relevant spare and accessory parts of assembling in the end cap of existing window glass for vehicle drive motors such as binding post, carbon brush fixed mount etc. to rock and cause series of technical such as operating state is bad, so provide a kind of have make the related accessory that is assemblied on the electric motor end cap that electric motor end cap stable, reliable operation is installed.

This electric motor end cap includes housing, has the axis hole that motor shaft passes at the center of housing, has power line binding post or slice mounting structure, carbon brush fixed mount assembly structure and protector terminal safeguard structure on housing; This mounting structure is a pair of sheet hole that is located at housing bottom; This assembly structure comprises slotted eye and fixed leg; The notch that described slotted eye matches for the carbon brush fixed mount with wide shape; This safeguard structure is for having the protector of holding cavity volume, and the bottom of this cavity volume has two through holes, has barrier between two through hole.

Be equipped with a lining in the described axis hole.

Described sheet hole is " recessed " shape hole.

Has the screw hole that the carbon brush fixed mount is installed on the described fixed leg.

Because design has mounting structure, assembly structure and safeguard structure, help the fixedly assembling of binding post, carbon brush fixed mount, protector etc. on the utility model end cap, so that working stability during motor rotation, do not rock, do not produce spark etc.; And the assembled group dressing is easy.

Fig. 3 is the A-A sectional structure schematic diagram of Fig. 2;

Fig. 4 looks schematic diagram in the end of Fig. 2.

Embodiment

Referring to Fig. 1～Fig. 4, electric motor end cap of the present utility model includes housing 1, and this housing 1 matches with motor housing, so that assembling.This housing 1 generally is contained between motor housing 100 and the motor output assembly 200 (shown in Figure 1) by the bolt Connection Card between motor housing 100 and the power of motor output assembly 200; Also can directly be assemblied on the motor housing by bolt etc.The center of this housing 1 has the axis hole 11 that motor shaft passes, so that motor shaft passes and operate as normal; Generally speaking, in this axis hole 11, be equipped with a lining 11`, to guarantee that motor shaft is stable in the running and axis hole is not produced wearing and tearing.On housing 1, have power line binding post mounting structure 12, carbon brush fixed mount assembly structure 13 and protector terminal safeguard structure 14.This mounting structure 12 is for being located at a pair of sheet hole of housing bottom, this sheet hole is for " recessed " shape hole (shown in the figure) or be similar to slot, be used for power line binding post or sheet and pass with exterior line power supply and be connected, and guarantee that binding post or sheet have more stable fixed effect and produce spark etc. to prevent to rock; This a pair of sheet hole generally is in axis hole bilateral symmetry position.This assembly structure 13 comprises slotted eye 131 and fixed leg 132; The notch that described slotted eye 131 matches for the carbon brush fixed mount with wide shape is so that the carbon brush fixed mount inserts and has more stable effect in this notch; Shown in the figure, this notch is surrounded mutually by housing and fixed leg; Have the screw hole 133 that the carbon brush fixed mount is installed on the above-mentioned fixed leg 132, the carbon brush fixed mount can be fixedly mounted on the housing by screw etc.This safeguard structure 14 is for having the protector of holding (not illustrating among the figure) cavity volume, and the bottom of this cavity volume has two through holes 141, has to prevent that the wiring of passing this two through hole is in contact with one another the barrier 142 that produces short circuit owing to rocking between two through hole.

Again referring to Fig. 1, the utility model when mounted, earlier carbon brush fixed mount 30 and power line binding post or sheet 10 are welded into one and insert in the mounting structure on the housing 1, and the relevant protector of assembling etc., its binding post links to each other with circumscripted power line, then, this housing 1 is contained between motor housing 100 and the motor output assembly 200 by the bolt Connection Card between motor housing 100 and the power of motor output assembly 200.
