Cover board is firmly fixed on motor gearbox, therefore does not need welding procedure and cover sheet is fixed on motor gearbox
On.
It is according to the present utility model in a first aspect, providing the cover sheet for electric system, including cover plate main body, the lid
There is plate body centre bore and outer periphery edge, the outer periphery to be stretched out along from the peripheral surface of cover plate main body.In the outer of cover plate main body
Multiple ribs are provided on all edges.
Preferably, rib is uniformly distributed circumferentially.
Preferably, rib and cover plate main body are integrally formed.
Embodiment according to the present utility model, rib include cylindrical portion and the spherical portion seamlessly transitted therewith, cylindrical portion from
The peripheral surface of cover plate main body is stretched out.
Preferably, the quantity of rib is 36-72.Correspondingly, rib is circumferentially spaced 5 ° -10 °.
Preferably, cover sheet further includes sealing ring, by moulding injecting glue on cover plate main body.Sealing ring makes motor tooth
Roller box seals.
Second aspect according to the present utility model, provides a kind of electric system, including motor, motor gearbox and above-mentioned
Cover sheet, motor are assembled together with motor gearbox, and cover sheet is fixed on the shell of motor gearbox, motor gear
The output section of case is stretched out from the centre bore of cover plate main body.Rib abuts the inner walls of motor gearbox, and sealing ring is nested in electricity
The lower section of the output section of machine gear-box.
According to the utility model, eliminate at present to the welding procedure for being fixed on cover sheet on motor gearbox
The needs of (such as ultrasonic bonding).Moreover, rib can be directly integrally formed with cover sheet by molding process, without additional
Manufacturing cost.
From the following specifically describes and attached drawing, the other feature and advantage of the utility model will be evident.
Description of the drawings
In the accompanying drawings, for the sake of clarity, the embodiments of the present invention are shown in a simplified manner.Similar attached drawing mark
Note refers to similar part in the accompanying drawings.
Attached drawing is shown：
Fig. 1 is the perspective schematic view of the electric system of the prior art；
Fig. 2 is the schematic, exploded perspective view of the electric system of the utility model embodiment；
Fig. 3 is the perspective schematic view of the cover board of the utility model embodiment；
Fig. 3 A are the enlarged drawings of the Blocked portion in Fig. 3.
Specific implementation mode
The embodiments of the present invention are described referring to Fig. 2-Fig. 3 A.
For ease of description, it is described below and has references to direction shown in the accompanying drawings.It is appreciated that it is practical towards can with it is attached
It is shown in the figure different.
Fig. 3 shows cover sheet 30, including cover plate main body 31 and sealing ring 32.Cover plate main body 31 is recessed annular, tool
There are centre bore 34 and outer periphery edge, the outer periphery is along from the peripheral surface of cover plate main body 31 protrusion (Fig. 3 A best seen from), sealing
Circle 32 is by moulding injecting glue on cover plate main body 31.It is uniformly distributed circumferentially in the outer periphery of cover plate main body along being above formed with
Multiple ribs 33.Cover plate main body 31 and rib 33 can be formed directly by molding process.
Cover sheet 30 shown in Fig. 3 is configured to lower recess.But other constructions are also possible.
If Fig. 3 A are best seen from, rib 33 includes cylindrical portion and spherical portion, they are seamlessly transitted each other, and cylindrical portion is from lid
The peripheral surface of plate body 31 is stretched out.
In embodiment shown in Fig. 3, the quantity of rib 33 is 72.The quantity of rib 33 may be 36, other quantity
It is also possible.
Fig. 2 shows the electric systems 1 of the embodiments of the present invention.Electric system 1 includes motor 10, motor gearbox
20 and cover sheet 30 and socket 50, motor 10 be assembled together with motor gearbox 20, cover sheet 30 is fixed on motor
On the shell of gear-box 20, this is achieved by the following way, and the inner walls of motor gearbox 20 are circumferentially above slotted (not to be marked
Go out), the outer periphery edge of cover plate main body 31 is press fitted into the slit so that rib 33 abuts inner walls.Sealing ring 32 is nested
Lower section in the output section of motor gearbox 20 so that the output section of motor gearbox 20 is stretched out from centre bore 34.It is defeated in this example
It is 21 form of pinion gear to go out portion.
Motor may include that the components such as brush plate component, armature, commutator and motor shaft and motor casing, motor casing pass through connection
Screw 40 and the shell of motor gearbox 20 connect.These components are not the component parts of the utility model, and it is constructed
And with the assembly relation of motor gearbox be well known to those skilled in the art, therefore herein without detailed description.
In some cases, disclosed feature can independently be used with other feature in the present invention.Another party
Face, when necessary, can combine in the present invention disclosed feature to provide various combinations.
Embodiment discussing in a specific embodiment and shown in the accompanying drawings is merely illustrative exemplary embodiment.
For example, in embodiment, glass-frame riser of the cover sheet 30 for the form that the output section of motor gearbox 20 is pinion gear 21,
But cover sheet can be used for other types of glass-frame riser, to protect motor gearbox.
