Description
Technical field
The present invention relates to motors, and in particular to electric motor end cap.
Background technique
Since motor part size is limited, many motors directly built-in can not be installed existing motor, but will be outside driving circuit
It sets on the box body for being mounted on hull outside.The existing general water proof structure grade of mounting structure is IPX3, and it is more to be unable to satisfy client
The exploitation demand of sample premium quality product.Existing this kind of product in the market, it is multiple to there is structure more in driving circuit installation component
It is miscellaneous, the larger problem of occupied space.
Summary of the invention
Technical problem to be solved by the invention is to provide the electric motor end cap that one kind is newly conceived, simple for structure, waterproofness
It can be good.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme: a kind of electric motor end cap, it is characterised in that:
Cover board is installed in the outside wall surface of electric motor end cap, installation is built between the inner wall of the cover board and the outside wall surface of electric motor end cap
The accommodating chamber of driving circuit, the inner wall of cover board and the outside wall surface connecting portion of electric motor end cap seal and cooperate.
A kind of optional scheme, annular groove is formed in the outside wall surface of the electric motor end cap, and the cover board has bottom wall
And the ring wall extended from bottom wall to the outside wall surface direction of electric motor end cap, the front end of the ring wall are matched with annular groove sealing
It closes.
A kind of optional scheme offers outlet hole on the wall body of the ring wall.
A kind of optional scheme, the bottom wall of the cover board and the outside wall surface of electric motor end cap are equipped with the spiral shell of several annular arrays
Follow closely mounting hole.
A kind of optional scheme, the annular groove are the axially outwardly extending by the outer ring position of the outside wall surface of electric motor end cap
Two ring muscle encloses at.
A kind of optional scheme is equipped with several screw mounting holes around the cover board ring wall and ring muscle.
A kind of optional scheme, the front end inner ring side of the ring wall are equipped with the annular slope of cooperation clamping sealing ring.
A kind of optional scheme forms several radiation ribs in the outside wall surface of the cover board.
A kind of optional scheme, the cover board are cylindrical shape, and the annular groove is toroidal cavity.
The present invention also provides the motors for being equipped with aforementioned motor end cap.
The present invention only carries out brief transformation in existing electric motor end cap, increases by a cover board, peace can directly be expanded by constructing
The accommodating chamber of motor driving loop (motor driving loop bodyguard sample is any) is filled, structure is very succinct, and globality is strong.Using this new
Electric motor end cap only carried out in the outside wall surface of the electric motor end cap of electric motor end cap brief without changing existing electric motor cage structure
Transformation has higher freedom degree to the design of cover board, and being able to satisfy client diversified (AC enters power bodyguard sample, and DC enters power bodyguard sample) needs
It asks, directly expands installation motor driving loop, shorten the R&D cycle of motor technology upgrading, and letter is installed for manufacture
Single, strong operability, assembly line upgrades caused by avoiding because of product up-gradation, uses manpower and material resources sparingly.Simultaneously, new motor
The use of end cap configuration collocation waterproof O-ring can satisfy the waterproof requirement of IPX4 or more.In addition for the customer, band driving
The motor in circuit can save motor driving loop exploitation, and then avoid motor oscillating caused by mismatching due to driving circuit
Greatly, the problems such as low efficiency, shorten the R&D cycle of product.Electric motor end cap of the present invention is also convenient for driving circuit subsequent installation or adjustment
Or maintenance, it is not necessarily to integral demounting electric motor end cap.
Detailed description of the invention
Fig. 1 is that electric motor end cap of the present invention applies 1 structural schematic diagram of embodiment (semi-cutaway) on motor；
Fig. 2 is enlarged view at I in Fig. 1；
Fig. 3 is the side view of motor in Fig. 1；
Fig. 4 is the schematic diagram removed after cover board；
Fig. 5 is the deformation implementation structure of embodiment 1.
Specific embodiment
It as shown in Figures 1 to 4, is the motor embodiment 1 equipped with electric motor end cap of the present invention, which includes ontology 1 and peace
Electric motor end cap 2 mounted in ontology one end is equipped with cover board 3, the inner wall of the cover board in the outside wall surface 21 of the electric motor end cap
The accommodating chamber 4 of installation driving circuit 01, the inner wall and electric motor end cap of cover board are built between 31 and the outside wall surface of electric motor end cap
Outside wall surface connecting portion seal cooperation.Annular groove 22 is formed in the outside wall surface 21 of electric motor end cap described in the present embodiment,
Annular groove 22 can be directly recessed in the outside wall surface of electric motor end cap 21, or pass through the outside wall surface 21 by electric motor end cap
The axially outwardly extending two ring muscle 211 in outer ring position surround.The cover board 3 has bottom wall 32 and from bottom wall to electric motor end cap
The ring wall 33 that outside wall surface direction extends, the front end of the ring wall and annular groove sealing cooperate, and select in the present embodiment
Sealing fit form is that sealing ring 5 is set in the annular groove 22, is passed through between the front end of the ring wall and the annular groove
Sealing ring sealing cooperation, the front end inner ring side of ring wall are equipped with the annular slope 332 of cooperation clamping sealing ring.Annular groove is usual
It is designed as circular ring shape, ring wall is then annulus wall, keeps cover board cylindrical, outlet hole 331 is offered on the wall body of the ring wall 33,
Which cabling is more reasonable, is conducive to space layout, and outlet hole 331 is preferably the lower part for being provided with ring wall, has better
Waterproof performance.
In addition as shown in the figure, several radiation ribs 34 are also formed in the outside wall surface of the cover board 3, more safety can
It leans on.
The bottom wall 32 of cover board 3 described in the present embodiment and the outside wall surface 21 of electric motor end cap are equipped with the spiral shell of several annular arrays
Follow closely mounting hole 02.It will be apparent that screw and screw mounting hole should be sealing cooperation, such as by close in order to ensure sealing
Seal washer is realized.The screw used in the present invention includes seal washer.
