Embodiment
It is specific below in conjunction with the utility model to make the purpose of this utility model, technical solution and advantage clearer
Technical solutions of the utility model are clearly and completely described in embodiment and corresponding attached drawing.Obviously, described embodiment
Only it is the utility model part of the embodiment, instead of all the embodiments.Based on the embodiment in the utility model, this area
Those of ordinary skill's all other embodiments obtained without making creative work, belong to the utility model
The scope of protection.
It should be noted that term " first " in the specification and claims of the utility model and above-mentioned attached drawing,
" second " etc. is for distinguishing similar object, without for describing specific order or precedence.It should be appreciated that so
The data used can exchange in the appropriate case, can be with except at this so as to the embodiment of the utility model described herein
In diagram or description those beyond order implement.
As shown in Fig. 2,3,4,5, a kind of waterproof cover, for carrying out waterproof for motor 2, which includes：Cylinder 1.Cylinder
The both ends of body 1 are respectively openend 11 and blind end 12, be provided with blind end 12 allow motor 2 motor shaft 21 pass through it is logical
Hole 121, and cylinder 1 can be set on the bearing with end cover room 22 of motor 2 by openend 11, in actual installation, such as Fig. 2
Shown, while cylinder 1 is set on bearing with end cover room 22, the motor shaft 21 stretched out from bearing with end cover room 22 can pass through envelope
Through hole 121 on closed end 12.It is equipped with the side wall of cylinder 1, at the position of openend 11 water in cylinder 1 to be arranged
The discharge opening 13 gone out.It should be noted that the waterproof cover both can be used for stretching end cap motor, casing motor, modeling can be used for
Seal motor etc..When cylinder 1 is set on bearing with end cover room 22, since swelling for openend 11 causes cylinder 1 to be deformed, energy
Enough make discharge opening 13 for the minimum point on the side wall of cylinder 1, and then the water in cylinder 1 can be enable swimmingly to flow to and let out
The mouth of a river 13, and discharged through discharge opening 13.
Further, as shown in Fig. 2,4,5, it is provided with the inner wall of cylinder 1 and axially extends and connect with discharge opening 13
Logical water draining groove 14.In actual installation, extreme lower position that water draining groove 14 can be made to be located in the inner wall circumferential direction of cylinder 1
Place, can so make the water at the last position of inner wall of cylinder 1 can enter water draining groove 14, and flow to by water draining groove 14
Discharge opening 13 is discharged to the outside of the waterproof cover, realizes the water resistance of 360 ° of waterproof cover radial direction, and then can adapt to various
Waterproof requirement under environment.In actual fabrication can by the depth of water draining groove 14 and discharge opening 13 be sized for it is smaller,
To prevent insect from entering waterproof cover, and then it ensure that the safety of motor.
Specifically, as shown in figure 5, the cross sectional shape of water draining groove 14 is square or semicircle or half elliptic；And/or
The both sides of water draining groove 14 are transitted to by smooth surface on the inner wall of cylinder 1.The water of other positions so on the inner wall of cylinder 1
Can smoothly it be flowed into water draining groove 14 by smooth surface, wherein the smooth surface can be the chamfering of section circular arc, but
It is not limited to this.
More preferably, in the direction extended from blind end 12 to openend 11, the bottom surface of water draining groove 14 and the axis of cylinder 1
The distance between gradually increase.That is, when water draining groove 14 is located at its lowest position in the inner wall circumferential direction of cylinder 1,
The bottom surface of water draining groove 14 is tilted down towards the direction of discharge opening 13, can so ensure that the water in water draining groove 14 is smooth
Ground flows to discharge opening 13, and is discharged through discharge opening 13.
As a kind of embodiment, cylinder 1 is interference fitted with bearing with end cover room 22.So when cylinder 1 is set in end cap
When on bearing chamber 22, openend 11 can be swollen, when being provided with water draining groove 14 on the inner wall of cylinder 1, openend 11 it is swollen
Conference causes the side wall of cylinder 1 to deform, and makes water draining groove 14 and horizontal direction there are certain angle, at this time water draining groove
14 can be higher than close to the side of open section close to blind end 12, use discharge opening 13 as positioned at the scheme of the gap of openend 11,
It can be its lowest position that discharge opening 13 is located at water draining groove 14, and then ensure the smooth of the water discharge in water draining groove 14
Property.
As a kind of embodiment, as shown in Fig. 2,4,5, reinforcing rib 15 is provided with the inner wall of cylinder 1, to improve
The intensity of cylinder 1, the cross sectional shape of reinforcing rib can be circular or square, when being not limited to this.When specifically used, cylinder 1
Inner wall be connected to by reinforcing rib 15 on bearing with end cover room 22.Wherein, the quantity of reinforcing rib 15 is two or more, and along cylinder
The circumferential direction of 1 inner wall is uniformly distributed.Further, as shown in FIG., reinforcing rib 15 has the abutment end of face bearing with end cover room 22
Face 151, enables reinforcing rib 15 to be connected to by abutting end face 151 on bearing with end cover room 22, along from openend 11 to closing
The extending direction at end 12, abuts end face 151 and is tilted to the axis direction of cylinder 1.It is set in using such scheme by cylinder 1
During on bearing with end cover room 22, as bearing with end cover room 22 is relative to the movement for abutting end face 151, cylinder 1 can be made
Openend 11 is gradually swollen, while also helps and bearing with end cover room 22 is incorporated into cylinder 1.
As a kind of embodiment, reinforcing rib 15 is integrally formed making with cylinder 1, for example with the mode system of casting
Make.Specifically, the first receiving space 16 close to openend 11 and the second accommodation space close to blind end 12 are included in cylinder 1
17,16 and second accommodation space 17 of first receiving space is cylinder, and is coaxially disposed, and the diameter of first receiving space 16 is big
In the second accommodation space 17, reinforcing rib 15 is arranged on the side wall of first receiving space 16.So when by reinforcing rib 15 and cylinder 1
When being casting together, be conducive to draft, simultaneously because reinforcing rib 15 is arranged on the side wall of first receiving space 16, will not be to
Water on two accommodation spaces, 17 inner wall, which is formed, to be stopped, and then improves the discharge effect of water in the second accommodation space 17.
To realize goal of the invention, on the one hand the utility model, which has, provides a kind of motor, including above example is described
Waterproof cover.
Above example makes the utility model have design rationally, simple in structure, and the water that can make to enter in waterproof cover relaxes
The advantages of freely being rejected to outside waterproof cover, and then improving waterproof effect.
The above description is only the embodiments of the present invention, is not intended to limit the present invention, for this area
Technical staff for, various modifications and changes may be made to the present invention.Where within the spirit and principles of the present invention,
Any modification, equivalent replacement, improvement and so on, should be included within the right of the utility model.
