Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some examples of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention. Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
The utility model provides an end cover structure can be used to with the casing cooperation to carry out the axle head to the casing and seal and the drainage. For example, for the motor, the end cover and the motor casing are in sealing fit through the seam allowance, and the seam allowance structure can be realized by adopting the prior art, which is not described herein again.
It should be noted that, the driving motor in the prior art includes a casing, a front end cover, a rear end cover, and a stator and a rotor assembly arranged in the casing, and the water inlet of the motor mainly includes two aspects, namely, the accumulated water outside the motor permeates into the motor, and the internal condensed water generated by the temperature change of the motor during operation. For an automobile driving motor, a wire harness of the motor is mainly concentrated at a junction box of a rear end cover, the junction box is limited in sealing performance due to the fact that a plurality of wire harness lead holes are formed in the junction box, therefore, external accumulated water easily enters the junction box, meanwhile, due to the fact that the temperature of the motor is large in change during working, condensed water is easily generated in the junction box, and the accumulated water can cause short circuit of the wire harness in the junction box for a long time. On the other hand, the continuous rotation of the motor spindle can also influence the sealing performance of the shaft extension end of the motor, when the spindle rotates, the temperature of the position of the bearing chamber of the end cover rises, the sealing performance between the bearing and the end cover is influenced, and therefore external accumulated water can easily enter the motor through the shaft hole. The motor among the prior art adopts the outlet of seting up with external intercommunication in the motor bottom for solving the problem of intaking to with the inside water discharge of motor, but this kind of structure is under abominable operating mode, for example motor bubble water, inside outside ponding gets into the motor from the outlet on the contrary easily, to the outside water of motor simultaneously, the water gets into behind the motor discharge again and also can lead to the inside stator and rotor of motor to wet, causes motor trouble.
In view of this, the utility model provides a newfashioned motor end cover structure, including the end cover body, the water storage chamber has been seted up to end cover body and motor casing cooperation installation inside, and the water storage chamber has the inlet opening, and the inlet opening communicates with the interior water drainage chamber (for example terminal box, bearing room etc.) of treating of motor to the motor is treated the ponding of drainage intracavity and is passed through the inlet opening drainage to the storage in the water storage intracavity, utilizes the end cover structure in time to derive the ponding in the motor, avoids ponding to get into inside the motor. This internal water storage chamber of end cover and the ponding in the water storage chamber can form the transmission of cutting off and absorptive effect to the motor noise, effectively reduces the motor noise, simultaneously because water is hot than greatly, the heat of end cover bearing chamber can effectively be absorbed to the water of water storage intracavity storage, cools off the motor to make the motor operation more stable.
