Abstract

The utility model discloses a rain-proof structure of a motor cover box, which comprises a cover box and a machine shell, wherein a circle of water retaining rib is arranged at the joint of the cover box and the machine shell, a circle of water retaining table top is correspondingly arranged on the machine shell, the water retaining rib on the cover box is matched with the water retaining table top to cover the water retaining table top, the end surface of the water retaining rib on the cover box is tightly abutted against the machine shell for sealing, a water guide groove is arranged on the water retaining table top, the water guide groove inclines downwards and inclines obliquely, and a water outlet is arranged at the edge of the water retaining table top at the tail end of the water guide groove. When rainwater infiltrates, the water retaining rib and the sealing ring can block most of the rainwater. Even if some rainwater is retained in the water guide groove through the water retaining ribs, after water in the groove grows from small water drops, the water flows into the water outlet under the action of gravity and flows out, and the water cannot seep into the motor. The rain-proof cover box adopts the 'sparse' idea, and can realize the rain-proof function even if the water-blocking ribs or the sealing rings on the cover box are damaged and fail.

Description

Rain-proof water structure of motor cover box

Technical Field

The utility model relates to the field of motor structures, in particular to a rain-proof structure of a motor cover box.

Background

As shown in the attached figure 1, the rain-proof structure of the existing motor cover box comprises a cover box 1, a machine shell 2, a sealing groove and a sealing ring 3, wherein the cover box compresses the machine shell to be tightly matched, and a pressing foot of the cover box compresses a sealing ring in the sealing groove correspondingly arranged on the machine shell to realize rain-proof and water-proof sealing.

But the idea of the rain-proof water structure is 'blocking'. When the sealing ring is neglected to be installed or the sealing ring is damaged, the blocking effect is invalid, rainwater enters the control part of the motor, and the motor is damaged.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model designs a rain-proof structure of a motor cover box.

The utility model adopts the following technical scheme:

the utility model provides a rain-proof water structure of motor cover box, includes cover box and casing, is located on the cover box and is provided with round manger plate muscle with the casing junction, corresponds on the casing and is provided with round manger plate mesa, and manger plate muscle and manger plate mesa cooperation cladding manger plate mesa on the cover box, the manger plate muscle terminal surface on the cover box closely supports to lean on the casing sealed, is provided with the guiding gutter on the manger plate mesa, and the guiding gutter slant has a down dip, and the terminal manger plate mesa edge of guiding gutter is provided with the outlet.

Preferably, a sealing groove is formed in the end face of the water retaining rib, a sealing ring is arranged in the sealing groove, and the end face of the water retaining rib on the cover box tightly abuts against the machine shell through the sealing ring for sealing.

Preferably, the cross section of the water chute is U-shaped.

Preferably, a plurality of sealing grooves are formed in the machine shell corresponding to the end faces of the water retaining ribs, sealing rings are arranged in the sealing grooves, and the end faces of the water retaining ribs on the cover box extrude the sealing rings on the machine shell to seal.

The utility model has the beneficial effects that: the cover box is provided with a circle of water retaining ribs at the joint with the shell, the shell is correspondingly provided with a circle of water retaining table top, and the water retaining table top is provided with a water guide groove. When rainwater infiltrates, the water blocking rib and the sealing ring can block most of rainwater. Even if some rainwater is retained in the water guide groove through the water retaining ribs, the water in the groove flows into the water outlet under the action of gravity and flows out of the water outlet without overflowing into the motor after the water in the groove grows from small water drops. The utility model adopts the 'dredging' idea, and the function of rain prevention can be realized even if the water retaining rib or the sealing ring on the cover box is damaged and fails.

Detailed Description

The technical scheme of the utility model is further described in detail by the following specific embodiments in combination with the attached drawings:

example (b): as shown in the attached figures 2-7, the rain-proof structure of the motor cover box comprises a cover box 1 and a machine shell 2, wherein a circle of water retaining ribs 4 are arranged at the joint of the cover box and the machine shell, a circle of water retaining table top 5 is correspondingly arranged on the machine shell, the water retaining ribs on the cover box are matched with the water retaining table top to cover the water retaining table top, the end faces of the water retaining ribs on the cover box tightly abut against the machine shell for sealing, a water guide groove 6 is arranged on the water retaining table top, the water guide groove inclines downwards, and a water outlet 7 is arranged at the edge of the water retaining table top at the tail end of the water guide groove.

The end face of the water retaining rib is provided with a sealing groove, a sealing ring is arranged in the sealing groove, and the end face of the water retaining rib on the cover box tightly abuts against the machine shell through the sealing ring for sealing. The cross section of the water chute is U-shaped.

The rain-proof water structure of the motor cover box is characterized in that a circle of water retaining ribs are arranged at the joint of the cover box and the machine shell, a circle of water retaining table top is correspondingly arranged on the machine shell, and a water guide groove is formed in the water retaining table top. When rainwater infiltrates, the water blocking rib and the sealing ring can block most of rainwater. Even if some rainwater is retained in the water guide groove through the water retaining ribs, the water in the groove flows into the water outlet under the action of gravity and flows out of the water outlet without overflowing into the motor after the water in the groove grows from small water drops. The utility model adopts the 'dredging' idea, and the function of rain prevention can be realized even if the water retaining rib or the sealing ring on the cover box is damaged and fails.

The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the spirit of the utility model as set forth in the claims.
