An embodiment of the present utility model provides an electronic control box, referring to fig. 1 to 3, including a box body 10, a cover body 20 and a limiting member 30. The cover 20 is rotatably disposed on the case 10, that is, the cover 20 may rotate with respect to the case 10, but not limited to, about a shaft or about a rotation center.

The limiting member 30 is movably disposed on one of the case 10 and the cover 20, that is, the limiting member 30 may be disposed on the case 10 or on the cover 20.

The limiting member 30 is not fixed but movable, and may be disposed in a specific manner, for example, in a translational manner with respect to the case 10 or the cover 20, or in a rotational manner with respect to the case 10 or the cover 20.

When the cover 20 is in a closed state of being covered on the box body 10, the stopper 30 abuts against the other of the box body 10 and the cover 20 by moving, so as to lock the cover 20 on the box body 10.

An embodiment of the present utility model provides an air conditioner, including the air conditioner outdoor unit according to any embodiment of the present utility model.

The electric control box of the embodiment of the utility model comprises a box body 10, a cover body 20 and a limiting piece 30, wherein the cover body 20 is rotatably arranged on the box body 10. When the cover 20 is in a closed state of covering the case 10, the stopper 30 is moved to abut against the other of the case 10 and the cover 20 to lock the cover 20 to the case 10. Thus, on the one hand, the cover 20 is not directly engaged with the case 10, but can rotate relative to the case 10, so that the cover 20 can be directly rotated to perform maintenance operation inside the case 10 without detaching the cover 20 from the case 10, and the maintenance convenience can be improved. On the other hand, the stopper 30 is movably provided on one of the case 10 and the cover 20, and by moving the stopper 30 to abut against the case 10 or the cover 20, the cover 20 can be restricted from rotating relative to the case 10, so that the connection stability between the cover 20 and the case 10 can be ensured. That is, the case body 10 and the cover body 20 of the electric control case of the present utility model not only can be firmly connected, but also can facilitate the maintenance operation of the user on the inside of the case body 10.

In an embodiment, referring to fig. 1 and 7, the limiting member 30 is rotatably disposed on the case 10, the limiting member 30 has an abutting portion 31, and when the cover 20 is in a closed state, the limiting member 30 rotates to make the abutting portion 31 abut against the cover 20.

Specifically, when the cover 20 is put on the case 10, the abutting portion 31 of the stopper 30 is rotated to a position abutting against the cover 20 by rotating the stopper 30. Thereby, the limit of the rotation of the cover 20 can be realized, so that the cover 20 can be locked on the box body 10, and the cover 20 and the box body 10 can be firmly connected.

The position where the abutting portion 31 abuts against the lid 20 is not limited, and for example, the lid 20 has a connection end 21, the connection end 21 is connected to the case 10, the lid 20 is rotatable relative to the case 10 about the connection end 21 as a rotation axis, and the abutting portion 31 abuts against an end of the lid 20 away from the connection end 21.

In one embodiment, the top side of the box body 10 has an access hole, the limiting member 30 is rotatably disposed on the top surface of the box body 10, when the cover body 20 rotates to cover the access hole, the limiting member 30 rotates to the abutting portion 31 to abut against the top surface of the cover body 20, thereby limiting the rotation of the cover body 20.

In one embodiment, the case 10 includes a top plate having an access hole, the limiting member 30 is rotatably disposed on the bottom surface of the cover 20, and when the cover 20 rotates until the cover is disposed on the access hole, the limiting member 30 is located in the case 10 and rotates until the abutting portion 31 abuts against the bottom surface of the top plate, thereby also limiting the rotation of the cover 20.

In one embodiment, referring to fig. 7, one of the case 10 and the stopper 30 has a shaft hole 10a, and the other of the case 10 and the stopper 30 has a rotation shaft 32, and the rotation shaft 32 extends into the shaft hole 10a.

Specifically, the rotatable positioning of the stopper 30 on the case 10 is achieved by the engagement of the shaft hole 10a. That is, the case 10 may have the shaft hole 10a, the stopper 30 may have the rotation shaft 32, the case 10 may have the rotation shaft 32, and the stopper 30 may have the shaft hole 10a. Thus, the rotation shaft 32 extends into the shaft hole 10a, so that the limiting member 30 can rotate relative to the box body 10.

In an embodiment, referring to fig. 8 and 9, the rotating shaft 32 includes two sub-shafts 321 disposed at intervals along a radial direction, and the extending ends 323 of the two sub-shafts 321 extending into the shaft hole 10a protrude toward a side away from each other along the radial direction to form limiting step surfaces 322 respectively, and the aperture of the shaft hole 10a is smaller than the maximum distance between the outer edges of the two limiting step surfaces 322.

Specifically, one end of the sub-shaft 321 extending into the shaft hole 10a is an extending end 323, and two sub-shafts 321 are disposed at intervals. When the insertion ends 323 of the two sub-shafts 321 are inserted into the shaft hole 10a, the insertion ends 323 are brought close to each other to reduce the outer diameter of the rotation shaft 32, thereby facilitating the insertion of the rotation shaft 32. When the two sub-shafts 321 are clamped into the shaft hole 10a, the two extending ends 323 are separated from each other under the action of elastic force to increase the outer diameter of the rotating shaft 32, so that the limiting step surface 322 abuts against the bottom side area at the shaft hole 10a. Thus, the rotation shaft 32 is prevented from being too loose in the shaft hole 10a, so that the stopper 30 cannot abut against the cover 20. For example, the case 10 has a shaft hole 10a, and the stopper 30 includes a rotation shaft 32, and a stopper step surface 322 abuts against the bottom surface of the region of the case 10 at the shaft hole 10a.

In one embodiment, referring to fig. 9, the rotation shaft 32 includes an insertion end 323 inserted into the shaft hole 10a and a fixed end 324 opposite to the insertion end 323, and the outer diameter of the insertion end 323 is gradually reduced toward a side away from the fixed end 324, whereby the insertion end 323 can be easily inserted into the shaft hole 10a.

In an embodiment, referring to fig. 7, the case 10 has a first limiting portion 11, and the first limiting portion 11 is one of a limiting protrusion and a limiting slot. Specifically, the first limiting portion 11 may be a limiting protrusion or a limiting slot.

Referring to fig. 8 and 9, the limiting member 30 has a second limiting portion 33, the second limiting portion 33 is the other of the limiting protrusion and the limiting slot, and when the limiting member 30 rotates to a position where the limiting protrusion is clamped into the limiting slot, the abutting portion 31 abuts against the cover 20.

Specifically, if the first limiting portion 11 is a limiting protrusion, the second limiting portion 33 is a limiting slot, and if the first limiting portion 11 is a limiting slot, the second limiting portion 33 is a limiting protrusion. That is, the first limiting part 11 and the second limiting part 33 are clamped into the limiting clamping groove through the limiting protrusion to perform the limiting function.

Through the joint cooperation of the first limiting part 11 and the second limiting part 33, the limiting part 30 can be prevented from rotating when the abutting part 31 abuts against the cover body 20, so that the effect of stabilizing the limiting part 30 is achieved.

In an embodiment, referring to fig. 8 and 9, the limiting member 30 has a third limiting portion 34, and the third limiting portion 34 is the other one of the limiting protrusion and the limiting slot, when the limiting member 30 rotates to a position where the limiting protrusion is clamped into the limiting slot, the abutting portion 31 is away from the cover 20, so that the cover 20 can rotate relative to the box 10.

Specifically, if the first limiting portion 11 is a limiting protrusion, the third limiting portion 34 is a limiting slot, and if the first limiting portion 11 is a limiting slot, the third limiting portion 34 is a limiting protrusion. That is, the first limiting portion 11 and the third limiting portion 34 may be in a limiting fit, and the limiting protrusion is also engaged into the limiting slot.

Through the clamping fit of the first limiting part 11 and the third limiting part 34, the limiting part 30 can be prevented from rotating when the abutting part 31 is away from the cover body 20, so that the abutting part 31 is prevented from limiting the cover body 20 to rotate.

The stopper 30 may be provided with only the second stopper portion 33, only the third stopper portion 34, or both the second stopper portion 33 and the third stopper portion 34. In the case where the second limit portion 33 and the third limit portion 34 are provided at the same time, the setting type of the second limit portion 33 and the third limit portion 34 is determined according to the type of the first limit portion 11.

In addition, the shapes of the limiting clamping groove and the limiting bulge are not limited, for example, the cross section of the limiting clamping groove is U-shaped or O-shaped, and the limiting bulge is cylindrical.

Of course, the limiting projection which is snapped into the limiting groove can be rotated out of the limiting groove by the manual rotation of the user, thereby enabling the cover 20 to be rotated by rotating the limiting member 30.

In an embodiment, referring to fig. 8 and 9, at least one side of the limiting slot along the rotation direction of the limiting member 30 is provided with a first guiding surface 30a for guiding the limiting protrusion into the limiting slot.

Specifically, the first guiding surface 30a is a wall surface with guiding function, when the limiting member 30 rotates in a direction that the limiting slot and the limiting protrusion are close to each other, the limiting protrusion and the first guiding surface 30a are relatively displaced, and the limiting protrusion is guided into the limiting slot by the first guiding surface 30a.

In the rotation direction of the limiting member 30, the limiting slot may have a first guiding surface 30a on one side, or may have first guiding surfaces 30a on two opposite sides.

The specific shape of the stopper 30 may be determined according to the actual situation such as the shape of the cover 20, the shape of the case 10, etc.

Illustratively, one side of the top surface of the case 10 has an access opening, the cover 20 is covered at the access opening, and the top surface of the cover 20 is higher than the top surface of the case 10. The stopper 30 is bent to form a rotating portion and an abutting portion 31, and the rotating shaft 32 is disposed at the bottom side of the rotating portion and is inserted into the shaft hole 10a of the case 10.

The electric control box further comprises an upper cover plate which is arranged on one side, far away from the access hole, of the top surface of the box body 10, the upper cover plate is abutted to the second step surface, and the top surface of the upper cover plate is flush with the top surface of the cover body 20, so that the top surface of the electric control box is flat and integral at one height.

For another example, referring to fig. 8, a side of the limiting member 30 facing away from the cover 20 has a force applying protrusion 311. Specifically, the part of the limiting member 30 facing away from the cover 20 protrudes to form a force application protrusion 311, and the force application protrusion 311 can improve the friction between the user and the limiting member 30 when the user rotates the limiting member 30, thereby being convenient for the user to apply force and improving the rotating feel.

Of course, other structures of the electronic control box can be provided with protrusions to play different roles.

For example, referring to fig. 9, one of the cover 20 and the abutting portion 31 has a vibration preventing protrusion 40, and when the abutting portion 31 abuts against the cover 20, the other of the cover 20 and the abutting portion 31 abuts against the vibration preventing protrusion 40. By providing the vibration preventing protrusions 40, abnormal noise due to insufficient contact between the cover 20 and the abutting portion 31 can be prevented from occurring when the air conditioner outdoor unit is operated.
