The interlocking arm 700 has one end connected to the inner moving arm 300 and the other end connected to the swing head 200, so that the interlocking arm 700 and the inner moving arm 300 move in the hinge housing 100 correspondingly by the swing of the swing head 200 in operation.

In a further embodiment, the linkage arm 700 includes: the moving arm 300 is inserted between the left linking arm 710 and the right linking arm 720 to be stably connected.

The principles of the electric mode of operation and the manual mode of operation of the present invention are further explained below.

Electric mode operation principle:

referring to fig. 5-6, the hinge is mounted in an oven having a body 810 and a door 820, in this embodiment. When installed, the hinge housing 100 is confined in the box 810, and the swinging head 200 is confined in the door 820. When the swing head 200 rotates, the door 820 is opened and closed relatively.

In fig. 5, the door 820 is in a closed state, in which the swing head 200 is approximately 90 ° to the hinge housing 100, and this angle is only a rough description, but is not limited to 90 °.

The sliding bracket 400 is located at the right side of the bar groove 110, and the motor bracket 520 is located at the right side of the tank body 120. Meanwhile, as can be seen from fig. 5, under the action of the elastic part 620, the limiting part 610 is located at the upper end of the vertical groove 130 and abuts against the bracket pin 521, and the bracket pin 521 limits the left movement of the motor bracket 520.

Specifically, in the present embodiment, the elastic latch 600 abuts against the bracket pin 521 mounted on the motor bracket 520 for limiting, but does not abut against the motor bracket 520 directly.

But in some implementations it may be that interference is created with the motor bracket 520.

When the door body 820 is opened, the motor 500 operates, the motor output shaft 520 rotates in the forward direction, the sliding support 400 and the motor 500 move relatively when the motor output shaft 520 rotates, and when the motor output shaft rotates in the forward direction, the screw 530 drives the sliding support 400 to move to the left and simultaneously drives the linkage arm 700 to move to the left to drive the swing head 200 to rotate and open, so that the door body 820 is opened.

After the door 820 is opened, as shown in fig. 6, in the power mode, the position of the motor 500 is unchanged, and the sliding bracket 400 moves left on the hinge housing 100 along the bar-shaped groove 110. Comparing fig. 5 and 6, after the door 820 is opened, the length of the screw exposed to the outside is increased because the motor 500 is fixed and the sliding bracket 400 is moved to the left.

When the door is closed, the motor 500 operates, the motor output shaft 520 rotates reversely, the sliding support 400 and the motor 500 move relatively when the motor output shaft 520 rotates, and when the motor output shaft rotates reversely, the screw 530 drives the sliding support 400 to move rightwards and drives the linkage arm 700 to move rightwards at the same time, so that the swing head 200 is driven to rotate and close, and the door body 820 is closed.

During the power-on/off process, the position of the motor 500 is kept unchanged, and the motor 500 is limited by the elastic lock catch 600.

Operating principle of manual mode:

referring to fig. 7-8, the hinge is shown mounted in an oven having a body 810 and a door 820, in this embodiment. When installed, the hinge housing 100 is confined in the box 810, and the swinging head 200 is confined in the door 820. When the swing head 200 rotates, the door 820 is opened and closed relatively.

In fig. 7, the door 820 is in a closed state, the sliding bracket 400 is located on the right side of the bar-shaped groove 110, and the motor bracket 520 is located on the right side of the groove body 120. Meanwhile, as can be seen from fig. 7, under the action of the elastic part 620, the limiting part 610 is located at the upper end of the vertical groove 130 and abuts against the bracket pin 521, and the bracket pin 521 limits the left movement of the motor bracket 520.

In the case that the motor is not operated, the sliding bracket 400 and the motor 500 cannot move relatively to each other, and can move only leftward or rightward synchronously.

When the door body 820 is opened, the door body 820 is manually opened, so that the swing head 200 is driven to rotate, when the swing head 200 rotates, the linkage arm 700 and the inner moving arm 300 are pulled to move left synchronously, and meanwhile, the inner moving arm 300 transmits force to the sliding support 400 and the motor 500, so that the sliding support 400 and the motor 500 move left synchronously. When the motor 500 moves to the left, the limiting force of the elastic lock catch 600 needs to be overcome, the elastic lock catch 600 moves downwards for a certain displacement under the reaction force of the bracket pin 521, the bracket pin 521 is released, the bracket pin 521 moves leftwards around the elastic lock catch 600, and after the bracket pin 521 moves leftwards, the elastic lock catch 600 resets until the door body 820 is completely opened.

When the door body 820 is closed, the door body 820 is manually closed, so that the swing head 200 is driven to rotate, when the swing head 200 rotates, the linkage arm 700 and the inner moving arm 300 are pulled to move rightwards synchronously, and meanwhile, the inner moving arm 300 transmits force to the sliding support 400 and the motor 500, so that the sliding support 400 and the motor 500 move rightwards synchronously. After the door body 820 is manually closed, the motor 500 moves to the right end of the groove body 120, the support pin 521 overcomes the limiting force of the elastic lock catch 600 and moves to the right side of the elastic lock catch 600, and the elastic lock catch 600 limits the support pin 521 again.

During the manual closing/opening, the relative distance between the motor 500 and the sliding bracket 400 is constant, and the motor 500 and the sliding bracket 400 move left/right in synchronization.

In the oven, the oven door is opened up and down, two sides of the oven door are provided with hinges, one hinge can adopt the manual-automatic integrated electric oven door hinge, and the other hinge can adopt a hinge with high bearing and buffering function.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
