In some embedded appliances with a revolving door, a decorative hanging plate is usually installed on the revolving door, so that the overall style of the appliance is more matched with the surrounding environment, but this may cause the decorative hanging plate to interfere with the ground or other structures below when the revolving door is opened, in order to avoid such interference, the prior art provides a technology of sliding the decorative hanging plate relative to the revolving door, i.e. the decorative hanging plate slides upwards during the opening process of the revolving door, so as to avoid the collision of the lower end of the decorative hanging plate with the ground or other structures. However, the existing sliding structure of the decorative hanging plate generally needs to be provided with a complex transmission structure such as a multi-stage gear, and has the defects of high processing difficulty, high production cost, easy blockage by foreign matters and low reliability.

In order to solve the above-mentioned problems, the present invention provides a hinge 100, wherein the hinge 100 can realize that the panel 400 (corresponding to the decorative hanging plate) at the outer side moves upward (i.e. toward the top end of the door 300) during the rotation and opening process of the door 300 (corresponding to the rotating door), such as sliding upward, or translating upward, and the panel 400 resets during the rotation and closing process of the door 300. The hinge 100 may be applied to furniture, but also to embedded electrical appliances, such as an embedded dishwasher 1, an embedded oven, etc.

The size of the decorative hanging plate can be designed according to the appearance of the adjacent cabinet so as to meet the requirements of users. In some cases, the length of the decorative hanging plate needs to be designed longer to cover the dishwasher 1 more completely, so that the outer side of the dishwasher 1 and the adjacent cabinet door plate are more unified and attractive, however, this may cause interference between the lower end of the decorative hanging plate and the cabinet body or the ground when the rotating door of the dishwasher 1 is opened, resulting in inconvenient use of the user.

It should be noted that, in the present invention, the description of the directivity is only applicable to the description of the azimuth of the electrical apparatus in the normal use state after the installation is completed, and does not include the direction of the electrical apparatus in the production, assembly, or transportation state. The horizontal direction refers to a direction approximately parallel to a horizontal plane, and the up-down direction refers to a direction approximately parallel to a gravity direction or a direction which forms a certain included angle with the gravity direction and is not mutually perpendicular.

In the technical scheme provided by the invention, the hinge 100 is connected with the door body 300 and the main body 200, one side of the door body 300 is provided with the panel 400, the hinge arm 120 and the driving arm 130 are driven to act in the movable stroke of the door body 300 for rotating and opening the main body 200, the first guide mechanism 150 and the second guide mechanism 170 can convert the rotation of the hinge arm 120 into the movement of the moving member 160, and the moving member 160 is linked with the panel 400, so that the panel 400 moves upwards along with the opening of the door body 300. The hinge 100 provided by the invention has the characteristics of simple and reliable transmission, easy structure manufacture and low production cost.

In addition, the electrical apparatus further includes a main body 200, a door 300, and a panel 400, the main body 200 having an inner cavity; the door 300 is rotatably connected to the main body 200 by the hinge 100 to open or close the inner cavity; the panel 400 is movably disposed at one side of the door 300; the first guide mechanism 150 and the second guide mechanism 170 cooperate to enable the driving arm 130 to move along with the rotation of the hinge arm 120 in a moving stroke of the door body 300 to rotate and open the inner cavity, the first driving end 131 of the driving arm 130 moves along the first guide groove 152 of the first guide mechanism 150 and approaches the door body 300, and the second driving end 132 of the driving arm 130 moves along the second guide groove 172 of the second guide mechanism 170 and drives the moving member 160 to move along a direction away from the hinge 100, so that the panel 400 moves relative to the door body 300 in a direction away from the hinge 100.

In this design, the main body 200 may be a housing structure of an electrical apparatus, or may be a body of an electrical apparatus, specifically, for example, a body of the built-in dishwasher 1. The body 200 is formed with a cavity having an opening, which may be formed at any portion of the body 200, for example, at the top or any side of the body 200. In the following embodiments, the opening is formed at the side of the main body 200, and the opening is disposed forward for convenience of understanding.

The door 300 is connected to the main body 200 and is movably disposed with respect to the opening to open and close the opening during a moving stroke thereof. The door 300 may be movable relative to the main body 200 in a variety of ways, such as translation and/or tilting. In an embodiment, the door 300 has a mounting end and a movable end disposed opposite to each other along a plate surface thereof, the mounting end is rotatably mounted on one side of the opening, and a rotation axis thereof is extended along a length direction of the one side of the opening, so that the movable end can be rotated toward the opening direction to cover the opening and rotated away from the opening to open the opening. Specifically, for example, when the electrical apparatus is installed and placed in the up-down direction, the bottom end of the door 300 forms the installation end, the top end of the door 300 forms the movable end, the bottom end of the door 300 forms the installation end, and the hinge 100 is disposed at the installation end downward. When the opening is disposed forward as described above, the door 300 may be turned in a forward direction, i.e., forward and backward direction, to open the opening, and turned backward to cover the opening.

The panel 400 is movably disposed on one side of the door body 300, and both the panel 400 and the door body 300 are disposed in a substantially plate shape, which corresponds to a stacked arrangement in a thickness direction, that is, a front plate surface of the door body 300 is at least partially stacked with a rear plate surface of the panel 400, and the door body 300 and the panel 400 have a movable stroke substantially translating along the stacked plate surfaces. Specifically, the door body 300 may be configured to translate with respect to the panel 400, but generally, the translation of the panel 400 with respect to the door body 300 is described as an example, and the panel 400 translates along the front panel surface of the door body 300. For ease of understanding, the following defines the moving direction of the panel 400 relative to the door 300 as a first direction.

As one skilled in the art will appreciate, when the door 300 is opened, i.e., during the active stroke in which the active end is rotated away from the opening, the panel 400 moves along the front panel of the door 300 in a direction away from the mounting end; during the movable stroke in which the movable end is rotated to be close to the opening, the panel 400 is moved along the front plate surface of the door 300 toward the direction close to the mounting end. The panel 400 may be a decorative hanging plate, or may be other plate-like structures that can move relative to the door 300. In this embodiment, since the panel 400 moves from the mounting end to the movable end along with the opening of the door 300, interference collision between one end of the panel 400 near the mounting end and the surrounding structure, such as a cabinet, the ground, etc., can be avoided.

In this design, the first guide mechanism 150 and the second guide mechanism 170 are configured to: in the rotation stroke of the door 300, the driving arm 130 is driven to move the panel 400 relative to the door 300.

As described above, it should be understood that the movable stroke of the rotation of the door 300 includes the stroke of opening the door 300 and the stroke of closing the door 300, and the driving arm 130 rotates relative to the panel 400 during the movable stroke of the rotation of the door 300, that is, any driving arm 130 and the panel 400 can be considered as a rotation connection as long as they can rotate relative to each other. When the door 300 is opened, because the hinge arm 120 is directly or indirectly connected to the door 300, the door 300 can drive the hinge arm 120 to move, and by providing the first guide mechanism 150 between the mounting member 140 and the driving arm 130 and providing the second guide mechanism 170 between the driving arm 130 and the moving member 160, the first guide mechanism 150 and the second guide mechanism 170 together act on the driving arm 130, so as to drive the driving arm 130 to rotate relative to the panel 400 and drive the panel 400 to move relative to the door 300.

Specifically, in the movable stroke of the rotation of the door 300, the driving arm 130 moves following the rotation of the hinge arm 120, and the first guide mechanism 150 limits the driving arm 130 to rotate following the rotation of the hinge arm 120. For example, in the opening stroke, since the hinge arm 120 and the driving arm 130 are rotationally connected (e.g. rotationally connected by a pin), the driving arm 130 can be driven to approach the door body 300 when the hinge arm 120 rotates, so that the driving arm 130 can be regarded as following movement, the movement can be regarded as following movement to a certain extent, and the limitation of the driving arm 130 to follow the rotation of the hinge arm 120 can be understood as inconsistent movement amplitude of the driving arm 130 and the hinge arm 120, for example, the driving arm 130 and the hinge arm 120 can relatively rotate, the driving arm 130 can not rotate and the hinge arm 120 can rotate, the rotation amplitude of the driving arm 130 can be smaller than the rotation amplitude of the hinge arm 120, the rotation direction of the driving arm 130 can be different from the rotation direction of the hinge arm 120 (the driving arm 130 is reversed relative to the hinge arm 120), the driving arm 130 can be limited to linearly reciprocate and the hinge arm 120 can rotate, and the like, which is equivalent to, when the hinge arm 120 rotates, a constraint is applied to the driving arm 130 so that the driving arm 130 follows the rotation of the hinge arm 120 moves, for example, the driving arm 130 can relatively rotate to the hinge arm 120, the driving arm 120 can not rotate to the hinge arm 120, the driving arm 120 can rotate to the door body 300, the door body 300 can be moved to the door body 300, and the door body 300 can be moved to the door body 300.

Further, in the rotational stroke of the door 300, the second guide mechanism 170 relatively rotates the moving member 160 and the driving arm 130 to cause the moving member 160 to move following the movement of the driving arm 130. That is, the second guide mechanism 170 serves as a reversing mechanism, and can convert the rotational motion of the hinge arm 120 into the movement of the movable member 160 by the driving arm 130. The function of the second guiding mechanism 170 may be not only represented by the switching between two motion modes of rotation and translation, but also represented by, for example, the switching in terms of motion direction, limitation in terms of motion stroke amount, etc., so that in the stroke of opening the door 300, the whole rotation stroke of the driving arm 130 just drives the panel 400 to move to a set position relative to the door 300; in the closing stroke of the door 300, the whole rotation stroke of the driving arm 130 just drives the panel 400 to move to reset relative to the door 300.

Compared with the prior art that the panel 400 moves along with the opening or closing of the door body 300 by using multi-stage gear transmission and other structures, the technical scheme provided by the embodiment can realize the linkage between the rotation of the door body 300 and the movement of the panel 400 only through the constraint actions of the hinge arm 120, the driving arm 130, the mounting piece 140 and the moving piece 160 in the hinge 100, has simple and reliable structure, is easy to manufacture, has low production cost, is simple to transmit, is not easy to generate clamping stagnation phenomenon, and has high reliability.

In this design, the hinge 100 connects the door 300 and the main body 200 and is disposed closer to the mounting end than the movable end. The hinge 100 connects the panels 400. The hinge 100 can convert the rotation of the door 300 relative to the main body 200 into the translation of the panel 400 relative to the door 300, so that the door opening and closing actions of the door 300 and the translation abdication and reset actions of the panel 400 form linkage, and no additional driving device is required, thereby being beneficial to simplifying the structure and reducing the energy consumption.

In the hinge 100, the rotation shaft 110 may be disposed on a rotation axis of a mounting end of the door 300, and based on this, according to actual needs, the mounting end may be further disposed to be rotatably mounted on the main body 200 through the rotation shaft 110, and the hinge arm 120 may be rotatably mounted on the main body 200 through the rotation shaft 110. Alternatively, the shaft 110 may be spaced from the rotation axis of the mounting end. In general, the position of the hinge arm 120 may not be limited, and it is only necessary to ensure that the hinge arm 120 can rotate relative to the main body 100, for example, the hinge arm 120 is fixed to the mounting member 140, and the mounting member 140 is disposed on the main body 100, and the hinge arm 120 is rotatably disposed on the hinge arm 110, that is, the hinge arm 120 is connected to the mounting member 140 and the hinge arm 110 (the hinge arm 120 is rotatably connected to the hinge arm 110, or the hinge arm 120 is rotatably connected to the mounting member 140),

Specifically, referring to fig. 3 to 4 and 10, in an embodiment, the hinge arm 120 includes a first arm 121, a second arm 122, and a connection portion 125 connecting the first arm 121 and the second arm 122, wherein the first arm 121 is connected to the door 300, the second arm 122 is connected to the main body 200, and the connection portion 125 is connected to the rotating shaft 110.

Based on the above, the first arm 121, the connecting portion 125, and the second arm 122 may be arranged in a collinear extension, such that the hinge arm 120 is substantially in a straight arm shape. However, since the hinge arm 120 is disposed near the mounting end, when the door 300 moves to form a corner with the main body 200, the hinge arm 120 is disposed at the corner, in order to adjust the arm of force of the hinge arm 120, in an embodiment, the first arm 121 and the second arm 122 may be further disposed to form an included angle, and the intersection of the first arm 121 and the second arm 122 forms a connection portion 125, so that the hinge arm 120 is generally disposed in a curved shape, and can be better adapted to the mounting environment of the corner, thereby achieving better force transmission.

The first arm 121 may be fixedly connected to the door 300. The connection mode of the two is not limited, and can be one or more of screw connection fixing, buckle fixing, adhesive fixing and adsorption fixing. Specifically, as shown in fig. 10, a threaded hole may be formed at a position corresponding to the first arm 121 and the door 300, and the threaded holes on the first arm 121 and the door 300 may be sequentially connected by a screw connection member, so as to realize connection and fixation between the first arm 121 and the door 300.

The second arm 122 may be elastically connected to the body 200. Generally, the second arm 122 may be coupled to the body 200 by a resilient structure such as a pull cord and/or a tension spring. Based on this, the second arm 122 may be provided with a hook, and the second arm 122 may be detachably connected with the elastic structure such as the pull rope and/or the tension spring through the hook, so as to be more convenient for disassembly and fixation.

The connecting portion 125 is provided with a shaft hole, a notch may be provided on one side of the shaft hole, and the rotating shaft 110 is in running fit with the shaft hole. The connection portion 125 may further be provided with a reinforcing rib protruding from a peripheral side of the shaft hole, and the reinforcing rib may increase connection strength at the shaft hole.

Further, the driving arm 130 is rotatably connected to the hinge arm 120. Specifically, referring to fig. 3-4 and 11, in one embodiment, the driving arm 130 has a first driving end 131, a second driving end 132, and an intermediate section 133 between the first driving end 131 and the second driving end 132. The first driving end 131 and the second driving end 132 may be disposed opposite to each other, or may be disposed at any angle. The first driving end 131 is disposed closer to the main body 200, and the first guiding mechanism 150 is disposed between the first driving end 131 and the mounting member 140; the second driving end 132 is disposed closer to the door 300, the second guiding mechanism 170 is disposed between the second driving end 132 and the moving member 160, and the middle section 133 is rotatably connected to the hinge arm 120.

As such, the movable stroke of the first driving end 131 is constrained by the first guide mechanism 150. It will be appreciated that since the panel 400 has a movable travel that moves relative to the door 300, the movement of the hinge arms 120 causes a change in position of the drive arms 130 during the rotational opening of the door 300. The first guide mechanism 150 restrains the driving arm 130, so that a rotation track and a rotation stroke amount of the driving arm 130 can be defined. It can be appreciated that, under the constraint of the first guide mechanism 150, the driving arm 130 rotates to a set travel relative to the hinge arm 120, so as to drive the second driving end 132 to generate a position change, where the position change of the second driving end 132 may be a linear track, or an arc track when possible, and the setting of the second guide mechanism 170 is to constrain the linear translation of the moving member 160 along the first direction, so as to achieve the purpose of translating the linkage panel 400 along the first direction through the switching motion of the door 300.

As in the present embodiment, the driving arm 130 rotates following the rotation of the hinge arm 120 in the rotation stroke of the door 300. That is, the hinge arm 120 is rotatably connected with the driving arm 130, and the hinge arm 120 is linked with the driving arm 130 to rotate through the rotation connection therebetween.

Specifically, the driving arm 130 is rotatably mounted on the hinge arm 120 through a rotation connection shaft. The rotation connection shaft may be coaxially disposed with the rotation shaft 110, that is, equivalently, the driving arm 130 rotates around the rotation shaft 110 following the rotation of the hinge arm 120.

Alternatively, as in the present embodiment, the rotational connection of the driving arm 130 is spaced apart from the rotation shaft 110 so that the driving arm 130 revolves around the rotation shaft 110 following the rotation of the hinge arm 120 in the rotational stroke of the door 300. In this way, the driving arm 130 may move along the hinge arm 120 toward the door 300, and the driving arm 130 may approach along the first direction as a whole, so as to further help to drive the moving member 160 to translate along the first direction.

In an embodiment, at least the second driving end 132 of the driving arm 130 approaches toward the door 300 during an active stroke in which the door 300 rotates to open the main body 200. Since the second driving end 132 is connected to the moving member 160 and the second guiding mechanism 170 is connected between the two, when it is ensured that at least the second driving end 132 of the driving arm 130 approaches toward the door 300, that is, the second driving end 132 can move the moving member 160 along the first direction through the second guiding mechanism 170.

The specific structures of the first guide mechanism 150 and the second guide mechanism 170 are not limited in this embodiment, for example, may be a sliding pin and a sliding groove that are matched with each other, so long as the restraint of the driving arm 130 can be realized, the driving arm 130 can be driven to act, so that in the opening stroke of the door body 300, through the arrangement of the first guide mechanism 150 and the second guide mechanism 170, the moving track of the first driving end 131 gradually approaches the door body 300, so that in the rotating and opening process of the hinge arm 120, the driving arm 130 can drive the second driving end 132 to drive the panel 400 to move along the first direction and the direction away from the mounting end relative to the door body 300. Conversely, in the closing stroke of the door 300, the movable end rotates to be close to the main body 200, and by virtue of the arrangement of the first guide mechanism 150 and the second guide mechanism 170, the driving arm 130 can drive the second driving end 132 to drive the panel 400 to move relative to the door 300 along the first direction and the direction close to the mounting end in the process of rotating and closing the hinge arm 120, and the moving track of the first driving end 131 is gradually far away from the direction of the door 300.

It is understood that the first guide mechanism 150 may be disposed between the driving arm 130 and the main body 200, for example, the sliding pin or the sliding groove is directly formed on the main body 200, and the sliding groove or the sliding pin is correspondingly disposed on the driving arm 130. This arrangement results in fewer parts and less space for the hinge 100, which is advantageous for maximizing the size of the electrical device.

The first guide mechanism 150 is provided with a slide pin or slide groove 123 by a mount 140 provided separately from the main body 200. The mounting member 140 may be coupled to the main body 200 by means of bolts, welding, or the like. Compared with the technical solution of directly processing the main body 200, the present embodiment cooperates with the driving arm 130 through the separately provided mounting member 140, and the first guiding mechanism 150 is disposed between the mounting member 140 and the driving arm 130, so that the hinge 100 is easier to manufacture and has low production cost. The existing electrical equipment structure can be used without re-opening the mold, so that the research and development cost is reduced, and the hinge 100 and the main body 200 are also beneficial to different materials.

With continued reference to fig. 1 and 3-5, in particular, the mounting member 140 may be fastened to the main body 200 by a structural connection such as a bolt. The first guide mechanism 150 includes a first guide pin 151 and a first guide groove 152 that are separately disposed on the driving arm 130 and the mounting member 140, specifically, the first guide pin 151 may be disposed on the first driving end 131 of the driving arm 130, the first guide groove 152 may be disposed on the mounting member 140, or the first guide pin 151 may be disposed on the mounting member 140, and the first guide groove 152 may be disposed on the first driving end 131 of the driving arm 130, so long as the first driving end 131 and the mounting member 140 can be matched. The first guide pin 151 is matched (inserted) with the first guide slot 152, so that the moving track of the second driving end 132 gradually approaches the direction of the door 300 in the opening stroke of the door 300. Conversely, in the closing stroke of the door 300, the moving track of the second driving end 132 is gradually far away from the door 300.

With the above arrangement, in the opening stroke of the door 300, the first driving end 131 of the driving arm 130 is driven to move in the direction approaching the door 300, and is also engaged with the first guide pin 151 and the first guide slot 152 to limit rotation, so as to drive the second driving end 132 of the driving arm 130 to drive the moving member 160 to move along the direction of the movable end of the door 300. Conversely, in the closing stroke of the door 300, when the first driving end 131 of the driving arm 130 is pulled to move in the direction approaching to the main body 200, the first guiding pin 151 and the first guiding slot 152 cooperate to limit rotation, so as to drive the second driving end 132 of the driving arm 130 to drive the moving member 160 to move along the direction of the door 300 toward the mounting end. In this embodiment, the first guide pin 151 and the first guide groove 152 are arranged to realize the linkage between the opening or closing rotation of the door 300 and the movement of the panel 400 along the door 300, so that the structure is simple and reliable, and compared with the complex transmission structure such as a multi-stage gear, the structure is not easy to be blocked, and the door is easy to manufacture and has low production cost.

Preferably, in this embodiment, referring to fig. 1 to 6, the first guide pin 151 is disposed at the first driving end 131, the first guide groove 152 is disposed at the mounting member 140, and the first guide groove 152 is curved from the main body 200 toward the door 300. The specific shape of the first guide groove 152 may be various, for example, a straight line shape or an arc shape, or a combination of straight line shape and arc shape, so long as the driving arm 130 is limited, so that the second driving end 132 of the driving arm 130 drives the moving member 160 to move along the door 300 toward the installation end or the movable end during the process of rotating the hinge arm 120 to open or close.

As also described above, the first guide groove 152 may be linear (linear as a whole, without significant bending), and when the first guide groove 152 is linear, the first guide groove 152 may extend laterally or be disposed obliquely from the main body 200 toward the door 300. Of course, the first guide groove 152 provided to be curved may have lower resistance to a certain degree than a straight line shape, and may be designed such that the movement of the panel 400 is non-uniform. For example, in this embodiment, the first guide groove 152 extends in an arc shape, so that the first guide pin 151 slides more smoothly, and the jamming phenomenon is avoided.

In addition, the shape of the first guide groove 152 may be adaptively designed to meet the design requirement of the moving stroke of the panel 400 relative to the door body 300, for example, the installation environment and the door opening mode of different electrical equipment are adapted, the first guide groove 152 is divided into different groove sections, and at least part of the groove sections may be differently arranged in shape and extending direction, so that not only can multiple stroke designs be realized, but also the design is easy to realize, the research and development cost is low, and the reliability is high.

In a similar manner to the above, with continued reference to fig. 1 to 6, the second guiding mechanism 170 includes a second guiding pin 171 and a second guiding slot 172, and the second guiding pin 171 is inserted into the second guiding slot 172. In this embodiment, the second guide groove 172 may be disposed on the moving member 160, and the second guide pin 171 may be disposed on the second driving end 132 of the driving arm 130 or near the second driving end 132, or in other embodiments, the second guide groove 172 may be disposed on the driving arm 130, and the second guide pin 171 may be disposed on the moving member 160. In this embodiment, the second guide groove 172 mates (mates) with the second guide pin 171.

In a further aspect, the second guide groove 172 extends along a stacking direction between the panel 400 and the door 300. That is, the second guide groove 172 is extended in the thickness direction of the panel 400 and the door 300. It will be appreciated that when the second driving end 132 of the driving arm 130 moves toward the door 300 along the movement of the middle section 133, the second driving end 132 may be decomposed into components along the first direction and along the stacking direction, and when the second guiding slot 172 is extended along the stacking direction, the components along the first direction and the components along the stacking direction are separated, and the components along the stacking direction are consumed by the sliding connection of the second guiding pin 171 and the second guiding slot 172, and the components along the first direction are remained to push the moving member 160 to move along the first direction as a whole, so as to push the panel 400 to move along the first direction relative to the door 300.

The moving member 160 may be directly slidably coupled to the door 300, that is, an elongated groove may be provided at the door 300 or at the junction between the door 300 and the panel 400, and the moving member 160 slides along the elongated groove. In this embodiment, referring to fig. 2, 4 and 6, the moving member 160 is slidably connected to the hinge arm 120, so as to enable the panel 400 to move relative to the door 300. It is understood that the first arm 121 of the hinge arm 120 may be fixed relative to the door 300, and when the moving member 160 slides relative to the first arm 121 of the hinge arm 120, that is, the moving member 160 slides relative to the door 300, so that the panel 400 connected to the moving member 160 can translate relative to the door 300. By slidably connecting the moving member 160 with the hinge arm 120, at least the moving member 160 and the hinge arm 120 in the hinge 100 may be pre-assembled to form a whole, which contributes to the compact structure of the hinge 100, and also contributes to the simplification of the assembly operation compared to the case where the first arm 121 and the moving member 160 need to be assembled to the door 300 one by one.

The sliding groove 123 may substantially limit the sliding track of the sliding portion 161, but in order to further increase the sliding accuracy and stability of the sliding portion 161, the first arm 121 may further provide a guiding groove on one side of the sliding groove 123, where the guiding groove corresponds to the sliding groove, and the sliding portion 161 is provided with a sliding protrusion in a protruding manner, and the sliding protrusion is slidably connected with the guiding groove; or conversely, a guiding groove corresponding to the extending direction of the sliding groove 123 is opened on one side of the sliding portion 161, and a sliding protrusion is convexly provided at a position of the sliding groove 123 corresponding to the guiding groove, and the sliding protrusion may be slidingly engaged with the guiding groove.

Since the moving member 160 needs to be directly or indirectly connected to the panel 400, in one embodiment, the first arm 121 is disposed between the door 300 and the panel 400, and a through slot 124 is formed on a side facing the panel 400, and the moving member 160 is connected to the panel 400 at the through slot 124. The escape groove 124 communicates with the chute 123, and the sliding portion 161 of the moving member 160 may at least partially protrude outward from the escape groove 124 and be connected to the panel 400; alternatively, the hinge 100 further includes a connection member 190, and the connection member 190 is disposed through the escape groove 124 and connects the sliding portion 161 and the panel 400.
