[0002] In some embedded appliances with revolving doors, decorative panels are often installed on the revolving doors to make the overall style of the appliance match the surrounding environment. However, this may cause the decorative panels to interfere with the ground or other structures below when the revolving door is opened. To avoid this interference, the prior art provides a technology that allows the decorative panels to slide upwards during the opening of the revolving door.

[0003] Taking dishwashers as an example, built-in dishwashers are typically embedded in cabinets. A decorative panel covering the front of the dishwasher is installed on the outside of its rotating door, creating an aesthetically pleasing whole between the dishwasher and the cabinet, serving a decorative purpose. To accommodate users who wish to install longer decorative panels, the panel needs to slide upwards relative to the dishwasher door during opening to avoid interference between the panel and the floor or cabinet structure. However, existing sliding structures for decorative panels usually require complex transmission mechanisms, which are difficult to manufacture, costly to produce, and prone to jamming by foreign objects, resulting in low reliability.

[0059] The objectives, features, and advantages of this invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0061] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0062] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0063] In some embedded appliances with revolving doors, decorative panels are often installed on the doors to better match the overall style of the appliance with its surroundings. However, this can cause the decorative panels to interfere with the ground or other structures below when the revolving door is opened. To avoid this interference, existing technology provides techniques for sliding the decorative panels relative to the revolving door, allowing the panels to slide upwards during opening to prevent the lower end of the panels from colliding with the ground or other structures. However, existing sliding structures for decorative panels typically require complex transmission mechanisms such as multi-stage gears, which are difficult to manufacture, costly to produce, and prone to jamming by foreign objects, resulting in low reliability.

[0064] To address the aforementioned technical problems, this invention provides a hinge 100. The hinge 100 allows the outer panel 400 (equivalent to a decorative panel) to move upwards (upwards, i.e., towards the top of the door 300) during the rotational opening of the door 300 (equivalent to a revolving door). This upward movement can be achieved through sliding or translating upwards. During the rotational closing of the door 300, the panel 400 returns to its original position. The hinge 100 can be applied to furniture or to built-in electrical appliances, such as built-in dishwashers and built-in ovens.

[0065] The present invention also provides an electrical appliance including the hinge 100. In one embodiment, the electrical appliance is a dishwasher 1, which has an inner cavity for loading tableware, and a dish rack is provided in the inner cavity, in which the tableware is loaded. Please refer to [link to previous document]. Figures 1 to 12In the following embodiments, taking dishwasher 1 as an example, the structure of the electrical device and hinge 100 will be described in detail.

[0066] An embedded dishwasher 1 is typically installed within a cabinet. A decorative panel covering the front of the dishwasher 1 is installed on the outside of its rotating door. The material and design of this decorative panel usually match the cabinet door, creating a visually appealing whole between the dishwasher 1 and the cabinet, serving a decorative purpose. The dimensions of the decorative panel can be designed according to the shape of the adjacent cabinet to meet user needs. In some cases, the decorative panel needs to be designed to be longer to completely cover the dishwasher 1, making the outer side of the dishwasher 1 more uniform and aesthetically pleasing with the adjacent cabinet door. However, this may cause the lower end of the decorative panel to interfere with the cabinet or floor when the dishwasher 1's rotating door is opened, resulting in inconvenience for the user.

[0067] It should be noted that the directional descriptions in this invention apply only to the orientation of the electrical equipment in its normal operating state after installation, and do not include the orientation of the electrical equipment during production, assembly, or transportation. The horizontal direction refers to a direction approximately parallel to the horizontal plane, and the vertical direction refers to a direction approximately parallel to the direction of gravity, or a direction that forms a certain angle with the direction of gravity but is not perpendicular to it.

[0068] Please see Figures 1 to 2 , Figures 7 to 8 The electrical device of the present invention includes a hinge 100, which includes a pivot 110, a hinge arm 120, a drive arm 130, a mounting member 140, and a moving member 160. The hinge arm 120 is disposed on the pivot 110 and is rotatable relative to the main body 200, and is used to connect the door body 300 and the main body 200. The drive arm 130 is rotatably connected to the hinge arm 120. A first guide mechanism 150 is provided between the mounting member 140 and the drive arm 130. The moving member 160 is used to connect the panel 400 and is movable relative to the door body 300. A second guide mechanism 170 is provided between the moving member 160 and the drive arm 130. The first guide mechanism 150 and the second guide mechanism 170 are configured to cause the drive arm 130 to move the panel 400 relative to the door body 300 during the rotation stroke of the door body 300.

[0069] In the technical solution provided by this invention, a hinge 100 connects a door body 300 and a main body 200. A panel 400 is provided on one side of the door body 300. During the rotation of the door body 300 to open the main body 200, the hinge arm 120 and the drive arm 130 are driven to move. The first guide mechanism 150 and the second guide mechanism 170 convert the rotation of the hinge arm 120 into the movement of the moving member 160. The moving member 160 is linked with the panel 400, thereby enabling the panel 400 to move upwards as the door body 300 opens. The hinge 100 provided by this invention features simple and reliable transmission, easy manufacturing, and low production cost.

[0070] In addition, the electrical equipment also includes a main body 200, a door 300, and a panel 400. The main body 200 has an inner cavity. The door 300 is rotatably connected to the main body 200 via the hinge 100 to open or close the inner cavity. The panel 400 is movably disposed on one side of the door 300. The first guide mechanism 150 and the second guide mechanism 170 cooperate so that during the movement of the door 300 to open the inner cavity, the drive arm 130 moves following the rotation of the hinge arm 120. The first drive end 131 of the drive arm 130 moves along the first guide groove 152 of the first guide mechanism 150 and approaches the door 300. The second drive end 132 of the drive arm 130 moves along the second guide groove 172 of the second guide mechanism 170 and drives the moving member 160 to move away from the hinge 100, so that the panel 400 moves relative to the door 300 in a direction away from the hinge 100.

[0071] In this design, the main body 200 can be the housing structure of an electrical device or the body of the electrical device, specifically, for example, the body of an embedded dishwasher 1. The main body 200 has an inner cavity with an opening, which can be formed at any location on the main body 200, such as on the top or any side of the main body 200. For ease of understanding, in the following embodiments, the opening is described as being formed on the side of the main body 200 with the opening facing forward.

[0072] The door 300 is connected to the main body 200 and is movably disposed relative to the opening to open and close the opening during its movement. The door 300 can move relative to the main body 200 in various ways, such as translation and / or flipping. In an embodiment, the door 300 has a mounting end and a movable end disposed opposite to each other along its surface. The mounting end is rotatably mounted on one side of the opening, and its axis of rotation extends along the length of that side of the opening, so that the movable end can rotate toward the opening to close it and can rotate away from the opening to open it. Specifically, for example, when the electrical equipment is installed vertically, the bottom end of the door 300 constitutes the mounting end, the top end of the door 300 constitutes the movable end, and the hinge 100 is disposed lower on the mounting end. When the opening is set facing forward as described above, the flipping direction of the door 300 is also front-to-back, specifically it can be flipped forward to open the opening or flipped backward to close the opening.

[0073] The panel 400 is movably disposed on one side of the door body 300. Since both the panel 400 and the door body 300 are generally plate-shaped, they are essentially stacked along their thickness direction. That is, the front panel of the door body 300 and the rear panel of the panel 400 are at least partially stacked, and the door body 300 and the panel 400 have a travel distance that is approximately translational along the stacked panel surfaces. Specifically, the door body 300 can be configured to translate relative to the panel 400, but generally, the translation of the panel 400 relative to the door body 300 will be used as an example for explanation, and the panel 400 translates along the front panel of the door body 300. For ease of understanding, the direction of movement of the panel 400 relative to the door body 300 is defined below as the first direction.

[0074] For those skilled in the art, when the door 300 is opened, that is, during the movement of the movable end away from the opening, the panel 400 moves along the front surface of the door 300 in a direction away from the mounting end; during the movement of the movable end towards the opening, the panel 400 moves along the front surface of the door 300 towards the mounting end. The panel 400 can be a decorative panel or other plate-like structure that can move relative to the door 300. In this embodiment, since the panel 400 moves from the mounting end to the movable end as the door 300 rotates and opens, interference and collision between the end of the panel 400 near the mounting end and surrounding structures, such as cabinets or the floor, can be avoided.

[0075] In this design, the first guide mechanism 150 and the second guide mechanism 170 are configured to cause the drive arm 130 to move the panel 400 relative to the door body 300 during the rotation stroke of the door body 300.

[0076] As described above, it can be understood that the rotational travel of the door 300 includes both the opening and closing travels. During the rotational travel of the door 300, the drive arm 130 rotates relative to the panel 400. That is, any rotational connection can be considered as long as either the drive arm 130 or the panel 400 can rotate relative to the other. When the door 300 is open, 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. By providing a first guide mechanism 150 between the mounting member 140 and the drive arm 130, and a second guide mechanism 170 between the drive arm 130 and the moving member 160, the first guide mechanism 150 and the second guide mechanism 170 together act on the drive arm 130, thereby causing the drive arm 130 to rotate relative to the panel 400 and causing the panel 400 to move relative to the door 300.

[0077] Specifically, during the rotational stroke of the door 300, the drive arm 130 moves following the rotation of the hinge arm 120, and the first guide mechanism 150 restricts the drive arm 130 from rotating in accordance with the hinge arm 120. For example, during the opening stroke, since the hinge arm 120 and the drive arm 130 are rotatably connected (e.g., rotatably connected by a pin), when the hinge arm 120 rotates, it can drive the drive arm 130 closer to the door 300. This can be considered as the drive arm 130 following the door's movement, and this movement can also be considered as a certain degree of following rotation. Restricting the drive arm 130 from following the hinge arm 120 can be understood as the movement amplitudes of the drive arm 130 and the hinge arm 120 being inconsistent. For example, the drive arm 130 and the hinge arm 120 can rotate relative to each other; this could mean that the drive arm 130 does not rotate while the hinge arm 120 rotates, or that the rotation amplitude of the drive arm 130 is less than that of the hinge arm 120, or it could mean that... The rotation direction of the drive arm 130 is different from that of the hinge arm 120 (the drive arm 130 is reversed relative to the hinge arm 120). Alternatively, the drive arm 130 can be restricted to linear reciprocating motion while the hinge arm 120 rotates. This is equivalent to applying a constraint to the drive arm 130 when the hinge arm 120 rotates, so that when it moves with the rotation of the hinge arm 120, it cooperates with the second guide mechanism 170 to move the drive arm 130 closer to the door body 300. This causes the panel 400 to move away from the hinge 100 relative to the door body 300 when the door body 300 is open, and causes the panel 400 to move towards the hinge 100 relative to the door body 300 when the door body 300 is closed.

[0078] Furthermore, during the rotational stroke of the door 300, the second guide mechanism 170 causes the moving member 160 and the drive arm 130 to rotate relative to each other, so that the moving member 160 moves along with the drive arm 130. In other words, the second guide mechanism 170 acts as a reversing mechanism, converting the rotational motion of the hinge arm 120 into the movement of the moving member 160 via the drive arm 130. The function of the second guide mechanism 170 is not only reflected in the switching between rotational and translational motions, but also in aspects such as switching the direction of movement and limiting the amount of movement, ensuring that during the opening stroke of the door 300, the entire rotational stroke of the drive arm 130 precisely moves the panel 400 relative to the door 300 to a set position; and during the closing stroke of the door 300, the entire rotational stroke of the drive arm 130 precisely moves the panel 400 relative to the door 300 to a reset position.

[0079] Compared to existing technologies that utilize multi-stage gear transmission and other structures to achieve the movement of panel 400 as door 300 opens or closes, the technical solution provided in this embodiment can achieve the linkage between door 300 rotation and panel 400 movement solely through the constraint between hinge arm 120, drive arm 130, mounting component 140, and moving component 160 in hinge 100. The structure is simple and reliable, and the hinge 100 structure is easy to manufacture, has low production cost, simple transmission, is not prone to jamming, and has high reliability.

[0080] In this design, the hinge 100 connects the door body 300 and the main body 200, and is positioned closer to the mounting end than the movable end. The hinge 100 connects to the panel 400. The hinge 100 can convert the rotation of the door body 300 relative to the main body 200 into driving the translation of the panel 400 relative to the door body 300, thereby enabling the opening and closing actions of the door body 300 to be linked with the translation, clearance, and reset actions of the panel 400. This eliminates the need for additional driving mechanisms, contributing to structural simplification and energy saving.

[0081] In the hinge 100, the pivot 110 can be located on the rotation axis of the mounting end of the door body 300. Based on this, according to actual needs, the mounting end can be further configured to be rotatably mounted on the main body 200 via the pivot 110, and the hinge arm 120 can be rotatably mounted on the main body 200 via the pivot 110. Alternatively, the pivot 110 can be spaced apart from the rotation axis of the mounting end. In general, the position of the pivot 110 is not limited, as long as it ensures that the hinge arm 120 can rotate relative to the main body 100. For example, the pivot 110 can be fixed to the mounting member 140, which is mounted on the main body 100, and the hinge arm 120 can be rotatably mounted on the pivot 110. That is, the pivot 110 connects the mounting member 140 and the hinge arm 120 (the pivot 110 is fixed to the mounting member 140, and the hinge arm 120 can be rotatably connected to the pivot 110, or the pivot 110 is fixed to the hinge arm 120, and the pivot 110 can be rotatably connected to the mounting member 140).

[0082] Specifically, please refer to Figures 3 to 4 ,and Figure 10 In one embodiment, the hinge arm 120 includes a first arm 121, a second arm 122, and a connecting portion 125 connecting the first arm 121 and the second arm 122. The first arm 121 is connected to the door body 300, the second arm 122 is connected to the main body 200, and the connecting portion 125 is connected to the pivot 110.

[0083] Based on the above, the first arm 121, the connecting portion 125, and the second arm 122 can be arranged collinearly, so that the hinge arm 120 is generally straight. However, since the hinge arm 120 is located near the mounting end, when the door body 300 moves and forms a corner with the main body 200, the hinge arm 120 is located at the corner. In order to adjust the lever arm of the hinge arm 120, in one embodiment, the first arm 121 and the second arm 122 can be further arranged at an angle, and the intersection of the first arm 121 and the second arm 122 forms a connecting portion 125, so that the hinge arm 120 is generally curved, which can better adapt to the installation environment of the corner and achieve better force transmission.

[0084] The first arm 121 can be fixedly connected to the door body 300. The connection method is not limited and can be one or more of the following: screw fixing, snap-fit ​​fixing, adhesive fixing, and adsorption fixing. Specifically, it can be as follows: Figure 10 As shown, threaded holes are made at the corresponding positions of the first arm 121 and the door body 300, and the threaded holes on the first arm 121 and the door body 300 are connected in sequence by screw connectors to realize the connection and fixation between the first arm 121 and the door body 300.

[0085] The second arm 122 can be elastically connected to the main body 200. Generally, the second arm 122 can be connected to the main body 200 via an elastic structure such as a pull rope and / or a tension spring. Based on this, the second arm 122 can be provided with a hook, through which the second arm 122 is detachably connected to the pull rope and / or the tension spring or other elastic structure, making it easier to assemble, disassemble, and fix.

[0086] A shaft hole is provided at the connecting part 125, and the shaft hole may have a notch on one side, and the rotating shaft 110 is rotatably engaged with the shaft hole. The connecting part 125 may further have reinforcing ribs protruding from the periphery of the shaft hole, and the reinforcing ribs can increase the connection strength at the shaft hole.

[0087] Furthermore, the drive arm 130 is rotatably connected to the hinge arm 120. For details, please refer to... Figures 3 to 4 ,and Figure 11 In one embodiment, the drive arm 130 has a first drive end 131, a second drive end 132, and an intermediate section 133 located between the first drive end 131 and the second drive end 132. The first drive end 131 and the second drive end 132 may be arranged opposite each other or spaced apart at any angle. The first drive end 131 is located closer to the main body 200, and a first guide mechanism 150 is provided between the first drive end 131 and the mounting member 140; the second drive end 132 is located closer to the door body 300, and a second guide mechanism 170 is provided between the second drive end 132 and the moving member 160; the intermediate section 133 is rotatably connected to the hinge arm 120.

[0088] Thus, the travel of the first drive end 131 is constrained by the first guide mechanism 150. It can be understood that, since the panel 400 has a travel relative to the door 300, during the rotational opening of the door 300, the movement of the hinge arm 120 causes a positional change in the force on the drive arm 130. The first guide mechanism 150 constrains the drive arm 130, thus limiting its rotation trajectory and travel. It can be understood that, under the constraint of the first guide mechanism 150, the drive arm 130 rotates relative to the hinge arm 120 to a set travel distance, causing a positional change in the second drive end 132. This positional change may be a linear trajectory or an arc trajectory. The second guide mechanism 170 constrains the linear translation of the moving part 160 along the first direction, achieving the purpose of linking the panel 400 to translate along the first direction through the opening and closing movement of the door 300.

[0089] In this embodiment, during the rotational stroke of the door body 300, the drive arm 130 rotates in tandem with the hinge arm 120. That is, the hinge arm 120 and the drive arm 130 are rotatably connected, and the hinge arm 120 is linked to the drive arm 130 for rotation through the rotatable connection between them.

[0090] Specifically, the drive arm 130 is rotatably mounted on the hinge arm 120 via a rotating connecting shaft. The rotating connecting shaft can be coaxially arranged with the rotating shaft 110, which means that the drive arm 130 rotates around the rotating shaft 110 in accordance with the rotation of the hinge arm 120.

[0091] Alternatively, as in this embodiment, the rotatable connection of the drive arm 130 is spaced apart from the pivot 110, so that during the rotational stroke of the door body 300, the drive arm 130 revolves around the pivot 110 following the rotation of the hinge arm 120. In this way, as the drive arm 130 moves toward the door body 300 following the hinge arm 120, and the drive arm 130 as a whole moves closer along the first direction, it further facilitates driving the moving member 160 to translate along the first direction.

[0092] In one embodiment, during the rotational movement of the door 300 to open the main body 200, at least the second driving end 132 of the drive arm 130 approaches the door 300. Since the second driving end 132 is connected to the moving member 160, and the two are connected by the second guide mechanism 170, ensuring that at least the second driving end 132 of the drive arm 130 approaches the door 300 also enables the second driving end 132 to move the moving member 160 along a first direction via the second guide mechanism 170.

[0093] The specific structure of the first guide mechanism 150 and the second guide mechanism 170 is not limited in this embodiment. For example, they can be sliding pins and sliding grooves that cooperate with each other, as long as they can constrain the drive arm 130 and drive the drive arm 130 to move. During the opening stroke of the door 300, through the setting of the first guide mechanism 150 and the second guide mechanism 170, the movement trajectory of the first drive end 131 gradually approaches the door 300. This allows the drive arm 130 to drive the second drive end 132 to drive the panel 400 to move relative to the door 300 along the first direction and away from the mounting end during the rotation and opening of the hinge arm 120. Conversely, during the closing stroke of the door 300, the movable end rotates closer to the main body 200. Through the arrangement of the first guide mechanism 150 and the second guide mechanism 170, the drive arm 130 can also drive the second drive end 132 to drive the panel 400 to move relative to the door 300 along the first direction and closer to the mounting end during the rotation and closing of the hinge arm 120. The movement trajectory of the first drive end 131 gradually moves away from the direction of the door 300.

[0094] It is understood that the first guide mechanism 150 can be disposed between the drive arm 130 and the main body 200, for example, by directly forming the sliding pin or sliding groove on the main body 200, and correspondingly providing the sliding groove or sliding pin on the drive arm 130. This arrangement results in fewer components for the hinge 100, occupies less space, and is beneficial for maximizing the size of the electrical device.

[0095] The first guide mechanism 150 is equipped with a sliding pin or groove 123 via a mounting component 140 that is separately disposed from the main body 200. The mounting component 140 can be connected to the main body 200 by bolts, welding, or other means. Compared to the technical solution of directly processing on the main body 200, this embodiment uses a separately disposed mounting component 140 to cooperate with the drive arm 130, and the first guide mechanism 150 is located between the mounting component 140 and the drive arm 130, making the hinge 100 easier to manufacture and reducing production costs. Furthermore, it can utilize existing electrical equipment structures without the need for new molds, reducing R&D costs, and is also highly beneficial for using different materials for the hinge 100 and the main body 200.

[0096] Please continue to refer to the following: Figure 1 , Figures 3 to 5Specifically, the mounting component 140 can be fixed to the main body 200 by means of bolts or other structural connections. The first guiding mechanism 150 includes a first guide pin 151 and a first guide groove 152 respectively disposed on the drive arm 130 and the mounting component 140. Specifically, the first guide pin 151 can be disposed on the first drive end 131 of the drive arm 130 and the first guide groove 152 can be disposed on the mounting component 140, or the first guide pin 151 can be disposed on the mounting component 140 and the first guide groove 152 can be disposed on the first drive end 131 of the drive arm 130, as long as the cooperation between the first drive end 131 and the mounting component 140 can be achieved. The first guide pin 151 and the first guide groove 152 cooperate (inserte) so that during the opening stroke of the door 300, the movement trajectory of the second drive end 132 gradually approaches the direction of the door 300. Conversely, during the closing stroke of the door 300, the movement trajectory of the second drive end 132 gradually moves away from the door 300.

[0097] With the above structural arrangement, during the opening stroke of the door 300, when the first driving end 131 of the drive arm 130 is pulled towards the door 300, its rotation is also restricted by the cooperation of the first guide pin 151 and the first guide groove 152, thereby driving the second driving end 132 of the drive arm 130 to drive the moving member 160 to move along the door 300 towards the movable end. Conversely, during the closing stroke of the door 300, when the first driving end 131 of the drive arm 130 is pulled towards the main body 200, its rotation is also restricted by the cooperation of the first guide pin 151 and the first guide groove 152, thereby driving the second driving end 132 of the drive arm 130 to drive the moving member 160 to move along the door 300 towards the mounting end. In this embodiment, the rotational action of the door 300 opening or closing and the action of the panel 400 moving along the door 300 can be linked by the setting of the first guide pin 151 and the first guide groove 152. The structure is simple and reliable. Compared with complex transmission structures such as multi-stage gears, it is not easy to jam and is easy to manufacture with low production cost.

[0098] Preferably, in this embodiment, please continue to refer to... Figures 1 to 6The first guide pin 151 is disposed at the first drive end 131, and the first guide groove 152 is disposed at the mounting member 140. The first guide groove 152 bends from the main body 200 toward the door body 300. The specific shape of the first guide groove 152 can be various, such as a straight line or an arc, or a combination of straight and arc shapes, as long as it can restrict the drive arm 130 so that during the rotation of the hinge arm 120 to open or close, the second drive end 132 of the drive arm 130 drives the moving member 160 to move along the door body 300 toward the mounting end or the movable end.

[0099] As mentioned above, the first guide groove 152 can be straight (straight overall, without significant curvature). When the first guide groove 152 is straight, it can extend laterally or be inclined from the main body 200 toward the door 300. Of course, compared to a straight groove, a curved first guide groove 152 can offer lower resistance to a certain extent, and can be designed to allow the panel 400 to move at a non-uniform speed. For example, in this embodiment, the first guide groove 152 extends in an arc shape to make the sliding of the first guide pin 151 smoother and prevent jamming.

[0100] Furthermore, the design requirements for the movement stroke of the panel 400 relative to the door 300 can be met simply by adapting the shape of the first guide groove 152. For example, it can be adapted to the installation environment and opening method of different electrical appliances. The first guide groove 152 can be divided into different groove segments, and the shape and extension direction of at least some of the groove segments can be set differently. This not only enables multiple stroke designs, but is also easy to implement, with low R&D costs and high reliability.

[0101] Similarly, please continue reading Figures 1 to 6 The second guiding mechanism 170 includes a second guide pin 171 and a second guide groove 172, with the second guide pin 171 inserted into the second guide groove 172. In this embodiment, the second guide groove 172 may be located on the moving member 160, while the second guide pin 171 may be located on or near the second driving end 132 of the driving arm 130. In other embodiments, the second guide groove 172 may be located on the driving arm 130, and the second guide pin 171 may be located on the moving member 160. In this embodiment, the second guide groove 172 and the second guide pin 171 cooperate (interlock).

[0102] In a further embodiment, the second guide groove 172 extends along the stacking direction between the panel 400 and the door 300. That is, the second guide groove 172 extends along the thickness direction of the panel 400 and the door 300. It can be understood that when the second drive end 132 of the drive arm 130 moves towards the door 300 following the movement of the intermediate section 133, it can be decomposed into components along the first direction and along the aforementioned stacking direction. When the second guide groove 172 extends along the stacking direction, it is equivalent to separating the components of the second drive end 132 along the first direction and along the stacking direction, and causing the component along the stacking direction to be consumed by the sliding connection of the second guide pin 171 and the second guide groove 172. The remaining component along the first direction pushes the moving member 160 to move entirely along the first direction, thereby pushing the panel 400 relative to the door 300 to move along the first direction.

[0103] The movable component 160 can be directly slidably connected to the door body 300. That is, an elongated groove can be provided on the door body 300 or at the connection between the door body 300 and the panel 400, and the movable component 160 slides along the elongated groove. In this embodiment, please refer to... Figure 2 , Figure 4 and Figure 6 The movable component 160 is slidably connected to the hinge arm 120 to enable the panel 400 to move relative to the door body 300. It is understood that the first arm 121 of the hinge arm 120 can be fixed relative to the door body 300. When the movable component 160 slides relative to the first arm 121 of the hinge arm 120, it is equivalent to the movable component 160 sliding relative to the door body 300, allowing the panel 400 connected to the movable component 160 to also translate relative to the door body 300. By slidably connecting the movable component 160 to the hinge arm 120, at least the movable component 160 and the hinge arm 120 in the hinge 100 can be pre-installed to form a whole, contributing to the compact structure of the hinge 100. Furthermore, compared to the method of installing the first arm 121 and the movable component 160 to the door body 300 one by one, it simplifies the installation operation.

[0104] Specifically, in one embodiment, the hinge arm 120 includes a first arm 121 for connection with the door body 300. The first arm 121 is provided with a slide groove 123, and the moving member 160 is slidably disposed in the slide groove 123. Please refer to... Figure 10 and Figure 11The second arm 122 of the hinge arm 120 and the connecting portion 125 are both generally plate-shaped, enabling them to overlap with the drive arm 130. The first arm 121 of the hinge arm 120 can be a block structure, with the sliding groove 123 extending along the first direction formed on the block structure; alternatively, the first arm 121 of the hinge arm 120 can be formed by sequentially bending a plate to enclose and define the sliding groove 123. Thus, the sliding groove 123 can be a circumferentially closed hole, allowing the sliding member 160, which is slidably connected to it, to be contained within the closed area during sliding, thus increasing the stability of the installation between the sliding member 160 and the sliding groove 123.

[0105] Accordingly, in one embodiment, the moving member 160 includes a sliding part 161 and a guide part 162 connected to each other. The sliding part 161 is slidably mounted in the slide groove 123, and the guide part 162 extends outward from the opening of the slide groove 123 and is connected to the drive arm 130 through the second guide mechanism 170.

[0106] The sliding part 161 is slidably connected to the slide groove 123 and connected to the panel 400. It can be understood that the sliding part 161 is generally block-shaped, and the external dimensions and shape of the sliding part 161 are adapted to the internal dimensions and shape of the slide groove 123.

[0107] The groove 123 can basically limit the sliding trajectory of the sliding part 161. However, in order to further increase the sliding accuracy and stability of the sliding part 161, the first arm 121 can further open a guide groove on one side of the groove 123 that is consistent with the extension direction of the groove 123. The sliding part 161 has a sliding protrusion corresponding to the guide groove, and the sliding protrusion is slidably connected to the guide groove. Alternatively, the guide groove is opened on one side of the sliding part 161 that is consistent with the extension direction of the groove 123. The groove 123 has a sliding protrusion corresponding to the guide groove, and the sliding protrusion is slidably connected to the guide groove.

[0108] Since the movable member 160 needs to be directly or indirectly connected to the panel 400, in one embodiment, the first arm 121 is used to be disposed between the door body 300 and the panel 400, and a clearance groove 124 is provided on the side facing the panel 400. The movable member 160 is connected to the panel 400 at the clearance groove 124. The clearance groove 124 communicates with the slide groove 123, and the sliding part 161 of the movable member 160 can at least partially protrude outward from the clearance groove 124 and connect with the panel 400; or, the hinge 100 further includes a connector 190, which passes through the clearance groove 124 and connects the sliding part 161 and the panel 400.

[0109] The specific structure of the connector 190 is not limited in this design. In one embodiment, please refer to [reference needed]. Figure 8 The connector 190 may be generally plate-shaped. The connector 190 has a first wall surface connected to the movable member 160 and a second wall surface connected to the panel 400. Depending on the orientation of the movable member 160 relative to the panel 400, the first wall surface and the second wall surface may be arranged opposite each other or at an angle. For example, in this embodiment, the plate segment forming the first wall surface and the plate segment forming the second wall surface of the connector 190 are generally perpendicular to each other.

[0110] The guide portion 162 protrudes outward from the slide groove 123, and as described above, the guide portion 162 is used to connect to the second drive end 132 of the drive arm 130 via the second guide mechanism 170. Specifically, in this embodiment, the guide portion 162 may have the second guide groove 172.

[0111] Furthermore, since the movable component 160 is positioned closer to the mounting end of the door body 300, to increase the smoothness of the movement of the panel 400 relative to the door body 300, please refer to [reference needed]. Figure 7 and Figure 9In one embodiment, the hinge 100 or the electrical device further includes a guide 180, which is disposed between the door body 300 and the panel 400, and is positioned closer to the movable end than the mounting end. The guide 180 includes a guide rail 181 and a guide groove 182, one of which is located on the door body 300, and the other on the panel 400. The guide rail 181 extends along the first direction, and the guide groove 182 is slidably connected to the guide rail 181. Specifically, the guide rail 181 can be protruding from the door body 300. One end of the guide rail 181 extends from the door body 300 toward the panel 400 and then bends and extends along the first direction. The panel 400 has a protrusion facing the door body 300. The protrusion has a guide groove 182 extending through it along the first direction. When the door body 300 is in the closed state, the guide groove 182 can be located on the side of the guide rail 181 near the mounting end. During the opening stroke of the door body 300, the moving member 160 drives the panel 400 to translate toward the movable end, causing the guide groove 182 to pass through the guide rail 181 from the free end of the guide rail 181 and slide relative to the guide rail 181 as the panel 400 translates.

[0112] Furthermore, based on any of the above embodiments, the pivot 110 can connect the hinge arm 120 to the main body 200, or the pivot 110 can connect the hinge arm 120 to the mounting member 140. When the pivot 110 connects the hinge arm 120 and the mounting member 140, the hinge 100 is more independent and easier to manufacture, resulting in lower production costs, by using a separately provided mounting member 140 to cooperate with the hinge arm 120. It also allows the use of existing electrical equipment structures without the need for new molds, reducing R&D costs, and is beneficial for using different materials for the hinge 100 and the main body 200.

[0113] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
