Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that, if directional indications (such as up, down, left, right, front, and back … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative positional relationship between the components, the movement situation, and the like in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indications are changed accordingly.

In addition, if there is a description of "first", "second", etc. in an embodiment of the present invention, the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

In some embedded electrical apparatuses provided with a revolving door, a decorative hanging plate is usually installed on the revolving door, so that the overall style of the electrical apparatus is more matched with the surrounding environment, but when the revolving door is opened, the decorative hanging plate interferes with the ground or other structures below the revolving door, and in order to avoid the interference, the prior art provides a technology for enabling the decorative hanging plate to slide relative to the revolving door, namely, the decorative hanging plate slides upwards when the revolving door is opened, so that the lower end of the decorative hanging plate is prevented from colliding with the ground or other structures. However, the sliding structure of the existing decorative hanging plate usually needs to be provided with a complex transmission structure such as a multi-stage gear, and the sliding structure has the disadvantages of high processing difficulty, high production cost, easy blockage by foreign matters and low reliability.

In order to solve the above technical problem, the present invention provides a hinge 500, where the hinge 500 may be implemented such that during the rotating opening process of the door body 200 (corresponding to a rotating door), the panel 300 (corresponding to a decorative hanging plate) on the outer side thereof moves upwards (upwards, i.e. towards the top end of the door body), for example, slides upwards, or translates upwards, and during the rotating closing process of the door body 200, the panel 300 is reset accordingly. The hinge 500 may be applied to furniture, and may also be applied to built-in electric appliances, such as a built-in dishwasher, a built-in oven, and the like.

The present invention also provides an electrical appliance comprising the hinge 500, which in one embodiment is a dishwasher having an interior chamber for loading dishes, a basket disposed in the interior chamber, and the dishes loaded in the basket. In the following embodiments, the structure of the electric appliance and the hinge 500 will be described in detail by taking a dishwasher as an example.

Embedded dish washer imbeds usually and sets up in the cupboard, and its rotation door outside is installed and is covered the anterior decoration link plate of dish washer, the material or the design style etc. of decorating the link plate are usually the same with the door plant of cupboard, make dish washer and cupboard form an pleasing to the eye whole in the outward appearance, play the decorative action. 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. Under some occasions, the length of decorating link plate needs to be designed longer to cover the dish washer more completely, make the outside of dish washer and adjacent cupboard door plant are more unified pleasing to the eye, however this probably leads to the revolving door of dish washer when opening, and the lower extreme of decorating link plate and the cabinet body or ground take place to interfere, lead to the user to use inconveniently.

Therefore, in the embodiment provided by the present invention, referring to fig. 1 to 3, the electrical apparatus includes a main body 100, a door body 200, and the hinge 500 connecting the main body 100 and the door body 200. The main body 100 may be a body of an electrical appliance, for example, a body of an embedded dishwasher, the main body 100 has an inner cavity, the inner cavity has an opening, and the door 200 is openably and closably disposed at the opening. In the present embodiment, as shown in fig. 6 to 11, the door body 200 is rotatably connected to the main body 100 by the hinge 500, and the door body 200 rotates around a first direction, which is a direction in which the rotating shaft 203 extends, and generally, the first direction is a direction parallel to a mounting surface of the main body 100, for example, parallel to the ground. The door 200 has a closed state of rotating to close the main body 100 (specifically, to close the opening), and an open state of rotating to open the main body 100 (specifically, to open the opening). The door body 200 has a fixed end 201 and a rotating end 202 arranged along a second direction, which may be the second direction intersecting the first direction. Here, the fixed end 201 and the rotating end 202 are relative, and the fixed end 201 is close to the hinge 500 and the rotating end is far from the hinge 500. For example, when the electrical equipment is placed on the ground, the bottom end of the door body 200 is a fixed end 201, and the top end is a rotating end 202. The fixed end 201 is rotatably connected to the main body 100 around a rotating shaft 203 extending in a first direction, and the rotating end 202 rotates relative to the fixed end 201, so that the door body 200 is switched between the open state and the closed state. As shown in fig. 6 to 11, in the process of switching the door body 200 from the closed state to the open state, the rotating end 202 has a movable stroke rotating around the fixed end 201 and rotating away from the main body 100. On the contrary, in the process that the door body 200 is switched from the open state to the closed state, the rotating end 202 has a moving stroke rotating around the fixed end 201 and rotating to approach the main body 100.

In this embodiment, the first direction is an extending direction of the rotating shaft 203, the second direction is a moving direction of the panel 300 relative to the door body 200, and the second direction may be substantially parallel to a plane on which an outer side of the door body 200 is located. Specifically, the first direction and the second direction intersect, preferably, the first direction is substantially perpendicular to the second direction, and the actual directions of the first direction and the second direction are not limited. In a preferred embodiment, the first direction may extend substantially along a horizontal direction, and the second direction is substantially parallel to the outer side surface of the door body 200 and substantially perpendicular to the first direction. Taking a dishwasher as an example, the first direction is substantially horizontal, and the second direction is parallel to the outer side surface of the door body 200, is substantially perpendicular to the first direction, and extends in the vertical direction when the door body 200 is in the closed state. Thus, the door body 200 can be turned and opened from top to bottom relative to the main body 100, and the panel 300 moves towards the rotating end 202 relative to the outer side of the door body 200, i.e. moves relative to the door body 200 in the direction away from the hinge 500, so as to avoid the interference and collision between the lower end of the panel 300 and the ground or other structures.

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

The electrical apparatus further includes a panel 300, the panel 300 is movably disposed on one side of the door body 200, and more specifically, the panel 300 is movably disposed on one side of the door body 200 along the second direction, and during a moving stroke of the door body 200 rotating, the panel 300 can move relative to the door body 200 (e.g., to slide relative to the door body 200 substantially parallel to the door body 200). Of course, it is obvious to those skilled in the art that when the door body is opened, i.e. during the moving stroke of the rotating end 202 rotating away from the main body 100, the panel 300 moves relative to the door body 200 in the second direction and away from the fixed end 201. The panel 300 may be a decorative hanging panel or another panel structure that can move relative to the door 200. In this embodiment, since the panel 300 moves from the fixed end 201 to the rotating end 202 along with the opening of the door 200, the interference and collision between the end of the panel 300 close to the fixed end 201 and the surrounding structures, such as the cabinet and the ground, can be avoided. Of course, when the door 200 is changed from the open state to the closed state, the panel 300 can be reset in the reverse direction (the direction from the rotating end 202 to the fixed end 201).

In order to realize the above transmission, in this embodiment, please refer to fig. 1 to fig. 3, the present invention further provides a hinge 500, where the hinge 500 is used to connect the door 200 and the main body 100, so that the door 200 can be rotatably disposed around a rotating shaft 203 extending along a first direction relative to the main body 100, a movable panel 300 is disposed on one side of the door 200, the door 200 has a fixed end 201 and a rotating end 202 disposed in a second direction, and in a moving stroke of the door 200 switching from the closed state to the open state, the rotating end 202 rotates around the fixed end 201 and rotates away from the main body 100. In a moving stroke of the door 200 switching from the open state to the closed state, the rotating end 202 rotates around the fixed end 201 and rotates to approach the main body 100.

Referring to fig. 3, the panel 300 is disposed on one side of the door 200, specifically, on one side of the door 200 opposite to the main body 100, in a process that the door 200 is opened by rotation, the rotating end 202 rotates away from the main body 100, and the panel 300 moves relative to the door 200 along the second direction and a direction away from the fixed end 201. Thus, the panel 300 is opened along with the rotation of the door body 200 from the fixed end 201 to the direction of the rotating end 202, so that the panel 300 can be prevented from being close to one end of the fixed end 201 and the peripheral structure, such as a cabinet body and the ground, and interference and collision occur. On the contrary, in the process of rotating and closing the door 200, the rotating end 202 rotates to approach the main body 100, and the panel 300 moves relative to the door 200 along the second direction and the direction (i.e. the opposite direction) of approaching the fixed end 201 (which is equivalent to the resetting of the panel 300). Therefore, the panel 300 is closed along with the rotation of the door body 200 and moves from the rotating end 202 to the fixed end 201, so that the position of the panel 300 is matched with the peripheral cabinet body of the electrical equipment in the closed state of the door body 200, and the appearance is more uniform and attractive.

Further, the hinge 500 includes a rotation shaft 203, a hinge arm 10, a driving arm 20 and a mounting member 30, and in the present embodiment, specific shapes and sizes of the rotation shaft 203, the hinge arm 10, the driving arm 20 and the mounting member 30 are not limited, for example, the hinge arm 10, the driving arm 20 and the mounting member 30 may have a plate shape, a rod shape and the like. Specifically, the hinge arm 10 is used to rotatably connect the main body 100 and the door body 200, referring to fig. 6 to 11, the hinge arm 10 has a first coupling part 11 for rotatably coupling around the rotation shaft 203, the rotation shaft 203 extends along the first direction, and the position of the rotation shaft 203 may not be limited, and only the hinge arm 10 can rotate relative to the main body 100, for example, the rotation shaft 203 is fixed to the mounting member 30, and the mounting member 30 is provided on the main body 100, the hinge arm 10 is rotatably provided on the rotation shaft 203, that is, the rotation shaft 203 connects the mounting member 30 and the hinge arm 10 (the rotation shaft 203 is fixed to the mounting member 30, and the hinge arm 10 is rotatably connected to the rotation shaft 203, or the rotation shaft 203 is fixed to the hinge arm 10, and the rotation shaft 203 is rotatably connected to the mounting member 30), and further, the driving arm 20 can be disposed between the hinge arm 10 and the mounting member 30 to simplify the structure. The hinge arm 10 further has a first arm 12 and a second arm 13 around the rotation axis 203, the first arm 12 is used for connecting with the door body 200, such as connecting to the fixed end 201, the second arm 13 is used for connecting with the main body 100, and generally, the second arm 13 is elastically connected with the main body 100, i.e. is elastically connected with the main body 100 through a pulling rope and a tension spring. Through the hinge 500, the main body 100 can be rotatably connected with the door body 200, so that the rotating end 202 rotates around the fixed end 201 to approach or separate from the main body 100, and the door body 200 is switched between the closed state and the open state.

The driving arm 20 is used for being rotationally connected with the panel 300, where the rotational connection is opposite, for example, when the door body 200 is opened or closed, the driving arm 20 and the panel 300 can rotate relatively, the driving arm 20 may not move and the panel 300 rotates, or both the driving arm 20 and the panel 300 rotate, and as long as either one can rotate relative to the other, the driving arm 20 and the panel 300 can be regarded as the rotational connection. Specifically, with continuing reference to fig. 1, 2 and 12 to 19, a second guiding mechanism is disposed between the driving arm 20 and the hinge arm 10, and a first guiding mechanism is disposed between the mounting member 30 and the driving arm 20; the first and second guide mechanisms are configured to: in the moving stroke of the rotation of the door body 200, the driving arm 20 is caused to drive the panel 300 to move relative to the door body 200. It can be understood that the moving stroke of the rotation of the door 200 herein includes the stroke of opening the door 200 and the stroke of closing the door 200, in the moving stroke of the rotation of the door 200, the driving arm 20 rotates relative to the panel 300, and the rotation of the driving arm 20 relative to the panel 300 is relative as described above, and the rotation connection can be regarded as the rotation connection as long as any one can rotate relative to the other, and the description is not repeated herein. When the door body 200 is opened, the hinge arm 10 and the driving arm 20 are directly or indirectly connected to the door body 200, the door body 200 can drive the hinge arm 10 and the driving arm 20 to move, and by arranging the first guide mechanism between the mounting member 30 and the driving arm 20 and arranging the second guide mechanism between the driving arm 20 and the hinge arm 10, the first guide mechanism and the second guide mechanism jointly constrain the driving arm 20, so that the driving arm 20 is driven to rotate relative to the panel 300 and the panel 300 is driven to move relative to the door body 200.

Specifically, in the moving stroke of the rotation of the door body 200, the driving arm 20 moves following the rotation of the hinge arm 10, and the first guide mechanism restricts the rotation of the driving arm 20 following the rotation of the hinge arm 10. For example, in the opening stroke, when the hinge arm 10 rotates, the driving arm 20 can be driven to approach the door body 200, and the rotation of the driving arm 20 following the rotation of the hinge arm 10 is limited to be inconsistent with the action amplitude of the driving arm 20 and the hinge arm 10, for example, the driving arm 20 and the hinge arm 10 can rotate relatively, the driving arm 20 can rotate without rotating the hinge arm 10, the rotation amplitude of the driving arm 20 can be smaller than the rotation amplitude of the hinge arm 10, the rotation direction of the driving arm 20 can be different from the rotation direction of the hinge arm 10 (the driving arm 20 rotates reversely relative to the hinge arm 10), the driving arm 20 can be limited to move only in a linear reciprocating manner and the hinge arm 10 rotates, and the like, that, when the hinge arm 10 rotates, a constraint is applied to the driving arm 20, so that when the hinge arm 10 moves following the rotation of the hinge arm 10, the second guiding mechanism is matched, the panel 300 is urged to move relative to the door 200 in a direction away from the hinge 500 when the door is opened, and the panel 300 is urged to move relative to the door 200 in a direction toward the hinge 500 when the door 200 is closed.

Specifically, in the moving stroke of the door body 200, the second guide mechanism makes the driving arm 20 move following the rotation of the hinge arm 10. For example, in the moving stroke of opening the door body, the hinge arm 10 rotates, the driving arm 20 can move towards the door body 200 following the hinge arm 10, and at this time, the driving arm 20 moves towards the direction close to the door body 200 in cooperation with the first guiding mechanism, so as to act on the panel 300. For example, when the door 200 is opened, the first guide mechanism limits the rotation of the driving arm 20, and due to the driving action of the second guide mechanism, the driving arm 20 moves toward the door 200 as a whole, so as to urge the driving arm 20 to move toward the direction away from the hinge, and at this time, the panel 300 rotates relative to the driving arm 20. Therefore, the movement of the panel 300 and the rotation of the door 200 can be linked more smoothly by the second guide mechanism.

Compared with the technical scheme that the panel 300 moves along with the opening or closing of the door body 200 by utilizing the multi-stage gear transmission and other structures in the prior art, the technical scheme provided by the embodiment can realize the linkage between the rotation of the door body 200 and the movement of the panel 300 only through the constraint action among the hinge arms 10, the driving arms 20 and the mounting pieces 30 in the hinge 500, and has the advantages of simple and reliable structure, easy manufacture of the hinge 500 structure, low production cost, simple transmission, difficult occurrence of clamping stagnation and high reliability.

Specifically, with continuing reference to fig. 1 and fig. 12 to 19, the driving arm 20 has a first driving end 21 and a second driving end 22, the first guiding mechanism is disposed between the first driving end 21 and the mounting member 30, and the second driving end 22 is configured to be rotatably connected to the panel 300. That is, the movable stroke of the first driving end 21 of the driving arm 20 is restricted by the first guide mechanism. It can be understood that, since the panel 300 has a moving stroke (e.g. in the second direction) relatively moving with respect to the door body 200, during the moving stroke of the door body 200 being opened by rotation, the movement of the hinge arm 10 causes the driving arm 20 to be stressed to change its position. The first guiding mechanism restricts the hinge arm 10, so as to define a moving track of the driving arm 20, and specifically, for example, in an opening stroke, the first guiding mechanism defines a moving track of the first driving end 21 relative to the main body 100 to be gradually arranged close to the door body 200, so that the second driving end 22 of the driving arm 20 drives the panel 300 to move along the second direction and a direction away from the fixed end 201 along with the rotation of the hinge arm 10.

The specific structure of the first guiding mechanism and the second guiding mechanism is not limited in this embodiment, for example, the first guiding mechanism and the second guiding mechanism may be a sliding pin and a sliding groove which are matched with each other, as long as the constraint on the driving arm 20 can be achieved, the driving arm 20 can be driven to act, so that in a moving stroke in which the rotating end 202 rotates away from the main body 100, through the arrangement of the first guiding mechanism and the second guiding mechanism, a moving track of the first driving end 21 gradually approaches the door body 200, so that in a process in which the driving arm 20 rotates and opens the hinge arm 10, the second driving end 22 can be driven to drive the panel 300 to move relative to the door body 200 along the second direction and a direction away from the fixed end 201. Conversely, in the closing process of the door body 200, the rotating end 202 rotates to be close to the main body 100, and through the arrangement of the first guide mechanism and the second guide mechanism, the driving arm 20 can drive the second driving end 22 to drive the panel 300 to move relative to the door body 200 along the second direction and the direction close to the fixed end 201 in the rotating and closing process of the hinge arm 10, and the moving track of the first driving end 21 gradually leaves away from the door body 200.

It is understood that the first guiding mechanism may be disposed between the driving arm 20 and the main body 100, for example, the sliding pin or the sliding groove is directly molded on the main body 100, and the sliding groove or the sliding pin is correspondingly disposed on the driving arm 20. So set up, make the part of hinge 500 less, occupation space is less, is favorable to the size maximize of electrical equipment.

In the present embodiment, referring to fig. 1, 12 to 19, the first guiding mechanism is provided with a sliding pin or a sliding slot through a mounting member 30 separately provided from the main body 100. The mounting member 30 may be coupled to the body 100 by bolts, welding, or the like. Compared with the technical solution of directly processing on the main body 100, the present embodiment cooperates with the driving arm 20 through the separately provided mounting member 30, and the first guiding mechanism is disposed between the mounting member 30 and the driving arm 20, so that the hinge 500 is easier to manufacture and has low production cost. And the existing electrical equipment structure can be used, mold opening is not required again, development cost is reduced, and it is also beneficial to apply different materials to the hinge 500 and the main body 100.

With continuing reference to fig. 1, 12-19, the mounting member 30 can be fixed to the main body 100 by bolts or other structures. The first guide mechanism includes a first guide pin 41 and a first guide groove 42 respectively disposed on the driving arm 20 and the mounting member 30, specifically, the first guide pin 41 may be disposed on the first driving end 21 of the driving arm 20, the first guide groove 42 may be disposed on the mounting member 30, or the first guide pin 41 may be disposed on the mounting member 30, and the first guide groove 42 may be disposed on the first driving end 21 of the driving arm 20, as long as the first driving end 21 and the mounting member 30 can be engaged with each other. The first guide pin 41 is matched with (inserted into) the first guide groove 42, so that in the moving stroke of the rotating end 202 rotating away from the main body 100, the moving track of the second driving end 22 gradually approaches the door body 200. On the contrary, in the moving stroke of the rotating end 202 rotating to approach the main body 100, the moving track of the second driving end 22 gradually gets away from the door body 200.

Through the above structure, in the process of opening the door body 200 by rotation, when the first driving end 21 of the driving arm 20 is pulled to move in the direction approaching to the door body 200, the first guiding pin 41 and the first guiding groove 42 cooperate to limit the rotation, so as to drive the second driving end 22 of the driving arm 20 to drive the panel 300 to move along the door body 200 in the direction of the rotated end 202. On the contrary, in the process of the door body 200 being rotationally closed, when the first driving end 21 of the driving arm 20 is drawn to move in the direction close to the main body 100, the first guiding pin 41 and the first guiding groove 42 cooperate to limit the rotation, so as to drive the second driving end 22 of the driving arm 20 to drive the panel 300 to move along the door body 200 in the direction of the fixed end 201. In this embodiment, the linkage between the rotation of opening or closing the door 200 and the movement of moving the panel 300 along the door 200 can be realized by the arrangement of the first guide pin 41 and the first guide groove 42, and the structure is simple and reliable, and compared with a complex transmission structure such as a multi-stage gear, the structure is not easy to be jammed, and is easy to manufacture and low in production cost.

Preferably, in this embodiment, with continuing reference to fig. 1, 12 to 19, the first guide pin 41 is disposed at the first driving end 21, the first guide slot 42 is disposed at the mounting member 30, and the first guide slot 42 is bent from the main body 100 toward the door body 200. The specific shape of the first guide groove 42 may be various, and for example, the first guide groove may be a straight line or an arc line, or a combination of the straight line and the arc line, as long as the driving arm 20 can be limited such that the second driving end 22 of the driving arm 20 drives the panel 300 to move along the door body 200 towards the fixed end 201 or the rotating end 202 during the rotation opening or closing process of the hinge arm 10.

As also described above, the first guide groove 42 may be linear (entirely linear, without significant bending), and when the first guide groove 42 is linear, the first guide groove 42 may extend laterally or be inclined from the main body 100 toward the door body 200. Of course, the first guide groove 42, which is curved, may have a lower resistance than a straight shape, and may be designed such that the movement of the panel 200 is not uniform. For example, in the present embodiment, the first guide groove 42 extends in an arc shape, so that the first guide pin 41 slides more smoothly, and the occurrence of the clamping phenomenon is avoided.

In this embodiment, the first guide groove 42 of the mounting member 30 is disposed such that the first driving end 21 of the driving arm 20 is constrained by the first guide groove 42 of the mounting member 30, and the second driving end 22 of the driving arm 20 moves relative to the hinge arm 10 along the second direction, so that during the process (opening stroke) that the rotating shaft 203 of the hinge arm 10 extends along the first direction rotates outwards, the driving arm 20 is driven to drive the panel 300 to move along the second direction and away from the fixed end 201. On the contrary, during the inward rotation (closing stroke) of the rotating shaft 203 of the hinge arm 10 extending along the first direction, the driving arm 20 is driven to drive the panel 300 to move along the second direction and close to the fixed end 210. In this embodiment, the first guide pin 41 and the first guide groove 42 are arranged to realize the linkage between the rotation of opening the door 200 and the movement of the panel 300 along the door 200, and the structure is simple and reliable, and compared with complex transmission structures such as a multi-stage gear, the structure is not easy to be jammed, and is easy to manufacture and low in production cost.

Further, with continued reference to fig. 3 and 5, in some cases, the door 200 may be shielded near the rotating end 202, for example, in a dishwasher installed in a cabinet, a top plate 400 on the upper side of the cabinet may interfere with the upper end of the panel 300. If the panel 300 starts to move upward relative to the door 200 too early in the process of opening the door 200 by rotation, the upper end of the panel 300 may collide with the top plate 400, which may affect the user's use. In this case, it is necessary to design that the panel 300 does not move upward or moves upward to a small extent in the initial stroke of the door 200 being opened by rotation so as to prevent the upper end of the panel 300 from colliding with the top plate 400, and moves toward the top end of the door 200 in the rear stroke of the door 200 being opened so as to prevent the lower end of the panel 300 from colliding with the ground. That is, the moving speed of the panel 300 is not uniform throughout the entire process of the door 200 being opened by rotation, and it is necessary to design the moving speed according to actual conditions. It can be understood that, in other cases, the moving stroke of the panel 300 relative to the door body 200 during the opening process of the door body 200 may be adaptively designed according to actual requirements. In a traditional complex transmission structure, the adaptive design needs a technician to carry out precise design, and high research and development cost is paid. In the embodiment of the present invention, the shape of the first guide groove 42 can be adaptively designed to meet the design requirement of the movement stroke of the panel 300 relative to the door body 200, so that not only various stroke designs can be realized, but also the design is easy to realize, the development cost is low, and the reliability is high.

In an embodiment, referring to fig. 3 and fig. 5, in an electrical appliance, for example, a dishwasher, in order to prevent the upper end of the panel 300 and the top plate 400 from interfering with each other, it may be designed that, in a front-stage stroke of the door 200 being opened by rotation, the position of the panel 300 relative to the door 200 is unchanged, so as to prevent the upper end of the panel 300 from colliding with the top plate 400, and in a rear-stage stroke of the door 200 being opened by rotation, the panel 300 moves relative to the door 200 along the second direction and away from the fixed end 201, so as to prevent the lower end of the panel 300 from colliding with the ground. It is understood that, in the embodiment, the front stroke and the rear stroke refer to two stages arranged in time in the rotational opening stroke of the door body 200. The front section stroke and the rear section stroke can be arranged closely or at intervals. Similarly, in the front stroke of the door 200 being closed by rotation, the panel 300 moves relative to the door 200 along the second direction and in the direction close to the fixed end 201, so as to avoid the lower end of the panel 300 colliding with the ground, and in the rear stroke of the door 200 being closed by rotation, the position of the panel 300 relative to the door 200 is unchanged. Thereby preventing the upper end of the panel 300 from colliding with the top plate 400.

Specifically, with continued reference to fig. 2, the first guide groove 42 has a first section 421 and a second section 422 that are sequentially arranged, where the first section 421 is arranged in an arc shape, and the arc shape means that the first section 421 is arranged in an arc shape with a substantially constant radius, so that during a front section stroke of opening the door body 200, the first guide pin 41 slides in the first section 421, that is, the driving arm 20 is not constrained by the first guide mechanism (is not limited to rotate along with the rotation of the hinge arm 10), the first driving end 21 of the driving arm 20 rotates relative to the rotating shaft 203, and the second driving end 22 does not move or has a small motion relative to the hinge arm 10, so as not to drive the panel 300 to move relative to the door body 200. That is, in the movable front stroke in which the rotating end 202 rotates away from the main body 100, the panel 300 is fixed with respect to the door body 200. In the rear stroke of opening the door body 200, the rotating end 202 continues to rotate away from the main body 100, since the second segment 422 is disposed in an arc shape with a gradually decreasing radius, the driving arm 20 is limited in rotation when moving along with the rotation of the hinge arm 10 (as mentioned above, the rotation limitation is understood to mean that the actuation amplitudes of the driving arm 20 and the hinge arm 10 are not consistent, for example, the driving arm 20 and the hinge arm 10 can rotate relatively, the driving arm 20 does not rotate but the hinge arm 10 rotates, the rotation amplitude of the driving arm 20 around the first guide pin 41 is smaller than the rotation amplitude of the hinge arm 10, the rotation direction of the driving arm 20 around the first guide pin 41 is different from the rotation direction of the hinge arm 10 (i.e. reverse rotation)), therefore, the second driving end 22 drives the panel 300 to move along the second direction and away from the fixed end 201 relative to the door body 200. It can be understood that, due to the structural design of the hinge 500, the panel 300 has an opposite movement stroke during the closing stroke of the door body 200, and the description thereof is omitted.

Through the above structure, at the front stage of the door body 200 being opened by rotation, the position of the panel 300 relative to the door body 200 is unchanged, and at the rear stage of the door body 200 being opened by rotation, the panel 300 moves along the second direction and away from the fixed end 201 relative to the door body 200, so as to avoid collision between the panel 300 and the top plate 400. On the contrary, in the front stage of the door 200 being turned and closed, the panel 300 moves in the second direction and the direction close to the fixed end 201 relative to the door 200, and in the rear stage of the door 200 being turned and closed, the position of the panel 300 relative to the door 200 is not changed. Thereby preventing the panel 300 from colliding with the top plate 400. Therefore, in this embodiment, through the simple structural design of the first guide groove 42, the door body 200 is rotated, the moving stroke of the panel 300 is controlled, the structure is simple, the implementation is easy, the moving speed of the panel 300 is accurately controlled according to the actual situation of the electrical equipment, and the use experience of a user is improved.

In order to further limit the rotation and movement locus of the driving arm 20, so that the movement of the panel 300 is more smoothly linked with the rotation of the door body 200, the driving arm 20 has an intermediate section 23 between the first driving end 21 and the second driving end 22, and the second guide mechanism is disposed between the intermediate section 23 and the hinge arm 10. The intermediate section 23 cooperates with the hinge arm 10 via a second guide mechanism. In this way, by further adding a constraint point between the hinge arm 10 and the driving arm 20, the motion trajectory of the driving arm 20 is more reliably limited, and by adding an acting point of the hinge arm 10 on the driving arm 20 during the rotation process, in the moving stroke of the door body 200 rotating to open the main body 100, the first driving end 21 and the intermediate section 23 approach towards the door body 200, and as the driving force applied to the driving arm 20 is more balanced, the driving arm 20 is driven more smoothly, and the clamping phenomenon is not easy to occur.

Preferably, referring to fig. 1, 2 and 12 to 19, the hinge arm 10 includes a first arm 12 and a second arm 13, the first arm 12 is used for connecting with the door 200, the second arm 13 is used for elastically connecting with the main body 100, and the second guide mechanism is disposed between the second arm 13 and the driving arm 20. First arm 12 and second arm 13 are the contained angle setting, first arm 12 with the junction of second arm 13 forms first connecting portion 11, first connecting portion 11 with pivot 203 is connected or is rotated and is connected.

With reference to fig. 1, fig. 2, and fig. 12 to fig. 19, the second guiding mechanism includes a second guiding pin 51 and a second guiding slot 52, and the second guiding pin 51 is inserted into the second guiding slot 52. In this embodiment, the second guide groove 52 may be provided in the hinge arm 10 and the second guide pin 51 may be provided in the drive arm 20, and in other embodiments, the second guide groove 52 may be provided in the drive arm 20 and the second guide pin 51 may be provided in the hinge arm 10. In this embodiment, the second guide slot 52 is engaged with (inserted into) the second guide pin 51, so that the middle portion of the driving arm 20 is constrained by the hinge arm 10, and thus, by further adding a constraint point between the second arm 13 of the hinge arm 10 and the middle section 23 of the driving arm 20, the motion trajectory of the driving arm 20 is more reliably limited, and the acting point of the hinge arm 10 on the driving arm 20 during the rotation process is increased, and the driving arm 20 is driven more smoothly due to the more balanced driving force applied to the driving arm 20, and the jamming phenomenon is not easy to occur.

In a preferred embodiment, as shown in fig. 1, 2 and 12 to 19, the second guide pin 51 is disposed on the intermediate section 23, the second guide slot 52 is disposed on the second arm 13, and the second guide pin 51 moves in the extending direction of the second guide slot 52. As shown in fig. 2, the second guide groove 52 extends substantially linearly, and may extend along the length direction of the second arm 13 in the second guide groove 52, for example. In this way, in the present embodiment, during the rotation of the hinge arm 10, the middle portion of the driving arm 20 is constrained by the hinge arm 10, the second guiding groove 52 acts on the second guiding pin 51 to drive the driving arm 20 to swing, and the first driving end 21 of the driving arm 20 is constrained by the first guiding groove 42, so that the second driving end 22 of the driving arm 20 drives the panel 300 to move relative to the door body 200. Specifically, during the process of the door 200 being opened by rotation, the driving arm 20 drives the panel 300 to move along the second direction and away from the fixed end 201 relative to the door 200, and during the process of the door 200 being closed by rotation, the driving arm 20 drives the panel 300 to move along the second direction and close to the fixed end 201 relative to the door 200.
