DETAILED DESCRIPTION OF THE EMBODIMENTS

It should be noted that if there is a directional indication (such as up, down, left, right, front, rear...) in the embodiments of the present disclosure, the directional indication is only used to explain the relative positional relationship, movement, etc. of the components in a certain posture (as shown in the drawings). If the specific posture changes, the directional indication will change accordingly.
In addition, the descriptions associated with, e.g., "first" and "second," in the present disclosure are merely for descriptive purposes, and cannot be understood as indicating or suggesting relative importance or impliedly indicating the number of the indicated technical feature. Therefore, the feature associated with "first" or "second" can expressly or impliedly include at least one such feature. Besides, the meaning of "and/or" appearing in the disclosure includes three parallel scenarios. For example, "A and/or B" includes only A, or only B, or both A and B. Besides, the technical solutions between the various embodiments can be combined with each other, but they must be based on the realization of those of ordinary skill in the art. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that such a combination of technical solutions does not exist, nor is it within the scope of the present disclosure.
In some embedded electrical appliances with revolving doors, decorative hanging boards are usually installed on the revolving doors, so that the overall style of the electrical appliance is more compatible with the surrounding environment. However, this may cause the decorative hanging board to interfere with the ground or other structures below when the revolving door is opened. In order to avoid such interference, the decorative hanging board may slide relative to the revolving door, so that during the opening process of the revolving door, the decorative hanging plate slides upward to avoid the lower end of the decorative hanging board from colliding with the ground or other structures. However, this usually needs to be equipped with a complex transmission structure such as multi-stage gears, which is difficult to process, high in production cost, easily stuck by foreign objects, and has low reliability.
In order to solve the above technical problem, the present disclosure provides a hinge 100, during the rotation and opening process of the door body 300 (equivalent to a revolving door), the hinge 100 can realize that the outer panel 400 (equivalent to the decorative hanging board) moves upward (upward, that is, toward the top of the door body 300), for example, slides upward, or translates upward, and during the rotation and closing process of the door body 300, the panel 400 is reset accordingly. The hinge 100 can be applied to furniture, and can also be applied to the built-in electrical device, such as built-in dishwashers 1, built-in ovens, and the like.
The present disclosure also provides an electrical device including the hinge 100. In an embodiment, the electrical device is a dishwasher 1, the dishwasher 1 has an inner cavity for loading tableware, a basket is provided in the inner cavity, and the tableware is loaded in the basket. As shown in FIG. 1 to FIG. 12, in the following embodiments, a dishwasher 1 is taken as an example to describe the structure of the electrical device and the hinge 100 in detail.
The built-in dishwasher 1 is usually embedded in the cabinet, and a decorative hanging board covering the front of the dishwasher 1 is installed on the outside of the revolving door. The material or design style of the decorative hanging board is usually the same as the door panel of the cabinet, so that the dishwasher 1 and the cabinet form a beautiful whole in appearance and play a decorative role. The size of the decorative hanging board can be designed according to the shape of the adjacent cabinets to meet the needs of users. In some occasions, the length of the decorative hanging board needs to be designed to be longer to cover the dishwasher 1 more completely, such that the outer side of the dishwasher 1 and the adjacent cabinet door panel are more unified and beautiful, but this may cause the lower end of the decorative hanging board to interfere with the cabinet body or the ground when the revolving door of the dishwasher 1 is opened, causing inconvenience to the user.
It should be noted that the description of the orientation in the present disclosure is only applicable to the orientation description of the electrical device in the normal use state after the installation is completed, and does not include the orientation of the electrical device in the state of production, assembly or transportation. The horizontal direction refers to a direction substantially parallel to the horizontal plane, and the up-down direction refers to a direction substantially parallel to the direction of gravity, or a direction that forms a certain angle with the direction of gravity and is not perpendicular to each other.
As shown in FIG. 1 to FIG. 2 and FIG. 7 to FIG. 8, the electrical device of the present disclosure includes a hinge 100. The hinge 100 includes a rotating shaft 110, a hinge arm 120, a drive arm 130, a mounting member 140 and a moving member 160. The hinge arm 120 is provided on the rotating shaft 110 and is rotational relative to the main body 200. The hinge arm 120 is configured 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 connected to the panel 400 and is movable relative to the door body 300, and 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 guide the drive arm 130 to drive the panel 400 to move relative to the door body 300 when the door body 300 is rotated.
In technical solutions of the present disclosure, the hinge 100 connects the door body 300 and the main body 200. A panel 400 is provided on one side of the door body 300. When the door body 300 is rotated to open the main body 200, the hinge arm 120 and the drive arm 130 are driven to rotate, the arrangement of 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 can move upward with the opening of the door body 300. The hinge 100 provided by the present disclosure has the characteristics of simple and reliable transmission, easy manufacture and low production cost.
In addition, the electrical device further includes: a main body 200 having an inner cavity; a door body 300 rotatably connected to the main body 200 through the hinge 100 to open or close the inner cavity; and a panel 400 movably provided on one side of the door body 300. The first guide mechanism 150 matches with the second guide mechanism 170, such that when the door body 300 is rotated to open the inner cavity, the drive arm 130 moves along with 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 body 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 in the direction away from the hinge 100, such that the panel 400 moves relative to the door body 300 in a direction away from the hinge 100.
In the present disclosure, the main body 200 may be a housing structure of an electrical device, or may be a body of the electrical device, for example, the body of the built-in dishwasher 1. The main body 200 is formed with an inner cavity, the inner cavity has an opening, and the opening can be formed in any part of the main body 200, for example, formed on the top or any side of the main body 200. For ease of understanding, in the following embodiments, the opening is formed on the side of the main body 200 and the opening is disposed forward as an example for description.
The door body 300 is connected to the main body 200 and is movably provided relative to the opening, to open and cover the opening during its moving stroke. The door body 300 can move relative to the main body 200 in various ways, such as translation and/or flip. In an embodiment, the door body 300 has an installation end and a moving end which are oppositely arranged along the board surface thereof, the installation end is rotatably mounted on one side of the opening, and the rotation axis of the installation end extends along the length direction of the side of the opening, such that the moving end can be rotated toward the opening to cover the opening, and can be rotated away from the opening to open the opening. For example, when the electrical device is installed and placed in the up-down direction, the bottom end of the door body 300 constitutes the installation end. The top end of the door body 300 constitutes the moving end, the bottom end of the door body 300 constitutes the installation end, and the hinge 100 is disposed at the lower end of the installation end. When the opening is disposed forward as described above, the turning direction of the door body 300 is also the front-rear direction. In some embodiments, the door body 300 may be turned forward to open the opening, and turned backward to cover the opening.
The panel 400 is movably provided on one side of the door body 300. Since both the panel 400 and the door body 300 are generally arranged in a plate shape, the two are equivalent to being stacked along the thickness direction, that is, the front panel surface of the door body 300 and the rear panel surface of the panel 400 are at least partially stacked, and the door body 300 and the panel 400 have movable strokes that are substantially translated along the laminated board surface. In some embodiments, the door body 300 can be set to translate relative to the panel 400. Generally, however, the panel 400 is translated relative to the door body 300 as an example for description, and the panel 400 is translated along the front panel surface of the door body 300. For ease of understanding, the moving direction of the panel 400 relative to the door body 300 is defined as the first direction below.
For those skilled in the art, when the door body 300 is opened, that is, during the moving stroke in which the moving end rotates away from the opening, the panel 400 moves in a direction away from the installation end along the front panel of the door body 300. During the movable stroke in which the moving end rotates close to the opening, the panel 400 moves along the front panel surface of the door body 300 toward the direction close to the installation end. The panel 400 may be a decorative hanging board, or may be other plate-like structures that can move relative to the door body 300. In this embodiment, since the panel 400 moves from the installation end to the moving end as the door body 300 rotates and opens, it is possible to avoid interference and collision between one end of the panel 400 close to the installation end and surrounding structures, such as cabinets, floors, and the like.
In the present disclosure, the first guide mechanism 150 and the second guide mechanism 170 guide the drive arm 130 to drive the panel 400 to move relative to the door body 300 when the door body 300 is rotated.
As described above, it can be understood that, the movement stroke of the door body 300 rotation includes the open of the door body 300 and the closing of the door body 300. When the door body 300 rotates, the drive arm 130 rotates relative to the panel 400, that is, as long as either the drive arm 130 and the panel 400 can rotate relative to the other, it can be regarded as a rotational connection. When the door body 300 is opened, because the hinge arm 120 is directly or indirectly connected to the door body 300, the door body 300 can drive the hinge arm 120 to move. A first guide mechanism 150 is provided between the mounting member 140 and the drive arm 130, and a second guide mechanism 170 is provided between the drive arm 130 and the moving member 160, such that the first guide mechanism 150 and the second guide mechanism 170 act together on the drive arm 130, thereby urging the drive arm 130 to rotate relative to the panel 400 and drive the panel 400 to move relative to the door body 300.
When the door body 300 rotates, the drive arm 130 moves along with the rotation of the hinge arm 120, and the first guide mechanism 150 restricts the drive arm 130 from rotating along with the rotation of the hinge arm 120. For example, during the opening stroke, since the hinge arm 120 is rotatably connected to the drive arm 130 (e.g., rotatably connected through a pin). When the hinge arm 120 rotates, it can drive the drive arm 130 to approach the door body 300, so it is considered that the drive arm 130 moves with it, this movement can also be regarded as following rotation to a certain extent, and restricting the rotation of the drive arm 130 along with the rotation of the hinge arm 120 can be understood as the inconsistency of the movement range of the drive arm 130 and the hinge arm 120. For example, the drive arm 130 and the hinge arm 120 can rotate relative to each other. It may be that the drive arm 130 does not rotate while the hinge arm 120 rotates, or the rotation range of the drive arm 130 is smaller than the rotation range of the hinge arm 120. It is also possible that the rotation direction of the drive arm 130 is different from the rotation direction of the hinge arm 120 (the drive arm 130 rotates in an opposite direction relative to the hinge arm 120), or the drive arm 130 is restricted to reciprocate in a straight line while the hinge arm 120 rotates. It is equivalent to applying a constraint to the drive arm 130 when the hinge arm 120 rotates, so that when the hinge arm 120 moves along with the rotation of the hinge arm 120, it cooperates with the second guide mechanism 170, such that the drive arm 130 approaches the door body 300, when the door body 300 is opened, the panel 400 is urged to move relative to the door body 300 in the direction away from the hinge 100, and when the door body 300 is closed, the panel 400 is urged to move relative to the door body 300 in the direction of the hinge 100.
Besides, when the door body 300 rotates, the second guide mechanism 170 makes the moving member 160 and the drive arm 130 rotate relative to each other, to drive the moving member 160 to move along with the movement of the drive arm 130. That is to say, the second guide mechanism 170 acts as a reversing mechanism, which can convert the rotational movement of the hinge arm 120 into the movement of the moving member 160 through the drive arm 130. The function of the second guide mechanism 170 can be embodied not only in the switching between the two motion forms of rotation and translation, but also in the switching of the direction of movement, the limitation of the amount of movement, etc., such that when the door body 300 is opened, the entire rotation stroke of the drive arm 130 just drives the panel 400 to move to the set position relative to the door body 300. When the door body 300 is closed, the entire rotation stroke of the drive arm 130 just drives the panel 400 to move to the reset position relative to the door body 300.
Compared with the technical solution in the prior art in which the panel 400 moves with the opening or closing of the door body 300 by using structures such as multi-stage gear transmission, the technical solution provided in this embodiment can be achieved only through the restraint between the hinge arm 120, the drive arm 130, the mounting member 140 and the moving member 160 in the hinge 100. The linkage between the rotation of the door body 300 and the movement of the panel 400 can be realized, the structure of the hinge 100 is simple and reliable, and the structure of the hinge 100 is easy to manufacture, the production cost is low, the transmission is simple, the jamming phenomenon is not easy to occur, and the reliability is high.
In the present disclosure, the hinge 100 connects the door body 300 and the main body 200, and is disposed closer to the installation end than the moving end. The hinge 100 connects the panel 400. The hinge 100 can convert the rotation of the door body 300 relative to the main body 200 into driving the panel 400 to translate relative to the door body 300, such that the door opening and closing actions of the door body 300 form a linkage with the translational relocation and reset actions of the panel 400, and no additional driving device is required, which is helpful for simplifying the structure and reducing energy consumption.
In the hinge 100, the rotating shaft 110 may be provided on the rotation axis of the installation end of the door body 300. Based on this, according to actual needs, the installation end can be further arranged to be rotated and mounted on the main body 200 through the rotating shaft 110. In addition, the hinge arm 120 is rotatably mounted on the main body 200 through the rotating shaft 110. In some embodiments, the rotating shaft 110 may be spaced apart from the rotation axis of the installation end. In general, the position of the rotating shaft 110 may not be limited, as long as the hinge arm 120 can be rotated relative to the main body 100. For example, the rotating shaft 110 is fixed on the mounting member 140, the mounting member 140 is disposed on the main body 100, and the hinge arm 120 is rotatably disposed on the rotating shaft 110. That is, the rotating shaft 110 connects the mounting member 140 and the hinge arm 120 (the rotating shaft 110 is fixed on the mounting member 140, and the hinge arm 120 is rotatably connected to the rotating shaft 110, or the rotating shaft 110 is fixed on the hinge arm 120, and the rotating shaft 110 is rotatably connected to the mounting member 140).
As shown in FIG. 3 to FIG. 4 and FIG. 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. The first arm 121 is connected to the door body 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 connection portion 125 and the second arm 122 can be arranged to extend in line, so that the hinge arm 120 is generally in the shape of a straight arm. However, since the hinge arm 120 is disposed near the installation end, when the door body 300 moves to form a corner with the main body 200, the hinge arm 120 is provided at the corner. In order to adjust the moment arm of the hinge arm 120, in one embodiment, the first arm 121 and the second arm 122 may be further arranged at an angle, and a connection portion 125 is formed at the intersection of the first arm 121 and the second arm 122, such that the hinge arm 120 is generally arranged in a curved shape, which can better adapt to the installation environment of the above-mentioned corner, and achieve better force transmission.
The first arm 121 may be fixedly connected to the door body 300. The connection mode of the two is not limited, and may be one or more of screw fixing, snap fixing, adhesive fixing and adsorption fixing. In some embodiments, as shown in FIG. 10, threaded holes are provided at the corresponding positions of the first arm 121 and the door body 300, the first arm 121 and the threaded hole on the door body 300 are sequentially connected by a screw member, to realize the connection and fixation between the first arm 121 and the door body 300.
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 by elastic structures such as a pull cord and/or a tension spring. Based on this, the second arm 122 may be provided with a hook portion, the second arm 122 is detachably connected to the elastic structure such as the pull cord and/or the tension spring through the hook portion, which is more convenient for disassembly and fixation.
The connection portion 125 is provided with a shaft hole, the shaft hole may be provided with a notch on one side, and the rotating shaft 110 is rotatably matched with the shaft hole. The connection portion 125 may further be provided with a reinforcing rib protruding from the periphery of the shaft hole, and the reinforcing rib can increase the connection and matching strength of the shaft hole.
In addition, the drive arm 130 is rotatably connected to the hinge arm 120. In some embodiments, as shown in FIG. 3 to FIG. 4 and FIG. 11, the drive arm 130 has a first drive end 131, a second drive end 132 and a middle 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 to each other, or may be arranged at intervals of any angle. The first drive end 131 is closer to the main body 200, and the first guide mechanism 150 is disposed between the first drive end 131 and the mounting member 140. The second drive end 132 is closer to the door body 300, the second guide mechanism 170 is disposed between the second drive 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 drive end 131 is restricted by the first guide mechanism 150. It can be understood that, since the panel 400 has a movable stroke relative to the door body 300, when the door body 300 rotates, the movement of the hinge arm 120 causes the force of the drive arm 130 to change the position. The first guide mechanism 150 constrains the drive arm 130, so that the rotation trajectory and the rotation stroke amount of the drive arm 130 can be defined. 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 preset stroke, which drives the second drive end 132 to change its position. The position change of the second drive end 132 may be a linear trajectory or an arc-shaped trajectory. The setting of the second guide mechanism 170 is to restrict the linear translation of the moving member 160 along the first direction, to achieve the purpose of linking the panel 400 to translate along the first direction through the opening and closing movement of the door body 300.
In this embodiment, during the rotation stroke of the door body 300, the drive arm 130 rotates along with the rotation of the hinge arm 120. That is, the hinge arm 120 is rotationally connected to the drive arm 130, and through the rotational connection between the two, the purpose of linking the drive arm 130 to rotate with the hinge arm 120 is achieved.
In some embodiments, the drive 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 rotating shaft 110, which is equivalent to making the drive arm 130 rotate around the rotating shaft 110 along with the rotation of the hinge arm 120.
In some embodiments, the rotational connection of the drive arm 130 is spaced from the rotating shaft 110, so that when the door body 300 rotates, the drive arm 130 revolves around the rotating shaft 110 along with the rotation of the hinge arm 120. In this way, the drive arm 130 can follow the hinge arm 120 to move toward the door body 300, the drive arm 130 is approached in the first direction as a whole, which is more helpful for driving the moving member 160 to translate in the first direction.
In an embodiment, when the door body 300 is rotated to open the main body 200, at least the second drive end 132 of the drive arm 130 approaches the door body 300. Since the second drive end 132 is connected to the moving member 160 and the second guide mechanism 170 is connected therebetween, when it is ensured that at least the second drive end 132 on the drive arm 130 is close to the door body 300, that is, the second drive end 132 can realize the movement of the moving member 160 in the first direction through the second guide 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, which can be a sliding pin and a sliding groove that cooperate with each other, as long as the constraint on the drive arm 130 can be realized and the drive arm 130 can be driven to move. When the door body 300 is opened, 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 body 300. When the hinge arm 120 is rotated and opened, the drive arm 130 can drive the second drive end 132 to drive the panel 400 to move relative to the door body 300 along the first direction and away from the installation end. On the contrary, when the door body 300 is closed, the moving end rotates close to the main body 200. Through the setting of the first guide mechanism 150 and the second guide mechanism 170, during the process of rotating and closing the hinge arm 120, the drive arm 130 can drive the second drive end 132 to drive the panel 400 to move relative to the door body 300 along the first direction and the direction close to the installation end, the movement trajectory of the first drive end 131 gradually moves away from the direction of the door body 300.
It can be understood that the first guide mechanism 150 may be provided between the drive arm 130 and the main body 200, for example, the sliding pin or sliding groove is directly formed on the main body 200, and the sliding groove or sliding pin is correspondingly provided on the drive arm 130. With this arrangement, the hinge 100 has fewer components and occupies a smaller space, which is beneficial to maximizing the size of the electrical device.
The first guide mechanism 150 is provided with a sliding pin or a sliding groove 123 through a mounting member 140 provided separately from the main body 200. The mounting member 140 may be connected to the main body 200 by means of bolts, welding or the like. Compared with the technical solution of directly processing on the main body 200, in this embodiment, the mounting member 140 provided separately is used to cooperate with the drive arm 130, the first guide mechanism 150 is provided between the mounting member 140 and the drive arm 130, so that the hinge 100 is easier to manufacture and has a lower production cost. In addition, the structure of the existing electrical device can be used, and there is no need to re-open the mold, which reduces the cost of research and development, and is also beneficial to the application of different materials for the hinge 100 and the main body 200.
As shown in FIG. 1 and FIG. 3 to FIG. 5, in some embodiments, the mounting member 140 may be fixedly connected to the main body 200 through structural connections such as bolts. The first guide mechanism 150 includes a first guide pin 151 and a first guide groove 152 respectively disposed on the drive arm 130 and the mounting member 140. In some embodiments, the first guide pin 151 may be provided on the first drive end 131 of the drive arm 130, the first guide groove 152 may be provided on the mounting member 140. In some embodiments, the first guide pin 151 may be provided on the mounting member 140, and the first guide groove 152 may be provided 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 member 140 can be realized. The first guide pin 151 matches with the first guide groove 152 (inserted into each other), such that when the door body 300 is opened, the movement trajectory of the second drive end 132 gradually approaches the direction of the door body 300. On the contrary, during the closing stroke of the door body 300, the movement trajectory of the second drive end 132 gradually moves away from the door body 300.
Through the above structural arrangement, during the opening stroke of the door body 300, when the first drive end 131 of the drive arm 130 is pulled to move in a direction close to the door body 300, the rotation is also restricted by the cooperation of the first guide pin 151 and the first guide groove 152. Thus, the second drive end 132 of the drive arm 130 is driven to drive the moving member 160 to move in the direction of the moving end of the door body 300. On the contrary, during the closing stroke of the door body 300, when the first drive end 131 of the drive arm 130 is moved in a direction close to the main body 200, the rotation is also restricted by the cooperation of the first guide pin 151 and the first guide groove 152, therefore, the second drive end 132 of the drive arm 130 is driven to drive the moving member 160 to move in the direction of the door body 300 toward the installation end. In this embodiment, the linkage between the opening or closing of the door body 300 and the movement of the panel 400 along the door body 300 can be realized through the arrangement of the first guide pins 151 and the first guide grooves 152. The structure is simple and reliable. Compared with complex transmission structures such as multi-stage gears, it is not easy to be stuck, easy to manufacture, and low in production cost.
In this embodiment, as shown in FIG. 1 to FIG. 6, the first guide pin 151 is disposed on the first drive end 131, the first guide groove 152 is disposed on the mounting member 140, and the first guide groove 152 is bent from the main body 200 toward the door body 300. The specific shape of the first guide groove 152 can be various, for example, it can be a straight line or an arc shape, or a combination of a straight line and an arc shape, as long as the drive arm 130 can be restricted. During the process of opening or closing the hinge arm 120, the second drive end 132 of the drive arm 130 may drive the moving member 160 to move along the door body 300 toward the installation end or the moving end.
As described above, the first guide groove 152 may be linear (the whole is linear without obvious bending). When the first guide groove 152 is linear, the first guide groove 152 may extend laterally or be inclined from the main body 200 toward the door body 300. Compared with the linear shape, the curved first guide groove 152 may have lower resistance to a certain extent, and according to the design, the movement of the panel 400 may be non-uniform. 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 avoid the occurrence of j amming.
Besides, it is possible to simply adapt the shape of the first guide groove 152 to meet the design requirements of the movement stroke of the panel 400 relative to the door body 300, such as adapting to the installation environment of different electrical equipment and the way of opening the door, the first guide groove 152 is divided into different groove segments, and the shapes and extending directions of at least part of the groove segments can be set differently, not only can a variety of stroke designs be realized, but also easy to realize, with low R&D cost and high reliability.
Similarly, as shown in FIG. 1 to FIG. 6, the second guide mechanism 170 includes a second guide pin 171 and a second guide groove 172, and the second guide pin 171 is inserted into the second guide groove 172. In this embodiment, the second guide groove 172 may be provided on the moving member 160, and the second guide pin 171 may be provided on the second drive end 132 of the drive arm 130 or near the second drive end 132. In other embodiments, the second guide groove 172 may also be provided on the drive arm 130, and the second guide pin 171 may be provided on the moving member 160. In this embodiment, the second guide groove 172 is matched (inserted) with the second guide pin 171.
Further, the second guide groove 172 extends along the stacking direction between the panel 400 and the door body 300. That is, the second guide groove 172 extends along the thickness direction of the panel 400 and the door body 300. It can be understood that when the second drive end 132 of the drive arm 130 moves toward the door body 300 following the movement of the middle section 133, can be decomposed to have components along the first direction and along the above-mentioned stacking direction. When the second guide grooves 172 extend along the stacking direction, equivalent to decomposing the component of the second drive end 132 along the first direction and the component along the stacking direction, the component along the stacking direction is 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 along the first direction as a whole, and then pushes the panel 400 to move relative to the door body 300 along the first direction.
The moving member 160 can be directly slidably connected to the door body 300, that is, an elongated slot may be provided on the door body 300 or at the connection between the door body 300 and the panel 400, and the moving member 160 slides along the elongated slot. In this embodiment, as shown in FIG. 2, FIG. 4 and FIG. 6, the moving member 160 is slidably connected to the hinge arm 120 to realize the movement of the panel 400 relative to the door body 300. It can be understood that the first arm 121 of the hinge arm 120 can be fixed relative to the door body 300. 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 body 300, the panel 400 connected to the moving member 160 can also translate relative to the door body 300. The moving member 160 is slidingly connected to the hinge arm 120, such that at least the moving member 160 and the hinge arm 120 in the hinge 100 can be pre-installed to form a whole, which is beneficial to the compact structure of the hinge 100, at the same time, compared with the solution that needs to install the first arm 121 and the moving member 160 to the door body 300 one by one, it is helpful to simplify the installation operation.
