DETAILED DESCRIPTION

[0029] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0030] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The descriptions of "first", "second", etc. in the embodiments of the present application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically limited.

[0031] When the embedded device is installed in the cabinet, the gap at the bottom tends to decrease gradually, which also shows that the embedded device is developing towards a more integrated, easier to install and more beautiful direction. In the related art, the embedded device such as the oven is installed in a cabinet of custom size. The gap between the left and right sides of the embedded device and the cabinet is 2.5mm, the upper gap is 6mm, and the bottom gap is 15.5mm. This is because the door body of the embedded device in the prior art is rotatably connected to the box body by a hinge. The hinge includes a fixed seat, a rotating shaft and a hinge shell. The fixed seat 1 is fixed on the box body, the hinge shell is fixed on the door body, and the rotating shaft is passed through the fixed seat and the hinge shell. That is to say, when the door body rotates, the rotating shaft is used as a fixed rotating shaft, and the bottom part of the door body will also rotate with the rotating shaft as a fixed rotating shaft. Since its rotation radius is fixed, in order to avoid interference between the door body and the cabinet, the bottom of the cabinet will be sunk by 10mm, which will cause the gap between the embedded device and the cabinet to become larger, easy to accumulate dust and difficult to clean.

[0032] In order to better understand the hinge of the embedded device provided in the present application, the embedded device is first described.

[0033] On one hand, an embodiment of the present application provides an embedded device, and the embedded device includes a hinge 100 .

[0034] Exemplarily, the embedded device includes a box body and a door body, the box body is formed with a receiving cavity and a take-in and put-out opening communicating with the receiving cavity, and the hinge 100 is connected between the door body and the box body to open or close the take-in and put-out opening.

[0035] Another aspect of the present application embodiment provides a hinge 100 for an embedded device. Figures 1 to 7 The hinge 100 includes a fixing seat 1, a mounting shell 2 and a connecting rod 3. The fixing seat 1 is arranged on the box body. The mounting shell 2 is arranged on the door body. The connecting rod 3 is hinged to the fixing seat 1 and the mounting shell 2 at both ends along its length direction, and the door body can move upward in the process of rotating the door body to open the access opening.

[0036] Exemplarily, the fixing seat 1 may be disposed at the front end of the bottom of the box body, and the mounting shell 2 may be disposed at the bottom of the door body.

[0037] The hinge 100 of the embedded device provided in the present application has a fixed seat 1 set on the box body, a mounting shell 2 set on the door body, and a connecting rod 3 is hinged to the fixed seat 1 and the mounting shell 2 at both ends along its length direction, that is, the connecting rod 3 and the mounting shell 2 can rotate around the fixed seat 1, and the mounting shell 2 and the connecting rod 3 can also rotate relative to each other. In this way, when the door body is rotated, the mounting shell 2 connected to the door body can rotate around one end of the connecting rod 3 along its length direction, so that the door body can be rotated away from the box body to open the access port or the door body can be rotated towards the box body to close the access port; the other end of the connecting rod 3 along its length direction is hinged to the fixed seat 1 and the mounting shell 2 is hinged to the door body. The seat 1 is hinged, and the mounting shell 2 can rotate around the fixed seat 1 with the connecting rod 3 as the radius, thereby driving the door body to rotate upward or downward. In this way, the bottom of the door body can move upward in the process of pulling down and rotating the door body to open the access port. In this way, on the one hand, the probability of interference between the door body and the cabinet can be reduced to increase the service life of the embedded device and the cabinet, as well as the smoothness of opening and closing the door; on the other hand, when the access port is opened, the door body can move upward, so that the cabinet does not need to be designed to sink, and the gap between the bottom of the embedded device and the cabinet can be reduced. The appearance is beautiful, and it is not easy to accumulate dust and is easy to clean.

[0038] After the embedded device provided in the embodiment of the present application is installed in the cabinet, the interference between the door body and the cabinet can be reduced during the process of opening and closing the access opening of the door body, and there is no need to sink the bottom design of the cabinet to reduce the gap between the embedded device and the cabinet. The appearance is beautiful, dust is not easy to accumulate, and it is easy to clean.

[0039] It should be noted that top refers to the direction towards the ceiling, down is opposite to up, front is the side towards the user, and back is opposite to front. The top and bottom directions, front and back directions, and left and right directions are perpendicular to each other and together constitute a three-dimensional vertical coordinate system.

[0040] It should be noted that Figure 1 R1 can be the top-bottom direction, R2 can be the front-back direction, and R3 can be the left-right direction.

[0041] Exemplarily, in one embodiment, the door body is formed with a handle, and the handle and the mounting shell 2 are respectively arranged on both sides of the door body along the top and bottom directions, so that the user can pull the handle downward to drive the door body to rotate downward to open the access opening or pull the handle upward to drive the door body to rotate upward to close the access opening.

[0042] Exemplarily, in one embodiment, the embedded device may be an embedded oven, an embedded dishwasher, or an embedded microwave oven, etc.

[0043] Exemplarily, in one embodiment, the fixing base 1 can be fixed to the box body by fasteners such as screws or bolts, and the mounting shell 2 can be fixed to the door body by fasteners such as screws or bolts.

[0044] For example, in one embodiment, please refer to Figure 1 The two ends of the connecting rod 3 along its length direction are respectively a first hinged end 3a and a second hinged end 3b. The first hinged end 3a is hinged to the mounting shell 2, and the second hinged end 3b is hinged to the fixing seat 1.

[0045] Exemplarily, in one embodiment, the shape of the fixing seat 1 is not limited. For example, the fixing seat 1 may be a rectangular box with an opening on the front side, and the second hinged end 3 b of the connecting rod 3 passes through the opening and is hinged to the inner wall of the fixing seat 1 .

[0046] Exemplarily, in one embodiment, the shape of the mounting shell 2 is not limited. For example, the mounting shell 2 can be a rectangular shell with an escape opening on the rear side, and the first hinged end 3a of the connecting rod 3 passes through the escape opening and is hinged to the inner wall of the mounting shell 2.

[0047] Exemplarily, in one embodiment, the shape of the connecting rod 3 is not limited, for example, the shape of the connecting rod 3 can be flat.

[0048] In one embodiment, please refer to Figures 1 to 7 The connecting rod 3 is respectively formed with a first rotating hole 3c and a second rotating hole 3d on both sides along its length direction, the mounting shell 2 is formed with a third rotating hole 2a, the fixing seat 1 is formed with a fourth rotating hole 1a, the hinge 100 includes a first rotating shaft pin 4 and a second rotating shaft pin 5, the first rotating shaft pin 4 is penetrated through the first rotating hole 3c and the third rotating hole 2a, and the first rotating shaft pin 4 is penetrated through the second rotating hole 3d and the fourth rotating hole 1a.

[0049] Exemplarily, the first hinge end 3a is formed with a first rotating hole 3c, the second hinge end 3b is formed with a second rotating hole 3d, the mounting shell 2 is formed with a third rotating hole 2a, the fixing seat 1 is formed with a fourth rotating hole 1a, the first rotating shaft pin 4 is inserted in the first rotating hole 3c and the third rotating hole 2a, and the second rotating shaft pin 5 is inserted in the second rotating hole 3d and the fourth rotating hole 1a. In this way, the connecting rod 3 can rotate with the second rotating shaft pin 5 as the rotating axis, and then drive the mounting shell 2 and the door body to rotate upward or downward. In this way, when the access port is opened, the door body can rotate upward to make the door body away from the bottom of the cabinet to avoid interference. When the access port is closed, the door body can rotate downward so that the door body can cover the gap between the bottom of the embedded device and the cabinet, and the appearance is beautiful.

[0050] In one embodiment, please refer to Figures 1 to 7 The number of connecting rods 3, first rotating shaft pins 4, second rotating shaft pins 5, third rotating holes 2a and fourth rotating holes 1a are all two, and the two connecting rods 3 are distributed along the top and bottom directions. Each first rotating shaft pin 4 is passed through the corresponding first rotating hole 3c and the corresponding third rotating hole 2a, and each second rotating shaft pin 5 is passed through the corresponding second rotating hole 3d and the corresponding fourth rotating hole 1a.

[0051] In this way, each connecting rod 3 can not only participate in supporting the door body, but also improve the connection strength between the mounting shell 2 and the fixing seat 1, so that the door body has good stability when opening and closing.

[0052] In one embodiment, please refer to Figures 1 to 7 The two connecting rods 3 are respectively a main connecting rod 3e and a sub-connecting rod 3f, the sub-connecting rod 3f is higher than the main connecting rod 3e along the top-bottom direction, the fourth rotating hole 1a corresponding to the main connecting rod 3e is the main fourth rotating hole 1a1, the fourth rotating hole 1a corresponding to the sub-connecting rod 3f is the sub-fourth rotating hole 1a2, the third rotating hole 2a corresponding to the main connecting rod 3e is the main third rotating hole 2a1, the third rotating hole 2a corresponding to the sub-connecting rod 3f is the sub-third rotating hole 2a2, the hole distance between the sub-fourth rotating hole 1a2 and the sub-third rotating hole 2a2 is the first hole distance, the hole distance between the sub-third rotating hole 2a2 and the main third rotating hole 2a1 is the second hole distance, the hole distance between the main third rotating hole 2a1 and the main fourth rotating hole 1a1 is the third hole distance, the hole distance between the main fourth rotating hole 1a1 and the sub-fourth rotating hole 1a2 is the fourth hole distance, the sum of the first hole distance and the second hole distance is less than the sum of the third hole distance and the fourth hole distance, and the first hole distance is greater than the third hole distance.

[0053] In this way, the main connecting rod 3e, the secondary connecting rod 3f, the mounting shell 2 and the fixed seat 1 can constitute a four-link 3 structure. Because the fixed seat 1 is arranged on the box body, which is equivalent to a "frame", the sum of the first hole distance and the second hole distance is less than the sum of the third hole distance and the fourth hole distance, which meets the rod length condition. Therefore, the four-link 3 structure is a double rocker structure with a dead point. When the door body rotates to make the pressure angle reach 90°, the connecting rod 3 can support and limit the door body from continuing to rotate so that it can hover at a suitable angle, thereby improving the convenience of use. When the door body is rotated downward to open the access opening, since the first hole spacing is larger than the third hole spacing, that is, the rotation radius of the main connecting rod 3e is smaller than the rotation radius of the secondary connecting rod 3f, during rotation, the main third rotating hole 2a1 can rotate relative to the secondary third rotating hole 2a2, so that in the process of opening the access opening, the angle between the first hole spacing and the second hole spacing is reduced, and the angle between the second hole spacing and the third hole spacing is increased. In this way, the entire mounting shell 2 can be made to change track upward and backward to reduce the interference between the door body and the bottom of the cabinet, improve the service life of the embedded device and the cabinet, and the bottom of the cabinet does not need to be designed to sink. In this way, the gap between the bottom of the cabinet and the embedded device can be reduced, the appearance is beautiful, and it is not easy to accumulate dust and is easy to clean.

[0054] In one embodiment, please refer to Figures 1 to 7The main fourth rotating hole 1a1 and the auxiliary fourth rotating hole 1a2 are arranged at intervals on both sides of the fixing base 1 along the top-bottom direction, and the auxiliary third rotating hole 2a2 is located on the side of the main third rotating hole 2a1 away from the fixing base 1. When the access port is closed, the height of the auxiliary third rotating hole 2a2 from the ground is higher than the height of the main third rotating hole 2a1 from the ground. When the access port is opened, the height of the auxiliary third rotating hole 2a2 from the ground is lower than the height of the main third rotating hole 2a1 from the ground.

[0055] Exemplarily, the main fourth rotating hole 1a1 is located at the bottom side of the fixing seat 1 along the top-to-bottom direction, the secondary fourth rotating hole 1a2 is located at the top side of the fixing seat 1 along the top-to-bottom direction, and the secondary third rotating hole 2a2 is located at the side of the main third rotating hole 2a1 away from the fixing seat 1 along the left-right direction. When the access port is closed, the secondary third rotating hole 2a2 is higher than the main third rotating hole 2a1 in height above the ground. When the access port is opened, the secondary third rotating hole 2a2 is lower than the main third rotating hole 2a1 in height above the ground. The secondary third rotating hole 2a2 is diagonally arranged with the main third rotating hole 2a1. That is to say, when the access port is closed, the secondary third rotating hole 2a2 is located above the front side of the main third rotating hole 2a1. When the access port is opened, the secondary third rotating hole 2a2 is located below the front side of the main third rotating hole 2a1. The secondary third rotating hole 2a2 is diagonally arranged with the main third rotating hole 2a1.

[0056] In this way, when it is necessary to rotate the door body downward to open the access opening, the secondary third rotating hole 2a2 begins to rotate with the secondary connecting rod 3f as the radius and the secondary fourth rotating hole 1a2 as the center, and the main third rotating hole 2a1 begins to rotate with the main connecting rod 3e as the radius and the main fourth rotating hole 1a1 as the circle. Since the first hole spacing is greater than the third hole spacing, the main third rotating hole 2a1 can rotate upward relative to the secondary third rotating hole 2a2, so that the main third rotating hole 2a1 rotates from the lower rear side of the secondary third rotating hole 2a2 to the upper rear side. In this way, the mounting shell 2 can change track upward and backward. When the door body rotates to the point where the line connecting the first hole spacing coincides with the line connecting the second hole spacing, that is, the four-link 3 structure reaches the dead point, the secondary connecting rod 3f and the main connecting rod 3e can support and limit the door body from continuing to rotate. At this time, the access opening is in an open state.

[0057] In one embodiment, please refer to Figures 1 to 7 The connecting rod 3 includes a connecting portion 31 and a bending portion 32 . The connecting portion 31 is hinged to the fixing seat 1 . One end of the bending portion 32 is connected to the connecting portion 31 . The other end of the bending portion 32 is bent downward and hinged to the mounting shell 2 .

[0058] For example, the main connecting rod 3e may include a main connecting portion 31 and a main bending portion 32, the main connecting portion 31 is formed with a main fourth rotating hole 1a1, the main bending portion 32 is formed with a main third rotating hole 2a1, the secondary connecting rod 3f may include a secondary connecting portion 31 and a secondary bending portion 32, the secondary connecting portion 31 is formed with a secondary fourth rotating hole 1a2, the secondary bending portion 32 is formed with a secondary third rotating hole 2a2, the second rotating shaft pin 5 is divided into a main second rotating shaft pin 5a and a secondary second rotating shaft pin 5b, and the first rotating shaft pin 4 is divided into a main first rotating shaft pin 4a and a secondary first rotating shaft pin The rotating shaft pin 4b, the first rotating hole 3c is divided into the main first rotating hole 3c1 and the secondary first rotating hole 3c2, the second rotating hole 3d is divided into the main second rotating hole 3d1 and the secondary second rotating hole 3d2, the main first rotating shaft pin 4a is penetrated in the main first rotating hole 3c1 and the main third rotating hole 2a1, the secondary first rotating shaft pin 4b is penetrated in the secondary first rotating hole 3c2 and the secondary third rotating hole 2a2, the main second rotating shaft pin 5a is penetrated in the main second rotating hole 3d1 and the main fourth rotating hole 1a1, and the secondary second rotating shaft pin 5b is penetrated in the secondary second rotating hole 3d2 and the secondary fourth rotating hole 1a2. The bending portion 32 is bent downward. On the one hand, the secondary connecting rod 3f and the main connecting rod 3e can avoid each other, thereby improving the stability of the door body when rotating. On the other hand, when the line connecting the first hole distance coincides with the line connecting the second hole distance so that the hinge 100 is at a "dead point", the bent bending portion 32 can better support and limit the door body, thereby improving the working stability of the hinge 100. In the process of turning the door body downward to open the access opening, the door body can achieve upward movement and backward track change movement. For example, it can achieve a track change movement of 8.98mm upward movement and 21.81mm backward movement. In this way, it can not only meet the requirements of not interfering with the cabinet during the process of opening and closing the door, but also do not need to sink the cabinet design, and the appearance is beautiful, and at the same time, it can also meet the requirements of smooth movement of the door body during the process of opening and closing the door.

[0059] In one embodiment, please refer to Figure 1 The hinge 100 includes an elastic component 6 , one end of the elastic component 6 is connected to an end of the mounting shell 2 away from the hinge 100 , and the other end of the elastic component 6 is connected to the connecting rod 3 .

[0060] Exemplarily, the elastic component 6 can be arranged in the mounting shell 2, and the mounting shell 2 is formed with a through hole 2b extending in the left and right directions on one side away from the hinge 100 along its length direction. The hinge 100 includes a hanging shaft 7, and the hanging shaft 7 is passed through the through hole 2b. The elastic component 6 has a hook, which can be hung on the hanging shaft 7. The other end of the elastic component 6 is connected to the connecting rod 3. In the process of rotating the door body downward to open the access port, the distance between the hook shaft A and the connecting rod 3 will increase, so that the elastic component 6 undergoes elastic deformation, and the elastic force generated by it can act on the connecting rod 3. , and then it can act on the door body to balance the torque generated by the weight of the door body and realize the hovering of the door body at any angle. Compared with the two-stage door body in the opening process in the prior art, the present application provides an embedded device, which can reduce the sense of frustration and has good smoothness in the process of opening and closing the access port of the door body; when the door body is rotated upward to close the access port, the distance between the hook axis A and the connecting rod 3 becomes smaller, and the elastic component 6 restores the deformation, which can provide a closing force for the closing of the door body. The closing force is greater than the torque generated by the weight of the door body, and the door body can be automatically closed.

[0061] In one embodiment, please refer to Figures 1 to 7 There are two connecting rods 3, the two connecting rods 3 are respectively a main connecting rod 3e and a secondary connecting rod 3f, the secondary connecting rod 3f is higher than the main connecting rod 3e along the top-to-bottom direction, the elastic component 6 includes a first elastic member 61, a second elastic member 62, a first transmission rod 63 and a second transmission rod 64, one end of the first elastic member 61 is connected to the mounting shell 2, the other end of the first elastic member 61 is hinged to one end of the first transmission rod 63 along its length direction, the other end of the first transmission rod 63 along its length direction is hinged to the main connecting rod 3e, one end of the second elastic member 62 is connected to the hinge point between the first elastic member 61 and the first transmission rod 63, the other end of the second elastic member 62 is hinged to one end of the second transmission rod 64 along its length direction, and the other end of the second transmission rod 64 is slidably connected to the secondary connecting rod 3f.

[0062] Exemplarily, the first elastic member 61 forms a hook, which can be hung on the hanging shaft 7, the other end of the first elastic member 61 is hinged to one end of the first transmission rod 63 along its length direction, the other end of the first transmission rod 63 along its length direction is formed with a main fifth rotation hole 63a, the main connecting rod 3e is formed with a sixth rotation hole 3e1, the sixth rotation hole 3e1 is located between the main first rotation hole 3c1 and the main second rotation hole 3d1, the hinge 100 includes a main connecting pin 8 and a secondary connecting pin 9, the main connecting pin The nail 8 is passed through the main fifth rotating hole 63a and the sixth rotating hole 3e1, one end of the second elastic member 62 is connected to the hinge point of the first elastic member 61 and the first transmission rod 63, and the second transmission rod 64 is formed with a transfer hole 64b running through the left and right directions at one end along its length direction, and the secondary connecting pin 9 is passed through the transfer hole 64b, and the second elastic member 62 is formed with a hook, which can be hung on the secondary connecting pin 9, and the other end of the second transmission rod 64 along its length direction is slidably connected to the secondary connecting rod 3f.

[0063] In this way, in the process of rotating the door body downward to open the access port, the main connecting rod 3e is connected to the first elastic member 61 through the first transmission member, and the secondary connecting rod 3f is connected to the first elastic member 61 through the second transmission member and the second elastic member 62. In the process of rotating the door body, the main connecting rod 3e can cause the first elastic member 61 to undergo elastic deformation, and the secondary connecting rod 3f can cause both the first elastic member 61 and the second elastic member 62 to undergo elastic deformation. In this way, the door body can be automatically closed at any angle during the process of opening the access port and closing the access port, and the stability of the door body opening and closing is better.

[0064] It should be noted that the hovering at any angle here means that the door body can hover at an angle with the box body when the access opening is closed or opened. For example, Figure 4 and Figure 5 The door body can be hovered at any angle from 0° to 90°.

[0065] In one embodiment, please refer to Figure 1 , Figures 4 to 7 The secondary connecting rod 3f is formed with a downwardly bent guide groove 3f1, and the hinge 100 includes a directional pin 10 connected to the second transmission rod 64. The directional pin 10 is slidably set in the guide groove 3f1. In the process of closing the access port, the directional pin 10 slides downward from the top end of the guide groove 3f1 to the bottom end of the guide groove 3f1.

[0066] Exemplarily, the guide groove 3f1 can be formed in the portion between the secondary first rotating hole 3c2 and the secondary second rotating hole 3d2 of the secondary connecting rod 3f, and the guide groove 3f1 runs through both sides of the secondary connecting rod 3f along the left-right direction. A secondary fifth rotating hole 64a is formed at one end of the second transmission rod 64 away from the second elastic member 62 along the length direction, and a part of the directional pin shaft 10 is inserted into the secondary fifth rotating hole 64a, and the other part of the directional pin shaft 10 can be slidably inserted into the guide groove 3f1.

[0067] Here, when the door body is rotated, the auxiliary connecting rod 3f will rotate around the fixed seat 1. By setting the guide groove 3f1, the second transmission rod 64 can perform curved motion in the guide groove 3f1 to make it roughly consistent with the rotation direction of the auxiliary connecting rod 3f. In this way, the telescopic direction of the second elastic member 62 can be roughly the same as the length direction of the second transmission rod 64, so as to provide a stable elastic force and improve the smoothness of opening and closing the door body and the access port.

[0068] In one embodiment, please refer to Figures 1 to 7 The hinge 100 includes a hook shaft A, a first transmission rod 63 is formed with a hook hole 63b, the hook shaft A is passed through the hook hole 63b, the first elastic member 61 and the second elastic member 62 are both connected to the hook shaft A, and the mounting shell 2 is formed with a limiting groove 2c extending along the telescopic direction of the first elastic member 61, and the hook shaft A can be slidably set in the limiting groove 2c.

[0069] Exemplarily, the first transmission rod 63 includes a first rod portion 631 and a second rod portion 632, and the first rod portion 631 and the second rod portion 632 are spaced apart in the left-right direction to form an avoidance space 63c. The first rod portion 631 and the second rod portion 632 are both formed with a hook hole 63b at one end close to the first elastic member 61 along their length direction, and the first rod portion 631 and the second rod portion 632 are both formed with a main fifth rotation hole 63a at one end away from the first elastic member 61 along their length direction. The connecting pin is penetrated through the sixth rotation hole 3e1 and the two main fifth rotation holes 63a, and the hook axis A is penetrated through the two hook holes 63b. The hook of the first elastic member 61 is hooked on the part of the hook axis A located in the avoidance space 63c. The second elastic member 62 and the second transmission rod 64 are both located in the avoidance space 63c, and the hook of the second elastic member 62 is hooked on the hook axis A. The mounting shell 2 is formed with a limiting groove 2c extending along the telescopic direction of the first elastic member 61. The limiting groove 2c passes through both sides of the mounting shell 2 along the left and right directions. The hook shaft A passes through the hook hole 63b and partially slides in the avoidance space 63c and is set in the limiting groove 2c. When the door body rotates to pull the first elastic member 61, the telescopic direction of the first elastic member 61 can be limited by sliding the hook shaft A in the limiting groove 2c, so that the telescopic direction of the first elastic member 61 is roughly consistent with the length direction of the first transmission rod 63, so as to provide a stable elastic force, improve the smoothness of opening and closing the door body and the access port, and have a compact structure and high space utilization.

[0070] Exemplarily, in one embodiment, the first elastic member 61 and the second elastic member 62 may both be springs.
