The door opening and closing device 11 provided by the embodiment of the application is mainly applied to the electrical equipment 10 and used for automatically opening or closing the door body 13, and the door opening and closing device 11 can automatically open the door body 13 after receiving a door opening signal. The door opening signal may be triggered by the user or triggered by the electrical apparatus 10 itself. Similarly, the door opening and closing device may automatically close the door 13 after receiving a door closing signal, where the door closing signal may be triggered by a user or triggered by the electrical apparatus 10 itself.
In the embodiment of the present application, the door opening and closing device 11 includes:
a drive mechanism 100;
a linkage gear 300, the linkage gear 300 is rotatably installed on the main body 12 and is in transmission connection with the driving mechanism 100, the linkage gear 300 is provided with a top door part 320;
one end of the revolving door mechanism 400 is connected with the linkage gear 300, and the other end of the revolving door mechanism 400 is used for being connected with the door body 13;
under the condition that the driving mechanism 100 drives the linkage gear 300 to rotate, the top door portion 320 jacks the door body 13, and the rotating door mechanism 400 drives the door body 13 to rotate.
In this embodiment, the top door 320 is disposed on the linkage gear 300, the revolving door mechanism 400 is connected to the linkage gear 300 and the door 13, and under the condition that the driving mechanism 100 drives the linkage gear 300 to rotate, the linkage gear 300 can simultaneously drive the top door 320 and the revolving door mechanism 400 to move, so that the top door 320 can open the door 13, and the revolving door mechanism 400 drives the door 13 to rotate, thereby opening the door 13.
The top door portion 320 is disposed on the linkage gear 300, and under the condition that the linkage gear 300 rotates, the linkage gear 300 can be regarded as directly pushing against the door 13, so that the top door portion 320 can overcome the adsorption force between the door 13 and the main body 12 with a large acting force to push open the door 13, and then the door rotating mechanism 400 can drive the door 13 to rotate with a relatively small force to open the door 13. The user may place items into the body 12 or remove items from the body 12.
In the embodiment of the present application, in order to improve the sealing effect between the door 13 and the main body 12 when the door 13 is closed on the main body 12, the door 13 is usually pressed on the main body 12 with a relatively large pressure, or the door 13 is adsorbed on the main body 12 through an adsorption structure, so that a relatively large adsorption force exists between the door 13 and the main body 12, and when the door 13 is opened, the door 13 and the main body 12 need to be separated from each other by a relatively large action force. The top door part 320 is arranged on the linkage gear 300, and in the rotation process of the linkage gear 300, the top door part 320 directly acts with the door body 13, so that the arrangement of other parts can be reduced, the number of the parts of the door opening and closing device 11 is reduced, and the integration level is improved.
Meanwhile, two functions of a top door and a revolving door can be realized through the same driving mechanism 100, the number of the driving mechanisms 100 of the whole door opening and closing device 11 can be reduced, the number of parts can also be reduced, the integration level of the whole door opening and closing device 11 is improved, and the matching difficulty is reduced.
The term "the top door portion 320 pushes the door 13 open" as used herein means that the top door portion 320 rotates along with the interlocking gear 300 under the condition that the door 13 closes the main body 12, that is, the door 13 is attracted to the main body 12, and the top door portion 320 gradually acts on the door 13 in the process of rotating the top door portion 320, so that the door 13 and the main body 12 are detached from the attraction, thereby pushing the door 13 open.
The door body 13 is firstly jacked open through the top door part 320 arranged on the linkage gear 300, the revolving door mechanism 400 drives the door body 13 to rotate relative to the main body 12 to open the door, the load of the revolving door mechanism 400 can be reduced relative to the direct door opening through the revolving door mechanism 400, the driving force requirement on the driving mechanism 100 can be reduced, the running reliability of the driving mechanism 100 is improved, and the cost of the whole door opening and closing device 100 is reduced.
In this application embodiment, revolving door mechanism 400 mainly used pushes up a door body 13 at top door portion 320 after, drives a door body 13 and continues to rotate for main part 12, makes main part 12 can open great opening, and convenience of customers places or takes article in to main part 12.
In this application embodiment, revolving door mechanism 400 and overhead door portion 320 all are connected with linkage gear 300, and same linkage gear 300 rotates and can drive overhead door portion 320 and revolving door mechanism 400 motion simultaneously promptly, makes same linkage gear 300 can drive overhead door portion 320 and realize the overhead door, drives a body 13 again through revolving door mechanism 400 and rotates for main part 12 to open a body 13.
Namely, the driving mechanism 100 can drive one linkage gear 300 to rotate, so that the functions of a top door and a revolving door can be realized, and the number of parts of the whole door opening and closing device 11 is reduced, thereby reducing the size of the whole door opening and closing device 11, reducing the installation occupation space of the door opening and closing device 11, miniaturizing the door opening and closing device 11, and improving the integration level of the door opening and closing device 11.
In some embodiments, the top door portion 320 is protruded from the linkage gear 300, and under the condition that the driver drives the linkage gear 300 to rotate through the clutch, the top door portion 320 extends out of the main body 12 to push open the door body 13.
The linkage gear 300 is installed on the main body 12, and in order to improve the aesthetic appearance of the entire electrical apparatus 10, the linkage gear 300 is installed above the main body 12 and is not exposed from the opening of the main body 12, the top door 320 is protruded on the linkage gear 300, and under the condition that the driving mechanism 100 drives the linkage gear 300 to rotate, the top door 320 gradually extends out of the main body 12, so as to jack open the door 13 closed at the opening of the main body 12.
In other words, when the door 13 is closed at the opening of the main body 12, the top door 320 is disposed in the main body 12 and does not extend out from the opening, and after the driving mechanism 100 receives the door opening signal, the driving mechanism 100 drives the linkage gear 300 to rotate, so as to drive the top door 320 to gradually extend out of the main body 12, thereby opening the door 13.
In the present application, the top door 320 is disposed in the main body 12, and means that the projection of the top door 320 on the main body 12 completely overlaps with the main body 12, and the top door 320 extends out of the main body 12, i.e., the projection of the top door 320 on the main body 12 extends out of the main body 12.
Referring to fig. 4, in some embodiments, the top door portion 320 has a top door point 321, and under the condition that the driving mechanism 100 drives the linking gear 300 to rotate, the top door point 321 is abutted against the door body 13 to push open the door body 13.
In the process that the driving mechanism 100 drives the linkage gear 300 to rotate, the top door portion 320 gradually contacts with the door body 13, and under the condition that the driving mechanism 100 continues to drive the linkage gear 300 to rotate, the top door portion 320 extends out of the main body 12, so that the top door point 321 jacks the door body 13.
The top door point 321 is a point on the top door 320 farthest from the rotation center of the linkage gear 300, and in the process that the driving mechanism 100 drives the linkage gear 300 to rotate, the top door 320 rotates along with the linkage gear 300, and the top door point 321 can push the door body 13 to the farthest position where the top door 320 can push the door body 13.
Wherein, the top door part 320 can be entrusted with the door body 13 to be pushed by 3 degrees to 5 degrees. The specific angle is flexibly set by the angle required by breaking the door opening resistance of the door body 13.
In some embodiments, the top door portion 320 has a facing surface 322, and the top door point 321 is disposed at one end of the facing surface 322.
The appearance surface 322 is a plane, the top door point 321 is disposed at one end of the appearance surface 322, and when the driving mechanism 100 drives the linkage gear 300 to rotate, a part of the appearance surface 322 rotates onto the main body 12, another part rotates outside the main body 12, and the part outside the main body 12 gradually abuts against the door 13 until the top door point 321 abuts against the door 13, so as to open the door 13.
It is easy to understand that, in the process that the appearance surface 322 rotates along with the linkage gear 300, the portion of the appearance surface 322 extending out of the main body 12 gradually abuts against the door 13, and in the process of rotation, the extending portion of the appearance surface 322 increases to increase the abutting force against the door 13, so that the door 13 can overcome the adsorption force with the main body 12, and the door 13 is pushed open.
In some embodiments, the external appearance surface 322 further has an avoidance point 323 disposed opposite the top door point 321, and the avoidance point 323 is located at a distance from the center of rotation of the linkage gear 300 that is less than the distance from the top door point 321 to the center of rotation of the linkage gear 300.
The avoidance point 323 and the top door point 321 are respectively arranged at two ends of the appearance surface 322, and in the process that the driving mechanism 100 drives the linkage gear 300 to rotate, the top door portion 320 rotates along with the linkage gear 300, the avoidance point 323 rotates to the main body 12 first, the top door point 321 rotates to the outside of the main body 12 first, and along with the rotation of the linkage gear 300, the part of the appearance surface 322 rotating to the outside of the main body 12 is more and more until the top door point 321 abuts against the door body 13, so that the door body 13 is pushed open.
It is easy to understand that, in the process that the top door part 320 rotates along with the linkage gear 300, the part of the appearance surface 322 that rotates to the outside of the main body 12 gradually contacts with the door body 13, in the process that the top door part 320 rotates, the part of the appearance surface 322 that extends out is more and more, and the door body 13 may already be separated from the main body 12 at a certain position, and when the top door point 321 contacts with the door body 13, the door body 13 can be abutted to the farthest position that the whole top door part 320 can be abutted to. That is, the top door point 321 does not necessarily have to be the first to push the door 13, but the top door point 321 is the farthest position against.
In some embodiments, the top door portion 320 further has a first coupling face 324 and a second coupling face 325, the first coupling face 324 couples the top door point 321 with the linkage gear 300, and the second coupling face 325 couples the escape point 323 with the linkage gear 300.
The first connecting surface 324 and the second connecting surface 325 are respectively arranged at two sides of the appearance surface 322, a top door point 321 is formed at the connecting position of the first connecting surface 324 and the appearance surface 322, and an avoiding point 323 is formed at the connecting position of the second connecting surface 325 and the appearance surface 322, which mainly plays a role of connecting the appearance surface 322 and the linkage gear 300, when the top door part 320 rotates along with the linkage gear 300, the avoiding point 323 rotates inwards to the main body 12, and the top door point 321 rotates outwards to the outside of the main body 12, therefore, the included angle between the first connecting surface 324 and the appearance surface 322 is relatively small, and the included angle between the second connecting surface 325 and the appearance surface 322 is relatively large. That is, the included angle between the first connecting surface 324 and the appearance surface 322 is smaller than the included angle between the second connecting surface 325 and the appearance surface 322.
The included angle between the first connection surface 324 and the appearance surface 322 is relatively small, so that the top door point 321 is relatively sharp compared with the avoidance point 323, when the top door point 321 abuts against the door body 13, a large pressure can be locally applied, and the door body 13 can be quickly jacked open.
In some embodiments, the appearance surface 322 is flush with the opening of the main body 12 under the condition that the door body 13 closes the main body 12.
When the door 13 is closed, the appearance surface 322 is flush with the opening of the main body 12, and can be retracted on the main body 12 when the door 13 is closed, so that the whole top door part 320 does not protrude out of the main body 12, and the appearance of the whole door opening and closing device 10 is improved.
In other words, when the door 13 is closed, the appearance surface 322 is flush with the opening of the main body 12, which ensures the aesthetic appearance of the door opening and closing device 11 when it is not activated.
In some embodiments, top door portion 320 and linkage gear 300 are integrally formed. The two are integrally formed, and it can be considered that the linking gear 300 directly abuts against the door 13, so that the top door 320 can overcome the adsorption force between the door 13 and the main body 12 with a large acting force to open the door 13. Meanwhile, 320 pieces of top door parts are arranged independently, so that parts of the whole machine are reduced, and the size of the whole machine is reduced.
In some embodiments, the linkage gear 300 has a mounting slot 340, and the swing door mechanism 400 is mounted in the mounting slot 340.
The revolving door mechanism 400 is arranged in the mounting groove 340, so that the phenomenon that the revolving door mechanism 400 and the linkage gear 300 fall off is avoided, and the transmission between the linkage gear 300 and the revolving door mechanism 400 cannot be realized.
As for the shape and size of the installation groove 340, it may be set according to the specific function of the door opening and closing device 11. If the rotation of the interlocking gear 300 and the opening of the swing door mechanism 400 are simultaneously operated, the width of the installation groove 340 may be the same as the width of the swing door mechanism 400 disposed in the installation groove 340. If the door-opening speed of the swing door mechanism 400 is slower than that of the link gear 300, the width of the installation groove 340 may be set to be larger than the width of the swing door mechanism 400 located in the installation groove 340, and when the driving mechanism 100 drives the link gear 300 to rotate, the link gear 300 may rotate first, and then the swing door mechanism 400 rotates following the link gear 300.
In some embodiments, the width of the mounting slot 340 is greater than the width of the swing door mechanism 400.
It should be noted that the fact that the width of the installation groove 340 is greater than the width of the swing door mechanism 400 means that the width of the installation groove 340 is greater than the width of the swing door mechanism 400 located in the installation groove 340 of the swing door mechanism 400. In the process of driving the linkage gear 300 to rotate by the driving mechanism 100, because the width of the installation groove 340 is greater than the width of the revolving door mechanism 400 in the installation groove 340, a certain amount of movement is provided in the installation groove 340, after the linkage gear 300 is started, the linkage gear 300 drives the top door part 320 to rotate first, so that the top door part 320 jacks up the door body 13 first, when one of the sides rotating to the installation groove 340 abuts against the revolving door mechanism 400, and the revolving door mechanism 400 is pushed to rotate along with the linkage gear 300 to open the door body 13.
It should be noted that the width is a circle formed by taking the rotation center of the linkage gear 300 as a center of circle and taking any length smaller than the radius of the linkage gear 300 as a radius, and the length of the projection of the swing door mechanism 400 and the mounting groove 340 on the circle is the width referred to in this application. And the length of the mounting groove 340 means the length in the radial direction of the interlocking gear 300.
In some embodiments, the linkage gear 300 has a first abutting surface 342, and under the condition that the driving mechanism 100 drives the linkage gear 300 to rotate, the top door portion 320 abuts against the door body 13, and the first abutting surface 342 abuts against the revolving door mechanism 400, so as to push the revolving door mechanism 400 to rotate, so as to open the door body 13.
Under an initial condition, the swing door mechanism 400 is a certain distance away from the first abutting surface 342, after the driving mechanism 100 receives a door opening signal, the driving mechanism 100 drives the linkage gear 300 to rotate forward, the linkage gear 300 rotates relative to the swing door mechanism 400 to drive the top door portion 320 to rotate, so that the top door portion 320 firstly jacks the door body 13, after the top door portion 320 jacks the door body 13, when the first abutting surface 342 of the linkage gear 300 rotates to abut against the swing door mechanism 400, the linkage gear 300 pushes the swing door mechanism 400 to rotate, and the door body 13 is opened.
That is, the link gear 300 and the swing door mechanism 400 rotate asynchronously. During a period of time when the driving mechanism 100 is just started, the revolving door mechanism 400 does not rotate, when the driving mechanism 100 is just started, the linkage gear 300 first drives the top door portion 320 to move, so that the top door portion 320 first pushes the door body 13, after the top door portion 320 pushes the door body 13, when the first abutting surface 342 of the linkage gear 300 rotates to abut against the revolving door mechanism 400, the linkage gear 300 pushes the revolving door mechanism 400 to rotate, so that the door body 13 is opened. After the driving mechanism 100 is started for a period of time, the revolving door mechanism 400 is driven to rotate, so that the transmission stability of the revolving door mechanism 400 can be improved, and the door opening stability can be improved.
Wherein, the first abutting surface 342 is disposed on one side wall of the mounting groove 340. When the mounting groove 340 is not disposed on the linkage gear 300, the first abutting surface 342 may be disposed on a structure protruding from the linkage gear 300, and may abut against the revolving door mechanism 400, and push the revolving mechanism to rotate along with the linkage gear 300.
In some embodiments, the linkage gear 300 further has a second abutting surface 343 spaced from the first abutting surface 342, the swing door mechanism 400 is disposed between the first abutting surface 342 and the second abutting surface 343, the door opening and closing device 11 further includes a reset member 600, the reset member 600 is respectively connected to the linkage gear 300 and the swing door mechanism 400, and when the linkage gear 300 stops or rotates reversely, the reset member 600 drives the swing door mechanism 400 to move in a direction away from the first abutting surface 342, so that the swing door mechanism 400 resets to the second abutting surface 343.
When the linkage gear 300 pushes the swing door mechanism 400 to rotate under the action of the driving force of the driving mechanism 100, because the swing door mechanism 400 does not move along with the linkage gear 300, the reset member 600 is stretched and stretched to the first abutting surface 342 to abut against the swing door mechanism 400, the swing door mechanism 400 rotates along with the linkage gear 300 to push the door body 13, after the door body 13 is opened, the driving mechanism 100 stops working, the reset member 600 drives the swing door mechanism 400 to move in the direction away from the first abutting surface 342 under the action of self restoring force until the swing door mechanism 400 abuts against the second abutting surface 343, so that the swing door mechanism 400 is reset to the second abutting surface 343, and the next door opening or the door closing in time is facilitated.
In the rotation direction of the linkage gear 300, the second abutting surface 343 is arranged in front of the first abutting surface 342, and in an initial condition, the swing door mechanism 400 is arranged close to the second abutting surface 343, and in the process of driving the linkage gear 300 to rotate by the driving mechanism 100, because the swing door mechanism 400 is arranged close to the second abutting surface 342, the swing door mechanism 400 does not rotate along with the linkage gear 300 at the beginning, and in the process, because the linkage gear 300 rotates, the reset member 600 is stretched. After the reset member 600 is stretched to the extreme, the reset member 600 will pull the swing door mechanism 400 to rotate, so that the swing door mechanism 400 can further open the door body 13. When the reset member 600 pulls the swing door mechanism 400 to rotate, the swing door mechanism 400 moves toward the second abutting surface 343 under the action of the restoring force of the reset member 600, that is, the swing door mechanism 400 always moves toward the second abutting surface 343 when the swing door mechanism 400 opens the door. After the swing door mechanism 400 stops moving, the swing door mechanism 400 is disposed close to the second abutting surface 343.
After the door body 13 is opened, if the driving mechanism 100 receives a door closing signal, the driving mechanism 100 drives the linkage gear 300 to rotate reversely, and the second abutting surface 343 abuts against the door rotating mechanism 400, so as to drive the door rotating mechanism 400 to rotate reversely, so as to close the door body 13.
Besides automatic door closing, the door can be manually closed, when the door is manually closed, the process is opposite to the process, a user pushes the door body, the door body drives the swing door mechanism 400 to rotate, the reset piece 600 can be stretched, after the reset piece 600 is stretched to the utmost, the reset piece 600 can be contracted, the swing door mechanism 400 is enabled to move close to the second abutting surface 343 all the time, and after the door body 13 is closed to the main body 12, the structures of the swing door mechanism 400 and the like can be completely reset.
The second abutting surface 343 is disposed on a sidewall of the mounting groove 340 away from the first abutting surface 342. Similarly, if the mounting groove 340 is not disposed on the linkage gear 300 in other embodiments, the second abutting surface 343 may be disposed on a structure protruding from the linkage gear 300, and the first abutting surface 342 and the second abutting surface 343 may be disposed opposite to each other. And the gap between the first supporting surface 342 and the second supporting surface 343 can also be considered as the mounting groove 340.

In some embodiments, the driving mechanism 100 is activated after receiving the door opening signal, and drives the linkage gear 300 to rotate forward, so as to drive the door 13 to rotate through the rear link 420 and the front link 410, thereby opening the door 13. Conversely, when the driving mechanism 100 receives a door closing signal, the driving mechanism 100 drives the linkage gear 300 to rotate reversely, and also drives the door body 13 to rotate reversely through the rear link 420 and the front link 410, so as to close the door body 13.
The door opening signal may be triggered by the user, or may be triggered by the electrical apparatus 10 itself. Similarly, the door opening and closing device may automatically close the door body 13 after receiving a door closing signal, where the door closing signal may be triggered by a user or triggered by the electrical apparatus 10 itself.
In some embodiments, one of the first connection portion 413 and the second connection portion has a connection groove 414, and the other of the first connection portion 413 and the second connection portion is snapped into the connection groove 414, and the connection groove 414 can have a supporting function, so that the connection groove can be limited from multiple directions, and the risk that the first connection portion 413 and the second connection portion 424 fall off can be reduced, thereby improving the fixing effect of the front link 410 and the rear link 420.
It is easily understood that one of the first connection portion 413 and the second connection portion 424 has the connection groove 414, the first connection portion 413 has the connection groove 414, the second connection portion 424 is snapped into the connection groove 414, and the second connection portion 424 has the connection groove 414, and the first connection portion 413 is snapped into the connection groove 414. In the embodiment of the present application, for convenience of description, the first connection portion 413 having the connection groove 414 and the second connection portion 424 being snapped into the connection groove 414 will be described in detail. This may be so when the second connection has a connection slot 414.

The first and second fixing plates 415 and 416 are spaced apart on the Y-axis, and the connection plate 417 extends along the X-axis. That is, the connecting groove 414 is a through groove in the X-axis direction and has an opening in the Z-axis direction. The rear link 420 is snapped into the coupling groove 414 from an opening opposite the coupling plate 417.
Similarly, since the rear link 420 is also elongated and is provided with a through groove in the X-axis direction, interference between the front link 410 and the rear link 420 when the door opening and closing device 11 drives the door 13 can be reduced, and abnormal noise caused by the interference between the two can be reduced.
The connecting plate 417 is connected to one side of the first fixing plate 415 and one side of the second fixing plate 416, so that the depth of the connecting groove 414 is increased, the second connecting portion 424 of the rear link 420 can be completely clamped into the connecting groove 414 as much as possible, the risk that the second connecting portion 424 is separated from the connecting groove 414 is reduced, and the fixing effect of the first connecting portion 413 and the second connecting portion 424 is improved.
Referring to fig. 7 and 8, it should be noted that the above discloses one connection manner of the front link 410 and the rear link 420, and other connection manners in addition to the above, which are specifically as follows: the swing door mechanism 400 further comprises a connecting assembly 430, the connecting assembly 430 comprises a fixed member 431, a rotating member 432 and a wear-resistant member 433, the wear-resistant member 433 is rotatably connected with the fixed member 431 through the rotating member 432, one of the front connecting rod 410 and the rear connecting rod 420 is fixedly connected with the wear-resistant member 433, and the other one is fixedly connected with the fixed member 431.

That is, the front link 410 and the rear link 420 are both fixedly connected to the connecting assembly 430, and when the front link 410 and the rear link 420 rotate with each other, the front link 410 and the rear link 420 do not rotate, so that the wear of the front link 410 and the rear link 420 is reduced, the service lives of the front link 410 and the rear link 420 are prolonged, and the service life of the whole door opening and closing device 11 is prolonged.

That is, in the embodiment of the present application, although the front link 410 and the rear link and connecting assembly 430 are both fixedly connected, rotation between the front link 410 and the rear link 420 may be achieved by rotation between structures of the connecting assembly 430 itself, due to different connected components. That is, although one of the front link 410 and the rear link 420 is fixedly connected to the wear member 433 and the other is fixedly connected to the fixing member 431, the front link 410 and the rear link 420 can still rotate relative to each other.
