Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a door body assembly and a refrigeration device. Background Art

[0002] With the increasing demand for the integration of household appliances and home furnishings, the embedded design of household appliance products has become a trend. Most refrigerators on the market currently use single-axis or double-axis hinges to achieve the rotational connection between the refrigerator door and the refrigerator body. This design is mainly to meet the embedding requirements of the refrigerator, ensuring that the refrigerator door does not exceed the side of the refrigerator during the process of opening and closing the door, thereby avoiding interference with the side cabinet wood boards.

[0003] However, in order to pursue a better home integration effect, sometimes it is necessary to fixedly connect a door panel to the surface of the box door. Although this design can reduce the integration degree of the appliance and the home, it also increases the thickness of the entire door body assembly. This results in that after the appliance is pushed into the cavity, relying only on the original single-axis or double-axis hinge, the door body assembly with the door panel may interfere with the side of the installation space body during the process of opening and closing the door, thus causing the door body assembly of the appliance to be unable to be opened or closed normally.

[0044] With the increasing demand for the integration of household appliances and home furnishings, the embedded design of household appliances has become a trend. Most refrigerators on the current market use single-axis or double-axis hinges to achieve the rotational connection between the refrigerator door and the refrigerator body. This design is mainly to meet the embedding requirements of the refrigerator, ensuring that the refrigerator door does not exceed the side of the refrigerator during the process of opening and closing the door, thereby avoiding interference with the side cabinet wood boards.

[0045] However, in order to pursue a better home integration effect, sometimes it is necessary to fixedly connect a door panel to the surface of the cabinet door. Although this design can reduce the integration degree of the appliance and the home, it also increases the thickness of the entire door body assembly. This results in that after the appliance is pushed into the cavity, relying only on the original single-axis or double-axis hinge, the door body assembly with the door panel may interfere with the side of the installation space body during the process of opening and closing the door, thus causing the door body assembly of the appliance to be unable to be normally opened or closed.

[0046] The following refers to Figure 1 , through specific embodiments and their application scenarios, the door body assembly and refrigeration equipment provided by the embodiments of the present utility model.

[0047] In the first aspect, as Figure 1As shown in the figure, an embodiment of the present utility model provides a door body assembly. The door body assembly includes a box door 10, a door panel 30, a driving assembly 40, a driven assembly 50, and a magnetic transmission mechanism. The box door 10 is rotatably connected to the electrical appliance main body 20 and is adapted to open or close the storage space of the electrical appliance main body 20. The door panel 30 is slidably disposed outside the box door 10. The driving assembly 40 and the driven assembly 50 are disposed on one of the box door 10 or the door panel 30, and the driven assembly 50 is connected to the other one. The magnetic transmission mechanism includes a moving magnetic member 62 and a fixed magnetic member 61. The fixed magnetic member 61 is located between the driving assembly 40 and the driven assembly 50 and is magnetically connected to the moving magnetic member 62. The driving assembly 40 is adapted to strike the fixed magnetic member 61 so that the moving magnetic member 62 moves in a direction away from the fixed magnetic member 61 to which it is magnetically connected, so that the moving magnetic member 62 drives the driven assembly 50 to move.

[0048] The box door 10 is a part of the electrical appliance main body 20 (such as a refrigerator) and is used to open or close the storage space of the electrical appliance main body 20. The box door 10 can be an object directly operated by the user, and the opening and closing of the storage space are controlled by rotation.

[0049] The door panel 30 is disposed outside the box door 10 and can slide along the box door 10. The user can open or close the box door 10 by pushing the door panel 30. The design of the door panel 30 can improve the overall appearance consistency and aesthetics, and the opening method by sliding instead of rotating can reduce the required space.

[0050] The driving assembly 40 is installed on one of the box door 10 or the door panel 30 and is used to generate power. It may be composed of a small motor or other types of actuators and is used to generate sufficient force to start the action of the magnetic transmission mechanism.

[0051] The driven assembly 50 is connected to another component (that is, the component on which the driving assembly 40 is not installed). Its main function is to receive the force transmitted by the magnetic transmission mechanism and convert it into the movement required by the door panel 30.

[0052] The magnetic transmission mechanism is the core part of this design. It transmits force through magnetic interaction to achieve non-contact power transmission.

[0053] At least a part of the moving magnetic member 62 is connected to the driven assembly 50 and moves together with the driven assembly 50.

[0054] The fixed magnetic member 61 is located between the driving assembly 40 and the driven assembly 50 and is magnetically connected to the moving magnetic member 62. When the driving assembly 40 strikes the fixed magnetic member 61, due to magnetic interaction, the moving magnetic member 62 will move in a direction opposite to the fixed magnetic member 61, thereby driving the driven assembly 50 and the door panel 30 to move.

[0055] When the user or an external mechanism (such as the sensor 70 detecting a door opening action) triggers the driving component 40, the driving component 40 starts to work. The driving component 40 impacts the fixed magnetic member 61. Due to the magnetic interaction, the moving magnetic member 62 will move in the direction opposite to that of the fixed magnetic member 61. The moving magnetic member 62 drives the driven component 50 to move, thereby driving the door panel 30 to move relative to the cabinet door 10. The magnetic transmission mechanism realizes non-contact power transmission, which can significantly reduce the wear between mechanical components, improve the reliability and service life of the system. And while ensuring that the door panel 30 can be normally closed, it avoids interference with the cabinet body around the refrigeration equipment, improving the overall user experience.

[0056] In this application, the driving component 40 is provided on one of the cabinet door 10 or the door panel 30, the driven component 50 is connected to the other. At the same time, the fixed magnetic member 61 of the magnetic transmission mechanism is located between the driving component 40 and the driven component 50 and is magnetically connected to the moving magnetic member 62. The driving component 40 is adapted to impact the fixed magnetic member 61 so that the moving magnetic member 62 moves in the direction away from the fixed magnetic member 61 to which it is magnetically connected, so that the moving magnetic member 62 drives the driven component 50 to move; when the user or an external mechanism (such as the sensor 70 detecting a door opening action) triggers the driving component 40, when the driving component 40 impacts the fixed magnetic member 61, due to the magnetic interaction, the moving magnetic member 62 will move in the direction opposite to that of the fixed magnetic member 61, thereby driving the driven component 50 to move, and then driving the door panel 30 to move relative to the cabinet door 10. While ensuring that the door panel 30 can be normally closed, it avoids interference between the door panel 30 and the cabinet body around the refrigeration equipment.

[0057] Furthermore, the door body assembly of the present utility model reduces mechanical wear and improves the reliability and service life of the system by using a non-contact magnetic transmission method.

[0058] Referring to Figure 1 , in some embodiments, the magnetic transmission mechanism includes a plurality of fixed magnetic members 61 and moving magnetic members 62 arranged in a straight line, and at least one moving magnetic member 62 is arranged between two adjacent fixed magnetic members 61.

[0059] It can be understood that in this embodiment, the fixed magnetic member 61 and the moving magnetic member 62 are arranged along a straight line to form a series of magnetic units. When the driving assembly 40 is activated, it strikes the first fixed magnetic member 61, causing magnetic interaction, which in turn causes the first moving magnetic member 62 adjacent to it to move. Subsequently, the moving magnetic member 62 will continue to push other moving magnetic members 62 along the straight line until it finally reaches the last moving magnetic member 62 connected to the driven assembly 50. This cascaded motion transmission method can achieve longer-distance motion and can precisely control the moving speed and position of the door panel 30. Thus, by setting multiple fixed magnetic members 61 and moving magnetic members 62, more precise motion control can be achieved, thereby improving the accuracy of the movement of the door panel 30.

[0060] Referring to Figure 1 , in some embodiments, the fixed magnetic member 61 is a magnet seat, and the moving magnetic member 62 is a magnet ball; the adjacent magnet seats are connected by a motion track 63, and the magnet seat is connected to the driven assembly 50 by the motion track 63.

[0061] It can be understood that the magnet seat, as the fixed magnetic member 61, is installed at one end close to the driving assembly 40. The magnet seat is a magnet made of a permanent magnetic material and has a fixed magnetic pole direction for interaction with the moving magnetic member 62.

[0062] The magnet ball, as the moving magnetic member 62, can move along a predetermined path and is connected to the driven assembly 50. The magnet ball is a small spherical magnet made of a permanent magnetic material and can roll or slide freely to move between the magnet seats.

[0063] The motion track 63 is used to guide the motion path of the magnet ball to ensure that the magnet ball can move accurately along the predetermined trajectory. The motion track 63 can be one or more tracks for connecting adjacent magnet seats and / or connecting the magnet seat to the driven assembly 50.

[0064] When the driving assembly 40 is triggered by a user or an external mechanism (such as the sensor 70 detecting an opening action), the driving assembly 40 starts to work. The driving assembly 40 strikes the first magnet seat. The magnetic interaction between the magnet seat and the magnet ball causes the magnet ball to move in the opposite direction to the magnet seat. The magnet ball moves along the motion track 63 and interacts with the subsequent magnet seats in sequence, forming a cascaded motion transmission until it finally reaches the last magnet ball connected to the driven assembly 50. The last magnet ball drives the driven assembly 50 to move, thereby driving the door panel 30 to move relative to the cabinet door 10. This embodiment uses magnet balls and magnet seats in combination with the motion track 63 to achieve very precise motion control.

[0065] Referring to Figure 1, in some embodiments, the driving component 40 includes an elastic member 41, and the elastic member 41 is adapted to switch between a compressed state and a popped state. In the popped state, the driving component 40 impacts the fixed magnetic member 61.

[0066] It can be understood that in the embodiments of the present application, the elastic member 41 is adapted to store energy and generate an impact force when released. When the elastic member 41 is in the compressed state, it stores energy. When the triggering condition is met (for example, triggered by a user or an external mechanism), the elastic member 41 quickly returns to its natural state or the popped state, thereby generating an impact force that causes the driving component 40 to impact the fixed magnetic member 61. Through the elastic member 41, the present application can efficiently store and release energy, making the impact process more reliable and controllable.

[0067] When the box door 10 is closed, the elastic member 41 is compressed and stores energy. When the driving component 40 is triggered by a user or an external mechanism (such as a sensor 70 detecting an opening action), the elastic member 41 releases the stored energy. The elastic member 41 quickly returns to its natural state or the popped state, causing the driving component 40 to impact the first magnet seat. The magnetic interaction between the magnet seat and the magnet ball causes the magnet ball to move in the direction opposite to the magnet seat. The magnet ball moves along the movement track 63 and interacts with the subsequent magnet seats in turn, forming a cascaded motion transfer until it finally reaches the last magnet ball connected to the driven component 50. The last magnet ball drives the driven component 50 to move, thereby driving the door panel 30 to move relative to the box door 10.

[0068] Optionally, the elastic member 41 can be a helical spring or a torsion spring, etc., which can be selected according to specific requirements.

[0069] Refer to Figure 1 , in some embodiments, the driving component 40 further includes a first magnetic member 42, and the first magnetic member 42 is connected to the first end of the elastic member 41. The second end of the elastic member 41 is fixed to the box door 10 or the door panel 30.

[0070] It can be understood that in this embodiment, the first magnetic member 42 is connected to the first end of the elastic member 41 and is used for magnetic interaction with the fixed magnetic member 61. When the elastic member 41 is in the compressed state, the first magnetic member 42 will also be compressed accordingly. When the elastic member 41 releases energy, the first magnetic member 42 will impact the fixed magnetic member 61, triggering a magnetic interaction. Through the interaction between the first magnetic member 42 and the fixed magnetic member 61 in this embodiment, very precise motion control can be achieved.

[0071] Refer to Figure 1 , in some embodiments, the driving component 40 further includes a reset member 43, and the reset member 43 is adapted to switch the elastic member 41 from the popped state to the compressed state.

[0072] It can be understood that in this embodiment, the reset member 43 is used to pull the elastic member 41 back from the ejected state to the compressed state after the elastic member 41 completes the impact action, so as to prepare for the next impact again. The reset member 43 can be a telescopic rod element, which will pull the elastic member 41 back to the initial compressed state after the elastic member 41 releases energy. In this embodiment, the automatic reset of the elastic member 41 can be achieved through the reset member 43 without additional manual intervention. The reset member 43 enables the elastic member 41 to quickly reset, supports continuous operation, and is suitable for application scenarios that require frequent door opening and closing.

[0073] Referring to Figure 1 , in some embodiments, the driven assembly 50 includes a connecting rod 51. The first end of the connecting rod 51 is adapted to be connected to the moving magnetic member 62 to enable the moving magnetic member 62 to drive the connecting rod 51 to move, and the second end of the connecting rod 51 is connected to the door panel 30 or the box door 10.

[0074] It can be understood that in this embodiment, the connecting rod 51, as a part of the driven assembly 50, is used to transmit the movement of the moving magnetic member 62 to the door panel 30 or the box door 10, thereby realizing the sliding of the door panel 30 relative to the box door 10. When the moving magnetic member 62 moves in the direction opposite to the fixed magnetic member 61, it drives the first end of the connecting rod 51 to move. The second end of the connecting rod 51 is connected to the door panel 30 or the box door 10, so the movement of the connecting rod 51 causes the door panel 30 to slide relative to the box door 10.

[0075] Referring to Figure 1 , in some embodiments, the driven assembly 50 further includes a second magnetic member 52. The first end of the connecting rod 51 is connected to the second magnetic member 52, and the second magnetic member 52 is adapted to be magnetically connected to the moving magnetic member 62, and the moving magnetic member 62 drives the connecting rod 51 to move through the second magnetic member 52.

[0076] It can be understood that in this embodiment, the second magnetic member 52, as a part of the driven assembly 50, is used to magnetically connect with the moving magnetic member 62, thereby transmitting the movement of the moving magnetic member 62 to the connecting rod 51. When the moving magnetic member 62 moves in the direction opposite to the fixed magnetic member 61, it magnetically interacts with the second magnetic member 52. This interaction causes the second magnetic member 52 to move, and then drives the first end of the connecting rod 51 to move. The second end of the connecting rod 51 is connected to the door panel 30 or the box door 10, so the movement of the connecting rod 51 causes the door panel 30 to slide relative to the box door 10.

[0077] Referring to Figure 1 , in some embodiments, the driven assembly 50 further includes a slider 53. The slider 53 is relatively fixed to the door panel 30 or the box door 10, and the slider 53 is provided at the second end of the connecting rod 51.

[0078] It can be understood that, in this embodiment, the slider 53 is used to ensure that the second end of the connecting rod 51 can move smoothly along a predetermined path, and also ensure that the door panel 30 or the box door 10 remains fixed relative to the slider 53. The slider 53 can move along a specific guide rail or groove to ensure that the second end of the connecting rod 51 can move along the expected direction, thereby driving the door panel 30 or the box door 10 to slide.

[0079] When the door 10 assembly is closed, the elastic member 41 is compressed and the first magnetic member 42 moves to a predetermined position. When the user or an external mechanism (such as the sensor 70 detecting the door opening action) triggers the drive assembly 40, the elastic member 41 releases the stored energy. The elastic member 41 quickly returns to the natural state or the pop-up state, and the first magnetic member 42 hits the first magnet seat. The magnetic interaction between the magnet seat and the first magnetic member 42 causes the magnetic ball to move in the opposite direction of the magnet seat. The magnetic ball moves along the motion track 63, interacting with the subsequent magnet seats in turn, forming a cascade motion transmission until it finally reaches the last magnetic ball connected to the driven assembly 50. The last magnetic ball drives the second magnetic member 52 to move, and then drives the first end of the connecting rod 51 to move. The second end of the connecting rod 51 is connected to the door panel 30 or the door 10 through the slider 53, and the slider 53 moves along the predetermined path, thereby driving the door panel 30 to move relative to the door 10. After the elastic member 41 completes the impact action, the reset member 43 pulls the elastic member 41 back to the compressed state to prepare for the next impact.

[0080] Reference Figure 1 In some embodiments, the door body assembly further includes a shielding shell, forming a track cavity 31 , and the driving assembly 40 , the magnetic transmission mechanism and the driven assembly 50 are arranged in sequence along the extension direction of the track cavity 31 .

[0081] It is understood that in this embodiment, the shielding shell is used to protect the internal drive assembly 40, magnetic transmission mechanism and driven assembly 50, prevent external factors (such as dust, moisture) from damaging the components, and reduce electromagnetic interference. The shielding shell forms a closed space, and a track cavity 31 is provided inside, so that the drive assembly 40, the magnetic transmission mechanism and the driven assembly 50 can be arranged and moved in an orderly manner according to a predetermined path. The design of the track cavity 31 ensures that all components can move smoothly along the predetermined path, thereby achieving very precise sliding control of the door panel 30.

[0082] Reference Figure 1 In some embodiments, the door assembly further includes a sensor 70, which is suitable for detecting the movement of the door assembly relative to the electrical appliance body 20. The sensor 70 is connected to the drive assembly 40 and controls the movement of the drive assembly 40 based on the movement state of the door assembly relative to the electrical appliance body 20.

[0083] It can be understood that, in this embodiment, the sensor 70 is used to detect the opening and closing angle of the door assembly relative to the appliance body 20, such as the degree of opening or closing.

[0084] In the present application, the sensor 70 is an angle sensor 70, which can monitor the position change of the door assembly and transmit the signal to the control system. The sensor 70 is connected to the drive assembly 40, and can control the movement of the drive assembly 40 according to the opening and closing angle of the door assembly. For example, when the door assembly is opened to a certain extent, the sensor 70 can send a signal to stop the action of the drive assembly 40, or when the door assembly needs to be closed, the sensor 70 can trigger the drive assembly 40 to start working. In this way, through the setting of the sensor 70, very precise door assembly position control can be achieved.

[0085] In a specific embodiment, the sensor 70 is an angle sensor 70. When the outside world wants to open the door, α>0° is satisfied. The main control board 80 receives the sensor 70 signal and transmits the signal to the driving component 40. The elastic member 41 and the first magnetic member 42 are instantly ejected and hit the first magnet seat. The magnetic interaction between the magnet seat and the magnetic ball causes the magnetic ball to move in the opposite direction of the magnet seat. The magnetic ball moves along the motion track 63 and interacts with the subsequent magnet seats in turn to form a cascade motion transmission until it finally reaches the last magnetic ball connected to the driven component 50. The last magnetic ball moves parallel to the slider 53 connected to it through the connecting rod 51, so that the door panel 30 and the box door 10 are relatively translated at the moment of opening the door, so that the door panel 30 and the door body of the box door 10 are staggered to ensure that the door opening does not interfere. The whole process takes place in the track cavity 31, using the magnetic coupling mechanism 60 powered by magnets. When the first magnetic part 42 hits the left side of the first magnet seat, the law of conservation of energy is satisfied, and the magnet seat changes the movement trajectory of the magnetic ball, so that it is attracted and accelerated forward when it approaches the magnet seat. This acceleration increases the impact force, and the magnetic ball is quickly ejected when the attraction of the magnet seat is weakest. The movement time of this process is very short and the force is large enough to achieve the translation of the door panel 30 and the box door 10 in an instant. The drive component 40 will reset immediately after working, and when the outside world gives the door closing action, the second magnetic part 52 will return to its original position along the track. When there is another door opening action, the above working process is repeated.
