[0041] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0042] Reference below Figure 1-Figure 3 The door structure provided in an embodiment of the present application is described. The door structure is applied to a storage device and includes a door body 100 , a first magnetic member 200 , a door seal 300 , a second magnetic member 400 and a switch 500 .

[0043] It should be noted that the door structure can be applied to a variety of storage equipment with refrigeration function, such as refrigerators, freezers, display cabinets, beverage cabinets, wine cabinets, cold cabinets and refrigerated vending machines. The door structure has various forms and a wide range of applications.

[0044] The door body 100 is used to be installed on a cabinet of a storage device, and the first magnetic member 200 is provided on the door body 100. The material of the door body 100 includes but is not limited to hard plastic, stainless steel, aluminum alloy or titanium alloy.

[0045] It can be understood that one side of the door body 100 is pivotally connected to the cabinet body so that the other side of the door body 100 can selectively abut against the cabinet body, thereby realizing that the door body 100 has two states of opening and closing.

[0046] The door seal 300 is mounted on the door 100 to seal against the cabinet opening. The door seal 300 is provided with a second magnetic member 400. The door seal 300 can be made of a relatively elastic material, such as rubber. The connection between the door seal 300 and the door 100 may be achieved by, but is not limited to, gluing.

[0047] The switch 500 is connected to at least one of the first magnetic member 200 and the second magnetic member 400 . When the switch 500 is turned on, it is configured to generate a magnetic force between the first magnetic member 200 and the second magnetic member 400 to displace the second magnetic member 400 , thereby deforming the door seal 300 .

[0048] It can be understood that, on the one hand, the door seal 300 is used to achieve a sealed connection between the door body 100 and the cabinet body when it is closed, so as to ensure that the temperature inside the cabinet is maintained at a lower temperature, thereby extending the storage time of the items placed in the cabinet. On the other hand, considering that the air pressure inside the cabinet is much lower than the air pressure outside the cabinet when the door body 100 is closed, when the door body 100 needs to be opened, the switch 500 is used to generate a magnetic force between the first magnetic part 200 and the second magnetic part 400 to displace the second magnetic part 400, thereby causing the part of the door seal 300 where the second magnetic part 400 is provided to deform, resulting in an airway formed between the door body 100 and the cabinet door at the deformation point of the door seal 300, that is, the air inside the cabinet and the air outside the cabinet can flow through the airway, which balances the air pressure inside and outside the cabinet, reduces the difficulty of users opening the door, and improves the user experience.

[0049] According to the door structure provided in the embodiment of the present application, a first magnetic part 200 is provided on the door body 100, a second magnetic part 400 is provided on the door seal 300, and a magnetic force is generated between the first magnetic part 200 and the second magnetic part 400 through the switch 500 to displace the second magnetic part 400, thereby deforming the door seal 300, balancing the air pressure inside and outside the cabinet when the door body 100 is opened, reducing the difficulty of users opening the door and improving the user experience.

[0050] In some embodiments, as Figures 1 to 3 As shown, a mounting portion 600 is provided on the side of the door seal 300 facing the cabinet, and the second magnetic member 400 is mounted within the mounting portion 600. When the switch 500 is turned on, it is configured to generate an attractive force between the first magnetic member 200 and the second magnetic member 400. The connection between the second magnetic member 400 and the mounting portion 600 includes, but is not limited to, bonding. It should be noted that the specific shape and size of the mounting portion 600 can be designed according to actual needs and is not specifically limited in this embodiment.

[0051] It can be understood that by arranging the mounting portion 600 on the side of the door seal 300 close to the cabinet body, the door seal 300 has deformation conditions and can form an airway between the cabinet body and the cabinet door, thereby ensuring that when the door body 100 needs to be opened, the attraction generated by the switch 500 can move the second magnetic part 400 to a position close to the door body 100, thereby driving the door seal 300 to deform and the side of the door seal 300 close to the cabinet body close to the cabinet door, that is, there is a gap between the side of the door seal 300 close to the cabinet body and the cabinet body, and the airway includes the gap to ensure that the internal and external gases of the cabinet can be exchanged, thereby achieving the effect of balancing the air pressure inside and outside the cabinet.

[0052] In this embodiment, Figure 3 As shown, the mounting portion 600 has a mounting groove extending along the length of the door seal 300, and the second magnetic member 400 is placed in the mounting groove, which not only reduces weight but also reduces assembly complexity. It should be noted that the size and shape of the mounting groove can be designed based on the size and shape of the second magnetic member 400, and this embodiment does not impose specific limitations on this.

[0053] In some embodiments, as Figure 3 As shown, a portion of the mounting portion 600's wall surface protrudes inward from the surface of the door seal 300 facing the cabinet; another portion of the mounting portion 600's wall surface protrudes outward from the surface of the door seal 300 facing the cabinet, and the wall surface of the mounting portion 600 is connected to the surface of the door seal 300 facing the cabinet. It should be noted that the cross-section of the mounting portion 600 includes, but is not limited to, oval, circular, or rectangular shapes. The specific shape and size of the mounting portion 600 can be designed according to actual needs and is not specifically limited in this embodiment.

[0054] It can be understood that when the door body 100 is closed, the mounting portion 600 protrudes outward from the surface of the door seal 300 facing the cabinet and abuts against the cabinet surface to seal the cabinet opening. When the door body 100 needs to be opened, the attraction causes the second magnetic part 400 to drive the mounting portion 600 as a whole to move away from the cabinet. At the same time, based on the wall surface of the mounting portion 600 being connected to the surface of the door seal 300 facing the cabinet, the mounting portion 600 drives the part of the door seal 300 connected to the mounting portion 600 away from the cabinet surface, thereby realizing the deformation of the door seal 300 to form an airway.

[0055] In this embodiment, in order to ensure the stability of the structure, the mounting portion 600 and the door seal 300 can be integrally formed by injection molding or other methods.

[0056] In some embodiments, as Figure 3 As shown, the door seal 300 is provided with a deformation cavity 310, and a support portion 320 is provided in the deformation cavity 310, and the mounting portion 600 is used to move in the direction where the support portion 320 is located. In this embodiment, Figure 3As shown, the deformation cavity 310 is provided along the length of the door seal 300, which not only reduces weight but also reduces processing costs. It should be noted that the size and shape of the deformation cavity 310 and the support portion 320 can be designed according to actual needs and are not specifically limited in this embodiment.

[0057] It is understood that, along the direction approaching the cabinet door, a support portion 320 located within the deformation cavity 310 and a second magnetic member 400 located within the mounting groove are sequentially provided between the door body 100 and the cabinet door. When the door body 100 needs to be opened, the attraction causes the second magnetic member 400 to drive the mounting portion 600 as a whole closer to the support portion 320, while simultaneously changing the cross-sectional shape of the deformation cavity 310 so that the mounting portion 600 can be moved away from the cabinet to form an airway. In addition, because the support portion 320 is located within the deformation cavity 310 and between the door body 100 and the mounting portion 600, the deformation range of the deformation cavity 310 can be limited, preventing the occurrence of severe deformation that cannot be restored, thereby affecting the sealing of the energy storage device.

[0058] In this embodiment, Figure 3 As shown, the support portion 320 has a bottom plate 321 and two side plates 322 that are opposite and respectively arranged on both sides of the bottom plate 321. The side plates 322, the bottom plate 321 and the door seal 300 are arranged to divide the deformation cavity 310 into a support space and a deformation space that are not connected to each other. That is, when the attraction causes the second magnetic part 400 to drive the mounting portion 600 as a whole to approach the support portion 320, on the one hand, the cross-section of the deformation space in the deformation cavity 310 is changed to form an airway, and on the other hand, the deformation range of the deformation space is limited by the support space, that is, when the mounting portion 600 and the bottom plate 321 are abutted, the door seal 300 is in the state of maximum deformation.

[0059] Furthermore, if Figure 3 As shown, the distance between the two side panels 322 gradually decreases in the direction approaching the cabinet body, so as to further improve the supporting effect of the sealing strip.

[0060] In some embodiments, as Figure 3 As shown, two guide portions 330 are disposed opposite each other within the deformation cavity 310. The two guide portions 330 are connected to the two ends of the support portion 320 at obtuse angles, and the mounting portion 600 is located between the two guide portions 330. It should be noted that the shape of the guide portions 330 and the specific size of the obtuse angle formed between the guide portions 330 and the support portion 320 can be designed according to actual needs and are not specifically limited in this embodiment.

[0061] It can be understood that the guide portion 330 and the side panel 322 correspond one to one, one end of the guide portion 330 is installed at the connection between the bottom plate 321 and the corresponding side panel 322 and forms an obtuse angle with the side of the bottom plate 321 close to the cabinet, and the mounting portion 600 is located between the two guide portions 330. It not only plays a guiding role when the second magnetic part 400 drives the mounting portion 600 to move close to the bottom plate 321, but also plays a role in avoiding the mounting portion 600, so as to avoid the mounting portion 600 from contacting the guide portion 330 during the movement, thereby limiting the mounting portion 600 from continuing to approach the bottom plate 321.

[0062] In some embodiments, as Figure 3 As shown, the guide portion 330 includes a first section 331 and a second section 332, one end of the first section 331 is connected to the support portion 320 and forms a first angle; one end of the second section 332 is connected to the other end of the first section 331 and forms a second angle, and the second angle is greater than the first angle.

[0063] It can be understood that one end of the first section 331 is installed at the connection between the bottom plate 321 and the side plate 322 and forms a first obtuse angle with the side of the bottom plate 321 close to the cabinet body, and one end of the second section 332 is connected to the other end of the first section 331 and forms a second obtuse angle with the side of the first section 331 close to the side plate 322. Since the second obtuse angle is greater than the first obtuse angle, the two second sections 332 can limit the second magnetic part 400 to move only from between the two second sections 332 to the bottom plate 321, and by enabling the two first sections 331 to simultaneously abut against the wall of the mounting portion 600 to limit the deformation degree of the deformation cavity 310.

[0064] In some embodiments, considering that one side of the door body 100 is pivotally connected to the cabinet body, the first magnetic member 200 may be disposed on at least one of the other three sides of the door body 100 .

[0065] In some embodiments, there are multiple ways to configure the switch 500 to generate a magnetic force between the first magnetic member 200 and the second magnetic member 400 when turned on, which causes the second magnetic member 400 to move. Detailed descriptions are given below from three different implementation perspectives.

[0066] 1. As Figure 3As shown, the switch 500 includes a fixed portion 510 and an operating portion 520, wherein the fixed portion 510 is mounted on the door body 100, and the operating portion 520 is movably mounted on the fixed portion 510 at one end away from the cabinet; the first magnetic member 200 includes an adjusting portion 210 and a matching portion 220, wherein the adjusting portion 210 is mounted on one end of the operating portion 520 close to the cabinet; the matching portion 220 is mounted on the fixed portion 510, and generates a variable magnetic force between the adjusting portion 210 and the adjusting portion 210 under the movement of the adjusting portion 210. It should be noted that the respective materials of the fixed member, the operating portion 520 and the adjusting portion 210 include but are not limited to hard plastic, stainless steel, aluminum alloy or titanium alloy. The connection method between the fixed member and the door body 100, the connection method between the adjusting portion 210 and the operating portion 520, and the connection method between the matching portion 220 and the fixed portion 510 are but are not limited to welding, threaded connection and clamping.

[0067] It can be understood that the pressure at which the door seal 300 is deformed to generate an airway is N. When the door body 100 is closed, the adjusting part 210 is in the first position, and a first magnetic force F1 is generated between the adjusting part 210 and the matching part 220, F1<N, that is, the second magnetic part 400 cannot drive the door seal 300 to deform, so as to ensure the sealing of the cabinet opening; when the door body 100 needs to be opened, the adjusting part 210 is driven to the second position by the operating part 520, so that a second magnetic force F2 is generated between the adjusting part 210 and the matching part 220, F2≥N, that is, the second magnetic part 400 drives the door seal 300 to deform, so as to form an airway to balance the air pressure inside and outside the cabinet, thereby facilitating the opening of the door body 100.

[0068] In some embodiments, the adjustment portion 210 includes a first magnetic region and a second magnetic region spaced apart and having opposite magnetic poles, with the first magnetic region and the second magnetic region having opposite magnetic poles. The mating portion 220 includes a third magnetic region, with the first and third magnetic regions having the same magnetic poles. When the device is turned on, the first and third magnetic regions are magnetically connected to generate a magnetic attraction. The adjustment portion 210 and the mating portion 220 are made of a hard magnetic material such as a neodymium iron boron magnet, while the second magnetic member 400 can be made of a soft magnetic material such as iron, steel, or steel.

[0069] It can be understood that one of the first magnetic region and the second magnetic region is an N pole, the other of the first magnetic region and the second magnetic region is an S pole, and the matching portion 220 also has a fourth magnetic region opposite to the magnetic pole of the third magnetic region, that is, when the door body 100 needs to be opened, the first magnetic region of the adjusting portion 210 and the third magnetic region of the matching portion 220 are directly opposite, that is, the N poles of the adjusting portion 210 and the matching portion 220 correspond to each other, and the S poles of the adjusting portion 210 and the matching portion 220 correspond to each other, so that the magnetic force F2 generated by the first magnetic member 200 is the adjusting force F2. The sum of the magnetic forces of the adjusting part 210 and the matching part 220 is added together, thereby generating a magnetic attraction force on the second magnetic part 400 to move the second magnetic part 400 closer to and away from the cabinet; when the door body 100 is closed, the second magnetic area of ​​the adjusting part 210 and the third magnetic area of ​​the matching part 220 are opposite to each other, that is, the N pole of the adjusting part 210 corresponds to the S pole of the matching part 220, and the S pole of the adjusting part 210 corresponds to the N pole of the matching part 220, so that the magnetic force F1 generated by the first magnetic part 200 is the difference between the magnetic forces of the adjusting part 210 and the matching part 220.

[0070] In some embodiments, as Figure 3 As shown, the projection of the third magnetic region on the door seal 300 and the projection of the second magnetic member 400 on the door seal 300 at least partially overlap.

[0071] It is understood that by ensuring that the projection of the third magnetic region on the door seal 300 at least partially overlaps with the projection of the second magnetic member 400 on the door seal 300, the magnetic attraction generated by the first magnetic member 200 is directly directed toward the second magnetic member 400, maximizing the effect on the second magnetic member 400 and achieving rapid deformation of the door seal 300. In this embodiment, the projection of the third magnetic region on the door seal 300 is completely within the projection of the second magnetic member 400 on the door seal 300.

[0072] In some embodiments, as Figure 3 As shown, the operating portion 520 is rotatably disposed on the fixing portion 510 , and the direction of the rotation axis of the operating portion 520 is parallel to the direction approaching the cabinet.

[0073] It is understandable that the user can rotate the operating portion 520 to rotate the adjusting portion 210 from the first position to the second position, which is simple to operate and saves space.

[0074] In this embodiment, Figure 3 As shown, the fixing portion 510 forms an open accommodating cavity, the matching portion 220 is installed in the accommodating cavity, and the operating portion 520 includes a connected knob and a rotating rod. The knob is rotatably installed at the opening for the user to operate. The rotating rod is located in the accommodating cavity and its two ends are respectively connected to the knob and the adjusting portion 210.

[0075] In this embodiment, Figure 3 As shown, the mating portion 220 defines a mating groove 221. The mating groove 221 and the adjusting portion 210 are plugged into each other so that at least a portion of the outer wall of the adjusting portion 210 abuts against the inner wall of the mating groove 221. This means that the first and second magnetic regions are spaced apart in a circular pattern. This not only further saves space but also provides enhanced support for the switch 500. It should be noted that the shapes of the adjusting portion 210 and the mating groove 221 include, but are not limited to, cylindrical shapes.

[0076] In some other embodiments, the operating portion 520 may also be movably disposed on the door body 100 , and the moving direction of the operating portion 520 is parallel to the length direction of the door seal 300 .

[0077] It can be understood that the user can move the operating part 520 on the fixed seat to move the adjustment part 210 from the first position to the second position, that is, the first magnetic area and the second magnetic area are spaced apart along the length direction of the door seal 300, and the operating part 520 can also be movably installed on the fixed part 510 while the first magnetic part 200 generates a variable magnetic force.

[0078] In some embodiments, as Figure 3 As shown, the switch 500 further includes an elastic member 530, one end of which is mounted on at least one of the operating portion 520 or the adjusting portion 210, and the other end of which is mounted on the fixing portion 510, for driving the operating portion 520 to reset. The elastic member 530 includes but is not limited to a spring.

[0079] It is understood that when the user moves the adjustment portion 210 from the first position to the second position via the operating portion 520, the elastic member 530 simultaneously deforms. When the user leaves the operating portion 520, the external force applied to the operating portion 520 disappears, and the elastic member 530's own rebound force drives the corresponding operating portion 520 and the adjustment portion 210 to move in opposite directions until the adjustment portion 210 returns from the second position to the first position, thereby ensuring the sealing of the cabinet opening when the door 100 is closed. In this embodiment, the elastic member 530 is sleeved outside the rotating rod, and the ends of the elastic member 530 are respectively connected to the rotating rod and the accommodating cavity to limit the deformation direction of the elastic member 530.

[0080] In some embodiments, the switch 500 further includes a limiter mounted on the fixing seat to limit the range of movement of the adjustment portion 210 .

[0081] It is understandable that, given that the user cannot accurately control the degree of force applied when operating the operating portion 520, a limiter is provided to serve as a reminder to the user, allowing the user to quickly determine whether the adjustment portion 210 is currently in the second position, further improving the user experience. In this embodiment, when the adjustment portion 210 is in the first position, the limiter is not in contact with either the adjustment portion 210 or the operating portion 520. When the adjustment portion 210 is in the second position, the limiter abuts at least one of the adjustment portion 210 and the operating portion 520, thereby limiting the range of motion of the adjustment portion 210.

[0082] Second, the first magnetic member 200 is an electromagnet or an electromagnetic coil, the second magnetic member 400 is a permanent magnet, the switch 500 includes an electromagnetic switch 500, and the controller is connected to the first magnetic member 200 to control the on and off of the current applied to the first magnetic member 200.

[0083] It is understandable that the user can turn on the electromagnetic switch 500 to energize the first magnetic part 200, thereby generating an attractive force between the first magnetic part 200 and the second magnetic part 400, thereby driving the second magnetic part 400 to approach the first magnetic part 200 and away from the cabinet body, so that the door seal 300 is deformed when it is open; when the door body 100 needs to be closed, the user only needs to turn off the electromagnetic switch 500 to lose the attractive force between the first magnetic part 200 and the second magnetic part 400, and the door seal 300 returns to its original shape under the action of its own elastic force to ensure the sealing of the cabinet opening.

[0084] Third, the first magnetic member 200 is an electromagnet or an electromagnetic coil, the second magnetic member 400 is a permanent magnet, the switch 500 includes an electromagnetic switch 500 , and the controller is connected to the first magnetic member 200 to control the direction of the current applied to the first magnetic member 200 .

[0085] It is understandable that the user can control the current passing through the first magnetic part 200 to be in a first direction through the electromagnetic switch 500, so that an attraction force is generated between the first magnetic part 200 and the second magnetic part 400, thereby driving the second magnetic part 400 to approach the first magnetic part 200 and away from the cabinet body, so that the door seal 300 is deformed when it is open; when the door body 100 needs to be closed, the user can control the current passing through the first magnetic part 200 to be in a second direction opposite to the first direction through the electromagnetic switch 500, so that a repulsive force is generated between the first magnetic part 200 and the second magnetic part 400, thereby driving the second magnetic part 400 away from the first magnetic part 200 and close to the cabinet body, so that the door seal 300 fits tightly with the cabinet body under the action of the repulsive force, thereby ensuring the sealing of the cabinet opening.

[0086] In some embodiments, as Figure 3As shown, the door structure also includes a door handle 700, which is mounted on the door body 100. The switch 500 is mounted on the door handle 700, thereby further facilitating user operation and improving the user experience.
