[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] In the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0026] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0027] In the description of the embodiments of the present utility model, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "includes a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0028] Please refer to Figure 1 , Figure 1 The present invention is a schematic structural diagram of a specific implementation of the off-axis door assembly provided by the present invention.

[0029] like Figure 1 As shown, the embodiment of the utility model provides an off-axis door assembly, including a door leaf 100 and a door frame 200. The door frame 200 is fixedly mounted on a wall, and the door leaf 100 is hingedly assembled on the door frame 200, so that the door leaf 100 can rotate relative to the door frame 200, thereby realizing the opening or closing of the off-axis door assembly.

[0030] Specifically, the upper end of the door leaf 100 may be connected to the zenith axis 130, and the lower end of the door leaf 100 may be connected to the ground axis 140, and the zenith axis 130 and the ground axis 140 may be basically coaxially arranged; the upper part of the door frame 200 may be provided with a top seat 230, and the lower part of the door frame 200 may be provided with a base 240, the zenith axis 130 may be inserted into the top seat 230, and may rotate relative to the top seat 230, and the ground axis 140 may be inserted into the base 240, and may rotate relative to the base 240; in this way, through the cooperation of the zenith axis 130 and the top seat 230, and the cooperation of the ground axis 140 and the base 240, the door leaf 100 may be opened and closed relative to the door frame 200. The specific structural forms of the top seat 230 and the base 240 can be referred to the relevant technology, and are not limited here.

[0031] The central axis of the celestial axis 130 and the terrestrial axis 140 can constitute the rotation centerline X of the door leaf 100. Different from the conventional door assembly, in the embodiment of the utility model, the rotation centerline X of the door leaf 100 is not located at the lateral end of the door leaf 100, nor at the lateral middle of the door leaf 100, but at the area between the lateral end and the lateral middle, so that an off-axis design can be formed.

[0032] Among the four fan corners 150 of the door leaf 100, at least some of the fan corners 150 can be set as smooth fan corners, such as arc-shaped fan corners, etc., to reduce the number of sharp positions on the door leaf 100. In this way, during the opening and closing process of the door leaf 100, even if it collides with a collision object such as a human body or other parts due to an accident, the collision damage of the door leaf 100 and the collision object can be reduced. In addition, the structural aesthetics of the door leaf 100 can also be improved, which is conducive to improving the market competitiveness of the off-axis door assembly provided by the embodiment of the utility model.

[0033] The above-mentioned smooth corner portions can be formed by providing smooth connectors, such as arc connectors, at the corresponding corner portions 150 of the door leaf 100, so as to form a covering of a specific shape at the corresponding corner portions 150, thereby controlling the shape of the corresponding corner portions 150. The number of smooth corner portions can be set as required; Figure 1 In the implementation method, the four fan corners 150 of the door leaf 100 can all be set as smooth fan corners; and in some other implementation methods of the embodiment of the utility model, only part of the four fan corners 150 of the door leaf 100 can be set as smooth fan corners, and the other fan corners can still be conventional right-angled fan corners or non-smooth transition fan corners of other shapes.

[0034] In line with the door leaf 100, the door frame 200 may have four frame corners 250, and the structural forms of the four frame corners 250 may be substantially consistent with the corresponding fan corners 150. That is, when the fan corners 150 are smooth corners, the frame corners 250 may also be smooth corners, and when the fan corners 150 are right-angled corners, the frame corners 250 may also be right-angled corners; in this way, the door leaf 100 and the door frame 200 may have a better matching effect.

[0035] As described in the background technology section, in conventional solutions, there is a lack of effective sealing structure between the door leaf and the door frame of the eccentric door assembly, resulting in poor sealing performance of the eccentric door assembly, which in turn affects its sound insulation, heat insulation and other properties, and is not conducive to the promotion and application of the eccentric door assembly.

[0036] In view of this, in the embodiment of the utility model, the eccentric door assembly also includes a first sealing component 120 and an inflation and deflation component 300; the inflation and deflation component 300 is connected to the first sealing component 120, and the inflation and deflation component 300 is configured to be able to inflate or deflate the first sealing component 120, so that the first sealing component 120 can be switched between a bulging state and a deflated state. When the first sealing component 120 is in a bulging state, the volume of the first sealing component 120 can be increased, and the joint of the door leaf 100 and the door frame 200 can be effectively sealed, which can improve the sound insulation, heat insulation and other performances of the eccentric door assembly, and thus can improve the user experience, which is conducive to the promotion and application of the eccentric door assembly. When the first sealing component 120 is in a deflated state, the volume of the first sealing component 120 can be reduced, the joint of the door leaf 100 and the door frame 200 is no longer tight, and the rotation of the door leaf 100 relative to the door frame 200 can be conveniently realized so as to open the door leaf 100.

[0037] exist Figure 1 In the implementation mode, the first sealing component 120 is provided on the door leaf 100, and correspondingly, the inflation and deflation component 300 can also be provided on the door leaf 100, so as to be connected with the first sealing component 120 provided on the door leaf 100. In some other implementation modes of the embodiment of the utility model, the first sealing component 120 can also be provided on the door frame 200, in which case, the corresponding inflation and deflation component 300 can also be provided on the door frame 200, so as to be connected with the first sealing component 120 provided on the door frame 200; or, the door leaf 100 and the door frame 200 can also be provided with the first sealing component 120, in which case, the door leaf 100 and the door frame 200 can also be provided with the inflation and deflation component 300, so as to be used in conjunction with the first sealing component 120 provided on the door leaf 100 and the door frame 200.

[0038] Please refer to Figure 2 , Figure 2 It is a connection structure diagram of the inflation and deflation component and the first sealing component.

[0039] like Figure 2 As shown, in a specific example, the inflation and deflation component 300 may include a pump body 310 and an exhaust switch 370. The pump body 310 may be connected to the first sealing component 120 to inflate the first sealing component 120 so as to switch the first sealing component 120 to a bulging state. The exhaust switch 370 may also be connected to the first sealing component 120 to exhaust the first sealing component 120 so as to switch the first sealing component 120 to a deflated state.

[0040] Furthermore, the inflation and deflation component 300 may also include a pressure detection component 340 . The pressure detection component 340 may also be connected to the first sealing component 120 to detect the pressure inside the first sealing component 120 .

[0041] The setting of the pressure detection component 340 can better cooperate with the pump body 310 and the exhaust switch 370. Specifically, during the process of inflating the first sealing component 120, the pressure detection component 340 can detect the real-time pressure in the first sealing component 120 to determine the end point of inflation, which can better avoid the problem of poor sealing performance caused by insufficient inflation, and at the same time, it can also better avoid safety problems such as explosion of the first sealing component 120 caused by excessive inflation; during the process of exhausting the first sealing component 120, the pressure detection component 340 can also detect the real-time pressure in the first sealing component 120 to determine the end point of exhaust, which can better avoid the problem of difficulty in opening the door leaf 100 caused by insufficient exhaust.

[0042] Furthermore, the above-mentioned inflation and deflation component 300 can also include a power supply 320, a main switch 330, a control switch 350 and a voltage transformer component 360. These components cooperate with the aforementioned pump body 310, exhaust switch 370 and pressure detection component 340 to form an inflation and deflation component 300 with a high degree of automation.

[0043] Specifically, the power supply 320 can be connected to the pump body 310, the exhaust switch 370, the pressure detection component 340, the control switch 350 and the voltage conversion component 360, and can supply power to these components. The voltage conversion component 360 is arranged between the power supply 320 and the control switch 350, and can adjust the power supply voltage of the power supply 320 to the control switch 350; for example, the power supply 320 can provide a voltage of 24V, which can directly supply power to the pump body 310, the pressure detection component 340 and the exhaust switch 370. After the voltage conversion component 360 acts, the voltage supplied by the power supply 320 to the control switch 350 can be adjusted to 5V, so as to meet the use requirements of the control switch 350. The control switch 350 can be connected to the pump body 310 and the exhaust switch 370, and is used to control the start and stop of the pump body 310 and the exhaust switch 370. The main switch 330 is used to control whether the entire inflation and deflation component 300 is put into use. When the main switch 330 is in the disconnected state, the inflation and deflation component 300 cannot be used. When the main switch 330 is in the closed state, the inflation and deflation component 300 can be automatically put into operation with the cooperation of the aforementioned components.

[0044] It should be understood that the above description of the specific structure of the gas-charging and discharging component 300 is only an exemplary description of the embodiment of the utility model, and it cannot be used as a limitation on the scope of implementation of the eccentric door assembly provided by the utility model. Under the condition of satisfying the function, the gas-charging and discharging component 300 can also adopt other structural forms. For example, the gas-charging and discharging component 300 can also be a manually controlled component, so as to control the aforementioned pump body 310 and exhaust switch 370 to work by manual control. In this case, the structural form of the gas-charging and discharging component 300 can be relatively simple and low in cost.

[0045] Please refer to Figure 3 and Figure 4 , Figure 3 is a partial view of the joint between the door leaf and the door frame, wherein the first sealing component is in a deflated state. Figure 4 It is a partial view of the joint between the door leaf and the door frame, wherein the first sealing component is in a bulging state.

[0046] like Figure 3 and Figure 4 As shown, in the embodiment of the present utility model, the door leaf 100 may include a leaf body 110 , and the leaf body 110 may include a door panel main body portion 111 and a frame portion 112 .

[0047] The door panel body 111 is the main structure of the fan body 110. In some implementations, the door panel body 111 can be made of an insulation board to improve the overall thermal insulation performance of the fan body 110. In other implementations, the door panel body 111 can also be made of a common board.

[0048] The frame portion 112 may be located at the outer edge of the door panel body portion 111, and is used to cover the outer edge of the door panel body portion 111. In the implementation mode in which the door leaf 100 is provided with the first sealing component 120, the first sealing component 120 may be provided at the frame portion 112, and may be located at a side of the frame portion 112 away from the door panel body portion 111, so as to cooperate with the door frame 200.

[0049] Along the normal direction of the door leaf 100, that is Figure 3 and Figure 4 In the up and down directions, the frame portion 112 may be provided with at least one first heat insulation structure 113 to improve the thermal insulation performance of the door leaf 100 at the frame portion 112 .

[0050] Here, the embodiment of the utility model does not limit the specific structural form of the first thermal insulation structure 113. In practical applications, those skilled in the art can select according to specific circumstances, as long as it can meet the requirements of use. For example, the first thermal insulation structure 113 can be a thermal insulation board, thermal insulation filler, etc.

[0051] In a specific example, Figure 3 and Figure 4 As shown, the first heat insulation structure 113 may include two first heat insulation strips 113a and a first heat insulation material 113b; the two first heat insulation strips 113a may be arranged at intervals, and the direction in which the two first heat insulation strips 113a are arranged at intervals may be perpendicular to the normal direction of the door leaf 100, so as to Figure 3 and Figure 4 The orientation and position relationship in is used as a reference, that is, the two first thermal insulation strips 113a can be arranged at intervals along the left-right direction; the first thermal insulation material 113b can be filled between the two first thermal insulation strips 113a, and the two first thermal insulation strips 113a can well limit the first thermal insulation material 113b to reduce the possibility of movement of the first thermal insulation material 113b.

[0052] The first heat-insulating strip 113a is preferably made of composite materials, such as nylon, polyvinylchloride (PVC) alloy, etc., so as to provide higher strength performance while ensuring the heat-insulating effect. Since the first heat-insulating material 113b is arranged between the two first heat-insulating strips 113a, its type may not be too limited, as long as it can meet the heat-insulating requirements; for example, glass wool, rock wool, polyurethane foam, polystyrene board, silicate board, aerogel, etc. may be used.

[0053] The frame portion 112 may include a first substrate portion 112a and two first sealing plate portions 112b. The two first sealing plate portions 112b may be arranged at intervals along the normal direction of the door leaf 100, and the first substrate portion 112a may be arranged between the two first sealing plate portions 112b. The first substrate portion 112a and the first sealing plate portion 112b may both be made of metal to ensure the structural strength of the frame portion 112. The metal material may be, for example, a lightweight metal such as aluminum alloy, which may also effectively reduce the weight of the frame portion 112. A first heat insulation structure 113 may be arranged between the first substrate portion 112a and the two first sealing plate portions 112b. In this way, two first heat insulation structures 113 may be arranged in the frame portion 112, and the frame portion 112 may have a "double broken bridge" structure, which may better achieve the function of heat preservation and insulation.

[0054] It should be understood that the number of first thermal insulation structures 113 in the frame portion 112 is not limited to two, and can also be one or three or more. These are all possible implementation methods. In specific applications, technical personnel in this field can determine them based on actual needs. The structure of the frame portion 112 is related to the number of first thermal insulation structures 113. When the first thermal insulation structures 113 use other numbers, the structure of the frame portion 112 can also be adjusted accordingly.

[0055] Regarding the implementation method of the aforementioned first thermal insulation structure 113 including the first thermal insulation strip 113a and the first thermal insulation material 113b, the first thermal insulation strip 113a can be connected to the first substrate portion 112a and the first sealing plate portion 112b, and the specific connection method can be snap connection, riveting, bonding, screw connection, etc., as long as the reliability requirements of the connection can be guaranteed.

[0056] Regarding the implementation of the aforementioned first sealing component 120 being disposed on the door leaf 100, the first sealing component 120 may be disposed between the first base material portion 112a and the two first sealing plate portions 112b, and the specific assembly method may be snap connection, bonding, etc., as long as the reliability requirement of the connection can be guaranteed. In addition, the first sealing component 120 may be located outside the first heat insulation structure 113 so as to form a sealing fit with the door frame 200.

[0057] The fan body 110 may further include a first interior panel 114 and a first exterior panel 115. Figure 3 and Figure 4 The first interior trim panel 114 and the first exterior trim panel 115 can be located at the inner and outer sides of the door panel main body 111 and the frame portion 112 respectively, so as to cover the inner and outer sides of the door panel main body 111 and the frame portion 112, thereby avoiding the joint between the door panel main body 111 and the frame portion 112 from being exposed, and playing a certain decorative role.

[0058] The door frame 200 may include a frame body 210 . In the implementation mode where the first sealing member 120 is disposed on the door frame 200 , the first sealing member 120 may be disposed on the inner side of the frame body 210 so as to form a seal with the door leaf 100 .

[0059] In fact, the first sealing component 120 only needs to be set in one of the door frame 200 and the door leaf 100. Therefore, for the implementation mode in which the first sealing component 120 is set in the door leaf 100, the door frame 200 may not be provided with the first sealing component 120, so that the structural form of the eccentric door assembly provided by the embodiment of the utility model can also be relatively simple and the cost can be low; at this time, the door frame 200 may not be provided with any form of sealing component, that is, the door frame 200 may only include the frame body 210, of course, the frame body 210 may also be provided with a non-inflatable and deflated second sealing component 220, the second sealing component 220 may be, for example, a conventional sealing strip, etc., which does not need to be used with the inflation and deflation component 300, and can also better control the cost. When the first sealing component 120 is in a bulging state due to inflation, the first sealing component 120 can be contact-sealed with the second sealing component 220, which can better ensure the sealing performance between the door leaf 100 and the door frame 200.

[0060] Along the normal direction of the door frame 200, that is Figure 3 and Figure 4 In the up and down directions, the frame body 210 may also be provided with at least one second heat insulation structure 213, and the second heat insulation structure 213 may be used to improve the thermal insulation performance of the door frame 200.

[0061] The second heat insulation structure 213 may be in the same form as the first heat insulation structure 113, and a repeated description thereof will not be given here. Figure 3 and Figure 4 As shown, the second heat insulation structure 213 may include two second heat insulation strips 213a and a second heat insulation material 213b; the two second heat insulation strips 213a may be arranged at intervals, and the direction in which the two second heat insulation strips 213a are arranged at intervals may be perpendicular to the normal direction of the door leaf 100, so as to Figure 3 and Figure 4 The orientation and position relationship in is used as a reference, that is, the two second thermal insulation strips 213a can be arranged at intervals along the left-right direction; the second thermal insulation material 213b can be filled between the two second thermal insulation strips 213a, and the two second thermal insulation strips 213a can limit the second thermal insulation material 213b well, which can reduce the possibility of the second thermal insulation material 213b moving.

[0062] The structural form of the frame body 210 is consistent with the aforementioned frame portion 112 , and the structural form of the frame body 210 is also related to the number of the second thermal insulation structures 213 .

[0063] For example, the second thermal insulation structure 213 has two layers. Figure 3 and Figure 4 As shown, the frame body 210 may include a second substrate portion 211 and two second sealing plate portions 212, and the two second sealing plate portions 212 may be arranged at intervals along the normal direction of the door frame 200. Both the second substrate portion 211 and the second sealing plate portion 212 may be made of metal to ensure the structural strength of the frame body 210. The metal material may be, for example, a lightweight metal such as aluminum alloy, which may also effectively reduce the weight of the door frame 200. The second substrate portion 211 may be arranged between the two second sealing plate portions 212, and a second heat insulation structure 213 may be arranged between the second substrate portion 211 and the two second sealing plate portions 212; in this way, two second heat insulation structures 213 may be arranged in the door frame 200, and the door frame 200 may have a "double broken bridge" structure, which can better achieve the function of heat preservation and heat insulation.
