[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] A knock-automatic-opening refrigerator provided by the present invention senses vibration signals on the door body through a knock module provided on the door body, judges whether it is a preset knock vibration, and if it is a preset knock vibration, issues an instruction to make the automatic door-opening device perform automatic door opening, realizing automatic door opening and facilitating users to open the door.

[0033] In a preferred embodiment, the automatic door opening device can be applied to multiple refrigerators sharing the middle part, facilitating the application of the automatic double-door assembly structure in the middle part of refrigerators with different widths. Only new left and right hinge covers need to be opened and matched with the middle part. Further, the automatic door opening device is provided with a housing to protect the base, preventing dust and water from entering. By setting the housing contour larger than the base contour, it is convenient for the components on the base to dissipate heat. By setting fourth grooves on both sides of the housing away from the center of the refrigerator door body, part of the hinge cover is embedded in the fourth grooves to form a consistent overall structure, improving the user experience. Further, by arranging the base along the edge of the refrigerator cabinet, the stroke of the door opening actuator is reduced, and at the same time, the sound effect of the speaker is improved. Further, by arranging the support structure obliquely with the base, the sound collection has a wider range or the sound emitted by the speaker can be transmitted to a wider range when the speaker emits sound. Further, by arranging two support structures to support the speaker, the sound emitted by the speaker can fully cover the noise generated when the automatic door opening device performs the automatic door opening operation; in addition, the sound can be transmitted farther and wider in all directions.

[0034] In a preferred embodiment, the wet area box is provided with a third cavity covering the cover plate, and the third cavity extends into the storage area. The third cavity allows the gas in the internal storage area of the wet area box to enter the third cavity through the first ventilation holes, and then is dispersed to the sensor of the sensor device near the cover plate through the second ventilation holes provided on the cover plate, so that the sensor in the sensor device can detect to obtain the environmental parameters in the wet area box, such as temperature information and humidity information. By setting the third cavity, part of the gas in the storage area is gathered in the third cavity, which improves the degree of gas aggregation to a certain extent, and then improves the speed and amount of the gas overflowing from the second ventilation holes on the cover plate, so as to improve the detection speed and accuracy of the sensor of the sensor device. In addition, the setting of the cover plate reduces the amount and speed of the gas outside the wet area box entering the internal storage area of the wet area box, so as not to affect the storage environmental parameters of the wet area box. It replaces the scheme of directly setting the sensor of the sensor device on the first box body of the wet area box to avoid the influence of the sensor wire harness arrangement on the movement of the wet area box. Further, the gas in the third cavity covers the sensor of the sensor device after overflowing from the second ventilation holes on the cover plate, so that the detection object of the sensor is only the gas from the internal storage area of the wet area box, further improving the accuracy of the sensor detection structure. Further, the cover plate can be quickly loaded and unloaded through the third buckle structure. Further, the side of the cover plate facing away from the storage area is flush with the surface of the first box body, making the outer surface of the wet area box flat and beautiful without being too obtrusive. In a preferred embodiment, the wet area box is provided with a moisture preservation film body for moisture preservation. The moisture preservation film body includes a plurality of moisture preservation film cover plates stacked in sequence. The plurality of moisture preservation film cover plates are detachably connected. According to the humidity requirements of the stored items, the number of moisture preservation film cover plates can be changed, and then the thickness of the moisture preservation film body can be changed to adjust the moisture preservation property of the moisture preservation film body. It has a wide application range and is easy to adjust the moisture preservation property.

[0035] In a preferred embodiment, the present invention provides an installation structure body for fixing a sensor. The installation structure body includes an outer cover body and a fixing base body. The outer cover body is provided with a display portion, thus having a display function. Further, the display portion is recessed to form a recessed portion. The cross-section of the recessed portion is arc-shaped, forming a concave lens structure, which has the effect of optically reducing the display. When a user views from one side of the recessed portion, the size of the fixing base body on the other side of the recessed portion is smaller than its actual size, presenting a reduced image of the fixing base body. Thus, while enabling the user to observe the situation of the fixing base body, the fixing base body is presented in a reduced size. When the fixing base body covered with the outer cover body on the outside is installed on a household appliance, especially when there are several installation structure bodies provided on the inner liner of a refrigerator cabinet, the fixing base body will not be prominently displayed, thus not affecting the overall aesthetics of the household appliance. The fixing base body quickly installs and disassembles the sensor through a first snap structure, with a simple structure, quick snapping, and firm fixation. The installation structure body enables the sensor to contact the outside through a through groove for detection, ensuring the sensitivity of the sensor detection.

[0036] In a preferred embodiment, the display screen door is provided with a storage box, which is rotatably connected by a second box body and a box cover to form a closed storage box, so as to provide a closed storage space. The items in the storage box can be relatively isolated from the outside gas to prevent odor mixing. A locking structure is also provided to lock the storage box when the user does not need to use the storage box, improving the safety of using the storage box and preventing the stored items from falling. Further, a switch detection component is also provided to detect the open or closed state of the storage box and send the open or closed state of the storage box to the control board for counting, and finally feedback to the user to facilitate the user's management of the usage situation of the storage box. Further, the magnetic sensor of the switch detection component is detachably installed on the box cover through a first fixing seat, and the magnetic block is detachably installed on the second box body, which is easy to install and disassemble, facilitating the maintenance and replacement of the magnetic sensor or the magnetic block.

[0081] In order to more fully understand the invention described herein, the following embodiments are set forth. It should be understood that these embodiments are for illustrative purposes only and should not be construed as limiting the invention in any way.

[0082] Embodiment 1

[0083] The present invention provides a knocking automatic door opening refrigerator, as Figure 1 , Figure 12 shown, which includes a refrigerator body 10. The refrigerator body 10 includes a refrigerator box body 101 and a door body pivotally connected to the refrigerator box body 101. An automatic door opening device 700 is provided at the top or bottom of the refrigerator box body 101; at least one door body is provided with a knocking module 113; wherein,

[0084] The knocking module 113 senses the vibration signal on the corresponding door body and sends it to the control board electrically connected to the knocking module 113 to control the automatic door opening device 700 to be powered on to perform automatic door opening. The knocking module 113 includes a knocking sensor that can receive the vibration generated by the user knocking on the door body. The control board electrically connected to the knocking module 113 can be arranged inside the knocking module 113 or separately arranged on the door body to receive the vibration information transmitted by the knocking sensor and determine whether it is a preset knocking vibration. If it is a preset knocking vibration, the knocking signal is sent to the first control board 124 electrically connected to the automatic door opening device 700, and the first control board 124 issues an instruction to make the automatic door opening device 700 perform automatic door opening; if it is not a preset knocking vibration, the automatic door opening device 700 does not respond. In one embodiment, as Figure 12 shown, at least one end of the door body is provided with a second groove 1113 for accommodating the knocking module 113 to facilitate the loading and unloading of the knocking module 113.

[0085] In one embodiment, as Figures 2 to 6As shown, the refrigerator has double doors. The automatic door opening device 700 includes two door opening execution devices configured to perform automatic door opening. It also includes a base 72 for accommodating the door opening execution device, which is fixedly installed at one end of the refrigerator body 101. On both sides of the base 72 along the layout direction of the two door opening execution devices, there are also respectively a connection component. The base 72 is fixedly connected to the hinge covers 800 on both sides of the refrigerator body 101 through the connection components on both sides. When automatically opening the door, the two door opening execution devices perform automatic door opening to push out the door bodies on both sides of the household appliance and separate them from the magnetic seal. When the automatic door opening device 700 is installed on the top or bottom of the box body, the automatic door opening device 700 can be fixed on the surface of the box body or embedded in the refrigerator box body, but it should be noted that after being embedded in the refrigerator box body, it does not affect the automatic door opening device 700 from performing automatic door opening. The door opening execution device can be any kind of door opening execution device, such as a mechanical door opening device that uses a motor to drive a gear rack to push the door body of the refrigerator body 10; or an electromagnetic door opening device that uses the principle of electromagnetic induction to push an iron core in the direction of the refrigerator door body. The base 72 is a housing extending in one direction. The bottom of the base 72 is fixedly installed at one end of the refrigerator box body to achieve the preliminary fixation of the automatic door opening device 700. The base 72 is configured to accommodate the door opening execution device so that the automatic door opening device 700 forms an independent automatic door opening device 700.

[0086] In some embodiments, such as Figure 5As shown, the automatic door opening device 700 further includes at least one first control board 724. When only one first control board 724 is included, two door opening actuating devices are respectively configured by this first control board 724 to perform automatic door opening. In this case, the volume of the overall automatic door opening device 700 can be reduced. In some other embodiments, for the convenience of independent control and also for easy maintenance, the automatic door opening device 700 includes two first control boards 724, and the two first control boards 724 are respectively used to independently control the two door opening actuating devices. Each of the two door bodies is provided with a knocking module 113, and each knocking module 113 is electrically connected to a control board. The knocking module 113 senses the vibration signal on the corresponding door body being knocked and sends it to the control board electrically connected to the knocking module 113 to control the opening of the corresponding door body, so as to independently trigger the corresponding door opening actuating device, that is, when the user knocks on a single door body provided with the knocking module 113, the automatic door opening device 700 opens the corresponding door body. It should be understood that different door bodies have different abilities to sense knocking vibrations. By selecting a suitable vibration sensor, corresponding perception of different door bodies can be achieved. For example, when knocking on the left door body, the vibration caused by the knocking is not sufficient to be captured by the vibration sensor in the right door body, so the right automatic door opening cannot be triggered; it should also be understood that in another embodiment, a timing unit can also be configured to respectively record the time when the vibration signal is captured, and by comparing the time sequence, the vibration source can be determined. For example, it is determined that the door body that first captures the vibration signal is the door body that needs to perform automatic door opening currently; it should be further understood that in yet another embodiment, other signals can also be configured as the signal source for confirming the execution of automatic door opening. For example, voice signals, second knocking signals, touch signals, etc. are used as the signal source for confirming the execution of automatic door opening.

[0087] The automatic door opening device 700 and the hinge cover 800 can be set separately. However, when set separately, there are multiple components carried on the refrigerator cabinet, and the layout is messy, resulting in a poor user experience. To improve the user experience, the hinge cover 800 and the automatic door opening device 700 can be assembled into a structure. However, different models of refrigerators have different cabinet widths. To improve the universality of the automatic door opening device 700 in this embodiment, for the same automatic door opening device 700, only the left and right hinge covers 800 need to be newly opened to cooperate with the automatic door opening device 700, so as to facilitate direct installation and use on refrigerators with different width series without modifying the original circuit of the refrigerator.

[0088] At this time, as Figures 2 to 6As shown, the hinge cover 800 includes at least a plurality of third fixing holes 811, and fixing members such as screws are inserted into the third fixing holes 811 to fix the hinge cover 800 to one side of the refrigerator body. When the refrigerator is a double-door refrigerator, the two hinge covers 800 are respectively fixed to the left and right sides of one end of the refrigerator body. After the two hinge covers 800 are fixed, the automatic door opening device 700 is placed between the two hinge covers 800, and the base 72 is fixedly connected to the hinge covers 800 on both sides of the refrigerator body through the connecting components on both sides, that is, the hinge cover 800 is fixedly connected to the base 72 through the two connecting components on both sides of the base 72 along the two door opening actuator arrangement directions, so that the hinge covers on both sides of the refrigerator are respectively fixedly connected to the two opposite sides of the base 72 through the connecting components, and the connecting components are fixedly connected to the two opposite sides of the base 72 through the clamping structure, the screwing structure, and other fixed link structures commonly used in the art. At this time, for refrigerators of different models, only the hinge cover 800 with low processing cost needs to be newly opened.

[0089] When the door is opened automatically, under the action of the first control board 724, the two door opening actuators are controlled to perform automatic door opening, so as to push out the door bodies on both sides of the refrigerator and break away from the magnetic seal.

[0090] In some embodiments, in order to prevent the base 72 from being dusty, watery, or making excessive noises due to long-term use, the automatic door opening device 700 further includes a cover 71 that is engaged with the base 72, and an installation space for accommodating the door opening actuator is formed between the base 72 and the cover 71. The base 72 and the cover 71 are integrally formed or assembled. When the base 72 and the cover 71 are integrally formed, the automatic door opening device 700 including the door opening actuator cannot be disassembled, and the movement of the door opening actuator will not cause the base 72 and the cover 71 to deviate or move. Preferably, the base 72 and the cover 71 are assembled, and at this time, if the door opening actuator is damaged, it is easy to repair.

[0091] The contour of the housing 71 is larger than that of the base 72, so that a gap is formed between the housing 71 and the base 72; or the contour of the housing 71 is consistent with that of the base 72. Specifically, the contour size of the housing 71 matches the contour size of the base 72 or the contour size of the housing 71 is larger than the contour size of the base 72, so that a closed space or a semi-open space is formed between the housing 71 and the base 72. In some embodiments, the contour size of the housing 71 is set according to the contour size of the base 72, so that a closed structure is formed after the housing 71 and the base 72 are fastened together (without considering the fifth through hole 715 for the movement of the push rod 723 of the door opening actuator); in this case, the housing 71 and the base 72 form a good airtight space with good sound insulation effect. In other embodiments, there is at least one gap between the housing 71 and the base 72, and this gap is used for dissipating heat of the automatic door opening device. Specifically, the contour size of the housing 71 is not set according to the contour size of the base 72 and the contour of the housing 71 is larger than that of the base 72, and the housing 71 covers the area where the base 72 is located to form several gaps between the housing 71 and the base 72, which is convenient for dissipating heat of the automatic door opening device.

[0092] On one side of the housing 71 close to the door body of the refrigerator, there is also a connecting seat 713. The connecting seat 713 is snapped into the fifth groove 726 on the base 72. The connecting seat 713 can be arranged at the edge of the housing 71 on the side close to the door body of the refrigerator. Preferably, it is arranged at the center of this edge to cooperate with the second locking groove 7111 and the second locking tongue 7211 to fasten the housing 71 on the base 72.

[0093] On the edge of the side of the housing 71 far from the door body of the refrigerator, there are also several sixth recesses distributed. The sixth recesses are recessed from the housing 71 into the refrigerator cabinet. These several sixth recesses correspond to several second fixing seats 727 on the base 72. The sixth recesses also include first fixing holes 714. Fixing members such as screws are inserted into the first fixing holes 714 to fix the housing 71 on the base 72.

[0094] Such as Figures 2 to 6As shown, the connection component is a third connection part 721 extending from the base 72 along the two sides of the layout direction of the two door opening actuators, and the third connection part 721 at least includes a first lock groove 7212, and the first lock groove 7212 matches the first lock tongue 8101 of the fourth connection part 810 on the hinge cover 800, so that the third connection part 721 is fixed to one side of the fourth connection part 810 through the first lock groove 7212. In other embodiments, the third connection part 721 at least includes a first lock tongue 8101, and the first lock tongue 8101 matches the first lock groove 7212 of the fourth connection part 810 on the hinge cover 800, so that the third connection part 721 is fixed to one side of the fourth connection part 810 through the first lock tongue 8101. That is, in this embodiment, the third connection part 721 and the fourth connection part 810 are fixedly connected through the cooperation of the lock groove and the lock tongue, and the specific positions of the lock tongue and the lock groove are not limited, as long as the two match to achieve fixed connection. In some embodiments, the first lock groove 7212 is a hollow groove, and the first lock tongue 8101 is a protrusion. The hollow groove and the protrusion can be of any shape. It is only necessary to ensure that the protrusion is inserted into the hollow groove and the protrusion will not easily detach from the hollow groove, so as to fix the third connection part 721 of the base 72 below the fourth connection part 810 of the hinge cover 800.

[0095] In some embodiments, the fourth connecting portion 810 further includes a second fixing hole 8102, and a fixing member such as a screw is inserted into the second fixing hole 8102 to fix the hinge cover 800 to the refrigerator body.

[0096] In some embodiments, Figures 2 - 5 As shown, the third connection part 721 further includes a second locking tongue 7211, and the second locking tongue 7211 matches the second locking groove 7111 of the fifth connection part 711 on the cover shell 71, so as to fix the cover shell 71 above the base 72. In other embodiments, the third connection part 721 further includes a second locking groove 7111, and the second locking groove 7111 matches the second locking tongue 7211 of the fifth connection part 711 on the cover shell 71, so as to fix the cover shell 71 above the base 72. That is, in this embodiment, the third connection part 721 and the fifth connection part 711 are fixedly connected through the cooperation of the locking groove and the locking tongue, and the specific positions of the locking tongue and the locking groove are not limited, as long as the two match to achieve fixed connection. In some embodiments, the second locking tongue 7211 is a tongue-shaped member extending from the third connecting portion 721 close to the door body of the refrigerator, and the second locking groove 7111 is a groove on the side of the cover 71, which extends from the side of the cover 71 toward the center of the base 72, so that the second locking tongue 7211 is inserted into the second locking groove 7111 to fix the cover 71 on the base 72. It should be understood that the second locking tongue 7211 and the second locking groove 7111 can be a pair of other matching locks.

[0097] like Figure 2As shown, the side of the housing 71 close to the refrigerator cabinet further includes a third locking tongue 712. The third locking tongue 712 bends and extends from the housing 71 towards the refrigerator cabinet to form a bent structure. The bent structure is used to match with the third locking groove 812 on the hinge cover 800 to fixedly connect the housing 71 to the hinge cover 800. The bent structure extends from the housing 71 into the refrigerator cabinet to form a first extension arm. The end of the first extension arm extends along the direction of the base to form a second extension arm. The first extension arm and the second extension arm are generally in an L shape. The end of the second extension arm further includes a third extension arm extending towards the refrigerator cabinet. The third extension arm can be received in the third locking groove 812, and one side of the third extension arm can abut against the inner wall of the third locking groove 812. The third locking groove 812 can be a hollow groove of any shape, as long as it can receive and limit the third extension arm.

[0098] In some embodiments, the two sides of the housing 71 away from the center of the refrigerator door body respectively include a fourth groove 716. Parts of the two hinge covers 800 are respectively embedded in the fourth groove 716 so that the two hinge covers 800 and the automatic door opening device 700 form a consistent overall structure. As Figures 2 - 3 As shown, the two sides of the housing 71 respectively include a fourth groove 716. The fourth groove 716 depresses towards the center of the housing 71. The size of the fourth groove 716 is used to accommodate the fourth connecting portion 810 of the hinge cover 800 so that the two hinge covers 800 and the automatic door opening device 700 form a consistent overall structure.

[0099] In some embodiments, the side of the housing 71 close to the refrigerator door body includes a plurality of sound holes 717. The sound holes 717 are used to transmit sound to the user. When the base 72 includes a speaker 725, the sound holes 717 are arranged close to the position where the speaker 725 is located to maximize the sound transmission efficiency. The side of the housing 71 close to the refrigerator door body further includes a fifth through hole 715. When the refrigerator is a double-door refrigerator, the housing 71 includes two fifth through holes 715. The fifth through hole 715 can be of any shape, preferably circular. The push rods 723 of the two door opening actuating devices in the base 72 move through the fifth through holes 715 to open the refrigerator door body.

[0100] When arranging the position of the base 72, the base 72 only needs to be arranged at one end of the refrigerator body (the top of the refrigerator body or the bottom of the refrigerator body). In some embodiments, when the push rod 723 of the automatic double-door device body is initially a distance away from the refrigerator door body, in order to shorten the movement space of the push rod 723 on the automatic double-door device body and improve the door opening efficiency, the base 72 is arranged close to the edge of the refrigerator body close to the door body of the refrigerator, so that the push rod 723 only needs to move a small stroke to contact the door body of the refrigerator. In addition, if the push rod 723 of the automatic double-door device body initially contacts the refrigerator door body but the resistance force is not enough to make the refrigerator door body break away from the magnetic seal, the base 72 is arranged close to the edge of the refrigerator body close to the door body of the refrigerator to save the processing cost of the push rod 723. In some embodiments, the end of the push rod 723 also includes a rubber cap 722 to protect the refrigerator door body when the push rod 723 hits the refrigerator door body.

[0101] In some embodiments, the base 72 includes a first placement area 733 and a second placement area 734; the first placement area 733 is used to place a first control board 724, and the second placement area 734 is used to place a first control board 724; the two first control boards 724 are located on the same side or different sides of the two door opening actuators. Figure 4 As shown, the first placement area 733 and the second placement area 734 are located on the same side of the two-door actuator. In some embodiments, the first placement area 733 and the second placement area 734 are located on different sides of the two-door actuator. For example, the first placement area 733 and the second placement area 734 are located on both sides of the base 72, and the two-door actuator is located between the first placement area 733 and the second placement area 734. In this case, when the first placement area 733 and the second placement area 734 are provided with speakers 725, it is convenient to collect a wider range of sounds or emit sounds to a wider range. In other embodiments, the first placement area 733 and the second placement area 734 can be one area, in which case the size of the base 72 can be reduced.

[0102] In some embodiments, the base 72 further includes at least one supporting structure (not shown), which is used to fix the speaker 725 on the base 72. The supporting structure is arranged at any position on the refrigerator body. In order to ensure the sound transmission effect, the supporting structure is preferably arranged on the side of the refrigerator body close to the door of the refrigerator. Preferably, both sides of the base 72 respectively include a supporting structure, which is used to fix two speakers 725 (one speaker) on both sides of the base 72. In other embodiments, the two supporting structures are respectively arranged to be tilted with the base 72 to fix the speaker and / or tilted to the base, and the speaker 725 is arranged to transmit sound from a farther range by tilting.

[0103] like Figure 1 , Figure 21 , Figure 22As shown in the figure, a door body is a display screen door 102 provided with a display screen 220. Further, for the large-sized display screen 220 that gives users a high-end interactive visual experience, the display screen 220 occupies most of the space of the display screen door 102, resulting in insufficient remaining space inside the display screen door 102, which is not convenient for installing the knocking module 113 inside the display screen door 102. For example, for the display screen door 102 with a large-sized display screen 220 of 15.6 inches or 21 inches, the display screen 220 and the bracket body 210 for installing the display screen 220 greatly occupy the longitudinal space of the display screen door 102. If a structure for accommodating the knocking module 113 is provided inside the display screen door 102, it will cause an increase in the longitudinal dimension or thickness of the display screen door 102, resulting in cost waste and affecting the overall aesthetics of the display screen door 102. Therefore, the knocking module 113 is arranged inside the upper end cover body 110 of the display screen door 102. The arrangement of the knocking module 113 and the large-sized display screen 220 does not interfere with each other, and the arrangement of the knocking module 113 does not affect the overall size of the display screen door 102. The upper end cover body 110 includes a first cover body 111 and a second cover body 112 fixed to the top of the first cover body 111. As Figure 7 As shown in the figure, the first cover body 111 is provided with a second groove 1113 for accommodating a wiring terminal and the knocking module 113. A fifth through groove 11131 for a wire harness to pass through is provided in the second groove 1113; a first through hole 11151 for pivotally connecting to a household appliance box body is further provided on the first cover body 111; the wire harness of the display screen assembly 200 of the display screen door 102 passes through the fifth through groove 11131 and is connected to the wiring terminal, and the wire harness inside the refrigerator box body 101 passes through the first through hole 11151 and the fifth through groove 11131 in sequence and is connected to the wiring terminal.

[0104] In an embodiment, as Figure 1 As shown in the figure, a wet area box 400 and a dry area box are provided inside the refrigerator box body 101; sensors corresponding to the wet area box 400 and the dry area box are provided on the inner wall of the refrigerator box body 101; wherein, the environmental parameters of the correspondingly arranged wet area box 400 and / or dry area box are detected by the sensors, and the detected environmental parameter information is sent to a control board electrically connected to the sensors and displayed on the display screen 220.

[0105] In an embodiment, as Figures 9 to 12 As shown in the figure, the wet area box 400 is detachably connected with a moisture preservation film body 410, and the moisture preservation film body 410 faces the storage cavity of the wet area box 400; the moisture preservation film body 410 includes a plurality of moisture preservation film covers, and two adjacent moisture preservation film covers are stacked in sequence to form a moisture preservation structure of the wet area box 400.

[0106] In one embodiment, the moisture retaining film cover plate is a sponge layer or a silicon filter membrane, which has a good water absorption and storage function. When the air humidity in the surrounding environment of the moisture retaining film cover plate is relatively high, the moisture retaining film cover plate absorbs moisture from the surrounding environment; when the surrounding environment is dry and the humidity is less than the moisture contained in the moisture retaining film cover plate itself, the moisture retaining film cover plate releases moisture to the surrounding environment, so as to adjust the humidity in the storage cavity of the wet area box 400 to a certain extent.

[0107] In one embodiment, as Figure 9 shown, two adjacent moisture retaining film cover plates are engaged or buckled with each other, which is convenient for loading and unloading, so as to form a moisture retaining film body with different degrees of moisture retaining performance by stacking in sequence. Further, the moisture retaining film cover plate has a flat plate structure, and two adjacent moisture retaining film cover plates are closely adjacent to each other.

[0108] In one embodiment, as Figure 9 shown, the moisture retaining film body 410 further includes a plurality of fiber holes 411 to provide a certain degree of ventilation for the wet area box 400, so as to avoid excessive accumulation of moisture volatilized by the fruits and vegetables stored in the wet area box 400 due to complete sealing, exceeding the water absorption performance of the moisture retaining film body 410, resulting in excessive moisture in the first box body 420 of the wet area box 400, and forming condensate water on the inner wall of the first box body 420 or the surface of the fruits and vegetables, which is not conducive to the storage of fruits and vegetables. In addition, a completely sealed storage cavity will also cause excessive accumulation of ethylene released when storing fruits and vegetables, resulting in the rotting of fruits and vegetables.

[0109] Further, the sizes of the plurality of fiber holes 411 may be different, but the ventilation performance of each part of the overall moisture retaining film body 410 is uniform to provide uniform ventilation.

[0110] In one embodiment, as Figure 9 、 Figure 10 shown, the number of moisture retaining film cover plates is two, and the moisture retaining film body 410 includes a first moisture retaining film cover plate 412 and a second moisture retaining film cover plate 413; the second moisture retaining film cover plate 413 is embedded in the first moisture retaining film cover plate 412. A plurality of first fiber holes of the first moisture retaining film cover plate 412 correspond to and communicate with a plurality of second fiber holes of the second moisture retaining film cover plate 413 one by one to form the fiber holes 411.

[0111] In one embodiment, the moisture retaining film cover plate is integrally formed with a clamping structure, so that two adjacent moisture retaining film cover plates can be detachably connected.

[0112] Further, as Figure 9 、 Figure 10 、 Figure 11As shown in the figure, the first moisture-proof film cover plate 412 extends towards the first box body 420 of the wet area box 400 with a side wall structure; the side wall of the first moisture-proof film cover plate 412 extends into the installation groove 431 of the second shelf 430 of the wet area box 400 and is snap-connected to the inner wall of the installation groove 431. Specifically, side walls are provided on the periphery of the first moisture-proof film cover plate 412, and the outer walls of the side walls on the periphery of the first moisture-proof film cover plate 412 are closely attached to the inner wall of the installation groove 431 of the second shelf 430.

[0113] Further, the side wall of the first moisture-proof film cover plate 412 is provided with a first clamping groove 4121 to be snap-connected to the first clamping buckle 4311 provided in the installation groove 431. In an embodiment, a first clamping buckle 4311 is respectively provided on the inner walls of two opposite side walls of the installation groove 431, and the two first clamping buckles 4311 form opposite clamping forces. The first clamping buckle 4311 is buckled into the first clamping groove 4121 at the corresponding position to clamp both sides of the first moisture-proof film cover plate 412, thereby realizing the fixation of the first moisture-proof film cover plate 412. Further, the number of the first clamping grooves 4121 provided on the same side wall of the first moisture-proof film cover plate 412 is several, which improves the clamping strength.

[0114] In an embodiment, as Figure 9 , Figure 10 , Figure 12 shown, the second moisture-proof film cover plate 413 extends towards the first box body 420 with a side wall structure; the side wall of the second moisture-proof film cover plate 413 is snap-connected to the side wall of the first moisture-proof film cover plate 412. The outer wall of the side wall of the second moisture-proof film cover plate 413 is closely attached to the inner wall of the side wall of the first moisture-proof film cover plate 412, so that the second moisture-proof film cover plate 413 is embedded in the first moisture-proof film cover plate 412 and is tightly abutted by the inner wall of the side wall of the first moisture-proof film cover plate 412 to stabilize the fixation of the second moisture-proof film cover plate 413.

[0115] Further, the side wall of the first moisture-proof film cover plate 412 is provided with a second card slot 4122, and the side wall of the second moisture-proof film cover plate 413 is provided with a fourth card protrusion 4131 that is engaged with the second card slot 4122 or a second buckle 4132 that is buckled. In one embodiment, two opposite side walls of the second moisture-proof film cover plate 413 are respectively provided with a fourth card protrusion 4131, and the two fourth card protrusions 4131 form opposite clamping forces. The fourth card protrusion 4131 is inserted into the second card slot 4122 at a corresponding position to realize the clamping connection between the first moisture-proof film cover plate 412 and the second moisture-proof film cover plate 413. Further, the number of the second card slots 4122 provided on the same side wall of the first moisture-proof film cover plate 412 is several, and the number of the fourth card protrusions 4131 provided on the second moisture-proof film cover plate 413 corresponding to the positions of the second card slots 4122 is several, so as to improve the firmness of the clamping connection between the first moisture-proof film cover plate 412 and the second moisture-proof film cover plate 413. In one embodiment, two opposite side walls of the second moisture-proof film cover plate 413 are respectively provided with a second buckle 4132, which is buckled into the second card slot 4122 to realize the buckling between the first moisture-proof film cover plate 412 and the second moisture-proof film cover plate 413. In one embodiment, among the two opposite side walls of the second moisture-proof film cover plate 413, one side wall is provided with two fourth card protrusions 4131, and the other side wall is provided with two second buckles 4132. One side wall of the second moisture-proof film cover plate 413 is clamped with the first moisture-proof film cover plate 412, and the other side wall is buckled with the first moisture-proof film cover plate, so that the second moisture-proof film cover plate 413 is installed on one side of the first moisture-proof film cover plate 412; the buckle installation on one side makes the second moisture-proof film cover plate 413 firmly fixed, and the clamping installation on the other side fixes the second moisture-proof film cover plate 413 on this side while facilitating disassembly.

[0116] In one embodiment, as Figure 9 shown, the side wall of the first moisture-proof film cover plate 412 is provided with a thirteenth abutting portion 4123 for abutting against the inner wall of the installation groove 431. Specifically, the thirteenth abutting portion 4123 is provided on each peripheral side of the first moisture-proof film cover plate 412 to increase the abutting area between the side wall of the first moisture-proof film cover plate 412 and the inner wall of the installation groove 431, and improve the firmness of the installation groove 431 for fixing the first moisture-proof film cover plate 412.

[0117] In one embodiment, the side wall of the second moisture-proof film cover plate 413 is provided with a fourteenth abutting portion (not shown in the figure) for abutting against the inner wall of the side wall of the first moisture-proof film cover plate 412, so as to increase the contact area between the side wall of the second moisture-proof film cover plate 413 and the side wall of the first moisture-proof film cover plate 412, and make the installation of the second moisture-proof film cover plate 413 more stable after being embedded in the first moisture-proof film cover plate 412.

[0118] In one embodiment, as Figure 9As shown, the peripheral side of the first moisture preservation film cover plate 412 extends in the plane direction of the outer surface of the second shelf 430, and has a fifteenth abutting portion 4124 for abutting against the outer surface of the second shelf 430 to limit the movement of the first moisture preservation film cover plate 412 in the direction towards the first box body 420. The side wall of the first moisture preservation film cover plate 412 extends into the installation groove 431 provided in the second shelf 430, and the side wall of the first moisture preservation film cover plate 412 abuts against the inner wall of the installation groove 431. The fifteenth abutting portion 4124 of the first moisture preservation film cover plate 412 abuts against the outer surface of the second shelf 430 on the side facing away from the first box body 420. The fifteenth abutting portion 4124 restricts the movement of the first moisture preservation film cover plate 412 in the direction towards the first box body 420, and the snap connection between the first card slot 4121 and the first snap 4311 of the second shelf 430 restricts the movement of the first moisture preservation film cover plate 412 in the direction towards or away from the first box body 420.

[0119] In an embodiment, the moisture preservation film cover plate includes a film with moisture preservation property and a snap connection structure for detachably connecting adjacent moisture preservation film cover plates. Further, the moisture preservation film cover plate further includes a fixing frame for fixing the film with moisture preservation property. At the same time, the fixing frame is provided with a snap connection structure so that adjacent two moisture preservation film cover plates are stacked. Specifically, the side wall structure of the first fixing frame of the first moisture preservation film cover plate 412 extends in the direction towards the first box body 420 of the wet area box 400 to extend into the installation groove 431 of the second shelf 430 of the wet area box 400. The first fixing frame is provided with a first card slot 4121 for snap connection with the first snap 4311 provided in the installation groove 431. The first fixing frame is provided with a second card slot 4122, and the side wall of the second fixing frame of the second moisture preservation film cover plate 413 is provided with a fourth snap protrusion 4131 that engages with the second card slot 4122 or a second snap 4132 for snap connection, so that the first fixing frame and the second fixing frame are fixed. Further, the first fixing frame is provided with a thirteenth abutting portion 4123 for abutting against the inner wall of the installation groove 431 to increase the abutting area between the side wall of the first moisture preservation film cover plate 412 and the inner wall of the installation groove 431 and improve the fixing firmness of the installation groove 431 to the first moisture preservation film cover plate 412. Further, the first fixing frame is provided with a fourteenth abutting portion (not shown in the figure) for abutting against the inner wall of the side wall of the first moisture preservation film cover plate 412 to increase the contact area between the side wall of the second moisture preservation film cover plate 413 and the side wall of the first moisture preservation film cover plate 412, so that the installation is more stable after the second moisture preservation film cover plate 413 is embedded in the first moisture preservation film cover plate 412. Further, the peripheral side of the first fixing frame extends in the plane direction of the outer surface of the second shelf 430 and has a fifteenth abutting portion 4124 for abutting against the outer surface of the second shelf 430 to limit the movement of the first moisture preservation film cover plate 412 in the direction towards the first box body 420.

[0120] When installing the moisture preservation film body 410, the first moisture preservation film cover plate 412 can be installed in the installation groove 431 first, and then the second moisture preservation film cover plate 413 can be installed on the side of the first moisture preservation film cover plate 412 facing the first box body 420; alternatively, the second moisture preservation film cover plate 412 can be installed on the first moisture preservation film cover plate 412 first to form the moisture preservation film body 410, and then the moisture preservation film body 410 can be installed in the installation groove 431.

[0121] It should be understood that the moisture preservation film body 410 may further include, but is not limited to, a third moisture preservation film cover plate and a fourth moisture preservation film cover plate, and the first moisture preservation film cover plate 412, the second moisture preservation film cover plate 413, the third moisture preservation film cover plate, and the fourth moisture preservation film cover plate are sequentially stacked.

[0122] In one embodiment, as Figure 1 shown, both the wet area box 400 and the dry area box are drawer boxes, which is convenient for users to take and place items.

[0123] Furthermore, a third cavity 440 is respectively recessed in an outer wall of the wet area box 400 and the dry area box, and a cover plate covers the open end of the third cavity 440, and the cover plate faces the correspondingly arranged sensor; wherein,

[0124] The third cavity 440 is provided with a plurality of first ventilation holes 442; the cover plate is provided with a plurality of second ventilation holes;

[0125] The third cavity 440 collects the gas in the storage area where the third cavity 440 extends through the first ventilation holes 442 and overflows from the correspondingly arranged second ventilation holes, so that the sensor can obtain the current environmental parameters in the correspondingly arranged storage area by sensing the environment around the cover plate. That is, the wet area box 400 and the dry area box are respectively provided with a third cavity 440 covered with a cover plate.

[0126] Taking the wet area box 400 as an example, as Figure 7 、 Figure 8 shown. The third cavity 440 provided in the dry area box and the structure covering the third cavity 440 are the same as those of the third cavity 440 provided in the wet area box 400 of the wet area box 400, and will not be described in detail here. The gas in the storage area of the wet area box 400 enters the correspondingly arranged third cavity 440 through the first ventilation holes 442 on the wet area box 400 and then overflows from the second ventilation holes, so that the sensor correspondingly arranged on the wet area box 400 can obtain the current environmental parameters in the storage area by sensing the environment around the cover plate. The third cavity 440 extends into the storage area. When the gas in the storage area flows, some gas will inevitably touch the outer wall of the third cavity 440, and then will contact the first ventilation holes 442 and pass through the first ventilation holes 442 into the third cavity 440, making it easier for the gas in the storage area to enter the third cavity 440 through the first ventilation holes 442 provided in the third cavity 440.

[0127] Further, a plurality of third through grooves 443 for ventilation are provided on the side wall of the third cavity 440 to increase the speed and amount of gas entering the third cavity 440 from the storage area.

[0128] In one embodiment, a plurality of second ventilation holes arranged on the cover plate enable the gas discharged from the second ventilation holes to cover the sensors correspondingly arranged with the wet area box 400. The plurality of second ventilation holes are evenly distributed on the cover plate, and the gas in the third cavity 440 continuously penetrates through the second ventilation holes and always covers the outer contour of the sensors, so that the detection object of the sensors in the sensors is the gas in the storage area of the wet area box 400, and is not affected by the gas in other areas of the refrigerator cabinet 101.

[0129] In one embodiment, a plurality of third snap structures 441 for fixing the cover plate are provided on the outer wall of the wet area box 400 to quickly load and unload the cover plate. At least two third snap structures 441 form a relative or opposite snap force to snap the cover plate onto the wet area box 400, and the cover plate is provided with a slot or a snap structure that snaps with the third snap structure 441. After the cover plate covers the third cavity 440, the cover plate and the third cavity 440 form a space with a certain sealing property. Since the third cavity 440 extends into the storage area of the wet area box 400, it is easier for the gas in the storage area to enter the third cavity 440 than the gas outside the wet area box 400. Thus, after the gas in the storage area accumulates in the third cavity 440, it overflows from the second ventilation holes on the cover plate and dispersedly covers the sensors correspondingly arranged with the wet area box 400, so that the sensors can perform detection, and then the environmental parameters in the storage area of the wet area box 400 can be obtained.

[0130] In one embodiment, the third snap structure 441 includes a buckling portion 4411 and a second receiving portion 4412; the buckling portion 4411 is used to buckle with the snap structure or slot provided on the cover plate; the second receiving portion 4412 is fixed in the third cavity 440, and the buckling portion 4411 is connected to one end of the second receiving portion 4412.

[0131] In one embodiment, the third snap structure 441 is provided on the outer wall of the wet area box 400, and a plurality of third snap structures 441 are distributed around the third cavity 440. At least two third snap structures 441 form a relative snap force, and the buckling portions 4411 of the third snap structures 441 forming the relative snap force are arranged facing each other. In another embodiment, at least two third snap structures 441 form an opposite snap force, and the buckling portions 4411 of the third snap structures 441 forming the opposite snap force are arranged back to back. The cover plate is provided with a slot or a snap structure that matches the third snap structure 441. The third snap structure 441 buckles the slot or the snap structure to fix the cover plate on the wet area box 400, and the side of the cover plate facing the third cavity 440 extends into the third cavity 440.

[0132] In one embodiment, the third snap structure 441 is disposed within the third cavity 440. At least two third snap structures 441 form opposite snap forces, and the latching portions 4411 of the third snap structures 441 that form the opposite snap forces are arranged facing each other; or, at least two third snap structures 441 form reverse snap forces, and the latching portions 4411 of the third snap structures 441 that form the reverse snap forces are arranged back to back. The cover plate is fixed to the wet area box 400, and the side of the cover plate facing the third cavity 440 extends into the third cavity 440.

[0133] Further, two third snap structures 441 are respectively provided on two opposite sides of the third cavity 440, and the third snap structures 441 located on both sides of the third cavity 440 are arranged at opposite positions to increase the snap strength.

[0134] In one embodiment, both sides of the third through groove 443 are respectively connected to the outer wall of a second receiving portion 4412. The inner wall of the third cavity 440 facing away from the storage area is connected to the side wall around the third cavity 440 through the second receiving portion 4412, and the length of the third through groove 443 is increased, and the speed and the amount of gas in the storage area entering the third cavity 440 through the third through groove 443 are increased.

[0135] In one embodiment, an installation table 444 is provided on the inner wall of the third cavity 440; the outer wall of the side of the cover plate facing the third cavity 440 abuts against the installation table 444, and the side of the cover plate facing away from the third cavity 440 closes the third cavity 440. The third snap structure 441 snaps onto a matching snap structure or a card slot provided on the cover plate, so that the outer wall of the side of the cover plate facing the third cavity 440 abuts against the installation table 444. In one embodiment, after the outer wall of the side of the cover plate facing the third cavity 440 abuts against the installation table 444, the outer wall of the side of the cover plate facing away from the third cavity 440 is flush with the outer wall of the wet area box 400, making the surface of the wet area box 400 flat and beautiful.

[0136] In one embodiment, as Figure 10 shown, the wet area box 400 is provided with a fourth anti-fooling portion 450 for indicating the installation direction of the cover plate. Further, the fourth anti-fooling portion 450 is provided on the third cavity 440. In one embodiment, a plurality of first ventilation holes 442 provided in the third cavity 440 are arranged to form a specific pattern to form an indicating function to constitute the fourth anti-fooling portion. In another embodiment, the third cavity 440 is provided with a mark to constitute the fourth anti-fooling portion. Further, the fourth anti-fooling portion is a triangular icon for indicating the installation direction of the cover plate.

[0137] In one embodiment, as Figure 8As shown, the wet area box 400 is provided with a third mounting hole 460 for fixing one end of the cover plate. One end of the cover plate is convexly provided with a mounting plate, and the mounting plate is fixed to the outer wall of the wet area box 400 through the connection of a screw with the third mounting hole 460. After the cover plate is fixed by the third snap structure 441, it is further reinforced by screws. While ensuring firm fixation, when loading and unloading, only one screw needs to be screwed, which reduces the loading and unloading time to a certain extent.

[0138] In one embodiment, the wet area box 400 includes a first box body 420 provided with a storage area, and the third snap structure 441 and the first ventilation holes 442 are provided on the outer wall of the first box body 420. The wet area box 400 further includes a second shelf 430, and the second shelf 430 is arranged at the opening end of the first box body 420, sealing the storage area of the first box body 420 to a certain extent.

[0139] The wet area box 400 is of a drawer type. When taking and placing items, the wet area box 400 needs to be pulled out. The wet area box 400 moves relative to the inner wall of the refrigerator cabinet. The sensor is arranged on the inner wall of the refrigerator cabinet instead of directly on the wet area box 400, so as to avoid the necessary wire harness carried by installing the sensor on the wet area box 400 from affecting the movement of the wet area box 400 when the wet area box 400 is pulled out.

[0140] As Figure 1 As shown, there are also several storage areas in the refrigerator cabinet 101. At least two storage areas are respectively configured with a sensor to detect the environmental parameters of the corresponding storage areas and send the detected environmental parameter information to the control board electrically connected to the sensor, and push storage guidance information to the user on the display screen 220. Further, each storage area is configured with a sensor to detect the environmental parameters of the storage area in real time. The storage areas are relatively independent of each other. Each storage area is configured with a sensor to detect the environmental parameters in each storage area, so as to facilitate the classified storage of the types of items to be placed in different storage areas.

[0141] In one embodiment, the refrigerator body 101 is provided with a plurality of first shelves 1011 to divide the refrigerator body 101 transversely to form a plurality of storage areas; the sensor is arranged on the inner liner of the refrigerator body 101. Furthermore, the plurality of storage areas are arranged in the refrigeration chamber, and the sensor is a temperature sensor. Specifically, the refrigerator body 101 includes two first shelves 1011, and the two sides of the first shelves 1011 are respectively placed on the shelves provided on the outer wall of the inner liner of the refrigerator body 101, and the refrigerator body 101 is transversely divided to form three relatively independent storage areas arranged longitudinally in sequence, namely, the first storage area, the second storage area, and the third storage area arranged in sequence from top to bottom, and the three storage areas are not completely independent. For an air-cooled refrigerator, in one embodiment, the cold air outlet is arranged at the top of the refrigerator body 101, and the cold air blows from top to bottom, blowing through the first storage area, the second storage area, and the third storage area in sequence. As the cold air discharged from the cold air outlet flows, the cold air and the gas in the refrigerator body 101 are heat-conducted and heated. When the cold air is transmitted to the third storage area, the temperature of the cold air is lower than the temperature when the cold air is just transmitted to the first storage area, that is, to a certain extent, the temperatures of the first storage area, the second storage area, and the third storage area are not the same, and they are all different. The temperature from top to bottom is a temperature ladder and increases in sequence. The temperature in the corresponding storage area is detected by sensors respectively arranged in the first storage area, the second storage area, and the third storage area, and the temperature information of the corresponding storage area is obtained and transmitted to the control panel. The control panel configures storage guidance instructions to instruct the user how to classify and store in the corresponding three storage areas.

[0142] In one embodiment, the sensor includes a temperature sensor, a humidity sensor, and a temperature and humidity sensor to sense the temperature and humidity in the storage area of ​​the wet area box 400 or to obtain the temperature and humidity conditions simultaneously.

[0143] Furthermore, if Figures 32 to 34 As shown, the sensor also includes a mounting structure body 300 for mounting the sensor; the mounting structure body 300 includes an outer cover body 310 and a fixing seat body 320 for fixing the sensor; the outer cover body 310 covers the outside of the fixing seat body 320; wherein,

[0144] The outer cover body 310 is provided with a display part that is semi-transparent or completely transparent. The display part is recessed to form a second recess 311. The cross-section of the second recess 311 is arc-shaped, forming a concave lens structure to present a reduced image of the fixing seat body 320. The concave lens structure has a diverging effect on light. After parallel light rays are refracted by the concave spherical lens, the light rays diverge and become diverging light rays, and it is impossible to form a real focus. The image formed by the concave lens structure is always a virtual image that is smaller than the object and upright. The second recess 311 with an arc-shaped concave surface provided in the display part gives the user a visual effect that the size of the fixing seat body 320 covered by the outer cover body 310 becomes smaller. When the fixing seat body 320 installed on the outside of the outer cover body 310 is installed inside the household appliance, it is convenient to view the fixing seat body 320, and at the same time, there will be no visual conflict with other structures of the household appliance, that is, it will not damage the integrity of the household appliance box body, giving the user a gentle visual experience.

[0145] The installation structure body 300 is provided with a through groove to locally expose the sensor outside the side wall of the installation structure body 300 away from the sensor, so that the sensor contacts the outside through the through groove, enabling the sensor to sense the environment of the corresponding storage area through the through groove and perform detection. Further, the sensor is close to the through groove, enabling the sensor to quickly sense the environment of the corresponding storage area through the through groove.

[0146] In one embodiment, the installation structure body 300 is a plastic part, which is light and easy to process and has a certain elasticity.

[0147] In one embodiment, the outer cover body 310 is fixed to the outer surface of the fixing seat body 320 away from the sensor by secondary injection molding. The outer cover body 310 and the fixing seat body 320 are of an integral structure, eliminating the buckle connection structure or other connection structures.

[0148] In one embodiment, the outer cover body 310 is connected to the fixing seat body 320 by a buckle. The buckle connection is convenient for disassembly. According to the user's needs, the user can choose whether to install the outer cover body 310 by himself.

[0149] In order to produce a symmetrical reduced display effect and avoid the situation that different degrees of reduced display in different parts bring an unpleasant visual experience to the user. In one embodiment, as Figure 32 shown, the second recess 311 has a central symmetry structure. Specifically, the outer edge contour of the second recess 311 is oval or circular, and the contour corners are rounded. Preferably, the outer edge contour of the second recess 311 is oval, and the long axis direction of the oval exposes more of the structure of the fixing seat body to the outside.

[0150] In one embodiment, as Figure 32As shown, the through groove includes a first through groove 3111 and a second through groove 321 which are respectively arranged on the outer cover body 310 and the fixing seat body 320; the first through groove 3111 is connected to the second through groove 321. The outer contour of the first through groove 3111 covers the outer contour of the second through groove 321, that is, the first through groove 3111 and the second through groove 321 correspond in position, and have the same shape and size, so that the mounting structure body 300 can expose the sensor while having a neat appearance. The outer contour of the second through groove 321 on the side away from the first through groove 3111 is close to the sensor to improve the detection sensitivity of the sensor. Usually the sensor is cylindrical, and the first through groove 3111 and the second through groove 321 are elongated to expose the sensor fixed on the inner side of the fixing seat body 320 to the outside, so as to sense the changes in the environmental parameters of the corresponding storage area. In one embodiment, as Figure 2 As shown, the first through slot 3111 is disposed on the second recessed portion 311 , and when the second recessed portion 311 is reduced in size, the visual effect captures the user's field of vision while highlighting the sensor portion exposed by the first through slot 3111 .

[0151] In order to ensure the symmetrical display effect of the second recessed portion 311, in one embodiment, Figure 32 As shown, the symmetry axis of the first through slot 3111 coincides with the symmetry axis of the second recessed portion 311 , thereby preventing the first through slot 3111 from affecting the symmetry effect of the second recessed portion 311 and further affecting the display effect of the second recessed portion 311 .

[0152] In one embodiment, a first connecting portion 312 is provided at the connection between the outer surface of the second recessed portion 311 and the peripheral side of the first through groove 3111. The first connecting portion 312 is in the form of a slope, and the slope is inclined toward the first through groove 3111. The setting of the first connecting portion 312 provides a transition surface for the user, further expanding the exposure range of the first through groove 3111 to reveal the fixing seat body; at the same time, the outer cover body 310 has a clear outline.

[0153] In one embodiment, the outer cover body 310 is a semi-transparent component or a completely transparent component. The outer cover body 310 presents a complete structural display effect to the fixing seat body 320 of the covered object, and the overall display is more beautiful and direct.

[0154] In one embodiment, a first extension portion 313 is provided on the outer surface of the outer cover body 310, which is a sloped surface and tilted toward the fixing seat body. The first extension portion 313 tilts toward the fixing seat body 320 to form a structure that wraps the fixing seat body 320, so that the outer cover body 310 can completely cover the fixing seat body 320.

[0155] In one embodiment, a second connecting portion 314 for connecting the second recessed portion 311 and the first extending portion 313 is provided on the outer surface of the outer cover body 310, so as to avoid the direct connection between the second recessed portion 311 and the first extending portion 313, where the included angle is too sharp, which is not easy to process and is likely to scratch the contact person. In addition, the streamline of the outer surface of the outer cover body 310 is made soft, and there will be no abrupt sharp corners that affect the touch feeling; in addition, the first extending portion 313 gives the user a visual transition, and the outer cover body 310 has a distinct outline, presenting a gentle display effect.

[0156] In one embodiment, as Figure 2 The second connecting portion 314 is parallel to the horizontal plane. The second connecting portion 314 is connected to the second recessed portions 311 and the first extending portions 313 on both sides, and the included angles between the second connecting portion 314 and the second recessed portions 311 and the first extending portions 313 on both sides are both greater than 90°, so as to avoid the formation of sharp included angles, and further make the streamline of the outer surface of the outer cover body 310 soft.

[0157] In one embodiment, the cross-section of the inner surface of the second recessed portion 311 has the same streamline structure as the cross-section of the outer surface, so that the outer cover body 310 symmetrically presents a reduced image of the fixed seat body.

[0158] In one embodiment, as Figure 33 、 Figure 34 As shown, a plurality of first buckle structures 322 are provided on the inner wall of the fixed seat body 320; at least two of the first buckle structures 322 have opposite buckling directions, and form a relative buckling force on both sides of the sensor to buckle the sensor on the surface of the fixed seat body 320.

[0159] In one embodiment, a plurality of first buckle structures 322 are arranged in two columns, and the second through groove 321 is located between the plurality of first buckle structures 322 arranged in two columns. Further, the second through groove 321 is close to the sensor. After the first buckle structure 322 buckles the sensor, the sensor is in direct contact with the second through groove 321 to improve the sensing sensitivity of the sensor to the outside. Further, the buckling forces of the plurality of first buckle structures 322 located on both sides of the second through groove 321 are opposite. Among them, the second through groove 321 faces the sensor partially or entirely, so that the sensor communicates with the outside through the second through groove 321 and the first through groove 3111 for detection.

[0160] In one embodiment, the number of the first buckle structures 322 is two, which appropriately reduces the buckling difficulty and facilitates loading and unloading. Further, in order to improve the buckling fastness of the sensor, the two first buckle structures 322 are arranged in a staggered manner to buckle different lateral positions of the sensor respectively. The buckling fixation of different lateral positions of the sensor is realized, the fixation fastness of the sensor is improved, and the number of the first buckle structures 322 is two, so the buckling force is not too large, which facilitates the removal of the sensor from the buckling action of the two first buckle structures 322. Similarly, when buckling, the buckling difficulty is also relatively reduced.

[0161] In one embodiment, the outer contour of the sensor covers the outer contour of the second through groove 321 facing the sensor side, that is, the second through groove 321 directly faces the sensor completely, and the contact surface between the sensor and the outside world is the largest, which improves the detection sensitivity of the sensor.

[0162] In order to further improve the fixation fastness of the sensor, in one embodiment, as Figure 33 , Figure 34 shown, a plurality of tenth abutting parts 323 are further arranged on the inner wall of the fixing seat body 320 to respectively abut against the outer walls on both sides of the sensor, and the plurality of tenth abutting parts 323 are respectively arranged on both sides of the second through groove 321 where the first buckle structure 322 is provided. The tenth abutting parts 323 on both sides of the second through groove 321 only limit the movement of the sensor along the direction towards or away from any one of the tenth abutting parts 323, but do not increase the loading and unloading difficulty of the sensor.

[0163] In order to simplify the structure of the fixing seat body 320 and avoid volume increase, in one embodiment, as Figure 33 shown, the number of the tenth abutting parts 323 is two, which are respectively located on both sides of the second through groove 321 to respectively abut against both sides of the sensor. In order to further improve the fixation fastness of the sensor, the two tenth abutting parts 323 are arranged in a staggered manner to respectively abut against different lateral parts of the sensor.

[0164] In one embodiment, as Figure 33 , Figure 34As shown, the first buckle structure 322 and the tenth abutting portion 323, which are respectively located on both sides of the sensor, correspond to each other in position. The first buckle structure 322 and the tenth abutting portion 323 corresponding to each other in position abut on both sides of the sensor at the same lateral position, restricting the movement of the sensor in the direction towards or away from the abutting portion. The two first buckle structures 322 arranged staggeredly buckle on both sides of the sensor at different lateral positions for fixation. That is, when the two first buckle structures 322 arranged staggeredly are buckled or detached, while ensuring the buckling strength, since the number of the first buckle structures 322 is not large, it is easy to load and unload the sensor; in addition, since a tenth abutting portion 323 corresponds to a first buckle structure 322 in position, the tenth abutting portion 323 and the first buckle structure 322 cooperate to improve the restricting force on the movement of the sensor in the direction towards or away from the abutting portion.

[0165] In order to improve the abutting strength of the tenth abutting portion 323 on the sensor, in one embodiment, as Figure 5 shown, the tenth abutting portion 323 is provided with an eleventh abutting portion 324 for abutting on the outer wall of the sensor, and the outer contour of the eleventh abutting portion 324 on the side facing the sensor completely abuts on the outer wall of the sensor. In one embodiment, the sensor is cylindrical, the outer surface of the eleventh abutting portion 324 is arc-shaped, and the arc-shaped outer contour of the eleventh abutting portion 324 completely abuts on the outer wall of the sensor, closely adhering to the cylindrical sensor, so as to increase the abutting contact surface and improve the abutting strength.

[0166] In one embodiment, as Figure 34 shown, one side of the eleventh abutting portion 324 is connected to the inner wall of the second through groove 321 provided on the fixed seat body 320, so as to improve the abutting force on the sensor near the bottom of the fixed seat body 320.

[0167] In one embodiment, as Figure 33 、 Figure 34 shown, the fixed seat body 320 is provided with a third recess 325 to partially or completely accommodate the outer contour of the side of the sensor facing the inner wall of the second through groove 321 provided on the fixed seat body 320, and the outer contour on the periphery of the third recess 325 fixes the outer wall of the sensor to a certain extent. In one embodiment, the sensor is cylindrical, and the cross section of the third recess 325 is arc-shaped to partially accommodate the outer contour of the side of the sensor facing the inner wall of the second through groove 321 provided on the fixed seat body 320.

[0168] In one embodiment, the outer contour of the sensor in the third recessed portion 325 is closely attached to the contour of the third recessed portion 325. That is, the contour of the third recessed portion 325 is the same as the outer contour of the sensor portion to be accommodated, so that when the third recessed portion 325 accommodates the outer contour of the inner wall of the fixing seat body 320 provided with the second through groove 321, the outer contour of the sensor in the third recessed portion 325 is closely attached to the contour of the third recessed portion 325, thereby improving the fixing strength of the third recessed portion 325 to the bottom of the sensor.

[0169] In one embodiment, the second through slot 321 is located in the third recessed portion 325 , and the sensor is closely attached to the third recessed portion 325 , that is, can be closely attached to the second through slot 321 .

[0170] In one embodiment, a plurality of twelfth abutting portions 326 are provided on the inner side of the fixing seat body 320, which abut against two sides of the sensor respectively, and constitute a limiting structure around the sensor together with at least two first snap-fit ​​structures 322 that form a relative snap-fit ​​force; the abutting directions of the plurality of twelfth abutting portions 326 are perpendicular to the snap-fit ​​directions of the two first snap-fit ​​structures 322, so as to abut against the two sides of the sensor that are not fixed by snap-fit, thereby limiting the movement of the sensor in the direction toward or away from the twelfth abutting portions 326.

[0171] In one embodiment, in order to simplify the structure of the fixing seat body 320 and reduce the production cost, in one embodiment, as shown in FIG. Figure 33 , Figure 34 As shown, there are two twelfth abutting portions 326. Further, in order to improve the abutting firmness of the two twelfth abutting portions 326 on the corresponding two sides of the sensor, in one embodiment, the two twelfth abutting portions 326 are staggered on both sides of the second through slot 321 to abut the staggered parts on both sides of the sensor.

[0172] In one embodiment, in order to reduce the risk of the first buckle structure 322 being buckled or detached from the sensor multiple times, Figure 34 As shown, the probability of the first buckle structure 322 being damaged due to deformation caused by multiple external forces is reduced, and a first receiving portion 328 connected to the inner wall of the fixing seat body 320 is provided at the bottom of the first buckle structure 322, and the thickness of the first receiving portion 328 is less than that of the first buckle structure 322. When the sensor is buckled or detached, the first receiving portion 328 has a smaller thickness, which reduces the difficulty of deformation under the action of external forces, reduces the probability of damage, and prolongs the service life of the fixing seat body 320.

[0173] In one embodiment, in order to increase the snap-fitting strength of the first snap-fit ​​structure 322 on the sensor, the inner contour of the first snap-fit ​​structure 322 is attached to the outer wall of the sensor, increasing the contact surface between the first snap-fit ​​structure 322 and the sensor and improving the snap-fitting strength.

[0174] In one embodiment, it further includes a protective inner cover (not shown in the figure) fixed to the inner side of the fixed seat body 320, so that the sensor is hidden in the space formed by the protective inner cover and the inner wall of the fixed seat body 320.

[0175] Further, a plurality of second snap structures 327 for snap-connecting with the protective inner cover are provided on the peripheral side of the fixed seat body 320 to install the protective inner cover on the inner side of the fixed seat body 320. The snap connection is fast, convenient for loading and unloading, protects the sensor and hides the fixed seat body 320 with the sensor fixed thereon.

[0176] In one embodiment, as Figure 32 shown, the outer surface contour of the fixed seat body 320 facing the outer cover body 310 is the same as the partial inner contour of the outer cover body 310, so that the inner side of the outer cover body 310 is closely attached to the outer surface of the fixed seat body 320 facing the outer cover body 310.

[0177] In one embodiment, a storage box 600 is provided on the display screen door 102. The storage box 600 includes a second box body 610 and a box cover 620; the second box body 610 and the box cover 620 are rotatably connected; wherein, the box cover 620 is fixed to the door liner 140; the second box body 610 and the box cover 620 rotate relative to each other so that the storage box 600 forms a closed storage space in the closed state to prevent the items stored in the storage box 600 from being affected by cross-taste and affecting the use feeling.

[0178] In one embodiment, as Figure 15 shown, a first cavity 612 is provided inside the second box body 610; one side of the first cavity 612 is open, and the opening faces away from the direction of the rotation connection between the second box body 610 and the box cover 620. When the second box body 610 is opened relative to the box cover 620, the opening angle gradually decreases from the direction away from the rotation connection between the second box body 610 and the box cover 620 towards the rotation connection between the second box body 610 and the box cover 620. By setting the opening in the direction away from the rotation connection between the second box body 610 and the box cover 620, the opening is located at the part with the largest opening angle, which is convenient for taking and placing items.

[0179] In one embodiment, as Figure 15 shown, a notch 6121 is formed by the outer wall of the first cavity 612 near the opening being concave inward, so as to facilitate the user to hold one end of the stored item from the notch 6121 and take out the item.

[0180] In one embodiment, as Figure 13 、 Figure 15 shown, one side wall of the first cavity 612 near the box cover 620 is slightly concave towards the direction away from the box cover 620 to form a tightening structure to slightly press the items stored in the first cavity 612 to prevent the items from falling off from the first cavity 612.

[0181] In one embodiment, as Figure 14 shown, on the side of the box cover 620 facing the second box body 610, a second cavity 627 is concavely formed to surround the outer wall of the first cavity 612, so as to close the opening, enabling the storage box 600 to have a relatively sealed storage function and avoid the mixing of odors.

[0182] In one embodiment, as Figure 16 shown, the storage box 600 has a square structure; first side walls 624 extend from three sides of the box cover 620, and a second side wall 625 extends from the side of the box cover 620 close to the rotation connection between the second box body 610 and the box cover 620. The three first side walls 624 and the second side wall 625 form the circumferential side walls of the second cavity 627. The first side walls 624 abut against the inner wall of the second box body 610 where the first cavity 612 is provided, and the second side wall 625 partially surrounds the outer wall of the first cavity 612 close to the rotation connection between the second box body 610 and the box cover 620. There are gaps between the second side wall 625 and the outer wall of the first cavity 612 and the inner wall of the second box body 610 where the first cavity 612 is provided, so that the second box body 610 can rotate relative to the box cover 620 smoothly or the box cover 620 can rotate relative to the second box body 610 smoothly, avoiding unnecessary contact between the outer walls of the second box body 610 and the box cover 620 during rotation and causing resistance.

[0183] In one embodiment, as Figure 14 shown, a plurality of rubber parts 622 for anti-collision are provided on one side wall of the box cover 620 facing the second box body 610. Specifically, the rubber parts 622 are arranged at one end of one side wall of the box cover 620 away from the pivot connection between the box cover 620 and the second box body 610. When the second box body 610 rotates relative to the box cover 620 to open the storage box 600, the outer wall of the box cover 620 provided with the rubber parts 622 is away from the inner wall of the second box body 610. When the storage box 600 is closed, the outer wall of the box cover 620 provided with the rubber parts 622 approaches the inner wall of the second box body 610 until they touch. Due to the rubber parts 622, a buffering force is generated when the box cover 620 touches the second box body 610, realizing anti-collision. Further, the box cover 620 is provided with fourth mounting holes 626 for mounting the rubber parts 622. Specifically, the fourth mounting holes 626 are threaded holes, and the rubber parts 622 are formed by rubber wrapping the head of a screw, and the threaded part of the screw is screwed into the fourth mounting holes 626 for installation.

[0184] In one embodiment, the two sides of the box cover 620 are snap-connected to the side wall of the door liner 140 (not shown in the figure). Specifically, third card slots 14111 are provided on the side wall of the first recessed part 1411 of the door liner 140, and the two sides of the box cover 620 are snapped into the third card slots 14111 of the door liner 140 for installation. The second box body 610 rotates relative to the box cover 620 to expose the storage space in the second box body 610 to the user, facilitating the taking and placing of items.

[0185] In one embodiment, as Figure 14 shown, the storage box 600 further includes a locking structure 650 for locking the storage box 600 when it is closed. To ensure the closing firmness of the storage box 600, in case when the storage box 600 is not in use, the second box body 610 having the first cavity 612 for storing items rotates relative to the lid 620 under its own gravity or the gravity of the stored items, opening the storage box 600 and causing the stored items to fall off.

[0186] Furthermore, the locking structure 650 includes a latch post 651 and a latch claw 652 respectively disposed on the second box body 610 and the lid 620; the latch post 651 is snapped into the latch claw 652 to restrict the second box body 610 from detaching from the lid 620. When there is no external force to open the storage box 600, the latch claw 652 restricts the latch post 651, thereby realizing the locking of the storage box 600. When opening the storage box 600, with the user applying force, the latch post 651 of the second box body 610 disengages from the latch claw 652, realizing the opening of the storage box 600.

[0187] Furthermore, the locking structure 650 is located between the open end of the second box body 610 and the rotational connection between the second box body 610 and the lid 620; and the locking structure 650 is close to the rotational connection between the second box body 610 and the lid 620. While realizing the locking of the storage box 600, the storage box 600 can be opened without excessive external force.

[0188] In one embodiment, the storage box 600 further includes a switch detection component 630 for detecting the open or closed state of the storage box 600 and sending it to a control board electrically connected to the switch detection component 630 to record the number of times the storage box 600 is opened and closed, and display it on the display screen 220. Furthermore, the switch detection component 630 is electrically connected to a second control board 240 provided in the display screen door 102. The display screen door 102 is provided with a hole for the wire harness of the switch detection component 630 of the storage box 600 to pass through. After the wire harness passes through the door liner 140 and the door panel body 120 of the display screen door 102 in sequence, it is electrically connected to the second control board 240 provided on the door panel body 120 of the display screen door 102.

[0189] Further, the switch detection component 630 includes a magnetic sensor switch 631 and a magnetic block 632 respectively disposed on the lid 620 and the second box body 610; the positions of the magnetic sensor switch 631 and the magnetic block 632 correspond to each other. The switch detection component sends the detected state information of the opening or closing of the storage box 600 to the control board electrically connected to the switch detection component 630 for counting. The control board can be disposed inside the storage box 600 or inside the installation object of the storage box 600. When the second box body 610 rotates relative to the lid 620 to open or close the storage box 600, the magnetic induction between the magnetic sensor switch 631 and the magnetic block 632 is connected or disconnected to detect the opening or closing state of the storage box 600. The switch detection component 630 sends the detected opening or closing state information of the storage box 600 according to the change of magnetic induction to the control board, and the control board feeds back to the information terminal viewable by the user according to the received information technology. Further, the magnetic block 632 is a neodymium iron boron magnetic block with high magnetism, which increases the adsorption force between the second box body 610 and the lid 620.

[0190] In one embodiment, as Figure 16 shown, the second box body 610 is provided with a fourth installation structure 611 for fixing the magnetic block 632. The fourth installation structure 611 is provided with a fourth card slot 6111 for clamping the magnetic block 632. The opening direction of the fourth card slot 6111 does not face the gravity direction of the magnetic block 632 after the storage box 600 is installed, so as to prevent the magnetic block 632 from being fixed unstably. The inner wall of the fourth card slot 6111 abuts against the outer wall of the magnetic block 632 to stably fix the magnetic block 632. Further, the magnetic block 632 is disposed on an outer wall of the second box body 610 away from the lid 620, and the magnetic block 632 can be loaded and unloaded without opening the storage box 600.

[0191] In one embodiment, as Figure 17 shown, the lid 620 is provided with a fifth installation structure 621 for fixing the first fixing seat 640. The magnetic sensor switch 631 is fixed inside the first fixing seat 640 to fix the magnetic sensor switch 631 on the lid 620, and the magnetic block 632 is fixed on the second box body 610. As the storage box 600 is opened or closed, the distance between the magnetic sensor switch 631 and the magnetic block 632 increases or decreases to connect or disconnect the magnetic induction between the magnetic sensor switch 631 and the magnetic block 632, realizing the detection of the switch state. Further, the fifth installation structure 621 is disposed on an outer wall of the lid 620 away from the second box body 610, and the magnetic sensor switch 631 can be loaded and unloaded without opening the storage box 600.

[0192] Further, as Figure 18 、 Figure 19 shown, the first fixing seat 640 is provided with a fourth buckle structure 6411 for clamping the magnetic sensor switch 631 to install the magnetic sensor switch 631 on the storage box 600. It is convenient for loading and unloading the magnetic sensor switch 631 and for maintenance or replacement.

[0193] In one embodiment, the fourth snap structure 6411 includes at least two third snaps 64111 that form opposite snap forces. Specifically, the fourth snap structure 6411 includes two third snaps 64111 that are oppositely arranged to form opposite snap forces to snap the magnetic sensor switch 631 onto the inner wall of the first groove 641, thereby fixing the magnetic sensor switch 631.

[0194] In one embodiment, as Figure 18 , Figure 19 shown, the fourth snap structure 6411 includes a third snap 64111 and a sixteenth abutting portion 64112; at least one third snap 64111 snaps onto one end of the magnetic sensor switch 631, and at least one sixteenth abutting portion 64112 abuts against the opposite end of the magnetic sensor switch 631. Specifically, the fourth snap structure 6411 includes a third snap 64111 and a sixteenth abutting portion 64112; the third snap 64111 and the sixteenth abutting portion 64112 are in corresponding positions. The third snap 64111 is in a bent structure and snaps onto one end of the magnetic sensor switch 631 to restrict the movement of the magnetic sensor switch 631 towards the third snap 64111. The sixteenth abutting portion 64112 abuts against the opposite end of the magnetic sensor switch 631 to restrict the movement of the magnetic sensor switch 631 in the direction away from the sixteenth abutting portion 64112. The magnetic sensor switch 631 is fixed by the third snap 64111 and the sixteenth abutting portion 64112.

[0195] In one embodiment, the first fixing base 640 is provided with a fourth snap 642 for mounting on the storage box 600. Specifically, a fourth snap 642 is provided on each side of the first fixing base 640 and snaps into a fifth slot 6211 provided in a storage box 600 for mounting the first fixing base 640. The fourth snap 642 includes a fifth clamping protrusion 6421 and a third receiving portion 6422. The fifth clamping protrusion 6421 is connected to the side wall of the first fixing base 640 through the third receiving portion 6422. The first fixing base 640 is provided with a fourth through groove 643 to surround the circumferential side of the fifth clamping protrusion 6421 and the two side walls where the third receiving portion 6422 is connected to the fifth clamping protrusion 6421, so as to reduce the resistance of the fourth snap 642 to deformation when the fourth snap 642 snaps into the fifth slot 6211 or is detached from the fifth slot 6211. Further, the fifth clamping protrusion 6421 gradually narrows in the direction towards the fifth slot 6211 to facilitate snapping into the fifth slot 6211.

[0196] In one embodiment, the first fixing base 640 is provided with a first groove 641, and a fourth snap structure 6411 is disposed in the first groove 641. The fourth snap structure 6411 restricts the magnetic sensor switch 631 from detaching from the first groove 641, fixing the magnetic sensor switch 631 in the first groove 641, thereby playing a role in fixing and protecting the magnetic sensor switch 631.

[0197] Furthermore, the first groove 641 is further provided with two seventeenth abutting portions 6412 for respectively abutting against the two side walls of the magnetic sensor switch 631 that are not provided with the fourth snap structure 6411, so as to further fix the two side walls of the magnetic sensor switch 631 that are not provided with the fourth snap structure 6411. The two seventeenth abutting portions 6412 may be the same or different, as long as they have an abutting function.

[0198] In one embodiment, as Figure 15 、 Figure 17 、 Figure 18 shown, the fifth mounting structure 621 is a mounting groove having fifth card slots 6211 provided on both sides respectively; the fourth snaps 642 provided on both sides of the first fixing base 640 are snapped into one of the fifth card slots 6211, so as to detachably connect the first fixing base 640 into the fifth mounting structure 621 provided on the box cover 620.

[0199] In one embodiment, as Figure 14 、 Figure 15 shown, the second box body 610 is provided with a shaft hole 614, and the box cover 620 is provided with a connecting shaft 623, so that the second box body 610 and the box cover 620 can be rotatably connected. The shaft hole 614 of the second box body 610 is away from the open end of the second box body 610.

[0200] In one embodiment, as Figure 15 shown, the second box body 610 is provided with a handle 613 to facilitate opening the storage box 600 with force.

[0201] In one embodiment, as Figure 16 shown, the storage box 600 is flat and occupies a small space; the outer contour of the side of the storage box 600 facing away from the door liner 140 is located in the first recessed portion 1411 of the door liner 140, so as to prevent affecting the closing of the door body on the refrigerator cabinet.

[0202] The door liner 140 is recessed to form a first recessed portion 1411; the storage box 600 is installed on the inner wall of the first recessed portion 1411. The storage box 600 is installed on the inner wall of the first recessed portion 1411. Specifically, both ends of the box cover 620 of the storage box 600 are snapped into the third card slots 14111 provided on the inner wall of the first recessed portion 1411 of the door liner 140 to realize the installation of the storage box 600.

[0203] In one embodiment, as Figure 20As shown, it further includes a shelf 500. The shelf 500 is installed on the inner wall of the first recess 1411 and is disposed above the storage box 600. Sixth clamping protrusions 510 are respectively provided on both sides of the shelf 500 to be clamped into the third card slot 14111 of the door liner 140. The storage box 600 is disposed below the shelf 500. Since opening the storage box 600 requires the rotation between the second box body 610 and the box cover 620, thereby exposing the storage space inside the storage box 600. If the storage box 600 is disposed above the shelf 500, the installation position of the storage box 600 is too high, and when the user needs to use the storage box 600, the stored items may fall during the rotation between the second box body 610 and the box cover 620.

[0204] In one embodiment, as Figure 1 shown, the display door 102 includes a foam door body assembly 100 and a display assembly 200; the foam door body assembly 100 is provided with a foam layer; the display assembly 200 includes a bracket body 210, a display screen 220, a transparent panel 230, and a second control board 240; the display screen 220 is fixed on the bracket body 210 and is electrically connected to the second control board 240; the transparent panel 230 is attached to one side of the bracket body 210; wherein,

[0205] the bracket body 210 is dimensionally matched with the foam door body assembly 100, and the side of the bracket body 210 where the display screen 220 is installed and away from the transparent panel 230 is detachably connected to one side of the door panel body 120 of the foam door body assembly 100.

[0206] As Figure 21 、 Figure 22 shown, the display door 102 includes a foam door body assembly 100 and a display assembly 200. The bracket body 210 of the display assembly 200 is clamped to one side of the door panel body 120 of the foam door body assembly 100. The foam door body assembly 100 includes a door panel body 120, a door liner 140, and a door body door frame; the door panel body 120 and the door liner 140 are oppositely arranged. The door liner 140 is fixed on the side close to the refrigerator body 101 and together with the door body door frame forms a sealed space. The sealed space is provided with a foam layer to provide heat insulation performance.

[0207] As Figure 23 、 Figure 24 shown, the door panel body 120 is provided with a plurality of third fixing seats 122. At least two third fixing seats 122 are respectively located outside the two opposite outer walls of the bracket body 210 and abut against the two opposite outer walls of the bracket body 210 to form opposite abutting forces to limit the shaking of the bracket body 210 in one direction of its plane, thereby realizing the positioning and pre-installation of both sides of the bracket body 210.

[0208] The door panel body 120 further includes an integrally formed thin plate structure 121. The thin plate structure 121 is a sheet metal part and is rectangular in shape. The third fixing seat 122 is arranged on the thin plate structure 121. The third fixing seat 122 further includes a mounting seat 1222, and the first limiting portion 1221 protrudes from the mounting seat 1222. The number of the third fixing seats 122 and their positions on the thin plate structure 121 are set according to the size of the bracket body 210 to adapt to the pre-installation of bracket bodies 210 of different sizes.

[0209] As Figure 28 shown, the first limiting portion 1221 is in a bent structure. The bending direction of the first limiting portion 1221 faces the corresponding mounting part of the bracket body 210. The bending directions of the first limiting portions 1221 of the two third fixing seats 122 that form a relative abutting force are opposite to limit the two opposite outer sides of the bracket body 210. One side wall of the bracket body 210 extends into the cavity formed by the bent structure of the first limiting portion 1221 and the surface of the mounting seat 1222, restricting three surfaces on one side of the bracket body 210. That is, the first limiting portions 1221 of at least two third fixing seats 122 that form a relative abutting force respectively clamp the two opposite side walls of the bracket body 210 to limit the movement of the bracket body 210 in two directions, including restricting the swaying of the bracket body 210 in one direction in the plane where the thin plate structure 121 is located and restricting the movement of the bracket body 210 in the direction away from the thin plate structure 121.

[0210] Further, the inner wall of the bent structure of the first limiting portion 1221 completely abuts against an outer wall of the bracket body 210 away from the thin plate structure 121. That is, the inner wall of the cavity formed by the bent structure of the first limiting portion 1221 and the surface of the mounting seat 1222 closely adheres to an outer wall of the bracket body 210 away from the thin plate structure 121 to firmly restrict the movement of the bracket body 210 in the direction away from the thin plate structure 121.

[0211] There is an assembly gap between the inner wall of the bent structure of the first limiting portion 1221 and the outer wall of the bracket body 210. The bracket body 210 can move slightly along the direction where the two relatively arranged third fixing seats 122 are located between the two relatively arranged third fixing seats 122. After the bracket body 210 is inserted into the bent structure of the third fixing seat 122, there is a small distance between the inner wall on one side of the third fixing seat 122 relative to the bracket body 210 and the bracket body 210 to avoid the third fixing seat 122 being in close contact with the bracket body 210 and increasing the difficulty of clamping for easy clamping. Due to the bent structure of the third fixing seat 122, the two sides of the bracket body 210 are restricted within the bent structure of the third fixing seat 122, and there is only a slight left - right movement, which will not affect the positioning pre - installation.

[0212] As Figure 23As shown, the thin plate structure 121 is provided with a hole 1211; the first limiting portion 1221 extends into the hole 1211, and the mounting seat 1222 is connected to an outer wall of the thin plate structure 121. The mounting seat 1222 completely covers the hole 1211 to seal the hole 1211, which is beneficial for subsequent foaming to prevent foaming overflow. Further, the size of the inner contour of the hole 1211 is larger than the size of the outer contour of the first limiting portion 1221, so that the first limiting portion 1221 can smoothly extend into the hole 1211. The mounting seat 1222 is provided with a plurality of third through holes 12222, and the thin plate structure 121 is provided with fourth through holes 1215 corresponding to the positions of the third through holes 12222. In one embodiment, the third fixing seat 122 is connected to the thin plate structure 121 by sequentially passing rivets through the fourth through holes 1215 and the third through holes 12222. In another embodiment, the third fixing seat 122 is detachably connected to the thin plate structure 121 by sequentially passing screws through the fourth through holes 1215 and the third through holes 12222.

[0213] The third fixing seat 122 is a plastic part with a certain elasticity, which is convenient for pre-assembling the positioning of the bracket body 210 and is not easily damaged.

[0214] As Figure 23 shown, a plurality of third fixing seats 122 are arranged in two columns; the bending directions of the first limiting portions 1221 of the plurality of third fixing seats 122 in the same column are the same, and the bending directions of the first limiting portions 1221 of the plurality of third fixing seats 122 in different columns are opposite. In one embodiment, a plurality of third fixing seats 122 are arranged in two columns and a plurality of rows. The two relatively arranged third fixing seats 122 in different columns are on the same horizontal line, and the arrangement of the plurality of third fixing seats 122 is regular to perform positioning pre-assembly on the bracket body 210. In another embodiment, the two relatively arranged third fixing seats 122 in different columns are not on the same horizontal line and are arranged with a longitudinal offset, which can realize the positioning pre-assembly of the bracket body 210. However, since the arrangement of the plurality of third fixing seats 122 is irregular, it is slightly inconvenient for the installation of the third fixing seats 122. Further, a plurality of third fixing seats 122 are arranged in pairs on the thin plate structure 121.

[0215] In one embodiment, as Figure 23 shown, the number of the third fixing seats 122 is three pairs, and they are respectively arranged in pairs at the top, bottom, and between the top and bottom of one surface of the thin plate structure 121. The two relatively arranged third fixing seats 122 in different columns are on the same horizontal line to perform positioning pre-assembly on several parts of the bracket body 210 respectively.

[0216] In one embodiment, the direction of the column where a plurality of third fixing seats 122 are located is parallel to the longitudinal direction of the thin plate structure 121; as Figure 28As shown, the first limiting portion 1221 is bent in an "L" shape, including a first bent edge 12211 and a second bent edge 12212. The first bent edge 12211 is fixed on the mounting seat 1222. The first bent edge 12211 and the second bent edge 12212 are perpendicular to each other. The first bent edge 12211 is parallel to the longitudinal direction of the thin plate structure 121, so that the first limiting portions 1221 of the relatively arranged third fixing seats 122 limit the longitudinal movement of the bracket body 210 and the movement in the direction away from the thin plate structure 121.

[0217] As Figure 28 shown, the mounting seat 1222 is provided with a positioning post 12221, and the thin plate structure 121 is provided with a positioning hole corresponding to the position of the positioning post 12221. When installing the third fixing seat 122, align the positioning post 12221 and insert it into the corresponding positioning hole to realize the positioning pre-installation of the third fixing seat 122 and the thin plate structure 121, which is convenient for installation.

[0218] As Figure 23 shown, it further includes a first side extrusion strip 170 and a second side extrusion strip 180 respectively fixed on both sides of the thin plate structure 121; the outer sides of the first side extrusion strip 170 and the second side extrusion strip 180 are respectively connected to a first side trim strip 150 and a second side trim strip 160 used to form the two side frames of the door body door frame. The first side extrusion strip 170 and the second side extrusion strip 180 are respectively clamped at both ends of the thin plate structure 121.

[0219] As Figure 23 、 Figure 24 shown, second bent portions 1214 for thickening are respectively provided on both sides of the thin plate structure 121. In one embodiment, the thin plate structure 121 is a sheet metal part, which is easy to be bent. After bending both sides of the thin plate structure 121, the bent edges are attached to a surface of the thin plate structure 121 away from the bracket body 210. The two sides of the thin plate structure 121 are thickened to have a certain thickness, which is convenient for clamping with the first side extrusion strip 170 and the second side extrusion strip 180, so as to avoid increasing the difficulty of clamping alignment due to insufficient thickness on both sides of the thin plate structure 121.

[0220] Since the first-side extrusion strip 170 and the second-side extrusion strip 180 are respectively installed on both sides of the thin plate structure 121 that undergoes bending and thickening treatment, if the fixed connection between the first-side extrusion strip 170 or the second-side extrusion strip 180 and the thin plate structure 121 is at the bending edge of the thin plate structure 121, then a second notch for making way for installation needs to be provided at the second bending part 1214 on this side; if the fixed connections between the first-side extrusion strip 170 and the second-side extrusion strip 180 on both sides and the thin plate structure 121 are both at the corresponding bending edges of the thin plate structure 121, then second notches for making way for installation need to be provided at the second bending parts 1214 on both sides. That is, at least one side of the second bending part 1214 is provided with a second notch for making way for installation. In an embodiment, the first-side extrusion strip 170 and / or the second-side extrusion strip 180 are connected to the thin plate structure 121 by rivets. After the rivets extend into the corresponding through holes from the side where the bracket body 210 is located and are fixed, the diameter of the end of the rivet away from the bracket body 210 will increase. In order to prevent the bending edges on both sides of the thin plate structure 121 from blocking the increase in diameter after the rivets are fixed, the size of the second notch is based on not affecting the increase in diameter of the local part during rivet fixing.

[0221] As Figure 23 shown, the first-side trim strip 150 clamps the first-side extrusion strip 170 to limit the front-back movement of the first-side extrusion strip 170. The second-side trim strip 160 clamps the second-side extrusion strip 180 to limit the front-back movement of the second-side extrusion strip 180.

[0222] As Figure 23 shown, both the first-side extrusion strip 170 and the second-side extrusion strip 180 are asymmetric structures for anti-fooling, so that installers can confirm which side of the door panel body 120 they are installed on during installation.

[0223] As Figure 23 、 Figure 24 shown, the thin plate structure 121 is provided with a first anti-fooling part 1213 for indicating the installation direction, for distinguishing the top or bottom direction of the thin plate structure 121 and / or for distinguishing the front or back of the thin plate structure 121. In an embodiment, the first anti-fooling part 1213 is a triangular figure, and the sharp angle of the triangle is used to indicate the top or bottom direction of the thin plate structure 121, and the surface where the triangular figure is located is used to indicate the front or back of the thin plate structure 121. In an embodiment, the first anti-fooling part 1213 is a triangular hole, and the sharp angle of the triangle is used to indicate the top or bottom direction of the thin plate structure 121, but it does not have the function of indicating the front or back of the thin plate structure 121.

[0224] As Figure 23As shown, the hole 1211 is provided with a second anti-misassembly part 12111 for indicating the installation direction of the third fixing seat 122. In one embodiment, the first limiting part 1221 is in a bent structure, and the second anti-misassembly part 12111 is used to indicate the bending direction of the bent structure of the first limiting part 1221 when the third fixing seat 122 is installed, which is convenient for assembly and improves the assembly efficiency. In one embodiment, the second anti-misassembly part 12111 is a corner structure in the hole 1211, and the corner structures in the two holes 1211 corresponding to the two oppositely arranged third fixing seats 122 are opposite in position to indicate that the bending directions of the bent structures of the two oppositely arranged third fixing seats 122 are opposite. Further, the first limiting part 1221 is provided with a third anti-misassembly part 12213 corresponding to the second anti-misassembly part 12111. The shape and structure of the third anti-misassembly part 12213 are the same as those of the second anti-misassembly part 12111, that is, a corner structure on the first limiting part 1221. The corner structure on the first limiting part 1221 matches the corner structure on the hole 1211 to indicate the installation direction of the third fixing seat 122 relative to the corresponding hole 1211.

[0225] In one embodiment, as Figure 29 shown, the bracket body 210 is a frame structure, and the display screen 220 is fixed in the frame of the bracket body 210.

[0226] Further, the bracket body 210 includes a fixed bracket 212 and an extension bracket; wherein,

[0227] The fixed bracket 212 is a frame structure, and the display screen 220 of the display screen assembly 200 is fixed in the frame of the fixed bracket 212; the fixed bracket 212 is connected to at least one extension bracket to form an installation structure matching the foaming door body assembly 100. The number of extension brackets and / or the size of one or several extension brackets are changed to change the size of the bracket body 210.

[0228] It should be understood that the installation structure of the foaming door body assembly 100 described above includes changing the size of the bracket body 210 to form different installation structures for cooperating with the foaming door body assembly 100.

[0229] In one embodiment, the fixed bracket 212 and the extension bracket are spliced with each other and are easily detachable.

[0230] In one embodiment, the fixed bracket 212 and the extension bracket are seamlessly connected, and the fixed bracket 212 and the extension bracket are closely abutted against each other without easy shaking. In order to avoid the existence of a gap between the fixed bracket 212 and the extension bracket, which affects the subsequent bonding of the transparent panel 230 of the display screen assembly 200.

[0231] The splicing method includes horizontal splicing, vertical splicing or a combination of the two. The plurality of expansion brackets are the same or different from each other; that is, the structures of the plurality of expansion brackets can be the same or different, and the sizes can be the same or different, depending on production requirements.

[0232] In one embodiment, a plurality of expansion brackets are connected to each other as a whole, and then connected to the fixed bracket 212 .

[0233] In one embodiment, a plurality of extension brackets and fixed brackets 212 are spliced ​​longitudinally in sequence, and the size of any one or several extension brackets is changed, and / or the number of extension brackets is changed, so that the longitudinal size of the bracket body 210 formed by the longitudinal splicing of a plurality of brackets can be changed. Similarly, the transverse size of the bracket body 210 formed by the transverse splicing of a plurality of extension brackets and fixed brackets 212 can be changed. In one embodiment, the bracket body 210 is formed by the combination of transverse splicing connection and longitudinal splicing connection, and the longitudinal size and / or longitudinal size of the bracket body 210 can be changed by changing the size of any one or several extension brackets and / or the number of extension brackets. That is, in actual production, if the size of the display screen 220 remains unchanged, the size of the fixed bracket 212 remains unchanged, and there is no need to re-produce; if it is necessary to meet the requirements of door bodies of different sizes, the size of any one or several extension brackets and / or the number of extension brackets can be changed. Moreover, the splicing connection is easy to disassemble, the extension bracket structure is simple, the production process is short, the replacement cost is low, and it is convenient to adjust the size of the bracket body 210.

[0234] like Figure 21 As shown, the outer contours of the fixed bracket 212 and the transparent panel 230 of the plurality of extended brackets facing the display screen assembly 200 are in the same plane; the outer contours of the fixed bracket 212 and the transparent panel 230 of the plurality of extended brackets facing away from the display screen assembly 200 are in the same plane. That is, the front and back surfaces of the bracket body 210 are flat, which is conducive to the engagement between the bracket body 210 and the door panel body 120 of the foam door body assembly 100 and the bonding between the transparent panel 230 and the bracket body 210. In one embodiment, the outer surface contour of the transparent panel 230 of the bracket body 210 facing the display screen assembly 200 is flush with the outer contours of the first side trim strip 150 and the second side trim strip 160 of the foam door body assembly 100, so as to stably fix the transparent panel 230.

[0235] In one embodiment, the fixed bracket 212 is connected to the extended bracket via a buckle, which is engaged with a slot via the buckle, and the fixed bracket and the extended bracket or several extended brackets are detachable.

[0236] In one embodiment, the fixed bracket 212 is connected to the extended bracket by a fastener, and the fixed bracket is fixedly connected to the extended bracket or several extended brackets, and the connection is firm. Further, the fastener is a screw.

[0237] likeFigure 29 , Figure 30 As shown, between the fixedly connected fixed bracket and the extension bracket or a plurality of extension brackets that are spliced and connected, they are fixedly connected through the connecting structure 218 to form the bracket body 210 as a stable whole, facilitating the subsequent installation of the door body. In an embodiment, the connecting structure 218 includes a first connecting portion 2181 and a second connecting portion 2182 that are mutually engaged. The first connecting portion 2181 and the second connecting portion 2182 are respectively arranged on one of the opposite outer walls of the two brackets that are spliced and connected. The first connecting portion 2181 is a positioning protrusion, and the second connecting portion 2182 is a positioning groove that restricts the movement of the first connecting portion 2181 in at least four directions. The cross-sections of both the first connecting portion 2181 and the second connecting portion 2182 are trapezoidal. The first connecting portion 2181 and the second connecting portion 2182 are respectively provided with through holes. The second connecting portion 2182 in the form of a positioning groove is provided with a side wall along the extending direction of the extension bracket to form the side wall structure of the through hole. Further, the extending side wall is flush with one surface of the extension bracket; the first connecting portion 2181 and the second connecting portion 2182 are fixedly connected by screws in the direction facing or facing away from the transparent panel 230. The first connecting portion 2181 and the second connecting portion 2182 simultaneously play the roles of positioning and fixing, and do not affect the flatness of one side of the bracket body 210 facing or facing away from the transparent panel 230. Further, the first connecting portion 2181 in the form of a positioning protrusion gradually expands along its extending direction, and the second connecting portion 2182 in the form of a positioning groove is an opening on the side away from or close to the door panel body. The first connecting portion 2181 is placed into the second connecting portion 2182 in the form of a positioning groove from the opening of the second connecting portion 2182, and the first connecting portion 2181 is not easily detached from the second connecting portion 2182, facilitating subsequent fixing by screws. In an embodiment,

[0238] Further, the fixed bracket 212 and the connected extension bracket are abutted through the positioning groove and the positioning protrusion. In an embodiment, as Figure 29 , Figure 31 shown, the fixed bracket 212 and the connected extension bracket are first pre-assembled and limited by abutting, reducing the assembly difficulty. Further, they are abutted through the positioning groove and the positioning protrusion. The positioning protrusion gradually narrows along its extending direction. In an embodiment, the cross-section of the positioning groove and the cross-section of the positioning protrusion are both triangular. The triangular tip of the positioning protrusion first extends into the positioning groove until the outer contour of the part of the positioning protrusion extending into the positioning groove is in close contact with the inner contour of the positioning groove; due to the small volume of the triangular tip of the positioning protrusion, it can be quickly extended into the positioning groove, and finally positioning pre-assembly is achieved. The inner contour of the positioning groove wraps the outer contour of the positioning protrusion extending into the positioning groove, so that after the positioning protrusion extends into the positioning groove, it is firmly fixed and will not shake left and right. In an embodiment, as Figure 29As shown in the figure, the bracket body 210 includes three brackets that are longitudinally spliced and connected in sequence, that is, the number of extended brackets is two, including the first extended bracket 211 and the second extended bracket 213; that is, the bracket body 210 includes the first extended bracket 211, the fixed bracket 212, and the second extended bracket 213 that are longitudinally spliced and connected in sequence; the display screen 220 is fixed within the fixed bracket 212 having a frame structure. Increase or decrease the first extended bracket 211 and / or the second extended bracket 213; or change the size of the first extended bracket 211 and / or the second extended bracket 213 to change the longitudinal size of the bracket body 210. Further, the producer can set several conventional sizes of the bracket body 210, that is, the bracket body 210 includes the first extended bracket 211, the fixed bracket 212, and the second extended bracket 213 that are spliced and connected in sequence; or, the bracket body 210 includes the first extended bracket 211, the fixed bracket 212 that are spliced and connected in sequence; or, the bracket body 210 includes the fixed bracket 212, the second extended bracket 213 that are spliced and connected in sequence; or, the bracket body 210 includes the fixed bracket 212. By increasing or decreasing the first extended bracket 211 and / or the second extended bracket 213, the size of the bracket body 210 can be quickly extended according to production requirements. Further, the first extended bracket 211 and the second extended bracket 213 may or may not be the same.

[0239] In one embodiment, as Figures 29 to 31 shown, the first extended bracket 211 is provided with a fifth abutting portion 2111 on the outer wall facing the fixed bracket 212, the second extended bracket 213 is provided with an eighth abutting portion 2131 on the outer wall facing the fixed bracket 212, and the two outer walls of the fixed bracket 212 are provided with a sixth abutting portion 2121 and a seventh abutting portion 2122 that respectively abut against the fifth abutting portion 2111 and the eighth abutting portion 2131. Further, the fifth abutting portion 2111 and the eighth abutting portion 2131 are positioning protrusions, which are triangular; the sixth abutting portion 2121 and the seventh abutting portion 2122 are positioning grooves respectively matching the fifth abutting portion 2111 and the eighth abutting portion 2131, which are triangular.

[0240] Further, the top end and / or the bottom end of the bracket body 210 is provided with a third mounting portion 217, and the third mounting portion 217 is provided with a mounting hole to be fixedly connected to the upper end cover body 110 and / or the lower end cover body 130 by screws, so as to further fix the bracket body 210 on the foamed door body assembly 100 and stabilize the splicing connection between several brackets. As Figure 26 shown, the third mounting portion 217 is arranged at the bottom end of the bracket body 210 to be fixedly connected to the lower end cover body 130.

[0241] As Figure 21 、 Figure 23As shown, in one embodiment, the door frame of the foamed door body assembly 100 includes an upper end cover body 110 and a lower end cover body 130 that are respectively used to form the top structure and the bottom structure of the door frame of the door body; the upper end cover body 110 and the lower end cover body 130 respectively press against the top and the bottom of the bracket body 210.

[0242] As Figure 21 , Figure 22 shown, in one embodiment, the first bending portion 1123 provided on the second cover body 112 is simultaneously used to seal the assembly gap between the transparent panel 230 of the display screen assembly 200 and the first cover body 111, so as to form a sealing structure between the transparent panel and the door frame of the foamed door body assembly 100 and avoid dust accumulation. Further, both sides of the first bending portion 1123 are respectively attached to the inner side of the transparent panel 230 of the display screen assembly 200 and one side of the first cover body 111. A first abutting portion 1125 is provided at one end of the first bending portion 1123 relative to the bracket body 210, and abuts against one end of the bracket body 210 to press against the top of the bracket body 210.

[0243] In one embodiment, as Figure 23 shown, a plurality of second abutting portions 1311 are provided at one end of the lower end cover body 130 relative to the bracket body 210 to press against the bottom of the bracket body 210.

[0244] The bracket body 210 abuts against the upper end cover body 110 and the lower end cover body 130. Further, they abut against each other through a positioning groove and a positioning protrusion. The positioning protrusion extends into the positioning groove and is positioned by the positioning groove to achieve the splicing connection between adjacent brackets, or to achieve the positioning connection of the upper end cover body 110 and the lower end cover body 130 to the top and the bottom of the bracket body 210 respectively.

[0245] The positioning protrusion gradually narrows along its extending direction. In one embodiment, the cross-section of the positioning groove and the cross-section of the positioning protrusion are both triangular. The triangular tip of the positioning protrusion first extends into the positioning groove until the outer contour of the part of the positioning protrusion extending into the positioning groove is closely attached to the inner contour of the positioning groove; due to the small volume of the triangular tip of the positioning protrusion, it can be quickly extended into the positioning groove, and finally the positioning pre-installation is realized.

[0246] The inner contour of the positioning groove wraps the outer contour of the positioning protrusion extending into the positioning groove, so that after the positioning protrusion extends into the positioning groove, it is firmly fixed and will not shake left and right.

[0247] As Figure 21As shown, in one embodiment, the second abutting portion 1311 and the third abutting portion 215 are positioning grooves, and the first abutting portion 1125 and the fourth abutting portion 216 are positioning protrusions. The first abutting portion 1125 of the upper end cover body 110 is inserted into the third abutting portion 215 at the top of the bracket body 210, and the second abutting portion 1311 of the lower end cover body 130 wraps the fourth abutting portion 216 at the bottom of the bracket body 210 to perform positioning pre-assembly on the top and bottom of the bracket body 210 and restrict the longitudinal movement of the bracket body 210. In addition, due to the cooperation of the positioning groove and the positioning protrusion, the lateral movement of the bracket body 210 is further restricted. By fitting the positioning protrusion into the positioning groove for abutting, the first abutting portion 1125 and the second abutting portion 1311 respectively press the top and bottom of the bracket body 210, and at the same time, it also has a positioning and auxiliary installation function, reducing the assembly difficulty. The third installation portion 217 protrudes from the lower end of the bracket body 210, and the third installation portion 217 extends into the groove at the corresponding installation position of the lower end cover body 130. Screws are sequentially passed through the installation holes in the groove at the installation position of the lower end cover body 130 and the installation holes on the third installation portion 217 to fixedly connect the bracket body 210 and the lower end cover body 130 to restrict the downward longitudinal movement of the bracket body 210. The first cover body 111 of the upper end cover body 110 is fixedly connected to the door panel body 120. The bracket body 210 is snapped into the corresponding first limiting portion 1221 provided on the door panel body 120 from the side where the top of the door panel body 120 is located. The first abutting portion 1125 of the second cover body 112 abuts against the third abutting portion 215 at the top of the bracket body 210, and the first cover body 111 and the second cover body 112 are fixedly connected by screws to restrict the upward longitudinal movement of the bracket body 210.

[0248] As Figures 29 to 31 As shown, at least one clamping structure 214 is respectively provided on two opposite sides of the bracket body 210 to engage with the first limiting portion 1221 on the door panel body 120. Further, at least one clamping structure 214 is respectively provided on two opposite sides of the fixing bracket 212 to stably position the fixing bracket 212 on the door panel body 120 so that it is not easily separated from the door panel body 120, thereby protecting the display screen 220. Further, at least one clamping structure 214 is respectively provided on two opposite sides of the fixing bracket 212 and a plurality of extension brackets to stably position the bracket body 210 on the door panel body 120.

[0249] The snap - fit structure 214 includes a snap - in portion 2141 and a second limiting portion 2142. The snap - in portion 2141 extends into the cavity formed between the bent first limiting portion 1221 and the thin plate surface of the door panel body 120. The bending directions of the first limiting portions 1221 on both sides of the bracket body 210 are opposite to limit the lateral movement of the bracket body 210 and the movement in the direction away from the door panel body 120. The second limiting portion 2142 abuts against the outer wall of the first limiting portion 1221 to prevent the snap - in portion 2141 from detaching from the first limiting portion 1221, thus achieving snap - fit. In an embodiment, the number of snap - fit structures 214 on the outer walls of the two opposite sides of the bracket body 210 is several, and the structures or dimensions of the several snap - fit structures 214 on the same side wall of the bracket body 210 can be the same or different from each other.

[0250] In an embodiment, the bracket body 210 includes a first extended bracket 211, a fixed bracket 212, and a second extended bracket 213 that are longitudinally spliced and connected in sequence. The number of snap - fit structures 214 is six, and one snap - fit structure 214 is provided on each side of the first extended bracket 211, the fixed bracket 212, and the second extended bracket 213. The structures and dimensions of the first snap - fit structure 2143, the second snap - fit structure 2144, and the third snap - fit structure 2145 on the first extended bracket 211, the fixed bracket 212, and the second extended bracket 213 are slightly different, but the snap - fit effects of the first snap - fit structure 2143, the second snap - fit structure 2144, and the third snap - fit structure 2145 on the corresponding first limiting portions 1221 are the same.

[0251] Further, after the several snap - in portions 2141 respectively extend into the cavities formed between the corresponding first limiting portions 1221 and the thin plate surface of the door panel body 120, the corresponding second limiting portions 2142 exactly abut against the outer walls of the corresponding first limiting portions 1221, so that the several first limiting portions 1221 on the door panel body 120 simultaneously exert a force on the bracket body 210 towards the second limiting portion 2142, achieving a stable snap - fit.

[0252] The snap - in portion 2141 is gradually narrowed and thinned in the direction away from the second limiting portion 2142, so that the snap - in portion 2141 can smoothly extend into the cavity formed between the first limiting portion 1221 and the thin plate surface of the door panel body 120, so as to quickly achieve snap - fit.

[0253] Further, an assembly gap is provided between the outer wall of the engaging portion 2141 of the bracket body 210 and the inner wall corresponding to the first limiting portion 1221, so that the engaging portion 2141 can smoothly extend into the cavity formed between the first limiting portion 1221 and the thin plate surface of the door panel body 120. The engaging structure 214 can slightly move left and right in the cavity formed between the corresponding first limiting portion 1221 and the thin plate surface of the door panel body 120, which is convenient for engagement and does not affect the function of the first limiting portion 1221 in restricting the lateral movement of the bracket body 210 and the movement in the direction away from the door panel body 120.

[0254] As Figure 21 , Figure 29 , Figure 30 shown, at least two opposite inner walls of the frame body of the fixing bracket 212 are convexly provided with ninth abutting portions 2123 for abutting against the back surface of the display screen 220, and the thickness of the ninth abutting portion 2123 is less than the thickness of the frame body of the fixing bracket 212. The outer contour of the ninth abutting portion 2123 and the outer contour of the display screen 220 are both located within the corresponding bracket frame. In an embodiment, the cross-section of the display screen 220 and the inner contour of the bracket frame for fixing the display screen are both rectangular; one end of each of the two inner walls of the frame body of the fixing bracket 212 is respectively provided with a ninth abutting portion 2123, and a ninth abutting portion 2123 is respectively provided near the corners of the other two inner walls of the frame body of the fixing bracket 212. The four ninth abutting portions 2123 respectively abut against the four corners of an outer surface of the display screen 220 to stably abut against the display screen 220. As Figure 21 , Figure 29 shown, in an embodiment, the ninth abutting portion 2123 is provided on the inner wall of the frame body of the fixing bracket 212.

[0255] The outer surface of the bracket body 210 facing the transparent panel 230 protrudes from or is flush with the outer surface of the first limiting portion 1221 facing the transparent panel 230, so as to prevent the outer surface of the first limiting portion 1221 facing the transparent panel 230 from protruding from the outer surface of the bracket body 210 facing the transparent panel 230, which may affect the fitting between the transparent panel 230 adhered to the outer surface of the bracket body 210 and the frame of the foam door body assembly 100 when the display screen assembly 200 is clamped on one side of the foam door body assembly 100.

[0256] As Figure 29As shown, the bracket body 210 is provided with a giving part 219 on both sides for allowing the bracket body 210 to engage with the first limiting part 1221. The giving parts 219 on both sides of the bracket body 210 are aligned with the first limiting part 1221 corresponding to the position on the door panel body 120, and the bracket body 210 moves down for engagement, so that the bracket body 210 and the door panel body 120 are engaged. In one embodiment, the number of the clamping structure 214 and the first limiting part 1221 are both six, and the number of the giving parts 219 on both sides of the bracket body 210 is also six, so as to allow the clamping structure 214 to be clamped into the first limiting part 1221 from above.

[0257] In one embodiment, if Figure 22 As shown, the first cover body 111 is provided with a drainage groove 1111. A drainage port 11111 is provided on one side of the drainage groove 1111; the bottom surface of the drainage groove 1111 is a slope, which gradually becomes shorter toward the drainage port 11111, and the drainage port 11111 is located on the side where the lower end of the slope is located to guide water to the drainage port 11111. The second cover body 112 seals the surrounding side of the drainage groove 1111, and a gap is left corresponding to the drainage port 11111 for drainage of the drainage groove 1111. Based on the principle that water flows to lower places, the drainage groove 1111 promptly removes water that may accumulate on the upper surface of the upper end cover body 110.

[0258] The first cover body 111 is connected to the second cover body 112 by a plurality of screws; the second cover body 112 is provided with a plurality of second through holes 1122, and the first cover body 111 is provided with a plurality of threaded holes corresponding to the second through holes 1122, the bottom of the threaded holes is closed, and the plurality of threaded holes and the plurality of second through holes correspond to each other one by one for screws to pass through for screw connection.

[0259] The first cover body 111 has a side wall structure extending in a direction away from the second cover body 112 so as to be connected to the door panel and door body 120, the door liner 140, the first side trim 150, and the second side trim 160 respectively to play a fixing and protective role.

[0260] like Figure 22 As shown, a side wall of the first cover 111 is provided with a plurality of fourth recessed portions 1119, and the bottom end of the fourth recessed portion 1119 and the side wall of the first cover 111 form a first engaging notch 11191 for engaging the door panel body 120 of the door body; the door panel body 120 is engaged in the first engaging notch 11191, and is supported by the inner wall of the first cover 111 and the outer wall of the fourth recessed portion 1119, so as to limit the movement of the door panel body 120 in the front-rear direction. The top end of the door panel body 120 is supported against the inner wall of the first engaging notch 11191, so as to limit the upward movement of the door panel body 120. Because the door panel body 120 is limited, it is convenient for accurate installation. The width of the first engaging notch 11191 is equal to or slightly larger than the thickness of the door panel body 120, so as to facilitate the top end of the door panel body 120 to engage in the first engaging notch 11191.

[0261] As Figure 22 shown, the first cover body 111 is provided with first engaging protrusions 1117 on two opposite side walls thereof for engagingly connecting with the first side trim 150 and the second side trim 160 respectively; the corresponding side trims are provided with engaging grooves for engagingly connecting with the first engaging protrusions 1117 to achieve the engaging connection. The structures of the first engaging protrusions 1117 on both sides of the first cover body 111 may be the same or different, as long as the engaging connection can be achieved.

[0262] As Figure 22 shown, both ends of the second cover body 112 are provided with second engaging protrusions 1124 for engagingly connecting with the first side trim 150 and the second side trim 160 respectively, which are used to form the two side frames of the door frame of the door body. The corresponding side trims are provided with engaging grooves for engagingly connecting with the second engaging protrusions 1124 to achieve the engaging connection. The second cover body 112 is further fixed to the side trims through the engaging connection of the second engaging protrusions 1124, thereby improving the installation firmness of the second cover body 112.

[0263] As Figure 22 shown, the first cover body 111 is provided with a plurality of fixing parts 1118 for connecting with the door panel body 120. The fixing parts 1118 are provided with through holes for fixedly connecting with the door panel body 120 through screw connection.

[0264] As Figure 25 shown, the lower end cover body 130 includes a bottom plate 131. A plurality of second abutting parts 1311 and a plurality of first mounting parts 1312 are convexly provided on a surface of the bottom plate 131 opposite to the bracket body 210. The first mounting parts 1312 are provided with first mounting holes; a plurality of second abutting parts 1311 respectively abut against one end of the bracket body 210 to achieve the pressing and positioning pre-assembly of one end of the bracket body 210 relative to the lower end cover body 130; a plurality of first mounting parts 1312 are fixedly connected with one end of the bracket body 210 through the first mounting holes.

[0265] As Figure 25 shown, the lower end cover body 130 is disposed at the bottom end of the foamed door body assembly 100. The lower end cover body 130 further includes four side walls, and the four side walls are respectively vertically disposed on a surface of the bottom plate 131 opposite to the side where the bracket body 210 is located. In one embodiment, since most door bodies are rectangular parallelepiped structures, the adjacent side walls are perpendicular to each other to be applicable to common door bodies.

[0266] As Figure 25 shown, the height by which the first mounting part 1312 protrudes from the bottom plate 131 is less than or equal to the height by which the second abutting part 1311 protrudes from the bottom plate 131, so as to avoid interfering with the abutting of the second abutting part 1311 and the fourth abutting part 216, and at the same time reduce the depth of the first mounting hole on the first mounting part 1312, facilitating screw fixing.

[0267] As shown Figure 25 in the figure, a fixing plate 1313 protrudes from one side of the bottom plate 131 relative to the bracket body 210. The fixing plate 1313 is in the structure of a thin plate.
