[0002] Cold storage compartments are common equipment in daily life. Especially during picnics, camping trips, long journeys, and food delivery, cold storage compartments effectively maintain the temperature and freshness of food even in the event of a power outage. However, existing cold storage compartments typically have the following problems:

[0003] First, existing refrigerator compartment sealing structures are typically fixed and bulky, making them difficult to store when not in use and occupying considerable space. Second, traditional refrigerator compartment sealing structures often lack convenient folding and unfolding mechanisms, making them inconvenient to transport and carry. Furthermore, the sealing performance of existing refrigerator compartment sealing structures is difficult to guarantee, easily leading to cold air leakage, affecting refrigeration efficiency, and increasing energy consumption.

[0059] Example 1

[0060] See Figures 1 to 9 This application provides a foldable rigid refrigerator compartment sealing structure 2, which is disposed on the upper part of the cabinet 1. The inner cavity of the foldable rigid refrigerator compartment sealing structure 2 is connected to the refrigeration system in the cabinet 1 so that the refrigeration system provides refrigeration to the foldable rigid refrigerator compartment sealing structure 2, including:

[0061] The foldable rigid cold storage compartment sealing structure 2 is a foldable structure made of insulation board.

[0062] The insulation board consists of an outer surface layer and an inner surface layer made of aluminum sheet, and an intermediate layer made of XPS extruded polystyrene board, with the intermediate layer located between the outer surface layer and the inner surface layer.

[0064] Specifically, the foldable rigid refrigerator compartment sealing structure 2 has external dimensions of 990mm×770mm×415mm, an effective volume of 515L, a temperature adjustment range of -10℃~5℃, and a total weight of approximately 29.7kg.

[0065] The insulation board includes an upper plate 21 and a lower plate 22. A sealing structure door 23 is provided at one end of the upper plate 21 and the lower plate 22 respectively. A first back plate 24 and a second back plate 25 hinged to the first back plate 24 are provided at the other end of the upper plate 21 and the lower plate 22 relative to the sealing structure door 23. The second back plate 25 is hinged to the lower plate 22. A first side plate 26 and a second side plate 27 hinged to the first side plate 26 are symmetrically provided on the other two sides of the lower plate 22 and the upper plate 21. The upper end of the first side plate 26 is hinged to the upper plate 21, and the end of the first side plate 26 near the sealing structure door 23 is hinged to the sealing structure door 23. The lower end of the second side plate 27 is hinged to the lower plate 22, and the end of the second side plate 27 near the sealing structure door 23 is hinged to the sealing structure door 23.

[0066] For example, there are two sealing structure doors 23, which are symmetrically arranged between the lower plate 22 and the upper plate 21.

[0067] The foldable rigid refrigerator compartment sealing structure 2 also includes a gap detection system, which is located on the inside of the first back plate 24 near the second back plate 25, and is used to detect the gaps in the door of the sealing structure door 23.

[0070] Each of the first hinge 29 has an embedded aluminum alloy plate inside to enhance the connection strength of the first hinge 29.

[0071] The interior of each second hinge 210 has an embedded aluminum alloy plate to enhance the connection strength of the second hinge 210.

[0072] It should be noted that the first hinge 29 may also use a rivet with a foldable structure or other foldable structure; the second hinge 210 may also use a rivet with a detachable structure or other detachable structure.

[0073] The connection is aesthetically pleasing and durable, achieved by using the first hinge 29 and the second hinge 210. At the same time, multiple folds do not affect the strength and tightness of the foldable rigid refrigerator compartment sealing structure 2.

[0074] In one embodiment, a first hinge 29 between the second back plate 25 and the lower plate 22 is disposed on the inner side of the connection between the second back plate 25 and the lower plate 22, and a first hinge 29 between the first back plate 24 and the second back plate 25 is disposed on the outer side of the connection between the first back plate 24 and the second back plate 25, so that when the foldable rigid refrigerator compartment sealing structure 2 is folded, the second back plate 25 folds toward the inner cavity of the foldable rigid refrigerator compartment sealing structure 2, and the first back plate 24 folds toward the opposite direction of the inner cavity of the foldable rigid refrigerator compartment sealing structure 2.

[0075] In one embodiment, a first hinge 29 between the second side plate 27 and the lower plate 22 is disposed on the inner side of the connection between the second side plate 27 and the lower plate 22, a first hinge 29 between the first side plate 26 and the second side plate 27 is disposed on the outer side of the connection between the first side plate 26 and the second side plate 27, and a first hinge 29 between the first side plate 26 and the upper plate 21 is disposed on the inner side of the connection between the first side plate 26 and the upper plate 21, so that when the foldable rigid refrigerator compartment sealing structure 2 is folded, the second side plate 27 folds toward the inner cavity of the foldable rigid refrigerator compartment sealing structure 2, and the first side plate 26 folds toward the opposite direction of the inner cavity of the foldable rigid refrigerator compartment sealing structure 2.

Figure 4As shown; place the left and right doors smoothly on the folded upper panel 21, with both doors facing the same direction and centered. Use two 2-meter elastic straps and two 2.5-meter elastic straps to securely fix the foldable rigid refrigerator compartment sealing structure 2 to the cabinet 1 from the front and back and left and right directions. Folding is complete.

[0077] When unfolding the sealed door 23, untie all four elastic bands in sequence and remove the top sealed door 23 from its folded state for later use; tighten the refrigerator compartment handle 211 on the top of the folded upper panel 21, and push upwards to unfold the first side panel 26, the second side panel 27, and the upper panel 21 to... Figure 5 State; Pull the refrigerator compartment handle 211 of the folded upper second back panel 25 tightly, and slowly exert force outward to unfold the second back panel 25 to a flat state.

Pull in the refrigerator compartment handle 211 of the sealing structure door 23, and at the same time slowly close the left and right doors to the closed state, close the door latch, and the unfolding is complete.

[0078] See Figure 7 In one embodiment, a gap sealing structure 28 is provided between the first side plate 26 and the upper plate 21.

[0079] It should be noted that, in addition to the gap sealing structure 28 provided between the first side plate 26 and the upper plate 21, a gap sealing structure 28 is provided between the first back plate 24 and the second back plate 25; a gap sealing structure 28 is provided between the second back plate 25 and the lower plate 22; a gap sealing structure 28 is provided between the first side plate 26 and the second side plate 27; and a gap sealing structure 28 is provided between the second side plate 27 and the lower plate 22.

[0080] In one embodiment, the gap sealing structure 28 includes a first sealing strip 281 and a second sealing strip 282. The first sealing strip 281 is disposed on the upper plate 21 at the connection between the first side plate 26 and the upper plate 21, and the second sealing strip 282 is disposed on the first side plate 26 at the connection between the first side plate 26 and the upper plate 21.

[0081] It should be noted that the above embodiment describes the connection relationship of the gap sealing structure 28 provided between the first side plate 26 and the upper plate 21. The gap sealing structures 28 between the first back plate 24 and the second back plate 25, the second back plate 25 and the lower plate 22, the first side plate 26 and the second side plate 27, and the second side plate 27 and the lower plate 22 also have similar connection relationships. The first sealing strip 281 is provided at one of the connection points of the two connected plates, and the second sealing strip 282 is provided at the other connection point of the two connected plates. The connection relationship between other structures included in the first sealing strip 281 and the second sealing strip 282 and the plates is also applicable to the description here.

[0082] See Figure 7 and Figure 8 In one embodiment, the first sealing strip 281 includes a first sealing fixing component 2811 and two first sealing components 2812.

[0083] Two first sealing components 2812 are connected to the first sealing fixing component 2811.

[0084] The second sealing strip 282 has a horizontal "T" shaped structure, including a second sealing component 2821, a second sealing fixing component 2822, and a first side sealing component 2823; one end of the second sealing component 2821 is connected to the middle of the first side sealing component 2823, and the other end is provided with a first protrusion 2824. The middle of the second sealing component 2821 is connected to the second sealing fixing component 2822, and a second protrusion 2825 is also provided in the middle position of the second sealing component 2821.

[0085] The first sealing and fixing component 2811 is fixedly connected to the upper plate 21.

[0086] The second sealing and fixing component 2822 is fixedly connected to the first side plate 26.

[0087] In one embodiment, the first sealing component 2812 is an arc-shaped structure that bends toward the first sealing fixing component 2811; the first protrusion 2824 is an arc-shaped structure that bends toward the second protrusion 2825, and the second protrusion 2825 is an arc-shaped structure that bends toward the first protrusion 2824; when the foldable rigid refrigerator compartment sealing structure 2 is fully unfolded, the two first sealing components 2812 and the second protrusion 2825 divide the connection between the upper plate 21 and the first side plate 26 into multiple sealing areas, so as to seal the connection between the upper plate 21 and the first side plate 26 multiple times, thereby forming a sealing area with three layers of cold bridges to prevent the foldable rigid refrigerator compartment sealing structure 2 from escaping or leaking cold.

[0088] For example, the first sealing component 2812 is an arc-shaped structure that bends toward the first sealing fixing component 2811, which increases the elastic deformation space of the first sealing strip 281 and improves the double-layer sealing effect.

[0089] For example, the first protrusion 2824 is an arc-shaped structure that bends toward the second protrusion 2825. When the second sealing strip 282 is deformed by pressure, the first protrusion 2824 can be deformed on the inner side of the arc, which has better sealing performance.

[0090] For example, the second protrusion 2825 is an arc-shaped structure that bends toward the first protrusion 2824, which makes the unfolding process smoother and more seamless when the foldable rigid refrigerator compartment sealing structure 2 is unfolded.

[0091] In one embodiment, the first side sealing member 2823 is fitted to the outside of the connection between the upper plate 21 and the first side plate 26 so as to seal the connection between the upper plate 21 and the first side plate 26 when the foldable rigid refrigerator compartment sealing structure 2 is unfolded.

[0092] For example, the first side sealing component 2823 fits against the outer side of the connection between the upper plate 21 and the first side plate 26, ensuring that after the foldable rigid refrigerator compartment sealing structure 2 is unfolded, the first sealing strip 281 can fit tightly against the outer side of the foldable rigid refrigerator compartment sealing structure 2, thus both covering the gap at the connection and ensuring the sealing effect at the connection.

[0093] In one embodiment, a plurality of spring latches 212 are provided on the first back plate 24 near the connection between the upper plate 21 and the first back plate 24, a plurality of spring latches 212 are provided on the first back plate 24 near the connection between the first back plate 24 and the first side plate 26, and a plurality of spring latches 212 are provided on the second back plate 25 near the connection between the second back plate 25 and the second side plate 27. When the foldable rigid refrigerator compartment sealing structure 2 is fully unfolded, the spring latches 212 are used to fix the first back plate 24, the second back plate 25, the first side plate 26, the second side plate 27 and the upper plate 21.

[0094] In one embodiment, the sealing structure 28 is a low-temperature resistant soft rubber and plastic product, and its flexibility and sealing performance do not change in an environment of -30°C.

[0095] See Figure 9 In one embodiment, the foldable rigid cold storage compartment sealing structure 2 also includes multiple cold storage ice crystal boxes 3.

[0096] Multiple cold storage ice crystal boxes 3 are installed on the inner side of the upper plate 21, the first side plate 26, and the second side plate 27. The cold storage ice crystal boxes 3 are made of food-grade thickened PE with a freezing point of -20℃. They have short freezing time, high cold storage capacity, and can be reused without water injection. There is no limit to the number of uses if the packaging is not damaged. When the ice crystals in the cold storage ice crystal box 3 freeze and melt, the cold energy released is much greater than that of water, which directly plays a role in rapid cooling. Under full load conditions, it can maintain a temperature of ≤10℃ inside the box for 24 hours after power failure (ambient temperature 46℃, initial temperature -10℃), which can meet the cold storage and insulation needs under tight power supply conditions in the field.

[0097] For example, there are 16 ice storage boxes 3, of which 4 are arranged on the inner side of the upper plate 21, 3 on each of the two first side plates 26, and 3 on each of the two second side plates 27.

[0098] In one embodiment, the foldable rigid refrigerator compartment sealing structure 2 is also provided with an LED light 5 for nighttime illumination.

[0099] In one embodiment, a pallet 4 is provided inside the foldable rigid refrigerator compartment sealing structure 2, and a turnover basket is provided on the pallet 4 for the classified storage and retrieval of food.

[0100] In one embodiment, the foldable rigid refrigerator compartment sealing structure 2 also includes a gap detection system. The gap detection system is located on the inner side of the first back plate 24 near the second back plate 25 and is used to detect the gaps in the sealing structure door 23. When the sealing structure door 23 is not closed tightly, an alarm is issued to the user so as to ensure that the sealing structure door 23 is always kept closed when the user is not using it, to prevent cold loss and leakage, and to enable the foldable rigid refrigerator compartment sealing structure 2 to achieve a better heat preservation effect.

[0101] The gap detection system includes a miniature camera and a gap detection unit.

[0102] The miniature camera is connected to the gap detection unit and is positioned directly in front of the sealed structure door 23 so as to capture complete image information of the sealed structure door 23 and periodically send the captured image information of the sealed structure door 23 to the gap detection unit.

[0103] After receiving the image information, the gap detection unit analyzes and processes the image to obtain the gap detection value. When the gap detection value is greater than the preset door gap value, it indicates that the sealing structure door 23 is not closed tightly. At this time, an alarm is issued to the user so that the user can close the sealing structure door 23 tightly in time.

[0104] See Figure 10In one embodiment, after receiving image information, the gap detection unit analyzes and processes the image to obtain a gap detection value. When the gap detection value is greater than a preset door gap value, it indicates that the sealing structure door 23 is not closed tightly. At this time, an alarm is issued to the user so that the user can close the sealing structure door 23 tightly in time. The gap detection unit obtains the value through the following sealing detection method of the foldable rigid refrigerator compartment sealing structure 2:

[0105] S1, acquire image information of the sealed structure door 23.

[0106] S2 analyzes and processes the image information to obtain the gap detection value.

[0107] S3, determine whether the gap detection value is greater than the preset door gap value, and obtain the first judgment result.

[0108] When the first judgment result is yes, an alarm message indicating that the door gap is not closed properly is issued, and after waiting for time P, the process returns to execute S1.

[0109] If the first judgment result is negative, wait for time P and then return to execute S1.

[0110] It should be noted that the preset door gap value and time P mentioned above can be set by the user or obtained from historical data. This invention does not impose any specific limitations.

[0111] In one embodiment, the image information is analyzed and processed to obtain a gap detection value, including:

[0112] S21, using the first gap calculation model, the image information is processed to obtain the first image information;

[0113] The calculation model for the first gap is as follows:

[0114] E i =ε1·U i +ε2·V i +ε3·W i +ε4 1≤i≤M;

[0115] ε1+ε2+ε3=1;

[0116] Where E represents the first image information, E i U is the value of the i-th pixel in the first image information. i V represents the red channel value of the i-th pixel in the cold image information. i W represents the green channel value of the i-th pixel in the image information. i Let ε1 be the blue channel value of the i-th pixel in the image information, M be the total number of pixels in the image information, and ε1, ε2, ε3 and ε4 be the first weight parameter, the second weight parameter, the third weight parameter and the fourth weight parameter, respectively.

[0118] S22, preprocess the first image information to obtain the second image information; the second image information includes left edge contour information and right edge contour information.

[0119] It should be noted that the preprocessing of the first image information to obtain the second image information involves using Gaussian blur algorithm, Canny edge detection algorithm, morphological processing algorithm, and contour detection algorithm to calculate and process the first image information. The second image information includes left edge contour information and right edge contour information, both of which include L contour coordinate values.

[0120] It should be noted that both the left and right edge contour information include L contour coordinate values, including x-coordinate values ​​and corresponding y-coordinate values. The x-coordinate values ​​in the left and right edge contour information are one-to-one and equal. For example, if the left edge contour information is {[1,2],[2,2],[3,1].[4,2],[5,3]}, then the right edge contour information is {[1,1],[2,2],[3,2].[4,3],[5,2]}, where the x-coordinate values ​​in the left and right edge contour information are the same, both being 1,2,3,4,5.

[0121] For example, morphological processing algorithms include dilation and erosion.

[0122] S23, using the second gap calculation model, the second image information is calculated and processed to obtain the gap detection value;

[0123] The calculation model for the second gap is as follows:

[0124]

[0125] Wherein, JC is the gap detection value, ZB and YB are the left edge contour information and the right edge contour information, respectively, ZB(j) is the y coordinate value corresponding to the x coordinate value in the j-th contour coordinate information in the left edge contour information, YB(j) is the y coordinate value corresponding to the x coordinate value in the j-th contour coordinate information in the right edge contour information, ZPJ and YPJ represent the average y coordinate value corresponding to the x coordinate value in all contour coordinate information in the left edge contour information and the average y coordinate value corresponding to the x coordinate value in all contour coordinate information in the right edge contour information, respectively, and ε5, ε6 and ε7 represent the fifth weight parameter, the sixth weight parameter and the seventh weight parameter.

[0126] It should be noted that the fifth, sixth, and seventh weight parameters can be set by the user or obtained from historical data, and this embodiment of the invention does not impose any limitations.
