[0055] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0056] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0057] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0058] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0059] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0060] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0061] When a weighing module is set on the door body, the base of the weighing module is installed on the door body, and the weight of the storage structure and the items inside it act on the base through the weighing sensor. The side of the base facing away from the door body is easily deformed due to gravity, resulting in poor load-bearing reliability of the base and easy cracks and other damage.

[0062] In view of this, in the embodiment of the present application, the bottom plate of the base is tilted upward, so as to reserve a deformation angle for the bottom plate to deform downward under gravity, thereby improving the load-bearing capacity of the base.

[0063] The base includes a bottom plate and a side panel structure arranged on the bottom plate. The side panel structure and the bottom plate together enclose an installation cavity for installing the upper shell, so that the base is a three-dimensional structure. Viewed from the side, the base is overall "L"-shaped, further improving the structural strength and load-bearing capacity of the base.

[0064] The side panel structure is higher on the side close to the door body and lower on the side away from the door body, and the two are connected in the width direction of the door body, so that the higher part of the side panel structure extends to both sides of the length direction of the base, further improving the structural embedment and load-bearing capacity of the base.

[0065] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0066] First of all, it should be noted that in the embodiment of the present application, the width direction of the door body corresponds to the X-axis direction in the accompanying drawings; the thickness direction of the door body corresponds to the Y-axis direction in the accompanying drawings; the height direction of the door body, that is, the up-down direction, corresponds to the Z-axis direction in the accompanying drawings. In addition, in the description of the embodiment of the present application, the directional word "rear" refers to the side close to the door body, and the directional word "front" refers to the side away from the door body.

[0067] Combination Figure 1 The refrigerator of the embodiment of the present application includes a box body and a door body 10, wherein the box body is formed with a storage compartment with a front opening for storing food and other items. The door body 10 is connected to the front side of the storage compartment and is used to open or close the storage compartment.

[0068] There can be one storage compartment; there can be multiple storage compartments, which can be arranged at intervals along the height direction and / or width direction of the refrigerator. Storage compartments can be divided into freezing compartments, refrigerating compartments, and temperature-changing compartments according to different storage temperatures. Shelves can be provided in the storage compartment to increase the placement of items; drawers can be provided in the storage compartment, which can be pulled out relative to the depth direction of the refrigerator to facilitate the classified storage and retrieval of items.

[0069] In some embodiments, the door body 10 is rotatably mounted on the box body to open or close the storage compartment. Exemplarily, the door body 10 is rotatably connected to the box body through a hinge assembly. When there are multiple storage compartments, one door body 10 may be provided, and multiple storage compartments share one door body 10; or, multiple door bodies 10 may be provided, and they are corresponding to different storage compartments.

[0070] In order to increase the storage space, a shelf is usually provided on the door body corresponding to the storage compartment for refrigeration, and the opening of the shelf is upward for storing items. Usually, a plurality of shelves are provided, and the plurality of shelves are arranged at intervals along the height direction of the door body 10.

[0071] The refrigerator of the embodiment of the present application further includes a weighing shelf 20, which not only has the storage function of a conventional shelf, but can also weigh the items stored therein, so that the user can conveniently obtain the weight status or remaining amount of the items stored therein.

[0072] In some embodiments, one weighing shelf 20 is provided, and the other shelves on the door body 10 are conventional shelves without weighing function.

[0073] In other embodiments, a plurality of weighing racks 20 are provided, and the plurality of weighing racks 20 are arranged at intervals along the height direction of the door body 10. Exemplarily, all the racks provided on the door body 10 are weighing racks 20.

[0074] Combination Figure 2 and Figure 3 The weighing rack 20 of the embodiment of the present application includes a base 100 , which is installed on the door body 10 to provide an installation space for the weighing device 300 .

[0075] In some embodiments, the base 100 is fixed on the door body 10, so as to fix the weighing shelf 20 on the door body 10, and the installation methods include but are not limited to clamping, hanging, screw connection, etc.

[0076] Combination Figure 1 and Figure 2 In some embodiments, two protruding door ribs are disposed on one side of the door body 10 facing the box body, and the two door ribs are disposed oppositely on both sides of the width direction of the door body 10. The base 100 is installed on the two door ribs along both sides of the width direction of the door body.

[0077] For the convenience of description, the two door ribs include a first door rib 11 and a second door rib 12, wherein the first door rib 11 is close to the hinged side of the door body 10 and the box body. A mounting portion 13 is provided on the side of the first door rib 11 facing the second door rib 12, and a mounting portion 13 is provided on the side of the second door rib 12 facing the first door rib 11. The two mounting portions 13 are respectively connected to the two sides of the length direction of the base 100 to achieve the installation of the weighing shelf 20.

[0078] In some embodiments, the base 100 is provided with hanging ears 170 on both sides along its length direction, and a mounting opening is formed on the mounting portion 13 , and the hanging ears 170 are snapped into the mounting opening to achieve the connection between the weighing shelf 20 and the door body 10 .

[0079] It should be noted that the installation method of the base 100 is the same as that of other conventional shelves. This arrangement facilitates the installation of the same installation structure on the door body 10, thereby simplifying the structure of the door body 10; and it is convenient for adjusting the position of the weighing shelf 20 in the height direction of the door body 10 according to actual needs.

[0080] In some embodiments, the first door rib 11 and the second door rib 12 have different sizes along the door thickness direction (corresponding to the Y-axis direction in the figure), wherein the size of the second door rib 12 along the door thickness direction is greater than the size of the first door rib 11 along the door thickness direction, and the second door rib 12 protrudes from the hanging ear 170 provided on the base 100, that is, the projection of the hanging ear 170 on the second door rib 12 is located on the inner side of the second door rib 12. In this way, on the switch side of the door body 10, the second door rib 12 blocks the hanging ear 170 of the base 100, which is conducive to ensuring the aesthetic appearance of the weighing rack 20.

[0081] The embodiment of the present application does not limit whether the first door rib 11 blocks the lug 170. The first door rib 11 may block the lug 170 or not. Since the first door rib 11 is close to the hinged side of the door body 10 and the box body, the lug 170 close to the first door rib 11 faces the hinged side of the door body 10 and is not easily exposed to the user, and therefore does not affect the appearance of the weighing shelf 20.

[0082] Combination Figure 3 and Figure 4 In some embodiments, the weighing shelf 20 of the embodiment of the present application includes an upper shell 200, which is located above the base 100 and is configured to form a storage cavity 201 with a top opening for storing items.

[0083] In order to ensure the consistency of multiple shelf structures and the regularity of the structure on the door body, the upper shell 200 can be consistent with the shape of other product specification shelves. For example, the upper shell 200 is roughly a rectangular shell, the length direction of the upper shell 200 is parallel to the X-axis direction, the width direction of the upper shell 200 is parallel to the Y-axis direction, and the depth direction of the upper shell 200 is parallel to the Z-axis direction.

[0084] In some embodiments, the weighing shelf 20 includes a weighing device 300 , which is installed between the upper shell 200 and the base 100 and is configured to weigh items in the storage cavity 201 .

[0085] In some embodiments, the base 100 is formed with an installation cavity 101 to provide space for the installation of the weighing device 300, and at least part of the upper shell 200 is located in the installation cavity 101, so that the base 100 and the upper shell 200 form a concave-convex fitting embedded structure, which improves the limiting effect of the base 100 on the upper shell 200. When the upper shell 200 fails to weigh, the base 100 can still stably support the upper shell 200 to ensure the reliability of the load-bearing items; moreover, such a setting makes the upper shell 200 and the base 100 form a visual effect of an integrated appearance, which improves the aesthetics of the shelf arrangement on the door body.

[0086] Exemplarily, the weighing device 300 is fixed on the upper shell 200, and the weighing end of the weighing device 300 contacts the base 100. Alternatively, the weighing device 300 is fixed on the base 100, and the weighing end of the weighing device 300 contacts the upper shell 200.

[0087] Continue to refer to Figure 4 In some embodiments, a baffle 400 is provided between the base 100 and the upper shell 200, and an opening 401 is provided on the baffle 400 so that the weighing device 300 can be connected to the upper shell 200. Of course, the baffle 400 is also provided with an opening at the connection position between the base 100 and the upper shell 200, so that the base 100 can be connected to the upper shell 200.

[0088] The fixing method of the baffle 400 includes but is not limited to clamping, bonding, etc. The baffle 400 and the weighing device 300 are fixed on the same side. It can be understood that when the weighing device 300 is fixed to the upper shell 200, the baffle 400 is fixed to the upper shell 200; when the weighing device 300 is fixed to the base 100, the baffle 400 is fixed to the base 100. In this way, when the upper shell 200 is disassembled for cleaning, the baffle 400 can cover part of the weighing device 300, thereby playing the role of covering and protecting the weighing device 300.

[0089] It should be noted that the upper shell 200 can be removed separately for cleaning or other maintenance; or the weighing device 300 can be removed as a whole from the door body 10 for cleaning or other maintenance. The weighing device 300 can be electrically connected to the power supply device and the control device in the door body through a detachable connection terminal, so that the weighing device 300 can be detachable. When the upper shell 200 is removed separately and the weighing device 300 is fixed on the base 100, the weighing device 300 is fixed on the base 100 and does not move, and the weighing device 300 can be electrically connected to the power supply device and the control device through a cable.

[0090] Continue to refer to Figure 4 In some embodiments, the weighing device 300 includes a weighing sensor 310 for weighing items in the storage cavity 201 .

[0091] There may be one or more weighing sensors 310. In some examples, there are four weighing sensors 310, and the four weighing sensors 310 are respectively arranged at four corners of the base 100 for weighing.

[0092] The weighing sensor 310 can be fixed on the base 100, and the weighing end of the weighing sensor 310 is in contact with the upper shell 200; the weighing sensor 310 can be fixed on the upper shell 200, and the weighing end of the weighing sensor 310 is in contact with the base 100. The fixing method of the weighing sensor 310 includes but is not limited to clamping, screw connection, bonding, etc.

[0093] In some embodiments, the weighing device 300 further includes a control board 320, which is electrically connected to the weighing sensor 310 to determine the weight of the items in the storage cavity 201. The control board 320 can be disposed in the middle of the base 100 to facilitate simultaneous connection with multiple weighing sensors 310.

[0094] The control board 320 is also electrically connected to the controller in the refrigerator so that the weight of the item detected by the weighing sensor 310 is displayed on the display panel of the refrigerator, or sent to the user's terminal device.

[0095] In order to ensure the accuracy of weighing, there is a gap between the upper shell 200 and the base 100. In the weighing state, the base 100 does not support the upper shell 200, so that the weight of the upper shell 200 and the items inside it act on the weighing device 300, thereby achieving accurate weighing.

[0096] It is understandable that there is a gap between the upper shell 200 and the base 100 along the height direction of the door body. When the upper shell 200 and the base 100 have a relative position along the width direction of the door body, there is also a gap between the upper shell 200 and the base 100 along the width direction of the door body. When the upper shell 200 and the base 100 have a relative position along the thickness direction of the door body, there is also a gap between the upper shell 200 and the base 100 along the thickness direction of the door body.

[0097] In some embodiments, the base 100 is L-shaped in a side view, which helps to improve the structural strength and load-bearing capacity of the base 100.

[0098] Combination Figure 5 In some embodiments, the base 100 includes a first bottom plate 110 and a side panel structure 102 , and the side panel structure 102 is arranged around the edge of the first bottom plate 110 to form a mounting cavity 101 opening upward.

[0099] like Figure 6As shown, the first bottom plate 110 is tilted upward relative to the horizontal plane, wherein the horizontal plane is parallel to the XY plane. This causes the vertical line of the first bottom plate 110 to tilt backward; under the action of the gravity of the upper shell 200 and the items inside it, the first bottom plate 110 has a deformation space located above the horizontal plane, with better load-bearing performance, ensuring the load-bearing stability of the base 100. If the first bottom plate 110 is parallel to the horizontal plane or the first bottom plate 110 is tilted downward, when the first bottom plate 110 is subjected to gravity, it will further tilt downward, and the vertical line of the first bottom plate 110 will tilt outward, causing the corner connection of the base 100 to be easily broken, thereby causing damage to the base 100.

[0100] In some embodiments, a first angle α is formed between the first bottom plate 110 and the horizontal plane, the first angle α is greater than 0°, the first angle α is less than or equal to 3°, for example, the first angle α is 1°, 1.5°, 2°, 2.5°, 3°, etc.

[0101] In some embodiments, the rear wall surface of the side panel structure 102 close to the door body is a vertical surface, the angle between the first bottom plate 110 and the rear wall surface is complementary to the first angle α, the angle between the first bottom plate 110 and the rear wall surface is greater than or equal to 87°, and the angle between the first bottom plate 110 and the rear wall surface is less than 90°. In this way, the force of the first bottom plate 110 and the force of the rear wall surface intersect on the extension line of the force direction; under the action of gravity, the directions of the forces on both sides gradually tend to be vertical. For the weighing device, a certain amount of deformation of the first bottom plate 110 makes its load-bearing performance better.

[0102] In addition, the side panel structure 102 is provided with a step structure on both sides of the first bottom plate 110 along the width direction of the door body, and the side facing the door body is higher than the side away from the door body. In this way, the side panel structure 102 has two parts, one of which has a larger height dimension and the other has a smaller height dimension, and the two parts are butted on both sides of the first bottom plate 110 along the width direction of the door body to form a step structure; in this way, the higher-sized part of the side panel structure 102 extends from the rear side of the first bottom plate 110 to both sides of its length direction, and the area of ​​the side panel structure 102 is increased without affecting the appearance of the weighing shelf, which is conducive to improving the structural strength of the base 100; and in this way, the corner of the L-shaped base 100 moves upward from the first bottom plate 110 to the side panel structure 102, thereby improving the load-bearing capacity of the first bottom plate 110.

[0103] In some embodiments, the base 100 includes a first bottom plate 110, a first enclosure portion 120, and a second enclosure portion 130. The first enclosure portion 120 and the second enclosure portion 130 are both disposed on the first bottom plate 110, and the first enclosure portion 120 is close to the door body; the first enclosure portion 120 and the second enclosure portion 130 are connected to form a side enclosure structure 102. The connection position of the first enclosure portion 120 and the second enclosure portion 130 is located on both sides of the first bottom plate 110 along the width direction of the door body, and the height of the first enclosure portion 120 is greater than the height of the second enclosure portion 130, so that the side enclosure structure 102 forms a step structure on both sides of the length direction of the first bottom plate 110; the first bottom plate 110, the first enclosure portion 120, and the second enclosure portion 130 enclose to form the installation cavity 101.

[0104] In this way, the first enclosure portion 120 and the second enclosure portion 130 have different heights, and the first enclosure portion 120 with a larger height and the second enclosure portion 130 with a smaller height are butted on both sides of the length direction of the first base plate 110 to form a stepped side enclosure structure 102, which is beneficial to improving the structural strength of the base 100 and further improving the load-bearing capacity of the base 100.

[0105] Continue to refer to Figure 5 and Figure 6 In some embodiments, the first enclosure portion 120 includes a rear wall portion 121 and two first side wall portions 122. The two first side wall portions 122 are located at both ends of the rear wall portion 121 along the width direction of the door body and are located on the side of the rear wall portion 121 away from the door body.

[0106] The second enclosure portion 130 includes a front wall portion 131 and two second side wall portions 132. The front wall portion 131 is opposite to the rear wall portion 121 along the thickness direction of the door body; the two second side wall portions 132 are located at both ends of the front wall portion 131 along the width of the door body and are located on the side of the front wall portion 131 facing the door body.

[0107] Since the first enclosing plate portion 120 is higher than the second enclosing plate portion 130 , the second side wall portion 132 is higher than the first side wall portion 122 , and the two second side wall portions 132 are respectively connected to the two first side wall portions 122 .

[0108] Exemplarily, the base 100 is an integrally formed one-piece, which helps to ensure the stability of the connection between the various components and improve the structural strength of the base 100.

[0109] Such an arrangement encloses and forms a side panel structure 102 with a step structure, which is beneficial to improving the structural strength of the base 100 and further improving the load-bearing capacity of the base 100 .

[0110] In some embodiments, the two first side wall portions 122 are mounted on two door ribs. A hanging ear 170 is formed on one side of the two first side wall portions 122 facing away from each other to achieve connection with the mounting portion 13.

[0111] Combine again Figure 2 The first side wall portion 122 facing away from the hinged side of the door body is located on the inner side of the door rib along the thickness direction of the door body, so that the first side wall portion 122 close to the second door rib 12 is shorter than the second door rib 12 in the thickness direction of the door body, so that the first side wall portion 122 is hidden on the inner side of the second door rib 12.

[0112] In this way, by setting the first side wall portion 122, the larger height of the enclosure portion extends to the wide side of the first bottom plate 110, which is beneficial to improving the structural strength of the base 100. The first side wall portion 122 provides an installation position for the hanging ear 170, so that both sides of the weighing shelf in the length direction are connected to the door body, and the connection stability is better.

[0113] In some embodiments, Figure 5 and Figure 6 As shown, parts of the two first side wall portions 122 are recessed toward the mounting cavity 101 to form a recessed portion 1222; a protruding portion is formed on the inner side of the mounting cavity 101 at a position corresponding to the recessed portion 1222, and a recessed structure is formed at a position of the upper shell 200 corresponding to the protruding portion to match the protruding portion.

[0114] The recessed portion 1222 is provided with a hanging ear 170 connected to the door rib, so that the hanging ear 170 is recessed relative to the first side wall portion 122, so that there is a smaller gap between the first side wall portion 122 and the door rib. Such a configuration can not only hide the connection between the hanging ear 170 and the mounting portion 13, but also make the connection between the weighing shelf 20 and the door body 10 compact.

[0115] In some embodiments, the first side wall portion 122 and the second side wall portion 132 are connected by an arc-shaped connecting portion 140, and the arc-shaped connecting portion 140 is tangentially connected to the first side wall portion 122 and the second side wall portion 132. In this way, the first side wall portion 122 and the second side wall portion 132 are connected in an arc transition, which is conducive to improving the stability of the connection between the first side wall portion 122 and the second side wall portion 132, and avoiding stress concentration between the first side wall portion 122 and the second side wall portion 132, which is easy to crack and damage.

[0116] In some embodiments, the radius of the arc-shaped connecting portion 140 is greater than or equal to 2 mm, for example, the radius of the arc-shaped connecting portion 140 is 3 mm, 4 mm, 5 mm, etc. In this way, by providing the arc-shaped connecting portion 140 with a larger radius, the reliability of the connection between the first side wall portion 122 and the second side wall portion 132 is improved, and the base 100 is prevented from cracking due to gravity.

[0117] In some embodiments, the radius of the arc-shaped connecting portion 140 is greater than or equal to 5 mm, for example, the radius of the arc-shaped connecting portion 140 is 6 mm, 7 mm, etc. This configuration can improve the load-bearing capacity of the base 100 while ensuring that the arc-shaped connecting portion 140 does not crack.

[0118] In some embodiments, the wall thickness of the arc-shaped connecting portion 140 is greater than or equal to 4 mm, for example, the wall thickness of the arc-shaped connecting portion 140 is 5 mm, 6 mm, etc. This configuration further improves the structural strength of the arc-shaped connecting portion 140 and prevents the base 100 from bearing too much weight and causing cracks between the first side wall portion 122 and the second side wall portion 132.

[0119] In some embodiments, the wall thickness of the arc-shaped connecting portion 140 is greater than the wall thickness of other positions of the side panel structure 102. Such a setting is conducive to improving the structural strength of the arc-shaped connecting portion 140, and can also avoid setting too large wall thickness at other positions of the side panel structure 102 to affect the storage space.

[0120] In some embodiments, in combination Figure 7 The second side wall portion 132 has a first end and a second end relative to each other along the thickness direction of the door body, the first end of the second side wall portion 132 is connected to the arc-shaped connecting portion 140, and the second end of the second side wall portion 132 is connected to the front wall portion 131; the wall thickness of the first end of the second side wall portion 132 is the same as the wall thickness of the arc-shaped connecting portion 140, the wall thickness of the second end of the second side wall portion 132 is the same as the wall thickness of the front wall portion 131, the wall thickness of the arc-shaped connecting portion 140 is greater than the wall thickness of the front wall portion 131, and the wall thickness of at least part of the second side wall portion 132 gradually decreases from its first end to its second end.

[0121] Exemplarily, the wall thickness of the second side wall portion 132 gradually decreases from its first end to its second end; or, the wall thickness of the second side wall portion 132 close to the arc-shaped connecting portion 140 is equal to that of the arc-shaped connecting portion 140, and then the wall thickness gradually decreases from back to front; the wall thickness of the second side wall portion 132 close to the front wall portion 131 can be equal to that of the front wall portion 131, and the wall thickness of other portions gradually decreases from back to front.

[0122] Such arrangement enables the wall thickness of the end where the second side wall portion 132 is connected to the arc-shaped connecting portion 140 to gradually decrease forward, making the connection between the second side wall portion 132 and the arc-shaped connecting portion 140 more stable, avoiding the stress concentration problem caused by the sudden change in wall thickness, and helping to further improve the structural strength of the base 100.

[0123] In some embodiments, in combination Figure 8The portion of the first side wall portion 122 between the recessed portion 1222 and the second side wall portion 132 is a connecting wall portion 1221. The bottom end of the connecting wall portion 1221 is connected to the arc-shaped connecting portion 140, and the thickness of the connecting wall portion 1221 is the same as the wall thickness of the arc-shaped connecting portion 140. The wall thickness of the top end of the connecting wall portion 1221 is the same as the wall thickness of the first side wall portion 122; the wall thickness of at least part of the connecting wall portion 1221 gradually decreases from bottom to top.

[0124] Exemplarily, the wall thickness of the connecting wall portion 1221 gradually decreases from bottom to top. Alternatively, the wall thickness of the lower portion of the connecting wall portion 1221 is the same as the wall thickness of the arc-shaped connecting portion 140, and then its wall thickness gradually decreases from bottom to top; or, the wall thickness of the top portion of the connecting wall portion 1221 is the same as the thickness of the first side wall portion 122, and the wall thickness of other portions gradually decreases from bottom to top.

[0125] Such a configuration enables the connecting wall portion 1221 to have a larger wall thickness at the bottom, which helps to improve the stability of the connection between the first side wall portion 122 and the second side wall portion 132 , and further helps to improve the structural strength of the base 100 .

[0126] Combination Figure 5 and Figure 6 In some embodiments, the top end of the first side wall portion 122 facing away from the rear wall portion 121 is inclined toward the rear wall portion 121 , that is, the first side wall portion 122 is inclined backward.

[0127] Thus, a second angle β is formed between the first side wall portion 122 and the second side wall portion 132, and the second angle β is greater than 90°. Exemplarily, the second angle β is 93°. This arrangement makes the bottom end of the first side wall portion 122 larger in the direction of the door body thickness, which is beneficial to ensure the stability of its connection, and further helps to improve the structural strength of the base 100.

[0128] Combination Figure 7 and Fig. 9 In some embodiments, the top of the rear wall portion 121 is inclined toward the door body, which is convenient for demoulding the base 100. The inclination angle θ of the rear wall portion 121 can be greater than or equal to 2°.

[0129] Combine again Fig. 9 A protrusion 190 is provided on the side of the first bottom plate 110 facing the door body. When the base 100 bears weight, the protrusion 190 can abut against the inner side of the door body, provide support for the base 100, and improve the load-bearing performance of the base 100.

[0130] like Figure 5 and Figure 7As shown, in some embodiments, a first reinforcement structure 111 is disposed on the first bottom plate 110 to improve the load-bearing performance of the first bottom plate 110. The first reinforcement structure 111 may include a plurality of reinforcement ribs, and the plurality of reinforcement ribs may be arranged to form a grid structure.

[0131] Combination Figure 7 and Fig. 9 In some embodiments, a contact stage 150 is disposed on the first bottom plate 110, and the top surface of the contact stage 150 is parallel to the horizontal plane, so that an angle is formed between the top surface of the contact stage 150 and the first bottom plate 110, and the angle is equal to the first angle α.

[0132] Combination Fig.10 and Fig.11 In some embodiments, the weighing device 300 is fixed to the bottom surface of the upper shell 200, and the weighing end of the weighing sensor 310 of the weighing device 300 contacts the top surface of the contact platform 150. In this way, the contact platform 150 can not only make the weighing sensor 310 avoid the first reinforcement structure 111, but also make the weighing end of the weighing sensor 310 parallel to and in contact with the contact platform 150, thereby ensuring that the weighing sensor 310 is always in contact with the contact platform 150 during the deformation process, thereby ensuring the accuracy of weighing.

[0133] In some embodiments, part of the base 100 is located on the bottom surface of the upper shell 200 , and part of the base 100 is located on the side surface of the upper shell 200 , so as to facilitate the assembly of the base 100 and the upper shell 200 .

[0134] Combination Figure 4 and Fig.12 In some embodiments, the upper shell 200 includes a second bottom plate 210 and a circumferential enclosure plate 220 disposed on the second bottom plate 210, and the circumferential enclosure plate 220 and the second bottom plate 210 enclose a storage cavity 201 with an open top. Optionally, the upper shell 200 is an integrally formed one-piece, which is conducive to improving the structural strength of the upper shell 200.

[0135] Combination Fig.11 The first enclosure portion 120 is opposite to a portion of the circumferential enclosure portion 220, and there is a gap between the second enclosure portion 130 and the circumferential enclosure portion 220 to avoid support between the first enclosure portion 120 and the circumferential enclosure portion 220, which affects the accuracy of weighing.

[0136] The portion of the circumferential panel 220 opposite to the rear wall portion 121 is parallel to the rear wall portion 121 and has a gap, so that the portion of the circumferential panel 220 opposite to the rear wall portion 121 is inclined to facilitate demoulding of the upper shell 200.

[0137] like Fig.12As shown, the circumferential enclosure 220 includes a first portion 221 and a second portion 222, wherein the first portion 221 is located on the side of the second portion 222 facing the door body. The first portion 221 is opposite to the first enclosure portion 120 of the base 100, and the first portion 221 is recessed relative to the second portion 222 toward the storage cavity 201.

[0138] In some embodiments, the first portion 221 includes a rear side plate portion 2211 and side panel portions 2212 disposed on both sides of the rear side plate portion 2211, wherein the rear side plate portion 2211 is opposite to the rear wall portion 121 of the first enclosure portion 120 with a gap therebetween, and the rear side plate portion 2211 is parallel to the rear wall portion 121. The side panel portion 2212 avoids the recessed portion 1222 of the first side wall portion 122.

[0139] In some embodiments, the second enclosure portion 130 of the base 100 is located on the bottom surface of the second bottom plate 210 and has a gap between the bottom surfaces of the second bottom plate 210 to avoid generating support and affecting the accuracy of weighing.

[0140] The upper shell 200 and the base 100 of the embodiment of the present application are embedded in a concave and convex manner, which is convenient for positioning and assembly.

[0141] Continue to refer to Fig.12 In some embodiments, a side edge 230 is provided on the bottom edge of the second bottom plate 210 , which not only helps to improve the structural strength of the second bottom plate 210 , but also reserves space for the installation of the weighing device 300 .

[0142] The second enclosure portion 130 is located on the bottom surface of the second bottom plate 210 and outside the side enclosure edge 230 , which not only facilitates the embedding of the upper shell 200 and the base 100 , but also serves to shield the internal structure.

[0143] In some embodiments, a second reinforcement structure 250 is disposed on the bottom surface of the second bottom plate 210 to improve the structural strength of the upper shell 200. The second reinforcement structure 250 may be a mesh reinforcement rib.

[0144] Combination Figure 5 and Fig.12 In some embodiments, a buckle 160 is provided on the base 100, and a hook 240 is provided on the bottom surface of the second bottom plate 210. The hook 240 is provided with an opening, and the buckle 160 is hung in the opening. The position of the base 100 and the upper shell 200 along the height direction is limited by the buckle 160 and the hook 240.

[0145] Of course, there is a gap between the buckle 160 and the top of the opening to prevent the buckle 160 from supporting the upper shell 200 and affecting the accuracy of weighing.

[0146] In some embodiments, a plurality of buckles 160 are provided to improve the stability of the base 100 limiting the upper shell 200. Exemplarily, four buckles 160 are provided, and the four buckles 160 are respectively located at the four vertex positions of the first bottom plate 110 of the base 100, arranged in a rectangular matrix.

[0147] In some embodiments, a second limiting portion 231 is provided on the side edge 230, and a first limiting portion 180 is provided on the first bottom plate 110. The first limiting portion 180 and the second limiting portion 231 cooperate to limit the position of the upper shell 200 in the first plane, wherein the first plane is the plane where the thickness direction and the width direction of the door body are located.

[0148] Exemplarily, the second limiting portion 231 is a limiting opening provided on the side edge 230 , and the first limiting portion 180 is a limiting rib provided on the first bottom plate 110 .
