[0054] In order to illustrate the technical solutions described in the present application, the following will be described in detail in combination with specific drawings and examples.

[0055] Please refer to Figure 1 and Figure 2 The present application provides a household appliance 200, which comprises a device shell and a door structure 100 rotatably arranged on the device shell. The device shell is provided with an inner cavity (not shown), and the side of the device shell facing the door structure 100 is provided with a second opening 90 communicating with the inner cavity. The door structure 100 is rotatably installed on the device shell to close the second opening 90 and open the second opening 90.

[0056] According to the specific type of the household appliance 200, the function of the inner cavity can be different.

[0057] For example, the household appliance 200 can be a clothes treatment device.

[0058] Specifically, the laundry treating apparatus can be a drying machine. The household appliance further comprises a drum disposed in the inner cavity. The inner cavity is configured to accommodate the drum. The drum is internally provided with a laundry treating space, and the drum is provided with a third opening communicating with the laundry treating space of the drum. The third opening can be aligned with the second opening 90, or a portion of the drum surrounding the third opening can be located in the second opening 90, so that the third opening is located in the second opening 90. In summary, the laundry can enter the laundry treating space through the second opening 90 and the third opening.

[0059] Alternatively, the laundry treating apparatus can be a washing machine or a washing machine with a drying function. In this embodiment, an outer drum located in the inner cavity and outside the drum can also be included. The outer drum is fixedly arranged relative to the apparatus housing, and the inner drum rotates in the outer drum. The inner drum is internally provided with a laundry treating space. Of course, at this time, the outer drum is also provided with a fourth opening communicating with the second opening 90 and the third opening, which will not be described in detail.

[0060] In other embodiments, the household appliance 200 can also be an apparatus with other functions.

[0061] The apparatus housing is a three-dimensional hollow structure, for example, the apparatus housing is a substantially regular hexahedron. For ease of illustration, only a portion of the apparatus housing is shown in the drawings of the embodiments of the present application. As shown in Figure 1 and Figure 2 The portion of the apparatus housing facing the door structure 100 serves as a front panel 9, and the front panel 9 is provided with the second opening 90 described above.

[0062] It should be noted that the household appliance 200 has a specific orientation when in use. The "front" described above and the "rear", "upper", "lower", "left" and "right" used hereinafter are based on the orientation of the user when using the household appliance 200.

[0063] The door structure 100 is rotatably mounted at one side edge of the front panel 9, such as the left side edge or the right side edge.

[0064] Please refer to Figure 3 , Figure 4 and Figure 5 for a detailed description of the door structure 100 of the present application.

[0065] As shown in Figure 2 and Figure 3As shown, the door body structure 100 comprises an outer protective layer 4 and a door panel 5 arranged oppositely, and a bowl-shaped member 6. The door panel 5 is provided with a first opening 519, and one end of the bowl-shaped member 6 is arranged in the first opening 519 and the other end is arranged on the side of the door panel 5 away from the outer protective layer 4. Specifically, the outer protective layer 4 is arranged on the front side of the door panel 5, and the bowl-shaped member 6 protrudes backward from the first opening 519 of the door panel 5. When the door body structure 100 rotates relative to the front panel 9, the bowl-shaped member 6 can enter at least part of the second opening 90 and close the second opening 90. The outer protective layer 4 is a transparent material layer, specifically a glass layer, to balance good transparency and strength.

[0066] The front surface of the door panel 5 and the rear surface of the outer protective layer 4 are bonded together by gluing. As shown in Figure 4 and Figure 6 The side surface of the door panel 5 facing the outer protective layer 4 is provided with a glue groove 510, which is arranged around the outer edge of the door panel 5. The glue groove 510 is filled with adhesive to bond the outer protective layer 4 and the door panel 5 to each other.

[0067] As shown in Figure 4 and Figure 6 In the up-down direction, the first opening 519 on the door panel 5 is not centrally arranged, and generally, the first opening 519 is located at a relatively upper position. Therefore, the part of the door panel 5 below the first opening 519 has a larger area.

[0068] In one embodiment, the area ratio of the door body structure 100 to the front panel 9 is greater than or equal to 0.8, and the area ratio of the door panel 5 to the front panel 9 is greater than or equal to 0.8. That is, the door body structure 100 can cover an area of 80% or more of the front panel 9. On the door body structure 100, in addition to being able to close the second opening 90 by the bowl-shaped member 6, the door panel 5 also has a larger area for carrying the bowl-shaped member 6. Therefore, the larger area of the door panel 5 also provides stable support for the bowl-shaped member 6.

[0069] In some optional embodiments, the area ratio of the door body structure 100 to the front panel 9 is greater than or equal to 0.9, and the area ratio of the door panel 5 to the front panel 9 is greater than or equal to 0.9.

[0070] In order to ensure the bonding strength between the door panel 5 and the outer protective layer 4, and in particular to ensure the bonding strength between the part of the door panel 5 below the first opening 519 and the outer protective layer 4, as shown in Figure 4 , Figure 5 , Figure 6 and Figure 7 The glue groove 510 comprises a reinforcing glue groove 511 below the first opening 519. The projection length T of the reinforcing glue groove 511 on the vertical surface of the corresponding outer edge of the door panel 5 is greater than the line width D.

[0071] Compared with the part of the glue groove 510 except the reinforcing glue groove 511, the reinforcing glue groove 511 can provide stronger bonding force, thereby ensuring that the part of the door panel 5 and the outer protective layer 4 below the first opening 519 can be stably bonded together.

[0072] Specifically, as shown in Figure 4 and Figure 6 , the door panel 5 is a substantially regular quadrilateral, which can even be a rectangle. The door panel 5 has four edges close to straight lines or straight lines, which are defined as an upper edge 513, a lower edge 514, a left edge 515 and a right edge 516, respectively. The glue groove 510 is arranged along the four edges of the door panel 5, and thus different parts of the glue groove 510 extend along the up-down direction and the left-right direction, respectively.

[0073] In the embodiment of the present application, the projection length T of the reinforcing glue groove 511 on the vertical plane of the outer edge of the door panel 5 is greater than the line width D of the reinforcing glue groove 511. First, as shown in Figure 5 and Figure 7 , the line width D of the glue groove 510 and the reinforcing glue groove 511 refers to the line width of the orthographic projection pattern of the glue groove 510 and the reinforcing glue groove 511 on the plane where the door body structure is located, and also refers to the width of the path traveled by the glue gun when injecting glue into the glue groove 510. The line width direction of the glue groove 510 and the reinforcing glue groove 511 (see Figure 5 and Figure 7 ) is perpendicular to the movement path of the glue gun, or in other words, the line width direction of the glue groove 510 and the reinforcing glue groove 511 is the perpendicular direction of the movement path of the glue gun. It can be understood that the line width direction can be different for different positions of the glue groove 510 and the reinforcing glue groove 511.

[0074] Specifically, as shown in Figure 4 and Figure 5 , in one embodiment, the reinforcing glue groove 511 includes at least two sub-glue grooves 5111 parallel to the outer edge of the door panel 5, and the two ends of the sub-glue groove 5111 are connected to each other. Specifically, each sub-glue groove 5111 is arranged along part of the left edge 515, the lower edge 514 and part of the right edge 516 of the door panel 5, and the two sub-glue grooves 5111 are arranged at intervals in the direction from the edge of the door panel 5 to the first opening 519.

[0075] As Figure 5As shown, for the reinforcing glue groove 511, when glue is applied by using a glue gun, each sub-glue groove 5111 is applied independently, that is, the glue gun passes through two sub-glue grooves 5111 in sequence, rather than passing through two sub-glue grooves 5111 at the same time. The line width D of the sub-glue groove 5111 is also the line width D of the reinforcing glue groove 511, and the line width direction is perpendicular to the edge of the door panel 5. Specifically, for the sub-glue groove 5111 arranged along the left edge 515 and the right edge 516 of the door panel 5, the line width direction is the left-right direction, and for the sub-glue groove 5111 arranged along the lower edge 514 of the door panel 5, the line width direction is the up-down direction. The projection length T of the reinforcing glue groove 511 on the vertical plane of the corresponding outer edge of the door panel 5 means that a vertical plane perpendicular to the outer edge of the door panel 5 is defined by the outer edge of the door panel 5 corresponding to the reinforcing glue groove 511, and the projection length of the reinforcing glue groove 511 on the vertical plane in the direction of the outer edge of the corresponding door panel 5. For example, Figure 5 As shown, for the two sub-glue grooves 5111 arranged along the lower edge 514 of the door panel 5, the projection length of the two sub-glue grooves 5111 on the plane perpendicular to the lower edge 514 is the sum of the line widths D of the two sub-glue grooves 5111.

[0076] As shown, Figure 4 As shown, the degree of the two end points of the reinforcing glue groove 511 in the orthographic projection pattern of the glue groove 510 on the plane of the door body structure 100 is greater than or equal to 3. Here, the "degree of the end point" refers to the number of edges associated with the end point in a plane pattern. Accordingly, if the degree of an end point is odd, the end point can also be referred to as a "singular point".

[0077] In the embodiment, the degree of the two end points of the reinforcing glue groove 511 in the orthographic projection pattern of the glue groove 510 on the plane of the door body structure 100 is greater than or equal to 3. Therefore, the reinforcing glue groove 511 includes at least two sub-glue grooves 5111, and the two ends of the sub-glue grooves 5111 are connected to each other and connected to the two ends of other parts of the glue groove 510.

[0078] In a specific embodiment, as shown in Figure 4 and Figure 5 The reinforcing glue groove 511 includes two sub-glue grooves 5111, and the two ends of the sub-glue grooves 5111 are connected to each other and connected to the two ends of other parts of the glue groove 510. Figure 4 As shown, the other part of the glue groove 510 and the left end of the reinforcing glue groove 511 form a connection point, and the degree of the connection point is 3; the other part of the glue groove 510 and the right end of the reinforcing glue groove 511 form a connection point, and the degree of the connection point is 3.

[0079] In other optional embodiments, the reinforcing glue groove 511 comprises at least three sub-glue grooves 5111, and the two ends of the sub-glue grooves 5111 are connected with each other and connected with the two ends of the other part of the glue groove 510. When the reinforcing glue groove 511 comprises three sub-glue grooves 5111, the other part of the glue groove 510 and the left end of the reinforcing glue groove 511 form a connection point, and the degree of the connection point is 4.

[0080] As shown in Figure 6 and Figure 7 , in one embodiment, the reinforcing glue groove 511 is wavy. Here, the wavy refers to the reinforcing glue groove 511 is in a shape of undulating bending relative to the edge of the door panel 5, as shown in Figure 6 and Figure 7 , the reinforcing glue groove 511 comprises a plurality of reinforcing groove portions 5113 connected in sequence, and the adjacent two reinforcing groove portions 5113 of the reinforcing glue groove 511 are connected in a relatively bending manner. Specifically, the adjacent two reinforcing groove portions 5113 of the reinforcing glue groove 511 are connected in a smooth transition bending manner, or the adjacent two reinforcing groove portions 5113 of the reinforcing glue groove 511 are connected in a zigzag bending manner.

[0081] Similarly, as shown in Figure 7 , the reinforcing groove portion 5113 of the reinforcing glue groove 511 is inclined relative to the edge of the door panel 5. Taking the lower edge 514 of the door panel 5 as a reference, the extending direction of the reinforcing groove portion 5113 is inclined relative to the up-down direction and the left-right direction. Therefore, the line width direction (indicated by X in Figure 7 ) of the reinforcing glue groove 511 is perpendicular to the extending direction, and the projection length T of the reinforcing glue groove 511 on the vertical plane of the corresponding outer edge of the door panel 5 is greater than the line width D of the reinforcing glue groove 511. Figure 7 , taking the lower edge 514 of the door panel 5 as a reference, the projection length T of the reinforcing glue groove 511 on the vertical plane of the corresponding outer edge of the door panel 5 is greater than the line width D of the reinforcing glue groove 511.

[0082] As shown in Figure 6 , in one embodiment, the glue groove 510 is a one-stroke figure. The glue groove 510 formed on the basis of the one-stroke figure can reduce the difficulty of glue running, facilitate glueing, ensure that the glue can be completely filled in the glue groove 510, reduce or even avoid defects such as air bubbles in the glue, and improve the bonding quality between the door panel 5 and the outer protective layer 4.

[0083] For a one-stroke figure, the number of singular points is 0 or 2. When the number of singular points is 0, the one-stroke figure is a circle. As shown in Figure 6 , in one embodiment, the glue groove 510 is a one-stroke figure and has two singular points.

[0084] As shown in Figure 6As shown, there is one wavy reinforcing groove 511, and the two ends of the other parts of the groove 510 are connected to the two ends of the reinforcing groove 511.

[0085] Furthermore, such as Figure 6 As shown, the side of the door panel 5 facing the outer protective layer 4 is also provided with a circuit board mounting groove 518. A glue groove 510 semi-encloses the circuit board mounting groove 518 to form a clearance opening 5105. Furthermore, the portion of the glue groove 510 located above the first opening 519 and on the horizontal side of the circuit board mounting groove 518 forms a first closed annular portion 5101, and the clearance opening 5105 is located on the side of the first closed annular portion 5101 near the first opening 519. The glue groove 510 also includes a second closed annular portion 5102, which avoids the circuit board mounting groove 518 and is provided along the edge of the door panel 5, and of course, also encloses the first opening 519. The first closed annular portion 5101 and the second closed annular portion 5102 are connected by a strip portion 5103. The two ends of this strip portion 5103 form singularities. The second closed annular portion 5102 includes the aforementioned reinforcing adhesive groove 511, or in other words, at least a portion of the second closed annular portion 5102 located below the first opening 519 serves as the aforementioned reinforcing adhesive groove 511.

[0086] The clearance opening 5105 separates the first closed annular portion 5101 and the second closed annular portion 5102, connecting them only through the strip portion 5103. At the same time, the first closed annular portion 5101 and the second closed annular portion 5102 form a semi-enclosed surround of the circuit board mounting groove 518 through the clearance opening 5105 between them.

[0087] In one embodiment, the line width D of the glue groove 510 is 6 mm to 12 mm (including the line width of the reinforcing glue groove 511 and the line width of other parts of the glue groove 510). This design is intended to accommodate the speed at which the glue flows from the glue gun, allowing the glue to be fully dispersed within the glue groove 510 and fill the entire glue groove 510 along the line width direction. Simultaneously, the appropriate line width D of the glue groove 510 allows the required bonding strength to be achieved with a minimal number of sub-glue grooves 5111 or the length of the wavy reinforcing glue groove 511.

[0088] In some embodiments, the reinforcement groove 511 can be provided in combination with the two forms described above. That is, the reinforcement groove 511 can include at least two sub-grooves 5111 provided parallel to the outer edge of the door panel 5, and each sub-grooves 5111 is wavy.

[0089] Please see Figure 3As shown, in one embodiment, the door plate 5 comprises a front door plate 51 and a rear door plate 52 arranged oppositely, the front door plate 51 is located between the outer protective layer 4 and the rear door plate 52; the first opening 519 penetrates through the front door plate 51 and the rear door plate 52; the periphery of the bowl-shaped part 6 is located between the front door plate 51 and the rear door plate 52. Therefore, the periphery of the bowl-shaped part 6 is clamped between the front door plate 51 and the rear door plate 52.

[0090] The front door plate 51 and the rear door plate 52 can be fixedly connected together by fasteners. For example, locked together by bolts and the like.

[0091] As mentioned before, the door plate 5 has a large area, and the front door plate 51 and the rear door plate 52 also have a large area. In one embodiment, please refer to Figure 8 , Figure 9 and Figure 10 As shown, the door plate 5 further comprises at least one reinforcing part 53, the reinforcing part 53 is fixed on the rear surface of the front door plate 51. The reinforcing part 53 is used to strengthen the strength of the front door plate 51, to avoid the deformation of the front door plate 51, and further to avoid the adhesive failure between the front door plate 51 and the outer protective layer 4 due to the deformation of the front door plate 51.

[0092] The reinforcing part 53 is made of a material with strong anti-deformation ability. For example, the reinforcing part 53 is a metal part, specifically can be a steel part, an iron part, and more specifically can be a galvanized steel part. In addition, through a suitable processing technology, the anti-deformation ability can be further improved, for example, the reinforcing part 53 can be a sheet metal part or a hot-rolled part, etc.

[0093] As shown in Figure 10 The reinforcing part 53 comprises a first reinforcing part 535 and at least one second reinforcing part 536, the first reinforcing part 535 is parallel to the front door plate 51, and the second reinforcing part 536 extends from at least one side of the width direction of the first reinforcing part 535 towards the outer protective layer 4. Therefore, the first reinforcing part 535 and the second reinforcing part 536 are bently connected, such as "L" shape bently connected or "bracket" shape bently connected. This can further improve the anti-deformation ability of the reinforcing part 53 itself.

[0094] As shown in Figure 10 The width L of the first reinforcing part 535 is greater than or equal to 15 millimeters, and the height H of the second reinforcing part 536 in the direction perpendicular to the outer protective layer 4 is greater than or equal to 5 millimeters. In other optional embodiments, the width L of the first reinforcing part 535 and the height H of the second reinforcing part 536 can have other numerical values, as long as the anti-deformation effect and the processing and manufacturing cost can be considered.

[0095] Please refer to Figure 9 In one embodiment, as shown, a plurality of ribs 517 are protrudingly arranged on the rear surface of the front door plate 51, and the ribs 517 are cross-shaped and net-shaped. In this way, the anti-deformation ability of the front door plate 51 itself can be improved.

[0096] Please refer to Figure 9 As shown, the surfaces of the reinforcing member 53 facing the front door panel 51 abut against the surfaces of the protrusions 517. Specifically, the protrusions 517 have a first abutting surface parallel to the rear door panel 52 and a second abutting surface perpendicular to the rear door panel 52 (both not shown), the first reinforcing portion 535 abuts against the first abutting surface, and the second reinforcing portion 536 abuts against the second abutting surface. The purpose of such arrangement is that the surfaces of the reinforcing member 53 facing the front door panel 51 abut against the surfaces of the protrusions 517, so that the surfaces of the reinforcing member 53 facing the front door panel 51 can be used entirely to limit the deformation of the front door panel 51.

[0097] The reinforcing member 53 is fixed on the protrusions 517 by fasteners or the like. Specifically, as shown, a fastener such as a bolt passes through the first reinforcing portion 535 and is locked with the protrusions 517. Figure 9

[0098] In order to be able to reinforce in multiple directions at multiple positions of the front door panel 51, so that the front door panel 51 does not deform obviously in any direction, in one embodiment, as shown, the number of reinforcing members 53 is multiple, and the reinforcing members 53 are distributed on different sides of the first opening 519, and even, different reinforcing members 53 can be arranged in different directions. Figure 8

[0099] As shown, in one embodiment, the reinforcing member 53 includes a first reinforcing member 531 arranged in a vertical direction, and the first reinforcing member 531 is arranged on the left side and / or the right side of the first opening 519. The first reinforcing member 531 has a certain height (dimension in the up-down direction), so that the upper end and the lower end of the front door panel 51 can be kept relatively fixed in shape. Figure 8

[0100] In one embodiment, the ratio of the height of the first reinforcing member 531 to the height (dimension in the up-down direction) of the front door panel 51 is greater than or equal to 0.6, so as to ensure that the first reinforcing member 531 can correspond to most of the area in the height direction of the front door panel 51. Optionally, in one embodiment, the ratio of the height of the first reinforcing member 531 to the height of the front door panel 51 is greater than or equal to 0.7. Optionally, in one embodiment, the ratio of the height of the first reinforcing member 531 to the height of the front door panel 51 is greater than or equal to 0.8. In more embodiments, the ratio of the height of the first reinforcing member 531 to the height of the front door panel 51 can be set according to specific needs.

[0101] In one embodiment, as shown, the reinforcing member 53 includes a second reinforcing member 532 arranged in a horizontal direction, and the second reinforcing member 532 is arranged on the left side and / or the right side of the first opening 519. The second reinforcing member 532 has a certain width (dimension in the left-right direction), so that the left end and the right end of the front door panel 51 can be kept relatively fixed in shape. Figure 8 ​​​As shown, the number of the first reinforcing members 531 is two, and they are respectively located at the left side and the right side of the first opening 519. Among the left edge 515 and the right edge 516 of the door body structure 100, one is used to set a door lock mounting portion, and the other is used to set a hinge mounting portion. That is, the first first reinforcing member 531 is close to the door lock mounting portion of the door body structure 100, and the second first reinforcing member 531 is close to the hinge mounting portion (the hinge mounting portion is used to be hinged with the front panel 9) of the door body structure 100.

[0102] Further optionally, the distance between the first first reinforcing member 531 and the door lock mounting portion is smaller, because the door lock mounting portion is farther away from the hinge mounting portion and has a greater tendency to deform, and the first first reinforcing member 531 is arranged close to the door lock mounting portion, which is more conducive to preventing the front door panel 51 from deforming at this location.

[0103] If the first opening 519 is centrally arranged in the left-right direction, the distance between the first first reinforcing member 531 and the first opening 519 is greater than the distance between the second first reinforcing member 531 and the first opening 519. In other optional embodiments, the first reinforcing member 531 can be arranged only on the left side or the right side of the first opening 519.

[0104] In one embodiment, please refer to Figure 4 , Figure 6 and Figure 8 As shown, the lowest point of the first reinforcing member 531 can be lower than the highest point of the reinforcing glue groove 511. That is, the first reinforcing member 531 can extend downward beyond the highest point of the reinforcing glue groove 511 (the reinforcing glue groove 511 and the first reinforcing member 531 are located at different surfaces of the front door panel 51, so Figure 8 in , the reinforcing glue groove 511 is shown by a dashed line). Since the reinforcing glue groove 511 is arranged along the edge of the front door panel 51, the first reinforcing member 531 is also located at a position closer to the left edge 515 and the right edge 516 of the front door panel 51, so the lower segment of the first reinforcing member 531 can be closer to the upper segment of the reinforcing glue groove 511. The first reinforcing member 531 can ensure the anti-deformation ability of the surrounding area on the front door panel 51, a part of the reinforcing glue groove 511 can be closer to the area, and the deformation tendency of the reinforcing glue groove 511 is smaller, so the adhesive strength between the front door panel 51 and the outer protective layer 4 can be further increased.

[0105] In an optional embodiment, the first reinforcing member 531 overlaps the reinforcing glue groove 511 in the thickness direction of the door body structure 100. The purpose of this arrangement is that the deformation tendency of the reinforcing glue groove 511 is smaller, so the adhesive strength between the front door panel 51 and the outer protective layer 4 can be further increased.

[0106] Please continue to refer to Figure 8As shown, in one embodiment, the reinforcing member 53 can include a second reinforcing member 532 arranged in the horizontal direction. The second reinforcing member 532 can be arranged on the upper side and / or the lower side of the first opening 519.

[0107] At this time, the ratio of the length (dimension in the left-right direction) of the second reinforcing member 532 to the width (dimension in the left-right direction) of the door panel 5 is greater than or equal to 0.6.

[0108] The second reinforcing member 532 has a certain length, and thus can ensure that the left end and the right end of the front door panel 51 can maintain a relatively fixed shape.

[0109] The ratio of the length of the second reinforcing member 532 to the width of the front door panel 51 is greater than or equal to 0.6, so as to ensure that the second reinforcing member 532 can correspond to most of the area in the left-right direction of the front door panel 51. Alternatively, in one embodiment, the ratio of the length of the second reinforcing member 532 to the width of the front door panel 51 is greater than or equal to 0.7. Alternatively, in one embodiment, the ratio of the length of the second reinforcing member 532 to the width of the front door panel 51 is greater than or equal to 0.8. In more embodiments, the ratio of the length of the second reinforcing member 532 to the width of the front door panel 51 can be set according to specific needs.

[0110] As shown in Figure 8 the reinforcing member 53 includes two second reinforcing members 532 arranged in the horizontal direction, and the two second reinforcing members 532 are arranged near the upper edge 513 and the lower edge 514 of the front door panel 51, respectively. In other alternative embodiments, the second reinforcing member 532 can be arranged only near the upper edge 513 and near the lower edge 514 of the front door panel 51.

[0111] In one embodiment, please refer to Figure 4 , Figure 6 and Figure 8 , the second reinforcing member 532 and the glue groove 510 partially overlap in the thickness direction of the door body structure 100. For example, the second reinforcing member 532 arranged near the lower edge 514 of the front door panel 51 overlaps with the reinforcing glue groove 511, and the second reinforcing member 532 arranged near the upper edge 513 of the front door panel 51 overlaps with other parts of the glue groove 510. The purpose of such arrangement is that the second reinforcing member 532 can ensure the anti-deformation ability of the area around it on the front door panel 51, a part of the glue groove 510 can be relatively close to this area, and the glue groove 510 has a smaller tendency to deform, thus the adhesive strength between the front door panel 51 and the outer protective layer 4 can be further increased.

[0112] The reinforcing member 53 is arranged close to the edge of the front door panel 51, and in order to ensure the balanced anti-deformation ability of the front door panel 51, the edge of the reinforcing member 53 is recessed from the edge of the front door panel 51 by a distance greater than or equal to 15 mm in the width direction of the reinforcing member 53. The recessed distances of the reinforcing members 53 at different positions from the edge of the front door panel 51 can not be completely the same. For example, the distance between the second reinforcing member 532 at the upper side and the upper edge 513 of the front door panel 51 can be greater than or equal to 15 mm, and the distance between the second reinforcing member 532 at the lower side and the lower edge 514 of the front door panel 51 can be greater than or equal to 15 mm; the distance between the second reinforcing member 532 at the left side (e.g., close to the door lock mounting portion) and the left edge 515 of the front door panel 51 can be greater than or equal to 40 mm, and the distance between the second reinforcing member 532 at the right side (e.g., close to the hinge mounting portion) and the right edge 516 of the front door panel 51 can be greater than or equal to 50 mm, etc. These are only examples, and in actual applications, the recessed distances of the reinforcing members 53 from the corresponding edges of the front door panel 51 can have other values.

[0113] In more embodiments, the first reinforcing member 531 and the second reinforcing member 532 can be used in combination. For example, one first reinforcing member 531 and two second reinforcing members 532 are used simultaneously, or two first reinforcing members 531 and two second reinforcing members 532 are used simultaneously, etc.

[0114] Please refer to Figure 10 As shown, in one embodiment, along the length direction of the reinforcing member 53, the reinforcing member 53 at least includes the third reinforcing portion 537 and the fourth reinforcing portion 538 connected to each other, and in the length direction of the reinforcing member 53, the third reinforcing portion 537 and the fourth reinforcing portion 538 are misaligned with each other. That is, the third reinforcing portion 537 and the fourth reinforcing portion 538 are not connected in a straight line. The surfaces of the third reinforcing portion 537 and the fourth reinforcing portion 538 away from the front door panel 51 are different in distance from the outer protective layer 4. For example, the surface of the third reinforcing portion 537 away from the front door panel 51 is relatively high, and thus an avoiding space 539 is formed at the surface of the fourth reinforcing portion 538 away from the front door panel 51 relative to the third reinforcing portion 537.

[0115] It can be understood that the third reinforcing portion 537 includes part of the first reinforcing portion 535 and part of the second reinforcing portion 536, and the fourth reinforcing portion 538 includes part of the first reinforcing portion 535 and part of the second reinforcing portion 536.

[0116] The purpose of such an arrangement is to, for example, Figure 10As shown in the figures, the surface of the fourth reinforcing portion 538 facing away from the front door panel 51 is recessed relative to the surface of the third reinforcing portion 537 facing away from the front door panel 51, and the space formed by the recessing can be used to avoid other structures, for example, to avoid wiring, etc. More specifically, for example, the rear surface of the rear door panel 52 can be recessed with a wire slot for accommodating wiring, connection terminals, etc., at this time, the front surface of the rear door panel 52 protrudes correspondingly towards the front door panel 51, and the protruding area can correspond to the above-mentioned avoiding space 539, so that there is no wiring, terminal protruding on the rear surface of the rear door panel 52.

[0117] In a specific application, different positions of the rear surface of the protruding rib 517 on the front door panel 51 can be designed with height differences to adapt to the third reinforcing portion 537 and the fourth reinforcing portion 538, so that the front surfaces of the third reinforcing portion 537 and the fourth reinforcing portion 538 can abut against the rear surface of the protruding rib 517 as much as possible.

[0118] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
