DETAILED DESCRIPTION

[0035] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0036] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the description are only some of the embodiments of the present application, not all the embodiments.

[0037] Reference Figures 1 to 15As shown, the first aspect of the present application provides a positioning structure applied to a plug, the plug comprising a plug body and a male protrusion, the positioning structure comprising a base plate 1, the base plate 1 being recessed along a first direction to form a first positioning groove 2, further comprising a second positioning groove 3, the second positioning groove 3 being recessed along the first direction from the groove bottom of the first positioning groove 2; the groove bottom of the second positioning groove 3 is provided with a plurality of insertion holes for the male protrusion, a plurality of abutting portions are formed in the second positioning groove 3, the insertion holes and the abutting portions can be combined with each other to form a plurality of positioning groups; when the groove bottom of the first positioning groove 2 or the groove bottom of the second positioning groove 3 abuts against the plug body, at least one of the plurality of positioning groups can limit the plug body.

[0038] Specifically, the plug has a plug body and a male protrusion, the male protrusion is arranged on the plug body, a power cord is connected to the plug body and electrically connected to the male protrusion, a user can hold the plug body to move the plug towards a socket, insert the male protrusion into the insertion hole of the socket, and guide the current in the socket into the electrical appliance. The standards for the plug of the power cord are different in different countries, so that different types of plugs have different shapes, and the number and distribution of the male protrusions of different types of plugs are not equal.

[0039] The above-mentioned base plate 1 is recessed along a first direction to form a first positioning groove 2, the second positioning groove 3 is on the groove bottom of the first positioning groove 2, and the second positioning groove 3 is recessed along the first direction, wherein the first direction is perpendicular to the base plate 1, and when the base plate 1 is arranged on the surface of the household electrical appliance, the first direction is towards the interior of the household electrical appliance. The groove opening of the second positioning groove 3 is exposed in the groove opening of the first positioning groove 2, and the area of the groove opening of the second positioning groove 3 is smaller than the area of the groove bottom of the first positioning groove 2, so that part of the types of plugs can abut against the groove bottom of the first positioning groove 2 after entering the first positioning groove 2.

[0040] After a plurality of types of plugs are put into the first positioning groove 2, one side of the plug provided with the male protrusion enters the first positioning groove 2 to be connected with part of the insertion holes in the plurality of insertion holes, and the edge of the plug body abuts against the abutting portion in the second positioning groove 3, so that the abutting portion and the insertion hole jointly limit the plug, or the plurality of male protrusions on the plug body are inserted into the plurality of insertion holes to limit the plug in the positioning group.

[0041] The above-mentioned abutting portion can be selected as a part of the groove wall of the second positioning groove 3, or a vertical plate or a protrusion can be arranged on the groove bottom of the second positioning groove 3, part of the male protrusions of the plug are connected with the insertion holes, and the other part of the male protrusions are connected with the abutting portion. A part of the insertion holes in the plurality of insertion holes can be selected to form a positioning group, or a part of the insertion holes in the plurality of insertion holes and a part of the abutting portions in the plurality of abutting portions can be selected to form a positioning group, a plurality of positioning groups are formed by selecting different insertion holes and different abutting portions to be combined with each other, and the male protrusions of each type of plug can correspond to one positioning group.

[0042] When the plug body enters the first positioning groove 2 and abuts against the groove bottom of the first positioning groove 2, the plug body is limited in the first direction, so that the plug body cannot continue to extend into the first positioning groove 2 along the first direction. At this time, the male protrusion of the plug body enters the second positioning groove 3 through the slot opening of the second positioning groove 3, and the male protrusion of the plug body abuts against the positioning group in the second positioning groove 3, so that the plug body is kept stable in the first positioning groove 2. When the plug body enters the first positioning groove 2 and enters the second positioning groove 3 through the slot opening of the second positioning groove 3, the plug body abuts against the groove bottom of the second positioning groove 3, so that the plug body cannot continue to extend into the second positioning groove 3 along the first direction. The plug body and the male protrusion abut against the positioning group in the second positioning groove 3, so that the plug is kept stable in the second positioning groove 3.

[0043] When the plug is inserted into the first positioning groove 2 and limited in the second positioning groove 3, the plug can be kept stable in the first positioning groove 2 and the second positioning groove 3, so as to avoid the plug from shaking in the first positioning groove 2 and the second positioning groove 3. After different types of plugs enter the first positioning groove 2, the plugs can cooperate with the positioning group in the second positioning groove 3, so that different types of plugs can be kept stable in the first positioning groove 2 and the second positioning groove 3.

[0044] The positioning structure provided in the application is used to put the first plug on the household appliance into the first positioning groove 2, and insert the first plug into the second positioning groove 3, so that one positioning group in the second positioning groove 3 limits the plug. After the second plug of different types is replaced on the household appliance, the second plug is put into the first positioning groove 2, and the second plug is inserted into the second positioning groove 3, so that the second plug cooperates with another positioning group in the second positioning groove 3, and the second plug is limited in the second positioning groove 3. When other types of plugs are used on the household appliance, the plugs can be put into the first positioning groove 2, and the plugs are inserted into the second positioning groove 3, so that the plugs cooperate with the positioning group in the second positioning groove 3.

[0045] The plug storage mechanism provided by the application is applied to a plug, the plug comprises a plug body and a male nose, the positioning structure comprises a base plate 1, the base plate 1 is recessed to form a first positioning groove 2 in a first direction, the positioning structure further comprises a second positioning groove 3, the second positioning groove 3 is recessed from the groove bottom of the first positioning groove 2 in the first direction; the groove bottom of the second positioning groove 3 is provided with a plurality of insertion holes for the male nose to be inserted, a plurality of abutting portions are formed in the second positioning groove 3, and the insertion holes and the abutting portions can be combined with each other to form a plurality of positioning groups; when the groove bottom of the first positioning groove 2 or the groove bottom of the second positioning groove 3 abuts against the plug body, at least one positioning group in the plurality of positioning groups can limit the plug body. The first positioning groove 2 and the second positioning groove 3 can accommodate a plurality of types of plugs, so as to avoid that the thickness of some types of plugs is relatively thick and protrudes from the surface of the household appliance, thereby increasing the packaging size of the household appliance; the second positioning groove 3 can limit each type of plug in the corresponding positioning group, so that different types of plugs can be kept stable in the positioning structure and avoid shaking, and the positioning structure can stably store different types of plugs and improve the efficiency during production and packaging.

[0046] Referring to Figures 1 to 5 In some embodiments, the plurality of positioning groups comprises a first positioning group, and the first positioning group comprises two first insertion holes 41 which are arranged on the groove bottom of the second positioning groove 3 at intervals. In this way, the second positioning groove 3 can be adapted to the plug with two male noses, so that the VDE plug used in Europe can be stably accommodated in the first positioning groove 2 and the second positioning groove 3.

[0047] Specifically, the first insertion holes 41 can be arranged at the middle region of the second positioning groove 3 at intervals to form the first positioning group; the first positioning group is matched with the first plug 6 in a plurality of types, and the first plug is a VDE (Verband der Elektrotechnik, Elektronik und Informationstechnike.V.) plug used in Europe. The VDE plug has two male noses which are arranged at intervals on the plug body, and the distance between the two first insertion holes 41 is equal to the distance between the two male noses of the VDE plug. When the VDE plug is placed in the first positioning groove 2, the plug body of the VDE plug enters the second positioning groove 3, so that the two male noses of the VDE plug are respectively inserted into the two first insertion holes 41 one by one, and the plug body of the VDE plug is kept stable in the second positioning groove 3 and will not shake in the direction parallel to the groove bottom of the second positioning groove 3.

[0048] Referring to Figures 1 to 5As shown in FIG. 1, in some embodiments, a boss 32 is further arranged on the inner wall of the second positioning groove 3. When a first plug 6 of a certain type is limited in the first positioning group, the end face of the boss 32 abuts against the first plug 6. In this way, the boss 32 limits the depth of the first plug 6 entering the second positioning groove 3, avoiding the length of the first plug 6 inserted into the first insertion hole 41 being too long to interfere with the parts inside the household appliance.

[0049] Specifically, the substrate 1 can be a rectangular plate, and the length direction and the width direction of the substrate 1 are parallel to the substrate 1. The boss 32 can be arranged on the side wall of the second positioning groove 3 on one side of the substrate 1 in the width direction, or the boss 32 can be arranged on the side wall of the second positioning groove 3 on one side of the substrate 1 in the length direction.

[0050] Of course, the number of bosses 32 can be two, and the two bosses 32 are arranged on the side walls of the second positioning groove 3 on opposite sides of the substrate 1 in the width direction. Or the two bosses 32 are arranged on the side walls of the second positioning groove 3 on opposite sides of the substrate 1 in the width direction.

[0051] The boss 32 lifts the groove bottom of the second positioning groove 3, so that after the first plug 6 abuts against the end face of the boss 32, a part of the male pin on the first plug 6 can be inserted into the first insertion hole 41. Since the length of the male pin of the VDE plug corresponding to the first plug 6 is relatively long, and the size of the plug body of the VDE plug is relatively small, after the VDE plug is placed in the first positioning groove 2, the VDE plug cannot abut against the groove bottom of the first positioning groove 2, and the VDE plug will enter the second positioning groove 3 as a whole. The arrangement of the boss 32 limits the depth of the VDE plug entering the second positioning groove 3, avoiding the length of the male pin inserted into the first insertion hole 41 being too long to collide and rub against the parts inside the household appliance.

[0052] Referring to Figure 1 , Figure 2 and Figures 6 to 8 As shown in FIG. 1, in some embodiments, the plurality of positioning groups includes a second positioning group, the second positioning group includes a second insertion hole 42 and two first abutting portions 51, the second insertion hole 42 is arranged on the groove bottom of the second positioning groove 3, the two first abutting portions 51 are formed on the groove wall of the second positioning groove 3, and the second insertion hole 42 and the two first abutting portions 51 are distributed in a triangular shape. In this way, the distribution of the second insertion hole 42 and the two first abutting portions 51 is adapted to the second plug 7 of the three-pin plug, and the second insertion hole 42 and the two first abutting portions 51 limit the three male pins on the second plug 7, so that the second plug 7 can be stably received in the first positioning groove 2.

[0053] Specifically, the second positioning group is adapted to the second plug 7, and the second plug can be selected as a commonly used three-flat plug in China. The three-flat plug is provided with three male pins on the plug body, and the three male pins are arranged in a triangular shape. One male pin is located at the middle of the plug body, and the other two male pins located at the two sides are arranged to be inclined to each other.

[0054] The distance between the second jack 42 and the two first abutting portions 51 is equal to the distance between the three male pins, and the distribution of the second jack 42 and the two first abutting portions 51 is consistent with the distribution of the three male pins. One male pin located between the two male pins is connected to the second jack 42, and the other two male pins are abutted to the two first abutting portions 51, respectively.

[0055] The second jack 42 is arranged at the groove bottom of the second positioning groove 3. The limiting groove 31 can be concave on the groove wall of the second positioning groove 3. The groove opening of the limiting groove 31 is arranged on the groove wall of the second positioning groove 3 and faces the second jack 42. The limiting groove 31 extends towards the groove bottom of the first positioning groove 2, so that the limiting groove 31 forms a gap on the groove bottom of the first positioning groove 2. The two side walls of the limiting groove 31 on the circumferential direction of the second jack 42 are two first abutting portions 51. The two side walls of the limiting groove 31 are inclined to each other, and the angle of the two side walls is equal to the angle of the two inclined male pins of the second plug 7.

[0056] The two male pins of the second plug 7 can enter the limiting groove 31 through the gap and abut against the opposite two side walls of the limiting groove 31. The remaining one male pin of the second plug 7 is connected to the second jack 42. The plug body of the second plug 7 abuts against the groove bottom of the first positioning groove 2, so as to limit the depth of the three male pins of the second plug 7 inserted into the second positioning groove 3, and increase the stability of the second plug 7 in the first positioning groove 2.

[0057] Of course, two protrusions can also be arranged on the groove wall of the second positioning groove 3. The two protrusions are two first abutting portions 51. The two protrusions are close to each other or face away from each other on the circumferential direction of the second jack 42, and the abutting face is formed. The two inclined male pins of the second plug 7 can abut against the two abutting faces, respectively, so that the second jack 42 and the two first abutting portions 51 can abut against the three male pins of the second plug 7.

In this way, the distribution of the third insertion hole 43 and the two second abutting portions 52 is adapted to the distribution of the three male pins of the third plug 8, so that the third insertion hole 43 and the two second abutting portions 52 limit the three male pins of the third plug 8, thereby enabling the third plug 8 to be stably accommodated in the first positioning groove 2.

[0059] Specifically, the third positioning group is adapted to the third plug 8 in a plurality of types of plugs, the third plug 8 is a BS (British Standard) plug, the BS plug has three male pins, and the three male pins are triangularly distributed. The distance between the third insertion hole 43 and the two second abutting portions 52 is equal to the distance between the three male pins, so that the distribution of the third insertion hole 43 and the two second abutting portions 52 is consistent with the distribution of the three male pins of the third plug 8.

[0060] The above-mentioned second abutting portion 52 can be selected as two partial areas on the groove wall of the second positioning groove 3, one of the three male pins located in the middle of the plug body is inserted into the third insertion hole 43, and the other two male pins are respectively abutted on the two areas on the groove wall of the second positioning groove 3, thereby enabling the second positioning group to limit the third plug 8.

[0061] The above-mentioned third plug 8 has a larger size, and compared with the second plug 7, the distance between the three male pins on the third plug 8 is larger, so that the area of the triangle formed by the three male pins of the third plug 8 is larger than the area of the triangle formed by the three male pins of the second plug 7.

[0062] In order to adapt to the size of the third plug 8, the third insertion hole 43 can be selected to be arranged on the side of the second insertion hole 42 away from the first abutting portion 51, and the two second abutting portions 52 can be selected to be arranged on both sides of the limiting groove 31 in the direction around the third insertion hole 43, that is, in the direction around the third insertion hole 43, the two first abutting portions 51 are between the two second abutting portions 52. Thus, the area of the triangle formed by the third insertion hole 43 and the two second abutting portions 52 is larger than the area formed by the second insertion hole 42 and the two first abutting portions 51.

[0063] The second jack 42 and the third jack 43 can be arranged at intervals along the length direction of the base plate 1, the second jack 42 and the first abutting portion 51 are arranged at intervals along the length direction of the base plate 1, the third jack 43 and the second abutting portion 52 are arranged at intervals along the length direction of the base plate 1, the third jack 43 is arranged on the side of the second jack 42 away from the first abutting portion 51 along the length direction of the base plate 1, and the second abutting portion 52 is arranged between the second jack 42 and the first abutting portion 51 along the length direction of the base plate 1.

[0064] Referring to Figure 1 , Figure 2 and Figures 12 to 14 In some embodiments, the plurality of positioning groups includes a fourth positioning group, the fourth positioning group includes a fourth jack and two third abutting portions 53, the fourth jack is arranged on the groove bottom of the second positioning groove 3, and the two third abutting portions 53 are arranged at intervals on the groove bottom of the second positioning groove 3, the two third abutting portions 53 have abutting walls on opposite sides, and the fourth jack and the two abutting walls form a triangular distribution. In this way, the fourth jack and the two third abutting portions 53 can be matched with the three male pins on the fourth plug 9, so that one of the three male pins on the fourth plug 9 is inserted into the fourth jack, and the other two male pins abut against the two abutting walls, so that the fourth plug 9 can be stably accommodated in the first positioning groove 2.

[0065] Specifically, the fourth positioning group corresponds to the fourth plug 9 in the plurality of types of plugs, the fourth plug 9 is a North American standard plug, and the plug body of the fourth plug 9 is provided with three male pins arranged in a triangular shape.

[0066] The fourth jack is arranged on the groove bottom of the second positioning groove 3, and the third abutting portion 53 can be a plate body structure perpendicular to the groove bottom of the second positioning groove 3.

The rectangular hole section 422 can be selected to be located on the side of the circular hole section 421 close to the first abutting portion 51 along the length direction of the base plate 1, and the circular hole section 421 and the rectangular hole section 422 are in communication with each other.

[0071] The first plug 6 is a VDE plug, both male pins of the VDE plug are cylindrical with a circular cross section, and the first jack 41 is a circular hole adapted to the male pins of the first plug 6; the second plug 7 is a three-flat plug, three male pins of the three-flat plug are cylindrical with a rectangular cross section; the third plug 8 is a BS plug, three male pins of the BS plug are cylindrical with a rectangular cross section, and the third jack 43 is a rectangular hole adapted to the male pins of the third plug 8; the fourth plug 9 is a North American power plug, one male pin of the fourth plug 9 located in the middle of the plug body is cylindrical with a circular cross section, and the other two male pins are cylindrical with a rectangular cross section.

[0072] The length of the male pin of the first plug 6 is larger than that of the male pins of the second plug 7, the third plug 8 and the fourth plug 9, so the first insertion hole 41 is a through hole; the second insertion hole 42 can be a blind hole formed by recessing the end of a column on the bottom of the second positioning groove 3, and the third insertion hole 43 can be a through hole on the bottom of the second positioning groove 3, or a blind hole formed by recessing the end face of a protrusion on the bottom of the second positioning groove 3, and the blind hole on the protrusion is the third insertion hole 43.

[0073] The circular hole section 421 is adapted to the male pin of the fourth plug 9, the male pin of the second plug 7 in the middle of the plug body can be inserted into the rectangular hole section 422, and the size of the male pin is larger, so a part of the male pin will enter the circular hole section 421, i.e. the second insertion hole 42 can be adapted to the male pin of the second plug 7, and also to the male pin of the fourth plug 9. That is, the two third abutting portions 53 are arranged on the side of the second insertion hole 42 away from the first abutting portion 51 along the length direction of the substrate 1.

[0074] Referring to Figure 1 , Figure 5 , Figure 8 , Figure 11 and Figure 14 , in some embodiments, the two abutting walls are provided with abutting ribs 531, and the two abutting ribs 531 are oppositely arranged. When a fourth plug 9 of one type is positioned in the fourth positioning group, the fourth plug 9 abuts against the two abutting ribs 531. In this way, the abutting ribs 531 can reduce the contact area between the abutting wall and the fourth plug 9, thereby reducing the friction when the fourth plug 9 slides relative to the abutting wall, and reducing the resistance when the fourth plug 9 is inserted into the second positioning groove 3.

[0075] Specifically, the protruding structures on the two abutting walls can be selected as the abutting ribs 531, and the two protruding structures are oppositely arranged along the width direction of the substrate 1 when the third abutting portion 53 is arranged on one side of the fourth insertion hole along the length direction of the substrate 1. The two male pins of the fourth plug 9 abut against the two abutting ribs 531.

[0076] Referring to Figure 1 , Figure 2 . Figure 3 , Figure 6 , Figure 9 and Figure 12As shown in some embodiments, the first positioning slot 2 includes a main slot body 21 and a wire slot 22, the wire slot 22 is arranged on one side of the main slot body 21 and connected to the main slot body 21, and the second positioning slot 3 is arranged in the main slot body 21. The main slot body 21 is used to accommodate various types of plugs, and the wire slot 22 is used to accommodate the power cord of the plug. In this way, the main slot body 21 is used to accommodate the plug, avoiding the plug protruding on the substrate 1, and the wire slot 22 can at least partially accommodate the power cord connected to the plug, avoiding the power cord protruding on the substrate 1 and increasing the packaging size of the household appliance.

[0077] Specifically, the main slot body 21 and the wire slot 22 can be arranged along the length direction of the substrate 1. The wire slot 22 is a groove recessed in the substrate 1, and the wire slot 22 is in communication with the main slot body 21. After the plug is inserted into the main slot body 21, the power cord connected to the plug is placed in the wire slot 22, so that the power cord connected to the plug does not protrude on the substrate 1. The bottom of the end of the wire slot 22 away from the main slot body 21 can be selected as an inclined surface, which is inclined toward the surface side of the substrate 1 in the direction away from the main slot body 21, so that the power cord connected to the plug is guided out of the wire slot 22 along the inclined surface.

[0078] Referring to Figure 1 , Figure 5 , Figure 8 , Figure 11 and Figure 14 As shown in some embodiments, the inner wall of the first jack 41 is provided with two oppositely arranged protrusions, the inner wall of the second jack 42 is provided with two oppositely arranged protrusions, and the inner wall of the third jack 43 is provided with two oppositely arranged positioning protrusions 431.

[0079] When the male head of the first plug 6 is inserted into the first jack 41, the two protrusions in the first jack 41 are connected with the male head of the first plug 6. The protrusions in the first jack 41 can reduce the contact area with the male head of the first plug 6, and reduce the resistance of the male head of the first plug 6 inserted into the first jack 41.

[0080] When the male head of the fourth plug 9 is inserted into the circular hole section 421 of the second jack 42, the two protrusions are in abutment with the male head of the fourth plug 9. The protrusions of the circular hole section 421 can reduce the contact area with the male head of the fourth plug 9, and reduce the resistance of the male head of the fourth plug 9 inserted into the circular hole section 421.

[0081] When the male head of the second plug 7 is inserted into the rectangular hole section 422, the male head of the second plug 7 is in abutment with the inner wall of the rectangular hole section 422.

[0082] When the male protrusions of the third plug 8 are inserted into the third socket 43, the two positioning protrusions 431 abut against the male protrusions of the third plug 8. The two positioning protrusions 431 can reduce the contact area with the male protrusions of the third plug 8, thereby reducing the resistance when the male protrusions of the third plug 8 are inserted into the third socket 43.
