DETAILED DESCRIPTION

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0025] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention 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 cannot be understood as a limitation on the present invention.

[0026] In addition, 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. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0027] With the continuous development of small household and commercial appliances, in order to meet the demand for more convenient use, some of them have developed into rechargeable appliances, so that the appliances are not restricted by power cords when working and have a wider working range. For example, appliances such as sweepers, mops, and lawn mowers will automatically return to the charging station to charge when the battery is low. However, when the lawn mower is working, there will be dirt such as mud, grass clippings, and vines in the working environment. When the dirt sticks to the drive wheel, it will cause the height of the lawn mower to change. The unstable height of the body may cause unstable contact with the charging contacts, resulting in failure to charge.

[0028] In order to alleviate the above technical problems, the utility model proposes a new charging structure and charging seat, which can charge sweepers, mops, lawn mowers and other electrical appliances to be charged. The charging structure includes a main shell 10 and a mobile shell 20. The mobile shell 20 is provided with a charging contact 30, and the mobile shell 20 can move in the first direction relative to the main shell 10. When the electrical appliance to be charged contacts the charging contact 30 of the charging structure, the electrical appliance to be charged can be charged. By setting the first elastic member 40 and the second elastic member 50, the position of the charging contact 30 can be changed in the first direction. When the height of the electrical appliance to be charged changes, the charging contact 30 can also be in conductive contact with the electrical appliance to be charged to avoid poor contact and ensure the stability of charging.

[0029] The charging structure provided in the embodiment of the utility model is now described.

[0030] Please also read Figures 1 to 3 The charging structure includes a main housing 10 , a moving housing 20 , a first elastic member 40 and a second elastic member 50 .

[0031] The main housing 10 is fixedly arranged, and the main housing 10 is a fixed part of the charging structure. After the charging structure is installed and fixed, its position remains unchanged. The main housing 10 can be a one-piece structure or a multi-piece structure, and its specific structure is not limited here.

[0032] The mobile housing 20 can move in a first direction relative to the main housing 10, and a charging contact 30 is arranged on the mobile housing 20. When the mobile housing 20 moves along the first direction, the charging contact 30 also moves along the first direction, thereby changing the position of the charging contact 30 to adapt to the position change of the charging part of the electrical appliance to be charged. Since the charging contact 30 needs to contact the charging part of the electrical appliance to be charged, the charging contact 30 is exposed, and the charging contact 30 is correspondingly arranged on the part of the mobile housing 20 exposed from the main housing 10. Among them, the first direction can be a vertical direction, a horizontal direction, etc.

[0033] A first elastic member 40 and a second elastic member 50 are arranged between the mobile housing 20 and the main housing 10, that is, the two ends of the first elastic member 40 are respectively connected to the mobile housing 20 and the main housing 10, and the two ends of the second elastic member 50 are also respectively connected to the mobile housing 20 and the main housing 10. However, the deformation trends of the first elastic member 40 and the second elastic member 50 are always opposite. When the mobile housing 20 moves in the first direction, one of the first elastic member 40 and the second elastic member 50 is extended and the other is shortened. Specifically, the extension and shortening of the first elastic member 40 and the second elastic member 50 are both in the first direction. The deformation directions of the first elastic member 40 and the second elastic member 50 are both in the first direction. The arrangement of the first elastic member 40 and the second elastic member 50 enables the charging contact sheet 30 on the mobile housing 20 to always be tightly arranged with the charging part of the electrical appliance to be charged under the action of the elastic member, thereby reducing the phenomenon of poor charging contact. At the same time, since the deformation trends of the first elastic member 40 and the second elastic member 50 are opposite, the travel of the mobile housing 20 can be made more unrestricted.

[0034] When the appliance to be charged is ready to be charged, the charging part of the appliance to be charged may be misaligned with the charging contact piece 30 of the charging structure due to dirt or assembly and manufacturing tolerances. When using the charging structure provided by the utility model, even if the charging part and the charging structure are not facing each other, the charging part pushes the charging structure until the two are facing each other as the two gradually approach each other, or a guiding structure is provided between the appliance to be charged and the charging structure so that the two gradually approach each other and guide each other until the charging part and the charging structure are facing each other. As the two gradually face each other, the positions of the movable housing 20 and the charging contact piece 30 in the first direction are continuously adjusted, and the compression or stretching of the first elastic member 40 and the second elastic member 50 changes, thereby ensuring close contact between the charging part and the charging structure.

[0035] The charging structure in the above embodiment includes a main housing 10 and a mobile housing 20, the mobile housing 20 can move in a first direction relative to the main housing 10, a charging contact piece 30 is arranged on the mobile housing 20, and a first elastic member 40 and a second elastic member 50 are respectively arranged between the mobile housing 20 and the main housing 10. When charging an electrical appliance such as a lawn mower, if the charging part of the electrical appliance is not directly opposite to the charging contact piece 30 in the first direction, the position of the mobile housing 20 can be changed by the first elastic member 40 and the second elastic member 50, so that the charging part of the electrical appliance is directly opposite to the charging contact piece 30, thereby ensuring that the electrical appliance remains stable during charging and improving the charging efficiency.

[0036] In some embodiments of the present invention, please refer to Figures 2 to 5 The main housing 10 has a receiving cavity and a cavity opening 13 connecting the receiving cavity to the outside. The mobile housing 20 includes an inner mounting portion 22 and an outer mounting portion 21 connected to each other. The inner mounting portion 22 is arranged inside the main housing 10. The outer mounting portion 21 extends to the outside of the main housing 10 through the cavity opening 13. The charging contact piece 30 is fixed to the outer mounting portion 21. The main housing 10 has a receiving cavity inside. The main housing 10 also has a cavity opening 13. The cavity opening 13 connects the outside and the receiving cavity. The outer mounting portion 21 extends to the outside of the main housing 10 through the cavity opening 13. It can be understood that the mobile housing 20 is divided into the outer mounting portion 21 and the inner mounting portion 22 at the cavity opening 13.

[0037] By configuring the mobile housing 20 as the inner mounting portion 22 and the outer mounting portion 21 , at least a portion of the mobile housing 20 is located inside the main housing 10 , so that the movement of the mobile housing 20 is more stable and the charging contact piece 30 is conveniently installed and fixed.

[0038] In some embodiments, the length direction of the inner installation portion 22 is parallel to the first direction, so that the inner installation portion 22 and the main housing 10 always have a longer contact space, making the movable housing 20 more stable when moving.

[0039] In some embodiments, the length direction of the external mounting portion 21 is perpendicular to the first direction, so that the charging contact piece 30 can be installed at a position far away from the main housing 10 to meet the charging requirements of different types of electrical appliances to be charged. For example, in some electrical appliances to be charged, the charging part is not arranged at the outermost side of the electrical appliance, but has a certain distance from the outermost side of the electrical appliance, which requires the external mounting portion 21 to extend a certain length in a direction perpendicular to the first direction so that the charging contact piece 30 can contact the charging part.

[0040] In some embodiments, one of the side walls of the inner mounting portion 22 and one of the side walls of the main shell 10 are closely arranged, and the two adjacent side walls are parallel to the first direction. In this way, when the movable shell 20 moves along the first direction, the two adjacent side walls can guide the movement of the movable shell 20.

[0041] In some embodiments of the present invention, please refer to Figure 2 and Figure 3 , the first elastic member 40 is arranged inside the inner mounting portion 22, and the second elastic member 50 is arranged inside the main housing 10 and outside the inner mounting portion 22. The inner mounting portion 22 has a containing space inside for the first elastic member 40 to be installed and fixed, and the second elastic member 50 is arranged between the inner wall of the main housing 10 and the outer wall of the inner mounting portion 22. It should be noted that the first elastic member 40 is arranged inside the inner mounting portion 22, and since one end thereof needs to be connected to the main housing 10, one end of the first elastic member 40 can extend to the outside of the inner mounting portion 22 to be connected to the main housing 10, or can be indirectly connected to the main housing 10 through the transition member 70.

[0042] By arranging the first elastic member 40 inside the inner mounting portion 22 and the second elastic member 50 outside the inner mounting portion 22, the distribution positions of the first elastic member 40 and the second elastic member 50 are different, which is convenient for installation and makes it easier to achieve opposite deformation trends of the two elastic members when the movable shell 20 moves.

[0043] In some embodiments of the present invention, please refer to Figure 3 and Figure 5 The charging structure further includes a transition piece 70. The inner mounting portion 22 has a partition structure 24. The partition structure 24 and the inner mounting portion 22 together form a mounting cavity 240. The first elastic member 40 is disposed in the mounting cavity 240. One end of the transition piece 70 is located in the mounting cavity 240 and connected to the first elastic member 40. The other end of the transition piece 70 extends to the inner mounting portion 22 and abuts against the main housing 10. The partition structure 24 is disposed inside the inner mounting portion 22 so that the inner portion of the inner mounting portion 22 is divided to form the mounting cavity 240. Part of the inner wall of the mounting cavity 240 is the inner wall of the inner mounting portion 22, and another part of the inner wall of the mounting cavity 240 is the side wall of the partition structure 24. The mounting cavity 240 is used to accommodate the first elastic member 40. At the same time, part of the transition piece 70 is located inside the mounting cavity 240, and part of it is located outside the mounting cavity 240 and abuts against the main housing 10. One end of the transition piece 70 located in the installation cavity 240 is connected to the first elastic piece 40 , and the “connection” here can be understood as abutment, fixed connection, detachable connection, etc.

[0044] By disposing the partition structure 24 , the first elastic member 40 can be disposed inside the inner mounting portion 22 , and the first elastic member 40 can be indirectly connected to the main housing 10 through the transition member 70 .

[0045] In some embodiments of the present invention, please refer to Figure 3 The transition piece 70 includes a first transition portion 71 and a second transition portion 72 connected to each other. The first transition portion 71 is arranged inside the mounting cavity 240, and the second transition portion 72 is arranged outside the mounting cavity 240, that is, arranged outside the inner mounting portion 22 and arranged inside the main housing 10. The inner mounting portion 22 is provided with a protruding hole 26, and the second transition portion 72 is arranged through the protruding hole 26. The size of the cross section of the first transition portion 71 is larger than the size of the cross section of the protruding hole 26, and the size of the cross section of the second transition portion 72 is smaller than the size of the cross section of the protruding hole 26, so that the second transition portion 72 can pass through the protruding hole 26, but the first transition portion 71 cannot pass through the protruding hole 26. The inner wall of the main housing 10 is provided with a limiting portion 14 for abutting against the second transition portion 72. When the movable housing 20 moves toward the limiting portion 14, the second transition portion 72 abuts against the limiting portion 14, and the first elastic member 40 is compressed and deformed.

[0046] The size of the cross section of the first transition portion 71 is larger than the size of the extension hole 26, which means that the first transition portion 71 cannot pass through the extension hole 26. For example, the cross sections of the first transition portion 71 and the extension hole 26 are both circular, and the diameter of the cross section of the first transition portion 71 is larger than the diameter of the cross section of the extension hole 26. For example, the cross sections of the first transition portion 71 and the extension hole 26 are both square, and the side length of the cross section of the first transition portion 71 is larger than the side length of the cross section of the extension hole 26. The size of the cross section of the second transition portion 72 is smaller than the size of the extension hole 26, which means that the second transition portion 72 can pass through the extension hole 26. For example, the cross sections of the second transition portion 72 and the extension hole 26 are both circular, and the diameter of the cross section of the second transition portion 72 is smaller than the diameter of the cross section of the extension hole 26. For example, the cross sections of the second transition portion 72 and the extension hole 26 are both square, and the side length of the cross section of the second transition portion 72 is smaller than the side length of the cross section of the extension hole 26.

[0047] By disposing the first transition portion 71 and the second transition portion 72 , the transition piece 70 will not fall out of the extension hole 26 and can also abut against the limiting portion 14 on the main shell 10 .

[0048] In some embodiments, the limiting portion 14 is formed by extending the inner wall of the main shell 10 in a direction perpendicular to the inner wall, forming the limiting portion 14 protruding from the inner wall of the main shell 10, so that the transition piece 70 can be stopped and limited.

[0049] In some embodiments, the cross section of the first transition portion 71 may be square, circular, etc. The cross section of the second transition portion 72 may be angular, circular, etc. The cross sections of the first transition portion 71 and the second transition portion 72 may be the same or different.

[0050] In some embodiments of the present invention, please refer to Figure 2 and Figure 4 , a first connection part 25 is provided on the inner mounting part 22, a second connection part 15 is provided protrudingly on the inner wall of the main housing 10, and two ends of the second elastic member 50 are connected to the first connection part 25 and the second connection part 15 respectively. The first connection part 25 and the second connection part 15 are arranged at intervals in the first direction, so that the expansion and contraction direction of the second elastic member 50 is arranged along the first direction. Among them, the second connection part 15 is provided protrudingly on the inner wall of the main housing 10, and the first connection part 25 has the following two situations: the first one is that the first connection part 25 is provided on the outer wall of the inner mounting part 22, that is, the first connection part 25 is provided protrudingly on the outer surface of the inner mounting part 22; the second one is that the outer wall of the inner mounting part 22 is recessed inward to form a recessed cavity, and the first connection part 25 is provided in the recessed cavity, so that the first connection part 25 is provided in a hidden arrangement.

[0051] In some embodiments, the first connection part 25 and the second connection part 15 are both positioning columns, and both ends of the second elastic member 50 are provided with hanging rings, which are hung on the corresponding positioning columns, so that the two ends of the second elastic member 50 can be respectively connected to the first connection part 25 and the second connection part 15.

[0052] In some embodiments, the first elastic member 40 and the second elastic member 50 are both cylindrical springs.

[0053] In some embodiments of the present invention, please refer to Figure 2 and Figure 3 , a cable 60 is welded on the charging contact sheet 30, and the cable 60 extends into the interior of the main housing 10. One end of the cable 60 is conductively connected to the charging contact sheet 30 by welding, and the other end of the cable 60 is connected to the main board and other structures inside the main housing 10, so that power can be supplied to the appliance to be charged through the cable 60 and the charging contact sheet 30. The conductive connection method of the cable 60 connecting the charging contact sheet 30 and the main board is more reliable and is not prone to poor contact.

[0054] In some embodiments of the present invention, the charging contact piece 30 is an elastic contact piece. When the charging contact piece 30 and the appliance to be charged come into contact with each other, the charging contact piece 30 is squeezed and slightly deformed. Under the action of the elastic force, the charging contact piece 30 and the appliance to be charged will press against each other, making charging more reliable.

[0055] In some embodiments of the present invention, please refer to Figures 3 to 5The outer mounting portion 21 has a cable channel 23, and the cable 60 is arranged along the cable channel 23. The cable channel 23 can guide the cable 60, avoid the cable 60 being arranged in a disorderly manner in the charging structure, and facilitate subsequent maintenance and replacement. The specific structure of the cable channel 23 is not limited here, and the cross-section can be circular, square, etc.

[0056] In some embodiments of the present invention, please refer to Figure 1 The main housing 10 includes a first part 11 and a second part 12 that are detachably connected. The first part 11 and the second part 12 are formed separately and then assembled to form the main housing 10. By dividing the main housing 10 into a two-piece design, the processing and manufacturing of the main housing 10 can be simplified and the processing cost can be lowered.

[0057] In some embodiments, the first part 11 and the second part 12 are connected and fixed by connecting members such as screws.
