In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0047] In the plug-in connection operation of the electrical connection, the wrong plug-in connection can bring the adverse consequences of the damage of the electrical appliance. Therefore, the existing plug-in connection structure is usually provided with a foolproof structure to reduce the probability of wrong plug-in connection. However, in some plug-in connection operation scenes which are not convenient for controlling the plug-in action or the size of the plug-in force, the existing foolproof structure has the possibility of foolproof failure. In order to solve this problem, the plug-in connection device provided by the utility model can make the first plug-in piece realize the effect of just being plugged in the first direction, and realize the effect of the plurality of plug pieces just abutting in the second direction, so as to avoid the foolproof failure and prevent the situation of electrical appliance damage caused by wrong plug-in connection.

[0048] Referring to Figures 1 to 7 , the plug-in connection device provided by the utility model and the structure applied to the unmanned aerial vehicle are exemplarily shown, the plug-in connection device 1 can include a first plug-in piece 11 and a second plug-in piece 12, wherein:

[0049] A plurality of first insertion pieces 111 are arranged in a column on the first insertion piece 11, and a first insertion slot 112 is formed between two adjacent first insertion pieces 111. Figure 2 As shown in the figure, the first insertion piece 11 is arranged in a column in the first direction (i.e., the horizontal right direction in the figure), and the first insertion piece 111 on the left side is the first insertion piece 111 at the head of the column, and the last first insertion piece 111 on the right side is the first insertion piece 111 at the tail of the column. D 1 As shown in the figure, the first insertion piece 11 is arranged in a column in the first direction (i.e., the horizontal right direction in the figure), and the first insertion piece 111 on the left side is the first insertion piece 111 at the head of the column, and the last first insertion piece 111 on the right side is the first insertion piece 111 at the tail of the column.

[0050] Similarly, a plurality of second insertion pieces 121 are arranged in a column on the second insertion piece 12, and a second insertion slot 122 is formed between two adjacent second insertion pieces 121. Figure 2 As shown in the figure, the first insertion piece 11 is arranged in a column in the first direction (i.e., the horizontal right direction in the figure), and the first insertion piece 111 on the left side is the first insertion piece 111 at the head of the column, and the last first insertion piece 111 on the right side is the first insertion piece 111 at the tail of the column.

[0051] In use, the first insertion piece 11 and the second insertion piece 12 are configured to be inserted and connected in the first direction in which the first insertion pieces 111 are arranged in a column. D 1 In the first direction in which the first insertion pieces 111 are arranged in a column, each first insertion piece 111 is respectively inserted into a corresponding second insertion slot 122, and each second insertion piece 121 is respectively inserted into a corresponding first insertion slot 112, thereby achieving the insertion and connection operation between the first insertion piece 11 and the second insertion piece 12. Figure 3 In the second direction in which the first insertion pieces 111 are arranged in a column, i.e. D 2 In the second direction in which the first insertion pieces 111 are arranged in a column, i.e. D 1 In the second direction in which the first insertion pieces 111 are arranged in a column, i.e.

[0052] In the second direction in which the first insertion pieces 111 are arranged in a column, i.e. Figure 2 In the first direction, a first positioning column 123 is arranged at the head side of the column of the second insertion pieces 121, and a second positioning column 124 is arranged at the tail side of the column of the second insertion pieces 121.

[0053] The column body extension direction of the first positioning column 123 and the second positioning column 124 is the same as the sheet body extension direction of the second insertion sheet 121, as shown in the figure. Figure 2 As shown, they are all arranged in the vertical direction.

[0054] Figure 2 In the embodiment, corresponding to the positioning structure on the second insertion piece 12, a first positioning slot 113 is arranged at the side of the column of the first insertion sheet 111 on the first insertion piece 11, and the first positioning column 123 is inserted and matched with the first positioning slot 113. At the same time, a second positioning slot 114 is arranged at the side of the column of the first insertion sheet 111, and the second positioning column 124 is inserted and matched with the second positioning slot 114.

[0055] By using the first positioning column 123 and the second positioning column 124 arranged on the second insertion piece 12 and corresponding first positioning slot 113 and second positioning slot 114 arranged on the first insertion piece 11, the insertion alignment efficiency in the correct insertion direction between the first insertion piece 11 and the second insertion piece 12 can be improved, and the user experience of the corresponding electrical appliance during insertion is improved.

[0056] Further, a first guide slot 1231 is arranged on the first positioning column 123, and the slot body of the first guide slot 1231 is arranged along the extension direction of the first positioning column 123. Correspondingly, the first positioning slot 113 is provided with a slot wall matched with the first guide slot 1231. At the same time, two second guide slots 1241 are arranged on the second positioning column 124, and the slot bodies of the two second guide slots 1241 are arranged along the extension direction of the second positioning column 124. Correspondingly, the second positioning slot 114 is provided with a slot wall matched with the second guide slot 1241. Here, the column bodies of the first positioning column 123 and the second positioning column 124 are consistent, and by differentiating the slot body structures on the two positioning columns, a better foolproof effect can be achieved.

[0057] It can be understood that in some specific application examples, only the first positioning column 123 or the second positioning column 124 can be provided with a corresponding guide slot, which can also achieve a certain foolproof purpose.

[0058] In the embodiment, as shown in Figure 2 and Figure 3 The first insertion piece 11 can include a first base plate 115 and a plurality of first insertion sheets 111 arranged on the first base plate 115, and the first base plate 115 can be a rectangular plate body, and the first base plate 115 has a guide centering axis L1 perpendicular to the plate surface of the first base plate 115, and the first insertion sheets 111 are arranged on the first base plate 115 along the guide centering axis L1. Figure 2 , Figure 3In the embodiment, the first substrate 115 is just symmetrical about the guiding centering axis L1, that is, the guiding centering axis L1 coincides with the symmetry axis of the first substrate 115. It can be understood that the guiding centering axis L1 is a center line that makes the first connector 11 close to the second connector 12 in a direction and just enables the first connector 11 to be positionally aligned with the second connector 12 (but not plug-in aligned). In the embodiment, the guiding centering axis L1 is parallel to the symmetry axis of the first substrate 115. Figure 3 And Figure 4 In the embodiment, the guiding centering axis L1 also coincides with the center line of the second connector 12.

[0059] Of course, in some other specific application examples, the guiding centering axis L1 can not coincide with the symmetry axis of the first substrate 115, and the length of the first substrate 115 does not cause the guiding centering axis L1 to change.

[0060] Meanwhile, in the first connector 11, a plurality of the first tabs 111 are arranged in an array on the first substrate 115 in axial symmetry about a symmetry axis L2, that is, a first tab 111 is taken as a middle tab, and a corresponding number of first tabs 111 are distributed at equal intervals on both sides of the middle tab in the array direction, and the middle axis of the middle tab is the symmetry axis L2. Here, the symmetry axis L2 is perpendicular to the surface of the first substrate 115, so the guiding centering axis L1 is parallel to the symmetry axis L2, and the distance between the guiding centering axis L1 and the symmetry axis L2 in the array direction is a preset distance, so that the center axes of the plurality of first tabs are offset relative to the substrate of the connector body, so that the first connector 11 and the second connector 12 are in different plug-in directions, that is, in a plug-in state and in a butting state, wherein the plug-in state is a correct plug-in connection, and the butting state prevents incorrect plug-in between the two connectors.

[0061] In addition to the plug-in connection device 1 described above, the utility model also provides a unmanned aerial vehicle 2, the unmanned aerial vehicle 2 can include battery 21 and rack 22, and the plug-in connection device 1 as described above, correspondingly, the second connector 12 is arranged on the rack 22, and the first connector 11 is arranged on the battery 21.

[0062] As shown in Figure 7 The rack 22 can include a foot stand 221 and a mounting rack 222 arranged on the foot stand 221, and the mounting rack 222 is provided with a battery mounting seat (not shown in the figure) for the battery to be inserted and fixed. Further, the battery mounting seat can include a first seat body 223 and a second seat body 224 arranged at intervals, and a containing space 225 for the battery 21 to be inserted is formed between the first seat body 223 and the second seat body 224. Here, the second connector 12 is arranged on the top of the first seat body 223 and the second seat body 224, respectively.

[0063] In combinationFigure 1 、 Figure 2 and Figure 7 The second plug-in part 12 can include a mounting plate 125 and a plurality of connecting legs 126, the plurality of connecting legs 126 are fixedly connected with the plate edge circumferential side of the mounting plate 125, and the plurality of second plug-in pieces 121 are mounted on the mounting plate 125. Here, the number of connecting legs 126 is four, and the four connecting legs 126 are respectively arranged at the column head side and the column tail side of the plurality of first plug-in pieces 121 in two groups.

[0064] Preferably, a reserved gap 127 is further arranged between the bottom plate surface of the mounting plate 125 and the top of the seat body, which can provide a deformation space for the mounting plate 125, thereby providing a buffer for the placement of the battery 21.

[0065] In the utility model, the opposite sides of the first seat body 223 and the second seat body 224 are provided with the guide bosses 2241 protruding towards each other, the table surfaces of the two guide bosses 2241 are arranged in parallel and vertically. The guide bosses 2241 are arranged in extension in the height direction, and the buffer pads 2242 are further arranged on the top side end surfaces of the guide bosses 2241, which can also provide a buffer for the placement of the battery 21, thereby reducing the risk of impact damage when the battery 21 is placed.

[0066] As shown in Figure 6 The battery 21 can include a battery body 211 and ear parts 212 arranged on both sides of the top of the battery body 211, and the first plug-in parts 11 are arranged on the bottoms of the two ear parts 212. Further, the side of the battery body 211 is provided with a guide groove 2111, and the connection between the ear part 212 and the battery body 211 is located on the top side of the groove extension direction of the guide groove 2111, and the guide groove 2111 cooperates with the guide boss 2241 on the corresponding seat body, thereby facilitating the user to quickly place the battery 21.

[0067] In the utility model, the second plug-in parts 12 on the two seat bodies are preferably arranged on the same axis at the same horizontal height, that is, the two second plug-in parts 12 are arranged in the same XY plane, and the plurality of second plug-in pieces 121 thereof are arranged in columns in the Z-axis direction. At the same time, the two second plug-in parts 12 are also located in the same XZ plane. Correspondingly, the guide groove 2111 on the battery 21 and the first plug-in parts 11 on the two ear parts 212 are all in the same XZ plane, and more specifically, the vertical center lines of the guide groove 2111 and the two ear parts 212 and the guide center axis are all in the same XZ plane.

[0068] Therefore, when the battery 21 is inserted in the forward direction, the two second connectors 12 and the two first connectors 11 are located in the same XZ plane under the cooperation of the guide bosses 2241 and the guide grooves 2111. At this time, if the first connector 11 is inserted in the above-mentioned D 1 direction, the first connectors 11 and the second connectors 12 can form the insertion state. If the battery 21 is inserted in the reverse direction, the two second connectors 12 and the two first connectors 11 are also located in the same XZ plane under the cooperation of the guide bosses 2241 and the guide grooves 2111. At this time, the first connector 11 on the battery 21 is inserted in the D 2 direction (opposite to the above-mentioned D 1 direction), although the connectors are located in the same plane, the plurality of insertion pieces on the first connector 11 are offset with respect to the axis of symmetry L2, so that the first connectors 11 and the second connectors 12 form the abutting state, thereby avoiding the error insertion of the first connectors 11 and the second connectors 12, and the probability of the foolproof failure is smaller, the structure is relatively more stable and safer.

[0069] It can be understood that, on the battery 21, the two installation positions for installing the two first connectors 11 are located on the middle XZ plane of the battery 21. Correspondingly, when the battery 21 is inserted in the forward direction or the reverse direction, the two installation positions are located on the same middle XZ plane, and only the insertion piece columns in the two connectors are exchanged.

[0070] Finally, it should be noted that the above-mentioned embodiments are only specific embodiments of the present application, which are used to illustrate the technical solutions of the present application, but not to limit the present application. The protection scope of the present application is not limited to this. Although the present application has been described in detail with reference to the above-mentioned embodiments, those skilled in the art should understand that any person skilled in the art can modify or easily think of changes to the technical solutions recorded in the above-mentioned embodiments within the technical range disclosed by the present application, or make equivalent replacement to some technical features.
