[0050] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0051] In the description of the embodiments of the present invention, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0052] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0053] As the power consumption of drones increases, the size and weight of batteries increase significantly. Therefore, in the scenario of removing the battery, the operator needs to use a lifting method to remove the battery from the drone. Accordingly, when installing the battery on the drone, the operator is also required to lift the battery to a certain height, and then carefully place the battery in the corresponding position so that the electrical connector on the drone is connected to the corresponding electrical connector on the battery, thereby providing support for subsequent electrical connections. The rack structure provided by the utility model can avoid the problem of misalignment due to carelessness or other reasons during the battery placement process, and reduce the risk of damage to the electrical connector.

[0054] See also Figures 1 to 6 , exemplarily illustrating the rack provided by the present invention and its application to a drone (unmanned aerial vehicle). The rack 1 provided by the present invention may include a rack body 11, and may also include a first base 12 and a second base 13 spaced apart and mounted on the rack body 11. A mounting gap 16 for inserting a battery 3 is formed between the first base 12 and the second base 13, and the mounting gap 16 is located on the outer periphery of the rack body 11.

[0055] The first base 12 has a first side portion 121 and a first top portion 122, and the second base 13 has a second side portion 131 and a second top portion 132. The first side portion 121 and the second side portion 131 are arranged facing each other. At the same time, a first guide portion 123 is also provided on each of the first side portion 121 and the second side portion 131 to provide guidance for the placement of the battery 3.

[0056] The first top portion 122 is provided with a first polarity connector 14 , and the second top portion 132 is provided with a second polarity connector 15 . The first polarity connector 14 and the second polarity connector 15 are both provided with a second guide portion 144 for guiding the connector of the battery 3 .

[0057] In this utility model, a mounting gap for battery insertion is provided on the outer periphery of the frame body. Without occupying the operating load space, the first guide portions 123 on the two base bodies provide a primary guide for battery 3 insertion, facilitating rough positioning of the connector on battery 3. Simultaneously, a second guide portion 144 provided at the end of the connection guides the connector on battery 3, thereby achieving precise positioning between the connector on battery 3 and the corresponding polarity connector, thus avoiding misalignment and reducing the risk of damage to the electrical connector.

[0058] like Figures 1 to 3 As shown, the first guide portion 123 may include a guide protrusion 1231 extending and distributed in the height direction (i.e., the Z direction), and the protruding direction of the guide protrusion 1231 is perpendicular to the extending distribution direction. Accordingly, the guide protrusion 1231 on the first side portion 121 and the guide protrusion 1231 on the second side portion 131 are arranged to protrude toward each other.

[0059] Specifically, the guide protrusion 1231 extends in the Z direction and includes a guide surface 1232. Multiple through-holes 1233 are provided at various locations along the height of the guide surface 1232. Rollers or rolling balls (not shown) are positioned within the through-holes 1233, at least partially exposed from the guide surface 1232 to provide smoother rolling contact guidance. The guide surface 1232 in the figure is a vertical ZY plane that faces the opposite second base 13 in the direction of the protrusion of the guide protrusion 1231 (i.e., the X direction). The guide surface 1232 faces the corresponding guide surface on the opposite second base 13. Furthermore, the top end surface of the guide protrusion 1231 is also flat and may be provided with a cushioning pad 124 to provide cushioning support. The through-holes 1233 are square holes that extend from the guide surface 1232 through the base.

[0060] Here, the installation gap 16 formed between the first and second base bodies 12, 13 is a semi-open structure. This structure, located outside the frame body 11, supports the securement of the battery 3, avoiding the occupation of load installation space while also reducing the weight of the fixture. Furthermore, it facilitates the installation of other hardware and / or necessary protective components around the battery, enhancing functional scalability.

[0061] In a preferred embodiment of the present invention, the first polarity connector 14, the second polarity connector 15 and the two guide protrusions 1231 are all located in the same vertical plane, that is, the same XZ plane in the figure, so that the battery can be constrained as much as possible to move up and down in the XZ plane under the guidance of one of the components, making alignment more convenient.

[0062] like Figure 2 and Figure 5 As shown, the second guide portion 144 may include a guide column 1441 for plugging and mating the connector of the battery 3. The guide column 1441 is extended in the height direction. The guide column 1441 can provide guidance for the corresponding slots or holes on the battery 3 to achieve precise alignment between the connectors, thereby avoiding damage to the connector due to inaccurate insertion position.

[0063] Here, the first polarity connector 14 may include a connection seat, which may specifically include a mounting plate 141 and four connection legs 142, and the four connection legs 142 are all arranged at the two end positions of the mounting plate 141 in the Y-axis direction. The four connection legs 142 are all fixedly connected to the plate edge side of the mounting plate 141, and a reserved gap 143 is provided between the bottom plate surface of the mounting plate 141 and the first top 122. The reserved gap 143 can provide a certain deformation space for the mounting plate 141, thereby supporting the mounting plate 141 to provide a buffer for the placement of the battery 3. It is understandable that in other specific application examples, the number of the connection legs 142 can also be eight. In this case, at least two connection legs 142 are connected to each of the four plate edges of the mounting plate 141.

[0064] In the first polarity connector 14, a plurality of the inserts 1443 are mounted in a row on the corresponding mounting plate 141. Figure 1 、 Figure 2 In the embodiment, multiple inserts 1443 are arranged in a row along the Y-axis, and the spacing between adjacent inserts is uniform. The guide posts 1441 are located at the beginning and / or end of the row of multiple inserts 1443, and the guide posts 1441 are spaced apart from adjacent inserts 1443. Here, the provision of corresponding guide posts at both the beginning and end of the row of multiple inserts 1443 can achieve the best guiding effect on the connector. Of course, in other specific application examples, the provision of the guide posts 1441 only at the beginning or end of the row can also achieve a certain guiding effect.

[0065] Furthermore, the guide post 1441 may be provided with a guide groove 1442. The guide groove 1442 may extend in the direction of extension of the guide post 1441, that is, also in the Z-axis direction, with the opening of the guide groove 1442 facing the insert 1443. The guide groove 1442 may be provided to match the shape of the connector, thereby improving the accuracy of the alignment between the connectors.

[0066] It is understandable that the guide post 1441 at the head of the column can be set to a single guide groove 1442, while the guide post 1441 at the tail of the column can be set to multiple guide grooves 1442 to achieve directional distinction and achieve a fool-proof effect.

[0067] In the present invention, the frame body 11 may include a foot frame 112 and a mounting frame 111. Figure 1As shown, the mounting frame 111 may include a front mounting beam 1111 and a rear mounting beam 1112 , wherein the front mounting beam 1111 is mainly used for mounting the machine head, and the aforementioned first seat body 12 and the second seat body 13 are both mounted on the rear side of the rear mounting beam 1112 .

[0068] In addition, the mounting frame 111 also includes a first longitudinal beam 1113 and a second longitudinal beam 1114. The front end portion of the first longitudinal beam 1113 and the front end portion of the second longitudinal beam 1114 are respectively connected to the two ends of the mounting front beam 1111, while the rear end portion of the first longitudinal beam 1113 and the rear end portion of the second longitudinal beam 1114 are respectively connected to the two ends of the mounting rear beam 1112.

[0069] The first longitudinal beam 1113 also has a first extension portion 1115 connected to the rear end portion of the first longitudinal beam 1113. Similarly, the second longitudinal beam 1114 also has a second extension portion 1116 connected to the rear end portion of the second longitudinal beam 1114. The aforementioned first seat body 12 is arranged on the first extension portion 1115, and the second seat body 13 is arranged on the second extension portion 1116.

[0070] Each of the first and second base bodies 12, 13 includes a clamping end. The clamping end and the first guide portion 123 are located at either end of the base body along the X-axis. The clamping openings of the clamping end each match the size of the corresponding extension portion, and a plurality of bolts can be used to secure the two. Furthermore, a plurality of hollow portions 125 can be provided on the first and second base bodies 12, 13 to reduce the weight of the base bodies, thereby helping to reduce the weight of the frame 1.

[0071] like Figure 3 、 Figure 4 and Figure 6 As shown, the present invention further provides a UAV, which is specifically an unmanned aerial vehicle, which may include the frame 1 as described above, and a battery 3 is further installed on the frame 1.

[0072] The battery 3 may include a battery body 31 and a first ear 32 and a second ear 33 located on both sides of the top of the battery body 31, respectively. The two ears and the projection of the battery body 31 on the horizontal plane at least partially do not overlap, and the area corresponding to the non-overlapping is the installation area of the corresponding connector.

[0073] Corresponding to the aforementioned first guide portion 123 structure, the two sides of the battery body 31 are provided with first guide matching portions 311 for guiding and matching with the first guide portion 123, wherein the first guide matching portion on one side is arranged on the lower side of the first ear 32, and the first guide matching portion on the other side is arranged on the lower side of the second ear 33.

[0074] Corresponding to the aforementioned second guide portion 144 structure, a first connector 34 that is plugged into and mated with the first polarity connector 14 is provided on the first ear portion 32, and a second connector that is plugged into and mated with the second polarity connector 15 is provided on the second ear portion 33 (not shown in the figure, the structure can refer to the first connector). The first connector 34 and the second connector both have a second guide mating portion that is guided and mated with the corresponding second guide portion 144. The second guide mating portion can be a slot or a hole that is plugged into and mated with the aforementioned guide column 1441.

[0075] It is understandable that in other specific application examples, the drone may also be an unmanned vehicle, which also uses the frame 1 as described above and has batteries installed at corresponding positions.

[0076] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solutions of the present invention rather than to limit it. The protection scope of the present invention is not limited thereto. Although the present invention has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that any technician familiar with this technical field can still modify the technical solutions recorded in the aforementioned embodiments within the technical scope disclosed by the present invention, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be covered by the protection scope of the present invention.
