[0066] Current drone chargers integrate multiple functional modules, which often require cables to connect to a power source and / or to each other. To address the maintenance-prone cable routing in current chargers, the present invention provides a charger body and charger that achieves simpler cable routing, reduces cable routing complexity, and facilitates maintenance.

[0067] See also Figure 1 , exemplarily illustrating the principle structure of the charger body provided by the present invention, the charger body 1 provided by the present invention may include a base 11 having a housing cavity 111, wherein the housing cavity 111 includes an opening 112 for inserting a battery. In addition, the base 11 also includes a first side portion 12 and a second side portion 13 located on the periphery of the housing cavity 111. It can be understood that the housing cavity 111 is mainly formed by the body of the base 11, and its periphery is at least a portion of the body that forms the cavity.

[0068] The first side portion 12 has a first cavity 121 for accommodating a first power module. The bottom wall of the first cavity 121 (the vertical plane near the accommodating cavity in the figure) extends vertically. Furthermore, a first wire groove 122 is formed on the bottom wall of the first cavity 121.

[0069] The second side portion 13 has a second cavity 131 for accommodating a second power module. Similar to the first cavity 121, the bottom wall of the second cavity 131 extends vertically. Furthermore, a second wire groove 132 is similarly formed on the bottom wall of the second cavity 131.

[0070] The base 11 also includes a channel 14 arranged between the first side portion 12 and the second side portion 13, and the two ends of the channel 14 are respectively connected to the first concave cavity 121 and the second concave cavity 131, so that it can be used as a routing space for thick cables and / or multiple wiring harnesses, and the wiring harnesses for further routing are distributed at the two concave cavities.

[0071] In the charger body provided by the present invention, a first concave cavity and a second concave cavity are provided on the base of the charger body for installation of corresponding power modules, and corresponding wire grooves are provided in the corresponding concave cavities for cable routing, thereby reducing the adverse effects of the installed cables on the power modules installed in the concave cavities. At the same time, a channel is also provided on the base to connect the first concave cavity with the second concave cavity. This channel can serve as a routing channel for the power modules or other modules installed on the first and second concave cavities, respectively. It supports the interconnection of cables between the power modules on both sides and supports the routing of other power modules through this channel, thereby facilitating the inspection and maintenance of the lines of the corresponding modules by relevant staff, reducing the difficulty and complexity of maintenance, and supporting the realization of simpler cable routing.

[0072] Preferably, the channel is located at the bottom of the base, and the first power module and the second power module here are preferably heat-generating power modules, such as power modules, and the structure of placing the heat-generating power module on the side of the base can help increase the space for the base to accommodate the battery. At the same time, it can help alleviate the situation where the traditional placement of the power module at the bottom of the base easily causes rapid heat accumulation, and the heat dissipation structure is more reasonable.

[0073] See also Figures 2 to 5 , exemplarily illustrating the structure of the charger body and charger provided by the present invention in a specific application example. Based on the aforementioned charger body structure, the charger body 2 in this specific application example also includes a base 21 having a receiving cavity 211. The base 21 also has a first side portion 22 and a second side portion 23. The first side portion 22 has a first concave cavity 221. Correspondingly, the second side portion 23 has a second concave cavity 231.

[0074] Figures 2 to 4 The bottom walls of the first and second concave cavities 221, 231 each have a square mounting surface for mounting a corresponding power module, such as the power module 4. Similar to the aforementioned charger main structure, a first wire groove 222 is provided in the first concave cavity 221, and a second wire groove 232 is provided in the second concave cavity 231.

[0075] A channel 24 is further provided between the first side portion 22 and the second side portion 23 , and the channel 24 is located on the bottom side of the base 21 . Accordingly, the potential safety hazard caused by the heat generated by the charger directly acting on the cable 3 during charging of the battery can be avoided.

[0076] In this specific application example, the base 21 may further include a third side portion 25, which includes a first mounting assembly 251 for mounting a third power module and a second mounting assembly 252 for mounting a fourth power module, wherein the second mounting assembly 252 is located on top of the first mounting assembly 251. Here, the third power module may be the heat dissipation module 5, and the fourth power module may be the control module 6.

[0077] A third wire-passing hole 254 is provided between the first mounting component 251 and the second mounting component 252, and the third wire-passing hole 254 extends from the location of the first mounting component 251 to the location of the second mounting component 252. When the heat dissipation module 5 is installed at the first mounting component 251 and the control module 6 is installed at the second mounting component 252, the third wire-passing hole 254 can be used for routing the control module 6 to control the power module 4 and the heat dissipation module 5. In addition, it can also provide routing for other cables 3 such as power supply cables. Of course, in another specific application example, a second wire-passing hole (not shown) similar to the third wire-passing hole can also be provided between the first mounting component 251 and the accommodating cavity 211. In this case, the second wire-passing hole extends from the location of the first mounting component 251 to the accommodating cavity 211.

[0078] More specifically, the first mounting assembly 251 may include a mounting plate 2511 and a surrounding plate 2512. The mounting plate 2511 is vertically arranged, with its surface perpendicular to the bottom wall of the first cavity 221. The surrounding plate 2512 is disposed around the mounting plate 2511. Accordingly, the first mounting assembly 251 has a third cavity 255 formed by the mounting plate 2511 and the surrounding plate 2512. The mounting plate 2511 is provided with a second through hole 256 that extends through the accommodating cavity 211. The second through hole 256 can be sized to match the fan of the heat dissipation module 5, allowing air supplied by the fan to flow quickly and unobstructed into the accommodating cavity 211.

[0079] In addition, a third cable trough 257 is provided on the enclosure 2512 for routing the cables 3 connecting the fans to the power module 4 and the control module 6, thereby reducing the number of unfixed cable locations and improving the stability of the electrical connection. Furthermore, a fourth cable hole 258 is provided on the bottom side of the mounting plate 2511. The fourth cable hole 258 communicates with the channel 24, further enriching the cable routing options and making them more flexible and practical.

[0080] In the present invention, the top sides of the first side portion 22 and the second side portion 23 may each be provided with a first wire hole 233. The first wire hole 233 may communicate with the accommodating cavity 211 or with the concave cavity on the side thereof. The first side portion 22 may also include a plurality of first through holes 224. The first wire groove 222 extends vertically, and the plurality of first through holes 224 are distributed on both sides of the first wire groove 222, and all of the plurality of first through holes 224 communicate with the accommodating cavity 211.

[0081] More specifically, two first wire-passing grooves 222 are provided on the first side portion 22. Similarly, two second wire-passing grooves 232 are provided on the second side portion 23. Here, the first through holes 224 are all rounded rectangular holes extending in the horizontal direction.

[0082] A mounting groove 225 is further defined within the first concave cavity 221. The mounting groove 225 is located on the top side of the two first wire-passing grooves 222 and in the direction in which the two first wire-passing grooves 222 extend. The mounting groove 225 is recessed toward the accommodating cavity 211 to form a vertically extending guide protrusion 213 within the accommodating cavity 211. A third through hole 2251 is defined in the recessed wall of the mounting groove 225 and extends through the accommodating cavity 211.

[0083] In the present invention, similar to the structure of the first concave cavity 221, a groove structure identical to the mounting groove 225 may be provided in the second concave cavity 231. This groove structure may be connected to the aforementioned first wire hole 233. Accordingly, the cable 3 routed through the second wire groove 232 may enter the accommodating cavity 211 from the groove structure and the first wire hole 233. Similarly, in the first concave cavity 221, the cable 3 routed through the first wire groove 222 may enter the accommodating cavity 211 from the mounting groove 225 and the first wire hole 233 on the side of the first concave cavity 221.

[0084] A guide assembly 26 may also be disposed within the mounting recess 225. The guide assembly 26 includes a guide bracket 261 and a roller 262 mounted on the guide bracket 261. At least a portion of the roller 262 is exposed within the accommodating cavity 211 through the third through-hole 2251. The axle of the roller 262 is perpendicular to the extension direction of the guide protrusion 213, meaning its rolling surface is parallel to the extension direction of the guide protrusion 213. The roller exposed within the accommodating cavity 211 can provide rolling guidance for batteries with matching guide groove structures, allowing for smoother, more natural, and more accurate placement of the batteries into the charger.

[0085] Furthermore, the guide bracket 261 is vertically arranged, and two fourth wire grooves 226 are formed between the guide bracket 261 and the side walls of the mounting groove 225 on both sides. The groove bodies of the two fourth wire grooves 226 are respectively located in the extension direction of the groove body of the first wire groove 222, and the groove bodies of the two fourth wire grooves 226 are connected with the corresponding groove bodies of the first wire groove 222. The cables 3 bundled from the channel 24 can be connected to relevant electrical appliances such as electrical connectors at the top of the first wire groove 222, the fourth wire groove 226 and the first wire hole 233 accommodating cavity 211, which makes the wiring simple and the space utilization rate higher.

[0086] Furthermore, limiting protrusions (not shown) are provided at the slots of the first wire trough 222 and the fourth wire trough 226. The limiting protrusions are protruded horizontally toward the opposite side of the trough body in which they are located, so that the width of the gap formed by the limiting protrusions and the slot wall on the opposite side is smaller than the width of the wire trough body itself, so that the cable 3 can be restricted to the corresponding wire trough space to a certain extent, and can avoid direct contact with the power module 4.

[0087] The present invention further provides a charger, which may include the charger body 2 as described above, and a corresponding power module and a cable 3 are installed on the charger body 2 .

[0088] In a specific application example of the charger, a first power module is mounted within the first cavity 211. This first power module is a power module 4. The power module 4 comprises a plate-shaped body with a vertically oriented surface, which can be mounted and fixed to the bottom wall of the corresponding cavity. Furthermore, a first cover 7 can be mounted on each of the first cavity 221 and the second cavity 231, covering the power module 4 and cooperating with the corresponding cavity to form a protective space for the power module 4.

[0089] For example, in a specific application example of the charger, a third power module is mounted on the third side portion 25. This third power module is a heat dissipation module 6, which includes multiple vertically arranged fans. Furthermore, a second cover 8 can be positioned over the third cavity 255, covering the heat dissipation module 6 and cooperating with the cavity to form a protective space for the heat dissipation module 6. It is understood that both the first cover 7 and the second cover 8 are covers with multiple air intake grilles to facilitate air circulation and heat dissipation.

[0090] In another specific application example of the charger, a first polarity electrical connector 27 and a second polarity electrical connector 28 are further provided on the top side of the first side portion 22 and the top side of the second side portion 23; the first polarity electrical connector 27 and the second polarity electrical connector 28 are both located in the opening 212. More specifically, referring to FIG. Figure 2 and Figure 3 The first polarity electrical connector 27 is disposed at the first wire hole 233 on the side of the first side portion 22. Accordingly, the connecting cable of the first polarity electrical connector 27 can pass through the first wire hole 233 into the fourth wire groove 226, and then pass through the fourth wire groove 226 and the first wire groove 222 to the channel 24. The second polarity electrical connector 28 is similarly configured and will not be described in detail here.

[0091] In addition, a mounting hole 29 communicating with the channel 24 is provided on the bottom side of the third side portion 25 , and an external power connection socket is provided in the mounting hole 29 , which can be directly connected to the mains electricity to facilitate direct charging of the power module and battery in the charger.

[0092] like Figure 4 and Figure 5 As shown, a battery 9 can be placed in the accommodating cavity 211 through the opening 212, and the charger can then begin charging. Due to the use of this charger body, most of the heat generated during the charging process does not directly affect the cables, reducing safety risks. Furthermore, if maintenance personnel need to maintain cables or related wiring components, they can quickly locate the corresponding location using the above-mentioned wire troughs, wire holes, and channels, making wiring very simple and clear, and facilitating maintenance.

[0093] 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.
