Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Existing charging devices typically expose the live output terminals, which can cause short circuits due to external environmental influences. This is extremely dangerous for users. In addition, touching the exposed output terminals with fingers or metal objects is also very dangerous and can easily lead to electric shock.

[0046] Please see Figure 1This invention provides a charging device 1, which can convert alternating current into a specific required voltage. The charging device 1 can output a single voltage to power a specific electronic device simultaneously, or it can output multiple voltages simultaneously, for example, charging a specific household appliance and a battery pack at the same time, or charging common electronic devices such as tablets and computers. In this embodiment, the charging device 1 is used to charge a battery pack 3.

[0047] Please see Figures 2 to 4 The charging device 1 includes: a housing 10, a circuit board (not shown), an output section 205, and an output protection device 300. The housing 10 includes, for example, a first housing 110, a second housing 120, and a third housing 130. The first housing 110 and the second housing 120 are fastened together to form a receiving cavity with an opening on one side, and the third housing 130 is engaged with the opening, thereby forming a closed receiving cavity. A recess 320 is provided on the side of the first housing 110 opposite to the receiving cavity for accommodating the battery pack 3. Guide rails 116 can be vertically provided on both sides of the recess 320. The guide rails 116 can cooperate with the structure of the two sides of the battery pack 3, allowing the battery pack 3 to slide into the recess 320 through the guide rails 116 and be fixed to the first housing 110.

[0048] Please see Figure 2 and Figure 3The housing 10 contains a circuit board (not shown) within its cavity. Multiple output sections 205 are connected to the circuit board and protrude through the housing 10. Each output section 205 includes multiple output terminals that engage with terminals on the battery pack 3, allowing charging of the battery pack 3. The output power range of the output terminals is, for example, 10W to 200W, and the output current range is, for example, 0.5A to 10A. The output terminals are, for example, exposed metal terminals. An output protection device 300 is provided outside the housing 10, ensuring that the output sections 205 are exposed when charging the battery pack 3 and covered by the output protection device 300 when not charging. Specifically, when charging the battery pack 3 is required, the charging interface of the battery pack 3 is electrically connected to the output section 205 of the circuit board to charge the battery pack 3. When the battery pack 3 is placed in the recess 320, the output section 205 is exposed, and the charging device 1 connects to the battery pack 3 to charge it. After charging is complete, the battery pack 3 is disconnected from the output section 205, and the battery pack 3 is removed from the recess 320, covering the output section 205. This greatly improves the safety and ease of use of the charging device 1. The charging device 1 may also have multiple charging interfaces, with internal components or terminals for power connection, such as USB connection terminals, current input terminals, etc. In this invention, the outer shell 10 is made of a non-conductive material, such as rigid plastic, or other non-conductive materials. In a specific embodiment of the invention, the outer shell 10 is made of acrylonitrile butadiene styrene plastic (ABS). This material has excellent impact resistance, heat resistance, low-temperature resistance, chemical resistance, and electrical properties. It is also easy to process, has stable product dimensions, good surface gloss, and is easy to paint and color, and is easy to process again.

[0049] Please see Figure 2 , Figures 5 to 7The present invention provides an output protection device 300, which is disposed on a charging device 1. The output protection device 300 includes a sliding part 301 and a fixing part 307. The fixing part 307 is disposed in the receiving cavity of the outer shell and is fixedly connected to the inner side of the first housing 110. The sliding part 301 is disposed between the fixing part 307 and the first housing 110, allowing the sliding part 301 to slide between a first position and a second position on the fixing part 307. One end of the output part 205 passes through the fixing part 307, the sliding part 301 and the first housing 110 in sequence, and is exposed in the first housing 110. When the sliding part 301 is in the first position relative to the fixing part 307, the sliding part 301 covers the output part 205. When the sliding part 301 is in the second position relative to the fixing part 307, the output part 205 is at least partially exposed by the sliding part 301.

[0050] Please see Figures 5 to 7 and Figure 10 In some embodiments, the first housing 110 may be provided with an opening 115, and one end of the output part 205 passes through the fixing part 307, the sliding part 301 and the opening 115 on the first housing 110 in sequence, and is exposed outside the first housing 110.

[0051] Please see Figure 10 In some embodiments, the inner side of the first housing 110 may be provided with multiple first grooves 302, which extend along the sliding direction of the sliding portion 301. In this embodiment, the inner side of the first housing 110 is provided with two first grooves 302, which are located on one side of the opening 115. In this embodiment, the two first grooves 302 are located above the opening 115, and the two first grooves 302 are parallel to each other and have equal lengths.

[0052] Please see Figure 6 , Figures 9 to 11 In some embodiments, the sliding portion 301 is positioned near the opening 115 and bends toward the opening 115 to form a sliding protrusion 304 that engages with the opening 115. The sliding protrusion 304 is inserted into the opening 115 and is allowed to slide within the opening 115. By sliding the sliding protrusion 304 within the opening 115, the output portion 205 can be covered or exposed.

[0053] Please see Figures 9 to 11In some embodiments, a plurality of sliding posts 309 perpendicular to the plane of the sliding portion 301 are provided on the side of the sliding portion 301 opposite to the sliding protrusion 304, and the plurality of sliding posts 309 are located on the side of the sliding portion 301 away from the sliding protrusion 304. In this embodiment, for example, two sliding posts 309 may be provided on the sliding portion 301, and the two sliding posts 309 are respectively located on both sides of the opening 115.

[0054] Please see Figure 9 In some embodiments, the sliding protrusion 304 forms multiple L-shaped slits 314 on the side near the sliding post 309. One side of the L-shaped slit 314 is located on the sliding protrusion 304, while the other side is located on the plane of the sliding part. The L-shaped slits 314 are used for the output terminals to pass through and be exposed.

[0055] Please see Figure 9 and Figure 10 In some embodiments, the sliding portion 301 has multiple first protruding ribs 303 on the side facing the first housing 110. The first protruding ribs 303 cooperate with the first groove 302, allowing the first protruding ribs 303 to slide within the first groove 302. In this embodiment, the sliding portion 301 has two parallel first protruding ribs 303 of equal length. The first protruding ribs 303 cooperate with the first groove 302, allowing the first protruding ribs 303 to slide within the first groove 302.

[0056] Please see Figure 6 , Figures 8 to 11 In some embodiments, the fixing part 307 is provided with at least one second through hole 308. The second through hole 308 is elongated and extends along the sliding direction of the sliding part 301. In this embodiment, the fixing part 307 is provided with, for example, two second through holes 308. The two second through holes 308 are respectively located on both sides of the opening 115 and correspond to the position of the sliding post 309. The sliding post 309 can pass through the corresponding second through hole 308 and can move along the extending direction of the second through hole 308, so that the sliding part 301 can slide between a first position and a second position. Specifically, when the sliding post 309 is located at the end of the second through hole 308 away from the output part 205, it indicates that the sliding part 301 is in the first position relative to the fixing part 307. When the sliding post 309 is located at the end of the second through hole 308 close to the output part 205, it indicates that the sliding part 301 is in the second position relative to the fixing part 307.

[0057] Please see Figures 8 to 9In some embodiments, the plane containing the second through hole 308 protrudes beyond the plane containing the fixing part 307, and the plane containing the second through hole 308 is located on the side of the fixing part 307 away from the sliding part 301.

[0058] Please see Figure 6 and Figure 8 In some embodiments, the fixing part 307 is provided with a plurality of fixing members 315 on the side away from the sliding part 301, and the fixing members 315 are located between the output part 205 and the second through hole 308. In this embodiment, the fixing part 307 is provided with two T-shaped fixing members 315, and each T-shaped fixing member 315 is correspondingly disposed between a second through hole 308 and the output part 205.

[0059] Please see Figure 5 , Figure 6 and Figure 8 In some embodiments, an elastic element 310 is provided between the sliding part 301 and the fixed part 307. The elastic element 310 can be, for example, a spring or other element that can perform stretching and compression functions. Specifically, in this embodiment, one end of the elastic element 310 is sleeved on the fixed part 315, and the other end of the elastic element 310 abuts against the sliding column 309.

[0060] Please see Figure 8 In some embodiments, the sliding part 301 is provided with a plurality of second ribs 312 on the side opposite to the sliding protrusion 304. In this embodiment, the sliding part 301 is provided with, for example, two second ribs 312, which are parallel to each other and are arranged on both sides of the sliding column 309.

[0061] Please participate Figure 4 , Figure 6 , Figure 8 and Figure 9 In some embodiments, the fixing part 307 has multiple second grooves 311 on one side adjacent to the sliding part 301. The second grooves 311 extend along the sliding direction of the sliding part 301, and the second ribs 312 cooperate with the second grooves 311, allowing the second ribs 312 to slide within the second grooves 311. In this embodiment, the fixing part 307 has, for example, two second grooves 311 that are broken in the middle. In other embodiments, the number of second grooves 311 and second ribs 312 can also be other values.

[0062] Please see Figures 1 to 11In use, the battery pack 3 is slid into the recess 320 from the guide rail 116 by external force, and contacts the sliding protrusion 304 covering the output part 205. During the process of pressing down the sliding protrusion 304, the battery pack 3 drives the sliding column 309 to slide in the direction of the output part 205 within the second through hole 308. The sliding part 301 slides relative to the first housing and the fixed part 307 through the cooperation between the first groove 302 and the first rib 303 and the second groove 311 and the second rib 312, so that the elastic member 310 changes from the initial state to the compressed state. At this time, the sliding part 301 moves from the first position to the second position relative to the fixed part 307. When the sliding part 301 moves to the second position, the output part 205 exposes the sliding protrusion 304. During the process of the battery pack 3 being disengaged from the recess 320 by the guide rail 116 by external force, the elastic member 310 gradually recovers from the compressed state to the initial state, causing the sliding column 309 to slide in the second through hole 308 in a direction away from the output part 205. The sliding part 301 slides relative to the first housing 110 and the fixed part 307 through the cooperation between the first groove 302 and the first rib 303 and the second groove 311 and the second rib 312, until the sliding part 301 moves from the second position to the first position. When the sliding part 301 moves to the first position, the sliding protrusion 304 covers the output part 205.
