[0043] The embodiments of the present invention are described in detail below with reference to the accompanying drawings:

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0045] Please refer to Figures 1 to 6 One embodiment provides a charging device, including a housing and a charging assembly. The housing is formed with an inner cavity, and during charging, the battery pack is engaged with the housing, and the charging assembly is arranged in the inner cavity of the housing to provide electrical energy during charging.

[0046] In one embodiment, please refer to Figures 1 to 6 The housing is provided with a first mating portion and a second mating portion, the first mating portion is used to mate with the first battery pack 410, and the second mating portion is used to mate with the second battery pack 420; an extension plane of the first mating portion and an extension plane of the second mating portion are arranged at an acute angle.

[0047] Please refer again Figures 1 to 6 The charging component includes a circuit board 510, a first electrode seat 521 and a second electrode seat 522. The circuit board 510 is arranged in the inner cavity. The first electrode seat 521 and the second electrode seat 522 are both electrically connected to the circuit board 510. The first electrode seat 521 is correspondingly arranged to the first matching portion for docking with the first battery pack 410. The second electrode seat 522 is correspondingly arranged to the second matching portion for docking with the second battery pack 420.

[0048] like Figure 1 and Figure 6 In the embodiment shown, the upper part of the first mating portion and the upper part of the second mating portion are both inclined toward the middle. Since the extension plane of the first mating portion and the extension plane of the second mating portion are arranged at an acute angle, at least one of the extension planes of the first mating portion and the second mating portion is inclined. Compared with the horizontal arrangement, the inclined arrangement can reduce the occupied space. Compared with the longitudinal arrangement, when the battery pack is matched with the inclined extension plane, the center of gravity of the battery pack is biased toward the inner side of the charging device, thereby avoiding the occurrence of tipping.

[0049] In one embodiment, please refer to Figure 1 In order to solve the assembly problem of the battery pack and the charging device during charging, the housing includes a bottom housing 213, a first housing 211 and a second housing 212 that are interconnected to form an inner cavity.

[0050] The first matching portion has a first sliding groove 2111 / first sliding rail opened on the first shell 211 , and the first battery pack 410 is slidingly matched with the first shell 211 through the first sliding groove 2111 / first sliding rail.

[0051] The second matching portion has a second sliding groove 2121 / a second sliding rail provided on the second shell 212 , and the second battery pack 420 is slidingly matched with the second shell 212 via the second sliding groove 2121 / the second sliding rail.

[0052] With such arrangement, the first battery pack 410 and the second battery pack 420 cooperate with the charging device by sliding, making the charging operation more convenient.

[0053] In one embodiment, the first mating portion has a first opening 2112 opened on the first shell 211, the second mating portion has a second opening 2122 opened on the second shell 212, the housing is also provided with a first air outlet 201, and the charging device also includes a heat dissipation component, and the heat dissipation component includes a first fan 310 located in the inner cavity.

[0054] Please refer to Figure 6 When the first battery pack 410 cooperates with the first matching portion and the second battery pack 420 cooperates with the second matching portion, the first fan 310 can generate a first airflow 610 and a second airflow 620. The first airflow 610 flows through the first battery pack 410 and then flows to the first fan 310 from the first opening 2112. The second airflow 620 flows through the second battery pack 420 and then flows to the first fan 310 from the second opening 2122. The first airflow 610 and the second airflow 620 converge through the first fan 310 and then are discharged from the first air outlet 201.

[0055] This configuration is to solve the problem of how to achieve heat dissipation of the first battery pack 410 and the second battery pack 420. When the first battery pack 410 and the second battery pack 420 are both placed on the casing, the first fan 310 starts and generates a first airflow 610 and a second airflow 620, thereby achieving heat dissipation of the first battery pack 410 and the second battery pack 420.

[0056] It should be noted that:

[0057] The battery pack has a front and a back, the front refers to the side facing the housing after being matched with the housing, and the back is the side opposite to the front. The front of the battery pack is provided with a battery air outlet 412, and the back of the battery pack is provided with a battery air inlet 411, and the battery air inlet 411 and the battery air outlet 412 are connected. When the battery pack is charging, the corresponding airflow can enter through the battery air inlet 411, and further flow to the battery air outlet 412, and then further converge through the first fan 310 and flow out to achieve heat dissipation of the battery pack.

[0058] For details, please refer to Figure 6 and Fig.10 , taking the first battery pack 410 as an example for explanation:

[0059] The first battery pack 410 has a front side and a back side. Fig.10 The front side of the first battery pack 410 is located at the lower side of the first battery pack 410, and the back side is located at the upper side of the first battery pack 410. When the first battery pack 410 is mated with the first mating portion, the front side faces one side of the first mating portion, and the back side is located on the outside. When the first fan 310 is started, the airflow can enter through the battery air inlet 411 on the back, and finally enter the inner cavity of the housing through the battery air outlet 412 on the front, and converge at the first fan 310.

[0060] Fig.10 The middle mark shows the battery air inlet direction 413 and the battery air outlet direction 414 of the first battery pack 410. It can be seen that the air flow enters from the battery air inlet 411 and is finally discharged from the battery air outlet 412 to enter the inner cavity through the first opening 2112, which will not be repeated.

[0061] In one embodiment, please refer to Figures 1 to 7 The heat dissipation component also includes a first pipe 221 and a second pipe 222, one end of the first pipe 221 is connected to the first opening 2112, one end of the second pipe 222 is connected to the second opening 2122, the other end of the first pipe 221 is connected to the other end of the second pipe 222 to form a connecting port 240, and the connecting port 240 is connected to the first fan 310.

[0062] During operation, the first airflow 610 enters the first pipe 221 from the first opening 2112 and arrives at the connecting port 240, and the second airflow 620 enters the second pipe 222 from the second opening 2122 and arrives at the connecting port 240. The first airflow 610 and the second airflow 620 converge at the connecting port 240 and arrive at the first fan 310.

[0063] This solution solves the problem of how to achieve heat dissipation and cooling of the first battery pack 410 and the second battery pack 420 (i.e., two battery packs) by a first fan 310. Through the first pipe 221 and the second pipe 222, when the first fan 310 is started, a negative pressure environment is formed in the first pipe 221 and the second pipe 222, thereby further forming a first airflow 610 and a second airflow 620, thereby achieving heat dissipation for the first battery pack 410 and the second battery pack 420.

[0064] like Figure 7 and Figure 8 The embodiment shown, wherein Figure 8 2 is a schematic diagram of the structure of the first pipe 221. A first mounting portion 2211 is provided on the lower side of the first pipe 221 facing the second pipe 222. The first mounting portion 2211 is a semicircular groove. Figure 7 As shown, a second mounting portion 2221 is provided at the lower side of the second pipe 222 facing the first pipe 221. The second mounting portion 2221 is also a semicircular trough body corresponding to the first mounting portion 2211. The two semicircular trough bodies are connected to form a circular trough body mounting structure. The circular trough body mounting structure corresponds to and communicates with the connecting port 240. The first fan 310 is a circular structure and is installed between the first pipe 221 and the second pipe 222 through the circular trough body mounting structure, so that the first airflow 610 and the second airflow 620 converge at the first fan 310 after passing through the connecting port 240.

[0065] In one embodiment, please refer to Figure 1 and Fig. 9 The heat dissipation assembly further includes a first baffle 231 and a second baffle 232 , and both the first baffle 231 and the second baffle 232 are capable of being reset.

[0066] The first baffle 231 is rotatably engaged with the first shell 211, and a first pressing block 2311 is provided on the first baffle 231; when the first battery pack 410 is not engaged with the first mating portion, the first baffle 231 covers the first opening 2112, and when the first battery pack 410 is engaged with the first mating portion, the first battery pack 410 presses against the first pressing block 2311, so that the first pressing block 2311 drives the first baffle 231 to rotate toward the inner side of the inner cavity to open the first opening 2112.

[0067] The second baffle plate 232 is rotatably matched with the second shell body 212, and a second pressing block 2321 is provided on the second baffle plate 232; when the second battery pack 420 is not matched with the second matching portion, the second baffle plate 232 covers the second opening 2122, and when the second battery pack 420 is matched with the second matching portion, the second battery pack 420 presses against the second pressing block 2321, so that the second pressing block 2321 drives the second baffle plate 232 to rotate toward the inner side of the inner cavity to open the second opening 2122.

[0068] This solution ensures that when only one battery pack (the first battery pack 410 or the second battery pack 420) is charged, the first fan 310 only dissipates heat for the battery pack and only acts on the corresponding pipe (the first pipe 221 or the second pipe 222), so that the cooling airflow cools the battery pack in use to the greatest extent. Specifically:

[0069] When the first battery pack 410 is engaged with the first mating portion and the second battery pack 420 is not engaged with the second mating portion, the first battery pack 410 presses against the first pressing block 2311, thereby causing the first baffle 231 to rotate toward the inside of the inner cavity to open the first opening 2112. At this time, the first fan 310 is started, and a first airflow 610 is formed in the first pipe 221. The first airflow 610 only performs heat dissipation on the first battery pack 410.

[0070] In this case, the first baffle 231 rotates inward under the pressure, thereby opening the first opening 2112, and the second baffle 232 is not pressed, so the second opening 2122 remains closed. Therefore, only the first airflow 610 is generated, which only serves to dissipate heat for the first battery pack 410.

[0071] When the second battery pack 420 is engaged through the second mating portion and the first battery pack 410 is not engaged with the first mating portion, the second battery pack 420 presses against the second pressing block 2321, so that the second baffle 232 rotates toward the inside of the inner cavity to open the second opening 2122. At this time, the first fan 310 is started, and a second airflow 620 is formed in the second pipe 222. The second airflow 620 only performs heat dissipation on the second battery pack 420.

[0072] In this case, the second baffle 232 rotates inward under the pressure, thereby opening the second opening 2122, and the first baffle 231 is not pressed, so the first opening 2112 remains closed. Therefore, only the second airflow 620 is generated, which only serves to dissipate heat for the second battery pack 420.

[0073] When the first battery pack 410 is engaged through the first mating part and the second battery pack 420 is engaged through the second mating part, the first baffle 231 and the second baffle 232 are both opened. At this time, the first fan 310 is started, and a first airflow 610 is formed in the first pipe 221, and a second airflow 620 is formed in the second pipe 222. The first airflow 610 and the second airflow 620 finally merge into the connecting port 240 and enter the first fan 310, and then are discharged through the first air outlet 201.

[0074] In one embodiment, please refer to Fig. 9 There are two first pressing blocks 2311, which are respectively arranged on the opposite sides of the first baffle 231. The first pipe 221 is provided with a first matching hole, which is provided with two and corresponds to the first pressing blocks 2311 one by one. The first pressing blocks 2311 can extend into or exit the corresponding first matching holes.

[0075] There are two second pressing blocks 2321, which are respectively arranged on the opposite sides of the second baffle 232. The second pipe 222 is provided with a second matching hole. There are two second matching holes and they correspond one to one with the second pressing blocks 2321. The second pressing blocks 2321 can extend into or out of the corresponding second matching holes.

[0076] This solution solves the problem of how to assemble the baffle plate and the pipeline. Through the setting of the matching holes, the pressing block can be extended into and out of the corresponding matching holes.

[0077] In one embodiment, please refer to Figure 1 and Fig. 9 The first baffle plate 231 and the second baffle plate 232 are both located in the inner cavity, and the first baffle plate 231 and the second baffle plate 232 are connected by a spring 233.

[0078] This solution solves the technical problem of how to reset the first baffle 231 and the second baffle 232. By setting the spring 233, the two ends of the spring 233 press against the first baffle 231 and the second baffle 232 respectively, so that the first baffle 231 always covers the first opening 2112 when no external force is applied, and the second baffle 232 always covers the second opening 2122 when no external force is applied.

[0079] When the first baffle 231 is subjected to external force, the spring 233 is compressed, the first baffle 231 retreats and opens the first opening 2112, thereby dissipating heat from the first battery pack 410; or / and when the second baffle 232 is subjected to external force, the spring 233 is compressed, the second baffle 232 retreats and opens the second opening 2122, thereby dissipating heat from the second battery pack 420. After the external force disappears, the first baffle 231 and / or the second baffle 232 automatically resets under the reset action of the spring 233, which is equivalent to achieving the technical effect of automatic locking.

[0080] In one embodiment, please refer to Figures 1 to 6 The housing is provided with a second air inlet 203 and a second air outlet 202, and the second air inlet 203 and the second air outlet 202 are respectively arranged on opposite sides of the housing, and the heat dissipation component also includes a second fan 320 located in the inner cavity, and the second fan 320 can form a third airflow 630, and the third airflow 630 enters from the second air inlet 203, flows through the circuit board 510, and is discharged from the second air outlet 202.

[0081] This solution solves the problem of how to dissipate heat and the air in and out of the circuit board 510. By setting the second fan 320, when the second fan 320 is started, the third airflow 630 enters from the second air inlet 203 and passes through the circuit board 510, and is discharged from the second air outlet 202 on the opposite side of the second air inlet 203, thereby achieving heat dissipation of the circuit board 510.

[0082] In one embodiment, please refer to Figures 1 to 6 The first air outlet 201 and the second air outlet 202 are located on the same side of the housing, and the first air outlet 201 is located above the second air outlet 202 .

[0083] This solution solves the problem of how to arrange the first air outlet 201 and the second air outlet 202 so that the air outlet positions are unified and the flow directions of the first airflow 610, the second airflow 620 and the third airflow 630 in the inner cavity do not conflict. The first air outlet 201 and the second air outlet 202 are arranged on the same side of the housing, thereby avoiding the contradiction between air intake and air outlet.

[0084] In one embodiment, please refer to Figures 1 to 6 The charging device is further provided with a first cover shell 2141 , a second cover shell 2142 and a third cover shell 2143 . The first cover shell 2141 is arranged corresponding to the first air outlet 201 , the second cover shell 2142 is arranged corresponding to the second air inlet 203 , and the third cover shell 2143 is arranged corresponding to the second air outlet 202 .

[0085] Optionally, the first cover 2141 and the second cover 2142 can be provided as separate components separated from the housing (eg, Figure 1 As shown), it can also be configured to be integrally formed with the housing, which is not limited to this.

[0086] Optionally, the first cover shell 2141, the second cover shell 2142 and the third cover shell 2143 are all shutter structures to achieve air inlet and outlet and dust prevention effects.
