In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0047] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0048] See also Figures 1 to 11 As shown, in one or more embodiments, the present application provides a charger 100, which includes: a shell 103, a first electrical connector 101 and a second electrical connector 102; the shell 103 has at least one battery slot 104, and the battery slot 104 is used for inserting a rechargeable battery; the shell 103 also has a first docking portion 105 and a second docking portion 106, the first electrical connector 101 is located at the first docking portion 105, and the second electrical connector 102 is located at the second docking portion 106; the first docking portion 105 is used to be detachably connected to the second docking portion 106 of another charger 100, so that the first electrical connector 101 is electrically connected to the second electrical connector 102 of another charger 100.

[0049] The present application forms a charging combination by electrically connecting two or more chargers 100, so that a charging line can be used to power the charging combination, and the rechargeable battery on each charger 100 can be charged, thereby saving charging lines, simplifying the line of the studio, and ensuring the cleanliness and safety of the studio. The splicing arrangement of multiple chargers 100 also solves the problem of waiting time for charging several rechargeable batteries and the problem of multiple charging connectors and wires, so that limited space can be reasonably used.

[0050] See also Figures 1 to 3 As shown, in some embodiments, the base of the shell 103 is in the shape of a rectangular parallelepiped; the first electrical connector 101 and the second electrical connector 102 can both be called electrical connectors, the first electrical connector includes a plurality of spaced pins 107, and the pins 107 are connected to a spring; and the second electrical connector 102 includes a plurality of spaced contact sheets 108; when the pins 107 abut against the contact sheets 108, the spring is compressed to realize the connection between the two chargers 100; the pins 107 can be a columnar or spherical structure.

[0051] See also Figures 1 to 3As shown, in some embodiments, the housing 103 may have a plurality of battery slots 104, so that the rechargeable battery can be in contact with the electrode 149 in the battery slot 104 to achieve electrical connection between the rechargeable battery and the electrode; illustratively, the number of battery slots 104 may be two; it is understandable that the number of battery slots 104 may also be 3, 4 or 5, etc. The first docking portion 105 and the second docking portion 106 are arranged opposite to each other, so that when two or more chargers 100 are connected and spliced ​​together, a straight line structure can be formed; since the charger 100 has the first docking portion 105 and the second docking portion 106, each charger 100 can be detachably fixedly connected with one or two chargers 100, thereby realizing the series connection of multiple chargers 100, but the chargers 100 are connected in parallel in the circuit, so that each charger 100 can meet the voltage requirements.

[0052] It should be noted that the connection between the first docking portion 105 and the second docking portion 106 mentioned in the embodiment of the present application refers to the connection between two chargers 100, rather than the docking between the first docking portion 105 of the same charger 100 and its own second docking portion 106. In addition, in some other possible implementations, the installation positions of the first electrical connector 101 and the second electrical connector 102 can be swapped, that is, the first electrical connector 101 is located at the second docking portion 106, and the second electrical connector 102 is located at the first docking portion 105; or, the first electrical connector 101 includes a plurality of spaced contact pieces 108, and the second electrical connector 102 includes a plurality of spaced pins 107.

[0053] See 1 to Figure 4 As shown, in some embodiments, the housing 103 includes a main housing 109 and a battery housing 110; the main housing 109 has a first through hole 111, and the battery housing 110 is fixed in the first through hole 111; in this way, the manufacture of the charger 100 is convenient through assembly. The battery slot 104 is located on the battery housing 110; the cross section of the main housing 109 is annular, and the cross section of the main housing 109 is perpendicular to the length direction of the main housing 109, so that the two opposite ends of the main housing 109 are open; the housing 103 also includes a first side cover and a second side cover; the first side cover and the second side cover are respectively fixedly connected to the main housing 109 by screws; the battery housing 110 and the main housing 103 are fixedly connected by screws; the first side cover forms a first docking portion 105, and the second side cover forms a second docking portion 106. The depth of the battery slot 104 matches the rechargeable battery, which can prevent the battery from falling off due to shaking during charging; for example, the depth of the battery slot 104 can be half or one-third of the length of the rechargeable battery.

[0054] See also Figures 1 to 3As shown, in some embodiments, the main shell 109 has a top surface 112 and a bottom surface 113 relative to each other, and two side surfaces 114 relative to each other, and the first through hole 111 is located on the top surface 112 of the main shell 109, so that the rechargeable battery can be vertically inserted into the battery slot 104 of the battery shell 110. The bottom surface 113 of the main shell 109 has an air inlet 115, and the air inlet 115 can include a plurality of long strip-shaped through holes or circular through holes. One side surface 114 of the main shell 109 has an air outlet 116, and the air outlet 116 can include a plurality of long strip-shaped through holes or circular through holes. Of course, the shape of the through hole can also be designed into other shapes. By designing the air outlet 116 and the air inlet 115, the heat dissipation of the charger 100 is facilitated.

[0055] See also Figure 5 As shown, in some embodiments, the charger 100 further includes a circuit board 117, on which a transformer, a rectifier and a control chip are generally integrated to realize charging of the rechargeable battery; wherein the transformer is used to convert the power input voltage into a voltage level suitable for charging the device and provide an isolated and stable output current. The rectifier converts the AC power into a DC power for charging the device. The control chip is used to monitor and control the operation of the charger 100 circuit to ensure safe and efficient charging. The circuit board 117 is also integrated with a plurality of LED lights, so that the number of LED lights that light up indicates whether the rechargeable battery is fully charged; the circuit board 117 is also integrated with a button switch 148, which is used to control the turning on or off of all LED lights. In this way, in order to avoid interference from LED lights at night, the LED lights can be turned off by the button switch 148, and the button switch 148 is also used to control whether the charging status is displayed by lighting up the LED lights; the circuit board 117 is also integrated with a USB interface 119 and a TYPE-C interface 118 as power input ports, which are connected to a charging line through the TYPE-C interface 118 to charge the rechargeable battery in the battery slot 104; and the USB interface 119 can be connected to a charging line, so that when the rechargeable battery is fully charged, the rechargeable battery inserted in the battery slot 104 can be used to charge other electronic devices. The number of TYPE-C interfaces 118 can be two or more; the electrode 149 is integrated on the circuit board 117.

[0056] It should be noted that the connection relationship between the integrated components of the circuit board 117, the control of the components on the circuit board 117, the charging of the rechargeable battery, and the charging of other electronic devices by the rechargeable battery inserted in the charger 100, and the realization of bidirectional charging should be understood by those skilled in the art, and are well known and easy to implement for those skilled in the art, so the embodiments of the present application will not be described in detail. In addition, in some other possible implementations, the TYPE-C interface 118 can also be set to support a bidirectional charging mode, that is, the rechargeable battery in the battery slot 104 can be charged through the charging cable, and when the rechargeable battery is fully charged, the rechargeable battery inserted in the battery slot 104 can be used to charge other electronic devices through the TYPE-C interface 118.

[0057] See also Figure 5 As shown, in some embodiments, the TYPE-C interface 118 corresponds to the first jack 121 of a side surface 114 of the main shell 109; the USB interface 119 corresponds to the second jack 122 of the top surface 112 of the main shell 109. The button switch 148 extends out of the second through hole 120 of the top surface 112 of the main shell 109, which is convenient for operating the button switch 148; and a light guide column 124 corresponds between each LED lamp; the top of the light guide column 124 corresponds to the third through hole 123 of the top surface 112 of the main shell 109, which is convenient for observing the light emitted by the LED lamp from the outside of the shell 103 through the light guide column 124. Two adjacent LED lamps are separated by a light isolation structure 125, so as to avoid light crosstalk between multiple LED lamps. The light isolation structure 125 can be a part of the main shell 103 or a split structure. The light isolation structure 125 is fixed to the circuit board 117 or bonded to the main shell by screws. The light isolation structure 125 has a plurality of light holes, and the plurality of LED lights are arranged in one-to-one correspondence with the plurality of light holes, and the light guide column 124 can be inserted into the light holes; the light guide column 124 can be made of transparent plastic, such as PC or PMMA.

[0058] In the process of splicing two chargers 100, when one charger 100 is already connected to an external power source, and then another charger 100 is connected to the charger 100 already connected to the external power source, the electrical connection between the first electrical connector 101 and the second electrical connector 102 between the two chargers 100 may generate electric sparks. In order to solve this problem, the charger 100 in the embodiment of the present application is also provided with a switch assembly. Figure 6 , Figure 7 and Figure 8As shown, in some embodiments, the charger 100 further includes a switch assembly, the switch assembly is electrically connected to the circuit board 117, the first electrical connector 101 and the second electrical connector 102 are electrically connected to the circuit board 117 respectively; the switch assembly is arranged at the first docking portion 105; the switch assembly is configured to be triggered during the docking process between the first docking portion 105 and the second docking portion 106 of another charger 100, so as to disconnect the charger 100 from the other charger 100, thereby avoiding the phenomenon of electric sparks during the splicing process.

[0059] In some embodiments, the switch assembly includes an elastic trigger portion and a push switch 126, the elastic trigger portion is mounted on the housing 103, and the push switch 126 is electrically connected to the circuit board 117; the elastic trigger portion includes an elastic member 127 and a push button 128, and the push button 128 is used to press the push switch 126 by compressing the elastic member 127.

[0060] In one embodiment, it is a normally closed self-resetting key switch. The normally closed self-resetting key switch is a type in which: the contact is in a closed state when not pressed, and the contact is disconnected when the button is pressed, cutting off the current; after releasing the button, the contact automatically returns to the original closed state and restores the power-on state. By using the key switch 126, the charger 100 where the switch assembly is located is in an open circuit state when pressed. The elastic member 127 is a spring; and the push button 128 is a block structure, such as a rectangular parallelepiped; the push button 128 also has a toggle portion 129, which is convenient for the user to toggle by hand, and the other side 114 of the main shell 109 has a corresponding toggle through hole, and the toggle portion 129 extends into the toggle through hole so that the toggle portion 129 is exposed; the toggle through hole can be a rectangular through hole. The push button 128 has a front end surface 143 and a rear end surface 144 opposite to each other. Two insertion posts 130 are fixed to the front end surface 143 of the push button 128 . The two insertion posts 130 are respectively sleeved with elastic members 127 .

[0061] It should be noted that although the switch assembly provided in the embodiment of the present application can solve the problem of electric sparks generated during the splicing of two chargers 100; however, in order to ensure safety in use as much as possible, when multiple chargers 100 are connected to each other, it is recommended that the chargers 100 be connected when they are not connected to an external power source or socket. Of course, the above usage suggestions are not limitations on the structure of the charger 100 in the embodiment of the present application and the corresponding problems to be solved. In some other possible implementations, the switch assembly can be provided at the second docking portion 106, or the switch assembly can be provided at both the first docking portion 105 and the second docking portion 106 of the charger 100.

[0062] See also Figure 7As shown, in some embodiments, the switch assembly further includes a guide member 131, the guide member 131 has a first guide groove 132, and the push button 128 is slidably disposed in the first guide groove 132; one end of the elastic member 127 abuts against the push button 128, and the other end of the elastic member 127 abuts against the guide member 131, so that when the elastic member 127 is compressed, the front end surface 143 of the push button 128 can contact the key switch 126; through the first guide groove 132, the push button 128 is slidable in a preset direction, that is, moves in the axial direction of the plug-in column 130. In one embodiment, the switch assembly further includes a push button cover 147, and the push button cover 147 is fixedly connected to the guide member 131 by screws, so that the push button 128 is limited on the guide member 131.

[0063] See also Figures 1 to 3 , and combined Figures 9 to 11 As shown, in some embodiments, one of the first docking portion 105 and the second docking portion 106 has a guide slider 133, and the other has a guide slot 134; when the first docking portion 105 docks with the second docking portion 106 of another charger 100, the guide slider 133 can move along the length direction of the guide slot 134 to be limited in the guide slot 134; this facilitates the connection between the two chargers 100 by sliding fit, that is, wireless connection, that is, connection is achieved by non-wired means. In one embodiment, the guide slot 134 is provided on the first docking portion 105, and the guide slider 133 is provided on the second docking portion 106; the length direction of the guide slot 134 is parallel to the direction of the main shell 109 from one side 114 to the other side 114; and the movement direction of the push button 128 is parallel to the direction from the first docking portion 105 to the second docking portion 106.

[0064] It is understandable that the first electrical connector 101 and the second electrical connector 102 are not limited to the above-mentioned matching mode, but can also be in other forms, such as plug-in form; and when the first electrical connector 101 and the second electrical connector 102 are plug-in matched, the first docking portion 105 and the second docking portion 106 can be plug-in matched. In addition, the guide slide groove 134 can also be provided on the second docking portion 106, and the guide slider 133 is provided on the first docking portion 105.

[0065] See also Figure 8As shown, in some embodiments, the guide slider 133 includes a base portion 135 and a limiting wing 136, the limiting wing 136 is connected to the base portion 135, and the width of the limiting wing 136 is greater than the width of the base portion 135; the guide slide 134 includes a limiting groove 137 and a sliding groove 138 connected to the limiting groove 137, and the width of the limiting groove 137 is greater than the width of the sliding groove 138; the limiting wing 136 extends into the limiting groove 137, and at least part of the base portion 135 is located in the sliding groove 138; this facilitates the limiting of the guide slider 133. In one embodiment, the width direction of the base portion 135 is parallel to the direction of the main shell 109 from the top surface 112 to the bottom surface 113; the width direction of the base portion 135 is parallel to the width direction of the limiting groove 137; the width direction of the limiting wing 136 is parallel.

[0066] See also Figure 5 As shown, in some embodiments, the two ends of the guide slot 134 in the length direction are an open end 139 and a closed end 140 respectively; the two ends of the guide slider 133 in the length direction are a first end 141 and a second end 142 respectively, and the first end 141 has a guide slope 146; when the first docking portion 105 docks with the second docking portion 106 of another charger 100, the first end 141 slides from the open end 139 into the guide slot 134, which helps to ensure the stability of the connection between the two chargers 100. The length of the guide slot 134 is greater than the length of the guide slider 133.

[0067] Combination Fig. 9 , Fig.10 and Fig.11 As shown, Fig.10This is also a state diagram after the two chargers are docked; in some embodiments, the switch assembly is also used to limit the movement of the guide slider 133 along the length direction of the guide slot 134, so that the guide slider 133 is locked in the guide slot 134, thus ensuring the stability of the connection between the two chargers 100. Exemplarily, the second end 142 of the push button 128 extends into the guide slot 134, and the distance between the second end 142 of the push button 128 and the closed end 140 of the guide slot 134 is greater than or equal to the length of the guide slider 133. The rear end face 144 of the push button 128 has an inclined surface 145, and the inclined surface 145 cooperates with the guiding inclined surface 146; when the two chargers 100 are connected, the guiding inclined surface 146 on the guiding slider 133 contacts the inclined surface 145 of the push button 128, so that the push button 128 moves in the direction where the key switch 126 is located to trigger the key switch 126; when the guiding slider 133 completely enters the guiding groove 134, since the length of the guiding groove 134 is greater than the length of the guiding slider 133, and the second end 142 of the push button The distance between the closed end 140 of the guide slot 134 is greater than or equal to the length of the guide slider 133, so that the push button 128 is no longer squeezed by the guide slider 133, and the push button 128 is reset under the action of the elastic member 127, and can abut against the end surface of the second end 142 of the guide slider 133, so that the guide slider 133 is locked in the guide slot 134; and when the push button 128 is reset, the push button 128 is no longer abutted against the key switch 126, and the key switch 126 makes the charger 100 become the access state again. In addition, when the two chargers 100 need to be disassembled, the disassembly can be achieved by only moving the toggle part 129.
