The old input interface provided on the old power tool is matched with the single-voltage output interface provided on the single-voltage battery pack and capable of outputting only one voltage, the single-voltage output interface being unmatched with the new input interface, thereby causing the single-voltage battery pack in the user's hand to be in an idle state, thereby causing resource waste.

[0025] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is described in detail below in combination with the drawings and specific embodiments.

[0026] Different electric tools usually have different rated working voltages, for example: handheld blower, handheld drill, handheld sander, etc. Manufacturers need to configure corresponding single pressure battery packs for each type of electric tool. Such single pressure battery packs only have one output voltage, so that such single pressure battery packs can only be matched with a single electric tool, and cannot be matched with multiple electric tools. Therefore, researchers have redesigned a battery pack with a multi-voltage output interface and a new input interface provided on a new electric tool and matched with the multi-voltage output interface. The multi-voltage output interface has at least two coupling states to output different voltages in different coupling states, thereby achieving the purpose of matching multiple new electric tools with one multi-voltage battery pack. However, the single pressure output interface provided on the single pressure battery pack already in the hands of the user does not match the new input interface provided on the new electric tool, so that the single pressure battery pack in the hands of the user is in an idle state, thereby causing resource waste.

[0027] Referring to Figure 1 and Figure 2 , the present application discloses an adapter 100 to solve the problem that the single pressure output interface on the single pressure battery pack in the hands of the user cannot match the new input interface provided on the new electric tool, thereby avoiding the single pressure battery pack in the hands of the user being in an idle state, and thereby improving the utilization rate of the single pressure battery pack. The adapter 100 comprises a housing 10, an input port 20, an output port 30 electrically connected to the input port 20, and a clamping mechanism 40.

[0028] Referring to Figure 3 , Figure 4 and Figure 5As shown, the housing 10 comprises a top wall 11, a bottom wall 12 opposite to the top wall 11, a front wall 13 close to the output port 30, a rear wall 14 close to the holding mechanism 40, and side walls 15 on both sides of the top wall 11. The top wall 11, the bottom wall 12, the front wall 13, the rear wall 14, and the side walls 15 jointly define a receiving cavity (not shown) for receiving the input port 20, the output port 30, and the holding mechanism 40. The top wall 11 is provided with a terminal receiving groove 111 at an end close to the front wall 13, and the terminal receiving groove 111 is in communication with the receiving cavity. The top wall 11 is provided with a holding groove 112 in communication with the receiving cavity at an end close to the rear wall 14. The front wall 13 and the bottom wall 12 are provided with an input terminal groove 131 in communication with the receiving cavity. The rear wall 14 is provided with a pressing groove 141 in communication with the receiving cavity. The bottom wall 12 and the side walls 15 jointly define a plug-in portion 151 for sliding insertion of a single-pressure output interface provided on a single-pressure battery pack. In the embodiment, the plug-in portion 151 is an open receiving groove. The side wall 15 is provided with a slide rail 152 on a side facing the plug-in portion 151 for guiding sliding insertion of the single-pressure battery pack. In the embodiment, the slide rail 152 is a groove. However, it can be understood that the slide rail 152 can also be a protrusion, and the present application does not limit the specific structure of the slide rail 152.

[0029] The input port 20 is coupled to a single-pressure output interface provided on an old single-pressure battery pack to obtain a unique output voltage output by the single-pressure battery pack, and the single-pressure output interface is not matched with a new input interface provided on a new power tool. Please refer to Figure 2 and Figure 5 As shown, the input port 20 is installed in the input terminal groove 131 and is used to be coupled to Figure 8 a single-pressure battery pack 50 as shown. The single-pressure battery pack 50 is provided with a single-pressure output interface 51. The single-pressure output interface 51 has only one coupling state, so that only a unique output voltage can be output. Please refer to Figure 6 As shown, the input port 20 comprises a base body 21 and an input terminal set 22 installed on the base body 21. The input terminal set 22 comprises a first input terminal 221, a second input terminal 222, a third input terminal 223, and a fourth input terminal 224, and the second input terminal 222 and the third input terminal 223 are located between the first input terminal 221 and the fourth input terminal 224.

[0030] The output port 30 is electrically connected to the input port 20 to obtain voltage. The output port 30 is coupled to a new input interface provided on a new power tool to output the output voltage to the new power tool. The new input interface is matched with a multi-voltage output interface provided on a multi-voltage battery pack, which has at least two coupling states to output different voltages in different coupling states. It is understood that there are various specific structures for the multi-voltage output interface provided on the multi-voltage battery pack and the new input interface matched therewith. For example, Chinese Patent Application No. 201780067581.2 discloses various multi-voltage output interfaces and their matching input interfaces. The present invention aims to connect the single-voltage output interface provided on an old single-voltage battery pack to a new input interface provided on a new power tool and matched with a multi-voltage battery pack. Therefore, the output port 30 only needs to be matched with the new input interface. As for the specific structure of the output port 30, the present invention does not impose specific limitations. Figure 6 The output port 30 shown is one of many embodiments of the present invention, used to connect with... Figure 9 The new power tool 60 shown is used in conjunction with this new power tool 60. The new power tool 60 is provided with a new input interface (not shown) that matches a multi-voltage output interface disposed on a multi-voltage battery pack. The multi-voltage output interface has multiple coupling states to output different voltages in different coupling states. The output port 30 includes a base 31 and an output terminal group 32 mounted on the base 31 and located within the terminal receiving slot 111. The output terminal group 32 includes a first output terminal 321, a second output terminal 322, a third output terminal 333, and a fourth output terminal 334, with the second output terminal 332 and the third output terminal 333 located between the first output terminal 331 and the fourth output terminal 334. The first input terminal 221 is electrically connected to the first output terminal 321, and the fourth input terminal 224 is electrically connected to the fourth output terminal 324, so that the output port 30 receives an output voltage.

[0031] Please see Figure 7As shown, the clamping mechanism 40 comprises a main body 41 and an elastic element 42 cooperating with the main body 41. One end of the main body 41 is provided with a clamping arm 411, and the other end is provided with a pressing arm 412. The clamping arm 411 is partially accommodated in the accommodating cavity and partially protrudes out of the accommodating cavity from the clamping groove 113. The side of the clamping arm 411 facing the output port 30 is provided with an inclined guide wall 4111. The pressing arm 412 at least partially protrudes out of the accommodating cavity through the pressing groove 141. One end of the elastic element 42 is fixedly installed on the main body 41, and the other end is installed on the shell 10. When the pressing arm 412 is pressed, the clamping arm 411 is driven by the pressing arm 412 to move from the clamping groove 113 into the accommodating cavity, and at this time, the elastic element 42 is in an elastically deformed state. When the pressing arm 412 is released, the pressing arm 412 or the clamping arm 411 is reset under the action of the elastic element 42. In this embodiment, the elastic element 42 is a spring, but in other embodiments, the elastic element 42 can also be an elastic plastic, an elastic sheet, etc.

[0032] As shown in Figure 1 、 Figure 2 、 Figure 7 and Figure 9 When using the adapter 100 of the present application, first, the pressing arm 412 is pressed, at this time, the clamping arm 411 enters the accommodating cavity, then the new input interface of the new power tool 60 is docked with the output port 30, and then the pressing arm 412 is released, at this time, the clamping arm 411 is reset under the action of the elastic element 42, and cooperates with the clamping structure provided on the new power tool 60 to fix the adapter 100 on the new power tool 60. Then, the single-pressure output interface on the single-pressure battery pack 50 is docked with the input port 20. In fact, during use, when the adapter 100 is slidably inserted into the new power tool 60, the guide wall 4111 will cooperate with the corresponding shell on the new power tool 60 and slowly enter the accommodating cavity under the action of the corresponding shell, that is, when the adapter 100 is slidably inserted into the new power tool 60, the user does not need to press the pressing arm 412.

[0033] The present application also discloses a power tool system, comprising a power tool provided with an input interface, a single-pressure battery pack provided with a single-pressure output interface, and the adapter 100; the input interface matches the multi-pressure output interface provided on the multi-pressure battery pack, and the multi-pressure output interface has at least two coupling states to output different voltages in different coupling states; the single-pressure output interface provided on the single-pressure battery pack does not match the input interface.

[0034] Compared with the prior art, the adapter 100 can connect the single-voltage output interface on the single-voltage battery pack with the new input interface arranged on the new power tool and matched with the multi-voltage output interface, so that the new power tool can also use the old single-voltage battery pack, thereby improving the utilization rate of the old single-voltage battery pack.

[0035] The above examples are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.
