Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Different power tools typically have different rated operating voltages, for example: hand-held suction blowers, hand-held electric drills, hand-held sanders, and the like. Manufacturers are required to configure each power tool with a corresponding battery pack. Such battery packs have only one output voltage, so that such battery packs can only be paired with a single power tool, but not with a plurality of power tools. For this purpose, developers have designed a battery pack with a multi-voltage output interface to match a plurality of power tools with different rated voltages. However, the voltage input interface of the old electric tool existing in the hand of the user is matched with the output interface arranged on the old battery pack, and the output interface arranged on the old battery pack can only output one voltage. Therefore, the newly designed multi-pressure output interface is not matched with the existing old electric tool interface in the hand of the user, so that the application range of the battery pack with the multi-pressure output interface is limited.

Referring to fig. 1 and 2, the present invention discloses an adapter 100 for solving the problem that the interfaces of the old electric tools in the hands of the user cannot be matched with the interfaces of the multi-voltage output battery pack, so as to expand the application range of the multi-voltage output battery pack. The adapter 100 includes a housing 10, an input port 20, an output port 30 that mates with the input port 20, and a latching mechanism 40.

Referring to fig. 3, 4 and 5, the housing 10 includes a top wall 11, a bottom wall 12 opposite to the top wall 11, a front wall 13 near the output port 30, a rear wall 14 near the retaining mechanism 40, and side walls 15 at two sides of the top wall 12. The top wall 11, the bottom wall 12, the front wall 13, the rear wall 14, and the side wall 15 together define a receiving cavity (not shown) for receiving the input port 20, the output port 30, and the latching mechanism 40. An output terminal groove 111 and a fool-proof mechanism 112 are provided at an end of the top wall 11 close to the front wall 13. The output terminal groove 111 is communicated with the accommodating cavity, and the fool-proof mechanism 112 is located between the output terminal groove 111 and the front wall 13. The fool-proof mechanism 112 is used to cooperate with an auxiliary mechanism (not shown) disposed on the electric tool to prevent misplug. In the present embodiment, the fool-proof mechanism 112 is disposed on the housing 10, but it is understood that the fool-proof mechanism 112 may also be disposed on the output port 30. In this embodiment, the fool-proof mechanism 112 is a protrusion, and the auxiliary mechanism is a groove matched with the protrusion. However, it should be understood that the specific structure of the fool-proof mechanism 112 has various structures, and the present invention is not repeated herein. One end of the top wall 11 close to the rear wall 14 is provided with a retaining groove 113 communicated with the containing cavity. An input terminal groove 131 communicated with the accommodating cavity is arranged between the front wall 13 and the bottom wall 12. The rear wall 14 is provided with a pressing groove 141 communicating with the housing chamber. The bottom wall 12 and the side wall 15 together form a plug-in slot 151 for slidably inserting a multi-pressure output port disposed on the battery pack. The side wall 15 facing the insertion groove 151 is further provided with a slide rail 152 to guide the battery pack to be inserted slidably. In this embodiment, the sliding rail 152 is a groove. However, it is understood that the sliding rail 152 may be a protrusion, and the present invention is not limited to the specific structure of the sliding rail 152.

The input port 20 is coupled to a multi-voltage output interface provided on the battery pack to obtain an output voltage of the battery pack. The multi-voltage output interface has at least two coupling states; when the multi-voltage output interface is in a first coupling state, the output interface outputs a first voltage; when the multi-voltage output interface is in a second coupling state, the multi-voltage output interface outputs a second voltage different from the first voltage. The input port 20 is provided with a switching mechanism which is matched with the multi-voltage output interface to change the output voltage of the multi-voltage output interface. Fig. 6 illustrates one of many embodiments of the present invention, wherein the input port 20 is configured to mate with the multi-output battery pack 50 of fig. 10. The multi-voltage output battery pack 50 is provided with a multi-voltage output interface 51, and includes at least a first battery cell (not shown) and a second battery cell (not shown).

A conductive sheet 225 is disposed between the second input terminal 222 and the third input terminal 223, so that the second input terminal 222 and the third input terminal 223 are electrically connected. In this embodiment, the terminal group 22 is the switching mechanism. The arrangement is such that the voltage supplied to the input port 20 by the multi-voltage output interface 51 is a series voltage, that is: the multi-voltage output battery pack 50 outputs the voltage after the battery components are connected in series. In the present embodiment, the second input terminal 222 and the third input terminal 223 are electrically connected, but it is understood that in other embodiments, the first input terminal 221 and the fourth input terminal 224 may be electrically connected as long as the multi-voltage output battery pack 50 can output the series voltage. When the first input terminal 221 and the third input terminal 223 are electrically connected and the second input terminal 222 and the fourth input terminal 224 are electrically connected, the multi-voltage output battery pack 50 outputs a parallel voltage, which is lower than the series voltage.

In this embodiment, the first voltage is a series voltage, and the second voltage is a parallel voltage. It is understood that the voltage output from the multi-voltage output battery pack is not limited to two kinds, but may be various. For example, the battery pack disclosed in chinese patent application No. 201780067581.2 can output three or more voltages. Fig. 7 illustrates one of many embodiments of the present invention, showing an output port 30 for mating with the old power tool 60 of fig. 11. The old electric tool 60 is provided with an input interface (not shown) for matching with an old battery pack that can output only one voltage, and cannot match with the multi-voltage output interface 51. The output port 30 includes a base 31 and a terminal group 32 mounted in the base 31. The terminal group 32 protrudes out of the output terminal slot 111, and includes a first output terminal 321, a communication terminal 322, a charging terminal 323, and a second output terminal 324. Fig. 8 is a schematic diagram illustrating the connection between the output port 30 and the input port 20.

One end of the elastic element 42 is fixedly mounted on the main body 41, and the other end is mounted on the housing 10. When the pressing arm 412 is pressed, the latching arm 411 is driven by the pressing arm 412 to move and enter the receiving cavity from the latching groove 113, and at this time, the elastic element 42 is in an elastic deformation state. When the pressing arm 412 is released, the pressing arm 412 or the retaining arm 411 is reset under the action of the elastic element 42. In the present embodiment, the elastic element 42 is a spring, but in other embodiments, the elastic element 42 may also be an elastic plastic, an elastic sheet, or the like.
