Aiming at the technical defects in the related art, the embodiment provides a mobile power supply. As shown in fig. 1 and 2, the portable power source of the present embodiment includes a housing 100, a plug 200, and a pusher 300. Referring to fig. 4, the housing 100 is provided with a sliding through groove 110, and two locking grooves 120 respectively communicating with two ends of the sliding through groove 110 are concavely formed on the inner wall of the housing 100. In this embodiment, the plug 200 is located within the housing 100. The housing 100 is provided with an extension hole 130 through which the plug 200 extends to the outside of the housing 100. Continuing to refer to fig. 6, the pushing member 300 is connected to the plug 200 through the sliding through groove 110, and a flange portion 310 is provided at a portion of the pushing member 300 located in the housing 100.
In this embodiment, the pushing member 300 and the plug 200 are relatively movable, for example: the push member 300 and the plug 200 form a plug-in connection, whereby the push member 300 can be moved relative to the plug 200.
During the relative movement of the pusher 300 and the plug 200, the flange 310 provided on the pusher 300 is also displaced, so that the flange 310 is separated from or engaged with the locking groove 120 according to the movement of the pusher 300. Specifically, as shown in fig. 6 and 7a, when the pusher 300 is pushed in the right direction in fig. 6, the pusher 300 moves rightward, and at this time, the flange 310 moves rightward along with the pusher 300, so that the flange 310 and the locking groove 120 below are separated from each other.
When the flange 310 and the locking groove 120 are separated from each other, the pushing member 300 is separated from the locking action of the locking groove 120 because the pushing member 300 and the housing 100 do not have an abutting portion, so that the pushing member 300 can move relatively to the housing 100 along the sliding through groove 110. As shown in fig. 7a and 7b in particular, when the pusher 300 is pushed upward in fig. 7b, the pusher 300 can move upward along the sliding through groove 110 because the flange portion 310 is separated from the locking groove 120. In the process of moving the pushing member 300 upward, since the pushing member 300 and the plug 200 are connected to each other, the plug 200 moves upward together with the pushing member 300, and at this time, the plug 200 protrudes to the outside of the housing 100 through the protruding hole 130, so that power can be supplied to the electronic device.
As shown in fig. 7b and 7c, after the plug 200 extends out of the housing 100, in order to prevent the plug 200 from being pushed back into the housing 100 by external pressure, when the push member 300 is pulled in the left direction in fig. 7c, the flange 310 is engaged in the locking groove 120 above, so that an abutment is formed between the push member 300 and the housing 100, and the push member 300 is locked by the locking groove 120, so that the push member 300 cannot move downward along the sliding through groove 110. Accordingly, the plug 200 in the extended state cannot be retracted into the housing 100 even when external pressure is applied, and can be stably plugged into the electronic device.
After the power supply is completed, as shown in fig. 7c, the pushing member 300 is pressed in the right direction of fig. 7c to disengage the flange portion 310 of the pushing member 300 from the locking groove 120 above, and then the pushing member 300 is pushed in the lower direction of fig. 7c to move the pushing member 300 downward and simultaneously drive the plug 200 to retract into the housing 100. Then, in order to prevent the plug 200 from being accidentally pushed out of the housing 100, the pusher 300 is pulled again to engage the flange portion 310 of the pusher 300 with the locking groove 120 below, thereby preventing the pusher 300 from moving along the sliding through groove 110.
As described above, the power supply pins 220 of the portable power source of the present embodiment are retracted inside the housing 100 in the non-charging state, so that the pollution of the external environment to the power supply pins 220 can be reduced, and the reliability of the power supply pins 220 can be maintained.
With continued reference to fig. 2, 3 and 5, the plug 200 includes a support 210 and a power pin 220 connected to the support 210. The support 210 is made of an insulating material and the support 210 is provided with a connection hole 211. The pusher 300 includes a pusher section 320 located outside the housing 100 and a connecting section 330 connected to the pusher section 320 and located inside the housing 100, and the flange portion 310 is provided at a circumferential side of the connecting section 330. A portion of the connection section 330 is movably inserted into the connection hole 211, so that when pressure is applied to the pushing member 300, the connection section 330 and the supporting member 210 can relatively move, thereby forming a relatively movable connection between the entire pushing member 300 and the plug 200.
Further, in order to enable the portable power source of the present embodiment to be applied to electronic devices with different sockets, in some embodiments, a plurality of plugs 200 may be provided, and power supply pins 220 of each plug 200 have different specifications, for example: one power pin 220 is a type-c pin and the other power pin 220 is a lighting pin of an apple. It will be appreciated that when a plurality of plugs 200 are provided, each plug 200 should be provided with a corresponding pusher 300 and sliding channel 110. Since the assembly and operation principle of the other set of the plug 200, the sliding through groove 110 and the pusher 300 are the same as those of the above-described embodiment, the difference is only a specific arrangement position, and the description is not repeated here.
With continued reference to fig. 2 and 6, in order to facilitate engagement and disengagement between the flange portion 310 and the locking groove 120, the mobile power supply further includes an elastic member 400 in some embodiments. The elastic member 400 is located between the support 210 and the flange 310, and both ends of the elastic member 400 are respectively abutted against the flange 310 and the support 210. When the pushing member 300 is pressed, the interval between the flange portion 310 and the supporting member 210 is reduced, so that the elastic member 400 is pressed in an elastically deformed state. When the pushing member 300 is not pressed any more, the elastic restoring force of the elastic member 400 is sufficient to push the flange portion 310, thereby serving for the restoration of the pushing member 300. After the elastic member 400 is adopted, when the pushing member 300 is locked, the flange portion 310 is automatically embedded with the locking groove 120 by the elastic restoring force of the elastic member 400, so that the pushing member 300 is not required to be pulled, and the operation feeling of the mobile power supply is facilitated. The elastic member 400 in the present embodiment is a spring plate or a spring, but is not limited thereto.
With continued reference to fig. 2 and 6, in order to make the layout of the components inside the mobile power supply more compact, in some embodiments, the connection holes 211 provided on the support 210 are blind holes. The elastic member 400 is disposed in the connection hole 211, so that two ends of the elastic member 400 are respectively abutted against the flange portion 310 and the hole bottom of the connection hole 211, thereby eliminating the need for an additional fixing structure for fixing the elastic member 400, and improving the layout compactness of the elastic member 400.
With continued reference to fig. 6, to enable the pusher 300 to stably carry the support 210 of the plug 200, in some embodiments, a portion of the flange portion 310 is inserted into the connection hole 211 when the flange portion 310 is engaged with the locking groove 120 to maintain the connection between the support 210 and the pusher 300. When the flange 310 is separated from the locking groove 120, more parts of the flange 310 are inserted into the coupling hole 211 due to the relative movement between the flange 310 and the supporter 210, and even the entire flange 310 can be inserted into the coupling hole 211, so that the supporter 210 can be stably driven when the pusher 300 moves along the sliding through groove 110.
With continued reference to fig. 2 and 6, in order to shorten the length of the connecting section 330 of the pusher 300 and thereby reduce the risk of breakage of the connecting section 330 during pushing, in some embodiments, the support 210 has a boss 212 protruding toward the connecting section 330, and the connecting hole 211 is opened on the boss 212. Since the boss 212 is integrated with the supporting member 210, and the interval between the housing 100 and the plug 200 can be reduced by the boss 212, the length of the connecting section 330 of the pushing member 300 can be shortened, so that the length of the arm formed when the pushing member 300 is pushed can be reduced, and the risk of breakage of the side of the connecting section 330 close to the plug 200 can be reduced.
Illustratively, when the pusher 300 is pushed along the sliding channel 110, for convenience of pushing, in some embodiments, the push section 320 of the pusher 300 is coupled with the push cap 340, and anti-slip patterns are formed on the surface of the push cap 340, thereby increasing friction between the user's finger and the push cap 340, thereby improving pushing operation of the pusher 300.
As shown in fig. 3, 4 and 6, in order to facilitate assembly of the internal components of the mobile power supply, a partition 140 is provided in the case 100. The partition 140 serves to divide the interior cavity of the housing 100 into a plurality of parts to facilitate the installation of modular internal components. Illustratively, as shown in fig. 3, the partition 140 divides the interior cavity of the housing 100 into upper and lower chambers that communicate with each other. The plug 200 is positioned in the upper chamber in fig. 3, and the protruding hole 130 communicates with the upper chamber to allow the power supply pins 220 of the plug 200 to be extended and retracted outwardly. A control circuit board 600 is also provided in the upper chamber, the control circuit board 600 being electrically connected to the power supply pins 220 through wires 800. To adapt to the telescopic movement of the plug 200, the wire 800 of the present embodiment has a certain reserved portion to correspond to the overhanging state of the plug 200. A battery 700 is provided in the lower chamber in fig. 3, and the battery 700 is electrically connected to the power supply pins 220 through the control circuit board 600 and the wires 800 in sequence. In addition, a charging plug 610 and a switch 620 are electrically connected to the control circuit board 600. The charging plug 610 is exposed outward through the housing 100 for receiving an external power supply line. The charging plug 610 may be a type-c interface or an apple lighting interface, but is not limited thereto. When an external power supply line is plugged into the charging plug 610, the battery 700 can be charged.
Further, the switch 620 is also exposed outward through the case 100, and the switch 620 is used to open and close the conduction between the battery 700 and the power supply pins 220. It will be appreciated that the current state of the switch 620 may be determined by the status of the operating flag of the switch 620 itself or by the status of an additional indicator light. For example: an indicator light may be provided in connection with the switch 620. When the indicator light is turned on, it may be considered that the battery 700 is connected to the power supply pin 220, and power may be supplied to the electronic device through the power supply pin 220. If the indicator light is off, the battery 700 may be considered disconnected from the power pin 220.
With continued reference to fig. 2 and 3, in some embodiments, in order to stably extend and retract the plug 200, a guide rail 500 formed along the length direction of the sliding channel 110 is provided in the housing 100, and the plug 200 is slidably coupled with the guide rail 500. For example, two parallel guide rails 500 may be provided for one plug 200, and a socket for socket connection with the guide rails 500 may be additionally provided on the support member 210 of the plug 200, or the support member 210 itself may be directly socket-connected with the guide rails 500, so as to achieve a sliding connection between the plug 200 and the guide rails 500.
The above description of the preferred embodiments of the present utility model should not be taken as limiting the scope of the utility model, but rather should be understood to cover all modifications, variations and adaptations of the present utility model using its general principles and the following detailed description and the accompanying drawings, or the direct/indirect application of the present utility model to other relevant arts and technologies.
