Description

Technical Field

[0001] The present invention relates to the technical field of chargers, and in particular to an energy storage charging stand. Background Art

[0002] With the popularity of mobile devices, the safety and convenience of the charging stand as a commonly used charging device has become increasingly important. Existing charging stands usually use two positive and negative springs protruding from the surface of the charging stand to contact the charging interface of the energy storage power supply to transmit power. However, this design has certain safety hazards, especially when the user operates improperly.

[0003] In the design of conventional charging stations, the positive and negative pole springs are directly exposed and protrude from the surface of the charging station. Although such a design is conducive to quickly positioning and inserting the device, it also brings some potential problems.

[0004] Since the positive and negative shrapnel are directly exposed, if the user accidentally touches the two shrapnel at the same time during use, a short circuit will occur. In addition, if a metal object accidentally falls between the two shrapnel, a short circuit will also occur.

[0005] In addition, the exposed shrapnel can easily form a conductive path in a humid environment, increasing the possibility of leakage. This risk is more obvious when used in high humidity environments such as kitchens and bathrooms. Summary of the invention

[0023] In this embodiment, the annular metal terminal 31 is directly arranged on the top surface of the truncated cone portion 2, and the metal contact terminal 33 is arranged in the accommodating cavity 11.

In the energy storage charging seat described in the present embodiment, a positioning column 61 is provided in the accommodating chamber 11; a cable reel 7 is provided for rotation outside the positioning column 61; a power cord 62 is wound around the cable reel 7; one end of the power cord 62 protrudes out of the body 1; a linkage assembly is provided between the cable reel 7 and the driving seat 5. In the energy storage charging seat described in this embodiment, a placement groove 71 is provided on the top of the cable reel 7; the drive seat 5 is lifted and slidably arranged outside the positioning column 61; the drive seat 5 is matched with the positioning column 61 in a profile; the drive seat 5 is movably and telescopically arranged in the placement groove 71; the linkage assembly includes a spiral groove 53 arranged on the outer wall of the drive seat 5 and a drive pin 72 arranged on the inner wall of the placement groove 71; the drive pin 72 is movably arranged in the spiral groove 53. In the energy storage charging seat described in this embodiment, a coil spring 73 is provided between the bottom of the cable reel 7 and the accommodating chamber 11. In the energy storage charging seat described in this embodiment, a ratchet 74 is provided on the outer periphery of the cable reel 7; a ratchet 81 that cooperates with the ratchet 74 is movably provided in the accommodating chamber 11; the ratchet 81 is connected to a pull rod 82; the pull rod 82 protrudes out of the body 1; a reset spring 83 is provided between the pull rod 82 and the accommodating chamber 11.

[0029] Specifically, when the energy storage charging stand described in this embodiment is not in use, under the action of the winding spring 73, most of the power cord 62 is wound in the winding reel 7, the driving seat 5 is retracted into the placement groove 71, the first abutment slope 52 is separated from the second abutment slope 41, and under the action of the abutment spring 42, the limit pin 4 is retracted back into the limit groove 25; at this time, the energy storage power supply 9 can be directly placed on the truncated cone 2.

[0030] When the energy storage power source 9 needs to be charged, the truncated cone groove 91 of the energy storage power source 9 is aligned with the truncated cone portion 2 of the body 1, and then the truncated cone portion 2 is inserted into the truncated cone groove 91, so that the first metal terminal 92 can be inserted into the through hole 21 and contact the metal contact terminal 33 at the bottom of the through hole 21, and the second metal terminal 93 contacts the annular metal terminal 31, so that the energy storage charging seat is connected to the energy storage power source 9; Then the power cord 62 is pulled out to connect with the external socket. In the process of pulling the power cord 62, the winding drum 7 rotates accordingly, and the winding spring 73 is deformed. In the process of rotating the winding drum 7, under the cooperation of the driving pin 72 and the spiral groove 53, the driving seat 5 is driven to move upward, and the driving arm 51 moves upward until the first abutting inclined surface 52 abuts against the second abutting inclined surface 41, the limiting pin 4 compresses the abutting spring piece 42 and the limiting pin 4 extends from the limiting groove 25 to the side of the truncated cone 2, wherein the storage The conical groove 91 of the energy power source 9 is provided with an annular groove 94; the limit pin 4 is clamped with the annular groove 94, so that the energy storage charging seat is connected to the energy storage power source 9, which can ensure that the energy storage charging seat can stably charge the energy storage power source 9, and under the action of the reset spring 83, the pawl 81 and the ratchet 74 are clamped to prevent the reel 7 from resetting; at the same time, the energy storage charging seat and the energy storage power source 9 are locked. During transportation, the energy storage charging seat and the energy storage power source 9 can be transported at the same time to prevent the charging seat from being lost.

[0031] When the lock needs to be released, one only needs to pull the pull rod 82 to separate the pawl 81 from the ratchet 74. Under the action of the coil spring 73, the cable reel 7 is reset and rotates in the opposite direction, so that with the cooperation of the drive pin 72 and the spiral groove 53, the drive seat 5 is driven to move upward again, and the first abutting bevel 52 is separated from the second abutting bevel 41. Under the action of the abutting spring 42, the limit pin 4 shrinks back into the limit groove 25; at this time, the energy storage power supply 9 can be separated from the energy storage charging seat.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
