Description

Technical Field

[0001] This invention relates to the field of charger technology, and more specifically to an energy storage charging stand. Background Technology

[0002] With the widespread use of mobile devices, the safety and convenience of charging docks, as commonly used charging devices, have become increasingly important. Existing charging docks typically use two positive and negative contacts protruding from the surface of the dock to contact the charging interface of the power storage device for power transfer. However, this design presents certain safety hazards, especially in cases of improper user operation.

[0003] In conventional charging dock designs, the positive and negative contacts are directly exposed and protrude from the surface of the charging dock. While this design facilitates quick positioning and insertion of devices, it also introduces some potential problems.

[0004] Because the positive and negative contacts are directly exposed, a short circuit can occur if the user accidentally touches both contacts simultaneously during use. Additionally, a short circuit can also be caused if a metal object is accidentally dropped between the two contacts.

[0005] In addition, exposed springs are prone to forming conductive paths in humid environments, increasing the possibility of leakage, especially when used in high-humidity environments such as kitchens and bathrooms, where this risk is more pronounced. Summary of the Invention

[0013] The inner wall of the accommodating cavity is provided with a fixing groove; a retaining spring is provided between one end of the limiting pin and the fixing groove.

[0014] The present invention is further configured such that: a positioning post is provided inside the accommodating cavity; a winding reel is rotatably provided outside the positioning post; a power cord is wound around the winding reel; one end of the power cord protrudes out of the body; and a linkage component is provided between the winding reel and the drive seat.

[0030] The present invention will be further described in conjunction with the following embodiments.

[0031] Depend on Figures 1 to 8As can be seen, the energy storage charging base described in this embodiment includes a body 1; the body 1 has a receiving cavity 11; the top of the body 1 has a frustum 2; the top surface of the frustum 2 has an annular metal terminal 31; the top surface of the frustum 2 has a through hole 21 communicating with the receiving cavity 11; the receiving cavity 11 has a metal contact terminal 33; the metal contact terminal 33 is located at the bottom of the through hole 21; the receiving cavity 11 has a circuit board 12; the annular metal terminal 31 and the metal contact terminal 33 are respectively connected to the circuit board 12.

[0032] Specifically, in this embodiment, the energy storage charging base has a frustum groove 91 at the bottom of the energy storage power supply 9 that mates with the frustum portion 2, and a first metal terminal 92 and a second metal terminal 93 are provided on the bottom surface of the frustum groove 91. When the energy storage power supply 9 needs to be charged, the frustum groove 91 of the energy storage power supply 9 is aligned with the frustum portion 2 of the body 1, and then the frustum portion 2 is inserted into the frustum groove 91. This allows the first metal terminal 92 to be inserted into the through hole 21 and contact the metal contact terminal 33 at the bottom of the through hole 21, while the second metal terminal 93 contacts the annular metal terminal 31. This allows the energy storage charging base to connect with the energy storage power supply 9, enabling the energy storage charging base to charge the energy storage power supply 9.

[0033] In this embodiment, by directly setting the annular metal terminal 31 on the top surface of the frustum portion 2 and setting the metal contact terminal 33 in the accommodating cavity 11, and setting the metal contact terminal 33 at the bottom of the through hole 21, it can effectively prevent the user from directly contacting the annular metal terminal 31 and the metal contact terminal 33, and can also prevent external metal parts from simultaneously contacting the annular metal terminal 31 and the metal contact terminal 33 and causing a short circuit. This can protect the energy storage charging base and improve safety performance.

[0034] In this embodiment, an energy storage charging base is provided with an annular groove 23 on the top surface of the frustum portion 2; a through hole 21 is provided in the middle of the annular groove 23; and an annular metal terminal 31 is provided in the annular groove 23.

[0035] Specifically, the annular groove 23 facilitates the fixing of the annular metal terminal 31; in addition, by setting the through hole 21 in the middle of the annular groove 23, the energy storage power supply 9 can be placed on the body 1 at different rotation angles, thereby improving the overall applicability.

[0036] In this embodiment, an energy storage charging base is provided with a through hole 24 at the bottom of the annular groove 23, communicating with the accommodating cavity 11; a connecting arm 32 is provided at the bottom of the annular metal terminal 31; the connecting arm 32 passes through the through hole 24 and connects to the circuit board 12 inside the accommodating cavity 11. The above arrangement facilitates the connection between the annular metal terminal 31 and the circuit board 12.

[0037] In this embodiment, an energy storage charging base has a guide slope 22 at the top of the through hole 21; the cross-section of the metal contact terminal 33 is arc-shaped. By providing the guide slope 22, it is easy for the first metal terminal 92 to be inserted into the through hole 21; the arc-shaped metal contact terminal 33 gives the terminal a certain degree of elasticity, and the second metal terminal 93 of the energy storage power supply 9 is also arc-shaped; the above-mentioned configuration can enhance the stability of the overall structure.

[0038] In this embodiment, an energy storage charging base has a limiting groove 25 on the side of the frustum portion 2; a limiting pin 4 is telescopically movably provided in the limiting groove 25. In this embodiment, an energy storage charging base has a driving seat 5 that is movably raised and lowered within the accommodating cavity 11; a driving arm 51 is provided at the top of the driving seat 5; a first abutting inclined surface 52 is provided at the end of the driving arm 51; one end of the limiting pin 4 protrudes into the accommodating cavity 11 and has a second abutting inclined surface 41 that cooperates with the first abutting inclined surface 52; a fixing groove 43 is provided on the inner wall of the accommodating cavity 11; an abutting spring 42 is provided between one end of the limiting pin 4 and the fixing groove 43. In this embodiment, an energy storage charging base has a positioning post 61 within the accommodating cavity 11; a winding reel 7 is rotatably provided outside the positioning post 61; a power cord 62 is wound around the winding reel 7; one end of the power cord 62 protrudes from the body 1; a linkage assembly is provided between the winding reel 7 and the driving seat 5. In this embodiment of the energy storage charging base, the top of the reel 7 is provided with a placement groove 71; the drive seat 5 is slidably and vertically disposed outside the positioning post 61; the drive seat 5 and the positioning post 61 are shaped and fitted; the drive seat 5 is movably and telescopically disposed in the placement groove 71; the linkage component includes a spiral groove 53 disposed on the outer wall of the drive seat 5 and a drive pin 72 disposed on the inner wall of the placement groove 71; the drive pin 72 is movably disposed in the spiral groove 53. In this embodiment of the energy storage charging base, a coil spring 73 is provided between the bottom of the reel 7 and the accommodating cavity 11. In this embodiment of the energy storage charging base, the outer periphery of the reel 7 is provided with ratchet teeth 74; a pawl 81 that engages with the ratchet teeth 74 is movably disposed in the accommodating cavity 11; the pawl 81 is connected to a pull rod 82; the pull rod 82 protrudes out of the body 1; a return spring 83 is provided between the pull rod 82 and the accommodating cavity 11.

[0039] Specifically, in this embodiment, when the energy storage charging base is not in use, under the action of the coil spring 73, most of the power cord 62 is wound into the coil spool 7, the drive seat 5 retracts into the placement groove 71, the first abutting inclined surface 52 separates from the second abutting inclined surface 41, and under the action of the abutting spring 42, the limiting pin 4 retracts back into the limiting groove 25; at this time, the energy storage power supply 9 can be directly placed on the frustum portion 2.

[0040] When it is necessary to charge the energy storage power supply 9, align the frustum groove 91 of the energy storage power supply 9 with the frustum part 2 of the main body 1, and then insert the frustum part 2 into the frustum groove 91. This allows the first metal terminal 92 to be inserted into the through hole 21 and to contact the metal contact terminal 33 at the bottom of the through hole 21. At the same time, the second metal terminal 93 contacts the annular metal terminal 31, thereby connecting the energy storage charging base with the energy storage power supply 9.

[0041] Then, the power cord 62 is pulled out and connected to an external socket. During the pulling of the power cord 62, the reel 7 rotates, and the coil spring 73 deforms. As the reel 7 rotates, the drive pin 72, in cooperation with the spiral groove 53, drives the drive seat 5 upwards, and the drive arm 51 upwards until the first abutting inclined surface 52 abuts against the second abutting inclined surface 41. The limiting pin 4 compresses the abutting spring 42, and the limiting pin 4 extends from the limiting groove 25 to the side of the frustum 2, where the storage... The frustum groove 91 of the power supply 9 is provided with an annular slot 94; the limiting pin 4 is locked with the annular slot 94, thereby connecting the energy storage charging base with the energy storage power supply 9, ensuring that the energy storage charging base stably charges the energy storage power supply 9, and under the action of the return spring 83, the pawl 81 and the ratchet 74 are locked to prevent the winding reel 7 from resetting; at the same time, the energy storage charging base and the energy storage power supply 9 are locked, so that the energy storage charging base and the energy storage power supply 9 can be transported at the same time during transportation to prevent the charging base from being lost.

[0042] When it is necessary to release the lock, simply pull the lever 82 to separate the pawl 81 from the ratchet 74. Under the action of the coil spring 73, the winding reel 7 resets and rotates in the opposite direction. Thus, with the cooperation of the drive pin 72 and the spiral groove 53, the drive seat 5 is driven to move upward again. The first abutting inclined surface 52 separates from the second abutting inclined surface 41. Under the action of the abutting spring 42, the limiting pin 4 retracts back into the limiting groove 25. At this time, the energy storage power supply 9 can be separated from the energy storage charging base.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
