[0027] Reference Figure 1-7 The figure shows a preferred embodiment of the present invention.

[0028] A simple power bank locking device includes a translation structure 1, a push member 2, a driving member 3 and a driving motor 4. The driving member 3 and the driving motor 4 are assembled and arranged, and the driving motor 4 is used to drive the driving member 3 to be arranged in a rotational manner; the translation structure 1 includes a first translation member 11, a translation spring 12 and a second translation member 13. The two ends of the translation spring 12 are respectively docked with the first translation member 11 and the second translation member 13, and the translation spring 12 is used to apply elastic force to drive the first translation member 11 or the second translation member 13 to lock the power bank; the first translation member 11 includes a first translation rod 111, the second translation member 13 includes a second translation rod 131, and the pushing member 2 includes a pushing portion 21. The pushing portion 21 is located between the first translation rod 111 and the second translation rod 131, and the pushing portion 21 is used to be driven by the driving member 3 to apply a lateral pushing force to the first translation rod 111 or the second translation rod 131.

[0029] The above-mentioned simple power bank locking device, when in the locked state, under the action of the translation spring 12, pushes the first translation member 11 and the second translation member 13 to move respectively in the direction away from the translation spring 12 until the first translation member 11 and the second translation member 13 respectively lock different power banks, thereby realizing two-way locking of the power banks. A single locking device realizes dual power bank locking, which reduces the cost of the locking device and helps save space, and facilitates the setting of the locking device; when unlocking, the driving motor 4 outputs a driving force to make the driving member 3 rotate forward or reverse. Since the pushing part 21 is between the first translation rod 111 and the second translation rod 131, the first translation rod 111 or the second translation rod 131 is pushed through the forward and reverse rotation of the driving member 3, thereby prompting the first translation member 11 or the second translation member 13 to separate from the power bank, thereby realizing unlocking the power bank; in this way, the structure of the locking device is simplified, the use of parts is reduced, the manufacturing cost of the locking device is reduced, and at the same time, the repair and maintenance cost of the locking device is reduced.

[0030] The simple power bank locking device includes a locking shell 5, on which the translation structure 1, the push member 2, the driving member 3 and the driving motor 4 are respectively assembled; under the action of the locking shell 5, the assembly of the translation structure 1, the push member 2, the driving member 3 and the driving motor 4 is realized.

[0031] The pushing member 2 includes a pushing seat 22 and a force-bearing portion 23. The pushing seat 22 is movably assembled with the locking shell 5. The pushing portion 21 and the force-bearing portion 23 are respectively docked with the pushing seat 22, and the pushing portion 21 and the force-bearing portion 23 are extended in opposite directions. The driving member 3 is used to drive the pushing member 2 to rotate.

[0032] In this way, the driving member 3 applies a driving force to the force-bearing part 23, and the force-bearing part 23 drives the push seat 22 to rotate, thereby driving the push part 21, so that the push part 21 has a driving force, and then the first translation rod 111 and the second translation rod 131 are driven, so that the first translation member 11 or the second translation member 13 is translated, thereby realizing the unlocking of the power bank.

[0033] The locking shell 5 includes a first shell 51 and a second shell 52, and the first shell 51 and the second shell 52 are assembled. The first shell 51 has a first push limit groove, and the second shell 52 has a second push limit groove 521. The first push limit groove and the second push limit groove 521 are arranged correspondingly, and the first push limit groove and the second push limit groove 521 are respectively arranged in an arched arc shape in the direction away from the driving member 3; the pushing part 21 includes a pushing block 211 and two pushing columns 212, the pushing block 211 is located between the first translation rod 111 and the second translation rod 131, the inner end of the pushing column 212 is docked with the pushing block 211, and the outer end of the pushing column 212 is extended in the direction away from the pushing block 211, and the two pushing columns 212 are respectively embedded with the first push limit groove and the second push limit groove 521.

[0034] In this way, under the cooperation of the first pushing limit groove and the second pushing limit groove 521, the movement of the pushing part 21 is guided and limited, thereby preventing the pushing part 21 from deflecting during movement, ensuring that the pushing part 21 moves along a predetermined path, facilitating the application of the driving force and facilitating the resetting of the first translation member 11 or the second translation member 13, and further facilitating the unlocking and locking of the power bank.

[0035] The first shell 51 has a first restricted groove, and the second shell 52 has a second restricted groove 522. The first restricted groove and the second restricted groove 522 are arranged correspondingly, and the first restricted groove and the second restricted groove 522 are respectively arranged in an arched arc shape in the direction toward the driving member 3; the force-bearing part 23 includes a force block 231 and two force columns 232, the inner end of the force column 232 is arranged in a docking relationship with the force block 231, and the outer end of the force column 232 is extended in a direction away from the force block 231, and the two force columns 232 are respectively embedded in the first restricted groove and the second restricted groove 522.

[0036] In this way, under the cooperation of the first restricted groove and the second restricted groove 522, the movement of the force-bearing part 23 is guided and limited, thereby avoiding deviation when the force-bearing part 23 moves, ensuring that the force-bearing part 23 moves along a predetermined path, and facilitating the force-bearing part 23 to swing under the driving force and reset when the driving force is canceled.

[0037] The pushing portion 21 and the force-bearing portion 23 are symmetrically arranged along the pushing seat 22. When unlocked, the pushing portion 21 and the force-bearing portion 23 rotate along the circumference of the pushing seat 22 respectively, so that the pushing member 2 rotates in a circle when driven by a driving force, thereby improving the rotation stability of the pushing member 2.

[0038] The driving member 3 includes a driving shell 31 and a cam portion 32. The driving shell 31 is assembled with the driving motor 4. The inner end of the cam portion 32 is docked with the driving shell 31, and the outer end of the cam portion 32 is convex in the radial direction. The cam portion 32 is used to drive the force-bearing portion 23 to swing in the radial direction.

[0039] In this way, the driving motor 4 applies a driving force to the driving shell 31, causing the driving shell 31 to rotate. When the driving shell 31 rotates, the cam part 32 is driven to swing. Through the swing of the cam part 32, the driving force is applied to the force-bearing part 23, thereby pushing the first translation rod 111 or the second translation rod 131, and completing the unlocking of the power bank.

[0040] Limit grooves are formed at both ends of the first restricted groove. When the force-bearing column 232 is in the limit groove, the cam portion 32 and the force-bearing block 231 are separated. In this way, through the interference and separation between the cam portion 32 and the force-bearing block 231, a driving force is applied to the first translation rod 111 or the second translation rod 131 respectively, thereby realizing the unlocking of the power bank in both directions.

[0041] The first shell 51 has a first shell 51 fixed portion, and the second shell 52 has a second shell 52 fixed portion. The first shell 51 fixed portion and the second shell 52 fixed portion are arranged correspondingly. The first shell 51 fixed portion is located between the first pushing groove and the first restricted groove, and the second shell 52 fixed portion is located between the second pushing groove 521 and the second restricted groove 522. The sliding seat 22 has a seat body 221 and two seat columns 222. The inner ends of the seat columns 222 are arranged to be docked with the seat body 221, and the outer ends of the two seat columns 222 are respectively movably embedded in the first shell 51 fixed portion and the second shell 52 fixed portion.

[0042] In this way, under the action of the fixed part of the first shell 51 and the fixed part of the second shell 52, the sliding seat 22 is limited and positioned, thereby improving the assembly stability of the sliding seat 22 and ensuring that the sliding seat 22 rotates in a circle under the driving force, thereby realizing the unlocking of the power bank.

[0043] The first shell 51 has a first fixed seat plate 511 and a second fixed seat plate 512. Along the radial direction of the seat body 221, the first fixed seat plate 511 and the second fixed seat plate 512 are respectively arranged in a flat shape. The seat body 221 is located between the first fixed seat plate 511 and the second fixed seat plate 512, and the first fixed seat plate 511 and the second fixed seat plate 512 respectively resist the seat body 221; in this way, under the cooperation of the first fixed seat plate 511 and the second fixed seat plate 512, the seat body 221 is positioned and restricted, thereby improving the stability of the seat body 221, preventing the seat body 221 from shaking or deflecting, ensuring that the seat body 221 rotates in a circle under the driving force, and ensuring that the power bank is unlocked.

[0044] The first translation member 11 has a first inner cavity, the second translation member 13 has a second inner cavity, the first inner cavity and the second inner cavity are arranged in communication, and the two ends of the translation spring 12 are respectively embedded in the first inner cavity and the second inner cavity; in this way, under the cooperation of the first inner cavity and the second inner cavity, the setting stability of the translation spring 12 is enhanced, and at the same time, it is convenient for the translation spring 12 to apply elastic force to the first translation member 11 and the second translation member 13 to cause the first translation member 11 and the second translation member 13 to lock the power bank.

[0045] The first translation member 11 and the second translation member 13 are arranged in an interlaced and overlapping manner, realizing bidirectional locking or unlocking of the power bank. At the same time, the first translation member 11 and the second translation member 13 position and cooperate with each other, thereby improving the assembly stability of the first translation member 11 and the second translation member 13, and ensuring the movement stability of the first translation member 11 or the second translation member 13 when it moves.

[0046] The first translation member 11 and the second translation member 13 are arranged to translate along the deformation direction of the translation spring 12 under the driving force; in this way, the driving member 3 applies a driving force to the first translation member 11 or the second translation member 13, overcomes the elastic force of the translation spring 12, and prompts the first translation member 11 or the second translation member 13 to move in the direction toward the translation spring 12, compressing the translation spring 12 until the first translation member 11 or the second translation member 13 is in an unlocked state with the power bank.

[0047] The first translation member 11 includes a first locking block, which is used to lock or unlock the power bank. The first locking block has a first locking surface 112, and the first locking surface 112 is arranged parallel to the insertion direction of the power bank; the second translation member 13 includes a second locking block, which is used to lock or unlock the power bank. The second locking block has a second locking surface 132, and the second locking surface 132 is arranged parallel to the insertion direction of the power bank.

[0048] Since the first lock surface 112 and the second lock surface 132 are arranged parallel to the insertion direction of the power bank, even if a thin tool is used to insert, the first lock block or the second lock block cannot be pushed back, thereby preventing the power bank from being unlocked abnormally and theft.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
