Description

A portable power bank rental device Technical Field

[0001] This invention relates to the field of shared mobile power charging equipment technology, and in particular to a mobile power rental device. Background Technology

[0002] With the development of the sharing economy, existing mobile power rental equipment generally adopts an all-in-one structure. This all-in-one layout makes the internal systems relatively stable and allows a single machine to store a large number of mobile power banks. However, if one of the charging modules malfunctions and needs repair or replacement, the overall function of the machine is fixed and the functional modules are difficult to replace. The only options are on-site repair or sending the entire machine back for repair, which makes repair inconvenient. Technical issues

[0003] The technical problem to be solved by the present invention is to provide a mobile power rental device that solves the problem that when a certain module of the existing mobile power rental device fails, the functions of the whole machine are fixed, the functional modules are difficult to replace, and due to the inconvenience of disassembly and assembly, the only options are on-site repair or sending the whole machine back for repair, which is inconvenient. Technical solutions

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This invention proposes a mobile power bank rental device, including a housing. The housing contains a main control PCB board and several charging compartment modules arranged in a row. The housing has a mounting cavity with one open end, and the charging compartment modules are detachably installed within the mounting cavity. Each charging compartment module is signal-connected to the main control PCB board. Each charging compartment module includes a compartment frame, a compartment base, a door closing sensor component, and a charging base assembly. The charging base assembly is fastened to the rear end of the compartment frame and is used to identify, charge, lock, or unlock the mobile power bank within the charging compartment module. The door closing sensor component is located on one side of the compartment frame. The compartment frame and the compartment base are detachably connected. The compartment base has ratchet blocks on both sides with multiple locking points. The mounting cavity has slots for engaging the locking points. The free-falling of the ratchet blocks allows the locking points to engage with the slots in the mounting cavity.

[0006] The charging dock assembly includes a compartment base, an NFC sensing board, a compartment lock, a control board, and a back cover. The compartment lock can lock or unlock the power bank inside the charging dock module. The compartment base and the back cover are connected by fasteners to form a cavity. The NFC sensing board, the compartment lock, and the control board are disposed in the cavity. The compartment base is securely connected to the compartment frame by fasteners and buffer components.

[0007] The storage lock comprises a charging base for charging a power bank, a lock cylinder, a top rod, a spring, a mounting base, a sensing top rod, a pull arm, a plate bracket, a sensing plate, and an electromagnet.

[0008] The charging compartment module further includes a photoelectric sensor, a fire extinguishing device, a compartment door lock, and a cooling fan. The photoelectric sensor and the compartment door lock are located on both sides of the compartment frame, and the fire extinguishing device and the cooling fan are located on one side of the compartment frame.

[0009] The installation cavity has a door at its opening, and a door lock is connected to the door. The reciprocating motion of the mobile power supply drives the door to open or close via the door lock.

[0010] The door closing sensing component includes a bracket, a sensor, and a connecting rod. The bracket has a sliding groove. One end of the connecting rod is connected to the door by a pin, and the other end is slidably connected to the sliding groove by a rivet. The sensor is connected to the control board.

[0011] The base of the storage compartment is equipped with a roller assembly, which is used for the rolling of the power bank in and out.

[0012] The inner top wall and the left and right inner walls of the storage passage frame are equipped with anti-collision strips.

[0013] The ratchet block is fixed to the base of the compartment via a pivot. The locking point is located on one side of the ratchet block. One end of the ratchet block gradually increases in size along the locking point. The locking point of the ratchet block is used to resist the impact of the power bank and prevent the charging compartment module from moving backward after the charging compartment module is fixed to the mounting cavity of the housing.

[0014] The housing also includes a display module and several power modules. The display module is connected to the main control PCB board, one of the power modules is electrically connected to the main control PCB board, and the remaining power modules are each electrically connected to a charging compartment module for charging the power bank of the charging compartment module. Beneficial effects

[0015] The portable power bank rental device provided by this invention features a mounting cavity with an opening at one end in the housing. The charging compartment modules are detachably installed within this cavity, and each module is connected to the main control PCB board via signal transmission. This allows the number of charging compartment modules to be adjusted according to different situations, meeting the quantity requirements of various scenarios. If a functional module malfunctions during use, it can be easily replaced and returned to the factory for repair, without significantly affecting the normal operation of the device. Furthermore, the portable power bank rental device can be pre-assembled with charging compartment modules during manufacturing. These modules can be tested individually, offering strong interchangeability and effectively improving overall assembly efficiency, testing efficiency, and rapid after-sales repair and replacement. Manufacturing costs will be significantly reduced, manufacturing difficulty lowered, and subsequent maintenance simplified. Attached Figure Description

[0026] To illustrate the technical solution described in this invention, specific embodiments are described below.

[0027] Please refer to Figures 1 to 6. The mobile power bank rental device 100 provided in this embodiment of the invention includes a housing 10, a main control PCB board (not shown) disposed within the housing 10, and a plurality of charging compartment modules 20 arranged in rows. The housing 10 has a mounting cavity 11 with one end open. The charging compartment modules 20 are detachably disposed in the mounting cavity 11, and each charging compartment module 20 is signal-connected to the main control PCB board. Each charging compartment module 20 includes a compartment frame 30, a compartment base 40, a door closing sensor component 50, and a charging base assembly 60 disposed at the rear end of the compartment frame 30. The compartment frame 30 is a square annular structure, its size being slightly larger than the size of the mobile power bank. The charging base assembly 60 is used to identify, charge, lock, or unlock the mobile power bank (not shown) inside the charging compartment module 20. The door closing sensor component 50 is installed on one side of the compartment frame 30 by fasteners. The compartment frame 30 and the compartment base 40 are detachably connected by fasteners 70. The compartment base 40 has ratchet blocks 41 on both sides, and each ratchet block 41 has multiple locking points 42. The mounting cavity 11 has a locking groove 12. The compartment base 40 allows the locking points 42 to be locked into the locking groove 12 of the mounting cavity 11 by the free downward movement of the ratchet blocks 41. The ratchet blocks 41 are fixed to the compartment base 40 by a rotating shaft 44. The locking points 42 are located on one side of the ratchet blocks 41. One end of the ratchet blocks 41 gradually increases in size along the locking point direction. The locking points of the ratchet blocks 41 are used to resist the impact of the power bank and prevent the charging compartment module 20 from moving backward after it is fixed on the mounting cavity 11 of the housing 10. If a functional module malfunctions during use, simply replace the charging compartment module and return it to the factory for repair; this will not significantly affect the normal use of the device. The charging compartment module can be pre-assembled during the manufacturing process, and the module can be tested independently with high interchangeability. This effectively improves the efficiency of overall assembly, testing, and rapid after-sales repair and replacement.

[0028] In this embodiment of the invention, the charging dock assembly 60 includes a compartment seat 61, an NFC sensing board 62, a compartment lock 63, a control board 64, and a back cover 65.

The NFC sensing board 62, the compartment lock 63, and the control board 64 are disposed in the cavity. The compartment seat 61 is fastened to the compartment frame 30 by fasteners and a buffer 66. The buffer 66 is a rubber part, which is intended to effectively buffer the impact of the power bank on the charging dock assembly when the power bank is pushed in. The NFC sensing board 62 can identify the identity of the power bank pushed in and can feed back ID information to the control board 64. The control board 64 controls the main control PCB board in the background to charge and lock the power bank.

[0029] In this embodiment of the invention, the storage lock 63 includes a charging base (not shown), a lock cylinder (not shown), a top rod (not shown), a spring (not shown), a mounting base (not shown), a sensing top rod (not shown), a pull arm (not shown), a plate bracket (not shown), a sensing plate (not shown), and an electromagnet (not shown) for charging a mobile power supply.

[0030] In this embodiment of the invention, the charging compartment module 20 further includes a photoelectric sensor 21, a fire extinguishing device 22, a compartment door lock 23, and a cooling fan 24. The photoelectric sensor 21 and the compartment door lock 23 are disposed on both sides of the compartment frame 30, and the photoelectric sensor 21 is connected to the control board 64. The photoelectric sensor 21 is a through-beam photoelectric sensor, which is used to determine whether a power bank is pushed in. When a power bank is pushed in, the through-beam sensor 21 is blocked, and a signal is sent to the control board 64. The fire extinguishing device 22 and the cooling fan 24 are fixed on one side of the compartment frame 30. The fire extinguishing device 22 is a fire extinguisher with a lead wire. When the device malfunctions and catches fire while charging the power bank, the lead wire is ignited, which will activate the fire extinguishing device 22 to spray fire extinguishing material, effectively extinguishing the fire and preventing the accident from escalating further. The cooling fan 24 is fixed on one side of the compartment frame 30, and its air outlet is directly facing the power bank inside the compartment frame 30, for the purpose of cooling the power bank.

[0031] In this embodiment of the invention, the opening of the mounting cavity 11 is provided with a door 13, and the door lock 23 is connected to the door 13. The reciprocating motion of the portable power supply is driven by the door lock 23 to open or close the door 13. Thus, the portable power supply can be put into the charging compartment module 30 through the door 13, or the portable power supply can be pushed out of the door 13.

[0032] In this embodiment of the invention, the door closing sensing component 50 shown in Figure 4 comprises a bracket 51, a sensor 52, and a connecting rod 53.
