The following describes an embodiment of the present invention based on its overall structure.
[0028] See also Figure 1-4 , this embodiment provides a Bluetooth-based offline battery replacement system, including:
[0029] The box body includes a base 1 and an isolation box 2. The isolation box 2 is plugged into the top of the base 1. The base 1 is a hollow structure. There are several charging seats 3 on both sides of the isolation box 2. The charging seats 3 are located on the top of the base 1. Several battery storage compartments 4 are provided on the side of the base 1. Each charging seat 3 corresponds to a battery storage compartment 4.
[0030] A card slot 5 is provided on the top of the base 1, and the isolation box 2 is snapped onto the card slot 5. A support frame 6 is provided at the opening of the card slot 5, and a film 7 is laid on the support frame 6. A through-hole 8 is passed through the isolation box 2, and the through-hole 8 corresponds to the opening of the card slot 5. The through-hole 8 is plugged with fire sand.
[0031] The Bluetooth hub is installed inside the box and includes several Bluetooth chips and a switching unit. Each charging seat 3 corresponds to a Bluetooth chip. The switching unit is used to switch the communication path between the external mobile communication device, the Bluetooth chip and the electric bicycle's onboard Bluetooth system.
[0032] In the above scheme, when the base 1 of the box body is in the process of battery replacement and charging, if a short circuit and fire occur due to aging of the line or other reasons, the film 7 pasted on the support frame 6 will be burned, and the fire sand in the perforation 8 will enter the inner wall of the base 1, isolating the batteries stored in the battery storage compartment 4 at the bottom. The purpose of using the fire sand to extinguish the open flame is conducive to reducing the fire, buying precious time for fire extinguishing, and improving safety.
[0033] At the same time, a slot 5 is provided in the middle of the top of the base 1 to facilitate the engagement of the isolation box 2 with the slot 5, and to facilitate the fire sand to fall into the base 1 in alignment with the opening of the slot 5. When a fault occurs on one side of the charging station 3 during charging, the isolation box 2 can isolate and prevent fire on the other side.
[0034] It is also noted that the Bluetooth hub contains multiple Bluetooth chips, and the working principle and structural composition of the Bluetooth hub can be referred to the Bluetooth hub disclosed in publication number CN209738844U, which realizes the binding of one Bluetooth chip to a charging seat 3 and a battery storage compartment 4. When the electric bicycle needs to be replaced with a battery, the external mobile communication device communicates with the Bluetooth chip therein to complete the communication with the on-board Bluetooth system on the electric bicycle. At this time, since the charging seat 3 is bound to the Bluetooth chip therein, the corresponding charging seat 3 can be selected for charging, and a new battery can be obtained from the battery storage compartment 4 and put into the electric bicycle for use. Moreover, the on-board Bluetooth system connects the corresponding Bluetooth chip, that is, the corresponding charging seat 3 and battery model, to complete the charging and battery replacement of the electric bicycle.
[0035] As a preferred embodiment, a partition 9 is installed inside the base 1 at the position of the card slot 5, and the partition 9 divides the inside of the base 1 into two cavities.
[0036] In the above scheme, the partition 9 divides the interior of the base 1 into two cavities, and the partition 9 is made of fire-proof and high-temperature resistant material, which can isolate the batteries on both sides to prevent a failure on one side from affecting the battery on the other side. At the same time, the partition 9 is located in the center of the slot 5. During the falling process, the fire sand slides on both sides. In order to achieve a better sliding effect, an arc-shaped plate structure can be set on both sides of the bottom of the partition 9, which helps the fire sand slide from the partition 9 to the battery, playing a role in fire extinguishing and heat insulation.
[0037] As a preferred embodiment, extension plates 10 are provided on both sides of the bottom of the isolation box 2 , and the extension plates 10 are snap-connected to the outer sides of the slots 5 .
[0038] In the above scheme, the bottom of the isolation box 2 is just inserted into the slot 5, and the extension plates 10 on both sides are inserted along the side walls of the base 1. At this time, the isolation box 2 can be just snapped into the slot 5 in the horizontal and longitudinal directions, thereby improving the stability of the isolation box 2. At the same time, in order to improve its stability, the isolation box 2 can be fixed to the side of the base 1 by passing long screws through the extension plates 10.
[0039] As a preferred embodiment, a box cover 11 is provided on the top of the isolation box 2 , and the box cover 11 covers the through hole 8 .
[0040] In the above solution, the box cover 11 can be fixed to the top of the isolation box 2 by screws, covering the perforation 8 to prevent the fire sand from scattering from the opening of the perforation 8 or other substances from falling into other impurities.
[0041] As a preferred embodiment, a plurality of ventilation holes 12 are provided on both sides of the base 1 , and the plurality of ventilation holes 12 are located below the two ends of the card slot 5 .
[0042] In the above scheme, the ventilation holes 12 are set at corresponding positions at both ends of the card slot 5. When no fault occurs, the ventilation holes 12 on both sides play a role in ventilation and heat dissipation. When a fire occurs, after the film 7 is burned, the fire sand inside the isolation box 2 falls to the ventilation holes 12 in the first time, blocking the ventilation holes 12 in the first time, isolating the air from the inside of the base 1, and reducing the fire inside the base 1.
[0043] As a preferred embodiment, a plurality of cross bars 13 are spaced apart between the support frames 6 .
[0044] In the above solution, the cross bar 13 supports the film 7 to prevent the film 7 from being squeezed by the fire sand and thus being broken.
[0045] As a preferred embodiment, two cross bars 13 close to the ventilation hole 12 are provided with guide plates 14 inclined toward one side of the ventilation hole 12 .
[0046] In the above scheme, the guide plate 14 is made of fireproof and high-temperature resistant material. When a fire occurs in the base 1, the guide plate 14 inclined toward the ventilation hole 12 can more specifically introduce fire sand into the ventilation hole 12, block the ventilation hole 12 in time, and isolate the fire source inside the base 1 from the air.
[0047] The foregoing descriptions of specific exemplary embodiments of the present invention are for the purpose of illustration and description. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials or characteristics described can be combined in an appropriate manner in any one or more embodiments or examples.
