DETAILED DESCRIPTION

[0032] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0033] like Figure 1-4 A high-safety fast-charging electric bicycle battery exchange system shown in the figure includes an intelligent battery exchange cabinet 16 and a fast-charging battery pack 14. The intelligent battery exchange cabinet 16 includes a cabinet body 1, which is provided with several charging cavities 2. The fast-charging battery pack 14 can be placed in the charging cavity 2. The cabinet body 1 is equipped with an electrical module that converts AC power into DC power. Therefore, the intelligent battery exchange cabinet 16 can be directly connected to the residential power line without the need for separate adapter lines or transformers, reducing the difficulty of promotion and laying costs.

[0034] Specifically, the electrical module is connected to the charging line 4. The electrical module converts the current and voltage into the values ​​required by the fast-charging battery pack 14 and outputs them through the charging line 4. Since the fast-charging battery pack 14 can charge and discharge at a high rate and high frequency compared to existing lithium battery packs and lead-acid battery packs, the charging speed is relatively fast, and charging can be completed in 6-10 minutes.

[0035] Specifically, it can achieve fast charging while not affecting the battery life. Due to the fast charging speed, the battery utilization rate is greatly improved. Therefore, the charging chamber 2 of the smart battery exchange cabinet 16 does not need to be set too many to meet the user's battery exchange needs. Due to the reduction of the charging chamber 2, the volume of the battery exchange cabinet is also reduced, and the area occupied by the public area of ​​the community is relatively small, which is convenient for promotion.

[0036] A main control unit is installed on the cabinet body 1 of the utility model. The main control unit is the control unit of the entire charging cabinet system. The main control unit is connected to the electrical module and can realize functions such as battery monitoring, charging module control, charging process management, equipment self-test, fault alarm and cloud interaction data, thereby realizing the intelligence of the smart charging cabinet and improving the safety of the battery replacement system.

[0037] The fast-charging battery pack 14 of the present invention includes a housing 13 and several safety batteries connected in series and parallel. The safety batteries are installed inside the housing 13. Batteries are a crucial part of the battery swap system. These safety batteries are oxide alloy batteries that are non-flammable and non-explosive. The high safety of the batteries greatly improves the safety of the entire battery swap system, thereby eliminating user concerns about the safety of the battery swap system.

[0038] In addition, the oxide alloy battery is a quasi-solid-state battery with almost no liquid inside its cell. It has the advantage of not losing power in low-temperature environments, which solves the battery life anxiety of northern users in winter. The good experience makes it easy to promote.

[0039] The utility model has a placement table installed in the charging chamber 2 for facilitating the removal and placement of the fast-charging battery pack 14. The charging cable 4 is installed in the charging chamber 2. One end of the fast-charging battery pack 14 is provided with a charging port 11 adapted to the charging cable 4. The charging port 11 is installed at one end of the housing 13. The end of the housing 13 where the charging port 11 is installed is provided with a handle 10 for facilitating removal and placement.

[0040] Specifically, the handle 10 is set at one end of the charging port 11 to facilitate the user to take and place the fast-charging battery pack 14. The user grasps the handle 10 and places the fast-charging battery pack 14 into the charging cavity 2, and then connects the charging cable 4 to the charging port 11 to achieve charging.

[0041] The utility model provides a high-safety fast-charging electric bicycle battery replacement system, which also includes an electric vehicle. The electric vehicle is provided with a battery mounting box, and the fast-charging battery pack 14 can be placed in the battery mounting box, which facilitates the rapid installation and battery replacement of the fast-charging battery pack 14, and the operation is simple to improve the user experience.

[0042] The placement table of the present utility model includes a lifting plate 15, one end of which is rotatably mounted on the inner wall of the lower end of the charging chamber 2. A driving assembly for driving the lifting plate 15 to rotate is installed in the charging chamber 2. The lower end surface of the lifting plate 15 is provided with a mounting groove 17. The driving assembly includes an electric push rod 19, and the telescopic end of the electric push rod 19 is hinged with a connecting rod 18 that is tilted upward along the telescopic direction of the electric push rod 19. The end of the connecting rod 18 away from the electric push rod 19 is hinged to the mounting groove 17. When the lower end surface of the lifting plate 15 contacts the charging chamber 2, the electric push rod 19 is located in the mounting groove 17, saving space in the charging chamber 2 and indirectly reducing the volume of the cabinet 1.

[0043] Specifically, the electric push rod 19 extends, driving the connecting rod 18 to move. The movement of the connecting rod 18 applies an upward force to the lifting plate 15, causing the lifting plate 15 to rotate about the hinge with the charging chamber 2. This raises the height of the fast-charging battery pack 14 placed on the lifting plate 15. This prevents rainwater or moisture from entering the charging chamber 2, forming accumulated water or water droplets at the bottom that come into contact with the fast-charging battery pack 14, extending the service life of the fast-charging battery pack 14 and improving the safety of the intelligent battery swap cabinet 16.

[0044] A support platform 6 is provided on the upper end surface of the lifting plate 15 of the utility model, and a surrounding plate 7 is provided on both sides of the lifting plate 15. A plurality of rollers 5 are provided between the surrounding plate 7 and the support platform 6 to reduce the friction when the fast-charging battery pack 14 is placed in the charging chamber 2, making it more convenient for users to take and place.

[0045] Two vertical spring pins 8 are installed on the inner wall of the lower end of the charging chamber 2 of the present invention. The end of the lifting plate 15 connected to the charging chamber 2 is provided with two strip grooves 9 parallel to the length direction of the lifting plate 15. The vertical spring pins 8 can pass through the strip grooves 9 and extend to the upper end surface of the lifting plate 15. Two sliders 12 are installed on the housing 13 of the fast-charging battery pack 14. The vertical spring pins 8 can abut against one end of the slider 12 to limit the movement of the fast-charging battery pack 14.

[0046] Specifically, when the fast-charging battery pack 14 is placed on the support platform 6, the slider 12 is located between the roller 5 and the enclosure 7. The roller 5 and the enclosure 7 can play a limiting and guiding role in the placement of the fast-charging battery pack 14, thereby preventing the fast-charging battery pack 14 from colliding with the side wall of the charging chamber 2, or getting stuck in the charging chamber 2 when placed at an angle for access.

[0047] Specifically, when the user places the fast-charging battery pack 14, the electric push rod 19 contracts, driving the lifting plate 15 to rotate downward until the lower end surface contacts the inner wall of the charging chamber 2. At this time, the lifting plate 15 is in a horizontal state, which is convenient for placement and connection with the charging cable 4;

[0048] The upper end surface of the vertical spring pin 8 of the present invention is provided with a transition slope 20 . When the fast-charging battery pack 14 is placed into the charging chamber 2 , the transition slope 20 can contact and slide relatively with the fast-charging battery pack 14 .

[0049] When the user places the fast-charging battery pack 14, the transition slope 20 of the vertical spring pin 8 first contacts one end of the rechargeable battery pack 14. As the rechargeable battery pack 14 continues to move into the charging chamber 2, the fast-charging battery pack 14 will continue to push the vertical spring pin 8, and the vertical spring pin 8 will be gradually compressed, and the top end will continue to move downward until it moves to a height that does not interfere with the movement of the fast-charging battery pack 14.

[0050] When the fast-charging battery pack 14 is completely placed inside the charging chamber 2, the vertical spring pin 8 is no longer subjected to the force of the fast-charging battery pack 14, so the top returns to its original height, resting against the end of the fast-charging battery pack 14 where the charging port 11 is set, restricting its movement.

[0051] Subsequently, the electric push rod 19 extends to control the lifting plate 15 to rotate upward to a certain angle and stop. At this time, the vertical spring pin 8 still presses against the fast-charging battery pack 14 to prevent the fast-charging battery pack 14 from sliding down and contacting the lower end surface of the charging chamber 2.

[0052] Specifically, when the user takes out the fast-charging battery pack 14, the electric push rod 19 extends again, controlling the lifting plate 15 to continue to rotate upward on the original basis until the upper end of the vertical spring pin 8 is immersed in the strip groove 9. The vertical spring pin 8 no longer limits the fast-charging battery pack 14. The fast-charging battery pack 14 slides down along the lifting plate 15 due to its own gravity and slides out of the charging chamber 2, making it easier for the user to take out the fast-charging battery pack 14.

[0053] A transition triangle block 3 is installed in the charging chamber 2 of the present invention. The transition triangle block 3 is located at one end of the lifting plate 15 close to the vertical spring pin 8. It can play a certain supporting role when the user places the fast-charging battery pack 14 into the charging chamber 2, and can also limit the rotation of the lifting plate 15 to prevent the lifting plate 15 from excessive rotation.

[0054] It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention. In addition, it should be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications and / or variations to the present invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims of this application.
