Description

Technical Field

[0001] The utility model relates to the technical field of power exchange cabinets, and in particular to an AI intelligent power exchange cabinet with a fingerprint module. Background Art

[0002] With the development of sharing technology, smart battery swap cabinets have emerged in various cities. Smart battery swap cabinets are also called shared battery swap cabinets, shared battery cabinets, battery swap stations, and battery exchange stations. As the name suggests, they are used for battery replacement. In the past, when people’s electric vehicles ran out of power, the first method they thought of was to find a place with a ground plug to connect the electric vehicle to a power source for charging. This traditional charging method is not only inconvenient, but also easily affects the work efficiency of takeaway boys and express delivery personnel. With the battery swap cabinet, when users use the battery swap cabinet, they only need to scan with their mobile phones to replace the fully charged battery with the dead battery. This not only saves users time and improves work efficiency, but is also convenient and quick to use.

[0003] However, the existing technology of unlocking the power exchange cabinet by scanning the code with a mobile phone has the following problems:

[0004] 1. For some user groups, such as food delivery boys, the delivery time is relatively tight. During the delivery process, they have to take out their mobile phones and jump from the food delivery page to the WeChat code scanning page. The operation is cumbersome and time-consuming, and the user experience is low.

[0005] 2. WeChat code scanning also has certain requirements for light. When the sun is glaring at noon or it is cloudy and rainy, WeChat code scanning will become very difficult, and users need to block the light or add light to successfully scan the code.

[0006] 3. They are heavily dependent on mobile phones. Without a mobile phone or when the mobile phone is out of power, they will not be able to unlock the battery replacement cabinet.

[0007] In order to solve the problem of battery replacement by scanning a code with a mobile phone, a battery swap cabinet with an NFC unlocking function is proposed in the prior art. The battery swap cabinet includes an NFC module for reading the NFC identification number in the user-defined card, and the main controller configures the unlocking and locking permissions of the battery swap cabinet for the NFC identification number. Although this solution does not rely on mobile phones, it requires users to carry access cards, bus cards, bracelets, etc. with NFC functions. These access cards, bus cards, and bracelets with NFC functions are not only easy to lose, but also increase the burden on users to carry. Utility Model Content

[0054] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0055] The technical solution of the utility model is further described in detail below through the accompanying drawings and embodiments.

[0056] See also Figure 1 and Figure 2 An AI smart power exchange cabinet with a fingerprint module provided by an embodiment of the utility model includes a power exchange cabinet body, and also includes a main control board 100 and a warehouse control board 200 arranged in the power exchange cabinet body, wherein the main control board 100 includes at least:

[0057] A main controller 101, and a communication module 103 and a fingerprint module 102 respectively connected to the main controller 101, and a solid state drive 104 connected to the fingerprint module 102; the communication module 103 is connected to a backend server 105;

[0058] The warehouse control board 200 is connected to the main controller 101 and is used to control the opening and closing of the battery compartment of the power exchange cabinet;

[0059] The fingerprint module 102 is used to read the user's fingerprint information and store it in the solid-state drive 104; the communication module 103 is used to send the user's fingerprint information to the background server 105, so that the background server 105 configures the authority to unlock and lock the power exchange cabinet for the fingerprint information, and synchronizes the authority to the main controller 101.

[0060] It is understandable that the technical solution provided by this embodiment enables the power exchange cabinet to recognize the user's fingerprint by adding a fingerprint module, a solid-state hard disk that stores fingerprint information, and replacing the main controller with a fingerprint recognition function. The user can quickly unlock and charge the cabinet through the fingerprint, without the need to carry access cards, bus cards, bracelets, etc. with NFC functions, which are not easy to lose and can be used immediately after swiping, thus improving the user experience. In addition, compared with mobile phone code scanning, it reduces the difficulty of operation and the dependence on mobile phones, and there is no need to consider the impact of light on code scanning. It has a wide range of application scenarios and a good user experience.

[0061] In addition, since the fingerprint information of registered users is stored in the solid-state drive, when the communication module is disconnected from the network and cannot establish a communication connection with the background server, the fingerprint information stored in the solid-state drive can also be used to ensure the normal use of the power swap cabinet by existing registered users, thereby improving the reliability of the power swap cabinet.

[0062] See also Figure 1 , the power exchange cabinet further includes:

[0063] Camera 1, connected to the main controller 101, arranged on the front panel of the power exchange cabinet, for collecting facial images and sending the facial images to the backend server 105;

[0064] And / or, the power exchange cabinet further includes:

[0065] The QR code module 2 is connected to the main controller 101 and is embedded on the front panel of the power exchange cabinet;

[0066] And / or, the power exchange cabinet further includes:

[0067] The display screen 3 is connected to the main controller 101 and is embedded in the front panel of the power exchange cabinet.

[0068] Preferably, the QR code module 2, fingerprint module 102 and display screen set 3 are arranged together, so that when the user is not a fingerprint registered user, he can also scan the QR code module to unlock and change the battery, ensuring the normal use of the battery exchange cabinet by the user. The display screen mainly displays the unlocking information, and provides the user with some guidance information on the operation steps when the user registers.

[0069] See also Figure 3 to Figure 7 In specific practice, the battery swap cabinet body is also provided with: a water tank 4 and a multi-layer battery compartment arranged above the water tank, and a through hole A for passing a spray pipe 5 is provided at the front opening of each battery compartment, and the through holes A of each layer of battery compartment are located on the same horizontal line; each layer of battery compartment reuses the same spray pipe 5, and the spray pipe 5 extends from the left side to the right side of the battery swap cabinet body, and a spray head 6 is provided at the opening position of each battery compartment.

[0070] Preferably, the water tank is provided with high-pressure pumps 7 whose number is equal to the number of battery compartment layers, one high-pressure pump 7 corresponds to one layer of battery compartment, and each high-pressure pump 7 is connected to the spray pipe 5 of the battery compartment of the corresponding layer through a hose.

[0071] See also Figure 3 and Figure 4 , each of the battery compartments is a cavity with one side open and surrounded by a left side plate, a right side plate, a top plate, a bottom plate and a back plate, and the compartment cover (not shown in the drawings) is arranged at the opening of the cavity;

[0072] The spray pipe 5 is arranged at the opening, one end of which is inserted through the upper end of the left side plate, and the other end is inserted through the upper end of the right side plate; the top plate is abutted between the spray pipe 5 and the back plate;

[0073] The spray head 6 is disposed on the spray pipe 5, and the water spray port of the spray head 6 faces the cavity. A drainage hole B is disposed at the connection between the back plate and the bottom plate.

[0074] It can be understood that the technical solution provided in this embodiment improves the water-cooled self-circulating fire-fighting pipeline for fire extinguishing in the battery compartment, including:

[0075] By arranging a sprinkler pipe at the opening of the battery compartment cavity, which is directly connected to a water source, the fire-fighting waterway can directly enter the battery compartment from the front of the battery compartment to extinguish the fire. Compared with the prior art in which a sprinkler head is arranged on the top of the battery compartment, water is drawn from the back of the battery compartment through a capillary tube from the main water supply pipe, which eliminates the tangled capillaries and greatly simplifies the structure of the battery compartment and the waterway design.

[0076] When multiple battery compartments are connected in series, the battery compartments on the same layer can reuse the same spray pipe. After water is passed through the spray pipe, water can be supplied to each battery compartment on the same layer. Compared with the prior art of supplying water to the spray head from the back of the battery exchange cabinet through multiple capillaries, the technical solution provided in this embodiment greatly simplifies the fire water supply line of the battery compartment and saves product costs.

[0077] Preferably, the power exchange cabinet further includes:

[0078] A drainage groove (not shown in the drawings) is provided on the back of each battery compartment and is attached to the water outlet direction of the drain port B;

[0079] The drainage pipes (not shown in the drawings) arranged on the left and right sides of the battery swap compartment are connected to the drainage groove, and the bottom of the drainage pipes is connected to the water tank 4.

[0080] It is understandable that if the fire-fighting water is stored in the battery compartment for a long time, and the battery swap cabinet works in a humid environment, the battery is prone to failure and short circuit. Therefore, the technical solution provided in this embodiment collects the water in the battery swap cabinet through the spray water collection pipeline, which can improve the safety and reliability of the battery swap cabinet.

[0081] See also Figure 4 and Figures 8A to 8D , a charger 8 for charging the battery compartment is provided on the back of each battery compartment;

[0082] The charger 8 includes a charging module 81, and a first water pipe 82 and a second water pipe 83 attached to the back of the charging module 81; both ends of the first water pipe 82 are provided with quick connectors 84 for connecting with the first water pipe of an adjacent charger; both ends of the second water pipe 83 are provided with quick connectors 84 for connecting with the second water pipe of an adjacent charger.

[0083] See also Fig. 9 After the first water pipe 82 on the back of the top charger is connected, one end is connected to the water tank 4 through the low-pressure water pump 9, and the other end is connected to the same-side port of the second water pipe 83 through a hose; the other end of the second water pipe 83 is connected to the same-side port of the first water pipe of the next layer through a hose;

[0084] One end of the second water pipe 83 on the back of the charger at the bottom layer is connected to the first water pipe 82 at the same layer through a hose, and the other end is directly connected to the water tank 4.

[0085] It can be understood that after the water in the water tank is pumped into the topmost battery compartment, the first water pipe and the second water pipe on the topmost layer will divert the water to the contact surface of the charger in the topmost battery compartment to cool down the charger in this layer of the battery compartment; then, the water that has cooled down the charger in the topmost battery compartment flows into the contact surface of the charger in the next-top battery compartment through the first water pipe and the second water pipe on the next-top layer to cool down the charger in the next-top battery compartment... and so on. Finally, the water flows back to the water tank and is pumped to the back of the topmost battery compartment by the circulating water pump again to achieve water-cooled circulation cooling.

[0086] Figures 8A to 8D , each of the charging modules is provided with a mounting foot 85 of a preset height at the bottom, and the mounting foot 85 is provided with a fastening hole for installing a fastener; after the charger is installed on the back of the battery compartment through the mounting foot 85, a space of a preset height is supported between the back of the charging module 81 and the back of the battery compartment;

[0087] The preset height is greater than or equal to the maximum value of the outer diameters of the first water pipe 82 and the second water pipe 83 .

[0088] It can be understood that the technical solution provided in this embodiment improves the water-cooled self-circulating cooling pipeline for cooling the charger in the existing battery swap cabinet, including:

[0089] Through clever improvements to the charger structure, the water-cooled self-circulating cooling pipeline for cooling the charger is directly set in the gap between the charger and the battery compartment. There is no need to lay out additional heat dissipation profile grooves to support the water circulation pipeline. This greatly optimizes the product structure and pipeline design, saves space inside the battery swap cabinet, and makes the ventilation and heat dissipation space inside the battery swap cabinet larger, further improving the safety and reliability of the product.

[0090] See also Figure 6 and 10In the space between the top of the power exchange cabinet and the uppermost battery compartment, there are provided a backup battery 10 and at least one smoke sensor 11, a temperature sensor (not shown in the drawings) and an AI detection camera 12; the AI ​​detection camera 12 is used to collect smoke and fire images in the power exchange cabinet, and send the collected images to the backend server 105;

[0091] and / or,

[0092] A cooling air conditioner 13 is provided in the space between the top of the power exchange cabinet and the uppermost battery compartment. The cooling air conditioner 13 is an air conditioner without an external unit and is used to cool the power exchange cabinet body.

[0093] It is understandable that the AI ​​detection camera is used to collect images of smoke and fire inside the battery swap cabinet and send the collected images to the background server. This can ensure that when the smoke sensor and temperature sensor fail, the background server staff can accurately know the situation on the battery swap cabinet site through the images sent back by the AI ​​detection camera, and promptly initiate emergency fire extinguishing, or notify nearby staff to go to the site for processing, thereby improving the reliability and safety of the battery swap cabinet.

[0094] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims. The terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. The term "plurality" refers to two or more, unless otherwise clearly defined.
