Description

Technical Field

[0001] This application relates to the technical field of mobile charging, and particularly to a mobile power cabinet machine. Background Art

[0002] At present, shared power bank cabinets are widely deployed in crowded places such as shopping malls, supermarkets, and restaurants, greatly facilitating people's charging needs. A shared power bank cabinet is an Internet of Things device that needs to interact with user terminals such as mobile phones through a network. Currently, shared power bank cabinets are generally connected through a mobile communication network, for example, through a 4G signal. The quality of the 4G signal depends to a large extent on the base station layout of the operator. In different regions, the base station layout of the operator is different. For example, in some regions, the signal of China Mobile may be better, while the signal of China Telecom is weak or even non-existent; in other regions, the signal of China Telecom may be better, while the signal of China Mobile is weak or even non-existent. Currently, the shared power bank cabinets can usually only connect to the signal provided by a single operator. When the signal provided by this operator in a certain area is weak or even non-existent, the network connection of the shared power bank cabinet using the signal provided by this operator is unstable or even unable to connect to the network, bringing great inconvenience to users.

[0003] In view of this, it is necessary to propose a new technical solution to overcome the deficiencies of the existing technology. Summary of the Utility Model

[0028] Please refer to Figures 1 to 3 As shown, this application provides a mobile power cabinet 100 that communicates through a mobile communication network to be able to interact with a user's handheld terminal and implement operations such as borrowing and returning mobile power supplies. The user's handheld terminal includes mobile phones, tablets, smart watches, etc. The mobile power cabinet 100 includes a communication module 10 for connecting to the mobile communication network. The communication module 10 includes a first SIM card module 1, a second SIM card module 2, and a switching module 3. Among them, the first SIM card module 1 and the second SIM card module 2 are adapted to connect to mobile communication networks provided by different operators, and the switching module 3 is configured to switch to connect to the mobile communication network provided by the other SIM card module when the first SIM card module 1 or the second SIM card module 2 cannot connect to the mobile communication network provided by its corresponding operator.

[0029] The mobile power cabinet 100 provided by this application has a dual SIM card module. The two SIM card modules are adapted to connect to the mobile communication networks provided by different operators. When one of the SIM card modules fails to connect to the mobile communication network provided by its corresponding operator, it can be switched to the other SIM card module to connect to the mobile communication network provided by its corresponding operator. In this way, it can adapt to network environments in various situations and has a stable network connection.

[0030] In China, the main operators providing mobile communication network services are China Mobile, China Unicom, and China Telecom. To use the mobile communication network services provided by different operators, corresponding SIM cards are required. In this embodiment, one of the first SIM card module 1 and the second SIM card module 2 is a mobile card, and the other is a telecom card or a Unicom card. In this way, in areas where the signal provided by China Mobile is poor, it can be switched to the telecom card or Unicom card to connect to the signal provided by China Telecom or China Unicom; in areas where the signal provided by China Telecom or China Unicom is poor, it can be switched to the mobile card to connect to the signal provided by China Mobile, so that the mobile power cabinet 100 has better network stability and reduces situations such as the inability to perform operations due to poor single network signal.

[0031] In this embodiment, the first SIM card module 1 and the second SIM card module 2 are configured in a dual-SIM single-standby mode. That is, when one of the SIM card modules is in the working state, the other SIM card module is in the closed state. Since the SIM card modules used on the mobile power cabinet 100 are mainly used to connect to the mobile network, as long as one of the two SIM card modules works, the above requirements can be met. Therefore, it is not necessary to keep both SIM card modules in the working state. Configuring the two SIM card modules in a dual-SIM single-standby mode can reduce power consumption. Of course, in other embodiments, the two SIM card modules can also be configured in a dual-SIM dual-standby mode.

[0032] Further, both the first SIM card module 1 and the second SIM card module 2 include a SIM card slot and a SIM card inserted into the SIM card slot. That is, the first SIM card module 1 includes a first SIM card and a first SIM card slot, and the second SIM card module 2 includes a second SIM card and a second SIM card slot. The network mode corresponding to each SIM card slot may be a SIM card adapted to only a single operator, or a SIM card capable of adapting to multiple operators. In this embodiment, the mobile communication network includes 3G, 4G, and 5G communication networks. The communication module 10 is a full-netcom 4G communication module, which includes two SIM card slots. The two SIM card slots are full-netcom card slots, that is, any SIM card slot can be adapted to a SIM card of any operator. It should be noted that a SIM card (Subscriber Identity Module) is an IC card used to identify a user's identity. It can be a pluggable independent card or an embedded one. For example, in some embodiments, the SIM card may be an eSIM card. The eSIM card is directly embedded in the device chip without a physical slot. The function of the eSIM card is the same as that of a common SIM card, supporting connecting to the Internet, making and receiving calls, sending text messages, etc. The communication module 10 described in this application including two SIM card modules should be understood as having at least two SIM card modules. The above embodiments are also described by taking two SIM card modules as an example. It can be understood that in other embodiments, the number of SIM card modules may be three or more. Another thing to note is that the full-netcom 4G communication module and the full-netcom card slot have been maturely applied on mobile phones, and this application will not elaborate on them.

[0033] Please refer to Figure 2 and Figure 3 as shown, where Figure 2 shows a scenario where the mobile power cabinet 100 is connected to the network provided by the first base station 5 through the first SIM card module 1. Figure 3The scenario where the mobile power supply cabinet 100 is connected to the network provided by the second base station 6 through the second SIM card module 2 is shown. The first base station 5 and the second base station 6 are base stations of different operators, which are used to provide mobile signals of different network systems or frequency bands. For example, the first base station 5 is a China Mobile base station, and the second base station 6 is a China Telecom base station. In one embodiment, the switching module 3 is configured to switch to the other SIM card module to connect to the mobile communication network when the first SIM card module 1 or the second SIM card module 2 fails to connect to the mobile communication network after attempting to connect no less than twice. Such a setting can avoid switching actions caused by accidental network connection failures. That is, in some cases, a SIM card module may fail to connect to the network due to accidental, short-term or instantaneous factors, and it can be connected after attempting to connect one or several more times. In this way, the switching frequency between the two SIM card modules can be reduced, the network connection waiting time can be reduced, and it is beneficial to maintain the stability of the network connection of the mobile power supply cabinet 100. When it still fails to connect to the network provided by the operator after attempting to connect twice or more times, it can be considered that there are problems that are difficult to overcome in a short time with the network provided by the operator, and then switch to connect to the network provided by another operator.

[0034] In some embodiments, the first SIM card module 1 and the second SIM card module 2 have different priorities, so that in some initial or default situations, the SIM card module with a higher priority is in the working state. In this embodiment, the priority of the first SIM card module 1 is higher than that of the second SIM card module 2. The switching module 3 is configured to switch the first SIM card module 1 to the working state and stop switching when both the first SIM card module 1 and the second SIM card module 2 cannot connect to the mobile communication network. Further, the switching module 3 is configured to switch the first SIM card module 1 to the working state and stop switching when the switching between the first SIM card module 1 and the second SIM card module 2 fails to connect to the mobile communication network no less than three times. Through no less than three switching operations, both the first SIM card module 1 and the second SIM card module 2 attempt to connect multiple times at different times to ensure a sufficiently full judgment of whether the networks provided by their corresponding operators are both unavailable. It should be noted that the switching module 3 should be understood that the communication module 10 can implement the switching function, and this switching function can specifically be implemented by the processor of the communication module 10 or components or circuits controlled by the processor, that is, the switching module 3 is a set that can implement the switching function and is not necessarily an independent entity.

[0035] The usage process of a specific embodiment is as follows: The program of a device such as a mobile power cabinet 100 will perform SIM card priority configuration and default to connect to the operator network of the first SIM card. If the operator network of the first SIM card is normal and the device can be used normally, the device will always use this network; if the operator network has an abnormality and causes the device to be unable to access the Internet normally, the device will switch to the operator network of the second SIM card after repeating three times and all attempts fail. If the operator network corresponding to the second SIM card is normal and the device can access the Internet normally, the device will always use this network; if the operator network corresponding to the second SIM card is abnormal and the device fails after repeating three times, the device will switch back to the operator network corresponding to the first SIM card; when the device fails after three switches, the device will switch to the first SIM card and stop switching. When the device is powered on / off or restarted again, the above process can be repeated once.

[0036] Furthermore, the mobile power cabinet 100 further includes an abnormality display module 20. The abnormality display module 20 is used to display network connection abnormality information when both the first SIM card module 1 and the second SIM card module 2 cannot connect to the mobile communication network. Setting the abnormality display module 20 can facilitate the user to know the network connection status of the mobile power cabinet 100 and avoid a very poor usage experience caused by the user's unclear situation and multiple unsuccessful attempts. The abnormality display module 20 can be a display screen or an indicator light, etc.

[0037] Please refer to Figure 4 As shown, it is a partial circuit diagram of the mobile power cabinet 100 related to communication. In this embodiment, the mobile power cabinet 100 includes a power supply circuit for supplying power to the communication module 10. There is an energy storage and filtering circuit between the power supply circuit and the communication module 10. The communication module 10 includes a module chip, a current limiting resistance circuit, and an anti-interference capacitor circuit. Specifically, the power supply circuit provides a voltage of +3.8V; capacitors C1 to C10 are connected in parallel to form an energy storage and filtering circuit, which can filter out the influence of power supply noise in different frequency bands on the module chip, enhance the power supply stability under large current loads, enhance the radio frequency performance, and ensure the communication effect of the device. In this embodiment, the module chip selects the EC801E-CN module of Quectel. Resistor R1 is a pull-up resistor for the DATA pin of the external SIM card; resistors R2 to R4 are current limiting resistors, which form a current limiting resistance circuit to prevent damage to the module caused by static electricity introduced when the SIM card is inserted. Filtering capacitors C11 to C13 form an anti-interference capacitor circuit, which is used to filter out communication interference between the external signal and the SIM card and the module chip.

[0038] The mobile power cabinet 100 provided by the present application can specifically be a shared power bank rental device or a battery swapping cabinet. A power bank is usually a device used to charge smart terminals such as mobile phones and tablets; a battery is usually a device used to supply power to electric bicycles, electric tricycles, or even electric vehicles. Both power banks and batteries are common mobile power sources.

[0039] From the description of the specific embodiments above, it can be seen that the mobile power cabinet 100 provided by the present application has a dual SIM card module. The two SIM card modules are suitable for connecting to mobile communication networks provided by different operators. When one SIM card module fails to connect to the mobile communication network provided by its corresponding operator, it switches to the other SIM card module to connect to the mobile communication network provided by its corresponding operator. In this way, it can adapt to network environments in various situations and has a stable network connection.

[0040] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0041] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
