Description

Technical Field

[0001] This application belongs to the technical field of mobile charging devices, and particularly relates to a mobile power supply and a rental device. Background Art

[0002] With the rapid development of technology, continuously updated mobile intelligent devices such as smart phones, smart wearable devices, tablet computers, and laptop computers are all dedicated to business or private communication, communication, shooting, and computing needs. As the functions of mobile intelligent devices become more and more, the battery life of mobile intelligent devices cannot meet the usage requirements, and often when going out, the batteries of mobile intelligent devices such as smart phones and tablet computers are out of power. At present, there are already a large number of shared mobile power supplies for charging mobile intelligent devices on the market, enabling users to meet the charging needs of mobile intelligent devices at any time without having to carry a mobile power supply by themselves.

[0003] Shared mobile power supplies are generally set on rental devices, and users take out the mobile power supply from the rental device to charge the mobile intelligent devices they carry themselves. The current shared mobile power supplies have a single function, only the charging function, and do not bring more added value to users. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide a mobile power supply and a rental device to solve the technical problem that the shared mobile power supply on the rental device in the prior art has a single function.

[0005] To achieve the above purpose, the technical solution adopted in this application is: to provide a mobile power supply, including:

[0006] A housing, provided with a paper loading slot, an output port, and a data connector for connecting to a mobile intelligent device;

[0007] A battery cell, arranged in the housing, and the battery cell is electrically connected to the data connector;

[0008] A printing mechanism, arranged in the housing, the printing mechanism includes a printing module and a paper feeding roller group, the printing module is electrically connected to the data connector, and the printing module is used to print the received data on printing paper; the paper feeding roller group is used to output the printing paper installed in the paper loading slot from the output port.

[0009] In this way, the mobile power supply not only has a battery cell for charging mobile intelligent devices, but also has a printing mechanism that can realize the printing function, so that the printing function is integrated on the mobile power supply, and users can print photos through the mobile power supply.

[0010] Improve the internal structure of the power bank. The battery cell and the printing module are arranged separately inside the housing to form a heat insulation space, and a heat insulation structure is also provided in the housing within the heat insulation space. This separates the heat generated when the battery cell and the printing module inside the power bank operate, thereby preventing the heat existing inside the housing from easily accumulating and causing the temperature to increase, effectively reducing the internal temperature of the power bank during operation.

[0011] Make an improvement to the heat insulation structure. The heat insulation structure is a protrusion provided in the heat insulation space. The protrusion extends along the length direction of the battery cell and blocks between the battery cell and the printing module, effectively preventing the heat generated when the battery cell and the printing module operate from accumulating with each other and avoiding the power bank from easily generating heat during operation.

[0012] In one embodiment, a cable storage groove corresponding to the position of the protrusion is formed on the outer surface of the housing. The data connector and its connecting wire are received in the cable storage groove. In this way, the protrusion serves as a heat insulation wall between the battery cell and the printing module inside the housing, and at the same time, the protrusion forms a cable storage groove for receiving the data connector and its connecting wire on the outer surface of the housing, effectively utilizing the available space on the housing to allow the data connector to be stored on the housing when not in use.

[0013] In one embodiment, the protrusion and the cable storage groove are in shape fit. The cable storage groove includes a straight groove and a receiving groove for receiving the data connector, and the shape of the receiving groove is adapted to the data connector. This allows the data connector and its connecting wire to be received in the cable storage groove, achieving a hidden storage design to keep the surface of the housing of the power bank flat and aesthetic.

[0014] In one embodiment, a rotating shaft is further provided in the housing within the cable storage groove. The connecting wire of the data connector is connected to the rotating shaft and can rotate on the housing around the rotating shaft, enabling the data connector and its connecting wire to extend from or be received in the cable storage groove on the housing. This allows the data connector and its connecting wire to rotate around the rotating shaft to achieve the opening or storage operation.

[0015] Make another improvement to the heat insulation structure. The heat insulation structure is a baffle made of heat insulation material, and the baffle stands between the printing module and the battery cell. In this way, the interior of the housing is divided into two chambers by the baffle. One chamber is used for arranging the battery cell, and the other chamber is used for arranging the printing module, so that the heat generated when the battery cell and the printing module work respectively is blocked, avoiding the heat from being superimposed and causing the power bank to easily generate heat.

[0016] Improve the internal structure of the mobile power supply. The printing mechanism further includes a bracket, and the printing module further includes a print head, which is arranged on the bracket; the paper feeding roller group is arranged on the bracket and is in position cooperation with the output port so as to output the printing paper while printing. Among them, a thermal print head can preferably be adopted for the print head so that the data on the printing paper can be quickly imaged.

[0017] In one embodiment, the housing further includes a push cover for covering the paper loading slot and slide rails on both side edges of the housing. Both side edges of the push cover are arranged on the slide rails and can move linearly along the slide rails. The user can push open the push cover to open the paper loading slot to replenish the printing paper for the mobile power supply.

[0018] This application also provides a rental device, including the mobile power supply described above. The rental device is provided with a plurality of charging slots for installing the mobile power supply, and the mobile power supply can be selectively inserted into the charging slots. This enables users to easily find rental devices outdoors and obtain mobile power supplies by renting to charge mobile intelligent devices in a timely manner; or enables users to use the printing function of the mobile power supply to print out the data stored in the mobile intelligent device, such as image data, at any time and anywhere, which is convenient for use.

[0019] In one embodiment, the rental device is further provided with a control panel, a paper bin for storing printing paper and its paper outlet. The control panel can communicate with the mobile intelligent device and control the opening and closing of the paper outlet. In this way, users can purchase printing paper through the rental device and replenish the printing paper for the mobile power supply, and conveniently use the printing function of the mobile power supply.

[0020] The beneficial effects of the mobile power supply and the rental device provided by this application are as follows: Compared with the prior art, on the mobile power supply of this application, there is both a storage battery cell for charging the mobile intelligent device and a printing mechanism capable of realizing the printing function. The housing has a paper loading slot for installing the printing paper. The printing module of the printing mechanism realizes data transmission with the externally connected mobile intelligent device through the data connector on the mobile power supply, and can print out the received printing data, such as image data or file data, etc., through the printing paper, and the paper feeding roller group outputs the printed printing paper, so that the printing function is integrated on the mobile power supply.

[0021] The mobile power supply of the present application can preferably be a shared mobile power supply set on a rental device. It is easy to find the rental device outdoors, making it easy for users to obtain the mobile power supply. Users can not only charge their mobile intelligent devices with the mobile power supply, but also utilize the printing function integrated on the mobile power supply to print out the data stored on the mobile intelligent device, such as photos, documents, etc., at any time and place, and immediately obtain the printed photos or documents, effectively improving the overall performance of the shared mobile power supply on the rental device and enhancing the user experience.

[0044] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0045] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0046] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings.

[0048] As the camera function on mobile intelligent devices becomes more and more popular, for example: generally, smartphones have cameras, allowing users to freeze precious moment pictures at any time; moreover, as the cameras on smartphones become more and more high-definition, when users need to print the photos taken with the mobile phone when going out, they can only find a printing shop specifically to print them out, and users cannot print photos by themselves anytime and anywhere.

[0049] Herein, the embodiments of the present application provide a new type of mobile power supply and its rental device, integrating a printing function on the mobile power supply. Users can charge and continue the battery life by renting the mobile power supply when outside, and can also print photos using the printing function of the mobile power supply, effectively solving the technical problem of the single function of the shared mobile power supply on traditional rental devices, and now a detailed description thereof will be given.

[0050] Please refer to Figure 1 、 Figure 2 and Figure 3 . On a rental device 100, there is a mobile power supply 200 provided by the embodiments of the present application. The mobile power supply 200 includes a housing 1, an electric core 2, and a printing mechanism.

[0051] Among them, please refer to Figure 3 and Figure 4 . A data connector 3 is provided on the housing 1. The data connector 3 is used to connect to mobile intelligent devices such as smartphones and tablets. The data connector 3 can preferably be a data interface such as a USB interface or a TYPE-C interface that can achieve charging. The specific interface type can be set according to the usage requirements and will not be specifically limited here.

[0052] The battery cell 2 is disposed within the housing 1, and the battery cell 2 is electrically connected to the data connector 3 inside the housing 1. In this way, when the mobile power supply 200 is connected to the mobile intelligent device through the data connector 3, the battery cell 2 can be used to charge the mobile intelligent device.

[0053] Please also refer to Figure 3 、 Figure 4 and Figure 5 , a paper loading slot 11 and an output port 12 are further provided on the housing 1, and the paper loading slot 11 is used to store printing paper. The printing mechanism is disposed within the housing 1, and the printing mechanism includes a printing module 4 and a paper feeding roller group 5. The printing module 4 is electrically connected to the data connector 3, and the printing module 4 is used to print the received data on the printing paper. The paper feeding roller group 5 is preferably disposed within the range of the paper loading slot 11, and the paper feeding roller group 5 is used to output the printing paper installed in the paper loading slot 11 from the output port 12.

[0054] In this way, the user can operate a mobile intelligent device such as a smart phone, a tablet computer, etc., and perform data transmission with the printing module 4 inside the mobile power supply 200 by connecting to the data connector 3. The printing module 4 is used to print the received data such as image data, etc. on the printing paper, and output the printed photo through the paper feeding roller group 5.

[0055] Compared with the prior art, for the mobile power supply 200 provided in the embodiment of the present application, on the mobile power supply 200 of the present application, there is both a storage battery cell 2 for charging the mobile intelligent device, and a printing mechanism capable of realizing the printing function. The housing 1 has a paper loading slot 11 for installing the printing paper. The printing module 4 of the printing mechanism realizes data transmission with an externally connected mobile intelligent device through the data connector 3 on the mobile power supply 200, and can print the received printing data such as image data or file data, etc. on the printing paper, and the paper feeding roller group 5 outputs the printed printing paper, so that the printing function is integrated on the mobile power supply 200.

[0056] The mobile power supply 200 of the present application can preferably be a shared mobile power supply 200 disposed on the rental device 100. It is easy to find the rental device 100 outside, making it easy for the user to obtain the mobile power supply 200. The user can not only charge the mobile intelligent device through the mobile power supply 200, but also use the printing function integrated on the mobile power supply 200 to print out the data stored on the mobile intelligent device such as photos, files, etc. at any time, and immediately obtain the printed photos or files, effectively improving the overall performance of the shared mobile power supply 200 on the rental device 100 and improving the user experience.

[0057] In an embodiment of the present application, please refer to Figure 6, inside the mobile power supply 200, the printing mechanism further includes a bracket 6, and the printing module further includes a print head (not shown in the figure), and the print head is arranged on the bracket 6. Among them, the print head can preferably adopt a thermal print head so that the data printed on the printing paper can be quickly imaged, allowing the user to quickly obtain the printed photo.

[0058] The paper feeding roller group 5 is arranged on the bracket 6 and is matched with the position of the output port 12 on the housing 1 so as to output the printing paper while printing. In this embodiment, as Figure 6 shown, the bracket 6 is horizontally arranged inside the housing 1 between the output port 12 and the paper loading slot 11. The paper feeding roller group 5 at least includes two rollers 51 and a driving mechanism 52 for driving the two rollers 51 to rotate. The two rollers 51 are simultaneously arranged on the bracket 6. The driving mechanism 52 can preferably be a driving combination of a driving motor and a transmission chain, so that the two rollers 51 can rotate synchronously, transfer the printing paper smoothly from the paper loading slot 11 to the bracket 6, let the print head print, and then output it from the output port 12 in front of the housing 1 for people to take away.

[0059] In another embodiment of the present application, please refer to Figure 6 , a wireless communication module 41 is preferably further arranged on the printing module 4. A mobile intelligent device such as a smart phone can perform wireless communication connection with the printing module 4 through the wireless communication module 41, such as Bluetooth communication connection, etc., so as to realize wireless data transmission and print out the photo, effectively increasing the data transmission methods between the mobile power supply 200 and the mobile intelligent device.

[0060] This means that in actual application, the mobile power supply 200 can charge a mobile intelligent device through the data connector 3, and another mobile intelligent device can realize data transmission with the printing module 4 on the mobile power supply 200 through wireless communication, and control the printing module 4 to print out the photo, allowing the user to flexibly use the charging function and printing function of the mobile power supply 200 and improve the use efficiency.

[0061] In an embodiment of the present application, please refer to Figure 7 , the housing 1 further includes a push cover 13 and a slide rail 14 for covering the paper loading slot 11. The slide rail 14 is located on the edges on both sides of the housing 1. The two edges of the push cover 13 are arranged on the slide rail 14 and can move linearly along the slide rail 14, specifically a straight-line motion. In this way, the user can push open the push cover 13 to open the paper loading slot 11 to replenish the printing paper for the mobile power supply 200.

[0062] In this embodiment, according to the volume of the mobile power supply 200, it is more suitable to preferably adopt 3-inch printing paper. The shape and size of the paper loading slot 11 on the housing 1 are adapted to the printing paper so that the printing paper can be neatly stored in layers in the paper loading slot 11 of the housing 1.

[0063] In practical applications, since the power bank 200 provided by the embodiments of the present application integrates a rechargeable battery cell 2 and a printing mechanism for implementing a printing function inside, there may be heat when the battery cell 2 is charging, and heat is also generated when the printing module of the printing mechanism operates. Moreover, limited by the overall volume of the power bank 200, the internal space of the housing 1 is limited, and the layout of the electrical components arranged inside the power bank 200 is relatively compact, so heat is likely to accumulate and stack up, making the power bank 200 prone to heat during actual use, which affects the user experience.

[0064] Therefore, in an embodiment of the present application, the internal heat insulation structure of the power bank 200 is optimized. Please refer to Figure 6 and Figure 8 . Inside the housing 1, the battery cell 2 and the printing module 4 are arranged separately from each other to form a heat insulation space M. An insulation structure located in the heat insulation space M is also provided inside the housing 1, so that the heat generated when the battery cell 2 and the printing module 4 operate is separated, thereby reducing the easy accumulation of heat inside the housing 1 resulting in an increase in temperature, effectively reducing the internal temperature of the power bank 200 during operation, and avoiding the power bank 200 from being prone to heat during actual use.

[0065] For the specific form of the insulation structure, it includes but is not limited to the following forms:

[0066] In an embodiment of the present application, please refer to Figure 6 and Figure 8 . The insulation structure is a protrusion 7 arranged in the heat insulation space M. The protrusion 7 extends along the length direction of the battery cell 2 and is blocked between the battery cell 2 and the printing module 4.

[0067] In this embodiment, as shown in Figure 6 , the protrusion 7 can preferably be a rectangular strip extending along the length direction of the battery cell 2, and the protrusion 7 is horizontally blocked between the battery cell 2 and the printing module 4. In this way, the length, width and height of the protrusion 7 are used to form a blocking wall, so as to form a blocking distance and a blocking wall between the battery cell 2 and the printing module 4, effectively blocking the mutual accumulation of heat generated when the battery cell 2 and the printing module 4 operate, and avoiding the power bank 200 from being prone to heat during operation.

[0068] In order to further utilize the available space on the housing 1, a hidden storage design is made for the data connector 3 and its connecting wire 31. Please refer to Figure 8 , Figure 9 and Figure 10 . A wire hiding groove 15 corresponding to the position of the above protrusion 7 is opened on the outer surface of the housing 1, and the data connector 3 and its connecting wire 31 are housed in the wire hiding groove 15.

[0069] Thus, the protruding structure 7 on the housing 1 serves both as a heat insulation wall between the battery cell 2 and the printing module 4 inside the housing 1 and forms a cable storage groove 15 on the outer surface of the housing 1 for accommodating the data connector 3 and its connecting wire 31, effectively utilizing the available space on the housing 1 to allow the data connector 3 to be accommodated on the housing 1 when not in use.

[0070] For the specific structure of the cable storage groove 15, in the embodiments of the present application, please refer to Figure 8 , Figure 9 and Figure 10 together. The protruding structure 7 is in shape fit with the cable storage groove 15. The cable storage groove 15 includes a straight groove 151 and a receiving groove 152 for receiving the data connector 3. The receiving groove 152 is connected to the straight groove 151, and the shape of the receiving groove 152 is adapted to the data connector 3.

[0071] In this embodiment, the data connector 3 is a rectangular head with a USB interface or a TYPE-C interface at its end. The receiving groove 152 in the cable storage groove 15 is a rectangular groove with a length and width not less than that of the rectangular head, so that the data connector 3 can be integrally embedded in the receiving groove 152. At the same time, the connecting wire 31 integrally connected to the data connector 3 can also be embedded in the straight groove 151 along the way.

[0072] Thus, the data connector 3 and its connecting wire 31 are both accommodated in the cable storage groove 15, realizing a hidden storage design, so that the surface of the housing 1 of the mobile power supply 200 remains flat and aesthetic.

[0073] Preferably, in this embodiment, as Figure 10 shown, a rotating shaft 16 is further provided on the housing 1 inside the cable storage groove 15. The connecting wire 31 on the data connector 3 is connected to the rotating shaft 16 and can rotate on the housing 1 with the rotating shaft 16, so that the data connector 3 and its connecting wire 31 can extend from the housing 1 or be accommodated in the cable storage groove 15.

[0074] Specifically, the connecting wire 31 can preferably adopt a cable coated with a soft rubber strip, so that the soft rubber blocks foreign objects or water from directly reaching the cable, thereby improving the protection effect on the cable. At the same time, the connecting wire has a bending and deforming function, which is beneficial to adapting to the connection posture with the mobile intelligent device and improving the applicability of the connecting wire. The end of this soft rubber strip is installed and connected to the rotating shaft 16, so that the entire connecting wire 31 and the data connector 3 can rotate around the rotating shaft 16 to realize the opening or storage operation.

[0075] In other embodiments (not shown in the figure), a structure similar to a tape measure (not shown in the figure) can also be provided in the cable storage groove 15 of the housing 1. The connecting wire 31 is made of a flexible material, so that the connecting wire 31 can be wound up like a tape measure. When in use, a person can also pull out the connecting wire 31 by picking up the data connector 3, which is convenient for use.

[0076] For the specific form of the heat insulation structure, in another embodiment of the present application (not shown in the figure), the heat insulation structure may also preferably be a baffle made of heat insulation material (not shown in the figure), and the baffle stands upright between the printing module 4 and the battery cell 2.

[0077] Wherein, the upper and lower ends of the baffle are respectively connected to the top wall and the bottom wall of the housing 1. Specifically, the upper end of the baffle is connected to the bottom of the paper loading slot 11, and the lower end of the baffle is connected to the bottom surface wall of the housing 1.

[0078] In this way, the interior of the housing 1 is separated into two chambers by the baffle. One chamber is used to arrange the battery cell 2, and the other chamber is used to arrange the printing module 4, so that the heat generated by the battery cell 2 and the printing module 4 during their respective operations can be blocked, avoiding heat accumulation, and effectively reducing the temperature of the mobile power supply 200 during operation.

[0079] Please refer to Figure 11 , the embodiment of the present application further provides a rental device 100. The rental device 100 is provided with a plurality of charging slots 101 for installing the mobile power supply 200 of the present application, and the mobile power supply 200 of the present application can be selectively inserted into the corresponding charging slots 101.

[0080] The setting scenario of the rental device 100 is not limited. It can be set in scenarios such as dining cafes, entertainment venues, arcades, hotels, office places, shopping malls, airports, libraries, scenic spots, etc., so that users can easily find the rental device 100 outside and obtain the mobile power supply 200 by renting it to charge the mobile intelligent device in time; or, users can use the printing function of the mobile power supply 200 to print out the data stored in the mobile intelligent device, such as image data, etc., at any time for convenient use.

[0081] In the embodiment of the present application, please refer to Figure 11 , the rental device 100 is further provided with a control panel 102, a paper bin for storing printing paper (not shown in the figure) and its paper outlet 103.

[0082] Wherein, the control panel 102 is arranged on the surface of the rental device 100 facing the user. The control panel 102 may preferably include a screen part and a control part. Users can obtain rental information through the screen part or control the rental device 100 to unlock the corresponding charging slot 101 to obtain the mobile power supply 200.

[0083] The control panel 102 can also be communicatively connected to the mobile intelligent device and control the opening and closing of the paper outlet 103. Users can purchase printing paper through the rental device 100, thereby replenishing the printing paper for the mobile power supply 200 and conveniently using the printing function of the mobile power supply 200.

[0084] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
