Description

Technical Field

[0001] The present application relates to the technical field of shared charging, and provides a combined shared charging device. Background Art

[0002] At present, with the rapid development of mobile electronic products, the problem of outdoor battery life faces great challenges, and the shared charging devices distributed on the streets, shopping malls and other places well solve this problem.

[0003] The shared charging device contains multiple power banks. Users borrow the power banks by scanning the code to pay the deposit and fees, and return them after use. The shared charging device is purchased by the placement merchants from the manufacturer and placed in various areas.

[0004] At this stage, the shared charging devices are all delivered after being integrally manufactured, with the same configured and rated number of power banks. However, according to the different passenger flows in the placement areas, the required number of power banks is different. Therefore, it is necessary for the placement merchants to adjust the placement quantity of the shared charging devices between different placement areas according to the revenue situation, etc. In addition, there may be a problem that there is a demand for renting power banks in some areas, but the rental frequency is low. At this time, the adjustment requirements of the placement merchants cannot be met, and the idle of the power banks causes the operating cost to increase.

[0005] Therefore, the problem with the shared charging device is that the overall delivery of the shared charging device cannot meet the refined adjustment requirements of the placement merchants, resulting in an increase in operating costs in some placement areas due to insufficient rental frequency. For the manufacturer, customizing according to the requirements of the placement manufacturer will lead to the repetition of design work and mold opening work, and thus increase the design cost and manufacturing cost.

[0059] In order to illustrate the technical solutions described in the present application, the following will be described in detail with reference to specific accompanying drawings and embodiments.

[0060] Please refer to Figure 1 , Figure 3 and Figure 5 As shown, the embodiment of the present application first provides a combined shared charging device 100, including a working cabinet assembly 8 and a main control cabinet 9; wherein, as Figure 4 and Figure 5 shown, the working cabinet assembly 8 includes a working cabinet for splicing with the main control cabinet 9, or, as Figure 1 and Figure 3 shown, the working cabinet assembly 8 includes a plurality of working cabinets, and after the plurality of working cabinets are spliced in a certain manner, they are then spliced with the main control cabinet 9.

[0061] As Figure 5 and Figure 6 shown, in one embodiment, the working cabinet assembly 8 includes a working cabinet defined as the first working cabinet 7. Please refer to Figure 9 and Figure 10As shown, the first working cabinet 7 includes a first housing 71, a first circuit board 72 disposed within the first housing 71, and a plurality of rentable power banks 4 disposed within the first housing 71. Each power bank 4 is electrically connected to the first circuit board 72. The first circuit board 72 is provided with a first connection terminal 721 and a second connection terminal 722. Among them, the first housing 71 is provided with a first through hole 7120 for exposing the first connection terminal 721; the second connection terminal 722 is used to access an external power source.

[0062] As Figure 2 and Figure 4 shown, in one embodiment, the working cabinet assembly 8 includes a plurality of working cabinets, which are respectively defined as a first working cabinet 7 and at least one second working cabinet 6; the first working cabinet 7 is as described above; as Figure 11 and Figure 12 shown, the second working cabinet 6 includes a second housing 61, a second circuit board 62 disposed within the second housing 61, and a plurality of rentable power banks 4 disposed within the second housing 61. Each power bank 4 is electrically connected to the second circuit board 62. The second circuit board 62 is provided with a third connection terminal 621 and a fourth connection terminal 622. The second housing 61 is provided with a third through hole 6120 allowing the third connection terminal 621 to be exposed and a fourth through hole 6110 allowing the fourth connection terminal 622 to be exposed.

[0063] As Figure 7 and Figure 8 shown, the main control cabinet 9 includes a third housing 91 and a main control circuit board 92 disposed within the third housing 91. The main control circuit board 92 is provided with a fifth connection terminal 921. The third housing 91 is provided with a fifth through hole 9110 allowing the fifth connection terminal 921 to be exposed.

[0064] Then, the combined shared charging device 100 is assembled as follows:

[0065] Please refer to Figure 5 and Figure 6 shown, the working cabinet assembly 8 includes one working cabinet. The first working cabinet 7 and the main control cabinet 9 are spliced with each other. The first connection terminal 721 of the first working cabinet 7 is docked and connected with the fifth connection terminal 921 of the main control cabinet 9. In this way, both the main control circuit board 92 and the second circuit board 62 are connected to an external power source.

[0066] Or, refer to Figure 2 and Figure 4As shown, the working cabinet assembly 8 includes a first working cabinet 7 and at least one second working cabinet 6. Taking one second working cabinet 6 as an example, the first connection terminal 721 of the first working cabinet 7 is docked and connected with the fourth connection terminal 622 of the second working cabinet 6, and the third connection terminal 621 of the second working cabinet 6 is docked and connected with the fifth connection terminal 921 of the main control cabinet 9. In this way, the main control circuit board 92, the second circuit board 62, and the first circuit board 72 are all connected to the external power supply.

[0067] Then, at least one second working cabinet 6 can continue to be spliced between the first working cabinet 7 and the second working cabinet 6.

[0068] In this embodiment, the main control circuit board 92, the second circuit board 62, and the first circuit board 72 are all connected to the external power supply and work normally. The main control circuit board 92 is used to send control signals to the first circuit board 72 and the second circuit board 62. For example, the main control circuit board 92 sends a control signal to the first circuit board 72, and the first circuit board 72 drives the power bank 4 to pop out by controlling the driving mechanism 21 in the first housing 71. The main control circuit board 92 sends a control signal to the second circuit board 62, and the second circuit board 62 drives the power bank 4 to pop out by controlling the driving mechanism 21 in the second housing 61.

[0069] The combined shared charging device 100 provided by the embodiment of the present application is divided into a main control cabinet 9 and at least one working cabinet. The main control cabinet 9 and the working cabinet are electrically connected by relying on the exposed connection terminals. A small number of power banks 4 can be set in each working cabinet. In this way, the placing merchant can select an appropriate number of working cabinets for combined use, which is convenient for differential configuration of the rentable power banks 4 between different placing areas, ensuring that the number of rentable power banks 4 in each placing area adapts to the market demand and reducing the operation cost. In particular, for the manufacturer, only the main control cabinet 9 and the working cabinet need to be designed and manufactured, reducing design costs, multiple mold opening costs, etc., and generally reducing the production cost, which is beneficial to large-scale production and promotion.

[0070] In the embodiment of the present application, the splicing method between the working cabinets and between the working cabinet and the main control cabinet 9 is not limited. For example, refer to Figure 1 and Figure 3 As shown, they are spliced in a stacked manner in the vertical direction, with the main control cabinet 9 at the topmost and the first working cabinet 7 at the bottommost; for example, they can be spliced side by side in the horizontal direction, with the main control cabinet 9 and the first working cabinet 7 at the two outermost ends; or for another example, the main control cabinet 9 and the working cabinet are stacked along a broken line direction, etc., to adapt to the installation scenario of the combined shared charging device 100, etc.

[0071] In the embodiment and the drawings of the present application, the first working cabinet 7, the second working cabinet 6, and the main control cabinet 9 are sequentially stacked upward as an example for illustration.

[0072] Accordingly, the first connection terminal 721 is located at the upper end of the first housing 71, and the second connection terminal 722 can be located at a lower position within the first housing 71.

[0073] The third connection terminal 621 can be located at the upper end of the second housing 61, and the fourth connection terminal 622 can be located at the lower end of the second housing 61.

[0074] The fifth connection terminal 921 can be located at the lower end of the third housing 91.

[0075] It can be understood that between the first working cabinet 7 and the second working cabinet 6, except that the second connection terminal 722 and the fourth connection terminal 622 can be designed not to be completely the same, other parts can be designed to be the same as much as possible to facilitate splicing and mass processing. For example, the second connection terminal 722 is used to directly connect to an external power supply. Therefore, it can be relatively hidden within the first housing 71 and connected to the external power supply through the power cord 5 extending out of the first housing 71, such as Figure 9 and Figure 10 . The hole structure reserved on the first housing 71 does not have to be exactly the same as the fourth through hole 6110. Refer to Figure 9 and Figure 10 shown. The second through hole 7110 on the first housing 71 is configured to allow the power cord 5 to pass through, and its shape is preferably adapted to the connection between the power cord 5 and the first connection terminal 721.

[0076] In addition, it can be understood that on the basis of not affecting the splicing of the first working cabinet 7 and the second working cabinet 6, some differences in the partial structure and / or appearance of the two are also allowed.

[0077] Each second working cabinet 6 can be exactly the same to ensure infinite splicing and electrical connection. It can also be understood that on the basis of not affecting the mutual splicing between the second working cabinets 6, some differences in the structure and / or appearance between the second working cabinets 6 are also allowed.

[0078] In the main control cabinet 9, according to needs, one or more power banks 4 (not shown) can be set, and it is also possible not to set them. In an alternative embodiment, as Figure 7 and Figure 8 shown, no rentable power bank 4 is set in the main control cabinet 9. At this time, the main control cabinet 9 mainly functions to control each working cabinet. Therefore, there can be a greater design space in its shape, appearance, and other functions.

[0079] For example, a main power button (not shown) can be set on the main control cabinet 9, which is electrically connected to the main control circuit board 92 and used to turn on or off the combined shared charging device 100 and the external power supply with one key. Also, information of the manufacturer, scanning code information, usage instructions can be set on the surface of the main control cabinet 9, and even advertisements can be printed on it.

[0080] In one example, referring to Figure 9 and Figure 10 as shown, the main control cabinet 9 further includes a display screen 96 disposed on the first housing 71. The display screen 96 is electrically connected to the main control circuit board 92, and presents relevant information or interacts with the user through electronic display means.

[0081] Please refer to Figure 9 、 Figure 10 、 Figure 11 and Figure 12 as shown, battery compartments 22 are provided in both the first working cabinet 7 and the second working cabinet 6. A battery compartment cover 23 for closing the battery compartment 22 is provided on the first housing 71, and a battery compartment cover 23 for closing the battery compartment 22 is provided on the second housing 61. The power bank 4 is disposed in the battery compartment 22. The driving mechanisms 21 (such as motors, etc.) in the first housing 71 and the second housing 61 are respectively operated according to the control signals of the first circuit board 72 and the second circuit board 62 to eject the power bank 4.

[0082] As Figure 9 and Figure 10 shown, the first housing 71 includes a first bottom plate 711, a first top plate 712 and a first middle shell 713, and the three together define a first cavity (not shown). The power bank 4, the first circuit board 72, etc. are disposed in the first cavity. At most one of the first bottom plate 711 and the first top plate 712 can be optionally designed to be integrally formed with or non-detachably connected to the first middle shell 713, that is, at least one of the first bottom plate 711 and the first top plate 712 can be optionally made separately from the first middle shell 713 and detachably connected. Refer to Figure 9 and Figure 10 for facilitating the processing and manufacturing of the first housing 71 and the assembly of the first circuit board 72, the power bank 4, etc. in the first cavity. A first through hole 7120 is provided on the first top plate 712.

[0083] Refer to Figure 11 and Figure 12 as shown, the second housing 61 includes a second bottom plate 611, a second top plate 612 and a second middle shell 613, and the three together define a second cavity (not shown); the power bank 4, the second circuit board 62, etc. are disposed in the second cavity. At least one of the second bottom plate 611 and the second top plate 612 is designed to be separately manufactured from the second middle shell 613 and detachably connected. A third through hole 6120 is provided on the second top plate 612, and a fourth through hole 6110 is provided on the second bottom plate 611.

[0084] As Figure 7 and Figure 8As shown, the third housing 91 includes a third top plate 912, a third bottom plate 911, and a third middle housing 913. The three together define a third cavity (not shown), and the main control circuit board 92 and the like are disposed in the third cavity. A fifth through hole 9110 is provided on the third bottom plate 911. At least one of the third bottom plate 911 and the third top plate 912, optionally the third bottom plate 911, is separately manufactured from the third middle housing 913 and is detachably connected thereto.

[0085] In one embodiment, the fifth through hole 9110 on the third bottom plate 911 corresponds to the fourth through hole 6110 on the second bottom plate 611, which means that they are aligned in the splicing direction of the main control cabinet 9 and the second working cabinet 6. The purpose of such a setting is that the third bottom plate 911 and the second bottom plate 611 have the same structure and can be manufactured using the same design drawing or based on the same mold.

[0086] In one embodiment, the first through hole 7120 on the first top plate 712 corresponds to the third through hole 6120 on the second top plate 612, which means that they are aligned in the splicing direction of the first working cabinet 7 and the second working cabinet 6. The purpose of such a setting is that the first top plate 712 and the second top plate 612 have the same structure and can be manufactured using the same design drawing or based on the same mold.

[0087] Please refer to Figure 7 and Figure 8 As shown, in one embodiment, the combined shared charging device 100 further includes a communication module 95. The communication module 95 includes a mounting component 951 and a communication card 952. The communication module 95 can be disposed in the first working cabinet 7 or the main control cabinet 9; in the case of including the second working cabinet 6, it is also possible to dispose the communication module 95 in the second working cabinet 6.

[0088] The communication card 952 is communicatively connected to the main control circuit board 92 and is remotely communicatively connected to the background server for signal interaction between the main control circuit board 92 and the background server. This includes transmitting the information of the main control circuit board 92 to the background server and transmitting the control information of the background server to the main control circuit board 92, and the main control circuit board 92 further controls each working cabinet to perform corresponding actions.

[0089] In one embodiment, the mounting component 951 of the communication module 95 is disposed on the main control cabinet 9 to facilitate direct connection to the main control circuit board 92. Specifically, please refer to Figure 7 and Figure 8 As shown, a sixth through hole 9111 corresponding to the mounting component 951 is provided on the third housing 91 to allow the communication card 952 to be detachably mounted on the mounting component 951 via the sixth through hole 9111. The purpose of such a setting is to facilitate the installation, disassembly, and replacement of the communication card 952.

[0090] Optionally, as shown in Figure 7 and Figure 8 shown, the sixth through hole 9111 is provided on the third bottom plate 911. The purpose of this setting is that after the main control cabinet 9 is spliced with the working cabinet, the communication card 952 is not visible from the outside, realizing the hiding and protection of the communication module 95.

[0091] On this basis, a hole structure aligned with the sixth through hole 9111 may be provided on the second bottom plate 611, so that the structures of the second bottom plate 611 and the third bottom plate 911 are the same and can be manufactured based on the same mold.

[0092] In one embodiment, the first connection terminal 721 protrudes from the first top plate 712 and / or the fourth connection terminal 622 protrudes from the second bottom plate 611, and the first connection terminal 721 and the fourth connection terminal 622 are electrically connected in an inserted manner, which is beneficial to improving the reliability of the electrical connection.

[0093] Similarly, in one embodiment, the third connection terminal 621 protrudes from the second top plate 612, and / or the fifth connection terminal 921 protrudes from the third bottom plate 911, and the third connection terminal 621 and the fifth connection terminal 921 are electrically connected in an inserted manner, which is beneficial to improving the reliability of the electrical connection.

[0094] Other examples are not listed one by one. That is to say, between two mutually connected connection terminals, at least one connection terminal is designed to protrude so as to facilitate the insertion of these two connection terminals.

[0095] Among them, optionally, when the first connection terminal 721 protrudes, the third connection terminal 621 is also designed to protrude; when the fourth connection terminal 622 protrudes, the fifth connection terminal 921 is also designed to protrude.

[0096] In one embodiment, the first connection terminal 721, the third connection terminal 621, the fourth connection terminal 622, and the fifth connection terminal 921 are all blade battery holders.

[0097] In order to ensure that the working cabinets can be quickly positioned and stably spliced with each other and between the working cabinet and the main control cabinet 9, in one example, the first working cabinet 7 and the second working cabinet 6, between the second working cabinet 6 and the second working cabinet 6, and between the second working cabinet 6 and the main control cabinet 9 are positioned by means of concave-convex cooperation. For example, please refer to Figure 7 and Figure 8 shown, a positioning structure 11 is provided on the third bottom plate 911, as shown in Figure 9 and Figure 11 shown, a matching structure 12 adapted thereto is provided on the first top plate 712 and / or the second top plate 612; as shown in Figure 11 and Figure 12As shown, a positioning structure 11 is provided on the second bottom plate 611, and a mating structure 12 adapted thereto is provided on the first top plate 712 and / or the second top plate 612.

[0098] Optionally, the positioning structures 11 on the first top plate 712, the second top plate 612, the second bottom plate 611 and the third bottom plate 911 are provided in multiple numbers, for example, two or three, to further improve the alignment accuracy and splicing stability.

[0099] The positioning structure 11 is one of a groove and a protrusion, and the mating structure 12 is the other of a groove and a protrusion.

[0100] Please refer to Figure 7 and Figure 8 As shown, in one embodiment, in the combined shared charging device 100, a backup battery 3 is further included. The backup battery 3 can be arranged in at least one of the first working cabinet 7, the second working cabinet 6 and the main control cabinet 9 and is connected to the corresponding circuit boards therein. For example, it is arranged in the first working cabinet 7 and connected to the first circuit board 72, or arranged in the second working cabinet 6 and connected to the second circuit board 62, and arranged in the main control cabinet 9 and connected to the main control circuit board 92.

[0101] When the first circuit board 72, the second circuit board 62 and the main control circuit board 92 are connected to an external power supply, the backup battery 3 is charged, and the backup battery 3 stores electric energy. When the external power supply is turned off, such as in a power outage, the backup battery 3 can in turn supply electric energy to the first circuit board 72, the second circuit board 62 and the main control circuit board 92 to maintain at least partial normal functions of the combined shared charging device 100.

[0102] For example, to maintain the normal communication between the communication module 95 and the background server. When the user returns the charging treasure 4, the background server can transmit the information of the returned charging treasure 4 to the background server and perform deduction settlement, etc.

[0103] For example, to maintain the normal operation of the driving mechanism 21 in the working cabinet, allowing the user to normally rent the charging treasure 4. Of course, in an alternative embodiment, in order to reduce the power consumption of the backup battery 3, the connection between the driving mechanism 21 and the first circuit board 72 and the second circuit board 62 may not be connected, that is, at this time, the user is not allowed to rent the charging treasure 4.

[0104] In an alternative embodiment, the backup battery 3 is only arranged in the main control cabinet 9 and is electrically connected to the main control circuit board 92.

[0105] As Figure 7 shown, in one embodiment, a plurality of limiting convex plates 25 are provided on the third bottom plate 911. The plurality of limiting convex plates 25 continuously enclose or intermittently enclose and define an accommodation space 250. The backup battery 3 is located in the accommodation space 250.

[0106] Optionally, the periphery of the backup battery 3 abuts against the inner side surface of each limiting convex plate 25 to maintain fixation.

[0107] It can be understood that limiting convex plates 25 and accommodation spaces 250 can also be provided on the second bottom plate 611, and the backup battery 3 can be provided or not.

[0108] Please refer to Figure 7 、 Figure 9 and Figure 11 As shown, chips are provided on the first circuit board 72, the second circuit board 62, and the main control circuit board 92, which can be respectively defined as the first chip 74, the second chip 64, and the third chip 94. Identification information corresponding to the first locker 7, the second locker 6, and the main control cabinet 9 is stored in each chip, such as an ID number represented by a digit. When the first locker 7, the second locker 6, and the main control circuit board 92 are powered on and connected to the background server, the background server will read the stored information in each chip through the main control circuit board 92. When the stored information of each chip belongs to the information of the same placement merchant, at this time, the first locker 7, the second locker 6, and the main control cabinet 9 are successfully paired, and the first locker 7, the second locker 6, and the main control cabinet 9 can all work normally. When the stored information of each chip does not belong to the information of the same placement merchant, for example, when the stored information on the chip of the second locker 6 does not belong to the same placement merchant as the stored information on the chip of the main control cabinet 9, the background server controls the first locker 7 to lock. Here, the locking means that the user cannot rent the power bank 4 from the second locker 6. For example, the main control circuit board 92 controls the second circuit board 62 to stop the driving mechanism 21 in the second housing 61 from working, and the power bank 4 cannot pop out. To ensure the rights and interests of users, at this time, the user can be allowed to return the power bank 4 to the second locker 6 and settle the fees.

[0109] In one embodiment, the combined shared charging device 100 further includes a connecting member (not shown), and the connecting member is used to detachably connect the first locker 7 and the second locker 6, the second locker 6 and the second locker 6, and the second locker 6 and the main control cabinet 9, so as to further improve the stability of the combined shared charging device 100, and at the same time, allow adjustment between the lockers.

[0110] Specifically, a first connecting portion (not shown) is provided on the first housing 71, and a second connecting portion (not shown) is provided on the second housing 61. The connecting member detachably connects the first connecting portion and the second connecting portion, thereby realizing the detachable connection between the first housing 71 and the second housing 61.

[0111] Similarly, a first connection part and a second connection part may be respectively provided on the second housing 61. The second connection part can be used to connect with the first connection part provided on the third housing 91, and can also be used to connect with the first connection part on an adjacent second housing 61.

[0112] Optionally, one of the above-mentioned first connection part and second connection part is a lug with a mounting hole, and the other is a threaded hole. The connecting member can be a bolt, and the bolt meshes into the threaded hole after passing through the mounting hole on the lug.

[0113] In other alternative embodiments, the first connection part and the second connection part can have other setting forms. For example, both the first connection part and the second connection part are lugs with mounting holes, the connecting member is a bolt, or the connecting member is a buckle, and the first connection part and the second connection part are lugs, etc. More forms will not be exemplified one by one.

[0114] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
