[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model will be given.
[0035] The present invention provides a power bank cabinet 100. Figures 1-6 As shown, the power bank cabinet 100 includes a shell 110, a charging terminal and a main control module 120. The shell 110 has an installation cavity and a charging compartment 111. The charging compartment 111 is used to accommodate the power bank. The installation cavity is arranged inside the shell 110. The shell 110 is provided with an insertion port 112 on the outside. The insertion port 112 is connected to the installation cavity. The insertion port 112 is used for the expansion module 200 to be inserted. The charging terminal is at least partially arranged in the charging compartment to charge the power bank. The main control module 120 is installed in the installation cavity. A first electrical connection structure 121 is provided on the main control module 120, and a second electrical connection structure 210 is provided on the expansion module 200. The first electrical connection structure 121 is used to connect with the second electrical connection structure 210 so that the main control module 120 can be electrically connected to the expansion module 200.
[0036] By implementing this embodiment, the power bank cabinet 100 has a structure with expandable functions, and the functions of the power bank cabinet 100 can be expanded according to needs by cooperating with the expansion module 200. Compared with the method of requiring the entire power bank cabinet 100 to be replaced, the cost can be effectively reduced. Specifically, the outside of the shell 110 is provided with an insertion port 112 that connects to the internal mounting cavity of the shell 110. The insertion port 112 can be used for the expansion module 200 to be inserted. The main control module 120 in the mounting cavity is provided with a first electrical connection structure 121. After the expansion module 200 is inserted into the insertion port 112, the first electrical connection structure 121 can be connected to the second electrical connection structure 210 on the expansion module 200, so that the main control module 120 and the expansion module 200 are electrically connected, so that the expansion module 200 can be used to expand the functions of the power bank cabinet 100.
[0037] It should be noted that there are many specific embodiments of the expansion module 200, as long as it can expand the functions of the power bank cabinet 100. This embodiment is not limited here. Three embodiments are listed below for reference.
[0038] In embodiment one, the expansion module 200 includes a WIFI receiving module. Since the power bank cabinet 100 has communication needs, it is generally equipped with a SIM card. Using a SIM card will incur communication fees, which is not cost-effective in places with WIFI. For the power bank cabinet 100 that is not equipped with a WIFI receiving module, the expansion module 200 including the WIFI receiving module can be inserted to connect to WIFI for communication.
[0039] In the second embodiment, the expansion module 200 includes a WIFI enhancement module. The expansion module 200 can be adapted to the power bank cabinet 100 provided with a WIFI receiving module to enhance the WIFI signal and thus improve the stability of the WIFI connection.
[0040] In the third embodiment, the expansion module 200 includes a power supply module, and the power supply module includes a USB power supply interface, and the USB power supply interface is exposed at the insertion port 112. The existing power bank cabinet 100 is usually used with an external 220V AC power supply. This also leads to the inability to set up a power bank cabinet 100 in places where AC power cannot be provided. Although some businesses use a storage power supply to output 220V AC power to the power bank cabinet 100 through an inverter, the cost is very high. The expansion module 200 of this embodiment is provided with a power supply module, and the power supply module includes a USB power supply interface exposed at the insertion port 112, so that the power bank cabinet 100 can be powered by a power bank in combination with a USB charging cable.
[0041] refer to Figure 5-10 In a specific embodiment, the power bank cabinet 100 also includes an elastic card block 130, which includes an elastic arm 131 and a hook 132 connected to the elastic arm 131. One end of the elastic arm 131 is connected to the shell 110, and the hook 132 is blocked at the insertion port 112 and is used to abut against the expansion module 200.
[0042] Specifically, it is only necessary to drive the elastic arm 131 to deform, and then drive the hook 132 to move, so that the hook 132 moves to a position that does not affect the insertion of the expansion module 200, and the expansion module 200 can be smoothly inserted into the insertion port 112. After the expansion module 200 is inserted, the elastic arm 131 can restore the deformation to block the hook 132 at the insertion port 112. At this time, the hook 132 will abut against the expansion module 200. Under the limiting action of the hook 132, it can be ensured that the expansion module 200 can be stably inserted into the shell 110, and the first electrical connection structure 121 can be in good contact with the second electrical connection structure 210.
[0043] In one embodiment, the hook 132 abuts against the outer edge of the expansion module 200 , thereby ensuring that the expansion module 200 is stably inserted into the housing 110 .
[0044] In another specific embodiment, a slot 230 is defined on the expansion module 200 , and the hook 132 is inserted into the slot 230 and abuts against the slot wall of the slot 230 , thereby ensuring that the expansion module 200 is stably inserted into the housing 110 .
[0045] refer to Figure 5 、 Figure 8 In some embodiments, the other end of the elastic arm 131 protrudes from the insertion port 112 .
[0046] Specifically, when removing the expansion module 200, it is necessary to first apply force to the elastic arm 131 to move the hook 132 to a position where it does not interfere with the removal of the expansion module 200. This allows for smooth removal of the expansion module 200. If the other end of the elastic arm 131 were flush with or hidden inside the insertion port 112, it would be difficult to apply force to the elastic arm 131. To address this technical issue, the present embodiment configures the elastic arm 131 so that its other end protrudes from the insertion port 112, making it easier for the user to apply force to the other end of the elastic arm 131.
[0047] refer to Figure 7 In some embodiments, the elastic block 130 and the housing 110 are integrally formed, which can reduce the cost of mold making and assembly, thereby reducing production costs. Even after long-term use, the connection between the elastic block 130 and the housing 110 will not become loose.
[0048] refer to Figure 11 In some embodiments, a first abutting step 140 is provided in the installation cavity. The first abutting step 140 is oriented toward the insertion port 112 ( Figure 11 The expansion module 200 is provided with a second abutting step 220 used in conjunction with the first abutting step 140 and is arranged opposite to the insertion port 112 in the X direction.
[0049] By implementing this embodiment, the user inserts the expansion module 200 into the insertion port 112 until the first abutting step 140 abuts the second abutting step 220. The expansion module 200 is fully inserted and is prevented from further insertion by the first abutting step 140. This embodiment has the beneficial effect of effectively preventing damage to the first electrical connection structure 121 and the second electrical connection structure 210 caused by excessive force applied by the user.
[0050] refer to Figure 6In some embodiments, the first electrical connection structure 121 is either a spring pin or a metal contact, and the second electrical connection structure 210 is the other of the spring pin and the metal contact. With this arrangement, the main control module 120 and the expansion module 200 can be electrically connected simply by connecting the first and second electrical connection structures 210. This is very convenient and eliminates the need to align a plug with a socket for electrical connection.
[0051] Of course, it is understandable that the first electrical connection structure 121 may also be a TYPE-C interface, a Micro-USB interface, etc.
[0052] refer to Figure 2 In some embodiments, the power bank cabinet 100 further includes a block 150 , which is installed on a side of the insertion port 112 facing away from the installation cavity to cover or expose the insertion port 112 .
[0053] By implementing this embodiment, the blocking block 150 can be used to shield the insertion port 112 , thereby preventing the interior of the power bank cabinet 100 from being affected by the external environment and improving the aesthetics of the power bank cabinet 100 .
[0054] It is worth mentioning that there are many specific implementations of the block 150, for example, the block 150 is mounted on the shell 110 by magnetic attraction, the block 150 is rotatably connected to the shell 110, the block 150 is slidably connected to the shell 110, etc., which are not limited in this embodiment.
[0055] In some embodiments, a receiving groove 113 is defined on the exterior of the housing 110 , and the insertion port 112 is formed on a wall of the receiving groove 113 . The receiving groove 113 is used to receive the stopper 150 .
[0056] By implementing this embodiment, the stopper 150 will not protrude from the housing 110 after being installed in the housing 110 , which can further improve the aesthetics of the stopper 150 when installed in the housing 110 .
[0057] refer to Figure 2 、 Figure 5 In some embodiments, a receiving groove 113 is provided on the outside of the housing 110 , and the insertion port 112 is opened at the bottom of the receiving groove 113 , and the receiving groove 113 is used to receive the stopper 150 .
[0058] By implementing this embodiment, the stopper 150 does not protrude from the housing 110 after being installed in the housing 110, which can further improve the aesthetics of the stopper 150 when installed in the housing 110. In addition, the insertion opening 112 is opened at the bottom of the receiving groove 113, which means that the insertion opening 112 and the notch of the receiving groove 113 are opposite each other. Compared with the embodiment in which the insertion opening 112 and the notch of the receiving groove 113 are not opposite each other, this embodiment does not require the expansion module 200 to be placed in its entirety into the receiving groove 113 before inserting the expansion module 200 into the insertion opening 112. Not only is insertion more convenient, but the size of the receiving groove 113 can also be set to be relatively small, which is conducive to the miniaturization of the power bank cabinet 100.
[0059] In some embodiments, the stopper 150 is made of elastic material, and the stopper 150 has an interference fit with the groove wall of the accommodating groove 113. The accommodating groove 113 is arranged on the first surface 114 of the shell 110. The groove wall of the accommodating groove 113 is provided with a hand latch groove 115, and the hand latch groove 115 is connected to the first surface 114.
[0060] Because the stopper 150 is elastic and has an interference fit with the wall of the receiving groove 113, the stopper 150 is very stable when installed in the receiving groove 113 and will not easily fall out of the receiving groove 113. However, this also makes it difficult for the user to apply force to the stopper 150 to drive the stopper 150 out of the receiving groove 113. Therefore, this embodiment further provides a finger-grip groove 115 on the wall of the receiving groove 113. Since the receiving groove 113 is provided on the first surface 114 of the housing 110 and the finger-grip groove is connected to the first surface 114, the finger-grip groove 115 can expose the side wall of the stopper 150, so that the user can use the finger-grip groove to apply force to the stopper 150, thereby driving the stopper 150 out of the receiving groove 113.
[0061] In some embodiments, the power bank cabinet 1000 further includes a stopper movably mounted on the side of the elastic arm 131 facing away from the hook 132. By simply inserting the stopper to the side of the elastic arm 131 facing away from the hook 132, the elastic arm 131 can be effectively prevented from deforming due to external forces and causing the hook 132 to disengage from the expansion module 200.
[0062] In a specific embodiment, the stopper and the stopper 150 are integrally formed, which reduces the manufacturing cost and the assembly cost while also reducing the number of steps for the user to operate the stopper and the stopper 150 , resulting in an excellent user experience.
[0063] The present invention also provides a charging device 1000. Figure 1As shown, the charging device 1000 includes a power bank cabinet 100 and an expansion module 200. The power bank cabinet 100 is the power bank cabinet 100 shown in the above embodiment. The expansion module 200 is provided with a second electrical connection structure 210. The expansion module 200 is inserted into the insertion port 112 of the power bank cabinet 100. The second electrical connection structure 210 is connected to the first electrical connection structure 121 of the power bank cabinet 100, thereby electrically connecting the main control module 120 and the expansion module 200. The expansion module 200 can be used to expand the functions of the power bank cabinet 100.
[0064] In a specific embodiment, the expansion module 200 includes a WIFI receiving module. Since the power bank cabinet 100 has communication needs, it is generally equipped with a SIM card. Using a SIM card will incur communication fees, which is not cost-effective in places with WIFI. For the power bank cabinet 100 that is not equipped with a WIFI receiving module, the expansion module 200 including the WIFI receiving module can be inserted to connect to WIFI for communication.
[0065] In another specific embodiment, the expansion module 200 includes a WIFI enhancement module. The expansion module 200 can be adapted to the power bank cabinet 100 provided with a WIFI receiving module to enhance the WIFI signal and thus improve the stability of the WIFI connection.
[0066] In another specific embodiment, the expansion module 200 includes a power supply module, and the power supply module includes a USB power supply interface, and the USB power supply interface is exposed at the insertion port 112. The existing power bank cabinet 100 is usually used with an external 220V AC power supply. This also leads to the inability to set up a power bank cabinet 100 in places where AC power cannot be provided. Although some businesses use a storage power supply to output 220V AC power to the power bank cabinet 100 through an inverter, the cost is very high. The expansion module 200 of this embodiment is provided with a power supply module, and the power supply module includes a USB power supply interface exposed at the insertion port 112, so that the power bank cabinet 100 can be powered by a power bank in combination with a USB charging cable.
[0067] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
