Description

Technical Field

[0001] This application relates to the field of electronic device technology, and in particular to a retractable and dual-purpose charging dock. Background Technology

[0002] With the rapid development of payment technology, financial terminals such as POS machines or PDA machines have become indispensable devices in payment transactions. These devices are not only used to process payment transactions, but also integrate multiple functions, such as printing receipts, scanning QR codes, and wireless communication. The realization of these functions depends on the battery inside the POS machine or PDA machine. Therefore, in order to ensure the power supply of the POS machine or PDA machine in various usage scenarios, a charging dock is required as a supporting device.

[0003] Currently, traditional POS machine or PDA charging docks use a fixed structure design, meaning the charging interface or pin positions are fixed. Most charging docks on the market can only charge the bare device. However, with increasing market demand, many POS machines or PDAs have protective covers to protect them from damage or scratches. However, when a protective cover is installed, the original charging dock cannot accommodate the size change, requiring the cover to be removed before charging. This causes inconvenience and cannot simultaneously meet the charging needs of POS machines with and without protective covers. Summary of the Invention

[0004] To address the aforementioned technical problems, this application provides a retractable and dual-purpose charging dock, the device comprising:

[0005] Panel cover, spring components, front shell, charging spring pins, mounting bracket, PCBA board and bottom shell;

[0006] The front shell and the bottom shell are connected to form a placement area;

[0007] Both the fixed bracket and the PCBA board are disposed in the placement area;

[0008] The faceplate has an opening, and the panel cover is disposed in the faceplate through the opening. The charging spring pin is installed in the panel cover and connected to the PCBA board. One end of the spring is connected to the panel cover, and the other end of the spring is connected to the bottom shell through the fixing bracket. The panel cover cooperates with the spring to move telescopically in the opening of the faceplate and to charge the POS machine or PDA machine through the charging spring.

[0009] Optionally, a first limiting groove and a second limiting groove are respectively provided on both sides of the inner wall of the opening, and a first limiting block and a second limiting block are provided on the panel cover corresponding to the first limiting groove and the second limiting groove. The panel cover is engaged in the first limiting groove and the second limiting groove by the first limiting block and the second limiting block.

[0010] Optionally, the panel cover is provided with a first slot, the size of which is larger than the size of the charging spring pin.

[0011] Optionally, the panel cover is provided with a second slot, which is located on one side of the first slot, and the second slot is used to snap on the protective cover of the POS machine or PDA machine.

[0012] Optionally, the fixed bracket is provided with an integrally formed first positioning sleeve and a second positioning sleeve, the first positioning sleeve and the second positioning sleeve extending toward the panel cover, and a preset distance is provided between the first positioning sleeve and the second positioning sleeve.

[0013] Optionally, the spring component includes a first spring and a second spring, wherein the first spring is disposed in the first positioning sleeve and the second spring is disposed in the second positioning sleeve.

[0014] Optionally, the panel cover is provided with a first movement groove and a second movement groove. The first movement groove is used for one end of the first spring, and the second movement groove is used to accommodate one end of the second spring. The other ends of the first spring and the second spring are both connected to the bottom shell.

[0015] Optionally, the dimensions of the panel cover are adapted to the opening dimensions on the faceplate.

[0016] Optionally, a socket opening is provided on one side of the faceplate, and the PCBA board is connected to the socket opening.

[0017] Optionally, the bottom of the base shell is provided with silicone feet.

[0018] As can be seen from the above technical solutions, this application has the following advantages:

[0019] The charging stand of this application, through the telescopic arrangement of spring components and a panel cover, allows it to adapt to the charging needs of POS machines or PDAs with and without protective covers. When charging a POS machine or PDA with a protective cover, the spring on the fixed bracket pushes the panel cover to a predetermined position on the cover, and the charging spring pins facilitate charging. When charging a POS machine or PDA without a protective cover, the weight of the POS machine or PDA presses the panel cover down to a predetermined position on the fixed plate, and the charging spring pins facilitate charging, thus ensuring a stable charging experience. This eliminates the need to remove the protective cover or replace the charging stand when charging a POS machine or PDA, greatly improving the charging stand's applicability and meeting the charging needs of POS machines and PDAs.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Please see Figures 1 to 2 This application provides a retractable dual-purpose charging dock, including: a panel cover 1, a spring member, a front shell 12, a charging spring pin 13, a fixing bracket 14, a PCBA board 17, and a bottom shell 18.

[0029] The front shell 12 and the bottom shell 18 are connected to form a placement area;

[0030] The mounting bracket 14 and the PCBA board 17 are both located in the placement area;

[0031] The front cover 12 has an opening 9. The panel cover 1 is installed in the front cover 12 through the opening 9. The charging spring pin 13 is installed in the panel cover 1 and connected to the PCBA board 17. One end of the spring is connected to the panel cover 1, and the other end of the spring is connected to the bottom cover 18 through the fixing bracket 14. The panel cover 1 works with the spring to move telescopically in the opening 9 of the front cover 12 and to charge the POS machine or PDA machine through the charging spring pin 13.

[0032] First, let me introduce the function and purpose of each component in this application:

[0033] Panel cover 1: As a component that directly contacts the charging base with the POS machine or PDA machine, a charging spring pin 13 is installed on the panel cover 1. Under the action of the spring, the panel cover 1 can move up and down in the opening 9 of the face shell 12 to accommodate the charging needs of POS machines or PDA machines with and without protective covers.

[0034] Spring component: Connects the panel cover 1 and the fixed bracket 14, providing telescopic force so that the panel cover 1 can automatically adjust its position according to the weight of the POS machine or PDA. When the POS machine or PDA without a protective cover is placed on the charging base, the spring component will be compressed due to the weight of the POS machine or PDA, thereby driving the panel cover 1 to move downward and press down to the position of the fixed bracket 14. Then, it will be charged through the charging spring pin 13. When the POS machine or PDA with a protective cover is placed on the charging base, the protective cover on the POS machine or PDA will be locked onto the panel cover 1. At this time, the panel cover 1 will not move downward. The panel cover 1 will be locked at the height defined by the faceplate 12 and will be charged through the charging spring pin 13.

[0035] Faceplate 12: Connected to bottom shell 18 to form a closed placement area, protecting internal components from interference from the external environment. Opening 9 is provided on faceplate 12 to allow panel cover 1 to extend and retract.

[0036] Charging spring pin 13: As an electrical connection component between the charging base and the POS machine or PDA machine, it is responsible for transmitting charging current. The charging spring pin 13 is mounted on the panel cover 1 and connected to the PCBA board 17. The charging spring pin 13 has good elasticity and conductivity.

[0037] Fixed bracket 14: Fixed bracket 14 is installed in the bottom shell 18. Fixed bracket 14 is connected to the other end of the spring. PCBA board 17 is installed on fixed bracket 14.

[0038] PCBA board 17: This is the circuit board used as the charging dock, responsible for power transmission, charging control, and signal processing.

[0039] Bottom shell 18: Connected to the front shell 12 to form a placement area, protecting the internal components from impact and vibration. The bottom shell 18 provides bottom support for the charging base, ensuring that the charging base can be placed stably.

[0040] In practical applications, when the charging dock is not in use, the panel cover 1 is held in the set position in the opening 9 of the faceplate 12 by the action of the spring. When charging a POS machine or PDA with a protective case, the POS machine or PDA with a protective case is placed on the panel cover 1, and the panel cover 1 can fix the POS machine or PDA with a protective case well. At this time, the panel cover 1 will not move down. After the POS machine or PDA with a protective case is fixed, the charging spring pin 13 contacts the charging interface of the POS machine or PDA, thereby starting to charge the POS machine or PDA with a protective case.

[0041] When charging a POS machine or PDA without a protective case, the weight of the POS machine or PDA presses down on the panel cover 1, causing the panel cover 1 to move downwards until it reaches the limited position of the fixed bracket 14. The charging spring pin 13 then contacts the charging interface of the POS machine or PDA, and the charging process for the POS machine or PDA without a protective case begins.

[0042] In an optional embodiment, a first limiting groove 10 and a second limiting groove 11 are respectively provided on both sides of the inner wall of the opening 9. A first limiting block 3 and a second limiting block 4 are provided on the panel cover 1 corresponding to the first limiting groove 10 and the second limiting groove 11. The panel cover 1 is engaged in the first limiting groove 10 and the second limiting groove 11 by the first limiting block 3 and the second limiting block 4.

[0043] In this embodiment of the application, a first limiting groove 10 and a second limiting groove 11 are respectively provided on both sides of the inside of the opening 9 of the face shell 12. The first limiting groove 10 and the second limiting groove 11, together with the first limiting block 3 and the second limiting block 4, are used to limit the panel cover 1 in the vertical direction to prevent the panel cover 1 from deviating from the predetermined trajectory or moving excessively during the extension and retraction process.

[0044] The panel cover 1 is provided with a first limiting block 3 and a second limiting block 4 on both sides. The first limiting block 3 and the second limiting block 4 correspond to the first limiting groove 10 and the second limiting groove 11, and together serve as limiting components of the panel cover 1, thereby limiting the movement range of the panel cover 1.

[0045] In practical applications, when assembling the charging base, the panel cover 1 is pushed into the opening 9, and the first limiting block 3 and the second limiting block 4 of the panel cover 1 are aligned with the first limiting groove 10 and the second limiting groove 11, respectively. Then, the first limiting block 3 and the second limiting block 4 are engaged in the first limiting groove 10 and the second limiting groove 11, so that the panel cover 1 is fixed in the opening 9 of the face shell 12 through the cooperation of the first limiting block 3, the second limiting block 4, the first limiting groove 10 and the second limiting groove 11, while retaining the ability to telescopically move.

[0046] When a POS machine or PDA without a protective cover is placed on the charging dock, the panel cover 1 moves telescopically under the action of the spring. During the movement, the first limiting block 3 and the second limiting block 4 always slide in the first limiting groove 10 and the second limiting groove 11, ensuring that the panel cover 1 moves along the predetermined trajectory. The cooperation of the limiting groove and the limiting block effectively prevents the panel cover 1 from shifting or shaking during the movement, thus improving the stability and reliability of the charging dock.

[0047] In an optional embodiment, the panel cover 1 is provided with a first slot 20, the size of which is larger than the size of the charging spring pin 13.

[0048] In this embodiment of the application, the first slot 20 is provided on the panel cover 1. The shape of the first slot 20 is adapted to the shape of the charging spring pin 13, but the size of the first slot 20 is larger than the size of the charging spring pin 13, so as to ensure that the charging spring pin 13 can be well placed in the first slot 20 and connected to the charging interface on the POS machine or PDA machine.

[0049] In an optional embodiment, the panel cover 1 is provided with a second slot 2, which is located on one side of the first slot 20. The second slot 2 is used to attach a protective cover to a POS machine or PDA machine.

[0050] In this embodiment of the application, the second slot 2 is provided on the panel cover 1 and is located on one side of the first slot 20. The shape and size of the second slot 2 on the panel cover 1 match the corresponding part of the POS machine or PDA machine protective cover. The shape of the second slot 2 can be rectangular, arc or other suitable shape. This application does not make specific limitations and can be set according to the actual situation.

[0051] It should be noted that the depth and width of the second slot 2 ensure that the protective cover of the POS machine or PDA machine can be securely fastened therein without being too tight or too loose, and ensure that the POS machine or PDA machine with the protective cover will not move downwards when placed on the panel cover 1.

[0052] In practical applications, when a POS machine or PDA with a protective cover is placed on the panel kit, the corresponding part of the protective cover will fall into the second slot 2. Since the shape and size of the second slot 2 match the corresponding part of the protective cover, the protective cover can be firmly locked in it without sliding or shifting, and the POS machine or PDA can be charged through the charging spring pin 13.

[0053] In an optional embodiment, the fixed bracket 14 is provided with an integrally formed first positioning sleeve 15 and second positioning sleeve 16, the first positioning sleeve 15 and the second positioning sleeve 16 extending toward the panel cover 1, and a preset distance is provided between the first positioning sleeve 15 and the second positioning sleeve 16.

[0054] In this embodiment, the first positioning sleeve 15 and the second positioning sleeve 16 are both disposed on the fixed bracket 14 and extend toward the panel cover 1. The shape of the first positioning sleeve 15 and the second positioning sleeve 16 is preferably cylindrical, but can also be square or other suitable shapes. No specific limitation is made here, and can be set according to the actual situation.

[0055] The first positioning sleeve 15 and the second positioning sleeve 16 are integrally formed with the fixed bracket 14, that is, the connection between the first positioning sleeve 15 and the second positioning sleeve 16 and the fixed bracket 14 is non-removable. The integral forming method can effectively enhance the integrity and stability of the structure.

[0056] A preset distance is provided between the first positioning sleeve 15 and the second positioning sleeve 16. This preset distance ensures that the spring has sufficient compression and rebound space during the telescopic movement of the panel cover 1, while also maintaining the compactness of the charging base structure. In practical applications, when the panel cover 1 telescopically moves under the action of the spring, the spring moves along the first positioning sleeve 15 and the second positioning sleeve 16, ensuring the accuracy and stability of the movement of the panel cover 1.

[0057] In an optional embodiment, the spring element includes a first spring 7 and a second spring 8, the first spring 7 being disposed in a first positioning sleeve 15 and the second spring 8 being disposed in a second positioning sleeve 16.

[0058] In this embodiment, the first spring 7 and the second spring 8 can be compression springs, tension springs, or other suitable types of springs, which can be selected according to the specific needs of the charging dock. No specific limitations are made here.

[0059] The first spring 7 and the second spring 8 work together to provide a telescopic force to the panel cover 1, enabling the panel cover 1 to telescopically move under the action of the first spring 7 and the second spring 8.

[0060] In an optional embodiment, the panel cover 1 is provided with a first motion groove 5 and a second motion groove 6. The first motion groove 5 is used for one end of the first spring 7, and the second motion groove 6 is used to accommodate one end of the second spring 8. The other ends of the first spring 7 and the second spring 8 are both connected to the bottom shell 18.

[0061] In this embodiment of the application, the first motion groove 5 and the second motion groove 6 are disposed on the back of the panel cover 1. The first motion groove 5 and the second motion groove 6 are disposed to facilitate the connection of springs and provide connection points for the first spring 7 and the second spring 8 on the panel cover 1. The shapes of the first motion groove 5 and the second motion groove 6 are set according to the shapes of the first spring 7 and the second spring 8, and are not specifically limited here.

[0062] In practical applications, when assembling the charging base, one end of the first spring 7 is aligned with the first movement groove 5 of the panel cover 1, and then the other end of the first spring 7 is connected to the bottom shell 18 via the first positioning sleeve 15. Similarly, one end of the second spring 8 is aligned with the second movement groove 6 of the panel cover 1, and then the other end of the second spring 8 is also fixed in the bottom shell 18. Thus, the first spring 7 and the second spring 8 are connected through the first movement groove 5, the second movement groove 6, the first positioning sleeve 15, the second positioning sleeve 16, and the bottom shell 18, and are firmly fixed in the charging base, providing elastic support for the telescopic movement of the panel cover 1.

[0063] In an alternative embodiment, the dimensions of the panel cover 1 are adapted to the dimensions of the opening 9 on the faceplate 12.

[0064] In this embodiment, the size of the panel cover 1 matches the size of the opening 9 on the face shell 12, ensuring that the panel cover 1 can cover the opening 9, thereby helping to improve the overall aesthetic appearance of the charging dock, and effectively preventing external impurities such as dust and moisture from entering the charging dock. Furthermore, the panel cover 1 can smoothly extend and retract within the opening 9 without interfering with the face shell 12.

[0065] It should be noted that the dimensions of the openings 9 on the panel cover 1 and the shell 12 are not specifically limited here, and can be set according to the actual situation.

[0066] In an optional embodiment, a socket opening 21 is provided on one side of the faceplate 12, and the PCBA board 17 is connected to the socket opening 21.

[0067] In this embodiment, the socket opening 21 is provided on the side of the faceplate 12 to facilitate the insertion of external devices. The socket opening 21 ensures that the external charging plug can be smoothly inserted and connected to the interface on the PCBA board 17, thereby ensuring that external power can enter the charging base and charge the POS machine or PDA machine through the charging spring pin 13 on the charging base.

[0068] In an optional embodiment, the bottom of the base 18 is provided with silicone feet 19.

[0069] In this embodiment, silicone feet 19 are installed at the four corners of the base shell 18. Silicone has good elasticity, wear resistance, anti-slip properties, and corrosion resistance, effectively protecting the base shell 18 and the placement surface while providing stable support. Furthermore, the silicone feet 19 have good anti-slip properties, increasing the friction between the charging base and the placement surface, preventing the charging base from sliding or shifting during placement. They also have a certain degree of elasticity, which can absorb shock; when the charging base is subjected to external impact or vibration, the feet can absorb some energy, reducing damage to the base shell 18 and the placement surface.

[0070] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
