[0002] In existing point-of-sale (POS) terminal charging dock designs, spring-loaded connectors are widely used due to their ease of insertion and removal, enabling charging on demand. Traditional spring-loaded connectors typically consist of a spring pin, a syringe barrel, and a spring. Current conduction is achieved through a sliding contact between the spring pin and the syringe barrel.
[0003] However, with long-term use, the repeated friction between the spring pin and the syringe in existing spring pin connectors can increase the contact resistance between them. When charging with high current, the spring pin connector will overheat severely, resulting in a poor user experience. Utility Model Content

The charging connection assembly includes: a first syringe and a charging spring pin. The first syringe is mounted on the charging circuit board assembly, and the charging spring pin is movably disposed in the first syringe, with its two ends protruding from opposite ends of the first syringe. One end of the charging spring pin is used to make conductive contact with the device to be charged, and the other end of the charging spring pin is electrically connected to the charging circuit board assembly, so that the charging circuit board assembly can be electrically connected to the device to be charged solely through the charging spring pin.
[0006] Optionally, the charging connection assembly further includes a first elastic element located between the first syringe and the charging spring needle, for applying a first elastic force to the charging spring needle. When the device to be charged corresponds to the position of the charging connection assembly, the first elastic force is directed towards the device to be charged, and the charging spring needle can maintain conductive contact with the device to be charged through the elastic force.
[0007] According to another aspect of this application, a charging module is provided, which includes a charging circuit board assembly and a charging connection assembly. The charging connection assembly is the aforementioned charging connection assembly. The charging circuit board assembly includes a charging circuit board body and a flexible electrical connection portion, which electrically connects the other end of the charging spring pin and the charging circuit board body.
[0008] Optionally, the charging module further includes a signal connection component, which includes a second syringe and a signal spring. The second syringe is mounted on and electrically connected to the charging circuit board assembly. The signal spring is movably inserted through the second syringe and electrically connected to it. One end of the signal spring extends from the end of the second syringe for conductive contact with the device to be charged, so that the charging circuit board assembly can be electrically connected to the device to be charged in sequence through the second syringe and the signal spring.
[0009] Optionally, the signal connection assembly further includes a second elastic element located between the second syringe and the signal spring needle, for applying a second elastic force to the signal spring needle. When the device to be charged corresponds to the position of the charging connection assembly, the second elastic force is directed towards the device to be charged, and the signal spring needle can maintain conductive contact with the device to be charged through the elastic force.
[0010] Optionally, the flexible electrical connection includes a flexible circuit board. The main body of the charging circuit board is provided with a first connection interface, and the flexible circuit board is provided with a second connection interface. The flexible circuit board is electrically connected to the main body of the charging circuit board through the cooperation of the first connection interface and the second connection interface. The flexible circuit board is provided with a first solder pad structure, and the other end of the charging spring pin is soldered and fixed to the first solder pad structure so that the charging spring pin is electrically connected to the flexible circuit board.
[0011] Optionally, the flexible electrical connection includes a flexible conductive wire, and a second pad structure is provided on the charging circuit board body. The first end of the flexible conductive wire is welded and fixed to the second pad structure, and the second end of the flexible conductive wire is welded and fixed to the other end of the charging spring pin, so that the flexible conductive wire is electrically connected to the charging circuit board body, and the charging spring pin is electrically connected to the charging circuit board body.
[0012] Optionally, the charging module includes a plurality of charging connection components, which are spaced apart on the charging circuit board assembly, and at least two of the plurality of charging connection components are capable of making conductive contact with the positive and negative electrodes of the device to be charged, respectively.
[0013] Optionally, the charging module includes multiple signal connection components, which are spaced apart on the charging circuit board assembly.
[0014] According to another aspect of this application, an electronic device is provided, which includes a charging device and a functional base device, wherein the functional base device includes a charging module, and the charging module is the charging module described above.
[0015] The beneficial effects of the charging module provided in this application are as follows: Compared with the prior art, the charging connection component provided in this application movably sets the charging spring pin in the first syringe, and sets the two ends of the charging spring pin to extend from the opposite ends of the first syringe, so that the charging connection component can make conductive contact with the device to be charged through one end of the charging spring pin, and electrically connect to the charging circuit board assembly through the other end of the charging spring pin. In this way, the charging circuit board assembly can achieve electrical connection with the device to be charged only through the charging spring pin. That is, the current can be directly transmitted between the charging circuit board assembly and the device to be charged through the charging spring pin, without passing through the first syringe. Since the current does not pass through the first syringe during transmission, the contact impedance between the charging spring pin and the first syringe increases, which will not affect the current transmission of the charging connection component. This avoids the serious overheating caused by the increased contact impedance between the charging spring pin and the first syringe during high-current charging, thus improving the user experience.

[0031] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0032] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly or indirectly on that other element. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to that other element. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0033] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0035] As described in the background section, spring-loaded connectors are widely used in existing point-of-sale (POS) charging dock designs due to their ease of insertion and removal, enabling convenient charging. Traditional spring-loaded connectors typically consist of a spring, a syringe, and a spring, with current flow achieved through a sliding contact between the spring and the syringe. However, with prolonged use, the repeated friction between the spring and the syringe increases the contact resistance, leading to significant overheating during high-current charging and a poor user experience.
[0036] It should be noted that the repeated friction between the spring pin and the syringe in the existing technology will lead to an increase in the contact resistance between them. This refers to the fact that in the traditional spring pin connector structure, due to the sliding contact mechanism between the spring pin and the inner wall of the syringe, mechanical wear will occur during long-term use. At this time, the continuous friction between the outer surface of the spring pin and the inner wall of the syringe will cause the metal plating to peel off and the substrate to oxidize. Furthermore, with the long-term use of the spring pin and the syringe, impurities in the external environment may enter the sliding contact area between the spring pin and the syringe, which will further increase the contact resistance between the spring pin and the syringe.
[0037] It is understood that the high-current charging in this embodiment refers to a charging situation where the charging current is greater than or equal to 2A.
[0038] See Figure 1 and Figure 2As shown, in order to solve the above problems, according to one aspect of this application, an embodiment of this application provides a charging connection assembly for electrically connecting a charging circuit board assembly 10 and a device to be charged. The charging connection assembly includes a first syringe 21 and a charging spring pin 22. The first syringe 21 is mounted on the charging circuit board assembly 10, and the charging spring pin 22 is movably disposed in the first syringe 21, with both ends of the charging spring pin 22 protruding from opposite ends of the first syringe 21. One end of the charging spring pin 22 is used for conductive contact with the device to be charged, and the other end of the charging spring pin 22 is electrically connected to the charging circuit board assembly 10, so that the charging circuit board assembly 10 can be electrically connected to the device to be charged only through the charging spring pin 22. The charging connection assembly provided in this embodiment movably mounts the charging spring pin 22 onto the first syringe 21, with both ends of the charging spring pin 22 extending from opposite ends of the first syringe 21. This allows the charging connection assembly to make conductive contact with the device to be charged through one end of the charging spring pin 22, and to electrically connect to the charging circuit board assembly 10 through the other end of the charging spring pin 22. This enables the charging circuit board assembly 10 to achieve electrical connection with the device to be charged solely through the charging spring pin 22. In other words, current can be directly transmitted between the charging circuit board assembly and the device to be charged via the charging spring pin 22, without passing through the first syringe 21. Since the current does not pass through the first syringe 21 during transmission, the contact resistance between the charging spring pin 22 and the first syringe 21 increases, which does not affect the current transmission of the charging connection assembly. This avoids severe overheating caused by increased contact resistance between the charging spring pin 22 and the first syringe 21 during high-current charging, thus improving the user experience.
[0039] In some embodiments, the charging spring pin 22 in this embodiment is made of a conductive material, such as copper, copper alloy, gold-plated metal, conductive composite material, etc.
[0040] In some embodiments, the first syringe 21 in this embodiment is made of a conductive material, such as copper, copper alloy, gold-plated metal, conductive composite material, etc.
[0041] In other embodiments, the first syringe 21 in this embodiment is made of an insulating material, such as engineering plastics, ceramics, glass fiber reinforced polymers, etc.
[0042] See Figure 1 and Figure 2As shown, in some embodiments, the first syringe 21 in this embodiment is provided with a through hole connecting both ends of the first syringe 21, and the charging spring needle 22 in this embodiment is movably inserted through the through hole. By providing a through hole on the first syringe 21, the first syringe 21 can guide the movement of the charging spring needle 22 through the cooperation of the through hole and the charging spring needle 22, ensuring that the charging spring needle 22 can stably make conductive contact with the device to be charged.
[0043] In some embodiments, a first limiting structure is provided on the inner wall of the through hole, and a second limiting structure is provided on the outer wall of the charging spring needle 22. The first syringe 21 restricts the axial movement of the charging spring needle 22 through the cooperation of the first limiting structure and the second limiting structure. By providing a first limiting structure on the inner wall of the through hole and a second limiting structure on the outer wall of the charging spring needle 22, the first syringe 21 can restrict the axial movement of the charging spring needle 22 through the cooperation of the first limiting structure and the second limiting structure, ensuring that the charging spring needle 22 can reliably make conductive contact with the device to be charged.
[0044] In some embodiments, the first limiting structure in this embodiment includes a first limiting groove extending along the through-hole length direction, and the second limiting structure includes a first limiting protrusion. The first limiting protrusion is adapted to the first limiting groove. The first syringe 21 restricts the axial movement of the charging spring needle 22 through the cooperation of the first limiting groove and the first limiting protrusion. By providing a first limiting groove on the inner sidewall of the through hole and a first limiting protrusion on the outer sidewall of the charging spring needle 22, the first syringe 21 can restrict the axial movement of the charging spring needle 22 through the cooperation of the first limiting groove and the first limiting protrusion, ensuring that the charging spring needle 22 can reliably make conductive contact with the device to be charged.
[0045] See Figure 2 As shown, in one specific embodiment, the charging connection assembly further includes a first elastic element 23. The first elastic element 23 is located between the first syringe 21 and the charging spring needle 22, and is used to apply a first elastic force to the charging spring needle 22. When the device to be charged corresponds to the position of the charging connection assembly, the first elastic force is directed towards the device to be charged, and the charging spring needle 22 can maintain conductive contact with the device to be charged through the first elastic force. By providing the first elastic element 23 between the first syringe 21 and the charging spring needle 22, the charging spring needle 22 can maintain conductive contact with the device to be charged through the first elastic force applied to it by the first elastic element 23 towards the device to be charged when the position of the device to be charged corresponds to the position of the charging connection assembly.
[0046] In some embodiments, the first elastic element 23 in this embodiment includes a first compression spring. In this embodiment, the first compression spring is sleeved on the charging spring needle 22 and located within the through hole. Both ends of the first compression spring abut against the first syringe 21 and the charging spring needle 22, respectively, to apply axial elastic force to the charging spring needle 22. By sleeved on the charging spring needle 22 and simultaneously abutting against the first syringe 21 and the charging spring needle 22, the charging connection assembly can provide stable contact pressure to the charging spring needle 22 through the first compression spring, ensuring that the charging connection assembly maintains reliable conductive contact performance after prolonged use.
[0047] In some embodiments, the first compression spring in this embodiment is a pre-compression spring. Setting the first compression spring as a pre-compression spring allows it to maintain its initial elastic preload after assembly, ensuring that the charging spring pin 22 has stable contact pressure from its initial position, thereby improving the contact reliability of the charging connection assembly and extending its service life.
[0048] See Figures 3 to 6 As shown, according to another aspect of this application, a charging module is provided. The charging module includes a charging circuit board assembly 10 and a charging connection assembly 20. The charging connection assembly 20 is the aforementioned charging connection assembly 20. The charging circuit board assembly 10 includes a charging circuit board body 11 and a flexible electrical connection portion 12. The flexible electrical connection portion 12 electrically connects the other end of the charging spring pin 22 to the charging circuit board body 11. It should be noted that by connecting the other end of the charging spring pin 22 to the charging circuit board body 11 through the flexible electrical connection portion 12, a stable electrical connection can be established between the other end of the charging spring pin 22 and the charging circuit board body 11, without affecting the axial movement freedom of the charging spring pin 22. That is, the flexible electrical connection portion 12 can adapt to the axial movement stroke of the charging spring pin 22 through its bendability, ensuring that the charging spring pin 22 can be adapted to different specifications of the device to be charged.
[0049] See Figures 3 to 6As shown, in a specific embodiment, the charging module further includes a signal connection component 30. The signal connection component 30 includes a second syringe 31 and a signal spring 32. The second syringe 31 is mounted on the charging circuit board assembly 10 and electrically connected to the charging circuit board assembly 10. The signal spring 32 is movably inserted through the second syringe 31 and electrically connected to the second syringe 31. One end of the signal spring 32 extends out from the end of the second syringe 31 and is used to make conductive contact with the device to be charged, so that the charging circuit board assembly 10 can be electrically connected to the device to be charged in sequence through the second syringe 31 and the signal spring 32. By movably setting the signal ejector pin 32 on the second syringe 31, and setting one end of the signal ejector pin 32 to extend out from the end of the second syringe 31, the signal connection assembly 30 can make conductive contact with the device to be charged through one end of the signal ejector pin 32. By setting the signal ejector pin 32 to be electrically connected to the second syringe 31, and setting the second syringe 31 to be electrically connected to the charging circuit board assembly 10, the charging circuit board assembly 10 can sequentially achieve electrical connection with the device to be charged through the second syringe 31 and the signal ejector pin 32, thereby realizing signal transmission between the charging circuit board assembly 10 and the device to be charged.
[0050] In some embodiments, the signal fin 32 in this embodiment is made of a conductive material, such as copper, copper alloy, gold-plated metal, conductive composite material, etc.
[0051] In some embodiments, the second syringe 31 in this embodiment is made of a conductive material, such as copper, copper alloy, gold-plated metal, conductive composite material, etc.
[0052] See Figure 5 and Figure 6 As shown, in some embodiments, the second syringe 31 in this embodiment is provided with a mounting hole communicating with the end of the second syringe 31, and the signal ejector pin 32 in this embodiment is movably inserted through the mounting hole. By providing a mounting hole on the second syringe 31, the second syringe 31 can guide the movement of the signal ejector pin 32 through the cooperation of the mounting hole and the signal ejector pin 32, ensuring that the signal ejector pin 32 can stably make conductive contact with the device to be charged.
[0053] In some embodiments, a third limiting structure is provided on the inner wall of the mounting hole, and a fourth limiting structure is provided on the outer wall of the signal ejector pin 32. The second syringe 31 restricts the axial movement of the signal ejector pin 32 through the cooperation of the third and fourth limiting structures. By providing a third limiting structure on the inner wall of the mounting hole and a fourth limiting structure on the outer wall of the signal ejector pin 32, the second syringe 31 can restrict the axial movement of the signal ejector pin 32 through the cooperation of the third and fourth limiting structures, ensuring that the signal ejector pin 32 can reliably make conductive contact with the device to be charged.
[0054] In some embodiments, the third limiting structure in this embodiment includes a second limiting groove extending along the through-length direction, and the fourth limiting structure includes a second limiting protrusion. The second limiting protrusion is adapted to the first limiting groove. The second syringe 31 restricts the axial movement of the signal ejector pin 32 through the cooperation of the second limiting groove and the second limiting protrusion. By providing a second limiting groove on the inner sidewall of the mounting hole and a second limiting protrusion on the outer sidewall of the signal ejector pin 32, the second syringe 31 can restrict the axial movement of the signal ejector pin 32 through the cooperation of the second limiting groove and the second limiting protrusion, ensuring that the signal ejector pin 32 can reliably make conductive contact with the device to be charged.
[0055] See Figure 6 As shown, in one specific embodiment, the signal connection component 30 further includes a second elastic member 33. The second elastic member 33 is located between the second syringe 31 and the signal spring 32, and is used to apply a second elastic force to the signal spring 32. When the device to be charged corresponds to the position of the signal connection component 30, the second elastic force is directed towards the device to be charged, and the signal spring 32 can maintain conductive contact with the device to be charged through the elastic force. By providing the second elastic member 33 between the second syringe 31 and the signal spring 32, the signal spring 32 can maintain conductive contact with the device to be charged through the second elastic force applied to it by the second elastic member 33 towards the device to be charged when the position of the device to be charged corresponds to the position of the signal connection component 30.
[0056] In some embodiments, the second elastic element 33 in this embodiment includes a second compression spring. In this embodiment, the second compression spring is sleeved on the signal spring 32 and located within the mounting hole. Both ends of the second compression spring abut against the second syringe 31 and the signal spring 32, respectively, to apply axial elastic force to the signal spring 32. By sleeved on the signal spring 32 and simultaneously abutting both ends of the second compression spring against the second syringe 31 and the signal spring 32, the signal connection assembly 30 can provide stable contact pressure to the signal spring 32 through the second compression spring, ensuring that the signal connection assembly 30 maintains reliable conductive contact performance after prolonged use.
[0057] In some embodiments, the second compression spring in this embodiment is a pre-compression spring. Setting the second compression spring as a pre-compression spring allows it to maintain its initial elastic preload after assembly, ensuring that the signal spring pin 32 has stable contact pressure from its initial position, thereby improving the contact reliability of the signal connection assembly 30 and extending its service life.

At the same time, the other end of the charging spring pin 22 can be electrically connected to the second end of the flexible conductive wire by soldering to the second end of the flexible conductive wire.
[0061] See Figure 3 and Figure 4As shown, in one specific embodiment, the charging module includes multiple charging connection components 20, which are spaced apart on the charging circuit board assembly 10. At least two of the charging connection components 20 are capable of making conductive contact with the positive and negative terminals of the device to be charged, respectively. By setting the number of charging connection components 20 to multiple, and configuring at least two of the charging connection components 20 to make conductive contact with the positive and negative terminals of the device to be charged, a charging circuit can be formed between the charging circuit board assembly 10 and the device to be charged through the two charging connection components 20 that are in conductive contact with the positive and negative terminals of the device to be charged. This allows the charging module to effectively charge the device to be charged.
[0062] See Figure 3 and Figure 4 As shown, in one specific embodiment, the charging module includes multiple signal connection components 30, which are spaced apart on the charging circuit board assembly 10. By using multiple signal connection components 30, the charging module and the device to be charged can transmit signals simultaneously through multiple signal connection components 30, effectively improving the signal transmission efficiency between the charging module and the device to be charged.

The two charging connection components 20 are spaced apart on the charging circuit board assembly 10, and the three signal connection components 30 are spaced apart between the two charging connection components 20 and arranged in the same row as the two charging connection components 20. By setting the two charging connection components 20 and the three signal connection components 30 in the same row, a stable charging circuit can be established between the charging module and the device to be charged, while realizing multi-channel signal transmission, thereby effectively improving the working efficiency and space utilization of the charging module. In addition, setting the two charging connection components 20 and the three signal connection components 30 in the same row can also reduce the assembly cost of the charging module to a certain extent.

When the point-of-sale terminal is mounted on the charging bracket 50, the charging module electrically connects the point-of-sale terminal and the charging circuit board assembly 10 through at least two charging connection components 20 to form a charging circuit, and electrically connects the point-of-sale terminal and the charging circuit board assembly 10 through at least one signal connection component 30, thereby realizing the transmission of electrical energy and signals between the point-of-sale terminal and the point-of-sale terminal functional base.
[0069] In some embodiments, the charging bracket 50 includes a bracket body, and a first pivot portion is provided between the bracket body and the base body. The pivot axis of the first pivot portion is horizontally arranged, and the bracket body can rotate relative to the base body about the pivot axis of the first pivot portion through the first pivot portion. By providing a first pivot portion with a horizontal pivot axis to connect the bracket body and the base body, the bracket body can rotate relative to the base body about the pivot axis of the first pivot portion. When the point-of-sale terminal is mounted on the bracket body, the staff can adjust the relative position of the point-of-sale terminal on the base body through the first pivot portion, thereby facilitating the staff to interact with customers through the point-of-sale terminal.
[0070] In some embodiments, a second pivot is provided between the first pivot and the base body in this embodiment. The pivot axis of the second pivot is horizontal and perpendicular to the pivot axis of the first pivot. The bracket body can rotate relative to the base body around the pivot axis of the second pivot via the second pivot. By providing a second pivot with a horizontal pivot axis perpendicular to the pivot axis of the first pivot, the first pivot and the base body are connected, allowing the bracket body to rotate relative to the base body around the pivot axis of the second pivot. When the point-of-sale terminal is mounted on the bracket body, staff can adjust the relative position of the point-of-sale terminal on the base body via the first and second pivots, thereby facilitating staff interaction with customers through the point-of-sale terminal.
[0071] In summary, implementing the charging connection component, charging module, and electronic device provided in this embodiment has at least the following beneficial technical effects: The charging module provided in this embodiment movably sets the charging spring pin 22 in the first syringe 21, and sets both ends of the charging spring pin 22 to extend from opposite ends of the first syringe 21, so that the charging connection component 20 can make conductive contact with the device to be charged through one end of the charging spring pin 22, and electrically connect to the charging circuit board assembly 10 through the other end of the charging spring pin 22. Thus, the charging circuit board assembly 10 can achieve electrical connection with the device to be charged only through the charging spring pin 22. That is, the charging circuit board and the device to be charged can directly transmit current through the charging spring pin 22 without passing through the first syringe 21. Since the current does not pass through the first syringe 21 during transmission, the contact impedance between the charging spring pin 22 and the first syringe 21 increases, which will not affect the current transmission of the charging connection component 20. This avoids the charging connection component 20 from overheating due to the increased contact impedance between the charging spring pin 22 and the first syringe 21 during high-current charging, thus improving the user experience.
[0072] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
