Description

Technical Field

[0001] The present application belongs to the technical field of mobile charging equipment, and in particular, relates to a combined charging device. Background Art

[0002] At present, the constantly changing intelligent mobile devices, such as smart phones, smart watches and tablets, are dedicated to business or personal communication, communication, photography and computing needs. These mobile smart devices are restricted by battery capacity and need to be charged in time to ensure the continuous use of mobile smart devices. Therefore, when people go on business trips, travel, etc., they need to carry chargers.

[0003] With different usage scenarios, mobile smart devices have the need to connect to different devices for data transmission, but the data ports of different devices are different, resulting in compatibility issues of data port connections. Digital docking stations are available on the market to solve the connection compatibility issues of different data ports. Docking stations, also known as port replicators, were originally designed as an external device for laptops. By duplicating or even expanding the ports of laptops, laptops can be conveniently connected to multiple accessories or external devices (such as power adapters, network cables, mice, external keyboards, printers, and external displays) in one stop. Existing docking stations are also gradually becoming popular for use on mobile smart devices, allowing mobile smart devices to connect to other different devices for data transmission through docking stations.

[0004] It can be seen that in order to match the usage scenario, when the user goes out for a long distance, in addition to the charger, the expansion dock must also be carried. However, the charger and expansion dock currently on the market are two completely independent devices that can only be stored separately, which is not conducive to carrying. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a combined charging device to solve the technical problem of the single function of the charger in the prior art.

[0006] To achieve the above purpose, the technical solution adopted by the present application is: to provide a combined charging device, including:

[0007] A charger, provided with a first splicing end for combined connection, wherein the first splicing end is provided with an electrical contact;

[0008] The expansion dock is provided with a second splicing end for connecting with the first splicing end, and the second splicing end is provided with an electrical contact corresponding to the position of the electrical contact;

[0009] The charger and the expansion dock are spliced ​​together to form a whole through the first splicing end and the second splicing end, and the electrical contacts are in synchronous contact with the electrical contacts.

[0010] The combined charging device provided by the present application has the following beneficial effects: compared with the prior art, the combined charging device of the present application includes a charger and an expansion dock, and the charger and the expansion dock are combined components that can be combined and connected to each other, and the two can be combined and connected to form a whole, which is convenient for users to store and carry. Among them, the charger and the expansion dock are respectively provided with a first splicing end and a second splicing end for combined connection, and the first splicing end and the second splicing end are also respectively provided with electrical contacts and electrical contacts in corresponding positions, so that when the charger and the expansion dock are combined and connected through the first splicing end and the second splicing end, the electrical contacts and electrical contacts on the two can be synchronously contacted with each other at the same time to achieve electrical connection, thereby omitting the need for an additional charging cable to be installed between the two, effectively saving space, facilitating use, and improving user experience.

[0011] An improvement is made to the combined connection structure between the charger and the expansion dock, where both the first splicing end and the second splicing end have shape-matched concave and convex parts, so that the contours of the parts where the first splicing end and the second splicing end are spliced ​​together are consistent. This is helpful to limit the splicing direction of the charger and the expansion dock, so as to prevent mistakes when the two are combined and connected.

[0012] In one embodiment, the concave-convex part on the first splicing end includes a first convex part and a first concave part connected adjacently, and a guide rail is provided on the first convex part; the concave-convex part on the second splicing end includes a second convex part and a second concave part connected adjacently, and a guide plate for mounting and cooperating with the guide rail is provided on the second concave part, and the guide plate is horizontally arranged on the second concave part and extends from the second convex part to the side edge of the docking station. In this way, by utilizing the installation connection between the guide plate and the guide rail, the charger and the docking station can be coaxially aligned after being combined and connected in place, and at the same time, the charger and the docking station are locked axially, effectively ensuring the connection effect between the two.

[0013] In one embodiment, the first splicing end is also provided with a surrounding edge arranged around the outer periphery of the first protrusion, and the guide rail is arranged on the surrounding edge; the guide plate is provided with a convex edge arranged around the outer periphery of the guide plate, and the convex edge is used to embed the guide rail. The structure is simple, and the concave and convex structure on the first splicing end and the second splicing end is used to realize the installation connection between the guide rail and the guide plate, effectively limiting the combination mode of the charger and the docking station, and locking the charger and the docking station axially so that the two are spliced ​​and fixed.

[0014] In one embodiment, the electrical contact is arranged on the side of the first protrusion; the electrical contact point is arranged on the side of the second protrusion and is located above the connection between the guide plate and the second protrusion; when the first protrusion and the second protrusion are on the same horizontal plane, the electrical contact and the electrical contact point are arranged facing each other and have corresponding positions. In this way, when the charger is combined with the docking station, the side of the first protrusion and the side of the second protrusion are close to each other, so that the electrical contact and the electrical contact point are in contact with each other, and the electrical connection is achieved synchronously.

[0015] The electrical connection structure of the charging device is improved, and the combined charging device also includes a protection mechanism for protecting the electrical contacts, the protection mechanism includes a trigger and a shielding assembly for shielding the electrical contacts, the trigger is arranged on the second spliced ​​end of the docking station, and the trigger is used to drive the shielding assembly to move so that the electrical contacts are exposed. In this way, the structure of the entire protection mechanism is simple, easy to process and manufacture, with high trigger sensitivity, and effectively ensures the protection effect of the electrical contacts.

[0016] In one embodiment, the shielding assembly includes a spring and a movable block, wherein the movable block is arranged on the first splicing end and connected to the spring; the movable block is provided with a protective cover for sleeve-fitting the electrical contact, and the electrical contact is accommodated in the protective cover; the trigger member is a top block arranged on the second splicing end, and the top block is used to push the movable block to move so that the electrical contact is exposed from the protective cover, which is convenient for contact with the electrical contact to achieve electrical connection.

[0017] In one embodiment, the protective cover is a hollow sleeve protruding from the movable block, and the sleeve length of the protective cover is not less than the electrical contact, so that the electrical contact can be completely accommodated in the protective cover, effectively preventing foreign objects from contacting the electrical contact, thereby improving the protection effect on the electrical contact.

[0018] In one embodiment, the movable block is provided with a positioning groove for the trigger member to be embedded, and the positioning groove corresponds to the position of the trigger member, so that the trigger member can accurately and smoothly push the movable block, effectively ensuring the triggering effect.

[0019] Another improvement is made to the combined connection structure between the charger and the expansion dock, where the end surfaces of the first splicing end and the second splicing end are respectively provided with magnetic modules that can be magnetically attracted to each other. The structure is simple, and when the charger and the expansion dock are combined and connected, the magnetic module on the first splicing end and the magnetic module on the second splicing end can be directly magnetically attracted to each other to achieve the combined connection of the charger and the expansion dock.

[0045] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0046] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0047] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0048] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0049] Currently, the chargers and docking stations on the market are two independent devices that can only be stored separately, which is not convenient for carrying around.

[0050] In addition, when the charger and the docking station need to be connected, for example, some expansion interfaces on the docking station, such as the HDMI interface, require a certain amount of power to operate normally. At this time, it is necessary to connect a charging cable between the charger and the docking station so that the charger can power the docking station to meet the usage requirements.

[0051] It can be seen that since the charger and the docking station are two independent devices, an external charging cable is required to achieve an electrical connection between the two. This brings inconvenience to travel and requires users to carry two independent devices as well as a charging cable specially adapted to connect the two. In actual applications, it is even necessary to carry two or more cables, one for the electrical connection between the charger and the docking station, and the rest for the connection between the docking station and other external devices. As a result, more auxiliary devices need to be carried during the entire trip, affecting the user experience.

[0052] Here, the embodiment of the present application provides a new type of combined charging device, which allows the charger and the expansion dock to be combined together, which can not only save the connection cables between them and facilitate the connection and use, but also meet the requirements of easy storage when traveling, and effectively solve the technical problems of traditional chargers with single functions and complex external devices. It is now described in detail.

[0053] Please also read Figure 1 , Figure 2 and Figure 3 The combined charging device includes a charger 100 and a docking station 200 .

[0054] In this embodiment, the charger 100 is similar to a commonly used charging head, and has a charging terminal 101 for connecting to a power source. The charging terminal 101 can preferably be arranged on the charger 100 in a retractable structure. Figure 1 As shown, the charger 100 has a receiving slot 102 capable of receiving the charging terminal 101. The charging terminal 101 is arranged on the charger 100 in a movable manner (such as a rotating shaft connection) so that the charging terminal 101 can be received in the receiving slot 102. The charging terminal 101 can be manually pulled out from the receiving slot 102 so as to be plugged into a power socket.

[0055] In addition, the charger 100 also has a data port 103 for connecting to an external device. Figure 2 As shown, the charger 100 may preferably be provided with at least two data ports 103 , and the types of the data ports 103 may include but are not limited to TYPE-C, USB, etc., so as to adapt to different mobile smart terminals for data connection.

[0056] For the structure on the docking station 200, such as Figure 3 As shown, the expansion dock 200 is provided with multiple expansion interfaces 201, which may include but are not limited to USB, TYPE-C, HDMI, DP, RJ45 and other interfaces. Each expansion interface 201 may include one or more, which can be specifically set according to the volume or available space of the expansion dock 200, and is not specifically limited here.

[0057] In the embodiments of this application, please refer to Figure 2 , Figure 3 and Figure 4 ( Figure 2 The dotted frame portion is the first splicing end 1, Figure 3 and Figure 4 The dotted frame portion is the second splicing end 2, and the expressions in the remaining figures below are the same). The charger 100 is provided with a first splicing end 1 for combined connection with the expansion dock 200, and the first splicing end 1 is provided with an electrical contact 10 for electrical connection.

[0058] In coordination, the docking station 200 is provided with a second splicing end 2, which is used to be combined and connected with the first splicing end 1, and the second splicing end 2 is provided with an electrical contact 20. When the charger 100 is combined and connected with the docking station 200, the electrical contact 20 corresponds to the position of the electrical contact 10.

[0059] In this way, the charger 100 and the docking station 200 can be connected to form a whole through the first splicing end 1 and the second splicing end 2, which is convenient for users to store. At the same time, the electrical contact 10 on the first splicing end 1 and the electrical contact 20 on the second splicing end 2 are also synchronously contacted when the charger 100 and the docking station 200 are combined and connected to achieve electrical connection between the two.

[0060] Compared with the prior art, the combined charging device provided in the embodiment of the present application includes a charger 100 and a docking station 200. The charger 100 and the docking station 200 are assemblies that can be combined and connected to each other. The two can be combined and connected to form a whole, which is convenient for users to store and carry.

[0061] The charger 100 and the docking station 200 are respectively provided with a first splicing end 1 and a second splicing end 2 for combined connection, and the first splicing end 1 and the second splicing end 2 are respectively provided with an electric contact 10 and an electric contact point 20 at corresponding positions, so that when the charger 100 and the docking station 200 are combined and connected through the first splicing end 1 and the second splicing end 2, the electric contacts 10 and the electric contacts 20 on the two can simultaneously contact each other synchronously to achieve electrical connection.

[0062] In this way, the need for an additional charging cable to connect the two can be omitted, saving space and facilitating use. This allows users to reduce the number of devices they carry when traveling (such as the number of cables, etc.), effectively improving the user experience.

[0063] In addition, if the docking station 200 has different combinations of expansion interfaces 201, it is convenient to use them in different usage scenarios. However, since the number and type of expansion interfaces 201 on the docking station 200 are finalized at the factory and cannot be changed later, it limits actual use, so users may need to carry multiple docking stations 200 for simultaneous use.

[0064] In order to meet the usage requirements of users, in the combined charging device provided in the embodiment of the present application, since the charger 100 and the expansion dock 200 are components that can be combined and connected to each other, multiple styles of expansion docks 200 can be provided, so that the corresponding style of expansion dock 200 can be selected according to usage requirements to be combined and connected for use with the charger 100, thereby improving the applicability of the charging device.

[0065] In this embodiment, if Figure 5As shown, there are different styles of docking stations 200, which can be understood here as different styles of docking stations 200 are provided with different types of expansion interfaces 201. Each style of docking station 200 is provided with a second splicing end 2 with the same structure. Users can choose a corresponding style of docking station 200 according to actual use requirements, and connect the second splicing end 2 with the first splicing end 1 on the charger 100 to form a complete charging device for overall use.

[0066] For the combined connection structure between the charger 100 and the docking station 200, in one embodiment of the present application, please refer to Figure 6 The first splicing end 1 and the second splicing end 2 both have a shape-matched concave-convex portion M so that the contours of the parts where the first splicing end 1 and the second splicing end 2 are spliced ​​together are consistent.

[0067] In this embodiment, the concave and convex parts M on the first splicing end 1 and the second splicing end 2 are high and low wave parts with matching shapes. In this way, the combination of the first splicing end 1 and the second splicing end 2 is unique, which is conducive to limiting the splicing direction of the charger 100 and the docking station 200, so as to prevent mistakes when the two are combined and connected.

[0068] In the embodiments of this application, please refer to Figure 6 , Figure 7 and Figure 8 The concave-convex portion Ma on the first splicing end 1 includes a first convex portion 11 and a first concave portion 12 that are adjacent to each other, and the concave-convex portion Mb on the second splicing end 2 includes a second convex portion 21 and a second concave portion 22 that are adjacent to each other, and the shapes of the first convex portion 11 and the first concave portion 12 on the first splicing end 1 are consistent with each other.

[0069] It can be understood here that when combined and connected, the positions of the first protrusion 11 and the second recess 22 correspond, and the positions of the first recess 12 and the second protrusion 21 correspond, so that the combination of the first splicing end 1 and the second splicing end 2 is unique, and the splicing parts can complement each other.

[0070] For details, please refer to Figure 7 and Figure 8 The first protrusion 11 is provided with a guide rail 13. The second recess 22 is provided with a guide plate 23 for installation and cooperation with the guide rail 13. The guide plate 23 is arranged horizontally on the second recess 22 and extends from the second protrusion 21 to the side edge of the entire docking station 200. In this way, by utilizing the installation connection between the guide plate 23 and the guide rail 13, the charger 100 and the docking station 200 can be coaxially aligned after being assembled and connected in place, and at the same time, the charger 100 and the docking station 200 are locked in the axial direction, effectively ensuring the connection effect between the two.

[0071] During the combined connection, since the guide plate 23 is disposed transversely on the second splicing end 2 of the docking station 200, and the guide rail 13 is disposed on the first splicing end 1 of the charger 100 to cooperate therewith, the charger 100 and the docking station 200 can be relatively displaced in the radial direction, so that the charger 100 slides from the side of the docking station 200 with the first splicing end 1 onto the second splicing end 2, so that the guide plate 23 slides into the guide rail 13 and moves along the guide rail 13, so that the first splicing end 1 on the charger 100 and the second splicing end 2 on the docking station 200 can be spliced ​​into place.

[0072] During disassembly, the above-mentioned reverse operation can be adopted to separate the guide plate 23 from the guide rail 13 , so that the first splicing end 1 on the charger 100 and the second splicing end 2 on the docking station 200 are separated from each other.

[0073] For the specific structure of the guide rail 13 and the guide plate 23, please refer to Figure 8 and Fig. 9 The first splicing end 1 is also provided with a peripheral edge 14 arranged around the outer periphery of the first protrusion 11, and the guide rail 13 is arranged on the peripheral edge 14. The guide plate 23 is provided with a flange 231 arranged around the outer periphery of the guide plate 23, and the flange 231 is used to embed the guide rail 13.

[0074] In this embodiment, if Fig. 9 As shown, the guide rail 13 is preferably a convex rail on the inner wall of the surrounding edge 14. When the charger 100 is combined and connected with the docking station 200, the convex edge 231 on the outer periphery of the guide plate 23 can be embedded in the groove N between the convex rail and the surface of the first protrusion 11.

[0075] In this way, the structure is simple, and the concave-convex structure on the first splicing end 1 and the second splicing end 2 is used to realize the installation connection between the guide rail 13 and the guide plate 23, effectively limiting the combination mode of the charger 100 and the expansion dock 200, and locking the charger 100 and the expansion dock 200 axially so that the two are spliced ​​and fixed.

[0076] In one embodiment of the present application, please refer to Figure 7 and Figure 8 The electric contact 10 is arranged on the side of the first protrusion 11. The electric contact 20 is arranged on the side of the second protrusion 21 and is located above the connection between the guide plate 23 and the second protrusion 21.

[0077] When the first protrusion 11 and the second protrusion 21 are on the same horizontal plane, the electrical contact 10 and the electrical contact point 20 are arranged facing each other and in corresponding positions.

[0078] In this way, when the charger 100 and the docking station 200 are combined and connected, the side of the first protrusion 11 and the side of the second protrusion 21 are brought close to each other by utilizing the connection method of the guide plate 23 and the guide rail 13, so that the electrical contact 10 and the electrical contact 20 are in contact with each other, thereby achieving electrical connection synchronously.

[0079] The radial locking structure when the charger 100 and the docking station 200 are combined and connected includes but is not limited to the following implementation forms:

[0080] In one embodiment of the present application, please refer to Fig.10 and Fig.11 Magnetic components 51 are respectively provided on the side of the first protrusion 11 and the side of the second protrusion 21. The magnetic components 51 can preferably be magnets that can be magnetically attracted to each other, or magnets and metal parts that can be magnetically attracted, such as iron. Fig.10 and Fig.11 As shown, the magnetic attraction component 51 can be understood as a magnetic element disposed inside the side of the first protrusion 11 and the side of the second protrusion 21, or a magnetic surface on the surface of the side of the two. In this way, the side of the first protrusion 11 and the side of the second protrusion 21 can be magnetically attracted to each other, and the charger 100 and the docking station 200 are fixed to each other in the radial direction.

[0081] In another embodiment of the present application, please refer to Fig.12 and Fig.13 , buckle holes 52 are provided on both sides of the first protrusion 11; correspondingly, flanges 53 are provided on both sides of the guide plate 23 on the second joint end 2, and buckle blocks 54 are provided on the flanges 53 for buckling with the buckle holes 52. In this way, when the charger 100 and the docking station 200 are combined and connected, the side of the first protrusion 11 and the side of the second protrusion 21 can be buckled, and the charger 100 and the docking station 200 are also fixed to each other in the radial direction.

[0082] Regarding the electrical connection structure on the combined charging device of the present application, in actual applications, since the electrical contacts 10 on the charger 100 need to be arranged on the surface of the first splicing end 1, it is convenient to synchronously contact with the electrical contacts 20 arranged on the docking station 200 when the charger 100 is combined and connected with the docking station 200. Therefore, the electrical contacts 10 are easily in a protruding and exposed state. In the case of non-electrical connection, the electrical contacts 10 are easy to contact with foreign objects and short circuit failures are easy to occur; moreover, in the charging device provided in the embodiment of the present application, the charger 100 and the docking station 200 are combined and connected by the above-mentioned combination method. When the two are combined and connected, the surfaces of the first splicing end 1 and the second splicing end 2 are easy to rub against each other, causing the electrical contacts 10 to be easily scratched.

[0083] Here, in one embodiment of the present application, the combined charging device of the present application also includes a protection mechanism for protecting the electric contact 10, which is used to prevent the electric contact 10 from accidentally contacting with foreign objects and causing short circuit failures. At the same time, it can also prevent foreign objects from directly rubbing against the electric contact 10, thereby preventing the electric contact 10 from being easily worn.

[0084] Please also read Fig.14 , Fig.15 and Fig.16 The protection mechanism includes a trigger 3 and a shielding component 4 for shielding the electric contact 10. The shielding component 4 is arranged on the first splicing end 1 of the charger 100. The shielding component 4 is used to shield the electric contact 10 to prevent the electric contact 10 from being exposed.

[0085] The trigger member 3 is disposed on the second splicing end 2 of the docking station 200 , and the trigger member 3 is used to drive the shielding assembly 4 to move so that the electrical contact 10 can be exposed to contact the electrical contact point 20 .

[0086] Under normal conditions, the shielding component 4 can be used to shield the electric contact 10 to prevent the electric contact 10 from being exposed, and to prevent the electric contact 10 from being easily short-circuited or easily damaged by scratches from foreign objects. When the charger 100 and the docking station 200 are combined and connected, as the first protrusion 11 on the first splicing end 1 and the second protrusion 21 on the second splicing end 2 approach each other, the trigger member 3 on the second splicing end 2 can trigger the shielding component 4 on the first splicing end 1 to move, so that the electric contact 10 can be exposed and contact the electric contact 20 to achieve electrical connection.

[0087] In the embodiments of this application, please refer to Fig.15 and Fig.16 The shielding assembly 4 includes a spring (not shown) and a movable block 41. The movable block 41 is arranged on the first splicing end 1 of the charger 100 and connected to the spring. The movable block 41 is provided with a protective cover 42 for sleeve-fitting the electric contact 10. The electric contact 10 is accommodated in the protective cover 42. Specifically, the movable block 41 and the spring are arranged on the first protrusion 11 of the first splicing end 1. The spring can reset the movable block 41 so that the protective cover 42 remains covered on the electric contact 10.

[0088] The protective cover 42 may preferably be a hollow sleeve protruding from the movable block 41, and the sleeve length of the protective cover 42 is not less than the electrical contact 10, so that the electrical contact 10 can be completely accommodated in the protective cover 42. When the movable block 41 and the protective cover 42 are driven to move by the trigger member 3, the electrical contact 10 can extend from the sleeve opening of the protective cover 42 to contact the electrical contact 20 on the docking station 200.

[0089] Please also read Fig.14 and Fig.16The trigger member 3 is preferably a top block arranged on the second splicing end 2, and the top block is used to push the movable block 41 to move when the charger 100 is combined and connected with the expansion dock 200, so that the movable block 41 simultaneously drives the protective cover 42 to shift, so that the electrical contact 10 can be exposed from the protective cover 42.

[0090] In this way, the push block on the docking station 200 pushes the movable block 41 to shift, so that the electrical contact 10 is exposed from the protective cover 42 and contacts the electrical contact 20, so that the charger 100 and the docking station 200 are electrically connected when they are combined and connected. When the charger 100 and the docking station 200 are separated, the force of the trigger member 3 disappears, allowing the compressed spring to recover and drive the movable block 41 to reset, so that the protective cover 42 remains covered on the electrical contact 10.

[0091] It can be seen that the structure of the entire protection mechanism is very simple, easy to process and manufacture, has high trigger sensitivity, and effectively ensures the protection effect of the electrical contact 10.

[0092] Based on the above, in one embodiment of the present application, please refer to Fig.14 , Fig.15 and Fig.16 The movable block 41 is provided with a positioning groove 43 for the top block to be embedded, and the positioning groove 43 corresponds to the position of the trigger member 3. The trigger member 3 can preferably be a cone structure, which is conducive to automatically aligning with the positioning groove 43 when the charger 100 and the docking station 200 are combined in the above manner, and easily sliding into the positioning groove 43.

[0093] Thus, when the charger 100 is combined and connected with the docking station 200 , the trigger member 3 can automatically align and embed into the positioning groove 43 to push the movable block 41 , so that the movable block 41 drives the protective cover 42 to move, thereby exposing the electrical contact 10 from the protective cover 42 .

[0094] On the one hand, the positioning groove 43 on the movable block 41 can be automatically aligned with the trigger member 3, so that the trigger member 3 can accurately and smoothly push the movable block 41, effectively ensuring the triggering effect.

[0095] On the other hand, since the electrical contact 20 and the top block are both located on the side wall of the second protrusion 21 on the second splicing end 2, and the trigger member 3 is protruding on the side wall of the second protrusion 21, the positioning groove 43 on the movable block 41 can also form a height difference, so that when the trigger member 3 is embedded in the positioning groove 43, the electrical contact 20 is also closely attached to the electrical contact 10, thereby improving the stability of the electrical connection.

[0096] Regarding the arrangement structure of the above-mentioned spring, in one embodiment of the present application, as Fig.16As shown, a mounting groove 44 is provided on the first splicing end 1 of the charger 100, and specifically, the mounting groove 44 can be provided on the first convex portion 11 of the first splicing end 1, and the electric contact 10 and the movable block 41 are both arranged in the mounting groove 44. One end of the spring is fixed to the bottom of the mounting groove 44, and the other end of the spring is connected to the movable block 41. In this way, the movable block 41 and the spring are both accommodated in the first convex portion 11, which is conducive to preventing foreign objects such as sand from entering the mounting groove 44, causing the spring to be easily stuck and affecting the triggering effect of the protection mechanism.

[0097] Regarding the combined connection structure between the charger 100 and the docking station 200, in addition to the above-mentioned connection method, in another embodiment of the present application (not shown in the figure), magnetic attraction modules (not shown in the figure) that can be magnetically attracted to each other can be respectively provided on the end surfaces of the first splicing end 1 and the second splicing end 2.

[0098] In this way, the structure is simple. When the charger 100 and the docking station 200 are combined and connected, the magnetic attraction module on the first splicing end 1 and the magnetic attraction module on the second splicing end 2 can be directly magnetically attracted to each other, thereby realizing the combined connection of the charger 100 and the docking station 200.

[0099] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
