Description

Technical Field

[0001] This utility model relates to the field of charging device technology, and specifically to a charging device for detachably connecting a battery. Background Technology

[0002] A charging device is a device containing a battery that can charge other electronic products and is widely used in daily life. According to the EU Regulation (EU) 2023 / 1542 concerning batteries and waste batteries, from 2027 onwards, portable batteries must be able to be disassembled by consumers without the need for special tools. All portable products containing a battery and capable of supplying power to other devices must meet this requirement to be marketed in the EU.

[0003] like Figure 10 and Figure 11 The existing charging device with a detachable battery design mainly includes a base 91, a battery compartment 92, and two elastic metal sheets 93. The elastic metal sheets 93 can be elastically deformed when the cylindrical battery 98 is attached to the battery compartment 92, so that the cylindrical battery 98 can be smoothly inserted into the battery compartment 92 without being unable to be installed due to structural interference. The elastic metal sheets 93 are also electrically connected to the electrodes 981 of the cylindrical battery 98 through an electrical connection part 931 to conduct electricity.

[0004] However, as Figure 11 As shown, under this structural design, the electrical connection part 931 can only contact the electrode 981 in a point-to-point manner to achieve electrical connection. However, different battery suppliers may still have size differences in cylindrical batteries of the same specifications. Size differences can lead to poor contact and failure to conduct electricity smoothly at the point contact position between the electrical connection part 931 and the electrode 981. Therefore, the battery detachable design of the existing charging device needs to be improved. Utility Model Content

[0005] To address the problem that existing charging devices with removable batteries using point contact are prone to poor contact or even loss of conductivity due to dimensional tolerances of cylindrical batteries, this application provides a charging device that can effectively improve this problem.

[0006] This utility model discloses a charging device configured for detachably connecting to a cylindrical battery, the cylindrical battery having two electrodes. The charging device includes: a housing having a receiving groove; a support member fixed within the receiving groove of the housing; two conductive seats spaced apart within the receiving groove and located between the support member and the housing; two connecting members, each having a connected conductive portion and a plug-in portion, wherein the conductive portion is used for electrically connecting to a corresponding electrode of the cylindrical battery, and the plug-in portion passes through the support member and is detachably plugged into a corresponding conductive seat; and a circuit board assembly disposed within the receiving groove, located between the support member and the housing, and electrically connected to the two conductive seats.

[0007] By utilizing the aforementioned technical features, during use, the two connectors are first attached to the two electrodes of the cylindrical battery via welding or snap-fitting to ensure a secure electrical connection. Then, the cylindrical battery is installed onto the carrier, allowing the insertion portion to pass through the carrier and engage with the corresponding conductive base. This ensures the cylindrical battery reliably supplies power to the circuit board assembly and can further power external electronic devices. Therefore, this charging device provides a removable battery design while ensuring good conductivity, reliably supplying power to external devices, and effectively improving upon the problems of existing charging devices.

[0008] In the aforementioned charging device, the insertion portion of each connector and the corresponding conductive base engage and make surface contact during insertion. In the aforementioned charging device, each conductive base includes an elastic clip portion; when the insertion portion of each connector is inserted into the elastic clip portion of the corresponding conductive base, the elastic clip portion is first opened by the insertion portion and then returns to its original position to complete the engagement.

[0009] In the aforementioned charging device, the plug portion of the connector is provided with a first engaging structure, and the corresponding elastic clip portion of the conductive base is provided with a second engaging structure. The first engaging structure and the second engaging structure are matching concave-convex structures, thereby engaging with each other.

[0010] In the aforementioned charging device, the conductive base includes a base having a substantially C-shaped cross-section, the elastic clip extending from the base, and the corresponding connector's insertion portion engaging with the portion where the base and the elastic clip are connected.

[0011] In the aforementioned charging device, the outer edge of the carrier matches the inner surface of the trough, so that the two conductive seats and the circuit board assembly are enclosed between the carrier and the outer casing.

[0012] In the aforementioned charging device, the carrier is provided with two slots spaced apart, each slot being for the insertion portion of one of the corresponding connectors to pass through.

[0013] The charging device described above includes a top cover that can be fitted onto the outer casing. The top cover and the carrier are attracted to each other through at least one magnetic component, causing the top cover to tend to fit onto the outer casing.

[0014] The charging device described above includes a top cover that can be fitted onto the outer casing. The top cover is provided with at least one first magnetic component, and the carrier is provided with at least one second magnetic component. The second magnetic component can attract the first magnetic component, causing the top cover to tend to fit onto the outer casing.

[0015] The charging device described above has a length direction, the upper cover is provided with two first magnetic components spaced apart, the carrier is provided with two second magnetic components spaced apart, and each of the first magnetic components and each of the second magnetic components extends along the length direction.

[0032] Example

[0033] This embodiment provides a charging device, a preferred embodiment of which is, for example... Figures 1 to 3 As shown, it includes a housing 10, a carrier 20, two conductive bases 30, two connectors 40, and a circuit board assembly 50.

[0034] Among them, such as Figures 2 to 5 As shown, the outer casing 10 has a receiving groove 11; the carrier 20 is fixed in the receiving groove 11 of the outer casing 10; two conductive seats 30 are disposed at intervals in the receiving groove 11 and are located between the carrier 20 and the outer casing 10; each connector 40 is used to electrically connect to one of the corresponding electrodes 81 of a cylindrical battery 80, i.e. Figure 5 As shown, the two connectors 40 are electrically connected to the two electrodes 81 of the cylindrical battery 80, respectively, and pass through the carrier 20 and are detachably inserted into one of the corresponding conductive bases 30; the circuit board assembly 50 is disposed in the receiving groove 11, located between the carrier 20 and the outer casing 10, and is electrically connected to the two conductive bases 30. Specifically, as Figure 3 and Figure 6 As shown, each connector 40 is provided with a conductive part 41 and a plug-in part 42 connected together. The conductive part 41 is electrically connected to the corresponding electrode 81, and the plug-in part 42 passes through the carrier 20 and is detachably plugged into the corresponding conductive base 30. In this embodiment, the two conductive bases 30 are plugged into the circuit board assembly 50, and the connector 40 is in the form of a sheet, but is not limited thereto.

[0035] By utilizing the aforementioned technical features, during use, the two connectors 40 are first attached to the two electrodes 81 of the cylindrical battery 80 using methods such as welding or snap-fitting to ensure a reliable electrical connection between the two connectors 40 and the cylindrical battery 80. Then, the cylindrical battery 80 and the two connectors 40 are mounted onto the carrier 20, allowing the insertion portions 42 of the two connectors 40 to pass through the carrier 20 and engage with the corresponding conductive bases 30. This ensures that the cylindrical battery 80 reliably supplies power to the circuit board assembly 50 and can further power external electronic products. Therefore, the charging device of this embodiment provides a removable battery design while ensuring good conductivity, reliably supplying power to external devices, effectively improving upon the problems of existing charging devices.

[0036] Furthermore, the charging device of this invention also includes a top cover 60, which is detachably closed onto the housing 10. The user can easily open the top cover 60 to repair or replace the cylindrical battery 80. For example, the top cover 60 and the carrier 20 can be attracted to each other through at least one magnetic component, causing the top cover 60 to tend to close onto the housing 10.

[0037] In a preferred embodiment of this invention, please refer to, as follows: Figures 2 to 4As shown, the charging device has a length direction L. The upper cover 60 is provided with two first magnetic components 61 extending along the length direction L at intervals. The support member 20 is provided with two second magnetic components 21 extending along the length direction L at intervals. Each second magnetic component 21 is positioned opposite to one of the corresponding first magnetic components 61 and can attract each other. In other words, the magnetic polarities of the first magnetic components 61 and the second magnetic components 21 are opposite; for example, the downward-facing side of the first magnetic component 61 is the N pole, while the upward-facing side of the second magnetic component 21 is the S pole, allowing the upper cover 60 to tend to close the outer casing 10. Furthermore, the upper cover 60 and the support member 20 can each be provided with positioning grooves to accommodate and position the first magnetic components 61 and the second magnetic components 21.

[0038] In other embodiments, the first magnetic component 61 and the second magnetic component 21 can also be magnetic buttons or other shaped magnets; alternatively, the upper cover 60 may only have one first magnetic component 61 and the carrier 20 may only have one corresponding second magnetic component 21, while the other side of the upper cover 60 and the carrier 20 may be pivotally connected or have a locking mechanism, which can also achieve the effect of opening the upper cover 60. Furthermore, if the upper cover 60 and / or the carrier 20 contain at least a portion of magnetic material, a magnet can be provided on the other or between the two, which can achieve the effect of the upper cover 60 tending to close onto the outer casing 10.

[0039] If the top cover 60 is simply detachable or detachable from the outer casing 10 without involving any magnetic components, the user can still easily disassemble and assemble the top cover 60 manually, which can also facilitate the maintenance or replacement of the cylindrical battery 80.

[0040] For example Figure 4 and Figure 5 As shown, the outer edge of the carrier 20 matches the shape of the inner surface of the groove 11 of the outer casing 10, so that the two conductive seats 30 and the circuit board assembly 50 are enclosed between the carrier 20 and the outer casing 10. This prevents the user from accidentally contacting the internal circuitry when opening the top cover 60 for maintenance or replacement of the cylindrical battery 80, thus preventing damage to the circuitry or injury, and improving product safety. The carrier 20 can be glued, bonded to the outer casing 10 using high-frequency welding, or secured with screws. Furthermore, in this preferred embodiment, as... Figure 3 , Figure 5 and Figure 6 As shown, the carrier 20 is also provided with two slots 22 at intervals, located near the two ends of the carrier 20. Each slot 22 is for the insertion part 42 of one of the corresponding connectors 40 to pass through, so that the connector 40 can be inserted and connected with the corresponding conductive base 30.

[0041] Figures 6 to 9 The insertion portion 42 between the conductive base 30 and the connector 40 can have different forms. For example... Figures 6 to 9As shown, when the insertion part 42 of each connector 40 of this invention is inserted into the corresponding conductive base 30, they are engaged with each other and in a state of surface contact. This engagement prevents accidental dislodgement and surface contact ensures conductivity reliability, ensuring that the connector 40 and the conductive base 30 can together form the circuit between the cylindrical battery 80 and the circuit board assembly 50.

[0042] For further information, please refer to [example]. Figures 6 to 9 As shown, each conductive base 30 includes a base 31 and an elastic clip portion 32 extending from the base 31. When the insertion portion 42 of each connector 40 is inserted into the elastic clip portion 32 of the corresponding conductive base 30, the elastic clip portion 32 is first opened by the insertion portion 42 and then elastically reset to complete the engagement, so that the connector 40 will not easily fall off the conductive base 30.

[0043] Specifically, this invention provides two engagement methods for the insertion portion 42 of the connector 40 and the conductive base 30, but is not limited to these: one engagement method is as follows: Figure 7 and Figure 8 As shown, the connector 40 has a first engaging structure 421 in its insertion portion 42, and the corresponding conductive base 30 has a second engaging structure 321 in its elastic clip portion 32. The first engaging structure 421 and the second engaging structure 321 are matching concave-convex structures that engage with each other. In this invention, the first engaging structure 421 is a protrusion, and the second engaging structure 321 is a recess that can accommodate the protrusion. When the insertion portion 42 is inserted into the corresponding elastic clip portion 32 of the conductive base 30, the elastic clip portion 32 is first opened by the insertion portion 42, and after reaching the position of the recess, it extends into the second engaging structure 321 to allow the elastic clip portion 32 to elastically reset and complete the engagement. In other embodiments, the protrusion and the recess can be arranged in opposite directions.

[0044] in, Figure 7 The second engaging structure 321 shown is a through hole recessed in the elastic clip portion 32; Figure 8 The second engaging structure 321 shown is a groove whose shape matches the protrusion and is recessed into the inner side wall of the elastic clip portion 32; the first engaging structure 421 and the second engaging structure 321 can also be other structures or shapes, as long as they can enable the insertion portion 42 and the elastic clip portion 32 to complete the insertion and engaging.

[0045] The second method of card combination, such as Figure 6 and Figure 9 As shown, the base 31 of the conductive base 30 has a substantially C-shaped cross-section, and the corresponding insertion portion 42 of the connector 40 can engage with the portion where the base 31 is connected to the elastic clip portion 32. Wherein, as Figure 6 The conductive base 30 shown has a base 31 with a right-angled portion and an overall cross-section that is roughly C-shaped; while Figure 9The conductive base 30 shown has a C-shaped cross-section with a smooth curved surface. Specifically, because the base 31 has a substantially C-shaped cross-section, the portion where the base 31 of the conductive base 30 connects to the elastic clip portion 32 forms a tapered structure, facilitating the engagement of the insertion portion 42. In practice, the insertion portion 42 may have an irregular structure 422, specifically a bent structure or a partially protruding structure, so that when the insertion portion 42 is inserted into the elastic clip portion 32, the elastic clip portion 32 can be opened, and after reaching the portion where the base 31 connects to the elastic clip portion 32, the elastic clip portion 32 is allowed to elastically return to its original position to complete the engagement.

[0046] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the preferred embodiments above, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model should not depart from the spirit and scope of this utility model. Those skilled in the art can also make other changes within the spirit of this utility model for its design, as long as they do not deviate from the technical effect of this utility model. These changes made according to the spirit of this utility model should all be included within the scope of protection claimed by this utility model.
