Examples of implementation

[0008] First, the following will be shown: Fig. Reference is made to the present utility model. This utility model provides a charging base 10. The charging base 10 can supply power to several candle lamps 21. When the power source in the candle lamps 21 is depleted, the candle lamps 21 are placed on the charging base 10, and the charging base 10 can supply power to the candle lamps 21 so that the candle lamps 21 have sufficient energy and can be used separately.

[0009] The charging base 10 comprises a base body 100 and a circuit assembly 200, the circuit assembly 200 being located inside the base body 100. When mounting the candle lamps 21 on the charging base 10 for charging, the candle lamps 21 are placed on the base body 100 and connected to the circuit assembly 200, so that the circuit assembly 200 can supply current to the candle lamps 21.

[0010] With reference to Fig. 1 and Fig. 2 The base body 100 comprises a connected upper housing 110 and a lower housing 120. The upper housing 110 and the lower housing 120 enclose a mounting space 130. The circuit assembly 200 is arranged in the mounting space 130 and connected to the upper housing 110. The lower housing 120 is detachably snapped onto the upper housing 110. Since the circuit assembly 200 can inevitably become damaged after prolonged use, resulting in some candles 21 not being able to be charged simultaneously and thus reducing charging efficiency, the upper housing 110 and the lower housing 120 are designed as a detachable connection in the present embodiment. This allows the circuit assembly 200 to be replaced if damaged, in order to ensure the service life of the entire charging base 10.Of course, the lower housing 120 can also be designed as an inseparable connection with the upper housing 110 if service life is not a factor, for example by a one-piece design of upper housing 110 and lower housing 120.

[0011] It should be noted that the base body 100 in the present embodiment comprises several screws. The opposite ends of the screws are each connected to the upper housing 110 and the lower housing 120, the screws passing through the lower housing 120 and being screwed into the upper housing 110 to fix the upper housing 110 and the lower housing 120.

[0012] With reference to Fig. 1 and Fig. 2. It should be noted that the side of the upper housing 110 facing away from the lower housing 120 has several mounting parts 111. The candle lamps 21 are mounted on the mounting parts 111. When the candle lamps 21 are mounted on the mounting parts 111, the circuit arrangement 200 is connected to the candle lamps 21 to supply current to the candle lamps 21.

[0013] With reference to Fig. 1 and Fig. 2. It should be noted that the mounting parts 111 in the present embodiment are designed as grooves 112. The shape of the grooves 112 corresponds to the shape of the base of the candle lamps 21. The base of each groove 112 is provided with a first through-hole 113 and two second through-holes 114. Substructures of the circuit arrangement 200 can penetrate the first through-hole 113 and the two second through-holes 114 in order to be connected to the candle lamps 21 and to supply current to the candle lamps 21 from the charging base 10.

[0014] With reference to Fig. 1 and Fig. 2. It should be noted that the number of assembly parts 111 in the present embodiment is twelve. In other embodiments, the number of assembly parts 111 may be two, four, six, or another number. Therefore, the present utility model does not impose any specific limitation regarding the number of assembly parts 111.

[0015] With reference to Fig. 2 and Fig. The circuit arrangement 200 comprises a printed circuit board 210 and several metal sheets 220. The several metal sheets 220 are electrically connected to the printed circuit board 210. The several metal sheets 220 pass through the first through-hole 113 and the two second through-holes 114, are located in each groove 112, and can supply current to the candle lamps 21. The printed circuit board 210 is electrically connected to a charging port 211. The charging port 211 can be connected to a power source. After the power source is connected to the printed circuit board 210, the power supply to the metal sheets 220 is ensured. When the candle lamps 21 are connected to the metal sheets 220, the charging socket 10 can supply current to the candle lamps 21.

[0016] It should be noted that the number of metal sheets 220 corresponds to the number of assembly parts 111. In the present embodiment, the number of metal sheets 220 is twelve. In other embodiments, the number of metal sheets 220 is set at six when the number of assembly parts 111 is six. Therefore, the present utility model does not impose any specific limitation regarding the number of metal sheets 220.

[0017] The metal sheets 220 comprise first metal sheets 221 and second metal sheets 222. The first metal sheets 221 and the second metal sheets 222 are insulated from each other. Of the first metal sheets 221 and the second metal sheets 222, one is positive metal sheet and the other is negative metal sheet. For example, in the present embodiment, the first metal sheets 221 are configured as positive metal sheets and the second metal sheets 222 as negative metal sheets. The first metal sheets 221 are annular, and the second metal sheets 222 are cylindrical, with the second metal sheets 222 arranged on the centerline of the mounting parts 111 and the first metal sheets 221 surrounding the second metal sheets 222.

[0018] It should be noted that in other embodiments, the first metal sheets 221 can also be designed as negative metal sheets and the second metal sheets 222 as positive metal sheets. Therefore, the present utility model does not impose any specific restrictions regarding the concrete design of the first metal sheets 221 and the second metal sheets 222.

[0019] In summary, the circuit arrangement 200 in the present utility model comprises a printed circuit board 210 and several metal sheets 220, wherein the metal sheets 220 include first metal sheets 221 and second metal sheets 222. Of the first metal sheets 221 and the second metal sheets 222, one is positive and the other negative. The first metal sheets 221 surround the second metal sheets 222. When the candle lamps 21 need to be charged, the user can mount them directly onto the mounting parts 111, allowing the charging base 10 to immediately supply power to the candle lamps 21. The user does not need to adjust the candle lamps 21 to a specific angle to mount them onto the mounting parts 111. The process is simple and offers a good user experience.

[0020] With reference to Fig. 2 and Fig. 3. It should be noted that in the present embodiment, the first metal sheets 221 are soldered to the printed circuit board 210. The connection between the first metal sheets 221 and the printed circuit board 210 is made by soldering instead of wire connections, which reduces wire consumption and the risk of wire tangling. It is understandable that the first metal sheets 221 and the printed circuit board 210 could also be connected by wire connections if wire consumption and wire tangling are not a concern. All solutions in which the first metal sheets 221 are connected to the printed circuit board 210 are covered by the scope of protection.

[0021] Further with reference to Fig. 2 and Fig. It should be noted that in the present embodiment, the second metal sheets 222 are also soldered to the circuit board 210. In other embodiments, the second metal sheets 222 can be connected to the circuit board 210 via wire connections. Therefore, the present utility model does not specify any particular restriction regarding the specific connection method between the second metal sheets 222 and the circuit board 210.

[0022] With reference to Fig. 3 and Fig. 4 The first metal sheets 221 have two support columns 223. The two support columns 223 are spaced apart along the radial direction of the first metal sheets 221. The two support columns 223 are supported at the radial ends of the first metal sheets 221. The opposite ends of the support columns 223, in the thickness direction of the base body 100, are soldered to the first metal sheets 221 and the circuit board 210, respectively. The arrangement of two support columns 223 reduces the material consumption for the support columns 223 while simultaneously ensuring current transmission from the circuit board 210 to the first metal sheets 221, thus reducing the manufacturing costs of the entire charging base 10. It is understandable that the support columns 223 can also be arranged in a ring shape along the circumferential direction of the first metal sheets 221 to support the first metal sheets 221 if the reduction of material consumption is not important.All solutions in which the first metal sheets 221 are soldered to the circuit board 210 are covered by the scope of protection.

[0023] It should be noted that when mounting the first metal blades 221 and second metal blades 222 on the upper housing 110, the second metal blades 222 pass through the first through holes 113 and protrude into the grooves 112, the support columns 223 pass through the second through holes 114 accordingly, and the first metal blades 221 are arranged in the grooves 112.

[0024] With reference to Fig. 4. The circuit board 210 comprises a main board 212 and at least two switching strips 213. The main board 212 is electrically connected to the switching strips 213. The main board 212 is located between the two switching strips 213 and at the edge of the socket body 100. The main board 212 is electrically connected to the charging port 211. The charging port 211 is exposed to the outside from the side wall of the socket body 100. Each switching strip 213 has several metal sheets 220. The several metal sheets 220 are spaced apart along the longitudinal direction of the switching strips 213. After the power source is transferred to the main board 212 and the switching strips 213, the metal sheets 220 are energized.The electrical connection between mainboard 212 and two switching strips 213 eliminates the need for the shape of the mainboard 212 to match the shape of the socket body 100, thus reducing the material consumption of the mainboard 212 and lowering the manufacturing costs of the charging socket 10.

[0025] With reference to Fig. 4. The switching strips 213 have several spaced-apart screw connections 214 along their longitudinal direction. The screw connections 214 extend through the switching strips 213 and the upper housing 110 in the thickness direction of the switching strips 213 to fix the switching strips 213 to the upper housing 110. The lower housing 120 is simultaneously detachably snapped onto the upper housing 110 in the thickness direction of the switching strips 213 and the main board 212. Fixing the switching strips 213 to the upper housing 110 prevents the switching strips 213 from vibrating in the mounting space 130. When the user moves the charging base 10, the components on the switching strips 213 are not damaged by vibrations.Furthermore, fixing the switching strips 213 to the upper housing 110 ensures that the metal plates 220 arranged on the switching strips 213 remain constantly aligned with the first through-holes 113 and the second through-holes 114, so that the metal plates 220 can reliably supply current to the candle lamps 21. It is understandable that the screw connections 214 can be omitted if the potential damage to components and the alignment between the support columns 223 and the second through-holes 114, as well as between the second metal plates 222 and the first through-holes 113, are not critical. All solutions in which the switching strips 213 are arranged in the mounting space 130 are covered by the scope of protection.

[0026] Further with reference to Fig. 4. It should be noted that the screw connections 214 and the metal plates 220 are arranged alternately spaced along the longitudinal direction of the same switching strip 213. The screw connections 214 penetrate the switching strips 213 without damaging the metal plates 220. Since the switching strips 213 are made of a flexible material, the alternating arrangement of the screw connections 214 and the metal plates 220 along the longitudinal direction of the switching strips 213 allows for the maximum number of screw connections 214, which ensures secure fixation of the switching strips 213 to the upper housing 110. This effectively prevents the switching strips 213 from detaching from the upper housing 110 after prolonged use and thus prevents the metal plates 220 from supplying current to the candle lamps 21.It is understandable that the alternating arrangement of the screw connections 214 and the metal plates 220 along the longitudinal direction of the switching strips 213 can be omitted if the detachment of the switching strips 213 from the upper housing 110 is not a concern. For example, several screw connections 214 can be arranged along the longitudinal direction of the switching strips 213 at the ends of the switching strips 213. All solutions in which the screw connections 214 are inserted through the switching strips 213 and the upper housing 110 in the thickness direction of the switching strips 213 are covered by the scope of protection.

[0027] Further with reference to Fig. Figure 4 shows that the side of the upper housing 110 facing the lower housing 120 has first support rings 115 and second support rings 116. The first support rings 115 and the second support rings 116 are located between the upper housing 110 and the switching strips 213. The first support rings 115 and the second support rings 116 are spaced apart from each other. The first support rings 115 and the second support rings 116 enclose annular areas along the circumferential direction of the first metal sheets 221. The first support rings 115 and the second support rings 116 can support the switching strips 213. In addition to fixing the switching strips 213 by the screw connections 214, the first support rings 115 and the second support rings 116 further limit the detachment of the switching strips 213 from the upper housing 110 and prevent deformation of the switching strips 213.Furthermore, the first support rings 115 and the second support rings 116 are aligned with the mounting parts 111, allowing for a maximum number of first support rings 115 and second support rings 116. This ensures that the switching strips 213 rest against the first support rings 115 or the second support rings 116 and do not exhibit any bending of the switching strips 213. It is understood that the first support rings 115 and the second support rings 116 can be omitted if potential deformation of the switching strips 213 is not a concern. All solutions in which the switching strips 213 can be fixed to the upper housing 110 are covered by the scope of protection.

[0028] With reference to Fig. 1 and Fig. The charging socket 10 also includes an indicator light 300. The indicator light 300 is electrically connected to the main board 212. When the charging socket 10 supplies power to the candle lamps 21, the main board 212 simultaneously supplies power to the indicator light 300, causing it to illuminate. Due to the arrangement of the indicator light 300, it illuminates synchronously during the charging of the candle lamps 21, allowing the user to confirm whether the candle lamps 21 are actually charging. If the candle lamps 21 are not charging, the user can readjust their position to ensure safe charging. The process is simple. It is understood that the indicator light 300 can be omitted. All solutions in which the charging socket 10 can supply power to the candle lamps 21 are covered by the scope of protection.

[0029] It should be noted that in the present embodiment, the indicator light 300 changes its color when the candle lamps 21 are fully charged. In other embodiments, the indicator light 300 may be switched off, dimmed, or signal in some other way when the candle lamps 21 are fully charged. Therefore, the present utility model does not specify any particular restriction regarding the specific display mode of the indicator light 300.

[0030] With reference to Fig. Section 5 of the present utility model further provides a candle arrangement 20. The candle arrangement 20 comprises the charging base 10 described above and several candle lamps 21. The candle lamps 21 are mounted on the aforementioned mounting parts 111 and connected to the metal leaves 220, such that the metal leaves 220 supply current to the candle lamps 21 and provide the candle lamps 21 with sufficient energy for separate use.

[0031] With reference to Fig. The 6 candle lamps comprise lamp bases 21, lamp bodies 22, metal contacts 24, and power driver boards 25. The lamp bases 22 are connected to the lamp bodies 23. The metal contacts 24 and the power driver boards 25 are arranged within the lamp bases 22. The metal contacts 24 and the power driver boards 25 are electrically connected to each other, with substructures of the metal contacts 24 projecting beyond the lamp bases 22. The power driver boards 25 are electrically connected to the lamp bodies 23. The metal contacts 24 comprise first metal contacts 26 and second metal contacts 27. The first metal contacts 26 are connected to the first metal sheets 221, and the second metal contacts 27 are connected to the second metal sheets 222. After transferring the power source from the metal sheets 220 to the metal contacts 24, it is passed on to the power driver boards 25.The power driver boards 25 supply the lamp bodies 23 with power, so that the lamp bodies 23 light up.

[0032] Further with reference to Fig.Each candle lamp 21 further comprises two magnetic elements 28. The two magnetic elements 28 are arranged in the lamp base 22. The two magnetic elements 28 are spaced apart from each other along the radial direction of the lamp base 22. When the candle lamps 21 are mounted on the mounting parts 111, the magnetic elements 28 are magnetically attracted to the first metal plates 221, so that the candle lamps 21 are more securely fixed to the mounting parts 111. If the user needs to move the charging base 10 and the candle lamps 21 while the candle lamps 21 are charging, the candle lamps 21 will not detach from the mounting parts 111 due to the action of the magnetic elements 28. It is understood that the two magnetic elements 28 can be omitted if the possibility of the candle lamps 21 detaching from the charging base 10 is not a concern. All solutions in which the candle lamps 21 can be mounted on the charging base 10 are covered by the scope of protection.
