Detailed implementation manners

[0028] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of non-conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back, inside, outside, top, bottom...) in the embodiments of the present invention are only used to explain the relative position relationship between components in a specific posture (as shown in the accompanying drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0030] It should also be noted that when an element is referred to as "fixed to" or "disposed on" another element, the element can be directly on the other element or there may be an intermediate element therebetween. When an element is referred to as "connected to" another element, it can be directly connected to the other element or there may be an intermediate element therebetween.

[0031] Please refer to Figures 1 to 9 , a charging device 10 provided by an embodiment of the present utility model includes a housing 12 and a charging assembly 14 located inside the housing 12. The charging assembly 14 is used to be electrically connected to an electronic device such as a mobile phone, etc., so as to charge the electronic device.

[0032] The charging device 10 can be a charger or a power bank. That is to say, the charging device 10 can charge the electronic device by an external power supply, or it can be a device with its own power supply and can charge the electronic device without an external power supply.

[0033] In the present application, the charging assembly 14 includes an energy storage member 16 located inside the housing 12. The energy storage member 16 is used to store electric energy to supply power to the electronic device. When the energy storage member 16 forms an electrical connection with the electronic device, the charging device 10 can use the energy storage member 16 to charge the electronic device, breaking away from the bondage of the external power supply and facilitating use in an outdoor environment.

[0034] The specific type of the energy storage member 16 is not limited, such as a battery, a capacitor, etc. In this embodiment, the energy storage member 16 is a rechargeable battery, achieving the effect of recycling use.

[0035] It can be understood that the energy storage member 16 forms an electrical connection with the electronic device, which can be in a wired connection manner or a wireless connection manner.

[0036] In this embodiment, the charging assembly 14 further includes a charging coil 18 located inside the housing 12. The charging coil 18 is electrically connected to the energy storage member 16. The charging device 10 can utilize the effect that the charging coil 18 forms an electrical connection with an electronic device having a wireless charging function, without the user having to carry an extra wire, facilitating the user's use.

[0037] The charging assembly 14 further includes a plurality of circuit boards 20 located inside the housing 12. The charging coil 18 is electrically connected to the energy storage member 16 through the circuit boards 20.

[0038] In this embodiment, at least two circuit boards 20 are provided inside the housing 12. The at least two circuit boards 20 are arranged along the thickness direction of the housing 12, and an air flow channel 22 is formed between adjacent circuit boards 20. Specifically, the number of the circuit boards 20 is two. The two circuit boards 20 are arranged along the thickness direction of the housing 12, making full use of the space of the housing 12 in the thickness direction. At the same time, an air flow channel 22 is formed between the two circuit boards 20 to prevent the two circuit boards 20 from fitting together, which can increase the contact area between the circuit boards 20 and the air, thereby enhancing the heat dissipation effect of the circuit boards 20.

[0039] The charging assembly 14 further includes a magnetic attraction member 24 located inside the housing 12. The magnetic attraction member 24 surrounds the outside of the charging coil 18 to form a magnetic attraction cooperation effect with the electronic device, so that the electronic device is tightly attached to the housing 12 of the charging device 10, reducing the risk that the electronic device separates from the charging device 10 during the charging process and affecting the charging effect.

[0040] Specifically, the number of the magnetic attraction members 24 is multiple. The multiple magnetic attraction members 24 are arranged along the circumferential direction of the charging coil 18 and form an unclosed annular structure to avoid the formation of eddy current phenomena during the charging process.

[0041] In one embodiment, the housing 12 includes a side wall 26, a front panel 28 and a back panel respectively provided on opposite sides of the side wall 26. The back panel 30 and the front panel 28 are spaced apart and opposite to each other. The side wall 26 is annular, and the back panel 30, the front panel 28 and the surrounding wall enclose a receiving cavity 32. The charging assembly 14 is located inside the receiving cavity 32. During the charging process, the front panel 28 contacts the electronic device, and the charging coil 18 and the magnetic attraction member 24 are arranged close to the front panel 28.

[0042] Specifically, the charging coil 18 of the charging assembly 14 is thermally conductively connected to the front panel 28, and the energy storage member 16 is thermally conductively connected to the back panel 30. The front panel 28 and the back panel 30 are preferably made of materials with good thermal conductivity, such as metals, to enhance the thermal conduction efficiency. In some embodiments, a thermal conductive silicone grease is provided between the charging coil 18 and the front panel 28 to enhance the thermal conduction efficiency.

[0043] A receiving portion 34 is recessed on the inner side and the side close to the receiving cavity 32 of the front panel 28, and the charging coil 18 and the magnetic attraction member 24 are installed in the receiving portion 34.

[0044] The specific connection manner between the side wall 26 and the front panel 28 and the back panel 30 is not limited, such as snap fit, mechanical connection, glue connection, etc. In this embodiment, the back panel 30 is fixedly glued to the side wall 26, and the front panel 28 is snap-fitted with the side wall 26, thereby forming a detachable connection effect, which is convenient for repairing, replacing, etc. the charging assembly 14 inside the housing 12.

[0045] On one side of the panel 28 away from the back plate 30, there is a soft rubber layer 35. When the electronic device is in the charging process and contacts the soft rubber layer 35, it can prevent the electronic device from directly contacting the panel 28. The soft rubber layer 35 can play a role in protecting the electronic device and reducing the risk of the electronic device being scratched.

[0046] Preferably, the soft rubber layer 35 is made of a colloid with good thermal conductivity to reduce the influence of the soft rubber layer 35 on the heat transfer between the panel 28 and the electronic device.

[0047] In one embodiment, the charging device 10 further includes a temperature reduction component 36. The temperature reduction component 36 is located inside the housing 12 and is in thermal conduction connection with the housing 12. During the working process of the temperature reduction component 36, it can reduce the temperature of the housing 12. And when the electronic device is in the charging process, it will contact the housing 12 under the action of the magnetic attraction member 24. Therefore, the electronic device can transfer the heat generated during the charging process to the housing 12 of the charging device 10, thereby reducing the temperature of the electronic device, and further reducing the influence of the heat generated by the electronic device during the charging process on the charging efficiency and prolonging the holding time of the fast charging mode.

[0048] Specifically, when the electronic device is in the charging process, the electronic device contacts the panel 28 of the housing 12, and the temperature reduction component 36 is in thermal conduction connection with the panel 28 of the housing 12 to reduce the thermal conduction path between the temperature reduction component 36 and the electronic device, so as to improve the temperature reduction effect of the temperature reduction component 36 on the electronic device.

[0049] It can be understood that the temperature reduction component 36 can be directly in thermal conduction connection with the housing 12, or indirectly form a thermal conduction connection with the housing 12 through a heat conduction element.

[0050] The temperature reduction component 36 includes a refrigerating member 38 and a heat conducting member 40 located inside the housing 12. The charging component 14 is in thermal conduction connection with the housing 12, and the refrigerating member 38 is in thermal conduction connection with the charging component 14 through the heat conducting member 40. Specifically, the charging coil 18 of the charging component 14 is in thermal conduction connection with the housing 12, and the refrigerating member 38 is electrically connected to the circuit board 20 and is in thermal conduction connection with the charging coil 18 and the magnetic attraction member 24 through the heat conducting member 40. When the refrigerating member 38 is working, cold is generated on the side close to the heat conducting member 40. The cold is transferred to the magnetic attraction member 24 and the charging coil 18 through the heat conducting member 40 to reduce the temperature of the charging coil 18, and then the magnetic attraction member 24 and the charging coil 18 transfer the cold to the housing 12. And when the electronic device is in the charging process, it contacts the housing 12, so the cold can finally be transferred to the electronic device, thereby reducing the temperature of the electronic device to prolong the holding time of the fast charging mode of the electronic device.

[0051] In this embodiment, the refrigerating member 38 is a semiconductor refrigeration chip. During the working process, cold is generated on the side of the refrigerating member 38 close to the heat conducting member 40, and heat is generated on the side of the refrigerating member 38 away from the heat conducting member 40.

[0052] The cooling component 36 further includes a radiator 42 located inside the housing 12. The radiator 42 is thermally conductively connected to the side of the refrigerating member 38 away from the heat conducting member 40. The heat generated on the side of the refrigerating member 38 away from the heat conducting member 40 can be transferred to the radiator 42, and the radiator 42 dissipates the heat into the surrounding environment, which can reduce the temperature on the side of the refrigerating member 38 away from the heat conducting member 40 and ensure the refrigerating capacity of the refrigerating member 38.

[0053] Specifically, the radiator 42 is located on the side of the refrigerating member 38 away from the heat conducting member 40. The opposite sides of the refrigerating member 38 are respectively in contact with the heat conducting member 40 and the radiator 42 to form an effect of thermally conductive connection.

[0054] The specific type of the radiator 42 is not limited. In this embodiment, the radiator 42 is a finned radiator 42. A plurality of heat dissipation fins 44 are provided on the side of the radiator 42 away from the refrigerating member 38. The plurality of heat dissipation fins 44 are arranged in parallel at intervals to increase the surface area of the radiator 42 in contact with the air and improve the heat dissipation performance of the radiator 42.

[0055] The cooling component 36 further includes a mounting bracket 46 located inside the housing 12. The mounting bracket 46 is relatively fixed to the housing 12. The radiator 42 is fixed on the mounting bracket 46. A mounting position 48 is provided on the mounting bracket 46, and the refrigerating member 38 is arranged in the mounting position 48. After the cooling component 36 is assembled together, the refrigerating member 38 is limited by the radiator 42 and the heat conducting member 40 in the vertical direction, and is limited by the inner wall of the mounting position 48 in the horizontal direction, so that the refrigerating member 38 is kept in the corresponding position.

[0056] Specifically, the mounting position 48 penetrates through the mounting bracket 46, and the depth of the mounting position 48 is less than or equal to the thickness of the refrigerating member 38. The opposite sides of the refrigerating member 38 are respectively in contact with the heat conducting member 40 and the radiator 42 to improve the compactness of the overall structure of the cooling component 36. Preferably, in this embodiment, the depth of the mounting position 48 is the same as the thickness of the refrigerating member 38.

[0057] In one embodiment, the cooling component 36 further includes a blower 50 located inside the housing 12. The blower 50 is electrically connected to the circuit board 20 of the charging component 14. The housing 12 is provided with a receiving cavity 32, an air inlet 52 and an air outlet 54 that are respectively communicated with the receiving cavity 32. The charging component 14 and the cooling component 36 are respectively received in the receiving cavity 32. That is, components such as the blower 50, the refrigerating member 38, the heat conducting member 40, the radiator 42, the energy storage member 16, the circuit board 20, and the charging coil 18 are all located inside the receiving cavity 32. When the blower 50 operates, it can suck the outside air into the receiving cavity 32 through the air inlet 52 and flow toward the air outlet 54, and finally discharge from the air outlet 54. The heat in the receiving cavity 32 can be taken away during the air flow process, preventing the heat generated during the operation of the charging component 14 and the cooling component 36 from accumulating in the receiving cavity 32 and reducing the overall temperature inside the receiving cavity 32.

[0058] The specific type of the blower 50 is not limited. It can be a centrifugal blower 50 or an axial flow blower 50.

[0059] Specifically, the blower 50 is located on the side of the radiator 42 away from the refrigerating member 38. The circuit board 20 is installed on the mounting bracket 46 and is located on one side of the blower 50. When the blower 50 drives the air to flow from the air inlet 52 to the air outlet 54, the air will pass through the radiator 42 and the circuit board 20, thereby taking away the heat on the radiator 42 and the circuit board 20.

[0060] The air inlet 52 and the air outlet 54 are respectively located on opposite sides of the housing 12. The charging component 14 and the cooling component 36 are arranged in the direction from the air inlet 52 to the air outlet 54. Therefore, when the air flows from the air inlet 52 to the air outlet 54, it will pass through components such as the energy storage member 16, the charging coil 18, the circuit board 20, and the radiator 42, thereby taking away the heat on the corresponding components.

[0061] In this embodiment, the housing 12 is generally rectangular. The air inlet 52 and the air outlet 54 are provided on both sides of the housing 12 in the length direction, increasing the distance between the air inlet 52 and the air outlet 54, extending the air flow path, and enabling the air to pass through more components to improve the heat dissipation effect of the blower 50.

[0062] It can be understood that the arrangement of the charging component 14 and the cooling component 36 in the direction from the air inlet 52 to the air outlet 54 can mean that the charging component 14 is close to the air inlet 52 and the cooling component 36 is close to the air outlet 54, or it can mean that the charging component 14 is close to the air outlet 54 and the cooling component 36 is close to the air inlet 52. In this embodiment, the direction from the air inlet 52 to the air outlet 54 is also the length direction of the housing 12.

[0063] Please refer to Figure 8, in one embodiment, the charging coil 18 is at least partially located outside the outer contour track of the energy storage member 16, the cooling member 38 is located outside the outer contour track of the energy storage member 16, and the charging coil 18 and the cooling member 38 are close to the same end of the energy storage member 16. Specifically, the energy storage member 16 is close to the air inlet 52, the charging coil 18 is at least partially located outside the end of the energy storage member 16 away from the air inlet 52, and the cooling member 38 is located on the side of the energy storage member 16 away from the air inlet 52, that is, the charging coil 18 and the cooling member 38 are close to the air outlet 54. The cooling member 38 is located on the side of the charging coil 18 away from the panel 28. The charging coil 18, the heat conduction member 40, and the cooling member 38 form a stacked arrangement. At this time, the heat transfer path between the cooling member 38 and the charging coil 18 is short, and the size of the heat conduction member 40 is relatively small. When the fan 50 operates, air enters the accommodation cavity 32 from the air inlet 52, first passes through the energy storage member 16, then passes through the radiator 42, and finally exits from the air outlet 54.

[0064] Please refer to Figure 9 , in another embodiment, the charging coil 18 is located inside the outer contour track of the energy storage member 16, the cooling member 38 is located outside the outer contour track of the energy storage member 16, the charging coil 18 is close to one end of the energy storage member 16, the cooling member 38 is close to the other end of the energy storage member 16, and the heat conduction member 40 extends from the cooling member 38 to the charging coil 18. Specifically, the energy storage member 16 is close to the air outlet 54, and the charging coil 18 is entirely located inside the outer contour track of the energy storage member 16, that is, the charging coil 18 does not extend outside the periphery of the energy storage member 16. The charging coil 18 is located at one end of the energy storage member 16 close to the air outlet 54, the cooling member 38 is close to the air inlet 52, and the heat conduction member 40 extends along the direction from the air inlet 52 to the air outlet 54. At this time, the heat transfer path between the cooling member 38 and the charging coil 18 is long, and the size of the heat conduction member 40 is relatively large. When the fan 50 operates, air enters the accommodation cavity 32 from the air inlet 52, first passes through the radiator 42, then passes through the energy storage member 16, and finally exits from the air outlet 54.

[0065] In one embodiment, a bracket 56 is provided on the outer side of the housing 12, and the bracket 56 is rotatably connected to the housing 12. Specifically, the bracket 56 is rotatably connected to the back plate 30. When the bracket 56 rotates relative to the housing 12 by a certain angle, the bracket 56 can support the housing 12, and thus support the electronic device, so as to watch videos during the charging process.

[0066] Preferably, the bracket 56 is a metal part with good heat conduction ability. The energy storage member 16 is thermally connected to the back plate 30. Therefore, the heat generated by the energy storage member 16 can be transferred to the bracket 56 through the back plate 30, and the bracket 56 is used to assist the energy storage member 16 in heat dissipation.

[0067] A groove 58 is provided on the outer side of the back plate 30, and the bracket 56 is installed in the groove 58. When the bracket 56 is not in use, the bracket 56 can be rotated and stored in the groove 58, reducing the obtrusiveness of the bracket 56. At the same time, the distance between the energy storage member 16 and the bracket 56 can also be shortened, thereby reducing the heat transfer path between the energy storage member 16 and the bracket 56, enabling the heat on the energy storage member 16 to be transferred to the bracket 56 more quickly.

[0068] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention fall within the scope of protection required by the present invention.
