Abstract
Description
Technical Field
[0001] This application relates to the field of charging equipment technology, and more specifically, to a temperature-controlled power bank. Background Technology
[0002] With the widespread use of mobile electronic devices, power banks, as portable power devices that can charge mobile electronic devices anytime, anywhere, have greatly facilitated people's lives. Currently, most power banks on the market mainly consist of a battery cell and a casing, with the battery cell housed within the casing. The battery cell is the key component for storing electrical energy, and it generates a significant amount of heat during charging and discharging.
[0003] However, traditional power banks mainly dissipate the heat generated by the battery cells to the surrounding environment through the outer casing. The heat dissipation rate of the casing is limited. When the battery cells generate a lot of heat, the casing cannot dissipate the heat in time, which leads to the temperature of the casing rising. When users hold a working power bank, they often feel that it is too hot to touch, causing discomfort to their hands and resulting in a poor user experience. Utility Model Content

[0039] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.
[0040] like Figure 1and Figure 2 As shown, one embodiment of this application provides a temperature-controlled power bank, including a housing 100, a charging / discharging assembly 200, and a heat sink 300. The housing 100 includes a frame 110 and two substrates 120. The two substrates 120 respectively cover opposite sides of the frame 110 in a first direction. The frame 110 and the two substrates 120 enclose an inner cavity. The frame 110 has at least one heat dissipation hole 114, which communicates with the inner cavity and the outside. The charging / discharging assembly 200 is disposed in the inner cavity. The heat sink 300 is disposed between the charging / discharging assembly 200 and one of the substrates 120, with each heat dissipation hole 114 facing the heat sink 300 in a direction perpendicular to the first direction.
[0041] In the embodiments of this application, the frame 110 and the two substrates 120 may be made of plastic, metal or other suitable materials, and no unique limitation is made here.
[0042] The temperature-controlled power bank of this application embodiment, by setting a heat sink 300 between the charging / discharging component 200 and one of the substrates 120, and opening heat dissipation holes 114 on the frame 110 opposite to the heat sink 300, allows the heat generated by the charging / discharging component 200 during operation to be preferentially absorbed by the heat sink 300. The heat dissipation holes 114 facilitate faster airflow between the inner cavity and the external environment, enabling the heat from the heat sink 300 to be quickly dissipated to the outside, forming an efficient internal and external heat circulation, effectively improving the heat dissipation rate. In addition, since the heat generated by the charging / discharging component 200 can be preferentially carried away by the heat sink 300, the heat absorbed by the casing 100 is effectively reduced, thereby lowering the temperature of the casing 100 and improving the user experience.
[0043] In this embodiment, the heat sink 300 has a structure with strong thermal conductivity. In an optional embodiment, such as Figure 3 As shown, the radiator 300 includes a heat sink 310 and multiple heat sink fins 320. The multiple heat sink fins 320 are spaced apart on one side of the heat sink 310, and the other side of the heat sink 310 is connected to the charging and discharging assembly 200. The heat sink 310 absorbs the heat generated by the charging and discharging assembly 200. By providing multiple heat sink fins 320, the contact area between the radiator 300 and the air is increased, so that the heat in the radiator 300 can be quickly removed by airflow, thereby improving the heat dissipation efficiency.
[0044] Optionally, the heat sink fins 320 and the heat sink 310 can be connected by welding, gluing, or integral molding. Optionally, the heat sink 310 and the charging / discharging assembly 200 can be connected by gluing, snap-fitting, or other suitable methods, without limitation.
[0045] In one possible design, such as Figure 3 and Figure 4 As shown, the frame 110 includes two first sidewalls 111 spaced apart along a second direction, which forms an angle with the first direction. Each first sidewall 111 has at least one heat dissipation hole 114 extending through it, and each heat dissipation fin 320 is arranged parallel to the second direction. In this arrangement, the air in the cavity mainly flows from near one of the first sidewalls 111 to near the other, meaning the airflow direction is generally parallel to the second direction. Therefore, arranging the heat dissipation fins 320 parallel to the second direction reduces the resistance to airflow, facilitating rapid airflow and improving heat dissipation efficiency.
[0046] Optionally, the first direction and the second direction can be set at various different angles. For example, the first direction and the second direction can be set perpendicularly. For ease of description, the following explanation will use the example of the first direction and the second direction being perpendicular.
[0047] In some embodiments, each first sidewall 111 is provided with multiple sets of heat dissipation holes 114, each set including at least one heat dissipation hole 114. The multiple sets of heat dissipation holes 114 on the first sidewall 111 are spaced apart along a third direction, and the third direction is set at an angle to the first direction and the second direction, respectively. In this embodiment, when each set of heat dissipation holes 114 includes multiple heat dissipation holes 114, the multiple heat dissipation holes 114 in each set can be spaced apart along the first direction. Optionally, the multiple heat dissipation fins 320 on the heat sink 310 are spaced apart along a third direction.
[0048] Optionally, the angle between the third direction and the first and second directions can be 60 degrees, 73 degrees, 75 degrees, or 90 degrees, respectively. In one example, the first direction, the second direction, and the third direction are arranged perpendicularly to each other. In the figures provided in the embodiments of this application, the first direction is indicated by a double arrow AA, the second direction by a double arrow BB, and the third direction by a double arrow CC.
[0049] In one possible design, such as Figure 3 and Figure 4As shown, the frame 110 also includes two second sidewalls 112 spaced apart along a third direction, each second sidewall 112 having at least one heat dissipation hole 114 through it. The plurality of heat dissipation fins 320 are divided into at least two groups, each group including at least one heat dissipation fin 320, and the at least two groups of heat dissipation fins 320 are spaced apart along a second direction. This arrangement allows ventilation on all four sides of the frame 110, which is more conducive to dissipating heat from the inner cavity to the outside, further improving heat dissipation efficiency. Spaced apart at least two groups of heat dissipation fins 320 along the second direction reduces the resistance encountered when air flows from near one of the second sidewalls 112 to near the other, which helps to accelerate the airflow speed within the inner cavity.
[0050] In one specific embodiment, a plurality of heat dissipation fins 320 are arranged in a rectangular array on the heat dissipation plate 310. Specifically, the plurality of heat dissipation fins 320 are divided into multiple groups, and the multiple groups of heat dissipation fins 320 are spaced apart along a second direction. Each group of heat dissipation fins 320 includes a plurality of heat dissipation fins 320, and the plurality of heat dissipation fins 320 in each group of heat dissipation fins 320 are spaced apart along a third direction.
[0051] In one possible design, such as Figure 2 As shown, the charging and discharging assembly 200 includes a battery cell 210, a magnetic attraction part 230, and a wireless charging coil 220. The magnetic attraction part 230 and the wireless charging coil 220 are mounted on one side of the battery cell 210 in a first direction, and the magnetic attraction part 230 surrounds the outer periphery of the wireless charging coil 220. The battery cell 210 is used to store and release electrical energy, the magnetic attraction part 230 is used to attract external electronic devices, and the wireless charging coil 220 is used to wirelessly transmit the electrical energy in the battery cell 210 to the external electronic devices. Thus, the temperature-controlled power bank provided in this embodiment of the application has a wireless magnetic charging function.
[0052] In this embodiment, a circuit board 400 is also provided in the inner cavity, and the wireless charging coil 220 and the battery cell 210 are electrically connected to the circuit board 400. Optionally, a charging interface 410 is also provided on one side wall (first side wall 111 or second side wall 112) of the frame 110. The charging interface 410 is electrically connected to the circuit board 400, and external electronic devices can also be charged through the charging interface 410. Optionally, the battery cell 210 can also be charged through the charging interface 410.
[0053] In one possible design, such as Figure 2As shown, the magnetic suction part 230 and the wireless charging coil 220 are located on the first side of the battery cell 210 in the first direction, and the heat sink 300 is located on the second side of the battery cell 210 in the first direction, with the first and second sides facing away from each other. This arrangement allows the magnetic suction part 230 to be positioned close to one of the substrates 120, enabling it to more stably attract external electronic devices and improve the reliability of the temperature-controlled power bank. In addition, it allows the heat sink 300 to be positioned between the battery cell 210 and the other substrate 120, allowing it to absorb the heat generated by the battery cell 210 more quickly.
[0054] In one possible design, such as Figure 1 , Figure 2 and Figure 4 As shown, a recess 127 is formed on the side of the substrate 120 located on the first side of the battery cell 210 in the first direction, away from the battery cell 210. The recess 127 is opposite to the center of the wireless charging coil 220 in the first direction. By providing the recess 127, the user can quickly determine the position of the magnetic part 230 and the wireless charging coil 220, thus improving the ease of use of the temperature-controlled power bank.
[0055] In one possible design, such as Figure 2 and Figure 4 As shown, a reinforcing rib is formed on the side of the substrate 120 on the first side of the battery cell 210 in the first direction facing the battery cell 210. The reinforcing rib and the substrate 120 on the first side of the battery cell 210 in the first direction surround and form a first receiving area 125 and a second receiving area 126. At least a portion of the structure of the magnetic suction part 230 is located in the first receiving area 125, and at least a portion of the structure of the wireless charging coil 220 is located in the second receiving area 126.
[0056] According to the above configuration, on the one hand, by setting reinforcing ribs, the structural strength of the substrate 120 with reinforcing ribs can be strengthened; on the other hand, by forming a first receiving area 125 for accommodating the magnetic part 230 and a second receiving area 126 for accommodating the wireless charging coil 220 by the reinforcing ribs and the substrate 120, the structure of the temperature-controlled power bank is more compact, and it is also beneficial to improve the installation stability of the magnetic part 230 and the wireless charging coil 220.
[0057] For example, the reinforcing rib includes a plurality of transverse plates 122, a plurality of longitudinal plates 123, and two annular plates 124, wherein the inner diameter of one annular plate 124 is larger than the outer diameter of the other annular plate 124, the annular plate 124 with the larger inner diameter surrounds the outer periphery of the annular plate 124 with the smaller outer diameter to form a first receiving area 125 between the two annular plates 124, and the annular plate 124 with the smaller outer diameter surrounds a second receiving area 126. The plurality of transverse plates 122 are all parallel to the second direction and spaced apart along the third direction, the plurality of longitudinal plates 123 are all parallel to the third direction and spaced apart along the second direction, and the plurality of transverse plates 122 and the plurality of longitudinal plates 123 are intersectingly arranged on the outer periphery of the annular plate 124 with the larger inner diameter.
[0058] Optionally, the two annular plates 124 can be fully enclosed annular structures or semi-enclosed annular structures, without being limited to one type.
[0059] Optionally, the substrate 120 located on the second side of the cell 210 in the first direction may also have reinforcing ribs on the side facing the cell 210.
[0060] In one possible design, the substrate 120 located on the first side of the battery cell 210 in the first direction is integrally formed with the frame 110, while the substrate 120 located on the second side of the battery cell 210 in the first direction is separately connected to the frame 110. This arrangement provides better protection for the magnetic part 230 and the wireless charging coil 220, and helps improve the reliability of temperature-controlled charging. Furthermore, by separately connecting the substrate 120 located on the second side of the battery cell 210 in the first direction to the frame 110, the substrate 120 on the second side of the battery cell 210 in the first direction can be detached, facilitating periodic cleaning or replacement of the heat sink 300.
[0061] In one possible design, such as Figures 4 to 7 As shown, a groove 113 is formed on the second side of the frame 110 in the first direction, and a protrusion 121 is formed on the side of the substrate 120 on the second side of the cell 210 in the first direction facing the frame 110. The protrusion 121 is inserted into the groove 113.
[0062] Optionally, the substrate 120 on the second side in the first direction and the frame 110 can be connected by an interference fit between the protrusion 121 and the groove 113. Alternatively, one of the outer surface of the protrusion 121 and the inner wall of the groove 113 is provided with a buckle, and the other is provided with a slot. When the protrusion 121 is inserted into the groove 113, the buckle is engaged in the slot, so as to realize the detachable connection between the substrate 120 on the second side in the first direction and the frame 110.
[0063] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
