Description

Technical Field

[0001] The present invention relates to the field of power supply, and in particular to a power box shell and a portable energy storage power box. Background Art

[0002] Portable energy storage power supplies, also known as outdoor power supplies (Portable PowerStation), are commonly used for outdoor travel and earthquake and disaster relief. In both Europe and the United States, as well as in my country, demand for portable energy storage power supplies is surging among self-driving enthusiasts, RV tours, outdoor travel groups, and individual travelers. These products offer diverse functions, providing power and lighting for outdoor use, enriching outdoor life. In earthquake and disaster relief applications, they can address power outages, provide lighting, and provide emergency rescue services, making them particularly important during severe natural disasters like earthquakes and hurricanes. Furthermore, medical equipment power supplies and lithium battery generators are emerging as emerging applications for outdoor portable energy storage power supplies. Medical equipment power supplies, primarily for ventilators, are used in emergencies such as field and emergency medical services to mitigate power outages caused by a lack of utility power, thereby reducing the risk to personal safety. With the development of society, electricity has become indispensable in daily life and work, but it often presents challenges such as outdoor power supply, equipment backup power, and power outages. Power outages and power outages can disrupt work and disrupt people's daily lives. Power outages are commonplace, especially during the peak summer months. Remote areas often face power outages and power shortages, and portable, storable power supplies are a solution.

[0003] For portable energy storage power boxes with high capacitance, the shell of traditional power boxes is generally made of all-plastic material due to cost issues. The all-plastic material has poor structural strength. For high-capacity power boxes, the plastic handle is prone to breakage due to heavy weight. At the same time, the internal heat generation of high-capacity power boxes is high, and the heat dissipation effect of the plastic shell is poor, which can easily shorten the service life of the battery components due to poor heat dissipation.

[0034] The power box shell provided in the present application includes a plastic shell assembly, a metal heat sink and a metal handle assembly; the plastic shell assembly includes an upper shell and a lower shell bonded in sequence, and the upper shell and the lower shell are formed with multiple heat sink mounting positions; the number of the metal heat sink is at least one, and the metal heat sink is installed on the heat sink mounting position so that the metal heat sink is connected to the upper shell and the lower shell; the number of the metal handle assembly is at least one, and the metal handle assembly includes a mounting plate, a reinforcement plate and a handle piece, the mounting plate is installed on the surface of the upper shell, the reinforcement plate is installed on the back of the upper shell, and the handle piece is rotatably connected to the mounting plate.

[0035] See also Figures 1 to 7 In order to better understand the power box housing 10 of the present application, the power box housing 10 is further explained below:

[0036] A power box housing 10 in one embodiment includes a plastic shell assembly 100, a metal heat sink 200 and a metal handle assembly 300; the plastic shell assembly 100 includes an upper shell 110 and a lower shell 120 bonded in sequence, and the upper shell 110 and the lower shell 120 are formed with multiple heat sink mounting positions 102; the number of the metal heat sink 200 is at least one, and the metal heat sink 200 is installed on the heat sink mounting position 102 so that the metal heat sink 200 is connected to the upper shell 110 and the lower shell 120; the number of the metal handle assembly 300 is at least one, and the metal handle assembly 300 includes a mounting plate 310, a reinforcing plate 320 and a handle piece 330, the mounting plate 310 is installed on the surface of the upper shell 110, the reinforcing plate 320 is installed on the back of the upper shell 110, and the handle piece 330 is rotatably connected to the mounting plate 310. For portable energy storage power boxes with high capacitance, the traditional power box housing 10 is generally made of all-plastic material due to cost issues. The all-plastic material has poor structural strength. For power boxes with high capacitance, the plastic handle is prone to breakage due to heavy weight. At the same time, the internal heat generation of the high-capacity power box is high, and the heat dissipation effect of the plastic housing is poor, which can easily shorten the service life of the battery assembly due to poor heat dissipation. In this embodiment, a plastic shell assembly 100 is provided, a heat sink mounting position 102 is formed on the upper shell 110 and the lower shell 120, and a metal heat sink 200 is installed on the heat sink mounting position 102. The heat in the power box housing 10 is dissipated through the metal heat sink 200. Since metal is naturally better than plastic in heat dissipation effect, the metal heat sink 200 is provided in the heat dissipation area to make the metal and plastic integrated, which can effectively improve the heat dissipation effect of the battery box housing without increasing the cost too much. Furthermore, by providing a metal handle assembly 300, a mounting plate 310 and a reinforcing plate 320 are respectively provided on the surface and the back of the upper shell 110, that is, the load-bearing force of the handle member 330 is relieved by the reinforcing plate 320 when the handle member 330 bears weight. Because the structural strength of metal is higher than that of plastic, and the mounting plate 310 and the reinforcing plate 320 are made of metal, the overall structural strength is effectively guaranteed. Therefore, the handle member 330 is not prone to breakage, thereby effectively improving the structural strength of the metal handle assembly 300, and further effectively improving the structural strength of the power box housing 10.

[0037] like Figure 1 As shown, in one embodiment, the upper shell 110 and the lower shell 120 are integrally injection molded. It should be noted that the upper shell 110 and the lower shell 120 are integrally injection molded by a mold. Such a shell molding has good structural strength and structural stability, which can effectively improve the structural strength and structural stability of the power box shell 10 while saving production costs.

[0038] like Figure 1 and Figure 6 As shown, in one embodiment, the upper shell 110 and the lower shell 120 are formed with two heat sink mounting positions 102, and the two heat sink mounting positions 102 are distributed at both ends of the upper shell 110 and the lower shell 120; the number of the metal heat sinks 200 is two, and each of the metal heat sinks 200 is installed on one of the heat sink mounting positions 102, so that each of the metal heat sinks 200 is connected to the upper shell 110 and the lower shell 120. It should be noted that different numbers of heat sink mounting positions 102 and different numbers of metal heat sinks 200 can be set according to the length of the power supply box housing 10 and the size of the power supply assembly. In this embodiment, the upper shell 110 and the lower shell 120 are formed with two heat sink mounting positions 102, and the number of the metal heat sinks 200 is two. The two metal heat sinks 200 dissipate the heat in the power box housing 10 , which can greatly improve the heat dissipation effect of the power box housing 10 and avoid the situation where the service life of the power box is shortened due to poor heat dissipation effect of the power box housing 10 .

[0039] like Figure 1 、 Figure 6 and Figure 7 As shown, in one embodiment, the metal heat sink 200 is formed with a plurality of heat dissipation fan mounting positions 202 and a plurality of heat dissipation holes 204. Each of the heat dissipation fan mounting positions 202 is connected to a plurality of the heat dissipation holes 204. The heat dissipation holes 204 are used to dissipate the heat in the plastic shell assembly 100. Each heat dissipation fan is installed in a heat dissipation fan mounting position 202 to dissipate heat from the power supply assembly. It can be understood that by providing a heat dissipation fan and combining the good heat dissipation effect of metal, the heat dissipation effect of the power supply box housing 10 can be effectively improved compared to traditional plastic shells without increasing the cost too much. Furthermore, by providing a plurality of heat dissipation holes 204, heat can be effectively dissipated through the holes. Combined with the heat dissipation effect of the metal itself, the heat dissipation effect of the power supply box housing 10 can be greatly improved, thereby effectively avoiding the situation where the service life of the power supply assembly is shortened due to the poor heat dissipation effect of the power supply box housing 10.

[0040] like Figures 2 to 5As shown, in one embodiment, the number of the metal handle assemblies 300 is two, and the first metal handle assembly 300a and the second metal handle assembly 300b are evenly distributed at both ends of the upper shell 110. It should be noted that the handle assembly plays a load-bearing role, and the number of handle assemblies provided varies according to the size of the power box. In this embodiment, the number of the metal handle assemblies 300 is two, and the first metal handle assembly 300a and the second metal handle assembly 300b are evenly distributed at both ends of the upper shell 110, which can facilitate the user to lift the power box while ensuring that the power box housing 10 is evenly stressed. In this way, it is less likely that the handle member 330 will break, thereby effectively ensuring the structural strength and stability of the power box housing 10.

[0041] like Figures 2 to 4 As shown, in one embodiment, the first metal handle assembly 300a includes a first mounting plate 310a, a first reinforcement plate 320a and a first handle piece 330a, the first mounting plate 310a is mounted on one end of the surface of the upper shell 110, the first reinforcement plate 320a is mounted on one end of the back side of the upper shell 110, and the first handle piece 330a is rotatably connected to the first mounting plate 310a. It should be noted that a first mounting plate 310a and a first reinforcing plate 320a are respectively provided on the surface and the back of one end of the upper shell 110, that is, the first handle member 330a relieves the load-bearing force of the first handle member 330a through the first reinforcing plate 320a when bearing weight. Because the structural strength of metal is higher than that of plastic, and the first mounting plate 310a and the first reinforcing plate 320a made of metal are used at the same time, the overall structural strength is effectively guaranteed. Therefore, the first handle member 330a is not prone to breakage, thereby effectively improving the structural strength of the first metal handle assembly 300a, and then effectively improving the structural strength of the power box shell 10.

[0042] like Figures 2 to 4 As shown, in one embodiment, the first mounting plate 310a, the upper shell 110 and the first reinforcing plate 320a are riveted in sequence. It can be understood that the first mounting plate 310a, the upper shell 110 and the first reinforcing plate 320a are riveted together by rivets, which can ensure the stability of the connection between the first mounting plate 310a, the upper shell 110 and the first reinforcing plate 320a, that is, improve the connection strength between the first mounting plate 310a, the upper shell 110 and the first reinforcing plate 320a, thereby effectively improving the structural connection stability between the first metal handle assembly 300a and the upper shell 110, and further effectively improving the structural strength and structural stability of the power box housing 10.

[0043] like Figures 2 to 5As shown in one embodiment, the second metal handle assembly 300b includes a second mounting plate 310b, a second reinforcement plate 320b, and a second handle member 330b. The second mounting plate 310b is mounted on the other end of the surface of the upper housing 110, and the second reinforcement plate 320b is mounted on the other end of the back of the upper housing 110. The second handle member 330b is rotatably connected to the second mounting plate 310b. It should be noted that the second mounting plate 310b and the second reinforcement plate 320b are respectively provided on the surface and back of the other end of the upper housing 110. That is, when the second handle member 330b is bearing weight, the second reinforcement plate 320b relieves the load of the second handle member 330b. Because metal has a higher structural strength than plastic, the combination of the metal second mounting plate 310b and the metal reinforcement plate 320b effectively ensures the overall structural strength. Therefore, the second handle member 330b is less likely to break, thereby effectively improving the structural strength of the second metal handle assembly 300b and, in turn, the structural strength of the power box housing 10.

[0044] like Figures 2 to 5 As shown, in one embodiment, the second mounting plate 310b, the upper shell 110 and the second reinforcing plate 320b are riveted in sequence. It can be understood that the second mounting plate 310b, the upper shell 110 and the second reinforcing plate 320b are riveted together by rivets, which can ensure the stability of the connection between the second mounting plate 310b, the upper shell 110 and the second reinforcing plate 320b, that is, improve the connection strength between the second mounting plate 310b, the upper shell 110 and the second reinforcing plate 320b, thereby effectively improving the structural connection stability between the second metal handle assembly 300b and the upper shell 110, and further effectively improving the structural strength and structural stability of the power box housing 10.

[0045] Furthermore, if Figure 1As shown, in one embodiment, the upper shell 110 is formed with at least one handle storage groove 112, the metal handle assembly 300 is arranged in the handle storage groove 112, the mounting plate 310 is installed on the inner wall of the handle storage groove 112 so that the mounting plate 310 is connected to the upper shell 110, the reinforcing plate 320 is installed on the side of the upper shell 110 away from the mounting plate 310, and the handle member 330 is rotatably connected to the mounting plate 310 so that the handle member 330 is stored in the handle storage groove 112. It should be noted that the handle storage slot 112 serves to store the handle member 330, that is, when not in use, the handle member 330 can be stored in the handle storage slot 112 for storage and protection, effectively preventing the handle member 330 from being bumped and worn during transportation, and at the same time will not affect the flatness of the upper shell 110, effectively improving the flatness of the power box casing 10.

[0046] Furthermore, in one embodiment, the handle is provided with the aforementioned thermal insulation layer. It is understandable that, because metal naturally has better thermal conductivity than plastic, the handle is required to move the power supply box while it is in use. However, the handle generates a high temperature during this process, which can easily cause burns to the user. Therefore, providing the handle with a thermal insulation layer can effectively prevent burns to the user due to the high temperature of the handle, thereby effectively improving the safety of the power supply box housing.

[0047] Furthermore, the power supply box housing also includes a metal support heat conductive strip, which is connected to the mounting plate and the reinforcement plate respectively. The upper shell is formed with a position-avoiding support groove. The metal support heat conductive strip is located in the position-avoiding support groove and is fixedly connected to the upper shell, which not only improves the heat dissipation performance of the power supply box housing, but also improves the structural strength of the power supply box housing. Furthermore, the metal support heat conductive strip is welded and fixed to the upper shell, so that the metal support heat conductive strip is firmly connected to the upper shell, while improving the structural strength of the power supply box housing, and allowing the heat of the housing to be quickly conducted to the mounting plate or the reinforcement plate for heat dissipation, and the heat of the mounting plate and the heat of the reinforcement plate can be balanced and dissipated at any point, avoiding local overheating, and improving the heat dissipation performance of the power supply box housing. Furthermore, the metal support heat conductive strip is welded to the mounting plate and the reinforcement plate respectively, effectively improving the connection strength between the mounting plate, the reinforcement plate and the upper shell, thereby effectively improving the structural strength of the power supply box housing. Furthermore, the two ends of the metal support thermal conductive strip extend to the edges of the mounting plate and the reinforcing plate respectively, which can further improve the connection strength between the mounting plate, the reinforcing plate and the upper shell, while also improving the heat dissipation effect of the upper shell, thereby effectively improving the structural strength and heat dissipation effect of the power box casing.

[0048] Furthermore, there are two metal support thermal conductive strips, namely a first metal support thermal conductive strip and a second metal support thermal conductive strip. The first metal support thermal conductive strip is welded to the first mounting plate and the first reinforcing plate respectively, and the second metal support thermal conductive strip is welded to the second mounting plate and the second reinforcing plate respectively.

[0049] Furthermore, the power supply box housing includes intermediate support heat dissipation columns, which are connected to the first metal support heat conductive strip and the second metal heat conductive strip, respectively. The intermediate support heat dissipation columns effectively enhance the overall heat dissipation of the upper housing and strengthen the connection between the upper housing and the two metal handles, thereby effectively improving the heat dissipation and structural strength of the power supply box housing.

[0050] Furthermore, the upper shell is provided with multiple ventilation and heat dissipation holes near the middle support heat dissipation column. By providing multiple ventilation and heat dissipation holes, the upper shell has better heat dissipation performance. Combined with the multiple heat dissipation holes in the two metal heat dissipation plates to form a U-shaped heat dissipation outlet, it can greatly improve the heat dissipation effect of the power box shell.

[0051] The present application also provides a portable energy storage power box, comprising a power supply assembly, multiple cooling fans and the power box housing described in any one of the above embodiments, the multiple cooling fans are electrically connected to the power supply assembly, the upper shell and the lower shell also form a accommodating area, the power supply assembly is arranged in the accommodating area, the accommodating area is connected to the multiple heat sink mounting positions, and each of the cooling fans is installed on a heat sink mounting position.

[0052] In this embodiment, a plastic housing assembly is provided, heat sink mounting positions are formed on the upper and lower housings, a metal heat sink is mounted on the heat sink mounting position, and a heat dissipation fan is mounted on the heat dissipation fan mounting position. The heat within the power supply box housing is dissipated through the heat dissipation fan and the metal heat sink. Since metal is naturally better than plastic in heat dissipation, a metal heat sink is provided in the heat dissipation area, integrating metal and plastic. This effectively improves the heat dissipation effect of the battery box housing without increasing costs excessively. The combined use of the heat dissipation fan and the metal heat sink effectively dissipates the heat generated by the power supply components within the portable energy storage power supply box, thereby effectively avoiding a shortened service life of the power supply components due to poor heat dissipation of the power supply box housing, thereby effectively improving the heat dissipation effect and service life of the portable energy storage power supply box. Furthermore, by providing a metal handle assembly, a mounting plate and a reinforcement plate are respectively provided on the surface and back of the upper shell, that is, the load-bearing force of the handle is relieved by the reinforcement plate when the handle bears weight. Because the structural strength of metal is higher than that of plastic, and the mounting plate and reinforcement plate are made of metal, the overall structural strength is effectively guaranteed. Therefore, the handle is not prone to breakage, thereby effectively improving the structural strength of the metal handle assembly, and then effectively improving the structural strength of the power box shell.

[0053] Furthermore, in one embodiment, a temperature sensor is provided within the plastic housing assembly, electrically connected to the power supply assembly and the plurality of cooling fans. It is understood that the temperature sensor monitors temperature changes within the plastic housing assembly and adjusts the speed of the plurality of cooling fans accordingly based on the temperature change signal within the plastic housing assembly. This not only effectively solves the heat dissipation problem of the portable energy storage power supply box but also maximizes the utilization of the cooling fans, thereby ensuring effective heat dissipation while saving energy.

[0054] Furthermore, in one embodiment, an alarm is provided within the plastic housing assembly, and the alarm is electrically connected to the power supply assembly and the temperature sensor, respectively. It is understood that when the temperature within the plastic housing assembly exceeds a preset value of the temperature sensor, the temperature sensor outputs an electrical signal to the alarm, which then generates an alarm signal to alert the user that the power supply assembly is generating excessive heat, prompting the user to promptly stop using the portable energy storage power supply box, thereby avoiding shortening the service life of the power supply assembly due to excessive heat generation, thereby effectively extending the service life of the portable energy storage power supply box.

[0055] Compared with the prior art, the present invention has at least the following advantages:

[0056] 1. The power box housing of the present invention is provided with a plastic shell assembly, and heat sink mounting positions are formed on the upper shell and the lower shell. A metal heat sink is then installed on the heat sink mounting positions. The heat in the power box housing is dissipated through the metal heat sink. Since metal is naturally better than plastic in heat dissipation effect, a metal heat sink is provided in the heat dissipation area to integrate metal and plastic, which can effectively improve the heat dissipation effect of the battery box housing without increasing the cost too much.

[0057] 2. The power box shell of the present invention is provided with a metal handle assembly, and a mounting plate and a reinforcing plate are respectively provided on the surface and back of the upper shell. That is, the reinforcing plate relieves the load-bearing force of the handle when the handle bears weight. Because the structural strength of metal is higher than that of plastic, and the mounting plate and reinforcing plate are made of metal, the overall structural strength is effectively guaranteed. Therefore, the handle is not prone to breakage, thereby effectively improving the structural strength of the metal handle assembly, and then effectively improving the structural strength of the power box shell.

[0058] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
