As people's pace of life accelerates, various types of power tools (such as automated home equipment, DIY tools, etc.) are becoming more and more popular around the world, and commercial garden tools are one of them.

Commercial garden tools are professional power tools designed for garden workers or garden companies. They are generally called garden landscape maintenance equipment. They usually work on lawns, hedges, flowers, trees or gardens, etc., and can include the following tools. One or more of: lawn mowers, lawn mowers, pruners, chain saws, blowers, leaf shredders, snow blowers, etc.

The working power of commercial garden tools is generally high. For example, the power of a garden hair dryer is usually 2300W, and the power of a lawn mower is usually 2600W. Therefore, using fuel as a power source can well meet the working needs of commercial garden tools. And it can support commercial garden tools for long-term work. However, the use of fuel tools will cause environmental pollution, and the noise of fuel tools is loud, which is not good for the health of users. Therefore, people are always looking for alternatives to fuel powered tools.

Electricity is an environmentally friendly, clean, and renewable energy source, and power tools using it as a power source are becoming more and more popular. Under normal circumstances, power tools can be powered by either DC power or AC power, but the work of commercial garden tools is usually carried out outdoors. AC power is difficult to obtain. Therefore, in the field of commercial garden tools, it is more appropriate to use DC power supply. Preferably, the DC power supply can be a battery pack, which is convenient for the work team to carry with them when they go out.

The working scenario of commercial garden tools can be roughly described as follows: When the work team goes out to work during the day, they use vehicles to carry various garden tools needed for work to various gardens, such as push lawn mowers, smart lawn mowers and other wheeled lawn mowers. Power tools, as well as handheld power tools such as lawn mowers, pruners, and hair dryers; at the same time, the work team also needs to carry DC power sources, such as battery packs.

When working, the work team first came to the first garden and worked with various garden power tools they carried. When it comes to gardening, mowing usually takes the longest, and while the size of lawns varies from household to household, the average lawn mowing time is between 20 and 40 minutes. Therefore, at every garden, a worker immediately starts cutting the grass with a lawnmower. During the mowing period, another worker will use hand-held power tools to complete other types of work in sequence. For example, another worker will cut the grass first, then prune the branches, and then blow the grass. The two workers complete all the work almost at the same time, and then the work team Then transfer to the second garden. This cycle continues until the day's work is completed.

It can be seen that commercial garden tools have a heavy workload and long working hours; if you want to use electric tools to replace fuel tools, you must consider the continuous energy supply of electric tools.

One solution is to prepare a large number of battery packs to power power tools, which undoubtedly brings inconvenience and high work cost to the outgoing team who already carry many different garden tools; another solution is to use outdoor The energy storage power supply charges the battery pack directly on site.

The energy storage power supply usually includes a charging cabinet. When using the existing energy storage power supply to charge the battery pack, a large amount of heat will be generated. The generation of heat will cause the temperature of the charging cabinet to rise higher and activate the temperature protection function to stop the charging cabinet. work, which in turn reduces the charging time and easily reduces the life of the charging cabinet. In order to dissipate heat, vents are provided on the casing of the charging cabinet. However, opening cooling vents on the casing will result in a low protection level of the charging cabinet. When working in harsh environments, external dust, rainwater, etc. will enter.

In this way, the dustproof and waterproof level of the first electrical module 60 is at least IP67. Therefore, the technical solution provided by this application not only allows the first electrical module 60 that generates a large amount of heat to dissipate heat, but also adopts the method of separately packaging the first electrical module 60 to improve its protection level, making it suitable for various harsh environments. environment.

Specifically, in this embodiment, the charging cabinet 1 also includes a packaging box 64. Each packaging box 64 correspondingly packages a power component and a first control unit. The power components can be protected through the packaging of the packaging box 64 to avoid The power components are damaged.

Continuing to refer to FIGS. 6 and 7 , since the second control unit 71 and the switch module 72 in the second electrical module 70 need to be electrically connected to each power component in the first chamber B, the battery pack 400 is connected to the charging interface. At 30 o'clock, the second control unit 71 can control the relay to close, so that the electric energy received by the input interface 20 can be transmitted to the power components, and the power components are converted into the required current and voltage forms and then output from the charging interface 30 to the battery pack 400 .

In order to make the components in the first chamber B and the second chamber C electrically connected.

On the one hand, this simplifies the structure of the housing, and on the other hand, it also saves space. Optionally, the partition 104 is made of a metal material with higher structural strength.

Furthermore, in this embodiment, since a large amount of heat is generated during the operation of the first electrical module 60 and the charging process of the battery pack 400, the temperature inside the battery pack 400 and the charging cabinet 1 is excessively high. If the temperature inside the battery pack 400 and the charging cabinet 1 is too high, the battery pack 400 and the charging cabinet 1 will not work properly and their performance will be reduced. Therefore, heat dissipation of the battery pack 400 and the charging cabinet 1 is necessary. To this end, this application provides the following heat dissipation system, which will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 6 , in order to dissipate heat from the first electrical module 60 , a first type fan 90 is installed outside at least one packaging box 64 for heat dissipation. That is, the first type fan 90 is located in front of the first electrical module 60 . When the first type fan 90 is working, it can suck the gas in the first chamber B to the vicinity of the first electrical module 60. Specifically, when the first type fan 90 is working, it can suck the gas in the first chamber B to the vicinity of the first electrical module 60. The surface of the packaging box 64 is used to cool down the power components. In addition, in this embodiment, in order to improve the cooling effect, at least a plurality of heat dissipation fins 641 are provided on the surface of the packaging box 64 on which the first type fan 90 is installed, and each heat dissipation fin 641 extends along the up and down direction of the charging cabinet 1 , the gas sucked in by the first type fan 90 from the first chamber B blows onto the surface of the packaging box 64 and then flows along the extending direction of the heat dissipation fins 641 to dissipate heat to the packaging box 64 . In addition, in order to further improve the heat dissipation efficiency, the packaging box 64 and the heat dissipation fins 641 are preferably made of metal aluminum with better thermal conductivity.

In this embodiment, a first-type fan 90 is installed on each packaging box 64 . In an optional embodiment, more than two first-type fans 90 may be installed on each packaging box 64 , or some of the first-type fans 90 may not be installed on some packaging boxes 64 . The number, installation method and location of the first type of fans 90 are not specifically limited here and are subject to actual conditions. In addition, in this embodiment, the first type fan 90 is an axial flow fan. In an optional embodiment, the first type fan 90 may also be a centrifugal fan.

Further, in this embodiment, the first control unit contained in each packaging box 64 is electrically connected to the first type fan 90 fixed on the packaging box 64 to control the first type fan 90 electrically connected thereto. control.

In addition, in this embodiment, a first temperature sensor is installed in each packaging box 64. The first temperature sensor is used to detect the temperature in the packaging box 64 and transmit it to the first control unit. When the temperature in the packaging box 64 is greater than When equal to the first threshold, the first board is controlled to control the first type fan 90 electrically connected thereto to operate to draw the gas in the first chamber B toward the packaging box 64 to thereby dissipate heat from the power components. When the temperature inside the packaging box 64 is less than the first threshold, the first control unit controls the first type fan 90 electrically connected thereto to close and keep it until the temperature inside the packaging box 64 is greater than or equal to the first threshold, and then controls the first type fan 90 90 jobs. In this embodiment, when the temperature of the packaging box 64 is low, the first type fan 90 is not turned on to save energy consumption. When the temperature of the packaging box 64 is too high, the first type fan 90 is turned on to clean the power components. Heat dissipation, which not only saves energy consumption but also effectively dissipates heat for power components. Furthermore, in this embodiment, the first threshold is 50°C. In other embodiments, the first threshold may also be 45°C, 40°C, etc. The size of the first threshold is not specifically limited here and shall be subject to the actual situation.

In addition, in an optional embodiment, it can also be configured so that when the power components start charging, the first control unit simultaneously controls the first type fan 90 to work, so that the packaging box 64 is dissipated immediately after the power components start working. , to improve the heat dissipation effect and keep the temperature of the power components at a low level.

Further, as shown in FIGS. 4 , 5 and 7 , a large amount of heat will be generated during charging of the battery pack 400 , so heat dissipation of the battery pack 400 is also essential. To this end, in this embodiment, a second type fan 90 is provided near the charging interface 30 , and the second type fan 90 is configured to dissipate heat from the battery pack 400 . In this embodiment, the vent includes an air inlet and an air outlet 109 , and the air inlet includes a first air inlet 107 . Among them, the first air inlet 107 is connected to the gas outlet of the battery pack 400, and the charging cabinet 1 also includes a second type fan 90. The second type fan 90 is disposed near the first air inlet 107. The second type fan 90 is configured as Inhale the gas flowing through the external charging component into the first chamber Room B.

Specifically, in this embodiment, the third type fan 100 is installed on the first door body 102 and located behind the first air inlet 107 . When the battery pack 400 is connected to the charging interface 30 and charging, the first air inlet 107 is connected to the gas outlet of the battery pack 400; the second type fan 100 is configured to suck external air into the battery pack 400, and then through the gas outlet and the third An air inlet 107 draws in the first chamber B. Each first air inlet 107 may be provided with a second type of fan 100 , or only some of the first air inlets 107 may be provided with a second type of fan 100 . The details depend on the actual situation and are not specifically limited here.

In addition, as shown in FIG. 4 , the first air inlet 107 is disposed close to the charging interface 30 and located above the charging interface 30 . It can be understood that the first air inlet 107 can also be provided at other positions, as long as the first air inlet 107 can be connected with the gas outlet 403 of the battery pack 400 when the battery pack 400 is docked with the charging interface 30 .

In this embodiment, the first air inlet 107 provided on the first door body 101 is correspondingly provided with the second type fan 100, and the first air inlet 107 provided on the side wall 1011 of the housing body 101 is not provided with a corresponding second type fan. Class fan 100. The reason is that the internal space of the charging cabinet 1 of this embodiment is limited, and because the first air inlet 107 provided on the side wall 1011 of the housing body 101 corresponds to the second type battery pack 402, and the second type battery pack 402 The capacity is small, so when the second type battery pack 402 is charged, the heat generated in the second type battery pack 402 is small, and no additional second type fan 100 is needed to meet the heat dissipation requirements. In addition, in this embodiment, one second type fan 100 is provided corresponding to one first air inlet 107. In an optional embodiment, the number of second type fans 100 provided corresponding to one first air inlet 107 can also be It is more than two, and there is no specific limit here, and it shall be subject to actual needs.

Furthermore, since the gas used to dissipate heat from the battery pack 400 is a hot air flow, the hot air flow flowing into the first chamber B and then flowing toward the power components will result in poor heat dissipation effect of the power components. To this end, in an optional embodiment, partitions or pipes may also be provided in the first chamber B to dissipate the heat of the battery pack 400 and then flow into the first chamber B and dissipate the heat of the power components. The airflow is isolated to prevent hot airflow from flowing to the power components and causing poor heat dissipation of the power components. In addition, the air flow after dissipating heat from the battery pack 400 can be discharged from the housing 10 through the air outlet 109 provided on the housing 10 , or a separate air outlet can be provided to discharge the housing 10 , which is not specifically limited here.

In the above embodiment, the second type fan 100 is installed in the first chamber B. In an optional embodiment, the second type fan 100 can also be installed outside the housing 1 and near the charging interface 30. When the battery pack 400 is connected to the charging interface 30 , the second type fan 100 is connected to the gas outlet of the battery pack 400 to directly discharge the air flow that flows through the battery pack 400 to dissipate the heat of the battery pack 400 from the battery pack 400 without It is sucked into the first chamber B to further avoid the impact on the heat dissipation of the power components.

In this embodiment, due to the large internal wind resistance of the external charging component, such as the battery pack 400, in order to ensure a good heat dissipation effect, the second type of fan 100 is provided to suck more external air into the interior of the external charging component, and then through The first air inlet 107 sucks into the first chamber B, so the second type fan 100 is configured as a centrifugal fan capable of pressurizing gas. Of course, the second type of fan 100 does not exclude the use of other fans, such as axial flow fans.

Furthermore, in this embodiment, the second type fan 100 is electrically connected to the second control unit 71 , and the second type fan 100 is controlled through the second control unit 71 . In addition, a second temperature sensor is provided in the battery pack 400. When the second temperature sensor detects that the temperature in the battery pack 400 is greater than or equal to the second preset threshold, the second control unit 71 controls the second type fan 100 to operate to cool the battery. The gas in the battery pack 400 is drawn into the first chamber B from the second air inlet 108. When the temperature sensor detects that the temperature in the battery pack 400 is less than the second preset threshold, the second control unit 71 controls the second type fan 100 It is turned off until the temperature inside the battery pack 400 is greater than or equal to the second preset threshold, and then the second type fan 100 is controlled to operate to dissipate heat to the battery pack 400 . Alternatively, if the second temperature sensor detects that the temperature inside the battery pack 400 is always less than the second preset threshold, the second control unit 71 controls the second type fan 100 to always be in a closed state.

In this embodiment, when the temperature inside the battery pack 400 is low, the second type fan 100 is turned off to save energy consumption. When the temperature is too high, the second type fan 100 is operated to draw out the hot air in the battery pack 400, thereby lowering the temperature of the battery pack 400. This not only saves energy consumption but also effectively dissipates heat from the battery pack 400. Furthermore, in this embodiment, the second threshold is 35°C. In other embodiments, the second threshold may also be 30°C, 40°C, etc. The size of the second threshold is not specifically limited here and shall be subject to the actual situation.

In an optional embodiment, the second type of fan 100 can also be set to be turned on when the battery pack 400 starts to charge. In this way, the battery pack 400 is dissipated after the battery pack 400 starts to be charged, so as to improve the heat dissipation of the battery pack 400. As a result, the temperature inside the battery pack 400 is always kept at a lower level.

In addition, in this embodiment, since the power components generate a large amount of heat in the first chamber B after dissipating heat, it is difficult to quickly reduce the heat in the first chamber B through natural heat dissipation. Therefore, continuing to refer to Figures 6 and 7, in this embodiment, the vent also includes a second air inlet 108. External air can enter the first chamber B through the second air inlet 108, and the external air can enter the first chamber B from the second air inlet 108. When the air inlet 108 enters the first chamber B, the air pressure in the first chamber B will continue to rise, which is not conducive to the operation of the electronic device. In order to efficiently discharge the gas to the outside of the first chamber B, the charging cabinet 1 of this embodiment also includes a third type fan 110. The third type fan 110 is disposed close to the air outlet 109, and the air outlet side faces the air outlet 109. , is configured to suck the gas in the first chamber B to the vicinity of the air outlet 109, so that the gas is discharged from the air outlet 109, so as to realize the active exhaust of the gas in the first chamber B by the air outlet 109.

Further, in this embodiment, the third type of fan 110 is also configured to draw external air into the first chamber B through the first air inlet 107 and/or the second air inlet 108 to achieve ventilation of the first chamber B. B rapid ventilation to achieve the purpose of rapid cooling. That is, the third type fan 110 is configured to suck the external air into the first chamber B through the first air inlet 107 and/or the second air inlet 108, and then suck the outside air to the vicinity of the air outlet 109 after flowing through the first electrical module 60. And flows out of the first chamber B through the air outlet 109. The air outlet side of the third type fan 110 faces the air outlet 109, and the air inlet side faces the first chamber B.

In the technical solution provided by this application, when the charging cabinet 1 charges the battery pack 400 or the energy storage device 2, it can not only dissipate heat to the power components located in the first chamber B through the first type fan 90, but also use the first type fan 90 to dissipate heat. The second type fan 100 dissipates heat to external charging components, and the third type fan 110 can also dissipate heat to the entire accommodation chamber, thus enhancing the heat dissipation effect of the charging cabinet 1 .

In addition, in this embodiment, the positions and numbers of the second air inlet 108 and the air outlet 109 are not fixed.

Specifically, the second air inlet 108 and the air outlet 109 are determined according to the third type of fan 110 . That is, when the third type fan 110 is disposed near a vent other than the first air inlet 107 , the corresponding vent is constituted as the air outlet 109 . The vent constitutes the second air inlet 108 .

In addition, in this embodiment, only the air outlet 109 may be provided instead of the second air inlet 108 . In this way, the third type fan 110 can only inhale external air from the first air inlet 107 . At this time, if the first air inlet 107 is not connected to the battery pack 400, the gas flow rate sucked into the first chamber B is large and cold air. The wind from the air outlet 107 is the hot air after dissipating heat inside the battery pack 400 .

Of course, the above situation is a special situation. It is usually better to open the air outlet 109 and the second air inlet 108 at the same time on the housing 10. At the same time, the number of the air outlet 109 and the second air inlet 108 is not specifically limited. It can be understood that , the heat dissipation effect is better when the number of the air outlets 109 and the second air inlets 108 is larger. The number and position of the second air inlets 108 and the air outlets 109 are not specifically limited here and are subject to actual needs.

Further, in this embodiment, the second control unit 71 is electrically connected to the third type fan 110 to control the opening or closing of the third type fan 900 .

In addition, since the battery pack 400 and/or the power components begin to generate a large amount of heat when the charging cabinet 1 starts to work, in order to ensure that the temperature in the first chamber B is always at a low level, when the battery pack 400 starts charging and /Or when the energy storage device 2 starts to charge, that is, when at least one power component starts to work, the second control unit 71 controls the third type fan 110 to start working.

In an optional embodiment, a third temperature sensor can also be provided in the first chamber B. When the third temperature sensor detects that the first chamber B When the temperature inside is higher than the third preset threshold, the third type fan 110 is controlled to operate to cool down the first chamber B. In this embodiment, when the temperature in the charging cabinet 1 is low, the third type fan 110 is turned off to save energy consumption, and when the temperature in the charging cabinet 1 is too high, the third type fan 110 is started to operate to remove the charger. The hot air in the cabinet 1 is thereby reduced, thereby reducing the temperature of the charging cabinet 1; this not only saves energy consumption but also effectively dissipates heat from the charging cabinet 1. Furthermore, in this embodiment, the third threshold is 40°C. In other embodiments, the third threshold may also be 35°C, 45°C, etc. The size of the third threshold is not specifically limited here and shall be subject to the actual situation.

In this embodiment, the current internal air ducts of the battery pack 400 are complex and require high wind pressure. Therefore, the third type of fan 110 uses a centrifugal fan with a large air inlet pressure. In addition, in an optional embodiment, the third type of fan 110 may also be an axial flow fan.

Further, in this embodiment, one air outlet 109 is provided with a third type fan 110, and the area of the air outlet 109 is greater than or equal to the air outlet area of the third type fan 110 and smaller than the air outlet area of the third type fan 110. 1.2 times. In this way, it can not only meet the air outlet demand, but also avoid that when the area of the air outlet 109 is too large, the hot air sucked out from the third type fan 110 will be sucked into the first chamber B through the area where the third type fan 110 is not correspondingly installed. . In addition, in this embodiment, when the third type fan 110 is an axial flow fan, the air outlet area of the third type fan 110 is the area of a circle corresponding to the rotation of the blades. And when the third type fan 110 is a centrifugal fan, the air outlet area of the third type fan 110 is the air outlet area of the centrifugal fan.

In an optional embodiment, one air outlet 109 can also be provided with two or more third-type fans 110. The details are not limited here and are subject to actual needs.

Further, in this embodiment, the electrical module further includes a control unit configured to perform fault detection on at least one of the first type fan 90 , the second type fan 100 and the third type fan 110 , and when detecting Notify when a fault occurs. In this way, the operator can be informed when the fan fails, making it convenient for the operator to promptly discover the fan failure and perform corresponding processing.

Specifically, in this embodiment, the control unit includes a first control unit and a second control unit 71 , where the second control unit 71 is configured to control the first type of fan 90 , the second type of fan 100 and the third type of fan 110 Perform fault detection. When at least one of the first type fan 90 , the second type fan 100 and the third type fan 110 is detected to have a fault by the second control unit 71 , the second control unit 71 sends the fault information to an external communication device with a display function. equipment, external communication equipment displays faults. Among them, external communication devices can include: computers, mobile phones, bracelets, etc. External communication equipment can display faults through APP installed on computers, mobile phones, and bracelets. The fault display content can include: which fan failed, the time of failure, etc. In addition, in an optional embodiment, a display module can also be provided on the charging cabinet 1 to directly display faults through the display module. The display module may include: indicator lights, buzzers, etc., that is, fault information can be learned through the visual indication of the indicator light or the sound indication of the buzzer. The implementation method of fault information reporting is not specifically limited here, and is subject to actual design requirements.

Furthermore, in this embodiment, the distance between at least some of the vents and the bottom surface of the charging cabinet 1 is greater than or equal to 2 cm, so as to avoid placing the charging cabinet 1 on the ground when it rains and causing water to flow into the first chamber B from the vents 107 internal problems. Specifically, in this embodiment, the distance between at least part of the air outlet 109 and/or the second air inlet 108 and the bottom surface of the charging cabinet 1 is greater than 2 cm.

In addition, in this embodiment, the air outlet 109 is provided on the side wall 1011 of the housing, which not only avoids the problem of easy entry of rainwater provided on the top wall of the housing body 1 . At the same time, when using the charging cabinet 1, the operator usually stands in front of the first door 102 and faces the first door 102 to operate. If the air outlet 109 is provided on the first door 102, it will affect the appearance. properties, and the hot gas will interfere with the operator when flowing out from the air outlet 109, affecting the operator's experience and heat dissipation effect.

Further, in this embodiment, at least part of the air outlet 109 and at least part of the second air inlet 108 are respectively provided on the opposite side walls 1011. In this way, after the third type fan 110 starts working, the gas circulates between the second air inlet 108 and the air outlet 109 located on the two opposite side walls 1011 and in the first chamber B, making the gas path long and resistant. Smaller to improve heat dissipation.

Further, in this embodiment, the second air inlet 108 and the air outlet 109 are located behind the first type of fan and in front of the second type of fan, This prevents the gas from being blocked when flowing in the first chamber B, thereby improving the heat dissipation effect.

Further, in this embodiment, the accommodation chamber is divided into a first chamber and a second chamber by a partition 104 , the first door 102 constitutes the front wall of the housing 10 , and the partition 104 constitutes the rear wall of the housing 10 .
