[0022] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] Please refer to Figure 1-Figure 2 As shown, the present application proposes a field lamp 1 , which can effectively improve the endurance of the field lamp 1 .

[0024] The field lamp 1 includes a base 10, a main energy storage module (not shown in the figure), a secondary energy storage module 20 and a control module (not shown in the figure). The base 10 has a receiving cavity (not shown in the figure), a mounting groove 113 is provided on the bottom surface of the base 10, and a first interface 111 for connecting an external electrical device is provided on the side of the base 10. The main energy storage module is located in the receiving cavity and connected to the base 10, and the main energy storage module is electrically connected to the first interface 111. The secondary energy storage module 20 is connected to the base 10 corresponding to the mounting groove 113, and the secondary energy storage module 20 is electrically connected to the first interface 111. The control module is located in the accommodating cavity and is electrically connected to the main energy storage module and the auxiliary energy storage module 20. The control module compares the current power of the auxiliary energy storage module 20 with its preset threshold power. When the current power of the auxiliary energy storage module 20 is less than or equal to the threshold power, the field light 1 is in a first power supply mode. In the first power supply mode, the control module controls the main energy storage module to supply power to the external electrical equipment alone. When the current power of the auxiliary energy storage module 20 is greater than the threshold power, the field light 1 is in a second power supply mode. In the second power supply mode, the control module controls the auxiliary energy storage module 20 to supply power to the external electrical equipment alone.

[0025] The following combination Figure 1-Figure 4 The specific structure of the field lamp 1 is introduced in detail.

[0026] The field lamp 1 includes a base 10 , a main energy storage module (not shown in the figure), a secondary energy storage module 20 and a control module (not shown in the figure).

[0027] like Figure 1-Figure 2 As shown, the base 10 serves as the base of the field lamp 1, and is used to support structural parts such as the lamp head of the field lamp 1 (the light source of the field lamp 1, used to emit light to the outside to illuminate the surrounding environment); there is no limitation on the specific shape of the base 10, and designers can make a reasonable design based on actual needs; there is no limitation on the specific material of the base 10, and designers can make a reasonable choice based on actual needs.

[0028] The base 10 has a accommodating cavity (not shown in the figure), which is a hollow area inside the base 10 and is used to accommodate structural parts such as a main energy storage module or a circuit board of the field light 1. The specific shape of the accommodating cavity is not limited here, and designers can make reasonable designs according to actual needs.

[0029] The bottom surface of the base 10 is provided with a mounting groove 113, which is a groove formed inwardly from the bottom surface of the base 10 and is used to accommodate structural parts such as the auxiliary energy storage module 20. The specific shape of the mounting groove 113 is not limited here, and designers can make reasonable designs according to actual needs.

[0030] A first interface 111 for connecting to an external power-consuming device is disposed on a side surface of the base 10 , that is, the main energy storage module or the auxiliary energy storage module 20 transmits power to the external power-consuming device through the first interface 111 .

[0031] The main energy storage module is one of the power collection stations of the field light 1. The main energy storage module is electrically connected to the first interface 111, that is, the main energy storage module can release power to external power devices (such as mobile phones) through the first interface 111, and can also store power from an external power source (such as a power bank). The main energy storage module can include, but is not limited to, a battery.

[0032] The main energy storage module is located in the accommodating cavity and is connected to the base 10; wherein the main energy storage module and the base 10 may be detachably connected or non-detachably connected; for example, when the main energy storage module and the base 10 are detachably connected, the main energy storage module may be connected to the base 10 by at least one of screw connection, snap connection or plug-in connection, etc.; for example, when the main energy storage module and the base 10 are non-detachably connected, the main energy storage module may be connected to the base 10 by at least one of gluing or welding, etc., etc., but is not limited to the like.

[0033] like Figure 3-Figure 4 As shown, the auxiliary energy storage module 20 serves as another power collection station for the field lamp 1. The auxiliary energy storage module 20 is electrically connected to the first interface 111, that is, the auxiliary energy storage module 20 can release power to external power devices (such as mobile phones) through the first interface 111, and can also store power from an external power source (such as a power bank). Among them, the auxiliary energy storage module 20 can include, but is not limited to, a battery. It should be noted that the auxiliary energy storage module 20 and the main energy storage module can be the same or different in parameters such as rated voltage, rated current, and rated capacity.

[0034] The auxiliary energy storage module 20 is connected to the base 10 corresponding to the mounting groove 113; wherein, the auxiliary energy storage module 20 and the base 10 may be detachably connected or non-detachably connected; for example, when the auxiliary energy storage module 20 and the base 10 are detachably connected, the auxiliary energy storage module 20 may be connected to the base 10 by at least one of screw connection, card connection or plug connection, etc., but not limited to; for example, when the auxiliary energy storage module 20 and the base 10 are non-detachably connected, the auxiliary energy storage module 20 may be connected to the base 10 by at least one of adhesive connection or welding, etc., but not limited to. The specific connection method between the auxiliary energy storage module 20 and the base 10 will be described in detail below.

[0035] like Figure 1-Figure 2 As shown, the control module is a structural component used in the field lamp 1 to control the main energy storage module or the auxiliary energy storage module 20 to supply power to external electrical equipment, or to control the main energy storage module or the auxiliary energy storage module 20 to receive power from an external power supply. The control module is located in the accommodating cavity and is electrically connected to the main energy storage module and the auxiliary energy storage module 20. This does not limit the specific structure of the control module, and designers can make reasonable designs according to actual needs. For example, the control module can include, but is not limited to, an MCU (Microcontroller Unit).

[0036] The control module can monitor the current power of the auxiliary energy storage module 20 in real time, and the control module is used to compare the current power of the auxiliary energy storage module 20 with its preset threshold power. It should be noted that the specific meaning of "threshold power" is not limited here, and the designer can set it in advance according to actual needs; for example, "threshold power" can be understood as the minimum power of the auxiliary energy storage module 20 that can be used for external electrical equipment to work (such as working at 20% of the rated power), and "threshold power" can also be understood as the minimum power of the auxiliary energy storage module 20 that can be used for the normal operation of external electrical equipment (such as working at rated power).

[0037] When the current power of the auxiliary energy storage module 20 is less than or equal to the preset threshold power, the field light 1 is in the first power supply mode, in which the control module controls the main energy storage module to supply power to the external power device alone; when the current power of the auxiliary energy storage module 20 is greater than the corresponding preset threshold power, the field light 1 is in the second power supply mode, in which the control module controls the auxiliary energy storage module 20 to supply power to the external power device alone. In other words, as long as there is a situation where the current power of the auxiliary energy storage module 20 is greater than the preset threshold power, the control module will control the auxiliary energy storage module 20 to supply power to the external power device in priority to the main energy storage module, until the current power of the auxiliary energy storage module 20 is less than or equal to the above-mentioned preset threshold power, the control module will control the auxiliary energy storage module 20 to stop supplying power to the external power device, and as long as the external power device still has power demand, the control module will control the main energy storage module to continue to supply power to the external power device alone.

[0038] Based on the field light 1 in the embodiment of the present application, by designing a secondary energy storage module 20, the secondary energy storage module 20 can supply power to external electrical equipment through the first interface 111, so that the overall battery capacity of the field light 1 is larger, which can effectively improve the endurance of the field light 1 and can be suitable for more application scenarios. By setting a control module to compare the current power of the auxiliary energy storage module 20 with the preset threshold power, and when the current power of the auxiliary energy storage module 20 is greater than the preset threshold power, the control module controls the auxiliary energy storage module 20 to supply power to the external power device alone, so that the field lamp 1 is in the second power supply mode in which the auxiliary energy storage module 20 supplies power to the external power device alone rather than the main energy storage module, and until the current power of the auxiliary energy storage module 20 is less than or equal to the corresponding preset threshold power, the control module will control the main energy storage module to supply power to the external power device alone, so that the field lamp 1 is in the first power supply mode. With such a design, the field lamp 1 not only has its own lighting function, but also realizes uninterrupted power supply to the external power device by switching between the auxiliary energy storage module 20 and the main energy storage module, so that the field is also equivalent to a mobile power supply, which can provide power supply needs for users, thereby effectively enhancing the convenience of using the field lamp 1.

[0039] Further, the preset threshold power of the auxiliary energy storage module 20 is 5% to 10% of the rated power of the auxiliary energy storage module 20. That is to say, when the control module detects that the current power of the auxiliary energy storage module 20 is less than or equal to 5% to 10% of the rated power of the auxiliary energy storage module 20, if the external power device has a power demand, then the control module will control the main energy storage module to supply power to the external power device alone; conversely, when the control module detects that the current power of the auxiliary energy storage module 20 is greater than 5% to 10% of the rated power of the auxiliary energy storage module 20, if the external power device has a power demand, then the control module will preferentially control the auxiliary energy storage module 20 to supply power to the external power device alone. Among them, the preset threshold power of the auxiliary energy storage module 20 can be, but is not limited to, 5%, 6%, 7%, 8%, 9% or 10% of the rated power of the auxiliary energy storage module 20.

[0040] Furthermore, if Figure 1-Figure 2 As shown, the type of the first interface 111 is a type-C interface, and the field lamp 1 also has a charging mode. In the charging mode, the first interface 111 is used to connect an external power supply, and the control module controls the external power supply to preferentially supply power to the main energy storage module through the first interface 111 until the current power of the main energy storage module is equal to its rated power, and the external power supply then supplies power to the auxiliary energy storage module 20 through the first interface 111. In other words, when the field lamp 1 is in the charging mode, as long as the current power of the main energy storage module has not reached its rated power, the control module will control the external power supply to preferentially supply power to the main energy storage module until the current power of the main energy storage module reaches its rated power, and the control module will control the external power supply to supply power to the auxiliary energy storage module 20. In the embodiment of the present application, the Type-C interface can support 15W (5V / 3A) or 18W (9V / 2A, 12V / 1.5A) fast charging.

[0041] By designing the first interface 111 as a type-C interface, when the power of the external power device is low or zero, the type-C interface is connected to the external power device, and the power released by the main energy storage module or the auxiliary energy storage module 20 is transmitted to the external power device through the type-C interface. At this time, the field light 1 can also serve as a mobile power source for discharging to the external power device. When the power of the main energy storage module or the auxiliary energy storage module 20 is low or zero, the Type-C interface is connected to the external power source, and the power released by the external power source is transmitted to the main energy storage module or the auxiliary energy storage module 20 through the Type-C interface, so that the external power source can charge the main energy storage module or the auxiliary energy storage module 20.

[0042] Furthermore, if Figure 1-Figure 2As shown, the field lamp 1 has a symmetric plane, and the main energy storage module and the auxiliary energy storage module 20 are arranged on both sides of the symmetric plane, and the main energy storage module is closer to the first interface 111 than the auxiliary energy storage module 20. For example, when the base 10 is in a rectangular parallelepiped shape, the symmetric plane can be a plane perpendicular to the length direction of the base 10, and the main energy storage module and the auxiliary energy storage module 20 are spaced apart along the length direction of the base 10. In this way, on the one hand, the normal charging and discharging of the main energy storage module and the auxiliary energy storage module 20 can be guaranteed; on the other hand, the heat released during the operation of the main energy storage module and the auxiliary energy storage module 20 can be evenly distributed, effectively avoiding the occurrence of local overheating of the field lamp 1; on the other hand, the configuration distribution of the main energy storage module and the auxiliary energy storage module 20 on the base 10 can be relatively even, effectively avoiding the occurrence of tilting and tipping of the field lamp 1.

[0043] Furthermore, if Figure 1-Figure 2 As shown, the side of the base 10 is also provided with a second interface 112 adjacent to the first interface 111, and the second interface 112 is electrically connected to the main energy storage module and the auxiliary energy storage module 20, and the type of the second interface 112 is a USB-A interface. In the embodiment of the present application, the USB-A interface can support 15W (5V / 3A) or 18W (9V / 2A, 12V / 1.5A) mobile power output.

[0044] By designing the second interface 112 as a USB-A interface, when the power of the external power device is low or zero, the USB-A interface is connected to the external power device, and the power released by the main energy storage module or the auxiliary energy storage module 20 is transmitted to the external power device through the USB-A interface. At this time, the field lamp 1 is equivalent to a mobile power supply, and the main energy storage module or the auxiliary energy storage module 20 discharges to the external power device. It should be noted that when the field lamp 1 has a first interface 111 and a second interface 112, the user can select at least one of the interfaces to connect the external power device so that the main energy storage module or the auxiliary energy storage module 20 supplies power to the external power device. In addition, when both the first interface 111 and the second interface 112 are connected to an external power device, as long as the current power of the auxiliary energy storage module 20 is greater than its preset threshold power, the control module preferentially selects the auxiliary energy storage module 20 to supply power to multiple external power devices at the same time, until the current power of the Fu energy storage module is less than or equal to its preset threshold power, the control module will control the main energy storage module to supply power to multiple external power devices at the same time.

[0045] Furthermore, if Figure 3-Figure 4 As shown, the secondary energy storage module 20 is detachably connected to the base 10. By designing the secondary energy storage module 20 to be detachably connected to the base 10, when the current power of the secondary energy storage module 20 is less than or equal to its preset threshold power, the user can remove the secondary energy storage module 20 from the base 10 and use an external power source to charge the removed secondary energy storage module 20 separately.

[0046] Specifically, the groove wall of the installation groove 113 is provided with a bayonet 1131, and the auxiliary energy storage module 20 includes an energy storage body and a bayonet flange 22, and the bayonet flange 22 is engaged with the bayonet 1131 to position the auxiliary energy storage module 20 on the base 10. When the bayonet flange 22 is engaged with the bayonet 1131, the relative fixation of the position between the auxiliary energy storage module 20 and the base 10 can be achieved, and when the bayonet flange 22 is disengaged from the bayonet 1131, the relative change of the position between the auxiliary energy storage module 20 and the base 10 can be achieved, thereby achieving a detachable connection between the auxiliary energy storage module 20 and the base 10.

[0047] Furthermore, if Figure 3-Figure 4 As shown, the auxiliary energy storage module 20 has a third interface 23, and the auxiliary energy storage module 20 is electrically connected to the first interface 111 through the third interface 23 (when the base 10 has a second interface 112, the auxiliary energy storage module 20 is also electrically connected to the second interface 112 through the third interface 23). When the current power of the auxiliary energy storage module 20 is less than or equal to its preset threshold power, the auxiliary energy storage module 20 is connected to the external power supply through the third interface 23, so that the external power supply supplies power to the auxiliary energy storage module 20. It should be noted that after the auxiliary energy storage module 20 is removed from the base 10, the control module will regard the current power of the auxiliary energy storage module 20 detected by the control module as zero. If the external power-consuming device has a power demand, the control module will control the main energy storage module to supply power to the external power-consuming device.

[0048] Among them, the type of the third interface 23 is a type-C interface. By designing the third interface 23 as a type-C interface, when the power of the external power device is low or zero, the third interface 23 is connected to the external power device through the first interface 111, and the electric energy released by the auxiliary energy storage module 20 is transmitted to the external power device through the third interface 23 and the first interface 111, so as to discharge to the external power device. When the power of the auxiliary energy storage module 20 is low or zero, the third interface 23 can be directly connected to the external power supply, and the electric energy released by the external power supply is transmitted to the auxiliary energy storage module 20 through the third interface 23, so as to realize the external power supply charging the auxiliary energy storage module 20.

[0049] Furthermore, if Figure 2-Figure 3As shown, the base 10 includes a base body 11 and a cover body 12, the base body 11 has the above-mentioned accommodating cavity, the bottom surface of the base body 11 is provided with a mounting groove 113, the side surface of the base body 11 is provided with a first interface 111, and the cover body 12 is connected to the base body 11 corresponding to the mounting groove 113 to cover the notch of the mounting groove 113. Among them, the cover body 12 can be connected to the base body 11 by means of, but not limited to, locking screws, snaps, etc. By designing the cover body 12, when the cover body 12 opens the notch of the mounting groove 113, the auxiliary energy storage module 20 is exposed, and the user can remove the auxiliary energy storage module 20 from the base 10, and use the third interface 23 to allow an external power supply to charge the auxiliary energy storage module 20; when the cover body 12 closes the notch of the mounting groove 113, the auxiliary energy storage module 20 is blocked, and the cover body 12 plays a role such as dustproof or waterproof for the auxiliary energy storage module 20 on the one hand, and protects the auxiliary energy storage module 20 on the other hand.
