[0066] LED (light-emitting diode) display screens are commonly used outdoor display devices. Such outdoor display devices are usually provided with a power supply box to provide electrical energy for themselves.

[0067] In the related art, the box body and the box cover of the power box are both provided with electrical modules, and the electrical modules on the box cover and the box body are connected by wires, which easily leads to confusion in the wiring inside the power box.

[0068] Based on this, in the embodiment of the present application, the second electrical connector on the box cover can follow the rotation of the box cover to move to dock with or separate from the first electrical connector of the box body, so that the connection cables required between the box cover and the box body can be reduced through the cooperation of the first electrical connector and the second electrical connector, so as to improve the technical problem of confusing wiring inside the power box. A more detailed example will be given below.

[0069] Please refer to Figure 1 , Figure 1 This is a usage scenario diagram of the power box provided in the embodiment of the present application. First, the embodiment of the present application provides a power box, which can be used in an LED box. The power box can also be other outdoor equipment, household equipment, etc., which is not limited in the embodiment of the present application.

[0070] The power supply box may include a box body 100, a first electrical connector 200, a box cover 300, and a second electrical connector 400. The first electrical connector 200 is disposed on the box body 100. The box cover 300 is rotatably mounted on the box body 100. The second electrical connector 400 is disposed on the box cover 300 to rotate with the box cover 300. The first electrical connector 200 is located on the rotation path of the second electrical connector 400, so that the second electrical connector 400 can follow the rotation of the box cover 300 and move to dock with or separate from the first electrical connector 200.

[0071] Taking the case where the box cover 300 can rotate forward to close the box body 100 and can rotate backward to open the box body 100 as an example, when the box cover 300 rotates forward to close the box body 100, the second electrical connector 400 and the first electrical connector 200 can be docked to achieve electrical connection, and when the box cover 300 rotates backward to open the box body 100, the second electrical connector 400 and the first electrical connector 200 are separated. Furthermore, through the cooperation of the first electrical connector 200 and the second electrical connector 400, the electrical connection between the electrical components at the box body 100 and the electrical components at the box cover 300 can be achieved, thereby reducing the connection cables required between the box cover 300 and the box body 100, so as to improve the technical problem of confusing wiring inside the power box.

[0072] Furthermore, since the docking of the first electrical connector 200 and the second electrical connector 400 is achieved by closing the box cover 300, compared with manual wiring by the user, the embodiment of the present application not only makes the connection between the electrical components at the box body 100 and the electrical components at the box cover 300 easier, but also reduces the probability of user wiring errors, thereby improving the stability and reliability of the power box.

[0073] In addition, compared to using a longer and larger cable for electrical connection, the electrical connection method of the first electrical connector 200 and the second electrical connector 400 is conducive to the miniaturized design of the power box, and can also reduce the material and process costs of the power box.

[0074] Furthermore, since the longer cables are eliminated, the current link between the electrical components at the box body 100 and the electrical components at the box cover 300 can be shortened, thereby effectively reducing the risk of damage to the electrical components caused by the voltage difference and improving the circuit efficiency of the power box; at the same time, it can also avoid the increase in impedance and heat caused by cable bending, thereby reducing the risk of fire in the power box and ultimately improving the safety and reliability of the power box.

[0075] Below, before describing the connection structure of the first electrical connector 200 and the second electrical connector 400 by example, the electrical components at the box cover 300 and the box body 100 are described by example.

[0076] Please continue to refer to Figure 2 , Figure 2 for Figure 1 The X in the figure is a partial enlarged view. Taking the power supply box applied to the LED box as an example, the power supply box can also include a HUB board 500 and a power module 600. The HUB board 500 is arranged on the box body 100, and the power module 600 is arranged on the box cover 300.

[0077] Then, the first electrical connector 200 and the second electrical connector 400 can be used for docking to realize the electrical connection between the HUB board 500 and the power module 600. For example, the first electrical connector 200 and the HUB board 500 are electrically connected. The second electrical connector 400 and the power module 600 are electrically connected. Thus, when the box cover 300 rotates to close the box body 100, the electrical connection between the HUB board 500 and the power module 600 can be realized by docking the first electrical connector 200 and the second electrical connector 400.

[0078] Among them, the HUB board is an integrated circuit board, which is responsible for transmitting control signals and data signals to each module of the LED display screen, and also receives feedback signals from each module to complete the global control and data synchronization of the LED display screen. The HUB board is usually composed of FPGA (Field Programmable Gate Array) chip, driver IC (Integrated Circuit), power management module, etc.

[0079] It is understandable that in the embodiment of the present application, when the box cover is opened, the power module 600 on the box cover 300 can be directly disassembled and / or maintained independently, and the power module 600 on the box body 100 can be directly disassembled and / or maintained independently. In contrast, the power module 600 and the HUB board 500 are both stacked and arranged in the box body 100, and one of the power module 600 and the HUB board 500 is easy to interfere with the disassembly and maintenance of the other. It can be seen that the power box of the embodiment of the present application has the advantage of easy disassembly and maintenance.

[0080] It can also be understood that the front side of the LED box can be used to install the LED light board module, and the box cover 300 is usually located on the side of the box body 100 away from the LED light board module, so as to facilitate the opening and closing of the box cover 300 from the back of the LED light board module (which can also be understood as the back of the LED box). Therefore, compared with the HUB board 500 being arranged on the box cover 300, the HUB board 500 is arranged on the box body 100 in the embodiment of the present application, so that the distance between the HUB board 500 and the LED light board module is closer, so that the current link between the HUB board 500 and the LED light board module is also shorter, thereby reducing the wiring difficulty between the HUB board 500 and the LED light board module, and improving the stability of the connection between the HUB board 500 and the LED light board module.

[0081] Of course, since the box cover 300 can also form part of the outer surface of the LED box (such as the rear side surface), the power module 600 is arranged at the box cover 300, which can make the heat dissipation path between the power module 600 and the air outside the LED box shorter, thereby improving the heat dissipation effect of the power box and the entire LED box.

[0082] Optionally, the first electrical connector 200 and the second electrical connector 400 may also be used for electrical connection of other electrical components, which is not limited in the embodiment of the present application.

[0083] Next, the structures of the first electrical connector 200 and the second electrical connector 400 according to the embodiment of the present application will be described with examples.

[0084] In some embodiments, the first electrical connector 200 and the second electrical connector 400 are both conductive sheet structures.

[0085] Then, taking the first electrical connector 200 and the second electrical connector 400 used in the electrical connection between the power module 600 and the HUB board 500 as an example, compared with the connection terminal of the data interface, the cross-sectional area of ​​the conductive sheet is larger, so that the current flow capacity and the load capacity of the first electrical connector 200 and the second electrical connector 400 are stronger. Therefore, when the power module 600 and the HUB board 500 transmit electric energy through the first electrical connector 200 and the second electrical connector 400, the energy efficiency and safety of the electric energy transmission can be improved.

[0086] In addition, the structure of the conductive sheet can also effectively reduce the manufacturing difficulty and manufacturing cost of the first electrical connector 200 and the second electrical connector 400. Therefore, the first electrical connector 200 and the second electrical connector 400 not only meet the actual needs of safety and reliability, but also have the advantage of low manufacturing cost and are more suitable for industrial production.

[0087] Please combine Figure 2 and Figure 3 , Figure 3 for Figure 1 Cutaway view of the power supply box shown Figure 1 In some embodiments, the first electrical connector 200 includes at least one first conductive sheet 21, and the width L2 of the first conductive sheet 21 is greater than or equal to 4 mm, thereby ensuring that the cross-sectional area of ​​the first electrical connector 200 is large enough to have sufficient current flow capacity and load carrying capacity.

[0088] For example, the width L2 of the first conductive sheet 21 may be 4 mm, 4.32 mm, 4.5 mm, 4.86 mm, 5 mm, 5.5 mm, 6 mm, 6.14 mm, 6.44 mm, 7 mm, 7.5 mm, 8 mm, 9.5 mm or 10 mm, which is not limited to the embodiments of the present application.

[0089] The second electrical connector 400 includes at least one second conductive sheet 41 , and the width L1 of the second conductive sheet 41 is greater than or equal to 4 mm, thereby ensuring that the cross-sectional area of ​​the second electrical connector 400 is large enough to have sufficient current flow capacity and load carrying capacity.

[0090] For example, the width L1 of the second conductive sheet 41 may be 4 mm, 4.32 mm, 4.5 mm, 4.86 mm, 5 mm, 5.5 mm, 6 mm, 6.14 mm, 6.44 mm, 7 mm, 7.5 mm, 8 mm, 9.5 mm or 10 mm, which is not limited to the embodiments of the present application.

[0091] In some embodiments, the first electrical connector 200 includes at least two first conductive plates 21 , the second electrical connector 400 includes at least two second conductive plates 41 , and each first conductive plate 21 is matched with one second conductive plate 41 .

[0092] For example, the number of the first conductive sheet 21 and the number of the second conductive sheet 41 are both two. Therefore, one group of the first conductive sheet 21 and the second conductive sheet 41 is used as a connecting device for the live line, and the other group of the first conductive sheet 21 and the second conductive sheet 41 is used as a connecting device for the neutral line, thereby realizing the power transmission between the power module 600 and the HUB board 500.

[0093] Optionally, the number of the first conductive sheet 21 and the second conductive sheet 41 can also be three. The first group of the first conductive sheet 21 and the second conductive sheet 41 are used as the connection device of the live line, the second group of the first conductive sheet 21 and the second conductive sheet 41 are used as the connection device of the neutral line, and the third group of the first conductive sheet 21 and the second conductive sheet 41 are used as the connection device of the ground line, thereby realizing the power transmission between the power module 600 and the HUB board 500.

[0094] In some embodiments, the first electrical connector 200 (such as the first conductive sheet 21 of the first electrical connector 200) includes a first portion 211 and a second portion 212 spaced apart along a first direction. The first direction is parallel to the rotation axis of the box cover 300, so that the second electrical connector 400 can be inserted into or out of the first portion 211 and the second portion 212 following the rotation of the box cover 300.

[0095] For example, the first direction is the vertical direction, and the first part 211 and the second part 212 are arranged in a spaced relationship along the vertical direction. Accordingly, the rotation axis of the box cover 300 is also arranged in the vertical direction, so that the second electrical connector 400 can be driven to perform a circular motion in a horizontal plane during the rotation of the box cover 300, so that the second electrical connector 400 can be inserted into or separated from the first part 211 and the second part 212 during the rotation of the box cover 300.

[0096] Specifically, when the box cover 300 rotates to close the box body 100, the second electrical connector 400 performs a circular motion in the horizontal plane, and then gradually inserts (or cuts into) between the first part 211 and the second part 212 from one side in the width direction of the first part 211, and then the first part 211 and the second part 212 clamp the second electrical connector 400. Conversely, when the box cover 300 rotates to open the box body 100, the second electrical connector 400 performs a circular motion in the horizontal plane, and then gradually detaches (or cuts out) between the first part 211 and the second part 212 from one side in the width direction of the first part 211.

[0097] In some embodiments, the box body 100 has an installation cavity 11, and the second electrical connector 400 is disposed in the installation cavity 11. The first portion 211 is bent at one end close to the opening of the installation cavity 11 in a direction away from the second portion 212; and / or the second portion 212 is bent at one end close to the opening of the installation cavity 11 in a direction away from the first portion 211.

[0098] That is to say, only the end of the first part 211 close to the opening of the installation cavity 11 may be bent in the direction away from the second part 212, or only the end of the second part 212 close to the opening of the installation cavity 11 may be bent in the direction away from the first part 211, or both the end of the first part 211 close to the opening of the installation cavity 11 may be bent in the direction away from the second part 212 and the end of the second part 212 close to the opening of the installation cavity 11 may be bent in the direction away from the first part 211. The embodiments of the present application are not limited to this.

[0099] Therefore, a flared structure is formed between one end of the first portion 211 close to the opening of the installation cavity 11 and one end of the second portion 212 close to the opening of the installation cavity 11. At this time, even if the box cover 300 shakes up and down during the rotation process and causes the second electrical connector 400 to shift up and down, the second electrical connector 400 can easily enter the flared structure and then slide along the first portion 211 or the second portion 212 to be locked between the first portion 211 and the second portion 212.

[0100] In some embodiments, at least one third of the first portion 211 along the length direction is parallel to the second portion 212. Thus, the second electrical connector 400 can be clamped between the mutually parallel regions of the first portion 211 and the second portion 212, so that the mutually parallel regions of the first portion 211 and the second portion 212 are closely fitted to the second electrical connector 400, thereby ultimately increasing the contact area between the first electrical connector 200 and the second electrical connector 400, and ultimately increasing the current flow capacity and load carrying capacity at the connection between the first electrical connector 200 and the second electrical connector 400.

[0101] For example, along the direction close to the opening of the installation cavity 11, the middle of the first part 211 and the middle of the second part 212 are parallel to each other, and one end of the first part 211 close to the opening of the installation cavity 11 and one end of the second part 212 close to the opening of the installation cavity 11 are bent in directions away from each other.

[0102] It can also be understood that, as mentioned above, the width of the first electrical connector 200 is greater than or equal to 4 mm, and thus the widths of the first portion 211 and the second portion 212 may both be greater than or equal to 4 mm.

[0103] Optionally, in some other embodiments, one of the first electrical connector 200 and the second electrical connector 400 may be a male connector and the other a female connector.

[0104] The male head may be a USB (Universal Serial Bus) interface male head or an aviation interface male head, etc., and correspondingly, the female head may be a USB interface female head or an aviation interface female head, etc., which is not limited in the embodiments of the present application.

[0105] Of course, in some other implementations, one of the first electrical connector 200 and the second electrical connector 400 may be a pogo pin and the other may be a conductive sheet or a conductive contact, etc. This embodiment of the present application is not limited to this.

[0106] The above are some examples of the first electrical connector 200 and the second electrical connector 400 in the embodiment of the present application. The following will continue to illustrate with examples in combination with other structures in the embodiment of the present application.

[0107] Please continue to refer to Figure 4 and Figure 5 , Figure 4 for Figure 1 The schematic diagram of the structure of the third electrical connector in the power supply box is shown. Figure 5 for Figure 1 Cutaway view of the power supply box shown Figure 2 In some embodiments, the power supply box may further include a third electrical connector 700 and a fourth electrical connector 800. The third electrical connector 700 is disposed on the box body 100. The fourth electrical connector 800 is disposed on the box cover 300 to rotate with the box cover 300. The third electrical connector 700 is located on the rotation path of the fourth electrical connector 800, so that the fourth electrical connector 800 can move to connect or separate with the third electrical connector 700 following the rotation of the box cover 300.

[0108] Then, a part of the connecting cables between the box cover 300 and the box body 100 can be reduced by the cooperation of the first electrical connector 200 and the second electrical connector 400, and another part of the connecting cables between the box cover 300 and the box body 100 can be reduced by the cooperation of the third electrical connector 700 and the fourth electrical connector 800, thereby further improving the technical problem of confusing wiring inside the power box.

[0109] In some embodiments, the first electrical connector 200 and the third electrical connector 700 are of different types. Thus, different types of electrical connectors can be used to meet different connection requirements at the box cover 300.

[0110] In some embodiments, one of the third electrical connector 700 and the fourth electrical connector 800 is a male connector and the other is a female connector, so that the third electrical connector 700 can move to be plugged in or separated from the fourth electrical connector 800 following the rotation of the box cover 300.

[0111] It is understandable that, compared with the conductive sheet type electrical connector, the male and female type electrical connectors have more pins, so that the male and female type electrical connectors are more suitable for signal transmission. That is, different pins of the male or female connector can be used to transmit different data signals, so that a male connector and a female connector can be plugged together to achieve the transmission of multiple data signals.

[0112] Please continue to refer to Figure 6 , Figure 6 for Figure 4 The schematic diagram of the structure of the third electrical connector and the fourth electrical connector is shown. In the third electrical connector 700 and the fourth electrical connector 800, the size of the female plug hole can be larger than that of the male plug, so that the male plug can be inserted into the female plug at a certain inclination angle relative to the female plug; for example, the male plug can be configured to have an inclination angle of 17° to 25° with the female plug and can still be vertically inserted into the female plug, so that the rotation of the box cover 300 can drive the male plug to be smoothly inserted into the female plug.

[0113] In some embodiments, the third electrical connector 700 is electrically connected to the HUB board 500 , and the fourth electrical connector 800 is electrically connected to the power module 600 .

[0114] At this time, the HUB board 500 and the power module 600 can transmit strong electrical energy through the cooperation of the first electrical connector 200 and the second electrical connector 400, and transmit weak current control signals through the cooperation of the third electrical connector 700 and the fourth electrical connector 800.

[0115] For example, please continue to refer to Figure 7 , Figure 7 for Figure 4 The power module 600 includes an energy storage unit 61 and a power management unit 62. The energy storage unit 61 is used to store and provide electrical energy, and the energy storage unit 61 is electrically connected to the second electrical connector 400. The power management unit 62 is used to control the energy storage unit 61, and the power management unit 62 is electrically connected to the fourth electrical connector 800.

[0116] For example, the energy storage unit 61 may be a battery or any other energy storage element of the power module 600. The power pipeline unit may be used to control the current sharing backup, charging and discharging power, etc. of the energy storage unit 61, which is not limited in the embodiment of the present application.

[0117] The above are some examples of the connection method between the electrical components at the box cover 300 and the electrical components at the box body 100 in the embodiment of the present application. The following will continue to illustrate the technical solution of the embodiment of the present application in combination with the rotational connection method between the box body 100 and the box cover 300.

[0118] Please continue to refer to Figure 8 , Figure 8 for Figure 1 Schematic diagram of the connection structure between the box body and the box cover of the power box shown. In some embodiments, the power box further includes a first rotating connection member 12 and a second rotating connection member 31. The first rotating connection member 12 is disposed on the box body 100, and the second rotating connection member 31 is disposed on the box cover 300. The first rotating connection member 12 and the second rotating connection member 31 are rotatably connected so that the box cover 300 can be rotated to open or close the box body 100.

[0119] In some embodiments, at least one of the first rotating connector 12 and the second rotating connector 31 is an extruded part, so that the manufacturing cost of the first rotating connector 12 and / or the second rotating connector 31 can be reduced.

[0120] In some embodiments, the box body 100 includes a first bottom wall 13 and a plurality of first side walls 14, and the plurality of first side walls 14 protrude from the same side surface of the first bottom wall 13, so that the first bottom wall 13 and the plurality of first side walls 14 enclose a mounting cavity 11. The first bottom wall 13, the first rotating connector 12 and at least one first side wall 14 are integrally formed. Thus, compared with a hinge formed separately from the box body 100, the assembly tolerance caused by the assembly of the hinge and the box body 100 can be eliminated, so that the rotation accuracy of the box cover 300 can be improved, so that the first electrical connector 200 can be accurately docked with the second electrical connector 400, and the third electrical connector 700 can be accurately docked with the fourth electrical connector 800.

[0121] For example, the first rotating connector 12 is extended along the length direction of the box body 100, and the first bottom wall 13, the first rotating connector 12 and at least one first side wall 14 extending along the length direction of the box body 100 are integrally formed by extrusion or injection molding.

[0122] In some embodiments, the box cover 300 may be integrally formed with the second rotating connector 31. Thus, compared with a hinge formed separately from the box cover 300, the assembly tolerance caused by the hinge and the box cover 300 can be avoided, thereby improving the rotation accuracy of the box cover 300, so that the first electrical connector 200 can be accurately docked with the second electrical connector 400, and the third electrical connector 700 can be accurately docked with the fourth electrical connector 800.

The power supply box is arranged on the frame 900 so that the power supply box can be electrically connected to the LED light board module 92 mounted to the mounting positions 91.

[0124] Thus, multiple LED light board modules 92 can be assembled on the frame 900, so that the LED box and multiple LED light board modules 92 are spliced ​​to form an LED display screen, and the LED light board module 92 is powered by the power box, and / or the LED light board module 92 is controlled by the power box.

[0125] In some embodiments, the LED light board module 92 is installed on a side of the frame 900 facing away from the LED light board module 92 .

[0126] In some embodiments, the power box is disposed in the middle of the frame 900; optionally, the power box may also be disposed close to the side of the frame 900, which is not limited in the embodiments of the present application.
