[0029] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0030] like Figures 1 to 3 As shown, this embodiment provides a virtual power plant IoT access device with security protection function, including: access housing 1, motherboard 2, multiple functional modules 3 and multiple snap-fit ​​mechanisms 4. The motherboard 2 is fixedly installed in the access housing 1, the multiple snap-fit ​​mechanisms 4 are spaced apart and fixedly installed on the motherboard 2, the multiple functional modules 3 are snapped into the multiple snap-fit ​​mechanisms 4 one by one, and the functional modules 3 are electrically connected to the motherboard 2.

[0031] It should be noted that in this embodiment, when the functional module 3 engages with the latching mechanism 4, the electrodes on the functional module 3 simultaneously contact the electrodes on the motherboard 2 to achieve electrical connection for data transmission.

[0032] The beneficial effects of this utility model are: multiple snap-fit ​​mechanisms are spaced apart and fixedly installed on the motherboard, and multiple functional modules are snapped into the multiple snap-fit ​​mechanisms one by one. This makes it easier to remove a functional module from the motherboard for replacement or repair when it is damaged, by canceling the snap-fit ​​between the module and the snap-fit ​​mechanism. This reduces the difficulty of replacing and repairing functional modules in the access device and improves the efficiency of replacement and repair.

[0033] Preferred, such as Figure 3As shown, the latching mechanism 4 includes: two first latching plates 41, two levers 42, and a first spring 43. The two first latching plates 41 are arranged vertically at intervals, and their rear ends are fixedly installed on the front side of the main board 2. The levers 42 are L-shaped rod structures, and one end of each of the two levers 42 is fixedly connected to the front side wall of the two first latching plates 41. The first spring 43 is arranged between the two first latching plates 41, and its top and bottom ends are fixedly connected to the two first latching plates 41. The two first latching plates 41 are latched to the top and bottom ends of the functional module 3.

[0034] It should be noted that in this embodiment, the first snap-fit ​​plate 41 has a certain elastic deformation, that is, it can return to its original position after being deformed by force. When the first spring 43 is engaged with the first latching plate 41 and the functional module 3, it is in a compressed state or in its natural length state. When the two levers 42 are moved toward each other, the front ends of the two first latching plates 41 are moved toward each other, thereby causing the first spring 43 to be in a compressed state.

[0035] The beneficial effect of adopting the above preferred solution is that by moving the two levers toward each other, it is beneficial to move the front ends of the two first snap-fit ​​boards closer to each other, thereby canceling the snap-fit ​​relationship between the two first snap-fit ​​boards and the functional module, thus making it easier to remove the damaged functional module from the motherboard for replacement and repair.

[0036] Preferred, such as Figure 3 As shown, a first engaging boss 411 is fixedly installed on the side of the front end of the two first engaging plates 41 that are far apart from each other. The two first engaging bosses 411 are engaged with the top and bottom ends of the functional module 3 respectively.

[0037] The advantages of adopting the above preferred scheme are: the two first engaging bosses facilitate the engagement with the top and bottom of the functional module.

[0038] Preferred, such as Figure 3 As shown, the top and bottom of the functional module 3 are both fixedly installed with second snap-fit ​​plates 31. The rear ends of the two second snap-fit ​​plates 31 are fixedly installed with second snap-fit ​​protrusions 32 on the side that are close to each other. The two second snap-fit ​​protrusions 32 are adapted to and snap-fit ​​with the two first snap-fit ​​protrusions 411.

[0039] The advantages of adopting the above preferred solution are: the two second engaging protrusions correspond one-to-one with the two first engaging protrusions, which helps to fix the functional module on the engaging mechanism and then on the motherboard.

[0040] Preferred, such as Figure 1 and Figure 2 As shown, the access housing 1 includes: an outer shell 11, an inspection window 12, two latches 13, and a fingerprint reader 14. The outer shell 11 is a box structure with an open front end. The two latches 13 are spaced apart vertically and fixedly installed on one side wall of the front end of the outer shell 11. The inspection window 12 is a transparent plate, one side of which is hinged to the other side wall of the front end of the outer shell 11, and the other side of which is detachably connected to one side wall of the front end of the outer shell 11 through the two latches 13. The fingerprint reader 14 is fixedly installed on the side wall of the outer shell 11 and electrically connected to the two latches 13. The main board 2 is disposed inside the outer shell 11 and fixedly installed on the rear side wall of the outer shell 11.

[0041] It should be noted that in this embodiment, during the electrical connection between the fingerprint reader 14 and the two latches 13, when the fingerprint detected by the fingerprint reader 14 matches the preset fingerprint, the fingerprint reader 14 controls the two latches 13 to open. The signal transmission between the fingerprint reader 14 and the latches 13, as well as the fingerprint information detection of the fingerprint reader 14 itself, are all existing technologies.

[0042] The advantages of adopting the above-mentioned preferred solution are: the inspection window is a transparent panel, which allows staff to know the status of the functional modules inside the access housing without opening the access housing; the lock combined with the fingerprint reader ensures that only staff can open the access housing, thus ensuring the security of the access device.

[0043] Preferred, such as Figure 2 As shown, the lower side wall of the outer casing 11 is provided with a plurality of wire holes 111 at intervals. The wire holes 111 are through holes. The lower end of the main board 2 is fixedly connected to a circuit terminal block 21. The bottom end of the circuit terminal block 21 is fixedly connected with a plurality of connecting wires 22 at intervals. The plurality of connecting wires 22 pass through the plurality of wire holes 111 one by one.

[0044] The advantage of adopting the above preferred solution is that the connecting cable passes through the cable hole, which facilitates signal transmission between external devices and functional modules on the motherboard.

[0045] Preferred, such as Figure 1 and Figure 2 As shown, multiple indicator lights 5 are also fixedly installed on the motherboard 2, and each of the multiple indicator lights 5 is electrically connected to one of the multiple functional modules 3.

[0046] The advantages of adopting the above preferred solution are: indicator lights help to quickly and accurately locate the damaged functional module when a certain functional module is damaged, saving repair time.

[0047] Preferred, such as Figure 2 , Figure 4 and Figure 5 As shown, it also includes a fixing mechanism 6 for fixing the access housing 1, the fixing mechanism 6 being installed on the rear side of the access housing 1.

[0048] It should be noted that in this embodiment, the fixing mechanism 6 is installed on the rear side of the outer casing 11.

[0049] The advantages of adopting the above preferred solution are: the fixing mechanism is installed on the rear side of the access housing, which is conducive to fixing the access housing and the various components installed inside it on other external devices, thus solving the problem of cumbersome installation process and poor adaptability of the access device.

[0050] Preferably, the fixing mechanism 6 is a magnet, and the fixing mechanism 6 is attached to the rear side of the metal access housing 1.

[0051] It should be noted that in this embodiment, the fixing mechanism 6 is attached to the rear side of the metal outer shell 11.

[0052] The advantages of adopting the above preferred solution are that the magnet allows the access device to be directly installed on a metal body such as a distribution box or on a steel plate installed on the wall of a power distribution room by magnetic attraction.

[0053] Preferred, such as Figure 4 and Figure 5As shown, the fixing mechanism 6 includes: a mounting plate 61, at least two connecting strips 62, multiple connecting pipes 63, multiple locking elements 64, multiple locking bolts 65, and multiple second springs 66; the mounting plate 61 is evenly provided with multiple locking holes 612, each locking hole 612 being a through hole, and multiple locking bolts 65 passing through the multiple locking holes 612 one by one; the connecting strips 62 are U-shaped strip structures with their openings facing forward, two connecting strips 62 are spaced apart, and their rear sides are fixedly connected to the front side of the mounting plate 61; the connecting pipes 63 are fixedly installed on the rear side plate of the connecting strips 62 and pass through the connecting strips 62; the rear ends of multiple second springs 66 are fixedly connected to the inner wall of the front end of the connecting pipes 63 one by one; the mounting plate 61 is provided with multiple mounting through holes 611, each mounting through hole 611 being a strip-shaped through hole and communicating with the connecting pipes 63; the locking elements 64... The connecting pipe 63 and the mounting through hole 611 are coaxially arranged. The rear side of the mounting plate 61 is provided with multiple mounting grooves 613, which are perpendicular to the mounting through holes 611. The locking member 64 includes a locking rod 641, a locking block 642, and a handle 643. The locking block 642 and the handle 643 are fixedly installed on the rear end and front end of the locking rod 641, respectively. Multiple second springs 66 are sleeved on the locking rods 641, and the front ends of the multiple second springs 66 are fixedly connected to the side wall of the locking rod 641. The locking block 642 passes through the connecting pipe 63 and the mounting through hole 611 in sequence and is adapted to be disposed in the mounting groove 613. The rear side of the access housing 1 is sleeved on the locking rod 641 and abuts against the handle 643 and the front ends of the left and right side plates of the connecting strip 62.

[0054] It should be noted that in this embodiment, the rear side plate of the outer shell 11 is sleeved on the locking rod 641, the rear end of the rear side plate of the outer shell 11 abuts against the front end of the left and right side plates of the connecting strip 62, and the front end of the rear side plate of the outer shell 11 abuts against the handle 643, which is beneficial to fix the access shell to the mounting plate by the locking member. Because the space inside the housing 11 is relatively narrow after the motherboard 2 is fixedly installed in the housing 11, it is inconvenient to disassemble and assemble if the housing 11 is directly fixed to the external device with bolts. Instead, it is more convenient to first use the locking member 64 to fix the housing 11 to the mounting plate 61, and then fix the mounting plate 61 to the external device. This makes it easier to remove the mounting plate 61 from the external device and then remove the housing 11 from the mounting plate 61.

[0055] The advantages of adopting the above preferred solution are: the locking bolts facilitate fixing the mounting plate to other external devices, and the locking element facilitates fixing the access housing to the mounting plate. Thus, when there is no suitable magnetic body, the access device can be fixed to the external device, solving the problem of cumbersome installation process and poor adaptability of the access device.

[0056] The working process of this embodiment is described below: like Figures 1 to 3 As shown, when a certain functional module 3 is damaged, the corresponding indicator light 5 will light up or turn off, and the staff can find out which functional module 3 is damaged through the inspection window 12. First, the staff enters their fingerprint on the fingerprint reader 14. After successful verification, the fingerprint reader 14 controls the latch 13 to open, thereby opening the outer shell 11. Then, using tweezers, move the two levers 42 in the latching mechanism 4 corresponding to the damaged functional module 3 toward each other, so that the front ends of the two first latching plates 41 are close to each other. At this time, the first spring 43 is compressed, and the two first latching bosses 411 and the two second latching bosses 32 are separated. Then the damaged functional module 3 can be easily removed from the latching mechanism 4 for repair or replacement. After removing the functional module 3, release the two levers 42. Under the rebound force of the first latching plate 41 and the auxiliary rebound force of the first spring 43, the two first latching plates 41 are moved away from each other to restore the initial state. Next, bring the two second engaging protrusions 32 in the new functional module 3 close together and press the two first engaging protrusions 411 together, or use tweezers again to move the two levers 42 toward each other, so that the front ends of the two first engaging plates 41 are close together. At this time, the first spring 43 is compressed again until the two first engaging protrusions 411 and the two second engaging protrusions 32 are engaged and fixed again. At this time, the first spring 43 uses its rebound force to further engage and fix the two first engaging protrusions 411 and the two second engaging protrusions 32 together.

[0057] like Figure 4 and Figure 5As shown, when it is necessary to fix the housing 1 and its internal components such as the motherboard 2, functional module 3, snap-fit ​​mechanism 4, and indicator light 5 to other external devices, if the external device is a metal body such as a power distribution box, or a steel plate installed on the wall of a power distribution room, the rear panel of the housing 11 can be directly attached to the external metal device using a magnet; if the external device is a non-metallic body, the handle 643 is manually held and the locking rod 641 is driven through the connecting pipe 63 and the mounting hole 611. During this process, the locking rod 641... 41. Compress the second spring 66, then turn the handle 643 so that the locking block 642 rotates 90 degrees and fits into the mounting groove 613. At this time, release the handle 643. The front end and rear end of the rear side wall of the outer shell 11 sleeved on the locking rod 641 abut against the front ends of the handle 643 and the left and right side plates of the connecting strip 62. The second spring 66 uses its rebound force to press the locking block 642 into the mounting groove 613. Then, pass the locking bolt 65 through the locking hole 612 and connect it to the external equipment by thread.

[0058] This utility model has the following beneficial effects: 1. In this utility model, by setting the internal part of the access device as a modular partition and setting corresponding indicator lights and snap-fit ​​mechanisms for each group of modules, the faulty functional module can be quickly and accurately located during maintenance. The snap-fit ​​mechanism enables quick disassembly and quick assembly, allowing the access device to be repaired quickly. This solves the problem of excessively long repair time when the functional modules in the access device are damaged.

[0059] 2. In this utility model, by setting a magnet on the rear side of the outer shell, the access device can be directly installed on a metal body such as a distribution box or on a steel plate installed on the wall of a power distribution room. When there is no suitable magnetic body, the access device is fixed to the mounting plate by multiple locking parts, and the mounting plate is fixed to the external equipment, which solves the problem of cumbersome installation process and poor adaptability of the access device.
