The height of each module shell varies according to the number of internal parts. When installing, each module is usually embedded in each frame in the module box, and then the wiring is arranged. In the prior art, each frame in the module box is usually designed with a fixed size. In actual use, due to different installation requirements of different smart meters, the number and model of modules to be installed may be different, resulting in the module box not being universal, and there may be processing errors between the module and the module box, which may also cause the module and the frame to be incompatible.

DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Embodiment 1

[0048] Generally, the smart meter module 200 is a module box body 100 installed in a cabinet or horizontally, and the frame used to support the smart meter module 200 is of fixed size and cannot be adjusted. In order to solve this technical problem, embodiment 1 is proposed;

[0049] See also Figure 1-Figure 5An integrated module box of a smart meter includes a module box body 100, wherein a plurality of smart meter modules 200 and a plurality of mounting mechanisms 300 are arranged in the module box body 100, wherein the plurality of smart meter modules 200 are linearly arranged along a vertical direction, and the plurality of smart meter modules 200 have different heights;

[0050] The mounting mechanism 300 includes a supporting frame mechanism 400, and the supporting frame mechanism 400 includes a bottom plate 410, a column 420 is arranged on the bottom plate 410, and a top plate 430 is slidably arranged on the column 420, and a plurality of supporting frame mechanisms 400 are connected in sequence;

[0051] The installation mechanism 300 also includes a first automatic adjustment mechanism 600. When the smart meter module 200 is inserted along the front side of the bottom plate 410, the height of the top plate 430 is automatically adjusted by the first automatic adjustment mechanism 600 to fit the upper side of the smart meter module 200 to adapt to the height of the smart meter module 200.

[0052] In this embodiment: the module box body 100 is a cabinet structure. Several smart meter modules 200 can carry different smart meter components, such as modules with two-way multi-rate metering functions, user-side control function modules, two-way data communication function modules with multiple data transmission modes, and anti-theft function modules. According to different internal parts structures, several smart meter modules 200 have different heights. The same length of several smart meter modules 200 is a unified standard, and the widths can be different.

[0053] In the initial state, among the plurality of support frame mechanisms 400, the distance between the bottom plate 410 and the top plate 430 is the largest, and the installation sequence is from bottom to top. When installing the first smart meter module 200, align it with the bottommost bottom plate 410 and insert it backward as shown in the figure. When the smart meter module 200 slides along the upper surface of the bottom plate 410, it will automatically trigger the top plate 430 located a certain distance above it to move downward until the top plate 430 fits the upper surface of the smart meter module 200. Then install the subsequent smart meter modules 200, and the steps are the same.

[0054] Thereby, the sizes of several frames can be automatically adjusted to fit.

[0055] In two adjacent support frame mechanisms 400, a bottom plate 410 located on the upper side is fixed to the upper end of a top plate 430 located on the lower side. Figure 3 As shown, in order to avoid mutual obstruction between the columns 420, the installation positions of the two groups of columns 420 in two adjacent support frame mechanisms 400 are staggered, and correspondingly, holes larger than the top plate 430 are left at the staggered positions.

[0056] Embodiment 2

[0057] In order to realize the automatic lowering of the control-adjustable top plate 430 and considering that when a non-fixed frame is used, since a plurality of frames and a plurality of smart meter modules 200 are vertically stacked, how to make the supporting force be borne by the frame itself instead of the smart meter module 200, a second embodiment is proposed;

[0058] This embodiment is an improvement on the first embodiment. For details, please refer to Figure 3-Figure 10 The first automatic adjustment mechanism 600 includes a fixing frame 610 disposed on the bottom plate 410, a gas pressure rod assembly 620 is disposed on the fixing frame 610, a connecting plate 630 is disposed on the top plate 430, and an output end of the gas pressure rod assembly 620 is connected to the connecting plate 630;

[0059] The first automatic adjustment mechanism 600 further includes a trigger assembly 640. When the smart meter module 200 slides along the bottom plate 410 from the front side to the rear side, the trigger assembly 640 controls the operation of the gas pressure rod assembly 620 to adjust the height of the top plate 430.

[0060] The gas pressure rod assembly 620 includes an outer cylinder 621 disposed on the fixing frame 610, an inner cylinder 622 is disposed in the outer cylinder 621, a piston rod 623 is slidably disposed on the inner cylinder 622, a piston 624 is disposed on the piston rod 623, and the piston rod 623 is connected to the connecting plate 630;

[0061] The piston 624 divides the inner cavity of the inner cylinder 622 into a first chamber 625 and a second chamber 626. The inner wall of the outer cylinder 621 and the outer wall of the inner cylinder 622 form a third chamber 627. The inner cylinder 622 is provided with a first through hole 628 and a second through hole 629. The first chamber 625 is connected to the third chamber 627 through the first through hole 628, and the second chamber 626 is connected to the third chamber 627 through the second through hole 629.

[0062] An elastic metal sheet 210 is disposed on the upper side of the smart meter module 200 , and the elastic metal sheet 210 is used to separate a gap between the upper end surface of the smart meter module 200 and the lower end surface of the top plate 430 .

[0063] In this embodiment: the fixing frame 610 is installed at the rear side of the bottom plate 410, and the outer cylinder 621 installed on the fixing frame 610 passes through the top plate 430 without contacting it. Figure 7 As shown, the outer cylinder 621 is filled with compressed gas, the valve seat 641 is closed by the valve stem 642, and the communication between the first chamber 625 and the third chamber 627 is blocked. At this time, the first chamber 625 and the second chamber 626 on both sides of the piston 624 are not connected. At this time, since the compressed air is difficult to be further compressed, the position of the piston 624 is fixed, and the position of the top plate 430 is fixed.

[0064] In the plurality of supporting frame mechanisms 400, all supporting forces are borne by the plurality of gas pressure rod assemblies 620, and the smart meter module 200 is not subjected to force and will not be pressed. Furthermore, an elastic metal sheet 210 is installed on the upper end of the smart meter module 200, so that a certain gap is left between the top plate 430 and the upper end of the smart meter module 200 to prevent the smart meter module 200 from being squeezed.

[0065] To control the automatic downward movement of the top plate 430, the valve stem 642 needs to be lifted so that the valve seat 641 is opened. After the first chamber 625 and the second chamber 626 are connected, since the air pressures at the two places are the same, but the force-bearing areas are different, the upper side of the piston 624 is the area of ​​the complete piston 624, and the lower side of the piston 624 is the area of ​​the piston 624 minus the area of ​​the piston rod 623. Therefore, the piston 624 is driven by the downward force to automatically move the top plate 430 downward. Until it contacts the elastic metal sheet 210 and squeezes the elastic metal sheet 210 to a certain extent, it cannot move further downward. Then the valve stem 642 is controlled to move downward and reclose the valve seat 641. The first spring 645 plays the role of supporting the valve stem 642 and resetting it.

[0066] Embodiment 3

[0067] In order to automatically trigger the operation of the gas pressure rod assembly 620 to move downward and then stop during the process of inserting the smart meter module 200 along the bottom plate 410, and considering that the smart meter module 200 may have different widths, embodiment 3 is proposed;

[0068] This embodiment is an improvement on the second embodiment. For details, please refer to Figure 3-Figure 10 The trigger assembly 640 includes a valve seat 641 disposed in the inner cylinder 622, and a valve stem 642 is disposed on the valve seat 641. The opening and closing of the channel between the first chamber 625 and the third chamber 627 is controlled by the lifting and lowering of the valve stem 642;

[0069] The fixing frame 610 is provided with a first sliding groove 643, in which a sliding rod 644 is slidably arranged, the sliding rod 644 is connected to the valve stem 642, and the sliding rod 644 is elastically connected to the outer cylinder 621 through a first spring 645;

[0070] The trigger assembly 640 further includes a driving assembly 646. When the smart meter module 200 slides along the bottom plate 410 from the front side to the rear side, the channel between the first chamber 625 and the third chamber 627 is controlled by the driving assembly 646 to be first opened and then closed.

[0071] The driving assembly 646 includes a base 6461 disposed on the bottom plate 410, a second slide groove 6462 is formed on the base 6461, a slider 6463 is slidably disposed in the second slide groove 6462, and the slider 6463 is elastically connected to the inner wall of the second slide groove 6462 via a second spring 6464;

[0072] The slider 6463 and the slide bar 644 are both provided with a first connection seat 6465, and the two first connection seats 6465 are connected in transmission via a first lever 6466;

[0073] The driving assembly 646 further includes a third slide groove 6467 disposed on the slider 6463, and a trigger rod 6468 is slidably disposed in the third slide groove 6467;

[0074] One end of the trigger rod 6468 is elastically connected to the inner wall of the third sliding groove 6467 through the third spring 6469 , and the other end of the trigger rod 6468 movably passes through the base 6461 and extends to the front side of the bottom plate 410 .

[0075] In this embodiment, the smart meter module 200 moves backwards to push the trigger rod 6468 to move backwards, and at this time, due to the support of the third spring 6469, the slider 6463 moves backwards together. The first connecting seat 6465 is located in the middle of the entire second slide slot 6462.

[0076] In the process of the slider 6463 moving backward and squeezing the second spring 6464, the first lever 6466 is firstly driven by the first lever 6466 and the two first connecting seats 6465. Fig. 9 The opposite tilt direction gradually moves to the vertical direction, and this process drives the slide bar 644 to rise, and then gradually moves from the vertical direction to the vertical direction. Fig. 9 The tilting direction in the middle causes the slide bar 644 to move downward.

[0077] Thus, the slide bar 644 rises first and then falls, and accordingly drives the valve stem 642 to rise first and then fall. Considering that the width of the smart meter module 200 may be different, a third slide groove 6467 and a third spring 6469 are provided. After the slide bar 6463 has moved back to the rear side of the second slide groove 6462, the smart meter module 200 has not been fully inserted. At this time, the smart meter module 200 can push the trigger rod 6468 to continue to move back.

[0078] Embodiment 4

[0079] In addition to placing the smart meter module 200, the general frame is also provided with a buckle structure to fasten the smart meter module 200 to a certain extent to prevent shaking. For this purpose, the fourth embodiment is proposed;

[0080] This embodiment is an improvement on the first embodiment. For details, please refer to Figure 2-Figure 5 The installation mechanism 300 also includes a snap mechanism 500, which includes two elastic snaps 510 symmetrically arranged in the middle of the smart meter module 200. Two fourth slide grooves 520 are symmetrically opened in the module box body 100. The two fourth slide grooves 520 are both slidably provided with snap seats 530, and the two elastic snaps 510 are movably snapped on the two snap seats 530 respectively.

[0081] In this embodiment, the two elastic buckles 510 on both sides of the smart meter module 200 are engaged with the two buckle seats 530 during the insertion process to fix the smart meter module 200.

[0082] Embodiment 5

[0083] Considering that the heights of the smart meter modules 200 are different, and for greater stability, the buckle is usually set in the middle of the smart meter module 200, so the height of the buckle also needs to be automatically adjusted, and for this purpose, embodiment 5 is proposed;

[0084] This embodiment is an improvement made on the basis of the fourth embodiment. For details, please refer to Figure 3-Figure 12 The mounting mechanism 300 further includes two second automatic adjustment mechanisms 700 symmetrically arranged on the bottom plate 410.

[0092] In this embodiment, the initial position of the buckle seat 530 is maintained in the middle of the bottom plate 410 and the top plate 430 , and is also maintained in the middle of the corresponding smart meter module 200 after automatic adjustment.

[0093] Specifically, when the top plate 430 automatically moves downward, the second connecting seat 724 and the third slide 726 are driven downward. During this process, the third slide 726 slides horizontally along the seventh slide groove 725. The third slide 726 drives the second lever 723 and the first rotating rod 722 to rotate a certain angle, driving the first slide 715, the lifting seat 713 and the second slide 716 to move upward.

[0094] The second slide 716 moves upward and drives the third lever 733 and the second rotating rod 732 to rotate, drives the fourth slide 736 and the third connecting seat 734 to move downward, and then drives the buckle seat 530 to move downward. The transmission ratio can be adjusted so that the distance between the first rotating rod 722 and the third slide 726 on the second lever 723 is twice the distance between the first rotating rod 722 and the first slide 715. On the third lever 733, the distance between the second rotating rod 732 and the second slide 716 is equal to the distance between the second rotating rod 732 and the fourth slide 736.

[0095] It should be supplemented that, due to the presence of the elastic metal sheet 210, the distance between the bottom plate 410 and the top plate 430 is slightly greater than the height of the smart meter module 200. The transmission ratio between the top plate 430 and the first slide seat 715 can be slightly greater than 2:1. Alternatively, the initial position of the buckle seat 530 can be fine-tuned while maintaining the transmission ratio of 2:1.

[0096] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0097] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
