It can control the scope of fault occurrence so that during maintenance work, the cause of the fault can be accurately and quickly found and normal power supply can be restored in the shortest time. It can also manage the power supply in segments and categories. When the line is under maintenance, there will be no situation where life is affected by large-scale power outages.
[0003] The distribution cabinet is equipped with fuses and air switches to prevent short circuits, which are used for measuring and protecting voltage, current, etc. During use, these devices need to be connected to the wiring harness in the distribution cabinet, and these devices will vibrate during use. The vibration will cause instability of the wiring harness connection joints. For this reason, existing distribution cabinets are generally equipped with buffering and energy-absorbing devices.

[0030] As described above, the energy absorption method of the power distribution cabinet with three-way energy absorption in space is as follows:
[0031] When the power control components are installed on the mounting frame, when the power control components themselves vibrate or external factors cause the distribution cabinet body to vibrate, the No. 1 spring can cooperate with the connecting component to pull the mounting frame, thereby buffering the vibration to absorb the energy generated by the vibration.
[0032] Compared with the prior art, the present invention has the following beneficial effects:
[0033] By setting the No. 1 spring and the connection assembly, when the mounting frame moves due to vibration, the mounting frame will move obliquely relative to the power distribution cabinet body, thereby making the displacement of the mounting frame in the direction of the vibration force smaller when the mounting frame vibrates, thereby improving the stability of the connection between the control components and the joints in the power distribution cabinet body, and avoiding the joints from breaking and loosening due to dragging;
[0034] The elastic trigger component is provided to make the installation process of the substrate more convenient and quick. When the rubber abutting piece acts on the substrate, on the one hand, it can exert pressure on the substrate, so that the substrate abuts against the lower abutting piece and the side abutting piece, thereby keeping the substrate parallel to the mounting frame and improving the stability of the substrate. On the other hand, the rubber abutting piece has a tendency to drive the substrate to fit toward the lower abutting piece, so that it has a certain positioning effect and improves the position accuracy of the substrate.
[0035] By setting the deflection assembly, when the sliding member is pulled to move, the deflection rod can perform a deflection action, so that the rubber contact piece can overlap with the substrate, which can avoid interference with the rubber contact piece during the process of placing the substrate. At the same time, the deflection rod is connected by the connecting bracket, which can drive the deflection rod to move relative to the mounting frame during the deflection of the deflection rod, thereby improving the stability of the multi-directional movement of the deflection rod;
[0036] By setting the pulling rod, follower frame and elastic locking structure, the locking shaft can be inserted into the locking groove during the process of disassembling the substrate, and the mounting frame can be locked to prevent the mounting frame from being displaced during the process of removing the substrate, thereby improving the stability of the mounting frame during the installation of the substrate and reducing the difficulty of operation. At the same time, after the substrate is installed, the locking shaft can be separated from the locking groove, so that after the substrate is installed, the mounting frame has the effect of elastic buffering and energy absorption, thereby improving the connection stability at the joint.

DETAILED DESCRIPTION

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.
[0048] See also Figure 1 to Figure 8 In an embodiment of the present invention, a three-way spatial energy absorption distribution cabinet includes: a distribution cabinet body 1, a No. 1 spring 3, a connection assembly, a loading mechanism, a follower frame 6 and a pulling plate 27, so that in the process of disassembling the substrate, the locking shaft 9 can be inserted into the locking groove 501 to achieve the locking of the mounting frame 2, so as to prevent the mounting frame 2 from being displaced in the process of preventing the substrate, improve the stability of the mounting frame 2 in the process of installing the substrate, and reduce the difficulty of operation. At the same time, after the substrate is installed, the locking shaft 9 can be separated from the locking groove 501, so that after the substrate is installed, the mounting frame 2 has the effect of elastic buffering and energy absorption, thereby improving the connection stability at the joint.
[0049] The details are as follows: a mounting frame 2 is provided in the power distribution cabinet body 1, and the mounting frame 2 is connected with power control components;
[0050] The No. 1 spring 3 is provided with multiple groups, and the No. 1 spring 3 is connected to the power distribution cabinet body 1 and the mounting frame 2;
[0051] The connecting assembly connects the power distribution cabinet body 1 and the mounting frame 2, a locking groove 501 is formed on the connecting assembly, and the connecting assembly includes a plurality of connecting seats 4 arranged between the power distribution cabinet body 1 and the mounting frame 2, and a spherical cavity is formed in the connecting seat 4;
[0052] The connecting assembly further comprises a connecting rod 5, each end of which is provided with a ball head adapted to the spherical cavity, and the ball head close to the side of the mounting frame 2 is provided with the locking groove 501;
[0053] In this embodiment, there are four groups of No. 1 springs 3, which are symmetrically arranged at both ends of the mounting frame 2. At the same time, there are four groups of connecting seats 4, two in each group, which are respectively installed on the mounting frame 2 and the distribution cabinet body 1. In the initial state, the four groups of No. 1 springs 3 are all in a stretched state, so that the four groups of No. 1 springs 3 have a pulling force on the mounting frame 2. At this time, considering that the mounting frame 2 itself has a certain gravity, the connecting rod 5 is in a downward tilted state, and when the power control components are installed on the mounting frame 2, the downward tilted state of the connecting rod 5 will be more obvious. Based on this, when the power control components themselves vibrate during operation or external factors cause the distribution cabinet body 1 to vibrate, the mounting frame 2 will move relative to the distribution cabinet body 1. For the convenience of understanding, a single vibration force is analyzed:
[0054] When the mounting frame 2 moves upward due to vibration, the two groups of No. 1 springs 3 at the lower part of the mounting frame 2 can pull the mounting frame 2, thereby reducing the displacement of the mounting frame 2 moving upward;
[0055] When the mounting frame 2 moves to the left due to vibration, the two groups of No. 1 springs 3 on the right side of the mounting frame 2 can pull the mounting frame 2, thereby reducing the displacement of the mounting frame 2 to the left;
[0056] When the mounting frame 2 moves forward due to vibration, the four groups of No. 1 springs 3 can all pull the mounting frame 2 to reduce the displacement of the mounting frame 2 moving forward. When the mounting frame 2 moves backward due to vibration, since the connecting rod 5 is in an inclined state, the connecting rod 5 will not provide hard support for the movement of the mounting frame 2, and the mounting frame 2 can also receive a better buffering effect.
[0057] It is worth noting that when the mounting frame 2 moves due to vibration, since it is connected to the distribution cabinet body 1 through the connecting seat 4 and the connecting rod 5, the mounting frame 2 does not move horizontally or vertically. Specifically, the mounting frame 2 will move obliquely relative to the distribution cabinet body 1, thereby enabling the displacement of the mounting frame 2 along the direction of the vibration force to be smaller when it vibrates, thereby improving the stability of the connection between the control components and the joints in the distribution cabinet body 1, and avoiding breakage and loosening of the joints due to dragging.
[0058] See also Figure 2 , Figure 3 , Figure 5~Figure 8 , the loading mechanism is arranged on the mounting frame 2, and the power control components can be detachably connected to the power distribution cabinet body 1 through the loading mechanism;
[0059] The loading mechanism includes: a side plate 13, an elastic trigger assembly, a deflection assembly, a lower abutment member 10, a stop plate 11 and a side abutment member 12, wherein an inclined guiding surface and an abutment position are formed inside the side abutment member 12, and when the substrate connected to the control electronic components is installed, the bottom is placed on the lower abutment member 10, and then when the substrate is flipped to be parallel to the mounting frame 2, the side abutment member 12 can guide the side of the substrate and align the left and right positions of the substrate until the substrate is attached to the abutment position on the side abutment member 12, at which time one end of the substrate abuts on the lower abutment member 10, and the upper part abuts on the abutment position on the side abutment member 12, while remaining parallel to the mounting frame 2.
[0060] Two groups are provided and symmetrically mounted on both sides of the mounting frame 2, and a rubber abutment sheet 21 is provided on the side plate 13;
[0061] The elastic trigger component is connected to the rubber contact piece 21, and the elastic trigger component can make the rubber contact piece 21 have a tendency to move toward the two ends of the side plate 13, and when the rubber contact piece 21 moves toward the end of the side plate 13, the elastic trigger component can drive the rubber contact piece 21 to move toward the control electric component;
[0062] The side plate 13 is provided with a slide groove 1301, in which a sliding member 14 is slidably installed, and the sliding member 14 is connected to the pulling plate 27;
[0063] The elastic trigger assembly includes a follower sleeve 15 mounted on the sliding member 14, a connecting bracket 16 is slidably mounted in the follower sleeve 15, a No. 3 spring 17 is sleeved on the connecting bracket 16, one end of the No. 3 spring 17 is connected to the end of the connecting bracket 16, and the other end is connected to the upper top wall of the follower sleeve 15;
[0064] The elastic trigger assembly further includes a guide structure disposed between the connecting bracket 16 and the side plate 13, the guide structure including a pulley 18 rotatably mounted on the connecting bracket 16 and a connecting plate 19 parallel to the side plate 13, a first inclined surface 1901 and a second inclined surface 1902 are formed on the connecting plate 19, and a protrusion is formed at the connection between the first inclined surface 1901 and the second inclined surface 1902;
[0065] When the pulley 18 moves toward the protrusion, the third spring 17 can be compressed.
[0066] In the initial state, the No. 3 spring 17 is in a compressed state. At this time, the pulley 18 is at the end of the No. 2 inclined surface 1902 away from the protrusion. At this time, pulling the sliding member 14 to move along the sliding groove 1301 can drive the follower sleeve 15 to move, and then the pulley 18 moves along the No. 2 inclined surface 1902 toward the protrusion. In this process, the pulley 18 will pull the connecting bracket 16 away from the mounting bracket 2. At the same time, the No. 3 spring 17 is further compressed to store potential energy. As the pulling progresses, when the pulley 18 moves over the protrusion and moves to the No. 1 inclined surface 1901, the No. 3 spring 17 will release the elastic potential energy, and the pulley 18 will actively move along the No. 1 inclined surface 1901. At the same time, as the pulley 18 moves, it will drive the rubber abutment sheet 21 to move toward the substrate through the connecting bracket 16, and exert a pressure on the substrate. Under the action of this pressure, the substrate can fit tightly with the lower abutment 10 and the abutment position, thereby realizing the rapid installation of the substrate.
[0067] Furthermore, when the rubber abutment sheet 21 abuts against the substrate, the pulley 18 does not move to the end of the No. 1 inclined surface 1901, so that in this state, the No. 3 spring 17 still has a tendency to release elastic potential energy, and acts on the rubber abutment sheet 21 through the connecting bracket 16, thereby generating the above-mentioned pressure, and according to this characteristic, when the substrate within a certain thickness range is placed between the lower abutment member 10 and the side abutment member 12, it can be well clamped.
[0068] It is worth noting that when the rubber abutment sheet 21 moves toward the substrate, it also has a state of moving toward the lower abutment member 10, so that in the process of the rubber abutment sheet 21 being deformed by fitting with the substrate, the rubber abutment sheet 21 can have a tendency to drive the substrate to move toward the lower abutment member 10 through friction, making the substrate and the lower abutment member 10 fit more closely, thereby having a certain positioning effect on the substrate.
[0069] Through the above-mentioned arrangement, the installation process of the substrate is made more convenient and quick. When the rubber abutment sheet 21 acts on the substrate, on the one hand, it can exert pressure on the substrate, so that the substrate abuts against the lower abutment member 10 and the side abutment member 12, thereby keeping the substrate parallel to the mounting frame 2 and improving the stability of the substrate. On the other hand, the rubber abutment sheet 21 has a tendency to drive the substrate to fit toward the lower abutment member 10, so that it has a certain positioning effect, thereby improving the position accuracy of the substrate.
[0070] See also Figure 6 , Figure 8 The deflection assembly is connected to the connecting bracket 16 and the rubber contact piece 21. The deflection assembly can drive the rubber contact piece 21 to deflect so that it overlaps or misaligns with the rubber contact piece 21. The deflection assembly includes a rotating shaft 23 rotatably connected to the sliding member 14. A coaxial gear 25 is provided at one end of the rotating shaft 23. The gear 25 is adapted to a rack plate 26 provided on the mounting frame 2.
[0071] The interior of the rotating shaft 23 is a hollow structure, and a telescopic shaft 22 is sleeved in the rotating shaft 23. A deflection rod 20 is provided at one end of the telescopic shaft 22 away from the rotating shaft 23. The deflection rod 20 is connected to the rubber contact piece 21, and the rotating shaft of the deflection rod 20 is rotatably connected to the connecting bracket 16.
[0072] A limit block 2301 is provided in the rotating shaft 23 , and the limit block 2301 is matched with the limit groove 2201 provided on the telescopic shaft 22 . An abutment groove 2302 is also formed on the rotating shaft 23 , and the limit plate 24 provided on the side plate 13 is matched with the abutment groove 2302 .
[0073] In the initial state, the No. 3 spring 17 is in a compressed state. At this time, the pulley 18 is at the end of the No. 2 inclined surface 1902 away from the protrusion. At this time, the deflection rod 20 is in a state parallel to the side of the substrate, and the rubber abutment sheet 21 is in a state of misalignment with the substrate. In this state, the rubber abutment sheet 21 can be prevented from interfering with the substrate during the installation of the substrate, thereby improving the portability of the substrate during installation. At the same time, the pulley 18 has a tendency to move along the No. 2 inclined surface 1902 away from the protrusion, so that the deflection rod 20 can remain parallel to the side of the substrate, thereby improving the stability of the rubber abutment sheet 21 in the initial state.
[0074] Furthermore, in the initial state, the gear 25 is in meshing with the rack plate 26. When the sliding member 14 is pulled downward to move, the pulley 18 will move along the second inclined surface 1902. At the same time, the gear 25 rotates in meshing with the rack plate 26, and drives the deflection rod 20 to deflect through the rotating shaft 23 and the telescopic shaft 22, so that the rubber abutment sheet 21 can overlap with the base plate. At the same time, the connecting bracket 16 will also drive the deflection rod 20 and the rubber abutment sheet 21 to move away from the mounting frame 2 until the pulley 18 moves to the first inclined surface 1901. 5 is separated from the rack plate 26, and the pulley 18 will actively move along the first inclined surface 1901. At this time, the connecting bracket 16 will drive the deflection rod 20 and the rubber contact piece 21 to move toward the substrate until the rubber contact piece 21 and the substrate bottom base are in contact. In this process, the rubber contact piece 21 can continue to drive the deflection rod 20 to deflect by friction with the substrate until the limiting plate 24 contacts the contact groove 2302. At this time, the deflection rod 20 remains perpendicular to the side of the substrate until the rubber contact piece 21 can be stationary relative to the substrate, thereby achieving the fixation of the substrate.
[0075] When the substrate is disassembled, pulling up the sliding member 14 can reverse the above-mentioned action. It should be noted here that a damping sleeve is provided on the rotating shaft of the rotating shaft 23 to prevent the deflection rod 20 from returning to a state parallel to the side of the substrate under the action of gravity after the sliding member 14 moves upward and the rubber abutment sheet 21 is separated from the substrate, thereby ensuring that the deflection rod 20 is in a state parallel to the side of the substrate in the initial state of each time the sliding member 14 is pulled down.
[0076] Through the above-mentioned arrangement, when the sliding member 14 is pulled to move, the deflection rod 20 can perform a deflection action, and the rubber abutment sheet 21 can overlap with the substrate, which can avoid interference with the rubber abutment sheet 21 during the placement of the substrate. At the same time, the deflection rod 20 is connected by connecting the bracket 16, which can drive the deflection rod 20 to move relative to the mounting frame 2 during the deflection of the deflection rod 20, thereby improving the stability of the multi-directional movement of the deflection rod 20.
[0077] See also Figure 3~Figure 5 The following frame 6 is formed with a sliding connection portion 601 that is slidably connected to the mounting frame 2, and the following frame 6 is provided with an elastic locking structure that is adapted to the locking groove 501, and the elastic locking structure includes a fixed sleeve 7 installed on the following frame 6, and a locking shaft 9 is slidably installed in the fixed sleeve 7, and the locking shaft 9 can penetrate the connecting seat 4 and be inserted into the locking groove 501, and the locking shaft 9 is connected to the No. 2 spring 8 provided in the fixed sleeve 7;
[0078] The side of the locking shaft 9 is provided with a limiting portion 901, and the limiting portion 901 is adapted to fit the through groove provided on the side of the fixing sleeve 7.
[0079] The limit axis 602 is installed on the follower frame 6;
[0080] The pulling plate 27 is connected to the sliding member 14 , and a hysteresis groove 2701 adapted to the limiting shaft 602 is formed on the pulling plate 27 . When the loading mechanism is actuated to separate the control component from the mounting frame 2 , the locking shaft 9 can be inserted into the locking groove 501 .
[0081] In the initial state, the pulley 18 is at the end of the second inclined surface 1902 away from the protrusion. At this time, the limit shaft 602 is in a state of abutting against the lower end of the lag groove 2701, so that the follower frame 6 is at the highest point of the stroke. At this time, the locking shaft 9 is in a state of penetrating the connecting seat 4 and inserted into one of the ball heads, so that the connecting rod 5 can be locked with the connecting seat 4. At this time, the mounting frame 2 is in a locked state, so that during the process of placing the substrate, the mounting frame 2 will not give way, thereby improving the stability of the mounting frame 2 during the installation of the substrate and reducing the difficulty of operation.
[0082] After placing the substrate, pull down the sliding member 14. At this time, the sliding member 14 will actively move downward along the length direction of the slide groove 1301 under the cooperation of the pulley 18 and the No. 1 inclined surface 1901, so as to drive the pulling plate 27 to move synchronously. When the sliding member 14 moves to the end of the stroke, the limit shaft 602 can abut against the upper end of the retardation groove 2701, and drive the follower frame 6 to move downward. At this time, the locking shaft 9 is pulled and separated from the locking groove 501. At this time, the locking relationship between the ball head and the connecting seat 4 is released, so that when the mounting frame 2 or the distribution cabinet body 1 vibrates, energy absorption is achieved through the buffering of the No. 1 spring 3 to ensure the connection stability of the joint.
[0083] When the base plate is disassembled, the sliding member 14 can be pulled up. At this time, the mounting frame 2 has a tendency to follow the movement of the sliding member 14. However, a stop plate 11 is provided on the upper part of the mounting frame 2, so that after the stop plate 11 abuts against the mounting frame 2, the sliding member 14 can move upward relative to the mounting frame 2. When the sliding member 14 moves to the upper end of the stroke, the rubber abutment sheet 21 can be misaligned with the base plate, and at the same time, the follower frame 6 moves upward and drives the fixed sleeve 7 to move upward. At this time, due to the weight of the base plate, the locking shaft 9 will not be inserted into the locking groove 501, but is in a state of abutment with the ball head. At this time, the No. 2 spring 8 is compressed, and when the base plate is removed, the mounting frame 2 will rise, and the ball head can move in the connecting seat 4, so that the locking shaft 9 can be inserted into the locking groove 501. At this time, the No. 2 spring 8 releases its elastic potential energy, so that the locking shaft 9 is inserted into the locking groove 501.
[0084] It should be noted that a damping layer is provided on the surface of the sliding connection portion 601 to prevent the locking shaft 9 from being separated from the locking groove 501 when the sliding member 14 is pulled down.
[0085] It should also be noted that the end of the locking shaft 9 is conical to facilitate its insertion into the locking groove 501. At the same time, the cross-section of the matching portion between the locking shaft 9 and the locking groove 501 is circular to ensure three-way locking.
[0086] Through the above-mentioned arrangement, during the process of disassembling the substrate, the locking shaft 9 can be inserted into the locking groove 501 to achieve the locking of the mounting frame 2, so as to prevent the mounting frame 2 from being displaced during the process of removing the substrate, thereby improving the stability of the mounting frame 2 during the installation of the substrate and reducing the difficulty of operation. At the same time, after the substrate is installed, the locking shaft 9 can be separated from the locking groove 501, so that after the substrate is installed, the mounting frame 2 has the effect of elastic buffering and energy absorption, thereby improving the connection stability at the joint.
[0087] As an embodiment of the present invention, an energy absorption method of a power distribution cabinet with three-way spatial energy absorption as described above is also proposed:
[0088] When the power control components are installed on the mounting frame 2, when the power control components themselves vibrate or external factors cause the distribution cabinet body 1 to vibrate, the No. 1 spring 3 can cooperate with the connecting assembly to pull the mounting frame 2, thereby buffering the vibration to absorb the energy generated by the vibration.
[0089] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
[0090] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
