[0009] The locking member controller is movably connected to the locking member, and when the locking member controller receives a release signal, drives the locking member to release from the fixing member and releases the guide fixing member;

[0012] When there is a gap between the bottom of the box and the support platform, if the detection sensor detects that the environmental signal is less than a preset threshold, the detection sensor stops sending a drive signal to the first electromagnetic component and / or the second electromagnetic component, and sends a locking signal to the locking component controller.

[0016] The output end of the detection sensor is connected to each telescopic controller. When the detection sensor sends a release signal to the locking member controller, the detection sensor sends a retraction signal to the telescopic controller to retract the fixing member into the interior of the support platform; and before the detection sensor sends a locking signal to the locking member controller, the detection sensor sends an extension signal to the telescopic controller to make the fixing member protrude from the surface of the support platform.

[0029] If the value of the environmental signal is greater than or equal to a preset threshold, the detection sensor sends a release signal to the locking component controller and sends a drive signal to the first electromagnetic component and / or the second electromagnetic component, so that the first electromagnetic component and the second electromagnetic component create a gap between the bottom of the box and the support platform under electromagnetic action.

[0030] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:

[0031] The electric control box provided in the embodiment of the present application can fix the mounting plate and the support plate of the box body by the locking part during normal use. When vibration is detected, the detection sensor can first loosen the locking part through the locking part controller when it detects that the value of the environmental signal is greater than or equal to the preset threshold value, and then control the first electromagnetic part and the second electromagnetic part to send a driving signal. The magnetic repulsion between the first electromagnetic part and the second electromagnetic part can make the box body float up. When the box body is suspended, the support tube can also protect the box body and prevent the box body from tipping over. This creates a gap between the box body and the support platform, preventing vibration from being transmitted from the support platform to the box body, thereby preventing vibration from damaging the components inside the box body.

[0042] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments.

Figure 5 A schematic diagram of the structure of the support platform provided in an embodiment of the present application. Figure 6 This is a schematic diagram of the device connections provided in the embodiments of the present application.

[0044] See also Figures 1-6As shown, an embodiment of the present application provides an electrical control box 100, which is installed on a support platform 200, and a first electromagnetic component 204 and a plurality of fixing components 202 are provided on the support platform 200. The electrical control box 100 includes: a support tube 205, a box body 101, a locking component 108, a locking component controller 302, a second electromagnetic component 106, a detection sensor 301 and a plurality of fixing guide components 105.

[0045] See also Figure 1 As shown, two doors 107 are provided on the box body 101, and an observation window 102 and an operating switch 103 can also be provided on the box door respectively, so that the operator can directly observe the status of the box components through the observation window 102 outside the box, and directly connect or disconnect the components inside the box through the operating switch 103.

[0046] See also Figure 2 and Figure 5 As shown, the support tube 205 is fixed to the support platform 200, and a support plate 201 is provided on the support platform. The support tube 205 is fixed around the support plate 201 and is perpendicular to the support plate 201. The outer width of the support tube 205 is greater than the outer size of the electric control box 100. In order to facilitate the fixing of the electric control box 100 in the support tube, see Figure 2 As shown, the first electromagnetic component 204 and all the fixing components 202 are arranged on the support platform 200 in the support cylinder 205, specifically on the support plate 201 on the support platform.

[0047] See also Figure 2 As shown, the support tube 205 is not shown in the figure. It can be seen that the projection position of the box body 101 is located within the projection position of the support tube 205, and a gap is set between the projection position of the outer wall of the box body 101 and the projection position of the inner wall of the support tube 205. In other words, when the box body 101 is properly placed, it can be in contact with the inner wall of the support tube 205 without compression. During installation, the box body can be firmly fixed to the support plate without contacting the support tube. When the box body floats, the support tube can protect the box body from the surrounding area. Even if the box body accidentally contacts the support tube, it will not cause the box body to fall.

[0048] See also Figure 1-Figure 5As shown, a mounting plate 104 is provided at the bottom of the box body 101, and a plurality of the fixing guides 105 are located on the periphery of the mounting plate 104 at the bottom of the box body 101. The fixing guides 105 in the figure can be four through holes at the four corners. In other embodiments, the number of through holes can also be 6 or 8, etc. Each of the fixing members 202 corresponds to the position of a fixing guide 105. During installation, each fixing member 202 passes through a corresponding fixing guide 105 and is fixed to the locking member 108. In the embodiment of the present application, the fixing member 202 can be a screw, and the fixing guide 105 can be a through hole. The inner diameter of the through hole of the fixing guide 105 is larger than the outer diameter of the screw, and it only plays a guiding role and does not limit or fix the fixing member. The locking member 108 can be a nut.

[0049] For specific installation, see Figure 2 As shown, when the box 101 is placed on the support plate 201, the fixing guide 105 thereon can pass through the fixing member 202. At this time, because the inner diameter of each through-hole in the mounting plate 104 is larger than the outer diameter of the screw of the fixing member 202, the box 101 can still rock left and right and is not fixed. The locking member can be fixed to each screw, and by tightening the nut of the locking member, the mounting plate 104 of the box 101 and the support plate 201 are fixed together. The outer diameter of the nut of the locking member is larger than the inner diameter of the through-hole in the fixing guide 105.

[0050] In other embodiments, the fixing member 202 may be a slide bar or a guide slot, the fixing guide 105 may be a through hole, the fixing member 202 may be provided with a plurality of horizontally arranged locking holes, and the locking member 108 may be a latch or a locking pin, the length of which is greater than the diameter of the through hole. In this way, after the fixing member 202 passes through the through hole of the fixing guide 105, the locking member 108 can be inserted into the locking hole of the slide bar or guide slot, preventing the fixing member 202 from falling out of the through hole.

[0051] The locking member controller 302 is movably connected to the locking member 108. When the locking member controller 302 receives a release signal, it drives the locking member 108 to release from the fixing member 202, thereby loosening the connection between the fixing guide member 105 and the locking member 108. In the embodiment of the present application, the locking member controller 302 can be a drive motor, and the screw of the drive motor is connected to the nut. When the drive motor rotates, the nut can be tightened or loosened. After the nut of the locking member is loosened, the locking member will not fall off the fixing member 202.

[0052] The detection sensor 301 is used to detect environmental signals. In an embodiment of the present application, the detection sensor 301 can be a vibration sensor for sensing environmental vibration signals. The output end of the detection sensor 301 is respectively connected to the locking member controller 302, the first electromagnetic member 204, and the second electromagnetic member 106. In a specific application, when the detection sensor 301 detects that the value of the environmental signal is greater than or equal to a preset threshold, a release signal is sent to the locking member controller 302, and a drive signal is sent to the first electromagnetic member 204 and / or the second electromagnetic member 106, so that the first electromagnetic member 204 and the second electromagnetic member 106 create a gap between the bottom of the box and the support platform under the electromagnetic action.

[0053] The electric control box provided in the embodiment of the present application can fix the mounting plate and the support plate of the box body by the locking part during normal use. When vibration is detected, the detection sensor can first loosen the locking part through the locking part controller when it detects that the value of the environmental signal is greater than or equal to the preset threshold value, and then control the first electromagnetic part and the second electromagnetic part to send a driving signal. The magnetic repulsion between the first electromagnetic part and the second electromagnetic part can make the box body 101 float up. When the box body is suspended, the support tube can also protect the box body and prevent the box body from tipping over. This creates a gap between the box body and the support platform, preventing vibration from being transmitted from the support platform to the box body, thereby preventing vibration from damaging the components inside the box body.

[0054] In one embodiment of the present application, upon receiving a locking signal, the locking member controller drives the locking member to be securely connected to the fixing member and lock the fixing guide member. The locking controller may be a drive motor. In this embodiment of the present application, four drive motors may be provided at each of the four corners. The rotating shaft of each motor is securely connected to a locking member (nut), and can drive the locking member to rotate on the fixing member (screw), thereby locking the fixing member and the fixing guide member.

[0055] In an embodiment of the present application, the driving motor can control the locking member in two ways, one is locking, and the other is releasing. Among them, when there is a gap between the bottom of the box body 101 and the support platform 200, that is, at this time, the magnetic forces between the first electromagnetic member and the second electromagnetic member repel each other, and the box body and the support platform are suspended by magnetic suspension. At this time, if the detection sensor detects that the environmental signal is less than the preset threshold, that is, when the environment is no longer vibrating, the detection sensor stops sending a drive signal to the first electromagnetic member and / or the second electromagnetic member. This means that the box body will no longer be magnetically suspended, but will fall and fall on the support plate 201 along the fixed guide. At this time, the detection sensor will also send a locking signal to the locking member controller, thereby locking the box body 101 and the support plate 201.

[0056] Therefore, the embodiment of the present application can achieve that when vibration is detected, the locking member can be loosened, and the box can be levitated by generating opposing magnetic forces between the first and second electromagnetic members. After the vibration disappears, the first and second electromagnetic members are deactivated, the magnetic levitation is stopped, and the locking member is tightened to re-lock the box to the support plate 201.

[0057] In the embodiment of the present application, the fixing member includes: a fixing screw or a fixing rod, and the fixing member may include four, and the four fixing members are respectively located on the periphery of the projection of the box body on the supporting platform.

[0058] The aforementioned fixing member is a screw. In another embodiment of the present application, the fixing member further comprises: a plurality of telescopic controllers, the plurality of telescopic controllers being fixed within the support platform, with each fixing member being connected to the telescopic shaft of one of the telescopic controllers. In other words, the fixing member itself is directly connected to the telescopic shaft of the telescopic controller.

[0059] With the above design, the fixing member can protrude from the surface of the support platform or retract into the interior of the support platform under the drive of the telescopic shaft of the telescopic controller. The movement of the fixing member can cause the fixing member to escape from or extend into the fixed guide member.

[0060] After the above-mentioned setting, in order to facilitate control, the output end of the detection sensor is connected to each telescopic controller. When the detection sensor sends a release signal to the locking member controller, the detection sensor sends a retraction signal to the telescopic controller to retract the fixing member into the interior of the support platform; and before the detection sensor sends a locking signal to the locking member controller, the detection sensor sends an extension signal to the telescopic controller to make the fixing member protrude from the surface of the support platform.

[0061] With this design, after detecting a vibration signal, the detection sensor sends a release signal to the locking member controller, which in turn sends a retraction signal to the telescopic controller. This causes the fixing member to retract along with the telescopic controller into or beneath the support platform. At this point, the fixing member disengages from the fixing guide. If the box needs to be suspended, the fixing member and the fixing guide will not interfere with the box.

[0062] Before the detection sensor sends a locking signal to the locking member controller, the detection sensor sends an extension signal to the telescopic controller to make the fixing member protrude from the surface of the support platform, and the fixing member passes through the fixing guide member, so that the locking member can lock the fixing member.

[0063] The embodiment of the present application provides a power supply box. When the box needs to be suspended, the fixing part can be retracted into the support platform to avoid the fixing part interfering with the stability of the box when it is suspended. When suspension is not required, the fixing part will extend and pass through the fixing guide part, making it convenient for the locking part to lock the fixing part.

[0064] like Figure 1 As shown, a peripheral mounting plate 104 is provided at the bottom of the box body 101, and the fixing guide 105 is a mounting hole passing through the mounting plate, or a mounting groove opening at the edge of the mounting plate (an open groove opening facing outward), and the area of ​​the mounting hole or the opening of the mounting groove is larger than the outer diameter of the fixing screw or the fixing rod.

[0065] like Figure 2 As shown, the top of the fixing member 202 is provided with a limited fixing structure, and the locking member is provided with a limited matching structure that cooperates with the limited structure. The limited matching structure can be connected to or released from the limited fixing structure. In the embodiment of the present application, the limited fixing structure can be a thread, and the corresponding limited matching structure can also be a thread. In other embodiments, the limited matching structure can be a plurality of horizontal through holes, and the corresponding limited matching structure can be a latch.

[0066] For the convenience of driving, the locking member controller is a driving motor, the locking member is connected to the driving shaft of the driving motor, and can be connected to or released from the limiting fixing structure under the drive of the driving shaft.

[0067] In other embodiments of the present application, the support tube can protect the box body from tipping over when the box body is suspended. However, during normal use, the support tube may affect the opening or closing of the box door. To this end, in the embodiment of the present application, the support tube includes: a tube body and a tube body lifting controller, the tube body lifting controller is disposed within the support platform, and the tube body is connected to the lifting rod of the tube body lifting controller.

[0068] The cylinder can protrude from the surface of the support platform or retract into the interior of the support platform under the drive of the lifting rod of the cylinder lifting controller; the initial state of the cylinder is to be located inside the support platform.

[0069] In a specific application, the output end of the detection sensor is connected to the cylinder lifting controller. When the detection sensor detects that the environmental signal is greater than or equal to a preset threshold, the detection sensor sends a lifting signal to the cylinder lifting controller to make the cylinder protrude from the surface of the support platform; and if the detection sensor detects that the environmental signal is less than the preset threshold, the detection sensor sends a descending signal to the cylinder lifting controller to make the cylinder descend into the surface of the support platform.

[0070] The electric control box provided in the embodiment of the present application has a support tube that can be hidden inside the support platform in the initial state (for example, when the support platform is installed on the ground, it is equivalent to the support tube being hidden underground). When vibration is detected, the support tube will support the platform to rise when a raising signal is received, and limit the box body around the four sides when the box body is suspended to prevent the box body from tipping over.

[0071] In the aforementioned embodiment, the support tube and the housing are in direct contact, which may cause friction or extrusion and damage the housing. To this end, in the embodiment of the present application, an annular third electromagnetic component may be provided on the inner wall of the support tube, and an annular fourth electromagnetic component may be provided on the outer wall of the housing corresponding to the position of the support tube. The third and fourth electromagnetic components cooperate to stabilize the housing on the support tube.

[0072] In the embodiment of the present application, only after the cylinder of the support cylinder rises into position in the air of the cylinder lifting controller, the third electromagnetic component and the fourth electromagnetic component will be energized and coordinated, so that the cylinder can keep the box body stable in the cylinder body through the repulsive magnetic force between the third electromagnetic component and the fourth electromagnetic component, and will not tip over.

[0073] In other embodiments of the present application, the detection sensor includes: a first vibration sensor, a second vibration sensor and a signal processor, wherein:

[0074] The first vibration sensor is installed on the box; the second vibration sensor is installed on the supporting platform;

[0075] The input end of the signal processor is connected to the first vibration sensor and the second vibration sensor respectively, and is used to calculate the difference between a first detection signal collected by the first vibration sensor and a second detection signal collected by the second vibration sensor; if the difference between the first detection signal and the second detection signal is greater than a preset threshold, the output end of the signal processor serves as the output end of the detection sensor, and outputs the average of the first detection signal and the second detection signal as the environmental signal.

[0076] By using two vibration sensors, it is possible to avoid false alarms from a single vibration sensor signal that could cause incorrect control of the box. One of the two vibration sensors can be installed on the box, and the other on the ground around the support platform. Thus, when the difference between the first and second detection signals exceeds a preset threshold, it indicates that significant shaking has occurred between the two, and vibration can be determined. When outputting, the average of the first and second detection signals can be used to avoid the problem of being unable to drive when the sensing signal of a single sensor is 0.

[0077] In other embodiments of the present application, a method for controlling an electric control box is further provided. The method is applied to the electric control box described in any of the aforementioned embodiments. In an initial state, each of the fixing members in the electric control box passes through a corresponding fixing guide and is fixed to the locking member. The method:

[0078] Detecting environmental signals using detection sensors;

[0079] If the value of the environmental signal is greater than or equal to a preset threshold, the detection sensor sends a release signal to the locking component controller and sends a drive signal to the first electromagnetic component and / or the second electromagnetic component, so that the first electromagnetic component and the second electromagnetic component create a gap between the bottom of the box and the support platform under electromagnetic action.

[0080] According to the method provided by the embodiment of the present application, during normal use, the locking member can fix the mounting plate and the support plate of the box body. When vibration is detected, the detection sensor can first loosen the locking member through the locking member controller when it detects that the value of the environmental signal is greater than or equal to the preset threshold value, and then control the first electromagnetic member and the second electromagnetic member to send a driving signal. The magnetic repulsion between the first electromagnetic member and the second electromagnetic member can make the box body 101 float up. When the box body is suspended, the support tube can also protect the box body and prevent the box body from tipping over. This creates a gap between the box body and the support platform, preventing the vibration from being transmitted from the support platform to the box body, thereby preventing the vibration from damaging the components inside the box body.
