Description

Technical Field

[0001] This application relates to the field of electronic device installation and protection technology, and in particular to a protective box and a Bluetooth-connected inverter control device. Background Technology

[0002] An inverter, also known as a power regulator or power conditioner, is an essential part of a photovoltaic system. The main function of a grid-connected photovoltaic inverter is to convert the direct current generated by solar panels into alternating current used by household appliances. All the electricity generated by solar panels must be processed by the inverter before it can be output.

[0003] In related technologies, inverter control equipment typically uses an SPWM processor to modulate, filter, and boost voltage to obtain a sinusoidal AC power supply with matching frequency and rated voltage for use by the system's end users.

[0004] However, in inverter control equipment in related technologies, the mounting base and protective compartment used to install the control box are prone to inaccurate installation alignment, which can cause the protective compartment to easily detach from the mounting base and fail to achieve the protective effect, resulting in easy damage to the control box. Utility Model Content

[0005] Based on this, a protection box and a Bluetooth-connected inverter control device are provided to address the issue of how to improve the protection effect.

[0006] On the one hand, this application provides a protective box, including:

[0007] Mounting base;

[0008] A protective chamber is connected to the mounting base, and the protective chamber and the mounting base enclose each other to form a mounting cavity. The side wall of the protective chamber is provided with a slot.

[0009] The magnetic attraction assembly includes a correspondingly arranged electromagnet and a magnet, one of which is disposed on the mounting base and the other is disposed on the protective compartment;

[0010] A snap-fit ​​mechanism is provided on the mounting base and is used to cooperate with the slot.

[0011] In one embodiment, the mounting base has a first contact surface and the protective chamber has a second contact surface. When the protective chamber is connected to the mounting base, the first contact surface abuts against the second contact surface. A guide groove is provided on the first contact surface, and the electromagnet is disposed in the guide groove. A guide block is provided on the second contact surface, and the guide block is connected to the magnet.

[0012] In one embodiment, the latching mechanism includes a first latching plate and a second latching plate. The protective compartment is provided with the latching slots at positions corresponding to the first latching plate and the second latching plate. The protective box also includes a triggering mechanism that can drive the first latching plate and the second latching plate to engage with the corresponding latching slots.

[0013] In one embodiment, the triggering mechanism includes a spring lock, a trigger button, a transmission component, a first pusher, and a second pusher. The spring lock has a pressing end and a moving end. The pressing end passes through the mounting base and is connected to the trigger button. The transmission component includes a first rod and a second rod connected vertically. The moving end is connected to the first rod. When the pressing end is pressed, the moving end drives the transmission component to move in the mounting base along a first direction. The two ends of the second rod are slidably connected to the first pusher and the second pusher, respectively. When the transmission component moves along the first direction, it drives the first pusher and the second pusher to move away from each other along a second direction. The first pusher and the second pusher respectively push the first locking plate and the second locking plate to cooperate with the corresponding locking slots. The second direction is perpendicular to the first direction.

[0014] In one embodiment, the first pusher abuts against the side of the first latching plate facing the second latching plate, and the second pusher abuts against the side of the second latching plate facing the first latching plate. The bottom wall of the mounting base is provided with a first guide groove, the extension direction of the first guide groove being parallel to the second direction, and used to guide the first pusher and the second pusher to move relative to the mounting base along the second direction.

[0015] In one embodiment, both the first pusher and the second pusher include a guide plate and a push plate connected to each other. The guide plate is set at an acute angle relative to the push plate, and the guide plate is slidably connected to the end of the second rod. The push plate of the first pusher abuts against the first snap-fit ​​plate along the second direction, and the push plate of the second pusher abuts against the second snap-fit ​​plate along the second direction.

[0016] In one embodiment, the protective box further includes a buffer mechanism. Both the protective compartment and the mounting base are provided with the buffer mechanism. The buffer mechanism includes a first buffer and a second buffer. The first buffer includes a first plate, a second plate, a first damper, and a first spring. The two ends of the first damper are respectively fixedly connected to the first plate and the second plate. The first spring is sleeved on the outside of the first damper, and the two ends of the first spring elastically abut against the first plate and the second plate and are connected. The first plate is connected to the second buffer.

[0017] In one embodiment, the second buffer includes a buffer seat and a shock absorber. The buffer seat is in the shape of an open box and includes a connecting plate and four side plates arranged around the connecting plate. The shock absorber is provided on the inner wall of each of the four side plates.

[0018] In one embodiment, the shock absorber includes a second spring, a second damper, and a protective plate. The protective plate is connected to the side plate on the corresponding side of the buffer seat via the second damper. The second spring is correspondingly sleeved on the second damper, and its two ends elastically abut against the protective plate and the side plate, respectively. And / or, the connecting plate is provided with a plurality of heat dissipation holes.

[0019] On the other hand, this application provides an inverter control device based on Bluetooth interconnection, including a control box and a protection box as described above. The control box is installed in the mounting cavity, and at least one side wall of the protection box has multiple heat dissipation vents. The control box includes a housing and a cooling fan and a circuit board installed in the housing. The circuit board is provided with a microprocessor, an access unit, a power supply unit, and a Bluetooth unit. The access unit, the power supply unit, and the Bluetooth unit are all electrically connected to the microprocessor. The microprocessor is used to control the power supply unit to supply power to the cooling fan and the electromagnet according to the instructions received by the Bluetooth unit.

[0020] The aforementioned protective box and Bluetooth-connected inverter control device utilize the electromagnet's attraction to the magnet when energized to achieve the installation alignment between the protective chamber and the mounting base, improving the accuracy of the assembly position of the protective chamber relative to the mounting base. Furthermore, a snap-fit ​​mechanism is used to fix the protective chamber and the mounting base together, enhancing the assembly stability between them and preventing any misalignment of the protective chamber relative to the mounting base. This ensures that the mounting cavity enclosed by the protective chamber and the mounting base provides a safe and reliable installation environment. Attached Figure Description

[0036] Combination Figure 1 and Figure 2 As shown, one embodiment of this application provides an inverter control device based on Bluetooth interconnection, including a protection box 10 and a control box (not shown).

[0037] The protective enclosure 10 includes a mounting base 11 and a protective chamber 12. The protective chamber 12 is connected to the mounting base 11, and the two enclose each other to form a mounting cavity, within which the control box is housed. It should be noted that the mounting cavity enclosed by the protective chamber 12 and the mounting base 11 is not limited to mounting the control box; it can also be used to mount other electronic devices. In other words, the protective enclosure 10 can also provide an installation environment for other electronic devices, thereby providing protection for them.

[0038] Combination Figures 3 to 5 As shown, in some embodiments, the protective case 10 includes a snap-fit ​​mechanism 14 and a magnetic assembly 13. The snap-fit ​​mechanism 14 is used to snap-fit ​​the mounting base 11 to the protective compartment 12.

[0039] The surfaces of the mounting base 11 and the protective chamber 12 that contact each other are a first contact surface 11a and a second contact surface 12b, respectively. Specifically, the first contact surface 11a is the surface of the mounting base 11 facing the protective chamber 12 and is used to mate with the protective chamber 12. Correspondingly, the second contact surface 12b is the surface of the protective chamber 12 facing the mounting base 11 and is used to mate with the mounting base 11. In this embodiment, when the protective chamber 12 is connected to the mounting base 11, the first contact surface 11a and the second contact surface 12b abut against each other.

[0040] The magnetic assembly 13 includes an electromagnet 131 and a magnet 132, one of which is located on the mounting base 11 and the other on the protective chamber 12. When the electromagnet 131 is energized, it attracts the magnet 132 to achieve the installation alignment between the protective chamber 12 and the mounting base 11, improving the accuracy of the assembly position of the protective chamber 12 relative to the mounting base 11. This ensures a stable connection between the protective chamber 12 and the mounting base 11, and the mounting cavity enclosed by the protective chamber 12 and the mounting base 11 provides a safe and reliable installation environment for the control box, thereby enhancing the protection effect of the control box.

[0041] In some embodiments, a guide groove 11b is provided on the first contact surface 11a, and an electromagnet 131 is disposed within the guide groove 11b; a guide block 12c is provided on the second contact surface 12b, and a magnet 132 is connected to the guide block 12c. In this embodiment, the guide groove 11b and the guide block 12c are adapted to each other so that the cooperation between the guide groove 11b and the guide block 12c can provide a positioning function when the mounting base 11 and the protective chamber 12 are assembled. Furthermore, the magnetic attraction between the electromagnet 131 and the magnet 132 will enhance the assembly stability between the protective chamber 12 and the mounting base 11 after the mounting base 11 and the protective chamber 12 are installed in place, so as to prevent the protective chamber 12 from being misaligned relative to the mounting base 11.

[0042] After the protective chamber 12 and the mounting base 11 are pre-positioned using the magnetic suction component 13, it is convenient to fix the protective chamber 12 and the mounting base 11 using the snap-fit ​​mechanism 14.

[0043] The latching mechanism 14 is mounted on the mounting base 11, and the side wall of the protective compartment 12 is provided with a corresponding latching groove 12a (see reference). Figure 1 As shown), the slot 12a is used to cooperate with the buckling mechanism 14 so that the protective chamber 12 is buckled and connected to the mounting base 11.

[0044] The latching mechanism 14 includes a first latching plate 141 and a second latching plate 142. The protective compartment 12 is provided with a latching groove 12a at the position corresponding to the first latching plate 141 and the second latching plate 142, so that the latching groove 12a can cooperate with the corresponding first latching plate 141 and the second latching plate 142 to connect the protective compartment 12 to the mounting base 11.

[0045] In some embodiments, the first snap-fit ​​plate 141 and the second snap-fit ​​plate 142 are respectively located on both sides of the corresponding control box in the mounting base 11. That is, after the control box is installed in the mounting base 11, the first snap-fit ​​plate 141 and the second snap-fit ​​plate 142 are respectively located on both sides of the control box.

[0046] In some embodiments, both the first snap-fit ​​plate 141 and the second snap-fit ​​plate 142 are slidably engaged with the mounting base 11, and both the first snap-fit ​​plate 141 and the second snap-fit ​​plate 142 can slide relative to the mounting base 11 to a position corresponding to the snap-fit ​​groove 12a on the protective compartment 12. The sliding engagement between the first snap-fit ​​plate 141 and the mounting base 11, and between the second snap-fit ​​plate 142 and the mounting base 11, can be achieved via slide rails. In some embodiments, the bottom wall of the mounting base 11 is provided with a sliding groove, and the first snap-fit ​​plate 141 and the second snap-fit ​​plate 142 are respectively slidably engaged with the sliding groove. It should be noted that there can be one sliding groove, in which case the first snap-fit ​​plate 141 and the second snap-fit ​​plate 142 are slidably engaged with the same sliding groove, thus reducing the number of grooves required for the mounting base 11. Alternatively, there can be two sliding grooves, with the first snap-fit ​​plate 141 and the second snap-fit ​​plate 142 each achieving a sliding engagement with the mounting base 11 through one of the sliding grooves.

[0047] In some embodiments, the first snap-fit ​​plate 141 and the second snap-fit ​​plate 142 are both fixed to the mounting base 11, and the first snap-fit ​​plate 141 and the second snap-fit ​​plate 142 can move in opposite directions when compressed.

[0048] Combination Figures 5 to 7 As shown, the protective housing 10 also includes a triggering mechanism 15. The triggering mechanism 15 is used to operate the latching mechanism 14, so that the latching mechanism 14 locks or releases the engagement between the protective compartment 12 and the mounting base 11.

[0049] In some embodiments, the triggering mechanism 15 can drive the first card plate 141 and the second card plate 142 to engage with the corresponding card slot 12a.

[0050] The triggering mechanism 15 is disposed on the bottom wall of the mounting base 11. The triggering mechanism 15 includes a spring lock 151, a trigger button 152, a transmission component 153, a first pusher 154, and a second pusher 155. The spring lock 151 is fixed to the bottom of the mounting base 11 and can be a push-pull structure. The spring lock 151 has a pressing end and a moving end. The pressing end of the spring lock 151 passes through the mounting base 11 and is connected to the trigger button 152. The transmission component 153 includes a first rod 1531 and a second rod 1532 that are vertically connected. The moving end of the spring lock 151 is connected to the first rod 1531 of the transmission component 153 so that when the pressing end of the spring lock 151 is pressed, the moving end of the spring lock 151 drives the transmission component 153 to move within the mounting base 11 in a first direction (this first direction can be understood as the direction of movement of the pressing end of the spring lock 151 when pressed).

[0051] The two ends of the second rod 1532 of the transmission member 153 are slidably connected to the first pusher 154 and the second pusher 155, respectively. Driven by the moving end of the spring lock 151, when the transmission member 153 moves along the first direction, it drives the first pusher 154 and the second pusher 155 to move away from each other along the second direction, which is perpendicular to the first direction. In this embodiment, the length direction of the first rod 1531 is parallel to the first direction, and the length direction of the second rod 1532 is parallel to the second direction.

[0052] The first latching plate 141 and the second latching plate 142 are disposed opposite each other in a second direction. The first pushing member 154 abuts against the side of the first latching plate 141 facing the second latching plate 142, and the second pushing member 155 abuts against the side of the second latching plate 142 facing the first latching plate 141. Thus, when the transmission member 153 drives the first pushing member 154 and the second pushing member 155 away from each other in the second direction, the first pushing member 154 applies a pushing force to the first latching plate 141, causing the latching end of the first latching plate 141 to move away from the second latching plate 142, so that the latching end of the first latching plate 141 engages with the corresponding latching groove 12a on the side wall of the protective chamber 12; correspondingly, the second pushing member 155 applies a pushing force to the second latching plate 142, causing the latching end of the second latching plate 142 to move away from the second latching plate 142, so that the latching end of the second latching plate 142 engages with the corresponding latching groove 12a on the side wall of the protective chamber 12. In this way, the first snap-fit ​​plate 141 and the second snap-fit ​​plate 142 respectively cooperate with the corresponding snap-fit ​​grooves 12a on the side wall of the protective chamber 12 to fix the protective chamber 12 to the mounting base 11.

[0053] The bottom wall of the mounting base 11 is provided with a first guide groove 11c. The extension direction of the first guide groove 11c is parallel to the second direction, and it is used to guide the first pusher 154 and the second pusher 155 to move relative to the mounting base 11 along the second direction. The number of first guide grooves 11c can be one, or two or more can be provided to improve the movement stability of the first pusher 154 and the second pusher 155.

[0054] In some embodiments, both the first pusher 154 and the second pusher 155 include a guide plate D and a push plate T connected to each other. The guide plate D is set at an acute angle relative to the push plate T, and the guide plate D is slidably connected to the end of the second rod 1532. For example, the guide plate D is provided with a second guide groove DC, and the end of the second rod 1532 is slidably engaged with the second guide groove DC. The push plate T of the first pusher 154 abuts against the first locking plate 141 along the second direction, and the push plate T of the second pusher 155 abuts against the second locking plate 142 along the second direction.

[0055] Because the guide plate D and the push plate T are set at an acute angle, the guide plate D in the first pusher 154 and the second pusher 155 are both tilted outward in the second direction (i.e., away from the center of the second rod 1532) relative to the corresponding push plate T. Thus, when the transmission member 153 moves in the first direction, the second rod 1532 of the transmission member 153 slides along the second guide groove DC on the guide plate D in the first pusher 154 and the second pusher 155, causing the first pusher 154 and the second pusher 155 to move away from each other in the second direction. As a result, the push plate T in the first pusher 154 and the second pusher 155 will respectively push the first locking plate 141 and the second locking plate 142 to deform outward, so that the locking ends of the first locking plate 141 and the second locking plate 142 cooperate with the corresponding locking groove 12a to lock the assembly position between the protective chamber 12 and the mounting base 11, so that the protective chamber 12 cannot be disengaged from the mounting base 11.

[0056] Understandably, during the pressing process of the spring lock 151, the first rod 1531 will alternately drive the second rod 1532 to move to different positions along the first direction. When the second rod 1532 is in different positions in the first direction, the first pusher 154 and the second pusher 155 will be at different relative distances to each other due to their sliding engagement with the two ends of the second rod 1532, which in turn will result in different squeezing forces on the first locking plate 141 and the second locking plate 142. Based on this, by pressing the spring lock 151, the second rod 1532 is engaged with the corresponding slot 12a via the first locking plate 141 and the second locking plate 142. When the spring lock 151 is pressed again, the second rod 1532 moves back to the initial position along the first direction, thereby releasing the pressure of the first pusher 154 and the second pusher 155 on the first locking plate 141 and the second locking plate 142 or reducing the pressure force. Then, the first locking plate 141 and the second locking plate 142 are respectively removed from the corresponding slot 12a, thereby releasing the lock between the protective chamber 12 and the mounting base 11. At this time, the protective chamber 12 can be easily removed from the mounting base 11 to facilitate the maintenance of the electronic device in the mounting cavity.

[0057] In some implementations, a protective shell is provided on the mounting base 11 at the position corresponding to the trigger button 152 to prevent workers from accidentally touching it.

[0058] A buffer structure can also be added to the mounting structure of electronic devices in the mounting cavity to further enhance the protection of electronic devices.

[0059] For ease of understanding, the following description uses an electronic device installed in the mounting cavity as an example of a control box, but it does not imply that the protection box 10 of this application is limited to installing and protecting the control box.

[0060] In some implementations, combined Figure 3 and Figure 5 As shown, the protective enclosure 10 also includes a buffer mechanism 16. For example, buffer mechanisms 16 are provided between the protective compartment 12 and the control box, and between the mounting base 11 and the control box. The buffer mechanism 16 reduces the probability of the control box impacting the mounting base 11 or the protective compartment 12 by buffering the control box, thereby improving the protection effect on the inverter.

[0061] For ease of description, the buffer mechanism 16 located between the mounting base 11 and the control box is referred to as the "first buffer mechanism", and the buffer mechanism 16 located between the protective compartment 12 and the control box is referred to as the "second buffer mechanism".

[0062] In some embodiments, a first buffer mechanism is fixed to the side of the mounting base 11 facing the protective chamber 12 and is used to support the bottom of the control box. A second buffer mechanism is fixed to the side of the protective chamber 12 facing the mounting base 11 and is used to connect to the top of the control box. It should be noted that the bottom and top of the control box refer to the spatial position of the control box placed in the mounting cavity when the protective chamber 12 is arranged vertically above the mounting base 11. In this case, the end of the control box closest to the mounting base 11 is the bottom of the control box, and correspondingly, the other end of the control box is the top of the control box.

[0063] The first and second buffer mechanisms can adopt the same structure, thereby reducing the types of parts and improving the efficiency of standardized assembly.

[0064] In some embodiments, the buffer mechanism 16 includes a first buffer 161 and a second buffer 162. The first buffer 161 includes a first plate 1611, a second plate 1612, a first damper, and a first spring 1613. The two ends of the first damper are fixedly connected to the first plate 1611 and the second plate 1612, respectively. The first spring 1613 is sleeved outside the first damper, and its two ends elastically abut against the first plate 1611 and the second plate 1612. The first plate 1611 is connected to the second buffer 162, and the second buffer 162 is connected to the control box. Thus, by utilizing the first damper and the first spring 1613 between the first plate 1611 and the second plate 1612, the second buffer 162 can float relative to the second plate 1612, thereby achieving a buffering effect on the control box.

[0065] It should be noted that when both the first and second buffer mechanisms adopt the structure of the aforementioned buffer mechanism 16, the second buffer element 162 in the first and second buffer mechanisms is connected to the bottom and top of the control box, respectively. Specifically, the second plate in the first buffer mechanism is connected to the base, and the second buffer element 162 in the first buffer mechanism is connected to the bottom of the control box; the second plate in the second buffer mechanism is connected to the protective compartment 12, and the second buffer element 162 in the second buffer mechanism is connected to the top of the control box. Thus, by utilizing the first buffer element 161 of both the first and second buffer mechanisms, a good buffering effect can be achieved on the control box in the vertical direction.

[0066] The second buffer 162 provides a buffering effect for the control box in the horizontal direction. For example, the second buffer 162 includes a buffer seat 1621 and shock absorbers 1622. The buffer seat 1621 is an open box shape, including a connecting plate 16211 and four side plates 16212 arranged around the connecting plate 16211. Each of the four side plates 16212 has a shock absorber 1622 on its inner wall. Thus, when the control box is placed on the buffer seat 1621, the shock absorbers 1622 on the four side plates 16212 can provide a shock absorption effect for the control box in all directions on the horizontal plane. Thus, in the first and second buffer mechanisms, the combination of the first buffer 161 and the second buffer 162 can achieve shock absorption and buffering effects on the control box in the vertical direction and in the horizontal plane perpendicular to the vertical direction, thereby improving the protection effect of the control box and making the control box less susceptible to damage from impacts, which helps to improve the reliability and service life of the inverter control equipment based on Bluetooth interconnection.

[0067] In some embodiments, the shock absorber 1622 includes two second springs 16221, two second dampers, and a protective plate 16222. The protective plate 16222 is connected to the corresponding side plate 16212 on the buffer seat 1621 via the two second dampers. The two second springs 16221 are correspondingly sleeved on the two second dampers, and their ends elastically abut against the protective plate 16222 and the side plate 16212, respectively. Thus, the shock absorber 1622 can provide a buffering effect on the control box on the side corresponding to the side plate 16212. It is understood that the shock absorber 1622 installed on the side plates 16212 on other sides of the buffer seat 1621 can refer to the above-described configuration. Further details are omitted here.

[0068] Furthermore, the specific number of the second spring 16221 and the second damper can be configured according to actual needs and is not limited here. For example, in some embodiments, the number of second springs 16221 in the shock absorber 1622 can be two or more, and the number of second dampers is equal to the number of second springs 16221, so that the second springs 16221 can be fitted onto the second dampers one by one.

[0069] Understandably, since the number of second springs 16221 and second dampers provided in the shock absorber 1622 is two or more, so as to arrange the protective plate 16222 and the corresponding side plate 16212 in parallel, and to prevent the protective plate from tilting to one side relative to the side plate 16212, the shock absorber 1622 can improve the stability of buffering the control box that abuts against the protective plate 16222.

[0070] Furthermore, in an embodiment where the shock absorber 1622 includes two second springs 16221 and two second dampers, one end of each second damper can be connected to both ends of the protective plate 16222, and the other end can be fixedly connected to the inner wall of the buffer seat 1621. This improves the connection stability of the second dampers and the second springs 16221 between the protective plate 16222 and the inner wall of the buffer seat 1621.

[0071] It should be noted that, for the first buffer mechanism, the connecting plate 16211 of the buffer seat 1621 is connected to the bottom of the control box, and the four side plates 16212 of the buffer seat 1621 surround the periphery of the corresponding bottom position of the buffer seat 1621. For the second buffer mechanism, the connecting plate 16211 of the buffer seat 1621 is connected to the top of the control box, and the four side plates 16212 of the buffer seat 1621 surround the periphery of the corresponding top position of the buffer seat 1621.

[0072] Furthermore, the protective plate 16222 is provided with anti-slip rubber on the side that contacts the control box, thereby further improving the installation stability of the control box in the buffer seat 1621 and reducing the probability of the control box sliding relative to the buffer seat 1621 and being impacted.

[0073] The edge of the protective plate 16222 away from the connecting plate 16211 has an inner chamfer to facilitate the insertion of the control box into the space enclosed by the protective plates 16222 on each corresponding side plate 16212. The inner chamfer refers to the chamfer provided on the inner side of the protective plate 16222 (i.e., the side corresponding to the control box). This inner chamfer can be a rounded corner, thus providing a more rounded arc, which facilitates the smooth insertion of the control box into the space enclosed by the protective plates 16222 on each corresponding side plate 16212, reducing the chance of the outer wall of the control box being scratched.

[0074] In the buffer seat 1621 of the first buffer mechanism, the connecting plate 16211 is provided with multiple heat dissipation holes 16211a to facilitate heat dissipation of the control box. The number and shape of the heat dissipation holes 16211a are not limited here. In some embodiments, in the buffer seat 1621 of the second buffer mechanism, the connecting plate 16211 is provided with multiple heat dissipation holes 16211a to meet the heat dissipation needs of the top of the control box.

[0075] The protective chamber 12 has multiple heat dissipation vents 12d on at least one side wall. The control box includes a housing and a cooling fan installed inside the housing. The cooling fan drives airflow to dissipate heat through the heat dissipation vents 12d.

[0076] It should be noted that the installation location of the cooling fan can be varied, as long as the cooling fan can drive airflow through the heat dissipation port 12d to achieve heat dissipation. For example, in some embodiments, a heat dissipation hole 16211a is provided on one side of the protective chamber 12, and a cooling fan is provided on the opposite side.

[0077] In some embodiments, the control box also includes a circuit board mounted inside the box, which is used to control the circuitry of structures inside the box, such as cooling fans. The circuit board can be located either inside the mounting base 11 or inside the protective compartment 12. The mounting location of the circuit board is not limited here.

[0078] The circuit board houses a microprocessor, an access unit, a power supply unit, and a Bluetooth unit. All three units are electrically connected to the microprocessor. The power supply unit provides power to the access unit, Bluetooth unit, cooling fan, and electromagnet 131, among other components.

[0079] The microprocessor controls the power supply unit to supply power to the cooling fan and electromagnet 131 according to the instructions received from the Bluetooth unit, thereby controlling the start and stop of the cooling fan and the installation of the auxiliary mounting base 11 and protective chamber 12 of the electromagnet 131. For example, in some embodiments, a temperature sensor is provided on the inner wall of the protective chamber 12, and both the access unit and the power supply unit are electrically connected to the temperature sensor. The access unit is used to transmit the temperature data from the temperature sensor to the microprocessor; the microprocessor sends corresponding instructions to the power supply unit to control the start and stop of the cooling fan.

[0080] It should be noted that the control box, as a control device, can meet the need to control the controlled object. For example, in some implementations, as a key component of the inverter control equipment, the control box can control the inverter. Since the control box's circuit board is equipped with a Bluetooth unit, it can use the Bluetooth unit to transmit and receive signals, thus meeting the requirement for Bluetooth interconnection with the inverter.

[0081] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0082] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
