[0051] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0052] like Figures 1 to 4 As shown, an embodiment of the present invention provides a control cabinet, which includes a cabinet body 10, an electrical component 20, a mounting shell 30 and a first fan 40. The cabinet body 10 has a protective cavity 11 and a mounting port communicating with the protective cavity 11, the mounting port is located on the side plate 12 of the cabinet body 10, and the electrical component 20 is installed in the protective cavity 11. The mounting shell 30 is installed in the protective cavity 11 and connected to the side plate 12. The mounting shell 30 has a first communication port 31, a second communication port 32 and a mounting cavity communicating with the first communication port 31 and the second communication port 32. The second communication port 32 is arranged opposite to the mounting port. The mounting shell 30 is arranged around at least part of the mounting port. The first communication port 31 is located at the top of the mounting shell 30 and communicates with the protective cavity 11. The first fan 40 is rotatably arranged in the mounting cavity.

[0053] By adopting the control cabinet provided in this embodiment, the control cabinet can effectively guide the external cold air to enter and circulate, so as to directly dissipate the heat of the electrical components 20, thereby reducing the operating temperature of the electrical components 20. In addition, since the first connecting port 31 is located at the top of the installation shell 30, and the installation port is located at the side of the installation shell 30, the installation shell 30 encloses a separate installation cavity, which can facilitate the effective spatial isolation of the installation cavity and the protective cavity 11. Since the first connecting port 31 is located at the top of the installation shell 30, even if there is water or other debris in the installation cavity, it will not easily enter the protective cavity 11 through the installation cavity, thereby facilitating the effective isolation of the installation cavity and the protective cavity 11, avoiding the influence of foreign substances on the electrical components 20 in the protective cavity 11, so as to effectively protect the electrical components 20 in the protective cavity 11. In this way, the single-layer design of the control cabinet can also be realized, reducing the overall volume of the control cabinet.

[0054] In this embodiment, the control cabinet further includes a mounting plate 50, at least part of which is attached to the side plate 12 and blocked at the second connecting port 32, and a connecting portion 51 connected to the second connecting port 32 is provided on the mounting plate 50, and the first fan 40 is installed on the mounting plate 50, and the first fan 40 is spaced apart from the mounting housing 30, and the air outlet of the first fan 40 is arranged opposite to the connecting portion 51. Among them, the connecting portion 51 includes a central hole 511 and a plurality of annular hole groups 512, and the plurality of annular hole groups 512 are sequentially spaced along the radial extension direction of the central hole 511 at the periphery of the central hole 511. With such a structural arrangement, the size of the connecting area can be reduced as much as possible while ensuring that the first fan 40 is connected to the outside world, so as to reduce the entry of external impurities into the protective cavity 11 as much as possible, thereby facilitating better protection of the protective cavity 11.

[0055] Specifically, the mounting plate 50 may be welded to the side plate 12 .

[0056] Specifically, the installation plate 50 is provided with a drain outlet, which is located on one side of the installation plate 50 near the bottom of the installation cavity; the control cabinet also includes a plugging member 100, the shape of which matches the shape of the drain outlet, and the plugging member 100 is detachably arranged at the drain outlet. With such a structural arrangement, even when external water or impurities enter the installation cavity, the water or impurities in the installation cavity can be effectively discharged through the drain outlet, thereby better preventing external water or impurities from entering the protective cavity 11 through the installation cavity.

[0057] Specifically, the blocking member 100 may be a rubber plug.

[0058] Specifically, the installation shell 30 includes a bottom shell 33 and a side shell 34, and the bottom shell 33 is connected to the side plate 12. The side shell 34 is connected to the bottom shell 33 and surrounds at least the periphery of the bottom shell 33, and the two ends of the side shell 34 are respectively attached to the parts of the side plate 12 located on both sides of the installation opening, and the side of the side shell 34 away from the bottom shell 33 and the side plate 12 form a first communication opening 31. In this way, it is convenient to better form a relatively isolated installation cavity and protection cavity 11, prevent the material in the installation cavity from entering the protection cavity 11, and thus better protect the protection cavity 11.

[0059] In this embodiment, the control cabinet further includes a dust cover 60 and a dustproof member 70. The dust cover 60 is installed at the first connecting port 31. The dust cover 60 blocks the first connecting port 31. The dust cover 60 is provided with a dustproof port 61. The dustproof member 70 is installed on the dust cover 60, and the dustproof member 70 is arranged opposite to the dustproof port 61. In this way, the protective cavity 11 can be better protected to prevent foreign debris and impurities from entering the protective cavity 11.

[0060] Specifically, the dustproof member 70 may be dustproof cotton.

[0061] Specifically, the dust cover plate 60 includes a first plate body 62 and a second plate body 63 connected to each other, and the first plate body 62 and the second plate body 63 are both provided with a dustproof port 61. At least a portion of the first plate body 62 and the second plate body 63 are spaced apart to enclose a mounting cavity adapted to the dustproof member 70, and the dustproof member 70 is detachably disposed in the mounting cavity. With such a structural arrangement, the removal and installation of the dustproof member 70 can be facilitated.

[0062] In this embodiment, the control cabinet further includes a first temperature detection member 80 and a control member, and the first temperature detection member 80 is arranged in the protective cavity 11. The first temperature detection member 80 and the first fan 40 are both connected to the control member, and the control member controls the first fan 40 according to the temperature value detected by the first temperature detection member 80. In this way, it is convenient to effectively control the temperature in the control cabinet to achieve a better cooling effect. In addition, it is also convenient to effectively reduce the energy consumption of the control cabinet.

[0063] Specifically, when the temperature detected by the first temperature detection member 80 is greater than or equal to the first preset temperature, the control member controls the first fan 40 to start running; when the temperature detected by the first temperature detection member 80 is less than the first preset temperature, the control member controls the first fan 40 to stop running. When the temperature detected by the first temperature detection member 80 is between the first preset temperature and the second preset temperature, the second preset temperature is greater than the first preset temperature, the control member controls the first fan 40 to run at a first wind speed; when the temperature detected by the first temperature detection member 80 is between the second preset temperature and the third preset temperature, the third preset temperature is greater than the second preset temperature, the control member controls the first fan 40 to run at a second wind speed, the second wind speed is greater than the first wind speed.

[0064] Specifically, the first temperature detecting member 80 may be a temperature sensor.

[0065] Specifically, two or more fans may be provided on the mounting housing 30 , and according to the temperature detected by the first temperature detecting member 80 , the fans may be controlled to stop running, or one fan, two fans or multiple fans may be controlled to start running.

[0066] Specifically, the control cabinet also includes a movable part and a driving part. The movable part can be movably arranged at the first connecting port 31. The movable part has a blocking position for blocking the first connecting port 31 and a avoiding position for avoiding the first connecting port 31. The driving part is drivingly connected to the movable part. The driving part is connected to the control part, and the driving part controls the driving part according to the temperature detected by the first temperature detection part 80. With such a structural arrangement, when the first fan 40 is not needed to run, the movable part can be moved to the blocking position, thereby directly physically isolating the protective cavity 11 and the installation cavity, thereby better preventing foreign matter from entering the protective cavity 11 through the installation cavity, thereby better protecting the structure in the protective cavity 11.

[0067] In this embodiment, the control cabinet further includes a second temperature detection member, which is arranged on the cabinet body 10 and outside the protective cavity 11, and is used to detect the temperature outside the protective cavity 11. The control member controls the first fan 40 according to the temperature value detected by the first temperature detection member 80 and the temperature value detected by the second temperature detection member; when the temperature detected by the first temperature detection member 80 is greater than the temperature detected by the second temperature detection member, and the temperature difference between the temperature detected by the first temperature detection member 80 and the temperature detected by the second temperature detection member is greater than or equal to the preset difference, the control member controls the first fan 40 to rotate forward to introduce the air outside the protective cavity 11 into the protective cavity 11; when the temperature detected by the first temperature detection member 80 is greater than the temperature detected by the second temperature detection member, and the temperature difference between the temperature detected by the first temperature detection member 80 and the temperature detected by the second temperature detection member is less than the preset difference, the control member controls the first fan 40 to rotate reversely to blow the air in the protective cavity 11 to the outside of the protective cavity 11. By adopting such a method, when the temperature difference is large, external wind can enter the protective cavity 11, thereby effectively reducing the temperature in the protective cavity 11; when the temperature difference is small, a large amount of hot air in the protective cavity 11 is blown out as much as possible, thereby facilitating better reduction of the temperature in the protective cavity 11 to ensure the cooling effect.

[0068] Specifically, the control cabinet also includes a second fan 90, which is arranged in the protective cavity 11, the second fan 90 is spaced apart from the mounting shell 30, and the second fan 90 is connected to the control component, and the control component controls the second fan 90 according to the temperature value detected by the first temperature detection component 80. In this way, the second fan 90 can facilitate the circulation of the internal temperature in the protective cavity 11, ensure the uniformity of the temperature in the protective cavity 11, and avoid the situation where the temperature of some structures in the protective cavity 11 is too high, so as to facilitate better cooling of the structure in the protective cavity 11 and improve the cooling effect. Specifically, the second fan 90 can disturb the air in the protective cavity 11, accelerate the mixing of cold and hot air, and improve the heat dissipation efficiency.

[0069] Specifically, the cabinet 10 has at least two installation ports, which are respectively located on both sides of the cabinet 10; there are at least two installation housings 30, which are arranged one-to-one with the at least two installation ports, and the second communication ports 32 of each installation housing 30 are arranged opposite to the corresponding installation ports. Specifically, a fan can be arranged on one installation housing 30, and the other installation housing 30 is only used as a port for communication with the outside without being arranged with a fan; or, fans can be arranged on both installation housings 30.

[0070] Specifically, the electrical component 20 includes a first electrical component 21 and a second electrical component 22 arranged at intervals along a preset direction, the heat generated by the first electrical component 21 is greater than the heat generated by the second electrical component 22, and the first fan 40 is arranged on a side of the first electrical component 21 away from the second electrical component 22. With such a structural arrangement, it is possible to better improve the heat dissipation effect.

[0071] Specifically, the first electrical component 21 is a driver, and the second electrical component 22 is a control system.

[0072] This solution is a direct heat dissipation method for a small high-protection robot control cabinet. By optimizing the layout of the fan, the fan is installed in the same cavity as the electrical components. The heat of the components inside the control cabinet is directly discharged out of the cabinet with the air, and an internal circulation fan is added to increase the heat dissipation efficiency. At the same time, the fan installation cavity can isolate the external water and dust from the interior to a certain extent. The control cabinet has a certain dust and water resistance and is suitable for various harsh working environments.

[0073] Specifically, two cooling fans (cooling fans are also called first fans 40) can be installed on the mounting plate 50 and fixed by nuts; the cooling fans and the mounting plate 50 are fixed together in the protective cavity 11 by screws. A piece of dustproof cotton is stuffed into the dust cover, and then the dust cover is fixed above the right fan mounting cavity by screws. The internal circulation fan (internal circulation fan is also called second fan 90) is fixed to the fan bracket behind the control cabinet by screws; electrical components such as temperature sensors and relays are installed on the electrical rails; the driver is installed on the left side of the control cabinet, and the control system is installed on the right side of the control cabinet. Finally, the upper cover is fixed by screws.

[0074] Specifically, the working principle of the control cabinet in this embodiment is as follows: the cooling fan is installed in the installation shell 30 on the left side of the control cabinet, and is located in a large cavity with the electrical components. The hot air inside the control cabinet is directly sucked out of the cabinet body 10 from the left side by the way of air intake on the right side and air discharge on the left side, and the cold air from the outside enters the cabinet body 10 from the right side. Installing electronic components with large heat dissipation such as drivers on one side of the cooling fan is conducive to the cooling fan directly sucking heat out of the control cabinet, and installing electronic components with small heat dissipation or no heat on the other side to improve the heat dissipation efficiency. According to actual conditions, the cooling fan can be installed on either side. The mounting shell 30 is directly welded to the control cabinet 10, which has a certain isolation effect on the cooling fan and the outside world from the internal components. The mounting shell 30 has an opening on the top, so when water splashes in from the outside, it cannot enter the inside and will not affect the internal electronic components. At the same time, after the rubber plug is pulled out, the splashed water can be discharged from the drain port. There is a dust cover on the fan mounting cavity, and dust-proof cotton is contained in the dust cover to filter out dust from the air entering from the outside, so that the control cabinet can achieve a high protection effect. The dust-proof cotton can be removed and replaced after being used for a certain period of time.

[0075] Specifically, when the internal temperature is high, the internal circulation fan can disturb the internal air, causing the cold and hot air to mix quickly, thereby improving the heat dissipation efficiency.

[0076] Specifically, a temperature sensor is installed inside the electrical cabinet to monitor the internal temperature of the control cabinet in real time. When the load of the control cabinet is large, the temperature is high, and the control system controls all fans to start, increase the fan speed, and speed up the discharge of hot air. When the load of the control cabinet is small, the temperature is low, and the control system automatically turns off unnecessary fans according to the temperature to reduce overall power consumption.

[0077] Specifically, when the temperature is below 30°, a single cooling fan is started; when the temperature is between 30-45°, two cooling fans are started; when the temperature is above 45°, two cooling fans and an internal circulation fan are started. The number of cooling fans can be increased or decreased according to the actual heat generated inside the cabinet.

[0078] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: the present invention installs the first fan in the control cabinet, blows out the internal hot gas flow, introduces the external cold air, directly dissipates the heat of the control cabinet, and improves the heat dissipation efficiency. The fan installation cavity is welded to the solid, and the fan and the installation plate are installed in the protective cavity together. The installation cavity adopts the first connecting port with an upper opening. When water splashes in from the installation plate, it can prevent water from entering the protective cavity of the control cabinet to prevent the electronic components from being damaged by water. When water splashes into the installation cavity, the rubber plug installed on the fan installation plate is removed, and the water can flow out from the drain port of the fan installation plate; at the same time, a dust cover is installed on the fan installation cavity, and there is a layer of dustproof cotton inside the dust cover, which can filter the dust in the inhaled air, so that the control cabinet can have a certain dustproof and waterproof ability, and is suitable for various harsh working environments. Compared with the high-protection control cabinets on the market that use a double-layer arrangement of upper and lower cavities to achieve dust and water resistance, this solution can reduce the height of the control cabinet, and only one layer of cavity can achieve high protection functions, thereby reducing the overall volume and weight.
