This makes it difficult to dissipate the significant heat generated by the electrical equipment during operation, shortening the equipment's lifespan and potentially even causing accidents due to burnout of electrical components. Furthermore, the large number of integrated devices increases the overall weight and size of the control box, making it more difficult and expensive to transport the equipment.

[0048] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention more clearly understood, the technical solutions of the embodiments of the present invention are described in further detail below. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by those skilled in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0049] In the description of this utility model, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0050] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0051] The outdoor control box is an electrical control system box designed specifically for outdoor environments. It is waterproof and dustproof, and can withstand the influence of adverse weather conditions to ensure the normal operation of equipment and systems.

[0052] As can be seen from the background technology, in order to meet the needs of different working conditions, outdoor control boxes on the market generally integrate a large number of electrical devices with different functions. Electrical equipment will generate a lot of heat during operation. The more integrated devices there are, the greater the total power, and the greater the heat dissipation demand. If the heat dissipation is poor, it will cause the equipment to overheat, reducing its service life. In severe cases, it may even cause accidents due to burnout of electrical components. On the basis of allowing the outdoor control box to meet as many different working conditions as possible, in order to make the outdoor control box meet the needs of easy transportation for its outdoor use, the size of the outdoor control box should generally not be designed too large. This also brings greater challenges to the selection and layout of the heat dissipation equipment. In addition, the large number of integrated devices also leads to an increase in the overall weight and volume of the control box, which increases the difficulty and cost of transportation. It also requires a larger transportation space to be reserved for related transportation equipment, which makes it difficult to meet the use needs of narrow terrain.

[0053] It is worth mentioning that in order to meet the heat dissipation requirements of the control box, the existing control box generally improves the heat exchange efficiency inside and outside the box by adding a built-in fan. However, such a design cannot guarantee the sealing of the box, which is not conducive to the outdoor use of the control box. Moreover, adding a fan to improve the heat dissipation efficiency also requires increasing the size of the chassis to accommodate the fan, which also leads to an increase in the manufacturing cost and space occupied by the outdoor control box.

[0054] In view of this, the present embodiment provides an outdoor control box, which arranges the heat dissipation system and the power system in the control box body so that the outdoor control box can not only meet the heat dissipation needs of its internal electrical equipment, but also has the function of self-propelled transportation, thereby solving a series of problems mentioned in the above background technology.

[0055] Please refer to the attached drawings of the specification. The outdoor control box includes a control box body 10. The control box body 10 serves as the supporting base of the outdoor control box and is usually made of high-strength materials (such as aluminum alloy, stainless steel, etc.). It must have waterproof, dustproof, corrosion-resistant and other properties to adapt to the complex and changeable outdoor environmental conditions.

[0056] In this embodiment, a hollow first accommodating chamber 11 is formed within the control box body 10. The first accommodating chamber 11 is used to provide sufficient installation space for electrical equipment corresponding to the outdoor control box. For example, the control box body 10 may be equipped with, but is not limited to, a switch, a power supply, an industrial computer, and the like. In this embodiment, a battery 12 serving as a power source is fixedly mounted within the first accommodating chamber 11. A photovoltaic panel 13 is disposed on the exterior of the control box body 10 and electrically connected to the battery 12. The photovoltaic panel 13 utilizes the photovoltaic effect (i.e., the interaction of photons with materials within the photovoltaic panel 13 to generate current) to directly convert sunlight into direct current (DC). This converted DC electricity is then transferred to the battery 12 for storage via appropriate circuits and equipment (such as a charge controller). This allows the battery 12 to provide electricity even in low-light conditions or at night when direct solar energy is unavailable. This conversion process requires no fuel and produces no greenhouse gas emissions, making it a clean, renewable energy conversion method. This also satisfies the need for the outdoor control box to remain uncharged during outdoor operation.

[0057] On the basis of the above, the outdoor control box also includes a heat dissipation system 20 and a power system 30. The heat dissipation system 20 includes a semiconductor heat dissipation device 21 and a heat dissipation fan 22 arranged outside the control box body 10. The semiconductor heat dissipation device 21 and the heat dissipation fan 22 are both electrically connected to the battery 12 to power the semiconductor heat dissipation device 21 and the heat dissipation fan 22 when the battery 12 stores sufficient electrical energy. The semiconductor heat dissipation device 21 mainly works based on the Peltier effect. When a direct current passes through a galvanic couple composed of two different semiconductor materials (such as N-type and P-type semiconductors), heat absorption or heat release occurs at the joint. One of the joints becomes the cold end, absorbing heat, and the other joint becomes the hot end, releasing heat. The semiconductor heat dissipation device 21 is attached to the surface of the control box body 10 through its cold end, specifically to the place where the heat generation of the control box body 10 is the highest, so as to transfer heat from the first accommodating cavity 11 and the surface of the control box body 10 to the semiconductor material. The cooling fan 22 is rotatably disposed at the hot end of the semiconductor heat sink 21. Under the action of the battery 12, the cooling fan 22 can rotate relative to the semiconductor heat sink 21 to blow away or extract the heat emitted by the hot end of the semiconductor heat sink 21, thereby accelerating the heat exchange efficiency between the hot end of the semiconductor heat sink 21 and the external environment of the outdoor control box, thereby achieving the purpose of heat dissipation.

[0058] In addition to improving the heat dissipation efficiency of the control box body 10, the semiconductor heat dissipation device 21 can also reduce the use of the fan in the first accommodating cavity 11, thereby reducing the generation of noise, which is beneficial to the miniaturization design of the control box body 10 and expands the application occasions of outdoor control boxes.

[0059] The power system 30 includes a drive device 31 and a drive wheel 32. The drive device 31 is arranged in the first accommodating cavity 11 and is electrically connected to the battery 12, while the drive wheel 32 is rotatably arranged outside the control box body 10 and is driven to cooperate with the drive device 31. The drive device 31 outputs driving force to the drive wheel 32 or stops outputting driving force to the drive wheel 32 by turning the battery 12 on and off. Specifically, the drive device 31 is the core part of the power system 30, which is responsible for converting the electrical energy provided by the battery 12 into mechanical energy, thereby driving the movement of the control box body 10 through the drive wheel 32. Common drive devices 31 include but are not limited to electric motors, hydraulic drive devices 31, pneumatic drive devices 31, etc. The drive wheel 32 can adopt wheel bodies of different sizes or materials according to the actual use conditions of the outdoor control box, such as rubber wheels, polyurethane wheels, metal wheels, etc.

[0060] The outdoor control box is provided with a heat dissipation system 20 and a power system 30 on the control box body 10, so that the outdoor control box can not only have the heat dissipation function, but also can be transported by itself through the power system 30. The heat dissipation system 20 accelerates the discharge of heat from the surface of the control box body 10 through the semiconductor heat dissipation device 21, and the heat dissipation fan 22 can accelerate the heat exchange efficiency between the cold end and the hot end of the semiconductor heat dissipation device 21, thereby meeting the heat dissipation requirements of multiple electrical equipment integrated into the control box body 10 and reducing the risk of damage to the outdoor control box due to failure. The power system 30 drives the drive wheel 32 to move through the drive device 31, so that the control box body 10 can be driven by the drive wheel 32, so that the control box body 10 can move on its own without the help of other transport equipment, so that the space required for the outdoor control box to be transported is greatly reduced, and the difficulty and cost of transportation are reduced.

[0061] In addition, the cooling system 20 and the power system 30 are both powered by a battery 12, thereby reducing the installation space occupied by the power supply in the control box body 10, which is conducive to the miniaturization design of the outdoor control box. Moreover, the battery 12 is charged by the photovoltaic panel 13, making the device more low-carbon and environmentally friendly.

[0062] Taking the above-mentioned embodiment as the basis of the present invention, in further embodiments, please continue to refer to the accompanying drawings. One end of the photovoltaic panel 13 is hinged to the control box body 10, so that it has the freedom of movement to swing relative to the control box body 10 while maintaining a connection relationship with the control box body 10. In addition, an adjustment component 131 is further provided between the photovoltaic panel 13 and the control box body 10. The adjustment component 131 is used to drive the photovoltaic panel 13 to rotate around its hinge axis relative to the control box body 10, thereby realizing the adjustment of the photovoltaic panel 13 on the control box body 10.

[0063] Specifically, the hinge axis between the photovoltaic panel 13 and the control box body 10 is set horizontally so that the photovoltaic panel 13 can realize an upside-down flipping activity mode relative to the control box body 10. It is understandable that the rotatable photovoltaic panel 13 can freely adjust the angle and direction through the adjustment component 131 according to different seasons, time periods and sun positions, so that the surface of the photovoltaic panel 13 is as perpendicular to the incident direction of sunlight as possible, and can better adapt to different lighting conditions, thereby maximizing the reception of solar energy, thereby significantly improving the power generation efficiency of the photovoltaic panel 13, and ensuring that the best power generation effect can be obtained in different time periods of the day and different seasons of the year. In addition, the photovoltaic panel 13 that can be flipped up and down can be set to a downward flipped state when the outdoor control box is not in use, so that the photovoltaic panel 13 is as close to the side wall of the control box body 10 as possible, so as to achieve the purpose of improving the integrity of the control box body 10, reducing the space occupancy rate when not in use, making the control box body 10 easier to carry, and reducing the probability of the photovoltaic panel 13 being bumped and damaged.

[0064] It should be understood that the structure of the adjustment component 131 may depend on its application scenario and functional requirements. It can be, but is not limited to, a screw pair, a cylinder, an oil cylinder, a cam mechanism, etc., and this embodiment does not impose strict limitations and requirements on this. Of course, in some embodiments, the adjustment component 131 is not limited to being set to an electrically controlled adjustment method. It can adopt a manually controlled adjustment method, such as by arranging a plurality of latch teeth on an adjustment rod connected to the photovoltaic panel 13, and providing a latch portion that can be engaged with the above-mentioned latch on the control box body 10, so that any latch can be locked on the latch portion through manual adjustment, thereby realizing the telescopic position of the adjustment rod on the control box body 10, and realizing the raising or lowering of the photovoltaic panel 13.

[0065] In one embodiment, referring to the accompanying drawings, the outdoor control box further includes a sensor housing 40, which is mounted on one side of the control box body 10. A second accommodating chamber 41 is formed within the sensor housing 40. The second accommodating chamber 41 is used to accommodate a sensor probe of the outdoor control box. The sensor probe of the outdoor control box is responsible for monitoring the external environment or the state of the control box interior and feeding back relevant information to the control system of the outdoor control box. The sensor probe can be provided with, but is not limited to, a temperature sensor, a smoke sensor, a humidity sensor, a gas sensor, a light sensor (illuminance sensor), etc., depending on the actual use of the outdoor control box. Furthermore, the sensor probe can be connected to the control system of the outdoor control box via a wire, so that the sensor probe can be removed from the second accommodating chamber 41 for use.

[0066] Based on the above-described structure, the semiconductor heat sink 21 and the cooling fan 22 are both disposed within the second accommodating chamber 41, enabling the sensor housing 40 to simultaneously protect the sensor probe, the semiconductor heat sink 21, and the cooling fan 22, thereby providing dustproof, moisture-proof, and collision-proof functions. The sensor housing 40 also has an opening (not shown) on the side facing away from the control box body 10 that connects to the second accommodating chamber 41. The cooling fan 22 is positioned directly opposite the opening, allowing heat emitted from the hot end of the semiconductor heat sink 21 to be directly drawn out of the second accommodating chamber 41 via the cooling fan 22. This prevents heat accumulation within the second accommodating chamber 41, which could cause overheating and damage to the sensor probe or even the electrical equipment within the control box body 10.

[0067] Through the above-mentioned setting, it is possible to ensure that the semiconductor heat dissipation device 21 can stably improve the heat dissipation phase ratio of the control box body 10 while providing effective protection for the semiconductor heat dissipation device 21 and the cooling fan 22. In addition, it also provides a corresponding accommodation space for the sensor probe of the outdoor control box, thereby reducing the risk of collision and damage to related components of the outdoor control box during transportation, and playing a role in dust and moisture prevention, thereby extending the service life of the sensor probe, the semiconductor heat dissipation device 21 and the cooling fan 22, and reducing the influence of the external environment on the heat exchange effect of the semiconductor heat dissipation device 21.

[0068] In one embodiment, based on the aforementioned embodiment in which the outdoor control box also includes a sensor housing 40, in combination with the technical solution of hingedly coupling the photovoltaic panel 13 to the sensor housing 40, the hinged connection between the photovoltaic panel 13 and the sensor housing 40 is located above the opening. The photovoltaic panel 13 can cover or open the opening under the control of an adjustment assembly 131. In this way, when the photovoltaic panel 13 is tilted upward relative to the control box body 10, it can provide shade for the opening, preventing direct sunlight from reaching the opening. This reduces the temperature of the cooling fan 22 and the hot end of the semiconductor heat sink 21 provided corresponding to the opening, thereby ensuring the heat dissipation effect of the semiconductor heat sink 21 and the cooling fan 22. When the photovoltaic panel 13 is tilted downward and substantially adjacent to the control box body 10, it can block the opening, preventing dust and moisture from entering the second accommodating chamber 41 through the opening, thus providing a certain degree of protection when the outdoor control box is not in use.

[0069] Please continue to refer to the accompanying drawings. Furthermore, the second accommodating chamber 41 is filled with a sponge pad 42. The sponge pad 42 can allow the sensor probe to be stably placed in the second accommodating chamber 41 when not in use, so as to improve the protective effect of the sensor box 40 on the sensor probe. Since the sponge pad 42 has a certain deformation ability, the sponge pad 42 can be completely filled in the second accommodating chamber 41, so that the sensor probe can be stored in the second accommodating chamber 41 by squeezing the sponge pad 42, or the sponge pad 42 can be opened with a corresponding receiving groove according to the actual structure of the sensor probe, so that the sensor probe can be embedded in the sponge pad 42 through the corresponding receiving groove for storage.

[0070] On the basis of the above, in order to avoid the presence of the sponge pad 42 affecting the heat dissipation efficiency of the cooling fan 22 and the semiconductor heat dissipation device 21, a heat dissipation channel 421 is passed through the sponge pad 42, and an opening is set at one end of the heat dissipation channel 421. The semiconductor heat dissipation device 21 and the heat dissipation fan 22 are both set in the heat dissipation channel 421, so that the semiconductor heat dissipation device 21 can normally exchange the heat on the surface of the control box body 10 from the cold end to the hot end, and allow the heat emitted by the hot end to be normally discharged from the opening through the heat dissipation wind field.

[0071] In one embodiment, referring to the accompanying drawings, the power system 30 includes a drive unit 31 and drive wheels 32, and further includes a control circuit board 33 and an obstacle avoidance sensor 34. The control circuit board 33 is responsible for receiving signals from the obstacle avoidance sensor 34, user input, or other control sources, and accurately controls the drive unit 31 based on these signals. Generally speaking, the control circuit board 33 is typically composed of components such as a processing unit, memory, and input / output interfaces. To meet the outdoor use requirements of the outdoor control box, the control circuit board 33 can also be combined with a wireless communication module to enable remote monitoring and control of the outdoor control box. The obstacle avoidance sensor 34 is a component in the power system 30 used to detect obstacles and avoid collisions with the outdoor control box. Common obstacle avoidance sensors 34 are not limited to infrared sensors, ultrasonic sensors, lidars, etc. The obstacle avoidance sensor 34 detects obstacles in the surrounding environment by transmitting and receiving signals, and transmits the detected information to the control circuit board 33 for processing. According to the information of the obstacle avoidance sensor 34, the control circuit board 33 can adjust the output of the drive device 31 so that the drive wheel 32 can start, stop or turn, thereby bypassing obstacles or taking other obstacle avoidance measures, thereby achieving the purpose of reducing the risk of collision of the outdoor control box during self-propelled transportation.

[0072] It should be understood that in order to facilitate the communication connection between the control circuit board 33 and the drive device 31, the control circuit board 33 can be arranged in the first accommodating cavity 11, and the obstacle avoidance sensor 34 is arranged on the outside of the control box body 10 on the basis of the communication connection with the control circuit board 33, so as to detect obstacles outside the outdoor control box.

[0073] In addition, obstacle avoidance sensors 34 are provided on at least two sides, with at least two obstacle avoidance sensors 34 being located on opposite sides of the control box body 10, thereby expanding the detection range of the control box body 10 for the surrounding environment. In some embodiments, the number of obstacle avoidance sensors 34 provided may also be determined based on the specific structural form of the control box body 10. For example, if the control box body 10 is rectangular, four or more obstacle avoidance sensors 34 may be provided, so that the obstacle avoidance sensors 34 can be located at least at the four corners of the control box body 10, or even arranged in a height-wise arrangement, ensuring that the surrounding environment of the control box body 10 (and the sensor box 40) is within the detection range of the obstacle avoidance sensors 34, thereby improving the obstacle avoidance capability of the outdoor control box during self-propelled operation.

[0074] Please refer to the accompanying drawings. In one embodiment, the driving device 31 is configured as a dual-axis motor. It can be understood that the dual-axis motor is also called a dual-wire motor, which means that there are different motors or output devices on two axes, which can output two different torques or rotation directions at the same time, or, a motor or output device is used on one axis to output the same torque or direction.

[0075] Specifically, a first output shaft 311 and a second output shaft 312 are respectively provided at the opposite ends of the driving device 31. Correspondingly, two driving wheels 32 are provided. The first output shaft 311 is connected to one of the driving wheels 32 through a first worm gear mechanism 35, and the second output shaft 312 is connected to the other driving wheel 32 through a second worm gear mechanism.

[0076] It is understood that the first worm gear mechanism 35 and the second worm gear mechanism 36 have the same structure, and both include a worm body and a turbine body, wherein one worm body is connected to the first output shaft 311 or the second output shaft 312 in a transmission manner (such as a coaxial connection), so that the worm body can rotate with the corresponding output rotation, and the turbine body is meshed with the worm body for transmission, and the drive wheel 32 is installed on the turbine body. In this way, during the rotation of the worm body, the turbine body drives the drive wheel 32 to rotate during the rotation process, thereby realizing the movement of the outdoor control box. This embodiment uses the first turbine worm mechanism and the second turbine worm mechanism to realize the transmission between the drive device 31 and the drive wheel 32, which can realize the self-locking of the drive wheel 32 when the drive device 31 stops moving, ensuring the stability of the outdoor control box in the corresponding operating environment when the power system 30 is not in operation, without the need for additional braking devices, thereby improving the space utilization rate within the outdoor control box. At the same time, the worm gear mechanism also has good stability, which can ensure the stability of the outdoor control box during self-propelled operation.

[0077] It is understandable that in order for the control box body 10 to be stably supported on the ground, in addition to being provided with two or more driving wheels 32, the control box body 10 also needs to be provided with at least one driven wheel 100. The present embodiment does not impose strict restrictions and requirements on the specific position of the driven wheel 100 on the control box body 10, as long as it is ensured that the control box body 10 can maintain stable support on the ground with the cooperation of the driving wheel 32 and the driven wheel 100.

[0078] It is worth mentioning that, in the aforementioned drive device 31, when the first output shaft 311 and the second output shaft 312 are configured as two independent output shafts, the steering movement of the control box body 10 can be achieved by the first output shaft 311 and the second output shaft 312 outputting different rotational speeds. In contrast, when the first output shaft 311 and the second output shaft 312 are configured as an integrated rotating shaft component, the steering movement of the control box body 10 can be achieved by further providing a steering motor between the drive device 31 and the control box body 10.

[0079] In one embodiment, the semiconductor heat sink 21 includes a first heat conducting plate 211 and a second heat conducting plate 212. The first heat conducting plate 211 serves as the cold end of the semiconductor heat sink 21 and is attached to the outer surface of the control box body 10. The second heat conducting plate 212 serves as the hot end of the semiconductor heat sink 21. The first and second heat conducting plates 211, 212 are connected by a plurality of semiconductor pillars 213. Specifically, the first heat conducting plate 211 serves as the heat receiving end of the semiconductor heat dissipation device 21 and is responsible for transferring the heat received from the heat source (control box body 10) to the semiconductor column 213, while the second heat conducting plate 212 serves as the heat dissipation end of the semiconductor heat dissipation device 21 and is responsible for dissipating the heat transferred from the semiconductor column 213 to the environment. The semiconductor column 213 realizes the heat transfer between the first heat conducting plate 211 and the second heat conducting plate 212 through the thermoelectric effect, so that the temperature of the first heat conducting plate 211 is lower than that of the second heat conducting plate 212 (and even the surface of the control box body 10), thereby playing the role of cooling the surface of the control box body 10. Compared with the traditional air blowing heat dissipation method, its heat dissipation efficiency is higher.

[0080] Furthermore, the cooling fan 22 is installed on the second heat conducting plate 212 so that the air that has absorbed the heat from the second heat conducting plate 212 can be quickly discharged, thereby quickly replenishing the air with a relatively lower temperature and maintaining heat exchange with the second heat conducting plate 212 again.

[0081] Based on any of the above embodiments, please refer to the accompanying drawings. A micro voltage transformer 50 and a three-position power electronic switch 60 are further provided in the first accommodating chamber 11. The cooling fan 22 and the semiconductor heat sink 21 are connected in parallel. The battery 12 is connected in series with the parallel-connected cooling fan 22 and the semiconductor heat sink 21 via the three-position power electronic switch 60 to form a discharge circuit. The photovoltaic panel 13 is connected to the battery 12 via the micro voltage transformer 50 and the three-position power electronic switch 60 to form a charging circuit. The drive device 31 is connected in parallel with the micro voltage transformer 50 and the battery 12. The micro voltage transformer 50 is used to monitor the charge level of the battery 12. When it is detected that the battery 12 needs to be charged, the micro voltage transformer sends a signal to the three-position power electronic switch 60, connecting the photovoltaic panel 13 and the battery 12, and disconnecting the battery 12 from the load, thereby charging the battery 12. When the micro voltage transformer 50 detects that the battery 12 has been fully charged, it sends a signal to the three-position power electronic switch 60, disconnecting the photovoltaic panel 13 and the battery 12 from the load, allowing the battery 12 to resume powering the cooling system 20 and the power system 30.

[0082] In one embodiment, the outdoor control box further includes a display screen 70 rotatably disposed on the top of the control box body 10 for displaying relevant parameters of the outdoor control box and some operating parameters detected by its sensor probe.

[0083] The first chamber 11 also houses an industrial control computer housing 80 and a data collector housing 90. These housings, along with the battery 12, are spaced and arranged side by side on the upper side of the first chamber 11. The upper portion of the control box body 10 provides buttons corresponding to the industrial control computer, sensor probes, and other control keys, facilitating user operation of the outdoor control box. Correspondingly, the cooling system 20 and power system 30 are located on the lower side of the first chamber 11, enhancing the overall compactness and integrity of the outdoor control box.
