[0036] With the continuous progress and development of the automatic guided vehicle (AGV) technology, the market demand for the endurance of AGV vehicles is gradually increasing. Due to the certain limitation caused by the compact internal space of AGV vehicles, the battery capacity is small and it is difficult to meet the demand for long-term operation. Therefore, in order to ensure that AGV vehicles can operate efficiently for a long time, it is necessary to use an external AGV charging pile to charge the storage battery. By using an advanced AGV charging pile, it can be ensured that the AGV vehicle always maintains an efficient and stable state during long-term operation, thus meeting the requirements of various complex application scenarios.

[0037] In the existing AGV charging piles, they are divided into two parts: a charging plug device and an AGV charger that supplies power to the charging plug device. The AGV charger and the charging plug device are separately set, resulting in a relatively large volume of the AGV charging pile. This not only causes the AGV charging pile to occupy more space in the usage environment, but also is inconvenient for handling and installation.

[0038] The present invention proposes a multifunctional automatic guiding and charging device.

[0039] Please refer to Figure 1 and Figure 2 , in an embodiment of the present invention, the multi-functional automatic guided charging device includes a housing 1, and the housing 1 has a receiving cavity 11;

[0040] A brush block module 3, the brush block module 3 is movably disposed in the receiving cavity 11, the brush block module 3 has a plugging position extending out of the receiving cavity 11, and a retracted position moved into the receiving cavity 11;

[0041] A control module 2, the control module 2 is disposed in the receiving cavity 11, the control module 2 is electrically connected to the brush block module 3, the control module 2 is used to control the brush block module 3 to switch between the plugging position and the retracted position, the control module 2 includes a converter and a power supply module 21, the converter is used to regulate the voltage and current of an external power supply to charge the power supply module 21, and the power supply module 21 is used to supply power to the brush block module 3; and

[0042] A lifting module 4, the lifting module 4 includes a lifting mechanism 41 and a base 42, the lifting mechanism 41 is disposed between the housing 1 and the base 42, and the lifting mechanism 41 is used to drive the housing 1 to lift relative to the base 42 to adjust the height of the housing 1 relative to the base 42;

[0043] The technical solution of the present invention uses a converter to regulate the voltage and current of an external power supply to charge the power supply module 21, and then supplies power to the brush block module 3 through the power supply module 21 to charge the AGV vehicle; by integrating the brush block module 3, the converter, the power supply module 21 and the lifting module 4 into the housing 1 in sequence, it is avoided that the charging plug 312 device needs to be additionally connected to a charger to access the external power supply, thereby eliminating the floor area required for the additional charger, and further solving the problem that the AGV charging device occupies more space in the use environment; in addition, the height of the housing 1 relative to the base 42 can be adjusted through the lifting module 4, thereby reducing the overall height of the AGV charging device from the ground, and further facilitating handling and installation.

[0044] In this embodiment, the housing 1 includes a main frame body, a first outer shell, and a second outer shell. Both sides of the main frame body have a first opening, and the first outer shell and the second outer shell surround the first opening so that an accommodation cavity 11 is formed inside the housing 1. Another outer side wall of the main frame body has a second opening communicating with the accommodation cavity 11. The second opening can be arranged at the lower part of the main frame body, so that it is convenient for the brush block module 3 to extend out of the second opening and align with the charging port on the AGV vehicle. It should be noted that the main frame body, the first outer shell, the second outer shell, and the first opening are not marked in the accompanying drawings of the specification. By electrically connecting the control module 2 and the brush block module 3, the control module 2 can control the brush block module 3. The control module 2 controls the brush block module 3 to extend out of the second opening and move to the plug-in position, so that the brush block module 3 is plugged into the charging port on the AGV vehicle for charging. After the charging is completed, the control module 2 controls the brush block module 3 to move to the retracted position inside the accommodation cavity 11, thereby improving the charging efficiency of the brush block module 3 for the AGV cart. In order to more conveniently supply power to the brush block module 3 by the control module 2, the control module 2 includes a converter and a power supply module 21. The converter is electrically connected to the power supply module 21, and the converter can be electrically connected to an external power supply through a conversion component. The voltage and current transmitted by the external power supply are regulated in terms of voltage and current by the converter and then supply power to the power supply module 21. At the same time, the power supply module 21 supplies power to the brush block module 3 to meet the power supply requirements of the power supply module 21, thereby ensuring that the power supply module 21 can provide stable power for the brush block module 3. In this application, by integrating the brush block module 3, the converter, and the power supply module 21 into the housing 1, the user only needs to plug the triangular plug electrically connected to the converter into the external power supply, so that the external power supply is transmitted to the converter through the triangular plug and the wire. The converter adjusts the current and voltage of the external power supply to charge the power supply module 21, and then the power supply module 21 supplies power to the brush block module 3, so that the brush block module 3 charges the AGV vehicle, thereby avoiding the need for the brush block module 3 to use an additional charger body to supply power from an external power supply, further reducing the space occupied by this application, and thus solving the problem of large space occupation of the AGV charging device.

[0045] In this embodiment, the present application further includes a lifting module 4. The lifting module 4 includes a base 42 and a lifting mechanism 41. The lifting mechanism 41 includes a first driving member and a transmission member. The transmission member can be set as a screw, and there can be multiple transmission members. The first driving member is drivingly connected to multiple transmission members. It should be noted that the first driving member and the transmission member are not marked in the accompanying drawings of the specification. Multiple transmission members are threadedly connected to the bottom of the housing 1 at intervals, and the other ends of the multiple transmission members are connected to the base 42 at intervals. The first driving member can be set as a driving motor or a driving motor that can synchronously drive multiple transmission members to rotate, so that the first driving member can drive the multiple transmission members to rotate, drive the housing 1 to lift relative to the base 42, and then adjust the ground clearance of the brush block module 3, so that the present application can adapt to the charging ports of AGV vehicles with different heights. In addition, through the lifting module 4, the housing 1 can be lifted to abut against the base 42, thereby reducing the overall height of the present application, and making it more convenient for handling and installation. Specifically, the transmission members can be set to four, and the four transmission members are connected to the four corners of the bottom of the housing 1 at intervals, so that the present application is not prone to tilt and shake when placed on the ground. The first driving member can also be set as a driving screw, and the transmission member is set as a hinge. Adjacent hinges can be hinged and matched through a connecting block. Thus, by manually rotating the first driving member by the user, the connecting block can be driven to reciprocate, so that the connecting block drives the transmission member to extend or contract, and then the distance between the housing 1 and the base 42 can be adjusted.

[0046] As Figure 2 shown, in this embodiment, the multifunctional automatic guided charging device further includes a first mounting bracket 5. The first mounting bracket 5 is disposed in the accommodating cavity 11. The accommodating cavity 11 has an air inlet and an air outlet. The first mounting bracket 5 has an air duct 51 communicating the air inlet and the air outlet. The power supply module 21 is disposed in the air duct 51.

[0047] In this embodiment, the first mounting bracket 5 is detachably disposed in the accommodating cavity 11, and the power supply module 21 is detachably mounted in the first mounting bracket 5, so that it is convenient for the user to detach the power supply module 21 from the accommodating cavity 11 by detaching the first mounting bracket 5, thus facilitating the disassembly and installation of the power supply module 21 during the maintenance work by the operator.

[0048] In this embodiment, air inlets and air outlets can be provided at both ends of the accommodating cavity 11 along its own extending direction. An air duct 51 for communicating the air inlet and the air outlet can be constructed inside the first mounting bracket 5. The power supply module 21 is disposed in the air duct 51, so that the air flow in the external environment can flow through the air inlet, the air duct 51 and the air outlet, thereby improving the heat dissipation efficiency of the power supply module 21.

[0049] As Figure 1 、 Figure 3 and Figure 4As shown, in this embodiment, the power supply module 21 includes a first frame 211, a first electronic component 212 disposed within the first frame 211, and a heat dissipation component 213 disposed at one end of the first frame 211. The first frame 211 is disposed within the air duct 51. The first electronic component 212 is electrically connected to the converter, and the heat dissipation component 213 is located at one end of the air duct 51 close to the air inlet.

[0050] In this embodiment, the first mounting bracket 5 has an air duct 51. Both the first electronic component 212 and the heat dissipation component 213 are disposed within the first frame 211, facilitating the detachable installation of the power supply module 21 on the inner wall of the air duct 51 through the first frame 211. Maintenance personnel can remove the first mounting bracket 5 to detach the power supply module 21 as a whole from the accommodation cavity 11, thus facilitating the maintenance of the power supply module 21.

[0051] In this embodiment, the heat dissipation component 213 may include a heat dissipation fan (not shown) and a barrier net (not shown) for dust and mosquito prevention, preventing mosquitoes and dust from entering the power supply module 21 from the air inlet. The heat dissipation component 213 is located at one end of the air duct 51 close to the air inlet, such that the first electronic component 212 is located between the air inlet and the air outlet. By means of the heat dissipation component 213, the flow rate of the air flow within the air duct 51 is increased, thereby further improving the heat dissipation efficiency of the power supply module 21.

[0052] As Figure 3 shown, in this embodiment, the power supply module 21 further includes a first connector 214. The power supply module 21 is electrically connected to the brush block module 3 through the first connector 214.

[0053] In this embodiment, the first connector 214 can be set as a conductive connector such as a copper busbar or an aluminum block. The first connector 214 can be provided in multiple pieces. The multiple pieces of the first connector 214 are connected to each other to form a bracket for guiding the layout of wire lines. The multiple pieces of the first connector 214 are also used to fix the wires connecting the first electronic component 212 and the brush block module 3, thereby improving the stability of the connection between the first electronic component 212 and the brush block module 3 through the wires.

[0054] As Figure 3 and Figure 4 shown, in this embodiment, the first mounting bracket 5 includes a cover plate 52 and a second frame 53 that are connected to each other. The power supply module 21 is disposed within the second frame 53. The second frame 53 is provided with side plates on both sides extending along the air duct 51. The second frame 53 has an opening located between the two side plates. The cover plate 52 is covered at the opening. One side of the side plate away from the air inlet has a first notch 531, and the first connector 214 is located within the first notch 531.

[0055] In this embodiment, by arranging the cover plate 52 to cover the open end of the second frame 53, an installation chamber for installing the power module 21 is formed between the cover plate 52 and the second frame 53, so that the components inside the power module 21 are all installed in the installation chamber, thus facilitating the installation and disassembly of the power module 21. At the same time, by arranging the cover plate 52 to seal the open end, it is more convenient to install other modules, and thus the space inside the accommodation cavity 11 can be utilized more reasonably.

[0056] In this embodiment, in order to facilitate the electrical connection between the power module 21 and the brush block module 3 through the first connecting member 214, a first notch 531 communicating with the accommodation cavity 11 is provided on one side of the side plate away from the air inlet. The first connecting member 214 is located at the first notch 531, so that the wires fixed on the first connecting member 214 can pass through the first notch 531 to electrically connect the brush block module 3, thus facilitating the wiring planning inside the accommodation cavity 11 more conveniently.

[0057] As Figure 3 and Figure 4 shown, in this embodiment, two power modules 21 are provided. The two power modules 21 are arranged in the second frame 53. The first connecting member 214 includes a first connecting section 2141 and a second connecting section 2142. Two first connecting sections 2141 are provided. The two first connecting sections 2141 are electrically connected to the two power modules 21 one by one. The two first connecting sections 2141 are both electrically connected to the second connecting section 2142, and the second connecting section 2142 is electrically connected to the brush block module 3.

[0058] In this embodiment, in order to further improve the application scope and flexibility of the present application, two power modules 21 can be provided. The two power modules 21 are arranged at intervals in the second frame 53 to ensure the stability and redundancy of the present application. The present application can flexibly select to use one or two power modules 21 according to the different battery capacities of the AGV vehicle. When the battery capacity is large, two power modules 21 can be synchronously enabled to provide a larger voltage and current to charge the battery; when the battery capacity is small, only one power module 21 can be selected, thus saving the usage cost of the present application, further improving the application scope of the power module 21, and then being able to be adjusted according to actual needs, and then ensuring the efficient operation of the present application in different situations. The two power modules 21 are arranged at intervals in the second frame 53 along the width direction of the second frame 53, so that the two power modules 21 are both in the air duct 51, thus ensuring the heat dissipation efficiency of the two power modules 21. At the same time, the space occupied by the two power modules 21 in the accommodation cavity 11 is reduced, and then the space utilization rate in the accommodation cavity 11 is improved.

[0059] In this embodiment, to ensure that the two power modules 21 can be started synchronously or separately, one end of each of the two first connection segments 2141 is electrically connected to the two power modules 21 one-to-one, and the other ends of the two first connection segments 2141 are both electrically connected to the brush block module 3 through the second connection segment 2142, so that the user can adjust the use of the power module 21 according to actual needs.

[0061] In this embodiment, the second mounting bracket 6 is detachably mounted on the cover plate 52, and the first mounting area 61 and the second mounting area 62 are spaced apart on the side of the second mounting bracket 6 away from the cover plate 52, so as to facilitate the installation of the main control board module 22 into the second mounting bracket 6. The first mounting area 61 and the second mounting area 62 can be spaced apart along the height direction of the housing 1. By mounting the second electronic component 221 in the first mounting area 61 and the third electronic component 222 in the second mounting area 62, the space utilization rate of the second mounting bracket 6 is improved.

[0062] In this embodiment, a touch screen can be installed on the outer side wall of the housing 1, the third electronic component 222 can be set as a first circuit board, the touch screen is electrically connected to the third electronic component 222, so that it is convenient for the user to issue commands to the touch screen to feedback signals to the third electronic component 222 to generate command signals, thereby simplifying the operation steps of this application. The second electronic component 221 can be set as a second circuit board, and the second electronic component 221 controls the brush block module 3 and the power module 21 to operate correspondingly according to the command signals.

[0063] As Figure 3 and Figure 10 shown, in this embodiment, the second mounting bracket 6 includes a bottom plate 63 and a support frame 64 that are connected to each other, the bottom plate 63 is arranged on the first mounting bracket 5, the bottom plate 63 has the first mounting area 61, and the side of the support frame 64 away from the bottom plate 63 has the second mounting area 62.

[0064] In this embodiment, the bottom plate 63 is detachably mounted on the cover plate 52, and the support frame 64 is detachably mounted on the bottom plate 63, so that the second mounting area 62 is suspended above the first mounting area 61, thereby providing a more convenient mounting space for the third electronic component 222. The second electronic component 221 and the third electronic component 222 are independently arranged on the second mounting bracket 6, thereby improving the space utilization of the second mounting bracket 6 and ensuring the independence and stability between the second electronic component 221 and the third electronic component 222.

[0065] As Figure 3 shown, in this embodiment, the main control board module 22 further includes a second connecting member 223 and a third connecting member 224.

The second connecting member 223 and the third connecting member 224 are also used to fix the wires connecting the second electronic component 221 and the power supply module 21, thereby improving the stability of the connection between the second electronic component 221 and the power supply module 21 through the wires.

[0067] In this embodiment, the bottom plate 63 is provided with a plurality of fixing posts (not marked), and the second connecting member 223 is mounted on the fixing posts, thereby improving the stability of the second connecting member 223 mounted on the bottom plate 63.

[0068] In this embodiment, the multifunctional automatic guided charging device further includes a conversion member. The outer side wall of the housing 1 has a charging port for electrically connecting the power supply module 21, and the conversion member passes through the charging port to electrically connect the power supply module 21.

[0069] In this embodiment, the conversion member (not marked) includes a conversion joint and a cable that are electrically connected to each other. The conversion joint can be electrically connected to the power supply module 21 through the cable passing through the charging port. The conversion joint can be electrically connected to the hand charging line connectors on different models of AGV vehicles, thereby solving the problem that the present application is not compatible with the hand charging line connectors of multiple AGV models, simplifying the operation steps for manually charging the AGV vehicle by the operator, and further enhancing the adaptability of the present application to different models of AGV vehicles.

[0070] As Figure 5 、 Figure 6 、 Figure 7and Figure 8 As shown in Figure 8 , in this embodiment, the brush block module 3 includes a brush block 31 and a second driving member 32 drivingly connected to the brush block 31. The brush block 31 includes a protective cover 311, a plug 312, and a buffer portion 313. The plug 312 is disposed inside the protective cover 311. The protective cover 311 has a third opening for the plug 312 to be exposed, and the buffer portion 313 is disposed at the third opening; and / or, a fireproof layer is provided on the inner sidewall of the protective cover 311.

[0071] In this embodiment, in order to prevent the user or the AGV vehicle from accidentally touching and getting an electric shock during the telescopic process of the brush block 31, the protective cover 311 has a receiving cavity. By disposing the plug 312 inside the receiving cavity of the protective cover 311 and providing an insulating layer on the outer sidewall of the protective cover 311, the metal part of the brush block 31 is completely wrapped during the telescopic and charging processes, so that the outside cannot touch the metal part of the brush block 31, thereby enhancing the safety performance of this application.

[0072] In this embodiment, a fireproof layer (not marked) may be provided on the inner wall of the receiving cavity. When a fire spark is generated due to an accidental short circuit of the metal part of the brush block 31, the fireproof layer can prevent the fire spark from burning inside the receiving cavity at the source, thereby further improving the safety performance of this application.

[0073] In this embodiment, a connecting portion 3111 may be provided at the third opening of the protective cover 311. The buffer portion 313 has a groove corresponding to the connecting portion 3111. The connecting portion 3111 is inserted into the groove so that the buffer portion 313 is sleeved on the protective cover 311. When the brush block 31 is inserted into the charging port of the AGV vehicle, the brush block 31 can buffer the impact force generated with the outer sidewall of the charging port of the AGV vehicle through the buffer portion 313, thereby avoiding damage during the connection and disconnection processes between the brush block 31 and the charging port of the AGV vehicle.

[0074] In this embodiment, the second driving member 32 can be set as an electric push rod or a cylinder, so that the second driving member 32 can drive the brush block 31 to move linearly in a direction close to or away from the second opening, so that the brush block 31 can be more accurately inserted into the charging port of the AGV vehicle. When the brush block 31 is in the inserted position, the whole brush block 31 is exposed outside the second opening. When the brush block 31 is in the retracted position, the whole brush block 31 is received in the accommodating cavity 11, thus avoiding the situation of accidental touch caused by the long-term exposure of the brush block 31 outside the second opening. By setting, this application further includes a first travel switch 7 and a second travel switch 71, and the first travel switch 7 and the second travel switch 71 can be respectively arranged on the brush block module 3. The first travel switch 7 can be set as a roller-type travel switch, and the contact end of the first travel switch 7 abuts against the second driving member 32. When the brush block 31 is in the inserted position, the contact end of the first travel switch 7 is disconnected from the second driving member 32, and the first travel switch 7 forms a first signal and feeds it back to the second driving member 32 to control the second driving member 32 to stop driving the brush block 31. When the brush block 31 is in the retracted position, the contact end of the second travel switch 71 abuts against the contact portion 3112 on the protective cover 311, and the second travel switch 71 forms a second signal and feeds it back to the second driving member 32 to control the second driving member 32 to stop driving the brush block 31. This application adopts the first travel switch 7 and the second travel switch 71 to accurately control the travel of the brush block 31 extending out of the second opening and inserting into the charging port of the AGV vehicle, as well as the travel of moving back to the initial position, thereby further improving the accuracy of the brush block 31 inserted into the charging port of the AGV vehicle, preventing the brush block 31 from hitting a hard obstacle during the extension process, and improving the accuracy of the brush block 31 moving to the initial position in the accommodating cavity 11, thus avoiding abnormal charging caused by position deviation during the telescopic process of the brush block 31.

[0075] In this embodiment, this application further includes a guiding component 8 and a connecting frame 9. By arranging the connecting frame 9 on the bottom wall of the accommodating cavity 11, and by setting that both the second driving member 32 and the guiding component 8 are arranged on the connecting frame 9, the stability of the movement of the brush block module 3 is improved, so that the brush block 31 is suspended in the accommodating cavity 11 and aligned with the second opening, and further facilitates the second driving member 32 to drive the brush block 31 to move in the accommodating cavity 11. By setting the guiding component 8 to connect the brush block 31, the extending direction of the guiding component 8 is the same as the driving direction of the second driving member 32, and the guiding component 8 can limit the brush block 31 to move linearly in a direction close to or away from the second opening, so as to guide the brush block 31 to extend or retract more accurately from the second opening. In order to improve the stability of the second driving member 32 driving the brush block 31 to move, guiding components 8 can be arranged on both sides of the second driving member 32.

[0076] In this embodiment, the present application further includes a third mounting bracket 91 connected to the connecting bracket 9. The guiding assembly 8 includes a guiding rod 81 and a guiding seat 82. The guiding rod 81 is connected to the brush block 31, and the guiding seat 82 is slidably sleeved on the guiding rod 81. The second driving member 32, the guiding rod 81, and the guiding seat 82 are respectively installed in the third mounting bracket 91. The third mounting bracket 91 includes a fixing member 911 for fixing the second driving member 32 and a third frame 912 provided on one side of the fixing member 911. The fixing member 911 is installed on the side of the connecting bracket 9 away from the brush block 31, and the third frame 912 is connected to the fixing member 911 and covers the connecting bracket 9. When the guiding assemblies 8 are arranged on both axial sides of the second driving member 32, the guiding seats 82 are slidably sleeved on the guiding rods 81 one by one, and the two guiding seats 82 are installed on the inner walls of both sides of the third frame 912, so that the two guiding assemblies 8 are respectively arranged on both sides of the second driving member 32, which is more convenient for adjusting the relative positions among the second driving member 32, the brush block 31, and the guiding assembly 8 during the production process, and further enables the second driving member 32 and the guiding assembly 8 to be more stably installed on the connecting bracket 9. The extending direction of the guiding rod 81 is the same as the driving direction of the second driving member 32, so that the guiding assembly 8 can better guide the brush block 31 to move linearly in the direction close to or away from the second opening, and improve the accuracy of the brush block 31 moving to the insertion position or the retracted position. One side of the third mounting bracket 91 close to the first travel switch 7 has a second notch 913, and the contact end on the first travel switch 7 passes through the second notch 913 and abuts against the guiding rod 81, so that the contact end on the first travel switch 7 and the guiding rod 81 are on the same horizontal plane, and further enables the first travel switch 7 to better abut against the guiding rod 81 and improve the accuracy of the first travel switch 7 forming the first signal. The guiding rod 81 on the side close to the first travel switch 7 is provided with a frustum portion for the first travel switch 7 to abut against, and the outer side wall of the frustum portion can be an arc surface. When the brush block 31 gradually moves to the insertion position, the contact end of the first travel switch 7 abuts against the frustum portion and gradually moves along the outer wall of the frustum portion to the end with a smaller inner diameter of the frustum portion, so that the contact end of the first travel switch 7 is disconnected from the guiding rod 81. When the brush block 31 starts to move towards the retracted position, the contact end of the first travel switch 7 starts to move from the end with a smaller inner diameter of the frustum portion and gradually moves along the outer wall of the frustum portion to the guiding rod 81, so that the contact end of the first travel switch 7 is restored to abut against the guiding rod 81, which is more convenient for the contact end of the first travel switch 7 to be disconnected from the guiding rod 81 or more convenient for the contact end of the first travel switch 7 to be restored to abut against the guiding rod 81.

[0077] In this embodiment, the present application further includes a third driving member 92. The third driving member 92 is drivingly connected to a third mounting bracket 91. The third mounting bracket 91 is movably disposed on the connecting bracket 9. The third driving member 92 is used to drive the third mounting bracket 91 to move relative to the connecting bracket 9, so as to adjust the height of the third mounting bracket 91 relative to the connecting bracket 9 in the height direction of the housing 1, and further adjust the height of the brush block 31 from the ground, so that the brush block 31 can be more accurately inserted into the charging port of the AGV vehicle. The side walls of the connecting bracket 9 along both sides in the width direction of the housing 1 are each provided with inclined holes 901 that are inclined with respect to the height direction of the housing 1. The side walls of the third mounting bracket 91 along both sides in the width direction of the housing 1 are each provided with connecting columns 914. The connecting columns 914 are movably inserted into the inclined holes 901.

[0078] As Figure 9 and Figure 10 shown, in this embodiment, the multifunctional automatic guided charging device further includes a first fan 225 and a filter screen 226. One side wall of the housing 1 close to the main control board module 22 has a fourth opening. The filter screen 226 is detachably covered on the outer side wall of the fourth opening away from the main control board module 22. The first fan 225 is disposed at the fourth opening. The main control board module 22 is located on the other side of the first fan 225 away from the filter screen 226.

[0079] In this embodiment, in order to reduce the influence of dust on the second electronic component 221 and the third electronic component 222 and cool the second electronic component 221 and the third electronic component 222, by disposing the first fan 225 on the inner wall of the fourth opening, the first fan 225 faces the second electronic component 221 and the third electronic component 222, so that the first fan 225 generates a negative pressure suction force, making the inside of the accommodation cavity 11 in a negative pressure state, so that the dust on the second electronic component 221 and the third electronic component 222 is sucked to the filter screen 226 and discharged to the external environment. At the same time, it can also cool the ambient temperature around the main control board module 22, thereby improving the service life of the second electronic component 221 and the third electronic component 222.

[0080] In this embodiment, in order to timely remove the dust on the plug 312 and cool the plug 312, by disposing the second fan 33 on the inner wall of the second opening, and setting a gap (not marked) on the side of the protective cover 311 close to the second fan 33, the second fan 33 conveys the air flow through the gap to the plug 312, thereby blowing away the dust on the plug 312, and at the same time, it can also cool the ambient temperature around the plug 312.
