[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] With the continuous advancement and development of automatic guided vehicle (AGV) technology, the market demand for AGV endurance is also gradually increasing. Due to the compact internal space of AGV vehicles, it has certain limitations, which makes its battery capacity small and difficult to meet the needs of long-term operation. Therefore, in order to ensure that the AGV vehicle can run efficiently for a long time, it is necessary to use an external AGV charging pile to charge the battery. By using advanced AGV charging piles, it can be ensured that the AGV vehicle always maintains an efficient and stable state during long-term operation, thereby meeting the needs of various complex application scenarios.

[0037] The existing AGV charging pile is divided into two parts: a charging plug device and an AGV charger for supplying power to the charging plug device. The AGV charger and the charging plug device are separately arranged, so that the AGV charging pile has a large volume, which not only causes the AGV charging pile to occupy more space in the use environment, but also makes it inconvenient to carry and install.

[0038] The invention provides a multifunctional automatic guided charging device.

[0039] See also Figure 1 and Figure 2 , in one embodiment of the present invention, the multifunctional automatic guided charging device comprises a housing 1, wherein the housing 1 has a receiving cavity 11;

[0040] A brush block module 3, wherein the brush block module 3 is movably disposed in the accommodating cavity 11, and the brush block module 3 has an insertion position extending out of the accommodating cavity 11, and a retracted position moving into the accommodating cavity 11;

[0041] A control module 2, wherein the control module 2 is disposed in the accommodating cavity 11, the control module 2 is electrically connected to the brush block module 3, and the control module 2 is used to control the brush block module 3 to switch between the plug-in position and the retracted position. The control module 2 includes a converter and a power module 21, wherein the converter is used to adjust the voltage and current of an external power supply to charge the power module 21, and the power module 21 is used to supply power to the brush block module 3; and

[0042] A lifting module 4, the lifting module 4 comprising a lifting mechanism 41 and a base 42, the lifting mechanism 41 being disposed between the housing 1 and the base 42, the lifting mechanism 41 being used to drive the housing 1 to rise and fall relative to the base 42, so as to adjust the height of the housing 1 relative to the base 42;

[0043] The technical solution of the present invention adopts a converter to adjust the voltage and current of the external power supply for charging the power module 21, and then supplies power to the brush block module 3 through the power module 21 for charging the AGV vehicle; by integrating the brush block module 3, the converter, the power module 21 and the lifting module 4 in the shell 1 in sequence, the need for the charging plug 312 device to be additionally connected to a charger to access an external power source is avoided, thereby eliminating the floor space required for the additional charger, and solving the problem of the AGV charging device occupying more space in the use environment; in addition, the lifting module 4 can adjust the height of the shell 1 relative to the base 42, thereby reducing the overall height of the AGV charging device from the ground, making it more convenient to carry and install.

[0044] In this embodiment, the housing 1 includes a main frame, a first shell and a second shell, and the two sides of the main frame have a first opening, and the first shell and the second shell are arranged around the first opening, so that a housing cavity 11 is formed inside the housing 1. The other outer side wall of the main frame has a second opening connected to the housing cavity 11, and the second opening can be arranged at the lower part of the main frame, so that the brush block module 3 is aligned with the charging port on the AGV vehicle after extending out of the second opening. It should be noted that the main frame, the first shell, the second shell and the first opening are not marked in the drawings of the specification. By setting the control module 2 to be electrically connected with the brush block module 3, the control module 2 controls the brush block module 3 to extend from the second opening and move to the plug-in position, so that the brush block module 3 is plugged and charged with the charging port on the AGV vehicle. After charging is completed, the control module 2 controls the brush block module 3 to move to the retracted position in the housing cavity 11, thereby improving the efficiency of the brush block module 3 charging the AGV vehicle. In order to make it more convenient for the control module 2 to power the brush block module 3, the control module 2 includes a converter and a power module 21. The converter is electrically connected to the power module 21. The converter can be electrically connected to an external power supply through a conversion element. The voltage and current transmitted by the external power supply are both regulated by the converter to power the power module 21. At the same time, the power module 21 supplies power to the brush block module 3 to meet the power supply requirements of the power module 21, thereby ensuring that the power module 21 can provide stable power for the brush block module 3. The present application integrates the brush block module 3, the converter and the power module 21 in the housing 1, so that 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, and the external power supply is regulated by the converter to charge the power module 21, and then the power 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 external power supply of the charger body, thereby reducing the space occupied by the present application, and thus solving the problem of large space occupied by the AGV charging device.

[0045] In this embodiment, the present application also includes a lifting module 4, which includes a base 42 and a lifting mechanism 41. The lifting mechanism 41 includes a first driving member and a transmission member, which can be set as a screw, and the transmission member can be set as multiple, and the first driving member drives and connects multiple transmission members. It should be noted that the first driving member and the transmission member are not marked in the 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 multiple transmission members to rotate, so as to drive the housing 1 to rise and fall relative to the base 42, and then adjust the height of the brush block module 3 from the ground, so that the present application can adapt to the charging port of AGV vehicles of different heights. In addition, the housing 1 can be lifted and lowered to abut the base 42 by the lifting module 4, thereby reducing the overall height of the present application, and making it more convenient to carry and install. Specifically, the transmission member 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 easy 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 hingedly matched through connecting blocks, so that the user can manually rotate the first driving member to drive the connecting block to reciprocate, so that the connecting block drives the transmission member to extend or tighten, thereby adjusting the distance between the shell 1 and the base 42.

At the same time, by providing the cover plate 52 to seal the opening, it is more convenient to install other modules, so as to better and more reasonably utilize the space inside the accommodating cavity 11.

[0056] In this embodiment, in order to facilitate the power module 21 to be electrically connected to the brush block module 3 through the first connecting member 214, a first notch 531 connected to the accommodating chamber 11 is provided on the side of the side panel away from the air inlet, and 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 be electrically connected to the brush block module 3, thereby making it more convenient to plan the wire lines inside the accommodating chamber 11.

[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 the direction close to or away from the second opening, so that the brush block 31 can be more accurately plugged into the charging port of the AGV vehicle. When the brush block 31 is in the plug-in position, the brush block 31 is exposed outside the second opening as a whole, and when the brush block 31 is in the retracted position, the brush block 31 is stored in the accommodating cavity 11 as a whole, thereby avoiding the brush block 31 being exposed outside the second opening for a long time and causing a false touch.

When the brush block 31 is in the plug-in 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 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 back to the second drive member 32 to control the second drive member 32 to stop driving the brush block 31. The present application uses the first travel switch 7 and the second travel switch 71 to accurately control the stroke of the brush block 31 extending out of the second opening to plug into the charging port of the AGV vehicle, and the stroke of moving back to the initial position, thereby further improving the accuracy of the brush block 31 plugging into the charging port of the AGV vehicle, thereby 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 chamber 11, thereby avoiding charging abnormalities caused by position deviation of the brush block 31 during the extension process.

[0075] In this embodiment, the present application further includes a guide assembly 8 and a connecting frame 9. By arranging the connecting frame 9 on the bottom wall of the accommodating chamber 11, and by arranging the second driving member 32 and the guide assembly 8 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 chamber 11 and aligned with the second opening, so that it is more convenient for the second driving member 32 to drive the brush block 31 to move in the accommodating chamber 11. By arranging the guide assembly 8 to connect the brush block 31, the extension direction of the guide assembly 8 is consistent with the driving direction of the second driving member 32, and the guide assembly 8 can limit the brush block 31 to move linearly in the direction close to or away from the second opening, thereby guiding the brush block 31 to extend or retract from the second opening more accurately. In order to improve the stability of the second driving member 32 driving the brush block 31 to move, the guide assembly 8 can be provided on both sides of the second driving member 32.

The third mounting frame 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 frame 9 away from the brush block 31, and the third frame 912 is connected to the fixing member 911 and covered on the connecting frame 9. When the guide assembly 8 is arranged on both sides of the axial direction of the second driving member 32, the guide seats 82 are slidably sleeved on the guide rod 81 one by one, and the two guide seats 82 are installed on the inner walls of the third frame 912 on both sides, so that the two guide assemblies 8 are respectively arranged on both sides of the second driving member 32, so that it is more convenient to adjust the relative positions between the second driving member 32, the brush block 31 and the guide assembly 8 during the production process, and then the second driving member 32 and the guide assembly 8 are more stably installed on the connecting frame 9. The extension direction of the guide rod 81 is the same as the driving direction of the second driving member 32, so that the guide assembly 8 can better guide the brush block 31 to move linearly in the direction close to or away from the second opening, thereby improving the accuracy of the brush block 31 moving to the plug-in position or the retracted position. The third mounting frame 91 has a second notch 913 on the side close to the first travel switch 7. The contact end of the first travel switch 7 is inserted into the second notch 913 and abuts the guide rod 81, so that the contact end of the first travel switch 7 and the guide rod 81 are on the same horizontal plane, thereby making the first travel switch 7 better abut against the guide rod 81, and improving the accuracy of the first signal formed by the first travel switch 7. The guide rod 81 close to the side of the first travel switch 7 is provided with a truncated cone portion for abutment by the first travel switch 7, and the outer wall of the truncated cone portion can be an arc surface. When the brush block 31 gradually moves to the plug-in position, the contact end of the first travel switch 7 abuts against the truncated cone portion and gradually moves along the outer wall of the truncated cone portion to the end of the truncated cone portion with a smaller inner diameter, thereby making the contact end of the first travel switch 7 disconnect from the guide rod 81. When the brush block 31 starts to move toward the retracted position, the contact end of the first stroke switch 7 starts to move from the end of the conical portion with a smaller inner diameter, and gradually moves along the outer wall of the conical portion to the guide rod 81, so that the contact end of the first stroke switch 7 and the guide rod 81 are restored to abutment, thereby making it easier for the contact end of the first stroke switch 7 to disconnect from the guide rod 81 or for the contact end of the first stroke switch 7 to restore abutment with the guide rod 81.
