[0033] With the continuous advancement and improvement of the technology of automated guided vehicles (AGVs) and intelligent logistics vehicles, the market demand for AGV performance has gradually increased, especially the demand for endurance. However, due to the space limitations of the AGV itself, its battery capacity often cannot meet the needs of long-term operation. Therefore, in order to ensure that the AGV can continue to work efficiently, it is necessary to use an external AGV charger to replenish the energy of its built-in battery. These charging devices can provide AGVs with fast and efficient charging solutions, thereby ensuring that they will not interrupt their missions due to lack of power during long-term operation. With the continuous advancement of technology, the charging speed and intelligence level of AGV chargers are also constantly improving, further improving the work efficiency and reliability of AGV vehicles.

[0034] The AGV charger has many internal parts and a complex structure, which makes it complicated and time-consuming for production personnel to replace, assemble, maintain and overhaul the internal components of the AGV charger. This not only increases the difficulty of the maintenance personnel's work, but also significantly increases the maintenance cost.

[0035] The present invention provides an AGV automatic guided charging device.

[0036] See also Figures 1 to 3In one embodiment of the present invention, the AGV automatic guided charging device includes a shell 1, the shell 1 has a accommodating cavity 11, and one side of the accommodating cavity 11 has a first opening; a main control board module 2, the main control board module 2 is arranged in the accommodating cavity 11; a power supply module 3, the power supply module 3 is arranged in the accommodating cavity 11, and the power supply module 3 is electrically connected to the main control board module 2; and a brush block telescopic module 4, the brush block telescopic module 4 is movably arranged in the accommodating cavity 11, the brush block telescopic module 4 is electrically connected to the main control board module 2, and the brush block telescopic module 4 has a plug-in position extending out of the first opening, and a retracted position moved to the accommodating cavity 11;

[0038] In this embodiment, the housing 1 includes a frame, a first shell and a second shell, and the first shell and the second shell are arranged on opposite sides of the frame, so that a housing cavity 11 is formed inside the housing 1. The other outer wall of the frame away from the outer wall where the first shell and the second shell are located has a first opening connected to the housing cavity 11, and the first opening can be arranged at the lower part of the frame, so that the brush block telescopic module 4 can be aligned with the charging port on the AGV vehicle after extending out of the first opening. The main control board module 2 can be installed with an anti-tilt circuit board for detecting whether the housing 1 is in a dumping state. When the housing 1 is tilted or dumped due to improper telescopic position of the brush block telescopic module 4 or other special circumstances, the anti-tilt circuit board will feedback a signal to the power module 3 after detection and automatically cut off the power supply to avoid electrical short circuit and spark generation in the main control board module 2 or the power module 3, thereby preventing fire or electric shock accidents and improving the safety performance of the present application. The power module 3 is used for voltage and current regulation, so that the current output by the brush block telescopic module 4 can better meet the requirements of the AGV vehicle battery. The brush block telescopic module 4 is used to partially extend out of the first opening and move to the plug-in position, so that the brush block telescopic module 4 is plugged into the charging port on the AGV vehicle for charging. After charging is completed, the brush block telescopic module 4 moves to the retracted position in the accommodating chamber 11. The internal components of the present application are modularly designed so that each module can be independently installed and disassembled, so that the main control board module 2, the power module 3 and the brush block telescopic module 4 can be installed in the accommodating chamber 11 of the housing 1 in a hierarchical manner according to the layout requirements, thereby facilitating the installation of each module and improving the production efficiency of the present application. In addition, when any module in the present application fails or is damaged, the damaged module can be removed and replaced separately, thereby simplifying the maintenance process and significantly reducing the maintenance cost of the AGV charging device during subsequent use. The present application sets up a main control board module 2, a power supply module 3 and a brush block retractable module 4 so that the operator can input relevant instructions to the main control board module 2 through external operation buttons, so that the main control board module 2 can control the power supply module 3 to adjust the external current according to the instruction signal, and so that the main control board module 2 can control the brush block retractable module 4 to extend out of the plug-in position of the first opening or move to the retracted position in the accommodating cavity 11 according to the instruction signal, thereby improving the degree of automation of the present application.

[0039] In this embodiment, the AGV automatic guided charging device also includes a lifting module 6, which includes a mounting seat 61, a second driving member and a transmission member 62. The transmission member 62 can be set as a screw, and the transmission member 62 can be set as a plurality. The second driving member can be set in accordance with the number of the transmission members 62, and the second driving member drives the connection transmission member 62 one by one. It should be noted that the second driving member is not marked in the drawings of the specification. Multiple transmission members 62 are threadedly connected to the bottom of the housing 1 at intervals, and the other ends of the multiple transmission members 62 are connected to the mounting seat 61 at intervals. The second driving member can be set as a driving motor or a driving motor that can drive the transmission member 62 to rotate, so that the second driving member can drive the transmission member 62 to rotate to drive the housing 1 to rise and fall relative to the mounting seat 61, thereby adjusting the height of the brush block 21 from the ground, so that the present application can adapt to the charging port of AGV vehicles of different heights. Preferably, the transmission member 62 can be set as four, and the four transmission members 62 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.

[0040] like Figure 1 and Figure 2 As shown, in this embodiment, the shell 1 includes a first base 12 and a first mounting bracket 13, the main control board module 2 includes a circuit board 21, the first base 12 is installed in the accommodating cavity 11, the first mounting bracket 13 is installed on the first base 12, and the circuit board 21 is arranged in the first mounting bracket 13.

[0041] In this embodiment, the first base 12 is detachably connected to the inner wall of the accommodating cavity 11, and the first mounting bracket 13 is detachably mounted on the first base 12. The first base 12 cooperates with the first mounting bracket 13 to form a first mounting layer for conveniently mounting the main control board module 2. When the main control board module 2 is damaged as a whole, the first base 12 or the first mounting bracket 13 can be disassembled to remove the main control board module 2 as a whole or to disassemble the relevant damaged parts in the main control board module 2, so as to facilitate the replacement of intact parts. The main control board module 2 also includes circuit parts, which can be installed on the first base 12, and the circuit board 21 is installed in the first mounting bracket 13. By disassembling the first base 12 or the first mounting bracket 13, the circuit parts or the circuit board 21 can be correspondingly disassembled, thereby further facilitating the removal of the circuit board 21 or the circuit parts from the housing 1; when replacing or producing, it is only necessary to install the first mounting bracket 13 with the intact circuit board 21 or the first base 12 with the intact circuit parts into the accommodating cavity 11, thereby improving the production efficiency of the present application and reducing the subsequent maintenance cost of the present application.

[0042] like Figure 1 , Figure 2 and Figure 5As shown, in this embodiment, the shell 1 also includes a second mounting bracket 14, the power module 3 includes a mounting shell 31, a heat dissipation component 32 and an electrical component 33 arranged at one end of the mounting shell 31, the second mounting bracket 14 is connected to the first mounting bracket 13, and the second mounting bracket 14 has a mounting cavity, and the mounting shell 31, the heat dissipation component 32 and the electrical component 33 are all arranged in the mounting cavity.

[0043] In this embodiment, the second mounting bracket 14 is detachably connected to the first mounting bracket 13 to form a second mounting layer for conveniently mounting the power module 3. The second mounting bracket 14 has a mounting cavity, so that the mounting housing 31, the heat dissipation assembly 32 and the electrical component 33 are all conveniently mounted in the mounting cavity. When the power module 3 is damaged, the second mounting bracket 14 can be disassembled to remove the power module 3 as a whole from the accommodating cavity 11, and then the intact power module 3 can be mounted on the first mounting bracket 13, so as to facilitate the maintenance of the power module 3.

[0044] In this embodiment, in order to facilitate the overall installation of the power module 3 in the installation cavity, the power module 3 is provided to include an installation shell 31 for installation in the installation cavity, and the heat dissipation component 32 and the electrical component 33 are both arranged in the installation shell 31. By removing the installation shell 31 from the installation cavity, it is convenient to remove the power module 3 as a whole from the installation cavity, and then it is convenient to install the intact power module 3 as a whole into the installation cavity.

[0045] like Figure 1 and Figure 2 As shown, in this embodiment, the AGV automatic guided charging device further includes a connector 5 , and the electrical component 33 is electrically connected to the electrical component 33 via the connector 5 .

[0046] In this embodiment, the connector 5 can be configured as a conductive connector such as a copper bar or an aluminum block, and the connector 5 can be configured as multiple pieces, and the multiple copper bars are also used to fix the wires connected between the electrical component 33 and the circuit component. Multiple copper bars are connected in sequence, and one end of one copper bar is connected to the electrical component 33, and one end of another copper bar is connected to the circuit board 21. The second mounting bracket 14 is detachably connected to the first mounting bracket 13, so that the power module 3 is located above or below the main control board module 2, thereby reducing the distance between the electrical component 33 and the circuit component, thereby reducing the number of connectors 5 used.

[0047] like Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the power supply modules 3 are provided in two, and the two power supply modules 3 are arranged in the installation cavity at intervals.

[0048] In this embodiment, in order to further enhance the scope of application and flexibility of the present application, the power supply module 3 can be set to two, and the two power supply modules 3 are spaced apart in the installation cavity to ensure the stability and redundancy of the system. The present application can flexibly choose to use one or two power supply modules 3 according to the different battery capacities used by the AGV vehicle. When the battery capacity is large, two power supply modules 3 can be enabled to provide greater power support; when the battery capacity is small, only one power supply module 3 can be used to save costs, thereby increasing the scope of application of the power supply module 3, and can be adjusted according to actual needs, thereby ensuring the efficient operation of the present application under different circumstances.

[0049] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the shell 1 also includes a third mounting bracket 15, the brush block telescopic module 4 includes a brush block 21 and a first driving member 42, the first driving member 42 drives and connects the brush block 21, the third mounting bracket 15 includes a connecting frame 151, the connecting frame 151 is arranged on the bottom wall of the accommodating cavity 11, and the first driving member 42 is arranged on the connecting frame 151.

[0050] In this embodiment, the brush block telescopic module 4 further includes a guide assembly 44 disposed on at least one side of the first driving member 42 along the moving direction of the brush block 21. By disposing the connecting frame 151 on the bottom wall of the accommodating chamber 11, and by arranging the first driving member 42 and the guide assembly 44 on the connecting frame 151, the stability of the movement of the brush block telescopic module 4 is improved, so that the brush block 21 is suspended in the accommodating chamber 11 and aligned with the first opening, thereby making it easier for the first driving member 42 to drive the brush block 21 to move in the accommodating chamber 11. By arranging the guide assembly 44 to connect the brush block 21, the extension direction of the guide assembly 44 is consistent with the driving direction of the first driving member 42, and the guide assembly 44 can limit the brush block 21 to move linearly in the direction close to or away from the first opening, thereby guiding the brush block 21 to extend or retract more accurately from the first opening. In order to improve the stability of the first driving member 42 driving the brush block 21 to move, the guide assembly 44 can be provided on both sides of the first driving member 42.

[0051] like Figure 1 , Figure 3 and Figure 4As shown, in this embodiment, the third mounting bracket 15 further includes a mounting bracket 152 connected to the connecting bracket 151, the mounting bracket 152 includes a fixing portion 1521, and the driving member is installed in the mounting bracket 152 through the fixing portion 1521. The third mounting bracket 15 further includes a mounting member 153, the mounting bracket 152 further includes a frame 1522 covering the connecting bracket 151, the mounting member 153 is arranged on the frame 1522, the brush block telescopic module 4 further includes a first travel switch 43, the first travel switch 43 is installed on the mounting member 153, the frame 1522 has a notch 1523 at one end close to the mounting member 153, and the first travel switch 43 passes through the notch 1523 to abut against the first driving member 42.

[0052] In this embodiment, the mounting frame 152 includes a fixing member for fixing the first driving member 42 and a frame 1522 provided on one side of the fixing member, the fixing member is installed on the side of the connecting frame 151 away from the brush block 21, and the frame 1522 is connected to the fixing member and covered on the connecting frame 151. The guide assembly 44 includes a guide rod 441 and a guide seat 442, the guide rod 441 is connected to the brush block 21, and the guide seat 442 is slidably sleeved on the guide rod 441, and the first driving member 42, the guide rod 441 and the guide seat 442 are respectively installed in the mounting frame 152. When the guide assembly 44 is arranged on both sides of the axial direction of the first driving member 42, the guide seats 442 are slidably sleeved on the guide rod 441 one by one, and the two guide seats 442 are installed on the inner walls of the two sides of the frame 1522, so that the two guide assemblies 44 are respectively arranged on both sides of the first driving member 42, so that it is more convenient to adjust the relative positions between the first driving member 42, the brush block 21 and the guide assembly 44 during the production process, and then the first driving member 42 and the guide assembly 44 are more stably installed on the third mounting bracket 15. The extension direction of the guide rod 441 is the same as the driving direction of the first driving member 42, so that the guide assembly 44 can better guide the brush block 21 to move linearly in the direction close to or away from the first opening, thereby improving the accuracy of the brush block 21 moving to the plug-in position or the retracted position.

[0053] In this embodiment, the first driving member 42 can be set as an electric push rod or a cylinder, so that the first driving member 42 can drive the brush block 21 to move linearly in a direction close to or away from the first opening, so that the brush block 21 can be more accurately plugged into the charging port of the AGV vehicle. When the brush block 21 is in the plug-in position, the brush block 21 is exposed outside the first opening as a whole. When the brush block 21 is in the retracted position, the brush block 21 is stored in the accommodating chamber 11 as a whole, thereby avoiding the brush block 21 being exposed outside the first opening for a long time and causing accidental touch. By setting the AGV automatic guided charging device to also include a first travel switch 43 and a second travel switch 45, the first travel switch 43 and the second travel switch 45 can be respectively arranged on the brush block telescopic module 4. The first travel switch 43 can be set as a roller travel switch, and the contact end of the first travel switch 43 abuts the first driving member 42. When the brush block 21 is in the plug-in position, the contact end of the first travel switch 43 is disconnected from the first driving member 42, and the first travel switch 43 forms a first signal and feeds back to the first driving member 42 to control the first driving member 42 to stop driving the brush block 21. When the brush block 21 is in the retracted position, the contact end of the second travel switch 45 abuts the brush block 21, and the second travel switch 45 forms a second signal and feeds back to the first driving member 42 to control the first driving member 42 to stop driving the brush block 21. The present application adopts a first travel switch 43 and a second travel switch 45 to accurately control the travel of the brush block 21 extending out of the first opening to connect to the charging port of the AGV vehicle and the travel of moving back to the initial position, thereby further improving the accuracy of the brush block 21 being plugged into the charging port of the AGV vehicle, thereby preventing the brush block 21 from colliding with hard obstacles during the extension process, and improving the accuracy of the brush block 21 moving to the initial position in the accommodating cavity 11, thereby avoiding charging abnormalities caused by position deviation of the brush block 21 during the extension and retraction process.

[0054] In this embodiment, the guide rod 441 near the first travel switch 43 is provided with a truncated cone 4411 for the first travel switch 43 to abut against. When the brush block 21 gradually moves to the plug-in position, the contact end of the first travel switch 43 abuts against the truncated cone 4411 and gradually moves along the outer wall of the truncated cone 4411 to the end of the truncated cone 4411 with a smaller inner diameter, thereby disconnecting the contact end of the first travel switch 43 from the guide rod 441. When the brush block 21 starts to move toward the retracted position, the contact end of the first travel switch 43 starts to move from the end of the truncated cone 4411 with a smaller inner diameter and gradually moves along the outer wall of the truncated cone 4411 to the guide rod 441, thereby restoring the contact end of the first travel switch 43 to abut against the guide rod 441. By setting the outer wall of the truncated cone portion 4411 to be an arc surface, the contact end of the first travel switch 43 can better abut against the truncated cone portion 4411, thereby making it easier for the contact end of the first travel switch 43 to disconnect from the guide rod 441 or to resume abutment with the guide rod 441.

[0055] In this embodiment, in order to improve the stability of the connection between the first travel switch 43 and the mounting bracket 152, the first travel switch 43 is installed on the mounting member 153, and the contact end of the first travel switch 43 is arranged to pass through the notch 1523 and abut the guide rod 441, so that the contact end of the first travel switch 43 and the guide rod 441 are on the same horizontal plane, so that the first travel switch 43 can better abut the guide rod 441, and improve the accuracy of the first signal formed by the first travel switch 43. The length of the guide rod 441 can be consistent with the distance that the brush block 21 moves from the retracted position to the plug-in position. Therefore, when the brush block 21 moves to the plug-in position, the contact end of the first travel switch 43 is disconnected from the guide rod 441, so that the first travel switch 43 forms a first signal and feeds it back to the first driving member 42, so that the first driving member 42 stops driving the brush block 21 to move.

[0056] In this embodiment, in order to improve the accuracy of the second signal generated by the second travel switch 45, a first contact portion 451 is provided at one end of the second travel switch 45 close to the protective cover 411, and a second contact portion 4112 corresponding to the first contact portion 451 is provided at one end of the protective cover 411 close to the second travel switch 45. When the brush block 21 moves to the retracted position, the first contact portion 451 abuts against the second contact portion 4112, so that the second travel switch 45 generates a second signal and feeds back to the first driving member 42, so that the first driving member 42 stops driving the brush block 21 to move, thereby preventing the brush block 21 from moving back to the accommodating chamber 11 due to excessive displacement and collision with the third mounting bracket 15 to cause damage.

[0057] In this embodiment, the first contact portion 451 can be set as a cylindrical connecting head, and the second contact portion 4112 can be set as a connecting plate, so as to increase the contact area between the first contact portion 451 and the second contact portion 4112 and avoid poor contact between the first contact portion 451 and the second contact portion 4112.

[0058] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the brush block 21 also includes a protective cover 411, a plug 412 and a buffer portion 413, the plug 412 is arranged in the protective cover 411, the protective cover 411 has a second opening 4111 for exposing the plug 412, and the buffer portion 413 is arranged at the second opening 4111; and / or, the inner side wall of the protective cover 411 is provided with a fireproof layer.

[0059] In this embodiment, in order to prevent the user or the AGV vehicle from accidentally touching the brush block 21 and causing electric shock during the extension and retraction process, the protective cover 411 has a accommodating cavity. By arranging the plug 412 in the accommodating cavity of the protective cover 411 and providing an insulating layer on the outer wall of the protective cover 411, the metal part of the brush block 21 is completely wrapped during the extension and retraction and charging process, and the metal part of the brush block 21 cannot be touched by the outside, thereby enhancing the safety performance of the present application.

[0060] In this embodiment, a fireproof layer may be provided on the inner wall of the accommodating cavity. When the metal part of the brush block 21 accidentally short-circuits and generates sparks, the fireproof layer can prevent the sparks from burning inside the accommodating cavity from the root, thereby further improving the safety performance of the present application.

[0061] In this embodiment, the brush block telescopic module 4 also includes a buffer portion 413, and a connecting portion may be provided at the second opening 4111 of the protective cover 411. The buffer portion 413 has a groove corresponding to the connecting portion, and the connecting portion is inserted in the groove so that the buffer portion 413 is sleeved on the protective cover 411, so that when the brush block 21 is plugged into the charging port of the AGV vehicle, the brush block 21 can buffer the impact force generated by the outer wall of the charging port through the buffer portion 413, thereby avoiding damage to the brush block 21 during the connection and disconnection process with the charging port.

[0062] In this embodiment, the plug 412 is detachably mounted on the protective cover 411, so that the plug 412 can be removed to replace other types of plugs 412, thereby enabling the brush block 21 to adapt to different models of AGV vehicles, thereby improving the compatibility and ease of use of the present application.

[0063] like Figure 6 and Figure 7 As shown, in this embodiment, the shell 1 also includes a first fan 16 and a filter 17. A side wall of the shell 1 close to the main control board module 2 has a third opening. The filter 17 is detachably covered on the outer side wall of the third opening away from the main control board module 2. The first fan 16 is arranged at the third opening, and the main control board module 2 is located on the other side of the first fan 16 away from the filter 17.

[0064] In this embodiment, in order to reduce the impact of dust on the circuit board 21 and to cool the circuit board 21, the first fan 16 is arranged on the inner wall of the third opening so that the first fan 16 faces the circuit board 21, so that the first fan 16 generates negative pressure suction, so that the interior of the accommodating chamber 11 is under negative pressure, so that the dust on the circuit board 21 is sucked into the filter 17 and discharged to the external environment. At the same time, the ambient temperature around the circuit board 21 can be cooled, thereby increasing the service life of the circuit board 21.

[0065] In this embodiment, in order to promptly remove dust from the plug 412 and cool the plug 412, the second fan 7 is arranged on the inner wall of the first opening, and a gap is provided on the side of the protective cover 411 close to the second fan 7, so that the second fan 7 can transport the airflow to the plug 412 through the gap, thereby blowing away the dust on the plug 412, and at the same time can also cool down the ambient temperature around the plug 412.

[0066] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
