[0032] Currently, automatic guided vehicles (AGVs) generally use batteries as their power source. However, once the battery is exhausted, it must be charged to ensure the continued operation of the AGV. At present, the method of charging the battery of the AGV is usually automatic charging, by equipping the AGV with a charging brush plate. In this automatic charging system, the charging brush plate on the AGV will cooperate with the charging brush block 21 on the charger in the charging station to achieve automatic charging.

[0033] However, the telescopic travel limit of the brush block 21 in the existing charging mechanism is not accurate, which can easily cause the brush block 21 to be over-extended or over-retracted during the extension and retraction process and cause damage, thereby affecting the service life of the brush block 21, thereby increasing the subsequent maintenance cost of the existing charging system.

[0034] The present invention provides an AGV intelligent automatic guided charging device.

[0035] See also Figure 1 In one embodiment of the present invention, the AGV intelligent automatic guided charging device includes a housing 1, wherein the housing 1 has a receiving cavity 11, and one side of the receiving cavity 11 has a first opening 111;

[0036] A brush block telescopic module 2, the brush block telescopic module 2 is arranged in the accommodating cavity 11, the brush block telescopic module 2 comprises a brush block 21 and a first driving member 22 drivingly connected to the brush block 21, the brush block 21 has an insertion position extending out of the first opening 111, and a retracted position moving to the accommodating cavity 11; and

[0037] The limit assembly 3 includes a first travel switch 31 and a second travel switch 32, wherein the first travel switch 31 and the second travel switch 32 are electrically connected to the first driving member 22 respectively, wherein the first travel switch 31 is used to generate a first signal when the brush block 21 is in the plug-in position, so that the first driving member 22 receives the first signal and stops driving the brush block 21, and the second travel switch 32 is used to generate a second signal when the brush block 21 is in the retracted position, so that the first driving member 22 receives the second signal and stops driving the brush block 21;

[0038] The technical solution of the present invention adopts a first stroke switch 31 to detect whether the brush block 21 is in the plug-in position during the extension process. When the brush block 21 is in the plug-in position, the first stroke switch 31 can generate a first signal to enable the first driving member 22 to stop driving the brush block 21 to move after receiving the first signal; and adopts a second stroke switch 32 to detect whether the brush block 21 is in the retracted position during the movement into the accommodating cavity 11. When the brush block 21 is in the retracted position, the second stroke switch 32 can generate a second signal to enable the first driving member 22 to stop driving the brush block 21 to move after receiving the second signal, thereby preventing the brush block 21 from colliding with hard obstacles in the running state, thereby reducing the wear and damage of the brush block 21 and extending the service life of the brush block telescopic module 2.

[0039] In this embodiment, the AGV intelligent automatic guided charging device also includes a lifting module 7, which includes a base 71, a second driving member and a transmission member 72. The transmission member 72 can be set as a screw, and the transmission member 72 can be set as a plurality. The second driving member can be set in accordance with the number of the transmission members 72, and the second driving member drives the connection transmission member 72 one by one. It should be noted that the second driving member is not marked in the drawings of the specification. Multiple transmission members 72 are threadedly connected to the bottom of the housing 1 at intervals, and the other ends of the multiple transmission members 72 are connected to the base 71 at intervals. The second driving member can be set as a driving motor or a driving motor that can drive the transmission member 72 to rotate, so that the second driving member can drive the transmission member 72 to rotate to drive the housing 1 to rise and fall relative to the base 71, 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 72 can be set as four, and the four transmission members 72 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] In this embodiment, the first driving member 22 can be set as an electric push rod or a cylinder, so that the first driving member 22 can drive the brush block 21 to move linearly in a direction close to or away from the first opening 111, 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 111 as a whole. When the brush block 21 is in the retracted position, the brush block 21 is stored in the accommodating cavity 11 as a whole, thereby avoiding the brush block 21 being exposed outside the first opening 111 for a long time and causing accidental touch. By setting the limit assembly 3 to include a first travel switch 31 and a second travel switch 32, the first travel switch 31 and the second travel switch 32 can be respectively arranged on the brush block telescopic module 2. The first travel switch 31 can be set as a roller 313-type travel switch, and the contact end of the first travel switch 31 abuts the first driving member 22. When the brush block 21 is in the plug-in position, the contact end of the first travel switch 31 is disconnected from the first driving member 22, and the first travel switch 31 forms a first signal and feeds back to the first driving member 22 to control the first driving member 22 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 32 abuts the brush block 21, and the second travel switch 32 forms a second signal and feeds back to the first driving member 22 to control the first driving member 22 to stop driving the brush block 21. The present application adopts a first travel switch 31 and a second travel switch 32 to accurately control the travel of the brush block 21 extending out of the first opening 111 to connect to the AGV vehicle and the travel 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.

[0041] like Figure 1 , Figure 4 and Figure 5 As shown, in the present embodiment, the brush block telescopic module 2 further includes a bracket 23 and a guide assembly 24 provided on at least one side of the first driving member 22, the bracket 23 includes a connecting frame 231, the connecting frame 231 is provided on the bottom wall of the accommodating cavity 11, the first driving member 22 and the guide assembly 24 are both provided on the connecting frame 231, the guide assembly 24 is connected to the brush block 21, and the guide assembly 24 is used to guide the brush block 21 to move in a direction close to or away from the first opening 111.

[0042] In this embodiment, by arranging the connecting frame 231 on the bottom wall of the accommodating chamber 11, and by arranging the first driving member 22 and the guide assembly 24 on the connecting frame 231, the stability of the movement of the brush block telescopic module 2 is improved, so that the brush block 21 is suspended in the accommodating chamber 11 and aligned with the first opening 111, so that it is more convenient for the first driving member 22 to drive the brush block 21 to move in the accommodating chamber 11. By arranging the guide assembly 24 to connect the brush block 21, the extension direction of the guide assembly 24 is consistent with the driving direction of the first driving member 22, and the guide assembly 24 can limit the brush block 21 to move linearly in the direction close to or away from the first opening 111, thereby guiding the brush block 21 to extend or retract more accurately from the first opening 111. In order to improve the stability of the first driving member 22 driving the brush block 21 to move, the guide assembly 24 can be provided on both sides of the first driving member 22.

[0043] like Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment, the bracket 23 also includes a mounting frame 232 connected to the connecting frame 231, the guide assembly 24 includes a guide rod 241 and a guide seat 242, the guide rod 241 is connected to the brush block 21, the guide seat 242 is slidably sleeved on the guide rod 241, and the first driving member 22, the guide rod 241 and the guide seat 242 are respectively installed in the mounting frame 232.

[0044] In this embodiment, the mounting frame 232 includes a fixing member 2322 for fixing the first driving member 22 and a frame 2323 provided on one side of the fixing member 2322. The fixing member 2322 is installed on the side of the connecting frame 231 away from the brush block 21. The frame 2323 is connected to the fixing member 2322 and is covered on the connecting frame 231. When the guide assembly 24 is arranged on both sides of the axial direction of the first driving member 22, the guide seats 242 are slidably sleeved on the guide rod 241 one by one, and the two guide seats 242 are installed on the inner walls of both sides of the frame 2323, so that the two guide assemblies 24 are respectively arranged on both sides of the first driving member 22, so that it is more convenient to adjust the relative positions between the first driving member 22, the brush block 21 and the guide assembly 24 during the production process, and then the first driving member 22 and the guide assembly 24 are more stably installed on the bracket 23. The extension direction of the guide rod 241 is the same as the driving direction of the first driving member 22, so that the guide assembly 24 can better guide the brush block 21 to move linearly in a direction close to or away from the first opening 111, thereby improving the accuracy of the brush block 21 moving to the plug-in position or the retracted position.

[0045] like Figure 2As shown, in this embodiment, the bracket 23 also includes a connecting piece 233 arranged on the outer side wall of the mounting frame 232, the first travel switch 31 is arranged on the connecting piece 233, the first travel switch 31 includes a main body 311, a connecting arm 312 and a roller 313, the roller 313 is installed at one end of the connecting arm 312, and the other end of the connecting arm 312 is connected to the main body 311, the mounting frame 232 has a notch 2321 on one side close to the connecting piece 233, the roller 313 is penetrated through the notch 2321 and abuts against the guide rod 241, and the roller 313 is used to disengage from the abutment with the guide rod 241 when the brush block 21 is in the plug-in position, so that the first travel switch 31 forms the first signal.

[0046] In this embodiment, in order to improve the stability of the connection between the first travel switch 31 and the mounting bracket 232, the first travel switch 31 is installed on the connecting member 233, and the roller 313 is inserted into the notch 2321 to abut the guide rod 241, so that the roller 313 and the guide rod 241 are on the same horizontal plane, and the roller 313 is better abutted against the guide rod 241, thereby improving the accuracy of the first signal formed by the first travel switch 31. The length of the guide rod 241 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 roller 313 is disconnected from the guide rod 241, so that the first travel switch 31 forms a first signal and feeds it back to the first driving member 22, so that the first driving member 22 stops driving the brush block 21 to move.

[0047] like Figure 4 and Figure 5 As shown, in this embodiment, the brush block 21 includes a plug 211 and a protective cover 212, the plug 211 is connected to the guide rod 241, the protective cover 212 has a accommodating cavity 2121, the plug 211 is arranged in the accommodating cavity 2121, and the outer wall of the protective cover 212 is provided with an insulating layer.

[0048] 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 plug 211 is arranged in the accommodating cavity 2121 of the protective cover 212, and the outer wall of the protective cover 212 is provided with an insulating layer, so that 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.

[0049] In this embodiment, the inner wall of the accommodating cavity 2121 may be provided with a fireproof layer. 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 2121 from the root, thereby further improving the safety performance of the present application.

[0050] In the present embodiment, the brush block telescopic module 2 also includes a buffer portion 8, and the end of the protective cover 212 away from the first driving member 22 may be provided with a connecting portion, and the buffer portion 8 has a groove corresponding to the connecting portion, and the connecting portion is inserted in the groove so that the buffer portion 8 is sleeved on the protective cover 212, 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 8, thereby avoiding damage to the brush block 21 during the connection and disconnection process with the charging port.

[0051] In this embodiment, the plug 211 is detachably mounted on the protective cover 212, so that the plug 211 can be removed to replace other types of plugs 211, 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.

[0052] like Figure 5 As shown, in this embodiment, the second travel switch 32 is arranged on the outer side wall of the mounting frame 232, and the second travel switch 32 includes a main body 321 and a first contact portion 322 arranged on one side of the main body 321. The end of the protective cover 212 close to the second travel switch 32 is provided with a second contact portion 2122 corresponding to the first contact portion 322. When the brush block 21 is in the retracted position, the first contact portion 322 abuts against the second contact portion 2122, so that the second travel switch 32 forms a second signal.

[0053] In this embodiment, in order to improve the accuracy of the second signal formed by the second travel switch 32, a first contact portion 322 is provided on one side of the main body 321 close to the protective cover 212, and a second contact portion 2122 corresponding to the first contact portion 322 is provided on one end of the protective cover 212 close to the second travel switch 32. When the brush block 21 moves to the retracted position, the first contact portion 322 and the second contact portion 2122 abut against each other, so that the second travel switch 32 forms a second signal and feeds back to the first driving member 22, so that the first driving member 22 stops driving the brush block 21 to move, thereby preventing the brush block 21 from moving back to the accommodating chamber 2121 due to excessive displacement and collision with the bracket 23 to cause damage.

[0054] In this embodiment, the first contact portion 322 can be set as a cylindrical connecting head, and the second contact portion 2122 can be set as a connecting plate, so as to increase the contact area between the first contact portion 322 and the second contact portion 2122 and avoid poor contact between the first contact portion 322 and the second contact portion 2122.

[0055] like Figure 3As shown, in this embodiment, the AGV intelligent automatic guided charging device also includes a first fan 4, which is arranged on the inner wall of the first opening 111, and the protective cover 212 has a gap 2123 on one side close to the first fan 4.

[0056] In this embodiment, in order to promptly remove dust from the plug 211 and cool the plug 211, the first fan 4 is disposed on the inner wall of the first opening 111, and a gap 2123 is provided on the side of the protective cover 212 close to the first fan 4, so that the first fan 4 delivers airflow through the gap 2123 to the plug 211, thereby blowing away the dust on the plug 211 and cooling the ambient temperature around the plug 211.

[0057] like Figure 4 and Figure 5 As shown, in this embodiment, the guide rod 241 includes a first guide rod 2411 and a second guide rod 2412, and the first guide rod 2411 and the second guide rod 2412 are respectively arranged on both sides of the first driving member 22, the first guide rod 2411 is located on the side of the second guide rod 2412 close to the first travel switch 31, and the end of the first guide rod 2411 away from the brush block 21 is provided with a frustum portion 2413 for the roller 313 to abut.

[0058] In this embodiment, when the brush block 21 gradually moves to the plug-in position, the roller 313 abuts against the truncated cone 2413 and gradually moves along the outer wall of the truncated cone 2413 to the end of the truncated cone 2413 with a smaller inner diameter, thereby causing the roller 313 to break contact with the first guide rod 2411. When the brush block 21 starts to move toward the retracted position, the roller 313 starts to move from the end of the truncated cone 2413 with a smaller inner diameter and gradually moves along the outer wall of the truncated cone 2413 to the first guide rod 2411, thereby causing the roller 313 to resume contact with the first guide rod 2411. By setting the outer wall of the truncated cone 2413 to be an arc surface, the roller 313 can better abut against the truncated cone 2413, thereby making it easier for the roller 313 to break contact with the first guide rod 2411 or to resume contact with the first guide rod 2411.

[0059] like Figure 1 and Figure 6 As shown, in this embodiment, the AGV intelligent automatic guided charging equipment also includes a power supply module 5 and a main control board module 6, and the power supply module 5 and the main control board module 6 are both arranged in the accommodating cavity 11, and the power supply module 5 is electrically connected to the main control board module 6, and the main control board module 6 is respectively electrically connected to the first driving member 22 and the limit assembly 3.
