Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of AGV brush plate, in particular to an AGV brush plate with end outlet. BACKGROUND

[0002] When the AGV trolley is charging, the AGV brush block slides onto the AGV brush plate through the right slope, then the AGV brush block makes contact through the action of the spring, and then charges, after being fully charged, the AGV brush block retreats from the right side.

[0003] In the AGV trolley ground charging system, when the ground charging brush plate is not pre-buried in the ground, single-end outlet is adopted, and the cable needs to be bent 90° during installation. This is because the ground charging brush plate usually needs to maintain a specific positional relationship with the ground to realize effective docking with the charging part of the AGV trolley. After the cable is drawn out from the single end of the brush plate, in order to reasonably layout the cable, avoid affecting the normal driving of the AGV trolley, and meet the layout requirements of the overall charging system, it needs to be bent 90° to fit the ground or related installation structure. Just like arranging the electric wire in our home, in order to let the electric wire not to scatter randomly, affect the appearance and safety, it will be arranged according to a certain direction and angle. However, due to the hard texture of the cable, it is difficult to bend 90°, which is like bending a hard bamboo pole. The hard cable has high rigidity and anti-deformation ability due to its internal material and structure, so forcibly bending not only needs to consume a lot of effort, but also easily causes damage to the internal wires of the cable and the rupture of the insulation layer, affecting the service life and charging performance of the cable, and further affecting the stability and reliability of the entire ground charging system.

Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Please refer to Figures 1-7The utility model provides an AGV brush plate of terminal outgoing line, which comprises a brush block 1 arranged on an AGV, a brush plate 2 arranged on the ground, a wiring mechanism 3, a slot is formed in the side of the brush plate 2, and the slot is used for mounting the wiring mechanism 3, a contact mechanism 4 arranged on the brush plate 2, and a buffer mechanism 5 arranged at the bottom of the contact mechanism 4. The wiring mechanism 3 comprises an access line 31, a sealing plug 32 arranged on the access line 31, the sealing plug 32 is inserted into the brush plate 2, the access line 31 is connected with a connecting ring 33, the bottom of the connecting ring 33 is connected with a positioning bolt 34, the positioning bolt 32 fixes the connecting ring 33 on the brush plate 2, the top of the connecting ring 33 is provided with a connecting column 35, the outer wall of the connecting column 35 is slidably connected with a connecting cap 36, a spring 37 is arranged between the connecting cap 36 and the connecting ring 33, and the principle of the wiring mechanism 3 is to realize stable, reliable and buffered electrical connection between the access line 31 and the brush plate 2. The sealing plug 32 on the access line 31 is inserted into the brush plate 2, thereby achieving primary connection and sealing effect, preventing external dust, water vapor and the like from entering and affecting the stability of electrical connection. The connecting ring 33 is fixed on the brush plate 2 through the positioning bolt 34, thereby providing a stable basis for subsequent connection, ensuring that the position of the access line 31 is fixed and avoiding loose contact. The spring 37 is arranged between the connecting column 35 at the top of the connecting ring 33 and the connecting cap 36 slidably connected with the outer wall, the spring 37 ensures that the connecting cap 36 tightly contacts the contact mechanism 4 for power supply, the contact mechanism 4 contacts the brush block 1 for power supply, the electrical energy of the access line 31 can be transmitted to the contact mechanism 4 in sequence through the connecting ring 33, the connecting column 35 and the connecting cap 36, and then the contact mechanism 4 contacts the brush block 1 arranged on the AGV, thereby finally realizing the function of power supply for the AGV, and the wiring mechanism 3 is used for directly connecting the access line 31 with the brush plate 2 without bending, the contact mechanism 4 is rotated when contacting the brush block 1, thereby avoiding damage caused by friction, and the buffer mechanism 5 buffers when the contact mechanism 4 is impacted.

[0033] One end of the spring 37 is fixedly connected to the connecting cap 36, and the other end of the spring 37 is fixedly connected to the connecting ring 33.

[0034] The contact mechanism 4 comprises a conductive plate 41, the conductive plate 41 is fixedly connected with a support frame 42, the inner wall of the support frame 42 is rotatably connected with two symmetrical transmission rollers 43, the two transmission rollers 43 are drivingly connected with a transmission track 44, the inner wall of the support frame 42 is arrayed with a positioning roller 45, the conductive plate 41 is the core conductive component of the whole contact mechanism 4, and the electric energy is transmitted to the conductive plate 41 through the wiring mechanism 3, thereby providing an electric energy source for the subsequent power supply process. The inner wall of the support frame 42 is rotatably connected with two symmetrical transmission rollers 43, and the two transmission rollers 43 are drivingly connected through the transmission track 44. When the AGV trolley drives the brush block 1 to abut against the transmission track 44 on the top of the brush plate 2, the transmission track 44 drives the transmission roller 43 to rotate, the rotation of the transmission track 44 avoids the static friction of the contact position of the brush block 1 and the transmission track 44, avoids excessive wear, prolongs the service life of the contact mechanism 4 and the brush block 1, and the positioning roller 45 arrayed on the inner wall of the support frame 42 can position and guide the transmission track 44. Ensure that the transmission track 44 maintains the correct position and tension during operation, prevent it from running off or relaxing, and provide power transmission.

[0035] The buffering mechanism 5 comprises a magnetic hollow column 51 and a containing groove 55, the containing groove 55 is opened on the inner wall of the brush plate 2, the magnetic hollow column 51 is fixedly connected on the inner wall of the containing groove 55, a magnetic ring 52 is slidably connected on the inner wall of the magnetic hollow column 51, a connecting sleeve 53 is fixedly connected on the top of the magnetic ring 52, a spring 54 is arranged between the connecting sleeve 53 and the containing groove 55, the top of the connecting sleeve 53 is fixedly connected with the conductive plate 41, when the transmission track 44 is not extruded by the brush block 1, the spring 54 is in the stretched state, which drives the connecting sleeve 53 to move upward. Since the top of the connecting sleeve 53 is fixedly connected with the conductive plate 41, the conductive plate 41 also moves upward. At this time, the conductive plate 41 no longer abuts against the connecting cap 36, the electrical connection between the wiring mechanism 3 and the contact mechanism 4 is cut off, so that the contact mechanism 4 is in the power-off state. When the AGV car charges, the AGV car drives the brush block 1 to abut against and extrude the transmission track 44, the transmission track 44 drives the contact mechanism 4 to move downward as a whole. During the downward movement of the contact mechanism 4, the conductive plate 41 extrudes the spring 54 downward. The spring 54 is compressed, and at the same time, the conductive plate 41 abuts against the connecting cap 36 again, the electrical connection between the wiring mechanism 3 and the contact mechanism 4 is restored, so that the contact mechanism 4 is powered on, and the electric energy can be transmitted to the brush block 1 through the conductive plate 41 and the transmission track 44 to supply power to the AGV car. In this process, the spring 54 plays a buffering role, which can absorb the impact force generated when the brush block 1 extrudes the transmission track 44, reduce the damage to the contact mechanism 4 and the wiring mechanism 3, and prolong the service life of the components. When the brush block 1 no longer abuts against the transmission track 44, the spring 54 releases the elastic potential energy, drives the connecting sleeve 53 and the magnetic ring 52 to move upward. In this process, the magnetic attraction between the magnetic ring 52 and the magnetic hollow column 51 will generate a certain resistance to the upward movement of the magnetic ring 52, so that the connecting sleeve 53 and the conductive plate 41 move upward slowly, avoiding the violent collision caused by the excessive elastic restoring force of the spring 54, further protecting the electrical components, and ensuring that the contact mechanism 4 can smoothly return to the power-off state.

[0036] One end of the spring 54 is fixedly connected on the inner wall of the containing groove 55, the other end of the spring 54 is fixedly connected on the connecting sleeve 53, the sealing plug 32 is made of rubber material, and an annular sealing groove is arranged on the surface of the sealing plug 32 to enhance the sealing effect of the plug-in part of the brush plate 2, a sealing rubber ring is arranged on the plug-in part of the brush plate 2 corresponding to the sealing plug 32 to further enhance the sealing performance, the surface of the transmission roller 43 is provided with anti-skid patterns to enhance the friction between the transmission track 44, the transmission track 44 is made of metal material and has good conductivity and wear resistance, the conductive plate 41 and the support frame 42 are connected by bolts, which is convenient for disassembly and maintenance, the magnetic hollow column 51 is made of permanent magnetic material, and a wear-resistant coating is arranged on the surface of the magnetic ring 52 to prolong the service life of the magnetic ring 52, and an inclined surface is opened on the brush plate 2.

[0037] In summary, the AGV brush plate of the outlet line is stably arranged on the ground to ensure its fixed and horizontal position. The slope on the brush plate 2 can be reasonably oriented according to the actual site and the driving route of the AGV trolley to ensure accurate alignment when the AGV trolley drives over the brush plate 2 and smoothly performs the charging operation.

[0038] The access line 31 is inserted through the sealing plug 32, and the sealing plug 32 is inserted into the corresponding hole of the brush plate 2. Since the sealing plug 32 is made of rubber material and has an annular sealing groove on the surface, and the brush plate 2 has a sealing rubber ring at the joint, it can effectively prevent dust, water vapor and other external factors from entering, thereby enhancing the sealing performance. This can avoid the erosion of dust and water vapor on the electrical connection part, reduce the probability of contact failure, short circuit and other faults, improve the reliability and service life of the wiring mechanism 3, and ensure the stable operation of the entire charging system.

[0039] The connecting ring 33 is fixedly connected with the access line 31, and the connecting ring 33 is fixed on the brush plate 2 by the positioning bolt 34 to ensure the fixation of the access line 31 and avoid loosening caused by poor contact. One end of the spring 37 is fixed on the connecting cap 36, and the other end is fixed on the connecting ring 33. The connecting cap 36 can slide freely on the connecting column 35. Since the wiring mechanism 3 is installed in the groove on the side of the brush plate 2, on the one hand, the side groove can provide physical protection to reduce the risk of cable being collided or scratched by external factors, avoid damage to the cable due to external force, ensure stable charging, and reduce the probability of system failure. On the other hand, such a layout can reduce the need for cable bending, and even avoid bending, directly connecting the cable to the wiring mechanism 3, solving the problems of laborious bending and easy damage, ensuring stable transmission of electric energy, and improving the stability and reliability of the AGV ground charging brush plate system. The design of the side groove not only protects the cable, but also optimizes the connection mode of the cable, reduces the charging interruption or instability caused by cable problems, and makes the entire charging system more stable and efficient.

[0040] When the AGV trolley needs to be charged, it drives over the brush plate 2 so that the brush block 1 abuts against the top of the driving track 44 of the brush plate 2. The friction between the brush block 1 and the driving track 44 drives the driving track 44 to move, and then the driving roller 43 rotates, avoiding static friction between the brush block 1 and the driving track 44, reducing excessive wear, and prolonging the service life of the contact mechanism 4 and the brush block 1. This design reduces the wear between components, reduces the frequency of replacing components, saves maintenance costs, and also ensures the stability and continuity of the charging process.

[0041] When the brush block 1 extrudes the transmission track 44, the contact mechanism 4 will be driven to move downward as a whole. When the contact mechanism 4 moves downward, the spring 54 is compressed, and the electrically conductive plate 41 recontacts with the connecting cap 36, restoring the electrical connection between the wiring mechanism 3 and the contact mechanism 4, so that the contact mechanism 4 is electrified. At this time, the electric energy of the access wire 31 is transmitted to the brush block 1 through the connecting ring 33, the connecting column 35, the connecting cap 36, the electrically conductive plate 41, and the transmission track 44, and finally powers the AGV car. In this process, the spring 54 acts as a buffer to absorb the impact force generated when the brush block 1 extrudes the transmission track 44, reducing damage to the contact mechanism 4 and the wiring mechanism 3. The buffering effect of the spring 54 protects the contact mechanism 4 and the wiring mechanism 3, avoids damage to the components due to excessive impact force, and further improves the reliability and stability of the entire charging system.

[0042] When the AGV car finishes charging and leaves, the brush block 1 no longer contacts the transmission track 44, and the spring 54 releases the elastic potential energy, driving the connecting sleeve 53 and the magnetic ring 52 to move upward. The magnetic attraction between the magnetic ring 52 and the magnetic hollow column 51 will generate a certain resistance to the upward movement of the magnetic ring 52, causing the connecting sleeve 53 and the electrically conductive plate 41 to move upward slowly.

[0043] After the electrically conductive plate 41 moves upward, it no longer contacts the connecting cap 36, cutting off the electrical connection between the wiring mechanism 3 and the contact mechanism 4, so that the contact mechanism 4 is in a de-energized state. At the same time, this slow moving method avoids the generation of violent collisions due to the excessive elastic restoring force of the spring 54, further protecting the electrical components and ensuring that the contact mechanism 4 can smoothly return to the de-energized state. The magnetic attraction and slow movement design protects the electrical components, avoids damage caused by violent collisions, prolongs the service life of the components, and ensures that the charging system can safely and smoothly switch to the de-energized state after charging is completed.
