[0041] In this embodiment, the reflective column 500 is fixedly connected to the charging box 100 via a connecting plate 510, and a reinforcing connector 520 is connected between the connecting plate 510 and the charging box 100 to improve the stability of the connection between the reflective column 500 and the charging box 100, ensure that the relative positions of the two charging contacts 230 on the reflective column 500 and the charging box body 110 remain unchanged, and improve the recognition accuracy of the robot.

[0043] Generally, two reflective columns 500 are provided to ensure that the robot can accurately locate the charging pile while reducing the equipment cost. The connecting plates 510 of the two reflective columns 500 are fixedly connected to the charging box 100 through a T-shaped reinforcing connector 520. At the same time, the reinforcing connector 520 connects the two connecting plates 510 to maintain the stability of the two connecting plates 510, thereby ensuring the stability of the connection between the reflective column 500 and the charging box 100.

[0044] Combination Figure 2 The charging box 100 includes: a charging box body 110, the upper end of the charging box body 100 is open; a charging box cover 120, the charging box cover 120 is covered at the open end of the charging box 100; a box cover seal 130, the box cover seal 130 is arranged between the charging box body 110 and the charging box cover 120, and the box cover seal 130 can seal the gap between the charging box body 110 and the charging box cover 120; wherein the connecting conductor 210 and the sealing protective member 220 are both installed on the charging box cover 120, so as to facilitate the installation of various accessories of the charging pile while ensuring that the charging box 100 has a sufficient IP protection level.

[0045] Combination Figure 3 A mounting hole 111 is provided at the top of the charging box 100 for the connecting conductor 210 to pass through at intervals. An annular mounting groove 112 is also provided at the top of the charging box 100. The annular mounting groove 112 is concentrically arranged with the mounting hole 111. The annular mounting groove 112 is used to accommodate the lower end protrusion of the sealing protective member 220 to improve the sealing protection performance of the sealing protective member 220.

[0046] It is understandable that handles 140 are usually installed on opposite sides of the charging box body 110 to facilitate the transportation of the charging pile. At the same time, the charging pile is adapted with a control module 150, and the control module 150 is adapted with a display screen, and the control module 150 is installed inside the charging box body 110. The control module 150 is used to control the charging and power-off process of the robot. Specifically, the control module 150 provides feedback on the position of the robot and the connection between the charging port of the robot and the charging pile contacts. When the robot moves to the top of the charging pile and its charging port is connected to the charging contact 230, the control module 150 controls the entire charging pile and starts charging the robot; after the robot is fully charged, the charging control module 150 will disconnect the power supply and end charging. The display screen is installed on the side of the box and is controlled by the control module 150 to display the current working status of the charging pile.

[0047] Recombination Figure 4The sealing protective member 220 is an arc-shaped insulating rubber sleeve, and the charging contact 230 is screwed to the connecting conductor 210; and the upper end of the sealing protective member 220 is fixed to the upper end of the connecting conductor 210 through the charging contact 230, and the lower end of the sealing protective member 220 is fixed to the top of the charging box 100 through the connecting pressure plate 250, so as to ensure that the sealing protective member 220 can play a sealing role while making the connecting conductor 210 and the connecting contact insulated from the charging box 100.

[0048] Specifically, the upper end of the connecting conductor 210 is an external thread, which can be connected and fixed with the internal thread of the charging contact 230. The upper end of the connecting conductor 210 is also provided with a supporting boss 211 for supporting and pressing the sealing protective member 220. The sealing protective member 220 can be set into a funnel shape, and the small hole end of the funnel is sleeved on the connecting conductor 210, and is limited by the supporting boss 211 at the upper end of the connecting conductor 210. After the charging contact 230 is installed, the small hole end of the rubber sleeve is pressed tightly with the supporting boss 211 to achieve the sealing between the connecting conductor 210 and the sealing protective member 220, and the sealing between the charging contact 230 and the sealing protective member 220, thereby sealing the gap between the connecting conductor 210 and the charging box 100 and the gap between the charging contact 230 and the charging box 100. The connecting plate 250 is fixed to the charging box cover 120 by screws to press the open end of the sealing protective member 220, and the sealing protective member 220 is sealed and connected with the charging box 100 to achieve waterproof sealing of the charging box 100. Furthermore, the upper surface of the connecting plate 250 is set as a slope surface, which can effectively avoid water accumulation.

[0049] Combination Figure 6 In this embodiment, the two sides of the charging contact 230 are processed into planes, and the inside is processed into a threaded blind hole. The two side planes are used for installation and removal with tools such as wrenches, and the internal threaded holes are used for fastening and connection with the connecting conductor 210.

[0050] On this basis, the connecting conductor 210 is vertically arranged, and the connecting conductor 210 can slide vertically; a reset spring 240 is also sleeved on the upper end of the connecting conductor 210, and the reset spring 240 is used to drive the connecting conductor 210 to reset, so that when the positive connecting component 200 and the negative connecting component 300 are connected to the corresponding charging port of the robot, the charging contact 230 is in flexible contact with the charging port of the robot, thereby avoiding the robot from being damaged by a strong collision, protecting the charging contact 230, and also ensuring the stability of the connection between the charging contact 230 and the corresponding charging port of the robot, thereby extending the service life of the charging contact 230.

[0051] It can be understood that the present embodiment further includes a mounting base 400, which is disposed in the charging box 100, and the mounting base 400 is insulated and fixedly connected to the charging box 100; a step hole 410 which is larger at the top and smaller at the bottom is disposed in the middle of the mounting base 400, and the connecting conductor 210 is slidably inserted in the step hole 410, and the reset spring 240 is limited by the step hole 410 to ensure that the connecting conductor 210 can slide vertically.

[0052] Combination Figure 7 A limited rotation groove 411 is provided on the side wall of the step hole 410, and the limited rotation groove 213 extends along the axial direction of the step hole 410; a limited rotation protrusion 212 is provided in the middle part of the connecting conductor 210, and the limited rotation protrusion 212 is slidably provided in the limited rotation groove 411, so that when connecting or removing the charging contact 230, the connecting conductor 210 rotates and the operation purpose cannot be achieved.

[0053] In addition, the lower end of the connecting conductor 210 is located outside the lower end of the mounting base 400 , and a limiting protrusion 214 is provided at the lower end of the connecting conductor 210 to prevent the connecting conductor 210 from sliding out of the stepped hole 410 under the action of the return spring 240 .

[0054] Combination Figure 5 , the rotation-limiting protrusion 212 may be a welding part or a structure protruding from the connecting conductor 210. In this embodiment, a cylindrical pin hole is provided at the middle end of the connecting conductor 210, and a cylindrical pin is installed in the cylindrical pin hole to form a limiting protrusion 214 through the cylindrical pin, so that the connecting conductor 210 is prevented from rotating relative to the step hole 410 through the cooperation between the cylindrical pin and the limiting slide groove 213. Similarly, the limiting protrusion 214 may be a welding part or a structure protruding from the connecting conductor 210. In this embodiment, a limiting groove 213 is provided at the lower end of the connecting conductor 210, and an elastic retaining ring is installed in the limiting groove 213 to form the limiting protrusion 214.

[0055] Thus, the elastic retaining ring limits the upward movement of the connecting conductor 210, and the return spring 240 limits the downward movement of the connecting conductor 210. When the robot is charging, the robot charging port is connected to the contact of the charging pile, and the return spring 240 is compressed by the robot's own gravity, so that the robot charging port and the charging contact 230 can achieve flexible contact, avoid collision, protect the contact, and extend the service life of the charging contact 230.

[0056] The connecting conductor 210 is usually made of copper or copper alloy, and a threaded hole is provided on the lower end surface of the connecting conductor 210 to facilitate fixing and connecting the power line by screws.

[0057] It should be noted that, in order to facilitate the installation of the positive electrode connection assembly 200, in the present embodiment, the installation base 400 includes a connection seat 420 and a conductor sleeve 430, and the conductor sleeve 430 is used to fix and limit the connecting conductor 210, and the step hole 410 is the inner hole of the conductor sleeve 430, so that the reset spring 240 is limited by the limiting step at the upper end of the connecting conductor 210 and the step surface of the step hole 410, and the limiting groove 411 inside the conductor sleeve 430 is used for the up and down sliding of the cylindrical pin, and at the same time limits the rotation of the connecting conductor 210, so as to facilitate the installation, disassembly and replacement of the charging contact 230. The conductor sleeve 430 is fixed to the connection seat 420 by means of a connection bolt 432 and a locking nut, and the connection seat 420 is fixed to the charging box cover 120 by means of a fixing screw 422. At the same time, an insulating connection sleeve 433 is provided outside the connection bolt 432, and a first insulating gasket 421 is installed between the conductor sleeve 430 and the connection seat 420, and a second insulating gasket 423 is installed between the connection seat 420 and the charging box cover 120, so that the conductor sleeve 430 is completely insulated from the connection seat 420 and the charging box cover 120, and a short circuit is avoided between the positive and negative charging contacts 230. At the same time, the second insulating gasket 423 can also play a waterproof and sealing role.

[0058] The robot charging pile with quickly replaceable contacts provided in this embodiment is assembled by first fixing the connecting seat 420 and the second insulating gasket 423 on the charging box cover 120 to insulate the connecting seat 420 and the charging box cover 120 through the second insulating gasket 423, and then fixing the conductor sleeve 430, the first insulating gasket 421 and the insulating connecting sleeve 433 on the connecting seat 420 to isolate and insulate the inner bottom surface of the connecting seat 420 and the top surface of the conductor sleeve 430 through the first insulating gasket 421, and the insulating connecting sleeve 433 isolates and insulates the connecting bolt 432 and the connecting seat 420. After the two places are insulated, the conductor sleeve 430, the connecting seat 420 and the charging box cover 120 are completely insulated to avoid a short circuit between the two charging contacts 230. After the conductor sleeve 430 is fixed, the reset spring 240 is sleeved on the lower end of the connecting conductor 210, and then the cylindrical pin is inserted into the cylindrical pin hole in the middle of the connecting conductor 210, and then the connecting conductor 210 is installed into the step through hole of the conductor sleeve 430, so that the cylindrical pin slides into the limiting slide groove 213 inside the conductor sleeve 430, and then the elastic retaining ring is clamped in the groove at the lower end of the connecting conductor 210.

[0059] In summary, the robot charging pile with quickly replaceable contacts provided in this embodiment includes a charging box 100, and a positive electrode connection assembly 200 and a negative electrode connection assembly 300 with the same structure are arranged at intervals on the top of the charging box 100. The positive electrode connection assembly 200 includes a connecting conductor 210 and a sealing protective member 220. The connecting conductor 210 is arranged in the charging box 100, and the lower end of the connecting conductor 210 is used to connect to the charging power source. At the same time, the upper end of the connecting conductor 210 passes through the sealing protective member 220, and the upper end of the connecting conductor 210 is detachably connected to the charging power source. The electrical contacts 230 enable the positive connection component 200 and the negative connection component 300 to be electrically connected to the corresponding charging interface of the robot. At the same time, the sealing protective member 220 seals the gap between the charging contact 230 and the charging box 100 and the gap between the sealing connection conductor 210 and the charging box 100. The charging power supply and control components can be protected by the connection box, and the internal electronic components can be protected from moisture, which effectively extends the service life of the charging pile as a whole. The charging contact 230 is insulated from the charging box 100 to avoid short circuit between the positive and negative electrodes.

[0060] Therefore, in this embodiment, the charging contact 230 is set as a separately replaceable part, and is connected to the connecting conductor 210 through a thread, which is convenient for maintenance and replacement and easy to operate. When the robot needs to be charged, a laser signal will be emitted, and the laser signal will be reflected and sent to the robot through the reflective column. The robot will locate the position of the two charging contacts 230 through the laser signal. When the robot reaches the top of the charging contact 230, the charging contact 230 is squeezed by the robot, so that the two charging contacts 230 are lowered, thereby realizing flexible contact between the charging contact 230 and the robot charging port through the reset spring 240 and the flexible sealing protective member 220, avoiding damage to the contact by strong collision, protecting the contact, and extending the service life of the contact. When the robot charging port and the charging contact 230 are connected, the control module 150 receives a signal that the robot charging port and the charging contact 230 are connected in place, and then controls the charging pile to start charging.

[0061] In summary, in the robot charging pile with quickly replaceable contacts provided in the present embodiment, only the charging contacts 230 of the circuit component part of the charging pile are exposed outside the charging box 100, and the charging contacts 230 are detachably connected to the upper end of the connecting conductor 210. When the charging contacts 230 need to be maintained and replaced, it is only necessary to remove the charging contacts 230 from the upper end of the connecting conductor 210 from the outside of the charging box 100, without the need to remove and replace other components. This has the characteristics of simple maintenance, time-saving, labor-saving and low cost, and can improve the economy of the later maintenance of the robot charging pile.

[0062] In addition, the charging box 100 of this embodiment has good overall sealing and waterproof properties, which can provide moisture-proof protection for internal electronic components. At the same time, all leaking parts are protected, effectively extending the service life.
