Description

Technical Field

[0001] The utility model relates to the technical field of new energy shared charging, and in particular to an intelligent robot automatic energy replenishment device suitable for new energy charging. Background Art

[0002] With the rapid popularization and development of the new energy electric vehicle industry, how to quickly and conveniently recharge electric vehicles has become a bottleneck factor restricting the rapid and sustainable development of the entire new energy industry. In response to the common fixed, one-pile-per-parking-space charging pile model on the market, a new "shared" charging model has begun to emerge in the charging industry.

[0003] For example, Chinese invention patent CN117656906A discloses a shared charging system for new energy vehicles. When a gasoline vehicle occupies a charging space or an electric vehicle occupies the space for an extended period of time, the control system instructs the transport robot to move the charging distribution box connected to the pile foundation fixed charging seat of this parking space to electrically connect it to the pile foundation fixed charging seat of other parking spaces, so that the pile foundation fixed charging seat of the occupied parking space no longer occupies the total capacitance of the power grid, thereby solving the problems of gasoline vehicles occupying spaces, electric vehicles occupying spaces for an extended period of time, and the limited total capacitance of the power grid.

[0004] The handling robot needs to be charged and recharged during operation. The traditional way of recharging is to use special facilities for fixed-point charging. The charging path does not overlap with the normal working path and is labor-intensive. The robot needs to be recharged and recharged for a long time at a time, which is time-consuming. The charging facilities are large in structure, take up space, and are inconvenient to use. Utility Model Content

[0005] In view of the defects in the prior art, the utility model provides an intelligent robot automatic energy replenishment device suitable for new energy charging, so as to solve the problem that charging of mobile robots in the existing new energy vehicle shared charging system is labor-consuming and time-consuming.

[0006] The utility model provides an intelligent robot automatic energy replenishment device suitable for new energy charging, comprising a mobile robot capable of moving on a walking track, a plurality of new energy vehicle charging piles distributed along the walking track, and an energy replenishment component;

[0007] The energy replenishment component comprises:

[0008] A fixed charging connector, which is installed on a fixed socket of a distribution box of a new energy vehicle charging pile, and is provided with a first positive connection contact and a first negative connection contact, and the first positive connection contact and the first negative connection contact are externally connected to the positive and negative electrodes of a charging power source;

[0009] A mobile charging connector, which is installed on the telescopic positioning guide mechanism of the mobile robot. A second positive connection contact and a second negative connection contact are provided on the mobile charging connector. The second positive connection contact and the second negative connection contact are respectively connected to the power battery of the mobile robot through wires. When the telescopic positioning guide mechanism of the mobile robot aligns the charging distribution box and pushes it into the distribution box fixed socket of the new energy vehicle charging pile, the first positive connection contact is connected to the second positive connection contact, and the first negative connection contact is connected to the second negative connection contact.

[0010] Furthermore, the first positive connection contact is a positive contact pin female head arranged at the front end of the fixed charging connector, the first negative connection contact is a negative contact pin female head arranged at the front end of the fixed charging connector, the second positive connection contact is a positive contact pin male head arranged at the front end of the mobile charging connector, and the second negative connection contact is a negative contact pin male head arranged at the front end of the mobile charging connector.

[0011] Furthermore, the positive electrode contact pin male head and the negative electrode contact pin male head both use spring-retractable contact pins.

[0012] Furthermore, both the fixed charging connector and the movable charging connector adopt nylon seats.

[0013] Furthermore, the energy replenishment component also includes:

[0014] A positioning and extending detection plate is installed on a fixed socket of a distribution box of a new energy vehicle charging pile;

[0015] The positioning and extending into position detection switch is installed on the telescopic positioning guide mechanism of the mobile robot. When the first positive connection contact and the first negative connection contact on the fixed charging connector are respectively connected with the second positive connection contact and the second negative connection contact on the mobile charging connector, the positioning and extending into position detection plate triggers the positioning and extending into position detection switch, so that the positioning and extending into position detection switch triggers a signal to control the telescopic positioning guide mechanism to stop the action.

[0016] Furthermore, a first positioning guide is provided on the fixed socket of the distribution box of the new energy vehicle charging pile, and a second positioning guide that can cooperate with the first positioning guide is provided at the front end of the telescopic positioning guide mechanism of the mobile robot.

[0017] Furthermore, the first positioning guide member is a guide hole, and the second positioning guide member is a travel positioning guide pin.

[0018] Furthermore, two guide holes and two travel positioning guide pins are respectively symmetrically arranged on the left and right.

[0019] The beneficial effects of the utility model are embodied in:

[0020] The utility model combines the specific charging action of the mobile robot with the automatic walking alignment action. The mobile charging connector is fixed on the positioning and telescopic guide mechanism of the mobile robot. When the mobile robot executes the charging operation instruction, the mobile robot walks to the designated charging parking space, and the telescopic positioning guide mechanism performs an extending and guiding action, which will drive the mobile charging connector to extend forward. When the second positive connection contact and the second negative connection contact on the mobile charging connector are respectively in contact with the first positive connection contact and the first negative connection contact on the fixed charging connector, the charging circuit of the mobile robot is turned on, and the charger can charge and replenish the power battery of the mobile robot through the turned-on circuit.

[0021] The mobile robot takes about three minutes to plug and unplug the charging distribution box. The charger can instantly recharge the power battery during this period. When the plug and unplug action is completed and the mobile robot's telescopic positioning guide mechanism retracts, charging ends automatically.

[0022] Therefore, the mobile robot of the present application can complete instant charging and energy replenishment while performing normal scheduling and handling of the charging distribution box. The power battery of the mobile robot will not be in a working power feeding state, and there is no need to perform additional charging and energy replenishment action processes, which improves the working efficiency of the robot. In addition, the present application installs the fixed charging connector on the fixed socket of the distribution box of the new energy vehicle charging pile, and the mobile charging connector is installed on the telescopic positioning guide mechanism of the mobile robot. The telescopic positioning guide mechanism of the mobile robot itself can be used to achieve the docking of the fixed charging connector and the mobile charging connector. The entire mechanism has a compact structure, does not require the addition of a special motion mechanism, and the design is reasonable and ingenious. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0030] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0031] like Figure 1-Figure 4 As shown, an embodiment of the utility model provides an intelligent robot automatic energy replenishment device suitable for new energy charging, including a mobile robot 100 capable of moving on a walking track, a plurality of new energy vehicle charging piles 200 distributed along the walking track, and an energy replenishment component.

[0032] The mobile robot 100 is provided with a telescopic positioning guide mechanism 110, which is used to carry the charging distribution box and can be automatically extended and retracted. The new energy vehicle charging pile 200 is provided with a distribution box fixed socket 210. When using the new energy vehicle charging pile 200 for charging, the charging distribution box needs to be moved and pushed into the distribution box fixed socket 210 by the mobile robot 100 until the charging distribution box is docked with the fixed charging seat on the new energy vehicle charging pile 200. Only then can the charging control circuit of the new energy vehicle charging pile 200 be connected to realize the charging of the new energy vehicle. This technology is a prior art and is not an invention improvement point of the present application, so it will not be elaborated here.

[0033] The charging assembly includes a fixed charging connector 300 and a mobile charging connector 400 .

[0034] Reference Figure 2The fixed charging connector 300 is installed on the distribution box fixed socket 210 of the new energy vehicle charging pile 200. The fixed charging connector 300 is provided with a first positive connection contact and a first negative connection contact. The first positive connection contact and the first negative connection contact are connected to the positive and negative poles of the external charging power source.

[0035] Reference Figure 4 The mobile charging connector 400 is installed on the telescopic positioning guide mechanism 110 of the mobile robot 100. The mobile charging connector 400 is provided with a second positive connection contact and a second negative connection contact. The second positive connection contact and the second negative connection contact are respectively connected to the power battery of the mobile robot 100 through wires.

[0036] When the telescopic positioning guide mechanism 110 of the mobile robot 100 aligns the charging distribution box and pushes it into the distribution box fixing socket 210 of the new energy vehicle charging pile 200, the first positive connection contact is connected with the second positive connection contact, and the first negative connection contact is connected with the second negative connection contact.

[0037] In this embodiment, the first positive connection contact is preferably a positive contact pin female head 310 provided at the front end of the fixed charging connector 300, and the first negative connection contact is specifically a negative contact pin female head 320 provided at the front end of the fixed charging connector 300. The second positive connection contact is preferably a positive contact pin male head 410 provided at the front end of the mobile charging connector 400, and the second negative connection contact is specifically a negative contact pin male head 420 provided at the front end of the mobile charging connector 400. The positive / negative contact pin male head and the positive / negative contact pin female head are easy to install, and only need to be inserted and fixed on an insulating fixed block.

[0038] The positive contact pin male head 410 and the negative contact pin male head 420 in this embodiment both use spring-retractable contact pins. The spring-retractable contact pins are retractable, which can ensure that the positive / negative contact pin male head and the positive / negative contact pin female head can fully and effectively contact each other after being pressed together, thereby ensuring normal current conduction during charging.

[0039] The fixed charging connector 300 and the mobile charging connector 400 in this embodiment both use nylon seats. The main function of the nylon seats is to install the positive / negative male contact pins and the positive / negative female contact pins for fixed energy replenishment charging, and also to play an insulating protection role when the charging current passes through.

[0040] Reference Figure 2 and Figure 4The energy charging component also includes a positioning and extending in place detection plate 500 and a positioning and extending in place detection switch 600. The positioning and extending in place detection plate 500 is installed on the distribution box fixed socket 210 of the new energy vehicle charging pile 200. The positioning and extending in place detection switch 600 is installed on the telescopic positioning guide mechanism 110 of the mobile robot 100. When the first positive connection contact and the first negative connection contact on the fixed charging connector 300 are respectively connected with the second positive connection contact and the second negative connection contact on the mobile charging connector 400, the positioning and extending in place detection plate 500 triggers the positioning and extending in place detection switch 600, so that the positioning and extending in place detection switch 600 triggers a signal to control the telescopic positioning guide mechanism 110 to stop the action. The purpose of the positioning and extending in place detection switch 600 in this embodiment is to detect whether the telescopic positioning guide mechanism 110 is fully extended. When the positioning and extending in place detection switch 600 contacts the positioning and extending in place detection plate 500, the positioning and extending in place detection switch 600 can feedback a signal to the control system to control the telescopic positioning guide mechanism 110 to stop moving. At this time, it can ensure that the positive / negative contact pin male head is in full and effective contact with the positive / negative contact pin female head.

[0041] Continue to refer to Figure 2 and Figure 4 A first positioning guide is provided on the distribution box fixed socket 210 of the new energy vehicle charging pile 200. The first positioning guide is preferably a guide hole 211. The front end of the telescopic positioning guide mechanism 110 of the mobile robot 100 is provided with a second positioning guide that can cooperate with the first positioning guide for positioning and guiding. The second positioning guide is preferably a walking positioning guide pin 111. In this embodiment, two guide holes 211 and two walking positioning guide pins 111 are respectively symmetrically arranged on the left and right.

[0042] When the telescopic positioning guide mechanism 110 is pushed out, the travel positioning guide pin 111 is inserted into the guide hole 211 on the fixed seat, which can position the docking of the telescopic positioning guide mechanism 110 and the distribution box fixed socket 210, thereby ensuring that the positive / negative contact pin male head and the positive / negative contact pin female head can be accurately docked.

[0043] The utility model combines the specific charging action of the mobile robot 100 with the automatic walking alignment action. The mobile charging connector 400 is fixed on the positioning and telescopic guide mechanism of the mobile robot 100. When the mobile robot 100 is executing the charging operation instruction, the mobile robot 100 walks to the designated charging parking space, and the telescopic positioning guide mechanism 110 performs an extending and guiding action, which will drive the mobile charging connector 400 to extend forward. When the second positive connection contact and the second negative connection contact on the mobile charging connector 400 are respectively in contact with the first positive connection contact and the first negative connection contact on the fixed charging connector 300, the charging circuit of the mobile robot 100 is turned on, and the charger can charge and replenish the power battery of the mobile robot 100 through the turned-on circuit.

[0044] The mobile robot 100 takes about three minutes to plug and unplug the charging distribution box. The charger can instantly recharge the power battery during this period. When the plug and unplug action is completed and the telescopic positioning guide mechanism 110 of the mobile robot 100 is retracted, charging ends automatically.

[0045] Therefore, the mobile robot 100 of the present application can complete instant charging and energy replenishment while performing normal scheduling and handling of the charging distribution box. The power battery of the mobile robot 100 will not be in a working power feeding state, and there is no need to perform additional charging and energy replenishment action processes, thereby improving the working efficiency of the robot. In addition, the present application installs the fixed charging connector 300 on the distribution box fixed socket 210 of the new energy vehicle charging pile 200, and the mobile charging connector 400 is installed on the telescopic positioning guide mechanism 110 of the mobile robot 100. The telescopic positioning guide mechanism 110 of the mobile robot 100 itself can be used to achieve the docking of the fixed charging connector 300 and the mobile charging connector 400. The entire mechanism has a compact structure, does not require the addition of a special motion mechanism, and is reasonably and cleverly designed.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
