Description

Technical Field

[0001] This invention relates to the field of workstation technology, and more specifically, to an automatic charging and water supply workstation. Background Technology

[0002] With the continuous advancement of autonomous driving technology, driverless robots have become an emerging industry, such as driverless cleaning vehicles.

[0003] Currently, when operating outdoors, unmanned robots, such as unmanned sweeping vehicles, still require manual charging and water refilling. This not only increases the workload for manual workers, but also affects work efficiency due to the long charging and water refilling time. Summary of the Invention

[0004] This invention provides an automatic charging and water-filling workstation that reduces workload while improving work efficiency. The specific technical solution is as follows.

[0005] In a first aspect, the present invention provides an automatic charging and water filling workstation, comprising: a housing, a water filling component, a charging component, an electrical component, and a controller installed on the housing, and a first limit switch installed on the water filling component, a second limit switch installed on the charging component, wherein the solenoid valve of the water filling component, the charger of the electrical component, the first limit switch, and the second limit switch are all communicatively connected to the controller; The water inlet pipe of the water inlet assembly and the charging head of the charging assembly both extend to the outside of the housing, and the charger is connected to the charging head via a wire; When the first limit switch is triggered, it sends a water filling signal to the controller. The controller controls the solenoid valve to open according to the water filling signal, and water flows out of the water inlet of the water filling pipe. When the first limit switch switches from the triggered state to the non-triggered state, it sends a disconnect signal to the controller. The controller controls the solenoid valve to close according to the disconnect signal, and water flows out of the water inlet of the water filling pipe. When the second limit switch is triggered, it sends a charging signal to the controller, and the controller controls the charger to start according to the charging signal. When the second limit switch switches from the triggered state to the non-triggered state, it sends a power outage signal to the controller, and the controller controls the charger to shut down according to the power outage signal.

[0006] Optionally, the water inlet pipe and the charging head are both located on the same side of the housing.

[0007] Optionally, the housing includes an upper shell and a base that are interconnected; The water inlet pipe is located above the charging head and both extend to the outside of the upper shell. The water inlet pipe and the charging head have a preset distance in the horizontal direction. The electrical components are installed inside the base.

[0008] Optionally, the base is provided with an openable door.

[0009] Optionally, the base is provided with ventilation holes.

[0010] Optionally, a sliding device and a movable support device are provided below the base.

[0011] Optionally, the water filling assembly further includes an inclined support frame, a water filling pipe mounting base, a water inlet cover, a water pipe cover, two pulleys, two slide rails and a pulley bracket, and a water inlet connector, a solenoid valve water inlet pipe, the solenoid valve, a solenoid valve water outlet pipe, an adapter connector, a telescopic water pipe and the water filling pipe connected in sequence. The first limit switch is fixedly installed on the water filling pipe mounting base, and the position of the end of the water filling pipe mounting base near the water inlet is lower than the other end. The inclined support frame is fixedly installed inside the housing, the water inlet pipe mounting base is fixedly installed above the inclined support frame, the telescopic water pipe extends along the length of the inclined support frame and connects to the water inlet pipe provided at the water inlet pipe mounting base, the water inlet pipe is located inside the water pipe cover, the water pipe cover is fixedly connected to the water inlet cover, the water inlet pipe mounting base is provided with two slide rails, two pulleys are fixedly installed below the pulley bracket, the water inlet cover is fixedly connected to the pulley bracket, and the two pulleys are slidably connected to the corresponding two slide rails respectively; When the water inlet cover is pushed, the water pipe cover moves through the pulley bracket and squeezes the first limit switch, triggering the first limit switch. When the first limit switch is released from the squeeze and resets, it switches from the triggered state to the non-triggered state.

[0012] Optionally, the charging assembly further includes a sliding seat, a charging head mounting seat, a guide rail, a charging baffle, a charging cover, two linear bearings, two springs, and two guide optical shafts, with the second limit switch fixedly mounted on the charging head mounting seat; One end of the charging head passes through the charging cover and extends out from the opening of the charging baffle fixedly installed at the end of the charging cover. The other end of the charging head is fixedly connected to the sliding seat. The sliding seat is slidably connected to the guide rail. The guide rail is fixedly installed in the charging head mounting base and is arranged along the length direction of the charging head mounting base. The charging head mounting base is fixedly installed in the housing. Both guide optical axes are parallel to the guide rail, and one end of each guide optical axis is fixedly connected to the charging head mounting base, while the other end passes through the charging cover and is connected to the corresponding linear bearing. Each spring is sleeved on the outer periphery of the corresponding guide optical axis. When the charging head is pushed, it causes the sliding seat to slide along the guide rail and press the second limit switch, triggering the second limit switch. When the sliding seat is reset by the spring, it switches from the triggered state to the non-triggered state.

[0013] Optionally, the charging cover has a folded edge, and the other end of each guide optical axis passes through the folded edge and is connected to the corresponding linear bearing.

[0014] Optionally, the water inlet pipe is a stainless steel water inlet pipe.

[0015] As described above, the automatic charging and water-filling workstation provided in this embodiment of the invention includes: a housing, a water-filling component, a charging component, an electrical component, and a controller, as well as a first limit switch installed on the water-filling component and a second limit switch installed on the charging component. The solenoid valve of the water-filling component, the charger of the electrical component, the first limit switch, and the second limit switch are all communicatively connected to the controller. The water-filling pipe of the water-filling component and the charging head of the charging component both extend to the outside of the housing, and the charger is connected to the charging head via a wire. When the first limit switch is triggered, it sends a water-filling signal to the controller. The controller controls the solenoid valve to open according to the water-filling signal, and water flows out of the water inlet of the water-filling pipe. When the first limit switch switches from a triggered state to a non-triggered state, it sends a disconnect signal to the controller. The controller controls the solenoid valve to close according to the disconnect signal, and the water inlet of the water-filling pipe stops flowing. When the second limit switch is triggered, it sends a charging signal to the controller. The controller controls the charger to start according to the charging signal. When the second limit switch switches from a triggered state to a non-triggered state, it sends a power-off signal to the controller. The controller controls the charger to shut down according to the power-off signal. Therefore, by setting a first limit switch and a second limit switch on the water filling component and the charging component respectively, when the unmanned sweeper connects to the water inlet and the charging head respectively, the mechanical displacement automatically triggers the corresponding limit switch and sends a water filling signal or a charging signal to the controller. The controller then immediately controls the solenoid valve to open or the charger to start, realizing automatic water filling and automatic charging of the unmanned sweeper without manual operation, greatly reducing workload. When the unmanned sweeper leaves, the limit switch switches from the triggered state to the non-triggered state and sends a disconnection signal or a power outage signal to the controller. The controller automatically controls the solenoid valve to close or the charger to stop, realizing automatic water and power outage. The whole process is fully automated, which can reduce workload and allow the unmanned sweeper to quickly replenish power and water, significantly improving work efficiency.

[0016] The innovative aspects of this invention include: 1. By setting a first limit switch and a second limit switch on the water filling component and the charging component respectively, when the unmanned sweeper connects to the water inlet and the charging head respectively, the mechanical displacement automatically triggers the corresponding limit switch and sends a water filling signal or a charging signal to the controller. The controller then immediately controls the solenoid valve to open or the charger to start, realizing automatic water filling and automatic charging of the unmanned sweeper without manual operation, greatly reducing workload. When the unmanned sweeper leaves, the limit switch switches from the triggered state to the non-triggered state and sends a disconnection signal or a power outage signal to the controller. The controller automatically controls the solenoid valve to close or the charger to stop, realizing automatic water and power outage. The whole process is fully automated, which can reduce workload and allow the unmanned sweeper to quickly replenish power and water, significantly improving work efficiency.

[0017] 2. Since the water inlet pipe and the charging head are located on the same side of the casing and extend towards the unmanned sweeper, the unmanned sweeper only needs to approach the workstation from a single direction to simultaneously connect with the charging head and the water inlet. This eliminates the need for multiple position adjustments, simplifies the connection process, and improves connection efficiency and reliability.

[0018] 3. Because stainless steel has excellent corrosion resistance and mechanical strength, it can resist the erosion of impurities and chemicals in water. Therefore, it can ensure that the water supply pipe is not easy to rust, corrode or be damaged during long-term use, thus extending the service life of the water supply pipe and reducing maintenance costs.

[0019] 4. The design features a split structure of upper shell and base. The upper shell covers the base to form an overall outer shell for protection. Electrical components are installed inside the base and protected by it. The upper shell also provides a mounting base for the water filling component and the charging component. By placing the water filling pipe above the charging head and maintaining a horizontal distance, even if a small amount of water overflows during the water filling process, the horizontal offset can avoid the area of ​​the charging head, thereby significantly reducing the risk of water droplets falling on the charging components and ensuring electrical safety during the charging process.

[0020] 5. By setting an openable door on the base, the electrical components installed in the base can be inspected or maintained directly by opening the door, which is convenient and quick. The inspection work can be completed without disassembling the workstation's upper shell, thus improving maintenance efficiency.

[0021] 6. The ventilation holes allow air to circulate between the inside and outside of the base, effectively dissipating the heat generated by the electrical components during operation, preventing the internal temperature of the base from becoming too high and affecting the performance and lifespan of the electrical components, and ensuring the stability of the workstation during long-term operation.

[0022] 7. By setting up a sliding device, the workstation can slide and move along the ground. The movable support device extends out to support the ground when it needs to be fixed, so that the workstation can be flexibly changed according to actual use needs. At the same time, the stability of the workstation is guaranteed when it needs to be fixed, which expands the scope of application and flexibility of the workstation.

[0023] 8. By setting the telescopic water pipe to extend obliquely along the length of the inclined support frame, when the water inlet cover is pushed, the telescopic water pipe moves obliquely and is compressed axially, effectively absorbing the docking stroke and compensating for positional deviations, resulting in smoother and more reliable docking. Simultaneously, the water pipe mounting base has two slide rails, with two pulleys fixedly installed below the pulley bracket, each slidingly connected to its corresponding slide rail. This ensures smooth sliding guidance for the water inlet cover and water pipe cover. The water pipe cover then presses against the first limit switch, triggering it and sending a water-filling signal to the controller, thus achieving automatic water filling. The obliquely arranged water pipe mounting base allows the water inlet cover to return to its original position along the slide rails under gravity. The pulley bracket and water pipe cover move backward synchronously, the first limit switch releases pressure and returns to its original position, switching from triggered to non-triggered state and sending a disengagement signal to the controller, thus automatically stopping water filling. The structure is simple, the movement is smooth, and the reliability is high.

[0024] 9. By setting a guide optical axis parallel to the guide rail, and a spring sleeved on the outer circumference of the guide optical axis, when the charging head is pushed, the sliding seat drives the charging cover to move along the guide optical axis and compress the spring. The elastic force generated by the spring continuously pushes the charging head to maintain contact pressure with the charging port of the unmanned sweeper, ensuring reliable contact and good stability. At the same time, the sliding seat slides along the guide rail and presses the second limit switch to automatically charge. When the sliding seat returns to the initial position under the elastic force of the two springs, the second limit switch resets from the triggered state to the non-triggered state to stop charging. The structure is compact, responsive, and highly reliable, realizing automatic start and stop of the charging process without manual intervention.

[0025] 10. By setting a folded edge on the charging cover, and connecting the guide optical axis through the folded edge to the linear bearing, the folded edge acts as a connecting transition part. This not only enhances the connection strength between the guide optical axis and the charging cover, making the structure more stable and reliable, but also facilitates the assembly and positioning of the guide optical axis, linear bearing and charging cover, simplifies the assembly process and improves assembly efficiency.

[0026] Of course, implementing any product or method of the present invention does not necessarily require achieving all of the advantages described above at the same time. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] It should be noted that the terms "comprising" and "having," and any variations thereof, in the embodiments and drawings of this invention are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0032] This invention discloses an automatic charging and water-filling workstation, which can reduce workload and improve work efficiency. The embodiments of this invention are described in detail below.

[0033] Figure 1 This is a schematic diagram of an automatic charging and water filling workstation provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of the water supply component provided in an embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of the charging component provided in an embodiment of the present invention.

[0034] See Figure 1-3 The automatic charging and water filling workstation provided in this embodiment of the invention includes: a housing 1, a water filling component 2, a charging component 3, an electrical component 4 and a controller installed on the housing 1, a first limit switch installed on the water filling component 2, a second limit switch installed on the charging component 3, and the solenoid valve 21 of the water filling component 2, the charger of the electrical component 4, the first limit switch and the second limit switch are all communicatively connected to the controller.

[0035] The water inlet pipe 22 of the water inlet assembly 2 and the charging head 31 of the charging assembly 3 both extend to the outside of the housing 1, and the charger is connected to the charging head 31 via a wire. For ease of description, the unmanned robot requiring water inlet and charging is described using an unmanned sweeper as an example in this embodiment of the invention. Of course, other types of unmanned robots can also be used, and this embodiment of the invention does not impose any limitations on them.

[0036] Specifically, the water inlet pipe 22 and the charging head 31 are both located on the same side of the housing 1. Since the water inlet pipe 22 and the charging head 31 are located on the same side of the housing 1 and extend towards the unmanned sweeper, the unmanned sweeper only needs to approach the workstation from a single direction to simultaneously connect with the charging head 31 and the water inlet, without the need for multiple position adjustments, thus simplifying the connection process and improving connection efficiency and reliability.

[0037] In one implementation, the water inlet pipe 22 is a stainless steel water inlet pipe. Because stainless steel has excellent corrosion resistance and mechanical strength, it can resist the erosion of impurities and chemicals in the water. Therefore, it can be ensured that the water inlet pipe 22 is not prone to rusting, corrosion, or damage during long-term use, extending its service life and reducing maintenance costs.

[0038] See also Figure 1 The housing 1 includes an upper shell 11 and a base 12 connected to each other. A water inlet pipe 22 is located above the charging head 31, and both extend to the outside of the upper shell 11. The water inlet pipe 22 and the charging head 31 have a predetermined horizontal distance. The electrical components 4 are installed inside the base 12. The upper shell 11 is the top outer shell of the workstation, used to install the water inlet component 2 and the charging component 3, and also serves to waterproof, dustproof, and protect the internal components. The base 12 is the bottom support structure of the workstation, used to install the electrical components 4.

[0039] Therefore, with the split structure design of the upper shell 11 and the base 12, the upper shell 11 covers the base 12 to form an overall outer shell 1 for protection. The electrical components 4 are installed inside the base 12 and are protected by the base 12. The upper shell 11 also provides a mounting base for the water filling component 2 and the charging component 3. By setting the water filling pipe 22 above the charging head 31 and maintaining a horizontal distance, even if a small amount of water overflows during the water filling process, it can avoid the area of ​​the charging head 31 by horizontal offset, thereby significantly reducing the risk of water droplets falling on the charging components and ensuring electrical safety during the charging process.

[0040] See also Figure 1 The base 12 is equipped with an openable door 121. By providing an openable door 121 on the base 12, when it is necessary to inspect or maintain the electrical components 4 installed in the base 12, the door 121 can be opened directly for operation, which is convenient and quick. The inspection work can be completed without disassembling the workstation upper shell, thus improving maintenance efficiency.

[0041] The base 12 is provided with ventilation holes 122. The ventilation holes 122 allow air to circulate between the inside and outside of the base 12, effectively dissipating the heat generated by the electrical components 4 during operation, preventing the internal temperature of the base 12 from being too high and affecting the performance and service life of the electrical components 4, and ensuring the stability of the workstation during long-term operation.

[0042] A sliding device 123 and a movable support device 124 are provided below the base 12. The sliding device 123 may include casters or wheels, allowing the workstation to be moved from one position to another. The movable support device 124 may include adjustable support legs or leveling feet, which can be adjusted to compensate for uneven ground surfaces, ensuring that the workstation remains stable and level during operation. The sliding device 123 and the movable support device 124 facilitate flexible positioning and installation of the workstation according to actual site requirements.

[0043] Therefore, by setting up the sliding device 123, the workstation can slide and move along the ground, and the movable support device 124 extends out to support the ground when it needs to be fixed, so that the workstation can flexibly change its position according to actual use needs, while ensuring the stability of the workstation when it needs to be fixed, thus expanding the scope of application and flexibility of the workstation.

[0044] When automatic water replenishment is required, the unmanned sweeper approaches the workstation and connects to the water inlet. The first limit switch on the water replenishment component 2 is triggered, sending a water replenishment signal to the controller. After receiving the water replenishment signal, the controller controls the solenoid valve to open, and water begins to flow from the water inlet of the water replenishment pipe 22, thus achieving automatic water replenishment.

[0045] When the unmanned sweeper finishes adding water and drives away, the first limit switch switches from the triggered state to the non-triggered state. The first limit switch sends a disconnect signal to the controller. After receiving the disconnect signal, the controller sends a closing command to the solenoid valve. The solenoid valve responds to the command and closes, and the water inlet of the water pipe 22 stops discharging water, thus achieving automatic water shut-off.

[0046] When automatic charging is required, the unmanned sweeper approaches the workstation and connects to the charging head 31. The second limit switch on the charging assembly 3 is triggered, and the second limit switch sends a charging signal to the controller. After receiving the charging signal, the controller sends a start command to the charger. The charger responds to the command and starts charging the unmanned sweeper.

[0047] When the unmanned sweeper completes charging and drives away, the second limit switch switches from the triggered state to the non-triggered state. The second limit switch sends a power outage signal to the controller. After receiving the power outage signal, the controller sends a shutdown command to the charger. The charger responds to the command and shuts down, stopping charging.

[0048] As described above, the automatic charging and water filling workstation provided in this embodiment of the invention includes: a housing 1, a water filling assembly 2, a charging assembly 3, an electrical assembly 4, and a controller, as well as a first limit switch installed on the water filling assembly 2 and a second limit switch installed on the charging assembly 3. The solenoid valve 21 of the water filling assembly 2, the charger of the electrical assembly 4, the first limit switch, and the second limit switch are all communicatively connected to the controller. The water filling pipe 22 of the water filling assembly 2 and the charging head 31 of the charging assembly 3 both extend to the outside of the housing 1, and the charger is connected to the charging head 31 via a wire. When the first limit switch is triggered, it sends a water filling signal to the controller. The controller then controls the solenoid valve to open, and water flows out of the water inlet of the water inlet pipe 22. When the first limit switch switches from the triggered state to the non-triggered state, it sends a disconnect signal to the controller. The controller then controls the solenoid valve to close, and water flows out of the water inlet of the water inlet pipe 22. When the second limit switch is triggered, it sends a charging signal to the controller. The controller then controls the charger to start. When the second limit switch switches from the triggered state to the non-triggered state, it sends a power outage signal to the controller. The controller then controls the charger to shut down. Therefore, by setting a first limit switch and a second limit switch on the water filling component 2 and the charging component 3 respectively, when the unmanned sweeper connects to the water inlet and the charging head 31 respectively, the mechanical displacement automatically triggers the corresponding limit switch and sends a water filling signal or a charging signal to the controller. The controller then immediately controls the solenoid valve 21 to open or the charger to start, realizing automatic water filling and automatic charging of the unmanned sweeper without manual operation, greatly reducing workload. When the unmanned sweeper leaves, the limit switch switches from the triggered state to the non-triggered state and sends a disconnection signal or a power outage signal to the controller. The controller automatically controls the solenoid valve 21 to close or the charger to stop, realizing automatic water and power outage. The whole process is fully automated, which can reduce workload. The unmanned sweeper can quickly replenish power and water, significantly improving work efficiency.

[0049] See also Figure 2 The water filling assembly 2 also includes an inclined support frame 23, a water filling pipe mounting base 24, a water inlet cover 25, a water pipe cover 26, two pulleys, two slide rails and a pulley bracket 27, and a water inlet connector 280, a solenoid valve inlet pipe 281, a solenoid valve 21, a solenoid valve outlet pipe 282, an adapter connector 283, a telescopic water pipe 284 and a water filling pipe 22 connected in sequence. The first limit switch is fixedly installed on the water filling pipe mounting base 24, and the position of the end of the water filling pipe mounting base 24 near the water inlet is lower than the other end. The inclined support frame 23 is fixedly installed inside the housing 1. The water inlet pipe mounting base 24 is fixedly installed above the inclined support frame 23. The telescopic water pipe 284 extends along the length of the inclined support frame 23 and connects to the water inlet pipe 22 located on the water inlet pipe mounting base 24. The water inlet pipe 22 is located inside the water pipe cover 26. The water pipe cover 26 is fixedly connected to the water inlet cover 25. The water inlet pipe mounting base 24 is provided with two slide rails. Two pulleys are fixedly installed below the pulley bracket 27. The water inlet cover 25 is fixedly connected to the pulley bracket 27. The two pulleys are slidably connected to the corresponding two slide rails. When the water inlet cover 25 is pushed, the water pipe cover 26 is moved by the pulley bracket 27 and squeezes the first limit switch, which is triggered. When the first limit switch is released from the squeeze and resets, it switches from the triggered state to the non-triggered state.

[0050] The inlet connector 280 is used to connect to an external water source pipeline, introducing external water into the solenoid valve 21; the solenoid valve inlet pipe 281 and the solenoid valve outlet pipe 282 are pipelines connecting to the solenoid valve 21, used to guide water flow; the solenoid valve 21 is an electromagnetically controlled valve, used to control the on / off state of the water circuit; the adapter connector 283 is used to connect the solenoid valve outlet pipe 282 and the telescopic water pipe 284, realizing pipeline transition; the telescopic water pipe 284 is a flexible pipeline that can extend and retract axially, used to absorb docking stroke and compensate for positional deviation; the water filling pipe 22 is a stainless steel water pipe, and the front end of the water filling pipe 22 is a water filling port, used to dock with the water inlet of the unmanned sweeper. The first limit switch is fixedly installed on the water filling pipe mounting base 24 at the point where it can be squeezed by the water pipe cover 26.

[0051] See also Figure 2 The inclined support frame 23 is a fixed bracket, which is fixedly installed inside the housing 1 to support and fix the water pipe mounting seat 24. The water pipe mounting seat 24 is used to install and fix the water pipe 22, and is provided with two parallel slide rails to guide the sliding of the water inlet cover 25. The pulley bracket 27 is a connecting bracket, with two pulleys fixedly installed below. The two pulleys are respectively embedded in the two corresponding slide rails and can slide along the slide rails to realize the sliding connection between the pulley bracket 27 and the water pipe mounting seat 24.

[0052] Specifically, the water inlet pipe mounting base 24 is positioned at a lower end than the water inlet, and is arranged at an angle. The inclined support frame 23 is also arranged at an angle, and the water inlet pipe mounting base 24 is fixedly installed above the inclined support frame 23. The telescopic water pipe 284 extends obliquely along the length of the inclined support frame 23 and connects to the water inlet pipe 22 located on the water inlet pipe mounting base 24, so that the telescopic water pipe 284 moves obliquely as it is pushed by the water inlet cover 25, thereby achieving axial compression.

[0053] See also Figure 2The water pipe cover 26 is fitted over the water pipe 22 to protect the water pipe 22; the water inlet cover 25 is fitted over the water pipe cover 26 to prevent water and dust; the water inlet cover 25 is fixedly connected to the pulley bracket 27, preferably by a threaded connection or a snap-fit ​​connection, so that the pulley bracket 27 can move synchronously when the water inlet cover 25 is pushed.

[0054] When the unmanned sweeper enters the water filling station, its water inlet touches and pushes the water inlet cover 25. Since the water inlet cover 25 is fixedly connected to the pulley bracket 27, the two pulleys slide along their corresponding two slide rails. The water inlet cover 25 drives the pulley bracket 27 forward along the slide rail of the water pipe mounting seat 24. The pulley bracket 27 then drives the water pipe cover 26 forward, which presses the first limit switch. The first limit switch is triggered and sends a water filling signal to the controller.

[0055] Since the water inlet pipe mounting base 24 is arranged at an angle, the telescopic water pipe 284 extends at an angle along the length of the inclined support frame 23. When the water inlet cover 25 is pushed, the telescopic water pipe 284 moves at an angle and is squeezed and axially compressed, absorbing the docking stroke and compensating for the position deviation.

[0056] When the unmanned sweeper finishes refilling water and drives away, the water inlet is released from the pushing force on the water inlet cover 25. Because the water pipe mounting base 24 is inclined, the water inlet cover 25 returns to its original position along the slide rail under gravity. The pulley bracket 27 and the water pipe cover 26 move backward synchronously, the first limit switch loses its pressure and resets, switching from a triggered state to a non-triggered state and sending a disengagement signal to the controller.

[0057] Therefore, by setting the telescopic water pipe 284 to extend obliquely along the length of the inclined support frame 23, when the water inlet cover 25 is pushed, the telescopic water pipe 284 moves obliquely and is compressed axially, which can effectively absorb the docking stroke and compensate for positional deviation, making the docking smoother and more reliable. At the same time, the water pipe mounting base 24 is provided with two slide rails, and two pulleys are fixedly installed below the pulley bracket 27 and are slidably connected to the corresponding slide rails, realizing the smooth sliding guidance of the water inlet cover 25 and the water pipe cover 26. Then, the water pipe cover 26 presses the first limit switch, the first limit switch is triggered and sends a water filling signal to the controller, thereby realizing automatic water filling. By setting the water pipe mounting base 24 in an oblique arrangement, the water inlet cover 25 returns to its original position along the slide rail under the action of gravity. The pulley bracket 27 and the water pipe cover 26 move backward synchronously. The first limit switch loses the compression and returns to its original position, switching from the triggered state to the non-triggered state, and sends a disengagement signal to the controller, thereby realizing automatic water filling stop. The structure is simple, the movement is smooth and the reliability is high.

[0058] See also Figure 3The charging assembly 3 also includes a sliding seat 32, a charging head mounting seat 33, a guide rail 34, a charging baffle 35, a charging cover 36, two linear bearings 37, two springs and two guide optical shafts 38, and a second limit switch is fixedly installed on the charging head mounting seat 33. One end of the charging head 31 passes through the charging cover 36 and extends out from the opening of the charging baffle 35 fixedly installed at the end of the charging cover 36. The other end of the charging head 31 is fixedly connected to the sliding seat 32. The sliding seat 32 is slidably connected to the guide rail 34. The guide rail 34 is fixedly installed in the charging head mounting base 33 and is arranged along the length direction of the charging head mounting base 33. The charging head mounting base 33 is fixedly installed in the housing 1. Both guide optical axes 38 are parallel to the guide rail 34, and one end of each guide optical axis 38 is fixedly connected to the charging head mounting base 33, and the other end passes through the charging cover 36 and is connected to the corresponding linear bearing 37. Each spring is sleeved on the outer periphery of the corresponding guide optical axis 38. When the charging head 31 is pushed, it causes the sliding seat 32 to slide along the guide rail 34 and press the second limit switch. The second limit switch is triggered. When the sliding seat 32 is reset by the spring, it switches from the triggered state to the non-triggered state.

[0059] The charging head 31 is used to connect with the charging port of the unmanned sweeper to achieve electrical connection; the charging head mounting base 33 is a mounting base used to fix it in the housing 1 and to support and fix other charging components; the guide rail 34 is fixedly installed in the charging head mounting base 33 and is set along the length of the charging head mounting base 33 to provide sliding guidance for the sliding seat 32; the sliding seat 32 is slidably connected to the guide rail 34 to install the charging head 31 and move axially along the guide rail 34.

[0060] See also Figure 3 The charging cover 36 is a cylindrical protective cover used to protect the internal charging structure and to provide waterproof and dustproof protection. The charging baffle 35 is fixedly installed at the end of the charging cover 36 and has an opening. One end of the charging head 31 passes through the charging cover 36 and extends out from the opening of the charging baffle 35. The other end of the charging head 31 is fixedly connected to the sliding seat 32.

[0061] Both guide optical shafts 38 are arranged parallel to the guide rail 34. One end of each guide optical shaft 38 is fixedly connected to the charging head mounting base 33, and the other end passes through the charging cover 36 and is connected to the corresponding linear bearing 37. The linear bearing 37 is mounted on the charging cover 36 and slides in cooperation with the guide optical shaft 38 to support and guide the axial movement of the charging cover 36. Each spring is sleeved on the outer periphery of the corresponding guide optical shaft 38 to generate elastic force when the charging cover 36 is pushed, maintaining the contact pressure between the charging head 31 and the charging port of the unmanned sweeper.

[0062] The second limit switch is fixedly installed on the charging head mounting base 33 and is used to detect the movement position of the sliding base 32.

[0063] When the unmanned sweeper enters the charging station, its charging port abuts against and pushes the charging head 31. Since the charging head 31 is fixedly connected to the sliding seat 32, the pushing of the charging head 31 causes the sliding seat 32 to slide forward along the guide rail 34. When the sliding seat 32 slides to a preset position, it presses the second limit switch, which is then triggered and sends a charging signal to the controller.

[0064] During this process, the charging cover 36 and the charging baffle 35 move forward synchronously with the sliding seat 32, the two springs are compressed respectively, and the two guide optical shafts 38 slide axially relative to the corresponding linear bearings 37. The elastic force generated after the springs are compressed continues to act on the charging cover 36, pushing the charging head 31 to maintain reliable contact with the charging port of the unmanned sweeper, ensuring the stability of the charging electrical connection.

[0065] When the unmanned sweeper completes charging and drives away, the charging port disengages from the pushing force on the charging head 31. The sliding seat 32 returns to its initial position under the elastic force of the two springs, and the second limit switch resets from the triggered state to the non-triggered state, sending a power-off signal to the controller.

[0066] Therefore, by setting a guide optical axis 38 parallel to the guide rail 34, and with a spring sleeved on the outer periphery of the guide optical axis 38, when the charging head 31 is pushed, the sliding seat 32 drives the charging cover 36 to move along the guide optical axis 38 and compress the spring. The elastic force generated by the spring continuously pushes the charging head 31 to maintain contact pressure with the charging port of the unmanned sweeper, ensuring reliable contact and good stability. At the same time, the sliding seat 32 slides along the guide rail 34 and presses the second limit switch to automatically charge. When the sliding seat 32 returns to its initial position under the elastic force of the two springs, the second limit switch resets from the triggered state to the non-triggered state to stop charging. The structure is compact, responsive, and highly reliable, realizing automatic start and stop of the charging process without manual intervention.

[0067] See also Figure 3 The charging cover 36 has a folded edge 361, and the other end of each guide optical axis 38 passes through the folded edge 361 and is connected to the corresponding linear bearing 37.

[0068] The folded edge 361 is a bent and folded edge structure at the end of the charging cover 36, used for connection and fixation with other components.

[0069] The other end of each guide optical axis 38 passes through the folded edge 361 and is connected to the corresponding linear bearing 37. Specifically, one end of the guide optical axis 38 is fixedly connected to the charging head mounting base 33, and the shaft extends in a direction parallel to the guide rail 34, passes through the folded edge 361 and is connected to the linear bearing 37 located on the outside of the charging cover 36.

[0070] The folded edge 361 serves as a connecting transition between the guide optical axis 38 and the linear bearing 37, enhancing the connection strength and structural stability between the guide optical axis 38 and the charging cover 36.

[0071] Therefore, by providing a folded edge 361 on the charging cover 36, and connecting the guide optical shaft 38 through the folded edge 361 to the linear bearing 37, the folded edge 361 serves as a connecting transition piece. This not only enhances the connection strength between the guide optical shaft 38 and the charging cover 36, making the structure more stable and reliable, but also facilitates the assembly and positioning of the guide optical shaft 38, the linear bearing 37, and the charging cover 36, simplifying the assembly process and improving assembly efficiency.
