Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and in particular to a distributed contact charging pile. Background Technology

[0002] Wheeled robots are typically products that use LiDAR and depth cameras to achieve autonomous positioning and navigation. In order to achieve unmanned operation throughout the entire process, wheeled robots are usually equipped with automatic charging functions. The most common method is to use radar to identify the characteristics of charging piles and then automatically charge the piles.

[0003] Currently, there are two main charging methods in the industry: 1. Electrode contact charging: This involves energizing the wheeled robot by aligning its electrode plates with the charging station's electrode plates, typically with a charging current of 3A-10A. This method generally utilizes the planes of the two electrode plates for contact. However, due to installation errors between the wheeled robot and the charging station, uneven ground surfaces, and lateral angular deviations in the robot's autonomous charging, the electrode contact surfaces are prone to partial suspension, resulting in incomplete contact. This poor contact can lead to a charging efficiency decrease of over 30%, and in severe cases, arc discharge, accelerating electrode material oxidation and creating a vicious cycle. 2. Slot charging: This method achieves reliable electrode contact through an elastic clamping mechanism. Specifically, it employs two pre-tensioned spring-loaded blocks. However, during long-term operation testing, it was found that when the clamping force is too large, the separation force required for the robot to detach from the charging pile will increase significantly. When the robot leaves the charging pile after charging, it is easy to drag the charging pile along with it. This movement accumulates and causes the position of the charging pile to deviate from the calibrated zero position more and more, eventually leading to the failure of the robot to charge the pile in the future. Conversely, due to the long-term use of the elastic clamping mechanism, when the clamping force is too small, it is easy to make a false contact. Utility Model Content

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Distributed contact charging stations include:

[0007] A protective shell has an internal cavity, and an identification groove is provided on the outer wall of the protective shell. A mounting boss is provided at the bottom of the identification groove, and the mounting boss has a positive electrode mounting area and a negative electrode mounting area.

[0008] A charging adapter has a positive output terminal and a negative output terminal, and the charging adapter is fixedly installed inside the protective shell;

[0009] Multiple flexible charging components are disposed in the positive mounting area of ​​the mounting boss and electrically connected to the positive output terminal of the charging adapter, and multiple flexible charging components are disposed in the negative mounting area of ​​the mounting boss and electrically connected to the negative output terminal of the charging adapter.

[0010] As an optional solution for distributed contact charging piles, the mounting boss is provided with mounting holes, and the flexible charging component includes:

[0011] An insulating tube housing is fixedly installed in the mounting hole, and a first through hole and a second through hole are respectively provided at both ends of the insulating tube housing;

[0012] A telescopic component is inserted into the insulating tube shell. The two ends of the telescopic component are a contact part and a connecting part, respectively. The contact part is inserted through the first through hole, and the connecting part is inserted through the second through hole. The connecting part is electrically connected to the charging adapter.

[0013] An elastic reset member is disposed inside the insulating housing, and the elastic reset member has a tendency to keep the contact portion extending out of the insulating housing.

[0014] As an optional solution for distributed contact charging piles, the telescopic component is provided with an annular limiting part, the elastic reset component is sleeved on the telescopic component, and the two ends of the elastic reset component abut against the annular limiting part and the bottom wall of the insulating tube shell respectively. The outer diameter of the annular limiting part is larger than the inner diameter of the first through hole, and the annular limiting part stops at the top wall of the insulating tube shell.

[0015] As an optional solution for distributed contact charging piles, the size of the groove opening of the identification groove gradually decreases along the groove depth direction.

[0016] As an optional solution for distributed contact charging piles, the protective shell includes a front shell and a rear shell, which are interlocked and enclosed to form the receiving chamber. The identification groove and the mounting boss are both located on the outer wall surface of the front shell.

[0017] As an optional solution for distributed contact charging piles, the distributed contact charging piles also include:

[0018] The mounting frame has mounting feet around its perimeter. Fasteners pass through the mounting feet and connect to the inner wall of the front housing. The charging adapter is sandwiched between the mounting frame and the inner wall of the front housing.

[0019] As an optional solution for distributed contact charging piles, the rear shell is evenly provided with multiple heat dissipation holes, the mounting frame is provided with a folding plate section, and the distributed contact charging pile further includes:

[0026] The distributed contact charging pile provided by this utility model houses the charging adapter within a protective shell. The protective shell has identification grooves. A wheeled robot can use radar to acquire the shape and size characteristics of the identification grooves, facilitating its navigation to the charging pile. Alternatively, the robot can utilize its own guiding structure to insert into the identification grooves, further improving the accuracy of charging. The bottom of the identification groove has mounting bosses. Multiple elastic charging components are located in the positive mounting area of ​​the mounting bosses and electrically connected to the positive output terminal of the charging adapter. Multiple elastic charging components are also located in the negative mounting area of ​​the mounting bosses and electrically connected to the negative output terminal of the charging adapter. By adding multiple elastic charging components, a point-to-surface contact method replaces the surface-to-surface contact method, achieving a multi-contact distribution on a single electrode. This maximizes the reduction of the risk of false contact and expands the error tolerance caused by charging pile accuracy. Furthermore, the wheeled robot will not exert any drag force on the charging pile when it leaves the charging pile. Attached Figure Description

[0046] Wheeled robots, as an important representative of modern intelligent equipment, are typical products that utilize advanced sensor technologies such as LiDAR and depth cameras to achieve autonomous positioning and navigation. These robots can autonomously plan paths, avoid obstacles, and complete various preset tasks by perceiving their surrounding environment in real time. To achieve fully automated operation without human intervention and further improve their application efficiency, wheeled robots are usually equipped with automatic charging functions to ensure long-term continuous operation without manual intervention. Currently, the commonly used automatic charging method in the industry is to use radar systems to identify specific characteristics of charging stations and guide the robot to automatically complete the charging operation.

[0047] Currently, the industry has developed two representative charging methods to meet the automatic charging needs of wheeled robots:

[0048] The first type is electrode contact charging. The core principle of this method is that when the wheeled robot moves near a charging station, its onboard electrode plates make physical contact with the pre-installed electrode plates on the charging station, establishing a power circuit and enabling energy transfer. Typically, the charging current for this method is set between 3A and 10A to meet the robot's battery charging requirements. In practical applications, electrode contact charging generally utilizes the close contact between the planes of two electrode plates. However, due to various objective factors, this contact method faces numerous challenges in actual operation. Specifically, there may be installation errors between the electrode plates on the wheeled robot and those on the charging station, preventing perfect alignment. Additionally, the ground where the charging station is placed may be uneven, further increasing the difficulty of alignment. Furthermore, the wheeled robot may experience lateral angular deviations during autonomous charging and alignment. These factors combined can easily cause localized suspension of the electrode contact surface, resulting in a false contact. This poor contact problem can lead to a series of serious consequences. First, it will cause a significant decrease in charging efficiency. According to relevant test data, the charging efficiency may decrease by more than 30%. More seriously, in extreme cases, poor contact may also trigger arc discharge, which will accelerate the oxidation process of electrode materials and form a vicious cycle, seriously affecting the service life of the electrode sheet and the reliability of charging.

[0049] The second type is slot-type charging. Unlike electrode contact charging, slot-type charging uses an elastic clamping mechanism to achieve reliable electrode contact. Specifically, this charging method employs a pre-tensioned spring-loaded block structure. When the wheeled robot moves to the slot position of the charging station, the two spring-loaded blocks clamp the electrodes under the pre-tension, ensuring good contact between the electrodes. However, in actual long-term operation testing, slot-type charging has also revealed some problems. When the clamping force is set too high, although it can ensure tight contact between the electrodes, the separation force required for the robot to detach from the charging station also increases significantly. This means that when the robot leaves the charging station after charging, it needs to overcome greater resistance to achieve separation. In this case, the robot is prone to dragging the charging station along, especially when the robot frequently performs charging operations. This movement gradually accumulates, causing the deviation of the charging station position from the calibrated zero position to become increasingly larger. Ultimately, when the deviation exceeds a certain range, it will cause subsequent robot charging to fail, seriously affecting the robot's automatic charging function. Conversely, if the clamping force is set too small, although it can reduce the difficulty of the robot leaving the charging station, the clamping force may be further reduced due to problems such as elastic decay of the elastic clamping mechanism during long-term use. This can easily lead to false contact, a problem similar to that faced by electrode contact charging.

[0050] To enable simultaneous conductive contact at multiple points and reduce the risk of incomplete contact between the wheeled robot and the charging station, this embodiment provides a distributed contact charging station. The following describes a related embodiment... Figures 1 to 7 The specific content of this embodiment will be described in detail.

[0051] The distributed contact charging pile in this embodiment includes a protective shell, a charging adapter 2, and several flexible charging components 3. The protective shell, as the external protective structure of the entire charging pile, has an internal cavity designed to provide a safe and stable space for the internal components such as the charging adapter 2, effectively preventing external environmental factors from corroding and damaging the internal components, and extending the service life of the charging pile. The outer wall of the protective shell is provided with an identification groove 11, and the bottom of the identification groove 11 is further provided with a mounting boss 12, which divides the positive and negative mounting areas. The charging adapter 2, as the core power supply component of the charging pile, has a positive output terminal 21 and a negative output terminal 22. The charging adapter 2 is securely fixed within the cavity of the protective shell. In this way, the charging adapter 2 can safely and reliably provide a stable power output to the entire charging system, ensuring the smooth progress of the charging process. The several flexible charging components 3 are one of the key innovations of this charging pile. Multiple flexible charging components 3 are disposed in the positive mounting area of ​​the mounting boss 12 and electrically connected to the positive output terminal 21 of the charging adapter 2; similarly, multiple flexible charging components 3 are disposed in the negative mounting area of ​​the mounting boss 12 and electrically connected to the negative output terminal 22 of the charging adapter 2. This layout allows the charging pile to form a situation where multiple contacts simultaneously contact the electrode plates of the wheeled robot during the charging process.

[0052] The distributed contact charging pile provided by this utility model houses the charging adapter 2 within a protective shell, achieving centralized management and protection of internal components. Furthermore, the identification groove 11 on the protective shell plays a crucial role. During the autonomous search for charging piles, the wheeled robot can accurately acquire the shape and size characteristics of the identification groove 11 using its onboard radar system. This feature information acts like a unique identification card for the charging pile, guiding the wheeled robot quickly and accurately to its location, significantly improving search efficiency. Simultaneously, the wheeled robot can also insert its own guiding structure into the identification groove 11. This physical contact guidance method further enhances the accuracy of charging, ensuring the robot can accurately dock with the charging pile, laying a solid foundation for subsequent charging operations.

[0053] The mounting boss 12 at the bottom of the groove 11, and the multiple flexible charging components 3 rationally arranged in the positive and negative electrode mounting areas of the mounting boss 12, constitute a unique charging contact mode. By adding multiple flexible charging components 3, a multi-point-to-surface contact method is adopted to replace the traditional surface-to-surface contact method, realizing a design with multiple contact points distributed on a single electrode. This design brings several technical benefits. First, it can minimize the risk of false contact. In actual charging, due to various factors, such as installation errors between the robot and the charging pile, uneven ground, etc., the traditional surface-to-surface contact method is prone to local suspension, resulting in false contact. However, the multiple contact point design of this charging pile ensures that even if some contacts have poor contact, other contacts can still maintain good contact, thus ensuring the stable progress of the charging process. Second, it expands the tolerance for errors caused by pile alignment accuracy. During the autonomous alignment process, wheeled robots inevitably have certain angular or positional deviations. Traditional charging methods have low tolerance for these deviations; once the deviation exceeds a certain range, it may lead to charging failure. The multiple contact points of this charging station can adapt to robot alignment deviations to a certain extent. As long as most contacts can make contact with the robot's electrode plates, charging can be achieved, greatly improving the charging success rate. Furthermore, this design prevents the charging station from being dragged when the wheeled robot needs to detach after charging. Because the contacts of the multiple elastic charging components 3 can adaptively adjust according to the robot's detachment movement, excessive resistance is avoided due to robot movement, preventing the charging station from being dragged and displaced. This ensures the stability of the charging station's position and provides a reliable guarantee for charging other robots subsequently.

[0054] Furthermore, the mounting boss 12 is provided with mounting holes, and the elastic charging assembly 3 includes an insulating tube shell 31, a telescopic member 32, and an elastic reset member 33. The insulating tube shell 31 is fixedly installed in the mounting holes, providing insulation and mechanical protection for other internal components. The insulating tube shell 31 has a first through hole 311 and a second through hole 312 at both ends, providing necessary space for the flexible movement of the telescopic member 32. The telescopic member 32 passes through the insulating tube shell 31, with a contact portion 321 and a connecting portion 322 at its two ends. The contact portion 321 passes through the first through hole 311 and directly contacts the electrode plates of the wheeled robot, serving as a key contact point for power transmission. The connecting portion 322 passes through the second through hole 312 and is electrically connected to the charging adapter 2, ensuring smooth power transmission from the charging adapter 2 to the telescopic member 32. This design allows the telescopic member 32 to extend and retract freely within the insulating housing 31 while ensuring the reliability of the electrical connection. The elastic reset member 33 is disposed within the insulating housing 31 and tends to keep the contact portion 321 always extending beyond the insulating housing 31.

[0055] Specifically, this charging pile adopts a distributed arrangement of multiple contacts on a single electrode, with parallel wiring at the tail end to further improve the reliability of charging. In actual charging scenarios, when a single contact experiences a false contact or is not parallel to the charging pile plane, each contact 321 will adaptively adjust its compression under the elastic force of the elastic reset member 33. This adaptive adjustment capability allows the contact 321 to automatically adjust the contact pressure and contact area with the robot electrode plate according to the actual situation, maximizing the contact area between the contact 321 of the telescopic member 32 and the robot electrode plate, thereby ensuring unimpeded charging. For example, if a contact 321 of one telescopic member 32 is slightly suspended due to uneven ground, the contact 321s of other telescopic members 32 will automatically increase their compression to compensate for the insufficient contact area, ensuring that the overall charging effect is not affected. In the design of parallel wiring of the connecting parts 322 of the telescopic members 32, it is necessary to ensure that sufficient wire length is reserved for different telescopic members 32 according to their installation positions. This is to ensure that each telescopic component 32 operates independently during extension and retraction, preventing the swaying of the cable from affecting the normal operation of other telescopic components 32. If the cable length is insufficient, the extension or retraction of one telescopic component 32 may pull on the cables of other telescopic components 32, causing slight changes in the position of other contacts and thus affecting their contact with the robot's electrode plates. With sufficient cable length, each contact can extend and retract freely without interference, thereby ensuring the stability and reliability of the entire charging system.

[0056] Furthermore, the telescopic member 32 is provided with an annular limiting part 323, and an elastic reset member 33 is sleeved on the telescopic member 32. Both ends of the elastic reset member 33 abut against the annular limiting part 323 and the bottom wall of the insulating shell member 31, respectively. The outer diameter of the annular limiting part 323 is larger than the inner diameter of the first through hole 311, and the annular limiting part 323 stops against the top wall of the insulating shell member 31. Due to the interaction between the annular limiting part 323 and the top wall of the insulating shell member 31, the telescopic member 32 is prevented from popping out of the insulating shell member 31 under the action of the elastic reset member 33, ensuring that the telescopic member 32 always moves within a preset safe range. During normal charging contact, the telescopic member 32 provides positive pressure to the contact points through the elastic reset member 33 inside the insulating shell member 31, avoiding false contact and thus ensuring the contact stability between the charging contacts and the robot electrode plates. For example, when the wheeled robot shakes a bit when docking with the charging station, the telescopic component 32 can maintain a relatively stable contact state under the combined action of the annular limiting part 323 and the elastic reset part 33, thus avoiding the problem of charging interruption or reduced charging efficiency caused by unstable contact.

[0057] Furthermore, the size of the groove 11 gradually decreases along its depth. Specifically, the wall of the groove 11 is not perpendicular to the bottom, but rather features a sloping design with a certain angle. Visually, the groove is trapezoidal, wider at the top and narrower at the bottom. The primary function of this sloping design is to effectively guide the wheeled robot to align with the charging station. In actual charging scenarios, the wheeled robot needs to autonomously drive to the charging station and achieve precise docking to enable charging. However, due to the complex environment, the robot's limited positioning accuracy, and various interference factors during travel, the robot often struggles to align accurately on the first attempt when approaching the charging station. This is where the sloping design of the groove 11 plays a crucial role. As the wheeled robot approaches the charging station, its front-end sensor or recognition device first detects the groove 11. Due to the relatively large groove size, the robot's guidance structure has a large margin of error, allowing it to smoothly enter the groove even with initial positional deviations. As the robot continues to move forward, the groove size gradually decreases, and the sloping wall of the groove exerts a lateral guiding force on the robot's guidance structure. This guiding force gently propels the robot to adjust its position and orientation, gradually moving it closer to the center of the groove, greatly improving the docking accuracy between the wheeled robot and the charging station.

[0058] Furthermore, the protective shell includes a front shell 1 and a rear shell 7, which interlock and enclose to form a receiving chamber. The identification groove 11 and the mounting boss 12 are both located on the outer wall surface of the front shell 1. The connection method between the front shell 1 and the rear shell 7 has several options, including adhesive bonding, snap-fitting, or bolting, without further restrictions. Adhesive bonding uses a high-strength, weather-resistant adhesive to tightly bond the front shell 1 and rear shell 7 together, creating a seamless connection. This method is easy to operate and has a clean appearance, while effectively preventing moisture and dust from seeping in at the connection point, further improving the sealing performance of the protective shell. Snap-fitting utilizes a snap-fit ​​structure designed on the front shell 1 and rear shell 7, achieving a quick and secure connection through interlocking. The advantage of snap-fitting is that installation and disassembly are very convenient, requiring no additional tools, greatly improving the efficiency of maintenance and component replacement. In scenarios requiring frequent maintenance and repair, snap-fitting can significantly reduce maintenance time and costs. Bolted connections are known for their high strength and stability. By using bolts and nuts to secure the front shell 1 and rear shell 7 together, they can withstand significant external forces, making them suitable for environments requiring high structural strength. For example, in outdoor environments, charging stations may be affected by wind, vibration, and other external forces. Bolted connections ensure the structural integrity of the protective shell, preventing the front shell 1 and rear shell 7 from separating due to external forces. In terms of protection, the enclosure formed by the front shell 1 and rear shell 7 together constructs a robust protective system, effectively protecting internal components from external environmental damage and improving the reliability and durability of the charging station. Optionally, the rear shell 7 is provided with a cable hole 73, allowing the external wiring of the charging adapter 2 to pass through the rear shell.

[0059] Furthermore, the distributed contact charging pile also includes a mounting frame 4, with mounting legs 41 arranged around the mounting frame 4. Fasteners pass through the mounting legs 41 and connect to the inner wall of the front shell 1. The charging adapter 2 is clamped between the mounting frame 4 and the inner wall of the front shell 1.

[0060] In actual installation, fasteners play a crucial role. Fasteners such as bolts and screws pass through pre-drilled holes in the mounting legs 41 and are then tightly connected to the inner wall of the front shell 1. The strong clamping force of the fasteners firmly fixes the mounting frame 4 inside the front shell 1, effectively preventing loosening or displacement of the mounting frame 4 due to vibration, external impact, or other factors during use, thus ensuring the stability and reliability of the entire charging pile structure. For example, the U-shaped groove structure of the mounting frame 4 provides a relatively independent and stable installation space for the charging adapter 2. The two side walls of the U-shaped groove can laterally limit the movement of the charging adapter 2, preventing it from shaking in the vertical direction. On the other hand, the inner wall of the front shell 1 cooperates with the mounting frame 4 to fix the charging adapter 2 from another direction, further enhancing its installation stability. This double-fixing method allows the charging adapter 2 to maintain a stable working state during charging, reducing the risk of poor contact, short circuits, and other malfunctions caused by shaking, and improving the reliability and safety of charging.

[0061] Regarding material selection, the mounting frame 4 can be made of either plastic or metal, each with its unique properties and applicable scenarios. Plastic offers advantages such as light weight, low cost, and good insulation. For charging station applications with strict weight requirements and limited budgets, such as small indoor charging locations or charging devices requiring portability, a plastic mounting frame 4 effectively reduces the overall weight of the charging station, facilitating installation and relocation while lowering production costs. Furthermore, plastic's excellent insulation properties prevent safety accidents caused by leakage during charging, improving the charging station's safety. Metal, on the other hand, boasts high strength, good corrosion resistance, and excellent heat dissipation. In scenarios with high structural strength requirements and harsh operating environments, such as large outdoor charging stations or industrial production workshops, a metal mounting frame 4 can withstand greater external forces, resist harsh environmental corrosion, and ensure the long-term stable operation of the charging station. Simultaneously, the excellent heat dissipation of metal effectively dissipates heat generated during charging, preventing overheating from affecting the performance and lifespan of the charging adapter 2.

[0062] Furthermore, the rear shell 7 is evenly provided with multiple heat dissipation holes 71. During operation, the electronic components inside the charging pile, especially the charging adapter 2, generate a large amount of heat. If this heat is not dissipated in time, it will cause the component temperature to rise, thereby affecting its performance and lifespan, and may even cause malfunctions. The presence of heat dissipation holes 71 provides a channel for heat dissipation, allowing the internal hot air to exchange with the external cold air to achieve the best heat dissipation effect. The mounting frame 4 is provided with a folding plate part 42, and this unique structural design provides an ideal position for the installation of the cooling fan 5. The distributed contact charging pile is also equipped with a cooling fan 5, which is firmly installed on the folding plate part 42, with the air outlet side of the cooling fan 5 facing the rear shell 7. When the cooling fan 5 is activated, it accelerates the airflow, forming a strong airflow. This airflow blows out from the air outlet side of the cooling fan 5 and directly hits the heat dissipation holes 71 on the rear shell 7, which can more effectively exhaust the hot air inside the charging pile to the external environment through the heat dissipation holes 71. Meanwhile, external cold air can also enter the charging pile through other means (such as the heat dissipation holes 71 that are not directly opposite the cooling fan 5), forming convection, which greatly improves the heat dissipation efficiency. This combination of active and passive heat dissipation ensures that the internal temperature of the charging pile remains within a reasonable range during long-term high-load operation, guaranteeing the stable operation of the charging pile.

[0063] Furthermore, the mounting frame 4 has a perforated structure 43 corresponding to the charging adapter 2. The reasonable shape and size of the perforation ensures that the charging adapter 2 has sufficient contact area with the surrounding air for heat dissipation, while preventing the perforation from being too large and affecting the structural strength of the mounting frame 4. The addition of the perforated structure 43 further optimizes the heat dissipation effect. The charging adapter 2 is one of the main heat sources during operation. The perforated structure 43 on the mounting frame 4 allows for more airflow around the charging adapter 2. Air can pass more freely through the perforated structure 43, making full contact with the surface of the charging adapter 2 and carrying away more heat. Compared with traditional enclosed mounting methods, this perforated design significantly reduces the temperature of the charging adapter 2, improving its working efficiency and lifespan.

[0064] Furthermore, the distributed contact charging pile also includes a dustproof mesh 6, which is installed on the rear shell 7 and covers the heat dissipation holes 71. Without the protection of the dustproof mesh 6, dust would enter the charging pile through the heat dissipation holes 71 and adhere to the surface of electronic components. The accumulation of dust will lead to a decrease in the heat dissipation performance of electronic components and may also cause malfunctions such as short circuits. The dustproof mesh 6 acts as a barrier, effectively preventing dust and debris from entering the charging pile. At the same time, the design of the dustproof mesh 6 fully considers the needs of air circulation. The aperture of the dustproof mesh 6 can ensure that air can pass through smoothly while blocking dust to the greatest extent, achieving a good balance between dust prevention and heat dissipation, and extending the service life of the charging pile.

[0065] Furthermore, a handle groove 72 is recessed on the outer wall of the rear shell 7. This allows users to easily and comfortably grip and lift the charging station, greatly improving ease of use. When it is necessary to move or transport the charging station, users can simply place their fingers into the handle groove 72 to easily grip it. The design of the handle groove 72 makes the user's grip more secure and less prone to slipping, reducing the risk of damage to the charging station due to improper handling.
