[0002] In the current market environment, the design and manufacture of the electrical contact terminals of charging bases face huge cost pressures. Especially in applications such as pool cleaning robots, it is necessary to solve the electrolysis problem during charging. The traditional approach is usually to stamp out bumps on a metal plate and combine composite plating technology as the electrical contact terminals for charging. However, this method is not only costly, but also results in material waste because only the bump parts actually play a contact role. Summary of the Invention

[0015] It is to be understood that both the foregoing general description and the following detailed description are exemplary and are intended to provide further explanation of the claimed technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solutions and advantages of the present disclosure more obvious, the exemplary embodiments according to the present disclosure will be described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure. It should be understood that the present disclosure is not limited by the exemplary embodiments described herein.

[0024] At present, most of the electrical contact terminals of existing charging bases are composed of the technology of stamping bumps on a metal plate plus composite plating. This will cause the problem of high cost, and for the stamping bumps on the metal plate, only the bump part plays a role, which will also cause waste of materials in other places.

[0025] Therefore, the present disclosure provides an electrical contact terminal of a charging base, which can be directly composed of the protruding part bent from an integral strip-shaped member, and the electrical contact terminal is composed of a slow electrolysis material, which has the ability of slow electrolysis while achieving good electrical contact. Compared with the existing technology of stamping bumps on a metal plate and composite plating, the processing technology is simple, the material utilization rate is high, and the production cost is greatly reduced.

[0026] First, as Figure 1 shown, a schematic diagram of the overall charging system of a pool device provided by an embodiment of the present disclosure. As Figure 1 shown, the entire charging system of the pool device 102 includes: a charging base 101.

[0027] In the present disclosure, the charging base may include a main body, a strip-shaped member, and an electrical contact terminal, and the electrical contact terminal is arranged close to the charging interface of the main body. It should be noted that the electrical contact terminal of the present disclosure protrudes from the charging base and is used to realize the electrical connection between the pool device and the charging base. Specifically, the charging base of the present disclosure can be designed to include a main body part and a strip-shaped member and an electrical contact terminal installed thereon, and the main body part is equipped with a charging interface. In order to achieve efficient and stable power transmission, the electrical contact terminal formed by bending the strip-shaped member is carefully arranged at a position close to the charging interface to ensure accurate alignment and contact when connecting with the pool device. At the same time, the area of the electrical contact terminal formed by bending and the charging structure forms a point contact due to the strip-shaped member, thereby realizing reliable power transmission.

[0028] In the present disclosure, the charging interface of the main body part in the charging base can be a magnetic interface or a non-magnetic interface. When the charging interface is a magnetic interface, the magnetic interface automatically aligns with the electrical contact terminal through the attraction of the magnet, which not only simplifies the connection process and improves the user experience, but also provides better waterproof and dustproof performance in an environment with more moisture or dust, and prolongs the service life of the charging base. When the charging interface is a non-magnetic interface, the production cost is low, and high-level durability and reliability can also be achieved. The specific style of the charging interface is not limited here.

[0029] The pool device can be electrically connected to the charging base through the electrical contact terminal, which can be realized by setting an electrical contact metal plate.

[0030] In an exemplary preferred embodiment, the charging base can be the charging base of a pool cleaning robot. The pool device can be a pool cleaning robot.

[0031] As Figure 1 shown, the charging base includes a main body part, a strip-shaped part, and two electrical contact points (i.e., the electrical contact terminals of the present disclosure). These contact points are strategically placed at appropriate positions on the base to facilitate precise docking with the pool cleaning robot. Directly below the electrical contact points is connected a charging interface, which ensures the directness and efficiency of power transmission. Below the pool cleaning robot are two electrical contact metal plates. When the pool cleaning robot returns to the charging base, the electrical contact metal plates of the pool cleaning robot will closely fit with the electrical contact points on the charging base, thereby establishing a stable electrical connection and conducting the circuit, enabling the pool cleaning robot to be charged.

[0032] In the present disclosure, what is improved is the electrical contact terminals provided on the charging base. Hereinafter, the specific characteristics of the electrical contact terminals of the charging base provided by the present disclosure will be specifically described.

[0033] First, Figure 2 is a schematic diagram of the electrical contact terminals of an existing charging base. As Figure 2 shown: Existing electrical contact terminals are all obtained by stamping bumps on metal sheets, and the electrical contact points also need to be compound-plated to prevent electrolysis, which will cause problems such as complex processes, high production costs, and material waste.

[0034] Therefore, the present disclosure provides a charging base, Figure 3 which is a schematic diagram of the charging base provided by an embodiment of the present disclosure. As Figure 3 shown, the charging base in the present disclosure includes a strip-shaped part and electrical contact terminals, and the design of the electrical contact terminals of the present disclosure adopts an innovative structure, that is, a protruding part formed by bending the strip-shaped part, protruding from the plane of the charging base. This design not only makes full use of the physical properties of the material but also takes into account the performance strength, and can achieve the stability and reliability of the electrical contact terminals under multiple uses and long-term operation. It is also specifically pointed out in the present disclosure that the electrical contact terminals are composed of slow electrolysis materials. Slow electrolysis materials refer to metals or alloys with high corrosion resistance in an electrolyte environment. Such materials can effectively slow down the speed of electrochemical reactions, prevent the electrical contact terminals from being corroded due to electrolysis during the electrical connection process, thereby extending their service life and ensuring the quality of electrical contact, especially suitable for the pool environment.

[0035] In the present disclosure, an exemplary preferred slow electrolysis material may be a titanium alloy material. Titanium alloy materials have high strength, high plasticity and high toughness, which makes it not easy to deform or break when subjected to external forces, thereby ensuring the stability and reliability of the electrical contact terminals during long-term use. And titanium alloys have excellent corrosion resistance, especially in harsh environments such as moisture and salt spray, which can reduce poor contact problems caused by corrosion. Of course, in the present disclosure, the slow electrolysis material can also be at least one slow electrolysis material such as copper wire, tin-copper wire, nickel-cobalt wire, etc., which can be flexibly adjusted as needed, and no specific restrictions are made here.

[0036] In the present disclosure, the bending angle of the protruding part of the strip can be flexibly adjusted according to the actual interface space, and theoretically should be less than 150 degrees. In this way, not only can the space be maximized by finely adjusting the bending angle to avoid interference or conflict with other components, but also, since the bending angle affects the formed electrical contact area, a reasonable bending angle design can also help optimize the electrical connection performance and slow electrolysis ability, so that the strip can maintain stable characteristics in different application environments.

[0037] In an exemplary preferred embodiment, the bending angle of the present disclosure can be an acute angle (i.e., less than 90 degrees). The design of the acute angle bend helps to improve the convenience of inserting and removing the strip, especially in a narrow or angle-restricted installation position. At the same time, the electrical contact area formed by the acute angle bend is smaller. This design helps to improve the tightness and stability between the strip and the interface, improve the reliability of electrical conduction, and effectively slow down electrolysis.

[0038] In the present disclosure, in addition to the electrical contact terminals (i.e., the protruding parts formed by bending the strip), the entire strip can also be made of a slow electrolysis material. Generally speaking, the entire strip, whether it is the straight part or the part bent into a hook for electrical connection, can be uniformly made of a slow electrolysis material. In this way, the overall performance and reliability of the component can be improved, the manufacturing process can be simplified, and the production cost can be reduced. It should be noted that the shape of the strip is not limited here. The cross-section of the strip includes but is not limited to at least one of the following: rectangle, circle, polygon. A rectangular cross-section may be more suitable for occasions that require higher structural strength and stability. A circular cross-section may have better fluidity and processability and is easy to form a smaller electrical contact area. The strip with a polygonal cross-section combines the characteristics of a rectangle and a circle, which can not only provide sufficient structural strength and stability but also have good processability and fluidity. Through changing the number of sides and angles, the polygonal design can achieve customized shape matching and is suitable for complex application scenarios that need to cooperate with specific interfaces or structures. However, it should be noted that the present disclosure is not limited to these three shapes, and the cross-section design of the strip can be flexibly adjusted according to actual needs. In special scenarios, the cross-section of the strip can also be other shapes, such as an ellipse or even an irregular shape. The design of these special shapes is often to meet specific performance requirements or space limitations.

[0039] In the present disclosure, when the upper surface of the strip is a plane, the cross-sectional area of the bent protruding part (i.e., the electrical contact terminal) theoretically can be no more than 2.5 square millimeters. This is because when the upper surface of the strip is a plane, the contact area will become larger, which will lead to problems such as poor contact or increased contact resistance. At the same time, if the contact area is too large, the conductive spots will also become larger, accelerating the occurrence of electrolysis. The size of the cross-sectional area directly affects the electrical conductivity of the strip. If the cross-sectional area is too small, the conductive current may be limited, resulting in the inability to meet the required current transmission requirements. If the cross-sectional area is too large, although the conductivity will increase, it may also increase the risk of electrolysis. Especially in applications involving electrolytes or corrosive environments, a too large cross-section is more likely to be affected by electrolysis, leading to material corrosion, performance degradation, or even failure. In summary, based on the above considerations, the present disclosure proposes that the cross-sectional area can theoretically be no more than 2.5 square millimeters. Of course, this principle is not absolute and can be flexibly adjusted according to specific application scenarios and requirements.

[0040] In the present disclosure, the strip needs to be fixed in the charging base so that the bent protruding part (i.e., the electrical contact terminal) of the strip can make normal electrical connections. The following specifically describes the possible implementation methods for fixing the strip.

[0041] The strip-shaped component can be directly fixed on the charging base, and can be used in combination with an elastic device to achieve better connection stability and adaptability. Their combined use can absorb and relieve the impact force generated by at least one of plugging and unplugging, vibration, etc., and protect the charging interface and the strip-shaped component from damage.

[0042] Specifically, the first end of the strip-shaped component can be directly fixed on the charging base, while the second end of the strip-shaped component can be biased by an elastic device. This design allows the strip-shaped component to have a certain degree of flexibility while maintaining a certain rigidity. The elastic device can provide an elastic pressure for the electrical contact terminal facing the pool device, and this pressure helps to ensure good contact between the electrical contact terminal and the pool device, and can effectively reduce the risk of poor contact even in the case of plugging and unplugging or vibration.

[0043] It should be noted that the elastic force provided by the electrical contact terminal of the elastic device and the direction of the electrical contact terminal facing the pool device are the same. In this way, when the elastic device stretches, it can apply pressure along the same direction as the electrical contact terminal. This consistent direction can ensure sufficient contact pressure between the electrical contact terminal and the pool device, thereby improving the connection stability and reliability. Sufficient contact pressure also helps to reduce the resistance and heat generated due to poor contact, and protects the strip-shaped component from damage. Of course, the elastic device of the present disclosure includes but is not limited to at least one of the following: spring, elastic sheet. The present disclosure is not limited to these two elastic devices. In special scenarios, it can also be an elastic device such as a pneumatic component or a hydraulic component, which can be flexibly adjusted according to actual needs.

[0044] The strip-shaped component can also be indirectly fixed on the charging base by using a fixing component, which can bring higher flexibility and stability. Especially when the shape of the charging interface is irregular, the strip-shaped component requires a fixing component to be fixed.

[0045] Specifically, the first end of the strip-shaped component can be connected to the first end of the fixing component, and the second end of the fixing component can be fixed on the charging base. Among them, the specific shape of the fixing component can be flexibly adjusted according to the actual operating space, and is not limited here.

[0046] In an exemplary preferred embodiment, Figure 4 is a longitudinal sectional view of the charging base provided by the embodiment of the present disclosure. As Figure 4 shown:

[0047] In Figure 4 it can be seen that the electrical contact terminal is the part where the strip-shaped component bends and protrudes from the plane of the charging base, and the first end of the strip-shaped component can be directly fixed on the charging base, or can be fixed by using Figure 4The fixing member in it is used for fixing. The specific shape of the fixing member can be flexibly adjusted according to the actual operating space. And the second end of the strip-shaped member can be connected to the spring. In this way, through the combined use of the strip-shaped member and the spring, it can ensure that there is a certain pressure between the electrical contact points on the charging base (such as the charging base) and the electrical contact pieces on the pool equipment (such as: pool cleaning robot), guaranteeing the reliability of charging.

[0048] In summary, the strip-shaped member can be flexibly adjusted and selected to be directly or indirectly fixed on the charging base according to actual needs. This flexibility enables the strip-shaped member to adapt to different application scenarios and installation environments, thus providing a better charging solution.

[0049] In the present disclosure, for the fixing of the strip-shaped member on the charging base, whether it is directly fixed or indirectly fixed, the forms of fixing include but are not limited to at least one of the following: bolts, buckles. Specifically, bolt fixing is a mechanical connection method. Through the cooperation of bolts and nuts, the strip-shaped member is firmly fixed on the charging base. This fixing method has the advantages of simple structure, strong load-bearing capacity, easy disassembly and reinstallation, etc. In practical applications, appropriate bolt specifications, materials, and corresponding pre-tightening forces can be selected according to needs to ensure the reliability and stability of the connection. And buckle fixing is a more convenient fixing method, usually realizing the connection between the strip-shaped member and the charging base through the elastic deformation of the buckle member. Buckle fixing has the advantages of quick installation, easy disassembly, and no need for additional tools, and is especially suitable for application scenarios where the strip-shaped member needs to be frequently replaced or adjusted. In addition, buckle fixing can also reduce the space occupied by the connection part, making the overall structure more compact.

[0050] In the present disclosure, at least one of the size of the electrical contact terminal, the bending angle of the strip-shaped member, etc. can be determined based on the actual interface space. Taking the part of the strip-shaped member protruding from the outer contact plane (i.e., the electrical contact terminal) being able to contact the pool equipment as the benchmark, it can be further flexibly adjusted on this basis, and there is no limitation here.

[0051] The above are only the preferred embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present disclosure shall be included within the protection scope of the present disclosure.
