Description

Technical Field

[0001] The utility model relates to the technical field of lawn mowers, in particular to a guided power connection structure, a lawn mower and a lawn mower charging system. Background Art

[0002] With the rapid development of technology, intelligent electric tools and devices play an increasingly important role in our daily lives. From automatic floor-sweeping robots to intelligent lawn mowers, these devices not only improve our work efficiency but also greatly enhance our quality of life. They can automatically perform cleaning or lawn trimming tasks according to a preset schedule and automatically return to the charging cockpit for charging after the tasks are completed, thus achieving true automation and providing convenience for users. However, to ensure the stable operation of these intelligent devices, they require a reliable and stable power connection.

[0003] Nevertheless, the existing power connection structures often have some deficiencies in practical applications. Especially in outdoor environments, these limitations may become more obvious. For example, the variability of outdoor environments may lead to unstable power connections, and adverse weather conditions such as strong winds and heavy rains may also affect the power connection, thus affecting the normal operation of the devices.

[0004] In the usage scenarios of outdoor electric tools such as intelligent lawn mowers, due to cost and technological limitations, their automatic navigation and positioning systems may not achieve extremely high precision. This means that when the lawn mower completes its work and attempts to return to the charging dock, it may be difficult to align the power pins of the charging dock. In addition, lawn mowers usually work in relatively harsh environments, which not only interfere with their positioning systems but may also cause rainwater or other impurities to enter the charging interface, thus triggering short circuits or other electrical faults. Summary of the Utility Model

[0005] In view of the above-mentioned disadvantages of the prior art, the technical problem to be solved by the utility model is to provide a guided power connection structure, a lawn mower and a lawn mower charging system, so as to solve the problems of difficult pin alignment and easy short circuit in the charging structure of the existing lawn mowers.

[0006] To solve the above technical problems, the utility model provides a guided power connection structure for assisting the insertion of power supply pins, including:

[0007] A protective housing, in which two electrode cavities are arranged side by side and separated from each other. Two insertion openings communicating with the electrode cavities are provided on the protective housing, and two wedge-shaped guiding baffles extending towards the inside of the insertion openings are symmetrically arranged on both sides of each insertion opening;

[0008] Two lead springs, the two lead springs are separately arranged in the electrode cavity, the lead spring comprises a fixing portion fixed in the corresponding electrode cavity and two contact portions, one end of the contact portion is respectively connected to the two ends of the fixing portion, the contact portion is bent into an arch structure, the arch structure is symmetrically arranged on the inner side of the insertion port, and the distance between the two arch structures is smaller than the size of the power supply pin;

[0009] When power is needed, the power supply pin and the guided power connection structure approach each other and first contact the corresponding wedge-shaped guide baffle. The power supply pin slides into the insertion port along the wedge-shaped surface of the wedge-shaped guide baffle and is inserted between the two contact portions, respectively abutting against the arch structure. At this time, the connecting spring sheet is stretched open and deformed by the power supply pin, and the contact portions on both sides apply the elastic force required to clamp the power supply pin.

[0010] As a more preferred manner, the other end of the contact portion is elastically overlapped with the inner side of the corresponding wedge-shaped guide baffle, so that when the power supply pin slides into the insertion port along the wedge-shaped surface of the wedge-shaped guide baffle, it can directly contact the contact portion of the guide spring sheet, and the structure is more compact.

[0011] As a more preferred manner, the guided power connection structure further includes a power transmission cable, and the power transmission cable is connected to the fixing portion.

[0012] As a more preferred embodiment, the connecting spring piece further comprises a wiring portion connected to the fixing portion, and the power transmission cable is connected to the connecting spring piece via the wiring portion.

[0013] As a more preferred manner, two drainage holes connected to the electrode cavity are respectively provided at the bottom of the protective shell, and the accumulated water splashed into the electrode cavity can be discharged from the electrode cavity through the drainage holes, thereby reducing the risk of interference of the accumulated water to the system.

[0014] As a more preferred method, the bottom of the protective shell is a drainage slope extending downward and outward to assist drainage. The accumulated water splashed into the electrode cavity will be discharged from the electrode cavity along the drainage slope under the action of gravity, reducing the risk of interference of the accumulated water to the system.

[0015] As a more preferred manner, fixing structures corresponding to the guide springs are respectively arranged in the protection shell, and the fixing parts of the guide springs are fixed in the corresponding electrode cavities through the fixing structures.

[0016] As a more preferred manner, a plurality of limiting structures corresponding to the receiving spring pieces are respectively arranged in the protective shell, and the limiting structures are arranged on the inner side of the arch structure to avoid structural failure caused by excessive deformation of the contact part under abnormal circumstances.

[0017] In order to solve the above problems, the utility model also provides a lawn mower, comprising:

[0018] The above-mentioned guided power connection structure.

[0019] In order to solve the above problems, the utility model also provides a lawn mower charging system, comprising:

[0020] A charging base, wherein the charging base is provided with a power supply pin;

[0021] When the above lawn mower is charged, the lawn mower moves toward the charging seat and utilizes the guided power connection structure to assist the power supply pin to be inserted into the corresponding insertion port.

[0022] As described above, the guided power connection structure, lawn mower and lawn mower charging system of the utility model have the following beneficial effects:

[0023] When the guided power connection structure of the utility model is in use, it is not necessary to require the power supply pin to be directly and accurately aligned with the insertion port. It is only required that the power supply pin and the guided power connection structure are in the process of approaching each other, so that the power supply pin contacts the corresponding wedge-shaped guide baffle, and the power supply pin slides into the insertion port along the wedge-shaped surface of the wedge-shaped guide baffle, and is inserted between the two contact parts, respectively abutting against the arch structure, and at this time, the guide spring piece is stretched open by the power supply pin and deformed, and the contact parts on both sides apply the elastic force required to clamp the power supply pin, so that the power supply line is connected; at the same time, because the two electrode cavities are separated from each other and arranged in the protective shell, compared with the single chamber design, the short circuit risk is greatly reduced, and the guide spring pieces arranged in each electrode cavity clamp the power supply pin from both sides, further ensuring the stability of the connection;

[0024] The lawn mower of the utility model adopts the above-mentioned guided power connection structure, which ensures that when the lawn mower moves toward the power supply pin, the power supply pin only needs to contact the corresponding wedge-shaped guide baffle, so that the power supply pin can slide into the insertion port along the wedge-shaped surface of the wedge-shaped guide baffle, which greatly improves the success rate of circuit connection, reduces the positioning accuracy requirements of the lawn mower, and saves costs; at the same time, the design of the electrode chambers separated from each other greatly reduces the risk of impurities and rainwater entering the electrode chamber and causing short circuits in the harsh use environment of the lawn mower;

[0025] The lawn mower charging system of the utility model meets the requirement of automatically completing charging when the lawn mower is set outdoors, reduces the risk of short circuit, is safer and more reliable, and improves the use experience;

[0026] When in use, the guided power connection structure, lawn mower and lawn mower charging system of the utility model utilize a separately arranged electrode cavity and a wedge-shaped guide baffle to reduce the risk of short circuit, improve the success rate of aligning the lawn mower with the power supply pin, and solve the problems of difficult pin alignment and easy short circuit in the lawn mower charging structure in the prior art.
