Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, and in particular to a charging structure and an intelligent lawnmower. Background Technology

[0002] Smart lawnmowers are widely used in the garden tool market. To enable long-term operation and adapt to large work areas, they are usually equipped with a charging device in the work area. The smart lawnmower can charge and standby at the charging device. When it is needed, the smart lawnmower will automatically drive away from the charging device with the power of the battery pack to mow the grass in the work area.

[0003] Smart lawnmowers and charging devices are generally connected via mechanical interfaces. For example, Chinese patent "CN219576679U" discloses "a charging base station for a smart lawnmower." This charging base station adjusts the position of its upper section according to the different heights of the smart lawnmower to allow the charging connector to directly connect with smart lawnmowers of different sizes without the need for other conductive components. However, because the structure of the charging connector is relatively fixed, the smart lawnmower needs to precisely connect with the connector during charging. This not only results in unstable connections but also makes the operation cumbersome, reducing the convenience of operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a charging structure and an intelligent lawnmower, which solves the problem that existing intelligent lawnmowers require precise docking with the charging docking device of the charging base station during charging, resulting in cumbersome operation and reduced ease of use.

[0005] According to the embodiments of this utility model, the following technical solution is adopted:

[0006] A charging structure for docking with the charging contact piece of a charging base station, comprising:

[0007] The charging unit includes a mounting base and a charging base, with the charging base fastened to the mounting base.

[0008] The drive block and the mounting base are provided with a mounting shaft. The drive block is located on the mounting shaft. The mounting base is provided with an elastic element that abuts against the drive block. The end of the drive block is provided with a charging spring that corresponds to the charging base.

[0009] Specifically, when the charging contact piece abuts against the driving block, the driving block causes the charging spring to dock with the charging base, or when the charging contact piece moves away from the driving block, the charging spring separates from the charging base.

[0010] Preferably, the drive block includes a mounting section disposed on the mounting shaft and a movable section connected to the charging spring, the movable section and the mounting section being connected by an arc segment.

[0011] Preferably, a guide plate is fixedly provided on the side of the charging spring, and the guide plate is disposed between the movable section and the arc section.

[0012] Preferably, the guide plate has several holes.

[0013] Preferably, the elastic element includes a torsion spring, which is sleeved on the mounting shaft and abuts against the mounting base and the drive block.

[0014] Preferably, both the mounting base and the charging base are provided with mounting blocks, and the mounting blocks have mounting holes, with two corresponding mounting holes connected by bolts.

[0015] According to embodiments of this utility model, the following technical solutions are also adopted:

[0016] A smart lawnmower includes a housing and a charging structure with a mounting base disposed on the housing.

[0017] Preferably, the housing has a charging port, and the mounting base is located inside the housing and corresponds to the charging port.

[0018] Preferably, the bottom of the mounting base is provided with several support blocks, and all of the support blocks are connected to the inside of the housing.

[0019] Preferably, the inner side of the housing has a threaded hole corresponding to the mounting hole.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In this solution, when charging the smart lawnmower, the lawnmower is driven to the charging base station. Simultaneously, the charging contact plate of the charging base station presses against the drive block, causing the drive block to rotate around its mounting shaft. This allows the drive block to engage its charging spring with the charging socket of the charging unit, quickly establishing an electrical connection between the smart lawnmower and the charging base station. Furthermore, the large contact area between the drive block and the charging contact plate of the charging base station means that only the two need to touch to charge the smart lawnmower, facilitating operation and connection, and improving charging reliability. After charging is complete, the smart lawnmower can be directly separated from the charging base station, and the drive block automatically resets under the action of the elastic element. The elastic element also provides a certain rebound force to the drive block, ensuring it remains connected to the charging contact plate and guaranteeing charging efficiency.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0030] like Figure 1 and Figure 2 As shown, this embodiment of the present invention proposes a charging structure for docking with the charging contact 201 of the charging base station 2, comprising:

[0031] The charging unit 3 includes a mounting base 301 and a charging base 302, with the charging base 302 fastened to the mounting base 301.

[0032] The drive block 4 and the mounting base 301 are provided with a mounting shaft 404. The drive block 4 is located on the mounting shaft 404. The mounting base 301 is provided with an elastic element that abuts against the drive block 4. The end of the drive block 4 is provided with a charging spring 401 that corresponds to the charging base 302.

[0033] Specifically, when the charging contact 201 abuts against the driving block 4, the driving block 4 causes the charging spring 401 to dock with the charging base 302, or when the charging contact 201 moves away from the driving block 4, the charging spring 401 separates from the charging base 302.

[0034] In this embodiment of the invention, the charging base station 2 is installed in a designated work area, taking care to protect it from rain and sun. The charging base station 2 consists of a base and a protruding seat. The charging contact piece 201 is installed on the protruding seat to facilitate docking with the lawnmower. When the lawnmower needs charging, it is driven onto the base of the charging base station 2, so that the charging part 3 on the lawnmower is in front of the charging contact piece 201. Initially, the drive block 4 is tilted upwards and higher than the charging contact piece 201, but the charging part 3 is lower than the charging contact piece 201. As the lawnmower continues to move, the charging part 3 of the lawnmower gradually moves closer to the charging contact piece 201. The bottom of the drive block 4, with its upward-curving portion, is pressed by the protruding seat of the charging base station 2 and rotates around the mounting shaft 404. This causes the drive block 4 to engage with the charging spring 401 on it, quickly establishing an electrical connection between the smart lawnmower and the charging base station 2 for charging. The charging unit 3 has a large contact area, requiring only the two parts to come into contact to charge the smart lawnmower, facilitating operation and easy connection. Furthermore, the drive block 4, with its elastic element, possesses a certain degree of resilience, ensuring it remains in contact with the charging contact 201 during charging, thus improving charging reliability. After charging, the lawnmower can easily leave the charging base station 2, and the drive block 4 returns to its original position under the action of the elastic element, ready for the next charging cycle. This design is suitable for applications requiring frequent connection and disconnection of the charging link.

[0035] Based on the above solutions, such as Figure 5 As shown, the drive block 4 includes a mounting section 406 located on the mounting shaft 404 and a movable section 405 connected to the charging spring 401. The movable section 405 and the mounting section 406 are connected by an arc section 407. The drive block 4 is composed of the mounting section 406, the movable section 405 and the arc section 407, so that the drive block 4 has an overall arc structure, which can provide a smaller trigger stroke. When the charging spring 401 docks with the charging base 302, the movable section 405 can be connected to the charging contact piece 201 as a whole, ensuring the charging contact area.

[0036] Specifically, such as Figure 6 As shown, a guide plate 402 is fixedly provided on the side of the charging spring plate 401. The guide plate 402 passes through the movable section 405 and the arc section 407. The guide plate 402 can increase the thickness of the driving block 4 without increasing the volume of the driving block 4. The guide plate 402 is directly connected to the charging spring plate 401 and directly docks with the charging contact plate 201, which improves the charging efficiency. When the lawnmower moves, the guide plate 402 is squeezed by the charging base station 2, which can drive the driving block 4 to rotate until the guide plate 402 docks with the charging contact plate 201.

[0037] Meanwhile, the guide plate 402 has several holes 408, and the guide plate 402 can be installed on the drive block 4 by passing bolts through the holes 408, which facilitates assembly and later replacement.

[0038] Specifically, such as Figure 2 and Figure 4 As shown, the elastic element includes a torsion spring 403, which is sleeved on the mounting shaft 404 and abuts against the mounting base 301 and the drive block 4. To facilitate the installation of the elastic element, a torsion spring 403 is used. The torsion spring 403 can be directly sleeved on the mounting shaft 404 without the need for other limiting structures. The torsion spring 403 can limit the drive block 4, while also providing a large rebound force to ensure a certain service life.

[0039] Specifically, such as Figure 3 As shown, both the mounting base 301 and the charging base 302 are provided with mounting blocks 5. The mounting blocks 5 have mounting holes 501, and the two corresponding mounting holes 501 are connected by bolts. The mounting base 301 and the charging base 302 achieve an assembly design under the action of the mounting blocks 5. In the early stage of assembly, it is only necessary to align the corresponding mounting blocks 5 and insert the bolts for quick assembly. In the later stage, it is only necessary to remove the bolts to separate the charging base 302 from the mounting base 301 for maintenance and inspection.

[0040] This utility model embodiment also proposes an intelligent lawnmower, including a housing 1 and the above-mentioned charging structure. The mounting base 301 is disposed on the housing 1. The specific structure of the charging structure is as described in the above embodiment. Since this intelligent lawnmower adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought about by the technical solutions of the above embodiment, which will not be described in detail here.

[0041] Secondly, such as Figure 4 As shown, the housing 1 has a charging port 6, and the mounting base 301 is located inside the housing 1 and corresponds to the charging port 6. By opening the charging port 6, the charging part 3 for charging can be installed inside the housing 1, which not only reduces the size of the entire lawnmower, but also protects the entire charging part 3 with the housing 1, improves the cycle time, and extends the service life.

[0042] Meanwhile, the bottom of the mounting base 301 is provided with several support blocks 303, all of which are connected to the inner side of the housing 1. During charging, the charging contact piece 201 of the charging base station 2 will exert a certain downward pressure on the drive block 4, and this downward pressure will be directly transmitted to the mounting base 301. In the case of frequent charging, in order to prevent the structure of the mounting base 301 from deforming, the support blocks 303 provide an effective support force for the mounting base 301, ensuring the connection strength between the mounting base 301 and the housing 1, ensuring that the mounting base 301 will not deform during multiple charging, and ensuring normal charging operation each time.

[0043] Furthermore, such as Figure 3 As shown, the inner side of the housing 1 is provided with a threaded hole corresponding to the mounting hole 501. In order to facilitate the installation and connection between the mounting base 301 and the housing 1, a threaded hole corresponding to the mounting hole 501 is provided on the housing 1 based on the original mounting hole 501. When assembling the mounting base 301 and the charging base 302, the mounting base 301 is pressed onto the housing 1 and the charging base 302 is fastened onto the mounting base 301. Screws are used for fixed installation, which can realize quick assembly and disassembly and facilitate later maintenance.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
