Description

Technical Field

[0001] This utility model relates to the field of intelligent gardening equipment technology, especially field mowing technology, and more specifically, to a charging component and a mowing robot. Background Technology

[0002] Against the backdrop of booming technological innovation and high-end manufacturing, the robotics industry has undoubtedly become a global focus. Specifically in the field of lawn mowing, lawnmowing robots are widely used in lawn trimming and maintenance. Existing lawnmowing robots possess a variety of advanced functions, greatly facilitating lawn maintenance. They feature automatic walking capabilities, allowing them to operate autonomously on lawns along preset paths without manual control; they are equipped with collision avoidance sensors to effectively prevent collisions with surrounding obstacles, ensuring operational safety; they also have a line-avoidance mechanism, enabling them to work within a limited area and ensuring accuracy in the mowing area; and they can automatically return to charging stations to maintain continuous operation. They also have safety detection and battery level monitoring functions, further enhancing the reliability and safety of the equipment, and possess a certain degree of climbing ability. Since robots need to be charged in outdoor environments, the design of charging stations, as the robots' energy replenishment stations, is crucial.

[0003] However, current lawnmower robots still face some unresolved issues in practical use. The most common charging station design on the market uses a large, solid plastic base. Once the robot moves onto the base, its charging device contacts the charging unit located at the front, side, or top of the base. While this design achieves basic charging functionality, it also presents several problems. First, the solid plastic base blocks sunlight, preventing the lawn beneath from growing properly and causing it to wither over time, affecting the overall aesthetics. Second, the large size of this base increases manufacturing costs and places certain demands on processing technology. Furthermore, existing charging station designs need improvement in charging efficiency and intelligence. For example, some charging stations require frequent manual adjustments to the charging equipment or other operations, increasing labor costs.

[0004] For example, Chinese utility model patent CN213990233U, published on May 13, 2022, includes a housing, a walking module mounted on the housing, which drives an automatic walking device to move and steer. The walking module includes a wheel set and a drive motor for driving the wheel set; a boundary detection module for detecting the positional relationship between the automatic walking device and a physical / virtual boundary; an energy module mounted on the housing for providing energy to the automatic walking device; a control module electrically connected to the walking module and the boundary detection module; the automatic walking device travels along the boundary and turns to leave the boundary after the positional relationship is determined by a software algorithm; a charging interface mounted on the housing for charging the energy module; a charging station for docking charging and providing power to the physical boundary; and charging electrodes mounted on the charging station for charging the energy module. Its main purpose is to minimize the base area while ensuring charging success rate and stability, thereby reducing the overall cost of the charging station and significantly reducing its footprint, thus minimizing its impact on the lawn. However, in this solution, when the charging plate and the robot's charging port are at different heights, the charging plate cannot connect with the charging port, which makes it impossible to guarantee the stability of charging.

[0005] Therefore, how to ensure a stable connection between the charging port and the charging post of the lawnmower robot without it coming loose is a technical problem that the industry urgently needs to solve. Utility Model Content

[0006] The present invention aims to overcome the shortcomings of the prior art and provide a charging component and a lawn mowing robot to solve the problem that the charging plate cannot connect with the charging port when the charging port and the charging plate are at different heights, thus failing to guarantee the stability of charging.

[0007] The technical solution adopted by this utility model is to provide a charging component, including a charging port and a charging arm. The charging port is set on the body of the lawnmower robot, and a charging plate is set inside the charging port. The charging plate is rotatably connected to one side of the charging port through a rotating component, so that the charging port can switch between open and closed states. The charging plate is made of conductive material and is electrically connected to the power supply line inside the robot body.

[0008] The charging arm is installed on the base station. The charging arm is made of conductive material, and one end of the charging arm extends into the base station through an opening on the base station and is electrically connected to the power supply line inside the base station. When the end of the charging arm that extends out of the base station is inserted into the charging port and the charging arm abuts against the charging plate, the charging arm and the charging plate establish an electrical connection, so that the base station can charge the device.

[0009] In one embodiment, the base station is provided with multiple charging arms, and the device is also provided with multiple charging ports. The number of charging ports on the device corresponds to the number of charging ports on the base station. When the multiple charging arms on the base station are inserted into the respective charging ports on the device and abut against the charging plates in each charging port, the base station charges the device.

[0010] In one embodiment, the end of the charging arm extending out of the base station is inclined to form a transition slope. The slope of the transition slope is used to contact the swing end of the charging plate, that is, the slope faces the swing end of the charging plate. During the process of the charging arm being inserted into the charging port, the lever arm of the pushing force applied by the charging arm to the charging plate is longer, and the insertion of the charging arm is more "effortless".

[0011] In one embodiment, each charging port is provided with two charging plates, which rotate and open in opposite directions. When the charging arm is inserted into the charging port, the charging arm abuts against both charging plates, so that both sides of the charging arm abut against the charging plates.

[0012] In one embodiment, a torsion spring is connected between the charging plate and the charging port. The torsion spring provides a rotational return force to the charging plate. When the charging arm is inserted into the charging port, the force provided by the torsion spring ensures that the charging arm abuts against the charging plate.

[0013] In one embodiment, a mobile component is installed inside the base station. One end of the charging arm extends into the base station and is connected to the mobile component. The mobile component is used to limit the range of motion of the charging arm so that even when the charging arm and the charging port are at different heights, the charging arm can still be inserted into the charging port and abut against the charging plate.

[0014] In one embodiment, the mobile component includes two mounting bases fixedly disposed inside the base station, with a support rod connected between the two mounting bases. A sleeve is formed at the end of the charging arm near the mobile component, and the sleeve is fitted onto the support rod, allowing the end of the charging arm extending out of the base station to swing around the support rod.

[0015] In one embodiment, the movable component includes a connecting rod fixedly disposed within a base and a spherical connector disposed at one end of the charging arm extending into the base. A spherical sleeve is disposed at the end of the connecting rod away from the base, and a spherical groove is disposed at the end of the spherical sleeve away from the connecting rod. The inner diameter of the spherical groove is adapted to the diameter of the spherical connector, and the opening cross-section of the spherical groove is smaller than the maximum cross-section of the spherical connector to prevent the spherical connector from disengaging from the spherical groove when rotating.

[0016] A lawnmower robot includes a body with a charging port, and a charging arm is provided on a base station for charging the lawnmower robot. The charging port and the charging arm constitute the aforementioned charging component.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The present invention provides a charging component and a lawnmower robot, which allows the charging arm to be inserted into the charging port of the lawnmower robot and abut against the charging plate, thus ensuring the stability of charging. Attached Figure Description

Detailed Implementation

[0028] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0029] Example 1

[0030] like Figure 1-3As shown, this embodiment provides a charging component, including a charging port 400 and a charging arm 500. The charging port 400 is disposed on the body 200 of the lawnmower robot, and a charging plate 300 is disposed inside the charging port 400. The charging plate 300 is rotatably connected to one side of the charging port 400 through a rotating component 700 (the rotating component 700 can be a hinge, pin, etc., obviously depending on the different installation positions of the rotating component 700 relative to the charging port 400, the charging plate 300 can be flipped up, down, left, and right), so that the charging port 400 can be switched between open and closed states. The charging plate 300 is made of conductive material, and the charging plate 300 is electrically connected to the power supply line inside the body 200.

[0031] A charging arm 500 is installed on the base station 100. The charging arm 500 is made of conductive material, and one end of the charging arm 500 extends into the interior of the base station 100 through the movable port 101 opened on the base station 100 and is electrically connected to the power supply line inside the base station 100. When the end of the charging arm 500 extending out of the base station 100 is inserted into the charging port 400 and the charging arm 500 abuts against the charging plate 300, the charging arm 500 and the charging plate 300 establish an electrical connection, so that the base station 100 can charge the body 200.

[0032] In one embodiment, the base station 100 is provided with multiple charging arms 500, and the body 200 is also provided with multiple charging ports 400. The number of charging ports 400 on the body 200 corresponds to the number of charging ports 400 on the base station 100. When the multiple charging arms 500 on the base station 100 are inserted into the respective charging ports 400 on the body 200 and abut against the charging plates 300 in each charging port 400, the base station 100 charges the body 200.

[0033] like Figure 4 As shown, in one embodiment, the end of the charging arm 500 extending out of the base station 100 has an inclined transition slope 501. The slope of the transition slope 501 is used to contact the swing end of the charging plate 300 (i.e., the end of the charging plate 300 away from the rotating component 700, which can swing freely), that is, the slope faces the swing end of the charging plate 300. In this embodiment, during the process of inserting the charging arm 500 into the charging port 400, the lever arm of the pushing force applied by the charging arm 500 to the charging plate 300 is longer, and the insertion of the charging arm 500 is more "effortless".

[0034] In one embodiment, each charging port 400 is provided with two charging plates 300, and the two charging plates 300 are rotated and opened in opposite directions (that is, for each charging plate 300 in the charging port 400, the rotating component 700 is located at the end of the charging plate 300 away from the other charging plate 300). When the charging arm 500 is inserted into the charging port 400, the charging arm 500 abuts against both charging plates 300.

[0035] In one embodiment, a torsion spring is connected between the charging plate 300 and the charging port 400. The torsion spring is used to provide the charging plate 300 with a rotational return force. When the charging arm 500 is inserted into the charging port 400, the force provided by the torsion spring can ensure that the charging arm 500 abuts against the charging plate 300.

[0036] Example 2

[0037] like Figure 4 As shown, a movable component 600 is provided inside the base station 100. One end of the charging arm 500 extends into the base station 100 and is connected to the movable component 600. The movable component 600 is used to limit the range of motion of the charging arm 500.

[0038] like Figure 5-6 As shown, in one embodiment, the mobile component 600 includes two mounting bases 601 fixedly disposed inside the base station 100. A support rod 602 is horizontally / vertically connected between the two mounting bases 601. A sleeve 502 is formed at one end of the charging arm 500 near the mobile component 600. The sleeve 502 is sleeved on the support rod 602, so that the end of the charging arm 500 extending out of the base station 100 can swing around the support rod 602.

[0039] like Figure 7 As shown, in one embodiment, the movable component 600 includes a connecting rod 603 fixedly disposed within the base station 100 and a spherical connector 606 disposed at one end of the charging arm 500 extending into the base station 100. A spherical sleeve 605 is disposed at the end of the connecting rod 603 away from the base station 100, and a spherical groove 604 is disposed at the end of the spherical sleeve 605 away from the connecting rod 603. The inner diameter of the spherical groove 604 is adapted to the diameter of the spherical connector 606, so that the spherical connector 606 and the spherical groove 604 fit together and are wrapped within the spherical sleeve 605. The charging arm 500 can swing within the constraint range of the spherical groove 604, and the opening cross-section of the spherical groove 604 is smaller than the maximum cross-section of the spherical connector 606, preventing the spherical connector 606 from disengaging from the spherical groove 604 when rotating.

[0040] Other solutions are consistent with Embodiment 1 and have the same technical effects as Embodiment 1, and will not be described in detail in this embodiment.

[0041] Example 3

[0042] like Figure 1 As shown, this embodiment provides a lawnmower robot, including a body 200, a charging port 400 on the body 200, and a charging arm 500 on the base station 100 for charging the lawnmower robot. The charging port 400 and the charging arm 500 constitute the aforementioned charging components.

[0043] The charging component and lawnmower robot provided in this embodiment enable the charging arm 500 to be inserted into the charging port 400 of the lawnmower robot and abut against the charging plate 300, thus ensuring the stability of charging.
