Description

Technical Field

[0001] This invention relates to the field of robotics, and more specifically, to a charging station and a lawn mowing device. Background Technology

[0002] To meet the demand for greater convenience, some mobile robotic devices, such as lawnmowers or sweepers, have been developed into automatically rechargeable robotic devices. When the battery level is below a threshold, the robotic device will activate a low battery warning and plan a path to automatically return to the charging station for charging, without the need for a physical cable connection.

[0003] In related technologies, when a robot returns to a charging station for charging, due to differences in the robot's movement path, there may be misalignment between the robot's charging interface and the charging contacts. The charging contacts may come into contact with the edge of the opening of the robot's charging interface, causing the robot to get stuck or stop, and thus preventing timely charging. Summary of the Invention

[0004] The purpose of this invention is to provide a charging pile and a robot that facilitates the adaptive docking of the robot's charging interface and charging contacts, reduces the risk of the charging mechanism pressing against and rubbing against the guide under external force, and achieves the goal of fast charging of the robot to be charged, thereby improving charging efficiency.

[0005] A first aspect of the present invention provides a charging pile, the charging pile comprising: A housing having an opening; Guide components are disposed within the housing; A charging mechanism is slidably disposed within the housing along the guide member, the charging mechanism including a charging contact, a portion of which protrudes from the opening; An elastic element, one end of which is connected to the housing and the other end of which is connected to the charging mechanism, slides along the guide member, which can drive the charging contact to move at the opening along the sliding direction of the charging mechanism, and cause the elastic element to elastically deform along the sliding direction of the charging mechanism. A limiting bracket is provided, which is connected to the housing, and the two ends of the limiting bracket correspond to the charging mechanism to restrict the charging mechanism from moving toward the limiting bracket.

[0006] In one possible embodiment of the present invention, the charging mechanism further includes a charging bracket, which is sleeved on the guide member along a first direction, and the charging contacts are disposed on the charging bracket along a second direction. The first direction and the second direction are perpendicular to each other, and the opening extends along the first direction.

[0007] In one possible embodiment of the present invention, there are two guide members, which are arranged in parallel within the housing. The charging bracket has connecting portions at opposite ends along a third direction, and each connecting portion is fitted onto one of the guide members. The third direction is perpendicular to the first direction and the second direction, respectively.

[0008] In one possible embodiment of the present invention, the number of elastic elements is at least two, the two elastic elements are sleeved on the same guide member, the two elastic elements are respectively located on opposite sides of the connecting portion along the first direction, and each elastic element abuts between the connecting portion and the housing.

[0009] In one possible embodiment of the present invention, the connecting portion has a through-hole along the first direction, and each of the guide members passes through the through-hole.

[0010] In one possible embodiment of the present invention, the connecting hole is a stepped hole; Along the first direction, one end of the elastic member abuts against the stepped position of the stepped hole, and the other end of the elastic member is connected to the housing.

[0011] In one possible embodiment of the present invention, at least two first fixing parts are provided inside the housing, one end of the guide is connected to one of the first fixing parts, and the other end of the guide is connected to the other first fixing part; One end of the elastic element abuts against the stepped position of the stepped hole, and the other end of the elastic element is connected to the first fixing part.

[0012] In one possible embodiment of the present invention, the two ends of the limiting bracket along the third direction correspond to the charging bracket to restrict the movement of the charging bracket along the third direction, and the charging bracket is located between the housing and the limiting bracket. In the second direction, there is a gap between the limiting bracket and the charging bracket; The third direction is perpendicular to both the first direction and the second direction.

[0013] In one possible embodiment of the present invention, a guide groove is provided inside the housing, and a boss is provided on the side of the charging bracket near the opening, the boss slidingly engaging with the guide groove.

[0014] A second aspect of the present invention provides a lawn mowing device, including a lawn mowing robot and a charging pile as described in any of the above embodiments. The lawn mowing robot is provided with a charging interface, and the opening of the charging interface is provided with a guide surface. The guide surface is in the shape of a trumpet that expands from the inside to the outside, and the guide surface can guide the charging contacts to be inserted into the charging interface.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention provides a charging pile and lawn mowing equipment, in which a guide is installed inside the housing, and the charging mechanism is slidably disposed inside the housing. The guide guides the movement path of the charging mechanism. As the robot to be charged gradually approaches the charging contact, if there is a misalignment between the charging interface of the robot to be charged and the charging contact, the robot will press against the charging contact and drive the charging mechanism to slide relative to the guide. The charging contact moves with the sliding direction of the charging mechanism, causing the charging mechanism to compress the elastic element, causing the elastic element to elastically deform along the sliding direction of the charging mechanism. Under the elastic action of the elastic element, the charging contact will gradually return to its original position, thereby providing a certain adjustment space between the charging contact and the robot's charging interface, so as to facilitate the adaptive docking of the robot's charging interface and the charging contact. The limiting bracket restricts the movement of the charging mechanism toward the limiting bracket, reducing the situation where the charging mechanism presses against the guide and rubs against the guide under the action of external force, thus affecting the smooth sliding of the charging mechanism. This achieves the purpose of fast charging of the robot to be charged, thereby improving charging efficiency. Attached Figure Description

[0025] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] In related technologies, mobile robotic devices such as lawnmowers or sweepers have been developed into automatically rechargeable robots to meet the demand for greater convenience. When the battery level falls below a threshold, the robot activates a low-battery warning and plans a path to automatically return to the charging station for recharging, eliminating the need for physical cables. However, when returning to the charging station, due to variations in the robot's movement path, there is a possibility of misalignment between the charging interface and the charging contacts. The charging contacts may come into contact with the edges of the charging interface opening, such as the left or right outer edges, causing the robot to get stuck or stop, preventing timely charging.

[0027] Please refer to Figure 1 and Figure 2As shown, an embodiment of this application provides a charging pile 100, which provides a position-adjustable charging contact 132. Correspondingly, a robot using the charging pile 100 for charging has a guide surface 211 at the opening 111 of the charging interface 210 to guide the charging contact 132 to slide along the guide surface 211 into the charging interface 210.

[0028] Specifically, in combination Figure 2 and Figure 3 As shown, the charging pile 100 includes a housing 110, a guide member 120, a charging mechanism 130, an elastic member 140, and a limiting bracket 150. An opening 111 is provided on the housing 110. The guide member 120 is disposed within the housing 110. The charging mechanism 130 is slidably disposed within the housing 110 along the guide member 120. The charging mechanism 130 includes a charging contact 132, a portion of which protrudes from the opening 111, extending beyond the housing 110 through the opening 111. One end of the elastic member 140 is connected to the housing 110, and the other end is connected to the charging mechanism 130. The charging mechanism 130 slides along the guide member 120, causing the charging contact 132 to move along the sliding direction of the charging mechanism 130 at the opening 111, and causing the elastic member 140 to elastically deform along the sliding direction of the charging mechanism 130, thus moving the charging mechanism 130 during the resetting process.

[0029] In this embodiment, as Figure 4As shown, the guide member 120 is installed inside the housing 110, and the charging mechanism 130 is slidably disposed inside the housing 110. The guide member 120 guides the movement path of the charging mechanism 130. As the robot to be charged gradually approaches the charging contact 132, if there is a misalignment between the charging interface 210 of the robot to be charged and the charging contact 132, the guide surface 211 at the opening 111 of the charging interface 210 of the robot to be charged will press against the charging contact 132 and drive the charging mechanism 130 to slide relative to the guide member 120. This causes the charging mechanism 130 to compress or stretch the elastic element 140, and the charging contact 132 moves in the sliding direction of the charging mechanism 130 until the robot's charging interface 210 and the charging contact 132 are adaptively connected, i.e., the charging contact 132 is inserted into the robot's charging interface 210. This avoids the situation where the robot's charging interface 210 and the charging contact 132 cannot connect and get stuck, saving the need for repeated connections between the robot and the charging contact 132. During the process, the limiting bracket 150 restricts the movement of the charging mechanism 130 toward the limiting bracket 150, reducing the friction between the charging mechanism 130 and the guide member 120 under external force. The charging mechanism 130 can slide smoothly. For example, when there is a certain misalignment between the charging contact 132 and the charging interface 210, the guide surface 211 of the charging interface 210 will gradually approach the charging contact 132 and press against the charging contact 132, causing the charging contact 132 to generate a force along the second direction Y. The charging contact 132 will drive the charging mechanism 130 to press against the guide member 120. There may be friction between the charging mechanism 130 and the guide member 120. The limiting bracket 150 restricts the movement of the charging mechanism 130, reducing the friction between the charging mechanism 130 and the guide member 120, allowing the charging mechanism 130 to slide relatively smoothly along the guide member 120, achieving the purpose of fast charging of the robot to be charged, thereby improving charging efficiency.

[0030] When the robot to be charged gradually approaches the charging contact 132, even if there is a misalignment between the robot's charging interface 210 and the charging contact 132, when the guide surface 211 at the opening 111 of the robot's charging interface 210 presses against the charging contact 132, the charging mechanism 130 can be flexibly moved along the guide path of the guide member 120 through the charging contact 132, so as to realize the adaptive position adjustment of the charging contact 132, thereby adapting the charging contact 132 to the robot's charging interface 210 for docking, avoiding the situation where the robot's charging interface 210 cannot dock due to misalignment.

[0031] It is understood that in some embodiments, the charging interface 210 of the robot to be charged has a large diameter. When there is a slight misalignment between the charging interface 210 and the charging contact 132, the robot to be charged gradually approaches the charging contact 132. The guide surface 211 at the opening 111 of the robot's charging interface 210 presses against the charging contact 132, which can also allow the charging contact 132 to slide into the charging interface 210 along the guide surface 211, thereby achieving a compatible connection between the charging contact 132 and the charging interface 210.

[0032] refer to Figure 1 and Figure 2 As shown, the charging pile 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other. For example, the first direction X refers to the width direction of the charging pile 100, the second direction Y refers to the length direction of the charging pile 100, and the third direction Z refers to the height direction of the charging pile 100. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the various parts of the charging pile 100 and should not be construed as limitations on this application.

[0033] In one embodiment, alternatively, such as Figure 3 and Figure 4 As shown, the charging mechanism 130 also includes a charging bracket 131. The charging bracket 131 is sleeved on the guide member 120 along the first direction X, and the charging contact 132 is disposed on the charging bracket 131 along the second direction Y. The first direction X and the second direction Y are perpendicular to each other, and the opening 111 extends along the first direction X, so that the force on the charging bracket 131 is more even and the charging contact 132 is prevented from getting stuck during the movement. By determining the setting direction of the guide member 120 and the charging contact 132, the charging contact 132 has a certain adjustment range. The movement direction of the charging contact 132 is consistent with the movement direction of the guide member 120, which improves the adjustment flexibility of the charging contact 132.

[0034] When the guide surface 211 at the opening 111 of the robot charging interface 210 presses against the charging contact 132, the charging contact 132, after being pressed, can drive the charging mechanism 130 to move along the first direction X. Since the charging contact 132 extends along the second direction Y, the charging contact 132 is used to dock with the robot's charging interface 210. The movement of the charging contact 132 can compensate for the misalignment deviation in the extension direction perpendicular to the charging contact 132, further reducing the docking difficulty and improving the docking efficiency and docking success rate.

[0035] For example, the charging contact 132 is a columnar or rod-shaped structure. For instance, the charging contact 132 can be oriented in the second direction Y towards a position far from the housing 110 to meet the charging needs of different types of electrical appliances. In some electrical appliances, the charging interface 210 is not located on the outermost side of the appliance, but is at a certain distance from it. The charging contact 132 extends in the second direction Y away from the housing 110, allowing the charging contact 132 to contact the charging part.

[0036] The charging bracket 131 has a plate-like or block-like structure and is relatively thin, so that it can be installed inside the housing 110 and reduce space occupancy.

[0037] Optionally, such as Figure 2 and Figure 6 As shown, there are two charging contacts 132, both connected to one side of the charging bracket 131. The two charging contacts 132 are arranged in parallel, which adapts to the robot's dual-interface charging requirements, enabling simultaneous dual-channel charging. This enhances the stability of the charging process, preventing charging interruptions or failures due to poor contact of a single charging contact 132, further improving charging efficiency and reliability. The parallel arrangement of the two charging contacts 132 ensures synchronized adjustment, guaranteeing docking with the robot's dual charging ports, thereby reducing docking difficulty and improving docking efficiency.

[0038] Optionally, refer to Figure 3 As shown, there are two guide members 120, which are arranged parallel to each other within the housing 110. The charging bracket 131 has connecting portions 134 at opposite ends along the third direction Z. Each connecting portion 134 is fitted onto one guide member 120, meaning one guide member 120 passes through one connecting portion 134 of the charging bracket 131. The connecting portions 134 move relative to the guide members 120, improving the guiding accuracy of the charging mechanism 130, ensuring the charging contact 132 has sufficient space for movement, and ensuring the charging mechanism 130 always moves smoothly along the first direction X. This ensures the effectiveness of the adjustment of the charging contact 132, preventing the charging contact 132 from shifting or misaligning due to the torsion of the charging mechanism 130, ensuring a high docking success rate, and improving the practicality of the charging pile 100. For example, the guide member 120 can be a columnar structure.

[0039] For example, in combination Figure 3 and Figure 4 As shown, the two guide members 120 are arranged in parallel, and the two guide members 120 correspond one-to-one with the two connecting parts 134 to form a double guide structure, which improves the stability and guiding accuracy of the charging mechanism 130 during movement and prevents the charging mechanism 130 from twisting or tilting during movement.

[0040] In one embodiment, alternatively, such as Figure 5 As shown, there are at least two elastic elements 140, which are sleeved on the same guide member 120. Along the first direction X, the two elastic elements 140 are located on opposite sides of the connecting portion 134, and each elastic element 140 abuts against the connecting portion 134 and the housing 110. That is, one guide member 120 is provided with two elastic elements 140, located at opposite ends of the connecting portion 134. The connecting portion 134 is located in the middle of the guide member 120. Regardless of whether the charging mechanism 130 moves to either side along the first direction X, one elastic element 140 will be compressed, and the other elastic element 140 will be stretched. The two elastic elements 140 provide elasticity, ensuring that after the robot finishes charging and the charging contact 132 moves out of the charging interface 210, the bidirectional elastic structure can drive the charging mechanism 130 to return to its initial position. The charging contact 132 always extends along the second direction Y, facilitating the robot to reconnect to the charging contact 132 for charging, thereby improving the user experience.

[0041] The elastic element 140 is used to achieve the elastic reset of the charging mechanism 130. That is, the elastic element 140 can drive the charging mechanism 130 and the charging contact 132 to automatically reset to the initial position through its own elastic deformation. The elastic force of the elastic element 140 can also make the charging contact 132 maintain a stable contact pressure with the robot charging interface 210, ensuring the stability of the circuit connection during charging and improving the reliability of the charging process. The elastic element 140 can also buffer the impact force of the guide surface 211 at the opening 111 of the robot's charging interface 210 on the charging contact 132, playing a buffering role, reducing the wear or damage of components, and extending the service life of components.

[0042] For example, there are four elastic elements 140, and every two elastic elements 140 correspond to one guide element 120. The elastic element 140 can be a return spring or a constant pressure spring.

[0043] Optionally, such as Figure 5 As shown, the connecting part 134 has a through connecting hole 1341 along the first direction X. Each guide member 120 passes through the connecting hole 1341. The connecting part 134 has a through connecting hole 1341, which provides a coaxial mounting reference position for the guide member 120. This constrains the guide member 120 from radial offset or misalignment, simplifies the alignment assembly process, ensures the coaxiality of the guide member 120 and the connecting part 134, and improves the alignment accuracy.

[0044] Further, refer to Figure 5As shown, the connecting hole 1341 is a stepped hole. Along the first direction X, one end of the elastic member 140 abuts against the stepped position of the stepped hole, and the other end of the elastic member 140 is connected to the housing 110. The stepped position of the stepped hole forms an axial limiting structure, which limits the elastic member 140 to the force and expansion along the first direction X, eliminating the need for component assembly and avoiding the elastic member 140 from being misaligned or eccentrically discontinuous.

[0045] Optionally, refer to Figure 4 As shown, at least two first fixing parts 112 are provided inside the housing 110. One end of the guide member 120 is connected to one of the first fixing parts 112, and the other end of the guide member 120 is connected to the other first fixing part 112. One end of the elastic member 140 abuts against the stepped position of the stepped hole, and the other end of the elastic member 140 is connected to the first fixing part 112. The first fixing part 112 facilitates the assembly and disassembly of the guide member 120. The first fixing part 112 can position and fix both ends of the guide member 120, ensuring the assembly and positioning of the guide member 120, preventing the guide member 120 from loosening, ensuring the guiding accuracy of the guide member 120, and providing support for the relative movement of the charging mechanism 130. The first fixing part 112 receives the reverse support force at the end of the elastic member 140. The first fixing part 112 and the stepped position of the stepped hole form a bidirectional force-bearing point. The elastic member 140 can be limited and positioned through the stepped hole, which regulates the force-bearing guide trajectory of the elastic member 140 and avoids radial deformation and displacement of the elastic member 140.

[0046] For example, such as Figure 4 As shown, two elastic elements 140 correspond to one guide element 120. A first limiting step 1342 and a second limiting step 1343 are respectively provided at the opening positions of the opposite ends of the stepped hole along the first direction X. One elastic element 140 is engaged with the first limiting step 1342, and the other elastic element 140 is engaged with the second limiting step 1343.

[0047] In one embodiment, optionally, combining Figure 3 and Figure 4As shown, the limiting bracket 150 corresponds to the charging bracket 131 at both ends along the third direction Z, thereby restricting the movement of the charging bracket 131 along the third direction Z. A gap exists between the limiting bracket 150 and the charging bracket 131 in the second direction Y. The limiting bracket 150 can limit the movement of the charging bracket 131 in both the second direction Y and the third direction Z, preventing misalignment of the charging contact 132 due to displacement of the charging bracket 131, and further improving the stability of the structure. The charging bracket 131 is located between the housing 110 and the limiting bracket 150. The gap between the limiting bracket 150 and the charging bracket 131 provides a certain amount of movement space for the charging bracket 131, preventing friction between the limiting bracket 150 and the charging bracket 131 from affecting the relative sliding of the charging bracket 131, allowing the charging contact 132 a certain adjustment space and improving docking flexibility.

[0048] Among them, such as Figure 7 As shown, when there is a certain misalignment between the charging contact 132 and the charging interface 210, the guide surface 211 of the charging interface 210 will gradually approach the charging contact 132 and press against the charging contact 132, causing the charging contact 132 to generate a force along the second direction Y. The limiting bracket 150 can restrict the charging bracket 131 from displacing or shifting along the second direction Y. Under the action of external force, the charging bracket 131 will press against the guide member 120. The connecting hole 1341 of the charging bracket 131 and the guide member 120 will generate a large friction force. The limiting bracket 150 can reduce the friction between the hole wall of the connecting hole 1341 of the charging bracket 131 and the guide member 120, so that the charging bracket 131 can slide smoothly on the guide member 120 through the connecting hole 1341.

[0049] like Figure 4 As shown, the two ends of the limiting bracket 150 are respectively connected to the housing 110. The limiting bracket 150 is approximately a strip-shaped structure, which is used to limit and support the charging bracket 131 to prevent the charging bracket 131 from moving or shifting.

[0050] For example, in combination Figure 6 and Figure 7 As shown, the limiting bracket 150 is provided with a second fixing part 151. The limiting bracket 150 corresponds to the charging bracket 131 through the second fixing part 151 and can abut against the charging bracket 131. The second fixing part 151 is used to limit the charging bracket 131.

[0051] Optionally, refer to Figure 3 and Figure 4As shown, a guide groove 114 is provided inside the housing 110, and a boss 133 is provided on the side of the charging bracket 131 near the opening 111. The boss 133 slides in cooperation with the guide groove 114, so that the charging bracket 131 slides relative to the guide groove 114 along the first direction X through the boss 133. The guide groove 114 can guide and regulate the movement path of the charging bracket 131, and further regulate the movement trajectory of the charging bracket 131.

[0052] Furthermore, a first guide bar and a second guide bar are provided inside the housing 110. The first guide bar and the second guide bar are arranged in parallel, and a guide groove 114 is formed between the first guide bar and the second guide bar to achieve double-sided clamping and limiting of the sliding of the boss portion 133.

[0053] In summary, the guide member 120 of the charging pile 100 is installed inside the housing 110, and the charging mechanism 130 is slidably disposed inside the housing 110. The guide member 120 guides the movement path of the charging mechanism 130. As the robot to be charged gradually approaches the charging contact 132, if there is misalignment or misalignment between the charging interface 210 of the robot and the charging contact 132, the guide surface 211 at the opening 111 of the robot's charging interface 210 will press against the charging contact 132 and drive the charging mechanism 130 to slide relative to the guide member 120. This causes the charging mechanism 130 to compress or stretch the elastic element 140, and the charging contact 132 moves in the sliding direction of the charging mechanism 130 until the robot's charging interface 210 and the charging contact 132 are aligned. The system ensures a smooth connection between the charging interface 210 and the charging contact 132, preventing them from getting stuck and saving time that would otherwise require repeated docking. The limiting bracket 150 restricts the movement of the charging mechanism 130 toward the limiting bracket 150, reducing the likelihood of the charging mechanism 130 pressing against the guide member 120 and rubbing against it under external force. This allows the charging mechanism 130 to slide more smoothly along the guide member 120, achieving the goal of quickly charging the robot and thus improving charging efficiency.

[0054] refer to Figure 1 and Figure 8 As shown, embodiments of the present invention also provide a lawn mowing device, including a lawn mowing robot 200 and a charging station 100 as described in any of the above embodiments. Figure 8As shown, the lawnmower robot 200 is equipped with two charging ports 210, each of which can be plugged into one charging port 210. A guide surface 211 is provided at the opening 111 of the charging port 210. The guide surface 211 is funnel-shaped, expanding outwards, and guides the charging contact 132 to be plugged into the charging port 210. For example, the guide surface 211 has a funnel-shaped or conical structure, and guides the charging contact 132 when it is connected to the charging port 210 for charging. A charging pile 100 is used to charge the lawnmower robot 200. The charging pile 100 can be installed on the ground.
