Description

A charge electrode subassembly and robot that mows for robot that mows

Technical Field

The application relates to the technical field of intelligent garden operation equipment, in particular to a charging electrode assembly for a mowing robot and the mowing robot.

Background

With the development of intellectualization of various industries, mowers commonly used in the gardening operation equipment industry are gradually developed from manually operated mowers to intelligent mowers (mowing robots) capable of automatically mowing. The mowing robot can mow the lawn in a defined range according to the setting of a user and has the basic characteristic of being capable of automatically walking, so that the mowing robot is relatively power-consuming equipment, and when a mowing task is finished or the electric quantity is insufficient, the mowing robot can be recharged, namely, a charging pile is returned for charging.

At present, most of charging modes adopted in the industry are spring plates and spring mechanisms, in the butt joint process of a mowing robot and a charging pile, the butt joint of a charging pole piece and the spring plates firstly generates contact points at the end parts of the two, and then the mowing robot continuously moves forward for a certain distance, so that the charging pole piece and the spring plates generate complete joint, during the process, the charging pole piece and the spring plates slide in a friction manner, and the charging pole piece and the spring plates are unstable and are disconnected with a charging power supply. In addition, the spring plate and the charging pole piece are easy to generate sparks during friction sliding, the danger coefficient is high, and the phenomenon is very common in products in the current industry. Furthermore, the travel distance between the charging pole piece and the elastic piece is fixed when the mowing robot is recharged, and when the mowing robot walks to the limit position, a few cases can still go forward, hard collision is easy to form, and the charging component is damaged.

Therefore, how to provide a safe and stable charging mechanism for a mowing robot is a technical problem to be solved by the person skilled in the art.

However, one skilled in the art will readily recognize that some of the features may be omitted, or replaced by other elements, materials, or methods in different situations. In some instances, related operations of the present application have not been shown or described in the specification in order to avoid obscuring the core portions of the present application, and may be unnecessary to persons skilled in the art from a detailed description of the related operations, which may be presented in the description and general knowledge of one skilled in the art.

Referring to fig. 1 to 6, a charging electrode assembly, a mowing robot and a charging pile matched with the mowing robot according to an embodiment of the present application are illustrated.

The charging pile 1 comprises a base 11 and a column 13, the base 11 being usable for parking the mowing robot 2, the column 13 comprising a column housing (not marked) and an infrared emitter (not shown) and a charging contact plate 130 arranged inside the column housing. The charging contact 130 includes a portion, such as a charging control circuit, built into the column housing. The charging contact 130 further includes a portion protruding to the column housing where the first and second charging terminals 131 and 132 are located, that is, the first and second charging terminals 131 and 132 protrude. The first charging terminal 131 and the second charging terminal 132 are a positive terminal and a negative terminal for supplying a charging power, respectively. Charging is achieved by interfacing the first and second charging terminals 131 and 132 with a charging electrode assembly of the lawn mowing robot 2.

The mowing robot 2 includes a chassis 20 and a charging electrode assembly 23. In some examples, the mowing robot 2 also includes a road wheel 22, an infrared detection module 28, and some other components. The chassis 20 may be used for mounting or placing functional components such as a cutterhead (not shown), a lifting device, and the like, and walking wheels 22 are mounted on two sides of the chassis 20, so that the chassis 20 is driven to move by walking of the walking wheels.

In the embodiment of the application, the charging electrode assembly 23 is mounted to the chassis 20 in a radial arm manner, and the charging electrode assembly 23 is pushed to rotate by the first charging terminal 131 and the second charging terminal 132 to generate butt joint when the mowing robot 2 is recharged. Specifically, the charge electrode assembly 23 includes a charge plate 230, a rotation shaft 236, and a spring 233. Charging plate 230 includes a charging base 2300, a through hole 2306, a first charging pole piece 2301, and a second charging pole piece 2302. The first charging pole piece 2301 and the second charging pole piece 2302 are fixed to the charging base 2300 and are exposed to the front surface of the charging base 2300 (i.e., the surface facing the charging pile 1). The first charging pole piece 2301 and the second charging pole piece 2302 are arranged at intervals, and can be respectively used as a charging positive electrode and a charging negative electrode of the mowing robot 2, and the charging base 2300 can be made of an insulating material. Through-holes 2306 are located on top of charging base 2300, and as an example, through-holes 2306 extend through both left and right sides of charging base 2300. It should be understood that, if the charging base 2300 is a substantially rectangular plate, and the through hole 2306 is located at the top and penetrates the left and right sides thereof, the through hole 2306 may extend along the side length of the rectangle and communicate with the outside at both end positions of the side length. The rotating shaft 236 is connected to the chassis 20, the charging plate 230 is rotatably mounted on the rotating shaft 236 through the through hole 2306, and meanwhile, the spring 233 abuts against the charging plate 230 and provides a reverse thrust when the charging plate 230 rotates, and the reverse thrust is opposite to the thrust of the charging terminal of the charging pile 1 pushing the charging plate 230, so that a balancing effect can be achieved, and the charging plate 230 can keep close contact with the first charging terminal 131 and the second charging terminal 132 in the abutting process.

It can be seen that the charging plate 230 with the first and second charging pole pieces 2301, 2302 is rotatably mounted to the chassis 20 by the rotation shaft 236, and that the charging pole pieces on the charging plate 230 make initial contact with the charging terminals of the charging post 1 when the robot mower 2 is recharged. Along with the forward movement of the mowing robot 2, the charging terminal of the charging pile 1 pushes the charging plate 230 to rotate or rotate around the rotating shaft 236, and meanwhile, the thrust generated by the charging terminal is balanced by means of the reverse thrust provided by the spring 233 for the charging plate 230, so that the charging plate 230 and the charging terminal are continuously and stably attached, the power supply connection between the mowing robot 2 and the charging pile 1 in the butt joint process is continuously uninterrupted, meanwhile, friction sliding between the charging pole piece on the charging plate 230 and the charging terminal of the charging pile 1 is avoided, spark generation is reduced, and charging stability and safety of the mowing robot 2 are improved.

In some embodiments, the spring 233 is a torsion spring. The spring 230 includes an annular portion 2330, a first tail portion 2332 and a second tail portion 2335, the first tail portion 2332 and the second tail portion 2335 are respectively connected to two ends of the annular portion 2330, the annular portion 2330 is sleeved on the rotating shaft 236, and the first tail portion 2332 is abutted to the charging base 2300. The torsion spring is adopted to provide reverse thrust for the charging plate, so that the charging plate is easy to install, the torsion spring can be sleeved on the rotating shaft 236 through the annular portion 2330, and on the other hand, different torsion can be achieved due to different included angles between the first tail portion 2332 and the second tail portion 2335, and different torsion springs can be selected to meet different product requirements. The second tail portion 2335 may abut against the inner wall of the cabinet 200, or may be in a free state.

In some embodiments, the charging plate 230 further includes a notch 2303 and a groove 2305, the notch 2303 is located at the top of the charging base 2300, the annular portion 2330 of the spring 233 is located within the notch 2303, the groove 2305 is located at the back of the charging base 2300, and the first tail portion 2332 is located within the groove 2305. The notch 2303 provided at the top of the charging base 2300 cuts the through hole 2306 into two parts, that is, two through holes respectively provided at the left and right sides of the notch 2303, the through hole 2306 is communicated with the notch 2303, the rotation shaft 236 passes through the through hole 2306 and the notch 2303, and the provision of the notch 2303 facilitates placement of a spring, so that the charging electrode assembly 23 is more compact as a whole. The groove 2305 may stabilize the position of the first tail portion 2332, further improving the reliability of the charging electrode assembly 23.

As an example, the first charge pole piece 2301 and the second charge pole piece 2302 extend from the top of the charge base 2300 to the bottom of the charge base 2300. The bottom is a relatively closer portion to the ground, and the initial contact of the charging terminal of the charging pile 1 with the charging plate 230 may be a contact with the bottom front surface of the charging base 2300, that is, the initial contact is a point contact, instead of the entire conductive surface of the charging pole piece being in full-face contact with the entire charging terminal. The point contact of the charging plate and the charging pile is kept in the abutting process until the charging plate is changed from the initial vertical state to the abutting in-place state, and the charging plate is not changed into the complete surface contact of the charging plate and the charging pile until the charging plate is in the abutting process, and the conductive pole piece extends from the top to the bottom, so that the state that the power supply between the mowing robot 2 and the charging pile 1 is kept in the abutting process can be ensured. It should be understood that the top and bottom herein refer to opposing areas and not strictly to the fact that the charge pole piece has a completely uniform length or width with the charge base 2300, or that the charge pole piece must reach the edge of the charge base, e.g., the through hole 2306 may be at the top of the charge base 2300 closest to the edge, while the upper edge of the first charge pole piece 2301 may be near and below the through hole 2300.

The mowing robot of the embodiment of the application comprises a chassis 20 and a charging electrode assembly 23, wherein the charging electrode assembly 23 comprises a charging plate 230 and a rotating shaft 236, the charging plate 230 comprises a charging base 2300, a through hole 2306, a first charging pole piece 2301 and a second charging pole piece 2302, the first charging pole piece 2301 and the second charging pole piece 2302 are fixed on the charging base 2300 and are exposed out of the front surface of the charging base 2300, the first charging pole piece 2301 and the second charging pole piece 2302 are mutually arranged at intervals, the through hole 2306 is positioned at the top of the charging base 2300, the rotating shaft 236 is connected to the chassis 20, and the charging plate 230 is rotatably mounted on the rotating shaft 236 through the through hole 2306.

As an example, the chassis 20 includes a case 200, the case 200 includes a window 201, and the charging electrode assembly 23 is mounted inside the case 200 and corresponds to the window 201. The charging electrode assembly 23 is arranged in the case 200, so that the surface charging electrode assembly 23 can be subjected to the loss caused by the influence of environmental weather, and the normal charging operation of the mowing robot can be protected even in rainy days, and accidents caused by rain can not happen. Under the condition that the window 201 can ensure that the charging electrode assembly 23 is built-in, the charging terminal can extend into the machine shell to be in butt joint with the charging pole piece, meanwhile, the charging plate 230 of the charging electrode assembly 23 is opposite to the window 201, the front size of the charging plate 230 is matched with the size of the window 201, and the charging plate 230 can visually fill in the window 201, so that the whole appearance of the mowing robot 2 is smooth and attractive.

In some embodiments, the robot 2 further includes a circuit board base 21, the circuit board base 21 is mounted and fixed to the casing 200, and the charging electrode assembly 23 is mounted to the circuit board base 21. The circuit board base 21 includes a mounting portion 211, and in particular, the mounting portion 211 may be mounting lugs provided on both sides, and the circuit board base 21 may be mounted and fixed to the chassis by some mating mounting structure (not shown) within the chassis 200 through the mounting portion 211.

In some embodiments, the circuit board base 21 further includes a receiving seat 210 and an extension portion 213, the receiving seat 210 is used for placing or mounting the circuit board 27, the extension portion 213 extends from the receiving seat 210 toward the window 201, and the charging electrode assembly 23 is mounted at the end of the extension portion 213 and is spaced apart from the receiving seat 210 by a first distance S. The top of the housing base 210 may be used for mounting the circuit board 27, and the battery pack 25 may be placed under the housing base 210, where the battery pack 25 is clamped between the inner wall of the casing 200 and the housing base 210. The first charge pole piece 2301 and the second charge pole piece 2302 are connected to a circuit board 27, the battery pack 25 is connected to the circuit board 27, and the circuit board 27 may include a control circuit associated with charging, and the battery pack 25 includes a plurality of rechargeable batteries. The charging electrode assembly 23, the circuit board 27 and the battery pack 25 are assembled into a relatively concentrated space through the circuit board base 21, facilitating the layout and design of internal wiring.

Mounting the charging electrode assembly 23 by the outwardly extending lugs allows the charging plate 230 to be clamped between the two opposing first and second lugs 2131 and 2132 without being offset from the corresponding positions of the window 201, improving product reliability.

In some embodiments, the first distance is greater than the top-to-bottom dimension d of the charging base 2300 of the charging electrode assembly 23, so that sufficient space is ensured for the charging plate 230 to rotate from an initial suspended vertical state to a substantially horizontal state, while sufficient travel is maintained to avoid hard-to-hard contact between the charging terminal and the charging pole piece, and wear is reduced.

In some embodiments, the robot lawnmower 2 further includes an infrared detection module 28, the infrared detection module 28 being mounted to the chassis 20 and above the charging electrode assembly 23. The infrared detection module 28 can be used for detecting infrared light emitted by an infrared emitter in the charging pile 1, so that the charging is smoothly performed under the guidance of infrared detection.

Referring to fig. 7 to 9, a recharging process of the mowing robot according to an embodiment of the application is illustrated. First, the mowing robot 2 walks to the charging pile 1 and aligns to the charging position, at this time, the charging pole piece and the charging terminal are not yet butted, and the charging pole piece and the charging terminal are not yet contacted, which can refer to the state shown in fig. 7.

Finally, the mowing robot 2 is charged back in place, and charging is started. The recharging state can be similar to that of fig. 9, or the complete surface contact between the charging pole piece and the charging terminal is generated.

It should be understood that, although the first and second charging terminals 131 and 132 of the charging post 1 are named as "charging terminals", the specific form thereof is not limited to the terminals, but may be a charging pole piece.
