Description

[Technical Field]

[0001] This utility model relates to the field of intelligent tool technology, and in particular to a compact self-moving device. [Background Technology]

[0002] With the development of smart technology, smart vacuum cleaners and smart lawnmowers, used for indoor environmental cleaning and outdoor garden maintenance respectively, have been widely adopted in households. Among them, the smart lawnmower is a commonly used garden tool for mowing various types of lawns. The main unit of the smart lawnmower is movably connected to a bumper, and a collision detection device is installed between the bumper and the main unit. When the smart lawnmower accidentally collides with an obstacle, the bumper will make contact with the obstacle first to cushion the impact and prevent the main unit from making hard contact with the obstacle. At the same time, the collision detection device is triggered and controls the smart lawnmower to stop moving. This avoids damage to the main unit caused by frequent collisions with obstacles when the smart lawnmower is working in the outdoor garden.

[0003] In existing smart lawnmowers, the connection and limiting structure between the impact plate and the main unit, as well as the charging structure, are all independently installed on the main unit housing, occupying a large amount of space and affecting the installation and layout of other components.

[0004] Therefore, it is indeed necessary to provide an improved self-moving device to overcome the shortcomings of the existing technology. [Utility Model Content]

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a compact self-moving device.

[0006] The present invention solves the existing technical problems by adopting the following technical solution: A self-moving device, comprising: a housing; an energy component for supplying power to the self-moving device, the energy component being installed in the housing; an electrode holder, comprising a base and an electrode plate disposed on the base, the base being connected to the housing, the electrode plate comprising a first mating end electrically connected to a charging device and a second mating end electrically connected to the energy component; a ramming plate movably connected to the housing; the electrode holder further comprising a stop block disposed on the base, wherein, in the front-rear direction of the self-moving device, the stop block is at least partially located behind the ramming plate to prevent the ramming plate from continuing to move backward.

[0007] Furthermore, in a projection plane perpendicular to the front-rear direction of the self-moving device, the orthographic projection of the stop block in the projection plane at least partially coincides with the orthographic projection of the impact plate in the projection plane.

[0008] Furthermore, the stop block is at least partially located on the left-right movement path of the impact plate of the self-moving device.

[0009] Furthermore, the stop block is at least partially located on the movement path of the impact plate in the forward and backward direction of the self-moving device.

[0010] Furthermore, both the electrode sheet and the stop block are integrally injection molded onto the base body.

[0011] Furthermore, the housing includes a first chamber isolated from the external environment, and the seat includes a connecting portion that is sealed to the housing and defines a second chamber. The first chamber communicates with the second chamber, and the first mating end and the stop block are both disposed outside the first chamber and the second chamber.

[0012] Furthermore, the housing includes a first outer shell and a second outer shell connected to the first outer shell and defining the first chamber. A first seal is provided at the connection between the first outer shell and the second outer shell, and a second seal is provided at the connection between the connecting portion and the first outer shell and / or the second outer shell.

[0013] Furthermore, the seat also includes a support portion connected to the connecting portion, and the first docking end and the stop block are both disposed on the support portion. In the height direction of the self-moving device, the first docking end is disposed above the stop block.

[0014] Furthermore, the second mating end is disposed on the connecting portion and located inside the first chamber and / or the second chamber.

[0015] To address the problems of existing technologies, this utility model also provides a self-moving device, comprising: a housing; an energy component for supplying power to the self-moving device, the energy component being mounted on the housing; an electrode holder comprising a base and electrode plates disposed on the base, the base being connected to the housing, the electrode plates being electrically connected to the energy component and a charging device respectively; a collision plate movably connected to the housing; the electrode holder further comprising a stop block disposed on the base, the stop block being at least partially located on the movement path of the collision plate in the front-rear direction of the self-moving device.

[0016] Compared with the prior art, the present invention has the following advantages: The self-moving device includes a housing and an energy component, an electrode holder, and a collision plate mounted on the housing. The electrode holder includes a base and an electrode plate and a stop block disposed on the base. The electrode plate is electrically connected to the energy component and the charging device, respectively. In the front-rear direction of the self-moving device, the stop block is at least partially located behind the collision plate to prevent the collision plate from continuing to move backward. Thus, the stop block, which limits the range of movement of the collision plate in the front-rear direction of the self-moving device, is mounted on the base of the electrode holder. The housing of the self-moving device does not need to provide additional space for mounting the stop block, thereby making the self-moving device structure compact. [Attached Image Description]

Detailed Implementation Methods

[0036] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. In the description of this specification, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0037] The terminology used in this invention is for the purpose of describing specific embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "front," and "rear" that indicate orientation or positional relationship are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0038] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0039] Please see Figures 1 to 4 The image shows a self-moving device according to one embodiment of the present invention. In this embodiment, the self-moving device is an intelligent lawnmower 100 used for trimming garden lawns. It should be noted that in other embodiments, the self-moving device can also be a cleaning robot, a service robot, or other mobile robots that can walk autonomously and perform operations.

[0040] The intelligent lawnmower 100 includes a housing 1, a walking module 2 for supporting the movement of the housing 1, a cutting module 3 disposed at the bottom of the housing 1, a control device (not shown) at least partially installed in the housing 1 for controlling the automatic operation of the walking module 2 and controlling the automatic operation of the cutting module 3, and an energy component 4 for powering the intelligent lawnmower 100.

[0041] The housing 1 includes a base 11, a top cover 12 sealed to the base 11 to form a first chamber 14, and a cover 13 connected to the base 11 and / or the top cover 12 and defining a third chamber 15. Specifically, the base 11 is used to install functional modules such as the walking module 2, the cutting module 3, and the energy component 4; while the top cover 12 is configured to at least partially cover the base 11 and is sealed to the base 11 to form the first chamber 14, which is sealed and isolated from the external environment, and at least part of the control device is housed in the first chamber 14; the cover 13 is connected to the top cover 12 and defines the third chamber 15, and modules for user operation, such as the human-machine interface of the intelligent lawnmower 100, are disposed in the third chamber 15. It should be noted that the cover 13 being connected to the top cover 12 and defining the third chamber 15 is only one optional embodiment of this utility model. In other embodiments, the cover 13 may also be connected to the base 11, or simultaneously connected to both the base 11 and the top cover 12.

[0042] The walking module 2 is used to drive the intelligent lawnmower 100 to move within the working area, and includes drive wheels 21 and auxiliary wheels 22 mounted on the housing 1. Specifically, there are two drive wheels 21, each connected to a corresponding walking motor (not shown). The walking motor drives the drive wheels 21 to rotate, thereby enabling the intelligent lawnmower 100 to move automatically. The auxiliary wheels 22 mainly serve as auxiliary supports. There are one or two auxiliary wheels 22, located at the front of the intelligent lawnmower 100. The auxiliary wheels 22 are not connected to the walking motor, but they are driven to roll while supporting the intelligent lawnmower 100 to move. With the above structural arrangement, the intelligent lawnmower 100 can be controlled by a control device to move and turn flexibly on the working surface. During normal walking, the two walking motors output the same speed, directly driving or indirectly driving the intelligent lawnmower 100 through a transmission structure such as gears or belts, while the auxiliary wheel 22 also rolls. When turning, the two walking motors output different speeds, and the intelligent lawnmower 100 will turn towards the side of the driving wheel 21 with the lower speed or towards the side of the driving wheel 21 with the direction of reversing.

[0043] The cutting module 3 includes at least a cutting element 31 for cutting turf and a cutting motor 32 for driving the cutting element. Specifically, the cutting motor 32 is mounted on the base 11 of the housing 1. The cutting motor 32 is electrically connected to a control device, which can control the start and stop of the cutting motor 32 and adjust its speed. The cutting motor 32 is housed in a motor cylinder 33. A four-bar linkage (not shown) is provided between the motor cylinder 33 and the base 11, and the four-bar linkage rotatably connects the motor cylinder 33 and the base 11. Thus, when the intelligent lawnmower 100 encounters obstacles such as stones or low shrubs during its movement, the cutting element 31 will not collide directly with the obstacles, but will be pushed by the obstacles and drive the motor cylinder 33 to move in the vertical direction. This avoids damage to the cutting element 31 from direct collision with obstacles and improves the obstacle-crossing ability of the intelligent lawnmower 100. It should be noted that the cutting element 31 can be a cutting disc and multiple cutting blades mounted on the cutting disc, or it can be a single cutting blade; there is no limitation here.

[0044] The intelligent lawnmower 100 also includes an electrode holder 5 that interfaces with a charging device (not shown) to charge the energy component 4. Specifically, the electrode holder 5 includes a base 51 and an electrode plate 52 disposed on the base 51. The base 51 is connected to the housing 1. The electrode plate 52 includes a first docking end 521 for electrical connection with the charging device and a second docking end 522 for electrical connection with the energy component 4. The first docking end 521 and the second docking end 522 are respectively disposed at both ends in the longitudinal direction of the electrode plate 52. The first docking end 521 contacts the electrode plate at the corresponding position of the charging device to achieve electrical connection, while the second docking end 522 is connected to the energy component 4 through a wire to achieve electrical connection.

[0045] The intelligent lawnmower 100 also includes a bumper 6 movably connected to the housing. When the intelligent lawnmower 100 encounters obstacles in front of or to the side, the bumper 6 will prioritize contact with the obstacles. Specifically, the bumper 6 is U-shaped, located at the front of the intelligent lawnmower 100, and movably connected to the top cover 12 and / or the base 11. During the forward operation of the intelligent lawnmower 100, when it encounters an obstacle on the front side, the bumper 6 will prioritize contact with the obstacle and move relative to the housing 1 to buffer the impact, thereby reducing the impact force transmitted to the housing 1 and preventing damage to the internal components of the housing 1 from the impact.

[0046] The electrode base 5 also includes a stop block 53 disposed on the base body 51. In the front-rear direction of the intelligent lawnmower 100, the stop block 53 is at least partially located behind the impact plate 6 to prevent the impact plate 6 from continuing to move backward. Specifically, in a projection plane perpendicular to the front-rear direction of the intelligent lawnmower 100, the orthographic projection of the stop block 53 in the projection plane at least partially coincides with the orthographic projection of the impact plate 6 in the projection plane. Thus, on the one hand, by setting the stop block 53 behind the impact plate 6 to prevent the impact plate 6 from moving too much after contacting the obstacle, the elastic connection structure between the impact plate 6 and the housing 1 is prevented from being damaged by excessive compression and tension, thereby extending the service life of the elastic connection structure; on the other hand, since the stop block 53 is disposed on the electrode base 5, the housing 1 of the intelligent lawnmower 100 does not need to provide additional space for installing the stop block 53, thereby making the structure of the intelligent lawnmower 100 compact and facilitating the installation and arrangement of other components of the intelligent lawnmower 100.

[0047] In an optional embodiment of this utility model, the electrode 52 and the stop block 53 are both integrally formed on the base 51. Thus, the electrode base 5 is constructed as an independent part that can be detachably connected to the housing 1, which simplifies the assembly of the intelligent lawnmower 100 and facilitates disassembly and replacement.

[0048] Furthermore, the stop block 53 is at least partially located on the movement path of the impact plate 6 in the front-rear direction of the intelligent lawnmower 100, and at least partially located on the movement path of the impact plate 6 in the left-right direction of the intelligent lawnmower 100. Thus, the stop block 53 not only prevents the impact plate 6 from moving excessively backward after contacting the obstacle, but also further prevents excessive left-right movement of the impact plate 6. This further avoids damage to the elastic connection structure between the impact plate 6 and the housing 1 due to excessive compression and tension, extending the service life of the elastic connection structure. On the other hand, the intelligent lawnmower 100 does not require an additional structure to cooperate with the impact plate 6 to limit its left-right movement range, further simplifying the structure of the intelligent lawnmower 100.

[0049] The seat 51 includes a connecting portion 54 that is sealed to the housing 1 and defines a second chamber 16, which communicates with the first chamber 14. A first mating end 521 and a stop block 53 are disposed outside the first chamber 14 and the second chamber 16, and a second mating end 522 is disposed in the connecting portion 54 and located inside the first chamber 14 and / or the second chamber 16. Specifically, a first sealing element (not shown) is provided at the connection between the base 11 and the top cover 12, and a second sealing element (not shown) is provided at the connection between the connecting part 54 and the base 11 and / or the top cover 12. In this way, the fluid-connected first chamber 14 and second chamber 16 are isolated from the external environment. On the one hand, the second mating end 522 of the electrode 52 used to connect with the energy component 4 is located inside the first chamber 14 and / or the second chamber 16, isolated from the external environment, and has a good waterproof effect. On the other hand, the first mating end 521 of the electrode 52 used to connect with the charging device and the stop block 53 used to cooperate with the impact plate 6 to limit the movement range of the impact plate 6 are both located outside the first chamber 14 and the second chamber 16, and will not affect the sealing of the first chamber 14 and the second chamber 16, thus having a good sealing effect.

[0050] Furthermore, the base 51 also includes a support 55 connected to the connecting part 54. The first docking end 521 and the stop block 53 are both disposed on the support 55. In the height direction of the intelligent lawnmower 100, the first docking end 521 is disposed above the stop block 53. Specifically, the support part 55 includes an upper surface and a lower surface correspondingly disposed in the height direction of the intelligent lawnmower 100. The first docking end 521 is disposed on the upper surface of the support part 55, and the corresponding stop block 53 is disposed on the lower surface of the support part 55. In this way, on the one hand, the electrode 52 and the stop block 53 are respectively disposed on the upper and lower surfaces of the support part 55, making full use of the space in the height direction of the intelligent lawnmower 100, and avoiding the installation of the stop block 53 from occupying additional space in the front and rear directions of the intelligent lawnmower 100 and affecting the assembly of the cutting module and the control module; on the other hand, the smaller electrode 52 is disposed on the upper surface of the support part 55, while the larger stop block 53 is disposed on the lower surface of the support part 55, so that the load borne by the seat 51 used to support the electrode 52 and the stop block 53 is smaller, thereby reducing the strength requirement of the seat 51, reducing costs and making the structure more stable.

[0051] This utility model is not limited to the specific embodiments described above.
