Detailed Description
The following detailed description of embodiments of the invention is, therefore, to be taken in conjunction with the accompanying drawings, and it is to be understood that the scope of the invention is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations thereof such as "comprises" or "comprising", etc. will be understood to include the stated element or component without excluding other elements or components.
As for the prior art, most of the existing devices for charging intelligent self-propelled devices (such as mowers) can start charging by completely contacting their receiving ends with the elastic conductors on the charging base, and the elastic conductors on the charging base cannot be soaked with water, so that the existing intelligent self-propelled devices (such as mowers) are greatly limited by site conditions during charging, and meanwhile, the problem of poor charging efficiency caused by poor contact exists.
In order to solve the above problems, the present invention innovatively proposes a wireless charging system, in which a radio transmitting module and a radio receiving module are respectively disposed on a charging base and a self-propelled device, and the base is set to have a certain height so that the self-propelled device can be jacked up when the charging base and the self-propelled device are in butt joint, so that the radio transmitting module and the radio receiving module are fully in butt joint, the coupling and charging efficiency are greatly improved, the limitation of a charging field to charging is reduced, and the charging cost is also reduced.
The following describes in detail the embodiments of the present invention with reference to the drawings.
As shown in fig. 1 to 3, an embodiment of the present invention provides a wireless charging system, which includes a self-propelled device 10 and a wireless charging station 20 that can cooperate with the self-propelled device 10 to charge the self-propelled device 10.
The self-propelled apparatus 10 includes a housing 11, a walking assembly 12, a driving module, a sensing assembly, and a radio receiving module 13.
The traveling assembly 12 is provided on the housing 11 for movement of the self-propelled apparatus 10. The walking assembly 12 comprises a walking wheel set 121 positioned at the front end of the shell 11 and a driving wheel set 122 positioned at the rear end of the shell 11, and the walking wheel set 121 comprises two walking wheels which are symmetrically arranged and are separated by a certain interval; the drive wheel set 122 includes two symmetrically disposed drive wheels. The walking component 12 is movably arranged relative to the shell 11 in the vertical direction, so that the self-walking device 10 meets an obstacle with a certain height on the chassis or the self-walking device 10 is in a vacation state (in both states, the walking component 12 is in a state of being far away from the shell 11), and a lifting protection mechanism is triggered, for example, a cutting blade of a mower stops cutting or a roller of a sweeper stops running, and the like.
The driving module is disposed in the housing 11 and connected to the traveling assembly 12, and can at least drive the driving wheel set 122 of the traveling assembly 12 to operate, so that the self-propelled apparatus 10 can continuously provide driving force when the self-propelled apparatus is ready to charge (the traveling wheel set 121 is lifted). Of course, the driving module can also drive the traveling wheel set 121 and the driving wheel set 122 to operate together. The traveling and the direction change of the self-propelled apparatus 10 are completed by the driving module and the traveling module.
The sensing component is arranged on the walking component 12 and/or the shell 11, and is used for sensing the relative position relationship between the walking component 12 and the shell 11 and generating corresponding sensing signals.
The radio receiving module 13 is disposed at the bottom of the front end of the housing 11 of the self-walking device 10 in the moving direction, and the radio receiving module 13 has a second docking surface disposed horizontally with respect to the bottom of the self-walking device 10, and the second docking surface can cooperate with the surface of the corresponding radio transmitting module to wirelessly charge the self-walking device 10.

The control module is connected with the driving module, the sensing assembly and the electric quantity detection module, and can control the driving module to provide or cut off driving force for the walking assembly according to the sensing signal generated by the sensing assembly. The electric quantity detection module is used for detecting the electric quantity of the battery pack.
The self-propelled apparatus 10 has a lift protection mechanism. Specifically, the sensing component is arranged on the walking wheel set 121 or the shell 11, when the self-walking equipment 10 moves and operates, the walking wheel set 121 and the shell 11 form a first position relation, the sensing component forms a first sensing signal in the state, and the control module controls the driving module to provide driving force for the walking component 12 according to the first sensing signal; when part or all of the walking wheel set 121 leaves the ground, the walking wheel set 121 forms a second position relation with the shell 11 under the self gravity, the sensing assembly forms a second sensing signal in the state, and the control module controls the driving module to cut off the driving force supply to the walking assembly 12 according to the second sensing signal. However, when the electric quantity detection module detects that the electric quantity of the battery pack of the self-propelled device 10 is less than or equal to the preset electric quantity, the control module cuts off the connection with the induction component and controls the driving module to continuously provide driving force for the walking component 12 until the radio receiving module at the bottom of the self-propelled device 10 is in alignment contact with the corresponding radio transmitting module.
In this embodiment, the self-propelled apparatus 10 may be a mower, and may further include a cutting assembly and other components of the mower that can automatically cut grass, such as a cutting blade that is driven to rotate to cut grass, and the components are connected to the control module.
In other embodiments, the self-propelled apparatus 10 may also be a sweeper or scrubber.
The wireless charging station 20 includes a base 21 and a radio transmission module 22. The radio transmission module 22 is provided on the base 21. The width of the base 21 in the moving direction of the self-propelled apparatus 10 is equal to or less than (preferably less than) the distance between the two traveling wheels of the self-propelled apparatus 10; the base 21 has a height which is only required to be larger than the height of the radio receiving module from the ground when the self-propelled device 10 moves and operates, and when the radio receiving module is aligned with the radio transmitting module, the walking component 12 on the upper part of the self-propelled device 10 is suspended relative to the ground under the action of the base 21.
In one embodiment, the base 21 has a guide surface 211 and a contact surface 212 connected to the guide surface 211, the guide surface 211 is inclined with respect to the moving direction of the self-propelled apparatus 10, the guide surface 211 is inclined at an angle of 5-35 ° with respect to the ground, and preferably the guide surface 211 is inclined at an angle of 10 ° with respect to the ground. The contact surface 212 extends horizontally from the top end of the guiding surface 211 along the moving direction of the self-propelled device 10, and the radio transmitting module 22 is disposed on the contact surface 212.
The radio transmitting module 22 has a first docking surface horizontally disposed with respect to the contact surface 212 of the base 21, and when the radio receiving module 13 of the self-propelled device 10 is aligned with the radio transmitting module 22 on the base 21, the first docking surface is opposite to the second docking surface to wirelessly charge the self-propelled device 10. When the radio receiving module is in alignment contact with the radio transmitting module, the distance between the first abutting surface and the second abutting surface is between 0 and 20 mm.
Referring to fig. 4 and 5, fig. 4 and 5 are a side view and a top view, respectively, of a wireless charging system in a charged state. When the electric quantity detection module of the self-propelled device 10 detects that the electric quantity of the internal battery pack is lower than the preset electric quantity, the control module controls the driving module to drive the traveling assembly to operate, and the self-propelled device 10 automatically searches for the wireless charging station 20 (provided with a navigation module capable of automatically navigating). At this time, the control module simultaneously cuts off the connection with the sensing assembly and controls the driving module to continuously provide driving force to the walking assembly 12. After the wireless charging station 20 is found, the base 21 is arranged between the traveling wheel groups of the self-traveling equipment 10 in a penetrating manner, after the radio receiving module at the bottom of the self-traveling equipment 10 is in contact with the base 21, the self-traveling equipment 10 climbs upwards along the guide surface 211 of the base 21 under the acting force of the traveling component 12 and the supporting force of the base 10, the front end of the self-traveling equipment 10 is jacked up, at the moment, the control module cuts off the connection with the sensing component, so that the lifting protection mechanism of the self-traveling equipment 10 fails, and the driving module continues to provide driving force for the traveling component 12 until the radio receiving module at the bottom is sufficiently close to the radio transmitting module on the base 21 and starts to be in counterpoint contact, the driving module cuts off the driving force supply, and the self-traveling equipment 10 starts to charge.
The invention also provides a control disabling method for the power failure caused by the lifting of the self-propelled equipment, which comprises the following steps: acquiring the electric quantity of the battery pack detected by the electric quantity detection module; judging whether the electric quantity is smaller than or equal to a preset electric quantity or not; and if the electric quantity is smaller than or equal to the preset electric quantity, controlling the control module to cut off the connection with the induction component.
Compared with the prior art, the wireless charging system of the embodiment of the invention has the advantages that the base with a certain height is arranged, and the wireless transmitting module is arranged on the surface of the base, so that the self-propelled equipment can be partially jacked up when the base is contacted with the wireless receiving module on the self-propelled equipment, the opposite contact of the wireless transmitting module and the wireless receiving module is ensured, and the coupling and charging efficiency is improved.
