Description

Technical Field

[0001] This application relates to the field of lawn mowing equipment, and in particular to an intelligent lawn mower and a docking charging system. Background Technology

[0002] With the continuous advancement of computer and artificial intelligence technologies, intelligent lawnmowers have been developed and launched on the market. These intelligent lawnmowers integrate environmental sensors, a self-driving system, a cutting system, a battery, and a charging system. They can mow lawns autonomously without manual operation, automatically returning to a charging station when the battery is low, docking and recharging, and then continuing to mow. Because this automated system requires no further management after being set up once, it frees users from the tedious and time-consuming task of lawn maintenance, and has therefore been widely adopted.

[0003] Existing smart lawnmowers typically have a charging slot at the front, with charging terminals located within it. During charging, the charging terminals are placed against the power terminals of the charging station, a simple connection method. However, the charging terminals in the charging slot are highly susceptible to moisture from rain or other liquids, leading to corrosion, poor contact, or even short circuits and burnout. Furthermore, during mowing, grass clippings, dust, and other debris can easily enter the charging slot, making it difficult to clean and also affecting charging functionality. Utility Model Content

[0004] To address the aforementioned problems, this application provides an intelligent lawnmower and its docking charging system. The system is ingeniously designed and has a simple structure. The charging terminals in this application are not easily wetted by rain or covered by grass clippings or other debris. The technical solution adopted in this application is as follows:

[0005] A smart lawnmower includes:

[0006] The system includes: a housing; several wheels disposed at the bottom of the housing; a cutting blade for cutting operations; a cutting motor for driving the cutting blade; a power supply module disposed within the housing for supplying power to the cutting motor; a charging slot recessed into the housing on the housing; a charging terminal for transmitting energy disposed within the charging slot in the power supply module; a baffle plate blocking the charging slot; when the charging terminal is in an initial state not connected to an external power terminal, the baffle plate blocks the opening of the charging slot; when the charging terminal is in a connected state connected to an external power terminal, the baffle plate and the charging terminal abut against two opposite sides of the external power terminal; the side of the baffle plate that abuts against the external power terminal is a smooth curved surface.

[0007] By installing a shield, the charging slot is protected from rainwater, grass clippings, dust, and other debris, preventing blockages, poor contact at the charging terminals, and even short circuits. Furthermore, in the docking state, the shield and the charging terminal face each other against the opposite sides of the external power terminal. This clamps the power terminal between the shield and the charging terminal, increasing the contact force, reducing conduction resistance, and ensuring reliable contact. Additionally, the side of the shield that abuts against the external power terminal is a smooth curved surface, allowing the charging tongue to move smoothly in and out of the charging slot, preventing jamming between the shield and the charging tongue, and ensuring more even pressure from the shield against the charging tongue, thus guaranteeing good contact between the power terminal and the charging terminal. It's easily overlooked that when the charging tongue is rotatable and self-resetting, the angle of the charging tongue (relative to the main body in the base) changes when there is a height difference between the charging tongue and the charging slot. Compared to the normal charging state, the contact point between the shield and the charging tongue changes, but it remains within the smooth curved surface area. The smooth curved surface design ensures a relatively stable distance between the contact point and the charging terminal, thereby ensuring stable clamping force between the shield and the charging terminal and increasing contact reliability.

[0008] In some embodiments, the shield is rotatably connected to the charging slot via a first elastic member; in the initial state, under the action of the first elastic member, the free end of the shield abuts against the opening of the charging slot from the inside; in the docking state, under the action of the first elastic member, the side of the shield with a smooth curved surface abuts against the external power terminal.

[0009] By incorporating a first elastic element, the self-resetting function of the baffle is ensured. This ensures that the baffle is always subjected to the restoring deformation force of the first elastic element during rotation. In the initial state, the baffle will not be accidentally opened. In the docking state, the restoring deformation force of the first elastic element increases the abutment force of the baffle against the charging tongue, thereby ensuring good contact between the power terminal and the charging terminal on the charging tongue. It is important to note that the elastic force of the first elastic element is preset to be very small to avoid excessive resistance when the charging tongue enters the charging slot. Furthermore, after the charging tongue pushes against the baffle and the baffle rotates to its limit position, the back of the baffle (the side away from the charging terminal) abuts against the inner wall of the charging slot, further enhancing the clamping effect of the baffle and the charging terminal on the charging tongue.

[0010] In some embodiments, the first elastic element is a first torsion spring, the shield plate is provided with a first pivot portion, the first torsion spring is sleeved on the first pivot portion, one leg of the first torsion spring abuts against the shield plate, and the other leg of the first torsion spring abuts against the inner wall of the charging slot.

[0011] In some embodiments, the charging slot extends longitudinally into the housing, the charging terminal is located on the lower wall of the charging slot, and as the baffle rotates from the initial state to the docking state, the free end of the baffle gradually approaches the upper wall of the charging slot.

[0012] By placing the charging terminals on the lower wall of the charging slot, and as the baffle plate rotates from the initial state to the docking state, the free end of the baffle plate gradually approaches the upper wall of the charging slot. In other words, as the baffle plate rotates from the initial state to the docking state, it gradually rotates upward. Thus, even without the first elastic element, the baffle plate will block the charging slot under the action of gravity in the initial state.

[0013] On the other hand, this application also provides a docking charging system, including a charging station and the aforementioned smart lawnmower. The charging station includes: a base; and a power terminal. The power terminal is disposed on the base. When the charging station transfers energy to the smart lawnmower, the power terminal extends into the charging slot of the smart lawnmower and docks with the charging terminal.

[0014] In some embodiments, the base includes a main body and a charging tongue connected to the main body, with the power terminal disposed at the end of the charging tongue. When the charging station transfers energy to the smart lawnmower, the charging tongue extends into the charging slot of the smart lawnmower.

[0015] In some embodiments, the charging tongue is rotatably connected to the body in a self-resetting manner.

[0016] The charging tongue is rotatably connected to the main body and can self-reset. When there is a height difference between the charging tongue and the charging slot in the initial position, the charging tongue can adaptively rotate downwards or upwards by abutting against the baffle plate or the edge of the charging slot opening, thus entering the charging slot. This self-resetting rotatable connection improves the charging tongue's adaptability to height differences between it and the charging slot. Furthermore, it increases the contact force between the power terminals and the charging terminals, ensuring good contact between them.

[0017] In some embodiments, the charging tongue is provided with a second pivot portion, the charging tongue is rotatably connected to the main body through the second pivot portion, the second pivot portion is provided with a slot, the second pivot portion is fitted with a second torsion spring, one leg of the second torsion spring is engaged in the slot, and the other leg of the second torsion spring abuts against the main body.

[0018] In some implementations, the power terminal and the charging terminal are elastically connected when docked.

[0019] The flexible connection between the power terminal and the charging terminal reduces the positional accuracy requirements of the power terminal and the charging terminal, reduces the difficulty of docking the power terminal and the charging terminal, and ensures that there is sufficient contact force between the power terminal and the charging terminal, thereby ensuring good contact between the power terminal and the charging terminal.

[0020] In some embodiments, the charging station further includes a base plate, on which the base is located, and the entire intelligent lawnmower is situated on the base plate when the charging station transfers energy to the intelligent lawnmower.

[0021] The intelligent lawnmower and docking charging system provided in this application have at least one of the following beneficial effects:

[0022] 1. This application provides an intelligent lawnmower that, by setting up a baffle plate, prevents rainwater, grass clippings, dust, and other debris from entering the charging slot, thus avoiding blockages, poor contact of the charging terminals, and even short circuits. Furthermore, in the docking state, the baffle plate and the charging terminals face each other against the two opposite sides of the external power terminal. This clamps the power terminal between the baffle plate and the charging terminal, increasing the contact force, reducing conduction resistance, and ensuring reliable contact between the power terminal and the charging terminal. In addition, the side of the baffle plate that abuts against the external power terminal is a smooth curved surface, allowing the charging tongue to move in and out of the charging slot more smoothly, preventing jamming between the baffle plate and the charging tongue, and ensuring more even pressure from the baffle plate against the charging tongue, thus ensuring good contact between the power terminal and the charging terminal. It is easily overlooked that, in the rotatable and self-resetting state of the charging tongue, when there is a height difference between the charging tongue and the charging slot, the angle of the charging tongue (relative to the main body in the base) changes. Compared to the normal charging state, the contact point between the shield and the charging tongue changes, but it remains within the smooth curved surface area. The smooth curved surface design ensures a relatively stable distance between the contact point and the charging terminal, thereby ensuring stable clamping force between the shield and the charging terminal and increasing contact reliability.

[0023] 2. The intelligent lawnmower provided in this application ensures the self-resetting function of the cover plate by setting a first elastic element. This ensures that the cover plate is always subjected to the restoring deformation force of the first elastic element when rotating. In the initial state, the cover plate will not be accidentally opened. In the docking state, due to the existence of the restoring deformation force of the first elastic element, the contact force between the cover plate and the charging tongue can be increased, thereby ensuring good contact between the power terminal and the charging terminal on the charging tongue. It should be noted that the elastic force of the first elastic element is preset to be very small to avoid excessive resistance when the charging tongue enters the charging slot. In addition, after the charging tongue pushes against the cover plate and the cover plate rotates to its limit position, the back of the cover plate (the side away from the charging terminal) abuts against the inner wall of the charging slot, further enhancing the clamping of the charging tongue by the cover plate and the charging terminal.

[0024] 3. The intelligent lawnmower provided in this application sets the charging terminal on the lower wall of the charging slot. During the process of the baffle plate rotating from the initial state to the docking state, the free end of the baffle plate gradually approaches the upper wall of the charging slot. That is to say, during the process of the baffle plate rotating from the initial state to the docking state, the baffle plate gradually rotates upward. Thus, even without the first elastic element, the baffle plate will block the charging slot under the action of gravity in the initial state.

[0025] 4. This application provides a docking charging system in which the charging tongue is rotatably connected to the main body and can self-reset. When a height difference exists between the charging tongue and the charging slot in the initial position, the charging tongue can adaptively rotate downwards or upwards by abutting against a baffle plate or against the edge of the charging slot opening, thus entering the charging slot. The self-resetting rotatable connection of the charging tongue to the main body improves its adaptability to height differences between the charging tongue and the charging slot. Furthermore, it increases the contact force between the power terminal and the charging terminal, thereby ensuring good contact between the power terminal and the charging terminal.

[0026] 5. The docking charging system provided in this application reduces the positional accuracy requirements of the power terminal and the charging terminal by elastically connecting the power terminal and the charging terminal, reduces the docking difficulty of the power terminal and the charging terminal, and at the same time ensures that there is sufficient contact force between the power terminal and the charging terminal, thereby ensuring good contact between the power terminal and the charging terminal.

[0042] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] refer to Figures 1-8 As shown, a docking charging system includes a smart lawnmower and a charging station. The smart lawnmower performs mowing operations, and the charging station is used to charge the returning smart lawnmower.

[0044] In this embodiment, the intelligent lawnmower includes a housing 19 extending longitudinally, several wheels disposed at the bottom of the housing 19, and a drive motor disposed within the housing 19. The drive motor drives the wheels to rotate, thereby enabling the intelligent lawnmower to move. The housing 19 also includes a power supply module, a cutting blade for cutting operations, and a cutting motor for driving the cutting blade. The power supply module supplies power to the drive motor and the cutting motor.

[0045] The power supply module includes a charging terminal 2, which is used to contact and electrically connect with an external power terminal 8 to charge the smart lawnmower. A charging groove 1 is provided at the front center between the top and bottom of the housing 19, which extends longitudinally into the housing 19. The charging terminal 2 is disposed in the charging groove 1.

[0046] Please refer to Figures 1-6 , Figure 8 The charging station includes a base and a base plate 12 disposed beneath the base. The base includes a main body 9 and a charging tongue 7 connected to the main body 9. (Reference) Figure 1 , Figure 6 When the charging tongue 7 is not connected to the charging slot 1, it is roughly horizontal. Its height relative to the base plate 12 is basically the same as the height of the charging slot 1 of the smart lawnmower. In other words, the heights of the two are roughly the same.

[0047] refer to Figure 1-Figure 5 The charging tongue 7 has a power terminal 8 at its end. When the charging station charges the smart lawnmower, the end of the charging tongue 7 extends into the charging slot 1 of the smart lawnmower, and the power terminal 8 is electrically connected to the charging terminal 2.

[0048] The base is located on the bottom plate 12. When the charging station charges the smart lawnmower, the entire smart lawnmower is located on the bottom plate 12 to ensure the uniformity of the smart lawnmower's height.

[0049] refer to Figure 1-Figure 5 , Figure 7 The intelligent lawnmower also includes a cover plate 3 that blocks the charging slot 1. The cover plate 3 is rotatably connected to the charging slot 1. When the charging terminal 2 is in the initial state of not being connected to the external power terminal 8, the cover plate 3 blocks the opening of the charging slot 1. When the charging terminal 2 is in the connected state of being connected to the external power terminal 8, the cover plate 3 and the charging terminal 2 abut against the two opposite sides of the external power terminal 8. The side of the cover plate 3 that abuts against the external power terminal 8 is a smooth curved surface 4.

[0050] Understandably, by setting up the shield 3, the shielding of the charging slot 1 prevents rainwater, grass clippings, dust, and other debris from entering the charging slot 1, avoiding blockages and poor contact of the charging terminals 2, or even short circuits. Furthermore, in the docking state, the shield 3 and the charging terminals 2 abut against the opposite sides of the external power terminal 8, thus clamping the power terminal 8 between the shield 3 and the charging terminal 2, increasing the contact force, reducing conduction resistance, and ensuring reliable contact between the power terminal 8 and the charging terminal 2. In addition, the side of the shield 3 that abuts against the external power terminal 8 is a smooth curved surface 4, which makes the charging tongue 7 move more smoothly in and out of the charging slot 1, preventing jamming between the shield 3 and the charging tongue 7, and ensuring more even pressure from the shield 3 against the charging tongue 7, thus ensuring good contact between the power terminal 8 and the charging terminal 2. What is easily overlooked is that, in the rotatable and self-resetting state of the charging tongue 7, when a height difference exists between the charging tongue 7 and the charging slot 1, the angle of the charging tongue 7 (relative to the main body in the base) changes. Compared to the normal charging state, the contact point of the baffle 3 against the charging tongue 7 changes, but it is still within the area of ​​the smooth curved surface 4. The design of the smooth curved surface 4 makes the distance from the contact point to the charging terminal 2 relatively stable, thereby ensuring the stability of the clamping force between the baffle 3 and the charging terminal 2 and increasing the reliability of the contact.

[0051] refer to Figure 1-Figure 5 , Figure 7 In one embodiment, the shield 3 is rotatably connected to the charging slot 1 via a first elastic member; in the initial state, under the action of the first elastic member, the free end of the shield 3 abuts against the opening of the charging slot 1 from the inside; in the docking state, under the action of the first elastic member, the side of the shield 3 with the smooth curved surface 4 abuts against the external power terminal 8.

[0052] It is easy to understand that by setting the first elastic element, the self-resetting function of the baffle plate 3 is ensured. This ensures that the baffle plate 3 is always subjected to the restoring deformation force of the first elastic element when rotating. In the initial state, the baffle plate 3 will not be accidentally opened. In the docking state, due to the existence of the restoring deformation force of the first elastic element, the contact force between the baffle plate 3 and the charging tongue 7 is increased, thereby ensuring good contact between the power terminal 8 on the charging tongue 7 and the charging terminal 2. It should be noted that the elastic force of the first elastic element is preset to be very small to avoid excessive resistance when the charging tongue 7 enters the charging slot 1. In addition, after the charging tongue 7 pushes against the baffle plate 3 and the baffle plate 3 rotates to its limit position, the back of the baffle plate 3 (the side away from the charging terminal) abuts against the inner wall of the charging slot 1, further enhancing the clamping of the charging tongue 7 by the baffle plate 3 and the charging terminal 2. The first elastic element can be a spring sheet, torsion spring, etc., as long as it can reset the baffle plate 3.

[0053] refer to Figure 7 In one embodiment, the first elastic element is a first torsion spring 5, the shielding plate 3 is provided with a first pivot portion 6, the first torsion spring 5 is sleeved on the first pivot portion 6, one leg of the first torsion spring 5 abuts against the shielding plate 3, and the other leg of the first torsion spring 5 abuts against the inner wall of the charging tank 1.

[0054] Specifically, refer to Figure 7 The upper end of the baffle plate 3 has two rotating shaft portions 18 on both sides, and the charging slot 1 has a rotating shaft mounting groove 13. The rotating shaft portion 18 of the baffle plate 3 is installed in the rotating shaft mounting groove 13 of the charging slot 1 to achieve a rotatable connection between the baffle plate 3 and the charging slot 1. The charging slot 1 includes an upper cover 14 and a lower shell 15. The upper cover 14 and the lower shell 15 divide a complete rotating shaft mounting groove 13 into two parts, which facilitates the installation of the rotating shaft portion 18 into the rotating shaft mounting groove 13. For example, the rotating shaft portion 18 is first installed into part of the rotating shaft mounting groove 13 on the lower shell 15, and then the upper cover 14 is installed onto the lower shell 15, thus completing the rotatable connection between the baffle plate 3 and the charging slot 1.

[0055] In one embodiment, the charging terminal 2 is located on the lower wall of the charging slot 1. During the process of the baffle 3 rotating from the initial state to the docking state, the free end of the baffle 3 gradually approaches the upper wall of the charging slot 1. That is, the height of the rotating shaft of the baffle 3 is higher than the height of the free end of the baffle 3 in the initial state. During the process of the charging tongue 7 being inserted into the charging slot 1, the charging tongue 7 pushes the baffle 3 to gradually rotate upward. Thus, even without the first elastic element, in the initial state, the baffle 3 will automatically reset and block the charging slot 1 under the action of gravity.

[0056] refer to Figure 3-Figure 5In one embodiment, the charging tongue 7 is rotatably connected to the main body 9 in a self-resetting manner. Specifically, the self-resetting function of the charging tongue 7 after rotation can be achieved using a spring, torsion spring, or the like. It is worth noting that the charging tongue 7 is rotatably connected to the main body 9 in a self-resetting manner. Thus, when there is a height difference between the charging tongue 7 and the charging slot 1 in the initial position, the charging tongue 7 can adaptively rotate downwards or upwards by abutting against the baffle plate 3 or by abutting against the edge of the opening of the charging slot 1, thereby entering the charging slot 1. The self-resetting rotatable connection of the charging tongue 7 to the main body 9 improves the adaptability of the charging tongue 7 to height differences between the charging tongue 7 and the charging slot 1. Furthermore, it increases the contact force between the power terminal 8 and the charging terminal 2, thereby ensuring good contact between the power terminal 8 and the charging terminal 2.

[0057] Figure 1-Figure 3 The process of the charging tongue 7 gradually connecting with the charging slot 1 is demonstrated. Before contacting the baffle plate 3, the charging tongue 7 is essentially horizontal. After connection, the charging tongue 7 tilts slightly downwards under the pressure of the baffle plate 3, increasing the contact force between the power terminal 8 and the charging terminal 2 and reducing the conduction resistance. With increased use, the wheels of the smart lawnmower will wear down, causing the overall height of the lawnmower to decrease. This creates a height difference between the charging slot 1 and the charging tongue 7 before connection. However, the rotatable design of the charging tongue 7 allows it to adapt to this height difference, ensuring that the end of the charging tongue 7 enters the charging slot 1. The final connection state of the charging tongue 7 and the charging slot 1 is as follows. Figure 4 As shown. In Figure 4 In the middle, because the overall height of the smart lawnmower is reduced, the charging tongue 7 tilts downwards to a greater degree than... Figure 3 .

[0058] Understandably, sometimes when a smart lawnmower returns to its charging dock, its wheels may have dirt, grass clippings, or other debris stuck to them. This causes the overall height of the lawnmower to increase, creating a height difference between the charging slot 1 and the charging tongue 7 before they dock. The rotatable design of the charging tongue 7 solves this problem, resulting in the final docking state between the charging tongue 7 and the charging slot 1 as shown below. Figure 5 As shown. In Figure 5 In the middle, because the overall height of the smart lawnmower is increased, the charging tongue 7 tilts downwards to a lesser degree than... Figure 3 .

[0059] It should be noted that the self-resetting rotatable connection of the charging tongue 7 to the main body 9 also facilitates the transportation of the charging station. During transportation, multiple charging stations are stacked on top of each other, and the charging tongue 7 is no longer in a horizontal state, but rather in an angled upward or downward state, thus saving transportation space.

[0060] refer to Figure 8This paper describes a method for enabling the charging tongue 7 to be rotatably connected to the main body 9 in a self-resetting manner. The charging tongue 7 is provided with a second pivot part 10, and the charging tongue 7 is rotatably connected to the main body 9 through the second pivot part 10. The second pivot part 10 is provided with a slot 11, and a second torsion spring 20 is sleeved on the second pivot part 10. One leg of the second torsion spring 20 is engaged in the slot 11, and the other leg of the second torsion spring 20 abuts against the main body 9.

[0061] Specifically, the main body 9 has a perforation (not shown in the figure), and a U-shaped slot 16 is provided on the side of the main body 9 away from the intelligent lawnmower. The charging tongue 7 passes through the perforation, the second pivot part 10 is placed in the U-shaped slot 16, one leg of the second torsion spring 20 is locked in the slot 11, and the other leg of the second torsion spring 20 abuts against the groove wall of the U-shaped slot 16. A buckle cover 17 is installed at the opening of the U-shaped slot 16 to restrict the second pivot part 10 in the U-shaped slot 16.

[0062] refer to Figure 1-Figure 5 In one embodiment, during the docking state, the power terminal 8 and the charging terminal 2 are elastically connected. This elastic connection reduces the positional accuracy requirements of the power terminal 8 and the charging terminal 2, decreases the difficulty of docking, and ensures sufficient contact force between them, thus guaranteeing good contact. There are various ways to implement the elastic connection; for example, the power terminal 8 can be a spring contact, and the charging terminal 2 can be a fixed metal plate; or, the power terminal 8 can be a fixed metal plate, and the charging terminal 2 can be a spring contact; or both the power terminal 8 and the charging terminal 2 can be spring contactes.

[0063] In other embodiments, the power terminal 8 may also extend movably from the base. When the smart lawnmower is not docked with the charging station for charging, the power terminal 8 is hidden inside the base; when the smart lawnmower returns to the charging station, the charging station can sense the arrival of the smart lawnmower, thereby causing the power terminal 8 to extend from inside the base.

[0064] In this embodiment, the intelligent lawnmower and docking charging system feature a smooth curved surface 4 on the side of the shield 3 that abuts against the external power terminal 8. This allows the shield 3 to have a larger contact area when it comes into contact with the external power terminal 8, ensuring good contact between the power terminal 8 and the charging terminal 2, and preventing jamming between the shield 3 and the external power terminal 8. Simultaneously, the smooth curved surface 4 of the shield 3 also guides the power terminal 8 into the charging slot 1, accommodating situations where there is a height difference between the charging tongue 7 and the charging slot 1.

[0065] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
