Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Please see the appendix Figure 1A lawnmower charging device includes a lawnmower body 1, a lawnmower charging connector 10, a charging base charging plate 11, a charging box 13, a left control component, a right control component, and a charging base base plate 19. The charging box 13 is rotatably embedded in the middle of the charging base base plate 19 and connected to an external power source. The left end of the charging box 13 is movably connected to the charging base base plate 19 via the left control component, and the right end of the charging box 13 is movably connected to the charging base base plate 19 via the right control component. A pair of lawnmower charging connectors 10 are installed... At the bottom of the lawnmower body 1, a pair of charging pads 11 are mounted on the top of the charging box 13. When the lawnmower body 1 moves onto the charging pad base 19, the wheels on both sides of the lawnmower body 1 can press down on the left and right control components respectively, and the pair of charging pads 11 can connect with a pair of lawnmower charging connection pieces 10. When the lawnmower body 1 moves away from the left and right control components, the charging box 13 can be locked in the mounting hole in the middle of the charging pad base 19 through the left and right control components.

[0023] The lawnmower body 1 can be a rechargeable lawnmower device using existing technology, and the charging box 13 uses a charging component compatible with the rechargeable lawnmower device. A pair of lawnmower charging connectors 10 of the lawnmower body 1 are installed at the bottom of the lawnmower body 1, and the charging box 13 with a pair of charging base plates 11 on the top is embedded in the mounting hole in the middle of the charging base plate 19. This allows the pair of charging base plates 11 to engage with the pair of lawnmower charging connectors 10 to achieve charging when the lawnmower body 1 travels onto the charging base plate 19. This solves the problem in the prior art where the pair of charging base plates 11 are positioned in the forward direction of the lawnmower body 1, which makes the pair of charging base plates 11 easily damaged by collisions.

[0024] When not charging, the charging box 13 is locked in the mounting hole in the middle of the charging base plate 19 by the left and right control components, which can effectively prevent the charging box 13 from being exposed and damaged. When charging, the lawnmower body 1 moves onto the charging base plate 19 and triggers the left and right control components, causing the charging box 13 to rotate and pop out from the mounting hole in the middle of the charging base plate 19, so that a pair of charging base charging plates 11 align with a pair of lawnmower charging connection plates 10 to achieve charging.

[0025] The left end of one side of the charging box 13 is rotatably connected to the charging base plate 19 via a rotating shaft and a left reset torsion spring 02. The right end of one side of the charging box 13 is rotatably connected to the charging base plate 19 via a rotating shaft and a right reset torsion spring 12. The left end of the other side of the charging box 13 is movably connected to the left control component, and the right end of the other side of the charging box 13 is movably connected to the right control component.

[0026] When not charging, the left and right ends of one side of the charging box 13 are constrained within the mounting holes in the middle of the charging base plate 19 by a pivot. The left and right ends of the other side of the charging box 13 are respectively constrained within the mounting holes in the middle of the charging base plate 19 by a left control component and a right control component, ensuring that the charging box 13 is embedded inside the charging base plate 19 and not exposed, thus preventing damage to the pair of charging pads 11 due to protrusion. At this time, the left reset torsion spring 02 and the right reset torsion spring 12 of the charging box torsionally store force.

[0027] During charging, the left and right control components release the restrictions on the left and right ends of the other side of the charging box 13. Under the elastic force of the left reset torsion spring 02 and the right reset torsion spring 12 of the charging box, the charging box 13 rotates upward around the rotation axis of the left and right ends of one side to exit the mounting hole of the charging base plate 19. This causes a pair of charging base charging plates 11 on the charging box 13 to move upward and connect precisely with a pair of lawnmower charging connection plates 10 at the bottom of the lawnmower body 1, thus realizing the charging action.

[0028] The left control component includes a left bottom cover 18, a left drive shaft 16, and a left eject button 14. The left bottom cover 18 is embedded in the charging base plate 19 and is located below the left wheel of the lawnmower body 1 at its resting position. A left mounting hole is formed on the left bottom cover 18 and the charging base plate 19. The left eject button 14 can be spring-loaded into the left mounting hole so that when the lawnmower body 1 moves onto the charging base plate 19, the left wheel of the lawnmower body 1 can press down the left eject button 14. One end of the left drive shaft 16 is rotatably inserted into the left bottom cover 18, and the other end of the left drive shaft 16 is movably connected to the left end of the charging box 13.

[0029] When not charging, the left pop-out button 14 pops out above the surface of the charging base plate 19. When charging, when the lawnmower body 1 moves onto the charging base plate 19, it presses down on the left pop-out button 14. When the left pop-out button 14 is pressed down, it pushes the left drive shaft 16 to rotate counterclockwise and releases the lock on the other left end of the charging box 13.

[0030] After charging is complete, the lawnmower body 1 moves away from the charging base plate 19, releases the pressure on the left pop-out button 14, the left pop-out button 14 rotates clockwise to reset, and locks the other left end of the charging box 13 to the charging base plate 19.

[0031] The other end of the left drive shaft 16 is provided with a locking hook 20, and the left end of the charging box 13 is provided with a locking hook groove (not shown in the figure) that matches the locking hook 20. When the left drive shaft 16 rotates, the locking hook 20 can rotate and embed into the locking hook groove, locking the left end of the charging box 13 onto the charging base plate 19, or the locking hook 20 can rotate out of the locking hook groove and release the locking of the left end of the charging box 13.

[0032] One end of the locking hook 20 is fixed to the left drive shaft 16, and the locking hook 20 rotates synchronously with the left drive shaft 16. The rotation trajectory of its other end is circular. Preferably, the locking hook groove can be an arc-shaped groove. During the clockwise and counterclockwise rotation of the left drive shaft 16, the other end of the locking hook 20 can slide between the two ends of the locking hook groove. One end of the locking hook groove is the locking end, and the other end is the unlocking end that penetrates the charging box 13. A locking tongue can be provided at the other end of the locking hook 20, and a locking hole is provided in the locking end of the locking hook groove. The locking hook 20 locks the charging box 13 by matching and engaging the locking tongue and the locking hole.

[0033] Using a matching latch and lock hole structure to lock and unlock rotating parts is a common technique in this field. The appropriate type of latch and lock hole structure can be selected according to actual usage requirements. The specific structure and locking and unlocking process will not be described in detail here.

[0034] The left drive shaft 16 is provided with a pressure plate 21, and the left pop-out button 14 is spring-loaded on the pressure plate 21 via a left spring 15.

[0035] The pressure plate 21 is fixed to the left drive shaft 16. When the left pop-out button 14 is pressed down, the left spring 15 is compressed and stores force, which is then transmitted to the pressure plate 21, pushing the pressure plate 21 downward. Preferably, a through hole is provided on the left bottom cover 18 for the left drive shaft 16 to pass through, allowing the left drive shaft 16 to rotate clockwise or counterclockwise within the through hole. This restricts the movement mode and trajectory of the left drive shaft 16, so that when the pressure plate 21 is pressed down, it can drive the left drive shaft 16 to rotate counterclockwise, and when the pressure plate 21 is released, the left drive shaft 16 rotates clockwise.

[0036] A left reset torsion spring 17 is sleeved on the left drive shaft 16, and the two ends of the left reset torsion spring 17 are fixedly connected to the left drive shaft 16 and the left bottom cover 18, respectively.

[0037] By coaxially connecting the left reset torsion spring 17 to the left drive shaft 16, when the left drive shaft 16 rotates counterclockwise relative to the left bottom cover 18, the left reset torsion spring 17 torsionally stores force, which facilitates the use of the elastic force of the left reset torsion spring 17 to drive the left drive shaft 16 to rotate clockwise, thereby achieving automatic reset.

[0038] The right control component includes a right bottom cover 07, a right drive shaft 05, and a right pop-out button 03. The right bottom cover 07 is embedded in the charging base plate 19 and is located below the right wheel of the lawnmower body 1 at its resting position. A right mounting hole is formed on the right bottom cover 07 and the charging base plate 19. The right pop-out button 03 can be spring-loaded into the right mounting hole so that when the lawnmower body 1 moves onto the charging base plate 19, the right wheel of the lawnmower body 1 can press down the right pop-out button 03. One end of the right drive shaft 05 is rotatably inserted into the right bottom cover 07, and the other end of the right drive shaft 05 is movably connected to the right end of the charging box 13.

[0039] When not charging, the right pop-out button 03 pops out above the surface of the charging base plate 19. When charging, when the lawnmower body 1 moves onto the charging base plate 19, it presses down on the right pop-out button 03. When the right pop-out button 03 is pressed down, it pushes the right drive shaft 05 to rotate counterclockwise and releases the lock on the other right end of the charging box 13.

[0040] After charging is complete, the lawnmower body 1 moves away from the charging base plate 19, releases the pressure on the right pop-out button 03, the right drive shaft 05 rotates clockwise to reset, and locks the other right end of the charging box 13 to the charging base plate 19.

[0041] The other end of the right drive shaft 05 is provided with a locking hook 20, and the right end of the charging box 13 is provided with a locking hook groove (not shown in the figure) that matches the locking hook 20. When the right drive shaft 05 rotates, the locking hook 20 can rotate into one end of the locking hook groove and lock the right end of the charging box 13 onto the charging base plate 19, or the locking hook 20 can rotate to the other end of the locking hook groove and release the locking of the right end of the charging box 13.

[0042] The locking and unlocking method of the right drive shaft 05 to the left end of the charging box 13 and the charging base plate 19 via the locking hook 20 is the same as the locking and unlocking method of the left drive shaft 16 to the right end of the charging box 13 and the charging base plate 19 via the locking hook 20, and will not be described again here.

[0043] The right drive shaft 05 is provided with a pressure plate 21, and the right pop-out button 03 is spring-loaded on the pressure plate 21 via a right spring 04.

[0044] The method by which the right pop-out button 03 drives the right transmission shaft 05 to rotate via the right spring 04 and pressure plate 21 is the same as the method by which the left pop-out button 14 drives the left transmission shaft 16 to rotate via the left spring 15, and will not be described again here.

[0045] A right reset torsion spring 06 is sleeved on the right drive shaft 05, and the two ends of the right reset torsion spring 06 are fixedly connected to the right drive shaft 05 and the right bottom cover 07, respectively.

[0046] The method by which the right drive shaft 05 is reset by rotating the right reset torsion spring 06 is the same as the method by which the left drive shaft 14 is reset by rotating the left reset torsion spring 17, and will not be described again here.

[0047] The charging base plate 19 has a pair of concave arc surfaces 22. The two wheels of the lawnmower body 1 are respectively matched and parked on the pair of concave arc surfaces 22. The surfaces of the pair of concave arc surfaces 22 have anti-slip textures. The left bottom cover 18 of the left control component and the right bottom cover 07 of the right control component are respectively installed below the pair of concave arc surfaces 22. The left mounting hole and the right mounting hole are respectively located on the pair of concave arc surfaces 22.

[0048] Preferably, the shape and size of the concave arc surface 22 can be adapted to the shape and size of the wheels on both sides of the lawnmower body 1, so that when the lawnmower body 1 travels to the charging base plate 19, the bottom of its wheels on both sides is precisely embedded in a pair of concave arc surfaces 22, which can provide precise positioning and limiting of the lawnmower body 1, and facilitate subsequent effective docking and charging.

[0049] Please see the appendix Figure 1 The working process and working principle of this utility model are as follows:

[0050] In the initial state, the left and right ends of the other side of the charging case 13 are locked into the mounting holes in the middle of the charging base plate 19 via the left and right control components, respectively. The left reset torsion spring 02 and the right reset torsion spring 12 on one side of the charging case 13 are in a torsional storage state. The right eject button 03 and the left eject button 14 protrude from the right and right mounting holes of the charging base plate 19, respectively.

[0051] When the lawnmower body 1 needs to be charged, the lawnmower body 1 travels to the charging base plate 19, and the two wheels of the lawnmower body 1 stop on a pair of concave arc surfaces 22 respectively. The concave arc surfaces 22 and their anti-slip textures ensure the accuracy and stability of the stopping position of the lawnmower body 1, thereby ensuring effective charging in the future.

[0052] After the lawnmower body 1 stops on the charging base plate 19, the two wheels press down the right pop-out button 03 and the left pop-out button 14 respectively. The right spring 14 and the left spring 15 are compressed and stored. At the same time, the pressure plate 21 is pressed down. When the pressure plate 21 is pressed down, it drives the right drive shaft 05 and the left drive shaft 16 to rotate counterclockwise. At this time, the right reset torsion spring 06 and the left reset torsion spring 17 twist and store power.

[0053] During the counterclockwise rotation of the right drive shaft 05 and the left drive shaft 16, their locking hook 20 rotates to the other end of the locking hook groove, releasing the lock on the charging box 13. Under the elastic force of the left reset torsion spring 02 and the right reset torsion spring 12, the charging box 13 rotates upward around one side of its shaft and pops out, so that the pair of charging base charging plates 11 on the top of the charging box 13 connects with the pair of lawnmower charging connection plates 10 on the bottom of the lawnmower body 1, thereby realizing the charging of the lawnmower body 1.

[0054] After the lawnmower body 1 is fully charged, it moves away from the charging base plate 19, releasing the downward pressure on the right pop-out button 03 and the left pop-out button 14. This allows them to pop upwards through the right and left mounting holes under the elastic force of the right spring 14 and the left spring 15. As the right and left springs 14 and 15 pop upwards, they disengage from the pressure plate 21, causing the right drive shaft 05 and the left drive shaft 16 to rotate clockwise and reset under the elastic force of the right return torsion spring 06 and the left return torsion spring 17, respectively.

[0055] Simultaneously, as the lawnmower body 1 moves away from the charging base plate 19, the bottom of the lawnmower body 1 presses against the other side of the charging box 13, causing the charging box 13 to rotate downwards and enter the mounting hole in the middle of the charging base plate 19. At this time, the left return torsion spring 02 and the right return torsion spring 12 on one side of the charging box 13 twist and store force, and the right drive shaft 05 and the left drive shaft 16 drive the locking hook 20 to rotate synchronously to one end of the locking hook groove when they rotate, locking one side of the charging box 13 in the charging base plate 19, completing one charging process.

[0056] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
