[0014] In an optional embodiment, a linear bearing is provided on the rear cover, and the guide post engages with and passes through the linear bearing.

[0015] In an optional embodiment, a retaining spring is provided on the outer wall of one end of the guide post that passes through the rear cover, the retaining spring being used to hold the linear bearing away from the front cover.

[0016] An embodiment of this utility model also provides a lawnmower charging station, including a base, a column, and the aforementioned charging electrode protection device. The charging electrode protection device includes a front cover, a rear cover, charging electrodes, and an elastic reset member. The front cover and the rear cover are mutually closed and slidably fitted to form a protective chamber. The charging electrodes are disposed on the rear cover and have a charging end located within the protective chamber. A clearance hole is provided through the front cover, and the charging end is aligned with the clearance hole. The front cover is configured to slide towards the rear cover when subjected to force, so that the charging end extends out of the protective chamber through the clearance hole. The elastic reset member is disposed between the front cover and the rear cover and has a tendency to drive the front cover away from the rear cover.

[0019] Anti-slip ribs are protruding on the anti-reverse inclined surface.

[0020] Compared to existing technologies, the charging electrode protection device provided by this utility model, in the non-operating state, keeps the charging end of the charging electrode within a protective cavity enclosed by the front and rear covers, thus providing safety protection for the charging electrode and preventing it from being directly exposed to the environment. When charging is required, the front cover is pushed towards the rear cover by the lawnmower, allowing the charging electrode to extend through the clearance hole and insert into the lawnmower for normal charging. When the lawnmower has finished charging and has left, the front cover, under the action of the elastic reset member, slides back away from the rear cover, causing the charging end of the charging electrode to retract back into the protective cavity. Therefore, the beneficial effects of the charging electrode protection device provided by this utility model include: providing safe protection for the charging electrode, extending its service life, and improving safety.

[0036] Example

[0037] Please see Figure 1 , Figure 1 The diagram shown is a structural schematic of the lawnmower charging station 200 provided in this embodiment.

[0038] The lawnmower charging station 200 provided in this embodiment is used to charge a lawnmower. The lawnmower charging station 200 includes a base 210, a column 220, and a charging electrode protection device 100. The base 210 is used to park the lawnmower, the column 220 is erected on the base 210, and the charging electrode protection device 100 is disposed on one side of the column 220 for charging the lawnmower that has been parked on the base 210.

[0039] In practical applications, when the lawnmower needs to be charged, it moves to the base 210 of the lawnmower charging station 200. When the lawnmower is parked on the base 210, the lawnmower charging station 200 establishes an electrical connection with the lawnmower through the charging electrode protection device 100 to charge the lawnmower.

[0040] Please refer to the following: Figure 2 and Figure 3 , Figure 2 The figure shown is a cross-sectional view of the charging electrode protection device 100 in its initial state. Figure 3 The image shown is a cross-sectional view of the charging electrode protection device 100 in the charging state.

[0041] In this embodiment, the charging electrode protection device 100 includes a front cover 110, a rear cover 120, a charging electrode 130, and an elastic reset member 140. The rear cover 120 is disposed on the column 220. The front cover 110 and the rear cover 120 cover each other and slide together to form a protection chamber 150. The front cover 110 protrudes from one side surface of the column 220.

[0042] The charging electrode 130 is disposed on the rear cover 120, and the charging electrode 130 has a charging end 131 located in the protective chamber 150. A clearance hole 111 is provided through the front cover 110, and the charging end 131 is aligned with the clearance hole 111.

[0043] The front cover 110 is configured to slide toward the rear cover 120 when subjected to force, so that the charging terminal 131 extends out of the protective chamber 150 through the clearance hole 111; the elastic reset member 140 is disposed between the front cover 110 and the rear cover 120 and has a tendency to drive the front cover 110 to slide away from the rear cover 120.

[0044] In this embodiment, there are two charging electrodes 130, which are arranged side by side. In fact, the charging electrodes 130 also have an input terminal that passes through the rear cover 120, and the input terminal is used to connect to the power supply circuit of the lawnmower charging pile 200.

[0045] Understandably, the charging electrode protection device 100 is in a state of... before the lawnmower moves to contact the front cover 110. Figure 2 The initial state shown is such that the charging end 131 of the charging electrode 130 is located in the protective chamber 150 formed by the front cover 110 and the rear cover 120.

[0046] That is, in the initial state, the closing structure of the front cover 110 and the rear cover 120 provides safety protection for the charging electrode 130, preventing the charging electrode 130 from being directly exposed to the environment, preventing the charging electrode 130 from being corroded, improving the service life of the charging electrode 130, and eliminating safety hazards.

[0047] In practical applications, as the lawnmower moves on the base 210, it pushes the front cover 110 of the charging electrode protection device 100 toward the rear cover 120. During this process, the charging end 131 of the charging electrode 130 gradually approaches and passes through the clearance hole 111 on the front cover 110, and the elastic reset member 140 is gradually compressed and accumulates elastic potential energy.

[0048] When the lawnmower is positioned on the base 210, the charging electrode 130 extends to its maximum stroke relative to the front cover 110 and is inserted into the lawnmower. The charging electrode protection device 100 is then in the correct position. Figure 3 The charging status is shown. In this status, the lawnmower can be charged via the power supply circuit of the lawnmower charging station 200.

[0049] As the lawnmower completes charging and leaves the base 210, the elastic reset member 140 gradually releases its elastic potential energy, causing the front cover 110 to slide away from the rear cover 120. During this process, the charging end 131 of the charging electrode 130 gradually retracts into the protective chamber 150 through the clearance hole 111 on the front cover 110.

[0050] When the lawnmower disengages from the front cover 110, the charging electrode protection device 100 returns to its original state. Figure 2 In the initial state shown, the cover structure of the front cover 110 and the rear cover 120 once again provides safety protection for the charging electrode 130.

[0051] To prevent damage to the surface of the lawnmower and the front cover 110, in this embodiment, a buffer layer 112 is provided on the side of the front cover 110 facing away from the rear cover 120. It can be understood that when the lawnmower comes into contact with the front cover 110, the buffer layer 112 can absorb the impact of the lawnmower, preventing the lawnmower from directly colliding with the front cover 110, thus protecting the surface structure of both.

[0052] A detection module is provided on the front cover 110 and / or the rear cover 120 to detect the distance between the front cover 110 and the rear cover 120. In practical applications, the lawnmower charging station 200 uses the detection result of the detection module as the basis for controlling the on / off state of the power supply circuit, so as to ensure that the charging electrode 130 is not energized when the charging electrode protection device 100 is in the initial state, and the charging electrode 130 is energized only when the charging electrode protection device 100 is in the charging state, so as to obtain higher safety.

[0053] Preferably, in this embodiment, the detection module includes a Hall sensor 191 disposed on the rear cover 120 and a magnetic block 192 disposed on the front cover 110. When the charging electrode protection device 100 is in the initial state, the distance between the front cover 110 and the rear cover 120 is relatively large, the Hall sensor 191 cannot sense the magnetic field signal of the magnetic block 192, the power supply circuit of the lawnmower charging pile 200 remains disconnected, that is, the charging electrode 130 is not energized.

[0054] When the charging electrode 130 is in the charging state, the front cover 110 moves to the position closest to the rear cover 120. At this time, the distance between the front cover 110 and the rear cover 120 is the closest. The Hall sensor 191 senses the magnetic field signal of the magnetic block 192, and the lawnmower charging pile 200 controls its power supply circuit to be turned on, so that the charging electrode 130 is energized to realize the normal charging of the lawnmower.

[0055] In this embodiment, in order to prevent the front cover 110 from sliding in an inclined state and causing jamming during the sliding process, so that the charging end 131 of the charging electrode 130 cannot extend into place, the charging electrode protection device 100 further includes a balance bar 160. The balance bar 160 is located in the protection chamber 150 and connected to the rear cover 120. The two ends of the balance bar 160 are slidably engaged with the two ends of the front cover 110 in the length direction.

[0056] It is understandable that the two ends of the stabilizer bar 160 contact and slide with the two ends of the front cover 110 along its length. During the sliding process of the front cover 110 towards or away from the rear cover 120, if the two ends of the front cover 110 tend to have inconsistent sliding strokes along its length, the stabilizer bar 160, due to its high rigidity and strength, can effectively prevent a stroke difference between the two ends of the front cover 110, thus ensuring that the sliding strokes of the two ends of the front cover 110 remain consistent.

[0057] To further improve the smoothness of the sliding process of the front cover 110, the charging electrode protection device 100 provided in this embodiment also includes a guide post 170. One end of the guide post 170 is connected to the front cover 110, and the other end passes through the rear cover 120 along the sliding direction of the front cover 110 and slides with the rear cover 120. Preferably, there are multiple guide posts 170 arranged side by side. Furthermore, the elastic element is a spring, also multiple in number, respectively sleeved on the multiple guide posts 170.

[0058] Preferably, in this embodiment, a linear bearing 180 is provided on the rear cover 120, and a guide post 170 is fitted and passes through the linear bearing 180. One end of a spring sleeved on the guide post 170 abuts against the front cover 110, and the other end abuts against the end of the linear bearing 180 near the front cover 110.

[0059] In order to limit the front cover 110 and prevent the front cover 110 from sliding excessively away from the rear cover 120 and causing it to detach from the rear cover 120, in this embodiment, a retaining ring 171 is provided on the outer side wall of the end of the guide post 170 that passes through the rear cover 120. The retaining ring 171 is used to hold the end of the linear bearing 180 away from the front cover 110.

[0060] Please refer to the following: Figure 4 , Figure 5 and Figure 6 , Figure 4 The diagram shown is a structural schematic of the lawnmower charging station 200 in practical application. Figure 5 As shown Figure 4 Sectional view of the structure Figure 6 As shown Figure 5 An enlarged schematic diagram of region A in the middle.

[0061] In order to guide the lawnmower to be parked in place on the base 210, in this embodiment, the surface of the base 210 is provided with a guide groove 211 for guiding the lawnmower in, and the opening direction of the guide groove 211 is away from the charging electrode protection device 100.

[0062] Specifically, the two opposite sidewalls 2111 of the guide groove are symmetrically arranged, and each sidewall 2111 has multiple guide ramps connected at an angle in sequence. The multiple guide ramps on the two sidewalls 2111 together form a flared structure. The guide groove also has a groove end wall 2112 opposite to the groove opening and connecting the two sidewalls 2111. From the groove opening of the guide groove to the groove end wall 2112, the flared structure gradually narrows.

[0063] In fact, the lawnmower is equipped with two casters 310, which guide the lawnmower to stop on the base 210. Specifically, when the lawnmower moves onto the base 210, the two casters 310 roll into the guide groove under the guidance of the two side walls 2111 of the guide groove, thus guiding the direction and posture of the lawnmower. The lawnmower stops in place when both casters 310 are in contact with the end wall 2112 of the groove, and the charging electrode 130 is inserted into the lawnmower in place.

[0064] To prevent the lawnmower from accidentally leaving the base 210 during charging, in this embodiment, the surface of the base 210 is also provided with an anti-retraction slope 212. The anti-retraction slope 212 is connected to the bottom wall of the guide groove 211, and the anti-retraction slope 212 slopes downward from the end away from the guide groove 211 to the end close to the guide groove 211.

[0065] In fact, the lawnmower is also equipped with two drive wheels 320, which drive the lawnmower to move during rolling. The anti-backlash slope 212 and the guide groove together form a recessed structure on the surface of the base 210. When the two casters 310 are in contact with the groove end wall 2112 of the guide groove, the drive wheels 320 are located in the recessed structure and at least partially in contact with the anti-backlash slope 212.

[0066] Understandably, in this state, if there is no power input to the drive wheel 320, the inclined anti-backward slope 212 can prevent the drive wheel 320 from rolling away from the guide groove, thus achieving the anti-backward effect. In order to further improve the anti-backward effect and prevent the drive wheel 320 from actively rotating and causing the lawnmower to leave the base 210 and slipping on the anti-backward slope 212, in this embodiment, the anti-backward slope 212 is also provided with anti-slip ribs 213.

[0067] In summary, the charging electrode protection device 100 provided in this embodiment can provide safety protection for the charging electrode 130, extend the service life of the charging electrode 130, and improve safety. Benefiting from the beneficial effects of the charging electrode protection device 100, the lawnmower charging pile 200 provided in this embodiment has the characteristics of longer service life and higher safety.

[0068] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
