[0045] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 is a structural schematic view of a safety charging device 10 and a corresponding sweeping robot 20 provided by the present application, Figure 2 is an exploded structural schematic view of the safety charging device 10 provided by the present application, Figure 3 is a structural schematic view of a power module 400 and a switch module 500 in Figure 2 , Figure 4 is an enlarged structural schematic view of A in Figure 3 . The safety charging device 10 provided by an embodiment of the present application comprises a base 300, a conductive docking module 200, a power module 400, a detector 700, and a switch module 500.

[0046] The base 300 is used to carry the sweeping robot 20. The conductive docking module 200 is electrically connected with the power module 400. The conductive docking module 200 has a charging contact 221 which is used to dock with the sweeping robot 20. In a specific arrangement, the charging contact 221 is connected with the power module 400 through a cable and a conductive spring 227. The detector 700 is used to detect distance information between the sweeping robot 20 and itself.

[0047] The switch module 500 comprises a switch mechanism 510 and a swing yoke 520 which is connected with the switch mechanism 510. The swing yoke 520 is rotatably installed on the base 300. The swing yoke 520 is used to rotate to drive the switch mechanism 510 to start when it is pressed. The switch mechanism 510 and the detector 700 are in communication connection with the power module 400. The switch mechanism 510 and the detector 700 are used to jointly control the power module 400 to turn on or turn off the conductive docking module 200. In a specific working process, the power module 400 is electrically connected with the conductive docking module 200 when the switch mechanism 510 is started and the distance information detected by the detector 700 is within a preset range.

[0048] The safe charging device 10 controls the connection of the power module 400 and the conductive docking module 200 by the switch mechanism 510 and the detector 700. When the robot 20 needs to be charged, the robot 20 is guided to the set position of the safe charging device 10 by the automatic charging function of the robot 20. At this time, the first moving wheel of the robot 20 presses the swing fork 520, and the swing fork 520 rotates to drive the switch mechanism 510 to start. At the same time, when the distance information detected by the detector 700 is within the preset range, the power module 400 supplies power to the conductive docking module 200. Thus, the charging contact 221 is electrically connected to the conductive part of the robot 20, and in other cases, the charging contact 221 does not carry current, so even if the user accidentally touches the charging contact 221, the user will not be harmed.

[0049] In combination Figure 5 As shown, Figure 5 The switch module 500 is shown in the exploded view. In order to more conveniently realize the rotation of the swing fork 520 to start the switch mechanism 510, a preferred embodiment is that the switch mechanism 510 is suspended on the base 300, the switch mechanism 510 includes a switch body 511 and a switch spring 512 connected to the switch body 511, one end of the swing fork 520 is connected to the switch spring 512, and the other end of the swing fork 520 is rotatably installed on the base 300. Through the above setting, the swing fork 520 rotates when it is pressed by the first moving wheel, and the pressing force is transmitted to the switch spring 512. The switch spring 512 realizes the connection of the circuit when it is pressed by the external force. In the specific setting, the switch mechanism 510 is preferably a normally open switch.

[0050] In order to cut off the power supply of the charging contact 221 in time after the charging is completed, specifically, the switch module 500 further includes a reset elastic member 530, the reset elastic member 530 abuts against the swing fork 520, so that the swing fork 520 has a tendency to swing away from the base 300. In the specific setting, the reset elastic member 530 is preferably a spring and has a conical shape, but the reset elastic member 530 is not limited to the above conical structure, and can be any geometric shape such as a cylindrical shape or a conical shape. Through the above setting, when the first moving wheel of the robot 20 exits the swing fork 520, the swing fork 520 returns to the initial position under the rebounding force of the reset elastic member 530 to drive the switch spring 512 to return to the initial position to realize the disconnection of the circuit, thereby cutting off the electrical connection between the power module 400 and the conductive docking module 200, and realizing the power-off of the charging contact 221.

[0051] It needs to be emphasized that the current exposed charging contact 221 not only carries current, but also the charging contact 221 is not provided with any protection device, so that the charging contact 221 is easy to be damaged by accidental touch, increasing the maintenance cost. Based on this, in order to solve the problem that the current charging device charging contact 221 is exposed and easy to be damaged, increasing the maintenance cost, referring to Figure 6 and Figure 7 , Figure 6 is another explosion structure schematic diagram of the safety charging device 10 provided by the present application, Figure 7 is Figure 6 the explosion structure schematic diagram of the conductive docking module 200 in

[0052] The safety charging device 10 provided by an embodiment of the present application comprises a protective shell 100 and a conductive docking module 200. The protective shell 100 is provided with a pressing hole 110 and a protection accommodation hole 120. In specific arrangement, the pressing hole 110 and the protection accommodation hole 120 penetrate the protective shell 100 along the thickness direction of the protective shell 100, and the pressing hole 110 and the protection accommodation hole 120 are arranged in a staggered manner. The conductive docking module 200 comprises a pressure bearing mechanism 210 and a conductive mechanism 220. The pressure bearing mechanism 210 comprises a pressure bearing frame 211 and a pressing piece 212. The pressure bearing frame 211 is rotatably installed on the protective shell 100, and the pressure bearing frame 211 is connected with the conductive mechanism 220. The pressing piece 212 is arranged on the pressure bearing frame 211 and penetrates the pressing hole 110. The pressing piece 212 is pressed to drive the pressure bearing frame 211 to rotate, so that the conductive mechanism 220 connected with the pressure bearing frame 211 rotates, so that the charging contact 221 on the conductive mechanism 220 penetrates the protection accommodation hole 120.

[0053] The safety charging device 10 described above drives the pressure bearing frame 211 to rotate by pressing the pressing piece 212, so that the charging contact 221 on the conductive mechanism 220 penetrates the protection accommodation hole 120. When the floor cleaning robot 20 needs to be charged, the automatic charging function of the floor cleaning robot 20 is used to let the floor cleaning robot 20 patrol to the set position of the safety charging device 10. At this time, the first walking wheel of the floor cleaning robot 20 presses the pressing piece 212, so that the charging contact 221 on the conductive mechanism 220 penetrates the protection accommodation hole 120 and is connected with the conductive piece of the floor cleaning robot 20 for charging. That is, the charging contact 221 of the present application will penetrate the protective shell 100 only when the pressing piece 212 is touched, and in other cases, the charging contact 221 is hidden below the protective shell 100. Compared with the current exposed charging contact 221, the damage of the charging contact 221 caused by accidental touch is effectively prevented, and the maintenance cost is reduced.

[0054] It should be noted that the safety charging device 10 of the present application needs to be used, and the sweeping robot 20 needs to be patrolled to the set position through the automatic return charging function set by itself. The first walking wheel and the first moving wheel of the sweeping robot 20 correspond to the underground pressing piece 212 and the swing yoke 520 at the same time, and the distance information detected by the detector 700 is within the preset range. Only in this way, the charging contact 221 and the conductive part of the sweeping robot 20 are correspondingly connected and electrically connected to ensure the accuracy of charging.

[0055] In order to better protect the switch module 500, a preferred embodiment, the base 300 includes a bottom plate 310 and a support plate 320 connected with the bottom plate 310, and a containing space is formed between the support plate 320 and the bottom plate 310.

In the specific setting, the switch mechanism 510 is suspended on the bottom plate 310, the swing yoke 520 is rotatably installed on the bottom plate 310 and part of the swing yoke 520 penetrates out of the support plate 320, so as to be connected with the first moving wheel in the sweeping robot 20. In the specific setting, the reset elastic piece 530 is arranged between the bottom plate 310 and the swing yoke 520. Through the above setting, the switch mechanism 510, the reset elastic piece 530 and part of the swing yoke 520 are located in the containing space, and only part of the swing yoke 520 bearing the first moving wheel is arranged outside the support plate 320, so as to avoid the collision between the sweeping robot 20 patrolling to the preset position and other components of the switch module 500, thereby avoiding the damage caused by the collision.

[0056] It should be noted that the support plate 320 is used to bear the sweeping robot 20, and the mounting hole 321 is formed on the support plate 320 so that the protective shell 100 is connected with the support plate 320 through the mounting hole 321. Specifically, the first clamping groove and the first clamping block can be arranged on the hole wall of the mounting hole 321, and the second clamping block and the second clamping groove matched with the first clamping groove and the first clamping block are arranged on the protective shell 100, so as to realize the detachable clamping of the base 300 and the protective shell 100 through the cooperation of the clamping block and the clamping groove. It should be emphasized that the support plate 320 and the bottom plate 310 can also be detachably clamped through the cooperation of the clamping block and the clamping groove.

In a specific arrangement, the top of the yoke body 521 passes through the support plate 320 through the first through hole 322 opened on the support plate 320, so as to be connected with the first moving wheel, and the two ends of the reset elastic member 530 are respectively connected with the yoke body 521 and the fixing seat 540. Through the above arrangement, the protection wall of the fixing seat 540 can not only protect the swing yoke 520, but also provide a rotating mounting point for the swing yoke 520, which is beneficial to the compactness of each structural member, thereby saving the installation space.

[0058] In order to more conveniently realize that the switch mechanism 510 is suspended on the bottom plate 310, more specifically, the base plate 541 comprises a first plate body 5411, a second plate body and a connecting plate body 5413 for connecting the first plate body 5411 and the second plate body 5412, the first plate body 5411 is higher than the second plate body 5412, the switch spring 512 passes through the first plate body 5411 and is located on the side of the first plate body 5411 close to the second plate body 5412, and the swing yoke 520 further comprises a connecting arm 523 arranged on the yoke body 521.
