[0044] Referring to Figures 1, 2 and 3, Figure 1 is a schematic diagram of the structure of the safety charging device 10 provided by the present application and the corresponding sweeping robot 20, Figure 2 is a schematic diagram of the exploded structure of the safety charging device 10 provided by the present application, and Figure 3 is a schematic diagram of the exploded structure of the conductive docking module 200 in Figure 2. The safety charging device 10 provided in one embodiment of the present application includes a protective shell 100 and a conductive docking module 200.

[0045] The protective shell 100 is provided with a pressing hole 110 and a protective clearance hole 120. In a specific configuration, the pressing hole 110 and the protective clearance hole 120 penetrate the protective shell 100 along the thickness direction of the protective shell 100, and the pressing hole 110 and the protective clearance hole 120 are staggered. The conductive docking module 200 includes a pressure-bearing mechanism 210 and a conductive mechanism 220. The pressure-bearing mechanism 210 includes a pressure-bearing frame 211 and a pressing member 212. The pressure-bearing frame 211 is rotatably mounted on the protective shell 100. The pressure-bearing frame 211 is connected to the conductive mechanism 220. The pressing member 212 is arranged on the pressure-bearing frame 211 and passes through the pressing hole 110. The pressing member 212 is pressed to drive the pressure-bearing frame 211 to rotate, thereby rotating the conductive mechanism 220 connected to the pressure-bearing frame 211, so that the charging contact 221 on the conductive mechanism 220 passes through the protective clearance hole 120.

[0046] The above-mentioned safe charging device 10 drives the pressure frame 211 to rotate by setting a pressing member 212 to make the charging contact 221 on the conductive mechanism 220 pass through the protective clearance hole 120. When the sweeping robot 20 needs to be charged, the automatic recharging function of the sweeping robot 20 is used to make the sweeping robot 20 patrol to the set position of the safe charging device 10. At this time, the first walking wheel of the sweeping robot 20 presses the pressing member 212, so that the charging contact 221 on the conductive mechanism 220 passes through the protective clearance hole 120 and docks with the conductive member of the sweeping robot 20 for charging. That is, the charging contact 221 of the present application will only pass through the protective shell 100 when the pressing member 212 is touched, and in other cases, the charging contact 221 is hidden under the protective shell 100. Compared with the current charging contact 221 exposed to the outside, it effectively prevents the charging contact 221 from being damaged by accidental touch, thereby reducing the maintenance cost.

[0047] In the specific setting, a pressing piece 212 is provided at one end of the pressure-bearing frame 211, and the other end of the pressure-bearing frame 211 is rotatably installed on the protective shell 100, and a conductive mechanism 220 is provided at the end of the pressure-bearing frame 211 away from the pressing piece 212. Pressing the pressing piece 212 drives the pressure-bearing frame 211 to tilt upward on the side away from the pressing piece 212, so that the charging contacts 221 on the conductive mechanism 220 move out of the protective clearance hole 120 and dock with the conductive parts of the sweeping robot 20 for charging.

[0048] In order to more conveniently realize the rotation of the pressure frame 211 to drive the charging contact 221 on the conductive mechanism 220 to pass through the protective clearance hole 120, in a preferred embodiment, a pressing piece 212 is provided at one end of the pressure frame 211, and a tooth assembly 213 is provided at the other end of the pressure frame 211. The tooth assembly 213 is rotatably mounted on the protective shell 100, and the conductive docking module 200 also includes a gear transmission mechanism 230, which is meshed with the tooth assembly 213 and connected to the conductive mechanism 220. In the specific setting, the gear transmission mechanism 230 is located on the side of the pressure frame 211 where the rotation point is close to the pressing piece 212, and the conductive mechanism 220 is arranged on the side of the gear transmission mechanism 230 away from the tooth assembly 213.

[0049] Through the above arrangement, the pressing member 212 is pressed to transmit pressure through the pressure frame 211, so that the tooth assembly 213 rotates. Taking FIG. 3 as an example, the tooth assembly 213 rotates clockwise, and the gear transmission mechanism 230 meshing with the tooth assembly 213 rotates counterclockwise, so that the conductive mechanism 220 connected to the gear transmission mechanism 230 moves up counterclockwise, allowing the charging contact 221 on the conductive mechanism 220 to pass upward through the protective clearance hole 120 of the protective shell 100. The present application transmits force through the form of gear meshing. On the one hand, it ensures an accurate transmission ratio, so that the transmission accuracy is high, and the transmission process is stable and reliable. On the other hand, the rotation of the gear transmission mechanism 230 can drive the conductive mechanism 220 connected thereto to rise and fall so that the charging contact 221 on the conductive mechanism 220 can be moved out of or into the protective shell 100, which is convenient for the use and protection of the charging contact 221.

[0050] It should be noted that the charging contact 221 includes two, a positive charging contact 221 and a negative charging contact 221, so as to dock with the positive conductive part and the negative conductive part of the charging sweeping robot 20 for charging. In order to save installation space and reduce the volume of components, specifically, the pressure frame 211 includes a bearing body and two rotating rods 2111 spaced apart from the bearing body, a pressing member 212 is installed on the bearing body, and a tooth assembly 213 is provided on the side of the two rotating rods 2111 away from the bearing body, each tooth assembly 213 is correspondingly meshed with a gear transmission mechanism 230, and the two gear transmission mechanisms 230 are respectively connected to the two conductive mechanisms 220, and the positive charging contact 221 and the negative charging contact 221 are respectively provided on the two conductive mechanisms 220. In the specific setting, there are two protective clearance holes 120 on the protective shell 100, and the two protective clearance holes 120 correspond to the positive charging contact 221 and the negative charging contact 221, respectively. The above-mentioned safe charging device 10 realizes the installation of two tooth assemblies 213 by setting the spaced rotating rods 2111, and then realizes the installation of two gear transmission mechanisms 230 and two conductive mechanisms 220, so that the tooth assemblies 213, gear transmission mechanisms 230 and conductive mechanisms 220 arranged in pairs are symmetrically distributed in the horizontal direction, ensuring the beauty of the above-mentioned components and saving space in the vertical direction.

[0051] In order to conveniently realize that the tooth assembly 213 is rotatably mounted on the protective shell 100, the tooth assembly 213 is pivotally connected to the protective shell 100. Specifically, the tooth assembly 213 includes a first fixed shaft 2131 and a rotating tooth 2132. The first fixed shaft 2131 is set on the protective shell 100. The rotating tooth 2132 is sleeved on the first fixed shaft 2131 and can rotate relative to the first fixed shaft 2131. The rotating tooth 2132 is set on the rotating rod 2111 in the pressure frame 211. Through the above arrangement, the rotating tooth 2132 can rotate around the first fixed shaft 2131 to achieve rotation relative to the protective shell 100.

[0052] In order to design the gear transmission mechanism 230 more conveniently, specifically, the gear transmission mechanism 230 includes a transmission body 231 and a transmission tooth 232 disposed on the transmission body 231, the transmission tooth 232 is meshed with the tooth assembly 213, and the transmission body 231 is rotatably mounted on the protective shell 100 and is movably connected to the conductive mechanism 220. Through the above arrangement, the transmission body 231 is rotatably connected to the protective shell 100, and the protective shell 100 provides support for the transmission body 231 to ensure the transmission stability of the gear transmission mechanism 230, and the transmission body 231 is movably connected to the conductive mechanism 220, which increases the swing amplitude of the conductive mechanism 220 and increases the range of motion of the charging contact 221 to adapt to different types of conductive parts in the sweeping robot 20.

[0053] In order to more conveniently realize that the transmission body 231 is rotatably mounted on the protective shell 100 and is movably connected with the conductive mechanism 220, more specifically, the conductive mechanism 220 includes a conductive seat 222, a first elastic member 223, and a charging contact 221 disposed on the conductive seat 222, and the first elastic member 223 is preferably a torsion spring. The transmission body 231 is pivotally connected to the conductive seat 222. In a specific configuration, the gear transmission mechanism 230 also includes a second fixed shaft 233 disposed on the protective shell 100, and the transmission body 231 and the conductive seat 222 can be rotatably sleeved on the second fixed shaft 233 relative to the second fixed shaft 233. The first elastic member 223 is in contact with the transmission body 231 and the conductive seat 222, and the first elastic member 223 can elastically and rotatably support the transmission body 231 and the conductive seat 222. In the specific setting, the first elastic member 223 includes a first body and two elastic rods connected to both sides of the first body. The first body is sleeved on the second fixed shaft 233, and the two elastic rods are respectively in contact with the transmission body 231 and the conductive seat 222.

[0054] Through the above arrangement, pressing down the pressing member 212 causes the tooth assembly 213 to rotate, and the gear transmission mechanism 230 meshing with the tooth assembly 213 rotates in the opposite direction around the second fixed shaft 233, and the gear transmission mechanism 230 squeezes the elastic rod abutting against it, so that another elastic rod squeezes the conductive mechanism 220, and the conductive mechanism 220 rotates and moves upward around the second fixed shaft 233, so that the charging contact 221 on the conductive mechanism 220 passes upward through the protective clearance hole 120 of the protective shell 100. The above-mentioned safe charging device 10 realizes the movable connection between the conductive mechanism 220 and the gear transmission mechanism 230 by setting the second fixed shaft 233 and the first elastic member 223, and also ensures the transmission stability of the gear transmission mechanism 230, with a simple structure, convenient installation, and strong operability.

[0055] In the specific setting, the transmission body 231 is provided with a first accommodating cavity 2311 and a connecting through hole connected to the first accommodating cavity 2311, the second fixed shaft 233 is penetrated by the connecting through hole and part of the second fixed shaft 233 is located in the first accommodating cavity 2311, the first body is sleeved on the second fixed shaft 233 and is located in the first accommodating cavity 2311, and two sleeve rings 224 are spaced apart on the conductive seat 222, the two sleeve rings 224 are sleeved on the second fixed shaft 233, and a clamping channel for clamping the transmission body 231 is formed between the two sleeve rings 224, so that the structure of the gear transmission mechanism 230 and the conductive mechanism 220 is compact, which is conducive to saving space.

[0056] In order to allow the charging contact 221 to quickly pass through the protective shell 100, the conductive mechanism 220 further includes a lifting protrusion 225 and a magnetic attraction member 226 installed on the lifting protrusion 225. The lifting protrusion 225 is arranged on the conductive seat 222. The magnetic attraction member 226 is used to adsorb the charging contact 221. In the specific setting, the magnetic attraction member 226 is arranged on the side of the lifting protrusion 225 away from the conductive seat 222. The magnetic attraction member 226 is preferably a magnet to facilitate the installation of the charging contact 221 and replacement when it is damaged. Through the above setting, the height of the lifting protrusion 225 can be used to reduce the rising distance of the charging contact 221, so that when the pressing member 212 is pressed down, the charging contact 221 can quickly pass through the protective shell 100 to dock and charge the sweeping robot 20.

[0057] In order to strengthen the connection strength between the tooth assembly 213, the gear transmission mechanism 230 and the conductive mechanism 220 and the protective shell 100, the conductive docking module 200 further includes a mounting seat 240 that is detachably connected to the protective shell 100. In a specific setting, the protective shell 100 and the mounting seat 240 can be detachably connected by fasteners such as bolts and screws. The mounting seat 240 includes a mounting body 241 and a mounting plate 242 disposed on the mounting body 241. The mounting body 241 is used to carry the tooth assembly 213. In a specific setting, a receiving groove 2411 is provided on the mounting body 241 to carry part of the tooth assembly 213. The mounting plate 242 abuts against the bottom of the second fixed shaft 233. In a specific setting, there are two mounting plates 242, and the two mounting plates 242 abut against the two ends of the second fixed shaft 233 respectively. The gear transmission mechanism 230 and the conductive mechanism 220 are sleeved on the second fixed shaft 233. Through the above arrangement, the connection stability between the tooth assembly 213, the gear transmission mechanism 230 and the conductive mechanism 220 and the protective shell 100 is strengthened through the mounting seat 240, and the transmission stability is also ensured.

[0058] In order to hide the charging contact 221 under the protective shell 100 in time after charging is completed, the conductive docking module 200 further includes a reset mechanism 250, which includes a reset base 251 and a second elastic member 252. The reset base 251 is arranged on the side of the pressure frame 211 away from the pressing member 212 and is detachably connected to the protective shell 100, and the second elastic member 252 is arranged between the pressure frame 211 and the pressing member 212. In the specific setting, the second elastic member 252 is preferably a spring and has a conical shape, but the second elastic member 252 is not limited to the above-mentioned conical structure, and can also be any geometric shape such as a cylindrical shape or a conical shape.

[0059] Through the above arrangement, when the first walking wheel of the sweeping robot 20 exits the pressing member 212, the pressing member 212 moves upward under the action of the rebound force of the second elastic member 252 to drive the tooth assembly 213 on the pressure frame 211 to rotate counterclockwise, and the gear transmission mechanism 230 meshing with the tooth assembly 213 rotates clockwise around the second fixed axis 233. The gear transmission mechanism 230 enables the conductive mechanism 220 to move downward around the second fixed axis 233 through the first elastic member 223, thereby driving the charging contacts 221 on the conductive mechanism 220 to move downward and be hidden under the protective shell 100.

[0060] It should be emphasized that the charging contacts 221 of the current charging device are exposed, which is not only easy to be damaged by accidental touch, but also current still flows through the exposed charging contacts 221. When the user accidentally touches the charging contacts 221, it will cause harm to the user and affect the user experience.

[0061] Based on this, in order to solve the problem that the charging contacts 221 of the current charging device are exposed and easily hurt the user, refer to Figures 4, 5 and 6. Figure 4 is another exploded structural schematic diagram of the safe charging device 10 provided by the present application, Figure 5 is a structural schematic diagram of the power module 400 and the switch module 500 in Figure 4, and Figure 6 is an enlarged structural schematic diagram of the A in Figure 5. The safe charging device 10 provided by an embodiment of the present application also includes a power module 400 and a switch module 500 electrically connected to the power module 400, a detector 700 and a control module. Among them, the conductive docking module 200 is electrically connected to the power module 400, and the pressing member 212 in the conductive docking module 200 is used to drive the pressure frame 211 to rotate when pressed, so that the charging contact 221 on the conductive mechanism 220 passes through the protective clearance hole 120 and docks with the sweeping robot 20. In the specific setting, the charging contact 221 is connected to the power module 400 through a cable and a conductive spring 227.

[0062] The switch module 500 and the detector 700 are both connected to the control module for communication. The switch module 500 is used to send a first signal when pressed, and the detector 700 is used to detect the distance information between the sweeping robot 20 and itself. The control module controls the power module 400 to connect or disconnect the conductive docking module 200 according to the first signal and the distance information. It should be noted that the switch mechanism 510 is activated when pressed, thereby sending the first signal. It should be emphasized that the power module 400 is electrically connected to the conductive docking module 200 only when the distance information detected by the detector 700 is within a preset range while the switch mechanism sends the first signal.

[0063] In a specific configuration, the safety charging device 10 further includes a base 300, which is used to carry the sweeping robot 20. The switch module 500 includes a switch mechanism 510 and a swing fork 520 connected to the switch mechanism 510, the swing fork 520 is rotatably mounted on the base 300, and the swing fork 520 is used to rotate when subjected to pressure to drive the switch mechanism 510 to start, thereby sending a first signal.

[0064] When the above-mentioned safety charging device 10 is used to charge the sweeping robot 20, the sweeping robot 20 needs to patrol to the set position through its own set automatic recharging function, and the first walking wheel and the first moving wheel of the sweeping robot 20 simultaneously press down the pressing piece 212 and the swing fork 520 accordingly, and the distance information detected by the detector 700 is within the preset range, then the charging contact 221 and the conductive part of the sweeping robot 20 will be correspondingly connected and electrically connected to ensure the accuracy of charging.

[0065] As shown in FIG. 7 , FIG. 7 is an exploded structural schematic diagram of the switch module 500 provided by the present application. In order to more conveniently start the switch mechanism 510 when the swing fork 520 rotates, a preferred embodiment is that the switch mechanism 510 is suspended on the base 300, and 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 mounted on the base 300. Through the above arrangement, the swing fork 520 rotates when subjected to the downward pressure of the first running wheel, and transmits the downward pressure to the switch spring 512. When the switch spring 512 is subjected to external pressure, the circuit is connected. In the specific arrangement, such a switch mechanism 510 is preferably a normally open switch.

[0066] In order to promptly cut off the power to the charging contact 221 after the charging is completed, the switch module 500 further includes a reset elastic member 530, which abuts against the swing fork 520 so that the swing fork 520 has a tendency to swing in a direction 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-mentioned conical structure, and can also be any geometric shape such as a cylindrical shape or a conical shape. Through the above-mentioned setting, when the first moving wheel of the sweeping robot 20 exits the swing fork 520, the swing fork 520 returns to the initial position under the action of the rebound force of the reset elastic member 530, so as to drive the switch spring 512 back to the initial position to disconnect 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.

[0067] In order to better protect the switch module 500, a preferred embodiment is that the base 300 includes a bottom plate 310 and a support plate 320 connected to the bottom plate 310, and an accommodating space is formed between the support plate 320 and the bottom plate 310. The switch mechanism 510 is located in the accommodating space and is connected to the swing fork 520. In a specific setting, the switch mechanism 510 is suspended on the bottom plate 310, and the swing fork 520 is rotatably installed on the bottom plate 310 and part of the swing fork 520 passes through the support plate 320 so as to connect with the first walking wheel in the sweeping robot 20. In a specific setting, the reset elastic member 530 is arranged between the bottom plate 310 and the swing fork 520. Through the above arrangement, the switch mechanism 510, the reset elastic member 530 and part of the swing fork 520 are located in the accommodating space, and only the part of the swing fork 520 that carries the first moving wheel is arranged on the outside of the support plate 320, thereby preventing the cleaning robot 20 from colliding with other components of the switch module 500 and causing damage when patrolling to the preset position.

[0068] It should be noted that the support plate 320 is used to carry the sweeping robot 20, and a mounting through hole 321 is provided on the support plate 320 so that the protective shell 100 can be connected to the support plate 320 through the mounting through hole 321. Specifically, a first card slot and a first card block can be provided on the hole wall of the mounting through hole 321, and a second card block and a second card slot that are compatible with the first card slot and the first card block are provided on the protective shell 100, so that the base 300 and the protective shell 100 can be detachably connected through the cooperation of the card block and the card slot. It should be emphasized that the support plate 320 and the bottom plate 310 can also be detachably connected through the cooperation of the card block and the card slot.

[0069] In order to better provide a mounting point for the swing fork 520, specifically, the switch module 500 further includes a fixing seat 540 disposed on the bottom plate 310, the fixing seat 540 is also located in the accommodation space, the fixing seat 540 includes a base plate 541 and protective walls disposed on both sides of the base plate 541, and an accommodation channel is formed between the two protective walls; the swing fork 520 includes a fork body 521 and two swing shafts 522 spaced apart from the fork body 521, the fork body 521 is connected to the switch mechanism 510 and is located in the accommodation channel, and the two swing shafts 522 are respectively penetrated by two protective walls and can rotate relative to the protective walls. In the specific setting, the top of the fork body 521 passes through the support plate 320 through the first through hole 322 opened in the support plate 320 so as to dock with the first running wheel, and the two ends of the reset elastic member 530 are respectively connected to the fork body 521 and the fixing seat 540. Through the above arrangement, the protective wall of the fixing seat 540 can not only protect the swing fork 520, but also provide a rotation installation point for the swing fork 520, which is conducive to the compactness of various structural parts, thereby saving installation space.

[0070] In order to more conveniently realize the suspension of the switch mechanism 510 on the bottom plate 310, more specifically, the base plate 541 includes a first plate body 5411, a second plate body 5412 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 piece 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, the swing fork 520 also includes a connecting arm 523 arranged on the fork body 521, in a specific setting, the connecting arm 523 is arranged on the side of the fork body 521 away from the swing shaft 522, the fork body 521 is arranged on the second plate body 5412, and the connecting arm 523 passes through the connecting plate body 5413 and is connected to the switch spring piece 512. By arranging the switch spring 512 to penetrate the first plate 5411 at a relatively high position, the switch mechanism 510 is conveniently suspended on the bottom plate 310 , which has a simple structure and is easy to produce.

[0071] In order to facilitate the installation of the switch mechanism 510 on the fixing seat 540, the switch mechanism 510 further includes a circuit board 513, which is arranged on the side of the switch body 511 away from the switch spring 512. The fixing seat 540 also includes a bearing frame arranged on the first plate 5411. The first cavity 5441 of the bearing frame is connected with the clearance through hole opened in the first plate 5411. The switch spring 512 passes through the first cavity 5441 and the clearance through hole and is located on the side of the first plate 5411 close to the second plate. The circuit board 513 is arranged on the bearing frame. In order to strengthen the fixing of the circuit board 513, a plurality of limiting protrusions 545 abutting against the side wall of the circuit board 513 are further arranged on the side of the bearing frame away from the first plate 5411. Two limiting hooks 546 are also arranged on the first plate 5411 and are respectively located on both sides of the circuit board 513. The ends of the limiting hooks 546 abut against the top of the circuit board 513.

In the specific arrangement, the number of first moving wheels corresponding to the switch module 500 is also two. When the two first moving wheels press down the two fork bodies 521 simultaneously and one by one, the power supply module 400 is connected to the conductive docking module 200, thereby preventing power-on caused by accidental contact.

[0073] In order to prevent water or dust from flowing into the corresponding switch module 500 and the conductive docking module 200 through the holes provided on the support plate 320 and the protective shell 100, in a preferred embodiment, the power module 400 further includes a protective cover 600, the protective cover 600 includes a top cover box 610 and a side wall 620 provided on the top cover box 610, the side wall 620 is connected to the base 300 at one end away from the top cover box 610, and the top cover box 610, the side wall 620 and the base 300 form a receiving cavity 630 with one end open, and the receiving cavity 630 is used to accommodate the sweeping robot 20. In the specific setting, the projection of the top cover box 610 on the base 300 covers the area where the first through hole 322 is provided in the protective shell 100 and the support plate 320.
