If the battery power of the walking motor is insufficient, the walking motor is damaged, or the mobile robot freezes during use, and at this time the intelligent mobile robot is on a slope or has a load, the intelligent mobile robot may experience a situation of slipping or tipping over.

[0022] Such as Figures 1 to 3As shown in the figure, a mobile robot, the mobile robot includes a body, the mobile robot can be a floor sweeping robot, a mopping robot, a disinfection robot, a guiding robot, etc., the body includes a control module, a working module, a driving module, etc., the body includes a housing 1 and a sliding cover device, the sliding cover device includes a sliding cover base 2 and a sliding cover assembly, the sliding cover base 2 is provided with a guide rail 3 and a receiving cavity 4, the guide rail 3 is used to guide the sliding cover assembly to slide on the sliding cover base 2 to cover or expose the receiving cavity 4; the sliding cover assembly includes a sliding cover 5, a telescopic member and a fixing member 6, the sliding cover 5 is located at the opening of the receiving cavity 4 and has the same shape as the opening of the receiving cavity 4. If the opening of the receiving cavity 4 is rectangular, the shape of the sliding cover 5 is also rectangular. The telescopic member and the fixing member 6 are respectively arranged on both sides of the sliding cover 5, which can be the upper and lower sides of the sliding cover 5 or the left and right sides of the sliding cover 5. The telescopic member and the fixing member 6 cooperate with the housing 1 to lock the sliding cover 5 to the sliding cover base 2, and the telescopic member unlocks the sliding cover 5 from the sliding cover base 2 by telescoping on the sliding cover 5. The mobile robot described in this application shields the receiving cavity 4 through the sliding cover 5 to protect the charging interface 15 located in the receiving cavity 4, preventing too much dust from adhering to the charging interface 15 when it is not in use and affecting the charging efficiency of the mobile robot; the mobile robot fixes the sliding cover 5 on the sliding cover base 2 through the telescopic member and the fixing member 6, facilitating the separation of the sliding cover 5 from the sliding cover base 2.

[0023] As one of the implementation manners, the guide rails 3 are respectively arranged on the left and right sides of the receiving cavity, and the guide rails 3 are arranged obliquely downward. The two sides of the sliding cover 5 are provided with sliding pins 7 that cooperate with the guide rails 3. When the sliding cover 5 wants to expose the receiving cavity 4, the sliding cover 5 slides obliquely downward along the guide rails 3 through the sliding pins 7. When the sliding cover 5 wants to cover the receiving cavity 4, the sliding cover 5 slides obliquely upward along the guide rails 3 through the sliding pins 7. The guide rails 3 can also be arranged horizontally and obliquely forward, in which case the guide rails 3 are respectively arranged on the upper and lower sides of the receiving cavity 4, and at this time the sliding cover 5 moves horizontally along the guide rails 3 through the sliding pins 7. The mobile robot moves the sliding cover 5 through the guide rails 3 to improve the moving speed of the sliding cover 5.

[0024] As one of the implementation manners, a strip-shaped protrusion 8 is provided at the upper end of the inner side surface of the sliding cover 5. The strip-shaped protrusion 8 makes the side view of the sliding cover 5 in a shape of "7". The two side surfaces of the strip-shaped protrusion 8 are in the same plane as the left and right side surfaces of the sliding cover 5, that is, the horizontal length of the strip-shaped protrusion 8 is equal to the horizontal length of the sliding cover 5. The sliding pins 7 are respectively located on the two side surfaces of the strip-shaped protrusion 8 and have the maximum vertical distance from the inner side surface of the sliding cover 5, that is, the sliding pins 7 are located at the horizontal endpoints of the strip-shaped protrusion 8 in the shape of "7". Among them, the inner side surface of the sliding cover 5 is the side surface of the sliding cover 5 facing the accommodation cavity 4, and the left and right side surfaces of the sliding cover 5 are the left and right side surfaces of the sliding cover 5 when the sliding cover device is vertically arranged (when the sliding cover device is installed on the robot, the sliding cover of the sliding cover device is vertical to the horizontal plane). The mobile robot supports the sliding cover 5 through the strip-shaped protrusion 8, facilitating the movement of the sliding cover 5.

[0025] As one of the implementation manners, when the sliding cover device is vertically arranged (when the sliding cover device is installed on the robot, the sliding cover of the sliding cover device is vertical to the horizontal plane), the telescopic member is arranged on the upper side surface of the sliding cover 5, and the fixing member 6 is arranged on the lower side surface of the sliding cover 5, that is, the telescopic member, the fixing member 6 and the sliding pins 7 are respectively located on four different side surfaces of the sliding cover 5. When the guide rail 3 is horizontally and obliquely forward arranged, the sliding cover device is also equivalent to being horizontally arranged. At this time, the sliding pins 7 are respectively arranged on the upper and lower side surfaces of the sliding cover 5, and the telescopic member and the fixing member 6 are respectively arranged on the left and right side surfaces of the sliding cover 5. The telescopic member, the fixing member 6 and the sliding pins 7 can be arranged on different side surfaces of the sliding cover 5 according to actual situations, with high flexibility.

[0026] As one of the implementation manners, the telescopic member includes a top block 9, a left limiting arm 10, a right limiting arm 11, a support column 12 and a spring 13. An expansion slot 14 is provided on the sliding cover 5. The left limiting arm 10, the right limiting arm 11, the support column 12 and the spring 13 are arranged in the expansion slot 14. The support column 12 is located between the left limiting arm 10 and the right limiting arm 11. The spring 13 is sleeved on the support column 12, and the number of the springs 13 is the same as the number of the support columns 12. The number of the support columns 12 is two, and the number of the springs 13 is also two. When the top block 9 is subjected to pressure, the top block 9 moves into the expansion slot 14. The left limiting arm 10 and the right limiting arm 11 are used to guide the top block 9 to move vertically downward, reducing the length of the sliding cover 5 in the vertical direction. At this time, the top block 9 will compress the spring 13 in the support column 12, causing the spring 13 to store elastic potential energy. When the pressure on the top block 9 disappears, the spring 13 after storing elastic potential energy will push up the top block 9. At this time, in addition to guiding the top block 9 to move vertically upward, the end protrusions of the left limiting arm 10 and the right limiting arm 11 also play a role in limiting, preventing the telescopic member from detaching from the expansion slot 14. The telescopic member has a simple structure and high practicality.

[0027] As one of the implementation manners, the fixing member 6 includes two bottom blocks. The top block 9 and the bottom blocks are used to lock the sliding cover 5 on the sliding cover base 2. The housing 1 is provided with grooves that cooperate with the top block 9 and the bottom blocks. When the top block 9 and the bottom blocks are located in the grooves, the sliding cover 5 is locked on the sliding cover base 2. When the sliding cover 5 wants to disengage from the sliding cover base 2, the sliding cover 5 applies pressure to the top block 9, causing the top block 9 to retract into the telescopic slot 14. The sliding cover 5 displaces upward by a certain distance, and at the same time drives the bottom blocks to move upward, causing the bottom blocks to disengage from the grooves. Then the sliding cover 5 flips outward, causing the bottom blocks to move away from directly above the grooves. Then the sliding cover 5 can move downward to expose the accommodation cavity 4. The sliding cover 5 is detachably mounted on the sliding cover base 2 through the top block 9 and the bottom blocks, with relatively high flexibility.

[0028] As one of the implementation manners, the accommodation cavity 4 is provided with through holes for placing the charging interface 15. When the charging interface 15 is placed in the through holes, the charging electrodes of the charging interface 15 face the sliding cover 5. That is, the sliding cover 5 is located at the opening of the accommodation cavity 4 and is used to block and expose the accommodation cavity 4. The through holes are located at the bottom relative to the opening of the accommodation cavity 4, so that the charging interface 15 is installed in the accommodation cavity 4 by insertion, preventing too much dust from adhering to the charging interface 15 when it is not in use. The charging interface 15 can also be a camera, which is used to prevent too much dust from adhering to the camera when it is not in use.

[0029] As one of the implementation manners, the sliding cover base 2 is arranged on the housing 1 in an embedded manner. The two sides of the sliding cover base 2 are provided with screw holes, and the sliding cover base 2 is fixed to the housing 1 by screws. The sliding cover base 2 is arranged on the housing 1 of the mobile robot in an embedded manner, preventing the sliding cover device from affecting the rotation of the mobile robot.

[0030] As one of the implementation manners, the guide rail 3 of the sliding cover base 2 and the housing 1 form a guide rail groove 16. When the sliding cover 5 is unlocked from the sliding cover base 2, the sliding cover 5 moves to the bottom of the guide rail groove 16 through the sliding pin 7. The mobile robot restricts the sliding cover 5 from disengaging from the base through the guide rail groove 16, solving the problem that the sliding cover 5 is prone to being lost.

[0031] A sliding cover device, the sliding cover device includes a sliding cover base 2 and a sliding cover assembly. A guide rail 3 and a receiving cavity 4 are provided in the sliding cover base 2. The guide rail 3 is used to enable the sliding cover assembly to slide on the sliding cover base 2 to cover or expose the receiving cavity 4. The sliding cover assembly includes a sliding cover 5, a telescopic member, and a fixing member 6. The telescopic member and the fixing member 6 are respectively arranged on both sides of the sliding cover 5. The telescopic member and the fixing member 6 are used to lock the sliding cover 5 to the sliding cover base 2. The telescopic member unlocks the sliding cover 5 from the sliding cover base 2 by telescoping on the sliding cover 5. The mobile robot described in this application shields the receiving cavity 4 through the sliding cover 5 to protect the charging interface 15 located in the receiving cavity 4, preventing too much dust from adhering to the charging interface 15 when it is not in use and affecting the charging efficiency of the mobile robot. The mobile robot uses the telescopic member and the fixing member 6 to fix the sliding cover 5 on the sliding cover base 2, facilitating the separation of the sliding cover 5 from the sliding cover base 2.

[0032] When the user wants to open the receiving cavity to expose the charging interface, the user can push the sliding cover 5 upward by a certain distance. During the movement of the sliding cover 5, pressure is applied to the top block 9, causing the top block 9 to retract into the telescopic slot 14. During the movement of the sliding cover 5, the bottom block is simultaneously driven upward, causing the bottom block to disengage from the groove under the housing. Then the sliding cover 5 is flipped outward, causing the bottom block to move away from directly above the groove under the housing. Then the sliding cover 5 can move downward along the guide rail groove 16 and be hung at the bottom of the guide rail groove 16 through the sliding pin 7, while exposing the receiving cavity 4. When the user wants to close the receiving cavity to shield the charging interface, the user pushes the sliding cover 5 located at the bottom of the guide rail groove 16 upward along the guide rail groove 16. When the top block 9 is pushed into the groove above the housing, the sliding cover 5 applies pressure to the top block 9, causing the top block 9 to retract into the telescopic slot 14. Then the sliding cover 5 is pushed horizontally inward, causing the bottom block to be directly above the groove under the housing. At this time, the sliding cover 5 is released. Under the action of elastic potential energy, the top block 9 pushes the sliding cover 5 downward, and at the same time pushes the bottom block into the groove under the housing to complete the locking.
