[0033] REFERENCE Figures 1 to 4The utility model provides a flat storehouse robot with waterproof and dustproof effect, include:

[0034] The shell includes a main body part 11 and two mounting arms 12 extending outward from opposite sides of the main body part 11.

[0035] A plurality of drive assemblies, one mounting arm 12 corresponds to at least one drive assembly, the drive assembly includes drive motor 21 and speed reducer 22, the drive motor 21 is installed to the mounting arm 12, the speed reducer 22 includes speed reducer casing 221 and speed reducer body 222, the speed reducer body 222 is connected to the speed reducer casing 221, and is transmissionally connected with the drive motor 21.

[0036] Screw wheel 30, one speed reducer 22 at least corresponds to one screw wheel 30, and the screw wheel 30 is transmissionally connected with the speed reducer 22.

[0037] Sealing plate 40, the drive motor 21 and the speed reducer casing 221 are sealedly connected through the sealing plate 40.

[0038] The flat storehouse robot with waterproof and dustproof effect in the technical scheme of the utility model includes a shell, a plurality of drive assemblies, a screw wheel 30 and a sealing plate 40, the shell includes a main body part 11 and two mounting arms 12 extending outward from opposite sides of the main body part 11, one mounting arm 12 corresponds to at least one drive assembly, the drive assembly includes a drive motor 21 and a speed reducer 22, the drive motor 21 is installed to the mounting arm 12, the speed reducer 22 includes a speed reducer casing 221 and a speed reducer body 222, the speed reducer body 222 is connected to the speed reducer casing 221, and is transmissionally connected with the drive motor 21, one speed reducer 22 at least corresponds to one screw wheel 30, and the screw wheel 30 is transmissionally connected with the speed reducer 22, the drive motor 21 and the speed reducer casing 221 are sealedly connected through the sealing plate 40, the sealing plate 40 is installed between the drive motor 21 and the speed reducer casing 221, thereby improving the sealing property of the flat storehouse robot with waterproof and dustproof effect, thereby reducing the possibility that water and dust outside enter the inside of the robot, thereby reducing the corrosion to the drive motor 21, the speed reducer 22 and the internal parts of the flat storehouse robot with waterproof and dustproof effect, and further improving the service life of the flat storehouse robot with waterproof and dustproof effect.

[0039] Refer to Figures 1 to 6Specifically, the sealing plate 40 is provided with a bypass hole 41, an output shaft 211 of the driving motor 21 passes through the bypass hole 41 and is in transmission connection with the speed reducer 22, the sealing plate 40 is provided with an annular sealing protrusion 42 on the side facing the mounting arm 12, the sealing protrusion 42 is annularly arranged at the edge of the bypass hole 41, the driving motor 21 is provided with a first sealing groove 212, and the outer circumferential surface of the annular sealing protrusion 42 is in sealing abutment with the first sealing groove 212. Through the cooperation of the annular sealing protrusion 42 and the first sealing groove 212, the sealing between the driving motor 21 and the mounting plate is improved, thereby reducing the possibility of harmful gas, water and dust entering the inside of the driving motor 21, and thereby improving the service life of the driving motor 21.

[0040] Further, the outer diameter of the sealing protrusion 42 is R1, the diameter of the first sealing groove 212 is R2, and R1≤R2. In this way, the interference fit between the sealing protrusion 42 and the first sealing groove 212 is achieved, thereby further improving the sealing between the sealing protrusion 42 and the first sealing groove 212, thereby reducing the possibility of harmful gas entering the inside of the driving motor 21, and thereby improving the service life of the driving motor 21.

[0041] As can be understood, if some harmful gas invades between the driving motor 21 and the sealing plate 40, the gas will either form bubbles between the driving motor 21 and the sealing plate 40, thereby reducing the sealing between the driving motor 21 and the sealing plate 40, or be discharged from the outside or enter the driving motor 21, but if it enters the driving motor 21, it will corrode the internal parts of the driving motor 21, thereby reducing the service life of the driving motor 21. Therefore, in an embodiment, the sealing plate 40 is provided with an annular temporary storage groove 43, and the temporary storage groove 43 is annularly arranged outside the sealing protrusion 42. In this way, even if a small amount of harmful gas enters between the driving motor 21 and the sealing plate 40, it will only flow into the temporary storage groove 43, thereby not forming bubbles between the driving motor 21 and the sealing plate 40, and thereby improving the sealing effect between the driving motor 21 and the sealing plate 40, and thereby improving the service life of the driving motor 21.

[0042] Further, the width of the sealing protrusion 42 is w1, the width of the temporary storage groove 43 is w2, and 0.8w1≤w2≤1.5w1. If w2<0.8w1, it means that the volume of the temporary storage groove 43 is too small, and thereby too little harmful gas can be stored; if w2>1.5w1, it means that the width of the temporary storage groove 43 is too large, thereby reducing the effective contact area between the annular sealing protrusion 42 and the first sealing groove 212, thereby leading to poor sealing and reducing the sealing effect between the driving motor 21 and the sealing plate 40.

[0043] In an embodiment, the maximum diameter of the output shaft 211 of the driving motor 21 is R3, the diameter of the avoiding through hole 41 is R4, and the height of the sealing protrusion 42 is h, and R4>R3+h. It can be understood that R4>R3+h, so that even if the sealing protrusion 42 is deformed to the maximum, it will not interfere with the output shaft 211 of the driving motor 21, thereby improving the stability and reliability of the driving motor 21 during operation, thereby improving the stability and reliability of the flat warehouse robot with waterproof and dustproof effect.

[0044] In an embodiment, the sealing plate 40 is provided with a first abutting surface 401, a second abutting surface 402 and a third abutting surface 403 arranged continuously on the side facing the driving motor 21, the first abutting surface 401 is in sealing abutment with the driving motor 21, the second abutting surface 402 and the third abutting surface 403 are in sealing abutment with the mounting arm 12, and the first abutting surface 401, the second abutting surface 402 and the third abutting surface 403 are in a stepped shape. By arranging the first abutting surface 401, the second abutting surface 402 and the third abutting surface 403 in a stepped shape, the sealing abutment area between the sealing plate 40 and the driving motor 21 and the mounting arm 12 is increased, thereby improving the sealing effect between the sealing plate 40 and the driving motor 21 and the mounting arm 12, thereby reducing the possibility of harmful gases, water and dust entering the inside of the driving motor 21 and the main body 11, thereby improving the service life of the flat warehouse robot with waterproof and dustproof effect.

[0045] Further, the flat warehouse robot with waterproof and dustproof effect further comprises a sealing ring, the mounting arm 12 is provided with an annular second sealing groove 121 on the side facing the sealing plate 40, and the sealing ring is clamped between the annular second sealing groove 121 and the third abutting surface 403. By arranging the sealing ring, the sealing effect between the mounting arm 12 and the sealing plate 40 is further improved, thereby further reducing the possibility of harmful gases, water and dust entering the inside of the flat warehouse robot with waterproof and dustproof effect, thereby reducing the corrosion of the internal parts of the flat warehouse robot with waterproof and dustproof effect, thereby improving the service life of the flat warehouse robot with waterproof and dustproof effect.

[0046] In an embodiment, the sealing plate 40 is provided with a first mounting hole 44 and a second mounting hole 45, the sealing plate 40 is connected to the driving motor 21 through the first mounting hole 44, the mounting arm 12 and the reduction shell 221 are both provided with a third mounting hole 221a, and the sealing plate 40 is clamped and sealed between the mounting arm 12 and the reduction shell 221 through the second mounting hole 45 and the third mounting hole 221a.

By providing the limiting protrusion 46 and the limiting groove 221b, the possibility of deviation between the sealing plate 40 and the driving motor 21, the mounting arm 12 and the reduction shell 221 is prevented, thereby facilitating the installation of the user, improving the sealing effect between the sealing plate 40 and the driving motor 21 and the reduction shell 221, and prolonging the service life of the flat warehouse robot with waterproof and dustproof effect.
