DETAILED DESCRIPTION

[0027] The present invention is further described below through specific implementation methods.

[0028] Reference Figures 1 to 8 As shown, a mobile docking robot that is easy to maintain includes a mobile base 1, a docking roller conveyor mechanism 2, a connecting mechanism 3 and two cameras 4.

[0029] The mobile base 1 comprises a mobile base body 11 and a plurality of running wheels 12 arranged at the bottom of the mobile base body 11 .

[0030] The connecting roller conveyor mechanism 2 is arranged above the mobile base 1 and is used to receive and convey articles. It includes a receiving seat 21 formed with a accommodating cavity 25, a roller transmission component 22 arranged at the bottom of the accommodating cavity 25, a limiting component 23 rotatably arranged on the receiving seat 21 and located in front of the roller transmission component 22 to limit the outward movement of the article, and a limiting handle 24 rotatably arranged at the rear end of the receiving seat 21 to squeeze the article in the limited accommodating cavity 25 downward, wherein the accommodating cavity 25 is used to place the entered article, and its front end is lower than the rear end, so that the accommodating cavity 25 forms a semi-enclosed structure to prevent the article entering the accommodating cavity 25 from escaping from the accommodating cavity 25 backward; a limiting portion 26 for limiting the rotation angle of the limiting handle 24 is formed on the opposite surface of the rear end of the receiving seat 21 and the rotation of the limiting handle 24; the limiting component 23 in front of the roller transmission component 22 cooperates with the accommodating cavity 25 and the limiting handle 24 of the semi-enclosed structure, so that the entered article can be stably placed in the accommodating cavity 25, preventing the article from being opened or lost during transportation, thereby playing a protective function during transportation.

[0031] The limiting assembly 23 includes a limiting seat 231 arranged on the receiving seat 21, a first limiting rod 232 and a second limiting rod 233 rotatably arranged on the limiting seat 231, a rotating motor 234 arranged on the limiting seat 231 and connected to and driving the first limiting rod 231 to rotate, a synchronization rod 235 connected between the first limiting rod 232 and the second limiting rod 233, a connecting shaft 236 arranged on the limiting seat 231 and connected to the second limiting rod 233, and a proximity sensor 237 arranged on the limiting seat 231 for detecting whether an object enters the accommodating cavity. When the proximity sensor 237 senses that the object enters the accommodating cavity 25, the rotating motor 234 controls the first limiting rod 232 to rotate, driving the second limiting rod 233 to rotate until its upper end is located above the roller transmission assembly 22 to limit the object from moving outward from the accommodating cavity 25.

[0032] The connecting mechanism 3 is detachably arranged between the mobile base 1 and the receiving base 21, and includes a supporting base 31 arranged on the top of the mobile base 21, two connecting brackets 22 relatively arranged on the supporting base 31 and connected to the receiving base 21, and a plurality of connecting columns 33 arranged between the supporting base 31 and the top of the mobile base 1, wherein four connecting columns 33 are arranged in a matrix between the supporting base 31 and the top of the mobile base 1, and the connecting columns 33 are respectively connected to the supporting base 31 and the top of the mobile base 1 through connecting bolts 34.

[0033] The support seat 31 includes a support seat body 311 with openings 313 formed on both sides and two sealing plates 312 respectively arranged on both sides of the support seat body 311 for sealing the openings 313. The two connecting columns 33 on the same side are opposite to the openings 313 on the opposite side, and the sealing plate 312 is fixed between the two connecting columns 33 on the same side by locking bolts 35; accordingly, a support step 13 extending downward to support the support seat 31 is formed on the top of the movable base 31, and a first positioning edge 314 that can be supported on the support step 13 is formed at the lower end of the support seat body 311, and a second positioning edge 315 that can be supported on the support step 13 is formed at the lower end of the sealing plate 312. By cooperating with the first positioning edge 314 and the second positioning edge 315 with the support step 13, the rough positioning of the support seat 31 and the movable base 1 can be quickly achieved, which is convenient for the subsequent locking of the bolts.

[0034] The connecting bracket 32 ​​includes a connecting frame 321 extending upward from the supporting seat 31, a connecting plate 322 provided at the upper end of the connecting frame 321 and connected to the receiving seat 21, and a connecting shell 323 sleeved on the outer periphery of the connecting frame 321; and weight-reducing holes 324 are provided on the connecting frame 321 and the connecting plate 322 to reduce the overall weight of the equipment.

[0035] The two cameras 4 are respectively arranged on both sides of the bottom of the connecting roller conveyor mechanism 2, wherein the two cameras 4 are detachably arranged at the bottom of the receiving seat 21 through the mounting plate 41. When the camera is damaged, it is only necessary to remove the mounting plate 41 and take out the camera 4 for maintenance without dismantling the entire machine for maintenance.

[0036] The present application limits the structural composition of the mobile docking robot and sets a connecting mechanism 3 to achieve a detachable connection between the docking roller conveyor mechanism 2 and the mobile base 1, so that the mobile base 1 and the docking roller conveyor mechanism 2 can be used as independent components. When a part is damaged, the corresponding part can be removed for replacement and repair. There is no need to dismantle the entire machine to inspect and repair the corresponding damaged parts as before. The setting of the connecting mechanism 3 allows the undamaged parts to be reassembled with the corresponding parts of the mobile docking robot of the same model. There is no need to wait for the damaged parts to be repaired before working, which effectively improves the transportation efficiency of goods.

[0037] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of implementation of the present utility model. That is, equivalent changes and modifications made according to the scope of the patent application of the present utility model and the contents of the specification should still fall within the scope covered by the patent of the present utility model.
