[0027] Embodiment 1, as Figures 1 to 8 As shown, a battery cabinet AGV vehicle includes a vehicle body 1, a walking assembly 2 is installed under the vehicle body 1, a linear guide rail 3 is installed on the upper surface of the vehicle body 1, a horizontal mounting plate 5 is slidably connected to the linear guide rail 3 through a guide rail slider 4, a rack 6 is fixedly installed on the lower surface of the horizontal mounting plate 5, and the rack 6 and the linear guide rail 3 are arranged parallel to each other, a driving motor 7 is fixedly installed on the vehicle body 1, and a gear 8 is installed on the driving end of the driving motor 7, and the gear 8 is meshed with the rack 6;

[0028] A lifting frame 9 is fixedly mounted on the horizontal mounting plate 5, and vertical mounting plates 10 are movably mounted on both side walls of the inner cavity of the lifting frame 9, and a connecting platform 11 is installed between the vertical mounting plates 10. Screw motors 12 are installed on both sides above the lifting frame 9, and the driving end of the screw motor 12 is transmission-connected to one end of a screw 13 through a coupling, and the screw 13 is vertically mounted on the side wall of the lifting frame 9 through a bearing seat, and a screw nut 14 is fixedly mounted on the outer side of the vertical mounting plate 10, and the screw nut 14 is threadedly connected to the outer surface of the screw 13; an attitude adjustment loading cabinet 15 is installed above the connecting platform 11;

[0029] The posture adjustment loading cabinet 15 includes a welding frame 151, which is connected to the connecting platform 11. A loading cabinet 152 is installed above the welding frame 151. Push plate moving racks 153 are horizontally installed on both side walls of the inner cavity of the loading cabinet 152. A push plate 154 is arranged at the rear end of the inner cavity of the loading cabinet 152. A push plate driving motor 155 is fixedly installed on the rear side of the push plate 154. The driving end of the push plate driving motor 155 is transmission-connected to the rotating shaft 156. The two ends of the rotating shaft 156 are meshed with the push plate moving rack 153 through driving gears.

[0030] Working principle:

[0031] When in use, after the AGV receives the battery replacement instruction, the walking assembly 2 drives the entire vehicle body 1 to move to the corresponding electric vehicle battery replacement position; then the driving motor 7 is controlled to operate to drive the gear 8 to rotate, and then the gear 8 is meshed with the rack 6 to transmit power, so that the entire horizontal mounting plate 5 can be driven to slide horizontally along the linear guide rail 3; at the same time, the screw motor 12 is controlled to operate to drive the screw 13 to rotate, and then the screw nut 14 can be driven to move along the axial direction of the screw 13 through the threaded connection between the screw 13 and the screw nut 14. The push plate 154 is moved to the exit position of the posture adjustment loading cabinet 15 by the vertical mounting plate 10, and then the entire connecting platform 11 can be driven to move vertically up and down, so that the exit position of the posture adjustment loading cabinet 15 is directly opposite to the battery exchange compartment position of the battery exchange cabinet; then the push plate driving motor 155 is controlled to operate to drive the rotating shaft 156 to rotate, so that the driving gears at both ends of the rotating shaft 156 and the push plate moving rack 153 can be engaged to push the entire push plate 154 to move to the exit position of the posture adjustment loading cabinet 15, and then the battery in the posture adjustment loading cabinet 15 can be pushed outward, so that the battery can be directly installed in the energy storage cabinet. The whole process is convenient and fast, does not require manual handling, and can carry heavy batteries, and there is no regional restriction.

[0032] Embodiment 2, as a further preferred embodiment of embodiment 1, the walking assembly 2 includes a group of front wheel assemblies and two groups of rear wheel assemblies, the front wheel assembly includes a swing bridge 21 and two front wheat wheels 22, the middle of the swing bridge 21 is installed on the vehicle body 1 by bolts, front power motors 23 are installed on both sides of the inner cavity of the swing bridge 21, and the driving end of the front power motor 23 is transmission connected to the front wheat wheels 22; the rear wheel assembly includes rear wheat wheels 24 and a rear power motor 25, the rear power motor 25 is fixedly installed on the vehicle body 1, and the driving end of the rear power motor 25 is transmission connected to the rear wheat wheels 24.

[0033] When the entire vehicle body 1 is moved by the walking component 2, adaptive adjustment of a certain angle can be achieved through the swing bridge 21, and the ground contact of the front wheel 22 and the load capacity of the entire vehicle body 1 can be improved. The front power motor 23 drives the front wheel 22 to rotate, and the rear power motor 25 drives the rear wheel 24 to rotate, so as to realize omnidirectional movement of the entire vehicle body 1.

[0034] Embodiment 3, as a further preferred solution of embodiment 1, guide rails 16 are vertically installed on both side walls of the inner cavity of the lifting frame 9, and guide sliders 17 are installed on the outer side of the vertical mounting plate 10, and the vertical mounting plate 10 is slidably connected to the guide rails 16 through the guide sliders 17. The guide rails 16 play a certain guiding role for the vertical mounting plate 10 when it moves up and down, so that the connecting platform 11 can move up and down smoothly to avoid the problem of offset.

[0035] Embodiment 4, as a further preferred solution of embodiment 1, guide plates 157 are installed at both ends of the push plate 154, push plate guide rails 158 are installed horizontally on both side walls of the inner cavity of the loading cabinet 152, and the guide plates 157 are slidably connected with the push plate guide rails 153 through sliders. Therefore, when the push plate driving motor 155 drives the entire push plate 154 to move to the exit position of the posture adjustment loading cabinet 15, the sliding connection of the guide plates 157 on the outer surface of the push plate guide rails 153 can effectively avoid the push plate 154 from deviating during movement, thereby affecting the alignment installation of the battery.

[0036] Embodiment 5, as a further preferred solution of embodiment 1, a limit motor 159 is installed at the bottom of the loading cabinet 152, and the driving end of the limit motor 159 is connected to the driving shaft 1510, and a limit block 1511 is arranged on the outer circumference of the driving shaft 1510, and a through hole is opened on the bottom surface of the loading cabinet 152, and the limit block 1511 corresponds to the through hole. Before the battery is pushed out of the posture adjustment loading cabinet 15, the driving end of the limit motor 159 can be used to drive the driving shaft 1510 to rotate, so that the limit block 1511 protrudes from the through hole, and then the battery is limited, so as to avoid the problem of the battery in the loading cabinet 152 slipping outward during the movement of the vehicle body 1 and the loading cabinet 152.

[0037] Embodiment 6, as a further preferred embodiment of embodiment 1, a visual camera 1512 is fixedly installed above the front end of the loading cabinet 152. The visual camera 1512 can identify and confirm the installation position of the battery to further ensure that the battery can be installed in place.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
