DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 5 As shown, the present invention provides a logistics cargo transfer vehicle with a convenient unloading function, including a shell 1, a rear baffle 5 is fixedly connected to the top outer wall of the shell 1, a stabilizing mechanism 4 is provided on the bottom outer wall of the shell 1, and a composite mechanism 2 is provided on the inner wall of the shell 1; the composite mechanism 2 includes a motor 203, an output shaft of the motor 203 is fixedly connected to a rotating shaft 212, an inner wall of the rotating shaft 212 is elastically connected to a clamping block 214 through a connecting spring 213, an outer wall of the rotating shaft 212 is slidably connected to a moving rod 216, an outer wall of the moving rod 216 is fixedly connected to a protrusion 217, and an outer wall of the moving rod 216 is fixedly connected to a protrusion 217. A card slot 215 is provided, and the inner wall of the shell 1 is rotatably connected to a rotating block 209, and the outer wall of the rotating block 209 is connected to a rotating wheel 207 through a traction rope 208. The outer wall of the rotating wheel 207 is provided with a groove A210, and the outer wall of the rotating wheel 207 is fixedly connected to a side plate 202. The inner wall of the shell 1 is rotatably connected to a threaded rod 204, and the outer wall of the threaded rod 204 is provided with a groove B211. The outer wall of the threaded rod 204 is threadedly connected to a moving block 205, and the outer wall of the moving block 205 is hinged to the bottom plate 201 through a connecting rod 206. A limiting component 3 is provided on the inner wall of the rear baffle 5.

[0029] The above scheme is adopted: the shell 1 is the main body of the logistics cargo transfer vehicle, and the cargo can be placed on the bottom plate 201 for transportation. Universal wheels are arranged under the shell 1, and a handle is arranged on the outer wall of the tailgate 5. The operator can push the handle to move the shell 1 for transportation; through the composite mechanism 2, one end of the bottom plate 201 can be lifted when unloading is required, and the cargo will slide down to the ground along with the inclined bottom plate 201 to complete the unloading, and the operator does not need to manually carry the cargo, which is more convenient; and the composite mechanism 2 can drive the side panels 202 on both sides to flip over. When loading, the side panels 202 can be flipped down and opened to facilitate loading. After loading is completed, the side panels 202 can be flipped upward to prevent the cargo from falling during transportation; the output shaft of the motor 203 is fixedly connected to the rotating shaft 212, and when the motor 203 is turned over, the side panels 202 can be turned over to prevent the cargo from falling during transportation. When the machine 203 is started, it can drive the rotating shaft 212 to rotate, providing power for the operation of the entire composite mechanism 2; the moving rod 216 can only slide horizontally on the outer wall of the rotating shaft 212 and cannot rotate independently, and through the clamping block 214 and the clamping slot 215, the moving rod 216 can be driven to rotate synchronously when the rotating shaft 212 rotates; the clamping slot 215 is provided with two groups, and the moving rod 216 can be moved to two positions for fixing. When the moving rod 216 moves to the position corresponding to the clamping slot 215 and the clamping block 214, the connecting spring 213 will drive the clamping block 214 to pop out and clamp with the clamping slot 215 due to the elastic force. When the moving rod 216 needs to be moved, the clamping block 214 can be pressed to make it disengage from the clamping slot 215, so that the limit of the moving rod 216 can be released and it can be moved.

[0030] like Figures 2 to 5 As shown, the motor 203 is fixedly connected to the outer wall of the bottom end of the shell 1, one end of the connecting spring 213 is fixedly connected to the outer wall of the block 214, the other end of the connecting spring 213 is fixedly connected to the inner wall of the rotating shaft 212, the rotating wheel 207 is rotatably connected to the inner wall of the shell 1, and the two ends of the traction rope 208 are respectively fixedly connected to the outer walls of the rotating wheel 207 and the rotating block 209; the block 214 is slidably connected to the inner wall of the rotating shaft 212, the block 214 is engaged with the card slot 215, the moving rod 216 passes through the outer wall of the shell 1, and the protrusion 217 is plugged into the groove A210 and the groove B211; the side plate 202 is rotatably connected to the inner wall of the shell 1, the bottom plate 201 is rotatably connected to the inner wall of the shell 1, the moving block 205 is slidably connected to the inner wall of the shell 1, one end of the connecting rod 206 is hinged to the outer wall of the bottom end of the bottom plate 201, and the other end of the connecting rod 206 is hinged to the outer wall of the moving block 205.

[0031] The above scheme is adopted: when the moving rod 216 moves, the protrusion 217 moves synchronously, and when one set of the slots 215 is engaged with the block 214, the protrusion 217 will be engaged with the groove A210, and the rotation of the shaft 212 and the moving rod 216 can drive the rotating block 209 to rotate, and because the protrusion 217 is out of contact with the groove B211 at this time, it will not drive the threaded rod 204 to rotate; the outer wall of the rotating block 209 is provided with two sets of traction ropes 208, and the two sets of traction ropes 208 are respectively fixed to the outer walls of the rotating wheels 207 on both sides, and the two sets of traction ropes 208 are rotated. The outer wall of the block 209 is arranged in an alternating manner front to back, one group of traction ropes 208 is wound from the top of the rotating block 209 to the rotating wheel 207, and the other group of traction ropes 208 is wound from the bottom of the rotating block 209 to the other group of rotating wheels 207. When the moving rod 216 drives the rotating block 209 to rotate, the traction ropes 208 will pull the rotating wheels 207 on both sides to rotate at the same time, and the two groups of rotating wheels 207 can rotate in opposite directions or at the same time. Since the two groups of rotating wheels 207 are respectively fixed to the two corresponding side panels 202, the two groups of side panels 202 can be driven to flip upward or downward at the same time.

[0032] like Figures 2 to 5 As shown in the figure, when the moving rod 216 moves to another set of slots 215 and engages with the block 214, the protrusion 217 will engage with the groove B211, thereby driving the threaded rod 204 to rotate. Since the outer wall of the moving rod 216 does not contact the inner wall of the rotating block 209, and the protrusion 217 is out of contact with the groove A210 at this time, it will not drive the rotating block 209 to rotate; when the threaded rod 204 rotates, it will drive the moving block 205 to move. Since the moving block 205 can only be moved inside the shell 1, The threaded rod 204 can rotate forward or reversely to drive the moving block 205 to move horizontally. When the moving block 205 moves toward one side of the motor 203, the connecting rod 206 and its hinged end move synchronously, and the end of the connecting rod 206 hinged to the bottom plate 201 will flip upward and lift the bottom plate 201. Since one end of the bottom plate 201 is rotatably connected to the inner wall of the shell 1, the connecting rod 206 can drive the bottom plate 201 to flip upward to an inclined state, such as Figure 2 As shown, the goods on the bottom plate 201 can be automatically slid down for unloading; when the threaded rod 204 is reversed to move the moving block 205 to the side away from the motor 203, the bottom plate 201 will flip down to a horizontal state for loading; therefore, when loading is required, the side plates 202 on both sides can be lowered separately, and the bottom plate 201 can be kept in a horizontal state for loading; when unloading, the side plates 202 on both sides can be kept stationary, and the bottom plate 201 can be lifted separately for unloading, which is more flexible, has simple operation steps, and is easy to use.

[0033] like Figure 6As shown, the limit assembly 3 includes a block 303, which is elastically connected to the inner wall of the rear baffle 5 through a return spring 302, and the outer wall of the block 303 is fixedly connected with a pull rod 301; the block 303 is slidably connected to the inner wall of the rear baffle 5, one end of the return spring 302 is fixedly connected to the inner wall of the rear baffle 5, and the other end of the return spring 302 is fixedly connected to the outer wall of the block 303; the pull rod 301 passes through the outer wall of the rear baffle 5, and the block 303 contacts the outer wall of the side panel 202.

[0034] The above scheme is adopted: when the side plate 202 is in a vertical state, the stopper 303 pops out under the elastic force of the return spring 302, and its straight surface contacts the outer wall of the side plate 202, which can limit the side plate 202 to keep it in a vertical state. When the moving rod 216 moves to the point where the protrusion 217 is engaged with the groove B211, the rotating block 209 cannot be limited and can rotate. The limit assembly 3 can prevent the two sets of side plates 202 from turning down. When it is necessary to release the limit of the side plate 202 and unfold the side plate 202 downward for loading, the pull rod 301 can be pulled to allow the stopper 303 to overcome the return spring 301. The elastic force of the positioning spring 302 moves toward the inner wall of the rear baffle 5, thereby breaking away from the contact with the outer wall of the side panel 202. At this time, the side panel 202 can rotate freely, and the composite mechanism 2 can drive the side panel 202 to flip down and open; when the pull rod 301 is released, the return spring 302 will push the stopper 303 back to its original position, and the curved surface of the stopper 303 will face both sides. In the process of the side panel 202 flipping upward to a vertical state, it will squeeze the curved surface of the stopper 303, causing it to move toward the inner wall of the rear baffle 5. After it is completely flipped to the vertical state, the stopper 303 pops out to limit it.

[0035] like Figure 7 As shown, the stabilizing mechanism 4 includes a stabilizing plate 401, which is elastically connected to the bottom outer wall of the shell 1 through a telescopic spring 402, a fixing rod 403 is fixedly connected to the top outer wall of the stabilizing plate 401, a slot 404 is provided on the outer wall of the fixing rod 403, a pedal 405 is fixedly connected to the outer wall of the fixing rod 403, a fixing block 406 is fixedly connected to the outer wall of the shell 1, and an insertion rod 408 is elastically connected to the inner wall of the fixing block 406 through a compression spring 407; the fixing rod 403 is slidably connected to the inner wall of the fixing block 406, the two ends of the telescopic spring 402 are respectively fixedly connected to the outer walls of the shell 1 and the stabilizing plate 401, and the insertion rod 408 is clamped with the slot 404; one end of the compression spring 407 is fixedly connected to the outer wall of the insertion rod 408, and the other end of the compression spring 407 is fixedly connected to the inner wall of the fixing block 406, and the insertion rod 408 is slidably connected to the inner wall of the fixing block 406.

[0036] The above scheme is adopted: the slots 404 on the outer wall of the fixing rod 403 are provided with two groups, the insert rod 408 on the inner wall of the fixing block 406 is provided with an inclined surface, and the inclined surface is kept facing upward. When not affected by external forces, the insert rod 408 is engaged with one of the groups of slots 404, which can limit the fixing rod 403, thereby fixing the position of the stabilizing plate 401; multiple groups of rubber blocks are arranged under the stabilizing plate 401 to increase the friction with the ground. When the shell 1 moves to transfer logistics goods, the telescopic spring 402 keeps the stabilizing plate 401 at the top and not in contact with the ground due to its own elastic force. At this time, the insert rod 408 is engaged with the slot 404 below; the pedal 405 is fixed to the top outer wall of the fixing rod 403, which is convenient for the operator to adjust the position of the stabilizing plate 401 with his feet, thereby improving the convenience of operation; when the position of the stabilizing plate 401 needs to be adjusted, the pedal 405 can be pressed downward, and the fixing rod 40 3 moves downward synchronously, the slot 404 squeezes the inclined surface of the insertion rod 408, so that the insertion rod 408 moves toward the inner wall of the fixed block 406, thereby driving the stabilizing plate 401 to move downward and contact the ground, and the telescopic spring 402 is stretched by force to increase the contact area between the overall device and the ground, thereby increasing the stability of the shell 1, so as to avoid the damage to the goods caused by the external force when loading and unloading the goods; after adjustment, the insertion rod 408 corresponds to the position of the upper group of slots 404, and the insertion rod 408 is re-engaged in the slot 404 under the action of the compression spring 407, so that the stabilizing plate 401 will not move upward due to the elastic force of the telescopic spring 402; when it is necessary to release the state in which the stabilizing plate 401 is in contact with the ground, the insertion rod 408 can be pulled outward to break away from the slot 404, and the limit of the fixed rod 403 can be released. The telescopic spring 402 will drive the stabilizing plate 401 to automatically move upward and reset due to its own elastic force, so that the shell 1 can be pushed to transport goods.

[0037] The working principle and use process of the present invention:

[0038] If loading is required, the operator can first press the block 214 to release the limit of the moving rod 216, move the moving rod 216 to make the protrusion 217 engage with the groove A210, and the block 214 engage with another set of slots 215, and then pull the pull rod 301 of the limiting assembly 3 to make the block 303 overcome the elastic force of the reset spring 302 and move toward the inner wall of the rear baffle 5 and break away from the contact with the outer wall of the side panel 202. At this time, the motor 203 can be started, and the motor 203 drives the rotating shaft 212 to rotate. The rotation of the rotating shaft 212 and the moving rod 216 drives the rotating block 209 to rotate. The rotating block 209 pulls the wheels 207 on both sides to rotate simultaneously through two sets of traction ropes 208 staggered in the front and back, driving the two sets of side panels 202 to flip down and open at the same time, which is convenient for loading.

[0039] After loading is completed, the motor 203 is started again so that its output shaft drives the rotating shaft 212 to flip, causing the side plate 202 to flip upward to a vertical state. At this time, the stopper 303 pops out under the elastic force of the return spring 302, and its face contacts the outer wall of the side plate 202, limiting the side plate 202 to keep it in a vertical state to prevent the goods from falling during transportation. At this time, the shell 1 can be pushed to transport the logistics goods.

[0040] When the goods need to be unloaded at a suitable location, the operator can press down on the pedal 405, and the fixing rod 403 moves downward synchronously. The slot 404 squeezes the inclined surface of the insertion rod 408, causing the insertion rod 408 to move toward the inner wall of the fixing block 406, thereby driving the stabilizing plate 401 to move downward and contact the ground. The telescopic spring 402 is stretched by force, thereby increasing the contact area between the overall device and the ground, thereby increasing the stability of the shell 1.

[0041] Then, the block 214 is pressed and the moving rod 216 is moved to another set of slots 215 to engage with the block 214. At this time, the protrusion 217 is engaged with the groove B211, and the motor 203 of the composite mechanism 2 is started to drive the threaded rod 204 to rotate. The rotation of the threaded rod 204 drives the moving block 205 to move to one side of the motor 203, and the connecting rod 206 and the hinged end thereof move synchronously. The hinged end of the connecting rod 206 and the bottom plate 201 will flip upward and lift the bottom plate 201, so that the bottom plate 201 flips upward to a tilted state. The goods will slide down to the ground along with the inclined bottom plate 201 to complete unloading; after unloading is completed, the motor 203 is started to reverse the threaded rod 204, and the moving block 205 moves to the side away from the motor 203, and the bottom plate 201 will flip downward to the initial horizontal state, and then the insertion rod 408 of the stabilizing mechanism 4 will be pulled outward to disengage from the slot 404, and the limit of the fixing rod 403 will be released. The telescopic spring 402 will automatically move the stabilizing plate 401 upward and reset due to its own elastic force. At this time, the transfer vehicle can continue to carry out the next transportation task.
