[0001] The invention relates to the technical field of electric tricycles, and in particular to a carriage dumping mechanism for an electric tricycle. Background Art

[0002] Electric tricycles are highly adaptable, flexible, easy to maintain, and inexpensive, and can be flexibly used on narrow roads. Electric tricycles have a reverse switch that can easily realize reverse and forward driving functions, which is very practical in narrow alleys and lanes. It is very convenient for driving and parking, and is widely used in short-distance transportation fields such as families, urban and rural areas, individual rentals, factories, mining areas, sanitation, and community cleaning.

[0003] In the existing electric tricycle compartment tipping mechanism, when unloading, materials may be piled up on the top of the compartment, and manual pushing of the materials on the top is required to slide down. In addition, when tipping, the center position of the electric tricycle will be changed, causing the front end of the electric tricycle to tilt up.

DETAILED DESCRIPTION

[0025] 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. Specific embodiment one: like Figures 1 to 9 As shown, the present invention provides an electric tricycle carriage tipping mechanism, comprising a carriage 2 mounted on the surface of a frame 1, the frame 1 and the carriage 2 are rotatably connected by a hydraulic cylinder 3, a feeding mechanism 4 for pushing the loading material to be discharged is fixedly connected to the bottom of the carriage 2, a balancing mechanism 5 for balancing the tricycle is slidably connected to the bottom of the carriage 2 and the center position of the feeding mechanism 4, a limiting mechanism 6 for limiting the flipping of the carriage 2 is rotatably connected inside the frame 1, and a rear door 7 is connected to the rear end of the carriage 2. When in use, when the electric tricycle needs to unload, the limiting mechanism 6 is opened to release the limit on the carriage 2, and then the rear door 7 is removed, and then the hydraulic cylinder 3 is started to push the rear end of the carriage 2 to rotate around the rear end of the frame 1 as the center, so that the front end of the carriage 2 is tilted, and at this time, the feeding mechanism 4 pushes the material inside the carriage 2 to slide down along the inclined surface of the carriage 2 to complete the falling work of the material, and at the same time, the balancing mechanism 5 slides forward, so that the center of the electric tricycle moves forward, thereby ensuring the stability of the electric tricycle when unloading.

[0027] The unloading mechanism 4 includes a first sleeve 402 and a pushing assembly connected to the bottom end of the carriage 2 through an eccentric wheel 401. A large piston rod 403 is slidably connected inside the first sleeve 402, and one end of the large piston rod 403 is engaged with the edge of the eccentric wheel 401. A second sleeve 404 is fixedly connected inside the first sleeve 402. A small piston rod 405 with a diameter smaller than the large piston rod 403 is slidably connected inside the second sleeve 404. A connecting rod 406 for driving a push plate 410 to move in a horizontal direction along the surface of the carriage 2 is fixedly connected to one end of the small piston rod 405. The push plate 410 is internally connected with a pushing assembly. When in use, the hydraulic cylinder 3 pushes the front end of the carriage 2 to tilt up while the eccentric wheel 401 remains stationary, and the first sleeve 402 drives the large piston rod The angle of 403 changes with the car body 2. At this time, the large piston rod 403 slides on the outer edge of the eccentric wheel 401, and is squeezed by the eccentric wheel 401 to slide inside the first sleeve 402, so that the large piston rod 403 squeezes the air inside the first sleeve 402 into the inside of the second sleeve 404, thereby pushing the small piston rod 405 to slide inside the second sleeve 404. By setting the diameter of the large piston rod 403 to be larger than the diameter of the small piston rod 405, the sliding distance of the small piston rod 405 inside the second sleeve 404 is greater than the sliding distance of the large piston rod 403 inside the first sleeve 402, so that the small piston rod 405 drives the push plate 410 to move horizontally along the surface of the car body 2 through the connecting rod 406.

[0028] The pushing assembly includes a contact plate 417, an extrusion plate 418, an insertion rod 415 and a flipping mechanism. The connecting rod 406 is connected to the push plate 410 through the flipping mechanism. The push plate 410 is fixedly connected inside with a spring 416 for driving the contact plate 417 to extend and retract. The push plate 410 is slidably connected inside with an insertion rod 415 connected to the insertion rod 415 at a corresponding position of the push plate 410. When in use, when the push plate 410 pushes the material, the force of the material acting on the surface of the push plate 410 will push the contact plate 417 to slide toward the inside of the push plate 410 and squeeze the spring 416, so that the inclined surface of the contact plate 417 squeezes and pushes the extrusion plate 418 to slide toward the center direction of the push plate 410, so that the inclined surface of the extrusion plate 418 squeezes the insertion rod 415, thereby pushing the insertion rod 415 to slide inside the push plate 410, and extending the insertion rod 415 out of the surface of the push plate 410, so that the insertion rod 415 is inserted into the inside of the material.

[0029] The pushing assembly also includes a connecting column 408, a connecting groove 419 and a concave-convex plate 421. The connecting rod 406 is connected to the push plate 410 through the connecting column 408. A second spring sheet 414 is fixedly connected between the inside of the push plate 410 and the bottom surface of the connecting column 408. A limit block 407 for limiting the rotation of the support rod 409 toward the front of the frame 1 is fixedly connected to the surface of the connecting rod 406. A connecting groove 419 for the connecting rod 406 to push the push plate 410 to move toward the rear door 7 is opened on the surface of the carriage 2, and an elastic rubber ring 420 for closing the connecting groove 419 is connected to the inner wall of the connecting groove 419. The surface and the bottom of the push plate 410 are fixedly connected with a concave-convex plate 421. When in use, the concave-convex plate 421 can make the push plate 410 reciprocate up and down when moving. When the push plate 410 is lifted up, the connecting column 408 will press the second spring sheet 414, and then the second spring sheet 414 will push the push plate 410 to reset by pushing the connecting column 408, so that the insert rod 415 swings inside the material to ensure the looseness of the material and thereby reduce the resistance of the material. When the connecting rod 406 slides inside the connecting groove 419, the elastic rubber ring 420 will block the connecting groove 419 to prevent the material from falling through the connecting groove 419. Specific embodiment 2: See also Figures 2 to 5 As shown, the flip mechanism includes a support rod 409, a slide groove 411, a fixed groove 412 and a first spring piece 413. The surface of the connecting rod 406 close to the push plate 410 is rotatably connected to the support rod 409 that is slidably connected to the slide groove 411. The top of the slide groove 411 is provided with a fixed groove 412 on the side facing the rear door 7. The top of the slide groove 411 is fixedly connected to the first spring piece 413, and the first spring piece 413 and the fixed groove 412 are at the same level. When in use, the push plate 410 is lifted to connect The column 408 rotates around the center, and drives the support rod 409 to rotate on the surface of the connecting rod 406 while sliding inside the slide groove 411. When one end of the support rod 409 slides to the top of the slide groove 411, it will squeeze the first spring sheet 413, and then press one end of the push plate 410, and cooperate with the thrust of the first spring sheet 413 on one end of the support rod 409 to clamp one end of the support rod 409 into the interior of the fixed groove 412, thereby changing the push plate 410 from a vertical state to a horizontal state, providing a seat for the passenger. Specific embodiment three: See also Figure 6As shown, the balancing mechanism 5 includes a storage box 505 connected to the frame 1 through a connecting shaft 501, a counterweight 502 is slidably connected to the surface of the connecting shaft 501, and a rope 504 connected to the bottom end of the front of the car 2 is connected to the surface of the counterweight 502, one end of the rope 504 passes through the interior of the car 2, and a pulley 503 for guiding the forward direction of the rope 504 is rotatably connected to the surface of the car 2. When in use, by tilting the front end of the car 2, the counterweight 502 can be dragged to slide on the surface of the connecting shaft 501 through the rope 504, so that the center of the electric three-wheeler moves forward, thereby ensuring the stability of the electric three-wheeler when unloading materials, and the car 2 is towing When the rope 504 is pulled back, the pulley 503 guides the rope 504, so that the force of the rope 504 dragging the counterweight 502 can be reduced. The connecting shaft 501 is inclined, so that when the carriage 2 is reset, the counterweight 502 will slide into the interior of the storage box 505 along the surface of the connecting shaft 501, so that the counterweight 502 returns to the top of the rear wheel and increases the weight of the rear end of the electric tricycle. When the electric tricycle passes over an uneven road surface, the weight of the counterweight 502 can effectively reduce the electric tricycle from bouncing upward, and the storage box 505 can support the counterweight 502 to prevent the counterweight 502 from crushing the connecting shaft 501 when the electric tricycle falls.

[0032] See also Figure 7 and Figure 8 As shown, the limiting mechanism 6 includes a half gear ring 602 connected to a half gear 601 and a frame 1, one end of the half gear ring 602 is fixedly connected to a movable handle 603 for driving the half gear ring 602 to rotate, and one end of the half gear 601 is fixedly connected to a gear 604 for driving the rack 605 to move in the horizontal direction. When in use, the movable handle 603 is pulled to drive the half gear ring 602 to rotate, and the half gear 601 and the gear 604 are driven to rotate synchronously through the engagement of the half gear ring 602 and the half gear 601, and the rack 605 is driven to move in the horizontal direction through the rotation of the gear 604, so that one end of the rack 605 slides out of the interior of the carriage 2, thereby releasing the limit on the carriage 2.

[0033] See also Fig. 9 As shown, the rear door 7 includes a door cover 701 and a limiting sleeve 703 connecting the vehicle body 2; a plug plate 702 connected to the limiting sleeve 703 is fixedly connected to the bottom end of the surface of the door cover 701; latches 704 are slidably connected to both sides of the top of the door cover 701; a connecting sleeve 705 for connecting to the latch 704 is fixedly connected to one end of the vehicle body 2; when in use, the latch 704 is slid out of the interior of the connecting sleeve 705, and then the door cover 701 is lifted to make the plug plate 702 slide out of the interior of the limiting sleeve 703, thereby removing the door cover 701 from the surface of the vehicle body 2.

[0034] Working principle: first slide the latch 704 out of the interior of the connecting sleeve 705, then lift the door cover 701, so that the plug plate 702 slides out of the interior of the limiting sleeve 703, thereby removing the door cover 701 from the surface of the carriage 2, and then pull the movable handle 603 to drive the half gear ring 602 to rotate, and through the meshing of the half gear ring 602 and the half gear 601, drive the half gear 601 and the gear 604 to rotate synchronously, and through the rotation of the gear 604, drive the rack 605 to move in the horizontal direction, so that one end of the rack 605 slides out of the interior of the carriage 2, thereby releasing the limit on the carriage 2, and start the hydraulic cylinder 3 to push the rear end of the carriage 2 to rotate around the rear end of the frame 1, so that the front end of the carriage 2 is tilted, and the eccentric wheel 401 remains stationary, and the first sleeve 402 is driven The large piston rod 403 changes its angle along with the carriage 2. At this time, the large piston rod 403 slides on the outer edge of the eccentric wheel 401, and is squeezed by the eccentric wheel 401 to slide inside the first sleeve 402, so that the large piston rod 403 squeezes the air inside the first sleeve 402 into the inside of the second sleeve 404, thereby pushing the small piston rod 405 to slide inside the second sleeve 404. By setting the diameter of the large piston rod 403 to be larger than the diameter of the small piston rod 405, the sliding distance of the small piston rod 405 inside the second sleeve 404 is greater than the sliding distance of the large piston rod 403 inside the first sleeve 402, so that the small piston rod 405 drives the push plate 410 along the carriage through the connecting rod 406. 2 surface moves horizontally, when the push plate 410 pushes the material, the force of the material on the surface of the push plate 410 will push the contact plate 417 to slide inside the push plate 410 and squeeze the spring 416, so that the inclined surface of the contact plate 417 squeezes and pushes the squeezing plate 418 to slide toward the center direction of the push plate 410, so that the inclined surface of the squeezing plate 418 squeezes the insertion rod 415, thereby pushing the insertion rod 415 to slide inside the push plate 410, and the insertion rod 415 extends out of the surface of the push plate 410, so that the insertion rod 415 is inserted into the inside of the material, and the push plate 410 can make a reciprocating motion up and down when moving through the concave-convex plate 421. When the push plate 410 is lifted up, the connecting column 408 presses the second spring sheet 414, and then the second spring sheet 414 pushes the connecting column 408 to press the second spring sheet 414. The connecting column 408 pushes the push plate 410 to reset, so that the insert rod 415 swings inside the material to ensure the looseness of the material and thereby reduce the resistance of the material. When the connecting rod 406 slides inside the connecting groove 419, the elastic rubber ring 420 will block the connecting groove 419 to prevent the material from falling through the connecting groove 419. When the electric tricycle is carrying people, the push plate 410 is lifted and rotated around the connecting column 408, and the support rod 409 is driven to rotate on the surface of the connecting rod 406 while sliding inside the slide groove 411. When one end of the support rod 409 slides to the top of the slide groove 411, it squeezes the first spring sheet 413, and then presses one end of the push plate 410, and cooperates with the thrust of the first spring sheet 413 acting on one end of the support rod 409.One end of the support rod 409 is inserted into the interior of the fixing groove 412, so that the push plate 410 is changed from a vertical state to a horizontal state to provide a seat for the passenger. The tilting of the front end of the carriage 2 can pull the pulley 503 to slide on the surface of the connecting shaft 501 through the rope 504, so that the center of the electric tricycle moves forward, thereby ensuring the stability of the electric tricycle when unloading. When the carriage 2 drags the rope 504, the pulley 503 guides the rope 504, which can reduce the force of the rope 504 dragging the counterweight 502. The connecting shaft 501 is inclined. When the carriage 2 is reset, the counterweight 502 will slide into the storage box 505 along the surface of the connecting shaft 501, so that the counterweight 502 returns to the top of the rear wheel and increases the weight of the rear end of the electric tricycle. When the electric tricycle passes through an uneven road surface, the weight of the counterweight 502 can effectively reduce the electric tricycle from bouncing upward, and the storage box 505 can support the counterweight 502 to prevent the counterweight 502 from crushing the connecting shaft 501 when the electric tricycle falls. In this way, the use process of the electric tricycle carriage tipping mechanism is completed.
