Description

Technical Field

[0001] This invention relates to the field of cruise control technology, specifically to a cruise control vehicle that facilitates climbing slopes while preventing items from tipping over, and its method of use. Background Technology

[0002] Cruiser vehicles refer to transport vehicles equipped with electromagnetic or optical automatic guidance devices, capable of traveling along a prescribed guidance path, and possessing safety protection and various transfer functions. In industrial applications, they are driverless handling vehicles powered by rechargeable batteries.

[0003] Chinese Patent Publication No. CN115027889B discloses an automatic cruise vehicle climbing device and method, including a travel platform and an AGV vehicle. The travel platform includes an inclined slope, an upper waiting area, and a lower waiting area, with the upper and lower waiting areas located at opposite ends of the inclined slope. During the vehicle's climbing process, prefabricated toothed rails on the slope can assist the vehicle's movement, effectively preventing the vehicle from slipping backward.

[0004] While this patent addresses to some extent the technical problem in the prior art that simply adding a single motor can only enhance the power source of the vehicle, the patent uses prefabricated toothed rails to assist the vehicle's movement. This requires specially setting up the prefabricated toothed rails, increasing the laying cost. Furthermore, during the cruise vehicle's uphill climb, it needs to be specifically aligned with the prefabricated toothed rails. Summary of the Invention

[0005] The purpose of this invention is to provide a cruise trolley that facilitates climbing slopes while preventing items from tipping over, and its method of use. By setting up a climbing component, the climbing wheel body can provide power to the cruise trolley body when climbing a slope, increasing friction and preventing slippage. The cargo frame can rotate, thereby satisfying the requirement that the angle between the cargo frame and the cruise trolley body is adjustable. When the cruise trolley body is climbing a slope, the cargo frame remains horizontal, preventing items from tipping over, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cruise trolley that facilitates climbing slopes while preventing items from tipping over, comprising a cruise trolley body and a cargo frame. One end of the cruise trolley body is hinged to the cargo frame. A movable groove is formed on the upper surface of the cruise trolley body. A lifting component and a climbing component are arranged in the movable groove. The lifting component includes a first cylinder, a sliding block, a lifting plate, a guide rod, and a support wheel frame. The output end of the first cylinder is fixedly connected to the sliding block. The lifting plate is movably connected to the sliding block. One end of the lifting plate is hinged to the cargo frame. Guide rods are symmetrically arranged on one side of the sliding block. The guide rods pass through the movable groove, and the end of the guide rod outside the movable groove is fixedly connected to the support wheel frame. A rack is fixedly connected to the side of the sliding block near the guide rod. The rack meshes with the climbing component, and the climbing component is positioned below the rack.

[0007] Preferably, the climbing assembly includes a gear shaft, a threaded sleeve, a second cylinder, a climbing wheel frame, and a limiting component. The end of the gear shaft is connected to the main body of the cruise vehicle via a bearing, and the end of the threaded sleeve is connected to the second cylinder via a bearing. The gear shaft and the threaded sleeve are connected by a belt, and the two ends of the threaded sleeve are engaged with the climbing wheel frame. The climbing wheel frame is movably connected to the limiting component.

[0008] Preferably, a transmission gear that meshes with a rack is fixedly connected to the gear shaft, and pulleys are symmetrically arranged on the gear shafts on both sides of the transmission gear, with the pulleys sleeved with a belt.

[0009] Preferably, the cruise trolley body has a first elongated groove on the side wall near the lower part of the movable slot, the first elongated groove is movably connected to the end of the threaded sleeve, and the second cylinder is disposed on the side wall of the first elongated groove.

[0010] Preferably, one end of the first long waist groove is connected to a second long waist groove, a climbing wheel frame runs through the second long waist groove, and a wheel groove is connected to the side of the second long waist groove away from the first long waist groove.

[0011] Preferably, the climbing wheel frame includes a threaded rod, a wheel drive source, and a climbing wheel body. The threaded rod engages with a threaded sleeve. One end of the threaded rod is provided with a wheel drive source. The output end of the wheel drive source is connected to the climbing wheel body. The wheel drive source and the climbing wheel body are placed in the wheel groove.

[0012] Preferably, a limiting groove is provided on the threaded rod, and the limiting groove is movably connected to the limiting component.

[0013] Preferably, the limiting member includes a supporting spring and a limiting ball, with the upper end of the supporting spring fixedly connected to the top of the second elongated groove and the lower end of the supporting spring fixedly connected to the limiting ball.

[0014] Preferably, a slot is provided on one side of the cargo frame, a baffle is inserted into the slot, one end of the cargo frame near the baffle is hinged to the main body of the cruise vehicle, the other end of the cargo frame is hinged to the lifting plate, and a level is provided on the cargo frame.

[0015] Another technical problem to be solved by the present invention is to provide a method for using a cruiser that facilitates climbing slopes while preventing items from tipping over, comprising the following steps:

[0016] S1: When the cruise trolley body is moving, it detects that it needs to climb a slope. The second cylinder drives the threaded sleeve to move down, and the two climbing wheel bodies contact the ground. The belt is tightened, the wheel drive source is turned on, and the climbing wheel bodies are controlled to work, providing power for the cruise trolley body to climb the slope.

[0017] S2: When the front wheels of the cruise trolley move to the slope, the entire cruise trolley body tilts. The level on the cargo box detects that it is not level, the second cylinder automatically opens, pushes the sliding block to move, and drives the lifting plate to push the cargo box away from the cruise trolley body, ensuring that the cargo box is level and thus preventing the items in the cargo box from tipping over.

[0018] S3: The sliding block simultaneously drives the rack to move, the transmission gear to rotate, the gear shaft to rotate, and through the pulley and belt to drive the threaded sleeve to rotate. The climbing wheel frame moves in the same direction at the same time, the distance between the climbing wheel bodies increases, and the support wheel frame, under the action of the guide rod, pulls a certain distance away from the cruise trolley body, which plays a supporting role when the cruise trolley body climbs the slope.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention, by setting up a climbing component, can use the climbing wheel body to provide power to the cruise trolley body when climbing a slope, increasing friction and preventing slippage. When climbing is not needed, the climbing wheel body can be retracted into the wheel groove and lifted off the ground, reducing the resistance when the cruise trolley body moves in a plane. The cargo frame can rotate, thereby satisfying the adjustable angle between the cargo frame and the cruise trolley body. When the cruise trolley body is climbing a slope, the cargo frame remains horizontal to prevent the items from tipping over.

[0021] 2. In this invention, the carrying frame is pushed upward by the lifting plate, and the sliding block controls the movement of the lifting plate. While the lifting plate rotates, the support wheel frame is separated from the main body of the cruise vehicle by a certain distance, which provides support for the main body of the cruise vehicle when it climbs the slope. The rack drives the gear shaft to rotate, controlling the climbing wheel frame to move in opposite directions at the same time. According to the slope height, the distance between the climbing wheel bodies is automatically adjusted to increase the support area of ​​the chassis of the cruise vehicle, lower the overall center of gravity, and improve the stability of the cruise vehicle body.

[0022] 3. The present invention provides space for the up-and-down movement of the climbing wheel frame through the first and second long waist grooves, and changes the state of the belt. It can be selected whether to control the distance adjustment of the climbing wheel frame. It is mainly used so that when the goods are transported to the designated point, the goods can be removed by tilting without adjusting the climbing wheel frame. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] To address the issue of existing technologies using prefabricated racks to assist vehicle movement (as described in this patent), which require specially designed prefabricated racks increasing installation costs, and the need for precise alignment with the prefabricated racks during the cruise vehicle's hill-climbing process, please refer to [link / reference needed]. Figures 1-7 This embodiment provides the following technical solution:

[0033] A cruise trolley that facilitates climbing slopes while preventing items from tipping over includes a cruise trolley body 1 and a cargo frame 2. One end of the cruise trolley body 1 is hinged to the cargo frame 2. The upper surface of the cruise trolley body 1 has a movable groove 11. A lifting component 3 and a climbing component 4 are arranged in the movable groove 11. The lifting component 3 includes a first cylinder 31, a sliding block 32, a lifting plate 33, a guide rod 34, and a support wheel frame 35. The output end of the first cylinder 31 is fixedly connected to the sliding block 32. The first cylinder 31 is embedded in the cruise trolley body 1. When the first cylinder 31 is working, it drives the sliding block 32 to move horizontally within the movable groove 11.

[0034] A lifting plate 33 is movably connected to the sliding block 32. One end of the lifting plate 33 is hinged to the carrying frame 2. When the sliding block 32 moves, it drives one end of the lifting plate 33 to move to a different position, and the other end of the lifting plate 33 moves upward to adapt to the change in position of the lifting plate 33, thereby controlling the tilt of the carrying frame 2. The slot of the movable groove 11 matches the lifting plate 33. When the lifting plate 33 is not in use, it engages with the movable groove 11, which does not affect the installation of the carrying frame 2.

[0035] A guide rod 34 is symmetrically arranged on one side of the sliding block 32. The guide rod 34 passes through the movable groove 11, and a support wheel frame 35 is fixedly connected to the end of the guide rod 34 outside the movable groove 11. The guide rod 34 moves with the sliding block 32 and restricts the movement direction of the sliding block 32. At the same time, when the guide rod 34 moves, it drives the support wheel frame 35 to move away from the cruise vehicle body 1, and pulls a certain distance away from the cruise vehicle body 1, so as to provide support for the cruise vehicle body 1 when climbing. The support wheel frame 35 includes a positioning sleeve, a second-stage sliding shaft and a driven wheel. The second-stage sliding shaft is movably connected to the positioning sleeve, and the driven wheel is movably connected to the second-stage sliding shaft. The second-stage sliding shaft controls the driven wheel to move up or down until the driven wheel contacts the ground, so as to provide support.

[0036] A rack 341 is fixedly connected to the side of the sliding block 32 near the guide rod 34. The rack 341 meshes with the climbing component 4. The climbing component 4 is positioned below the rack 341. When the sliding block 32 moves, it synchronously drives the rack 341 to move. The end of the rack 341 away from the sliding block 32 overlaps with the end of the movable groove 11. The movable groove 11 limits the movement of the rack 341.

[0037] The climbing assembly 4 includes a gear shaft 41, a threaded sleeve 42, a second cylinder 43, a climbing wheel frame 44, and a limiting member 45. The end of the gear shaft 41 is connected to the main body 1 of the cruise vehicle via a bearing, and the end of the threaded sleeve 42 is connected to the second cylinder 43 via a bearing. The gear shaft 41 and the threaded sleeve 42 are connected by a belt 411. The gear shaft 41 and the threaded sleeve 42 can rotate. The threads inside the threaded sleeve 42 are in opposite directions. The two ends of the threaded sleeve 42 are engaged with the climbing wheel frame 44. When the gear shaft 41 drives the threaded sleeve 42 to rotate, the climbing wheel frame 44 on the threaded sleeve 42 moves in opposite directions at the same time. The climbing wheel frame 44 is movably connected to the limiting member 45. The limiting member 45 restricts the climbing wheel frame 44 to prevent it from rotating, so that the climbing wheel frame 44 can only extend in and out in a set direction.

[0038] A transmission gear 412 that meshes with a rack 341 is fixedly connected to the gear shaft 41. Pulleys are symmetrically arranged on the gear shaft 41 on both sides of the transmission gear 41, and the pulleys are sleeved with the belt 411.

[0039] When the rack 341 moves, it drives the transmission gear 412 to rotate, and the gear shaft 41 rotates, which in turn drives the threaded sleeve 42 to rotate through the pulley and belt 411.

[0040] The cruise vehicle body 1 has a first long waist groove 12 on the side wall below the movable slot 11. The first long waist groove 12 is movably connected to the end of the threaded sleeve 42, and the second cylinder 43 is disposed on the side wall of the first long waist groove 12.

[0041] Specifically, the second cylinder 43 is fixed in position. The second cylinder 43 drives the threaded sleeve 42 to move up or down. The threaded sleeve 42 has a belt groove that matches the belt 411. When the threaded sleeve 42 is engaged with the upper end of the first long waist groove 12, the climbing wheel frame 44 is not in contact with the ground, the belt 411 is in a slack state, and the gear shaft 41 rotates without driving the threaded sleeve 42 to rotate. When the threaded sleeve 42 is pushed by the second cylinder 43 to engage with the lower end of the first long waist groove 12, the climbing wheel frame 44 is in contact with the ground, the belt 411 is in a taut state, and the rotation of the gear shaft 41 drives the threaded sleeve 42 to rotate synchronously.

[0042] One end of the first long waist groove 12 is connected to the second long waist groove 13, and the climbing wheel frame 44 passes through the second long waist groove 13. The side of the second long waist groove 13 away from the first long waist groove 12 is connected to the wheel groove 14.

[0043] Specifically, the second long waist groove 13 provides space for the climbing wheel frame 44 to move up and down.

[0044] The climbing wheel frame 44 includes a threaded rod 441, a wheel drive source 442, and a climbing wheel body 443. The threaded rod 441 meshes with a threaded sleeve 42. One end of the threaded rod 441 is provided with a wheel drive source 442. The output end of the wheel drive source 442 is connected to the climbing wheel body 443. The wheel drive source 442 and the climbing wheel body 443 are placed in the wheel groove 14.

[0045] Specifically, when the threaded rod 441 rotates with the threaded sleeve 42, it drives the wheel drive source 442 and the climbing wheel body 443 to extend into or out of the wheel groove 14. The wheel drive source 442 independently drives and controls the rotation of the climbing wheel body 443. When both climbing wheel bodies 443 move out of the wheel groove 14, the climbing wheel body 443 supports the cruise vehicle body 1, increases the chassis support area of ​​the cruise vehicle body 1, lowers the overall center of gravity, and improves the stability of the cruise vehicle body 1. At the same time, the climbing wheel body 443 uses a special climbing tire with high resistance, which can increase friction, provide power for the cruise vehicle body 1, and prevent slippage.

[0046] A limiting groove 4411 is provided on the threaded rod 441, and the limiting groove 4411 is movably connected to the limiting member 45.

[0047] Under the action of the limiting member 45, the threaded rod 441 cannot rotate.

[0048] The limiting member 45 includes a support spring 451 and a limiting ball 452. The upper end of the support spring 451 is fixedly connected to the top of the second elongated groove 13, and the lower end of the support spring 451 is fixedly connected to the limiting ball 452.

[0049] Specifically, when the threaded rod 441 moves up or down with the threaded sleeve 42, the support spring 451 extends and retracts accordingly to ensure that the limiting ball 452 is always within the limiting groove 4411, thus limiting the threaded rod 441.

[0050] A slot 21 is provided on one side of the cargo frame 2, and a baffle 22 is inserted into the slot 21. One end of the cargo frame 2 near the baffle 22 is hinged to the cruise vehicle body 1, and the other end of the cargo frame 2 is hinged to the lifting plate 33. A level is provided on the cargo frame 2.

[0051] Specifically, the baffle 22 can be installed through the slot 21, so that the carrying frame 2 forms a carrying space with four sides covered. When the carrying frame 2 is tilted, the baffle 22 can be removed and the items can be poured out directly.

[0052] To better demonstrate the operation of a cruiser that facilitates climbing slopes while preventing items from tipping over, this embodiment presents a method for using such a cruiser, including the following steps:

[0053] Step 1: When the cruise vehicle body 1 is moving, it detects that it needs to climb a slope. The second cylinder 43 drives the threaded sleeve 42 to move down, and the two climbing wheel bodies 443 contact the ground. The belt 411 is tightened, the wheel drive source 442 is turned on, and controls the climbing wheel bodies 443 to work, providing power for the cruise vehicle body 1 to climb the slope.

[0054] Step 2: When the front wheels of the cruise trolley body 1 move to the slope, the cruise trolley body 1 tilts as a whole. The level on the cargo box 2 detects that it is not level. The second cylinder 43 is automatically activated, pushing the sliding block 32 to move and driving the lifting plate 33 to push the cargo box 2 to separate from the cruise trolley body 1, ensuring that the cargo box 2 is level, thereby preventing the items in the cargo box 2 from tipping over.

[0055] Step 3: The sliding block 32 simultaneously drives the rack 341 to move, the transmission gear 412 rotates, the gear shaft 41 rotates, and the threaded sleeve 42 rotates through the pulley and belt 411. The climbing wheel frame 44 moves in the same direction at the same time, and the distance between the climbing wheel body 443 increases. Under the action of the guide rod 34, the support wheel frame 35 is pulled away from the cruise trolley body 1 by a certain distance, which plays a supporting role when the cruise trolley body 1 climbs the slope.

[0056] In summary, this invention presents a cruiser that facilitates climbing while preventing items from tipping over, and its usage method. By incorporating a climbing component 4, the climbing wheel body 443 provides power to the cruiser body 1 during climbing, increasing friction and preventing slippage. When climbing is not required, the climbing wheel body 443 is retracted into the wheel groove 14 and lifted off the ground, reducing resistance during planar movement of the cruiser body 1. The cargo frame 2 can rotate, thus allowing for adjustable angle between the cargo frame 2 and the cruiser body 1. When the cruiser body 1 is climbing, the cargo frame 2 remains horizontal, preventing items from tipping over. The cargo frame 2 is pushed upward by the lifting plate 33, and the sliding block 32 controls the movement of the lifting plate 33. While the lifting plate 33 rotates, it also supports... The wheel frame 35 is spaced a certain distance from the cruise trolley body 1, providing support for the cruise trolley body 1 when climbing. The rack 341 drives the gear shaft 41 to rotate, controlling the climbing wheel frames 44 to move simultaneously in opposite directions. According to the slope height, the distance between the climbing wheel frames 443 is automatically adjusted to increase the chassis support area of ​​the cruise trolley body 1, lower the overall center of gravity, and improve the stability of the cruise trolley body 1. The first long waist groove 12 and the second long waist groove 13 provide space for the climbing wheel frames 44 to move up and down. By changing the state of the belt 411, it is possible to choose whether to control the distance adjustment of the climbing wheel frames 44. This is mainly used so that when the goods are transported to the designated point, the goods can be unloaded by tilting without adjusting the climbing wheel frames 44.
