Description

Technical Field

[0001] This invention relates to the field of logistics and distribution technology, and more specifically to an intelligent logistics and distribution vehicle. Background Technology

[0002] In the logistics sector, intelligent logistics vehicles have been widely used in office buildings, communities, property management companies, and large supermarkets to save labor and improve efficiency.

[0003] Intelligent logistics vehicles are based on traditional transport vehicles, with the addition of route guidance functions. They use transport vehicles to carry goods and, combined with route guidance, achieve logistics distribution from origin to destination.

[0004] A search revealed Chinese patent publication number CN215709453U, which discloses a logistics vehicle and a logistics transportation system, including a vehicle body, a collision avoidance mechanism, and a controller. At least one of the front and rear ends of the vehicle body is equipped with a collision avoidance mechanism, which includes a sensor and a movable collision avoidance component. When the collision avoidance component moves to a trigger position, it triggers the sensor. The sensor can communicate with the controller, and when the sensor is triggered, the controller stops the logistics vehicle.

[0005] The aforementioned patent has the following shortcomings: when transporting goods, uneven roads and centrifugal forces on the goods during turns can cause a force parallel to the load-bearing surface between the goods and the trolley, thus posing a risk of slippage.

[0006] Therefore, how to provide an intelligent logistics delivery vehicle that can overcome the above problems is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] In view of this, the present invention provides an intelligent logistics delivery vehicle.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An intelligent logistics delivery vehicle includes a mobile chassis, a platform connected to the mobile chassis via an adaptive balance adjustment mechanism, and a cargo box placed on top of the platform for storing goods. Electromagnets A and B, and a slider are disposed below the platform. The slider is longitudinally slidably engaged with both sides of the mobile chassis, and a connecting rod is rotatably engaged at the top of the slider, with the other side of the connecting rod rotatably connected to the bottom of the platform. Electromagnet B is fixedly installed at the bottom of the slider, and electromagnet A is fixedly installed on the inner bottom of the mobile chassis. The magnetic poles on opposite sides of iron A and electromagnet B are the same; a sensing component is also provided below the platform. The sensing component includes insulating plates fixed to both sides of the walking chassis and two sets of rods fixed to opposite sides of the insulating plates. The two sets of rods are electrically connected to the two sets of electromagnets A and B, respectively. The rods include a first resistor rod, a second resistor rod, and a sliding terminal that is slidably engaged and electrically connected to the outside of the first and second resistor rods. The first resistor rod, the second resistor rod, the sliding terminal, electromagnet A, and electromagnet B are connected in series in the same circuit, and the circuit has a built-in power supply.

[0010] As can be seen from the above technical solution, compared with the prior art, the present invention discloses an intelligent logistics distribution and transportation vehicle. By setting an adaptive balance adjustment mechanism, on the one hand, when the device travels on uneven roads, it can automatically adjust the angle of the platform according to the tilt direction and angle of the device; on the other hand, when the device turns, it can automatically adjust the angle of the platform according to the direction of centrifugal force, so that the force between the platform and the cargo box always remains perpendicular to the plane of the platform, preventing the goods from slipping. The platform angle adjustment components are set as electromagnets A and B, and the tilt and turning sensing components are set as resistor rod one, resistor rod two, and sliding terminal in combination, thus eliminating the need for traditional electronic control methods combining sensors and host computers, reducing costs and increasing response speed. By utilizing the characteristics of electromagnetic induction and resistivity, and using the magnitude of current as the signal transmission medium, on the one hand, electromagnets A and B can work together to play a shock absorption role during normal driving; on the other hand, the shock absorption stiffness and the height of the platform can be controlled by controlling the voltage of the power supply.

[0011] Preferably, the same insulating counterweight is fixed on one side of each of the two sliding terminals, and both sides of the insulating counterweight are connected to the opposite side of the insulating plate by springs. In its natural state, the insulating counterweight is located at the left and right symmetrical center of the first resistance rod.

[0012] Furthermore, an anti-slip pad is fixedly installed on the top of the platform, and a magnetic pad is fixedly embedded inside the platform.

[0013] Based on the aforementioned scheme: the walking chassis includes a chassis frame, a steering wheel located in front of the chassis frame, a drive wheel located behind the chassis frame, a steering mechanism mounted on the chassis frame for driving the steering wheel to turn, and a drive mechanism for driving the motor to rotate.

[0014] A preferred embodiment of the aforementioned scheme is as follows: the steering mechanism includes a telescopic device fixedly installed on the chassis frame, a steering tie rod slidably connected to the chassis frame, and a wheel frame rotatably engaged with the steering wheel. The wheel frame is rotatably engaged with the side wall of the chassis frame via a movable shaft. The wheel frame has an oblong hole, and a limiting pin is inserted into the oblong hole. The steering tie rod is movably limited and engaged with the inner side of the wheel frame via the limiting pin.

[0015] As a further aspect of the present invention: the telescopic end of the telescopic device is fixedly installed on the side wall of the steering tie rod.

[0016] Meanwhile, the drive mechanism includes a drive motor and an input shaft. The drive motor is fixedly installed on the side wall of the chassis frame, and the input shaft is rotatably connected to the inner wall of the chassis frame. The output shaft of the drive motor is driven to the input shaft through a speed change assembly, and the input shaft is driven to the drive wheel through a transfer assembly.

[0017] As a preferred embodiment of the present invention: the transfer assembly includes an axle and an input frame. The drive wheel is rotatably connected to both sides of the chassis frame via the axle. A conical wheel A is fixedly installed on the outer wall of the axle. Two conical wheels B mesh with the inner sides of the two oppositely arranged conical wheels A. The conical wheels B are rotatably connected to the input frame. The input frame is rotatably connected to the outer wall of one of the axles. A conical wheel B is fixedly installed on the outer wall of the input frame. A conical wheel A meshes with the outer wall of the conical wheel B. The conical wheel A is fixedly installed on the outer wall of the input shaft.

[0018] Meanwhile, the transmission assembly includes an input pinion and an input gear fixedly connected to the output shaft of the drive motor, and an output gear and an output pinion fixedly connected to the outer wall of the input shaft. The transmission assembly also includes a switching gear slidably connected to the chassis frame, with transition gear A and transition gear B rotatably connected to both sides of the switching gear.

[0019] As a more preferred embodiment of the present invention: the input large gear, the transition gear A, and the output small gear can be meshed and driven in sequence, and the input small gear, the transition gear B, and the output large gear can be meshed and driven in sequence, and the meshing of the input large gear, the transition gear A, and the output small gear is not performed simultaneously with the meshing of the input small gear, the transition gear B, and the output large gear.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. By setting an adaptive balance adjustment mechanism, the present invention can automatically adjust the angle of the platform according to the tilt direction and angle of the device when the device is on an uneven road surface. On the other hand, when the device turns, it can automatically adjust the angle of the platform according to the direction of centrifugal force, so that the force between the platform and the cargo box always remains perpendicular to the plane of the platform, preventing the goods from slipping.

[0022] 2. This invention sets the platform angle adjustment components as electromagnets A and B, and the tilt and steering sensing components as resistor rod one, resistor rod two, and sliding terminal in combination. This eliminates the need for traditional electronic control methods that combine sensors and host computers, reducing costs and increasing response speed.

[0023] 3. This invention utilizes the characteristics of electromagnetic induction and resistivity, using the magnitude of the current as the signal transmission medium. On the one hand, it enables electromagnets A and B to work together to dampen vibrations during normal operation. On the other hand, it also allows control over the damping stiffness and the height of the platform by controlling the voltage of the power supply.

[0024] 4. This invention utilizes a "sliding rheostat" type control resistor consisting of a first resistor rod, a second resistor rod, and a sliding terminal. Compared to the traditional structure, the slider, i.e. the sliding terminal, of this invention only serves a conductive function and does not require connecting wires. This facilitates wire routing and prevents tangling, while also preventing the connection of wires from affecting the position of the sliding terminal, thus increasing the sensing accuracy.

[0025] 5. By setting up a speed-changing component and adopting a dual-drive chain design, this invention not only ensures the speed-up effect in straight-line mode, increasing delivery efficiency, but also ensures the speed-down function in turning mode, thereby increasing the stability of the device.

[0026] 6. By setting an input shaft and adopting an indirect transmission form, the present invention enables two drive wheels to simultaneously have driving force and different driving speeds. Furthermore, the speed difference can be steplessly adaptively adjusted according to the actual path of the drive wheels. This ensures that the speed difference between the two drive wheels is automatically compensated during steering, preventing relative slippage between the drive wheels and the ground, thus preventing sideslip and fishtailing and increasing driving stability.

[0027] 7. By setting up a second linkage, the present invention links steering and transmission. By utilizing the relationship between driving state and the position of steering tie rod, and combining the position change of steering tie rod, the transmission function is driven, thereby increasing the linkage of the device. Moreover, the whole process does not require manual or electronic control intervention, which increases convenience and response speed. Attached Figure Description

Detailed Implementation

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below. 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.

[0042] Example 1:

[0043] This invention specifically discloses an intelligent logistics delivery vehicle, such as... Figure 1-5 As shown, it includes a mobile chassis 1, a platform 3 connected above the mobile chassis 1 via an adaptive balance adjustment mechanism 2, and a cargo box 4 placed on top of the platform 3 for storing goods.

[0044] Below the platform 3 are electromagnets A6 and B7 and slider 8. Slider 8 slides longitudinally on both sides of the walking chassis 1, and the top of slider 8 is rotatably connected to connecting rod 9. The other side of connecting rod 9 is rotatably connected to the bottom of the platform 3.

[0045] Electromagnet B7 is fixed to the bottom of slider 8 by bolts, and electromagnet A6 is fixed to the inner bottom of the walking chassis 1 by bolts. Electromagnet A6 and electromagnet B7 have the same magnetic poles on opposite sides.

[0046] A sensing component 5 is also provided below the platform 3. The sensing component 5 includes an insulating plate 10 fixed to both sides of the walking chassis 1 and two sets of rods 11 fixed to opposite sides of the insulating plate 10. The two sets of rods 11 are electrically connected to two sets of electromagnets A6 and B7, respectively.

[0047] The rod 11 includes a first resistor 12, a second resistor 13, and a sliding terminal 14 that is slidably engaged and electrically connected to the outside of the first resistor 12 and the second resistor 13. The first resistor 12, the second resistor 13, the sliding terminal 14, the electromagnet A6, and the electromagnet B7 are connected in series in the same circuit, and the circuit has a built-in power supply 17.

[0048] The same insulating counterweight 15 is fixed on the opposite side of the two sliding terminals 14. Both sides of the insulating counterweight 15 are connected to the opposite side of the insulating plate 10 by springs 16, and the insulating counterweight 15 in its natural state is located at the left and right symmetrical center of the resistance rod 12.

[0049] When in normal driving condition, the walking chassis 1 is in a horizontal state, and the sliding terminal 14 is located at the left and right symmetrical center of the device. The current of electromagnets A6 and B7 on the left and right sides is the same, so that the height of the slider 8 is the same, and the platform 3 is also in a horizontal state.

[0050] When on an uneven, sloping surface, the tilting effect of this device is opposite on both sides, therefore, this is based on... Figure 4 Taking the device tilting to the left as an example, since the insulating counterweight 15 is also tilted, it slides to the left under the action of gravity, thereby changing the position of the sliding terminal 14 in conjunction with the first resistor 12 and the second resistor 13. At this time, in the left circuit, the path of current flowing through the first resistor 12 and the second resistor 13 is reduced, the resistance decreases, and the current increases. In the right circuit, the path of current flowing through the first resistor 12 and the second resistor 13 is increased, the resistance increases, and the current decreases. This causes the repulsive force between the electromagnet A6 and the electromagnet B7 on the left to increase, and the slider 8 to move upward. The repulsive force between the electromagnet A6 and the electromagnet B7 on the right to decrease, and the slider 8 to move downward. Through the change in the height of the sliders 8 on both sides, combined with the connecting action of the first connecting rod 9, the plane of the platform 3 tilts to the right, thereby compensating for the tilt angle of the entire device and allowing the platform 3 to remain horizontal.

[0051] When in a turning state, the insulating counterweight 15 is moved to one side by centrifugal force. Based on the above analysis of the tilting process, it can be seen that the platform 3 will tilt to the other side of the moving direction. Thus, through the tilting action of the platform 3, the resultant force of gravity and centrifugal force on the cargo box 4 and the cargo is perpendicular to the plane of the platform 3. This makes the total force of the platform 3 on the cargo box 4 perpendicular to the plane of the platform 3, thereby preventing relative sliding between the platform 3 and the cargo box 4 and ensuring the stability of the cargo.

[0052] This device is equipped with an adaptive balance adjustment mechanism 2. On the one hand, when the device is on an uneven road surface, it can automatically adjust the angle of the platform 3 according to the tilt direction and angle of the device. On the other hand, when the device turns, it can automatically adjust the angle of the platform 3 according to the direction of centrifugal force, so that the force between the platform 3 and the cargo box 4 always remains perpendicular to the plane of the platform 3, preventing the goods from slipping.

[0053] This device uses electromagnets A6 and B7 to adjust the angle of the platform 3, and resistor rod 12, resistor rod 13, and sliding terminal 14 to sense tilt and turn. This eliminates the need for traditional electronic control methods that combine sensors and host computers, reducing costs and increasing response speed.

[0054] This device utilizes the characteristics of electromagnetic induction and resistivity, using the magnitude of current as the signal transmission medium. On the one hand, it allows electromagnets A6 and B7 to work together to dampen vibrations during normal operation. On the other hand, it can also control the damping stiffness and the height of the platform 3 by controlling the voltage of the power supply 17.

[0055] In addition, although this device controls the resistance by using a "sliding rheostat" with resistor rod 12, resistor rod 13 and sliding terminal 14, compared with the traditional structure, the slider of this invention, that is, the sliding terminal 14, only serves as a conductor and does not need to be connected with wires. On the one hand, it facilitates the wiring of wires and prevents tangling, and on the other hand, it prevents the connection of wires from affecting the position of the sliding terminal 14, thus increasing the sensing accuracy.

[0056] To further address stability issues; such as... Figure 5 As shown, the top of the platform 3 is fixed with an anti-slip pad 18 by bolts, and a magnetic pad 19 is fixedly embedded inside the platform 3.

[0057] The anti-slip effect can be further enhanced by setting up the anti-slip pad 18 and the magnetic pad 19.

[0058] In this embodiment, the goods to be transported can be placed in the cargo box 4, and the cargo box 4 can be placed on top of the platform 3. The walking chassis 1 can be controlled to move, and only the goods can be transported.

[0059] Example 2:

[0060] A smart logistics delivery vehicle, such as Figure 6-10 As shown, in order to solve the problem of walking safety, this embodiment makes the following improvements based on embodiment 1: the walking chassis 1 includes a chassis frame 20, a steering wheel 21 disposed in front of the chassis frame 20, a drive wheel 27 disposed behind the chassis frame 20, a steering mechanism 22 for driving the steering wheel 21 to turn, and a drive mechanism for driving the motor 23 to rotate.

[0061] To solve the steering problem, such as Figure 7 As shown: The steering mechanism 22 includes a telescopic device 32 fixed to the chassis frame 20 by bolts, a steering tie rod 33 slidably connected to the chassis frame 20, and a wheel frame 29 rotatably engaged with the steering wheel 21. The wheel frame 29 is rotatably engaged with the side wall of the chassis frame 20 through a movable shaft 28. The inner wall of the wheel frame 29 is provided with a waist-shaped hole 30, and a limiting pin 31 is inserted into the waist-shaped hole 30. The steering tie rod 33 is movably limited and engaged with the inner side of the wheel frame 29 through the limiting pin 31.

[0062] The telescopic end of the telescopic device 32 is fixed to the side wall of the steering tie rod 33 by bolts.

[0063] When the telescopic device 32 extends or retracts, it can drive the steering tie rod 33 to slide, thereby driving the wheel frame 29 to rotate through the movable limit pin 31 and the waist-shaped hole 30, which in turn drives the steering wheel 21 to rotate, thus achieving steering.

[0064] To solve driver issues, such as Figure 6 , 8 As shown in Figure 9, the drive mechanism includes a drive motor 23 and an input shaft 25. The drive motor 23 is fixed to the side wall of the chassis frame 20 by bolts. The input shaft 25 is rotatably connected to the inner wall of the chassis frame 20. The output shaft of the drive motor 23 is connected to the input shaft 25 through a speed change assembly 24. The input shaft 25 is connected to the drive wheel 27 through a transfer assembly 26.

[0065] The transfer assembly 26 includes an axle 35 and an input frame 39. The drive wheel 27 is rotatably connected to both sides of the chassis frame 20 via the axle 35. The outer wall of the axle 35 is connected to a second conical wheel A37 via a key. Two second conical wheels B38 mesh with the inner sides of opposite second conical wheels A37. The second conical wheel B38 is rotatably connected to the input frame 39. The input frame 39 is rotatably connected to the outer wall of one of the axles 35. A first conical wheel B36 is welded to the outer wall of the input frame 39. A first conical wheel A34 meshes with the outer wall of the first conical wheel B36. The first conical wheel A34 is connected to the outer wall of the input shaft 25 via a key.

[0066] The speed change assembly 24 includes an input pinion 40 and an input gear 42 connected to the output shaft of the drive motor 23 by a key, and an output gear 46 and an output pinion 45 connected to the outer wall of the input shaft 25 by a key.

[0067] The transmission assembly 24 also includes a switching gear 41 that is slidably connected to the chassis frame 20, and a transition gear A43 and a transition gear B44 are rotatably connected to both sides of the switching gear 41.

[0068] The input large gear 42, the transition gear A43, and the output small gear 45 can mesh and drive in sequence. The input small gear 40, the transition gear B44, and the output large gear 46 can mesh and drive in sequence. The meshing of the input large gear 42, the transition gear A43, and the output small gear 45 does not occur simultaneously with the meshing of the input small gear 40, the transition gear B44, and the output large gear 46. That is, the two are staggered.

[0069] When in straight-line mode, the input large gear 42, the transition gear A43, and the output small gear 45 are engaged. The drive motor 23 drives the input large gear 42 to rotate, which in turn drives the output small gear 45 to rotate via the transition gear A43, thereby driving the input shaft 25 to rotate. At this time, the speed of the input shaft 25 is greater than the speed of the drive motor 23. When in turning mode, the switching bracket 41 slides, and the input small gear 40, the transition gear B44, and the output large gear 46 are engaged. The drive motor 23 drives the input small gear 40 to rotate, which in turn drives the output small gear 45 to rotate via the transition gear A43. At this time, the speed of the input shaft 25 is less than the speed of the drive motor 23.

[0070] When the input shaft 25 rotates, it drives the input frame 39 to rotate through the meshing of conical wheel A34 and conical wheel B36. In turn, the meshing of conical wheel B38 and conical wheel A37 drives the wheel axle 35 and the drive wheel 27 to rotate, thus achieving walking drive. When in the turning state, since conical wheel A37 is driven by the meshing of conical wheel B38 and conical wheel B38 can rotate relative to the input frame 39, the two drive wheels 27 can simultaneously have driving force and different driving speeds. The speed difference can be steplessly adaptively adjusted according to the path of the drive wheel 27.

[0071] This device, by incorporating a speed-changing assembly 24 and employing a dual-drive chain design, ensures both increased speed during straight-line travel to enhance delivery efficiency and reduced speed during turns, thereby increasing the device's stability.

[0072] In addition, by setting an input shaft 25, which adopts an indirect transmission form, this device enables the two drive wheels 27 to have driving force at the same time and different driving speeds. The speed difference can be steplessly adaptively adjusted according to the actual path of the drive wheels 27, thereby ensuring that the speed difference between the two drive wheels 27 is automatically compensated when turning, preventing the drive wheels 27 from sliding relative to the ground, thus preventing sideslip and tail-wagging, and increasing the stability of walking.

[0073] To solve the problem of automatic adjustment, such as Figure 10As shown, the inner side of the switching bracket 41 is rotatably connected to the connecting rod 48 via the second movable shaft 47, and the other end of the connecting rod 48 is rotatably connected to both sides of the steering tie rod 33 via the third movable shaft 49.

[0074] When the device is in a straight-line state, the second connecting rod 48 and the steering tie rod 33 are perpendicular to each other.

[0075] When in a straight-line state, the second linkage 48 is perpendicular to the steering tie rod 33, and the switching bracket 41 is located at the furthest distance from the steering tie rod 33. This allows the transition gear A43 to mesh between the input large gear 42 and the output small gear 45, ensuring acceleration. When in a turning state, that is, when the steering wheel 21 deflects relative to the chassis frame 20 by a certain angle, the steering tie rod 33 slides left / right. This causes the second linkage 48 to pull the switching bracket 41 forward, allowing the transition gear B44 to mesh between the input small gear 40 and the output large gear 46, ensuring deceleration and turning.

[0076] This device uses a second linkage 48 to link steering and transmission. By using the driving state and the position of the steering tie rod 33, the transmission function is driven by the change in the position of the steering tie rod 33. This increases the linkage of the device, and the whole process does not require manual or electronic intervention, which increases convenience and response speed.

[0077] In this embodiment, when in a straight-ahead state, the connecting rod 48 is perpendicular to the steering lever 33, and the shift lever 41 is located at the furthest point from the steering lever 33. This allows the transition gear A43 to mesh between the input large gear 42 and the output small gear 45. At this time, the input large gear 42, transition gear A43, and output small gear 45 are in a meshed state. The drive motor 23 drives the input large gear 42 to rotate, which in turn drives the output small gear 45 to rotate via the transition gear A43, thereby driving the input shaft 25 to rotate. At this time, the speed of the input shaft 25 is greater than the speed of the drive motor 23. When in a turning state, the shift lever 41 slides, and the input small gear 40, transition gear B44, and output large gear 46 are in a meshed state. The drive motor 23 drives the input small gear 40 to rotate, which in turn drives the output small gear 45 to rotate via the transition gear A43. At this time, the speed of the input shaft 25 is less than the speed of the drive motor 23. When in a turning state, the steering lever 33 shifts to the left. Slide the lever to the right, thereby pulling the switching bracket 41 forward via the second linkage 48. This causes the transition gear B44 to mesh between the input pinion 40 and the output gear 46. The drive motor 23 drives the input pinion 40 to rotate, and the transition gear A43 drives the output pinion 45 to rotate. At this time, the speed of the input shaft 25 is less than the speed of the drive motor 23. When the input shaft 25 rotates, it can drive the input frame 39 to rotate through the meshing of the first conical wheel A34 and the first conical wheel B36. This, in turn, drives the wheel axle 35 and the drive wheel 27 to rotate through the meshing of the second conical wheel B38 and the second conical wheel A37, thus achieving walking drive. When in the turning state, since the second conical wheel A37 is driven by the meshing of the second conical wheel B38 and the second conical wheel B38 can rotate relative to the input frame 39, the two drive wheels 27 can simultaneously have driving force and different driving speeds. This speed difference can be continuously and adaptively adjusted according to the actual path of the drive wheel 27.
