A lightweight four-way vehicle that prevents deviation

Abstract

The present invention provides a lightweight, anti-deviating four-way vehicle. By optimizing the overall mounting of the vehicle's accessories, the relevant sensing controls, switches, and circuit boxes are designed to be placed on the vehicle's periphery for easy maintenance and free up space in the center of the vehicle for easy placement. The vehicle's interior is then divided into four evenly spaced areas. The rational distribution of accessory mounting locations within these areas ensures a 50%:50 weight distribution across the vehicle's entirety. This prevents the vehicle from deflecting due to uneven weight, causing its route to shift, resulting in inaccurate arrival at designated locations and reduced efficiency. A pressure wheel is provided on the transmission chain to ensure a closer fit between the transmission chain and the rotating shaft, preventing the chain from falling off, causing the vehicle to deflect during travel and causing a deviation in its direction of travel. Two actuators are used to drive the entire vehicle, reducing its weight and achieving lightweight design.

[0001] The invention relates to a four-way vehicle for logistics transportation, in particular to a light-weight four-way vehicle which can prevent deviation. Background Art

[0002] With the rapid development of smart manufacturing within Industry 4.0, smart logistics is becoming increasingly common in the manufacturing industry. Currently, most manufacturers still need to upgrade their existing factories to smart logistics systems. Consequently, the four-way vehicle system is gaining popularity among customers. This system is more suitable for use in older factories, as it is not restricted by space or height. However, the 3D-RGV's design, constrained by the limited space, has many structural inconsistencies. These design flaws have resulted in a significantly higher failure rate compared to other smart logistics equipment.

[0003] The existing four-way vehicle design is constrained by limited space. It requires space for the travel power, lifting drive, lifting power, lifting drive, control system, power module, and detection module. Consequently, the overall design fails to achieve an appropriate weight ratio for the vehicle. The vehicle frequently veers off course during operation, impacting overall operational stability. Summary of the Invention

[0004] To solve the above problems, this technical solution provides a lightweight four-way vehicle that is anti-deviating. This design can effectively solve the problem of the four-way vehicle deviating during operation due to the uneven weight ratio of the vehicle body. The original structure is optimized so that the vehicle body can reach the designated position smoothly and accurately during operation.

[0014] In some embodiments, the frame is provided with a driving device;

[0015] Wherein, the driving device includes a first driver and a second driver;

[0016] Wherein, the driving device further includes a first rotating shaft and a second rotating shaft;

[0017] wherein, the first rotating shaft is rotatably connected to the first driver via a first transmission belt; a first transmission chain and a second transmission chain of the same length are provided at both ends of the first rotating shaft for driving the transverse wheels on both sides, wherein, a plurality of first pressure wheels are provided on the upper end surfaces of the first transmission chain and the second transmission chain, and a plurality of second pressure wheels are provided on the lower end surfaces of the first transmission chain and the second transmission chain for cooperating with the first pressure wheels, and the first pressure wheels and the second pressure wheels apply upper and lower pressures to the first transmission chain and the second transmission chain respectively, so that the first transmission chain and the second transmission chain are in a tensioned state during transmission;

[0035] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] Please refer to Figure 1-9 As shown, a lightweight four-way vehicle with anti-deviation includes a frame 1, and obstacle avoidance sensors 102 for sensing obstacles are provided on the side and end surfaces of the frame 1; positioning sensors 103 for determining the position of the four-way vehicle are provided on the side and end surfaces of the frame 1;

[0037] Among them, the side of the frame 1 is symmetrically provided with a plurality of tension adjusters 104 for adjusting the tension, and one side is provided with a tray sensor 105 for sensing whether the four-way tray is bearing weight;

[0038] The end faces of the frame 1 are each provided with a layer-changing sensor 106 for receiving layer-changing instructions and an antenna 107 for receiving signals;

[0039] The layer change sensor allows the four-way vehicle to go to the designated layer change elevator (equipment) pending position when receiving the layer change command. It can be used as a double check to determine whether the elevator equipment is in place.

[0040] The front end of the vehicle frame 1 is provided with an in-position sensor 108 for sensing whether the four-way vehicle has reached a designated position, a cargo sensor 109 for judging whether there is cargo in front of or behind the four-way vehicle, and a switch button indicator 110;

[0041] The rear end surface of the frame 1 is provided with a wireless receiver 111 for receiving wireless signals and a charging module 112 for four-way charging of the vehicle;

[0042] The interior of the frame is evenly divided into a first area 201, a second area 202, a third area 203, and a fourth area 204;

[0043] The frame 1 has a mass ratio of 1:1 on both sides based on the central axis.

[0044] The layout of the car frame and the surrounding accessories are basically symmetrical, so the weight of the components outside the inner frame is basically equal. The inner frame area is arranged in an evenly distributed weight manner, that is, the interior is divided into four areas.

[0045] The first area mainly houses the hydraulic station, oil block and other components required for the four-way vehicle;

[0046] The second area is mainly used to place battery components required for power;

[0047] The third area is mainly used to place electronic components;

[0048] The fourth area is mainly used to place the drive motor and reduction gearbox used for power drive.

[0049] The remaining gaps are used to place small and light components, which are reasonably placed in the above four areas according to the weight of each piece, so as to achieve a 50:50 weight layout and make the weight of the trolley basically evenly distributed.

[0050] This application optimizes the installation of the overall accessories of the four-way vehicle. The related sensor controls, switches, circuit boxes, etc. are designed to be placed on the outside of the four-way vehicle for easy maintenance and to free up the middle position inside the vehicle body for easy placement design. The interior of the vehicle body is then divided into four equal areas. The reasonable distribution of the installation positions of the accessories in the overall area makes the entire vehicle body as Figure 1 The center axis shown in the figure is taken as the standard, and the mass ratio on both sides of the vehicle body is 1:1, reaching 50%:50% of the vehicle body weight, so that the four-way vehicle will not deflect due to uneven weight of the vehicle body when moving, and the walking route will not be offset, and it will not be able to accurately reach the designated position, resulting in low work efficiency.

[0051] like Figure 6 、 Figure 7 As shown, in this embodiment, the vehicle frame 1 is provided with an outer frame 4 , and two adjacent outer frames 4 are provided with a fastening assembly 401 .

[0052] Both ends of the outer frame of the four-way vehicle are respectively provided with buckle components, which strengthens the stress-bearing strength of the overall structure. The buckle structure is easier to disassemble and assemble, which is convenient and labor-saving.

[0053] In this embodiment, a driving device 5 is provided on the vehicle frame 1;

[0054] Wherein, the driving device 5 includes a first driver 501 and a second driver 502;

[0055] The driving device 5 further includes a first rotating shaft 503 and a second rotating shaft 504;

[0056] The first rotating shaft 503 is rotatably connected to the first driver 501 through a first transmission belt 505; a first transmission chain 507 and a second transmission chain 508 of the same length are provided at both ends of the first rotating shaft 503 for driving the transverse wheels 506 on both sides, wherein the upper end surfaces of the first transmission chain 507 and the second transmission chain 508 are provided with a plurality of first pressure wheels 509, and the lower end surfaces of the first transmission chain 507 and the second transmission chain 508 are provided with a plurality of second pressure wheels 510 that cooperate with the first pressure wheels 509, and the first pressure wheels 509 and the second pressure wheels 510 respectively apply upper and lower pressure to the first transmission chain 507 and the second transmission chain 508, so that the first transmission chain 507 and the second transmission chain 508 are in a tensioned state during transmission;

[0057] Among them, the second rotating shaft 504 is rotatably connected to the second driver 502 through a second transmission belt 511; a third transmission chain 513 and a fourth transmission chain 514 of the same length are provided at both ends of the second rotating shaft 504 for driving the longitudinal wheel 512, and a third pressure wheel 515 is provided on the upper end surface of the third transmission chain 513 and the fourth transmission chain 514. The third pressure wheel 515 applies downward pressure to make the third transmission chain 512 and the fourth transmission chain 514 in a tensioned state during transmission.

[0058] like Figure 2 、 Figure 3 As shown, the entire vehicle body is equipped with two drives to control the wheels on all four sides. The first drive controls the transmission chains on both sides simultaneously through the first rotating shaft, and the second drive controls the front and rear rotating chains simultaneously through the second rotating shaft, achieving synchronous and uniform speed during driving.

[0059] Two first pressure wheels that apply downward pressure to the transmission chains are provided on the upper sides of the first transmission chains and the second transmission chains on both sides, and second pressure wheels that match the first pressure wheels are provided on the lower sides of the first transmission chains and the second transmission chains. The upper and lower pressure wheels are partially relative to each other, and compared with the height ratio of the two ends of the first shaft, the position of the first pressure wheel is lower than the height of the first shaft. In this way, downward pressure can be applied to the upper ends of the first transmission chains and the second transmission chains, and the second pressure wheels form an upper and lower clamping state, so that the above two transmission chains are in a tensioned state. During transmission, the transmission chain is in a close contact state, which allows the transmission chain to fit more closely to the shaft, and more effectively protects the transmission chain from fitting tightly to the shaft. In this way, the transmission chain can be prevented from falling off and running out due to the relatively long transmission chain when the four-way vehicle is moving.

[0060] Because the third and fourth transmission chains are relatively short, a third pressure wheel is only installed on the upper side of the transmission chain. This wheel applies downward pressure to the third and fourth transmission chains. Because the third and fourth transmission chains are relatively short, a single pressure wheel can achieve tension and fit. Due to limited space, a third pressure wheel prevents the transmission chains from scraping the bottom during operation. The front wheels at both ends can drive the rear wheels.

[0061] A pressure wheel is installed on the transmission chain to make the transmission chain fit more closely to the rotating shaft, preventing the transmission chain from falling off, causing the vehicle body to deflect during movement and causing the direction of travel to shift. The entire vehicle is driven by two drives, reducing the weight of the vehicle body and achieving lightweight construction.

[0062] In this embodiment, a plurality of tension adjusters 104 for adjusting tightness are provided on the outer frame 1 , and an adjustment block 1041 for adjusting the pressure wheel is provided on the tension adjuster 104 .

[0063] like Figure 7-9As shown, the tension adjuster's external mounting nut is pre-tightened, the adjustment block has a threaded hole, and a screw is installed on the outside of the outer frame. The tension adjuster is adjusted via a bolt. The outer bolt rotates, causing the threads on the bolt and the inner threads of the adjustment block to rotate. As needed, the bolt is turned left or right, causing the tension adjuster's pressure wheel to move back and forth, adjusting the pressure wheel height. When the adjustment block is adjusted to the appropriate position, the nut on the outside of the housing is preloaded to position the pressure wheel, tightening the drive chain and achieving the desired chain adjustment effect. The upper and lower pressure wheels on the same side are fixed to the same tension adjuster.

[0064] like Figure 4 As shown, in this embodiment, a plurality of cylinders 6 are provided on the inner and outer sides of the frame 1, and a lifting plate 7 for lifting goods is provided on the cylinders 6 on the same side.

[0065] When transporting goods, the lifting plate is lifted by the cylinder and then the goods are lifted.

[0066] like Figure 5 As shown, in this embodiment, an oil circuit board 8 is provided on the vehicle frame 1 , a hidden hole 9 is opened in the oil circuit board 8 , and a plurality of oil circuit blocks 10 are provided on the oil circuit board 8 .

[0067] A concealed hole is opened in the oil circuit board, and a hole is opened on the oil circuit board to connect the concealed hole with the oil circuit block. The concealed hole in the oil circuit board is used to supply oil, replacing the original leaky oil circuit pipe, making the entire oil circuit lighter and reducing the corresponding volume and weight.

[0068] In this embodiment, the outer frame 4 is made of 45# steel with a thickness of 11-13 mm.

[0069] The outer frame is made of 45# steel with a thickness between 11-13mm, preferably 12mm. Using 45# steel and a 12mm thickness for the outer frame reduces the weight without compromising strength, thus achieving a lightweight vehicle body.

[0070] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other embodiments whose principles and basic structures are the same or similar to those of the present application are within the scope of protection of the present application.
