Description

Technical Field

[0001] This utility model belongs to the field of steering wheel technology, specifically relating to a lifting steering wheel. Background Technology

[0002] Steering wheels are mainly used on transport vehicles such as AGVs (Automated Guided Vehicles). A specially designed wheel, the steering wheel plays a crucial role in the transport vehicle. First, it supports the weight of the transport vehicle, ensuring its stability during movement. Second, the steering wheel's rotation drives the transport vehicle forward or backward. Finally, through the steering mechanism, the steering wheel enables the transport vehicle to steer, allowing it to move flexibly in various environments. Structurally, it includes: 1. A steering motor, providing power to rotate the steering wheel; 2. A steering coupling plate, controlling the direction of the steering wheel's rotation, thus controlling the AGV's direction of travel; 3. A travel motor, controlling the steering wheel's movement; 4. A gear set, transmitting power from the motor to the steering wheel, enabling it to drive the AGV's movement and steering; 5. A hydraulic rod, providing shock absorption and smoother power output.

[0003] For example, in the prior art, CN217804313U discloses a differential steering wheel with suspension and swing capability, which includes a first motor, a drive wheel, a steering wheel mounting plate, a connecting plate, a fixed seat, and hydraulic rods. The top of the first motor is fixedly connected to the steering wheel mounting plate, and the drive wheel is rotatably connected to one side of the steering wheel mounting plate. The drive wheel has two sets and is symmetrically arranged on both sides of the steering wheel mounting plate. The top of the steering wheel mounting plate is rotatably connected to the connecting plate, and the fixed seat is fixedly connected to one side of the bottom of the connecting plate. The hydraulic rods have two sets and are symmetrically arranged on the other side of the bottom of the connecting plate. When in use, the hydraulic rods can play a shock-absorbing role, and the use of the three internal motors also plays a good role in balance and stability, resulting in smoother power output.

[0004] Analysis of existing technologies reveals that existing steering wheels only provide shock absorption and do not lift the vehicle body. Furthermore, the application range of steering wheels is limited. Adding a lifting mechanism would increase the complexity of the steering wheel structure and hinder space conservation.

The lifting steering wheel 100 also has a shock-absorbing state. When in the shock-absorbing state, hydraulic oil is stored in the lifting cylinder 103.

[0031] Please refer to Figures 2-7 In another aspect, this utility model provides a lifting and transporting vehicle.

[0032] The lifting transport vehicle includes a vehicle body 200, a gyroscope 300, a controller, and multiple lifting steering wheels 100. The lifting steering wheels 100, vehicle body 200, and controller are respectively mounted on the vehicle body 200. The lifting steering wheels 100 and gyroscope 300 are respectively signal-connected to the controller.

When the drive wheel 110 rises to a preset maximum lifting height, it is exactly located on the left detection block 118, which limits its upward movement. The shorter block on the right is the lower limit block, whose lateral extension is located above the right detection block 118. When the drive wheel 110 descends to a preset minimum height, it is exactly located on the right detection block 118, which limits its downward movement.

[0035] Please refer to Figure 3 and Figure 7 In a preferred embodiment, the lifting steering wheel 100 further includes a hinged shaft seat 107, a balance shaft 108, a steering wheel bracket 109, and a drive wheel 110. The upper end of the hinged shaft seat 107 is fixedly connected to the second mounting base 102, and the lower end of the hinged shaft seat 107 is hinged to the upper end of the balance shaft 108. The lower end of the balance shaft 108 is connected to the steering wheel bracket 109. The hinged shaft seat 107, the balance shaft 108, and the steering wheel bracket 109 are coaxially arranged in the left-right direction. The drive wheel 110 is arranged on both the front and rear sides of the rotation axis of the steering wheel bracket 109.

[0036] Please refer to Figure 7Furthermore, there are two hinged axle seats 107, two balance shafts 108, and two drive wheels 110. The two hinged axle seats 107 are spaced apart from each other on the left and right sides. The upper end of the hinged axle seat 107 is provided with an upwardly protruding axle seat mounting block. The second mounting seat 102 is provided with a corresponding axle seat mounting position 117 that mates with the axle seat mounting block. The two balance shafts 108 are spaced apart from each other on the left and right sides, and their rotation axes are on the same straight line in the left and right directions. The left and right ends of the two balance shafts 108 are respectively hinged to the hinged axle seats 107 located on the left and right ends. The steering wheel bracket 109 includes a front wheel connecting plate, a rear wheel connecting plate, two left axle connecting plates, and two... The right axle connecting plate, two left axle connecting plates, and two right axle connecting plates are located inside the two hinged axle seats 107, and are arranged alternately on the left and right sides. The middle parts of the two left axle connecting plates are connected to the left-end balance shaft 108, the rear ends of the two left axle connecting plates are connected to the rear wheel connecting plate, and the front ends of the two left axle connecting plates are connected to the front wheel connecting plate. The middle parts of the two right axle connecting plates are connected to the right-end balance shaft 108, the rear ends of the two right axle connecting plates are connected to the rear wheel connecting plate, and the front ends of the two right axle connecting plates are connected to the front wheel connecting plate. The two drive wheels 110 are respectively installed on the front side of the front wheel connecting plate and the rear side of the rear wheel connecting plate. Figure 7 For reference, when the lifting wheel 100 encounters an inclined ground that is higher in the front and lower in the back, the front and rear drive wheels 110 of the lifting wheel 100 rotate around the balance shaft 108. The front drive wheel 110 is adaptively raised and the rear drive wheel 110 is adaptively lowered, so that the two wheels can be supported on the inclined ground. During this process, the first mounting base 101 and the second mounting base 102 remain horizontal.

[0037] Please refer to Figure 3 In a preferred embodiment, the lifting steering wheel 100 further includes a travel motor 111 and a differential 116. The travel motor 111 is driven by the differential 116, and there are two drive wheels 110, each connected to the differential 116. The differential 116, also known as a differential gear set, enables the left and right wheels of the vehicle to rotate at different speeds when the vehicle is turning, thereby achieving vehicle steering.

[0038] Please refer to Figures 3 to 6 ,in Figure 6 The steering gear 114 is already concealed. In a preferred embodiment, the output end of the steering motor 113 is also provided with a steering gear 114, which meshes with the slewing support 112 and drives the slewing support 112 to rotate. The slewing support 112 is a steering gear 114 disc, which supports and is mounted on the vehicle body 200. The steering motor 113 drives the steering gear 114 disc and the vehicle body 200 to steer.

[0039] Please refer to Figures 3 to 7In a preferred embodiment, a reducer is provided between the drive motor and the differential 116, and the reducer is driven by both the drive motor and the differential 116. A reducer is also provided between the steering motor 113 and the steering gear 114. The main function of the reducer is to reduce the rotational speed and increase the torque. By reducing the input shaft speed, the high-speed, low-torque input shaft is transformed into a low-speed, high-torque output shaft to meet various operational requirements. Simultaneously, the reducer can also slow down the angular velocity of the output shaft, achieving a larger reduction ratio. The reducer can reduce the rotational speed of the steering wheel, thereby better controlling the vehicle's steering. The differential 116 enables the lifting steering wheel 100 to have a differential steering wheel function.

[0040] Please refer to Figure 6 In a preferred embodiment, the lifting cylinder 103 is fixedly connected to the second mounting base 102. The output end of the lifting cylinder 103 is provided with a lifting output rod 104. The lifting output rod 104 is fixedly connected to the first mounting base 101. When hydraulic oil is input into the lifting cylinder 103 or withdrawn from the lifting cylinder 103, it drives the lifting output rod 104 to extend and retract with the lifting cylinder 103 in the up and down direction.

[0041] Please refer to Figure 6 In a preferred embodiment, the lifting steering wheel 100 further includes a hydraulic supply station 105, which is mounted on the second mounting base 102. The output and input ends of the hydraulic supply station 105 are connected to the hydraulic input and hydraulic output ends of the lifting cylinder 103, respectively. After supplying hydraulic oil to the lifting cylinder 103, the hydraulic supply station 105 extracts the hydraulic oil from the lifting cylinder 103. The hydraulic supply station 105 and the lifting cylinder 103 are connected by a pipeline. When lifting is required, the hydraulic supply station 105 pumps the hydraulic oil from the hydraulic input end into the lifting cylinder 103, causing the lifting output rod 104 to extend relative to the lifting cylinder 103, and the first mounting base 101 to rise to a predetermined height. When lowering is required, the hydraulic supply station 105 extracts part of the hydraulic oil from the lifting cylinder 103, causing the lifting output rod 104 to shorten relative to the lifting cylinder 103, and the first mounting base 101 to descend to a predetermined height. When the lifting wheel 100 is not suspended in the air, there is no need to adjust the lifting wheel and the vehicle body 200. Since the lifting cylinder 103 retains some hydraulic oil, it can play a good role in shock absorption.

[0042] Please refer to Figure 6 In a preferred embodiment, the second mounting base 102 is provided with two cylinder mounting positions 106, and the lifting cylinders 103 are fixedly connected to the two cylinder mounting positions 106 respectively through flanges; the upper end of the lifting output rod 104 is also fixedly connected to the first mounting base 101 through a flange.

[0043] Working principle of this utility model:

[0044] Please refer to Figures 2-7 The vehicle body 200 is generally equipped with four lifting wheels 100. When the lifting transport vehicle needs to load and unload goods, it is necessary to raise or lower the vehicle body 200 as a whole. When the vehicle body 200 needs to be raised as a whole, the hydraulic supply station 105 supplies hydraulic oil to the lifting cylinders 103 on each lifting wheel 100, raising the vehicle body 200 to a predetermined position to match the height of other handling tools or loading platforms. Lowering the vehicle body 200 as a whole is the reverse of raising the vehicle body 200, and will not be described in detail here. During the operation of the vehicle body 200, when the four lifting wheels 100 are not suspended in the air, it is not necessary to adjust the lifting wheels and the vehicle body 200. Since some hydraulic oil is retained in the lifting cylinders 103, it can play a good role in shock absorption. When one of the lifting steering wheels 100 is suspended in the air, the gyroscope 300 feeds back the tilt detection information to the controller. The controller controls the corresponding tilted lifting steering wheel 100 according to the detection information, so as to increase or decrease the hydraulic oil in its lifting cylinder 103, thereby adjusting the height of the lifting steering wheel 100 and the vehicle body 200 at that point, so as to ensure that the first mounting seat 101 and the vehicle body 200 are always on the same horizontal plane. In this state, the two drive wheels 110 of the lifting steering wheel 100 at this point rotate due to the cooperation of the balance shaft 108 and the steering wheel bracket 109, so that the two drive wheels 110 adapt to the uneven and inclined ground, so that the two drive wheels 110 can contact and support the inclined ground.

[0045] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
