[0002] Today, almost all cars, from small family sedans to SUVs, are equipped with central control displays; "LCD central control screens" have become standard equipment in automobiles. From models costing tens of thousands to millions of yuan, none are exempt from featuring such displays. With the increasing popularity of automobiles, the production of automotive cover glass has also increased significantly. At the same time, in the mobile phone market, due to short product replacement cycles and high demand, the demand for mobile phone cover glass is even greater. The rapid development of these two markets has driven the large-scale and efficient production of cover glass.

[0003] In the production process of cover glass, some processes use fixed workbenches as temporary storage platforms during product processing. This forces operators to frequently change platforms when handling products or materials of different sizes, increasing the complexity of the work. Furthermore, these fixed workbenches cannot be raised or lowered to different heights for easy retrieval, further exacerbating the inconvenience and difficulty of operation.

[0004] Therefore, how to provide a lifting device and transportation equipment that can flexibly adapt to cover glass of different sizes and can be raised and lowered is an urgent problem to be solved. Utility Model Content

[0030] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0031] The inventors discovered that with the increasing popularity of automobiles and the growing production of automotive cover glass, coupled with the huge demand for cover glass in the mobile phone market, the inconvenience of platforms in the cover glass manufacturing process has become increasingly prominent. Currently, the temporary platforms used in cover glass processing are mostly fixed workbenches, which necessitates frequent platform changes when handling products of different sizes, increasing operational complexity. Furthermore, these fixed platforms cannot be height-adjusted, making manual lifting or lowering of the cover glass both inconvenient and prone to accidents, further exacerbating the operational difficulty and inconvenience.

[0032] The first aspect of this disclosure provides a lifting device, comprising: a base 1 having a bearing surface 101; two first movable arms 2 rotatably connected to the bearing surface 101 of the base 1; an adjusting member 3 movably connected to the ends of the two first movable arms 2 opposite to the bearing surface 101; two second movable arms 4 movably connected to the top of the adjusting member 3; a plurality of carrying plates 5 disposed at the ends of the second movable arms 4 opposite to the adjusting member 3, and the plurality of carrying plates 5 being movably connected to each other to form carrying surfaces 51 of different areas; and a driving member 6, which drives the adjusting member 3 to slide the two first movable arms 2 and the two second movable arms 4 relative to the adjusting member 3, thereby changing the distance between the carrying plates 5 and the bearing surface 101.

[0033] Specifically, such as Figures 1-4As shown, the base 1 supports the entire device and has a bearing surface 101, allowing it to be stably placed on the floor of the production workshop. The size and shape of the base 1 can be customized according to actual needs. The first movable arm 2 and the second movable arm 4 can be rod-shaped or plate-shaped structures, etc. One end of the first movable arm 2 can be hinged to the bearing surface 101 of the base 1 via a rotating shaft, and the other end can be slidably connected to the adjusting member 3 via a slider or threaded sleeve 33. One end of the second movable arm 4 can be connected to the adjusting member 3 via a slider or threaded sleeve 33, and the other end can be connected to the carrying plate 5. The number of carrying plates 5 can be multiple, such as 2, 4, or 5, etc. The sizes of the multiple carrying plates 5 can be the same or different. The ends of the two second movable arms 4 that are away from the first movable arm 2 can both be connected to one carrying plate 5. Adjacent carrying plates 5 can be connected together via hinges, and there is a certain rotation angle between two adjacent carrying plates 5, so that the entire carrying surface 51 can be unfolded or folded as needed. A sliding rail mechanism can be used between two adjacent carrying plates 5 to expand or contract the carrying plates 5 in a specific direction, thereby quickly changing the size of the carrying surface 51 without disassembling any parts. The adjusting component 3 may include a lead screw, which is a rod with a helical groove. When it rotates, the thread on it interacts with the nut inside the slider to push the slider to move along the extension direction of the lead screw, thereby changing the angle between the first movable arm 2 and the bearing surface 101 and the angle between the second movable arm 4 and the bearing plate, thereby changing the distance between the carrying plate 5 and the bearing surface 101.

[0034] The lifting device and transport equipment disclosed herein include a base 1, a drive unit 6, a first movable arm 2, an adjusting unit 3, a second movable arm 4, and a carrying plate 5. Two first movable arms 2 symmetrically arranged on the bearing surface 101 of the base 1 are linked to the upper second movable arm 4 via the adjusting unit 3, forming a double parallelogram lifting mechanism. When the drive unit 6 pushes the adjusting unit 3, the included angle of the two pairs of movable arms changes synchronously, thereby adjusting the height of the carrying plate 5. Simultaneously, multiple modularly arranged movable connecting carrying plates 5 can be freely combined to form carrying surfaces 51 of different areas. This device can both adjust the lifting height of the carrying plate 5 and achieve flexible expansion and contraction of the carrying surface 51, effectively solving the problems of low changeover efficiency and poor human-machine adaptability of traditional fixed platforms.

[0035] In some embodiments, the adjusting member 3 includes: a movable frame 31 having a receiving space; a lead screw 32 rotatably connected to the two side walls of the movable frame 31 and having threaded sections with opposite directions of rotation; and two threaded sleeves 33 respectively fitted onto the two threaded sections, with each threaded sleeve 33 connected to a first movable arm 2 and a second movable arm 4; at least one end of the lead screw 32 is connected to the driving end of the driving member 6 and rotates under the drive of the driving member 6 to drive the threaded sleeves 33 to slide relative to the lead screw 32.

[0036] Specifically, such as Figures 1-2 As shown, the movable frame 31, serving as the basic framework of the entire adjusting component 3, can be made of metal. The movable frame 31 has an internal space for installing and protecting other key components (such as the lead screw 32 and threaded sleeve 33). Holes are provided on both side walls of the movable frame 31 to allow the lead screw 32 to pass through and rotate. The lead screw 32 is the core transmission component of the adjusting component 3, with its two ends connected to the side walls of the movable frame 31 via bearings, ensuring its free rotation. The lead screw 32 can be provided with two sections of threads with opposite directions of rotation, one left-handed and the other right-handed. When the lead screw 32 rotates, the two oppositely oriented thread sections can simultaneously drive the mating threaded sleeve 33 to move in opposite directions. The two threaded sleeves 33 are respectively installed on the two different thread sections of the lead screw 32. Each threaded sleeve 33 is securely connected to one end of the first movable arm 2 or the second movable arm 4, so that when the lead screw 32 rotates, the threaded sleeve 33 slides along the lead screw 32, thereby pushing or pulling the corresponding movable arm for angle adjustment.

[0037] When the height of the carrying plate 5 needs to be adjusted, the drive unit 6 is activated to rotate the lead screw 32. Since the lead screw 32 has two threads with opposite directions of rotation, when the lead screw 32 rotates, the two threaded sleeves 33 will move in opposite directions. This changes the relative position and angle between the first movable arm 2 and the second movable arm 4, thereby adjusting the height of the carrying plate 5. Furthermore, by adjusting the way the carrying plates 5 are connected, they can be flexibly combined to form carrying surfaces 51 of different areas as needed.

[0038] In some embodiments, the adjusting member 3 includes: a housing 14 having an accommodating space; a first adjusting rod 12 disposed in the accommodating space and rotatably connected at both ends to the side walls of the housing 14, and two first movable arms 2 having their ends opposite to the bearing surface 101 movably connected to the first adjusting rod 12; a second adjusting rod 13 having the same extending direction as the first adjusting rod 12, disposed in the accommodating space and rotatably connected at both ends to the side walls of the housing 14, and two second movable arms 4 having their ends opposite to the carrying plate 5 movably connected to the second adjusting rod 13; the driving member 6 includes: a first driving member 61 for driving the first adjusting rod 12 to rotate; and a second driving member 62 for driving the second adjusting rod 13 to rotate.

[0039] Specifically, such as Figure 3As shown, the housing 14 serves as the outer shell of the entire adjusting component 3, and its interior has sufficient space to accommodate the first adjusting rod 12, the second adjusting rod 13, and related components. The first adjusting rod 12 is disposed within the accommodating space of the housing 14, and its two ends are rotatably connected to the side walls of the housing 14 via bearing seats 17. One end of each of the two first movable arms 2 (the end furthest from the bearing surface 101 of the base 1) is movably connected to the first adjusting rod 12 via threaded sleeves 33 or sliders, so that the first movable arms 2 adjust their angle and position according to the rotation of the first adjusting rod 12. The second adjusting rod 13 is arranged parallel to the first adjusting rod 12 within the same accommodating space, and is also rotatably connected to the side walls of the housing 14 via bearing seats 17. One end of each of the two second movable arms 4 (the end furthest from the carrying plate 5) is also movably connected to the second adjusting rod 13 via similar threaded sleeves 33 or sliders. The function of the second adjusting rod 13 is to adjust the position of the second movable arms 4, thereby changing the height and tilt of the carrying plate 5. The first drive component 61, which can be an electric motor or a servo motor, drives the first adjusting rod 12 to rotate. It can achieve precise control of the first adjusting rod 12 through direct drive or indirect methods such as gear transmission. The movement of the first drive component 61 can be controlled independently to adapt to different operational needs. The second drive component 62, which can be an electric motor or a servo motor, drives the second adjusting rod 13 to rotate. It can operate independently as needed, enabling the second movable arm 4 to adjust its height and angle without relying on the first movable arm 2.

[0040] By adjusting the first movable arm 2 and the second movable arm 4 respectively using two drive components 6, it can be used to efficiently handle and position items of different sizes and weights. For example, when handling large sheets, the sheet can be quickly and accurately lifted to a specified height by simultaneously adjusting the first adjusting rod 12 and the second adjusting rod 13, and the sheet can be kept horizontal by fine-tuning the second adjusting rod 13; for smaller or lighter objects, precise positioning may only require slight adjustment of the second adjusting rod 13.

[0041] In some embodiments, a preset distance is provided between the two ends of the two first movable arms 2 connected to the base 1, and the preset distance is greater than or equal to the width of the carrier plate 5 in the sliding direction of the two first movable arms 2.

[0042] Specifically, since the distance between the first movable arms 2 is less than the width of the carrying platform 5, in some situations (e.g., when the goods on the carrying platform 5 are unevenly distributed), the center of gravity of the entire device may deviate from the support area formed between the two first movable arms 2, thereby increasing the risk of tipping over. To enhance the stability of the lifting device, the preset distance between the two first movable arms 2 at both ends of the base 1 can be greater than or equal to the width of the carrying platform 5 in the sliding direction of the two first movable arms 2, thus ensuring that the carrying platform 5 remains stable throughout the operation.

[0043] In some embodiments, the lifting device further includes: a card seat 7, which is rotatably connected to the carrier plate 5, and the card seat 7 is provided with a locking hole 8, the edge of the locking hole 8 being provided with a compression gap 9 extending radially from the locking hole 8 to the outer peripheral edge of the card seat 7.

[0044] Specifically, such as Figures 1-4 As shown, the card holder 7 can be rotatably connected to the side of the carrier plate 5 or the carrier surface 51 via a rotating shaft or other structure, allowing the card holder 7 to rotate freely to adapt to different locking requirements or position adjustments. The card holder 7 can be of any shape, such as a plate-like structure or a block-like structure, and there can be multiple card holders 7; no specific limit is placed on the number of card holders 7 here. The card holder 7 has a locking hole 8 at its center, the size and shape of which are customized according to specific application requirements (e.g., circular, square, etc.), for inserting the corresponding locking pin or other fixing device. The edge of the locking hole 8 has one or more extrusion slots 9 extending radially to the outer periphery of the card holder 7. The card holder 7 is made of a material with a certain degree of elasticity (such as high-strength plastic or a specific alloy), so that when locking pins of different sizes are inserted, the extrusion slots 9 can slightly expand or contract, adaptively conforming to the shape of the locking pin and providing a stable locking effect.

[0045] In some embodiments, the lifting device further includes a buffer member disposed between the second movable arm 4 and the carrying plate 5, and the buffer member is extendable and retractable in a direction perpendicular to the bearing surface 101.

[0046] Specifically, a buffer is located between the second movable arm 4 and the carrying plate 5, ensuring its free extension and retraction in a direction perpendicular to the bearing surface 101. The buffer can be made of materials with good elasticity and shock absorption properties, such as rubber, polyurethane, or other composite materials. The buffer can be a spring, sheet metal, or other structure. The presence of the buffer significantly reduces the risk of damage to goods caused by vibration and impact during handling, making it particularly suitable for handling fragile or vibration-sensitive items. It also helps to balance the load distribution on the carrying plate 5, making the entire lifting device more stable and reliable.

[0047] In some embodiments, the lifting device further includes: a shelf 10 disposed on the carrying plate 5, the shelf 10 having a shelf surface extending in a direction perpendicular to the carrying surface 101; and a plurality of isolation members 11, each isolation member 11 having an isolation portion 111, and the plurality of isolation members 11 being slidably connected to the shelf surface.

[0048] Specifically, such as Figure 4As shown, the shelf 10 is mounted on the carrier plate 5. The shelf 10 has a shelf surface extending in a direction perpendicular to the carrier surface 101, and the size of the shelf surface can be set according to actual needs. Multiple separators 11 are connected to the shelf surface via slide rails or other forms of sliding mechanisms. Each separator 11 is equipped with a separator section 111 for placement between adjacent items to be transported; here, the item to be transported is a glass plate as an example. The separator section 111 can be a simple block or a soft strip structure, ensuring that it serves as a separator without scratching the glass plate.

[0049] First, place the glass panels one by one on the shelf 10. Before placing each glass panel, insert appropriate spacers 11 on both sides. This effectively secures the position of each glass panel and prevents them from contacting each other. During the operation of the lifting device, the spacers 11 ensure that the glass panels will not collide even in the event of slight vibration or sudden stop, thus greatly reducing the risk of breakage. Upon reaching the destination, carefully remove the spacers 11 and unload the glass panels in reverse order.

[0050] In some embodiments, the lifting device further includes a movable component disposed on the base 1.

[0051] Specifically, the moving component can be directly installed under the base 1 to ensure that the entire lifting device can move smoothly on the ground. The moving component may include wheels, which can be made of durable polyurethane or rubber to provide good wear resistance and shock absorption, and can be omnidirectional or fixed wheels. The moving component may also include retractable support feet, which can be lowered to increase stability and reduce pressure on the wheels when the lifting device reaches the designated position and is ready for lifting operations.

[0052] In some embodiments, the lifting device further includes a backup power supply connected to the drive unit 6 for supplying power to the drive unit 6.

[0053] Specifically, the backup power supply can have an automatic charging function, automatically charging the backup battery while the main power supply is working normally and keeping it in optimal condition. Different types of batteries can be selected as backup power supplies, with common options including lead-acid batteries, lithium batteries, and nickel-cadmium batteries. When the main power supply is working normally, the drive unit 6 is powered by the main power supply, while the backup power supply is in standby mode and receiving charging. In the event of a sudden power outage from the main power supply, the power management system will quickly detect the situation and automatically transfer the load to the backup power supply. At this time, the drive unit 6 continues to be powered by the backup power supply, ensuring uninterrupted operation.

[0054] A second aspect of this application provides a transportation device, comprising: a plurality of lifting devices, each lifting device comprising: a base 1 having a bearing surface 101; two first movable arms 2 rotatably connected to the bearing surface 101 of the base 1; an adjusting member 3 movably connected to the ends of the two first movable arms 2 opposite to the bearing surface 101; two second movable arms 4 movably connected to the top of the adjusting member 3; a plurality of carrying plates 5 disposed at the ends of the second movable arms 4 opposite to the adjusting member 3, and the plurality of carrying plates 5 being movably connected to each other to form carrying surfaces 51 of different areas; and a driving member 6, wherein the adjusting member 3 is driven by the driving member 6 to cause the two first movable arms 2 and the two second movable arms 4 to slide relative to the adjusting member 3, thereby changing the distance between the carrying plates 5 and the bearing surface 101.

[0055] This embodiment describes a novel transportation device that integrates multiple lifting devices as described above. This transportation device can be a transport vehicle, which not only possesses the mobility of a traditional transport vehicle but also achieves efficient loading, unloading, and handling of goods through its multiple lifting devices. First, the transport vehicle is driven into the loading area, the lifting devices are adjusted to a suitable height, and then a forklift or other tools are used to place the goods on the loading platform 5, with spacers 11 inserted as needed to prevent collisions. After loading is complete, the transport vehicle's drive system is activated, and it travels to the target storage area along a preset route. During the journey, the route can be adjusted in real time using the onboard navigation system to avoid obstacles. Upon arrival at the destination, the lifting devices are used again to precisely align with the shelf position, safely unload the goods, and organize them for storage. By integrating multiple lifting devices, rapid transfer of goods from the ground to higher levels is achieved, reducing the time and labor intensity of manual handling. Whether handling small packages or large mechanical parts, this transport vehicle can meet diverse needs thanks to its flexible lifting device configuration.

[0056] The transportation equipment disclosed herein includes a base 1, a drive unit 6, a first movable arm 2, an adjusting unit 3, a second movable arm 4, and a carrying platform 5. Two first movable arms 2 symmetrically arranged on the bearing surface 101 of the base 1 are linked to the upper second movable arm 4 via the adjusting unit 3, forming a double parallelogram lifting mechanism. When the drive unit 6 pushes the adjusting unit 3, the included angle of the two pairs of movable arms changes synchronously, thereby adjusting the height of the carrying platform 5. Simultaneously, multiple modularly arranged movable connecting carrying platforms 5 can be freely combined to form carrying surfaces 51 of different areas. This device can both adjust the lifting height of the carrying platform 5 and achieve flexible expansion and contraction of the carrying surface 51, effectively solving the problems of low changeover efficiency and poor human-machine adaptability of traditional fixed platforms.
