[0002] In the manufacturing process of microvans, CNG cylinders typically need to be installed under the vehicle chassis. Due to differences in the structural design of different vehicle models, there are various requirements for the installation height and orientation of the cylinders. Currently, when production lines handle mixed production of multiple vehicle models, operators have to equip themselves with various lifting devices of different specifications to accommodate the cylinder installation requirements of different models. This operation method not only requires frequent equipment changes, resulting in a significant waste of non-productive time, but also leads to low equipment utilization when multiple lifting devices are used simultaneously. Furthermore, the maintenance costs of multiple lifting devices are high, they occupy a large production area, and seriously affect the overall operating efficiency of the production line. Existing technology lacks a cylinder installation lifting device that can adapt to various installation height and orientation requirements and can be used by multiple vehicle models. Therefore, existing technology urgently needs improvement to address these issues. Utility Model Content

[0027] like Figures 1-4 As shown, this utility model proposes a lifting device for vehicle processing.

[0028] In one exemplary embodiment, the vehicle processing lifting device includes:

[0029] A base 1, a fixed seat 2 is slidably connected to the base 1, and a moving mechanism is provided on the fixed seat 2, which can move in a first direction through the moving mechanism;

[0030] Mounting plate 12, with a support plate 13 on the side of mounting plate 12 away from base 1. The support plate 13 is rotatably connected to mounting plate 12. The support plate 13 is provided with a bracket 16 for mounting gas cylinders, and the bracket 16 can move in a second direction of the support plate 13.

[0031] A lifting mechanism is provided between the base 1 and the mounting plate 12. The lifting mechanism can be used to drive the mounting plate 12 to move upward in a third direction.

[0032] The first direction, the second direction, and the third direction are perpendicular to each other.

[0033] In this embodiment, the technical solution achieves omnidirectional adjustment of the gas cylinder installation position through the coordinated operation of three mutually perpendicular degrees of freedom of motion. The sliding engagement between the base 1 and the fixed seat 2 enables forward and backward displacement; the rotational connection between the mounting plate 12 and the support plate 13 enables angle adjustment; the lateral movement of the bracket 16 enables left and right position adjustment; and the lifting mechanism enables height adjustment. Each moving component adopts a modular design, allowing for rapid adjustment according to the gas cylinder installation requirements of different vehicle models. Compared with existing technologies, this device, through its integrated multi-directional adjustment mechanism, avoids the problem of frequent replacement of specialized equipment, significantly improving the efficiency and accuracy of gas cylinder installation.

[0034] For example, in this embodiment, when the tray 13 is not rotated, the extension direction of the base 1 is the first direction, the movement direction of the bracket 16 is the second direction, and the lifting direction of the lifting mechanism is the third direction.

[0035] It is worth noting that the movable mechanism enables precise positioning of the fixed base 2 on the base 1. The rotatable connection between the support plate 13 and the mounting plate 12 is achieved through a slewing bearing, which has high load-bearing capacity and self-locking function, and can stably maintain the rotation angle of the support plate 13. The movement of the bracket 16 on the support plate 13 is achieved through a T-slot guide rail in conjunction with a manual locking device, which facilitates the operator to adjust the lateral position according to the size of the gas cylinder. The lifting mechanism preferably adopts a scissor-type structure, driven by a hydraulic cylinder 11, which features smooth lifting and high load capacity.

[0036] In an exemplary embodiment, the tray 13 is provided with a slide rail 15, the bracket 16 is slidably connected to the slide rail 15, and both ends of the slide rail 15 are provided with limiting blocks 17 for limiting the position of the bracket 16.

[0037] In this embodiment, the slide rail 15 guides the bracket 16 to move along a straight path, eliminating the risk of lateral deviation. The rigid contact between the limiting block 17 and the end of the slide rail 15 precisely controls the movement stroke. Compared with free movement without a guide structure, this design ensures stable positioning of the gas cylinder during lifting and rotation, preventing excessive displacement due to inertia. Specifically, when the tray 13 is tilted, the limiting block 17 effectively prevents the bracket 16 from sliding out of the working area due to gravity, thereby improving operational safety when installing gas cylinders of various vehicle models. Through the synergistic effect of mechanical limiting and the guide structure, the operation process is simplified while ensuring positioning accuracy within ±2mm.

[0038] For example, in this embodiment, the bracket 16 can be moved manually on the tray 13, or it can be electrically controlled by a motor or lead screw structure to facilitate the adjustment of the position of the bracket 16.

[0039] It is worth noting that the slide rail 15 in this embodiment can adopt a structure such as a T-slot guide rail, a linear ball bearing guide rail, or a dovetail groove guide rail. The T-slot guide rail is fixedly connected to the support plate 13 by bolts, and the bottom of the support bracket 16 is provided with a slider that matches the shape of the slide rail 15. The limiting block 17 can be a rubber buffer block, a metal stop, or an adjustable mechanical limiter. For example, the metal stop is fixed to the end of the slide rail 15 by welding, and its height exceeds the upper surface of the slide rail 15 by 5-10mm to ensure effective blocking. As a preferred embodiment, the surface of the slide rail 15 can be provided with scale markings to facilitate the operator's visual judgment of the moving position of the support bracket 16.

[0040] In one exemplary embodiment, the tray 13 is provided with a rotating shaft 14, which is rotatably connected to the mounting plate 12.

[0041] In this embodiment, a rotation axis 14 is established through a rotating shaft 14, giving the pallet 13 the freedom to rotate around the axis. When the installation height or direction of the gas cylinder needs to be adjusted, the pallet 13 can rotate the entire gas cylinder to the target angle, and then fix it through a positioning mechanism. Compared with the existing technology that uses multiple sets of fixed-angle tooling, the rotating connection structure realizes multi-angle adaptation of a single device, eliminating tooling change time. Specifically, the rotating shaft 14 structure has the characteristics of strong load-bearing capacity and low rotational resistance, and can stably support the pallet 13 fully loaded with gas cylinders; at the same time, the mechanical rotating mechanism is intuitive to operate, requires no additional power source, and effectively improves the production line changeover efficiency. This design is particularly suitable for working conditions where the space under the chassis of microvan vehicles is limited, and the angle adjustment avoids interference between the equipment and the vehicle structure.

[0042] For example, in this embodiment, the tray 13 can be rotated manually or by setting a driving component (such as a motor or other equipment) to drive the tray 13 to rotate.

[0043] For example, the rotating shaft 14 can be a cylindrical metal shaft, with its two ends forming a rotating pair with the mounting plate 12 via bearings. As a preferred embodiment, the rotating shaft 14 and the support plate 13 are fixedly connected by welding or bolts to ensure reliable torque transmission. A U-shaped bracket can be provided on the mounting plate 12, which has a clearance fit with the rotating shaft 14 through a through hole, wherein the clearance is controlled within 0.05-0.1 mm to ensure smooth rotation. Furthermore, the surface of the rotating shaft 14 can be hardened to improve wear resistance, or grease grooves can be added to the contact surface to achieve long-term maintenance-free operation. Alternatively, the rotating shaft 14 can be replaced with a hinge structure, achieving a rotating connection via a pin.

[0044] For example, the rotation angle of the pallet 13 is 0°-90°. By limiting the free rotation of the pallet 13 within the range of 0° to 90°, the gas cylinder mounting plane can be flexibly switched between horizontal and vertical states. When facing differences in chassis height among different vehicle models, the vertical pallet 13 can reduce the overall installation height; when lateral installation space is required, the horizontal pallet 13 can expand the working range. This effectively solves the problem of limited gas cylinder installation direction caused by the variable vehicle structure. Compared with the fixed-angle pallet 13 structure in the prior art, it significantly improves the adaptability of a single device to working conditions and avoids efficiency losses caused by frequent changes of lifting devices. In a specific embodiment, the rotation angle range is achieved through the cooperation of the rotating shaft 14 and the limiting structure. The rotating shaft 14 adopts a hinged structure with bearings to ensure smooth rotation; the limiting structure includes a mechanical stop or angle sensor set on the mounting plate 12, which automatically stops when the pallet 13 rotates to 0° or 90°. As a preferred embodiment, angle adjustment can be completed manually or automatically controlled by an electric push rod. Angle scale markings are provided on the side of the pallet 13 to facilitate precise adjustment by the operator.

[0045] In an exemplary embodiment, the tray 13 is provided with a plurality of first positioning holes, and the mounting plate 12 is provided with a plurality of second positioning holes, wherein the first positioning holes can be used to engage with the second positioning holes for connection.

[0046] In this embodiment, the connection between the tray 13 and the mounting plate 12 can be achieved through the first positioning hole on the tray 13 and the second positioning hole on the mounting plate 12, so as to limit the rotation of the tray 13.

[0047] It is worth noting that the first and second positioning holes can be circular, square, or other geometric shapes, and the hole spacing is set according to the required adjustment angle range. As a preferred embodiment, the positioning holes are arranged in an arc-shaped array along the rotation axis of the support plate 13 and the mounting plate 12, allowing the support plate 13 to be adjusted in increments within the range of 0°-90°. The connecting parts can be pins, bolts, or quick-release pins, with a spring clip at the end of the pin to enhance connection stability. Furthermore, a wear-resistant bushing can be added to the inner wall of the positioning holes to extend their service life.

[0048] In an exemplary embodiment, the lifting mechanism includes a scissor lift unit 10 disposed between the fixed base 2 and the mounting plate 12, and the fixed base 2 is provided with a lifting motor 9 for driving the scissor lift unit 10 to rise or fall.

[0049] In this embodiment, smooth lifting is achieved through the mechanical characteristics of the scissor lift structure. The cross linkages maintain symmetrical movement during deployment, effectively counteracting lateral forces. The lifting motor 9 serves as the power source, and the control circuit enables precise stroke adjustment, solving the problem of inconsistent positioning accuracy during manual operation. Compared to conventional hydraulic lifting mechanisms, this solution offers advantages such as compact structure, high transmission efficiency, and easy maintenance, making it particularly suitable for space-constrained vehicle chassis operation environments. The motor drive can integrate a position sensor to form a closed-loop control, further improving the accuracy of height adjustment.

[0050] For example, the scissor lift unit 10 consists of multiple sets of cross-hinged connecting rods, each equipped with a hydraulic cylinder. The lifting motor 9 is electrically connected to the hydraulic cylinders for electrical control, achieving vertical lifting motion by extending or retracting the connecting rods. The lifting motor 9 can be a servo motor or a stepper motor, with its output shaft connected to the movable end of the scissor lift unit via a gear set or belt drive mechanism. In a preferred embodiment, the motor drives a worm gear mechanism to move the bottom crossbeam of the scissor lift unit, thereby achieving precise control of the lifting height. The top of the scissor lift unit is connected to the mounting plate 12 via a hinged seat, and the bottom is connected to the fixed base 2 via a slide rail 15 mechanism to ensure stability during the lifting process.

[0051] In an exemplary embodiment, the moving mechanism includes a drive motor 3 mounted on a base 1. The output end of the drive motor 3 is provided with a drag chain 4, and the free end of the drag chain 4 is provided with a drive wheel 5. The drive wheel 5 is rotatably connected to a fixed base 2. A driven wheel 6 is provided on the side of the fixed base 2 opposite to the drive wheel 5. The drive wheel 5 and the driven wheel 6 can be used to drive the fixed base 2 to move along the extension direction of the base 1.

[0052] In this embodiment, linear movement control of the fixed seat 2 on the base 1 is achieved through a combination of motor drive and wheel transmission. The drive motor 3 provides stable power output, the cable chain 4 transmits power, and the driving wheel 5 and driven wheel 6 form a stable transmission system. Specifically, the motor drives the cable chain 4, which in turn pulls the driving wheel 5 to rotate. The driving wheel 5 moves the fixed seat 2 through friction with the base 1 or gear meshing, while the driven wheel 6 provides auxiliary support and guidance. This solves the problems of inaccurate positioning and unstable movement inherent in traditional manual pushing or simple mechanical transmission, achieving precise and controllable movement of the fixed seat 2 on the base 1. Compared with existing technologies, this solution has advantages such as smooth transmission, accurate positioning, and convenient control.

[0053] For example, a first protective cover 7 is provided on the base 1 to protect at least a portion of the drive wheel 5, and a second protective cover 8 is provided on the base 1 to protect at least a portion of the driven wheel 6. The transmission components are physically isolated and protected by the split protective covers. Specifically, the first protective cover 7 blocks external foreign objects from entering the meshing area of ​​the drive wheel 5, preventing chain slippage or jamming; the second protective cover 8 shields the bearing area of ​​the driven wheel 6 from dust intrusion, reducing the risk of wear. Compared to the exposed transmission mechanism in the prior art, this design effectively solves the problem of wheel assembly being easily damaged by external forces during movement while ensuring transmission function through partial protection, extending the maintenance cycle of the lifting device in dusty environments. The split structure of the protective covers facilitates individual disassembly and maintenance without affecting the disassembly and repair of the transmission system. Furthermore, the first protective cover 7 and the second protective cover 8 can be made of metal stamping or engineering plastic injection molding, with stainless steel or aluminum alloy being preferred materials to balance strength and corrosion resistance. The coverage of the protective cover must meet the requirement that it can always cover the exposed rim portions of the driving wheel 5 and driven wheel 6 throughout their entire stroke as they move along the base 1. As a preferred embodiment, the first protective cover 7 can be designed as an inverted U-shaped structure, with its open end fixed to both sides of the base 1 by bolts; the second protective cover 8 can be an L-shaped bent plate, which is connected to the side wall of the base 1 by welding.

[0054] It is worth noting that the drive motor 3 can be a servo motor or a stepper motor to achieve precise speed and position control. The cable chain 4 can be made of metal or engineering plastic, with metal cable chains 4 suitable for heavy-duty applications and engineering plastic cable chains 4 suitable for light-duty applications requiring vibration damping. The surfaces of the drive wheel 5 and driven wheel 6 can be provided with anti-slip textures or covered with a rubber layer to increase the friction between them and the contact surface with the base 1. As a preferred embodiment, the drive wheel 5 and driven wheel 6 can adopt a gear structure, with a rack and pinion set at the corresponding position on the base 1, achieving more precise transmission through gear and rack meshing. Furthermore, a guide rail can be provided on the base 1, and a slider that cooperates with the guide rail can be provided at the bottom of the fixed base 2, thereby improving the straightness and stability of the movement.

[0055] In one exemplary embodiment, a control panel 18 is provided on the base 1, and the control panel 18 is electrically connected to the drive motor 3 and the lifting motor 9.

[0056] In this embodiment, through the centralized control function of the control panel 18, operators do not need to adjust the drive motor 3 and the lifting motor 9 separately; they only need to input commands on a single interface to synchronously coordinate the actions of the two motors. For example, when adjusting the installation position of the gas cylinder, the horizontal displacement of the moving mechanism and the vertical lifting of the lifting mechanism can be controlled simultaneously to achieve precise positioning in three-dimensional space. This design simplifies the operation process, reduces equipment debugging time, and is particularly suitable for scenarios where tooling is frequently changed in multi-vehicle production lines. Compared with the decentralized control lifting devices in the prior art, this solution avoids positional errors caused by asynchronous manual operation through an electrical signal linkage mechanism, improving the efficiency and safety of gas cylinder installation.

[0057] In a specific embodiment, the control panel 18 is preferably installed on the side of the base 1 in a convenient location, and the panel housing is made of an oil-resistant material. As a preferred embodiment, the control panel 18 may be equipped with an emergency stop button to immediately cut off the motor power in case of equipment malfunction. The connection lines between the panel and the motor can be routed along the internal wiring channels of the base 1 to avoid the risk of external entanglement.

[0058] In summary, the bracket 16 in this utility model can achieve multi-axis movement and rotation at any angle, making the installation position of the gas cylinder adjustable. It can be applied to various vehicle models, reducing the manufacturing cost for enterprises.

[0059] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
