Description

Technical Field

[0001] This invention belongs to the field of industrial transportation equipment technology, and specifically relates to a transportation protective frame for motorcycle production. Background Technology

[0002] In the motorcycle production process, the transportation links, such as the transfer of finished and semi-finished products between workshops, the allocation within the factory, and the connection with warehousing, are crucial to ensuring production continuity and product quality. Currently, the industry commonly uses simple rigid transport frames, secured with ropes or basic metal baffles, with the entire loading, unloading, and securing process relying on manual operation. These devices are designed solely to achieve basic load-bearing capacity and are not optimized for actual working conditions such as road bumps and differences in motorcycle models during transportation.

[0003] In recent years, the variety of motorcycle models has continued to expand, with significant differences in size, weight, and structure between different models such as motorcycles, scooters, and off-road vehicles. Traditional transport racks, lacking flexible adjustment structures, struggle to accommodate the needs of securing multiple models, often resulting in unstable mounting and unbalanced stress. Furthermore, the absence of effective shock absorption design means that vibrations from starting, braking, and uneven road surfaces during transport can easily cause scrapes on the motorcycle and loosening of parts. Manual operation is not only inefficient but also carries the risk of goods slipping due to inadequate securing.

[0004] The significant shortcomings of traditional transport racks have become an obstacle to enterprise development. High product damage rates lead to increased rework costs and material losses, and their high reliance on manual labor makes them difficult to match the fast-paced demands of modern production lines, thus restricting the improvement of production automation levels. Therefore, developing transport protective racks with intelligent adjustment, reliable shock absorption, and multi-vehicle compatibility has become an urgent need to solve industry pain points. Summary of the Invention

[0005] To address the aforementioned problems in the existing technology, this invention provides a transport protective frame for motorcycle production. It solves the problems of traditional transport frames in motorcycle production and transportation, such as the lack of flexible adjustment structure making it difficult to adapt to multiple models, the lack of effective shock absorption design causing product damage, low efficiency of manual operation, and safety risks, which in turn restrict enterprises from improving quality and efficiency and upgrading to automation.

[0006] The objective of this invention can be achieved through the following technical solution: a transport protective frame for motorcycle production, comprising a lifting mechanism, a support frame, a body support plate, a front wheel fixing mechanism for fixing the motorcycle, and a main body fixing mechanism; the upper end of the lifting mechanism is connected to the transport frame, and the lower end is connected to the support frame, with the body support plate mounted on the support frame; the protective frame integrates a shock-absorbing device and an intelligent control system electrically connected to the lifting mechanism; wherein, the shock-absorbing device is disposed between the support frame and the body support plate to absorb vibrations during transportation; the intelligent control system is used to automatically adjust the lifting speed of the lifting mechanism and the damping characteristics of the shock-absorbing device according to the transportation environment and weight data collected by a weight sensor.

[0007] As a preferred embodiment of the present invention, the shock-absorbing device includes at least one elastic buffer pad disposed at the bottom of the vehicle body support plate or a variable damping shock absorber controlled by the intelligent control system.

[0008] As a preferred embodiment of the present invention, the intelligent control system includes a central processing unit, a weight sensor connected to the support frame, and a vibration sensor connected to the shock-absorbing device; the central processing unit adjusts the operating parameters of the lifting mechanism and the shock-absorbing device in real time based on the data collected by the weight sensor and the vibration sensor.

[0009] As a preferred embodiment of the present invention, the motorcycle front wheel fixing mechanism includes a front wheel bracket, a front wheel fixing baffle, and a V-shaped fixing plate; the front wheel bracket is obliquely raised at the front end of the vehicle body support plate, and the rearward-facing V-shaped fixing plate is provided on the rear side of the upper end; the front wheel fixing baffle is an upward-facing concave arc-shaped surface, and its bottom is hinged to the vehicle body support plate through a pivot, located behind the front wheel bracket.

[0010] As a preferred embodiment of the present invention, the motorcycle body fixing mechanism includes a body fixing rod; the bottom of the body fixing rod is hinged to the support frame via a pivot, and the upper end is provided with a latch for locking the motorcycle body; the body fixing rod is limited by the side of the support frame and cannot be flipped backward.

[0011] As a preferred embodiment of the present invention, the lifting mechanism is a pair of symmetrically arranged hydraulic rods, which are connected to the hydraulic unit controlled by the intelligent control system.

[0012] As a preferred embodiment of the present invention, it further includes a pair of symmetrically arranged balance support plates. Each balance support plate includes an upper folding plate and a lower folding plate that are hinged to each other. The upper end of the upper folding plate is hinged to the transport frame, and the lower end of the lower folding plate is hinged to the support frame, which is used to enhance the stability of the lifting process.

[0013] As a preferred embodiment of the present invention, it further includes an anti-falling locking device, which is installed on the support frame and corresponds to the locking hole on the transport vehicle frame.

[0014] As a preferred embodiment of the present invention, the anti-fall locking device includes an electronically controlled triggering mechanism, a transmission mechanism, and a safety device pin; the electronically controlled triggering mechanism is controlled by the intelligent control system; the transmission mechanism connects the electronically controlled triggering mechanism and the safety device pin, and is used to transmit the action of the electronically controlled triggering mechanism to the safety device pin; the safety device pin has a spring reset function; after the lifting position is reached, the intelligent control system controls the electronically controlled triggering mechanism to move, and pushes the safety device pin out through the transmission mechanism and inserts it into the lock hole of the transport frame to achieve automatic locking; after receiving an unlocking command, the intelligent control system controls the electronically controlled triggering mechanism to reset, and the safety device pin automatically retracts and unlocks under the action of the spring.

At the same time, the electronically controlled anti-fall locking device, anti-rollover limit design, and V-shaped front wheel fixing mechanism constitute multiple safety protections, greatly enhancing operational safety. The combination of a symmetrical hydraulic lifting mechanism and a hinged balance support plate ensures stable and reliable lifting. In addition, the adjustable width support frame design gives the protective frame both excellent buffering performance and wide adaptability, effectively reducing motorcycle transport damage and improving its practical value on the production site.

[0021] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0022] Please see Figure 1 and Figure 2 This embodiment provides a transport protective frame for motorcycle production. The overall structure of the protective frame is designed to be suspended under a transport frame 12. The transport frame 12 can be a pre-installed aerial track system within the factory area or a load-bearing structure for heavy transport vehicles, thereby achieving efficient space utilization and automated process integration. The core load-bearing part of the protective frame mainly includes a liftable support frame 11 and a vehicle body support plate 3 firmly installed on the support frame 11. The latter directly contacts the motorcycle body, providing it with a stable support surface.

[0023] The load-bearing system design of this invention fully considers the characteristics of modern motorcycle production lines, such as multiple models, variable batch sizes, and fast pace. To solve the multi-model compatibility problem mentioned in the background art, the left and right sides of the support frame 11 are designed with retractable sleeve-type telescopic rod structures. Multiple sets of adjustment holes are evenly opened along the length direction at the joint between the inner and outer rods, and are locked by length adjustment pins 9. The operator can easily pull out the pin according to the width of the motorcycle to be transported, adjust the width of the support frame 11 to the appropriate position, and then reinsert it to lock. This allows the effective load-bearing width of the protective frame to be adjusted in steps within a certain range, ensuring that the motorcycle is always in a centered, balanced, and stable state during transportation, fundamentally avoiding the problem of instability caused by size mismatch.

[0024] Above the support frame 11, a flat vehicle support plate 3 is installed. The surface of this support plate is covered with a high-density anti-slip rubber layer and has drainage grooves. This increases the friction between the motorcycle tires and the plate surface, preventing accidental slippage during loading and unloading, and also allows for quick drainage of water after rain or washing, keeping the contact surface dry. The connection between the support plate and the lower support frame 11 is not rigid, but rather a flexible connection via a shock-absorbing device detailed later. This is crucial for achieving shock absorption during transport.

[0025] The lifting function of this invention is achieved by a precision-controlled hydraulic system. As the core of the lifting mechanism, a pair of symmetrically arranged hydraulic rods 6 are respectively installed on the left and right sides of the protective frame. The upper end of each hydraulic rod 6 is connected to the upper transport frame 12, and the lower end is connected to the support frame 11. This symmetrical layout ensures that the lifting force is evenly applied to both sides of the load center, avoiding uneven loading and tilting that may be caused by single-point lifting. The power for the hydraulic rods 6 comes from an integrated hydraulic unit, which includes an oil tank, a motor, a hydraulic pump, and a solenoid valve assembly, and is connected to the hydraulic rods 6 via conduits. The operation of the entire hydraulic unit is completely controlled in a closed-loop manner by the intelligent control system described later, enabling millimeter-level precise positioning and stepless speed control.

[0026] To further ensure ultimate stability and lateral stiffness during lifting and lowering, this invention also features a pair of symmetrical balance support plates 7. Each balance support plate 7 consists of an upper folding plate and a lower folding plate hinged together by a pivot. The upper end of the upper folding plate is hinged to the transport frame 12, and the lower end of the lower folding plate is hinged to the support frame 11. The transport frame 12, the upper folding plate, the lower folding plate, and the side beams of the support frame 11 together form a four-bar linkage. When the hydraulic rod 6 drives the support frame 11 to lift and lower, this four-bar linkage effectively restrains any swaying or torsion of the protective frame in the horizontal plane, ensuring that it can only move vertically. This further enhances the stability of the lifting and lowering process, effectively preventing the protective frame from swaying even at the moment of start-stop or when the load is not completely centered, providing a solid mechanical guarantee for the safety of the motorcycle.

[0027] Furthermore, a mechanical stroke limit block is added to the outside of the hydraulic cylinder 6. The position of the limit block can be adjusted by bolts, which can precisely limit the maximum extension and retraction of the piston rod according to the height requirements of different motorcycle models. This prevents the support frame 11 from falling too low and hitting the ground, or rising too high and squeezing the transport frame 12 due to excessive stroke. At the same time, a high-elasticity polyurethane buffer pad is attached to the contact point between the limit block and the end of the piston rod. When the piston rod extends or retracts to its limit position, the buffer pad can absorb the impact energy between the end and the limit block, preventing abnormal noise and structural damage caused by rigid collision. In addition, a copper-based alloy bushing with self-lubricating function can be nested at the hinge joint between the lower end of the hydraulic rod 6 and the connecting lug plate of the support frame 11. This bushing not only reduces the frictional resistance when the trunnion rotates, ensuring smooth operation when the hydraulic rod 6 drives the support frame 11 to rise and fall, but also buffers the stress through the slight deformation of the bushing when the support frame 11 generates a small lateral force due to a slight load shift, preventing the connecting lug plate from cracking due to long-term lateral force. At the same time, it improves the durability of the connection between the hydraulic rod 6 and the support frame 11, ensuring stable coordination between the two in long-term high-frequency lifting and lowering operations.

[0028] To ensure that the motorcycle is securely locked under any transportation conditions, this invention designs two sets of complementary fixing mechanisms, one at the front and one at the rear.

[0029] First is the motorcycle front wheel fixing mechanism located at the front end of the vehicle support plate 3. This mechanism consists of three parts: a front wheel bracket 1 that slopes upwards, with a rearward-facing V-shaped fixing plate 10 on its upper rear side; and an arc-shaped front wheel fixing baffle 2 located behind the front wheel bracket 1. When the motorcycle is pushed onto the protective frame, the front wheel will first contact the inclined surface of the front wheel bracket 1 and roll upwards. At this time, the V-shaped fixing plate 10 plays a crucial guiding and self-locking role. Its V-shaped groove can automatically align the front wheel to the center position and use gravity to wed it into the groove, achieving initial limiting. Immediately afterwards, the operator or automated mechanism can flip the front wheel fixing baffle 2, which is hinged to the vehicle support plate 3 at the bottom via a pivot, upwards. Its concave arc-shaped surface can perfectly fit the rear contour of the motorcycle's front wheel, completely restricting the possibility of the front wheel rolling backwards. This simple forward push and upward flipping action completes the reliable fixing of the front wheel in both the front-rear and left-right directions.

[0030] Secondly, there is the motorcycle body fixing mechanism used to secure the main body of the motorcycle. This mechanism mainly includes one or more body fixing rods 5, the bottom of which are also hinged to the side of the support frame 11 via a pivot. After the motorcycle is fully in place, the body fixing rod 5 is flipped forward so that the rubber-coated buckle at its upper end can firmly lock the motorcycle frame, engine guard, or other sturdy parts. To prevent the fixing rod from accidentally flipping backward and becoming loose during severe bumps, a mechanical limiting block corresponding to the fixing rod is specially designed on the side of the support frame 11. When the fixing rod is flipped into place, its body will abut against the limiting block, thus physically eliminating any possibility of it flipping backward, forming a simple and extremely reliable anti-loosening safety device.

[0031] It should be noted that the anti-fall locking device is installed on the support frame 11 and includes an electrically controlled triggering mechanism 4, a transmission mechanism 13, and a safety pin 8. The electrically controlled triggering mechanism 4 (such as an electromagnet or a micro motor) is controlled by an intelligent control system. The transmission mechanism 13 (such as a push rod, cable, or linkage) connects the electrically controlled triggering mechanism 4 and the safety pin 8. The safety pin 8 has a built-in return spring. When the lifting mechanism drives the support frame 11 to rise and fall to the target position, the intelligent control system sends a signal to the electrically controlled triggering mechanism 4, which then activates. Through the transmission mechanism 13, the safety pin 8 is pushed against the spring force to extend and precisely insert into the corresponding lock hole of the transport frame 12, achieving automatic locking. When unlocking is required, the system controls the electrically controlled triggering mechanism 4 to de-energize or reverse its action. The thrust of the transmission mechanism 13 is released, and the safety pin 8 automatically retracts under the action of its internal return spring, disengaging from the lock hole, thus completing the unlocking. This structure can effectively prevent the support frame 11 from detaching from the transport frame 12 in the event of an unexpected hydraulic system failure, ensuring the safety of the transportation process.

[0032] Another key innovation of this invention lies in its integrated adaptive shock absorption device. This device is cleverly positioned between the motorcycle's body support plate 3 and the underlying support frame 11, effectively adding a vibration isolation layer to the vibration transmission path. Depending on cost and performance requirements, this device can be implemented in two specific schemes: Option 1: Passive elastic buffer pads. Multiple buffer pads made of high-damping polyurethane or special rubber are evenly distributed at the bottom of the vehicle body support plate 3. These materials possess excellent elasticity and energy absorption characteristics, effectively absorbing and attenuating high-frequency, low-amplitude vibrations generated during transportation due to uneven road surfaces or vehicle start-stop cycles, providing basic protection for the motorcycle's paint and precision electronic components. This option is simple in structure, highly reliable, and maintenance-free.

[0033] Option 2: Utilizing active variable damping shock absorbers. This is a more advanced configuration, installing one or more shock absorbers, such as magnetorheological shock absorbers, directly controlled by an intelligent control system between the support plate and the support frame 11. These shock absorbers are filled with magnetorheological fluid, whose viscosity (i.e., damping force) can change dramatically within milliseconds depending on the applied magnetic field strength. Through linkage with vibration sensors (described later), the control system can sense vibration intensity in real time and instantly adjust the current applied to the shock absorber, thereby precisely altering its damping characteristics. For example, when encountering severe impacts such as speed bumps, the system instantly increases damping to powerfully absorb impact energy; while on flat roads, it decreases damping, keeping the suspension system softer and further weakening the transmission of minor vibrations, providing more stable load protection for the motorcycle.

[0034] To achieve automated and intelligent operation, this invention is equipped with an intelligent control system. The system's workflow is as follows: System startup and data acquisition: After the system is started, the weight sensor installed on the support frame 11 and the vibration sensor installed near the shock absorber begin to work, collecting the motorcycle's weight data and environmental vibration data in real time.

[0035] Central Processing Unit (CPU) Analysis and Adjustment: The CPU receives and analyzes sensor data. Based on the data from the weight sensor, the system can determine the motorcycle model and set an initial, safe lifting speed and a basic damping value. During transportation, based on real-time data collected by the vibration sensor, the CPU dynamically adjusts the damping characteristics of the variable damping shock absorber to achieve optimal shock absorption. Simultaneously, it also controls the hydraulic unit connected to hydraulic rod 6 to regulate the lifting speed.

[0036] Safety Locking and Continuous Monitoring: Once the lifting mechanism has raised or lowered the protective frame to its designated position, the system issues a command to control the anti-fall locking device installed on the support frame 11. The safety pin 8 of this device automatically inserts into the locking hole on the transport frame 12 under the action of the electrically controlled trigger mechanism 4, achieving mechanical locking and preventing falls due to unexpected hydraulic system failure. After locking, the system does not stop working but enters continuous monitoring mode, constantly analyzing vibration data and adjusting shock absorption damping to ensure the safety and stability of the entire transportation process. When unlocking is required, the operator issues a command, and the system controls the safety pin 8 to automatically retract before the next lifting operation can proceed.

[0037] In summary, this invention significantly improves the automation level, safety, and product protection of motorcycle transportation during the production process through integrated intelligent control, adaptive shock absorption, multiple safety locking mechanisms, and a multi-model adaptable structure, effectively solving many problems associated with traditional transport racks.
