Automated adjustable equipment for loading motorcycles and goods

Abstract

The invention relates to an automatic ramp for loading and transporting motorcycles and goods, having a system that allows adjustment of the length of the base and the height of the rear portion of the folding platform, so that the ramp can adapt to the size of the body of any motor vehicle with cargo loading space, or to a space-limited fixed base. When the device is installed on the pickup truck, the device can be operated whether a truck cover of the pickup truck is opened or closed. When the folding platform is used in other spaces, the height of the rear portion of the folding platform can be adjusted to increase the free space below the folding platform. An automatic ejection system is arranged, and the platform is automatically pushed away from the equipment by starting a motor unit. The automatic equipment is composed of a motor unit, an adjustable base assembly, a coupleable adjustable inclination assembly, a main tray assembly, a folding platform assembly and an automatic rebound system, and further comprises a sliding frame assembly with a motorcycle wheel supporting piece and a coupleable assembly used for various bearing objects, so that the automatic equipment is multifunctional.

Description

Technical Field

[0001] This application relates to an automated loading and unloading system for motorcycles and various types of cargo. The system is foldable and adjustable in length and height. It features a tilting system and an automatic rebound system. The tilting system includes a bottom propulsion mechanism that does not interfere with the width of the cargo. The system can be installed on a motor vehicle with cargo space or a fixed base, providing an automated, safe, and reliable system for loading and unloading motorcycles and cargo. Background Art

[0002] The service segment for transporting motorcycles and general cargo using multi-purpose vehicles like pickup trucks continues to grow. This market segment is highly competitive, requiring service providers to deliver high-quality services and differentiate themselves. Safely and efficiently loading motorcycles and cargo remains a key challenge for this service sector.

[0003] While purchasing specialized equipment is a solution, existing commercially available models are limited to specific vehicle models or spaces—they must be customized to the vehicle body or cannot be adjusted in length and height for deployment in specific, space-constrained locations. Furthermore, these devices lack fully automated loading and unloading systems, requiring manual labor for some processes.

[0004] Furthermore, users face the same dilemma when loading motorcycles and other equipment into their own pickup trucks. Commercially available equipment lacks flexibility in length and height. Consequently, when purchasing automated equipment, they are ultimately limited to the dimensions of the vehicle body at the time of manufacture and cannot adapt to different vehicle specifications or even smaller spaces. Summary of the Invention

[0005] The purpose of the present invention is to enable users to flexibly use their devices in motor vehicles with stowage space, or in fixed bases with space limitations, such as in showcases or displays for motorcycles and other stowages.

[0006] While retaining the automation system, the outstanding advantages of this application are that the equipment can be folded when idle, the base length can be adjusted, and the height of the tail of the folding platform can be adjusted.

[0007] The device's adjustable length and height, along with its foldable storage capabilities, allow users to install it on other cargo vehicles of varying specifications while maintaining its operational characteristics. For fixed bases, the length and height adjustment features help position the device in confined areas. The device's rear lift is particularly suitable for exhibitors, and it can be folded to reduce space usage when not in use.

[0008] The device is multifunctional as it has a carriage (7) for carrying the motorcycle and an attachable load trolley ( Figure 2 ), allowing for automatic and adjustable loading of various types of loads.

[0009] The device also has flexibility in usage mode, and the device can be used in a flat form by either raising the part of the folding platform component (6) through the adjustable tilt component (5) or not attaching the component.

[0010] In addition, the device has a set of traction springs (4), which, through the coordinated action with other components, can automatically pop out the folding platform component (6), so that no human intervention is required during the unloading process. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] The adjustable automated device according to the figure is driven by a motor unit (1), preferably using an electric winch (8) equipped with an upper reinforced handle (9) designed to accommodate the full extension of the pulling element (71) during loading and unloading. The motor unit (1) must be fixed to the motor unit support (20) of the adjustable base assembly (2) by means of fixing elements (73), preferably screws.

[0062] The adjustable base assembly (2) comprises an adjustable motor unit support frame (18), a base and a threaded bushing (12) for adjusting the length of the base. The adjustable motor unit support frame (18) has an adjustment hole (22). The base has a telescopic device housing (10). These structures enable the base length to be adjusted. Figure 4After positioning at the desired length, the adjustable motor unit support frame (18) is fixedly connected to the base (10) with the telescopic device housing by means of fixing elements (73) which are preferably screws, using adjustment holes (22) and threaded bushings (12) for adjusting the base length.

[0063] Figure 13 The adjustable base assembly (2) is shown in three positions during length adjustment, thereby allowing the same device to be deployed in spaces of different lengths.

[0064] The total length of the base can also be extended by the main telescopic device assembly (3). The assembly has an assembly profile (24) with an adjustment hole (22), which together with the telescopic device structural beam (23) form the structure of the telescopic device ( Figure 5 When the mounting profile (24) is distributed inside the telescopic device slot (11) constituting the end of the base (10) with the telescopic device slot, the main telescopic device assembly (3) can be adjusted in length relative to the adjustable base assembly (2).

[0065] After positioning according to the required length, Figure 14 As shown, the main telescopic device assembly (3) can be locked by inserting the locking pin (17) into the adjustment hole (22). The figure shows three different positions of the main telescopic device assembly (3) coupled to the adjustable base assembly (2) during the length adjustment process. When not in use, the locking pin (17) should be stored in the support tube (16) to prevent it from loosening.

[0066] The main telescopic device assembly (3) will serve as a support for part of the structure of the folding platform assembly (6). In conjunction with the adjustable base assembly (2), which includes a lifting crossbar (13) with coupling bushings, they will jointly assume the supporting function, ensuring that the weight carried by the device is completely borne by the adjustable base assembly (2). The adjustable base assembly (2) needs to be fixed to the desired surface, such as the vehicle body, using fixing elements (73), preferably screws, via base fixing points (91).

[0067] In this manner, the adjustable base assembly (2) when used in a pickup truck supports the weight of the cargo on the device without the need for support or reliance on the hood ( Figure 30 ), or when used in a space-constrained location, there is no need for a structure to support the entire extension of the device ( Figure 31 ).

[0068] The device has two modes of use: coupled with the adjustable tilt assembly (5), or not coupled with the assembly. When not coupled with the adjustable tilt assembly (5), or when the fixing element (73) is removed from the propulsion element (70) fixed to the tilt position adjustment tube (48), the folding platform assembly (6) will remain in a horizontal position after loading. Figure 19 As shown, part of the platform tubular structure (40) will be supported on the main telescopic device assembly (3) when in use.

[0069] To optimize space utilization (the tilted state can reduce the space occupied by the equipment and cargo), the adjustable tilt assembly (5) and the propulsion element (70) can be coupled to the adjustable base assembly (2) and the folding platform assembly (6). Thus, when loaded, part of the folding platform assembly (6) will be as follows Figure 21 shown raised, its weight supported by the adjustable tilt assembly (5) to allow Figure 24 The main telescopic device assembly (3) is shown closed.

[0070] like Figure 35 As shown, when the adjustable tilt assembly (5) is assembled to the adjustable base assembly (2), a fixing element (73) preferably a screw is used to fix the connection terminals of the lifting frame (30) (located at both ends of the lifting frame tubular structure (29)) to the lifting crossbar (13) with coupling bushings of the adjustable base assembly (2).

[0071] like Figure 36 As shown, the propulsion system operates as follows: one end of the propulsion element (70) is fixed to the propulsion element fixing bracket (21) of the adjustable base assembly (2), so that it passes between the propulsion roller (34) and the lifting frame tubular structure (29), and the other end is fixed (preferably using a screw) to the tilt position adjustment tube (48) of the folding platform assembly (6).

[0072] The tilt position adjustment tube (48) of the folding platform assembly (6) is provided with an adjustment mechanism, which can adjust the final position of the tilt lifting frame (27) after adjusting the length of the adjustable base assembly (2), thereby allowing the device to be tilted at different angles and different sizes.

[0073] The tilt lift frame (27) is provided with a slot (32) into which the main telescopic device structure (35) is fitted. After the desired position is determined, the tilt height adjustment telescopic device (28) is fixed to the tilt lift frame (27) using a fixing element (73), preferably a screw, through the adjustment hole (22) of the main telescopic device structure (35) and the locking hole (31) of the lifting frame tubular structure (29). Figure 16 Three positions of the adjustable tilt assembly (5) during height adjustment are shown.

[0074] The structure of the tilt height adjustment telescopic device (28) of the adjustable tilt assembly (5) includes a compression spring (39) fixed by a spring bracket (36). The compression spring (39) has the function of pushing the adjustable tilt assembly (5), thereby lifting the folding platform assembly (6), and serves as a propulsion device to assist in lifting the load. At the same time, it also has a shock-absorbing function because it can absorb the impact force during the descent of the adjustable tilt assembly (5).

[0075] The tilt height adjustment telescopic device (28) has lateral guides / stops with rollers (38) mounted on the shaft (37). Figure 22 and 23 As shown, these lateral guides / stops with rollers (38) can ensure that the folding platform assembly (6) is always on the main telescopic device structure (35) and does not exceed the side range of the tilt height adjustment telescopic device (28) during loading and unloading and after completion. In addition, the lateral guides / stops with rollers (38) can be rotated so that the folding platform assembly (6) can be Figure 21 Scroll as shown.

[0076] The height adjustment function of the adjustable tilt assembly (5) allows defining the height position of the roller-mounted lateral guide / stop (38), thereby allowing the device to be used on a variety of motor vehicle models, such as Figure 33 and 34 As shown, a pickup truck equipped with tailgates of different heights can still close the tailgate after loading the cargo. The height adjustment is performed by the linkage of the tilting lifting frame (27) and the tilting height adjustment telescopic device (28).

[0077] The propulsion system of this equipment allows tilting operations for large loads. Figure 21 As shown, the entire lifting process is completed below the folding platform assembly (6) without the need for lateral arms, thereby allowing cargo of different sizes to be loaded without interfering with other parts of the equipment.

[0078] The propulsion system allows a single motor unit (1) to be driven to perform the loading and unloading processes of the carriage assembly (7), the stowage and deployment of the folding platform assembly (6), and the tilting of the adjustable tilt assembly (5).

[0079] When not in use, the device, whether or not coupled to the adjustable tilt assembly (5), can be folded to reduce the space it occupies, such as within the body of a pickup truck. Figure 32 As shown, the tailgate and cargo box rainproof tarpaulin can be closed normally. The folding platform assembly (6) has a platform tubular structure (40) and a slide profile / guide (41) with a platform hinge (43) to allow the folding platform assembly (6) to be folded. In addition, the main telescopic device assembly (3) can be retracted to make the device appear as shown. Figure 25 The compact form shown.

[0080] Figure 28 In FIG. 1 , it is observed that the device is not coupled to the adjustable tilt assembly (5), and the folding movement of the folding platform assembly (6). Next, Figure 29 The closing movement process of the main telescopic device assembly is shown. Figure 26 and Figure 27 The device is viewed from two different perspectives, with the device coupled to the adjustable tilt assembly (5), the folding platform assembly (6) in a closed position, and the main telescopic device assembly (3) in a retracted position.

[0081] When using the device, the main telescopic device assembly (3) is opened and adjusted according to the required length. The folding platform assembly (6) is opened and properly locked by using the fixing element (73) preferably a screw through the folding platform fixing slot (47) to keep the folding platform assembly (6) opened.

[0082] The device has an adjustable locking system for the folding platform assembly (6). The main telescopic device assembly (3) is composed of main platform guides (25), which, in addition to acting as lateral guides during the installation and removal of the folding platform assembly (6), also have holes to allow adjustment of the locking of the folding platform assembly (6) relative to the adjustable base assembly (2) at different height positions.

[0083] During loading and unloading, when the folding platform assembly (6) reaches the bottom surface and completes the travel through the adjustable base assembly (2) and the main telescopic device assembly (3), the folding platform assembly (6) is locked. The locking can be achieved by inserting the locking pin (17) of the main telescopic device assembly (3) into the hole of the main platform guide (25). Since the guide has more than one hole, the holes can be adjusted as needed to lock the folding platform assembly (6) at more than one tilt angle.

[0084] In this way, the device can be used in loading scenarios of different heights, such as various models of motor vehicles with cargo space, or benches and display cabinets, etc., and locked to ensure safe operation of the device.

[0085] like Figure 11 As shown, the device has a carriage assembly (7) consisting of a carriage tubular structure (55) with a traction element bracket (59). The assembly is connected to the power unit (1) via a traction element (71) preferably made of polyester strips through the traction element bracket (59). When the motor unit (1) is started, as shown in FIG. Figure 19 As shown, the carriage assembly (7) will be pulled along the platform tubular structure (40) of the folding platform assembly (6) by the pulling element (71).

[0086] The carriage assembly (7) has the function of distributing the tires of the motorcycle wheels. The access ramp (63) plays a guiding role when pushing the motorcycle, guiding the wheels / tires to the wheel lock hinge (56). The wheel hinge (56) has a position for distributing the tires ( Figure 18 ) and assists the assembly movement of the tire. The wheel articulator (56) has an axle sleeve (58) that allows the articulator to be positioned in the positioner (57).

[0087] The position adjustment of the wheel lock hinge (56) allows the allocation of wheels / tires of different sizes. When a tire located in the hinge is allocated and pushed forward, it is pushed forward until it contacts the folding front bracket (60). For such adjustment, the desired position of the wheel lock hinge (56) is selected in the position adjuster (57) and fixed with the fixing element (73) via the shaft sleeve (58).

[0088] The folding front support (60) has a front support hinge (61) which is fixed to a hinge bracket (62) welded to the carriage tubular structure (55) by means of a fixing element (73) which is preferably a screw. When the device is idle, the front support hinge (61) and the hinge bracket (62) allow the folding front support (60) to be folded in the desired direction. Figure 25 Fold as shown.

[0089] The carriage assembly (7) also has an automatic locking member (64), which is fixed to the carriage tubular structure (55) via a locking member base (67), a locking member shaft (68) and a locking member fixing element (69) which is preferably a screw. The automatic locking member (64) has a compression spring (66) to enable the locking member with a spring support (65) to move. The locking member with a spring support (65) is a hook-shaped structure that can find and fix itself in the automatic locking positioner (42) when the carriage assembly (7) moves along the platform tubular structure (40) in the folding platform assembly (6).

[0090] The device is multifunctional in use and after removing the folding front bracket (60), wheel lock hinge (56) and access ramp (63) from the carriage assembly (7), it can be coupled with the attachable loading platform assembly (74) to load such as Figure 2 Various types of cargo shown are of larger size and shape.

[0091] Figure 37 and 38The structure of the attachable loading platform assembly (74) is shown in detail. The assembly has a loading base (75) mounted on a loading structural frame (77). The structural frame has lateral fences (76) and tie-down points (78) on the sides and front to ensure the safety of cargo loading and unloading. Structural frame rollers (80) and bottom support rollers (82) are provided at the bottom of the loading structural frame (77) to assist the upward and downward movement of the assembly.

[0092] The hinged ascending ramp (79) is fixed to the rear of the load structure frame (77) through the ascending ramp hinge (81), so as to facilitate the load to enter the load base (75). The ascending ramp is provided with an ascending ramp fixing point (90) at the end. The ascending ramp fixing point (90) is a threaded bushing and can be locked with the lateral fence (76) through the ascending ramp fixing knob (89).

[0093] In this way, as Figure 46 and 47 As shown, when loading cargo, the ascending ramp fixing knob (89) needs to be removed so that the ascending ramp (79) is lowered to become an extension of the cargo floor (75). After loading is completed, the ascending ramp (79) needs to be vertically positioned and re-fixed on the side fence (76) of the attachable cargo platform assembly (74).

[0094] The attachable platform assembly (74) can be coupled to the device using a coupling frame (83). To ensure coupling efficiency and accurate positioning, Figure 44 As shown, the coupling frame (83) is fixed to the hinge bracket (62) of the carriage assembly (7) via the fixing element (73).

[0095] like Figure 43 As shown, the coupling frame (83) has a movable coupling lock (84), which is to be assembled and positioned on the carriage assembly (7) and needs to be correctly locked by a fastening / locking element (87) preferably a screw. The frame has a hinge center bushing (86), which will cooperate with the lateral hinge bushing (85) at the lower front of the load-bearing structure frame (77) and be fixed by a hinge shaft (88).

[0096] After the coupling is completed, the attachable loading platform assembly (74) will be properly fixed in the carriage assembly (7), and the loading and unloading process will be performed by starting the motor unit (1). Figure 39 As shown, when the motor unit (1) is started, the attachable loading platform assembly (74) will slide along the rear tire base (44) of the folding platform assembly (6) with the assistance of the bottom support rollers (82) until the structural frame rollers (80) reach the bottom surface and the slide assembly (7) completes the travel of the entire extension of the folding platform assembly (6).

[0097] The utility model also has an automatic rebound system, which allows the part of the device to be ejected outward in an automated manner. Figure 17 As shown, the system uses a tension spring assembly (4), which is characterized in that a strip spring is used to generate tension when the device is loaded. When the traction unit is activated in the downward direction, the spring tension forms a reverse force, and the folding platform assembly (6) is automatically popped out through the traction element (72) of the spring assembly.

[0098] like Figure 49 As shown, the tension spring assembly (4) is fixed in the main telescopic device assembly (3), one end of the traction element (72) of the spring assembly is fixed in the strip spring bracket inside the spring assembly (4), and the other end is fixed in the bracket (52) of the traction element of the spring assembly of the folding platform assembly (6).
