Description

Technical Field

[0001] This utility model relates to the field of RV lifting equipment technology, specifically to an improved vehicle-mounted motorcycle bracket. Background Technology

[0002] Utility model patent CN218505764U discloses an automatic lifting platform for a motorcycle bracket in a motorhome, comprising a connecting frame, a fixed frame, and a support frame. The fixed frame is connected to the connecting frame, and the support frame is movably mounted on the fixed frame. A drive motor is mounted on the fixed frame, and a steel wire rope connects the drive motor and the support frame. The support frame includes a fixed column and a U-shaped frame. The fixed frame includes a guide tube, through which the fixed column passes. A limiting lifting mechanism is mounted on the fixed frame and cooperates with the fixed column. A fixed pulley is mounted on the U-shaped frame, and a take-up drum is mounted at the output end of the drive motor. One end of the steel wire rope is wound around the take-up drum, passes through the fixed pulley, and the other end is riveted to the fixed frame. In this type of automatic lifting platform for motorhome motorcycle brackets, when the drive motor lowers the support frame, the steel cable wound on the take-up drum is released, and the support frame descends under its own weight. When the support frame touches the ground, if the drive motor is not immediately shut off, the steel cable wound on the take-up drum will continue to be released, causing the steel cable release to become disordered. Therefore, there is an urgent need to improve the existing automatic lifting platform for motorhome motorcycle brackets. Utility Model Content

[0003] In view of the above, this utility model provides an improved vehicle-mounted motorcycle bracket that ensures the orderly release of the wire rope during the lifting process and avoids disordered release of the wire rope.

[0004] The technical solution of this utility model:

[0005] This utility model provides an improved vehicle-mounted motorcycle bracket, including a fixed frame, a lifting frame, a drive shaft, a drive wheel, and a steel wire rope. The lifting frame is slidably mounted on the fixed frame, the drive shaft is rotatably mounted on the fixed frame, the drive wheel is fixed to the drive shaft, and the steel wire rope is wound around the drive wheel. The upper and lower ends of the steel wire rope are respectively fixed to the upper and lower ends of the lifting frame. By driving the drive wheel to rotate, the steel wire rope is driven to pull the lifting frame up and down relative to the fixed frame.

[0006] Furthermore, it includes a lifting motor mounted on a fixed frame for driving the rotation of the drive shaft.

[0007] Furthermore, the output shaft of the lifting motor is connected to the transmission shaft to drive the transmission shaft to rotate. There are two transmission wheels, which are fixed at both ends of the transmission shaft respectively. There are two steel wire ropes, which are wound around the two transmission wheels respectively.

[0008] Furthermore, it also includes a sliding guide mechanism installed on the fixed frame, the sliding guide mechanism being used to install the lifting frame.

[0009] Furthermore, the sliding guide mechanism includes a guide member with a groove and a sliding roller. The guide member is fixed on the fixed frame, and the lifting frame is slidably installed in the groove of the guide member. Two sliding rollers that can rotatably clamp the two sides of the lifting frame are installed at the upper and lower ends of the guide member.

[0010] Furthermore, it also includes a locking mechanism installed on the fixed frame for locking the height position of the lifting frame.

[0011] Furthermore, the fixing frame includes two L-shaped frames for fixing to the vehicle body and a crossbeam connecting the two L-shaped frames, and the lifting motor is mounted on the crossbeam.

[0012] Furthermore, the lifting frame includes a frame and a support frame vertically fixed to the bottom of the frame for placing the motorcycle, and the two ends of the steel wire rope are respectively fixed to the upper and lower beams of the frame.

[0013] Furthermore, the lifting motor is a reversible motor, and the lifting frame can be raised and lowered by controlling its forward and reverse rotation.

[0014] Furthermore, the steel wire rope is wound in a single-layer spiral on the drive wheel. This improved vehicle-mounted motorcycle bracket has the following beneficial effects:

[0015] I. Orderly Release of Wire Rope: The improved vehicle-mounted motorcycle bracket ensures the orderly release of the wire rope during lifting and lowering, preventing erratic release. This is thanks to the unique design where both ends of the wire rope are fixed to the upper and lower ends of the lifting frame, respectively, and the middle part is wound around the drive wheel. This design allows the wire rope to maintain stable tension and movement trajectory during lifting and lowering, effectively preventing problems such as tangling and knotting, and ensuring the stability and reliability of the bracket's lifting and lowering.

[0016] II. Reduced Failure Rate: The orderly release design of the wire rope reduces the probability of failures caused by wire rope misalignment. In traditional brackets, misaligned wire rope release can lead to accelerated wire rope wear and damage to the drive wheel. This invention effectively avoids these problems, reducing the frequency and cost of bracket maintenance.

[0017] III. Enhanced Overall Structural Strength: The fixed frame provides a solid supporting foundation for the entire bracket system. The lifting frame is slidably mounted on the fixed frame, a structural design that allows the bracket to maintain good stability when bearing the weight of the motorcycle. Meanwhile, the rational layout and connection method of the drive shaft, drive wheel, and wire rope further enhances the structural strength of the entire bracket system, improving the bracket's load-bearing capacity and service life.

[0018] IV. Parking support function: By driving the transmission wheel to rotate, the steel wire rope is driven to pull the lifting frame up and down relative to the fixed frame. The lifting frame can actively descend to the ground, thus acting as a parking support leg and improving the stability of parking.

[0019] This utility model improves the vehicle-mounted motorcycle bracket by using a drive transmission wheel to drive a steel wire rope to achieve automated lifting of the lifting frame. It is simple and safe to operate and has a parking support function. Its unique steel wire rope fixing and winding design ensures the orderly release of the steel wire rope, enhances the overall structural stability, and reduces failures.

[0020] The preferred embodiments of this utility model and their beneficial effects will be further described in detail in conjunction with specific implementation methods. Attached Figure Description

[0027] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0028] Please see Figures 1 to 4 This utility model provides an improved vehicle-mounted motorcycle bracket, including a fixed frame 1, a lifting frame 2, a drive shaft 3, a drive wheel 4, and a steel wire rope 5. The lifting frame 2 is slidably mounted on the fixed frame 1. The drive shaft 3 is rotatably mounted on the fixed frame 1. The drive wheel 4 is fixed to the drive shaft 3. The steel wire rope 5 is wound around the drive wheel 4. The upper and lower ends of the steel wire rope 5 are respectively fixed to the upper and lower ends of the lifting frame 2. By driving the drive wheel 4 to rotate, the steel wire rope 5 pulls the lifting frame 2 up and down relative to the fixed frame 1. This improved vehicle-mounted motorcycle bracket ensures that the steel wire rope is released in an orderly manner during the lifting process, avoiding disordered release of the steel wire rope.

[0029] The improved vehicle-mounted motorcycle bracket of this utility model has the following beneficial effects:

[0030] I. Orderly Release of Wire Rope: The improved vehicle-mounted motorcycle bracket ensures the orderly release of the wire rope during lifting and lowering, preventing erratic release. This is thanks to the unique design where the two ends of the wire rope 5 are fixed to the upper and lower ends of the lifting frame 2, respectively, and the middle position is wound around the transmission wheel 4. This design allows the wire rope to maintain stable tension and movement trajectory during lifting and lowering, effectively preventing problems such as tangling and knotting, and ensuring the stability and reliability of the bracket's lifting and lowering.

[0031] II. Reduced Failure Rate: The orderly release design of the wire rope reduces the probability of failures caused by wire rope misalignment. In traditional brackets, misaligned wire rope release can lead to accelerated wire rope wear and damage to the drive pulleys. This invention effectively avoids these problems, reducing the frequency and cost of bracket maintenance.

[0032] III. Enhancing Overall Structural Strength: The fixed frame 1 provides a solid supporting foundation for the entire bracket system. The lifting frame 2 is slidably mounted on the fixed frame 1, and this structural design allows the bracket to maintain good stability when bearing the weight of the motorcycle. At the same time, the reasonable layout and connection method of the drive shaft 3, drive wheel 4, and wire rope 5 further enhances the structural strength of the entire bracket system, improving the load-bearing capacity and service life of the bracket.

[0033] IV. Parking support function: By driving the transmission wheel 4 to rotate, the steel wire rope 5 pulls the lifting frame 2 relative to the fixed frame 1 to rise and fall. The lifting frame 2 can actively descend to the ground, thus acting as a parking support leg to improve the stability of parking.

[0034] This utility model improves the vehicle-mounted motorcycle bracket by using a drive transmission wheel to drive a steel wire rope to achieve automated lifting of the lifting frame. It is simple and safe to operate and has a parking support function. Its unique steel wire rope fixing and winding design ensures the orderly release of the steel wire rope, enhances the overall structural stability, and reduces failures.

[0035] This utility model discloses an improved vehicle-mounted motorcycle bracket, including a sliding guide mechanism 6 mounted on a fixed frame 1 for mounting a lifting frame 2. Preferably, the sliding guide mechanism 6 includes a guide member 61 with a groove and sliding rollers 62. The guide member 61 is fixed to the fixed frame 1, and the lifting frame 2 is slidably mounted in the groove of the guide member 61. Two rotatable sliding rollers 62 are mounted at the upper and lower ends of the guide member 61 to clamp the two sides of the lifting frame 2. The sliding guide mechanism 6 of this utility model, with its guide member 61 fixed to the fixed frame 1 and the lifting frame 2 slidably mounted in its groove, and the upper and lower ends equipped with rotatable sliding rollers 62 clamping the two sides of the lifting frame 2, can effectively guide the lifting frame 2 to rise and fall smoothly along a predetermined trajectory, reduce shaking and jamming during the lifting process, and improve the overall operational stability and reliability of the bracket.

[0036] The wire rope 5 is wound in a single-layer spiral on the drive wheel 4. For example, the wire rope 5 is wound in a spiral shape on the drive wheel 4 one or more times, with each turn being a single layer of rope, and they cannot be stacked. This ensures that the rotation of the drive wheel 4 smoothly pulls the wire rope 5 to achieve the raising and lowering of the lifting frame 2.

[0037] In this embodiment, the improved vehicle-mounted motorcycle bracket of this utility model includes a lifting motor 7 mounted on a fixed frame 1 for driving the rotation of a drive shaft 3. The output shaft of the lifting motor 7 is connected to the drive shaft 3 to drive the drive shaft 3 to rotate. Two drive wheels 4 are provided, and the two drive wheels 4 are respectively fixed to both ends of the drive shaft 3. Two steel wire ropes 5 are provided, and the two steel wire ropes 5 are respectively wound around the two drive wheels 4. In addition, there can be one, three or more drive wheels 4. Correspondingly, there can be one, two or more steel wire ropes 5.

[0038] By setting up a lifting motor 7 to drive the transmission shaft 3 to rotate, automated lifting control of the vehicle-mounted motorcycle bracket is achieved. Compared with traditional manually operated brackets, this greatly improves operational efficiency and saves labor and time costs. Users only need to start the lifting motor 7, and the motor output shaft can quickly drive the transmission shaft 3 to rotate, easily completing the lifting and lowering action of the bracket, which is especially suitable for scenarios where motorcycles are frequently loaded and unloaded.

[0039] Two drive wheels 4 are fixed to the two ends of the drive shaft 3, and two steel wire ropes 5 are wound around the two drive wheels 4 respectively. This symmetrical transmission structure design ensures that the force on both sides of the bracket is even during the lifting process, avoiding the motorcycle tilting or shaking due to uneven force, thus providing a stable and reliable guarantee for loading and unloading the motorcycle, and effectively reducing the risk of vehicle damage caused by the instability of the bracket.

[0040] It is understandable that the rotation of drive shaft 3 can also be driven manually.

[0041] This utility model discloses an improved vehicle-mounted motorcycle bracket, including a locking mechanism (not shown) mounted on a fixed frame 1 for locking the height position of the lifting frame 2. The locking mechanism includes a rotating rod rotatably connected to the fixed frame 1, a hook disposed on the rotating rod, an adjusting handle disposed at one end of the rotating rod, and a return spring. The return spring is disposed between the adjusting handle and the fixed frame, and the hook engages the lifting frame 2. It is understood that the locking mechanism can also be a pin inserted between the fixed frame 1 and the lifting frame 2.

[0042] In this embodiment, the mounting bracket 1 includes two L-shaped brackets 11 for fixing to the vehicle body and a crossbeam 12 connecting the two L-shaped brackets 11. The lifting motor 7 is installed at the middle position of the crossbeam 12.

[0043] In this embodiment, the lifting frame 2 includes a frame 21 and a support frame 22 vertically fixed to the bottom of the frame 21 for placing the motorcycle. The two ends of the steel wire rope 5 are respectively fixed to the upper and lower beams of the frame 21.

[0044] In this embodiment, the lifting motor 7 is a reversible motor, and the lifting frame 2 is raised and lowered by controlling its forward and reverse rotation.

[0045] In summary, the improved vehicle-mounted motorcycle bracket of this utility model achieves automated lifting and lowering of the frame by driving the transmission wheel with a lifting motor and moving the steel wire rope. The operation is simple and safe. Its unique steel wire rope fixing and winding design ensures the orderly release of the steel wire rope, enhances the overall structural stability, and reduces failures.
