Description

Technical Field

[0001] This utility model relates to the field of RV technology, and in particular to an RV. Background Technology

[0002] The RV parking support structure is a device used to stabilize the RV when it is parked. Common types include manual support legs, electric support legs, and hydraulic support systems. RVs have two types of mobility: the main body has an engine that allows it to move on its own, and the RV does not have a generator and is towed by a tow truck. When the tow truck is not in use, it is separated from the front of the RV, and the front of the trailer is supported by the parking support structure.

[0003] An existing hand-cranked hydraulic mobile jack (publication number: CN218345059U) has at least the following drawbacks: In the aforementioned patent, the cylinder liner and connecting seat are fixed by threads, and the piston rod bottom integrates a traveling wheel, which facilitates quick installation and height adjustment of the trailer. At the same time, the design of the traveling wheel allows the trailer to move short distances without the need for tractor to tow. However, manually towing a motorhome requires considerable strength, which is difficult for some women with less strength to operate. In addition, when parking in some narrow spaces, it is necessary to observe the surrounding situation while manually pushing the vehicle, which is quite time-consuming and laborious, and inconvenient to use. Therefore, it is necessary to propose a motorhome to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a motorhome.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A motorhome includes a motorhome body, a manual hydraulic jack mounted on the top surface of the motorhome body, and a moving assembly for moving the motorhome body. The moving assembly includes: a fixed frame, which is fixedly mounted on the top surface of the motorhome body; a connector on one side of the fixed frame; a manual hydraulic jack fixedly mounted on one side of the connector; a universal caster bracket fixedly mounted on the bottom surface of the telescopic shaft of the manual hydraulic jack; a rotating wheel movably sleeved inside the universal caster bracket; a worm gear fixedly sleeved on the outer circular wall of the rotating shaft of the rotating wheel; two support plates fixedly mounted on one side of the universal caster bracket; a worm gear movably sleeved inside the support plates; the worm gear meshing with the worm gear; a drive motor fixedly mounted on one side of the universal caster bracket; one end of the drive shaft of the drive motor fixedly mounted to the worm gear; a fixed rod fixedly mounted on one side of the fixed frame; two control switches fixedly mounted on the outer circular wall of the fixed rod; and a first fixed plate fixedly mounted on one side of the rotating frame of the universal caster bracket.

[0006] As a further embodiment of this utility model, a hinge is fixedly installed on the top surface of the first fixed plate, a rotating handle is provided on one side of the first fixed plate, the rotating handle is connected to the first fixed plate by the hinge, and an elastic limiting plate is fixedly installed on one side of the first fixed plate, the elastic limiting plate is engaged with the bottom of the rotating handle.

[0007] As a further embodiment of this utility model, a plurality of threaded columns are fixedly installed on one side of the fixing frame, and a plurality of connecting holes are opened on one side of the connector. The connecting holes are movably sleeved with the threaded columns, and nuts are threadedly connected to the outer circular wall surface of the threaded columns.

[0008] As a further embodiment of this utility model, a storage battery and a PLC controller are fixedly installed on the inner top surface of the mounting bracket, and the storage battery, the control switch and the drive motor are all electrically connected to the PLC controller.

[0009] As a further embodiment of this utility model, a foot pedal plate is fixedly installed on one side of the universal caster frame, and a number of protruding strips are fixedly installed on the top surface of the foot pedal plate.

[0010] As a further embodiment of this utility model, two limiting cylinders are fixedly installed on one side of the connector, and a limiting rod is movably sleeved on the inner circular wall of the limiting cylinder, and the limiting rod is fixedly installed with the universal caster frame.

[0011] As a further embodiment of this utility model, a protective cover is fixedly installed on one side of the universal caster frame, and a protective cover is fixedly installed inside the fixed frame.

[0012] As a further embodiment of this utility model, a second fixing plate is fixedly installed on one side of the RV body, and a spring plate is fixedly installed on one side of the second fixing plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. By using the RV body, manual hydraulic jack, mounting bracket, connectors, universal caster frame, swivel wheels, and worm gear in combination, the RV body can be moved. The user's own weight is used as counterweight to increase the friction between the swivel wheels and the ground. The worm gear and worm wheel work together to rotate the wheels. Manually turning the handle rotates the universal caster frame to adjust the RV's direction. A control switch controls the RV's forward or backward movement. When the RV is disconnected from the towing vehicle, no manual pushing is required, saving energy. This is especially suitable for scenarios requiring high physical strength or precise positioning (such as parking in confined spaces). It balances convenience, safety, and versatility, making it easy to use and quite practical.

[0014] 2. The protective cover can protect components such as the worm gear and worm. When the swivel caster frame moves up and returns to its original position, and the RV body is towed by a towing vehicle, one side of the swivel caster frame rests against a spring plate. The spring plate can prevent the swivel caster frame from rotating on its own and avoid its violent shaking during driving. Pressing the elastic limit plate will prevent it from locking with the rotating handle. Rotating the rotating handle inward through the hinge can prevent it from protruding outward and affecting driving operation. Attached Figure Description

[0020] Reference Figures 1-4 A motorhome includes a motorhome body 1, a manual hydraulic jack 2 mounted on the top surface of the motorhome body 1, and a moving assembly for moving the motorhome body 1. The moving assembly includes a mounting frame 3, which is fixedly mounted on the top surface of the motorhome body 1. A connector 4 is provided on one side of the mounting frame 3, and the manual hydraulic jack 2 is fixedly mounted on one side of the connector 4. A universal caster frame 5 is fixedly mounted on the bottom surface of the telescopic shaft of the manual hydraulic jack 2. A rotating wheel 6 is movably sleeved inside the universal caster frame 5, and one end of the rotating shaft of the rotating wheel 6 is extended. The swivel caster 6 has a worm gear 7 fixedly sleeved on the outer circular wall of its rotating shaft. Two support plates 9 are fixedly installed on one side of the swivel caster 5. A worm 8 is movably sleeved inside the support plate 9. The worm gear 7 meshes with the worm 8. A drive motor 10 is fixedly installed on one side of the swivel caster 5. One end of the drive shaft of the drive motor 10 is fixedly installed with the worm 8. A fixing rod 13 is fixedly installed on one side of the fixing frame 3. Two control switches 14 are fixedly installed on the outer circular wall of the fixing rod 13. A first fixing plate 11 is fixedly installed on one side of the rotating frame of the swivel caster 5.

[0021] In use, hold the fixed rod 13 with your left hand and the rotating handle 12 with your right hand. Then, press the control switch 14 to start the drive motor 10, which drives the worm gear 8 to rotate. The worm gear 8 and the worm wheel 7 work together to convert the rotational motion into linear motion, which drives the rotating wheel 6 to rotate. Note that the speed of the drive motor 10 should increase linearly when it starts to prevent the rotating wheel 6 from rotating rapidly due to a sudden high speed. The same applies when it stops. While the rotating wheel 6 is moving the RV body 1, the user holds the rotating handle 12 to rotate the first fixed plate 11, the bottom movable part of the universal caster frame 5, and the rotating wheel 6 to achieve the steering operation of the RV body 1 and complete the position adjustment. After the adjustment is completed, the self-locking structure of the worm gear 8 and the worm wheel 7 will prevent the rotating wheel 6 from rotating on its own, making it very convenient to use.

[0022] In this embodiment, a hinge is fixedly installed on the top surface of the first fixed plate 11, and a rotating handle 12 is provided on one side of the first fixed plate 11. The rotating handle 12 is connected to the first fixed plate 11 by the hinge. An elastic limiting plate 21 is fixedly installed on one side of the first fixed plate 11. The elastic limiting plate 21 is engaged with the bottom of the rotating handle 12. A plurality of threaded posts 19 are fixedly installed on one side of the fixed frame 3. A plurality of connecting holes 23 are provided on one side of the connector 4. The connecting holes 23 are movably sleeved with the threaded posts 19. Nuts 20 are threadedly connected to the outer circular wall of the threaded posts 19. A battery 22 and a PLC controller are fixedly installed on the inner top surface of the fixed frame 3. The battery 22, the control switch 14, and the drive motor 10 are all electrically connected to the PLC controller.

[0023] When in use, press the elastic limit plate 21 to de-lock it from the rotary handle 12, and rotate the rotary handle 12 inward via the hinge to prevent it from protruding outward and affecting driving operation.

[0024] In this embodiment, a foot pedal plate 15 is fixedly installed on one side of the universal caster frame 5, and several protrusions 16 are fixedly installed on the top surface of the foot pedal plate 15. Two limiting cylinders 17 are fixedly installed on one side of the connector 4. A limiting rod 18 is movably sleeved on the inner circular wall of the limiting cylinder 17. The limiting rod 18 is fixedly installed with the universal caster frame 5. A protective cover 24 is fixedly installed on one side of the universal caster frame 5. A protective cover 27 is fixedly installed inside the fixing frame 3. A second fixing plate 25 is fixedly installed on one side of the RV body 1. A spring plate 26 is fixedly installed on one side of the second fixing plate 25.

[0025] During use, as the universal caster frame 5 moves downward, the limiting cylinder 17 supports the limiting rod 18, thereby limiting and supporting the movement path of the universal caster frame 5. The user can stand on the foot pedal 15 and increase the friction between the foot and the foot pedal 15 with the help of several protrusions 16. The protective cover 24 can protect the worm gear 7 and worm 8 and other components. When the universal caster frame 5 moves upward and resets, and the RV body 1 is towed by a towing vehicle, one side of the universal caster frame 5 abuts against the elastic spring plate 26. The spring plate 26 can prevent the universal caster frame 5 from rotating on its own and avoid its violent shaking during driving.

[0026] From the above description, it can be seen that the above-described embodiments of this utility model achieve the following technical effects: When the user needs to support the RV body 1, he can manually crank the handle of the manual hydraulic jack 2 to push the telescopic rod of the manual hydraulic jack 2 downward to move the universal caster frame 5. During the downward movement of the universal caster frame 5, the limiting cylinder 17 supports the limiting rod 18, thereby limiting and supporting the movement path of the universal caster frame 5. Afterward, the user can stand on the foot pedal 15 and increase the friction between the foot and the foot pedal 15 with the help of several protrusions 16, or sit on the RV body 1, holding the fixed rod 13 with the left hand and the rotating handle 12 with the right hand.

[0027] Next, press the control switch 14 to start the drive motor 10, which drives the worm gear 8 to rotate. The worm gear 8, in conjunction with the worm wheel 7, converts the rotational motion into linear motion, driving the rotating wheel 6 to rotate. It is important to note that the speed of the drive motor 10 should increase linearly when starting to prevent the rotating wheel 6 from rotating rapidly due to a sudden high speed. The same applies when stopping. While the rotating wheel 6 moves the RV body 1, the user holds the rotating handle 12 to rotate the first fixed plate 11, the bottom movable part of the universal caster frame 5, and the rotating wheel 6, thus achieving the steering operation of the RV body 1 and completing the position adjustment. After adjustment, the self-locking structure of the worm gear 8 and worm wheel 7 prevents the rotating wheel 6 from rotating on its own. It is very convenient to move, thus achieving the effect of moving the RV body 1. By using the user's own weight as a counterweight, the friction between the rotating wheel 6 and the ground is increased. The rotating wheel 6 is rotated by the cooperation of components such as the worm gear 8 and worm wheel 7. The direction of the RV body 1 is adjusted by manually turning the rotating handle 12 to drive the universal caster frame 5. The RV body 1 is controlled to move forward or backward by the control switch 14. When the RV body 1 is disconnected from the towing vehicle, there is no need for the user to push it manually, saving physical strength. It is especially suitable for scenarios that require high physical strength or precise positioning (such as parking in a small space). It takes into account convenience, safety and multi-functionality, making it easy to use and quite practical.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
