Description

Technical Field

[0001] This utility model relates to the field of parking support technology, specifically a parking support device for a towed caravan. Background Technology

[0002] Travel trailers can be towed by a family vehicle. The towing vehicle pulls the trailer along, allowing it to follow the vehicle and meet travel needs. Travel trailers provide sleeping, showering, kitchen, and toilet areas, thus improving the self-driving travel experience. When the travel trailer is parked in a designated location, the undercarriage support is usually deployed to ensure stability, providing a stable place for people to rest.

[0003] A search revealed a parking support device for a towed caravan with announcement number CN218141461U. The device specifically discloses a drive mechanism comprising a drive seat, a drive gear, a turntable, a threaded rod, a driven gear, a bearing seat, and a slide groove. The drive seat is fixed to the outer wall of a guide tube. A drive gear is disposed on the inner side of the drive seat, and one side of the drive gear is connected to the turntable via a rotating rod. The upper end of the threaded rod is connected to the inner side of the drive seat via a bearing. A driven gear is fixed to the outside of one end of the threaded rod extending into the drive seat. Both the drive gear and the driven gear are bevel gears, and they are meshed. The conduit is connected to a bearing seat fixed below the outer wall of the drive seat. The bearing seat is connected to the lower end of the threaded rod. A groove is opened on the side of the conduit near the threaded rod. A connecting block that passes through the groove is fixed on one side of the support column. The connecting block and the threaded rod are threaded together. When parking a towed caravan, it is necessary to operate the support devices around the bottom of the caravan to limit its position. However, the threaded rod described in the document is exposed on the outside. When the caravan is towed, dust and dirt will inevitably adhere to the surface of the threaded rod, making it inconvenient to adjust the parking support device later.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, this utility model provides a parking support device for towed caravans, which has the following advantages:

[0022] This utility model allows the support frame to be retracted and extended via a positioning groove, enabling the parking support component to be retracted into its interior. The adjustment mechanism allows the support frame to be rotated at an angle, facilitating subsequent support of the RV. When the support frame is retracted or extended, the dustproof cover on the outside of the support body can cover the adjustment mechanism, preventing dirt and other contaminants from falling into the adjustment mechanism during RV towing.

[0023] In this invention, when support is required, the angle of the support body can be adjusted through the adjustment mechanism to keep the support body vertical to the RV. Then, the electromagnet assembly is energized. When the electromagnet assembly is energized, it generates magnetic force, which pulls the extension collar downward, allowing the connecting protrusion and connecting groove to be connected. The connecting shaft and adjusting screw can then be rotated and adjusted through the drive mechanism, which pushes the support sleeve downward to support the RV. Since the adjusting screw and support sleeve are both located inside the support body, the cleanliness of the support assembly can be ensured, preventing dust and dirt from adhering to its surface and affecting subsequent adjustments.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example

[0034] like Figure 1-7 As shown, an embodiment of this utility model provides a parking support device for a towed caravan, including a caravan 1 and a towing assembly 2 fixed to one side of the caravan 1, and further including:

[0035] The positioning groove 3 is symmetrically opened on the lower end face of the RV 1. A support frame 4 is provided on the inner side of the positioning groove 3. A positioning shaft 5 is fixed at one end of the support frame 4, and the left and right ends of the positioning shaft 5 are rotatably connected to the inner side of the positioning groove 3.

[0036] An adjustment mechanism is set on one side of the support frame 4 and located inside the positioning groove 3. It is used to adjust the angle of the support frame 4. The adjustment mechanism includes a worm gear 6, a worm 7 and a servo motor 8. The worm gear 6 is fixed at the center of the outer surface of the positioning shaft 5. The worm 7 is meshed with the upper end of the worm gear 6. The servo motor 8 is fixed on the inner side of the RV 1 and located at one end of the positioning groove 3. The output end of the servo motor 8 is fixed to one end of the worm 7. The servo motor 8 can drive the worm 7 to rotate. When the worm 7 rotates, it can cooperate with the worm gear 6 to rotate and adjust the positioning shaft 5, thereby enabling the support frame 4 to be unfolded and retracted. Since the adjustment mechanism is realized through the worm gear, it has a self-locking effect, which can limit the support frame 4 during unfolding and retraction, and can prevent the support frame 4 from falling off when the RV is towed.

[0037] The support body 9 is fixed inside the support frame 4. A connecting shaft 10 is rotatably connected inside the support body 9. An adjusting screw 11 is fixed at the lower end of the connecting shaft 10 and is located in the center of the support body 9. A dust cover 901 is fixed on one side of the support body 9. When the support body 9 rotates 90°, the dust cover 901 covers the outside of the adjusting mechanism. The adjusting mechanism can adjust the support frame 4 and the support body 9. When the support frame 4 and the adjusting mechanism are horizontal, the dust cover 901 can completely cover the outside of the adjusting mechanism, which can prevent dirt and other substances from falling into the adjusting mechanism when the RV 1 is towed.

[0038] The support sleeve 12 is threaded onto the outer surface of the adjusting screw 11, and the support sleeve 12 can slide up and down along the inside of the support body 9 for adjustment; the upper end of the connecting shaft 10 is provided with a connecting groove 13, and the cross-section of the connecting groove 13 is set in a "+" shape. The connecting groove 13 can be conveniently connected to the connecting protrusion 18 in the future, which can facilitate the subsequent lifting and lowering of the support sleeve 12.

[0039] The drive mechanism, located inside the RV 1 and within the positioning groove 3, drives the connecting shaft 10 to rotate. The drive mechanism includes a drive motor 14, a support plate 15, an extension rod 16, an extension collar 17, and a connecting protrusion 18. The drive motor 14 is fixed inside the positioning groove 3, the support plate 15 is fixed to the output end of the drive motor 14, the extension rod 16 is fixed to the center of the lower end face of the support plate 15, and the outer surface of the extension rod 16 is provided with multiple sets of protruding sliders. The extension collar 17 is fitted onto the outer surface of the extension rod 16, and the extension collar 17 has a horizontal... The cross-section is set in an "I" shape. The connecting protrusion 18 is fixed on the lower end face of the extension collar 17, and the connecting protrusion 18 and the connecting groove 13 are on the same vertical center line. The drive motor 14 can drive the bearing plate 15 to rotate. The outer side of the extension rod 16 is provided with a protruding slider, which can be engaged with the extension collar 17. When the bearing plate 15 rotates, the extension rod 16 can drive the extension collar 17 to rotate accordingly. At the same time, because the protruding slider can be adjusted up and down by the extension collar 17, the extension rod 16 can always drive the extension collar 17 to rotate.

[0040] The left and right ends of the bearing plate 15 are fixed with limiting slide rods 19. The lower end of the limiting slide rod 19 is fixed with an electromagnet assembly 20. The outer surface of the limiting slide rod 19 is sleeved with a return spring 21. One end of the return spring 21 is in contact with the electromagnet assembly 20, and the other end is in contact with one side of the extension collar 17. The limiting slide rod 19 can limit the position of the extension collar 17, which can prevent the extension collar 17 from shifting or shaking. Then, when the electromagnet assembly 20 is energized, it can generate magnetic force, which can pull the extension collar 17 downward, so that the connecting protrusion 18 at the lower end of the extension collar 17 can be engaged with the connecting groove 13 for subsequent adjustment.

[0041] When support is needed, the servo motor 8 can drive the worm gear 7 to rotate. When the worm gear 7 rotates, it can cooperate with the worm wheel 6 to rotate and adjust the positioning shaft 5, thereby enabling the support frame 4 to be unfolded and retracted, and the angle of the support body 9 to be adjusted so that the support body 9 and the RV 1 remain vertical. Then, the electromagnet assembly 20 is energized. When the electromagnet assembly 20 is energized, it can generate magnetic force, which can pull the extension collar 17 downward, so that the connecting protrusion 18 and the connecting groove 13 can be connected.

[0042] Then, the drive motor 14 is turned on. The drive motor 14 can drive the support plate 15 to rotate. The outer side of the extension rod 16 is provided with a protruding slider, which can be engaged with the extension collar 17. When the support plate 15 rotates, the extension rod 16 can drive the extension collar 17 to rotate accordingly. At the same time, the protruding slider can also limit the position of the extension collar 17 to prevent it from deviating. Then, because the protruding slider can adjust the extension collar 17 up and down, the extension rod 16 can always drive the extension collar 17 to rotate. In turn, the adjusting screw 11 can be driven to rotate through the connecting shaft 10. When the adjusting screw 11 rotates, the support sleeve 12 threaded to it can be pushed down to support the RV.

[0043] Finally, if a reset is required, the support sleeve 12 can be retracted into the support body 9 by flipping the drive motor 14. Since the adjusting screw 11 and the support sleeve 12 are both located inside the support body 9, the cleanliness of the support assembly can be ensured, and dust and dirt can be prevented from adhering to its surface and affecting subsequent work adjustments. When the electromagnet assembly 20 is turned off, the extension collar 17 can be reset by the reset spring 21. Then, the support body 9 can be retracted into the positioning groove 3 by adjusting the mechanism.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
