Description

Technical Field

[0001] This invention relates to the field of vehicle cover technology, specifically to a towable caravan with an electrically tilting vehicle cover. Background Technology

[0002] Car hatches are typically made of aluminum alloy, fiberglass reinforced plastic, or other lightweight composite materials. Lightweight construction not only improves fuel economy but also reduces the overall structural load. The hatch design must meet collision safety standards to ensure occupant protection and minimize injury in the event of an accident.

[0003] Patent publication number CN104210414B relates to the field of vehicle body cover technology, including side walls on both sides of the vehicle body and end walls at both ends of the vehicle body. Its key feature is that a support plate is hinged to the top of each side wall, the top edge of which is an inclined edge. The lower end of the inclined edge is located on the top surface of the side wall at one end of the vehicle body, and the higher end is located on the top of the side wall at the other end of the vehicle body. It also includes a vehicle body cover, one end of which is hinged to the end wall at the lower end of the inclined edge of the support plate. This support-cover vehicle body structure is reasonable and easy to operate, and can be widely used in the production of various RVs.

[0004] The aforementioned patented canopy-type trailer structure is reasonable and easy to operate, and can be widely used in various RV production. While trailer RVs with electrically tilting canopies can open and close the roof via an electric push rod, providing a viewing platform, their mechanical locking structure has significant defects. These older devices often use simple pins or hooks for manual locking. Once the viewing platform is fully extended, they cannot form a reliable rigid self-locking limit, relying solely on a motor brake or simple latches to maintain the state. If subjected to strong winds or external forces such as people leaning against them, the canopy is prone to shaking or even accidental closure, posing a serious safety hazard. Furthermore, the unlocking and drive mechanisms during retraction lack a linkage design; the push rod and locking components operate independently, leading to frequent mechanical interference. Long-term hard friction between components not only produces sharp noises but also causes wear on the pin holes and deformation of the latch, reducing locking reliability and requiring frequent manual adjustments and replacements, significantly shortening the system's lifespan. In addition, when the vehicle is driving on bumpy roads, the gap between the unlocked roof structure and the protective panel will generate continuous collision and vibration noise, which will seriously affect the ride comfort. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a trailer caravan with an electrically tilting roof, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a towable caravan with an electrically tilting roof, comprising a vehicle body, and the towable caravan further comprising:

[0007] A mounting bracket is fixedly installed on the top of the vehicle body, and a protective plate is rotatably installed on the inner wall of the mounting bracket.

[0008] A push rod is slidably mounted on the inner wall of the vehicle body, and a top plate is fixedly mounted on the top of the push rod.

[0009] A protective device is installed on the outer wall of the guard plate to prevent the guard plate from rotating when the top plate is raised;

[0010] The protective device can switch between a first state and a second state. In the first state, the top plate will be raised and the guard plate will rotate to protect the top of the vehicle body. In the second state, the top plate will be retracted and the guard plate will rotate back to its original position to cover the top of the vehicle body.

[0011] A support device used to strengthen the support of the guard plate is installed on the outer wall of the guard plate;

[0012] A clamping device for securing the top plate to the guard plate is installed on the outer wall of the top plate.

[0013] According to the above technical solution, the protection device includes:

[0014] A pressure plate is fixedly installed on the outer wall of the guard plate shaft, and a fixing plate is also fixedly installed at the bottom of the guard plate shaft;

[0015] The insert plate is slidably mounted on the top of the vehicle body.

[0016] The fixing plate has a slot at its bottom, the insert plate contacts the inner wall of the fixing plate, and a spring is provided between the insert plate and the vehicle body.

[0017] The technical effect of adopting the above-mentioned further solution is that when the guard plate rotates, it will drive the fixed plate to rotate, and the rotation of the fixed plate will drive the slot to move. When the position of the slot coincides with the insertion plate, the insertion plate will move into the slot to limit the fixed plate.

[0018] According to the above technical solution, the protection device further includes:

[0019] A pressing rod is slidably installed on the inner wall of the fixed frame, and the pressing rod is fixedly connected to the insert plate;

[0020] A sliding rod is slidably mounted on the inner wall of the pressing rod, and a push block is fixedly mounted on the inner wall of the fixed frame.

[0021] The technical effect of adopting the above-mentioned further solution is that when the sliding rod moves downward, it will contact the inclined surface of the push block, and the push block will push the sliding rod to disengage it from the push rod.

[0022] According to the above technical solution, the fixing device further includes:

[0023] A groove is formed on the side of the sliding rod near the push block, and the side of the push block near the groove is set as an inclined surface;

[0024] A square groove is formed on the side of the push rod near the sliding rod, and the side of the sliding rod near the push rod is set as an inclined surface.

[0025] The technical effect of adopting the above-mentioned further solution is that the sliding rod moves downward through the square groove, and the downward movement of the sliding rod will cause the insert plate to move downward.

[0026] According to the above technical solution, the support device includes:

[0027] A slider is slidably mounted on the outer wall of the fixed frame, and a telescopic key is slidably mounted on the inner wall of the slider.

[0028] A fixed housing is fixedly installed on the side of the fixed frame near the slider, and a telescopic key is slidably installed on the inner wall of the fixed housing;

[0029] The slider has a sliding groove on the side near the telescopic key two, and the telescopic key two contacts the inner wall of the slider.

[0030] The technical effect of adopting the above-mentioned further solution is that when telescopic key one moves downward, it will contact telescopic key two, which will then contact the inner wall of the slider. When the fixing plate disengages from telescopic key one, telescopic key two will limit the slider.

[0031] According to the above technical solution, the support device further includes:

[0032] The rotating block is rotatably mounted on the side of the fixed frame near the slider;

[0033] The second telescopic rod has one end rotatably connected to the slider, and the other end rotatably connected to the rotating block.

[0034] The technical effect of adopting the above-mentioned further solution is that the movement of the slider drives the movement of the telescopic rod two, and the movement of the telescopic rod two will drive the rotating block to rotate.

[0035] According to the above technical solution, the support device further includes:

[0036] A fixing block is fixedly installed on the side of the guard plate near the slider;

[0037] Sliding block two is slidably mounted on the side of the fixed frame near the slider;

[0038] One telescopic rod is rotatably connected at one end to a sliding block two, and the other end of the telescopic rod is rotatably connected to a rotating block;

[0039] The fixed block and the sliding block 2 are respectively set as inclined surfaces on the side that are close to each other, the telescopic key 1 is set as inclined surfaces on the side that is close to the insert plate, the telescopic key 1 and the slider are provided with spring 2, and the fixed shell and the telescopic key 2 are provided with spring 3.

[0040] The technical effect of adopting the above-mentioned further solution is that when the telescopic rod moves, it will push the sliding block to move upward. When the sliding block moves upward, it will contact the fixed block, and the sliding block will strengthen the support effect of the guard plate.

[0041] According to the above technical solution, the clamping device includes:

[0042] A sliding plate is provided at the bottom of the top plate, and a pressure block is fixedly installed on the top of the sliding plate. A sliding groove is provided on the top of the top plate.

[0043] The limiting block is slidably installed on the inner wall of the sliding groove.

[0044] The technical effect of adopting the above-mentioned further solution is that when the top plate moves downward, the sliding plate will push the pressure block to move upward. When the pressure block moves upward, it will contact the inclined surface of the limiting block, and then the pressure block will push the limiting block to lock the inner wall of the slot.

[0045] According to the above technical solution, the clamping device further includes:

[0046] The clamping plate is slidably installed on the inner wall of the limiting block;

[0047] Among them, a spring four is provided between the top plate and the sliding plate, a spring five is provided between the pressing plate and the limiting block, the side of the pressing block and the limiting block that are close to each other is set as an inclined surface, a slot is opened on the side of the guard plate close to the pressing plate, and a clamping groove is opened on the inner wall of the slot.

[0048] The technical effect of adopting the above-mentioned further solution is that the lateral wedging of the side wall of the slot by the limiting block and the longitudinal engagement of the clamping plate with the clamping slot completely eliminate the gap between the guard plate and the top plate.

[0049] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0050] 1. In this invention, after the viewing platform is fully deployed, the insert plate can automatically insert into the slot of the fixed plate to form a rigid limit, effectively preventing the protective plate from loosening or closing due to external force or accident, ensuring the structural stability and personnel safety during high-altitude viewing. Through the contact arrangement of the push block and the sliding rod, it is ensured that the sliding rod and the push rod can be effectively disengaged, and at the same time, the contact between the fixed plate and the insert plate is released, avoiding wear caused by direct friction and extending the service life of the system components.

[0051] 2. In this invention, the reinforcement of support strength is automatically triggered by the rotation of the guard plate, ensuring that the guard plate provides additional support when rotation protection is required. The rigid mechanical interlock between the telescopic key two and the inner wall of the slider ensures that the slider can never reset itself in the supported state, providing an extremely stable support foundation for the unfolded guard plate. Furthermore, the rotational force is transformed into a supporting force on the sliding block through the rotating block and the telescopic rod one, which can effectively strengthen the guard plate's resistance to pressure or impact from above.

[0052] 3. In this invention, the lateral wedging of the side wall of the slot by the limiting block and the longitudinal engagement of the clamping plate with the clamping groove completely eliminate the gap between the guard plate and the top plate. The two parts are rigidly connected by the locking force, which fundamentally eliminates relative movement and thus completely eliminates the collision and abnormal noise between the two.

[0063] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0064] Please see Figures 1-8 One embodiment of the present invention is a towable caravan with an electrically tilting roof, comprising a vehicle body 1, a fixing frame 2, a protective plate 3, a push rod 4, and a roof plate 5.

[0065] The mounting bracket 2 is fixedly installed on the top of the vehicle body 1. A protective plate 3 is rotatably installed on the inner wall of the mounting bracket 2. The push rod 4 is slidably installed on the inner wall of the vehicle body 1. A top plate 5 is fixedly installed on the top of the push rod 4.

[0066] A protective device is installed on the outer wall of the guard plate 3 to prevent the guard plate 3 from rotating when the top plate 5 is raised.

[0067] The protective device can switch between a first state and a second state. In the first state, the top plate 5 will be raised and the guard plate 3 will rotate to protect the top of the vehicle body 1. In the second state, the top plate 5 will be retracted and the guard plate 3 will rotate back to its original position to cover the top of the vehicle body 1.

[0068] A support device for strengthening the support of the guard plate 3 is installed on the outer wall of the guard plate 3.

[0069] A clamping device for clamping the top plate 5 and the guard plate 3 is provided on the outer wall of the top plate 5.

[0070] In this embodiment, the above-mentioned protective device includes a plug plate 6, a pressure plate 7, a fixing plate 8, a sliding rod 9, a push block 10, and a pressing rod 11.

[0071] The pressure plate 7 is fixedly installed on the outer wall of the shaft of the guard plate 3. The bottom of the shaft of the guard plate 3 is also fixedly installed with a fixing plate 8 and a plug plate 6, which are slidably installed on the top of the vehicle body 1.

[0072] The bottom of the fixing plate 8 has a slot, the insert plate 6 contacts the inner wall of the fixing plate 8, and a spring is provided between the insert plate 6 and the vehicle body 1. The spring is provided to drive the insert plate 6 to move upward.

[0073] It should also be noted that the pressing rod 11 is slidably installed on the inner wall of the fixed frame 2, and the pressing rod 11 is fixedly connected to the insert plate 6. The sliding rod 9 is slidably installed on the inner wall of the pressing rod 11. The push block 10 is fixedly installed on the inner wall of the fixed frame 2. The sliding groove is opened on the side of the sliding rod 9 near the push block 10. The side of the push block 10 near the sliding groove is set as an inclined surface. The inclined surface of the push block 10 is to push the sliding rod 9 to move in the direction of the pressing rod 11. The square groove is opened on the side of the push rod 4 near the sliding rod 9. The side of the sliding rod 9 near the push rod 4 is set as an inclined surface. The inclined surface of the sliding rod 9 is to facilitate pushing the sliding rod 9 to move in the direction of the pressing rod 11 when the push rod 4 moves.

[0074] In this embodiment, when a large viewing space needs to be created on the top of the vehicle body 1, the push rod 4 is moved upward by the controller built into the vehicle body 1. The upward movement of the push rod 4 pushes the top plate 5 upward. When the top plate 5 moves upward, it pushes the guard plate 3 to rotate, so that after the space above is formed, the guard plate 3 can block and protect the surroundings. When the guard plate 3 rotates, it drives the fixing plate 8 to rotate. The rotation of the fixing plate 8 drives the slot to move. When the position of the slot coincides with the insertion plate 6, the insertion plate 6 will move inward into the slot to limit the fixing plate 8. When the fixing plate 8 is limited, the guard plate 3 will also be limited and cannot rotate. When the push rod 4 drives the top plate 5 to descend, the movement of the push rod 4 will drive the square groove to move. When the position of the square groove coincides with the sliding rod 9, the sliding rod 9 will move inward into the square groove. Then, the downward movement of the push rod 4 will drive the sliding rod 9 to move. Moving downwards will cause the pressing rod 11 to move, and the movement of the pressing rod 11 will cause the insert plate 6 to move downwards, releasing the restriction on the fixed plate 8. When the top plate 5 moves downwards, it will contact the pressure plate 7. When the restriction on the guard plate 3 is released, the downward movement of the top plate 5 will push the pressure plate 7 to move. The movement of the pressure plate 7 will cause the guard plate 3 to rotate, so that the guard plate 3 can be placed on top of the top plate 5 after the top plate 5 has descended. After the viewing platform is fully unfolded, the insert plate 6 can automatically insert into the slot of the fixed plate 8 to form a rigid restriction, effectively preventing the guard plate 3 from loosening or closing due to external force or accidents, ensuring the structural stability and personnel safety during high-altitude viewing. Through the contact arrangement of the push block 10 and the sliding rod 9, it is ensured that the sliding rod 9 and the push rod 4 can be effectively disengaged, and the contact between the fixed plate 8 and the insert plate 6 is also released, avoiding wear caused by direct friction and extending the service life of the system components.

[0075] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the trailer caravan with an electrically tilting roof further includes a support device and a clamping device.

[0076] In this embodiment, the support device includes a fixed block 21, a sliding block 22, a rotating block 23, a first telescopic rod 24, a second telescopic rod 25, a slider 26, a first telescopic key 27, a fixed shell 28, and a second telescopic key 29.

[0077] The slider 26 is slidably mounted on the outer wall of the fixed frame 2. A telescopic key 27 is slidably mounted on the inner wall of the slider 26. A fixed shell 28 is fixedly mounted on the side of the fixed frame 2 near the slider 26. A telescopic key 29 is slidably mounted on the inner wall of the fixed shell 28. A sliding groove is opened on the side of the slider 26 near the telescopic key 29. The telescopic key 29 contacts the inner wall of the slider 26. A rotating block 23 is rotatably mounted on the side of the fixed frame 2 near the slider 26. One end of the telescopic rod 25 is rotatably connected to the slider 26. The other end of the telescopic rod 25 is rotatably connected to the rotating block 23. A fixed block 21 is fixedly mounted on the side of the guard plate 3 near the slider 26. Two sliding blocks 22 are slidably mounted on the side of the fixed frame 2 near the slider 26. One end of the telescopic rod 24 is rotatably connected to the two sliding blocks 22. The other end of the telescopic rod 24 is rotatably connected to the rotating block 23.

[0078] Among them, the side of the fixed block 21 and the two sliding blocks 22 that are close to each other is set as an inclined surface. The fixed block 21 is set as an inclined surface to facilitate the two sliding blocks 22 to apply pressure to the fixed block 21. The side of the telescopic key 27 that is close to the insert plate 6 is set as an inclined surface. The telescopic key 27 is set as an inclined surface to avoid obstructing the rotation of the fixed plate 8. A second spring is set between the telescopic key 27 and the slider 26. The second spring is set to drive the telescopic key 27 to reset. A third spring is set between the fixed shell 28 and the telescopic key 29. The third spring is set to drive the telescopic key 29 to reset.

[0079] In this embodiment, the clamping device includes a sliding plate 31, a pressure block 32, a limiting block 33, and a clamping plate 34.

[0080] Among them, the sliding plate 31 is set at the bottom of the top plate 5, the pressure block 32 is fixedly installed on the top of the sliding plate 31, the top of the top plate 5 is provided with a sliding groove, the limiting block 33 is slidably installed on the inner wall of the sliding groove, and the pressing plate 34 is slidably installed on the inner wall of the limiting block 33.

[0081] It should also be noted that a spring four is provided between the top plate 5 and the sliding plate 31. The purpose of the spring four is to drive the sliding plate 31 to reset. A spring five is provided between the pressing plate 34 and the limiting block 33. The purpose of the spring five is to drive the pressing plate 34 to move downward. The side of the pressing block 32 and the limiting block 33 that are close to each other is set as an inclined surface. A slot is opened on the side of the guard plate 3 that is close to the pressing plate 34. A locking groove is opened on the inner wall of the slot.

[0082] In this embodiment, during operation: when the top plate 5 moves upward and pushes the guard plate 3 to rotate, the rotation of the guard plate 3 will cause the fixed plate 8 to move. The fixed plate 8 will then contact the telescopic key 27, which will push the telescopic key 27 downward. The downward movement of the telescopic key 27 will then contact the telescopic key 29, which will then contact the inner wall of the slider 26. When the fixed plate 8 disengages from the telescopic key 27, the telescopic key 29 will limit the slider 26, preventing it from resetting. The downward movement of the slider 26 will pull the telescopic rod 25, which will then cause the rotating block 23 to rotate. The rotation of the rotating block 23 will then push the telescopic rod 24, which will then push the sliding block 22 upward. The upward movement of the sliding block 22 will then contact the fixed block 21, thus reinforcing the guard plate 3. The support effect is such that when the guard plate 3 rotates to its original position, it will contact the inclined surface of the telescopic key 27. Then the fixed plate 8 will push the telescopic key 27 to move towards the telescopic key 29. The telescopic key 29 will be pushed to its original position by the telescopic key 27, releasing the limit on the slider 26. The slider 26 can then move to its original position. The strengthening of the support strength is automatically triggered by the rotation of the guard plate 3, ensuring that the guard plate 3 provides additional support when rotation protection is required. The rigid mechanical interlock between the telescopic key 29 and the inner wall of the slider 26 ensures that the slider 26 can never reset itself in the supported state, providing an extremely stable support foundation for the unfolded guard plate 3. Furthermore, the rotational force is transformed into a supporting force on the sliding block 22 through the rotating block 23 and the telescopic rod 24, which can effectively strengthen the guard plate 3's resistance to pressure or impact from above.

[0083] When the top plate 5 is retracted, the guard plate 3 rotates towards the top of the top plate 5. As the guard plate 3 rotates, it moves the slot, causing the limiting block 33 and the pressing plate 34 to contact the inner wall of the slot. When the top plate 5 moves downwards, it pushes the sliding plate 31 downwards. The sliding plate 31 then contacts the top of the vehicle body 1, and the vehicle body 1 applies a reverse force to the sliding plate 31. As the top plate 5 moves downwards, the sliding plate 31 pushes the pressing block 32 upwards. The pressing block 32 then contacts the inclined surface of the limiting block 33, causing the limiting block 33 to clamp against the inner wall of the slot. The movement of the limiting block 33 further pushes the pressing plate 34 to move, thus clamping the slot. When plate 34 moves, it will come into contact with the inner wall of the clamping groove. Then, the clamping plate 34 will move into the clamping groove. When the clamping plate 34 moves, the spring 5 between the clamping plate 34 and the limiting block 33 will apply a downward pulling force to the clamping plate 34, pulling the clamping plate 34 to clamp the clamping groove. This prevents the guard plate 3 from colliding with the top plate 5 due to road bumps during the movement. Through the lateral wedging of the side wall of the clamping groove by the limiting block 33 and the longitudinal engagement of the clamping plate 34 with the clamping groove, the movement gap between the guard plate 3 and the top plate 5 is completely eliminated. The locking force rigidly connects the two parts, fundamentally eliminating relative movement and thus completely eliminating the collision and abnormal noise between them.
