Description

Technical Field

[0001] This utility model relates to the field of RV roof technology, specifically to an RV roof lifting and balancing stabilizing device. Background Technology

[0002] As the RV market continues to develop, consumers are demanding higher and higher levels of comfort and functionality from RVs. The lift-up design of the RV roof can effectively increase the flexibility of the interior space and meet the needs of users in different scenarios.

[0003] Currently, most RV roof lifting devices on the market suffer from problems such as imbalance and swaying after lifting. Their strength is low, which not only affects the convenience and comfort of use, but may also pose safety hazards.

[0004] Therefore, a RV roof lifting and balancing stabilization device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a RV roof lifting and balancing stabilization device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A motorhome roof lifting and balancing stabilization device includes a base, a roof frame, and a roof installed on the roof frame. A shear-type lifting assembly is provided between the base and the roof frame. Flexible barriers are fixedly installed on the inner walls of the base and the roof frame. A reset assembly is provided on the base, and a pull rope is connected to the bottom surface of the roof frame for the movable part of the reset assembly. An electromagnetic locking assembly is provided on the reset assembly. When the base and the roof frame are unfolded, the electromagnetic locking assembly fixes the movable part of the reset assembly, and the pull rope is used to increase the strength of the motorhome roof.

[0008] Furthermore, the shear-type lifting assembly includes a first frame embedded in the top surface of the base, and a motor is fixedly installed on one side wall of the first frame. A bidirectional threaded rod is fixedly connected to the output end of the motor. A first slider is threadedly sleeved on the surface of the bidirectional threaded rod. A second frame is embedded in the bottom surface of the top frame, and a first guide rod is fixedly installed on the inner wall of the second frame. A second slider is slidably installed on the first guide rod. A shear frame is hinged to the top surface of the first slider and the bottom surface of the second slider.

[0009] Furthermore, the reset assembly includes a third frame embedded in the top surface of the base, with second guide rods fixedly installed on the inner walls of both sides of the third frame. A movable block, which is the movable part, is slidably installed inside the third frame and on the surface of the second guide rod. A first spring is sleeved on the surface of the second guide rod, and the two ends of the first spring are fixed to the movable block and the end face of the base, respectively.

[0010] Furthermore, the electromagnetic locking assembly includes a lock hole formed on the surface of the third frame, an electromagnet is fixedly installed on the inner wall of the lock hole, an armature is slidably installed in the lock hole, a locking pin is fixedly installed on the end face of the armature, the locking pin is movably inserted into the movable block, and a second spring is provided between the armature and the electromagnet.

[0011] Furthermore, when the top frame and flexible enclosure are deployed, the two sets of movable blocks located in the third frame are brought closer to each other by pulling ropes. When the top frame and flexible enclosure are fully deployed, the movable blocks move to the maximum position of the third frame.

[0012] Furthermore, when the top frame and flexible enclosure are fully extended, the locking pins that are movably inserted into the movable block are correspondingly set with the lock holes on the surface of the third frame. The locking pins are machined and inserted into the lock holes to limit the movement of the movable block.

[0013] The beneficial effects of this utility model are as follows:

[0014] The shear-type lifting assembly allows the base and top frame to unfold. As the top frame moves vertically upward, the pull rope pulls the movable part of its reset assembly closer together. When the top frame and flexible enclosure are fully unfolded, the electromagnetic locking assembly fixes the movable part of the reset assembly, ensuring that the top frame remains in the unfolded state. At the same time, the presence of the pull rope enhances the overall strength of the RV roof, reduces excessive deformation or shaking of the roof due to external forces during use, and increases its structural strength.

[0024] like Figures 1 to 4 As shown, a RV roof lifting and balancing stabilizing device includes a base 1, a roof frame 2, and a roof 21 mounted on the roof frame 2. A shear-type lifting assembly 3 is provided between the base 1 and the roof frame 2. Figure 1 and Figure 3 As shown, specifically, the shear-type lifting assembly 3 includes a first frame 301 embedded in the top surface of the base 1, and a motor 302 is fixedly installed on one side wall of the first frame 301. A bidirectional threaded rod 303 is fixedly connected to the output end of the motor 302. A first slider 304 is threadedly sleeved on the surface of the bidirectional threaded rod 303. A second frame 305 is embedded in the bottom surface of the top frame 2, and a first guide rod 306 is fixedly installed on the inner wall of the second frame 305. A second slider 307 is slidably installed on the first guide rod 306. A shear frame 308 is hingedly installed on the top surface of the first slider 304 and the bottom surface of the second slider 307.

[0025] More specifically, the motor 302 drives the bidirectional threaded rod 303 to rotate, causing the two sets of first sliders 304 to move closer or further apart along the bidirectional threaded rod 303. This causes the shearing frame 308 to undergo shearing motion, prompting the roof frame 2 to lift and lower. During this process, the second slider 307 slides along the first guide rod 306 to ensure the stability of the roof frame 2 during lifting and lowering, preventing the roof frame 2 from tilting or jamming during the lifting and lowering process, thereby achieving the smooth lifting and lowering of the RV roof.

[0026] Flexible barriers 4 are fixedly installed on the inner walls of the base 1 and the top frame 2. A reset assembly 5 is provided on the base 1, and a pull rope 7 is connected to the movable part of the reset assembly 5 and the bottom surface of the top frame 2; Figure 1 and Figure 2 As shown, specifically, the reset assembly 5 includes a third frame 501 embedded in the top surface of the base 1. Second guide rods 502 are fixedly installed on the inner walls of both sides of the third frame 501. A movable block 503, which is the movable part, is slidably installed inside the third frame 501 and on the surface of the second guide rods 502. A first spring 504 is sleeved on the surface of the second guide rods 502. The two ends of the first spring 504 are fixed to the movable block 503 and the end face of the base 1, respectively.

[0027] More specifically, when the roof frame 2 is raised or lowered, the pull rope 7 applies a pulling force to the movable block 503, which slides within the third frame 501, while simultaneously stretching the first spring 504. When reset is required, as the roof frame 2 descends, the elastic potential energy of the first spring 504 pulls the movable block 503 back to its initial position, thus improving the safety and stability of the RV roof retraction process.

[0028] In some practical applications, when the top frame 2 and the flexible enclosure 4 are deployed, the two sets of movable blocks 503 located in the third frame 501 are brought closer to each other by the pull rope 7. When the top frame 2 and the flexible enclosure 4 are fully deployed, the movable blocks 503 reach the maximum position of the third frame 501.

[0029] More specifically, as the top frame 2 and the flexible enclosure 4 are fully deployed, the movable block 503 moves to its maximum position within the third frame 501. Through the pulling action of the pull rope 7, the stability of the roof 21 after deployment is further enhanced, preventing the roof 21 from shaking or deforming due to external wind or vehicle swaying during use, thus improving the reliability of the RV roof during use.

[0030] Furthermore, the reset assembly 5 is equipped with an electromagnetic locking assembly 6. When the base 1 and the top frame 2 are unfolded, the electromagnetic locking assembly 6 secures the movable part of the reset assembly 5, and the pull rope 7 is used to increase the strength of the RV roof; such as Figure 2 and Figure 4As shown, specifically, the electromagnetic locking assembly 6 includes a lock hole 601 opened on the surface of the third frame 501, an electromagnet 602 is fixedly installed on the inner wall of the lock hole 601, an armature 603 is slidably installed in the lock hole 601, a locking pin 604 is fixedly installed on the end face of the armature 603, the locking pin 604 is movably inserted into the movable block 503, and a second spring 605 is provided between the armature 603 and the electromagnet 602.

[0031] More specifically, when the top frame 2 and the flexible enclosure 4 are fully extended, their locking pins 604 correspond to the locking holes 601 on the surface of the third frame 501. Under the elastic force of the second spring 605, the locking pins 604 are inserted into the locking holes 601 to fix the movable block 503. When the top frame 2 and the flexible enclosure 4 are retracted, the electromagnet 602 is energized to generate a magnetic field, which attracts the armature 603 and compresses the second spring 605, causing the locking pins 604 to be pulled out from the locking holes 601 on the surface of the third frame 501, thus releasing the restriction on the movable block 503.

[0032] In some practical applications, when the top frame 2 and the flexible enclosure 4 are fully extended, the locking pin 604 that is movably inserted into the movable block 503 is correspondingly set with the lock hole 601 on the surface of the third frame 501. The locking pin 604 is machined and inserted into the lock hole 601 to limit the movable block 503.

[0033] More specifically, the movable block 503 is locked and limited by inserting the locking pin 604 into the locking hole 601 on the surface of the third frame 501.

[0034] In summary: the shear-type lifting assembly 3 enables the base 1 and the top frame 2 to unfold. Simultaneously, as the top frame 2 moves vertically upward, the pull rope 7 pulls the movable part of its reset assembly 5 closer together. When the top frame 2 and the flexible enclosure 4 are fully unfolded, the electromagnetic locking assembly 6 fixes the movable part of the reset assembly 5, ensuring that the top frame 2 remains in the unfolded state. At the same time, the presence of the pull rope 7 enhances the overall strength of the RV roof, reduces excessive deformation or shaking of the roof 21 due to external forces during use, and increases its structural strength.
