Description

Technical Field

[0001] This invention relates to the field of outdoor tent technology, specifically to a fully automatic rapid deployment and retraction linkage mechanism for outdoor tents. Background Technology

[0002] Outdoor tents are essential equipment for camping, outdoor excursions, disaster relief, and other scenarios, and the ease of deployment and folding up directly affects the user experience. Traditional outdoor tents mostly use a manual pole structure, which requires manually opening each pole, straightening the tent fabric, and fixing the ground pegs when deploying. Folding up requires the reverse operation, which is cumbersome and time-consuming. Especially in inclement weather or emergencies, manual operation is inefficient and labor-intensive.

[0003] In response to the above problems, the automated articulated tent frame driven by a screw and sliding sleeve was developed. The motor drives the screw to move the sliding sleeve up and down along the central main shaft. The sliding sleeve pushes multiple sets of diagonal connecting rods to open or close the main support rod.

[0004] On the one hand, existing screw-driven linkage tents have exposed screws that lack protective structures, making them susceptible to corrosion and jamming from rain and sand when used outdoors.

[0005] On the other hand, during the opening and closing of the tent, without the aid of the tent fabric to straighten the structure, it is necessary to hold the main pole with one hand and straighten the folds of the tent fabric with the other hand. The operation is cumbersome and lacks automation. Therefore, it is necessary to propose a fully automatic and rapid opening and closing linkage mechanism for outdoor tents. Summary of the Invention

[0006] To address the problems in the prior art, this invention provides a fully automatic and rapid deployment and retraction linkage mechanism for outdoor tents.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a fully automatic rapid deployment and retraction linkage mechanism for an outdoor tent, including a top plate, a main pole tube connected to the bottom end of the top plate, a sliding sleeve slidably sleeved on the outside of the main pole tube, a number of support rods hinged on the top plate, an oblique hinge rod hinged between the support rods and the sliding sleeve, and a number of sliding grooves opened on the outer wall of the main pole tube; A servo motor is embedded in the top wall of the main rod cylinder. The output end of the servo motor is connected to a lead screw, and the bottom of the lead screw is rotatably mounted on the bottom wall of the main rod cylinder. A slider is threaded onto the outside of the lead screw. Several limiting blocks are connected to the outer wall of the slider. A vertical rod is connected between the top and bottom of the sliding groove. The upper and lower ends of the vertical rod are provided with rod wall grooves. Several sets of vibration components are embedded in the rod wall grooves. The vibration components include a collar sleeved in the rod wall groove. Two abutment rings are connected to the outer wall of the collar. An outer ring is sleeved on the outside of the abutment ring. A contact ring is connected to the middle of the inner wall of the outer ring. A flat spiral coil is connected between the collar and the contact ring.

[0008] Specifically, the top of the top plate has a spherical protrusion.

[0009] Specifically, elastic sealing sleeves are distributed between the lower outer end of the top plate and the main rod cylinder and the sliding sleeve, and the elastic sealing sleeves are generally wavy.

[0010] Specifically, the limiting block is slidably engaged in the groove, and the limiting block is slidably sleeved on the outside of the vertical rod.

[0011] Specifically, the compressive forces on both sides of the flat helical coil and the contact ring are different.

[0012] Specifically, there is a gap between the outer ring and the retaining ring.

[0013] The first beneficial effect of this invention is that the mechanism is equipped with a wave-shaped EPDM elastic sealing sleeve, which can extend and retract with the sliding sleeve, continuously sealing and isolating the lead screw assembly, preventing outdoor rainwater and sand from entering, effectively avoiding lead screw corrosion and jamming, and greatly improving the reliability of the mechanism in the field. A servo motor, in conjunction with the lead screw and sliding sleeve, drives multiple sets of hinged connecting rods, synchronously driving the support poles to complete the automatic unfolding and retraction of the tent fabric; relying on a single power source to achieve the frame movement eliminates the need for manual tent fabric arrangement, reducing operational difficulty and improving the efficiency of automated tent setup.

[0014] The second beneficial effect of this invention is that the addition of a shaking component creates a difference in compression force on both sides of the flat spiral coil. When the limiting block impacts the outer ring, it generates a cam-like offset motion of translational compression, producing a small vibration. The vibration is triggered only in the initial stroke range of unfolding and folding. During the unfolding stage, it shakes out the folds of the tarpaulin; during the folding stage, it breaks up the knots and clumps of the tarpaulin, preventing it from getting stuck in the hinge gaps.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] Example 1: refer to Figures 1-4 The structure shown is a fully automatic rapid deployment and retraction linkage mechanism for an outdoor tent, including a top plate 1, a main pole tube 11 connected to the bottom end of the top plate 1, a sliding sleeve 12 slidably sleeved on the outside of the main pole tube 11, several support rods 13 hinged on the top plate 1, an oblique hinge rod 14 hinged between the support rods 13 and the sliding sleeve 12, several sliding grooves 101 opened on the outer wall of the main pole tube 11, a servo motor 2 embedded in the inner top wall of the main pole tube 11, a lead screw 21 connected to the output end of the servo motor 2, and the bottom of the lead screw 21 rotatably set on the inner bottom wall of the main pole tube 11, a slider 22 threaded on the outside of the lead screw 21, and several limit blocks 210 connected to the outer wall of the slider 22; The top of the top plate 1 is spherical and protruding. Elastic sealing sleeves 15 are distributed between the lower outer end of the top plate 1 and the main rod cylinder 11 and the sliding sleeve 12. The elastic sealing sleeve 15 is wavy in shape. The limiting block 210 is slidably engaged in the sliding groove 101.

[0020] Among them, the elastic sealing sleeve 15 is made of EPDM ethylene propylene rubber, which is weather-resistant and anti-aging, and can resist outdoor rain and sand and dust erosion. The elastic sealing sleeve 15 wraps around the outside of the main rod cylinder 11 and the sliding sleeve 12, isolating the transmission area of ​​the lead screw 21 from the external environment, and preventing the lead screw 21 from rusting and jamming due to the outdoor environment.

[0021] Servo motor 2 is electrically connected to an external controller, which controls the forward and reverse rotation, start and stop, and running stroke of servo motor 2.

[0022] The support pole 13 is a long support pole for the outside of the tent. The tent fabric is fixedly tied to the outside of the support pole 13. The diagonal hinge rod 14 is a linkage support rod and is not directly connected to the tent fabric. When the sliding sleeve 12 moves upward, the diagonal hinge rod 14 pushes the support pole 13 outward, and all the support poles 13 open outward at the same time, opening the tent fabric outward to realize the tent unfolding. When the sliding sleeve 12 moves downward, the diagonal hinge rod 14 pulls the support pole 13 to fold inward, and the support pole 13 drives the tent fabric to stack and fold inward, completing the tent fabric storage.

[0023] In use, the external controller outputs a signal to drive the servo motor 2 to rotate forward or reverse, which in turn drives the lead screw 21 to rotate. This causes the slider 22, along with the limit block 210, to move up and down along the slide groove 101. The slider 22 moves up and down synchronously with the sliding sleeve 12. The sliding sleeve 12 moves up and down, pulling the oblique hinge rod 14, which in turn drives the support rod 13 to complete the unfolding or folding of the tent frame. The wave-shaped elastic sealing sleeve 15 moves and extends with the sliding sleeve 12, continuously protecting the area of ​​the lead screw 21.

[0024] Example 2: Based on the above embodiment one: (refer to...) Figures 4-6 The structure shown; Unlike Embodiment 1, a vertical rod 3 is connected between the top and bottom of the slide groove 101. The upper and lower ends of the vertical rod 3 are provided with rod wall grooves 301. Several sets of shaking components are embedded in the rod wall grooves 301. The shaking components include a collar 31 sleeved in the rod wall groove 301. Two abutment rings 32 are connected to the outer wall of the collar 31. An outer ring 33 is sleeved on the outside of the abutment ring 32. A contact ring 34 is connected to the middle of the inner ring wall of the outer ring 33. A flat spiral coil 35 is connected between the collar 31 and the contact ring 34. Furthermore, the limiting block 210 is slidably sleeved on the outside of the vertical rod 3, the compression forces on both sides of the flat spiral coil 35 and the contact ring 34 are different, and there is an active gap 302 between the outer ring 33 and the collar 31.

[0025] Among them, the flat spiral coil 35 is made of 65Mn spring steel, which has good elastic deformation and rebound performance; the compression force is different: the uneven force on both sides causes the outer ring 33 to produce translational compression, forming a cam-like offset movement, which in turn produces a small mechanical vibration, and the movable gap 302 provides impact buffer space for the outer ring 33.

[0026] In use, the external controller issues a command, the servo motor 2 drives the lead screw 21 to rotate, and the slider 22 drives the limit block 210 to rise and fall along the vertical rod 3. When the limit block 210 moves to the position of the shaking component at the top or bottom of the vertical rod 3, the limit block 210 hits the outer ring 33. Because the compression force of the flat spiral coil 35 on both sides of the contact ring 34 is not equal, the outer ring 33 undergoes translational compression, producing a cam-type offset motion, and relies on the elastic element to rebound to form a small vibration. The vibration is transmitted to the entire connecting rod frame, which shakes out the folds of the tarpaulin in the initial stage of unfolding and prevents the tarpaulin from twisting and clumping in the initial stage of packing, and avoids the tarpaulin from getting stuck in the hinge gap. When the limit block 210 leaves the shaking component area, the impact stops and the vibration disappears.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention.
