Description

Technical Field

[0001] The invention belongs to the technical field of tents, and in particular relates to an automatically deployable tent. Background Art

[0002] There are generally two types of existing large-scale storage tents. One is the traditional truss tent, which uses a keel frame as a support frame, and then fixes the tarpaulin to the keel to achieve deployment. The keel frame can be assembled or folded in various ways. The other is the inflatable tent, which uses inflatable air columns (commonly known as air ribs) as support. The air columns are generally combined with the tent tarpaulin and are inflated by an air pump to expand the air columns. The tent is then pulled in a certain direction to deploy. The air columns are divided into high-pressure air column tents and low-pressure air column tents based on their pressure bearing capacity. These large storage tents require an area of ​​hundreds of square meters. Using these two conventional technical methods, the deployment and retrieval time and manpower required are not fast and efficient. Although inflatable tents are faster than truss tents, the weight of hundreds of square meters can reach several tons. Since the tent is mainly composed of soft materials, it is difficult to deploy or retrieval using conventional machinery. In addition, uneven force on the tent body often causes the tent to tear and damage.

[0003] As mentioned above, the existing technical means for deploying and retracting large-scale storage tents have the problems of long operation time, low operation efficiency, consumption of personnel physical strength, easy damage to the tent body, low degree of integration, and large size after folding.

[0035] Example 1:

[0036] like Figure 1 and Figure 2 The present invention provides an automatic tent, comprising: an integrated container 1, a tent body assembly 2, and an electric roller retracting mechanism 3. The integrated container 1 adopts a 1C type standard container, and four sets of the electric roller retracting mechanisms 3 are fixedly installed inside the integrated container to facilitate integrated transportation. Figure 3 The electric roller retracting mechanism 3 is shown to correspond to the tent body assembly 2 one by one, that is, each electric roller retracting mechanism 3 corresponds to one set of tent body assembly 2. The electric roller retracting mechanism 3 is used to unfold and retract the tent body assembly 2. Figure 4 The tent assembly 2 is an inflatable tent structure. When collapsed, it is wound and stored within the electric roller retracting mechanism 3. When deployed, it detaches from the electric roller retracting mechanism 3. Each set of tent assembly 2 and electric roller retracting mechanism 3 can be deployed and retracted independently. The automatically deployable tent is powered by a 3KW diesel generator 314 during deployment and folding. After the tent is set up, the electrical devices of the tent assembly 2 during daily use are connected to the mains power supply system.

[0037] Example 2:

[0038] The tent assembly 2 is an inflatable tent structure, comprising air columns 201, an outer tarpaulin 202, an inner tarpaulin, ventilation ducts, and fixing components. The air columns 201 are an integrated, crisscrossed structure, with hangers, pulleys, and traction ropes installed on their interior. When deployed, they are inflated with air to support the tent, and when retracted, the air is expelled for easy storage. Snap-on connector components 205 are installed on either side of the air columns 201 to connect and secure the tent assembly 2. The outer tarpaulin 202 is bonded to the exterior of the air columns 201, providing rain and wind protection for the entire tent. Snap-on connector components 205 are installed on either side of the outer tarpaulin 202 to connect the outer tarpaulin 202 when the tent assembly 2 is spliced. Zippers and Velcro are also installed on both sides of the outer tarpaulin 202 to reinforce and waterproof the two tent assembly 2s. The inner tarpaulin is placed inside the inflated air column 201 via the hangers, pulleys, and traction ropes inside the air column 201, providing insulation and decorative features. When the tent assembly 2 is retracted, the inner tarpaulin is removed from the hangers and stored separately. The ventilation duct is installed inside the outer tarpaulin 202 and is integrated with the outer tarpaulin 202. It is connected to the cooling and heating outlets of the air conditioning system to provide cooling and heating air to the entire tent. The fixing assembly includes ground pegs and wind ropes, which are used to secure the entire tent after it is erected.

[0039] When assembling the whole tent, each group of air columns 201 is unfolded and placed in the corresponding position, and the air columns 201 are inflated by a blower until the standard air pressure is reached. At this time, the air columns 201 are formed as shown in FIG. Figure 4 The status shown. Figure 5 After the multiple groups of air columns 201 are inflated, they can be spliced ​​together. Figure 6 The snap-on connection components 205 at corresponding positions on one side of two adjacent groups of gas columns 201 are overlapped and buckled together; Figure 7 Pull up the zippers (i.e., zippers) at the corresponding positions on one side of the outer tarpaulin 202 of the adjacent two groups of air columns 201 and stick the hook and loop fasteners (commonly known as Velcro) in an overlapping manner. This connection method can effectively play a waterproof and windproof role. Finally, Figure 8 The snap-on connection components 205 at corresponding positions of the two sets of outer tarpaulins 202 are overlapped and buckled to increase the splicing strength. In this way, the splicing operation of the two sets of tent body components 2 is completed, and the splicing of other tent body components 2 is carried out in this way, and the number of spliced ​​tent body components 2 is determined according to the needs.

[0040] The materials and material parameters of the air column 201, outer tarpaulin 202, and inner tarpaulin in the tent assembly 2 are as follows:

[0041] The air column 201 is made of PVC composite material, with tensile strength: warp ≥3500N / 5cm, weft ≥3200N / 5cm, tear strength: warp ≥450N, weft ≥300N, flame retardant performance: B1 grade, puncture resistance: ≥180N;

[0042] The outer tarpaulin 202 is made of camouflage coated flame retardant Oxford cloth material, mass: ≤470g / ㎡, density: 105±5 pieces / 10cm in warp direction, 100±5 pieces / 10cm in weft direction, breaking strength: radial T≥4300N, weft W≥3700N, tearing strength: radial T≥200N, weft W≥150N, hydrostatic pressure: >40kPa, water exposure: ≥3 levels, flame retardancy: afterburning time ≤5s, shade Burning time ≤ 5s, damaged length ≤ 150mm, color fastness: ≥ Level 4, thermal infrared emissivity: ≤ 0.55, surface resistivity: 106~109Ω, flat grinding: ≥ 4500 times, operating temperature: -40℃~+60℃, aging performance (300h): breaking strength, warp ≥ 1500N, weft ≥ 1000N, color difference ≤ 4L*a*b*60°, mirror gloss no more than 5, with camouflage performance;

[0043] The inner tarpaulin is made of white flame-retardant Oxford cloth with a unit area mass of ≤200g / ㎡, breaking strength: ≥1000N in warp direction, ≥800N in weft direction, tearing strength: ≥50N in warp direction, ≥40N in weft direction, adhesion strength: cannot be peeled off, infrared emissivity of aluminum powder coating: ≤0.55, vertical burning: afterburning time ≤5s, smoldering time ≤5s, damaged length ≤150mm, water exposure: ≥level 3, hydrostatic pressure: ≥5Kpa, surface resistivity: ≤109Ω.

[0044] Example 3:

[0045] like Figure 9 As shown, inflation and deflation valves 203 are provided at diagonal positions on either side of the air column 201. The inflation and deflation valves 203 comprise a valve body, an inflation valve, and a deflation valve. The valve body is installed at diagonal positions on either side of the air column 201, and the inflation and deflation valves are installed inside. The inflation and deflation valves are one-way valve structures used to charge and discharge the gas within the air column 201. When inflating the air column 201, the inflation valve of the inflation and deflation valves 203 is opened and the deflation valve is closed, allowing gas to enter the air column 201. When deflated, the inflation valve of the inflation and deflation valves 203 is closed and the deflation valve is opened, allowing gas to exit the air column 201.

[0046] Safety valves 204 are also provided diagonally on both sides of the gas column 201; the safety valves 204 include a valve body, an exhaust valve, and an elastic element. The valve body is installed at the diagonal positions on both sides of the gas column 201, and the exhaust valve and the elastic element (the elastic element can be a spring) are installed inside to prevent the risk of the gas column 201 exploding due to the internal air pressure of the gas column 201 exceeding the rated value. Under normal conditions, the exhaust valve of the safety valve 204 is in a closed state under the pressure of the elastic element. When the pressure inside the gas column 201 is too high and exceeds the pressure of the elastic element, the gas inside the gas column 201 pushes open the exhaust valve and is discharged outward. At this time, the pressure inside the gas column 201 is reduced, thereby preventing the gas column 201 from exploding due to excessive pressure. When the pressure inside the gas column 201 is lower than the pressure of the elastic element, the exhaust valve is closed again under the pressure of the elastic element, and the gas column 201 stops exhausting.

[0047] Example 4:

[0048] like Figure 10The electric roller retracting and unfolding mechanism 3 shown in the figure includes a retracting and unfolding control switch 301, a main reel 302, a traction tarpaulin 309, a transmission reel 305, a gear device 313, a motor 314, a hand-cranking mechanism 306, and a traction extrusion shaft 310. The retracting and unfolding control switch 301 is connected to the motor 314 via a cable or wirelessly, and a start and stop button are installed thereon for controlling the start and stop states of the motor 314 respectively. The motor 314 is installed at one end of the transmission reel 305 and is connected to the transmission reel 305 via the gear device 313 to transmit power. The gear device 313 is installed between the motor 314 and the transmission reel 305 and includes a gear transmission mechanism and an operating mechanism. By manually operating the operating mechanism, the meshing mode of the gear transmission mechanism can be changed to realize the connection and disconnection of power and the switching between forward and reverse transmission of power. The main reel 302 has an axial groove 303 on its outer surface, with a hanging hole 304 within the groove. A hook is provided on one side of the traction tarpaulin 309, which is connected to the hanging hole 304 when the tent assembly 2 is retracted. The transmission reel 305 is coaxially fixedly connected to the main reel 302 and extends through the main reel 302. The transmission reel 305 can drive the main reel 302 to rotate, and the motor 314 and the hand-crank mechanism 306 can respectively provide power to the transmission reel 305. The hand-crank mechanism 306 is mounted on the other end of the transmission reel 305 and is fixedly connected to the transmission reel 305. When there is no power supply or when power supply is not required, the gear device 313 can be switched to a power-off state to disconnect the power transmission between the motor 314 and the gear device 313, thereby disconnecting the power transmission between the motor 314 and the gear device 313, and the tent assembly 2 can be manually deployed and retracted by the hand-crank mechanism 306. The traction and extrusion shaft 310 is installed obliquely below the main reel 302, and includes a support shaft 308 and a pressure shaft 310. The two ends of the support shaft 308 are supported by bearings and installed on the bracket. An elastic element is installed between the bracket and the bearing to realize the up and down movement of the support shaft 308, and the moving distance is not more than 50mm. The pressure shaft 310 is installed above the fixed shaft, and there is a gap of 100mm to 150mm between it and the fixed shaft. One end of the pressure shaft 310 is supported on the bracket by a movable bearing 307, and the other end is connected to the main reel 302 through a gear mechanism 312, and is locked to the bracket by a buckle 311. The pressure shaft 310 can be driven to rotate by the main reel 302 through the gear mechanism 312. The buckle 311 can be opened or locked, so that the pressure shaft 310 can swing around the bearing end. When the tent assembly 2 is folded, the main reel 302 and the traction and extrusion shaft 310 work together to remove the remaining gas in the air column 201 of the tent assembly 2, and the traction and extrusion shaft 310 automatically removes debris stuck when the tent is folded.

[0049] The electric roller retracting mechanism 3 can realize the electric and manual rapid deployment and retraction of the tent assembly 2. The specific implementation is as follows:

[0050] To unfold the tent assembly 2, the gear mechanism 313 is switched to reverse transmission, and the motor 314 is activated via the retraction / expansion control switch 301. The rotation of the motor 314 drives the transmission reel 305 through the gear mechanism 313, which in turn drives the main reel 302. While the main reel 302 rotates, a person is required to pull the end of the tent assembly 2 outward to fully unfold the tent assembly 2 wrapped around the main reel 302.

[0051] To retract the tent assembly 2, deflate it and lay it flat in the corresponding position of the integrated container 1. Open the catch 311 on the geared end of the pressure shaft 310 of the traction and extrusion shaft 310. Rotate the pressure shaft 310 around the movable bearing 307 to create a sufficient distance between it and the support shaft 308. Connect the hook on one side of the traction tarpaulin 309 to the hook hole 304 in the axial groove 303 of the main reel 302. Switch the gear mechanism 313 to forward drive. Activate the motor 314 via the retraction and extension control switch 301. The gear mechanism 313 drives the transmission reel 305, which in turn drives the main reel 302, causing the traction tarpaulin 309 to be wound around the main reel 302. The tent assembly 2 is then overlapped with the traction tarpaulin 309. The friction generated by the overlap between the traction tarpaulin 309 and the tent assembly 2 drives the tent assembly 2 to move together. Close one end of the traction and extrusion shaft 310 and lock the buckle 311. At this time, the main reel 302 drives the tent body component 2 to be wound around the main reel 302. When the tent body component 2 passes through the gap of the traction and extrusion shaft 310, the residual gas inside the tent body component 2 is squeezed out of the tent body component 2, thereby achieving the purpose of reducing the storage space.

[0052] In addition, the electric roller retracting mechanism 3 can also realize the manual deployment and retraction of the tent assembly 2 in the absence of power supply, specifically in the following manner:

[0053] To manually unfold the tent assembly 2, the gear mechanism 313 is switched to reverse drive, and the gear meshing between the motor 314 and the transmission reel 305 is disengaged. The hand crank mechanism 306 is then turned to rotate the transmission reel 305, which in turn rotates the main reel 302. While the main reel 302 rotates, a person is required to pull the end of the tent assembly 2 outward to fully unfold the tent assembly 2 wrapped around the main reel 302.

[0054] When the tent assembly 2 is manually withdrawn, the process is basically the same as the electric withdrawal process, except that the driving power is provided by human power, which drives the transmission reel 305 through the hand-crank mechanism 306 instead of the motor 314.

[0055] Example 5:

[0056] The electric roller retracting and unfolding mechanism 3 also includes a control module, which includes a speed sensor, a current sensor, a position sensor, a processor, and a power controller. The speed sensor is installed on the output shaft of the motor 314 and can collect the speed value of the output shaft of the motor 314 in real time and transmit the speed value to the processor. The current sensor is connected to the input circuit of the control module and can collect the current value in the circuit in real time and transmit the current value to the processor. The position sensor is installed on the end of the main reel 302 near the motor 314 and can collect the position value of the tent assembly 2 during expansion and contraction in real time. The position value is 1 when the tent assembly 2 is being expanded or contracted, and the position value is 0 when it is fully expanded or fully contracted. The position sensor transmits the position value to the processor. The processor is the data processing and control component of the control module. It is integrated with the power controller and connected between the motor 314 and the power supply. The processor receives the speed and current values ​​transmitted by the speed sensor and current sensor. The processor is preset with the rated output torque of the motor 314. The processor processes the received speed and current values ​​to calculate the actual output torque of the output shaft of the motor 314, compares it with the rated torque, and uses the comparison result to control the output current of the power controller circuit, thereby controlling the output torque of the motor 314, thereby preventing damage to the tent assembly 2 due to excessive torque. The processor receives the position value transmitted by the position sensor. When the position value is 1, the processor sends a command to the power controller to keep the circuit connected. When the position value is 0, the processor sends a command to the power controller to disconnect the circuit, thereby controlling the start and stop of the motor 314, thereby automatically shutting down the motor 314 when the tent assembly 2 is deployed and retracted.
