Description

Technical Field

[0001] This utility model relates to a device that uses an air pump as a power source for linear reciprocating motion, belonging to the field of entertainment equipment technology. Background Technology

[0002] In simulation amusement rides, such as simulated cannons and battlefield experience devices, linear reciprocating motion is a core function for creating a realistic scene. Existing technologies have the following significant drawbacks: High transmission rigidity, no cushioning experience: The mainstream uses crank-slider and gear-rack transmission, which rely on mechanical hard connection to transmit power. During the movement, rigid vibration is easy to be generated, and there is no cushioning structure. Players are prone to discomfort and poor human-computer interaction experience. Slow power response and poor adaptability: Most of them are driven by motors, which require power to be transmitted through a reduction mechanism, resulting in a delayed response and making it impossible to simulate real-world scenarios of rapid round trips; moreover, the motor speed is fixed, making it difficult to adjust the round trip speed according to the needs of the scenario. Low guiding accuracy and severe wear: Some equipment only guides at one end, which easily leads to deviation during the round trip, resulting in accelerated wear of components and high noise. High maintenance costs: The crank-slider and gear-rack transmissions have many wear parts that need to be replaced on average every 3 months, and maintenance costs account for 20% of the total equipment cost. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a device for linear reciprocating motion powered by an air pump. Through the coordinated design of air pump drive, joint bearing buffer, dual guidance and elastic reset, it achieves low vibration, high precision and fast response linear reciprocating motion, thereby enhancing the realism and experience of amusement equipment.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A device for linear reciprocating motion powered by an air pump includes a device base and a gun barrel. The device base is provided with a cylinder for driving the gun barrel. A connector is provided between the output end of the cylinder and the tail end of the gun barrel. A return spring is provided between the tail end of the gun barrel and the device base for resetting the gun barrel.

[0005] Preferably, the end of the equipment base is provided with a guide sleeve for guiding the gun barrel.

[0006] Preferably, the connector includes a spherical bearing, which is fixed to the output end of the cylinder. The spherical bearing is connected to a barrel connecting plate via a connecting pin, and the barrel connecting plate is connected to the barrel.

[0007] Preferably, the bottom of the barrel connecting and fixing plate is provided with a guide rail slider, and the equipment base is provided with a guide rail corresponding to the guide rail slider.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: The pneumatic transmission of the cylinder and the angle compensation of the joint bearing work together to eliminate the rigid vibration of the mechanical hard connection. The elastic reset of the return spring further buffers the return impact, improving the player's physical comfort and solving the problem of strong vibration and discomfort in the existing equipment. The linear guidance of the guide rail and guide rail slider, combined with the radial constraint of the guide sleeve 7, reduces the reciprocating offset of the gun barrel. The lubrication groove design reduces wear, extends the service life of components, and reduces maintenance costs. With the elimination of complex transmission components such as cranks, sliders, gears, and racks, the number of parts is reduced. The silent design of the joint bearings and guide rails reduces operating noise and creates a more immersive amusement scene atmosphere. Attached Figure Description

[0012] 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.

[0013] Please see Figures 1-2 This utility model provides a technical solution: like Figure 1 and Figure 2As shown, a linear reciprocating motion device powered by an air pump includes a base 10 and a cannon 6. The base 10 is welded from Q235 steel plate, measuring 500mm in length, 200mm in width, and 80mm in height. It is coated with 80μm thick anti-rust paint and has four 12mm diameter mounting holes at the bottom for fixing it to the amusement equipment frame. A cylinder 1 for driving the cannon 6 is mounted on the base 10. The cylinder 1 is a standard SC series cylinder, model SC40X150, with a 40mm diameter and a 150mm stroke. The air source is provided by an air pump, with a working pressure of 0.4-0.6MPa. A connector is provided between the output end of the cylinder 1 and the tail end of the cannon 6. A return spring 5 is provided between the tail end of the cannon 6 and the base 10 to reset the cannon 6. The cylinder 1 and the base 10 are arranged horizontally at a 0° angle to ensure the power direction is parallel to the guide rail 3.

[0014] Specifically, the return spring 5 is made of 304 stainless steel spring wire with a free length of 300mm and a stiffness coefficient of 10N / mm. One end is fixed to the middle of the equipment base 10 through a spring seat, and the other end is hooked on the spring hanging hole of the barrel connection fixing plate 9. In its natural state, the return spring 5 is in a slightly stretched state with a pre-extension of 5mm to ensure that the barrel 6 can be quickly pulled back to its original position when the cylinder 1 exhausts air, with a reset time of ≤0.3 seconds.

[0015] Furthermore, the end of the equipment base 10 is provided with a guide sleeve 7 for guiding the gun barrel 6. The guide sleeve 7 is made of wear-resistant cast iron HT200, and its inner diameter is clearance-fitted with the outer diameter of the gun barrel 6. It is fixed to the front end of the equipment base 10 by a bracket. The inner wall of the guide sleeve 7 has a lubrication groove with a width of 2mm and a depth of 1mm, which is filled with lithium-based grease to reduce the wear of the gun barrel 6 during reciprocating motion and prevent the gun barrel 6 from radially shifting.

[0016] Furthermore, the connecting component includes a spherical bearing 2. The piston rod end of the cylinder 1 is fixed to the spherical bearing 2 by an internal thread. The extension and retraction speed of the piston rod can be adjusted by a valve to adapt to the reciprocating speed requirements of different scenarios. The spherical bearing 2 is connected to the barrel connecting plate 9 by a connecting pin 4. The barrel connecting plate 9 is connected to the barrel 6. The spherical bearing 2 adopts the GE20ES series radial spherical bearing. The outer ring is fixed to the piston rod of the cylinder 1, and the inner ring is hinged to the barrel connecting plate 9 by the connecting pin 4. The spherical bearing 2 can compensate for the installation error of ±2°, reduce the additional torque in the transmission process, avoid rigid impact, and reduce noise. The operating noise is ≤50dB.

[0017] Furthermore, a guide rail slider 8 is provided at the bottom of the barrel connecting and fixing plate 9, and a guide rail 3 corresponding to the guide rail slider 8 is provided on the equipment base 10. The cylinder 1 and the guide rail 3 are fixed on the upper surface of the equipment base 10 by bolts to ensure that the parallelism between the two is ≤0.1mm. The barrel connecting and fixing plate 9 is made of 5052 aluminum alloy plate with a thickness of 10mm. One side is rigidly connected to the tail end of the barrel 6 by bolts with a preload torque of 8-10N・m. The other side has a pin hole with a diameter of 10mm. The clearance between the connecting pin 4 and the inner ring of the spherical bearing 2 is ≤0.05mm. The guide rail slider 8 is fixed on the lower surface of the fixing plate 9 by bolts and slides with the guide rail 3.

[0018] Specifically, the guide rail 3 adopts an HGR15 linear guide rail with a track width of 15mm. It is fixed to the equipment base 10 by T-bolts. The parallelism error of the guide rail 3 is ≤0.05mm / m. The guide rail slider 8 is an HGW15CA model adapted to the guide rail 3 with a rated dynamic load of 12.5kN. It is rigidly connected to the barrel connection fixing plate 9 to ensure the straightness of the reciprocating motion is ≤0.1mm / 100mm.

[0019] The workflow of this embodiment is as follows: The air pump supplies air to the rodless chamber of cylinder 1, the piston rod extends, and drives the barrel connecting and fixing plate 9 to move forward along the guide rail 3 through the spherical bearing 2 and connecting pin 4. The guide rail slider 8 cooperates with the guide rail 3 to ensure accurate guidance. The barrel 6 moves forward synchronously under the constraint of the guide sleeve 7. The return spring 5 is stretched to a maximum elongation of 120mm and the elastic force is 1200N. During reset, the rodless chamber of cylinder 1 exhausts air and the rod chamber supplies air, the piston rod retracts, the reset spring 5 releases its elastic potential energy, and pulls the barrel connecting fixing plate 9 to move backward along the guide rail 3 until it returns to the initial position, completing one round-trip motion. The round-trip cycle can be adjusted by the air valve by 0.5-1 seconds / cycle.
