[0002] When displaying a mechanical model, the model is usually fixed on a display stand, and then the display stand is driven to rotate for automatic display. In order to prevent the model from being damaged or to prevent the dynamic model from accidentally injuring others, a protective cover is usually set on the display stand to isolate the model from the outside. This makes it impossible to observe some tiny details of the model at close range. The details can be partially photographed and magnified by video and displayed on a monitor. However, in existing devices, the camera equipment is generally fixed and the display stand is automatically rotated to capture and magnify the details. However, it is impossible to capture the model from all angles, and some details cannot be displayed. Summary of the Invention

[0046] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0047] like Figure 1-10 As shown, an automated model display device for mechanical design and manufacturing includes:

[0048] Circular track 6;

[0049] A moving seat 9 is slidably arranged in the annular track 6, and a curved slide rail 3 is fixedly arranged on the top of the moving seat 9;

[0050] The reciprocating moving unit provided in the arc-shaped slide rail 3 includes:

[0051] Telescopic airbag 7;

[0052] A slider 4 is fixedly arranged on the sliding end of the telescopic airbag 7;

[0053] A camera 5 is fixedly mounted on the bottom of the slider 4;

[0054] The pneumatic unit provided in the movable seat 9 comprises:

[0055] A guide housing 13 is arranged in a vortex shape and communicated with the external air, wherein the air inlet is provided at the center of the guide housing 13 and the air outlet is communicated with the telescopic airbag 7;

[0056] Centrifugal blades 14 are evenly distributed and rotatably arranged in the guide shell 13 in the circumferential direction;

[0057] A gear 15 drivingly connected to the centrifugal blade 14;

[0058] The reset unit provided in the movable seat 9 comprises:

[0059] Reel 10;

[0060] A traction rope 8 connecting the wire wheel 10 and the slider 4;

[0061] An elastic energy storage element connected to the fixed axis of the reel 10;

[0062] The inner wall of the annular track 6 is provided with an intermittent rack 20, and the gear 15 is movably arranged in the rack 20. The rack 20 includes a tooth segment and a smooth segment.

[0063] When the gear 15 moves in the tooth segment, the centrifugal blades 14 pressurize the external airflow and fill it into the telescopic airbag 7. The telescopic airbag 7 expands and deforms, pushing the slider 4 to move toward the top along the arc-shaped slide rail 3. The traction rope 8 pulls the reel 10 to rotate and causes the elastic energy storage element to store energy.

[0064] When the gear 15 moves in the smooth section, the elastic energy storage element releases energy, driving the pulley 10 to reverse and rewind the traction rope 8 and pull the slider 4 to reset in the opposite direction, thereby driving the camera 5 to rotate around the model and periodically reciprocate on the arc-shaped slide rail 3 to achieve panoramic shooting of the model without blind spots.

[0065] Specifically, when displaying a mechanical model, the model is usually fixed on a display stand, and then the display stand is driven to rotate to automatically display the model. In order to prevent the model from being damaged or to prevent the dynamic model from accidentally injuring others, a protective cover is usually set on the display stand to isolate the model from the outside. This makes it impossible to observe some tiny details of the model at close range. The details can be partially photographed and magnified by video and displayed on a monitor. However, in existing devices, the camera equipment is generally fixed and the camera and partial magnification are performed by the automatic rotation of the display stand. However, it is impossible to capture the model without blind spots, and some details still cannot be displayed.

[0066] Furthermore, when displaying the model, the device first fixes the model on the circular exhibition stand 1 on the top of the base, and then covers the outside of the model with a transparent protective cover 2, and fixes it to the circular exhibition stand 1 with bolts. The annular track 6 is arranged on the outer ring of the circular exhibition stand 1 and is coaxial with the circular exhibition stand 1. By driving the motor fixed on the movable seat 9, the first gear fixed on the output end of the motor is driven to rotate in the annular tooth groove opened in the base, so that the first gear engages with the teeth on the inner ring wall of the annular tooth groove, thereby driving the movable seat 9 to move along the annular track 6 under the limitation of the annular track 6, thereby driving the arc slide rail 3 fixed on the top of the movable seat 9 to make circumferential motion around the circular exhibition stand 1.

[0067] Furthermore, the movable seat 9 moves in the annular track 6, thereby driving the gear 15 to move in the rack 20 provided on the inner wall of the annular track 6. Since the rack 20 is intermittently provided, during the movement of the gear 15, the reciprocating moving unit has the following stroke:

[0068] When the gear 15 moves in the tooth segment of the rack 20, the gear 15 is engaged with the tooth segment, so the gear 15 is driven to rotate. The rotation of the gear 15 drives the rotating shaft 12 fixed on the gear 15 and passing through the guide shell 13 to rotate, thereby driving the centrifugal blades 14 fixed at the other end of the rotating shaft 12 to rotate. The centrifugal blades 14 rotate, so that the gas between the centrifugal blades 14 is radially thrown to the inner wall of the guide shell 13 by the centrifugal force, so that the gas density in the center area of the centrifugal blades 14 drops sharply to form a negative pressure area. Under the action of the pressure difference, the outside air is sucked into the central low-pressure area from the axial air inlet of the guide shell 13. Since the guide shell 13 is vortex-shaped The arrangement decelerates the high-speed airflow, converts kinetic energy into static pressure energy, and forms a high-pressure area at the outlet, thereby directing the gas into the telescopic airbag 7 from the air outlet of the guide shell 13, so that the telescopic airbag 7 is inflated and deformed, thereby pushing the slider 4 to move forward in the arc-shaped slide rail 3 toward the top of the arc-shaped slide rail 3, thereby driving the camera 5 fixedly installed at the bottom of the slider 4 to perform a forward scan along the arc surface of the transparent protective cover 2. At the same time, during the forward movement of the slider 4, one end of the traction rope 8 is driven to move synchronously, thereby driving the traction rope 8 to pull the reel 10 to rotate and pay out the line, thereby driving the elastic energy storage element to store energy through the fixed axis of the reel 10.

[0069] When the gear 15 moves in the smooth section of the rack 20, the gear 15 and the centrifugal blade 14 stop rotating and no longer inflate the telescopic airbag 7. The elastic energy storage element releases the stored elastic potential energy, thereby driving the reel 10 to rotate in the opposite direction through the fixed shaft, thereby winding the traction rope 8, and pulling the slider 4 along the arc-shaped slide rail 3 in the opposite direction to reset, thereby driving the camera 5 to perform reverse scanning along the arc-shaped surface of the transparent protective cover 2, and the telescopic airbag 7 is pressurized and exhausted when the slider 4 moves in the opposite direction.

[0070] Through the alternating action of forward drive and energy storage reset reverse drive, the camera 5 is able to perform periodic reciprocating motion on the arc slide 3, and the movable seat 9 is moved along the annular track 6 and drives the arc slide 3 to perform circumferential motion around the circular exhibition stand 1, thereby completing the panoramic shooting of the model on the circular exhibition stand 1 without blind spots, and the shooting picture is enlarged in real time and projected on the display set on the top of the base, so that every detail on the model can be locally enlarged without blind spots, effectively improving the model display effect, and no multiple driving sources are required to drive the moving seat 9 and the slider 4 to move, effectively simplifying the structure and saving production costs, and realizing continuous drive through one driving source, which not only can realize panoramic shooting without blind spots, but also can reduce the nodes where failures occur, reduce the failure rate, and effectively improve the stability of the automatic operation of the entire device, and through the setting of the telescopic airbag 7, the slider 4 is driven to move by pneumatics, which effectively avoids the vibration caused by the impact during the meshing of the gear parts compared to the gear meshing transmission, causing the camera 5 to shake and affect the clarity of the image, and effectively improves the stability of the camera 5 during shooting.

[0071] The telescopic airbag 7 is arranged in a bellows shape, and a continuous V-shaped gap is provided inside and outside the airbag wall. When the telescopic airbag 7 contracts, the V-shaped gap is compressed and deformed to buffer and reduce shock for the camera 5.

[0072] Specifically, by setting the telescopic airbag 7 as a bellows-shaped airbag, the telescopic airbag 7 absorbs kinetic energy through pleat deformation during axial expansion and contraction, thereby providing basic telescopic elasticity to adapt to the reciprocating motion requirements of the slider 4, and when the telescopic airbag 7 contracts, the V-shaped gap is compressed to produce progressive plastic deformation, forming nonlinear damping on the slider 4, thereby converting the impact kinetic energy of the slider 4 into material deformation energy and dissipating vibration energy, effectively suppressing the jitter of the camera 5 caused by sudden stop / start, and improving the stability of the shooting picture.

[0073] Furthermore, the V-shaped gap can disperse stress and effectively avoid stress concentration in a local area of the telescopic airbag 7, thereby reducing the risk of fatigue rupture of the bellows and effectively extending the service life of the telescopic airbag 7.

[0074] The elastic energy storage element includes a spring housing 16 , in which a spring 17 is arranged. The central end of the spring 17 is connected to the fixed axis of the reel 10 , and the outermost end is connected to the inner wall of the spring housing 16 .

[0075] The expansion and deformation of the telescopic airbag 7 pushes the slider 4 to move toward the top along the arc-shaped slide rail 3. The traction rope 8 pulls the reel 10 to rotate, and drives the mainspring 17 to tighten and deform and store elastic potential energy.

[0076] Specifically, when the gear 15 moves in the tooth segment of the rack 20, the telescopic airbag 7 is inflated and deformed, thereby pushing the slider 4 to move forward in the arc-shaped slide rail 3 toward the top of the arc-shaped slide rail 3, thereby driving the camera 5 fixedly installed at the bottom of the slider 4 to perform a forward scan along the arc-shaped surface of the transparent protective cover 2. At the same time, during the forward movement of the slider 4, one end of the traction rope 8 is driven to move synchronously, thereby driving the traction rope 8 to pull the reel 10 to rotate and pay out the line, thereby driving the mainspring 17 to tighten and deform through the fixed axis of the reel 10 and store elastic potential energy.

[0077] The mainspring 17 releases elastic potential energy and drives the reel 10 to rotate in the opposite direction to reel in the traction rope 8 and pull the telescopic airbag 7 to shrink and deform.

[0078] Specifically, when the gear 15 moves in the smooth section of the rack 20, the gear 15 and the centrifugal blade 14 stop rotating and no longer inflate the telescopic airbag 7. The spring 17 restores its deformation and releases the stored elastic potential energy, thereby driving the reel 10 to rotate in the opposite direction through the fixed axis, thereby reeling in the traction rope 8, and pulling the slider 4 in the opposite direction along the arc-shaped slide rail 3 to reset through the traction rope 8, thereby driving the camera 5 to perform reverse scanning along the arc-shaped surface of the transparent protective cover 2.

[0079] An air cavity 18 is provided in the slider 4 , and an elastic plug 19 is elastically provided in the air cavity 18 . When the slider 4 moves to contact the top inner wall of the arc-shaped slide rail 3 , the elastic plug 19 is elastically compressed to buffer and reduce shock on the slider 4 .

[0080] Specifically, since the slider 4 is prone to hit the slide rail due to inertia at the end of the stroke, causing the camera 5 to have a blurred image, an elastic plug 19 and an air cavity 18 are provided. When the slider 4 moves to contact the top inner wall of the arc-shaped slide rail 3, the elastic plug 19 first contacts the top inner wall of the arc-shaped slide rail 3 until the slider 4 contacts the top inner wall of the arc-shaped slide rail 3. During the process, the elastic plug 19 is elastically deformed by compression, dissipating residual kinetic energy and suppressing rebound vibration. At the same time, the elastic plug 19 moves in the air cavity 18 and compresses the air in the air cavity 18, thereby forming a high-pressure air cushion, converting rigid collision into flexible damping, reducing peak impact force, thereby achieving precise shock absorption at the end stroke of the slider 4, further suppressing the jitter generated by the camera 5, and improving the stability of the captured image.

[0081] Shock-absorbing bags 21 are symmetrically arranged on the contact surface between the slider 4 and the bottom outer wall of the curved slide rail 3. The shock-absorbing bags 21 are connected to the air cavity 18. The elastic plug 19 elastically compresses and adjusts the air pressure compression in the air cavity 18 to inflate the shock-absorbing bags 21 and eliminate the gap between the contact surface of the slider 4 and the bottom outer wall of the curved slide rail 3.

[0082] Specifically, the elastic plug 19 moves in the air cavity 18 and compresses the air in the air cavity 18, and compresses the air into the shock-absorbing bag 21 through the air channel connected between the air cavity 18 and the shock-absorbing bag 21. The shock-absorbing bag 21 is inflated and deformed to bulge, filling the assembly gap between the slider 4 and the bottom outer wall of the arc-shaped slide rail 3, eliminating shaking noise, and improving the movement stability of the camera 5. The bulged shock-absorbing bag 21 forms an elastic air cushion layer, thereby dispersing collision stress, avoiding hard contact, and extending the life of the arc-shaped slide rail 3. It also constitutes a full-path anti-vibration system with the V-shaped gap during the movement process and the end point of the stroke, effectively improving the stability of the camera 5 during movement and effectively improving the shooting clarity of the camera 5.

[0083] A rubber pad is provided on the surface of the slider 4 on the side away from the telescopic airbag 7 .

[0084] Specifically, the slider 4 is further buffered and shock-absorbed by the provided rubber pad.

[0085] A flow guide pipe 11 is provided between the flow guide housing 13 and the telescopic airbag 7 . The cross-sectional area of the flow guide pipe 11 is gradually reduced from the air inlet to the air outlet.

[0086] Specifically, since the cross-sectional area of the guide tube 11 is tapered from the air inlet to the air outlet, the airflow is accelerated into the telescopic airbag 7 according to the principle that the larger the cross-sectional area, the lower the flow velocity, and the smaller the cross-sectional area, the higher the flow velocity.

[0087] An isolation net is provided on the outer wall of the annular track 6 to connect the guide shell 13 with the outside.

[0088] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
