DETAILED DESCRIPTION

[0038] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments in the following description are only as examples, and other obvious modifications can be thought of by those skilled in the art.

[0039] In the prior art, the night imaging device usually adopts a fixed structure, an internal lamp column is arranged for image display, or relies on electronic sensors, infrared technology and the like to realize imaging. These devices have the problem of folding storage difficulty, resulting in large space occupation and low space utilization; the display form is single, lacks dynamic change, is difficult to attract the attention of the audience, and affects the propaganda effect. For example, the traditional lamp column display can only provide a static picture, cannot adjust the form according to the scene demand, and the device as a whole cannot be retracted, and is easily eroded by the environment for a long time.

[0040] In order to solve the above problems, a foldable mechanical transmission structure needs to be designed, which can not only reduce the space occupation in the non-use state, but also realize multi-angle imaging display through dynamic expansion. By analyzing the telescopic characteristics of the shear fork mechanism, it is found that the height change can be realized by the expansion and contraction of the cross arm, and then the multi-stage shear fork assembly is combined with the imaging device, and the lifting and expansion of the display assembly are controlled by mechanical linkage. At the same time, in order to enhance the visual effect, multiple display units need to be integrated on the mechanical structure, and three-dimensional dynamic pictures are formed through the cooperative movement of different components.

[0041] AsFigures 1 to 9 The imaging device shown in the mechanical transmission structure, comprising a double shear fork mounting base 1 with a mounting platform 101, also comprising:

[0042] The herringbone structure of the shear fork dovetail guide rail 2 is fixed at the top of the double shear fork mounting base 1, and a pair of support seats 9 are symmetrically fixed on the shear fork dovetail guide rail 2 and a pair of sliding seats 3 are symmetrically connected.

[0043] Two first shear control components are symmetrically distributed on both sides of the shear fork dovetail guide rail 2.

[0044] Two second shear control components are respectively hinged with the upper ends of the two first shear control components.

[0045] Symmetrically arranged imaging components are respectively arranged on the two second shear control components.

[0046] The display assembly includes a first display wreath 4, a second display wreath 5, a third display wreath 6, and a display inclined lamp column 7. The second display wreath 5 and the third display wreath 6 are respectively located on both sides of the first display wreath 4, and the display inclined lamp column 7 is arranged at the back side of the first display wreath 4.

[0047] In implementation, the double shear fork mounting base 1 refers to a support structure composed of two groups of cross shear arms, which can be formed by welding metal plates to form a mounting platform 101 for bearing the upper components and dispersing the load. The shear fork dovetail guide rail 2 refers to a herringbone-shaped guide structure at the top, which can realize the directional movement of the sliding seat 3 by matching the dovetail groove with the sliding block, and ensure the stability during symmetrical unfolding. The first shear control component refers to a shear lifting mechanism symmetrically distributed on both sides of the guide rail, which can control the unfolding angle of the shear arm by hydraulic drive, and drive the sliding seat 3 to move along the guide rail. The second shear control component refers to a secondary lifting mechanism hinged with the first shear control component, which can realize multi-stage linkage by cooperating with the magnetic attraction piece 14 and the hydraulic cylinder, and adjust the height and unfolding range of the imaging component. The display inclined lamp column 7 refers to an inclined lighting unit, which can be combined with LED light strips and transparent acrylic columns, and can form a three-dimensional light and shadow effect by adjusting the angle.

[0048] Specifically, the double scissor mounting base 1 provides stable support through the cross structure of two groups of scissor arms, and is used for fixing the scissor dovetail guide rail 2. When the first scissor control assembly is started, the hydraulic cylinder pushes the scissor arms to expand, drives the sliding seat 3 to move along the guide rail to both sides, and synchronously drives the second scissor control assembly to rise. The second scissor control assembly further adjusts the expansion angle of the imaging assembly through the cooperation of the magnetic attraction piece 14 and the hydraulic cylinder. The imaging assembly rises and falls with the scissor structure, drives the first display wreath 4, the second display wreath 5 and the third display wreath 6 to form a layered expansion effect, and the display inclined lamp column 7 projects light through the inclination angle, and cooperates with the expansion action of the wreath to form a dynamic image. In the storage state, the scissor arms are retracted to drive the sliding seat 3 to reset, and the imaging assembly and the display unit are folded above the double scissor mounting base 1, thereby reducing the overall space occupation. In actual application, a square foundation pit can be opened on the horizontal ground as a fan screen storage pit to store the device.

[0049] Compared with the prior art, the existing device usually relies on fixed lamp posts or electronic screens for static display, and cannot realize the folding storage of the mechanical structure. The scheme realizes the expansion or contraction of the imaging assembly and the display unit according to the needs through the linkage control of the scissor mechanism, solves the problem of space occupation, and enhances the visual attraction through the dynamic cooperation of the multi-layer wreath and the inclined lamp column. In addition, the symmetrical sliding design of the scissor dovetail guide rail 2 avoids the deviation problem that may be caused by the traditional single-axis guide, and ensures the stability of the expansion process.

[0050] Through the above technical scheme, the folding storage of the imaging device is realized, and the space occupation in the non-use state is significantly reduced. Through the linkage control of the multi-stage scissor mechanism, the display assembly can form a layered expansion dynamic effect, and the light projection of the inclined lamp column can improve the visual impact and the propaganda effect. The application of the mechanical transmission structure reduces the dependence on external sensors, and enhances the environmental adaptability and reliability of the device.

[0051] As an embodiment of the utility model, the first scissor control assembly comprises:

[0052] The first double scissor lifting mechanism 8 is an X-shaped cross structure composed of five groups of front and rear symmetrical first scissor arms 801, and the lowermost four scissor walls of the first double scissor lifting mechanism 8 are respectively hinged with a pair of support seats 9 and a pair of sliding seats 3 on the same side;

[0053] The two pairs of front and rear symmetrical first hydraulic cylinders 10 are hinged with the same hinge pin shaft on the first double scissor lifting mechanism 8 through the piston rod ends, one pair of the first hydraulic cylinders 10 is hinged on the top of the double scissor mounting base 1, and the other pair of the first hydraulic cylinders 10 is hinged on the top of the mounting platform 101.

[0054] In implementation, the first double scissor lifting mechanism 8 refers to a multi-stage linkage structure composed of five groups of first scissor arms 801 in an X-shaped cross manner, and specifically, the cross arms can be made of high-strength alloy material and are movably connected through a hinge pin, and the multiple groups of first scissor arms 801 form a telescopic structure to extend the lifting stroke. The composite hinge point formed by the support seat 9 and the sliding seat 3 refers to the matching mode of two groups of fixed support points and two groups of movable support points, and the sliding seat 3 can move transversely along the scissor swallow tail guide rail 2, and the movement track of the scissor arms is constrained through the double support points. The upper and lower staggered arrangement of the two pairs of first hydraulic cylinders 10 refers to that the two pairs of first hydraulic cylinders 10 are respectively installed on the top of the double scissor mounting base 1 and the top of the mounting platform 101, and specifically, a double-rod hydraulic cylinder can be used as a power source to synchronously push the hinge pins of different levels through the piston rod.

[0055] Specifically, the five groups of X-shaped cross structures form a telescopic unfolded form, and the cross angle of each group of scissor arms is adjusted through the stroke control of the first hydraulic cylinder 10. The lower four first scissor arms 801 are respectively hingedly connected with the support seat 9 and the sliding seat 3 to form double constraints, and when the sliding seat 3 moves along the guide rail during lifting, the two groups of fixed support points and movable support points jointly control the unfolding angle of the first scissor arms 801.

[0056] Compared with the prior art, the traditional scissor lifting mechanism usually adopts a single X-shaped structure matched with a single hydraulic cylinder for driving, and has defects of limited unfolding stroke and unstable movement track. The present scheme constructs a multi-level linkage system through five groups of X-shaped scissor arms, so that the lifting stroke is expanded to several times of the traditional structure.

[0057] Through the above technical scheme, the folding storage function of the imaging device is realized, and in the non-use state, each first scissor arm 801 can be completely folded into the interior of the foundation pit, and the overall volume is compressed to one third of the unfolded state. The multi-level first scissor arm 801 structure forms a stable track during lifting, eliminates the shaking phenomenon of the traditional single-stage scissor mechanism, and makes the imaging assembly maintain a stable posture during height adjustment.

[0058] As an embodiment of the present application, one side of the X-shaped cross structure composed of each group of first scissor arms 801 is provided with an H-shaped guide wheel 11, and the top of the double scissor mounting base 1 is provided with four steel plates 12 for sliding the H-shaped guide wheel 11.

[0059] In implementation, the H-shaped guide wheel 11 refers to a rolling component with an H-shaped cross-sectional profile, which forms a constraint contact with the edge of the steel plate 12 through a groove during rolling, and can effectively limit the transverse displacement. The four steel plates 12 refer to guide rails arranged in parallel on the top of the base, which can be realized by using a cold-rolled steel plate 12 with a thickness of 3-5 mm, and the surface of the steel plate 12 can be hardened.

[0060] Specifically, when the first double scissor lifting mechanism 8 performs the telescopic movement, the H-shaped guide wheel 11 rolls along the surface of the steel plate 12. The center reinforcing rib of the H-shaped guide wheel 11 is aligned with the central axis of the steel plate 12, and the side walls of the groove keep a gap of 0.5-1.5mm with the edges of the steel plate 12.

[0061] Through the above technical scheme, the application solves the stability problem caused by friction during the movement of the scissor mechanism, and reduces the movement resistance through the rolling contact of the guide wheel and the steel plate 12.

[0062] As an embodiment of the utility model, the second scissor control assembly comprises:

[0063] The second double scissor lifting mechanism 13 is an X-shaped cross structure composed of five groups of second scissor arms 1301 symmetrically arranged in front and back, and the four second scissor arms 1301 at the lowermost end are respectively hinged to the end of the uppermost first scissor arm 801 of the first double scissor lifting mechanism 8.

[0064] The magnetic attraction piece 14 is hinged to the end of one of the second scissor arms 1301 in the uppermost X-shaped cross structure.

[0065] The second hydraulic cylinder 15 is hinged to the side wall of the other second scissor arm 1301 in the uppermost X-shaped cross structure, and the end of the piston rod of the second hydraulic cylinder 15 is hinged to the side wall of the magnetic attraction piece 14.

[0066] In implementation, the second double scissor lifting mechanism 13 refers to a multi-stage X-shaped linkage structure formed by the intersection of five groups of second scissor arms 1301, which can be realized by connecting multiple groups of cross arms with hinge pins, and the overall telescopic bending shape can be changed by controlling the position of the cross node. The magnetic attraction piece 14 refers to a component that can be quickly attracted or separated by magnetic force, which can be realized by an electromagnet or a permanent magnet structure, and in the unfolded state, it forms a magnetic attraction lock with the adjacent component to enhance stability. The second hydraulic cylinder 15 refers to an actuating element that provides push-pull power through hydraulic drive, which can be realized by a single-acting or double-acting hydraulic cylinder structure, and avoids interference with the unfolding path of the second scissor arm 1301 through lateral hinging.

[0067] Specifically, the X-shaped cross structure formed by the five groups of second scissor arms 1301 forms a telescopic linkage frame through the hinge points, and when the first double scissor lifting mechanism 8 performs the lifting action, the second scissor arms 1301 are synchronously expanded or contracted through the hinge transmission of power. The piston rod of the second hydraulic cylinder 15 pushes the magnetic attraction piece 14 to displace, and when expanded to the position, the magnetic attraction piece 14 is adsorbed with the corresponding part to form a rigid fixation, and when contracted, the second hydraulic cylinder 15 moves reversely to release the magnetic attraction locking, so that the overall structure can be folded and stored. The laterally hinged second hydraulic cylinder 15 applies a lateral thrust to the second scissor arm 1301, enhances the control accuracy of the magnetic attraction piece 14 by using the lever principle, and at the same time avoids the motion interference of the second scissor arm 1301 during the extension and contraction process.

[0068] Through the above technical scheme, the application solves the problem of inconvenient folding and storage of the night imaging device, realizes rapid expansion and contraction of the device through multi-stage scissor linkage and magnetic attraction cooperative control, and reduces the occupied space in the non-use state. The display form can be dynamically changed by adjusting the extension and contraction amplitude of the scissor mechanism, and the stability in different forms is ensured by cooperating with the magnetic attraction locking mechanism, so that the display effect is improved and the attraction is improved.

[0069] As an embodiment of the utility model, the imaging assembly includes five telescopic rails 16 with mounting seats 1601, and the five telescopic rails 16 are arranged on the hinge shafts of the X-shaped cross structure formed by the five groups of second scissor arms 1301 respectively, and the mounting seat 1601 of each telescopic rail 16 is provided with an imaging mechanism.

[0070] In implementation, the telescopic rail 16 refers to a guide structure that can change the length in the axial direction, and the telescopic characteristic allows the extension range of the imaging mechanism to be adjusted when the second scissor arm 1301 is expanded or folded, so as to adapt to the space requirement of different display forms.

[0071] The mounting seat 1601 refers to a support part fixed to the hinge shaft and bearing the imaging mechanism, which can be realized by a metal base with a bolt locking structure, and the rigid connection with the hinge shaft ensures that the imaging mechanism maintains a stable posture when the second scissor arm 1301 moves. The hinge shaft refers to the rotation center shaft connecting adjacent second scissor arms 1301, which can be realized by a steel pin shaft with self-lubricating bearing, and the position change directly reflects the expansion angle of the scissor arm, providing a reference point for the synchronous displacement of the imaging mechanism. The imaging mechanism refers to a component for generating dynamic visual effects, which is installed at the end of the telescopic rail 16 and can realize multi-angle imaging according to the telescopic amount of the telescopic rail 16 and the displacement of the hinge shaft.

[0072] Specifically, when the X-shaped cross structure formed by the second scissor arm 1301 is deformed due to the driving of the scissor lifting mechanism, the relative positions of the five groups of hinged shafts change, driving the telescopic guide rails 16 mounted thereon to move synchronously. Since each telescopic guide rail 16 is independently arranged at the corresponding hinged shaft node, its telescopic amount can be adjusted according to the unfolding degree of the second scissor arm 1301, for example, elongated to expand the imaging coverage range in the fully unfolded state, and shortened to reduce the occupied space when folded and stored. The fixed connection of the mounting seat 1601 and the hinged shaft ensures that the imaging mechanism always follows the node motion trajectory, ensuring that the imaging direction is consistent with the overall deformation of the scissor structure.

[0073] As an embodiment of the utility model, the imaging mechanism comprises a rotating plate 17, which is rotatably connected to the mounting seat 1601, and a square tube 18 is fixedly connected to the rotating plate 17. The side wall of the square tube 18 is fixedly installed with a first fan screen 19 and a second fan screen 20. A rotating part is arranged on the mounting seat 1601, and the rotating part is used to drive the rotating plate 17 to rotate by ninety degrees.

[0074] In implementation, the rotating plate 17 refers to a rigid flat plate rotatably connected to the mounting seat 1601, which can specifically adopt an aluminum alloy plate to realize rotatable connection through a hinge, and the rotating axis is parallel to the surface of the mounting seat 1601. The space position adjustment of the imaging assembly is realized through the structure. The square tube 18 is used to provide a support surface perpendicular to the plane of the rotating plate 17, to ensure the mounting stability of the first fan screen 19 and the second fan screen 20. The first fan screen 19 and the second fan screen 20 refer to rotating display devices with LED light sources, and the complementary imaging areas are formed through the symmetrical arrangement of the two screens. The rotating part refers to a power mechanism for driving the rotating plate 17 to rotate, and the ninety-degree positioning is realized through accurate control of the rotating angle. The ninety-degree rotation refers to the range of the rotating angle of the rotating plate 17 between the storage state and the working state, and the rotating end position control can be realized through a limit switch or an angle sensor, to facilitate folding and storage.

[0075] Specifically, the rotating plate 17 is rotatably connected to the mounting seat 1601 through a hinge shaft and rotates in the plane around the hinge shaft under the driving of the rotating part. When the rotating plate 17 is rotated to a ninety-degree angle with the mounting seat 1601, the square tube 18 fixed to the surface thereof drives the first fan screen 19 and the second fan screen 20 to expand to the working position synchronously, and the two screens form a horizontal symmetrical layout, to generate a stereoscopic imaging effect through dynamic light source changes. In the non-working state, the rotating part drives the rotating plate 17 to rotate reversely by ninety degrees, so that the square tube 18 and the fan screens are parallel to the surface of the mounting seat 1601, to realize the folding and storage of the overall structure. The power output of the rotating part is converted into the angular displacement of the rotating plate 17 through a mechanical transmission structure, and the limit mechanism is used to ensure the accuracy of the rotating angle.

[0076] Compared with the prior art, the existing night imaging device usually adopts a fixed lamp post or an electronic display screen, the spatial position of the imaging unit cannot be adjusted, and the overall volume of the equipment cannot be compressed. The imaging unit can be folded in the vertical direction through the cooperation of the rotating plate 17 and the rotating part, so that the horizontal space occupation is reduced. Meanwhile, the double-fan screen forms a spatial staggered layout when it is unfolded, and compared with a single plane display screen, the double-fan screen can generate dynamic visual effects through light source superposition.

[0077] Through the above technical scheme, the warehouse and transportation space occupation is effectively reduced, and meanwhile, the double-fan screen forms hierarchical display areas through angle adjustment when it is unfolded, and dynamic imaging changes are generated by cooperating with the rotating light source, so that the visual attraction is enhanced. The mechanical transmission structure avoids the use of a complex electronic control system, and the reliability of the rotating positioning is improved.

[0078] As an embodiment of the utility model, the imaging mechanism further comprises:

[0079] The connecting rod 21 is rotatably connected to the side wall of the square tube 18, and the end of the connecting rod 21 is fixedly connected with the third fan screen 22;

[0080] The support seat 23 is fixedly connected to the side wall of the square tube 18, and the support seat 23 is hingedly connected with the telescopic push rod 24, and the piston rod end of the telescopic push rod 24 is hingedly connected with the side wall of the connecting rod 21.

[0081] In implementation, the connecting rod 21 refers to a rod-shaped component with two ends connected with the square tube 18 and the third fan screen 22 respectively, which can be realized by a metal rod with a rotating shaft, and the spatial position of the third fan screen 22 is changed by rotation. The third fan screen 22 refers to a display unit installed at the end of the connecting rod 21, which can be realized by an LED light bar or a rotating light emitting device, and is used to expand the display area of the imaging mechanism. The support seat 23 refers to a bearing structure fixed to the side wall of the square tube 18, which can be realized by a metal base fixed by welding or bolts, and provides an installation fulcrum for the telescopic push rod 24.

[0082] Specifically, when the piston rod of the telescopic push rod 24 performs telescopic movement, the connecting rod 21 is rotated around the hinged point of the connecting rod 21 and the square tube 18, so as to drive the third fan screen 22 to move along an arc-shaped track. The position change of the third fan screen 22 enables the third fan screen 22 to fill the gap between the first fan screen 19 and the second fan screen 20, and form a display surface with a larger coverage range. The design that the support seat 23 is fixed to the side wall of the square tube 18 avoids interference with the rotation freedom of the rotating plate 17, and ensures the stability of the force transmission path of the telescopic push rod 24. The rotation angle of the connecting rod 21 is controlled by the stroke length of the telescopic push rod 24, and the third fan screen 22 is switched between the horizontal and inclined states.

[0083] Compared with the prior art, the display unit of the conventional imaging device is usually fixedly installed on a support and cannot be adjusted in relative position or angle, resulting in single display effect. The third fan screen 22 can be dynamically adjusted in position by cooperation of the connecting rod 21 and the telescopic push rod 24, so that a multi-level three-dimensional display effect is formed with the first fan screen 19 and the second fan screen 20.

[0084] By the technical scheme, the application solves the problem of fixed display angle and position of the prior art, realizes dynamic adjustment of the spatial position of the third fan screen 22, and expands the coverage range of the display area. The moving track of the third fan screen 22 fills the gap between adjacent fan screens, eliminates the display blind area, and forms a continuous and changeable image combination.

[0085] As an embodiment of the application, the rotating member comprises:

[0086] The rotating rod 25 is fixed on the mounting seat 1601.

[0087] The electric push rod 26 is rotatably connected to the surface of the rotating rod 25, and the piston rod end of the electric push rod 26 is rotatably connected with the linkage pin 27, which is rotatably connected to the top of the rotating plate 17.

[0088] In implementation, the rotating rod 25 refers to a rigid rod-shaped component as a support base, which can be specifically implemented by a hollow metal round pipe welded and fixed with the mounting seat 1601 to form a stable rotating support point in the device. The cylinder end of the electric push rod 26 is rotatably connected with the rotating rod 25 through a bearing. The linkage pin 27 refers to a transmission component connecting the electric push rod 26 and the rotating plate 17, which can be specifically implemented by a pin shaft assembly with a self-lubricating bushing to form a non-central hinged point on the top of the rotating plate 17.

[0089] Specifically, when it is necessary to switch between unfolding and folding, the electric push rod 26 performs telescopic movement according to a control signal, and the piston rod drives the linkage pin 27 to displace along a straight line. Since the linkage pin 27 is hinged at the edge position of the rotating plate 17, the linear thrust is converted into a rotary torque of the rotating plate 17 around the axis of the mounting seat 1601. During rotation, the cylinder of the electric push rod 26 rotates synchronously around the axis of the rotating rod 25 to form a double-degree-of-freedom movement mechanism. This linkage mechanism enables the rotating plate 17 to realize precise ninety-degree angular displacement, ensures that the fan screen and the display garland maintain the best display angle in the unfolded state, and rotates the fan screen to the vertical direction of the mounting seat 1601 in the folded state to realize compact folding.

[0090] By the technical scheme, the application realizes precise electric control adjustment of the rotating angle of the imaging mechanism, effectively improves the dynamic presentation effect of the display device, and ensures the homogeneity of the returning of each component during folding and folding, thereby solving the problem of low utilization rate of the folding space caused by angle deviation of the conventional device.
