Description

Technical Field

[0001] The invention relates to the technical field of special optical advertising equipment, and in particular to a dynamic guide sign. Background Art

[0002] In modern public spaces, exhibition halls, transportation hubs, and other locations, dynamic signage systems play a vital role in information transmission and visual guidance. Traditional static signage is limited by its limited information transmission and lack of visual appeal. For example, patent application number "CN201410619226.X" proposes a "three-dimensional dynamic signage composed of arc patterns." The pattern on the signage is composed of numerous arcs, which, when illuminated by light, can display an image with a three-dimensional dynamic effect. The center of each arc on the signage is located at the sampling point of the image to be displayed. Different arc radii can display images at different levels; different arc starting and ending angles can display two or more images. However, such signs are static displays and cannot produce dynamic visual effects. Although computer vision has attempted to simulate three-dimensional effects through binocular stereo matching algorithms or optical materials (such as the special pigments mentioned above), these solutions require complex image processing equipment or specific lighting conditions, resulting in high implementation costs and difficulty in application in outdoor guidance scenarios. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the present invention provides a dynamic guide sign that overcomes the deficiencies of the prior art, has a reasonable design, a compact structure, can be dynamically moved, produces a three-dimensional perspective effect, and plays a novel indicating role.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] A dynamic guide sign, comprising:

[0006] Stand;

[0007] A main shaft extending through the frame and rotatably connected to opposite sides of the frame;

[0008] A driving member for driving the main shaft to rotate;

[0009] A fixed shaft running through the frame and fixedly connected to both sides of the frame;

[0010] A plurality of linkage components, which include a rotating rod rotatably connected to a fixed shaft, an eccentric wheel eccentrically fixedly connected to the main shaft rod, a push rod hinged to the upper end of the rotating rod, a movable block fixed to the upper end of the push rod, an arm rod rotatably connected to both sides of the movable block, a connecting shaft fixedly connected between the ends of the two arm rods, a short rod fixed to the rear side of one of the arm rods, and a pull rod with both ends hinged to the end of the short rod and the surface of the platform respectively. The lower side of the rotating rod contacts the surface of the eccentric wheel and rotates up and down around the fixed shaft as the eccentric wheel rotates; a sign is fixedly connected to the connecting shaft.

[0011] Preferably, a limiting slit is provided on the upper surface of the platform, and both sides of the push rod are limited by the limiting slit so that the push rod can move up and down in a vertical plane.

[0012] Preferably, the centers of all the eccentric wheels are coaxially located on a theoretical cylindrical surface coaxial with the main shaft, and the positions of the eccentric wheels connected from one end of the main shaft to the other end are sequentially unidirectionally arranged around the theoretical cylindrical surface to form a spiral shape.

[0013] Preferably, the phase angle difference between adjacent eccentric wheels is 15°-30°.

[0014] Preferably, a plurality of slots are provided on the front side of the stand, each slot being correspondingly arranged under each sign, and metal reeds of different lengths are connected in sequence in each slot, and a striking rod is fixedly connected under the sign, and when the sign rotates to the bottom, each of the striking rods strikes metal reeds of different lengths, exciting different fundamental frequency vibrations and emitting sounds of different frequencies.

[0015] Preferably, a fixing plate is fixedly connected inside the stand, a plurality of square slots are opened on the upper end of the fixing plate, the fixing shaft passes through all the square slots, and the tail of the rotating rod extends into the square slot and is rotatably connected to the fixing shaft.

[0016] Preferably, the driving member is a motor arranged on one side of the platform, and the main shaft is coaxially fixedly connected to the output end of the motor; or, the driving member is a wind blade, and the wind blade is assembled on the shaft end of the main shaft.

[0017] Preferably, a display screen with an external power supply is provided on the surface of the sign, or a hollow logo pattern is provided on the surface of the sign.

[0018] The present invention provides a dynamic guide sign with the following beneficial effects:

[0019] The present invention drives the main shaft to rotate through a driving member, and the contact position between the eccentric wheel and the end of the rotating rod is periodically displaced. This displacement is transmitted through the contact surface at the lower end of the rotating rod and converted into the angular displacement of the rotating rod around the fixed axis. The upper end of the rotating rod pushes the push rod to form a vertical reciprocating motion under the constraint of the limiting slit. The spirally distributed eccentric wheel group produces an axial phase delay, which causes a time difference in the motion state of adjacent signs. The sign group reaches the trajectory vertex in sequence, forming a mechanical wavefront that propagates along the axial direction. When the driving member drives the sign group to move at a frequency of 15-25Hz, the observer observes from the main shaft axial perspective and perceives continuously propagating wave peaks rather than discrete signs, presenting a continuous undulating three-dimensional motion effect, forming a motion perspective effect, and observing three-dimensional stereoscopic vision, which plays a novel guiding role.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0025] Refer to the attached Figure 1-Figure 3A dynamic guide sign includes a stand 1 as a bearing body, a limited slit 11 is processed on the upper surface of the stand 1, and a fixed plate 13 with a plurality of square grooves 131 is fixed inside. The main shaft 2 passes through the two opposite side walls of the stand 1 and is configured with bearings connected to the stand 1 to achieve a rotational connection relative to the stand 1. The main shaft 2 is driven by a driving member 3. Specifically, the driving member 3 can be configured as a motor with an output end coaxially fixedly connected to the main shaft 2, or configured as a wind blade assembled and connected to the axial end of the main shaft 2 to utilize wind power for driving. A fixed shaft 4 passes through the stand 1, and both sides of the fixed shaft 4 are fixedly connected to the stand 1. Specifically, the fixed shaft 4 passes through all the square grooves 131 of the fixed plate 13 horizontally and is welded to the stand 1.

[0026] Several linkage assemblies 5 are spaced and arranged in parallel along the axial direction of the main shaft 2. Each linkage assembly 5 includes an eccentric 52 fixedly connected (via a keyway or bolt connection) to the main shaft 2. The centers of all eccentrics 52 are co-located on a theoretical cylindrical surface coaxial with the main shaft 2, and are sequentially arranged in a spiral phase pattern along the axial direction of the main shaft 2 (i.e., the positions of the eccentrics 52 connected from one end of the main shaft 2 to the other are sequentially arranged in a unidirectional spiral around the theoretical cylindrical surface). The phase angle difference between adjacent eccentrics is 15°-30°. The linkage assembly 5 also includes a rotating rod 51, the tail of which extends into the square slot 131 and is rotatably connected to the fixed shaft 4. The free end of the rotating rod 51 is curved, and the curved free end maintains linear contact with the outer peripheral surface of the eccentric 52. A push rod 53 is hingedly connected to the upper end of the rotating rod 51. The rod body of the push rod 53 is limited by limiting slits 11 provided on the surface of the platform 1, which constrain the push rod 53 to move within the vertical plane. A movable block 54 is fixedly connected to the upper end of the push rod 53. A pair of arm rods 55 are symmetrically connected to the movable block 54 on both sides via a pin, and the ends of the two arm rods 55 are fixedly connected by a connecting shaft 56. A short rod 57 is fixedly connected to the rear side of one of the arm rods 55. In addition, a pull rod 58 is provided, with its ends hinged to the ends of the short rod 57 and to a predetermined connection point on the surface of the platform 1. A sign 59 is rigidly fixed to the connecting shaft 56.

[0027] Working Principle: When the driving member 3 outputs torque to rotate the main shaft 2, the contact position between the eccentric wheel 52 and the end of the rotating rod 51 periodically shifts. This displacement is transmitted through the contact surface at the lower end of the rotating rod 51, converting it into angular displacement about the fixed axis 4. The upper end of the rotating rod 51 pushes the push rod 53, resulting in vertical reciprocating motion within the constraints of the limiting slit 11. When the push rod 53 moves upward, the movable block 54 moves vertically upward, driving the two arms 55 to rise synchronously. The pull rod 58 pulls the arms 55, causing the front ends of the arms 55 to rotate around the pin connecting them to the movable block 54. The connecting shaft 56 combines the vertical and angular displacements, causing the sign 59 to rise diagonally along a parabolic trajectory in space, achieving an elevated display posture. When the push rod 53 moves downward, the weight of the movable block 54 and the gravity of the arms 55 reset the mechanism. The tension of the pull rod 58 maintains the rotational stability of the arms 55, and the sign 59 descends diagonally along its original trajectory to its initial position. In this embodiment, the spirally arranged eccentrics 52 produce an axial phase delay, resulting in a time difference in the motion of adjacent signs 59. As the spindle 2 rotates, the signs 59 sequentially reach the apex of their trajectory, forming a wave-like visual pattern that propagates axially. When the driver 3 drives the signs 59 at a frequency of 15-25 Hz, an observer observing from the spindle's axial perspective perceives a continuous wave of peaks rather than discrete signs 59, creating a continuous, undulating, three-dimensional motion effect. This creates a perspective effect, allowing for a three-dimensional visual experience and providing a novel guidance function.

[0028] The surface of the sign 59 can be provided with a display screen connected to an external power supply to switch between different display patterns. Alternatively, a hollow logo pattern can be stamped on the surface of the sign 59 and used with wind blades as the driving element 3 to achieve a three-dimensional visual observation effect without consuming electricity.

[0029] As an embodiment of the present invention, a plurality of slots 12 are provided on the front side of the stand 1, and each slot 12 is respectively arranged under each sign 59. Metal reeds 6 of different lengths are connected in sequence in each slot 12, and a striking rod 7 is fixedly connected under the sign 59. When the sign 59 rotates to the bottom, each striking rod 7 strikes the metal reeds 6 of different lengths, exciting different fundamental frequency vibrations and emitting sounds of different frequencies, thereby generating recognizable harmonic sequence sounds, which have both information prompting and visually impaired assistance functions.
