Description

Technical Field

[0001] This utility model relates to the field of teaching aids and toys, specifically to a dynamic flying deer device based on rack and pinion and incomplete gears. Background Technology

[0002] Currently, mechanical demonstration teaching aids, deer-shaped toys, and craft gifts on the market all have significant shortcomings in terms of structural functionality and multi-purpose integration. On the one hand, existing mechanical teaching aids are primarily functional, with relatively rough designs and a lack of artistic and lifelike expression, making them difficult to attract non-professional users or teenagers. Meanwhile, while some electric toys with dynamic effects can achieve certain movement functions, their highly integrated and closed internal structures are unsuitable for teaching demonstrations, and their structural stability and ease of maintenance are insufficient. On the other hand, existing deer toys are mainly plastic dolls or plush toys, lacking realistic mechanical movements and unable to achieve coordinated movements of the head, body, and limbs. At the same time, existing craft gifts often emphasize exquisite shapes and decorations, but generally neglect mechanical interactive functions.

[0003] In the prior art, Chinese patent document CN206262082U discloses a Pegasus toy, which includes a horse body, a first front leg, a second front leg, a first hind leg, a second hind leg, a driven wheel, a power mechanism, a linkage assembly, wings, and horse eyes. A crank handle drives a drive gear, which meshes with the driven wheel to rotate. Cranks on both sides of the driven wheel drive the limbs and lower legs to move through multiple independent linkages, simulating galloping. At the same time, the cranks drive a sliding shaft to extend and retract through linkages, and the sliding shaft drives the wings on both sides to flap. When the sliding shaft moves to the bottom of the sliding hole, it triggers a contact switch, causing the bulbs in the horse eyes to flash. Chinese patent document CN207624339U discloses a dynamic art mechanical device, which includes a main body, front legs, hind legs, wings, transmission gears, a motor, leg transmission links, wing transmission links, and a base. The motor drives the transmission gears to rotate, and the transmission gears, through the leg transmission links, cause the front and hind legs to move relative to the main body, forming a running posture. At the same time, the motor drives the wing transmission links to move, causing the wings to move relative to each other, forming a flying posture.

[0004] However, the two devices mentioned above have the following shortcomings: (1) High structural complexity and insufficient aesthetics: Pegasus toys require 12 sets of linkages to drive the movement of the limbs, and the wings and legs are driven independently, requiring additional sliding shafts and multiple sets of linkages. Dynamic art mechanical kit The structure is quite complex, with the legs and wings using independent linkage systems. Furthermore, the exposed structural components of both components detract from the overall integrity and aesthetics of the design, weakening the realism of the biomimetic form and making it appear cluttered and rigid.

[0005] (2) Insufficient coordination and biomimicry: Both can only drive movement of limited parts, lacking the linkage of complete biological forms, and the body parts are all in a static state, unable to participate in coordinated movement. The Pegasus toy only realizes the basic movements of the limbs and wings, lacking the linkage of the head and tail; the dynamic art mechanical device can only drive the legs to run and the wings to fly, also lacking the movement of key parts such as the head and tail. In the movement of real organisms, the body often coordinates with the limbs, head, tail and other parts to maintain balance and posture, but the body parts of both do not participate in the movement, further aggravating the sense of separation of movement, and failing to fully simulate the coordination of biological movement.

[0006] (3) Poor transmission stability and power efficiency: Both have defects in transmission structure. Pegasus toys rely on manual crank for drive, and the power output is unstable and prone to jamming. Multi-link transmission leads to large force loss. Although the dynamic art mechanical device is driven by a motor, it is only driven by simple gears and linkages without a reducer or motion constraint mechanism, which easily causes motion jamming due to uneven force.

[0007] (4) Complex assembly and low maintenance convenience: The connection methods of both are not conducive to disassembly and maintenance. The connecting rods and legs of the Pegasus toy are fixed by welding, and it is difficult to replace the parts after they are damaged. The fixed bracket and base of the dynamic art mechanical device are fixedly connected in a non-removable manner, and the whole body needs to be disassembled for maintenance. Utility Model Content

[0008] To address the shortcomings of existing mechanical demonstration teaching aids and modeling toys, this utility model proposes a dynamic flying deer device based on rack and pinion and incomplete gears. Through a motor-driven linkage structure, the deer's head, limbs, body and tail can be oscillated periodically, improving the motion coordination and biomimicry of the mechanical demonstration teaching aid.

[0009] To achieve the above-mentioned objectives, the technical solution of this utility model is as follows: This invention proposes a dynamic flying deer device based on a rack and pinion and a non-incomplete gear, including a drive unit and a flying deer main body unit mounted on a base. The drive unit includes a drive mechanism and a linkage mechanism. The drive mechanism includes a power unit and a transmission gear driven to rotate by the power unit. The transmission gear is rotatably connected between two support plates via a gear shaft. The linkage mechanism includes two symmetrically arranged guide rail transmission rods and a rack transmission rod located between the two guide rail transmission rods. The lower ends of the two guide rail transmission rods are respectively connected to the two ends of the gear shaft via eccentric connectors. The lower end of the rack and pinion drive rod is rotatably connected between two support plates via a guide rail fixing link. The main body unit of the flying deer includes an outer shell and a left front leg, a right front leg, a left hind leg, a right hind leg, a deer head mechanism, and a tail mechanism rotatably connected to the outer shell. The upper ends of the two guide rail drive rods are hinged to the outer shell via a top fixing link. The deer head mechanism is coaxially connected to the left and right front legs as a whole, and the tail mechanism is coaxially connected to the left and right hind legs as a whole, and is rotatably mounted on the outer shell. Each of these two wholes is provided with a non-complete gear that meshes with the rack on the rack and pinion drive rod.

[0010] Preferably, the guide rail fixing link passes through the support plate and connects to the guide rail transmission rods on both sides, and the bottom of the guide rail transmission rod has a first sliding groove; the middle of the two guide rail transmission rods is connected to a middle transmission link that passes through the rack transmission rod, and the rack transmission rod has a second sliding groove for the middle transmission link; both ends of the guide rail fixing link and the middle transmission link are connected to bushings by interference fit to restrict the axial movement of the guide rail transmission rods.

[0011] Preferably, the eccentric connector is a crank, with one end of the crank fixedly connected to the gear shaft and the other end rotatably connected to the guide rail transmission rod.

[0012] Preferably, the deer head mechanism and tail mechanism are located at the front and rear ends of the outer shell, respectively, and the left and right hind legs, left and right front legs are symmetrically arranged on the outside of the outer shell.

[0013] Preferably, the power unit includes a DC geared motor, the output end of which is coaxially connected to a drive gear, and the drive gear meshes with a transmission gear for transmission.

[0014] Preferably, the outer shell is symmetrically provided with fixing rings on the left and right sides, and the left wing and right wing are symmetrically rotatably connected to the two fixing rings; the surfaces of the left and right sides of the outer shell are provided with third sliding grooves, the top of the rack and pinion transmission rod is connected to the wing transmission link, the two ends of the wing transmission link extend out of the third sliding grooves on the left and right sides of the outer shell, and are rotatably connected to the corresponding wings by iron wires.

[0015] Preferably, both the deer head mechanism and the tail mechanism include a contouring part and a transmission part. The contouring part is located on the outside of the outer shell, while the transmission part extends into the inside of the outer shell. The transmission part of the deer head mechanism is connected to the left and right front legs as a whole via a first shaft and is rotatably connected to the outer shell. The transmission part of the tail mechanism is connected to the left and right hind legs as a whole via a second shaft and is rotatably connected to the outer shell.

[0018] Preferably, the upper surface of the base inside the rectangular enclosure is provided with an LED light connected to the control board.

[0019] The working principle of this utility model is as follows: The DC geared motor rotates, which drives the drive gear and transmission gear to rotate. The rotation of the transmission gear drives the crank to rotate, causing it to generate periodic circumferential displacement due to eccentricity. This pushes the guide rail transmission rod along the constrained trajectory of the preset first and second slide grooves to complete the reciprocating swing motion. Subsequently, the guide rail transmission rod is connected to the outer shell through a hinged node, driving both to perform planar composite motion synchronously. At this time, the outer shell and the rack transmission rod form relative motion. The rack structure on the surface of the rack transmission rod meshes with the incomplete gears connected to the deer head mechanism and tail mechanism. The linear displacement is converted into rotational motion by means of the gear and rack transmission pair, driving the deer head and tail to swing periodically around the axis. At this time, since the left and right front legs form a coaxial rotation constraint with the deer head mechanism through the first shaft, and the left and right hind legs are coaxially connected with the tail mechanism through the second shaft, the swing of the deer head and tail can be synchronously transmitted to the limbs, achieving coordinated linkage between the head, tail and limbs.

[0028] Example 1 like Figures 1-7 As shown, a dynamic flying deer device based on rack and pinion and incomplete gear includes a base unit, a drive unit, and a flying deer main body unit, with the drive unit and flying deer main body unit both mounted on the base unit.

[0029] like Figure 5 and Figure 6 As shown, the drive unit includes a drive mechanism and a linkage mechanism. The drive mechanism includes a power unit and a transmission gear 8 driven to rotate by the power unit. The transmission gear 8 is rotatably connected between two support plates 5 via a gear shaft 12. In this embodiment, the power unit can be a DC geared motor 6 or a rocker mechanism. In this embodiment, the DC geared motor 6 is bolted to the outer surface of one of the support plates 5. The output shaft of the DC geared motor 6 is coaxially connected to a drive gear 7, which meshes with the transmission gear 8 to achieve transmission.

[0030] The linkage mechanism includes two symmetrically arranged guide rail transmission rods 10 and a rack transmission rod 11 located between the two guide rail transmission rods 10. The lower end of the rack transmission rod 11 is rotatably connected between two support plates 5 via a guide rail fixing link 13. The bottom ends of both guide rail transmission rods 10 are connected to the two ends of the gear shaft 12 via an eccentric connector. Preferably, in this embodiment, the eccentric connector is a crank 9, one end of which is fixedly connected to the gear shaft 12, and the other end is rotatably connected to the guide rail transmission rod 10.

[0031] In this design, the two guide rail transmission rods 10 have identical structures. The lower end of the gear transmission rod is rotatably connected between the two support plates 5 via a guide rail fixing link 13. The two guide rail transmission rods 10 are respectively connected to the sides of the two support plates 5 away from the gear transmission rod. Each of the two guide rail transmission rods 10 has a first groove 29 along its length at its bottom. The two ends of the guide rail fixing link 13 pass through the support plates 5 on both sides and connect to the corresponding first groove 29. Furthermore, a bushing 36 is connected to the end of the guide rail fixing link 13 to restrict the axial movement of the guide rail transmission rod 10. A middle transmission link 14 is connected at the middle position of the two guide rail transmission rods 10. A second groove 30 is formed along the length of the rack transmission rod 11. The middle transmission link 14 passes through the second groove 30 on the rack transmission rod 11 and is connected at both ends to the two guide rail transmission rods 10. Bushings 36 are also connected to both ends of the middle transmission link 14. The first slide groove 29 and the second slide groove 30 mainly serve to limit and guide. Under the action of the crank 9, the guide rail transmission rod 10 drives the middle transmission connecting rod 14 to reciprocate along the second slide groove 30, thereby realizing the periodic change of the relative position between the guide rail transmission rod 10 and the rack transmission rod 11.

[0032] Furthermore, a top fixing link 16 is provided at the top of the two guide rail transmission rods 10, which is used to connect the outer shell 17 in the main body unit of the flying deer.

[0033] like Figure 7 and Figure 8As shown, in this embodiment, the main body unit of the flying deer is a biomimetic structure, which includes a shell 17, a left foreleg 20, a right foreleg 21, a left hind leg 18, a right hind leg 19, a deer head mechanism 24, and a tail mechanism 25. The deer head mechanism 24 and the tail mechanism 25 are located at the front and rear ends of the shell 17, respectively, while the left hind leg 18, right hind leg 19, left foreleg 20, and right foreleg 21 are symmetrically arranged on the left and right sides of the shell 17.

[0034] The deer head mechanism 24 is coaxially and fixedly connected to the left front leg 20 and the right front leg 21, and the tail mechanism 25 is coaxially and fixedly connected to the left hind leg 18 and the right hind leg 19. These two components are rotatably connected to the outer shell 17 via the first shaft 27 and the second shaft 28, respectively. Specifically, both the deer head mechanism 24 and the tail mechanism 25 include a contouring part and a transmission part. The contouring part (i.e., the deer head and tail) is located on the outside of the outer shell 17, while the transmission part extends into the interior of the outer shell 17. The transmission part of the deer head mechanism 24 is connected to the left front leg 20 and the right front leg 21 via the first shaft 27 and is rotatably connected to the outer shell 17; the transmission part of the tail mechanism 25 is connected to the left hind leg 18 and the right hind leg 19 via the second shaft 28 and is rotatably connected to the outer shell 17. The transmission parts of the deer head mechanism 24 and the tail mechanism 25 are provided with incomplete gears that mesh with the rack on the rack transmission rod 11. The upper end of the rack transmission rod 11 extends into the housing 17 and meshes with the incomplete gears of the transmission parts of the deer head mechanism 24 and the tail mechanism 25.

[0035] Preferably, in this embodiment, the top fixed connecting rods 16 of the two guide rail transmission rods 10 are respectively hinged to the left and right sides of the outer shell 17. Under the action of the guide rail transmission rods 10, the relative position between the outer shell 17 and the rack transmission rod 11 changes periodically, so that the incomplete gear of the transmission part rotates around the shaft on the corresponding side under the action of the rack, thereby driving the two parts to move closer to each other or away from each other, achieving the dynamic effect of the flying deer.

[0036] Preferably, in order to facilitate the design, assembly and maintenance of this device, the outer shell 17 can be designed to consist of two split outer shells 17, with the transmission parts of the deer head mechanism 24 and the tail mechanism 25 located between the two split outer shells 17, and the two split outer shells 17 respectively connected to the two guide rail transmission rods 10.

[0037] The driving principle of this device is as follows: The DC geared motor 6 rotates, driving the drive gear 7 and the transmission gear 8 to rotate. The rotation of the transmission gear 8 drives the crank 9 to rotate, causing it to generate periodic circumferential displacement due to eccentricity. This pushes the guide rail transmission rod 10 along the preset constraint trajectory of the first slide groove 29 and the second slide groove 30 to complete the reciprocating swing motion. Subsequently, the guide rail transmission rod 10 is connected to the outer shell 17 through a hinge node, driving the two to perform planar composite motion synchronously. At this time, the outer shell 17 and the rack transmission rod 11 form relative motion. The rack structure on the surface of the rack transmission rod 11 meshes with the incomplete gear connected to the deer head mechanism 24 and the tail mechanism 25. The linear displacement is converted into rotational motion by means of the gear and rack transmission pair, driving the deer head and tail to swing periodically around the axis. At this time, since the left front leg 20 and the right front leg 21 form a coaxial rotation constraint with the deer head mechanism 24 through the first shaft 27, and the left hind leg 18 and the right hind leg 19 are coaxially connected with the tail mechanism 25 through the second shaft 28, the swing of the deer head and tail can be synchronously transmitted to the limbs, achieving coordinated linkage between the head, tail and limbs.

[0038] Example 2 Based on Embodiment 1, furthermore, fixing rings 26 are symmetrically arranged on the left and right sides of the outer shell 17. A left wing 22 and a right wing 23 are symmetrically mounted on the two fixing rings 26, and the left wing 22 and the right wing 23 are rotatably connected to the fixing rings 26 on the corresponding sides. A third sliding groove 31 is opened on the surface of the left and right sides of the outer shell 17. The top of the rack and pinion transmission rod 11 is connected to the wing transmission connecting rod 15. The two ends of the wing transmission connecting rod 15 extend out of the third sliding grooves 31 on the left and right sides of the outer shell 17 and are rotatably connected to the bottom of the wing on the corresponding side through the wire 35.

[0039] The guide rail transmission rod 10 generates periodic displacement in the up and down direction under the drive of the crank 9. When the outer shell 17 moves with the guide rail transmission rod 10, it drives the left wing 22 and the right wing 23 to reciprocate around the fixed ring 26, thereby simulating the dynamic of bionic flapping wings and finally realizing the coordinated movement of multiple mechanisms of the head, tail, limbs and wings.

[0040] Example 3 Based on Example 1, further, like Figure 3 and Figure 4 As shown, the base unit includes a base 1 and a rectangular enclosure 2 surrounding the top surface of the base 1 with an open top. The base 1 is a rectangular box shape with a base plate inside, on which the Arduino control board 4 and battery 32 are fixed. Rectangular holes 34 are provided on the stepped surface 3 formed by the edges of the base 1 and the rectangular enclosure 2 for mounting buttons and circuit wiring. The rectangular enclosure 2 covers the lower end of the drive unit, partially encapsulating it and providing both aesthetics and protection. Decorative words such as "flying colorful deer" can be engraved on the side panels of the rectangular enclosure 2.

[0041] Furthermore, an LED light can be installed on the upper surface of the base 1 inside the rectangular enclosure 2. This LED light is connected to the control board 4 and provides a dazzling lighting effect when the flying deer device is started.

[0042] This utility model's dynamic flying deer device boasts a highly realistic appearance and strong visual appeal; its movements are coordinated and natural, its structure is compact and highly interactive; its drive system is stable, and all components can be processed by laser cutting, making manufacturing and maintenance convenient. During use, the user turns on the power, the motor starts running, driving the linkage structure to periodically swing the deer's head, limbs, body, and tail, while LED lights flash, presenting a vivid mechanical interactive effect.
