Description

Technical Field

[0001] This invention relates to the field of toy technology, and in particular to a hand-cranked remote control toy. Background Technology

[0002] Technological advancements have spurred the development of the children's toy industry. Today, a wide variety of children's toys, each with its own unique style and function, not only bring joy to children's lives but also play a significant role in their early intellectual development.

[0003] Remote-controlled toys, as a new generation of technological toys, are particularly popular. Existing remote-controlled toys typically include both remote controls and electric toys. Electric toys are primarily controlled by a joystick on the remote control; electric toy cars were the most prominent example of this type. However, most existing remote-controlled toys rely on the joystick's up, down, left, and right movements to control the electric toy's direction. This method of play is relatively simple, monotonous, and lacks fun and entertainment value. Summary of the Invention

[0004] Therefore, the purpose of this invention is to overcome the shortcomings of the prior art and provide a hand-cranked remote control toy. The toy is controlled by hand and has a novel way of playing, strong interactivity, and strong entertainment and fun.

[0035] This embodiment provides a hand-cranked remote control toy, including a remote control 100 and a toy body 200. The remote control 100 includes a handle housing 10, a hand crank 20, and a sensing and processing unit 30. The hand crank 20 is rotatably mounted on the handle housing 10. The sensing and processing unit 30 is disposed in the handle housing 10 and is used to sense the rotation speed signal of the hand crank 20 and convert the rotation speed signal into a drive signal to control the operation of the toy body 200. The toy body 200 includes a main body 40, a receiving and driving unit 50 disposed in the main body 40, a speed-changing driving mechanism 60, and a walking mechanism 70 designed on both sides of the main body 40. The receiving and driving unit 50 is used to receive the drive signal and drive the speed-changing driving mechanism 60 to work according to the drive signal. The speed-changing driving mechanism 60 is connected to the walking mechanism 70 in a transmission manner.

[0036] Specifically, the transmission drive mechanism 60 includes a drive mounting base 61, a drive motor 62 mounted on the drive mounting base 61, a drive gear 63 mounted on the output end of the drive motor 62, a clutch gear 64 meshing with the drive gear 63, an acceleration gear 65, a reduction gear 66, and an output gear 67. The receiving drive unit 50 is drivenly connected to the drive motor 62. The clutch gear 64 is slidably mounted on the drive mounting base 61. The acceleration gear 65 and the reduction gear 66 are respectively meshed with the output gear 67. The output gear 67 is drivenly connected to the walking mechanism 70. The receiving drive unit 50 is used to receive the drive signal and drive the drive motor 62 to rotate forward or backward according to the received drive signal, thereby driving the clutch gear 64 to mesh with the acceleration gear 65 or the reduction gear 66.

[0037] Optionally, a plurality of transmission gears 68 may be provided between the drive gear 63 and the clutch gear 64 as intermediate connecting gears, thereby facilitating the installation of the drive motor 62 and the clutch gear 63.

[0038] Optionally, the hand crank 20 includes a hand crank shaft 21 rotatably mounted on the handle housing 10, and handles 22 and a turntable 23 disposed at both ends of the hand crank shaft 21; the handles 22 are located on the outside of the handle housing 10, the turntable 23 is located on the inside of the handle housing 10, and the turntable 23 is disposed opposite to the sensing processing unit 30; a magnet unit 24 is provided on the side of the turntable 23 opposite to the sensing processing unit 30, and the sensing processing unit 30 is provided with a magnetic induction sensor 31 for detecting the rotational speed of the magnet unit 24;

[0039] When the handle 22 drives the turntable 23 to rotate, the magnet unit 24 on the turntable 23 is simultaneously driven to rotate. The magnetic induction sensor 31 is used to sense the rotation speed signal of the magnet unit 24 and transmits the rotation speed signal to the induction processing unit 30, which processes it into a drive signal to control the operation of the toy body 200. The magnetic induction sensor 31 is a Hall sensor.

[0040] Optionally, the reduction gear 66 includes a first gear and a second gear rigidly connected coaxially, the outer diameter of the first gear being larger than the outer diameter of the second gear, and the second gear meshing with the output gear 67; the acceleration gear 65 is a single-layer gear structure, and a plurality of meshing transmission gears are provided between the clutch gear 64 and the drive gear 63; when the drive motor 62 rotates in the forward direction, the clutch gear 64 slides to the reduction gear 66 and meshes with the first gear of the reduction gear 66; when the drive motor 62 rotates in the reverse direction, the clutch gear 64 slides to the acceleration gear 65 and meshes with the acceleration gear 65.

[0041] Therefore, in this embodiment, the hand-cranked remote control toy can rotate the turntable 23 by holding the handle housing 10 with one hand and the hand crank 20 with the other. The magnetic induction sensor 31 senses the rotation speed signal of the magnet unit 24 on the turntable 23 and sends the sensed rotation speed signal to the induction processing unit 30. After conversion and processing by the induction processing unit 30, a corresponding drive signal is sent to the receiving drive unit 50 in the toy body 200. After receiving the drive signal, the receiving drive unit 50 drives the drive motor 62 to rotate.

[0042] Furthermore, the rotation speed of the hand crank 20 in this embodiment can be divided into three speed signals: low, medium, and high. The low, medium, and high speed thresholds are set in the sensing processing unit 30.

[0043] When the hand crank 20 rotates at low speed, the magnetic induction sensor 31 sends the detected speed signal to the induction processing unit 30. After conversion by the induction processing unit 30 and comparison with the speed thresholds of the low, medium and high gears, it sends a drive signal to the receiving drive unit 50 to drive the motor 62 to rotate in the forward direction. After receiving the drive signal, the receiving drive unit 50 can drive the drive motor 62 to rotate in the forward direction. At this time, the drive gear 63 at the output end of the drive motor 62 rotates in the forward direction and drives the clutch gear 64 to slide to the reduction gear 66 and mesh with the first gear of the reduction gear 66. Then, the reduction gear 66 drives the output gear 67 to rotate at low speed, so that the walking mechanism 70 walks at a low speed.

[0044] Similarly, when the hand crank 20 rotates at a medium speed, the magnetic induction sensor 31 sends the detected rotation speed signal to the induction processing unit 30. The induction processing unit 30 converts the signal and compares it with the rotation speed thresholds for low, medium, and high speeds, then sends a drive signal to the receiving drive unit 50 to reverse the rotation of the drive motor 62. Upon receiving this drive signal, the receiving drive unit 50 drives the drive motor 62 to rotate in the opposite direction. At this time, the drive gear 63 at the output end of the drive motor 62 rotates in the opposite direction, causing the clutch gear 64 to slide to and mesh with the acceleration gear 65. The acceleration gear 65 then drives the output gear 67 to rotate at a medium speed, ultimately resulting in a medium-speed walking mechanism 70. If the rotation speed of the hand crank 20 is further increased until the rotation speed signal received by the induction processing unit 30 exceeds the high-speed threshold, the induction processing unit 30 will send a high-frequency reverse rotation drive signal to the drive motor 62. This, in turn, drives the drive motor 62 to rotate in the opposite direction at a high frequency through the receiving drive unit 50, ultimately resulting in a high-speed walking mechanism 70.

[0045] In order to increase the rhythm of the remote control 100, the turntable 23 in this embodiment is a rotating gear. A long strip plate 14 is provided inside the handle housing 10. The end of the long strip plate 14 is located on the outer teeth of the rotating gear. In this way, when the rotating gear rotates, the outer teeth of the rotating gear will continuously touch and push open the long strip plate 14, thereby producing a "da da da" musical effect. The user can also feel the collision rhythm between the rotating gear and the long strip plate 14 through the handle 22 of the hand crank 20.

[0046] Optionally, an indicator light 11 may also be provided on the handle housing 10, and a remote control power supply 12 and a remote control switch 13 are provided inside the handle housing 10. In this way, the remote control power supply 12, the remote control switch 13, the sensing processing unit 30 and the indicator light 11 are electrically connected. When the remote control switch 13 is turned on, the indicator light 11 is lit.

[0047] In addition, the output gear 67 in this embodiment is coaxially rigidly connected to an output shaft. The two ends of the output shaft extend out of the two sides of the drive mounting base 61 and are coaxially rigidly connected to eccentric wheels 671. Eccentric shafts 672 are respectively provided on the outer circumference of the two eccentric wheels 671. Linkage rods 80 are respectively provided on the two inner sides of the main body 40. The two linkage rods 80 are respectively provided with linkage grooves 81 that match the eccentric shafts 672 of the two eccentric wheels 671, and the two eccentric shafts 672 are respectively set on the linkage grooves 81 of the two linkage rods 80.

[0048] Furthermore, the two linkage rods 80 are respectively provided with a plurality of sliding grooves 83, and the two sides of the main body 40 are respectively provided with a plurality of fixed posts 44 that match the plurality of sliding grooves 83, and each sliding groove 83 is respectively set on the corresponding fixed post 44; the drive motor 62 drives the output gear 67 to rotate, and through the eccentric wheels 671 at both ends of the output gear 67, drives the plurality of sliding grooves 83 of the two linkage rods 80 to slide on the plurality of fixed posts 44 on both sides of the main body 40.

[0049] Optionally, the main body 40 has bearing holes 41 on both sides and drive grooves 42 and arc-shaped grooves 43 on both sides of the bearing holes 41. The outer sides of the two linkage rods 80 are provided with drive shafts 82, and the two drive shafts 82 are slidably disposed in the drive grooves 42 on both sides of the main body 40. The two walking mechanisms 70 have rotating shafts 71 on the side opposite to the main body 40 and insertion holes 72 and sliding columns 73 on both sides of the rotating shafts 71. The two walking mechanisms 70 are rotatably sleeved in the bearing holes 41 on both sides of the main body 40 through the rotating shafts 71. The drive shafts 82 of the two linkage rods 80 are inserted into the insertion holes 72 of the two walking mechanisms 70, and the sliding columns 73 of the two walking mechanisms 70 are slidably disposed in the arc-shaped grooves 43 on both sides of the main body 40.

[0050] Therefore, when the eccentric wheels 671 at both ends of the output gear 67 drive the two linkage rods 80 to slide back and forth on the main body 40, the drive shafts 82 of the two linkage rods 80 are inserted into the two insertion holes 72 of the two walking mechanisms 70. In this way, the two walking mechanisms 70 use their rotating shafts 71 as the pivot point and slide in the arc groove 43 of the main body 40 through the sliding column 73 under the drive of the two linkage rods 80, thereby realizing the dynamic effect of the two walking mechanisms 70 swinging.

[0051] Furthermore, the bottom of each of the two traveling mechanisms 70 is provided with a plurality of gears 74, and the bottom of each of the two traveling mechanisms 70 is provided with a groove that can accommodate the rotation of the plurality of gears 74. The two ends of the shaft of each gear 74 are slidably disposed on both sides of the corresponding groove, and the front end of the groove is provided with a ratchet rack 75. When the gear 74 rotates clockwise forward, the end of the gear 74 away from the ratchet rack 75 slides and separates the gear 74 from the ratchet rack 75. When the gear 74 rotates counterclockwise backward, the end of the gear 74 close to the ratchet rack 75 slides and the ratchet rack 75 locks the gear 74.

[0052] Therefore, when one of the traveling mechanisms 70 swings forward, the gears 74 on the forward-swinging traveling mechanism 70 rotate clockwise forward. The end of the gear 74 away from the ratchet 75 slides, causing the gear 74 to separate from the ratchet 75, thus causing the gears 74 of the forward-swinging traveling mechanism 70 to rotate forward. At the same time, the other traveling mechanism 70 swings backward, and the gears 74 on the backward-swinging traveling mechanism 70 rotate counterclockwise backward. The end of the gear 74 close to the ratchet 75 slides, causing the ratchet 75 to engage the gear 74, thus keeping the gears 74 of the backward-swinging traveling mechanism 70 locked in place. Furthermore, under the reciprocating action of the two linkages 80, the two traveling mechanisms 70 swing forward alternately, obtaining forward movement power through the gears 74 of the forward-swinging traveling mechanism 70.

[0053] Furthermore, with this structural design, regardless of whether the drive motor 62 rotates forward or backward, as long as the two walking mechanisms 70 swing back and forth, they can maintain a forward movement direction through the gears 74 at the bottom of the two walking mechanisms 70, without any backward movement. Optionally, in this embodiment, the front end of the bottom of the two walking mechanisms 70 is provided with two parallel gears 74, and the rear end is provided with one gear 74.

[0054] Optionally, the front end of the main body 40 is provided with a head 45, the head 45 including an upper housing and a lower housing rotatably disposed in the upper housing; the output gear 67 is meshed with a head eccentric wheel 69, and an eccentric rod 691 is provided on one side circumferential surface of the head eccentric wheel 69; the main body 40 is provided with a linkage plate 90, the linkage plate 90 is provided with a transverse groove 91 and longitudinal grooves 92 spaced apart on the upper and lower sides of the transverse groove 91, the eccentric rod 691 is sleeved on the transverse groove 91, and guide posts are respectively provided on the two longitudinal grooves 92, the head When the eccentric wheel 69 rotates, it drives the eccentric rod 691 to slide in the transverse groove 91, causing the linkage plate 90 to move up and down along the guide post of the longitudinal groove 92. The top of the linkage plate 90 is provided with a sliding groove 93. The upper housing is rotatably provided with a linkage disc 94. The outer end of the linkage disc 94 is set in the sliding groove 93 through a drive rod, and a drive plate 95 is connected to the drive rod. The other end of the drive plate 95 abuts against the lower housing. The linkage plate 90 drives the drive rod to rotate through the sliding groove 93, thereby driving the drive plate 95 to press down and causing the lower housing to rotate upward.

[0055] In addition, the main body 40 is provided with hands 46 on both sides, and the two hands 46 are rotatably mounted on the main body 40. One side of each hand 46 extends into the interior of the main body 40 and is fixedly connected to the two linkage rods 80. The rear end of the main body 40 is rotatably provided with a tail 47, and one end of each linkage rod 80 abuts against the front side of the tail 47.

[0056] Optionally, in this embodiment, the toy body 200 imitates the shape of a dinosaur. The main body 40 is the dinosaur's torso, and the two walking mechanisms 70 are the dinosaur's lower legs. Thus, when the two linkage rods 80 move forward and backward respectively, the two hands 46 also rotate forward and backward accordingly. At the same time, the tail 47 can also achieve a dynamic effect of swaying left and right. In this way, the simulated electric toy of this embodiment can vividly imitate the dinosaur's walking, mouth opening and closing, hand 46 rotation, and tail wagging actions. The simulation effect is very realistic, and it has rich dynamic effects, which greatly increases the toy's entertainment and fun.

[0057] The toy body 200 further includes a driving power supply 48, a driving switch 49, a lighting component, and a music component. The driving power supply 48 and the driving switch 49 are electrically connected to the lighting component, the music component, the receiving driving unit, and the driving motor 62, respectively. In this embodiment, the driving power supply 48 is located inside the bottom of the walking mechanism 70, which increases the weight of the walking mechanism 70, thereby lowering its center of gravity during walking. The lighting component includes several LED beads, which can be respectively located in the head 45 or other parts. The music component includes a music board and a speaker. The speaker is located at the bottom of the main body 40 and is driven by the music board to produce sound.

[0058] Compared with existing technologies, the hand-cranked remote control toy of the present invention uses a hand crank 20 to drive and control the toy body 200. Specifically, the sensing processing unit 30 senses the rotation speed signal of the hand crank 20 and converts it into a drive signal for controlling the operation of the toy body 200. Furthermore, the sensing processing unit 30 can output different drive signals according to the rotation speed of the hand crank 20. Combined with the speed-changing drive mechanism 60 on the toy body 200, this enables the toy body 200 to have different operating modes, achieving a strong interactive effect. The design is ingenious, the gameplay is novel, and it has strong entertainment and fun. Further, the present invention uses a drive motor 62 to move two linkage rods 80, which in turn drives the walking mechanism 70 to swing. The walking mechanism 70 moves forward with the rotation of the gear 74 at the bottom. Simultaneously, the two linkage rods 80 drive the head 45, hands 46, and tail 47 to move, thereby achieving a dynamic effect that imitates animal walking, greatly enhancing the toy's realism and entertainment value.

[0059] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the hand-cranked remote-controlled toy.
