Description

Technical Field

[0001] The utility model relates to the technical field of educational toys, in particular to an educational hand-cranked toy. Background Art

[0002] As society pays more and more attention to people with intellectual disabilities, more and more research and efforts are devoted to finding and innovating education, rehabilitation and entertainment methods suitable for this special group, especially in terms of brain exercise and cognitive improvement. Experts generally believe that through targeted stimulation and training, the brain development of people with intellectual disabilities can be effectively promoted, and their daily self-care ability and social skills can be improved.

[0003] Among numerous brain training methods, hand exercises are considered highly effective and easy to implement. They not only directly stimulate the corresponding areas of the cerebral cortex, promoting neuronal connectivity and functional improvement, but also improve hand-eye coordination, thereby enhancing cognitive function. For people with intellectual disabilities, hand exercises are particularly simple, engaging, and accessible. However, existing hand-cranked toys typically feature a single-handed design (such as traditional rattles), requiring only one-handed operation. These toys lack a mechanism for bimanual coordination, preventing simultaneous left and right brain stimulation and thus failing to meet the brain development needs of people with intellectual disabilities. Therefore, we propose an educational hand-cranked toy. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1:

[0030] See also Figure 1-7 The utility model provides a technical solution: an educational hand-cranked toy, comprising a shell 1, and a back plate is installed on the back side of the shell 1 through a snap fastener to facilitate the disassembly and assembly of internal parts. A transmission part 2 is assembled in the shell 1, and handles 3 are movably provided on both sides of the shell 1. The two handles 3 are both connected to the transmission part 2. When the user rotates one of the handles 3, under the action of the transmission part 2, the other set of handles 3 rotates synchronously in the opposite direction.

[0031] A shaft sleeve 4 is fixedly provided on both sides of the housing 1, and a rotating shaft 5 is rotatably provided inside the shaft sleeve 4. The two rotating shafts 5 can rotate synchronously in opposite directions through the transmission member 2, and the two handles 3 are fixedly connected to the rotating shafts 5 on both sides respectively.

[0032] The transmission member 2 includes an inner ring gear 24 fixedly arranged at the end of a rotating shaft 5, and a planetary gear set is movably arranged in the inner ring gear 24. The planetary gear set includes a planetary carrier 23 fixedly arranged at the end of a sleeve 4 outside the other rotating shaft 5. A plurality of planetary gears 22 meshing with the inner ring gear 24 are rotatably arranged on the planetary carrier 23, and a sun gear 21 meshing with the planetary gears 22 is fixedly arranged at the end of the other rotating shaft 5. A ring gear cover plate 25 is fixedly mounted on the side wall of the inner ring gear 24.

[0033] When the handle 3 connected to the sun gear 21 rotates, the sun gear 21 drives the planetary gear 22 to engage with it, and then drives the inner ring gear 24 to rotate in the opposite direction. The inner ring gear 24 drives the other handle 3 to rotate, which can realize the opposite rotation of the hands on both sides and the simultaneous opposite movement of the left and right hands, effectively exercising the left and right brains of the user, and promoting the user's brain development and cognitive improvement.

[0034] The gear ratio of the sun gear 21, the planetary gears 22 and the inner ring gear 24 is 1:2:5. In this embodiment, the number of teeth of the sun gear 21, the planetary gears 22 and the inner ring gear 24 are 12, 24 and 60 respectively. The gear ratio of 1:2:5 forms a simple integer relationship, which helps to achieve smooth engagement and reduce noise, thereby improving the user experience of the toy. In addition, the load distribution between the gears is relatively reasonable, which helps to reduce wear and extend the service life.

[0035] The number of planetary gears 22 is three. Based on the number of teeth of the sun gear 21, the planetary gears 22 and the inner ring gear 24, the number of planetary gears 22 is set to three. According to the relationship between the number of planetary gears 22 and the speed ratio, the speed ratio = the number of sun gear teeth + the number of planetary gear teeth / the number of sun gear teeth The number of planetary gears results in a speed ratio of 1:1, so that the rotation speeds of the two handles 3 are the same, which enables the two hands to move more coordinated and better exercise the left and right brains.

[0036] Example 2:

[0037] See also Figure 8-11 , different from the first embodiment, the second embodiment uses a different structure on the transmission member 2. The transmission member 2 includes a mounting shell 26 arranged between the two shaft sleeves 4. The two sides of the mounting shell 26 are fixedly connected to the shaft sleeves 4 on both sides. Two sets of bevel gears 1 27 are rotatably arranged in the mounting shell 26. The two sets of bevel gears 1 27 are concentrically arranged. The rotating shafts 5 on both sides are fixedly connected to the two sets of bevel gears 1 27. A bevel gear 28 is meshed between the two bevel gears 1 27. The bevel gear 2 28 is rotatably arranged on the inner wall of the mounting shell 26.

[0038] When the handle 3 on either side is rotated, it can drive the bevel gear 1 27 to rotate, and the bevel gear 1 27 engages with the bevel gear 2 28 to realize reverse transmission. When one handle 3 is rotated, it will drive the handle 3 on the other side to rotate in the opposite direction. In this way, the synchronous and coordinated movement of the two hands can be achieved, thereby effectively exercising the brain.

[0039] Embodiment 3;

[0040] On the basis of the first embodiment, a sleeve 6 is rotatably provided on the outer side of the handle 3 , and a plurality of notches are provided on the sleeve 6 , which conforms to the shape of the human hand and is easy to hold.

[0041] Example 4:

[0042] Based on the above embodiments, the housing 1 is provided with a simulated object 7, which is in the shape of a bird but is not limited thereto. It can also be in the shape of other small animals, aiming to attract users, enhance their interest in using the toy, and enable them to actively use the toy to achieve the effect of active exercise.

[0043] A vacuum suction cup 8 is fixedly mounted on the bottom of the housing 1 to securely mount the toy on a smooth surface for ease of use.

[0044] An ornament 9 is fixedly mounted on the top of the housing 1. The ornament 9 is a crown to increase the aesthetics.
