Description

Technical Field

[0001] This utility model relates to the field of toy steering technology, and more specifically, to a toy steering servo. Background Technology

[0002] A toy steering mechanism is a mechanical or electronic system used to control the direction of movement in a toy. Its design principles and structure vary depending on the type of toy. Its main functions include directional adjustment, improved maneuverability, and safety. Toy steering mechanisms achieve directional control through mechanical or electronic means, and their design must balance functionality, safety, and fun. Core technologies include linkage transmission, cushioning and weight reduction, angle limiting, and multi-mode control, while also meeting national stability standards to ensure children's safety.

[0003] For example, application number CN202222960146.3 discloses a controller for a high-precision toy car steering servo, which has the advantage of easy disassembly. This solves the problem that the controllers of existing rideable toy car steering servos cannot be disassembled, which may cause children to ride the toy car without parental supervision, resulting in unnecessary accidents and safety hazards. However, the existing toy steering servo structure is relatively complex and is prone to failure after long-term use, resulting in inflexible steering and affecting the normal use of the toy. After a period of use, the servo may exhibit a doubling phenomenon, that is, the actual rotation angle of the servo deviates from the angle required by the received signal, causing the toy's steering response to become insensitive and affecting the operating experience. Furthermore, the above-mentioned steering device is only used on toy cars and is not convenient to install on other toys that require steering, otherwise it will easily lead to a more complex steering servo structure, thus limiting the applicable environment of the above-mentioned device.

[0004] Therefore, a toy steering servo is proposed to address the above problems. Utility Model Content

The side end face of the first housing 1 is grooved, and a limiting groove is provided on the inner side of the first housing 1. The side of the second housing 2 facing the first housing 1 is grooved, and a limiting groove is provided on the inner side of the second housing 2. The limiting groove has the same shape as the drive motor 4. The drive motor 4 is located between the first housing 1 and the second housing 2. A through hole is provided on the side end face of the second housing 2, and the output end of the drive motor 4 extends through the through hole to one side of the second housing 2. A limiting hole is provided on the side end face of the second housing 2 away from the first housing 1. The third housing 3... A limiting hole is provided on the side end face of the housing 3 near the second housing 2. A third housing 3 is provided on the side of the second housing 2 away from the first housing 1. The side end face of the second housing 2 is fastened to the side end face of the third housing 3. A gear set 5 is provided between the second housing 2 and the third housing 3. The gear set 5 is limited and connected between the second housing 2 and the third housing 3 through the limiting hole. A positioning hole is carved through the side end face of the third housing 3. A drive gear 6 is provided at the output end of the gear set 5. The drive gear 6 is cylindrical, and a gear is provided at the edge of the outer surface of the drive gear 6. An arc-shaped limiting block 61 is provided on the outer surface of the gear. A first limiting groove 62 is carved on the side of the outer surface of the drive gear 6 away from the gear. The first limiting groove 62 is evenly distributed around the center of the drive gear 6. The gear set 5 is evenly arranged, and the drive gear 6, which is meshed with the gear group 5, extends through the positioning hole to one side of the third housing 3. The drive gear 6 is meshed with the steering rod 7. The device structure of this application is simple. After long-term use, this device can be maintained to prevent the steering from becoming inflexible, which would affect the normal use of the toy. In addition, the outer surface of the drive gear 6 in this device is equipped with an arc-shaped limiting block 61. The arc-shaped limiting block 61 is used to prevent the drive gear 6 from rotating excessively, which would cause the servo to have a play phenomenon. It also prevents the drive gear 6 from driving the steering rod 7 to rotate insensitively, which would affect the steering of the toy and avoid affecting the toy's operation experience. The steering rod 7 is long and narrow, and a connecting hole 71 is provided through the side end face of the steering rod 7. The inner diameter surface of the connecting hole 71 is carved with a second A limiting groove 72 is provided. A steering groove 73 is provided at the end of the steering rod 7 furthest from the connecting hole 71. The drive gear 6 is engaged with the second limiting groove 72 on the inner diameter surface of the connecting hole 71 on the side end face of the steering rod 7 via a first limiting groove 62 on its outer surface. When the drive motor 4 is started, the drive motor 4 drives the drive gear 6 to rotate using the gear set 5. The drive gear 6 is limited and connected to the steering rod 7 via the first limiting groove 62 and the second limiting groove 72, ultimately driving the steering rod 7 to rotate, achieving precise steering of the toy. This device is not only used on toy cars but also applicable to other steerable devices, thus increasing its applicability. In this embodiment, the drive motor 4 and other components are commercially available and known to those skilled in the art.Customization or model selection is available based on actual needs. Here, we are only using it and have not made any structural or functional improvements; therefore, we will not elaborate further.

[0027] The working process of this utility model is as follows: Start the drive motor 4, and the drive motor 4 drives the drive gear 6 to rotate through the gear set 5. The drive gear 6 is connected to the steering rod 7 through the first limiting groove 62 and the second limiting groove 72, thereby driving the steering rod 7 to rotate, so as to achieve the effect of precise steering of the toy. The structure of this application is simple. When this device is used for a long time, it is easy to maintain the device and avoid affecting the normal use of the toy. Moreover, the arc-shaped limiting block 61 installed on the outer surface of the drive gear 6 blocks the rotation of the drive gear 6, avoiding the phenomenon of dodging of the servo motor, which would make the response of the drive gear 6 to drive the steering rod 7 to rotate less sensitively, affecting the steering of the toy and the toy's operation experience.
