Description

Technical Field

[0001] This utility model relates to the field of toy technology, specifically a gear transmission control device and a gear toy thereof. Background Technology

[0002] Existing gear toys are diverse. For example, CN104941198B discloses a gear toy including a vehicle body and rotatable parts mounted on the vehicle body. The vehicle body has a wheel system, which includes multiple wheel sets and wheel axles. Multiple axle holes are provided on the vehicle body for the wheel axles to pass through. Multiple connecting protrusions are provided on the upper surface of the vehicle body. The rotatable parts include a bracket and a gear and a worm gear mounted within the bracket. The bottom of the bracket has a connecting groove. The gear is connected to the bracket via an output shaft, and the worm gear is connected to the bracket via an input shaft. The input shaft is connected to a drive gear, which meshes with one of the wheels in the wheel set. The gear toy of this invention uses gear-shaped wheels and uses auxiliary wheels to drive the wheels in a linkage manner between multiple wheels on the same side. The transmission components of the rotatable parts on the vehicle body mesh with the wheels for linkage driving. However, this technical solution does not disclose how to control the rotation of the gears.

[0003] For example, CN205796519U discloses a gear-shaped toy car, including a car body, a drive motor, and gears mounted on the car body for driving the car's movement and display. The gears include a wheel and multiple toothed pieces. Multiple openings are evenly distributed along the circumference of the wheel's edge, and each toothed piece corresponds to one of the openings. All toothed pieces are movably connected to the wheel. A drive assembly is also provided on the wheel to drive the toothed pieces to move radially or axially along the wheel. This technical solution controls the gear rotation by rotating a push rod. Since the push rod is threadedly connected to the connecting rod, the push rod drives the toothed pieces forward during its advancement, thereby pushing the toothed pieces to move axially along the wheel. Simultaneously, rotating the push rod, because its surface is hinged to the connecting rod, causes a change in the distance between the end of the connecting rod furthest from the push rod and the push rod itself, thus pushing the toothed pieces to move radially along the wheel.

[0004] However, since educational toys are developed to develop children's thinking skills in multiple ways, there is still a strong market demand for new designs and ways to play with various toys. Utility Model Content

[0005] The present invention aims to provide a new design solution for a gear toy.

[0006] The technical solution of this utility model is as follows:

The rotating protrusion is fixedly connected to the first switch, and rotating the first switch can drive the rotating protrusion to rotate. The return spring, the movable gear, and the movable mating block are sequentially sleeved on the fixed shaft. The movable gear is used to mesh with the driving gear and the driven gear to realize the transmission of the driving gear, the movable gear, and the driven gear. Rotating the first switch causes the rotating protrusion to hold the movable mating block and move it backward, which will drive the movable gear to move backward. At this time, the movable gear is disengaged from the driving gear and the driven gear. Rotating the first switch causes the rotating protrusion to be displaced from the movable mating block, the movable mating block is disengaged from the held state and reset under the action of the return spring. At this time, the movable gear meshes with the driving gear and the driven gear.

[0008] The movable mating block has a slot on the side opposite to the rotating protrusion.

[0010] The gear transmission control device also includes several external gears, which mesh with the driven gear.

[0011] The external gear meshes with the driven gear through other intermediate gears.

[0012] The gear transmission control device also includes a second switch, which is connected to one of the external gears and can control the rotation of the external gear.

[0013] The second switch is a manual switch.

[0014] The manual switch is shaped like a steering wheel or a handle.

[0015] This utility model also claims a gear toy that includes the aforementioned gear transmission control device, the toy comprising a housing, the housing comprising an outer shell and a bottom shell, the first switch and the external gear being mounted on the outer shell, and the fixed shaft being fixed on the bottom shell.

Detailed Implementation

[0029] To make the technical solution and beneficial effects of this utility model more obvious and easier to understand, the technical solution in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0030] like Figures 1-4As shown, a gear transmission control device includes a first switch 101, a rotating protrusion 102, a movable mating block 103, a movable gear 104, a fixed shaft 105, a return spring 110, a drive motor 108, a first external gear 201, a second external gear 301, and a third external gear 302. The first switch 101 and the fixed shaft 105 are respectively fixed to the housing. The rotating protrusion 102 is fixedly connected to the first switch 101. Rotating the first switch 101 can drive the rotating protrusion 102 to rotate. The return spring 110, the movable gear 104, and the movable mating block 103 are sequentially sleeved on the fixed shaft 105. The movable gear 104 is used to mesh with the driving gear 106 and the driven gear 109 to realize the transmission of the driving gear 106, the movable gear 104, and the driven gear 109. The driving gear 106 is connected to the output shaft 107 of the drive motor 108. The first external gear 201 meshes with the driven gear 109 through an intermediate gear. The second external gear 301 and the third external gear 302 mesh with the first external gear 201, respectively. The movable mating block 103 has a slot on the side opposite to the rotating protrusion 102. The gear transmission control device also includes a second switch 202, which is connected to the first external gear 201 and can control the rotation of the external gear. The second switch 202 is shaped like a steering wheel.

[0031] like Figures 5-6 As shown, a gear toy incorporating the aforementioned gear transmission control device includes a housing comprising an outer shell 401 and a bottom shell 402. A first switch 101 and three external gears are mounted on the outer shell 401, and a fixed shaft 105 is fixed to the bottom shell 402. The first switch 101 is mounted on the outer shell 401 via a mounting slot 4011. The housing has several slots for inserting other gear components, which are inserted into the housing and mesh with the first external gear 201.

[0032] The first way to use this invention is as follows: A battery is inserted, which powers the drive motor 108. The drive motor 108 drives the driving gear 106 to rotate, which in turn drives the moving gear 104 to rotate. The moving gear 104 then drives the driven gear 109 to rotate, and the driven gear 109 drives the first external gear 201 to rotate, thus achieving rotation of all external gears. Rotating the first switch 101 causes the rotating protrusion 102 to push against the moving engagement block 103 and move it backward, causing the moving gear 104 to move backward. At this time, the moving gear 104 disengages from the driving gear 106 and the driven gear 109. Even though the drive motor 108 is still working, the external gears have stopped rotating. Next, rotating the first switch 101 causes the rotating protrusion 102 to disengage from the moving engagement block 103. The moving engagement block 103 disengages from its pushed-against state and resets under the action of the return spring 110. At this time, the moving gear 104 re-engages with the driving gear 106 and the driven gear 109, and all external gears rotate again. Children can freely control the rotation or stationary position of the external gear by turning the first switch 101.

[0033] The second way to play with this utility model is as follows: No batteries are required. At this time, the child only needs to rotate the second switch 202 by hand to make all the external gears rotate; when the second switch 202 is stopped, the external gears will be stationary.
