Description

Technical Field

[0001] The utility model relates to the field of toy cars, in particular to a steering clutch device for a toy car. Background Art

[0002] With the improvement of living standards, remote control toy cars have become popular in ordinary families. Since the users of remote control toy cars are children, the functional consistency and durability of remote control toy cars are very important. At present, the front steering structure of a general remote control toy car is composed of a motor, a flapper fixing part, left / right flappers, a clutch gear, a gear train, a swing gear, an upper gearbox cover, a lower gearbox cover, a return spring, etc. The flapper fixing part is pressed on the rotating shaft of the front steering motor. There is a convex handle on each side of the flapper fixing part. The left / right flappers are sleeved on the convex handles of the flapper fixing part, and then a clutch gear is covered and transmitted to the gear train. The last stage is connected to the swing gear. When the drive system of the remote control car receives a left turn / right turn command, it controls the front steering motor to rotate. The motor flapper fixing part starts to rotate. With the high-speed rotation of the motor, the two left / right flappers sleeved on the flapper fixing part are affected by centrifugal force and are closely attached to the inner wall of the clutch gear, thereby driving the clutch gear to rotate. Through the transmission gear train, the power is finally transmitted to the swing gear to drive the front steering connecting rod to work, achieving the purpose of steering the remote control toy car. The defects of the above traditional remote control toy car are as follows: due to the large number of parts and complex processes, the assembly of the left / right flappers is very time-consuming, and multiple special assembly jigs need to be made, and the consistency of the product cannot be guaranteed, and the defective rate is relatively high in large-scale production. Content of the Utility Model

[0003] The purpose of the utility model is to solve the above technical problems, and to provide a steering clutch device for a toy car. This application aims to provide a steering clutch device for a toy car with an integrally formed flapper.

[0004] A steering clutch device for a toy car includes a gearbox, a motor, an integrally formed flapper gear, a clutch gear, and an output component. The integrally formed flapper gear, the clutch gear, and the output component are installed in the gearbox. The integrally formed flapper gear includes a central part and a flapper part. The flapper part extends outward from the central part. The central part is installed on the output shaft of the motor. One side of the clutch gear is provided with a friction groove. The integrally formed flapper gear extends into the friction groove. The clutch gear is in transmission connection with the output component. The integrally formed flapper gear rotates under the drive of the motor, so that the flapper part rubs against the inner wall of the friction groove and drives it to rotate.

[0005] The steering clutch device of the toy car according to the present application uses an integrally formed one-piece flapper tooth. Compared with the split flapper of the prior art, multiple assembly processes can be omitted, labor can be saved, production can be increased, and it is strong and durable. When steering, the flapper part presses against the inner wall of the friction groove under the action of centrifugal force to generate frictional force to drive the clutch gear to rotate. After the steering is in place, the positions of the clutch gear and the output assembly are fixed. Since the one-piece flapper tooth does not engage with the clutch gear in a gear manner, the one-piece flapper tooth can rotate continuously inside the clutch gear, the motor will not be blocked, and a frictional force will be generated to maintain the steering state through the frictional force all the time.

[0006] Further, two flapper parts are symmetrically provided on the one-piece flapper tooth. The symmetrically arranged flappers can make the frictional force more uniform and make the steering action of the toy car smoother.

[0007] Still further, the flapper part extends in a tadpole-shaped arc. The head of the tadpole-shaped flapper part is larger, which is convenient for generating frictional force by rubbing against the inner wall of the friction groove. The tail is connected to the central part, and the size of the tail is smaller, which is convenient for elastic deformation so that the flapper part can rub against the inner wall of the friction groove under the action of centrifugal force.

[0008] Still further, the output assembly includes a gear train and a swing tooth. The gear train meshes with the clutch gear, and one end of the swing tooth meshes with the gear train, and the other end extends out of the gearbox with a swing rod. By swinging the swing rod left and right, the toy car can turn left and right.

[0009] Still further, a swing limit groove is provided on the gearbox, and the swing rod extends out of the gearbox through the swing limit groove. The swing limit groove can limit the swing angle of the swing rod.

[0010] Still further, it further includes a steering rod. The swing rod is inserted into the steering rod to drive the steering rod to swing and turn. By driving the wheels of the toy car to turn through the steering rod, when the swing rod is inserted into the steering rod, the left and right swing of the swing rod can drive the steering rod to turn left and right.

[0011] Still further, it further includes a return spring, and the return spring resets the steering rod. When the motor does not output power, the return spring drives the entire steering clutch device to reset.

[0012] Still further, the flapper part is separated from the inner wall of the friction groove when the motor does not drive the one-piece flapper tooth to rotate. This avoids the one-piece flapper tooth from hindering the return spring from resetting. Description of the Drawings

[0019] A steering clutch device of a toy car according to the present utility model will be described with reference to the accompanying drawings.

[0020] As Figures 1 to 6 shown, a steering clutch device of a toy car includes a gearbox 1, a motor 2, an integral flapper gear 3, a clutch gear 4, and an output assembly 5. The integral flapper gear 3, the clutch gear 4, and the output assembly 5 are installed in the gearbox 1. The gearbox 1 is divided into upper and lower parts and is fixedly connected by screws to form the gearbox 1, which can facilitate the installation of the integral flapper gear 3, the clutch gear 4, and the output assembly 5 into the gearbox 1. The integral flapper gear 3 includes a central portion 31 and a flapper portion 32. The flapper portion 32 extends outward from the central portion 31. The central portion 31 is installed on the output shaft of the motor 2. The integral flapper gear 3 made by an integral molding process can save multiple assembly processes compared with the prior art split flapper, save labor, increase production, and is strong and durable. One side of the clutch gear 4 is provided with a friction groove 41. The integral flapper gear 3 extends into the friction groove 41. The clutch gear 4 is in transmission connection with the output assembly 5. The integral flapper gear 3 rotates under the drive of the motor 2, so that the flapper portion 32 rubs against the inner wall of the friction groove 41 and drives it to rotate. When steering, the flapper portion 32 presses against the inner wall of the friction groove 41 under the action of centrifugal force to generate a frictional force to drive the clutch gear 4 to rotate. After the steering is in place, the positions of the clutch gear 4 and the output assembly 5 are fixed. Since the integral flapper gear 3 does not engage with the clutch gear 4 by gears, the integral flapper gear 3 can rotate continuously inside the inner wall of the clutch gear 4, and the motor 2 will not be blocked, and moreover, a frictional force will be generated to maintain the steering state through the frictional force all the time.

[0021] As Figure 3 and Figure 4 shown, the integral flapper gear 3 is symmetrically provided with two flapper portions 32. The symmetrically arranged flappers can make the frictional force more uniform and make the steering action of the toy car smoother.

[0022] AsFigure 3 and Figure 4 As shown, the flinging part 32 extends in a tadpole-shaped arc. The head of the tadpole-shaped flinging part 32 is larger, facilitating friction with the inner wall of the friction groove 41 to generate frictional force. The tail is connected to the central part 31, and the size of the tail is smaller, facilitating elastic deformation, enabling the flinging part 32 to friction with the inner wall of the friction groove 41 under the action of centrifugal force.

[0023] As Figures 1 to 6 shown, the output assembly 5 includes a gear train 51, a swing tooth 52, and a rotating shaft 53. The rotating shaft 53 is fixed in the gearbox 1. The gear train 51 is rotatably installed on the rotating shaft 53. The gear train 51 meshes with the clutch tooth 4. One end of the swing tooth 52 meshes with the gear train 51, and the other end extends out of the gearbox 1 with a swing rod 521. By swinging the swing rod 521 left and right, the toy car can turn left and right. It also includes a steering rod 6. Both ends of the steering rod 6 are connected to two wheels. By swinging left and right, the two wheels can be driven to rotate in different directions, enabling the toy car to turn. The swing rod 521 is inserted into the steering rod 6 to drive the steering rod 6 to swing and turn. By driving the wheels of the toy car to turn through the steering rod 6, when the swing rod 521 is inserted into the steering rod 6, the steering rod 6 can be driven to turn left and right by swinging the swing rod 521 left and right.

[0024] As Figures 1 to 2 shown, it further includes a return spring 7. The return spring 7 returns the steering rod 6. When the motor 2 does not output power, the return spring 7 drives the entire steering clutch device to return.

[0025] The flinging part 32 is separately arranged from the inner wall of the friction groove 41 when the motor 2 does not drive the integral flinging tooth 3 to rotate, avoiding the integral flinging tooth 3 from hindering the return of the return spring 7.

[0026] A swing limit groove is provided on the gearbox 1. The swing rod 521 extends out of the gearbox 1 from the swing limit groove. The swing limit groove can limit the swing angle of the swing rod 521, preventing the swing rod 521 from swinging excessively and disengaging from the steering rod 6.
