Description

Technical Field

[0001] This utility model relates to the field of toy technology, specifically to a drifting toy car. Background Technology

[0002] Currently, there are all kinds of toy cars on the market. Existing toy cars, with their vivid shapes and versatile functions, are occupying more and more of the consumer market and are becoming increasingly popular with children.

[0003] Existing toy cars can generally perform actions such as moving forward, backward, turning, and stopping. However, due to their relatively simple drive mechanisms, these toy cars cannot drift or glide, resulting in poor playability and fun, and easily leading to boredom. Furthermore, although there are toy cars that can drift via remote control, their drifting mechanisms are complex, and most are electrically controlled, making them expensive and somewhat difficult for the operator. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a drifting toy car that can automatically drift during operation, has high fidelity and simulation, and features a simple structure and low production cost. The technical solution adopted is as follows:

[0005] A drifting toy car includes a frame, a driving mechanism, two front wheels, and two rear wheels. The two front wheels are rotatably mounted on the left and right sides of the front of the frame, and the two rear wheels are rotatably mounted on the left and right sides of the rear of the frame. The drifting toy car further includes a drifting mechanism, which includes a support body, wheel axles, a movable frame, a steering shaft, a steering wheel, a camshaft, a cam, and a swing arm. The support body is mounted on the frame, and the wheel axles are rotatably mounted on the support body and run left-right. The wheel axles are connected to the output end of the driving mechanism. The two front wheels or the two rear wheels are respectively mounted on the left and right ends of the wheel axles. The left or right end of the movable frame is hinged to the support body. The steering shaft is rotatably mounted on the movable frame and runs in a front-to-back direction. The steering shaft and the wheel axle are connected by a first transmission mechanism. The steering wheel is fixedly mounted on the steering shaft and is located between the two front wheels and the two rear wheels. The camshaft is rotatably mounted on the support body and runs in a vertical direction. The camshaft and the wheel axle are connected by a second transmission mechanism. The cam is fixedly mounted on the camshaft. The swing arm is located between the cam and the movable frame. The middle part of the swing arm is hinged to the support body through a vertically running connecting shaft. The rear end of the swing arm contacts the wheel surface of the cam, and the front end of the swing arm contacts the right or left end of the movable frame.

[0006] In use, the wheel axle rotates continuously under the drive of the driving mechanism, causing the two rear wheels or two front wheels on it to rotate, making the drifting toy car move forward or backward. During the movement, the rotating wheel axle drives the steering shaft and steering wheel to rotate continuously through the first transmission mechanism. At the same time, the wheel axle drives the cam shaft and cam to rotate continuously through the second transmission mechanism. By utilizing the cooperation between the cam's wheel surface and the rear end of the swing arm, the front end of the swing arm swings back and forth around the connecting shaft, causing the movable frame and steering wheel to swing up or down around the hinge point with the support body, so that the steering wheel contacts or disengages from the vehicle's driving surface (the contact between the steering wheel and the vehicle's driving surface can be controlled by the design of the cam's wheel surface). The contact and separation times of the drifting toy car are adjusted to change its driving state: when the steering wheel swings downward under the action of the movable frame until it contacts the driving surface, the rotating steering wheel changes the driving direction of the drifting toy car, allowing it to automatically drift during driving; when the steering wheel swings upward under the action of the movable frame until it separates from the driving surface, the drifting toy car is in normal driving state. This allows the drifting toy car to automatically drift at intervals during driving, with high fidelity and simulation, increasing its playability and fun. Compared with existing remote-controlled drifting toy cars, it has a simple structure and low production cost.

[0007] As a specific embodiment of this utility model, the rear end of the swing arm is provided with a wedge-shaped part, which contacts and engages with the wheel surface of the cam.

[0008] In a preferred embodiment of this invention, the left end of the movable frame is hinged to the support body, and the right end of the movable frame is provided with a first guide slope that gradually slopes upward from left to right. The front end of the swing arm is provided with a second guide slope that gradually slopes upward from left to right. The second guide slope is located below the first guide slope and contacts and engages with it. When the front end of the swing arm swings to the left about the connecting axis, the engagement between the second guide slope of the swing arm and the first guide slope of the movable frame can be used to push the movable frame to swing upward about its left hinge point, causing the steering wheel to disengage from the vehicle's travel surface.

[0009] In another preferred embodiment of this utility model, the right end of the movable frame is hinged to the support body. The right end of the movable frame is provided with a first guide slope that gradually slopes downward from left to right, and the front end of the swing arm is provided with a second guide slope that gradually slopes downward from left to right. The second guide slope is located below the first guide slope and contacts and engages with the first guide slope. When the front end of the swing arm swings to the right about the connecting axis, the engagement between the second guide slope of the swing arm and the first guide slope of the movable frame can be used to push the movable frame to swing upward about its right end hinge, causing the steering wheel to disengage from the vehicle's travel surface.

[0010] As a preferred embodiment of this utility model, the support body is a shell with an inner cavity, and the movable frame, swing arm, cam, first transmission mechanism, and second transmission mechanism are all disposed in the inner cavity of the shell; the bottom plate of the shell has a mounting opening, and the lower part of the steering wheel extends from the mounting opening to the lower side of the shell. The shell is used to protect the various components of the drifting mechanism and also makes the drifting toy car more aesthetically pleasing.

[0011] To ensure the movable frame maintains contact with the front end of the swing arm, as a further preferred embodiment of this invention, the drifting mechanism further includes a return spring. The return spring is disposed within the inner cavity of the housing and between the top plate of the housing and the movable frame. The upper and lower ends of the return spring are connected to the top plate of the housing and the movable frame, respectively. This allows the movable frame to tend to move upwards under the action of the return spring, enabling it to closely contact the front end of the swing arm.

[0012] As a further preferred embodiment of this utility model, an opening is provided on one side of the housing, and an operating part is provided at the front end of the swing arm, protruding from the opening to the outside of the housing. The player can manually press the operating part to push the movable frame and the steering wheel upward around the hinge point between them and the support body, so that the steering wheel disengages from the vehicle's driving surface.

[0013] In a preferred embodiment of this invention, the first transmission mechanism includes a drive gear, a drive shaft, an end face gear, a first transmission gear, and a second transmission gear. The drive gear is fixedly mounted on the wheel axle. The drive shaft is rotatably mounted on the support body and runs in a front-to-back direction. The end face gear is fixedly mounted on the rear end of the drive shaft and meshes with the drive gear. The first transmission gear is fixedly mounted on the front end of the drive shaft. The second transmission gear is fixedly mounted on the steering shaft and meshes with the first transmission gear. When the drifting toy car is in motion, the drive gear rotates under the drive of the wheel axle, which then drives the drive shaft and the first transmission gear to rotate via the end face gear, and finally drives the steering shaft and the steering wheel to rotate via the second transmission gear.

[0014] As a preferred embodiment of this invention, the second transmission mechanism includes a worm and a worm wheel. The worm is fixedly mounted on the wheel axle, and the worm wheel is fixedly mounted on the camshaft and meshes with the worm. With this structure, the worm rotates under the drive of the wheel axle, and then drives the camshaft and cam to rotate via the worm wheel. This allows for a large reduction ratio between the wheel axle and the camshaft, enabling the cam to rotate at a slower speed for better control of the drifting toy car's movement. Alternatively, the second transmission mechanism can employ a reduction gear set with a large reduction ratio.

[0015] As a preferred embodiment of this utility model, the driving mechanism is an inertial gearbox, which is mounted on the vehicle frame or the support body, and the output shaft of the inertial gearbox is connected to the wheel axle for transmission. The inertial gearbox can be driven by inertia alone without the need for external power, reducing operating costs and improving ease of use and practicality.

[0016] The aforementioned driving mechanism can also employ an electric motor, with the output shaft of the electric motor connected to the wheel axle. In use, the electric motor drives the wheel axle to rotate, propelling the drifting toy car. The electric motor can also be remotely controlled via a remote control.

[0017] To protect the components on the frame and to make the drifting toy car more aesthetically pleasing, as a preferred embodiment of this invention, the drifting toy car also includes a car shell, which is mounted on the frame.

[0018] In this utility model, "front" and "rear" refer to the side closer to the front of the toy car and "rear" refer to the side closer to the rear of the toy car. "Up" and "down" refer to the side closer to the top of the toy car and "down" refer to the side closer to the bottom of the toy car. "Left and right" refer to the directions of the two sides of the toy car.

[0019] Compared with the prior art, this utility model has the following advantages:

[0020] This drifting toy car can automatically drift while driving. It has a high degree of realism and simulation, which increases the playability and fun of the drifting toy car. It also has a simple structure and low production cost. Attached Figure Description

[0025] like Figures 1-4As shown, this drifting toy car includes a frame 1, a shell 2, a driving mechanism 3, a drifting action mechanism 4, two front wheels 5, and two rear wheels 6. The two front wheels 5 are rotatably mounted on the left and right sides of the front of the frame 1, respectively, and the two rear wheels 6 are rotatably mounted on the left and right sides of the rear of the frame 1, respectively. The shell 2 is mounted on the frame 1. The drifting action mechanism 4 includes a support body 40, wheel axles 41, a movable frame 42, a steering shaft 43, a steering wheel 44, a cam shaft 45, a cam 46, and a swing arm 47. The support body 40 is mounted on the frame 1. The wheel axles 41 are rotatably mounted on the support body 40 and are oriented left and right. The wheel axles 41 are connected to the output end of the driving mechanism 3. The two rear wheels 6 are mounted on the left and right ends of the wheel axles 41, respectively. The left end of the movable frame 42 is connected to a first... The connecting shaft 421 is hinged to the support body 40. The steering shaft 43 is rotatably mounted on the movable frame 42 and runs in a front-to-back direction. The steering shaft 43 is perpendicular to the wheel axle 41. The steering shaft 43 and the wheel axle 41 are connected by a first transmission mechanism 48. The steering wheel 44 is fixedly mounted on the steering shaft 43. The camshaft 45 is rotatably mounted on the support body 40 and runs in a vertical direction. The camshaft 45 and the wheel axle 41 are connected by a second transmission mechanism 49. The cam 46 is fixedly mounted on the camshaft 45. The swing arm 47 is located between the cam 46 and the movable frame 42. The middle part of the swing arm 47 is hinged to the support body 40 through a second connecting shaft 471 running in a vertical direction. The rear end of the swing arm 47 contacts the wheel surface of the cam 46, and the front end of the swing arm 47 contacts the right end of the movable frame 42.

[0026] In this embodiment, the rear end of the swing arm 47 is provided with a wedge-shaped portion 472, which is in contact with the wheel surface of the cam 46.

[0027] In this embodiment, the support body 40 is a shell with an inner cavity. The movable frame 42, cam 46, swing arm 47, first transmission mechanism 48, and second transmission mechanism 49 are all disposed in the inner cavity of the support body 40. A mounting port 401 is provided on the bottom plate of the support body 40, and the lower part of the steering wheel 44 extends from the mounting port 401 to the lower side of the support body 40. The support body 40 is used to protect the various components of the drifting action mechanism 4 and also makes the drifting toy car more aesthetically pleasing. An opening 402 is provided on one side of the support body 40, and an operating part 473 is provided at the front end of the swing arm 47. The operating part 473 protrudes from the opening 402 to the outside of the support body 40. The player can manually press the operating part 473 to push the movable frame 42 and the steering wheel 44 upward around the first connecting shaft 421 by using the front end of the swing arm 47, so that the steering wheel 44 disengages from the vehicle's driving surface. The drifting action mechanism 4 also includes a return spring 410. The return spring 410 is disposed between the top plate of the support body 40 and the movable frame 42. The upper end and the lower end of the return spring 410 are respectively connected to the top plate of the support body 40 and the movable frame 42. Under the action of the return spring 410, the movable frame 42 has an upward tendency to move, so that the movable frame 42 can be closely attached to the front end of the swing arm 47.

[0028] In this embodiment, the right end of the movable frame 42 is provided with a first guide slope 422 that gradually slopes upward from left to right, and the front end of the swing arm 47 is provided with a second guide slope 473 that gradually slopes upward from left to right. The second guide slope 473 is located below the first guide slope 422 and contacts and engages with the first guide slope 422. When the front end of the swing arm 47 swings to the left around the second connecting shaft 471, the engagement between the second guide slope 473 and the first guide slope 422 of the swing arm 47 can be used to push the movable frame 42 to swing upward around the first connecting shaft 421, causing the steering wheel 44 to disengage from the vehicle's travel surface.

[0029] In this embodiment, the first transmission mechanism 48 includes a drive gear 481, a transmission shaft 482, an end face gear 483, a first transmission gear 484, and a second transmission gear 485. The drive gear 481 is fixedly mounted on the wheel axle 41. The transmission shaft 482 is rotatably mounted on the support body 40 and runs in a front-to-back direction. The end face gear 483 is fixedly mounted on the rear end of the transmission shaft 482 and meshes with the drive gear 481. The first transmission gear 484 is fixedly mounted on the front end of the transmission shaft 482. The second transmission gear 485 is fixedly mounted on the steering shaft 43 and meshes with the first transmission gear 484. When the drifting toy car is moving, the drive gear 481 rotates under the drive of the wheel axle 41, which then drives the transmission shaft 482 and the first transmission gear 484 to rotate via the end face gear 483, and then drives the steering shaft 43 and the steering wheel 44 to rotate via the second transmission gear 485.

[0030] In this embodiment, the second transmission mechanism 49 includes a worm 491 and a worm wheel 492. The worm 491 is fixedly mounted on the wheel axle 41, and the worm wheel 492 is fixedly mounted on the camshaft 45 and meshes with the worm 491. With this structure, the worm 491 rotates under the drive of the wheel axle 41, and then drives the camshaft 45 and cam 46 to rotate through the worm wheel 492. This allows for a large reduction ratio between the wheel axle 41 and the camshaft 45, enabling the cam 46 to rotate at a slower speed, thus better controlling the drifting toy car's driving state.

[0031] In this embodiment, the driving mechanism 3 is an inertial gearbox, which is mounted on the support 40. The output shaft of the inertial gearbox is connected to the wheel axle 41 via a gear set 31. The inertial gearbox can be driven by inertia without external power, reducing operating costs and improving ease of use and practicality.

[0032] The following is a brief description of the driving process and principle of this drifting toy car:

[0033] When this drifting toy car is in motion, the wheel axle 41 rotates continuously under the drive of the driving mechanism 3, causing the two rear wheels 6 or the two front wheels 5 on it to rotate, making the drifting toy car move forward or backward. At the same time, the wheel axle 41 drives the steering shaft 43 and steering wheel 44 to rotate continuously through the first transmission mechanism 48. Simultaneously, the wheel axle 41 drives the cam shaft 45 and cam 46 to rotate continuously through the second transmission mechanism 49. Utilizing the engagement between the wheel surface of the cam 46 and the rear end of the swing arm 47, the front end of the swing arm 47 swings back and forth around the second connecting shaft 471. Utilizing the engagement between the front end of the swing arm 47 and the guide ramp 422, the movable frame 42 and the steering wheel 44 swing upward or downward around the first connecting shaft 421. The steering wheel 44 is brought into contact with or separated from the vehicle's driving surface (the contact and separation times of the steering wheel 44 and the vehicle's driving surface can be controlled by the wheel surface design of the cam 46), changing the driving state of the drifting toy car: when the steering wheel 44 swings downward under the drive of the movable frame 42 until it contacts the vehicle's driving surface, the rotating steering wheel 44 will change the driving direction of the drifting toy car, so that the drifting toy car will automatically drift during driving; when the steering wheel 44 swings upward under the drive of the movable frame 42 until it separates from the vehicle's driving surface, the drifting toy car is in a normal driving state. Thus, this drifting toy car can automatically drift at intervals during driving, with high fidelity and simulation, increasing the playability and fun of the drifting toy car.
