Description

Technical Field

[0001] The utility model belongs to the technical field of twisting cars, and particularly relates to a steering limiting structure of a twisting car. Background Art

[0002] The twisting car, also known as the fitness and entertainment car, does not require charging, fuel, winding, or pedaling. It can be driven by just shaking the steering wheel left and right with your hands. Its driving principle adopts the centrifugal law and the curve force law. It does not require electricity, fuel, or spring drive and can move freely.

[0003] Tricycles are widely used by infants and children, but when children use them for the first time, especially toddlers, they have less strength and it is difficult for them to control the forward angle when shaking the steering wheel left and right to drive. It is also difficult for children to get out of the spinning state, which makes accidents prone to occur. In addition, when adults or external force simply push the tricycle forward, the front wheels are easy to turn, and the tricycle is easy to spin in circles. Children need to hold the steering wheel to ensure that the tricycle moves in a straight line or forward.

[0004] The existing Chinese utility model patent CN 214729365 U discloses a steering power-off electric twisting car. When the metal strip moves to the recess on the second connecting ring, the metal strip loses contact with the second connecting ring, and the power transmission is terminated. The driving device stops driving the driving wheel, and the electric twisting car slowly stops after losing power. The insulating rubber pad filled in the recess can isolate the power transmission to prevent the generation of electric sparks; the size of the recess can be set according to the steering angle to be controlled, which is convenient for setting for children of different ages; the technical solution is to adjust the steering angle by the size of the recess. Although the angle can be limited, each angle requires a different model of twisting car to achieve it, and collisions are prone to occur during the limiting process, there are abnormal sounds, and the limiting is relatively stiff. This is inconvenient for children to use; at the same time, the structure still cannot solve the problem that the twisting car is easy to turn in circles when pushed by external force, and the child needs to hold the steering wheel to move forward in a straight line.

[0005] Therefore, a twisting car is needed which is convenient for the current twisting car to steer and convenient for children to shake the steering wheel left and right. Summary of the invention

[0006] In order to overcome the defects in the prior art, the purpose of the utility model is to provide a steering limit structure of a twisting car which is convenient for children to shake the steering wheel left and right and to control the shaking angle.

[0029] The present invention will be further described below with reference to specific embodiments of the invention:

[0030] See also Figures 1 to 6As shown, a steering limit structure of a twisting car comprises a car body 1, a steering wheel 2 movably arranged at the front end of the car body 1, and a front wheel assembly connected to the lower end of the steering wheel 2, wherein the front wheel assembly comprises a fixing frame 31 fixedly connected to the lower end of the steering wheel 2, and a driving wheel 32 is arranged on the fixing frame 31. In this embodiment, the fixing frame 31 is connected and fixed by a rotating shaft 21 on the steering wheel 2; driving wheels 32 are arranged on both sides of the rear end of the fixing frame 31, and an auxiliary wheel 33 is arranged at the front end of the fixing frame 31. At the same time, rear wheels 13 are arranged on both sides of the rear end of the car body 1, and the rear wheels 13 are preferably universal wheels, which are convenient for the car to shake left and right. A first mounting seat 4 is arranged on the fixing frame 31, and a second mounting seat 5 is arranged on the car body 1. The first mounting seat 4 and the second mounting seat 5 are connected and fixed by an elastic member 6, and the elastic member 6 enables the car body 1 and the front wheel assembly to keep moving straight forward when the steering wheel 2 is not rotated by external force.

[0031] In this embodiment, the car body 1 and the fixing frame 31 are connected by an elastic member 6. This connection is an elastic connection. The elastic member 6 can limit the angle of the child shaking the steering wheel 2 left and right. When the steering wheel 2 is turned at an excessive angle, the elastic member 6 prevents it from continuing to turn, so that the steering wheel 2 is swung within a certain swing range, avoiding the situation where the child makes an operating error or the steering wheel 2 spins in place due to unfamiliarity with the operation, which can improve the operation success rate of beginners and reduce operating errors; at the same time, the elastic member 6 can also have a certain restoring force to help the steering wheel 2 reset when shaking and resetting, and the reset is labor-saving. When the twisting car needs to be used as an ordinary stroller, the elastic member 6 keeps the car body 1 and the front wheel assembly moving straight forward when the steering wheel 2 is not turned by external force. At this time, when the adult pushes the twisting car, the child does not need to hold the steering wheel 2 all the time to prevent the steering wheel 2 from turning, and it is also convenient for the adult to use the twisting car as an ordinary stroller.

[0032] The elastic member 6 in this embodiment is detachably connected and fixed to the first mounting seat 4 and the second mounting seat 5. The elastic member 6 can be detached from the fixed connection with either the first mounting seat 4 or the second mounting seat 5. The elastic member 6 can also be detached from both mounting seats and the elastic member 6 can be disassembled and stored separately.

[0033] When the elastic member 6 is not needed to fix the first mounting seat 4 and the second mounting seat 5, the elastic member 6 can be removed to release the restriction on the steering wheel 2. At this time, the twisting car in this embodiment can be shaken at any angle like conventional twisting cars on the market.

[0034] The first mounting seat 4 is provided with a first mounting hole 41 , the second mounting seat 5 is provided with a second mounting groove 51 , one end of the elastic member 6 is connected to the first mounting hole 41 , and the other end of the elastic member 6 is detachably connected to the second mounting groove 51 .

[0035] The elastic member 6 can be an elastic ring, which is an O-ring made of rubber, or a spring, which is a tension spring; when a spring is used, the two ends of the spring can be detachably connected to the first mounting hole 41 and the second mounting groove 51. Elastic members 6 made of other materials are within the protection scope of this embodiment as long as they can keep the vehicle body 1 and the front wheel assembly moving straight forward when the steering wheel 2 is not rotated by external force.

[0036] In order to facilitate the storage of the elastic member 6 after being disassembled from the second mounting groove 51, a receiving cavity for placing the elastic member 6 is provided on the first mounting seat 4. The elastic member 6 is stored in the receiving cavity to avoid loss of the elastic member 6. The elastic member 6 can be taken out and used when it is needed later.

[0037] There are other ways to store the elastic member 6:

[0038] Method 1:

[0039] The elastic member 6 is an elastic ring, the outer peripheral wall of the first mounting seat 4 is adapted to the inner wall of the elastic ring, the elastic member 6 is clamped on the outer peripheral wall of the first mounting seat 4, and the elastic member 6 is directly put on the outer peripheral wall of the first mounting seat 4, and the first mounting seat 4 is tightly held by the elastic force of the elastic member 6 itself.

[0040] Method 2:

[0041] The elastic member 6 is an elastic ring, and a shielding edge 43 is extended outwardly on the outer peripheral wall of the first mounting seat 4. The elastic member 6 is sleeved outside the first mounting seat 4 and is prevented from being separated from the first mounting seat 4 by the shielding edge 43. The elastic member 6 is restricted between the first mounting seat 4 and the fixing frame 31 by the shielding edge 43, so as to prevent the elastic member 6 from being separated from the upper end of the first mounting seat 4 and to prevent the elastic member 6 from swinging in the storage state.

[0042] In this embodiment, a mounting groove 42 with an opening toward the upper end surface of the fixing frame 31 is provided on the first mounting seat 4. After the first mounting seat 4 is connected and fixed to the fixing frame 31, the mounting groove 42 abuts against the upper end surface of the fixing frame 31 to form a first mounting hole 41. One end of the elastic member 6 is sleeved in the first mounting hole 41, and the elastic member 6 can swing around the first mounting hole 41. The first mounting hole 41 fixes the elastic member 6 and prevents it from detaching from the first mounting hole 41, which can effectively avoid the loss of the elastic member 6 and is also convenient for users to store.

[0043] The first mounting seat 4 is fixedly connected to the fixing frame 31 by screws; the second mounting seat 5 is fixedly connected to the vehicle body 1 by screws; the screw fixing method facilitates the installation and fixation of the first mounting seat 4 and the second mounting seat 5, and is convenient for production and installation. At the same time, in order to prevent the first mounting seat 4 and the second mounting seat 5 from rotating after being fixed, the mounting seats can be fixed by setting at least two screws, or by using special-shaped limit columns for plug-in connection and then fixing with screws, which can also limit rotation.

[0044] At the same time, a push rod 11 is detachably provided at the rear end of the vehicle body 1, and the push rod 11 is plugged into the vehicle body 1 by an elastic snap-fit ​​method. When an adult needs to push the vehicle, the push rod 11 is plugged into the vehicle body 1 for use. The plugging of the push rod 11 on the vehicle body 1 does not affect children's use of the twisting vehicle. A pedal 12 extending outward is provided at the front end of the vehicle body 1, and both feet can be placed on the pedal 12 when in use.

[0045] When the twisting car is in use, the elastic member 6 is first unfolded, one end of the elastic member 6 is connected to the first mounting hole 41, and the other end is engaged with the second mounting groove 51, so that the car body 1 and the front wheel assembly are integrated, and the two keep moving straight when the steering wheel 2 is not rotated by external force. When the child swings the steering wheel 2 left and right, the elastic member 6 can limit the angle of the child's shaking of the steering wheel 2 left and right, so that the steering wheel 2 swings within a certain swing range. At the same time, when the steering wheel 2 is reset, the restoring force of the elastic member 6 helps the steering wheel 2 to reset; it is convenient for children to learn and use. When the twisting car needs to be used as an ordinary cart, because the elastic member 6 keeps the car body 1 and the front wheel assembly moving straight when the steering wheel 2 is not rotated by external force, the steering wheel 2 will not rotate 360 ​​degrees when the adult pushes the twisting car, which is convenient for the adult to use the twisting car as an ordinary cart. When the swing angle does not need to be limited, the elastic member 6 can be disconnected from the second mounting groove 51, and it can be used like an ordinary twisting car.

[0046] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
