Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of toy wheels, in particular to a toy wheel with side lamps. BACKGROUND

[0002] In the prior art, indoor toy cars such as remote control cars and electric omnidirectional cars can increase the fun when playing in the living room. Outdoor toy cars with lighted wheels can make it easier for children to find the toy car and also increase the aesthetic appeal and uniqueness of the toy car. The general power supply method is battery power supply: using ordinary dry batteries or rechargeable batteries such as common AA batteries, AAA batteries, or lithium batteries, which are installed inside the toy car wheel or in the battery compartment of the toy car, providing power for the lights through the circuit connection, or charging through a USB cable or a dedicated charger, which can be used for a period of time after charging. This method is more environmentally friendly and economical, and is commonly used in some electric toy cars. There are also self-generating: for example, flashing wheels generate electricity through the internal power generation structure when the wheels roll, without the need for additional battery power.

[0003] The prior art, such as Publication No. CN209738702U, provides a flashing roller, which includes a wheel shaft, a wheel body and a magnetic core, and an electric conductor fixed to the wheel body and corresponding to the outer periphery of the magnetic core. The wheel shaft is provided with an embedding groove at the position where the magnetic core is installed, and the embedding groove contains a resilient member. The outer surface of the resilient member protrudes from the embedding groove and elastically abuts the inner ring surface of the magnetic core. By setting the embedding groove at the position where the magnetic core is installed on the wheel shaft to accommodate the resilient member, the outer surface of the resilient member also protrudes from the embedding groove to abut the inner ring surface of the magnetic core. With the appropriate elastic deformation of the resilient member, the gap between the magnetic core and the wheel shaft can be effectively avoided, making the magnetic core and the wheel shaft more secure, and thus the flashing roller can effectively cut the magnetic lines of the magnetic core to generate current to make the corresponding LED light emit light.

[0004] Existing products such as twist cars, children's exercise cars, scooters, roller shoes, and roller skates use flashing rollers to enhance the cool and stylish look. The LED lights on the surface of the wheel body are lit, but in actual use, the surface of the wheel body will have a lot of scratches after long contact with the ground, causing the light transmittance to decrease. Some use a whole transparent material wheel body, but due to the large thickness of the light that needs to penetrate, the light will also be weakened. In view of this, we propose a toy car wheel with side lamps. SUMMARY

[0005] The utility model discloses a toy car wheel with side light, which solves the problem of the decrease of light transmittance caused by a large number of scratches on the surface of the wheel body after long-time contact with the ground during actual use.

[0006] To achieve the above object, the utility model provides the following technical scheme.

[0007] A toy car wheel with side light, comprising a support shaft, an inner wheel fixedly sleeved on the outer wall of the support shaft, an outer wheel rotatably sleeved on the outer wall of the inner wheel, and a flashing mechanism arranged on the side surface of the outer wheel.

[0008] The flashing mechanism comprises a circuit board fixedly connected to one end of the inner wall of the outer wheel, a plurality of flashlights fixedly connected to the circuit board and extending to the outside of the outer wheel, and a lampshade fixedly connected to the position of the outer part of the outer wheel where the flashlights are located.

[0009] Preferably, a retaining ring is fixedly connected to the position of the outer wall of the outer wheel where the lampshade is located, for protecting the lampshade.

[0010] Preferably, a rotating ring is rotatably connected to the central position of the outer wall of the outer wheel, a plurality of cleaning rods are fixedly connected to the outer wall of the rotating ring, and a rubber cleaning strip is arranged at the position where the cleaning rods contact the lampshade.

[0011] Preferably, the cleaning rod is composed of a connecting rod, a sliding sleeve, a tension spring and a clamping head, the connecting rod is fixedly connected to the outer wall of the rotating ring, the sliding sleeve is slidably connected to the outer wall of the connecting rod, the tension spring is fixedly connected to the position between the sliding sleeve and the connecting rod, and the tension spring is fixedly connected to the end of the sliding sleeve close to the rotating ring.

[0012] Preferably, a plurality of clamping grooves are formed in the inner wall of the retaining ring, and the clamping grooves and the lampshade are arranged in a staggered manner, and the clamping grooves are used for limiting the clamping head.

[0013] Preferably, the power generation mechanism comprises a winding stator fixedly connected to the inner wall of the outer wheel, a winding rotor arranged in the winding stator, and the winding rotor is fixedly connected to the support shaft and located in the inner wheel.

[0014] Preferably, the winding stator, the wire and the circuit board are electrically connected, for outputting electric energy to the flashlights for operation.

[0015] By means of the above technical scheme, the utility model provides a toy car wheel with side light. At least the following beneficial effects are achieved:

[0016] The utility model discloses a flash lamp is arranged on the side of the outer wheel, which can avoid the problem that the surface of the conventional wheel body will be scratched after long time contact with the ground, thus reducing the penetration of light. The diamond-shaped protrusions on the inner side of the lamp shade can change the direction of light, redirect the light scattered in other directions, and improve the brightness of the light beam. The diamond-shaped protrusions also have a certain scattering effect, which improves the brightness of the light from the perspective of the observer.

[0017] When the outer wheel rolls, the rotational speed difference between the rotating ring and the outer wheel will cause the cleaning rod to rotate slowly, which can wipe the surface of the lamp shade and avoid the influence of dust on the light transmittance. When the outer wheel rotates at a high speed, the friction between the cleaning rod and the rotating ring and the outer wheel will make the rotation speed faster. The centrifugal force generated by the high speed will stretch the tension spring, and the chuck will be clamped into the clamping groove to limit the movement of the cleaning rod. This can prevent the rubber cleaning strip of the cleaning rod from being easily worn out. BRIEF DESCRIPTION OF DRAWINGS
