[ detailed description ] embodiments

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a vehicle-mounted moving doll 100, wherein the vehicle-mounted moving doll 100 may be placed on a driving seat as a car ornament, thereby enhancing the aesthetic appearance of the interior space of the car.

The vehicle-mounted moving doll 100 comprises a base 1, a transparent outer cover 2 fixed on the base 1, a moving component 3 contained in the transparent outer cover 2 and an electret microphone 4 installed on the base 1.

In the embodiment, the base 1 is rectangular, and is directly placed on the automobile driving platform, so that the stability can be kept well, and the base is not easy to topple.

Transparent dustcoat 2 is fixed in the top of base 1, it is preferred, transparent dustcoat 2 adopts ya keli material to make, has better transparency, chemical stability and weatherability to workable, the outward appearance is graceful. The transparent outer cover 2 and the base 1 are matched to enclose a closed accommodating space, and the motion state of the motion assembly 3 can be observed through the transparent outer cover 2.

The transparent outer cover 2 comprises a top wall 21 arranged in parallel with the base 1 at intervals and a side wall 22 bent and extended from the edge of the top wall 21 to the direction close to the base 1, wherein the side wall 22 is fixedly connected with the base 1.

The moving assembly 3 is accommodated in the accommodating space and fixed on the base 1. Specifically, the moving assembly 3 includes a coil 31, a bracket 32 fixed at the center of the coil 31, and a magnetic ball 33 sleeved on the bracket 32, wherein the coil 31 generates magnetic force after being electrified, and drives the magnetic ball 33 to slide up and down along the bracket 32.

The bracket 32 is made of a non-metallic material. The magnetic ball 33 is provided with a through hole along the diameter direction in a penetrating manner, the bracket 32 is cylindrical, the diameter of the through hole is slightly larger than the outer diameter of the bracket 32, and the bracket 32 correspondingly penetrates through the through hole.

After the coil 31 is energized, the coil 31 and the magnetic ball 33 have the same-name magnetic poles opposite to each other, specifically, in this embodiment, a side of the coil 31 facing the magnetic ball 33 is an N pole, a side of the coil 31 away from the magnetic ball 33 is an S pole, a side of the magnetic ball 33 close to the coil 31 is an N pole, and a side of the coil 31 away from the magnetic ball 33 is an S pole, and the coil 31 and the magnetic ball 33 have the same-name magnetic poles opposite to each other and repel each other, so that the magnetic ball 33 is driven to move in a direction away from the coil 31.

The electret microphone 4 is installed on the outer side of the base 1 and used for collecting sound and converting sound signals into electric signals, and the electret microphone 4 is connected with the coil 31.

A control circuit is arranged between the electret microphone 4 and the coil 31, the control circuit comprises a power circuit, a microphone amplifying circuit and a coil indicating circuit, a capacitor C1 is used for power BT filtering, an electret microphone MIC converts a sound signal into an electric signal, the electric signal is coupled to a triode NPN1 through a capacitor C2 for amplification, and the triode NPN2 drives the coil 31 to work. It should be noted that the power circuit may be powered by a battery, or may be powered directly from an OBD interface of the vehicle. The corresponding circuit connections are implemented by conventional technical means in the art, and the present invention is not described in detail herein.

The electret microphone 4 can collect sounds in the vehicle, such as conversation sounds, music sounds or other noises, and with the change of the sound, the input current of the coil 31 also changes, and further the magnetic field strength of the coil 31 also changes, and further the drive of the magnetic ball 33 also changes. By adjusting the transistor NPN1, the amplification can be changed at a reasonable level, so that the driving force generated by the coil 31 matches the gravity of the magnetic ball 33.

Specifically, the vehicle-mounted moving doll 100 is used as follows: when the sound is small, the input current of the coil 31 is small, the driving force to the magnetic ball 33 is smaller than the gravity of the magnetic ball 33, and the magnetic ball 33 is kept at the lower end of the bracket 32; when the sound reaches the preset value, the driving force of the coil 31 to the magnetic ball 33 is greater than the gravity of the magnetic ball 33, the magnetic ball 33 moves upwards along the bracket 32, the sound continues to increase, and the magnetic ball 33 continues to rise until abutting against the transparent cover 2.

Further, an alarm 221 and a touch switch 222 connected with the alarm 221 are arranged at a position where the top wall 22 is connected with the bracket 32, the magnetic ball 33 touches the transparent cover 2 and then touches the touch switch 222, and the alarm 221 correspondingly emits an alarm sound, for example: "A sound is too big! The method and the device improve the personnel in the vehicle and reduce the corresponding sound so as to avoid influencing the driving of the driver.

Furthermore, one end of the magnetic ball 33 far away from the coil is provided with a buffer member 331, the buffer member 331 is fixedly connected with the magnetic ball 33, preferably, the buffer member 331 is made of a flexible material, and when the magnetic ball 33 touches the transparent cover 2, the buffer member can play a role in buffering, so that the transparent cover 2 or the touch switch 222 is prevented from being damaged due to too large impact.

As the sound in the vehicle fluctuates, the magnetic balls 33 move up and down along the stand 32, increasing the interest of the vehicle-mounted moving doll 100. Meanwhile, the motion state of the magnetic ball 33 is adjusted according to the sound in the vehicle, so that the playability is high, and the aesthetic fatigue is not easy to occur.

While the foregoing is directed to embodiments of the present invention, it will be understood by those skilled in the art that various changes may be made without departing from the spirit and scope of the invention.
