Description

Technical Field

[0001] The utility model relates to the technical field of linear vibration motors, in particular to a linear vibration motor used for a racing simulator. Background Art

[0002] Linear vibration motors are used in racing simulators to simulate the vibrations experienced when driving a real racing car, such as the vibrations of car tires, brake pedals, clutch pedals, and accelerator pedals.

[0003] The existing linear vibration motors on the market are large in size and are not suitable for installation in compact simulators. They have great limitations on application space. The rotors of the existing linear vibration motors on the market are heavy, and the energy required for high-frequency vibration is large, making them unsuitable for applications with higher frequencies. Low-frequency speakers need to be controlled by low-frequency amplifiers and require audio signal control, which is costly and technically complex. Summary of the Invention

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a linear vibration motor for a racing simulator.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A coil bracket is sleeved on the outer side of the magnet, and coil one and coil two are respectively wound in the coil slots on both sides of the coil bracket.

[0008] Preferably, the outer shell is composed of a middle shell, a bottom shell and a top shell, and shaft mounting holes are provided at the center positions of the inner walls on opposite sides of the bottom shell and the top shell.

[0009] Preferably, the silicone gasket with a cone includes a silicone gasket and cones equidistantly arranged on the silicone gasket, and the silicone gasket and the cone are an integrally formed structure.

[0010] Preferably, a wire entry hole is opened on one side of the top shell, and a power line is installed in the wire entry hole.

[0011] Preferably, the power line is connected to coil one and coil two, and the power line is connected to a reverse switch.

[0012] Preferably, the gasket and the cone-shaped silicone gasket are both sleeved in the coil bracket, and the gasket is made of magnetic conductive material.

[0013] The beneficial effects of the utility model are:

[0014] The vibration motor designed in this scheme is more compact, lighter and has a wider range of applications than the vibration motors on the market. The mover designed in this scheme is light in weight and can be used for higher vibration frequencies;

[0015] The linear vibration motor can change the direction of current passing through the coil through a reverse switch to control the movement of the actuator. It does not require control through an amplifier and audio signal, and is simple to control and low in cost. BRIEF DESCRIPTION OF THE DRAWINGS
