Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically a dual-stage damping voice coil vibration motor for racing simulation. Background Technology

[0002] Vibration motors are widely used in racing simulators and virtual reality devices to provide force feedback and immersive experiences. Currently, vibration motors primarily generate tactile feedback through mechanical vibration and are commonly found in devices such as game controllers and cockpit simulators. These motors are typically installed in locations such as pedals, steering wheels, or seats, receiving sensor signals to simulate road vibrations, engine vibrations, or collision effects during real driving. Voice coil motors, due to their fast response speed and high control precision, are increasingly being used in high-end simulation equipment, capable of more realistically reproducing the various vibration characteristics of a race car during driving. With the development of virtual reality technology, the performance requirements for vibration motors are constantly increasing, demanding that they achieve more delicate and realistic vibration feedback effects.

[0003] Existing vibration feedback methods mostly rely on rotary eccentricity or single-stage spring damping, which makes it difficult to simultaneously achieve large stroke and high-frequency vibration suppression. Furthermore, the guiding and sealing effects are poor, resulting in noise, vibration, and guiding deviation. Therefore, in view of the above situation, there is an urgent need to develop a dual-stage damping voice coil vibration motor for racing simulators to overcome the shortcomings in current practical applications.

[0010] The second-stage shock absorption mechanism includes a spring that passes through the pressure block and has its bottom end attached to the permanent magnet ring.

[0011] The guide assembly includes a linear bearing, in which the permanent magnet ring moves axially. The linear bearing is positioned by the inner circle of the middle shell, and the upper and lower shells clamp and lock it in place.

[0012] The sealing assembly includes a second sealing ring disposed on the mating surface between the upper shell and the middle shell, and a first sealing ring disposed on the mating surface between the middle shell and the lower shell.

[0013] As a further embodiment of this utility model: the lower shell is provided with a limiting boss that cooperates with the linear bearing, and the middle shell and the upper shell are axially positioned through a concave-convex nesting structure.

[0014] As a further embodiment of this utility model: the pressure block is connected to the permanent magnet ring by a screw, and the coil is fixed to the lower shell by a screw.

[0015] As a further embodiment of this utility model: the mounting hole for the adapter plate on the lower shell is a threaded connection hole, which can be fixedly connected to the racing simulator pedal or virtual reality device through the adapter plate.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] Please see Figures 1-4 This utility model provides a dual-stage damping voice coil vibration motor for simulating racing, comprising:

[0030] The housing assembly consists of a detachably connected upper shell 2, middle shell 1, and lower shell 3;

[0031] Motor 4 is located inside the housing assembly. Motor 4 includes a permanent magnet ring 4.1 and a coil 4.2. The coil 4.2 is fixedly connected to the lower housing 3. The permanent magnet ring 4.1 moves linearly.

[0032] The first-stage damping mechanism includes a rubber ring 10 sleeved on the lower end of the coil and a damping rubber ring 9 sandwiched between the pressure block 5 and the upper shell 2.

[0033] The second-stage shock absorption mechanism includes a spring 8, which passes through the pressure block 5 and has its bottom end attached to the permanent magnet ring 4.1.

[0034] The guide assembly includes a linear bearing 6, in which the permanent magnet ring 4.1 moves axially. The linear bearing 6 is positioned against the inner circle of the middle shell 1, and is clamped and locked by the upper shell 2 and the lower shell 3.

[0035] The sealing assembly includes a second sealing ring 7.2 disposed on the mating surface of the upper shell 2 and the middle shell 1, and a first sealing ring 7.1 disposed on the mating surface of the middle shell 1 and the lower shell 3.

[0036] In one embodiment of this utility model, please refer to Figures 1-4The lower shell 3 is provided with a limiting boss that cooperates with the linear bearing 6, and the middle shell 1 and the upper shell 2 are axially positioned through a concave-convex nesting structure.

[0037] The pressure block 5 is connected to the permanent magnet ring 4.1 by screw 11, and the coil 4.2 is fixed to the lower shell 3 by screw 12.

[0038] The adapter plate mounting hole 15 provided on the lower shell 3 is a threaded connection hole, which can be fixedly connected to the racing simulator pedal or virtual reality equipment through the adapter plate.

[0039] The middle shell 1 and the lower shell 3 are fixedly connected by a screw 14, which passes through the mounting hole of the lower shell 3 and is screwed into the threaded hole of the middle shell 1.

[0040] During use, the rubber ring 10 is fitted onto the coil end 4.2 below the motor 4. The pressure block 5 is connected to the magnetic ring end 4.1 above the motor 4 via screw 11. Two springs 8 are inserted into the other two holes of the pressure block 5 to dampen vibration. The damping rubber ring 9 is fitted onto the springs 8 and attached to the pressure block 5. The coil 4.2 is fixed to the lower shell 3 via screw 2 12. The linear bearing 6 is attached to the lower shell 3 along the central axis. The sealing ring 7.1 passes through the linear bearing 6 and is attached to the limiting protrusion of the lower shell 3. The middle shell 1 is attached to the limiting groove of the lower shell 3 and the middle shell 1 along the central axis, and is fixed with screw 4 14 after pressing the sealing ring 7.1. The sealing ring 7.2 is installed in the groove above the middle shell 1. The limiting protrusion of the upper shell 2 and the limiting groove of the middle shell 1 are used to press the sealing ring 7.2 and then fixed with screw 3 13.

[0041] Furthermore, when stationary, the two springs 8 press against the upper shell 2 to pre-compress the stroke, and the motor permanent magnet ring 4.1 moves up and down to make the vibration smoother. When the motor permanent magnet ring 4.1 and the pressure block 5 move upward to the limit position, the shock-absorbing rubber ring 9 hits the upper shell 2 to achieve shock absorption and reduce impact noise. When moving downward to the limit position, it first hits the shock-absorbing rubber ring 10 to achieve shock absorption and reduce impact noise, thus forming a two-stage shock absorption.

[0042] In addition, the low-friction linear bearing 6 ensures the stability of the permanent magnet ring 4.1 during linear motion. The sealing rings 7.1 and 7.2 at the connection points between the upper shell 2, lower shell 3, and middle shell 1 provide shock absorption and sealing, further reducing the impact of noise and vibration on the equipment. The adapter plate mounting hole 15 of the lower shell 3 allows it to be fixed via the adapter plate and then installed on other equipment. When the user binds the remote sensing data trigger signal, the motor 4 will start vibrating to alert the user.

For example, they can refer to welded connections, bolted connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity.
