As shown in fig. 1 to fig. 2, the utility model discloses a vibrations feedback system for car, including frame 4, set up in rectilinear movement mechanism 1 in the frame 4 the utility model discloses in preferably will rectilinear movement mechanism 1 sets up to electromagnetic drive mechanism, and its structure is as shown in fig. 1, including armature 11, the cover is established coil 12 of armature 11 periphery and with coil 12 electric connection's wire 13. To ensure the stability of the coil 12, a coil support 121 is placed in the frame 4, around which coil support 121 the coil 12 is wound. The armature 11 is located in the inner diameter of the coil support 121 and reciprocates in the axial arrangement direction of the coil support 121.

The linear moving mechanism 1 is used for driving the guide shaft 2 to reciprocate so as to damp the pad 3. The guide shaft 2 is preferred to adopt the phenolic aldehyde material to make, and it has characteristics such as waterproof, insulating and high temperature resistant, promptly the utility model discloses a vibration feedback system for car can adapt to the adverse circumstances of high temperature and high humidity, has higher protection level. The free end of the guide shaft 2 is inserted into the vibration damping pad 3, and the guide shaft and the vibration damping pad are coaxially arranged. The guide shaft 2 is located on one side of the armature 11 and is arranged coaxially with the armature 11.

First embodiment, as shown in fig. 1 and 2, the damping pad 3 can be connected directly or indirectly to the frame 4, with its outer side always in contact with the customer premises. The guide shaft 2 is displaced relative to the damping pad 3. Specifically, when a user or an external force touches a touch screen of the client, the wire 13 is conducted, the coil 12 is electrified and drives the armature 11 to move in the forward direction (towards the vibration damping pad 3), so as to drive the guide shaft 2 to move until the free end of the guide shaft 2 abuts against the vibration damping pad 3, the vibration damping pad 3 transmits acting force applied to the client, and finally, vibration is generated through the touch screen to prompt that a key of the user is triggered.

Example two: the vibration damping pad 3 is fixedly connected with the guide shaft 2. When a user or an external force touches the touch screen of the client, the conducting wire 13 is conducted, the coil 12 is electrified and drives the armature 11 to move in the forward direction (towards the vibration damping pad 3), so that the guide shaft 2 and the vibration damping pad 3 are driven to move until the outer side of the vibration damping pad 3 is abutted against the client, and finally, the touch screen generates vibration to prompt the user that the key is triggered.

In order to prevent the vibration damping pad 3 from being damaged in the contact process with the guide shaft 2 and the client side and/or damage the guide shaft 2 and the client side system, the vibration damping pad 3 is preferably made of high-elasticity rubber, so that the design has the advantages that firstly, the damage to the guide shaft 2 and/or the vibration damping pad 3 and/or the client side system can be effectively avoided, the elastic fatigue is reduced, and the service life is prolonged; secondly, the self characteristics of the high-elasticity rubber play a role in vibration reduction and buffering, and the vibration sense (touch sense) can be effectively fed back to the client; in addition, the noise generated by vibration can be effectively reduced, and experiments prove that the vibration damping pad made of high-elasticity rubber can control the noise to be below 30 decibels.

For guaranteeing guiding axle 2 can not produce in the removal process and rock, the free end of guiding axle 2 runs through rather than the magnetic core 14 of coaxial setting, just magnetic core 14 is fixed in the coil bracket 121, its fixed mode is not the utility model discloses a key, do not do here and describe repeatedly. As shown in fig. 3, the magnetic core 14 is formed by integrally and coaxially arranging a circular table portion 141, a main body 142 and a cylindrical portion 143. The armature 11 moves forward and then abuts against the boss 141 and one end of the main body 142 of the core 14. As shown in fig. 4, a groove 1101 matching with the boss 141 is formed inward at one end of the armature 11 contacting the core 14, and the guide shaft 2 penetrates through a bottom end of the groove 1101 and is inserted into an axial center of the armature 11.

As shown in fig. 1, the spring has a circular truncated cone shape, and the diameter of the spring gradually decreases from the frame 4 to the damping pad 3. The spring 304 is used to secure a distance between the damping pad 3 and the frame 4, while the damping pad 3 defines a moving direction and a moving range of the guide shaft 2. Of course, in addition to the above, the length of the damping pad 3 may be increased, in which the damping pad 3 is fixed to the outside of the frame 4 and has a length equal to the sum of the initial state length of the spring 304 and the bottom height of the damping pad 3 in the above embodiment.

When the customer end is not touched, the armature 11 moves in the opposite direction (moves in the opposite direction of the magnetic core 14), and at least part of the armature can penetrate through the frame 4, so as to ensure the coaxiality of the armature and the magnetic core 14, and simultaneously avoid the armature 11 from being separated from the frame 4. The frame 4 further comprises an end cover 41 protruding from a side surface thereof, and the end cover 41 is located at an end surface of the armature 11 and is coaxially arranged with the armature 11, and the two are connected through a spring. A protrusion 411 inserted into the axis of the armature 11 is formed in the end cap 41, one end of the spring is disposed on the periphery of the protrusion 411 and is fixedly connected to the end cap 41, and the other end of the spring is fixed in the armature 11, specifically, a slot 1102 is formed inward at one end of the armature 11 away from the magnetic core 14, and the spring is accommodated in the slot 1102 and is fixedly connected to the slot 1102. When the coil 12 is de-energized, the armature 11 is reset (moved in the opposite direction) under the force of the spring. The clamping groove 1102 is communicated with the groove 1101 through a convex connecting hole 1103, and one end of the connecting hole 1103 with a larger bore diameter is communicated with the groove 1101 and used for accommodating the guide shaft 2; the end with the smaller aperture is communicated with the clamping groove 1102.
