[0003] Existing integrated touch panel assembly solutions have many problems in actual application and cannot meet actual needs. The relevant problems are mainly concentrated in the following points:

[0004] The touch technology in existing integrated touch panel assembly solutions generally uses a capacitive diaphragm attached to the back of the touch panel, and uses the change in the capacitance signal of the capacitive diaphragm to determine the trigger state. This touch panel technology is prone to false triggering and other operations, and has a low level of false trigger protection.

[0005] The vibration feedback technology in existing integrated touch panel assembly solutions generally uses multiple linear motors or rotor motors as vibration actuators, which are relatively expensive.

[0006] The vibration direction in existing integrated touch panel assembly solutions is designed to be parallel to the panel, or a connector is used to transmit the vibration to the panel, resulting in a low vibration frequency and a weak vibration sensation. Utility Model Content

[0040] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] See also Figure 1-2 As shown, a touch-pressure operation tactile feedback mechanism includes a touch-pressure control component, the touch-pressure control component is provided with a touch-pressure area 2.1 for a user to touch and press, and a control unit that responds to the touch-pressure operation;

[0042] The touch-pressure operation tactile feedback mechanism further includes: a tactile feedback component, the tactile feedback component includes an abutment portion 3 and a drive unit, the abutment portion 3 is arranged below the touch-pressure area 2.1;

[0043] The driving unit is electrically connected to the control unit. The control unit receives a response and drives the contact portion 3 to move up and down reciprocatingly through the driving unit. The contact portion 3 reciprocates in contact with and out of contact with the touch area 2.1 to provide a touch feeling in the touch area 2.1.

[0044] When the touch area 2.1 is touched and pressed, the control unit responds to the touch operation and is electrically connected to the drive unit. The drive unit drives the contact portion 3 to move up and down reciprocatingly, so that the contact portion 3 and the touch area 2.1 are reciprocally in contact and out of contact. During this process, the touch area 2.1 is provided with a touch feeling, and the user can know that the touch operation has been performed.

[0045] Compared with the existing tactile feel providing structure, this device can provide a clearer and more intuitive tactile feel in the touch pressure area 2.1, and the user experience is better.

[0046] The driving unit includes an armature 6 and an electromagnetic module 7 that drives the armature 6 to move up and down;

[0047] The armature 6 is transmission-connected to the abutting portion 3 .

[0048] The electromagnetic module 7 and the armature 6 are combined to serve as a power source. Under the control of the control unit (PCBA control chip and software program), the electromagnetic module 7 can drive the armature 6 to move at a certain frequency and amplitude, thereby obtaining a corresponding vibration amplitude;

[0049] After the above improvements, after the user touches and presses the operation, the electromagnetic module 7 drives the armature 6 to move back and forth up and down, and drives the abutment part 3 to move back and forth up and down, which has good controllability, stable and reliable operation, and the abutment part 3 can move up and down at a high frequency, which can provide a clear and delicate feel, further enhancing the user experience.

[0050] The armature 6 is provided with a bracket 6.1. The abutting portion 3 is a rod body which is provided on the bracket 6.1. The upper end of the axis of the rod body is perpendicular to the contact and pressure area 2.1, and the lower end of the axis is perpendicular to the bracket 6.1.

[0051] After the above improvement, a rod body vertically arranged between the touch and pressure area 2.1 and the bracket 6.1 is used as the abutment part 3, which has a good force transmission time and transmission performance, and can quickly provide a clear feel in the touch area.

[0052] The head of the rod body is also provided with a rubber cap 3.1. The rubber cap 3.1 contacts the touch and pressure area 2.1 to prevent the metal guide rod from hard contact with the panel 2 to generate vibration noise, further improving the user experience.

[0053] See also Figure 2-12 As shown, a panel assembly includes a tactile feedback mechanism using any touch-pressure operation, and also includes a housing 1, a panel 2 is provided on the front of the housing 1, and a touch-pressure area 2.1 is provided on the front of the device panel 2;

[0054] The control unit includes a touch film 2.2, a circuit board 4, and a force sensor 4.1. The touch film 2.2 is arranged in conjunction with the touch and pressure area 2.1. The touch film 2.2 is arranged below the panel 2 and is arranged in conjunction with the touch and pressure area 2.1.

[0055] The force sensor 4.1 is electrically connected to the circuit board 4, and the circuit board 4 is electrically connected to the drive unit. The input end of the force sensor 4.1 is arranged in linkage with the touch and pressure area 2.1.

[0056] The panel 2 may have multiple touch-pressure areas 2.1, and the touch film 2.2 is disposed below the panel 2. Each touch-pressure area 2.1 is provided with a corresponding sensing portion on the touch film 2.2.

[0057] The rod body can also be provided corresponding to each contact pressure area 2.1, and multiple rod bodies are connected to the same bracket 6.1;

[0058] The touch film 2.2 is electrically connected to the circuit board 4, which is electrically connected to an actuator via a control circuit. When a user touches the desired touch area 2.1, the touch module responds and transmits a control command via the circuit board 4. The circuit board 4 controls the responding actuator via the control circuit to perform the corresponding action.

[0059] Circuit board 4 is disposed below panel 2. Panel 2 is provided with a transmission rod 2.3, which cooperates with the output end of force sensor 4.1. When a user touches or presses touch area 2.1 of panel 2, force sensor 4.1 detects the change in force applied during the touch and press operation, and then controls the operation of electromagnetic module 7 via the control circuit on circuit board 4.

[0060] When the user does not touch or press the touch area 2.1, the force sensor 4.1 cannot identify any force change. At this time, the electromagnetic module 7 stops working, and the contact portion 3 is out of contact with the touch area 2.1.

[0061] Compared with the existing tactile panel 2 assembly, this device can provide a clearer and more intuitive tactile feel in the touch area 2.1, and each touch area 2.1 can obtain a tactile feel when performing a touch operation, which provides a better user experience.

[0062] As an improvement of the present invention, a partition 1.1 is provided in the space inside the housing 1, and the partition 1.1 divides the housing 1 into upper and lower accommodating spaces.

[0063] The panel 2 is arranged in the upper accommodation space, the circuit board, the armature 6, and the electromagnetic module 7 are all arranged in the lower accommodation space, and the upper end of the rod body passes through the partition 1.1 and is placed below the touch and pressure area 2.1;

[0064] The partition 1.1 is provided with a stepped hole 1.14 extending vertically. A connecting post 8 is provided at the bottom of the panel 2. The connecting post 8 passes through the stepped hole 1.14 and extends below the stepped hole 1.14 at its lower end, where it is connected to a limit member 8.1. The limit member 8.1 can be a screw screwed to the lower end of the connecting post 8. The diameter of the screw can be larger than the setting of the stepped hole 1.14 to prevent the panel 2 from falling off.

[0065] An elastic buffer portion 9.1 is provided between the stopper 8.1 and the lower portion of the step hole 1.14 to allow the panel 2 to float.

[0066] A rubber ring 9 is sleeved on the lower end of the connecting column 8, and the rubber ring 9 is located between the step hole 1.14 and the peripheral side of the connecting column 8, and a buffer portion 9.1 with increased thickness is formed at the upper and lower ends of the rubber ring 9, respectively. The buffer portion 9.1 at the lower end is located between the screw and the lower end surface of the step hole 1.14, which can enable the panel 2 to be micro-suspended relative to the fixed shell 1, ensuring that relative movement (vibration) can be generated, making the hand feel obvious.

[0067] A vehicle includes a panel 2 assembly using any one of the above methods.

[0068] The housing 1 is fixed on the vehicle, and the touch area 2.1 of the panel 2 is exposed for the user to touch and operate. When the user touches and operates, the user can obtain a clear and intuitive hand feeling, and the user experience is good.
