[0002] With the rapid development of the automotive industry, the automobile is no longer just a means of transportation or a single-purpose vehicle for getting around. It has gradually evolved into a movable "home" full of comfort, simplicity, a sense of technology, and intelligence. Under this development background, the vehicle cockpit system has undergone great changes, and at the same time, in-vehicle functions have been greatly improved, making the vehicle more intelligent and full of a sense of technology. In order to create a warm, simple, and intelligent cockpit environment, the cockpit control system is gradually evolving from traditional physical switch buttons into touch intelligent surfaces. Vehicle passengers can control the vehicle through the touch intelligent surface, and functions such as seat adjustment, rearview mirror adjustment, door opening and closing, and lighting adjustment can be realized.

[0003] At present, most of the function controls of existing automobiles are still carried out in the form of physical buttons or physical switches. This traditional control method has the following disadvantages:

[0004] (1) For each function control, a switch button needs to be designed, and at the same time, its separate electronic control module and assembly structure need to be designed, increasing the design cost and process complexity;

[0005] (2) The overall size of the switch button assembly is large and heavy, gradually not meeting the requirements of vehicle lightweighting, and the large size will also limit the overall vehicle design structure;

[0006] (3) Most physical buttons or switches are flat structures and are difficult to be designed into 3D stereoscopic shapes;

[0007] (4) When a large number of physical buttons or switches are arranged together, the subjective feeling of the cockpit for the driver and passengers will be relatively messy. Summary of the Utility Model

[0008] The utility model conducts research and development in the face of the disadvantages existing in the current automobile function control method, and designs a multifunctional touch intelligent surface. The multifunctional touch intelligent surface can integrate multiple functions for control, can reduce the overall weight, reduce the assembly space, reduce the process complexity, and at the same time can also enhance the overall sense of technology of the cockpit, etc., solving the problems existing in the traditional control method.

[0009] To achieve the above object, the utility model provides a multifunctional touch intelligent surface, including an IME intelligent surface module. The IME intelligent surface module includes a touch layer, a pattern layer, a touch capacitance layer, a flexible circuit layer, an injection molding layer, a buzzer, a PCB control module, a vibration motor, a pressure sensor and an FPC cable. The touch layer is arranged on the front of the diaphragm, and the back of the diaphragm is successively provided with a pattern layer, a touch capacitance layer, a flexible circuit layer and an injection molding layer. The back of the injection molding layer is provided with a buzzer, a PCB control module, a vibration motor and a pressure sensor. One end of the FPC cable is connected to the flexible circuit layer, and the other end of the FPC cable, the buzzer, the vibration motor and the pressure sensor are connected to the PCB control module.

[0010] As a further optimization, a varnish layer is provided on the touch layer.

[0011] As a further optimization, a color ink layer is provided on the pattern layer.

[0012] As a further optimization, a transparent conductive ink layer is provided on the touch capacitance layer.

[0013] As a further optimization, a conductive silver paste layer is provided on the flexible circuit layer, and electronic components are provided through the SMT patching process.

[0014] As a further optimization, this application further includes a C-shaped decorative strip and an atmosphere lamp board module. After the IME intelligent surface module is connected to the C-shaped decorative strip, it is then connected to the atmosphere lamp board module.

[0015] Advantages and beneficial effects of the utility model

[0016] 1. The utility model integrates multiple switch buttons onto one touch panel. Compared with the traditional control method, the number of switch buttons is reduced, making the overall weight of the vehicle lighter, reducing the assembly process steps of the switch buttons, lowering the production cost of parts and the labor assembly cost, and reducing the electronic control module and the structure assembled with it, thus reducing the circuit design cycle.

[0017] 2. The utility model solves the drawback of the traditional switch button being relatively thick and heavy through the integrated plastic and electricity design, integrates the circuit in the plastic part, reduces the PCB board, the light homogenizing board and the back shell structure, greatly reduces the thickness of the overall size of the switch button assembly, and saves the assembly space.

[0018] 3. Since the main body of the IME intelligent surface module of the utility model is a diaphragm, and the diaphragm has good flexibility and stretchability, the IME intelligent surface can achieve complex 3D shapes, solving the pain point of the physical button or switch being a planar design structure.

[0019] 4. The integrated 3D modeling design of the IME intelligent surface module in the present utility model greatly enhances the simplicity of the cockpit.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will describe in detail the specific embodiments of the present utility model with reference to the drawings. It should be noted that in the description of the present utility model, the orientation or positional relationships indicated by terms such as "front", "back", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0026] Such as Figure 1As shown in the figure, a multifunctional touch intelligent surface includes an IME intelligent surface module 1. The IME intelligent surface module 1 includes a touch layer 1-1, a pattern layer 1-2, a touch capacitive layer 1-3, a flexible circuit layer 1-4, an injection layer 1-5, a buzzer 1-6, a PCB control module 1-7, a vibration motor 1-8, a pressure sensor 1-9, and an FPC cable 1-10. A varnish layer is printed on the touch layer 1-1. After drying and curing, the varnish layer makes the touch layer 1-1 have a more three-dimensional touch feeling and also has the functions of protection and anti-corrosion. The touch layer 1-1 is printed on the front side of the diaphragm. On the back side of the diaphragm, the pattern layer 1-2, the touch capacitive layer 1-3, and the flexible circuit layer 1-4 are printed in sequence. A color ink layer is printed on the pattern layer 1-2. The color ink layer can make the surface of the pattern layer 1-2 have decorative patterns and graphics representing various function keys. A transparent conductive ink layer is provided on the touch capacitive layer 1-3. The transparent conductive ink layer has the functions of conducting electricity and preventing static electricity. A conductive silver paste layer is provided on the flexible circuit layer 1-4. The conductive silver paste layer has the functions of conducting current and removing accumulated static charges. After the touch layer 1-1, the pattern layer 1-2, the touch capacitive layer 1-3, and the flexible circuit layer 1-4 are printed, a drying process is carried out to dry and cure the varnish layer on the touch layer 1-1, the color ink layer on the pattern layer 1-2, the transparent conductive ink layer on the touch capacitive layer 1-3, and the conductive silver paste layer on the flexible circuit layer 1-4. After drying and curing, electronic components such as lamp beads and resistors required are attached to the flexible circuit layer 1-4 through the SMT patching process. After SMT patching, the diaphragm is formed into a 3D design shape through a high-pressure forming process. After forming, the waste materials around the diaphragm are cut off to obtain a complete diaphragm with a 3D design shape. The next step is the injection process. The injection plastic is injected on the back side of the diaphragm to form an injection layer 1-5 with an installation structure, and thus a plastic part that can be assembled is obtained.

[0027] The buzzer 1-6, the PCB control module 1-7, the vibration motor 1-8, and the pressure sensor 1-9 are arranged on the back side of the injection layer 1-5 through the installation structure. One end of the FPC cable 1-10 is connected to the flexible circuit layer 1-4 in the plastic part. The other end of the FPC cable 1-10, the buzzer 1-6, the vibration motor 1-8, and the pressure sensor 1-9 are connected to the PCB control module 1-7, thereby obtaining the IME intelligent surface module 1. The buzzer 1-6 can emit a touch prompt sound, and the vibration motor 1-8 can provide a vibration feedback after touch. The pressure sensor 1-9 can set a preset value. If the pressure detected by the pressure sensor 1-9 is within the preset value, the corresponding function is normally turned on. If the pressure detected by the pressure sensor 1-9 is outside the preset value, the corresponding function will not start, thereby preventing the driver and passengers from accidentally touching and turning on the corresponding function.

[0028] Through the integrated design of plastic and electricity, the circuit of the utility model is integrated into the plastic part, enabling multiple switch buttons to be integrated into one touch panel. Compared with the traditional control method, the number of parts is reduced, the overall weight of the vehicle can be reduced, the assembly process steps of the switch buttons are also reduced, and the production cost of parts and the labor assembly cost are lowered. At the same time, the main body of the IME intelligent surface module 1 of the present application is a diaphragm, which has good flexibility and stretchability. Therefore, the IME intelligent surface module 1 can achieve complex 3D shapes.

[0029] As Figure 2 and Figure 3 shown, a multifunctional touch intelligent surface includes an IME intelligent surface module 1, a C-shaped decorative strip 2, and an ambient light panel module 3. After the IME intelligent surface module 1 is inserted into the C-shaped decorative strip 2 and then inserted into the ambient light panel module 3, the three are connected by ultrasonic welding process to form an intermediate insertion assembly, and finally the intermediate insertion assembly is connected to the car door panel. Through the integrated design of plastic and electricity of the IME intelligent surface module 1, the simplicity of the cockpit is greatly improved. Combined with the C-shaped decorative strip 2 and the ambient light panel module 3, the user experience of the cockpit is greatly enhanced.

[0030] Working principle

[0031] When a person's hand touches the touch layer 1-1, the charge of the human body and the charge of the touch capacitance layer 1-3 are transferred to form a circuit. The electrical signal is transmitted to the PCB control module 1-7 through the conductive silver paste in the flexible circuit layer 1-4 and the FPC cable 1-10. The PCB control module 1-7 reads the relevant information and compares it with the preset value set on the pressure sensor 1-9. If the touch pressure value is within the preset value, the relevant function will be triggered. At the same time, the PCB control module 1-7 will control the vibration motor 1-8 and the buzzer 1-6 to make the vibration motor 1-8 provide vibration feedback after touching, and the buzzer 1-6 provide a key prompt sound. If the touch pressure value is not within the preset value, the corresponding function cannot be activated.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present utility model, and are not intended to limit them; although the embodiments of the present utility model have been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
