Description

Technical Field

[0001] This utility model belongs to the field of automotive trim panels, specifically relating to a touch-sensitive structure for automotive metal interior parts. Background Technology

[0002] The automotive interior system is a crucial component of the car body, and its design workload accounts for over 60% of the overall vehicle styling design workload, far exceeding that of the exterior, making it one of the most important parts of the vehicle. With technological advancements and the increasing demands for multi-functionality in vehicles, interior components are beginning to incorporate touch controls to trigger certain functions. However, currently, for the sake of overall vehicle structural integrity, most automotive interior systems are constructed from metal and plastic materials to meet specific rigidity requirements.

[0003] Current touchscreen technology is based on glass substrates. Therefore, in order to meet the touch requirements, the industry can only use pressure-sensitive touch and double-layer touch film. However, both of these technologies require the metal panel to undergo micro-deformation during use, and the amount of deformation is detected for control. Although this method can achieve certain technical effects, in order to produce micro-deformation, the metal panel needs to be made very thin, which will greatly reduce local stress and also reduce the lifespan of the panel. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A touch control structure for automotive metal interior trim, comprising, from top to bottom, a metal layer, a structural support layer, and a PCB layer;

[0006] The metal layer has perforated holes engraved with touch patterns, and the structural support layer has perforated holes to prevent the touch patterns from being exposed to air. The metal layer is fixedly connected to the structural support layer, and the structural support layer is used for installation and connection with other structural components.

[0007] The PCB layer includes a PCB board and a transmitter and a receiver mounted on the PCB board; the PCB layer is fixedly connected to the structural support layer.

[0008] Furthermore, the metal layer is aluminum, and the metal layer undergoes oxidation, wire drawing, and printing processes.

[0009] Furthermore, after the metal layer is stamped, insert plastic is injected to form a whole.

[0010] Furthermore, the transmitting end and the receiving end are infrared modules, ultrasonic modules, millimeter-wave modules, and laser modules.

[0011] Furthermore, the functional module is electrically connected to the transmitter and receiver of the infrared module via a PCB board. The functional module is used to perform specific functions. When the receiver of the infrared module receives a feedback signal, the functional module begins to execute.

[0012] The beneficial effects of this utility model are:

[0013] 1. The transmitter of this utility model emits an infrared beam in real time. The infrared beam passes through the hollow hole of the touch pattern and radiates outward. When a finger touches the touch pattern, the infrared beam is reflected back by the finger, passes through the hollow hole, and is received by the infrared receiver. At this time, an electrical signal is generated and fed back to the PCB board. The PCB board can execute the relevant function control by detecting the electrical signal. The touch structure of this utility model has accurate feedback, simple structure, avoids deformation of the metal panel surface, and improves the service life of the panel.

[0014] 2. This utility model utilizes infrared detection touch to achieve control, reducing the use of a large number of physical buttons and solving production costs.

[0015] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention. Specific Implementation

[0022] like Figures 1 to 3The touch structure of a metal interior trim piece for automobiles shown consists of, from top to bottom, a metal layer 1, a structural support layer 2, and a PCB layer 3.

[0023] The metal layer 1 has perforated holes 11 engraved with touch patterns, and the structural support layer 2 has perforated holes 21 for preventing the touch patterns from being exposed. The metal layer and the structural support layer 2 are fixedly connected, and the structural support layer 2 is used for installation and connection with other structural components. Specifically, the metal layer 1 is preferably aluminum, and the metal layer 1 needs to undergo oxidation, wire drawing, and printing processes. These steps not only form exquisite patterns on the aluminum surface but also protect the surface, increasing its wear resistance and corrosion resistance. Specifically, after the metal layer 1 is stamped, insert plastic injection is performed to form a whole. After injection molding, a touch pattern is laser-engraved at the corresponding position on the surface. The pattern position needs to be laser-engraved through the aluminum plate, that is, the perforated holes 11 of the touch pattern are engraved.

[0024] The PCB layer 3 includes a PCB board 31 and a transmitter 32 and a receiver 33 mounted on the PCB board 31; the PCB layer is fixedly connected to the structural support layer 2. Specifically, the transmitter 32 and receiver 33 are infrared modules, ultrasonic modules, millimeter-wave modules, and laser modules, preferably infrared modules. The principle of infrared technology is that an infrared beam is emitted by an infrared transmitter tube. When the infrared beam is blocked, it is reflected back to the infrared receiver tube; the infrared receiver tube detects the reflected infrared beam and generates an electrical signal to realize the switching control function. Specifically, the PCB board 31 is also electrically connected to a functional module. The functional module is electrically connected to the infrared transmitter and the infrared receiver 33 through the PCB board. The functional module is used to perform a specific function. When the infrared receiver 33 receives a feedback signal, the functional module starts to execute. In this embodiment, the functional modules selected are a temperature sensor 34 and a lamp group 35. Of course, this is only an example selection in this embodiment. Figure 2 When the transmitter 32 emits an infrared beam, when a finger touches the touch pattern, the infrared beam is reflected back by the finger and received by the infrared receiver 33, which generates an electrical signal that is fed back to the PCB board. After the PCB board detects the electrical signal, it increases the voltage of the lamp group 35, and the lamp group emits light. At the same time, it retrieves the electrical signal from the temperature sensor and outputs the real-time temperature inside the vehicle.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
