Here, when the outer plate is made of glass material, the shielding ink layer needs to be added on the back of the outer plate because the glass is in a transparent state. The transparent infrared ink layer is arranged at the position of the back of the outer plate at the transmission opening because the transmission opening corresponding to the camera module needs to meet the palm vein infrared signal transmission requirement. Thus, the camera module can identify the palm vein, and the shielding ink layer and the transparent infrared ink layer are combined to realize palm vein unlocking.

[0034] The application will be further described below in connection with specific embodiments. It should be understood that these embodiments are only used to illustrate the application and not used to limit the scope of the application. Furthermore, it should be understood that after reading the content of the application, those skilled in the art can make various modifications or changes to the application, and these equivalent forms also fall within the scope of the appended claims.

[0035] The embodiment of the application relates to a miniaturized vein recognition module and a B-pillar trim integrating the module, as shown in Figures 1-6, comprising a camera module 200, a controller module 300, an assembly harness 400 and a micro switch module 500, the controller module 300 comprising a PCBA 3002, the PCBA 3002 being provided with a MCU component 3001, a SOC component 3004 and a RGB light 3003, the PCBA 3002 being connected with the camera module 200, the controller module 300 and the micro switch module 500, and the PCBA 3002 being further connected with a car machine through the assembly harness 400.

[0036] The miniaturized vein recognition module has modes of wake-up, recognition and execution, and the specific modes are as follows: 1. Wake-up: the vein recognition module is powered on by manually pressing the micro switch module 500; 2. Recognition: a hand is placed within 20 cm above the camera of the camera module 200, the camera collects palm vein feature information and transmits the information to the controller module 300, and the vein extraction, enhancement and feature comparison are completed through the algorithm in the SOC component 3004 in the controller module 300; 3. Execution: the MCU component 3001 transmits the vein recognition result to the car machine through the assembly harness 400, and the car machine feedback is used to unlock the car door.

[0037] The miniaturized vein recognition module has low overall power consumption in standby mode of the micro switch module 500, and in particular, the power consumption of the micro switch module 500 can meet <0.1 mA, which can meet the low power consumption demand of customers.

[0038] The camera module 200 is also provided with at least one IR light 2002, which provides light source above the camera, meets the imaging conditions in different working conditions, and greatly improves the recognition rate of the algorithm.

[0039] The final feedback result of the miniaturized vein recognition module is the light effect of the RGB lamp 3003 on the controller module 300, and the color of the lamp bead of the RGB lamp 3003 can timely remind the user, whether it is successful (green) or failed (red), which improves the user experience.

[0040] As shown in FIGS. 1-5, the application further provides a B-pillar trim panel integrated with a miniaturized vein recognition module. The B-pillar trim panel 100 includes a miniaturized vein recognition module. The camera module 200, the controller module 300 and the micro switch module 500 are fixedly installed on the back of the B-pillar trim panel 100 by screws 800. The fixation by screws 800 is only a conventional fixation method, but is not limited thereto. The controller module 300 is located below the camera module 200. The camera module 200 and the controller module 300 are connected by FPC flexible flat cable 2001. The micro switch module 500 is arranged below the controller module 300, and the two are connected by wire harness. The overall module is connected to the vehicle machine end by wire harness assembly 400.

[0041] As shown in FIG. 1, the back of the B-pillar trim panel 100 is provided with three installation stations, which correspond to the installation of the camera module 200, the controller module 300 and the micro switch module 500 respectively. Each installation station is composed of a plurality of Boss columns 1001. The hole of the Boss column 1001 is aligned with the hole of the corresponding module and is fixed by screws 800. The module is suspended and fixed by the Boss column 1001, which facilitates heat dissipation and has a certain damping effect. The installation station generally has four Boss columns 1001, which correspond to the four corners of the module. When the module is relatively small, the installation station can also have two Boss columns 1001, which correspond to the two sides of the module.

[0042] As shown in FIG. 1 and FIG. 3, in order to ensure that the electronic components of the vein module meet the IP67 requirement, a sealing cover plate 600 is installed on the back of the B-pillar trim 100, which covers each module component in the miniaturized vein identification module. As one of the sealing methods, a strip of adhesive tape 700 is arranged on the edge of the sealing cover plate 600, and the sealing cover plate 600 is wrapped around the miniaturized vein identification module by the adhesive tape 700, thereby achieving the required dustproof and waterproof level; as another sealing method, a sealing ring is arranged on the edge of the sealing cover plate 600 or the back of the B-pillar trim 100, and then the sealing cover plate 600 and the B-pillar trim 100 are fixed by fasteners.

[0043] The present application cancels the structure of the original module shell, and does not need to first install each module in the shell, and then fix the shell to the B-pillar trim 100, but directly fix each module integrated on the B-pillar trim 100, so that the miniaturized vein module can be adapted to the internal space size of the frame door trim within 13mm, which meets the space on the back of the B-pillar trim 100 provided by most OEMs. The sealing cover plate 600 is wrapped around the miniaturized vein identification module by the adhesive tape 700, thereby achieving the required dustproof and waterproof level; when problems occur later, the sealing cover plate 600 can be removed to repair and replace the vein identification module, which is relatively convenient to operate; at the same time, the microswitch is used to wake up the power-on of the vein identification module, and the microswitch power consumption is <0.1mA, which can meet the standby power consumption requirement of most OEMs for electronic components.

[0044] In the present patent, the B-pillar trim mainly includes an inner plate 101 and an outer plate 102, and the outer plate 102 can be made of two materials, plastic or glass. The selection of different materials requires special treatment of the camera module 200, which will be described step by step below.

[0045] As shown in FIG. 10, when the outer plate 102 is made of plastic material and can transmit palm vein infrared signals, the outer plate 102 and the inner plate 101 are integrally injection molded, and the camera module 200 region between the outer plate 102 and the inner plate 101 has a transmission opening 2000. Here, the outer plate 102 mainly adopts plastic material, and the plastic material needs to meet the palm vein infrared signal transmission requirement, so that the camera module 200 can identify the palm vein, thereby realizing palm vein unlocking. The color paste can also be added to the inner plate 102, which can also shield the internal devices.

[0046] As shown in FIG. 7, when the outer plate 102 is selected as a glass material, the glass can be bonded on the inner plate 101, the back surface of the outer plate 102 has an infrared transparent ink layer 900, and the inner plate 101 and the infrared transparent ink layer 900 have a corresponding camera module 200 area. Here, when the outer plate 102 is selected as a glass material, since the glass is in a transparent state, the infrared transparent ink layer 900 needs to be added to the back surface of the outer plate 102. The infrared transparent ink layer 900 can satisfy the infrared signal of the palm vein on the one hand, and on the other hand, the infrared transparent ink layer 900 can satisfy the infrared signal of the palm vein. Due to the existence of the transparent opening 2000 and the infrared transparent effect of the infrared transparent ink layer 900, the camera module 200 can identify the palm vein, thereby realizing palm vein unlocking.

[0047] As shown in FIG. 8, when the outer plate 102 is selected as a glass material in a second way, the glass can be bonded on the inner plate 101. Here, the back surface of the outer plate 102 has a shielding ink layer 1000, the back surface of the outer plate 102 at the transparent opening 2000 has an infrared transparent ink layer 900, and the inner plate 101 and the infrared transparent ink layer 900 have a corresponding camera module 200 area. Here, when the outer plate 102 is selected as a glass material, since the glass is in a transparent state, the shielding ink layer 1000 needs to be added to the back surface of the outer plate 102 for shielding. Since the camera module 200 corresponds to the transparent opening 2000, the infrared signal of the palm vein needs to be satisfied. Therefore, the infrared transparent ink layer 900 is arranged at the position of the back surface of the outer plate 102 at the transparent opening 2000. In this way, the camera module 200 can identify the palm vein, and the shielding ink layer 1000 and the infrared transparent ink layer 900 are combined to realize palm vein unlocking.

[0048] As shown in FIG. 9, when the outer plate 102 is a glass material in a third way, the glass can be bonded on the inner plate 101. The back surface of the outer plate 102 has a shielding ink layer 1000, and the inner plate 101 and the outer plate 102 have a corresponding camera module 200 area. Here, the shielding ink layer 1000 directly shields other areas of the outer plate 102, and the transparent opening 2000 is not shielded. Since the glass is in a transparent state, the camera module 200 can identify the palm vein, and palm vein unlocking is realized.

[0049] In the description of the present application, it should be understood that the orientation words such as "front, back, upper, lower, left, right", "transverse, vertical, perpendicular, horizontal" and "top, bottom" and the like indicated orientation or position relationship are generally based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, without the contrary description, these orientation words do not indicate and imply that the indicated device or element must have a particular orientation or be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the scope of protection of the present application; the orientation words "inner, outer" refer to the inner and outer relative to the contour of each component itself.

[0050] For the convenience of description, spatial relative terms such as "over", "above", "upper surface", "upper" and the like can be used herein to describe the spatial positional relationship of one device or feature with other devices or features as shown in the drawings. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the drawings. For example, if the device in the drawing is inverted, the device described as "above" or "over" other devices or structures will be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below" orientations. The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein are interpreted accordingly.

[0051] In addition, it should be noted that the use of "first", "second" and the like to define parts is only for the convenience of distinguishing the corresponding parts, and the above words have no special meaning unless otherwise stated, therefore it cannot be understood as a limitation on the scope of protection of the present application.
