[0003] Current patent: CN117437666A discloses a vein recognition module and a B-pillar trim panel integrating the module. In this vein recognition module, each module component is fixedly installed inside the housing. The housing is composed of an upper housing cover and a lower housing cover. Then, when the vein recognition module is installed, the housing is fixed to the B-pillar trim panel. This makes the entire vein recognition module relatively large in volume, and the required internal space size of the trim panel is also relatively large, unable to meet the requirements of miniaturization of B-pillar trim panels for framed and frameless doors. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a miniaturized vein recognition module and a B-pillar trim panel integrating the module, which cancels the original structure of the module housing. In this way, the required internal space size of the trim panel is also relatively small, and it can well meet the requirements of miniaturization of B-pillar trim panels for framed and frameless doors.

[0005] The technical solution adopted by the utility model to solve its technical problems is: to provide a miniaturized vein recognition module, including a camera module, a controller module, and a microswitch module.

Detailed Embodiment

[0024] The following further elaborates the present utility model in combination with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0025] Embodiments of the present utility model relate to a miniaturized vein recognition module and a B-pillar trim panel integrated with this module. As Figures 1-6 shown, it includes a camera module 200, a controller module 300, a total assembly wire harness 400, and a microswitch module 500. The controller module 300 includes a PCBA 3002, and an MCU component 3001, an SOC component 3004, and an RGB light 3003 are integrally arranged on the PCBA 3002. The PCBA 3002 is respectively connected to the camera module 200, the controller module 300, and the microswitch module 500, and the PCBA 3002 is also connected to the vehicle head unit through the total assembly wire harness 400.

[0026] The miniaturized vein recognition module has modes such as wake-up, recognition, and execution, which are specifically as follows: First, wake-up: Press the microswitch module 500 manually to wake up the power-on of the vein recognition module; Second, recognition: The hand needs to be placed within 20 cm above the camera of the camera module 200. The camera collects the palm vein feature information and transmits it to the controller module 300. The algorithm in the SOC component 3004 inside the controller module 300 completes vein extraction, enhancement, and feature comparison; Third, execution: The MCU component 3001 transmits the vein recognition result to the vehicle head unit through the total assembly wire harness 400, and the vehicle head unit central control feedback unlocks and locks the vehicle door.

[0027] The miniaturized vein recognition module uses the microswitch module 500 for standby with low overall power consumption. In particular, the power consumption of the microswitch module 500 can meet <0.1 mA, which can meet the low-power requirements of customers.

[0028] At least one IR fill light 2002 is also integrally arranged on the camera module 200. The IR fill light 2002 provides a strong light source above the camera to meet the imaging conditions in different working conditions, which can greatly improve the recognition rate of the algorithm.

[0029] The final feedback result of the miniaturized vein recognition module is the light effect of the RGB light 3003 on the controller module 300. The bead color of the RGB light 3003 can timely remind the user, whether it is successful (green) or failed (red), which overall improves the user experience.

[0030] As Figures 1-5As shown in the figure, the present utility model 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 microswitch module 500 are all fixedly installed on the back surface of the B-pillar trim panel 100 by screws 800. Fixing by screws 800 is just a conventional fixing method, but not limited to this. The controller module 300 is located below the camera module 200, and the camera module 200 and the controller module 300 interact with each other through an FPC flexible cable 2001. The microswitch module 500 is arranged below the controller module 300, and the two interact through a wire harness. The overall module is connected to the vehicle head unit through a wire harness assembly 400.

[0031] Referring to Figure 1 As shown in the figure, three installation positions are provided on the back surface of the B-pillar trim panel 100, and the three installation positions respectively correspond to the installation of the camera module 200, the controller module 300, and the microswitch module 500. Each installation position is composed of several Boss posts 1001. The hole positions of the Boss posts 1001 are aligned with the hole positions of the corresponding module and are fixedly connected by screws 800; the modules are suspended and fixed by the Boss posts 1001, which is convenient for module heat dissipation and has a certain shock absorption effect; generally, there are four Boss posts 1001 in a conventional installation position, and the four Boss posts 1001 correspond to the four corners of the module; when the module is relatively small, the installation position can also have two Boss posts 1001, and the two Boss posts 1001 correspond to both sides of the module.

[0032] As Figure 1 and Figure 3 As shown in the figure, in order to ensure that the electronic components of the vein module meet the IP67 requirements, a sealing cover plate 600 is installed on the back surface of the B-pillar trim panel 100, and the sealing cover plate 600 covers the module components in the miniaturized vein recognition module. As one of the sealing methods, a tape 700 is arranged on the edge of the sealing cover plate 600, and the sealing cover plate 600 is wrapped by the tape 700 to bond and seal the miniaturized vein recognition module, so as to achieve the required dust and water protection level; as another sealing method, a sealing ring is arranged on the edge of the sealing cover plate 600 or the back surface of the B-pillar trim panel 100, and then the sealing cover plate 600 and the B-pillar trim panel 100 are fixed by fasteners.

[0033] The present utility model cancels the structure of the original module housing. It is not necessary to first install each module inside the housing and then fix the housing to the B-pillar trim 100. Instead, each module is directly fixed and integrated on the B-pillar trim 100. In this way, this miniaturized venous module can adapt to the internal space size of the framed door trim within 13 mm, meeting the space requirements of the back of the B-pillar trim 100 for most vehicle manufacturers. The miniaturized venous recognition module is wrapped by a sealing cover plate 600 bonded with a tape 700 to achieve the required dust and waterproof level. When a problem occurs later, as long as the sealing cover plate 600 is removed, the venous recognition module can be repaired and replaced, which is relatively convenient to operate. At the same time, the micro switch is used to wake up the venous recognition module to power on. The power consumption of the micro switch is <0.1 mA, which can meet the standby power consumption requirements of most vehicle manufacturers for electronic components.

[0034] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or component referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0035] For the convenience of description, spatial relative terms such as "above...", "above...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the drawings for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "beneath other devices or structures" afterwards. Thus, the exemplary term "above..." can include two orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations for the spatial relative descriptions used here are made.

[0036] In addition, it should be noted that using words such as "first", "second" to limit components is only for the convenience of distinguishing the corresponding components. Without additional declaration, the above words have no special meaning. Therefore, it cannot be understood as a limitation on the protection scope of the present utility model.

[0037] The above has introduced in detail a miniaturized vein recognition module provided by the present application and a B-pillar trim panel integrating the module. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
