Description

Technical Field

[0001] This application relates to the field of automotive parts, and in particular to a car logo light with an integrated NFC card reader. Background Technology

[0002] With the continuous development of the automotive industry, automobiles are becoming increasingly versatile, serving not only as a means of transportation but also as a vehicle for the integration of technology and design. As a crucial component of a car's exterior and branding, the role of the car logo light is becoming increasingly prominent. It not only clearly displays the car's brand logo at night or in low-light conditions, enhancing vehicle recognition and aesthetics, but also provides users with a unique visual experience.

[0003] Meanwhile, the application of NFC (Near Field Communication) technology in the automotive field is gradually becoming more widespread. NFC card readers, as a key component for realizing near field communication functions, are often used in scenarios such as vehicle unlocking, identity recognition, and information exchange. To save interior space and optimize vehicle structural design, integrating NFC card readers with car logo lights has become a trend.

[0004] However, in the existing technology, when integrating an NFC card reader into a car logo light, there is a prominent problem: in order to ensure the reading stability of the NFC card reader, its position usually needs to be above the diffuser. But in this way, the NFC card reader will block the diffuser, causing the light from the diffuser to not be able to pass through the lamp cover smoothly, which seriously affects the lighting effect and logo display function of the car logo light.

[0005] If the position of the NFC reader is changed to avoid obstruction, it will deviate from the optimal signal transmission area, reducing the accuracy and stability of card reading and failing to meet users' normal needs for NFC functionality. Therefore, how to integrate an NFC reader with a car logo light while ensuring the accuracy of the NFC reader's signal transmission and avoiding its obstruction of the diffuser's light has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] To address the aforementioned issues, this application provides a car logo light that integrates an NFC card reader.

[0007] An integrated NFC card reader for a car logo light includes a lamp cover and a base. An LED light board is fixedly installed inside the base, and a plurality of LED beads are installed on the LED light board. A diffuser is fixedly installed on the side of the LED light board near the lamp cover. The size of the diffuser covers the illumination range of the LED beads. An NFC card reader is fixedly disposed between the diffuser and the lamp cover.

[0008] By adopting the above technical solution, the NFC card reader and the car logo light are integrated into a single design. While retaining the logo light's illumination function, the NFC near-field communication function is added. This eliminates the need for an additional independent installation space for the NFC card reader and optimizes the layout of vehicle components.

[0009] Preferably, the diffuser is integrally recessed with multiple grooves in the direction of the LED lamp board to form a fixing groove. The fixing groove is positioned to avoid the illumination path of the LED lamp beads. The diffuser is fixed to the LED lamp board by screws passing through the bottom of the fixing groove.

[0010] By adopting the above technical solution, a stable connection between the diffuser and the LED light board is achieved, while avoiding the obstruction of the LED light by the fixing groove and fixing screws. This ensures that the light can pass smoothly through the diffuser and be softened, thus ensuring that the lighting effect is not affected.

[0011] Preferably, the LED light board is also connected to a power cord, which passes through the bottom shell and is connected to a power connector. The power connector is fixed by a fixing plate integrally formed on the side of the bottom shell.

[0012] By adopting the above technical solution, the power cord and power connector are stably fixed, avoiding the power connector from loosening or falling off due to vibration during vehicle operation, thus ensuring the continuity and stability of the power supply to the LED light board.

[0013] Preferably, the bottom shell has multiple threaded connecting plates integrally formed on its side. The threaded connecting plates are evenly distributed along the circumference of the bottom shell, and the threaded connecting plates have threaded holes for fixing the bottom shell to the car body.

[0014] By adopting the above technical solution, it is easy to securely install the entire car logo light on the car body. The evenly distributed threaded connecting plate makes the fixing force more balanced, improves the overall structure's vibration resistance during vehicle operation, and ensures installation stability.

[0015] Preferably, it also includes an anti-blocking structure, which is used to prevent the NFC card reader from blocking the light transmission of the diffuser.

[0016] By adopting the above technical solution, the potential light obstruction problem after integrating the NFC card reader with the logo light is specifically solved. While achieving functional integration, the lighting effect and normal use of the NFC card reading function are also taken into account.

[0017] Preferably, the anti-obstruction structure includes a notch formed on the diffuser, the size of which is adapted to the shape of the NFC reader, and the NFC reader is located within the notch area, so that the NFC reader is away from the illumination area of ​​the diffuser.

[0018] By adopting the above technical solution and physically isolating the NFC card reader, the light transmission path of the diffuser is avoided, directly eliminating the risk of obstruction and ensuring that the light from the diffuser can be emitted completely and evenly from the lampshade, thus ensuring the lighting effect of the logo light.

[0019] Preferably, the anti-blocking structure further includes a guide ramp fixed to the inner wall of the bottom shell. The guide ramp is inclined along the inner wall of the bottom shell. The bottom of the NFC card reader is connected to a guide roller. The guide roller rolls and the guide ramp. The guide ramp is used to guide the movement trajectory of the NFC card reader when it flips.

[0020] By adopting the above technical solution, a stable trajectory guide is provided for the flipping action of the NFC card reader, reducing the stuttering or offset during the flipping process, making the position adjustment of the NFC card reader smoother and more accurate, and improving the reliability of the mechanical structure.

[0021] Preferably, a connecting plate is fixedly provided on the bottom edge of the NFC card reader. The connecting plate is rotatably connected to a connecting rod via a rotating shaft. The end of the connecting rod away from the connecting plate can rotate to drive the NFC card reader to rotate around the rotating shaft.

[0022] By adopting the above technical solution, a flip transmission structure for the NFC reader was constructed. The rotation of the connecting rod drives the NFC reader to adjust its angle, providing a mechanical basis for switching the position of the NFC reader according to the vehicle status.

[0023] Preferably, the end of the connecting rod away from the connecting plate is rotatably connected to a spring via a pivot, and the other end of the spring is fixed to the bottom of the side wall of the bottom shell. The spring is used to provide a reset force when the NFC card reader is flipped.

[0024] By adopting the above technical solution, the elastic force of the spring is used to assist the NFC card reader in maintaining its posture after flipping, which reduces the continuous force on the motor and plays a buffering role during the flipping process, thereby improving the stability and service life of the structure.

[0025] Preferably, a motor is also fixedly installed on the outer wall of the bottom shell. The output shaft of the motor is fixedly connected to the connecting rod, which is used to drive the connecting rod to rotate around the axis of the motor output shaft, so that the NFC card reader flips 90° and remains perpendicular to the diffuser when the vehicle is moving, and flips upward 90° and remains parallel to and above the diffuser when the vehicle is stopped.

[0026] By adopting the above technical solution, intelligent switching of the NFC reader position is achieved: avoiding light obstruction when the vehicle is moving to ensure illumination; returning to the optimal reading position when the vehicle is stopped to ensure NFC communication stability, thus dynamically balancing the needs of the two functions.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. It achieves efficient integration of NFC card reader and car logo light without taking up extra vehicle space, simplifies component layout, and retains the integrity of both functions, enhancing the vehicle's technological feel and ease of use;

[0029] 2. The two anti-obstruction structures completely solve the problem of NFC card readers blocking light by static isolation and dynamic angle adjustment, respectively. This ensures both the uniformity and softness of the logo light illumination, as well as the signal stability and card reading accuracy of the NFC card reader during use.

[0030] 3. The design of the fixed groove, threaded connection plate, and power connector fixing plate takes into account both ease of installation and structural stability, and can adapt to complex working conditions such as vibration and temperature changes during vehicle operation, thereby improving the reliability and service life of the product.

Detailed Implementation

[0039] The present application will be further described in detail below with reference to the accompanying drawings.

[0040] In the description of the invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the invention.

[0041] Example 1

[0042] This application discloses a car logo light integrating an NFC card reader, see reference... Figure 1 and Figure 2This invention discloses a car logo light integrating an NFC card reader. Its overall structure includes a lampshade 1 and a base 2, which cooperate to form a relatively enclosed space to protect the internal components. An LED light board 31 is fixedly installed inside the base 2, providing the light source for the entire logo light. Several LED beads 32 are installed on the LED light board 31, evenly distributed or arranged according to the shape of the car logo to ensure uniform illumination and highlight the logo. A diffuser 42 is fixedly installed on the side of the LED light board 31 near the lampshade 1. The diffuser 42 covers the illumination range of the LED beads 32, softening the relatively glaring light emitted by the LED beads 32, making the light emitted from the lampshade 1 softer and more uniform. An NFC card reader 41 is fixedly disposed between the diffuser 42 and the lampshade 1, and is connected to the LED light board 31 via wiring, realizing the integration of NFC card reading function with the car logo light. Regarding the fixing method of the diffuser plate 42, multiple grooves are integrally recessed on the diffuser plate 42 towards the LED light panel 31 to form a fixing groove 421. The position of the fixing groove 421 is carefully designed to avoid the illumination path of the LED beads 32, so as not to affect the normal emission of light from the LED beads 32. By passing screws through the bottom of the fixing groove 421, the diffuser plate 42 can be firmly fixed to the LED light panel 31, ensuring the stability of the diffuser plate 42 during vehicle movement, etc. A power cord 33 is also connected to the LED light panel 31. The power cord 33 passes through the bottom shell 2 and is connected to a power connector 22 to provide power support to the LED light panel 31. The power connector 22 is fixed by a fixing plate 21 integrally formed on the side of the bottom shell 2, ensuring that the power connector 22 will not loosen or fall off during use, ensuring the stability of the power supply. To secure the car logo light to the car body, multiple threaded connecting plates 23 are integrally formed on the side of the base shell 2. The threaded connecting plates 23 are evenly distributed around the circumference of the base shell 2, and threaded holes 24 are formed on the threaded connecting plates 23. During installation, bolts are passed through the threaded holes 24 to connect with the car body, thereby firmly fixing the base shell 2 to the car body.

[0043] In addition, the car logo light with integrated NFC card reader 41 also includes an anti-obstruction structure, which is used to prevent the NFC card reader 41 from blocking the light transmission of the diffuser 42. The two anti-obstruction structures are described in detail below.

[0044] Reference Figure 3 and Figure 4The first type of anti-obstruction structure includes a notch 50 formed in the diffuser 42, the size of which is adapted to the shape of the NFC reader 41. By placing the NFC reader 41 within the notch 50, the NFC reader 41 is kept away from the illumination area of ​​the diffuser 42, thereby effectively preventing the NFC reader 41 from blocking the light from the diffuser 42 and ensuring that the light can pass smoothly through the lampshade 1.

[0045] The implementation principle of Example 1 is as follows: The bottom shell 2 and the lamp cover 1 cooperate to form a closed space. An LED light board 31 is fixed inside the bottom shell 2, and the LED beads 32 on the LED light board 31 provide a light source for the logo light. The fixing groove 421 formed by the recess of the diffuser plate 42 towards the LED light board 31 avoids the illumination path of the LED beads 32, and the size of the diffuser plate 42 covers the illumination range of the LED beads 32, which can effectively soften the light.

[0046] An NFC reader 41 is fixed between a diffuser 42 and a lampshade 1. The diffuser 42 has a notch 50 that matches the shape of the NFC reader 41. The NFC reader 41 is embedded within this notch 50, keeping it away from the light-illuminating area of ​​the diffuser 42. Because the NFC reader 41 is located within the notch 50 of the diffuser 42, and the notch 50 avoids the light path, the NFC reader 41 does not block the light transmission of the diffuser 42. This ensures that the light from the LED beads 32, softened by the diffuser 42, is smoothly emitted from the lampshade 1, while also positioning the NFC reader 41 appropriately to guarantee reading stability.

[0047] Example 2

[0048] Reference Figure 5 , Figure 6 and Figure 7 Since the NFC reader 41 is not used while the car is in motion, according to this rule, the second anti-obstruction structure, in addition to avoiding light blockage, can also adjust the position of the NFC reader 41 according to the vehicle status to ensure its signal transmission accuracy. This structure includes a guide ramp 61 fixed to the inner wall of the bottom shell 2, which is inclined along the inner wall of the bottom shell 2. The wire connecting the NFC reader 41 and the LED light panel 31 provides a certain margin for the movement of the NFC reader 41. A guide roller 62 is connected to the bottom of the NFC reader 41, and the guide roller 62 rolls and overlaps with the guide ramp 61. The guide ramp 61 guides the movement trajectory of the NFC reader 41 during its flipping, making the flipping process of the NFC reader 41 more stable and smooth.

[0049] An NFC card reader 41 has a connecting plate fixedly mounted on its bottom edge. The connecting plate is rotatably connected to a connecting rod 63 via a pivot. The end of the connecting rod 63 away from the connecting plate is rotatable, causing the NFC card reader 41 to flip around the pivot. The end of the connecting rod 63 away from the connecting plate is rotatably connected to a spring via the pivot. The other end of the spring is fixed to the bottom of the side wall of the bottom shell 2. The spring provides a restoring force when the NFC card reader 41 flips, assisting the NFC card reader 41 in completing the flipping action and maintaining a stable state.

[0050] A motor 64 is also fixedly installed on the outer wall of the bottom shell 2. The output shaft of the motor 64 is fixedly connected to the connecting rod 63, and the output shaft of the motor 64 is connected to the connecting rod 63 near the spring and to the end of the connecting rod 63. The motor 64 is used to drive the connecting rod 63 to rotate around the axis of the output shaft of the motor 64. When the vehicle is moving, the motor 64 drives the connecting rod 63 to rotate, causing the NFC card reader 41 to rotate 90°. At this time, the NFC card reader 41 is perpendicular to the diffuser 42 and will not block the light of the diffuser 42, ensuring the normal illumination of the logo light. When the vehicle is stopped, the NFC card reader 41 is used. The motor 64 drives the connecting rod 63 to rotate in the opposite direction, flipping the NFC card reader 41 upward by 90°, so that the NFC card reader 41 is placed above the diffuser 42 and parallel to the diffuser 42. This position ensures the accuracy of the signal transmission of the NFC card reader 41 and ensures the normal use of the NFC card reading function. During the entire flipping process, the guide roller 62 rolls on the guide ramp 61. Guided by the guide ramp 61, the NFC card reader 41 flips smoothly along a predetermined trajectory. At the same time, the spring deforms according to the flipping state of the NFC card reader 41, providing corresponding elastic force to help maintain the stability of the NFC card reader 41 in different states.

[0051] The implementation principle of Example 2 is as follows: When the vehicle is in motion, it provides an anti-obstruction effect. Motor 64 starts, and its output shaft drives connecting rod 63 to rotate around its own axis. The rotation of connecting rod 63 causes the connecting plate and NFC reader 41 to flip around the axis. At this time, guide roller 62 rolls along guide ramp 61, which guides the flipping trajectory, ensuring smooth movement. Finally, the NFC reader 41 flips 90°, maintaining a perpendicular position to the diffuser 42 and moving away from the light-irradiated area of ​​the diffuser 42. Simultaneously, the spring generates a restoring force due to deformation, assisting the NFC reader 41 in maintaining its vertical posture. In this state, the NFC reader 41 does not obstruct the light transmission of the diffuser 42, and no notch 50 is needed on the diffuser 42. This ensures the illumination effect of the logo light.

[0052] When the vehicle is stationary, the NFC reader 41 facilitates card reading. Motor 64 drives linkage 63 to rotate in the reverse direction, causing linkage 63 to flip the NFC reader 41 in the opposite direction. Guide roller 62 rolls in the opposite direction along guide ramp 61, and springs gradually release their force to assist in resetting. Finally, the NFC reader 41 flips upwards by 90°, remaining parallel to and above the diffuser 42, returning to the optimal signal transmission area. In this state, the NFC reader 41 is in a stable position, ensuring accurate and stable card reading during near-field communication.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
