Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, and in particular to a light-emitting module, an automobile light-emitting pedal and an automobile. Background Art

[0002] A car pedal refers to a car accessory installed at the door sill of a car to facilitate the driver and passengers to get on and off the car. At present, in order to facilitate the driver and passengers to get on and off the car at night or in low light, as well as to increase the aesthetics of the car, prompts are usually set on the car pedals.

[0003] For example, a Chinese invention patent (CN104554032A) discloses a light-emitting car pedal, which adds an LED light strip to the substrate to make it light-emitting, thereby providing a safety mark for the driver and passengers. However, the long-term lighting of the above-mentioned LED light strip will reduce its role as a safety warning and cause visual interference to the driver or passengers. Based on this, some manufacturers have gradually tried to use smarter lighting methods, such as lighting up the car pedal by sensing the current lighting conditions, or lighting up the car pedal by detecting whether it is stepped on by the driver or passenger through a resistive pressure sensor. However, in actual use, the method of sensing external light is prone to cause the car pedal to not respond when opening and closing the door due to the instability of the sensing switch; and the pressure sensor has a limited tolerance to pressure, and a certain gravity threshold must be reached before the car's light-emitting pedal can be lit, and it is difficult to withstand high-pressure shocks, and the driver or passenger may easily cause damage to the car's light-emitting pedal when jumping. Summary of the invention

[0004] The present invention provides a light-emitting module, a car light-emitting pedal and a car, so as to solve the problem that the car light-emitting pedal in the prior art is difficult to meet the requirements of individualization and stability.

[0005] To solve the above technical problems, in a first aspect, the technical solution adopted by the present invention is to provide a light-emitting module, which includes: a light-transmitting panel, a shell, an electronic component group, a plurality of piezoelectric sensors and a light source.

[0006] The light-transmitting panel is arranged to form a plurality of light-emitting areas at intervals along a first direction; the shell and the light-transmitting panel are enclosed to form a light-emitting chamber; the electronic control group is located in the light-emitting chamber; the piezoelectric sensor corresponds to the light-emitting area one by one, wherein the piezoelectric sensor is located in the light-emitting chamber and is electrically connected to the electronic control group, and the piezoelectric sensor is configured to sense the deformation of the shell or the light-transmitting panel and output a piezoelectric signal to the electronic control group; the light source is located in the light-emitting chamber and is electrically connected to the electronic control group.

[0007] The technical solution provided by the present invention has the following beneficial effects compared with the prior art: By setting the light-transmitting panel into multiple light-emitting areas, the light-emitting areas correspond one-to-one with the piezoelectric sensors, so as to realize independent light emission of the light-emitting areas. Among them, the light-emitting chamber composed of the light-transmitting panel and the shell can accommodate a variety of electronic components (including piezoelectric sensors, electronic group controls and light sources, etc.), so that when the user applies pressure to the light-transmitting panel (for example, the user steps on it), the piezoelectric sensor located in the light-emitting chamber can detect the deformation of the shell and the light-transmitting panel and feel the current pressure position, so as to output the corresponding piezoelectric signal to the electronic group control, so that the electronic group control can drive the corresponding light source to light up according to the piezoelectric signal, realizing a personalized interactive lighting solution.

[0008] In addition, piezoelectric sensors can detect extremely small structural deformations and emit piezoelectric signals. Compared with conventional resistive pressure sensors, the housing can be made of stronger materials, so when it is used in car light-emitting pedals, it can enhance the durability of the car light-emitting pedals. In addition, the above-mentioned interactive lighting scheme does not emit light when not under pressure, which can reduce visual interference to passengers or drivers. When under pressure, its light-emitting mode can also be customized to the pattern and color of the light source, thereby improving the aesthetics of the car light-emitting pedals.

[0009] In some embodiments, the electronic group control is used to receive the piezoelectric signal of the piezoelectric sensor and output a corresponding PWM signal to the light source according to the piezoelectric signal; wherein the light source includes a plurality of LED lights arranged at intervals along the first direction, and the LED lights can display corresponding brightness according to the PWM signal.

[0010] Using the above technical solution, PWM (Pulse Width Modulation) is pulse width modulation, which controls the average value of the output voltage by adjusting the width of the pulse, and then controls the brightness of the corresponding LED lamp. Among them, the electronic group control uses PWM signals to accurately adjust the brightness of the LED lamp, which can achieve more diverse lighting modes. For example, the electronic group control adjusts the brightness of the LED lamp so that the brightness of the LED lamp can change according to the change of the pressure value, thereby realizing a more personalized pressure sensing and visual feedback linkage lighting mode.

[0011] Furthermore, the light-emitting area includes a sensing area and a lighting area, the sensing area is a real-time pressure trigger area that can be sensed by the piezoelectric sensor, and the lighting area is a stepless dimming area where the electronic group control can continuously adjust the brightness of the light source according to the real-time pressure intensity of the sensing area.

[0012] With the above technical solution, stepless dimming refers to the technology of continuously and steplessly adjusting the brightness and color temperature of light. The above electronic group control uses PWM signals to accurately adjust the LED light, realizing stepless adjustment of the LED light brightness from 0% to 100%, thereby achieving a smoother and more comfortable dimming effect for the luminous area.

[0016] By adopting the above technical solution, the first convex part and the second convex part, the first concave part and the second concave part are respectively engaged to ensure the stability and sealing of the connection between the light-transmitting panel and the shell. Among them, bonding the piezoelectric sensor along the bottom surface of the shell can effectively detect the extremely small deformation of the shell, and compared with bonding the piezoelectric sensor to the light-transmitting panel, it can avoid interfering with the lighting effect of the light source.

[0017] In some embodiments, the electronic group control includes electronic components and a PCB board, the electronic components are arranged at intervals along the first direction and correspond to the light-emitting areas and the piezoelectric sensors one by one; the PCB board extends along the first direction and is located between the light source and the piezoelectric sensor along the third direction. With the above technical solution, precise control of each light-emitting area is achieved through the layout of the electronic components and the PAC board.

[0018] In some embodiments, the shell further includes a fixing bracket, which is located in the light-emitting chamber, wherein the fixing bracket includes a plurality of bolts spaced apart along the first direction, and the bolts penetrate the PCB board along a third direction and abut against the bottom surface of the shell.

[0019] By adopting the above technical solution, a fixing bracket is provided to further enhance the structural strength of the light emitting module so that it can withstand greater pressure.

[0020] In some embodiments, the light emitting chamber further comprises a light-homogenizing film, which is attached to the inner side of the light-transmitting panel along the third direction. With the above technical solution, the light-homogenizing film can make the light emitted by the light source softer and more uniform, thereby improving the display effect of the light-transmitting panel.

[0021] In a second aspect, the present application further provides an automotive light pedal, comprising an integrated board and an MCU module. The integrated board is provided with a plurality of mounting grooves spaced along a second direction, wherein the above-mentioned light-emitting modules are embedded in the mounting grooves, wherein the light-emitting areas of the plurality of light-emitting modules can be combined into a light panel area; and the MCU module is communicatively connected with the electronic group control and the piezoelectric sensor of the light-emitting module.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] For the convenience of subsequent description, before describing the specific structure of the light emitting module, the automobile light emitting pedal and the automobile, the present application first describes the light emitting module, the automobile light emitting pedal and the automobile. Figure 1 and Figure 2A first direction (X), a second direction (Y), and a third direction (Z) are defined. The first direction is the length direction of the light-emitting module when it is normally placed, such as the X direction; the second direction is the width direction of the light-emitting module when it is normally placed, such as the Y direction; and the third direction is the height direction of the light-emitting module when it is normally placed, such as the Z direction. In this application, the first direction (X), the second direction (Y), and the third direction (Z) are perpendicular to each other.

[0029] It can be understood that the mutual perpendicularity in the present application is not absolute perpendicularity, and the approximate perpendicularity caused by processing errors and assembly errors (for example, the angle between two structural features is 89.9°) is also within the range of mutual perpendicularity in the present application.

[0030] See also Figures 1 to 3 As shown, Figure 1 A schematic cross-sectional structure diagram of an embodiment of a light emitting module provided by the present application is shown; Figure 2 A cross-sectional view of an embodiment of a light emitting module provided by the present application is shown. Figure 1 ,in, Figure 2 Three light emitting areas 11 are shown; Figure 3 A three-dimensional structural schematic diagram of an embodiment of a light emitting module provided by the present application is shown.

[0031] In a first aspect, the present invention provides a light emitting module, which includes: a light-transmitting panel 10 , a housing 20 , an electronic component 30 , a plurality of piezoelectric sensors 40 and a light source 50 .

[0032] The light-transmitting panel 10 is arranged to form a plurality of light-emitting areas 11 at intervals along a first direction; the shell 20 and the light-transmitting panel 10 are enclosed to form a light-emitting chamber 21; the electronic control assembly 30 is located in the light-emitting chamber 21; the piezoelectric sensor 40 corresponds to the light-emitting area 11 one by one, wherein the piezoelectric sensor 40 is located in the light-emitting chamber 21 and is electrically connected to the electronic control assembly 30, and the piezoelectric sensor 40 is configured to be able to sense the deformation of the shell 20 or the light-transmitting panel 10 and output a piezoelectric signal to the electronic control assembly 30; the light source 50 is located in the light-emitting chamber 21 and is electrically connected to the electronic control assembly 30.

[0033] In the embodiment of the present application, the upper surface of the light-transmitting panel 10 is divided into a plurality of blocks, which are the light-emitting areas 11, and the light-emitting areas 11 correspond to the piezoelectric sensors 40 one by one, so as to achieve independent sensing and independent light emission of each light-emitting area 11. The light-emitting chamber 21 composed of the light-transmitting panel 10 and the housing 20 can accommodate a variety of electronic components, such as Figure 1As shown, it includes a piezoelectric sensor 40, an electronic control group 30 and a light source 50, so that when a user applies pressure to the light-transmitting panel 10 (for example, the user steps on it), the piezoelectric sensor located in the light-emitting chamber 21 can detect the deformation of the shell 20 and the light-transmitting panel 10 and sense the current pressure position, thereby outputting a corresponding piezoelectric signal to the electronic control group 30, so that the electronic control group 30 can drive the corresponding light source 50 to light up according to the piezoelectric signal, thereby realizing an interactive lighting solution.

[0034] For example, the piezoelectric sensor 40 is a sensor that works by using the piezoelectric effect, which can convert mechanical vibration or stress into an electrical signal, that is, the piezoelectric sensor can detect extremely small structural deformations and emit piezoelectric signals. Compared with conventional resistive pressure sensors, the housing 20 can be made of a stronger material, such as stainless steel, aluminum alloy, carbon steel and other metal materials, which is not limited in this application.

[0035] Therefore, when the light-emitting module is embedded in the automobile light-emitting pedal, the durability of the automobile light-emitting pedal can be enhanced. In addition, the above-mentioned interactive lighting scheme does not emit light when not under pressure, which can reduce visual interference to passengers or drivers. When under pressure, its light-emitting mode can also personalize the pattern and color of the light source 50, thereby improving the aesthetics of the automobile light-emitting pedal. Exemplarily, the light-emitting module extends along the first direction and has a plurality of light-emitting areas 11.

[0036] In some embodiments, the light emitting chamber 21 further includes a light-homogenizing film 14 , which is attached to the inner side of the light-transmitting panel 10 along the third direction, so as to make the light emitted by the light source 50 softer and more uniform, thereby improving the display effect of the light-transmitting panel 10 .

[0037] In some embodiments, the electronic group control 30 includes electronic components 31 and a PCB board 32, wherein the electronic components 31 are arranged at intervals along the first direction and correspond one to one with the light-emitting area 11 and the piezoelectric sensor 40; the PCB board 32 extends along the first direction and is located between the light source 50 and the piezoelectric sensor 40 along the third direction. Exemplarily, the above-mentioned light-emitting method is a segmented light-emitting scheme, in which one PCB board 32 corresponds to one piezoelectric sensor 40, and preferably three to four piezoelectric sensors 40 are integrated into one PCB board 32, so that one PCB board 32 controls three to four light-emitting sensing areas, which is not limited in this application.

[0038] In the embodiment of the present application, the electronic component 31 refers to an electronic component used to perform specific electronic functions (such as signal amplification, conversion, control and storage). Through the layout of the electronic component 31 and the PAC board, precise control of each light-emitting area 11 is achieved. Figure 2As shown, the LED lights are arranged at intervals on the PCB board 32, and can be combined with the PCB board 32 to form a light strip. Among them, the LED lights can be multi-color LED lights or single-color LED lights, and their light-emitting modes can be constant light, breathing light, flashing and other effects, which are not limited in this application.

[0039] In some embodiments, the electronic group control 30 is used to receive the piezoelectric signal of the piezoelectric sensor 40, and output a corresponding PWM signal to the light source 50 according to the piezoelectric signal; wherein the light source 50 includes a plurality of LED lights arranged at intervals along a first direction, and the LED lights can display corresponding brightness according to the PWM signal.

[0040] In the embodiment of the present application, PWM (Pulse Width Modulation) is pulse width modulation, which controls the average value of the output voltage by adjusting the width of the pulse, thereby controlling the brightness of the corresponding LED lamp. Among them, the electronic group control 30 uses a PWM signal to accurately adjust the brightness of the LED lamp, which can achieve more diverse lighting modes. For example, the electronic group control 30 adjusts the brightness of the LED lamp so that the brightness of the LED lamp can change according to the change of the pressure value, thereby realizing a more personalized pressure sensing and visual feedback linkage lighting mode.

[0041] Combination Figure 4 As shown, Figure 4 A schematic diagram of a light emitting area 11 of an embodiment of a light emitting module provided in the present application is shown.

[0042] In some embodiments, the light-emitting area 11 includes a sensing area 110 and a lighting area 111. The sensing area 110 is a real-time pressure trigger area that can be sensed by the piezoelectric sensor 40, and the lighting area 111 is a stepless dimming area in which the electronic group control 30 can continuously adjust the brightness of the light source 50 according to the real-time pressure intensity of the sensing area 110.

[0043] In the embodiment of the present application, stepless dimming refers to the technology of continuously and steplessly adjusting the brightness and color temperature of light. The electronic group control 30 uses PWM signals to accurately adjust the LED lamp, so as to achieve stepless adjustment of the brightness of the LED lamp from 0% to 100%, thereby allowing the light-emitting area 11 to achieve a smoother and more comfortable dimming effect. For example, the lighting area 111 is symmetrically arranged in the sensing area 110. When the light-transmitting panel 10 is under pressure to form the sensing area 110, the multiple LED lamps in the lighting area 111 are sequentially lit, which can present a diffuse lighting visual effect to the user and improve the user experience.

[0044] For example, one lighting scheme is: the lighting area 111 is 100 mm extending outward from the sensing area 110; another lighting scheme is: the lighting area 111 is 300 mm radiating outward from the sensing area 110 as the center, etc. This application does not limit this.

[0045] See also Figure 5 As shown, Figure 5 A cross-sectional view of an embodiment of a light emitting module provided by the present application is shown. Figure 2 .

[0046] In some embodiments, in combination Figure 1 and Figure 5 As shown, the light-transmitting panel 10 is protruded from the outer edge of the shell 20 along the second direction to ensure that the pressure contact surface is located on the light-transmitting panel 10, and the light-transmitting panel 10 can transmit the pressure to the shell 20, thereby ensuring that there is no sensing blind spot of the piezoelectric sensor 40. Exemplarily, the light-transmitting panel 10 is also higher than the shell 20 along the third direction, and the light-transmitting panel 10 protruding from the outer edge of the shell 20 can also form a physical barrier to prevent liquid from entering the light-emitting chamber 21. Exemplarily, the light-transmitting panel 10 is a lens surface, which is slightly protruding from the shell 20 to facilitate the transmission of pressure to the bottom surface of the shell 20, so that the shell 20 is deformed and facilitates the pressure sensor 40 to sense.

[0047] In some embodiments, the light-transmitting panel 10 is provided with a first convex portion 12 and a second convex portion 13 at intervals along the second direction; the shell 20 is provided with a first concave portion 22 and a second concave portion 23 at intervals along the second direction, the first concave portion 22 is matched with the first convex portion 12, and the second concave portion 23 is matched with the second convex portion 13; wherein the piezoelectric sensor 40 is bonded to the bottom surface of the shell 20.

[0048] In the embodiment of the present application, the first convex portion 12 and the second convex portion 13, the first concave portion 22 and the second concave portion 23 are respectively buckled to ensure the stability and sealing of the connection between the light-transmitting panel 10 and the housing 20. Among them, bonding the piezoelectric sensor 40 along the bottom surface of the housing 20 can effectively detect the extremely small deformation of the housing 20, and compared with bonding the piezoelectric sensor 40 to the light-transmitting panel 10, it can avoid interfering with the lighting effect of the light source 50. Exemplarily, the piezoelectric sensor 40 and the bottom surface of the housing 20 can be bonded by ultrasonic bonding or glue.

[0049] Exemplarily, the piezoelectric sensor 40 is disposed on one side of the bottom surface of the shell 20, which can effectively avoid being disposed on one side of the light-transmitting panel 10 and affecting the light transmission and lighting effects, and there is no need to select the transparent piezoelectric sensor 40 to increase the process complexity. And compared with the resistive pressure sensor in the prior art that requires excessive pressure to be triggered, the above-mentioned piezoelectric sensor 40 can sense the extremely small stress state of the light-transmitting panel 10 through the shell 20. Therefore, in order to trigger the lighting effect, the user does not need to step on the light-transmitting panel 10 vigorously, and the deformation of the luminous pedal is effectively avoided. In addition, the shell 20 can also be made of stronger materials, such as steel plates, alloys, etc. The piezoelectric sensor 40 is a piezoelectric sensing chip, which can sense the slight deformation pressure of the shell 20.

[0050] In some embodiments, the housing 20 further includes a fixing bracket 24, which is located in the light-emitting chamber 21, wherein the fixing bracket 24 includes a plurality of bolts 240 spaced apart along a first direction, and the bolts 240 penetrate the PCB board 32 along a third direction and abut against the bottom surface of the housing 20. The fixing bracket 24 is provided to further enhance the structural strength of the light-emitting module so that it can withstand greater pressure.

[0053] In the embodiment of the present application, the above-mentioned light-emitting module is integrated into the automobile light-emitting pedal, and multiple light-emitting areas 11 are combined into a light panel area 62, so that it can be overall controlled by the MCU module 63. That is, multiple light-emitting modules cooperate with each other to form a larger lighting area or achieve a more personalized pattern effect.

[0054] In some application scenarios, pressing the position of any block can trigger the light source 50 of any block, for example Figure 8 In the embodiment, two adjacent light-emitting areas 11 form a light panel area 62, which can achieve a coordinated light-emitting effect. The present application does not limit the division of the light panel area 62. For example, Figure 7 The light strip is divided into three light panel areas 62, that is, the light strip composed of multiple LED lights is assembled into three light panel areas 62, and can also be assembled into 4 or 5 light panel areas 62, etc.

[0057] In the third aspect, the present application also provides a car, comprising: one or more of the above-mentioned car light-emitting pedals, a power module 70, a bus transceiver 71 and a BCM module 72. The power module 70 is electrically connected to the car light-emitting pedal; the bus transceiver 71 is connected to the MCU module 63 and the power module 70 of the car light-emitting pedal; the BCM module 72 is respectively connected to the power module 70 and the bus transceiver 71, so as to integrate the above-mentioned car light-emitting pedal into the car to realize the human-computer interaction function.

[0058] In some application scenarios, the BCM module 72 (Body Control Module) is a core component for coordinating and managing the vehicle body. The BCM module 72 is connected to the MCU module 63 for communication, so that multiple light sources 50 (for example, Fig. 9 The connection of each electrical component is as follows: Fig.10 As shown, in some application scenarios, when the user steps on the light-transmitting panel 10, the piezoelectric sensor 40 can promptly sense the stepping position, and transmit the piezoelectric signal to the MCU module 63, and the electronic group control 30 drives the light source 50 to achieve a preset light-emitting effect.

[0059] For example, in combination Fig.10 As shown, the car luminous pedal is connected to the power module 70 of the whole vehicle to provide power supply for the light source 50. The car luminous pedal is connected to the BCM module 72 through the bus transceiver 71, and the whole vehicle can also control the lighting of the light source 50, so that the car luminous panel can achieve a welcoming effect.
