[0028] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0029] The first embodiment of the present application is as follows:

[0030] Please refer to Figures 1 to 4 where Figure 1 is an exploded view of the structure of the first embodiment of the present invention. Figure 2 is a schematic diagram of the split structure of the first embodiment of the present invention. Figure 3 is the Figure 2 enlarged view of the partial structure at A of the present invention. Figure 4 is a principle block diagram of the first embodiment of the present invention.

[0031] The present invention provides a backlight - display LED - emitting switch for two - wheel or three - wheel vehicles, including a five - way switch 101, a fixed rear cover 102, a light - emitting component 103, a fastening bolt 104, a light - emitting lamp bead 105, a keycap, and a control system. The control system includes an ambient light sensing module 112, a signal processing module 113, a light intensity detection module 114, and a brightness adjustment module 115. The ambient light sensing module 112 includes an ambient light sensor 116 and a signal conditioning sub - module 117. The signal processing module 113 includes an analog - to - digital converter 118 and a digital filter 119. The keycap includes a keycap body 106 and a plurality of elastic components 107. The above - mentioned solution solves the technical problem in the prior art that the combined switch operates smoothly in good daylight, but in rainy days and at night with poor light, it is difficult for the driver to clearly see the switch position and markings, and can only operate by experience, which is extremely easy to press by mistake or operate inaccurately.

[0032] For this specific embodiment, the light-emitting member 103 is disposed on the fixed rear cover 102, the light-emitting lamp beads 105 are disposed on a surface of the light-emitting member 103 away from the light-emitting member 103, the light-emitting member 103 and the fastening rear cover are respectively provided with a first through hole 108 and a second through hole 109, one end of the fastening bolt 104 sequentially passes through the first through hole 108 and the second through hole 109, and is tightened on the five-way switch 101, and the keycap is snap-connected to the fixed rear cover 102;

[0033] The number of the light-emitting lamp beads 105 is multiple, and the multiple light-emitting lamp beads 105 are uniformly distributed along the axial center line of the first through hole 108;

[0034] During specific use, first install the light-emitting lamp beads 105 on the light-emitting member 103, then one end of the fastening bolt 104 sequentially passes through the first through hole 108 and the second through hole 109, and is tightened on the five-way switch 101, so that the fixed rear cover 102 can be fixed on the five-way switch 101, and at this time the light-emitting member 103 is fixed on the fixed rear cover 102. After that, snap the keycap on the fixed rear cover 102 to complete the assembly. By emitting light through the multiple light-emitting lamp beads 105, the positions of the operation points of the five-way switch 101 can be normally displayed, realizing intelligent and accurate control of the vehicle. In this way, in the case of poor lighting, the switch can still be accurately recognized and conveniently operated, greatly avoiding the phenomenon of misoperation, thereby solving the technical problem in the prior art that the combination switch can be operated without hindrance in good daylight, but in rainy days and at night with poor lighting, it is difficult for the driver to see the position and markings of the switch clearly, and can only operate by experience, easily mispressing or operating inaccurately.

[0035] Wherein, the fixed rear cover 102 has a plurality of clamping holes 110, one ends of the plurality of elastic members 107 are fixedly connected to the keycap body 106, and the other ends of the plurality of elastic members 107 are respectively clamped with the corresponding clamping holes 110;

[0036] Each elastic member 107 has a resisting inclined surface 111. During specific use, align the plurality of elastic members 107 with the corresponding clamping holes 110 respectively, so that the resisting inclined surface 111 contacts the corresponding clamping hole 110, and continue to push the keycap body 106 until the clamping hole 110 resists the deformation of the elastic member 107. Continue to push. After pushing to the specified position, the elastic member 107 is reset and clamped in the corresponding clamping hole 110 to complete the assembly between the keycap body 106 and the fixed rear cover 102.

[0037] Secondly, the keycap body 106 is made of a light-transmitting material or a semi-light-transmitting material. By using a light-transmitting material or a semi-light-transmitting material to make the keycap body 106, the light conduction of the light-emitting lamp beads 105 can be realized, which is convenient for the driver to observe.

[0038] Meanwhile, the signal processing module 113 is connected to the ambient light sensing module 112, the light intensity detection module 114 is connected to the signal processing module 113, the brightness adjustment module 115 is connected to the light intensity detection module 114, and the brightness adjustment module 115 is connected to a plurality of the light-emitting lamp beads 105;

[0039] The ambient light sensing module 112 collects ambient light data in real time;

[0040] The signal processing module 113 is used to process the ambient light data and then transmit it to the light intensity detection module 114;

[0041] The light intensity detection module 114 classifies the ambient light collected in real time;

[0042] The brightness adjustment module 115 automatically adjusts the brightness of the light-emitting lamp beads 105 according to the ambient light level collected in real time.

[0043] In addition, the signal conditioning sub-module 117 is connected to both the ambient light sensor 116 and the implementation signal processing module 113;

[0044] The ambient light sensor 116 is used to detect the light intensity in the environment in real time and transmit it to the signal conditioning sub-module 117;

[0045] The signal conditioning sub-module 117 is used to amplify and filter the received light intensity signal.

[0046] Again, the analog-to-digital converter 118 is used to convert the analog light intensity signal into a digital signal, and the digital filter 119 uses a software filtering algorithm to remove the noise and interference of the signal.

[0047] Specifically, the specific control method of the light-emitting lamp beads 105 is as follows:

[0048] The ambient light sensor 116 detects the front, left, and right light signals, eliminates local occlusion interference, and then the signal conditioning sub-module 117 amplifies and filters the received light intensity signal;

[0049] Subsequently, the analog-to-digital converter 118 converts the analog light intensity signal into a digital signal, and the digital filter 119 uses a software filtering algorithm to remove the noise and interference of the signal;

[0050] The light intensity detection module 114 classifies the ambient light collected in real time into intervals divided according to the ambient light intensity (such as daytime / dusk / night / tunnel).

[0051] According to the divided intervals, the brightness adjustment module 115 automatically adjusts the brightness of the light-emitting lamp beads 105:

[0052] Extremely dark environment (0 - 10 lux): Adjust the brightness of the light-emitting lamp beads 105 to the maximum value to ensure that the driver can clearly see the switch.

[0053] Dark environment (10 - 50 lux): Adjust the brightness to 80% to save energy while ensuring visibility.

[0054] Medium environment (50 - 200 lux): Adjust the brightness to 50% to balance visibility and energy-saving effect.

[0055] Bright environment (200 - 500 lux): Adjust the brightness to 30% to avoid excessive brightness from affecting the driver's line of sight.

[0056] Extremely bright environment (above 500 lux): Adjust the brightness to 10% or directly turn off the backlight to prevent glare caused by reflection to the driver.

[0057] When using a two-wheel or three-wheel vehicle backlight display LED light-emitting switch of this embodiment, in specific use, first install the light-emitting lamp beads 105 on the light-emitting member 103, then pass one end of the fastening bolt 104 through the first through hole 108 and the second through hole 109 in sequence, and tighten it on the five-way switch 101, then the fixed rear cover 102 can be fixed on the five-way switch 101, and at this time the light-emitting member 103 is fixed on the fixed rear cover 102, and then snap the key cap on the fixed rear cover 102 to complete the assembly. By controlling multiple light-emitting lamp beads 105 to emit light through the control system, the positions of each operation point of the five-way switch 101 can be normally displayed, realizing intelligent and precise control of the vehicle, so that in the case of poor lighting, the switch can still be accurately recognized and conveniently operated, greatly avoiding the phenomenon of misoperation. In this way, it solves the technical problem in the prior art that the combination switch operates without hindrance in good daytime light, but in rainy days and at night with poor light, it is difficult for the driver to see the switch position and markings clearly, and can only operate by experience, which is extremely easy to mispress or operate inaccurately.

[0058] The specific control method of the light-emitting lamp beads 105 is as follows:

[0059] The front, left, and right light signals are detected by the ambient light sensor 116 to eliminate local occlusion interference, and then the received light intensity signal is amplified and filtered by the signal conditioning sub-module 117;

[0060] Subsequently, the analog-to-digital converter 118 converts the analog light intensity signal into a digital signal, and the digital filter 119 uses a software filtering algorithm to remove the noise and interference of the signal;

[0061] The light intensity detection module 114 classifies the ambient light collected in real time, and divides it into intervals according to the intensity of the ambient light (such as day / dusk / night / tunnel);

[0062] According to the divided intervals, the brightness adjustment module 115 automatically adjusts the brightness of the light-emitting lamp beads 105:

[0063] Extremely dark environment (0 - 10 lux): Adjust the brightness of the light-emitting lamp beads 105 to the maximum value to ensure that the driver can clearly see the switch.

[0064] Dark environment (10 - 50 lux): Adjust the brightness to 80% to save energy while ensuring visibility.

[0065] Medium environment (50 - 200 lux): Adjust the brightness to 50% to balance visibility and energy-saving effect.

[0066] Bright environment (200 - 500 lux): Adjust the brightness to 30% to avoid excessive brightness from affecting the driver's line of sight.

[0067] Extremely bright environment (above 500 lux): Adjust the brightness to 10% or directly turn off the backlight to prevent glare caused by reflection to the driver.

[0068] The second embodiment of the present application is:

[0069] Based on the first embodiment, please refer to Figure 5 , Figure 5 which is the principle block diagram of the second embodiment of the present invention.

[0070] The present invention provides a backlight display LED lighting switch for two-wheeled or three-wheeled vehicles, further including a dynamic weighting module 201, an abnormal rejection module 202, and a smooth transition module 203.

[0071] For this specific embodiment, the dynamic weighting module 201 is connected to the ambient light sensing module 112, and the anomaly rejection module 202 is connected to the dynamic weighting module 201. The dynamic weighting module 201 performs real-time weighted averaging on the light signal data in the front, left, and right directions: the weight of the front sensor is higher, and it responds preferentially to the light changes in the direction of the driver's line of sight. The anomaly rejection module 202 uses the sliding window method (window size = 5) to eliminate transient interferences (such as headlight flashes).

[0072] Among them, the smooth transition module 203 is connected to the brightness adjustment module 115. When switching between different light intensity levels, the smooth transition module 203 adjusts the brightness in a gradual manner to avoid discomfort to the driver's vision caused by sudden brightness changes. For example, when the light intensity gradually changes from a dark environment to a medium environment, the brightness gradually decreases from 80% to 50%, and the transition time can be set to 1 - 2 seconds.

[0073] When using a backlit display LED lighting switch for a two - wheel or three - wheel vehicle according to this embodiment, during actual use, the dynamic weighting module 201 is connected to the ambient light sensing module 112, and the anomaly rejection module 202 is connected to the dynamic weighting module 201. The dynamic weighting module 201 performs real - time weighted averaging on the light signal data in the front, left, and right directions: the weight of the front sensor is higher, and it responds preferentially to the light changes in the direction of the driver's line of sight. The anomaly rejection module 202 uses the sliding window method (window size = 5) to eliminate transient interferences (such as headlight flashes).

[0074] The smooth transition module 203 is connected to the brightness adjustment module 115. When switching between different light intensity levels, the smooth transition module 203 adjusts the brightness in a gradual manner to avoid discomfort to the driver's vision caused by sudden brightness changes. For example, when the light intensity gradually changes from a dark environment to a medium environment, the brightness gradually decreases from 80% to 50%, and the transition time can be set to 1 - 2 seconds.
