Description

Technical Field

[0001] This application relates to the technical field of vehicle lights, and particularly to a vehicle light system and a mobile device. Background Art

[0002] The vehicle lights of existing mobile devices are usually controlled by the host system of the mobile device. When the vehicle lights need to be replaced due to damage, a vehicle light that matches the host system needs to be replaced for use.

[0003] In other words, the user needs to purchase the corresponding vehicle lights in order to repair and replace them. This not only increases the repair cost, but also for some scarce model vehicle lights, the user may need to spend more time waiting and cannot perform the repair and replacement in time. Summary of the Invention

[0004] The purpose of this application is to provide a vehicle light system and a mobile device, which can be convenient for repair and replacement without matching the host system of the mobile device.

[0005] To achieve the above purpose, on the one hand, this application provides a vehicle light system. The vehicle light system at least includes a lamp body and a light sensor. Among them, the light sensor is configured to detect whether there is an external light source; the lamp body includes a lighting unit, a vibration sensor and a controller. The vibration sensor is configured to detect whether there is vibration; the controller is electrically connected to the light sensor, the vibration sensor and the lighting unit, and the controller is configured to turn on the lighting unit when the vibration sensor detects vibration and the light sensor detects that there is no external light source.

[0006] To achieve the above purpose, on the other hand, this application also provides a mobile device. The mobile device includes a fuselage and the above vehicle light system; there are two vehicle light grooves on the fuselage, and the two lamp bodies are respectively installed in the two vehicle light grooves, and the controllers of the two lamp bodies are connected to the power supply of the fuselage.

[0007] As can be seen, in the technical solution provided by this application, a controller, a vibration sensor, and a lighting unit are installed inside the lamp body. The controller is electrically connected to the light sensor, the vibration sensor, and the lighting unit, and the controller is configured to turn on the lighting unit when the vibration sensor detects vibration and the light sensor detects the absence of an external light source. In other words, the lamp body has an independent control system, which can judge whether to turn on or off the lighting unit according to the detection signals of the vibration sensor and the light sensor, so that there is no need to connect the lamp body to the host system of the mobile device for control. In this way, when the lamp body of the mobile device needs to be repaired or replaced, the lamp body can be directly installed into the corresponding headlight groove on the mobile device, and it can be used in cooperation with the light sensor without considering the problem of matching with the host system of the mobile device, which is convenient for repair and replacement. At the same time, when directly installing the lamp body on the mobile device, there is no need to consider the signal line wiring problem between the lamp body and the host system, and the installation is simpler and more convenient.

[0014] To make the objectives, technical solutions and advantages of this application clearer, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0016] The headlights of existing mobile devices are usually controlled by the host system of the mobile device. When the headlights are damaged and need to be replaced, a headlight that matches the host system needs to be replaced before it can be used.

[0017] In other words, the user needs to purchase the corresponding headlights in order to repair and replace them. This not only increases the repair cost, but also for some scarce model headlights, the user may need to spend more time waiting and cannot perform the repair and replacement in a timely manner. Moreover, when replacing, attention needs to be paid to the accuracy of the signal line connection between the headlights and the host system, and the operation is troublesome.

[0018] Therefore, how to improve the structure of the headlight system and the mobile device, and then it can be made unnecessary to match the host system of the mobile device, and the repair and replacement rate can be facilitated, has become an urgent problem to be solved in this field.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings. Obviously, the embodiments described in this application are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of this application.

[0020] Please also refer to Figures 1 to 2 In an implementable embodiment, the vehicle lamp system may at least include a lamp body 100 and a light sensor 200. Among them, the light sensor 200 is configured to detect whether there is an external light source. In this embodiment, the working principle of the light sensor 200 is generally based on the photoelectric effect, that is, when light irradiates certain materials, changes in charge or voltage will occur. The light sensor 200 can adopt different technologies and materials, such as a photoresistor, a photodiode, a phototransistor, etc.

[0021] In practical applications, as Figure 3 shown, the light sensor 200 can be integrated on the vehicle charger 400. When the vehicle charger 400 is plugged into the cigarette lighter of the mobile device, the cigarette lighter powers the vehicle charger 400, and then powers the photoelectric sensor 200 integrated on the vehicle charger 400. Of course, the light sensor 200 can also be installed on the glass of the mobile device or on the outer surface of the housing of the lamp body 100, and the power supply of the mobile device powers the light sensor 200. The light sensor 200 can also be installed in other places where the external light source can be detected. This application does not make specific limitations on this.

[0022] In this embodiment, the lamp body 100 may include a lighting unit 120, a vibration sensor 130, and a controller 140. Among them, the lighting unit 120 can adopt an LED lamp, a halogen lamp, a xenon lamp, etc. This application does not make specific limitations on this. The vibration sensor 130 is configured to detect whether there is vibration, so as to judge whether the mobile device is started through the vibration detected by the vibration sensor 130. The controller 140 is electrically connected to the light sensor 200, the vibration sensor 130, and the lighting unit 120, and the controller 140 is configured to turn on the lighting unit 120 when the vibration sensor 130 detects vibration and the light sensor 200 detects that there is no external light source.

[0023] It is worth mentioning that by improving the lamp body 100 to judge whether to turn on or off the lighting unit 120 according to the detection signals of the vibration sensor 130 and the light sensor 200, it is not necessary to connect the lamp body 100 to the host system of the mobile device and control the opening and closing by the host system. In this way, when the lamp body 100 of the mobile device needs to be repaired or replaced, the lamp body 100 can be directly installed in the corresponding vehicle lamp groove of the mobile device and can be used in cooperation with the light sensor without considering the problem of matching with the host system of the mobile device, which is convenient for repair and replacement. At the same time, when directly installing the lamp body 100 on the mobile device, there is no need to consider the signal line wiring problem between the lamp body and the host system, and the installation is simpler and more convenient.

[0024] In an achievable implementation, the lamp body 100 further includes a power cord 150. The controller 140 is connected to the power supply of the mobile device through the power cord 150 to obtain the power consumption. Correspondingly, the controller 140 is further configured to, when the power supply of the mobile device supplies power to the controller 140 through the power cord 150, the controller 140 distributes the power supply to the vibration sensor 130 so that the vibration sensor 130 detects whether there is vibration.

[0025] For example, taking the lamp body 100 and the light sensor 200 installed on the mobile device as an example, when the mobile device is started, the power supply of the mobile device automatically supplies power to the controller 140. The controller 140 distributes the power supply to the vibration sensor 130 so that the vibration sensor 130 starts to perform vibration detection. And because the mobile device is started and the engine of the mobile device runs, the whole vehicle body vibrates, so that the vibration sensor 130 detects that there is vibration. At the same time, the power supply of the mobile device supplies power to the light sensor 200 so that the light sensor 200 starts to perform external light source detection. Of course, the light sensor 200 can also use an internal power supply, etc. The present application does not make specific limitations on this.

[0026] In an achievable implementation, the controller 140 is connected to the light sensor 200 in a wireless connection manner. In this way, the wiring harness arrangement between the controller 140 and the light sensor 200 does not need to be considered, which facilitates the installation operation. In practical applications, the wireless signal transmitted between the controller 140 and the light sensor 200 is a 2.4G wireless signal, so as to have the advantages of long transmission distance, strong anti-interference ability, fast transmission rate, etc.

[0027] In this implementation, the controller 140 can also be configured to, when the vibration sensor 130 detects that there is no vibration, the controller 140 turns off the lighting unit 120; when the vibration sensor 130 detects that there is vibration and the light sensor 200 detects that there is an external light source, the controller 140 turns off the lighting unit 120.

[0028] In practical applications, it can be understood that there are two relays connected in series on the path between the controller and the lighting unit 120. The two relays are used to jointly control the on / off of the path. The opening and closing of one relay is controlled by the signal of the vibration sensor 130. When the vibration sensor 130 detects vibration, it sends a closing signal; otherwise, it sends an opening signal. The opening and closing of the other relay is controlled by the signal of the photoelectric sensor 200. When the photoelectric sensor 200 detects an external light source, it sends an opening signal; otherwise, it sends a closing signal. Thus, the lighting unit 120 can be lit only when both relays are closed. It should be noted that the relays can be integrated inside the controller 140 and form an integral body with the controller 140. Of course, the relays and the controller 140 can also be set separately. The controller 140 receives the signals of the photoelectric sensor 200 and the vibration sensor 130, and based on these signals, sends corresponding signals to control the on / off of the corresponding relays.

[0029] To avoid misjudgment of the external light source signal. For example Figure 4 As shown, in an implementable embodiment, the light sensor 200 sends a wireless signal to the controller 140 at a preset time interval t. The controller 140 is further configured to continuously collect the wireless signals sent by the light sensor 200 within a time period of 5t, and determine whether the wireless signals within the 5t time period all indicate the absence of a light source. If so, the controller 140 turns on the lighting unit 120; otherwise, the controller 140 turns off the lighting unit 120.

[0030] In practical applications, the controller 140 usually uses AD sampling to detect the wireless signal of the light sensor 200. Specifically, the analog signal sent by the light sensor 200 is sampled and quantized to be converted into a digital signal for the controller 140 to process and analyze. The time interval t can be 2s, 1s, 100ms, etc. Of course, the sensitivity of the light sensor 200 can also be adjusted according to actual usage requirements, and the present application does not make specific limitations on this.

[0031] In this embodiment, the controller 140 is further configured to determine that the light sensor 200 has a fault when no wireless signal sent by the light sensor 200 is received within a time period of 10t, and then the controller 140 turns off the lighting unit 120.

[0032] In practical applications, there are two lamp bodies 100, and the two bodies 100 are respectively installed in two headlight grooves at the front end of the mobile device. The light sensors 200 are respectively wirelessly connected to the controllers 140 of the two lamp bodies 00. Of course, there can also be four lamp bodies 100, and the light sensors 200 are respectively wirelessly connected to the controllers 140 of the four lamp bodies 100.

[0033] Based on the same inventive concept, as Figure 3 shown, the present application further provides a mobile device, which includes a fuselage 300 and the above-mentioned vehicle lamp system; there are two lamp grooves on the fuselage 300, and the two lamp bodies 00 are respectively installed in the two lamp grooves, and the controllers 140 of the two lamp bodies 100 are connected to the power supply of the fuselage 300.

[0034] Preferably, the light sensor 200 is installed on the fuselage 300 or on the vehicle glass of the mobile device.

[0035] It should be noted that the specific structure of the lamp body 100 can refer to the content in the above-mentioned embodiments, and will not be elaborated here. The mobile device can be a device such as an automobile, a toy car, a cruise robot, etc.

[0036] Thus, in the technical solution provided by the present application, a controller, a vibration sensor and a lighting unit are installed in the lamp body. The controller is electrically connected to the light sensor, the vibration sensor and the lighting unit, and the controller is configured to turn on the lighting unit when the vibration sensor detects vibration and the light sensor detects the absence of an external light source. In other words, the lamp body can judge whether to turn on or off the lighting unit according to the detection signals of the vibration sensor and the light sensor, so that there is no need to connect the lamp body to the host system of the mobile device for control of opening and closing. In this way, when the lamp body of the mobile device needs to be repaired or replaced, the lamp body can be directly installed in the corresponding lamp groove on the mobile device, and then it can be used in cooperation with the light sensor without considering the problem of matching with the host system of the mobile device, which is convenient for repair and replacement. At the same time, when directly installing the lamp body on the mobile device, there is no need to consider the signal line wiring problem between the lamp body and the host system, and the installation is simpler and more convenient.

[0037] Furthermore, the controller is further configured to continuously collect the wireless signals sent by the light sensor within a time period of 5t, and judge whether the wireless signals within the time period of 5t all indicate the absence of an external light source. If so, the controller turns on the lighting unit, otherwise, the controller turns off the lighting unit. In this way, during the driving of the mobile device, the situations of oncoming vehicles or artificial illumination, etc., which are misjudged as the existence of an external light source, can be screened out, and the mis-opening of the lighting unit can be avoided.

[0038] The above are only the preferred embodiments of the present application, and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
