Abstract
Description
Technical Field

[0002] In order to better enjoy the fun of cycling and ensure cycling safety, cyclists often need to rely on the guidance of the navigation system. Existing cycling navigation mainly includes the following three methods: one is to check the mobile phone map or other navigation devices while riding or stopping; the second is to listen to the navigation information by wearing headphones; the third is to wear a watch, which will vibrate to remind the navigation route according to the destination set before departure.
[0003] However, there are safety risks when checking mobile phone maps while riding, especially when the route is complicated. Frequently looking down at the navigation will distract the rider and increase the risk of traffic accidents. Although wearing headphones to listen to navigation information is convenient, it will affect the rider's perception of the surrounding environment, which also poses safety risks and is easily disturbed by surrounding noise, resulting in unclear navigation information. In addition, although the vibration reminder method of the watch avoids visual and auditory interference, the reminder method is single and inaccurate, and is easily affected by the vibration of the vehicle during riding, making it difficult to give correct guidance.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.
[0027] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
[0028] Example:
[0029] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0030] Please refer to Figure 1 The laser array module 10 includes: a substrate 11; a plurality of lasers 12 arranged in a two-dimensional array on the substrate 11; and a laser moving unit for causing the designated laser 12 to perform axial rotation and / or tilt movement along a predetermined direction in response to a control signal; wherein, when a single laser 12 tilts and moves along a predetermined direction, the persistence of vision of the human eye is utilized to cause the light beam emitted by the laser 12 to form a corresponding light band on a projection surface, thereby utilizing the plurality of light bands to be combined into a corresponding graphic symbol.
[0031] It should be noted that the human eye has a phenomenon of persistence of vision, that is, when the light changes rapidly, the human eye will retain the visual impression of the previous moment, forming a continuous visual perception. In the above embodiment, by utilizing this principle, a single laser 12 is tilted and moved in a predetermined direction, so that the light beam it emits forms a corresponding light band on the projection surface. This dynamic change of light band can simulate richer visual effects. Therefore, through the coordinated work of multiple lasers 12 and the precise control of the laser moving unit, multiple light bands can be combined into corresponding graphic symbols on the projection surface. This projection method of graphic symbols is not only highly flexible, but also can achieve complex graphic transformations and dynamic effects. In addition, traditional laser projection systems can often only achieve static light beam projection, while the present application introduces a laser moving unit, so that the laser 12 can move dynamically in response to the control signal, thereby achieving dynamic changes of the light beam on the projection surface.
[0032] That is to say, through the dynamic control of the laser by the laser moving unit and the application of the human eye persistence of vision phenomenon, the technical solution of the present invention can form rich light bands and graphic symbols on the projection surface, thereby greatly enhancing the visual effect and making the projected content more vivid and three-dimensional. Therefore, if the laser array module 10 is installed on a riding vehicle and then the corresponding control signal is obtained by using the navigation information generated on a mobile terminal such as a mobile phone, so that the corresponding laser 12 rotates axially and / or tilts and moves in a predetermined direction, the navigation pattern and / or navigation text and / or navigation icon can be projected and displayed on the ground in front of the riding vehicle, thereby greatly improving the navigation method of the riding vehicle in terms of user experience and safety. Specifically, in the traditional mobile phone navigation mode, the rider needs to look down at the mobile phone and cannot keep the line of sight always looking straight ahead, so it is easy to have an accident due to looking down at the mobile phone. In the present application, the rider can see the navigation information in front of the riding vehicle in real time and does not need to stop or distract to operate the mobile phone, which will make the riding more smooth and convenient. In addition, the screen of the mobile phone may be directly irradiated by sunlight or affected by rain during riding, the navigation prompt sound is affected by noise, and the vibration prompt is affected by the riding terrain and the degree of bumpiness, while the graphic symbols projected by the laser array module 10 are not affected by this. Moreover, even in a relatively dark environment, the navigation information can be clearly displayed, which can enhance the safety and visibility of night riding.
[0033] To enable those skilled in the art to more intuitively understand the present application, a specific example will be used for illustration here.
[0034] As Figure 1 shown, assume that a laser array module 10 includes 36 lasers 12 (for simplified representation, Figure 1 the lasers 12 in
[0035] are represented by a rectangular frame) and are numbered 1-36 respectively. Assume that the graphic symbol to be projected currently is the character "left", then it can be controlled in the following way:
[0036] 1) First, the stroke order of the character "left" is successively "-", " / ", "-", "|", "-". To display the first horizontal stroke "-" of the character "left", the lasers 12 numbered 8, 9, 10, and 11 are simultaneously controlled to tilt and move left and right repeatedly, thereby generating a light band to form the first horizontal stroke "-".
[0037] 3) Next, in order to display the third horizontal stroke '一' of the character '左', the 15th, 16th, and 17th lasers 12 are respectively controlled to tilt left and right repeatedly, thereby generating a light band to form the third horizontal stroke '一'.
[0039] 4) Then, in order to display the fourth vertical stroke '|' of the character '左', the 21st laser 12 is controlled to tilt up and down repeatedly, generating a light band to form the fourth vertical stroke '|'.
[0040] 5) Finally, in order to display the fifth horizontal stroke '一' of the character '左', the 15th, 16th, and 17th lasers 12 are respectively controlled to tilt left and right repeatedly, thereby generating a light band to form the fifth horizontal stroke '一'. Thus, the final displayed graphic will be as Figure 2 shown.
[0041] For another example, if the graphic symbol to be projected currently is a right-turn icon, it can be controlled in the following way:
[0042] Control the 5th, 17th, and 11th lasers 12 to rotate 45°, so as to generate slanted light bands. The 7th laser 12 maintains its central position unchanged and projects a point. The 4th, 8th, 9th, 10th, 15th, 16th, 22nd, and 27th lasers 12 tilt left and right repeatedly, generating a horizontal light band of '一', and the 16th, 21st, 28th, 14th, 23rd, and 26th lasers 12 tilt up and down repeatedly, generating a vertical light band of '丨'. Thus, these light bands of points, horizontal lines, vertical lines, and slanted lines with a certain width are used together to form a Figure 3 right-pointing icon as shown. It should be noted that since the light bands have a certain width, when the lasers 12 are arranged densely enough, a fully filled right-turn icon inside a graphic can be displayed.
[0043] Please refer to Figure 4 , in some implementation manners of the present application, the laser moving unit includes a plurality of laser moving modules that are one-to-one matched with the number of lasers 12. Any one of the laser moving modules is used to respond to a control signal and control the laser 12 matched with it to perform axial rotation and / or tilt and move along a predetermined direction. Wherein, one end of each laser 12 is made of a magnetic material, and any one of the laser moving modules includes an electromagnet 13 for controlling the laser 12 to tilt and move along a predetermined direction, and a motor for controlling the laser 12 to perform axial rotation ( Figure 4 not shown in Figure 4 , one end of the universal joint drive shaft 14 in
[0044] In the above implementation, the laser moving unit is composed of a plurality of laser moving modules matched one-to-one with the laser 12, and each laser moving module can independently respond to the control signal, thereby controlling the matched laser 12 to perform axial rotation and / or tilt movement along a predetermined direction. Thus, the movement of the laser 12 can be controlled more accurately, and the direction and position of the laser beam can be flexibly controlled, so as to better project the corresponding graphic symbol.
[0045] Each laser moving module includes an electromagnet 13, which is used to control the tilting movement of the laser 12 in a predetermined direction. The working principle of the electromagnet 13 is to generate magnetic fields of different strengths by changing the current inside it, thereby attracting or repelling one end of the laser 12 made of magnetic material to achieve the tilting movement of the laser 12. By accurately controlling the current in the electromagnet 13, the magnetic force generated by it can be adjusted, thereby controlling the speed of the tilting movement of the laser 12. When the laser 12 needs to tilt quickly, the current in the electromagnet 13 can be increased to generate a stronger magnetic force; conversely, when the laser 12 needs to tilt slowly, the current in the electromagnet 13 can be reduced to reduce the magnetic force it generates. This control method is not only simple and direct, but also can achieve precise speed regulation.
[0046] Please refer to Figure 4 In some implementations of the present application, any laser moving module includes an electromagnet 13 for controlling the laser 12 to move tilted along a first direction, and an electromagnet 13 for controlling the laser 12 to move tilted along a second direction.
[0047] In the above implementation, the two electromagnets 13 are responsible for controlling the laser 12 in two directions (i.e., the first direction and the second direction, Figure 4 What is shown is the tilting movement in two orthogonal directions (x and y). This design not only improves the flexibility and accuracy of the laser moving module, but also ensures that the laser beam can be adjusted at any angle and position in a two-dimensional plane to generate better quality graphic symbols. And compared with the solution of using more complex mechanical structures or more sensors to achieve similar functions, the laser moving module in this implementation achieves an efficient and cost-effective solution through a simple electromagnet 13 design.
[0048] Please refer to Figure 4 In some implementations of the present application, any laser moving module includes a plurality of electromagnets 13 symmetrically distributed at one end of the laser 12 made of magnetic material and used to control the laser 12 to tilt and move in a predetermined direction.
[0049] In the above implementation, by synchronously controlling the polarity of the electromagnets 13 on both sides, an acceleration force can be quickly generated, so that the laser 12 can tilt and move faster in a predetermined direction. This improves the response speed of the system, allowing the laser beam to be positioned at the target position faster. For example, when the electromagnet 13 on the left drives the laser 12 to tilt to the left, the electromagnet 13 on the right is synchronously controlled to produce the opposite polarity, which can accelerate the laser 12 to tilt to the left. In addition, since the electromagnets 13 on both sides act at the same time, the force on the laser 12 can be balanced, avoiding the deflection or instability that may occur when a single electromagnet 13 acts. This balanced force helps to maintain the stable tilt movement of the laser 12.
[0050] Please refer to Figure 4 In some implementations of the present application, the output shaft of the motor is connected to the laser 12 via a universal joint transmission shaft 14 to drive the laser 12 to rotate axially.
[0051] Driven by the motor, the output shaft starts to rotate. This rotational motion is transmitted to the laser 12 through the universal joint transmission shaft 14, thereby driving the laser 12 to rotate axially. Due to the flexibility and stability of the universal joint transmission shaft 14, the laser 12 can be rotated at any desired angle, so that after the laser array module 10 is fixed to the riding vehicle, the projection surface of the graphic symbol can be easily adjusted.
[0052] In some implementations of the present application, the laser array module 10 also includes a navigation information processing unit for receiving navigation information and converting it into a control signal to control the designated laser 12 to perform axial rotation and / or tilt movement in a predetermined direction, thereby combining and displaying graphic symbols related to the navigation information on the projection surface.
[0053] In the above implementation, the navigation information is received by the navigation information processing module and converted into a control signal, which can provide intuitive and clear navigation guidance for the rider. This navigation method not only reduces the number of times the driver's line of sight shifts, but also improves driving safety. The navigation information may include key data such as position, direction, speed, etc. The graphic symbols related to the navigation information displayed in combination on the projection surface may include arrows, route instructions, distance marks, etc., to provide users with intuitive and clear navigation guidance.
[0054] In some implementations of the present application, the navigation information processing unit includes an interface that is communicatively connected to the mobile terminal to receive navigation information provided by a navigation application on the mobile terminal.
[0055] In the above implementation, the navigation information processing unit is equipped with an interface for communication connection with the mobile terminal. This interface may use wireless communication technology (such as Bluetooth, Wi-Fi, mobile communication network, etc.) or wired communication technology (such as USB, serial port, etc.) to achieve connection with the mobile terminal. Thus, the navigation information processing unit can receive navigation information sent by the mobile terminal (mobile phone, smart watch, etc.) through the interface, parse and process it, and then generate corresponding control signals according to the specific content of the navigation information, which are used to control the specified laser 12 in the laser array module 10 to rotate axially and / or tilt along a predetermined direction.
[0056] Please refer to Figure 5 The embodiment of the present application also provides a navigation method for a riding vehicle, which includes: receiving navigation information transmitted by a mobile terminal device, and converting the navigation information into a corresponding control signal; controlling the laser array module 10 to project a navigation pattern and / or navigation text and / or navigation icon on the ground according to the control signal.
[0057] It should be noted that by using the laser array module 10 to project navigation patterns and / or navigation texts and / or navigation icons on the ground ( Figure 5 The method can provide riders with intuitive and easy-to-understand navigation guidance. Compared with traditional navigation methods, this method reduces the number of times riders check navigation devices and the degree of distraction, thereby improving riding safety. In addition, riders can obtain navigation information without carrying additional navigation devices or checking the screen of their mobile phones, making the riding process more convenient and comfortable.
[0058] In specific implementation, the processing logic can be as follows:
[0059] First, navigation information is received from a mobile terminal device (such as a smart phone, smart watch, tablet computer, etc.) through a certain communication method (such as Bluetooth, Wi-Fi, mobile communication network, etc.). The navigation information may include key data such as the rider's current location, destination, route planning, direction indication, etc. Then, the received navigation information will be parsed and processed by the navigation information processing unit. Thus, according to the specific content of the navigation information, the navigation information processing unit will generate corresponding control signals. These control signals will be directly used to control the laser 12 in the laser array module 10 to move and / or rotate. Finally, according to the control signal, the laser 12 in the laser array module 10 will project a navigation pattern on the ground according to a predetermined trajectory and speed. These patterns may include route indication arrows, turn marks, distance marks, etc., to provide intuitive navigation guidance for riders. In addition to the navigation pattern, the laser array module 10 can also project navigation text and / or icons on the ground. These texts and icons may include direction indications, place name labels, traffic signs, etc., to provide riders with more detailed navigation information.
[0060] Please refer to Figure 6 , an embodiment of the present application also provides a riding vehicle, which includes a laser array module 10.
[0061] It should be noted that the laser array module 10 can project clear navigation patterns, texts and / or icons on the ground according to the received navigation information. These navigation information include the rider's current location, destination, route planning, direction instructions, etc., providing intuitive and accurate navigation guidance for the rider. In addition, at night or in a dimly lit riding environment, the navigation information projected by the laser array module 10 is more eye-catching and easy to identify, which helps the rider maintain the correct direction of travel. At the same time, the laser array module 10 can also be used as a warning light to remind other road users of the presence of the riding vehicle. In short, providing an integrated laser array module 10 on a riding vehicle can not only improve the functionality and user experience of the riding vehicle, but also bring a safer, more convenient and interesting riding experience to the rider.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
