DETAILED DESCRIPTION

[0025] In order to make the technical problems to be solved by the present application, the technical solutions and the beneficial technical effects more clear, the present application will be further described in detail below in conjunction with the drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the protection scope of the present application, and each embodiment can share the same view or multiple views for description, but all the features appearing in the same view cannot be interpreted as the features that an embodiment must have.

[0026] The exemplary embodiments of the present application will be described below in conjunction with the drawings.

[0027] Figure 1 a schematic block diagram of an on-board hair cutting device 2000 for a vehicle 1000 according to an embodiment of the present application is shown;Figure 2 A schematic view of a vehicle 1000 is shown. Figure 2 A xyz coordinate system of the vehicle 1000 is also shown schematically, where x represents the longitudinal direction of the vehicle 1000, y represents the height direction of the vehicle 1000, and z, not shown here, represents the lateral direction of the vehicle 1000. For the sake of clarity, the xyz coordinate system is basically referred to in the subsequent figures.

[0028] Figure 3 A schematic application scenario of an in-vehicle hair cutting device 2000 for the vehicle 1000 is shown according to an embodiment of the present application.

[0029] As shown in Figure 1 in combination with Figure 2 and Figure 3 , the in-vehicle hair cutting device 2000 is integrated in the rear passenger seat 1100 of the vehicle 1000. The in-vehicle hair cutting device 2000 comprises a linkage mechanism 2100, a hair cutter 2200, and a control unit 2300. The control of the linkage mechanism 2100 by the control unit 2300 is schematically represented by dashed arrows in Figure 1 . As shown in Figure 3 schematically, the linkage mechanism 2100 adopts a three-linkage series configuration, which is compact in structure and designed for the limited space in the vehicle. In the example of the figures, the linkage mechanism 2100 comprises three links 2110, each of which is made of, for example, high-strength aluminum alloy material to ensure lightweight and structural strength. The adjacent links 2110 are connected through hinge points, each of which contains a high-precision bearing, allowing the three links 2110 to move with multiple degrees of freedom in three-dimensional space. The hair cutter 2200 is fixedly installed at the end execution site of the linkage mechanism 2100, and the hair cutter 2200 is, for example, a specially customized small electric trimmer equipped with an electric hair clipper with a precision ceramic cutter head, which is provided with a comb tooth protection cover with adjustable length. In Figure 3 the control unit 2300, which is, for example, a high-performance embedded computer system, is built into the central computing platform of the vehicle 1000 or inside the seat. The control unit 2300 can run a set of complex kinematics and dynamics algorithm software. After receiving the hair cutting instruction, the control unit 2300 can calculate the angles and speeds of rotation and movement required by each hinge point and link according to the preset program or real-time sensor data, and then drive the corresponding motor through electrical signals, thereby controlling the coordinated movement of the entire linkage mechanism 2100. Finally, the hair cutter 2200 is driven to move along a series of predetermined trajectories above the scalp of the passenger P to complete the precise trimming, thinning, or styling of the hair.

[0030] As shown in Figure 3As schematically shown, a camera 2700 is integrated at the end region of the linkage mechanism 2100, in close proximity to the hair cutter 2200. Specifically, the camera 2700 can be a structured light camera or a time-of-flight (ToF) camera. At the initial stage of the haircut procedure, the control unit 2300 can control the linkage mechanism 2100 to drive the camera 2700 to perform one or several scanning motions over the head of the passenger P. In this process, the camera 2700 can actively project a coded light fringe pattern (structured light) or infrared light pulses (ToF), and receive the reflected light through its photosensitive elements. The image processing module built in the control unit 2300 can analyze the distortion or time-of-flight difference of these reflected lights in real time, and thus calculate the spatial three-dimensional coordinates corresponding to each pixel point in the camera’s field of view. By stitching the data obtained from multiple scans, the control unit 2300 can quickly generate a dense point cloud containing millions of data points, which accurately depicts the three-dimensional contours of the head, face, ears, neck, and shoulders of the passenger P. This three-dimensional model is crucial for the subsequent haircut operation: first, it is used as a collision detection model, and the control unit 2300 can ensure that the cutter always maintains a safe distance from the model surface when planning the motion trajectory of the hair cutter 2200, avoiding any contact or injury. Second, the model provides the basis for the generation of the haircut path, and the system can plan a path on this digitized head that uniformly covers all the areas to be cut.

[0031] To ensure the cleanliness of the haircut process, the control unit 2300 can also be configured to control the linkage mechanism 2100 to perform a cleaning operation before or after the haircut procedure. For example, the linkage mechanism 2100 can be controlled to move the hair cutter 2200 to a position above the head of the passenger P, and then perform a cleaning operation by moving the hair cutter 2200 in a circular motion around the head of the passenger P. The cleaning operation can be performed by the hair cutter 2200 itself, or by a separate cleaning device (not shown) that is integrated with the hair cutter 2200. Figure 3As shown schematically, a suction device 2500 is integrated around the perimeter of the hair clipper 2200. Specifically, the main body of the suction device 2500 is an annular air scoop that surrounds the periphery of the clipper head 2200 with a small gap. The air scoop has an opening that faces the working area of the clipper head, i.e. where the hair is being cut. The air scoop is made of lightweight, transparent polycarbonate that provides an unobstructed view of the working area for the camera 2700, while being strong enough to withstand the forces. The back of the air scoop is connected to an air duct interface. Inside the linkage mechanism 2100, or along its outer wall, there is a lightweight, flexible, corrugated hose. One end of the hose is sealed to the air duct interface of the air scoop. The other end of the hose is connected to a small, high-efficiency centrifugal fan located in the trunk or under the seat of the vehicle. When the in-vehicle hair cutting system 2000 is activated, the control unit 2300 activates the fan at the same time. The fan spins at high speed, creating a strong negative pressure inside the hose and the air scoop. Air is sucked in through the opening of the air scoop, forming a powerful air current. When the blades of the hair clipper 2200 cut the hair, the hair clippings (long or short) are immediately captured by the air current and sucked into the air scoop, then transported through the hose to the collector 2600, which is located away from the passenger area.

[0032] Also as shown schematically, Figure 2 As shown schematically, the collector 2600 for collecting hair clippings can be placed in the trunk of the vehicle 1000. Specifically, it can be mounted in a specially designed recess in the side wall of the trunk, without occupying the main luggage storage space. The collector 2600 can be fixed to the vehicle body by a quick-release buckle, and the user can easily remove the entire collector by pressing a button or turning a handle. After removal, the user can open the lid, pour out the hair clippings inside, or directly replace the disposable dust bag inside. This arrangement has several significant advantages: first, it completely physically separates the waste collection area from the passenger compartment, avoiding any possible secondary pollution or odor; second, the trunk space is relatively abundant, allowing for a larger capacity collector that reduces the frequency of cleaning; finally, the cleaning operation is performed outside the vehicle, which is convenient and does not soil the interior.

[0033] In addition to the 3D camera for scanning the head geometry, the hair cutter 2200 can also be integrated with a macro HD camera (which can reuse the above camera or be a separate one) next to it, which is dedicated to determining the current hair length of the passenger P in real time. The working principle can be as follows: near the suction port of the suction device 2500 of the hair cutter 2200, a miniature auxiliary lighting source is provided. When the hair cutter 2200 moves to a certain to-be-measured area, the suction device 2500 can generate a precisely controlled air flow to gently suck up and straighten a small amount of hair in the area. At this time, the macro camera 2700 takes pictures of the straightened hair at a very high frame rate. The image recognition algorithm in the control unit 2300 can process these images in real time: first, the straightened hair is identified by edge detection and Hough transform and other techniques; second, the position of the hair root (i.e. the surface of the scalp) is determined using a known head three-dimensional model; then, the algorithm tracks the end of the hair and calculates the pixel length from the hair root to the hair tip; finally, the pixel length is accurately converted to a physical length of millimeter level by combining the calibration parameters of the camera and the known object distance. This process is repeated continuously as the hair cutter moves, thereby achieving dynamic and high-density measurement of the hair length on the entire head.

[0034] In a preferred embodiment, the control unit 2300 can provide a graphical user interface (UI) for the occupant P, which can be displayed on an OLED touchscreen mounted on the backrest of the front seat, for example. When the occupant activates the haircut function, a variety of preset hairstyles can be presented on the screen. Each hairstyle is accompanied by a high-definition effect picture, a 360-degree preview model, and a brief textual description. The occupant can click on the hairstyle of interest to enter the detail page for viewing more angles of presentation, or even virtually "try on" the hairstyle on his real-time image through the camera. In addition to the preset hairstyle library, the user interface can also provide a custom mode, allowing the occupant to adjust the hair retention length of different areas (such as the top of the head, the sides, and the back of the head) by dragging the sliders. All operations are completed through intuitive touch, swipe, and click, providing the occupant with a highly interactive and personalized selection experience. Alternatively, this user interface function can also be realized through a smartphone application (APP) developed specifically for this vehicle-mounted haircut device. When the occupant first uses it, the phone is paired and bound to the control unit 2300 of the vehicle through Bluetooth or vehicle-mounted Wi-Fi. Thereafter, the occupant can open the APP in advance anywhere (such as at home or in the office) to browse the cloud-based hairstyle library containing hundreds of hairstyles. This hairstyle library can be regularly updated by professional stylists. The occupant can not only collect favorite hairstyles but also use the built-in editing tools of the APP for deep customization: on a general three-dimensional head model, the desired length of different areas is "painted" by finger smearing, or the occupant's own photo is uploaded to let AI generate personalized hairstyle recommendations. After the design is completed, the hairstyle plan can be saved in the user's cloud account. When the occupant enters the vehicle and connects to the system, he / she only needs to click "Start haircut" in the APP, and the previously selected or designed hairstyle data can be wirelessly transmitted to the control unit 2300 of the vehicle 1000, and the vehicle-mounted haircut device 2000 starts working accordingly.

[0035] Figure 4 A schematic application scenario diagram of the vehicle-mounted haircut device 2000 for the vehicle 1000 according to an embodiment of the present application is shown.

[0036] As Figure 4The hollow arrow shows that the base of the linkage mechanism 2100 can move along the upper edge of the rear seat 1100 (for example, from the solid line position to the dashed line position), and this transverse movement capability enables the hair cutter 2200 to better adapt to the sitting position of different passengers P, whether the passenger P sits on the left, middle or right position of the rear seat, the vehicle-mounted hair cutting device 2000 can be adjusted to the best working position. The movement of the base can also help the hair cutter 2200 to cover different areas of the passenger's head, especially the difficult-to-reach positions such as the sides and the back, to ensure the comprehensiveness and uniformity of the haircut. This design also improves the adaptability of the vehicle-mounted hair cutting device 2000 to passengers P of different sizes, and through the adjustment of the base position, the positional deviation caused by individual differences such as height and sitting posture can be compensated. The design of moving the base also facilitates the storage of the vehicle-mounted hair cutting device 2000, which can move the base to the edge of the seat to maximize the use of space.

[0037] As Figure 4 As shown by the dotted box, in order to drive the linkage mechanism 2100 of the vehicle-mounted hair cutting device 2000 to move, a drive motor 2400 is provided inside (preferably for each hinge point). For example, a brushless direct current (BLDC) servo motor with high torque density and low noise can be used. The drive motor 2400 is equipped with a high-precision absolute value encoder for real-time feedback of the accurate rotation angle of the hinge point. The drive motor 2400 can be electrically connected to the motor driver module of the control unit 2300 through a shielded cable. The control unit 2300 sends pulse width modulation (PWM) signals or digital communication instructions (such as through an EtherCAT bus) to the corresponding motor driver according to the target angle, angular velocity and angular acceleration of each hinge point calculated by its motion planning algorithm. After receiving the instructions, the driver accurately controls the size and direction of the current supplied to the motor, thereby generating the required electromagnetic torque to drive the linkage 2110 to move smoothly and accurately according to the predetermined trajectory and speed. This distributed motor drive scheme enables independent and coordinated control of each hinge point, which is the key to achieving complex spatial motion trajectories. In addition, for safety reasons, the drive motor 2400 can also be integrated with an electromagnetic brake that can immediately lock the hinge point position in the event of power failure or emergency stop, preventing the linkage mechanism from falling due to gravity and ensuring the safety of the passenger P. In an alternative embodiment, the drive motor 2400 is configured as a stepper motor, which has the advantage of simple structure and relatively low cost compared to servo motors, and can achieve relatively high positioning accuracy without encoder feedback (i.e. open-loop control). In addition, the stepper motor has a self-locking torque (holding torque) when stationary, which helps to stabilize the linkage mechanism in a certain posture.

[0038] In a preferred embodiment, the control unit 2300 of the in-vehicle haircut device 2000 is connected to the navigation system of the vehicle 1000 via the controller area network bus or the in-vehicle Ethernet network. This connection enables the control unit 2300 of the in-vehicle haircut device 2000 to access the rich route information provided by the navigation system in real time. For example, when the vehicle 1000 is driving straight on a highway, the control unit 2300 of the in-vehicle haircut device 2000 can learn from the navigation system that the road ahead is flat and in good condition for the next 5 kilometers. In this ideal condition, the control unit 2300 can perform the haircut procedure with the highest efficiency and precision. However, when the route planned by the navigation system contains an upcoming sharp turn, a series of consecutive turns (e.g., a mountain road), or a region marked as a "bumpy road" by the map data, the navigation system can send these early warning information to the control unit 2300 of the in-vehicle haircut device 2000 in advance (e.g., 30 seconds or 500 meters in advance). Upon receiving this information, the control unit 2300 can immediately trigger the pre-set response strategy. For example, the movement speed of the linkage mechanism 2100 can be temporarily reduced to increase stability; or, before entering a very bumpy road section, the haircut operation can be completely suspended, and the hair clipper 2200 can be moved to a safe position away from the passenger's head, and then automatically resumed after the vehicle has passed the road section.

[0039] In another preferred embodiment, the control unit 2300 can establish a high-bandwidth communication connection with the driving data system responsible for collecting and processing vehicle dynamic information via the CAN bus of the vehicle. Through this connection, the control unit 2300 can access a series of key vehicle dynamic parameters in real time at a high frequency, including but not limited to: four-wheel wheel speed, steering wheel angle, yaw rate, longitudinal and lateral acceleration. The control unit 2300 may, for example, store a multi-dimensional safety threshold value. For example, when the lateral acceleration is detected to exceed 0.3g (indicating that the vehicle is making a sharp turn), or the longitudinal acceleration changes dramatically (indicating that the vehicle is accelerating or braking sharply), or the yaw rate exceeds 15 degrees per second, the current state can be immediately judged as "unsafe" and the interrupt mechanism can be triggered to suspend the haircut operation. Due to the complex and variable traffic conditions faced by the vehicle during driving, in some cases (such as high-speed lane changing, emergency avoidance, adverse weather, etc.), the stability of the vehicle is reduced or the driver needs to be highly focused, and continuing the haircut operation may pose a safety hazard: on the one hand, the shaking of the vehicle may cause accidental contact between the hair clipper and the passenger's head, causing injury; on the other hand, the operation of the in-vehicle haircut device may distract the driver (e.g., noise, visual interference, etc.). The automatic suspension function actively interrupts the haircut operation when it identifies pre-set high-risk situations by monitoring the vehicle and traffic conditions in real time, and the hair clipper quickly retreats to a safe position or remains stationary, eliminating potential dangers.

[0040] Therefore, the method of determining specific traffic conditions based on navigation routes, real-time speed, and traffic density data achieves a scientific and precise approach to safety judgment. By comprehensively analyzing the road condition information provided by the navigation system, it can anticipate complex road sections to be encountered, such as continuous curves, inclines, declines, and tunnels, and adjust haircutting strategies accordingly. Monitoring real-time speed data allows the system to identify dynamic changes in vehicles, such as sudden acceleration and deceleration, and respond promptly. Traffic density information helps the system assess the complexity of the surrounding traffic environment, suspending haircuts in situations of heavy traffic or frequent lane changes to reduce safety risks. This multi-dimensional data fusion analysis improves the accuracy and reliability of judgments, avoiding misjudgments that may be caused by a single indicator. Furthermore, the judgment model can be continuously optimized through machine learning algorithms, and the setting of safety thresholds can be improved based on historical data and user feedback. This data-driven safety strategy enables in-vehicle haircutting services to intelligently adapt to various road conditions, achieving an optimal balance between safety and service efficiency.

[0041] like Figure 3 As schematically shown by the dashed box, a electrically retractable headrest 1110 is also provided in the rear seat 1100 where the in-vehicle hair clipper 2000 is installed. The movement range and control logic of this headrest 1110 are compatible with the in-vehicle hair clipper 2000. In normal seating mode, the headrest 1110 is in the raised position (e.g., ...). Figure 3 (The location is schematically indicated by the dashed box), providing support and collision protection for the head of occupant P. When occupant P initiates the hair-cutting function, before the linkage mechanism 2100 extends, the control unit 2300 can first send a command to the seat control module, and the seat headrest 1110 will smoothly and completely retract into the seat back, leaving the necessary movement space for the hair clipper 2200 in its working area above it, allowing it to freely reach all areas of the head, including the top and back of the head. When the haircut is completed or paused midway, the seat headrest 1110 can automatically rise, restoring its support and protection functions.

[0042] In preferred embodiments, the in-vehicle haircut device 2000 can be applied to L3 or above autonomous driving vehicles, for example. The autonomous driving system is deeply integrated with the in-vehicle haircut device, sharing sensor data and computing resources. The vehicle’s lidar, millimeter wave radar, and cameras are used not only for autonomous driving but also provide all-around environmental perception for the in-vehicle haircut device. The path planning algorithm of the autonomous driving system can take into account the haircut requirements and choose a smoother route when possible. When the occupant chooses a haircut service, the autonomous driving system can automatically control the vehicle speed below 80 km / h and avoid aggressive acceleration, deceleration, and steering operations. The vehicle can dynamically adjust the driving strategy according to the progress of the haircut, such as appropriately reducing the vehicle speed when the haircut is close to completion to ensure the quality of the haircut. The redundant safety system of the autonomous driving system can also cover the in-vehicle haircut device, and any safety-related event will trigger an emergency stop of the in-vehicle haircut device. The V2X communication capability of the vehicle can obtain information about the road ahead and provide early warning of possible interruptions to the in-vehicle haircut device. In the fully autonomous driving mode, the driver in the front seat can also enjoy the haircut service. The AI assistant of the vehicle can intelligently recommend a haircut time according to the occupant’s schedule, such as automatically asking whether a haircut service is needed during a long commute. The in-vehicle haircut device, combined with the autonomous driving system, can also learn user preferences, record haircut experience evaluations under different road conditions, and continuously optimize service quality.

[0043] Although specific embodiments of the application have been described in detail herein, they are merely for the purposes of illustration and explanation and are not to be taken as limiting the scope of the application. Various substitutions, alterations and modifications can be conceived of by those skilled in the art without departing from the spirit and scope of the application.
