[0050] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0051] It should be noted that, unless otherwise specified, the technical or scientific terms used in the present disclosure should have the common meanings understood by those skilled in the art to which the present disclosure belongs.

[0052] With the development of the automobile industry, consumers' demands for automobile multimedia functions are becoming more and more diversified, and rear passengers' demand for infotainment functions is increasing. Passengers can conveniently conduct conference calls, watch TV series, study and work in the back seat, and help soothe the anxious emotions of crying children in the car. Compared with mobile phones, the rear screen is larger and less prone to motion sickness.

[0053] Typically, a tablet or screen is secured behind the driver's or co-driver's seat using a fixed bracket, which can be detachable or fixed. However, since the bracket is fixed to the seat, the distance between the screen and the front cannot be adjusted, which is very inconvenient.

[0054] To solve the above technical problems, the embodiments of the present disclosure propose a display module, a vehicle seat and a car, which can be extended and retracted under the drive of a drive motor, so that the front and rear distance of the screen can be adjusted as needed for easy use.

[0055] Example 1

[0056] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, a display module includes a drive motor 1, a linkage part 2, a display device 16 and a sliding part 3. The drive motor 1 is connected to the follower 4 through a connecting member 5, and the drive motor 1 can drive the follower 4 to perform circular motion; the linkage part 2 is provided with a slide groove 22, and the follower 4 is slidably connected in the slide groove 22; the display device 16 is connected to the linkage part 2; and the linkage part 2 is slidably connected to the sliding part 3.

[0057] The drive motor 1 serves as a power source and is responsible for providing the necessary driving force to drive the other components to operate. Specifically, the drive motor 1 can be fixed to the seat through the motor bracket 12. The drive motor 1 can be a DC motor, which is powered by DC power and has good speed regulation performance. It is suitable for occasions that require frequent starting, stopping or reversing. The drive motor 1 can also be an AC motor, such as a synchronous motor and an asynchronous motor. The asynchronous motor is also called an induction motor. It is the most commonly used type of AC motor and has the advantages of simple structure, low cost, and easy maintenance. It is suitable for most industrial and household appliances. More specifically, the drive motor 1 can be a servo motor, which is an actuator in a closed-loop control system that can accurately control position, speed and torque. The drive motor 1 can also be a stepper motor, which controls the rotation angle of the motor by inputting a pulse signal. For each pulse input, the motor will rotate a certain angle, which is suitable for occasions that require precise positioning.

[0058] Connector 5 is a mechanical component that connects the drive end of drive motor 1 and follower 4. It transmits the rotational motion of drive motor 1 to follower 4, enabling follower 4 to move along a predetermined path. Specifically, connector 5 can be a connecting rod, cam, or other structure capable of driving follower 4 to rotate about the center of drive motor 1. More specifically, connector 5 is provided with a connection interface, which is the portion used to connect to drive motor 1 or other mechanical components. Specifically, the connection interface can take the form of a threaded hole, keyway, pin hole, etc.

[0059] The follower 4 is a mechanical component that follows the motion path of the connector 5 driven by the drive motor 1, converting rotational motion into linear motion. Specifically, the follower 4 can be a roller follower 4, with one or more rollers mounted on a follower head. These rollers can be supported by bearings and roll on a track, reducing friction, improving service life, and increasing motion precision, making it suitable for high-speed and heavy-load applications. The follower 4 can also be a tip follower 4, with a pointed follower head such as a small ball or a sharp metal point. This has a small contact area, making it suitable for light-load and low-speed applications and enabling high-precision motion control. The follower 4 can also be a flat-bottom follower 4, with a flat follower head such as a flat metal surface. This provides a large contact area, making it suitable for medium-speed and medium-load applications and capable of withstanding large lateral forces. The follower 4 can also be a ball follower 4, with a small ball head made of a hard material. This provides a small contact area and low friction, making it suitable for high-precision and low-friction applications.

[0060] The linkage part 2 is a mechanical device used to connect and coordinate the movement of different mechanical parts to ensure that they work together in a predetermined manner, thereby converting the rotational movement of the drive motor 1 into the linear movement of the display device 16. Specifically, the linkage part 2 includes a linkage body 21 and a slide 22. The linkage body 21 can be an elongated strip or set to any shape according to the shape of the slide 22. The linkage body 21 has a simple structure and is easy to manufacture. It is suitable for straight or slightly curved motion paths and can achieve high-precision linear displacement. More specifically, the slide 22 is a straight line shape, which is simple and easy to manufacture, low in cost, and suitable for occasions requiring linear motion and can achieve high-precision linear displacement. The slide 22 can also be a curved shape, which can be an arc, a parabola, an ellipse, etc. The slide 22 can also be composed of multiple straight lines or curves, which is suitable for occasions requiring smooth transitions.

[0061] The display device 16 is an electronic device that converts electrical signals into visual images. These devices use various technologies and methods to convert digital or analog signals into optical signals, thereby displaying images or text on the screen. The display device 16 can be a standalone device or a component integrated into other devices. Specifically, the display device 16 can be an independent display screen, such as a liquid crystal display (LCD), a light-emitting diode display (LED), an organic light-emitting diode display (OLED), etc. The independent display screen can be connected to the vehicle controller to perform operations such as playing audio.

[0062] Display device 16 can also be an entire electronic device, such as a tablet computer, typically equipped with a touchscreen that allows users to operate the device by touching the screen. Tablet computers are lightweight and portable, suitable for mobile use. They feature touchscreen operation, strong interactivity, and integrate multiple sensors, such as accelerometers and gyroscopes. They also have a built-in battery for long battery life. Students and teachers can use tablet computers for learning and teaching, while business professionals can use them for document processing and meeting record-keeping. Users can watch videos, play games, and read e-books. Doctors and nurses can use tablet computers to access medical records and record patient information. Display device 16 can also be a smartphone, capable of making calls, sending text messages, and using social media. It can also watch videos, play games, and listen to music. It can also handle email, manage schedules, make online payments, and use map applications for navigation. The electronic device can also be a computer monitor, an output device connected to a computer host computer for displaying computer-generated images. It offers high display quality, a variety of resolutions, and sizes, from small portable monitors to large desktop monitors. It also features a rich interface and supports multiple connection methods. Computer monitors are used for document editing, data analysis, video editing, game display, and online course learning. The electronic device can also be a television, which is a device for receiving and displaying broadcast programs. Modern televisions usually also have smart functions. The display size is large, suitable for multiple viewers. It has a high-definition display and supports multiple resolutions. It has an integrated intelligent system and supports Internet connection and applications. It can watch movies, TV series, news, online courses, documentaries, etc. The display device 16 can also be an e-book reader, which is a device specifically used for reading e-books, usually using electronic ink technology. E-book readers have low power consumption, long battery life, do not flicker, are eye-friendly, light and portable, and suitable for long-term reading. E-book readers can read e-books, magazines, newspapers, textbooks, reference materials, etc.

[0063] The sliding part 3 is a mechanical device for supporting and guiding other components (such as the linkage part 2, the follower 4, etc.) to slide along a predetermined path, so that the display device 16 can be extended and retracted. Specifically, the sliding part 3 can be a linear guide rail, which is a device for supporting and guiding components to slide along a straight path. It has a simple structure, is easy to install, has smooth movement, low friction, and a strong load-bearing capacity, and is suitable for high-load applications. The sliding part 3 can also be a ball guide rail, which is a sliding device that uses balls as rolling bodies and is used to support and guide components to slide along a straight path. It has low friction, smooth movement, and high precision, and is suitable for high-precision applications. The sliding part 3 can also be a slider guide rail, which is a device that uses sliders as sliding bodies and is used to support and guide components to slide along a straight path. It has a simple structure, low cost, slightly higher friction, but is suitable for low-speed and light-load applications. The sliding part 3 can be a curved guide rail, which is a device for supporting and guiding components to slide along a curved path. Curved guide rails can achieve complex motion trajectories. The sliding portion 3 can also be a roller guide, a sliding device that uses rollers as rolling elements to support and guide components sliding along straight or curved paths. Roller guides offer low friction, smooth motion, and a high load-bearing capacity, making them suitable for high-load applications. The sliding portion 3 can also be an air guide, a sliding device that uses compressed air as a supporting medium to support and guide components sliding along straight paths. Air guides offer extremely low friction, very smooth motion, and high precision, making them suitable for ultra-high-precision applications.

[0064] like Figure 3 and Figure 4 As shown, the display module of the present disclosure utilizes a drive unit to rotate the connecting portion 7, thereby driving the follower 4. The follower 4 slides along the guide groove 22 or guide rail, converting the rotational motion into motion along the guide groove 22 and linear motion of the linkage portion 2 along the sliding portion 3. This in turn causes the display device to slide along the extension direction of the sliding portion 3, thereby achieving telescoping and adjusting the front-to-back distance of the screen. Furthermore, the drive unit and follower unit can be vertically positioned within the seat. The motor-driven sliding linkage portion 2 occupies less space than a drive method using an electric push rod or pneumatic cylinder, which can only be positioned horizontally. This also allows for high-precision motion control, ensuring that the display device 16 is accurately moved to a predetermined position.

[0065] In some modified embodiments of the present disclosure, the connecting member 5 is a connecting rod, one end of which is connected to the drive motor 1, and the other end of which is connected to the follower 4. The drive motor 1 is connected to one end of the connecting rod via a shaft or a coupling, and the other end of the connecting rod is connected to the follower 4. The follower 4 can be a roller follower 4 or other type of follower 4. The connecting rod has a simple structure, is relatively easy to maintain, and has a low failure rate.

[0066] Specifically, the connecting rod and follower 4 can be connected via a pin. This pin connection allows the follower 4 to rotate freely within a certain range while maintaining an effective connection to the connecting rod, making it suitable for applications requiring rotation or swinging. For connections that do not require relative rotation, a direct bolt connection can be used to connect the connecting rod and follower 4. This method is more stable but less flexible. When friction needs to be reduced or smooth movement of the follower 4 on the connecting rod is required, a bearing connection can be used. This connection method is suitable for high-precision or high-speed applications.

[0067] In some modified embodiments of the present disclosure, such as Figure 1 and 2 As shown, the connecting member 5 is a driving wheel, the center of which is connected to the driving motor 1, and the periphery of the driving wheel is connected to the follower 4. The driving motor 1 is directly connected to the center of the driving wheel through a shaft or a coupling, and the follower 4 is connected to the periphery of the driving wheel. The follower 4 can be a roller follower 4 or another type of follower 4. Specifically, the driving wheel can be a circular driving wheel, an elliptical driving wheel, and a polygonal driving wheel, among which the circular driving wheel is the most common shape, and the edge can be smooth or have teeth. The wheel-shaped structure is compact and has higher strength, and can transmit greater torque. Similarly, the driving wheel and the follower 4 can also be connected by pin connection, bolt connection, and bearing connection.

[0068] like Figure 1 and Figure 2 As shown, in some modified embodiments of the present disclosure, the sliding portion 3 includes a first guide rail 31, a second guide rail 32, and a third guide rail 33; the first guide rail 31, the second guide rail 32, and the third guide rail 33 are arranged in parallel in space, and the two ends of the linkage portion 2 are slidingly connected to the first guide rail 31 and the second guide rail 32, respectively, and one side of the linkage portion 2 is slidingly connected to the third guide rail 33. Specifically, the sliding portion 3 can be slidingly connected to the first guide rail 31, the second guide rail 32, and the third guide rail 33, respectively, through sliders. By means of three guide rails arranged in parallel, the linkage portion 2 can remain stable in multiple directions, reducing shaking and offset. The multi-guide rail system can provide higher motion accuracy, ensuring that the motion trajectory of the linkage portion 2 is accurate; by means of guide rails arranged in parallel, multi-directional motion control can be achieved in a limited space, saving space.

[0069] Specifically, the first and second guide rails 31 and 32 can be bolted to the actuator lower housing 37. The third guide rail 33 can be mounted to the actuator upper housing 35 using a guide rail bracket 34 and screws. The upper and lower housings 35 and 37 are bolted together on either side to the actuator front cover 38 and actuator rear cover 36. Together, the upper and lower housings 35, 37, front cover 38, and rear cover 36 form a relatively sealed actuator housing, protecting the follower 4 and guide rail structure within. More specifically, the guide rail bracket 34 is an L-shaped bracket, one side of which is bolted to the upper housing 35 and the other side to the rear cover 36, thereby connecting the upper and lower housings 35 and 37. The front cover 38 has an opening through which the linkage unit 2 can extend and retract.

[0070] In some modified embodiments of the present disclosure, the first guide rail 31 and the second guide rail 32 are positioned outside the travel range of the follower 4. This placement effectively prevents interference between the follower 4 and the guide rails, optimizing the system layout and improving its stability and reliability. Furthermore, it allows the follower 4 to rotate from the side closest to the display device 16 to the side farther away from the display device 16, allowing the linkage portion 2 to retract over a wider range and further reducing the lateral space occupied.

[0071] like Figure 1 As shown, in some modified embodiments of the present disclosure, the display module further comprises a support arm 6, a connecting portion 7, and a fixing portion 8. One end of the support arm 6 is connected to the linkage portion 2, one side of the connecting portion 7 is connected to the other end of the support arm 6 via a torque hinge 14, the fixing portion 8 is connected to the other side of the connecting portion 7, and the display device 16 is mounted on the fixing portion 8. The addition of the support arm 6, the connecting portion 7, and the fixing portion 8 enables the entire system to not only achieve precise sliding motion but also, through the cooperation of the support arm 6 and the connecting portion 7, achieve multi-degree-of-freedom adjustment of the display device 16.

[0072] The support arm 6 can be in a straight shape, usually a straight rod, a straight plate or a tubular structure. For example, it can be a single-rod straight support arm 6, which has a simple structure and low cost, and is suitable for light loads and single-direction adjustments. It can also be a double-rod straight support arm 6, which is composed of two parallel straight support arms 6, and can provide higher stability and load-bearing capacity. The support arm 6 can also be a single-section telescopic support arm 6, which is telescopically adjustable through one or more sleeves and can adjust the length, and is suitable for occasions requiring large-stroke adjustment. The support arm 6 can also be a multi-section telescopic support arm 6, which is telescopically adjustable through multiple sleeves, and can achieve a larger adjustment range and higher stability. By setting a single-section telescopic support arm 6, the user can directly manually adjust the position of the electric equipment according to their usage requirements.

[0073] The linkage portion 2 and the support arm 6 can be fixedly connected in a variety of ways, such as welding, bolting, riveting, or by means of positioning posts. Specifically, a plurality of positioning posts can be provided on the top of the support arm 6, and a plurality of positioning holes can be provided on the linkage portion 2, with the positioning holes and the positioning posts cooperating. A support arm cover 13 is also provided on the top of the linkage portion 2. The support arm cover 13 is fixedly connected to the support arm 6, that is, a portion of the structure of the linkage portion 2 is sandwiched between the support arm 6 and the support arm cover 13, thereby further securing the linkage portion 2.

[0074] The connecting portion 7 refers to a component used to connect the fixing portion 8 and the support arm 6 and allow relative movement between these components. Specifically, the main body of the connecting portion 7 can be a plate-like structure or a disc-like structure to reduce its thickness and occupy space. The torque hinge 14 is a hinge that can provide a certain resistance, so that the connecting portion 7 can rotate or tilt freely within a certain range while maintaining the angle selected by the user and will not change its position arbitrarily due to factors such as gravity. More specifically, the outer side of the connecting portion 7 can be provided with a back cover to protect the connecting portion 7.

[0075] The fixing portion 8 is a component for fixing the display device 16. Specifically, the fixing portion 8 can be a shell 71 with an opening on one side, and the display device 16 can be clipped into the fixing portion 8. The fixing portion 8 can also be a bracket, which is fixedly connected to the display device 16. The fixing portion 8 can also be a suction cup, so as to fix the display device 16 on a smooth surface. The fixing portion 8 can also be a quick-release plate, which allows the display device 16 to be quickly installed and removed, making it convenient to replace or adjust the position. As long as the fixing portion 8 can fix the display device 16, there is no specific limitation on the structure and type of the fixing portion 8.

[0076] In some modified embodiments of the present disclosure, the connecting portion 7 includes a shell 71 and a magnet 73. The hinged end of the shell 71 is connected to the other end of the support arm 6 via a torque hinge 14. The magnet 73 is disposed in the shell 71, and the magnet 73 and the fixing portion 8 are magnetically connected, thereby making the fixing portion 8 detachable. The magnetic connection between the magnet 73 and the fixing portion 8 provides a reliable fixing effect, ensuring that the display device 16 remains stable during use. The magnetic connection method makes the installation and removal of the display device 16 quick and easy, making it convenient for users to adjust or replace it. The design of the shell 71 can be coordinated with the overall style of the display device 16 to enhance the overall aesthetics.

[0077] The hinged end of the shell 71 can be directly connected to the torque hinge 14. Specifically, two opposite protrusions can be provided on one side of the hinged end of the shell 71 to form a hinged end, and the torque hinge 14 is installed on the two hinged ends. The hinged end of the shell 71 can also be indirectly connected to the torque hinge 14. Specifically, the connecting part 7 also includes a connecting part main body 72, and the connecting part main body 72 can be a plate-shaped structure or a disc-shaped structure to reduce its thickness and occupied space. Two opposite protrusions can be provided on one side of the connecting part main body 72 to install the rotating shaft of the torque hinge 14. The shape of the shell 71 is adapted to the shape of the main body to protect the main body, that is, two opposite hollow protrusions are provided on one side of the hinged end of the shell 71 to be sleeved on the outside of the main body protrusion. The rotating shaft of the torque hinge 14 passes through the two opposite protrusions of the connecting part main body 72 and is connected to the hollow protrusion.

[0078] The magnet 73 can be directly magnetically connected to the fixing part. For example, if the fixing part is made of iron material, the magnet 73 is directly magnetically attracted to the fixing part. The magnet 73 can also be directly magnetically connected to the fixing part. Specifically, a magnetic part 10 is provided on one side of the fixing part 8. A magnetic cover 9 is provided on the outer side of the magnetic part 10. The magnetic cover 9 is fixedly connected to the fixing part 8 through a connector to fix the magnetic part 10 to one side of the fixing part 8. The shell 71 may include a front cover 712 of the connecting part and a rear cover 711 of the connecting part. The magnet 73 is fixedly connected to the side of the front cover 712 of the connecting part close to the fixing part. The front cover 712 of the connecting part and the rear cover 711 of the connecting part are respectively provided on both sides of the connecting part body 72 to form a body that wraps the connecting part body 72. The hinged end of the shell 71 can be provided on the rear cover 711 of the connecting part.

[0079] In some modified embodiments of the present disclosure, the connecting portion 7 further includes a buckle 74, and the fixing portion 8 further includes a slot. The buckle 74 is mounted on the housing 71, and the buckle 74 and the slot cooperate. The buckle 74 is a mechanical device that secures the two components together through elastic deformation, and the slot is a groove or hole that cooperates with the buckle 74. The combination of the slot and buckle 74 provides an additional locking mechanism, ensuring a more secure connection between the connecting portion 7 and the fixing portion 8.

[0080] The slot can be directly provided on the fixing portion 8, with the buckle 74 mounted on the side of the housing 71 near the fixing portion 8. The buckle 74 and the slot engage to achieve the desired connection. Specifically, a one-way buckle 74 can be provided with the slot. The one-way buckle 74 can only be inserted into the slot. This is typically used to prevent misoperation and resists loosening after insertion, making it suitable for applications requiring long-term securement. A two-way buckle 74 can also be provided with the slot. The two-way buckle 74 can be inserted into the slot from both directions, providing greater installation flexibility. An elastic buckle 74 can also be provided with the slot. The elastic buckle 74 secures the component in the slot through elastic deformation, providing a certain self-locking function. The user only needs to press lightly to complete installation, making operation simple and quick. The user can easily remove the component by pressing or pulling, facilitating maintenance and replacement. An insertable buckle 74 can also be provided with the slot. The insertable buckle 74 secures the component 8 by directly inserting into the slot. No additional tools are required; the user simply inserts the buckle 74 into the slot to secure the component.

[0086] Example 3

[0087] A car includes a car seat and a controller. The car seat includes a seat body 17 and a display module; the display module includes a drive motor 1, a linkage part 2, a display device 16 and a sliding part 3. The drive motor 1 is connected to the follower 4 through a connector 5, and the drive motor 1 can drive the follower 4 to perform circular motion; the linkage part 2 is provided with a slide groove 22, and the follower 4 is slidably connected in the slide groove 22; the display device 16 is connected to the linkage part 2; the linkage part 2 is slidably connected to the sliding part 3; wherein, the display module is installed on the seat body 17, and the controller is connected to the drive motor 1.

[0088] In some modified embodiments of the present disclosure, a collision sensor and an acceleration sensor are further included, and the collision sensor and the acceleration sensor are connected to the controller; the controller can obtain the driving information of the vehicle from the collision sensor and the acceleration sensor, and determine whether the vehicle is in emergency braking or collision based on the driving information of the vehicle. If the vehicle is in emergency braking or collision, the controller obtains the retraction control parameters of the rear-seat tablet computer on the vehicle, and controls the drive motor 1 to rotate according to the retraction control parameters to retract the display device 16.

[0089] Specifically, a collision sensor is a sensor that can detect whether a vehicle has collided and can be installed at the front and rear of the vehicle. When the vehicle collides, the collision sensor will immediately send a signal to the controller. Specifically, the collision sensor can be a mechanical collision sensor, which detects collisions through changes in the mechanical structure. For example, a ball-type sensor and a spring-type sensor. The ball-type sensor has a ball inside. When the vehicle collides, the ball moves and triggers a switch. The spring-type sensor has a spring inside. When the vehicle collides, the spring deforms and triggers a switch. The collision sensor can also be an electronic collision sensor, which detects collisions through changes in electronic components. Specifically, it can be a piezoelectric sensor, a resistive sensor, and a capacitive sensor.

[0090] An accelerometer is a sensor that detects changes in vehicle acceleration. It can be installed in the center of the vehicle. When the vehicle experiences emergency braking or sudden acceleration, the accelerometer detects the change in acceleration and sends the data to the controller. Specifically, accelerometers can be MEMS (micro-electromechanical systems), piezoelectric, or resistive.

[0091] The controller is the core component of the system, responsible for processing data from the collision sensors and accelerometers and making decisions based on pre-set logic. The controller can acquire data, namely, obtain vehicle driving information from the collision sensors and accelerometers, and perform data analysis to determine whether the vehicle has experienced emergency braking or a collision. It can also issue control commands. If emergency braking or a collision is detected, the controller obtains the retraction control parameters of the in-vehicle rear-seat tablet computer and sends control instructions to the drive motor 1. Specifically, the controller can be a built-in controller in the vehicle, or it can be a microcontroller, programmable logic controller, embedded computer, etc.

[0092] During normal driving, the collision sensor and accelerometer continuously monitor the vehicle's status, and the controller continuously receives and analyzes sensor data. In the event of an emergency, the accelerometer detects a sudden change in vehicle acceleration exceeding a preset threshold, or the collision sensor detects a collision exceeding a preset threshold. Upon receiving the sensor signals, the controller immediately initiates the emergency procedure. Based on the sensor data, the controller determines whether the vehicle has experienced emergency braking or a collision. If an emergency is detected, the controller obtains the retraction control parameters for the vehicle's rear-seat tablet computer and sends a control command to drive motor 1, which begins rotating, driving the mechanical structure to retract display device 16 to a safe position.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
