[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] It should be understood that the phrase "some embodiments" throughout the specification means that a specific feature, structure, or characteristic related to an embodiment is included in at least one embodiment of this application. Therefore, "some embodiments" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0029] The following detailed description of a display screen locking mechanism, display screen assembly, and vehicle provided in this application is illustrated with specific embodiments.

[0030] This application provides a display screen locking mechanism, referring to... Figure 1 and Figure 2 As shown, the display screen locking mechanism includes: a housing 1 and a locking member 2, a first magnetic member 3, and a second magnetic member 4 disposed within the housing 1; the locking member 2 is movably connected to the housing 1, and a portion of the locking member 2 extends out of the housing 1 for connection with the display screen; the first magnetic member 3 extends along a first direction X, and has a first end 31 and a second end 32 disposed opposite to each other along the first direction X, the first end 31 is fixedly connected to the housing 1, and the second magnetic member 4 is disposed on the side where the second end 32 is located and is fixedly connected to the locking member 2; wherein, a coil 5 is wound on the first magnetic member 3 or the second magnetic member 4, and when the coil 5 is energized, the second magnetic member 4 moves relative to the first magnetic member 3, and drives the locking member 2 to move relative to the housing 1.

[0031] Specifically, the display screen locking mechanism of this embodiment can lock displays located on the vehicle roof, seats, etc. These displays can typically be folded or hidden inside the vehicle when not in use to avoid occupying interior space and provide a spacious environment for occupants. When in use, the displays are flipped to their operating position for entertainment, work, etc. If the display screen locking mechanism is located on the vehicle roof, then... Figure 1 and Figure 2 This is a simplified plan view from inside the vehicle towards the roof. If the display screen locking mechanism is located on the vehicle seat, then... Figure 1 and Figure 2 This is a simplified plan view from the rear seat of the vehicle towards the front seat.

[0032] The display screen locking mechanism includes a housing 1 and a locking member 2 disposed within the housing 1. The housing 1 is installed and fixed to the roof or seat of a vehicle by means of assembly connection, limit snap-fit, adhesive connection, etc. The housing 1 can be made of low-density, lightweight plastic, alloy, or some composite materials, possessing good strength and rigidity, and can provide good protection and support for the various components within the housing 1. The locking member 2 is disposed within the housing 1 and is movably connected to the housing 1. For example, one or more slide rails can be provided within the housing 1, and the locking member 2 is slidably connected to the slide rails; a rotating part can also be provided within the housing 1, and the locking member 2 is rotatably connected to the rotating part. This embodiment does not limit the specific method of movable connection between the locking member 2 and the housing 1.

[0033] The locking component 2 extends out of the housing 1 and is used to connect with the display screen. When the display screen is not in use and needs to be folded or hidden inside the vehicle, the locking component 2 needs to be engaged with the display screen to prevent it from not being fully folded and to prevent the display screen from being bumped or damaged during vehicle bumps or shaking. Of course, when the display screen is folded to the use position, it can also be locked to fix the display screen in the use position and prevent the display screen from shaking during driving, which would affect the user experience of the passengers.

[0034] In practical applications, a connection hole adapted to the locking member 2 can be provided on the display screen. For example, if the locking member 2 is a cylindrical shaft structure, a cylindrical hole can be opened on the display screen, and the locking member 2 is inserted into the cylindrical hole to realize the connection between the locking member 2 and the display screen. The locking member 2 can be a cylindrical shaft structure, a square shaft structure, or a shaft structure of other shapes. Correspondingly, a cylindrical hole adapted to its shape and structure can be provided on the display screen. It can be flexibly set in practical applications, and this embodiment does not limit it.

[0035] In the prior art, the display screen locking mechanism usually uses a multi-stage gear and rack transmission to drive the locking member 2 to extend or retract relative to the housing 1, so as to realize the locking member 2 and the display screen to lock or unlock. However, the mechanism requires a large number and variety of parts, resulting in a complex overall structure. It also requires a dedicated drive unit to drive the gear and rack to ensure the smooth operation of the locking member 2. This results in high control costs and low economic benefits.

[0036] In this embodiment, the display screen locking mechanism further includes a first magnetic element 3 and a second magnetic element 4 disposed within the housing 1. The first magnetic element 3 extends along a first direction X and has a first end 31 and a second end 32 disposed opposite to each other along the first direction X. The first end 31 of the first magnetic element 3 is fixedly connected to the housing 1. The first end 31 of the first magnetic element 3 can be fixed to the housing 1 by means of assembly connection, limiting snap-fit, adhesive connection, welding, etc. The specific connection method is not limited in this embodiment. The second magnetic element 4 is disposed on the side where the second end 32 of the first magnetic element 3 is located and is fixedly connected to the locking element 2. The second magnetic element 4 can be fixed to the locking element 2 by means of assembly connection, limiting snap-fit, adhesive connection, welding, etc. The specific connection method is not limited in this embodiment.

[0037] A coil 5 is wound around the first magnetic component 3 or the second magnetic component 4. When the coil 5 is energized, current flows through it. According to Ampere's law, a magnetic field is induced around the first magnetic component 3. One of the first end 31 and the second end 32 of the first magnetic component 3 induces a North pole (N pole), and the other induces a South pole (S pole). Based on the principle that like poles repel and unlike poles attract, the second magnetic component 4 will move relative to the first magnetic component 3. Since the second magnetic component 4 is fixedly connected to the locking component 2, its movement will cause the locking component 2 to move synchronously, thus moving the locking component 2 relative to the housing 1 and enabling the locking component 2 to extend or retract. Figure 1 and Figure 2 The diagram illustrates a configuration where a coil 5 is wound around a first magnetic element 3, in which the first magnetic element 3 serves as the active driving component. Alternatively, a coil 5 is wound around a second magnetic element 4, in which case the second magnetic element 4 serves as the active driving component. The first magnetic element 3 can utilize a ferrite core with a cylindrical structure to facilitate the winding of the coil 5 and reduce the likelihood of coil breakage. The second magnetic element 4 can also be a ferrite magnet, which helps control the material costs of both the first and second magnetic elements 3 and 4.

[0038] Figure 1 This diagram illustrates a locking member 2 in an extended state according to an embodiment of this application. (Refer to...) Figure 1As shown, when the locking member 2 is in the extended state, the second magnetic member 4 is attracted to the position close to the second end 32 of the first magnetic member 3 under the action of the magnetic field. The part of the locking member 2 located outside the housing 1 has a longer length in the first direction X, which facilitates the locking member 2 to cooperate with the connection hole on the display screen to achieve locking. Figure 2 This diagram illustrates a locking member 2 in a retracted state according to an embodiment of this application. (Refer to...) Figure 2 As shown, when the locking member 2 is in the retracted state, the second magnetic member 4 is pushed away from the second end 32 of the first magnetic member 3 under the action of the magnetic field. The part of the locking member 2 outside the housing 1 has a shorter length in the first direction X. In this state, the locking member 2 is disengaged from the connection hole of the display screen, thus unlocking.

[0039] Therefore, in the display screen locking mechanism of this application embodiment, a coil 5 is wound around the first magnetic component 3 or the second magnetic component 4. The magnetic field generated by energizing the coil 5 causes the second magnetic component 4 to move relative to the first magnetic component 3. Since the second magnetic component 4 is fixedly connected to the locking component 2, the second magnetic component 4 will drive the locking component 2 to move synchronously, causing the locking component 2 to extend or retract relative to the housing 1. When the locking component 2 is extended relative to the housing 1, it can cooperate with the display screen to lock and fix the display screen. When the locking component 2 is retracted relative to the housing 1, the cooperation between the locking component 2 and the display screen is released, thereby unlocking the display screen. Compared with the prior art, the display screen locking mechanism of this application embodiment significantly reduces the number and types of components configured in the mechanism, simplifies the overall structure, and the movement of the locking component 2 can be driven by energizing the coil 5, without the need for an additional drive unit, effectively reducing the control cost of the locking mechanism and helping to improve the economic efficiency of the product.

[0040] Optionally, refer to Figure 1 and Figure 2 As shown, in some embodiments of this application, the projection of the first magnetic element 3 in the first direction X is located within the projection of the second magnetic element 4 in the first direction X; or, the projection of the second magnetic element 4 in the first direction X is located within the projection of the first magnetic element 3 in the first direction X.

[0041] Specifically, setting the projection of the first magnetic element 3 in the first direction X to fall within the projection of the second magnetic element 4 in the first direction X, or vice versa, helps improve the coaxiality of the first magnetic element 3 and the second magnetic element 4 in the first direction X. Since the magnetic field strength distribution generated around the first magnetic element 3 when the coil 5 is energized is such that the magnetic field strength is greater closer to the center of the first magnetic element 3 and gradually decreases further away from the center, improving the coaxiality of the first magnetic element 3 and the second magnetic element 4 in the first direction X correspondingly enhances the interaction between them. This allows the first magnetic element 3 to provide sufficient driving force for the second magnetic element 4, further facilitating the attraction or movement of the second magnetic element 4, thus ensuring the smooth movement of the locking element 2.

[0042] Optionally, refer to Figure 1 and Figure 2 As shown, in some embodiments of this application, the display screen locking mechanism further includes: an elastic member 6; the elastic member 6 is disposed on the side where the second end 32 is located and extends along the first direction X; one end of the elastic member 6 along the first direction X is connected to the second magnetic member 4 or the locking member 2, and the other end of the elastic member 6 along the first direction X is connected to the housing 1.

[0043] Specifically, the elastic element 6 is located on the side where the second end 32 of the first magnetic element 3 is located. The elastic element 6 can be a helical spring, which extends along the first direction X. When the locking element 2 covers the second magnetic element 4, one end of the elastic element 6 along the first direction X is connected to the locking element 2. When the locking element 2 does not cover or does not completely cover the second magnetic element 4, one end of the elastic element 6 along the first direction X can be connected to both the locking element 2 and the second magnetic element 4. The other end of the elastic element 6 along the first direction X is connected to the housing 1. The connection between the elastic element 6 and the locking element 2 or the second magnetic element 4, as well as the housing 1, can be achieved by assembly connection, limiting snap-fit, adhesive connection, or contact pressing. This embodiment does not limit the specific connection method of the elastic element 6.

[0044] Reference Figure 1As shown, when the locking member 2 is in the extended state, the second magnetic member 4 is attracted to the position near the second end 32 of the first magnetic member 3 under the magnetic field. In this state, the elastic member 6 is not subject to external force and is in a freely extended state, and the display screen is locked and fixed. When the locking member 2 is in the retracted state, the second magnetic member 4 is pushed to the position away from the second end 32 of the first magnetic member 3 under the magnetic field. In this state, the elastic member 6 is squeezed and is in a compressed state, and the display screen is unlocked. When the current on the coil 5 decreases or the coil 5 is de-energized, the squeezing force on the elastic member 6 decreases or disappears accordingly. The elastic member 6 returns to its original shape under its own elasticity and drives the locking member 2 to move, so that the locking member 2 returns to the extended state and continues to maintain the locking and fixing of the display screen.

[0045] Of course, in some embodiments, the elastic element 6 can also be configured to be compressed when the locking element 2 is in the extended state, and to be freely extended when the locking element 2 is in the retracted state. In practical applications, the installation position of the elastic element 6 can be flexibly set, and this embodiment does not limit this.

[0046] In this embodiment, the elastic element 6 allows the coil 5 to receive only unidirectional current. The magnetic field generated by the energized coil 5 causes the locking element 2 to retract, and the elastic element 6 causes the locking element 2 to extend. Alternatively, the magnetic field generated by the energized coil 5 causes the locking element 2 to extend, and the elastic element 6 causes the locking element 2 to retract. This makes the function of the display screen locking mechanism more complete and its operation more reliable.

[0047] Optionally, in some embodiments of this application, the display screen locking mechanism further includes: a current commutation device; the current commutation device is electrically connected to the coil 5, and the current commutation device is used to change the direction of current flow in the coil 5. Specifically, the current commutation device can be a control chip, which can be disposed inside or outside the housing 1. The control chip is electrically connected to the coil 5 and can change the direction of current flow in the coil 5.

[0048] When the current flow direction changes, the direction of the magnetic field induced by the first magnetic element 3 also changes, thus altering the effect of the first magnetic element 3 on the second magnetic element 4. For example, if the first magnetic element 3 originally attracted the second magnetic element 4, causing the locking element 2 to extend, a change in the current flow direction in the coil 5 would cause the first magnetic element 3 to push the second magnetic element 4, causing the locking element 2 to retract. Conversely, if the first magnetic element 3 originally pushed the second magnetic element 4, causing the locking element 2 to retract, a change in the current flow direction in the coil 5 would cause the first magnetic element 3 to attract the second magnetic element 4, causing the locking element 2 to extend. Therefore, this embodiment, through the use of a current commutation device, can simultaneously control the extension and retraction of the locking element 2, achieving complete functionality of the locking mechanism.

[0049] In addition, the display screen locking mechanism may include both a current commutation device and an elastic element 6 to provide dual protection and further improve the reliability of the movement of the locking element 2.

[0050] Optionally, refer to Figure 1 and Figure 2 As shown, in some embodiments of this application, the display screen locking mechanism further includes: a controller and a position detection device 7; the position detection device 7 is located on the side where the second end 32 is located and is fixedly connected to the housing 1; the position detection device 7 is used to detect the movement position of the locking member 2 and generate a positioning signal when the locking member 2 moves to the target position; the controller is electrically connected to the position detection device 7 and is used to receive the positioning signal and control the current of the coil 5 to decrease or control the coil 5 to be de-energized when the positioning signal is received.

[0051] Specifically, the position detection device 7 can be a contact position sensor, such as a linear displacement sensor, or a non-contact position sensor, such as a photoelectric sensor, laser sensor, ultrasonic sensor, magnetic sensor, etc. All of these components can detect the movement position of the locking member 2. In this embodiment, the position detection device 7 uses a contact position sensor. When the locking member 2 moves to contact the contact position sensor, the position detection device 7 generates a positioning signal, which helps to ensure the accuracy of the signal generation.

[0052] The position detection device 7 generates a positioning signal when the locking member 2 moves to the target position. The target position refers to both the position where the locking member 2 extends to near its limit and the position where it retracts to near its limit; the specific position can be flexibly set according to different locking requirements. When the locking member 2 moves to the target position, the position detection device 7 sends a positioning signal to the controller, which is an electrical signal. Upon receiving the positioning signal, the controller reduces the current in the control coil 5 or de-energizes the control coil 5 to reduce or eliminate the magnetic field effect. When the magnetic field effect is reduced, the movement speed of the locking member 2 decreases until the magnetic field effect disappears, at which point the locking member 2 stops moving. When the magnetic field effect disappears, the locking member 2 may still have a slight movement due to inertia before finally stopping.

[0053] Optionally, refer to Figure 1 and Figure 2As shown in some embodiments of this application, the locking member 2 includes a main body 21 and a mounting part 22 connected to each other. The main body 21 extends along a first direction X and is movably connected to the housing 1. The mounting part 22 extends along a direction intersecting the first direction X, and the second magnetic member 4 is fixedly connected to the mounting part 22. Specifically, the locking member 2 can be a single piece manufactured by an integral molding process. The main body 21 and the mounting part 22 are different parts of the locking member 2. The main body 21 extends along the first direction X, which facilitates the locking member 2 to extend or retract relative to the housing 1 along the first direction X. The mounting part 22 extends along a direction intersecting the first direction X. The mounting part 22 can be perpendicular to the main body 21 or form a certain angle with the main body 21. Specifically, it can be flexibly set according to the space inside the housing 1, and this embodiment does not limit this. The second magnetic member 4 is fixedly connected to the mounting part 22, so that the locking member 2 moves relative to the housing 1 as a whole through the force received by the mounting part 22.

[0054] Optionally, refer to Figure 1 and Figure 2 As shown, in some embodiments of this application, the mounting part 22 is provided with a mounting groove, and at least a portion of the second magnetic element 4 is embedded and fixed in the mounting groove. The mounting groove can limit the position of the second magnetic element 4, improve the connection reliability between the second magnetic element 4 and the locking element 2, and also protect the second magnetic element 4, preventing damage to the surface of the second magnetic element 4 caused by collisions with the first magnetic element 3 or the housing 1 during long-term use, thereby helping to extend the service life of the second magnetic element 4. It should be noted that the second magnetic element 4 can be partially embedded in the mounting groove or completely embedded in the mounting groove, as long as the second magnetic element 4 can move under the magnetic field of the first magnetic element 3.

[0055] Optionally, in some embodiments of this application, a guide groove 10 is provided inside the housing 1, the guide groove 10 extending along the first direction X, and a portion of the main body 21 is disposed within the guide groove 10. Specifically, Figure 3 This diagram illustrates a configuration of the main body 21 and guide groove 10 in an embodiment of this application. (Refer to...) Figure 3 As shown, the guide groove 10 can be provided on the top wall and bottom wall of the housing 1, and the space between the top wall and bottom wall is the side wall of the housing 1. The first magnetic element 3 is connected to the side wall of the housing 1. The main body 21 of the locking element 2 is provided with a protrusion 210 that is adapted to the guide groove 10. The protrusion 210 is embedded in the guide groove 10. The guide groove 10 extends along the first direction X. The guide groove 10 can guide and limit the movement of the main body 21, so as to further improve the stability of the locking element 2 in the process of extending or retracting relative to the housing 1.

[0056] This application also provides a display assembly, including a display body and a display locking mechanism as described in any of the preceding claims. The display body includes a frame and a screen disposed within the frame. The frame has a connection hole, and the locking member 2 in the display locking mechanism is engaged with the connection hole. Specifically, the shape and structure of the connection hole and the locking member 2 are adapted to each other. When the locking member 2 extends out of the housing 1, it engages with the connection hole to lock and fix the display body. When the locking member 2 retracts into the housing 1, it disengages from the connection hole, thereby unlocking the display body.

[0057] This application also provides a vehicle including the aforementioned display assembly. The display assembly can be installed on the roof of the vehicle or on the seat of the vehicle. The display assembly has a simple structure and low control cost, which is conducive to the optimization and improvement of the vehicle.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device.
