[0059] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0060] Combine the following Figures 1 to 13 , describing a vehicle display screen device, a display screen fixing method and a vehicle according to an embodiment of the present invention.

[0061] According to an embodiment of the present invention, on the one hand, a display screen device for a vehicle is provided, which is suitable for use in automobiles, low-altitude aircraft, etc. The display screen device for a vehicle includes a fixing frame assembly 1, a display screen 2, a locking structure 20, and a control module (not shown in the figure). Taking a car as an example, the display screen 2 can be used as a display device such as a central control display screen, a liquid crystal instrument panel, a co-pilot and rear seat entertainment screen, etc. of the car. Specifically, the central control display screen with the highest usage rate in the vehicle is taken as an example to illustrate this embodiment. Figures 1 to 3 As shown, the fixing frame assembly 1 is provided with a carrier connection portion 101 and a display screen connection portion 102, the carrier connection portion 101 is connected to the instrument panel 16, and the back 201 of the display screen 2 is connected to the display screen connection portion 102 via a quick release structure 17. In this way, the user can quickly remove and install the display screen 2, which is convenient for the user to operate.

[0062] like Figure 5 and Figure 6As shown, the locking structure 20 is used to lock or release the display screen 2 and the display screen connection part 102. The control module is electrically connected to the locking structure 20, and the control module is used to control the locking structure 20 to lock the display screen 2, or release the display screen 2. Specifically, the control module can be set independently or integrated in the vehicle control system, and the locking structure 20 and the control module can be electrically connected through the wiring harness 13. In this way, during driving, such as when driving at high speed, the control module controls the locking structure 20 to lock the display screen 2. At this time, the lock can be forced to open to prevent the display screen 2 from being removed. If driving at a low speed, the control module controls the locking structure 20 to release the display screen 2. At this time, the user can choose whether to remove the display screen 2 according to the needs. It can be understood that the above application scenarios are not limited to high and low speed driving states, and can also be selected according to the environment and location of the vehicle, such as urban traffic roads or outdoor camping sites, etc., to choose whether to lock the display screen 2 to meet the user's usage needs and improve the user's riding experience.

[0063] With such a configuration, the fixing frame assembly 1 can be installed on the vehicle, and the quick-release structure 17 can be used to quickly remove and install the display screen 2, which is convenient for users to operate and use, and easy to maintain. At the same time, during the driving of the vehicle, according to the actual application requirements such as the vehicle condition, the control module can control the locking structure 20 to lock or release the display screen 2, so that the display screen 2 can be firmly fixed on the fixing frame assembly 1, preventing the passengers from removing the display screen 2 at will, ensuring that the driver can obtain navigation information, vehicle status, etc. through the display screen 2 in a timely manner, eliminating safety hazards, and ensuring driving safety and personal safety.

[0064] Further, see Figure 5 and Figure 6 In some embodiments of the present invention, the locking structure 20 includes an electromagnet 3 and a magnet 4 that attract each other. The control module is electrically connected to the electromagnet 3, and the control module is used to control the electromagnet 3 to be energized or de-energized, so as to lock the display screen 2 or release the display screen 2.

[0065] In this embodiment, one of the display screen 2 and the display screen connection part 102 is provided with an electromagnet 3, and the other is provided with a magnet 4. That is, the display screen 2 is provided with an electromagnet 3, and the display screen connection part 102 is correspondingly provided with a magnet 4. Alternatively, the display screen connection part 102 is provided with an electromagnet 3, and the display screen 2 is correspondingly provided with a magnet 4. It can be understood that the magnet 4 refers to a substance or material with magnetism that can be attracted by the electromagnet 3, for example, the magnet 4 is a permanent magnet, an iron block, etc.

[0066] Specifically, Figure 5 As shown, the display screen connecting portion 102 is provided with an electromagnet 3, such as Figure 6As shown, the back 201 of the display screen 2 is provided with a magnet 4, which is convenient for line arrangement and connection. When the electromagnet 3 is energized, magnetism is generated, which can attract the magnet 4, thereby strengthening the connection between the display screen 2 and the fixing frame assembly 1, and realizing the function of locking the display screen 2. When the electromagnet 3 loses power, the magnetism disappears and no longer attracts the magnet 4, thereby releasing the lock and realizing the function of releasing the display screen 2. It should be noted that the magnetic force of the electromagnet 3 is affected by factors such as the current size, the number of coil turns, the material and shape of the core, etc. In practical applications, appropriate parameters and configurations can be selected according to specific needs and conditions to achieve the desired magnetic effect.

[0067] Optionally, the number of electromagnets 3 is multiple, and correspondingly, the number of magnets 4 is multiple, and the multiple electromagnets 3 and the multiple magnets 4 correspond to each other one by one and are evenly distributed, which can further improve the locking reliability of the display screen 2. For example, in this embodiment, the number of electromagnets 3 and the number of magnets 4 are two respectively. It should be noted that the number of electromagnets 3 and magnets 4 can be specifically determined according to actual design requirements.

[0068] With such arrangement, the display screen 2 can be locked easily by the strong magnet, thus ensuring the stability and safety of the display screen 2 when needed, and the operation is convenient and reliable, so as to meet the different usage requirements of users.

[0069] Of course, in other embodiments, the locking structure 20 includes but is not limited to the locking method of the electromagnet 3, and also includes locking methods such as openable and closable clamping claws and retractable latches, and makes adaptive adjustments to achieve the function of locking or releasing the display screen 2. For example, the locking structure 20 adopts a clamping claw structure, and the clamping claw can be controlled to open or close by pneumatic, hydraulic or mechanical control. Taking the cylinder clamping claw as an example, the piston rod is driven to move by compressed air, and then the clamping claw is driven to close or open, thereby locking or releasing the display screen 2. Alternatively, the locking structure 20 adopts a latching pin structure, which can be connected to the latching pin through a motor and a lead screw nut transmission mechanism, and the back 201 of the display screen 2 is correspondingly provided with a pin hole adapted to the latching pin. In this way, the lead screw is driven to rotate by a motor, and then the latching pin is driven to insert or withdraw from the pin hole, thereby locking or releasing the display screen 2.

[0070] Specifically, Figure 5 As shown, in some embodiments of the present invention, the fixing frame assembly 1 includes a first fixing frame 103 and a second fixing frame 104. The first fixing frame 103 is provided with a display screen connection portion 102, and the second fixing frame 104 is connected to the first fixing frame 103, and the second fixing frame 104 is provided with a carrier connection portion 101.

[0071] Furthermore, one of the first fixing frame 103 and the second fixing frame 104 is provided with a spherical portion 5, and the other is provided with a spherical groove 6, and the spherical portion 5 is rotatably engaged in the spherical groove 6. In other words, the first fixing frame 103 is provided with a spherical portion 5, and the second fixing frame 104 is correspondingly provided with a spherical groove 6. Alternatively, the second fixing frame 104 is provided with a spherical portion 5, and the first fixing frame 103 is correspondingly provided with a spherical groove 6. For example, Figure 7 As shown, the first fixing frame 103 is provided with a spherical portion 5 , and the second fixing frame 104 is correspondingly provided with a matching spherical groove 6 , and the spherical portion 5 is rotatably engaged in the spherical groove 6 .

[0072] For this setting, see Figure 2 As shown, the spherical portion 5 and the spherical groove 6 cooperate with each other to form a spherical connection structure, and the first fixing frame 103 and the second fixing frame 104 are connected through the spherical connection structure, so that the first fixing frame 103 together with the display screen 2 can be rotated at any angle relative to the second fixing frame 104. For example, the display screen 2 can switch between the horizontal screen and the vertical screen state, which is convenient for users to perform entertainment operations, etc., and meets the user's use needs. In addition, the spherical connection structure can realize the angle adjustment of the display screen 2, avoiding the light of the display screen 2 from being reflected to the driver's eyes through the front windshield and the front door glass, meeting the use needs of drivers of different heights, solving the reflection problem of the display screen 2, and ensuring driving safety.

[0073] Further, in some embodiments of the present invention, one of the spherical portion 5 and the spherical groove 6 is provided with a limiting groove 7, and the other is provided with a limiting protrusion 8, and the limiting protrusion 8 is engaged in the limiting groove 7. That is, the spherical portion 5 is provided with a limiting groove 7, and the spherical groove 6 is correspondingly provided with a limiting protrusion 8. Alternatively, the spherical groove 6 is provided with a limiting groove 7, and the spherical portion 5 is correspondingly provided with a limiting protrusion 8. Specifically, as Figure 4 As shown, the spherical portion 5 is provided with a limiting groove 7 , and the spherical groove 6 is correspondingly provided with a matching limiting protrusion 8 , and the limiting protrusion 8 is snap-fitted into the limiting groove 7 .

[0074] Furthermore, at least one of the limiting groove 7 and the limiting protrusion 8 is plural in number. Figure 8 As shown, the number of the limiting protrusion 8 is one, the number of the limiting grooves 7 is multiple, and the multiple limiting grooves 7 are arranged in an array. Alternatively, the number of the limiting grooves 7 is one, the number of the limiting protrusions 8 is multiple, and the multiple limiting protrusions 8 are arranged in an array. Alternatively, the number of the limiting grooves 7 and the limiting protrusions 8 are both multiple, and they are arranged in an array respectively. In this way, through the corresponding engagement of different limiting protrusions 8 and limiting grooves 7, the position of the spherical portion 5 in the spherical groove 6 can be relatively stable after the spherical portion 5 is rotated into place.

[0075] In this way, when the display screen 2 is rotated to a desired angle, the limiting protrusion 8 is engaged in a suitable limiting groove 7 to prevent the display screen 2 from further rotating, thereby limiting the display screen 2 and ensuring that the position of the display screen 2 remains relatively stationary. Only under the action of external force can the display screen 2 be rotated again to adjust the angle.

[0076] like Figure 8 As shown, in an optional embodiment of the present invention, the second fixing frame 104 includes a first connecting member 1041 and a second connecting member 1042. The first connecting member 1041 is provided with a carrier connecting portion 101, and the second connecting member 1042 is arranged opposite to the first connecting member 1041 and is detachably connected. At the same time, the first connecting member 1041 and the second connecting member 1042 are respectively provided with a spherical concave portion 1043, as shown in FIG. Figure 7 As shown, a pair of spherical recessed portions 1043 enclose a spherical groove 6 .

[0077] Specifically, the second connecting member 1042 and the first connecting member 1041 are connected by bolts 19. Figure 8 As shown, the second connecting member 1042 and the first connecting member 1041 are respectively provided with opposite mounting holes 1044, and the bolts 19 are passed through the mounting holes 1044. Further, mounting holes 1044 are provided on both sides of the spherical recessed portion 1043, so that the first connecting member 1041 and the second connecting member 1042 are more tightly connected, thereby reliably clamping the spherical portion 5.

[0078] During installation, the spherical part 5 is placed into the spherical recessed part 1043 on the first connecting member 1041, and then the second connecting member 1042 is buckled and fastened by bolts 19, so that the spherical part 5 is closely fitted with the spherical recessed parts 1043 on both sides, and the spherical part 5 is clamped. In this way, disassembly and maintenance are convenient, and assembly efficiency and installation flexibility are improved. In addition, if Figure 2 As shown, an upper cover plate 14 and a lower cover plate 15 are respectively provided on both sides of the second fixing frame 104 to make the dashboard 16 neat and beautiful in appearance.

[0079] See also Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the quick-release structure 17 includes at least two pairs of permanent magnets 1701 with opposite magnetic properties, one pair of permanent magnets 1701 is respectively arranged on the display screen 2 and the display screen connecting portion 102, and multiple pairs of permanent magnets 1701 are arranged in an array. Specifically, multiple pairs of permanent magnets 1701 are in a rectangular array and are evenly arranged on the contact surface of the display screen 2 and the display screen connecting portion 102. For example, in this embodiment, the number of permanent magnets 1701 is six pairs, which are evenly distributed from top to bottom. Figure 5As shown, the first fixing frame 103 is provided with a display screen connecting portion 102. The first fixing frame 103 is rectangular, and permanent magnets 1701 are respectively provided at its four vertices, and a permanent magnet 1701 is also provided in the middle of the long side, that is, six permanent magnets 1701 are arranged in three rows and two columns. Figure 6 As shown, six permanent magnets 1701 are correspondingly disposed on the back 201 of the display screen 2, and the six permanent magnets 1701 are arranged in three rows and two columns.

[0080] With such an arrangement, a stable magnetic field can be generated by the permanent magnets 1701 arranged in pairs, and magnetic force can be continuously provided without the need for an external power supply to fix the display screen 2. The magnetic force of the permanent magnets 1701 can be used to achieve quick connection and disassembly between the display screen 2 and the display screen connecting part 102, which is easy to maintain, improves work efficiency and ease of use, simplifies the connection structure, and is suitable for occasions where the display screen 2 needs to be removed for multiple operations.

[0081] At the same time, multiple pairs of permanent magnets 1701 are arranged in an array, which can enhance the magnetic effect, ensure a tight connection between the display screen 2 and the display screen connecting part 102, and improve the overall stability and reliability of the device. This arrangement also helps to achieve a more uniform magnetic distribution and avoid connection failure due to excessive local stress.

[0082] Furthermore, if Figure 3 As shown, in some embodiments of the present invention, an elastic buffer pad 18 is provided on the surface of the permanent magnet 1701. It is understandable that the elastic buffer pad 18 can be selected with a suitable material and thickness according to actual design requirements to meet its use requirements. Specifically, the elastic buffer pad 18 can be made of rubber material, polyurethane material, polyester material, etc.

[0083] With such a configuration, when the display screen 2 is installed, the elastic buffer pad 18 can effectively absorb and disperse the impact force, play a role in buffering and reducing shock and noise, improve the comfort of use, and prevent the permanent magnet 1701 from direct collision or friction and wear during the connection or disassembly process, which can protect the permanent magnet 1701 from damage and extend the service life of the permanent magnet 1701. In addition, the softness of the elastic buffer pad 18 makes it easier to overcome the magnetic force during the disassembly process, so as to achieve rapid disassembly.

[0084] Optionally, in other embodiments of the present invention, the quick-release structure 17 can also use a permanent magnet and an iron block arranged in pairs, and the permanent magnet and the iron block are respectively arranged on the display screen 2 and the display screen connecting portion 102 to achieve quick connection and disassembly of the display screen 2 and the display screen connecting portion 102, without using traditional fasteners such as screws and nuts, which greatly improves work efficiency and convenience. The number of permanent magnets and iron blocks can be multiple pairs, and they are evenly arranged on the contact surface of the display screen 2 and the display screen connecting portion 102.

[0085] Alternatively, in some other embodiments of the present invention, the quick-release structure 17 may also adopt a suction cup structure, the suction cup is mounted on the display screen connection portion 102, and the suction cup can be adsorbed on the back 201 of the display screen 2, thereby realizing quick connection and removal of the display screen 2 through negative pressure adsorption. In this way, the user can easily achieve connection or removal by operating the suction cup, without using tools or additional fasteners, and the operation is simple and convenient.

[0086] As an optional embodiment of the present invention, Figure 5 and Figure 6 As shown, one of the display screen 2 and the display screen connecting portion 102 is provided with a positioning member 9, and the other is provided with a positioning hole 10, and the positioning member 9 is inserted into the positioning hole 10. In other words, the display screen 2 is provided with a positioning member 9, and the display screen connecting portion 102 is correspondingly provided with a positioning hole 10. Alternatively, the display screen connecting portion 102 is provided with a positioning member 9, and the display screen 2 is correspondingly provided with a positioning hole 10.

[0087] Specifically, Figure 5 As shown, the display screen connecting portion 102 is provided with a positioning hole 10. Figure 6 As shown, the back 201 of the display screen 2 is correspondingly provided with a matching positioning member 9, and the positioning member 9 is inserted into the positioning hole 10. Further, the number of the positioning holes 10 is at least two, and the plurality of positioning holes 10 are evenly arranged on the display screen connecting portion 102. The number of the positioning members 9 is two, and the plurality of positioning members 9 and the plurality of positioning holes 10 correspond one to one. For example, the number of the positioning members 9 and the number of the positioning holes 10 are both two. In addition, the positioning hole 10 can be designed as a waist-shaped hole to reduce manufacturing errors and positioning errors, etc.

[0088] Such arrangement, through the cooperation between the positioning member 9 and the positioning hole 10, provides precise guiding and positioning functions, ensuring that the display screen 2 and the display screen connecting portion 102 can be accurately aligned when connected, thereby ensuring that the display screen 2 and the display screen connecting portion 102 can be accurately and firmly connected together, improving the connection accuracy and stability, and being easy to operate, and easy to install quickly and accurately.

[0089] Furthermore, if Figure 7 As shown, an inclined guide portion 901 is provided at the end of the positioning member 9, which provides a guiding effect during the assembly process, so that the positioning member 9 can be inserted into the positioning hole 10 more easily and accurately, which helps to reduce friction and resistance during assembly and improve assembly efficiency and accuracy.

[0090] See also Figure 5 and Figure 6As shown, in some embodiments of the present invention, one of the display screen 2 and the display screen connection part 102 is provided with a display screen harness plug 11, and the other is provided with a display screen harness socket 12, and the display screen harness plug 11 is plugged with the display screen harness socket 12. That is, the display screen 2 is provided with a display screen harness plug 11, and the display screen connection part 102 is correspondingly provided with a display screen harness socket 12. Alternatively, the display screen connection part 102 is provided with a display screen harness plug 11, and the display screen 2 is correspondingly provided with a display screen harness socket 12.

[0091] Specifically, Figure 5 As shown, the display screen connection portion 102 is provided with a display screen harness socket 12, such as Figure 6 As shown, the display screen 2 is correspondingly provided with a matching display screen harness plug 11. The harness 13 is connected to the display screen harness socket 12, and the display screen harness plug 11 is plugged into the display screen harness socket 12. In this way, the line layout and connection are convenient, and the operation is convenient.

[0092] With such a design, a quick-connect plug structure is constructed by setting up a matching display wiring harness plug 11 and a display wiring harness socket 12 for electrical connection. The structure is suitable for application scenarios where the display screen 2 is frequently removed, and the pins and slots are in close contact, which can provide a reliable electrical connection and ensure that signals and data can be stably transmitted to the display screen 2.

[0093] Furthermore, the spherical portion 5 is designed as a hollow sphere, and the wiring harness 13 passes through the interior of the spherical portion 5 and is connected to the display wiring harness socket 12, thereby facilitating the rotation of the display screen 2 and adjusting the angular position of the display screen 2 while ensuring reliable communication.

[0094] Preferably, in some embodiments of the present invention, the display screen 2 is provided with a wireless communication module and a battery (not shown in the figure), and the wireless communication module and the battery are arranged inside the display screen 2, thereby maintaining a neat appearance of the display screen 2 and ensuring the integrity of its functions.

[0095] The wireless communication module is used to communicate with the vehicle, allowing the display screen 2 to communicate with the vehicle wirelessly, so that various information from the vehicle, such as vehicle status, navigation data, entertainment content, etc., can be received and displayed on the screen. Therefore, when the display screen 2 is removed, it is ensured that the display screen 2 can still work normally and maintain communication with the vehicle. It should be noted that the wireless communication module is a mature technology in the relevant technology, so its specific structure and the like are not described here. The wireless communication module can adopt technologies such as Bluetooth, Wi-Fi, and vehicle-specific communication protocols, depending on the compatibility and design requirements of the vehicle and the display screen 2.

[0096] The battery is used to power the display screen 2, so that when the display screen 2 is removed, it can be used as a power source for the display screen 2 to ensure that the display screen 2 can work normally without an external power supply connection, which is convenient for users to use. It is understandable that the capacity and endurance of the battery will vary according to the power consumption, frequency of use, and design requirements of the display screen 2. In addition, the battery can be a rechargeable battery, thereby providing it with a durable and renewable power supply solution, so that the display screen 2 can continue to work without an external power supply, without the need to frequently replace the battery, and providing users with more convenience and flexibility. At the same time, the use of rechargeable batteries is also in line with the design concept of environmental protection and energy saving.

[0097] According to an embodiment of the present invention, on the other hand, a method for fixing a display screen is provided, which is used to control the display screen device for a vehicle in each of the above embodiments. Specifically, Fig. 9 As shown, the fixing method of the display screen includes:

[0098] Get the driving status of the vehicle;

[0099] The locking structure 20 is controlled to lock the display screen 2 or release the display screen 2 according to the driving state of the vehicle.

[0100] In this way, the control module obtains the driving status of the vehicle in real time, and controls the locking structure 20 according to the driving status of the vehicle to achieve forced locking of the display screen 2, or release the display screen 2, thereby meeting the usage requirements in different scenarios such as high and low speed driving, urban roads, and outdoor camping, improving the user experience and improving driving safety.

[0101] Further, in some embodiments of the present invention, the locking structure 20 includes an electromagnet 3 and a magnet 4 that attract each other. One of the display screen 2 and the display screen connecting portion 102 is provided with an electromagnet 3, and the other is provided with a magnet 4. For example, the display screen connecting portion 102 is provided with an electromagnet 3, and the back 201 of the display screen 2 is correspondingly provided with a magnet 4.

[0102] In this embodiment, the driving state includes the vehicle speed, such as Fig.10 As shown, controlling the locking structure 20 to lock the display screen 2 or release the display screen 2 according to the driving state includes:

[0103] The electromagnet 3 is energized or de-energized according to the vehicle speed to lock the display screen 2 or release the display screen 2 .

[0104] Specifically, the vehicle speed can be monitored by a vehicle speed sensor, and the vehicle speed information can be sent to the control module. The control module is electrically connected to the electromagnet 3, and the control module controls the electromagnet 3 to be energized or de-energized according to the received vehicle speed information, so as to lock the display screen 2 or release the display screen 2.

[0105] In this way, during driving, such as when driving at high speed, the control module controls the electromagnet 3 to be energized and lock the display screen 2. At this time, the lock can be forcibly opened to prevent the display screen 2 from being removed, thereby ensuring driving safety. If driving at low speed, the control module controls the electromagnet 3 to lose power and release the display screen 2. At this time, the user can remove the display screen 2 for entertainment and leisure.

[0106] Preferably, in some embodiments of the present invention, Fig.11 As shown, the method for fixing the display screen also includes:

[0107] When the vehicle speed is greater than or equal to a first preset speed, the current flowing through the electromagnet 3 is controlled to be a first current, so that the electromagnet 3 generates a first magnetic force;

[0108] When the vehicle speed is less than or equal to the second preset speed, the current flowing through the electromagnet 3 is controlled to be the second current, so that the electromagnet 3 generates a second magnetic force.

[0109] Among them, the first preset speed is greater than the second preset speed, the first current is greater than the second current, and the first magnetic force is greater than the second magnetic force. It should be noted that the first preset speed, the second preset speed, the first current, the second current, the first magnetic force and the second magnetic force can be specifically determined according to actual design requirements and are not limited here.

[0110] Specifically, the control module can use the PWM (Pulse Width Modulation) control method to adjust the current of the electromagnet 3, that is, the current of the electromagnet 3 is controlled by changing the duty cycle of the pulse signal. In PWM control, the high level time and low level time of the pulse signal can be adjusted. By changing the proportion of the high level time to the entire cycle time, that is, the duty cycle, accurate control of the current of the electromagnet 3 can be achieved. When the duty cycle increases, the current of the electromagnet 3 increases, and vice versa.

[0111] In this way, when driving at high speed, the control module controls the electromagnet 3 to pass a larger current so that the electromagnet 3 generates a stronger magnetic force, thereby firmly locking the display screen 2, ensuring that the user cannot remove the display screen 2 even if he / she applies force, thereby improving the safety of the vehicle. When the vehicle speed is low, a smaller current is passed through the electromagnet 3 to reduce the magnetic force of the electromagnet 3, thereby cooperating with the quick-release structure 17 to assist in fixing the display screen 2, and the user can apply force to remove the display screen 2 when necessary, which is more flexible and convenient to use.

[0112] In addition, a sensor for detecting the fastening force of the quick-release structure 17 may be provided, for example, a pressure sensor may be provided on the mating surface of the display screen 2 and the first fixing frame 103. If the quick-release structure 17 is not tightly fitted after long-term use, especially if a mechanical quick-release structure such as a clamping claw, a latch, etc. is used, it is inevitable that the structure will become loose after long-term use. When it is found after installation that the fastening force measured by the pressure sensor is less than or equal to the preset value, the control module determines that the quick-release structure 17 has become loose after long-term use. At this time, a smaller second current may be supplied to the electromagnet 3 to utilize the magnetic force of the electromagnet 3 to achieve the purpose of reinforcing the display screen 2, thereby achieving the effect of auxiliary fixation.

[0113] In an optional embodiment of the present invention, the driving state includes the vehicle body inclination angle, such as Fig.12 As shown, controlling the locking structure 20 to lock the display screen 2 or release the display screen 2 according to the driving state includes:

[0114] The electromagnet 3 is controlled to be energized or de-energized according to the inclination angle of the vehicle body to lock the display screen 2 or release the display screen 2 .

[0115] Specifically, the vehicle body inclination angle can be detected by a gyroscope sensor, and the vehicle body inclination angle information can be sent to the control module. The control module controls the electromagnet 3 to be energized or de-energized according to the received vehicle body inclination angle information, so as to lock the display screen 2 or release the display screen 2. In this way, when the vehicle is on an uphill scene, the electromagnet 3 can be controlled to be energized according to the vehicle body inclination angle, and the display screen 2 can be locked to prevent the display screen 2 from being removed or accidentally falling.

[0116] As an optional embodiment of the present invention, the driving state includes the vehicle height, such as Fig.13 As shown, controlling the locking structure 20 to lock the display screen 2 or release the display screen 2 according to the driving state includes:

[0117] The electromagnet 3 is energized or de-energized according to the vehicle body height control so as to lock the display screen 2 or release the display screen 2 .

[0118] Specifically, the vehicle height can be detected by the vehicle height sensor, and the vehicle height information can be sent to the control module. The control module controls the electromagnet 3 to be energized or de-energized according to the received vehicle height information, so as to lock the display screen 2 or release the display screen 2. In this way, in a bumpy scene, the vehicle can control the electromagnet 3 to be energized according to the vehicle height, and lock the display screen 2 to prevent the display screen 2 from being removed or accidentally falling. It should be noted that the vehicle height sensor measures the distance between the vehicle chassis and the ground.

[0119] According to an embodiment of the present invention, on the other hand, a vehicle is provided, comprising the vehicle display screen device as described in the above embodiments. The derivation process of this beneficial effect is roughly similar to the derivation process of the beneficial effect of the above vehicle display screen device, so it will not be repeated here.

[0120] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
