DETAILED DESCRIPTION
[0040] In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the embodiments of the present application will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0041] In the description of the present application, unless otherwise explicitly specified and limited, the terms "connected", "fixed" should be understood broadly, for example, can be fixedly connected, can be detachably connected or integrated; can be mechanically connected, can be electrically connected; can be directly connected, can be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0042] In the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature, which can include direct contact between the first and second features, or indirect contact between the first and second features through another feature therebetween. Moreover, the first feature "on", "above" and "on top of" the second feature includes the first feature directly above and obliquely above the second feature, or only indicates that the first feature is higher in horizontal height than the second feature. The first feature "under", "below" and "underneath" the second feature includes the first feature directly below and obliquely below the second feature, or only indicates that the first feature is lower in horizontal height than the second feature.
[0043] Touch screen devices are widely used in various scenarios, such as in vehicle-mounted electronic devices to realize navigation operation, music playing, air conditioning adjustment, etc. In order to provide a better and richer interactive experience, many touch screen devices integrate vibration feedback function, so that the user can perceive the operation time effectively without relying on vision after touching the screen. The vibration feedback after touch improves the operation reliability in complex scenarios, for example, in a vehicle-mounted environment, when the driver touches the screen to perform navigation confirmation operation, the driver can directly feel the screen vibration to confirm the operation success, avoid distraction to watch the screen, and reduce safety hazards.
[0044] However, the touch screen device in the related art generally includes a screen assembly and a shell, and the rear side of the screen assembly is connected to the shell by pasting glue in a whole circle. When the user's finger contacts the screen, the control system controls the vibration driver to drive the screen assembly to reciprocate relative to the shell to provide vibration feedback. The deformation of the glue on the rear side of the screen assembly provides the vibration displacement. However, such touch screen device has the following problems: the vibration feedback is not obvious, and the interactive experience is not good; the collapse feeling in the direction perpendicular to the screen is not good (for example, lacking physical displacement feedback when pressing), and when the touch screen device is installed on an assembly table in an application environment (for example, installed on the center console of a car), the touch screen device needs to be embedded in the assembly table as a whole.
[0045] To solve the problems of the touch screen device in the related art, the present application provides a touch screen device and a touch screen device installation assembly.
[0046] The touch screen device provides multi-directional deformation freedom through the elastic arm of the elastic structure, so that the pressing feeling and the vibration feedback effect are improved, and the existing problems such as fuzzy vibration feedback perception and poor pressing feeling are solved. The elastic structure cooperates with the pressure sensor to ensure the installation strength of the display screen body, support the pressure level feedback, and improve the touch interaction accuracy and safety.
[0047] The touch screen device of the present application is applied to vehicle-mounted electronic equipment. Of course, the touch screen device of the present application can also be applied to smart teaching equipment, smart home control equipment, medical equipment operating equipment, public self-service terminals and the like. Exemplarily, the touch screen device of the present application is applied to the vehicle-mounted field, and the touch screen device is installed at a central control position, installed at a rear seat area as a rear seat entertainment terminal, installed at an instrument panel area and the like. Among them, the user can directly control the zoom and path planning of the navigation map, the fine adjustment of the air volume / temperature of the air conditioner, the track switching and volume control of the multimedia playing interface through touch operation, or activate the voice assistant or driving mode switching function through long press or specific sliding track.
[0048] It should be noted that, in order to facilitate understanding of the relative positions between various components, the image displayed on the front side of the touch screen device facing the user is taken as an example, the side close to the user is the front side of each component and the touch screen device, and the side away from the user is the rear side of each component and the touch screen device, the left-right direction of the user is the left-right direction of the touch screen device, and the up-down direction of the user is the up-down direction of the touch screen device. For convenience of understanding, in the drawings, the x direction indicates the left-right direction, the y direction indicates the up-down direction, and the z direction indicates the front-rear direction.
[0049] Please refer to the following Figures 1 to 11 The touch screen device and the touch screen device mounting assembly of the present application will be described. The touch screen device comprises a display screen body 10, a fixing assembly 20 and a vibration driver 30.
[0050] The display screen body 10 comprises a display panel for displaying a picture. The front side of the display screen body 10 is used for displaying a picture and for the user to perform touch operation, and the rear side of the display screen body 10 is provided with the fixing assembly 20. The fixing assembly 20 comprises a fixing support 21, a plurality of elastic structures 22 and a pressure sensor 23, and the display screen body 10 is connected with the fixing support 21 through the plurality of elastic structures 22.
[0051] As Figures 1 to 3 , Figure 6 It is illustrated that the vibration driver 30 is connected with the display screen body 10, and the vibration driver 30 can be arranged at the rear side of the display screen body 10 or other positions. The vibration driver 30 is used to drive the display screen body 10 to vibrate relative to the fixing support 21.
[0052] Please continue to refer to Figure 5 , Figure 6 , Figure 8 , Figure 9The elastic structure 22 comprises a first fixing portion 221, a second fixing portion 222, and at least two elastic arm portions 223 arranged at intervals. The first fixing portion 221 is connected with the display screen body 10, and the second fixing portion 222 is connected with the fixing support 21. The first end of the elastic arm portion 223 is connected with the first fixing portion 221, and the second end is connected with the second fixing portion 222. The elastic arm portion 223 extends from the first end to the second end in a direction away from the display screen body 10, that is, the elastic arm portion 223 extends a certain distance from front to back. The elastic arm portion 223 can be perpendicular to the display screen body 10 or inclined at a certain angle relative to the display screen body 10. The elastic arm portion 223 has a deformation amount in the pressing direction and a deformation amount in the direction parallel to the display screen body 10. In this way, when a user presses the front surface of the display screen body 10 for touch operation, the display screen body 10 is displaced backward to provide a pressing feeling and realize a collapse feeling in the pressing direction. When the vibration driver 30 works to apply a reciprocating driving force to the display screen body 10, the elastic arm portion 223 can be deformed in the direction parallel to the display screen body 10, so that the display screen body 10 can reciprocate in the direction substantially parallel to the display screen body 10 relative to the fixing support 21, and the user can further feel the vibration feedback.
[0053] In each elastic structure 22, at least one elastic arm portion 223 is provided with a pressure sensor 23 for detecting the deformation of the elastic arm portion 223, so as to determine the size of the touch operation pressing force applied by the user to the front surface of the display screen body 10 according to the deformation amount of the elastic arm portion 223.
[0054] The touch screen device of the present application realizes the vibration feedback in the following manner. When a user touches and presses the display screen body 10, the elastic arm portion 223 in the elastic structure 22 is deformed under force, and the pressure sensor 23 thereon also detects the deformation signal and sends the deformation signal to the control module. After receiving the signal of the pressure sensor 23, the control module controls the vibration driver 30 to work, so that the display screen body 10 reciprocates relative to the fixing support 21. Different intensities of vibration feeling can be provided according to the size of the detected pressing force. Since the fixing support 21 is fixed in the external environment, the elastic arm portion 223 of the elastic structure 22 can be deformed, so that the touch screen device can be installed in the external environment through the fixing support 21, while providing the pressing feeling and the vibration feedback perception after touch.
[0055] Reference Figure 11The touch screen device mounting assembly includes an assembly table 90 and a touch screen device. The touch screen device is mounted on the assembly table 90 through a fixing support 21. Taking the application of the touch screen device to a vehicle-mounted system as an example, the assembly table 90 can be located at a center console, a rear side of a driver's seat or a passenger's seat, a dashboard area or the like in a vehicle interior. The assembly table 90 has an assembly surface provided with an assembly groove. The fixing assembly 20 is embedded in the assembly groove. The fixing support 21 is connected with the assembly table 90 through fastening, clamping or buckling and the like to mount the touch screen device on the assembly table 90. In addition, the display screen body 10 is located at a front side of the assembly table 90 to realize the effect of a "floating screen".
[0056] The touch screen device and the touch screen device mounting assembly have the following advantages:
[0057] Firstly, the elastic arm portions 223 can generate a sufficient deformation amount in the pressing direction and a direction parallel to the display screen body 10, so that the vibration feedback is more obvious, and the user can more clearly know whether the current touch operation is successful and the like. In addition, the collapse feeling in the pressing direction can be realized to improve the instant pressing feeling when the user presses the display screen body 10.
[0058] Secondly, in the related technical solution, when the user touches the screen of the display screen body 10, the contact point capacitance value changes, and the control module controls the vibration driver 30 to work based on the capacitance value change. Compared with this solution, the pressure sensor 23 is additionally arranged on the elastic arm portion 223, so that the touch pressing force can be judged based on the deformation amount of the elastic arm portion 223. Different vibration feedback intensities can be provided according to different pressing forces, for example, weaker vibration feedback is provided when the user "lightly presses" the screen, and stronger vibration feedback is provided when the user "heavily presses" the screen. In addition, based on the processing of the signal detected by the pressure sensor 23, weaker vibration feedback can be provided when the user "shortly presses", and stronger vibration feedback can be provided when the user "longly presses".
[0059] Thirdly, two elastic arm portions 223 are arranged in each elastic structure 22, which is beneficial to improve the support strength of the display screen body 10.
[0060] Fourthly, the plurality of elastic structures 22 are arranged at intervals, and the pressure sensor 23 is arranged on each elastic structure 22. In this way, when the user presses any position, the deformation of the elastic arm portion 223 at the different positions can be detected based on the pressure sensors 23 at the different positions, so that the detection sensitivity of the pressing touch operation is improved.
[0061] Fifth, when the touch screen device is installed, the display screen body 10 can present a "floating" effect. The display screen body 10 is connected with the fixed support 21 and can vibrate relative to the fixed support 21. In this way, the fixed component 20 can be distributed only in a local area at the back of the display screen body 10. Referring to Figure 11 When the display screen body 10 is installed, only the fixed support 21 needs to be embedded in the assembly groove of the assembly table 90 to shield the fixed component 20, so that the display screen body 10 can protrude forward relative to the assembly table 90. From the appearance, the display screen body 10 is located outside the assembly table 90, presenting a floating effect and a more beautiful appearance.
[0062] In an embodiment, the pressure sensor 23 is used for the deformation of the elastic arm portion 223. The pressure sensor 23 can be, but is not limited to, a strain gauge sensor, a piezoelectric film sensor, a MEMS pressure sensor 23, a fiber grating sensor, and a flexible pressure sensor 23. The pressure sensor 23 can be connected to the surface of the elastic arm portion 223 by pasting, screw locking, or the like. The pressure sensor 23 can also be inserted into the insertion slot inside the elastic arm portion 223 by insertion. The pressure sensor 23 can also be directly embedded in the inside of the elastic arm portion 223 during the processing stage without being exposed.
[0063] Optionally, the pressure sensor 23 is attached to the surface of the elastic arm portion 223 by pasting.
[0064] Optionally, the thickness direction of the elastic arm portion 223 is the left-right direction of the touch screen device, and the pressure sensor 23 is correspondingly arranged on the left surface or the right surface of the elastic arm portion 223.
[0065] Optionally, the elastic structure 22 has two elastic arm portions 223, and the pressure sensor 23 is arranged on only one of the elastic arm portions 223 to save cost. Of course, the pressure sensor 23 can also be arranged on both of the elastic arm portions 223 to improve detection accuracy.
[0066] In an embodiment, the vibration driver 30 is a linear motor. The linear motor is used as a vibration source, and a mass block is driven by electromagnetic force to reciprocate along a fixed shaft to generate directional vibration. The linear motor has the advantages of low cost, low driving voltage, adaptation to a vehicle power supply system, good vibration feedback effect, and the like. Compared with a piezoelectric ceramic driven by high voltage as the vibration driver 30, the linear motor does not need high voltage driving and can be driven at a lower cost.
[0067] In an embodiment, the display screen body 10 comprises a screen assembly 11 and a shell 12, the screen assembly 11 is installed on the shell 12, the screen assembly 11 comprises a display panel and the like, the fixed assembly 20 and the vibration driver 30 are arranged on the side of the shell 12 away from the screen assembly 11. Compared with arranging the components related to vibration feedback in the inside of the display screen body 10, the embodiment externally arranges the structure related to vibration feedback on the back side of the display screen body 10, which is beneficial to the light and thin design of the display screen body 10, and the display screen body 10 does not need to be embedded into the mounting table 90 as a whole during installation.
[0068] In an embodiment, the elastic structure 22 comprises a first fixed part 221, two elastic arm parts 223 and two second fixed parts 222, the two elastic arm parts 223 are respectively connected to the opposite sides of the first fixed part 221, and each elastic arm part 223 is connected with the second fixed part 222 at the end away from the first fixed part 221.
[0069] As Figures 6 to 8 illustrated, the elastic structure 22 of the embodiment is connected with the display screen body 10 through the first fixed part 221 and is connected with the fixed support 21 through the two spaced second fixed parts 222, so that the connection points between the display screen body 10 and the elastic structure 22 are not too many, and the display screen body 10 can obtain better sensitivity of displacement and reciprocating motion under the action of the vibration source.
[0070] Optionally, the first fixed part 221 is connected with the elastic arm part 223 at an angle, and the second fixed part 222 is connected with the elastic arm part 223 at an angle. In this way, the ability of the elastic arm part 223 to deform in multiple directions is taken into account, and the connection between the first fixed part 221 and the display screen body 10 and the connection between the second fixed part 222 and the fixed support 21 are facilitated.
[0071] Optionally, for the elastic structure 22 comprising a first fixed part 221 and two elastic arm parts 223, the pressure sensor 23 is arranged only on one of the elastic arm parts 223 to save cost.
[0072] In other embodiments, the elastic structure 22 comprises two first fixed parts 221, two elastic arm parts 223 and one second fixed part 222.
[0073] In an embodiment, in order to make the overall structure of the touch screen device simpler and improve the assembly efficiency, with reference to Figure 5 , the fixed support 21 is correspondingly provided with an avoidance through hole 211, the avoidance through hole 211 is located on the side of the first fixed part 221 away from the display screen body 10, and the avoidance through hole 211 is used for only needing the fastener to pass through the avoidance through hole 211 to lock the first fixed part 221 to the display screen body 10.
[0074] Exemplarily, the pressure sensor 23 is mounted on each elastic structure 22 when assembling. After the plurality of elastic structures 22 are mounted to the fixing support 21 using the first fastener 241 to lock the second fixing portion 222 to the front side of the fixing support 21, the assembling of the fixing assembly 20 is completed. Then, the fixing support 21 with the elastic structures 22 is mounted to the display screen body 10, and the position of the fixing assembly 20 is adjusted. Then, the second fastener 242 is passed through the avoiding through hole 211 from back to front, so that the second fastener 242 can lock the first fixing portion 221 to the display screen body 10 from back to front. By mounting the first fixing portion 221 of the plurality of elastic structures 22 to the display screen body 10, the assembling of the fixing assembly 20 and the display screen body 10 is completed.
[0075] In the embodiment, the components in the fixing assembly 20 can be pre-assembled into an assembly. This not only improves the assembling efficiency between the fixing support 21, the elastic structure 22, the pressure sensor 23 and the display screen body 10, but also facilitates subsequent maintenance. The avoiding through hole 211 can be used to release the connection between the first fixing portion 221 and the display screen body 10, so that the fixing assembly 20 can be detached from the display screen body 10 for maintenance or replacement.
[0076] In an embodiment, referring to Figure 5 , Figure 6 , Figure 8 , Figure 9 The elastic arm portion 223 is in the form of a thin plate, the thickness direction of the elastic arm portion 223 is consistent with the left-right direction of the display screen body 10, and the elastic arm portion 223 is configured to be bent along the left-right direction of the display screen body 10 under the action of external pressure.
[0077] In one aspect, the elastic arm portion 223 is adjusted to be able to bend and deform in the left-right direction, and the elastic arm portion 223 is not easy to bend and deform in the up-down direction, so that the elastic structure 22 provides touch vibration feedback and pressing displacement tactile feeling, and ensures the required support and fixing strength of the display screen main body 10 in the gravity direction, and multiple elastic structures 22 cooperate to stably support the display screen assembly. In a second aspect, when the user presses the front of the display screen main body 10 and slides left and right to adjust the temperature, adjust the air volume, adjust the volume, unlock the map, etc., the elastic arm portion 223 of the elastic structure 22 bends and deforms in the left-right direction, and the pressure sensor 23 shell more accurately and sensitively senses the pressure change, and then judges the operation state of the user, thereby intelligently providing vibration feedback. In a third aspect, when the user presses the front of the display screen main body 10 and slides left and right, the vibration driver 30 works, and the configuration mode of the elastic arm portion 223 makes the display screen main body 10 reciprocate in the left-right direction to provide vibration feedback, and the transverse vibration feedback is consistent with the gesture direction, and the feedback is more obvious. In a fourth aspect, the configuration mode of the elastic structure 22 is suitable for the case that the display screen main body 10 is an LCD or an OLED.
[0078] The mover in the linear motor can reciprocate along its motion axis L1, which is parallel to the display screen main body 10, and adopts a planar vibration scheme to avoid the noise caused by the front-back vibration drive causing the back light film to collide with each other, so that ordinary LCD display screen main body 10 can also adopt this vibration feedback scheme, and of course OLED display screen main body 10 can also be suitable for this vibration feedback scheme. Alternatively, as shown in the figure, Figure 2 The motion axis L1 of the linear motor mover is configured to be consistent with the left-right direction of the touch screen device. In other embodiments, the motion axis L1 of the linear motor mover can also be configured to be consistent with the up-down direction of the touch screen device. It can be understood that when the elastic arm portion 223 is configured to be able to bend and deform in the left-right direction, the touch screen main body will reciprocate left and right relative to the fixed support 21 as long as the linear motor works.
[0079] In one embodiment, referring to Figure 2, in order to give consideration to stable support to the display screen body 10, pressure detection and vibration feedback effect, the fixing assembly 20 comprises at least two groups of elastic connecting assemblies. Wherein, the at least two groups of elastic connecting assemblies are distributed along the left-right direction of the display screen body 10, each group of elastic connecting assemblies comprises two elastic structures 22, and the two elastic structures 22 are arranged along the up-down direction of the display screen body 10. When pressing a certain area, the pressures sensed by several pressure sensors 23 are different, and the pressing area and / or pressing force can be determined by processing the information by the controller, and the vibration area or vibration intensity can be controlled in the interaction. The double elastic connecting assemblies ensure that the vibration feeling uniformly covers the whole screen by controlling the left and right reverse partition, and the elastic structure 22 layout of the embodiment can provide better pressure detection and vibration feedback effect, and can accurately sense the starting point and ending point of sliding.
[0080] Exemplarily, as Figure 2 Illustratively, the left area and the right area of the back side of the display screen body 10 are respectively provided with a group of elastic connecting assemblies, and each group of elastic connecting assemblies comprises two elastic structures 22. Figure 10 During the process of the user performing the horizontal sliding operation of "touching point A and sliding to point B", the pressure sensors 23 in the two elastic structures 22 of the left first group of elastic connecting assemblies can sensitively sense the touch operation of point A while the user touches the starting point A, and the elastic arm deformation in the left first group of elastic connecting assemblies ensures that good vibration feedback can be received at the touch point A while the vibration driver 30 is working. Similarly, the right second group of elastic connecting assemblies can sensitively sense the touch operation of point B and provide good vibration feedback while the user slides to the ending point B. In this way, the pressing feeling and vibration feedback feeling of the user during the sliding operation at the sliding starting point and ending point are obvious.
[0081] The layout mode of the plurality of elastic structures 22 in the embodiment can not only provide sensitive pressure sensing and good vibration feedback during the user's sliding operation, improve the touch sliding operation experience, but also provide good touch feedback experience for ordinary single-point clicking operation. In addition, the elastic structures 22 in each group of elastic connecting assemblies are vertically cooperated to jointly support the weight of the display screen body 10.
[0082] In an embodiment, referring to Figure 2 , Figure 3 The touch screen device comprises at least two vibration drivers 30, and the plurality of vibration drivers 30 can reliably drive the display screen body 10 with a certain weight to vibrate relative to the fixed support 21, thereby providing good vibration feedback effect. The two vibration drivers 30 are arranged along the left-right direction, and left-right partition control can be realized.
[0083] Wherein, at least one vibration driver 30 is arranged between the two elastic structures 22 of each elastic connection assembly, the vibration driver 30 is located between the upper and lower elastic structures 22, and the vibration energy can directly act on the elastic arm parts 223 of the upper and lower elastic structures 22, forming the shortest energy transmission path, thereby reducing the transmission loss of vibration energy. The layout of the elastic structure 22 and the vibration driver 30 can make the vibration feedback more direct and efficient, and improve the vibration feedback effect.
[0084] Optionally, the display screen body 10 includes a display panel and a shell 12 behind the display panel. The shell 12 can be made of metal, but is not limited thereto. The shell 12 can be formed by a die casting process or the like.
[0085] Optionally, please continue to refer to Figure 2 , Figure 3 Two sets of elastic connection assemblies are arranged in the left and right regions of the rear side of the display screen body 10, respectively. One vibration driver 30 is arranged between the upper and lower elastic structures 22 of each elastic connection assembly. The elastic arm parts 223 in each elastic structure 22 are arranged in the left-right direction. The vibration driver 30 is configured to drive the display screen body 10 to reciprocate in the left-right direction relative to the fixed support 21.
[0086] The embodiment realizes the touch pressure detection of the left and right regions of the display screen and the partition control of the vibration feedback by the layout of the left-right symmetrical elastic connection assemblies and the arrangement of one vibration driver 30 between the upper and lower elastic structures 22. The interactive function of the vibration feedback is more abundant, and more diverse needs can be met. For example, when the driver performs touch operations such as map navigation point clicking on the left side, the vibration feedback of the left region is stronger than that of the right region, or only the left region vibrates (only the left vibration driver 30 works). When the copilot adjusts the entertainment menu on the right side, the vibration feedback of the right region is stronger than that of the left region, or only the right region vibrates (only the right vibration driver 30 works). In the second aspect, when performing a horizontal sliding operation, such as when the user adjusts the air conditioner temperature by sliding left and right, the display screen body 10 vibrates in the left-right direction. The touch feedback logic and operation intention are consistent, and the interactive experience is good. In the third aspect, the elastic arm parts 223 deform in the left-right direction under the action of the power source to provide a vibration deformation amount. The upper and lower elastic structures 22 are arranged in a mutually constrained manner, which can synchronously offset the bump interference. Figure 1
[0087] Optionally, please refer to Figure 5 , Figure 6 , Figure 8 In the case that two sets of elastic connecting assemblies are arranged along the left-right direction and one pressure sensor 23 is arranged on each elastic structure 22, the pressure sensor 23 is arranged on the outer elastic arm part 223 of the elastic structure 22. In each elastic structure 22, the two elastic arm parts 223 are arranged along the left-right direction at intervals; in each elastic structure 22, the elastic arm part 223 close to the other elastic connecting assembly is the inner arm part 2231, and the elastic arm part 223 away from the other elastic connecting assembly is the outer arm part 2232, and the pressure sensor 23 is mounted on the outer arm part 2232. The pressure sensor 23 arranged on the outer arm part 2232 is less affected by mechanical coupling from the other assembly, and the pressure detection signal is more accurate, thereby improving the accuracy of left-right area pressure detection.
[0088] Optionally, the pressure sensor 23 is mounted on the side of the outer arm part 2232 away from the inner arm part 2231, so that the pressure sensor 23 can be attached to the outer arm part 2232 from the outside, and the pressure sensor 23 is convenient to install.
[0089] In an embodiment, the display screen body 10 includes a screen assembly 11 and a shell 12, the screen assembly 11 is mounted on the shell 12, the screen assembly 11 includes a display panel and the like, and the fixed assembly 20 and the vibration driver 30 are arranged on the side of the shell 12 away from the screen assembly 11. As shown in the figure, Figure 3 Figure 6 Optionally, the side of the shell 12 away from the screen assembly 11 is provided with a mounting protrusion 121, and a mounting groove 1211 is formed at the rear side of the mounting protrusion 121, and the vibration driver 30 is at least partially clamped into the mounting groove 1211, and the vibration driver 30 is connected with the shell 12. In this way, the mounting groove 1211 provides the vibration driver 30 with mounting positioning and limiting effects, thereby facilitating to improve the installation stability of the vibration driver 30.
[0090] Optionally, referring to Figure 3 Figure 6 Optionally, the vibration driver 30 is clamped into the mounting groove 1211, and the vibration driver 30 is connected with the shell 12 through a fastener, thereby achieving the mounting and fixing of the vibration driver 30.
[0091] Optionally, a filling material such as glue is filled between the vibration driver 30 and the groove wall of the mounting groove 1211, so as to fill the gap between the vibration driver 30 and the groove wall, thereby enabling the vibration energy of the vibration driver 30 to be more efficiently transmitted to the display screen body 10, and reducing energy loss.
[0092] In other embodiments, the vibration driver 30 can be directly pasted and fixed to the rear side of the shell 12 through strong glue or other pasting materials.
[0093] In an embodiment, the size of the fixing support 21 is smaller than the size of the display screen body 10, and the fixing support 21 is provided with a fixing mounting portion which can be locked to the vehicle body mounting table 90 by fasteners. In this way, after the installation of the touch screen device is completed, a region on the rear side of the display screen body 10 can appear to be suspended on the mounting table 90, and the appearance effect is good. Moreover, the display screen body 10 does not need to be completely embedded into the mounting table 90, and when a larger size display screen body 10 is used, it is not necessary to consider whether there is a large enough space in the mounting table 90 to embed the display screen body 10.
[0094] In an embodiment, the plurality of elastic structures 22 and the vibration driver 30 are arranged in a mounting region on the rear side of the display screen body 10, and the mounting region is located at the middle lower part of the display screen body 10. For example, the display screen body 10 has an upper side edge and a lower side edge in the up-down direction, the distance between the mounting region and the upper side edge is d1, and the distance between the mounting region and the lower side edge is d2, and d1≥1.5d2.

[0096] Optionally, the first circuit board 50 is electrically connected to the control module, so that the display screen body 10 can be synchronized with corresponding touch operations and / or display content while providing pressure detection and vibration feedback.
[0097] Optionally, the control module comprises a TFT (Thin Film Transistor Array).
