Technical Field

[0001] This utility model relates to the field of touch feedback technology, and in particular to a touch screen device and a touch screen device mounting assembly. Background Technology

[0002] Touchscreen devices, also known as touch displays or touch screen monitors, are interactive devices that integrate input and display functions. They detect the contact signals of a user's finger or stylus and drive the control system to respond to clicks, swipes, or presses. In the field of automotive electronics, touchscreen devices are widely used in central control systems, rear-seat entertainment terminals, etc., allowing users to perform interactive functions such as navigation, air conditioning control, and multimedia control by touching the main display screen. In related technologies, the screen vibrates to provide haptic feedback after the user touches the main display screen.

[0003] However, in the related technologies, the touch screen devices have problems such as poor pressing feel during touch operation and poor vibration feedback, resulting in a poor user experience. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a touch screen device and a touch screen device mounting assembly, thereby improving the touch vibration feedback experience.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A touch screen device, comprising:

[0007] Display screen body;

[0008] A fixing component is disposed on the rear side of the display screen body; the fixing component includes a fixing bracket, multiple single-arm springs, and multiple pressure sensors. There is a mating gap between the display screen body and the fixing bracket. The display screen body is connected to the fixing bracket via multiple single-arm springs disposed within the mating gap. Each single-arm spring includes a first fixing part connected to the display screen body, a second fixing part connected to the fixing bracket, and an elastic arm connecting the first fixing part and the second fixing part. The elastic arm extends from front to back, and the pressure sensor is disposed on the elastic arm for detecting the elastic deformation of the elastic arm.

[0009] A vibration driver is installed on the main body of the display screen.

[0010] Optionally, the first fixing part is angularly connected to the first end of the elastic arm, and the second fixing part is angularly connected to the second end of the elastic arm; in a direction parallel to the display screen body, the first fixing part and the second fixing part are located on opposite sides of the elastic arm.

[0011] Optionally, the elastic arm is a thin plate and is configured to bend along the left-right direction of the display body under external pressure.

[0012] Optionally, the fixing component includes at least two sets of elastic connecting components, which are spaced apart along the left-right direction of the display screen body; each set of elastic connecting components includes two single-arm springs, which are spaced apart along the up-down direction of the display screen body.

[0013] Optionally, it includes a first circuit board, which is disposed between the display screen body and the fixed bracket, and all pressure sensors are electrically connected to the first circuit board;

[0014] The first circuit board is disposed between the two sets of elastic connection components; the single-arm spring in the elastic connection component is configured such that the elastic arm can elastically deform along the left and right direction of the display body, and the pressure sensor is disposed on the side of the elastic arm close to the first circuit board.

[0015] Optionally, in one set of the elastic connection components, the two single-arm springs are respectively a first single-arm spring and a second single-arm spring, and in another set of the elastic connection components, the two single-arm springs are respectively a third single-arm spring and a fourth single-arm spring.

[0016] The first single-arm spring is closer to the upper side of the display screen body than the second single-arm spring, and the third single-arm spring is closer to the upper side of the display screen body than the fourth single-arm spring.

[0017] The plurality of single-arm springs also includes a fifth single-arm spring, which is located between the two sets of elastic connecting components along the left-right direction of the display body.

[0018] Optionally, the fixing component is disposed in the lower middle region of the rear side of the display screen body; the fifth single-arm spring is located near the upper side of the display screen body relative to the first single-arm spring and the third single-arm spring.

[0019] Optionally, the touch screen device includes at least two vibration drivers, with at least one vibration driver disposed between two single-arm springs in each set of elastic connection components.

[0022] The beneficial effects of this utility model are as follows: When the user presses the main body of the touch screen to perform a touch operation, the single-arm spring will deform under the force. After the pressure sensor on the elastic arm detects the deformation signal of the elastic arm, the vibration driver works, and the main body of the touch screen vibrates relative to the fixed support. When the main body of the touch screen vibrates, the elastic arm deforms.

[0023] When the user presses the touchscreen body and the touchscreen body vibrates, the elastic arm in the single-arm spring undergoes good deformation, which improves the pressing feel, the pressure detection effect is good, and the vibration energy transmission is efficient. The vibration feedback obtained by the user is clear, which helps to improve the user experience. Attached Figure Description

Detailed Implementation

[0038] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] Touchscreen devices, also known as touch displays or touch screen monitors, are interactive devices that integrate input and display functions. They detect the contact signals of a user's finger or stylus and drive the control system to respond to clicks, swipes, or presses. In the field of automotive electronics, touchscreen devices are widely used in central control systems, rear-seat entertainment terminals, etc., allowing users to perform interactive functions such as navigation, air conditioning control, and multimedia control by touching the main display screen. In related technologies, the screen vibrates to provide haptic feedback after the user touches the main display screen.

[0042] However, touchscreen devices in related technologies generally include a screen assembly and a housing. The entire rear edge of the screen assembly is flexibly connected to the housing via adhesive. When a user's finger touches the screen, the control system controls a vibration actuator to drive the screen assembly to reciprocate relative to the housing, providing vibration feedback. The deformation of the adhesive on the rear edge of the screen assembly provides the vibration displacement. However, this type of touchscreen device has the following problems: the vibration feedback is not obvious, resulting in a poor interactive experience; the tactile feedback perpendicular to the screen direction is poor (e.g., lack of physical displacement feedback when pressing); and when installing the touchscreen device on an assembly platform in the application environment (e.g., on the center console of a car), the entire touchscreen device needs to be embedded into the assembly platform.

[0043] In order to address the problems existing in touch screen devices in related technologies, this application provides a touch screen device and a touch screen device mounting component.

[0044] This touchscreen device provides multi-directional deformation freedom through the elastic arm in a single-arm spring, improving both the tactile feedback and vibration feedback, thus addressing issues such as vague vibration feedback and poor tactile feedback in related technologies. A pressure sensor is installed in the elastic arm; when the user touches or presses the display screen, the elastic arm deforms, sensing both the touch operation and the pressure level. This improves the timeliness of vibration feedback and allows for control of vibration intensity based on pressure, resulting in a better interactive experience.

[0045] The touchscreen device of this application is applied to in-vehicle electronic devices. Of course, the touchscreen device of this application can also be applied to intelligent teaching equipment, smart home control equipment, medical equipment operating equipment, public self-service terminals, etc. For example, the touchscreen device of this application is applied in the automotive field, and is installed in the center console, in the rear seat area as a rear seat entertainment terminal, or in the dashboard area, etc. Users can directly control the zooming and route planning of navigation maps, fine-tuning of air conditioning fan speed / temperature, track switching and volume control of multimedia playback interfaces through touch operation, or activate voice assistant or driving mode switching functions by long-pressing or using a specific swipe trajectory.

[0046] It should be noted that, to facilitate understanding of the relative positions of the components, taking an image displayed directly in front of the touchscreen device when the user is facing it as an example, the side closer to the user represents the front of all components and the touchscreen device, while the side away from the user represents the rear of all components and the touchscreen device. The user's left-right direction corresponds to the touchscreen device's left-right direction, and the user's up-down direction corresponds to the touchscreen device's up-down direction. For ease of understanding, in the accompanying drawings, the x-direction indicates left-right, the y-direction indicates up-down, and the z-direction indicates front-back.

[0047] Please refer to the following. Figures 1 to 11 This application describes the touch screen device and its mounting components. The touch screen device includes a display screen body 10, a fixing component 20, and a vibration driver 30.

[0048] The display screen body 10 is used to display images, display an interactive interface, and receive touch operations. A vibration driver 30 is connected to the display screen body 10 and can be located on the rear side of the display screen body 10 or at other positions. The vibration driver 30 is used to drive the display screen body 10 to vibrate relative to the fixed support 21.

[0049] The fixing component 20 is located on the rear side of the display body 10. The fixing component 20 includes a fixing bracket 21, multiple single-arm springs 22 and multiple pressure sensors 23. The fixing bracket 21 is located on the rear side of the display body 10 and has a mating gap with the display body 10. The multiple single-arm springs 22 are installed in the mating gap. The display body 10 is connected to the fixing bracket 21 through the multiple single-arm springs 22. The single-arm springs 22 can deform under touch pressure or vibration source, thereby providing a pressing feel or allowing the display body 10 to reciprocate relative to the fixing bracket 21 to provide vibration feedback.

[0050] Please continue to refer to Figure 5 , Figure 7 , Figure 9 , Figure 12The single-arm spring 22 includes a first fixing part 221, an elastic arm 223, and a second fixing part 222, with one elastic arm 223. The first fixing part 221 is connected to the display screen body 10, and the second fixing part 222 is connected to the fixing bracket 21. The first end of the elastic arm 223 is connected to the first fixing part 221, and the second end is connected to the second fixing part 222, so that the elastic arm 223 extends from its first end to its second end in a direction away from the display screen body 10, that is, the elastic arm 223 extends a certain distance from front to back. The elastic arm 223 can be perpendicular to the display screen body 10 or tilted at a certain angle relative to the display screen body 10. The elastic arm 223 has a deformation in the pressing direction and a deformation parallel to the display body 10. Thus, not only does the display body 10 shift backward to provide a pressing feel when the user presses the front of the display body 10 for touch operation, achieving a collapsing feel in the pressing direction, but also, when the vibration driver 30 operates to apply a reciprocating driving force to the display body 10, the elastic arm 223 can deform in a direction parallel to the display body 10, allowing the display body 10 to reciprocate in a direction approximately parallel to the fixed support 21, so that the user can feel the vibration feedback.

[0051] Pressure sensor 23 is disposed on the elastic arm 223 of the single-arm spring 22. Pressure sensor 23 is used to detect the deformation of elastic arm 223, thereby determining the magnitude of the touch operation pressure applied by the user to the front of the display body 10 based on the amount of deformation of elastic arm 223.

[0052] The touchscreen device of this application implements vibration feedback as follows: When a user touches or presses the display screen body 10, the elastic arm 223 of the single-arm spring 22 deforms under force. The pressure sensor 23 on it detects the deformation signal and sends it to the control module. After receiving the signal from the pressure sensor 23, the control module controls the vibration driver 30 to work, causing the display screen body 10 to vibrate back and forth relative to the fixed bracket 21. Different intensities of vibration can be provided according to the detected pressing force. Since the fixed bracket 21 is fixed in the external environment, the elastic arm 223 of the single-arm spring 22 can deform, allowing the touchscreen device to be installed in the external environment through the fixed bracket 21, while providing a pressing feel and vibration feedback after touch.

[0053] Reference Figure 11The touchscreen device mounting assembly includes a mounting platform 90 and a touchscreen device. The touchscreen device is mounted on the mounting platform 90 via a fixing bracket 21. Taking the application of the touchscreen device in an in-vehicle system as an example, the mounting platform 90 can be located in the center console, behind the driver and passenger seats, or in the instrument panel area inside the car. The mounting platform 90 has a mounting surface with mounting slots. The fixing component 20 is embedded in the mounting slots. The fixing bracket 21 is connected to the mounting platform 90 by fasteners, snap-fit, or other means to mount the touchscreen device on the mounting platform 90. Furthermore, the display screen body 10 is located at the front of the mounting platform 90 to achieve a "floating screen" effect.

[0054] The advantages of the touch screen device and touch screen device mounting assembly of this application are:

[0055] First, it helps to improve the touch operation experience. The elastic arm 223 can generate a sufficient amount of deformation in both the pressing direction and the direction parallel to the display body 10, which can make the vibration feedback more obvious and allow users to know more clearly whether the current touch operation is successful. In addition, it can also realize the collapsing feel in the pressing direction, improving the instant pressing feel when the user presses the display body 10.

[0056] Secondly, in the relevant technical solutions, when a user touches the screen of the display body 10, the capacitance value at the contact point changes, and the control module controls the vibration driver 30 to work based on the capacitance value change. Compared with this solution, this application also adds a pressure sensor 23 to the elastic arm 223, thereby enabling the determination of the magnitude of the touch pressure by the deformation of the elastic arm 223. Different vibration feedback intensities can be provided according to different pressure magnitudes; for example, a weaker vibration feedback is provided when the user "lightly presses" the screen, and a stronger vibration feedback is provided when the user "presses" the screen. In addition, based on the processing of the signal detected by the pressure sensor 23, a weaker vibration feedback can be provided when the user "shortly presses" and a stronger vibration feedback can be provided when the user "long presses".

[0057] Third, each single-arm spring piece 22 has only one elastic arm 223, which improves pressure detection accuracy, vibration energy transmission efficiency, reduces vibration feedback delay, minimizes vibration feedback loss, and enhances the interactive experience. For example, if the vibration direction is left-right, and each single-arm spring piece 22 has only one elastic arm 223, it only needs to detect the deformation of the elastic arm 223 in a single direction (left or right bend). The signal detection is clear, reducing interference from other elastic arms 223. When the user lightly presses position A and continues to press A harder, the elastic arm 223 changes from a 10% tension on the right side to a 50% tension on the right side. During this process, the detection signal of the pressure sensor 23 changes regularly, resulting in high detection accuracy. When the vibration driver 30 drives the display screen body 10 to vibrate left and right, the elastic arm 223 at each single-arm spring piece 22 deforms synchronously left and right, resulting in a stable deformation path and high energy transmission efficiency.

[0058] Fourth, multiple single-arm springs 22 are spaced apart between the display screen body 10 and the fixed bracket 21. Each single-arm spring 22 is equipped with a pressure sensor 23. When the user presses any position, the deformation of the elastic arm 223 at different positions can be detected based on the pressure sensor 23 at different positions, resulting in good detection sensitivity.

[0059] Fifth, during installation, the touchscreen device allows the display body 10 to exhibit a "floating" effect. The display body 10 is connected to the fixed bracket 21 and can vibrate relative to the fixed bracket 21. This allows the fixing components 20 to be distributed only in a localized area on the rear side of the display body 10. When installing the display body 10, refer to... Figure 11 Simply embed the fixing bracket 21 into the assembly slot of the assembly table 90 to cover the fixing component 20, allowing the display body 10 to protrude forward relative to the assembly table 90. From the appearance, the display body 10 is located outside the assembly table 90 on all sides, presenting a floating effect, and the appearance is more beautiful.

[0060] In one embodiment, the pressure sensor 23 is used to control the deformation of the elastic arm 223. The pressure sensor 23 can be, but is not limited to, a strain gauge sensor, a piezoelectric film sensor, a MEMS pressure sensor, a fiber optic grating sensor, or a flexible pressure sensor. The pressure sensor 23 can be attached to the surface of the elastic arm 223 by means of adhesive bonding, screw tightening, etc., or it can be inserted into a slot inside the elastic arm 223 by insertion, or it can be directly embedded into the interior of the elastic arm 223 during the manufacturing stage without being exposed.

[0061] Optionally, the pressure sensor 23 is attached to the surface of the elastic arm 223 by means of adhesive.

[0062] Optionally, if the thickness direction of the elastic arm 223 is the left-right direction of the touch screen device, then the pressure sensor 23 is correspondingly disposed on the left or right surface of the elastic arm 223.

[0063] Optionally, the single-arm spring 22 has two elastic arms 223, with a pressure sensor 23 installed on only one elastic arm 223 to save costs. Of course, pressure sensors 23 can also be installed on both elastic arms 223 to improve detection accuracy.

[0064] In one embodiment, the vibration actuator 30 is a linear motor. Using a linear motor as the vibration source, a mass block is driven by electromagnetic force to reciprocate along a fixed axis, generating directional vibration. This method offers advantages such as low cost, low driving voltage, compatibility with vehicle power systems, and good vibration feedback. Compared to using high-voltage driven piezoelectric ceramics as the vibration actuator 30, using a linear motor eliminates the need for high-voltage drive, allowing for lower-cost implementation.

[0065] In one embodiment, the display body 10 includes a screen assembly 11 and a housing 12. The screen assembly 11 is mounted on the housing 12 and includes a display panel, etc. The fixing component 20 and the vibration driver 30 are disposed on the side of the housing 12 opposite to the screen assembly 11. Compared to placing the vibration feedback components inside the display body 10, this embodiment places the vibration feedback-related structures externally on the rear side of the display body 10, which is beneficial for the thinner and lighter design of the display body 10. During installation, the display body 10 does not need to be completely embedded in the mounting table 90.

[0066] In one embodiment, the first fixing part 221 is angularly connected to the first end of the elastic arm part 223, and the second fixing part 222 is angularly connected to the second end of the elastic arm part 223. The included angle between the two fixing parts and the elastic arm part 223 can be between 20 degrees and 160 degrees; optionally, the included angle between the fixing parts and the elastic arm part 223 is between 50 degrees and 130 degrees.

[0067] Optionally, the single-arm spring 22 is Z-shaped, which provides good vibration mode simulation, pressure detection, and feedback. In a direction parallel to the display body 10, the first fixing part 221 and the second fixing part 222 are located on opposite sides of the elastic arm 223. For example, the first fixing part 221 is on the left front end of the elastic arm 223, and the second fixing part 222 is on the right rear end of the elastic arm 223. The left-right misalignment of the first fixing part 221 and the second fixing part 222 allows the elastic arm 223 to easily deform left and right under a vibration source, resulting in low vibration energy loss. Furthermore, it facilitates the use of screws or other fasteners to lock the first fixing part 221 and the second fixing part 222 to the display body 10 and the fixing bracket 21 from both sides. It should be noted that when the single-arm spring 22 is described as Z-shaped, it only indicates that the two fixing parts are misaligned on both sides of the elastic part; it does not limit the size of the engagement angle between the two fixing parts and the elastic arm 223.

[0068] Or, such as Figure 12 As illustrated, the single-arm spring 22 is similar to a side U-shape. In a direction parallel to the display screen body 10, the first fixing part 221 and the second fixing part 222 are located on the same side of the elastic arm 223. For example, the first fixing part 221 is on the left side of the front end of the elastic arm 223, and the second fixing part 222 is on the left side of the rear end of the elastic arm 223.

[0069] In some embodiments, the multiple single-arm springs 22 located between the display body 10 and the fixed bracket 21 are all Z-shaped springs. Through the reasonable arrangement of the multiple single-arm springs 22, the load-bearing capacity is guaranteed while ensuring sensitive detection and rapid vibration feedback. In other embodiments, the multiple single-arm springs 22 located between the display body 10 and the fixed bracket 21 may be partially Z-shaped springs and partially U-shaped springs.

[0070] In one embodiment, reference is made to Figures 6 to 9 The elastic arm 223 is a thin plate, and the thickness direction of the elastic arm 223 is consistent with the left and right direction of the display body 10. The elastic arm 223 is configured to bend along the left and right direction of the display body 10 under external pressure.

[0071] On the one hand, the elastic arm 223 is adjusted to be able to bend and deform in the left and right directions, so the elastic arm 223 is not easy to bend and deform in the up and down direction. In this way, the single-arm spring 22 provides touch vibration feedback and pressing displacement feel while ensuring the support and fixing strength required by the display body 10 in the direction of gravity. Multiple single-arm springs 22 work together to stably support the display assembly. On the other hand, when the user presses the front of the display body 10 and slides left and right to perform operations such as temperature adjustment, air volume adjustment, volume adjustment, map unlocking, etc., the elastic arm 223 of the single-arm spring 22 bends and deforms in the left and right directions. The pressure sensor 23 shell senses the pressure change more accurately and sensitively, thereby judging the user's operation status and providing intelligent vibration feedback. On the other hand, when the user presses the front of the display body 10 and slides left and right, the vibration driver 30 works. The configuration of the elastic arm 223 makes the display body 10 vibrate back and forth in the left and right directions to provide vibration feedback. The lateral vibration feedback is consistent with the direction of the gesture, and the feedback is more obvious. Fourthly, this single-arm spring 22 setting method is applicable to both LCD and OLED display screen bodies 10.

[0072] The mover in the linear motor can reciprocate along its motion axis L1, which is parallel to the display screen body 10. A planar vibration scheme is used to avoid noise from the backlight films colliding with each other caused by back-and-forth vibration. This allows ordinary LCD display screen bodies 10 to also use this vibration feedback scheme, and of course, OLED display screen bodies 10 are also suitable for this vibration feedback scheme. Optionally, such as... Figure 4 As illustrated, the motion axis L1 of the linear motor actuator is configured such that its extension direction is consistent with the left-right direction of the touchscreen device. In other embodiments, not shown in the figure, the motion axis L1 of the linear motor can also be configured such that its extension direction is consistent with the up-down direction of the touchscreen device. It is understood that when the elastic arm 223 is configured to bend and deform in the left-right direction, the touchscreen body will reciprocate relative to the fixed support 21 whenever the linear motor is working.

[0073] In one embodiment, reference is made to Figures 1 to 4 To ensure stable support, pressure detection, and vibration feedback for the display body 10, the fixing component 20 includes at least two sets of elastic connecting components. These at least two sets of elastic connecting components are spaced apart along the left-right direction of the display body 10. Each set of elastic connecting components includes two single-arm spring pieces 22, which are spaced apart along the up-down direction of the display body 10.

[0074] When a certain area is pressed, the pressure sensed by the several pressure sensors 23 varies. The controller processes this information to determine the pressed area and / or the magnitude of the pressure. In terms of interaction, the vibration area or intensity can be controlled. The dual elastic connection assembly ensures uniform vibration coverage across the entire screen by controlling the left and right reverse partitions. Touch operations on both the left and right sides can be recognized based on the pressure sensors 23 on both sides. For some left and right swipe operations, the single-arm spring plate 22 layout in this embodiment provides better pressure detection and vibration feedback, accurately sensing the start and end points of the swipe.

[0075] For example, such as Figure 4 As shown, a set of elastic connecting components is respectively provided on the left and right sides of the rear side of the display body 10. Each set of elastic connecting components includes two single-arm spring pieces 22, one above the other. Figure 10 During the user's horizontal swipe operation of "touching point A and sliding towards point B," the pressure sensors 23 in the two single-arm springs 22 of the first set of elastic connecting components on the left can sensitively respond to the touch operation at point A. Simultaneously, while the vibration driver 30 is operating, the deformation of the elastic arms in the first set of elastic connecting components on the left ensures good vibration feedback at point A. Similarly, as the user slides to the end point B, the second set of elastic connecting components on the right can sensitively respond to the touch operation at point B and provide good vibration feedback. Thus, the user experiences noticeable pressure and vibration feedback at both the starting and ending points during the swipe operation.

[0076] In addition, the single-arm springs 22 arranged vertically in each set of elastic connection components work together in the vertical direction to jointly support the weight of the display body 10.

[0077] In one embodiment, a first circuit board 40 is included, which is disposed between the display screen body 10 and the fixed bracket 21. Multiple pressure sensors 23 are electrically connected to the first circuit board 40. The first circuit board 40 is used to receive and process the signals sent by the pressure sensors 23. The first circuit board 40 may also be referred to as a vibration feedback circuit board.

[0078] Optionally, the vibration driver 30 is also electrically connected to the first circuit board 40.

[0079] Optionally, the display body 10 has a control module inside, and the first circuit board 40 is electrically connected to the control module, so that while providing pressure detection and vibration feedback, the display body 10 can synchronously respond to touch operations and / or display content.

[0080] Optionally, the control module includes a TFT (thin-film transistor array), and the first circuit board 40 is electrically connected to the TFT. For example, when the user clicks the map zoom-in button, the first circuit board 40 receives the pressure signal, drives the vibration motor to vibrate briefly, and synchronously zooms in on the map display via the TFT.

[0081] Optionally, the first circuit board 40 is locked to the touch screen device or to the fixed bracket 21 by fasteners.

[0082] Alternatively, please continue to refer to Figure 4 , Figure 6 The first circuit board 40 is positioned between two sets of elastic connection components, which shortens the physical distance between each pressure sensor 23 and the first circuit board 40, making it easier for the pressure sensor 23 to be wired to the first circuit board 40.

[0083] Optionally, the single-arm spring 22 in the elastic connection assembly is configured such that the elastic arm 223 can elastically deform along the left-right direction of the display screen body 10, and the pressure sensor 23 is disposed on the side of the elastic arm 223 near the first circuit board 40. In this way, each pressure sensor 23 is disposed on the side of the elastic arm 223 near the first circuit board 40, thereby facilitating the wiring of the pressure sensor 23 to the first circuit board 40.

[0084] In one embodiment, such as Figure 4 The diagram illustrates that at least two sets of elastic connecting components are provided on the rear side of the display body 10, spaced apart in the left-right direction. In one set of elastic connecting components, two single-arm springs 22 are designated as a first single-arm spring 2201 and a second single-arm spring 2202, respectively. In the other set of elastic connecting components, two single-arm springs 22 are designated as a third single-arm spring 2203 and a fourth single-arm spring 2204, respectively. The first single-arm spring 2201 is closer to the upper side of the display body 10 than the second single-arm spring 2202, and the third single-arm spring 2203 is closer to the upper side of the display body 10 than the fourth single-arm spring 2204. The set of single-arm springs 22 also includes a fifth single-arm spring 2205, which is located between the two sets of elastic connecting components in the left-right direction of the display body 10. The fifth single-arm spring 2205 is located in the middle of the two sets of elastic connecting components on the left and right, which supplements the pressure detection capability of the middle area, balances the vibration energy on the left and right, and can add a support point in the middle to share the weight of the display screen body 10. The layout of these five single-arm springs 22 takes into account both the interactive experience and the support capability.

[0085] Optionally, the fixing component 20 is located in the lower-middle area of ​​the rear side of the display body 10, and the fifth single-arm spring 2205 is closer to the upper side of the display body 10 than the first single-arm spring 2201 and the third single-arm spring 2203. The fixing component 20 is positioned slightly lower overall, which can achieve a more aesthetically pleasing floating effect after the entire touch feedback device is installed, making the display body 10 resemble a floating screen. For example, the fixing bracket 21 is installed in the lower-middle position of the assembly platform 90 between the driver and passenger seats. Since the area of ​​the fixing bracket 21 is smaller than that of the display body 10 and it is located in the lower-middle part, there is no assembly platform 90 or vibration feedback-related structure obstructing the upper half of the display body 10. When viewed from the front, the display body 10 resembles a floating effect. Meanwhile, the fifth single-arm spring 2205, located between the two sets of elastic connecting components, has a touch detection blind spot compensation function. When the user clicks the top menu bar of the screen or slides the central area (such as zooming in and out of the in-vehicle navigation map), the pressure sensor 23 on the fifth single-arm spring 2205 can capture the touch pressure and supplement the detection capability of the four single-arm springs 22 arranged in the lower middle part of the left and right groups, avoiding signal attenuation or missed detection due to excessive distance, and ensuring that both light and heavy press operations can be accurately recognized.

[0086] Optionally, multiple single-arm springs 22 and vibration actuators 30 are all disposed in the mounting area on the rear side of the display screen body 10, and the mounting area is located in the lower middle part of the display screen body 10. For example, the display screen body 10 has an upper side and a lower side on both sides in the vertical direction, respectively. The distance between the mounting area and the upper side is d1, and the distance between the mounting area and the lower side is d2, where d1 ≥ 1.5d2.

[0087] In one embodiment, reference is made to Figures 1 to 4 , Figure 6 The touchscreen device includes at least two vibration actuators 30. These multiple vibration actuators 30 reliably drive the display screen body 10, which has a certain weight, to vibrate relative to the fixed support 21, providing good vibration feedback. The two vibration actuators 30 are spaced apart in the left-right direction, enabling left-right zone control. Multi-point fixed vibration ensures uniform vibration distribution, resulting in consistent vibration feedback across all screen positions and minimal impact from overall vehicle vibration.

[0088] In each set of elastic connection components, at least one vibration driver 30 is provided between the two single-arm springs 22. The vibration driver 30 is located between the upper and lower single-arm springs 22, and the vibration energy can directly act on the elastic arm 223 of the upper and lower single-arm springs 22, forming the shortest energy transmission path, thereby reducing the loss and attenuation of vibration energy transmission. This arrangement of single-arm springs 22 and vibration driver 30 can make vibration feedback more direct and efficient, and improve the vibration feedback effect.

[0089] Optionally, the main body of the display screen 10 includes a display panel and a housing 12 on the back side of the display panel. The housing 12 can be, but is not limited to, a metal material and can be formed by die casting or other methods.

[0090] Alternatively, please continue to refer to Figures 2 to 4 Two sets of elastic connecting components are respectively set in the left and right regions of the rear side of the display body 10. A vibration driver 30 is set between the upper and lower single-arm springs 22 of each set of elastic connecting components. The elastic arms 223 in each single-arm spring 22 are spaced apart in the left and right direction. The vibration driver 30 is configured to drive the display body 10 to reciprocate in the left and right direction relative to the fixed bracket 21.

[0091] This embodiment utilizes a symmetrical layout of elastic connecting components and a vibration actuator 30 positioned between each of the two single-arm spring pieces 22 to achieve zoned control of touch pressure detection and vibration feedback in the left and right areas of the display screen. This enriches the interactive functions of vibration feedback and meets more diverse needs. For example, when the driver performs touch operations such as clicking map navigation points on the left side, the vibration feedback in the left area is stronger than that in the right side, or only the left area vibrates (only the left vibration actuator 30 works). When the passenger adjusts the entertainment menu on the right side, the vibration feedback in the right area is stronger than that in the left side, or only the right area vibrates (only the right vibration actuator 30 works). Secondly, this layout also allows for horizontal sliding operations, such as when the user slides left or right to adjust the air conditioning temperature, causing the display screen body 10 to vibrate in the left-right direction. The tactile feedback logic is consistent with the operation intention. Figure 1 It has high consistency and a good interactive experience. Thirdly, the elastic arm 223 deforms in the left and right direction under the action of the power source to provide vibration deformation. It is set up with the upper and lower single-arm springs 22 to mutually constrain each other, which can synchronously cancel the disturbance of bumps.

[0092] In one embodiment, the display body 10 includes a screen assembly 11 and a housing 12. The screen assembly 11 is mounted on the housing 12 and includes a display panel, etc. The fixing component 20 and the vibration driver 30 are disposed on the side of the housing 12 away from the screen assembly 11.
