Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to an input device. Background Art

[0002] Vehicles are often equipped with input devices to facilitate user operation of in-vehicle electronic devices. In some vehicles, the input devices are touch-sensitive, replacing physical buttons, thereby enhancing the sense of technology in the vehicle cabin.

[0003] Some input devices of the prior art may include a base, a piezoelectric component mounted on the base, and a pressing plate. The pressing plate is arranged opposite to the piezoelectric component and covers the piezoelectric component. When the pressing plate is pressed toward the piezoelectric component, the pressing plate presses the piezoelectric component, causing the piezoelectric component to be triggered and generate the required signal. After the pressing force on the pressing plate is removed, the shape of the pressing plate is restored and separated from the piezoelectric component. Generally, the rigidity of the pressing plate is large, so when using the input device, a large force is required to press the pressing plate to trigger the piezoelectric component. This makes the input device inconvenient to use. Summary of the Invention

[0050] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0051] Figure 1A vehicle 1 according to an embodiment of the present application is schematically shown. The vehicle 1 is provided with an onboard electronic device (not shown) and an input device for controlling the onboard electronic device. For example, the input device may be provided on a steering wheel 11, a main instrument panel 12, a secondary instrument panel 13, a door handle, etc. In other embodiments, the input device may also be used on transportation vehicles such as ships, airplanes, trains, or other large equipment. For simplicity, the following description of the input device of the present application takes the application of the input device on a vehicle as an example.

[0052] First embodiment

[0053] like Figure 2 As shown, the input device 2a of the first embodiment includes a base 31, a panel 32, an elastic clip-shaped spring 42, and a piezoelectric component 41. These components are described below.

[0054] For example, the base 31 is generally in the shape of a rectangular parallelepiped, and the panel 32 is generally in the shape of a rectangular parallelepiped that matches the base 31 and covers the base 31. From the perspective of the input device 2a as a whole, the panel 32 is opposed to the base 31 along the third direction Z (i.e., a direction generally perpendicular to the piezoelectric sheet 411). The panel 32 is adapted to reciprocate up and down along the third direction Z relative to the base 31 (this will be described below).

[0055] The panel 32 is provided with a touch portion ( Figure 2 (not shown in the figure). There are multiple touch parts, and the multiple touch parts are spaced apart from each other. In some other embodiments, the number of touch parts can also be one. The relative positions of these touch parts can be flexibly arranged according to the actual usage scenario. Depending on the application scenario of the input device, these touch parts can be used to adjust the front and rear position of the seat, adjust the height of the seat cushion, input the ambient light of the device, adjust the volume of the audio, adjust the angle of the rearview mirror, adjust the display area of ​​the electronic rearview mirror, etc.

[0056] Reference Figure 2 、 Figure 3 and Figure 4The spring plate 42 includes a resilient pressing plate 43, a mounting plate 44, and a connecting plate 45. The pressing plate 43 and the mounting plate 44 are spaced apart along the third direction Z. The connecting plate 45 extends generally along the third direction Z and is connected between the end of the pressing plate 43 and the corresponding end of the mounting plate 44. This allows the pressing plate 43 to reciprocate relative to the connecting plate 45 along the third direction Z. Alternatively, the spring plate 42 (i.e., the pressing plate 43, the mounting plate 44, and the connecting plate 45) may be integrally formed. For example, the spring plate may be formed by bending spring steel, which facilitates its manufacture. Of course, depending on practical circumstances, the spring plate may also be made of other materials, such as resilient stainless steel or a resilient plastic sheet. Alternatively, the mounting plate and the connecting plate may be integrally formed, with the pressing plate formed separately and then assembled to form the spring plate. Alternatively, the mounting plate, the connecting plate, and the pressing plate may each be formed separately and then assembled together to form the spring plate. Depending on the actual situation, the connecting plate can be elastic or rigid, as long as the pressing plate has sufficient elasticity. Alternatively, the ends of the pressing plate and the mounting plate can be directly connected (for example, the pressing plate and the mounting plate generally form a V-shape), so that the spring plate does not need to include a connecting plate. For simplicity, the technical solution of this application is described using an example in which the spring plate is formed by bending spring steel and includes a pressing plate, a mounting plate, and a connecting plate.

[0057] The pressing plate 43 is generally long and narrow in shape, matching the rectangular base 31 and the rectangular panel 32. Figure 3 and Figure 4 The pressing plate 43 has a first end 430 and a second end 439 that are opposite to each other along a first direction X (i.e., the longitudinal direction of the pressing plate 43). Furthermore, the pressing plate 43 includes a first section 431 and a second section 432 located between the first end 430 and the second end 439, and a pressure transmitting portion 433 located between the first section 431 and the second section 432. The first section 431 is adjacent to the first end 430, and the second section 432 is adjacent to the second end 439. The pressure transmitting portion 433 corresponds to the piezoelectric sheet 411 described below along the third direction Z.

[0058] like Figure 4 As shown, the mounting plate 44 includes a bearing portion 443 corresponding to the pressure-transmitting portion 433 along the third direction Z, and a connecting portion 442 corresponding to the second section 432. In one embodiment, a plurality of first mounting holes 437 are provided around the bearing portion 433; mounting holes (not shown) corresponding to these first mounting holes 437 are provided on the base 31. In this manner, bolts can be used to secure the mounting plate 44 to the base 31.

[0059] The connecting plate 45 is connected between the second end 439 of the pressing plate 43 and the corresponding end of the mounting plate 44. From the perspective of the entire spring 42, the second end 439 of the pressing plate 43 is fixed, giving the pressing plate 43 a generally cantilevered structure. The first end 430 of the pressing plate 43 is adapted for reciprocating motion along the third direction Z. Of course, the first section 431, second section 432, and pressure-transmitting portion 433 of the pressing plate 43 are also adapted for reciprocating motion along the third direction Z.

[0060] The panel 32 is located on a side of the pressing plate 43 away from the mounting plate 44 and is connected to the pressing plate 43 (for example, the panel 32 is connected to the first section 431 and / or the first end 430 of the pressing plate 43). Because the first section 431 and the first end 430 of the pressing plate 43 can reciprocate along the third direction Z, the panel 32 can also reciprocate along the third direction Z driven by the pressing plate 43.

[0061] The piezoelectric assembly 41 includes a piezoelectric sheet 411, a first circuit board (not shown), and a first wiring harness (not shown). The first wiring harness electrically connects the piezoelectric sheet 411 to the first circuit board so that the piezoelectric sheet 411 and the first circuit board can communicate.

[0062] like Figure 2 and Figure 3 As shown, the piezoelectric sheet 411 is mounted on the bearing portion 443 of the mounting plate 44 so that the pressure-transmitting portion 433 corresponds to the piezoelectric sheet 411 along the third direction Z. In this way, the pressure-transmitting portion 433 can move toward and away from the piezoelectric sheet 411 along the third direction Z. In one embodiment, the piezoelectric sheet is made of piezoelectric ceramics. Piezoelectric ceramics are well known to those skilled in the art and will not be described in detail here. Of course, depending on actual conditions, the piezoelectric sheet can also be made of other suitable materials, which is not limited here. The shape of the piezoelectric sheet can be circular, rectangular, square, etc., which can be determined according to actual conditions and is not limited here.

[0063] According to the input device 2a of the present application, when no pressure is applied to the touch portion of the panel 32 (for example, no touch operation is applied to the touch portion), the pressure transmission portion 433 does not trigger the piezoelectric component 41. In this case, the pressure transmission portion may contact or slightly press the piezoelectric sheet without triggering the piezoelectric component. Alternatively, the pressure transmission portion may be spaced apart from the piezoelectric sheet.

[0064] When pressure is applied to the touch portion (i.e., a touch operation is applied to the touch portion), the panel 32 is pressed along the third direction Z and moves toward the base 31. Under the pressure of the panel 32, the first section 431 of the pressing plate 43 also bends along the third direction Z toward the mounting plate 44, driving the pressure transmitting portion 433 to press the piezoelectric sheet 411. The piezoelectric component 41 is triggered in response to the touch operation (i.e., the piezoelectric component generates a control signal). A corresponding electronic device (not shown) can perform an action in response to the control signal.

[0065] After the piezoelectric assembly 41 is triggered, the piezoelectric sheet 411 can be stimulated (for example, by applying an appropriate voltage to the piezoelectric sheet 411) to cause the piezoelectric sheet 411 to change size. This causes the piezoelectric sheet 411 to vibrate the pressing plate 43, which in turn causes the panel 32 to vibrate, so that the user can feel vibration feedback of the touch operation at the touch portion of the panel 32.

[0066] It can be seen from this that the input device 2a of the present application can not only realize the touch function, but also provide vibration feedback for the touch operation. In this way, the input device 2a does not need to be additionally provided with a vibrator as in the prior art, which reduces the number of parts required for the input device 2a, reduces the cost of the input device 2a, and simplifies the structure of the input device 2a. Moreover, the input device 2a of the present application forms a module. When installing the input device on the vehicle, it is only necessary to consider the connection between the input device and the vehicle body, and there is no need to consider the matching relationship of the parts of the input module itself, which facilitates the use of the input device. It should be understood that, according to actual conditions, the input device of the present application may also not have a base and / or panel (the base and / or panel can be served by structural parts of the vehicle body), which will not be described in detail here.

[0067] In some embodiments, the input device may also be configured so that when the piezoelectric sheet is pressed by the pressure-transmitting portion (i.e., a touch operation is applied to the touch portion on the panel), the piezoelectric component is triggered in response to the touch operation (i.e., the piezoelectric component generates a control signal); however, the piezoelectric sheet is not excited, and there is no vibration feedback at the touch portion on the panel. In other embodiments, the input device may also be configured so that, according to actual conditions, when the piezoelectric component is not triggered and the corresponding electronic device generates an execution action based on other reasons (not the control signal generated by the piezoelectric component), the piezoelectric sheet is also excited and vibration feedback is provided at the touch portion on the panel. For simplicity, the technical solution of the present application is described by taking an input device that can not only realize the touch function but also provide vibration feedback for the touch operation as an example.

[0068] Also like Figure 3As shown, in the input device 2a, the pressing plate 43 forms a lever structure with the second end 439 as a fulcrum, the pressure transmission part 433 as a first force application point, and the first end 430 (or the first section 431) as a second force application point. When the panel 32 is pressed, the first end 430 of the pressing plate 43 is pressed. According to the lever action, the pressure exerted by the pressure transmission part 433 on the piezoelectric piece 411 is greater than the pressure exerted on the first end 430, which achieves the purpose of triggering the piezoelectric component with a smaller force. When the piezoelectric piece 411 is excited to vibrate, according to the lever action, the amplitude at the first end 430 is greater than the amplitude at the pressure transmission part 433, and the amplitude of the panel 32 is also larger, so that the vibration feedback felt by the user at the touch part on the panel 32 is also stronger.

[0069] Since the pressing plate 43 and the panel 32 transmit pressing force and vibration, the piezoelectric sheet 411 and the touch portion on the panel 32 can be aligned along the third direction Z or not, which facilitates the manufacture of the input device 2a.

[0070] Reference Figure 2 and Figure 3 , the panel 32 includes an active part 321 and a passive part 322 that deviates from the active part 321. The touch part is within the range of the passive part 322. The active part 321 is fixedly connected to the first end 430 (or the first section 431) of the pressing plate 43. For example, the active part directly abuts the first end of the pressing plate, or it can be fixedly connected by screws or rivets, or it can be welded together, or fixedly connected together by a rigid connecting rod. The passive part 322 is connected to the base 31 through an elastic member 324. In this way, the panel 32 can still reciprocate substantially along the third direction Z relative to the base 31, but cannot be shifted in a direction substantially parallel to the pressing plate 43 to avoid damage to the input device 2a. In one embodiment, the elastic member 324 is a substantially C-shaped elastic plate. Depending on the actual situation, the elastic member can also be in other forms, such as elastic rubber nails, etc., which are not limited here.

[0071] It should be understood that if the panel is easily bendable (for example, the panel is a plastic plate with a thickness between 1 mm and 5 mm), the passive portion of the panel can also be connected to the base via a rigid connector (for example, a screw). When the panel is pressed, the panel can bend and deform, causing the pressing plate to also bend and deform, thereby triggering the piezoelectric component; when the piezoelectric element is excited to vibrate, the panel can also be driven by the pressing plate to vibrate, thereby providing vibration feedback.

[0072] Also according to the input device 2a of the present application, the second section 432 of the pressing plate 43 has a lower stiffness than the first section 431. For example, when equal specific forces are applied to the first and second sections along the third direction, the deformation of the second section is greater than that of the first section. This allows the user to apply relatively little force to the panel 32 while still experiencing significant bending deformation in the second section 432 of the pressing plate 43. This allows the pressure-transmitting portion 433 to press the piezoelectric sheet 411 and trigger the piezoelectric assembly 41, facilitating the use of the input device 2a. When the piezoelectric sheet 411 is stimulated to vibrate, the pressing plate 43 vibrates. Due to the greater stiffness of the first section 431, it absorbs little vibration and instead primarily drives the panel 32 to vibrate. This results in a more intense vibration of the panel 32, providing the user with excellent vibration feedback.

[0073] In addition, since the first section 431 has a greater rigidity, the first section 431 is less likely to undergo plastic deformation after the input device 2 a is used for a long time, thereby extending the service life of the input device 2 a.

[0074] In one embodiment, Figure 4 As shown, along a second direction Y (i.e., the width of the pressing plate 43) that is substantially perpendicular to the first direction X, the dimensions of the first section 431 are larger than those of the second section 432. This helps ensure that the first section 431 has greater rigidity than the second section 432. The specific widths of the first section and the second section can be determined based on practical application and are not limited herein. Furthermore, the thickness of the first section 431 can be greater than that of the second section 432. This also helps ensure that the first section 431 has greater rigidity than the second section 432 and helps reduce the weight of the input device. Similarly, the specific thicknesses of the first section and the second section can be determined based on practical application and are not limited herein.

[0075] Also like Figure 4 As shown, a rigid folded structure 434 is disposed within the first section 431, and the folded structure 434 extends generally along the second direction Y. For example, the folded structure has a corner of approximately 90 degrees. The folded structure 434 acts similarly to a deformation reinforcement on the first section 431, thereby helping to increase the rigidity of the first section 431.

[0076] In one embodiment, a plurality of reinforcing ribs 435 are provided at the corners of the bending structure 434. For example, the reinforcing ribs connect two adjacent bending surfaces of the bending structure. These reinforcing ribs support the two adjacent bending surfaces of the bending structure, which helps further increase the rigidity of the first section 431.

[0077] Also like Figure 3 and Figure 4As shown, a portion of the second section 432 away from the first section 431 is provided with a generally U-shaped elastic fold 402. The fold 402 generally extends along the second direction Y, and the opening of the fold 402 faces away from the piezoelectric plate 411 (or the mounting plate 44). The fold 402 is easily elastically deformed, thereby reducing the rigidity of the second section 432.

[0078] Also like Figure 4 As shown, the connecting plate 45 is also provided with a weakening structure 451. For example, the weakening structure 451 is a plurality of weakening grooves extending generally along the third direction Z. The weakening structure 451 reduces the rigidity of the connecting plate 45. When the first section 431 of the pressing plate 43 is pressed, the connecting plate 45 may also bend accordingly, causing the pressure-transmitting portion 433 of the pressing plate 43 to move a greater distance along the third direction Z, thereby making it easier to press the piezoelectric plate 411. In addition, the reduced rigidity of the connecting plate 45 also causes the pressing plate 43 to vibrate more strongly when the piezoelectric plate 411 vibrates. This also results in a stronger vibration of the panel 32, allowing the user to experience good vibration feedback. In one embodiment, these weakening grooves are hollowed out to further reduce the rigidity of the connecting plate. Of course, depending on the actual situation, these weakening grooves can also extend in other directions (for example, in a direction generally parallel to the second direction Y), as long as the rigidity of the connecting plate is reduced. In some other embodiments, the weakening structure can also be implemented as multiple through holes on the connecting plate, elastic folds on the connecting plate (for example, U-shaped folds, C-shaped folds, W-shaped folds, etc.), a thickness reduction area of ​​the connecting plate, one or more notches on the edge of the connecting plate along the third direction Z, etc., which will not be repeated here.

[0079] The stiffness of the pressure-transmitting portion 433 is also greater than that of the second section 432. For example, the stiffness of the pressure-transmitting portion 433 is roughly equal to that of the first section 431. Thus, when the piezoelectric sheet 411 vibrates and drives the pressing plate 43 to vibrate, the pressure-transmitting portion 433 absorbs very little of the vibration. Consequently, the first section 431 of the pressing plate 43 vibrates more strongly, providing the user with good vibration feedback at the touch-sensitive portion of the panel 32.

[0080] Reference Figure 3 and Figure 4 The pressure transmission portion 433 is provided with a first boss 436 that protrudes toward the piezoelectric sheet 411 along the third direction Z. The first boss 436 plays a role similar to deformation reinforcement on the pressure transmission portion 433 , thereby increasing the rigidity of the pressure transmission portion 433 .

[0081] The first protrusion 436 is more protruding toward the piezoelectric sheet 411 than the rest of the pressing plate 43 (e.g. Figure 3As shown. Thus, when the panel 32 is not pressed, the first boss 436 can contact or pre-compress the piezoelectric sheet 411. The rest of the pressing plate 43 is spaced apart from the mounting plate 44. When the panel 32 is pressed (i.e., a touch operation is performed), the first section 431 (or first end 430) of the pressing plate 43 drives the pressure transmission portion 433 to immediately press the piezoelectric sheet 411 (i.e., the pressure transmission portion 433 has no idle travel along the third direction Z), causing the piezoelectric assembly 41 to be triggered. In this way, the user will not experience the unpleasant sensation of insensitive touch control of the input device 2a.

[0082] Also like Figure 3 As shown, an elastic pad 401 is provided between the piezoelectric sheet 411 and the pressure transmission part 433. In this way, when the pressure transmission part 433 presses the piezoelectric sheet 411, rigid contact between the pressure transmission part 433 and the piezoelectric sheet 411 is avoided, thereby avoiding damage to the piezoelectric sheet 411. In addition, when the vehicle vibrates, the elastic pad 401 can buffer the impact of the pressure transmission part 433 on the piezoelectric sheet 411, and also prevent damage to the piezoelectric sheet 411. In one embodiment, the elastic pad is provided on the piezoelectric sheet, for example, at the center of the piezoelectric sheet. In other embodiments, the elastic pad may also be provided on the pressure transmission part (for example, on the first boss).

[0083] Reference Figure 4 and Figure 5 , the mounting plate 44 includes a reinforcing structure 446 surrounding the bearing portion 443. The reinforcing structure 446 protrudes toward the base 31 along the third direction Z. For example, the reinforcing structure is a second boss. In one embodiment, the second boss is substantially annular. The second boss plays a role similar to deformation reinforcement on the bearing portion 443 of the mounting plate 44, thereby increasing the rigidity of the bearing portion 443. This reduces the vibration of the bearing portion 443 (or the mounting plate 44) when the piezoelectric piece 411 vibrates, and the vibration of the pressing plate 43 is correspondingly stronger, thereby helping to improve the vibration feedback felt by the user on the panel 32. When the mounting plate 44 is mounted on the base 31, the second boss contacts the base 31, and the bearing portion 443 surrounded by the second boss is spaced apart from the base 31. This avoids the bearing portion 443 colliding with the base 31 and generating noise when the piezoelectric piece 411 vibrates, thereby improving the quality of the input device 2a. It should be understood that the reinforcement structure may also be implemented as reinforcing ribs surrounding the load-bearing portion, or as a thickness-increased region, etc., which will not be described in detail here.

[0084] Also like Figure 4As shown, the mounting plate 44 is also configured with a harness accommodating portion 441 for accommodating the first harness. For example, the harness accommodating portion 441 is adjacent to the load-bearing portion 443. When the piezoelectric assembly 41 is assembled onto the mounting plate 44, at least part of the first harness is coiled and arranged in the harness accommodating portion 441. In this way, when the first harness is accidentally pulled, the first harness coiled in the harness accommodating portion will be stretched and unfolded. This avoids the connection point between the first harness and the piezoelectric sheet (not shown in the figure) from being broken (for example, the first harness and the piezoelectric sheet are pulled apart). The specific form of the harness accommodating portion can be determined according to actual conditions and is not limited here.

[0085] Also like Figure 2 As shown, the input device 2a further includes a support member 201, which abuts against the second section 432 of the pressing plate 43 along the third direction Z. For example, the support member can be a bolt. Figure 4 As shown, a second mounting hole 438 is provided on the mounting plate 44, corresponding to the second section 432 of the pressing plate 43. The support member 201 is mounted on the base 31 and extends along the third direction Z through the second mounting hole 438 to abut against the second section 432 of the pressing plate 43. During the manufacturing process of the input device 2a, the protrusion height of the support member 201 toward the second section 432 of the pressing plate 43 can be adjusted to adjust the degree of curvature of the second section 432 of the pressing plate 43 toward the mounting plate 44 along the third direction Z, thereby adjusting the degree of pre-compression of the pressure transmitting portion 433 against the piezoelectric sheet 411. It should be noted that in actual use of the input device, it is generally not necessary to adjust the pre-compression of the pressure transmitting portion against the piezoelectric sheet to avoid malfunction or damage to the input device. Of course, depending on actual circumstances, in special circumstances (for example, during maintenance of the input device), the pre-compression of the pressure transmitting portion against the piezoelectric sheet can also be adjusted using the support member.

[0086] In other embodiments not shown, the support member may also be mounted on a component that is opposite to the base along the third direction, and the support member is suitable for pressing the second section of the pressing plate toward the mounting plate along the third direction. During the manufacturing process of the input device, the support member can also be used to adjust the degree of pre-compression of the pressure transmission part on the piezoelectric sheet. In this case, there is no need to provide a second mounting hole on the mounting plate. In addition, depending on the actual situation, the support member may also be in other appropriate forms; this is not limited here. Of course, in the case where there is no need to adjust the degree of pre-compression of the pressure transmission part on the piezoelectric sheet, the input device may also be without a support member.

[0087] In one embodiment, the input device further includes a touch component ( Figure 2(not shown in the figure). The touch assembly includes a touch film and a second wiring harness electrically connected to the touch film. For example, the touch film is disposed on the inner surface of the panel facing the pressing plate and corresponds to the touch portion (i.e., the orthographic projection of the touch portion along the third direction Z is within the range of the touch film). The second wiring harness is also electrically connected to the first circuit board to enable communication between the touch film and the first circuit board.

[0088] When multiple touch-sensitive areas are provided on the panel, the touch film corresponds to each of these areas. The touch film is used to identify which touch-sensitive area has been touched, so that the corresponding electronic device responds to the touch operation. This is easily implemented by those skilled in the art and will not be further described here.

[0089] In one embodiment, the touch film is a capacitive touch film. Such touch films are well known to those skilled in the art and will not be described in detail here. Of course, other types of touch films may also be used depending on the actual situation.

[0090] Second embodiment

[0091] Figure 6 The external appearance of the input device 2b of the second embodiment is schematically shown. Figure 7 and Figure 8 The structure of the input device 2b of the second embodiment is similar to that of the input device 2a of the first embodiment. For simplicity, the following mainly describes the differences between the two.

[0092] like Figure 7 As shown, the input device 2b of the second embodiment includes a base 31, a pressing plate 43 and a piezoelectric assembly 41, but does not have a mounting plate like the input device 2a of the first embodiment.

[0093] The piezoelectric assembly 41 includes a piezoelectric sheet 411, a first circuit board 413, and a first wiring harness 412 connected between the piezoelectric sheet 411 and the first circuit board 413. The piezoelectric sheet 411 is mounted on the base 31. The first circuit board 413 can also be mounted on the base 31. An elastic pad 401 is mounted on the piezoelectric sheet 411. For example, the elastic pad 401 is located in the middle of the piezoelectric sheet 411. Alternatively, the elastic pad can be mounted on the pressing plate, depending on the actual situation.

[0094] The pressing plate 43 has a first end 430 and a second end 439 that oppose each other along a first direction X. It also includes a first section 431 and a second section 432 located between the first end 430 and the second end 439, and a pressure transmitting portion 433 located between the first section 431 and the second section 432. The first section 431 is adjacent to the first end 430, and the second section 432 is adjacent to the second end 439. The pressure transmitting portion 433 corresponds to the piezoelectric sheet 411 along the third direction Z. The second end 439 is fixedly connected to the base 31. The first end 430, the first section 431, the second section 432, and the pressure transmitting portion 433 are spaced apart from the base 31 along the third direction Z and are adapted for reciprocating motion along the third direction Z.

[0095] In one embodiment, the first section, the second section and the pressure transmission portion can also be formed separately and then assembled together to form the pressing plate, which will not be described in detail here.

[0096] like Figure 8 As shown, when using the input device 2b, a pair of hands 34 and a panel 32 are provided. The panel 32 is connected to the pair of hands 34 via an elastic member 324. For example, the elastic member can be a rubber nail. Of course, depending on the actual situation, the panel can also be connected to the base via an elastic member. Similar to the input device of the first embodiment, if the panel is easily bent, the panel and the pair of hands can also be connected via a rigid connector. The panel 32 is provided with multiple touch-sensitive portions 323.

[0097] The input device 2b is positioned between the opposing member 34 and the panel 32 along the third direction Z. The base 31 is mounted on the opposing member 34, and the panel 32 is connected to the pressing plate 43. Thus, when the panel 32 is pressed toward the pressing plate 43 along the third direction Z, the pressing plate 43 is compressed and deforms toward the base 31. When the piezoelectric sheet 411 drives the pressing plate 43 to vibrate, the pressing plate 43 can also cause the panel 32 to vibrate.

[0098] Similar to the input device 2a of the first embodiment, when the panel 32 is not pressed (i.e., no touch operation is applied to the touch portion 323), the pressure transmission portion 433 does not trigger the piezoelectric component 41. When the panel 32 is pressed (i.e., a touch operation is applied to the touch portion 323), the panel 32 and the first section 431 of the pressing plate 43 bend toward the base 31 along the third direction Z and drive the pressure transmission portion 433 to press the piezoelectric sheet 411. The piezoelectric component 41 is triggered in response to the touch operation. After the piezoelectric component 41 is triggered, the piezoelectric sheet 411 is excited to vibrate, and drives the first section 431 of the pressing plate 43 and the panel 32 to vibrate, so that the user can feel vibration feedback of the touch operation at the touch portion 323.

[0099] Also like Figure 7As shown, the second end 439 of the pressing plate 43 is mounted on the base 31 via a fastener 202. For example, the fastener is a bolt. Similar to the input device 2a of the first embodiment, during the manufacturing process of the input device 2b, the degree of pre-tensioning of the pressure transmitting portion 433 against the piezoelectric sheet 411 can be adjusted by varying the tightness of the fastener 202 on the base 31. This will not be further described here.

[0100] Also like Figure 8 As shown, the panel 32 is configured with a push rod 325 extending toward the first section 431 of the pressing plate 43. The push rod 325 abuts the first section 431 (or first end 430) of the pressing plate 43, thereby achieving engagement between the panel 32 and the pressing plate 43 (or the first section 431 of the pressing plate 43). Depending on the actual situation, the push rod can also be provided on the first section or first end of the pressing plate, which will not be further described here.

[0101] The push rod 325 is spaced apart from the pressure transmission portion 433 along the first direction X. Taking the example of the push rod 325 engaging the first end 430 of the pressing plate 43, the pressing plate 43 forms a lever structure, generally with the second end 439 as the fulcrum, the pressure transmission portion 433 as the first force application point, and the first end 430 as the second force application point. When pressing the touch portion 323 on the panel 32, the push rod 325 presses the first end 430 of the pressing plate 43. Due to the lever action, the pressure of the pressure transmission portion 433 on the piezoelectric sheet 411 is greater than the pressure of the push rod 325 on the first end 430 of the pressing plate 43, thereby achieving the purpose of triggering the piezoelectric component with a smaller force. When the piezoelectric sheet 411 vibrates, the amplitude at the first end 430 of the pressing plate 43 is greater than the amplitude at the pressure transmission portion 433 due to the lever action. This results in a larger amplitude of vibration of the panel 23, and the vibration feedback felt by the user at the touch portion 323 is more intense.

[0102] Similar to the input device 2a of the first embodiment, since the pressing plate 43 and the panel 32 transmit pressing force and vibration, the piezoelectric sheet 411 and the touch portion 323 on the panel 32 can be aligned along the third direction Z or not, which facilitates the manufacture of the input device 2b.

[0103] It should be understood that the input device of the second embodiment may also include a panel. In this case, the panel may be connected to the base. Alternatively, the panel may not be connected to the base, but may be connected to the counterpart after the input device is installed on the vehicle.

[0104] Third embodiment

[0105] Figure 9 The input device 2c of the third embodiment is schematically shown. The structure of the input device 2c of the third embodiment is similar to that of the input device 2b of the second embodiment. For simplicity, the following mainly describes the differences between the two.

[0106] In the input device 2c of the third embodiment, a translucent mark (not shown) is provided on the touch portion 323 of the panel 32. The input device 2c further includes a light source assembly 5 for lighting the mark to guide the user's touch operation.

[0107] like Figure 9 As shown, the light source assembly 5 includes a light source lamp 51 and a light guide 52 .

[0108] The light source lamp 51 is provided on the pair of members 34 or the base 31. For example, the light source lamp may be an LED.

[0109] The light guide 52 includes a first portion 521 and a second portion 522 connected to the first portion 521. The first portion 521 is used to receive light emitted by the light source lamp 51. At least a portion of the second portion 522 extends to correspond to the touch portion 323. A light output structure 523 corresponding to the logo is constructed on the second portion 522. In this way, light propagating within the light guide 52 will be emitted from the light output structure 523 toward the corresponding logo, thereby illuminating the logo. In one embodiment, the light guide can be made of materials such as acrylic or optical fiber, which are not limited here.

[0110] Also like Figure 9 As shown, at least a portion of the second portion 522 extends between the panel 32 and the pressing plate 43, so that the second portion 522 can be connected to the first section 431 (or the first end 430) of the pressing plate 43 (for example, via the top rod 325), and the panel 32 is connected to the second portion 522. In this way, when the panel 32 is pressed, the second portion 522 of the light guide 51 bends and presses the first section 431 of the pressing plate 43, and then the pressure transmission portion 433 of the pressing plate 43 presses the piezoelectric piece 411, completing the triggering operation of the piezoelectric component 41. Similarly, when the piezoelectric piece 411 vibrates, the first section 431 of the pressing plate 43 is driven by the piezoelectric piece 411 to vibrate, and the second portion 522 of the light guide 51 vibrates accordingly, and the second portion 522 of the light guide 51 then drives the panel 32 to vibrate, so that the user can feel the vibration feedback at the touch portion 323.

[0111] In one embodiment, the panel 32 is in contact with the light-emitting structures 523. In this case, the light emitted by each light-emitting structure 523 can only illuminate the corresponding logo; the light cannot, or substantially cannot, diffuse and propagate, thus preventing the illumination of other logos. Furthermore, the contact between the panel 32 and the light-emitting structures 523 connects the panel 32 to the second portion 522 of the light guide 51. Of course, the panel and the second portion of the light guide can also be connected in other ways, which are not limited here.

[0112] In some other embodiments, the light source lamp can also be arranged on the second portion of the light guide and correspond to the logo of the touch portion. Of course, the light source lamp can also be arranged on the panel and correspond to the logo of the touch portion, so that the light guide is not required.

[0113] Figure 9 Also shown is a touch assembly 6. The touch assembly 6 includes a touch film 611, a second circuit board 612, and a second wiring harness 613 electrically connecting the touch film 611 to the second circuit board 612. For example, the touch film 611 is disposed on the inner surface of the panel 32 facing the pressing plate 43 and corresponds to the touch portion 323. In one embodiment, the second circuit board can also be integrated with the first circuit board of the piezoelectric assembly into a single unit to simplify the structure of the input device 2c.

[0114] Fourth embodiment

[0115] Figure 10 The input device 2d of the fourth embodiment is schematically shown. The structure of the input device 2d of the fourth embodiment is similar to that of the input device 2c of the third embodiment. For simplicity, the following mainly describes the differences between the two.

[0116] In the input device 2d of the fourth embodiment, the panel 32 is connected to the first section 431 of the pressing plate 43, and the panel 32 is spaced apart from the second portion 522 of the light guide 52 along the third direction Z. Thus, when the panel 32 is pressed, the pressing plate 43 bends to trigger the piezoelectric assembly 41, while the second portion 522 of the light guide 52 does not bend. When the piezoelectric plate 411 vibrates, the panel 32 and the pressing plate 43 vibrate, while the second portion 522 of the light guide 52 does not vibrate.

[0117] Fifth embodiment

[0118] Figure 11 The input device 2e of the fifth embodiment is schematically shown. Figure 11 As shown, in the input device 2e, two input devices described in the first embodiment are interconnected to match complex application environments. Of course, in the input device 2e, more input devices described in the first to fourth embodiments can also be interconnected, which will not be repeated here.
