[0010] Another embodiment of this application provides an interactive device in which a first limiting surface arranged in an annular shape helps to increase the contact area between the substrate and the fixing part.

The base plate of the interactive device is directly connected to the vehicle body panel. Vibration transmission does not need to pass through the shell, the vibration transmission path is shorter, and the vibration attenuation during the transmission process is smaller. This helps the sensor to detect weak vibrations and improves the detection sensitivity of the interactive device, so as to improve the accuracy and sensitivity of human-computer interaction.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0027] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0028] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0029] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0030] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0031] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0032] This application provides a means of transportation, which refers to a vehicle that uses electricity, fuel, or hybrid power as its driving force to transport people or goods. The means of transportation can be a land vehicle, a marine vehicle, or an aerospace vehicle. Land vehicles include passenger cars, freight vehicles, sport utility vehicles (SUVs), and rail trains; marine vehicles include cargo ships, passenger ships, speedboats, and submersibles; and aerospace vehicles include airplanes and spacecraft. In some examples of this application, the means of transportation include new energy vehicles.

[0033] In some technical solutions, the vehicle includes a support structure and an interactive device disposed on the support structure. The interactive device includes a housing and a sensing component. Vibration is transmitted between the support structure and the sensing component through the housing. Especially when the sensing component includes a sensor and a substrate, the vibration transmission needs to pass through the support structure, the housing, the substrate, and the sensor, resulting in a relatively long vibration transmission path between the support structure and the sensor.

[0034] Therefore, embodiments of this application also provide an interactive device, referring to... Figure 1 , Figure 2 , Figure 3 and Figure 4 The interactive device includes a housing 100 and a sensing component 200. The housing 100 includes a receiving cavity 110 and an opening 111 communicating with the receiving cavity 110. The sensing component 200 is disposed in the receiving cavity 110 and includes a substrate 210 and a sensing element 220. The sensing element 220 is connected to the substrate 210 and is used to detect vibration. The substrate 210 is disposed at the opening 111 and is used to connect to an external support structure 800 and to transmit vibration between the support structure 800 and the sensing element 220.

[0035] In this embodiment, the outer surface of the housing 100 can be a regular or irregular shape such as square, circle, ellipse, triangle, trapezoid, or rhombus. The housing 100 can be a one-piece structure or a split structure.

[0036] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5In some examples, the housing 100 includes a base shell 140 and an end cap 150. The base shell 140 has openings 111 on both opposite sides. The end cap 150 covers one of the openings 111, and the base plate 210 is disposed in the other opening 111. The housing 100 and the end cap 150 together form a receiving cavity 110. The housing 100 and the end cap 150 can be detachably connected by snap-fit, threaded connection, fastener connection, or other means, so that when the interactive device is installed on the support structure 800, the sensing components 200 and the like within the receiving cavity 110 can be maintained.

[0037] In some examples, a sealing structure is provided between the base shell 140 and the end cap 150, such as sealing packing, sealing protrusion, sealing gasket, sealing ring, etc. Among them, the sealing gasket, sealing ring, etc. can be elastic structures.

[0038] It should be noted that the sensing component 200 is disposed in the receiving cavity 110. This can be achieved by the sensing component 200 being entirely disposed within the receiving cavity 110. For example, the surface of the substrate 210 facing the support structure 800 is flush with the surface of the housing 100 facing the support structure 800; alternatively, the surface of the substrate 210 facing the support structure 800 is recessed relative to the surface of the housing 100 facing the support structure 800, and the connecting structure (e.g., connector 300) between the support structure 800 and the substrate 210 extends into the receiving cavity 110 and connects to the substrate 210. The sensing component 200 can also partially protrude from the housing 100 to facilitate connection between the substrate 210 and the support structure 800.

[0039] In this embodiment, the sensing component 200 is used to detect vibration. The sensing component 200 can be a piezoelectric vibrator, a magnetostrictive vibrator, etc. For example, the sensing component 200 is a piezoelectric vibrator. The sensing component 200 includes a substrate 210 and a sensing element 220. The sensing element 220 includes one or more layers of piezoelectric ceramic. The substrate 210 transmits the vibration of the support structure 800 to the piezoelectric ceramic. The piezoelectric ceramic deforms with the vibration and generates an electrical signal under piezoelectric action.

[0040] In this embodiment, the substrate 210 is disposed at the opening 111, that is, at least a portion of the wall surface of the substrate 210 is disposed relative to the inner wall of the opening 111. The substrate 210 and the inner wall of the opening 111 can be connected or disposed at intervals.

[0041] In this embodiment, the substrate 210 is connected to the support structure 800. While ensuring that the vibration of the support structure 800 can be transmitted to the substrate 210, the two can be connected by non-removable methods such as bonding or welding, or by detachable methods such as snap-fit ​​or fastener connection.

[0042] In this embodiment, the support structure 800 can have various possible examples depending on the placement of the interactive device. For example, when the interactive device is installed on an electronic device, the support structure 800 can be the motherboard, shell, screen, etc. of the electronic device; when the electronic device is installed on a vehicle or other means of transportation, the support structure 800 can be the vehicle body. For example, the vehicle body can include the outer shell panel (such as body sheet metal), interior panel or flexible surface, vehicle components (such as seats, armrest box, bumper shell 100, steering wheel, etc.).

[0043] The interactive device of this application embodiment has a housing 100 including a receiving cavity 110. A sensing component 200 is disposed in the receiving cavity 110. The housing 100 provides protection for the sensing component 200. The sensing component 200 includes a substrate 210 and a sensor 220. The substrate 210 provides support for the sensor 220 and transmits vibration. The sensor 220 is used to detect vibration so that the interactive device can be used as an input device for human-computer interaction.

[0044] Based on this, the housing 100 is also provided with an opening 111, which connects the receiving cavity 110 to the outside. The substrate 210 is disposed at the opening 111. The substrate 210 is used to connect with the support structure 800 and can transmit vibration between the support structure 800 and the sensing element 220. Compared with the solution where the substrate 210 is connected to the housing 100 and the housing 100 is connected to the support structure 800, in the technical solution of this application, the substrate 210 is directly connected to the support structure 800. Vibration transmission does not need to pass through the housing 100. The vibration transmission path is shorter and the vibration attenuation during the transmission process is smaller. This helps the sensing element 220 detect weak vibrations and improves the detection sensitivity of the interactive device, so as to improve the accuracy and sensitivity of human-computer interaction.

[0045] To improve the connection stability and vibration transmission accuracy of the interactive device, refer to Figure 1 , Figure 2 and Figure 4 In some embodiments of this application, the interactive device further includes a connector 300, which includes a first connecting portion 310, and the first connecting portion 310 is respectively attached to the substrate 210 and the support structure 800.

[0046] In some examples, connector 300 is an adhesive filler, such as glue, which bonds connector 300 to support structure 800 after curing; in other examples, connector 300 is double-sided tape, which bonds connector 300 to support structure 800 respectively; in still other examples, connector 300 is a welding filler, so as to weld connector 300 to support structure 800.

[0047] In some examples, the portion of the substrate 210 facing the support structure 800 is attached to the first connection portion 310; in other examples, the entire surface of the substrate 210 facing the support structure 800 is attached to the first connection portion 310, that is, the entire surface of the substrate 210 is attached to the support structure 800, resulting in better vibration transmission.

[0048] In the interactive device of this application embodiment, the first connecting portion 310 of the connector 300 is attached to the substrate 210 and the support structure 800 respectively. On the one hand, it improves the connection stability between the substrate 210 and the support structure 800, which helps to fix the sensing component 200 relative to the support structure 800. On the other hand, it helps to transmit vibration between the substrate 210 and the support structure 800, so as to improve the sensitivity of vibration detection.

[0049] For the stability and sealing of the interactive device connection, refer to Figure 1 , Figure 2 and Figure 4 In some embodiments of this application, the connector 300 further includes a second connecting portion 320, which surrounds the first connecting portion 310 and is respectively attached to the housing 100 and the support structure 800.

[0050] In some examples, the first connecting portion 310 and the second connecting portion 320 are spaced apart, that is, there is a gap between the first connecting portion 310 and the second connecting portion 320; in other examples, the first connecting portion 310 and the second connecting portion 320 are integrally formed (the dashed lines in the figure are used to clarify the relative positions of the first connecting portion 310 and the second connecting portion 320, which are actually an integral structure).

[0051] In some examples, the second connecting part 320 is a ring structure, and its ring outline can be circular, elliptical, square, triangular, rhomboid, etc.; in other examples, there are multiple second connecting parts 320, and multiple second connecting parts 320 are arranged in sequence to form a ring structure.

[0052] In the interactive device of this application embodiment, the second connecting portion 320 of the connector 300 is attached to the housing 100 and the support structure 800 respectively. On the one hand, the housing 100 is fixed to the support structure 800, which improves the connection stability between the interactive device and the support structure 800. On the other hand, the second connecting portion 320 surrounds the first connecting portion 310. The attachment of the second connecting portion 320 to the housing 100 helps to seal the receiving cavity 110, thereby improving the waterproof and dustproof performance of the interactive device.

[0053] To improve the connection stability between the substrate 210 and the support structure 800, refer to Figure 2 , Figure 4 and Figure 6In some embodiments of this application, the housing 100 further includes a fixing part 120, which is located in the receiving cavity 110. The fixing part 120 includes a first limiting surface 121 facing the opening 111, and the substrate 210 abuts against the first limiting surface 121.

[0054] In some examples, the fixing part 120 is disposed on the inner wall of the base shell 140 and the fixing part 120 does not contact the end cap 150; in other examples, the fixing part 120 is disposed on the end cap 150 and the fixing part 120 does not contact the base shell 140.

[0055] In some examples, the fixing part 120 is disposed corresponding to the edge of the substrate 210, and there is a gap between the fixing part 120 and the sensing element 220 along the extension direction of the substrate 210 (perpendicular to the preset direction X shown in the figure).

[0056] In some examples, the fixing part 120 is provided on one or more sides of the substrate 210; in other examples, there are multiple fixing parts 120, and one or more fixing parts 120 are provided on each side of the substrate 210.

[0057] In the interactive device of this application embodiment, a fixing part 120 is provided in the receiving cavity 110. A first limiting surface 121 is provided on the side of the fixing part 120 facing the opening 111. The first limiting surface 121 abuts against the substrate 210, thereby restricting the substrate 210 from moving toward the inside of the receiving cavity 110, so as to press the substrate 210 onto the support structure 800, which helps the substrate 210 and the support structure 800 to maintain a stable connection.

[0058] To improve the structural stability of the interactive device, refer to Figure 2 and Figure 4 In some embodiments of this application, the housing 100 further includes an extension 130 having a second limiting surface 131 forming a portion of the inner wall of the receiving cavity 110, and the second limiting surface 131 surrounding the substrate 210, with the substrate 210 abutting against the second limiting surface 131.

[0059] In some examples, the second limiting surface 131 is an arc-shaped surface, for example, the second limiting surface 131 forms a ring structure; in other examples, the second limiting surface 131 includes multiple planes, which are connected end to end to form a ring structure such as a square, triangle, or rhombus.

[0060] In some examples, the size of the second limiting surface 131 is different from the size of the substrate 210 along the direction perpendicular to the first limiting surface 121 (e.g., the preset direction X shown in the figure); in other examples, the size of the second limiting surface 131 is the same as the size of the substrate 210 along the direction perpendicular to the first limiting surface 121.

[0061] In the interactive device of this application embodiment, the second limiting surface 131 of the extension 130 forms part of the inner wall of the receiving cavity 110, and the second limiting surface 131 surrounds the sensing element 220. The second limiting surface 131 abuts against the substrate 210 to restrict the movement of the substrate 210 relative to the housing 100 along the connection surface (perpendicular to the preset direction X) of the substrate 210 and the support structure 800, so that the substrate 210 and the housing 100 can maintain a relative position and improve the structural stability of the interactive device.

[0062] To improve the structural stability of the interactive device, refer to Figure 2 and Figure 4 In some embodiments of this application, the housing 100 includes at least two limiting surfaces, which are arranged at an angle. The substrate 210 abuts against the limiting surfaces, and the substrate 210 is fixedly connected to the structure corresponding to at least one limiting surface.

[0063] In this embodiment, the limiting surface has various possible orientations. For example, the second limiting surface 131 on the extension 130 is parallel to the preset direction X; or the first limiting surface 121 on the fixing part 120 is perpendicular to the preset direction X. Furthermore, other surfaces in the housing 100 that can abut against the substrate 210 can also be limiting surfaces. It should be noted that the angle between the limiting surface and the preset direction X can also be an acute angle or an obtuse angle.

[0064] In this embodiment of the application, the substrate 210 can be fixed to the structure corresponding to the limiting surface. For example, the substrate 210 is fixedly connected to the extension 130 corresponding to the second limiting surface 131; and / or, the substrate 210 is fixedly connected to the fixing part 120 corresponding to the first limiting surface 121.

[0065] In some examples, the substrate 210 is fixedly connected to the extension 130, and the substrate 210 is not connected to the fixing part 120; in other examples, the substrate 210 is fixedly connected to the fixing part 120, and the substrate 210 is not connected to the extension 130; in still other examples, the substrate 210 is connected to both the fixing part 120 and the extension 130.

[0066] In some examples, the substrate 210 and the extension 130 are connected by non-removable means such as bonding or welding; in other examples, the substrate 210 and the extension 130 are connected by detachable means such as snap-fit ​​or threaded connection.

[0067] In some examples, the substrate 210 and the fixing part 120 are connected by non-removable means such as bonding or welding; in other examples, the substrate 210 and the fixing part 120 are connected by detachable means such as snap-fit ​​or threaded connection.

[0068] The interactive device of this application embodiment has at least two limiting surfaces that can limit the substrate 210 from different directions, and the substrate 210 is fixed to the structure corresponding to at least one limiting surface. On the one hand, this can improve the structural stability of the interactive device; on the other hand, it can seal the gap between the substrate 210 and the limiting surface, thereby improving the sealing performance of the receiving cavity 110. For example, if the substrate 210 is fixedly connected to the extension 130, the substrate 210 can be fixed relative to the housing 100, improving the structural stability of the interactive device and the sealing performance of the receiving cavity 110. As another example, if the substrate 210 is fixedly connected to the fixing part 120, the substrate 210 can be fixed relative to the housing 100, improving the structural stability of the interactive device and the sealing performance of the receiving cavity 110. As yet another example, if the substrate 210 is fixedly connected to both the extension 130 and the fixing part 120, it helps to improve the structural stability of the interactive device and the sealing performance of the receiving cavity 110.

[0069] To improve the connection stability between the substrate 210 and the housing 100 and the sealing performance of the receiving cavity 110, refer to Figure 6 In some embodiments of this application, the first limiting surface 121 is arranged in a ring shape, and the edge region of the substrate 210 is connected to the first limiting surface 121.

[0070] In some examples, the inner contour of the first limiting surface 121 is adapted to the outer contour of the sensor 220, for example, both are circular or square; in other examples, the inner contour of the first limiting surface 121 is different from the outer contour of the sensor 220.

[0071] In some examples, the edge region of the substrate 210 refers to the region that includes the outer contour of the substrate 210 and has a gap with the sensing element 220, so as to avoid interference between the fixing part 120 and the sensing element 220.

[0072] The interactive device of this application embodiment has a first limiting surface 121 arranged in a ring shape, which helps to increase the contact area between the substrate 210 and the fixing part 120. On the one hand, it can improve the connection stability between the substrate 210 and the housing 100; on the other hand, it can prevent water vapor, dust and the like from entering the receiving cavity 110, thereby improving the sealing and protection performance of the receiving cavity 110.

[0073] To simplify the structure and facilitate wiring, refer to... Figure 2 and Figure 3 In some embodiments of this application, the interactive device further includes a first conductive element 400, the housing 100 includes an interface portion 500 for electrically connecting to an external circuit; the sensing element 220 includes a first conductive portion 221 and a second conductive portion 222, the first conductive portion 221 and the second conductive portion 222 having different polarities.

[0074] For example, the first conductive part 221 is a positive conductive part and the second conductive part 222 is a negative conductive part; or, the first conductive part 221 is a negative conductive part and the second conductive part 222 is a positive conductive part.

[0075] The first conductive part 221 and the second conductive part 222 may be one or more, for example, the sensing element 220 includes a single first conductive part 221 and a single second conductive part 222.

[0076] In some examples, the first conductive element 400 is a conductive post, such as a spring pin; in other examples, the first conductive element 400 is a conductive sheet; and in still other examples, the first conductive post is a conductive wire harness.

[0077] In this embodiment, the interface portion 500 is used for electrical connection to an external circuit. For example, the interface portion 500 is connected to a vehicle terminal, or the interface portion 500 is connected to a vibration signal analysis circuit.
