Detailed implementation manners

[0028] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0029] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0030] The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "plurality" is two or more.

[0031] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "linkage" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0032] In the description of this specification, specific features, structures, materials, or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0033] In the related art, a display screen and a glass cover plate are provided on a knob in a vehicle. A through hole is formed in the knob, and the display screen is generally arranged inside the knob. The glass cover plate is then covered on the through hole of the knob, and there is a large gap between the glass cover plate and the display screen. Among them, during the rotation of the knob, the glass cover plate will rotate along with the rotation of the knob, while the display screen will not rotate along with the rotation of the knob.

[0034] However, due to the large gap between the glass cover plate and the display screen, the light emitted by the display screen will pass through the above gap and then pass through the glass cover plate and be emitted, and the resulting reflection and refraction phenomena will have a greater impact on the display screen, thereby causing the display screen effect viewed by the user to be poor.

[0035] Based on this, the embodiments of the present application provide a vehicle. Among them, the vehicle provided by the embodiments of the present application can be different types of vehicles. For example, the vehicle can be a fuel vehicle or a new energy vehicle.

[0036] The vehicle can include basic structures such as an engine, a chassis, and a body. Among them, the engine is the power device of the vehicle and can provide power for the vehicle to move on the ground.

[0037] The chassis can install the engine and other components of the vehicle, form the overall shape of the vehicle, and receive the power of the engine to make the vehicle move and ensure normal driving. The body can be installed on the chassis, and a passenger compartment is formed inside the body. The passenger compartment can be used for the driver and passengers to ride or load goods.

[0038] In addition, the vehicle provided by the embodiments of the present application can also include in-vehicle devices. Among them, different types of in-vehicle devices can achieve different functions. For example, the in-vehicle device can include an in-vehicle air conditioner. The in-vehicle air conditioner can be used to adjust the temperature inside the vehicle. Another example is that the in-vehicle device can include an in-vehicle audio system. The in-vehicle audio system can be used to play audio.

[0039] It is understandable that the above-mentioned vehicle-mounted devices are only used as examples. The vehicle-mounted devices in the vehicle provided in the embodiment of the present application may also be vehicle-mounted devices that realize other functions.

[0040] In order to adjust the vehicle-mounted equipment, the vehicle provided in the embodiment of the present application may further include a knob device. The knob device may be electrically connected to the vehicle-mounted equipment and may be used to control operating parameters of the vehicle-mounted equipment.

[0041] The following is a further description of the knob device provided in the embodiment of the present application. Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of the knob device 100 provided in an embodiment of the present application. Figure 2 for Figure 1 The exploded view of the knob device 100 shown in FIG. 1 may include a knob housing 10 , a display assembly 20 , a light-transmitting cover plate 30 , and a driving mechanism 40 .

[0042] like Figure 2 As shown, the knob housing 10 is provided with a mounting hole 101, and the display assembly 20 can be disposed in the mounting hole 101. The mounting hole 101 of the knob housing 10 can provide an installation space for the display assembly 20, and facilitate the installation of the display assembly 20.

[0043] For example, Figure 2 As shown, the knob housing 10 can be a hollow ring structure as a whole. At the same time, in order to facilitate the user to operate the knob housing 10 to rotate, a plurality of rib structures arranged at intervals can be formed on the outer wall of the knob housing 10.

[0044] Continue to refer to Figure 2 The display assembly 20 has a display surface 201, and the display surface 201 can be used to display images. It can be understood that when the display assembly 20 is installed in the mounting hole 101, the display surface 201 can be arranged opposite to the opening of the mounting hole 101. In this way, when the display surface 201 of the display assembly 20 displays images, the user can observe the displayed images through the mounting hole 101.

[0045] For example, Figure 2 As shown, the display assembly 20 may include a circuit board 21 and a display screen 22. The display screen 22 has the above-mentioned display surface 201. The circuit board 21 may be located on a side of the display screen 22 away from the display surface 201 and connected to the display screen 22. The circuit board 21 may realize signal input to the display screen 22 so that the display screen 22 displays images.

[0046] The light-transmitting cover plate 30 may be bonded to the display surface 201. The light-transmitting cover plate 30 may protect the display assembly 20. For example, Figure 1As shown, the light-transmitting cover plate 30 can be covered on the mounting hole 101 of the knob housing 10( Figure 2 ), and the mounting hole 101 is blocked. In this way, the light-transmitting cover plate 30 can prevent the entry of external dust and effectively play a protective role.

[0047] Among them, as Figure 2 shown, in order to facilitate the setting of the light-transmitting cover plate 30, a support portion 1011 can be formed on the inner wall of one end of the mounting hole 101, and the support portion 1011 can be arranged around the axis of the mounting hole 101 for one week. The light-transmitting cover plate 30 can be arranged on the support portion 1011.

[0048] As Figure 2 shown, the driving mechanism 40 can be located on the side of the display component 20 away from the light-transmitting cover plate 30, and can be used to drive the knob housing 10 and the display component 20 to rotate synchronously. Thus, as the knob housing 10 rotates, the display component 20 can rotate synchronously through the driving mechanism 40, and then drive the light-transmitting cover plate 30 to rotate synchronously.

[0049] Based on this, for the knob device 100 provided in the embodiment of the present application, the mounting hole 101 on the knob housing 10 can provide a mounting position for the display component 20, so that the display component 20 can be conveniently mounted. Since the driving mechanism 40 can drive the knob housing 10 and the display component 20 to rotate synchronously, the display component 20 can rotate with the knob housing 10. In this way, the light-transmitting cover plate 30 can be directly bonded to the display surface 201, avoiding the gap between the light-transmitting cover plate 30 and the display surface 201, so that the light emitted from the display surface 201 can smoothly pass through the light-transmitting cover plate 30 and be emitted, improving the display effect of the display screen.

[0050] It can be understood that the light-transmitting cover plate 30 and the display surface 201 can be bonded with an optical transparent adhesive. The optical transparent adhesive can enable light to pass through better, thereby ensuring the display effect of the display screen.

[0051] In order to enable the light-transmitting cover plate 30 to have a better light-transmitting effect, the light-transmitting cover plate 30 can be made of glass. In this way, the picture displayed on the display surface 201 can be emitted through the light-transmitting cover plate 30. Of course, the light-transmitting cover plate 30 can also be made of other transparent materials, which is only illustrated here.

[0052] In some embodiments, as Figure 2 shown, the driving mechanism 40 can include a first connecting member 41 and a driving motor 42. At the same time, as Figure 3 shown, Figure 3This is a cross-sectional view of the knob device 100 provided by an embodiment of the present application. The first connecting member 41 is connected to the display component 20 and the knob housing 10. In this way, the display component 20 and the knob housing 10 can rotate synchronously through the first connecting member 41.

[0053] The output end of the driving motor 42 is connected to the first connecting member 41 and is used to drive the first connecting member 41 to rotate. Thus, the driving motor 42 can provide power to make the first connecting member 41 rotate, so that the knob housing 10 and the display component 20 rotate synchronously.

[0054] Based on the above solution, the knob housing 10 can be automatically rotated through the driving motor 42. In this way, when the user needs to adjust the knob housing 10, only need to control the driving motor 42 to drive the first connecting member 41 to rotate. Of course, when the driving motor 42 stops working, the user can also manually rotate the knob housing 10 to adjust the corresponding vehicle-mounted device.

[0055] It can be understood that in some other embodiments, the driving mechanism 40 may not include the driving motor 42. At this time, when it is necessary to adjust the vehicle-mounted device by using the knob device 100, the user can manually adjust the knob housing 10 to achieve the adjustment of the vehicle-mounted device.

[0056] Exemplarily, as Figure 3 shown, the driving motor 42 may include a motor main body 421 and an output shaft 422 that are connected to each other. Among them, the output shaft 422 is connected to the first connecting member 41, and the output shaft 422 is the output end of the driving motor 42. The output shaft 422 can drive the first connecting member 41 to rotate. It can be understood that Figure 3 the structure of the driving motor 42 shown is only for illustration and does not represent the actual motor structure.

[0057] In some embodiments, as Figure 3 shown, the surface of the first connecting member 41 close to the driving motor 42 has a mounting groove 411. The output end of the driving motor 42 can be located in the mounting groove 411 and is connected to the first connecting member 41.

[0058] Exemplarily, as Figure 4 shown, Figure 4 This is a schematic structural view of the first connecting member 41 provided by an embodiment of the present application. The first connecting member 41 may include a top cover 412 and a side cover 413. The side cover 413 is located on one side of the top cover 412, surrounds the top cover 412 for one week, and forms the above-mentioned mounting groove 411 with the top cover 412.

[0059] Thus, by providing the installation groove 411, the output end of the driving motor 42 can extend into the installation groove 411, thereby realizing the installation between the first connecting member 41 and the driving motor 42. The installation structure is simple, and the assembly is easier and more convenient.

[0060] It can be understood that in order for the output end of the driving motor 42 to drive the first connecting member 41 to rotate, the first connecting member 41 and the output end of the driving motor 42 can be fixedly connected. In some embodiments, as Figure 3 shown, the driving mechanism 40 may further include a fastener 43. The fastener 43 can penetrate the first connecting member 41 and be threadedly connected to the output end of the driving motor 42.

[0061] In this way, through the fastener 43, the first connecting member 41 and the output end of the driving motor 42 are relatively fixed, and the first connecting member 41 can rotate with the rotation of the output end of the driving motor 42.

[0062] Exemplarily, based on Figure 4 the first connecting member 41 shown, a fastening hole 4122 may be formed on the top cover 412 of the first connecting member 41. The fastener 43 ( Figure 3 ) can pass through the fastening hole 4122 and be threadedly connected to the output shaft 422 of the driving motor 42.

[0063] Of course, the first connecting member 41 can also be connected to the driving motor 42 in other ways, as long as the connection between the first connecting member 41 and the driving motor 42 can be realized. For example, the first connecting member 41 can also be connected to the output end of the driving motor 42 by welding.

[0064] In order to realize the connection between the first connecting member 41 and the knob housing 10. As Figure 5 shown, Figure 5 FIG. 25 is a schematic structural diagram of a knob housing 10 provided by an embodiment of the present application. In some embodiments, the inner wall of the installation hole 101 has a limiting groove 102. Correspondingly, as Figure 4 shown, a clamping portion 4131 is formed on the peripheral wall of the first connecting member 41. Exemplarily, the clamping portion 4131 may be formed on the outer wall of the side cover 413 of the first connecting member 41.

[0065] As Figure 3 shown, the clamping portion 4131 can be located in the limiting groove 102 and be clamped with the knob housing 10. Thus, by providing the clamping portion 4131 and the limiting groove 102, the detachable connection between the first connecting member 41 and the knob housing 10 can be realized.

[0066] At the same time, the knob housing 10 and the first connecting member 41 are connected in a clamping manner, which makes it easier to install and remove the knob housing 10 and the first connecting member 41. When the components inside the knob housing 10 need to be repaired, the knob housing 10 can be removed by simply separating the clamping portion 4131 from the limiting groove 102, which makes repair more convenient.

[0067] Of course, the first connecting member 41 and the knob housing 10 may also have other structures and be connected in other ways. In other embodiments, a limiting portion may be formed inside the mounting hole 101. Accordingly, a limiting groove may be formed on the peripheral side of the first connecting member 41. In this case, the knob housing 10 and the first connecting member 41 may also be connected well.

[0068] In some embodiments, Figure 5 As shown, along the circumference of the mounting hole 101, the inner wall of the mounting hole 101 is provided with a plurality of limiting grooves 102 at intervals. Figure 4 As shown, along the circumference of the first connecting member 41, a plurality of clamping portions 4131 are formed at intervals on the peripheral wall of the first connecting member 41. Through the clamping of the plurality of clamping portions 4131 with the limiting grooves 102 respectively, the connection between the first connecting member 41 and the knob housing 10 is more firmly established.

[0069] In order to achieve the connection between the display assembly 20 and the first connecting member 41, in some embodiments, as Figure 6 and Figure 7 As shown, Figure 6 This is one of the partial structural diagrams of the knob device 100 provided in the embodiment of the present application. Figure 7 The second partial structural diagram of the knob device 100 provided in the embodiment of the present application, the first connecting member 41 is provided with an avoidance hole 4121 .

[0070] Meanwhile, the driving mechanism 40 may further include a second connecting member 44. A portion of the second connecting member 44 is located on a side of the circuit board 21 away from the first connecting member 41 and is staggered with the avoidance hole 4121. Another portion of the second connecting member 44 passes through the avoidance hole 4121 and is staggered with the avoidance hole 4121.

[0071] Thus, the second connector 44 can clamp the circuit board 21 and the first connector 41 together, so that the first connector 41 and the circuit board 21 will not be separated from each other, thereby achieving the connection between the first connector 41 and the circuit board 21. For example, Figure 7 As shown, the top cover 412 may be provided with the avoidance hole 4121, and a portion of the second connecting member 44 may be located at the top cover 412 away from the circuit board 21 ( Figure 6 ) on one side and is staggered with the avoidance hole 4121.

[0072] It can be understood that, in order to ensure the connection effect of the second connecting member 44, as Figure 7 shown, by way of example, the number of the second connecting members 44 can be multiple. Through multiple second connecting members 44, the connection between the first connecting member 41 and the circuit board 21 is more reliable, so as to ensure that when the first connecting member 41 rotates, it can drive the display assembly 20 to rotate.

[0073] In addition, it can be understood that the specific structure and form of the second connecting member 44 can be designed according to the actual situation. By way of example, as Figure 6 and Figure 7 shown, the second connecting member 44 can be a sheet-like structure and is generally U-shaped.

[0074] As Figure 6 shown, in order to realize the relative fixation between the circuit board 21 and the display screen 22, the display assembly 20 can further include a third connecting member 23. The third connecting member 23 is located between the circuit board 21 and the display screen 22 and is connected to the circuit board 21 and the display screen 22. Thus, through the third connecting member 23, the circuit board 21 and the display screen 22 can be connected to each other.

[0075] It can be understood that the connection manner between the third connecting member 23 and the circuit board 21 and the display screen 22 can be selected according to the actual situation. For example, the third connecting member 23 can be adhesively bonded to the circuit board 21 and the display screen 22 respectively.

[0076] As mentioned above, since the display assembly 20 rotates with the rotation of the knob housing 10. Therefore, in order to facilitate the circuit connection of the display assembly 20, as Figure 2 shown, in some embodiments, the knob device 100 can further include a slip ring 50. The slip ring 50 can include a fixed part and a rotating part that are rotatably connected.

[0077] The fixed part can be arranged on the motor main body 421, and the rotating part can be connected to the display assembly 20. Thus, when the display assembly 20 rotates, since the rotating part is connected to the display assembly 20, the rotating part can rotate with the rotation of the display assembly 20 and can continuously maintain the connection state, so as to stably realize the circuit connection with the display assembly 20.

[0078] It can be understood that the specific structure of the above-mentioned slip ring 50 can be the same as that of a conventional slip ring structure. The specific type and composition structure are not further introduced here, and a suitable slip ring can be selected according to the actual situation.

[0079] As Figure 3As shown, in some embodiments, the output shaft 422 may be provided with a rotation hole 4221. The slip ring 50 may be disposed within the rotation hole 4221. Wherein, a part of the rotating portion of the slip ring 50 may pass through the rotation hole 4221 and be connected to the display assembly 20. Thus, by providing the rotation hole 4221 on the output shaft 422, the setting of the slip ring 50 is more convenient and the installation is easier.

[0080] In addition, in order to facilitate the connection between the rotating portion of the slip ring 50 passing through the rotation hole 4221 and the display assembly 20, as Figure 4 shown, the first connecting member 41 may be provided with a slip ring hole 4123. Wherein, the slip ring hole 4123 may be disposed opposite to the rotation hole 4221 ( Figure 3 ).

[0081] Thus, as Figure 3 shown, the rotating portion of the slip ring 50 can be more conveniently connected to the circuit board 21 of the display assembly 20 to achieve the circuit connection of the circuit board 21. Of course, the connecting portion of the slip ring 50 can also cross the first connecting member 41 from the peripheral side of the first connecting member 41 and be connected to the circuit board 21.

[0082] Since the display assembly 20 rotates with the knob housing 10, the display surface 201 will also rotate accordingly. In order to prevent the picture displayed on the display surface 201 from rotating, in some embodiments, the display assembly 20 further includes a sensor and a controller (both not shown in the figure).

[0083] Wherein, the sensor is disposed on the circuit board 21 and is used to detect the rotation angle of the display assembly 20. The controller is disposed on the circuit board 21 and is connected to the sensor. The controller is used to control the display picture of the display screen 22 according to the angle change detected by the sensor.

[0084] During the rotation of the circuit board 21, the sensor can detect the rotation angle of the circuit board 21. Since the circuit board 21 and the display screen 22 are connected to each other and have the same rotation angle, the rotation angle of the display surface 201 of the display screen 22 can be known. At this time, the controller can adjust the picture displayed on the display surface 201 according to the rotation angle detected by the sensor, so that the display picture remains in a non-rotating state for normal display.

[0085] The type of the above sensor can be selected according to the actual situation as long as it can detect the rotation angle. For example, the sensor can be one of a magnetic sensor, an optical angle sensor or a gyroscope sensor.

[0086] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims described above.
