[0038] Reference below Figure 1-Figure 5 The key assembly 100 according to the embodiment of the present invention is described. By setting the display screen component 1, the key function can be displayed, and the visualization of the key function can be realized, so that the user can perform further operations and reduce the possibility of user misoperation. The key shell 2 is connected to the key keycap 3 and the display screen component 1 at the same time, so that the key assembly 100 can be a whole, which can improve the overall stability and reliability of the key assembly 100. At the same time, the floating setting of the key keycap 3 can extend the service life of the key keycap 3. In addition, after the user presses the key keycap 3 to make the key keycap 3 close to the display screen component 1, the display screen component 1 will trigger the key function corresponding to the key keycap 3, so that the user can perform subsequent operations.

[0039] like Figure 1 As shown, a key assembly 100 according to an embodiment of the present invention includes: a display screen assembly 1, a key housing 2 and a key cap 3.

[0040] The button housing 2 is connected to the display screen assembly 1; the button keycap 3 is movably installed on the button housing 2, and the button keycap 3 is set to float in a direction away from the display screen assembly 1. When the button keycap 3 is pressed, it approaches the display screen assembly 1. After the button keycap 3 approaches, the display screen assembly 1 triggers the button function corresponding to the button keycap 3, and the display screen assembly 1 displays the function logo corresponding to the button keycap 3.

[0041] Specifically, the key assembly 100 is used to trigger the key function corresponding to the key cap 3 after the user presses the key cap 3, so that the user can perform subsequent operations. The key assembly 100 includes a display assembly 1, a key shell 2 and a key cap 3, wherein the display assembly 1 is used to display the function identification corresponding to the key cap 3 to realize the visualization of the key function, which is convenient for the user to perform further operations. The key cap 3 is used to provide the user with a position for operation, that is, the user can press the key cap 3 with a finger or an object to operate the key cap 3, and the key cap 3 can provide the user with certain tactile feedback to help the user press the key cap 3 accurately without looking at the key cap 3. The key shell 2 is used to realize the installation of the key cap 3 to ensure the reliable operation of the key cap 3.

[0042] The button keycap 3 is movably installed on the button housing 2, and the button keycap 3 can be connected to the button housing 2 to achieve the installation of the button keycap 3, ensure the reliability of the button keycap 3, and make the button keycap 3 movable relative to the button housing 2, that is, when the user presses the button keycap 3, the button keycap 3 can move relative to the button housing 2. At the same time, the button housing 2 is connected to the display screen assembly 1, and the button housing 2 can be connected to the button keycap 3 and the display screen assembly 1 at the same time, so that the button assembly 100 is a whole, which can ensure the overall stability and reliability of the button assembly 100, and in actual design, the button housing 2 can be detachably connected to the display screen assembly 1, so that the display screen assembly 1 can be replaced when it is damaged and fails, which can reduce the subsequent maintenance cost.

[0043] It should be noted that, Figure 1-Figure 2 As shown, the display screen assembly 1 is arranged below the button keycap 3 . When the user presses the button keycap 3 , the button keycap 3 can move downward, that is, move toward the direction close to the display screen assembly 1 .

[0044] In addition, by setting the button keycap 3 to float in the direction away from the display screen assembly 1, a certain distance can be created between the button keycap 3 and the display screen assembly 1 to avoid the button keycap 3 from squeezing the display screen assembly 1 and causing damage and failure of the display screen assembly 1. In addition, when the button keycap 3 is under pressure, it approaches the display screen assembly 1 and triggers the key function corresponding to the button keycap 3. That is, when the user presses the button keycap 3, the button keycap 3 will move relative to the button housing 2 in the direction close to the display screen assembly 1, and after the button keycap 3 approaches the display screen assembly 1, the display screen assembly 1 will trigger the key function corresponding to the button keycap 3, so that the user can perform the next operation.

[0045] Also, it should be noted that floating the keycap 3 can reduce the connection between the keycap 3 and the surrounding structure, reduce the breakage of the connection part, extend the service life of the keycap 3, and the entire movement stroke of the keycap 3 will not contact the display assembly 1, which can ensure that the display assembly 1 will not be damaged and fail due to the extrusion of the keycap 3.

[0046] According to the key assembly 100 of the embodiment of the present invention, by setting the key cap 3, a position for the user to perform operations can be provided, the key housing 2 can be set to install the key cap 3, and the display screen assembly 1 can be set to realize the visualization of the key function, so that the user can perform further operations and reduce the possibility of user misoperation. The key housing 2 is connected to the key cap 3 and the display screen assembly 1 at the same time, so that the key assembly 100 can be a whole, which can improve the overall stability and reliability of the key assembly 100. At the same time, the floating setting of the key cap 3 can extend the service life of the key cap 3, and after the user presses the key cap 3 to make the key cap 3 close to the display screen assembly 1, the display screen assembly 1 will trigger the key function corresponding to the key cap 3, so that the user can perform subsequent operations.

[0047] In some embodiments, the keycap 3 is provided with a first magnetic component 31 and the key housing 2 is provided with a second magnetic component 21 . The keycap 3 is suitable for floating in a direction away from the display screen assembly 1 under the magnetic action of the first magnetic component 31 and the second magnetic component 21 .

[0048] Specifically, the button keycap 3 can be movably installed on the button housing 2, and the button keycap 3 is set to float in the direction away from the display screen assembly 1. A first magnetic part 31 is set on the button keycap 3, and a second magnetic part 21 is set on the button housing 2. The button keycap 3 can be suspended in the direction away from the display screen assembly 1 under the action of the first magnetic part 31 and the second magnetic part 21, that is, the button keycap 3 can be suspended relative to the button housing 2 in the direction away from the display screen assembly 1, that is, suspended upward, so that the button keycap 3 can be separated from the display screen assembly 1 and have a certain distance, thereby avoiding the button keycap 3 from squeezing the display screen assembly 1 and causing damage and failure of the display screen assembly 1.

[0049] Among them, it should be noted that the first magnetic part 31 and the second magnetic part 21 can make the button keycap 3 float upward, that is, the first magnetic part 31 and the second magnetic part 21 can be used to balance the gravity of the button keycap 3, ensuring that the button keycap 3 can be separated from the display screen assembly 1, and the first magnetic part 31 and the second magnetic part 21 can also provide the user with certain tactile feedback, helping the user to press the button accurately without looking at the button.

[0050] In some embodiments, there are multiple first magnetic parts 31, and the multiple first magnetic parts 31 are distributed at intervals in the circumferential direction of the key cap 3; there are multiple second magnetic parts 21, and the multiple second magnetic parts 21 are distributed at intervals in the circumferential direction of the key housing 2, and the multiple first magnetic parts 31 are matched with the multiple second magnetic parts 21 in a one-to-one correspondence.

[0051] Specifically, the first magnetic member 31 and the second magnetic member 21 can make the key cap 3 suspend relative to the key housing 2. The first magnetic member 31 and the second magnetic member 21 are both multiple, that is, the number of the first magnetic member 31 and the second magnetic member 21 can be two, three or more, so as to improve the reliability of the key cap 3 suspending relative to the key housing 2 through the joint action of the multiple first magnetic members 31 and the multiple second magnetic members 21. Moreover, the multiple first magnetic members 31 are matched with the multiple second magnetic members 21 in a one-to-one correspondence, that is, the number of the first magnetic members 31 and the second magnetic members 21 is the same, and for each first magnetic member 31, there is a second magnetic member 21 to cooperate with it, which can further improve the reliability of the key cap 3 suspending relative to the key housing 2.

[0052] In addition, multiple first magnetic members 31 are distributed in a spaced-apart manner in the circumferential direction of the key cap 3, that is, multiple first magnetic members 31 are evenly distributed in the circumferential direction of the key cap 3, and multiple second magnetic members 21 are distributed in a spaced-apart manner in the circumferential direction of the key housing 2, that is, multiple second magnetic members 21 are evenly distributed in the circumferential direction of the key housing 2, so that the key cap 3 can be stably suspended relative to the key housing 2 through the joint action of the first magnetic members 31 and the second magnetic members 21.

[0053] In some embodiments, the first magnetic member 31 and the second magnetic member 21 are both constructed in a ring shape, and the second magnetic member 21 is distributed around the first magnetic member 31 .

[0054] Specifically, the first magnetic part 31 and the second magnetic part 21 can make the button keycap 3 suspend relative to the button housing 2. The first magnetic part 31 and the second magnetic part 21 can be constructed into a ring shape to increase the setting length of the first magnetic part 31 and the second magnetic part 21, thereby increasing the magnetism of the first magnetic part 31 and the second magnetic part 21, and improving the reliability of the button keycap 3 suspending relative to the button housing 2 under the action of the first magnetic part 31 and the second magnetic part 21. The second magnetic part 21 is distributed around the first magnetic part 31, and the first magnetic part 31 and the second magnetic part 21 can be coaxially set, which can reduce the occupied space of the button assembly 100 and facilitate the setting of the button assembly 100.

[0055] It should be noted that, in actual design, a second magnetic component 21 can be provided on the keycap 3, and a first magnetic component 31 can be provided on the key housing 2. The first magnetic component 31 can be provided around the second magnetic component 21. The keycap 3 can also be suspended relative to the key housing 2 through the action of the first magnetic component 31 and the second magnetic component 21.

[0056] In some embodiments, the first magnetic member 31 is embedded in the keycap 3 , and / or the second magnetic member 21 is embedded in the key housing 2 .

[0057] Specifically, the button keycap 3 is provided with a first magnetic part 31, and the button housing 2 is provided with a second magnetic part 21. The button keycap 3 can be suspended relative to the button housing 2 through the first magnetic part 31 and the second magnetic part 21. The first magnetic part 31 can be embedded in the button keycap 3 to achieve the installation of the first magnetic part 31, and the first magnetic part 31 can be fixed and protected by the button keycap 3 to avoid displacement or damage of the first magnetic part 31. The second magnetic part 21 is embedded in the button housing 2 to achieve the installation of the second magnetic part 21, and the second magnetic part 21 can be fixed and protected by the button housing 2 to avoid displacement or damage of the second magnetic part 21, thereby ensuring the reliability of the button keycap 3 being suspended relative to the button housing 2 under the action of the first magnetic part 31 and the second magnetic part 21.

[0058] And, it should be noted that, Figure 1-Figure 2 As shown, the first magnetic component 31 extends in the up-down direction inside the key cap 3, and the second magnetic component 21 extends in the up-down direction inside the key housing 2, thereby increasing the setting length of the first magnetic component 31 and the second magnetic component 21, thereby increasing the magnetism of the first magnetic component 31 and the second magnetic component 21, and improving the reliability of suspending the key cap 3 relative to the key housing 2 through the first magnetic component 31 and the second magnetic component 21.

[0059] In some embodiments, the key housing 2 and the display screen assembly 1 define an active cavity 4, and the key housing 2 has an active opening 22 connected to the active cavity 4 on a side away from the display screen assembly 1. The key cap 3 can be movably installed in the active cavity 4, and at least a portion of the key cap 3 is suspended and extended from the active opening 22.

[0060] Specifically, the key housing 2 is connected to the display screen assembly 1, so that the key housing 2 and the display screen assembly 1 jointly define an active cavity 4, and the key cap 3 is movably installed in the active cavity 4, that is, the key cap 3 can be moved in the active cavity 4 relative to the key housing 2 in a direction close to the display screen assembly 1, so that the display screen assembly 1 can trigger the key function corresponding to the key cap 3, and an active opening 22 connected to the active cavity 4 is formed on the side of the key housing 2 away from the display screen assembly 1, that is, the active opening 22 is formed on the upper side of the active cavity 4, and the active cavity 4 can be connected with the outside of the active cavity 4, so that at least part of the key cap 3 can be suspended and extended from the active opening 22, that is, the key cap 3 can be extended upward from the active opening 22 under the action of the first magnetic part 31 and the second magnetic part 21 to extend toward the outside of the active cavity 4, so that the user can press it to operate it.

[0061] Among them, it should be noted that the button keycap 3 can be tightly matched with the button shell 2 to prevent particles and dust from entering the active cavity 4 through the gap between the button keycap 3 and the button shell 2, thereby ensuring the reliable movement of the button keycap 3 and the display effect of the display screen assembly 1, and allowing the button keycap 3 to move up and down along the active opening 22. Even if the active opening 22 can guide the movement of the button keycap 3, the accuracy of the movement direction of the button keycap 3 can be improved.

[0062] In some embodiments, the button housing 2 includes a mounting portion 23 and an end plate portion 24 , one end of the mounting portion 23 is connected to the display assembly 1 and the other end is connected to the end plate portion 24 to jointly define the active cavity 4 , and the active opening 22 is provided on the end plate portion 24 .

[0063] Specifically, by connecting the other end of the mounting portion 23 to the end plate portion 24, the mounting portion 23 and the end plate portion 24 can be connected, so that the key shell 2 is a whole, which can improve the overall structural strength of the key shell 2, and by connecting one end of the mounting portion 23 to the display screen assembly 1, the two ends of the mounting portion 23 can be connected to the end plate portion 24 and the display screen assembly 1 respectively, thereby realizing the connection between the key shell 2 and the display screen assembly 1, so that the mounting portion 23, the end plate portion 24 and the display screen assembly 1 can jointly define the active cavity 4, so that the key cap 3 can move relative to the key shell 2 in the active cavity 4, so that the display screen assembly 1 can trigger the key function corresponding to the key cap 3, and, by setting the active opening 22 on the end plate portion 24, the active opening 22 can be set on the side of the key shell 2 opposite to the display screen assembly 1, so that the key cap 3 can extend from the active opening 22, so that the user can press it to operate, and the key cap 3 can be prevented from squeezing the display screen assembly 1, causing damage and failure of the display screen assembly 1.

[0064] The keycap 3 includes a movable portion 32 and a limiting portion 33. The movable portion 32 is arranged in the movable opening 22 and is suitable for extending from the movable opening 22. The limiting portion 33 is connected to one end of the movable portion 32 located in the movable cavity 4. The limiting portion 33 is suitable for limiting and pressing against the end plate portion 24.

[0065] Specifically, by passing the movable portion 32 through the movable opening 22, a movable connection between the key cap 3 and the key housing 2 can be realized, so that the key cap 3 can move relative to the key housing, and the movable portion 32 is extended from the movable opening 22, that is, the movable portion 32 can extend from the inner side of the movable cavity 4 to the outer side, so that the user can press it. At the same time, by connecting one end of the movable portion 32 located in the movable cavity 4 with the limiting portion 33, the key cap 3 can be a whole, which can improve the overall structural strength of the key cap 3, and the limiting portion 33 can be limited and pressed against the end plate portion 24, that is, when the user stops pressing the key cap 3, the key cap 3 can move upward under the action of the first magnetic member 31 and the second magnetic member 21, and when it moves upward to the limit position, the upper side surface of the limiting portion 33 can be pressed and contacted with the lower side surface of the end plate portion 24 to limit the key cap 3 and prevent the key cap 3 from falling out of the movable cavity 4.

[0066] In some embodiments, the display screen assembly 1 includes a sensing component 11, a control component 12 and a display panel 13. The display panel 13 is arranged on the side of the control component 12 close to the button housing 2. The sensing component 11 and the control component 12 are electrically connected. The sensing component 11 sends a sensing signal to the control component 12 after the button keycap 3 approaches. The control component 12 outputs a trigger instruction according to the sensing signal. The display panel 13 is used to display the function identification.

[0067] Specifically, the display panel 13 is used to display the function identification corresponding to the button keycap 3, the control component 12 is used to output the trigger instruction, and the sensing component 11 is used to detect the movement of the button keycap 3. The sensing component 11 is electrically connected to the control component 12. When the button keycap 3 moves in the direction close to the display screen assembly 1, the button keycap 3 can approach the sensing component 11. At this time, the sensing component 11 can send a sensing signal to the control component 12 after detecting that the button keycap 3 is approaching. The control component 12 will output a trigger instruction according to the sensing signal to trigger the button function corresponding to the button keycap 3, so that the user can perform subsequent operations. The display panel 13 is set on the side of the control component 12 close to the button housing 2, that is, the display panel 13 is set above the control component 12 and facing the user, so that the user can observe the function identification on the display panel 13 and perform the next operation according to the button function displayed by the function identification.

[0068] Among them, it should be noted that the control component 12 can be constructed as a printed circuit board, and a central processing unit is provided in the printed circuit board. The sensing component 11 can be constructed as a Hall element, and the Hall element has a set value. When the displacement of the key cap 3 toward the Hall element is greater than the set value, a change in electrical properties will occur, such as a change in voltage or current. This change in electrical properties will be converted into an induction signal and transmitted to the printed circuit board. The central processing unit on the printed circuit board will process the induction signal and trigger the key function corresponding to the key cap 3, thereby realizing the visualization of the key function, which is convenient for the user to perform further operations. Among them, by setting the set value for the Hall element, false touches can be avoided, which is conducive to improving user satisfaction.

[0069] In some embodiments, the display screen assembly 1 also includes a shell frame 14, which forms a accommodating cavity 141. The sensing component 11 and the control component 12 are both installed in the accommodating cavity 141. The shell frame 14 is provided with a display port 142 connected to the accommodating cavity 141 on the side close to the button housing 2, and the display panel 13 is provided at the display port 142.

[0070] Specifically, the housing frame 14 is used to install and protect the sensing element 11, the control element 12 and the display panel 13. Figure 3 As shown, a accommodating cavity 141 is formed in the shell frame 14, and the sensing component 11 and the control component 12 can be both arranged in the accommodating cavity 141 to achieve the installation and fixation of the sensing component 11 and the control component 12, and the sensing component 11 and the control component 12 can be protected by the shell frame 14 to protect the sensing component 11 and the control component 12 from external physical damage.

[0075] Also, it should be noted that the button assembly 100 of the present application can be used for function prompts of button keycaps 3 with customizable functions. When the user completes the function settings of the button keycaps 3, the display screen assembly 1 can display the current button function identification of the button keycaps 3, and the button assembly 100 can be electrically connected to the vehicle-mounted application so that the button function can be switched as the vehicle-mounted application is switched.

[0076] The utility model also provides a steering wheel.

[0077] A steering wheel according to an embodiment of the present invention includes a steering wheel body and any of the aforementioned button assemblies 100. By disposing a display screen assembly 1 below the button keycaps 3, the display screen assembly 1 can display button function identifiers, thereby visualizing the button functions and reducing the possibility of user misoperation. Furthermore, the button assembly 100 can be integrated into the steering wheel body to bring it closer to the user, making it easier for the user to press the button keycaps 3 to trigger the corresponding button function of the button keycaps 3, thereby facilitating further user operations.

[0078] The utility model also provides a vehicle.

[0079] According to an embodiment of the present invention, a vehicle includes any of the above-mentioned key assemblies 100, or includes the above-mentioned steering wheel, and the display screen assembly 1 is electrically connected to the vehicle controller 201. By arranging the display screen assembly 1 below the key cap 3, the display screen assembly 1 can display the key function identifier to achieve visualization of the key function and reduce the possibility of user misoperation. In addition, the display screen assembly 1 is electrically connected to the vehicle controller 201, so that the display screen assembly 1 can send the key function signal corresponding to the current key cap 3 to the vehicle controller 201, and the vehicle controller 201 implements the key function corresponding to the key cap 3.

[0080] In practice, a button keycap 3 with customizable functions is usually set on the steering wheel of the vehicle, so that the user can customize the button function according to his or her own needs. If one button keycap 3 with customizable functions cannot meet the user's needs, multiple button keycaps 3 with customizable functions can be set at the same time, and the button function identifier corresponding to each button keycap 3 can be displayed on the corresponding display screen assembly 1 for user convenience. The user can also change the function layout of multiple button keycaps 3 at will according to his or her own habits, which can reduce the learning and adaptation costs for users of multiple models and users who change cars. Alternatively, the display screen assembly 1 can also be used for function prompts of existing multi-function rollers, multi-function levers or multi-function buttons, so that the function identifier displayed can be switched according to the switching of functions, and when new functions are launched on the vehicle OTA (Over The Air), they can be configured synchronously on the steering wheel to increase the applicability of the button assembly 100.

[0081] like Figure 4 The figure shows a control block diagram of the steering wheel. The vehicle controller 201 is electrically connected to the multimedia 202, the advanced driver assistance system 203 and the button assembly 100 respectively. The button functions of the button assembly 100 can be changed accordingly according to user settings or scene switching. The display screen component 1 sends signals to the vehicle controller 201 through the communication subnet channel. The vehicle controller 201 then controls other modules on the vehicle through the communication subnet channel to realize the button functions.

[0082] like Figure 5 The figure shows a flow chart for realizing the button function. The user can change the button function according to his or her intention or need. At this time, the display screen component 1 will display the corresponding button function logo, thereby realizing the layout update of the button function. Then, the user can press the button keycap 3, and the display screen component 1 receives the signal and sends the sensing signal to the vehicle controller 201. The vehicle controller 201 can process the signal and forward it to other networks. Other modules can work together to realize the button function on the premise of receiving the signal and judging that it is valid.
