[0035] In the embodiments of the present application, in order to facilitate the description of the direction, Figure 1 、 Figure 2 、 Figure 5 and Figure 7The three directions are respectively a first direction, a second direction and a third direction. The first direction is a length direction of the key, the second direction is a width direction of the key, and the third direction is a height direction of the key and a lifting direction of the keycap 2. The first direction, the second direction and the third direction are perpendicular to each other. It should be noted that the direction identifiers are only used to describe the present application, but not to limit the scope of the present application.
[0036] The key is a component for inputting instructions on an electronic device, and is widely used in various electronic devices. In the related art, the key can include a keycap, a scissors leg assembly and a base. The scissors leg assembly is arranged between the base and the keycap to balance the pressing force of the keycap.
[0037] When the keycap is pressed, uneven force may cause the keycap to generate transverse or lateral components. These components will affect the conduction and dispersion of the pressure, so that the scissors leg assembly may be out of balance during the opening and closing process, which may cause the scissors leg assembly to easily deviate during the opening and closing process, thereby affecting the pressing feeling of the key. In severe cases, it may even be stuck or have an uneven rebound.
[0038] To solve the above problems, an electronic device is provided in the embodiments of the present application. It should be noted that the electronic device mentioned in the embodiments of the present application can be a notebook computer, a television or a game console, and the embodiments of the present application do not limit the electronic device.
[0039] In the embodiments of the present application, the electronic device can include a device main body and a key. The key can be arranged on the device main body. Here, the device main body can refer to the core part of the electronic device, and its specific form is usually related to the type of the electronic device. For example, when the electronic device is a notebook computer, the device main body can include a shell and a display screen, electronic elements, a circuit board and a processor arranged in the shell. The key can be arranged on the shell and electrically connected to the processor in the shell. The user can interact with the electronic device through the key.
[0040] Reference Figure 1 and Figure 2The application also provides a key. The key can include a base 1, a keycap 2, a scissors leg assembly 3, and a guide structure 4. The keycap 2 is arranged above the base 1 in a liftable manner. The scissors leg assembly 3 can include a first support 31 and a second support 32. The first support 31 and the second support 32 are rotatably connected through a rotating part. The scissors leg assembly 3 is arranged between the base 1 and the keycap 2, so that the first support 31 and the second support 32 can be driven to rotate relatively during the lifting of the keycap 2 relative to the base 1. The guide structure 4 is arranged on the base 1. At least one of the first support 31 and the second support 32 has a matching part 311. The guide structure 4 can guide the matching part 311 in the lifting direction of the keycap 2 to guide the relative rotation of the first support 31 and the second support 32.
[0041] In the application, the base 1 is an important component of the key. The base 1 is usually located at the bottom of the key to support and fix the key. The material of the base 1 can be plastic or metal, which is not limited in the application.
[0042] In the application, the keycap 2 can refer to the top covering part of the key. The keycap 2 can be made of plastic or other materials, and the key can be marked with the function, number or other letters of the corresponding key.
[0043] In the application, the scissors leg assembly 3 can balance the pressing force of the keycap 2. The scissors leg assembly 3 can include the first support 31 and the second support 32 rotatably connected. During the pressing of the keycap 2 by external force, the first support 31 and the second support 32 can be driven to rotate relatively, so that the keycap 2 can be dispersed to the surrounding of the pressing position under the external force, thereby balancing the pressing force of the keycap 2.
[0044] In the application, the guide structure 4 can guide the matching part 311 on the scissors leg assembly. Therefore, the guide structure 4 can have various structural forms, such as a plate structure, a block structure, or a rod structure, which is not limited in the application.
[0045] In the application, the matching part 311 can be arranged only on the first support 31, only on the second support 32, or on both the first support 31 and the second support 32, which is not limited in the application.
[0046] In the application, during the relative rotation of the first support 31 and the second support 32, the guide structure 4 can guide the matching part 311 in the lifting direction of the keycap 2 to guide the relative rotation of the first support 31 and the second support 32. Figure 7 and Figure 8The angle between the first support 31 and the second support 32 can be changed from alpha to beta, the guiding structure 4 can guide the matching part 311 in the lifting direction of the keycap 2, and the first support 31 and the second support 32 are guided to rotate relative to each other.
[0047] In the technical scheme provided in the embodiment of the application, the key can include a keycap 2, a scissors leg assembly 3 and a guiding structure 4. The keycap 2 can be used for being pressed by a user to trigger a corresponding key. The scissors leg assembly 3 can include a first support 31 and a second support 32. The first support 31 and the second support 32 can be rotatably connected through a rotating part. The scissors leg assembly 3 can be arranged between the base 1 and the keycap 2. In the process of the keycap 2 being pressed down, the first support 31 and the second support 32 can be driven by the keycap 2 to rotate relative to each other. The guiding structure 4 can be arranged on the base 1. At least one of the first support 31 and the second support 32 can have a matching part 311. In the process of the keycap 2 being pressed down, the guiding structure 4 guides the matching part 311 in the lifting direction of the keycap 2.
[0048] Compared with the scheme in the related art in which the first support 31 and the second support 32 only rotate relative to each other under the driving of the keycap 2, the key provided in the application includes the guiding structure 4, and at least one of the first support 31 and the second support 32 has the matching part 311. In this way, in the process of the keycap 2 being pressed down, the guiding structure 4 guides the matching part 311 in the lifting direction of the keycap 2, so as to constrain the movement direction of the first support 31 and the second support 32 in the lifting direction of the keycap 2. As a result, the force generated by pressing can be transmitted in the vertical direction as much as possible, the influence of the component force on the uneven force of the scissors leg assembly is reduced, the degree of the first support 31 and the second support 32 being prone to deflection when rotating relative to each other is reduced, and thus the pressing feeling of the key is improved.
[0049] In the embodiment of the application, the shape of the keycap 2 has multiple possibilities. For example, the shape of the keycap 2 can be square, that is, the size of the keycap 2 in the first direction is equal to the size of the keycap 2 in the second direction. Referring to Figure 1 In a possible embodiment of the application, the size of the keycap 2 in the first direction is greater than the size of the keycap 2 in the second direction. The first direction is perpendicular to the lifting direction of the keycap 2, and the second direction is perpendicular to the first direction and the lifting direction of the keycap 2, respectively. In this way, the pressing area of the keycap 2 in the first direction is greater than the pressing area of the keycap 2 in the second direction, so that the user can more easily position the keycap 2 in the first direction, and the accuracy and speed of the user pressing the key are improved.
[0050] In the embodiments of the present application, in the case that the size of the keycap 2 along the first direction is greater than the size of the keycap 2 along the second direction, the ratio between the size of the keycap 2 along the first direction and the size of the keycap 2 along the second direction can have multiple possibilities, for example, the ratio between the size of the keycap 2 along the first direction and the size of the keycap 2 along the second direction can be 2, 5 or 8, and the present application is not limited in this regard.
[0051] In the embodiments of the present application, the angle between the first support 31 and the second support 32 can have a first angle and a second angle, and the height of the keycap 2 corresponding to the first angle can be higher than the height of the keycap 2 corresponding to the second angle. In the case that the first support 31 and the second support 32 switch between the first angle and the second angle, the guide structure 4 can be used to guide the fitting part 311 in the lifting direction of the keycap 2. In this way, during the process of pressing the keycap 2, when the angle between the first support 31 and the second support 32 is the first angle, the guide structure 4 starts to guide the fitting part 311, and when the angle between the first support 31 and the second support 32 is the second angle, the guide structure 4 ends the guidance of the fitting part 311, so as to constrain the movement direction of the first support 31 and the second support 32 between the height of the keycap 2 corresponding to the first angle and the height of the keycap 2 corresponding to the second angle.
[0052] In the embodiments of the present application, the first support 31 and the second support 32 can rotate relative to the keycap 2 when the keycap 2 is pressed or rebounds, and thus the angle between the first support 31 and the second support 32 can have multiple possibilities in the lifting stroke of the keycap 2. In the lifting stroke of the keycap 2, the first angle can refer to the angle between the first support 31 and the second support 32 corresponding to the highest position of the keycap 2, and the second angle can refer to the angle between the first support 31 and the second support 32 corresponding to the lowest position of the keycap 2. In this way, the guide structure 4 can guide the matching part 311 throughout the lifting stroke of the keycap 2. Alternatively, the first angle can refer to the angle between the first support 31 and the second support 32 corresponding to the first height of the keycap 2, and the second angle can refer to the angle between the first support 31 and the second support 32 corresponding to the second height of the keycap 2, wherein the first height is lower than the highest position of the lifting stroke of the keycap 2, the second height is higher than the lowest position of the lifting stroke of the keycap 2, and the second height is lower than the first height. In this way, when the keycap 2 is pressed, the guide structure 4 starts to guide the matching part 311 when the keycap 2 descends to the first height, and the guide structure 4 ends the guidance of the matching part 311 when the keycap 2 descends to the second height, and the guide structure 4 only guides the matching part 311 in part of the stroke. Compared with the guide structure 4 guiding the matching part 311 throughout the lifting stroke of the keycap 2, the guide structure 4 only guiding the matching part 311 in part of the stroke can reduce the stress of the scissors leg assembly 3 in the non-critical stroke, and is beneficial to improve the structural stability of the scissors leg assembly; on the other hand, the guide structure 4 only guiding the matching part 311 in part of the stroke can adjust the pressing feeling of the key, for example, the guide structure 4 can only guide the matching part 311 in the initial stage of the descent of the keycap 2, so that the force generated by the pressing can be transmitted as much as possible along the vertical direction, avoiding the keycap 2 from being skewed or stuck, and after the initial stage of the descent of the keycap 2, the guide structure 4 ends the guidance of the matching part 311, so that the keycap 2 can touch the bottom faster, thereby providing a paragraph type pressing feeling for the user, and improving the operation experience of the user.
[0053] In the embodiments of the present application, the guide structure 4 has multiple possibilities in the guiding mode of the matching part 311, for example, the guide structure 4 can have a guide groove, and the matching part 311 can have a sliding block slidingly matched with the guide groove. Referring to Figure 2 、 Figure 3 and Figure 4In a possible embodiment of the present application, the guide structure 4 can have an inclined guide surface 411, and during the switching of the first support 31 and the second support 32 between the first angle and the second angle, the guide structure 4 can extend into the fitting portion 311 so that the guide surface 411 is in sliding fit with the inner wall of the fitting portion 311. Here, the guide structure 4 has the inclined guide surface 411, and during the switching of the first support 31 and the second support 32 between the first angle and the second angle, the movement track of the fitting portion 311 is an arc, and the guide structure 4 extending into the fitting portion 311 can make the guide surface 411 always in sliding fit with the inner wall of the fitting portion 311, which helps to improve the guiding effect of the guide structure 4 on the fitting portion 311. In addition, the guide surface 411 has a simple structure and is easy to process, which is helpful to reduce the production cost of the key.
[0054] In the embodiment of the present application, the fitting portion 311 can have various structural forms, for example, the fitting portion 311 can be a fitting hole, and the fitting portion 311 can also be an open slot, which is not limited in the embodiment of the present application.
[0055] With reference to Figure 2 , Figure 3 and Figure 4 , in the embodiment of the present application, the size of the fitting portion 311 in the first direction can be greater than the size of the fitting portion 311 in the second direction, and along the first direction, the guide structure 4 includes at least two spaced guide members 41, and the guide surface 411 is formed on the guide member 41. In this way, the guide member 41 is spaced at least two in the first direction, which can make the guide structure 4 guide the fitting portion 311 in multiple positions in the first direction, which is helpful to improve the guiding effect on the fitting portion 311.
[0056] With reference to Figure 5 , Figure 6 and Figure 9 , in the embodiment of the present application, the guide structure 4 can also have a positioning surface 412, the positioning surface 412 is connected with the guide surface 411, and when the first support 31 and the second support 32 are at the second angle, the fitting portion 311 can be in stop fit with the positioning surface 412 along the second direction. In this way, during the pressing of the key, the first support 31 and the second support 32 are at the second angle, the guide surface 411 ends the guiding of the fitting portion 311, and the positioning surface 412 can be connected with the guide surface 411 and the fitting portion 311 to stop fit along the second direction, so as to prevent the scissor leg assembly 3 from moving in the second direction, thereby improving the reliability of the key.
[0057] In the embodiment of the present application, the guide structure 4 can have various numbers, for example, the guide structure 4 can be provided with only one, or two or more than two can be spaced along the first direction, which is not limited in the embodiment of the present application.
[0058] With referenceFigure 2 、 Figure 3 and Figure 4 In a possible embodiment of the present application, at least two of the matching portions 311 are arranged at intervals along the first direction, the at least two matching portions 311 include a first matching portion 311a and a second matching portion 311b, and the first matching portion 311a and the second matching portion 311b are arranged at two ends of the scissor leg assembly 3, respectively. At least two of the guide structures 4 are arranged at intervals along the first direction, the at least two guide structures 4 include a first guide structure 4a and a second guide structure 4b, the first guide structure 4a is used for guiding the first matching portion 311a, and the second guide structure 4b is used for guiding the second matching portion 311b. Here, the first matching portion 311a and the second matching portion 311b are arranged at two ends of the scissor leg assembly 3, respectively, and the first guide structure 4a and the second guide structure 4b are used for guiding the first matching portion 311a and the second matching portion 311b, respectively. On the one hand, the first guide structure 4a and the second guide structure 4b can serve as force points, so that the pressure can be transmitted to each part of the scissor leg assembly 3 through the first guide structure 4a and the second guide structure 4b during the pressing of the keycap 2, thereby reducing the probability of deformation due to excessive local stress. On the other hand, the first guide structure 4a and the second guide structure 4b are arranged at two ends of the scissor leg assembly 3, respectively, so that more space can be reserved in the middle region of the scissor leg assembly, thereby providing more arrangement space for other components (such as a circuit board and a rebounding element). This avoids mutual extrusion between components and improves the overall space utilization.
[0059] With reference to Figure 11 and Figure 12 In the embodiment of the present application, the angle between the first support 31 and the second support 32 can also have a third angle, one of the first support 31 and the second support 32 can have a limiting portion 312, and the other of the first support 31 and the second support 32 can have a stop portion 321. When the first support 31 and the second support 32 are at the third angle, the limiting portion 312 and the stop portion 321 can be in stop cooperation in the relative rotation direction of the first support 31 and the second support 32. The first support 31 and the second support 32 are rotationally connected, so that the scissor leg assembly 3 itself has a certain activity. During the operation of installing the scissor leg assembly 3 to the base 1, the first support 31 and the second support 32 are prone to overturning, thereby affecting the installation efficiency. Here, one of the first support 31 and the second support 32 has the limiting portion 312, and the other has the stop portion 321, which can limit the rotation angle between the first support 31 and the second support 32, and can avoid the first support 31 and the second support 32 from overturning during the installation of the scissor leg assembly 3 to the base 1, thereby helping to improve the assembly efficiency of the key.
[0060] In the embodiments of the present application, the positions where the limiting portion 312 and the stop portion 321 are arranged have multiple possibilities. For example, the limiting portion 312 can be arranged on the first support 31, and the stop portion 321 can be arranged on the second support 32; or the limiting portion 312 can be arranged on the second support 32, and the stop portion 321 can be arranged on the first support 31. The embodiments of the present application do not limit this.
[0061] In the embodiments of the present application, the third angle has multiple possibilities. For example, the third angle can be greater than the first angle, or can be less than the first angle. The embodiments of the present application do not limit this. It should be noted that, in the process of designing the third angle, the limiting portion 312 and the stop portion 321 should be prevented from being stopped and matched in the pressing stroke of the keycap 2, so as to affect the normal pressing of the keycap 2.
[0062] In the embodiments of the present application, the connection mode of the scissors leg assembly 3 with the keycap 2 and the base 1 has multiple possibilities. For example, the opposite two ends of the first support 31 can be respectively connected with the keycap 2 and the base 1 in a sliding mode, the first end of the second support 32 can be connected with the keycap 2 in a rotating mode, and the second end of the second support 32 can be connected with the base 1 in a sliding mode along the second direction.
[0063] In another possible embodiment of the present application, along the lifting direction of the keycap 2, the first end of the first support 31 can be connected with the keycap 2 in a rotating mode, the second end of the first support 31 can be connected with the base 1 in a sliding mode along the second direction, the opposite two ends of the second support 32 can be respectively connected with the keycap 2 and the base 1 in a sliding mode, and the matching portion 311 can be arranged on the first support 31. In this way, during the pressing of the keycap 2, the first support 31 rotates relative to the second support 32 under the driving of the keycap 2, the first end of the first support 31 rotates relative to the keycap 2, the second end of the first support 31 slides relative to the base 1 along the second direction, and the opposite two ends of the second support 32 can respectively slide relative to the keycap 2 and the base 1 along the second direction, so that the scissors leg assembly 3 can adapt to the motion track of the keycap 2, and the stability of the scissors leg assembly 3 can be improved.
