Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electronic products, and particularly relates to a keyboard cover set and a terminal device. BACKGROUND

[0002] In recent years, with the pursuit of light weight and multi-function of mobile office terminals, a two-in-one computer formed by combining a tablet computer (hereinafter referred to as a tablet) with a keyboard cover has gradually been popularized and applied. The existing keyboard cover and tablet computer are mainly matched in the following ways:

[0003] Firstly, the keyboard and the leather cover are an integral article in the keyboard cover, and are divided into a leather reinforcing sheet and a keyboard. The reinforcing sheet is attracted to the tablet by a magnet or the like. When the keyboard cover supports the tablet, the bottom of the tablet is limited by the magnet or the like, the reinforcing sheet supports the tablet, and the reinforcing sheet, the tablet computer and the keyboard form a triangular structure.

[0004] Secondly, the keyboard cover has a keyboard slidably connected to the tablet and a rotating support for supporting the tablet. When the keyboard cover supports the tablet, the keyboard slides out relative to the tablet, and the rotating support supports the tablet.

[0005] However, in the first matching mode, part of the keyboard space of the keyboard cover needs to be matched with the bottom of the tablet, so that the touchpad cannot be integrated. In the second matching mode, the opening mode of the two-in-one computer is relatively complex and the steps are tedious. SUMMARY

[0006] The purpose of the embodiment of the application is to provide a keyboard cover set and a terminal device, which can integrate a touchpad on the keyboard and also simplify the opening steps of the terminal device with the above keyboard cover set.

[0058] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description is based on the accompanying drawings. Figures 1-12 The described embodiments are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0059] In the description 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0060] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0061] For ease of understanding, this application now provides explanations for the proper nouns or industry-standard terms that appear below:

[0062] A keyboard cover is an accessory used to support the keyboard and tablet in a 2-in-1 computer that combines a keyboard and a tablet.

[0063] Currently, 2-in-1 computers, including those with existing keyboard covers, mainly have the following problems: the tablet computer occupies part of the space on the keyboard, making it impossible to integrate the touchpad into the keyboard, and the way to open a 2-in-1 computer is relatively complicated and the operation steps are cumbersome.

[0064] Based on the above, this application provides a keyboard case 10 and a terminal device, which aims to integrate a touchpad on the keyboard 111 and simplify the opening steps of the terminal device with the keyboard case 10.

[0065] First aspect: such as Figures 1-3 As shown, this application embodiment provides a keyboard package 10, which includes a keyboard assembly 11 and a connection structure assembly 101. In this embodiment, the terminal 20 can refer to a mobile terminal device that does not have a physical keyboard 111, such as a tablet computer, mobile phone, e-reader, handheld learning machine, or electronic dictionary.

[0066] Specifically, the keyboard assembly 11 comprises a keyboard 111 and a bottom plate 112, the keyboard 111 is arranged on the bottom plate 112 and is in sliding connection with the bottom plate 112, and the driving assembly 12 is connected with one side of the keyboard 111. The keyboard 111 and the bottom plate 112 can be directly in sliding connection or in sliding connection by means of sliding members such as sliding rails 151.

[0067] Specifically, the connecting structure assembly 101 comprises the supporting assembly 13 and the driving assembly 12, the supporting assembly 13 is used for supporting the terminal 20 and is rotatable around one side of the keyboard 111, the supporting assembly 13 is connected with the driving assembly 12, and the specific connection manner of the above two is that the supporting assembly 13 and the driving assembly 12 are in rotational connection and at the same time the supporting assembly 13 and the driving assembly 12 also have a transmission connection relationship, the rotating force generated by the supporting assembly 13 can be transmitted to the driving assembly 12, and the driving assembly 12 is used for driving the bottom plate 112 to slide relative to the keyboard 111 under the driving of the above rotating force. In this way, when the user pulls the terminal 20 to make the terminal 20 present an inclined vertical state relative to the keyboard 111, the supporting assembly 13 will also rotate relative to the keyboard 111 along with the rotation of the terminal 20, and due to the transmission connection relationship between the supporting assembly 13 and the driving assembly 12, the supporting assembly 13 can transmit the driving force to the driving assembly 12 in the rotating process, so as to make the driving assembly 12 drive the relative sliding between the bottom plate 112 and the keyboard 111.

[0068] The driving assembly 12 can be specifically selected as an assembly formed by the combination of a gear transmission pair 124 and a roller 123, the gear pair transmits the rotating force generated by the rotation of the supporting assembly 13 to the roller 123 and makes the roller 123 rotate, the roller 123 abuts against the bottom plate 112 and can drive the bottom plate 112 to slide relative to the keyboard 111. The gear pair can also be replaced by a worm and gear structure, the worm is connected with the supporting assembly 13 and transmits the rotating force generated by the rotation of the supporting assembly 13 to the worm wheel, and the worm wheel transmits the rotating force to the roller 123.

[0069] Please refer to Figure 3The keyboard sleeve package 10 provided by the embodiment of the present application is further described as follows: in specific application, the terminal 20 such as a tablet computer or a mobile phone can be combined with the support assembly 13 of the connecting structure assembly 101 of the keyboard sleeve package 10, so as to form an integral device with the keyboard sleeve package 10. When the integral device needs to be activated, the user can pull the terminal 20 combined with the support assembly 13, so that the screen of the terminal 20 is turned to face the user, and the support assembly 13 combined with the terminal 20 is also turned relative to the keyboard 111. Thus, the turning force of the support assembly 13 is transmitted to the driving assembly 12, and the driving assembly 12 can drive the bottom plate 112 to slide relative to the keyboard 111. Since the bottom plate 112 is placed on a platform such as a table, the keyboard 111 can slide out relative to the bottom plate 112 at this time. Thus, the keyboard 111 is automatically slid out while the terminal 20 is pulled, which preferably simplifies the opening operation steps of the integral device, so that the user can open the integral device by only one action, and the user experience is improved. Meanwhile, the terminal 20 is matched with the support assembly 13, and the bottom of the terminal 20 is not in abutment with the keyboard 111 when the terminal 20 is pulled to the inclined state, so that the assembly space on the keyboard 111 is released, and other components such as a touchpad can be arranged on the keyboard 111, so that the keyboard 111 also has better multifunctionality. When the terminal 20 is pulled to the inclined state, the position of the bottom plate 112 relative to the supporting platform such as a table is unchanged, and the bottom plate 112 can also preferably stabilize the gravity center of the integral device.

[0070] In some other embodiments of the present application, as shown in Figures 4-6 The support assembly 13 includes a rotating frame 131, and the driving assembly 12 includes a fixed frame 121 and a driving piece 122. The fixed frame 121 is connected with one side of the keyboard 111, and the rotating frame 131 is rotationally connected with the fixed frame 121. The rotating frame 131 drives the driving piece 122, and the driving piece 122 drives the keyboard 111 to slide relative to the bottom plate 112.

[0071] Specifically, when the driving assembly 12 works, the fixed frame 121 is connected with one side of the keyboard 111, so that the connection between the driving assembly 12 and the keyboard 111 is first realized. Thus, when the driving piece 122 of the driving assembly 12 drives the bottom plate 112 to slide, the driving assembly 12 can provide a reaction force for the keyboard 111, so as to drive the keyboard 111 to slide out relative to the bottom plate 112. The rotating force applied by the rotating frame 131 can be transmitted to the driving piece 122 in a transmission manner, so that the driving piece 122 drives the keyboard 111 to slide relative to the bottom plate 112. Thus, the structure of the driving assembly 12 is simplified, and the overall structure of the keyboard sleeve package 10 is also simplified.

[0072] In some embodiments of the present application, as shown in Figure 5 The driving member 122 is a roller 123 which is at least partially exposed at the bottom of the fixing frame 121 and abuts against the bottom plate 112. The rotation of the rotating frame 131 drives the roller 123 to rotate. In this way, the rotation force applied by the rotating frame 131 is transmitted to the roller 123 to drive the roller 123 to rotate and drive the keyboard 111 to slide relative to the bottom plate 112. The damping force generated by the roller 123 is applied to the supporting assembly 13, so that the supporting assembly 13 can stably maintain the inclined or upright posture when the supporting assembly 13 is not subjected to force.

[0073] Specifically, the driving member 122 is set as the roller 123 which is exposed at the bottom of the fixing frame 121. In this way, the roller 123 can roll against the bottom plate 112 to apply a rolling friction force to the bottom plate 112. Since the bottom plate 112 is placed on a platform such as a table, the static friction force between the bottom plate 112 and the platform is usually greater than the rolling friction force applied by the roller 123 to the bottom plate 112. In this way, the driving assembly 12 can slide together with the keyboard 111 relative to the bottom plate 112 under the pushing of the reaction force applied by the bottom plate 112. The roller 123 abuts against the bottom plate 112 and applies a rolling friction force to the bottom plate 112, so that the relative sliding between the bottom plate 112 and the keyboard 111 can be simply and reliably achieved.

[0074] Optionally, the roller 123 has a silica gel surface or a rubber surface, so that the rolling friction force applied by the roller 123 to the bottom plate 112 can be enhanced, and the relative sliding between the bottom plate 112 and the keyboard 111 can be more efficient. The roller 123 can be a silica gel roller or a rubber roller as a whole, or a silica gel sleeve or a rubber sleeve can be sleeved on a plastic wheel body or a metal wheel body to form the silica gel surface or the rubber surface of the roller 123.

[0075] In some embodiments of the present application, the driving member 122 can further include a driving gear and a rack. The driving gear is at least partially exposed at the bottom of the fixing frame 121, and the rack is arranged on the bottom plate 112 and engaged with the driving gear. The rotation of the rotating frame 131 drives the driving gear to rotate. In this way, the driving gear can drive the keyboard 111 to slide relative to the bottom plate 112 through the transmission cooperation with the rack.

[0076] Specifically, as another form of the driving member 122, by replacing the roller 123 with a driving gear, and by making the driving gear mesh with a rack provided on the bottom plate 112, the driving gear can be driven to move along the length direction of the rack by the reaction force provided by the rack, thereby achieving the relative sliding between the bottom plate 112 and the keyboard 111. Since the driving gear and the rack have high transmission efficiency, the stable and efficient sliding of the keyboard 111 relative to the bottom plate 112 is achieved.

[0077] In some other embodiments of the present application, as shown in Figure 7 and Figure 8 the driving member 122 further comprises a gear transmission pair 124, the gear transmission pair 124 has an input shaft 125 and an output shaft 126 arranged oppositely, the input shaft 125 is connected with the rotating frame 131, and the output shaft 126 is connected with the roller 123 or the driving gear of the driving member 122.

[0078] Specifically, in operation, one end of the input shaft 125 of the gear transmission pair 124 is connected with the rotating frame 131, and the other end is connected with one of the gears of the gear transmission pair 124. The rotating frame 131 applies a rotating force to the input shaft 125, and the input shaft 125 transmits the rotating force to the gear transmission pair 124. The gear transmission pair 124 transmits the rotating force to the driving member 122 (the roller 123 or the driving gear) through the output shaft 126. The presence of the gear transmission pair 124 enables the rotating force from the supporting assembly 13 to be continuously transmitted to the driving member 122, thereby enabling the driving member 122 to continuously drive the keyboard 111 to stably slide relative to the bottom plate 112. Thus, the continuous and smooth adjustment of the angle of the terminal 20 is achieved. When the operator pulls the terminal 20 to open to any angle or closes the terminal 20 from any angle, on one hand, the operator can experience the continuous and smooth adjustment of the angle of the terminal 20, and on the other hand, the operator can also feel the damping feeling generated during the relative sliding of the keyboard 111 and the bottom plate 112 driven by the driving member 122. The damping feeling can be perceived by the operator during the pulling of the terminal 20, thereby improving the use quality of the keyboard cover 10.

[0079] In some other embodiments of the present application, as shown in Figure 8 the gear transmission pair 124 is a multi-stage gear pair. Specifically, by setting the gear transmission pair 124 as a multi-stage gear pair, the adjustment of the rotating torque applied by the rotating frame 131 is achieved, the rotating torque is amplified or reduced, and the size of the rotating torque transmitted to the driving member 122 is adjusted, thereby adjusting the sliding distance of the keyboard 111 relative to the bottom plate 112.

[0080] Optionally, the multi-stage gear pair can be composed of a plurality of gear shafts 127 which are sequentially transmissionally matched and arranged from the input end to the output end of the gear transmission pair 124, so that the assembly space in the length direction of the gear pair can be fully utilized, and the assembly space proportion in the circumferential direction of the gear pair can be avoided to be too large.

[0081] Exemplarily, the transmission assembly 122 further comprises a housing 128, the gear pair is arranged in the housing 128, and the housing 128 is arranged in the fixed frame 121, so that the presence of the housing 128 can achieve better protection of the gear transmission pair 124.

[0082] In some other embodiments of the present application, as shown in Figure 6 The support assembly 13 further comprises a supporting piece 132 for supporting the fixed terminal 20, and the supporting piece 132 is arranged on the rotating frame 131.

[0083] Specifically, the rotating frame 131 and the fixed frame 121 are rotationally connected, so that the supporting piece 132 arranged on the rotating frame 131 together with the terminal 20 such as a tablet computer can be rotated to an inclined state relative to the keyboard 111. The rotating frame 131 is rotationally connected with the input shaft 125 of the gear pair, so that the rotating frame 131 can transmit the rotating force generated when it rotates around a certain point of the fixed frame 121 to the gear pair. Exemplarily, the two ends of the rotating frame 131 can be rotationally connected with the fixed frame 121 through two rotating pieces 129 arranged in the fixed frame 121 and the fixed frame 121, respectively.

[0084] In some other embodiments of the present application, as shown in Figure 3 and Figure 6 The supporting piece 132 comprises a supporting plate 133, a supporting seat 134 and a first magnetic piece 135, the supporting seat 134 is arranged on the rotating frame 131, one side edge of the supporting plate 133 is connected with the supporting seat 134, and the first magnetic piece 135 is arranged in the supporting seat 134, so that the first magnetic piece 135 can adsorb the bottom of the terminal 20 to the supporting seat 134.

[0085] Specifically, the supporting seat 134 is arranged, so that the supporting seat 134 can achieve better support for the bottom of the terminal 20, the supporting plate 133 is arranged, so that the supporting plate 133 can achieve better support for the housing 128 of the terminal 20, and the first magnetic piece 135 is arranged at the bottom of the supporting seat 134, so that when the terminal 20 is in an inclined state, the first magnetic piece 135 can firmly adsorb the bottom of the terminal 20 to the supporting seat 134.

[0086] Optionally, the supporting seat 134 is provided with a groove 137 corresponding to the position of the bottom of the terminal 20, and the groove 137 is adapted to the configuration of the bottom of the terminal 20. The number of the first magnetic members 135 is not unique, and each of the first magnetic members 135 is located in the supporting seat 134 corresponding to the position of the groove 137. In this way, the contact and cooperation between the supporting seat 134 and the bottom of the terminal 20 is more stable.

[0087] In some other embodiments of the present application, as shown in Figure 3 The supporting member 132 further comprises a second magnetic member 136, and the second magnetic member 136 is arranged on the supporting plate 133. In this way, the second magnetic member 136 can attract the shell of the terminal 20 to the supporting plate 133.
