Description
Technical Field
[0001] The utility model relates to the technical field of tablet computer auxiliary equipment, in particular to a counterweight and a leather case keyboard. Background Art
[0002] A tablet computer, also called a portable computer, is a small, portable personal computer that uses a touch screen as the basic input device. Its touch screen allows users to use a stylus or digital pen to perform operations instead of a traditional keyboard or mouse. Users can input through built-in handwriting recognition, on-screen soft keyboard, voice recognition, or a real keyboard.
[0003] The leather case keyboard is a leather case with a USB keyboard or Bluetooth keyboard inside. It has its own keyboard and can protect the tablet computer. After the leather case keyboard is plugged into the USB port of the relevant device (or connected via Bluetooth pairing), you can use the external keyboard to type. The leather case keyboard includes a base plate and a cover plate with relatively adjustable angles. The base plate is used to fix the keyboard, and the cover plate is composed of two plates, on which a magnet that can attract the tablet computer is embedded or mounted with a protective shell that can fix the tablet computer. At the same time, the leather case keyboard can also serve as a folding stand when the tablet computer is in use.
[0004] In the prior art, in order to provide stable support for the tablet computer when in use, a counterweight is usually configured inside the keyboard to prevent shaking or tipping. The shape and size of the counterweight needs to be specifically designed in combination with the structural layout of the keyboard, which not only increases the complexity of the structure and the production cost, but also the built-in counterweight causes the overall thickness of the leather keyboard to be larger. As tablet computers become thinner and lighter, the leather keyboards that match them are also developing towards thinner and lighter. There is not enough space inside the keyboard to install the counterweight, so it is particularly important to design a new form of counterweight. Utility Model Content
[0005] In order to overcome the problems existing in the related technology, the utility model provides a counterweight piece and a leather case keyboard. The counterweight piece cancels the built-in counterweight block, and integrates the counterweight weight on the plate body to simplify the structure, thereby overcoming the disadvantage of the prior art that the counterweight block is separately set, resulting in a large overall thickness. When the counterweight piece is applied to equipment such as a leather case keyboard, there is no need to additionally configure a counterweight block separately. While ensuring the support stability, the overall thickness of the leather case keyboard can be reduced, making the leather case keyboard lighter and thinner.

[0038] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0039] The leather case keyboard is a leather case with a USB keyboard or Bluetooth keyboard inside. It has its own keyboard and can protect the tablet computer. After the leather case keyboard is plugged into the USB port of the relevant device (or connected via Bluetooth pairing), you can use the external keyboard to type. The leather case keyboard includes a base plate and a cover plate with relatively adjustable angles. The base plate is used to fix the keyboard, and the cover plate is composed of two plates, on which a magnet that can attract the tablet computer is embedded or mounted with a protective shell that can fix the tablet computer. At the same time, the leather case keyboard can also serve as a folding stand when the tablet computer is in use.
[0040] In the prior art, in order to provide stable support for the tablet computer when in use, a counterweight is usually configured inside the keyboard to prevent shaking or tipping. The shape and size of the counterweight needs to be specifically designed in combination with the structural layout of the keyboard, which not only increases the complexity of the structure and the production cost, but also the built-in counterweight causes the overall thickness of the leather keyboard to be larger. As tablet computers become thinner and lighter, the leather keyboards that match them are also developing towards thinner and lighter, and there is not enough space inside the keyboard to install the counterweight.
[0041] Example
[0042] In view of the above problems, the present embodiment provides a counterweight and a leather keyboard to simplify the structure, reduce the thickness of the product, and make the product lighter and thinner.
[0043] like Figure 1-4 As shown, a counterweight:
[0044] It includes a plate body 100, wherein the plate body 100 is composed of a first plate portion 110 and a second plate portion 120 connected in sequence;
[0045] The density of the first plate portion 110 is less than the density of the second plate portion 120;
[0046] The weight of the second plate portion 120 is greater than the weight of the first plate portion 110;
[0047] The present counterweight component eliminates the built-in counterweight block and integrates the counterweight weight on the plate body 100 to simplify the structure, thereby overcoming the drawback of the prior art that the counterweight block is separately provided, resulting in a large overall thickness.
[0048] In this embodiment, the first plate portion 110 is a plastic component, and the second plate portion 120 is a metal component.
[0049] In this embodiment, the first plate portion 110 and the second plate portion 120 are injection molded into one piece, thereby forming a plastic-metal composite structure, wherein the metal portion also has a counterweight function. At the same time, when the counterweight is applied to a specific product, such as as a keyboard base plate of a leather keyboard, the metal portion not only has a counterweight function, but also can increase the overall strength of the keyboard.
[0050] In this embodiment, the second plate portion 120 has an extended connection portion 121 , and the extended connection portion 121 is inserted into the first plate portion 110 . After connection, the second plate portion 120 and the connection end surface of the first plate portion 110 are in contact with each other.
[0051] In this embodiment, in order to improve the connection strength between the first plate portion 110 and the second plate portion 120, a plurality of through holes 122 are provided at intervals on the extending connection portion 121;
[0052] The first plate portion 110 has a notch 111 for accommodating the extended connecting portion 121 . A connecting protrusion 112 is disposed in the notch 111 . The connecting protrusion 112 is disposed in a one-to-one correspondence with the through hole 122 , and the connecting protrusion 112 passes through the corresponding through hole 122 .
[0053] Exemplarily, in order to improve the connection strength, the through hole 122 includes circular through holes and special-shaped through holes that are arranged alternately, and the connecting column is adapted to the shape of the corresponding through hole.
[0054] For example, the special-shaped through hole can be a strip hole, a cross hole, an arc hole or a polygonal hole, and its specific shape can be designed according to needs.
[0055] In this embodiment, a connection layer 113 extends from the bottom surface of the first plate portion 110 to the side where the second plate portion 120 is located;
[0056] The connecting layer 113 wraps the bottom surface of the second plate portion 120;
[0057] After the second plate portion 120 is manufactured, the second plate portion 120 is placed in an injection mold to inject the first plate portion 110, so that the first plate portion 110 and the second plate portion 120 form a plate body 100. The design of the connecting layer 113 can improve the connection strength between the first plate portion 110 and the second plate portion 120. At the same time, the plate body 100 adopts a plastic + metal design, which makes the overall strength of the plate body 100 higher.
[0058] This embodiment also provides a leather keyboard, which uses the above-mentioned counterweight.
[0059] Specifically, the leather keyboard comprises a bottom plate and a cover plate 200, the angles of which can be relatively adjusted.
[0060] The bottom plate is the above-mentioned counterweight;
[0061] The second plate portion 120 is located at the end side of the bottom plate away from the cover plate 200;
[0062] The bottom plate is provided with a keyboard 300;
[0063] When the counterweight is applied to equipment such as a leather case keyboard, there is no need to configure an additional counterweight block separately. While ensuring the support stability, the overall thickness of the leather case keyboard can be reduced, making the leather case keyboard lighter and thinner.
[0064] In this embodiment, the housing of the keyboard 300 is composed of a first housing portion and a second housing portion connected in sequence;
[0065] The weight of the second shell portion is greater than the weight of the first shell portion;
[0066] The second shell portion is located at the end side of the bottom plate away from the cover plate 200;
[0067] In this design, the shell of the keyboard 300 adopts the same dual-density solution as the counterweight, thereby further increasing the overall weight of the leather case keyboard without changing the structure of the keyboard 300. This design is conducive to the lightweight development of the leather case keyboard.
[0068] In this embodiment, the first shell portion is a plastic part, and the second shell portion is a metal part;
[0069] The first shell portion and the second shell portion are injection molded into one piece.
[0070] In this embodiment, the keyboard 300 and the bottom plate constitute a fixed part, which has the functions of data transmission and weight balance when in use, and the cover plate 200 is a movable part, which is used to adjust the angle of the tablet computer when in use;
[0071] The outer surfaces of the fixed part and the movable part are both wrapped with a skin layer.
