Description

Technical Field

[0001] The present invention relates to the technical field of folding keyboards, and particularly to a fitting bottom plate for a folding keyboard and a frame for a folding keyboard.

Background Art

[0002] In recent years, folding keyboards have excellent portability because the occupied space after folding is small, especially in the longitudinal direction where the occupied space is halved after folding. They are widely accepted in the market, especially among users who need to carry the keyboard frequently, such as during business trips.

[0003] However, while conventional folding keyboards are excellent in portability, they are used as they are in the unfolded state during use, and there is no restraint on the unfolded keyboard. Therefore, the keyboard body located on both sides of the rotation axis is likely to swing during use, and furthermore, when a key near the rotation axis is strongly pressed, the keyboard may be accidentally folded.

[0004] In view of such circumstances, a fitting bottom plate for a folding keyboard and a frame for a folding keyboard have been proposed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The object of the present utility model is to provide a fitting bottom plate for a folding keyboard and a frame for a folding keyboard in order to solve the problems of the prior art where there is no restraint at the rotation connection part.

Means for Solving the Problems

[0006] In order to achieve the above object, the present utility model adopts the following technical means.

[0007] A bottom plate for a folding keyboard, including a contact plate, wherein the contact plate has fitting portions at both the left and right ends, and the fitting portions are used to fit with a frame for a folding keyboard, and when the fitting portions are fitted with the frame for a folding keyboard, the contact plate fits tightly to the bottom of the folding keyboard.

[0008] Preferably, the fitting portion is composed of a side bar and an edge bar. Two side bars are provided, each located at both ends of the edge bar. One end of the side bar, away from the edge bar, is provided to be rotatable horizontally within the contact plate.

[0009] Preferably, thickness-enhancing members are fixedly connected to both the left and right ends of the contact plate, and the side bars are provided so as to be rotatable horizontally within the thickness-enhancing members.

[0010] Preferably, the edge bar is provided with an upward projection.

[0021] Hereinafter, embodiments of the present utility model will be described in detail with reference to the accompanying drawings. Note that the embodiments described below are only some embodiments of the present utility model and do not limit all embodiments.

[0022] In the description of the present utility model, terms indicating orientation or positional relationship such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "side", "edge", "side", "end", etc. are based on the orientation or positional relationship shown in the drawings, and are for facilitating the understanding of the present utility model and simplifying the description, and do not mean that the device or member must have a specific orientation or be configured and operate in a specific orientation, nor do they limit the present utility model.

[0023] Example 1 As shown in FIGS. 1 to 6, the fitting bottom plate for a folding keyboard according to this embodiment includes an adhesive plate 1. The adhesive plate 1 is made of a soft material such as rubber or silicone, and fitting parts 2 are provided at both left and right ends of the adhesive plate 1. The fitting parts 2 are used for fitting with the frame of the folding keyboard.

[0024] When the mating portion 2 is mated with the frame for the folding keyboard, the contact plate 1 makes close contact with the bottom of the folding keyboard.

[0025] After unfolding the foldable keyboard, the contact plate 1 is placed at the bottom of the keyboard and pressed tightly against it. Furthermore, the fitting parts 2 on both the left and right sides are fitted with the frame for the foldable keyboard, forming an integrated structure that provides restraint and prevents the keyboard from wobbling during use. It also prevents the keyboard from folding outwards even if keys near the rotation axis are pressed hard.

[0026] As shown in Figure 2, the fitting portion 2 is composed of a side bar 201 and an edge bar 202, and the side bar 201 and the edge bar 202 are integrally molded.

[0027] Two side bars 201 are provided, each positioned at both ends of the edge bar 202 and bent. The angle between the side bars 201 and the edge bar 202 is in the range of 70 to 110°, and in this embodiment it is 90°, i.e., a right angle.

[0028] One end of the side bar 201, away from the edge bar 202, is provided within the contact plate 1 so as to be rotatable horizontally.

[0029] Thickening members 3 are fixedly connected to both the left and right ends of the contact plate 1, and the thickening members 3 are made of the same material as the contact plate 1 and are integrally molded.

[0030] The side bar 201 is provided so as to be rotatable horizontally within the thickness-enhancing member 3.

[0031] As shown in Figure 2, one end of the side bar 201 that is away from the edge bar 202 is bent horizontally and inserted horizontally into the thickening member 3.

[0032] Horizontal insertion holes are pre-formed at both ends of the aforementioned thickness-enhancing member 3.

[0033] When the mating portion 2 is mated with the frame for the foldable keyboard, the mating is performed by the side bar 201 and the edge bar 202.

[0034] The edge bar 202 is provided with an upper projection 301, which improves the operability when manually rotating the fitting portion 2.

[0035] The contact plate 1 is provided with notched grooves 302 at positions corresponding to both ends of the thickness-enhancing member 3.

[0036] As shown in Figure 2, the notched groove 302 is formed by cutting out both ends of the thickening member 3 to create a hollow shape, and is used to insert the side bar 201.

[0037] Extension parts 101 are provided on both the front and rear side walls of the contact plate 1, and the number of extension parts 101 provided on each of the front and rear side walls of the contact plate 1 is 2 to 4, with 2 on each side in this embodiment.

[0038] The extension part 101 is made of the same material as the contact plate 1 and is integrally molded.

[0039] When the contact plate 1 is in close contact with the bottom of the folding keyboard, the extension part 101 also comes into close contact with the front and rear side walls of the folding keyboard, improving stability.

[0040] An internal groove 4 is provided at the bottom of the contact plate 1.

[0041] When not in use, the contact plate 1 can be folded using the internal groove 4, thereby reducing the space it occupies.

[0042] Example 2 As shown in Figures 4 to 8, this embodiment provides a foldable keyboard frame corresponding to Embodiment 1.

[0043] The folding keyboard frame according to this embodiment is based on the folding keyboard fitting bottom plate described in Embodiment 1.

[0044] Furthermore, fitting grooves 6 are provided at both the left and right ends of the frame for the foldable keyboard, and the fitting portion 2 is fitted into the fitting grooves 6.

[0045] The frame for the foldable keyboard is the side edge portion 5 shown in the diagram.

[0046] The extension part 101 adheres closely to the front-to-back side edges 5 of the foldable keyboard.

[0047] The fitting groove 6 is provided on the left and right side edges 5 of the foldable keyboard. The fitting groove 6 is composed of a side groove 601 and an end groove 602.

[0048] Two side ditches 601 are provided, each located on either side of the end groove 602.

[0049] As shown in Figure 6, during fitting, the fitting portion 2 is rotated to fit the side bar 201 into the side groove 601 and the edge bar 202 into the end groove 602.

[0050] While preferred embodiments of this utility model have been described above, the scope of protection of this utility model is not limited to these. Any equivalent substitution or modification made by a person skilled in the art based on the technical concept of this utility model within the disclosed technical scope of this utility model shall be included in the scope of protection of this utility model.
