Description

Technical Field

[0001] The present application relates to the technical field of keyboards, and more specifically, to an aluminum keyboard with an antenna added under a key. Background Art

[0002] With the continuous development of wireless communication technology, the requirements for wireless connection performance and stability of input devices such as keyboards are also increasing. Aluminum keyboards have been widely used in the market due to their advantages such as good durability, texture and heat dissipation performance. However, in some usage scenarios, such as environments with many interference sources or when longer transmission distances are required, the wireless signal reception of ordinary aluminum keyboards may be affected to a certain extent, resulting in problems such as unstable signals or transmission interruptions.

[0003] Currently, the metal aluminum shell keyboards on the market basically use external PCB boards or FPC antennas, etc. Due to the use of external antennas, many aluminum shell keyboards must have separate holes to accommodate the line access of the external antenna. In order to ensure the overall appearance and protection performance of the keyboard, additional nameplates are required to block the holes. This additional component not only increases the material cost, but also increases the overall production cost. From the perspective of structural design, the line layout of the external antenna requires special planning and avoidance inside the keyboard, which means that more effort needs to be spent on considering how to avoid these lines to ensure the rationality and stability of the internal structure of the keyboard.

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0029] Embodiment 1

[0030] Reference Figure 1-Figure 4 , an aluminum keyboard with an antenna added under a key, comprising a keyboard body 1, an antenna body 4 for sending and receiving signals is arranged at the bottom of at least one key 2 on the keyboard body 1, the antenna body 4 comprises a radiating portion 5, a connecting portion 6 and a supporting portion 7, the radiating portion 5 is located at one end of the antenna body 4, and the radiating portion 5 is fixedly connected to the keyboard body 1 through the connecting portion 6 and the supporting portion 7;

[0031] A hollow slot 3 for mounting an antenna body 4 is provided at the bottom of at least one key 2 on the keyboard body 1 , and the structure of the hollow slot 3 is adapted to the structure of the antenna body 4 .

[0032] Reference Figure 1-Figure 4 The support portion 7 is vertically arranged at one end of the connecting portion 6, and the lower end of the support portion 7 is fixedly connected to the bottom of the empty slot 3 through a welding point 8. The support portion 7 is also connected to the signal transceiver module on the keyboard body 1, and the radiation portion 5 has a spiral structure.

[0033] By adding an antenna body 4 under the key 2 of the keyboard body 1, compared with the traditional embedded antenna design, it can maximize the efficiency and performance of signal reception and transmission. At the same time, it is smaller than the previous aluminum shell keyboard antenna, occupies less space, and is easy to assemble the whole machine. It avoids the cost of opening windows in the aluminum shell and labor costs, and reduces the debugging cost. Structurally, compared with the line layout of the external antenna, there is no need for special planning and avoidance inside the keyboard body 1, which will not affect the rationality and stability of the internal structure of the keyboard body 1.

[0034] Working principle: the antenna body 4 is fixed by the welding point 8 in the empty groove 3 opened at the bottom of the key 2 of the keyboard body 1. The radiating part 5 of the antenna body 4 is spiral, which can better interact with external signals. When there is a wireless signal in the surrounding, the signal is first received and captured by the spiral radiating part 5, and then transmitted to the supporting part 7 through the connecting part 6, and finally the effective signal is transmitted to the keyboard body 1, so as to realize the wireless signal receiving function of the keyboard body 1. This method of utilizing the spiral radiating part 5 improves the efficiency and performance of signal reception. At the same time, since the antenna body 4 is small in size, occupies less space, and is installed under the key 2, it does not affect the normal layout and appearance of the keyboard body 1, and avoids complex operations such as opening windows in the aluminum shell during assembly, thereby saving costs, improving the convenience of assembly, and reducing debugging costs.

[0035] Embodiment 2

[0036] Reference Figure 5 Figure 7 The difference between this embodiment and the first embodiment is that a sound insulation strip 9 is provided on the top of the empty slot 3, and adhesive strips 11 are provided at both ends of one side of the sound insulation strip 9, and the two adhesive strips 11 are bonded to one side of the keyboard body 1, and a through opening 12 is opened inside the sound insulation strip 9, and a mounting piece 13 is provided inside the sound insulation strip 9, and the through opening 12 matches the size of the mounting piece 13, and an adapting hole 14 is opened inside the mounting piece 13, and the adapting hole 14 matches the antenna body 4, and strip-shaped slots 15 are opened at both ends of one side of the through opening 12, and insert strips 10 are provided at both ends of one side of the mounting piece 13 close to the sound insulation strip 9, and each insert strip 10 is respectively plugged into the corresponding strip-shaped slot 15, and each insert strip 10 is respectively interference fit with the corresponding strip slot 15.

[0037] The provision of the sound insulation strip 9 can effectively reduce the propagation of sound generated when the key 2 is pressed, reduce the keyboard tapping noise, provide a quieter use environment, and reduce interference with others. Through the cooperation of the mounting plate 13 and the through-hole 12, and the interference fit of the insert strip 10 and the strip slot 15, the sound insulation strip 9 can be firmly fixed on the top of the empty slot 3, providing certain protection for the antenna body 4, reducing damage to the antenna by external factors, and preventing dust, water vapor, etc. from entering the area where the antenna body 4 is located to affect the antenna performance. By matching the adapter hole 14 with the antenna body 4, the normal operation of the antenna body 4 can be ensured without affecting the signal reception of the antenna body 4.

[0038] Working principle: Through the mounting piece 13 inside the sound insulation strip 9, the insertion strip 10 and the strip slot 15 of the through opening 12 are interference fit, so that the sound insulation strip 9 can be firmly fixed on the top of the empty slot 3, and the adapter hole 14 on the mounting piece 13 matches the antenna body 4, while ensuring that the antenna body 4 receives signals normally, it provides physical protection for the antenna body 4, which can prevent foreign substances such as dust and water vapor from entering the area where the antenna body 4 is located, avoid adverse effects on the performance of the antenna body 4, and ensure the stable operation of the antenna body 4 and good signal reception effect. The sound insulation strip 9 mainly adds the functions of sound insulation and protection. When the user presses the button 2, the sound generated will be transmitted to the sound insulation strip 9 on the top of the empty slot 3. The sound insulation strip 9 absorbs and blocks the propagation of sound through its own material characteristics, thereby effectively reducing the noise generated when the button 2 is pressed, providing a quieter use environment.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
