[0002] The current projection devices usually adopt a relatively scattered button layout and a small button area. During use, users need to accurately align the buttons, which may cause problems such as inconvenient operation and accidental touches, which affects the user experience to a certain extent. Utility Model Content

[0003] The purpose of the utility model is to overcome the defects of the prior art and propose a full-button screen projection device. The full-button design makes it easier for users to press buttons without too much searching or precise alignment. Users can complete the screen projection operation faster, thereby saving time and improving work efficiency. This is especially important for users who may have poor eyesight or poor hand coordination.

[0004] The utility model provides a full-button screen projector, which includes a full-button upper shell 1, a middle frame 2 and a key board 4. The full-button upper shell 1 is connected to the middle frame 2, and the key board 4 is arranged in the middle frame 2, wherein pressing any position of the full-button upper shell 1 causes it to touch the key board 4.

[0005] Preferably, the keypad 4 is connected to a circuit board inside the projection device.

[0006] Preferably, silica gel 3 is arranged between the full-button upper shell 1 and the key panel 4 .

[0007] Preferably, the middle frame 2 is a metal middle frame.

[0008] Preferably, the full-button upper shell 1 and the middle frame 2 are connected by snap-fit ​​connection; wherein, a plurality of snap-fits 5 are arranged on the inner edge of the full-button upper shell 1, and a plurality of connectors are arranged in the middle frame, and the snap-fits and the connectors are used in conjunction with each other.

[0009] Compared with the prior art, the advantages of the present invention are:

[0010] The screen projector of the present invention has a large button area and is easy to operate, which reduces the possibility of accidental touches and improves the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solution of the utility model is described in detail below in conjunction with the embodiments and drawings.

[0017] The utility model provides a full-button screen projection device, such as Figure 1 As shown, the screen projector includes a full-button upper shell 1, a middle frame 2 and a keypad 4. The middle frame 2 is a metal middle frame, which ensures the stability and reliability between the full-button upper shell 1 and the middle frame 2. At the same time, the metal middle shell has good durability and heat dissipation, which can effectively protect the electronic components inside the screen projector, increase the service life of the screen projector, and effectively prevent wear. A silica gel 3 is set between the full-button upper shell 1 and the keypad 4, as shown in FIG. Figure 2 As shown, the silica gel 3 plays a buffering role between the full-button upper shell 1 and the key board 4, providing elastic support to ensure the safety of the device.

[0018] The full-button upper shell 1 of the utility model is connected to the middle frame 2 by snap-fit; Figure 3 As shown, several buckles 5 are arranged on the inner edge of the full-button upper shell 1, and several connectors are arranged in the middle frame 2. The buckles 5 are used in conjunction with the connectors to facilitate the maintenance of internal components and the replacement of the upper shell. The key panel 4 is arranged in the middle frame 2, wherein pressing any position of the full-button upper shell 1 causes it to touch the key panel 4. The key panel 4 is connected to the circuit board inside the projector. The circuit board is responsible for receiving the key panel signal and transmitting it to the main control chip of the projector. The circuit board and the key panel 4 are connected by conductive material to realize signal transmission. This transmission process is a conventional technical means in this field and does not involve improvement of the method. The design of the full-button operation area makes user operation more convenient and quick, and improves the user experience.

[0019] In actual application, users only need to press the full-button upper shell to realize the screen projection function. For example, by pressing the "Cast" button, the screen projector can project the content on the mobile device to display devices such as TVs or projectors. At the same time, users can also set other function buttons as needed, such as "volume adjustment" and "screen switching" to meet the needs of different usage scenarios.

[0020] Any content not described in detail in the present invention can be based on the conventional technical knowledge in the field.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not intended to limit it. Although the utility model is described in detail with reference to the embodiments, a person skilled in the art should understand that any modification or equivalent replacement of the technical solution of the utility model does not deviate from the spirit and scope of the technical solution of the utility model, and should be included in the scope of the claims of the utility model.
