Description

[Technical field]

[0001] The utility model relates to the technical field of wireless photographing equipment, and in particular to a handheld Bluetooth photographing screen with strong practicality and good user experience. [Background Technology]

[0002] With the continuous advancement of technology in recent years, the development of smartphones has also fully incorporated technologies such as artificial intelligence and 5G, making smartphones the most widely used patented products.

[0003] When people use smartphones to take photos, they generally need to take photos from a distance. Although there are selfie sticks to achieve this effect, the length of a selfie stick is generally less than 2 meters. When taking photos of multiple people, only the upper body can be photographed, and full-body photos cannot be taken as souvenirs. It is also not suitable for taking photos with many people.

[0004] Similarly, as the pixel of mobile phone cameras continues to improve, more and more people choose to use mobile phones to take photos, especially some travel enthusiasts. For the sake of portability, they choose to carry mobile phones instead of professional cameras when traveling. However, due to cost considerations, the front camera of a mobile phone is usually lower than the rear camera. In order to take clear photos, they usually choose to ask people nearby to help take photos. However, the results of the photos usually cannot meet the requirements of the person being photographed, and in many cases, there is no one around the photographer who can help take photos. When the delayed shooting function of the mobile phone is used to take photos, it is difficult for the photographer to take photos that satisfy the photographer because the photographer cannot see the lens;

[0005] Although a high-pixel front camera plus a selfie stick can solve the above problems, the cost of the mobile phone is high, which is a waste of resources for a communication tool like mobile phones that are updated quickly. In addition, due to the length of the selfie stick and the limitations of human vision, the photographer cannot be too far away from the mobile phone screen, which limits the area that the mobile phone camera can record. When taking a group photo with a large number of people, not all people can be shown in one photo.

[0006] In order to solve the above series of problems, the prior art has a design of setting a display screen on the back of the mobile phone, such as the utility model patent with application number CN201820008472.5 and patent name "A dual-screen mobile phone convenient for rear-mounted photography", which specifically discloses a dual-screen mobile phone convenient for rear-mounted photography, including a frame, a full screen is provided on the front side of the frame, a volume plus key is provided on the upper left end of the frame, a volume minus keyboard is provided on the lower side of the volume plus key, an index finger fingerprint sensing groove is provided on the lower side of the volume minus keyboard, a power button is provided on the right side of the frame, a thumb fingerprint sensing groove is provided on the lower side of the power button, a photo shortcut key is provided on the lower side of the thumb fingerprint sensing groove, a sound expansion hole is provided at the bottom of the frame, a charging port is provided on the right side of the sound expansion hole, and an earphone port is provided on the right side of the charging port. This device uses a large rear screen to solve the problems of video chatting and Selfie, and is also provided with a separate photo button and a side fingerprint unlocking function. Through the reasonable arrangement of various buttons and sensors, the problem of insufficient front area is solved, and the rear screen is used for video and photo, thereby realizing a full-screen structure on the front. This device has a reasonable structure, beautiful appearance, and is easy to promote.

[0007] However, the above design still has many problems, such as high cost, large limitations in use, lack of portability, and not conducive to sharing by multiple people. Based on this, further improvements and enhancements are needed on the basis of existing technologies. [Contents of the utility model]
