Description

Pop-up device and terminal equipment

Technical Field

The present disclosure relates to a pop-up device and a terminal apparatus having the same.

Background

With the popularization and development of smart phones, the role of the smart phones in daily life is more and more important. The mobile phone is not only a tool used by people for communication, but also a carrier for people to surf the internet, watch videos, watch electronic books and play games. With the increase of the application scenes of the mobile phone, the time for using the mobile phone is increased, and the requirements of people on the use experience of the mobile phone are higher and higher, wherein one important requirement is 'ultra-high screen occupation ratio'.

In order to improve the screen occupation ratio of the mobile phone, the upper frame and the lower frame of the mobile phone are reduced in the current mobile phone, and one of the problems which prevent the screen occupation ratio from being further improved is the arrangement problem of the front camera. The specially-shaped screen mobile phone with different forms such as the Liu Hai screen, the beauty tip and the water drop screen appears on the market successively, but in order to keep the function of the front camera, the opening and the slotting on the screen cannot be avoided, so that the improvement of the screen occupation ratio is hindered, and the visual experience of a user is also influenced. Therefore, the pop-up camera becomes one of the solutions for realizing the "ultra high screen ratio" at present. The pop-up camera is configured to hide the front camera inside the body, pop up from the inside of the body when the front camera needs to be used, and retract into the inside of the body after the front camera is used.

In the related art, the pop-up front camera includes automatic (power-driven) pop-up and manual pop-up. For the manual pop-up front camera, a structure similar to an SD card slot is currently adopted. The structure provides ejection force by virtue of the spring, utilizes the metal hook for limiting, and enables the metal hook to circularly move in the clip-shaped groove on the support of the front camera along with manual pressing of the front camera. Therefore, the front camera is switched among different states, and retraction limiting and ejection limiting of the front camera are achieved. The structure only depends on a thinner metal hook to realize limiting, and the metal hook can bear smaller elastic force, so that the locking state is not stable enough, and the front camera is easy to pop up due to inadvertent light touch.

Therefore, when the push block 25 is withdrawn from the third groove 32, the push block 25 can move the slide block 3 to the right by pushing the second inclined surface 322, and withdraw the slide block positioning portion 7 from the positioning groove 34.

Referring to fig. 1 to 9, the operation principle of the ejector will be described.

Referring to fig. 1 to 4 and 5, the ejecting apparatus is in a retracted state, the first spring 4 is compressed to make the ejecting unit 2 have a tendency to move upward for ejection, and the second spring 5 is compressed to make the slider 3 have a tendency to move rightward, so that the first and second catching

portions

33 and 253 cooperate to make the ejecting unit 2 unable to be ejected upward in the height direction Y by the elastic force of the first spring 4, thereby making the ejecting apparatus in the retracted state.

Referring to fig. 1 to 4 and 6, if ejection of the ejecting unit 2 is required, the ejecting unit 2 is pressed downward, and the ejecting unit 2 is moved downward by a small distance. In the process of downward movement of the push block 25, the first inclined surface 321 of the slide block 3 contacts with the third inclined surface 251 of the push block 25, so that the slide block 3 is pushed to move leftwards, the second spring 5 is further compressed, the positioning groove 34 moves to the upper part of the slide block positioning part 7, the compression of the third spring 6 is (partially) released, the slide block positioning part 7 is pushed into the positioning groove 34, and the slide block 3 is positioned. After the downward pressure is removed, the slider 3 does not move to the right under the elastic force of the second spring 5. It can be understood that, when the ejecting unit 2 is pressed downward, the slider 3 moves leftward by a distance greater than the amount of engagement of the first and second engaging

portions

33 and 253 in the width direction X in the retracted state.

Referring to fig. 1 to 4 and 7, after the downward pressure is removed, the ejecting unit 2 moves upward under the elastic force of the first spring 4, during the movement, the first clamping portion 33 and the second clamping portion 253 are staggered in the width direction X and cannot be clamped with each other, the second inclined surface 322 of the slider 3 contacts the fourth inclined surface 252 of the push block 25, and the push block 25 applies a rightward force to the slider 3, so that the slider positioning portion 7 is withdrawn from the positioning groove 34. The slider 3 can move rightward by the elastic force of the second spring 5. Preferably, during the upward movement of the ejecting unit 2, after the first catching portion 33 and the second catching portion 253 are staggered in the height direction Y (i.e., even if the slider 3 moves to the right, the first catching portion 33 and the second catching portion 253 do not catch), the push block 25 starts to push the second slope 322 of the slider 3.

Referring to fig. 1 to 4 and 8, the ejecting unit 2 moves upward until the first stopper portion 12 blocks the second stopper portion 24, so that the ejecting unit 2 cannot move upward, and the ejecting apparatus is in an ejecting state.

Referring to fig. 1 to 4 and 9, if retraction of the ejecting unit 2 is required, the ejecting unit 2 is pressed downward, the first spring 4 is compressed, and the ejecting unit 2 moves downward. The third slope 251 of the pushing block 25 contacts with the first engaging portion 33 (especially the slope of the first engaging portion 33), so that the pushing block 25 pushes the slider 3 to move leftward, the second spring 5 is compressed, the ejecting unit 2 is continuously pressed downward to the state shown in fig. 5, the first engaging portion 33 and the second engaging portion 253 are engaged, and the ejecting apparatus moves to the retracted state.

It should be understood that the left-right direction and/or the front-back direction (i.e., the paper surface side and the paper surface back side in fig. 1) in the present application may be reversed.

The invention also provides a terminal device which can be a mobile phone, a tablet computer and the like. Only take the mobile phone as an example, the width direction in the present application may correspond to the width direction or the up-down direction of the mobile phone, and the up-down direction in the present application may correspond to the up-down direction or the width direction of the mobile phone.
