Description

Terminal Equipment

technical field

The present invention relates to the technical field of communication equipment, in particular to a terminal equipment.

Background technique

With the improvement of user demands, the screen-to-body ratio of terminal equipment is getting larger and larger, and a larger screen-to-body ratio can improve the appearance performance and display performance of the terminal equipment. Full-screen terminal devices have stunning visual impact and visual experience, and are favored by major manufacturers.

In order to achieve a full-screen design, some terminal devices adopt a sliding cover structure. The terminal device sets the display screen on the sliding cover, and hides various functional devices such as the front camera and the earpiece at the bottom of the top of the sliding cover and assembles them in the middle frame. in the top region of the . When the user needs the functional device to work, the sliding cover is manually slid to expose the functional device in the top area of the middle frame, thereby realizing related functions. When the functional device is not required to work, manually slide the sliding cover to realize the shielding of the functional device. This kind of terminal equipment can undoubtedly avoid the space occupied by functional devices on the board where the display screen is located, and achieve the purpose of full screen design.

The current slide fits between the slide cover and the middle frame, and the slide cover and the middle frame are connected by a torsion spring. During the sliding process, due to the action of the torsion spring, the slide cover can only stay at two limit positions, and the user experience is poor. . At the same time, the position between the sliding cover and the middle frame is maintained by a torsion spring. During the sliding process of the sliding cover, the sliding cover slides to different positions, and the elastic force produced by the torsion spring is different. When a force deviating from the sliding direction of the sliding cover is applied to the top, it is easy to cause the relative sliding between the sliding cover and the middle frame to be unsmooth.

SUMMARY OF THE INVENTION

The present invention discloses a terminal device to solve the problem of poor user experience caused by the slide cover of the current terminal device only being able to stay in two limit positions.

In order to solve the above problems, the present invention adopts the following technical solutions:

A terminal device comprising:

case;

A sliding cover, the sliding cover is slidably arranged on the housing, and a display screen is arranged on the sliding cover; wherein:

One of the housing and the sliding cover is provided with a rack, and the rack extends along the sliding direction of the sliding cover;

The other of the casing and the sliding cover is provided with a rotating member for rotation, and the rotating member is provided with gear teeth, and the gear teeth are engaged with the rack.

The technical scheme adopted in the present invention can achieve the following beneficial effects:

In the terminal device disclosed in the embodiment of the present invention, the sliding function of the sliding cover is realized by meshing the rack and the gear teeth of the rotating member between the sliding cover and the casing. Due to the meshing relationship between the rack and the rotating member, it is easy to form a relatively stable damping effect.

Detailed ways

In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The technical solutions disclosed by various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Referring to FIGS. 1-4 , an embodiment of the present invention discloses a terminal device, and the disclosed terminal device includes a housing, a sliding cover 100 , a rotating member 300 and a rack 400 .

The housing is the basic component of the terminal equipment, and the housing provides an installation basis for other components of the terminal equipment. In the embodiment of the present invention, the sliding cover 100 is slidably disposed on the housing, and the sliding cover 100 can slide relative to the housing. The sliding cover 100 is stacked on the casing, and the casing can be covered by sliding, and part of the casing can also be exposed through sliding. The sliding cover 100 is provided with a display screen.

As described in the background art, the surface of the casing facing the sliding cover 100 is usually provided with functional devices, such as a camera, a microphone, and the like. When the functional device needs to work, the user slides the sliding cover 100 , and the sliding cover 100 slides relative to the housing, so as to avoid blocking the area where the functional device is located. In this case, the functional device can work normally. When the functional device does not need to work, the user resets by sliding the sliding cover 100 , and the sliding cover 100 slides relative to the housing, thereby realizing the shielding of the functional device. The terminal device with the above-mentioned structure can hide some functional devices without affecting the normal operation of these functional devices, and finally can make the display screen set on the sliding cover 100 form a full screen, so as to increase the screen of the terminal device purpose of proportion.

In the embodiment of the present invention, one of the housing and the sliding cover 100 is provided with a rack 400, and the other is rotatably provided with a rotating member 300, the rack 400 extends along the sliding direction of the sliding cover 100, and the rotating member 300 is provided with The gear teeth are meshed with the rack 400 , so as to realize the relative movement cooperation between the housing and the sliding cover 100 . As shown in FIG. 1 , the rack 400 is disposed on the sliding cover 100 , and correspondingly, the rotating member 300 is disposed on the casing. Certainly, it is also possible that: the rack 400 is disposed on the housing, and correspondingly, the rotating member is disposed on the sliding cover 100 . In the embodiment of the present invention, the rotating member 300 may be a gear.

In the terminal device disclosed in the embodiment of the present invention, the sliding function of the sliding cover 100 is realized by engaging the rack 400 with the gear teeth of the rotating member between the sliding cover 100 and the casing. Due to the meshing relationship between the rack 400 and the rotating part, it is easy to form a relatively stable damping effect, so when the user slides the sliding cover 100, the sliding cover 100 can stay at any position, thereby improving the user's ease of use. experience.

At the same time, compared with the prior art that uses a torsion spring to connect the sliding cover to the housing, in the terminal device disclosed in the embodiment of the present invention, the sliding cover 100 will not be subjected to the elastic recovery force of the torsion spring during the sliding process. Therefore, it is also possible to avoid the problem that the sliding of the sliding cover is not smooth when the user's finger exerts a force deviating from the sliding direction of the sliding cover.

In order to better realize that the sliding cover 100 stays at any position, in a more preferred solution, at least one of the tooth surface of the rotating member 300 and the tooth surface of the rack 400 may be provided with a damping element.
