Detailed Description

In order to enable those skilled in the art to better understand the present application, the following description will make clear and complete descriptions of the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

Referring to fig. 1 to 3, a mobile terminal 1 provided in an embodiment of the present application includes a main body 10, a rotating shaft 20, a camera module 30, a torsion spring 40, and a buffer elastic member 50.

The main body 10 is a main body structure of the mobile terminal 1, and the main body 10 has a first surface 11 and a second surface 12 facing away from each other, and a connection end surface 13 connecting the first surface 11 and the second surface 12. The distance between the first surface 11 and the second surface 12 is the thickness of the main body 10, and the first surface 11 and the second surface 12 are rectangular or rounded rectangular. In this embodiment, the first surface 11 is a front surface of the main body 10, facing the user, and the second surface 12 is a back surface of the main body 10. The connection end face 13 is an end face located at the top end when the main body 10 is placed vertically. The first surface 11 is provided with a display screen which is the main display screen on the main body 10, and the second surface 12 is provided with no display screen or may be provided with a secondary display screen.

The first surface 11 does not have to reserve a hole site for installing the front camera, so that the display area of the display screen can be the same as the contour (i.e., the peripheral line) of the first surface 11, and no other non-display area occupies the display area within the contour range. For example, when the first surface 11 is a plane, the ratio of the front projection area of the display area to the area of the first surface 11 is high, and the ratio of the front projection area to the area of the first surface 11 has a high screen duty ratio (the screen duty ratio refers to the ratio of the screen area to the surface of the device where the screen area is located, the calculation method is that the screen duty ratio=the screen area/the surface area of the device where the screen area is located), and the ratio of the high screen duty ratio ranges from 85% to 100%, so that a large screen or a full screen is realized; for another example, when the first surface 11 is a curved surface, the contour line of the display area and the contour line of the first surface 11 overlap, thereby realizing a large screen or a full screen.

The main body 10 has a receiving space 15, the receiving space 15 is located at the junction of the second surface 12 and the connecting end surface 13, and penetrates through the connecting end surface 13 and the second surface 12, and is not connected with the first surface 11, and the receiving space 15 ensures that the integrity of the first surface 11 is not damaged, and is used for receiving the camera module 30. The accommodating space 15 may be formed at a middle point of the connecting end face 13, or may be formed at a position far to the left or right than the middle point, specifically, to facilitate the user to operate the camera module 30.

The rotating shaft 20 is located in the accommodating space 15, and in this embodiment, the rotating shaft 20 is located at the top of the main body 10 when it is vertically placed. The accommodating space 15 has a first inner surface 151 and a second inner surface 152 opposite to each other near the connecting end surface 13, and two ends of the rotating shaft 20 are fixedly connected to the first inner surface 151 and the second inner surface 152, respectively. The rotary shaft 20 is a cylindrical shaft body, and the axial direction is parallel to the extending direction of the connecting end face 13.

The camera module 30 is movably connected with the main body 10 through the rotating shaft 20 to be contained in the containing space 15 or turned over relative to the main body 10. The camera module 30 has a light incident surface 31 and a bonding surface 32 facing away from the light incident surface 31.

The light incident surface 31 is the side of the camera module 30 for capturing images. When the camera module 30 is accommodated in the accommodating space 15, the light incident surface 31 and the second surface 12 face the same direction as each other at the first photographing position, and the camera module is used as a rear camera. After the rotary shaft 20 is turned to the maximum angle, the light incident surface 31 and the first surface 11 face the same direction, and the second photographing position is used as a front camera. The camera module 30 has two lens modules arranged in the width direction (lateral direction) of the main body 10, and can achieve a high-quality photographing effect regardless of whether it is used in front or rear.

The attaching surface 32 is a back surface of the camera module 30, when the camera module 30 is located in the accommodating space 15, the attaching surface 32 is attached to the main body 10, and when the camera module 30 rotates to the front photographing position, the attaching surface 32 is exposed.

The torsion spring 40 has a spring body 400, a first torsion spring leg 41 extending from one end of the spring body 400, and a second torsion spring leg 42 extending from the other end. The spring body 400 has a spiral structure, which is hollow so as to be sleeved on the outer circumference of the rotating shaft 20. The first torsion spring leg 41 is located at the camera module 30, and the second torsion spring leg 42 is located at the body 10, thereby fixing the torsion spring 40 between the camera module 30 and the body 10. The torsion spring 40 has a maximum torsion angle of 180 ° to flip the camera module 30 180 ° from the rear photographing position to the front photographing position.

The first torsion spring leg 41 is located on the fitting surface 32, and the second torsion spring leg 42 is located in the accommodating space 15 and fixedly connected with the main body 10.

The attaching surface 32 is provided with a receiving groove 320 for receiving and fixing the first torsion spring leg 41, so that the first torsion spring leg 41 cannot deviate from the receiving groove 320 to affect the opening of the camera module 30. Accordingly, the second torsion spring leg 42 is also secured within the body 10.

The buffer elastic member 50 is connected between the torsion spring 40 and the main body 10 to provide a buffer for the rotation of the camera module 30, preventing the camera module 30 from being overturned by more than 180 ° by an excessive torsion force when being opened (overturned from the rear photographing mode to the front photographing mode). The buffer elastic member 50 may be a coil spring having a first end 51 and a second end 52, the first end 51 being fixed to the first torsion spring leg 41, and the second end 52 being fixed to any one of the fixed parts of the main body 10, such as the receiving space 15, or the axial center of the rotating shaft 20, etc. The buffer elastic member 50 may also be fixed between the second torsion spring leg 41 and the main body 10.

When the camera module 30 is opened to a certain angle, for example 170 °, the buffer elastic member 50 provides an elastic restoring force from the current position of the camera module 30 to the direction of the main body 10, that is, a resistance to the turning action, so as to reduce the turning speed of the camera module 30, and finally, the camera module 30 is gently turned to a 180 degree position to stop, thereby avoiding the impact and shaking of the camera module 30 and making the turning action more elegant.

The camera module 30 of the mobile terminal provided in this embodiment can obtain buffering at the position of the maximum angle when being turned over, and the impact force is reduced, so that shaking is avoided, the turning is more stable, and the turning action is more elegant.

The mobile terminal can be various handheld devices such as a tablet computer. As used herein, a "communication terminal" (or simply "terminal") includes, but is not limited to, a device configured to receive/transmit communication signals via a wireline connection, such as via a public-switched telephone network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network, and/or via a wireless interface (e.g., with respect to a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal). A communication terminal configured to communicate via a wireless interface may be referred to as a "wireless communication terminal," wireless terminal, "and/or" mobile terminal.
