Description

Camera module and terminal equipment

technical field

The invention relates to a camera module and terminal equipment.

Background technique

With the increasing number of functions of terminal devices (such as mobile phones and tablet computers), more and more functional devices are configured on terminal devices, such as cameras, face recognition modules, ambient light-sensitive modules, etc. Assembly presents great challenges. With the improvement of users' demand for the appearance of terminal equipment, users are increasingly favoring terminal equipment with a large screen ratio. On the premise that the size of the whole machine is determined, the larger and larger screen ratio will lead to the board that was previously set on the terminal device. There is not enough installation space for functional devices on the surface.

In order to increase the screen ratio of the terminal device, the current camera of the terminal device is a telescopic camera, and the telescopic camera is driven by a driving mechanism arranged in the casing of the terminal device, thereby realizing entering and exiting the casing. When the user needs to shoot, the driving mechanism is controlled to drive the telescopic camera to extend out of the casing, and then shoot. After the shooting is completed, the driving mechanism is controlled to drive the telescopic camera to retract into the casing, so as to achieve the purpose of hiding the camera. The terminal device with the above structure can avoid the camera from occupying its board space, thereby reducing the frame width of the casing, and the reduction of the frame width can increase the area of the display screen and finally increase the screen ratio of the terminal device. .

In the current terminal equipment, the driving mechanism includes a motor, which will lead to higher cost of the terminal equipment, and the use of motor drive requires a more complex transmission mechanism to realize the drive of the telescopic camera, which will undoubtedly lead to the terminal equipment. The structure is more complicated.

Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. 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 the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to FIGS. 1 to 4 , an embodiment of the present invention discloses a terminal device. The disclosed terminal device includes a casing 100 and a camera module. The camera module includes a camera 200 and a driving mechanism 300 .

The casing 100 has a frame 110 . The components forming the frame 110 are different for the casings 100 with different structures. For example, the case 100 may include a front case, a battery cover, and a middle frame disposed therebetween. The frame 110 may be formed on the middle frame. In this case, the frame 110 serves as a part of the middle frame. For another example, the case 100 includes a front cover and a battery cover, and the frame 110 can be formed on the front cover or on the battery cover. In this embodiment, the housing 100 has an inner cavity, thereby providing an installation space for the components of the terminal device. The frame 110 is provided with a through hole 111 , the through hole 111 communicates with the inner cavity, and the through hole 111 is used for the camera 200 to pass through.

The driving mechanism 300 is provided in the inner cavity of the housing 100 . The driving mechanism 300 is connected with the camera head 200 and can then drive the camera head 200 to move. Under the control of the driving mechanism 300 , the camera 200 can move, and then can enter and exit the through hole 111 , that is, the camera 200 can extend out of the casing 100 through the through hole 111 , and can also retract into the casing 100 through the through hole 111 . In this embodiment, the camera 200 includes a camera body 210 and a connecting portion 220 connected to the camera body 210 , the connecting portion 220 is provided with a guide rail, and the guide rail has a limit portion, the limit portion is used to be described later. The second end of the elastic limiting component 320 is limited and matched.

As described above, the driving mechanism 300 can control the movement of the camera 200 , thereby controlling the camera 200 to enter and exit the through hole 111 . In this embodiment, the driving mechanism 300 may include a first elastic member 310 , an elastic limiting component 320 and a telescopic driving component. The elastic limiting element 320 has an elastic restoring force, and the elastic restoring force can be generated by the action of the telescopic driving element. The telescopic drive assembly is connected to the first end of the elastic limiting assembly 320 to apply a force to the first end, and the second end of the elastic limiting assembly 320 is slidably matched with the guide rail. During the movement of the camera 200, the elastic limit The second end of the positioning assembly 320 can slide along the direction of the guide rail, and finally can slide to the position where the limiting portion is located.

The first elastic member 310 is disposed on the casing 100 , and is connected with the camera body 210 or the connecting portion 220 to apply elastic force to the camera 200 , and the camera 200 can pop out of the casing 100 under the action of the elastic force.

In this embodiment, the camera 200 can move relative to the casing 100, and has a retracted state and an ejected state. In the retracted state, the camera body 210 moves into the housing 100, and the second end of the elastic limiting component 320 slides into the limiting portion under the action of the aforementioned elastic restoring force, and cooperates with the limiting portion; In the state, the second end of the elastic limiting component 320 slides out from the limiting portion under the action of the telescopic driving component, and is further separated from the limiting portion, and the camera body 210 moves out of the housing 100 through the through hole 111 . Alternatively, in the retracted state, the camera body 210 is moved into the housing 100, and the second end of the elastic limiting component 320 slides into the limiting portion under the action of the aforementioned telescopic drive assembly, and cooperates with the limiting portion in a limited position; In the pop-up state, the second end of the elastic limiting component 320 slides out from the limiting portion under the action of the elastic restoring force, and the camera body 210 moves out of the housing 100 through the through hole 111 .

In an embodiment, the above-mentioned telescopic drive assembly can be a cylinder. In order to simplify the structure of the camera module and reduce the cost of the camera module, the telescopic drive assembly can be set as a magnetic assembly 330, which can be elastically limited to the position. The first end of the component 320 exerts a magnetic force, thereby controlling the matching relationship between the elastic limiting component 320 and the limiting portion.

Specifically, the magnetic force applied by the magnetic component 330 to the first end of the elastic limiting component 320 may be a magnetic attraction force or a magnetic repulsion force. When the magnetic force is the magnetic attraction force, in the retracted state, the camera body 210 moves into the housing 100 , and the second end of the elastic limiting component 320 slides into the limiting portion under the action of the aforementioned magnetic attraction, and is connected with the limiting portion. Limiting fit; in the pop-up state, the second end of the elastic limiting component 320 slides out from the limiting portion under the action of the elastic restoring force, and the camera body 210 moves out of the housing 100 through the through hole 111 . When the magnetic force is the magnetic repulsion force, in the retracted state, the camera body 210 moves into the housing 100 , and the second end of the elastic limiting member 320 slides into the limiting portion under the action of the aforementioned elastic restoring force, and is connected with the limiting portion. In the pop-up state, the second end of the elastic limiting component 320 slides out from the limiting portion under the action of magnetic repulsion, and the camera body 210 moves out of the housing 100 through the hole 111 . Relatively speaking, the solution of applying a magnetic attraction force is easier to implement, so in the embodiment of the present invention, it is preferable that the magnetic component 330 applies a magnetic attraction force to the first end of the elastic limiting component 320 . In addition, in the retracted state, the second end of the elastic limiting component 320 is slid into the limiting portion through the action of magnetic attraction, which can make the limiting more reliable. The elastic limiting component 320 and the magnetic component 330 can be arranged on the same side of the camera head 200, and the whole structure is more compact.

Taking the latter setting solution above as an example, in the specific use process, the user can press the camera 200 to retract the camera 200. During the retraction process of the camera 200, the camera 200 will move relative to the elastic limiting component 320, and then The second end of the elastic limit assembly 320 can be made to slide along the direction of the guide rail, and finally the second end of the elastic limit assembly 320 can be moved to the limit part. During this process, the camera 200 is pressed, which can overcome the first The elastic force of the elastic member 310 . After the camera head 200 is released, the camera head 200 tends to move back under the action of the elastic force. In this case, under the action of the magnetic attraction force exerted by the magnetic assembly 330, the limiting portion will limit the position with the second end of the elastic limiting member 320. In order to prevent the camera 200 from moving back, the camera 200 is kept in the inner cavity of the casing 100 , and finally the camera 200 is hidden.

When the user needs to shoot, the magnetic component 330 no longer applies the magnetic attraction force, so that the second end of the elastic limiting component 320 falls off the limiting portion under the action of the elastic restoring force and enters other positions of the guide track. Under the circumstance, the limit cooperation between the elastic limit component 320 and the limit part fails, the blocking effect on the camera 200 disappears or becomes smaller, and finally the camera 200 is pushed through the hole 111 to the housing 100 under the action of the elastic force. , and then complete the shooting preparation.

It can be seen from the above working process that in the terminal device disclosed in the embodiment of the present invention, the driving mechanism 300 can realize the telescopic movement of the camera 200 under the user's manual operation, and the user only needs to press the camera 200 during the whole operation process. Under the action of the elastic restoring force of the position assembly 320 and the telescopic drive assembly, the camera 200 can be kept in the casing 100 and ejected relative to the casing 100 . It can be seen that the telescopic movement of the camera 200 does not require a motor and a relatively complex transmission mechanism. Therefore, the terminal device disclosed in the embodiment of the present invention can solve the problems of high cost and complex structure of the current motor-driven camera telescopic.

In an optional embodiment, the elastic limit assembly 320 includes a slide rail 321, a slide rod 322, a limit block 323 and an action block 324. The slide rail 321 is disposed in the housing 100, and the slide rail 321 has a slide groove 321a. The sliding rod 322 is matched with the sliding slot 321 a , the limiting block 323 is provided on one end of the sliding rod 322 , and the action block 324 is provided on the other end of the sliding rod 322 . The action block 324 is the aforementioned first end, which is used to bear the magnetic force. The limiting block 323 is the aforementioned second end, which is used for limiting cooperation with the limiting portion. The structure of the elastic limiting assembly 320 is relatively simple, and the size of the acting block 324 and the limiting block 323 can be set relatively small, which neither affects the transmission of the acting force nor takes up too much space.

Further, the magnetic assembly 330 may include a bracket 331 and an electromagnet 332 disposed on the bracket 331 . The bracket 331 defines a connection hole 331 a, and the action block 324 is located in the connection hole 331 a. In addition, during the retraction and ejection process of the camera head 200, the action block 324 moves in the connection hole 331a. Through this structure, the position of the action block 324 can be limited. Even if the action block 324 is not affected by the magnetic attraction force, the entire elastic limiting component 320 will not move beyond the predetermined range due to the elastic restoring force, and the movement reliability of the entire structure is improved. high.

In order to generate the aforementioned elastic restoring force with a relatively simple structure, the elastic limiting component 320 further includes a second elastic member 325 for applying the elastic restoring force to the sliding rod 322 , and one end of the second elastic member 325 is connected to the housing 100 , which is the fixed end, and the other end is connected with the sliding rod 322 . When the magnetic component 330 exerts a magnetic attraction force, the sliding rod 322 moves and exerts a force on the second elastic member 325, so that the second elastic member 325 is deformed, thereby generating an elastic restoring force. When the magnetic attraction force disappears, the second elastic member 325 The elastic restoring force will react to the sliding rod 322 to make the sliding rod 322 move.

Optionally, both the first elastic member 310 and the second elastic member 325 can be configured as springs.

In the embodiment of the present invention, when the camera 200 and the second end of the elastic limiting component 320 move relatively, the second end of the elastic limiting component 320 can slide along the guide track. The guide rail plays a guiding role. The guide track may be a protrusion protruding on the surface of the camera head 200 , or may be a guide groove 230 . In order to improve the stability of sliding, in a preferred solution, the guide track is a guide groove 230 .

There are various structures of the guide groove 230 as long as the above-mentioned functions are met. In a specific embodiment, the guide groove 230 may include a limit groove section 231 and a guide groove section 232 , and the limit portion is formed in the limit groove section 231 . One end of the limit groove segment 231 is connected to one end of the guide groove segment 232. In the retracted state, the second end of the elastic limit assembly 320 is located at the other end of the limit groove segment 231. In the ejected state, the elastic limit assembly The second end of 320 is located at the other end of guide slot segment 232 . The function of the limiting groove section 231 is mainly to form a limiting portion, and the guiding groove section 232 is to improve the continuity of the movement of the second end in the guiding groove 230 .

In order to simplify the structure of the guide rail, the limiting groove segment 231 may be a linear groove segment extending along the acting direction of the elastic restoring force. When the second end moves under the action of the elastic restoring force, friction is unlikely to occur between the second end and the limiting groove segment 231 , so that the structural wear caused by the relative movement can be alleviated, so as to prolong the service life of the terminal equipment.

Similarly, in order to simplify the structure of the guide track, the guide groove section 232 can also be a straight groove section. The guide groove segment 232 extends from its connection with the limiting groove segment toward the direction close to the telescopic drive assembly. That is to say, the guide groove segment 232 is inclined relative to the limiting groove segment 231 in a direction close to the telescopic drive assembly. At this time, the guide groove section 232 has a certain inclination, and when the second end moves in the guide groove section 232, it is not easy to be stuck, thereby making the telescopic camera 200 more smoothly.

In order to provide guidance for the expansion and contraction of the camera 200, the terminal device provided in this embodiment of the present invention may further include a camera slide rail 400. One of the camera slide rail 400 and the connecting portion 220 is provided with a bar-shaped hole, and the other is provided with a connecting convex portion. The connection convex portion is matched with the strip hole, so that the camera slide rail 400 and the connection portion 220 can slide relative to each other. For example, the camera slide rail 400 is provided with a connection protrusion 410 , and the connection portion 220 is provided with a strip hole 221 . The camera slide rail 400 may be made of polyoxymethylene material.

The terminal device disclosed in the embodiment of the present invention may be an electronic device such as a smart phone, a tablet computer, an e-book reader, and a wearable device, and the embodiment of the present invention does not limit the specific type of the terminal device.

The above embodiments of the present invention mainly describe the differences between the various embodiments. As long as the different optimization features of the various embodiments are not contradictory, they can be combined to form better embodiments. No longer.

The above descriptions are merely embodiments of the present invention, and are not intended to limit the present invention. Various modifications and variations of the present invention are possible for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
