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. 2-4 , an embodiment of the present invention discloses a mobile terminal. The disclosed mobile terminal includes a casing 100 , a camera 200 , a first retractable member 300 , a second retractable member 500 , and a control device 600 .

The housing 100 has an inner cavity 120 . The camera 200 , the first telescopic element 300 , the second telescopic element 500 and the control device 600 are arranged in the inner cavity 120 . The frame 110 of the housing 100 is provided with a perforation, the perforation communicates with the inner cavity 120 , and the perforation can allow the camera 200 to pass through.

The first telescopic element 300 is an elastic telescopic element in a compressed state. The first retractable member 300 is connected to the camera head 200 and is used to apply an elastic force to the camera head 200 to make it protrude from the perforation. During the working process, the elastic force can drive the camera 200 to enter the through hole from the inner cavity 120, and then extend out of the casing 100 from the through hole, so as to prepare for the user's subsequent shooting.

The first telescopic element 300 may be a telescopic spring (for distinguishing the telescopic springs hereinafter, the telescopic springs here may be referred to as second telescopic springs), elastic rubber columns and other components with telescopic functions. Specifically, the housing 100 may be provided with a positioning member 400 , the positioning member 400 is used to be fixedly connected to one end (fixed end) of the first telescopic member 300 , and the other end of the second telescopic member 500 is connected to the camera 200 for moving The movement of the movable end relative to the fixed end realizes the expansion and contraction of the second telescopic member 500 . The positioning member 400 is a component in the housing 100 for positioning (eg, fixing) one end of the first telescopic member 300, and may be a positioning base specially configured for the first telescopic member 300 in the mobile terminal; Other components, in this case, in addition to performing their own functions, the component can also play a role of positioning one end of the first telescopic member 300 . Of course, the first telescopic member 300 can also be directly connected to the casing 100 to achieve the positioning of one end thereof.

The control device 600 may include a control body 610 , a first Hall device 620 and a first magnet 630 . The first magnet 630 is disposed on the camera head 200 and can move with the camera head 200 . The first Hall device 620 is used for sensing the magnetic flux of the first magnet 630 . The movement of the first magnet 630 causes the magnetic flux induced by the first Hall device 620 to change. The control body 610 controls the second retractable member 500 to shrink according to the change of the magnetic flux of the first magnet 630 sensed by the first Hall device 620 . The second telescopic member 500 can position the camera 200 in the inner cavity 120 in the extended state. The expansion and contraction of the second telescopic member 500 can play the role of avoidance and positioning.

The control main body 610 controls the second retractable member 500 to shrink, so that the positioning cooperation between the second retractable member 500 and the camera 200 is released, and the second retractable member 500 can avoid the camera 200 after being contracted, so that the camera 200 is blocked by the first retractable member 300 moves out of the housing 100 from the inner cavity 120 through the perforation. The control main body 610 can control the extension of the second retractable member 500, so that the second retractable member 500 can be positioned and matched with the camera 200, thereby positioning the camera 200 in the inner cavity 120 of the housing 100. At this time, the second retractable member 500 can play positioning. The positioning of the camera 200 in the inner cavity 120 means that the camera 200 will not protrude out of the casing 100 through the through hole under the positioning and cooperation of the elastic force of the first retractable member 300 . A telescopic element 300 is elastically connected, so the camera 200 can move within a set range by compressing the first telescopic element 300 in the inner cavity 120 .

The working process of the mobile terminal disclosed in the embodiment of the present invention is as follows:

The camera 200 is positioned in the inner cavity 120 of the housing 100 when the second retractable member 500 is in an extended state. Since the camera 200 is connected to the first retractable member 300 , pressing the camera 200 can further compress the first retractable member 300 . When the user uses the camera 200, the user presses the camera 200, so that the camera 200 drives the first magnet 630 to move together. The movement of the first magnet 630 will change the magnetic flux of the first magnet 630 sensed by the first Hall device 620 . In this case, the control body 610 changes the magnetic flux of the first magnet 630 sensed by the first Hall device 620 . Control the contraction of the second telescopic element 500 . The retraction of the second retractable member 500 will release its positioning with the camera 200 , so that the camera 200 can be driven by the elastic force of the first retractable member 300 into the through hole, and finally pushed out of the casing 100 from the through hole. When the camera 200 is outside the casing 100 , the photographing work can be performed.

When the user does not use the camera 200, the user can directly press the camera 200 to retract it into the inner cavity 120 of the housing 100, and finally the second retractable member 500 can be positioned in the inner cavity 120 when the second retractable member 500 is in the extended state, and finally The retraction of the camera 200 is realized.

It can be seen from the above working process that the mobile terminal disclosed in the embodiment of the present invention can ensure that the mobile terminal has the camera function, and the position of the camera 200 (moving from the inside of the casing 100 to the outside of the casing 100, moving from the outside of the casing 100 to the It can be converted into the housing 100) to realize its work, and the arrangement of the camera 200 will not occupy the area where the display screen is arranged on the mobile terminal, and will not limit the further increase of the screen ratio of the mobile terminal, thereby solving the problem of the camera in the prior art. The layout of the mobile terminal will affect the development of the mobile terminal in the direction of the large screen ratio.

In the embodiment of the present invention, the control main body 610 can control both the contraction of the second telescopic element 500 and the extension of the second telescopic element 500 . Of course, the control main body 610 can only control the contraction of the second telescopic element 500. When the second telescopic element 500 is an elastic telescopic element, the extension of the second telescopic element 500 is achieved by its own deformation recovery.

The first telescopic element 300 is an elastic telescopic element that exerts elastic force through its own elastic recovery, and the deformation recovery of the first telescopic element 300 can ensure the stability of driving the camera 200 . Meanwhile, the first telescopic element 300 can be realized by only using some simple components (eg, springs). This can reduce the structural complexity of the mobile terminal and at the same time reduce the manufacturing cost of the mobile terminal.

In the actual use process, when the first retractable member 300 pushes the camera 200 out of the casing 100 to take pictures, if the user accidentally drops the mobile terminal, the first retractable member 300 will fall when the camera 200 touches the ground. This can ensure that the camera head 200 elastically touches the ground, thereby avoiding damage caused by the camera head 200 touching the ground, and ultimately protecting the camera head 200 .

In the embodiment of the present invention, the second telescopic element 500 may adopt various structures, for example, the second telescopic element 500 may be a slider mechanism, a hydraulic telescopic element, a pneumatic telescopic element, and the like. Of course, the second telescopic member 500 may be a telescopic spring or a telescopic assembly including a telescopic spring. The embodiment of the present invention does not limit the specific structure of the second telescopic member 500 .

Referring to FIGS. 3-4 , in a specific implementation manner, the second telescopic member 500 may include an ejector pin 510 and a first retractable spring 520 . The ejector pin 510 is connected to the first retractable spring 520 and expands and contracts with the first retractable spring 520 And move. The thimble 510 is used for clamping and positioning with the camera 200 . Specifically, one end of the first telescopic spring 520 is a fixed end, and the other end is a moving end. During the expansion and contraction process, the movement of the movable end relative to the fixed end can realize the expansion and contraction of the first expansion and contraction spring 520 . The ejector pin 510 is connected with the moving end of the first telescopic spring 520, so as to follow the movement. The expansion and contraction of the first telescopic spring 520 will drive the ejector pin 510 to move, so that the ejector pin 510 avoids the camera 200 or realizes the positioning cooperation between the ejector pin 510 and the camera 200 . Specifically, the thimble 510 can be positioned by snapping with the camera 200 to realize the positioning of the camera 200 .

Based on the above structure, the control body 610 may include a controller 611 and a second magnet 612, and the second magnet 612 may be an electromagnet. The second magnet 612 is connected to one end of the first retractable spring 520 , and the ejector pin 510 is connected to the other end of the first retractable spring 520 . The controller 611 can control the current of the second magnet 612 to increase according to the change of the magnetic flux of the second magnet 612 sensed by the first Hall device 620 . The second magnet 612 is magnetically attracted to the ejector pin 510 . The thimble 510 is usually an iron piece.

In a specific working process, the controller 611 can increase the current of the second magnet 612. Since the second magnet 612 is an electromagnet, the increase of the current will increase the magnetic properties of the second magnet 612, thereby enabling a larger magnetic force to be applied. The suction force is used to adsorb the ejector pin 510 , and the ejection pin 510 will compress the first telescopic spring 520 when the ejector pin 510 is adsorbed, thereby causing the entire formed by the two to contract, that is, the contraction of the second retractable member 500 .

When the second retractable member 500 completes the avoidance of the camera 200 after being retracted, the second retractable member 500 does not need to be kept in the retracted state all the time. Of course, keeping the retracted state requires the second magnet 612 to maintain a large current all the time, which will also As a result, the power consumption of the mobile terminal increases. Based on this, the control body 610 may further include a second Hall device 613 . The second Hall device 613 is used for sensing the change of the magnetic flux of the first magnet 630 . Therefore, in the process of extending the camera 200 , the first magnet 630 also moves with the camera 200 , and the second Hall device 613 controls the second magnet 612 to power off according to the sensed change of the magnetic flux of the first magnet 630 . After the second magnet 612 is powered off, its adsorption force on the ejector pin 510 disappears, and the ejector pin 510 is pushed out again under the action of the deformation recovery of the first telescopic spring 520 . During this process, the first telescopic spring 520 will also be stretched accordingly, and finally the first telescopic element 300 will be stretched. Of course, at this time, the first telescopic member 300 is in an extended state and the camera 200 is not positioned.

Of course, when the camera 200 is retracted to the inner cavity 120 of the housing 100 , the controller 611 can control the second magnet 612 to energize again, and then increase the current through the second magnet 612 to realize the adsorption of the ejector pin 510 and the first expansion spring 520 retracts, and finally avoids the retraction of the camera 200.

It should be noted that, in the embodiment of the present invention, the magnetic flux of the first magnet 630 itself does not change during the moving process. Usually, the positions of the first Hall device 620 and the second Hall device 613 are determined, and when the first magnet 630 moves, the magnetic flux detected by the first Hall device 620 and the second Hall device 613 changes, and the control The controller 611 can perform corresponding control operations according to the change.

Since the first Hall device 620 and the second Hall device 613 sense the change of the magnetic flux, the triggering control operations are different. In order to facilitate the work of the two and improve the detection accuracy, in a preferred solution, the second Hall device 613 can be arranged between the through hole and the first Hall device 620, that is, the first Hall device 620 can be arranged on the first Hall device 620. The side of the two Hall devices 613 facing away from the through hole. Specifically, the first Hall device 620 is disposed on one side of the fixed end of the first telescopic member 300 . The second Hall device 613 may be disposed on the inner wall of the frame 110 .

In order to simplify the operation, in a preferred solution, the ejector pin 510 may have an inclined surface 511, and the inclined surface 511 is provided on the surface of the ejector pin 510 on the side facing the perforation. The inclined surface 511 can be slidably matched with the camera 200 , and the surface of the ejector pin 510 away from the inclined surface 511 can be positioned and matched with the camera 200 . During the operation of the ejector pin 510 of the above structure, the user directly presses the camera 200, the camera 200 slides relative to the inclined surface 511, and gradually pushes the ejector pin 510 during the sliding process, so that the ejector pin 510 presses the first telescopic spring 520 to contract, and then The avoidance of the camera 200 is realized. The camera head 200 needs to include a positioning structure (such as a positioning depression). After the sliding is completed, the ejector pin 510 will be reset under the elastic force of the first telescopic spring 520, so that the surface of the ejector pin 510 facing away from the inclined surface is positioned and matched with the positioning structure of the camera head 200. , and finally the camera 200 is retracted into the inner cavity 120 of the housing 100 . The ejector pin 510 with the above structure will undoubtedly make the folding operation of the camera head 200 simple and convenient, and at the same time, the structural complexity of the terminal can be simplified.

In order to achieve more stable positioning of the camera head 200 , in a preferred solution, there may be two second telescopic elements 500 , and the two second telescopic elements 500 are symmetrically arranged on both sides of the camera head 200 . In this case, the two second telescopic elements 500 can implement more balanced positioning of the camera 200 .

Generally, the camera 200 is small in size. In order to facilitate its installation and assembly with other components, the camera 200 can be installed on the camera bracket 700 , and the first retractable member 300 can be connected to the camera 200 through the camera bracket 700 . In a specific assembly process, the camera 200 may be installed on the camera bracket 700 first, and then the camera bracket 700 is used to achieve assembly with other components. In a preferred solution, the camera bracket 700 has an accommodating cavity, and the camera 200 is installed in the accommodating cavity of the camera bracket 700 . In this case, the camera bracket 700 can also protect the camera 200, which can reduce the probability of the camera 200 being damaged. In order to improve the stability of the movement of the camera bracket 700, in a preferred solution, a track may be provided in the housing 100, and the camera bracket 700 may be slidably matched with the track. The camera 200 is usually fixedly connected to the camera bracket 700 , and the two can be fixed directly by means of snap connection, or can be fixedly connected by an intermediate connector (eg, a threaded connector).

In the same way, the second telescopic member 500 can indirectly position the camera 200 through the matching between the second telescopic member 500 and the camera bracket 700 . Based on this, the camera bracket 700 may include a positioning portion 710 , and the positioning portion 710 is positioned and matched with the second telescopic member 500 . Specifically, the positioning portion 710 is usually the edge of the camera bracket 700 , as shown in FIGS. 3 and 4 . There are various ways for the positioning part 710 to achieve positioning and cooperation with the second telescopic element 500 . For example, the positioning part 710 is provided with a positioning hole, and one end (the end that can move) of the second telescopic element 500 can be inserted into the positioning hole. Positioning cooperation, in the positioning cooperation state, the camera bracket 700 will not move in the moving direction of the camera head 200 .

Of course, the positioning part 710 can also realize the positioning of the camera 200 by means of the first telescopic element 300 , the second telescopic element 500 will extend to a position where it interferes with the positioning part 710 , and the elastic force of the first telescopic element 300 will interfere with the camera bracket 700 On the second telescopic member 500 , the camera bracket 700 does not move in the moving direction of the camera 200 .

In order to improve the compactness of assembly and the dust and water resistance of the mobile terminal, in a preferred solution, after the camera 200 is folded in the inner cavity 120 of the casing 100, the positioning portion 710 can be attached to the inner wall of the casing 100, and the camera bracket 700 cooperates with perforation plug. Such a matching manner can prevent external water and dust from entering the interior of the mobile terminal through the perforation.
