Detailed implementation manners

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only a part rather than all of the embodiments of the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present disclosure.

[0033] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure shall have the ordinary meanings understood by those of ordinary skill in the art to which the present disclosure pertains. The terms "first", "second" and similar words used in the present disclosure do not denote any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "a", "an" or "the" do not denote a quantity limitation, but mean that there is at least one. Words such as "including" or "comprising" mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. The terms "connected" or "coupled" do not limit to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms "upper", "lower", "left" and "right" are only used to indicate relative position relationships, and when the absolute position of the object being described changes, the relative position relationships may also change accordingly.

[0034] In related technologies, the lifting of the camera can only be achieved by manually pressing hard. During use, it is necessary to widely contact the upper part of the display and squeeze the middle frame or the screen of the display, resulting in deformation of the middle frame of the display or stains or even damage on the screen. During the process of being manually pressed hard, the camera module and the lifting mechanism of the display are easily damaged, thereby reducing its service life. Moreover, manually pressing the camera module requires a certain amount of effort, the operation experience is poor, the human-computer interaction is poor, and it is not convenient to use.

[0035] Reference Figure 1, To address the above problems, this embodiment provides a camera assembly that is applied inside a display device. The camera assembly includes a camera module 3, a moving structure 4, a control module 2, and a pressure sensor assembly 1;

[0036] The pressure sensor assembly 1 is disposed on the housing of the display device and is used to sense external knocks;

[0037] One end of the control module 2 is connected to the pressure sensor assembly 1 through a signal connection line, and the other end of the control module 2 is connected to the moving structure 4 through a signal connection line. The control module 2 is configured to receive the signal transmitted by the pressure sensor assembly 1 and send a control signal to the moving structure 4;

[0038] The camera module 3 is connected to the moving structure 4 through a connecting member 5. The moving structure 4 is configured to control the telescopic movement of the camera module 3 according to the control signal of the control module 2, so as to extend out of the housing of the display device or be received in the housing of the display device.

[0039] In the camera assembly of this embodiment, when in use, the user can control the lifting of the camera assembly by knocking on the sensing area of the pressure sensor assembly 1, without the need for large-area contact and strong pressing on the display and its camera position. Compared with the pressing pop-up camera, the camera assembly provided in this embodiment is more convenient to use, has strong human-computer interaction, has a longer service life than the mechanical lifting mechanism, and is less likely to cause artificial damage.

[0040] The lifting process of the camera assembly provided in this embodiment is as follows:

[0041] When the camera assembly needs to extend out of the display device for shooting, the moving process of the camera assembly is as follows:

[0042] The pressure sensor assembly 1 senses the user's knocking operation and transmits a sensing signal;

[0043] The control module 2 receives the sensing signal and issues a control signal according to the sensing signal;

[0044] The moving structure 4 receives the control signal and executes the instruction to control the camera assembly to extend out of the display device.

[0045] The process of the camera assembly retracting into the display device is as follows:

[0046] The pressure sensor assembly 1 senses the user's knocking operation and transmits a sensing signal;

[0047] The control module 2 receives the sensing signal and issues a control signal according to the sensing signal;

[0048] The moving structure 4 receives the control signal and executes an instruction to control the camera assembly to contract into the display device.

[0049] It should be noted that the number of taps can be preset, and the pressure sensor assembly 1 emits an induction signal only after sensing the preset number of taps to avoid misoperation.

[0050] For example, it can be set to tap twice, and the pressure sensor assembly 1 emits an induction signal when it senses two taps.

[0051] It should be noted that when the preset number of taps is multiple, the pressure sensor assembly 1 needs to sense consecutive preset taps before it will emit an induction signal.

[0052] It should be noted that the number of taps corresponding to the camera assembly extending out of the display device and the number of taps corresponding to the camera assembly contracting into the display device can be the same or different.

[0053] The specific structural form of the moving structure 4 can be various. In an exemplary embodiment, the moving structure 4 includes a driving motor 41 and a lead screw 42. The camera module 3 includes a camera bracket and a camera mounted on the camera bracket. The camera bracket is movably connected to the lead screw 42 through a connecting member. Driven by the driving motor 41, the lead screw 42 rotates to drive the camera assembly to perform telescopic movement.

[0054] In an exemplary embodiment, the control module 2 is integrally provided on the main board 6 of the display device.

[0055] Adopting the above solution can save space and facilitate wiring.

[0056] Reference Figures 2-9 , an embodiment of the present invention provides a display device, including the above camera assembly. A through hole is opened on the housing of the display device, and the camera module 3 can extend out of the housing or be received in the housing through the through hole.

[0057] Exemplarily, the through hole is provided at the top of the display device. The axial direction of the lead screw 42 is parallel to the direction from the bottom to the top of the display device. The camera module 3 can perform telescopic movement along the axial direction of the lead screw 42 to extend out of the housing or be received in the housing, but it is not limited thereto.

[0058] In an exemplary embodiment, the housing includes a middle frame 10 and a rear housing 20. A through hole is formed at the top of the middle frame 10. A limiting and fixing structure is provided on at least one of the middle frame side wall 101, the middle frame bottom wall 102 of the middle frame, the rear housing side wall 201 of the rear housing, and the rear housing bottom wall 202 of the rear housing to limit and fix the pressure sensor assembly 1.

[0059] The installation position of the pressure sensor assembly 1 of the camera assembly can be set according to actual needs, and the number of the pressure sensor assemblies 1 can also be set according to actual needs, which is not limited herein. For the convenience of user operation, in this embodiment, the pressure sensor assembly 1 is disposed on at least one of the side wall of the middle frame, the bottom wall, the side wall of the rear housing, and the bottom wall of the rear housing. Refer to Figures 2-4 In, the pressure sensor assembly 1 can be disposed on at least one of the first installation area 103, the second installation area 104, and the third installation area 203.

[0060] It should be noted that the sensitivity of the pressure sensor assembly 1 needs to be adjusted and set in advance to avoid misidentifying the pressure by the sensor due to the vibration of the whole machine or knocking on other positions, thus causing the unintentional lifting of the camera module 3.

[0061] It should be noted that when the display device is a liquid crystal TV or a desktop computer, placing the pressure sensor assembly 1 at the position of the middle frame bottom wall 102 or the rear housing bottom wall 202 is likely to cause accidental touch when lifting the display device. Therefore, the sensitivity of the pressure sensor assembly 1 disposed on the middle frame side wall 101 is lower than that of the pressure sensor assembly 1 disposed on the middle frame bottom wall 102 or the rear housing bottom wall 202 to avoid accidental touch.

[0062] Refer to Figure 6 In an exemplary embodiment, the pressure sensor assembly 1 includes a body 11 and a sensing portion 12 disposed on the body 11. The sensing portion 12 protrudes from the body 11.

[0063] A groove 105 is formed on the installation surface of at least one of the middle frame side wall 101 of the middle frame, the middle frame bottom wall 102 of the middle frame, the rear housing side wall 201 of the rear housing, and the rear housing bottom wall 202 of the rear housing. The shape of the groove 105 conforms to the shape of the sensing portion 12, and a part of the sensing portion 12 extends into the groove 105. Refer to Figure 5 、 Figure 7 and Figure 8 .

[0064] It should be noted that there is a gap between the sensing part 12 and the corresponding mounting surface to prevent misrecognition of pressure by the sensor due to vibration of the whole machine or knocking on other positions. The sensing part 12 protrudes from the main body 11, and a groove 105 is formed on the mounting surface of at least one of the side wall 101 of the middle frame, the bottom wall 102 of the middle part, the side wall 201 of the rear shell, and the bottom wall 202 of the rear shell. Part of the sensing part 12 extends into the groove 105. The groove 105 reduces the thickness of the knocking part, facilitating the deformation of the groove part to contact the sensing part 12 during the knocking operation, so as to be sensed by the sensing part 12.

[0065] Reference Figure 5 , in an exemplary embodiment, a protrusion 106 is provided at the bottom of the groove 105. There is a gap between the protrusion 106 and the sensing part 12, and when the groove 105 is knocked by an external force, the protrusion 106 can contact the sensing part 12, so that the sensing part 12 senses the external knocking.

[0066] The depth of the groove 105 can be set according to actual needs. The greater the depth of the groove 105, the thinner the thickness of the bottom of the groove 105. When a knocking operation is received, the deformation of the groove part is also greater, facilitating the sensing part 12 to sense the knocking operation and improving the sensitivity. The setting of the protrusion 106 facilitates the flexible setting of the pressure sensor assembly 1, which can not only ensure the deformation force of the groove part, but also ensure a gap between the pressure sensor assembly 1 and the groove 105 to avoid misrecognition.

[0067] It should be noted that the shape of the protrusion 106 can be set according to actual needs, but the groove 105 has a certain area. In order to ensure that the sensing part can be recognized as long as the user knocks at the groove, in some embodiments, the protrusion 106 is in a cross shape, but this is not a limitation.

[0068] In some embodiments, there is a gap between the protrusion 106 and the sensing part 12. When a knocking operation is received, the deformation of the groove makes the protrusion 106 contact the sensing part 12 to sense the knocking operation, thereby controlling the lifting of the camera module, improving the recognition accuracy, and reducing the misrecognition rate.

[0069] Reference Figures 5-9 , in an exemplary embodiment, the pressure sensor assembly 1 includes a first side and a second side arranged oppositely, and a third side located between the first side and the second side. The limiting and fixing structure includes:

[0070] A plurality of L-shaped limiting brackets 601, each of the L-shaped limiting brackets 601 includes a first bracket and a second bracket, the first bracket is located on the third side of the pressure sensor assembly 1, one end of the first bracket is fixedly arranged on the middle frame 10 or the rear shell 20, one end of the second bracket is connected to the first bracket and is suspended above the pressure sensor assembly 1;

[0071] Limit posts 602, at least one of the limit posts 602 is arranged on the first side and the second side of the pressure sensor assembly 1 respectively.

[0072] The rear shell 20 is located on the fourth side of the pressure sensor assembly 1, the fourth side is oppositely arranged to the third side, the rear shell 20, the L-shaped limiting bracket 601, and the limit posts 602 enclose to form an all-round limit and fixation for the pressure sensor assembly 1, ensuring that the pressure sensor assembly 1 will not be displaced due to the vibration of the whole machine.

[0073] In an exemplary embodiment, a plurality of first strip-shaped support frames 603 are arranged on the mounting surfaces of at least one of the middle frame side wall 101, the middle frame bottom wall 102, the rear shell side wall 201, and the rear shell bottom wall 202, and the first strip-shaped bracket 603 is connected to the first bracket of the corresponding L-shaped limiting bracket 601 to form a U-shaped structure.

[0074] The arrangement of the first strip-shaped support frame 603 can reduce the contact area between the pressure sensor assembly 1 and the mounting surface, avoid misidentification caused by the vibration of the whole machine, etc., and is beneficial to the heat dissipation of the pressure sensor assembly 1.

[0075] In an exemplary embodiment, the mounting surfaces of at least one of the middle frame side wall 101, the middle frame bottom wall 102, the rear shell side wall 201, and the rear shell bottom wall 202 further include a second strip-shaped support frame 604, and the extending direction of the second strip-shaped support frame 604 is perpendicular to the extending direction of the first strip-shaped support frame 603.

[0076] The first strip-shaped support frame 603 and the second strip-shaped support frame 604 interact with each other to improve the support stability of the pressure sensor assembly 1.

[0077] Exemplarily, a U-shaped limiting bracket 205 is arranged on the rear shell 20, refer to Figure 5 and Figure 7 , the U-shaped limiting bracket 205, the L-shaped limiting bracket 601, the first strip-shaped support frame 603, and the second strip-shaped support frame 604 cooperate with each other to improve the stability of the pressure sensor assembly 1.

[0078] An embodiment of the present utility model further provides a method for controlling the movement of a camera assembly, which is applied to the above-mentioned camera assembly and includes:

[0079] Sense an external knock and output a sensing signal;

[0080] Send a first control signal according to the sensing signal;

[0081] According to the first control signal, control the rotation of the lead screw 42 to drive the camera assembly to extend or retract into the display device.

[0082] To avoid misrecognition, the pressure sensor assembly outputs a sensing signal only when it senses multiple consecutive external knocks (for example, knocking twice continuously), so that the control module controls the camera assembly to perform corresponding movement operations.

[0083] The following points need to be explained:
