Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display device. Background Technology

[0002] With the upgrading of consumer demand and the continuous development of technology, display devices such as televisions and monitors are gradually moving towards a thinner and more compact design.

[0003] Taking televisions as an example, current televisions are often used with camera modules, which are usually fixed to the back of the television so that the camera faces forward. However, as the overall size of camera modules becomes smaller and smaller, when used with thicker televisions, the viewing angle may be obstructed, resulting in a limited number of television models that the camera module can be compatible with. Utility Model Content

[0004] This application discloses a display device that enables the camera device to have a wider range of adjustment relative to the display device, thereby adapting to display devices of various thicknesses and sizes.

[0005] To achieve the above objectives, embodiments of this application disclose a display device, including:

[0006] The display device has a display surface and a back surface facing away from each other along a first direction, and an upper side surface connected between the display surface and the back surface;

[0007] A camera device, fixed to the display device, comprising:

[0008] Rotating bracket, the rotating bracket comprising:

[0009] Mounting component, which is fixed to the back side;

[0010] A first rotating component, one end of which is hinged to the mounting component;

[0011] The second rotating member has one end hinged to the other end of the first rotating member;

[0012] A camera module is hinged to the other end of the second rotating member. The camera module is configured to move relative to the mounting member under the rotation of the rotating bracket, so that the camera module can move on the upper side surface along the first direction and / or the second direction, and the shooting direction of the camera module is in the same direction as the display surface, the first direction is the thickness direction of the display device, and the second direction is the height direction of the display device.

[0013] The first rotating member and the second rotating member are hinged at both ends and have a clearance structure. The clearance structure is configured to avoid the first rotating member and the second rotating member when they rotate relative to each other, so that the angle of relative rotation between the second rotating member and the first rotating member is not less than 180°.

[0014] The rotating bracket includes a mounting component, a first rotating component, and a second rotating component that are hinged to each other. The camera module is hinged to the second rotating component, which means that the entire camera device has three hinge points. When the mounting component is fixed to the display device and the camera device is adjusted, there are two adjustable rotating components between the camera module and the mounting component. After the first rotating component rotates to a certain angle, the second rotating component can be further rotated, thereby controlling the height position of the camera module in the vertical direction and the front-back position in the first direction. At the same time, since the camera module can also rotate relative to the second rotating component, it is possible to achieve top-down and bottom-up views of the camera module.

[0015] As can be seen, this application, by setting multiple rotating components, enables the rotating components to present different folding methods, thereby realizing the lifting, extension, and tilting of the camera module. This allows for free adjustment of the camera module's extension range, making the camera module more adjustable relative to the display device, which is beneficial for adapting to display devices of various thicknesses and sizes. For example, when the display device is relatively thin, the extension of the camera module can be reduced by adjusting the first and second rotating components to fold backward, thus preventing the camera module from being knocked off while ensuring the viewing angle. Conversely, if the display device is too thick, changing the folding method of the first and second rotating components can increase the extension of the camera module, ensuring that the camera viewing angle is not obstructed.

[0016] Meanwhile, since both ends of the first and second rotating parts are hinged together, they are equipped with avoidance structures, which can avoid the first rotating part from rotating relative to the second rotating part. That is, the angle range of the second rotating part relative to the first rotating part can be expanded, so that the angle of the second rotating part relative to the first rotating part is not less than 180°, thereby further increasing the adjustment range of the camera module and making the camera device suitable for more scenarios.

[0017] In one optional implementation, in the mounting component, the first rotating component, the second rotating component, and the camera module, one of the two components that are hinged to each other is the first component, and the other is the second component;

[0018] The first component has a recessed portion at one end for hinged to the second component, forming a first part and a second part on both sides of the end of the first component. The first part has a first shaft hole, and the second part has a second shaft hole. The first shaft hole and the second shaft hole are opposite to each other along the axial direction of the first shaft hole and are both connected to the recessed portion.

[0019] The second component has a protrusion at one end for hinged to the first component, and a third shaft hole is provided on the protrusion. The protrusion is located in the recess, so that the first shaft hole, the second shaft hole and the third shaft hole are correspondingly arranged along the axial direction of the first shaft hole.

[0020] The rotating bracket further includes a rotating shaft assembly, which passes through the first shaft hole, the third shaft hole, and the second shaft hole to hinge the first component and the second component.

[0021] By employing a nested design of recessed and protruding portions for the two interconnected components, compared to the parallel hinge method in related technologies, the overall extension height of the camera device can be effectively reduced without altering the extension height of each component, thus significantly reducing the overall size of the camera device and making it suitable for ultra-thin display devices. Furthermore, the rotational insertion method of the first and second portions on both sides clamping the protrusion suppresses radial movement, making the rotational connection between adjacent components more reliable.

[0022] As an optional implementation, the first component is the second rotating component. When the second component is the first rotating component, both the first rotating component and the second rotating component have a first end and a second end that are disposed opposite to each other. The first end has the recessed portion, and the second end has the protruding portion.

[0023] The first end of the first rotating member is rotatably connected to the mounting member, the second end of the first rotating member is rotatably connected to the first end of the second rotating member, and the second end of the second rotating member is connected to the camera module.

[0024] The avoidance structure includes:

[0025] A first clearance portion is disposed at the first end and located at the recessed portion, and the first clearance portion is configured to clearance the protrusion.

[0026] The second avoidance part is disposed at the second end and located on both sides of the protrusion. The second avoidance part is configured to avoid the first part and the second part.

[0027] Since the first and second rotating components are rotatably connected by a protrusion extending into a recess, during rotation, the edge of the protrusion of the first rotating component will jam the edge of the recess of the second rotating component. The edges of the first rotating component on both sides of the protrusion will also jam the first and second parts of the second rotating component, causing the maximum angle of mutual rotation between the first and second rotating components to be limited by structural interference. Therefore, this application addresses this by placing a first clearance portion at the recess at the connection point of the first and second rotating components, and simultaneously placing a second clearance portion on both sides of the protrusion. This not only allows for mutual clearance and expands the rotation angle range, but also avoids affecting rotation by placing the two clearance portions on different components, rather than concentrating them at the same end of the same component. In other words, the layout of the first and second clearance portions is more rational with minimal structural modifications to the first and second rotating components.

[0028] For example, if the first clearance portion is located on the protrusion, the protrusion will also have to accommodate the opening of the third shaft hole for the shaft assembly to pass through, which will inevitably affect the rotary connection. Similarly, if the second clearance portion is located on the first and second portions, the first and second portions will also have to accommodate the opening of the first and second shaft holes for the shaft assembly to pass through, which will also affect the rotary connection.

[0029] As an optional implementation, the first rotating member and the second rotating member have a first surface and a second surface that are opposite to each other along a third direction, the second surface being the side closest to the opposite side;

[0030] The first rotating member and the second rotating member also have a first inclined surface located on both sides of the protrusion. The first inclined surface is connected between the first surface and the second surface so that the included angle between the first inclined surface and the second surface is an obtuse angle. The first inclined surface is configured to form the second clearance portion.

[0031] The first rotating member and the second rotating member also have a second inclined surface, which is inclined from the middle of the second surface toward the recess, so that the inclination direction of the second inclined surface is at an angle to the inclination direction of the first inclined surface, and the second inclined surface is configured to form the first clearance portion.

[0032] Wherein, the third direction refers to the thickness direction of the first rotating member and the second rotating member.

[0033] Since the first clearance portion is formed by a first inclined surface connecting the first surface and the second surface, and the angle between the first inclined surface and the second surface is an obtuse angle, that is, the first inclined surface is set towards the back of the display device; and since the second inclined surface is inclined from the middle of the second surface towards the recessed portion, so that the inclination direction of the second inclined surface is set at an angle to the inclination direction of the first inclined surface, the second inclined surface also faces the back of the display device. In other words, the design of the inclined surface allows the second rotating member and the first rotating member to have a larger range of rotation towards the display surface, thereby allowing the camera module to have a larger extension to the front side, making the viewing angle of the camera module less likely to be blocked, and being able to be used with display devices of more thicknesses, thus facilitating the adaptation to different usage scenarios of the camera device.

[0034] Furthermore, since both the first and second inclined surfaces are located on the back of the display device, the rotating bracket presents a relatively continuous and complete plane when viewed from the side where the first surface of the camera device is located, giving the camera device a good overall appearance.

[0035] As an optional implementation, the angle between the first inclined plane and the second inclined plane and the first surface is α, where α ≥ 45° and / or α < 90°.

[0036] If the inclination angles of the first and second inclined planes are too large, the steepness of the inclinations will reduce the effective load-bearing cross section of the material, thus weakening the structural strength of the rotating component. If the inclination angles of the first and second inclined planes are too small, the inclinations will be too gentle, and the protrusions and recesses may still collide at sharp edges during rotation, thus limiting the maximum rotation angle between the first and second rotating components.

[0037] Therefore, by reasonably setting the angles of the first and second inclined planes, it can be ensured that the structure remains stable even at the maximum rotation angle, thus avoiding deformation or breakage of the rotating parts due to excessive rotation.

[0038] As an optional implementation, the first portion has an inner peripheral surface for forming the first shaft hole, and a stop portion is provided on the inner peripheral surface. The stop portion is arranged axially around the first shaft hole to form a fourth shaft hole, and the stop portion has a third surface and a fourth surface that are opposite to each other along the axial direction of the first shaft hole.

[0039] The rotating shaft assembly includes:

[0040] The rotating shaft includes:

[0041] The head is located outside the second shaft hole;

[0042] The rod has one end connected to the head and the other end provided with a threaded hole. The rod passes through the second shaft hole, the third shaft hole and the first shaft hole in sequence, so that the first component and the second component can rotate relative to each other.

[0043] A threaded component, one end of which passes through the fourth shaft hole and is connected to the threaded hole;

[0044] The rod portion is spaced apart from the third surface along the axial direction of the first shaft hole to form a gap between them, and the other end of the threaded member abuts against the fourth surface. The gap is configured to provide deformation space for the stop portion so that the threaded member and the rotating shaft can achieve self-locking.

[0045] By maintaining a gap between the third surface of the rod and the stop, the stop provides sufficient deformation space when the threaded component is tightened. At this time, the stop deforms along the first direction towards the rod, generating a reaction force that subjects the threaded component to an outward pushing force similar to that of a spring washer, ensuring a self-locking effect after the threaded component and the shaft are locked. Therefore, replacing the traditional spring washer with a gap design in the threaded component achieves a self-locking effect between the threaded component and the shaft, making the threaded component more difficult to loosen, reducing the number of parts, and lowering costs.

[0046] Specifically, after the shaft rod is inserted into the shaft hole, the rod and the third surface of the stop are not in direct contact. When the threaded part is screwed into the threaded hole of the shaft rod, its end will press against the fourth surface of the stop, but it is not fully tightened at this time. As the threaded part continues to be tightened, the axial force of the threaded part pushes the stop to undergo elastic micro-deformation. Due to the existence of the gap, the stop undergoes elastic bending, generating a reverse force. This reverse force is transmitted to the threaded part through the fourth surface, forming a self-locking preload.

[0047] As an alternative implementation, the gap ranges from 0.05 mm to 0.3 mm.

[0048] If the gap between the shaft rod and the stop is too small, the third surfaces of the shaft rod and the stop will be in near contact, or even without gap. When the threaded part is tightened, the stop cannot generate sufficient rebound force through elastic deformation, resulting in reduced end-face friction, weakened self-locking effect, and potentially excessive contact between the shaft rod and the stop, causing rotational jamming. If the gap between the shaft rod and the stop is too large, the stop will bend excessively after the threaded part is tightened, and the deformation of the stop will exceed the elastic range, resulting in plastic deformation. The reaction force will drop sharply, and the self-locking effect will be lost.

[0049] Therefore, by limiting the gap range to a reasonable range of 0.05mm to 0.3mm, the preload is ensured to be moderate, so that the threaded part and the shaft maintain a good self-locking effect, and the threaded part is prevented from being too tight, which would cause rotational jamming, while also avoiding the situation of being too loose, which would cause shaking.

[0050] As an optional implementation, the mounting component is provided with a magnetic suction element inside, which is configured to attach to the display device so that the mounting component is fixed to the back surface;

[0051] The mounting component is provided with a rubber pad. When the mounting component is fixed to the back surface, the rubber pad is located between the back surface and the mounting component. The rubber pad is configured to maintain static friction between the mounting component and the back surface under the magnetic force of the magnetic attractor.

[0052] The mounting bracket is magnetically attached to the back of the display device, allowing the camera to be fixed without tools and making it easy for users to adjust the position of the camera.

[0053] Meanwhile, because the mounting piece is equipped with a rubber pad, after the mounting piece is fixed to the back, the rubber pad is located between the display device and the mounting piece. This means that, under the premise that the mounting piece can still be attached to the display device with the rubber pad, the adhesive force between the magnetic component and the display device can press the rubber pad more tightly between the mounting piece and the back of the display device, so that a large static friction force is generated between the mounting piece and the back. This static friction force not only has to withstand the weight of the entire camera device, but also prevents the camera device from falling off due to accidental impact.

[0054] In addition, the pad can adapt to the shape of the back of the display device that is not completely flat, and it can also adapt to the housing with various surface treatment processes (e.g., injection molding, painting, carbon fiber sheet, etc.).

[0055] As an optional implementation, the camera module includes:

[0056] A housing having a receiving cavity and a first mounting hole communicating with the receiving cavity;

[0057] A camera is disposed within the receiving cavity;

[0058] A circuit board is disposed in the receiving cavity and is electrically connected to the camera;

[0059] A connecting wire is provided, one end of which is used to connect to the display device, and the other end of which passes through the first mounting hole into the receiving cavity and is electrically connected to the circuit board.

[0060] In related technologies, the connecting wires of camera devices typically use a USB interface to plug into the camera module for data transmission. However, the USB plugs used in this method are expensive and prone to detachment during camera module adjustments, requiring re-plugging. Therefore, this application uses a connecting wire where one end connects to the display device, and the other end passes through a first mounting hole into the receiving cavity to electrically connect to the circuit board. In other words, the connecting wire eliminates the need for a USB plug, directly plugging into the circuit board inside the camera module. This not only saves costs but also avoids the possibility of the connecting wire becoming loose or even detaching from the camera due to camera module adjustments.

[0061] As an alternative implementation, the housing includes:

[0062] The housing has the receiving cavity and a first opening communicating with the receiving cavity. The housing is provided with a first notch located at the first opening. The housing also has a first inner wall for forming the first notch, and a first slot is provided on the first inner wall.

[0063] A cover plate is located at the first opening and connected to the housing. The cover plate has a second notch and a second inner wall for forming the second notch. A second slot is provided on the second inner wall. The second notch and the first notch are arranged opposite to each other to jointly enclose and form the first mounting hole. The first slot and the second slot are arranged opposite to each other.

[0064] The outer circumferential surface of the connecting wire is provided with a locking protrusion, which engages with the first locking groove and the second locking groove.

[0065] Because the connecting wire is directly inserted into the receiving cavity and connected to the circuit board, shear force is formed between the connecting wire and the rigid circuit board and at the hard-soft interface with the first mounting hole. This can easily lead to a low lifespan of the connecting wire during bending tests, causing fatigue fracture at the root of the connecting wire due to repeated bending.

[0066] To address this issue, this application provides opposing first and second notches on the inner walls of the first and second notches on the housing and cover, respectively, and a protrusion on the outer circumferential surface of the connecting wire. Firstly, after the connecting wire extends into the receiving cavity and connects to the circuit board, the protrusion is positioned within the two notches. The housing and cover then close together, causing the protrusion to be secured within the space formed by the first and second notches. This positioning structure of the first mounting hole makes the fixing of the connecting wire more reliable, reducing the radial bending degree and thus increasing the bending test life of the connecting wire. Furthermore, the protrusion design on the outer circumferential surface thickens the portion connecting the connecting wire to the mounting hole, further increasing the bending test life of the connecting wire. Moreover, the cooperation between the protrusion and the notch releases some of the bending stress from the connection point between the circuit board and the connecting wire to this cooperation point, mitigating the degree of bending of the connecting wire.

[0067] Furthermore, the positioning structure formed by the first and second slots makes the fixing of the connecting wires more reliable, prevents the axial movement of the connecting wires, and reduces the wear of the connecting wires.

[0068] Compared with the prior art, the beneficial effects of this application are:

[0069] The display device provided in this application employs a rotating bracket comprising a mounting component, a first rotating component, and a second rotating component that are hinged together. The camera module is hinged to the second rotating component, meaning the entire camera device has three hinge points. When the mounting component is fixed to the display device and the camera device is adjusted, there are two adjustable rotating components between the camera module and the mounting component. After the first rotating component rotates to a certain angle, the second rotating component can be further rotated, thereby controlling the height position of the camera module in the vertical direction and the front-back position in the first direction. In addition, the camera module can also rotate relative to the second rotating component to achieve top-down and bottom-up views of the camera module. Compared to the method of setting a single rotating component between the mounting component and the camera module in related technologies, this application allows the rotating component to present different folding methods, realizing the lifting, extension, and tilting of the camera module. The extension amount of the camera module can be freely adjusted, allowing the camera module to have a larger adjustable range relative to the display device, thus adapting to display devices of various thicknesses and sizes. For example, when the display device is thin, the extension of the camera module can be reduced by adjusting the first and second rotating parts to fold backward. This can prevent the camera from being knocked off due to excessive extension while ensuring the viewing angle. If the display device is too thick, the extension of the camera module can be increased by changing the folding method of the first and second rotating parts, ensuring that the viewing angle is not obstructed.

[0070] Meanwhile, since both ends of the first and second rotating parts are provided with avoidance structures, they avoid each other when the first and second rotating parts rotate relative to each other. This can expand the range of relative rotation angles between the second and first rotating parts, so that the relative rotation angle between the second and first rotating parts is not less than 180°. This further increases the adjustment range of the camera module, making the camera device suitable for more scenarios. Attached Figure Description

Unless otherwise stated, "a plurality of" means two or more.

[0091] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0092] See Figure 1 and Figure 2 , Figure 1 This application discloses a schematic diagram of the structure of a display device. Figure 2 The diagram illustrates a cross-sectional view of a display device disclosed in this application. The display device 1 includes a display unit 100, which includes, but is not limited to, electronic display products such as televisions, computer monitors, and liquid crystal display panels 100a, and can be widely used in places such as homes, offices, conference halls, exhibition halls, stations, hospitals, or shopping malls.

[0093] In some embodiments, the display device 1 includes a camera device 200, which is fixed to the display device 100. Taking a television as an example, the camera device 200 is used in conjunction with the television. For instance, the camera device 200 can enable video calls via a built-in camera 22 and microphone. When a user is in a game scene, the camera device 200 displays a real-time view of the participants. Alternatively, when a user is in an educational application, they can interact remotely with a teacher via audio and video in real time while learning the content on the screen, thus enriching the user experience.

[0094] In some embodiments, the display device 100 has a display surface 100a and a back surface 100b facing away from each other along a first direction X, and an upper side surface 100c connecting the display surface 100a and the back surface 100b. The display surface 100a is used to display image information and is typically oriented towards the user. It is understood that the first direction X is the thickness direction of the display device 100, i.e., the front-to-back direction of the display device 100. The upper side surface 100c is the top surface of the display device 100 in the height direction.

[0095] Please refer to the following: Figures 2 to 4 In some embodiments, the camera device 200 includes a rotating bracket 10, one end of which can be fixed to the back 100b of the display device 100.

[0096] In some embodiments, the camera device 200 includes a camera module 20, which is rotatably connected to the other end of the rotating bracket 10. This allows the camera device 200 to adjust the position of the camera module 20 via the rotating bracket 10, making the camera device 200 suitable for different application scenarios. Notably, to enable the camera module 20 to capture images, it is positioned above the upper side 100c.

[0097] In some embodiments, the rotating bracket 10 includes a mounting member 11 fixed to the back surface 100b. The mounting member 11 serves as a component for fixedly connecting the camera device 200 and the display device 100. Optionally, the mounting member 11 can be a plate-like structure or a base structure, and it can be rectangular or square to ensure a large connection area when fixed to the back surface 100b of the display device 100.

[0098] Combination Figure 2 In some embodiments, the mounting member 11 is provided with a magnetic member 111 inside, which is configured to attach to the display device 100 so that the mounting member 11 is fixed on the back surface 100b.

[0099] Optionally, the magnetic attractor 111 can be a neodymium iron boron permanent magnet, a ferrite magnet, or other magnets.

[0100] The mounting piece 11 is magnetically attached to the back 100b of the display device 100, allowing the camera device 200 to be fixed without tools, making it convenient for users to adjust the position of the camera device 200.

[0101] It's understandable that a thicker magnetic component 111 results in a stronger magnetic force, but the thickness cannot be excessive. Typically, the minimum distance between a wall-mounted TV and the wall is 5mm. To maximize the magnet area within the smallest possible structural space, taking a total weight of 100 grams as an example, the magnetic component 111 can be designed with a length and width of 20mm and 17mm respectively, and a thickness of 3mm. This size allows for fine-tuning of the camera device 200's height and ensures the stability of the magnetic component 111's area, preventing the camera device 200 from tilting to the left or right due to a shift in the center of gravity after being attracted.

[0102] Optionally, the back cover of the display device 100 in this embodiment can be made of metal, so that the mounting member 11 can be directly adsorbed onto the back cover. Alternatively, the back cover can be made of plastic. To achieve the adsorption of the mounting member 11, an iron plate can be provided on the inner side of the plastic back cover to achieve adsorption between the mounting member 11 and the iron plate. At the same time, a limiting groove is added to the back surface 100b of the back cover to enable more precise positioning of the mounting member 11 on the back cover.

[0103] In some embodiments, the mounting member 11 is provided with a rubber pad 112. When the mounting member 11 is fixed to the back surface 100b, the rubber pad 112 is located between the back surface 100b and the mounting member 11. The rubber pad 112 is configured to maintain static friction between the mounting member 11 and the back surface 100b under the magnetic force of the magnetic attractor 111.

[0104] Because the mounting part 11 is provided with a rubber pad 112, after the mounting part 11 is fixed to the back surface 100b, the rubber pad 112 is located between the display device 100 and the mounting part 11. This means that, under the premise that the mounting part 11 can still be attached to the display device 100 with the rubber pad 112, the rubber pad can be pressed more tightly between the mounting part 11 and the back surface 100b of the display device 100 under the action of the magnetic force between the magnetic part 111 and the display device 100. This results in a large static friction force between the mounting part 11 and the back surface 100b. This static friction force not only has to bear the overall weight of the camera device 200, but also prevents the camera device 200 from falling due to accidental collision.

[0105] In addition, the adhesive pad can also adapt to the non-completely flat shape of the back 100b of the display device 100, and can also adapt to the housing with various surface treatment processes (e.g., injection molding, painting, carbon fiber sheet, etc.).

[0106] Optionally, the pad can be a silicone pad, a rubber pad, or a frosted pad with good resilience, so that the surface of the pad has a high roughness, so that the static friction between the mounting part 11 and the back side 100b of the display device 100 is greater, and the anti-loosening effect is better.

[0107] In some embodiments, a limiting groove (not shown) is provided on the back surface 100b of the display device 100, and the mounting member 11 is located in the limiting groove, providing positioning and limiting functions for the mounting member 11. That is, by providing a limiting groove on the back surface 100b, on the one hand, it can provide an identification function for the installation of the camera device 200, guiding the camera device 200 to be installed in the correct position; on the other hand, it can provide a limiting function for the camera device 200, reducing the risk of the camera device 200 falling off.

[0108] In some embodiments, the back surface 100b of the display device 100 may be provided with reinforcing ribs (not shown) to enhance the structural strength of the housing of the display device 100 and reduce deformation. The mounting member 11 may be disposed above the reinforcing ribs, and the reinforcing ribs provide a certain support for the mounting member 11 of the camera device 200, making the camera device 200 less likely to fall off.

[0109] Combination Figure 3 and Figure 4 In some embodiments, the rotating bracket 10 includes a first rotating member 12, one end of which is hinged to the mounting member 11.

[0110] In some embodiments, the rotating bracket 10 includes a second rotating member 13, one end of which is hinged to the other end of the first rotating member 12.

[0111] Optionally, the first rotating member 12 and the second rotating member 13 can also be plate-shaped structures to maintain a generally consistent appearance with the mounting member 11, thus ensuring a consistent appearance of the rotating bracket 10. Alternatively, the first rotating member 12 and the second rotating member 13 can also be rod-shaped structures.

[0112] In some embodiments, the camera module 20 is hinged to the other end of the second rotating member 13. The camera module 20 is configured to move relative to the mounting member 11 under the rotation of the rotating bracket 10, so that the camera module 20 can move along the first direction X and / or the second direction Z on the upper side surface 100c. The shooting direction of the camera module 20 is in the same direction as the display surface 100a. The first direction X is the thickness direction of the display device 100, and the second direction Z is the height direction of the display device 100.

[0113] It is worth noting that the movement of the camera module 20 relative to the mounting member 11 may include: under the adjustment of the first rotating member 12 and the second rotating member 13, the camera module 20 may move along the first direction X (extend in the front-back direction), or move along the height direction of the display device 100 (rise and fall in the vertical direction), or move downward or upward relative to the second rotating member 13.

[0114] In some embodiments, both ends of the first rotating member 12 and the second rotating member 13 that are hinged to each other are provided with a clearance structure 101. The clearance structure 101 is configured to avoid the first rotating member 12 and the second rotating member 13 when they rotate relative to each other, so that the angle of relative rotation between the second rotating member 13 and the first rotating member 12 is not less than 180°.

[0115] The rotating bracket 10 includes a mounting member 11, a first rotating member 12, and a second rotating member 13 that are hinged to each other. The camera module 20 is hinged to the second rotating member 13, which means that the entire camera device 200 includes three hinge points. When the camera device 200 is adjusted by fixing the mounting member 11 to the display device 100, there are two adjustable rotating members between the camera module 20 and the mounting member 11. After the first rotating member 12 rotates to a certain angle, the second rotating member 13 can be further rotated, thereby controlling the height position of the camera module 20 in the vertical direction and the front and back position in the first direction X. At the same time, since the camera module 20 can also rotate relative to the second rotating member 13, it is possible to achieve top and bottom views of the camera module 20.

[0116] As can be seen, by setting multiple rotating parts, this application can enable the rotating parts to present different folding methods, thereby realizing the lifting, extension, and tilting of the camera module 20. This allows for free adjustment of the extension amount of the camera module 20, making the camera module 20 more adjustable relative to the display device 100, which is beneficial for adapting to display devices 100 of various thicknesses and sizes. For example, when the display device 100 is relatively thin, the extension amount of the camera module 20 can be reduced by adjusting the first rotating part 12 and the second rotating part 13 to fold backward, thus preventing the camera module 20 from being knocked off due to excessive extension while ensuring the viewing angle. Conversely, if the display device 100 is too thick, the extension amount of the camera module 20 can be increased by changing the folding method of the first rotating part 12 and the second rotating part 13, ensuring that the camera viewing angle is not obstructed.

[0117] Meanwhile, since both ends of the first rotating member 12 and the second rotating member 13 are provided with avoidance structures 101, they can avoid each other when the first rotating member 12 and the second rotating member 13 rotate relative to each other. That is, the angle range of the relative rotation of the second rotating member 13 and the first rotating member 12 can be expanded, so that the angle of the relative rotation of the second rotating member 13 and the first rotating member 12 is not less than 180°. This further makes the adjustment range of the camera module 20 larger, and thus makes the camera device 200 applicable to more scenarios.

[0118] It is worth noting that the angle of relative rotation between the second rotating member 13 and the first rotating member 12 is not less than 180° can mean that, with the first rotating member 12 and the second rotating member 13 located on the same straight line as a reference, the sum of the angle reached by the second rotating member 13 rotating clockwise relative to the first rotating member 12 to the limit position (cannot continue to rotate) and the angle reached by the second rotating member 13 rotating counterclockwise relative to the first rotating member 12 to the limit position (cannot continue to rotate) is not less than 180°. For example, the maximum rotation angle can reach 200°, 215°, etc.

[0119] Optionally, to ensure that the first rotating member 12 and the second rotating member 13 do not generate attractive interference during rotation, the magnetic suction member 111 may not be provided in the first rotating member 12 and the second rotating member 13. Of course, in actual scenarios where there are other requirements, such as when the display device 100 is thin and the camera device 200 does not need to protrude too much, the magnetic suction member 111 may be provided in the first rotating member 12 and / or the second rotating member 13, all of which are within the scope of protection of the technical solution.

[0120] It should be noted that the entire camera device 200 includes three hinge points: the hinge between the mounting member 11 and the first rotating member 12, the hinge between the first rotating member 12 and the second rotating member 13, and the hinge between the second rotating member 13 and the camera module 20. To achieve assembly consistency and improve assembly efficiency, these three hinge points can use the same hinge method, as detailed below:

[0121] In some embodiments, among the mounting member 11, the first rotating member 12, the second rotating member 13, and the camera module 20, one of the two hinged components is designated as the first component 14, and the other as the second component 15. That is, among the two hinged components, one is defined as the first component 14, and the other as the second component 15. Taking the hinged first rotating member 12 and the second rotating member 13 as an example.

[0122] Continue to publish references Figure 4 In some embodiments, the first component 14 is provided with a recess 141 at one end for hinged to the second component 15, so that a first part 142 and a second part 143 are formed on both sides of the end of the first component 14 along the first direction X. The first part 142 is provided with a first shaft hole 142a, and the second part 143 is provided with a second shaft hole 143a. The first shaft hole 142a and the second shaft hole 143a are opposite to each other along the axial direction of the first shaft hole 142a and are both connected to the recess 141.

[0123] In some embodiments, the second component 15 has a protrusion 151 at one end for hinged to the first component 14, and a third shaft hole 151a is provided on the protrusion 151. The protrusion 151 is located in the recess 141 so that the first shaft hole 142a, the second shaft hole 143a and the third shaft hole 151a are correspondingly arranged along the axial direction of the first shaft hole 142a.

[0124] In some embodiments, the rotating bracket 10 further includes a rotating shaft assembly 16, which passes through a first shaft hole 142a, a third shaft hole 151a and a second shaft hole 143a, so that the first component 14 and the second component 15 are hinged.

[0125] Taking the first component 14 as the first rotating component 12 and the second component 15 as the mounting component 11 as an example, the first rotating component 12 has a recessed portion 141 at one end for hinged with the mounting component 11, and the mounting component 11 has a protruding portion 151 at one end for hinged with the first rotating component 12. The protruding portion 151 of the mounting component 11 is located in the recessed portion 141 of the first rotating component 12, so that the first shaft hole 142a, the third shaft hole 151a and the second shaft hole 143a are correspondingly arranged so that the rotating shaft assembly 16 can pass through these shaft holes to realize the rotational connection between the mounting component 11 and the first rotating component 12.

[0126] By employing a nested design of recessed portion 141 and protruding portion 151 for the two interconnected components, compared to the parallel hinge method in related technologies, the overall extension height of the camera device 200 can be effectively reduced without changing the extension height of each component, thus significantly reducing the overall volume of the camera device 200 and making it suitable for ultra-thin display devices 1. Furthermore, the rotational insertion method of the protruding portion 151, using the first portion 142 and the second portion 143 on both sides, suppresses radial movement, making the rotational connection between adjacent components more reliable.

[0127] Of course, in other examples, the first component 14 can be the second rotating component 13 and the second component 15 can be the first rotating component 12. The second rotating component 13 is provided with a recessed portion 141 at the end where it is hinged to the first rotating component 12, and the first rotating component 12 is provided with a protruding portion 151 at the end where it is hinged to the second rotating component 13. The specific connection method can be referred to the above description, and will not be repeated here.

[0128] See Figure 5 In some embodiments, when the first component 14 is the second rotating component 13 and the second component 15 is the first rotating component 12, both the first rotating component 12 and the second rotating component 13 have a first end 10a and a second end 10b that are disposed opposite to each other. The first end 10a has a recessed portion 141 and the second end 10b has a protruding portion 151.

[0129] In some embodiments, the first end 10a of the first rotating member 12 is rotatably connected to the mounting member 11, the second end 10b of the first rotating member 12 is rotatably connected to the first end 10a of the second rotating member 13, and the second end 10b of the second rotating member 13 is connected to the camera module 20.

[0130] Since the first rotating member 12 and the second rotating member 13 are rotatably connected by the protrusion 151 extending into the recess 141, when rotating, the edge of the protrusion 151 of the first rotating member 12 will get stuck on the edge of the recess 141 of the second rotating member 13. The edges of the first rotating member 12 located on both sides of the protrusion 151 will get stuck on the first part 142 and the second part 143 of the second rotating member 13, so that the maximum angle of mutual rotation between the first rotating member 12 and the second rotating member 13 is limited by structural interference.

[0131] Based on this, in some embodiments, the avoidance structure 101 includes a first avoidance portion 101a, which is disposed at the first end 10a and located at the recess 141. The first avoidance portion 101a is configured to avoid the protrusion 151.

[0132] It is understood that when the first rotating member 12 and the second rotating member 13 rotate relative to each other, the first avoidance part 101a located at the recess 141 of the second rotating member 13 can guide and avoid collision between the second rotating member 13 and the protrusion 151 of the first rotating member 12.

[0133] In some embodiments, the avoidance structure 101 includes a second avoidance portion 101b, which is disposed at the second end 10b and located on both sides of the protrusion 151. The second avoidance portion 101b is configured to avoid the first portion 142 and the second portion 143.

[0134] It is understood that when the first rotating member 12 and the second rotating member 13 rotate relative to each other, the second avoidance portions 101b located on both sides of the protrusion 151 of the first rotating member 12 can guide and avoid collision between the first rotating member 12 and the first portion 142 and the second portion 143 of the second rotating member 13.

[0135] This application provides a first clearance portion 101a at the recessed portion 141 and a second clearance portion 101b on both sides of the protrusion 151 at the interconnected ends of the first rotating member 12 and the second rotating member 13. This not only allows for mutual clearance and expands the rotation angle range, but also avoids affecting rotation by placing the two clearance portions on different components rather than concentrating them at the same end of the same component. In other words, the layout of the first clearance portion 101a and the second clearance portion 101b is more rational with minimal structural modifications to the first rotating member 12 and the second rotating member 13.

[0136] For example, if the first clearance portion 101a is provided on the protrusion 151, the protrusion 151 will also have to bear the opening of the third shaft hole 151a for the shaft assembly 16 to pass through, which will inevitably affect the rotational connection. Similarly, if the second clearance portion 101b is provided on the first part 142 and the second part 143, the first part 142 and the second part 143 will also have to bear the opening of the first shaft hole 142a and the second shaft hole 143a for the shaft assembly 16 to pass through, which will also affect the rotational connection.

[0137] Combination Figures 5 to 7 In some embodiments, the first rotating member 12 and the second rotating member 13 have a first surface 12a and a second surface 12b that are opposite to each other along a third direction Y, with the second surface 12b being the side closest to the back surface 100b. Herein, the third direction Y is the thickness direction of the first rotating member 12 and the second rotating member 13.

[0138] It is understood that when the mounting member 11 is fixed to the back surface 100b, no matter what angle the first rotating member 12 and the second rotating member 13 rotate relative to the back surface 100b, the rotating member always has a surface that is close to and away from the back surface 100b in the thickness direction, and the second surface 12b is the side that is close to the back surface 100b.

[0139] In some embodiments, the first rotating member 12 and the second rotating member 13 further have first inclined surfaces 12c located on both sides of the protrusion 151. The first inclined surfaces 12c connect the first surface 12a and the second surface 12b such that the included angle between the first inclined surface 12c and the second surface 12b is an obtuse angle. The first inclined surface 12c is configured to form a second clearance portion 101b. In other words, the first inclined surface 12c is inclined in the direction from the first surface 12a to the second surface 12b toward the recess 141 of its own structure, that is, toward the first end 10a of itself.

[0140] Taking the first rotating member 12 as an example, the first inclined surface 12c of the first rotating member 12 is located at the second end 10b, and is inclined towards the recess 141 (or the first end 10a) of the first rotating member 12 in the direction from the first surface 12a to the second surface 12b. Taking the second rotating member 13 as an example, the first inclined surface 12c of the second rotating member 13 is located at the second end 10b, and is inclined towards the recess 141 (or the first end 10a) of the second rotating member 13 in the direction from the first surface 12a to the second surface 12b.

[0141] In some embodiments, the first rotating member 12 and the second rotating member 13 further have a second inclined surface 12d, which is inclined from the middle of the second surface 12b toward the recess 141, so that the inclination direction of the second inclined surface 12d is at an angle to the inclination direction of the first inclined surface 12c, and the second inclined surface 12d is configured to form a first clearance portion 101a.

[0142] It can be understood that the second inclined surface 12d is inclined from the middle of the second surface 12b towards the recess 141. Here, the recess 141 is a recess 141 of its own structure. That is, the second inclined surface 12d of the first rotating member 12 is inclined from the middle of the second surface 12b towards the recess 141 of the first rotating member 12, rather than towards the recess 141 of the second rotating member 13. The second inclined surface 12d of the second rotating member 13 is inclined from the middle of the second surface 12b towards the recess 141 of the second rotating member 13, rather than towards the recess 141 of the first rotating member 12.

[0143] Since the first clearance portion 101a is formed by a first inclined surface 12c connecting the first surface 12a and the second surface 12b, and the angle between the first inclined surface 12c and the second surface 12b is an obtuse angle, that is, the first inclined surface 12c is set towards the back surface 100b of the display device 100; and since the second inclined surface 12d is inclined from the middle of the second surface 12b towards the recess 141, so that the inclination direction of the second inclined surface 12d is set at an angle to the inclination direction of the first inclined surface 12c, the second inclined surface 12d also faces the back surface 100b of the display device 100. That is, the design of the inclined surface allows the second rotating member 13 and the first rotating member 12 to have a larger rotation range in the direction towards the display surface 100a, thereby allowing the camera module 20 to have a larger extension to the front side, making the viewing angle of the camera module 20 less likely to be blocked, and being able to be used with display devices 100 of more thicknesses, thus facilitating the adaptation of the camera device 200 to different usage scenarios.

[0144] Furthermore, since both the first inclined surface 12c and the second inclined surface 12d are located on the back side 100b facing the display device 100, the rotating bracket 10 presents a relatively continuous and complete plane when viewed from the side where the first surface 12a of the camera device 200 is located, giving the camera device 200 a good overall appearance.

[0145] For ease of understanding, the structures of the first rotating member 12 and the second rotating member 13 will be described separately. First, the first rotating member 12 and the second rotating member 13 have the same structure. Both the first end 10a and the second end 10b have recesses 141. The recesses 141 have first inclined surfaces 12c on both sides and second inclined surfaces 12d at their locations. Optionally, the first rotating member 12 and the second rotating member 13 can have the same structure and dimensions; that is, the first rotating member 12 and the second rotating member 13 can be universal components. This reduces mold costs. When the camera device 200 requires a larger adjustment range, more rotating members can be added. For example, the camera device 200 also includes a third rotating member, which is hinged between the second rotating member 13 and the camera module 20.

[0146] In this embodiment, the first rotating member 12 and the second rotating member 13 generally present a convex shape.

[0147] Continue reading Figure 6 and Figure 7 In some embodiments, both the first rotating member 12 and the second rotating member 13 may include a main body portion 131 and a cover portion 132. The main body portion 131 has a mounting cavity and a first surface 12a. The cover portion 132 is connected to the side of the main body portion 131 opposite to the first surface 12a and covers the mounting cavity. The cover portion 132 has a second surface 12b. A first inclined surface 12c is formed on the main body portion 131, and the second surface 12b is formed on the cover portion 132. Optionally, the cover portion 132 is generally shaped like a convex character to fit the shape of the main body portion 131.

[0148] The rotating component is designed to include a main body 131 and a cover 132. This design allows the main body 131 to form a cavity, reducing weight, while the cover 132 can be set to a different color, such as white, to enhance the appearance of the rotating component.

[0149] In some embodiments, the included angle between the first inclined surface 12c and the second inclined surface 12d and the first surface 12a is α, where α ≥ 45°.

[0150] In some embodiments, the included angle between the first inclined surface 12c and the second inclined surface 12d and the first surface 12a is α, where α < 90°.

[0151] In some embodiments, the included angle between the first inclined surface 12c and the second inclined surface 12d and the first surface 12a is 45°≤α<90°. Optionally, the following conditions may be met: 45°<α<90°, 45°≤α≤80°, or 45°≤α≤60°, etc. For example, α can be 45°, 50°, or 60°, etc.

[0152] If the inclination angles of the first inclined plane 12c and the second inclined plane 12d are too large, the steepness of the inclined planes will reduce the effective load-bearing cross section of the material, thus weakening the structural strength of the rotating component itself. If the inclination angles of the first inclined plane 12c and the second inclined plane 12d are too small, the inclined planes will be too gentle, and the protrusion 151 and the recess 141 may still collide at sharp corners during rotation, thus limiting the maximum rotation angle between the first rotating component 12 and the second rotating component 13.

[0153] Therefore, by reasonably setting the angles of the first inclined plane 12c and the second inclined plane 12d, it can be ensured that the structure remains stable even at the maximum rotation angle, and the deformation or breakage of the rotating parts due to excessive rotation can be avoided.

[0154] It is worth noting that the angle between the first inclined surface 12c and the second inclined surface 12d in this embodiment is affected by the diameter of the rotating shaft 161 and the thickness of the first rotating member 12 and the second rotating member 13. For example, with a rotating shaft 161 having a diameter of 2.8 mm and a rotating member thickness of 5 mm, the angle between the first inclined surface 12c and the second inclined surface 12d can be set to 45°. Figure 8 As shown, at this time, the second rotating member 13 can rotate to the maximum angle in one direction relative to the first rotating member 12.

[0155] See Figure 9 , Figure 9 A partial cross-sectional view of the hinge joint, exemplified by the hinge of the first and second rotating members, is shown. In some embodiments, the first portion 142 has an inner peripheral surface 142b for forming a first shaft hole 142a. A stop portion 142c is provided on the inner peripheral surface 142b. The stop portion 142c is axially arranged around the first shaft hole 142a to form a fourth shaft hole 142d. The stop portion 142c has a third surface 142c1 and a fourth surface 142c2 that are opposite to each other along the axial direction of the first shaft hole 142a.

[0156] Optionally, the stop portion 142c is integrally formed with the first portion 142 and is an annular protrusion protruding on the inner peripheral surface 142b, so that the threaded part 162 abuts against it to prevent the first part 14 and the second part 15 from disengaging from each other.

[0157] In some embodiments, the rotating shaft assembly 16 includes a rotating shaft 161, which includes a head 161a and a rod 161b. The head 161a is located outside the second shaft hole 143a. One end of the rod 161b is connected to the head 161a, and the other end of the rod 161b is provided with a threaded hole 161c. The rod 161b passes through the second shaft hole 143a, the third shaft hole 151a, and the first shaft hole 142a in sequence, so that the first component 14 and the second component 15 can rotate relative to each other.

[0158] In some embodiments, the shaft assembly 16 includes a threaded member 162, one end of which passes through a fourth shaft hole 142d and is connected to a threaded hole 161c.

[0159] Optionally, the threaded component 162 can be a threaded structural component such as a screw or bolt.

[0160] It is worth noting that the threaded part 162 not only has the function of being screwed into the threaded hole 161c of the rotating shaft 161 to prevent the rotating shaft 161 from disengaging from the shaft hole, but can also be used to adjust the tension between the first part 14 and the second part 15 so that the first part 14 and the second part 15 can abut against each other in the first direction X, so that the first part 14 and the second part 15 can be kept in any rotation position when the rotating shaft 161 rotates relative to each other.

[0161] In some embodiments, the rod portion 161b is spaced apart from the third surface 142c1 along the axial direction of the first shaft hole 142a to form a gap between them, and the other end of the threaded member 162 abuts against the fourth surface 142c2. The gap is configured to provide deformation space for the stop portion 142c so that the threaded member 162 and the rotating shaft 161 can achieve self-locking.

[0162] By maintaining a gap between the rod portion 161b and the third surface 142c1 of the stop portion 142c, when the threaded part 162 is tightened, this gap provides a certain deformation space for the stop portion 142c. At this time, the stop portion 142c deforms along the first direction X toward the rod portion 161b. The stop portion 142c then generates a reaction force, subjecting the threaded part 162 to an outward pushing force similar to that of a spring washer, ensuring a self-locking effect after the threaded part 162 and the rotating shaft 161 are locked. It is evident that by replacing the traditional spring washer with a gap design, the self-locking effect between the threaded part 162 and the rotating shaft 161 can be achieved, making the threaded part 162 more difficult to loosen, reducing the number of parts, and lowering costs.

[0163] Specifically, after the rod portion 161b of the rotating shaft 161 passes through the shaft hole in sequence, the rod portion 161b does not directly contact the third surface 142c1 of the stop portion 142c. When the threaded part 162 is screwed into the threaded hole 161c of the rod portion 161b of the rotating shaft 161, its end will press against the fourth surface 142c2 of the stop portion 142c, but it is not fully compressed at this time. As the threaded part 162 continues to be tightened, the axial force of the threaded part 162 pushes the stop portion 142c to undergo elastic micro-deformation. Due to the existence of the gap, the stop portion 142c undergoes elastic bending, generating a reverse force. This reverse force is transmitted to the threaded part 162 through the fourth surface 142c2, forming a self-locking preload force.

[0164] In some embodiments, the surface of the threaded part 162 away from the stop portion 142c is covered with a PET (Polyethylene terephthalate) sheet to improve the appearance of the threaded part 162.

[0165] Optionally, the components used for hinged connection can be made of plastic, such as PC-ABS (Polycarbonate-ABS) or PC (Polycarbonate), which have good toughness. In other words, the mounting part 11, the first rotating part 12, the second rotating part 13, and the connection parts of the camera module 20 with the rotating parts can all be made of plastic with good toughness. This allows the threaded part 162 to be subjected to a reaction force similar to that of a spring washer by the elastic deformation of the hinged components themselves. Without the need for additional spring washers, a self-locking effect can be ensured after the threaded part 162 and the rotating shaft 161 are locked.

[0166] Continue reading Figure 9 In some embodiments, the first portion 142 is provided with a first groove 142e, which corresponds to the first shaft hole 142a. The end of the threaded component 162 is located in the first groove 142e. The second portion 143 is provided with a second groove 143b, in which the second shaft hole 143a is located. The head 161a of the rotating shaft 161 is located in the second groove 143b. This arrangement allows the ends of the rotating shaft 161 and the threaded component 162 to be exposed, giving the camera device 200 a good appearance.

[0167] In some embodiments, the gap D ranges from 0.05 mm to 0.3 mm. Optionally, the gap D between the rod portion 161b of the rotating shaft 161 and the stop portion 142c can be 0.05 mm to 0.2 mm, 0.1 mm to 0.3 mm, or 0.1 mm to 0.2 mm, etc. For example, the gap D can be 0.05 mm, 0.1 mm, 0.2 mm, or 0.3 mm, etc.

[0168] If the gap between the rod portion 161b and the stop portion 142c of the rotating shaft 161 is too small, the third surface 142c1 of the rod portion 161b and the stop portion 142c will be in near contact, or even without gap. When the threaded part 162 is tightened, the stop portion 142c cannot generate sufficient rebound force through elastic deformation, resulting in reduced end-face friction, weakened self-locking effect, and potentially excessive contact between the rod portion 161b and the stop portion 142c, causing rotational jamming. If the gap between the rod portion 161b and the stop portion 142c of the rotating shaft 161 is too large, after the threaded part 162 is tightened, the stop portion 142c will bend excessively, and the deformation of the stop portion 142c will exceed the elastic range, resulting in plastic deformation. The reaction force will drop sharply, and the self-locking effect will be lost.

[0169] Therefore, by limiting the gap range to a reasonable range of 0.05mm to 0.3mm, the preload is ensured to be moderate, so that the threaded part 162 and the rotating shaft 161 maintain a good self-locking effect, and it can prevent the threaded part 162 from being screwed too tight, which would cause rotational jamming, and also avoid the situation of being too loose, which would cause shaking.

[0170] See Figures 10 to 12 In some embodiments, the camera module 20 includes a housing 21 having a receiving cavity 21a and a first mounting hole 21b communicating with the receiving cavity 21a. It is understood that the second rotating member 13 is rotatably connected to the housing 21 to allow the camera module 20 to be adjusted for both overhead and under-view orientations.

[0171] In some embodiments, the camera module 20 includes a camera 22 disposed in a receiving cavity 21a.

[0172] In some embodiments, the camera module 20 includes a circuit board disposed in the receiving cavity 21a and electrically connected to the camera 22.

[0173] In some embodiments, the camera module 20 includes a connecting wire 23, one end of which is used to connect to the display device 100, and the other end of which passes through the first mounting hole 21b into the receiving cavity 21a and is electrically connected to the circuit board.

[0174] In related technologies, the connecting wire 23 of the camera device 200 is usually connected to the camera module 20 via a USB interface for data transmission. However, the USB plug used in this method is expensive and is prone to falling off during the adjustment of the camera module 20, requiring reconnection. Based on this, this application connects one end of the connecting wire 23 to the display device 100, and the other end passes through the first mounting hole 21b into the receiving cavity 21a to be electrically connected to the circuit board. That is, the connecting wire 23 eliminates the USB plug and directly connects to the circuit board inside the camera module 20, which not only saves costs but also avoids the possibility of the connecting wire 23 and the camera 22 becoming loose or even falling off due to the adjustment of the camera module 20.

[0175] In some embodiments, the outer casing 21 includes a housing 211, the housing 211 having a receiving cavity 21a and a first opening 211a communicating with the receiving cavity 21a, the housing 211 having a first notch 211b located at the first opening 211a, the housing 211 also having a first inner wall 211c for forming the first notch 211b, and a first slot 211d provided on the first inner wall 211c;

[0176] In some embodiments, the housing 21 includes a cover plate 212 located at the first opening 211a and connected to the housing 211. The cover plate 212 has a second notch 212a and a second inner wall 212b for forming the second notch 212a. The second inner wall 212b has a second slot 212c. The second notch 212a and the first notch 211b are disposed opposite to each other to jointly enclose and form a first mounting hole 21b. The first slot 211d and the second slot 212c are disposed opposite to each other.

[0177] Optionally, the cover plate 212 and the housing 21 can be connected by snap-fit, screw-fit, or a combination of snap-fit ​​and screw-fit to achieve a reliable connection between the cover plate 212 and the housing 21.

[0178] In some embodiments, a latching protrusion 23a is provided on the outer peripheral surface of the connecting wire 23, and the latching protrusion 23a is engaged in the first latching groove 211d and the second latching groove 212c.

[0179] Optionally, both the first slot 211d and the second slot 212c are semi-circular, so that the first slot 211d and the second slot 212c are arranged opposite each other to form a circular space. Correspondingly, the protrusion 23a on the connecting wire 23 is also an annular protrusion, so that the connecting wire 23 has a larger contact area with the outer shell 21 and the cover plate 212, so that the connection between the connecting wire 23 and the first mounting hole 21b is more reliable.

[0180] Because the connecting wire 23 is directly inserted into the receiving cavity 21a to connect with the circuit board, the connecting wire 23 forms shear force at the hard-soft interface with the rigid circuit board and the first mounting hole 21b. This can easily lead to a low bending test life of the connecting wire 23, causing fatigue fracture at the root of the connecting wire 23 due to repeated bending.

[0181] To address this issue, this application provides opposing first slots 211d and second slots 212c on the inner walls of the first notch 211b and the second notch 212a on the housing 211 and the cover plate 212, respectively. A protrusion 23a is provided on the outer circumferential surface of the connecting wire 23. On one hand, after the connecting wire 23 extends into the receiving cavity 21a and connects to the circuit board, the protrusion 23a is positioned within the two slots. The housing 211 and the cover plate 212 close together, causing the protrusion 23a to be securely locked within the space formed by the first slot 211d and the second slot 212c. Thus, the positioning structure of the first mounting hole 21b makes the fixing of the connecting wire 23 more reliable, reducing the degree of radial bending and thereby increasing the bending test life of the connecting wire 23. Furthermore, the design of the protrusion 23a on the outer circumferential surface thickens the portion connecting the connecting wire 23 to the mounting hole, further increasing the bending test life of the connecting wire 23. Furthermore, the engagement of the protrusion 23a with the slot releases a portion of the bending stress from the connection point between the circuit board and the connecting wire 23 to the engagement point, thereby reducing the degree of bending of the connecting wire 23.

[0182] Furthermore, the positioning structure formed by the first slot 211d and the second slot 212c makes the fixing of the connecting wire 23 more reliable, prevents the axial movement of the connecting wire 23, and also reduces the wear of the connecting wire 23.

[0183] In some embodiments, the cover plate 212 is used to rotatably connect with the second rotating member 13. That is, the cover plate 212 has a recess 141 and a first portion 142 and a second portion 143 located on both sides of the recess 141 to achieve rotatable connection with the second rotating member 13.
