Description

Technical Field

[0001] This invention relates to a camera lifting structure and a display device equipped with the camera lifting structure. Background Technology

[0002] With the advancement of display technology, modern display devices are gradually moving towards borderless or narrow-bezel and thinner designs. This results in very limited space inside the display device to accommodate various components. As a result, traditionally space-consuming components, such as pop-up cameras, are gradually becoming unsuitable for the needs of today's thinner display devices. They are not only prone to interference with internal circuit components during assembly, but may also cause problems such as electromagnetic interference or poor heat dissipation due to their close proximity to internal circuit components.

[0003] Therefore, how to design a new camera lifting structure to achieve better space utilization in the internal structure of thin display devices is undoubtedly an important issue of great concern to the industry. Summary of the Invention

[0004] One of the objectives of this invention is to provide a camera lifting structure that can effectively reduce the size of the camera within a display device, thereby saving internal space when the camera lifting structure is installed in the display device.

[0005] According to one embodiment of the present invention, a camera lifting structure includes a guide rail, two fixed portions, two elastic elements, two sliding portions, two connecting rods, and a camera module. The guide rail extends along a first direction and is configured to connect to a display device. The fixed portions are disposed at opposite ends of the guide rail along the first direction. The elastic elements are located between the fixed portions and extend along the first direction, each elastic element having an opposite first end and a second end, the first end being connected to a corresponding fixed portion. The sliding portions are respectively connected to corresponding second ends and configured to slide relative to the guide rail along the first direction. The connecting rods have opposite third ends and fourth ends, the third end being pivotally connected to a corresponding sliding portion. The camera module is pivotally connected to the fourth end and configured to move relative to the guide rail along a second direction, the second direction being perpendicular to the first direction.

[0006] In one or more embodiments of the present invention, the above-described camera lifting structure further includes a guide rod. This guide rod is connected between the fixed parts along a first direction and passes through the elastic element and the sliding part.

[0007] In one or more embodiments of the present invention, the above-described camera lifting structure further includes two protrusions, a damping module, and two auxiliary connecting rods. The protrusions are respectively disposed on corresponding connecting rods and located between corresponding third and fourth ends. The damping module includes a housing, two rotating shafts, a cover, and multiple protrusions. The housing is connected to a guide rail and has two spaces therein. The rotating shaft includes a first sub-rotating shaft and a second sub-rotating shaft, the first sub-rotating shaft and the corresponding second sub-rotating shaft extending along an axis, the first sub-rotating shaft located within a corresponding space, and the second sub-rotating shaft protruding outside the housing. The cover is connected to the housing to seal the spaces. The protrusions are disposed on the first sub-rotating shaft and extend along corresponding axes, the protrusions being separate from each other. The auxiliary connecting rod has opposing fifth and sixth ends, the fifth end connecting to the corresponding second sub-rotating shaft, and the auxiliary connecting rod has a groove extending between the corresponding fifth and sixth ends. The protrusions are at least partially located within the corresponding grooves.

[0008] In one or more embodiments of the present invention, the damping module further includes two first limiting portions and two pairs of second limiting portions. The first limiting portions are respectively located on corresponding first sub-rotating shafts. The second limiting portions are connected to the cover and are located within corresponding spaces, while the first limiting portions are constrained between the corresponding second limiting portions.

[0009] In one or more embodiments of the present invention, the camera lifting structure further includes two buffer pads and a central portion. The buffer pads are located between the sliding portions and are respectively disposed on the corresponding sliding portions. The central portion is disposed on the guide rail and is at least partially located between the buffer pads, and the housing is at least partially located within the central portion.

[0010] In one or more embodiments of the present invention, the above-described camera lifting structure further includes a first latching part, a torsion spring, and a second latching part. The first latching part is pivotally connected to the camera module. The torsion spring is elastically connected between the camera module and the first latching part. The second latching part is disposed in the central part and configured to latch against the first latching part.

[0011] In one or more embodiments of the present invention, the guide rail includes a first sub-guide rail and a second sub-guide rail. The first sub-guide rail has a first groove and extends along a first direction. The second sub-guide rail has a second groove and extends along the first direction. A sliding portion is located between the first sub-guide rail and the second sub-guide rail. The sliding portion includes a body, a plurality of first balls, and a plurality of second balls. The body is connected to a corresponding second end. The first balls are rotatably disposed on the body and configured to roll in the first groove. The second balls are rotatably disposed on the body and configured to roll in the second groove.

[0012] In one or more embodiments of the present invention, the material of the above-mentioned body is polyoxymethylene.

[0013] In one or more embodiments of the present invention, the camera module further includes a camera and a ring structure. The ring structure is connected to the camera along a second direction. The camera lifting structure further includes at least one line connecting the camera and the display device, and passing through the ring structure.

[0014] One of the objectives of this invention is to provide a display device that can effectively reduce the size of the camera lifting structure housed within its main body, so that when the camera lifting structure is installed in the display device, it can effectively save the internal space of the display device.

[0015] According to one embodiment of the present invention, a display device includes a main body and a camera lifting structure. The main body has an opening. The camera lifting structure is at least partially disposed within the main body. The camera lifting structure includes a guide rail, two fixed portions, two elastic elements, two sliding portions, two connecting rods, and a camera module. The guide rail extends along a first direction. The fixed portions are disposed at opposite ends of the guide rail along the first direction. The elastic elements are located between the fixed portions and extend along the first direction, and each elastic element has an opposite first end and a second end, the first end being connected to a corresponding fixed portion. The sliding portions are respectively connected to corresponding second ends and configured to slide relative to the guide rail along the first direction. The connecting rods have opposite third ends and fourth ends, the third end being pivotally connected to a corresponding sliding portion. The camera module is pivotally connected to the fourth end and configured to move relative to the guide rail along a second direction to protrude out of the main body through the opening, the second direction being perpendicular to the first direction.

[0016] The above-described embodiments of the present invention have at least the following advantages:

[0017] (1) Since the camera module moves along the guide rail or away from the guide rail in the second direction to switch between the storage state and the use state, this corresponds to the sliding part sliding along the first direction and the compression and extension of the elastic element along the first direction. Therefore, the size of the camera lifting structure disposed in the main body of the display device in the second direction can be effectively reduced. Thus, when the camera lifting structure is installed in the main body of the display device, it can effectively save the internal space of the display device and avoid contact with other internal components that could cause damage.

[0018] (2) When the connecting rod rotates relative to the camera module and the sliding part, at least part of the protrusion located in the groove of the auxiliary connecting rod also moves within the groove of the auxiliary connecting rod along with the connecting rod, causing the auxiliary connecting rod to rotate relative to the damping module. Since the damping module provides damping for the rotation of the auxiliary connecting rod, the rotation of the connecting rod relative to the camera module and the sliding part is also affected by the damping effect. In this way, the speed at which the sliding part slides toward each other or toward the fixed part in the first direction and the speed at which the camera module moves toward or away from the guide rail in the second direction are both controlled, and the movement of the camera module toward or away from the guide rail in the second direction becomes smoother.

[0019] (3) Since the line passes through the ring structure and is surrounded by the ring structure, when the camera module moves relative to the guide rail in the second direction, the line connecting the camera and the display device will not get tangled or pulled with the display device or other parts of the camera lifting structure, thus avoiding damage or even disconnection of the line.

For clarity, many practical details will be described in the following description. However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and elements will be shown in the drawings in a simple schematic manner, and in all drawings, the same reference numerals will be used to denote the same or similar elements. And, where feasible, features of different embodiments can be interchanged.

[0090] Unless otherwise defined, all terms used herein (including technical and scientific terms) have their ordinary meanings, meanings that are understandable to those skilled in the art. Furthermore, the definitions of the foregoing terms in commonly used dictionaries should be interpreted in the context of this specification as having the meaning consistent with the relevant field of this invention. Unless specifically defined, these terms will not be construed as having idealized or overly formal meanings.

[0091] Please refer to Figures 1-3 . Figure 1 This is a frontal perspective three-dimensional schematic diagram of a camera lifting structure 100 according to an embodiment of the present invention. Figure 2 For illustration Figure 1 A rear-view stereoscopic diagram of the camera lifting structure 100. Figure 3 For illustration Figure 1 An exploded view of the camera lifting structure 100. In this embodiment, as... Figures 1-3 As shown, a camera lifting structure 100 includes a guide rail 110, two fixing parts 115, two elastic elements 120, two sliding parts 130, two connecting rods 140, and a camera module 150. The guide rail 110 extends along a first direction D1 and is configured to connect to a display device 200 (see [link]). Figures 4-5(15). Fixing portions 115 are disposed at opposite ends of the guide rail 110 along a first direction D1. Elastic elements 120 are located between the fixing portions 115 and extend along the first direction D1. Specifically, the elastic element 120 may be a spring, but the invention is not limited thereto. Furthermore, the elastic element 120 has opposing first ends 120a and second ends 120b, with the first end 120a connected to the corresponding fixing portion 115. Sliding portions 130 are respectively connected to the corresponding second ends 120b of the elastic element 120 and configured to slide relative to the guide rail 110 along the first direction D1 by the elasticity of the elastic element 120. Connecting rods 140 have opposing third ends 140a and fourth ends 140b, with the third end 140a of the connecting rod 140 pivotally connected to the corresponding sliding portion 130. The camera module 150 is pivotally connected to the fourth end 140b of the connecting rod 140 and configured to move relative to the guide rail 110 along a second direction D2 under the action of the connecting rod 140, the second direction D2 being perpendicular to the first direction D1.

[0092] Structurally speaking, such as Figure 3 As shown, the camera lifting structure 100 also includes a guide rod 155. The guide rod 155 is connected between the fixed portions 115 along the first direction D1 and passes through the elastic element 120 and the sliding portion 130. Therefore, the sliding portion 130 slides relative to the guide rail 110 along the guide rod 155. In this way, the sliding portion 130 and the elastic element 120 will not detach from the guide rail 110.

[0093] Furthermore, in this embodiment, the camera lifting structure 100 also includes at least one washer 195. For example... Figure 1 , 3 As shown, the washer 195 is connected between the corresponding fixing part 115 and the corresponding elastic element 120. By applying different numbers of washers 195, the elastic potential energy of the elastic element 120 can be adjusted according to the situation.

[0094] Furthermore, in this embodiment, such as Figures 1-3 As shown, the camera module 150 also includes a camera 151 and a ring structure 152. The camera 151 is configured to capture images. The ring structure 152 is connected to the camera 151 along the second direction D2. Furthermore, the camera lifting structure 100 also includes at least one line 190, which passes through the ring structure 152 and connects the camera 151 to the display device 200 (see...). Figures 4-5 Between 1 and 15), for example, line 190 is connected to the motherboard (not shown) of display device 200. Furthermore, for example, such as... Figures 1-3As shown, the camera lifting structure 100 includes two lines 190, which can actually be electrical wires or flexible flat cables (FFC), etc., but the present invention is not limited thereto.

[0095] Because the line 190 passes through and is surrounded by the ring structure 152, when the camera module 150 moves relative to the guide rail 110 along the second direction D2, the line 190 connecting the camera 151 and the display device 200 will not become entangled or pulled with the display device 200 or other components of the camera lifting structure 100, thus avoiding damage or even breakage to the line 190. Furthermore, the ring structure 152 can be a complete ring or a partial ring, but the present invention is not limited thereto.

[0096] In this embodiment, such as Figures 1-3 As shown, the camera lifting structure 100 also includes two buffer pads 135 and a central portion 175. The buffer pads 135 are located between the sliding portions 130 and are respectively disposed on the corresponding sliding portions 130. The central portion 175 is disposed on the guide rail 110 and is at least partially located between the buffer pads 135. Therefore, when the sliding portions 130 slide relative to the guide rail 110 toward each other and reach the central portion 175, the buffer pads 135 disposed on the sliding portions 130 will press against the central portion 175 and buffer the impact force exerted by the sliding portions 130 on the central portion 175. In this way, when the buffer pads 135 of the sliding portions 130 abut against the central portion 175 to stop the sliding portions 130, the buffer pads 135 can effectively prevent excessive impact noise caused by the sliding portions 130 hitting the central portion 175.

[0097] Please refer to Figures 4-5 . Figure 4 For illustration Figure 1 A front view of the camera lifting structure 100, wherein the camera module 150 protrudes at least partially from the display device 200. Figure 5 For illustration Figure 1 The diagram shows a front view of the camera lifting structure 100, in which the camera module 150 is completely housed within the display device 200. For clarity and simplicity, the diagram is shown below. Figures 4-5 In the diagram, the camera module 150 is shown only with dashed lines, and the wiring 190 is not shown. Figures 4-5 In this embodiment, as... Figures 4-5 As shown, the display device 200 includes a camera lifting structure 100 and a main body 210. The main body 210 has an opening OP, and the camera lifting structure 100 is at least partially disposed within the main body 210 of the display device 200. Furthermore, the camera lifting structure 100 can be switched between a usage state and a storage state. Figure 4As shown, the camera module 150 is in use, and the camera 151 of the camera module 150 protrudes at least partially from the body 210 of the display device 200 through the opening OP of the body 210 to capture images. Figure 5 As shown, when not recording images, the camera module 150 is in a retracted state and is completely stored inside the display device 200.

[0098] Specifically, such as Figures 1-5 As shown, the camera lifting structure 100 also includes two protrusions 145, a damping module 160, and two auxiliary connecting rods 170. The protrusions 145 are respectively disposed on the corresponding connecting rods 140 and located between the corresponding third end 140a and the corresponding fourth end 140b. The auxiliary connecting rods 170 have opposing fifth ends 170a and sixth ends 170b. The fifth end 170a of the auxiliary connecting rod 170 is connected to the damping module 160, which provides damping for the rotation of the auxiliary connecting rod 170. Notably, the auxiliary connecting rod 170 has a groove SL extending between the corresponding fifth end 170a and the corresponding sixth end 170b, and the protrusions 145 are at least partially located within the corresponding groove SL.

[0099] When the camera lifting structure 100 is in use (e.g.) Figure 4 (As shown) Switch to storage mode (e.g.) Figure 5 When the user applies pressure to the camera module 150 (as shown), the camera module 150 moves along the second direction D2 toward the guide rail 110. As the camera module 150 moves along the second direction D2 toward the guide rail 110, since the third end 140a and the fourth end 140b of the connecting rod 140 are respectively pivotally connected to the corresponding sliding part 130 and the camera module 150, the connecting rod 140 rotates relative to the camera module 150 and the sliding part 130, and pushes the sliding part 130 to slide along the first direction D1 toward the fixed part 115. In this way, the elastic element 120 is compressed and stores some elastic potential energy until the camera lifting structure 100 is completely switched to the retracted state.

[0100] Furthermore, as described above, the protrusion 145 provided on the connecting rod 140 is at least partially located within the groove SL of the auxiliary connecting rod 170. Therefore, when the connecting rod 140 rotates relative to the camera module 150 and the sliding part 130, the protrusion 145 also moves within the groove SL of the auxiliary connecting rod 170 along with the connecting rod 140, causing the auxiliary connecting rod 170 to rotate relative to the damping module 160. Since the damping module 160 provides damping for the rotation of the auxiliary connecting rod 170, the rotation of the connecting rod 140 relative to the camera module 150 and the sliding part 130 is also affected by the damping effect. In this way, the speed at which the sliding part 130 slides towards the fixed part 115 along the first direction D1 and the speed at which the camera module 150 moves towards the guide rail 110 along the second direction D2 are both controlled, and the movement of the camera module 150 towards the guide rail 110 along the second direction D2 becomes smoother.

[0101] When the camera lifting structure 100 is in its retracted state (e.g.) Figure 5 (As shown) Switch to usage mode (e.g.) Figure 4 When the elastic element 120 is in use (as shown), the elastic potential energy stored in the elastic element 120 will be released, causing the elastic element 120 to extend elastically and the sliding part 130 to slide relative to the guide rail 110. Since the third end 140a and the fourth end 140b of the connecting rod 140 are respectively pivotally connected to the corresponding sliding part 130 and the camera module 150, the connecting rod 140 rotates relative to the camera module 150 and the sliding part 130, and pushes the camera module 150 away from the guide rail 110 along the second direction D2 until the camera lifting structure 100 is fully switched to the use state.

[0102] Furthermore, as described above, the protrusion 145 provided on the connecting rod 140 is at least partially located within the groove SL of the auxiliary connecting rod 170. Therefore, when the connecting rod 140 rotates relative to the camera module 150 and the sliding part 130, the protrusion 145 also moves within the groove SL of the auxiliary connecting rod 170 along with the connecting rod 140, causing the auxiliary connecting rod 170 to rotate relative to the damping module 160. Since the damping module 160 provides damping for the rotation of the auxiliary connecting rod 170, the rotation of the connecting rod 140 relative to the camera module 150 and the sliding part 130 is also affected by the damping effect. In this way, the speed at which the sliding parts 130 slide toward each other and the speed at which the camera module 150 moves away from the guide rail 110 along the second direction D2 are both controlled, and the movement of the camera module 150 away from the guide rail 110 along the second direction D2 becomes smoother.

[0103] Please refer to Figures 6-8 . Figure 6 For illustration Figure 4 An enlarged 3D schematic diagram of the damping module 160. Figure 7 For illustration Figure 6Exploded view of the damping module 160. Figure 8 For illustration Figure 6 A cross-sectional view along line segment AA. In this embodiment, as... Figures 6-8 As shown, the damping module 160 includes a housing 161, two rotating shafts 162, and a plurality of protrusions 163. The housing 161 is connected to the guide rail 110 and is at least partially located within the central portion 175, and the housing 161 has two spaces SP therein. The rotating shafts 162 include a first sub-rotating shaft 1621 and a second sub-rotating shaft 1622, the first sub-rotating shaft 1621 and the corresponding second sub-rotating shaft 1622 extending along the axis XL. The first sub-rotating shaft 1621 is located within the corresponding space SP, and the second sub-rotating shaft 1622 protrudes outside the housing 161. The fifth end 170a of the auxiliary connecting rod 170 is connected to the corresponding second sub-rotating shaft 1622, so the rotating shaft 162 can rotate relative to the housing 161 with the auxiliary connecting rod 170. The protrusions 163 are disposed on the first sub-rotating shaft 1621 and extend along the corresponding axis XL, and the protrusions 163 are separate from each other. Therefore, when the space SP of the housing 161 is filled with oil, the rotation of the shaft 162 will be damped by the resistance of the oil to the protrusion 163. In this embodiment, the damping module 160 also includes a cover 166, which is connected to the housing 161 to seal the space SP.

[0104] Please refer to Figure 9 . Figure 9 For illustration Figure 6 A cross-sectional view along line segment BB. In this embodiment, as... Figure 9 As shown, the damping module 160 also includes two first limiting parts 164 and two pairs of second limiting parts 165. The first limiting parts 164 are respectively located on the corresponding first sub-shafts 1621. Figure 7 As shown, the second limiting part 165 is located within the corresponding space SP, and as... Figure 7 The connecting cover 166 is shown. In this embodiment, the first limiting part 164 is limited between the corresponding second limiting parts 165. That is, the rotation of the rotating shaft 162 relative to the housing 161 is limited by the second limiting parts 165 in a stop manner.

[0105] Please refer to Figures 10-11 . Figure 10 For illustration Figure 5 A cross-sectional view of line segment CC. Figure 11 For illustration Figure 10 An exploded view of the sliding portion 130. In this embodiment, as... Figures 10-11As shown, guide rail 110 includes a first sub-guide rail 1101 and a second sub-guide rail 1102. The first sub-guide rail 1101 has a first groove G1 and extends along a first direction D1. The second sub-guide rail 1102 has a second groove G2 and extends along the first direction D1. A sliding portion 130 is located between the first sub-guide rail 1101 and the second sub-guide rail 1102. The sliding portion 130 includes a body 131, a plurality of first balls 132, and a plurality of second balls 133. The body 131 is connected to a corresponding second end 120b. The first balls 132 are rotatably disposed on the body 131 and configured to roll in the first groove G1. The second balls 133 are rotatably disposed on the body 131 and configured to roll in the second groove G2. In this embodiment, for example, Figure 11 As shown, the first ball 132 and the second ball 133 can be disposed on the body 131 through the plate 134, but the present invention is not limited thereto.

[0106] In practical applications, the material of the body 131 can be a dimensionally stable and wear-resistant material, such as polyoxymethylene (POM), but the present invention is not limited thereto.

In this embodiment, as... Figures 12-13 As shown, the camera lifting structure 100 also includes a first latching part 181, a torsion spring 183, and a second latching part 185. The first latching part 181 is pivotally connected to the camera module 150. The torsion spring 183 is elastically connected between the camera module 150 and the first latching part 181. The second latching part 185 is disposed in the central part 175 and configured to latch with the first latching part 181. When the first latching part 181 and the second latching part 185 latch with each other, the camera module 150 will not move relative to the guide rail 110, and the camera lifting structure 100 is completely housed within the display device 200 and is in a retracted state.

[0108] Please refer to Figure 14 . Figure 14 For illustration Figure 12 A partially enlarged perspective view of the area M, showing that the first latch 181 has disengaged from the second latch 185. When the camera lifting structure 100 is in its retracted state (e.g., Figure 5 (As shown) Switch to usage mode (e.g.) Figure 4 When (as shown), the user applies pressure to the camera module 150 toward the guide rail 110. In this embodiment, as... Figure 14As shown, when the user applies pressure to the camera module 150 towards the guide rail 110, the first latching part 181 rotates elastically relative to the camera module 150 due to pressing against the second latching part 185, causing the first latching part 181 to disengage from the second latching part 185. At this time, the elastic potential energy stored in the elastic element 120 is released, causing the elastic element 120 to extend elastically and the sliding part 130 to slide relative to the guide rail 110. When the buffer pad 135 of the sliding part 130 abuts against the central part 175 to stop the sliding part 130, the camera lifting structure 100 is fully switched to the use state, and the camera 151 protrudes at least partially from the main body 210 of the display device 200 through the opening OP of the main body 210 to capture images.

[0109] Conversely, when the camera lifting structure 100 is in use (e.g., Figure 4 (As shown) Switch to storage mode (e.g.) Figure 5 When the user applies pressure to the camera module 150, the camera module 150 moves along the second direction D2 through the opening OP of the main body 210 toward the guide rail 110 until the first latching part 181 and the second latching part 185 latch each other, and the camera lifting structure 100 is completely stored in the display device 200 and is in the stored state.

[0110] Please refer to Figure 15 . Figure 15 This is a comparative schematic diagram illustrating a display device 200 according to an embodiment of the present invention and a conventional display device 300. For example... Figure 15 As shown, the display device 200 is located on the right side of the figure, while the conventional display device 300 is located on the left side. It is worth noting that in this embodiment, since the camera module 150 moves along the second direction D2 towards or away from the guide rail 110 to switch between a storage state and a usage state, this corresponds to the sliding of the sliding part 130 along the first direction D1 and the compression and extension of the elastic element 120 along the first direction D1. Therefore, compared to the camera lifting structure 310 in the conventional display device 300, the size of the camera lifting structure 100 disposed within the main body 210 of the display device 200 in the second direction D2 can be effectively reduced. Specifically, as... Figure 15 As shown, the length LN of the camera lifting structure 100 within the display device 200 is significantly smaller than the length LO of the traditional camera lifting structure 310 within the display device 300. Therefore, when the camera lifting structure 100 is installed on the main body 210 of the display device 200, it can effectively save the internal space of the display device 200 and avoid damage caused by contact with other internal components.

[0111] In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:

[0112] (1) Since the camera module moves along the guide rail or away from the guide rail in the second direction to switch between the storage state and the use state, this corresponds to the sliding part sliding along the first direction and the compression and extension of the elastic element along the first direction. Therefore, the size of the camera lifting structure disposed in the main body of the display device in the second direction can be effectively reduced. Thus, when the camera lifting structure is installed in the main body of the display device, it can effectively save the internal space of the display device and avoid contact with other internal components that could cause damage.

[0113] (2) When the connecting rod rotates relative to the camera module and the sliding part, at least part of the protrusion located in the groove of the auxiliary connecting rod also moves within the groove of the auxiliary connecting rod along with the connecting rod, causing the auxiliary connecting rod to rotate relative to the damping module. Since the damping module provides damping for the rotation of the auxiliary connecting rod, the rotation of the connecting rod relative to the camera module and the sliding part is also affected by the damping effect. In this way, the speed at which the sliding part slides toward each other or toward the fixed part in the first direction and the speed at which the camera module moves toward or away from the guide rail in the second direction are both controlled, and the movement of the camera module toward or away from the guide rail in the second direction becomes smoother.

[0114] (3) Since the line passes through the ring structure and is surrounded by the ring structure, when the camera module moves relative to the guide rail in the second direction, the line connecting the camera and the display device will not get tangled or pulled with the display device or other parts of the camera lifting structure, thus avoiding damage or even disconnection of the line.

[0115] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Any person skilled in the art may make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the appended claims.
