[0061] Please refer to Figures 1 to 6 . Figure 1 It is a schematic plan view of the functional component 300 of the electronic device 1 according to the first embodiment of the present invention extending out of the body 10. Figure 2 It is Figure 1 a perspective plan view of the telescopic component 20. Figure 3 It is Figure 2 a partial perspective three-dimensional schematic view. Figure 4 It is a schematic sectional view along the 4-4 cutting plane line of Figure 3 . Figure 5 It is Figure 3 a schematic sectional view along the 5-5 cutting plane line. Figure 6 It is Figure 3 a schematic sectional view along the 6-6 cutting plane line.

[0062] As Figure 1As shown, the electronic device 1 of this embodiment includes a body 10 and a telescopic assembly 20. The body 10 is, for example, a display, but is not limited thereto. In other embodiments, the electronic device may be a mobile phone, a notebook computer, or a tablet computer. The telescopic assembly 20 includes a fixed frame 100, a movable frame 200, a functional member 300, and a plurality of first balls 400.

[0063] As Figure 2 shown in connection with Figure 3 As shown, the fixed frame 100 is fixed within the body 10 and has a receiving groove 101 and an opening portion 102. Specifically, the fixed frame 100 includes a bottom plate 110 and two side plates 120. The two side plates 120 are respectively connected to opposite sides of the bottom plate 110, such that the bottom plate 110 and the two side plates 120 together define the receiving groove 101 and the opening portion 102. The opening portion 102 communicates with the receiving groove 101.

[0064] Each of the two side plates 120 of the fixed frame 100 has a plurality of sliding grooves 121 and a plurality of loading and unloading grooves 122. These sliding grooves 121 are located on opposite sides of the receiving groove 101 and communicate with the receiving groove 101. The extending direction E1 of these sliding grooves 121 is substantially perpendicular to the normal direction N of the bottom plate 110. These loading and unloading grooves 122 are respectively connected to the sliding grooves 121, and the extending direction E2 of these loading and unloading grooves 122 is substantially parallel to the normal direction N of the bottom plate 110.

[0065] As Figure 1 shown in connection with Figures 3 to 6 As shown, the movable frame 200 is movably located in the receiving groove 101 along sliding directions S1, S2, and extends out of or retracts into the opening portion 102. The movable frame 200 has two side surfaces 210 and a plurality of grooves 220. The two side surfaces 210 face away from each other and respectively face the two side plates 120 of the fixed frame 100. These grooves 220 are respectively located on the two side surfaces 210.

[0066] The functional member 300 is fixed to the movable frame 200, and the functional member 300 is, for example but not limited to, an electrical connector, such as TYPE-C or HDMI. In other embodiments, the functional member may also be a camera or a machine with other functions.

[0067] These first balls 400 are movably located in these sliding grooves 121. And the movable frame 200 is connected to the fixed frame 100 through these first balls 400. Specifically, a partial block of these first balls 400 is located in these grooves 220, and another partial block of these first balls 400 is located in these sliding grooves 121. That is to say, for each first ball 400, each first ball 400 has a partial volume located in the groove 220 and another partial volume located in the sliding groove 121.

[0068] In this embodiment, the depth T of the groove 220 is greater than half of the diameter D of the first ball 400 and less than or equal to the diameter D of these first balls 400. Moreover, these grooves 220 are provided with lubricating fluid. The balls are small in size and light in weight, and the gravity of the balls is less than the capillary tension of the lubricating fluid. Therefore, the first balls 400 can be pre-retained in the grooves 220 by the capillary tension of the lubricating fluid.

[0069] In addition, when the movable frame 200 is to be installed in the fixed frame 100, the first balls 400 pre-retained in the grooves 220 can be first slid into these sliding grooves 121 from these loading and unloading grooves 122 respectively. In this way, the movable frame 200 can be quickly loaded into the receiving groove 101 of the fixed frame 100.

[0070] In this embodiment, these sliding grooves 121 are formed by stamping two side plates 120, and each side edge of these sliding grooves 121 has a rounded corner structure 123. These first balls 400 abut against these rounded corner structures 123. In this way, during the sliding process of the movable frame 200, the wear of the balls can be reduced through the rounded corner structures 123. However, the rounded corner structures 123 of this embodiment are not intended to limit the present invention. In other embodiments, the two side plates may not have rounded corner structures at the side edges of these sliding grooves.

[0071] In this embodiment, the movable frame 200 is separated from the bottom plate 110 of the fixed frame 100. In this embodiment, the telescopic assembly 20 may further include two second balls 500. The movable frame 200 has a bottom surface 240 and two grooves 250. The bottom surface 240 faces the bottom plate 110 of the fixed frame 100, and the two grooves 250 are located on the bottom surface 240. Similar to the method of arranging the first balls in the grooves 220, lubricating oil can also be provided in the grooves 250, so that the second balls can also be pre-retained in the grooves 250 by the capillary tension of the lubricating oil.

[0072] The second balls 500 are located in the grooves 250, and the movable frame 200 can be connected to the bottom plate 110 of the fixed frame 100 through the second balls 500. In this way, when the second balls 500 are connected to the bottom plate 110 of the fixed frame 100, the fixed frame 100 can additionally use the second balls 500 as the support of the movable frame 200 in the Z direction. For example, when the first balls 400 are not worn or have less wear, the second balls 500 are not yet connected to the bottom plate 110 of the fixed frame 100. When the wear degree of the first balls 400 increases, the second balls 500 are then connected to the bottom plate 110 of the fixed frame 100.

[0073] As Figure 2As shown, in this embodiment, the connection line L of the two second balls 500 is not parallel to the sliding direction S1. That is to say, the two second balls 500 are arranged diagonally with respect to the movable frame 200, but this is not limiting. In other embodiments, the connection line of the two second balls may also be parallel to the sliding direction S1.

[0074] In this embodiment, the fixed frame 100 is connected to the movable frame 200 only through the first balls 400 and the second balls 500, so that the movable frame 200 can move relative to the fixed frame 100 more smoothly. In addition, since the wear of the balls is small, the service life and quality of the telescopic assembly 20 can be extended. Since the cost of the balls is low, the market competitiveness of the telescopic assembly 20 can be improved.

[0075] In this embodiment, the number of the second balls 500 is taken as two as an example, but this is not limiting. In other embodiments, the number of the second balls can also be changed to more than three or a single one.

[0076] In this embodiment, the telescopic assembly 20 further includes the second balls 500, but this is not limiting. In other embodiments, the telescopic assembly may not include the second balls, but instead the movable frame is directly suspended above the bottom plate.

[0077] In this embodiment, the telescopic assembly 20 may further include a push-push mechanism 600. The push-push mechanism 600 is fixed to the bottom plate 110 of the fixed frame 100. The movable frame 200 has a buckle portion 230. The user, for example, presses the movable frame 200 to engage the buckle portion 230 with the push-push mechanism 600 or to release the engagement relationship between the buckle portion 230 and the push-push mechanism 600. In this embodiment, the telescopic assembly 20 includes the push-push mechanism 600, but this is not limiting. In other embodiments, the telescopic assembly may not be provided with the push-push mechanism 600, but instead, by other buckling means, the movable frame is kept retracted into the fixed frame.

[0078] In this embodiment, the telescopic assembly 20 may further include a guiding assembly 700. The guiding assembly 700 includes a gear 710 and a rack 720. The gear 710 is rotatably disposed on the bottom plate 110 of the fixed frame 100, and the rack 720 is mounted on the movable frame 200. The rack 720 meshes with the gear 710 to guide the movable frame 200 to move relative to the fixed frame 100.

[0079] In this embodiment, the telescopic assembly 20 includes the guiding assembly 700, but this is not limiting. In other embodiments, the telescopic assembly may not be provided with the guiding assembly 700.

[0080] In this embodiment, the telescopic assembly 20 may further include two elastic members 800. The elastic member 800 is, for example, a tension spring, and the opposite ends of the elastic member 800 are respectively connected to the fixed frame 100 and the movable frame 200, so as to drive the movable frame 200 to extend out of the opening 102 of the fixed frame 100 when the latching portion 230 and the pushing mechanism 600 are disengaged.

[0081] In this embodiment, the number of the elastic members 800 is two, but it is not limited thereto. In other embodiments, the number of the elastic members may also be only one, or no elastic member is provided.

[0082] Please refer to Figures 1 to 3 and Figures 7 to 9 。 Figure 7 is Figure 1 a perspective plan view of the functional member 300 of the telescopic assembly 20 retracted into the fixed frame 100. Figure 8 is Figure 7 a perspective three-dimensional view. Figure 9 is Figure 1 a plan view of the functional member 300 of the electronic device 1 retracted into the body 10.

[0083] As Figures 1 to 3 shown, when the user wants to use the functional member 300, the movable frame 200 can be pressed from below the body 10 to disengage the latching portion 230 of the movable frame 200 from the pushing mechanism 600, and the elastic force of the elastic member 800 is used to drive the movable frame 200 and the functional member 300 to extend out of the body 10 along the sliding direction S1. In this way, the user can directly plug the wire into the functional member 300 on the front of the body 10.

[0084] Since the movable frame 200 and the fixed frame 100 are only connected by balls, the friction between the movable frame 200 and the fixed frame 100 is extremely low, which helps to improve the service life and quality of use of the telescopic assembly 20.

[0085] As Figures 7 to 9 shown, when the user does not use the functional member 300, the movable frame 200 can be pressed again from below the body 10 to retract the movable frame 200 and the functional member 300 into the body 10 along the sliding direction S2, and the latching portion 230 of the movable frame 200 is engaged with the pushing mechanism 600. In this way, the movable frame 200 and the functional member 300 are fixed in the body 10, and the overall appearance of the electronic device 1 can be improved.

[0086] Please refer to Figure 3 and Figure 10 。 Figure 10 is a plan view of the photographing device 300a of the display device 1a according to the second embodiment of the present invention extending out of the display body 10a.

[0087] The display device 1a of this embodiment includes a display body 10a and a network camera 20a. The display body 10a is, for example, a desktop computer screen. The network camera 20a is, for example, disposed at the central position on the top of the display body 10a. The network camera 20a includes a fixed frame 100a, a movable frame 200a, a photographing device 300a, and a plurality of first balls (such as Figure 3 the first ball 400). The fixed frame 100a is fixed within the display body 10a and has a receiving groove (such as Figure 3 the receiving groove 101) and a plurality of sliding grooves (such as Figure 3 the sliding groove 121). These sliding grooves (such as Figure 3 the sliding groove 121) communicate with the receiving groove (such as Figure 3 the receiving groove 101). The movable frame 200a is movably located in the receiving groove. The photographing device 300a is fixed to the movable frame 200a and is used for photographing or recording images. These first balls (such as Figure 3 the first ball 400) are movably located in these sliding grooves (such as Figure 3 the sliding groove 121), and the movable frame 200a is connected to the fixed frame 100a through these first balls (such as Figure 3 the sliding groove 121). That is to say, the movable frame 200a can drive the photographing device 300a to extend or retract relative to the fixed frame 100a along the sliding directions S1 and S2.

[0088] For the display device, electronic device, and telescopic assembly according to the above embodiment, since the movable frame and the fixed frame are only connected by balls, the friction between the movable frame and the fixed frame is extremely low, which helps to improve the service life and quality of the telescopic assembly.

[0089] In addition, functional components such as network cameras and electrical connectors can extend or retract relative to the body, so as to balance the convenience of use of the functional components and the aesthetics of the overall appearance of the electronic device.

[0090] Although the present invention is disclosed as the foregoing embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be determined by the scope defined in the appended claims.
