Description

electronic devices

[0001] The present invention relates to an electronic device. More specifically, it relates to an electronic device including a hinge member capable of opening to a desired angle and maintaining the open state, so-called "free-stop."

[0002] Hinges are used to open and close laptops and doors. A hinge is a connection that allows mechanical or structural elements to rotate relative to each other.

[0003] Recently, stands capable of supporting electronic devices have been developed. For example, a stand supporting an electronic device includes a hinge assembly capable of rotating a member around a hinge axis. In a folder-type stand, a first member and a second member are connected by a hinge.

[0004] Recently, stands are used for various electronic devices such as webcams installed on monitors and video cameras installed on TVs. However, conventional stands equipped with hinge assemblies that open and close only at a set angle have the disadvantage of not being able to open to the angle desired by the user and opening only at a position set during manufacturing, which does not meet the needs of the user.

[0005] A hinge according to the prior art is a hinge assembly, typically composed of a fixed cap fastened to a housing and a first member, and a movable cam installed inside the housing to be elastically supported by a coil spring and installed to contact the fixed cam, or conversely, a movable cam fastened to the first member and a fixed cam fastened to the second member. In such a hinge assembly according to the prior art, there was an inconvenience in that the stand could only be opened and closed at a set angle because the fixed cam and the movable cam were made to maintain a set angle.

[0006] Meanwhile, in the case of a hinge assembly that can open the stand to a desired angle and has a so-called 'free stop' function, there was a problem in that the structure was complex and there were many assembly components such as bushes and shafts, making the manufacturing process complex and thus increasing the manufacturing cost.

[0007] Stands are opened and closed far less frequently (hundreds of times) than mobile phones or laptops (tens of thousands of times), so they don't require expensive, complex hinges. Therefore, for products like stands with limited opening and closing frequency and simple configurations, a simple, inexpensive "freestop" hinge is needed.

[0008] The present invention aims to solve the above-mentioned problem, and provides an electronic device that can be mounted on various types of display devices with a simple structure and can also be placed on the floor.

[0009] Additionally, it aims to provide an electronic device having a hinge member that is inexpensive and has a simple manufacturing process.

[0010] In addition, it is an object of the present invention to provide an electronic device including a hinge member capable of providing a free stop function with only a simple structure.

[0011] The problems to be solved by the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0018] The parallel pin shape of the above hinge member may be characterized by a 'C' shaped spring pin shape with a slit provided along the longitudinal direction of the hinge member.

[0019] The above fixed part may be characterized in that it has the same diameter as the above rotating part, but the entrance of the slit is formed as a cross-section perpendicular to the direction of the slit.

[0020] It may be characterized in that the length of the above rotating part is longer than the length of the above fixed part.

[0021] The above hinge fixing hole may be a D-hole including a flat portion on one side, and the fixing part may be characterized as a D-cut pin.

[0022] The end of the above fixed part may be characterized by having a circular shape.

[0023] The above first member may further include a front leg positioned protruding on the other side of the inner surface that opens and closes in a folder manner, and the outer height of the front leg may be the same as the outer height of the forming portion of the hinge rotation portion hole.

[0024] The above stand may further include a tripod nut, and the main body may be characterized in that it is coupled with the tripod nut passing through the central hole of the first member.

[0025] It may be characterized in that an anti-rotation protrusion is provided on the back surface of the main body, and an anti-rotation hole is provided on the outer surface of the first member, so that the outer surface of the first member is fastened to the back surface of the main body.

[0026] The above electronic component may be characterized by including a camera module.

[0027]

[0028] An electronic device according to at least one embodiment of the present invention can be easily installed not only on the floor but also on various types of display devices.

[0029] Since the electronic device according to at least one embodiment of the present invention can open the stand to a desired angle and maintain the open state, the electronic device can be used by placing it in a desired location while being opened at an optimal angle.

[0051] Referring to FIG. 1 below, an electronic device (10) according to one embodiment of the present invention will be described.

[0052] FIG. 1 is a drawing showing an electronic device (10) according to one embodiment of the present invention from various angles. FIG. 1 (a) is a perspective view of the electronic device (10), FIG. 1 (b) is a front view of the electronic device (10), and FIG. 1 (c) is a side view of the electronic device (10).

[0053] An electronic device (10) according to one embodiment of the present invention comprises a box-shaped body (100) and a stand (200) supporting the lower portion thereof. Various electronic components may be mounted on the body (100). The electronic device (10) may be a device that provides various functions depending on the electronic components mounted on the body (100). For example, the electronic component may be a camera module. Accordingly, the electronic device (10) may include various types of electronic devices (10), such as a camera, a video camera, a projector, a webcam, and a home cam.

[0054] An electronic device (10) according to one embodiment of the present invention may be equipped with a body (100) having a horizontally elongated shape to collect specific information using multiple cameras and obtain a sense of perspective similar to that of the human eye. If the body (100) is implemented thinly, it has the advantage of not being noticeable when placed on top of a monitor or the like.

[0055] The stand (200) is a device for holding the main body (100). In the case of conventional products, it was mainly in the form of a tong or clamp to be fixed to the top of the monitor, or it had a configuration that allowed for angle adjustment by being placed on a table or attached to the ceiling.

[0056] A stand (200) according to one embodiment of the present invention can be positioned at the lower portion of the main body (100) and support the main body (100). The stand (200) includes a pair of hinges that penetrate the first member (210) and the second member (220), and by adjusting the angle of the pair of hinges, the main body (100) can be placed on the floor or placed on a display device (D). In this case, the display device (D) can be a TV or a monitor, etc. The method by which the stand (200) places the main body (100) will be described later with reference to FIG. 8.

[0057] The stand (200) of the present invention is composed of a first member (210), a second member (220) and a hinge, so that it has a small number of components and can be placed by adjusting the angle with a single movement, thereby increasing user convenience.

[0058] Hereinafter, the configuration of a stand (200) of an electronic device (10) according to an embodiment of the present invention will be described with reference to FIGS. 2 and 3. FIG. 2 is a perspective view showing a stand (200) of an electronic device (10) according to an embodiment of the present invention. FIG. 3 is an exploded perspective view showing the configuration of a stand (200) of an electronic device (10) according to an embodiment of the present invention.

[0059] A stand (200) according to one embodiment of the present invention may include a first member (210) coupled to a main body (100), a second member (220) rotatably coupled to the first member (210), a hinge member (230) penetrating the first member (210) and the second member (220), and a tripod nut (240) coupled to the main body (100) by passing through the central hole of the first member (210).

[0060] The first member (210) may include a front leg (211), an anti-rotation hole (212), a hinge fixing hole (213) provided on one side, a central hole (214), and a second member (220) connecting portion (215). The first member (210) may be connected to the main body (100) and may have a plate shape to support the main body (100). In one embodiment of the present invention, the first member (210) may be the upper plate of the stand (200). Hereinafter, the upper plate refers to the first member (210).

[0061] The second member (220) may include a front leg insertion portion (221), a hinge rotation portion hole forming portion (222), and a hinge rotation portion hole (223). The second member (220) may be rotatably coupled to the first member (210) and may be positioned on the lower side of the first member (210). The first member (210) and the second member (220) may be coupled via a hinge member (230) to be opened and closed in a folder manner. In one embodiment of the present invention, the second member (220) may have a plate shape corresponding to the first member (210) and may be a lower plate of the stand (200). Hereinafter, the lower plate refers to the second member (220).

[0062] The hinge member (230) may include a fixed member (231) coupled to the first member (210) and a rotating member (232) in frictional contact with the second member (220). The fixed member (231) is fixedly coupled to the first member (210), and the rotating member (232) may be coupled to the second member (220) in a force-fit manner to allow for rotational frictional contact.

[0063] Below, the components of the first member (210) are described in detail.

[0064] The front leg (211) of the first member (210) (top plate) is located on the other side (front) of the top plate, and may be positioned so as to protrude on the inner surface that opens and closes in a folder manner, i.e., the lower front of the first member (210). The outer height of the front leg (211), i.e., the outer vertical length, may be the same as the outer height of the forming portion of the hinge rotation portion hole (223). This will be described in detail later with reference to Fig. 8 (b).

[0065] The front leg (211) can contact the upper front surface of the display device (D). The electronic device (10) located on the upper surface of the display device (D) is weighted in the rear direction, and the front leg (211) can be brought into close contact with the upper front surface of the display device (D) by the weight of the electronic device (10) itself (see Fig. 8 (a)).

[0066] As shown in Fig. 2, the front leg (211) can be positioned at a position that does not overlap with the second member (220) when the stand (200) is folded, i.e., at the front leg insertion portion (221), so that the first member (210) and the second member (220) can be in close contact when the stand (200) is folded.

[0067] The anti-rotation hole (212) of the first member (210) may be located on the outer surface, i.e., the upper surface, of the first member (210). The anti-rotation hole may be combined with the anti-rotation protrusion of the main body (100) to serve as a fixing mechanism without shaking when the back surface of the main body (100) and the outer surface of the first member (210) meet and are fastened. This will be described in detail later with reference to FIG. 9.

[0068] The hinge fixing hole (213) of the first member (210) is provided on one side (rear) of the first member (210) and can be fixedly connected to the fixing part (231) of the hinge member (230). That is, the hinge fixing hole (213) is a hole into which the fixing part (231) of the hinge member (230) is inserted. At this time, the inner diameter of the hinge fixing hole (213) may be smaller than the outer diameter of the fixing part (231) of the hinge member (230). The first member (210) and the second member (220) can be opened and closed in a folder manner by being connected by the hinge member (230) penetrating therethrough. This will be described in detail later with reference to FIGS. 4 to 7.

[0069] The central hole of the first member (210) may be a space through which a tripod nut (240) that is located in the central portion of the first member (210) and is coupled with the main body (100) passes. As the tripod nut (240) passes through the central hole and is coupled with the main body (100), the upper plate of the first member (210), i.e., the stand (200), is fixed to the back surface of the main body (100).

[0070] The second member (220) joining portion (215) of the first member (210) may be a space into which a hinge rotation portion hole forming portion (222) is inserted. Since the hinge rotation portion hole forming portion (222) is formed to protrude from the second member (220), a space can be provided for joining without overlapping with the first member (210) so that the hinge member (230) can pass through the first member (210) and the second member (220) in a straight line. It can be formed to correspond to the shape and position of the hinge rotation portion hole forming portion (222).

[0071] The components of the second absence (220) will be described in detail below.

[0072] The front leg insertion portion of the second member (220) may be formed to provide a space in which the front leg (211) of the first member (210) can be positioned when the stand (200) is folded. That is, a space may be provided so that the first member (210) and the second member (220) can be in close contact when the stand (200) is folded, and so that the stand (200) does not overlap with the second member (220) when it is folded. At this time, the front leg insertion portion may correspond to the shape and position of the front leg (211).

[0073] The hinge rotation hole forming portion (222) of the second member (220) can be formed to protrude from one side (rear) of one surface (upper surface) of the second member (220). This is to position the hinge fixing hole (213) of the first member (210) and the hinge rotation hole (223) of the second member (220) in a straight line so that the parallel pin-shaped hinge member (230) can penetrate and connect in a straight line. Therefore, the hinge rotation hole forming portion (222) can be inserted and positioned in the second member (220) connecting portion of the first member (210) during assembly, as shown in FIG. 2.

[0074] The hinge rotation hole (223) of the second member (220) may be formed to protrude in one direction from the second member (220). The hinge rotation hole (223) may be coupled to the rotation part (232) of the hinge member (230) through frictional contact. That is, the hinge rotation hole (223) is a hole into which the rotation part (232) of the hinge member (230) is inserted. The inner diameter of the hinge rotation hole (223) may be smaller than the outer diameter of the rotation part (232) of the hinge member (230). This will be described in detail later with reference to FIGS. 4 to 7.

[0075] The hinge member (230) will be described in detail below.

[0076] The hinge member (230) may include a fixed portion (231) coupled to the first member (210) and a rotating portion (232) in frictional contact with the second member (220). The hinge member (230) according to one embodiment of the present invention may have a parallel pin shape, and the fixed portion (231) may be fixedly coupled and the rotating portion (232) may be coupled in a forced fit manner, thereby providing a 'free stop' function that allows the user to open to a desired angle and maintain that angle.

[0077] The hinge member (230) may be in the shape of a spring pin or a slit pin. This will be described in detail later with reference to the following drawings.

[0078] Hereinafter, with reference to FIGS. 4 and 5, a hinge member (230) according to one embodiment of the present invention and its principle will be described.

[0079] Fig. 4 is a drawing showing a hinge member (230) according to one embodiment of the present invention. Fig. 4 (a) is a perspective view of the hinge member (230), and Fig. 4 (b) is a perspective view showing a state in which a rotation part (232) of the hinge member (230) is fitted into a hinge rotation part hole (223) of a second member (220).

[0080] The hinge member (230) can penetrate the first member (210) and the second member (220) so that the first member (210) and the second member (220) can be opened and closed in a folder manner. That is, by penetrating one side of the first member (210) and one side of the second member (220) and joining them in a fitting manner, the first member (210) and the second member (220) can be joined and the other side can be opened and closed in a folder manner.

[0081] A hinge member (230) according to one embodiment of the present invention may include a fixed portion (231), a rotating portion (232), and a joint (233) between the fixed portion (231) and the rotating portion (232). The hinge member (230) may have a parallel pin shape. The parallel pin shape refers to a pin shape in which all diameters are the same. The hinge member (230) has a parallel pin shape as a whole, but in one embodiment of the present invention, it may be applied with some modifications.

[0082] The fixed part (231) can be fitted into the first member (210) and the rotating part (232) can be fitted into the second member (220). That is, the fixed part (231) can be coupled to the hinge fixing part hole (213) of the first member (210), and the rotating part (232) can be coupled to the hinge rotating part hole (223) of the second member (220). The fixed part (231) can be press-fitted into the hinge fixing part hole (213) of the first member (210) in a force-fit manner. The rotating part (232) can also be press-fitted into the hinge rotating part hole (223) of the second member (220) in a force-fit manner. Therefore, the inner diameter of the hinge rotating part hole (223) is required to be smaller than the outer diameter of the rotating part (232).

[0083] Referring to FIGS. 4 (a) and 5 (a), the hinge member (230) according to one embodiment of the present invention has an overall parallel pin shape, and the rotating portion (232) may have a slit pin shape with a bifurcated shape. In addition, the fixed portion (231) may have a D-cut pin shape including a flat portion on one side. In this case, the end of the fixed portion (231) may have a circular pin shape. In this case, the length of the rotating portion (232) may be shorter than the length of the fixed portion (231). This will be described in more detail below.

[0084] According to one embodiment of the present invention, the rotational member (232) of the hinge member (230) may have a slit pin shape. For example, the slit of the rotational member (232) may be located at the center of the pin and formed in the longitudinal direction of the pin. That is, the rotational member (232) may have a slit pin shape that is split into two.

[0085] At this time, the rotating part (232) may have a smaller diameter than the fixed part (231). This is to increase convenience in the process, as when the hinge member (230) is pressed in during the hinge assembly process, the rotating part (232) can pass through the hinge fixing part hole (213) and be pressed into the hinge rotating part hole (223).

[0086] Meanwhile, the joint connecting the fixed part (231) and the rotating part (232) may have a smaller diameter than the rotating part (232). This is to enable the fixed part (231) to bend inward more easily when force is applied toward the slit during the press-fitting process to forcefully fit it into the hinge rotating part hole (223).

[0087] According to one embodiment of the present invention, the fixing member (231) of the hinge member (230) may have a D-cut pin shape. That is, it may have a shape that includes a flat portion on one side. This is because the fixing member (231) does not independently rotate in the circumferential direction but must move together with the hinge fixing member hole (213) by combining with the hinge fixing member hole (213), so that it may be fixed to the hinge fixing member hole (213) by adding a flat shape. Accordingly, the hinge fixing member hole (213) may also be a D-hole that includes a flat portion on one side.

[0088] Meanwhile, although the overall shape of the fixing part (231) is a D-cut pin shape, the end of the fixing part (231) may again have a circular pin shape. Since the end of the fixing part (231) is a part that is exposed to the outer surface of the product, it may be finished in a circular shape for aesthetic purposes and to improve the completeness of the product.

[0089] According to one embodiment of the present invention, in the hinge member (230), when the rotating part (232) has a slit pin shape, the length of the rotating part (232) may be shorter than the length of the fixed part (231). That is, the fixed part (231) may be longer than the rotating part (232). For example, the length ratio of the rotating part (232) and the fixed part (231) may be 4:5. This is because, in the case of the slit pin, the rotating part (232) is a part where torque due to friction is generated and may be easily deformed during use. Therefore, the length of the rotating part (232) is shortened to increase reliability and the length of the fixed part (231) is lengthened to stably fix the mechanism.

[0090] Referring to Fig. 4 (b), the rotation part (232) of the hinge member (230) can be press-fitted into the hinge rotation part hole (223) of the second member (220). The hinge rotation part hole (223) can be formed by protruding one side of the second member (220) to form the hinge rotation part hole forming part (222). The fixing part (231) can be fixedly coupled to the hinge fixing part hole (213). Since the press-fitted rotation part (232) rotates while generating torque due to frictional force, the first member (210) and the second member (220) can be opened and closed by an angle desired by the user. The principle will be described in detail with reference to the following Fig. 5.

[0091] FIG. 5 is a drawing for explaining the principle of a hinge according to one embodiment of the present invention. FIG. 5 (a) is a side view showing the side of a hinge member (230). FIG. 5 (b) is a perspective view for explaining the principle of providing a free-stop function using frictional force when the hinge member (230) is fitted into a hole.

[0092] Referring to FIG. 5 (a), a hinge member (230) according to one embodiment of the present invention may include a fixed portion (231), a rotating portion (232), and a joint (233) between the fixed portion (231) and the rotating portion (232). As described above in FIG. 4, the rotating portion (232) may have a slit pin shape with a bifurcated shape. In addition, the fixed portion (231) may have a D-cut pin shape including a flat portion on one side. In this case, the end of the fixed portion (231) may have a circular pin shape. In addition, the length of the rotating portion (232) may be shorter than the length of the fixed portion (231).

[0093] Referring to the perspective view of Fig. 5 (b), the fixed part (231) of the hinge member (230) according to one embodiment of the present invention may be fixedly coupled to the hinge fixed part hole (213), and the rotating part (232) may be coupled to the hinge rotating part hole (223) through frictional contact (f).

[0094] According to one embodiment of the present invention, the fixed portion (231) of the hinge member (230) forms a certain angle and is fixedly connected to the first member (210), so that when a user rotates the hinge, it does not rotate independently but is fixed to the first member (210) and rotates together. On the other hand, the rotating portion (232) of the hinge member (230) is in frictional contact and rotates separately from the second member (220) when the user applies a force of a predetermined size or more.

[0095] In other words, when assembling the hinge member (230) to the first member (210) and the second member (220), the rotating member (232) is press-fitted into the hinge rotating member hole (223) with the slit portion being banded, which has an inner diameter smaller than the outer diameter of the rotating member (232), so that after joining, a force (F) that continuously pushes outward is applied to the inside of the hole due to the elastic force of the slit portion of the rotating member (232), and thus, the outer surface of the rotating member (232) and the inner surface of the hinge rotating member hole (223) come into frictional contact (f).

[0096] Accordingly, the hinge member (230) of the stand (200) has a frictional force (f) and rotates only when a force greater than a predetermined size (a force greater than the frictional force) is applied. Due to this characteristic, the stand (200) can be opened to any angle desired by the user, and a so-called 'free stop' function can be provided to maintain the stand in the open state.

[0097] Conventional hinges providing a free-stop function are hinge assemblies that typically require multiple parts, which complicates the manufacturing process and increases the unit cost even when applied to simple mechanisms. The hinge member (230) according to one embodiment of the present invention is directly assembled to the first member (210) and the second member (220) with a single pin capable of providing a free-stop function, thereby significantly simplifying the assembly step and facilitating the manufacturing process, thereby significantly reducing the manufacturing cost. In addition, since the number of parts is small, maintenance and repair are convenient, which can increase the reliability of the product.

[0098] Hereinafter, a hinge member (230) and its principle according to another embodiment of the present invention will be described with reference to FIGS. 6 and 7.

[0099] Fig. 6 is a drawing showing a hinge member (230) according to another embodiment of the present invention. Fig. 6 (a) is a perspective view of the hinge member (230), and Fig. 6 (b) is a perspective view showing a state in which a rotation part (232) of the hinge member (230) is fitted into a hinge rotation part hole (223) of a second member (220).

[0100] As described above, the hinge member (230) can penetrate the first member (210) and the second member (220) so that the first member (210) and the second member (220) can be opened and closed in a folder manner. That is, by penetrating one side of the first member (210) and one side of the second member (220) and joining them in a fitting manner, the first member (210) and the second member (220) can be joined and the other side can be opened and closed in a folder manner.

[0101] According to another embodiment of the present invention, a hinge member (230) may include a fixed portion (231) and a rotating portion (232). The hinge member (230) may have a parallel pin shape. The parallel pin shape refers to a pin shape in which all parts have the same diameter. The hinge member (230) has a parallel pin shape as a whole, but in one embodiment of the present invention, it may be applied with some modifications.

[0102] As described above, the fixed part (231) can be fitted to the first member (210) and the rotating part (232) can be fitted to the second member (220). That is, the fixed part (231) can be coupled to the hinge fixing part hole (213) of the first member (210), and the rotating part (232) can be coupled to the hinge rotating part hole (223) of the second member (220). The fixed part (231) can be press-fitted into the hinge fixing part hole (213) of the first member (210) in a force-fit manner. The rotating part (232) can also be press-fitted into the hinge rotating part hole (223) of the second member (220) in a force-fit manner. Therefore, the inner diameter of the hinge rotating part hole (223) is required to be smaller than the outer diameter of the rotating part (232).

[0103] Referring to FIGS. 6 and 7 (a), a hinge member (230) according to another embodiment of the present invention may have an overall parallel pin shape and may be a 'C'-shaped spring pin shape with a slit provided along the longitudinal direction of the hinge member (230). At this time, the fixed portion (231) may have the same diameter as the rotating portion (232), but the entrance of the slit may be formed as a cross-section perpendicular to the direction of the slit. At this time, the length of the rotating portion (232) may be longer than the length of the fixed portion (231). This will be described in more detail below.

[0104] According to another embodiment of the present invention, a hinge member (230) may be a spring pin having a cross-section perpendicular to the longitudinal direction and having a 'C' shape. A spring pin is a pin that is made by heat-treating a thin plate and rolling it into a cylindrical shape. When installed in a hole, it adheres to the inside of the hole by the spring action, thereby generating a high holding force. That is, when it is pressed into the hole in a forced fit manner, it adheres to the inside of the hole by the elastic force that tries to return to its original state. The hinge member (230) of the present invention may have a shape of a spring pin, and is not limited to the manufacturing method described above, and the pin in the shape of a spring pin may be manufactured from a metal or plastic material.

[0105] The fixed part (231) may have the same diameter and slit as the rotating part (232), but may have a slit entrance that is cut out compared to the rotating part (232). At this time, the cut surface may be formed in a direction perpendicular to the direction of the slit. That is, if both ends of the C shape of the cross section of the rotating part (232) are extended and connected, an O shape may be formed, and if both ends of the C shape of the cross section of the fixed part (231) are connected, a D shape may be formed.

[0106] According to another embodiment of the present invention, the fixing member (231) has a truncated C shape, i.e., a D shape without a straight portion, and thus can have the same effect as the D-cut pin-shaped fixing member (231) of the above-described embodiment of the present invention. That is, by forming an angle, the fixing member (231) does not rotate independently in the circumferential direction, but can move together with the first member (210) by engaging with the hinge fixing member hole (213). Accordingly, the hinge fixing member hole (213) may also be a D-hole including a flat portion on one side.

[0107] Meanwhile, in the case where the hinge member (230) according to another embodiment of the present invention has a spring pin shape, the length of the rotating part (232) may be longer than the length of the fixed part (231). That is, the fixed part (231) may be shorter than the rotating part (232). For example, the length ratio of the rotating part (232) and the fixed part (231) may be 5:4. This is because, in the case of a spring pin, unlike a slit pin, the entire shaft is prone to deformation when used, so the length of the rotating part (232) where torque is generated is made longer to reduce the possibility of deformation and increase reliability.

[0108] Referring to Fig. 6 (b), the rotation part (232) of the hinge member (230) can be press-fitted into the hinge rotation part hole (223) of the second member (220). The hinge rotation part hole (223) can be formed by protruding one side of the second member (220) to form the hinge rotation part hole forming part (222). The fixing part (231) can be fixedly coupled to the hinge fixing part hole (213). Since the press-fitted rotation part (232) rotates while generating torque due to frictional force, the first member (210) and the second member (220) can be opened and closed by an angle desired by the user. The principle will be described in detail with reference to the following Fig. 7.

[0109] FIG. 7 is a drawing for explaining the principle of a hinge according to another embodiment of the present invention. FIG. 7 (a) is a side view showing the side of a hinge member (230). FIG. 7 (b) is a perspective view for explaining the principle of providing a free-stop function using frictional force when the hinge member (230) is fitted into a hole.

[0110] Referring to Fig. 7 (a), a hinge member (230) according to another embodiment of the present invention may include a fixed portion (231) and a rotating portion (232). As described above in Fig. 6, the hinge member (230) may have an overall parallel pin shape and may be a 'C'-shaped spring pin shape with a slit provided along the longitudinal direction of the hinge member (230). At this time, the fixed portion (231) may have the same diameter as the rotating portion (232), but the entrance of the slit may be formed as a cross-section perpendicular to the direction of the slit. At this time, the length of the rotating portion (232) may be longer than the length of the fixed portion (231).

[0111] Referring to the perspective view of Fig. 7 (b), the fixed part (231) of the hinge member (230) according to one embodiment of the present invention is fixedly coupled to the hinge fixed part hole (213), and the rotating part (232) may be coupled to the hinge rotating part hole (223) through frictional contact (f).

[0112] According to one embodiment of the present invention, the fixed portion (231) of the hinge member (230) forms a certain angle and is fixedly connected to the first member (210), so that when a user rotates the hinge, it does not rotate independently but is fixed to the first member (210) and rotates together. On the other hand, the rotating portion (232) of the hinge member (230) is in frictional contact and rotates separately from the second member (220) when the user applies a force of a predetermined size or more.

[0113] In other words, when assembling the hinge member (230) to the first member (210) and the second member (220), the rotating member (232) is press-fitted into the hinge rotating member hole (223) having an inner diameter smaller than the outer diameter of the rotating member (232) in a spring pin shape, so that after joining, a force (F) that continuously pushes outward is applied to the inside of the hole by the elastic restoring force of the rotating member (232), and thus, the outer surface of the rotating member (232) and the inner surface of the hinge rotating member hole (223) come into frictional contact (f).

[0114] Accordingly, the hinge member (230) of the stand (200) has a frictional force (f) and rotates only when a force greater than a predetermined size (a force greater than the frictional force) is applied. Due to this characteristic, the stand (200) can be opened to any angle desired by the user, and a so-called 'free stop' function can be provided to maintain the stand in the open state.

[0115] Conventional hinges providing a free-stop function are hinge assemblies that typically require multiple parts, which complicates the manufacturing process and increases the unit cost even when applied to simple mechanisms. The hinge member (230) according to one embodiment of the present invention is directly assembled to the first member (210) and the second member (220) with a single pin capable of providing a free-stop function, thereby significantly simplifying the assembly step and facilitating the manufacturing process, thereby significantly reducing the manufacturing cost. In addition, since the number of parts is small, maintenance and repair are convenient, which can increase the reliability of the product.

[0116] Fig. 8 is a drawing showing an example of a mounting method of an electronic device (10) according to one embodiment of the present invention. Fig. 8 (a) shows a side view of an electronic device (10) mounted on the top of a display device (D), and Fig. 8 (b) shows a side view of an electronic device (10) mounted on the floor.

[0117] Referring to FIG. 8 (a), the first member (210) (top plate) (210) of the stand (200) is positioned at the lower portion of the main body (100) to support the main body (100) and can be mounted on the upper portion of the display device (D). The stand (200) according to one embodiment of the present invention can adjust the angle of the first member (210) and the second member (220) through a hinge, thereby changing the shape of the stand (200) at various angles.

[0118] As shown in Fig. 8 (a), a stand (200) according to one embodiment of the present invention may include a front leg (211) positioned at the lower front of a first member (210), and the front leg (211) contacts the upper front surface of a display device (D). The main body (100) positioned at the upper portion of the display device (D) is weighted in the rear direction, and the front leg (211) can be brought into close contact with the upper front surface of the display by the weight of the main body (100) itself.

[0119] Meanwhile, the end of the second member (220) can touch the back surface of the display device (D) and support the weight of the main body (100). This structure has the advantage of being able to be mounted on display devices (D) of various shapes. It can be mounted on thin display devices, display devices including an inclined surface on the back surface, and thick display devices.

[0120] At this time, the user can open the stand (200) to the required angle and place it on the display device (D), and as described above, the hinge (230) of the stand (200) maintains the open angle due to frictional force, so the angle does not change when placed. That is, the hinge has frictional force, so the angle changes only when a force greater than a certain amount is applied, and since the weight of the main body (100) is only a few hundred grams, the angle will not change due to the weight of the main body (100), so it can be stably placed on the top of the display device (D). At this time, the stand (200) can be manufactured from a plastic material for light weight and convenience of process.

[0121] As shown in Fig. 8 (b), the first member (210) and the second member (220) can be configured to have the same thickness, and when folded so that the angle between the first member (210) and the second member (220) becomes 0°, the thickness of the stand (200) can be minimized. At this time, the hinge can form a 90° angle. As described above in Fig. 2, the front leg (211) can be positioned at a position that does not overlap with the second member (220) when the stand (200) is folded, i.e., at the front leg insertion portion (221), so that the first member (210) and the second member (220) can be in close contact with each other when the stand (200) is folded.

[0122] At this time, the outer height of the front leg (211) and the outer length of the hinge rotation hole forming portion (222) may be the same. When the stand (200) is placed on the floor in a folded state, the front leg (211) of the first member (210) and the hinge rotation hole forming portion (222) of the second member (220) connected to the first member (210) serve as columns supporting the first member (210), so that the heights of each component must be the same to enable folding parallel to the second member (220). This is to ensure stable use of the electronic device (10) when placed on a flat floor.

[0123] Accordingly, as shown in Fig. 8 (b), when the stand (200) is folded, the first member (210) and the second member (220) can be arranged parallel to the bottom surface of the main body (100) and can be stably placed on the bottom surface.

[0124] An electronic device (10) according to one embodiment of the present invention includes a stand (200) that can be placed on the top of a display device (D) as well as on the floor, with only a small number of components, thereby increasing convenience when using the electronic device (10), and simplifying the manufacturing process, thereby providing a highly reliable product at a low price.

[0125] Fig. 9 is a drawing for explaining a rotation prevention means of an electronic device (10) according to one embodiment of the present invention. It is a perspective view showing the upper surface of the stand (200) and the rear surface of the main body (100) as the upper surfaces, respectively.

[0126] An electronic device (10) according to one embodiment of the present invention may include a main body (100) on which electronic components are mounted, and a stand (200). The main body (100) may include anti-rotation protrusions (112a, 112b) on a rear surface coupled with the stand (200). The stand (200) may include a first member (210), and the first member (210) may include anti-rotation holes (212a, 212b) on an outer surface.

[0127] The stand (200) is located at the lower part of the main body (100) and supports the main body (100). When combined with the main body (100), the back surface of the main body (100) and the upper surface of the first member (210) (top plate) come into contact. At this time, the rotation prevention protrusion on the back surface of the main body (100) and the rotation prevention hole on the outer surface of the first member (210) are connected to prevent the rotation of the main body (100) when the main body (100) and the stand (200) are combined, and the main body (100) is maintained in a firmly coupled state without shaking.

[0128] According to one embodiment of the present invention, the anti-rotation hole may be provided in the shape of a groove partially dug in the central hole (212a). According to another embodiment, the anti-rotation holes may be respectively positioned at the front corners of the upper surface of the first member (210) (212b). The anti-rotation protrusion of the main body (100) may have a shape and position corresponding to the anti-rotation hole. As shown in Fig. 9, the anti-rotation means may be arranged in a triangular shape to further enhance stability.

[0129] It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

[0130] The above detailed description should not be construed as limiting in any respect and should be considered illustrative only. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are intended to be included within the scope of the present invention.
