[0026] Please first refer to Figure 1 , Figure 2 and Figure 6 , in this embodiment, the support frame 100 is adapted to support the electronic body 10. The support frame 100 includes a movable member 110, an elastic member 120, and a limiting member 130. The movable member 110 includes a body 112 and a cam structure 114. The cam structure 114 is located at one end portion 113 of the body 112, and the end portion 113 is pivotally connected to the electronic body 10 based on a pivot 140 and is located inside the electronic body 10. The cam structure 114 includes a first convex portion 115 and a second convex portion 117 disposed around the pivot 140. The elastic member 120 is disposed inside the electronic body 10 and includes a plurality of elastic pieces separated from each other (schematically shown as three elastic pieces 122, 124, and 126). The limiting member 130 is disposed inside the electronic body 10 and includes a plurality of pins separated from each other and arranged along an axis direction L of the pivot 140 (schematically shown as three pins 132, 134, and 136). The pins 132, 134, and 136 are respectively located on the elastic pieces 122, 124, and 126, wherein the rotational resistance of the movable member 110 relative to the electronic body 10 when the pins 132, 134, and 136 slidably abut against the first convex portion 115 is different from the rotational resistance of the movable member 110 relative to the electronic body 10 when the pins 132, 134, and 136 slidably abut against the second convex portion 117.

[0027] Specifically, the electronic body 10 may be, for example, a display, a tablet, a mobile phone, or a handwriting board screen, but is not limited thereto, and the support frame 100 is assembled on the electronic body 10 to support the electronic body 10. Furthermore, the pivot 140 is connected to the electronic body 10 and passes through one end portion 113 of the movable member 110, wherein the movable member 110 rotates relative to the electronic body 10 with the pivot 140 as the axis. Herein, the movable member 110 is, for example, a tripod, which can support the electronic body 10 to stand when opened.

[0028] Next, a cam is a member having a curved profile or groove. Please also refer to Figure 2 and Figure 5 , the cam structure 114 of the movable member 110 in this embodiment includes a first convex portion 115 and a second convex portion 117. The first convex portion 115 and the second convex portion 117 are respectively located on different axial sections. Viewed in cross-section, the profile of the first convex portion 115 is different from the profile of the second convex portion 117. In one embodiment, the cross-sectional profile of the first convex portion 115 is, for example, approximately rectangular, and the cross-sectional profile of the second convex portion 117 is, for example, approximately triangular, but is not limited thereto.

[0029] Specifically, the first protrusion 115 includes a first sub-protrusion 115a and two second sub-protrusions 115b arranged side by side along the axial direction L of the pivot shaft 140. The first sub-protrusion 115a is located between the second sub-protrusions 115b, and the first sub-protrusion 115a has a radial length difference relative to each second sub-protrusion 115b. Figure 5 As shown, the first radial length H1 of the first sub-protrusion 115a is greater than the second radial length H2 of each second sub-protrusion 115b. Here, the first radial length H1 refers to the radial dimension (distance) of the highest point of the first sub-protrusion 115a relative to the axis of the pivot 140, and the second radial length H2 refers to the radial dimension (distance) of the highest point of the second sub-protrusion 115b relative to the axis of the pivot 140. That is, at the same axial cross section, the radial dimensions of the first sub-protrusion 115a and the second sub-protrusion 115b are different, that is, there is a radial dimension difference between the two.

[0030] In addition, please also refer to Figure 4 , Figure 5 , Figure 7 and Figure 8 The cam structure 114 of this embodiment also includes a first recessed portion 118 and a second recessed portion 119. The first recessed portion 118 is disposed adjacent to the first convex portion 115 and has a smooth transition, while the second recessed portion 119 is disposed adjacent to the second convex portion 117 and has a smooth transition. The so-called smooth transition means that the adjacent convex portions and recessed portions are cotangent at the connection, or it can also be understood that the curvature at the connection is the same, so that when the elastic member is slidably abutted, it can smoothly and without jamming transition from one part to another. In other words, in cross-section, the first recessed portion 118 and the first convex portion 115 present a continuous curved profile, while the second recessed portion 119 and the second convex portion 117 present a continuous curved profile.

[0031] In one embodiment, the cam structure may be a disc cam, which means that the cam is a disc-shaped component that rotates around a fixed axis and has a variable radius, but the present invention is not limited thereto. In another embodiment, the cam structure may be a moving cam, which means that the cam moves linearly relative to the frame, and the cam structure is connected to the body in a transmission manner, but the present invention is not limited thereto. In another embodiment, the cam structure may be a cylindrical cam, which means that the cam is a cylinder, and the moving cam may be considered to be rolled into a cylinder, but the present invention is not limited thereto.

[0032] Please refer to Figure 1, the elastic pieces 122, 124, 126 of the elastic member 120 in this embodiment include a first elastic piece 122 and two second elastic pieces 124, 126, wherein the first elastic piece 122 is located between the second elastic pieces 124, 126. Furthermore, the elastic member 120 further includes a connecting portion 125, and the connecting portion 125 connects the first elastic piece 122 with the second elastic pieces 124, 126. In one embodiment, the first elastic piece 122, the second elastic pieces 124, 126, and the connecting portion 125 may be an integrally formed structure. In one embodiment, the first elastic piece 122, the second elastic pieces 124, 126, and the connecting portion 125 may be in a comb-like structure. That is to say, there is a gap between the first elastic piece 122 and the second elastic pieces 124, 126, and the first elastic piece 122 and the second elastic pieces 124, 126 are respectively in a strip or long strip structure, and the first elastic piece 122 and the second elastic pieces 124, 126 are connected by the connecting portion 125 to form a comb-like structure. In one embodiment, the material of the elastic member 120 may be, for example, metal, alloy, plastic, silica gel, or rubber, but is not limited thereto.

[0033] Please refer to again Figure 6 , the pins 132, 134, 136 of this embodiment include a first pin 132 and two second pins 134, 136. The first pin 132 is disposed on the first elastic piece 122 and is located between the first elastic piece 122 and the cam structure 114. The second pin 134 is located on the second elastic piece 124 and is located between the second elastic piece 124 and the cam structure 114. The second pin 136 is located on the second elastic piece 126 and is located between the second elastic piece 126 and the cam structure 114. The first pin 132 and the second pins 134, 136 are respectively fixed to the first elastic piece 122 and the second elastic pieces 124, 126, and the fixing methods include pasting, magnetic attraction, locking, or other appropriate methods.

[0034] In one embodiment, the first pin 132 and the second pins 134, 136 may be respectively in a triangular pyramid structure, but are not limited thereto. In one embodiment, the first pin 132 and the second pins 134, 136 may each be composed of a flat plate portion and an interference portion connecting the flat plate portion, wherein the interference portion may protrude relative to the flat plate portion, and the flat plate portion and the interference portion may be an integrally formed structure, but are not limited thereto. In one embodiment, the materials of the first pin 132 and the second pins 134, 136 may include plastic, silica gel, rubber, or magnetic material, but are not limited thereto.

[0035] Generally speaking, when the support frame 100 is in the closed state, only a relatively small force is required to maintain the closure; while, in the open state, a relatively large force is required to avoid automatic closure. In addition, the support frame 100 also needs to be designed by a mechanism so that the movable member 110 can be fixed at a specific position in the closed or open state, thereby achieving the purpose of small volume and low cost.

[0036] Please also refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 . When the first bolt 132 and the second bolts 134, 136 are respectively slidably abutted against the first sub-convex portion 115a and the second sub-convex portion 115b of the cam structure 114 and are located within the first recess 118, the movable member 110 rotates relative to the electronic body 10 to a closed position P1 with a first force. Next, please also refer to Figure 3 , Figure 7 , Figure 8 and Figure 9 . When the first bolt 132 and the second bolts 134, 136 abut against the second convex portion 117 of the cam structure 114 and are located within the second recess 119, the movable member 110 rotates relative to the electronic body 10 to an open position P2 with a second force. In one embodiment, the coefficient of friction between the first sub-convex portion 115a of the first convex portion 115 and the first bolt 132 is, for example, less than the coefficient of friction between the second convex portion 117 and the first bolt 132. That is to say, the second force is, for example, greater than the first force.

[0037] In other words, the middle first elastic piece 122 is paired with the first sub-convex portion 115a of the first convex portion 115 in the cam structure 114 having a relatively high height, while the second elastic pieces 124, 126 on both sides are paired with the second sub-convex portion 115b of the first convex portion 115 in the cam structure 114 having a relatively low height, which can provide a relatively small closing state force. On the other hand, the middle first elastic piece 122 and the second elastic pieces 124, 126 on both sides are simultaneously paired with the second convex portion 117 in the cam structure 114, which can provide a relatively large opening state force. With this design, it is more labor-saving for the movable member 110 to switch from the closed state to the open state, and it is more stable when maintaining the open state. In short, the support frame 100 of this embodiment can distinguish different elastic forces applied for closing or opening through the structural arrangement, so that it does not require much force to switch from the closed state to the open state, and it is not too easy to be closed again when switching from the closed state to the open state, which can achieve the purpose of improving safety and user experience.

[0038] It is worth mentioning that when there is enough space, the elastic member 120 can also be designed to be like the comb in a music box, having more than three elastic pieces (such as four elastic pieces or more), and by being paired with the cam structure 114 of the movable member 110, it is set to have three segments, four segments or more segments of force, which is not limited herein.

[0039] For example, in an embodiment (not shown), the second convex portion may also have a structure similar to that of the first convex portion. That is, the second convex portion may include a third sub-convex portion and two fourth sub-convex portions arranged along the axial direction of the pivot axis, where the third sub-convex portion is located between the two fourth sub-convex portions. The radial dimension of the third sub-convex portion may be greater than the radial dimension of the fourth sub-convex portion, so that the abutting force between the two side sub-convex portions and the plug is slightly smaller, facilitating the smooth and non-sticking sliding transition of the elastic piece. The radial dimension of the first sub-convex portion may be smaller than the radial dimension of the third sub-convex portion, and the radial dimension of the second sub-convex portion may be smaller than the radial dimension of the fourth sub-convex portion. The third sub-convex portion may correspond to the first elastic piece, and the two fourth sub-convex portions correspond to the two second elastic pieces. In this way, the rotational resistance when the plug abuts against the first convex portion is less than the rotational resistance when the plug abuts against the second convex portion. In an embodiment, the first radial dimension difference between the first sub-convex portion and the second sub-convex portion is different from the second radial dimension difference between the third sub-convex portion and the fourth sub-convex portion, so as to ensure that the elastic piece can slide smoothly and without jamming through the two side sub-convex portions, and adjust the rotational resistance through the middle sub-convex portion. For example, Figure 9 In [reference number], the second convex portion 117 is equivalent to a special case where the second radial dimension difference between the third sub-convex portion and the fourth sub-convex portion is zero. In another embodiment, the friction coefficient between the first sub-convex portion and the first plug is less than the friction coefficient between the third sub-convex portion and the first plug.

[0040] In an embodiment, the opening and closing forces can also be designed by changing the height of the first convex portion 115 and the second convex portion 117 of the cam structure 114, or the slopes of the first convex portion 115 and the second convex portion 117, or the depth of the groove formed between multiple protruding portions (such as the first convex portion 115 and the second convex portion 117) of the cam structure 114. In an embodiment, the movable member 110 can be fixed at the closed position P1 or the open position P2, for example, by the first plug 132 and the second plugs 134, 136 being fixable in different recesses, where the recesses can be, for example, different-depth recesses formed between multiple protruding portions of the cam structure, but not limited thereto. In an embodiment, the angle between the two recesses can be, for example, approximately 90 degrees, but not limited thereto.

[0041] In summary, in the design of the support frame of the present invention, the elastic member includes multiple elastic pieces separated from each other, and the plugs of the limiting member are respectively located on the elastic pieces, where the rotational resistance of the movable member relative to the electronic body when the plug slidably abuts against the first convex portion is different from the rotational resistance of the movable member relative to the electronic body when the plug slidably abuts against the second convex portion. Therefore, the support frame of the present invention does not require much force to switch from closed to open, and is not too likely to be closed again when switching from closed to open, which can improve safety and enhance the user experience.

[0042] The present invention has been described by the above related embodiments. However, the above embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and refinements made without departing from the spirit and scope of the present invention fall within the scope of patent protection of the present invention.
