Description

Technical Field

[0001] The present application relates to the field of mechanics, and in particular to an elastic member, a hinge assembly and a terminal product. Background Art

[0002] Cylindrical springs are often used in mechanical structures to achieve elastic effects. Cylindrical springs usually need to be used in conjunction with a central shaft that passes through the cylindrical spring to limit the position of the cylindrical spring when it is deformed. Space for matching clearance and deformation avoidance needs to be reserved between the circular spring and the central shaft. In addition, the rigidity of the cylindrical spring is difficult to increase due to the limitation of the matching space. If the number of cylindrical springs is increased, the installation volume of the cylindrical spring will increase accordingly. In addition, there is a risk of the central shaft breaking. Summary of the invention

[0004] In the above design, the elastic part between the first beam part and the second beam part undergoes elastic deformation, so that the elastic part has a damping effect. Among them, when the elastic part is applied to the hinge assembly or the terminal product, it can be used alone, that is, it replaces the technical solution of using a cylindrical spring in combination with a central axis in the related art, that is, the elastic part provided in the embodiment of the present application does not need to reserve the installation space required for the central axis, nor does it need to reserve the matching clearance between the cylindrical spring and the central axis in the related art; and there is no risk of the central axis breaking; when the elastic part in the present application is applied to the hinge assembly or the terminal product, it can have a variety of assembly methods to increase the scope of application of the elastic part; when the elastic parts of the present application are used in a superimposed manner, the installation space of the elastic part will not be significantly increased.

[0014] In some possible implementations of the present application, the angle ranges from 30° to 120°.

[0015] The above design is beneficial for ensuring the deformation space of the elastic member and for the elastic member to have a suitable stiffness coefficient.

[0016] In some possible embodiments of the present application, the first beam portion includes a first supporting surface, which is located at an end of the first beam portion away from the elastic portion; the second beam portion includes a second supporting surface, which is located at an end of the second beam portion away from the elastic portion; the first supporting surface and the second supporting surface are parallel to each other.

[0021] The two second beam portions in at least two elastic units are connected to each other;

[0023] In some possible implementations of the present application, the elastic member further includes a connecting portion, which connects two adjacent elastic units; the connecting portion is used to generate elastic deformation under a force.

[0031] In the above design, when the force is applied to the elastic part through the middle section, the two sides of the elastic part located on the outside produce elastic deformation outward, and the two sides of the elastic part located on the inside produce elastic deformation inward, so the areas where elastic deformation occurs between the two connected elastic parts will not interfere with each other.

[0069] DETAILED DESCRIPTION

[0070] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth to facilitate a full understanding of the present application, and the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0071] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this article are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes all and any combination of one or more related listed items.

[0072] In the embodiments of the present application, for the convenience of description and not to limit the present application, the term "connection" used in the patent application specification and claims of the present application is not limited to physical or mechanical connection, whether direct or indirect. "Up", "down", "above", "below", "left", "right", etc. are only used to indicate relative position relationship. When the absolute position of the described object changes, the relative position relationship also changes accordingly.

[0073] See also Figure 1 The embodiment of the present application provides a terminal product 200, which may be a product including the hinge assembly 100. The terminal product 200 may be an electronic product, including but not limited to a laptop computer, a tablet computer, a folding screen mobile phone, a camera, a drone, a desk lamp, a laptop computer accessory, a tablet computer accessory, a mobile phone accessory, etc.; the terminal product 200 may also be a non-electronic product, including but not limited to a door, a Bluetooth headset box, a glasses box, a folding chair, etc.

[0074] In this embodiment, the terminal product 200 is a folding screen mobile phone as an example for description. The terminal product 200 also includes a first body 210 and a second body 220, and the hinge assembly 100 connects the first body 210 and the second body 220. The hinge assembly 100 can change the opening and closing angle of the first body 210 and the second body 220, and can also keep the first body 210 and the second body 220 at the opening and closing angle required by the user.

[0075] The specific structures of the first body 210 and the second body 220 are related to the application scenario of the hinge assembly 100. For example, when the terminal product 200 is a laptop computer, the first body 210 may be the part where the keyboard is located, and the second body 220 may be the part where the display screen is located; when the terminal product 200 is a folding screen mobile phone, the first body 210 and the second body 220 are both the parts where the screen is located; when the terminal product 200 is a door, the first body 210 may be a door frame, and the second body 220 may be a door panel. The above is only for illustration and is not intended to be limiting.

[0076] The first body 210 and the second body 220 can be flattened or folded to meet the usage requirements in different scenarios. The first body 210 and the second body 220 can be folded in the length direction of the folding screen mobile phone, or in the width direction of the folding screen mobile phone. For example, the angle between the first body 210 and the second body 220 is 180°, so that the folding screen mobile phone can achieve a large screen display; the angle between the first body 210 and the second body 220 is an obtuse angle, and the folding screen mobile phone can be placed on the desktop in an upright state while achieving the larger screen display requirements; when the angle between the first body 210 and the second body 220 is 0°, the folding screen mobile phone is in a closed state, so that the folding screen mobile phone has a smaller volume for easy carrying. The above-mentioned usage status is only for illustration and is not limited thereto.

[0077] See also Figures 2 to 5 , Figure 2 This is a schematic diagram of the structure of the hinge assembly 100 provided in an embodiment of the present application. Figure 3 An exploded view of the hinge assembly 100 provided in an embodiment of the present application, Figure 4 for Figure 2 The cross-sectional view of the hinge assembly 100 along the AA direction is shown. Figure 5 for Figure 2 The shown diagram is a cross-sectional view of the hinge assembly 100 along the BB direction.

[0078] See also Figure 2 The hinge assembly 100 may include a base 10, a first swing arm 20, a second swing arm 25, and two damping mechanisms 30. One of the damping mechanisms 30 connects the first swing arm 20 and the base 10, so that one end of the first swing arm 20 is rotatably connected to the base 10, and the rotation of the first swing arm 20 can cause the damping mechanism 30 to produce a damping effect; the other damping mechanism 30 connects the second swing arm 25 and the base 10, so that one end of the second swing arm 25 is rotatably connected to the base 10, and the rotation of the second swing arm 25 can cause the damping mechanism 30 to produce a damping effect.

[0079] The hinge assembly 100 further includes a first connecting plate 40, a first supporting plate 45, a second connecting plate 50 and a second supporting plate 55. One end of the first connecting plate 40 and one end of the second connecting plate 50 are both rotatably connected to the base 10, the first supporting plate 45 is rotatably connected to one end of the first connecting plate 40, and the second supporting plate 55 is rotatably connected to one end of the second connecting plate 50. One end of the first swing arm 20 away from the base 10 is slidably connected to the first connecting plate 40, and one end of the second swing arm 25 away from the base 10 is slidably connected to the second connecting plate 50.

[0080] The first support plate 45 is used to connect with the first body 210, and the second support plate 55 is used to connect with the second body 220. The rotation axis of the first support plate 45 relative to the base 10 is jointly determined by the rotation axis of the first support plate 45 relative to the first connecting plate 40 and the rotation axis of the first connecting plate 40 relative to the base 10, so the rotation axis of the first support plate 45 relative to the base 10 is not coaxial with the rotation axis of the damping mechanism 30 relative to the base 10; the rotation axis of the second support plate 55 relative to the base 10 is jointly determined by the rotation axis of the second support plate 55 relative to the second connecting plate 50 and the rotation axis of the second connecting plate 50 relative to the base 10, so the rotation axis of the second support plate 55 relative to the base 10 is not coaxial with the rotation axis of the damping mechanism 30 relative to the base 10.

[0081] When the user applies a force to the first body 210, the first body 210 drives the first support plate 45 to rotate, and the first support plate 45 drives the first connecting plate 40 to rotate; the first support plate 45 drives the first swing arm 20 to rotate relative to the base 10 and slide relative to the first support plate 45. When the user applies a force to the second body 220, the second body 220 drives the second support plate 55 to rotate, and the second support plate 55 drives the second connecting plate 50 to rotate; the second support plate 55 drives the second swing arm 25 to rotate relative to the base 10 and slide relative to the second support plate 55.

[0082] A first slide groove 451 is formed on the surface of the first support plate 45 facing the first swing arm 20. The first slide groove 451 extends from the side of the first support plate 45 close to the base 10 to the side away from the base 10. The first swing arm 20 is accommodated in the first slide groove 451. When the first support plate 45 rotates relative to the base 10, the first swing arm 20 slides in the first slide groove 451.

[0083] A second slide groove 551 is formed on the surface of the second support plate 55 facing the second swing arm 25. The second slide groove 551 extends from the side of the second support plate 55 close to the base 10 to the side away from the base 10. The second swing arm 25 is accommodated in the second slide groove 551. When the second support plate 55 rotates relative to the base 10, the second swing arm 25 slides in the second slide groove 551.

[0084] See also Figure 4 The base 10 includes a first base 11 and a second base 13, and the first base 11 and the second base 13 are relatively fixed. The first base 11 and the second base 13 can be two relatively separated components, or can be an integrated structure.

[0085] A first arc-shaped limiting groove 15 and a second arc-shaped limiting groove 17 are formed between the first base 11 and the second base 13. The first limiting groove 15 includes a first abutting wall (not shown), and the second limiting groove 17 includes a second abutting wall 171. The opening directions of the first limiting groove 15 and the second limiting groove 17 are opposite.

[0086] The hinge assembly 100 further includes a first limiting member 60 and a second limiting member 70. The first limiting member 60 is fixed to the first connecting plate 40, and the second limiting member 70 is fixed to the second connecting plate 50. The first limiting member 60 includes a first limiting portion 61 and a second limiting portion 63. The first limiting portion 61 and the second limiting portion 63 are two ends of the first limiting member 60, and both the first limiting portion 61 and the second limiting portion 63 are in an arc shape. The second limiting member 70 includes a third limiting portion 71 and a fourth limiting portion 73. The third limiting portion 71 and the fourth limiting portion 73 are two ends of the second limiting member 70, and both the third limiting portion 71 and the fourth limiting portion 73 are in an arc shape.

[0087] The first limiting portion 61 is accommodated in the first limiting groove 15, the first limiting groove 15 is used to limit the rotation angle of the first connecting plate 40 relative to the base 10, and the first abutting wall is used to limit the rotation end point of the first connecting plate 40 relative to the base 10. The third limiting portion 71 is accommodated in the second limiting groove 17, the second limiting groove 17 is used to limit the rotation angle of the second connecting plate 50 relative to the base 10, and the second abutting wall 171 is used to limit the rotation end point of the second connecting plate 50 relative to the base 10.

[0088] The hinge assembly 100 further includes a first fixing member 80 and a second fixing member 90, one end of the first fixing member 80 is fixed to the first support plate 45, and one end of the second fixing member 90 is fixed to the second support plate 55. A third arc-shaped limiting groove 81 is provided at one end of the first fixing member 80 away from the first support plate 45, and the second limiting portion 63 is accommodated in the third limiting groove 81, and the third limiting groove 81 is used to limit the rotation angle of the first support plate 45 relative to the first connecting plate 40. A fourth arc-shaped limiting groove 91 is provided at one end of the second fixing member 90 away from the second support plate 55, and the fourth limiting portion 73 is accommodated in the fourth limiting groove 91, and the fourth limiting groove 91 is used to limit the rotation angle of the second support plate 55 relative to the second connecting plate 50.

[0089] See also Figure 5Each damping mechanism 30 may include an elastic member 31 and a sliding frame 33. The sliding frame 33 is provided with a receiving groove 331, and the elastic member 31 is received in the receiving groove 331. The first swing arm 20 is provided with a first receiving groove 201, and the second swing arm 25 is provided with a second receiving groove 251. The first receiving groove 201 and the second receiving groove 251 are used to receive the elastic member 31 and the sliding frame 33 on the corresponding side. The sliding frame 33 is slidably disposed in the first receiving groove 201 and the second receiving groove 251, respectively. Along the direction in which the elastic member 31 can be compressed, one end of the elastic member 31 abuts against the first swing arm 20, and the other end of the elastic member 31 abuts against the sliding frame 33. When the sliding frame 33 slides relative to the first swing arm 20, the distance between the sliding frame 33 and the first swing arm 20 changes, and the elastic member 31 produces elastic deformation. Similarly, when the sliding frame 33 slides relative to the second swing arm 25, the distance between the sliding frame 33 and the second swing arm 25 changes, and the elastic member 31 produces elastic deformation.

[0090] The damping mechanism 30 further includes a roller 35 and a latch 37, wherein the latch 37 is disposed through the roller 35. The roller 35 is located on the side of the sliding frame 33 facing the base 10, and both ends of the latch 37 are also disposed through the sliding frame 33, and the roller 35 can rotate relative to the sliding frame 33.

[0091] The second base 13 includes a first interference portion 132 and a second interference portion 134, which protrude toward the corresponding two damping mechanisms 30, respectively, and are respectively located on the rotation track of the corresponding roller 35, thereby interfering with the rotation track of the sliding frame 33, so that the sliding frame 33 moves relative to the first swing arm 20 or the second swing arm 25. The provision of the roller 35 can make the first interference portion 132 and the second interference portion 134 squeeze the sliding frame 33 more smoothly, thereby ensuring the damping feel of the damping mechanism 30.

[0092] See also Figures 6 to 8 , Figure 6 This is a cross-sectional schematic diagram of the hinge assembly 100 provided in an embodiment of the present application in a flattened state. Figure 7 This is a cross-sectional schematic diagram of a hinge assembly 100 provided in an embodiment of the present application, in which a first support plate 45 and a second support plate 55 form a certain angle. Figure 8 This is a cross-sectional schematic diagram of the hinge assembly 100 provided in an embodiment of the present application in a folded state.

[0093] See also Figure 6When the hinge assembly 100 is in the flattened state, the first support plate 45 and the second support plate 55 are in the same plane, one end of the elastic member 31 in the damping mechanism 30 in the first swing arm 20 abuts against the first swing arm 20, and the other end abuts against the sliding frame 33; one end of the elastic member 31 in the damping mechanism 30 in the second swing arm 25 abuts against the second swing arm 25, and the other end abuts against the sliding frame 33, and the two rollers 35 are in contact with the first interference portion 132 and the second interference portion 134 respectively. At this time, the elastic member 31 is in the initial state, which can be in a compressed state or in a non-compressed state.

[0094] See also Figure 7 During the relative rotation of the first support plate 45 and the second support plate 55, the first support plate 45 drives the first swing arm 20 to rotate relative to the base 10, and the first swing arm 20 drives the damping mechanism 30 accommodated in the first receiving groove 201 to rotate relative to the base 10. At the same time, the first interference portion 132 interferes with the rotation path of the roller 35, so that the roller 35 moves toward the direction of the sliding frame 33, thereby squeezing the elastic member 31. Similarly, the second support plate 55 drives the second swing arm 25 to rotate relative to the base 10, and the second swing arm 25 drives the damping mechanism 30 accommodated in the second receiving groove 251 to rotate relative to the base 10. At the same time, the second interference portion 134 interferes with the rotation path of the roller 35, so that the roller 35 moves toward the direction of the sliding frame 33, thereby squeezing the elastic member 31.

[0095] See also Figure 8 , and further rotate the first support plate 45 and the second support plate 55 relative to each other until the hinge assembly 100 is in a folded state, and the roller 35 is separated from the first interference portion 132 and the second interference portion 134 respectively, and the rotation path of the roller 35 is not affected by the first interference portion 132 and the second interference portion 134, and the elastic member 31 returns to its initial state under its own elastic recovery action.

[0096] When the hinge assembly 100 is opened from the folded state to the flattened state, the movement process is similar to the above process and will not be repeated here.

[0097] Please also read Fig. 9 and Fig.10 , Fig. 9 This is a schematic diagram of the structure of the elastic member 31 provided in the embodiment of the present application. Fig.10 This is a front view of the elastic member 31 provided in the embodiment of the present application.

[0098] The elastic member 31 includes at least one elastic unit 310, that is, the elastic member 31 can be one elastic unit 310, or can include multiple elastic units 310, wherein the multiple elastic units 310 are interconnected to form a whole, or can be formed by assembling independent elastic units 310. Fig.11 When the elastic member 31 is used in the hinge assembly 100, multiple elastic members 31 can be stacked and used according to actual damping requirements. The number and stacking method of the multiple elastic members 31 can be adjusted according to actual requirements. For example, the multiple elastic members 31 can be stacked in different directions (such as Fig.11 (a)), multiple elastic members 31 may also be stacked in the same direction (e.g. Fig.11 (b)). Alternatively, elastic members 31 of different sizes may be used in conjunction with each other, for example, at least a portion of one elastic member 31 is accommodated in another elastic member 31. Fig.12 , the smaller elastic member 31 is placed in the second gap 318 of the larger elastic member 31, the two first beams 311 of the two elastic members 31 are in contact with each other, the two second beams 313 of the two elastic members 31 are in contact with each other, and the installation volume of the two elastic members 31 is only the volume of the larger elastic member 31. When the number of elastic units 310 in the elastic member 31 is small, for example, there is only one elastic unit 310, the processing technology of the elastic member 31 is simple, and the processing cost is saved; and the number of elastic members 31 can be increased or decreased according to actual needs.

[0099] Please refer again Fig. 9 , each elastic unit 310 includes a first beam portion 311, a second beam portion 313 and an elastic portion 315. In each elastic unit 310, the first beam portion 311 and the second beam portion 313 are connected to the two ends of the elastic portion 315. The first beam portion 311 extends along the first direction L1 relative to the elastic portion 315, and the second beam portion 313 extends along the second direction L2 relative to the elastic portion 315. When the elastic member 31 is subjected to a force along the third direction L3, the elastic portion 315 generates elastic deformation; when the force is removed, the elastic portion 315 restores the deformation. The third direction L3 intersects with the first direction L1 and the second direction L2, respectively. Figure 2 In the hinge assembly 100 shown, the third direction L3 is the direction in which the roller 35 presses the sliding frame 33 .

[0100] See also Fig. 9 , Fig.10 Combined with Figure 2, the first cross beam portion 311 and the second cross beam portion 313 can both be flat, and the elastic portion 315 is curved. The elastic member 31 can be formed by bending a plate-like material. The first cross beam portion 311 and the second cross beam portion 313 are both flat, which is also beneficial to the processing of the elastic member 31. When the elastic member 31 is applied to the hinge assembly 100, the first cross beam portion 311 and the second cross beam portion 313 are used to play a contact role, for example, the first cross beam portion 311 abuts against the surface of the sliding frame 33, and the second cross beam portion 313 abuts against the surface of the first swing arm 20. The flat first cross beam portion 311 and the second cross beam portion 313 are beneficial to have good contact with the elements acting on the elastic member 31, so as to help balance the force acting on the elastic member 31.

[0101] The first cross beam portion 311 includes a first abutting surface 3112, which is the surface of the first cross beam portion 311 away from the second cross beam portion 313; the second cross beam portion 313 includes a second abutting surface 3132, which is the surface of the second cross beam portion 313 away from the first cross beam portion 311. The first abutting surface 3112 and the second abutting surface 3132 are parallel to each other so that the elastic member 31 is evenly stressed. Both the first abutting surface 3112 and the second abutting surface 3132 are planes. When a force is applied to the elastic member 31 along the third direction L3, the third direction L3 is perpendicular to the first abutting surface 3112 and the second abutting surface 3132.

[0102] The first cross beam 311 and the second cross beam 313 are located on the same side of the elastic part 315 and both extend in a direction away from the elastic part 315. The extension directions of the first cross beam 311 and the second cross beam 313 are parallel, that is, the first direction L1 and the second direction L2 are parallel. The curved elastic part 315 is surrounded to form a first gap 317, and the first cross beam 311 and the second cross beam 313 are spaced to form a second gap 318. The first gap 317 and the second gap 318 are interconnected, and the elastic part 315 protrudes outward from the second gap 318 relative to the first cross beam 311 and the second cross beam 313. The elastic member 31 composed of the elastic part 315, the first cross beam 311 and the second cross beam 313 is roughly in a semi-enclosed U shape.

[0103] When the elastic member 31 is subjected to a force along the third direction L3, the force acts on the first beam portion 311 and / or the second beam portion 313, the distance between the first beam portion 311 and the second beam portion 313 changes, the size of the second gap 318 changes, so that the elastic portion 315 further protrudes outward to produce elastic deformation, the size of the first gap 317 also changes, and the first gap 317 and the second gap 318 simultaneously provide deformation space for the deformation of the elastic member 31. In this embodiment, the third direction L3 is perpendicular to the first direction L1 and the second direction L2.

[0104] In the direction perpendicular to the first direction L1 or the second direction L2, the thickness of the first beam portion 311 and the second beam portion 313 may be the same or different. The thickness of the elastic portion 315, the first beam portion 311 or the second beam portion 313 may be adjusted according to the required damping.

[0105] See also Fig.13 , the thickness of the first beam portion 311 may be different from the thickness of the second beam portion 313. Fig.14 The thickness of the elastic part 315 is smaller than the thickness of the first beam part 311 and the thickness of the second beam part 313. The smaller thickness of the elastic part 315 is beneficial to reducing the stiffness coefficient of the elastic member 31. Therefore, the elastic member 31 is suitable for terminal products 200 with a larger installation space, such as desktop computers. Fig.15 The thickness of the elastic portion 315 is greater than the thickness of the first beam portion 311 and the thickness of the second beam portion 313. The thickness of the elastic portion 315 is larger, which is beneficial to increase the stiffness coefficient of the elastic member 31. When the elastic member 31 is in the process of elastic deformation, the deformation of the elastic member 31 is small and the required deformation space is small. Therefore, the elastic member 31 is suitable for terminal products 200 with a smaller installation space, such as mobile phones.

[0106] See also Fig.16 , Fig.16 This is a front view of an elastic member 31 provided in some other embodiments of the present application. Fig.10 The difference between the elastic member 31 shown in the figure is that the first gap 317 and the second gap 318 in the elastic member 31 of this embodiment are located on opposite sides of the elastic portion 315, that is, the first gap 317 and the second gap 318 are arranged at intervals by the elastic portion 315, and the elastic portion 315 is recessed inwardly toward the second gap 318 relative to the first beam portion 311 and the second beam portion 313. When the elastic member 31 is subjected to a force, the distance between the first beam portion 311 and the second beam portion 313 changes, and the size of the second gap 318 changes, so that the elastic portion 315 further recesses inwardly to produce elastic deformation, and the size of the first gap 317 also changes. The first gap 317 and the second gap 318 simultaneously provide deformation space for the deformation of the elastic member 31. Among them, since the elastic portion 315 is recessed inwardly, that is, along the third direction L3, the elastic portion 315 is located within the projection range of the first beam portion 311 and the second beam portion 313, relative to Fig.10 The elastic member 31 shown, under the same magnitude of force, Fig.16 The elastic member 31 shown is more difficult to compress, i.e. Fig.16 The elastic element 31 shown has a greater stiffness coefficient.

[0107] Fig.17 , Fig.18 as well as Fig.19All of them are front views of the elastic member 31 including a plurality of elastic units 310 and being an integral structure. At least two elastic units 310 are interconnected to form a whole. When the elastic member 31 includes at least two elastic units 310, the stiffness coefficient of the elastic member 31 can be increased compared to a single elastic unit 310, which is also beneficial to the installation of the elastic member 31. The shapes, sizes, etc. of the plurality of elastic units 310 may be the same or different; the arrangement of the plurality of elastic units 310 is not limited. In other embodiments, the connection methods include but are not limited to welding, bonding, hot melt connection, fastener locking, and the like.

The cross section of the elastic member 31 is roughly in the shape of a runway.

[0111] See also Fig. 20 , Fig. 20 This is a front view of an elastic member 31 provided in some other embodiments of the present application. Fig.10 The elastic member 31 shown is different in that Fig. 20 There is an angle between the first beam portion 311 and the second beam portion 313 in the elastic member 31 shown, and the angle range is greater than 0° and less than 180°, that is, the angle between the first direction L1 and the second direction L2 is greater than 0° and less than 180°, for example, it can be 30°, 60°, 90°, 120°, etc.

[0112] In some embodiments, the angle ranges from 30° to 120°, which is beneficial for ensuring the deformation space of the elastic member 31 and also helps the elastic member 31 to have a suitable stiffness coefficient.

[0113] The elastic part 315 is surrounded to form a first gap 317. The first beam part 311 and the second beam part 313 are spaced apart to form a second gap 318. The first gap 317 and the second gap 318 are connected to each other. The first beam part 311, the elastic part 315 and the second beam part 313 generally form a V shape.

[0114] The first cross beam portion 311 includes a first abutting surface 3112, and the second cross beam portion 313 includes a second abutting surface 3132. The first abutting surface 3112 and the second abutting surface 3132 are parallel to each other. When a force is applied to the elastic member 31 along the third direction L3, the third direction L3 is perpendicular to the first abutting surface 3112 and the second abutting surface 3132. When the elastic member 31 is assembled in the hinge assembly 100, the first abutting surface 3112 can be used to abut against the surface of the sliding frame 33, and the second abutting surface 3132 can be used to abut against the surface of the first swing arm 20.

[0115] In this embodiment, the first abutting surface 3112 is located at an end of the first beam portion 311 away from the elastic portion 315 ; the second abutting surface 3132 is located at an end of the second beam portion 313 away from the elastic portion 315 .

Fig. 20 The elastic member 31 shown is different in that Fig.21 The first abutting surface 3112 in the elastic member 31 shown is the surface of the first beam portion 311 away from the second beam portion 313, and the second abutting surface 3132 is located at the end of the second beam portion 313 away from the elastic portion 315. That is, the first abutting surface 3112 is perpendicular to the third direction L3, and the area of ​​the first abutting surface 3112 is large, which is conducive to increasing the force-bearing area of ​​the elastic member 31, thereby balancing the acting force.

[0117] Fig. 22 as well as Fig.23 All of them are front views of the elastic member 31 including a plurality of elastic units 310. The elastic member 31 includes a plurality of elastic units 310, and at least two elastic units 310 are connected to each other. Two adjacent elastic units 310 may be connected to each other through two elastic portions 315, may be connected through two first cross beam portions 311, may be connected through two second cross beam portions 313, or may be connected through one first cross beam portion 311 and another second cross beam portion 313.

The elastic member 31 is generally X-shaped.

[0119] See also Fig.23 , the two second beams 313 in two adjacent elastic units 310 are connected, and the two first beams 311 in two adjacent elastic units 310 are located on a side away from the second beams 313. The elastic member 31 is substantially M-shaped.

[0120] The elastic member 31 may further include a connecting portion 316, which connects two adjacent elastic units 310. The connecting portion 316 is curved, and the function of the connecting portion 316 is the same as that of the elastic portion 315, that is, the connecting portion 316 may also be deformed. The setting of the connecting portion 316 may increase the structural unit of the elastic member 31 for generating elastic deformation, which is conducive to further improving the elasticity of the elastic member 31.

[0121] See also Fig.24 , Fig.25 as well as Fig.26 , which is a front view of the elastic member 31 provided in some other embodiments of the present application.

[0122] The elastic member 31 in this embodiment includes a first beam portion 311, a second beam portion 313 and an elastic portion 315. The elastic portion 315 is located between the first beam portion 311 and the second beam portion 313. The elastic portion 315 includes a first end 3152, a second end 3154 and a middle section 3156. The first end 3152 and the second end 3154 connect the two ends of the middle section 3156. The middle section 3156 is recessed relative to the first end 3152 and the second end 3154.

The at least two elastic units 310 are arranged in a stacked manner, which is conducive to saving the installation space of the elastic member 31 while meeting the elasticity requirements. In addition, in this embodiment, it is equivalent to installing four elastic members 31 in an installation space slightly larger than that of two elastic members 31.

[0127] See also Fig.30 In some embodiments, at least parts of the middle sections 3156 of the two elastic parts 315 are attached to each other, the two first ends 3152 are spaced apart, and the two second ends 3154 are spaced apart. The force is applied to the elastic member 31 through the middle section 3156, so that the interconnected elastic parts 315 are deformed at the same time; the gap between the two first ends 3152 and the gap between the two second ends 3154 can reduce the deformation effect between the two elastic parts 315.

When the force is applied to the elastic member 31 through the middle section 3156, the two sides of the elastic part 315 located on the outside are elastically deformed outwardly, and the two sides of the elastic part 315 located on the inside are elastically deformed inwardly, so that the elastic deformation areas between the two connected elastic parts 315 will not interfere with each other.

[0129] In some embodiments, the elastic member 31 including only one elastic unit 310 may also be used as Figures 27 to 31 The connection method shown in FIG. 1 is to install multiple elastic members 31 in the hinge assembly 100. It can be understood that multiple elastic members 31 with different sizes in other embodiments can also be stacked in a sleeve manner to reduce the installation volume of the elastic members 31.

[0133] The elastic member 31 provided in the embodiment of the present application is elastically deformed by the elastic portion 315 between the first beam portion 311 and the second beam portion 313, so that the elastic member 31 has a damping effect. Among them, when the elastic member 31 is applied to the hinge assembly 100 or the terminal product 200, it can be used alone, that is, it replaces the technical solution of using a cylindrical spring in conjunction with a central axis in the related art, that is, the elastic member 31 provided in the embodiment of the present application does not need to reserve the installation space required for the central axis, nor does it need to reserve the matching clearance between the cylindrical spring and the central axis in the related art; and there is no risk of the central axis breaking; when the elastic member 31 in the present application is applied to the hinge assembly 100 or the terminal product 200, it can have a variety of assembly methods to increase the scope of application of the elastic member 31; when the elastic member 31 of the present application is used in a superimposed manner, the installation space of the elastic member 31 will not be significantly increased.
