Description

Push-pull mechanism, display screen assembly and push-pull electronic equipment

Technical Field

The application relates to the technical field of electronic equipment, in particular to a push-pull mechanism, a display screen assembly and push-pull electronic equipment.

Background

At present, in terminal equipment, such as push-pull electronic equipment, folding or extending of a flexible display screen is usually achieved through a push-pull mechanism, and folding or extending of the flexible display screen can be achieved respectively through mutual distance or approach of a main moving part and a fixed part in the push-pull mechanism. However, since the sliding of the conventional push-pull mechanism is generally limited by a simple guide rail structure, when the main moving part and the fixed part slide relative to each other, a large movement resistance is easily generated therebetween, thereby causing the main moving part and the fixed part to jam during the relative movement.

Disclosure of Invention

The embodiment of the application provides a push-pull mechanism, a display screen assembly and push-pull electronic equipment.

In a first aspect, an embodiment of the present application provides a push-pull mechanism applied to a push-pull electronic device, where the push-pull mechanism includes a first bracket, a second bracket, and an adjusting assembly, the second bracket is movably connected to the first bracket, and the second bracket and the first bracket can move relatively along a predetermined push-pull direction; the second bracket comprises a main body and a mounting part connected with the main body, and the mounting part and the first bracket are arranged at intervals; the adjusting component is arranged on the mounting part; the adjusting component comprises a force applying piece, and the force applying piece elastically supports against the first support to provide supporting force for the first support.

In a second aspect, an embodiment of the present application provides a display screen assembly, which includes a flexible display screen and the above-mentioned push-pull mechanism, wherein one end of the flexible display screen is connected to the first support, and the other end of the flexible display screen is connected to the second support, so that the flexible display screen can be selectively folded or unfolded when the first support and the second support slide relatively.

In a third aspect, an embodiment of the present application further provides a push-pull electronic device, including the above push-pull mechanism.

The push-and-pull mechanism that this application embodiment provided provides the holding power through the application of force spare of adjusting part to first support, in order to keep the relative position relation between first support and the second support, make first support and second support be difficult for taking place the skew for the push-and-pull direction, can keep certain clearance between the part of first support and second support relative slip, avoid first support and second support to contact and produce the motion and interfere, can guarantee that the motion resistance between first support and the second support is less relatively, make first support and second support relative slip more smooth and easy.

Further, because the force application member elastically abuts against the first support, when at least one of the first support and the second support is subjected to an external force to generate a tendency of offsetting relative to the push-pull direction, the force application member can buffer the external force to a certain extent so as to reduce the relative offsetting of the first support and the second support caused by the external force. In some cases, because the force application member elastically abuts against the first support, the force application member can reduce the external force and can reduce the relative offset between the first support and the second support caused by the external force by utilizing the elastic deformation generated by the elastic abutting force of the force application member while buffering the external force. Further, when the external force disappears, the force application part recovers deformation under the action of the elastic force to push the first support to move relative to the second support, so that the relative offset between the second support and the first support can be eliminated, a certain gap can be kept between the relative sliding parts of the first support and the second support, and movement interference caused by large-area contact of the first support and the second support is avoided.

Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It should be apparent that the described embodiments are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

As used in embodiments herein, "communication terminal" (or simply "terminal"), "electronic device" includes, but is not limited to, devices that are configured to receive/transmit communication signals via a wireline connection, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network, and/or via a wireless interface (e.g., for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal). Communication terminals arranged to communicate over a wireless interface may be referred to as "wireless communication terminals", "wireless terminals", and/or "mobile terminals". Examples of mobile terminals, electronic devices include, but are not limited to, satellite or cellular telephones; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; a PDA that can include a radiotelephone, pager, internet/intranet access, web browser, memo pad, calendar and/or Global Positioning System (GPS) receiver; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

The push-pull mechanism in the existing push-pull electronic equipment generally comprises a main moving part and a fixed part, wherein the main moving part is connected with the fixed part in a sliding manner, the main moving part and the fixed part can be unfolded or folded when being relatively far away from or close to each other, the inventor finds that the main moving part and the fixed part are generally influenced by assembly tolerance, external force action, uneven distribution of movement resistance and the like, the main moving part and the fixed part are easy to deviate relative to the push-pull direction, so that the side direction of the main moving part is easy to offset with the side direction of the fixed part to cause interference, larger movement resistance can be generated between the main moving part and the fixed part, and the problems of movement jamming and the like can be easily caused when the main moving part and the fixed part relatively slide. In view of the above technical problems, the applicant of the present application proposes a push-pull mechanism, a display screen assembly and a push-pull electronic device to improve the above problems.

Referring to fig. 1 and fig. 2 together, the present application provides a push-pull electronic device 400, where the push-pull electronic device 400 includes a display screen assembly 300 and an electronic component (omitted from the drawings), and the display screen assembly 300 includes a flexible display screen 200 and a push-pull mechanism 100. The electronic component may include a control motherboard, a sensor, a fingerprint module, an iris recognition module, a microphone, etc., and the electronic component may be disposed in the cavity structure of the push-pull mechanism 110, and the push-pull electronic device 400 may be, but is not limited to, an electronic device such as a mobile phone, a tablet computer, a smart watch, etc. The electronic device 400 of the present embodiment is described by taking a mobile phone as an example.

Referring to fig. 3, the push-pull mechanism 100 includes a first bracket 110, a second bracket 120, and an adjusting assembly 130. The second bracket 120 is movably connected to the first bracket 110, and the second bracket 120 and the first bracket 110 are relatively movable along a predetermined push-pull direction X, wherein the first bracket 110 and the second bracket 120 are slidably connected. As shown in fig. 3, the coordinate system shows a push-pull direction X, a length direction Y and a thickness direction Z of the push-pull mechanism 100, respectively, wherein the push-pull direction X may be substantially perpendicular to the length direction Y and the thickness direction Z, and the length direction Y may be substantially perpendicular to the thickness direction Z. The adjusting assembly 130 is disposed on the second bracket 120 and abuts against the first bracket 110 to provide a supporting force to the first bracket 110, and a direction of the supporting force intersects with the push-pull direction X, for example, an included angle between the supporting force and the push-pull direction X may be greater than 0 ° and less than or equal to 90 °. The supporting force can be used to maintain the relative position relationship between the first bracket 110 and the second bracket 120, and avoid the interference caused by the deviation of the first bracket 110 and the second bracket 120 relative to the push-pull direction X.

When the first bracket 110 and the second bracket 120 slide relatively, the first end 118 of the first bracket 110 far away from the second bracket 120 and the second end 119 of the second bracket 120 far away from the first bracket 110 selectively move close to or away from each other. The push-pull electronic device 400 can drive the first support 110 and the second support 120 to slide relative to each other by a driving mechanism (e.g., a motor, an air cylinder, etc.), or can drive the first support 110 and the second support 120 to slide relative to each other by manual pushing and pulling. As shown in fig. 1, when the push-pull electronic device 400 is in the initial state, the first bracket 110 and the second bracket 120 are in a state of being substantially overlapped with each other, and the distance between the first end 118 and the second end 119 is defined as a first distance. First end 118 and second end 119 can move away from each other when a user provides a pulling force to first brace 110 and/or second brace 120. As shown in fig. 2, when the push-pull electronic device 400 is in the unfolded state, a distance between the first end 118 and the second end 119 is defined as a second distance, wherein the second distance is greater than the first distance, for example, the second distance may be greater than 1 time or more than 1 time of the first distance, and when a user provides a pushing force to the first support 110 and/or the second support 120, the first end 118 and the second end 119 can be close to each other.

As shown in fig. 2, one end of the flexible display 200 may be connected to the first bracket 110, and the other end may be connected to the second bracket 120, so as to be selectively folded or unfolded when the first bracket 110 and the second bracket 120 slide relative to each other. In the present embodiment, the flexible display 200 has a display function, or may have both a display function and a function of responding to a touch operation. The flexible display screen 200 is also called a rollable display, and is a display device that can be flexibly deformed by making a visible flexible panel of a flexible material such as ultra-thin glass, plastic, or metal foil.

In this embodiment, the flexible display screen 200 may be continuously laid on the same side of the first support 110 and the second support 120, the first support 110 and the second support 120 may support the flexible display screen 200, and the flexible display screen 200 may be partially laid on the other side of the first support 110 or the second support 120. Illustratively, one end of the flexible display 200 may be connected to the first end portion 118 and the other end may be connected to the second end portion 119.

As shown in fig. 1, when the first end portion 118 and the second end portion 119 are close to each other, the flexible display screen 200 is continuously folded, and the length of the display area on the same side of the first support 110 and the second support 120 along the push-pull direction X is continuously reduced, so as to achieve the first display mode shown in fig. 1, where the screen width of the first display mode is determined by the maximum width after the first support 110 and the second support 120 are folded.

As shown in fig. 2, when the first end portion 118 and the second end portion 119 are far away from each other, the flexible display screen 200 is continuously unfolded, and the length of the display area on the same side of the first support 110 and the second support 120 along the push-pull direction X is continuously increased, so that the second display mode shown in fig. 2 can be finally achieved, and the display width of the second display mode is determined by the farthest distance that the first support 110 and the second support 120 can be relatively pulled apart.

By changing the sliding distance between the first support 110 and the second support 120 along the push-pull direction X, the area of the display area of the flexible display screen 200 can be adjusted, so as to meet different requirements of a user, that is, when the first support 110 and the second support 120 move relatively, the flexible display screen 200 can be selectively switched to the first display mode or the second display mode. In addition to the first display mode and the second display mode described above, the flexible display 200 may also be displayed in other widths as needed.

Referring to fig. 3 and 4, in the present embodiment, the first bracket 110 is provided with a side wall 111, the side wall 111 may be substantially in a planar structure, and the side wall 111 may be substantially disposed along the push-pull direction X, where "disposed along the push-pull direction X" may mean that the side wall 111 is substantially parallel to the push-pull direction X, and specifically, the side wall 111 may be substantially parallel to a plane defined by the push-pull direction X and the thickness direction Z of the push-pull mechanism 100. The sidewall 111 may be a solid surface with a relatively low roughness (e.g., a surface of the first bracket 110 after being ground, polished or coated) to ensure that the frictional resistance between the sidewall 111 and the adjusting assembly 130 is relatively small, so that the first bracket 110 and the second bracket 120 can slide relatively smoothly. Specifically, in the present embodiment, the first bracket 110 may include a main body portion 112 and a cover plate 113, the cover plate 113 is disposed on the main body portion 112, and the sidewall 111 may be located on the cover plate 113.

Referring to fig. 4 and 5, in the present embodiment, the main body 112 is substantially a hollow frame structure, and the main body 112 has a receiving cavity 1125, and the receiving cavity 1125 can be used for receiving electronic components such as a circuit board, a sensor, a speaker, and a battery. Specifically, the main body 112 may include a bottom plate 1121 and a frame 1122 surrounding the bottom plate 1121, the bottom plate 1121 includes a back mounting surface 1123 and a mounting surface 1124 opposite to each other, the frame 1122 may include a plurality of frames connected in sequence, and the frame 1122 may surround the mounting surface 1121 and protrude toward a side away from the mounting surface 1124 so as to define a receiving cavity 1125 together with the back mounting surface 1123. The frame 1122 includes a support surface 1126, the support surface 1126 faces away from the mounting back surface 1123, and the support surface 1126 is configured to support the cover 113.

In this embodiment, the cover plate 113 may be located on a side of the frame 1122 away from the mounting back surface 1123, wherein the cover plate 113 is disposed on the supporting surface 1126 and covers the receiving cavity 1125, the cover plate 113 is detachably connected to the body 112, and the cover plate 113 covers the receiving cavity 1125, so that an electronic component disposed in the receiving cavity 1125 is prevented from being exposed, and the electronic component is protected.

As an example, the cover plate 113 may include a cover plate 1133, a first plate 1131, and a second plate 1132. Specifically, the cover plate 1133 is substantially a flat plate, the first plate 1131 and the second plate 1132 are respectively connected to two opposite sides of the cover plate 1133 and are bent toward the same side of the cover plate 1133, and the first plate 1131 and the second plate 1132 may be disposed substantially along the push-pull direction X. Cover plate 1133, first plate 1131, and second plate 1132 may be integrally formed, for example, by stamping, bending, welding, and the like.

In some embodiments, the bending angles of first and

second plate bodies

1131, 1132 with respect to cover plate 1133 may be substantially the same, for example, the bending angle may be greater than 0 ° and less than or equal to 90 °, or the bending angle may also be greater than 90 °, for example, the bending angles of first and

second plate bodies

1131, 1132 are both substantially 90 °, in which case first and

second plate bodies

1131, 1132 may be substantially perpendicular to supporting surface 1126, and first and

second plate bodies

1131, 1132 may be supported between supporting surface 1126 and cover plate 1133. In some embodiments, the bending angles of first and

second plate bodies

1131, 1132 with respect to cover plate 1133 may be the same or different.

In this embodiment, the number of the sidewalls 111 may be two, and the two sidewalls 111 may be respectively disposed on two opposite sides of the first bracket 110. Specifically, in the present embodiment, the two sidewalls 111 may be respectively disposed on the first board 1131 and the second board 1132. The opposite sides of the first bracket 110 may be respectively subjected to at least one supporting force, that is, the first plate 1131 and the second plate 1132 are respectively subjected to the supporting force provided by the adjusting assembly 130, and the first bracket 110 can keep the stress balance of the opposite sides under the supporting force, so that the first bracket 110 and the second bracket 120 are not easily deviated relative to the push-pull direction X, and the interference caused by the lateral opposition of the first bracket 110 and the second bracket 120 when the first bracket 110 and the second bracket 120 move relatively is avoided. Since the structure of the covering plate 113 is simpler than that of the main body 112, the side wall 111 is provided on the covering plate 113, so that the processing of the covering plate 113 is facilitated, and in addition, the side wall 111 is also smoothed, so that the frictional resistance between the force application member 132 and the side wall 111 is small.

In some embodiments, the sidewall 111 may also be located only on the first plate 1131 or the second plate 1132. When one side of the first bracket 110 is applied with the supporting force, that is, only the first plate 1131 or the second plate 1132 is applied with the supporting force from the force applying member 132, the inclination of the first bracket 110 toward the side of the second bracket 120 can be corrected by applying the supporting force to the one side of the first bracket 110.

In some embodiments, the side wall 111 may be located at the body portion 112, and for example, the body portion 112 may include a side plate 1127, wherein the side plate 1127 may be protruded from the supporting surface 1126 of the frame 1122, and the side plate 1127 may be integrally formed with the frame 1122, wherein the side plate 1127 may be substantially disposed along the push-pull direction X. The number of the side plates 1127 may be 1 or 2, for example, the number of the side plates 1127 is two, the two side plates 1127 are oppositely disposed at an interval and are respectively located at two sides of the accommodating cavity 1125, the number of the side walls 111 may also be two, the two side walls 111 are respectively disposed on the two side plates 1127, and the cover 1133 of the cover plate 113 may be directly disposed on the side plates 1127. The two side plates 1127 may correspond to the at least one adjusting assembly 130, respectively, that is, the two side plates 1127 may receive the supporting force from the at least one adjusting assembly 130, respectively.

Referring to fig. 4 and 5, in the present embodiment, the second bracket 120 includes a main body 121 and a mounting portion 122 connected to the main body 121, the mounting portion 122 refers to a portion of the second bracket 120 for mounting the adjusting assembly 130, the main body 121 may be slidably connected to the first bracket 110, the mounting portion 122 is disposed opposite to the first bracket 110 at an interval, and the mounting portion 122 may be disposed opposite to the side wall 111 of the first bracket 110 at an interval. The adjustment assembly 130 is disposed on the mounting portion 122.

Referring to fig. 5 and 6, the adjusting assembly 130 may include a force applying member 132, the force applying member 132 elastically abuts against the first bracket 110 to provide a supporting force to the first bracket 110, and the force applying member 132 elastically abuts against the side wall 111. The force applying member 132 has elastic deformation capability, and the force applying member 132 and the first bracket 110 are compressed and deformed due to extrusion, so that the force applying member 132 has elastic potential energy, and can be referred to as "elastically abutting". Wherein the elastic deformation capability of the force application member 132 can be the elastic force of itself or the elastic force provided by the external elastic structure.

In some embodiments, the force applying element 132 may also elastically abut against the bottom wall of the first bracket 110, for example, the mounting portion 122 may be disposed at an interval opposite to the mounting back surface 1123, and the force applying element 132 may also elastically abut against the mounting back surface 1123 of the bottom plate 1121, so that a gap may be maintained between the mounting portion 122 and the mounting back surface 1123, a contact area between the first bracket 110 and the second bracket 120 is reduced, and a small movement resistance between the first bracket 110 and the second bracket 120 is ensured, so that the first bracket 110 and the second bracket 120 slide relatively more smoothly.

Referring to fig. 5 and fig. 6, in the present embodiment, the main body 121 may include a frame 1211 and an extension portion 1212, the frame 1211 is substantially in a rectangular plate shape and is disposed substantially along the length direction Y, that is, along a direction perpendicular to the push-pull direction X, the extension portion 1212 is substantially in a strip plate shape, the extension portion 1212 is connected to a side of the frame 1211 facing the first bracket 110, the extension portion 1212 is disposed substantially along the push-pull direction X, the extension portion 1212 may be disposed opposite to the first bracket 110 at an interval, specifically, the extension portion 1212 may be disposed opposite to the side wall 111 at an interval, and the mounting portion 122 is disposed on the extension portion 1212. The extension portion 1212 includes opposite first and

second ends

1213, 1214, the first end 1213 is connected to the bezel 1211, and the second end 1214 is located at an end of the extension portion 1212 remote from the bezel 211, wherein the mounting portion 122 may be located at the second end 1214. The extension 1212 may be spaced opposite the sidewall 111 of the first bracket 110 and the mounting portion 122 may be spaced opposite the sidewall 111 to reduce frictional resistance between the extension 1212 and the sidewall 111.

In this embodiment, the number of the extending portions 1212 may be two, the extending direction of the two extending portions 1212 may be substantially parallel to the push-pull direction X, the two extending portions 1212 may be connected to two opposite ends of the frame 1211 and are both located on the same side of the frame 1211, and the extending portions 1212 and the frame 1211 may be integrally formed. The spacing between the two extensions 1212 may be greater than the spacing between the two sidewalls 111 of the first bracket 110, such that the two sidewalls 111 are located between the two extensions 1212.

When the second bracket 120 is assembled to the first bracket 110, the two extensions 1212 may be located on two opposite sides of the covering panel 113, respectively, and may be slidably disposed relative to the supporting surface 1126, specifically, the two extensions 1212 may be located on the supporting surface 1126, and the extensions 1212 may be spaced relative to the supporting surface 1126 to reduce frictional resistance between the extensions 1212 and the supporting surface 1126, or the extensions 1212 may be slidably disposed on the supporting surface 1126, and the supporting surface 1126 may support the extensions 1212. One of the extensions 1212 has a first side 1215 facing the first plate 1131 and the other extension 1212 has a second side 1216 facing the second plate 1132. When the second bracket 120 and the first bracket 110 are not offset with respect to the push-pull direction X, the first side surface 1215 may be parallel to and spaced apart from the first plate 1131, and the second side surface 1216 may be parallel to and spaced apart from the second plate 1132, so that when the second bracket 120 slides relative to the first bracket 110, the first side surface 1215 may not substantially abut against the first plate 1131, and the second side surface 1216 may not substantially abut against the second plate 1132, so that lateral directions of the first bracket 110 and the second bracket 120 may not interfere with each other, and friction resistance between the first bracket 110 and the second bracket 120 is reduced, so that the second bracket 120 and the first bracket 110 can slide smoothly relative to each other.

In some embodiments, as shown in fig. 7, the number of the force application members 132 of the adjusting assembly 130 may be two, two force application members 132 are respectively mounted on the mounting portions 122 of the two extending portions 1212 and are respectively located at two opposite sides of the first bracket 110, and each force application member 1322 is used for providing an elastic supporting force to the corresponding first bracket 110. As an example, the two force applying members 132 may be respectively disposed at the second ends 1214 of the two extending portions 1212, and since the extending portions 1212 have a certain extending length, the second ends 1214 of the extending portions 1212, which are far away from the rim 1211, are more easily inclined toward the second bracket 120 than the first ends 1213 under the action of an external force, so that the influence of the external force on the first bracket 110 may be reduced by disposing the force applying members 132 at the second ends 1214. The two force applying members 132 may respectively provide supporting forces in opposite directions to the first bracket 110, a direction of the supporting forces may be consistent with the length direction Y, that is, the direction of the supporting forces is substantially perpendicular to the push-pull direction X, and magnitudes of the supporting forces provided by the two force applying members 132 may be substantially the same, so that opposite sides of the first bracket 110 are balanced to prevent the first bracket 110 and the second bracket 120 from tilting relatively, the first side surface 1215 may be opposite to and spaced from the first plate 1131, and the second side surface 1216 may be opposite to and spaced from the second plate 1132, so as to effectively reduce frictional resistance between the first bracket 110 and the second bracket 120.

In one example, as shown in fig. 7 and 8, when the opposite sides of the first bracket 110 and the second bracket 120 are stressed equally, the side wall 111 may be substantially parallel to the side wall 111, such that the first side surface 1223 is spaced apart from and parallel to the side wall 111 of the first board 1131, the second side surface 1224 is spaced apart from and parallel to the side wall 111 of the second board 1132, the force applied to the first board 1131 by the adjusting assembly 130 and the force applied to the second board 1132 are opposite in direction, and the magnitudes of the forces applied by the two adjusting assemblies 130 may be substantially equal to ensure that the opposite sides of the first bracket 110 are stressed equally. When the first bracket 110 and the second bracket 120 slide relatively, the first side surface 1223 and the first plate 1131, and the second side surface 1224 and the second plate 1132 can always keep a space and be substantially parallel to each other, so as to avoid interference caused by mutual offset, reduce the motion resistance between the first bracket 110 and the second bracket 120, and make the first bracket 110 and the second bracket 120 slide relatively more smoothly

In some application environments, the first bracket 110 or the second bracket 120 may be easily shifted relative to the push-pull direction X due to assembling tolerance, uneven distribution of motion resistance, and external force, for example, as shown in fig. 8, when the first bracket 110 is shifted along the direction X1 relative to the push-pull direction X under the external force, the side wall 111 is shifted to the direction A1 shown in fig. 8 approximately relative to the push-pull direction X, one end of the side wall 111 of the first plate 1131 abuts against the first side face 1125, and one end of the side wall 111 of the second plate 1132 abuts against the second side face 1126, so that there may be interference between the first bracket 110 and the second bracket 120, which may result in increase of friction resistance when the first bracket 110 and the second bracket 120 slide relative to each other, and a phenomenon of motion seizure, and a relative shift amount may occur between the first bracket 110 and the second bracket 120, and the relative shift amount may be a shift amount of the side wall 111 relative to the push-pull direction X may be reduced by supporting the elastic shift of the biasing member 132, which the side wall 111 may be shifted relative to the push-pull direction X1 relative to the push-pull direction X, and the second bracket 110; when the external force disappears, the force applying member 132 is deformed under the action of the elastic force to push the first support 110 to rotate by a corresponding angle along the X2 direction (opposite to the X1 direction) relative to the push-pull direction X relative to the first support 110, so that the side wall 111 is parallel to the push-pull direction X again, and thus the side wall 111 of the first plate 1131 is spaced from and parallel to the first side surface 1125, and the side wall 111 of the second plate 1132 is spaced from and parallel to the second side surface 1126, so that a certain gap is maintained between the first support 110 and the second support 120 in the lateral direction, and the first support 110 and the second support 120 can slide smoothly.

In yet another example, when the first bracket 110 is shifted in the X2 direction with respect to the push-pull direction X by an external force, the side wall 111 is shifted to a direction substantially as shown in A2 in fig. 8 with respect to the push-pull direction X, the other end of the side wall 111 of the first plate 1131 abuts against the first side surface 1125, and the other end of the side wall 111 of the second plate 1132 abuts against the second side surface 1126, so as to correct the shift of the side wall 111 in the X2 direction with respect to the push-pull direction X, the biasing member 132 elastically abuts against the first bracket 110, and the relative shift amount of the first bracket 110 in the X2 direction can be reduced; when the external force disappears, the force applying member 132 is deformed under the action of the elastic force to push the first support 110 to rotate by a corresponding angle along the direction X1 relative to the first support 110, so that the side wall 111 is parallel to the push-pull direction X again, and thus the side wall 111 of the first plate 1131 is spaced and parallel to the first side surface 1125, and the side wall 111 of the second plate 1132 is spaced and parallel to the second side surface 1126, so that a certain gap is maintained between the first support 110 and the second support 120 in the lateral direction, and the first support 110 and the second support 120 can slide smoothly.

By respectively positioning the two adjusting assemblies 130 at two opposite sides of the first support 110, and providing the supporting force to the two opposite sides of the first support 110 by the two adjusting assemblies 130, during the installation and debugging process or the actual use process, a user can selectively adjust the magnitude of the supporting force of one or both of the two adjusting assemblies 130 according to the conditions of the inclination direction, the inclination angle, and the like of the first support 110 relative to the second support 120, correct the relative positions of the first support 110 and the second support 120, so as to correct the side wall 111 of the first support 110 to be substantially parallel to the push-pull direction X, avoid the side directions of the first support 110 and the second support 120 from interfering with each other, reduce the movement resistance between the two, and ensure the smooth sliding of the first support 110 and the second support 120. In actual use, the side wall 111 can be kept substantially parallel to the push-pull direction X by the supporting force of the adjustment assembly 130.

In some embodiments, at least a portion of the force applying member 132 is a resilient structure. As an example, the force applying member 132 may include an elastic end (not shown) and a hard end (not shown) connected to each other, wherein the elastic end is made of a material having elasticity, such as elastic rubber or a spring, and the hard end is made of a rigid material, such as metal, alloy, hard rubber, etc. The flexible end may be connected to the mounting portion 122 and the rigid end may abut the first bracket 110. The elastic end can be in a compressed elastic shape state, the hard end can be tightly abutted to the first support 110 under the action of the elastic end so as to provide a supporting force with a certain size for the first support 110, and the hard end is not easy to deform, so that the contact area between the hard end and the first support 110 can be ensured to be basically kept unchanged, and the friction resistance between the hard end and the side wall 111 can be smaller.

When the push-pull mechanism 100 is subjected to a large external force, such as a holding force or an impact force, the elastic end can be compressed to buffer the external force, so as to reduce the degree of inclination of the first bracket 110 relative to the second bracket 120 caused by the external force, and when the external force is reduced or eliminated, the elastic end can automatically correct the first bracket 110 to the original state under the action of the elastic force of the elastic end, that is, the first bracket 110 is restored to the non-inclined state relative to the second bracket 120. Further, in some embodiments, the entire force applying member 132 may be an elastic body, for example, the force applying member 132 may be an elastic rubber or a spring, etc.

In some embodiments, as shown in fig. 8, the adjusting assembly 130 may include an elastic member 132, and one end of the elastic member 132 may be connected to the force applying member 132 and the other end may be connected to the mounting portion 122. The elastic member 132 may be a spring, a leaf spring, or an elastic rubber. When the force applying element 132 abuts against the first bracket 110, the force applying element 132 can apply an acting force to the elastic element 132, so that the elastic element 132 can be in a compressed elastic deformation state, and the elastic element 132 in the compressed elastic deformation state can provide a reaction to the force applying element 132, so that the force applying element 132 can keep abutting against the first bracket 110, and the force applying element 132 can always provide a certain supporting force to the first bracket 110.

When the first bracket 110 and/or the second bracket 120 are acted by an external force, the elastic member 132 may play a role of buffering to absorb the external force causing the first bracket 110 and the second bracket 120 to be offset relative to the push-pull direction X; when the external force is reduced or eliminated, the first bracket 110 and the second bracket 120 can be restored from the state of being shifted with respect to the push-pull direction X to the non-shifted state by the elastic member 132.

In some embodiments, as shown in fig. 8, the adjusting assembly 130 may include an adjusting member 131, and the adjusting member 131 is disposed on the mounting portion 122 and coupled to the force applying member 132 for adjusting the supporting force. Here, the adjusting member 131 may be directly connected to the force applying member 132, or indirectly connected to the force applying member 132 through an elastic structure or a sliding structure. The adjusting member 131 can provide different magnitudes of the acting force to the force applying member 132, thereby changing the supporting force of the force applying member 132 on the first bracket 110. The elastic member 132 may be disposed between the force applying member 132 and the adjusting member 131, the adjusting member 131 may adjust a compression amount of the elastic member 132, when the compression amount of the elastic member 132 is different, the acting force applied to the force applying member 132 by the elastic member 132 is different, and when the compression amount of the elastic member 132 is larger, the acting force applied to the force applying member 132 by the elastic member 132 is larger.

In some embodiments, the elastic member 132 may be disposed between the force applying member 132 and the adjusting member 131, the elastic member 132 may be in a compressed elastic deformation state under the acting force between the force applying member 132 and the adjusting member 131, and the adjusting member 131 may adjust the compression amount of the elastic member 132.

In some embodiments, the adjusting member 131 is movably disposed on the mounting portion 122 and is connected to a side of the force applying member 132 away from the first bracket 110, and the adjusting member 132 can selectively approach toward the first bracket 110 and provide a supporting force to the force applying member 132 to adjust the supporting force. The adjusting member 131 is slidably disposed on the mounting portion 122, and when the adjusting member 131 approaches the first bracket 110, the adjusting member 131 can continuously press the elastic member 132 to increase the compression amount of the elastic member 132, so that the supporting force of the force applying member 132 on the first bracket 110 is increased, that is, when the adjusting member 131 approaches the first bracket 110, the supporting force can be continuously increased.

In some embodiments, as shown in fig. 9, the second bracket 120 may be provided with a guide channel 124, the guide channel 124 defines a guide direction intersecting the push-pull direction X, the force application member 132 is slidably disposed in the guide channel 124, and the adjustment member 131 is movably disposed along the extension direction of the guide channel 124 and connected to an end of the force application member 132 away from the first bracket 110. By providing the guide channel 124 to guide the force applying member 132, it can be ensured that the force applying member 132 can provide the supporting force to the first bracket 110 along the predetermined direction.

As an example, the guide channel 124 may be disposed on the extension portion 1212, the second bracket 120 includes a guide wall 1241 disposed on the guide channel 124, the number of the guide walls 1241 may be two, the two guide walls 1241 are disposed at an interval and jointly define a guide direction of the guide channel 124, the guide wall 1241 may be a plane, the disposed direction of the guide wall 1241 intersects the push-pull direction X, and since the disposed direction of the guide wall 1241 intersects the push-pull direction X, the sliding direction of the force application member 132 intersects the push-pull direction X, for example, as shown in fig. 9, the disposed direction of the guide wall 1241 may be substantially perpendicular to the push-pull direction X, and the force application member 132 can provide a small supporting force to the side wall 111 to achieve the rectification of the first bracket 110.

In some embodiments, as shown in fig. 9 and 10, one end of the adjusting member 131 may be exposed from the second bracket 120, so that a user can directly operate the adjusting member 131 to adjust the supporting force of the force applying member 132 on the first bracket 110. As an example, the second bracket 120 may be provided with an adjustment hole 1217, the adjustment hole 1217 being in communication with the guide channel 124, the adjustment hole 1217 may be provided laterally of the extension portion 1212, wherein the adjustment hole 1217 may be provided substantially along the length direction Y and through a side of the extension portion 1212 remote from the first bracket 110. Therefore, the space of the frame 1211 can be avoided being occupied, more screen installation positions are vacated, and the high screen occupation ratio is ensured. The adjusting member 131 is disposed through the adjusting hole 1217, one end of the adjusting member 131 far away from the force applying member 132 is exposed through the adjusting hole 1217, the adjusting member 131 can move substantially along the axial direction of the adjusting hole 1217, and the length of the adjusting member 131 extending into the guide channel 124 can be changed to adjust the force applied to the force applying member 132, for example, when the adjusting member 131 continuously extends into the guide channel 124, the adjusting member 131 can continuously press the elastic member 132, so that the supporting force of the force applying member 132 on the sidewall 111 is increased.

As an example, the adjusting element 131 may be an adjusting bolt 1311, the adjusting hole 1217 may be a threaded hole, a nut of the adjusting bolt 1311 may be exposed out of the adjusting hole 1217, and a screw of the adjusting bolt 1311 penetrates through the adjusting hole 1217 and at least partially extends into the guide channel 124 and is connected to the force applying element 132, or is connected to the force applying element 132 through the elastic element 132. The length of the adjusting bolt 1311 extending into the guide passage 124 can be adjusted by turning the adjusting bolt 1311, and the adjusting bolt 1311 continuously increases the force applied to the force applying member 132 while extending into the guide passage 124, so that the supporting force of the force applying member 132 on the side wall 111 increases.

The magnitude of the supporting force of the force application member 132 acting on the side wall 111 can be accurately adjusted by precisely turning the number of turns of the adjustment bolt 1311. After the adjustment is completed, the external thread of the adjusting bolt 1311 can be engaged with the internal thread of the adjusting hole 1217 under the restoring force of the elastic member 132 more tightly, and is not easily loosened, so that the position of the adjusting member 131 is locked, and the force applying member 132 can maintain a predetermined supporting force for the first bracket 110.

In other embodiments, the second bracket 120 may be provided with a locking structure to achieve the locking of the position of the adjusting member 131, for example, as shown in fig. 11, the second bracket 120 may be provided with a plurality of locking portions 127 located in the guide channel 124, the plurality of locking portions 127 may be arranged at intervals substantially along the extending direction of the adjusting groove 126, and the adjusting member 131 may be selectively locked to any one of the locking portions 127. The plurality of locking portions 127 may be equally spaced or unequally spaced, each locking portion 127 has a different preset interval from the sidewall 111, the guide channel 124 may be provided with a corresponding identification scale, each locking portion 127 corresponds to a different identification scale, wherein the identification scale may be used for identifying the magnitude of the supporting force of the force applying member 132 acting on the first bracket 110. When the adjusting member 131 is locked at different locking portions 127, the end of the adjusting member 131 facing the side wall 111 is at different distances from the side wall 111, and the urging force of the adjusting member 131 on the urging member 132 is different in magnitude, so that the supporting force of the urging member 132 on the first bracket 110 is different.

As an example, the locking part 127 may include a locking spring (not shown), and the locking spring may abut against an outer circumference of the adjusting member 131 and provide an elastic abutting force to the adjusting member 131. When the locking elastic sheet is clamped with the adjusting member 131, the locking elastic sheet is in a compressed elastic deformation state, and the adjusting member 131 can be locked at a position corresponding to the guide channel 124 under the action of the elastic abutting force to maintain the acting force on the force applying member 132, so that the supporting force applied by the force applying member 132 to the first bracket 110 is substantially maintained unchanged. Specifically, in this embodiment, two locking elastic pieces may be provided, the two locking elastic pieces are respectively disposed on two opposite sides of the guiding channel 124, the two locking elastic pieces may be respectively connected to two guiding walls 1241 located in the guiding channel 124, correspondingly, the adjusting member 131 may be provided with two engaging portions (not shown in the figure), the two engaging portions are respectively located on two opposite sides of the adjusting member 131, and each engaging portion corresponds to one locking elastic piece to be engaged with the locking elastic piece. The locking part provided by the embodiment is of a spring plate structure, so that the compactness of the spatial layout of parts is effectively improved.

In some embodiments, the locking portion 127 may be a slot structure, and the adjusting member 131 is provided with an elastic protrusion which is matched with the slot structure, and when the adjusting member 131 moves to a position corresponding to the slot structure, the elastic protrusion may be clamped in the slot structure, so as to fix different positions of the adjusting member 131. The locking portion 127 may be a locking mechanism (electromagnetic locking mechanism, electric clamp mechanism) or the like.

In still other embodiments, the adjusting bolt 1311 may not be provided as an adjusting member, as shown in fig. 12, the adjusting assembly 130 may further include a side key 134 and an action rod 135, the side key 134 is slidably connected to the second bracket 120 and can slide along the push-pull direction X, the action rod 135 is provided between the force applying member 132 and the side key 134, the side key 134 has a guiding inclined surface 1341, the guiding inclined surface 1341 is disposed obliquely with respect to the side wall 111, that is, the guiding inclined surface 1341 is disposed obliquely with respect to the push-pull direction X, one end of the action rod 135 abuts against the guiding inclined surface 1341, and the other end is connected to the force applying member 132. As an example, the side key 134 may be disposed on a side of the extension portion 1212 away from the side wall 111, that is, the side key 134 is disposed on a side of the extension portion 133, so as to increase a screen occupation ratio of the electronic device 400. The sliding direction of the side key 134 may be substantially parallel to the push-pull direction X, and the inclination angle of the guiding inclined plane 1341 relative to the side wall 111 may be greater than 90 ° or less than 90 °, which may be specifically adjusted according to actual requirements.

When the side key 134 slides toward the left side (the left side of the observer when the observer looks at fig. 12 from the front) relative to the second bracket 120, the guide slope 1341 can slide relative to the action rod 135 and push the action rod 135 to move toward the force application member 132, so that the action rod 135 continuously presses against the force application member 132, thereby increasing the supporting force of the force application member 132 on the first bracket 110; when the side key 134 slides toward the right side (the right-hand side of the observer when the observer views fig. 12 from the front), the guide slope 1341 can slide relative to the action lever 135 and move away from the action lever 135 to reduce the pressing force of the action lever 135 on the force applying member 132, thereby reducing the supporting force of the force applying member 132 on the first bracket 110. The user can adjust the amount of force by sliding the side key 134.

The force of the force applying member 132 acting on the sidewall 111 can be adjusted by turning the adjusting bolt 1311 or the sliding side key 134, and can be adjusted manually or by machine during or after the assembly of the whole machine.

In some embodiments, as shown in fig. 12, to facilitate the installation of the elastic member 1313, the adjusting assembly 130 may further include a mounting member 136, the mounting member 136 may be slidably disposed on the guide channel 124, the mounting member 136 is used to install the elastic member 1313, one end of the mounting member 136 may abut against or be connected to the adjusting bolt 1311 as shown in fig. 10, or may abut against or be connected to the action rod 135, and the mounting member 136 may press against the elastic member 1313 under the action force of the adjusting bolt 1311 or the action rod 135. As an example, the mounting member 136 may include a sliding portion slidably disposed on the guide channel 124 and capable of abutting against the adjusting bolt 1311 or the action bar 135, and a fixing post protrudingly disposed on an end surface of the sliding portion facing the first bracket 110. The elastic member 1313 is sleeved on the fixing post, one end of the elastic member 1313 abuts against the sliding portion, and the other end is connected to the force applying member 132.

In some embodiments, the force applying member 132 may be arranged to roll relative to the side wall 111 to reduce the friction resistance between the force applying member 132 and the side wall 111, so that the first bracket 110 and the second bracket 120 can slide more smoothly and smoothly. As an example, as shown in fig. 12, the force applying member 132 may include a supporting frame 1321 and a roller 1322, the supporting frame 1321 is disposed on the mounting portion 122, and the roller 1322 is rotatably connected to the supporting frame 1321 and abuts against the first support 110.

In some embodiments, as shown in fig. 12, the force applying member 132 may further include a rotating shaft 1223, the roller 1322 may be a roller, and the roller 1322 is connected to the supporting frame 1321 through the rotating shaft 1223; the first bracket 110 and the second bracket 120 are at least partially overlapped in the thickness direction Z (as shown in fig. 3), and the rotation axis 1223 may be substantially disposed in the thickness direction Z. When the first support 110 slides relative to the second support 120, the roller 1322 can roll along the side wall 111, which effectively reduces the friction resistance when the force applying member 132 moves relative to the first support 110. Additionally, the rollers 1322 may be bearings or balls.

In other embodiments, the biasing member 132 may be slidably disposed with respect to the side wall 111, for example, the roller 1322 described above may be omitted from the biasing member 132, and the end of the support 1321 may directly abut against the side wall 111.

In some embodiments, as shown in fig. 13, the arrangement direction of the force application member 132 may be inclined with respect to the side wall 111, wherein the arrangement direction of the force application member 132 is substantially the same as the direction of the supporting force provided by the force application member 132 to the first bracket 110. As an example, the force applying element 132 may include a rod 1323 and an abutting portion 1324 connected together, the abutting portion 1324 abuts against the sidewall 111, the abutting portion 1324 may include a supporting frame 1321 and a roller 1322 as shown in fig. 10, the rod 1323 is disposed obliquely with respect to the sidewall 111, that is, an axis of the rod 1323 is disposed obliquely with respect to the sidewall 111, and an included angle formed between the rod 1323 and the sidewall 111 may be smaller than or equal to 90 °. By arranging the lever 1323 obliquely with respect to the side wall 111, since the direction of the supporting force of the force application member 132 substantially coincides with the arrangement direction of the lever 1323, the supporting force can be inclined with respect to the side wall 111, and the force mainly used for correcting the first bracket 110 is a component force of the supporting force in an oblique direction perpendicular to the push-pull direction X. When the first bracket 110 and the second bracket 120 are subjected to an external force such as an impact force or a holding force, the oblique component of the force applying member 132 acting on the sidewall 111 is small, so that a large degree of impact is not caused to the lateral direction of the first bracket 110, and the relative inclination between the first bracket 110 and the second bracket 120 is reduced or avoided, thereby ensuring the reliability of the movement.

In some embodiments, as shown in fig. 14, one end of the rod 1323 away from the abutting portion 1324 is pivotally connected to the mounting portion 122, the adjusting component 130 includes a driving portion 137, the driving portion 137 is in transmission fit with the force applying member 132, and the driving portion 137 can drive the force applying member 132 to rotate relative to the mounting portion 122, so as to adjust the inclination of the rod 1323 relative to the sidewall 111. The driving part 137 may include one of a driving motor, a driving cylinder, and a driving cylinder. For example, the driving portion 137 may include a driving cylinder, a cylinder body of the driving cylinder may be fixed to the mounting portion 122, and a telescopic rod of the driving cylinder is connected to the rod body 1323, and the telescopic rod of the driving cylinder can drive the force applying member 132 to rotate relative to the mounting portion 122 during the telescopic process. For example, the telescopic direction of the driving cylinder may be consistent with the push-pull direction X, and the telescopic rod of the driving cylinder may be hinged to the rod body 1323. The rod body 1323 can be accurately rotated to a specific angle by adjusting the telescopic length of the telescopic rod of the driving cylinder, and when the telescopic length of the telescopic rod of the driving cylinder is kept unchanged, the inclination angle of the rod body 1323 relative to the side wall 111 (the acute angle formed between the rod body 1323 and the side wall 111) can be kept unchanged. When the telescopic rod of the driving cylinder is extended, the inclination angle of the rod 1323 with respect to the side wall 111 can be reduced, and when the inclination angle of the rod 1323 with respect to the side wall 111 is reduced, the component force of the support force in the diagonal direction Y is smaller, that is, the component force of the support force in the diagonal direction perpendicular to the push-pull direction X is smaller. In addition, the driving part 137 may include a nut and an adjusting screw, the nut may be fixed to the mounting part 122, the adjusting screw may be disposed along the push-pull direction X, one end of the adjusting screw is threaded to the nut, and the other end of the adjusting screw is connected to the rod body 1323, and the adjusting screw may be manually driven to select the adjusting screw, so that the adjusting screw adjusts the rotation angle of the rod body 1323 along the push-pull direction X.
