[0029] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present disclosure. In the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0030] In the embodiments of the present disclosure, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, unless otherwise specified, "multiple" means two or more.

[0031] In addition, in the embodiments of the present disclosure, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to changes in the orientation of the components in the drawings.

[0032] In the embodiments of the present disclosure, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integrated connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0033] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise," "include," etc. used herein indicate the presence of features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0034] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0035] When expressions such as "at least one of A, B, and C, etc." are used, they should generally be interpreted in accordance with the meaning commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0036] The embodiments of the present disclosure provide a connection device and an electronic device. Before introducing the technical solutions provided by the embodiments of the present disclosure, the related technologies involved in the present disclosure are first described.

[0037] Openable devices (such as laptops and mobile phones) use a connector to connect the two parts of the device. The connector provides support and torque to enable the device to be folded or unfolded to varying degrees. However, current connectors are not convenient to open and close, resulting in a poor user experience.

[0038] For example, with the development of thinner and lighter notebooks and users' increasing demands for notebook user experience, especially the current application of open-lid startup technology, the screen can be opened with one hand has become an indispensable highlight in notebook design and development.

[0039] The inventor of this application found that with the design of thin and light notebooks, the weight of the system and the screen are getting closer and closer, and it is difficult to open the notebook with one hand when the footrest is located close to the edge of the notebook. Figure 1 Positioning the foot pads away from the rotation axis will reduce the system's center of gravity arm, lower the system's weight torque, and increase the difficulty of one-handed opening.

[0040] To achieve one-handed opening, the torque of the connecting device must be less than the gravitational torque of the system when the screen is opened. At the same time, since the touch screen operation function of the screen is also an indispensable function of a thin and high-end notebook, if touch screen operation is to be achieved, the connecting device is required to have sufficient torque to keep the screen from shaking when the user performs touch screen operation. Therefore, taking into account the above two requirements has become an urgent problem to be solved. In addition, during the process of opening and closing the screen, due to the weight of the screen itself, the center of gravity of the screen will change with the change of the opening and closing angle. When the center of gravity reaches the target position, it is easy to cause the screen to fall, thereby affecting the user experience.

[0041] An embodiment of the present disclosure provides a connecting device, comprising: a rotating shaft, a first end of the rotating shaft being used for fixedly connecting to a first target part; a fixing frame being arranged at a second end of the rotating shaft, the fixing frame being used for rotatably connecting the second target part to the rotating shaft; a bushing assembly being respectively connected to the fixing frame and the rotating shaft, the bushing assembly being used for providing a first resistance during the rotation of the fixing frame relative to the rotating shaft, so that the first target part can be at different opening and closing angles relative to the second target part; a target assembly being respectively connected to the fixing frame and the rotating shaft, when the opening and closing angle is within a target range, the torque provided by the target assembly is zero, and when the opening and closing angle is greater than a target threshold, the target assembly is used for increasing or decreasing the first resistance according to the opening and closing angle.

[0042] The following will be passed Figures 2 to 8 The connection device of the disclosed embodiment is described in detail.

[0043] Figure 2 One of the structural diagrams of the connecting device according to an embodiment of the present disclosure is schematically shown.

[0044] like Figure 2 As shown, the connecting device 100 of this embodiment includes: a rotating shaft 110 , a fixing bracket 120 , a sleeve assembly 130 and a target assembly 140 .

[0045] The rotating shaft 110 , wherein the first end of the rotating shaft 110 can be used to be fixedly connected to the first target component.

[0046] Exemplarily, the rotating shaft 110 may be a solid shaft, or a hollow shaft, etc. As an example, when the rotating shaft 110 is a hollow shaft, the hollow shaft may be used to pass a cable from the first target component to the second target component.

[0047] The first target part can be a body with certain functions, for example, a display screen with a display function, a keyboard with an input function, or a charging part of an earphone compartment with a charging function.

[0048] The first target member can be fixedly connected to the first end of the rotating shaft 110, that is, the first target member and the rotating shaft 110 are connected as a whole, and the movement state of the first target member can be synchronized with the movement state of the rotating shaft 110. For example, the first end of the rotating shaft 110 can be flat, and the keyboard can be fixed to the first end of the rotating shaft 110 by bolts.

[0049] The fixing bracket 120 may be disposed at the second end of the rotating shaft 110 , and the fixing bracket 120 may be used to rotatably connect the second target component to the rotating shaft 110 .

[0050] Exemplarily, the second target part may also be a body with certain functions. For example, a display screen with a display function, a keyboard with an input function, a part of an earphone compartment cover with a shielding function, etc. The second target part may have the same function as the first target part, or may have a different function. For example, in the case where the first target part and the second target part have the same function, the first target part and the second target part may both be display screens with a display function, such as a foldable screen mobile phone. In the case where the first target part and the second target part have different functions, the first target part may be a keyboard with an input function, and the second target part may be a display screen with a display function, such as a laptop computer.

[0051] The fixing frame 120 can be rotatably connected to the second end of the rotating shaft 110, and the second target member can be fixedly connected to the fixing frame 120. When the fixing frame 120 rotates relative to the rotating shaft 110, the second target member can rotate synchronously with the fixing frame 120 relative to the rotating shaft 110. Because the first target member is fixed to the rotating shaft 110, when the second target member is pushed to rotate, the second target member drives the fixing frame 120 to rotate synchronously, thereby enabling the second target member to rotate relative to the first target member.

[0052] The sleeve assembly 130 is connected to the fixing frame 120 and the rotating shaft 110 respectively. The sleeve assembly 130 is used to provide a first resistance during the rotation of the fixing frame 120 relative to the rotating shaft 110, so that the first target part can be at different opening and closing angles relative to the second target part.

[0053] For example, the sleeve assembly 130 can provide a first resistance by generating different frictional forces through different degrees of interference fit between parts, i.e., different fitting tolerances. This frictional force can serve as the first resistance to rotation. The sleeve assembly 130 can generate a damping effect when the second target part rotates relative to the first target part, allowing the first target part to be in a closed state or an extended state relative to the second target part.

[0054] In some embodiments, the first resistance generated by the sleeve assembly 130 may be constant. In other embodiments, the first resistance generated by the sleeve assembly 130 may be variable. For example, during the process of opening the first target part relative to the second target part, the first resistance may decrease, which can achieve the effect of one-handed opening; during the process of closing the first target part relative to the second target part, the first resistance may increase, which can prevent the screen from falling during the closing process. Here, the sleeve assembly 130 may have the effect of opening lightly and closing heavily. That is, during the process of opening the connecting device 100, a smaller force can be used to open it. During the process of closing it, a larger force can be used to close it.

[0055] The connecting device 100 can connect the first target part and the second target part. The first target part and the second target part can be relatively rotated through the connecting device 100, so that the first target part and the second target part can be switched between a closed state and an expanded state through the connecting device 100.

[0056] Here, the closed state may be a state in which the first target part and the second target part are closed together, which can be understood as the angle between the first target part and the second target part being 0. The expanded state may be a state in which a certain angle is formed between the first target part and the second target part, which can also be understood as the expanded state being a state in which a non-closed state is formed, and the expanded state can be considered when the angle between the first target part and the second target part is not 0.

[0057] The target component 140 can be connected to the fixed frame 120 and the rotating shaft 110 respectively. When the opening and closing angle is within the target range, the torque provided by the target component 140 is zero. When the opening and closing angle is greater than the target threshold, the target component 140 is used to increase or decrease the first resistance according to the opening and closing angle.

[0058] Exemplarily, one end of the target assembly 140 can be connected to the fixed frame 120, and the other end of the target assembly 140 can be connected to the rotating shaft 110. The target assembly 140 can be capable of providing a variable force to assist in opening and closing according to the different opening and closing angles of the first target part relative to the second target part. When the angle at which the second target part is opened or closed relative to the first target part is within the target interval, the torque generated by the target assembly 140 is zero. When the second target part is opened or closed relative to the first target part within the target interval, it is necessary to overcome the first resistance provided by the bushing assembly 130 to achieve adjustment of different opening and closing angles. When the angle at which the second target part is opened or closed relative to the first target part is greater than the target threshold, the target assembly 140 generates additional resistance or power. When the angle at which the second target part is opened or closed relative to the first target part is greater than the target threshold, if the target component 140 generates additional power, it is necessary to overcome the first resistance while having the additional power to help reduce the force required to overcome the first resistance, thereby reducing the force of the switch to achieve adjustment of different opening and closing angles; if the target component 140 generates additional resistance, it is necessary to overcome the first resistance while also overcoming the additional resistance, thereby increasing the force of the switch to achieve adjustment of different opening and closing angles.

[0059] The target interval and target threshold do not overlap. The target interval and target threshold can have continuous or discontinuous values. For example, the target interval can be 0︒-90︒, 0︒-120︒, or 0︒-135︒. When the target interval is 0︒-90︒, the target threshold can be, for example, 91︒, 92︒, 93︒, etc. In other words, the target threshold can be any value greater than 90︒ to form a continuous value with the target interval. The target threshold can also be 120︒ to form a discontinuous value with the target interval. In the present disclosed embodiments, the target values ​​and target thresholds are not specifically limited and can be set according to the actual application.

[0060] For the opening and closing device using the connecting device 100, the influence of the target component 140 on the connecting device 100 acts on the opening and closing process, and the opening and closing process corresponds to a target interval composed of multiple continuous different opening and closing angle values. When the opening and closing angle is a certain value, the situation of the force required for opening and closing is not involved. Because once a force acts on the rotating body of the opening and closing device, if the force is greater than the resistance generated by the shaft, rotation can be generated. At this time, the opening and closing angle will inevitably change. The change in the opening and closing angle corresponds to the target interval, not a specific angle.

[0061] Compared to the related art, where torsion springs provide zero torque at a certain threshold, the target assembly 140 designed in this application can provide zero torque within a certain target range, without affecting the original hinge closure design. For example, the related art uses a torsion spring to generate force between degrees greater than zero and less than 90 degrees to facilitate opening. At 90 degrees, the torsion spring has zero torque. However, at degrees less than 90 degrees and greater than zero, the torsion spring will inevitably have a side effect, making closing between degrees less than 90 degrees and greater than zero more difficult, requiring more force to achieve closure. Therefore, compared to the target assembly designed in this application, which can provide zero torque within the target range of 0-90 degrees, the design in the related art requires more force to close. For example, when the connecting device 100 is applied to a laptop computer, the first target part is a keyboard with an input target, and the second target part is a display screen with a display target, when the display screen is opened or closed at 0-90 degrees (target range) relative to the keyboard, the sleeve assembly 130 works and the target assembly 140 does not work. The target assembly 140 does not interfere with the operation of the sleeve assembly 130, so that within the target range, the movement of the rotating shaft 110 is smoother and more controllable, reducing operational instability caused by torque changes; at the same time, it can also reduce unnecessary friction and wear between structural components and extend the service life of the connecting device.

[0062] When the display screen is opened relative to the keyboard at an angle greater than 90 degrees (target threshold), the shaft sleeve can support the screen, but as the opening angle increases, the torque of the shaft increases. At this time, the target component 140 can increase the torque of the shaft to achieve stable support for the screen, and even if the user performs touch-screen operations, the screen is not likely to fall off.

[0063] When the display screen is closed relative to the keyboard at an angle greater than 90 degrees (target threshold), the sleeve can support the screen. At this time, the target component 140 can generate additional power to help reduce the force required to overcome the first resistance, so that the user can use relatively small force to close the screen from greater than 90 degrees to 90 degrees.

[0064] It can be understood that by setting the target component 140 to assist the shaft sleeve component 130 in realizing the opening and closing of the second target part relative to the first target part, when the opening and closing angle is within the target range, the target component 140 provides zero torque and does not interfere with the first resistance generated by the rotation of the shaft sleeve component 130, and can achieve better opening and closing on the basis of the shaft sleeve component 130; when the opening and closing angle is greater than the target threshold, the target component 140 can generate a force to increase the first resistance to provide stable support for the second target part, so that the second target part is not easy to fall, or the target component 140 can generate a force to reduce the first resistance to reduce the force of opening or closing the second target part, which is more conducive to the opening and closing between the second target part and the first target part.

[0065] In some embodiments, during the opening of the first target part relative to the second target part, the sleeve assembly 130 can generate auxiliary power to reduce the first resistance; during the closing of the first target part relative to the second target part, the sleeve assembly 130 can generate auxiliary resistance to increase the first resistance.

[0066] For example, the sleeve assembly 130 itself can have the effect of opening lightly and closing heavily. The sleeve assembly 130 itself can provide a first resistance, and the sleeve assembly 130 can change the size of the first resistance according to different opening and closing states. In the process of the second target part opening relative to the first target part, the sleeve assembly 130 can generate auxiliary power to reduce the force required to overcome the first resistance, thereby achieving light opening. In the process of the second target part opening and closing relative to the first target part, the sleeve assembly 130 can generate auxiliary resistance to increase the force required to overcome the resistance, thereby achieving heavy closing.

[0067] The target component 140 can further affect the opening and closing force based on the opening and closing weight produced by the sleeve component 130 when the opening and closing angle is greater than the target threshold, which is more conducive to achieving opening and closing.

[0068] For example, when the connecting device 100 is applied to a laptop computer, and the first target part is a keyboard with an input target, and the second target part is a display screen with a display target, since the shaft sleeve assembly itself has the effect of opening lightly and closing heavy, when the display screen is opened relative to the keyboard in the range of 0-90 degrees (target range), the shaft torque can be less than the gravitational torque of the screen weight, which means that the friction force generated by the shaft when the screen is opened can not only overcome the gravity of the screen but also be relatively small. In this way, the torque required to rotate the screen will also be relatively small, and the user can smoothly lift the screen with one hand, that is, one-handed opening can be achieved. When the display screen is closed relative to the keyboard in the range of 90-0 degrees, the shaft torque can be greater than the gravitational torque of the screen weight, which means that the friction force generated by the shaft when the screen is closed can not only overcome the gravity of the screen but also be relatively large. In this way, the torque required to rotate the screen will also be relatively large. The support with a large torque can resist the gravity of the screen, which can prevent the screen from falling.

[0069] Therefore, for a laptop computer using the connection device 100 , when the sleeve assembly 130 can meet user needs within the target range, the torque generated by the added target assembly 140 is zero and is unlikely to affect the opening and closing force within the target range.

[0070] When the display screen is opened relative to the keyboard at an angle greater than 90 degrees (target threshold), the shaft sleeve can support the screen, but as the opening angle increases, the torque of the shaft increases. At this time, the target component 140 can increase the torque of the shaft to achieve stable support for the screen, and even if the user performs touch-screen operations, the screen is not likely to fall off.

[0071] When the display screen is closed relative to the keyboard at an angle greater than 90 degrees (target threshold), the sleeve can support the screen. At this time, the target component 140 can generate additional power to help reduce the force required to overcome the first resistance, so that the user can use relatively small force to close the screen from greater than 90 degrees to 90 degrees.

[0072] In some embodiments, the minimum value of the target interval is 0, the maximum value of the target interval is greater than 0 and less than 360; and the target threshold is the same as the maximum value of the target interval.

[0073] For example, the target interval and the target threshold can be continuous values. The maximum value of the target interval can be set based on the range of rotation of the second target part relative to the first target part. For example, if the range of rotation of the second target part relative to the first target part is 0-180°, the target interval can be 0-90°, and the target threshold can be 91°; the target threshold can be 110°; the target interval can also be 0-115°, and the target threshold can be 116°; the target interval can also be 0-120°, and the target threshold can be 125°; the target interval can also be 0-135°, and the target threshold can be 140°. If the second target member rotates within a range of 0-360° relative to the first target member, the target interval can be 0-90°, and the target threshold can be 91°; the target threshold can be 110°; the target interval can also be 0-115°, and the target threshold can be 116°; the target interval can also be 0-120°, and the target threshold can be 125°; the target interval can also be 0-135°, and the target threshold can be 145°; the target interval can also be 0-180°, and the target threshold can be 181°. The present disclosure does not impose specific limitations on the setting of the target interval and target threshold, and they can be set within a known range based on actual application conditions.

[0074] For example, when the opening and closing angle of the second target part relative to the first target part is between 0° and 90° and increases, the torque provided by the target assembly 140 is zero, without affecting the first resistance originally generated by the sleeve assembly 130, allowing the second target part to open more easily relative to the first target part. When the opening angle of the second target part relative to the first target part exceeds 90°, and the opening angle of the second target part relative to the first target part continues to increase, the target assembly 140 provides additional resistance, thereby increasing the first resistance to the rotation of the second target part relative to the first target part. This increased first resistance not only prevents the screen from shaking when the user touches the display, but also effectively offsets the weight of the display at larger opening angles, preventing it from falling.

[0075] When the closing angle of the second target member relative to the first target member exceeds 90°, the target assembly 140 can provide a force to reduce the first resistance to the rotation of the second target member relative to the first target member, making it easier for the second target member to close relative to the first target member. When the closing angle of the second target member relative to the first target member is between 0° and 90° and increases, the closing angle of the second target member relative to the first target member continues to decrease, and the torque provided by the target assembly 140 becomes zero, without affecting the first resistance originally generated by the sleeve assembly 130.

[0076] In some embodiments, during the rotation of the target component 140 with the fixing frame 120, when the opening and closing angle is within the target range, the end of the target component 140 away from the fixing frame 120 is freely set; when the opening and closing angle is greater than the target threshold, the end of the target component 140 away from the fixing frame 120 is limited, and the target component 140 generates torque as the fixing frame 120 rotates.

[0077] For example, when the opening and closing angle of the second target part relative to the first target part is within the target range, one end of the target assembly 140 can rotate synchronously with the fixed frame 120, and the other end of the target assembly 140 can be in a free state, that is, the entire target assembly 140 can rotate synchronously with the fixed frame 120, and no force is generated during the synchronous rotation. Therefore, the torque provided by the target assembly 140 is zero. When the opening and closing angle of the second target part relative to the first target part is greater than the target threshold, one end of the target assembly 140 can rotate synchronously with the fixed frame 120, and the other end of the target assembly 140 can be limited, that is, during the synchronous rotation of one end of the target assembly 140 with the fixed frame 120, the other end of the target assembly 140 cannot achieve synchronous rotation, thereby causing the target assembly 140 to generate a certain torque. When the torque generating the torque of the target assembly 140 is connected to the torque generating the first resistance of the shaft sleeve assembly 130, the torque can be used as a power to reduce the first resistance. In the case where the torque generating the torsional force in the target assembly 140 is opposite to the torque generating the first resistance force in the sleeve assembly 130 , the torsional force can be used as a driving force to increase the first resistance force.

[0078] It should be noted that the torque generated by the target assembly 140 can be constant, and the magnitude of the torque remains unchanged at different opening and closing angles. The torque generated by the target assembly 140 can also be variable, and the magnitude of the torque varies at different opening and closing angles.

[0079] Figure 3 The second structural diagram of the connecting device according to the embodiment of the present disclosure is schematically shown. Figure 4 The third structural diagram of the connecting device according to the embodiment of the present disclosure is schematically shown.

[0080] like Figure 3 As shown, in one implementation, the target component 140 includes an elastic member 141 .

[0081] The first end of the elastic member 141 can be connected to the fixing frame 120, and the second end of the elastic member 141 can be inserted into the limiting hole 151 arranged circumferentially along the rotating shaft 110. When the opening and closing angle is within the target range, the first end of the elastic member 141 can rotate synchronously with the fixing frame 120, and the second end of the elastic member 141 can slide along the arrangement direction of the limiting hole 151.

[0082] For example, the elastic member 141 may be a deformable entity, which can generate a restoring force after deformation, and the restoring force can serve as an auxiliary torsion force. For example, the elastic member 141 may be a tension spring, a spring, or the like.

[0083] The limiting holes 151 may be holes arranged along the circumference of the rotating shaft 110. The length of the limiting holes 151 may be set accordingly according to the value range of the target interval.

[0084] Reference Figure 3 and Figure 4 The first end of the elastic member 141 can be connected to the fixing frame 120. When the fixing frame 120 rotates relative to the rotating shaft 110, the first end of the elastic member 141 can rotate synchronously with the fixing frame 120 relative to the rotating shaft 110. The second end of the elastic member 141 can extend into the limiting hole 151, and the second end of the elastic member 141 can be in different states as the opening and closing angle changes.

[0085] When the opening and closing angle is within the target range, the second end of the elastic member 141 can be free within the limiting hole 151, meaning that the entire elastic member 141 can rotate synchronously with the fixing frame 120, resulting in zero torque. When the opening and closing angle is greater than the first threshold, the second end of the elastic member 141 is blocked by the first side surface of the limiting hole 151, meaning that the second end of the elastic member 141 is restrained. As the first end of the elastic member 141 rotates synchronously with the fixing frame 120, the second end of the elastic member 141 cannot rotate synchronously with the fixing frame 120, causing the elastic member 141 to deform, thereby generating a restoring force. When the direction of the torque generated by the deformation of the elastic member 141 is the same as that generated by the shaft sleeve assembly 130, the restoring force is superimposed on the first resistance, thereby increasing the first resistance. When the direction of the torque generated by the deformation of the elastic member 141 is opposite to that generated by the shaft sleeve assembly 130, the restoring force is superimposed on the first resistance, thereby decreasing the first resistance.

[0086] It is understood that by providing retaining holes 151 to adapt to the target range, elastic member 141 can rotate synchronously with mounting bracket 120 without deformation, thereby achieving zero impact of target assembly 140 on sleeve assembly 130. When the rotation angle exceeds a first threshold, retaining holes 151 can limit the second end of elastic member 141, causing elastic member 141 to deform and provide a force as the first end of elastic member 141 rotates with mounting bracket 120. Therefore, the additional torque required for different opening and closing angles can be adjusted to achieve better opening and closing, improving the user experience.

[0087] In some embodiments, when the opening and closing angle is greater than the target threshold and increases, the first end of the elastic member 141 can rotate synchronously with the fixing frame 120, the second end of the elastic member 141 can be fixed, and the rotational torque of the elastic member 141 increases to provide a second resistance.

[0088] When the opening and closing angle is greater than the target threshold and decreases, the first end of the elastic member 141 can rotate synchronously with the fixing frame 120, the second end of the elastic member 141 can be fixed, and the torque generated by the elastic member 141 can be opposite to the torque generated by the sleeve assembly 130 to provide a force, and the rotational torque of the elastic member 141 is reduced.

[0089] For example, when the second target member is deployed at an angle greater than a first threshold relative to the first target member and the angle increases, the second end of the elastic member 141 can be blocked by the first side surface of the limiting hole 151, that is, the second end of the elastic member 141 can be limited. As the first end of the elastic member 141 rotates synchronously with the fixing frame 120, the second end of the elastic member 141 cannot rotate synchronously with the fixing frame 120, causing the elastic member 141 to deform, thereby generating a restoring force, which is the second resistance. Because the direction of the rotational torque generated by the deformation of the elastic member 141 is the same as the torque generated by the shaft sleeve assembly 130, the second resistance is superimposed on the first resistance to increase the first resistance. As the deformation increases (i.e., the opening angle becomes larger and larger), the rotational torque increases, and the second resistance also becomes larger and larger. When the second target part is unfolded at an angle greater than the first threshold relative to the first target part and the angle decreases, the second end of the elastic part 141 can continue to be blocked by the first side surface of the limiting hole 151, that is, the second end of the elastic part 141 is limited. As the first end of the elastic part 141 rotates synchronously with the fixing frame 120, the deformation of the elastic part 141 gradually decreases, and the second end of the elastic part 141 cannot rotate synchronously with the first end of the fixing frame 120. At this time, the direction of the torque generated by the deformation of the elastic part 141 is opposite to the torque generated by the shaft sleeve assembly 130. The force generated by the deformation recovery of the elastic part 141 is superimposed on the first resistance to reduce the first resistance. And as the deformation decreases (that is, the closing angle becomes smaller and smaller), the rotational torque decreases and the force also becomes smaller and smaller.

[0090] For example, in the case where the first target member is a keyboard and the second target member is a display screen. If the display screen is opened at an angle greater than 90 degrees relative to the keyboard, the elastic member 141 deforms, and the direction of the torque generated is the same as the direction of the torque generated by the shaft sleeve assembly 130. This can increase the first resistance generated by the shaft sleeve assembly 130. As the opening angle increases, the rotational torque increases, the second resistance increases, and the overall resistance of the connecting device 100 increases. Therefore, when the display screen is opened at an angle greater than 90 degrees, the target assembly 140 can further provide a second resistance to better support the display screen. If the display screen is closed at an angle greater than 90 degrees and less than 180 degrees relative to the keyboard, as the closing angle decreases, the deformation of the elastic member 141 also decreases. As the closing angle decreases, the rotational torque decreases, and the applied force decreases. However, the direction of the torque generated by the elastic member 141 is opposite to that of the torque generated by the shaft sleeve assembly 130. Therefore, the first resistance generated by the shaft sleeve assembly 130 can be reduced, facilitating the closing operation between the display screen and the keyboard.

[0091] It is understandable that as the opening angle increases, the rotational torque of the elastic member 141 becomes increasingly greater, effectively offsetting the falling torque of the display screen weight, so the torque of the entire rotating shaft 110 increases. On the one hand, it can support the display screen for large-angle touch screen operation, and on the other hand, it can also prevent the display screen from falling.

[0092] In some embodiments, the connecting device 100 of this embodiment further includes: a fixing plate 150 .

[0093] The fixing plate 150 can be detachably connected to the rotating shaft 110. The fixing plate 150 can be located on the side of the elastic member 141 away from the fixing frame 120. The side of the fixing plate 150 facing the fixing frame 120 has a limiting hole 151, and the fixing plate 150 can rotate synchronously with the rotating shaft 110.

[0094] Exemplarily, the fixing plate 150 can be coaxially mounted on the rotating shaft 110 and can be detachably connected to the rotating shaft 110. The fixing plate 150 can be provided with limiting holes 151 arranged along the circumference of the rotating shaft 110. When in use, the fixing plate 150 can be fixed on the rotating shaft 110, and the second end of the elastic member 141 can be kept inserted into the limiting hole 151 on the fixing plate 150. By rotating the second target member, the first end of the elastic member 141 can rotate synchronously with the second target member, and the second end of the elastic member 141 can slide in the limiting hole 151. When maintaining the connecting device 100, the fixing plate 150 can be separated from the rotating shaft 110 to perform maintenance on the connecting device 100.

[0095] It is understandable that the detachable fixing piece 150 can not only provide a force for the target component 140 to open and close at a suitable opening and closing angle, but also facilitate the subsequent maintenance work of the connecting device 100 by the staff.

[0096] Figure 5 A fourth structural diagram of the connecting device according to an embodiment of the present disclosure is schematically shown.

[0097] In some embodiments, as Figure 4 and Figure 5 As shown, the connecting device 100 of this embodiment further includes an anti-slip component 170 .

[0098] The fixing plate 150 may have a first fixing hole 152 connected to the limiting hole 151, the rotating shaft 110 passes through the first fixing hole 152, the rotating shaft 110 may have a first stop surface 110A, and the anti-slip component 170 is detachably arranged on the side of the fixing plate 150 away from the fixing frame 120, and the anti-slip component 170 is used to press the fixing plate 150 tightly against the first stop surface 110A.

[0099] For example, the anti-slip member can form a barrier on a side of the fixing plate away from the first stop surface, and cooperate with the first stop surface to clamp the fixing plate. For example, the anti-slip member can be a block fixedly connected to the rotating shaft, or a block detachably connected to the rotating shaft, for example, with an interference fit on the rotating shaft.

[0100] The first fixing hole 152 may be circular, square, or oval. The embodiment of the present disclosure does not specifically limit the shape of the first fixing hole 152.

[0101] The fixing plate 150 can be located on a side of the target assembly 140 away from the fixing frame 120. A first fixing hole 152 can be defined at the center of the fixing plate 150, through which the rotating shaft 110 passes. The first fixing hole 152 can be connected to the limiting hole 151. The second end of the rotating shaft 110 can be arranged in a stepped manner, thereby forming a first stop surface 110A. The diameter of the second end of the rotating shaft 110 is smaller than the diameter of the first end of the rotating shaft 110. The diameter of the first fixing hole 152 is larger than the diameter of the second end of the rotating shaft 110 and smaller than the diameter of the first end of the rotating shaft 110. When the fixing plate 150 is passed through the second end of the rotating shaft 110, the anti-slip component 170 forms a barrier on the side of the fixing plate 150 away from the fixing frame 120. The anti-slip component 170 presses the side of the fixing plate 150 close to the fixing frame 120 against the first blocking surface 110A, making it difficult for the fixing plate 150 to fall off the rotating shaft 110, thereby realizing a detachable connection of the fixing plate 150 on the rotating shaft 110.

[0102] In other embodiments, the limiting hole 151 may not be connected to the first fixing hole 152 .

[0103] In some embodiments, the first fixing hole 152 may have at least one first horizontal surface 1521 , and the rotating shaft 110 may have at least one second horizontal surface 110B. The first horizontal surface 1521 may fit with the second horizontal surface 110B so that the fixing plate 150 rotates synchronously with the rotating shaft 110 .

[0104] For example, first horizontal surfaces 1521 may be provided on opposite side walls of the first fixing hole 152, i.e., the first fixing hole 152 is oval-shaped. Second horizontal surfaces 110B may be provided on opposite sides of the rotating shaft 110. When the fixing plate 150 is fixedly connected to the rotating shaft 110, the two first horizontal surfaces 1521 of the first fixing hole 152 may respectively mate with the two second horizontal surfaces 110B on the rotating shaft 110, thereby limiting the fixing plate 150 on the rotating shaft 110 and making it difficult for the fixing plate 150 to move along the circumference of the rotating shaft 110. This ensures that after each use of the connecting device 100, the position between the second end of the elastic member 141 and the limiting hole 151 remains constant.

[0105] In other embodiments, the first fixing hole 152 can be configured to have a first horizontal surface 1521, and the rotating shaft 110 can also be configured to have a corresponding second horizontal surface 110B, so that the first horizontal surface 1521 and the second horizontal surface 110B are aligned, so that the fixing plate 150 is not easily displaced along the circumference of the rotating shaft 110 on the rotating shaft 110. The present embodiment does not specifically limit the number of first horizontal surfaces 1521 and second horizontal surfaces 110B, and can be set as needed.

[0106] In some embodiments, the anti-dropping member 170 includes a fixing nut 171 , which can be threadedly assembled with the rotating shaft 110 .

[0107] It is understood that by turning the fixing nut 171 closer to the fixing plate 150, the fixing nut 171 can fix the fixing plate 150 against the first stop surface 110A. By turning the fixing nut 171 away from the fixing plate 150, the fixing plate 150 can be separated from the rotating shaft 110, which is convenient and quick to operate.

[0108] In other embodiments, the anti-slip member 170 may further include a limit block having a through hole formed thereon, and the through hole is interference fit with the second end of the rotating shaft 110 to form a barrier on the side of the fixing plate 150 away from the fixing frame 120.

[0109] In some embodiments, continue to refer to Figure 3The connection device 100 of the embodiment of the present disclosure may further include: at least one buffer sheet 160. The at least one buffer sheet 160 may be located between the fixing nut 171 and the fixing sheet 150. The buffer sheet 160 has a second fixing hole 161, and the rotating shaft 110 passes through the second fixing hole 161.

[0110] For example, multiple buffer sheets 160 can be sequentially positioned between the fixing nut 171 and the fixing plate 150. The buffer sheet 160 has a second fixing hole 161 through which the rotating shaft 110 passes. The second fixing hole 161 can be oval-shaped to prevent the buffer sheet 160 from circumferentially moving on the rotating shaft 110. Tightening the fixing nut 171 clamps the multiple buffer sheets 160 between the fixing plate 150 and the fixing nut 171, further securing the fixing plate 150 to the rotating shaft 110.

[0111] Figure 6A The fifth structural diagram of the connecting device according to the embodiment of the present disclosure is schematically shown.

[0112] In one possible implementation, referring to Figure 3 and Figure 6A The elastic member 141 includes a torsion spring 1411 .

[0113] The torsion spring 1411 can be coaxially sleeved on the rotating shaft 110 . The fixing frame 120 has a third fixing hole 121 . The first end of the torsion spring 1411 can be inserted into the third fixing hole 121 , and the second end of the torsion spring 1411 can be inserted into the limiting hole 151 .

[0114] For example, the elastic member 141 may be a torsion spring 1411. The torsion spring 1411 may be deformed by rotation or twisting.

[0115] A third fixing hole 121 is defined on the side of the fixing frame 120 facing the fixing plate 150. The first end of the torsion spring 1411 can be inserted into the third fixing hole 121. The second end of the torsion spring 1411 can be inserted into the retaining hole 151 in the fixing plate 150. When the fixing frame 120 rotates relative to the rotating shaft 110, the first end of the torsion spring 1411 can rotate with the fixing frame 120. Within the target range, the second end of the torsion spring 1411 can move along the direction of the retaining hole 151. In this case, the torsion spring 1411 moves synchronously with the fixing frame 120. When the rotation angle of the fixing frame 120 exceeds the target threshold, the second end of the torsion spring 1411 is blocked by the first side surface of the retaining hole 151. The first end of the torsion spring 1411 continues to rotate with the fixing frame 120, and the second end of the torsion spring 1411 is retained. At this point, the torsion spring 1411 deforms, thereby generating a restoring force. When the direction of the torque generated by the deformation of the torsion spring 1411 is the same as the torque generated by the sleeve assembly 130, the restoring force is superimposed on the first resistance to increase the first resistance; when the direction of the torque generated by the deformation of the torsion spring 1411 is opposite to the torque generated by the sleeve assembly 130, the restoring force is superimposed on the first resistance to reduce the first resistance. Figure 6B The sixth structural diagram of the connecting device according to an embodiment of the present disclosure is schematically shown.

[0116] In another possible implementation, referring to Figure 3 and Figure 6B The elastic member 141 includes an elastic sheet 1412 .

[0117] The rotating shaft 110 can have a through hole, the elastic sheet 1412 can pass through the through hole, and can be arranged in a direction perpendicular to the axis of the rotating shaft 110. The elastic sheet 1412 is located on one side of the rotating shaft 110 and is provided with a first connecting rod 1413. The first connecting rod 1413 can be connected to the fixing frame 120. The elastic sheet 1412 is located on the other side of the rotating shaft 110 and is provided with a second connecting rod 1414. The second connecting rod 1414 can extend into the limiting hole 151.

[0118] For example, the rotating shaft 110 may be provided with a perforation, arranged perpendicularly to the rotating shaft 110 and having a predetermined height along the diameter of the rotating shaft 110. The fixing plate 150 may be freely movable within the perforation along the height of the perforation. A third fixing hole 121 may be provided on the side of the fixing frame 120 facing the fixing plate 150, and the first connecting rod 1413 may be inserted into the third fixing hole 121. The second connecting rod 1414 may be inserted into the retaining hole 151 in the fixing plate 150. The elastic plate 1412 may be deformable. When the fixing frame 120 rotates relative to the rotating shaft 110, the first connecting rod 1413 may rotate with the fixing frame 120, thereby driving the elastic plate 1412 to rotate. Within the target range, the elastic plate 1412 moves along the height of the rotating shaft 110, while the second connecting rod 1414 moves along the direction of the retaining hole 151. In this case, the elastic plate 1412 moves synchronously with the fixing frame 120 and does not deform. When the rotation angle of fixing frame 120 exceeds the target threshold, second connecting rod 1414 is blocked by the first side surface of retaining hole 151. First connecting rod 1413 continues to rotate along with fixing frame 120, driving fixing plate 150 to rotate. Because second connecting rod 1414 is restrained, elastic plate 1412 deforms, generating a restoring force. If the direction of the torque generated by the deformation of elastic plate 1412 is the same as the torque generated by shaft sleeve assembly 130, the restoring force is superimposed on the first resistance, thereby increasing the first resistance. If the direction of the torque generated by the deformation of elastic plate 1412 is opposite to the torque generated by shaft sleeve assembly 130, the restoring force is superimposed on the first resistance, thereby reducing the first resistance.

[0119] In order to facilitate the understanding of the embodiments of the present disclosure, Figure 7A and Figure 7B The opening and closing of the second target part relative to the first target part in the embodiment of the present disclosure is described.

[0120] Figure 7A Schematically shows one of the opening and closing diagrams of the connecting device according to an embodiment of the present disclosure; Figure 7B The second schematic diagram of opening and closing of the connecting device according to an embodiment of the present disclosure is schematically shown.

[0121] in, Figure 7A The diagram schematically shows the state of one end of the torsion spring 1411 in the limiting hole 151 when the opening and closing angle of the second target part relative to the first target part is 0 degrees. Figure 7B The diagram schematically shows the state of one end of the torsion spring 1411 in the limiting hole 151 when the opening and closing angle of the second target part relative to the first target part is 90 degrees.

[0122] Reference Figure 7AWhen the opening and closing angle of the second target member relative to the first target member is 0 degrees, the second end of the torsion spring 1411 can be located in the limiting hole 151, and the second end of the torsion spring 1411 can be in contact with the second side surface of the limiting hole 151. The second side surface of the limiting hole 151 is opposite to the first side surface of the limiting hole 151. The second side surface of the limiting hole 151 can be spaced apart from the first side surface of the limiting hole 151 along the circumference of the rotating shaft 110.

[0123] When the opening angle of the second target member relative to the first target member is between 0° and 90° and increases, the second end of the torsion spring 1411 can slide along the direction of the retaining hole 151. At this point, the torque provided by the torsion spring 1411 is zero, unaffecting the first resistance generated by the sleeve assembly 130, allowing the second target member to open more easily relative to the first. When the opening angle of the second target member relative to the first target member exceeds 90° and the angle continues to increase, the first side surface of the retaining hole 151 forms a barrier against the second end of the torsion spring 1411, restricting its position. This prevents the second end of the torsion spring 1411 from rotating synchronously with the mounting bracket 120, causing it to deform and generate a restoring force, which serves as the second resistance. Because the rotational torque generated by the deformation of the torsion spring 1411 is in the same direction as the torque generated by the sleeve assembly 130, the second resistance is superimposed on the first resistance, increasing the first resistance. Therefore, when this structure is applied to a laptop computer, not only does the screen not shake due to the increased first resistance when the user performs touch screen operations on the display, but it can also effectively offset the weight of the display when the display is opened at a large angle, making it less likely to fall, and also facilitating wide-angle touch operations.

[0124] When the second target member is closed at an angle from 180° to 90° relative to the first target member, the second end of torsion spring 1411 can continue to be blocked by the first side surface of retaining hole 151. In other words, the second end of torsion spring 1411 is retained. As the first end of torsion spring 1411 rotates synchronously with mounting bracket 120, the deformation of torsion spring 1411 gradually decreases, and the second end of torsion spring 1411 is no longer able to rotate synchronously with the first end of mounting bracket 120. At this point, the torque generated by the deformation of torsion spring 1411 is in the opposite direction of the torque generated by sleeve assembly 130. The force generated by the return of torsion spring 1411's deformation adds to the first resistance, reducing the first resistance. As torsion spring 1411 gradually returns to 90° with mounting bracket 120, the deformation of torsion spring 1411 decreases to zero. When the closed angle between the second target element and the first target element is between 90° and 0° and decreases, the second end of torsion spring 1411 can slide along retaining hole 151 without deforming. At this point, the direction in which torsion spring 1411 slides within retaining hole 151 is opposite to the direction in which torsion spring 1411 slides within retaining hole 151 when the angle is between 0° and 90°. Because torsion spring 1411 remains unchanged, the torque it provides is zero, unaffecting the first resistance originally generated by sleeve assembly 130.

[0125] Based on the above connection device, the present disclosure also provides an electronic device. Figure 8 The device is described in detail.

[0126] Figure 8 The schematic diagram shows the structure of an electronic device according to an embodiment of the present disclosure.

[0127] like Figure 8 As shown, the electronic device 200 of this embodiment includes: a first target part 201 , a second target part 202 , and a connecting device 100 connecting the first target part 201 and the second target part 202 .

[0128] The connecting device 100 includes: a rotating shaft 110, a first end of the rotating shaft 110 is used to be fixedly connected to the first target part 201; a fixing frame 120, which is arranged at the second end of the rotating shaft 110, and the fixing frame 120 is used to rotationally connect the second target part 202 to the rotating shaft 110; a shaft sleeve assembly 130, which is respectively connected to the fixing frame 120 and the rotating shaft 110, and the shaft sleeve assembly 130 is used to provide a first resistance during the rotation of the fixing frame 120 relative to the rotating shaft 110, so that the first target part 201 can be at different opening and closing angles relative to the second target part 202; a target assembly 140, which is respectively connected to the fixing frame 120 and the rotating shaft 110, when the opening and closing angle is within the target range, the torque provided by the target assembly 140 is zero, and when the opening and closing angle is greater than the target threshold, the target assembly 140 is used to increase or decrease the first resistance according to the opening and closing angle.

Any electronic device 200 that requires the hinge 110 for flipping is included within the scope of the present invention.
