Description

Technical Field

[0001] The present application relates to the field of electronic equipment, and in particular to a bracket and electronic equipment. Background Art

[0002] Currently, electronic devices such as mobile phones and tablets are becoming indispensable items in people's daily lives. When users use electronic devices to read or watch videos, they usually need to use a stand to support the electronic device so that a certain angle is formed between the display screen of the electronic device and the support base for easy use. However, the stands currently available on the market can usually only be flipped open in a single direction relative to the electronic device, and the tilt posture of the electronic device is limited. Users cannot flexibly adjust the tilt posture of the stand according to actual needs, resulting in a poor user experience. Summary of the Invention

[0003] Embodiments of the present application provide a bracket and an electronic device, aiming to provide a bracket that can be opened in multiple directions, and an electronic device including the bracket.

[0004] In a first aspect, a bracket is provided. The bracket includes a fixed seat, a movable seat, and a support member. The movable seat is rotatably connected to the fixed seat and can rotate relative to the fixed seat around a first axis. One end of the support member is rotatably connected to the movable seat and can rotate relative to the movable seat around a second axis. The first axis and the second axis are not parallel. One of the fixed seat and the movable seat is provided with a first protrusion, and the other is provided with a first groove. The first protrusion is located in the first groove. In the circumferential direction around the first axis, the first groove includes a first end wall and a second end wall arranged opposite to each other, and the spacing between the first end wall and the second end wall is greater than the size of the first protrusion. When the movable seat rotates relative to the fixed seat, the first protrusion slides between the first end wall and the second end wall relative to the bottom wall of the first groove.

[0005] It is understandable that a general bracket can usually only be flipped open in a single direction relative to the device housing of the electronic device to achieve the support function. This results in the user being unable to adjust the tilt posture of the bracket according to actual needs, and the tilt posture of the electronic device is limited, resulting in a poor user experience. The bracket in the embodiment of the present application includes a fixed seat, a movable seat and a support member. The support member can rotate around a second axis relative to the movable seat to open relative to the movable seat so that the support member can support the electronic device. On this basis, the movable seat can also rotate around a first axis relative to the fixed seat to change the position of the movable seat, thereby changing the direction in which the support member opens relative to the device housing to adjust the tilt posture of the support member. Among them, the first axis and the second axis are not parallel. In other words, the support member of the bracket in this embodiment can be opened in different directions according to the actual needs of the user to adjust the tilt posture of the bracket, so that the electronic device can have a variety of tilt postures to adapt to the user's usage needs in different usage scenarios, and the user experience is better.

[0006] Secondly, in this embodiment, one of the movable seat and the fixed seat is provided with a first groove, and the other is provided with a first protrusion. When the movable seat rotates relative to the fixed seat, the first protrusion can slide between the two end walls (i.e., the first end wall and the second end wall in this embodiment) provided along the circumferential direction of the first axis of the first groove until the first protrusion contacts one of the end walls, thereby achieving a rotation stop of the movable seat. In this way, by cooperating with the first protrusion and the first groove, the movable seat can be stopped when it rotates to different angles relative to the fixed seat, so that when the user operates the support member to drive the movable seat to rotate relative to the fixed seat, the feel of the movable seat in a specific position can be improved, so that the user can accurately operate the movable seat to rotate to a specific position, thereby improving the user experience.

[0007] In one possible implementation, the first groove is an arc-shaped groove, the arc center of the first groove coincides with the first axis, the first end wall and the second end wall are arranged at an angle, and the first protrusion includes a first side surface and a second side surface arranged opposite to each other, and the first side surface and the second side surface are arranged at an angle. When the movable seat rotates to a first position relative to the fixed seat, the first side surface abuts the first end wall, and the second side surface is spaced apart from the second end wall. When the movable seat rotates to a second position relative to the fixed seat, the second side surface abuts the second end wall, and the first side surface is spaced apart from the first end wall. In this way, the first groove is an arc-shaped groove, which can facilitate the rotation between the movable seat and the fixed seat. At the same time, through the cooperation of the first protrusion and the first groove, the movable seat can be stopped when rotating to different angles relative to the fixed seat. When the user operates the support member to drive the movable seat to rotate relative to the fixed seat, the feel of the movable seat in a specific position (i.e., the first position and the second position in this embodiment) can be improved, allowing the user to accurately operate the movable seat to rotate to a specific position, thereby improving the user experience.

[0008] In one possible implementation, when the movable seat is in the first position, the angle formed between the second side surface of the first protrusion and the second end wall is 90°. In this way, when the movable seat is switched from the first position to the second position, the movable seat can rotate 90° relative to the fixed seat. When the bracket is used in an electronic device, the bracket can better support the vertical screen display and horizontal screen display of the electronic device. For example, when the movable seat is in the first position, the bracket can be used to support the vertical screen display of the electronic device; when the movable seat is in the second position, the bracket can be used to support the horizontal screen display of the electronic device. In this way, through the cooperation of the first protrusion and the first groove, the user can switch the movable seat from the first position to the second position, or switch the movable seat from the second position to the first position more quickly and accurately, so as to quickly realize the switching of the electronic device between different postures and enhance the user experience.

[0009] In one possible implementation, the movable base is plate-shaped, and the fixed base includes a base plate. The base plate and the movable base are stacked and rotatably connected. The first groove is provided on the side of the movable base facing the base plate, and the first protrusion is provided on the side of the base plate facing the movable base. In this way, the first protrusion can be located within the first groove and between the base plate and the movable base, so that the base plate can cover the first protrusion and the first groove, ensuring the uniform appearance of the bracket.

[0010] In one possible implementation, a first notch is provided at one end of the support member connected to the movable seat, and the first notch includes a first groove wall and a second groove wall arranged opposite to each other. The movable seat includes a main body portion and a mounting portion connected thereto, the main body portion being rotatably connected to the fixed seat, a first groove being formed in the main body portion, and the mounting portion being provided with a first through hole, at least a portion of the mounting portion being located within the first notch. The bracket also includes a rotating shaft core and a first elastic member, the rotating shaft core being provided through the first through hole, and having two ends respectively passing through the first groove wall and the second groove wall and connected to the support member, the first elastic member being mounted on the movable seat, at least a portion of the first elastic member being located within the first through hole and abutting between the first groove wall and the second groove wall, and the first elastic member being used to provide torque when the support member rotates relative to the movable seat.

[0011] It will be appreciated that in this embodiment, by positioning a portion of the first elastic member within the first through-hole and abutting between the first and second slot walls, both the first and second slot walls can be subjected to positive pressure from the first elastic member. Thus, when the support member rotates relative to the movable seat, significant friction is generated between the first and second slot walls of the support member and the first elastic member, thereby hindering the rotation of the support member relative to the movable seat. In other words, the first and second slot walls of the support member can cooperate with the first elastic member to provide torque for the rotation of the support member relative to the movable seat, thereby enhancing the user experience.

[0012] In one possible implementation, the first elastic member includes a first cantilever and a second cantilever that are spaced apart and arranged opposite to each other, the first cantilever abuts the first groove wall, and the second cantilever abuts the second groove wall. When the support member rotates relative to the movable seat, the first cantilever and the second cantilever are deformed, and the distance between the first cantilever and the second cantilever changes.

[0013] It can be understood that in this embodiment, by setting the first cantilever of the first elastic member to abut against the first groove wall, and setting the second cantilever of the first elastic member to abut against the second groove wall, the first groove wall and the second groove wall of the support member can both be subjected to positive pressure from the first elastic member, thereby increasing the friction between the support member and the first elastic member when the support member rotates relative to the movable seat. At the same time, when the support member rotates relative to the movable seat, the first cantilever and the second cantilever can both be deformed to change the distance between the first cantilever and the second cantilever, thereby providing torque for the rotation of the support member relative to the movable seat. In other words, in this embodiment, the friction between the first elastic member and the support member, as well as the elastic force generated by the deformation of the first elastic member itself, can be combined to jointly provide torque for the rotation of the support member relative to the movable seat, thereby improving the user experience.

[0014] In one possible implementation, the first elastic member also includes a first connecting arm and a second connecting arm, one end of the first connecting arm is fixedly connected to the first cantilever, and the other end is fixed to the movable seat, and one end of the second connecting arm is fixedly connected to the second cantilever, and the other end is fixed to the movable seat.

[0015] It is understood that in this embodiment, by providing the first and second connecting arms, the lengths of the first and second cantilevers are respectively extended, so that the first elastic member can provide a torque for the support member to rotate relative to the movable seat through the elastic force generated by the combined deformation of the first cantilever and the first connecting arm, and the combined deformation of the second cantilever and the second connecting arm. On the one hand, the torque provided by the first elastic member when the support member rotates relative to the movable seat is increased, thereby improving the support stability of the bracket. On the other hand, by providing the first and second connecting arms, the lengths of the first and second cantilevers are extended, which helps to avoid stress concentration on the first and second cantilevers, thereby improving the fatigue resistance of the first elastic member and extending the service life of the first elastic member.

[0016] In one possible implementation, the first elastic member further includes a first connecting arm, a second connecting arm, and a bottom arm, wherein one end of the first connecting arm is fixedly connected to the first cantilever, and the other end is fixedly connected to one end of the bottom arm; one end of the second connecting arm is fixedly connected to the second cantilever, and the other end is fixedly connected to the other end of the bottom arm; a gap is formed between the first connecting arm, the second connecting arm, and the bottom arm. In this way, the first elastic member can provide a torsional force for the support member to rotate relative to the movable seat through the elastic force generated by the combined deformation of the first cantilever, the second cantilever, the first connecting arm, the second connecting arm, and the bottom arm, thereby facilitating improved support stability of the bracket.

[0017] In one possible implementation, the main body further includes a second groove, which is spaced apart from the first groove and communicates with the first through-hole. The first connecting arm, the second connecting arm, and the bottom arm are all received in the second groove, and the first connecting arm and the second connecting arm each abut the sidewalls of the second groove. Thus, by arranging the first connecting arm and the second connecting arm to abut the sidewalls of the second groove, a portion of the first elastic member can be embedded in the second groove of the movable seat, thereby achieving installation and fixation of the first elastic member to the movable seat. In other words, the first elastic member in this embodiment does not require additional fixings; its shape alone can achieve fixation with the movable seat, which helps to simplify the number of parts in the bracket and save manufacturing costs.

[0018] In one possible implementation, the first connecting arm is arc-shaped, with the center of the first connecting arm coinciding with the first axis. And / or, the second connecting arm is arc-shaped, with the center of the second connecting arm coinciding with the first axis. Thus, by providing the first connecting arm with an arc shape, the first connecting arm itself has no corners, and the first connecting arm itself is less susceptible to stress concentration, thereby improving the fatigue resistance of the first connecting arm. Furthermore, by providing the second connecting arm with an arc shape, the second connecting arm itself has no corners, and the second connecting arm itself is less susceptible to stress concentration, thereby improving the fatigue resistance of the second connecting arm.

[0019] In one possible implementation, the bracket further includes an elastic compression member disposed between the first and second cantilever arms. This arrangement increases the positive pressure exerted by the first cantilever arm on the first sidewall and the second cantilever arm on the second sidewall, thereby increasing the frictional force that must be overcome when the support member rotates relative to the movable seat. In other words, by disposing the elastic compression member between the first and second cantilever arms, this embodiment facilitates increased torque during rotation of the support member relative to the movable seat, enhancing the user experience.

[0020] In one possible implementation, the bracket further includes a sleeve, which is inserted into the first through hole and sleeved onto the rotating shaft core. Two ends of the sleeve respectively abut the first slot wall and the second slot wall. The sleeve defines a mounting slot, which includes a first side wall and a second side wall disposed opposite each other. A portion of the first elastic member is located within the mounting slot and abuts between the first side wall and the second side wall.

[0021] It is understood that in this embodiment, by providing the first cantilever of the first elastic member to abut the first side wall of the sleeve, and providing the second cantilever of the first elastic member to abut the second side wall of the sleeve, the first groove wall and the second groove wall of the support member can indirectly withstand the positive pressure from the first elastic member through the sleeve. In this way, by providing the sleeve, the first elastic member can easily provide positive pressure to the first groove wall and the second groove wall of the support member, and assembly is more convenient.

[0022] In one possible implementation, a portion of the first cantilever is located within the mounting groove and abuts the first sidewall, while a portion of the second cantilever is located within the mounting groove and abuts the second sidewall. In this way, the first and second sidewalls of the sleeve can be subjected to squeezing forces from the first and second cantilever arms, respectively, thereby increasing the friction between the sleeve and the first elastic member, thereby facilitating increased torque when the support member rotates relative to the movable seat.

[0023] In one possible implementation, the sleeve is fixedly connected to the rotating shaft core, the rotating shaft core is fixedly connected to the support member, the first side wall is provided with a first protrusion, and the first elastic member is provided with a first matching protrusion facing the first side wall. When the support member rotates relative to the movable seat, the sleeve rotates relative to the first elastic member, and the first protrusion squeezes the first matching protrusion to provide torque for the support member to rotate relative to the movable seat.

[0024] It is understood that in this embodiment, by providing the first protrusion to cooperate with the first mating protrusion, when the support member rotates relative to the movable seat and drives the sleeve to rotate relative to the movable seat, the first protrusion and the first mating protrusion can be squeezed against each other, thereby generating a large elastic force to hinder the rotation of the support member relative to the movable seat. In other words, in this embodiment, the cooperation between the first protrusion and the first mating protrusion provides torque for the rotation of the support member relative to the movable seat, thereby improving the user experience.

[0025] In one possible implementation, the first elastic member is provided with a first groove and a second groove, and the first groove and the second groove are located on opposite sides of the first mating protrusion. When the bracket is in a closed state, the first protrusion is located in the first groove, and when the bracket is in an open state, the first protrusion is located in the second groove. When the bracket switches from a closed state to an open state, the sleeve rotates relative to the first elastic member, the first protrusion passes over the first mating protrusion, and slides into the second groove.

[0026] It can be understood that the sleeve in this embodiment cooperates with the first mating protrusion of the first elastic member by providing a first protrusion, so that when the support member is opened relative to the movable seat until the first protrusion passes over the first mating protrusion, the first protrusion can automatically slide into the second groove, so that the bracket can automatically switch from the intermediate state to the open state. Also, when the support member is closed relative to the movable seat until the first protrusion passes over the first mating protrusion, the first protrusion can automatically slide into the first groove, so that the bracket can automatically switch from the intermediate state to the closed state. In other words, in this embodiment, by providing the first protrusion and the first mating protrusion to cooperate, the bracket can realize the self-opening and self-closing functions of the support member relative to the movable seat, and the user experience is better.

[0027] In one possible implementation, the mounting slot further includes a third sidewall connected between the first and second sidewalls, and the sleeve is capable of opening relative to the movable seat until the third sidewall contacts the first elastic member. Thus, when the bracket is in the open position, the third sidewall of the sleeve can contact a portion of the lower surface of the first elastic member, thereby achieving a fixed position.

[0028] In one possible implementation, a rotating column is provided on the side of the movable seat facing the fixed seat, the central axis of the rotating column coinciding with the first axis, and the fixed seat is sleeved around the rotating column. The bracket further includes a second elastic member and a fastener. The second elastic member is located on the side of the fixed seat facing away from the movable seat and sleeved around the rotating column. A portion of the fastener is fixedly connected to the rotating column, while a portion of the fastener compresses the second elastic member along the axial direction of the rotating column. Under the action of the fastener, the second elastic member compresses the fixed seat, and the second elastic member is configured to provide torsional force when the movable seat rotates relative to the fixed seat.

[0029] It is understandable that in this embodiment, by providing a second elastic member on the side of the fixed seat facing away from the movable seat, and by providing a fastener to lock with the movable seat in a direction parallel to the first axis, the fastener can squeeze the second elastic member in a direction parallel to the first axis. Under the action of the fastener, the second elastic member can squeeze the movable seat, so that the movable seat can abut the fixed seat. In other words, the movable seat can be subjected to positive pressure from the second elastic member. In this way, when the movable seat rotates relative to the fixed seat, a large friction force can be generated between the movable seat and the fixed seat, thereby hindering the rotation of the movable seat relative to the fixed seat. In other words, the second elastic member can cooperate with the fastener to provide torque for the rotation of the movable seat relative to the fixed seat, thereby improving the user experience.

[0030] In one possible implementation, the bracket further includes a cam ring, which is sleeved around the rotating column and fixedly connected to the rotating column. The cam ring is positioned between the fixed seat and the second elastic member, and abuts the fixed seat under the action of the second elastic member. One of the cam ring and the fixed seat is provided with a second protrusion, and the other is provided with a third groove. The cam ring can rotate relative to the fixed seat under the action of the movable seat, so that the second protrusion slides into or out of the third groove. In this way, the cooperation between the second protrusion and the third groove allows the movable seat to self-lock at a specific position during its rotation relative to the fixed seat, thereby improving the user experience.

[0031] In one possible implementation, the mount is a magnetic element. Alternatively, a magnetic element is provided within the mount. This allows for a detachable connection between the mount and other devices, providing a better user experience.

[0032] In one possible implementation, the projections of the movable base and the support member on the plane of the fixed base jointly cover at least a portion of the fixed base. This allows the fixed base to have a larger planar surface, allowing for the installation of more magnetic elements within the fixed base, or for the fixed base itself to function as a larger magnetic element. This improves the connection reliability between the bracket and other devices, and enhances the support stability of the bracket.

[0033] In one possible implementation, the bottom plate of the fixed seat is provided with an avoidance space, and the avoidance space is used to avoid the movable seat and the support member. In this way, the plane size of the bottom plate is larger, and it can accommodate multiple magnetic elements or accommodate larger magnetic elements, thereby improving the fixing stability between the bracket and other components (such as the shell body). At the same time, the movable seat and the support member can also be located in the avoidance space a of the bottom plate. On the one hand, the thickness of the fixed seat can be utilized to reduce the overall thickness of the bracket; on the other hand, part of the bottom plate can be flush with the movable seat and the support member, thereby ensuring the aesthetic appearance of the bracket and improving the user experience.

[0034] In a second aspect, a housing device is provided, which includes a housing body and the bracket, wherein a fixing seat of the bracket is fixedly connected to the housing body.

[0035] It can be understood that the bracket of the shell device in this embodiment includes a fixed seat, a movable seat and a support member, and the support member can rotate around the second axis relative to the movable seat to open relative to the movable seat, so that the support member can support the electronic device. On this basis, the movable seat can also rotate around the first axis relative to the fixed seat to change the position of the movable seat, thereby changing the direction in which the support member opens relative to the shell body to adjust the tilt posture of the support member. Among them, the first axis is not parallel to the second axis. In other words, the support member of the bracket in this embodiment can be opened in different directions according to the actual needs of the user to adjust the tilt posture of the bracket, so that the shell device can have a variety of tilt postures to adapt to the user's usage needs in different usage scenarios, and the user experience is better.

[0036] In one possible implementation, the bracket's mounting base is detachably connected to the housing. Alternatively, the housing may be provided with a magnetic element, and the mounting base is a magnetic attraction element, which cooperates with the magnetic element to secure the bracket to the housing. This detachable connection between the bracket and the housing allows for adaptability to different user scenarios, resulting in a better user experience.

[0037] In a third aspect, an electronic device is provided. The electronic device includes a screen, a device housing, and the above-mentioned housing device, the screen is mounted on the device housing, and the housing device is located on the side of the device housing facing away from the screen, and is sleeved on the device housing. In this way, the housing device can be sleeved on the device housing of the electronic device as a protective cover. In other words, the support member of the bracket in this embodiment can be opened in different directions according to the actual needs of the user to adjust the tilt posture of the bracket, so that the electronic device can have a variety of tilt postures to adapt to the user's usage needs in different usage scenarios, and the user experience is better.

[0038] In a fourth aspect, an electronic device is provided. The electronic device includes a screen, a device housing and the above-mentioned bracket, the screen is mounted on the device housing, and the fixed seat of the bracket is fixedly connected to the device housing. It can be understood that the bracket of the electronic device in this embodiment includes a fixed seat, a movable seat and a support member, and the support member can rotate around the second axis relative to the movable seat to open relative to the movable seat, so that the support member can support the electronic device. On this basis, the movable seat can also rotate around the first axis relative to the fixed seat to change the position of the movable seat, thereby changing the direction in which the support member opens relative to the housing body to adjust the tilt posture of the support member. The first axis is not parallel to the second axis. In other words, the support member of the bracket in this embodiment can be opened in different directions according to the actual needs of the user to adjust the tilt posture of the bracket, so that the electronic device can have a variety of tilt postures to adapt to the user's usage needs in different usage scenarios, and the user experience is better.

[0039] In one possible implementation, the bracket's mounting base is detachably connected to the device housing. Alternatively, a magnetic element is provided within the device housing, and the mounting base is a magnetic attraction element, which cooperates with the magnetic element to secure the bracket to the device housing. This detachable connection between the bracket and the device housing allows for adaptability to different user scenarios, resulting in a better user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0083] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first," "second," "third," or "fourth" may explicitly or implicitly include one or more of the features.

[0084] In the embodiments of this application, "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0085] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in some other embodiments," and "in another embodiment" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof all mean "including but not limited to," unless otherwise specifically emphasized.

[0086] It is understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings.

[0087] Figure 1 1 is a structural diagram of an electronic device 1000 provided by an embodiment of the present application when the bracket 100 is in a closed state and the movable seat 20 of the bracket 100 is in a first position. Figure 2 yes Figure 1 The electronic device 1000 is shown as a schematic structural diagram when the bracket 100 is in the open state. Figure 3 yes Figure 1 The electronic device 1000 shown is a schematic structural diagram when the bracket 100 is in a closed state and the movable seat 20 of the bracket 100 is in the second position. Figure 4 yes Figure 3 The electronic device 1000 is shown as a schematic structural diagram when the bracket 100 is in the open state.

[0088] like Figures 1 to 4 As shown, the electronic device 1000 may include a device housing 200 and a screen 300. The screen 300 may be installed in the device housing 200. The electronic device 1000 may also include a bracket 100. The bracket 100 may be located on the side of the device housing 200 facing away from the screen 300 and fixedly connected to the device housing 200. The bracket 100 may have an open state and a closed state. When the bracket 100 is in the closed state, the electronic device 1000 may be placed flat on a support table (not shown) for user use. Alternatively, the user may also hold the electronic device 1000 for use. When the bracket 100 is in the open state, a portion of the bracket 100 may be set at an angle to the screen 300 and supported on the support table. At this time, the screen 300 of the electronic device 1000 may be set at an angle to the support table for user use. It should be noted that the support table may be a physical structure such as a table or a booth, or it may be a part of the human body such as a hand or a leg, or it may be other virtual structures. It is understandable that the support platform can be a flat surface, a curved surface or other shapes, and this application does not limit this.

[0089] In some embodiments, the electronic device 1000 may include, but is not limited to, a two-in-one product, an all-in-one computer, and a mobile phone. A two-in-one product typically includes a main unit and a keyboard assembly, wherein the main unit and the keyboard assembly are detachably connected. After the main unit is separated from the keyboard assembly, the main unit can still be used as an independent electronic device 1000. For example, the main unit may be a tablet computer.

[0090] In some embodiments, the electronic device 1000 may also be a foldable electronic device 1000, such as a foldable mobile phone or tablet computer. For example, the electronic device 1000 may have a two-fold structure. The device housing 200 may include a first housing (not shown), a second housing (not shown), and a hinge (not shown). The hinge may connect the first and second housings. The hinge may move to allow the first and second housings to open relative to each other to a flattened state, or to fold relative to each other to a closed state. The bracket 100 may be fixedly connected to one of the first and second housings. In other embodiments, the electronic device 1000 may have a structure that folds three or more times, meaning that the device housing 200 of the electronic device 1000 may include three or more flat panels. Adjacent flat panels are connected by a bend, and the two panels can rotate relative to each other to overlap or rotate away from each other to flatten. When the electronic device 1000 has a structure that folds three or more times, the structure of the electronic device 1000 can be adaptively designed by referring to the description of the two-fold structure above and will not be repeated here.

[0091] Figure 5 yes Figure 1 The electronic device 1000 shown is a schematic cross-sectional structure diagram of an embodiment taken along line AA.

[0092] like Figure 5 As shown, the bracket 100 may include a fixed base 10, a movable base 20, and a support member 30. The movable base 20 can be rotatably connected to the fixed base 10 and can rotate relative to the fixed base 10 about a first axis T1. The support member 30 may include a connecting end 30a and a supporting end 30b. The connecting end 30a of the support member 30 can be rotatably connected to the movable base 20 and can rotate relative to the movable base 20 about a second axis T2. The connecting end 30a of the support member 30 can rotate relative to the movable base 20, so that the supporting end 30b of the support member 30 can open or close relative to the movable base 20, thereby enabling the bracket 100 to switch between an open state and a closed state. The first axis T1 may not be parallel to the second axis T2. For example, the first axis T1 may be perpendicular to the second axis T2. Thus, when the bracket 100 is in the open state, the tilt of the bracket 100 can be changed by controlling the support member 30 to drive the movable base 20 to rotate relative to the fixed base 10, thereby changing the position of the movable base 20.

[0093] Illustratively, the fixing base 10 can be fixedly connected to the surface of the device housing 200 facing away from the screen 300. For example, the fixing base 10 can be fixedly connected to the device housing 200 by bonding, snapping, screwing, or other methods. The fixing base 10 can be detachably connected to the device housing 200 or non-detachably connected. In this embodiment, the fixing base 10 can be a magnetic member such as a magnet. The fixing base 10 can be attracted to the metal and / or magnetic portion of the device housing 200 to secure the bracket 100 to the device housing 200. In this way, the fixing base 10 can be detachably connected to the device housing 200. In some embodiments, the device housing 200 may also be provided with a magnetic member. The magnetic member can cooperate with the fixing base 10 to secure the bracket 100 to the device housing 200. In this way, the magnetic member in the device housing 200 cooperates with the fixing base 10, thereby improving the stability of the connection between the bracket 100 and the device housing 200. In other embodiments, the device housing 200 of the electronic device 1000 may also be provided with a mating seat. The mating seat can be used to cooperate with the fixing seat 10 to fix the fixing seat 10 and the electronic device 1000.

[0094] In some embodiments, the bracket 100 can also be applied to a shell device (not shown). The shell device may include a shell body. The bracket 100 can be fixedly connected to the shell body. The shell device can serve as a protective shell independent of the electronic device 1000. The shell body of the shell device can be located on the side of the device shell 200 of the electronic device 1000 facing away from the screen 300, and can be mounted on the device shell 200 of the electronic device 1000. The shell device can be removed from the device shell 200. In this way, on the one hand, the shell device can be used to protect the device shell 200 of the electronic device 1000, and on the other hand, when the shell device is damaged, the shell device can be detachably connected to the device shell 200, so that the shell device is easy to replace and repair, and the maintenance cost is low. In other embodiments, the bracket 100 can also be applied to other structural parts or products that need support.

[0095] It is understandable that a typical bracket can usually only be flipped open in a single direction relative to the device housing of the electronic device to achieve the support function. This results in the user being unable to adjust the tilt posture of the bracket according to actual needs, and the tilt posture of the electronic device is limited, resulting in a poor user experience. The bracket 100 in the embodiment of the present application includes a fixed base 10, a movable base 20, and a support member 30. The support member 30 can be opened relative to the movable base 20 so that the support member 30 can support the electronic device 1000. On this basis, the movable base 20 can also rotate relative to the fixed base 10 to change the position of the movable base 20, thereby changing the direction in which the support member 30 opens relative to the device housing 200 to adjust the tilt posture of the support member 30. In other words, the support member 30 of the bracket 100 in this embodiment can be opened in different directions according to the actual needs of the user to adjust the tilt posture of the bracket 100, so that the electronic device 1000 can have a variety of tilt postures to adapt to the user's usage needs in different usage scenarios, and the user experience is better.

[0096] The specific structure of the bracket 100 provided in this application will be introduced below with reference to relevant drawings.

[0097] Figure 6 yes Figure 1 The structure diagram shown is when the bracket 100 is in a closed state and the movable seat 20 is in a first position. Figure 7 yes Figure 6 The illustrated schematic diagram is an exploded structural diagram of the stent 100 in some embodiments. Figure 8 yes Figure 7 The structure diagram of the movable seat 20 of the bracket 100 shown is shown in another perspective.

[0098] like Figures 6 to 8 As shown, the movable seat 20 may include a main body portion 21 and a mounting portion 22. The main body portion 21 may be roughly disc-shaped. The mounting portion 22 may be fixedly connected to the peripheral side surface of the main body portion 21. The mounting portion 22 may be provided with a first through hole 221. The main body portion 21 may include a top surface 21a and a bottom surface 21b disposed opposite to each other. The main body portion 21 may be provided with a first groove 211 and a second groove 212 disposed at intervals. The openings of the first groove 211 and the second groove 212 may both be formed on the bottom surface 21b of the main body portion 21. It should be noted that, for ease of understanding, Figure 7 The main body 21 and the mounting portion 22 of the movable seat 20 are schematically divided by dotted lines. Although the movable seat 20 is divided into two parts (i.e., the main body 21 and the mounting portion 22) in this embodiment, it does not affect the movable seat 20 being an integrally formed structure, i.e., the main body 21 and the mounting portion 22 can be integrally formed.

[0099] Figure 9 yes Figure 7The support member 30 and the rotating shaft core 40 are shown as exploded structural schematic diagrams in some embodiments. Figure 10 yes Figure 6 The shown diagram is a partial cross-sectional structural diagram of an embodiment of the bracket 100 cut along line BB.

[0100] like Figure 9 and Figure 10 As shown, the support member 30 may include a connecting end 30a and a supporting end 30b (please refer to Figure 7 As shown). The connecting end 30a of the support member 30 may be provided with a first notch 31. The first notch 31 may include a first groove wall 311 and a second groove wall 312 arranged opposite to each other. Among them, the connecting end 30a of the support member 30 may also be provided with a first hole 32 and a second hole 33. The first hole 32 may pass through the first groove wall 311 and be connected to the first notch 31. The second hole 33 may pass through the second groove wall 312 and be connected to the first notch 31. The first hole 32 and the second hole 33 may be arranged opposite to each other. Exemplarily, the support member 30 may also be provided with an avoidance hole 34. The avoidance hole 34 may be located on the side of the first notch 31 facing the support end 30b. The avoidance hole 34 may be connected to the first notch 31. It should be understood that Figure 7 The structure of the support member 30 is also illustrated from another perspective.

[0101] Exemplarily, the bracket 100 may further include a rotating shaft core 40. The rotating shaft core 40 may include a first end portion 41, a middle portion 42, and a second end portion 43 connected in sequence. The middle portion 42 may be located in the first notch 31, and both ends are passed through the first hole 32 and the second hole 33. The radial dimension of the first end portion 41 may be greater than the dimension of the first hole 32. The radial dimension of the second end portion 43 may be greater than the dimension of the second hole 33. In this way, the first end portion 41 and the second end portion 43 of the rotating shaft core 40 may clamp the rotating shaft core 40 in the first hole 32 and the second hole 33 to prevent the rotating shaft core 40 from sliding in the first hole 32 and the second hole 33 along the axial direction of the first hole 32. Exemplarily, the second end portion 43 of the rotating shaft core 40 may be detachably connected to the middle portion 42 to facilitate assembly between the rotating shaft core and the support member 30. It should be understood that Figure 7 The structure of the rotating shaft core 40 is also illustrated from another perspective.

[0102] For example, the circumferential side surface of the middle portion 42 may be provided with a first planar portion 421. The inner side surface of the first hole 32 may be provided with a first mating planar portion 321. The first planar portion 421 of the rotating shaft core 40 may be arranged facing the first mating planar portion 321 of the first hole 32 and in contact with the first mating planar portion 321. In this way, the mating of the first planar portion 421 and the first mating planar portion 321 prevents relative rotation between the rotating shaft core 40 and the connecting end 30a of the support member 30, and the rotating shaft core 40 can be fixedly connected to the support member 30.

[0103] Figure 11 yes Figure 6 The shown diagram is a partial cross-sectional structural diagram of an embodiment of the bracket 100 cut along line BB.

[0104] like Figure 10 and Figure 11 As shown, the main body 21 of the movable seat 20 can be received in the avoidance hole 34. The mounting portion 22 of the movable seat 20 can be received in the first notch 31. In this case, the first through-hole 221 of the mounting portion 22 of the movable seat 20 can be located between the first groove wall 311 and the second groove wall 312. The first through-hole 221 can directly face the first hole 32 and the second hole 33 of the support member 30, and connect the first hole 32 and the second hole 33. The first through-hole 221 can be sleeved over the middle portion 42 of the rotating shaft core 40. In other words, the middle portion 42 of the rotating shaft core 40 can pass through the first through-hole 221 of the movable seat 20. In this case, the connecting end 30a of the support member 30 can drive the rotating shaft core 40 to rotate relative to the first through-hole 221 about the second axis T2. In other words, the center of rotation between the connecting end 30a of the support member 30 and the mounting portion 22 of the movable seat 20 can be the second axis T2. The second axis T2 can be the central axis of the first through-hole 221. The central axis of the first through hole 221 may coincide with the central axis of the rotating shaft core 40 .

[0105] It is understood that when the bracket 100 in this embodiment is in the closed state, a portion of the movable seat 20 can be accommodated in the avoidance hole 34 of the support member 30, so that the movable seat 20 can still utilize the size space of the support member 30, making the structure of the movable seat 20 and the support member 30 more compact. In other embodiments, the support member 30 may not be provided with the avoidance hole 34.

[0106] Figure 12 yes Figure 7 The structure diagram of the sleeve 51 of the bracket 100 shown is shown in another perspective. Figure 13 yes Figure 7 The structure diagram of the first elastic member 52 shown in FIG. 5 is shown in FIG.

[0107] like Figure 12 and Figure 13As shown, the bracket 100 may further include a first torsion structure 50 (please refer to Figure 7 The first torsion structure 50 can be used to provide a torsion force when the connecting end 30a of the support member 30 rotates relative to the movable seat 20, thereby improving the user experience. For example, the first torsion structure 50 can include a sleeve 51 and a first elastic member 52.

[0108] For example, the sleeve 51 may be provided with a second through hole 511. The inner side surface of the second through hole 511 may be provided with a second mating flat surface portion 5111. The sleeve 51 may also be provided with a mounting groove 512. The opening of the mounting groove 512 may be formed on the outer peripheral side surface of the sleeve 51 and communicate with the second through hole 511. The mounting groove 512 may include a first side wall 513 and a second side wall 514 arranged opposite to each other along the axial direction of the sleeve 51, and a third side wall 515 connected between the first side wall 513 and the second side wall 514. The first side wall 513 of the sleeve 51 may be provided with a first protrusion 516. The second side wall 514 of the sleeve 51 may be provided with a second protrusion 517. The first protrusion 516 and the second protrusion 517 may be arranged opposite to each other.

[0109] By way of example, the first elastic member 52 may include a first cantilever 521, a second cantilever 522, a first connecting arm 523, a second connecting arm 524, and a bottom arm 525. The first cantilever 521 may be opposite and spaced apart from the second cantilever 522. One end of the first cantilever 521 may be fixedly connected to the first connecting arm 523. One end of the second cantilever 522 may be fixedly connected to the second connecting arm 524. The first connecting arm 523 and the second connecting arm 524 may be located on the same side of the first cantilever 521. The end of the first connecting arm 523 facing away from the first cantilever 521 may be fixedly connected to one end of the bottom arm 525. The end of the second connecting arm 524 facing away from the second cantilever 522 may be fixedly connected to the other end of the bottom arm 525. In other words, the bottom arm 525 may be fixedly connected between the first connecting arm 523 and the second connecting arm 524. A gap 52a may be formed between the bottom arm 525 and both the first connecting arm 523 and the second connecting arm 524. It should be understood that although the first elastic member 52 is divided into multiple parts (i.e., the first cantilever 521, the second cantilever 522, the first connecting arm 523, the second connecting arm 524 and the bottom arm 525) for description in this embodiment, it does not affect the first elastic member 52 being an integrally formed structure, i.e., the first cantilever 521, the second cantilever 522, the first connecting arm 523, the second connecting arm 524 and the bottom arm 525 can be integrally formed.

[0110] Exemplarily, the first connecting arm 523 can be roughly arc-shaped, such as a circular arc. That is, the first connecting arm 523 itself has no corners. In this way, the first connecting arm 523 itself is not prone to stress concentration, and the first connecting arm 523 has better fatigue resistance. Among them, the first connecting arm 523 can be bent in a direction away from the first cantilever 521. The first cantilever 521 can be fixedly connected to the arc surface of the first connecting arm 523. The first cantilever 521 can be parallel to the radial direction of the first connecting arm 523. In some embodiments, the first connecting arm 523 can also be roughly linear or other shapes such as a broken line.

[0111] For example, the second connecting arm 524 can be roughly arc-shaped, such as a circular arc. That is, the second connecting arm 524 itself has no corners. In this way, the second connecting arm 524 itself is less likely to experience stress concentration, and the second connecting arm 524 has better fatigue resistance. Among them, the second connecting arm 524 can be bent in a direction away from the second cantilever 522. The second cantilever 522 can be fixedly connected to the arc surface of the second connecting arm 524. The second cantilever 522 can be parallel to the radial direction of the second connecting arm 524. In some embodiments, the second connecting arm 524 can also be roughly linear or other shapes such as a broken line.

[0112] For example, a first mating protrusion 5211 may be provided on the side of the first cantilever 521 facing away from the second cantilever 522. A first groove 5212 and a second groove 5213 may also be provided on the side of the first cantilever 521 facing away from the second cantilever 522. The first groove 5212 and the second groove 5213 may be located on opposite sides of the first mating protrusion 5211. A second mating protrusion 5221 may be provided on the side of the second cantilever 522 facing away from the first cantilever 521. A third groove 5222 and a fourth groove 5223 may also be provided on the side of the second cantilever 522 facing away from the first cantilever 521. The third groove 5222 and the fourth groove 5223 may be located on opposite sides of the second mating protrusion 5221. The first groove 5212 and the third groove 5222 may be located on the same side of the first mating protrusion 5211 and the second mating protrusion 5221.

[0113] For example, the first elastic member 52 may be substantially axially symmetrical. The first cantilever 521 may be axially symmetrical with the second cantilever 522. The first connecting arm 523 may be axially symmetrical with the second connecting arm 524. Thus, the force applied to the first elastic member 52 is relatively symmetrical.

[0114] Figure 14 yes Figure 6 The shown diagram is a partial cross-sectional structural diagram of an embodiment of the bracket 100 cut along CC. Figure 15 yes Figure 6 The shown diagram is a partial cross-sectional structural diagram of a stent 100 in one embodiment cut along DD. Figure 16 yes Figure 6 The shown diagram is a partial cross-sectional structural diagram of an embodiment of the bracket 100 cut along line BB.

[0115] like Figures 14 to 16 As shown, the sleeve 51 can be installed in the first through hole 221 of the movable seat 20. The second through hole 511 of the sleeve 51 can be sleeved on the middle part 42 of the rotating shaft core 40. The two ends of the sleeve 51 can respectively abut the first groove wall 311 and the second groove wall 312 of the first notch 31 of the support member 30. Among them, the second matching plane portion 5111 of the sleeve 51 can be arranged facing the first plane portion 421 of the rotating shaft core 40. In this way, through the cooperation between the second matching plane portion 5111 and the first plane portion 421, the rotating shaft core 40 and the sleeve 51 will not rotate relative to each other. In other words, when the connecting end 30a of the support member 30 rotates relative to the movable seat 20, the connecting end 30a of the support member 30 can drive the rotating shaft core 40 and the sleeve 51 to rotate relative to the movable seat 20.

[0116] Exemplarily, the first connecting arm 523, the second connecting arm 524 and the bottom arm 525 of the first elastic member 52 can all be accommodated in the second groove 212 of the movable seat 20. Among them, the first connecting arm 523 can abut the groove side wall of the second groove 212. The second connecting arm 524 can abut the groove side wall of the second groove 212. In this way, by abutting the groove wall of the second groove 212 by the first connecting arm 523 and the second connecting arm 524, a part of the first elastic member 52 can be embedded in the second groove 212 of the movable seat 20, thereby realizing the installation and fixation of the first elastic member 52 and the movable seat 20. Exemplarily, the arc center of the first connecting arm 523 can be aligned with the first axis T1 (please refer to Figure 5 The arc center of the second connecting arm 524 may coincide with the first axis T1 (please refer to Figure 5 shown) overlap.

[0117] For example, the movable seat 20 may further include a connecting hole 20a. The connecting hole 20a may connect the second groove 212 with the first through hole 221. The first cantilever 521 and the second cantilever 522 may both pass through the connecting hole 20a of the movable seat 20, with portions of the first cantilever 521 and the second cantilever 522 extending into the mounting groove 512 of the sleeve 51. The first cantilever 521 may abut the first sidewall 513 of the mounting groove 512. The second cantilever 522 may abut the second sidewall 514 of the mounting groove 512.

[0118] It will be appreciated that in this embodiment, by providing the first cantilever 521 of the first elastic member 52 to abut the first side wall 513 of the sleeve 51, and by providing the second cantilever 522 of the first elastic member 52 to abut the second side wall 514 of the sleeve 51, both the first side wall 513 and the second side wall 514 of the sleeve 51 can be subjected to positive pressure from the first elastic member 52. Thus, when the connecting end 30a of the support member 30 rotates relative to the movable seat 20, driving the sleeve 51 to rotate relative to the movable seat 20, a large friction force can be generated between the first side wall 513 of the sleeve 51 and the first cantilever 521, and a large friction force can be generated between the second side wall 514 of the sleeve 51 and the second cantilever 522, thereby hindering the rotation of the support member 30 relative to the movable seat 20. In other words, the sleeve 51 can cooperate with the first elastic member 52 to provide torque for the rotation of the support member 30 relative to the movable seat 20, thereby improving the user experience.

[0119] Secondly, the first elastic member 52 in this embodiment may further include a first connecting arm 523 and a second connecting arm 524. One end of the first connecting arm 523 may be fixedly connected to the first cantilever 521, and the other end may be fixedly connected to the movable seat 20. One end of the second connecting arm 524 may be fixedly connected to the second cantilever 522, and the other end may be fixedly connected to the movable seat 20. In this way, by providing the first connecting arm 523 and the second connecting arm 524, the lengths of the first cantilever 521 and the second cantilever 522 are respectively extended, so that the first elastic member 52 can provide a torsional force for the support member 30 to rotate relative to the movable seat 20 through the elastic force generated by the combined deformation of the first cantilever 521 and the first connecting arm 523, and the combined deformation of the second cantilever 522 and the second connecting arm 524. On the one hand, the torque provided by the first elastic member 52 when the support member 30 rotates relative to the movable seat 20 is improved, thereby improving the supporting stability of the bracket 100; on the other hand, by providing the first connecting arm 523 and the second connecting arm 524, the length of the first cantilever 521 and the second cantilever 522 is extended, which is beneficial to avoiding stress concentration on the first cantilever 521 and the second cantilever 522, and is beneficial to improving the fatigue resistance of the first elastic member 52 and extending the service life of the first elastic member 52.

[0120] In addition, the first elastic member 52 in this embodiment may further include a bottom arm 525. One end of the bottom arm 525 may be fixedly connected to the end of the first connecting arm 523 facing away from the first cantilever 521, and the other end of the bottom arm 525 may be fixedly connected to the end of the second connecting arm 524 facing away from the second cantilever 522. A gap 52a may be formed between the bottom arm 525 and the first connecting arm 523 and the second connecting arm 524. In this way, the first elastic member 52 can provide a torsional force for the support member 30 to rotate relative to the movable seat 20 through the elastic force generated by the combined deformation of the first cantilever 521, the second cantilever 522, the first connecting arm 523, the second connecting arm 524, and the bottom arm 525, thereby improving the support stability of the bracket 100. At the same time, by providing the bottom arm 525, the first elastic member 52 can be fixedly connected to the movable seat 20 through its own structural shape (for example, the first connecting arm 523, the second connecting arm 524, and the bottom arm 525 are collectively embedded in the second groove 212), making assembly simple.

[0121] In other embodiments, the bracket 100 may not include the sleeve 51. The rotating shaft core 40 may not be fixed to the support member 30. In this case, the first cantilever 521 and the second cantilever 522 may directly abut the first groove wall 311 and the second groove wall 312 of the support member 30 respectively (please refer to the embodiment of FIG. Figure 10 When the support member 30 rotates relative to the movable seat 20, a large friction force can be generated between the first cantilever 521 and the first groove wall 311, and a large friction force can be generated between the second cantilever 522 and the second groove wall 312, thereby providing a torque for the support member 30 to rotate relative to the movable seat 20.

[0122] In other embodiments, the first elastic member 52 may not include the bottom arm 525. In this case, the end of the first connecting arm 523 facing away from the first cantilever 521 may be fixedly connected to the movable seat 20. The end of the second connecting arm 524 facing away from the second cantilever 522 may be fixedly connected to the movable seat 20.

[0123] In some other embodiments, the first torsion structure 50 may further include an elastic compression member (not shown). The elastic compression member may be sandwiched between the first cantilever 521 and the second cantilever 522. In this way, by providing the elastic compression member, the positive pressure of the first cantilever 521 on the first side wall 513 and the positive pressure of the second cantilever 522 on the second side wall 514 can be increased, thereby increasing the friction force that needs to be overcome when the support member 30 rotates relative to the movable seat 20. In other words, by providing the elastic compression member between the first cantilever 521 and the second cantilever 522, this embodiment is conducive to increasing the torque of the support member 30 when it rotates relative to the movable seat 20, thereby improving the user experience.

[0124] Figure 17 yes Figure 6The shown diagram is a partial cross-sectional structural diagram of an embodiment of the stent 100 cut along EE. Figure 18 yes Figure 17 The structure diagram of the bracket 100 shown is in an intermediate state from another perspective. Figure 19 yes Figure 17 The structure diagram of the bracket 100 shown is in an open state from another perspective.

[0125] like Figures 17 to 19 As shown, when the bracket 100 is in the closed state, the first protrusion 516 of the sleeve 51 can be located in the first groove 5212 of the first elastic member 52. The second protrusion 517 of the sleeve 51 can be located in the third groove 5222 of the first elastic member 52. At this time, the distance between the first cantilever 521 and the second cantilever 522 can be the first distance L1. It should be noted that the distance between the first cantilever 521 and the second cantilever 522 can be the distance between the first cantilever 521 and the first connecting arm 523 (please refer to the embodiment of the present invention). Figure 14 The end of the second cantilever 522 faces away from the second connecting arm 524 (please refer to Figure 14 The distance between the ends of the sleeve 51 along the axial direction of the sleeve 51.

[0126] For example, the bracket 100 may further include an intermediate state between the closed state and the open state. When the bracket 100 is in the intermediate state, the angle at which the support member 30 is opened relative to the movable seat 20 may be smaller than the angle at which the support member 30 is opened relative to the movable seat 20 when the bracket 100 is in the open state, and larger than the angle at which the support member 30 is opened relative to the movable seat 20 when the bracket 100 is in the closed state. For example, the angles at which the support member 30 is opened relative to the movable seat 20 when the bracket 100 is in the closed state, the intermediate state, and the open state may be 0°, 30°, and 60°, respectively.

[0127] For example, when the bracket 100 is in the intermediate state, in the axial direction of the sleeve 51, the first protrusion 516 of the sleeve 51 can directly face the first mating protrusion 5211 of the first elastic member 52, and the first protrusion 516 can press against the first mating protrusion 5211. The top of the first protrusion 516 can directly face the top of the first mating protrusion 5211. In the axial direction of the sleeve 51, the second protrusion 517 of the sleeve 51 can directly face the second mating protrusion 5221 of the first elastic member 52, and the second protrusion 517 can press against the second mating protrusion 5221. The top of the second protrusion 517 can directly face the top of the second mating protrusion 5221. At this time, the distance between the first cantilever 521 and the second cantilever 522 can be a second distance L2. The second distance L2 can be smaller than the first distance L1.

[0128] For example, when the bracket 100 is in the open state, the first protrusion 516 of the sleeve 51 can be located in the second groove 5213 of the first elastic member 52. The second protrusion 517 of the sleeve 51 can be located in the fourth groove 5223 of the first elastic member 52. At this time, the distance between the first cantilever 521 and the second cantilever 522 can be a third distance L3. The third distance L3 can be greater than the second distance L2.

[0129] Please refer again Figures 17 to 19 When the bracket 100 switches between the closed state and the open state, the connecting end 30a of the support member 30 can rotate relative to the movable seat 20, thereby driving the sleeve 51 to rotate relative to the movable seat 20. At this time, the first protrusion 516 of the sleeve 51 can slide relative to the first matching protrusion 5211 of the first elastic member 52, and the second protrusion 517 of the sleeve 51 can slide relative to the second matching protrusion 5221 of the first elastic member 52.

[0130] When the bracket 100 switches from the closed state to the intermediate state, the first protrusion 516 can slide relative to the first mating protrusion 5211 and squeeze the first mating protrusion 5211, causing the first cantilever 521 to move in a direction closer to the second cantilever 522 (for example, the first cantilever 521 tilts in a direction closer to the second cantilever 522). When the bracket 100 switches from the closed state to the intermediate state, the top of the first protrusion 516 can squeeze the top of the first mating protrusion 5211. The top of the second protrusion 517 can squeeze the top of the second mating protrusion 5221. At this time, the distance between the first cantilever 521 and the second cantilever 522 is minimized. The first side wall 513 of the sleeve 51 is subjected to the greatest elastic force from the first cantilever 521. The second side wall 514 of the sleeve 51 is subjected to the greatest elastic force from the second cantilever 522. At this time, if the support member 30 continues to open relative to the movable seat 20, the first protrusion 516 will pass over the top of the first mating protrusion 5211, and the second protrusion 517 will pass over the top of the second mating protrusion 5221. The distance between the first cantilever 521 and the second cantilever 522 will increase, and the first cantilever 521 and the second cantilever 522 will release their elastic force, allowing the first protrusion 516 and the second protrusion 517 to automatically slide into the second groove 5213 and the fourth groove 5223 respectively under the action of the first elastic member 52, so that the bracket 100 can automatically switch from the intermediate state to the open state.

[0131] Similarly, when the bracket 100 switches from the open state to the intermediate state, the first protrusion 516 can slide relative to the first mating protrusion 5211 and squeeze the first mating protrusion 5211, causing the first cantilever 521 to move in a direction closer to the second cantilever 522 (for example, the first cantilever 521 tilts in a direction closer to the second cantilever 522). When the bracket 100 switches from the closed state to the intermediate state, the top of the first protrusion 516 can squeeze the top of the first mating protrusion 5211. The top of the second protrusion 517 can squeeze the top of the second mating protrusion 5221. At this time, the distance between the first cantilever 521 and the second cantilever 522 is minimized. The first side wall 513 of the sleeve 51 is subjected to the maximum elastic force of the first cantilever 521. The second side wall 514 of the sleeve 51 is subjected to the maximum elastic force of the second cantilever 522. At this time, if the support member 30 continues to close relative to the movable seat 20, the first protrusion 516 will pass over the top of the first mating protrusion 5211, and the second protrusion 517 will pass over the top of the second mating protrusion 5221. The distance between the first cantilever 521 and the second cantilever 522 will increase, and the first cantilever 521 and the second cantilever 522 will release their elastic force, allowing the first protrusion 516 and the second protrusion 517 to automatically slide into the first groove 5212 and the third groove 5222 respectively under the action of the first elastic member 52, so that the bracket 100 can automatically switch from the intermediate state to the closed state.

[0132] It is understood that the sleeve 51 in this embodiment cooperates with the first mating protrusion 5211 of the first elastic member 52 by providing the first protrusion 516, so that when the support member 30 is opened relative to the movable seat 20 until the first protrusion 516 passes over the first mating protrusion 5211, the first protrusion 516 can automatically slide into the second groove 5213, so that the bracket can automatically switch from the intermediate state to the open state. In addition, when the support member 30 is closed relative to the movable seat 20 until the first protrusion 516 passes over the first mating protrusion 5211, the first protrusion 516 can automatically slide into the first groove 5212, so that the bracket can automatically switch from the intermediate state to the closed state. In other words, in this embodiment, by providing the first protrusion 516 and the first mating protrusion 5211, the bracket 100 can realize the self-opening and self-closing functions of the support member 30 relative to the movable seat 20, and the user experience is better.

[0133] In some embodiments, see Figure 19 and Figure 20 , Figure 20 yes Figure 6The bracket 100 shown is a schematic diagram of a partial cross-sectional structure of an embodiment when it is cut along DD and in an open state. When the bracket 100 is in the open state, the third side wall 515 of the sleeve 51 can contact a portion of the lower surface of the first elastic member 52, thereby achieving a stop position. For example, a stop block 518 can also be provided in the mounting groove 512 of the sleeve 51. The stop block 518 can be located between the first side wall 513 and the second side wall 514. The stop block 518 can be set toward the lower surface of the first elastic member 52. In this case, the surface of the stop block 518 facing the first elastic member 52 can constitute the third side wall 515 of the mounting groove 512.

[0134] Figure 21 yes Figure 6 The shown diagram is a partial cross-sectional structural diagram of the stent 100 taken along DD in some embodiments. Figure 22 yes Figure 21 The structure diagram of the fixing base 10 shown is from another perspective.

[0135] like Figure 21 and Figure 22 As shown, the fixing seat 10 may include a base plate 11 and a protrusion 12. The base plate 11 may include a first surface 111 and a second surface 112 disposed opposite to each other. The base plate 11 may be roughly in the shape of an annular plate. The protrusion 12 may be fixedly connected to the inner circumferential side surface of the base plate 11 and protrude relative to the first surface 111 of the base plate 11. The protrusion 12 may be roughly in the shape of a disc. The protrusion 12 may be provided with a receiving space 121. The bottom wall 1211 of the receiving space 121 of the protrusion 12 may face the base plate 11. The protrusion 12 may also be provided with a connecting hole 122. The connecting hole 122 may pass through the surface of the protrusion 12 facing away from the base plate 11 and be connected to the receiving space 121.

[0136] Exemplarily, the fixing base 10 may be provided with a first protrusion 13. The first protrusion 13 may be fixedly connected to the first surface 111 of the base plate 11. The first protrusion 13 may be located on the peripheral side of the protrusion 12. The first protrusion 13 may be fixedly connected to the peripheral side surface of the protrusion 12. The first protrusion 13 may include a first side surface 131 and a second side surface 132 disposed opposite to each other. The first side surface 131 may be disposed at an angle to the second side surface 132. The shape of the first protrusion 13 may be roughly a fan-shaped ring. Exemplarily, the first protrusion 13 may be flush with the protrusion 12.

[0137] It should be noted that, for ease of understanding, Figure 21In the following figures, the bottom plate 11, the protrusion 12, and the first protrusion 13 of the fixing base 10 are schematically demarcated by dotted lines. Although the fixing base 10 is divided into three parts (i.e., the bottom plate 11, the protrusion 12, and the first protrusion 13) in this embodiment, this does not affect the fixing base 10 being an integrally formed structure, i.e., the bottom plate 11, the protrusion 12, and the first protrusion 13 can be integrally formed.

[0138] Figure 23 yes Figure 6 The shown diagram is a partial cross-sectional structural diagram of a stent 100 in one embodiment cut along DD. Figure 24 yes Figure 6 The shown diagram is a partial cross-sectional structural diagram of an embodiment of the bracket 100 cut along CC. Figure 25 yes Figure 24 The structure diagram of the bracket 100 shown is when the movable seat 20 is in the second position.

[0139] like Figures 23 to 25 As shown, the main body 21 of the movable seat 20 may further be provided with a rotating column 213. The rotating column 213 may be located between the first groove 211 and the second groove 212. The central axis of the rotating column 213 may coincide with the first axis T1. For example, the first groove 211 may be an arc-shaped groove. The arc center of the first groove 211 may coincide with the first axis T1. In the circumferential direction around the first axis T1, the first groove 211 may include a first end wall 211a and a second end wall 211b that are arranged opposite to each other. It should be noted that, Figure 8 The rotating post 213 and the first end wall 211a and the second end wall 211b of the first groove 211 are also shown from another perspective. For example, the peripheral side surface of the rotating post 213 may have a second flat surface portion 2131 .

[0140] Exemplarily, the fixed seat 10 can be sleeved on the rotating column 213 of the movable seat 20. The fixed seat 10 can rotate around the rotating column 213 relative to the movable seat 20, that is, rotate around the first axis T1. Among them, the rotating column 213 can pass through the connecting hole 122 of the fixed seat 10. Part of the rotating column 213 can also extend into the receiving space 121 of the fixed seat 10. The bottom plate 11 of the fixed seat 10 can be stacked with the main body 21 of the movable seat 20. The bottom plate 11 can cover the opening of the first groove 211 and the opening of the second groove 212 of the movable seat 20. Part of the first elastic member 52 can be located between the main body 21 of the movable seat 20 and the bottom plate 11 of the fixed seat 10.

[0141] For example, the main body 21 of the movable seat 20 may further include an escape groove 214. The escape groove 214 may connect the first groove 211 and the second groove 212. The escape groove 214 may be used to avoid the protrusion 12 of the fixed seat 10. In this case, the protrusion 12 may be located on the side of the bottom arm 525 of the first elastic member 52 facing away from the first connecting arm 523. Part of the outer peripheral sidewall of the protrusion 12 may also be considered as the groove sidewall of the first groove 211 and / or the second groove 212. The bottom arm 525 may be generally arc-shaped. The arc center of the bottom arm 525 may coincide with the first axis T1. The outer peripheral sidewall of the protrusion 12 may be adapted to the shape of the bottom arm 525. The outer peripheral sidewall of the protrusion 12 may contact the bottom arm 525, or there may be a gap between the bottom arm 525. In this way, when the movable seat 20 and the fixed seat 10 rotate relative to each other, the protrusion 12 and the bottom arm 525 will not interfere with each other and affect the movement of the movable seat 20. In some embodiments, the fixing base 10 may not include the protrusion 12 .

[0142] For example, the first protrusion 13 of the fixed seat 10 can be located within the first groove 211 of the movable seat 20. When the movable seat 20 rotates relative to the fixed seat 10, the first protrusion 13 can slide between the first end wall 211a and the second end wall 211b relative to the bottom wall of the first groove 211. The distance between the first end wall 211a and the second end wall 211b of the first groove 211 can be greater than the size of the first protrusion 13. The angle formed between the first end wall 211a and the second end wall 211b can be greater than the angle formed between the first side surface 131 and the second side surface 132. The first side surface 131 can be positioned closer to the first end wall 211a than the second side surface 132. It should be noted that the distance between the first end wall 211a and the second end wall 211b can be the distance between the first end wall 211a and the second end wall 211b along the circumferential direction of the first axis T1. The size of the first bump 13 may be a size between the first side surface 131 and the second side surface 132 of the first bump 13 along the circumferential direction of the first axis T1 .

[0143] For example, when the movable seat 20 rotates relative to the fixed seat 10 to the first position (eg Figure 24 As shown in FIG. 1 , the first side surface 131 of the first protrusion 13 can abut against the first end wall 211a of the first groove 211. The second side surface 132 can be spaced apart from the second end wall 211b. When the movable seat 20 rotates relative to the fixed seat 10 to the second position (as shown in FIG. 1 ), the first side surface 131 of the first protrusion 13 can abut against the first end wall 211a of the first groove 211. Figure 25As shown in FIG. 2 , the second side surface 132 of the first protrusion 13 can abut the second end wall 211b of the first groove 211. The first side surface 131 can be spaced apart from the first end wall 211a. For example, when the movable seat 20 is in the first position, the angle formed between the second side surface 132 of the first protrusion 13 and the second end wall 211b of the first groove 211 can be 90°. That is, when the movable seat 20 switches from the first position to the second position, the movable seat 20 can rotate 90° relative to the fixed seat 10.

[0144] It is understood that in this embodiment, the movable seat 20 is provided with a first groove 211, and the fixed seat 10 is provided with a first protrusion 13. When the movable seat 20 rotates relative to the fixed seat 10, the first protrusion 13 can slide between the two end walls (i.e., the first end wall 211a and the second end wall 211b in this embodiment) of the first groove 211, which are arranged along the circumferential direction of the first axis T1, until the first protrusion 13 contacts one of the end walls, thereby achieving a rotation stop for the movable seat 20. In this way, through the cooperation between the first protrusion 13 and the first groove 211, the movable seat 20 can be stopped when rotating to different angles relative to the fixed seat 10. When the user operates the support member 30 to drive the movable seat 20 to rotate relative to the fixed seat 10, the feel of the movable seat 20 in a specific position (i.e., the first position and the second position in this embodiment) can be improved, allowing the user to accurately operate the movable seat 20 to rotate to a specific position, thereby improving the user experience.

[0145] Secondly, when the movable seat 20 is switched from the first position to the second position, the movable seat 20 can rotate 90° relative to the fixed seat 10. When the bracket 100 is used in the electronic device 1000, the bracket 100 can better support the vertical screen display and horizontal screen display of the electronic device 1000. For example, when the movable seat 20 is in the first position, the bracket 100 can be used to support the vertical screen display of the electronic device 1000; when the movable seat 20 is in the second position, the bracket 100 can be used to support the horizontal screen display of the electronic device 1000. In this way, through the cooperation of the first protrusion 13 and the first groove 211, the user can switch the movable seat 20 from the first position to the second position, or switch the movable seat 20 from the second position to the first position more quickly and accurately, so as to quickly realize the switching of the electronic device 1000 between different postures and enhance the user experience.

[0146] In other embodiments, the positions of the first protrusion 13 and the first groove 211 can be interchanged, that is, the first protrusion 13 can also be fixedly connected to the main body 21 of the movable seat 20, and the first groove 211 can also be formed on the side of the fixed seat 10 facing the movable seat 20.

[0147] Figure 26 yes Figure 7The second torsion structure 60 and the fastener 70 are schematic exploded views in some embodiments. Figure 27 yes Figure 6 The cross-sectional structure diagram of the bracket 100 in one embodiment is shown along CC. Figure 28 yes Figure 6 The cross-sectional structure diagram of the bracket 100 in one embodiment is shown along DD.

[0148] like Figures 26 to 28 As shown, the bracket 100 may further include a second torsion structure 60. The second torsion structure 60 may be used to provide torque when the movable base 20 rotates relative to the fixed base 10, thereby improving the user experience. For example, the second torsion structure 60 may include a second elastic member 61, a cam ring 62, and a gasket 63.

[0149] Exemplarily, the cam ring 62 may include an upper surface 62a and a lower surface 62b disposed opposite each other. The cam ring 62 may be generally annular. The cam ring 62 may have a first fixing hole 621. The first fixing hole 621 may extend through the upper surface 62a and the lower surface 62b of the cam ring 62 and be sleeved onto the rotating column 213 of the movable seat 20. In this case, the cam ring 62 may be located on the side of the protrusion 12 of the fixed seat 10 facing away from the movable seat 20, and within the receiving space 121 of the protrusion 12. The upper surface 62a of the cam ring 62 may face the protrusion 12. A third mating flat surface 6211 may be provided on the inner surface of the first fixing hole 621. The third mating flat surface 6211 may be disposed facing the second flat surface 2131 of the rotating column 213. Thus, the mating of the third mating flat surface 6211 with the second flat surface 2131 prevents relative rotation between the cam ring 62 and the rotating column 213. In other words, when the movable seat 20 rotates relative to the fixed seat 10, the movable seat 20 can drive the cam ring 62 to rotate relative to the fixed seat 10. In other embodiments, the cam ring 62 may not include the third mating flat portion 6211. The cam ring 62 may also be fixedly connected to the rotating column 213 through other means (such as keyway engagement).

[0150] Exemplarily, the gasket 63 can be roughly annular. The gasket 63 can have a second fixing hole 631. The second fixing hole 631 can be sleeved on the rotating column 213. The gasket 63 can be located on the side of the lower surface 62b of the cam ring 62 facing away from the upper surface 62a, and is located in the receiving space 121. Among them, the inner side surface of the second fixing hole 631 can be provided with a fourth mating plane portion 6311. The fourth mating plane portion 6311 can be arranged facing the second plane portion 2131 of the rotating column 213. In this way, through the cooperation between the fourth mating plane portion 6311 and the second plane portion 2131, relative rotation will not occur between the gasket 63 and the rotating column 213. In other words, when the movable seat 20 rotates relative to the fixed seat 10, the movable seat 20 can drive the gasket 63 to rotate relative to the fixed seat 10.

[0151] For example, the second elastic member 61 can be generally annular. The second elastic member 61 can be a disc spring. The second elastic member 61 can be sleeved around the rotating column 213 and positioned within the receiving space 121. The second elastic member 61 can be positioned between the cam ring 62 and the gasket 63. In this case, a portion of the cam ring 62, the second elastic member 61, and a portion of the gasket 63 can be stacked within the receiving space 121. In other embodiments, the second elastic member 61 can also be another elastic element, such as a coil spring.

[0152] Exemplarily, the bracket 100 may further include a fastener 70. The fastener 70 may be a bolt. The rotating column 213 may further be provided with a mounting hole 213a. The axial direction of the mounting hole 213a may be parallel to the first axis T1. The fastener 70 may include a screw 71 and a nut 72 that are fixedly connected. The screw 71 of the fastener 70 may be mounted in the mounting hole 213a, and a portion of the nut 72 of the fastener 70 may extend outside the rotating column 213 and be located on the side of the gasket 63 facing away from the cam ring 62. When the screw 71 of the fastener 70 is locked with the rotating column 213, the nut 72 of the fastener 70 may squeeze the gasket 63 along the axial direction of the rotating column 213. Under the action of the fastener 70, the gasket 63 may squeeze the second elastic member 61, and the second elastic member 61 may squeeze the cam ring 62. Under the action of the second elastic member 61 , the cam ring 62 can abut against the protrusion 12 of the fixed seat 10 , and the protrusion 12 can abut against the main body 21 of the movable seat 20 .

[0153] It can be understood that in this embodiment, by providing a second elastic member 61 on the side of the fixed seat 10 facing away from the movable seat 20, and providing a fastener 70 to lock with the movable seat 20 in a direction parallel to the first axis T1, the fastener 70 can squeeze the second elastic member 61 in a direction parallel to the first axis T1, and the second elastic member 61 can squeeze the movable seat 20 under the action of the fastener 70, so that the movable seat 20 can abut against the fixed seat 10. In other words, the movable seat 20 can be subjected to positive pressure from the second elastic member 61. In this way, when the movable seat 20 rotates relative to the fixed seat 10, a large friction force can be generated between the movable seat 20 and the fixed seat 10, thereby hindering the rotation of the movable seat 20 relative to the fixed seat 10. In other words, the second elastic member 61 can cooperate with the fastener 70 to provide torque for the rotation of the movable seat 20 relative to the fixed seat 10, thereby improving the user experience.

[0154] Secondly, the fixed base 10 in this embodiment is provided with a protrusion 12, which is located on the side of the base plate 11 facing the movable base 20. The second elastic member 61 can be accommodated within the receiving space 121 of the protrusion 12. The protrusion 12 can be protruding into the movable base 20, so that the protrusion 12 and the second elastic member 61 located in the receiving space 121 can both utilize the thickness of the movable base 20, thereby facilitating a reduction in the overall thickness of the bracket 100 and achieving a thinner design for the bracket 100.

[0155] In addition, the second torsion structure 60 in this embodiment may further include a washer 63. The washer 63 may abut between the second elastic member 61 and the nut 72 of the fastener 70. The fastener 70 may compress the washer 63, thereby causing the washer 63 to compress the second elastic member 61. In this way, the fastener 70 indirectly compresses the second elastic member 61 through the washer 63, allowing the second elastic member 61 to be positioned freely without being restricted by the size of the fastener 70.

[0156] Please refer again Figure 26 and Figure 27, a first avoidance groove 632 may be provided on the side of the gasket 63 facing away from the cam ring 62. A second avoidance groove 633 may be provided on the side of the gasket 63 facing the cam ring 62. The first avoidance groove 632 is arranged closer to the rotating column 213 than the second avoidance groove 633. One of the openings of the first avoidance groove 632 may face the rotating column 213. The first avoidance groove 632 may be used to avoid the nut 72 of the fastener 70. The second elastic member 61 may be located in the second avoidance groove 633 and abut between the lower surface 62b of the cam ring 62 and the gasket 63. In this way, the first avoidance groove 632 is provided on the side of the gasket 63 facing away from the cam ring 62 to avoid the nut 72 of the fastener 70, so that the fastener 70 can be accommodated inside the fixing base 10 without protruding relative to the fixing base 10, which is conducive to ensuring the smoothness of the appearance of the bracket 100. Secondly, the gasket 63 is further provided with a second avoidance groove 633 to accommodate the second elastic member 61 , so that the second elastic member 61 and the gasket 63 are arranged more compactly, which is beneficial to reducing the thickness of the bracket 100 and realizing a thinner setting of the bracket 100 .

[0157] Figure 29 yes Figure 28 The structure diagram of the bracket 100 shown is when the movable seat 20 is in the third position.

[0158] like Figure 26 、 Figure 28 as well as Figure 29 As shown, the bottom wall 1211 of the receiving space 121 (please refer to Figure 22 As shown) a third groove 123 may be provided. It should be understood that Figure 22 and Figure 24 The third groove 123 is also illustrated from another perspective. The cam ring 62 may also include a second protrusion 623. The second protrusion 623 may be fixedly connected to the upper surface 62a of the cam ring 62. When the movable seat 20 switches between the first position and the second position, the movable seat 20 can drive the cam ring 62 to rotate relative to the fixed seat 10. At this time, the second protrusion 623 of the cam ring 62 can slide into or out of the third groove 123 of the protrusion 12. Among them, the movable seat 20 can be rotated to the third position relative to the fixed seat 10 so that the second protrusion 623 slides into the third groove 123. When the second protrusion 623 slides out of the third groove 123, it needs to overcome a greater torque than when the second protrusion 623 slides into the third groove 123. In this way, through the cooperation between the second protrusion 623 and the third groove 123, the movable seat 20 can achieve self-locking at a specific position (that is, the third position in this embodiment) during the rotation relative to the fixed seat 10, thereby improving the user experience. It should be noted that, Figure 29 The second protrusion 623 blocked by the fixing base 10 is indicated by a dotted line.

[0159] In other embodiments, the positions of the third groove 123 and the second protrusion 623 can be interchanged, that is, the second protrusion 623 can be fixed to the bottom wall 1211 of the receiving space 121 , and the third groove 123 can be formed on the upper surface 62 a of the cam ring 62 .

[0160] In some other embodiments, the second torsion structure 60 may not include the cam ring 62 . In this case, one side of the second elastic member 61 may directly abut against the fixing seat 10 .

[0161] Figure 30 yes Figure 6 The structure of the bracket 100 shown in another embodiment is schematically shown. Figure 31 yes Figure 30 The structure diagram shown is when the bracket 100 is in the open state and the movable seat 20 is in the first position. Figure 32 yes Figure 30 The structure diagram shown is when the bracket 100 is in the open state and the movable seat 20 is in the second position.

[0162] like Figures 30 to 32 As shown, the structure of the bracket 100 in this embodiment is similar to Figure 6 The structure of the bracket 100 shown is roughly the same. Among them, the connecting end 30a of the support member 30 can be rotatably connected to the movable seat 20, and can rotate relative to the movable seat 20 around the first axis T1, so that the supporting end 30b of the support member 30 can be opened or closed relative to the movable seat 20. The movable seat 20 can be rotatably connected to the fixed seat 10, and can rotate relative to the fixed seat 10 around the second axis T2 to change the position of the movable seat 20. The remaining identical parts will not be repeated. The bracket 100 and the bracket 100 in this embodiment will be described below. Figure 6 Various features of the stent 100 are shown.

[0163] Figure 33 yes Figure 30 The illustrated schematic diagram is an exploded structural diagram of the stent 100 in some embodiments. Figure 34 yes Figure 30 The shown diagram is a partial cross-sectional structural diagram of an embodiment of the bracket 100 cut along FF. Figure 35 yes Figure 30 The shown diagram is a partial cross-sectional structural diagram of an embodiment of the bracket 100 cut along GG.

[0164] like Figures 33 to 35As shown, the main body 21 of the movable seat 20 may include a first portion 215 and a second portion 216. A portion of the second portion 216 may be fixedly connected to the first portion 215, and a portion of the second portion 216 may form an installation gap 217 with the first portion 215. The mounting portion 22 of the movable seat 20 may have a second notch 222. The second notch 222 may be used to mount the support end 30b of the support member 30.

[0165] For example, the first torsion structure 50 may include a first sleeve 53. The first sleeve 53 may include a first mounting plate 531, a first enclosing circle 532, and a second enclosing circle 533, which are fixedly connected. The first enclosing circle 532 and the second enclosing circle 533 may be located on the same side of the first mounting plate 531. The first enclosing circle 532 may be spaced apart from the second enclosing circle 533. The first mounting plate 531 may be located within the mounting gap 217 and fixedly connected to the second portion 216 of the movable seat 20. In this case, the first enclosing circle 532 and the second enclosing circle 533 may both be located in the second notch 222 of the mounting portion 22. The first enclosing circle 532 may have a first mounting hole 532a. The second enclosing circle 533 may have a second mounting hole 533a. The first mounting hole 532a may be positioned opposite the second mounting hole 533a.

[0166] For example, the first torsion structure 50 may further include a second sleeve 54. The second sleeve 54 may include a second mounting plate 541 and a third enclosing ring 542 that are fixedly connected. The second mounting plate 541 may be fixedly connected to the connecting end 30a of the support member 30. The third enclosing ring 542 may be located within the first notch 31 of the support member 30 and spaced apart from the first groove wall 311 and the second groove wall 312 of the first notch 31. The third enclosing ring 542 may define a third mounting hole 542a. The third mounting hole 542a may be positioned opposite the first connecting hole 113 and the connecting hole 122.

[0167] Exemplarily, the rotating shaft core 40 may include two shaft cores, for example, a first shaft core 44 and a second shaft core 45. The first shaft core 44 may be inserted into the first mounting hole 532a of the first enclosing circle 532. The two ends of the first shaft core 44 may be inserted into the first connecting hole 113 of the support member 30 and the third mounting hole 542a of the second sleeve 54, respectively, to securely connect the support member 30 and the second sleeve 54. The first shaft core 44 may have an interference fit with the first mounting hole 532a of the first enclosing circle 532. The second shaft core 45 may be inserted into the second mounting hole 533a of the second enclosing circle 533. The two ends of the second shaft core 45 may be inserted into the connecting hole 122 of the support member 30 and the third mounting hole 542a of the second sleeve 54, respectively, to securely connect the support member 30 and the second sleeve 54. The second shaft core 45 may have an interference fit with the second mounting hole 533a of the second enclosing circle 533. At this point, the connection end 30a of the support member 30 can be positioned within the second notch 222 of the mounting portion 22 of the movable seat 20. The support member 30 can drive the rotating shaft core 40 to rotate relative to the first shaft sleeve 53 about the first axis T1, and thus relative to the movable seat 20 about the first axis T1. The first axis T1 can coincide with the central axis of the rotating shaft core 40. The first shaft core 44 and the second shaft core 45 can respectively cooperate with the first and second encircling circles 532 and 533 to provide torque when the support member 30 rotates relative to the movable seat 20.

[0168] In some embodiments, the bracket 100 may further include a first shielding member 81. The first shielding member 81 may be fixedly connected to the support member 30 and cover the connection between the support member 30 and the first sleeve 53. It should be understood that Figure 32 The first shielding member 81 is also shown from another perspective. In this way, the first shielding member 81 can prevent the first sleeve 53 from being exposed, thereby ensuring the appearance consistency of the support member 30 and improving the appearance refinement of the bracket 100.

[0169] Figure 36 yes Figure 30 The cross-sectional structure diagram of the bracket 100 in one embodiment is shown along FF.

[0170] like Figure 33 and Figure 36 As shown, the bottom plate 11 of the fixing base 10 can be roughly in the shape of an elongated plate. The protrusion 12 of the fixing base 10 can be roughly in the shape of a circular ring. In this case, the receiving space 121 of the protrusion 12 can be roughly cylindrical. The bottom wall 1211 of the receiving space 121 of the protrusion 12 can be arranged away from the bottom plate 11. The connecting hole 122 of the protrusion 12 can pass through the bottom wall 1211 of the receiving space 121 and connect to the receiving space 121. The radial dimension of the connecting hole 122 can be smaller than the radial dimension of the receiving space 121.

[0171] For example, the protrusion 12 of the fixed base 10 can be positioned within the avoidance groove 214 of the movable base 20. At least a portion of the rotation column 213 can be positioned within the receiving space 121 of the protrusion 12. The rotation column 213 can be positioned directly opposite the connection hole 122 of the fixed base 10. In this case, the fastener 70 can pass through the connection hole 122 of the fixed base 10 and be locked with the rotation column 213. The movable base 20 can drive the fastener 70 to rotate relative to the fixed base 10 about the first axis T1. The first axis T1 can coincide with the central axis of the mounting hole 213a.

[0172] Illustratively, the second torsion structure 60 may include a second elastic member 61. The second elastic member 61 may be a damping ring. At least a portion of the second elastic member 61 may be disposed within the receiving space 121 of the protrusion 12, abutting between the outer wall of the rotating column 213 and the inner wall of the protrusion 12. The second elastic member 61 may form an interference fit with the outer wall of the rotating column 213 and the inner wall of the protrusion 12. In this way, the second elastic member 61 can provide torsional force when the movable base 20 rotates relative to the fixed base 10, thereby improving the user experience.

[0173] For example, the second torsion structure 60 may further include a third elastic member 64. The third elastic member 64 may be a disc spring. The third elastic member 64 may abut between the surface of the protrusion 12 facing away from the base plate 11 and the movable seat 20. In this way, the third elastic member 64 can reduce the assembly gap between the fixed seat 10 and the movable seat 20, making the structure of the fixed seat 10 and the movable seat 20 more compact.

[0174] In some embodiments, the projections of the movable seat 20 and the support member 30 on the plane where the bottom plate 11 of the fixed seat 10 is located can cover at least a portion of the bottom plate 11. At least one magnetic element 82 can be embedded in the bottom plate 11. The bracket 100 can also include a second shielding member 83. The second shielding member 83 can be used to cover the portion of the bottom plate 11 where the magnetic element 82 is embedded to ensure the appearance consistency of the bracket 100. It can be understood that this embodiment fixes the fixed seat 10 to the electronic device 1000 by providing a magnetic element 82 in the fixed seat 10 to cooperate with the magnetic part in the electronic device 1000. Compared to Figure 6 In the illustrated embodiment of the bracket 100, the base plate 11 is larger in size, and multiple magnetic elements 82 can be disposed within the base plate 11, thereby effectively increasing the magnetic attraction between the mounting base 10 and the electronic device 1000 and improving the connection reliability between the two. In other embodiments, the base plate 11 can also be a magnetic element.

[0175] In some embodiments, the surface of the base plate 11 facing the movable seat 20 can be partially recessed inward to form an escape space 11a. The protrusion 12 can be located in the escape space 11a. The escape space 11a can be used to escape the movable seat 20 and the support member 30. Among them, the movable seat 20 can be located in the escape space 11a. When the bracket 100 is in a closed state and the movable seat 20 is in the first position, the support member 30 can also be located in the escape space 11a and stacked with the base plate 11. At this time, the projection of the movable seat 20 and the support member 30 on the plane where the base plate 11 is located can cover part of the base plate 11. Part of the base plate 11 can be flush with the movable seat 20 and the support member 30. In this way, the plane size of the base plate 11 is larger, and can accommodate multiple magnetic elements 82 or larger magnetic elements 82, thereby improving the fixing stability between the bracket 100 and other components (such as the device housing 200). At the same time, the movable seat 20 and the support member 30 can also be located in the avoidance space 11a of the base plate 11. On the one hand, the thickness of the fixed seat 10 can be utilized to reduce the overall thickness of the bracket 100; on the other hand, part of the base plate 11 can be flush with the movable seat 20 and the support member 30, thereby ensuring the appearance of the bracket 100 and improving the user experience.

[0176] Figure 37 Schematic diagram of the structure of the stent 900 provided in the present application in some embodiments when the stent is in a closed state. Figure 38 yes Figure 37 The structure diagram of the bracket 900 shown is when it is in the first open state. Figure 39 yes Figure 37 The structure diagram of the bracket 900 shown is in the second open state. Figure 40 yes Figure 37 The cross-sectional structure diagram of the bracket 900 in one embodiment is shown along HH.

[0177] like Figures 37 to 40 As shown, the bracket 900 in this embodiment may include a fixed base 910, a first support member 920 and a second support member 930. The fixed base 910 may include a base plate 911 and a boss 912 protruding from the base plate 911. The first support member 920 can be rotatably connected to the boss 912 and can rotate relative to the boss 912 around a first axis Q1. The second support member 930 can be rotatably connected to the base plate 911 and can rotate relative to the base plate 911 around a second axis Q2. The first axis Q1 can be perpendicular to the second axis Q2. In this way, by providing two support members 30 (i.e., the first support member 920 and the second support member 930 in this embodiment) that are respectively rotatably connected to different positions of the fixed base 910, so as to rotate in different directions relative to the fixed base 910, the bracket 900 can have two different tilt postures to meet the user's usage needs in different scenarios.

[0178] For example, the bracket 900 may further include a first rotating shaft core 940. The first support member 920 may be rotatably connected to the boss 912 via the first rotating shaft core 940. The first rotating shaft core 940 may include a first shaft core 941 and a second shaft core 942. The bracket 900 may further include a first torsion structure 950. The first torsion structure 950 may be used to provide torsion when the first support member 920 rotates relative to the boss 912. The arrangement of the first torsion structure 950 is similar to the embodiment of the present invention. Figure 33 The setting of the first torsion structure 50 of the bracket 100 shown is roughly the same or similar. For example, the first torsion structure 950 can also include a first sleeve 951 and a second sleeve 952. The first sleeve 951 can be fixedly connected to the fixed seat 10, and part of the first sleeve 951 is rotatably connected to the first rotating axis core 940 and interferes with the first rotating axis core 940. The second sleeve 952 can be fixedly connected to the first support member 920 and the first rotating axis core 940. The remaining identical parts will not be repeated.

[0179] For example, the bracket 900 may further include a second rotation axis 960. The second support member 930 may be provided with a mounting hole 931. The base plate 911 may be provided with a mating hole 9111. The second rotation axis 960 may be inserted into the mounting hole 931 and the mating hole 9111 to allow the second support member 930 to be rotatably connected to the base plate 911. The second rotation axis 960 may have an interference fit with the mating hole 9111. In this way, the second rotation axis 960 may cooperate with the mating hole 9111 to provide a torsional force when the second support member 930 rotates relative to the base plate 911.

[0180] In some embodiments, the second support member 930 may have an escape space 932. When the bracket 900 is in the closed state, the escape space 932 can be used to accommodate the boss 912 and the first support member 920. This helps reduce the thickness of the bracket 900 in the closed state, thereby facilitating a thinner configuration of the bracket 900.

[0181] It should be noted that, in the absence of conflict, the features in the embodiments of this application can be combined with each other, and any combination of features in different embodiments is also within the scope of protection of this application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0182] It should be noted that all the above drawings are for illustrative purposes only and do not represent the actual size of the product. Furthermore, the dimensional ratios between the components in the drawings are not intended to limit the actual product of the present application.

[0183] The above are only some of the embodiments of this application, and the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
