Description

Protective casing and terminal components

[0001] This application claims priority to Chinese Patent Application No. 202421808284.2, filed on July 26, 2024, entitled “Protective Shell and Terminal Component”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of protective case technology, and more particularly to a protective case and terminal component. Background Technology

[0003] Phone cases are primarily used for protection and decoration of mobile phones. To further enhance the practicality of phone cases, a stand has been added to the back. This stand frees the user's hands and helps to fix the phone at a suitable angle and height for easy viewing of the screen.

[0004] In existing technology, phone case stands are generally rotatable, facilitating portrait or landscape placement of the phone. However, after prolonged use or under external force, the stand can easily rotate relative to the phone, causing changes in the phone's angle and height. This requires the user to readjust the stand, reducing the user experience.

[0005] Therefore, how to increase the support of the stand for the mobile phone and prevent the stand from easily rotating relative to the mobile phone is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] This application provides a protective case designed to solve the problem that the stand is prone to rotating relative to the mobile phone in the prior art, and to improve the support of the stand for the mobile phone.

[0007] In a first aspect, embodiments of this application provide a protective shell, the protective shell including a shell body, a fixing part, and a bracket. The shell body includes a first surface and a second surface, the first surface and the second surface being disposed opposite to each other along the thickness direction of the shell body. The fixing part includes a fixing plate, the fixing plate protruding from the first surface and fixedly connected to the shell body, the fixing plate having a sliding groove facing away from the first surface, the sliding groove including a first limiting wall. The bracket includes a first support part and a second support part, the first support part including a first support body and a slider, the slider being fixedly connected to the first support body, the first support part being disposed on the first surface, and the first support body covering the fixing plate, the slider being slidably connected to the sliding groove. The second support part includes a second support body, one end of the second support body being rotatably connected to one end of the first support body, the second support body being able to open at an angle relative to the first support body or the second support body being able to conform to the surface of the first support body facing away from the shell body. The slider can slide along the groove, causing the first support and the second support to rotate relative to the shell body. The slider can abut against the first limiting wall, and the torque of the first supporting force of the first limiting wall on the slider is opposite to the torque of the first supporting force on the second support.

[0008] In summary, the protective case provided in this application embodiment allows the slider to abut against the first limiting wall when the mobile terminal is placed vertically on an object, and the torque of the first holding force of the first limiting wall on the slider is opposite to the torque of the first supporting force of the object on the second supporting part, thus preventing the bracket from rotating relative to the mobile terminal when the mobile terminal is placed vertically and enhancing the support of the bracket for the mobile terminal.

[0009] In one embodiment, the slide is an arc-shaped groove extending around the centerline of the fixed disk, which is parallel to the thickness direction of the shell body. The slide further includes a second limiting wall, which, along with the first limiting wall, represents two walls along the extension direction of the slide. The slider can abut against the second limiting wall, and the torque of the second holding force exerted by the second limiting wall on the slider is opposite to the torque of the second supporting force exerted on the second support portion. When the mobile terminal is placed horizontally on an object, the slider abuts against the second limiting wall, and the torque of the second holding force exerted by the second limiting wall on the slider is opposite to the torque of the second supporting force exerted by the object on the second support portion. This prevents the first and second support portions from rotating relative to the mobile terminal when the mobile terminal is horizontally positioned, thus enhancing the support of the bracket for the mobile terminal.

[0010] In one embodiment, the sidewall of the slide is arc-shaped, with an arc angle greater than 270 degrees and less than 360 degrees. From the point where the slider abuts against the first limiting wall to the point where the slider abuts against the second limiting wall, the slider needs to rotate 270 degrees.

[0011] In one embodiment, the fixing plate has a hollow portion, the first limiting wall has a first opening, and the second limiting wall has a second opening. The hollow portion communicates with the first opening and the second opening, respectively. The fixing portion further includes a supporting member disposed within the hollow portion. The supporting member includes a first supporting surface and a second supporting surface disposed opposite to each other. The first supporting surface is located at the first opening, and the first limiting wall is flush with the first supporting surface. The second supporting surface is located at the second opening, and the second limiting wall is flush with the second supporting surface. When the slider abuts against the first limiting wall, the slider also abuts against the first supporting surface. When the slider abuts against the second limiting wall, the slider also abuts against the second supporting surface. The supporting member is used to share the force exerted by the slider on the first limiting wall, preventing the slider from damaging or scratching the first limiting wall. When the slider abuts against the second limiting wall, the slider also abuts against the second supporting surface. The supporting member is also used to share the force of the slider on the second limiting wall, so as to prevent the slider from damaging or scratching the second limiting wall.

[0012] In some embodiments, the hollowed-out portion includes a first hollowed-out sub-portion, a second hollowed-out sub-portion, and a third hollowed-out sub-portion. The first hollowed-out sub-portion is disposed near the first limiting wall, and the first limiting wall exposes the first hollowed-out sub-portion. The second hollowed-out sub-portion is disposed near the second limiting wall, spaced apart from the first hollowed-out sub-portion, and the second limiting wall exposes the second hollowed-out sub-portion. The third hollowed-out sub-portion is disposed between the first hollowed-out sub-portion and the second hollowed-out sub-portion, and the third hollowed-out sub-portion communicates with both the second hollowed-out sub-portion and the first hollowed-out sub-portion.

[0013] The supporting member includes a first supporting sub-member, a second supporting sub-member, and a third supporting sub-member. The first supporting sub-member includes a first supporting surface, and the second supporting sub-member includes a second supporting surface. The opposite ends of the third supporting sub-member are respectively connected to the first supporting sub-member and the second supporting sub-member. The first supporting sub-member is disposed within the first hollow sub-section, the second supporting sub-member is disposed within the second hollow sub-section, and the third supporting sub-member is disposed within the third hollow sub-section.

[0014] In some embodiments, the inner wall of the third hollowed-out sub-part has multiple recesses, and the surface of the third abutment sub-part also has multiple protrusions, with each protrusion disposed within one of the recesses. By having the protrusions disposed within the recesses, the connection between the third abutment sub-part and the fixing plate can be enhanced, thereby strengthening the connection between the abutment and the fixing plate.

[0015] In one embodiment, the first support portion further includes a scratch-resistant member, which protrudes from the first support body and is spaced apart from the slider. The scratch-resistant member contacts the first surface, thus spacing the first support body from the shell body. The scratch-resistant member is rotatable relative to the shell body. The scratch-resistant member serves to separate the first support body from the shell body, preventing direct contact between the first support body and the shell body. When the first support portion rotates relative to the shell body, it prevents the first support portion from scratching the shell body or the shell body from scratching the first support portion.

[0016] In one embodiment, the first support body has a receiving groove, the opening of which faces the shell body. The fixing plate is disposed within the receiving groove, and the slider is fixedly connected to the bottom wall of the receiving groove, the opening of which faces the bottom wall of the receiving groove. The first support body has the receiving groove for accommodating the fixing plate, which allows the first support body to protect the fixing plate and also reduces the overall thickness of the fixing part and the bracket.

[0017] In one embodiment, the fixing disk has a mounting groove, the opening of which faces the bottom wall of the receiving groove, and the mounting groove is spaced apart from the sliding groove. The fixing part further includes a flexible member disposed within the mounting groove. The flexible member is either fixedly connected to the fixing disk or slidably connected to the bottom wall of the receiving groove; or, the flexible member is slidably connected to the fixing disk and fixedly connected to the bottom wall of the receiving groove. The flexible member is connected to both the fixing disk and the first support body, and the flexible member increases the frictional force that the first support body needs to overcome when rotating relative to the fixing disk, preventing minor external forces from causing the first support part and the second support part to rotate.

[0018] In one embodiment, the first support portion further includes a damping member, which is fixed to the side wall of the receiving groove and located on the outer periphery of the fixed disk. The damping member is spaced apart from the slider, elastically abuts against the fixed disk, and is rotatable around the outer periphery of the fixed disk. The elastic abutment between the damping member and the fixed disk prevents minor external forces from causing the first and second support portions to rotate.

[0019] In one embodiment, the damping element includes a first damping body, a second damping body, a third damping body, a fourth damping body, and a fifth damping body, which are sequentially connected. The first damping body is connected to the sidewall of the receiving groove and is spaced apart from the fixed plate. The fourth damping body is connected to the sidewall of the receiving groove and is spaced apart from the fixed plate. The fifth damping body is connected to the sidewall of the receiving groove and is spaced apart from the fixed plate. The second damping body is spaced apart from the sidewall of the receiving groove and elastically abuts against the fixed plate. The third damping body is spaced apart from the sidewall of the receiving groove and elastically abuts against the fixed plate. By fixing the first, fourth, and fifth damping bodies to the sidewall of the receiving groove, the damping element is fixed to the sidewall of the receiving groove. By spacing the second damping body and the third damping body from the sidewall of the receiving groove, the second damping body and the third damping body have a certain deformation space, so that the damping member elastically abuts against the fixed plate.

[0020] In one embodiment, the first damping body and the fourth damping body are arranged opposite to each other and spaced apart along the width direction of the first support body; the first damping body and the fifth damping body are arranged opposite to each other and spaced apart along the width direction of the first support body; and the second damping body and the third damping body are arranged opposite to each other and spaced apart along the length direction of the first support body. The opposite arrangement of the first and fourth damping bodies, and the opposite arrangement of the first and fifth damping bodies, makes the connection between the damping element and the sidewall of the receiving groove more stable. The opposite arrangement of the second and third damping bodies, which are elastically clamped to the fixed plate respectively, makes the elastic contact between the damping element and the fixed plate more stable.

[0021] In one embodiment, the shell body has a first mounting hole penetrating the first surface and the second surface, and the fixing disk has a second mounting hole penetrating the fixing disk. The second mounting hole communicates with the first mounting hole, and the center line of the second mounting hole is aligned with the center line of the first mounting hole. The first support portion further includes a connector, which is fixedly connected to the bottom wall of the receiving groove. The connector is spaced apart from the slider and is disposed within the first mounting hole and the second mounting hole. The connector is rotatable relative to the first mounting hole and the second mounting hole. By disposing the connector within the first mounting hole and the second mounting hole, the connection stability between the first support portion and the fixing disk is enhanced.

[0022] In one embodiment, the connector abuts against the second surface in a direction pointing from the second surface to the first surface. This abutment between the connector and the second surface prevents the first support portion from detaching from the shell body.

[0023] In one embodiment, a recess is formed on the second surface of the shell body, the groove of the recess facing away from the fixing plate, and one end of the connector facing away from the bottom wall of the receiving groove is disposed within the recess. This prevents the portion of the connector located on the second surface from protruding from the shell body.

[0024] In one embodiment, the shell body has a limiting hole that penetrates the first surface and the bottom wall of the recess. The fixing part further includes a limiting member, which is fixedly connected to the surface of the fixing plate opposite to the slide groove. The limiting member is disposed within the limiting hole to prevent the fixing part from rotating relative to the shell body.

[0025] In one embodiment, the shell body has a foolproof hole that penetrates the first surface and the bottom wall of the recess. The fixing part further includes a foolproof component, which is fixedly connected to the surface of the fixing plate opposite to the slide groove. The foolproof component is disposed in the foolproof hole, so that the fixing plate is positioned correctly on the first surface.

[0026] In one embodiment, the first support body includes a first hinge seat, which is one end of the first support body. The second support body includes a second hinge seat, which is one end of the second support body. The first support part further includes a rotating shaft and an elastic element. The elastic element is sleeved on the rotating shaft, which is disposed between the first hinge seat and the second hinge seat. The rotating shaft is rotatably connected to the first hinge seat and / or the second hinge seat. The elastic element is connected to both the first support body and the second support body. When the second support body is fitted against the first support body, the elastic element is elastically compressed. The elastic element releases its elastic potential energy, causing the second support body to open relative to the first support body to a preset angle. The release of elastic potential energy by the elastic element automatically makes the angle between the second support body and the first support body the preset angle, without requiring manual rotation of the second support body to achieve this angle.

[0027] In some embodiments, the elastic element is a torsion spring, which is sleeved on the rotating shaft, and its two torsion arms are respectively connected to the first support and the second support. By sleeved on the rotating shaft, the torsion spring is more securely fixed, preventing it from falling off. Furthermore, helical torsion springs offer advantages such as smooth torsion and long service life.

[0028] In one embodiment, the first support portion further includes a first magnetic element disposed on the first support body. The second support portion further includes a second magnetic element disposed on the second support body. The first and second magnetic elements magnetically attract each other, causing the second support body to adhere to the first support body. The magnetic attraction between the first and second magnetic elements prevents the second support body from opening relative to the first support body without external force.

[0029] In some embodiments, the first magnetic element is a permanent magnet and the second magnetic element is a non-permanent magnet; or, the first magnetic element is a non-permanent magnet and the second magnetic element is a permanent magnet; or, both the first magnetic element and the second magnetic element are permanent magnets.

[0030] In some embodiments, when the second support portion is attached to the first support portion, the torque of the magnetic force of the first magnetic element on the second magnetic element is greater than the torque of the elastic element on the second support body, so that the second support portion is stably attached to the first support portion.

[0031] Secondly, embodiments of this application provide a terminal component, the terminal component including a mobile terminal and the aforementioned protective case, the mobile terminal being disposed within the protective case.

[0032] In summary, the terminal component provided in this application includes a mobile terminal and a protective case. When the mobile terminal is placed vertically on an object, the slider of the protective case abuts against the first limiting wall, and the torque of the first holding force of the first limiting wall on the slider is opposite to the torque of the first supporting force of the object on the second supporting part. This prevents the bracket from rotating relative to the mobile terminal when the mobile terminal is placed vertically, and enhances the support of the bracket for the mobile terminal.

[0073] The terms "first," "second," etc., are used for descriptive purposes only and have no sequential or technical meaning, nor should they be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Directional terms used in this application, such as "up," "down," "front," "back," "left," "right," "inner," and "outer," are merely for reference to the orientation shown in the accompanying drawings. Furthermore, the references to "clockwise" and "counterclockwise" in this application are also for reference to the orientation shown in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of this application, and not to indicate the orientation of the referred device or component in a practical application scenario.

[0074] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Rotary connection" refers to a connection where the two parts can rotate relative to each other after connection. "Sliding connection" refers to a connection where the two parts can slide relative to each other after connection.

[0075] In the embodiments of this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0076] The terms "parallel" and "perpendicular" are relative to the current technological level, not absolute mathematical definitions. Slight deviations are permissible; approximations of parallelism or perpendicularity are acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, with the angle between them ranging from 0 to 5 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, with the angle between them ranging from 85 to 95 degrees.

[0077] The embodiments of this application are described below with reference to the accompanying drawings.

[0078] Please refer to Figure 1, which is a three-dimensional structural diagram of the terminal component disclosed in this application embodiment. The mobile terminal component includes a protective case 1 and a mobile terminal 2. The protective case 1 is fitted onto the peripheral side and back of the mobile terminal 2; it can also be understood that the mobile terminal 2 is housed within the protective case 1, with the display side of the mobile terminal 2 exposed above the protective case 1. The back of the mobile terminal 2 is the surface opposite to the display side. The protective case 1 and the mobile terminal 2 are detachably connected, meaning that the user can choose whether to cover the mobile terminal 2 with the protective case 1 based on actual usage scenarios or habits. The protective case 1 is used to protect and support the mobile terminal 2, which can be a mobile phone, tablet computer, e-reader, or other terminal device.

[0079] For ease of description, the length direction of the protective shell 1 shown in Figure 1 is defined as the X-axis direction, the width direction as the Y-axis direction, and the thickness direction as the Z-axis direction. The X-axis, Y-axis, and Z-axis directions are all perpendicular to each other.

[0080] Please refer to Figures 2 to 5. Figure 2 is an exploded structural diagram of the protective shell disclosed in the embodiment of this application. Figure 3 is a three-dimensional structural diagram of the protective shell disclosed in the embodiment of this application. Figure 4 is a first front view structural diagram of the protective shell disclosed in the embodiment of this application. Figure 5 is a second front view structural diagram of the protective shell disclosed in the embodiment of this application. The protective shell 1 includes a shell body 10, a shell side body (not shown), a fixing part 20, and a bracket 30. The shell side body is disposed on the peripheral side of the shell body 10 and extends in the opposite direction to the Z-axis of the shell body 10. The opposite direction to the Z-axis is opposite to the Z-axis direction. The fixing part 20 is disposed on the surface of the shell body 10 facing the Z-axis direction. The bracket 30 is disposed on the surface of the shell body 10 facing the Z-axis direction and covers the fixing part 20. The shell side body is fixedly connected to the shell body 10, the fixing part is fixedly connected to the shell body 10, and the bracket 30 is rotatably connected to the fixing part, so that the bracket 30 can rotate relative to the shell body 10.

[0081] The outer shell side is fitted onto the peripheral side of the mobile terminal 2, and the outer shell body 10 is connected to the back of the mobile terminal 2. The outer shell body 10 and the outer shell side are used to fix the mobile terminal 2. The bracket 30 is used to support the outer shell body 10, so that the protective shell 1 can support the mobile terminal 2.

[0082] It should be noted that the shell body 10 and the shell edge body can be made of transparent material or opaque material.

[0083] In this application, the length direction of the bracket 30 in Figure 4 is parallel to the Y-axis, and the length direction of the bracket 30 in Figure 5 is parallel to the X-axis. The arrow S1 in Figure 4 indicates a clockwise direction, meaning the bracket 30 can rotate clockwise. The arrow S2 in Figure 5 indicates a counter-clockwise direction, meaning the bracket 30 can rotate counter-clockwise. The bracket 30 in Figure 4 can rotate 270 degrees clockwise relative to the shell body 10, as shown in Figure 5. The bracket 30 in Figure 5 can rotate 270 degrees counter-clockwise relative to the shell body 10, as shown in Figure 4.

[0084] It should be noted that a rotation of 270 degrees is not a strictly defined mathematical figure; slight deviations are permissible. Approximate values ​​of 270 are acceptable. For example, if the rotation angle of bracket 30 ranges from 265 degrees to 275 degrees, it can be considered that the rotation angle of bracket 30 is 270 degrees.

[0085] Please refer to Figures 6 and 7. Figure 6 is a structural schematic diagram of the protective case in a vertical screen support state according to an embodiment of this application, and Figure 7 is a structural schematic diagram of the protective case in a horizontal screen support state according to an embodiment of this application. The bracket 30 includes a first support portion 310 and a second support portion 320. The first support portion 310 is disposed on the surface of the shell body 10 and covers the fixing portion 20. The second support portion 320 is disposed at one end of the first support portion 310. The first support portion 310 is rotatably connected to the fixing portion 20, and the second support portion 320 is rotatably connected to the first support portion 310. The first support portion 310 can drive the second support portion 320 to rotate relative to the shell body 10. The second support portion 320 can rotate relative to the first support portion 310, so that the second support portion 320 can fit against the surface of the first support portion 310 facing away from the shell body 10, or the second support portion 320 can open at an angle relative to the first support portion 310. When the protective case 1 is in portrait mode, the mobile terminal 2 displays the image in portrait mode; when the protective case 1 is in landscape mode, the mobile terminal 2 displays the image in portrait mode. The bracket 30 can be closed or opened. The bracket 30 in Figure 4 is closed; the bracket 30 in Figure 4 is open as shown in Figure 6. The bracket 30 in Figure 5 is closed; the bracket 30 in Figure 5 is open as shown in Figure 7. That is, the bracket 30 in Figure 6 rotates 270 degrees clockwise as shown in Figure 7, and the bracket 30 in Figure 7 rotates 270 degrees counterclockwise as shown in Figure 6. In Figures 6 and 7, when the bracket 30 is open, the second support part 320 and the case body 10 are placed on something, thus enabling the protective case 1 to support the mobile terminal 2.

[0086] It should be noted that after the second support portion 320 is opened at an angle relative to the first support portion 310, the preset angle between the second support portion 320 and the first support portion 310 can be between 60 degrees and 120 degrees. For example, 60 degrees, 71 degrees, 79 degrees, 85 degrees, 90 degrees, 100 degrees, 105 degrees, 112 degrees, 120 degrees, or other values; this application does not impose specific limitations on this. Understandably, a preset angle of 90 degrees between the second support portion 320 and the first support portion 310, with better connection stability, can prevent the second support portion 320 from rotating relative to the first support portion 310 due to the supporting force exerted by something.

[0087] Please refer to Figures 6 to 8. Figure 8 is a front view structural diagram of the shell body disclosed in an embodiment of this application. The shell body 10 includes a bottom surface 10a, a top surface 10b, a first surface 10c, a second surface 10d, a first side surface 10e, and a second side surface 10f. The bottom surface 10a and the top surface 10b are arranged opposite to each other along the X-axis, the first surface 10c and the second surface 10d are arranged opposite to each other along the Z-axis, and the first side surface 10e and the second side surface 10f are arranged opposite to each other along the Y-axis. The bottom surface 10a is connected to the first surface 10c, the second surface 10d, the first side surface 10e, and the second side surface 10f, respectively. The top surface 10b is connected to the first surface 10c, the second surface 10d, the first side surface 10e, and the second side surface 10f, respectively. The first surface 10c is connected to the bottom surface 10a, the top surface 10b, the first side surface 10e, and the second side surface 10f, respectively. The second surface 10d is connected to the bottom surface 10a, the top surface 10b, the first side surface 10e, and the second side surface 10f, respectively.

[0088] The shell side body surrounds the bottom surface 10a, top surface 10b, first side surface 10e, and second side surface 10f. The shell side body extends in the direction facing the second surface 10d, and the bracket 30 is disposed on the first surface 10c. When the protective shell 1 covers the mobile terminal 2, the second surface 10d is in contact with the back of the mobile terminal 2, and the inner side surface of the shell side body is in contact with the peripheral side surface of the mobile terminal 2.

[0089] In this application, the shell body 10 is a plate-like structure. The length direction of the shell body 10 is parallel to the X-axis, the width direction is parallel to the Y-axis, and the thickness direction is parallel to the Z-axis. The length and width of the shell body 10 are determined according to the size of the mobile terminal 2. While ensuring the structural strength of the protective shell 1, the thickness of the shell body 10 can be appropriately reduced to avoid excessively increasing the thickness of the terminal components. The shell side body is a frame structure. While ensuring the structural strength of the protective shell 1, the wall thickness of the shell side body can also be appropriately reduced to avoid excessively increasing the length and width of the terminal components.

[0090] Please refer to Figures 8 to 10. Figure 9 is an enlarged schematic diagram of structure I in the shell body shown in Figure 8, and Figure 10 is a cross-sectional schematic diagram of the shell body shown in Figure 9 along the II-II direction. The shell body 10 has a light-transmitting hole 12, a first mounting hole 13, a limiting hole 14, a foolproof hole 15, and a recess 16. As shown in Figure 8, the light-transmitting hole 12 penetrates the first surface 10c and the second surface 10d. The light-transmitting hole 12 is a cylindrical through hole, and it coincides with the camera of the mobile terminal 2, allowing ambient light to pass through the light-transmitting hole 12 to the camera. The number of light-transmitting holes 12 can be one or more, and their number can be determined according to the number of cameras of the mobile terminal 2. This application does not impose specific limitations on this.

[0091] In this application, please refer to Figures 8 and 9. The first mounting hole 13 penetrates the first surface 10c and the second surface 10d. The light-transmitting hole 12 is closer to the top surface 10b than the first mounting hole 13, and the first mounting hole 13 is closer to the bottom surface 10a than the light-transmitting hole 12. That is, the bottom surface 10a, the first mounting hole 13, the light-transmitting hole 12, and the top surface 10b are arranged sequentially along the X-axis. The first mounting hole 13 is a cylindrical through hole, and there is only one of them.

[0092] Referring to Figure 9, the limiting hole 14 penetrates the first surface 10c and the second surface 10d. The limiting hole 14 is located close to the first mounting hole 13 and is spaced apart from the first mounting hole 13. There are four limiting holes 14, arranged around the centerline of the first mounting hole 13, which is parallel to the Z-axis. Two limiting holes 14 are spaced apart along the X-axis, and the other two are spaced apart along the Y-axis. In other embodiments, the number of limiting holes 14 can be one, two, three, or more than four. This application does not impose a specific limitation on the number of limiting holes 14.

[0093] Referring to Figure 9, the anti-mistake hole 15 penetrates the first surface 10c and the second surface 10d. The anti-mistake hole 15 is located near the first mounting hole 13 and is spaced apart from both the first mounting hole 13 and the limiting hole 14. The anti-mistake hole 15 is a cylindrical through hole, and there are two of them. The two anti-mistake holes 15 are spaced apart along the Y-axis, and the center point between the two anti-mistake holes 15 is not on the center line of the first mounting hole 13. The two anti-mistake holes 15 are located near the two limiting holes 14 located along the Y-axis. In other embodiments, the number of anti-mistake holes 15 can be three, four, or other numbers, as long as the center point between the multiple anti-mistake holes 15 is not on the center line of the first mounting hole 13.

[0094] Please refer to Figure 10. The recess 16 is formed on the second surface 10d, meaning that the recess 16 does not penetrate the shell body 10, and the opening of the recess 16 faces away from the first surface 10c. The first mounting hole 13 penetrates the first surface 10c and the bottom wall of the recess 16, the limiting hole 14 penetrates the first surface 10c and the bottom wall of the recess 16, and the foolproof hole 15 penetrates the first surface 10c and the bottom wall of the recess 16. That is, the first mounting hole 13, the limiting hole 14, and the foolproof hole 15 are all connected to the recess 16. "Connected" means that they are connected and communicate with each other. The bottom wall of the recess 16 is also the first surface 10c. The recess 16 is a cylindrical stepped groove, and the center line of the recess 16 is aligned with the center line of the first mounting hole 13. That is, the first mounting hole 13 is located in the central region of the recess 16.

[0095] It should be noted that the shell body 10 can be defined as having a mounting area 19, with the recess 16 located exactly within this mounting area 19. The first mounting hole 13, the limiting hole 14, and the anti-fooling hole 15 are also located within this mounting area 19. The recess 16 can be considered as the second surface 10d located within the mounting area 19, which is concave towards the Z-axis. Moreover, the first surface 10c located within the mounting area 19 is convex towards the Z-axis, thus preventing the presence of the recess 16 within the mounting area 19 from reducing the thickness of the shell body 10 within the mounting area 19, thereby preventing a reduction in the structural strength of the shell body 10.

[0096] Please refer to Figures 11 to 16. Figure 11 is a three-dimensional structural diagram of the fixing part shown in Figure 2 from one perspective; Figure 12 is a three-dimensional structural diagram of the fixing part shown in Figure 11 from another perspective; Figure 13 is a top view of the fixing part shown in Figure 11; Figure 14 is a bottom view of the fixing part shown in Figure 11; Figure 15 is a side view of the fixing part shown in Figure 11; and Figure 16 is a structural diagram of the fixing part shown in Figure 11 after disassembly. The fixing part 20 includes a fixing plate 21, a flexible member 22, a limiting member 23, a foolproof member 25, and a supporting member 26. The flexible member 22 is detachably connected to the fixing plate 21, and the limiting member 23, the foolproof member 25, and the supporting member 26 are all fixedly connected to the fixing plate 21. The fixing plate 21 includes a first mounting surface 211 and a second mounting surface 212 arranged opposite to each other.

[0097] Please refer to Figures 16 and 17. Figure 17 is a front view of the fixing plate of the fixing part shown in Figure 11. The fixing plate 21 is disc-shaped and has a sliding groove 21a, a mounting groove 21b, a second mounting hole 21c, and a hollow portion 21d. Specifically, the second mounting hole 21c penetrates the first mounting surface 211 and the second mounting surface 212 of the fixing plate 21. The second mounting hole 21c is a cylindrical through hole, and its center line is aligned with the center line of the fixing plate 21. The center line of the fixing plate 21 is parallel to the thickness direction of the shell body. The mounting groove 21b is formed on the first mounting surface 211 of the fixing plate 21 and is spaced apart from the second mounting hole 21c. The mounting groove 21b is an annular groove that extends around the center line of the second mounting hole 21c, and its center line is aligned with the center line of the second mounting hole 21c.

[0098] A groove 21a is formed on the first assembly surface 211 of the fixed plate 21, and is spaced apart from the second assembly hole 21c and the mounting groove 21b. The groove 21a is an arc-shaped groove extending around the centerline of the second assembly hole 21c, with the centerline of the groove 21a aligned with the centerline of the second assembly hole 21c. The radius of the groove 21a is larger than the radius of the mounting groove 21b, meaning the mounting groove 21b is closer to the second assembly hole 21c than the groove 21a. The sidewall of the groove is arc-shaped, with an arc angle greater than 270 degrees and less than 360 degrees. Therefore, the extension path of the groove 21a can be considered as an arc with an arc angle greater than 270 degrees and less than 360 degrees. The slide groove 21a includes a first limiting wall a1 and a second limiting wall a2. The first limiting wall a1 and the second limiting wall a2 are two walls in the extension direction of the slide groove 21a. That is, the slide groove 21a extends from the first limiting wall a1 to the second limiting wall a2. Moreover, from the moment the slider 312 abuts against the first limiting wall a1 to the moment the slider 312 abuts against the second limiting wall a2, the slider 312 needs to rotate 270 degrees within the slide groove 21a.

[0099] Please refer to Figures 11, 12, 17, and 18. Figure 18 is a cross-sectional view of the fixing part shown in Figure 15 along the III-III direction. The hollow part 21d is formed inside the fixing plate 21. The first limiting wall a1 has a first opening a11, and the second limiting wall a2 has a second opening a21. The hollow part 21d communicates with both the first opening a11 and the second opening a21, allowing it to communicate with the sliding groove 21a. The first limiting wall a1 and the second limiting wall a2 expose the hollow part 21d. The extension path of the hollow part 21d can be considered as an arc. The diameter of the arc corresponding to the hollow part 21d is equal to the diameter of the arc corresponding to the sliding groove 21a, and the sum of the arc degree of the arc corresponding to the hollow part 21d and the arc degree of the corresponding arc degree of the sliding groove 21a is 360 degrees. That is, the hollow part 21d and the sliding groove 21a together form a circular notch.

[0100] For example, referring to Figures 11 and 18, the cutout portion 21d includes a first cutout sub-portion d1, a second cutout sub-portion d2, and a third cutout sub-portion d3. The first cutout sub-portion d1 is disposed near the first limiting wall a1 and communicates with the first opening a11, so that the slide groove 21a communicates with the first cutout sub-portion d1. The first cutout sub-portion d1 penetrates the first mounting surface 211 and the second mounting surface 212 of the fixed disk 21. In other embodiments, the first cutout sub-portion d1 may not penetrate the first mounting surface 211 and the second mounting surface 212 of the fixed disk 21, or it may penetrate either the first mounting surface 211 or the second mounting surface 212 of the fixed disk 21. This application does not impose specific limitations on this.

[0101] Please refer to Figures 12 and 18. The second hollowed-out sub-part d2 is disposed near the second limiting wall a2. The second hollowed-out sub-part d2 is spaced apart from the first hollowed-out sub-part d1 and communicates with the second opening a21, so that the sliding groove 21a communicates with the second hollowed-out sub-part d2. The second hollowed-out sub-part d2 penetrates the first mounting surface 211 and the second mounting surface 212 of the fixing plate 21. In other embodiments, the second hollowed-out sub-part d2 may not penetrate the first mounting surface 211 and the second mounting surface 212 of the fixing plate 21, or it may penetrate either the first mounting surface 211 or the second mounting surface 212 of the fixing plate 21. This application does not impose specific limitations on this.

[0102] As shown in Figure 18, the third hollow sub-part d3 is disposed between the first hollow sub-part d1 and the second hollow sub-part d2, and the third hollow sub-part d3 is connected to both the second hollow sub-part d2 and the third hollow sub-part d3. The third hollow sub-part d3 does not penetrate the first mounting surface 211 and the second mounting surface 212 of the fixing plate 21.

[0103] Please refer to Figures 11, 15 and 16. The flexible member 22 is annular and is disposed in the mounting groove 21b. The flexible member 22 is detachably connected to the fixed plate 21. The surface of the flexible member 22 facing away from the bottom of the mounting groove 21b extends out of the first mounting surface 211, that is, the surface of the flexible member 22 facing away from the bottom of the mounting groove 21b extends out of the groove of the mounting groove 21b. In other words, the thickness of the flexible member 22 is greater than the depth of the mounting groove 21b. The mounting groove 21b is used to prevent the flexible member 22 from detaching from the fixed plate 21.

[0104] It should be noted that the flexible component 22 can be made of elastic material. The flexible component 22 will deform under the action of external force, and after the external force is removed, the flexible component 22 will return to its original shape.

[0105] Please refer to Figures 11, 14, and 15. Both the limiting member 23 and the foolproof member 25 protrude from the second mounting surface 212 of the fixed plate 21, and both the limiting member 23 and the foolproof member 25 are fixedly connected to the fixed plate 21. Furthermore, the fixed plate 21 and the limiting member 23 can be integrally formed, and the fixed plate 21 and the foolproof member 25 can be integrally formed.

[0106] For example, as shown in FIG14, there are four limiting members 23, which are arranged around the center line of the second mounting hole 21c. Two limiting members 23 are spaced apart along the X-axis, and the other two are spaced apart along the Y-axis. In other embodiments, the number of limiting members 23 may be one, two, three, or more than four; this application does not impose a specific limitation on the number of limiting members 23.

[0107] The anti-misalignment element 25 is cylindrical, and there are two of them. The center point between the two anti-misalignment elements 25 is not on the center line of the second mounting hole 21c. The two anti-misalignment elements 25 are respectively close to the two limiting elements 23 arranged along the Y-axis direction. In other embodiments, the number of anti-misalignment elements 25 can be three, four, or other more. This application does not impose a specific limitation on this, as long as the center point between the multiple anti-misalignment elements 25 is not on the center line of the second mounting hole 21c.

[0108] Please refer to Figures 11, 12, and 18. The abutment 26 is disposed within the hollow portion 21d. The abutment 26 includes a first abutment surface 26a and a second abutment surface 26b disposed opposite to each other. As shown in Figures 11 and 18, the first abutment surface 26a is located at the first opening a11, and the first limiting wall a1 is flush with the first abutment surface 26a. As shown in Figures 12 and 18, the second abutment surface 26b is located at the second opening a21, and the second limiting wall a2 is flush with the second abutment surface 26b.

[0109] Please refer to Figures 19 and 20. Figure 19 is a three-dimensional structural diagram of the abutment member in Figure 16 from one perspective, and Figure 20 is a three-dimensional structural diagram of the abutment member in Figure 16 from another perspective. The abutment member 26 includes a first abutment sub-member 261, a second abutment sub-member 262, and a third abutment sub-member 263. The first abutment surface 26a is one of the peripheral side surfaces of the first abutment sub-member 261, and the second abutment surface 26b is one of the peripheral side surfaces of the second abutment sub-member 262. The opposite ends of the third abutment sub-member 263 are respectively connected to the first abutment sub-member 261 and the second abutment sub-member 262, and the third abutment sub-member 263 is connected to the peripheral side surfaces of the first abutment sub-member 261 except for the first abutment surface 26a, and the third abutment sub-member 263 is connected to the peripheral side surfaces of the second abutment sub-member 262 except for the second abutment surface 26b. The third abutment component 263 is used to fix the first abutment component 261 and the second abutment component 262 to the fixing plate 21.

[0110] Referring to Figure 18, the first abutment member 261 is disposed within the first hollowed-out sub-part d1, the second abutment member 262 is disposed within the second hollowed-out sub-part d2, and the third abutment member 263 is disposed within the third hollowed-out sub-part d3. As shown in Figure 13, the first abutment member 261 exposes the first mounting surface 211, and the surface of the first abutment member 261 exposed above the first mounting surface 211 is flush with the first mounting surface 211. The second abutment member 262 exposes the first mounting surface 211, and the surface of the second abutment member 262 exposed above the first mounting surface 211 is flush with the first mounting surface 211. As shown in Figure 14, the first abutment member 261 exposes the second mounting surface 212, and the surface of the first abutment member 261 exposed above the second mounting surface 212 is flush with the second mounting surface 212. The second abutment member 262 exposes the second mounting surface 212, and the surface of the second abutment member 262 exposed above the second mounting surface 212 is flush with the second mounting surface 212. In other embodiments, the first abutment member 261 may not expose the first mounting surface 211 and / or the second mounting surface 212, and the second abutment member 262 may not expose the first mounting surface 211 and / or the second mounting surface 212. This application does not impose specific limitations on this. In this application, the third abutment members 263 do not expose the first mounting surface 211 and the second mounting surface 212.

[0111] It should be noted that, as shown in Figures 18 to 20, the surface of the third supporting member 263 is also provided with multiple protrusions. Correspondingly, the inner wall of the third hollowed-out part d3 is provided with multiple recesses. The position of the recess corresponds to the position of the protrusion, the shape of the recess corresponds to the shape of the protrusion, and the size of the recess corresponds to the size of the protrusion. One protrusion is disposed within one recess. It can be understood that the protrusion being disposed within the recess can enhance the connection between the third supporting member 263 and the fixing plate 21, thereby enhancing the connection between the supporting member 26 and the fixing plate 21.

[0112] It should also be noted that the material of the supporting member 26 includes metal, and more specifically, the material of the supporting member 26 includes aluminum alloy. The first supporting sub-member 261, the second supporting sub-member 262, and the third supporting sub-member 263 are integrally formed. The material of the fixing plate 21 includes plastic, and the fixing plate 21 is formed by injection molding, thereby placing the supporting member 26 inside the fixing plate 21. That is, the supporting member 26 is formed first, and then the supporting member 26 is placed into the mold for forming the fixing plate 21, and the fixing plate 21 is formed in the mold by injection molding.

[0113] Please refer to Figure 21, which is a structural schematic diagram from one perspective of the fixing part being assembled to the shell body. The fixing plate 21 is disposed on the first surface 10c, that is, the second mounting surface 212 of the fixing plate 21 is connected to the first surface 10c of the shell body 10. Both the first mounting surface 211 of the fixing plate 21 and the first surface 10c of the shell body 10 face the Z-axis direction. The groove opening of the sliding groove 21a and the groove opening of the mounting groove 21b both face away from the second surface 10d, that is, the orientation of the groove opening of the sliding groove 21a is the same as the orientation of the first surface 10c, and the orientation of the groove opening of the mounting groove 21b is the same as the orientation of the first surface 10c.

[0114] Please refer to Figure 22, which is a structural schematic diagram from another perspective of the fixing part being assembled to the shell body. A limiting member 23 is disposed in a limiting hole 14, and a foolproof member 25 is disposed in a foolproof hole 15. The end of the limiting member 23 facing away from the fixing plate 21 and the end of the foolproof member 25 facing away from the fixing plate 21 are both located in the recess 16. The center line of the second assembly hole 21c coincides with the center line of the first assembly hole 13.

[0115] Understandably, the limiting member 23 has two opposite ends, with one end being larger than the other. The larger end of the limiting member 23 is connected to the fixing plate 21, and the smaller end is the end of the limiting member 23 facing away from the fixing plate 21. The smaller end of the limiting member 23 facilitates alignment between the limiting member 23 and the limiting hole 14, making it easier for the limiting member 23 to be assembled into the limiting hole 14. The end of the foolproof member 25 facing away from the fixing plate 21 is a hemisphere or semi-ellipsoid. The smaller size of the end of the foolproof member 25 facing away from the fixing plate 21 facilitates alignment between the foolproof member 25 and the foolproof hole 15, making it easier for the foolproof member 25 to be assembled into the foolproof hole 15.

[0116] It can also be understood that by assembling the anti-foolproof part 25 into the anti-foolproof hole 15, the assembly relationship between the fixing part 20 and the shell body 10 is unique. That is, after the fixing part 20 is assembled into the shell body 10, there is only one orientation of the fixing part 20 relative to the shell body 10, so that the fixing part 20 is set in the shell body 10 in the correct orientation.

[0117] It should be noted that the limiting member 23, when assembled into the limiting hole 14, can restrict the rotation of the fixing part 20 relative to the shell body 10. Similarly, the anti-misalignment member 25, when assembled into the anti-misalignment hole 15, can also restrict the rotation of the fixing part 20 relative to the shell body 10. However, the fixing part 20 can detach from the shell body 10 in the direction (Z-axis direction) pointing from the second surface 10d to the first surface 10c. In this application, both the limiting member 23 and the anti-misalignment member 25 are made of thermoplastic materials. After the limiting member 23 is assembled into the limiting hole 14 and the anti-misalignment member 25 is assembled into the anti-misalignment hole 15, the limiting member 23 and the anti-misalignment member 25 are deformed through a thermoplastic process. The deformed limiting member 23 is fixed to the shell body 10, and the deformed anti-misalignment member 25 is fixed to the shell body 10. The fixing part 20 cannot detach from the shell body 10 in the direction pointing from the second surface 10d to the first surface 10c.

[0118] Please refer to Figures 23 to 27. Figure 23 is a top view of the first support portion shown in Figure 2; Figure 24 is a bottom view of the first support portion shown in Figure 23; Figure 25 is a front view of the first support portion shown in Figure 23; Figure 26 is a structural diagram from one perspective after disassembling the first support portion shown in Figure 25; and Figure 27 is a structural diagram from another perspective after disassembling the first support portion shown in Figure 25. In this application, the first support portion 310 includes a first support body 311, a slider 312, a first magnetic element 313, a rotating shaft 314, an elastic element 315, a damping element 316, a connecting element 317, and a scratch-resistant element 318. The slider 312, the first magnetic component 313, the rotating shaft 314, the elastic component 315, the damping component 316, the connecting component 317, and the anti-scratch component 318 are all disposed on the first support body 311. The first magnetic component 313, the rotating shaft 314, the elastic component 315, the damping component 316, the connecting component 317, and the anti-scratch component 318 are respectively spaced apart from the slider 312.

[0119] Since the first support portion 310 can rotate relative to the shell body 10, only the Z-axis direction is shown in Figures 23 to 25. The first support portion 310 is described below using the length direction, width direction, and thickness direction of the first support body 311. The thickness direction of the first support body 311 is parallel to the Z-axis direction, and the length direction, width direction, and thickness direction of the first support body 311 are perpendicular to each other.

[0120] Specifically, referring to Figures 23 to 25, the first support 311 includes a first contact surface 3111 and a second contact surface 3112 arranged opposite to each other along the thickness direction of the first support 311. As shown in Figures 23 and 25, the first contact surface 3111 includes a first contact sub-surface 3111a, a second contact sub-surface 3111b, and a third contact sub-surface 3111c. The first contact sub-surface 3111a, the third contact surface 3111c, and the third contact surface 3111c are arranged sequentially along the length direction of the first support 311, and the first contact sub-surface 3111a, the second contact surface 3111b, and the third contact surface 3111c are all parallel to each other.

[0121] The first contact surface 3111a and the second contact surface 3111b have the same height in the thickness direction of the first support 311. The third contact surface 3111c has a greater height in the thickness direction of the first support 311 than the first contact surface 3111a, and a greater height in the thickness direction of the first support 311 than the second contact surface 3111b. In other words, the thickness of the first support 311 at the first contact surface 3111a is the same as the thickness at the second contact surface 3111b, and the thickness of the first support 311 at the third contact surface 3111c is greater than both the thickness at the first contact surface 3111a and the thickness at the second contact surface 3111b.

[0122] Please refer to Figure 24. The second contact surface 3112 of the first support 311 has a receiving groove 311c. There is one receiving groove 311c, which is a cylindrical groove.

[0123] It should be noted that the orthographic projection of the receiving groove 311c in the thickness direction of the first support 311 coincides with the orthographic projection of the third contact surface 3111c in the thickness direction of the first support 311. This can be understood as follows: because the receiving groove 311c is required, the thickness of the first support 311 at the third contact surface 3111c is set to be greater than the thickness of the first support 311 at the first contact surface 3111a and also greater than the thickness of the first support 311 at the second contact surface 3111b, thus preventing the opening of the receiving groove 311c from reducing the structural strength of the first support 311.

[0124] Please refer to Figure 28, which is an enlarged schematic diagram of structure IV in the first support shown in Figure 24. In this application, the damping element 316 is disposed within the receiving groove 311c, and the damping element 316 is fixedly connected to the side wall of the receiving groove 311c. Specifically, the damping element 316 is fixed to the side wall of the receiving groove 311c through an interference fit or by bonding. Specifically, the damping element 316 is an open ring, comprising a first damping body 3161, a second damping body 3162, a third damping body 3163, a fourth damping body 3164, and a fifth damping body 3165. The first damping body 3161 and the fourth damping body 3164 are arranged opposite to each other and spaced apart along the width direction of the first support body 311. The first damping body 3161 and the fifth damping body 3165 are arranged opposite to each other and spaced apart along the width direction of the first support body 311. The second damping body 3162 and the third damping body 3163 are arranged spaced apart along the length direction of the first support body 311. The opposite ends of the second damping body 3162 are respectively connected to one end of the first damping body 3161 and one end of the fourth damping body 3164. The opposite ends of the third damping body 3163 are respectively connected to the other end of the first damping body 3161 and one end of the fifth damping body 3165. The end of the fourth damping body 3164 facing away from the second damping body 3162 is spaced apart from the end of the fifth damping body 3165 facing away from the third damping body 3163. That is, the fifth damping body 3165, the third damping body 3163, the first damping body 3161, the second damping body 3162, and the fourth damping body 3164 are connected sequentially in a clockwise direction. The gap between the fourth damping body 3164 and the fifth damping body 3165 is also the unclosed part of the damping element 316.

[0125] The first damping body 3161, the second damping body 3162, the third damping body 3163, the fourth damping body 3164, and the fifth damping body 3165 are all arc-shaped segments. The radius of the outer arc surface of the first damping body 3161 is equal to the radius of the receiving groove 311c, so that the outer arc surface of the first damping body 3161 connects to the side wall of the receiving groove 311c. The radius of the outer arc surface of the fourth damping body 3164 is equal to the radius of the receiving groove 311c, so that the outer arc surface of the fourth damping body 3164 connects to the side wall of the receiving groove 311c. The radius of the outer arc surface of the fifth damping body 3165 is equal to the radius of the receiving groove 311c, so that the outer arc surface of the fifth damping body 3165 connects to the side wall of the receiving groove 311c. The radius of the outer arc surface of the second damping body 3162 is smaller than the radius of the receiving groove 311c, resulting in a gap between the outer arc surface of the second damping body 3162 and the receiving groove 311c. The radius of the outer arc surface of the third damping body 3163 is smaller than the radius of the receiving groove 311c, resulting in a gap between the outer arc surface of the third damping body 3163 and the receiving groove 311c.

[0126] It should be noted that the damping element 316 is fixedly connected to the side wall of the receiving groove 311c via the first damping body 3161, the fourth damping body 3164, and the fifth damping body 3165, thereby fixing the damping element 316 to the side wall of the receiving groove 311c. Furthermore, the relatively arranged first damping body 3161 and fourth damping body 3164, as well as the relatively arranged first damping body 3161 and fifth damping body 3165, make the connection between the damping element 316 and the side wall of the receiving groove 311c more stable.

[0127] It should also be noted that the side wall of the receiving groove 311c is provided with an abutment 319, which is located between the fourth damping body 3164 and the fifth damping body 3165, and is fixedly connected to the side wall of the receiving groove 311c. The abutment 319 can enhance the fixation between the side wall of the receiving groove 311c and the damping member 316, preventing the damping member 316 from falling off the side wall of the receiving groove 311c. The abutment 319 is integrally formed with the first support body 311.

[0128] The slider 312 is disposed on the bottom wall of the receiving groove 311c, and the slider 312 is fixedly connected to the bottom wall of the receiving groove 311c. The slider 312 is an arc block, that is, the extension path of the slider 312 is an arc, and the arc degree of the arc is less than 90 degrees. The slider 312 is integrally formed with the first support body 311.

[0129] Please refer to Figures 26 to 28. The connector 317 is disposed within the receiving groove 311c. Specifically, the connector 317 includes a fixed shaft 3171 and a bushing 3172. The fixed shaft 3171 is fixedly connected to the bottom wall of the receiving groove 311c, extending towards the opening of the receiving groove 311c, with one end of the fixed shaft 3171 facing away from the bottom wall of the receiving groove 311c extending beyond the opening. The fixed shaft 3171 is a stepped shaft, comprising a first fixed sub-shaft 3171a and a second fixed sub-shaft 3171b. The diameter of the first fixed sub-shaft 3171a is larger than the diameter of the second fixed sub-shaft 3171b. The first fixed sub-shaft 3171a is fixedly connected to the bottom wall of the receiving groove 311c, and the second fixed sub-shaft 3171b is fixedly connected to the end of the first fixed sub-shaft 3171a facing away from the bottom wall of the receiving groove 311c. The fixed shaft 3171 is integrally formed with the first support body 311.

[0130] The bushing 3172 includes a first sleeve body 3172a and a second sleeve body 3172b. The second sleeve body 3172b is disposed at one end of the first sleeve body 3172a and extends towards the periphery of the first sleeve body 3172a. That is, the center line of the first sleeve body 3172a is aligned with the center line of the second sleeve body 3172b. The inner diameter of the first sleeve body 3172a is equal to the inner diameter of the second sleeve body 3172b, and the outer diameter of the second sleeve body 3172b is larger than the outer diameter of the first sleeve body 3172a. The bushing 3172 is sleeved on the second fixed sub-shaft 3171b, and the first sleeve body 3172a is closer to the first fixed sub-shaft 3171a than the second sleeve body 3172b. The fixed shaft 3171 and the bushing 3172 can be fixed to the fixed shaft 3171 by means of threaded connection, interference fit, bonding, key connection, etc.

[0131] Please refer to Figures 24 and 27. The second contact surface 3112 of the first support 311 has a first fixing groove 311d and a second fixing groove 311e. The orthographic projection of the first fixing groove 311d in the thickness direction of the first support 311 coincides with the orthographic projection of the first contact surface 3111a in the thickness direction of the first support 311. The orthographic projection of the second fixing groove 311e in the thickness direction of the first support 311 coincides with the orthographic projection of the second contact surface 3111b in the thickness direction of the first support 311.

[0132] In this application, there is one first magnetic element 313 and two anti-scratch elements 318. For ease of distinction, one anti-scratch element 318 is defined as the first anti-scratch element 318a, and the other anti-scratch element is defined as the second anti-scratch element 318b. As shown in Figure 27, the first anti-scratch element 318a is disposed within the first fixing groove 311d, and the surface of the first anti-scratch element 318a facing away from the bottom wall of the first fixing groove 311d extends out to the second contact surface 3112. That is, part of the first anti-scratch element 318a is disposed within the first fixing groove 311d, and the other part of the first anti-scratch element 318a protrudes from the second contact surface 3112. The first magnetic element 313 is disposed on the bottom wall of the second fixing groove 311e, and the thickness of the first magnetic element 313 is less than the depth of the second fixing groove 311e. The second anti-scratch member 318b is disposed within the second fixing groove 311e, and is connected to the surface of the first magnetic member 313 facing away from the bottom wall of the second fixing groove 311e. The surface of the second anti-scratch member 318b facing away from the first magnetic member 313 extends beyond the second contact surface 3112; that is, part of the second anti-scratch member 318b is disposed within the second fixing groove 311e, while another part protrudes from the second contact surface 3112. The thickness of the first anti-scratch member 318a protruding from the second contact surface 3112 is the same as the thickness of the second anti-scratch member 318b protruding from the second contact surface 3112. The anti-scratch member 318b can be made of an elastic material, giving it a certain degree of deformation capability.

[0133] Specifically, please refer to Figure 29, which is a schematic diagram of the structure of the rotating shaft assembled to the first support body. The first support body 311 includes a first hinge seat 311a, which is one end of the first support body 311 along its length and is close to the second contact surface 3111b. That is, the first contact surface 3111a, the third contact surface 3111c, the second contact surface 3111b, and the first hinge seat 311a are arranged sequentially along the length of the first support body 311. The first hinge seat 311a has a first mounting hole that extends through the first hinge seat 311a along the width of the first support body 311. In this application, there are two first hinge seats 311a, which are spaced apart along the width of the first support body 311. In other embodiments, the number of first hinge seats 311a may be greater than two.

[0134] A rotating shaft 314 is disposed within the first mounting holes of two first hinge seats 311a, with its opposite ends extending out of the first hinge seats 311a. An elastic element 315 is connected to the first support body 311. In this application, the elastic element 315 is a torsion spring, disposed between the two first hinge seats 311a, sleeved on the rotating shaft 314, and one torsion arm of the torsion spring is connected to the first support body 311. In other embodiments, the elastic element 315 may also be a leaf spring, a coil spring, etc., and this application does not impose specific limitations on this.

[0135] Please refer to Figures 30 and 31. Figure 30 is a structural schematic diagram of the first support member and the fixing part after assembly, and Figure 31 is a cross-sectional schematic diagram of the first support member and the fixing part shown in Figure 30 along the VV direction. For ease of illustration, the shell body 10 is omitted in Figure 30, but is shown in Figure 31. In this application, the first support 311 is disposed on the first surface 10c, and the first support 311 covers the fixing plate 21. The opening of the receiving groove 311c faces the first surface 10c, and the fixing plate 21 is located in the receiving groove 311c. The openings of the sliding groove 21a and the mounting groove 21b of the fixing plate 21 both face the bottom wall of the receiving groove 311c, and the flexible member 22 is connected to the bottom wall of the receiving groove 311c.

[0136] Understandably, the first support 311 has a receiving groove 311c for accommodating the fixing plate 21, so that the first support 311 can protect the fixing plate 21 and reduce the overall thickness of the fixing part 20 and the bracket 30.

[0137] The centerline of the first mounting hole 13 is aligned with the centerline of the second mounting hole 21c, and the first mounting hole 13 and the second mounting hole 21c are connected. A connecting member 317 is disposed within the first mounting hole 13, the second mounting hole 21c, and the recess 16, and the connecting member 317 is clearance-fitted with the peripheral walls of the first mounting hole 13, the second mounting hole 21c, and the recess 16, allowing the connecting member 317 to rotate relative to the fixed disk 21 and the housing body 10, thereby allowing the first support portion 310 and the second support portion 320 to rotate relative to the fixed disk 21. Specifically, the first fixed sub-shaft 3171a is disposed within the second mounting hole 21c, and the second fixed sub-shaft 3171b is disposed within the second mounting hole 21c, the first mounting hole 13, and the recess 16. A bushing 3172 is disposed within the second mounting hole 21c and the recess 16. A first sleeve body 3172a is disposed within the first mounting hole 13, and the second sleeve body 3172b is disposed within the recess 16. The connector 317 abuts against the second surface 10d in the direction from the second surface 10d to the first surface 10c, that is, the second sleeve 3172b abuts against the second surface 10d in the direction from the second surface 10d to the first surface 10c. The bottom of the recess 16 is also part of the second surface 10d.

[0138] Understandably, the connection stability between the first support portion 310 and the fixing portion 20 is enhanced by the connector 317 being disposed within the first mounting hole 13 and the second mounting hole 21c. The connector 317 abuts against the second surface 10d, preventing the first support portion 310 from detaching from the shell body 10. Furthermore, the end of the connector 317 facing away from the bottom wall of the receiving groove 311c is disposed within the recess 16, preventing the portion of the connector 317 located on the second surface 10d from protruding from the shell body 10.

[0139] It should be noted that during the assembly of the first support 311 to the shell body 10, the fixed shaft 3171 and the bushing 3172 are separate. First, the fixed shaft 3171 is assembled from the first surface 10c into the first mounting hole 13, the second mounting hole 21c and the recess 16, and then the bushing 3172 is assembled from the second surface 10d into the recess 16 and the first mounting hole 13.

[0140] It should be noted that the flexible member 22 is fixedly connected to the fixed disk 21, and the flexible member 22 is slidably connected to the bottom wall of the receiving groove 311c, meaning that the first support body 311 can rotate relative to the flexible member 22 and the fixed disk 21. Alternatively, the flexible member 22 is fixedly connected to the bottom wall of the receiving groove 311c, and the flexible member 22 is slidably connected to the fixed disk 21, meaning that the first support body 311 and the flexible member 22 can rotate relative to the fixed disk 21. The flexible member 22 is used to increase the frictional force that needs to be overcome when the first support body 311 rotates relative to the fixed disk 21, preventing small external forces from causing the first support part 310 and the second support part 320 to rotate.

[0141] Understandably, the anti-scratch member 318 protrudes from the first support body 311 and contacts the first surface 10c, allowing it to slide relative to the shell body 10. The anti-scratch member 318 serves to space the first support body 311 from the shell body 10, preventing the first support body 311 from directly contacting the first surface 10c. Direct contact between the first support body 311 and the first surface 10c would increase the rotational friction of the first support portion 310, potentially causing scratches on either the first support body 311 or the shell body 10 during rotation. Therefore, when the first support portion 310 rotates relative to the shell body 10, the anti-scratch member 318 prevents the first support portion 310 from scratching the shell body 10 or the shell body 10 from scratching the first support portion 310.

[0142] In this application, the damping element 316 is located on the outer periphery of the fixed disk 21. The damping element 316 elastically abuts against the fixed disk 21 and is capable of rotating around the outer periphery of the fixed disk 21. Specifically, the inner arc surface of the first damping body 3161 is spaced from the outer periphery of the fixed disk 21, the inner arc surface of the fourth damping body 3164 is spaced from the outer periphery of the fixed disk 21, and the inner arc surface of the fifth damping body 3165 is spaced from the outer periphery of the fixed disk 21. The inner arc surface of the second damping body 3162 elastically abuts against the outer periphery of the fixed disk 21, and the inner arc surface of the third damping body 3163 elastically abuts against the outer periphery of the fixed disk 21. By elastically abutting against the fixed disk 21 with the damping element 316, rotation of the first support portion 310 and the second support portion 320 due to minor external forces can be avoided.

[0143] It should be noted that the contact area or the abutment force between the damping element 316 and the fixed disk 21 can be adjusted to regulate the frictional force that the damping element 316 needs to overcome to rotate around the fixed disk 21. The fourth damping body 3164 and the fifth damping body 3165 are spaced apart, giving the damping element 316 a certain deformation capacity, allowing it to exert a certain clamping force on the fixed disk 21 without being too large to prevent the fixed disk 21 from rotating relative to the damping element 316. Furthermore, the spacing between the second damping body 3162 and the third damping body 3163 and the sidewall of the receiving groove 311c allows for a certain deformation space, enabling the damping element 316 to elastically abut against the fixed disk 21.

[0144] It should be noted that the function of both the flexible element 22 and the damping element 316 is to prevent the first support portion 310 and the second support portion 320 from rotating due to minor external forces. In this application, both the flexible element 22 and the damping element 316 are provided. In other embodiments, only one of the flexible element 22 and the damping element 316 may be provided.

[0145] Please refer to Figures 32 and 33. Figure 32 is a schematic diagram of the slider and groove structure when the protective shell is in the vertical screen support state, and Figure 33 is a schematic diagram of the slider and groove structure when the protective shell is in the horizontal screen support state. The slider 312 is disposed within the groove 21a and is slidably connected to it. The slider 312 can slide within the groove 21a, allowing the support 30 to rotate relative to the shell body 10. The radius corresponding to the slider 312 is equal to the radius corresponding to the groove 21a. The sliding angle of the slider 312 within the groove 21a is 270 degrees. That is, when the slider 312 slides from the first limiting wall a1 to the second limiting wall a2 or from the second limiting wall a2 to the first limiting wall a1, the geometric center point of the slider 312 slides 270 degrees within the groove 21a. Therefore, the arc of the groove 21a is 270 degrees plus the arc of the slider 312.

[0146] Please refer to Figures 6 and 32 together. When the protective shell is in the vertical support state, the second support part 320 is opened at an angle relative to the first support part 310. The slider 312 rotates in the slide groove 21a, causing the first support part 310 and the second support part 320 to rotate relative to the fixed part 20. The slider 312 rotates in the slide groove 21a until it abuts against the first limiting wall a1. When the protective shell 1 is placed on an object, the direction of the first supporting force F1 exerted by the object on the second support part 320 is in the X-axis direction, and thus the torque T1 of the first supporting force F1 on the bracket 30 is in the counterclockwise direction. The direction of the first holding force H1 of the first limiting wall a1 on the slider 312 is in the X-axis direction, and thus the torque T2 of the first holding force H1 on the bracket 30 is in the clockwise direction. The torque T1 of the first supporting force F1 on the bracket 30 is opposite to the torque T2 of the first holding force H1 on the bracket 30. Therefore, when the mobile terminal 2 is placed vertically on an object, the slider 312 of the protective case 1 abuts against the first limiting wall a1, and the torque T2 of the first supporting force H1 of the first limiting wall a1 on the slider 312 is opposite to the torque T1 of the first supporting force F1 of the object on the second supporting part 320, which prevents the bracket 30 from rotating relative to the mobile terminal 2 when the mobile terminal 2 is placed vertically, and enhances the support of the bracket 30 on the case body 10.

[0147] It should be noted that the torque mentioned in this application is the same as the torque itself. Torque is a vector quantity, having both magnitude and direction, and its unit is N·m. The magnitude of torque is the product of the force and the lever arm.

[0148] Please refer to Figures 7 and 33 together. When the protective shell is in the horizontal support state, the second support part 320 is opened at an angle relative to the first support part 310. The slider 312 rotates in the slide groove 21a, causing the first support part 310 and the second support part 320 to rotate relative to the fixed part 20. The slider 312 rotates in the slide groove 21a until it abuts against the second limiting wall a2. When the protective shell 1 is placed on an object, the direction of the second supporting force F2 exerted by the object on the second support part 320 is opposite to the Y-axis, and thus the torque T3 of the second supporting force F2 on the bracket 30 is clockwise. The direction of the second holding force H2 of the second limiting wall a2 on the slider 312 is opposite to the Y-axis, and thus the torque T4 of the second holding force H2 on the bracket 30 is counterclockwise. The torque T3 of the second supporting force F2 on the bracket 30 is opposite to the torque T4 of the second holding force H2 on the bracket 30. Therefore, when the mobile terminal 2 is placed horizontally on an object, the slider 312 abuts against the second limiting wall a2, and the torque T4 of the second supporting force H2 of the second limiting wall a2 on the slider 312 is opposite to the torque T3 of the second supporting force F2 of the object on the second supporting part 320, which prevents the bracket 30 from rotating relative to the mobile terminal 2 when the mobile terminal 2 is placed vertically, and enhances the support of the bracket 30 on the shell body 10.

[0149] It should be noted that in the vertical screen support state, the first limiting wall a1 can abut against the slider 312 alone, that is, the fixing plate 21 of the fixing part 20 does not have a hollowed-out part 21d, and the fixing part 20 does not include the abutment member 26. In the vertical screen support state, the first limiting wall a1 and the first abutting surface 26a of the abutment member 26 can also abut against the slider 312 together. Therefore, when the slider 312 abuts against the first limiting wall a1, the slider 312 also abuts against the first abutting surface 26a. The abutment member 26 is used to share the force of the slider 312 on the first limiting wall a1, preventing the slider 312 from damaging or scratching the first limiting wall a1.

[0150] It should also be noted that in the horizontal screen support state, the second limiting wall a2 can abut against the slider 312 independently, that is, the fixing plate 21 of the fixing part 20 does not have a hollowed-out portion, and the fixing part 20 does not include the abutment member 26. In the horizontal screen support state, the second limiting wall a2 and the second abutment surface 26b of the abutment member 26 can also abut against the slider 312 together. Therefore, when the slider 312 abuts against the second limiting wall a2, the slider 312 also abuts against the second abutment surface 26b. The abutment member 26 is used to share the force of the slider 312 on the second limiting wall a2, preventing the slider 312 from damaging or scratching the second limiting wall a2.

[0151] Please refer to Figure 34, which is a bottom view of the second support shown in Figure 2. Figure 35 is a cross-sectional view of the second support shown in Figure 34 along the VI-VI direction. Figure 36 is a structural diagram of the second support shown in Figure 34 after disassembly. For ease of illustration, the cross-sectional view in Figure 35 is tilted at a certain angle. The second support 320 includes a second support body 321, a enclosure 322, a second magnetic element 323, and a package 324. The enclosure 322, the second magnetic element 323, and the package 324 are all disposed on the second support body 321.

[0152] Since the second support portion 320 can rotate relative to the shell body 10 and the first support portion 310, the X-axis, Y-axis, and Z-axis directions are not shown in Figures 34 to 36. The second support portion 320 will be described below using the length direction, width direction, and thickness direction of the second support body 321, wherein the length direction, width direction, and thickness direction of the second support body 321 are perpendicular to each other.

[0153] Specifically, as shown in Figure 25, the second support 321 includes a first surface 3211 and a second surface 3212 disposed opposite to each other along the thickness direction of the second support portion 320. The second surface 3212 includes a first sub-surface 3212a, a second sub-surface 3212b, and a third sub-surface 3212c. The first sub-surface 3212a, the third sub-surface 3212c, and the second sub-surface 3212b are disposed sequentially along the length direction of the second support portion 320, and the first sub-surface 3212a, the second sub-surface 3212b, and the third sub-surface 3212c are all parallel to each other. The height of the first sub-surface 3212a in the thickness direction of the second support 321 is greater than the height of the third sub-surface 3212c in the thickness direction of the second support 321, and the height of the third sub-surface 3212c in the thickness direction of the second support 321 is greater than the height of the second sub-surface 3212b in the thickness direction of the second support 321. That is, the thickness of the second support 321 at the first sub-surface 3212a is greater than the thickness of the second support 321 at the third sub-surface 3212c, and the thickness of the second support 321 at the third sub-surface 3212c is greater than the thickness of the second support 321 at the second sub-surface 3212b.

[0154] Please refer to Figure 35. The second support 321 includes a second hinge seat 321a, which is one end of the second support 321 along its length and is located near the second sub-surface 3212b. That is, the first sub-surface 3212a, the third sub-surface 3212c, the second sub-surface 3212b, and the second hinge seat 321a are sequentially arranged along the length of the second support portion 320. As shown in Figure 37, which is a schematic diagram of the structure of the second hinge seat of the second support shown in Figure 34, the second hinge seat 321a has a second mounting hole that extends through the second hinge seat 321a along the width direction of the second support 321. In this application, there are two second hinge seats 321a, spaced apart along the width direction of the second support 321.

[0155] Please refer to Figures 34 to 36. The enclosure 322 is disposed around the second surface 3212 of the second support 321, and the enclosure 322 is fixedly connected to the second support 321. The enclosure 322 and the second support 321 can be integrally formed.

[0156] The second magnetic element 323 is disposed on the second sub-surface 3212b. The encapsulation element 324 is disposed on the surface of the second magnetic element 323 facing away from the second sub-surface 3212b, and is fixedly connected to the second support body 321, thus fixing the second magnetic element 323 to the second support body 321. The surface of the encapsulation element 324 facing away from the second magnetic element 323 may be flush with the first sub-surface 3212a.

[0157] Please refer to Figure 38, which is a cross-sectional view of the second support portion attached to the first support portion. When the second support portion 320 is attached to the first support portion 310, the first sub-surface 3212a is connected to the first contact sub-surface 3111a, the surface of the encapsulation member 324 facing away from the second magnetic member 323 is connected to the second contact sub-surface 3111b, and the third sub-surface 3212c is connected to the third contact surface 3111c. The orthographic projection of the first magnetic member 313 in the Z-axis direction coincides with the orthographic projection of the second magnetic member 323 in the Z-axis direction.

[0158] It should be noted that the magnetic attraction between the first magnetic element 313 and the second magnetic element 323 causes the second support portion 320 to adhere to the first support portion 310. The first magnetic element 313 is a permanent magnet, and the second magnetic element 323 can be a non-permanent magnet; or, the first magnetic element 313 is a non-permanent magnet, and the second magnetic element 323 is a permanent magnet; or, both the first magnetic element 313 and the second magnetic element 323 are permanent magnets. A permanent magnet is a magnet that can maintain its magnetism for a long time, while a non-permanent magnet is a magnet that can be magnetized under the influence of a magnetic field. The magnetic attraction between the first magnetic element 313 and the second magnetic element 323 prevents the second support portion 320 from opening relative to the first support portion 310.

[0159] Please refer to Figure 39, which is a schematic diagram of the disassembled structure of the first and second hinge seats. The two opposite ends of the rotating shaft 314 are respectively disposed in the second mounting holes of the two second hinge seats 321a, and the two first hinge seats 311a are located between the two second hinge seats 321a. The elastic element 315 is connected to both the first support body 311 and the second support body 321. When the second support body 321 is in contact with the first support body 311, the elastic element 315 is elastically compressed, and the release of elastic potential energy by the elastic element 315 causes the second support body 321 to open relative to the first support body 311.

[0160] For example, the elastic element 315 is a torsion spring, and the two torsion arms of the torsion spring are respectively connected to the first support 311 and the second support 321. The torsion spring is sleeved on the rotating shaft 314, which can enhance the fixation of the torsion spring and prevent the torsion spring from falling off. Moreover, the helical torsion spring also has the advantages of smooth torsion and long service life.

[0161] In this application, the rotating shaft 314 can be rotatably connected to at least one of the first hinge seat 311a and the second hinge seat 321a. That is, the rotating shaft 314 is rotatably connected to the first hinge seat 311a and fixedly connected to the second hinge seat 321a; or, the rotating shaft 314 is fixedly connected to the first hinge seat 311a and rotatably connected to the second hinge seat 321a; or, the rotating shaft 314 is rotatably connected to both the first and second hinge seats 321a. All three connection relationships between the rotating shaft 314 and the first hinge seat 311a and the second hinge seat 321a respectively allow the second support body 321 to rotate relative to the first support body 311, thereby allowing the second support body 321 to fit against the first support body 311 or to open at an angle relative to the first support body 311.

[0162] It should be noted that, under the action of external force, the second support portion 320 is attached to the first support portion 310, and the elastic member 315 is elastically compressed. When the second support portion 320 is attached to the first support portion 310, the torque of the magnetic force of the first magnetic member 313 on the second magnetic member 323 is greater than the torque of the elastic member 315 on the second support body 321, so that the second support portion 320 is stably attached to the first support portion 310, and the second support portion 320 will not open relative to the first support portion 310. Under the action of external force, the second support portion 320 is opened relative to the first support portion 310. When the second support portion 320 is relative to the first support portion 310, since the first magnetic member 313 and the second magnetic member 323 are far apart, the magnetic force between the first magnetic member 313 and the second magnetic member 323 can be ignored, the elastic member 315 is in a free state, and the torque of the elastic member 315 on the second support portion 320 can also be ignored. The elastic element 315 allows the second support portion 320 to open to a preset angle relative to the first support portion 310 without requiring manual opening. Furthermore, after the second support portion 320 opens relative to the first support portion 310, the elastic element 315 also prevents the second support portion 320 from rotating arbitrarily relative to the first support portion 310. That is, if the second support portion 320 rotates slightly relative to the first support portion 310, the elastic element 315 will be elastically compressed, causing the angle between the second support portion 320 and the first support portion 310 to return to the preset angle.

[0163] In summary, the terminal component provided in this application includes a protective shell 1 and a mobile terminal 2, with the mobile terminal 2 disposed within the protective shell 1. The protective shell 1 includes a shell body 10, a fixing part 20, and a bracket 30. The shell body 10 includes a first surface 10c and a second surface 10d, which are disposed opposite to each other along the thickness direction of the shell body 10. The fixing part 20 includes a fixing plate 21, which protrudes from the first surface 10c and is fixedly connected to the shell body 10. The fixing plate 21 has a sliding groove 21a facing away from the first surface 10c, and the sliding groove 21a includes a first limiting wall a1. The bracket 30 includes a first support portion 310 and a second support portion 320. The first support portion 310 includes a first support body 311 and a slider 312. The slider 312 is fixedly connected to the first support body 311 and slidably connected to the slide groove 21a. The first support portion 310 is disposed on the first surface 10c, and the first support body 311 covers the fixing plate 21. The second support portion 320 includes a second support body 321. One end of the second support body 321 is rotatably connected to one end of the first support body 311. The second support body 321 can open at an angle relative to the first support body 311 or can fit against the surface of the first support body 311 facing away from the shell body 10. The slider 312 can slide along the groove 21a, causing the first support part 310 and the second support part 320 to rotate relative to the shell body 10. The slider 312 can abut against the first limiting wall a1, and the torque T2 of the first holding force H1 of the first limiting wall a1 on the slider 312 is opposite to the torque T1 of the first supporting force F1 of the second support part 320. Therefore, when the mobile terminal 2 is placed vertically on an object, the slider 312 abuts against the first limiting wall a1, and the torque T2 of the first holding force H1 of the first limiting wall a1 on the slider 312 is opposite to the torque T1 of the first supporting force F1 of the object on the second support part 320. This prevents the bracket 30 from rotating relative to the mobile terminal 2 when the mobile terminal 2 is placed vertically, thus enhancing the support of the bracket 30 for the mobile terminal 2.
