[0014] In one embodiment, the first support portion further includes a scratch-resistant member that protrudes from the first support body. The scratch-resistant member is spaced apart from the slider, and the scratch-resistant member contacts the first surface such that the first support body is spaced apart from the housing body. The scratch-resistant member is capable of rotating relative to the housing body. The scratch-resistant member is used to space the first support body from the housing body to prevent the first support body from directly contacting the housing body. When the first support portion rotates relative to the housing body, it prevents the first support portion from scratching the housing body or the housing body from scratching the first support portion.

[0015] In one embodiment, the first support body is provided with a receiving groove whose opening faces the housing body. The fixed disk is disposed in the receiving groove. The slider is fixedly connected to the bottom wall of the receiving groove, and the opening of the sliding groove faces the bottom wall of the receiving groove. The first support body has the receiving groove for receiving the fixed disk, so that the first support body can protect the fixed disk and also reduce the overall thickness of the fixing portion and the bracket.

[0016] In one embodiment, the fixed disk is provided with a mounting groove whose opening faces the bottom wall of the receiving groove. The mounting groove is spaced apart from the sliding groove. The fixing portion further includes a flexible member disposed in the mounting groove. Wherein, the flexible member is fixedly connected to the fixed disk and slidably connected to the bottom wall of the receiving groove; or the flexible member is slidably connected to the fixed disk and fixedly connected to the bottom wall of the receiving groove. The flexible member is connected to the fixed disk and the first support body respectively. The flexible member can increase the friction force required to overcome when the first support body rotates relative to the fixed disk, and prevent the first support portion and the second support portion from rotating due to a small external force.

[0017] In one embodiment, the first support portion further includes a damping member 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 the damping member is capable of rotating around the outer periphery of the fixed disk.

The second damping body is spaced from the side wall of the accommodating groove, and the second damping body elastically abuts against the fixed disk. The third damping body is spaced from the side wall of the accommodating groove, and the third damping body elastically abuts against the fixed disk. By fixedly connecting the first damping body, the fourth damping body, and the fifth damping body to the side wall of the accommodating groove, the damping member is fixed to the side wall of the accommodating groove. By spacing the second damping body and the third damping body from the side wall of the accommodating groove respectively, the second damping body and the third damping body have a certain deformation space, so that the damping member elastically abuts against the fixed disk.

[0019] In one embodiment, the first damping body and the fourth damping body are opposite and spaced along the width direction of the first support body. The first damping body and the fifth damping body are opposite and spaced along the width direction of the first support body. The second damping body and the third damping body are opposite and spaced along the length direction of the first support body. By the relatively arranged first damping body and fourth damping body and the relatively arranged first damping body and fifth damping body, the connection between the damping member and the side wall of the accommodating groove is made more stable. By the relatively arranged second damping body and third damping body clamping the fixed disk elastically respectively, the elastic abutment between the damping member and the fixed disk is made more stable.

[0020] In one embodiment, the housing body is provided with a first assembly hole penetrating through the first surface and the second surface. The fixed disk is provided with a second assembly hole penetrating through the fixed disk. The second assembly hole is communicated with the first assembly hole, and the center line of the second assembly hole is aligned with the center line of the first assembly hole. The first support portion further includes a connecting member. The connecting member is fixedly connected to the bottom wall of the accommodating groove. The connecting member is spaced from the slider. The connecting member is disposed in the first assembly hole and the second assembly hole, and the connecting member can rotate relative to the first assembly hole and the second assembly hole. By disposing the connecting member in the first assembly hole and the second assembly hole, the connection stability between the first support portion and the fixed disk is enhanced.

[0021] In one embodiment, the connecting member abuts against the second surface along the direction pointing from the second surface to the first surface. By abutting the connecting member against the second surface, the first support portion can be prevented from detaching from the housing body.

[0022] In one embodiment, a recess is formed in the second surface of the housing body, the notch of the recess faces away from the fixing plate, and one end of the connecting member facing away from the bottom wall of the accommodating groove is disposed in the recess. This avoids the portion of the connecting member located on the second surface from protruding from the housing body.

The rotating shaft is disposed between the first hinge seat and the second hinge seat, and the rotating shaft is rotatably connected to the first hinge seat and / or the second hinge seat. The elastic member is respectively connected to the first support body and the second support body. Wherein, when the second support body abuts against the first support body, the elastic member is elastically compressed, and the elastic member releases elastic potential energy to enable the second support body to open relative to the first support body to a preset angle. By the elastic member releasing elastic potential energy, the angle between the second support body and the first support body is automatically the preset angle, without manually rotating the second support body to make the angle between the second support body and the first support body the preset angle.

[0026] In some embodiments, the elastic member is a torsion spring. The torsion spring is sleeved on the rotating shaft, and the two torsion arms of the torsion spring are respectively connected to the first support body and the second support body. By sleeving the torsion spring on the rotating shaft, the fixing of the torsion spring can be enhanced to avoid the torsion spring from detaching. Moreover, the spiral torsion spring also has the advantages of smooth torsion and long service life.

[0027] In one embodiment, the first support portion further includes a first magnetic member disposed on the first support body. The second support portion further includes a second magnetic member disposed on the second support body. Wherein, the first magnetic member and the second magnetic member are magnetically attracted to make the second support body fit against the first support body. By the magnetic attraction force between the first magnetic member and the second magnetic member, the second support body is prevented from opening relative to the first support body without an external force.

[0028] In some embodiments, the first magnetic member is a permanent magnet and the second magnetic member is a non-permanent magnet; alternatively, the first magnetic member is a non-permanent magnet and the second magnetic member is a permanent magnet; or, both the first magnetic member and the second magnetic member are permanent magnets.

[0029] In some embodiments, when the second support portion fits against the first support portion, the moment of the magnetic force of the first magnetic member on the second magnetic member is greater than the moment of the elastic member on the second support body, so that the second support portion stably fits against the first support portion.

[0030] In a second aspect, an embodiment of the present application provides a terminal assembly, which includes a mobile terminal and the above-mentioned protective case, and the mobile terminal is disposed inside the protective case.

[0031] In summary, the terminal assembly provided by the embodiment of the present application includes a mobile terminal and a protective case. When the mobile terminal is placed vertically on an object, the slider abuts against the first limiting wall, and the moment of the first abutting force of the first limiting wall on the slider is opposite to the moment of the first supporting force of the object on the second support portion, thereby 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.

[0072] The terms "first", "second", etc. are used for descriptive purposes only and do not have any order or technical meaning, nor can they be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. The directional terms mentioned in this application, such as "up", "down", "front", "back", "left", "right", "inside", "outside", etc., are only with reference to the orientations shown in the accompanying drawings. In addition, the "clockwise" and "counterclockwise" mentioned in this application are also with reference to the orientations shown in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the present application, rather than indicating the orientation of the device or component referred to in the actual application scenario.

[0073] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. 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. Among them, "fixed connection" means that the two are connected to each other and the relative position relationship after the connection remains unchanged. "Rotational connection" means that the two are connected to each other and can rotate relative to each other after the connection. "Sliding connection" means that the two are connected to each other and can slide relative to each other after the connection.

[0074] In the embodiments of the present application, "and / or" is merely a description of the association relationship between associated objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this text, the character " / " generally represents an "or" relationship between the associated objects before and after.

[0075] The limitations such as the terms "parallel" and "perpendicular" are in the context of the current technological level, rather than the absolutely strict definitions in the mathematical sense. A small deviation is allowed, and being approximately parallel or approximately perpendicular, etc. are all acceptable. For example, when A is parallel to B, it means that A is parallel to B or approximately parallel to B, and the included angle between A and B can be between 0 degrees and 5 degrees. Another example, when A is perpendicular to B, it means that A is perpendicular to B or approximately perpendicular to B, and the included angle between A and B can be between 85 degrees and 95 degrees.

That is to say, Figure 6 after the bracket 30 in it rotates 270 degrees clockwise as Figure 7 shown, Figure 7 after the bracket 30 in it rotates 270 degrees counterclockwise as Figure 6 shown. Figure 6 in and Figure 7 , after the bracket 30 is opened, the second support portion 320 and the case body 10 are placed on something to realize the support of the protective case 1 for the mobile terminal 2.

[0085] 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 60 degrees to 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. The present application does not make specific limitations on this. It can be understood that when the preset angle between the second support portion 320 and the first support portion 310 is 90 degrees, the connection stability between the second support portion 320 and the first support portion 310 is better, and it can avoid the support force of something on the second support portion 320 causing the second support portion 320 to rotate relative to the first support portion 310.

[0086] Please refer to Figures 6 to 8 , Figure 8Front view structural schematic diagram of the shell body disclosed in the embodiments of the present 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. Among them, the bottom surface 10a and the top surface 10b are arranged in opposite directions along the X-axis direction, the first surface 10c and the second surface 10d are arranged in opposite directions along the Z-axis direction, and the first side surface 10e and the second side surface 10f are arranged in opposite directions along the Y-axis direction.

The length and width of the shell body 10 are determined according to the size of the mobile terminal 2. On the basis of meeting the structural strength of the protective shell 1, the thickness of the shell body 10 can be appropriately reduced to avoid overly increasing the thickness of the terminal components. The shell edge body is of a frame structure. On the basis of meeting the structural strength of the protective shell 1, the wall thickness of the shell edge body can also be appropriately reduced to avoid overly increasing the length and width of the terminal components.

The light-transmitting hole 12 is closer to the top surface 10b than the first assembly hole 13, and the first assembly hole 13 is closer to the bottom surface 10a than the light-transmitting hole 12. That is, the bottom surface 10a, the first assembly hole 13, the light-transmitting hole 12, and the top surface 10b are arranged in sequence along the X-axis direction. The first assembly hole 13 is a cylindrical through-hole, and the number thereof is one.

[0091] Please refer to Figure 9 , the limiting hole 14 penetrates through the first surface 10c and the second surface 10d.

The recess 16 can be considered as the second surface 10d located in the mounting area 19 being concave in the Z-axis direction. Moreover, the first surface 10c located in the mounting area 19 is convex in the Z-axis direction, so as to avoid the thickness of the shell body 10 in the mounting area 19 being reduced due to the recess 16 in the mounting area 19, thereby avoiding the reduction of the structural strength of the shell body 10.

[0097] The sliding groove 21a is opened on the first assembly surface 211 of the fixing plate 21, and the sliding groove 21a is spaced from the second assembly hole 21c and the mounting groove 21b respectively. Among them, the sliding groove 21a is an arc-shaped groove, and the sliding groove 21a extends around the center line of the second assembly hole 21c. The center line of the sliding groove 21a is aligned with the center line of the second assembly hole 21c. The radius corresponding to the sliding groove 21a is greater than the radius corresponding to the mounting groove 21b, that is, the mounting groove 21b is closer to the second assembly hole 21c than the sliding groove 21a. The groove side wall of the sliding groove is arc-shaped, and the radian of the arc is greater than 270 degrees and less than 360 degrees. It can be considered that the extension path of the sliding groove 21a is an arc, and the radian of this arc is greater than 270 degrees and less than 360 degrees. The sliding 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 respectively two wall surfaces in the extending direction of the sliding groove 21a. That is to say, the sliding groove 21a extends from the first limiting wall a1 to the second limiting wall a2. Moreover, from the slider 312 abutted against the first limiting wall a1 to the slider 312 abutted against the second limiting wall a2, the slider 312 needs to rotate 270 degrees in the sliding groove 21a.

The hollow part 21d is opened inside the fixing disk 21. The first limiting wall a1 is provided with a first opening a11, and the second limiting wall a2 is provided with a second opening a21. The hollow part 21d is respectively communicated with the first opening a11 and the second opening a21, so that the hollow part 21d is communicated with the sliding groove 21a. The first limiting wall a1 exposes the hollow part 21d, and the second limiting wall a2 exposes the hollow part 21d. It can be considered that the extension path of the hollow part 21d is also an arc, and 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 radian of the arc corresponding to the hollow part 21d and the radian of the corresponding arc of the sliding groove 21a is 360 degrees. That is, the hollow part 21d and the sliding groove 21a together form an annular notch.

[0099] Exemplarily, please refer to Figure 11 and Figure 18 , the hollow part 21d includes a first hollow sub-part d1, a second hollow sub-part d2 and a third hollow sub-part d3. The first hollow sub-part d1 is arranged close to the first limiting wall a1, and the first hollow sub-part d1 is communicated with the first opening a11, so that the sliding groove 21a is communicated with the first hollow sub-part d1. The first hollow sub-part d1 penetrates through the first assembly surface 211 and the second assembly surface 212 of the fixing disk 21. In other embodiments, the first hollow sub-part d1 may not penetrate through the first assembly surface 211 and the second assembly surface 212 of the fixing disk 21, or penetrate through the first assembly surface 211 or the second assembly surface 212 of the fixing disk 21. The present application does not make specific limitations on this.

[0100] Please refer to Figure 12 and Figure 18 , the second hollow sub-part d2 is arranged close to the second limiting wall a2, the second hollow sub-part d2 is spaced from the first hollow sub-part d1, and the second hollow sub-part d2 is communicated with the second opening a21, so that the sliding groove 21a is communicated with the second hollow sub-part d2. The second hollow sub-part d2 penetrates through the first assembly surface 211 and the second assembly surface 212 of the fixing disk 21. In other embodiments, the second hollow sub-part d2 may not penetrate through the first assembly surface 211 and the second assembly surface 212 of the fixing disk 21, or penetrate through the first assembly surface 211 or the second assembly surface 212 of the fixing disk 21. The present application does not make specific limitations on this.

[0101] As Figure 18 shown, the third hollow sub-part d3 is arranged between the first hollow sub-part d1 and the second hollow sub-part d2, and the third hollow sub-part d3 is respectively communicated with the second hollow sub-part d2 and the third hollow sub-part d3. The third hollow sub-part d3 does not penetrate through the first assembly surface 211 and the second assembly surface 212 of the fixing disk 21.

[0102] Please refer to Figure 11 , Figure 15With Figure 16 The flexible member 22 is annular. The flexible member 22 is disposed in the mounting groove 21b. The flexible member 22 is detachably connected to the fixed disk 21. The surface of the flexible member 22 facing away from the bottom of the mounting groove 21b extends beyond the first assembly surface 211, that is, the surface of the flexible member 22 facing away from the bottom of the mounting groove 21b extends beyond the notch of the mounting groove 21b. That is to say, 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 disk 21.

[0103] It should be noted that the flexible member 22 can be made of an elastic material. The flexible member 22 will deform under an external force and return to its original state after the external force is removed.

[0104] Please refer to Figure 11 、 Figure 14 With Figure 15 The limiting member 23 and the anti-fooling member 25 both protrude from the second assembly surface 212 of the fixed disk 21, and both the limiting member 23 and the anti-fooling member 25 are fixedly connected to the fixed disk 21. Further, the fixed disk 21 and the limiting member 23 can be integrally formed, and the fixed disk 21 and the anti-fooling member 25 are integrally formed.

[0105] Exemplarily, as Figure 14 shown, the number of the limiting members 23 is 4. The 4 limiting members 23 are arranged around the center line of the second assembly hole 21c. Among them, two limiting members 23 are arranged at intervals along the X-axis direction, and the other two limiting members 23 are arranged at intervals along the Y-axis direction. In other embodiments, the number of the limiting members 23 can also be 1, 2, 3, or more than 4. The present application does not specifically limit the number of the limiting members 23.

[0106] The anti-fooling member 25 is cylindrical, and the number of the anti-fooling members 25 is 2. The center points between the two anti-fooling members 25 are not on the center line of the second assembly hole 21c. The two anti-fooling members 25 are respectively close to the two limiting members 23 arranged along the Y-axis direction. In other embodiments, the number of the anti-fooling members 25 can also be 3, 4, or other more numbers. The present application does not specifically limit this, as long as the center points between the multiple anti-fooling members 25 are not on the center line of the second assembly hole 21c.

[0107] Please refer to Figure 11 、 Figure 12 With Figure 18 The abutting member 26 is disposed in the hollow portion 21d. The abutting member 26 includes a first abutting surface 26a and a second abutting surface 26b arranged opposite to each other. As Figure 11 With Figure 18 shown, the first abutting surface 26a is located at the first opening a11, and the first limiting wall a1 is flush with the first abutting surface 26a. As Figure 12 With Figure 18, the second abutting surface 26b is located at the second opening a21, and the second limiting wall a2 is flush with the second abutting surface 26b.

[0108] Please refer to Figure 19 and Figure 20 , Figure 19 is Figure 16 a three-dimensional structural schematic diagram of a perspective view of the middle abutting member, Figure 20 is Figure 16 a three-dimensional structural schematic diagram of another perspective view of the middle abutting member. The abutting member 26 includes a first abutting sub-member 261, a second abutting sub-member 262, and a third abutting sub-member 263. The first abutting surface 26a is one side surface of the circumferential side surface of the first abutting sub-member 261, and the second abutting surface 26b is one side surface of the circumferential side surface of the second abutting sub-member 262. The opposite ends of the third abutting sub-member 263 are respectively connected to the first abutting sub-member 261 and the second abutting sub-member 262, and the third abutting sub-member 263 is connected to the side surface of the first abutting sub-member 261 except the first abutting surface 26a, and the third abutting sub-member 263 is connected to the side surface of the second abutting sub-member 262 except the second abutting surface 26b. The third abutting sub-member 263 is used to fix the first abutting sub-member 261 and the second abutting sub-member 262 to the fixed disk 21.

[0109] Please refer to Figure 18 , the first abutting sub-member 261 is disposed in the first hollowed-out sub-part d1, the second abutting sub-member 262 is disposed in the second hollowed-out sub-part d2, and the third abutting sub-member 263 is disposed in the third hollowed-out sub-part d3. As Figure 13 shown, the first abutting sub-member 261 exposes the first assembly surface 211, and the surface of the first abutting sub-member 261 that exposes the first assembly surface 211 is flush with the first assembly surface 211. The second abutting sub-member 262 exposes the first assembly surface 211, and the surface of the second abutting sub-member 262 that exposes the first assembly surface 211 is flush with the first assembly surface 211. As Figure 14 shown, the first abutting sub-member 261 exposes the second assembly surface 212, and the surface of the first abutting sub-member 261 that exposes the second assembly surface 212 is flush with the second assembly surface 212. The second abutting sub-member 262 exposes the second assembly surface 212, and the surface of the second abutting sub-member 262 that exposes the second assembly surface 212 is flush with the second assembly surface 212. In other embodiments, the first abutting sub-member 261 may not expose the first assembly surface 211 and / or the second assembly surface 212, and the second abutting sub-member 262 may not expose the first assembly surface 211 and / or the second assembly surface 212. This application does not make specific limitations in this regard. In this application, the third abutting sub-member 263 does not expose the first assembly surface 211 and the second assembly surface 212.

[0110] It should be noted that, as Figures 18 to 20As shown, the surface of the third abutting sub-component 263 is also provided with a plurality of protrusions. Correspondingly, a plurality of depressions are formed on the inner wall of the third hollowed-out sub-part d3. The positions of the depressions correspond to the positions of the protrusions one by one, the shapes of the depressions correspond to the shapes of the protrusions one by one, and the sizes of the depressions correspond to the sizes of the protrusions one by one. One protrusion is disposed within one depression. It can be understood that disposing the protrusion within the depression can enhance the connection between the third abutting sub-component 263 and the fixed disk 21, and further enhance the connection between the abutting component 26 and the fixed disk 21.

[0111] It should also be noted that the material of the abutting component 26 includes metal. Further, the material of the abutting component 26 includes aluminum alloy. The first abutting sub-component 261, the second abutting sub-component 262 and the third abutting sub-component 263 are integrally formed. The material of the fixed disk 21 includes plastic. The fixed disk 21 is formed by injection molding, so that the abutting component 26 is located inside the fixed disk 21. That is, the abutting component 26 is first formed, and then the abutting component 26 is placed into the mold for forming the fixed disk 21, and the fixed disk 21 is formed in the mold by injection molding.

[0112] Please refer to Figure 21 , Figure 21 FIG. is a schematic structural view of a perspective of the fixing part assembled to the housing body. The fixed disk 21 is disposed on the first surface 10c. That is, the second assembly surface 212 of the fixed disk 21 is connected to the first surface 10c of the housing body 10. The first assembly surface 211 of the fixed disk 21 and the first surface 10c of the housing body 10 both face the Z-axis direction. The notch of the sliding groove 21a and the notch of the mounting groove 21b both face away from the second surface 10d. That is, the orientation of the notch of the sliding groove 21a is the same as the orientation of the first surface 10c, and the orientation of the notch of the mounting groove 21b is the same as the orientation of the first surface 10c.

[0113] Please refer to Figure 22 , Figure 22 FIG. is a schematic structural view of another perspective of the fixing part assembled to the housing body. One limiting member 23 is disposed within one limiting hole 14, and one anti-fooling member 25 is disposed within one anti-fooling hole 15. The end of the limiting member 23 facing away from the fixed disk 21 and the end of the anti-fooling member 25 facing away from the fixed disk 21 are both located within the recess 16. The center line of the second assembly hole 21c coincides with the center line of the first assembly hole 13.

[0114] Understandably, the limiting member 23 has two ends arranged in opposite directions, and the size of one end is larger than that of the other end. The end with a larger size of the limiting member 23 is connected to the fixed disk 21, and the end with a smaller size of the limiting member 23 is the end of the limiting member 23 facing away from the fixed disk 21. The end with a smaller size of the limiting member 23 is conducive to aligning the limiting member 23 with the limiting hole 14, facilitating the assembly of the limiting member 23 into the limiting hole 14. The end of the anti-fooling member 25 facing away from the fixed disk 21 is a hemisphere or semi-ellipsoid, and the size of the end of the anti-fooling member 25 facing away from the fixed disk 21 is smaller, which is conducive to aligning the anti-fooling member 25 with the anti-fooling hole 15, facilitating the assembly of the anti-fooling member 25 into the anti-fooling hole 15.

[0115] It can also be understood that by assembling the anti-fooling member 25 into the anti-fooling hole 15, the assembly relationship between the fixing part 20 and the housing body 10 is unique. That is, after the fixing part 20 is assembled to the housing body 10, there is only one orientation of the fixing part 20 relative to the housing body 10, so that the fixing part 20 is arranged on the housing body 10 in the correct orientation.

[0116] It should be noted that assembling the limiting member 23 into the limiting hole 14 can limit the rotation of the fixing part 20 relative to the housing body 10. Assembling the anti-fooling member 25 into the anti-fooling hole 15 can also limit the rotation of the fixing part 20 relative to the housing body 10. However, the fixing part 20 can be detached from the housing body 10 along the direction pointing from the second surface 10d to the first surface 10c (Z-axis direction). In this application, the materials of the limiting member 23 and the anti-fooling member 25 are both thermoplastic materials. After the limiting member 23 is assembled into the limiting hole 14 and the anti-fooling member 25 is assembled into the anti-fooling hole 15, the limiting member 23 and the anti-fooling member 25 are deformed through a thermoplastic process. The deformed limiting member 23 is fixed to the housing body 10 and the deformed anti-fooling member 25 is fixed to the housing body 10, and the fixing part 20 cannot be detached from the housing body 10 along the direction pointing from the second surface 10d to the first surface 10c either.

[0117] Please refer to Figures 23 to 27 , Figure 23 is Figure 2 the top view structural schematic diagram of the first support part shown in Figure 24 is Figure 23 the bottom view structural schematic diagram of the first support part shown in Figure 25 is Figure 23 the front view structural schematic diagram of the first support part shown in Figure 26 is Figure 25 the structural schematic diagram of a perspective view of the disassembled first support part shown in Figure 27 is Figure 25Schematic structural diagram of another perspective after the decomposition of the shown first support part. In the present application, the first support part 310 includes a first support body 311, a slider 312, a first magnetic member 313, a rotating shaft 314, an elastic member 315, a damping member 316, a connecting member 317, and a scratch-proof member 318. The slider 312, the first magnetic member 313, the rotating shaft 314, the elastic member 315, the damping member 316, the connecting member 317, and the scratch-proof member 318 are all arranged on the first support body 311, and the first magnetic member 313, the rotating shaft 314, the elastic member 315, the damping member 316, the connecting member 317, and the scratch-proof member 318 are spaced apart from the slider 312 respectively.

[0118] Since the first support part 310 can rotate relative to the housing body 10, therefore Figures 23 to 25 only the schematic in the Z-axis direction is given below. Hereinafter, the length direction, the width direction, and the thickness direction of the first support body 311 are used to describe the first support part 310, wherein the thickness direction of the first support body 311 is parallel to the Z-axis direction, and the length direction, the width direction, and the thickness direction of the first support body 311 are perpendicular to each other in pairs.

[0119] Specifically, please refer to Figures 23 to 25 , the first support body 311 includes a first contact surface 3111 and a second contact surface 3112 which are arranged opposite to each other along the thickness direction of the first support body 311. As shown in Figure 23 and Figure 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 sub-surface 3111c, and the third contact sub-surface 3111c are arranged in sequence along the length direction of the first support body 311, and the first contact sub-surface 3111a, the second contact sub-surface 3111b, and the third contact sub-surface 3111c are all parallel to each other.

[0120] The first contact sub-surface 3111a and the second contact sub-surface 3111b have the same height in the thickness direction of the first support body 311, the height of the third contact sub-surface 3111c in the thickness direction of the first support body 311 is greater than the height of the first contact sub-surface 3111a, and the height of the third contact sub-surface 3111c in the thickness direction of the first support body 311 is greater than the height of the second contact sub-surface 3111b. That is to say, the thickness of the first support body 311 at the first contact sub-surface 3111a is the same as the thickness of the first support body 311 at the second contact sub-surface 3111b, and the thickness of the first support body 311 at the third contact sub-surface 3111c is greater than the thickness of the first support body 311 at the first contact sub-surface 3111a and greater than the thickness of the first support body 311 at the second contact sub-surface 3111b.

[0121] Please refer to Figure 24 , a receiving groove 311c is formed in the second contact surface 3112 of the first support 311. The number of the receiving grooves 311c is 1, and the receiving groove 311c is a cylindrical groove.

[0122] 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 sub-surface 3111c in the thickness direction of the first support 311. It can be understood that precisely because the receiving groove 311c needs to be formed, the thickness of the first support 311 at the third contact sub-surface 3111c is made greater than the thickness of the first support 311 at the first contact sub-surface 3111a and greater than the thickness of the first support 311 at the second contact sub-surface 3111b, so as to avoid reducing the structural strength of the first support 311 due to the formation of the receiving groove 311c.

[0123] Please refer to Figure 28 , Figure 28 is Figure 24 an enlarged schematic view of Structure IV in the first support shown in. In the present application, the damping member 316 is disposed in the receiving groove 311c, and the damping member 316 is fixedly connected to the side wall of the receiving groove 311c. Among them, the interference fit between the damping member 316 and the receiving groove 311c or the bonding of the damping member 316 to the side wall of the receiving groove 311c fixes the damping member 316 to the side wall of the receiving groove 311c. Specifically, the damping member 316 is an unclosed ring, which includes 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 opposite and spaced apart along the width direction of the first support 311, the first damping body 3161 and the fifth damping body 3165 are opposite and spaced apart along the width direction of the first support 311, and the second damping body 3162 and the third damping body 3163 are spaced apart along the length direction of the first support 311. 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, opposite ends of the third damping body 3163 are respectively connected to the other end of the first damping 3161 and one end of the fifth damping body 3165, and the end of the fourth damping body 3164 facing away from the second damping body 3162 is spaced 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 in sequence in the clockwise direction. The gap between the fourth damping body 3164 and the fifth damping body 3165 is also the unclosed part of the damping member 316.

[0124] 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 segments. The radius of the outer arc surface of the first damping body 3161 is equal to the radius of the accommodation groove 311c, so that the outer arc surface of the first damping body 3161 is connected to the side wall of the accommodation groove 311c. The radius of the outer arc surface of the fourth damping body 3164 is equal to the radius of the accommodation groove 311c, so that the outer arc surface of the fourth damping body 3164 is connected to the side wall of the accommodation groove 311c. The radius of the outer arc surface of the fifth damping body 3165 is equal to the radius of the accommodation groove 311c, so that the outer arc surface of the fifth damping body 3165 is connected to the side wall of the accommodation groove 311c. The radius of the outer arc surface of the second damping body 3162 is smaller than the radius of the accommodation groove 311c, so that there is a gap between the outer arc surface of the second damping body 3162 and the accommodation groove 311c. The radius of the outer arc surface of the third damping body 3163 is smaller than the radius of the accommodation groove 311c, so that there is a gap between the outer arc surface of the third damping body 3163 and the accommodation groove 311c.

[0125] It should be noted that the damping member 316 is fixedly connected to the side wall of the accommodation groove 311c through the first damping body 3161, the fourth damping body 3164 and the fifth damping body 3165, so that the damping member 316 is fixed to the side wall of the accommodation groove 311c. Moreover, through the relatively arranged first damping body 3161 and the fourth damping body 3164 and the relatively arranged first damping body 3161 and the fifth damping body 3165, the connection between the damping member 316 and the side wall of the accommodation groove 311c is made more stable.

[0126] It also should be noted that a contact body 319 is provided on the side wall of the accommodation groove 311c. The contact body 319 is located between the fourth damping body 3164 and the fifth damping body 3165, and the contact body 319 is fixedly connected to the side wall of the accommodation groove 311c. The contact body 319 can enhance the fixation between the side wall of the accommodation groove 311c and the damping member 316 and prevent the damping member 316 from falling off the side wall of the accommodation groove 311c. Among them, the contact body 319 and the first support body 311 are integrally formed.

[0127] The slider 312 is arranged on the bottom wall of the accommodation groove 311c, and the slider 312 is fixedly connected to the bottom wall of the accommodation groove 311c. The slider 312 is an arc block, that is, the extension path of the slider 312 is an arc, and the radian of the arc is less than 90 degrees. Among them, the slider 312 and the first support body 311 are integrally formed.

[0128] Please refer to Figures 26 to 28, the connecting member 317 is disposed in the receiving groove 311c. Specifically, the connecting member 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, extends towards the notch of the receiving groove 311c, and one end of the fixed shaft 3171 facing away from the bottom wall of the receiving groove 311c extends out of the notch of the receiving groove 311c. The fixed shaft 3171 is a stepped shaft, which includes 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 one end of the first fixed sub-shaft 3171a facing away from the bottom wall of the receiving groove 311c. Among them, the fixed shaft 3171 and the first support 311 are integrally formed.

[0129] 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 circumferential direction 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. Among them, 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.

[0130] Please refer to Figure 24 and Figure 27 , a first fixing groove 311d and a second fixing groove 311e are formed on the second contact surface 3112 of the first support 311. 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 sub-surface 3111a in the thickness direction of the first support 311, and 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 sub-surface 3111b in the thickness direction of the first support 311.

[0131] In this application, the number of the first magnetic members 313 is 1, and the number of the anti-scratch members 318 is 2. For easy distinction, one anti-scratch member 318 is defined as the first anti-scratch member 318a, and the other anti-scratch member is defined as the second anti-scratch member 318b. As Figure 27As shown, the first scratch-resistant member 318a is disposed in the first fixing groove 311d, and the surface of the first scratch-resistant member 318a facing away from the bottom wall of the first fixing groove 311d protrudes from the second contact surface 3112. That is, a part of the first scratch-resistant member 318a is disposed in the first fixing groove 311d, and another part of the first scratch-resistant member 318a protrudes from the second contact surface 3112. The first magnetic member 313 is disposed on the bottom wall of the second fixing groove 311e, and the thickness of the first magnetic member 313 is less than the depth of the second fixing groove 311e. The second scratch-resistant member 318b is disposed in the second fixing groove 311e, and the second scratch-resistant member 318b 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 scratch-resistant member 318b facing away from the first magnetic member 313 protrudes from the second contact surface 3112. That is, a part of the second scratch-resistant member 318b is disposed in the second fixing groove 311e, and another part of the second scratch-resistant member 318b protrudes from the second contact surface 3112. Among them, the thickness of the first scratch-resistant member 318a protruding from the second contact surface 3112 is the same as the thickness of the second scratch-resistant member 318b protruding from the second contact surface 3112. The scratch-resistant member 318 can be made of an elastic material, so that the scratch-resistant member 318 has a certain deformation ability.

[0132] Specifically, please refer to Figure 29 , Figure 29 FIG. is a schematic structural view of the rotating shaft assembled to the first support body. The first support body 311 includes a first hinge seat 311a. The first hinge seat 311a is one end in the length direction of the first support body 311, and the first hinge seat 311a is close to the second contact sub-surface 3111b. That is, the first contact sub-surface 3111a, the third contact sub-surface 3111c, the second contact sub-surface 3111b and the first hinge seat 311a are arranged in sequence along the length direction of the first support body 311. The first hinge seat 311a has a first mounting hole, and the first mounting hole penetrates the first hinge seat 311a along the width direction of the first support body 311. In this application, the number of the first hinge seats 311a is two, and the two first hinge seats 311a are arranged at intervals along the width direction of the first support body 311. In other embodiments, the number of the first hinge seats 311a may also be greater than two.

[0133] The rotating shaft 314 is disposed in the first mounting holes of the two first hinge seats 311a, and the opposite ends of the rotating shaft 314 respectively protrude from the first hinge seats 311a. The elastic member 315 is connected to the first support body 311. In this application, the elastic member 315 is a torsion spring. The torsion spring is disposed between the two first hinge seats 311a. The torsion spring is 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 member 315 may also be a leaf spring, a helical spring, etc., and this application does not make specific limitations on this.

[0134] Please refer to Figure 30With Figure 31 , Figure 30 FIG. Figure 30 is a schematic structural view of the first support member and the fixing portion after assembly, Figure 31 and Figure 30 FIG. Figure 30 is a schematic cross-sectional view of the first support member and the fixing portion shown in FIG. Figure 31 along the V-V direction. For the sake of easy display, Figure 30 the housing body 10 is omitted in FIG. Figure 31 , Figure 31 and the housing body 10 is present in FIG. Figure 31 . In the present application, the first support body 311 is disposed on the first surface 10c, and the first support body 311 covers the fixing disk 21. The notch of the accommodating groove 311c faces the first surface 10c, and the fixing disk 21 is located in the accommodating groove 311c. The notch of the sliding groove 21a of the fixing disk 21 and the notch of the mounting groove 21b both face the bottom wall of the accommodating groove 311c, and the flexible member 22 is connected to the bottom wall of the accommodating groove 311c.

[0135] It can be understood that the first support body 311 has an accommodating groove 311c for accommodating the fixing disk 21, so that the first support body 311 can protect the fixing disk 21 and can also reduce the overall thickness of the fixing portion 20 and the bracket 30.

[0136] The center line of the first assembly hole 13 is aligned with the center line of the second assembly hole 21c, and the first assembly hole 13 communicates with the second assembly hole 21c. The connecting member 317 is disposed in the first assembly hole 13, the second assembly hole 21c, and the recess 16, and the connecting member 317 has a clearance fit with the peripheral walls of the first assembly hole 13, the second assembly hole 21c, and the recess 16, so that the connecting member 317 can rotate relative to the fixing disk 21 and the housing body 10, and thus the first support portion 310 and the second support portion 320 can rotate relative to the fixing disk 21. Specifically, the first fixing sub-axis 3171a is disposed in the second assembly hole 21c, and the second fixing sub-axis 3171b is disposed in the second assembly hole 21c, the first assembly hole 13, and the recess 16. The bushing 3172 is disposed in the second assembly hole 21c and the recess 16. The first sleeve body 3172a is disposed in the first assembly hole 13, and the second sleeve body 3172b is disposed in the recess 16. The connecting member 317 abuts against the second surface 10d along the direction from the second surface 10d to the first surface 10c, that is, the second sleeve body 3172b abuts against the second surface 10d along the direction from the second surface 10d to the first surface 10c, and the bottom of the recess 16 is also a part of the second surface 10d.

[0137] Understandably, by disposing the connecting member 317 in the first assembly hole 13 and the second assembly hole 21c, the connection stability between the first support portion 310 and the fixing portion 20 is enhanced. By abutting the connecting member 317 against the second surface 10d, the first support portion 310 can be prevented from detaching from the housing body 10. Moreover, one end of the connecting member 317 facing away from the bottom wall of the receiving groove 311c is disposed in the recess 16, preventing the portion of the connecting member 317 located on the second surface 10d from protruding from the housing body 10.

[0138] It should be noted that during the assembly of the first support body 311 to the housing body 10, the fixed shaft 3171 and the bushing 3172 are separated. First, the fixed shaft 3171 is assembled from the first surface 10c into the first assembly hole 13, the second assembly 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 assembly hole 13.

[0139] 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, that is, 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, that is, 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 the first support portion 310 and the second support portion 320 from rotating due to a small external force.

[0140] Understandably, the anti-scratch member 318 protrudes from the first support body 311, and the anti-scratch member 318 contacts the first surface 10c, and the anti-scratch member 318 can slide relative to the housing body 10. The anti-scratch member 318 is used to space the first support body 311 from the housing body 10. The anti-scratch member 318 prevents the first support body 311 from directly contacting the first surface 10c. The direct contact between the first support body 311 and the first surface 10c would increase the rotational frictional force of the first support portion 310 and may also cause the first support body 311 or the housing body 10 to be scratched when the first support portion 310 rotates. Therefore, when the first support portion 310 rotates relative to the housing body 10, the anti-scratch member 318 prevents the first support portion 310 from scratching the housing body 10 or the housing body 10 from scratching the first support portion 310.

[0141] In this application, the damping member 316 is located on the outer periphery of the fixed disk 21. The damping member 316 is elastically abutted against the fixed disk 21, and the damping member 316 can rotate 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 is elastically abutted against the outer periphery of the fixed disk 21, and the inner arc surface of the third damping body 3163 is elastically abutted against the outer periphery of the fixed disk 21. By elastically abutting the damping member 316 against the fixed disk 21, it is possible to prevent the first support portion 310 and the second support portion 320 from rotating due to a small external force.

[0142] It should be noted that the contact area between the damping member 316 and the fixed disk 21 or the abutting force between the damping member 316 and the fixed disk 21 can be adjusted to adjust the frictional force that needs to be overcome for the damping member 316 to rotate around the fixed disk 21. The fourth damping body 3164 and the fifth damping body 3165 are spaced apart, so that the damping member 316 has a certain deformation ability, so that the damping member 316 has a certain clamping force on the fixed disk 21 and the clamping force is not too large to prevent the fixed disk 21 from rotating relative to the damping member 316. Moreover, by spacing the second damping body 3162 and the third damping body 3163 from the side walls of the accommodating groove 311c respectively, the second damping body 3162 and the third damping body 3163 have a certain deformation space, so that the damping member 316 is elastically abutted against the fixed disk 21.

[0143] It should be noted that the functions of the flexible member 22 and the damping member 316 are both to prevent the first support portion 310 and the second support portion 320 from rotating due to a small external force. In this application, both the flexible member 22 and the damping member 316 are provided. In other embodiments, only one of the flexible member 22 and the damping member 316 may be provided.

[0144] Please refer to Figure 32 and Figure 33 , Figure 32 is a schematic structural diagram of the slider and the chute when the protective shell is in the vertical screen support state, Figure 33 is a schematic structural diagram of the slider and the chute when the protective shell is in the horizontal screen support state. The slider 312 is arranged in the chute 21a, the slider 312 is slidably connected to the chute 21a, and the slider 312 can slide in the chute 21a, so that the bracket 30 rotates relative to the shell body 10. The radius corresponding to the slider 312 is equal to the radius corresponding to the chute 21a. The slidable angle of the slider 312 in the chute 21a is 270 degrees. That is, the slider 312 slides from the first limit wall a1 to the second limit wall a2 or slides from the second limit wall a2 to the first limit wall a1, and the geometric center point of the slider 312 slides 270 degrees in the chute 21a. Therefore, the radian of the chute 21a is 270 degrees plus the radian of the slider 312.

[0145] Please refer to Figure 6 and Figure 32 , when the protective case is in the vertical screen support state, the second support portion 320 is opened at an angle relative to the first support portion 310. The slider 312 rotates in the chute 21a so that the first support portion 310 and the second support portion 320 rotate relative to the fixing portion 20. The slider 312 rotates in the chute 21a until the slider 312 abuts against the first limiting wall a1. Place the protective case 1 on an object, the direction of the first support force F1 exerted by the object on the second support portion 320 is the X-axis direction, and then the torque T1 of the first support force F1 on the bracket 30 is counterclockwise. The direction of the first abutting force H1 of the first limiting wall a1 on the slider 312 is the X-axis direction, and then the torque T2 of the first abutting force H1 on the bracket 30 is clockwise. The torque T1 of the first support force F1 on the bracket 30 is opposite to the torque T2 of the first abutting force H1 on the bracket 30. 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 abutting force H1 of the first limiting wall a1 on the slider 312 is opposite to the torque T1 of the first support force F1 of the object on the second support portion 320, avoiding the bracket 30 rotating relative to the mobile terminal 2 when the mobile terminal 2 is placed vertically, and enhancing the support of the bracket 30 for the shell body 10.

[0146] It should be noted that the torque mentioned in this application is also the torque. Torque is a vector, which has magnitude and direction, and the unit is N·m. The magnitude of torque is the product of force and the arm of force.

[0147] Please refer to Figure 7 and Figure 33When the protective case is in the horizontal screen support state, the second support portion 320 is opened at an angle relative to the first support portion 310. The slider 312 rotates in the chute 21a so that the first support portion 310 and the second support portion 320 rotate relative to the fixing portion 20. The slider 312 rotates in the chute 21a until the slider 312 abuts against the second limiting wall a2. Place the protective case 1 on an object. The direction of the second support force F2 exerted by the object on the second support portion 320 is the opposite direction of the Y-axis. Furthermore, the torque T3 of the second support force F2 on the bracket 30 is in the clockwise direction. The direction of the second abutting force H2 of the second limiting wall a2 on the slider 312 is the opposite direction of the Y-axis. Furthermore, the torque T4 of the second abutting force H2 on the bracket 30 is in the counterclockwise direction. The torque T3 of the second support force F2 on the bracket 30 is opposite to the torque T4 of the second abutting 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 abutting force H2 of the second limiting wall a2 on the slider 312 is opposite to the torque T3 of the second support force F2 of the object on the second support portion 320, avoiding the bracket 30 rotating relative to the mobile terminal 2 when the mobile terminal 2 is placed vertically, and enhancing the support of the bracket 30 for the shell body 10.

[0148] 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 portion 20 does not have a hollow portion 21d, and the fixing portion 20 does not include an abutting member 26. In the vertical screen support state, the first limiting wall a1 and the first abutting surface 26a of the abutting member 26 can also jointly abut against the slider 312. Therefore, when the slider 312 abuts against the first limiting wall a1, the slider 312 also abuts against the first abutting surface 26a. The abutting member 26 is used to share the acting force of the slider 312 on the first limiting wall a1, avoiding the slider 312 damaging or scratching the first limiting wall a1.

[0149] It should also be noted that in the horizontal screen support state, the second limiting wall a2 can abut against the slider 312 alone, that is, the fixing plate 21 of the fixing portion 20 does not have a hollow portion, and the fixing portion 20 does not include an abutting member 26. In the horizontal screen support state, the second limiting wall a2 and the second abutting surface 26b of the abutting member 26 can also jointly abut against the slider 312. Therefore, when the slider 312 abuts against the second limiting wall a2, the slider 312 also abuts against the second abutting surface 26b. The abutting member 26 is used to share the acting force of the slider 312 on the second limiting wall a2, avoiding the slider 312 damaging or scratching the second limiting wall a2.

[0150] Please refer to Figure 34 , Figure 34 for Figure 2 the bottom view structural schematic diagram of the second support portion shown, Figure 35 for Figure 34Schematic cross-sectional view of the second support portion shown in the VI-VI direction Figure 36 is Figure 34 Schematic structural view of the disassembled second support portion shown. For ease of display Figure 35 the cross-sectional view shown has a certain inclination angle. The second support portion 320 includes a second support body 321, an enclosure 322, a second magnetic member 323, and a packaging member 324. The enclosure 322, the second magnetic member 323, and the packaging member 324 are all disposed on the second support body 321.

[0151] Since the second support portion 320 can rotate relative to the housing body 10 and the second support portion 320 can rotate relative to the first support portion 310, therefore Figures 34 to 36 no schematic of the X-axis direction, Y-axis direction, and Z-axis direction is given in []. Hereinafter, the length direction, width direction, and thickness direction of the second support body 321 are used to describe the second support portion 320, wherein the length direction, width direction, and thickness direction of the second support body 321 are perpendicular to each other in pairs.

[0152] Specifically, as Figure 25 shown, the second support body 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 sequentially disposed 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 body 321 is greater than the height of the third sub-surface 3212c in the thickness direction of the second support body 321, and the height of the third sub-surface 3212c in the thickness direction of the second support body 321 is greater than the height of the second sub-surface 3212b in the thickness direction of the second support body 321. That is, the thickness of the second support body 321 at the first sub-surface 3212a is greater than the thickness of the second support body 321 at the third sub-surface 3212c, and the thickness of the second support body 321 at the third sub-surface 3212c is greater than the thickness of the second support body 321 at the second sub-surface 3212b.

[0153] Please refer to Figure 35 , the second support body 321 includes a second hinge seat 321a. The second hinge seat 321a is one end of the second support body 321 in the length direction, and the second hinge seat 321a is close to 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 disposed along the length direction of the second support portion 320. AsFigure 37 As shown Figure 37 is Figure 34 a schematic structural view of a second hinge seat of the second support body shown. The second hinge seat 321a has a second mounting hole, and the second mounting hole penetrates through the second hinge seat 321a along the width direction of the second support body 321. In this application, the number of the second hinge seats 321a is two, and the two second hinge seats 321a are arranged at intervals along the width direction of the second support body 321.

[0154] Please refer to Figures 34 to 36 , the surrounding body 322 is arranged on the periphery of the second surface 3212 of the second support body 321, and the surrounding body 322 is fixedly connected to the second support body 321. Among them, the surrounding body 322 and the second support body 321 can be integrally formed.

[0155] The second magnetic member 323 is arranged on the second sub-surface 3212b. The encapsulation member 324 is arranged on the surface of the second magnetic member 323 facing away from the second sub-surface 3212b, and the encapsulation member 324 is fixedly connected to the second support body 321. The encapsulation member 324 fixes the second magnetic member 323 to the second support body 321. Among them, the surface of the encapsulation member 324 facing away from the second magnetic member 323 can be flush with the first sub-surface 3212a.

[0156] Please refer to Figure 38 , Figure 38 is a schematic 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 sub-surface 3111c. The positive projection of the first magnetic member 313 in the Z-axis direction coincides with the positive projection of the second magnetic member 323 in the Z-axis direction.

[0157] It should be noted that the magnetic attraction between the first magnetic member 313 and the second magnetic member 323 causes the second support portion 320 to be attached to the first support portion 310. Among them, the first magnetic member 313 is a permanent magnet, and the second magnetic member 323 can be a non-permanent magnet; or, the first magnetic member 313 is a non-permanent magnet, and the second magnetic member 323 is a permanent magnet; or, both the first magnetic member 313 and the second magnetic member 323 are permanent magnets. A permanent magnet is a magnet that can maintain its magnetism for a long time, and a non-permanent magnet is a magnet that can be magnetized under the action of a magnetic field and thus has magnetism. Through the magnetic attraction between the first magnetic member 313 and the second magnetic member 323, the second support portion 320 is prevented from opening relative to the first support portion 310.

[0158] Please refer to Figure 39 , Figure 39It is a schematic structural diagram after the first hinge seat and the second hinge seat are disassembled. Opposite ends of the rotating shaft 314 are respectively arranged in the second mounting holes of two second hinge seats 321a, and two first hinge seats 311a are located between the two second hinge seats 321a. The elastic member 315 is connected to the first support body 311 and the second support body 321 respectively. Among them, when the second support body 321 fits against the first support body 311, the elastic member 315 is elastically compressed, and the elastic member 315 releases elastic potential energy to open the second support body 321 relative to the first support body 311.

[0159] Exemplarily, the elastic member 315 is a torsion spring, and two torsion arms of the torsion spring are respectively connected to the first support body 311 and the second support body 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 spiral torsion spring also has the advantages of stable torsion and long service life.

[0160] 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 the rotating shaft 314 is fixedly connected to the second hinge seat 321a; or, the rotating shaft 314 is fixedly connected to the first hinge seat 311a, and the rotating shaft 314 is rotatably connected to the second hinge seat 321a; or, the rotating shaft 314 is rotatably connected to the first hinge seat 311a, and the rotating shaft 314 is rotatably connected to the second hinge seat 321a. The above three connection relationships between the rotating shaft 314 and the first hinge seat 311a and the second hinge seat 321a can all enable the second support body 321 to rotate relative to the first support body 311, so that the second support body 321 can fit against the first support body 311 or the second support body 321 is opened at an angle relative to the first support body 311.

[0161] It should be noted that when the second support portion 320 is attached to the first support portion 310 under the action of an external force, the elastic member 315 is elastically compressed. When the second support portion 320 is attached to the first support portion 310, the moment of the magnetic force of the first magnetic member 313 on the second magnetic member 323 is greater than the moment 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 an 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, and the elastic member 315 is in a free state, and the moment of the elastic member 315 on the second support portion 320 can also be ignored. The elastic member 315 can cause the second support portion 320 to open relative to the first support portion 310 to a preset angle without manually opening the second support portion 320 to the preset angle. Moreover, after the second support portion 320 is opened relative to the first support portion 310, the elastic member 315 can also prevent the second support portion 320 from rotating arbitrarily relative to the first support portion 310, that is, when the second support portion 320 rotates a certain angle relative to the first support portion 310, the elastic member 315 will be elastically compressed, and the elastic member 315 will cause the angle between the second support portion 320 and the first support portion 310 to return to the preset angle.

[0162] In summary, the terminal component provided by the embodiment of the present application includes a protective case 1 and a mobile terminal 2, and the mobile terminal 2 is disposed within the protective case 1. The protective case 1 includes a case body 10, a fixing portion 20 and a bracket 30. The case body 10 includes a first surface 10c and a second surface 10d, and the first surface 10c and the second surface 10d are disposed opposite to each other along the thickness direction of the case body 10. The fixing portion 20 includes a fixing disk 21, the fixing disk 21 protrudes from the first surface 10c, and the fixing disk 21 is fixedly connected to the case body 10. The fixing disk 21 is provided with a sliding groove 21a, the sliding groove 21a faces away from the first surface 10c, and the sliding groove 21a includes a first limiting wall a1. The bracket 30 includes a first supporting portion 310 and a second supporting portion 320. The first supporting portion 310 includes a first supporting body 311 and a slider 312. The slider 312 is fixedly connected to the first supporting body 311, the slider 312 is slidably connected to the sliding groove 21a, the first supporting portion 310 is disposed on the first surface 10c, and the first supporting body 311 covers the fixing disk 21. The second supporting portion 320 includes a second supporting body 321. One end of the second supporting body 321 is rotatably connected to one end of the first supporting body 311. The second supporting body 321 can be opened at an angle relative to the first supporting body 311 or the second supporting body 321 can be attached to the surface of the first supporting body 311 facing away from the case body 10. Wherein, the slider 312 can slide along the sliding groove 21a, driving the first supporting portion 310 and the second supporting portion 320 to rotate relative to the case body 10. The slider 312 can abut against the first limiting wall a1, and the moment T2 of the first abutting force H1 of the first limiting wall a1 on the slider 312 is opposite to the moment T1 of the first supporting force received by the second supporting portion 320. Therefore, when the mobile terminal 2 is placed vertically on something, the slider 312 abuts against the first limiting wall a1, and the moment T2 of the first abutting force H1 of the first limiting wall a1 on the slider 312 is opposite to the moment T1 of the first supporting force F1 of something on the second supporting portion 320, avoiding the rotation of the bracket 30 relative to the mobile terminal 2 when the mobile terminal 2 is placed vertically, and enhancing the support of the bracket 30 for the mobile terminal 2.
