Description

Technical Field

[0001] This utility model relates to the field of electronic device accessories technology, and in particular to a bracket assembly and accessories for electronic devices. Background Technology

[0002] With the continuous development and upgrading of electronic devices, users' demand for electronic device accessories is also gradually increasing. Electronic device accessories can provide protection and support for electronic devices, such as phone cases with stand components. The main body of the electronic device accessory has a groove, and the stand component of the accessory includes a stand that can rotate relative to the accessory body, allowing the accessory to be in a supported or retracted state. In the retracted state, the stand can be housed within the groove. However, during the process of switching the stand from the retracted state to the supported state, there is a risk that the end of the stand will collide with the side wall of the groove. After repeated collisions, not only will the side wall of the groove be worn down, but the rotating structure of the electronic device accessory will also loosen, causing the stand to lose its effective support. Utility Model Content

[0003] This application provides a bracket assembly and an accessory for electronic devices, which can reduce the risk of the end of the bracket colliding with the side wall of the groove during the process of switching the bracket from a stored state to a supported state.

[0004] The first aspect of this application provides a bracket assembly, which includes a base, a support member, and a connecting member. A first rotating shaft is fixedly mounted on the support member. The connecting member includes a connector, a linkage member, and a second rotating shaft. The connector is fixedly connected to the base. The linkage member is rotatably connected to the connector via the second rotating shaft. The linkage member is also rotatably connected to the first rotating shaft. The support member has a supported state and a retracted state. The connector includes a rotation auxiliary part. During the process of the support member rotating from the retracted state to the supported state, the end of the support member can abut against the rotation auxiliary part so that the first rotating shaft moves away from the base.

[0005] In one specific embodiment, when the support member is in the stored state, the rotation auxiliary part is located between the first rotating shaft and the second rotating shaft along the radial direction of the support member.

[0006] In one specific embodiment, the end of the support member has a first mating surface, and the rotation auxiliary part has a second mating surface. The first mating surface can abut against the second mating surface to move the first rotating shaft away from the base.

[0007] In one specific embodiment, the rotation auxiliary part further has a top surface, and the second mating surface is inclined relative to the top surface and located on the side of the top surface close to the first rotating shaft.

[0008] In one specific embodiment, the rotation auxiliary part further has a connecting surface connected to the second mating surface, the connecting surface facing the end of the support member and located below the second mating surface; The angle between the second mating surface and the horizontal plane is β, and the angle between the connecting surface and the horizontal plane is γ, where γ > β.

[0009] In one specific embodiment, the angle between the second mating surface and the horizontal plane is β, which satisfies: 20°≤β≤50°.

[0010] In one specific embodiment, a wear-resistant component is installed at the end of the support member, and the wear-resistant component forms the first mating surface.

[0011] In one specific embodiment, the wear-resistant component has an mounting end, a connecting end, and a mating end. Two mounting ends spaced apart from each other are connected to one side of the connecting end, and the mating end is connected to the other side of the connecting end. The mating end extends from the connecting end to the side of the support component that wraps around the end of the support component. The mounting end is fixedly connected to the support component, and the connecting end abuts against the end face of the support component along the thickness direction.

[0012] In one specific embodiment, the mating end extends perpendicularly to the connecting end.

[0013] In one specific embodiment, the support member has a first receiving groove, and the two sides of the first receiving groove have rotating grooves. The two ends of the first rotating shaft are respectively located in the two rotating grooves, and a portion of the first rotating shaft is received in the first receiving groove. The mounting end covers the rotating groove to prevent the first rotating shaft from disengaging from the rotating groove.

[0014] In one specific embodiment, there is a clearance space between the two mounting ends and the connecting end, the clearance space being used to avoid the first rotating shaft.

[0015] In one specific embodiment, the wear-resistant component is made of stainless steel.

[0016] In one specific embodiment, the connector further includes two bushing portions, with both ends of the second rotating shaft respectively inserted into the two bushing portions, and a first receiving space for accommodating the second rotating shaft between the two bushing portions; The two bushing portions are located on both sides of the rotation auxiliary portion.

[0017] In one specific embodiment, the connector further includes two connecting portions spaced apart, one connecting portion connecting one end of the bushing portion and the rotation auxiliary portion, and the other connecting portion connecting the other end of the bushing portion and the rotation auxiliary portion.

[0018] In one specific embodiment, the base has a second accommodating space and two mounting slots, the two bushings are respectively located in the two mounting slots and are fixedly connected to the bottom wall of the mounting slots, and the rotation auxiliary part is accommodated in the second accommodating space.

[0019] In one specific embodiment, in the stored state, the line connecting the centerline of the first rotating shaft and the centerline of the second rotating shaft is L1, and in the supported state, the line connecting the centerline of the first rotating shaft and the centerline of the second rotating shaft is L2, and the included angle θ between L2 and L1 satisfies: 20°≤θ≤45°.

[0020] A second aspect of this application provides an accessory for an electronic device, the accessory comprising: The main body is provided with a third receiving groove; A bracket assembly, which is mounted in the third receiving slot; Wherein, the bracket assembly is the bracket assembly described above, and in the stored state, at least a portion of the support member is housed in the third receiving groove, and the rotation center is located within the projection range of the support member toward the bottom wall of the third receiving groove.

[0021] In one possible implementation, the third receiving slot has a first sidewall, and the support member has a first end facing the first sidewall, wherein the first end is always spaced from the first sidewall during the process of the support member switching from the stored state to the supported state.

[0022] In one possible implementation, the accessory of the electronic device further includes a shield located inside the body and covering the projection of the third receiving slot.

[0023] In the solution of this application, during the process of switching the support member from the storage state to the support state, the support member rotates relative to the base. During this process, the end of the support member can cooperate with the rotation auxiliary part, that is, the support member abuts against and overlaps with the rotation auxiliary part. This allows the first axis of rotation of the support member to move away from the base through the cooperation of the support member and the rotation auxiliary part, thereby raising the rotation center of the support member. This reduces the risk of the end of the support member colliding with the side wall of the receiving groove during the rotation of the support member relative to the base, allowing the support member to open to the angle required by the user and meeting the user's usage needs. At the same time, it also prevents repeated collisions between the end and the side wall from affecting the aesthetics of the main body and prevents the connecting components from loosening due to collisions between the end and the side wall, thus making the support member highly reliable.

Detailed Implementation

[0026] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0027] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0028] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0029] It should be understood that the term "and / or" used in this article 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 article generally indicates that the preceding and following related objects have an "or" relationship.

[0030] Electronic devices such as mobile phones and tablets can come with accessories, such as protective cases, to protect them. Often, these accessories also include stand components to support the device in the desired position for easier use.

[0031] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a partial structure of an electronic device component in a specific embodiment of related technologies. For example... Figure 1As shown, the accessory for this electronic device includes an accessory body 10 and a bracket 20. The accessory body 10 has a recess 101 on its back side, and the recess 101 has sidewalls 102. The bracket 20 includes a support member 201 and a base 202. The base 202 is installed within the recess 101. The support member 201 and the base 202 are rotatably connected via a pivot assembly 30, allowing the support member 201 to switch between a supported state and a retracted state. When the support member 201 is in the retracted state, both the support member 201 and the pivot assembly 30 are housed within the recess 101. For a more aesthetically pleasing retracted state, the pivot assembly 30 needs to be hidden, typically concealed inside the support member 201, i.e., the pivot assembly 30 is covered by the support member 201. In order to hide the pivot assembly 30, the end 2011 of the support 201 usually needs to be closer to the side wall 102 of the groove 101, so as to ensure that the pivot assembly 30 can be hidden between the support 201 and the base 202 in the stored state.

[0032] However, when the support member 201 switches from the storage state to the support state, during the rotation of the support member 201 around the rotating shaft assembly 30, when the support member 201 rotates to an angle α with the bottom wall of the groove 101, there is a risk of interference between the end 2011 of the support member 201 and the side wall 102 of the groove 101. Under normal circumstances, this angle α is less than the maximum angle that the support member 201 can open, or less than the optimal support angle of the support member 201, causing the side wall 102 to block the support member 201 from opening to the angle required by the user, affecting the normal use of the bracket 20 and the accessories of the electronic device. Even if the user can apply a large external force to make the end 2011 of the support member 201 interfere with the side wall 102 of the groove 101 so that the support member 201 can continue to rotate, it will cause the end 2011 to collide with the side wall 102. After multiple collisions, the side wall 102 of the groove 101 will be scratched, affecting the aesthetics of the main body 10 of the accessory. Moreover, after multiple collisions, the support member 201 will exert a reaction force on the rotating shaft assembly 30, causing the rotating shaft assembly 30 to loosen and affecting the support reliability of the support member 201 in the supported state.

[0033] This application prevents the support from colliding with the sidewall of the groove during the opening process by changing the position of the rotation center of the support.

[0034] Please refer to Figure 2-6 ,in, Figure 2 A schematic diagram of the structure of an accessory for the electronic device provided in this application in a specific embodiment, wherein the support member is in a stored state; Figure 3 for Figure 2 Explosion diagram, Figure 4 A schematic diagram of the structure of an accessory for the electronic device provided in this application in a specific embodiment, wherein the support member is in a supported state; Figure 5 for Figure 4Another structural diagram from another perspective; Figure 6 This is a schematic diagram of the support assembly provided in this application in a specific embodiment. In the embodiments of this application, as shown... Figure 2 and Figure 4 As shown, the accessories for the electronic device include a main body 1 and a support assembly 2. The main body 1 can specifically be a protective case for the electronic device. For example... Figure 3 In the embodiment shown, the main body 1 can be a roughly rectangular structure, which is used to attach to electronic devices such as mobile phones.

[0035] like Figure 4 and Figure 6 As shown, the support assembly 2 includes a support member 21, a base 22, and a connecting member 23. Figure 3 As shown, a third receiving groove 11 is provided on the back of the main body 1, and the base 22 is installed in the third receiving groove 11 (for example, rotatably installed in the third receiving groove 11). The support member 21 and the base 22 are rotatably connected by a connecting member 23, so that the support member 21 has a stored state and a supported state. Figure 2 In the storage state shown, at least a portion of the structure of the support member 21 is housed within the third receiving groove 11, and the center of rotation is located within the projection range of the support member 21 toward the bottom wall 111.

[0036] In such Figure 4 and Figure 6 In the supported state shown, the support member 21 can be opened relative to the base 22, thereby supporting the main body 1. The support member 21 and the base 22 can also be rotatably connected in other ways, as long as the support member 21 can rotate freely relative to the main body 1. During the rotation of the support member 21 relative to the base 22, the center of rotation of the support member 21 can move.

[0037] In some embodiments, the support member 21 of the bracket assembly 2 can be an annular structure, and the third receiving groove 11 can also be an annular structure. The annular third receiving groove 11 has a boss 113 inside. When the bracket assembly 2 is in the storage state, the support member 21 is sleeved on the outside of the boss 113.

[0038] In such Figure 5 In the illustrated embodiment, the main body 1 may also include a shielding member 12, which is located on the inner side of the main body 1, that is, on the side of the main body 1 away from the bracket assembly 2, so that the projection of the shielding member 12 covers the projection of the third receiving groove 11, thus playing a role in concealing the unsightly parts. Even if the main body 1 is made of transparent material, the user will not be able to see the third receiving groove 11 and the bracket assembly 2 from the inside of the main body 1, thereby improving the sophistication of the electronic device accessories.

[0039] Specifically, the shielding member 12 can be a shielding film, that is, a thin film that does not protrude significantly from the inner wall of the main body 1, thereby further improving the appearance and refinement of the electronic device accessories.

[0040] The positions where the above-described support components and the main body mate can be simplified as follows: Figure 7 . Figure 7 In the diagram, the dashed lines represent a structural schematic of the support member 21 and the connecting member 23 in the related technology. Figure 7 The dashed line indicates that when the support member 21 rotates to an angle α with the bottom wall 111 of the third receiving groove 11, the end of the support member 21 collides with the side wall 102 of the third receiving groove 11. Additionally, Figure 7 It is also shown that, compared with the related technology, during the rotation of the support member 21 in the embodiment of this application, the rotation center A of the support member 21 is raised (that is, compared with the related technology, the distance between the rotation center A and the bottom wall 111 of the third receiving groove 11 is larger in the embodiment of this application), thereby preventing the support member 21 from colliding with the side wall 102 of the third receiving groove 11 during the rotation. Therefore, in this embodiment, during the process of switching the support member 21 from the storage state to the support state, the rotation center A of the support member 21 moves in a direction away from the bottom wall 111 of the third receiving groove 11, causing the first end 211 of the support member 21 to move away from the bottom wall 111. This reduces the risk of collision between the first end 211 and the side wall 102 of the third receiving groove 11 during the rotation of the support member 21 from the storage state to the support state, allowing the support member 21 to open to the angle required by the user and meet the user's usage needs. At the same time, it can also prevent the first end 211 from colliding with the side wall 102 multiple times, thus affecting the aesthetics of the main body 1, and prevent the connecting member 23 from loosening due to the collision between the first end 211 and the side wall 102, making the support member 21 have high support reliability.

[0041] The following section describes in detail the specific structure that enables the rotation center of the support to move away from the bottom wall of the receiving groove.

[0042] Specifically, the support member 21 is provided with a mating part, and the base 22 is provided with a rotation auxiliary part. During the process of switching the support member 21 from the storage state to the support state, the support member 21 rotates relative to the base 22. During this process, the mating part can cooperate with the rotation auxiliary part, that is, the mating part and the rotation auxiliary part contact and overlap along the thickness direction of the bracket assembly. Thus, the rotation center A of the support member 21 can be driven to move in the direction away from the base 22 through the cooperation of the mating part and the rotation auxiliary part, thereby raising the rotation center A of the support member 21 and reducing the risk of the first end 211 of the support member 21 colliding with the side wall 102 of the third receiving groove 11 during the rotation of the support member 21 relative to the base 22.

[0043] In a specific embodiment, when the support member 21 is in the retracted state, the mating part and the rotation auxiliary part can be disengaged from each other, that is, the mating part and the rotation auxiliary part are staggered from each other along the thickness direction of the bracket assembly.

[0044] In some embodiments, the mating part can be a structure that protrudes toward the base 22 along the thickness direction of the support assembly, and / or the rotation assist part can be a structure that protrudes toward the support member 21 along the thickness direction of the support assembly. When the support member 21 switches from the stored state to the supported state, at least one of the mating parts with protruding structures overlaps with the rotation assist part along the thickness direction of the support assembly, thereby raising the rotation center of the support member 21.

[0045] In other embodiments, the support assembly 2 may not include a base, with one end of the connecting member 23 connected to the support member 21 and the other end connected to the main body 1. When the support assembly 2 does not include a base, the second mating part may be disposed in the third receiving groove 11 of the main body 1. The following description uses an embodiment in which the support assembly 2 includes the support member 21, the base 22, and the connecting member 23 as an example. The specific structure of the connecting member is described in detail below.

[0046] Please continue to refer to this. Figure 8-12 , Figure 8 This is a schematic diagram of the structure of the connecting member provided in this application in a specific embodiment, wherein the connecting member is in a supporting state; Figure 9 This is a top view of the bracket assembly provided in this application, wherein the bracket assembly is in a stowed state; Figure 10 for Figure 9 A partial view of the AA-direction sectional view; Figure 11 This is a structural schematic diagram of the support member in some embodiments; Figure 12 for Figure 11 A magnified view of part I.

[0047] like Figure 8 and Figure 10 As shown, the connecting member 23 includes a connector 235 and a linkage 231. The connector 235 is fixed to the base 22, and the support member 21 is rotatably connected to the connector 235 through the linkage 231, so that the support member 21 can rotate relative to the base 22.

[0048] One end of the linkage 231 is rotatably connected to the support 21 via a first rotating shaft 232. The other end of the linkage 231 is rotatably connected to the connector 235 via a second rotating shaft 233, thereby indirectly connecting the linkage 231 and the base 22 via the connector 235. When the support 21 switches from a stored state to a supported state, the linkage 231 can rotate around the first rotating shaft 232 in a direction away from the base 22, causing the angle between the linkage 231 and the base 22 to gradually increase.

[0049] In other embodiments, the linkage 231 and the support 21 can also be rotatably connected by another connector. That is, the connecting member 23 can also include a second connector, which is fixedly connected to the support 21, and the linkage 231 and the second connector are connected by a first rotating shaft 232, so that the linkage 231 and the support 21 are indirectly rotatably connected by the second connector.

[0050] Specifically, such as Figure 8 and Figure 10 As shown, the two ends of the linkage 231 have a first socket 2311 and a second socket 2312, respectively. The first rotating shaft 232 passes through the first socket 2311 and through the rotating structure on the support member 21, and the first rotating shaft 232 can rotate relative to the support member 21.

[0051] Similarly, such as Figure 8 and Figure 10 As shown, the connector 235 includes a bushing portion 2351, a second rotating shaft 233 passing through the bushing portion 2351 and the second sleeve portion 2312, and the second rotating shaft 233 is rotatable relative to the bushing portion 2351.

[0052] Please also refer to point 9. When the support member 21 is in the retracted state, it overlaps the base 22. When the support member 21 switches from the retracted state to the supported state, the center of the first pivot 232 at the connection between the support member 21 and the linkage member 231 is the aforementioned rotation center A. The support member 21 can rotate around this first pivot 232 in a direction away from the base 22 to increase the angle between the support member 21 and the base 22. The second pivot 233 at the connection between the linkage member 231 and the base 22 is another rotation center of the linkage member 231. As the support member 21 rotates, the linkage member 231 can rotate around this second pivot 233 in a direction away from the bottom wall 111 and the first side wall 112 of the third receiving groove 11. That is, the angle between the linkage member 231 and the base 22 gradually increases, thereby driving the support member 21 to move away from the bottom wall 111 and the first side wall 112.

[0053] Combination Figure 7 It can be seen that during the process of the support member 21 rotating from the storage state to the support state, the linkage member 231 raises the position of the support member 21 in the thickness direction of the bracket assembly 2, causing the rotation center A of the linkage member 231 to move upward and to the right. Figure 7(From the perspective shown) This reduces the risk that the first end 211 of the support member 21 will interfere with the first side wall 112 of the third receiving groove 11 during the process of switching the support assembly 2 from the storage state to the support state, which may cause the support member 21 to be unable to continue rotating. This makes the rotation of the support member 21 no longer restricted, increases the rotation angle of the support member 21, and enables the support assembly 2 to meet the user's needs and improve the user experience.

[0054] In this context, the first sidewall 112 of the third receiving groove 11 represents the sidewall of the third receiving groove 11 on the side of the rotation center A. When the third receiving groove 11 is circular or annular, the first sidewall 112 can be a portion of the sidewall of the third receiving groove 11 within a preset central angle range, such as -20° to 20°, or a portion within other angle ranges. This application does not limit the central angle range of the first sidewall 112, as long as it is a sidewall close to the rotation center A. Furthermore, when the third receiving groove 11 is circular or annular, it also includes a second sidewall 114 opposite to the first sidewall 112.

[0055] Please continue to refer to this. Figure 7 When the support member 21 is in the retracted state, the line connecting the centerline of the first rotating shaft 232 (rotation center A) and the centerline of the second rotating shaft 233 is L1. When the support member 21 is in the supported state, the line connecting the centerline of the first rotating shaft 232 and the centerline of the second rotating shaft 233 is L2. L1 and L2 are as follows... Figure 7 As shown by the medium-thick dashed line. The angle between L1 and L2 is θ, where 20°≤θ≤45°. For example, θ can be 20°, 22°, 23°, 30°, 33°, 35°, 40°, 45°, etc.

[0056] In this embodiment, the included angle θ between L1 and L2 can represent the angle at which the support member 21 is raised from the stored state to the folded state. When 20°≤θ≤45°, the angle at which the rotation center A is raised is appropriate. This can prevent the support member 21 from interfering with the first end 211 of the support member 21 and the first side wall 112 of the third receiving groove 11, thus preventing the support member 21 from continuing to rotate.

[0057] in addition, Figure 10 and Figure 12 In the embodiment shown, the connector 235 is provided with a rotation assist portion 236, and the support member 21 is provided with a mating portion 214. Please continue to refer to... Figure 13 , Figure 13 for Figure 12 A schematic diagram of the connecting component. (Combined) Figure 12 and Figure 13The rotation auxiliary part 236 protrudes along the thickness direction of the bracket assembly, that is, the rotation auxiliary part 236 protrudes towards the support member 21 along the thickness direction. During the process of switching the support member 21 from the stored state to the supported state, the rotation auxiliary part 236, with its protruding structure, raises both the mating part 214 and the support member 21, thereby raising the support member 21. Furthermore, during the rotation of the support member 21 relative to the connecting member 235 under the action of the linkage 231, the rotation auxiliary part 236 can also support the support member 21 through the mating part 214, thereby reducing the stress on the linkage 231 and improving its service life.

[0058] Among them, such as Figure 10 and Figure 12 As shown, along the radial direction of the bracket assembly, the rotation auxiliary part 236 is located between the first rotating shaft 232 and the second rotating shaft 233.

[0059] The specific structure of the connector is described in detail below.

[0060] Please continue to refer to this. Figure 12 and Figure 13 The rotation auxiliary part 236 also has a second mating surface 2361. When the support member 21 switches from the storage state to the support state, the first mating surface of the mating part 214 and the second mating surface 2361 of the rotation auxiliary part 236 can make surface contact, driving the support member 21 to move in the direction away from the bottom wall of the third receiving groove 11, reducing the risk of the first end 211 colliding with the first side wall 112 of the receiving groove during the rotation of the support member 21 relative to the base 22.

[0061] Specifically, such as Figure 13 As shown, the rotation auxiliary part 236 also has a top surface 2363 and a connecting surface 2362, and a second mating surface 2361 is connected between the connecting surface 2362 and the top surface 2363.

[0062] The top surface 2363 can be a plane parallel to the horizontal plane, or the top surface 2361 can be an inclined plane with a small angle to the horizontal plane.

[0063] Please continue to refer to this. Figure 14 and Figure 15 , Figure 14 for Figure 13 Top view; Figure 15 for Figure 14The CC-direction sectional view. In some specific embodiments, the second mating surface 2361 has an angle β with the plane of the base (or the plane where the main body is located, or the horizontal plane). Wherein, 0°≤β<90°, for example, β can be 0°, 10°, 30°, 40°, 45°, 50°, 60°, 70°, 80°, etc. That is, the second mating surface 2361 can be parallel to the plane where the base is located, or the second mating surface 2361 can be an inclined surface, so that when the first mating surface and the second mating surface 2361 are in contact, the support member 21 can be restricted to this position, further improving the support reliability of the support member 21.

[0064] In addition, when the second mating surface 2361 is inclined, the support member 21 can open at a suitable angle to meet the support requirements of the electronic equipment.

[0065] In some embodiments, the connecting surface 2362 is an inclined surface, that is, the connecting surface 2361 has an angle γ with the plane of the base (or the plane where the main body is located). γ > β, so that the slope of the second mating surface 2361 is gentler and the slope of the connecting surface 2361 is more angular, thereby reducing the size required for the rotation auxiliary part 236 and facilitating the miniaturization of the bracket assembly.

[0066] In some specific embodiments, 20°≤β≤50°, for example, β can be 20°, 22°, 25°, 30°, 32°, 35°, 40°, 45°, 50°, etc. Within this range, the second mating surface 2361 will not obstruct the movement of the support member 21, preventing the support member 21 from opening to the required angle, and the second mating surface 2361 can also contact the first mating surface of the mating part 214 when the support member 21 rotates to the opening angle.

[0067] In other embodiments, the connecting surface 2362 of the rotation auxiliary part 236 may also be one or more of concave and convex surfaces. This application does not limit the type of the connecting surface 2362.

[0068] In some embodiments, such as Figure 12 As shown, at least one of the support member 21 and the rotation auxiliary part 236 is provided with a wear-resistant part 216. The mating part 214 of the support member 21 and the rotation auxiliary part 236 are in contact through the wear-resistant part 216. That is, during the rotation of the support member 21, the wear-resistant part 216 can reduce the wear of the mating part 214 and / or the rotation auxiliary part 236, thereby improving the safety, integrity and service life of the support member 21 and / or the rotation auxiliary part 236.

[0069] The wear-resistant part 216 can be made of stainless steel, and the stainless steel wear-resistant part 216 has good wear resistance.

[0070] Specifically, such as Figure 12In the illustrated embodiment, the wear-resistant part 216 is mounted on the mating portion 214 of the support member 21, and the wear-resistant part 216 forms the first mating surface described above. At this time, when the support member 21 switches between a retracted state and a supported state, the wear-resistant part 216 can prevent the support member 21 from being worn.

[0071] In other embodiments, the rotation assist 236 may also be provided with a wear-resistant component to prevent the rotation assist 236 from being worn.

[0072] Please continue to refer to this. Figures 16-20 ,in, Figure 16 This is a structural schematic diagram of the support member in some embodiments; Figure 17 for Figure 16 A magnified view of part I; Figure 18 This is a structural schematic diagram of the support member and the first rotating shaft in some embodiments; Figure 19 for Figure 18 A magnified view of part II; Figure 20 for Figure 19 A schematic diagram of the structure of a medium-strength wear-resistant component. (See attached diagram.) Figure 17 and Figure 20 As shown, the wear-resistant part 216 has a mounting end 2161, a connecting end 2164, and a mating end 2162. The mounting end 2161 is fixedly connected to the support member 21. In some embodiments, the support member 21 may be provided with a connecting post 215, and the mounting end 2161 is fixed to the support member 21 through the connecting post 215, that is, the wear-resistant part 216 is riveted to the support member 21. In other embodiments, the mounting end 2161 may also be fixedly mounted to the support member 21 in other ways. This application does not limit the fixed connection method between the mounting end 2161 and the support member 21.

[0073] The connecting end 2164 connects to two spaced mounting ends 2161. When the wear-resistant part 216 is installed at the end of the support 21, the connecting end 2164 abuts against the end face of the support 21 along the thickness direction.

[0074] The mating end 2162 and the mounting end 2161 are connected to both sides of the connecting end 2164, and the mating end 2164 is bent relative to the connecting end 2164 along the thickness direction of the support member 21, that is, the mating end 2162 is bent and extends to the outer side of the outer peripheral wall of the support member 21. The wear-resistant part 216 wraps around the end of the support member 21, thereby protecting the support member 21. Therefore, the wear-resistant part 216 forms the mating part described above.

[0075] In one specific embodiment, the mating end 2162 is perpendicular to the connecting end 2164.

[0076] like Figure 17 and Figure 19As shown, the support member 21 has a rotating groove 212, through which the first rotating shaft 232 passes. Between the two rotating grooves 212 is a first receiving groove 213, which is used to receive the first rotating shaft 232, thereby reducing the size of the support assembly in the thickness direction.

[0077] After the wear-resistant part 216 is installed on the support 21, the mounting end 2161 can cover a part of the rotating groove 212, thereby restricting the first rotating shaft 232 from disengaging from the rotating groove 212 through the mounting end 2161. That is, the rotating structure of the support 21 described above is formed by the mounting end 2161 of the wear-resistant part 216 and the rotating groove 212, so that the support 21 does not need to be provided with a bushing part to fit the first rotating shaft 232, simplifying the structure of the support 21 and reducing the thickness of the support 21.

[0078] Specifically, such as Figure 20 As shown, the wear-resistant part 216 has two mounting ends 2161, both of which are fixed on the support member 21, and there is a clearance space 2163 between the two mounting ends 2161. The clearance space 2163 is used to avoid the first rotating shaft 232 and the linkage member 231, so as to prevent the wear-resistant part 216 from interfering with the first rotating shaft 232 and the linkage member 231.

[0079] Please refer to this again. Figure 13 The connector 235 includes two bushing portions 2351 and two connecting portions 237. The two bushing portions 2351 are used to fit the second rotating shaft, and a first receiving space 2352 for accommodating the second rotating shaft is provided between the two bushing portions 2351. One of the two connecting portions 237 connects one bushing portion 2351 and one end of the rotation auxiliary portion 236 along the length direction, and the other connecting portion 237 connects the other bushing portion 2351 and the other end of the rotation auxiliary portion 236 along the length direction.

[0080] Please continue to refer to this. Figure 21 and Figure 22 ,in, Figure 21 This is a structural diagram of the base in one specific embodiment. Figure 22 This is a schematic diagram of the connector mounted on the base. The base 22 has a second receiving space 222 and two mounting slots 223 located on either side of the second receiving space 222. The two bushing portions 2351 of the connector 235 are respectively mounted in the two mounting slots 223, and the two bushing portions 2351 are fixedly connected to the bottom wall of the mounting slots 223. The second receiving space 222 is used to accommodate the connecting portion 237 and the rotation auxiliary portion 236 of the connector 235, thereby reducing the thickness of the base 22 occupied by the connector 235.

[0081] Please continue to refer to this. Figure 23-25 , Figure 23This is a schematic diagram of the structure of the support assembly provided in this application in another specific embodiment; Figure 24 for Figure 23 Schematic diagram of the structure of the mating parts; Figure 25 for Figure 23 A schematic diagram of a local structure. (For example...) Figure 23 and Figure 25 As shown, the bracket assembly may also include an elastic module 3, which can be installed on the boss 113 of the main body, thereby making reasonable use of the space of the boss 113. The elastic module 3 is arranged opposite to the handle groove of the support member 21.

[0082] like Figure 24 As shown, the base 22 includes a mating part 221, which is sleeved on the boss 113. The mating part 221 is provided with a mating groove 2211. When the base 22 rotates in the third receiving groove 11 of the main body 1, the mating groove 2211 rotates with the base 22 relative to the elastic module 3, thereby limiting the elastic module 3 to engage with different mating grooves 2211.

[0083] The aforementioned mating groove 2211 can be provided on the inner wall of the mating part 221, so that the mating part 221 with the mating groove 2211 can be machined separately without having to provide a separate mating groove on the body 221.

[0084] In some embodiments, such as Figure 25 As shown, the elastic module 3 may include an elastic element 32 and an abutment portion 33. One end of the elastic element 32 is connected to the abutment portion 33, and the other end is connected to the outer shell 31 of the elastic module 3. When the base rotates, under the action of external force, the side wall of the first mating groove 2111 presses against the elastic element 32. When the abutment portion 33 is aligned with the mating groove 2211, under the action of the rebound force of the elastic element 32, the abutment portion 33 is driven to engage with the mating groove 2211 in a limited fit. This restricts the rotation of the mating part 221 relative to the elastic module 3, confining the base to this position and improving the support reliability of the bracket assembly at this position. At this position, the base can continue to rotate only when the user applies a larger external force.

[0085] In addition, the mating part 221 can also be a structure made of hard materials such as metal or alloy. When the mating part 221 rotates with the base, the contact part 33 makes a clicking sound when it comes into contact with the mating groove 2211 of the mating part 221, thus improving the user experience.

Any changes or substitutions within the technical scope disclosed in the embodiments of this application should be covered within the protection scope of the embodiments of this application. Therefore, the protection scope of the embodiments of this application should be determined by the protection scope of the claims.
