Description

Technical Field

[0001] This application relates to the technical field of brackets, and in particular to a bracket structure. Background Art

[0002] Currently, digital product components, such as protective cases, power banks, and wireless chargers, are deeply associated with electronic products such as mobile phones and tablets. In order to meet the need to free hands, the need to use the above-mentioned various devices in combination with a back clip bracket has emerged accordingly.

[0003] There are various design schemes of existing back clip brackets on the market. However, most back clip brackets cannot pop open automatically, and users need to manually adjust the back clip bracket to open and store it, which increases the user's operation steps. Moreover, some back clip brackets are tightly clamped, which will further increase the operation difficulty. Summary of the Utility Model

[0004] An embodiment of this application provides a bracket structure that can achieve an automatic pop-up function, simplifies user operations, and is convenient to use.

[0005] In a first aspect, an embodiment of this application provides a bracket structure having a retracted position and a deployed position. The bracket structure includes: a fixed frame; a movable frame rotatably connected to the fixed frame about a first axis to enable the bracket structure to switch between the retracted position and the deployed position. In the retracted position, the movable frame and the fixed frame are stacked, and in the deployed position, the movable frame and the fixed frame are disposed at an angle; a locking member having a locked position and an unlocked position. In the locked position, the bracket structure is in the retracted position and the locking member connects the fixed frame and the movable frame. In the unlocked position, the locking member releases the connection with the fixed frame and / or the movable frame; and a first pushing member including a fixed plate and a movable plate. The fixed plate is fixed relative to the fixed frame, and the movable plate is fixed relative to the movable frame. One of the fixed plate and the movable plate includes an elastic portion, and the other includes a cooperating portion. In the retracted position, the elastic portion is located outside the cooperating portion and is in a deformed state in the direction of the first axis. When the locking member is in the unlocked position, the elastic portion moves from the deformed state towards the restored state, causing the movable frame to rotate relative to the fixed frame about the first axis, such that at least a part of the elastic portion is located within the cooperating portion, and the bracket structure is in the deployed position.

[0006] The beneficial effects of the present application are as follows: When the user needs to use the bracket structure, by triggering the locking member, the locking member is switched from the locking position to the unlocking position. Under the action of the first pushing member, the elastic portion in the retracted position has a moving tendency to recover from the deformed state to the restored state. Under the action of this tendency, the elastic portion can drive the movable plate to rotate a certain angle along the first axis, so that the elastic portion and the matching portion cooperate and return to the restored state, thereby realizing the automatic switching of the bracket structure from the retracted position to the deployed position without the user manually operating the rotation of the movable frame. And the bracket structure in the deployed position is fixed by the cooperation of the elastic portion and the matching portion. On the one hand, the bracket structure can be locked by the elastic force, and on the other hand, the bracket structure can also be locked by the cooperation of the elastic portion and the matching portion, so that the bracket structure has strong supporting performance.

[0026] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] Currently, digital product components, such as protective shells, power banks, and wireless chargers, are deeply associated with the use of electronic products such as mobile phones and tablets. In order to meet the need to free hands, the use requirements of the above various devices combined with back clip brackets have emerged accordingly.

[0028] There are various existing design schemes for back clip brackets on the market. However, most back clip brackets cannot pop open automatically, and users need to manually adjust the back clip brackets to open and store them, which increases the user's operation steps. Moreover, some back clip brackets are tightly clamped, which will further increase the operation difficulty.

[0029] Please refer toFigures 1 to 3 To solve the above technical problems, the present application proposes a bracket structure 1000, which is applied to the housing of an electronic device. The bracket structure 1000 has a retracted position and an extended position. The bracket structure 1000 includes: a fixed frame 1, a movable frame 2, a locking member 3, and a first pushing member 4.

[0030] Among them, the movable frame 2 is rotatably connected to the fixed frame 1 about a first axis X to enable the bracket structure 1000 to switch between the retracted position and the extended position. In the retracted position, the movable frame 2 and the fixed frame 1 are stacked, and in the extended position, the movable frame 2 and the fixed frame 1 are arranged at an angle. In the embodiments of the present application, the movable frame 2 and the fixed frame 1 can rotate relative to each other along the first axis X. It can be a single rotation of the movable frame 2 or the fixed frame 1, or a simultaneous relative rotation of the movable frame 2 and the fixed frame 1. The present application does not limit this here, as long as they can rotate relative to each other to achieve the position switching of the bracket structure 1000. In the retracted position, the movable frame 2 and the fixed frame 1 are stacked, which is beneficial to reducing the thickness of the bracket structure 1000. In the extended position, the movable frame 2 and the fixed frame 1 are arranged at an angle, which can achieve the supporting effect of the bracket structure 1000.

[0031] The locking member 3 has a locking position and an unlocking position. In the locking position, the bracket structure 1000 is in the retracted position and the locking member 3 connects the fixed frame 1 and the movable frame 2. In the unlocking position, the locking member 3 releases the connection with the fixed frame 1 and / or the movable frame 2. It can be understood that in the locking position, the locking member 3 connects the fixed frame 1 and the movable frame 2 to prevent the relative movement between the fixed frame 1 and the movable frame 2, thereby ensuring that the fixed member and the movable member remain in the retracted position and will not easily pop out. After the user operates the locking member 3 to be in the unlocking position, the locking member 3 can release the movable frame 2, thereby releasing the locked state between the fixed frame 1 and the movable frame 2, facilitating the relative rotation of the movable frame 2 relative to the fixed frame 1 under the action of the first pushing member 4, and enabling the bracket structure 1000 to reach the extended state, realizing automatic expansion.

[0032] Specifically, the working principle of the first pushing member 4 is as follows: The first pushing member 4 includes a fixed plate 41 and a movable plate 42. The fixed plate 41 is fixed relative to the fixed frame 1, and the movable plate 42 is fixed relative to the movable frame 2. One of the fixed plate 41 and the movable plate 42 includes an elastic part 411, and the other includes a matching part 422b. In the retracted position, the elastic part 411 is located outside the matching part 422b and the elastic part 411 is in a deformed state in the direction of the first axis X. When the locking member 3 is in the unlocking position, the elastic part 411 moves from the deformed state towards the restored state, causing the movable frame 2 to rotate relative to the fixed frame 1 about the first axis X, so that at least part of the elastic part 411 is located within the matching part 422b, realizing that the bracket structure 1000 is in the extended position.

[0033] It can be understood that the mating part 422b is a concave part, and the mating part 422b has an installation space for accommodating the insertion of the elastic part 411, so as to cooperate with the movement of the elastic part 411.

[0034] In the first pushing member 4, one of the fixed plate 41 and the movable plate 42 includes an elastic part 411, and the other includes a mating part 422b. With such a setting, there are at least the following two situations. One is that the fixed plate 41 includes the elastic part 411 and the movable plate 42 includes the mating part 422b; the second is that the fixed plate 41 includes the mating part 422b and the movable plate 42 includes the elastic part 411. The present application does not limit the above situations here, as long as the elastic part 411 and the mating part 422b are respectively located on different structures and cooperate with each other, the effect can be achieved.

[0035] It can be understood that when the user needs to use the bracket structure 1000, by triggering the locking member 3, the locking member 3 is switched from the locking position to the unlocking position. Under the action of the first pushing member 4, the elastic part 411 in the retracted position has a moving tendency to recover from the deformed state to the restored state. Under the action of this tendency, the elastic part 411 can drive the movable plate 42 to rotate a certain angle along the first axis X, so that the elastic part 411 moves into the mating part 422b and returns to the restored state, thereby realizing the automatic switching of the bracket structure 1000 from the retracted position to the deployed position without the user manually operating the rotation of the movable frame 2. And the bracket structure 1000 in the deployed position is fixed by the cooperation of the elastic part 411 and the mating part 422b. On the one hand, the bracket structure 1000 can be locked by the elastic force, and on the other hand, the bracket structure 1000 can also be locked by the cooperation of the elastic part 411 and the mating part 422b, so that the bracket structure 1000 has strong supporting performance.

[0036] Please refer to Figure 3 and Figure 4 As shown in, the first pushing member 4 includes a plurality of elastic parts 411 and a plurality of mating parts 422b. The plurality of elastic parts 411 are arranged at intervals along the first axis X, and the plurality of elastic parts 411 are arranged in one-to-one correspondence with the plurality of mating parts 422b. In some embodiments, in order to ensure the effectiveness of the action of the first pushing member 4, the number of the elastic part 411 and the corresponding mating part 422b is plural, which can be two, three or even more. The present application does not limit this here. Each elastic part 411 is distributed at intervals along the first axis X, that is, the elastic parts 411 are respectively distributed at different positions of the fixed plate 41 or the movable plate 42 along the first axis X, so as to disperse the stress, which can avoid the damage of a single elastic part 411 due to excessive force, and the cooperation of each elastic part 411 and the mating part 422b can also ensure the uniformity of the force between the fixed frame 1 and the movable frame 2, and ensure the smooth rotation between the fixed frame 1 and the movable frame 2.

[0037] Furthermore, since the elastic part 411 and the multiple engaging parts 422b correspond to each other, a multi-point contact fit is formed, improving the reliability of the bracket structure 1000. With such an arrangement, even if the elastic part 411 and the engaging part 422b at a certain part fail, the other elastic parts 411 and engaging parts 422b can still function properly to ensure the normal use of the bracket structure 1000.

[0038] In some embodiments of the present application, the fixed plate 41 includes an elastic part 411, and the movable plate 42 includes an engaging part 422b. That is, the fixed plate 41 is provided with an elastic part 411, the movable plate 42 is provided with an engaging part 422b, and the cooperation between the elastic part 411 and the engaging part 422b drives the relative rotation between the fixed plate 41 and the movable plate 42, thereby realizing the function of the automatic pop-up of the bracket structure 1000 from the retracted position to the deployed position.

[0039] Please refer to Figure 3 , further, the fixed plate 41 further includes a first fixing part 412, the first fixing part 412 is fixedly connected to the fixed frame 1, the elastic part 411 includes a connecting end 4111 and a free end 4112, the connecting end 4111 is connected to the first fixing part 412, the free end 4112 extends towards the movable plate 42 and has a convex part 4112c. When the locking member 3 is in the unlocking position, the elastic part 411 moves from the deformed state towards the restored state, causing the movable frame 2 to rotate relative to the fixed frame 1 about the first axis X, so that the convex part 4112c is located within the engaging part 422b, realizing that the bracket structure 1000 is in the deployed position.

[0040] Specifically, the first fixing part 412 is fixedly connected to the fixed frame 1. In some embodiments, it is usually fixed to the fixed frame 1 by means of a screw connection, welding, gluing or other fixing methods to ensure that the two can move simultaneously and will not loosen or displace during use. The above fixing methods are not limited in this application as long as the fixing effect can be satisfied.

[0041] The elastic part 411 has a connecting end 4111 and a free end 4112 in opposite directions. The connecting end 4111 is connected to the first fixing part 412, and the free end 4112 is arranged close to the movable plate 42. It can be understood that the first fixing part 412 can carry the elastic part 411 to ensure the stability of the elastic part 411 on the fixing plate 41. The convex part 4112c is a protrusion on the free end 4112 and can be used to cooperate with the cooperating part 422b on the movable plate 42. In the retracted position, the elastic part 411 is in a deformed state in the first axis X direction. At this time, the convex part 4112c is located outside the cooperating part 422b, and the locking member 3 is switched to the unlocking position, thereby releasing the locked state between the movable frame 2 and the fixed frame 1. The elastic part 411 starts to move from the deformed state to the restored state. The thrust generated during the restoration process of the elastic part 411 further pushes the movable frame 2 to rotate. As the movable frame 2 rotates, the convex part 4112c gradually enters the cooperating part 422b on the movable plate 42. When the convex part 4112c completely or partially enters the cooperating part 422b, the movable frame 2 and the fixed frame 1 form a certain angle, and the bracket structure 1000 is in the deployed position.

[0042] With such a setting, the bracket structure 1000 can be automatically switched from the retracted position to the deployed position, and the cooperation between the convex part 4112c and the cooperating part 422b provides a better locking effect to ensure the stability of the bracket structure 1000 in the deployed position.

[0043] In addition, in some embodiments of the present application, the bracket structure 1000 further includes a rotating shaft 5. The rotating shaft 5 extends along the first axis X. Both the fixing plate 41 and the movable plate 42 are sleeved on the rotating shaft 5 and at least one of them can rotate relative to the rotating shaft 5 to realize the rotatable connection between the movable frame 2 and the fixed frame 1 around the first axis X. The rotating shaft 5 provides a rotation fulcrum for the fixing plate 41 and the movable plate 42, and both the fixing plate 41 and the movable plate 42 are sleeved on the rotating shaft 5. The rotating shaft 5 acts as a support and connecting member between the fixing plate 41 and the movable plate 42, enabling the fixing plate 41 and the movable plate 42 to be correspondingly installed. And one of the fixing plate 41 and the movable plate 42, or both the fixing plate 41 and the movable plate 42 can rotate around the rotating shaft 5 to realize the relative rotation between the fixing plate 41 and the movable plate 42, further ensuring the automatic pop-up function of the bracket structure 1000.

[0044] Further, since the fixing plate 41 is connected to the rotating shaft 5, the fixing plate 41 includes an elastic portion 411. The free end 4112 of the elastic portion 411 is sleeved on the rotating shaft 5. The free end 4112 has a first end wall 4112a and a second end wall 4112b that are opposite to each other in the first axis X direction. Along the first axis X direction, the first end wall 4112a is closer to the movable plate 42 than the second end wall 4112b. The first end wall 4112a bulges along the first axis X and towards the movable plate 42 to form a convex portion 4112c. It can be understood that in the embodiment of the present application, the elastic portion 411 includes an elastic arm. The elastic arm is connected to the cylindrical portion of the rotating shaft 5 to form the free end 4112. The elastic arm has a deformed state and a restored state in the first axis X direction. The cylindrical portion is sleeved and installed on the rotating shaft 5. Moving along the first axis X of the rotating shaft 5 towards a position deviating from the center forms a deformed state, while moving towards the center position forms a restored state. The convex portion 4112c is formed on the first end wall 4112a of the free end 4112 close to the movable plate 42, which is convenient for cooperating with the engaging portion 422b of the movable plate 42 and facilitating the automatic ejection of the bracket structure 1000.

[0045] Please refer to Figure 3 and Figure 4 , the movable plate 42 includes a second fixing portion 421 and a sleeve 422. The second fixing portion 421 is fixed relative to the movable frame 2; the sleeve 422 is connected to the second fixing portion 421. The sleeve 422 is sleeved on the rotating shaft 5 and is distributed with the free end 4112 along the first axis X direction. The sleeve 422 has a third end wall 422a facing the first end wall 4112a along the first axis X direction. The third end wall 422a is recessed along the first axis X and towards the direction away from the first end wall 4112a to form an engaging portion 422b. It can be understood that the second fixing portion 421 is used to fix to the movable frame 2. In some embodiments, usually a screwing fixing method, a welding method, an adhesive method or other fixing methods are used to connect and fix it to the fixing frame 1 to ensure that the two can move simultaneously and will not loosen or displace during use. The above fixing methods are not limited in the present application as long as the fixing effect can be satisfied.

[0046] The sleeve 422 and the free end 4112 of the elastic portion 411 are distributed along the first axis X direction and correspond to the convex portion 4112c of the elastic portion 411. The sleeve 422 of the movable plate 42 has a third end wall 422a close to the first end wall 4112a. The third end wall 422a is recessed towards the direction away from the first end wall 4112a to form an engaging portion 422b, so as to form the cooperation between the convex portion 4112c and the engaging portion 422b, which is convenient for the automatic ejection of the bracket structure 1000.

[0047] Furthermore, the inner wall surface of the mating portion 422b is smoothly connected to the third end wall 422a, which can ensure that the convex portion 4112c can enter and leave the mating portion 422b without obstruction, ensuring that the convex portion 4112c can enter the mating portion 422b more smoothly, reducing resistance and jamming, and improving the reliability of the bracket structure 1000 when switching between the retracted position and the deployed position. When the inner wall surface of the mating portion 422b is smoothly connected to the third end wall 422a, it can also enhance the user experience, so that the user can feel a smoother operation experience and a smoother touch when using the bracket structure 1000, whether it is opening or closing.

[0048] Correspondingly, the fixing plate 41 further includes a limiting portion 413, which is connected to the first fixing portion 412 and extends toward the movable plate 42. The limiting portion 413 has a first limiting surface 4131, and the movable plate 42 has a second limiting surface 4221. The first limiting surface 4131 and the second limiting surface 4221 are arranged opposite to each other in the circumferential direction of the rotating shaft 5. It can be understood that when the bracket structure 1000 is in the deployed position, the first limiting surface 4131 of the fixing plate 41 and the second limiting surface 4221 of the movable plate 42 are in contact with each other to limit the rotation range of the movable plate 42 relative to the fixing plate 41. Moreover, by the contact between the first limiting surface 4131 and the second limiting surface 4221, it can be ensured that the movable plate 42 stops rotating after rotating a certain angle, thereby ensuring the stability of the bracket structure 1000 in the deployed position and reducing the occurrence of the situation that the movable plate 42 rotates excessively or loosens under external force.

[0049] To a certain extent, the limiting portion 413 can cooperate with the convex portion 4112c and the mating portion 422b to jointly limit the deployed position of the bracket structure 1000. The two act simultaneously, strengthening the positioning and limiting effect on the movable plate 42 and improving the angular accuracy of the bracket structure 1000 when it is deployed.

[0050] In some embodiments, the limiting portion 413 is sleeved on the rotating shaft 5. Since both the fixing plate 41 and the movable plate 42 are sleeved on the rotating shaft 5, the limiting portion 413 being sleeved on the rotating shaft 5 can facilitate the cooperation between the first limiting surface 4131 and the second limiting surface 4221 on the fixing plate 41 and the movable plate 42.

[0051] The limiting portion 413 and the elastic portion 411 are distributed at intervals along the first axis X direction. Both the limiting portion 413 and the elastic portion 411 are part of the fixing plate 41, but there is no mutual interference between the limiting portion 413 and the elastic portion 411. The limiting portion 413 does not affect the movement of the free end 4112 of the elastic portion 411 in the first axis X direction. When the movable plate 42 rotates, the limiting portion 413 and the elastic portion 411 can each play their functions and ensure that the cooperation between the convex portion 4112c and the mating portion 422b is not affected.

[0052] In some other embodiments, the limiting portion 413 is fixed relative to the fixed frame 1. It can be understood that when the movable plate 42 rotates, the limiting plate rotates relative to the fixed frame 1, which can provide a more stable limiting effect, ensuring that the movable plate 42 can contact the limiting portion 413 when it rotates to a certain angle, thereby reducing excessive rotation.

[0053] It can be understood that a second limiting surface 4221 is provided along one end of the sleeve 422 close to the limiting portion 413, and the sleeve 422 also has a matching portion 422b, thereby forming a linkage between the limiting effect and the matching effect of the matching portion 422b and the convex portion 4112c. When the matching portion 422b and the convex portion 4112c are matched, the sleeve 422 and the limiting portion 413 abut against each other to limit, thereby ensuring the stability of the bracket structure 1000 in the expanded position and reducing the occurrence of excessive rotation or loosening of the movable plate 42 due to external force.

[0054] Please refer to Figure 5 In some embodiments of the present application, the support structure 1000 further includes a second push member 6. In the folded position, the locking member 3 and the first push member 4 are respectively located at the two ends of the movable frame 2 along the first direction Y, and the second push member 6 is located between the locking member 3 and the first push member 4 along the first direction Y. The second push member 6 connects the movable frame 2 and the fixed frame 1, and is used to make the movable frame 2 rotate relative to the fixed frame 1 around the first axis X when the locking member 3 is in the unlocking position, so as to realize that the support structure 1000 is out of the folded position; wherein the first direction Y is perpendicular to the first axis X. It can be understood that the second push member 6 is used to provide additional thrust to the movable frame 2 when the locking member 3 releases the connection between the movable frame 2 and the fixed frame 1, so as to push the movable frame 2 to move around the first axis X, thereby realizing the unfolding of the support structure 1000, and the second push member 6 can work in conjunction with the first push member 4 to ensure that the support structure 1000 smoothly transitions from the folded position to the unfolded position.

[0055] In addition, the design of the second push member 6 improves the reliability of the switching of the support structure 1000 between the folded position and the unfolded position, reduces the possibility of the movable frame 2 being stuck or unable to unfold smoothly during the rotation process, and makes the movable frame 2 more stable during the unfolding process.

[0056] Specifically, the second pushing member 6 includes a first magnet 61 and a second magnet 62. The first magnet 61 and the second magnet 62 are respectively connected to the fixed frame 1 and the movable frame 2. In the retracted position, the polarities of the sides of the first magnet 61 and the second magnet 62 that are close to each other are the same. It can be understood that since the polarities of the sides of the first magnet and the second magnet that are close to each other are the same, a repulsive force can be provided. After the locking member 3 is unlocked, the fixed frame 1 and the movable frame 2 respectively connected to the first magnet 61 and the second magnet 62 are affected by the repulsive force, so that the movable frame 2 rotates around the first axis X in a direction away from the fixed frame 1 to realize the deployment of the bracket structure 1000, which can assist and link with the first pushing member 4, improve the reliability of the deployment of the bracket structure 1000, and is easy to operate.

[0057] In the embodiment of the present application, the fixed frame 1 and the movable frame 2 are provided with mounting grooves corresponding to the first magnet 61 and the second magnet 62 for mounting the first magnet 61 and the second magnet. Moreover, the first magnet 61 and the second magnet 62 can be better fixed by means of the mounting grooves. At the same time, the way of fitting and mounting will not additionally increase the thickness of the bracket structure 1000. Therefore, the thin and light state of the bracket structure 1000 can be ensured, which is convenient for users to carry.

[0058] The second pushing member 6 is arranged close to the locking member 3 along the first direction Y. Since one end of the movable frame 2 close to the locking member 3 is the free end 4112 during the rotation process, and the second pushing member 6 is arranged close to the free end 4112 of the movable frame 2. According to the lever principle of Li Yongle, during the rotation process of the movable frame 2, the second pushing member 6 can provide a longer force arm, so that the second pushing member 6 can generate a larger torque with a smaller force, and thus it is easier to drive the movable frame 2 to rotate.

[0059] Please refer to Figure 6 and Figure 7 As shown in, the locking member 3 is arranged on the fixed frame 1, and the movable frame 2 is provided with a locking groove 21. In the locked position, a part of the locking member 3 is located in the locking groove 21, and in the unlocked position, the locking member 3 moves out of the locking groove 21. It can be understood that by controlling the position change of a part of the locking member 3 in the locking groove 21, the locking member 3 can effectively lock or unlock the movable frame 2, with a simple structure, convenient operation, and reliable locking of the movable frame 2.

[0060] Please refer to Figure 8 and Figure 9, the locking member 3 includes a positioning shaft 31 and a rotating rod 32. The rotating rod 32 includes a pushing end 321, an operating end 322, and a middle portion 323 connected between the pushing end 321 and the operating end 322. The middle portion 323 is sleeved on the positioning shaft 31 and can rotate around the positioning shaft 31 to switch between a locking position and an unlocking position. The pushing end 321 is provided with a protrusion 3211. In the locking position, the protrusion 3211 is located in the locking groove 21, and in the unlocking position, the protrusion 3211 moves out of the locking groove 21. The positioning shaft 31 functions to limit the rotation of the rotating rod 32, so that the rotating rod 32 can only rotate in the axial direction of the positioning shaft 31. The pushing end 321 of the rotating rod 32 is provided with a protrusion 3211, and the protrusion 3211 can cooperate with the locking groove 21 on the movable frame 2 to achieve the locking function. The operating end 322 can control the rotation of the rotating rod 32. The user manually operates the operating end 322 of the rotating rod 32 to make it rotate around the positioning shaft 31. As the rotating rod 32 rotates, the protrusion 3211 moves out of the locking groove 21. When the protrusion 3211 completely moves out of the locking groove 21, the rotating rod 32 reaches the unlocking position, and the movable frame 2 can rotate freely. It can be understood that the locking member 3 not only realizes the locking and unlocking functions of the bracket structure 1000, but also ensures the simplicity of operation and the compactness of the structure, improving the user experience.

[0061] In addition, the locking member 3 further includes a reset member 33. The fixing frame 1 has a pushing surface, and the reset member 33 is arranged between the pushing surface and the pushing end 321. The reset member 33 is used to provide a restoring force when the locking switches from the unlocking position to the locking position, so that the locking member 3 automatically resets. It can be understood that the reset member 33 includes a spring, and the spring releases elastic force to push the pushing end 321 to rotate, so that the protrusion 3211 maintains the state when the locking member 3 is in the locking position, which is convenient for cooperating with the locking groove 21 when the movable frame 2 is retracted.

[0062] Please refer to Figures 7 to 8 , the locking member 3 further includes a trigger member 34. The fixing frame 1 forms a receiving groove 11, the operating end 322 is located in the receiving groove 11, one end of the trigger member 34 is located in the receiving groove 11 and is connected to the operating end 322, and the other end passes through the fixing frame 1 and protrudes from the outer wall of the fixing frame 1. For the convenience of user operation, the locking member 3 further includes a trigger member 34, and the trigger member 34 protrudes from the outer wall of the fixing frame 1. The user can control the position switching of the locking member 3 through the trigger member 34, and the operation is simple and convenient.

[0063] Please refer to Figure 5, in order to further reduce the thickness of the bracket structure 1000, the surface of the fixed bracket 1 has a receiving groove 12. When the bracket structure 1000 is in the retracted position, the movable bracket 2 is received in the receiving groove 12. It can be understood that the size and shape of the receiving groove 12 match the movable bracket 2. When the movable bracket 2 is completely received in the receiving groove 12, the surface of the movable bracket 2 is flush with the surface of the fixed bracket 1, which can ensure the consistency and aesthetics in appearance while reducing the overall thickness.

[0064] In some embodiments of the present application, the fixed bracket 1 includes a protective shell 13. The movable bracket 2 is rotatably connected to the protective shell 13, and the locking member 3 and the first pushing member 4 are both connected to the protective shell 13. An electronic device receiving cavity is formed on the side of the protective shell 13 facing away from the movable bracket 2. The protective shell 13 can be applied to an electronic device, so as to support the electronic device.

[0065] In addition, the bracket structure 1000 further includes a charging device, and the charging device is connected to the protective shell 13. In some embodiments, the bracket structure 1000 is also integrated with a charging device, which is convenient for charging while providing a supporting effect. The charging device can be a wireless charging component, a wired charging component, etc., and the present application does not limit this here.
