Description

An accessory for an electronic device Technical Field

[0001] This invention relates to the field of electronic device accessories technology, and in particular to an accessory for an electronic device. Background Technology

[0002] With the continuous development and advancement 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 stand component of an electronic device accessory includes a stand that can rotate relative to the accessory's main body, allowing the accessory to be in a supported or stowed state. However, regardless of whether the stand component is in a supported or stowed state, the rotating structure of existing electronic device accessories is exposed on the exterior of the product. This not only affects the overall aesthetics of the accessory but also makes the exposed rotating structure susceptible to damage, thus affecting the lifespan of the electronic device accessory.

[0003] Utility Model Content

[0004] This application provides an accessory for an electronic device that, in its stowed state, conceals the rotation center of a support member below the support member, thereby improving the performance of the accessory for the electronic device.

[0005] This application provides an accessory for an electronic device, the accessory comprising:

[0006] The main body is provided with a receiving groove, the receiving groove having a bottom wall and a first side wall;

[0007] A support assembly includes a support member and a connecting member. The connecting member is connected between the bottom wall and the support member. The support member is rotatably connected to the main body through the connecting member, so that the support member can rotate relative to the main body about a rotation center, and the rotation center can move relative to the main body.

[0008] The support member has a supported state and a retracted state. In the retracted state, at least a portion of the support member is housed in the receiving groove, and the rotation center is located within the projection range of the support member toward the bottom wall.

One end of the linkage is rotatably connected to the support member via the first rotating shaft, and the other end of the linkage is rotatably connected to the main body via the second rotating shaft. The axis of the first rotating shaft is the rotation center.

[0016] In the stored state, the first pivot, the linkage, and the second pivot are located within the projection range of the support member toward the bottom wall.

[0017] In one specific embodiment, in the stored state, the linkage and the bottom wall have a first included angle α1, and in the supported state, the linkage and the bottom wall have a second included angle α2. The first included angle α1 satisfies: 0≤α1≤8°, and / or the second included angle α2 satisfies: 10°≤α2<90°.

[0018] In one specific embodiment, the connecting member further includes a first connecting member and a second connecting member. The first connecting member is fixedly connected to the support member, and the second connecting member is fixedly connected to the main body. The linkage member is rotatably connected to the first connecting member through the first rotating shaft, and the linkage member is rotatably connected to the second connecting member through the second rotating shaft.

[0019] In one specific embodiment, the first connecting member includes a first bushing portion, the second connecting member includes a second bushing portion, and the linkage member includes a first body portion and a first sleeve portion and a second sleeve portion located at both ends of the first body portion. The first bushing portion and the first sleeve portion are sleeved on the first rotating shaft, and the second bushing portion and the second sleeve portion are sleeved on the second rotating shaft.

[0020] The first socket portion is provided with a first stop opening, the second socket portion is provided with a second stop opening, the first connector has a first stop block, and the second connector has a second stop block;

[0021] When the support member is in the supported state, the first stop block abuts against the first stop surface of the first stop opening, and the second stop block abuts against the second stop surface of the second stop opening.

[0022] In one specific embodiment, the support assembly further includes a base, which is rotatably mounted in the receiving groove, and the second connector is fixedly connected to the main body via the base;

[0023] In the stored state, the support member covers the base, and the linkage member, the first rotating shaft, and the second rotating shaft are housed between the support member and the base.

[0024] In one specific embodiment, the base and the support member have a first receiving cavity and a second receiving cavity. When the bracket assembly is in the storage state, the first receiving cavity is used to receive the first rotating shaft and the first sleeve portion and the first shaft sleeve portion sleeved on the first rotating shaft, and the second receiving cavity is used to receive the second rotating shaft and the second sleeve portion and the second shaft sleeve portion sleeved on the second rotating shaft.

[0025] In one embodiment, the base has a first receiving portion, a second receiving portion and a third receiving portion, the third receiving portion being located between and communicating with the first receiving portion and the second receiving portion, and the support member having a fourth receiving portion and a fifth receiving portion;

[0026] When the bracket assembly is in the stored state, the first accommodating part and the fourth accommodating part form the first accommodating cavity, and the second accommodating part and the fifth accommodating part form the second accommodating cavity;

[0027] When the support assembly is in the stored state, the third receiving portion is used to accommodate a part of the linkage.

[0028] In one specific embodiment, the base is further provided with a first mounting groove, a portion of the second connector is embedded in the first mounting groove and fixedly connected to the base, and the support is further provided with a second mounting groove, a portion of the first connector is embedded in the second mounting groove and fixedly connected to the support.

[0029] In one specific embodiment, the linkage includes a plurality of connecting pieces stacked along their own thickness direction, with the first socket portions of adjacent connecting pieces welded to each other, the second socket portions of adjacent connecting pieces welded to each other, and / or each connecting piece having the same thickness.

[0030] In one embodiment, the support member has a first end facing the first sidewall, and during the process of rotating the support member from the stored state to the supported state, the first end abuts against the first sidewall.

[0031] In one specific embodiment, when the included angle between the support member and the bottom wall is a third included angle θ1, the first end abuts against the first side wall, and the third included angle θ1 satisfies: 25°≤θ1≤45°.

[0032] In one specific embodiment, the first sidewall is provided with a buffer layer.

[0033] In one specific embodiment, the thickness D of the main body satisfies: 1.5mm≤D≤2.5mm.

[0034] In this application, when the bracket is in the retracted state, the support member is housed within the receiving groove, and the rotation center of the support member is hidden beneath it, improving the aesthetics of the accessory. When the support member is rotated to switch from the retracted state to the supported state, it rotates around its rotation center, causing it to stand upright and support the electronic device accessory. Compared to the retracted state, in the supported state, the rotation center is farther from the bottom wall and the first side wall of the receiving groove. That is, during the rotation from the retracted state to the supported state, the rotation center moves away from both the bottom wall and the first side wall, causing the first end of the support member to move away from the first side wall. This reduces the risk of interference between the first end and the first side wall, which could hinder further rotation, allowing the support member to open to the user's desired angle and meet their usage needs.

[0035] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0065] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] Please refer to Figures 1 and 2. Figure 1 is a partial structural diagram of an accessory for an electronic device in a specific embodiment of the related art, and Figure 2 is a structural diagram of the accessory in Figure 1 in a supported state. As shown in Figure 1, the accessory for the electronic device includes an accessory body 10 and a bracket 20. A groove 101 is provided on the back of the accessory body 10. The groove 101 has a bottom wall 102 and a side wall 103. The bracket 20 is rotatably connected to the bottom wall 102 via a pivot 202, thereby allowing the bracket 20 to switch between a supported state and a retracted state. As shown in Figure 1, the bracket 20 is in the retracted state. At this time, both the bracket 20 and the pivot 202 are housed within the groove 101. To make the retracted state more aesthetically pleasing, the pivot 202 needs to be hidden. Typically, the pivot 202 is hidden inside the bracket 20, that is, the bracket 20 covers the pivot 202. In order to hide the pivot 202, the end 201 of the bracket 20 usually needs to be closer to the side wall 103 of the groove 201, so as to ensure that the pivot 202 can be hidden between the bracket 20 and the bottom wall 102 of the groove 101 when stored.

[0072] However, when the bracket 20 switches from the storage state shown in Figure 1 to the support state shown in Figure 2, during the rotation of the bracket 20 around the pivot 202, there is a risk that the end 201 of the bracket 20 may interfere with the side wall 201 of the groove 101, causing the side wall 103 to block the bracket 20 from opening further. This may prevent the bracket 20 from opening to the angle required by the user, affecting the normal use of the bracket 20 and the accessories of the electronic device.

[0073] This application prevents the bracket from interfering with the sidewall of the groove during the opening process, thus avoiding the problem of the bracket being unable to open, by changing the position of the rotation center of the bracket.

[0074] Please refer to Figures 3-6. Figure 3 is a structural schematic diagram of the electronic device accessory provided in this application in a specific embodiment. Figure 4 is an exploded view of Figure 3. Figure 5 is a cross-sectional view along line AA of Figure 3. Figure 6 is a partial enlarged view of part I in Figure 5. In this embodiment of the application, as shown in Figures 3 and 4, the electronic device accessory includes a main body 1 and a support assembly 2. The main body 1 can specifically be a protective shell for the electronic device. The support assembly 2 includes a support member 21 rotatably connected to the main body 1. When the support member 21 rotates, it can open relative to the main body 1, thereby supporting the main body 1. The support member 21 and the main body 1 can be rotatably connected via a pivot shaft or other means, as long as the support member 21 can rotate freely relative to the main body 1.

[0075] As shown in Figures 3-5, a receiving groove 11 is provided on the back of the main body 1. The receiving groove 11 is used to accommodate at least a portion of the structure of the support member 21 in the stored state. In some embodiments, the support member 21 of the bracket assembly 2 can be an annular structure, and the receiving groove 11 can also be an annular structure. The annular receiving groove 11 has a boss 113 inside. When the bracket assembly 2 is in the stored state, the support member 21 is sleeved on the outside of the boss 113.

[0076] The structure of the main body 1 receiving groove 11 and the bracket assembly 2 in Figure 6 can be simplified to the structure shown in Figure 7. In Figure 7, the upper part shows the bracket assembly 2 in the supported state, and the lower part shows the bracket assembly 2 in the retracted state. When the bracket assembly 2 is in the retracted state, at least a portion of the support member 21 is housed within the receiving groove 11, and the rotation center A1 of the support member 21 is hidden below it, improving the aesthetics of the accessory. When the support member 21 is rotated to switch from the retracted state to the supported state, the support member 21 rotates around the rotation center A1, causing the support member 21 to stand upright for supporting the electronic device accessory. The rotation center A1 is movable relative to the main body 1.

[0077] Comparing the stowed and supported states shown in Figure 7, it can be seen that, compared to the stowed state, the position of the rotation center A1 relative to the bottom wall 111 and the first side wall 112 of the receiving groove 11 changes in the supported state. In Figure 7, the thick dashed line represents the position of the rotation center A1 in the stowed state, and the thick dotted line represents the position of the rotation center A1 in the supported state. As can be seen from the comparison, when in the supported state, compared to the stored state, the rotation center A1 is away from the bottom wall 111 of the receiving groove 11 and away from the first side wall 112 of the receiving groove 11. That is, during the process of the support member 21 rotating from the stored state to the supported state, the rotation center A1 is away from the bottom wall 111 and the first side wall 112 of the receiving groove 11, so that the first end 211 of the support member 21 moves away from the first side wall 112 and the bottom wall 111. Thus, during the process of the support member 21 rotating from the stored state to the supported state, the risk of interference between the first end 211 and the first side wall 112 and the bottom wall 111, which would prevent the first side wall 112 and the bottom wall 111 from continuing to rotate, can be reduced, so that the support member 21 can open to the angle required by the user and meet the user's usage needs.

[0078] The first sidewall 112 of the receiving groove 11 refers to the sidewall of the receiving groove 11 on the side of the rotation center A1. When the receiving groove 11 is circular or annular, the first sidewall 112 can be a portion of the sidewall of the 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 A1. In addition, when the receiving groove 11 is circular or annular, the receiving groove 11 also includes a second sidewall 114 opposite to the first sidewall 112.

[0079] In another specific embodiment, the rotation center A1 in the supported state, relative to the stored state, can change only in position relative to the bottom wall 111 of the receiving groove 11. That is, compared to the stored state, in the supported state, the rotation center A1 is away from the bottom wall 111 of the receiving groove 11. During the rotation of the support member 21 from the stored state to the supported state, the rotation center A1 moves away from the bottom wall 111 of the receiving groove 11. This reduces the risk of the bottom wall 111 hindering the continued rotation of the support member 21 due to interference between the first end 211 and the bottom wall 111. Simultaneously, when the rotation center A1 moves away from the bottom wall 111 of the receiving groove 11 and the first end 211 of the support member 21 disengages from the receiving groove 11, the first end 211 will not interfere with the first side wall 112 of the receiving groove 11 during the rotation of the support member 21. This allows the support member 21 to open to the angle required by the user, meeting the user's usage needs.

[0080] In another specific embodiment, the rotation center A1 in the supported state, relative to the stored state, can change only in position relative to the first sidewall 112 of the receiving groove 11. That is, compared to the stored state, in the supported state, the rotation center A1 moves away from the first sidewall 112 of the receiving groove 11. In other words, during the process of the support member 21 rotating from the stored state to the supported state, the rotation center A1 moves away from the first sidewall 112 of the receiving groove 11, causing the first end 211 of the support member 21 to move away from the first sidewall 112. This reduces the risk of interference between the first end 211 and the first sidewall 112 during the rotation of the support member 21 from the stored state to the supported state, thus preventing the first sidewall 112 from hindering the continued rotation of the support member 21. This allows the support member 21 to open to the angle required by the user, meeting the user's usage needs.

[0081] The following description uses the example of the support member 21 rotating from a stored state to a supported state, with its rotation center A1 moving along the bottom wall 111 away from the receiving groove 11 and along the first side wall 112 away from the receiving groove 11. In the embodiment shown in FIG. 7, the support member 21 is directly rotatably connected to the main body 1. In other embodiments, as shown in FIG. 8, the bracket assembly 2 may also include a base 22, which is rotatably mounted in the receiving groove 11, i.e., the base 22 can be a turntable-like structure. The support member 21 is rotatably connected to the base 22, so that the support member 21 and the main body 1 are rotatably connected through the base 22.

[0082] Please refer to Figures 9 and 10. Figure 9 shows the cooperation between the support assembly and the main body when the support assembly is in the retracted state, and Figure 10 shows the cooperation between the support assembly and the main body when the support assembly is in the supported state. The purpose of this embodiment is to hide the rotation center A1 in the receiving groove 11 when the support assembly 2 is in the retracted state. When the depth H of the receiving groove 11 is large, hiding the rotation center A1 is relatively easy to achieve. When the depth H of the receiving groove 11 is small, the setting positions of each component of the support assembly 2 are small, and there is a risk that the components of the support assembly 2 will interfere with each other during the rotation of the support member 21. Taking a mobile phone case as an example of an electronic device accessory, in order to improve the user experience, the weight of the electronic device accessory cannot be too large, which requires that the thickness of the main body 1 of the accessory cannot be too large. Under normal circumstances, the thickness D of the main body 1 satisfies: 1.5mm≤D≤2.5mm. For example, the thickness D of the main body 1 can be 1.5mm, 1.7mm, 1.8mm, 1.9mm, 2mm, 2.1mm, 2.5mm, etc. The weight of the electronic device accessory within this thickness range will not be too large, ensuring the user experience. However, the thickness of the main body 1 within this thickness range is relatively small, resulting in a relatively small depth of the receiving groove 11. For example, the depth H of the receiving groove 11 satisfies: 1.2mm ≤ H ≤ 2mm. Therefore, the technical challenge that this application needs to overcome is how to achieve the concealment of the rotation center A1 when the depth of the receiving groove 11 is small.

[0083] As shown in Figure 9, when the support assembly 2 is in the retracted state, the distance between the rotation center A1 and the first sidewall 112 is L1. As shown in Figure 10, when the support assembly 2 is in the supported state, the distance between the rotation center A1 and the first sidewall 112 is L2. Comparing Figures 9 and 10, it can be seen that L2 is greater than L1.

[0084] In some embodiments, L1 satisfies: 0.6mm ≤ L1 ≤ 1.0mm. For example, L1 can be 0.6mm, 0.65mm, 0.7mm, 0.75mm, 0.85mm, 0.9mm, 0.95mm, 1mm, etc. When L1 is within this range, while hiding the rotation center A1 below the support member 21, the gap between the first end 121 of the support member 21 and the first sidewall 112 of the receiving groove 11 is small enough that the gap between the support member 21 and the first sidewall 112 is not easily visible when the support member 21 is in the retracted state, thus improving the aesthetics of the electronic device accessories when the support member 21 is in the retracted state. In addition, when the gap between the first end 121 of the support member 21 and the first sidewall 112 is small, dust is less likely to enter below the support member 21, thereby reducing the impact of dust and other impurities on the lifespan of the connecting member 23 and improving the cleanliness of the electronic device accessories.

[0085] In some embodiments, L2 satisfies: L2 ≥ 0.5 mm. For example, L2 can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.5 mm, 2 mm, etc. During the process of switching the support member 21 from the storage state to the support state, when L2 is within this range, it can ensure that the support member 21 can be opened normally without interfering with the first side wall 121 and thus preventing it from being unable to open. At the same time, it can minimize the movement distance of the rotation center A1, thereby ensuring that the support member 21 can be opened normally while making the width of the receiving groove 11 smaller, making the bracket assembly 2 more compact, and avoiding interference between the bracket assembly 2 and the electronic device or other accessories of the electronic device.

[0086] As shown in Figure 9, when the support assembly 2 is in the retracted state, the distance between the rotation center A1 and the bottom wall 111 is L3. As shown in Figure 10, when the support assembly 2 is in the supported state, the distance between the rotation center A1 and the bottom wall 111 is L4. Comparing Figures 9 and 10, it can be seen that L4 is greater than L3.

[0087] In some embodiments, L3 satisfies: 0.5mm ≤ L3 ≤ 1.0mm. L4 satisfies: L4 ≥ 1.0mm. For example, L3 can be 0.5mm, 0.6mm, 0.65mm, 0.7mm, 0.8mm, 0.9mm, 1mm, etc. L4 can be 1mm, 1.2mm, 1.5mm, 1.6mm, 1.8mm, 2mm, 2.2mm, 2.4mm, 2.5mm, 2.8mm, 3mm, 3.1mm, 3.3mm, 3.5mm, etc.

[0088] As shown in Figure 9, when L3 is too large, with a fixed depth H of the receiving groove 11, the distance between the rotation center A1 and the surface 12 of the main body 1 is too small. This causes the support member 21 to protrude from the surface 12 of the main body 1 when the bracket assembly 2 is in the retracted state, or causes the thickness of the support member 21 to be too small. When L3 is too small, with a fixed depth H of the receiving groove 11, the distance between the rotation center A1 and the surface 12 of the main body 1 is too large. This results in a higher risk of interference between the first end 211 of the support member 21 and the first sidewall 112 of the receiving groove 11 during the process of switching the bracket assembly 2 from the retracted state to the supported state. Therefore, when 0.5mm≤L3≤1.0mm, and the depth H of the receiving groove 11 is constant, the distance between the rotation center A1 of the support member 21 and the surface 12 of the main body 1 is moderate. This will not cause the support member 21 to protrude from the surface 12 of the main body 1 when it is in the storage state, nor will it cause the support member 21 to interfere with the first side wall 112 during rotation. This will improve the state of the electronic device accessories in the storage state so that they can meet the user's usage needs and ensure that the support member 21 can be opened to the angle required by the user.

[0089] As shown in Figures 9 and 10, the surface 12 of the main body 1 is the end face opposite to the bottom wall 111 of the receiving groove 11 along the thickness direction of the main body 1, and the receiving groove 11 is formed by recessing inward from the surface 12 of the main body 1.

[0090] As shown in Figure 10, when L4 is too small, the distance between the support member 21 and the bottom wall 111 of the receiving groove 11 is too small when the support assembly 2 is in the supported state. This results in the rotation center A1 moving too far away from the bottom wall 111 during the process of switching the support assembly 2 from the stored state to the supported state, posing a risk of interference between the first end 211 and the first side wall 112 during the rotation of the support member 21. In this embodiment, when L4 ≥ 1.0 mm, the risk of damage to the support assembly 2 due to impact in the supported state is low, and the risk of interference between the first end 211 and the first side wall 112 of the receiving groove 11 during the rotation of the support member 21 is effectively reduced, allowing the support member 21 to open to the preset angle required by the user.

[0091] As shown in Figure 9, when the bracket assembly 2 is in the storage state, the rotation center A1 is located on the side of the surface 12 of the main body 1 facing the bottom wall 111, that is, the rotation center A1 is lower than the surface 12 of the main body 2, and the distance between the rotation center A1 and the surface 12 of the main body 1 is L5.

[0092] As shown in Figure 10, when the support assembly 2 is in the supported state, the distance between the rotation center A1 and the surface 12 of the main body 1 is L6. At this time, the rotation center A1 can be located on the side of the surface 12 of the main body 1 facing away from the bottom wall 111, that is, the rotation center A1 is located outside the receiving groove 11 (as shown in the embodiment of Figure 10), and the plane containing the rotation center A1 is higher than the surface 12 of the main body 1 (i.e., L6 > 0). In other embodiments, when the support assembly 2 is in the supported state, the rotation center A1 can be flush with the surface 12 of the main body 1 (i.e., L6 = 0).

[0093] In some embodiments, L5 satisfies: 0.5mm ≤ L5 ≤ 2.5mm. For example, L5 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.3mm, 1.5mm, 2mm, 2.5mm, etc.

[0094] As shown in Figure 9, when L5 is too large, there is a high risk of interference between the first end 211 of the support member 21 and the first sidewall 112 of the receiving groove 11 during the transition of the bracket assembly 2 from the retracted state to the supported state. When L5 is too small, the distance between the rotation center A1 and the surface 12 of the main body 1 is too small, causing the support member 21 to protrude from the surface 12 of the main body 1 when the bracket assembly 2 is in the retracted state, or causing the thickness of the support member 21 to be too small. Therefore, when 0.5mm≤L5≤2.5mm, the distance between the rotation center A1 of the support member 21 and the surface 12 of the main body 1 is moderate, preventing the support member 21 from protruding from the surface 12 of the main body 1 or the thickness of the support member 21 from being too small when in the retracted state, and also preventing interference between the support member 21 and the first sidewall 112 during rotation. This improves the functionality of the electronic device's accessories in the retracted state, ensuring that they meet the user's needs and that the support member 21 can be opened to the user's desired angle.

[0095] In one specific embodiment, please refer to Figure 11, which is a schematic diagram of the bracket assembly and the main body in a stowed state and a supported state. When the bracket assembly 2 is in the stowed state, the rotation center A1 (shown by the solid line in Figure 11) is located in the first position. During the process of the support member 21 switching from the stowed state to the supported state, the rotation center A1 gradually deviates from the first position. The dashed line in Figure 11 shows the situation where the rotation center A1 deviates from the first position. During the process of the support member 21 rotating from the stowed state to the supported state, the rotation center A1 moves away from the first position along the first direction X, and the rotation center A1 moves away from the first position along the second direction Y. Here, the first direction X refers to the thickness direction of the main body 1, and the second direction Y refers to the direction perpendicular to the first direction X. For example, the second direction Y can be the length direction of the electronic device's accessory. In other embodiments, the second direction Y can also be the width direction of the electronic device's accessory, or it can be any direction in the plane perpendicular to the thickness direction of the accessory. In the embodiment shown in Figure 11, the second direction Y is the length direction of the electronic device.

[0096] The following describes in detail how the rotation center A1 moves away from the bottom wall 111 and the first side wall 112 during the process of rotating the support member 21 from the storage state to the support state.

[0097] Please continue to refer to Figures 12 and 13. Figure 12 is a cross-sectional view of the electronic device's components in the supported state, and Figure 13 is a partial enlarged view of part II in Figure 12. As shown in Figure 12, when the electronic device's components are in the supported state, the support member 21 stands upright relative to the surface of the main body 1, thereby enabling it to support the electronic device.

[0098] In one specific embodiment, as shown in Figures 14 and 15, Figure 14 is an exploded view of the bracket assembly in one specific embodiment, and Figure 15 is a structural schematic diagram of the bracket assembly in Figure 14 in a supported state. The bracket assembly 2 also includes a connecting member 23, through which the support member 21 and the base 22 are rotatably connected. The base 22 provides space for the connecting member 23, eliminating the need for the connecting member 23 to occupy additional space between the support member 21 and the base 22 for storage, thus saving internal space in the bracket assembly 2 and reducing the overall thickness of the bracket assembly 2, thereby reducing the overall thickness of the electronic device accessories.

[0099] In other embodiments, the bracket assembly 2 may also include only the support member 21, with one end of the connecting mechanism 23 connected to the support member 21 and the other end connected to the main body 1. The following description uses an embodiment where the bracket assembly 2 includes the support member 21, the base 22, and the connecting member 23 as an example.

[0100] As shown in Figure 14, when the bracket assembly 2 is in the retracted state, the support member 21 overlaps the base 22 and covers the connecting mechanism 23. That is, along the thickness direction of the bracket assembly 2, the projection of the connecting mechanism 23 lies within the projection of the support member 21 towards the bottom wall 111, thus concealing the connecting mechanism 23 inside the bracket assembly 2. This prevents the connecting mechanism 23 from being exposed on the outside of the bracket assembly 2, thus avoiding wear or dust accumulation and extending its service life. Simultaneously, when the material and color of the connecting mechanism 23 differ significantly from that of the support member 21, this design improves the consistency of the bracket assembly 2's appearance in the retracted state, thereby enhancing the aesthetics of the entire electronic device's components and ultimately improving the user experience.

[0101] As shown in Figure 15, when the support assembly 2 is in the supported state, the support member 21 rotates relative to the base 22 away from the base 22 through the connecting member 23, so that the support member 21 and the main body 1 (shown in Figure 12) form a certain angle, so that the support member 21 supports the main body 1 and keeps the support member 21 in an upright state.

[0102] The specific structure of the connecting member 23 is described in detail below.

[0103] Please refer to Figures 16-18. Figure 16 is an exploded view of the connecting member in Figures 14 and 15 in a specific embodiment. Figure 17 is a structural schematic diagram of the connecting member in Figure 16 in the stowed state. Figure 18 is a structural schematic diagram of the connecting member in Figure 16 in the supported state. As shown in Figure 16, the connecting member 23 includes a linkage 231, a first rotating shaft 232, and a second rotating shaft 233. One end of the linkage 231 is rotatably connected to the support member 21 via the first rotating shaft 232, and the other end of the linkage 231 is rotatably connected to the base 22 via the second rotating shaft 233. Please also refer to Figure 6. When the support member 21 is in the stowed state, it overlaps the base 22. When the support member 21 switches from the stowed state to the supported state, the center of the first rotating shaft 232 at the connection between the support member 21 and the linkage 231 is the aforementioned rotation center A1. The support member 21 can rotate around the first rotating shaft 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 231 and the base 22 is another rotation center of the linkage 231. As the support 21 rotates, the linkage 231 can rotate around the second pivot 233 in a direction away from the bottom wall 111 and the first side wall 112 of the receiving groove 11. That is, the angle between the linkage 231 and the base 22 gradually increases, thereby driving the support 21 to move away from the bottom wall 111 and the first side wall 112.

[0104] As can be seen from the above, and in conjunction with Figures 6 and 13, when the support member 21 rotates 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 A1 of the linkage member 231 to move upward and to the right (views shown in Figures 3 and 6). This reduces the risk that the first end 211 of the support member 21 will interfere with the first sidewall 112 of the receiving groove 11 during the transition of the bracket assembly 2 from the storage state to the support state, preventing the support member 21 from continuing to rotate. This makes the rotation of the support member 21 no longer restricted, increases the rotation angle of the support member 21, and enables the bracket assembly 2 to meet the user's needs, thus improving the user experience.

[0105] In the embodiment shown in Figure 6, when the bracket assembly 2 is in the storage state, the linkage 23 and the bottom wall 111 (or base 22) of the receiving groove 11 have a first included angle α1, which satisfies: 0≤α1≤8°. For example, α1 can be 0°, 0.1°, 1°, 3°, 5°, 6°, 7°, 8°, etc.

[0106] In this embodiment, a first included angle exists between the linkage 23 and the bottom wall 111 to facilitate the switch of the bracket assembly 2 from the storage state to the support state. When the first included angle α1 is too large, in the storage state, the space occupied by the linkage 23 along the thickness direction of the electronic device's accessories is too large, which is not conducive to the arrangement of the bracket assembly 2 in the shallow receiving groove 11.

[0107] In the embodiment shown in Figure 13, when the support assembly 2 is in the supported state, the linkage 23 and the bottom wall 111 (or base 22) of the receiving groove 11 have a second included angle α2, which satisfies: 10° ≤ α2 < 90°. Here, the second included angle α2 represents the angle between the linkage 23 and the bottom wall 111 of the receiving groove 11 when the support 21 is opened to its maximum angle. For example, the second included angle α2 can be: 10°, 15°, 20°, 30°, 40°, 45°, 50°, 60°, 70°, 80°, 85°, etc.

[0108] When the second included angle α2 is too small, there is a risk that the rotation center A1 cannot be raised to a suitable height, which may cause the first end 121 of the support member 12 to interfere with the first sidewall 112 of the receiving groove 11, thus preventing the support member 12 from continuing to rotate. When the support member 12 is in the support state shown in Figure 10, it mainly supports the main body 1 and the electronic device. When the second included angle α2 is greater than 90°, in addition to the support by the support member 12, the connecting member 23 will also participate in the support. That is, the connecting member 23 will bear the external force of the main body 1 and the electronic device. After the connecting member 23 is deformed by the force, there is a risk that it will affect its normal rotation, causing the support member 12 to be unable to rotate normally.

[0109] Therefore, when α2 ≥ 10°, it can be ensured that during the process of rotating the support member 12 from the stored state to the supported state, the rotation center A1 can be moved away from the bottom wall 111 and the first side wall 112, thereby preventing the rotation center A1 from interfering with the first side wall 112 and causing the support member 12 to be unable to continue rotating, so that the support member 12 can rotate to the angle required by the user. Moreover, when α2 < 90°, it can make the rotation of the support member 12 less strenuous and prevent the rotation center A1 from deviating too much from the initial position, making the support of the support member 12 more stable and avoiding stress on the connecting member 23.

[0110] In some embodiments, as shown in Figures 16-18, the connecting member 23 may further include a first connecting member 234 and a second connecting member 235. The first connecting member 234 is fixed to the support member 21, and the second connecting member 235 is fixed to the base 22. The first connecting member 234 and the second connecting member 235 are rotatably connected so that the support member 21 can rotate relative to the base 22. The length of the first connecting member 234 is greater than the length of the second connecting member 235. Since the support member 21 will rotate multiple times during use, it is necessary to ensure sufficient connection strength between the first connecting member 234 and the support member 21 to prevent loosening or even detachment between them. This embodiment of the application increases the size of the first connector 234, thereby increasing the connection area between the first connector 234 and the support 21. This improves the connection strength between the first connector 234 and the support 21, thus enhancing the stability and reliability of their connection. It also reduces the possibility of the first connector 234 and the support 21 becoming loose or detached during use, thereby improving the overall stability and reliability of the bracket assembly 10. Simultaneously, increasing the size of the first connector 234 improves the structural stability of the first connector 234 itself, reducing the possibility of bending, deformation, or even breakage, and thus extending the service life of the bracket assembly 10. On the other hand, the relatively small size of the second connector 235 connected to the base 22 reduces the space occupied by the second connector 235 on the base 22, saving installation space and allowing for the placement of magnets and other components on the base 22, further improving the overall reliability of the bracket assembly 10.

[0111] One end of the linkage 231 is rotatably connected to the first connecting member 234 via the first rotating shaft 232, thereby indirectly connecting the linkage 231 and the support member 21 via the first connecting member 234. The other end of the linkage 231 is rotatably connected to the second connecting member 235 via the second rotating shaft 233, thereby indirectly connecting the linkage 231 and the base 22 via the second connecting member 235. When the support member 21 switches from the storage state to the support 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, thereby driving the support member 21 to move away from the bottom wall 111 and the first side wall 112 of the receiving groove 11.

[0112] In one specific embodiment, as shown in FIG16, the first connector 234 includes a second body portion 2342 and a first bushing portion 2341 connected to one end of the second body portion 2342. A first rotating shaft 232 passes through the first bushing portion 2341 and is rotatable relative to the first bushing portion 2341. The first bushing portion 2341 has a first notch to avoid the first socket portion 2312 of the linkage 231, reducing the possibility of interference between the linkage 231 and the first connector 234. Similarly, the second connector 235 includes a third body portion 2352 and a second bushing portion 2351 connected to one end of the third body portion 2352. A second rotating shaft 233 passes through the second bushing portion 2351 and is rotatable relative to the second bushing portion 2351. The second bushing portion 2351 has a second notch, which is used to avoid the first sleeve portion 2312 of the linkage 231, thereby reducing the possibility of interference between the linkage 231 and the second connecting member 235.

[0113] Please refer to Figure 19, which is a structural schematic diagram of the linkage in Figure 16 in a specific embodiment. As shown in Figure 19, and continuing to refer to Figure 16, the first socket 2312 is provided with a first stop opening 2312a, and the second socket 2313 is provided with a second stop opening 2313a. As shown in Figure 18, the first connector 2312 has a first stop block 2343, and the second connector 2313 has a second stop block 2353. During the rotation of the first connector 2312, the first stop block 2343 can move within the first stop opening 2312a, and during the rotation of the second connector 2313, the second stop block 2353 can move within the second stop opening 2313a. When the bracket assembly 2 is in the supported state, the connecting member is in the unfolded state as shown in Figure 18. At this time, the first stop block 2343 abuts against the first stop surface of the first stop opening 2312a, thereby limiting the rotation angle of the first connecting member 2312. The second stop block 2353 abuts against the second stop surface of the second stop opening 2313a, thereby limiting the rotation angle of the second connecting member 2313. This restricts the first connecting member 2312 and the second connecting member 2313 to the unfolded state as shown in Figure 18, thereby limiting the angle through which the support member 21 rotates relative to the bottom wall 111 of the receiving groove 11. This allows the support member 21 to maintain its current angle, improving the support stability of the bracket assembly 2 in the supported state and enhancing the user experience.

[0114] Referring to Figure 19, in one specific embodiment, the linkage 231 includes multiple connecting pieces stacked along its own thickness direction, and each connecting piece has the same thickness. This makes the force on each connecting piece more uniform during the rotation of the linkage 231, thereby improving the force that the linkage 231 can withstand. Moreover, when each connecting piece has the same thickness, multiple connecting pieces can be processed using standardized processes. After the connecting pieces are formed, corresponding operations can be performed on the connecting pieces as needed (e.g., setting openings), which can improve the processing efficiency of the connecting pieces, thereby improving the production efficiency of the linkage 231.

[0115] Please refer to Figures 20 and 21. Figure 20 is a schematic diagram of the structure of the first connecting piece in Figure 19 in one specific embodiment, and Figure 21 is a schematic diagram of the structure of the second connecting piece in Figure 19 in one specific embodiment. The linkage 231 may include a plurality of first connecting pieces 2314 as shown in Figure 20 and a plurality of second connecting pieces 2315 as shown in Figure 21. The first connecting pieces 2314 and the second connecting pieces 2315 each include a first body portion 2311, a first socket portion 2312 and a second socket portion 2313, and the first body portion 2311 of the first connecting pieces 2314 and the second connecting pieces 2315 has the same structure. The first socket portion 2312 and the second socket portion 2313 of the first connecting piece 2314 are both closed structures. The first socket portion 2312 of the second connecting piece 2315 is provided with a first notch 2314a, and the second socket portion 2313 of the second connecting piece 2315 is provided with a second notch 2314b. After multiple second connecting pieces 2315 are stacked along their own thickness direction, each first notch 2314a forms the first stop opening 2312a of the linkage member 231, and each second notch 2314b forms the second stop opening 2313a of the linkage member 231.

[0116] As shown in Figure 21, the central angle of the first notch 2314a is smaller than the central angle of the second notch 2314b, which makes the central angle of the first stop opening 2312a smaller than the central angle of the second stop opening 2313a. This makes the rotatable angle of the second stop block 2353 greater than the rotatable angle of the first stop block 2343. In other words, the rotatable angle of the second connector 235 connected to the support member 21 is greater than the rotatable angle of the first connector 234 connected to the base 22. This allows the support member 21 to open at a wider range of angles to meet different user needs.

[0117] As shown in Figure 19, the first socket portion 2312 of multiple connecting pieces is welded to form at least one weld 2316, and the second socket portion 2313 of multiple connecting pieces is welded to form at least one weld 2316, so that adjacent connecting pieces are fixedly connected to form a linkage 231.

[0118] In other embodiments, the linkage 231 can also be other structures, as long as it can realize the rotation of the first connector 234 and the second connector 235. This application does not limit the specific structure of the linkage 231.

[0119] The following describes in detail the installation of the first connector on the support and the installation of the second connector on the base.

[0120] Please refer to Figures 22-25. Figure 22 is a structural schematic diagram of the connection between the base and the second connecting member; Figure 23 is a partial enlarged view of part III in Figure 22; Figure 24 is a partial enlarged view of the base in Figure 23; and Figure 25 is a structural schematic diagram of the cooperation between the base, the linkage, and the rotating shaft. As shown in Figure 22, the base 22 is equipped with a magnetic component 221. When the support assembly is in the retracted state, the magnetic component 221 is used to magnetically attract and cooperate with the magnetic material on the support component 21, thereby improving the reliability of the support assembly in the retracted state.

[0121] As shown in Figures 23 and 24, the base 22 has a first receiving portion 222, a second receiving portion 223, and a third receiving portion 224. The third receiving portion 224 is located between and communicates with the first receiving portion 222 and the second receiving portion 223. The base 22 also has a first mounting groove 225, the shape of which matches the shape of the second connector 235, allowing the second connector 235 to be inserted into the first mounting groove 225. The bottom wall of the first mounting groove 225 has one or more first mounting posts 226. The second connector 234 has a first fixing hole 2354, which is fixedly connected to the first mounting post 226, thereby fixing the second connector 235 to the base 22, improving the stability of the connection between the second connector 235 and the base 22, and reducing the possibility of them detaching.

[0122] Additionally, as shown in FIG23, after the second connector 235 is installed on the base 22, the second sleeve portion 2351 of the second connector 235 and the second rotating shaft 233 sleeved with 2351 are housed in the second receiving portion 223.

[0123] As shown in Figure 25, which is a view of Figures 23 and 24 taken from the other side along the thickness direction of the base, the second receiving portion 223 of the base 22 is also used to receive the second sleeve portion 2313 that is sleeved on the second rotating shaft 233. When the bracket assembly 2 is in the retracted state, part or all of the first rotating shaft 232 connected to the first connector 234 is housed in the first receiving portion 222, and the first sleeve portion 2312 of the linkage 231 is sleeved on the first rotating shaft 232 and is housed in part or all of the first receiving portion 222. Part or all of the first body portion 2311 connecting the first sleeve portion 2312 and the second sleeve portion 2313 is housed in the third receiving portion 224. The third receiving portion 224 can limit the linkage 231 to improve the stability of the linkage 231 in the retracted state and reduce the possibility of the linkage 231 shaking. At the same time, the third receiving portion 224 also provides space for the linkage 231 to be housed, so as to reduce the overall thickness of the bracket assembly 2.

[0124] Please continue to refer to Figures 26-28. Figure 26 is a structural schematic diagram of the connection between the support member and the first connecting member; Figure 27 is a partial enlarged view of part IV in Figure 26; Figure 28 is a partial enlarged view of the support member in Figure 27.

[0125] As shown in Figure 28, the support member 21 is provided with a fourth receiving portion 212 and a fifth receiving portion 213. When the bracket assembly 2 is in the retracted state, the fourth receiving portion 212 communicates with the first receiving portion 222 and forms a first receiving cavity. The first receiving cavity is used to accommodate the first rotating shaft 232 in the retracted state, as well as the first sleeve portion 2312 and the first bushing portion 2341 sleeved on the first rotating shaft 232. When the bracket assembly 2 is in the retracted state, the fifth receiving portion 213 communicates with the second receiving portion 223 and forms a second receiving cavity. The second receiving cavity is used to accommodate the second rotating shaft 233 in the retracted state, as well as the second sleeve portion 2313 and the second bushing portion 2351 sleeved on the second rotating shaft 233.

[0126] When both the support member 21 and the base 22 are provided with receiving portions to accommodate the first rotating shaft 232, the first sleeve portion 2312 and the first bushing portion 2341 sleeved on the first rotating shaft 232, the second rotating shaft 233, and the second sleeve portion 2313 and the second bushing portion 2351 sleeved on the second rotating shaft 233, the space between the support member 21 and the base 22 can be reasonably utilized without causing the thickness of the bracket assembly 2 to increase.

[0127] In one specific embodiment, the first receiving portion 222, the second receiving portion 223, and the third receiving portion 224 can specifically be through holes penetrating the base 22 along the thickness direction, or they can also be grooves. The fourth receiving portion 212 and the fifth receiving portion 213 can specifically be through holes penetrating the support member 21 along the thickness direction, or they can also be grooves.

[0128] Additionally, referring to Figures 27 and 28, the support member 21 is also provided with a second mounting groove 214. The shape of the second mounting groove 214 matches the shape of the first connector 234, allowing the first connector 234 to be embedded in the second mounting groove 214. One or more second mounting posts 215 are provided on the bottom wall of the second mounting groove 214. The first connector 234 has a second fixing hole 2344, which is fixedly connected to the second mounting post 215, thereby fixing the first connector 234 and the support member 21 together. This improves the stability of the connection between the first connector 234 and the support member 21 and reduces the possibility of them detaching from each other.

[0129] Please refer to Figure 29, which is a simplified schematic diagram of the main receiving groove and the support assembly. As shown in Figure 29, during the rotation of the support member 21 from the retracted state to the supported state, the first end 211 of the support member 21 abuts against the first sidewall 112 of the receiving groove 11. At this time, the position where the first end 211 abuts against the first sidewall 112 can serve as a fulcrum, allowing the support member 21 to continue rotating around this fulcrum and driving the first end 211 of the support member 21 away from the first sidewall 112, until it rotates from the state shown in Figure 29 to the fully open state. During this process, the position where the first end 211 of the support member 21 abuts against the first sidewall 112 promotes the continued rotation of the support member 21 without obstructing its rotation, allowing the support member 21 to be in the fully open state.

[0130] Specifically, as shown in Figure 29, when the included angle between the support member 21 and the bottom wall 111 of the receiving groove 11 is the third included angle θ1, the first end 211 of the support member 21 abuts against the first side wall 112 of the receiving groove 11. This third included angle θ1 satisfies: 25°≤θ1≤45°. That is to say, when the opening angle of the support member 21 reaches the third included angle θ1, the first end 211 of the support member 21 will abut against the first side wall 112. After abutting, the support member 21 can continue to rotate, so that the included angle between the support member 21 and the bottom wall 111 continues to increase.

[0131] For example, the third included angle θ1 can be 25°, 30°, 32°, 35°, 40°, 43°, 45°, etc.

[0132] In one specific embodiment, a buffer layer (not shown in the figure) may be provided on the first sidewall 112 of the receiving groove 11. When the first end 211 abuts against the first sidewall 112 during the rotation of the support member 21, the first end 211 contacts the buffer layer, which can play a buffering role, reduce the noise when the first end 211 abuts against the first sidewall 112, and reduce the wear of the first end 211 and the first sidewall 112.

[0133] The specific material of the buffer layer can be any commonly used buffer material in the field. This application does not limit the material and structure of the buffer layer.

[0134] The above descriptions are merely specific implementations of the embodiments of this application, but the protection scope of the embodiments of this application is not limited thereto. 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.
