Description

Technical Field

[0001] The utility model relates to the technical field of 3C digital accessories, in particular to a bracket component and an electronic equipment accessory. Background Art

[0002] When using electronic devices such as mobile phones and tablets, they are usually equipped with a bracket assembly to obtain a supporting angle. In the related technology of a protective case with a bracket, the bracket is usually set in a recessed receiving groove of the protective case to ensure that the surface of the bracket is flush with the surface of the protective case, thereby avoiding the protrusion of the bracket and affecting user use.

[0003] In the technology of related unlocking bracket protective shells, the bracket is locked or released through a locking structure. When the locking structure unlocks the bracket, it must be ensured that there is no damping rotation between the bracket and the protective shell (or the damping force is very small), otherwise the bracket will be difficult to escape from the receiving slot when unlocked. Therefore, the traditional unlocking bracket protective shell can only be opened to a maximum angle when the bracket is opened (that is, the angle when the bracket is opened to a certain angle and abuts against the protective shell). It is precisely because there is no damping between the bracket and the protective shell that this product cannot meet the different angle adjustments of the bracket.

[0004] Therefore, it is necessary to design a product that can satisfy the requirements that the bracket can be opened by locking / unlocking, and can also satisfy the requirements that the bracket can adjust different supporting angles. Utility Model Content

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0043] In order to enable those skilled in the art to better understand the technical solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the utility model.

[0044] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0045] It should also be noted that the division of multiple embodiments in the present invention is only for the convenience of description and should not constitute a special limitation. The features in various embodiments can be combined and referenced to each other without contradiction.

[0046] Reference Figure 1 The embodiment of the utility model provides a bracket assembly 10, comprising: a base 11, a support structure 12 and a rotating shaft structure 13. The rotating shaft structure 13 is rotatably connected to the base 11. The support structure 12 is rotatably connected to the rotating shaft structure 13. The support structure 12 has a first angle position, a preset angle position and a second angle position relative to the base 11. The support structure 12 can be locked at the first angle position or unlocked at the first angle position. The support structure 12 can rotate from the first angle position to the preset angle position as the rotating shaft structure 13 rotates relative to the base 11 synchronously. And the support structure 12 can rotate relative to the rotating shaft structure 13 and rotate from the preset angle position to the second angle position. In the process of the support structure rotating from the preset angle position to the second angle position, the rotating shaft structure 13 can stop rotating with the base 11. The rotational friction between the rotating shaft structure 13 and the base 11 is smaller than the rotational friction between the rotating shaft structure 13 and the supporting structure 12, wherein the rotational friction can also be understood as a damping force, that is, the rotating shaft structure 13 is easier to rotate relative to the base 11, and more difficult to rotate relative to the supporting structure 12. When the rotating shaft structure 13 rotates relative to the base 11, the supporting structure 12 can first be stationary relative to the rotating shaft structure 13, so as to rotate synchronously with the rotating shaft structure 13. When the rotating shaft structure 13 stops rotating with the base 11, the supporting structure 12 rotates relative to the rotating shaft structure 13.

[0047] For example, the bracket assembly 10 further includes a locking structure 113, which is used to lock or unlock the support structure 12 at the first angle position. The locking structure 113 can lock the support structure 12 at the first angle position by, for example, magnetic attraction, snap connection, etc. When the support structure 12 needs to be opened for use, the support structure 12 can be unlocked from the first angle position by releasing the magnetic attraction or releasing the snap connection.

[0048] For example, the angle between the support structure 12 and the base 11 at the first angle position is smaller than the angle between the support structure 12 and the base 11 at the preset angle position, and the angle between the support structure 12 and the base 11 at the second angle position is greater than the angle between the support structure and the base 11 at the preset angle position.

[0049] When the bracket assembly 10 is used, when the support structure 12 is in a closed state, the support structure 12 is stored on the base 11, for example, the support structure 12 is stacked on the base 11, and at this time, it can be considered that the angle between the support structure 12 and the base 11 is 0, and the support structure 12 is at the first angle position. That is, the support structure 12 is in a stored state at the first angle position. The locking structure 113 is locked with the support structure 12. When the bracket assembly 10 needs to be used, the support structure 12 can be rotated from the first angle position to the preset angle position, for example, by rotating with the rotating shaft structure 13 relative to the base 11.

[0050] In some embodiments, the bracket assembly 10 includes, for example, a pop-up structure 14, which is used to make the support structure 12 pop up from the first angle position to the preset angle position when the support structure 12 is unlocked from the first angle position. For example, when the support structure 12 is stored on the base 11, the pop-up structure 14 is in a compressed state, and the preset angle position is the position of the shaft structure 13 after the pop-up structure 14 is completely released. In the process of the shaft structure 13 rotating to the preset angle position under the elastic action of the pop-up structure 14, the support structure 12 is also driven to rotate synchronously to realize the pop-up of the support structure 12, so that the support structure 12 switches from the storage state to the open state, and the support effect can be achieved. In some embodiments, the pop-up structure 14 may not be provided, and the user manually opens the support structure 12 and rotates it from the first position to the preset angle position to switch from the storage state to the open state, and then bends the support structure 12 to continue to rotate from the preset angle position to obtain a suitable support angle (i.e., the second angle position). In the process of the support structure 12 rotating from the preset angle position to the second angle position, for example, a limiting structure can be set to enable the rotating shaft structure 13 to stop rotating with the base 11, or the user can directly press the rotating shaft structure 13 with his hand to stop the rotating shaft structure 13 from rotating with the base 11.

[0051] In the bracket assembly of the related art, in order to reduce the damping force between the rotating shaft and the bracket, it is usually necessary to set a limit part on the bracket to abut against a specific part (such as the shell of the protective shell) after the bracket is ejected to achieve the bracket to remain at a specific angle. Therefore, this bracket can only be supported at this specific angle and cannot achieve multi-angle support. In the bracket assembly 10 provided by the embodiment of the utility model, the support structure 12 can be limitedly rotated relative to the base 11 through the rotating shaft structure 13, and the support structure 12 can rotate relative to the rotating shaft structure 13, which can achieve a multi-angle adjustment effect, and thus has more support angles than traditional brackets.

[0052] In some embodiments, reference Figures 1 to 12, the rotating shaft structure 13 includes, for example, a first rotating shaft assembly, the first rotating shaft assembly includes a first rotating shaft 131, the first rotating shaft 131 is rotatably connected to the base 11, and the support structure 12 is connected to the first rotating shaft 131 in a damped rotation. In this way, the support structure 12 and the rotating shaft structure 13 are relatively stationary during the process of the rotating shaft structure 13 rotating from the first angle position to the preset angle position, and the support structure 12 can also be rotatably connected to the rotating shaft structure 13, so after the spring is opened, the support structure 12 can still be operated to rotate around the rotating shaft structure 13. At this time, the rotating shaft structure 13 is stationary relative to the base 11, and the angle of the support structure 12 relative to the base 11 changes, so that the angle adjustment function can be achieved. In some embodiments, for example, the support structure 12 and the rotating shaft structure 13 are damped in rotation, and the support structure 12, for example, has a second sleeve, and the first rotating shaft 131 is penetrated by the second sleeve, and the diameter of the shaft hole of the second sleeve is smaller than the diameter of the first rotating shaft 131, so as to achieve a damped rotation connection.

[0053] In some embodiments, reference Figure 3 The first rotating shaft assembly includes a first rotating shaft 131 and a pushing member 132 fixedly connected to the first rotating shaft 131, and the pushing member 132 is located between the supporting structure 12 and the base 11. The supporting structure 12 is rotatably connected to the first rotating shaft 131. The pushing member 132 can push the supporting structure 12 to rotate from the first angle position to the preset angle position as the first rotating shaft 131 rotates relative to the base 11. For example, in the process of the supporting structure 12 rotating from the first angle position to the preset angle position, the pushing member 132 abuts against the supporting structure 12, thereby pushing the supporting structure 12 to open. After the supporting structure 12 reaches the preset angle position, the supporting structure 12 can be manually adjusted to rotate relative to the rotating shaft structure 13 to achieve support at other angles.

[0054] In some embodiments, a first stop portion 111 is disposed on one of the base 11 and the first rotating shaft assembly, and a stop member 133 is disposed on the other of the base 11 and the first rotating shaft assembly. The stop member 133 is located on the side of the first stop portion 111 facing away from the support structure 12. The distance between the stop member 133 and the first stop portion 111 can decrease as the support structure 12 rotates from the first angular position to the preset angular position, and the support structure 12 reaches the preset angular position when the stop member 133 abuts against the first stop portion 111. Figure 5 and Figure 6 As shown, the stopper 133 is arranged on the first rotating shaft assembly, and the first stopper 111 is arranged on the base 11. At the first angular position, the stopper 133 is at a certain distance from the first stopper 111. When the rotating shaft structure 13 (the first rotating shaft 131) is in accordance with Figure 6 When the stop member 133 rotates counterclockwise in the direction of the first stop portion 111, the distance between the stop member 133 and the first stop portion 111 is reduced. Figure 7When the first rotating shaft 131 rotates until the stop member 133 abuts against the first stop portion 111, the first rotating shaft 131 is blocked by the first stop portion 111 so that the first rotating shaft 131 cannot continue to rotate counterclockwise to reach the preset angle position. Figure 8 , the first rotating shaft 131 in the first rotating shaft assembly does not continue to rotate, and the support structure 12 can continue to rotate around the rotating shaft structure 13 to an angle greater than the preset angle position to meet the user's support needs. Or refer to Fig.13 and Fig.14 The stopper 133 is arranged on the base 11, and the first stopper 111 is arranged on the first shaft assembly. When the shaft structure 13 is arranged according to Fig.14 When the position shown is rotated clockwise, the first stop portion 111 rotates closer to the stop member 133 , so that the distance between the stop member 133 and the first stop portion 111 is reduced. Fig.13 and Fig.14 The state shown is that the support structure 12 reaches a preset angle position.

[0055] Furthermore, in some embodiments, a second stopper 112 is also provided, and the second stopper 112 and the first stopper 111 are both provided on the base 11 or the first shaft assembly. In other words, when the first stopper 111 is provided on the base 11, the second stopper 112 is also provided on the base 11; when the first stopper 111 is provided on the first shaft assembly, the second stopper 112 is also provided on the first shaft assembly. The stopper 133 is located between the first stopper 111 and the second stopper 112. Figure 6 In the position shown, the second stop portion 112 is located below the stop member 133. Figure 8 When the support structure 12 needs to be stored in the position shown in the figure, the support structure 12 and the shaft structure 13 are relatively stationary, the support structure 12 is rotated close to the base 11, and the shaft structure 13 is rotated according to the Figure 6 Rotating clockwise in the orientation shown, the stop member 133 approaches the second stop portion 112. When the stop member 133 rotates to abut against the second stop portion 112, the shaft structure 13 cannot continue to rotate. If the support structure 12 has not been completely stored in the base 11 at this time, the support structure 12 can continue to be rotated so that the support structure 12 rotates relative to the shaft structure 13 and is finally stored on the base 11.

[0056] Among them, the rotating shaft structure 13 specifically includes, for example, a first sleeve 134, and the first rotating shaft 131 is penetrated by the first sleeve 134 and fixedly connected to the first sleeve 134. The pushing member 132 and the stop member 133 (or the first stop portion 111) described in the aforementioned embodiment are, for example, formed on the first sleeve 134. For example, the first sleeve 134 includes two arranged in the axial direction of the first rotating shaft 131, the stop members 133 protrude from the two first sleeves 134 respectively, and the pushing member 132 is connected between the two first sleeves 134. In other embodiments, the stop member 133 may also protrude outwardly relative to the surface of the first rotating shaft 131 along the radial direction of the first rotating shaft 131, that is, the stop member 133 is a part protruding from the first rotating shaft 131, and does not need to be set through the first sleeve 134. For another example, referring to Figure 4 A groove structure is formed on the first sleeve 134 , and two opposite sides of the groove structure serve as a first stop portion 111 and a second stop portion 112 , respectively. The stop member 133 is disposed on the base 11 .

[0057] The aforementioned pop-up structure 14 is specifically a torsion spring, which can be sleeved on the first rotating shaft 131. For example, when there are two first sleeves 134 and the two first sleeves 134 are spaced apart along the axial direction of the first rotating shaft 131, the pop-up structure 14 is located between the two first sleeves 134, so the two first sleeves 134 can also limit the pop-up structure 14 to prevent the pop-up structure 14 from sliding along the first rotating shaft 131.

[0058] In some embodiments, referring to the specific structure in the above-mentioned embodiments, when the support structure 12 is in the storage state, the torsion spring is in a compressed state, and the angle between the first pin and the second pin is small. When the torsion spring is opened, the angle between the first pin and the second pin becomes larger, and the second pin pushes the pusher 132, and the pusher 132 pushes the support structure 12 to realize the opening of the support structure 12. Specifically, the first pin of the torsion spring is fixed on the base 11, and the second pin is fixed on the shaft structure 13 (specifically the pusher 132). When the torsion spring is in a fully released state after the torsion spring is opened, the second pin no longer pushes the pusher 132. At this time, the shaft structure 13 reaches a preset angle position. When the support structure 12 continues to be manually rotated, the pusher 132 in the shaft structure 13 cannot continue to rotate because it is fixed by the torsion spring. Therefore, the support structure 12 can rotate relative to the shaft structure 13 to achieve support at other angles. By using a torsion spring to limit the rotation angle of the first rotating shaft 131 , the stopper 133 and the first stopper 111 can be replaced to limit the preset angle position of the supporting structure 12 .

[0059] In some embodiments, reference Figure 4The support structure 12 includes a support member 121 and a first connecting member 122, and the first connecting member 122 is rotatably connected to the rotating shaft structure 13. A first limiting portion 1221 is provided on the first connecting member 122, and a second limiting portion 1211 is provided on the support member 121, and the first limiting portion 1221 and the second limiting portion 1211 are slidably connected. The support member 121 can be engaged with or separated from the locking structure 113 as the second limiting portion 1211 slides relative to the first limiting portion 1221, so that the support member 121 is locked or unlocked at the first angular position. That is, when the support member 121 is engaged with the locking structure 113, the support member 121 is locked at the first angular position, and when the support member 121 is separated from the locking structure 113, the support member 121 is unlocked from the first angular position.

[0060] The first limiting portion 1221 and the second limiting portion 1211 can be, for example, a sliding connection between a slider and a slide rail, or can be other sliding connection forms such as a sliding connection between a slider and a slide groove. When using the bracket assembly 10, after the support member 121 is rotated with the first connecting member 122 to a state of being stacked with the base 11, the support member 121 can be manually pushed to slide relative to the first connecting member 122, and engage with the locking structure 113 to lock the support member 121 on the base 11. When it is necessary to open the support structure 12 to realize the supporting function, push the support member 121 to slide relative to the first connecting member 122 (opposite to the sliding direction when stored), so that the support member 121 is separated from the locking structure 113, and then the support structure 12 is ejected as a whole under the elastic action of the ejection structure 14 to achieve unlocking. The position of the locking structure 113 can be, for example, as shown in the figure. Figure 2 As shown, it is arranged at an end of the base 11 away from the rotating shaft structure 13, but it can certainly be arranged at other positions.

[0061] In some embodiments, one of the first limiting portion 1221 and the second limiting portion 1211 is a sliding groove, and the other of the first limiting portion 1221 and the second limiting portion 1211 is a sliding block. Figure 4 The first limiting portion 1221 is a sliding block, and the second limiting portion 1211 is a sliding groove.

[0062] The sliding distance of the slider in the slide groove is greater than the engagement depth between the support member 121 and the locking structure 113. Fig. 9 and Fig.10 The sliding distance of the slider in the slide groove is L1, which can also be understood as the length of the slide groove minus the length of the slider. The engagement depth between the support member 121 and the locking structure 113 is L2, and L1 is greater than or equal to L2. Fig. 9 The figure shows the state where the support member 121 is engaged with the locking structure 113. Fig. 9In the position shown, when the distance of sliding the support member 121 to the left is greater than L2, the engagement state between the locking structure 113 and the support member 121 can be released. Therefore, designing L1 to be greater than L2 can ensure that the support member 121 is normally unlocked.

[0063] In some embodiments, an elastic reset structure 15 is further included, one side of the elastic reset structure 15 is connected to the support member 121, and the other side of the elastic reset structure 15 is connected to the first connection member 122. The elastic reset structure 15 is, for example, a torsion spring, with both ends fixed to the support member 121 and the first connection member 122, respectively. Fig. 9 When the support member 121 is rotated close to the base 11 for storage, when the support member 121 is rotated to be flush with the upper surface of the locking structure 113, the support member 121 is further pressed downward to compress the elastic reset structure 15, so that the support member 121 moves to the upper surface of the locking structure 113. Fig. 9 The support member 121 can be locked in the slot below the locking structure 113 by sliding to the left side of the support member 121, and the elastic reset structure 15 can be restored to its elasticity after the user lets go, so that the support member 121 is kept in the state of being locked with the locking structure 113 without being separated at will. When unlocking is required, the support member 121 can be manually pushed to overcome the elastic force of the elastic reset structure 15 to unlock the support member 121 from the locking structure 113.

[0064] Reference Fig.10 In some embodiments, a boss 1212 is formed on one side of the support member 121 close to the first connection member 122, the second limiting portion 1211 is disposed on the boss 1212, and the first connection member 122 is mounted on the boss 1212 to form a preset gap with the support member 121. Fig.10 As shown, the lower surface of the support member 121, except for the boss 1212, forms a preset gap with the upper surface bracket of the first connecting member 122. In the process of assembling the bracket assembly 10, the support member 121 and the first connecting member 122 can usually be combined together by riveting, so that pressure is applied to the first connecting member 122. The preset gap formed by the arrangement of the boss 1212 can prevent the first connecting member 122 from being deformed during the installation process.

[0065] In some embodiments, reference Figure 15 to Figure 18In another embodiment of the utility model, the bracket assembly 10 also includes a fixed portion fixedly connected to the base 11, and the shaft structure 13 includes a rotating portion and a second rotating shaft assembly, the rotating portion can be rotatably connected to the base 11, and the second rotating shaft assembly is connected to the rotating portion. The support structure 12 is connected to the second rotating shaft assembly in a damping rotational connection, and the support structure 12 can rotate from a first angular position to a preset angular position as the second rotating shaft assembly and the rotating portion rotate synchronously relative to the fixed portion. The support structure 12 can rotate relative to the second rotating shaft assembly to rotate from a preset angular position to a second angular position. Among them, one of the fixed portion and the rotating portion is a first rotating shaft 131, and the other of the fixed portion and the rotating portion is a first shaft sleeve 134 and is rotatably connected to the first shaft sleeve 134.

[0067] Specifically, the shaft connector 136, the second shaft 135 and the support structure 12 can rotate synchronously around the first shaft 131 to realize the rotation of the second shaft assembly and the rotating part around the fixed part, and the support structure 12 rotates from the first angle position to the preset angle position. The support structure 12 can rotate with damping around the second shaft 135, so that after the support structure 12 reaches the maximum preset angle position, it can continue to rotate to the second angle position to adjust the support angle.

[0068] In this embodiment, the dual-axis structure of the first axis 131 and the second axis 135 enables the first axis 131 to enable the support structure 12 to rotate from a first position to a preset angle position and switch from a storage state to an open state, and the second axis 135 can enable the support structure 12 to rotate from a preset angle position to a second angle position to adjust the support angle.

Specifically, the stopper 133 is arranged on one of the fixed part and the second shaft assembly, and the first stopper 111 is arranged on the other of the fixed part and the second shaft assembly. More specifically, Fig.18The stopper 133 shown in the figure is arranged on the first sleeve 134 (the fixed part is the first sleeve 134 in this case), and the first stopper 111 is arranged on the shaft connecting member 136. The maximum rotation angle of the second shaft assembly relative to the first shaft assembly can be limited by the first stopper 111. Similarly, the second stopper 112 can be arranged on the shaft connecting member 136 to further limit the rotation of the second shaft assembly. The functions and implementation principles of the stopper 133, the first stopper 111 and the second stopper 112 can be referred to. Figures 6 to 8 The principles of the stopper 133, the first stopper portion 111 and the second stopper portion 112 are not described in detail here.
