[0024] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is 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 this application and are not intended to limit this application.

[0025] The present application provides a bracket assembly and a mobile phone case to solve the problem in the related art that electronic devices with brackets can usually only be placed on the desktop at a fixed angle, the placement angle of the electronic device cannot be adjusted, and cannot well meet customer needs.

[0026] In a first aspect, the present application provides a bracket assembly, such as Figures 1 to 3As shown, the bracket assembly includes a connecting bracket 10 , a first bracket 20 and a second bracket 30 . It should be noted that the bracket assembly can be applied to electronic devices such as mobile phones, the connecting frame 10 is used to connect to the electronic device, and the first bracket 20 and the second bracket 30 are used to provide support for the electronic device; the bracket assembly can provide support for the electronic device alone. After placing the bracket assembly on the back side of the electronic device, the connecting frame 10 can be directly connected to the housing of the electronic device through magnetic connection, bonding or other connection methods, and the first bracket 20 and the second bracket 30 can provide support for electronic devices of various types and sizes; the bracket assembly can also be used as part of a protective cover for the electronic device. When the protective cover is put on the electronic device, the connecting frame 10 is connected to the protective cover and provides support for the electronic device through the first bracket 20 and the second bracket 30; taking the application of the bracket assembly to a mobile phone as an example, the bracket assembly can be placed on the back side of the mobile phone, and the connecting frame 10 can be connected to the housing of the mobile phone or to the protective cover of the mobile phone case. When the mobile phone needs to be placed on the desktop at an angle, the first bracket 20 or / and the second bracket 30 are set at an angle to the mobile phone. The first bracket 20 or the second bracket 30 can be brought into contact with the desktop to provide support for the mobile phone, so that the mobile phone can be placed on the desktop stably at an angle.

[0027] Specifically, the first bracket 20 is rotatably connected to the connecting frame 10, and the first bracket 20 can rotate around the first axis XX relative to the first connecting member 12 to adjust the angle formed by the first bracket 20 and the connecting frame 10, and the extension direction of the first axis XX intersects with the thickness direction of the connecting frame 10; the second bracket 30 is rotatably connected to the first bracket 20, and the second bracket 30 can rotate around the second axis YY relative to the first bracket 20 to adjust the angle formed by the second bracket 30 and the first bracket 20, and the extension direction of the second axis YY intersects with the thickness direction of the connecting frame 10. Among them, the shape of the first bracket 20 and the second bracket 30 can be annular, square or irregular, etc., which can be selected according to actual conditions, and the embodiment of the present application does not specifically limit this; the extension direction of the first axis XX and the thickness direction of the connecting frame 10 can be perpendicular or form an angle of other angles, such as 30 degrees, 45 degrees, 60 degrees, 75 degrees or other angles; the extension direction of the second axis YY and the thickness direction of the connecting frame 10 can be perpendicular or form an angle of other angles, such as 30 degrees, 45 degrees, 60 degrees, 75 degrees or other angles; the second axis YY and the first axis XX can be parallel or intersecting.

[0028] It is understandable that when a bracket assembly is needed to provide support for the electronic device so that the electronic device can be stably placed on the desktop, the first bracket 20 can be rotated to contact the desktop to provide support for the electronic device. By adjusting the angle formed by the first bracket 20 and the connecting frame 10, the placement angle of the electronic device on the desktop can be adjusted. When the first bracket 20 is rotated, the second bracket 30 will be driven to rotate; or only the second bracket 30 can be rotated (such as Figure 2 ), the second bracket 30 is brought into contact with the desktop to provide support for the electronic device. By adjusting the angle formed by the second bracket 30 and the first bracket 20, the angle formed by the second bracket 30 and the electronic device can be adjusted, thereby adjusting the placement angle of the electronic device on the desktop; the first bracket 20 and the second bracket 30 can also be rotated (such as Figure 3 ), by adjusting the angle formed by the first bracket 20 and the connecting frame 10, and the angle formed by the second bracket 30 and the first bracket 20, the placement angle of the electronic device on the desktop can be adjusted, so that the electronic device can have more placement angles, which can better meet customer needs; in addition, when placing the electronic device, the angle formed by the second bracket 30 and the first bracket 20 can be adjusted so that the entire second bracket 30 is in contact with the desktop. Compared with only contacting the end of the first bracket 20 or the second bracket 30 with the desktop, the entire second bracket 30 is in contact with the desktop, so that the placement of the electronic device can be more stable and reliable.

[0029] In one embodiment, the second bracket 30 has a receiving groove 31 for receiving the first bracket 20. It is understandable that when the angle formed by the second bracket 30 and the first bracket 20 is 0 degrees, the first bracket 20 is accommodated in the receiving groove 31; when the angle formed by the second bracket 30 and the first bracket 20 is not 0 degrees but is relatively small, the first bracket 20 can be partially accommodated in the receiving groove 31, thereby reducing the overall volume and thickness of the bracket assembly, facilitating the storage and transportation of the bracket assembly. It should also be noted that the overall volume of the second bracket 30 is greater than the overall volume of the first bracket 20. Compared to contacting the first bracket 20 with the desktop to provide support for the electronic device, when the second bracket 30 is in contact with the desktop, the contact area of the second bracket 30 with the desktop is larger, making the placement of the electronic device more stable and reliable.

[0030] In one embodiment, the connecting frame 10 is provided with a receiving slot 11 for accommodating the first bracket 20 and the second bracket 30. The first bracket 20 and the second bracket 30 have an unfolded state (eg Figure 2 and Figure 3 ) and storage status (such as Figure 1It is understood that when the first bracket 20 and the second bracket 30 are not needed, the first bracket 20 and the second bracket 30 can be rotated so that the first bracket 20 and the second bracket 30 are in the storage state, and the first bracket 20 and the second bracket 30 are both stored in the storage slot 11 (such as Figure 1 ), at this time, the angles formed by the first bracket 20 and the second bracket 30 with the connecting frame 10 are both 0 degrees, making the bracket assembly easy to carry and place; when the first bracket 20 and the second bracket 30 need to be used, the first bracket 20 and the second bracket 30 can be rotated to move the first bracket 20 and the second bracket 30 out of the storage slot 11. At this time, the first bracket 20 and the second bracket 30 are in the expanded state, and the angles formed by the first bracket 20 and the second bracket 30 with the connecting frame 10 are both greater than 0 degrees.

[0031] In one embodiment, the second bracket 30 can rotate 360 degrees around the second axis YY relative to the first bracket 20, so that the electronic device can be placed at more angles.

[0032] like Figure 4 As shown, in one embodiment, the first bracket 20 is rotatably connected to the connecting frame 10 via a first rotating shaft 41, and the second bracket 30 is rotatably connected to the first bracket 20 via a second rotating shaft 42. It can be understood that the first axis XX is the axis centerline of the first rotating shaft 41, and the second axis YY is the axis centerline of the second rotating shaft 42.

[0033] The first end of the first rotating shaft 41 can be fixed to the connecting frame 10 by gluing or riveting, and the second end of the first rotating shaft 41 can be rotatably connected to the first bracket 20 via a metal member. An additional metal member is provided between the second end of the first rotating shaft 41 and the first bracket 20 to enhance the structural strength and rotational damping of the connection between the first rotating shaft 41 and the first bracket 20, thereby providing sufficient rotational damping for the first bracket 20 and imparting a certain degree of self-locking performance to the first bracket 20. This allows the first bracket 20 to provide stable support for the electronic device when the angle formed between the first bracket 20 and the connecting frame 10 is greater than 0 degrees. In one embodiment, the first rotating shaft 41 can be a metal rotating shaft made of copper, steel, aluminum, a copper alloy, or an aluminum alloy, thereby increasing the service life of the first rotating shaft 41. Metal rotating shafts also have better self-locking performance and provide greater rotational damping for the first bracket 20.

[0034] The second rotating shaft 42 can be a straight damping shaft. The first end of the second rotating shaft 42 is connected to the first bracket 20, and the second end of the second rotating shaft 42 is provided with a knurled pattern and connected to the second bracket 30. This provides sufficient rotational damping for the second bracket 30, giving the second bracket 30 a certain self-locking performance. When the angle formed by the second bracket 30 and the first bracket 20 is greater than 0 degrees, the second bracket 30 can also provide stable support for the electronic device. In one embodiment, the first rotating shaft 41 can also be a straight damping shaft.

[0035] In one embodiment, the first bracket 20 and the second bracket 30 do not form a closed conductor loop, which can prevent the first bracket 20 and the second bracket 30 from triggering the FOD (Foreign Object Detection) function of the electronic device, and prevent the triggering of the FOD function from causing the electronic device to be disconnected from charging, heating or overheating during the wireless charging process, thereby affecting the charging efficiency of the electronic device. The FOD function is a function used in wireless charging technology, which can be used to detect whether there is a metal object between the charger and the receiver. The specific working principle of FOD has long been disclosed in related technologies and will not be repeated in this application.

[0036] The first bracket 20 can be non-metallic to ensure that the first bracket 20 and the second bracket 30 do not form a closed conductor loop. The first bracket 20 can also be formed of both non-metal and metal. The main portion of the first bracket 20 is formed of non-metal. Metal materials can be used to locally reinforce locations such as the connection between the first bracket 20 and the connecting frame 10, the connection between the first bracket 20 and the second bracket 30, and the frequent bending points of the first bracket 20. The metal material should be located outside the area of the first bracket 20 corresponding to the wireless receiving coil of the electronic device. The second bracket 30 can be metal to ensure sufficient structural strength and prevent the entire second bracket 30 from shaking, thereby providing stable support for the electronic device.

[0037] like Figure 4 and Figure 5 As shown, in some embodiments of the present application, the connecting frame 10 includes a first connecting member 12 and a second connecting member 13. The second connecting member 13 is stacked with the first connecting member 12 and can rotate around a third axis ZZ relative to the first connecting member 12. The first bracket 20 is rotatably connected to the second connecting member 13, and the extension direction of the third axis ZZ is parallel to the thickness direction of the connecting frame 10.

[0038] It is understood that the second connecting member 13 and the first connecting member 12 can rotate relative to each other. When the second connecting member 13 rotates about the third axis ZZ, it drives the first bracket 20 and the second bracket 30 to rotate, thereby adjusting the relative position of the first bracket 20 and the second bracket 30 and the electronic device. The electronic device can be placed horizontally or vertically on the desktop to better meet customer needs. The shape of the first connecting member 12 can be disc-shaped, square, or irregular, etc., and can be selected according to actual conditions; the second connecting member 13 can be disc-shaped. In this case, the third axis ZZ is the axis of the second connecting member 13.

[0039] like Figures 4 to 7 As shown, in one embodiment, the bracket assembly further includes a rotational sound-generating assembly 50, which is located between the first connector 12 and the second connector 13. The rotational sound-generating assembly 50 includes a first mating member 51 and a second mating member 52. The first mating member 51 is disposed on one of the first connector 12 and the second connector 13, and the second mating member 52 is disposed on the other of the first connector 12 and the second connector 13. The second mating member 52 is configured to cooperate with the first mating member 51 to produce a sound when the second connector 13 rotates relative to the first connector 12. It is understood that when a user grasps the second connector 13 and rotates the second connector 13, the second mating member 52 and the first mating member 51 will cooperate to produce a sound during the rotation of the second connector 13, generating sound feedback. This can enhance user feedback and reduce the possibility of the second connector 13 rotating due to accidental touch, thereby improving the user experience.

[0040] In one embodiment, a placement groove 53 is provided on one of the first connecting member 12 and the second connecting member 13, and the first matching member 51 includes an elastic member provided in the placement groove 53, and the elastic member includes a protrusion 511 extending out of the placement groove 53; the second matching member 52 is provided on the other of the first connecting member 12 and the second connecting member 13, and the second matching member 52 is provided with a plurality of grooves 521 arranged at intervals along the circumference of the first connecting member 12 and the second connecting member 13, and the grooves 521 are used for inserting the protrusion 511. When the second connecting member 13 and the first connecting member 12 rotate relative to each other, the protrusion 511 collides with the second matching member 52 to make a sound. It can be understood that when the second connecting member 13 rotates, when it rotates to the position where the protrusion 511 is opposite to the groove 521, the protrusion 511 will be inserted into the groove 521. At this time, a greater force is used to rotate the second connecting member 13, so that the protrusion 511 moves out of the groove 521. In the process of the protrusion 511 entering and exiting the groove 521, it will collide with the second matching member 52 under the action of elastic force, thereby generating intermittent feedback sound, and allowing the user to feel obvious rotation resistance during the rotation of the second connecting member 13, which can provide customers with obvious tactile feedback, and further enhance the user's tactile feedback.

[0041] Specifically, the elastic member may also include a support arm 512 and an elastic arm 513. The elastic arm 513 is provided at both ends of the support arm 512, and the elastic arm 513 abuts against the bottom wall of the placement groove 53. The protrusion 511 is provided on the support arm 512. When the second connecting member 13 is rotated and the protrusion 511 is subjected to an external force, the elastic arm 513 is squeezed and deformed, thereby allowing the second connecting member 13 to rotate normally, preventing the second connecting member 13 from being stuck due to excessive rotational resistance. Exemplarily, the protrusion 511 is provided in the middle part of the support arm 512, and the elastic arm 513 is located at the opposite ends of the support arm 512, so that the elastic arm 513 can evenly disperse the force on the support arm 512, thereby extending the service life of the elastic body. In other embodiments, the first matching member 51 may also be a device such as an elastic striker or an elastic ball.

[0042] Specifically, the second mating piece 52 can be a tooth-like structure arranged around the first mating piece 51 and the second connecting piece 13. The groove 521 is a tooth groove on the second mating piece 52. When the second connecting piece 13 is in the state, the protrusion 511 rotates along the second mating piece 52 and enters and exits the mating groove, thereby generating intermittent feedback sound.

[0043] In some embodiments of the present application, a receiving space 121 is provided on the first connecting member 12 and passes through the first connecting member 12 , and a boss structure 122 is provided on the inner side wall of the receiving space 121 . The second connecting member 13 is located in the receiving space 121 and on one side of the boss structure 122 .

[0044] Among them, the connecting frame 10 also includes a third connecting member 14, which is located in the accommodating space 121 and on the other side of the boss structure 122. The third connecting member 14 is connected to the second connecting member 13, and a limiting groove 15 is defined between the third connecting member 14 and the second connecting member 13. The limiting groove 15 extends along the circumference of the accommodating space 121. The boss structure 122 is located in the limiting groove 15. The boss structure 122 can rotate along the limiting groove 15, so that the second connecting member 13 and the third connecting member 14 can rotate 360 degrees along the boss structure 122.

[0045] It should be noted that the accommodating space 121 can provide installation space for the second connecting member 13 and the third connecting member 14, making the overall bracket assembly thinner, and by setting the boss structure 122 and the limiting groove 15, the second connecting member 13 and the third connecting member 14 can be installed on the first connecting member 12 through the cooperation between the limiting groove 15 and the boss structure 122, and the boss structure 122 is clamped between the second connecting member 13 and the third connecting member 14, which can reduce the possibility of the second connecting member 13 and the third connecting member 14 falling off from the first connecting member 12, and the cooperation between the boss structure 122 and the limiting groove 15 makes the assembly of the bracket assembly simple.

[0046] Specifically, the first mating piece 51 is arranged on one of the side of the boss structure 122 close to the second connecting piece 13 and the side of the second connecting piece 13 close to the boss structure 122, and the second mating piece 52 is arranged on the other of the side of the boss structure 122 close to the second connecting piece 13 and the side of the second connecting piece 13 close to the boss structure 122.

[0047] like Figures 6 to 8 As shown, in one embodiment, a mounting groove 16 is provided on a side of the second connecting member 13 close to the third connecting member 14, and the mounting groove 16 extends along the circumference of the second connecting member 13. A connecting protrusion 17 is provided on a side of the third connecting member 14 close to the second connecting member 13, and the connecting protrusion 17 is inserted into the mounting groove 16 and connected to the second connecting member 13 to realize the connection between the second connecting member 13 and the third connecting member 14, so that the second connecting member 13 and the third connecting member 14 can rotate synchronously.

[0048] Furthermore, the connecting protrusion 17 and the mounting groove 16 are located inside the first fitting member 51 and the second fitting member 52 to prevent the first fitting member 51 and the second fitting member 52 from affecting the connection between the connecting protrusion 17 and the mounting groove 16 .

[0049] like Figure 9 As shown, the side surface of the second connecting member 13 away from the boss structure 122 is located within the accommodation space 121. It is understandable that the entire second connecting member 13 is hidden within the accommodation space 121. When the bracket assembly is used in an electronic device, the side surface of the second connecting member 13 away from the boss structure 122 faces the electronic device, while the side surface of the second connecting member 13 away from the boss structure 122 is hidden within the accommodation space 121. This can prevent the second connecting member 13 from rubbing against the electronic device during rotation, thereby preventing damage to the electronic device.

[0050] In one embodiment, if Figure 1 As shown, the first connecting member 12 is further provided with a light-transmitting opening 123 located on the side of the accommodation space 121, the second connecting member 13 is located in the accommodation space 121, and a handle portion 32 is provided on the side of the second bracket 30 away from the light-transmitting opening 123. It is understandable that the user can rotate the second bracket 30 by holding the handle portion 32, making the rotation of the second bracket 30 more convenient, as shown in FIG. Figure 10As shown, when the bracket assembly is applied to an electronic device, the light-transmitting opening 123 is an opening for the camera on the electronic device to extend out, and light can enter the camera through the light-transmitting opening 123. Since the thickness of the camera is usually large, a protruding step-like structure 63 is usually provided around the light-transmitting opening 123 to hide and protect the camera. In this embodiment, by arranging the handle portion 32 on the side of the second bracket 30 away from the light-transmitting opening 123, there is a sufficient distance between the handle portion 32 and the step-like structure 63 to prevent the gap between the handle portion 32 and the step-like structure 63 from being too small, making it difficult for the fingers to operate the handle portion 32.

[0051] In one embodiment, a magnetic attraction component (not shown in the figure) is provided on the first bracket 20 and / or the second bracket 30. The first bracket 20 and / or the second bracket 30 can be magnetically attracted to the connecting frame 10 or the housing of the electronic device through the magnetic attraction component to fix the first bracket 20 and the second bracket 30. When the electronic device is wirelessly charged, it can also be magnetically attracted to the wireless charging device through the magnetic attraction component, so that the electronic device is fixed on the wireless charging device.

[0052] On the second aspect, based on the above-mentioned bracket assembly, the present application also provides a mobile phone case, which includes a shell 60 and a bracket assembly as in any one of the above-mentioned embodiments, and the connecting frame 10 is connected to the shell 60.

[0053] Specifically, the housing 60 may include a back plate 61 and a frame 62 disposed around the back plate 61 , and the first connector 12 may be reused as the back plate 61 , that is, the first connector 12 may be reused as a part of the housing 60 .

[0054] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
