[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] After long-term research, the inventors have found that in life, people often need to use various electronic products, and many electronic products need to be supported by brackets for easy use. For example, a mobile phone or a tablet computer is supported by a bracket, which is convenient for users to watch its screen. At present, when the bracket supports the supported device in the prior art, it is not convenient to adjust the posture of the supported device, which has an adverse effect on the user's experience. In order to solve this technical problem, the present application provides the following embodiments.

[0018] like Figures 1 to 3 As shown, the bracket device 1 described in the embodiment of the bracket device of the present application includes a support mechanism 200, a first shell 110, a second shell 120 and a magnetic attraction component 130. The second shell 120 is rotatably connected to the first shell 110, and the second shell 120 is rotatable relative to the first shell 110 around the first reference axis L1. The magnetic attraction component 130 is connected to the second shell 120 or the first shell 110. The magnetic attraction component 130 is used to limit the supported device to the second shell 120 by magnetic force, so that the supported device can rotate relative to the first shell 110 around the first reference axis L1 together with the second shell 120. The support mechanism 200 is rotatably connected to the first shell 110, and the second shell 120 and the first shell 110 are rotatable relative to the support mechanism 200 around the second reference axis L2. The extension direction of the first reference axis L1 intersects with the extension direction of the second reference axis L2. That is, the first reference axis L1 is the rotation axis of the second housing 120 relative to the first housing 110 , and the second reference axis L2 is the rotation axis of the first housing 110 relative to the supporting mechanism 200 .

[0019] In some embodiments, the second shell 120 has a cylindrical outer surface, and the first reference axis L1 is located at a central axis position of the outer surface of the second shell 120 .

[0020] In some embodiments, the second housing 120 has a flat supporting area for placing the device to be supported, and the second reference axis L2 is arranged parallel to the supporting area.

[0021] Further, the extension direction of the first reference axis L1 is perpendicular to the extension direction of the second reference axis L2.

[0022] Specifically, the support mechanism 200 can be used to support the first shell 110. The second shell 120 is rotatably connected to the first shell 110, and is surrounded by the first shell 110 to form a receiving space 160, and the second shell 120 is rotatable along the circumferential direction D1 of the first shell 110. The magnetic attraction component 130 is located in the receiving space 160 and is connected to the second shell 120 or the first shell 110. The magnetic attraction component 130 is used to adsorb the supported device to the second shell 120, so that the supported device can rotate relative to the first shell 110 along the circumferential direction D1 of the first shell 110 together with the second shell 120. The magnetic attraction component 130 is used to adsorb the supported device to the side of the second shell 120 that is away from the receiving space 160.

[0023] By forming the accommodating space 160 , the second shell 120 and the first shell 110 can protect and shield the magnetic attraction component 130 , which is beneficial to improving the structural stability and aesthetics of the bracket device 1 .

[0024] By using the support mechanism 200 to support the first housing 110 and the second housing 120, it is beneficial for the second housing 120 to maintain its own posture stability in the process of carrying the supported device. Further, the support mechanism 200 can be used to raise the first housing 110 and the second housing 120, so that the first housing 110 and the second housing 120 and the supported device are spaced from the placement surface of the bracket device 1, which facilitates the second housing 120 and the supported device to rotate relative to the first housing 110.

[0025] The supported device sometimes needs to adjust its posture when being supported. For example, the supported device may be a mobile phone or a tablet computer. By rotating the supported device relative to the first housing 110, the posture of the mobile phone or tablet computer display screen can be adjusted, so that the mobile phone or tablet computer can switch between the horizontal and vertical screens. For another example, the supported device may be a mobile phone or a tablet computer. By rotating the supported device relative to the first housing 110, a crooked mobile phone or tablet computer can be straightened.

[0026] By setting the second shell 120 and the first shell 110 as a rotational connection, when the user adjusts the posture of the supported device along the circumferential direction D1 of the first shell 110, the second shell 120 and the supported device can rotate synchronously, so that there is no sliding friction between the second shell 120 and the supported device, or the sliding friction between the second shell 120 and the supported device can be reduced, which is beneficial to improve the rotation smoothness of the supported device and enhance the user feel.

[0027] By setting the support mechanism 200 and the first housing 110 to be rotatably connected, the freedom of movement of the second housing 120 can be increased, thereby increasing the freedom of movement of the supported device, and facilitating the adjustment of the posture of the supported device. Furthermore, when the bracket device 1 is working, the second reference axis L2 is parallel or approximately parallel to the horizontal plane, so that the pitch angle of the supported device can be adjusted. For example, when the supported device is a mobile phone or a tablet computer, by adjusting the pitch angle of the mobile phone or the tablet computer, it is convenient for the user to watch the mobile phone or the tablet computer.

[0028] Optionally, the magnetic attraction component 130 includes magnets arranged in an annular shape. In some embodiments, the magnetic attraction component 130 may include an electromagnet.

[0029] Alternatively, if Figure 2 and Figure 3 As shown, the magnetic attraction assembly 130 includes a plurality of magnets arranged along the circumferential direction D1 of the first housing 110. Furthermore, the plurality of magnets are spliced ​​to form a ring structure with a break, which is convenient for installation and meets the installation specifications.

[0030] Alternatively, if Figure 1 , Figures 2 to 5 As shown, the magnetic attraction component 130 is connected to the second shell 120, so that the supported device, the magnetic attraction component 130, and the second shell 120 can rotate together around the first reference axis L1 relative to the first shell 110. Further, the supported device, the magnetic attraction component 130, and the second shell 120 can rotate together along the circumferential direction D1 of the first shell 110 relative to the first shell 110.

[0031] Such a configuration allows the second shell 120, the magnetic assembly 130 and the supported device to rotate synchronously when the user adjusts the posture of the supported device along the circumferential direction D1 of the first shell 110, so that there is no sliding friction between the second shell 120 and the supported device, or the sliding friction between the second shell 120 and the supported device can be reduced, and at the same time, the resistance of the magnetic assembly 130 to the rotation of the supported device is reduced, which is beneficial to improving the smoothness of the rotation of the supported device and reducing the effort of the user.

[0032] In some embodiments, the magnetic component 130 is detachably connected to the second housing 120. In other embodiments, the magnetic component 130 is fixedly connected to the second housing 120, for example, by glue.

[0033] Alternatively, if Figure 1 , Figures 6 to 8As shown, the magnetic attraction assembly 130 is connected to the first shell 110, so that the supported device and the second shell 120 can rotate together around the first reference axis L1 relative to the first shell 110 and the magnetic attraction assembly 130. Further, the supported device and the second shell 120 can rotate together along the circumferential direction D1 of the first shell 110 relative to the first shell 110 and the magnetic attraction assembly 130.

[0034] In this way, when the user adjusts the posture of the supported device along the circumference D1 of the first shell 110, there may be no sliding friction between the second shell 120 and the supported device, or the sliding friction between the second shell 120 and the supported device can be reduced, which is beneficial to improving the rotation smoothness of the supported device.

[0035] Specifically, sliding friction refers to the friction between the second shell 120 and the supported device when they slide relative to each other, and the friction between the second shell 120 and the supported device when they are relatively fixed is static friction. In some embodiments, the magnetic attraction of the second shell 120 to the supported device is strong, or the friction coefficient between the second shell 120 and the supported device is large. When the user adjusts the posture of the supported device along the circumference D1 of the first shell 110, there is no sliding friction between the second shell 120 and the supported device, that is, the second shell 120 and the supported device rotate completely synchronously. In other embodiments, the magnetic attraction of the second shell 120 to the supported device is weak, or the friction coefficient between the second shell 120 and the supported device is small. When the user adjusts the posture of the supported device along the circumference D1 of the first shell 110, there is sliding friction between the second shell 120 and the supported device, that is, the second shell 120 and the supported device do not rotate completely synchronously.

[0036] In some embodiments, the magnetic component 130 is detachably connected to the first housing 110. In other embodiments, the magnetic component 130 is fixedly connected to the first housing 110, for example, by glue.

[0037] In some embodiments, Figure 6 As shown, during the assembly process, the magnetic attraction component 130 can be pre-fixed by the fixing plate 143, and then the fixing plate 143 and the magnetic attraction component 130 are assembled together on the first shell 110, so that the magnetic attraction component 130 can be easily assembled.

[0038] Optionally, as shown in FIG. Figures 2 to 5 As shown, a bearing 151 is disposed between the second housing 120 and the first housing 110 . The second housing 120 and the first housing 110 rotate relative to each other through the bearing 151 .

[0039] The bearing 151 is provided to improve the smoothness of the relative rotation between the second housing 120 and the first housing 110 , and the bearing 151 can be easily assembled.

[0040] Optionally, the inner ring of the bearing 151 is sleeved on the first housing 110, and the second housing 120 is sleeved on the outer ring of the bearing 151. Such a configuration is conducive to reducing the size of the first housing 110 and increasing the size of the second housing 120. On the one hand, due to the shielding of the second housing 120, the first housing 110 is not easily visible from the side where the support device 1 adsorbs the supported device, which is conducive to improving the appearance. On the other hand, it is conducive to increasing the area of ​​the surface of the first housing 110 where the supported device is placed.

[0041] Alternatively, if Figures 2 to 4 As shown, a bearing 151 is provided between the second housing 120 and the first housing 110. The first housing 110 includes an inner housing 113 and an outer housing 114. The second housing 120 and the inner housing 113 are surrounded to form a receiving space 160. The outer housing 114 is located at the periphery of the inner housing 113, and an installation space 115 is formed between the outer housing 114 and the inner housing 113. The bearing 151 is provided in the installation space 115 and sleeved on the outer periphery of the inner housing 113. The second housing 120 extends into the installation space 115 and abuts against the outer ring of the bearing 151.

[0042] By arranging the bearing 151 in the installation space 115, the outer shell 114 can shield and protect the bearing 151, which is beneficial for the bearing 151 to maintain a stable assembly relationship with the inner shell 113 and the second shell 120, thereby improving the structural stability and appearance.

[0043] Alternatively, if Figures 2 to 4 As shown, the outer periphery of the inner housing 113 has a mounting step 1162 , and the bearing 151 can be mounted on the mounting step 1162 , so as to facilitate the installation of the bearing 151 .

[0044] Optionally, the inner housing 113 and the outer housing 114 may be fixed together by screws.

[0045] Optionally, both the inner shell 113 and the outer shell 114 are provided with reinforcing ribs 1132 to increase strength, which is beneficial for uniform wall thickness and can reduce surface collapse caused by uneven shrinkage during molding.

[0046] Alternatively, if Figures 2 to 4As shown, the second shell 120 includes an upper cover 124 and a middle frame 125. One end of the middle frame 125 has an installation port (not marked), through which the magnetic suction component 130 can be installed, and the upper cover 124 can be used to block the installation port. The supported device can be located on the outside of the upper cover 124. The other end of the middle frame 125 can extend into the installation space 115 and abut against the outer ring of the bearing 151. Such a configuration can facilitate the assembly of the bracket device 1. In some embodiments, the magnetic suction component 130 can be fixed to the upper cover 124.

[0047] Optionally, the upper cover 124 and the middle frame 125 are connected by glue or by snap fastening.

[0048] Alternatively, if Figure 1 , Figures 2 to 4 As shown, the bracket device 1 has a front side 102 and a back side 103 and a peripheral side surface 104 connected between the front side 102 and the back side 103, the front side 102 is used to adsorb the supported device, the supporting mechanism 200 is connected to the first shell 110 at the back side 103, and the seam 105 between the second shell 120 and the first shell 110 on the outer surface of the bracket device 1 is located on the back side 103 or the peripheral side surface 104.

[0049] That is, the second shell 120 can cover the first shell 110 on the front side 102 of the bracket device 1 , so that the joint 105 between the second shell 120 and the first shell 110 is located on the back side 103 or the peripheral side 104 .

[0050] The seam 105 between the second shell 120 and the first shell 110 refers to the seam 105 at the junction of the second shell 120 and the first shell 110. For example, the seam 105 between the second shell 120 and the first shell 110 on the outer surface of the bracket device 1 is the seam 105 between the middle frame 125 and the first shell 110. Further, the seam 105 between the second shell 120 and the first shell 110 on the outer surface of the bracket device 1 is the seam 105 between the middle frame 125 and the outer shell 114.

[0051] In some embodiments, the seam 105 between the second shell 120 and the first shell 110 on the outer surface of the bracket device 1 is located on the peripheral side surface 104. In some embodiments, the middle frame 125 has a shielding portion 1251 located on the peripheral side surface 104, and the second shell 120 can shield the first shell 110 on the peripheral side surface 104 so that the seam 105 between the second shell 120 and the first shell 110 on the outer surface of the bracket device 1 is located on the back surface 103.

[0052] Such an arrangement is helpful to improve the aesthetic appearance of the bracket device 1.

[0053] Alternatively, if Figures 6 to 8As shown, a rolling member 152 is disposed between the second housing 120 and the first housing 110 . The second housing 120 and the first housing 110 rotate relative to each other through the rolling member 152 .

[0054] The provision of the rolling element 152 is conducive to improving the smoothness of the relative rotation between the second housing 120 and the first housing 110, and the rolling element 152 can have the characteristic of being small in size. For example, the rolling element 152 is a ball, a needle, or a cylindrical roller. There can be multiple rolling elements 152, and the multiple rolling elements 152 can be distributed at intervals or continuously along the circumferential direction D1 of the first housing 110.

[0055] In some embodiments, the rolling member 152 is located between the upper cover 124 and the first housing 110. In other embodiments, the rolling member 152 is located between the middle frame 125 and the first housing 110.

[0056] In some embodiments, a groove (not marked) is formed on one of the second shell 120 and the first shell 110 to accommodate the rolling element 152 , and the opening direction of the groove is parallel or perpendicular to the axis direction of rotation of the second shell 120 relative to the first shell 110 .

[0057] In some embodiments, the bearing 151 and the rolling element 152 may not be disposed between the second housing 120 and the first housing 110 .

[0058] Alternatively, if Figure 1 , Figure 2 and Figure 5 As shown, the first housing 110 is provided with a stop surface 116 distributed along the circumference D1 of the first housing 110, and the stop surface 116 is used to stop the second housing 120 to limit the second housing 120 from separating from the first housing 110. The stop surface 116 is distributed along the circumference D1 of the first housing 110 at intervals or continuously.

[0059] Specifically, the stop surface 116 is used to limit the second housing 120 from being separated from the first housing 110 along a direction extending relative to the rotation axis of the first housing 110 .

[0060] In some embodiments, Figure 2 As shown, the stop surface 116 is located in the installation space 115 and on the step surface of the above-mentioned installation step 1162.

[0061] In other embodiments, Figure 5 As shown, a stop plate 1161 is fixed on the inner shell 113 , and the stop surface 116 is located at the edge of one side of the stop plate 1161 .

[0062] In other embodiments, Figure 6As shown, the fixing plate 143 is fixed on the first shell 110 , and the stop surface 116 is located at an edge of the fixing plate 143 which is away from the magnetic attraction assembly 130 .

[0063] Furthermore, the stopping surface 116 is used to stop the middle frame 125 to limit the second shell 120 from being separated from the first shell 110 .

[0064] In this way, the stop surface 116 allows the second housing 120 and the first housing 110 to rotate relative to each other and restricts the second housing 120 and the first housing 110 from being separated from each other.

[0065] Alternatively, if Figures 1 to 3 As shown, one of the second shell 120 and the first shell 110 is provided with an elastic protrusion 106, and the other of the second shell 120 and the first shell 110 is provided with a plurality of snap grooves 107 distributed along the circumference D1 of the first shell 110, and the plurality of snap grooves 107 are used for snapping with the elastic protrusion 106.

[0066] Specifically, the second housing 120 is provided with an elastic protrusion 106, and the first housing 110 is provided with a plurality of snap grooves 107 distributed along the circumferential direction D1 of the first housing 110, and the plurality of snap grooves 107 are used to snap with the elastic protrusion 106. Or the first housing 110 is provided with an elastic protrusion 106, and the second housing 120 is provided with a plurality of snap grooves 107 distributed along the circumferential direction of the second housing 120, and the plurality of snap grooves 107 are used to snap with the elastic protrusion 106.

[0067] For example, in some embodiments, the elastic protrusion 106 is disposed on the inner shell 113, the middle frame 125 is an annular structure, and a plurality of snap grooves 107 are disposed on the inner ring of the middle frame 125. For another example, the elastic protrusion 106 is disposed on the outer ring of the middle frame 125, and a plurality of snap grooves 107 are disposed on the inner surface of the outer shell 114.

[0068] By setting the elastic protrusion 106 to engage with the snap groove 107, the relative rotation of the second housing 120 and the first housing 110 can be limited to a certain extent, which is conducive to maintaining the stability of the posture of the supported device. When the second housing 120 is subjected to force, the second housing 120 and the first housing 110 rotate relative to each other, and the elastic protrusion 106 can be disengaged from the original snap groove 107 to allow the second housing 120 and the first housing 110 to rotate relative to each other. As the second housing 120 and the first housing 110 continue to rotate relative to each other, the elastic protrusion 106 will continue to be engaged in new snap grooves 107 until the second housing 120 and the first housing 110 stop rotating relative to each other.

[0069] Optionally, the elastic protrusion 106 is a spring pin. Alternatively, the elastic protrusion 106 is a component made of elastic plastic, silicone or rubber, connected to the second housing 120 or the first housing 110 through an elastic arm, and deformed by the elastic arm to disengage from or snap into the snap groove 107. In some embodiments, the elastic protrusion 106 is formed by bending a metal sheet into a corrugated shape, and a deformation space is formed after the metal sheet is bent, thereby allowing the metal sheet to deform to disengage from or snap into the snap groove 107.

[0070] In some embodiments, the second housing 120 and the first housing 110 may be provided with a limiting structure to limit the relative rotation angle of the second housing 120 and the first housing 110 within a certain range. In other embodiments, the second housing 120 and the first housing 110 may not be provided with a limiting structure to allow the second housing 120 and the first housing 110 to rotate relative to each other for one or more circles.

[0071] In some embodiments, the second housing 120 and the first housing 110 may be rotatably connected via threads.

[0072] Optionally, the outer circumferential surface of the first shell 110 is approximately a part of a sphere, the support mechanism 200 is connected to the center position of the outer circumferential surface of the first shell 110, and the center position of the outer circumferential surface of the first shell 110 is protruded outward, thereby reducing the probability of mutual interference between the support mechanism 200 and the first shell 110 during relative rotation.

[0073] Alternatively, if Figures 1 to 3 As shown, the support mechanism 200 includes a support rod 220 and a base 210 connected to each other, and the support rod 220 is rotatably connected to the first shell 110 .

[0074] Optionally, the base 210 is rotatably connected to the support rod 220. The support rod 220 rotates relative to the base 210 to drive the first housing 110 to move closer to or away from the base 210. With this arrangement, the support mechanism 200 can be folded to facilitate storage of the bracket device 1.

[0075] Alternatively, if Figure 1 As shown, the support rod 220 can rotate relative to the base 210 around the third reference axis L3. The extension direction of the third reference axis L3 is perpendicular to the height direction of the support mechanism 200. In this way, the support rod 220 can adjust the pitch angle of the supported device by rotating relative to the base 210. The third reference axis L3 is the rotation axis of the support rod 220 relative to the base 210. In some embodiments, the third reference axis L3 is parallel to the second reference axis L2. In other embodiments, the extension direction of the third reference axis L3 is perpendicular to the extension direction of the second reference axis L2.

[0076] Alternatively, if Figure 1As shown, the base 210 includes a first base body and a second base body that are rotatably connected, and the first base body is rotatable relative to the second base body around a fourth reference axis L4. The fourth reference axis L4 is the rotation axis of the first base body relative to the second base body. Further, the fourth reference axis L4 intersects with the second reference axis L2. For example, the third reference axis L3 extends along the height direction of the support mechanism 200, and the second reference axis L2 is perpendicular to the height direction of the support mechanism 200. Such an arrangement is conducive to increasing the freedom of movement of the supported device. In some embodiments, the first base body and the second base body can rotate relative to each other for at least one circle, and can achieve a 360° rotation of the supported device around the fourth reference axis L4.

[0077] Optionally, the support rod 220 is configured to be retractable or foldable, and the support rod 220 can adjust its height through a retractable movement or a folding movement for easy storage. For example, the support rod 220 includes a first sub-rod body and a second sub-rod body that are rotatably connected, and the first sub-rod body and the second sub-rod body can achieve folding or extension of the support rod 220 through relative rotation.

[0078] In some embodiments, the support rod 220 is an independent rod, which can be a straight rod, a bent rod, etc. In some embodiments, the support rod 220 can include two rods or multiple rods arranged side by side. In some embodiments, the cross-sectional shape of the support rod 220 is circular or rectangular.

[0079] Alternatively, if Figures 1 to 3 As shown, a ball head 201 is provided on the support mechanism 200 , a connecting groove 117 is opened on the first shell 110 and an elastic member 118 is provided in the connecting groove 117 , and the ball head 201 can rotatably extend into the connecting groove 117 and elastically abut against the elastic member 118 .

[0080] When the support mechanism 200 and the first shell 110 rotate relative to each other, the ball head 201 can rotate in the connection groove 117 and slide relative to the elastic member 118. The ball head 201 can be inserted into the connection groove 117, thereby limiting the support mechanism 200 from being separated from the first shell 110. The first shell 110 can cover the ball head 201 to improve the appearance. By elastically contacting the ball head 201 with the elastic member 118, the rotation resistance of the ball head 201 in the connection groove 117 can be increased, preventing the ball head 201 from deviating from the working position due to looseness.

[0081] Optionally, the elastic member 118 forms the bottom surface of the connecting groove 117. Further, the elastic member 118 is a plastic member, a silicone member or a rubber member.

[0082] Alternatively, if Figures 1 to 3As shown, the elastic member 118 has a first semi-cylindrical surface 119, and the ball head 201 has a second semi-cylindrical surface 202 abutting against the first semi-cylindrical surface 119, and the generatrix extension direction of the first semi-cylindrical surface 119 and the generatrix extension direction of the second semi-cylindrical surface 202 are both parallel to the second reference axis L2. Among them, the generatrix extension direction of the first semi-cylindrical surface 119 and the second semi-cylindrical surface 202 are both parallel to the second reference axis L2, which also includes: the generatrix extension direction of the first semi-cylindrical surface 119 and the second semi-cylindrical surface 202 can also be approximately parallel to the second reference axis L2. Further, the second reference axis L2 is the central axis of the first semi-cylindrical surface 119. The central axes of the first semi-cylindrical surface 119 and the second semi-cylindrical surface 202 are collinear.

[0083] Such a configuration allows the support mechanism 200 and the first shell 110 to rotate relative to each other around the second reference axis L2 to facilitate adjustment of the posture of the supported device. It can also limit the relative movement of the support mechanism 200 and the first shell 110 along the second reference axis L2, which is beneficial to maintaining the supporting stability of the support mechanism 200 for the supported device.

[0084] Optionally, the curvature of the second semi-cylindrical surface 202 matches that of the first semi-cylindrical surface 119 , which can improve the fit between the second semi-cylindrical surface 202 and the first semi-cylindrical surface 119 , and is conducive to stable contact between the elastic member 118 and the ball head 201 .

[0085] Alternatively, if Figure 1 and Fig. 9 As shown, one of the support mechanism 200 and the first housing 110 is provided with a connecting shaft section 204, and the other of the support mechanism 200 and the first housing 110 is provided with a connecting hole 203, and the connecting shaft section 204 is inserted into the connecting hole 203 and is interference-fitted with the connecting hole 203. Further, the connecting shaft section 204 and the connecting hole 203 are made of metal to improve strength and service life.

[0086] Such a configuration allows the support mechanism 200 and the first shell 110 to rotate relative to each other around the second reference axis L2 when subjected to force, so as to adjust the posture of the supported device. It can also increase the friction force through the interference fit between the connecting shaft segment 204 and the connecting hole 203, thereby limiting the relative movement of the support mechanism 200 and the first shell 110 to a certain extent, which is beneficial to the supporting stability of the support mechanism 200 for the supported device.

[0087] In some embodiments, Fig. 9As shown, the first housing 110 is provided with a connecting shaft section 204, and the supporting mechanism 200 is provided with a connecting hole 203. The connecting shaft section 204 may include a column 2041 and a connecting piece 2042, one end of the connecting piece 2042 is arranged around the column 2041 and is located in the connecting hole 203 with the column 2041, a connecting groove 117 is provided on the first housing 110, a sidewall of the connecting hole 203 is provided with an avoidance opening 2031 and is connected with the connecting groove 117 through the avoidance opening 2031, and the other end of the connecting piece 2042 can movably extend through the avoidance opening 2031 into the connecting groove 117 and be fixed in the connecting groove 117. Such a configuration allows the connecting shaft section 204 to rotate in the connecting hole 203, which can facilitate the assembly connection between the supporting mechanism 200 and the first housing 110.

[0088] To sum up, this embodiment can achieve that when the user adjusts the posture of the supported device along the circumferential direction D1 of the first shell 110, the second shell 120 and the supported device can rotate synchronously, so that there is no sliding friction between the second shell 120 and the supported device, which is beneficial to improving the rotation smoothness of the supported device and enhancing the user's feel. For example, the supported device can be a mobile phone or a tablet computer. By rotating the supported device relative to the first shell 110, the posture of the mobile phone or tablet computer display can be adjusted, so that the mobile phone or tablet computer can switch between horizontal and vertical screens, and the mobile phone or tablet computer can be straightened from a skewed state.
