The bracket assembly further includes a second clamping portion. The second clamping portion includes a third clamping arm. The third clamping arm has a third surface. Along the first direction, one side of the first surface is adapted to clamp the electronic device, and the second surface and the third surface are adapted to jointly clamp the other side of the electronic device.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] The bracket assembly of the present utility model includes a first clamping portion. The first clamping portion includes a first clamping arm and a second clamping arm that can rotate relative to each other. Corresponding to different relative rotation positions of the two, the first clamping portion has a first position and a second position. When the first clamping portion is in the first position, since the first projection can cover the second projection, the clamping forces exerted by the first clamping arm and the second clamping arm on both sides of the electronic device are relatively concentrated. Therefore, the bracket assembly at this time can be adapted to clamp a certain side edge of the electronic device concentrically. When the first clamping portion is in the second position, since the first projection and the second projection are spaced apart, the clamping forces exerted by the first clamping arm and the second clamping arm on both sides of the electronic device are relatively dispersed. Therefore, the bracket assembly at this time can be adapted to clamp different parts of the electronic device in a staggered and dispersed manner, and the bracket assembly at this time is suitable for stably clamping larger-sized electronic devices. Compared with the bracket with a single clamping angle in the related art, the bracket assembly of the present utility model can adjust the clamping angle by the relative rotation of the first clamping arm and the second clamping arm, so that the bracket assembly can be adapted to more specifications of electronic devices, and the clamping methods are diverse. Therefore, the bracket assembly of the present utility model can facilitate the adjustment of the clamping angle, and thus has a better adaptability to electronic devices.

[0042] The realization, functional features and advantages of the present utility model will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0043] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0044] It should be noted that if there are directional indications (such as up, down, left, right, front, back,...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0045] In addition, if the descriptions such as "first" and "second" are involved in the embodiments of the present utility model, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or", "or / and", or "and / or" appear throughout the text, their meanings include three parallel scenarios. Taking "A and / or B" as an example, it includes scenario A, or scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0046] In the related art, the brackets for electronic devices often can only be clamped at a specific angle, with a single usage method. For electronic devices of different sizes and specifications, the bracket cannot adjust the clamping part to adapt to different clamping requirements. More specifically, with the emergence of cars with screens, there are brackets suitable for clamping car screens, but the screen brackets in the related art have a single structure and can only be clamped on the car screen at a specific angle. Since the heights of screens of different sizes and specifications protruding from the car console are different, the screen bracket will show a non-matching phenomenon.

[0047] In view of this, referring to Figures 1-13 , in the embodiments of the present utility model, a bracket assembly 100 is provided, including a first clamping part 110. Referring to Figures 1-6 , the first clamping part 110 includes a first clamping arm 111 and a second clamping arm 112. The first clamping arm 111 has a first surface 1111, and the second clamping arm 112 has a second surface 1121. The first surface 1111 and the second surface 1121 are arranged opposite to each other along the first direction X and are adapted to jointly clamp an electronic device. It can be understood that the first surface 1111 and the second surface 1121 are respectively adapted to abut against the opposite sides of the electronic device along the first direction X to achieve the clamping effect. The electronic device includes, but is not limited to: mobile phones, tablet computers, and car screens. According to requirements, the shapes and sizes of the first surface 1111 and the second surface 1121 may be the same or different; in addition, any suitable method can be used to apply a clamping force to the electronic device. For example, a threaded locking or spring-driven method can be used to apply a force to the first clamping arm 111 and / or the second clamping arm 112 to clamp the electronic device. To achieve a better clamping effect, the first surface 1111 and / or the second surface 1121 can be arranged on components with damping, such as rubber pads, sponge pads, etc.

[0048] Based on the first clamping part 110 defined above, referring toFigures 1-6 , the first clamping part 110 has a first position and a second position. The first clamping arm 111 and the second clamping arm 112 are configured to be relatively rotatable so that the first clamping part 110 can switch between the first position and the second position. Among them, the orthographic projection of the first surface 1111 on the projection plane perpendicular to the first direction X is the first projection, and the orthographic projection of the geometric center of the second surface 1121 on the projection plane is the second projection. When the first clamping part 110 is in the first position, the first projection covers the second projection. When the first clamping part 110 is in the second position, the first projection and the second projection are spaced apart. It can be understood that the first position and the second position respectively correspond to different relative rotational positions of the first clamping arm 111 and the second clamping arm 112. When the first clamping part 110 is in the first position, since the first projection can cover the second projection, the clamping forces applied by the first clamping arm 111 and the second clamping arm 112 on both sides of the electronic device are relatively concentrated. Therefore, the bracket assembly 100 at this time can be adapted to clamp a certain side edge of the electronic device concentrically; when the first clamping part 110 is in the second position, since the first projection and the second projection are spaced apart (that is, the second projection is outside the first projection), the clamping forces applied by the first clamping arm 111 and the second clamping arm 112 on both sides of the electronic device are relatively dispersed. At this time, when observing along the first direction X, the first surface 1111 and the second surface 1121 can be spaced apart or mostly spaced apart (that is, on the premise that the first projection and the second projection are spaced apart, only a small part of the first surface 1111 and the second surface 1121 overlap). Therefore, the bracket assembly 100 at this time can be adapted to clamp different parts of the electronic device in a staggered and dispersed manner. More specifically, at this time, the first surface 1111 can abut against the back part of the electronic device (to play a more stable abutting role, at this time the first surface 1111 can abut against the area near the center of the back of the electronic device), and the second surface 1121 can abut against the side part of the front of the electronic device. It should be noted that the side edge of the electronic device described in the present invention is defined as: when observing along the first direction, the edge part close to the outer contour of the electronic device.

[0049] It should be noted that the first position and the second position described above are two of the positions during the relative rotation of the first clamping arm 111 and the second clamping arm 112. The covering relationship and the spacing relationship between the first projection and the second projection may not be limited to appearing only at the first position and the second position. Specifically, in some embodiments, the first projection can cover the second projection at multiple relative rotation positions during the relative rotation of the first clamping arm 111 and the second clamping arm 112, and the above-mentioned multiple relative rotation positions include the first position; similarly, the first projection and the second projection are spaced apart at multiple relative rotation positions during the relative rotation of the first clamping arm 111 and the second clamping arm 112, and the above-mentioned multiple relative rotation positions include the second position. In other words, it can also be understood that there are multiple first positions, and the relative rotation positions that satisfy the first projection covering the second projection are the first positions, and there are multiple second positions, and the relative rotation positions that satisfy the first projection and the second projection being spaced apart are the second positions.

[0050] From the combination of the above embodiments, it can be seen that the bracket assembly 100 of the present invention includes a first clamping portion 110. The first clamping portion 110 includes a first clamping arm 111 and a second clamping arm 112 that can rotate relative to each other, and corresponding to different relative rotation positions of the two, the first clamping portion 110 has a first position and a second position. When the first clamping portion 110 is in the first position, since the first projection can cover the second projection, the clamping forces applied by the first clamping arm 111 and the second clamping arm 112 on both sides of the electronic device are relatively concentrated, so that the bracket assembly 100 at this time can be adapted to clamp a certain side edge of the electronic device centrally; when the first clamping portion 110 is in the second position, since the first projection and the second projection are spaced apart, the clamping forces applied by the first clamping arm 111 and the second clamping arm 112 on both sides of the electronic device are relatively dispersed, so that the bracket assembly 100 at this time can be adapted to clamp different parts of the electronic device in a staggered and dispersed manner, and the bracket assembly 100 at this time is suitable for stably clamping an electronic device with a larger size. Compared with the bracket with a single clamping angle in the related art, the bracket assembly 100 of the present invention can adjust the clamping angle by the relative rotation of the first clamping arm 111 and the second clamping arm 112, so that the bracket assembly 100 can be adapted to more specifications of electronic devices, and the clamping methods are diverse. Therefore, the bracket assembly 100 of the present invention can facilitate the adjustment of the clamping angle, and thus has a better adaptability to electronic devices.

[0051] For the specific rotation form of the first clamping arm 111 and the second clamping arm 112. Refer to Figure 1 and Figure 4, in some embodiments, the included angle θ1 between the first clamping arm 111 and the second clamping arm 112 satisfies: 0° ≤ θ1 ≤ 90°. Exemplarily, θ1 can take a value of one of 0°, 30°, 60°, 90°. It should be noted that the following defines θ1 as follows: The first clamping arm 111 and the second clamping arm 112 are configured to rotate relative to each other about the rotation axis. Thus, when observed along the first direction X, the first surface 1111 has a first central axis pointing along the rotation axis towards the geometric center of the first surface 1111, and the second surface 1121 has a second central axis pointing along the rotation axis towards the geometric center of the second surface 1121. θ1 is defined as the included angle between the first central axis and the second central axis when observed along the first direction X. Thus, in some embodiments, when the first clamping portion 110 is in the first position, θ1 can be 0°, that is, at this time, the first clamping arm 111 and the second clamping arm 112 can be aligned, so that the clamping forces applied by both are more concentrated (or coincide in the opposite direction). In addition, the above setting limits θ1 within 90°, which can prevent the first clamping arm 111 and the second clamping arm 112 from generating too large an included angle, thereby avoiding the phenomenon of unstable clamping force caused by too far a distance between the clamping forces or the phenomenon of generating too large a moment. According to requirements, the switching form of the included angle θ1 between the first clamping arm 111 and the second clamping arm 112 can be a polar switching (only adjustable to a set angle gear), or a non-polar switching (can be adjusted to any angle within the angle range).

[0052] For the specific rotation structure between the first clamping arm 111 and the second clamping arm 112, refer to Figure 7 , in some embodiments, the bracket assembly 100 further includes a bolt assembly 130. The first clamping arm 111 has a first hole 1112, and the second clamping arm 112 has a second hole 1122. The bolt assembly 130 is inserted through the first hole 1112 and the second hole 1122 along the first direction X, so that the first clamping arm 111 and the second clamping arm 112 can rotate relative to each other about the bolt assembly 130, and the bolt assembly 130 is configured to be able to lock the relative positions of the first clamping arm 111 and the second clamping arm 112. Among them, the bolt assembly 130 can specifically include a screw 113, a nut, and a knob. One end of the screw 113 passing through the first hole 1112 and the second hole 1122 can cooperate with the nut, and the other end can be fixedly connected to the knob. Thus, the user can rotate the knob to make the knob and the nut respectively abut against both sides of the bracket assembly 100 along the first direction X, thereby achieving the effect of locking the relative positions of the first clamping arm 111 and the second clamping arm 112. When the user loosens the bolt assembly 130, the included angle between the first clamping arm 111 and the second clamping arm 112 can be adjusted according to requirements.

[0053] For the specific clamping form of the first clamping arm 111 and the second clamping arm 112, refer to Figures 7-8, in some embodiments, the first clamping arm 111 has a threaded hole 1113 extending along the first direction X. The first clamping portion 110 further includes a screw 113, and the screw 113 is inserted through the threaded hole 1113 so that the screw 113 can drive the first clamping arm 111 to move relative to the second clamping arm 112 along the first direction X. It can be understood that the user can rotate the screw 113 (specifically, rotate the knob connected to the end of the screw 113) to make the first clamping arm 111 perform a screwing-in motion, and make the first clamping arm 111 move relatively closer to the second clamping arm 112 along the first direction X, that is, make the first surface 1111 approach the second surface 1121 to play a clamping role. Further, in some embodiments, the second clamping arm 112 has a limiting block 1123. Along the first direction X, the limiting block 1123 is located on the side of the second surface 1121 close to the first surface 1111 and is configured to be able to abut against the first clamping arm 111. It can be understood that due to the above abutting effect, the first clamping arm 111 can be prevented from disengaging from the screw 113 during the process of approaching the second clamping arm 112.

[0054] In addition, in some other embodiments, the above-mentioned threaded hole 1113 can also be provided on the second clamping arm 112, and the screw 113 is also inserted through the threaded hole 1113, so that the screw 113 can drive the second clamping arm 112 to move relative to the first clamping arm 111 along the first direction X. Based on this, the first clamping arm 111 can have a limiting block 1123. Along the first direction X, the limiting block 1123 can be located on the side of the first surface 1111 close to the second surface 1121 and is configured to be able to abut against the second clamping arm 112.

[0055] In addition to the above clamping forms, in some other embodiments, the first clamping portion 110 further includes an elastic member. The first clamping arm 111 can be connected to the elastic member, so that the elastic member can be configured to apply an elastic force along the first direction X to the first clamping arm 111 to achieve a clamping effect.

[0056] To achieve a better clamping effect, refer to Figure 1 or Figure 2, in some embodiments, the first clamping arm 111 includes a first adsorption pad 1114. The first adsorption pad 1114 has a first surface 1111, and a third hole 11111 is provided on the first surface 1111. The first adsorption pad 1114 is configured to be deformed by extrusion when clamping an electronic device, so that the third hole 11111 adsorbs the electronic device. It can be understood that the first adsorption pad 1114 can be made of an elastic material, for example, any one of rubber, silica gel, and sponge. Thus, when the first adsorption pad 1114 abuts and clamps the electronic device, the air in the third hole 11111 is extruded to the outside, and the electronic device blocks the third opening, thereby forming a pressure difference between the third opening and the outside, and further enabling the third hole 11111 to adsorb the electronic device. In addition, a similar setting can be made for the second clamping arm 112, see Figure 1 or Figure 2 , in some embodiments, the second clamping arm 112 includes a second adsorption pad 1124. The second adsorption pad 1124 has a second surface 1121, and a fourth hole 11211 is provided on the second surface 1121. The second adsorption pad 1124 is configured to be deformed by extrusion when clamping an electronic device, so that the fourth hole 11211 adsorbs the electronic device. The relevant settings of the second adsorption pad 1124 can refer to the relevant settings of the above-mentioned first adsorption pad 1114, which will not be elaborated here.

[0057] To achieve more diverse clamping methods, based on the relative rotation of the first clamping arm 111 and the second clamping arm 112 around the rotation axis, and the definition that the rotation axis is parallel to the first direction X, see Figure 2 and Figure 5 , in some embodiments, the bracket assembly 100 further includes a second clamping portion 120. The second clamping portion 120 includes a third clamping arm 121. The third clamping arm 121 has a third surface 1211. Along the first direction X, one side of the first surface 1111 is adapted to clamp the electronic device, and the second surface 1121 and the third surface 1211 are adapted to jointly clamp the other side of the electronic device. The third clamping arm 121 and the second clamping arm 112 are configured to be able to rotate relative to each other around the rotation axis. It can be understood that the third clamping arm 121 and the second clamping arm 112 jointly clamp one side of the electronic device, and the rotational setting of the third clamping arm 121 enables the second surface 1121 and the third surface 1211 to clamp different parts of the electronic device according to the change of the angle respectively, so that the clamping action area (corresponding to the area that the clamping force can cover along the first direction X) can be expanded and the clamping action is more stable. In particular, it can further be adapted to clamp larger-sized electronic devices.

[0058] According to the definition of the above-mentioned second clamping portion 120, on the one hand, see Figure 9, the second clamping part 120 can increase the clamping area only through the cooperation between the third surface 1211 and the second surface 1121 of the second clamping arm 112, that is, the second clamping part 120 can only include one clamping arm structure (the third clamping arm 121). On the other hand, referring to Figure 2 , Figure 3 and Figure 5 , the structural form of the second clamping part 120 can also be similar to that of the first clamping part 110, that is, it includes two rotatable clamping arm structures. Specifically, in some embodiments, the second clamping part 120 further includes a fourth clamping arm 122. Thus, the third clamping arm 121 has a third surface 1211, the fourth clamping arm 122 has a fourth surface 1221, the third surface 1211 and the fourth surface 1221 are arranged opposite to each other along the first direction X and are adapted to jointly clamp the electronic device. The second clamping part 120 has a third position and a fourth position. The third clamping arm 121 and the fourth clamping arm 122 are configured to be able to rotate relative to each other around the rotation axis so that the second clamping part 120 can be switched between the third position and the fourth position. Based on the above definition of the second clamping part 120, the orthographic projection of the third surface 1211 on the projection plane is the third projection, and the orthographic projection of the geometric center of the fourth surface 1221 on the projection plane is the fourth projection. When the second clamping part 120 is in the third position, the third projection covers the fourth projection. When the second clamping part 120 is in the fourth position, the third projection and the fourth projection are spaced apart.

[0059] Similar to the first position and the second position described above, it should be noted that the third position and the fourth position are two of the positions during the relative rotation of the third clamping arm 121 and the fourth clamping arm 122. The covering relationship and the spacing relationship between the third projection and the fourth projection may not be limited to appearing in the third position and the fourth position. Specifically, in some embodiments, multiple relative rotation positions during the relative rotation of the third clamping arm 121 and the fourth clamping arm 122 can all satisfy that the third projection covers the fourth projection, and the above multiple relative rotation positions include the third position; similarly, multiple relative rotation positions during the relative rotation of the third clamping arm 121 and the fourth clamping arm 122 can all satisfy that the third projection and the fourth projection are spaced apart, and the above multiple relative rotation positions include the fourth position. In other words, it can also be understood that there are multiple third positions, and the relative rotation positions that satisfy the third projection covering the fourth projection are the third positions, and there are multiple fourth positions, and the relative rotation positions that satisfy the third projection and the fourth projection being spaced apart are the fourth positions.

[0060] For the second clamping part 120 defined above, referring to Figure 2 and Figure 5, it can be understood that when the first clamping part 110 and the second clamping part 120 are viewed separately and independently, their respective structures, configurations and functions are similar (or the same); and when the first clamping part 110 and the second clamping part 120 cooperate with each other, that is: on the basis that the first clamping arm 111 and the second clamping arm 112, as well as the third clamping arm 121 and the fourth clamping arm 122 are configured to be relatively rotatable, the whole of the first clamping part 110 and the whole of the second clamping part 120 are further configured to be relatively rotatable. The above-mentioned cooperation enables the user to adjust the angle of any clamping arm (the first clamping arm 111, the second clamping arm 112, etc.) separately according to needs, and can also adjust the angle between the whole of the first clamping part 110 and the whole of the second clamping part 120, so that the bracket assembly 100 has more diverse clamping methods. More specifically, referring to Figure 3 or Figure 13 , in the first clamping method, the first clamping part 110 is located at the first position, and the second clamping part 120 is located at the third position. At this time, the two can jointly clamp the side of the electronic device. Referring to Figure 10 , in the second clamping method, the first clamping part 110 is located at the second position, and the second clamping part 120 is located at the third position. At this time, when viewed along the first direction X, each clamping arm can jointly form a "T" - shaped structure or a "Y" - shaped structure. The above setting can not only stably clamp the side part of the electronic device through the first clamping part 110, but also increase the clamping area through the second clamping part 120, making the clamping effect more stable. Referring to Figure 11 or Figure 12 , in the third clamping method, the first clamping part 110 is located at the second position, and the second clamping arm 112 is located at the fourth position. At this time, when viewed along the first direction X, each clamping arm can jointly form a "big" - shaped structure or a "cross" - shaped structure. The above setting can make the clamping area of the bracket assembly 100 larger, so that the clamping effect is more stable and more suitable for stably clamping larger - sized electronic devices.

[0061] Based on the second clamping part 120 of the above - mentioned embodiments, referring to Figure 13, in some embodiments, the included angle θ2 between the second clamping portion 120 and the second clamping arm 112 satisfies: 0° ≤ θ2 ≤ 90°. Exemplarily, θ2 can take a value of one of 0°, 30°, 60°, 90°. The following defines θ2 as follows: When observed along the first direction X, the third surface 1211 has a third central axis pointing from the rotation axis to the geometric center of the third surface 1211, and the fourth surface 1221 has a fourth central axis pointing from the rotation axis to the geometric center of the fourth surface 1221. θ2 is defined as the included angle between the third central axis and the fourth central axis when observed along the first direction X. It can be understood that the definition and setting of θ2 are similar to those of θ1 in the above embodiments. Similarly, by restricting θ2 to within 90°, it is possible to prevent an excessive included angle between the third clamping arm 121 and the fourth clamping arm 122, thereby avoiding the phenomenon of unstable clamping force caused by too far a distance of the clamping force or the phenomenon of generating too large a torque. In addition, referring to the figure, in combination with the setting of 0° ≤ θ1 ≤ 90° and the setting of 0° ≤ θ2 ≤ 90°, it can be seen that when observed along the first direction X, the first clamping portion 110 and the second clamping portion 120 are respectively responsible for clamping both lateral sides of the electronic device. Also, since the clamping arms of the two clamping portions can rotate relative to each other within the range of 0° to 90°, the bracket assembly 100 can cover a larger clamping angle, so that the user can adjust the clamped portion of the electronic device according to needs, making the clamping effect more stable.

[0062] In addition, based on the second clamping portion 120 defined above, referring to the figure, in some embodiments, when the first clamping portion 110 is located at the first position and the second clamping portion 120 is located at the third position, the included angle θ3 between the first clamping portion 110 and the second clamping portion 120 satisfies: 90° ≤ θ3 ≤ 180°. Exemplarily, θ3 can take a value of one of 90°, 100°, 120°, 140°, 160°, 180°. The following defines θ3 as follows: When observing along the first direction X, the combined figure of the first projection and the second projection has a first outer contour, the combined figure of the third projection and the fourth projection has a second outer contour, the first clamping portion 110 has a fifth central axis pointing along the rotation axis to the geometric center of the first outer contour, the second clamping portion 120 has a sixth central axis pointing along the rotation axis to the geometric center of the second outer contour, and θ3 is defined as the included angle between the fifth central axis and the sixth central axis when observing along the first direction X. It can be understood that the above situation means that the first clamping arm 111 and the second clamping arm 112, as well as the third clamping arm 121 and the fourth clamping arm 122, all apply the clamping force concentratedly, so that both the first clamping portion 110 and the second clamping portion 120 can clamp the side of the electronic device. Also, since the whole of the first clamping portion 110 and the whole of the second clamping portion 120 can rotate relative to each other within the range of 0° to 90°, the first clamping portion 110 and the second clamping portion 120 can respectively clamp two adjacent sides of the electronic device. For example, when the electronic device is square or rectangular when observed along the first direction X, the included angle between the two clamping portions can be adjusted to 90°, so as to respectively clamp two adjacent sides of the electronic device at 90°.

[0063] For the rotational setting of the second clamping portion 120, it can be similar to that of the first clamping portion 110, that is, the third clamping arm 121 can have a third hole 11111, the fourth clamping arm 122 has a fourth hole 11211, and the bolt assembly 130 passes through the first hole 1112, the second hole 1122, the third hole 11111, and the fourth hole 11211 at the same time, so that each clamping arm can rotate independently.

[0064] To make it easier for the first clamping portion 110 and the second clamping portion 120 to rotate relative to each other, in some embodiments, the second clamping arm 112 includes a plurality of grooves distributed around the rotation axis, and the fourth clamping arm 122 includes a protrusion extending towards the rotation axis. During the relative rotation of the second clamping arm 112 and the fourth clamping arm 122, the protrusion cooperates with each groove in sequence to achieve the effect of stabilizing the angle between the two and making angle positioning more convenient. Further, the setting position of the protrusion (or groove) can be determined according to the rotation angle requirement. For example, in some embodiments, the grooves are continuously distributed around the rotation axis, and the fourth clamping arm 122 includes four protrusions distributed around the rotation axis with an included angle of 90°. Additionally, to limit the angle between the clamping arms, in some other embodiments, along the circumferential direction of the rotation axis, abutting blocks can be provided on the side where the clamping arms are close to each other. When the angle between the clamping arms is too small or too large, one of the clamping arms can abut against the abutting block, thereby limiting the angle between the clamping arms. More specifically, in some embodiments, an abutting block can be provided on the side of the first clamping arm 111 close to the third clamping arm 121 along the circumferential direction of the rotation axis. Thus, when the first clamping arm 111 and the third clamping arm 121 approach each other to the limit position, the abutting block can fit against the side of the third clamping arm 121 close to the first clamping arm 111 along the circumferential direction of the rotation axis to form a limiting effect.

[0065] To facilitate the installation of the bracket assembly 100, referring to the figure, in some embodiments, the bracket assembly 100 may further include a spherical joint 140. Thus, the spherical joint 140 can be embedded and installed at the installation site required by the user, such as the car center console, etc., and the installed bracket assembly 100 can achieve angle adjustment by relying on the relative rotation of the spherical joint 140.

Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the application concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
