[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] This utility model embodiment provides a bracket, such as Figures 1 to 5 As shown, the bracket includes a support assembly 1, a base 2, a rotating component 3, a first gear tooth 4, a mounting platform 5, and an elastic positioning assembly 6. The support assembly 1 is connected to the rotating component 3, and the first gear tooth 4 is mounted on the side of the rotating component 3 away from the support assembly 1. The rotating component 3 has a first fitting opening 31, and the first gear tooth 4 has a second fitting opening 41. The rotating component 3 and the first gear tooth 4 are rotatably fitted onto the mounting platform 5 through the first fitting opening 31 and the second fitting opening 41, respectively. The mounting platform 5 is mounted on the base 2.

[0030] The second set of fittings 41 has a first gear tooth 42 around its side wall. The mounting platform 5 has a first mounting groove 51 on the side corresponding to the first gear tooth 42. The elastic positioning component 6 is installed in the first mounting groove 51. The elastic positioning component 6 includes an elastic element (not shown) and a positioning block 61. The elastic element abuts against the groove wall of the first mounting groove 51 and the positioning block 61 respectively to push the positioning block 61 part out of the first mounting groove 51 and into the first gear tooth 42.

[0031] The bracket of this utility model has a second fitting opening 41 on the first gear member 4. The side wall of the second fitting opening 41 is provided with first gear teeth 42. The positioning block 61 is driven by the elastic member to engage with the first gear teeth 42, positioning the rotating member 3. Through the cooperation between the first gear teeth 42 and the positioning block 61, the positioning effect of the rotating member 3 can be improved, the rotation angle can be firmly positioned, and unexpected rotation can be avoided, resulting in a better user experience.

[0032] Specifically, the support component 1 is used to support electronic devices such as mobile phones. When the user rotates the rotating component 3, the rotating component 3 drives the first gear 4 to rotate, and the first gear 42 moves relative to the positioning block 61. The positioning block 61 slides on the first gear 42. After the rotating component 3 stops rotating, the positioning block 61 is engaged into the current first gear 42 under the action of the elastic element. The elastic element can be a spring.

[0033] Furthermore, such as Figures 2 to 5 As shown, a central gear 7 and two transmission gears 8 are rotatably mounted on the mounting platform 5. The rotation center of the central gear 7 coincides with the rotation center of the rotating component 3. The two transmission gears 8 are arranged opposite each other and mesh with the central gear 7 and the first gear tooth 42, respectively. The central gear 7 and the two transmission gears 8 serve to position the rotating component 3, making its rotation more stable. Simultaneously, when the rotating component 3 rotates, the central gear 7 rotates synchronously. Through the meshing of the two transmission gears 8 with the central gear 7 and the first gear tooth 42, the rotational power of the rotating component 3 can be transmitted more evenly to the first gear tooth 4, making the overall rotation of the rotating component 3 more stable.

[0034] Specifically, such as Figures 5 to 7As shown, the mounting platform 5 has two opposing arc-shaped protrusions 52 on the side facing the base 2. A first mounting groove 51 is formed on the side of one of its arc-shaped protrusions corresponding to the first gear tooth 42. A second mounting groove 53 is defined between the two arc-shaped protrusions 52, and two first slots 54 are defined between their ends. The spindle gear 7 is rotatably mounted in the second mounting groove 53, and the two transmission gears 8 are rotatably mounted in the first slots 54. The clever spatial arrangement of the second mounting groove 53 and the two first slots 54 between the two opposing arc-shaped protrusions 52 fully utilizes the limited space of the mounting platform 5, allowing the spindle gear 7 and the two transmission gears 8 to be installed in their respective second mounting grooves 53 and first slots 54, reducing the volume and space occupied by the mounting platform 5 and making the entire bracket structure more compact. The shapes of the second mounting groove 53 and the first slots 54 can match the shapes of the spindle gear 7 and the two transmission gears 8.

[0035] Furthermore, the bracket also includes a rotating platform 9, which is connected to the mounting platform 5 and the spindle gear 7 via a first fitting port 31 on one side of the rotating component 3. The rotating platform 9, mounting platform 5, and spindle gear 7 are connected, and when the spindle gear 7 rotates, it drives the rotating platform 9 to rotate as well, thus allowing the rotating platform 9 to rotate along with the rotating component 3. For example, other accessories or stickers can be mounted on the rotating platform 9 for decoration. The connection between the rotating platform 9 and the spindle gear 7 ensures the proper installation of both.

[0036] Specifically, the shaft gear 7 has an annular rib 71 on the side facing the base 2. The annular rib 71 can abut against the base 2, reducing the contact area between the shaft gear 7 and the base 2, reducing friction, and improving the smoothness of the rotation of the shaft gear 7.

[0037] Both first slots 54 are equipped with mounting posts 55, on which the transmission gear 8 is rotatably mounted. The mounting posts 55 provide robust support for the transmission gear 8. During rotation of the transmission gear 8, the mounting posts 55 bear the radial and axial forces from the gear, preventing the transmission gear 8 from wobbling, shifting, or falling off. The structural strength and rigidity of the mounting posts 55 provide strong support for the transmission gear 8, enabling it to withstand greater torque and load.

[0038] A limiting ring 72 is provided on the side of the spindle gear 7 facing away from the base 2. A first opening 56 is provided on the second mounting groove 53, and the limiting ring 72 is fitted into the first opening 56. A connecting part 91 is provided on the rotary table 9, and the connecting part 91 is inserted into the limiting ring 72 to connect with the spindle gear 7. The limiting ring 72, fitted into the first opening 56 of the mounting table 5, plays a good limiting role for the spindle gear 7. During the use of the bracket, the spindle gear 7 is not prone to axial movement, ensuring the stability and reliability of the spindle gear 7 transmission. The connecting part 91 on the rotary table 9 is inserted into the limiting ring 72 to connect with the spindle gear 7. The connecting part 91 can be installed on the spindle gear 7 with screws, or it can be connected to the spindle gear 7 by interference fit with the limiting ring 72. The connection can be achieved by conventional technical means, which will not be described in detail here.

[0039] Furthermore, the arc-shaped boss 52 has a mounting post 521 on the side facing the base 2, and the base 2 has a mounting hole 21, in which the mounting post 521 is inserted. The arc-shaped boss 52 can be connected to the base 2 by the mounting post 521 being inserted into the mounting hole 21, and the mounting post 521 and the mounting hole 21 can be connected and fixed by an interference fit. There are at least two mounting posts 521 and at least two mounting holes 21.

[0040] The positioning block 61 has a V-shaped protruding end 611. Driven by the elastic force of the elastic element, the protruding end 611 extends out of the first mounting groove 51 and engages with the first gear tooth 42. The V-shaped protruding end 611 design results in a relatively small contact area between the positioning block 61 and the first gear tooth 42, but the contact points are more concentrated and precise, facilitating the insertion of the positioning block 61 into the first gear tooth 42. When the elastic element drives the positioning block 61 to extend, the V-shaped protruding end 611 can accurately engage with the tooth groove of the first gear tooth 42, achieving precise positioning of the rotating part 3. After the V-shaped protruding end 611 engages with the gear tooth, its two inclined surfaces fit tightly against the tooth surface of the first gear tooth 42, forming a stable locking structure.

[0041] like Figure 7 As shown, the opening of the first mounting groove 51 is provided with abutment edges 511 extending toward the center of the opening on both sides, and the abutment edges 511 abut against the two sides of the protruding end 611. The abutment edges 511 are located on both sides of the opening of the first mounting groove 51 and extend toward the center, which can effectively abut against the two sides of the V-shaped protruding end 611 of the positioning block 61, preventing the positioning block 61 from falling out of the first mounting groove 51 under the elastic force of the elastic member.

[0042] The support assembly 1 includes a rotating arm 11 and a support plate 12. Both ends of the rotating arm 11 are rotatably connected to the rotating component 3 and the support plate 12, respectively. The support plate 12 has multiple heat dissipation holes 121. This structure allows the support plate 12 to be adjusted relative to the rotating component 3 at multiple angles. Users can flexibly adjust the angle of the support plate 12 according to actual needs and usage scenarios to achieve the best viewing or usage effect. The rotatable connection between the rotating arm 11 and the rotating component 3, as well as the rotatable connection between the rotating arm 11 and the support plate 12, can be achieved using conventional rotating shafts, which will not be elaborated further here.

[0043] The support plate 12 is used to support electronic devices such as mobile phones. Two support arms 122 are provided along the bottom edge of the support plate 12 to support the bottom of the electronic device. Multiple heat dissipation holes 121 provided on the support plate 12 can effectively promote heat exchange between the electronic device and the surrounding air, and improve the heat dissipation effect.

[0044] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
