[0002] With the development of technology, personal portable electronic products such as laptops and tablets are widely used in daily life. However, the limited size of portable electronic products often necessitates the use of stands for support to flexibly adapt to different usage scenarios.

Detailed Implementation
[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0030] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0031] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.
[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0033] With the development of technology, personal portable electronic products such as laptops and tablets are widely used in daily life. However, the limited size of portable electronic products often necessitates the use of stands for support to flexibly adapt to different usage scenarios. Stands on the market use motors to adjust the angle of the support plate, thus allowing for screen angle adjustment. On the one hand, because electronic products have a certain weight, the motor requires a large torque to start, often resulting in a large motor size, which is inconvenient for space layout. On the other hand, current motors adjust a large angle with each start, making fine-tuning difficult and affecting the user experience.
[0034] To solve the above problems, refer to Figure 1 The tilting mechanism of the bracket according to the first aspect embodiment of this utility model includes a support arm 100 and a swing device 110. The support arm 100 has a first support 101, on which a fixed shaft 103 and a fixed wheel 102 are provided. The fixed shaft 103 is fixedly installed on the first support 101, and the fixed wheel 102 is fixedly installed on the first support 101. It can be understood that the fixed wheel 102 is a gear. The swing device 110 includes a housing 114, a second support 106, a carrier plate 112, a motor 111, and a transmission wheel set 120. The housing 114 is pivotally connected to the fixed shaft 103, the second support 106 is fixedly connected to the carrier plate 112, and the carrier plate 112 is fixedly connected to the housing 114. The motor 111 is installed inside the housing 114, and the transmission wheel set 120 is installed inside the second support 106. It is understood that the output shaft of the motor 111 is equipped with an output wheel 128, which meshes with the fixed wheel 102. The motor 111 drives the transmission wheel set 120 to rotate, and causes the output wheel 128 to rotate relative to the fixed wheel 102, thereby causing the carrier plate 112 to rotate relative to the first support 101 to achieve angle adjustment. It is also understood that the transmission wheel set 120 includes multiple reduction wheel sets, in which the outer diameter of the driving wheel is smaller than the outer diameter of the driven wheel, thus achieving the effect of reducing the speed of the motor 111 and increasing its torque. Furthermore, the multiple reduction wheel sets further reduce the speed of the motor 111 and increase its torque, allowing for the use of a smaller motor 111 while maintaining the same torque, which is beneficial for achieving a compact space layout. Moreover, it reduces the angle adjusted by the motor 111 in a single start, facilitating fine-tuning of the angle of the carrier plate 112, which improves usability and user experience.
[0035] Reference Figure 3It is understood that the housing 114 covers the outer periphery of the swing device 110, and a limiting block 104 is provided on the fixed shaft 103. A limiting groove 105 is provided on the outer periphery of the limiting block 104. The limiting groove 105 extends circumferentially along the fixed shaft 103. A protrusion 115 is provided on the inner peripheral wall of the housing 114. The protrusion 115 can rotate around the fixed shaft 103 within the limiting groove 105. When the housing 114 rotates relative to the first support 101 and reaches a certain preset extreme point, the side wall of the protrusion 115 can press against one side of the inner wall of the limiting groove 105 along the circumferential direction of the fixed shaft 103, thereby preventing the protrusion 115 from continuing to move. This achieves the limitation of the rotation angle of the housing 114 and the carrier plate 112, avoiding the risk of electronic products falling due to excessive rotation of the carrier plate 112.
[0036] Specifically, refer to Figure 2 The transmission wheel assembly 120 includes a first transmission wheel 121, a second transmission wheel 122, a third transmission wheel 123, and a fourth transmission wheel 124. The first transmission wheel 121 and the third transmission wheel 123 rotate coaxially, as do the second transmission wheel 122 and the fourth transmission wheel 124, which helps to reduce the space occupied and improve the compactness of the spatial layout. Furthermore, the first transmission wheel 121 includes a first tooth 1211 and a second tooth 1212, the second transmission wheel 122 includes a third tooth 1221 and a fourth tooth 1222, and the third transmission wheel 123 includes a fifth tooth 1231 and a sixth tooth 1232. It is understood that the first tooth section 1211, the second tooth section 1212, the third tooth section 1221, the fourth tooth section 1222, the fifth tooth section 1231, the sixth tooth section 1232, and the fourth transmission wheel 124 are all gears. Furthermore, the second tooth section 1212, the third tooth section 1221, the fourth tooth section 1222, the fifth tooth section 1231, the sixth tooth section 1232, and the fourth transmission wheel 124 are all helical gears. Since the teeth of the helical gear gradually enter and exit the mesh, the impact load can be reduced, the transmission is smoother, and the noise level during operation is reduced. In addition, the contact area between the two meshing teeth of the helical gear is larger, which can withstand a higher load than that of the spur gear, thereby improving the transmission stability of the transmission wheel set 120.
[0037] It is understood that the first tooth 1211 and the second tooth 1212 are coaxial and rotate synchronously, with the outer diameter of the first tooth 1211 being larger than that of the second tooth 1212. Similarly, the third tooth 1221 and the fourth tooth 1222 are coaxial and rotate synchronously, with the outer diameter of the third tooth 1221 being larger than that of the fourth tooth 1222. The fifth tooth 1231 and the sixth tooth 1232 are coaxial and rotate synchronously, with the outer diameter of the fifth tooth 1231 being larger than that of the sixth tooth 1232. Finally, the fourth transmission wheel 124 and the output wheel 128 are coaxial and rotate synchronously, with the outer diameter of the fourth transmission wheel 124 being larger than that of the output wheel 128. It is understandable that the "outer diameter" of the first tooth 1211 is the maximum outer diameter of the first tooth 1211, which is twice the maximum value of the distance between the outer peripheral wall of the tooth on the outer circumference of the first tooth 1211 and the rotation axis of the first tooth 1211. Similarly, the outer diameters of the second tooth 1212, the third tooth 1221, the fourth tooth 1222, the fifth tooth 1231, the sixth tooth 1232, the fourth transmission wheel 124, and the output wheel 128 are their respective maximum outer diameters, which will not be elaborated here.
[0038] It is understood that the first tooth 1211, the second tooth 1212, the third tooth 1221, the fourth tooth 1222, the fifth tooth 1231, the sixth tooth 1232, the fourth drive wheel 124, and the output wheel 128 can be fixed by integral molding or by assembly.
[0039] Reference Figure 2 It is understood that the reduction gear set includes a first gear set 125, a second gear set 126, and a third gear set 127. The first gear set 125 includes a second toothed section 1212 and a third toothed section 1221 that mesh with each other. It is understood that the outer diameter of the second toothed section 1212 is smaller than the outer diameter of the third toothed section 1221, thereby achieving the transmission reduction function, which is beneficial to improving the transmission torque of the motor 111 and reducing the rotation angle adjusted by the motor 111 in a single start. The second gear set 126 includes a fourth toothed section 1222 and a fifth toothed section 1231 that mesh with each other. It is understood that the outer diameter of the fourth toothed section 1222 is smaller than the outer diameter of the fifth toothed section 1231, thereby achieving the transmission reduction function, which is beneficial to improving the transmission torque of the motor 111 and reducing the rotation angle adjusted by the motor 111 in a single start. The third gear set 127 includes a sixth tooth 1232 and a fourth transmission wheel 124 that mesh with each other. It is understood that the outer diameter of the sixth tooth 1232 is smaller than the outer diameter of the fourth transmission wheel 124, thereby realizing the transmission speed reduction function. This is beneficial to increasing the transmission torque of the motor 111 and reducing the rotation angle adjusted by the motor 111 in a single start, which is beneficial to improving the flexibility of adjustment.
[0040] It is understandable that the fourth transmission wheel 124 and the output wheel 128 are coaxial and rotate synchronously, with the outer diameter of the fourth transmission wheel 124 being larger than that of the output wheel 128. Simultaneously, the outer diameter of the output wheel 128 is smaller than that of the fixed wheel 102, thus achieving deceleration when the output wheel 128 outputs power to the fixed wheel 102. It is also understandable that the rotational angular velocity of the fourth transmission wheel 124 is the same as that of the output wheel 128, and since the outer diameter of the fourth transmission wheel 124 is larger than that of the output wheel 128, the linear velocity on the outer circumference of the output wheel 128 is less than that of the fourth transmission wheel 124. This achieves the deceleration function when the fourth transmission wheel 124 drives the fixed wheel 102, which is beneficial for increasing the torque of the motor 111 and reducing the angle adjusted during a single start-up of the motor 111, facilitating fine-tuning.
[0041] The electronic device according to the second aspect of this utility model includes the aforementioned bracket flipping mechanism. It is understood that the electronic device incorporates all the technical features of the bracket flipping mechanism, and therefore the electronic device possesses at least all the beneficial effects of the bracket flipping mechanism.
[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
