However, rotating the display screen relative to the chassis still requires manual operation, forcing users to rely on feel to control the screen's rotation angle. This makes precise control of the screen's rotation angle difficult, impacting the user experience. Utility Model Content

[0028] In the description of this utility model, the use of "first" and "second" 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 technical features or the order of the technical features.

[0029] 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.

[0030] The following is for reference. Figures 1 to 3 A hinge module according to the first aspect of this utility model will be described in detail.

[0031] refer to Figures 1 to 3 According to an embodiment of the present invention, an articulated module includes a drive structure 100, a rotating shaft, a transmission structure 200, and a detection structure 300. The drive structure 100 has a transmission shaft 121. The rotating shaft is located on one radial side of the transmission shaft 121 and is parallel to the transmission shaft 121. The rotating shaft is used for rotatable connection with the body and for fixed connection with the display screen. The input end of the transmission structure 200 is connected to the transmission shaft 121, and the output end of the transmission structure 200 is connected to the rotating shaft. The transmission structure 200 is located on the same side as the transmission shaft 121 and the rotating shaft. The detection structure 300 is located on one side of the rotating shaft and is electrically connected to the drive structure 100. The detection structure 300 is used to detect the rotation angle of the rotating shaft.

[0032] In the hinge module of this application, the drive structure 100 drives the transmission shaft 121 to rotate. Since the transmission shaft 121 is connected to the input end of the transmission structure 200, and the output end of the transmission structure 200 is connected to the rotating shaft, the transmission shaft 121 drives the rotating shaft to rotate through the transmission structure 200. At the same time, the detection structure 300 detects the rotation angle of the rotating shaft. When the rotating shaft rotates to a preset angle, the detection structure 300 controls the drive structure 100 to stop the rotation of the transmission shaft 121. When the hinge module of this application is applied to a laptop computer, the hinge module is installed on the laptop computer body, and the rotating shaft is fixedly connected to the laptop computer display screen. The transmission shaft 121 of the drive structure 100 drives the rotating shaft to rotate through the transmission structure 200, thereby causing the display screen to rotate relative to the body. When the detection structure 300 detects that the rotating shaft has rotated to a preset angle, the drive structure 100 stops driving the transmission shaft 121 according to the detection structure 300, so that the rotation angle of the display screen relative to the body can be precisely adjusted.

[0033] It is understood that by placing the rotating shaft on one radial side of the transmission shaft 121 and placing the transmission shaft 121 and the rotating shaft on the same side of the transmission structure 200, the space occupied by the entire hinge module in the axial direction of the transmission shaft 121 is reduced, thereby improving the structural compactness of the hinge module of this application.

[0034] refer to Figure 2 and Figure 3 In some embodiments of this utility model, the detection structure 300 includes a mounting base 310, a potentiometer 320, and a detection gear 330. The gear shaft of the detection gear 330 is rotatably mounted on the mounting base 310, and the detection gear 330 is connected to the transmission structure 200. The potentiometer 320 is mounted on the mounting base 310 and is used to detect the rotation angle of the gear shaft of the detection gear 330. The potentiometer 320 is electrically connected to the drive structure 100.

[0035] It is understood that the drive shaft 121 of the drive structure 100 drives the detection gear 330 to rotate through the drive structure 200, thereby driving the gear shaft to rotate. Then, the rotation angle of the gear shaft of the detection gear 330 is detected by the potentiometer 320 to indirectly detect the rotation angle of the shaft. When the potentiometer 320 detects that the gear shaft of the detection gear 330 has rotated to a preset angle, the drive structure 100 can stop the drive of the drive shaft 121 according to the detection result of the potentiometer 320.

[0036] Understandably, the potentiometer 320 is inexpensive, has high detection accuracy, and is small in size, making it easy to install.

[0037] like Figure 3As shown, in some embodiments, the mounting base 310 includes a base body 311 and a limiting member 312. Two limiting members 312 are spaced apart on the base body 311. The base body 311 and the two limiting members 312 together define a mounting through groove. The potentiometer 320 is detachably mounted in the mounting through groove along the extension direction of the mounting through groove. The limiting member 312 has a limiting portion 312a at one end away from the base body 311. The limiting portion 312a abuts against the end of the potentiometer 320 away from the base body 311 to prevent the potentiometer 320 from disengaging from the mounting through groove in the direction away from the base body 311.

[0038] Understandably, when installing potentiometer 320, the operator can push potentiometer 320 into the mounting slot along the extension direction of the mounting slot, thereby installing potentiometer 320 on mounting base 310; when removing potentiometer 320, the operator can pull potentiometer 320 out of the mounting slot along the extension direction of the mounting slot, thereby removing potentiometer 320 from mounting base 310.

[0039] It is understandable that by providing two limiting members 312 on the mounting base 310, and by detachably mounting the potentiometer 320 in the mounting through groove formed by the base 311 and the two limiting members 312, the installation and removal of the potentiometer 320 on the mounting base 310 becomes simpler and more convenient.

[0040] refer to Figure 2 In some embodiments of this utility model, the transmission structure 200 includes a reduction gear set 210 and an output shaft 220. One end of the output shaft 220 is fitted with a transmission gear 221, and the other end of the output shaft 220 is connected to a rotating shaft. The input end of the reduction gear set 210 is connected to the transmission shaft 121, and the output end of the reduction gear set 210 is connected to the transmission gear 221.

[0041] It is understandable that the drive shaft 121 of the drive structure 100 is connected to the transmission gear 221 through the reduction gear set 210. Under the premise that the power of the drive structure 100 is constant, the output shaft 220 can output a larger torque, and correspondingly, the rotating shaft can output a larger torque, so that when the hinge module of this application is applied to a laptop, the rotating shaft can drive the display screen to rotate more smoothly. Correspondingly, under the premise that the output torque of the rotating shaft is constant, the drive structure 100 can select a smaller power specification to reduce the size and cost of the drive structure 100.

[0042] like Figure 2As shown, in some embodiments, the reduction gear set 210 includes a plurality of reduction units 211 connected in sequence. Each reduction unit 211 includes an input gear 211a and an output gear 211b that mesh with each other. Between any two adjacent reduction units 211, the input gear 211a of one reduction unit 211 and the output gear 211b of the other reduction unit 211 are arranged to rotate synchronously.

[0043] It is understood that the reduction gear set 210 includes multiple reduction units 211 connected in sequence. Each reduction unit 211 has a certain reduction ratio. The setting of multiple reduction units 211 can further improve the reduction ratio between the transmission shaft 121 and the rotating shaft, so that the rotating shaft can output greater torque.

[0044] like Figure 2 As shown, in some embodiments, the transmission structure 200 further includes a first driven shaft 230 and a second driven shaft 240. In each reduction unit 211, the input gear 211a is rotatably mounted on the first driven shaft 230, and the output gear 211b is rotatably mounted on the second driven shaft 240. It is understood that by rotatably mounting the input gears 211a of multiple reduction units 211 on the first driven shaft 230 and rotatably mounting the output gears 211b of multiple reduction units 211 on the second driven shaft 240, the space occupied by the reduction gear set 210 in the radial direction of the first driven shaft 230 is reduced, thereby making the overall structure of the transmission structure 200 more compact.

[0045] like Figure 2 As shown, in some embodiments, the first driven shaft 230 is coaxially arranged with the drive shaft 121. It can be understood that by coaxially arranging the first driven shaft 230 with the drive shaft 121, the axial space of the drive shaft 121 is fully utilized, making the overall structure of the reduction gear set 210 more compact.

[0046] like Figure 2 As shown, in some embodiments, a second driven shaft 240 is disposed between the transmission shaft 121 and the output shaft 220. A first driven gear 241 is provided on the second driven shaft 240, and the output end of the reduction gear set 210 is connected to the transmission gear 221 through the first driven gear 241. It can be understood that by disposing the second driven shaft 240 between the transmission shaft 121 and the output shaft 220, there is a sufficient distance between the rotating shaft and the drive structure 100 in the radial direction to reduce interference between the rotating shaft and the drive structure 100. When the hinge module of this application is subsequently applied to a laptop computer, there can be a sufficient distance between the display screen and the drive structure 100 to reduce the probability of interference between the display screen and the drive structure 100.

[0047] like Figure 2 As shown, in one embodiment, the hinge module further includes a third driven shaft 250, which is disposed between the second driven shaft 240 and the output shaft 220. A second driven gear 251 is provided on the third driven shaft 250, and the second driven gear 251 meshes with the first driven gear 241 and the transmission gear 221, respectively. It is understood that by providing the third driven shaft 250 between the second driven shaft 240 and the output shaft 220, the distance between the pivot and the drive structure 100 can be further increased, thereby reducing the probability of interference between the display screen and the drive structure 100 after the hinge module of this application is applied to a laptop computer.

[0048] refer to Figure 1 and Figure 2 In some embodiments of this utility model, the drive structure 100 includes a motor 110 and a planetary reducer 120 connected together. The motor 110 is electrically connected to the detection structure 300, and the output end of the planetary reducer 120 forms a drive shaft 121. It is understood that by connecting the output end of the motor 110 to the input end of the planetary reducer 120, and with the output end of the planetary reducer 120 forming the drive shaft 121, the planetary reducer 120 reduces the rotational speed of the drive shaft 121, thereby increasing the torque of the drive shaft 121.

[0049] The following is a detailed description of a laptop computer according to a second aspect embodiment of the present invention.

[0050] A laptop computer according to a second aspect embodiment of the present invention includes a hinge module as described in the first aspect embodiment. The laptop computer also includes a display screen and a body. The display screen is fixedly connected to a hinge, and the hinge is rotatably connected to the body. By setting the hinge module on the body of the laptop computer, the hinge is rotatably configured relative to the body and fixedly connected to the display screen. The drive shaft 121 of the drive structure 100 drives the hinge to rotate through the drive structure 200, thereby causing the display screen to rotate relative to the body. When the detection structure 300 detects a preset angle of rotation of the hinge, the drive structure 100 stops driving the drive shaft 121 according to the detection structure 300, thereby enabling precise adjustment of the rotation angle of the display screen relative to the body.
