Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a new electric hinge structure. Background Art

[0002] The patent application number is: 202410882347.7, and the patent name is: A Chinese invention patent application for a rotating shaft module and an electronic device, which specifically discloses an electric rotating shaft (hinge); specifically, the rotating shaft module includes a driving component, a rotating component and a rotating shaft composed of a driving shaft and a driven shaft, the rotating component includes a connecting part, a rotating part rotatably sleeved on the periphery of the rotating shaft, and a torsion structure is provided on both sides of the rotating part. There is a clamping damping force along the axial direction of the rotating shaft between the torsion structure and the rotating part of the rotating component. Under the action of the clamping damping force, a torsion force is formed between the torsion structure and the rotating component; the rotating component is configured to rotate synchronously with the rotating shaft or to rotate relative to the rotating shaft; the rotating shaft module also includes a locking component, which is sleeved on the periphery of the rotating shaft and applies a locking force to the torsion structure and the rotating part of the rotating component along the axial direction of the rotating shaft; the driving component includes a driving motor and a reduction gearbox, the driving motor has a driving shaft, and the ratio of the input speed of the driving shaft to the output speed of the rotating shaft is the reduction ratio of the reduction gearbox.

[0003] For the above-mentioned rotating shaft module, when the rotating part is electrically rotated, the driving motor drives the rotating shaft to rotate after being decelerated by the reduction gear box. The locking force applied by the locking part causes a torque generated by friction between the rotating part of the rotating part and the rotating shaft. The torque causes the rotating part to rotate synchronously with the rotating shaft.

[0004] It should be pointed out that the above-mentioned shaft module has the following defects. Specifically, when the reduction gearbox realizes the reduction transmission, due to the objectively existing transmission gaps, these gaps will cause the shaft to swing. This phenomenon will be reflected in the equipment installed on the rotating part, causing the equipment to shake. Therefore, the above-mentioned shaft module has the problem of poor stability and reliability. Utility Model Content

[0005] The purpose of the utility model is to provide a new electric hinge structure to address the deficiencies of the existing technology. The new electric hinge structure has a novel design, good stability and reliability, and can effectively avoid shaking.

[0006] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions.

[0007] A novel electric hinge structure includes a drive motor, a reduction gearbox, a rotating shaft, a rotating member, a first torque structure, and a first locking nut. The drive motor is fastened to the housing of the reduction gearbox, the power output shaft of the drive motor is connected to the input end of the reduction gearbox, and the output end of the reduction gearbox is connected to the rotating shaft.

[0008] The rotating member is provided with a rotating portion and a connecting portion, and the rotating shaft is provided with a first shoulder. The rotating portion of the rotating member, the first torsion structure, and the first locking nut are sequentially mounted on the outer periphery of the rotating shaft from back to front, and the first locking nut is threadedly connected to the rotating shaft. Friction is generated between the rotating portion of the rotating member and the first torsion structure.

[0009] The housing of the reduction gearbox is fastened with an auxiliary bracket mounted on the periphery of the rotating shaft. The periphery of the rotating shaft is equipped with a second torsion structure between the auxiliary bracket and the first shoulder, and a second locking nut located in front of the second torsion structure. The second locking nut is threadedly connected to the rotating shaft, and there is friction between the second torsion structure and the auxiliary bracket.

[0010] The auxiliary bracket includes a bracket fixing portion and a bracket sleeve portion. The bracket fixing portion and the bracket sleeve portion are an integrated structure. The bracket fixing portion is screwed and fastened to the housing of the reduction gearbox, and the bracket sleeve portion is sleeved around the outer periphery of the rotating shaft.

[0011] The rotating shaft is provided with a second shoulder at the rear side of the bracket sleeve portion of the auxiliary bracket, and a friction gasket sleeved on the outer periphery of the rotating shaft is installed between the second shoulder and the bracket sleeve portion, and the friction gasket is clamped between the second shoulder and the bracket sleeve portion.

[0012] Wherein, the friction gasket is anti-rotationally sleeved on the periphery of the rotating shaft.

[0013] Wherein, the rotating shaft is rotatably mounted on the housing of the reduction gearbox through a bearing.

[0014] Compared to the prior art, the present invention has the following beneficial effects: The friction between the second torsion structure and the auxiliary bracket generates a torsion force that must be overcome for the rotating shaft to swing, and when the rotating shaft rotates to the desired position, the torsion force locks the rotating shaft in the desired position. Therefore, the torsion force effectively prevents the rotating shaft from swinging due to transmission clearance in the reduction gearbox, and further effectively prevents the structural components mounted on the connecting portion of the rotating member from vibrating, thereby improving stability and reliability. Therefore, the novel electric hinge structure of the present invention has the advantages of novel structural design, good stability and reliability, and can effectively prevent vibrating.

DETAILED DESCRIPTION

[0021] The present invention will be described below in conjunction with specific implementation methods.

[0022] Example 1, as Figures 1 to 3 As shown, a novel electric hinge structure includes a drive motor 1, a reduction gearbox 2, a rotating shaft 3, a rotating member 4, a first torsion structure 51, and a first locking nut 61. The drive motor 1 is fastened to the housing 21 of the reduction gearbox 2. The power output shaft of the drive motor 1 is connected to the input end of the reduction gearbox 2, and the output end of the reduction gearbox 2 is connected to the rotating shaft 3. The rotating shaft 3 is rotatably mounted to the housing 21 of the reduction gearbox 2 via a bearing 9.

[0023] Further, such as Figures 1 to 3 As shown, the rotating part 4 is provided with a rotating portion 41 and a connecting portion 42, and the rotating shaft 3 is provided with a first shoulder 31. The rotating portion 41 of the rotating part 4, the first torsion structure 51 and the first locking nut 61 are sequentially mounted on the periphery of the rotating shaft 3 from back to front, and the first locking nut 61 is threadedly connected to the rotating shaft 3. There is friction between the rotating portion 41 of the rotating part 4 and the first torsion structure 51.

[0024] Furthermore, Figures 1 to 3 As shown, the housing 21 of the reduction gear box 2 is fastened with an auxiliary bracket 7 mounted on the periphery of the rotating shaft 3. A second torsion structure 52 and a second locking nut 62 located in front of the second torsion structure 52 are mounted on the periphery of the rotating shaft 3 between the auxiliary bracket 7 and the first shoulder 31. The second locking nut 62 is threadedly connected to the rotating shaft 3, and there is friction between the second torsion structure 52 and the auxiliary bracket 7.

[0025] It should be explained that the rotating shaft 3 is provided with external threads at positions corresponding to the first locking nut 61 and the second locking nut 62, and the first locking nut 61 and the second locking nut 62 are screwed onto the external threads at corresponding positions.

[0026] As for the first torsion structure 51 and the second torsion structure 52 of the first embodiment, the torsion structure form is already in the prior art and will not be described in detail here.

[0027] When the new electric hinge structure of the first embodiment realizes electric movement, the driving motor 1 drives the rotating shaft 3 to rotate after being decelerated by the reduction gear box 2. The locking force generated by the first locking nut 61 causes friction to be generated between the first torsion structure 51 and the rotating part 41 of the rotating member 4, thereby generating a first torsion effect. Under the action of the first torsion, the rotating member 4 rotates synchronously with the rotating shaft 3, thereby realizing electric movement.

[0028] It should be pointed out that the locking force generated by the second locking nut 62 causes friction between the second torsion structure 52 and the auxiliary bracket 7, thereby generating a second torsion. Under the action of the second torsion, the rotating shaft 3 must overcome the second torsion to swing, and when the rotating shaft 3 rotates to the desired position, the second torsion will lock the rotating shaft 3 at the desired position; therefore, the above-mentioned second torsion can effectively prevent the rotating shaft 3 from swinging due to the transmission gap of the reduction gear box 2, and thus can effectively prevent the structural parts installed on the connecting part 42 of the rotating part 4 from shaking, and has good stability and reliability.

[0029] In summary, it can be seen that, through the above structural design, the new electric hinge structure of the first embodiment has the advantages of novel structural design, good stability and reliability, and can effectively avoid the shaking phenomenon.

[0030] Example 2, as Figures 1 to 3 As shown, the difference between this embodiment 2 and embodiment 1 is that the auxiliary bracket 7 includes a bracket fixing portion 71 and a bracket sleeve portion 72. The bracket fixing portion 71 and the bracket sleeve portion 72 are an integrated structure. The bracket fixing portion 71 is screwed and fastened to the housing 21 of the reduction gearbox 2, and the bracket sleeve portion 72 is sleeved on the periphery of the rotating shaft 3.

[0031] Example 3, as Figure 3 As shown, the difference between the third embodiment and the second embodiment is that the rotating shaft 3 is provided with a second shoulder 32 on the rear side of the bracket sleeve portion 72 of the auxiliary bracket 7, and a friction gasket 8 is installed between the second shoulder 32 and the bracket sleeve portion 72 and is sleeved on the outer periphery of the rotating shaft 3. The friction gasket 8 is clamped between the second shoulder 32 and the bracket sleeve portion 72.

[0032] The friction pad 8 is mounted on the outer periphery of the rotating shaft 3. It should be explained that the third embodiment can achieve the anti-rotation connection between the friction pad 8 and the rotating shaft 3 in the following manner: the center hole of the friction pad is a flat hole, and the corresponding mounting position of the rotating shaft 3 is a flat structure.

[0033] For the friction gasket 8 of the third embodiment, when the bracket fixing part 71 of the auxiliary bracket 7 is screwed and fixed to the housing 21 of the reduction gear box 2, the friction gasket 8 is pressed. At this time, there is friction between the friction gasket 8 and the bracket sleeve part 72 of the auxiliary bracket 7. This friction can further increase the torque of the rotating shaft 3 when preventing it from swinging, thereby further improving the stability and reliability.

[0034] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
