Description

The automatic rotating shaft of miniaturization

Technical field

The utility model relates to a kind of rotating shaft, relates in particular to the automatic rotating shaft of miniaturization that a kind of base that is used for flat panel TV and IT display device is realized automatically controlled deflection.

Background technique

Masses are light, thin to flat panel TV and IT display device in order to satisfy, the demand of hommization, according to coming with LCD, PDP in the recent period is the appearance and modeling characteristics of the flat panel TV and the IT display device of representative, the automatic rotating shaft of a kind of miniaturization of ad hoc meter, make under the control of remote controller or control switch, the relative longitudinal shaft with base of the screen of flat panel TV or IT display device is done the left rotation and right rotation motion, adjust visual angle, adapt to different occasion diverse location people's impression needs.

At present, the big or complex structure of the overall volume of automatic rotating shaft, very fast decline after rising before making the application of automatic rotating shaft on the flat panel TV base by the several years is because the final consumption masses obviously strengthen sense organ demand frivolous, low noise at present.But rotating shaft application demand on flat panel TV is still very vigorous automatically, though the flat panel TV that can satisfy the automatic spinfunction of sense organ demand exceeds a little than base-fixed flat panel TV price, but it is worth that people still think, is worth overpaying expense for this function.

Therefore, present many manufacturers begin to be devoted to study applied widely, possess the automatic rotating shaft of base frivolous, the low noise feature.Rotating shaft in this target is at first satisfied and is being realized the left rotation and right rotation function under the controlled conditions automatically; The second, volume is little, and desired value is lower than 63 * 104 millimeters (oval short major axis numerical value) for diameter is installed; The 3rd, can realize the assembly structure compatibility of fixed and this automatic rotary function.

The model utility content

The utility model reaches baroque defective more greatly in order to solve existing automatic rotating shaft overall volume, provide a kind of miniaturization automatic rotating shaft, it adopts zero motor as drive motor, simultaneously in conjunction with the revolute pair of being with body cradle and bearing pin, it is simple and reliable for structure, volume is less, can effectively realize rotating function.

For solving the problems of the technologies described above, the utility model adopts following technological scheme: the automatic rotating shaft of a kind of miniaturization comprises base support and is arranged on the revolute pair on base support top.The bottom is provided with the zero motor that matches with revolute pair in the described base support.

Described zero motor comprises a speed reducer, and a side is provided with the motor that is connected as a single entity with it above speed reducer, and opposite side then is provided with output shaft.

Described revolute pair includes a body cradle and a base support fixed plate that is connected with base support; Be provided with below body cradle and the suitable groove of the output shaft of zero motor, the body cradle top is connected with bearing pin; Described bearing pin at kink in the base support fixed plate.

Described revolute pair also includes complete machine fixed plate, collar, spring washer, wrist pad two, plain cushion, wrist pad one and the nut that cooperates with bearing pin successively.

The utility model it adopt zero motor as drive motor, compact structure, to produce noise little, zero motor cooperates the revolute pair of band body cradle and bearing pin to carry out transmission simultaneously, and overall structure is simple, reliable performance, has simultaneously at the assurance rotating function and reduces volume.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further:

Fig. 1 is the utility model assembly exploded perspective view;

Fig. 2 is the utility model three-dimensional view;

Fig. 3 is a zero motor three-dimensional view in the utility model.

Embodiment

For realizing miniaturization, at first zero motor is carried out type selecting, its principle is: can realize that low speed and large torque, boundary dimension are less, attachment face and output shaft, outbound course be reasonable.The selected zero motor of the utility model as shown in Figure 3, it comprises speed reducer 6 and is positioned at speed reducer 6 tops and motor 5 that is connected as a single entity with it and output shaft 4.Because zero motor carries speed reducer 6, common electric machine can be realized the miniaturization of volume, and make operating noise be in acceptable amount in decibels under the indoor environment in conjunction with the scheme of self-control reducing gear relatively.

As shown in Figure 1 and Figure 2, the automatic rotating shaft of the utility model miniaturization mainly is made up of zero motor 3, base support 2, revolute pair 1 three big parts.Wherein, revolute pair 1 is divided into base support fixed plate 13, body cradle 14, complete machine fixed plate 12, set screw nut 7, bearing pin 15, bowl pad one 8a, bowl pad two 8b, collar 11, spring washer 10, plain cushion 9.Described body cradle 14 belows are provided with and the suitable groove of the output shaft of zero motor, and body cradle 14 upper fixed have bearing pin 15.During assembled, directly be fixed to zero motor 3, base support 2 on the base substrate earlier; When fixing revolute pair 1, body cradle 14 is inserted in the output shaft 3 of zero motor in advance, the base support fixed plate 13 with revolute pair is fixed on the base support 2 again; The base that utilizes the fixed structure of complete machine fixed plate 12 will have this rotating shaft at last is fixed to complete machine, realizes final assembly.

During critical component revolute pair 1 assembled as shown in Figure 1, earlier bearing pin 15 is inserted in body cradle 14, successively base support fixed plate 13, complete machine fixed plate 12 are inserted in again, at last collar 11, spring washer 10, bowl pad one 8a, plain cushion 9, bowl pad two 8b, nut 7 are inserted in successively that (bowl pad one becomes the concave surface relative status when assembling with bowl pad two, show as Fig. 1), the locking degree of adjusting nut 7 realizes the adjusting of moment of rotation.By the screens of collar 11 and complete machine bracket fixing plate 12 is set, can realize that bearing pin 15 and complete machine bracket fixing plate 12 are synchronous.By the relative screens scope of complete machine bracket fixing plate 12 and base support fixed plate 13 is set, can realize that the rotating shaft slewing area regulates.The structure of body cradle 14 is convenient to the socket with zero motor output shaft 4, makes when assembling exists output shaft 4 axial angle deviations, output shaft transversal discrepancy, still can keep the output of zero motor 3 and the flexible socket of revolute pair 1, transmits moment of rotation.When base does not need rotating function, only need this rotating assembly is replaced to common fixed base support part, when fixed hole position, just can realize the compatibility of two kinds of functional modes fully.

It is pointed out that the preferred embodiment of the present utility model that just illustrates recited above.Some variations, improvement, interpolation or replacement that all various equivalent modifications are made on the utility model principle basis also should belong to and fall into protection domain of the present utility model.
