[0003] Encoders are often used in motors, see Figure 1 , is a motor in the related art. For the convenience of describing the motor 5, the end where the motor shaft is located is named as the head end 51, and the end of the motor 5 away from the output shaft is named as the tail end 52. The tail end 52 of the motor 5 is provided with a protective mesh plate 53, and a connecting hole is opened on the protective mesh plate 53. The encoder is fixed to the protective mesh plate 53 through a bracket, and the encoder is connected to the output shaft of the motor 5 through the connecting hole.

[0005] In order to improve the problem in the related art that the encoder is inconvenient to install on the motor, the present application provides an encoder installation structure.

[0006] The present application provides an encoder installation structure, which adopts the following technical solution:

[0024] By adopting the above technical solution, the position of the slot on the limiting member can be changed by sliding the connecting seat, so that the fixing mechanism can adapt to screens with various apertures.

[0025] Optionally, the adjusting member is a screw rod, the adjusting member is rotatably connected to the limiting member, the adjusting member passes through the connecting seat, and the adjusting member is threadedly connected to the connecting seat.

[0045] The following is combined with Figure 2-4 This application is described in further detail.

[0046] The present application embodiment discloses an encoder installation structure. Figure 1 and Figure 2 The mounting structure includes an encoder body 1 and a plurality of fixing mechanisms 2, wherein the fixing mechanisms 2 are used to fix the encoder body 1 to the tail of the motor 5, and the number of the fixing mechanisms 2 is determined by the actual working conditions. In this embodiment, two fixing mechanisms 2 are provided as an example for description.

[0047] Reference Figure 3 The fixing mechanism 2 includes a threaded member 21 and a plurality of limiting members 22 .

[0048] The threaded member 21 includes a limiting portion 211 and a threaded portion 212 . The threaded portion 212 is vertically fixed to one side of the limiting portion 211 .

[0049] The number of the limiting members 22 is determined according to actual needs, and the limiting members 22 may be one, two, or three, etc. In this embodiment, the example in which the limiting members 22 are two is used for description.

[0050] The two limiting members 22 are both arranged on the side of the limiting portion 211 where the threaded portion 212 is located, and the two limiting members 22 are symmetrically arranged about the threaded portion 212. One end of the limiting member 22 is hinged to the limiting portion 211, and the other end of the limiting member 22 extends out of the limiting portion 211.

[0051] The encoder body 1 is provided with a plurality of through holes for passing the threaded portions 212 .

[0052] In the process of installing the encoder body 1 to the motor 5, firstly, the limiting part 211 of the fixing mechanism 2 is passed through the mesh at the rear of the motor 5 and then extended into the motor 5. In this process, the limiting member 22 can be rotated in the direction of the threaded part 212, so that the limiting part 211 and the limiting member 22 can be smoothly extended into the motor 5 together, and then the limiting member 22 is rotated to rotate away from the threaded part 212 until it abuts against the limiting part 211, and then the fixing mechanism 2 is pulled to make the two limiting members 22 abut against the mesh plate 53 at the rear of the motor 5, and then the threaded part 212 of the fixing mechanism 2 can be passed through the through hole on the encoder and fixed with the nut 23. The operation is simple and convenient.

[0053] In order to reduce the space occupied by the limiting member 22, a plurality of mounting grooves 2111 are opened on one side of the limiting portion 211 facing the threaded portion 212. The plurality of mounting grooves 2111 correspond to the plurality of limiting members 22 one by one. The mounting grooves 2111 extend to the side wall of the limiting portion 211, and the limiting member 22 is hinged into the mounting grooves 2111.

[0054] An elastic member 24 is arranged between the limiting member 22 and the limiting portion 211 . The elastic member 24 may be a spring or a torsion spring, etc. In this embodiment, the elastic member 24 is described using a torsion spring as an example. The elastic member 24 is arranged at the hinge axis between the limiting member 22 and the limiting portion 211 .

[0055] Under the action of the elastic member 24, the limiting member 22 is coplanar with the limiting portion 211. Thus, when the worker pushes the limiting portion 211 and the limiting member 22 of the fixing mechanism 2 into the mesh at the tail of the motor 5, the limiting member 22 is reset under the action of the elastic member 24, and it is no longer necessary to manually move the limiting member 22, thereby making the installation process of the fixing mechanism 2 more convenient.

[0056] The limiter 22 is provided with a slot 2221. After the limiter 211 and the limiter 22 are inserted into the motor 5 through the mesh, the limiter 22 is reset under the action of the torsion spring, and the slot 2221 of the limiter 22 is connected to the mesh plate 53 at the tail of the motor 5, and then the encoder body 1 is fixed by the fixing mechanism 2, so that the fixing mechanism 2 has a better fixing effect on the encoder body 1.

[0057] The limiting member 22 includes a main body 221 and a connecting seat 222. The main body 221 is provided with a slideway 2211 arranged axially along the main body 221. The connecting seat 222 is slidably connected to the slideway 2211. Under the restriction of the slideway 2211, the connecting seat 222 can only slide axially along the slideway 2211. The slot 2221 is set on the connecting seat 222.

[0058] The position of the slot 2221 can be adjusted by adjusting the position of the connecting seat 222 in the slideway 2211 , so that the fixing mechanism 2 can adapt to the mesh plates 53 with various apertures.

[0059] Reference Figure 3 In order to save the space occupied by the slideway 2211 on the limiting member 22, the slideway 2211 is configured as a groove body opened to the limiting member 22, and the cross section of the slideway 2211 is dovetail-shaped.

[0060] The limiting mechanism further includes an adjusting member 25, which is used to change the position of the connecting seat 222 in the slideway 2211 and to limit the position state of the connecting seat 222 after adjustment.

[0061] The adjusting member 25 is a screw rod, which is arranged in the slideway 2211 along the axial direction of the slideway 2211 and passes through the connecting seat 222. The adjusting member 25 and the connecting seat 222 are arranged to be threadedly connected, and one end of the adjusting member 25 is rotatably connected to the inner wall of the slideway 2211.

[0062] The connecting seat 222 can be moved in the slideway 2211 by screwing the adjusting member 25 , and after the position state of the connecting seat 222 is adjusted, the adjusting member 25 can also limit the position state of the connecting seat 222 .

[0063] In order to facilitate the screwing of the adjusting member 25 , a hexagram groove 251 is formed at the end of the adjusting member 25 .

[0064] Both sides of the slot 2221 on the connection seat 222 are provided with elastic clamping plates 26, which are arranged along the axial direction of the slot 2221. The slot 2221 is an arc-shaped slot, and the clamping plate 26 is an arc-shaped plate, and the arc of the clamping plate 26 is the same as that of the slot 2221, and the inner side of the clamping plate 26 faces the side where the slot 2221 is located. A clamping area 3 is formed between the two clamping plates 26 and the slot 2221.

[0065] After people pass the limiting portion 211 and the limiting member 22 of the fixing mechanism 2 through the mesh plate 53 at the tail of the motor 5, the mesh plate 53 is temporarily clamped together with the limiting member 22 through the clamping area 3. At this time, it is no longer necessary to manually fix the fixing mechanism 2, which is convenient for subsequent operations.

[0066] In order to facilitate people to screw the nut 23, a plurality of toggle rods 4 are provided on the side wall of the nut 23. One end of the toggle rod 4 is hinged to the side wall of the nut 23, and an elastic member 41 is provided between the toggle rod 4 and the nut 23. Under the action of the elastic member 41, the toggle rod 4 is parallel to and close to the side wall of the nut 23, so as to reduce the space occupied by the toggle rod 4.

[0067] In addition, a plurality of arrangement grooves 231 are provided on the side wall of the nut 23, and the plurality of arrangement grooves 231 correspond one to one with the plurality of toggle rods 4. The toggle rods 4 are arranged in the installation grooves 2111. This can further reduce the space occupied by the screw rods.

[0068] In order to facilitate people to rotate the toggle rod 4, the arrangement groove 231 extends to the end surface of the nut 23. One end of the toggle rod 4 extends out of the arrangement groove 231.

[0069] The implementation principle of an encoder installation structure of an embodiment of the present application is as follows: a plurality of fixing mechanisms 2 are installed to the mesh plate 53 at the tail of the motor 5. During the installation process, first, the limiting portion 211 of the fixing mechanism 2 and a plurality of limiting members 22 are extended through the mesh hole into the motor 5, and the limiting member 22 is reset under the action of the elastic member 24, and then the mesh plate 53 is clamped together with the clamping area 3 on the limiting member 22, so that the fixing mechanism 2 is temporarily fixed to the mesh plate 53, and then the threaded portions 212 of the plurality of fixing mechanisms 2 are sequentially passed through the through holes on the encoder body 1, the nut 23 is screwed to the threaded portion 212, and the nut 23 is continuously screwed by the toggle rod 4 so that the nut 23 is pressed tightly against the encoder body 1.

[0070] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
