Description

Technical Field

[0001] The utility model relates to the technical field of robot steering wheels, in particular to an installation structure of a steering wheel encoder and a steering wheel. Background Art

[0002] With the development of intelligent technology, it is usually necessary to use an encoder to read the steering angle and driving speed of the steering wheel during the control of the steering wheel. Figure 1 As shown, there are three wire outlets 11 at the steering wheel motor 1, which results in a small space at the output end of the motor 1 and crowded wire outlet positions. Conventional encoder installation methods cannot achieve the connection between the encoder and the motor output shaft. Therefore, a steering wheel encoder installation structure is needed to improve these problems. Utility Model Content

[0003] In response to the above problems, the utility model provides a steering wheel encoder installation structure and a steering wheel, which can read steering wheel related data without going through the steering wheel wire outlet, solving the problems of narrow space and crowded wire outlet position at the steering wheel wire outlet.

[0004] Specifically, the utility model is achieved as follows:

[0005] A mounting structure for a steering wheel encoder, wherein the encoder is mounted on a motor via a mounting bracket and the encoder is connected to the motor shaft via a transmission assembly;

[0006] The mounting bracket is arranged at the non-driving end of the motor and is connected to the non-driving end of the motor shaft through the transmission assembly;

[0007] The transmission assembly comprises:

[0008] a first pulley fixedly connected to the non-driving end of the motor shaft;

[0009] The second pulley is arranged below the mounting bracket and is connected to the rotating shaft of the encoder for driving the rotating shaft of the encoder to rotate synchronously. The first pulley and the second pulley are connected by a synchronous belt.

[0010] Furthermore, a rotating shaft is connected to the rotating shaft of the encoder, which passes through the mounting bracket and is coaxially mounted with the second pulley and is connected by a key. Two bearings are fixed on the rotating shaft, and the second pulley is located between the two bearings.

[0011] Furthermore, the rotating shaft is connected to the rotating shaft of the encoder via a top screw.

[0012] Furthermore, a support member is provided at the bottom of the encoder, and two ends of the support member are respectively connected to the encoder and the mounting bracket to mount the encoder on the mounting bracket.

[0013] Furthermore, the support member is a vertically arranged S-shaped bent support spring, the upper end of which is connected to the encoder, and the lower end is connected to the mounting bracket.

[0014] Furthermore, the first pulley is connected to the non-driving end of the motor shaft via a key.

[0015] Furthermore, the mounting bracket is in a "π" shape and is fixedly connected to the non-driving end of the motor by screws.

[0016] A steering wheel comprises a motor, a connector and a running wheel. A plurality of cable outlets for routing cables are provided at the connection between the motor and the connector. The steering wheel encoder also comprises the mounting structure as described above.

[0017] Compared with the prior art, the working principle and beneficial effects of this utility model are as follows:

[0018] (1) The installation structure of the steering wheel encoder provided by the utility model is such that when the motor shaft rotates, it drives the first pulley on its non-driving end to rotate, and then drives the second pulley to rotate through the synchronous belt. The second pulley drives the rotating shaft and the rotating shaft of the encoder to connect, so that the encoder reads the value of the motor shaft, thereby leaving space for the wiring of the steering wheel outlet, solving the problem of narrow space at the steering wheel outlet and crowded outlet position.

[0019] (2) The support member adopts an S-shaped bending support spring, which serves as a support to support the rotating shaft of the encoder and separate it from the plane of the mounting bracket. At the same time, it can produce slight deformation to avoid the problem of being unable to install due to errors in the position of the connecting screw holes, thereby improving adaptability.

DETAILED DESCRIPTION

[0028] The present invention will be further described in detail below through specific implementations in conjunction with the accompanying drawings.

[0029] Example 1

[0030] like Figure 2 As shown, this embodiment discloses a steering wheel, including a motor 1, a connector 2, a running wheel 3 and an encoder 41. The running wheel 3 is driven by the motor 1. The encoder 41 is installed in the rear end cover 12 of the motor 1 through the encoder mounting structure 4 to obtain the rotational speed of the motor 1. The output end of the motor 1 is the front cover. The front cover is provided with three wire outlets 11 for routing. The motor shaft 13 of the motor 1 is divided into a driving end and a non-driving end. The non-driving end is located behind the rear end cover 12. The driving end drives the running wheel 3 to move through a gear pair and other transmission components. The specific structure is a conventional structure of a vertical steering wheel and will not be described here.

[0031] like Figure 2-5 As shown, the mounting structure of the encoder includes: an encoder 41, a mounting bracket 43 and a transmission assembly. The "π"-shaped mounting bracket 43 is fixedly connected to the non-driving end of the motor 1 by screws, and the encoder 41 is fixed on the mounting bracket 43 by an S-shaped supporting spring 44, with its rotating shaft 411 facing downward. The supporting spring 44 props up the encoder 41, so that the encoder 41 body and its rotating shaft 411 are separated from the mounting bracket 43. At the same time, the supporting spring 44 can produce slight deformation and can be adjusted in a small range of position, so that the screw hole on it is aligned with the mounting screw hole on the mounting bracket 43, avoiding the problem of installation failure due to errors in the position of the screw holes, thereby improving adaptability.

[0032] The transmission assembly includes: a first pulley 421, a second pulley 422, and a synchronous belt 423. The first pulley 421 is connected to the non-drive end of the motor shaft 13 via a key 5. The second pulley 422 is located below the mounting bracket 43 and is connected to the rotating shaft 411 of the encoder 41 via a rotating shaft 6 to drive the rotating shaft 411 to rotate synchronously. The rotating shaft 6 passes through the mounting bracket 43 and the second pulley 422 from top to bottom. The rotating shaft 6 is connected to the second pulley 422 via a key 5. Bearings 8 are provided on both the upper and lower sides of the second pulley 422. The rotating shaft 6 is fixedly connected to the inner ring of the bearing 8. The second pulley 422 is located between the two bearings 8 and is axially limited by the two bearings 8. The top of the rotating shaft 6 is fixedly connected to the rotating shaft 411 of the encoder 41 via a set screw 7 (fastening screw).

Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
