At present, a micro-servo is an engine that controls mechanical elements to operate in a servo system, and is an indirect speed change device of a supplementary motor. The micro-servo can control the speed and position accuracy very accurately, and can convert the voltage signal into torque and rotating speed to drive a control object. The rotation speed of the rotor of the micro-servo is controlled by the input signal and can quickly respond, the micro-servo is used as an actuating element in an automatic control system, has the characteristics of small electromechanical time constant, high linearity, starting voltage and the like, and can convert the received electric signal into angular displacement or angular speed on a motor shaft for output. The servo motor is divided into two categories of direct current servo motors and alternating current servo motors, and is mainly characterized in that when the signal voltage is zero, the signal voltage has no autorotation phenomenon, and the rotating speed is reduced at a constant speed along with the increase of the torque. Up to now, most of high-performance electric servo systems adopt permanent magnet synchronous alternating current servo motors, and most of control drivers adopt all-digital position servo systems with rapid and accurate positioning. Typical manufacturers are e.g. Siemens Germany, Kolmogong and Japan Songhua and Anchuan.

In order to achieve high dynamic water resistance, a general design of the existing micro-server is that a waterproof rubber ring is in interference fit with an output shaft, and the inner side of the waterproof rubber ring is completely in fit contact with the output shaft, so that high-level dynamic water resistance is guaranteed.

Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
It should be noted that, for the existing micro server, since the micro server is an electronic device, and the micro server needs to be connected to a power input voltage for operation, the waterproof level of the micro server needs to be a certain level, so as to prevent external water drops and other conductive media from entering the micro server to cause short circuit. The micro server is mainly divided into two layers, wherein one layer is static waterproof, namely the waterproof between the shell and the shell is static waterproof; the other layer is dynamic waterproof, namely the waterproof between the shell and the output shaft is dynamic waterproof. The existing miniature server is waterproof statically or dynamically, and the waterproof work of the miniature server is mainly finished by the rubber material. For static waterproofing, the static waterproofing can easily reach a high waterproofing level because the shell and the shell do not move relatively, i.e. the waterproof rubber ring arranged between the shell and the shell is generally not damaged; and for the waterproof dynamic, the waterproof dynamic is difficult to reach high waterproof level, because the output shaft can rotate relatively to the casing, the output shaft rotates and just means and takes place sliding friction with waterproof rubber ring and produce the heat, and the heat can transmit to waterproof rubber ring on, leads to waterproof rubber ring to take place wearing and tearing.
However, in the conventional micro-server, in order to achieve high level of dynamic water resistance, the general design is to make the waterproof rubber ring and the output shaft press against each other in an interference manner, and make the inner side of the waterproof rubber ring completely contact with the output shaft in a fitting manner, so as to ensure high level of dynamic water resistance. Although the design can improve the waterproof grade to a certain extent, a plurality of problems can be brought at the same time, firstly, the inner side of the waterproof rubber ring is completely attached and contacted with the output shaft, namely, the friction force between the waterproof rubber ring and the output shaft is large, the generated heat is very large when the output shaft rotates, once the heat is too high, the waterproof rubber ring can be damaged by the too high heat, namely, the aging of the waterproof rubber ring is accelerated, and the waterproof rubber ring made of general rubber materials can be aged more quickly under the condition of high heat, so that the service life of the waterproof rubber ring is greatly reduced; secondly, if the waterproof rubber ring is easily damaged due to too high heat, the miniature server needs to be maintained in a later period by spending larger time and energy, and the service condition of the waterproof rubber ring in the miniature server needs to be closely concerned to prevent the waterproof rubber ring from being damaged; thirdly, because the friction between the waterproof rubber ring and the output shaft is large, when the output shaft rotates, the rotation speed of the output shaft can be greatly reduced, and the power of the miniature server is greatly reduced.
Therefore, based on the above problem, the present application discloses a waterproof rubber ring and a micro-server, a waterproof performance is strong, can not take place too big physical contact with output, longer and not fragile waterproof rubber ring and micro-server of life.

Specifically, the radial ring body group 22 includes 2 to 4 half-arc ring bodies 22 a. In this way, it should be noted that the specific number of the half-arc ring bodies 22a can be flexibly set according to actual conditions, but it is not desirable to design too many, otherwise, on one hand, the manufacturing difficulty of the waterproof rubber ring 20 is increased, and on the other hand, the friction force between the miniature servo and the rubber ring is too large, and the preferable number is 2 to 4.
Referring to fig. 1, the axial ring 23 is disposed on the annular frame 21.
