Description

Vibrator for incoming signal of mobile communication terminal {A vibrator for recieving signal of personal digital assistant}

The present invention relates to a vibration device for an incoming signal of a mobile communication terminal. In particular, it is possible to fix the stator in the vibrator easily without damage without using any adhesive, and to more securely fix the stator, and to simplify the structure and manufacturing process by not increasing the number of parts of the vibrator. The present invention relates to a vibration device for an incoming signal of a mobile communication terminal.

In general, the electronic device has a built-in various types of signal generators for allowing the user to recognize the operating state set according to the intended use by hearing or tactile sense. The signal generator includes an alarm device for a table clock or a wall clock to indicate that the set time is reached. In addition, in recent years, subscribers can carry with their mobile phones anytime, anywhere to communicate with the desired party, and news, securities, transportation, sports, travel information, such as electronic devices that can receive a variety of life information, such as voice as well as text There is an incoming signal generator of the mobile communication terminal.

Among these, the mobile communication terminal generates an incoming call regardless of time and place, and many people are surprised or frowned. What is developed to solve the disadvantage of the mobile communication terminal is a vibration device for the incoming signal of the mobile communication terminal. The vibrator is equipped with a small cylindrical vibration motor in a portable pager and mobile telephone, and an unbalanced weight is mounted on the rotating shaft of the vibration motor so that the vibration effect is generated by motor rotation upon reception.

One of the vibration signals for the incoming signal of the conventional mobile communication terminal is shown in the accompanying drawings, FIGS. 1A to 2.

As shown in FIG. 1A, the vibration signal for the incoming signal of the conventional mobile communication terminal is mainly composed of a cylindrical vibration motor and an unbalanced weight. The vibration motor is a cylindrical case 110, a stator 120, a stator, a rotating shaft 140, a rotor 160, a rotor, a segment 170, a segment, a molding base 180, a molding base 192, and a lead wire 192. Brush 190, the bearing 142, the elastic packing member 144 and the like connected to.

The cylindrical case 110 is a cylindrical container shape in which one end surface is opened and the other end surface is a closed bottom portion 116 formed therein, and a hollow shaft in which a longitudinal shaft hole 118 is drilled in the inner center of the bottom portion 116. A tubular mounting protrusion 114 is formed, and has a predetermined inner space to the outside, and forms a structure in which an outer wall 112 is formed. The cylindrical stator 120 is inserted into and mounted in the mounting protrusion 114 of the cylindrical case 110, and the rotating shaft 140 is mounted in the shaft hole 118 and the bearing 142 at both ends of the shaft hole 118. Supported. Outwardly there is a cylindrical rotor 160 and a segment 170 consisting of three segments. Two segments 190 of the segment 170 are contacted and connected to each other and then connected to an external power source through the lead wire 192. The other open end surface of the cylindrical case 110 is sealed with a molding base 180 while allowing the lead wire 192 to be drawn out. The unbalanced weight 150 is mounted at the other end of the rotating shaft 140 protruding outward from the bottom 116 of the cylindrical case.

The vibration signal for the incoming signal of the mobile communication terminal having such a structure is applied to the rotor 160 made of a winding after the power is transmitted to the segment 170 through the lead wire 192 and the brush 190 when power is applied from the outside. In addition, the weight 150 rotates together with the rotation shaft 140 by the change of the electromagnetic field generated between the stator 120 and the rotor 160 to cause the electronic device to vibrate.

However, the conventional apparatus for receiving signals vibrating in the mobile communication terminal has some problems in mounting the stator 120 to the mounting protrusion 114 formed inside the bottom surface 116 of the cylindrical case.

Looking at this in detail through the accompanying drawings in Figure 1b, the conventional cylindrical vibration motor of the vibrating device vertically mounted mounting 114 is a shaft hole 118 inside the bottom portion 116 of the cylindrical case 110 to form an outer shell And the cylindrical stator 120 is inserted and mounted on the outer circumference of the mounting protrusion 114. At this time, the cylindrical stator 120 inserted between the two through the appropriate adhesive 130 between the outer peripheral surface of the mounting protrusion 114 and the inner peripheral surface of the stator 120 in order to be securely fixed on the mounting protrusion 114. Was fixed tightly.

However, in the assembly process of mounting the stator 120 to the mounting protrusion 114 as described above, the rotating shaft is mounted on the mounting protrusion 114 before the adhesive 130 interposed between the mounting protrusion 114 and the stator 120 dries. The flow of the 140 or the rotor 160 to the place where the other parts are unnecessarily bonded, fixed, or accumulated in the inner space of the cylindrical case 110 and hardened to fill the space, such as the rotor 160 There was a problem such as preventing it from rotating.

In addition, this vibrating device is usually small in size because the inner space of the cylindrical case 110 is narrow, there is a disadvantage that the operator body to reach the adhesive 130 between the mounting projection 114 and the stator 120 is not easy.

On the other hand, in order to solve this disadvantage, conventionally, as shown in the accompanying drawings, Figure 2 has been developed a vibrating device is formed by separating the mounting projection of the cylindrical case 210 in the cylindrical case 210 itself. That is, the mounting protrusion 214 having the shaft hole 218 drilled inside the cylindrical case bottom portion 216 is formed to protrude from the bottom portion 216 at a very low height, and at the center thereof, the shaft protrusion such as the mounting protrusion 214 is formed. There is a 222 and one end of the shaft hole (222) to form a stator mounting tube 220 in which the inner circumferential groove 224 corresponding to the outer diameter of the mounting projection 214 is formed separately to mount the outside of the cylindrical case 210. After the stator 230 is bonded on the outer circumference of the tube 220 using a suitable adhesive 240, the vibrating device is installed so as to be inserted into the mounting protrusion 214 in the cylindrical case 210 integrally. will be. At this time, the mounting tube 220 was formed in the inner circumferential groove 224 formed at one end of the shaft hole 222 to an appropriate size to be fitted on the mounting protrusion 214, or to be fixed using an adhesive.

However, when the mounting tube 220 for mounting the stator 230 is provided separately, the number of parts of the vibrator increases and the structure becomes complicated, and mold manufacturing fixing and manufacturing costs for manufacturing the mounting tube 220 are added. Of course, another problem that the assembly process for installing the stator 230 in the cylindrical case 210 is complicated.

The purpose of the present invention to solve the above problems is to mount the stator to the vibration vibration device for the incoming signal vibration device of the mobile communication terminal in the vibration motor without the need to use a separate adhesive stably without damage The present invention provides a vibrating device for an incoming signal of a mobile communication terminal that can be securely fixed and suppresses an increase in the number of parts of the vibrating device to simplify the overall structure and assembly process.

In the center of the mounting protrusion 316 is formed a shaft hole 318 penetrating along the longitudinal direction to the outside of the bottom surface portion 314. In particular, the mounting protrusion 316 is formed such that the length from the bottom portion 314 to the inner end surface of the cylindrical case 310 is sufficiently longer than the length of the cylindrical stator 330, the stator 330 is mounted Afterwards, the protrusion 317 of the mounting protrusion 316 protruding out of the end surface thereof has a length corresponding to the thickness of the stator 330. In addition, a stator seating portion 315 is formed around the bottom of the mounting protrusion 316 that meets the cylindrical case bottom portion 314. The stator seat 315 is formed in a shape in which the inner diameter of the shaft hole 318 is extended outside the bottom of the cylindrical case bottom portion 314 and pressed in a predetermined depth into the case.

Inserting the cylindrical stator 330 on the outer circumference of the mounting protrusion 316, the end surface of the stator 330 side of the bottom portion 314 side of the cylindrical case 310 is in contact with the stator seat 315, A part of the end of the mounting protrusion 316 is partially protruded out of the opposite end surface of the stator 330. At this time, one ring-shaped elastic packing member 344 having a predetermined elastic force is inserted between the stator seat 315 and the end face of the stator 330 in contact with the stator seat 315, and the opposite end face of the stator 330 is the same. Two ring-shaped elastic packing member 344 is inserted. Then, the protrusion 317 of the mounting protrusion 316 protruding out of the end surface of the stator 330 becomes a bent portion that is bent radially outward with respect to the shaft hole 318 to the corresponding end surface of the stator 330.

In this way, the stator 330 is inserted and mounted on the outer circumference of the mounting protrusion 316, and then the stator seating portion of the mounting protrusion 316 formed at one end thereof on the bottom 314 side of the cylindrical case 310. The other end surface is pressed and supported by the bent protrusion 317 of the mounting protrusion 316 while being firmly fixed to the support 315.

The accompanying drawings, Figure 4 shows another embodiment of the vibration signal for the incoming signal of the mobile communication terminal implemented according to the present invention.

As shown in this figure, the vibration device of the present embodiment implements the basic shape of the cylindrical case 410 forming the shell of the vibration motor in the same manner as in the first embodiment. However, in the present embodiment, unlike the first embodiment, after inserting the cylindrical stator 430 on the outer circumference of the mounting protrusion 416, the mounting protrusion protrusion protruding outward through the inner diameter of the stator 430 ( The outer periphery 419 is formed around the outer periphery of the mounting protrusion 416 by partially extending the shaft hole 418 radially outward with respect to the center line, and the outer periphery 419 is the elastic packing member 444. The stator 430 is firmly fixed on the mounting protrusion 416 by contacting the end surface of the stator 430 and pressing and supporting the stator 430 in the longitudinal direction.

The cylindrical case 410 and the stator 430 coupled as described above are used after being combined with other components in the same process as in the aforementioned vibration signal for the incoming signal of the conventional mobile communication terminal. Therefore, the following description of the bonding process and operation will be omitted.

The vibration signal for the incoming signal of the mobile communication terminal of the present invention implemented in the first and second embodiments is a cylindrical shape on the outer circumference of the mounting protrusion without using any adhesive in mounting the stator to the cylindrical case forming the outer shell of the vibration motor. After inserting the stator, the protrusion of the mounting protrusion protruding out of the stator end simply bends radially outward or its shaft hole extends outward to contact the end face of the stator and press the stator in the longitudinal direction so that the stator flows on the mounting protrusion. It can be secured without

In addition, the second embodiment of the prior art includes a separate mounting tube for installing the stator increases the number of parts of the vibration device and the structure is complicated, as well as the assembly process is complicated, the mobile communication terminal of the present invention The incoming signal vibrator can be easily and quickly mounted and fixed to the mounting protrusion formed integrally in the cylindrical case without such a separate mounting tube, thereby suppressing the increase in the number of parts of the vibrator and its assembly process and being relatively simple. Keep the existing structure.

In addition, each of the elastic packing member inserted into both ends of the stator absorbs the shock that can be applied to both ends of the stator during the mounting or operation of the stator on the mounting projection so as not to burn out the stator, formed on the bottom of the mounting projection The stator seating jaw can prevent the stator from being burned out by absorbing the shock that can be applied in the assembling process in which the mounting protrusion protrusion is bent or extended after the stator is inserted again. Make sure

As described above, the vibration signal for the incoming signal of the mobile communication terminal implemented by the present invention enables the stator to be more easily and easily mounted without being burned inside the cylindrical vibration motor without using a separate adhesive, and thus more securely fixed. In addition, there is an advantage to prevent the increase of parts of the vibration device to simplify the overall structure and assembly process.
