Description

Antenna driving device {Driving apparatus for an antenna}

The present invention relates to an antenna driving apparatus, and more particularly, to an antenna driving apparatus suitable for pulling in / out an antenna mounted in a small apparatus such as a mobile communication terminal.

Generally, mobile communication terminals such as cellular phones, personal communication systems (PCS), personal digital assistants (PDAs), international mobile telecommunications (IMT-2000), and the like are generally used. A rod antenna (hereinafter referred to as an 'antenna') is provided. In consideration of the call quality and the efficient use of the battery, it is preferable to use the antennas by pulling the antennas out of the housing when the devices are in operation and bringing the antennas back into the housing after the call. In order to provide the convenience of antenna withdrawal / retraction, the present inventor has proposed a driving device that automatically enables antenna withdrawal / retraction (see Korean Patent No. 288,128 and its corresponding US Pat. No. 6,163,682). ).

However, according to the recent trend, mobile communication terminals are not only smaller in size, but also increasingly diverse in design in order to satisfy various types of consumer needs. As the size of the terminal is reduced, the installation space of the antenna driver is reduced and the type of antenna is diversified according to the diversification of the terminal design, which makes the installation conditions of the antenna and the antenna driver difficult.

In a conventional antenna drive device, the force for pulling out / retracting an antenna utilizes a friction force between a rotating roller and an antenna orthogonally circumscribed thereto. As a configuration for this, for example, a method of arranging the antennas orthogonally between two rollers arranged side by side (the prior patent according to this method), or a method of arranging the antennas orthogonal to the rollers between one roller and the guide member And the like can be considered. Further, the roller is connected to the output shaft of the geared motor incorporating the motor and the reduction gear assembly coupled thereto or the two elements so as to rotate in a forward or reverse direction.

According to this configuration, the antenna orthogonally circumscribed to the roller is forced by linear motion by the frictional force with the rotating roller to take out / retract (ie, drive). In this case, in order to ensure smooth driving of the antenna, an appropriate contact pressure between the antenna and the roller should be secured. However, the conventional antenna drive device has a structure in which the roller is fixed to the output shaft of the gear assembly or the geared motor so that the flow of the rotational axis thereof is impossible. In addition, if the design of the terminal is changed, the installation position of the antenna driving device is changed or the diameter of the antenna is changed. For these reasons, in order to obtain an appropriate contact pressure between the roller of the antenna driving device and the antenna, an antenna driving device designed for the diameter of the antenna and the design of the mobile communication terminal is required. This limitation of the scope of application of one model consequently requires the rapid development and replacement cycle of the model of the antenna drive, resulting in an increase in production cost. In addition, even in the terminal of the same design, if the diameter of the antenna, the diameter of the roller, the roundness, the installation position of the antenna driving device, etc. are not correct, the contact pressure between the roller of the driving device and the antenna is too large or too small to drive the antenna. There is a high possibility of product defects because it is not smooth.

SUMMARY OF THE INVENTION An object of the present invention is to apply an antenna driving device having a structure that can be widely applied to mobile communication terminals of various designs, in particular, antennas of various diameters, to provide a suitable contact pressure between the antenna and the roller, and to reduce product defects caused by the antenna driving.

1 is a perspective view of an antenna driving apparatus according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of the antenna driving apparatus of FIG. 1, and FIG. 3 is a line II along the antenna coupled to the antenna driving apparatus of FIG. 1. It is a partial cross section.

1 to 3, the antenna driving apparatus 100 according to the present invention is installed in a mobile communication terminal for conveniently drawing or drawing an antenna, and the rotating driving means 110 having a rotating shaft 112 is provided. Equipped. It is preferable to use the geared motor (110a) as the rotation drive means (110). The geared motor 110a is composed of a motor unit 111 and a gear assembly 116 for deceleration. The gear assembly 116 is rotated by a ring gear 116a fixedly installed on the motor unit 111, a planetary gear 116b that rotates while being rotated while being inscribed in rotation with the ring gear 116a, and a planetary gear 116b that revolves. And a sun gear 116d for rotating the planetary gear 116b. Since the driving speed of the motor is reduced by using a ring gear, a planetary gear, a sun gear, a carrier, and the like, a detailed description of the gear assembly 116 will be omitted. In addition, the dashed-dotted line in FIG. 3 represents a state in which a connector for power supply is installed.

In addition, as shown in Figs. 1 to 3, it is preferable to directly use a geared motor 110a as the rotation driving means 110 in the present invention. Means may be used. For example, a driving device for driving the cover of the mobile communication terminal may be jointly used as the rotation driving means (110).

As shown in FIG. 2 and FIG. 3, the groove 113 is formed in the bottom part of the rotating shaft 112 along the circumferential surface, and the rotating shaft of the bottom part is gathered. This groove 113, ie the angular rotary shaft bottom, allows the inclined allowable coupling means 120 described later to be engaged.

Antenna drive device 100 according to the present invention is provided with a rotary contact means (130). The rotation contact means 130 is for pulling in or drawing out the antenna 10 while being rotated by the power of the rotation driving means 110 in a state in which one side thereof is in contact with the antenna 10. The rotary contact means 130 is preferably disposed to be substantially orthogonal to the antenna 10, the outer surface of which is in contact with the outer surface of the antenna 10. Of course, the rotary contact means 130 is not necessarily arranged to be orthogonal to the antenna 10. The rotary contact means 130 is installed to be inclined at a predetermined angle with respect to the rotary shaft 112 by an external force, and in an inclined state, the rotary contact means 130 receives a force to be restored to its original position by the elastic force providing means 140 such as a coil spring. .

The rotary contact means 130 is provided with a coil spring receiving portion 132 for receiving one end of the coil spring 140a. The coil spring receiving portion 132 is formed in a container shape surrounded by the bottom and sidewalls so that the upper end of the coil spring 140a is not separated.

The outer circumferential surface of the coil spring receiving portion 132 is formed so that the protrusion 133 protrudes outward. It is preferable that three projections 133 are provided at 120 ° intervals, but in some cases, two projections 133 may be provided at 180 ° intervals. Of course, four or more protrusions 133 may be provided at different angular intervals. This protrusion 133 is a portion coupled to the inclined allowable portion 122 of the inclined allowable coupling means 120 to be described later.

The rotary contact unit 130 includes a roller shaft 134 extending integrally from the center of the coil spring receiving portion 132 and having a length longer than that of the antenna 10. The longitudinal direction of the roller shaft 134 is substantially orthogonal to the longitudinal direction of the antenna 10. An end stop 135 is formed at the end of the roller shaft 134 along its outer circumferential surface, and an elastic roller 136 in contact with the antenna 10 is disposed inside the end stop 135 of the roller shaft 134. Combined. In this case, the roller shaft 134 may be configured as a long sphere. Since the elastic roller 136 is introduced as a medium for providing a sufficient contact pressure between the rotary contact means 130 and the antenna 10, when the roller shaft 134 is made of a material having a large friction force against the antenna 10 The elastic roller 136 can also be configured without installation.

Between the rotation driving means 110 and the rotary contact means 130, the allowable inclined coupling means 120 is installed. The tilt allowable coupling means 120 transmits the rotational power of the rotation driving means 110 to the rotation contact means 130 so that the rotation contact means 130 can be rotated, and the rotation contact means 130 is Allow to tilt relative to the axis of rotation 112. The inclined allowable coupling means 120 has a container shape having a bottom 121 and a side wall 126. The side wall 126 and the bottom of the allowable slope coupling means 120 can be coupled to the rotation shaft 112 through the groove 113 formed on the rotation shaft 112. A cutout portion 124 is formed by cutting a portion of the 121. The cutting groove 124 extends to the center of the bottom 121, and the end of the cutting groove 124 at the center of the bottom 121 is tightly coupled with the groove 113 so as not to be released from the rotation shaft 112 and to receive the rotational force. Make it look as possible. In addition, the side wall 126 allows the rotation contact means 130 to be coupled, and inclined allowable portion allowing the rotation contact means 130 to be inclined in any direction with respect to the rotation shaft 112 in the coupled state ( Three 122 are formed at intervals of 120 degrees. In some cases, two inclined allowable portions 122 may be formed at 180 ° intervals or four or more at different angular intervals. The inclined allowable portion 122 is a portion to which the protrusion 133 of the rotary contact means 130 described above is coupled, and is formed larger than the protrusion 133 so that the protrusion 133 may be flowed in a coupled state, The inlet 122a of the protrusion 133 should be formed to be narrower than the protrusion 133 so as not to be separated. Of course, when the protrusion 133 can be forcibly coupled, the inlet 122a may be omitted.

A washer 150 is installed between the allowable tilt coupling means 120 and the rotation driving means 110, that is, the geared motor 110a. The washer 150 is to reduce the frictional force acting on the upper end of the geared motor (110a) and the allowable slope coupling means 120, it is not necessary. Of course, the inclined allowable coupling means 120 may be formed integrally with the rotation shaft 112 in some cases.

The connection method of the above-mentioned inclined allowable coupling means 120 and the rotary contact means 130 may be variously modified. For example, a protrusion may be formed in the inclined allowable coupling means 120, and an opening, such as the inclined allowable portion 122, may be formed in the rotary contact means 130 to be connected to each other. In some cases, instead of reducing the size of the inclined allowable coupling means 120, the coil spring accommodating part 132 of the rotary contact means 130 may be enlarged to accommodate the inclined allowable coupling means 120 therein. And the projections 133 may be formed inward so that the projections 133 may be coupled inward from the outside. As described above, the inclined allowable coupling means 120 and the rotation contact means 130 are interlocked to allow the rotational force transmission to each other through the male and female members, and the rotation contact means 130 is elastically inclined with respect to the rotation shaft 112. If so, various modifications of the structure or coupling of these two components 120 and 130 are possible.

Antenna driving device 100 according to the present invention is provided with an elastic force providing means 140. As the elastic force providing means 140 in this embodiment, the coil spring 140a installed between the inclined allowable coupling means 120 and the rotary contact means 130 is suitable. The elastic elasticity providing means 140, the diameter of the antenna 10 is larger than the standard size, when the rotary contact means 130 in contact with the antenna 10 is inclined at a predetermined angle with respect to the rotary shaft 112, the rotary contact means By pushing the 130 toward the antenna 10 serves to ensure a sufficient friction between the rotary contact means 130 and the antenna 10.

In addition, the coil spring 140a is not necessarily used as the elastic force providing means 140, and any one may be used as long as it can provide the elastic force to the rotary contact means 130. For example, the elastic force providing means 140 may be composed of two magnets disposed to face the same polarity between the rotary contact means 130 and the inclined allowable coupling means 120.

In this embodiment, the inclined allowable coupling means 120 and the elastic force providing means 140 allow the rotary contact means 130 to be rotated in an inclined state, and at the same time, the rotary contact means 130 moves the antenna 10. It provides an elastic force to pressurize, which will be referred to collectively as an elastic coupling means (170).

An antenna drive device according to the present invention includes an antenna support means 160. The antenna support means 160 supports the antenna 10 so that a friction force necessary for driving the antenna 10 can be generated between the antenna 10 and the rotary contact means 130. This antenna support means 160 is not necessary. For example, the antenna 10 may be made of a material having a very high rigidity to resist the bending force of the rotary contact means 130 without being bent, or the movement path thereof is narrowly limited when installed in a case of a mobile communication terminal. In the case of a separate antenna support means is not necessary.

The housing 160a is used as the antenna support means 160 in this embodiment. Housing 160a is also coupled to the motor (110a) serves to accommodate and protect the rotary contact means 130, inclined allowable coupling means 120, the elastic force providing means 140 described above. An antenna hole 162 through which the antenna 10 can pass and an end of the roller shaft 134 of the rotary contact means 130 are inserted into the housing 160a to form a guide hole 164 to be guided. The housing bracket 166 is coupled to the opening of the bottom long hole 164 of the housing 160a.

As can be seen in Figure 3 in the assembled state of the antenna drive device according to the present invention, the rotary contact means 130 is disposed to be inclined at a predetermined angle to the inclined allowable coupling means 120 by an external force applied by the antenna 10. In this state, the elastic force providing means 140 is supported to press one side of the antenna 10. The antenna 10 is supported in line contact or point contact with the antenna support means 160 at two portions near the inner edge of the antenna support means 160.

When power is applied to the rotary driving means 110 in FIG. 3, when the rotary shaft 112 rotates clockwise or counterclockwise, the inclined allowable coupling means 120 coupled to the rotary shaft 112 rotates and protrudes. The rotary contact means 130 interlocked in the rotational direction to the inclined allowable portion 122 via 133 also rotates in a state inclined at a predetermined angle with respect to the rotation shaft 112. As the rotary contact means 130 rotates, the antenna 10 is linearly moved along the rotational direction of the rotation shaft 112 to draw in or draw out. Here, the contact force acting between the rotary contact means 130 and the antenna 10 depends on the spring constant and the degree of compression of the coil spring used, the radius of the coil spring and the like.

In FIG. 3, when the antenna 10 having a larger diameter is assembled, the rotary contact means 130 is slightly inclined with respect to the rotary shaft 112, and the pressing force applied by the rotary contact means 130 to the antenna 10 is A little bigger Of course, when the antenna 10 having a smaller diameter is assembled, the rotary contact means 130 is slightly inclined with respect to the rotary shaft 112, and the pressing force applied by the rotary contact means 130 to the antenna 10 is slightly small. Is further reduced. That is, in the case of using the antenna driving apparatus according to the present invention, even if the diameter of the antenna or its installation position is changed slightly depending on the design of the mobile communication terminal, or the processing error such as the antenna is somewhat present, the rotary contact means 130 and the antenna are present. The force acting between (10) does not change drastically. Therefore, the antenna driving apparatus according to the present invention can be used irrespective of the design type of the mobile communication terminal, the size variation of the antenna, and the like, and can provide a suitable driving condition in any case, thereby dramatically reducing the product defect rate related to the antenna driving. Lower it.

Figure 4 is a partial cutaway perspective view showing a coupling state of the main part of the antenna drive device according to the present invention, Figure 5 is a partial cutaway perspective view showing a coupling state of the main part in the antenna coupled state.

As can be seen in FIGS. 4 and 5, the inclined allowable coupling means 120 is coupled to the rotating shaft 112 of the rotary driving means 110, and the rotary contact means 130 allows the inclined through the protrusion 133. It is coupled to the inclined allowable portion 122 of the coupling means 120, the elastic force providing means 140 is coupled between the inclined allowable coupling means 120 and the rotary contact means 130. The rotation driving means 110 is coupled to the housing 160a having an antenna hole 162 serving as the antenna support means 160. The housing 160a surrounds and protects the inclined allowable coupling means 120, the rotation contact means 130, and the elastic force providing means 140, supports the antenna 10, and rotates the rotation contact means through the long hole 164. Guide 130).

As can be seen in Figure 4 in the state in which the antenna 10 is not coupled to the rotary contact portion 130 of the antenna drive device 100 according to the present invention is arranged in the same line as the rotary shaft 112, the rotary shaft 112 Are not inclined relative to However, as shown in FIG. 5, when the antenna 10 is inserted into the antenna hole 162 and assembled, the rotation contact means 130 is pushed to one side by the antenna 10 and disposed to be inclined at a predetermined angle with respect to the rotation shaft 112. . The rotary contact means 130 in FIG. 5 is subjected to a force to be restored to the state as shown in FIG. 4 by the elastic force providing means 140.

6 is a perspective view showing a modification of the antenna driving apparatus according to the present invention, Figure 7 is an exploded perspective view of the antenna driving apparatus of FIG.

That is, in the case of the previous embodiment, the housing 160a is fixedly coupled to the body of the motor 110a, such that bending is not allowed. In contrast, in this modification, the housing 160b and the motor 110a are coupled in such a manner as to be bent at a predetermined angle. Specifically, as shown in FIGS. 6 and 7, the protrusion 116 is formed on one outer circumferential surface of the geared motor 110a constituting the rotation driving means 110, and the housing constituting the antenna support means 160 ( The groove 168 is coupled to the protrusion 116 to allow the housing 160b to rotate at a predetermined angle. In order to allow the antenna support means 160 to be bent in the vertical direction (z direction) with respect to the motor 110a placed in the horizontal direction (y direction), the groove 168 extends from the edge of the housing 160b. It is preferable that the protrusions 116 and the grooves 168 are arranged at 180 ° intervals, respectively. Furthermore, it is preferable to further form a protrusion 169 between the two grooves 168 to limit the bending angle of the housing 160b or to prevent it from being peeled off from the motor 110a. According to this structure, the antenna support means 160 can be rotated with respect to the geared motor 110a within a predetermined angle range. Of course, the projections 116 and the grooves 168 may be formed by changing their positions.

6 and 7 is advantageous in the case where it is difficult to be arranged in line with the geared motor 110a due to the obstacle of the arrangement position of the housing 160b or the circumstances of the allowable installation space. 6 shows the rotational state of the housing 160b.

That is, in the rotary contact means 130b made of elastic material, a part connected to the rotary shaft 12 serves as the elastic coupling means 170b so that the rotary contact means 130b is inclined with respect to the rotary shaft 112. The antenna 10 may be moved while being in contact with the antenna 10.

The cost of terminal development can be reduced.

In addition, even if the diameter of the antenna, the diameter of the rollers, the roundness, the installation position of the antenna driving device, etc. are not accurate, the contact pressure between the rotating contact means and the antenna does not become too large or too small. Is very low, the driving of the antenna is made very smoothly.
