Abstract

PURPOSE: A pipe structure of a multilevel antenna is provided to prevent the over insertion of an inner antenna into the inside of an outer antenna pipe since an inner antenna pipe is inserted only to the location of a groove of the outer antenna pipe. CONSTITUTION: An outer antenna pipe(300) comprises a movement preventing protrusion(310). The movement preventing protrusion prevents the movement of the inner antenna pipe. The movement preventing protrusion is formed along the inner surface of the outer antenna pipe. A ring-shaped projection of the movement preventing protrusion is installed inside the outer antenna pipe. Multiple protrusions are formed along the inner surface of the outer antenna pipe. The movement preventing protrusion welds the protrusion with the inside of the outer antenna pipe. The protrusion is formed along the inner surface since pressure is applied along the outer surface of the outer antenna pipe.

Description

Pipe structure of stacked antenna

The present invention relates to a pipe structure of a multi-stage antenna, and more particularly, to form a ring-shaped groove along a cylindrical outer circumferential surface of the antenna pipe so that the inner antenna pipe is inserted only to the position where the groove of the outer antenna pipe is formed when the multi-stage antenna is folded. It relates to a pipe structure of a multi-stage antenna.

Antennas may be classified in various ways, but may be classified into an external antenna formed by protruding to the outside of the main body and an internal antenna provided inside the main body and not protruding to the outside according to its shape.

In addition, the external antenna is a retractable antenna that extends its length by pulling in an outward direction of the main body, and a part of the antenna is protrudingly formed on one side of the main body, but the fixed type is fixed without being able to extend its length. It can be distinguished by an antenna.

Recently, fixed antennas are used more than retractable antennas, and internal antennas are used more than external antennas. However, due to the inherent advantages of retractable antennas, the demand for retractable antennas is still maintained.

For example, a fixed antenna or a built-in antenna has a limitation on the frequency bandwidth in receiving a signal because the length of the antenna cannot be arbitrarily changed by the user. That is, the fixed antenna and the built-in antenna can not receive a signal outside a specific band by its shape alone. In addition, in the case of the built-in antenna, since the antenna is provided inside the main body, signal interference may occur due to a hand of a user holding the main body, thereby reducing reception sensitivity.

On the other hand, the retractable antenna has a somewhat lower limit on the frequency bandwidth because the user can arbitrarily extend its length, and the reception sensitivity is also higher than that of the fixed antenna or the built-in antenna.

Meanwhile, a stacked antenna such as a retractable antenna may adjust its length by overlapping or unfolding a plurality of antenna pipes having different diameters, and each inner antenna pipe may correspond to an adjacent outer antenna pipe. The order of emission is not a problem, but the order in which the inner antenna pipe is inserted into the outer antenna pipe may be a problem.

That is, according to the order in which the antenna pipes are folded, the inner antenna pipe may be excessively inserted into the adjacent outer antenna pipe.

Here, a component such as a spring for generating a friction force may be present between the inner antenna pipe and the outer antenna pipe. If the inner antenna pipe is excessively inserted into the outer antenna pipe as described above, the components may be separated.

Accordingly, there is a need for the emergence of an invention that prevents the inner antenna pipe from being excessively inserted into the outer antenna pipe in the multistage antenna.

An object of the present invention is to form a ring-shaped groove along the cylindrical outer circumferential surface of the antenna pipe so that the inner antenna pipe is inserted only up to the position where the groove of the outer antenna pipe is formed when the multi-stage antenna is folded.

The objects of the present invention are not limited to the above-mentioned objects, and other objects which are not mentioned will be clearly understood by those skilled in the art from the following description.

In order to achieve the above object, a pipe structure of a multi-stage antenna according to an embodiment of the present invention, in the multi-stage antenna consisting of an inner antenna pipe and an outer antenna pipe, at one end of the inner antenna pipe that meets the inner surface of the outer antenna pipe And a movement preventing protrusion provided inside the outer antenna pipe to prevent movement of the locking means on the locking means and the movement path of the locking means.

Specific details of other embodiments are included in the detailed description and the drawings.

By forming a ring-shaped groove along the cylindrical outer circumferential surface of the antenna pipe as described above, when the multi-stage antenna is folded, the inner antenna pipe is inserted only to the position where the groove of the outer antenna pipe is formed, so that the inner antenna pipe is inward of the outer antenna pipe. There is an advantage of preventing excessive insertion.

1 is a view showing that the antenna pipes of the multi-stage antenna are sequentially inserted.
2 is a view showing that the antenna pipe of the multi-stage antenna is inserted out of sequence.
3 is a view showing a pipe structure of a multi-stage antenna according to an embodiment of the present invention.
4 is a view showing that the movement of the inner antenna pipe is prevented by the movement preventing projection according to an embodiment of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing that the antenna pipes of the multi-stage antenna are sequentially inserted.

The stacked antenna 100, such as a retractable antenna, means that a plurality of straight antenna pipes 110, 120, 130, 140, and 150 having different diameters overlap each other. .

For example, the first antenna pipe 110 with the smallest diameter can be inserted into the second antenna pipe 120 with the second diameter, and the second antenna pipe 120 can be larger than that. It may be inserted into the third antenna pipe 130 having a diameter.

Here, the second antenna pipe 120 and the third antenna pipe 130 preferably have a hollow shape so that the first antenna pipe 110 and the second antenna pipe 120 can be inserted, respectively, Antenna pipe 110 may or may not be hollow in shape.

The multi-stage antenna 100 is a stack of a plurality of antenna pipes 110, 120, 130, 140, 150 to improve the directivity or gain of the antenna, the reception characteristics may vary depending on the length of the unfolded antenna. . That is, it is preferable to vary the length of the unfolded antenna according to the frequency band, so that the user can adjust the length of the multi-stage antenna 100 in order to receive the signal of the desired frequency band.

On the other hand, in order to extend or shorten the length of the multi-stage antenna 100, the user can pull or push the antenna head 160 attached to the above-described first antenna pipe 110, at this time, the adjacent overlapping antenna pipe If there is no friction between the users will not be able to maintain the antenna to the desired length.

For example, even if the user pulls the first antenna pipe 110 to increase the length of the antenna disposed in a direction perpendicular to the ground surface, if there is no friction force between the first antenna pipe 110 and the second antenna pipe 120. The first antenna pipe 110 is to be returned to its original position by gravity.

Accordingly, in order to reduce the influence of gravity or other external factors, it is necessary to generate a friction force between the antenna pipes. For this purpose, a spring is inserted between the contact surfaces of the antenna pipes.

For example, it is provided with a cylindrical spring surrounding the outer surface of the inner antenna pipe, and the center outer peripheral surface of the spring is projected outward so as to contact the inner surface of the outer antenna pipe.

As the spring is inserted, the friction force between the inner antenna pipe and the outer antenna pipe is generated so that the user can adjust the length of the antenna as much as he / she wants.

On the other hand, such a spring is present between the two overlapping antenna pipes, the friction force generated by each spring is different from each other. For example, the friction force generated by the spring between the first antenna pipe 110 and the second antenna pipe 120 and the spring between the second antenna pipe 120 and the third antenna pipe 130 are different from each other.

As the frictional force is different from each other, in order to extend or shorten the length of the antenna, the order in which the antenna pipes overlap or unfold with each other may be formed differently.

For example, when the frictional force by the spring between the first antenna pipe 110 and the second antenna pipe 120 is less than the frictional force by the spring between the second antenna pipe 120 and the third antenna pipe 130. Assume that, when extending the length of the antenna, after the first antenna pipe 110 is unfolded in the second antenna pipe 120, the second antenna pipe 120 is unfolded in the third antenna pipe 130, and When the length is shortened, the second antenna pipe 120 is inserted into the third antenna pipe 130 after the first antenna pipe 110 is inserted into the second antenna pipe 120.

1 shows that the length of the multi-stage antenna 100 is shortened. In a state in which all the antenna pipes 110, 120, 130, 140, and 150 are unfolded (S10), the first antenna pipe 110 is connected to the second antenna pipe. The second antenna pipe 120 is inserted into the third antenna pipe 130 after being inserted into S120 (S20), and the third antenna pipe 130 is inserted into the fourth antenna pipe 140. After the step S40, the fourth antenna pipe 140 is inserted into the fifth antenna pipe 150 (S50).

The frictional force by the spring between the first antenna pipe 110 and the second antenna pipe 120 is the smallest, and the frictional force by the spring between the fourth antenna pipe 140 and the fifth antenna pipe 150 is the largest. It can be understood that.

However, in order to extend the length of the antenna, the order in which the antenna pipes are unfolded is not a big problem, but in order to shorten the length of the antenna, the order in which the antenna pipes overlap may be a problem. That is, one of the antenna pipes may be excessively inserted into the adjacent antenna pipe.

In general, the antenna pipes of the multi-stage antenna 100 have different diameters but their lengths are similarly formed. Therefore, the length in which two or more antenna pipes overlap is generally formed larger than the length of one antenna pipe.

FIG. 2 shows that the antenna pipe of the multi-stage antenna 100 is inserted out of order. The frictional force of the spring between the first antenna pipe 110 and the second antenna pipe 120 (hereinafter, referred to as a first friction force) will be described. ) Is similar to the frictional force (hereinafter referred to as the second frictional force) by the spring between the second antenna pipe 120 and the third antenna pipe 130, the first frictional force and the second frictional force is the third antenna pipe ( The case where the friction force by the spring between the 130 and the 4th antenna pipe 140 (henceforth 3rd friction force) is formed is shown.

As such, as the third friction force is smaller than the first friction force and the second friction force, the first antenna pipe 110 and the second antenna pipe 120 are respectively the second antenna pipe 120 and the third antenna pipe 130. It is inserted into the fourth antenna pipe 140 without being inserted into it. In general, the user tries to push the antenna head 160 until the length of the antenna is completely shortened, while the first antenna pipe 110 is Since the length of the second antenna pipe 120 and the third antenna pipe 130 unfolded is longer than the length of the fourth antenna pipe 140, the inner end of the third antenna pipe 130 is the fourth antenna pipe 140. The insertion may be past the inner one end of the.

As described above, a spring is provided between two antenna pipes overlapping each other, and the spring is supported on the inner and outer surfaces of the two antenna pipes to maintain its shape and position.

However, when the inner one end of the third antenna pipe 130 is inserted past the inner one end of the fourth antenna pipe 140 as above, it exists between the third antenna pipe 130 and the fourth antenna pipe 140. The spring may be out of position.

In addition, since the spring existing between the third antenna pipe 130 and the fourth antenna pipe 140 is not supported by the inner surface of the fourth antenna pipe 140 even if the spring does not deviate from its position, its shape is deformed. Therefore, it may not be easy to be inserted into the fourth antenna pipe 140 again.

In order to prevent this, the antenna pipe according to the embodiment of the present invention may be provided with a movement preventing protrusion 310 to prevent the antenna pipe inserted into the inside thereof to be separated as described above.

3 is a view showing a pipe structure of a multi-stage antenna according to an embodiment of the present invention.

As described above, the multi-stage antenna 100 means that the plurality of straight antenna pipes 110, 120, 130, 140, and 150 having different diameters are formed to overlap each other. One is inside and the other is outside. In other words, the smaller diameter antenna pipe is inserted into the larger diameter antenna pipe.

As such, when the multi-stage antenna 100 only sees two antenna pipes overlapped with each other, it can be seen that one can be provided on the inside and the other can be provided on the outside. The antenna pipe provided on the outside is referred to as an outer antenna pipe 300.

The first antenna pipe 110, the second antenna pipe 120, and the third antenna pipe 130 described above will be described as an example, and a first antenna between the first antenna pipe 110 and the second antenna pipe 120 is described. The relationship between the pipe 110 being the inner antenna pipe and the second antenna pipe 120 being the outer antenna pipe 300 can be established.

However, the relationship between the second antenna pipe 120 and the third antenna pipe 130 is that the second antenna pipe 120 is the inner antenna pipe, and the third antenna pipe 130 is the outer antenna pipe 300. .

In other words, based on the second antenna pipe 120, it is determined whether the inner antenna pipe or the outer antenna pipe 300 depends on whether it is wrapped around another antenna pipe or inserted into the other antenna pipe.

FIG. 3 shows the structure of the outer antenna pipe 300 and shows that the inner antenna pipe 300 includes a movement preventing protrusion 310 to prevent the inner antenna pipe from escaping from its position.

Here, the movement preventing protrusion 310 may be understood to be formed along the inner circumferential surface of the outer antenna pipe 300, for example, a ring-shaped protrusion may be provided inside the outer antenna pipe 300. In addition, the movement preventing protrusion 310 may be formed along the inner circumferential surface of the outer antenna pipe 300, a plurality of protrusions having a point shape rather than one continuous protrusion like a ring.

Various methods for forming the movement preventing protrusion 310 may exist. For example, the movement preventing protrusion 310 may be formed by inserting and attaching the protrusion to the inside of the outer antenna pipe 300. As shown in FIG. 2, protrusions may be formed along the inner circumferential surface by bending the pressure along the outer circumferential surface of the outer antenna pipe 300.

In the present invention, the antenna pipe may be understood as having a cylindrical shape. If each antenna pipe is viewed as the outer antenna pipe 300, it has two inlets and outlets into which other antenna pipes are inserted or discharged. That is, circular inlet and outlet are provided in the both ends of the long axis of a cylinder.

In addition, it can be understood that the multi-stage antenna according to the embodiment of the present invention is attached to a terminal using the same for transmitting and receiving signals. When the multi-stage antenna is completely shortened, one end of all the antenna pipes is generally located inside the terminal. The other end is located outside the terminal.

Accordingly, one end of the two ends of each antenna pipe, which is located inside the terminal, is called the inner end, and one end of the outside of the terminal is called the outer end.

The movement preventing protrusion 310 may be formed by approaching an inner end of the outer antenna pipe 300. The movement preventing protrusion 310 is for preventing the inside end of the inner antenna pipe from moving further by being caught. When the movement preventing protrusion 310 is formed to be excessively separated from the inner end of the outer antenna pipe 300. This is because the length by which the inner antenna pipe can be inserted is reduced.

In addition, since the inner end of the inner antenna pipe cannot move to the inner end of the outer antenna pipe 300 as it is caught by the movement preventing protrusion 310, the outer end of the inner antenna pipe and the outer end of the outer antenna pipe 300. It is preferable to make the length of the inner antenna pipe shorter than the length of the outer antenna pipe 300 in order to be aligned at the same position with respect to this long axis.

Here, the difference between the lengths of the inner antenna pipe and the outer antenna pipe 300 may be determined by the lengths of the movement preventing protrusion 310 and the inner end of the outer antenna pipe 300.

As such, as the lengths of the inner antenna pipe and the outer antenna pipe 300 are different from each other, the length of the first antenna pipe 110 is formed to be the shortest in the antenna structure of FIGS. 1 and 2, and the fifth antenna pipe ( The length of 150 may be formed longest.

4 is a view showing that the movement of the inner antenna pipe is prevented by the movement preventing projection according to an embodiment of the present invention.

The inner antenna pipe 400 may have a locking means 420 at one end of the inner antenna pipe 400 that meets the inner surface of the outer antenna pipe 300, wherein the locking means 420 is an inner antenna pipe 400. It can be formed by bending the corner of one end outward.

Here, the locking means 420 may be formed at the inner end of the inner antenna pipe 400, and the locking means 420 may be used to prevent the spring attached to the inner antenna pipe 400 from leaving its position. It may be used as.

As shown in FIG. 4, the inner antenna pipe 400 may move freely in the long axis direction inside the outer antenna pipe 300, and the locking means 420 may prevent the movement of the outer antenna pipe 300. When it meets with and can no longer move toward the terminal, the inner end of the inner antenna pipe 400 is prevented from moving toward the inside of the terminal past the inner end of the outer antenna pipe 300.

Meanwhile, although the antenna pipe 400 provided on the inside of the two overlapped antenna pipes shown in FIG. 4 is referred to as the inner antenna pipe, and the antenna pipe 300 provided on the outside is referred to as the outer antenna pipe, As one may determine, the criterion for determining the inner antenna pipe or the outer antenna pipe depends on whether it encloses another antenna pipe or is inserted into another antenna pipe.

In other words, when the outer antenna pipe 300 shown in FIG. 4 is inserted into the inside of another antenna pipe, it is an inner antenna pipe, and accordingly, may have a locking means 320 as shown in the drawing. 320 may limit movement of the outer antenna pipe 300 by being caught by a movement preventing protrusion (not shown) provided in another antenna pipe (not shown) surrounding the outer antenna pipe 300 of FIG. 4.

Similarly, if the inner antenna pipe 400 shown in FIG. 4 surrounds another antenna pipe (not shown), the inner antenna pipe 400 is an outer antenna pipe, and thus may include a movement preventing protrusion 410. 410 may limit the movement of the locking means (not shown) of the other antenna pipe (not shown) inserted into the inner antenna pipe 400.

Although embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features thereof. You will understand that. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
