The base A1 is a U-shaped structure having a gap A11. The cover A5 covers the gap A11 and is fixed to the belt A4 so that the cover A5 is moved together with the slide block A3 and some components which need to be driven by the belt A4, (A4). ≪ / RTI > Due to the shape of the base A1, the direction in which the cover A5 and the belt A4 are assembled is limited. For example, the base A1 is provided with a single gap A11 in only one direction, and therefore, the cover A5 must be disposed at the position of the gap A11, and the assembling direction of the belt A4 is also limited . As a result, the direction of the motor M for rotating the belt A4 is also limited. As shown in Fig. 1, the motor M may be disposed only on the left or right side of the base A1. Due to limitations in the direction of assembly of each component, the overall device is also limited in terms of coverage and installation space.

The present invention seeks to eliminate and / or mitigate the above-mentioned disadvantages.

The present invention will become more apparent from the following description taken in conjunction with the accompanying drawings, which illustrate, by way of illustration only, a preferred embodiment of the invention.

2 to 5, a belt drive linear actuator according to a preferred embodiment of the present invention includes a base 10, a linear movable unit 20, a belt drive unit 30, a first cover 40, A cover 50, a driving source 60, and a slide block 70.

The direction of connection between the two ends of the base 10 is defined as the longitudinal direction L. [ The base 10 is an L-shaped structure having a first assembly part 11 and a second assembly part 12 connected to each other. Each of the first assembly portion 11 and the second assembly portion 12 is a sheet structure. The first assembly portion 11 extends at least in the longitudinal direction L and in the width direction W. [ The second assembly portion 12 extends at least in the longitudinal direction L and the height direction H. The width direction W is perpendicular to the longitudinal direction L and the longitudinal direction L is perpendicular to the width direction W and the longitudinal direction H. [ The base 10 has a width W10 in the width direction W and a height H10 in the height direction H and W10 is equal to H10.

The end face of the first assembly part 11 which is not connected to the second assembly part 12 is defined as the first connection end face 111 and the end face of the second assembly part 11 that is not connected to the first assembly part 111 12 is defined as a second connection end face 121. [

The linear movable unit 20 is fixed between the first and second assembling parts 11 and 12. [ That is, the linear movable unit 20 can be selectively fixed on the first or second assembly portion 11, 12. The linear movable unit 20 includes a linear movable member 22 which is linearly movable along the guide member 21 and the guide member 21. [

The belt drive unit 30 includes a belt 31, an assembling seat 32, and two pulley sheets 33. The assembly sheet 32 is fixed to the linear movable member 22 of the linear movable unit 20. Each of the two pulley sheets 33 includes an assembly hole 331 passing through both ends and a pulley 332 rotatably arranged in the assembly hole 331. Two pulleys 332 are located at the two ends of the base 10. The belt 31 is fixed to the assembly sheet 32 and wound around the pulleys 332 of the two pulley sheets 33.

The first cover 40 is a flat plate that is removably disposed on the base 10.

The second cover 50 is an L-shaped flat plate. The first and second covers (40, 50) are removably disposed on the first and second connecting end faces (111, 121). That is, when the first cover 40 is disposed on the first connecting surface 111, the second cover 50 is disposed on the second connecting end surface 121, and vice versa. The second cover (50) includes a cover portion (51) and an auxiliary portion (52) connected to each other. The cover portion 51 has a height S1 measured from one end of the cover portion 51 connected to the auxiliary portion 52 to the other opposite end of the cover portion 51 and S1 = W10 = H10. The auxiliary portion 52 has a height S2 measured from one end of the auxiliary portion 52 connected to the cover portion 51 to the other opposite end of the auxiliary portion 51, S2 < S1. The cover portion (51) is connected to the base (10). When the second cover 50 is connected to the base 10, the auxiliary portion 52 forms a gap P with respect to the first cover 40.

The drive source 60 is coupled to one of the pulleys 332 to rotate the belt drive unit 30. [

The slide block 70 has a connecting portion 71 which is inserted into the gap P and fixed to the assembly seat 32 of the belt drive unit 30 so as to move with the linear movable member 22. The slide block 70 is provided for supporting the device to be driven and moved. The slide block 70 may be disposed on any surface of the assembly sheet 32.

The guide member 21 and the linear movable member 22 of the linear movable unit 20 are not limited by the shape or the shape. For example, as shown in Fig. 3, the guide member 21 and the linear movable member 22 of the linear movable unit 20 are connected to the guide member 21A in the form of a rail and the linear movable member 22A ). The linear movable member 22A is linearly movable along the guide member 21A.

14, the guide member 21 and the linear movable member 22 of the linear movable unit 20 also have a guide member 21B in the form of a rail and a plurality of rollers 222 , And a linear movable member 22B in the form of a roller sheet. The roller 222 is clamped against the two sides of the seat body 221 such that the linearly movable member 22B is linearly movable along the guide member 21B.

As shown in Fig. 15, the guide member 21 and the linear movable member 22 of the linear movable unit 20 further include a guide member 21C in the form of a rail having a spherical cross section 211, 223). The linear movable member 22C may be a sliding block type linear movable member 22C. The spherical guide member 21C is movably inserted into the linear movable member 22C so that the linear movable member 22C is linearly movable along the guide member 21C.

The drive source 60 rotates one of the pulleys 332 and rotation of the pulleys 332 causes rotation of one of the pulleys 332 and the belt 31. In this manner, the belt 31 drives the assembly sheet 32 to move, and the assembly sheet 32 drives the linear movable member 22 to move linearly along the guide member 21. [ On the other hand, the slide block 70 on the assembly sheet 32 is also caused to move linearly while supporting the device mounted on the top.

An important point is the advantage produced by the structural form of the base 10. In addition to the first and second covers 40 and 50 being removably disposed on the base 40, the base 10 may include an L-shaped member having a first assembly 11 and a second assembly 12, Shape assembly, the present invention can be applied to other forms as follows.

First, the gap P (P) formed between the first and second covers 40 and 50 is changed by merely changing the assembling portion of the first and second covers 40 and 50 without changing the arrangement direction of the base 10 So that the assembling direction of the slide block 70 and the assembling position of the apparatus mounted on the slide block 70 can be changed as a result. Therefore, as shown in Figs. 4 and 5, the driving source 60 can be assembled in the other direction.

6 and 7, when the second assembly 12 is fixed to the same assembly surface X, by merely changing the direction of the base 10, the direction of installation or assembly of the drive source 60 Can be changed. 8 and 9, disposing the first assembly portion 11 on another assembly surface X can also change the assembling direction of the drive source 60. [ 10 to 13, the driving source 60 is also positioned or changed in direction by changing the orientation of the belt 31, the base 10, and the first and second covers 40 and 50 .

In summary, in addition to the size limitations for the components described above, the first and second covers 40, 50 are removably disposed with the first and second covers removably disposed on the L-shaped base 10, So that the slide block 70 can be assembled in the other direction and the limitation on the assembling direction of the drive source 60 can be reduced. In addition, the width W10 of the base 10 is equal to the height H10 of the base 10 and the height S1 of the cover is equal to the height H10 and width W10 of the base 10, (10) can be assembled in the same position with the other directions, and thus the range of application of the entire apparatus of the present invention and the degree of freedom of the assembly portion are improved.

While various embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that there may be additional embodiments within the scope of the present invention.
