In this embodiment, the linear track body 2 includes a bottom plate 21 and two side walls 22. The side walls 22 are respectively disposed on two sides of the bottom plate 21, and the side walls 22 and the bottom plate 21 surround an accommodation space SP. Each of the side walls 22 has at least one track groove 221 and at least one fixing portion 222. The track grooves 221 are disposed opposite to each other, and each of the fixing portions 222 is respectively disposed on the side wall 22. The side wall 22 further has a first surface 223 and a second surface 224, the second surface 224 is connected to the bottom plate 21, and the first surface 223 and the second surface 224 are disposed correspondingly.

As shown in FIG. 3B, the fixing portion 222 is a perforated structure O1, and the perforated structure O1 penetrates the first surface 223 and the second surface 224. The fixing portion 222 may be a screw hole or an opening, and the shape of the radial section of the opening is circular, polygonal, or irregular (not shown). When the fixing portion 222 is a screw hole, a screw can penetrate the first surface 223 and the second surface 224 of the side wall 22, and then connect the screw holes of the external structure to lock the linear track body 2 and the external structure. In addition, when the fixing portion 222 is an opening, a positioning post having the same shape as the radial cross section of the opening may be used to penetrate the first surface 223 and the second surface 224 of the side wall 22 and interfere with the fixing portion 222. Then it cooperates with the opening of the external structure to connect the linear track body 2 with the external structure. Among them, after the opening is filled with solder, interference fit is performed with the positioning post, so that the positioning post and the opening can be more firmly combined.

In addition, as shown in FIG. 3C, according to the assembly design of the linear track body 2a and the external structure, the fixing portion 222a may be designed as a blind hole structure O2, and the blind hole structure O2 is adjacent to the outside The second surface 224a of the structure extends toward the first surface 223a, but does not exceed the first surface 223a. The fixing portion 222 a may be a screw hole or an opening, and the shape of the radial section of the opening is circular, polygonal, or irregular (not shown). When the fixing portion 222a is a screw hole, a screw can be used to penetrate the screw hole of the external structure, and then be locked into the blind hole structure O2 of the second surface 224a, so that the linear track body 2a is locked with the external structure. In addition, when the fixing portion 222a is an opening, a positioning post having the same shape as the radial cross-section of the opening can be used to interfere with the opening of the external structure, and then penetrate into the second surface 224a of the side wall 22a and be fixed to the fixing.

In this embodiment, the design of the fixing portion 222 directly provided on the side wall 22 of the linear orbit body 2 allows the linear orbit body 2 to be assembled directly with other components of the linear drive module L at the factory. The L-lock of the linear transmission module needs to be fixed on the external structure or the workbench, and the subsequent assembly process can be directly performed without additional assembly and transportation processes. Therefore, the manufacturing cost can be reduced, the assembly and transportation processes and time can be reduced, and at the same time, the assembly accuracy and stability of the linear track body L and the external structure can be improved. And because the range of the locking position of the fixing portion 222 is larger than the reciprocating path of the slide 4, the ability of the linear track body 2 to resist the impact of the slide 4 can be increased, the stability of the system operation can be improved, and the overall system assembly strength can be increased.

The following further describes the anti-sliding impact capability of the conventional linear orbit and the original linear orbit. Please refer to FIG. 7A and FIG. 7B at the same time. FIG. 7A is the conventional linear orbit 9 shown in FIG. 1. FIG. 7B is a schematic cross-sectional view of the relationship of the impulse-resistance, FIG. 7B is a schematic cross-sectional view of the relationship of the impulse-resistance of the linear track body 2 shown in FIG. 3A. In addition, in order to keep the drawing simple and easy to explain the creation, FIG. 7A and FIG. 7B only show the cross-section lines on one side to clearly illustrate the force-resistance relationship, and the forces F3, F3 ', and resistance F4 of FIGS. 7A and 7B. , F4 'only shows the horizontal component force on one side, and the position where the impulse or resistance occurs only shows the centroids C3, C3', C4, and C4 'of the track groove and the screw S on the fixing part, which is Where the position vectors r3, r3 ', r4, r4' point in the figure.

As shown in FIG. 7A, when a sliding seat (not shown) hits one side of the track groove 921, the centroid C3 of the track groove generates a horizontal horizontal force F3 to the right, and the center of the linear track body 9 The intersection point of the center line and the bottom plate 91 is the fulcrum point P, and the impulse force F3 and the position vector r3 together generate an impulse moment in one direction. Similarly, when the orbital groove 921 collides, the centroid C4 of the screw hole 911 generates a horizontal resistance F4 to the left, and the resistance F4 and the position vector r4 use the fulcrum P as the center of rotation to generate a resistance moment in a direction opposite to the impulse moment. . Since the screw hole 911 is provided on the bottom plate 91 of the linear track body 9, the position vector r4 of the resistance moment is smaller than the position vector r3 of the impact moment, the screw S must generate a greater resistance F4 than the impact force F3 to balance the impact moment. Therefore, if the locking ability of the screw S and the screw hole 911 cannot bear the impact moment generated by the impact of the track groove 921, the screw S will be loosened, causing the track groove 921 to move.

Continuing to refer to FIG. 7B again, when the slide 4 (not shown) hits the side track groove 221, the centroid C3 ′ of the track groove generates a horizontal impulse F3 ′ to the right, and the center line of the linear track body 2 The intersection point with the bottom plate 21 is the fulcrum point P ′, and the impulse force F3 ′ and the position vector r3 ′ together generate an impulse moment in one direction. Similarly, when the orbital groove 221 collides, the centroid C4 'of the screw S in the fixed portion 222 generates a horizontal resistance F4' to the left, and the resistance F4 'and the position vector r4' jointly use the fulcrum P 'as the rotation center. A resistance moment is generated in the opposite direction to the impulse moment. Since the fixing portion 222 of the linear track body 2 of this embodiment is disposed on the side wall 22, the range of the locking position of the fixing portion 222 is larger than the reciprocating path of the slide 4, so that the position vector r4 'of the resistance moment is greater than the position of the impact moment The vector r3 ', the screw S can generate a small resistance F4', which can balance the impact of the impact moment, making the linear track body 2 resistant to the impact of the slide 4 and increasing the stability of the system operation, and increasing the overall system assembly strength.
