In particular, the track body 310 may include a plurality of protruding structures 311, and each ball guide rail 320 may include a plurality of engaging grooves 321, and a part of the protruding structure 311 is engaged with the engaging groove 321 of a ball guide rail 320. The protruding structure The other part of 311 is engaged with the engaging groove 321 of another ball guide rail 320 .

具體而言，凸起結構311可沿線性滑塊滑動的方向(即軸向)分別在軌道本體310的二內側間隔排列。透過凸起結構311卡合於滾珠導軌320的卡合槽321，可增加軌道本體310與滾珠導軌320結合的強度，避免滾珠導軌320因外力而脫落於軌道本體310。再者，滾珠導軌320可以膠合方式固定於軌道本體310，但本發明不以此為限。Specifically, the protruding structures 311 can be arranged at intervals on two inner sides of the track body 310 along the direction in which the linear slider slides (ie, the axial direction). By engaging the protruding structure 311 with the engaging groove 321 of the ball guide rail 320, the strength of the combination between the track body 310 and the ball guide rail 320 can be increased, thereby preventing the ball guide rail 320 from falling off the track body 310 due to external force. Furthermore, the ball guide rail 320 can be fixed to the track body 310 by gluing, but the invention is not limited thereto.

值得說明的是，其他實施例中，可以是滾珠導軌包含凸起結構，且軌道本體的內側設置對應凸起結構的卡合槽，本發明不以此為限。It is worth noting that in other embodiments, the ball guide rail may include a protruding structure, and an engaging groove corresponding to the protruding structure is provided on the inside of the track body. The present invention is not limited to this.

綜上所述，本發明提供了一種線性滑塊及致動裝置，其具有下列優點：第一，透過非金屬複合材料製成的第二組件及軌道本體，可輕量化線性滑塊及致動裝置，並透過金屬材料製成的第一組件及滾珠滑軌，維持滾珠滾動的流暢度；第二，透過支撐件的配置，可分散第二組件承受的外力，降低第二組件損壞的可能；以及，第三，透過熱壓接合的方式結合金屬材料及非金屬複合材料製成的部件，可進一步增加結合的強度。To sum up, the present invention provides a linear slider and an actuator device, which have the following advantages: first, through the second component and the track body made of non-metallic composite materials, the linear slider and the actuator can be lightweight device, and maintains the smoothness of ball rolling through the first component and ball slide rail made of metal materials; secondly, through the configuration of the support, the external force endured by the second component can be dispersed, reducing the possibility of damage to the second component; And, thirdly, combining components made of metallic materials and non-metallic composite materials through thermocompression bonding can further increase the strength of the bond.
