[0035] Please refer to Figures 1 to 15. An embodiment of the present invention provides a track system 100, including a track 200 and a module assembly 300. The track 200 is mounted on a mounting base, and the module assembly 300 is snap-fitted onto the track 200. The module assembly 300 can be a lamp, camera, electrical accessory, sensor, controller, etc., and is not limited thereto. The track 200 can consist of a single track 200 or can be constructed by splicing together multiple tracks 200.

[0036] In some embodiments, a module assembly 300 is mounted on the track 200.

[0037] In other embodiments, multiple module components 300 are mounted on the track 200, and the module components 300 may be spaced apart or arranged adjacent to each other.

[0038] Please refer to Figures 1 to 5. In this embodiment, the track system 100 consists of two spliced ​​tracks 200, and a module assembly 300 is installed on each track 200. The two module assemblies 300 are arranged adjacent to each other at the splicing point of the two tracks 200. The longitudinal direction is defined as the length extension direction of the track 200. A waterproof end cap 400 is provided on the second end 2009 of the track 200 along the longitudinal direction, and the waterproof end cap 400 is sealed to both the track 200 and the module assembly 300.

[0039] Specifically, the waterproof end cap 400 contains a wire guide plug 4001 and a sealing block 4002. The wire guide plug 4001 guides and secures the wires within the track system 100. The sealing block 4002 is made of a waterproof flexible material, such as rubber or silicone. The sealing block 4002 is at least partially located at the contact point between the track 200 and the module assembly 300 at the second end 2009, and is press-fitted with both the track 200 and the module assembly 300.

[0042] A track splicing sealing assembly 2006 is fitted over the outer side of the joint between the two tracks 200, covering the joint to achieve waterproofing on the outside. The track splicing sealing assembly 2006 includes a track splicing sealing plate 2061 and a track splicing sealing element 2062. The track splicing sealing plate 2061 engages with the track 200, and the track splicing sealing element 2062 is sandwiched between the track splicing sealing plate 2061 and the track 200. The track splicing sealing element 2062 is made of a flexible waterproof material. The track splicing sealing element 2062 has a first mating part 2621, the shape of which matches the first engaging part 2004, ensuring a tight fit between the track splicing sealing element 2062 and the track 200. By pressing the track splicing seal 2062 outward through the track 200, and pressing the track splicing seal plate 2061 inward through the track splicing seal 2062, the track 200 achieves a waterproof seal at the splicing point.

[0043] A sealing plate limiting member 2611 is provided at the bottom of the track splicing sealing plate 2061. The sealing plate limiting member 2611 is engaged with the track 200 to achieve the fixation between the track splicing sealing plate 2061 and the track 200.

[0044] In this embodiment, the sealing plate limiting member 2611 includes a first limiting arm and a second limiting arm connected together. The first limiting arm extends horizontally inward from the side of the track splicing sealing plate 2061, and the second limiting arm extends vertically upward from the first limiting arm. The first limiting arm abuts against the first arm 2051, and the second limiting arm abuts against the second arm 2052, thereby achieving the snap-fit ​​fixation between the sealing plate limiting member 2611 and the track 200.

[0045] Please refer to Figure 10. A connecting plate 2008 is also provided between the two tracks 200, and the two tracks 200 are connected by the connecting plate 2008. The overall shape of the connecting plate 2008 matches the track housing 2001, facilitating installation on the track housing 2001. The connecting plate 2008 is installed on the inner side of the track housing 2001 and abuts against the bottom plate of the track housing 2001. The bottom plate of the track housing 2001 faces the mounting base. Furthermore, the connecting plate 2008 is provided with a second mating part 2081, which matches the shape of the first snap-fit ​​part 2004, facilitating the quick assembly of the connecting plate 2008 onto the track 200.

[0046] A connecting plate 2008 is disposed on the inner side of the track 200 and covers the inner joint of the two tracks 200, achieving waterproofing on the inner side of the joint. Specifically, a connecting bracket 2007 is provided on the connecting plate 2008, located at the joint of the two tracks 200. Furthermore, the connecting bracket 2007 abuts against the side of the third arm 2053 facing the bottom plate of the track housing 2001. A third sealing element 2071 is fitted onto the connecting bracket 2007, located at the joint of the two adjacent tracks 200. The third sealing element 2071 is an annular sealing ring. The annular sealing ring presses against the joint of the two tracks 200 and abuts against the third arm 2053 of the track housing 2001. The third sealing element 2071 is interference-fitted with both tracks 200. Specifically, the connecting bracket 2007 presses downward against the third seal 2071, and the third arm 2053 of the track 200 presses upward against the third seal 2071 to achieve a waterproof seal at the joint of the track 200. This design prevents water from entering the track 200 from the inside of the joint. The connecting plate 2008 and the track joint sealing assembly 2006 work together at the joint to provide double waterproof protection.

[0047] Preferably, a rib is provided on the side of the third seal 2071 facing the third arm 2053 to increase the friction between the third arm 2053 and the third seal 2071, further improving the sealing performance of the inner side of the track 200 at the splice and preventing water from entering the track 200 from the splice.
