DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is described in detail below in combination with the drawings and specific embodiments.

[0024] Here, it needs to be explained that, in order to avoid the present application being obscured by unnecessary details, only the structures and / or processing steps closely related to the scheme of the present application are shown in the drawings, and other details not closely related to the present application are omitted.

[0025] In addition, it also needs to be explained that the term “comprise”, “include” or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or includes elements inherent to such process, method, article or equipment.

[0026] Please refer to Figs. 1-2, which are linear lamps 100 of embodiments of the present application. The linear lamp 100 includes a track, an installation assembly 300, a shell 400 and a lighting assembly 700. The installation assembly 300 is arranged at the end of the shell 400 arranged in the longitudinal direction, and the installation assembly 300 fixes the shell 400 to the installation base 200. The shell 400 is connected with the lighting assembly 700. When the linear lamp 100 is applied in a vertical plane, the lighting assembly 700 is installed on the vertical track through the installation assembly 300.

[0027] Referring to FIG. 3, the track as the mounting base 200 has a mounting groove 210 inside for accommodating the mounting assembly 300, and the housing 400 is at least partially received in the mounting groove 210. The lighting assembly 700 is detachably connected with the track through the mounting assembly 300. The mounting assembly 300 stably fixes the lighting assembly 700 on the track and allows the lighting assembly 700 to be adjusted within a certain range of rotation.

[0028] The top wall 2101 of the mounting groove 210 is provided with a protrusion 2102. The protrusion 2102 is connected with the top wall 2101 and protrudes into the mounting groove 210. The protrusion 2102 includes a bottom surface 2121 facing the housing 400. The mounting assembly 300 includes a shell 3402. The shell 3402 has a mounting surface 310 facing one side of the mounting base 200, and the mounting surface 310 is in close abutment with the bottom surface 2121 of the protrusion 2102.

[0029] Referring to FIGS. 4-6, the mounting surface 310 is provided with an elastic arm 320. The elastic arm 320 includes an opposite fixed end 3201 and a free end 3202. The fixed end 3201 is connected with the mounting surface 310, and the free end 3202 is arranged away from the mounting surface 310. The free end 3202 can be elastically deformed when subjected to an external force, so as to realize the interference abutment between the elastic arm 320 and the bottom surface 2121, thereby enhancing the fastening of the installation.

[0030] In a direction perpendicular to the mounting surface 310, the fixed end 3201 has a first thickness, and the end of the free end 3202 away from the fixed end 3201 has a second thickness, and the first thickness is greater than the second thickness. The thicker design of the fixed end 3201 increases the contact area and connection strength between the fixed end 3201 and the mounting surface 310, so that the elastic arm 320 can withstand greater force. The thinner design of the free end 3202 makes this part more easily deformed when subjected to an external force.

[0031] The fixed end 3201 includes a first surface 3203 facing the mounting base 200, and the free end 3202 includes a second surface 3204 facing the mounting base 200. The first surface 3203 has a first distance from the mounting base 200, and the second surface 3204 has a second distance from the mounting base 200, and the second distance is less than the first distance. That is, the free end 3202 is convex relative to the fixed end 3201 towards the mounting base 200.

[0032] A connecting slope 3205 is arranged between the first surface 3203 and the second surface 3204. The connecting slope 3205 smoothly connects the first surface 3203 and the second surface 3204. The connecting slope 3205 gradually approaches the mounting base 200 from the first surface 3203 to the second surface 3204.

[0033] When the installation assembly 300 is installed on the installation base 200, the first surface 3203, the second surface 3204 and the connecting inclined surface 3205 all form effective abutment with the installation base 200, not only increasing the contact area of the elastic arm 320 with the installation base 200 and improving the stability of the installation, but also dispersing stress concentration through multi-point force, prolonging the service life of the installation assembly 300.

[0034] The shell 3402 of the installation assembly 300 is provided with a relief groove 330 corresponding to the position of the elastic arm 320. When the elastic arm 320 is subjected to the reaction force of the installation base 200, it can deform sufficiently, and the free end 3202 moves towards the relief groove 330 relative to the installation base 200, thereby realizing the effect of interference abutment.

[0035] The relief groove 330 has a groove bottom surface 3301. The fixed end 3201 includes a third surface 3206 facing the relief groove 330, and the free end 3202 includes a fourth surface 3207 facing the relief groove 330. The third surface 3206 and the groove bottom surface 3301 have a third distance therebetween, and the fourth surface 3207 and the second surface 3204 have a fourth distance therebetween, the third distance being greater than the fourth distance. In this way, sufficient space is ensured for the elastic arm 320 to deform, and when the elastic arm 320 is subjected to the force applied by the installation base 200, the elastic arm 320 can be completely pressed into the relief groove 330.

[0036] The fixed end 3201 and the relief groove 330 are further provided with a reinforcing portion 3208. One end of the reinforcing portion 3208 is connected to the third surface 3206, and the other end is connected to the groove bottom surface 3301. The reinforcing portion 3208 serves as an additional support structure to tightly connect the fixed end 3201 and the groove bottom surface 3301, enhancing the rigidity and load-carrying capacity of the elastic arm 320. During the process of repeatedly connecting and disconnecting the installation assembly 300 with the installation base 200, the elastic arm 320 is subjected to external force for a long time and is prone to fatigue failure, and the fixed end 3201 may break. The presence of the reinforcing portion 3208 can reduce the probability of fatigue cracks and prolong the service life of the elastic arm 320.

[0037] When the installation assembly 300 is installed on the installation base 200, the elastic arm 320 abuts against the protruding portion 2102 of the top wall 2101 of the installation groove 210, and when the elastic arm 320 receives the reaction force from the bottom surface 2121 of the protruding portion 2102, the free end 3202 of the elastic arm 320 deforms and moves towards the relief groove 330 until the bottom surface 2121 of the protruding portion 2102 abuts against the installation surface 310.

[0038] When the mounting assembly 300 is removed from the mounting base 200, the free end 3202 of the elastic arm 320 is gradually away from the avoiding slot 330 by its own elastic force as the mounting base 200 gradually moves away, until it returns to its original position.

[0039] In the embodiment, the elastic arm 320 is integrally formed with the shell 3402. The integrally formed design not only simplifies the installation steps but also improves the compactness and aesthetics of the overall structure, and can reduce the structural weakness caused by the gap or poor joint between the elastic arm 320 and the shell 3402, thereby improving the overall strength and stability of the mounting assembly 300.

[0040] In other embodiments, the elastic arm 320 and the shell 3402 can also be integrally formed. For example, the elastic arm 320 and the shell 3402 can be connected by screws, buckles, welding, etc.

[0041] The mounting assembly 300 includes a buckle assembly 340. The buckle assembly 340 is arranged in the shell 3402 and at least partially exposed to the shell 3402, configured to buckle the shell 400 to the mounting base 200. The mounting surface 310 is the mounting surface 310 arranged on the shell 3402 of the buckle assembly 340. The buckle assembly 340 firmly fixes the shell 400 on the mounting base 200 through its unique buckling structure, further enhancing the stability and safety of the installation.

[0042] Specifically, please refer to FIG. 7, the buckle assembly 340 includes a pressing piece 3401, a shell 3402, a buckle plate 3403 and two buckling pieces 3404. The pressing piece 3401 includes a pressing plate 3411 and a push rod assembly 3412, and the plane on which the pressing plate 3411 is located is defined as the first plane. The push rod assembly 3412 is connected with the pressing plate 3411 and extends along a first direction substantially perpendicular to the first plane. The shell 3402 and the buckle plate 3403 are buckled together and form a receiving cavity (not shown), and the receiving cavity is provided with a reset spring 3405. The two ends of the reset spring 3405 are respectively in abutment with the push rod assembly 3412 and the buckle plate 3403, and the push rod assembly 3412 is elastically resettable arranged in the receiving cavity. The shell 3402 is provided with a bayonet 3421 on both sides of the extension direction of the first direction. The push rod assembly 3412 includes an "eight" shaped sliding groove 3413, and the buckling piece 3404 includes a sliding column 3441. The sliding column 3441 of the buckling piece 3404 slides in the eight-shaped sliding groove 3413. The pressing piece 3401 moves relative to the shell 3402 along the first direction or the direction opposite to the first direction, and drives the two buckling pieces 3404 to slide into or out of the bayonet 3421 through the linkage of the sliding column 3441 and the eight-shaped sliding groove 3413.

[0043] When the buckle assembly 340 is installed on the installation base 200, the pressing plate 3411 is pressed until the buckle part 3442 of the clamping piece 3404 is aligned with the installation base 200, the pressing plate 3411 is released, and the reset spring 3405 drives the push rod assembly 3412 to move in the direction opposite to the first direction under the action of its own elastic force, drives the slide columns 3441 of the two clamping pieces 3404 to move in the second direction opposite to each other in the splayed slide groove 3413, so that the clamping pieces 3404 are expanded, so that the buckle part 3442 of the clamping piece 3404 is clamped with the installation base 200, and the buckle assembly 340 is fixed on the installation base 200.

[0044] When the buckle assembly 340 is removed from the installation base 200, the pressing plate 3411 is pressed, the reset spring 3405 is compressed, the push rod assembly 3412 moves along the first direction relative to the shell 3402, drives the slide columns 3441 of the two clamping pieces 3404 to move in the second direction towards each other in the splayed slide groove 3413, so that the buckle part 3442 of the clamping piece 3404 is retracted, thereby disengaging from the installation base 200.

[0045] The installation of the buckle assembly 340 and the shell 3402 is also mutual. When the buckle assembly 340 is clamped in place with the installation base 200, the elastic arm 320 is elastically deformed by the reaction force of the installation base 200. When the linear lamp 100 is applied to a facade, the presence of the elastic arm 320 can increase the friction between the installation assembly 300 and the installation base 200. At the same time, the force of the elastic arm 320 on the installation base 200 is opposite to the force of the buckle part 3442 on the installation base 200, so that the installation assembly 300 and the installation base 200 are clamped more tightly, effectively preventing the linear lamp 100 from sliding on the track.

[0046] Referring to FIG. 2, the linear lamp 100 includes a connecting part 500. The connecting part 500 connects the installation assembly 300 and the lighting assembly 700, realizing the assembly of the overall structure.

[0047] The linear lamp 100 further includes a turning assembly 600, and the connecting part 500 is rotationally connected with the lighting assembly 700 through the turning assembly 600, and is configured to enable the lighting assembly 700 to rotate relative to the installation assembly 300 in at least two degrees of freedom, so that the user can easily adjust the lighting angle and position according to actual needs, realizing a more personalized lighting effect.

[0048] Specifically, the turning assembly 600 includes a first turning mechanism 610 and a second turning mechanism 620. The first turning mechanism 610 includes a first mounting seat 6101 and a first turning shaft 6102 arranged along a first direction on the first mounting seat 6101. The first mounting seat 6101 is rotationally connected with the shell 400.

[0049] The second turning mechanism 620 comprises a second mounting base 6201 and a second turning shaft 6202 arranged on the second mounting base 6201 and in the second direction. The first turning shaft 6102 connects the first mounting base 6101 and the second mounting base 6201, and the second turning shaft 6202 is rotationally connected with the lighting assembly 700.

[0050] The first direction and the second direction intersect with each other to allow the lighting assembly 700 to be adjusted in a manner capable of moving in at least two different degrees of freedom.

[0051] The connecting part 500 is arranged in the housing 400 and fixedly connected with the housing 400. The first mounting base 6101 extends into the housing 400 and rotationally connected with the connecting part 500, thereby driving the lighting assembly 700 to rotate around the first turning shaft 6102 relative to the mounting assembly 300. The lighting assembly 700 comprises a lighting housing 710 and a light source assembly 420 arranged in the lighting housing 710. The lighting housing 710 comprises a rotating part (not shown) rotationally connected with the second turning shaft 6202 and a clamping groove (not shown) arranged between the two rotating parts. The second mounting base 6201 is arranged in the clamping groove. The lighting housing 710 is rotated around the second turning shaft 6202 through the rotating part. Through the cooperation between the turning assemblies 600, the direction and angle of the light are easily adjusted to meet the diversified lighting needs.

[0052] In summary, the linear lamp 100 of the embodiment of the present application is provided with the elastic arm 320 on the mounting surface 310, and the elastic arm 320 is in interference abutment with the mounting base 200, so that the mounting assembly 300 can significantly increase the friction between the linear lamp 100 and the vertical rail, and form a reaction force with the buckle part 3442 on the mounting assembly 300, thereby effectively preventing the linear lamp 100 from sliding under the action of external factors such as gravity, vibration or wind force, and ensuring the stability of the position of the linear lamp 100.

[0053] The above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.
