Description

Technical Field

[0001] This utility model relates to the field of LED lighting fixtures, and in particular to a track box and a track floodlight. Background Technology

[0002] Track lights typically draw power from the side of the track box. Long conductors are installed on both sides of the track groove, and elastic contacts corresponding to the conductors are installed on both sides of the track box. After the track box is installed into the track groove, the elastic contacts make contact with the conductors to conduct electricity, and the long conductors allow the track light to draw power at different sliding positions.

[0003] However, in some track mechanisms, long conductors cannot be continuously installed in the track groove, and when long conductors are placed on the side wall of the track groove, they are too close to the opening of the track groove, posing a safety hazard. Therefore, in some track mechanisms, long conductors are currently placed at the bottom of the track groove. This requires the elastic contacts to protrude from the upper surface of the track box. The elastic contacts are generally formed by bending metal plates and need to be connected to the circuit board. However, the circuit boards of LED lamps usually have large current / voltage processing components, resulting in a large distance between the circuit board and the upper surface of the track box. The metal plates have a large extension height, which makes their elastic performance poor, the elastic contact force with the long conductor is small, and the power supply stability is poor.

[0036] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0037] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0038] like Figures 1 to 6As shown, the track box according to an embodiment of the present invention includes a box body 100, a circuit board 200, and an upper power connection assembly. The circuit board 200 is disposed inside the box body 100. The upper power connection assembly includes at least two upper power connection springs 300. Each upper power connection spring 300 includes a lower connecting portion 310, a spring arm portion 320, and an upper contact portion 330 connected sequentially from bottom to top. The lower connecting portion 310 is connected to the circuit board 200, and the upper contact portion 330 can protrude from the upper end surface of the box body 100 through the first notch 121. The upper contact portion 330 has an inverted V-shaped structure. The two downwardly extending ends of the upper contact portion 330 are the connecting end 331 and the suspended end 332, respectively. The connecting end 331 is connected to the elastic arm portion 320. The box body 100 is provided with a guide surface 101. When the upper contact portion 330 is pressed down, the suspended end 332 can press down against the guide surface 101. The guide surface 101 can guide the suspended end 332 to move away from the connecting end 331 to form elastic support for the upper contact portion 330.

[0039] When the track box is inserted into the track groove, the upper contact part 330 is pressed, and the guide surface 101 causes the upper contact part 330 to undergo elastic deformation. The elastic arm part 320 forms a large elastic support force on the upper contact part 330, so that the upper contact part 330 forms a stable electrical connection with the conductor in the track groove, thereby improving reliability.

[0040] In some embodiments of this utility model, the upper contact spring 300 is made of bent metal sheet, the elastic arm 320 is generally formed by bent metal plate, and the upper contact part 330 has an inverted V-shaped structure. When the suspended end 332 is guided to move away from the connection end 331, the V-angle of the upper contact part 330 of the inverted V-shaped structure becomes larger, thereby generating a reset elastic force, so that the upper end of the upper contact part 330 has an upward tendency, thereby having a better contact effect with the conductor in the track groove, and the reliability of the electrical connection is high.

[0041] In some embodiments of this utility model, the guide surface 101 is a concave arc-shaped surface, so as to gradually increase the variation range of the V-shaped angle of the upper contact portion 330 of the inverted V-shaped structure and increase the elastic force.

[0042] Specifically, such as Figure 4 , Figure 5As shown, the guide surface 101 of the concave arc structure is located below the suspended end 332 and extends in a direction away from the connecting end 331. When the suspended end 332 just contacts the guide surface 101 of the concave arc structure, the change range of the V-angle of the upper contact portion 330 of the inverted V-shaped structure is not large. As the upper contact portion 330 continues to be pressed down, the suspended end 332 moves in a direction away from the connecting end 331 along the concave arc surface, so that the change range of the V-angle of the upper contact portion 330 of the inverted V-shaped structure gradually increases (that is, the change range of the V-angle increases per unit distance the upper contact portion 330 is pressed down), thus generating a large elastic force.

[0043] It is understood that in some embodiments of this utility model, the guide surface 101 may also be an inclined surface adapted to the inner side of the suspended end 332. When the suspended end 332 slides down the inclined surface, the V-angle change range of the upper contact portion 330 of the inverted V-shaped structure remains basically unchanged, but it can still generate a reaction elastic force on the upper contact portion 330 from the suspended end 332, thereby improving the elastic support effect on the upper contact portion 330.

[0044] like Figure 4 , Figure 5 As shown, in some embodiments of this utility model, the end of the suspended end 332 is provided with a rounded corner structure corresponding to the guide surface 101 to reduce the resistance to the movement of the suspended end 332.

[0045] like Figure 4 , Figure 5 , Figure 6 As shown, in some embodiments of this utility model, the elastic arm 320 is a plate extending obliquely downward, and the elastic arm 320 and the lower connecting part 310 form a V-shaped structure with a side opening to elastically support the upper contact part 330.

[0046] It is understood that in some embodiments of this utility model, the elastic arm 320 may also be other bent plate structures, such as Z-shaped, S-shaped, etc., and may also provide elastic support for the upper contact portion 330.

[0047] In some embodiments of this utility model, the upper connecting spring 300 is a metal spring, which is made by bending metal (such as copper).

[0048] like Figure 2 , Figure 3 As shown, in some embodiments of this utility model, the box body 100 includes a bottom box 110 and a top cover 120. The bottom box 110 is open upwards, and the circuit board 200 is disposed inside the bottom box 110. The top cover 120 is mounted on the upper end of the bottom box 110 and is provided with a first notch 121 that allows the upper contact portion 330 to extend upwards. The side wall of the bottom box 110 is provided with a protruding ridge 111, and the guide surface 101 is disposed at the upper end of the ridge 111.

[0049] like Figure 2 , Figure 3 , Figure 7 As shown, in some embodiments of this utility model, the track box further includes a side-connecting power assembly, which includes two side-connecting power springs 400. The side-connecting power springs 400 are elongated structures corresponding to the length direction of the box body 100. The side-connecting power springs 400 include a side connecting part 410 and a side contact part 420. The side connecting part 410 is connected to the circuit board 200, and the side contact part 420 is suspended. The side of the box body 100 is provided with a second notch 122 that allows the side contact part 420 to extend. The side contact part 420 can contact the conductor at the groove wall in the track groove to realize lateral power supply of the track box.

[0050] Specifically, the track box can be configured with an upper power connection component and a side power connection component to adapt to different track components. In specific applications, the first notch 121 or the second notch 122 can be blocked as needed to meet the actual application of the track box (upper power connection or side power connection).

[0051] In some embodiments of this utility model, a detachable baffle (not shown in the figure) is provided at the first notch 121 and the second notch 122 respectively. When the baffle is installed at the first notch 121 or the second notch 122, the upper contact portion 330 or the side contact portion 420 can be pressed into the box body 100 accordingly, so that the upper contact portion 330 or the side contact portion 420 is not exposed, so as to achieve the purpose of single power supply and high flexibility of use.

[0052] In some embodiments of this utility model, the baffle (not shown in the figure) is installed on the first notch 121 and the second notch 122 by a snap-fit ​​mechanism.

[0053] Of course, in the specific implementation process, the baffle can also be detachably installed on the first notch 121 and the second notch 122 through the threaded fitting mechanism. If the first notch 121 and the second notch 122 are both circular structures with internal threads, and the baffle is a corresponding circular structure with external threads, the baffle can be inserted into or screwed out of the first notch 121 and the second notch 122 to meet different power supply requirements.

[0054] In some embodiments of this utility model, two side-connected electrical springs 400 are distributed opposite to each other, and an elastic mechanism is provided between the two side contact portions 420 to improve the elastic support force of the side-connected electrical springs 400, improve the elastic resistance force between the side contact portions 420 and the conductor, and improve the stability of the electrical connection.

[0055] like Figure 2 , Figure 3 As shown, in some embodiments of this utility model, the elastic mechanism is a rubber block 430, which can achieve both elastic support and insulation.

[0056] It is understood that, in some embodiments of this utility model, the elastic mechanism may also be a plastic spring.

[0057] like Figure 2 , Figure 3 , Figure 7 As shown, in some embodiments of this utility model, the side contact portion 420 is provided with a blocking portion 440 extending away from the side connection portion 410. The blocking portion 440 is located inside the box body 100 and can abut against the inner wall of the box body 100 to prevent the side connection portion 410 from being ejected excessively and becoming ineffective.

[0058] Specifically, such as Figure 3 As shown, the elastic mechanism generates an outward elastic force on the side connecting part 410. Since the side connecting part 410 is a suspended end, if there is no blocking part 440 to block it, the side connecting part 410 will be freely ejected, and the ejection will be excessive, affecting the normal assembly of the track box. In this utility model, the extension distance of the side connecting part 410 is limited by the contact between the blocking part 440 and the inner wall of the box body 100, thereby improving reliability.

[0059] In some embodiments of this utility model, the side-connected electrical spring 400 is a metal spring, which is made by bending metal (such as copper).

[0060] Reference Figure 8 and Figure 9 According to a second aspect embodiment of the present invention, the track floodlight includes a track box according to any of the first aspects of the present invention, so that the track floodlight can be adapted to a power-generating track assembly and the electrical connection is stable and reliable.

[0061] Specifically, such as Figure 8 and Figure 9 The track floodlight includes a track box and a lamp body 900, which are connected by a clamping mechanism or a screw mechanism.

[0062] The lamp body 900 includes a lamp housing 901, a light source assembly 902, and a lens assembly 903. The lamp housing 901 is provided with an inner cavity that can accommodate the light source assembly 902 and the lens assembly 903. The lens assembly 903 is a floodlight lens, which makes the lamp body 900 illuminate evenly and with a wide illumination area.

[0063] Specifically, the lens assembly 903 includes multiple diffuser lens structures, which enable light to diffuse and overlap at multiple angles, thereby making the light more uniform and the illumination area larger.

[0064] Of course, this invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
