Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular to a power box assembly, a track light provided with the power box assembly, and a lighting system provided with the track light. Background Art

[0002] In the existing power box assembly of track lights, the connecting rod is mostly assembled on the box body through nuts, anti-skid gaskets and other accessories. Figure 1 As shown, the first end of the connecting rod 91 is provided with a limiting portion 911 and a stud portion 912, and the bottom of the box body 92 is provided with a connecting through hole 921; when the connecting rod 91 and the box body 92 are assembled, the stud portion 912 is inserted into the connecting through hole 921 from the bottom of the box body 92, and then an anti-slip gasket and a nut 93 are sleeved on the stud portion 912 extending into the inside of the box body 92, and the nut 93 is screwed to make the limiting portion 911 of the connecting rod 91 abut against the bottom of the box body 92, and the anti-slip gasket abuts between the inside of the box body 92 and the nut 93, thereby fixing the connecting rod 91 on the box body 92; however, the existing assembly method between the connecting rod 91 and the box body 92 has the following disadvantages: First, too many accessories are required for assembling the connecting rod 91 and the box body 92, resulting in complicated assembly steps, low assembly efficiency, and high cost.

[0003] Second, when the nut 93 is tightened too much, it will make it difficult for the connecting rod 91 to rotate relative to the box body 92; when it is loosened too much, it will cause the connecting rod 91 to move in its own axial direction relative to the box body 92; and even if an anti-slip gasket is provided, as the number of times the circumferential illumination angle of the lamp head assembly of the track light is adjusted by the connecting rod 91 increases, the nut 93 will inevitably become looser. Once the nut 93 is loose, the entire track light needs to be removed from the guide rail and the upper cover of the power box assembly needs to be disassembled before the nut 93 can be tightened. The handling process is cumbersome and inconvenient.

[0004] Third, since the stud portion 912 of the connecting rod 91 is inserted into the connecting through hole 921 from the bottom of the box body 92 and is supported and hoisted by the nut 93, the box body 92 does not exert any substantial support or limiting effect on the connecting rod 91. The lamp holder assembly is heavy, and in order to ensure the installation of other components in the box body 92, the length of the stud portion 912 cannot be too long, so that the connectable length of the nut 93 and the stud portion 912 is short, which increases the risk of the nut 93 loosening and separating from the stud portion 912. As a result, when the nut 93 becomes loose, there is a risk that the lamp holder assembly may easily cause the connecting rod 91 to separate from the box body 92 and fall, thereby affecting the safety of use and personal safety. Summary of the invention

[0005] In order to solve the above problems, the main purpose of the present invention is to provide a power box assembly with low production cost, strong rotation stability and high safety.

[0006] Another object of the present invention is to provide a track light provided with the above-mentioned power box assembly.

[0007] Another object of the present invention is to provide a lighting system provided with the above-mentioned track light.

[0008] In order to achieve the main purpose of the present invention, the present invention provides a power box assembly, including a connecting rod and a box body, the box body having an accommodating cavity, wherein the bottom of the accommodating cavity protrudes toward the bottom of the box body to form a sunken boss, the bottom wall of the sunken boss is provided with a connecting through hole, the periphery of the connecting through hole is provided with an eaves portion, and more than two elastic clips are provided in the sunken boss, the more than two elastic clips are distributed around the connecting through hole, and a clamping position is formed between the elastic clips and the eaves portion, the connecting rod has a rotating column portion and a rod portion, the first end of the rod portion is connected to the bottom of the rotating column portion, the rotating column portion is rotatably installed around its own axis in the clamping position, and the rod portion passes through the connecting through hole.

[0009] As can be seen from the above, the sunken boss on the box body is used to accommodate the rotating column part and provide substantial support for the rotating column part, so that even if the lamp holder assembly installed on the connecting rod is heavy, the connection structure between the box body and the connecting rod can effectively prevent the connecting rod and the lamp holder assembly from detaching from the box body, thereby preventing the connecting rod and the lamp holder assembly from falling, thereby improving the safety of the power box assembly and the track light provided with the power box assembly; in addition, the box body and the connecting rod are connected by a snap-fit ​​structure, which greatly reduces the number of accessories required for assembling the box body and the connecting rod, thereby simplifying the assembly between the two, improving the assembly efficiency, and reducing the production cost. At the same time, the snap-fit ​​connection between the two will neither restrict the rotation of the connecting rod relative to the box body, nor avoid unreasonable looseness of the connection between the two; furthermore, forming the elastic snap on the box body not only helps to better simplify the structure of the connecting rod and the box body, but also ensures that the box body can provide substantial support for the connecting rod.

[0010] A preferred solution is that the elastic buckle has a buckle portion, which is buckled on the top of the rotating column portion; the connecting column portion has an annular groove on its circumference, and the elastic buckle is formed with a first protrusion at the annular groove, the first protrusion is snap-connected with the annular groove, and the first protrusion is in the shape of an arc strip, hemispherical or spherical crown, or the connecting column portion has an annular protrusion on its circumference, and the elastic buckle is formed with an arc groove on the annular protrusion, and the annular protrusion is snap-connected with the arc groove; the busbar of the first protrusion in the shape of an arc strip, the busbar of the annular groove, the busbar of the annular protrusion and the busbar of the arc groove are all in the shape of a circular arc.

[0011] As can be seen from the above, this design is conducive to further preventing unreasonable loosening of the connection between the box body and the connecting rod. At the same time, with the cooperation of the above-mentioned structure, it can increase the damping effect when the connecting rod rotates relative to the box body, so as to better prevent the connecting rod from rotating relative to the box body after the angle adjustment is completed, thereby ensuring the accuracy and stability of the adjustment angle of the connecting rod and the lamp holder assembly thereon.

[0012] Another preferred solution is that a first limiting portion is formed on a surface of the eave portion facing the accommodating cavity, and a second limiting portion is formed on the bottom of the connecting column portion, and the second limiting portion can be rotated to be adjacent to the first limiting portion. As can be seen from the above, this design can limit the rotation angle of the connecting rod relative to the box body to prevent the cable passing through the connecting rod and connected to the lamp head assembly from being damaged due to excessive twisting, thereby protecting the cable.

[0013] Another preferred solution is that a plurality of engaging grooves are formed on the surface of the eaves facing the accommodating cavity, and the plurality of engaging grooves are distributed along the circumference of the connecting through hole; a spring plunger is provided at the bottom of the connecting column, and the positioning bead of the spring plunger can engage with any of the engaging grooves, or a second protrusion is formed at the bottom of the connecting column, and the second protrusion is hemispherical or spherical, and the second protrusion can engage with any of the engaging grooves.

[0014] It can be seen from the above that this design can not only appropriately increase the damping feeling when the connecting rod rotates relative to the box body, but also because the positioning bead or the second protrusion of the spring plunger will make a "ticking" sound when passing over the currently mating engaging groove, so as to enhance the user's adjustment feel and auditory experience.

[0015] Another preferred solution is that the connecting rod further has a frustum, which is connected between the rotating column portion and the first end of the rod portion, and is located in the connecting through hole; the peripheral wall of the frustum is gap-matched with the inner hole wall of the connecting through hole.

[0016] As can be seen from the above, this design can improve the stability of the rotation of the connecting rod relative to the box body, and is conducive to optimizing the force of the elastic buckle and slowing down the fatigue rate of the elastic buckle.

[0017] Another preferred solution is that a wiring channel is formed in the connecting rod, and the wiring channel runs through the connecting rod; and a stopper is formed at the second end of the rod.

[0018] As can be seen from the above, the wiring channel is used for routing the cables connecting the power module in the box body and the light source in the lamp head assembly connected to the connecting rod, and then hiding the cables in the power box assembly to enhance the aesthetics of the track light equipped with the power box assembly.

[0019] A further solution is that the power box assembly also includes an upper cover, which covers the opening of the accommodating chamber; one of the upper cover and the wall of the accommodating chamber is provided with a snap portion, and the other is provided with a slot, the snap portion is snap-connected with the slot, and / or a connecting column is provided in the accommodating chamber, the upper cover has a mounting through hole, and the power box assembly also includes a bolt, which passes through the mounting through hole and is connected to the connecting column.

[0020] As can be seen from the above, the upper cover is used for connecting with the guide rail, and at the same time, the upper cover can also prevent the power module in the box body from being contaminated by dust; and the use of a snap-fit ​​structure and / or a threaded connection structure to connect the upper cover and the box body can ensure the firmness and reliability of the connection between the two, and also make the disassembly and assembly of the two relatively simple.

[0021] A further solution is that the upper cover has an insertion portion and a cover portion, and the cover portion is connected to the box body; the power box assembly also includes a rotating wrench, the rotating wrench is rotatably connected to the upper cover, and the rotating wrench is provided with a conductive sheet group, which can extend out of the insertion portion; the rotating wrench and the connecting through hole are both located at one end of the box body, and the box body is provided with an avoidance opening at the rotating wrench, and the wrench portion of the rotating wrench extends out of the box body through the avoidance opening.

[0022] As can be seen from the above, the insertion portion of the upper cover is used to be inserted into the guide rail to cooperate with the guide rail, and the wrench is turned to lock the power box assembly to the guide rail or allow the power box assembly to be removed from the guide rail. At the same time, turning the wrench is also used to establish an electrical connection between the power box assembly and the guide rail or to release the electrical connection between the power box assembly and the guide rail.

[0023] In order to achieve another object of the present invention, the present invention provides a track light, including a lamp holder assembly, characterized in that it also includes the above-mentioned power box assembly, and the lamp holder assembly is rotatably connected to the second end of the rod.

[0024] As can be seen from the above, the track light provided with the above-mentioned power box assembly is simpler and more convenient to assemble, has lower production costs and higher safety.

[0025] In order to achieve another object of the present invention, the present invention provides a lighting system, including a guide rail, which also includes the above-mentioned guide rail light, and a power box assembly is installed on the guide rail.

[0026] As can be seen from the above, by providing the above-mentioned track lights, the lighting system has lower use costs, more convenient lighting angle adjustment, and higher lighting angle stability and safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Power supply box assembly embodiment Refer to 2 and Figure 3 The power box assembly 100 includes a box body 1, a connecting rod 2, an upper cover 3, a wrench and a bolt 5.

[0036] Combination Figure 4 The box body 1 has a receiving cavity 11, wherein the bottom of the receiving cavity 11 protrudes outward from the box body 1 to form a sinking boss 12, so that the sinking boss 12 is connected with the receiving cavity 11; preferably, the sinking boss 12 is located at the first end of the receiving cavity 11. The bottom wall of the sinking boss 12 is provided with a connecting through hole 121, which passes through the bottom wall of the sinking boss 12, and the periphery of the connecting through hole 121 has a ring of flanges 122.

[0037] More than two elastic buckles 13 are formed in the sunken boss 12, and the elastic buckles 13 extend from the accommodating cavity 11 under the eaves 122. Preferably, the number of the elastic buckles 13 is between three and five, so that the cooperation between the elastic buckles 13 can effectively clamp and limit the connecting rod 2, and the elastic buckles 13 can have the required elastic deformation capacity, which is also conducive to simplifying the structure of the box body 1 and reducing the production difficulty and production cost of the box body 1. For example, in this embodiment, the number of the elastic buckles 13 is four. In addition, the protruding end of the elastic buckle 13 has a buckle 131, and a clamping position is formed between the buckle 131 of each elastic buckle 13 and the eaves 122.

[0038] Combination Figures 5 to 7The connecting rod 2 has a rotating column 21, a rod and a truncated cone, wherein the truncated cone is connected between the bottom of the rotating column 21 and the first end of the rod, and the rotating column 21, the rod and the truncated cone are integrally formed. When the connecting rod 2 is assembled with the box body 1, the connecting rod 2 is inserted from the accommodating cavity 11 into the connecting through hole 121 of the sinking boss 12 until the rotating column 21 is clamped and fixed in the clamping position (that is, the bottom of the rotating column 21 is adjacent to the eaves 122, and the buckle 131 of the elastic buckle 13 is buckled on the top of the rotating column 21), the truncated cone is inserted into the connecting through hole 121, and the rod passes through the connecting through hole 121 and extends out of the box body 1, so that the rotating column 21 can rotate relative to the box body 1 around its own axis. Among them, the peripheral wall of the cone and the inner wall of the connecting through hole 121 are preferably clearance-fitted; the design of the cone is conducive to improving the stability of the rotation of the connecting rod 2 relative to the box body 1, and is conducive to optimizing the force on the elastic buckle 13 (it can further weaken the impact on the elastic buckle 13 caused by the uneven force between the elastic buckles 13 caused by the overturning tendency of the connecting rod 2 affected by the weight of the lamp holder assembly), and slowing down the fatigue rate of the elastic buckle 13.

[0039] Through the above-mentioned design of the matching structure between the box body 1 and the connecting rod 2, the power box assembly 100 has the following advantages: First, compared with the connecting structure of the existing power box assembly in which the connecting rod is inserted into the box body from the bottom through hole of the box body, the power box assembly 100 provided by the present invention installs the connecting rod 2 inside the accommodating cavity 11 of the box body 1 when assembling the box body 1 and the connecting rod 2 (that is, the connecting rod 2 is installed from the top of the box body 1 to the bottom of the box body 1), so that the sunken boss 12 on the box body 1 can accommodate the rotating column 21 of the connecting rod 2 while substantially supporting the rotating column 21 through the eaves 122. Therefore, even if the lamp holder assembly installed on the connecting rod 2 is heavy, the support and limitation of the eaves 122 can effectively prevent the connecting rod 2 and the lamp holder assembly from detaching from the box body 1, thereby preventing the connecting rod 2 and the lamp holder assembly from falling off, thereby improving the safety of the power box assembly 100 and the track lamp provided with the power box assembly 100, and also greatly improving the carrying capacity of the power box assembly 100, so that the power box can be adapted to a wider range of lamp holder assemblies.

[0040] Second, the elastic buckle 13 is formed on the box body 1 to better simplify the structure of the connecting rod 2 and the box body 1, avoiding the need to set a complex buckle structure on both the box body 1 and the connecting rod 2, making the structure of the connecting rod 2 more simplified, thereby reducing the production cost of the connecting rod 2 and the complexity of the production mold.

[0041] Thirdly, since the elastic buckle 13 is formed on the box body 1, it also ensures that the box body 1 can substantially support the connecting rod 2; furthermore, since the weight of the connecting rod 2 and the lamp holder assembly installed thereon is borne and supported by the eaves 122, the elastic buckle 13 cooperates with its fixing and limiting functions, so the material properties and structural strength requirements of the elastic buckle 13 are low, which is also conducive to reducing production costs and production difficulties.

[0042] Fourth, the box body 1 and the connecting rod 2 are connected by a snap-fit ​​structure, which greatly reduces the number of accessories required for assembling the box body 1 and the connecting rod 2, thereby simplifying the assembly between the two, improving the assembly efficiency, and reducing the production cost. At the same time, the snap-fit ​​connection between the two will neither restrict the rotation of the connecting rod 2 relative to the box body 1, nor prevent unreasonable looseness of the connection between the two.

[0043] Fifth, since there is no need to set a limiting structure for a matching nut on the connecting rod 2 as in the prior art, the overall appearance of the power box is made more concise, coordinated and beautiful.

[0044] Preferably, the connecting column 112 of the connecting rod 2 has an annular groove 211 in the axial direction, and at least a portion of the elastic buckles 13 are formed with a first protrusion 132 at the annular groove 211; preferably, each elastic buckle 13 is formed with a first protrusion 132 at the annular groove 211. When the box body 1 and the connecting rod 2 are assembled, the first protrusion 132 is engaged in the annular groove 211. The first protrusion 132 is preferably in the shape of an arc strip (see Figure 4 ), hemispherical or spherical crown; wherein, the generatrix of the arc-shaped first protrusion 132 and the generatrix of the annular groove 211 are both in the shape of an arc. This design is conducive to further preventing unreasonable looseness of the connection between the box body 1 and the connecting rod 2; at the same time, with the cooperation of the above structure, the damping effect when the connecting rod 2 rotates relative to the box body 1 can be increased, so as to better prevent the connecting rod 2 from rotating relative to the box body 1 after the angle adjustment is completed, thereby ensuring the accuracy and stability of the adjustment angle of the connecting rod 2 and the lamp head assembly thereon. Of course, as another optional scheme, in other embodiments, the above structure (annular groove 211, first protrusion 132) can also be changed as follows: an annular protrusion is formed on the circumference of the connecting column 112, and an arc groove that cooperates with the annular protrusion is formed on each elastic buckle 13, so that when the box body 1 and the connecting rod 2 are assembled, the annular protrusion is clamped in the arc groove; wherein, the generatrix of the annular protrusion and the generatrix of the arc groove are both in the shape of an arc.

[0045] In addition, in order to limit the rotation angle of the connecting rod 2 relative to the box body 1, so as to prevent the cable passing through the connecting rod 2 and connected to the lamp head assembly from being damaged due to excessive twisting, a first limiting portion 123 is formed on the side of the eaves 122 facing the accommodating cavity 11, and a second limiting portion 212 is formed on the bottom of the connecting column 112 of the connecting rod 2. The second limiting portion 212 can rotate with the connecting rod 2 until it is adjacent to the first limiting portion 123, thereby limiting the rotation of the connecting rod 2 relative to the box body 1; preferably, the rotation angle between the connecting rod 2 and the box body 1 is between 0° and 355°, so as to maximize the rotatable angle of the connecting rod 2 as much as possible, thereby maximizing the lighting range of the lamp head assembly connected to the connecting rod 2 as much as possible. It can be seen that the cables can be protected by the matching design of the first limiting portion 123 and the second limiting portion 212.

[0046] Furthermore, a plurality of engaging grooves 124 are formed on the side of the eaves 122 facing the accommodating cavity 11, and the plurality of engaging grooves 124 are distributed along the circumference of the connecting through hole 121, and two adjacent engaging grooves 124 are preferably closely adjacent to each other; matchingly, as in the present embodiment, a spring plunger 213 is provided at the bottom of the connecting column 112, and the positioning column of the spring plunger 213 is arranged toward the engaging groove 124, so that the positioning bead 2131 of the spring plunger 213 can engage with any engaging groove 124. This design can not only appropriately increase the damping feeling when the connecting rod 2 rotates relative to the box body 1, but also, when the positioning bead 2131 of the spring plunger 213 passes over the currently matched engaging groove 124 and switches to engage with the next engaging groove 124, a matching sound similar to "ticking" will be emitted, so as to enhance the user's adjustment feel and hearing experience. It should be noted that, as another optional solution, in other embodiments, the spring plunger 213 can be replaced by forming a second protrusion at the bottom of the connecting column 112, that is, in this solution, the second protrusion can be engaged with any engaging groove 124; wherein the second protrusion is preferably hemispherical or spherical.

[0047] Furthermore, a wiring channel is formed in the connecting rod 2, and the wiring channel runs through the connecting rod 2. The wiring channel is used to route the cables connected between the power module in the box body 1 and the light source in the lamp head assembly connected to the connecting rod 2, and then the cables are hidden in the power box assembly 100 to improve the aesthetics of the track light equipped with the power box assembly 100. In addition, the second end of the rod portion of the connecting rod 2 is preferably formed with a stopper, which is used to cooperate with the lamp head assembly and can limit the lamp head assembly in a vertical position, thereby ensuring the lighting effect when the lamp head assembly is vertically illuminated.

[0048] The upper cover 3 covers the opening of the accommodating cavity 11 of the box body 1 to prevent the power module disposed in the box body 1 from being polluted by dust; wherein the opening of the accommodating cavity 11 is formed at the top of the box body 1. The upper cover 3 has an inserting portion 31 and a cover portion 32, the cover portion 32 is connected to the box body 1, the inserting portion 31 is used for the guide rail matching connection, and the cover portion 32 covers the opening of the accommodating cavity 11.

[0049] One of the cover portion 32 of the upper cover 3 and the wall portion of the accommodating chamber 11 is provided with a snap portion 111, and the other is provided with a slot 322. For example, in the present embodiment, the cover portion 32 is formed with a slot 322, and the wall portion of the accommodating chamber 11 is formed with a snap portion 111. When the upper cover 3 is assembled with the box body 1, the snap portion 111 is engaged in the slot 322; and / or, a connecting column 112 is provided in the accommodating chamber 11, and the upper cover 3 has a mounting through hole 321. The power box assembly 100 also includes a bolt 5. When the upper cover 3 is assembled with the box body 1, the bolt 5 passes through the mounting through hole 321 and is connected to the connecting column 112. In this embodiment, the upper cover 3 is formed with a card slot 322 and a mounting through hole 321, and the box body 1 is formed with a buckle portion 111 and a connecting column 112; the upper cover 3 and the box body 1 are connected by a composite connection structure of a snap-fit ​​structure and a threaded connection structure, which can ensure the firmness and reliability of the connection between the two, and also make the disassembly and assembly of the two relatively simple.

[0050] The rotating wrench 4 is rotatably connected to the upper cover 3, and a conductive sheet group 42 is provided on the rotating wrench 4, so that the conductive sheet group 42 can rotate with the rotating wrench 4 to extend out of the insertion portion 31, and then be electrically connected to the corresponding conductive copper strip in the guide rail, so that the guide rail supplies power to the power box assembly 100. Preferably, the rotating wrench 4 and the connecting through hole 121 are both located at one end of the box body 1. This design can better optimize the internal space of the box body 1 to ensure that the power module can be installed in the box body 1, and at the same time it is beneficial to reduce the volume of the power box assembly 100 and save production costs.

[0051] In addition, the box body 1 is provided with an avoidance opening 113 at the rotating wrench 4, and the wrench portion 41 of the rotating wrench 4 extends out of the box body 1 through the avoidance opening 113; further, two limit blocks 1131 are provided in the avoidance opening 113, and the two limit blocks 1131 are respectively used to limit the rotating wrench 4 to an unlocked position and a locked position; when the rotating wrench 4 is in the unlocked position, the conductive sheet group 42 thereon is disconnected from the electrical connection with the conductive copper bar in the guide rail, so that the power box assembly 100 can be removed from the guide rail; when the rotating wrench 4 is in the locked position, the conductive sheet group 42 thereon extends to the insertion portion 31 of the upper cover 3 and is electrically connected to the conductive copper bar in the guide rail, so that the guide rail supplies power to the power box assembly 100.

[0052] Furthermore, an elastic pressing buckle 311 is provided on the insertion portion 31 at the end away from the rotating wrench 4. The fixed end of the elastic pressing buckle 311 is located at the top of the insertion portion 31. The free end of the elastic pressing buckle 311 is arranged close to the cover portion 32. The claw of the elastic pressing buckle 311 is used for matching connection with the guide rail. The elastic pressing buckle 311 is used to improve the firmness and reliability of the connection between the power box assembly 100 and the guide rail. When the power box assembly 100 is connected to the guide rail, the claw of the elastic pressing buckle 311 is connected to the matching card slot on the guide rail. When the power box assembly 100 needs to be disassembled from the guide rail, after the rotating wrench 4 is rotated to the unlocking position, the free end of the elastic pressing buckle 311 is pressed to disengage the claw from the matching card slot of the guide rail, and the power box assembly 100 can be removed from the guide rail.

[0053] In summary, it can be seen that through the design of the power box assembly 100, the power box assembly 100 has the advantages of low production cost, strong rotation stability and high safety.

[0054] Track light embodiment The track light includes a lamp holder assembly and the power box assembly described in the above-mentioned power box assembly embodiment. The lamp body of the lamp holder assembly is rotatably connected to the second end of the rod of the power box assembly. When the lamp holder assembly is in a vertical irradiation position, the stopper at the second end of the rod can be adjacent to the lamp body to position the lamp holder assembly in the vertical irradiation position. The power module provided in the power box assembly is electrically connected to the light source in the lamp holder assembly, and the straight cable between the power module and the light source passes through the wiring channel in the connecting rod to realize hidden wiring of the cable, thereby protecting the cable and making the appearance of the track light more neat and streamlined, thereby enhancing the overall aesthetics of the track light. By providing the above-mentioned power box assembly, the assembly of the track light is simpler and more convenient, the production cost is lower and the safety is higher.
