Technical Field

[0001] The utility model relates to the technical field of lamps, and in particular to a power supply box and a track lamp provided with the power supply box, and a lighting system provided with the track lamp. Background Art

[0002] Compared with traditional spotlights and downlights, track lights are more popular among consumers due to their flexible and changeable position settings, flexible lighting direction adjustment and wide adjustment range. Existing track lights generally include a power box, a connecting rod assembly and a lamp body unit. The connecting rod assembly is connected between the power box and the lamp body unit, so that the lamp body unit can adjust the lighting pitch angle and circumferential lighting position through the connecting rod assembly. When the setting position of the track light needs to be adjusted, it can be adjusted by adjusting the relative position of the power box and the track.

[0003] like Figure 1 As shown, it shows the power box 9 of the existing track light, and the power box 9 includes a box body 91, a cover body 92, a rotating wrench 93 and a power control module. The box body 91 has a receiving cavity, and the cover body 92 is detachably mounted on the box body 91 and covers the opening of the receiving cavity. The rotating wrench 93 is rotatably mounted on the cover body 92, and the number of the rotating wrench 93 is preferably two, one of the two rotating wrenches 93 is provided with a rotating block 931, and the rotating block 931 is used to cooperate with the guide rail, and the other of the two wrenches is provided with a conductive plug 932, and the conductive plug 932 is used to be electrically connected to the conductive sheet in the guide rail, and the conductive plug 932 also has the function of engaging and connecting with the guide rail, so as to cooperate with the rotating block 931 to clamp the power box 9 on the guide rail. The power control module is installed in the receiving cavity, and the power control module is electrically connected to the conductive plug 932, and the power control module is also used to be electrically connected to the light source in the lamp body unit to control the light source to illuminate according to the set mode. However, the existing power supply box 9 has the following disadvantages:

[0004] There is no locking structure between the rotating wrench 93 and the cover 92. Since there is a first interaction force between the rotating clamp 931 and the guide rail, the rotating wrench 93 with the rotating clamp 931 is easily affected by the first interaction force and forced to rotate, resulting in the loosening of the engagement connection between the rotating clamp 931 and the guide rail. Similarly, since there is a second interaction force between the conductive plug 932 and the guide rail and the conductive sheet therein, the rotating wrench 93 with the missile plug is easily affected by the second interaction force and forced to rotate, resulting in the loosening of the engagement connection between the conductive plug 932 and the guide rail and the conductive sheet therein, and affecting the stability of the electrical connection between the conductive plug 932 and the conductive sheet therein. In addition, when adjusting the position of the rotating wrench 93, the adjustment feel is not good, affecting the user experience. Summary of the invention

[0009] As can be seen from the above, with the cooperation of the first engaging structure and the second engaging structure, the rotating handle can be stably kept at the set corresponding gear relative to the cover body, thereby preventing the rotating wrench from being fixed relative to the cover body when not pulled by the user, ensuring the firmness and reliability of the rotating wrench after being connected to the guide rail, so that the track light equipped with the power box can be stably electrically connected to the guide rail. In addition, the design of the first engaging structure and the second engaging structure also allows the user to give the installer obvious hand feedback when the user pulls the rotating wrench, so as to enhance the installer's experience.

[0034] Track light first embodiment

[0035] Reference Figure 2 The track light 100 includes a power box 1, a connecting rod assembly 2 and a lamp body unit 3.

[0036] Combination Figure 3 The power supply box 1 includes a box body 11, a cover body 12, a rotating wrench 13 and a power supply control module 14. The box body 11 has a receiving cavity 111, and the power supply control module 14 is installed in the receiving cavity 111. The power supply control module 14 is used to be electrically connected to the light source 32 in the lamp body unit 3 to control the light source 32 to illuminate according to the set mode.

[0037] The cover 12 is detachably connected to the box body 11 , and the cover 12 covers the opening of the accommodating cavity 111 to seal the accommodating cavity 111 , preventing external dust from entering the accommodating cavity 111 and contaminating the power control module 14 , thereby protecting the power module.

[0038] The rotating wrench 13 has a rotating portion 131 and a wrench portion 132. The rotating portion 131 is rotatably mounted on the cover body 12 around its own rotation axis. The cover body 12 is provided with a first engaging structure 1211, and the rotating portion 131 is provided with a second engaging structure 1311. The first engaging structure 1211 is used to engage with the second engaging structure 1311 to limit the rotating wrench 13, thereby preventing the rotating wrench 13 from rotating relative to the cover body 12. There are more than two engaging gears between the first engaging structure 1211 and the second engaging structure 1311, so that the rotating wrench 13 can be limited at different positions relative to the cover body 12.

[0039] In this embodiment, the number of the rotating wrenches 13 is preferably two, and the two rotating wrenches 13 are respectively arranged at the two ends of the cover body 12. By setting the number of the rotating wrenches 13 to two, it is beneficial to further improve the stability and firmness when the power box 1 is connected to the guide rail, and make the disassembly and assembly between the power box 1 and the guide rail more convenient. Figure 4 As shown, a rotating block 1321 is formed on the rotating portion 131 of the first rotating wrench 13; Figure 5 As shown, a conductive plug 1313 is disposed on the rotating portion 131 of the second rotating wrench 13 .

[0040] In addition, the rotating block 1321 is preferably formed integrally with the rotating portion 131 of the first rotating wrench 13. The conductive plug 1313 includes a mounting terminal 13131, a first conductive sheet 13132, a second conductive sheet 13133 and a third conductive sheet 13134. The mounting terminal 13131 is preferably detachably mounted on the rotating portion 131 of the second rotating wrench 13. The first conductive sheet 13132, the second conductive sheet 13133 and the third conductive sheet 13134 are all mounted on the mounting terminal 13131, and the first conductive sheet 13132, the second conductive sheet 13133 and the third conductive sheet 13134 are all electrically connected to the power control module 14; wherein the first conductive sheet 13132 is used to be electrically connected to the live wire conductive sheet in the guide rail, the second conductive sheet 13133 is used to be electrically connected to the neutral wire conductive sheet in the guide rail, and the third conductive sheet 13134 is used to be electrically connected to the ground wire conductive sheet in the guide rail.

[0041] To match the number of the rotating wrenches 13, in this embodiment, the number of the first engaging structures 1211 on the cover body 12 is also two, and the two first engaging structures 1211 correspond one to one with the two rotating wrenches 13. Among them, one of the first engaging structure 1211 and the second engaging structure 1311 is a first engaging recessed position, and the other is an engaging protrusion, and the first engaging structure 1211 is integrally formed with the cover body 12, and the second engaging structure 1311 is integrally formed with the rotating wrench 13. In addition, the number of the first engaging recessed positions is preferably more than two, and the more than two first engaging recessed positions are distributed around the rotation axis, and the number of the engaging protrusion is preferably at least one, and the engaging protrusion is engaged and connected with one of the more than two first engaging recessed positions.

[0042] Preferably, there are multiple first engaging recesses, which are continuously distributed around the axis of rotation, and two adjacent first engaging recesses are adjacent; wherein, the first engaging recess is preferably a spherical crown surface 12111, the height of the spherical crown surface 12111 is less than the radius of the ball corresponding to the spherical crown surface, and the open part of the spherical crown surface has a guide surface 12112, and the guide surfaces 12112 of two adjacent first engaging recesses are adjacent. By making two adjacent first engaging recesses adjacent to each other, the adjustment feel when rotating and adjusting the rotating wrench 13 can be improved; and by designing the structure of the first engaging recess, the first engaging recess can be reliably engaged with the first engaging protrusion, and the user can more easily turn the rotating wrench 13 to switch the first engaging protrusion to engage with another first engaging recess.

[0043] For example, in this embodiment, the first engaging structure 1211 is a first engaging recess, and the number of the first engaging recess is 16, and the 16 first engaging recesses are continuously and evenly distributed around the rotation axis of the rotating part 131, and the guide surfaces 12112 of two adjacent first engaging recesses are adjacent; the second engaging structure 1311 is an engaging protrusion, and the number of the second engaging protrusions is 4, and the 4 engaging protrusions are evenly distributed around the rotation axis of the rotating part 131. It should be noted that when any engaging protrusion is engaged with any first engaging recess, the remaining engaging protrusions are all engaged with a matching first engaging recess; similarly, when any engaging protrusion is disengaged from the first engaging recess, the remaining engaging protrusions are also disengaged from the first engaging recess. Of course, in other embodiments, the first engaging structure 1211 can be an engaging protrusion, and the second engaging structure 1311 is a first engaging recess. Through the above-mentioned design of the first engaging structure 1211 and the second engaging structure 1311, the total number of parts of the power box 1 can be reduced, the difficulty of assembly can be reduced, which is conducive to improving production efficiency and saving production costs.

[0044] Preferably, a sunken recess 121 is formed on the cover body 12 to match the number of the rotating wrenches 13. In the present embodiment, the number of the sunken recesses 121 on the cover body 12 is also two, and the two sunken recesses 121 correspond one-to-one to the two rotating wrenches 13, so that a portion of a rotating wrench 13 is located in a corresponding sunken recess 121.

[0045] The sunken recess 121 is sunken from the top surface of the cover plate to the accommodating cavity 111 of the box body 11, and the first engaging structure 1211 is located in the sunken recess 121 and at the bottom surface of the sunken recess 121. Furthermore, the sunken recess 121 has a first limiting surface 1212 and a second limiting surface 1213. In the rotation direction of the rotating wrench 13, the wrench portion 132 of the rotating wrench 13 is located between the first limiting surface 1212 and the second limiting surface 1213. The first limiting surface 1212 and the second limiting surface 1213 are used to limit the maximum rotation range of the rotating wrench 13 to prevent the rotating wrench 13 from over-rotating. By setting the sunken recess 121 to accommodate the rotating wrench 13, it is helpful to reduce the height of the power box 1, thereby reducing the volume of the power box 1 and making the power box 1 more beautiful.

[0046] Furthermore, the wrench portion 132 is provided with anti-skid lines 1321, and the anti-skid lines 1321 are located outside the sunken recess 121. The anti-skid lines 1321 help the installer to better control the wrench portion 132 to rotate the rotating wrench 13, and avoid slipping when grabbing or turning the wrench portion 132.

[0047] In addition, the cover body 12 is further provided with a heat dissipation slot 122, which is in communication with the accommodating cavity 111. Since the power control module 14 generates heat during operation, the heat dissipation slot 122 is provided on the cover body 12, so that the heat generated by the power control module 14 can be evacuated through the heat dissipation slot 122, thereby ensuring the stability and reliability of the operation of the power control module 14 and extending the service life of the power control module 14.

[0048] The connecting rod assembly 2 includes a first connecting rod 21 and a second connecting rod 22; the lamp body unit 3 includes a lamp body 31, a light source 32 and a lens 33. The first end of the first connecting rod 21 is hinged to the box body 11, the second end of the first connecting rod 21 is hinged to the first end of the second connecting rod 22, and the second end of the second connecting rod 22 is hinged to the lamp body 31. The upper movable lamp body 31 can be adjusted in pitch and circumferential illumination angles through the connecting rod assembly 2. Preferably, a first wire groove 211 is provided in the first connecting rod 21, and the first wire groove 211 runs through the first connecting rod 21; a second wire groove 221 is provided in the second connecting rod 22, and the second wire groove 221 runs through the second connecting rod 22; the first wire groove 211 communicates with the accommodating cavity 111 and the second wire groove 221, and the second wire groove 221 communicates with the inside of the lamp body 31, so that the cables between the lamp body unit 3 and the power box 1 can be routed internally through the first wire groove 211 and the second wire groove 221, avoiding the cables from being exposed to the outside, which not only protects the cables, but also improves the aesthetics of the track light 100. The light source 32 and the lens 33 are installed in the lamp body 31, and the lens 33 is located at the light emitting front end of the lamp body 31 and directly between the light source 32, and the light emitting end of the light source 32 is arranged toward the lens 33, and the lens 33 can optimize the lighting effect of the light source 32.

[0049] In summary, it can be seen that the cover body 12 and the rotating wrench 13, under the cooperation of the first engaging structure 1211 and the second engaging structure 1311, can make the rotating handle stay stably at the set corresponding gear relative to the cover body 12, thereby preventing the rotating wrench 13 from remaining fixed relative to the cover body 12 when not being pulled by the user, ensuring the firmness and reliability of the rotating wrench 13 after being connected to the guide rail, so that the track light 100 equipped with the power box 1 can be stably electrically connected to the guide rail. In addition, the design of the first engaging structure 1211 and the second engaging structure 1311 also allows the user to switch between the first engaging structure 1211 and the second engaging structure 1311 when pulling the rotating wrench 13, which can give the installer obvious hand feedback when switching the engaging gear, so as to enhance the installer's experience.

[0050] Track light second embodiment

[0051] The difference between this embodiment and the first embodiment of the track light lies in the first engaging structure and the second engaging structure. Specifically, in this embodiment:

[0052] One of the first engaging structure and the second engaging structure is a second engaging recess, and the other is a spring plunger; the number of the second engaging recess is more than two, and the more than two second engaging recesses are distributed around the rotation axis; the number of the spring plunger is at least one, and the positioning piece of the spring plunger is engaged with one of the more than two second engaging recesses. In this embodiment, the design concept of the first engaging structure and the second engaging structure is the same. For example, the second engaging recess in this embodiment replaces the first engaging recess in the first embodiment of the track light, and the spring plunger replaces the engaging protrusion in the first embodiment of the track light.

[0053] Through the design of the first engaging structure and the second engaging structure, this embodiment can effectively reduce the resistance encountered during the adjustment process of the rotating wrench. On the basis of ensuring that the rotating wrench after adjustment is effectively locked, the adjustment feel of the rotating wrench is better improved, the rotating wrench can be turned more labor-savingly, and the wear rate of the cover body can be simplified, which is beneficial to extending the service life of the cover body.
