Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a telescopic adjustment unit and a ceiling light equipped with the telescopic adjustment unit. Background Technology

[0002] Currently, the mainstream ceiling lights on the market mainly include fixed ceiling lights, chandeliers, and track lights. Fixed ceiling lights are installed directly embedded in the ceiling; chandeliers are suspended from the ceiling by wires or rods; and track lights are installed on a pre-set track and can slide along the track to adjust the illumination position. However, all of these types of lights share a common drawback: their illumination height cannot be flexibly adjusted according to actual needs. To solve this problem, retractable lighting fixtures have emerged, addressing the shortcomings of traditional ceiling lights in terms of illumination height adjustment.

[0003] like Figure 1 and Figure 2 As shown, the telescopic lamp 9 includes a telescopic adjustment unit 91 and a lamp body unit 92. The telescopic adjustment unit 91 includes a guide bracket 911, a sliding seat 912, and a connecting frame 913; the guide bracket 911 is provided with a guide rail assembly, which includes multiple guide rails, each guide rail having a through groove 9111. The two side walls of the through groove 9111 are symmetrically provided with wavy protrusions, each wavy protrusion including multiple arc-shaped steps 91111 distributed along the extension direction of the through groove 9111, with a locking mechanism formed between two adjacent arc-shaped steps 91111; the sliding seat 912 is integrally formed with multiple V-shaped... The sliding seat 912 is movably disposed within the space enclosed by the guide rail assembly, with multiple elastic claws 9121 corresponding one-to-one with multiple guide rails. The elastic claws 9121 pass through through slots 9111 and engage with their corresponding guide rails. The height of the sliding seat 912 is adjusted by regulating the engagement of the two claw ends of the elastic claws with different positions on the wavy protrusions. A connecting frame 913 is mounted on the sliding seat 912. The lamp body unit 92 is connected to the connecting frame 913, allowing the height of the lamp body unit 92 to be adjusted in accordance with the changes in the sliding seat 912.

[0004] However, the aforementioned telescopic lamp 9 has the following shortcomings: First, the mating structure between the sliding seat 912 and the guide bracket 911 results in a single adjustment method, which can only achieve stepped adjustment, thus also making the adjustment feel monotonous. Second, the sliding force of the sliding seat 912 relative to the guide bracket 911 is not adjustable. When the weight of the lamp body unit 92 increases, there is a greater risk of it slipping off the track. Third, although the assembly steps between the sliding seat 912 and the guide bracket 911 are simple, the assembly of the sliding seat 912 and the guide bracket 911 is difficult, and the structure of the sliding seat 912 is relatively complex. In addition, since the elastic claw 9121 is integrally formed on the sliding seat 912, the material requirements for the sliding seat 912 are high, which increases the production difficulty of the sliding seat 912. Utility Model Content

[0005] The primary objective of this invention is to provide a telescopic adjustment unit with different adjustment methods, adjustable adjustment force, and ease of production and assembly.

[0006] The second objective of this invention is to provide a ceiling light equipped with the aforementioned telescopic adjustment unit.

[0007] To achieve the first objective of this utility model, it provides a telescopic adjustment unit, including a guide bracket and a sliding seat. The guide bracket includes a connecting ring and two or more guide rails distributed circumferentially along the connecting ring. The guide rails are provided with through grooves extending along their own extension direction. The sliding seat is movably disposed within the space enclosed by all the guide rails. The guide rails are provided with wavy protrusions on the adjacent side of the through grooves. The wavy protrusions include multiple arc-shaped steps distributed along the extension direction, and a locking position is formed between two adjacent arc-shaped steps. The telescopic adjustment unit also includes two or more sets of locking components. The locking components include spring pieces, bolts, and elastic elements. The elastic elements include a plate portion and a claw portion. The plate portion is provided with a through hole. The claw portion is bent relative to the plate portion. The bolt passes through the elastic element, the through hole, and the through groove in sequence and is connected to the sliding seat. The elastic element forces the spring piece to move toward the wavy protrusion. The plate portion contacts the wavy protrusion, and / or the claw portion engages with any locking position.

[0008] As can be seen from the above, by designing and configuring locking components at the positions of the wavy protrusions, the telescopic adjustment unit can have different adjustment methods, such as stepless adjustment and stepped adjustment. In addition, based on the cooperation of bolts and elastic elements, the force of the sliding seat movement can be adjusted, and it can be ensured that the sliding seat is reliably selected at the desired adjustment position without being affected by the weight of the ceiling light unit. Furthermore, by connecting the sliding seat and the guide bracket through the locking components, the assembly of the two is more convenient, and the structural complexity of the sliding seat can be simplified, reducing the material requirements and production difficulty of the sliding seat, and enabling the sliding seat to bear the weight of the light unit.

[0009] A preferred embodiment is that, along the width of the through groove, both sides of the through groove are provided with wavy protrusions; the plate part is rectangular, and claw parts are provided at the four corners of the rectangle.

[0010] As can be seen from the above, this design allows the slide to slide more smoothly, optimizes the force distribution on the spring, and helps to improve the load-bearing capacity of the slide.

[0011] A further proposed solution is to use two guide rails and two sets of locking components, with each set of locking components corresponding to one of the two guide rails.

[0012] As can be seen from the above, this design ensures that the sliding seat has sufficient load-bearing capacity and can slide smoothly relative to the guide rail. On the other hand, it simplifies the structure of the telescopic adjustment unit, reduces the number of required parts, and lowers assembly complexity and production costs.

[0013] A further improvement is that the guide rail is also provided with a groove, which extends along the extension direction, with a through groove at the bottom of the groove and a wavy protrusion inside the groove.

[0014] As can be seen from the above, this design allows the wave-shaped protrusions, locking components, etc. to be housed in the groove, enabling the sliding seat to have a greater sliding stroke, thereby allowing the lamp unit to have a lower illumination height.

[0015] A further alternative is to use a compression spring or a tower spring as the elastic element.

[0016] As can be seen from the above, using compression springs or tower springs as elastic elements enables the elastic elements to apply stable pressure to the spring sheet, and makes the force required to control the sliding of the sliding seat more controllable.

[0017] A further improvement is that the telescopic adjustment unit also includes a face ring, which is fitted around the outer periphery of the connecting ring.

[0018] As can be seen from the above, the face ring is used to connect the external structure and the guide bracket, thereby optimizing the structure of the guide bracket and reducing the production difficulty of the guide bracket.

[0019] A further proposed solution is that the face ring includes a ring portion and an eave portion, with the eave portion located at the bottom of the ring portion and surrounding the outer periphery of the ring portion; the telescopic adjustment unit also includes two spring clips, which are installed on the ring portion and evenly distributed along the circumference of the ring portion.

[0020] As can be seen from the above, the spring clip is used to cooperate with the face ring to better and more reliably fix the telescopic adjustment unit to the external structure.

[0021] A further proposed solution is that the face ring and the connecting ring are rotatably connected, and the sliding seat has an integrally formed connecting column, or the sliding seat has a fixedly installed connecting column; or the face ring and the connecting ring are fixedly connected, and the sliding seat has a connecting rod, which is rotatably connected to the sliding seat.

[0022] As can be seen from the above, the design allows the lamp body unit to be adjusted in both circumferential and pitch lighting angles, thereby increasing the illumination range of the lamp body unit and enhancing the practicality of the ceiling light equipped with this telescopic adjustment unit.

[0023] A further proposed solution is to have a receiving compartment on the sliding seat, with a cable passage hole at the bottom of the receiving compartment; the telescopic adjustment unit also includes a cover, which is detachably connected to the sliding seat and closes over the opening of the receiving compartment.

[0024] As can be seen from the above, the sliding base is equipped with a housing compartment, which allows the sliding base to store functional modules such as power modules, thereby improving the integration of the ceiling light equipped with this telescopic adjustment unit. At the same time, it can also free up space inside the lamp body unit, allowing for the installation of more complex optical components, thereby improving the lighting effect of the ceiling light.

[0025] To achieve the second objective of this utility model, this utility model provides a ceiling light, including a lamp body unit, which further includes the aforementioned telescopic adjustment unit, and the lamp body unit is connected to a sliding seat.

[0026] As can be seen from the above, the ceiling light, by configuring the aforementioned telescopic adjustment unit, has different adjustment methods and adjustment feel, and the adjustment force can be adjusted when adjusting the illumination height of the light unit, thus improving the user experience; furthermore, it also facilitates production and assembly.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0036] Example of ceiling light Reference Figure 3 and Figure 4 The ceiling light 100 includes a telescopic adjustment unit 101 and a lamp body unit 102. The lamp body unit 102 is mounted on the telescopic adjustment unit 101, so that the lamp body unit 102 can adjust its own lighting height position through the telescopic adjustment unit 101, and can also adjust the circumferential lighting position and the pitch lighting position through the telescopic adjustment unit 101.

[0037] Combination Figure 5 The telescopic adjustment unit 101 includes a guide bracket 1, a sliding seat 2, a locking assembly 3, a face ring 4, and a spring clip 5. Combined with... Figure 6 The guide bracket 1 includes a connecting ring 11 and guide rails 12. There are two or more guide rails 12, and the two or more guide rails 12 are evenly distributed along the circumference of the connecting ring 11. Preferably, as in this embodiment, there are two guide rails 12. This design can ensure that it cooperates with the locking component 3 to provide sufficient support for the sliding seat 2, thereby enabling the sliding seat 2 to have sufficient load-bearing capacity. It can also enable the sliding seat 2 to slide smoothly relative to the guide rails 12. Furthermore, setting the number of guide rails 12 to two can also simplify the structure of the telescopic adjustment unit 101 to the greatest extent and reduce the number of required parts, thereby reducing assembly complexity and production costs.

[0038] The guide rail 12 is provided with a through groove 121, which penetrates the guide rail 12 in the thickness direction and extends along the extension direction of the guide rail 12. In addition, the guide rail 12 is provided with a wavy protrusion 122 on the adjacent side of the through groove 121. The wavy protrusion 122 includes multiple arc-shaped steps 1221, and the multiple arc-shaped steps 1221 are distributed along the extension direction of the guide rail 12; wherein, a locking position 1220 is formed between any two adjacent steps.

[0039] Preferably, each guide rail 12 has two wavy protrusions 122. A through groove 121 is located between the two wavy protrusions 122 along the width direction of the guide rail 12, and the two wavy protrusions 122 are arranged in a mirror-symmetrical manner. The thickness direction, width direction, and extension direction of the guide rail 12 are all perpendicular to each other. The design of the number of wavy protrusions 122 and their relative positions with the through groove 121 helps the sliding seat 2 slide more smoothly relative to the guide rail 12 via the locking assembly 3, optimizes the force distribution of the locking assembly 3, and also improves the load-bearing capacity of the sliding seat 2.

[0040] Furthermore, a groove 123 is formed on the guide rail 12. The groove 123 is recessed from the outer surface of the guide rail 12 to the inner surface (the side facing the sliding seat 2) of the guide rail 12 along the thickness direction of the guide rail 12, and the groove 123 extends along the extension direction of the guide rail 12. A through groove 121 is located at the bottom of the groove 123, while a wavy protrusion 122 is located within the groove 123. In the thickness direction of the guide rail 12, the depth of the groove 123 is greater than the height of the arc-shaped step 1221; that is, in the thickness direction of the guide rail 12, the distance between the top of the arc-shaped step 1221 and the outer surface of the guide rail 12 is greater than zero. This design allows the groove 123 to accommodate the wavy protrusion 122 and the locking component 3, preventing interference between the locking component 3 and the face ring 4, thereby increasing the sliding stroke of the sliding seat 2 and allowing the lamp unit 102 to have a lower illumination height.

[0041] The sliding seat 2 is movably disposed within the space enclosed by all the guide rails 12, and as described above, the sliding seat 2 is slidably connected to the guide rails 12 via the locking assembly 3. In this embodiment, the connection between the connecting ring 11 and the face ring 4 of the guide bracket 1 is preferably a rotatable connection, that is, the face ring 4 is rotatably fitted onto the connecting ring 11. Correspondingly, the sliding seat 2 is provided with a connecting post 21. The first end of the connecting post 21 is fixedly connected to the sliding seat 2 via a locking member, and the second end of the connecting post 21 is rotatably connected to the lamp body unit 102 via the locking member. This allows the lamp body unit 102 to adjust its circumferential lighting position (the adjustment of the circumferential lighting position requires the lamp body to be moved below the face ring 4) by the relative rotation of the sliding seat 2 and the face ring 4, or to adjust its pitch lighting position (the adjustment of the pitch lighting position requires the lamp body to be moved below the face ring 4) by the rotational connection between itself and the connecting post 21.

[0042] Based on the aforementioned rotatable connection between the connecting ring 11 and the face ring 4, as another optional solution, in some embodiments, the connecting post 21 can also be integrally formed on the sliding seat 2.

[0043] As another alternative, in some embodiments, the face ring 4 is fixedly connected to the connecting ring 11; based on this, a connecting rod is provided on the sliding seat 2, and the connecting rod is rotatably connected to the sliding seat 2. In addition, the lamp body unit 102 is also rotatably connected to the connecting rod, so that the lamp body unit 102 can adjust the circumferential lighting position by the relative rotation of the sliding seat 2 and the connecting rod (the adjustment of the circumferential lighting position can only be achieved by moving the lamp body below the face ring 4), or the lamp body unit 102 can adjust the pitch lighting position by its own rotational connection with the connecting rod (the adjustment of the pitch lighting position can only be achieved by moving the lamp body below the face ring 4).

[0044] The face ring 4 is designed to connect with the guide bracket 1, allowing the face ring 4 to be connected to an external structure (such as a ceiling) to fix the ceiling light 100 to the external structure. This also optimizes the structure of the guide bracket 1, reducing its manufacturing complexity. Furthermore, the connection design between the face ring 4 and the guide bracket 1, and the connection design between the sliding seat 2 and the connecting column 21 / link, allows the lamp body unit 102 to be adjusted for both circumferential and pitch lighting angles after extending below the face ring 4. This improves the illumination range of the lamp body unit 102, thereby enhancing the practicality of the ceiling light 100 equipped with this telescopic adjustment unit 101. It also allows for different manufacturing options for the telescopic adjustment unit 101, increasing its production flexibility.

[0045] Furthermore, the sliding base 2 is provided with a receiving compartment 22, and the bottom of the receiving compartment 22 is provided with a wire passage hole 221, which allows cables connected to the lamp body unit 102 to pass through the receiving compartment 22. By providing a receiving compartment 22 on the sliding base 2, the sliding base 2 can accommodate functional modules such as power modules, improving the integration of the ceiling light 100 equipped with this telescopic adjustment unit 101. At the same time, it can also free up space inside the lamp body unit 102, allowing for the installation of more complex optical components inside the lamp body unit 102, thereby improving the lighting effect of the ceiling light 100. In addition, the telescopic adjustment unit 101 also includes a cover, which is detachably connected to the sliding base 2. The cover closes on the opening of the receiving compartment 22, and the cover is used to prevent external dust from entering the receiving compartment 22, while also protecting the components inside the receiving compartment 22.

[0046] Combination Figure 7 The number of locking components 3 is two or more, and the number of locking components 3 is equal to the number of guide rails 12, so that one set of locking components 3 cooperates with one guide rail 12; that is, in this embodiment, the number of locking components 3 is two. The locking components 3 include spring pieces 31, bolts 32 and elastic elements 33.

[0047] Combination Figure 8 The spring clip 31 includes a plate portion 311 and a claw portion 312. The plate portion 311 has a through hole 3111 that penetrates through the plate portion 311. The claw portion 312 is bent to the plate portion 311, and the junction of the bend between the claw portion 312 and the plate portion 311 is preferably arc-shaped. The design of the claw portion 312 can enhance the structural strength of the plate portion 311 and also allow the claw portion 312 to engage with the locking position 1220 on the corrugated protrusion 122.

[0048] In this embodiment, since both sides of the through groove 121 are provided with wavy protrusions 122, the plate portion 311 is set into a rectangle in order to better cooperate with the guide rail 12. The number of claw portions 312 is four, and the four claw portions 312 are distributed at the four corners of the rectangle, that is, each corner of the rectangular plate portion 311 is provided with a claw portion 312. Of course, in some embodiments, it can also be designed as a circle, ellipse, etc., in which case the four claw portions 312 can be roughly distributed in a rectangular array. This design allows one wavy protrusion 122 to engage and connect with two claw portions 312 at the same time, thereby making the force on the spring piece 31 more balanced and helping to improve the load-bearing capacity of the sliding seat 2.

[0049] Bolt 32 is used to connect spring 31, guide bracket 1 and sliding seat 2. Specifically, during assembly, bolt 32 passes through elastic element 33, through hole 3111 on spring 31, and through groove 121 on corresponding guide rail 12 of guide bracket 1 in sequence, and is then threadedly connected to sliding seat 2. At this time, elastic element 33 abuts between spring 31 and bolt 32 to force spring 31 to move toward wavy protrusion 122, thereby making spring 31 cooperate with wavy protrusion 122 to fix sliding seat 2 in the desired position.

[0050] The elastic element 33 can be a compression spring or a tower spring, which allows the elastic element 33 to apply stable pressure to the spring piece 31 and makes the force required to control the sliding seat 2 more controllable. Preferably, as in this embodiment, the elastic element 33 is a tower spring, which makes the tower spring occupy less space (especially when compressed), thereby helping to reduce the thickness of the guide rail 12, reduce the depth of the groove 123, and help to miniaturize the telescopic adjustment unit 101 and the ceiling light 100.

[0051] It should be noted that, as an optional solution, such as Figure 7As shown, the spring piece 31 contacts the wavy protrusion 122 (i.e., the arc surface of the arc step 1221) of the plate portion 311 to achieve stepless adjustment of the sliding seat 2. As another optional solution, the spring piece 31 can also engage with any of the locking positions 1220 of the wavy protrusion 122 through the claw portion 312 to achieve stepped adjustment of the sliding seat 2, and can improve the load-bearing capacity and adjustment feel of the sliding seat 2; in this case, the plate portion 311 may or may not contact the arc step 1221. As can be seen, by designing the position of the wave-shaped protrusion 122 and configuring the locking component 3, the telescopic adjustment unit 101 can have different adjustment methods, such as stepless adjustment and stepped adjustment. In addition, based on the cooperation between the bolt 32 and the elastic element 33, the force of the adjustment slide seat 2 can be adjusted, and it can be ensured that the slide seat 2 is reliably selected at the desired adjustment position without being affected by the weight of the lamp body unit 102 of the ceiling lamp 100. Furthermore, by connecting the slide seat 2 and the guide bracket 1 through the locking component 3, the assembly of the two is more convenient, and the structural complexity of the slide seat 2 can be simplified, the material requirements and production difficulty of the slide seat 2 can be reduced, and the slide seat 2 can bear the weight of the lamp body unit 102.

[0052] The face ring 4 includes a ring portion 41 and an eave portion 42. When the face ring 4 is assembled with the guide bracket 1, the ring portion 41 is fitted over the connecting ring 11 of the guide bracket 1. The eave portion 42 is located at the bottom of the ring portion 41 and surrounds the outer periphery of the ring portion 41. There are two spring clips 5, which are installed on the ring portion 41 and are evenly distributed along the circumference of the ring portion 41. The spring clips 5 are used to cooperate with the eave portion 42 of the face ring 4 to reliably clamp and fix the ceiling light 100 to the external structure. Furthermore, the design of the spring clips 5 makes it easy to assemble and disassemble the ceiling light 100 from the external structure.

[0053] In summary, the design of the telescopic adjustment unit 101 of the ceiling light 100 enables the ceiling light 100 to have different adjustment methods and adjustment feel, and the adjustment force when adjusting the illumination height of the lamp body unit 102 is adjustable, which improves the user experience; in addition, it also makes the production and assembly of the ceiling light 100 more convenient.

[0054] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
