Description

Technical Field

[0001] This application relates to the field of lighting fixtures, and more particularly to a lighting device. Background Technology

[0002] In the field of lighting technology, lamps are indispensable equipment in daily life and industrial production. After a certain period of use, the lamp shade, light source and other components of the lamp will need to be cleaned, replaced or repaired due to dust accumulation, light decay or damage.

[0003] Currently, the detachable structures used in lighting fixtures on the market mainly exhibit the following typical forms and their inherent defects: The most traditional method is screw fixing, where multiple screws secure the lighting components to the base. While this method provides a secure connection, disassembly requires specialized tools such as screwdrivers, making the process cumbersome. This not only increases maintenance time and labor costs but also poses significant inconvenience and safety risks when working at heights. Furthermore, frequent tightening of screws can easily lead to stripping and damage to the connection structure.

[0004] Therefore, there is a need to provide a lighting device that can be quickly disassembled. Utility Model Content

[0005] In view of this, it is necessary to provide a quick-disassembly lighting device to solve the above problems.

[0006] This application provides a lighting device, including: Base; A lighting assembly is detachably connected to the base. The lighting assembly includes a base plate and a lampshade, wherein the lampshade is detachably connected to the base plate along the extending direction of the base plate. The lighting device further includes: A snap-fit ​​assembly is provided on the side of the substrate away from the lampshade. The snap-fit ​​assembly includes a support rod and a torsion spring wound around the support rod. The torsion spring has a first spring arm and a second spring arm arranged opposite to each other, and the distal ends of the first spring arm and the second spring arm each have a retaining section extending toward the substrate. A buckle plate is provided on the base. The buckle plate has a strip groove. The strip groove is directly opposite to the torsion spring. The first elastic arm extends into one end of the strip groove, and the second elastic arm extends into the other end of the strip groove. When the lighting assembly is disassembled in a vertical direction, the distal ends of the first spring arm and the second spring arm approach each other, so that the retaining segment moves along the groove and abuts against the edge of the buckle plate.

[0007] The aforementioned lighting device utilizes a torsion spring-type snap-fit ​​assembly on the back of the substrate to engage with a snap-fit ​​plate with a grooved strip on the base, replacing traditional screw fastening with an elastic snap-fit ​​connection. The torsion spring has first and second spring arms with retaining sections. During assembly, the retaining sections elastically open and engage with the edge of the snap-fit ​​plate for reliable fixation; during disassembly, simply pull the lighting assembly vertically to bring the distal ends of the two spring arms together to disengage the retaining sections.

[0010] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0011] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0012] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0013] according to Figures 1-9 This application provides a lighting device 100, including: a base 10, a lighting assembly 20, a buckle assembly 30 and a buckle plate 40.

[0014] The lamp assembly 20 is detachably connected to the base 10. The lamp assembly 20 includes a base plate 21 and a lampshade 22. The lampshade 22 is detachably connected to the base plate 21 along the extension direction of the base plate 21.

[0015] The latching assembly 30 is disposed on the side of the substrate 21 away from the lampshade 22. The latching assembly 30 includes a support rod 31 and a torsion spring 32 wound around the support rod 31. The torsion spring 32 has a first spring arm 321 and a second spring arm 322 arranged opposite to each other, and the distal ends of the first spring arm 321 and the second spring arm 322 each have a retaining section 3211 extending toward the substrate 21.

[0016] A buckle plate 40 is provided on the base 10. The buckle plate 40 has a strip groove 41. The strip groove 41 is positioned opposite to the torsion spring 32. The first spring arm 321 extends into one end of the strip groove 41, and the second spring arm 322 extends into the other end of the strip groove 41.

[0017] When the lighting assembly 20 is disassembled in the vertical direction F1, the distal ends of the first spring arm 321 and the second spring arm 322 approach each other, so that the retaining section 3211 moves along the strip groove 41 and abuts against the edge of the buckle plate 40. Specifically, the installation and disassembly process of the lamp assembly 20 relative to the base 10 can be understood as the process of the first spring arm 321 and the second spring arm 322 opening and closing under the drive of the torsion spring 32 to engage with the slot 41 of the buckle plate 40, so that the first spring arm 321 and the second spring arm 322 can suspend the lamp assembly 20 and the base 10 in the vertical direction F1 during disassembly.

[0018] Furthermore, the first spring arm 321, the second spring arm 322, and the torsion spring 32 are integrated into one unit. The retaining section 3211 is typically a bent or hook-shaped structure used to engage with the latching plate 40. The latching plate 40 is fixed to the base 10, and the size and position of the strip groove 41 are directly opposite to the torsion spring 32, allowing the first spring arm 321 and the second spring arm 322 to extend into both ends of the strip groove 41, respectively.

[0019] When installing the lighting assembly 20, push the lighting assembly 20 vertically towards the base 10 along the direction F1. Under the restoring force of the torsion spring 32, the first spring arm 321 and the second spring arm 322 tend to open again. The retaining segments 3211 at their far ends move away from the buckle plate 40, so that the retaining segments 3211 gradually cross the edge of the buckle plate 40 and disengage from the opening position of the strip groove 41. Thus, the first spring arm 321 and the second spring arm 322 rely on their own elasticity to press against the plate surfaces at both ends of the strip groove 41. By pressing against both ends of the strip groove 41, the buckle plate 40 and the buckle assembly 30 are fixed, thereby completing the assembly and positioning of the lighting assembly 20 and the base 10.

[0020] When it is necessary to disassemble the lamp assembly 20, pull the lamp assembly 20 vertically along F1. The edge of the strip groove 41 on the buckle plate 40 exerts a squeezing and guiding effect on the first spring arm 321 and the second spring arm 322, causing their distal ends to move closer to each other and driving the retaining section 3211 to move toward the buckle plate 40. This allows the retaining section 3211 to re-enter the opening area of ​​the strip groove 41 and form a fastening engagement with the edge of the buckle plate 40, thereby separating the base 10 from the lamp holder assembly.

[0021] Furthermore, by utilizing the continuous elastic clamping force provided by the torsion spring 32, the first spring arm 321 and the second spring arm 322 are reliably fastened to the buckle plate 40. On the other hand, during the disassembly process, the first spring arm 321 and the second spring arm 322 are guided and squeezed by the edge of the strip groove 41, causing the clamping section 3211 to move to the fastening position of the buckle plate 40, thereby pushing and pulling the lamp assembly 20 in the vertical direction F1, thus completing the quick assembly and disassembly of the lamp assembly 20 and the base 10.

[0022] In one specific embodiment, the snap-on plate 40 has an engaging portion 42. Specifically, the snap-on plate 40 is a plate-shaped structure. When viewed along the length of the strip groove 41, a plate-like structure is formed at one end of the strip groove 41 and near the free edge of the snap-on plate 40 as the engaging portion 42. The engaging portion 42 is continuously provided with the end of the strip groove 41 to provide a dedicated abutment and fastening area.

[0023] Furthermore, the distal ends of the first spring arm 321 and the second spring arm 322 of the torsion spring 32 are bent or made into hooks to form a retaining section 3211, so that the retaining section 3211 has a bent or hook-shaped end extending toward the latching plate 40. When the lamp assembly 20 is pulled vertically in the direction F1 from the installed state for disassembly, as the first spring arm 321 and the second spring arm 322 swing, the retaining section 3211 gradually approaches the latching plate 40, and during the disassembly stroke, it abuts and engages with the hook-shaped end of the plate surface of the engaging part 42 provided at one end of the strip groove 41, thereby forming a reliable engaging relationship between the plate surface structure of the latching plate 40 and the retaining section 3211.

[0024] In one specific embodiment, when viewed from above along the direction perpendicular to the surface of the substrate 21, the support rod 31 is located in the middle of the strip groove 41, while the first elastic arm 321 and the second elastic arm 322 extend from both sides of the support rod 31 relative to each other along the length direction of the strip groove 41.

[0025] Specifically, the support rod 31, serving as the rotation center of the torsion spring 32, is located in the middle of the strip groove 41, ensuring that the first spring arm 321 and the second spring arm 322 have equal lever arm lengths. In the assembled state, the two spring arms extend from the support rod 31 to both ends of the strip groove 41, with their extension paths consistent with the length direction of the strip groove 41. When the lamp assembly 20 is subjected to a vertical disassembly force F1, the two spring arms can produce elastic deformations of equal magnitude and opposite direction, ensuring that the movement trajectory of the retaining section 3211 within the strip groove 41 remains symmetrical.

[0026] Furthermore, when the lamp assembly 20 is pushed towards the base 10, the two spring arms of the torsion spring 32 simultaneously contact the two side edges of the strip groove 41 and undergo symmetrical elastic deformation due to compression. Since the support rod 31 is located in the middle of the strip groove 41, this symmetrical deformation allows the two retaining sections 3211 to simultaneously cross the edge of the snap-fit ​​plate 40, achieving smooth engagement. During disassembly, when a vertical pulling force is applied, the guiding force generated by the edge of the strip groove 41 on the two spring arms is equal in magnitude, ensuring that the distal ends of the two spring arms can approach each other evenly.

[0027] In one specific embodiment, the first spring arm 321 adopts a multi-segment bending structure, which includes, in sequence along its length: a first connecting arm 3212 connected to the body of the torsion spring 32, a second connecting arm 3213 connected to the first connecting arm 3212, and a retaining segment 3211 connected to the second connecting arm 3213.

[0028] There is an angle A between the first connecting arm 3212 and the second connecting arm 3213, and an angle B between the second connecting arm 3213 and the retaining section 3211. The opening of the angle A faces one side of the substrate 21, and the opening of the angle B faces the engaging part 42.

[0029] Specifically, through a two-stage bending design, the first connecting arm 3212 extends approximately along the length of the strip groove 41, the second connecting arm 3213 forms a transition near the substrate 21, and the retaining section 3211 is arranged near the engaging portion 42, thus giving the first spring arm 321 a zigzag spatial orientation. The double-angled structure with an opening direction ensures a smooth and stable force transmission path for the first spring arm 321 during disassembly, resulting in a smooth interaction between the retaining section 3211 and the engaging portion 42.

[0030] In one specific embodiment, the snap-fit ​​assembly 30 is further provided with a mounting plate 33 for supporting the torsion spring 32.

[0031] Mounting plate 33 is fixed to substrate 21 and can be a plate-like structure that fits against substrate 21. The surface of mounting plate 33 is parallel to substrate 21. On the side of mounting plate 33 away from substrate 21, it extends outward to form a first support plate 331 and a second support plate 332. The two support plates are erected vertically in a direction perpendicular to the surface of mounting plate 33 and are spaced apart from each other. Support rod 31 passes through the first support plate 331 and the second support plate 332 in sequence, with its two ends supported on the first support plate 331 and the second support plate 332 respectively. The spring coil of torsion spring 32 is sleeved in the middle of support rod 31 and is restricted between the first support plate 331 and the second support plate 332, so that torsion spring 32 always swings between the two support plates with support rod 31 as the axis of rotation during operation, avoiding axial movement or positional displacement.

[0032] In one specific embodiment, when the lamp assembly 20 is disassembled in the vertical direction F1, the strip groove 41 passes sequentially through the first connecting arm 3212, the included angle A between the first connecting arm 3212 and the second connecting arm 3213, and the second connecting arm 3213, until one end of the strip groove 41 abuts against the second connecting arm 3213, and the side of the engaging part 42 away from the strip groove 41 abuts against the holding section 3211.

[0033] Furthermore, when the lighting assembly 20 is pulled vertically along direction F1, causing it to gradually move away from the base 10 relative to the latching plate 40, it can be understood that one end of the strip groove 41 slides along the contour of the first elastic arm 321, sequentially sliding against the first connecting arm 3212, the included angle A, and the second connecting arm 3213, and finally abuts against the second connecting arm 3213. At the same time, the retaining section 3211 at the far end of the second connecting arm 3213 deflects towards the engaging part 42 under the elasticity of the torsion spring 32 and the geometric constraint of the fold line. When one end of the strip groove 41 abuts against the second connecting arm 3213, the side of the engaging part 42 on the outside of the strip groove 41 away from the strip groove 41 abuts against the bent or hook-shaped end of the retaining section 3211, forming a stable fit between the end of the strip groove 41 and the second connecting arm 3213, and between the engaging part 42 and the retaining section 3211.

[0034] It should be noted that, in this embodiment, each snap-fit ​​assembly 30 has two torsion springs 32, which are coaxially sleeved on the same support rod 31 and arranged on opposite sides along the length of the support rod 31. Corresponding snap-fit ​​plates 40 are also arranged opposite each other on the base 10.

[0035] In one specific embodiment, the mounting plate 33 has a fixing groove 333 extending along the length of the lamp, and the opening of the fixing groove 333 is open on one side facing the edge of the mounting plate 33.

[0036] The substrate 21 is provided with a protrusion 211 extending along the surface of the substrate 21 perpendicular to the substrate 21, and the protrusion 211 is inserted into the fixing groove 333.

[0037] Specifically, the fixing groove 333 is a U-shaped or recessed structure. The substrate 21 has a protrusion 211 on one side of the plate near the area where the snap-fit ​​assembly 30 is located. The protrusion 211 extends from the substrate 21 in a direction perpendicular to the plate surface of the substrate 21, and its cross-sectional size and shape are adapted to the inner cavity of the fixing groove 333.

[0038] In specific implementation, the groove wall of the fixing groove 333 can surround the protrusion 211 on three sides, and in conjunction with the contact between the substrate 21 and the mounting plate 33, the mounting plate 33 is effectively limited in the direction perpendicular to the substrate 21 and along the length of the lamp, preventing the mounting plate 33 from tilting or sliding relative to the substrate 21.

[0039] In one specific embodiment, the snap-fit ​​plate 40 adopts an L-shaped structure, consisting of a mutually perpendicular fitting part 43 and a sliding part 44. The fitting part 43 is fixed to the base 10 by means of screw connection or welding to ensure the stable positioning of the snap-fit ​​plate 40; the plate surface of the sliding part 44 is parallel to the plate surface of the base plate 21, and a strip groove 41 is formed on the sliding part 44.

[0040] Furthermore, once the fitting portion 43 is fixed, the sliding portion 44, by virtue of its parallel spatial position relative to the substrate 21, provides a guide plane for the snapping action of the torsion spring 32. A groove 41 is formed on the sliding portion 44 to ensure that the movement trajectories of the first spring arm 321 and the second spring arm 322 within the groove 41 remain parallel to the substrate 21, effectively preventing jamming caused by angular deviation.

[0041] In one specific embodiment, the lampshade 22 is composed of a light-transmitting portion 221 with an arc-shaped cross-section and an extension portion 222 provided at both ends of the light-transmitting portion 221.

[0042] Specifically, the light-transmitting part 221 serves as the main lighting area; while the extension part 222 extends horizontally from both ends of the light-transmitting part 221. When viewed in the vertical direction F1, the extension part 222 can be seen extending from both ends of the light-transmitting part 221 and extending into the receiving cavity 11 surrounded by the base 10 to form a plug-in fit, and is installed and fixed by the snap-fit ​​assembly 30.

[0043] In one specific embodiment, the extension portion 222 has a guide groove 2221, which is recessed along the extending direction of the lampshade 22.

[0044] The substrate 21 has guide portions 212 on both sides of its edge. The guide portions 212 are slidably limited within the guide grooves 2221 so that the lampshade 22 can slide relative to the substrate 21 along the extension direction of the substrate 21.

[0045] Specifically, the cross-sectional shape of the guide groove 2221 is preferably dovetail-shaped or T-shaped to ensure good guiding effect and anti-detachment performance.

[0046] Correspondingly, guide portions 212 that match guide grooves 2221 are provided on both sides of the substrate 21, and the shape and size of the guide portions 212 form a sliding fit with the guide grooves 2221.

[0047] During the assembly process, the guide portions 212 on both sides of the substrate 21 are aligned with the guide grooves 2221 of the lampshade 22 extension portion 222, and a pushing force is applied along the extension direction of the substrate 21 to achieve rapid assembly of the lampshade 22 and the substrate 21.

[0048] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
