Description

Technical Field

[0001] This utility model relates to the field of wall lamp technology, and in particular to a modular wall lamp and wall lamp combination. Background Technology

[0002] Traditional wall lamps are directly fixed to walls or other areas, mostly with a one-piece structure. Their lighting angle is fixed and their position and shape are monotonous, making it impossible to achieve new shapes and structures through modular assembly. As people's lighting needs increase, wall lamp structures with splicing functions have also been adopted. However, although the initial splicing wall lamps can achieve the splicing of multiple lighting fixtures, they require bolts and other connectors, making the connection between multiple lighting fixtures relatively cumbersome. Furthermore, bolts and other connectors are easily lost when carrying them, making them inconvenient to store, and thus greatly affecting the splicing efficiency of multiple lighting fixtures.

[0003] To address the aforementioned technical problems, Chinese utility model patent application CN201920833094.9 discloses "A Modular Wall Lamp with Interlocking Functions." This modular wall lamp includes a lamp body, a power port, and positive and negative contacts. The lamp body comprises a lamp cover, a base, a splicing buckle device, a fixing device, LED beads, and a switching circuit. The lamp body is a polygonal shape that can be interlocked. The lamp cover is mounted on the base. Positive and negative contacts and the splicing buckle device are installed on the side of the lamp body. The power port and the fixing device are installed on the base. LED beads and the switching circuit are installed inside the lamp body. One end of the power port output is connected to the input end of the switching circuit, and the other end is connected to the positive and negative contacts. The splicing buckle device has three pairs of slots, each pair separated by one side. The side without slots has corresponding buckles.

[0004] Although the modular wall lamp in the aforementioned patent application has a modular function, its modular buckle device has obvious defects: the buckle structure protrudes from the side of the lamp body and cannot be closed, which not only damages the overall appearance and aesthetics of the lamp body, but also makes it very easy to be damaged by bumps during storage or transportation, affecting its service life.

[0005] Therefore, existing modular wall lamps still need further improvement. Utility Model Content

[0006] The first technical problem this invention aims to solve is to provide a modular wall lamp with a snap-fit ​​mechanism that allows for concealment and storage when not in use, thus maintaining the overall aesthetic appeal, in light of the current state of the technology.

[0007] The second technical problem to be solved by this utility model is to provide a wall lamp combination that applies the above-mentioned modular wall lamp, in view of the current state of the prior art.

[0008] The technical solution adopted by this utility model to solve the first technical problem is: a modular wall lamp, comprising:

[0009] The main body of the wall lamp is a regular polygon, and the front of the main body of the wall lamp has a light-emitting part;

[0010] The back of the wall lamp body has a movable buckle at one side edge adjacent to the wall lamp body and a buckle engagement part at the other side edge adjacent to the wall lamp body. The movable buckle is rotatably connected to the back of the wall lamp body and has an unfolded state that flips outward and exposes the side edge of the wall lamp body as its rotation position changes, and a folded state that flips inward and is stored and hidden on the back of the wall lamp body.

[0011] When in the unfolded state, the movable buckle can form a limiting engagement with the buckle joint on the other wall lamp body, thereby connecting the two wall lamp bodies.

[0012] The positions of the movable buckles and buckle joints on the same wall lamp body can be two adjacent side edges or two non-adjacent side edges.

[0013] The aforementioned "regular polygon" refers to a plane figure with all sides of equal length and all interior angles equal, such as a regular hexagon and a square.

[0014] The aforementioned "limiting fit" refers to limiting the range of movement of components through physical structures (such as baffles or grooves) to prevent them from disengaging or loosening.

[0015] The aforementioned "rotatable connection" refers to a connection method in which components can rotate around an axis through mechanisms such as pins and hinges.

[0016] Considering that the movable buckle, when retracted to the back of the wall lamp body, still poses a risk of damage if exposed on the back wall, an improvement is made by providing a storage groove on the back of the wall lamp body near the corresponding side edge. The movable buckle is rotatably mounted on the inner wall of the storage groove via a pin. When the movable buckle is retracted, it is stored in the storage groove. This storage groove design allows the movable buckle to be hidden on the back of the wall lamp body, reducing the risk of bumps, maintaining a neat appearance, and improving safety and practicality.

[0017] Considering that the movable latch in its stored state is difficult to remove by hand and inconvenient to operate, as an improvement, the back of the wall lamp body is provided with a first pickup groove near the edge of the storage recess for picking up the movable latch. This first pickup groove provides a point of force application, making it easier for users to quickly pry out the movable latch, improving user experience and operational efficiency.

[0018] Considering that if the storage groove does not extend to the end wall, it may cause the buckle to flip improperly or cause structural interference, as an improvement, the outer periphery of the wall lamp body includes multiple sequentially connected end walls along the circumferential direction, and the storage groove extends and extends to the corresponding end wall on the wall lamp body. The through-type design ensures smooth rotation of the movable buckle, avoids mechanical interference, and simplifies the mold manufacturing process.

[0019] As an improvement, the wall lamp body also includes a power supply, which is a lithium battery or a removable dry cell battery. The wall lamp body also has a charging port for charging the lithium battery. Powered by a built-in lithium battery or dry cell battery, it supports wireless use, and the charging port design facilitates repeated charging, achieving truly flexible installation and portable lighting.

[0020] To simplify the limiting and engaging structure between the movable latch and the latch engagement part, the latch engagement part includes a latch engagement groove on the back of the wall lamp body and a latch limiting plate in the latch engagement groove. The movable latch includes a latch body and a limiting baffle at the free end of the latch body. When the movable latch is in the unfolded state, it is retracted into the latch engagement groove, and the limiting baffle of the movable latch abuts against the inner side of the latch limiting plate. The cooperation between the latch limiting plate and the limiting baffle achieves mechanical interlocking, ensuring a firm connection and preventing the lamp from shifting.

[0021] To facilitate the retrieval of the movable latch in the locked state, a second retrieval groove is provided on the back of the wall lamp body near the edge of the latch engagement slot for retrieval of the movable latch in the folded state. The second retrieval groove provides operating space, making it easier for the user to pry out the latch, enhancing the reversibility and ease of use of the function.

[0022] To ensure the stability of the movable buckle during rotation, the end face of the buckle body away from the limiting baffle is constructed as an arc-shaped surface structure.

[0023] The main body of the wall lamp can be an equilateral triangle, a regular triangle, or a regular hexagon. However, considering that too many or too few sides of the polygon can restrict the splicing direction or cause the combined shape to be uncoordinated, the main body of the wall lamp is preferably a regular hexagon. One of the two adjacent side edges of the wall lamp body is provided with the aforementioned movable buckle, and the other is provided with the aforementioned buckle joint. The regular hexagonal design balances structural stability and splicing freedom, supports multi-angle combinations (such as honeycomb, linear, etc.), and adapts to various scene requirements.

[0024] The technical solution adopted by this utility model to solve the second technical problem is as follows: a wall lamp assembly, comprising at least two wall lamps joined together, each of which is a splicable wall lamp as described above. By arbitrarily splicing multiple wall lamps, a coherent lighting system is formed, meeting the needs of large-area or decorative lighting and enhancing visual appeal.

[0025] Compared with existing technologies, the advantages of this utility model are as follows: The movable buckle of this utility model is rotatably set on the back of the wall lamp body, allowing it to be flipped outwards to complete the splicing when in use, and flipped inwards to be perfectly hidden behind the lamp body when not in use. This design not only maintains the integrity and simple beauty of the wall lamp's appearance when not spliced, avoiding the visual damage caused by protruding buckles, but also greatly reduces the risk of buckle damage due to bumps during storage, transportation, and daily use, significantly improving the product's durability and lifespan. At the same time, this retractable buckle structure requires no disassembly of additional parts, making operation simple and quick, further optimizing the splicing experience and storage portability, and balancing aesthetics, practicality, and reliability.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0036] Example 1

[0037] Figures 1-7 This illustration shows a preferred embodiment of the modular wall lamp and wall lamp assembly of the present invention. The modular wall lamp has a main body 1 that is generally hexagonal. The outer shell of the main body 1 can be injection molded from engineering plastic, making it lightweight and durable. The front of the main body 1 has a light-emitting section 10, which is covered by a translucent acrylic panel and contains LED beads and a light guide plate to achieve uniform illumination. The back of the main body 1 is a mounting surface for contact with a wall or other surface and also features a modular splicing structure.

[0038] See Figure 2 On the back of the wall lamp body 1, a movable latch 12 is provided near one of the side edges (i.e., one side of a regular hexagon), and a latch engagement part is provided near the other adjacent side edge. The movable latch 12 is rotatably connected to the back of the wall lamp body 1 via a pin 1211. Specifically, the back of the wall lamp body 1 has a receiving groove 11 near the corresponding side edge, which extends and penetrates to the corresponding end wall 103 (i.e., the side of the side edge) on the wall lamp body 1. The movable latch 12 is mounted on the inner side wall of the receiving groove 11 via the pin 1211, so that the movable latch 12 can rotate around the pin 1211. Specifically, the left and right sides of the end of the latch body 121 of the movable latch 12 have outwardly protruding pins 1211 that extend in the same straight line, and a pair of shaft holes 111 are provided on the two opposite side walls of the receiving groove 11, in which the two pins 1211 of the movable latch 12 can be rotatably limited.

[0039] See also Figure 2The movable buckle 12 has two states: an unfolded state and a retracted state. In the unfolded state, the movable buckle 12 flips outward and is exposed relative to the side edge (i.e., end wall) of the wall lamp body 1. At this time, the buckle body 121 of the movable buckle 12 protrudes from the end wall 103. In the retracted state, the movable buckle 12 flips inward and is completely stored in the storage groove 11, thus hiding behind the back of the wall lamp body 1. The movable buckle 12 is neither exposed on the end wall 103 of the wall lamp body 1 nor exposed relative to the back of the wall lamp body 1, thus not affecting the overall appearance.

[0040] For ease of operation, the back of the wall lamp body 1 is provided with a first pickup groove 110 near the edge of the storage groove 11. The first pickup groove 110 is an arc-shaped shallow groove structure that gradually slides into the storage groove 11 from a distance. Users can insert their fingers or tools into the first pickup groove 110 to easily pry open the movable buckle 12, so that it changes from the closed state to the open state.

[0041] The snap-fit ​​engagement portion includes a snap-fit ​​groove 13 located on the back of the wall lamp body 1 and a snap-fit ​​limiting plate 131 located within the groove. The snap-fit ​​groove 13 is a recessed area whose size matches the movable snap-fit ​​12. The snap-fit ​​limiting plate 131 extends from the bottom wall of the snap-fit ​​groove 13 towards the open side of the snap-fit ​​groove 13. The movable snap-fit ​​12 includes a snap-fit ​​body 121 and a limiting baffle 122 located at the free end of the snap-fit ​​body 121. When the movable snap-fit ​​12 is in the unfolded state, a movable snap-fit ​​12 from another wall lamp can be inserted into the snap-fit ​​groove 13 of this wall lamp. At this time, the limiting baffle 122 of the movable snap-fit ​​12 will press against the inner side of the snap-fit ​​limiting plate 131 (i.e., the side closer to the center of the wall lamp body 1), forming a limiting fit and preventing the two wall lamp bodies 1 from separating.

[0042] See Figure 6 To facilitate the removal of the movable buckle 12 from the snap-fit ​​groove 13, a second pickup groove 132 is provided on the back of the wall lamp body 1 near the edge of the snap-fit ​​groove 13. Similar to the structure of the first pickup groove 110, the second pickup groove 132 is also an arc-shaped shallow groove structure that gradually slides into the snap-fit ​​groove 13 from a distance. The second pickup groove 132 provides operating space for flipping the movable buckle 12, making it convenient for the user to pick up or separate the assembled wall lamp.

[0043] See Figure 3 and Figure 4 The end face of the buckle body 121 of the movable buckle 12 away from the limiting baffle 122 (i.e. the end of the connecting pin 1211) is constructed as an arc-shaped surface structure 120 to ensure that the movable buckle 12 rotates smoothly without interference.

[0044] See Figure 4Regarding power supply, the wall lamp body 1 is equipped with a power supply 2. In this embodiment, the power supply 2 is a removable dry cell battery. A battery compartment 101 is provided in the middle of the back of the wall lamp body 1. The battery compartment 101 can hold three dry cell batteries. The opening of the battery compartment 101 is covered with a cover 102 by a snap-fit ​​connection or a threaded connection. The wall lamp body 1 also has a control circuit inside, including a switch and an LED driver circuit, for controlling the lighting.

[0045] During assembly, the user can change the movable latch 12 of one of the wall lamps from the folded state to the unfolded state, and insert the movable latch 12 into the latch engagement groove 13 of another wall lamp. The locking is achieved through the cooperation of the limiting baffle 122 and the latch limiting plate 131. Multiple wall lamps can be assembled in a similar manner to form wall lamp combinations of various shapes, such as linear arrangement, honeycomb arrangement, etc.

[0046] This embodiment also discloses a wall lamp assembly, comprising at least two wall lamps joined together, each wall lamp being a regular hexagonal wall lamp as described above. Through arbitrary splicing, the wall lamp assembly can form a coherent lighting system; for example, three wall lamps can be spliced ​​into a 120-degree angle pattern, or six wall lamps can be spliced ​​into a honeycomb cluster, meeting the needs of large-area or decorative lighting. The movable latches 12 and latch engagement parts on each wall lamp are alternately arranged, ensuring that any side can be assembled, providing high flexibility.

[0047] Example 2

[0048] Figure 8 This illustration shows a preferred embodiment of the modular wall lamp and wall lamp assembly of the present invention. This embodiment is essentially the same as Embodiment 1, with the main difference being the design of the power supply 2. In this embodiment, the power supply 2 is a lithium battery, which is non-removably built into the wall lamp body 1. A charging port 21 is provided on one end wall 103 (side edge) of the wall lamp body 1. The charging port 21 is a USB Type-C interface, which can be used to charge the lithium battery. The wall lamp body 1 has an internal charging management circuit for charging and discharging control. This design eliminates the need for external power cords, achieving truly wireless lighting, suitable for situations without power outlets or requiring portable lighting. When assembled, multiple wall lamps can be independently powered without the need for connecting wires, simplifying installation.

[0049] Based on the above embodiments, other embodiments can be obtained by replacing and improving the relevant technical features. For example, the shape of the wall lamp body 1 can also be a regular quadrilateral (i.e., a square). The movable buckle 12 and the buckle engagement part are respectively located on two adjacent side edges. The structure of the storage groove 11 and the buckle engagement groove 13 is the same as in Embodiment 1, but the size is adjusted to accommodate the square shape. The regular quadrilateral wall lamp can be used to splice into a grid-like or stepped combination, which is suitable for modern minimalist style decoration. Other features such as the rotation mechanism of the movable buckle 12 and the pickup groove are consistent with Embodiment 1. Of course, the shape of the wall lamp body 1 can also be an equilateral triangle. The movable buckle 12 and the buckle engagement part are respectively located on two adjacent side edges. Since the equilateral triangle has fewer sides, the splicing direction is limited, but unique geometric patterns can be formed, such as serrated or radial combinations. The storage and unfolding mechanism of the movable buckle 12 is the same as in Embodiment 1, ensuring aesthetics and practicality.
