Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lighting functional module installation structure and a lighting fixture. Background Technology

[0002] In lighting fixtures, such as traditional tri-proof lamps, the light source carrier plate is usually mounted on the lamp holder, while electrical components such as the driver power supply and sensors are mounted on the light source carrier plate and placed inside the lamp holder.

[0003] To facilitate the installation and disassembly of functional modules such as power supplies and sensors, the applicant's prior application, CN221801709U "Functional Module Installation Structure and Application of Lighting Fixtures with Such Installation Structure", discloses a functional module installation structure that is easy to disassemble. The structure includes: a mounting base and a functional module. The functional module includes a mounting plate, and the mounting plate is provided with a locking knob. The locking knob includes a knob body that is rotatably mounted on the mounting plate and a limiting rib provided on the knob body. The mounting base is provided with a limiting hole that runs vertically through the mounting plate so that the limiting rib can pass through. Taking the sensor module as an example, when installing the sensor module, first insert the sensor module's plug into the socket of the mounting substrate to pre-position the sensor module at one end. Then, insert the positioning post of the mounting plate at the other end of the sensor module into the positioning hole on the mounting substrate. The limiting rib of the locking knob also aligns with the limiting hole on the mounting substrate. After the limiting rib of the locking knob passes through the limiting hole of the mounting substrate, rotate it at a certain angle. The two ends of the limiting rib can be limited to the lower side of the outer periphery of the limiting hole, thereby preventing the limiting rib from coming out of the limiting hole. At this time, the locking knob is in the locked state. When unlocking is required, rotate the knob body in the opposite direction until the limiting rib and the limiting hole of the mounting substrate are aligned vertically. At this time, the locking knob is in the unlocked state. Move the sensor module upward, and the limiting rib can come out of the limiting hole. Then, lift it up, and the plug at the first end of the sensor module can come out of the socket of the mounting substrate. This completes the disassembly of the sensor module.

[0004] However, the aforementioned knob-type functional module mounting structure has certain shortcomings: First, the functional module has an operable rotating locking knob, and there are relatively many components involved. Furthermore, the locking knob needs to be manufactured separately and assembled onto the functional module's mounting plate, involving additional assembly processes and increasing the production cost of the lamp. Second, when the functional module needs to be unlocked, clear indications of the reverse rotation direction of the locking knob and the unlocking position are required, or limit-stop mechanisms are needed, increasing the user's operational difficulty and reducing the user experience. Utility Model Content

[0005] The first technical problem to be solved by this utility model is to provide a lamp functional module installation structure that addresses the current state of the technology, involves fewer parts, has lower production costs, and makes it easier for users to assemble and disassemble the functional modules.

[0006] The second technical problem to be solved by this utility model is to provide a lamp that applies the above-mentioned functional module installation structure, in view of the current state of the prior art.

[0007] The technical solution adopted by this utility model to solve the first technical problem is as follows: a lamp functional module mounting structure, including a mounting base plate and a functional module detachably mounted on the mounting base plate. The functional module has downwardly extending elastic buckles on two opposite side walls of its main body. There is an active gap between each elastic buckle and the side wall of the main body of the functional module, allowing the corresponding elastic buckle to elastically swing in the lateral direction. The bottom of each elastic buckle also has a buckle portion protruding in the lateral direction. The mounting base plate has a vertically penetrating limiting hole for each elastic buckle to pass through. After each elastic buckle is pressed by an external force and swings laterally a set distance relative to the main body of the functional module, it can pass downward through the corresponding limiting hole. After the external force is released from the pressure on each elastic buckle, each elastic buckle returns to its initial position, limiting its buckle portion below the peripheral edge of the corresponding limiting hole on the mounting base plate.

[0008] The aforementioned "functional module" refers to a module unit installed on the mounting base plate (usually the light source carrier plate) of the lamp and performing a specific function, such as the lamp's sensor module, power drive module, or emergency kit module.

[0009] The “main body of the functional module” mentioned above can be understood as the entire frame or shell of the functional module, which can serve as the basis for other auxiliary components. Specifically, the main body of the functional module is the entire frame except for the elastic buckle.

[0010] The term "horizontal" as used above can be understood as a horizontal direction, and is limited to the length or width of the main body of the functional module. In a further interpretation, "horizontal" can be understood as a direction substantially perpendicular to the sidewalls of the main body of the functional module.

[0011] The “side wall” of the main body of the aforementioned functional module can generally be understood as the other side walls of the main body of the functional module besides the bottom wall, including the top side wall or other side wall portions that extend upward from the bottom side wall or downward from the top side wall. That is, the elastic buckle in this application can also be connected to the top side wall of the functional module and then extend downward.

[0012] Considering that asymmetrical snap-fit ​​fasteners can easily lead to uneven force during installation, affecting the alignment accuracy of the functional module during installation, the elastic snap-fit ​​fasteners on the two opposite side walls of the main body of the functional module are arranged symmetrically. The symmetrical arrangement of the elastic snap-fit ​​fasteners improves installation balance, facilitates one-handed pressing of the two opposite elastic snap-fit ​​fasteners, reduces the risk of alignment deviation, and enhances structural reliability.

[0013] Generally speaking, the latching part of the spring buckle can protrude towards the side away from the main body of the functional module, or it can protrude towards the side where the main body of the functional module is located. However, in order to better meet the user's operating habits and facilitate the user to apply force with one hand (such as applying force to two opposite elastic buckles by using the thumb and forefinger to move them closer to each other), the latching part of each elastic buckle protrudes towards the side away from the main body of the functional module.

[0014] To facilitate smoother installation of the elastic clip through the limiting hole, the elastic clip includes a vertically extending spring arm. A clip portion is connected to the bottom of the spring arm, and each clip portion has a root connected to the spring arm and an end portion away from the spring arm. The bottom wall of the clip portion is constructed with an arc-shaped guide surface that gradually slopes upward from the root to the end. The arc-shaped guide surface provides progressive guidance, reduces frictional resistance, and makes it easier for the elastic clip to slide into the limiting hole, improving installation efficiency.

[0015] The aforementioned "vertically extending spring arm" is limited by the spring arm extending in a vertical direction. That is, the extension direction of the spring arm can be at a certain angle relative to the vertical direction (such as less than 30°). Specifically, it can be set according to the extension angle of the side wall of the main body of the functional module. Generally, the side wall of the main body of the functional module extends vertically, while the spring arm is tilted from top to bottom outward (that is, the side away from the main body of the functional module).

[0016] To facilitate connection with the side wall of the main body of the functional module and form a corresponding movable gap, the elastic buckle includes a vertically extending spring arm. The buckle part is connected to the bottom of the spring arm, and the top of the spring arm has a bent part that bends and extends toward the main body of the functional module. The bent part connects with the side wall of the main body of the functional module, and the movable gap is formed between the main body of the spring arm and the side wall of the main body of the functional module.

[0017] To prevent excessive deformation during the swing of the spring arm, which could affect its service life or cause breakage, a support rib is provided between the top of the spring arm and the side wall of the main body of the functional module to support both. The support rib extends downward from the bent part of the spring arm. The support rib provides additional support, limits the swing amplitude of the spring arm, prevents plastic deformation, and extends its service life.

[0018] As an improvement, the main body of the functional module includes a housing, and each of the elastic buckles is integrally formed with the housing. The buckles and housing are integrally molded, reducing the number of parts, improving overall structural integrity, and lowering production and maintenance costs.

[0019] To further ensure the stability of the functional module installation, the main body of the functional module is elongated, and the elastic buckles are located on two opposite side walls along the width direction of the functional module. The elastic buckles on both sides along the width direction ensure multi-point fixation of the elongated functional module, avoiding localized stress concentration and improving overall stability. After the elastic buckles on the two sides along the width direction are engaged in the limiting holes, they are both constrained by the limiting holes and simultaneously limited in the longitudinal direction (perpendicular to the transverse direction), ensuring the stability of the functional module installation.

[0020] Considering the lack of fixing points at the ends of the functional modules, which makes them prone to displacement along their length after installation, the functional modules have a first end and a second end opposite each other along their length. The elastic buckle on the functional module is located adjacent to the second end. The bottom of the first end of the functional module also has a plug extending away from the second end. The top of the mounting base has a side opening for the plug to be inserted from the side. The plug at the end of the functional module, engaging with the plug, forms an end fixation, preventing longitudinal sliding of the module. Combined with the aforementioned elastic buckle (limiting hole), this further enhances the anti-displacement capability of the mounting structure.

[0021] The technical solution adopted by this utility model to solve the second technical problem is as follows: a lamp, including a lamp housing, a mounting base plate disposed inside the lamp housing, and a functional module disposed on the mounting base plate, wherein the mounting base plate is a lamp board, and the functional module is mounted on the lamp board using the above-mentioned lamp functional module mounting structure.

[0022] Compared with existing technologies, the advantages of this utility model are as follows: The installation structure of the lamp functional module of this utility model adopts an elastic buckle design set on the side wall of the functional module, eliminating the knob assembly step in the locking knob scheme of the prior art, simplifying the production process, and reducing material and labor costs. During installation, only pressing the elastic buckle and swinging it horizontally is required to insert it into the limiting hole. After releasing the pressure, it automatically resets and locks itself. During disassembly, pressing one side is enough to unlock it. No rotation operation is required throughout the process, avoiding the confusion of knob direction identification, effectively improving disassembly and assembly efficiency, and significantly reducing the risk of misoperation. The limiting method of the elastic buckle after horizontal pressing and reset relies on the elastic deformation of the material to achieve self-locking. There is no wear problem of mechanical rotating parts. The rigid contact between the buckle and the periphery of the limiting hole limits the vertical direction, ensuring the fixation is stable and avoiding the risk of loosening and falling off, thus enhancing the reliability of the functional module installation.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] 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.

[0032] Figures 1-7This illustration shows a preferred embodiment of the lamp's functional module mounting structure and the lamp itself. The lamp in this embodiment is illustrated using a long, rectangular tri-proof lamp as an example. The lamp body includes a lamp housing (not shown) and a mounting base 1 disposed within the lamp housing. Both the lamp housing and the mounting base 1 are long and rectangular, extending in the same direction. The lamp housing generally includes an upper shell that snaps shut with the upper shell and a light-transmitting lampshade, both of which are long and rectangular. A light source is located at the bottom of the mounting base 1, and a functional module 2 is located at the top. The light source at the bottom of the mounting base 1 faces the light-transmitting lampshade. In this embodiment, the "functional module 2" refers to a module unit mounted on the mounting base 1 (generally a light source carrier plate) of the lamp, performing a specific function, such as a sensor module, a power drive module, or an emergency kit module.

[0033] See Figures 4-7 The installation structure of functional module 2 will be described using the power drive module as an example. The main body of functional module 2 includes a long, narrow housing 22, which can be integrally injection molded from high-strength engineering plastic. The width direction of housing 22 (i.e., the horizontal direction, such as...) Figure 3 Each of the two opposite sidewalls 221 in the W direction is provided with a downwardly extending elastic buckle 21. The two elastic buckles 21 are arranged symmetrically to ensure balance during installation.

[0034] Each elastic latch 21 includes a vertically extending elastic arm 211, the main body of which is a flat plate. The top of the elastic arm 211 is connected to the side wall of the housing 22 via a bend 212, and a lateral movable gap 3 is formed between the main body of the elastic arm and the side wall 221, allowing the elastic arm 211 to swing laterally elastically under external pressure. The bottom of the elastic arm 211 is connected to a latch 210, which protrudes laterally toward the side away from the housing 22. Its bottom wall is designed as an arc-shaped guide surface 214 that gradually slopes upward from the root to the end to reduce frictional resistance when inserted into the limiting hole 11.

[0035] The snap-fit ​​part of the elastic snap 21 is located below the bottom wall of the functional module, and the distance between the two in the vertical direction can be adapted to the thickness of the mounting base plate 1.

[0036] The mounting base 1 is typically a metal lamp plate with two vertically penetrating limiting holes 11 on its surface. These holes 11 are rectangular and slightly larger than the locking portion 210 of the elastic latch 21, allowing the spring arm 211 and the bottom locking portion 210 to pass through smoothly. During installation, the user presses the elastic latches 21 on both sides of the functional module 2 simultaneously with their thumb and forefinger, causing the spring arm 211 to swing inward. The retraction of the locking portion 210 aligns vertically with the corresponding limiting hole 11 on the mounting base 1. At this point, the functional module 2 is moved vertically downward, allowing the locking portion 210 to pass through the limiting hole 11. Simultaneously, the bottom wall of the functional module 2's main body abuts against the top of the mounting base 1. After releasing the pressure, the spring arm 211 returns to its original position due to material elasticity, and the locking portion 210 locks onto the lower surface around the limiting hole 11, completing the locking process. The functional module 2 cannot detach from the mounting base 1.

[0037] In some embodiments, a support rib 213 is added between the top of the spring arm 211 and the side wall of the housing 22. The support rib 213 extends downward from the bent portion 212 to a certain distance, generally not exceeding the middle of the spring arm 211. The support rib 213 provides additional support to limit the swing amplitude of the spring arm 211 (avoiding excessive deformation) without affecting the elastic function of the spring arm 211. This design can extend the service life of the elastic buckle 21 and prevent plastic fracture caused by repeated pressing.

[0038] See Figure 7 Functional module 2 in its length direction (e.g. Figure 7 The functional module 2 has a first end 201 and a second end 202 located in the L direction. The elastic buckle 21 on the functional module 2 is located adjacent to the second end 202. The bottom of the first end 201 of the functional module 2 also has a plug 23 extending away from the second end 202. A corresponding opening, a side-opening socket 12, is provided on the mounting base 1. In some embodiments, there are two plugs 23 on the first end 201 of the functional module 2, arranged sequentially along the width direction of the functional module 2. Two sockets 12 are also correspondingly provided on the mounting base 1. During installation, the plug 23 is first inserted laterally into the socket 12, and then the elastic buckle 21 is pressed to fix the second end 202. The socket 12 cooperates with the plug 23 to prevent the functional module 2 from sliding along its length, enhancing overall stability. The plug 23 at the end of the functional module 2, cooperating with the socket 12 to form an end fixation, prevents the module from sliding longitudinally. This, combined with the aforementioned elastic buckle 21 (limiting hole 11), further strengthens the anti-displacement capability of the mounting structure.

[0039] Both the housing 22 and the elastic buckle 21 of functional module 2 are made of plastic and are integrally molded. During production, they are directly injection molded using a mold. The elastic arm 211 is naturally connected to the bent part 212 of the side wall of the housing 22, and the movement gap 3 is formed by the cavity reserved in the mold. The one-piece design reduces assembly steps, lowers production costs, and ensures the connection strength and consistency between the elastic buckle 21 and the housing 22.

[0040] The installation and disassembly process of the lamp functional module mounting structure in this embodiment is as follows: When installing the functional module 2, the plug 23 of the functional module 2 can be inserted into the socket 12 of the mounting base plate 1 to achieve a pre-position of the functional module 2 at one end. The user presses the elastic buckles 21 on both sides of the other end of the functional module 2 in the width direction with his thumb and forefinger, causing the spring arm 211 to swing inward. The retraction of the buckle part 210 aligns with the corresponding limiting hole 11 on the mounting base plate 1. Then, the functional module 2 is moved down or swings downward with the first end 201 as the swing center. The buckle part 210 can pass through the limiting hole 11, and at the same time, the bottom wall of the main body of the functional module 2 also abuts against the top of the mounting base plate 1. After releasing the pressure, the spring arm 211 returns to its original position due to the elasticity of the material, and the buckle part 210 is locked on the lower surface of the periphery of the limiting hole 11, thus completing the locking. The functional module 2 cannot fall upward off the mounting base plate 1. When unlocking is required, both elastic buckles 21 can be pressed with one hand to make the buckling part 210 of the elastic buckle 21 align with the corresponding limiting hole 11 on the mounting base plate 1. Move the functional module 2 upward, and the elastic buckle 21 can be disengaged from the limiting hole 11. Then, lift it up, and the insertion block 23 of the first end 201 of the functional module 2 can be disengaged from the insertion port 12 of the mounting base plate 1, thus completing the disassembly of the functional module 2.

[0041] Based on the above embodiments, other embodiments can be obtained by replacing and improving the relevant technical features. For example, the shape of the functional module 2 is not limited to a long strip. For example, the main body of the functional module 2 is rectangular or cuboid, and symmetrical elastic buckles 21 are provided on two opposite sets of the four side walls. The mounting base 1 has four sets of limiting holes 11. During installation, pressing the four side buckles simultaneously can achieve multi-point fixation. For another example, the arc-shaped guide surface 214 of the buckle part 210 in the above embodiments can be replaced with a combination structure of inclined surface and arc transition. Specifically, the bottom wall of the buckle part 210 is an arc surface that transitions from an inclined surface to an arc surface from the root to the end. For yet another example, the main body of the functional module 2 is still long strip, but the first end 201 insert 23 in the length direction can be omitted, and multiple sets of two opposite elastic buckles 21 in the width direction can be provided and arranged sequentially along the length direction.
