Description

Technical Field

[0001] This utility model relates to the field of home furnishing and decoration equipment technology, and in particular to a reflective component and a simulated flame device. Background Technology

[0002] A simulated flame device is a device that uses technology to simulate the effect of flames. It utilizes the principle of reflective elements in a reflective component to reflect light, and by continuously changing the position, angle, and direction of the reflective elements, it simulates the flickering and changing effect of flame light. Simulated flame devices are commonly used in interior decoration, such as in hotels, restaurants, and bars, to create a warm, romantic, or mysterious atmosphere. They are widely used in various occasions that require creating a flame atmosphere or conducting related demonstrations.

[0003] Currently, most simulated flame devices on the market use a motor to drive a rotating shaft (a plastic rod of a certain length), with a high-brightness reflector inserted through the shaft. The shaft drives the reflector to rotate, and in conjunction with lighting and an imaging screen, the reflected light from the reflector is projected onto the screen, creating a dynamic simulated flame effect. The most common shape for the rotating shaft is linear, with one motor driving one shaft. For a square simulated flame device, four motors and four shafts are needed to form a square. For more complex shapes such as circular, polygonal, or multi-zigzag simulated flame devices, multiple motors driving multiple shafts must be used, with the shafts pieced together to form the complex shape.

[0004] In particular, for circular simulated flame devices, the only way to approximate the simulation is to increase the number of motors and rotating shafts as much as possible and increase the number of polygon variables.

[0005] This will cause the following problems:

[0006] 1. The overall structure of the product is relatively large, with a diameter of over 500mm.

[0007] 2. Since the shaft can only use a straight line shape, when the shape is complex, one motor is needed to drive each straight line edge. Multiple motors need to be set up in the whole. The mechanical friction and vibration of multiple motors are superimposed, resulting in loud noise. Utility Model Content

[0008] In view of this, the purpose of this utility model is to provide a reflective component and a simulated flame device. The reflective component can be formed into various complex shapes by using a bent corrugated tube and a round bar. A single motor can drive the corrugated tube to rotate the round bar on a limiting component, thereby causing the reflective component to rotate and reflect light, achieving the effect of simulated flame light flashing and changing. It features less mechanical friction and vibration, lower noise, and a compact structure.

[0009] This utility model provides a reflective component, including a corrugated tube, a round bar, a reflective element, a limiting element, and a motor;

[0010] One end of the bellows is fixedly connected to the output shaft of the motor, and the other end is fixedly connected to the round bar. The bellows is bent so that there is an angle between the bar and the output shaft of the motor.

[0011] The limiting member is sleeved on the round bar to limit the position of the round bar;

[0012] The reflector is fixedly mounted on the corrugated pipe and / or the round bar;

[0013] The motor is used to drive the corrugated pipe and the round bar to rotate. The round bar rotates on the limiting member. The reflector rotates synchronously with the corrugated pipe and / or the round bar to reflect light. There is one motor and multiple corrugated pipes and round bars. After multiple bends, the ends of the multiple round bars and multiple corrugated pipes face the motor and together form a preset shape.

[0014] Specifically, the corrugated pipe is a hollow flexible tube, and the corrugated pipe remains bent when it rotates.

[0015] Specifically, the corrugated pipe includes a pipe body and an elastic element. One end of the pipe body is fixedly connected to the motor, and the other end of the pipe body is sleeved on the round bar. The elastic element is installed on the outside, inside or inside the pipe body to provide a restoring force when the pipe body rotates.

[0016] Specifically, the bellows is an elastic element. When the motor drives the bellows to rotate, the bellows undergoes elastic deformation, and the shape of the bellows remains bent.

[0017] Specifically, the corrugated pipe is provided with connectors at both ends. The connectors are used to connect the motor or the round bar. The connector is a sleeve. The output shaft of the motor or the round bar passes through the opening of the connector and extends into the corrugated pipe. The side of the connector is provided with an opening groove along its circumference for fixing the reflector.

[0018] Specifically, the corrugated pipes and the round bars are connected in series, each of the corrugated pipes is bent at a preset angle, and an included angle is formed between any adjacent round bars. The preset shape formed by the multiple corrugated pipes and the multiple round bars is an arc shape, a wave shape, a spiral shape, or a multi-fold line shape.

[0019] Specifically, there are multiple limiting members, each with a through hole. The round bar passes through the through hole and is mounted on the limiting member, rotating within the through hole of the limiting member.

[0020] This utility model also provides a simulated flame device, including a housing and a reflective component as described in any of the above claims, wherein the motor and the limiting component are fixedly mounted on the housing.

[0021] Specifically, the simulated flame device also includes an imaging plate, which is fixedly connected to the housing. The imaging plate is disposed on one side of the corrugated pipe and the round bar. When the corrugated pipe and the round bar rotate, the reflector rotates accordingly and reflects light onto the imaging plate.

[0022] Specifically, the corrugated tube is bent and forms a polygonal shape with the round bar, and the imaging plate is arranged in a circular ring around the outside of the reflective component.

[0023] In summary, the reflective component of this utility model embodiment can be formed into various complex shapes by using a bent corrugated tube in conjunction with a round bar. A single motor can drive the corrugated tube to rotate the round bar on the limiting member, thereby causing the reflective component to rotate and reflect light, achieving the effect of simulating the constantly changing flickering of flame light. Mechanical friction and vibration are reduced, noise is lower, and the structure is compact.

[0024] Furthermore, the reflective components can be arc-shaped, wavy, spiral-shaped, or multi-zigzag-shaped, making them suitable for designing simulated flame devices of different shapes.

[0025] Furthermore, the corrugated pipe includes a pipe body and an elastic element, which is used to assist the pipe body in undergoing elastic deformation when it rotates. Attached Figure Description

[0040] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0041] The following detailed explanation uses specific examples:

[0042] like Figures 1 to 2As shown, the first embodiment of this utility model provides a reflective component, including a corrugated tube 10, a round bar 30, a reflective element (not shown in the figure), a limiting element 40, and a motor 50;

[0043] One end of the bellows 10 is fixedly connected to the output shaft of the motor 50, and the other end is fixedly connected to the round bar 30. The bellows 10 is bent so that there is an angle between the bar body of the round bar 30 and the output shaft of the motor 50.

[0044] The limiting component 40 is sleeved on the round bar 30 to limit the position of the round bar 30;

[0045] The reflector is fixedly mounted on the corrugated pipe 10 and / or the round bar 30;

[0046] The motor 50 is used to drive the bellows 10 and the round bar 30 to rotate. The round bar 30 rotates on the limiting member 40. The reflector rotates synchronously with the bellows 10 and / or the round bar 30 to reflect light. There is one motor 50 and multiple bellows 10 and round bars 30. After multiple bends, the ends of the multiple round bars 30 and multiple bellows 10 face the motor 50 and together form a preset shape.

[0047] In this embodiment, the bellows 10 is a hollow flexible tube, which remains bent during rotation. Specifically, the bellows 10 is a hollow sleeve, with its two ends respectively fitted onto the output shaft of the motor 50 and the round rod 30. Specifically, the bellows 10 is a circular hollow flexible tube with a circular cross-section, allowing it to rotate in any direction and bend into any shape without affecting its rotation.

[0048] In this embodiment, the corrugated pipe 10 includes a pipe body 11 and an elastic element 12. One end of the pipe body 11 is fixedly connected to the motor 50, and the other end of the pipe body 11 is sleeved on the round bar 30. The elastic element 12 is installed on the outer side, inner side, or inside the pipe wall of the pipe body 11 to provide a restoring force for shape recovery when the pipe body 11 rotates. The material of the pipe body 11 can be a soft and elastically deformable material, such as rubber.

[0049] Specifically, the elastic element 12 can be a spring. Utilizing the flexibility of the elastic element 12, the tube body 11 is wound around the outer or inner wall surface of the tube body 11. Optionally, the elastic element 12 can also be embedded inside the wall of the tube body 11. The elastic element 12 gives the tube body 11 high axial elasticity. When the bellows 10 is not installed, under the reset action of the elastic element 12, the bellows 10 is in a state of... Figure 2 (a) shows the straightened state. When the bellows 10 is installed, the bellows 10 is in the extended state. Figure 2(b) In the bent state shown, the motor 50 drives the bellows 10 to rotate axially. When the entire bellows 10 undergoes arc-shaped bending under the constraint and pressure of the motor 50 and / or the round bar 30, the elastic element 12 can self-adaptively deform, reducing the inner ring diameter and increasing the outer ring diameter, while the bellows 10 can still rotate normally. The basic principle utilizes the variability of the elastic element 12. When in a bent state, the pitch on the inner side of the arc of the elastic element 12 is further compressed, and the pitch on the outer side of the arc of the elastic element 12 is further increased. During rotation, the elastic element 12 changes from the inner ring diameter to the outer ring diameter, and the pitch of the elastic element 12 increases from small to large. When the outer diameter changes to the inner diameter, the elastic element 12 changes from the outer ring diameter to the inner ring diameter, and the pitch of the elastic element 12 decreases from large to small. In other words, regardless of how the shape of the bellows 10 changes, the elastic element 12 can automatically adjust its pitch as the bellows 10 rotates. This allows the bellows 10 to solve the rotation problem under different shapes, not only for curved shapes, but also for complex shapes such as circles, polygons, and multi-zigzag shapes.

[0050] In this embodiment, the reflective component includes multiple corrugated tubes 10 and multiple round rods 30, which are connected in series. Each corrugated tube 10 is bent at a preset angle, and an included angle is formed between any adjacent round rods 30. The preset shape formed by the multiple corrugated tubes 10 and the multiple round rods 30 is an arc, a wave, a spiral, or a multi-fold line.

[0051] In this embodiment, there are multiple limiting members 40. The limiting members 40 have through holes. The round rod 30 is disposed on the limiting member 40 through the through holes and rotates within the through holes of the limiting member 40.

[0052] Specifically, in this embodiment, multiple corrugated pipes 10 and multiple round bars 30 are located in the same plane, and there is an included angle between any adjacent round bars 30. The limiting member 40 is used to support and fix the round bars 30. The last round bar 30 at the tail end faces the motor, and the closed loop forms a polygon. The polygon formed by the multiple corrugated pipes 10 and the multiple round bars 30 is approximately circular.

[0053] The second embodiment of this utility model provides a reflective component, the general structure of which is the same as that of the first embodiment. For example... Figure 3 As shown, the difference is that the bellows 10 in this embodiment is an elastic element 12. When the motor 50 drives the bellows 10 to rotate, the bellows 10 undergoes elastic deformation, and the shape of the bellows 10 remains bent.

[0054] In this embodiment, the two ends of the corrugated pipe 10 are provided with connectors 20. The connectors 20 are used to connect the motor 50 or the round bar 30. The connectors 20 are sleeves. The output shaft of the motor 50 or the round bar 30 passes through the opening of the connectors 20 and extends into the corrugated pipe 10. The side of the connectors 20 is provided with an opening groove along the perimeter for fixing the reflector.

[0055] The third embodiment of this utility model provides a reflective component, whose general structure is the same as that of the first embodiment. The difference is that the corrugated tube 10 in this embodiment is a stainless steel flexible conduit, which is integrally formed, and the corrugated tube 10 includes the stainless steel flexible conduit. The stainless steel flexible conduit is made of 304 stainless steel or 301 stainless steel and is used as a protective conduit for wires, cables, and signal wires and cables of automated instruments, with specifications ranging from 3mm to 150mm. Ultra-small diameter stainless steel flexible conduits (inner diameter 3mm-25mm) are mainly used for the protection of sensing circuits of precision optical scales and industrial sensor circuits, and have good flexibility, corrosion resistance, high temperature resistance, wear resistance, and tensile strength.

[0056] The fourth embodiment of this utility model also provides a simulated flame device, such as... Figure 4 As shown, the device includes a housing 60 and a reflective component as described in any of the above embodiments, with a motor 50 and a limiting member 40 fixedly mounted on the housing 60.

[0057] In this embodiment, the simulated flame device also includes an imaging plate 61, which is fixedly connected to the housing 60. The imaging plate 61 is disposed on one side of the corrugated pipe 10 and the round bar 30. When the corrugated pipe 10 and the round bar 30 rotate, the reflector rotates accordingly and reflects the light onto the imaging plate 61.

[0058] In this embodiment, the corrugated tube 10 is bent and forms a polygonal shape with the round rod 30, and the imaging plate 61 is arranged in a circular ring around the outside of the reflective component. The distance between each round rod 30 and the imaging plate 61 (imaging screen) is the same, and the distance between each corrugated tube 10 and the imaging plate 61 (imaging screen) is also the same, to ensure that the imaging distance is equal, the flame effect is realistic and there are no shadows.

[0059] Specifically, the housing 60 is a disc-shaped base plate, the motor 50 is a stepper motor, and the bottoms of the limiting member 40 and the motor 50 are fixedly connected to the housing 60. The bellows 10 round bars 30 form a suspended shape, with the last round bar 30 facing the motor, forming a polygon that is approximately circular. One end of the bellows 10 is fixedly connected to the output shaft of the motor 50, and the other end is fitted onto the round bars 30. When the motor 50 drives the bellows 10 to rotate, the round bars 30 rotate synchronously on the limiting member 40, thereby driving the reflector to rotate. The shape of the bellows 10 is restricted to bend to maintain the position and orientation of the round bars 30. The reflector is a reflector sheet, and the angle, direction, and size of each reflector are randomized to produce a simulated flame beam effect.

[0060] like Figure 4 As shown, in this embodiment, multiple corrugated pipes 10 and multiple round bars 30 are connected in series, wherein the corrugated pipes 10 and the round bars 30 are sequentially and fixedly connected to each other. The round bars 30 are straight pipes, responsible for forming the straight part of the multi-fold line, while the corrugated pipes 10 are bent pipes, responsible for bending and twisting when the corrugated pipes 10 rotate as a whole, so that the corrugated pipes 10 as a whole maintain the shape of the multi-fold line.

[0061] The output shaft of the motor 50 is straight. The first section of the bellows 10 is fitted onto the output shaft of the motor 50. After the first section of the bellows 10 is bent, it is connected to the second section of the round bar 30. The other end of the round bar 30 is then connected to the third section of the bellows 10. After the third section of the bellows 10 is bent, it is connected to the next section of the round bar 30. Each bellows 10 is bent at the same angle in one direction. Multiple bellows 10 and multiple round bars 30 form a multi-fold bellows 10.

[0062] The bottom of the limiting member 40 is fixedly mounted on the housing 60. The round bar 30 is mounted on the limiting member 40 and can rotate on the limiting member 40. The limiting member 40 is used to restrict the position of the round bar 30 when the bellows 10 rotates, so that the overall shape of the bellows 10 remains unchanged. The round bar 30 can be mounted on the limiting member 40 in two ways: either by opening a through hole in the limiting member 40 through which the round bar 30 passes, with the diameter of the through hole being slightly larger than the diameter of the round bar 30; or by having the limiting member 40 hold the round bar 30 in place, with the diameter of the holding opening being slightly larger than the diameter of the round bar 30.

[0063] The reflector (not shown in the figure) can be set on the round bar 30 or on the bellows 10. When the bellows 10 and the round bar 30 rotate, the reflector rotates accordingly.

[0064] In this embodiment, a near-circular simulated flame effect is simulated by a polygonal bellows 10, which rotates on the limiting member 40 under the drive of the motor 50.

[0065] Multiple corrugated pipes 10 and multiple round bars 30 are connected in series, and then the above components are driven to rotate by a single motor 50. The purpose of this is to use corrugated pipes 10 as corner connections while reducing product size. In this embodiment, the power is output by the motor 50, and the corrugated pipes 10 serve as transmission nodes, with the fundamental purpose of solving the transmission problem. By using the bending of the corrugated pipes 10 as intermediate connections, the size of the product can be significantly reduced, replacing the existing connection structure where multiple motors 50 drive multiple sides separately with smaller corrugated pipes 10.

[0066] Existing technologies typically use multiple plastic or stainless steel rods to form a polygon. The more sides a polygon has, the closer its overall shape is to a circular structure. However, since each side corresponds to one plastic or stainless steel rod and one side corresponds to one motor, the more sides there are, the more motors there are, resulting in a larger overall size and greater noise, making it difficult to achieve a perfect circular flame display effect.

[0067] This invention uses a single motor 50 to directly drive multiple corrugated pipes 10 and multiple round bars 30. One end of each corrugated pipe 10 is fixedly connected to the output shaft of the motor 50 and rotates with the output shaft. Compared to a polygonal structure where multiple motors 50 drive multiple plastic or stainless steel bars, this invention solves the noise problem caused by multiple motors 50. The mechanical friction noise of this invention is significantly lower than the friction noise generated by multiple transmission mechanisms on the market. Furthermore, due to the use of fewer parts, the product size can be made very small. While products on the market have a diameter of over 500mm, this invention, by using a single motor 50, can achieve a diameter of 160mm or less.

[0068] In this embodiment, the shape formed by multiple round rods 30 and multiple corrugated pipes 10 is a polygonal approximation of a circle. The motor 50, round rods 30 and corrugated pipes 10 form a ring, and the imaging plate 61 is arranged around the outer ring of the ring.

[0069] In this embodiment, the simulated flame device also includes a limiting member 40. The bottom of the limiting member 40 is fixedly disposed on the housing 60. The limiting member 40 is used to support the bellows 10, help limit the shape of the bellows 10, and prevent the bellows 10 from deforming during rotation.

[0070] Specifically, the simulated flame device has a compact structure. The motor 50, bracket 30, wear-resistant parts 50, and corrugated pipe 10 form a circle. A light-blocking plate 62 is installed inside the circle, and an imaging plate 61 surrounds the circle. The overall size of the product is reduced to a diameter of 160mm or less, which greatly reduces the space occupied by the product compared to existing technologies.

[0071] In this embodiment, optionally, the simulated flame device also includes a light-blocking plate, which is fixedly connected to the housing 60. The light-blocking plate and the imaging plate 61 are respectively disposed on both sides of the corrugated pipe 10 and the round bar 30. The light-blocking plate is used to block light from interfering with the imaging plate 61.

[0072] In this embodiment, optionally, the simulated flame device also includes a light source, which is fixedly connected to the housing 60. The light emitted by the light source illuminates the reflector, and the imaging plate 61 is disposed in the path of the light reflected from the reflector.

[0073] Specifically, the reflector creates a rotating ring effect. A ring of light sources, consisting of multiple sets of gold LED beads, surrounds the reflector, emitting light similar in color to flames. The LED beads are 3030 type, with a power of 0.5W, and are fixedly mounted on the housing 60. An imaging plate 61 is fixedly mounted on the outermost ring of the housing 60. The imaging plate 61 can be a semi-transparent brown color. In this embodiment, the LED beads are preferably 3030 type, but not limited to this model; 5050 type, 0.5W power, or other combinations of types and powers can also be used. Different types or powers of LED beads produce different light effects; the color, power, and brightness of the light significantly affect the flame effect.

[0074] When using the simulated flame device, light emitted from the light source shines onto the reflector. The reflector reflects the light through its mirror surface, projecting the light onto the imaging plate 61 to form an image. The imaging plate 61 displays the shape of the reflector, which is flame-shaped. The reflector can be made of PET hot-dip galvanized aluminum film with a thickness within 0.1mm, which can reflect the light from the LED beads. After light reflection, the image projected onto the imaging plate 61 creates a flame effect. The motor 50 drives the corrugated tube 10 and the round bar 30 to rotate, continuously rotating the reflector and creating a dynamic flame simulation effect.

[0075] Large-sized products on the market typically use a polygonal structure with multiple motors and over 50 straight rods. However, because each side requires a separate motor, the product size cannot be reduced. This embodiment, however, uses a corrugated pipe 10 for transmission in the bending section, allowing a single motor 50 to drive the corrugated pipe 10, thus solving the problems of the existing technology. The corrugated pipe 10 of this invention can be bent, deformed, and rotate at any angle.

[0076] In summary, the reflective component of this utility model embodiment can be formed into various complex shapes by using a bent corrugated tube 10 in conjunction with a round rod 30. A single motor 50 can drive the corrugated tube 10 to rotate the round rod 30 on the limiting member 40, thereby causing the reflective component to rotate and reflect light, achieving the effect of simulating the constantly changing flickering of flame light. Mechanical friction and vibration are reduced, noise is lower, and the structure is compact.

[0077] Furthermore, the reflective components can be arc-shaped, wavy, spiral-shaped, or multi-zigzag-shaped, making them suitable for designing simulated flame devices of different shapes.

[0078] Furthermore, the corrugated pipe 10 includes a pipe body 11 and an elastic element 12, which is used to assist the pipe body 11 in undergoing elastic deformation when it rotates.

[0079] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
