Description

Technical Field

[0001] This utility model relates to the field of drive device technology, and specifically to a random drive device. Background Technology

[0002] To meet people's pursuit of a better quality of life, many decorative items are designed with dynamic structures. Driven by a mechanism, parts of the item move to create a realistic effect, enhancing its aesthetic appeal and practicality. For example, in electronic candles, the flame is a dynamic structure. When activated, the flame simulates the flame of a traditional candle, appearing more lifelike and natural, thus increasing its visual appeal.

[0003] However, the current driving mechanism for decorative items is conventional mechanical, such as using cam structures or other transmission components to drive the moving parts. This driving method is relatively mechanical and rigid, lacking randomness and flexibility, resulting in poor observability. Utility Model Content

[0004] This invention provides a random drive device to solve the problem of existing drives being rigid and inflexible.

[0005] In one embodiment, a random drive device is provided, comprising:

[0006] The housing has a mounting cavity and a rolling cavity;

[0007] A random drive assembly includes an electromagnetic drive, a magnetic rolling element, and a magnetic follower. The electromagnetic drive is installed in the mounting cavity, the magnetic rolling element is installed in the rolling cavity, and the magnetic follower is used to connect to the object to be driven. The electromagnetic drive is used to electromagnetically drive the magnetic rolling element to roll in the rolling cavity. The rolling of the magnetic rolling element can drive the magnetic follower to swing through magnetic force, thereby causing the object to be driven to swing.

[0008] In one embodiment, a mounting seat is provided inside the mounting cavity for mounting the object to be driven, and the magnetic follower is used to connect with the object to be driven located inside the housing; or, a mounting seat is provided on the outside of the housing for mounting the object to be driven, and the magnetic follower is used to connect with the object to be driven located outside the housing.

[0009] In one embodiment, the bottom surface of the rolling cavity is concave, and the magnetic follower rolls within the concave surface.

[0010] In one embodiment, the lower end of the rolling cavity is a base with the concave surface, the base being a flexible structure, or the base having a flexible layer that forms the concave surface.

[0011] In one embodiment, the magnetic rolling element is a ball bearing structure.

[0012] In one embodiment, the electromagnetic drive includes a circuit board and an electromagnetic coil, the circuit board being electrically connected to the electromagnetic coil, and the circuit board being used to control the electromagnetic coil to electromagnetically drive the magnetic rolling element to roll.

[0013] In one embodiment, the mounting cavity includes a first mounting cavity and a second mounting cavity, the magnetic follower is mounted in the first mounting cavity, the electromagnetic drive is mounted in the second mounting cavity, and the first mounting cavity and the second mounting cavity are independent of each other.

[0014] In one embodiment, the first mounting cavity is filled with a liquid medium, and the random drive component is used to drive the object to be driven to swing within the liquid medium cavity.

[0015] In one embodiment, the sidewall of the first mounting cavity is a light-transmitting wall, or the housing is provided with a light-transmitting window located on the sidewall of the first mounting cavity.

[0016] In one embodiment, a light source is further included, and the mounting cavity further includes a third mounting cavity. The light source is mounted in the third mounting cavity, and a light-transmitting wall or light-transmitting hole is provided between the third mounting cavity and the first mounting cavity. The light source is used to illuminate the object to be driven in the first mounting cavity.

[0017] According to the random drive device of the above embodiment, the random drive device is provided with a random drive assembly, which includes an electromagnetic drive component, a magnetic rolling component, and a magnetic follower component. The electromagnetic drive component can generate a magnetic field to drive the magnetic rolling component to roll. There is a magnetic attraction or repulsion between the magnetic rolling component and the magnetic follower component. When the magnetic rolling component rolls, it will drive the magnetic follower component to move together through magnetic force. The magnetic follower component is installed together with the flame simulation component, thereby driving the object to be driven to swing. Because the magnetic rolling component rolls in the rolling cavity, its motion freedom is high and its randomness is high, which enables the object to be driven to swing more randomly, improving the flexibility and randomness of the swing of the object to be driven, thereby improving the visual appeal of the object to be driven.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0034] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0035] The component serial numbers used in this document, such as "first" and "second," are merely for distinguishing the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages). In this document, the axial direction refers to the length direction of the random drive device, which is also the vertical direction in the installed state; the radial direction refers to the left-right or front-back direction of the random drive device, which is also the horizontal direction in the installed state.

[0036] In one embodiment, a random driving device is provided. This random driving device is used to drive movable parts on a decorative item. The movable parts are objects to be driven. The random driving device is connected to the objects to be driven to drive the objects to perform random movements, thereby enhancing the aesthetic appeal of the objects to be driven.

[0037] Decorative installations may include, but are not limited to, electronic candles, movable toys, and aquariums. The following description will use electronic candles as an example.

[0038] The object to be driven is a flame simulator. A light source is also installed within the random drive device. The flame simulator has a reflective surface, and the light source emits light onto this reflective surface to simulate a candle flame. The flame simulator can be oscillating; when the random drive device is activated, the flame simulator emits light in an oscillating manner, simulating the flickering motion of a traditional candle flame. Compared to ordinary lamps, this random drive device not only provides illumination but also simulates the dynamic flame of a traditional candle, offering higher realism and creating a more atmospheric lighting experience.

[0039] Please refer to Figures 1 to 2 The random drive device of this embodiment mainly includes a housing 1, a driveable object 2, and a random drive component 3. The driveable object 2 is a flame simulation component, also referred to simply as a flame sheet. The housing 1 includes a first housing 1a and a second housing 1b, which are arranged side-by-side along the length (axial direction) of the electronic candle. The driveable object 2 is installed inside the first housing 1a, and the random drive component 3 is installed inside the second housing 1b.

[0040] The first housing 1a and the second housing 1b can be detachably connected, allowing the assembly consisting of the object to be driven 2 and the first housing 1a to be replaced and disassembled for maintenance. Alternatively, the first housing 1a and the second housing 1b can be an integral structure to improve the stability of the connection between them, thus meeting the needs of certain application scenarios.

[0041] The first housing 1a and the second housing 1b can each be composed of multiple parts, allowing different parts of the first housing 1a and the second housing 1b to be made of different materials, creating a wider variety of color-blocked appearances. Alternatively, different parts of the first housing 1a and the second housing 1b can use the same color, resulting in a simpler overall design. The composition of the first housing 1a and the second housing 1b into multiple parts facilitates the installation of internal components.

[0042] The shape of the housing 1 can vary to meet the preferences of different consumers. This embodiment uses a long cylindrical shape as an example. The random drive device can also have various installation configurations, such as suspended inverted installation or vertical installation facing upwards. This embodiment uses suspended inverted installation as an example.

[0043] The housing 1 has a mounting cavity 11 and a rolling cavity 12. The second housing 1b includes an outer shell 14 and an inner shell 15. The inner shell 15 can be fixed to the outer shell 14 by means of snap-fit, screw connection, interference fit, etc. The inner shell 15 is used to form multiple cavities and to install components. For example, the inner shell 15 separates a relatively independent rolling cavity 12 in the mounting cavity 11.

[0044] In this embodiment, the mounting cavity 11 includes a first mounting cavity 111 and a second mounting cavity 112. The first mounting cavity 111 is located within the first housing 1a, and the rolling cavity 12 and the second mounting cavity 112 are located within the second housing 1b, with the rolling cavity 12 positioned between the first mounting cavity 111 and the second mounting cavity 112. Specifically, the first mounting cavity 111 is located at the bottom of the housing 1, the second mounting cavity 112 is located at the top of the housing 1, and the rolling cavity 12 is located in the middle, slightly above the middle, or slightly below the middle of the housing 1. The first mounting cavity 111, the rolling cavity 12, and the second mounting cavity 112 are arranged sequentially from bottom to top.

[0045] In other embodiments, the first mounting cavity 111, the rolling cavity 12, and the second mounting cavity 112 can also be arranged in other ways. For example, the rolling cavity 12 and the second mounting cavity 112 can be arranged side by side, with the first mounting cavity 111 located below the rolling cavity 12. This can form an inverted L-shaped lamp, which can meet the usage needs of some consumers.

[0046] In this embodiment, the object to be driven 2 can be a flame-shaped structure, and the object to be driven 2 is installed in the mounting cavity 11. Specifically, the object to be driven 2 is installed in the first mounting cavity 111.

[0047] In this embodiment, all or part of the outer wall of the first mounting cavity 111 is a transparent structure, such as transparent glass or transparent plastic, so that the outer wall of the first mounting cavity 111 forms a light-transmitting structure, and the light reflected or reflected by the flame part 21 can illuminate the outside of the random drive device, and the user can observe the light emitted by the flame part 21 through the transparent shell.

[0048] In other embodiments, a portion of the outer wall of the first mounting cavity 111 is transparent or semi-transparent. For example, the outer wall of the first mounting cavity 111 may have a transparent window, while other portions of the outer wall of the first mounting cavity 111 may be non-transparent. The transparent window may be annular and its height may be greater than the height of the flame portion 21. This portion of the transparent or transparent outer wall may also display the luminous flame portion 21.

[0049] In other embodiments, the object to be driven 2 may also be partially or entirely mounted on the outside of the housing 1, with the object to be driven 2 directly exposed to the outside of the housing 1 to emit light, such as simulating the flame of a traditional candle located at the top of the candle.

[0050] Please refer to Figure 2 and Figure 4 In this embodiment, the object to be driven 2 includes a flame part 21 and a connecting part 22. The flame part 21 is a flame sheet structure, and one or both sides of the flame part 21 are reflective surfaces. The reflective surfaces are smooth planes with good reflective properties. When a light source illuminates the flame part 21, the flame part 21 reflects light to form a flame similar to self-luminous flame, thus simulating the flame of a candle. The connecting part 22 can be a rod-shaped or rope-shaped structure. A mounting seat 4 is provided in the first mounting cavity 111. The mounting seat 4 is suspended in the first mounting cavity 111. For example, the mounting seat 4 is a mounting plate. The mounting seat 4 divides the first mounting cavity 111 into an upper part and a lower part. The middle part of the mounting seat 4 can be provided with a mounting hole 41. The connecting part 22 of the object to be driven 2 passes through and is installed in the mounting hole 41 of the mounting seat 4. The upper end of the connecting part 22 is located in the upper part of the first mounting cavity 111, and the lower end of the connecting part 22 is located in the lower part of the first mounting cavity 111. The flame part 21 is mounted on the upper end of the connecting part 22, and the flame part 21 is located in the upper part of the first mounting cavity 111. The connecting part 22 can be limited and swing-connected with the mounting base 4 by a limiting member, so that the flame part 21 can swing relative to the mounting base 4 through the connecting part 22.

[0051] Please refer to Figure 2 and Figure 3The random drive assembly 3 includes an electromagnetic drive 31, a magnetic rolling element 32, and a magnetic follower 33. The electromagnetic drive 31 is installed in the mounting cavity 11, and the magnetic rolling element 32 is installed in the rolling cavity 12. The magnetic rolling element 32 can roll within the rolling cavity 12. The magnetic follower 33 is connected to the end of the connection portion 22 of the object to be driven away from the flame portion 21, and the magnetic follower 33 and the object to be driven are installed as an integral structure. The magnetic follower 33 is located in the lower part of the first mounting cavity 111. The electromagnetic drive 31 is used to generate a magnetic field by electromagnetic means to drive the magnetic rolling element 32 to roll randomly within the rolling cavity 12. The magnetic rolling element 32 and the magnetic follower 33 are magnetic structures with the same or different magnetic properties. There is a magnetic attraction or magnetic repulsion between the magnetic rolling element 32 and the magnetic follower 33. When the magnetic rolling element 32 is driven to roll, the rolling of the magnetic rolling element 32 can drive the magnetic follower 33 to move together through magnetic force, thereby causing the object to be driven 2 to swing randomly.

[0052] The electromagnetic drive component 31 is installed in the second mounting cavity 112. The electromagnetic drive component 31 and the object to be driven 2 are installed in different cavities. The two are independent of each other, which can avoid the influence of the heat generated by the object to be driven 2 on the electromagnetic drive component 31 and improve the service life of the random drive device.

[0053] The electromagnetic drive unit 31 includes a circuit board 311 and an electromagnetic coil 312. The circuit board 311 is electrically connected to the electromagnetic coil 312. The circuit board 311 is used to control the electromagnetic coil 312 to generate a magnetic field. One or more driving methods can be preset in the circuit board 311, including an irregular random driving method to control the electromagnetic coil 312 to drive the magnetic rolling element 32 to move irregularly and randomly in the rolling cavity 12. Of course, the circuit board 311 can also be equipped with a regular driving method to control the electromagnetic coil 312 to drive the magnetic rolling element 32 to move regularly in the rolling cavity 12.

[0054] The circuit board 311 is also electrically connected to the light-emitting body of the object to be driven 2. The circuit board 311 is used to control the light emission of the object to be driven 2. The circuit board 311 and the object to be driven 2 are located in different cavities, and they can be electrically connected by a cable. The housing 1 is provided with corresponding wire holes so that the cable can run from the first mounting cavity 111 to the second mounting cavity 112. Preferably, the cable does not enter the rolling cavity 12.

[0055] Please refer to Figure 4 The second mounting cavity 112 is provided with an electromagnetic coil support 5, and the electromagnetic coil support 5 has a receiving cavity 51. The electromagnetic coil 312 is installed in the receiving cavity 51. The size of the receiving cavity 51 is adapted to the electromagnetic coil 312, and the electromagnetic coil 312 is snapped into the receiving cavity 51.

[0056] The electromagnetic coil bracket 5 can be fitted with a screw 52. The upper end of the screw 52 protrudes and abuts against the circuit board 311, and the lower end of the screw 52 extends to the vicinity of the receiving cavity 51. The electromagnetic coil 312 is electrically connected to the circuit board 311 through the screw 52 and the cable.

[0057] In other embodiments, the electromagnetic coil 312 may also be electrically connected to the circuit board 311 via a cable.

[0058] In this embodiment, the rolling cavity 12 is configured as a relatively independent structure. Preferably, the rolling cavity 12 is a closed structure, which prevents fluids or air from other cavities from entering the rolling cavity 12. This avoids external media from interfering with the magnetic rolling element 32 and ensures the rolling of the magnetic rolling element 32, especially random rolling.

[0059] In other embodiments, the rolling cavity 12 may also be a semi-closed structure, with a through hole or opening on the inner shell 15. The through hole or opening is smaller than the magnetic rolling element 32 to prevent the magnetic rolling element 32 from coming out of the rolling cavity 12.

[0060] Please refer to Figure 3 In this embodiment, the inner shell 15 includes a first inner shell 151 and a second inner shell 152. The first inner shell 151 has a bowl-shaped structure, and the second inner shell 152 has a lid-shaped structure. The first inner shell 151 and the second inner shell 152 can be fixed by means of screw connection, snap-fit, adhesive, etc. The first inner shell 151 and the second inner shell 152 form a rolling cavity 12. One or both of the first inner shell 151 and the second inner shell 152 can be fixedly connected to the inner wall of the outer shell 14 by means of screw connection, snap-fit, adhesive, etc. The first inner shell 151 forms the base of the rolling cavity 12.

[0061] The second inner shell 152 is located at the upper end of the first inner shell 151, so that the magnetic rolling element 32 rolls inside the first inner shell 151. The first inner shell 151 has a bowl-shaped structure and has enough space inside to set the bottom surface of the concave structure. The first inner shell 151 has a concave surface.

[0062] The magnetic rolling element 32 is a magnetic block, which can be driven to roll by a magnetic field. Preferably, the magnetic rolling element 32 has a ball bearing structure. This ball bearing structure allows the magnetic rolling element 32 to roll in any direction, providing greater rolling freedom and enabling more random motion, thereby achieving more random oscillation of the object 2 to be driven.

[0063] In other embodiments, the magnetic rolling element 32 can also be of other structures, such as cylindrical, rugby ball-shaped, etc. Under the action of a magnetic field, it can also be driven to roll randomly, thereby driving the object 2 to be driven to swing randomly.

[0064] In this embodiment, the magnetic follower 33 is installed at the lower end of the connecting part 22 of the object to be driven 2, and the magnetic follower 33 is located in the lower part of the first mounting cavity 111. The magnetic follower 33 can be a sheet-like, block-like, or spherical structure, and can be of any shape. The magnetic follower 33 is in a suspended installation state, and there is a certain magnetic attraction or repulsion between the magnetic follower 33 and the magnetic rolling element 32. The random rolling of the magnetic rolling element 32 can drive the magnetic follower 33 to swing randomly. The magnetic follower 33 and the flame part 21 are located at both ends of the connecting part 22. After the magnetic follower 33 is driven to swing randomly, it drives the flame part 21 to swing randomly in the opposite direction. The magnetic follower 33 has a certain weight, so that when the magnetic follower 33 is in a stationary state, the flame part 21 can be kept in a stable state without swinging, which can meet the usage requirements of certain scenarios.

[0065] In this embodiment, the random drive device further includes a light source 6, and the mounting cavity 11 further includes a third mounting cavity 113, in which the light source 6 is mounted. The light source 6 can be an LED light source or other light-emitting light source, and can be a fixed color light source or a color-changing light source.

[0066] The third mounting cavity 113 is disposed adjacent to the first mounting cavity 111, and a light-transmitting wall, such as a transparent window, is provided between them. This allows the light emitted by the light source 6 in the third mounting cavity 113 to illuminate the flame part 21 in the first mounting cavity 111, making the flame part 21 appear to emit light, thus simulating a candle flame. A light-transmitting hole may also be provided between the third mounting cavity 113 and the first mounting cavity 111, so that the light emitted by the light source 6 can also illuminate the flame part 21 in the first mounting cavity 111.

[0067] Installing the light source 6 on the outside of the first mounting cavity 111 simplifies and reduces the size of the first mounting cavity 111, making it easier to inject liquid and seal the first mounting cavity 111. If there is a liquid medium in the first mounting cavity 111, the light source 6 can be isolated from the liquid medium, forming an isolation protection for the light source 6 and avoiding the risk of short circuits and other failures.

[0068] The light source 6 can directly send light to the flame part 21, or the light source 6 can send light to the flame part 21 through a reflector. Both methods can illuminate the flame part 21 to simulate the flame part 21 emitting light, and thus simulate the burning of a candle.

[0069] In other embodiments, the light source 6 may also be installed inside the first mounting cavity 111, and the outer side of the light source 6 may be provided with a waterproof structure such as a transparent cover, which can also isolate and protect the light source 6.

[0070] In other embodiments, the light source 6 may not be provided. Instead, LED beads or other light-emitting bodies may be provided on both sides of the flame section 21. For example, flexible circuit boards or flexible circuit strips may be provided on both sides of the flame section 21, and light-emitting beads may be assembled on the flexible circuit boards or flexible circuit strips. This can also achieve the illumination of the flame section 21 to simulate the burning of a candle.

[0071] In this embodiment, the random drive component 3 of the random drive device includes an electromagnetic drive 31, a magnetic rolling element 32, and a magnetic follower 33. The electromagnetic drive 31 can generate a magnetic field to drive the magnetic rolling element 32 to roll. There is a magnetic attraction or repulsion between the magnetic rolling element 32 and the magnetic follower 33. When the magnetic rolling element 32 moves, it will drive the magnetic follower 33 to move together through magnetic force. The magnetic follower 33 is installed together with the object to be driven 2, thereby driving the object to be driven 2 to swing. Since the magnetic rolling element 32 rolls in the rolling cavity, its motion has a high degree of freedom and high randomness, which makes it possible to drive the object to be driven 2 to swing more randomly, improve the realism of the motion of the object to be driven 2, and enhance the viewing experience of the object to be driven.

[0072] In one embodiment, the bottom surface 153 of the rolling cavity 12 may include at least one of a curved surface, a plane, and an inclined surface. For example, the bottom surface 153 of the rolling cavity 12 is concave. The concave surface may be formed by an inwardly concave curved surface, or it may be formed by multiple inclined surfaces, or it may be formed by both curved surfaces and inclined surfaces. Under the action of gravity, the magnetic rolling element 32 will roll on the bottom surface 153 of the rolling cavity 12. When the bottom surface 153 of the rolling cavity 12 is concave, the gravity of the magnetic rolling element 32 can provide the inertial force for the rolling of the magnetic rolling element 32, which can further improve the randomness of the rolling of the magnetic rolling element 32.

[0073] The bottom surface 153 of the rolling cavity 12 can also be a plane or an inclined plane. The magnetic rolling element 32 can also achieve radial or near-radial rolling in the plane or inclined plane to drive the object 2 to swing randomly.

[0074] In one embodiment, the first inner shell 151 (the base of the rolling cavity 12) can be a flexible structure, and the bottom surface 153 of the rolling cavity 12 is a concave surface. This concave surface is a flexible structure; for example, the first inner shell 151 is made of elastic silicone. Alternatively, the first inner shell 151 may have a flexible layer forming the concave surface, meaning the concave surface of the rolling cavity 12 is a flexible structure. With this configuration, when the magnetic rolling element 32 rolls within the concave surface of the first inner shell 151, the concave surface of the flexible structure can absorb the impact of the magnetic rolling element 32, thus reducing shock and noise and optimizing the user experience.

[0075] In one embodiment, the concave surface at the bottom of the first inner shell 151 is preferably a concave spherical structure. This configuration allows the magnetic rolling element 32 to roll in any direction on the concave surface, further improving the randomness of the rolling.

[0076] In one embodiment, the bottom surface of the rolling cavity 12 is concave, and the lowest point of the bottom surface of the rolling cavity 12 is located in the middle of the bottom surface. This arrangement ensures that after the magnetic rolling element 32 loses its electromagnetic drive, it will eventually stop at the lowest point of the bottom surface of the rolling cavity 12, that is, it will eventually stop at the middle of the bottom surface of the rolling cavity 12. This allows the object to be driven 2 to be in a vertical state, thus ensuring the aesthetics of the device when it is not in use.

[0077] Please refer to Figure 1 and Figure 2 In one embodiment, a connector 13 is provided on the top outer side of the housing 1. The connector 13 is used to suspend the random drive device on the inverted lamp holder. The connector 13 may have a threaded connection structure, and the connector 13 also has an electrical contact point, which can be electrically connected to the circuit board 311 through a cable or other structure. When the connector 13 is connected to the lamp holder, both physical and electrical connections can be achieved. This random drive device can be installed on a ceiling or wall.

[0078] In one embodiment, the connector 13 may also be provided with a physical connection structure such as a snap-fit ​​structure or a magnetic structure to fix the connector 13 to the lamp holder.

[0079] In one embodiment, the first mounting cavity 111 within the housing 1 is a liquid medium cavity. The liquid medium cavity is a sealed cavity filled with a liquid medium, preferably a liquid medium with good light transmittance to provide better illumination, especially to better mimic the lighting of a natural candle. For example, the liquid medium can include, but is not limited to, colorless water or colorless liquids such as silicone oil. The liquid medium can also be colored to meet the needs of special colored light illumination; for example, the liquid medium can be red or yellow to provide red or yellow light illumination. Phosphorescent powder or other substances can also be added to the liquid medium to enhance the illumination effect and meet the needs of different users.

[0080] The liquid medium cavity can be filled with liquid medium, which can prevent the formation of air bubbles in the liquid medium cavity and affect the lighting effect.

[0081] The object to be driven 2 is located in a liquid medium. The liquid medium not only allows the object to be driven 2 to float and sway, but also causes the liquid medium to move after being swayed and swayed by the object to be driven 2. In this process, a dynamic liquid medium is formed. The dynamic liquid medium can generate light spots. When the light spots are located on the object to be driven 2, the simulation of the object to be driven 2 can be further improved.

[0082] In other embodiments, an antifreeze agent may also be mixed into the liquid medium so that the random drive device can be used in cold regions and the liquid medium can be prevented from freezing.

[0083] The housing 1 may be provided with multiple structural components to form a liquid medium cavity, such as a cover plate, to achieve sealing and fixation after the liquid medium is filled into the liquid medium cavity. The housing 1 may also be provided with a liquid injection hole, through which the liquid medium is injected into the liquid medium cavity, and then the liquid injection hole is sealed by a sealing plug or sealant.

[0084] In this embodiment, the object to be driven 2 is installed inside the liquid medium cavity, and the object to be driven 2 is a flexible structure. Specifically, the flame part 21 of the object to be driven 2 is a flexible structure. The flame part 21 can be a sheet-like structure such as a metal sheet or a plastic sheet, or it can be a thin film structure such as tin foil, with several reinforcing strips provided on the thin film structure to maintain a certain rigidity of the flame part 21.

[0085] In this embodiment, the random drive component 3 is installed inside the second mounting cavity 112, that is, the random drive component 3 is installed outside the liquid medium cavity. This allows the liquid medium cavity to have a smaller spatial structure to meet the installation of the object to be driven 2, reducing the complexity of the liquid medium cavity. This is beneficial for the miniaturization and simplification of the liquid medium cavity, reducing the amount of liquid medium filling, and facilitating installation and sealing. At the same time, the random drive component 3 requires electric drive when it is working. Isolating the random drive component 3 from the liquid medium can avoid the risk of short circuits and other failures in the random drive component 3.

[0086] In other embodiments, the random drive component 3 may also be installed in other cavities or partially located on the outside of the housing 1, or the random drive component 3 may be installed on the outside of the liquid medium cavity to achieve isolation between the random drive component 3 and the liquid medium.

[0087] In other embodiments, the random drive component 3, either entirely or partially, can also be installed inside the liquid medium cavity. For example, the random drive component 3 can be a mechanical drive mechanism, with the transmission arm of the random drive component 3 or the entire random drive component 3 located inside the liquid medium cavity and connected to the connecting part 22, which can also drive the object 2 to be driven.

[0088] In this embodiment, the object to be driven 2 is oscillatingly mounted inside the liquid medium cavity. The object to be driven 2 can be oscillatingly connected to the housing 1 through the connecting part 22, similar to the omnidirectional connection between the connecting part 22 and the housing 1. The object to be driven 2 can be set to oscillate within a 360° range, that is, the flame part 21 can oscillate and rotate. With this setting, the reflective surface of the flame part 21 can oscillate to different orientations, such that initially the two reflective surfaces of the flame part 21 face the front and rear sides, and after oscillation, the reflective surfaces of the flame part 21 face the left and right sides. The oscillation setting of the object to be driven 2 allows the object to be driven 2 to oscillate after the random driving component 3 drives the object to be driven 2. The oscillation of the object to be driven 2 can better drive the flexible movement of the flame part 21, more closely resembling the burning and flickering state of a real flame.

[0089] In other embodiments, the object to be driven 2 can only perform swinging activities. For example, the two reflective surfaces of the flame part 21 are oriented to the front and rear. After subsequent swinging, the two reflective surfaces of the flame part 21 only swing in the pitch state of the front and rear. When the random drive device of this structure emits light in a fixed direction, this structure can also form a good simulation effect.

[0090] In this embodiment, a flexible object to be driven 2 is provided and installed in the liquid medium cavity. The flexible object to be driven 2 is located in the liquid medium. When the object to be driven 2 is driven, the flexible object to be driven 2 will float in the liquid medium in a wave-like manner. The driving of the object to be driven 2 will drive the flow of the liquid medium. The flowing liquid medium will then react on the object to be driven 2, pushing the object to be driven 2 to move. Under the push of the random driving component 3 and the liquid medium, the direction and force of the swing of the flexible object to be driven 2 are more random, which is closer to the flame of a real candle, thus improving the simulation of the flame of this random driving device.

[0091] In one embodiment, please refer to Figure 2 The random drive device also includes a light source 6 and a reflector 7, which are installed in the third mounting cavity 113. The light source 6 can be an LED light source or other light source, and can be a fixed color light source or a color-changing light source.

[0092] The reflector 7 is located in the light path of the light source 6, while the flame simulation component is located at the focal point of the reflection of the reflector 7. The light source 6 indirectly illuminates the object to be driven 2 through the reflector 7. The reflector 7 not only changes the path of the light, allowing the light source 6 to be placed in a more convenient installation position, simplifying and facilitating the installation of the light source 6, but also acts as a light-focusing device, allowing the light emitted by the light source 6 to be focused onto the object to be driven 2, increasing the light concentration on the object to be driven 2. The object to be driven 2 can reflect higher intensity light for external lighting, resulting in better lighting effects.

[0093] The reflector 7 can be set as a spherical mirror or a cylindrical mirror. The reflector 7 can simultaneously illuminate the first and second flame surfaces of the flame simulator, achieving 360-degree or 180-degree illumination of the flame simulator. This allows a single light source 6 to simultaneously illuminate both sides of the flame simulator, resulting in better lighting effects.

[0094] Preferably, the reflector 7 is a spherical mirror, which can illuminate the flame simulation component 360 degrees, so that the object to be driven 2 can be illuminated in any swinging position.

[0095] The third mounting cavity 113 is equipped with a reflector bracket 71, which can be a cylindrical structure. One end or the outer periphery of the reflector bracket 71 is fixedly connected to the housing 1 by means of snap-fit, bonding, interference fit, etc. The reflector 7 is installed at the other end of the reflector bracket 71. The reflector bracket 71 is located between the light source 6 and the reflector 7. The illumination light emitted by the light source 6 passes through the reflector bracket 71 and shines on the reflector 7. The reflector 7 then reflects the illumination light, and the reflected illumination light passes through the reflector bracket 71 and enters the first mounting cavity 111. The reflector bracket 71, located between the light source 6 and the reflector 7, also serves to isolate light, preventing the illumination light emitted by the light source 6 from entering other areas within the third mounting cavity 113. This facilitates the reflector 7 in reflecting and focusing the illumination light emitted by the light source 6 onto the flame part 21 of the object to be driven 2.

[0096] Preferably, the reflector 7 covers and seals one end of the reflector bracket 71, which can further prevent the illumination light emitted by the light source 6 from entering other areas within the third mounting cavity 113, and improve the reflector 7's ability to reflect and concentrate the illumination light emitted by the light source 6 onto the flame section 21.

[0097] In other embodiments, a light source mounting base 61 may be provided within the third mounting cavity 113. The light source 6 is mounted on the light source mounting base 61. The light source mounting base 61 has mounting holes or other mounting structures in its central part. The light source 6 is mounted within the mounting holes or other mounting structures in the central part of the light source mounting base 61. The light source mounting base 61 positions the light source 6 in the central position of the third mounting cavity 113, aligning the light source 6 with the object to be driven 2 along the axial direction of the electronic candle. The light source mounting base 61 can be made of a material with good thermal conductivity, such as aluminum. This configuration improves the heat dissipation of the light source 6, ensuring that the light source 6 operates within a suitable temperature environment and extending the lifespan of the electronic candle.

[0098] In other embodiments, the reflector bracket 71 can also be of other structures. When the volume of the third mounting cavity 113 is relatively small, the reflector bracket 71 can adopt a hollow bracket structure, which can also fix the reflector 7. Furthermore, the light leakage rate of the illumination light emitted by the light source 6 is relatively low. The reflector 7 can also reflect and concentrate most of the illumination light emitted by the light source 6 onto the flame part 21, thereby improving the external illumination brightness of the flame part 21.

[0099] In this embodiment, the reflector 7 is a concave reflector. The concave spherical mirror has a light-concentrating function, which can focus the illumination light emitted by the light source 6 and then irradiate the flame part 21, thereby increasing the concentration of light on the flame part 21. The reflector 7 has a concave reflective surface formed by electroplating, sputtering, or other methods to improve the reflectivity of the reflector 7.

[0100] The object to be driven 2 is located at the focal point of the light path emitting the illumination light from the reflector 7. Preferably, the middle position of the flame 21 is located at the focal point of the light path emitting the illumination light from the reflector 7, which maximizes the concentration of the illumination light emitted by the light source 6 onto the flame 21, thereby increasing the brightness of the flame 21's external illumination. Of course, other positions of the flame 21 located at the focal point of the light path emitting the illumination light from the reflector 7 can also concentrate the illumination light emitted by the light source 6 onto the flame 21, thereby increasing the brightness of the flame 21's external illumination.

[0101] In this embodiment, the reflector 7 is preferably a concave spherical mirror. The concave spherical mirror structure can illuminate the flame part 21 from the light source 6 in a 360° direction. Not only can the light be simultaneously illuminated on the flame part 21, but it can also ensure that the light is simultaneously illuminated on the flame part 21 at any position after it swings and rotates. This configuration not only ensures that the flame part 21 is illuminated from both sides, but also works in conjunction with the rotation and swing of the flame part 21, resulting in higher simulation accuracy.

[0102] In other embodiments, the reflector 7 can also be a concave curved mirror with a cylindrical surface structure. This curved mirror can direct the illumination light emitted by the light source 6 from a 180° direction onto the flame section 21. When the central axis of the curved mirror is located on the central surface of the flame section 21 (the surface between the two surfaces of the flame section 21), the curved mirror can simultaneously illuminate the reflective surface of the flame section 21 with the illumination light emitted by the light source 6. In this structure, the flame section 21 is relatively fixed and can swing, but cannot rotate along the axial direction, thus ensuring concentrated illumination from both sides of the flame section 21.

[0103] In this embodiment, the flame section 21, the light source 6, and the reflector 7 are arranged vertically and aligned along a central axis. The light source 6 is located between the flame section 21 and the reflector 7, avoiding the reflection focal point of the reflector 7, while the flame section 21 is positioned at the reflection focal point of the reflector 7. With this arrangement, the reflector 7 can reflect almost all the illumination light from the light source 6 onto the flame section 21, improving the concentration of light received by the flame section 21.

[0104] In other embodiments, the flame section 21, the light source 6, and the reflector 7 can also be slightly offset and aligned on a central axis, which can also improve the concentration of light received by the flame section 21.

[0105] In this embodiment, since the random drive device for concentrated light is equipped with a reflector 7, the light source 6 does not directly emit illumination light onto the flame part 21, but indirectly illuminates the flame part 21 through the reflection of the reflector 7. The reflector 7 can not only change the illumination path of the illumination light, but also play a concentrating role, so that the light emitted by the light source 6 is focused onto the flame part 21, thereby increasing the concentration of light received by the flame part 21. The flame part 21 can reflect higher intensity light for external illumination, resulting in a better lighting effect.

[0106] In other embodiments, the flame section 21, the light source 6, and the reflector 7 can also be installed in the same cavity. The reflector 7 can also focus and reflect the illumination light emitted by the light source 6 onto the flame section 21, thereby increasing the external illumination brightness of the flame section 21.

[0107] In one embodiment, a random drive device is provided, which can be used to drive the object 2 to be driven located outside the housing 1 to swing.

[0108] Please refer to Figure 5 In this embodiment, the mounting base 4 is disposed on the outside of the housing 1, or the mounting base 4 is installed in the inner cavity of the housing 1, and a portion of the mounting base 4 is exposed on the outside of the housing 1.

[0109] The object to be driven 2 is mounted on the outside of the housing 1 via the mounting base 4, with the object exposed on the outside for display. For example, the object to be driven 2 can be a large flame piece of wood. The housing 1 is shaped like a pile of wood, or the outer side of the housing 1 is covered with an outer layer of wood. The object to be driven 2 is mounted on the outside of the housing 1 and is located on top of the pile of wood. The object to be driven 2 is connected to the magnetic follower 33 of the random drive component 3, and the magnetic follower 33 drives the object to be driven 2 (large flame piece) to swing randomly.

[0110] The random drive device in this embodiment can simulate the burning of a wood pile. By driving the exposed large flame piece to swing through the random drive component 3, the randomness of the swing of the large flame piece is increased, making the swing of the large flame piece more realistic and improving the viewing experience.

[0111] In one embodiment, the random drive device can be used to drive other objects 2 to be driven located outside the housing 1 to swing.

[0112] Please refer to Figure 6 The random drive device is installed at the bottom of the fish tank 8. The object to be driven, 2, is a moving part such as aquatic plants. The object to be driven, 2, is installed at the bottom of the water tank 81 of the fish tank 8 and is located outside the random drive assembly 3. The random drive assembly 3 is installed in the mounting box 82 at the bottom of the fish tank 8. The magnetic follower 33 of the random drive assembly 3 is connected to the object to be driven, 2, via a connecting member such as a steel wire. The connecting member extends from the water tank 81 into the mounting box 82. The connection point is waterproofed, for example, by passing through a sealing ring.

[0113] In this structure, the object to be driven 2 located in the aquarium pool 81 is connected to the magnetic follower 33 of the random drive component 3 of the bottom mounting box 82. The magnetic follower 33 drives the object to be driven 2 to float and swing in the aquarium, increasing the randomness of the swing of the object to be driven 2, making the swaying of moving parts such as aquatic plants more realistic and improving the viewing experience.

Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
