Description

Technical Field

[0001] This utility model relates to the field of mechanism transmission technology, and in particular to a forward and reverse rotating mechanism and a landscape light. Background Technology

[0002] Gear transmission is a common mechanical transmission method that uses the meshing of gears to transmit power between different shafts. Traditional mechanical gear mechanisms often have complex structures, requiring a large number of parts and components, which directly leads to a significant increase in manufacturing costs and assembly difficulty, resulting in complex maintenance and an increased risk of system failure. Furthermore, traditional gear mechanisms require a large amount of electricity or energy input to maintain operation, which not only increases operating costs but also limits portability and availability.

[0003] In summary, traditional gear rotation mechanisms suffer from technical problems such as complex structure, high cost, and high energy consumption, but have significant room for development. Utility Model Content

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The technical features designed in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0044] In the description of this utility model, it should be noted that all terms used in this utility model (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains, and should not be construed as limiting this utility model; it should be further understood that the terms used in this utility model should be understood to have the same meaning as those in the context of this specification and in the relevant field, and should not be understood in an idealized or overly formal sense, except as expressly defined in this utility model.

[0045] It should be noted that the terms "forward rotation" and "reverse rotation" mentioned in this utility model refer to the two rotation directions being opposite. For example, when "forward rotation" is clockwise, "reverse rotation" is counterclockwise; when "forward rotation" is counterclockwise, "reverse rotation" is clockwise.

[0046] This utility model provides a forward and reverse rotating mechanism comprising: a frame 10; a drive mechanism 20 fixedly connected to the frame 10; a rotating shaft 30 connected to the drive mechanism 20; a first gear 40 and a second gear 50 fixedly connected to the rotating shaft 30 along the axial direction; an external gear disk 60 that meshes externally with the first gear 40; and an internal gear disk 70 that meshes internally with the second gear 50.

[0047] In specific implementation, such as Figure 1As shown, the drive mechanism 20 is fixedly connected to the frame 10, and the rotating shaft 30 is connected to the drive mechanism 20 to drive the rotating shaft 30 to rotate. Preferably, the connection between the drive mechanism 20 and the frame 10 and the rotating shaft 30 can be detachable or non-detachable. The rotating shaft 30 is axially fixedly connected from top to bottom to a first gear 40 and a second gear 50. Preferably, the first gear 40 and the second gear 50 can be configured as spur gears, helical gears, bevel gears, or worm gears, respectively, depending on the specific requirements. The external gear disk 60 meshes externally with the first gear 40 to drive the external gear disk 60 to rotate forward; the internal gear disk 70 meshes internally with the second gear 50 to drive the internal gear disk 70 to rotate in reverse. Preferably, the relative positions of the axes of the two meshing gears can be parallel axes, intersecting axes, or staggered axes; this embodiment is not limited to these.

[0048] Preferably, the drive mechanism 20 includes a power source 21 and a transmission assembly 22. The power source 21 is connected to the rotating shaft 30 via the transmission assembly 22 to drive the rotating shaft 30 to rotate. The power source 21 is a motor or electric motor.

[0049] Preferably, the transmission component 22 is one or more of a cam component, a connecting rod component, a gear component, and a helical component.

[0050] In specific implementation, such as Figure 1 , 3 As shown, the power source 21 is configured as a variable speed motor, and the transmission assembly 22 is configured as a gear assembly. The power source 21 is connected to the rotating shaft 30 through the transmission assembly 22, enabling the drive mechanism 20 to effectively transmit power, thereby achieving the rotation of the rotating shaft 30. This, in turn, drives the first gear 40 and the second gear 50, which are fixedly connected to the rotating shaft 30, to rotate in the same direction as the rotating shaft 30. The first gear 40 forms an external mesh with the external gear disk 60, that is, the first gear 40 drives the external gear disk 60 to rotate in the opposite direction to the rotation direction of the first gear 40. The second gear 50 forms an internal mesh with the internal gear disk 70, that is, the second gear 50 drives the internal gear disk 70 to rotate in the same direction as the rotation direction of the second gear 50, thereby achieving a forward and reverse rotation effect.

[0051] Preferably, the frame 10 has a mounting portion 11 and a first shaft portion 12 and a second shaft portion 13 disposed at opposite ends of the mounting portion 11; the mounting portion 11 is used to mount the power source 21; the external gear disk 60 is sleeved on the first shaft portion 12 through a first bearing, and the internal gear disk 70 is sleeved on the second shaft portion 13 through a second bearing.

[0052] In specific implementation, such asFigure 5 As shown, the first shaft portion 12 and the second shaft portion 13 are located at both ends of the mounting portion 11. Both the first shaft portion 12 and the second shaft portion 13 are hollow cylinders that are interconnected to accommodate the wiring for supplying power to the drive mechanism 20. The first shaft portion 12 and the second shaft portion 13 are respectively provided with a first bearing and a second bearing. Preferably, the first bearing and the second bearing can be deep groove ball bearings, roller bearings, sliding sleeve bearings, or other suitable bearing structures, and this embodiment is not limited to these. The external gear disk 60 is sleeved on the first shaft portion 12 via the first bearing, and the internal gear disk 70 is sleeved on the second shaft portion 13 via the second bearing. The first bearing and the second bearing respectively support the external gear disk 60 and the internal gear disk 70 on the shaft to ensure that they can rotate and remain in their original horizontal position without sliding up and down; at the same time, the bearings enable the external gear disk 60 and the internal gear disk 70 to rotate more smoothly, ensuring the stability of the forward and reverse rotation mechanism.

[0053] Furthermore, the first shaft portion 12 has an external thread at one end away from the mounting portion 11, and the second shaft portion 13 has an internal thread at one end away from the mounting portion 11, to facilitate the installation of the forward and reverse rotation mechanism. More preferably, the forward and reverse rotation mechanism also includes a housing (not shown in the figure) to detachably house the drive mechanism, gears, and other parts within the housing, thereby preventing interference from external environmental factors such as dust and moisture.

[0054] Preferably, the transmission assembly 22 includes a drive gear 22a and a crown gear 22b meshing with the drive gear 22a. The drive gear 22a is fixedly connected to the output shaft of the power source 21. The crown gear 22b is fixedly connected to the rotating shaft 30 along the axial direction. The output shaft of the power source 21 drives the rotating shaft 30 to rotate through the meshing of the drive gear 22a and the crown gear 22b.

[0055] Furthermore, such as Figure 2 , 4 As shown, it also includes a shaft fixing seat 80 fixedly connected to the mounting part 11. The shaft fixing seat 80 includes an opening 81 and a bearing mounting part 82 that extends symmetrically from the opening 81 to one side of the rotating shaft. The rotating shaft 30 is rotatably mounted on the bearing mounting part 82. An accommodating space E is formed between the opening and the bearing mounting part 82. The crown gear 22b is located on the rotating shaft 30 within the accommodating space E. A through hole is provided in the middle of the opening 81. The drive gear 22a passes through the through hole and meshes with the crown gear 22b within the accommodating space E.

[0056] With the above configuration, the drive mechanism 20 can be installed between the external gear disk and the internal gear disk, and the design of the shaft fixing seat 80 makes the whole structure more compact, which not only saves space but also avoids structural complexity, and can be widely used in various fields.

[0057] Preferably, the central axis of the rotating shaft 30 is parallel to the central axis of the external gear disk 60 and the central axis of the internal gear disk 70, respectively.

[0058] Preferably, the central axis of the external gear disk 60 and the central axis of the internal gear disk 70 may or may not be collinear, and this is not limited here.

[0059] This utility model also provides a landscape light, which adopts the forward and reverse rotating mechanism as described above; it also includes a support frame 1 detachably connected to the frame 10, a forward rotating component 2 fixedly connected to the outer gear disk 60, a reverse rotating component 3 fixedly connected to the inner gear disk, and a lighting device 4 fixedly connected to one or more of the frame 10, support frame 1, forward rotating component 2, and reverse rotating component 3.

[0060] In specific implementation, such as Figure 1 , 6 As shown, the support frame 1 is detachably connected to the frame 10. The external gear disk 60 has an upwardly extending cylindrical tube on its surface opposite to the internal gear disk 70. The cylindrical tube has several through holes distributed circumferentially to install the forward rotating component 2, which rotates in the same direction as the external gear disk 60. The internal gear disk 70 has several through holes distributed circumferentially to install the reverse rotating component 3, which rotates in the same direction as the internal gear disk 70.

[0061] The specific structures of the forward-rotating component 2 and the reverse-rotating component 3 can be designed according to actual working requirements and are not limited here. For example Figure 6 As shown, the forward-rotating component 2 and the reverse-rotating component 3 can be several petals, thus forming a flower-shaped landscape light with the upper petals rotating forward and the lower petals rotating backward. Of course, according to the concept of this invention, those skilled in the art can also apply it to decorative landscape lights that require forward and reverse rotation, such as animal-shaped landscape lights, planet-shaped landscape lights, etc., all of which fall within the protection scope of this utility model.

[0062] The lighting device 4 is fixedly connected to one or more of the frame 10, support frame 1, forward rotating component 2, and reverse rotating component 3. The lighting device 4 can be one or more of the following: light bulb, LED bead, light strip, light bar, and LED. Its specific installation position can be set according to actual needs and is not limited here.

[0063] Preferably, the support frame 1 and / or the frame 10 have internal wiring channels for accommodating lines that supply power to the drive mechanism 20 and / or the lighting device 4.

[0064] In specific implementation, the support frame 1 is a hollow structure that can communicate with the first shaft portion 12 and the second shaft portion 13 of the frame 10 to accommodate the line for supplying power to the drive mechanism 20. This arrangement can neatly install the wires inside the support frame 1 or the frame 10, which helps to protect the wires from mechanical damage, physical damage or adverse effects of the external environment, and reduces the risk of electric shock or short circuit.

[0065] Preferably, the device further includes a solar power generation device 5, which is electrically connected to the drive mechanism 20 and / or the lighting device 4 to supply power to the drive mechanism 20 and / or the lighting device 4.

[0066] Better, such as Figure 6 As shown, the solar power generation device 5 can be installed on the surface of the support frame 1 or on the outside of the support frame 1.

[0067] It should also be noted that the forward and reverse rotation mechanism provided by this utility model is not limited to landscape lighting. According to the inventive concept of this utility model, it can also be applied to other home appliances, digital products, toys, and daily necessities that need to achieve forward and reverse rotation at the same time, and all of them fall within the protection scope of this utility model.

[0068] In summary, compared with the prior art, the forward and reverse rotating mechanism and landscape light provided by this utility model have the following advantages:

[0069] First, the structure is simple, reducing the number of mechanical parts and making the overall design simpler and more compact;

[0070] Second, only one power source and corresponding gear transmission system are needed to achieve forward and reverse rotation, avoiding the waste of multiple independent power sources and saving energy.

[0071] Third, the frame is designed as a hollow structure to accommodate the power supply lines to the drive mechanism, protecting the circuit from interference from external factors and helping to extend the product life.

[0072] IV. The landscape lights are powered by solar power generation devices, which are environmentally friendly, stable, and highly safe.
