Description

Technical Field

[0001] This application relates to the field of mechanical transmission, and more particularly to the field of solar energy equipment technology, specifically to a transmission component, a solar energy bracket, and a solar energy device. Background Technology

[0002] Mechanical transmission refers to the transmission of power provided by a power source through a mechanical structure, thereby driving a load to achieve the desired motion. It typically includes an input component connected to the power source and an output component connected to the load. Currently, mechanical transmission mainly includes two types: one is friction transmission, which transmits power through friction between the input and output components, and the other is meshing transmission, which transmits power or motion through the meshing of the input and output components or with the help of intermediate components.

[0003] In some applications, it is necessary to lift or lower the load to a certain height through a transmission structure, such as elevators. Since the weight of the load driven each time varies greatly, the power source needs to increase its power to ensure that it can drive the maximum load.

[0004] In some application scenarios, it is necessary to drive relatively large loads used outdoors through transmission structures, such as billboards, photovoltaic panels, and solar thermal systems. Due to the influence of air flow, the load may exert a large force on the output components in an instant. In this case, the transmission structure will transmit the external force on the load in the opposite direction to the power source, causing damage or even destruction to the power source. Therefore, either additional mechanical structures such as brakes should be installed, or a transmission structure with a self-locking function should be used.

[0005] Current transmission structures with self-locking functions include combinations of trapezoidal lead screws and lead screw nuts, and combinations of worm gears and worms.

[0006] However, in applications such as those described above, since the trapezoidal lead screw drives the lead screw nut to move along the axial direction of the trapezoidal lead screw, it will interfere with the trapezoidal lead screw when driving the load. Therefore, it is necessary to move the trapezoidal lead screw away from the load to ensure that there is enough space for the load to move.

[0007] When the worm gear teeth and worm shaft teeth transmit power, they rely on tooth meshing, and the contact area is very limited. When the load weight suddenly increases or is subjected to external force instantaneously, the teeth of both are subjected to a large force. After long-term use, gaps are likely to appear between the teeth, resulting in a large error in transmission. Even worse, it can cause damage or even destruction of the worm gear and worm shaft. Invention Overview

[0008] Technical issues

[0009] Therefore, how to design the transmission structure is an urgent problem to be solved when the weight of the load driven varies greatly each time or the load is easily affected by external forces.

[0010] Technical solutions

[0011] This application first proposes a transmission component to solve the problems encountered by the transmission structure when the weight of the load driven each time varies greatly or the load is easily subjected to external forces. This application also proposes a solar panel bracket and a solar device.

[0012] As a first aspect of this application, a transmission assembly is proposed, including...

[0013] Support components;

[0014] The input component is movably connected to the support component;

[0015] An output component is movably connected to the support component, and the output component has an axis defined by the support component. The output component is in a transmission engagement with the input component, and the transmission direction of the input component to the output component is in the same direction as the axis of the output component.

[0016] It also includes a guide structure for guiding the movement of the output component, the guide structure being disposed between the support and the output component and extending in a spiral shape along the axial direction of the output component;

[0017] In use, the output component rotates at least about its axis under the drive of the input component and the guidance of the guide structure.

[0018] Preferably, the angle formed by the guide structure and the axis of the output component is greater than 0 degrees and less than 40 degrees.

[0019] Furthermore, the angle between the guide structure and the axis of the output component is greater than 5 degrees and less than 25 degrees.

[0020] Preferably, the guide structure includes a first guide structure, the first guide structure including a first guide portion and a second guide portion adapted to the first guide portion; the second guide portion is disposed on the support member and / or the input member.

[0021] Furthermore, there is at least one set of the first guide structure, and multiple sets of the first guide structures are arranged at intervals, and all sets of the first guide structures are located on the same circumferential surface, and the center of the circumferential surface is located on the axis of the output component.

[0022] Furthermore, the first guide structure also includes a first movable member, and the first guide portion and the second guide portion are guided together by the first movable member.

[0023] Furthermore, the first movable member is spherical in shape, or the first movable member is cylindrical in shape.

[0024] Furthermore, the transmission assembly proposed in this application also includes an intermediate component, on which the first guide portion is disposed;

[0025] Meanwhile, the guiding structure proposed in this application also includes a second guiding structure, which includes a third guiding part disposed on the intermediate part and the output part, and a fourth guiding part that forms a guiding cooperation with the third guiding part;

[0026] The output component is connected to the input component via the intermediate component.

[0027] Furthermore, at least one of the first guide structure and the second guide structure is spiral-shaped.

[0028] Furthermore, the second guide structure also includes a second movable element.

[0029] Furthermore, the second movable component is spherical, or the second movable component is a roller.

[0030] As a second aspect of this application, a solar panel support includes the transmission assembly described above.

[0031] As a third aspect of this application, a solar energy device includes the solar energy support as described above.

[0032] Beneficial effects

[0033] The transmission component, solar panel bracket, and solar energy device proposed in this application have the following advantages: they ensure the stability and reliability of the transmission, have a long service life, and significantly reduce the power requirements of the power source. Specifically, this is reflected in:

[0034] First, the output component has an axis defined by the support component, meaning the output component can only move around the axis; the direction of transmission of the input component to the output component is the same as the axis of the output component, meaning the component directly driven by the input component will move at least along the axis of the output component; by setting the guide structure in a spiral shape, the output component, driven by the input component and guided by the guide structure, can rotate at least around its axis, thereby driving the load to move through the rotation of the output component around its axis. Therefore, the transmission component proposed in this application has the characteristics of stability and reliability.

[0035] Secondly, since the load's movement is driven by the output component rotating around its axis, when the load's weight changes or when the load is subjected to external forces, the force exerted by the load on the output component is first borne by the guide structure and directly transmitted to the support component, avoiding direct impact on the input component, i.e., avoiding impact on the power source. Simultaneously, when the angle between the helical extension direction of the guide structure and the axis of the output component is greater than 0 and less than 40 degrees, especially when the angle is greater than 5 and less than 25 degrees, when using the transmission assembly proposed in this application, the force exerted by the load on the output component is transmitted to the support structure through the guide structure, thus significantly reducing the force transmitted to the input component, i.e., significantly reducing the force transmitted to the power source. Correspondingly, due to the reciprocity of forces, when it is necessary to drive the input component through the power source, and then have the input component drive the output component to achieve the same load movement, only a smaller power motor is required. Clearly, when the angle between the helical extension direction of the guide structure and the axis of the output component is greater than 0 and less than 40 degrees, not only is the stability and reliability of the transmission assembly further guaranteed, but the power requirements of the power source are also reduced.

[0036] Third, compared with the trapezoidal lead screw, the transmission component proposed in this application will not cause interference during load movement. At the same time, compared with the worm gear, the transmission component proposed in this application has a larger contact area due to the guide structure. This means that when driving the same load or when the load is subjected to instantaneous force, the force per unit area of ​​the contact part of the guide structure is smaller, even when the force transmitted from the output component to the input component is the same. Therefore, this further ensures the transmission stability and reliability of the transmission component while extending its service life.

[0037] Fourth, when the angle between the spiral extension direction of the guide structure and the axis of the output component is greater than 0 and less than 40 degrees, in response to the action of the input component on the output component, without an intermediate component, the distance the load is moved by rotating the output component is less than the distance the load is moved by moving the output component along its axis. Furthermore, the smaller the angle, the larger the reduction ratio and the better the reduction effect, thus requiring less power from the power source. It should be understood that even with an intermediate component, a reduction effect is still achieved. In this case, the comparison should be between the distance the load is moved by rotating the output component and the distance the load is moved along the axis of the output component by the component that forms a direct transmission connection with the input component.

[0055] Embodiments of the present invention

[0056] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It is understood that, without conflict, some technical means of the various embodiments described herein can be substituted for or combined with each other.

[0057] In the description of this application, the terms "first," "second," etc., are used only to distinguish the described objects and have no sequential or technical meaning. Therefore, objects specified with "first," "second," etc., may explicitly or implicitly include one or more of those objects. Furthermore, the words "one" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one, while "multiple" indicates at least two.

[0058] In the description of this application, the terms "connection," "support," "installation," "fixation," "contact," "support," and "reception," etc., should be interpreted broadly. For example, "connection" can be a split connection or a single-piece connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a non-detachable connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can also refer to the internal communication of two components or the interaction between two components. As another example, "support" can be direct support or indirect support through an intermediate medium. Furthermore, "reception" does not necessarily mean complete containment of the entire component; this concept also includes the containment of a portion protruding from the outside. Those skilled in the art can understand the specific meaning of the aforementioned terms in this application according to the specific circumstances.

[0059] In the description of this application, if there are terms such as "A is connected to B in a rotatable manner", it means that A and B are directly or indirectly connected, and A is able to rotate relative to B.

[0060] In the description of this application, references to "one embodiment" or "some embodiments" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0061] As a first aspect of this embodiment, a transmission assembly is proposed. It should be understood that transmission refers to the power transmission between machines. Therefore, the transmission assembly should be understood as a combination of two or more components that, through cooperation, can transmit power.

[0062] like Figures 1 to 8 As shown, the transmission assembly proposed in this embodiment includes a support member 2, an input member 3, and an output member 1.

[0063] In this context, support member 2 refers to a component that can be fixedly connected to the external transmission assembly and can support input member 3 and output member 1. It should be understood that the external component fixedly connected to support member 2 varies depending on the method of using the transmission assembly proposed in this embodiment. For example, in a solar energy device that can track the sun, the solar panel is the final load. To track sunlight, the solar panel needs to rotate relative to the ground. When the output member 1 directly drives the solar panel, support member 2 should be fixedly connected to the ground. In some application scenarios, output member 1 can also be fixedly connected to the ground. In this case, the solar panel is fixedly connected to support member 2, which also enables the solar panel to rotate relative to the ground. Therefore, when the function of a component is the same as that of the component in this application, changing the component name only by changing the usage method should be understood as being within the scope of protection of this application.

[0064] Input component 3 refers to the component in the transmission assembly that is connected to the power source 7. In this embodiment, input component 3 is also movably connected to the support component 2. The movable connection between input component 3 and support component 2 can be a direct contact connection or a connection formed by other components. It should be understood that the movable connection between input component 3 and support component 2 means that the two are not only connected, but input component 3 can also move relative to support component 2. The movement of input component 3 relative to support component 2 includes rotation, linear sliding, or linear sliding while rotating. Meanwhile, power source 7 refers to a mechanical device capable of outputting power, such as an electrically driven motor, a cylinder driven by compressed air, or a hydraulic cylinder driven by liquid.

[0065] It should be noted that input component 3 is connected to power source 7, which can be used as follows: Figure 7 , Figure 8 The transmission connection shown is formed by tooth meshing, but it can also be formed by other existing known transmission methods. For example, the power source 7 and the input component 3 can be connected by a synchronous belt and pulley, or the power source 7 and the input component 3 can be connected by a lead screw and lead screw nut, or the power source 7 can be directly integrated with the input component 3, such as directly selecting a hollow motor or linear motor as the power source 7 as the input component 3. Therefore, changing only the connection relationship between the power source 7 and the input component 3 should be understood as being within the scope of protection of this application.

[0066] Output component 1 refers to a component used to drive the load to move. In this embodiment, output component 1 is also movably connected to the support component 2, and output component 1 has an axis defined by the support component 2. Output component 1 is in transmission cooperation with input component 3, and the transmission direction of input component 3 to output component 1 is in the same direction as the axis of output component 1.

[0067] At the same time, such as Figures 1 to 8 As shown, the transmission assembly proposed in this embodiment also includes a guide structure 5 for guiding the movement of the output component 1. The guide structure 5 is disposed between the support component 2 and the output component 1 and extends in a spiral shape along the axial direction of the output component 1.

[0068] Based on the above, it is clear that when using the transmission component proposed in this embodiment, the power source 7 drives the input component 3, which in turn drives the output component 1. At the same time, under the guidance of the guide structure 5, the output component 1 rotates at least around its axis. In this case, the output component 1 can also drive the final load to rotate around its axis.

[0069] Furthermore, in this embodiment, since the guide structure 5 forces the output component 1 to rotate when it is driven by the input component 3, the smaller the angle between the guide structure 5 and the axis of the output component 1, the easier it is for the input component 3 to drive the output component 1 to move along its axis.

[0070] Preferably, the angle between the axis of the guide structure 5 and the axis of the output component 1 is greater than 0 and less than 40 degrees.

[0071] Ideally, the angle between the axis of the guide structure 5 and the axis of the output component 1 is greater than 5 degrees and less than 25 degrees.

[0072] When the diameter of the output component 1 is 50 mm, and the angle formed by the guide structure 5 and the axis of the output component 1 is different, the following data were obtained by combining a finite number of experiments at different angles:

[0073] When the angle is 40 degrees, when a force of 1000 N is applied to the output component 1, the force required to keep the output component 1 stationary is approximately 850 N along the axis of the output component 1; while in order to drive a load of 1000 N, the driving force required to be provided along the axis of the output component 1 is approximately 1200 N.

[0074] When the angle is 28 degrees, when a force of 1000 N is applied to the output component 1, the force required to keep the output component 1 stationary is approximately 500 N along the axis of the output component 1; while in order to drive a load of 1000 N, the driving force required to be provided along the axis of the output component 1 is approximately 680 N.

[0075] When the angle is 18 degrees, when a force of 1000 N is applied to the output component 1, the force required to keep the output component 1 stationary is approximately 310 N along the axis of the output component 1; while in order to drive a load of 1000 N, the driving force required to be provided along the axis of the output component 1 is approximately 450 N.

[0076] When the angle is 14 degrees, when a force of 1000 N is applied to the output component 1, the force required to keep the output component 1 stationary is approximately 230 N along the axis of the output component 1; while in order to drive a load of 1000 N, the driving force required to be provided along the axis of the output component 1 is approximately 320 N.

[0077] When the angle is 10 degrees, when a force of 1000 Newtons is applied to the output component 1, in order to keep the output component 1 stationary, a force of approximately 150 Newtons is required along the axial direction of the output component 1; while in order to drive a load of 1000 Newtons, a driving force of approximately 210 Newtons is required along the axial direction of the output component 1.

[0078] When the angle is 5 degrees, when a force of 1000 Newtons is applied to the output component 1, the force required to keep the output component 1 stationary is approximately 75 Newtons along the axis of the output component 1; while in order to drive a load of 1000 Newtons, the driving force required to be provided along the axis of the output component 1 is approximately 110 Newtons.

[0079] It is clear from the above experimental data that when the angle between the axis of the guide structure 5 and the axis of the output component 1 is smaller, a smaller power source 7 is needed to drive the same weight of load. At the same time, a smaller power source 7 is also needed to keep the output component 1 from moving relative to the support component 2.

[0080] Furthermore, in this embodiment, as Figure 1 , Figure 2 , Figure 6 As shown, the guide structure 5 includes a first guide structure 51, which includes a first guide portion 511 and a second guide portion 512 adapted to the first guide portion 511. The second guide portion 512 is disposed on the support member 2. It should be noted that in this embodiment, it is stated that the second guide portion 512 is disposed on the support member 2. In fact, the second guide portion 512 can also be directly disposed on the input member 3, and the second guide portion 512 is disposed on both the input member 3 and the support member 2.

[0081] Furthermore, in this embodiment, in order to further increase the contact area between the two cooperating parts in the guide structure 5, at least one set of the first guide structure 51 is provided, and multiple sets of the first guide structure 51 are spaced apart, and the multiple sets of the first guide structure 51 are all located on the same circumferential surface, and the center of the circumferential surface is located on the axis of the output component 1.

[0082] Furthermore, in this embodiment, in order to improve transmission efficiency, the first guide structure 51 further includes a first movable member 513. The first guide portion 511 and the second guide portion 512 form a guide engagement through the first movable member 513. By setting the first movable member 513, when the first guide portion 511 moves relative to the second guide portion 512, the friction generated between the two is changed from surface friction to rolling friction.

[0083] Furthermore, in this embodiment, the first movable member 513 is spherical. It should be understood that when the first movable member 513 is spherical, preferably, a circulation hole can be provided inside the component providing the first guide portion 511 or the component providing the second guide portion 512. The two ends of the circulation hole are respectively connected to the two ends of the first guide portion 511 or the second guide portion 512. When the first guide portion 511 moves relative to the second guide portion 512, the spherical first movable member 513 can roll along the annular circulation path formed by the first guide portion 511 or the second guide portion 512 and the circulation hole, thereby reducing the friction between the first guide portion 511 and the second guide portion 512. It should be understood that in this embodiment, the first movable member 513 is described as spherical. In fact, in some embodiments, the first movable member 513 can also be cylindrical, for example, a roller can be used as the first movable member 513.

[0084] As one embodiment of this application, such as Figures 1 to 7 As shown, in order to make the load rotate only around the axis of the output component 1, or to make the range of rotation of the load around the axis of the output component 1 much greater than the distance of movement along the axis of the output component 1, the transmission assembly proposed in this application further includes an intermediate component 4, on which the first guide portion 511 is disposed; at the same time, the guide structure 5 proposed in this application further includes a second guide structure 52, which includes a third guide portion 521 disposed on the intermediate component 4 and a fourth guide portion 522 disposed on the output component 1 that forms a guiding cooperation with the third guide portion 521; the output component 1 is connected to the input component 3 through the intermediate component 4.

[0085] It should be understood that the first guide structure 51 and the second guide structure 52 are combined to form a multi-level guide structure 5. At least one of the multi-level guide structures needs to be spiral-shaped, that is, at least one of the first guide structure 51 and the second guide structure 52 needs to be spiral-shaped, and the other is as parallel as possible to the axis of the output component 1. At this time, when the transmission component proposed in this embodiment is working, the input component 3 drives the intermediate component 4 to move. Under the guidance of the first guide structure 51, the intermediate component 4 moves linearly at least along the axis of the output component 1. At the same time, under the combined action of the first guide structure 51 and the second guide structure 52, the intermediate component 4 will drive the output component 1 to rotate around the axis. And when either the first guide structure 51 or the second guide structure 52 is parallel to the axis of the output component 1, the output component 1 only rotates around its axis.

[0086] Furthermore, in this embodiment, in order to improve transmission efficiency, the second guide structure 52 also includes a second movable member. It should be understood that the way to improve transmission efficiency by setting the second movable member is the same as the way to set the first movable member 513, and will not be described again here.

[0087] Furthermore, in this embodiment, the second movable member is spherical, or the second movable member is a roller. Similarly, when the second movable member is spherical, its function and application can be referred to the first movable member 513, and will not be repeated here.

[0088] As another embodiment of this application, such as Figure 8 As shown, the difference from the previous embodiment is that the previous embodiment described an implementation scheme with intermediate component 4. In fact, intermediate component 4 can also be omitted. It should be understood that in this case, the guide structure 5 only has the first guide structure 51, and the first guide part 511 of the first guide structure 51 is directly disposed on the output component 1. The input component 3 directly drives the output component 1 to move along the axis. Under the action of the guide structure 5, the output component 1 can also rotate around the axis. That is, the output component 1 both rotates around the axis and makes linear motion along the axis.

[0089] Through the above embodiments, it is evident that the transmission component proposed in this application ensures transmission stability and reliability, has a long service life, and significantly reduces the power requirements of the power source 7. Specifically, this is reflected in:

[0090] First, the output component 1 has an axis defined by the support component 2, meaning that the output component 1 can only move around the axis; the direction of transmission of the input component 3 to the output component 1 is the same as the axis of the output component 1, meaning that the component directly driven by the input component 3 will at least move along the axis of the output component 1; by setting the guide structure 5 in a spiral shape, the output component 1 can rotate at least around its axis under the drive of the input component 3 and under the guidance of the guide structure 5, thereby driving the load to move through the rotation of the output component 1 around its axis. Therefore, the transmission component proposed in this application has the characteristics of stability and reliability.

[0091] Secondly, since the load's movement is driven by the output component 1 rotating around its axis, when the load's weight changes or when the load is subjected to external forces, the force exerted by the load on the output component 1 is first borne by the guide structure 5 and directly transmitted to the support component 2, avoiding direct impact on the input component 3, and thus avoiding impact on the power source 7. Simultaneously, when the angle between the helical extension direction of the guide structure 5 and the axis of the output component 1 is greater than 0 and less than 40 degrees, especially when the angle is greater than 5 and less than 25 degrees, when using the transmission assembly proposed in this application, the force exerted by the load on the output component 1 is transmitted through... The force transmitted from the guide structure 5 to the support structure is greatly reduced, thus the force transmitted to the input component 3 is also greatly reduced. Correspondingly, due to the mutual nature of the forces, when the input component 3 needs to be driven by the power source 7, and the output component 1 needs to be driven by the input component 3 to achieve the same load movement, only a smaller power motor is needed. Obviously, when the angle between the spiral extension direction of the guide structure 5 and the axis of the output component 1 is greater than 0 and less than 40 degrees, it not only further ensures the stability and reliability of the transmission component, but also reduces the power requirements of the power source 7.

[0092] Third, compared with the trapezoidal lead screw, the transmission component proposed in this application will not cause interference during load movement. At the same time, compared with the worm gear, the transmission component proposed in this application has a larger contact area due to the guide structure 5. This means that when driving the same load or when the load is subjected to instantaneous force, the force per unit area of ​​the contact part of the guide structure 5 is smaller when the force transmitted from the output component 1 to the input component 3 is the same. Therefore, this further ensures the transmission stability and reliability of the transmission component while also extending its service life.

[0093] Fourth, when the angle between the spiral extension direction of the guide structure 5 and the axis of the output component 1 is greater than 0 and less than 40 degrees, it also has a deceleration effect. Without the intermediate component 4, the distance the load is moved by rotating the output component 1 is less than the distance the load is moved by moving the output component 1 along its axis. The smaller the angle, the greater the deceleration ratio and the better the deceleration effect, thus requiring less power from the power source 7. It should be understood that even with the intermediate component 4, it still has a deceleration effect. In this case, the comparison should be between the distance the load is moved by rotating the output component 1 and the distance the load is moved along the axis of the output component 1 by the component that forms a direct transmission connection with the input component 3.

[0094] It should be understood that the transmission assembly proposed in this application essentially defines the axis of the output component 1 by the support component 2. When the input component 3 transmits a force to the output component 1 to make the output component 1 move linearly along the axis, the output component 1, under the action of the force and the guidance of the spiral guide structure 5, achieves a motion that rotates at least around its axis.

[0095] Therefore, although in the appendix to this application Figures 1 to 8 The diagram shows that the input component 3 and the support component 2 are directly or indirectly fitted onto the output component 1.

[0096] In fact, the input component 3 can also be arranged parallel to the output component 1, or the input component 3 can be arranged coaxially with the output component 1, or the output component 1 can be sleeved on the input component 3. Therefore, without changing the essence of this application, only the positional relationship between the input component 3 and the output component 1 is changed, but the two directly or indirectly constitute a transmission connection, which should be understood as being within the protection scope of this application.

[0097] Meanwhile, the transmission connection between input component 3 and output component 1 can vary depending on their positional relationship; that is, input component 3 and output component 1 can be directly or indirectly connected. Figures 1 to 7 The diagram illustrates the indirect transmission connection between input component 3 and output component 1. Input component 3 has a first transmission thread 61, and intermediate component 4 has a second transmission thread 62 that matches the first transmission thread 61. The transmission connection between input component 3 and output component 1 is achieved through a threaded engagement between the first transmission thread 61 and the second transmission thread 62. Input component 3 drives intermediate component 4, and intermediate component 4, through a second guide structure 52, drives output component 1, thus completing the transmission connection. Figure 8The diagram shows a direct drive connection, where the drive thread that matches the first drive thread 61 is directly set on the output component 1. In this case, the input component 3 directly drives the output component 1. Obviously, in the threaded drive engagement, the input component 3 expects the output component 1 to move linearly along its axis. However, under the action of the guide structure 5, the output component 1 rotates around its axis while moving linearly.

[0098] It should be understood that, although the accompanying drawings of this application only depict a direct transmission connection between the input component 3 and the intermediate component 4 or the output component 1 via a threaded connection, it is clear that other transmission methods are also possible. For example, by providing a worm segment adapted to a worm gear on the intermediate component 4 or the output component 1, and setting the input component 3 as a worm gear, the transmission method from the input component 3 to the output component 1 is a worm gear transmission. Alternatively, by setting the input component 3 as a pulley and connecting it to the intermediate component 4 or the output component 1 via a transmission belt, the transmission method from the input component 3 to the output component 1 is a belt transmission. Therefore, simply changing the transmission method between the input component 3 and the output component 1 should be understood as being within the scope of protection of this application.

[0099] It should also be noted that the movable connection between the output component 1 and the support component 2 can also adopt a different connection method than that shown in the accompanying drawings of this embodiment, and can also achieve the essence of this application. For example, the support component 2 is set as a rod, and the output component 1 is sleeved on the support component 2. Therefore, changing only the movable connection method between the output component 1 and the support component 2 should also be understood as being within the protection scope of this application.

[0100] Furthermore, it should be noted that the guide structure 5 refers to the mechanical component or structure used to control the direction of mechanical movement. It typically includes a track portion and a moving portion. The track portion defines the trajectory and direction of movement of the moving portion. For example, in this application, the first guide portion 511 and the third guide portion 521 can be understood as track portions, while the second guide portion 512 and the fourth guide portion 522 should be understood as moving portions. It should be understood that although this application only describes the use of surface mating to form guidance and the use of moving parts to form guide mating, in reality, many guide structures 5 can be used to achieve the essence of this application. For example, the use of a screw rod and a sliding ring sleeved on the screw rod, or other existing known guide structures 5 that can be configured as spiral parts. Therefore, simply changing the shape or guiding method of the guide structure 5 should also be understood as being within the scope of protection of this application.

[0101] As a second aspect of this embodiment, a solar panel support includes the transmission component described above. It should be noted that when the above-mentioned transmission component is applied to the solar panel support, either only one transmission component can be used, or multiple transmission components can be used. When multiple transmission components are used, multiple power sources 7 can be used, so that each transmission component corresponds to one power source 7 and is independently connected for transmission. Alternatively, other transmission components can be used, and one power source 7 can be used to simultaneously drive and connect multiple transmission components.

[0102] As a third aspect of this embodiment, a solar energy device includes the solar energy support as described above. It should be noted that a solar energy device refers to a device that can realize photothermal conversion or photoelectric conversion, such as photovoltaic power generation, solar water heaters, etc.
