Description

Technical Field

[0001] This utility model relates to the field of energy storage and assist technology, specifically to an energy storage and assist component and a photovoltaic tracking device. Background Technology

[0002] In fields such as industrial manufacturing, mechanical engineering, and transportation, the motion of loads often exhibits periodic characteristics during the driving process. For example, in the reciprocating motion of a cantilever beam around its axis in a cantilever structure, when the center of gravity of the cantilever beam moves downward, it is a force-saving motion; when the center of gravity moves upward, it is a force-consuming motion. Therefore, the cantilever beam repeatedly undergoes alternating force-saving and force-consuming motions during its motion. The mechanical energy released during the force-saving phase is consumed in various forms, leading to energy waste. In recent years, with the development of green energy and efficient transmission technologies, issues related to energy recovery and reuse have become a research hotspot.

[0003] To address these issues, an energy storage and assist component was designed to recover energy through the compression deformation of a spring. However, the spring may shift or twist during deformation, affecting the stability of the energy storage and assist component. This can also cause friction between the spring and the external protective cylinder or between the spring and the internal traction components, thus affecting energy transfer efficiency and the service life of related components. Furthermore, since the shift or twist of the spring affects the stability of the energy storage and assist component, constraining the deformation trajectory of the spring is a problem that urgently needs to be solved. Utility Model Content

[0004] The first objective of this invention is to provide an energy storage assist component to solve the problem of helical springs in existing energy storage assist components. The second objective of this invention is to provide a photovoltaic tracking device.

[0005] The present invention is achieved by the following technical solution:

[0006] As a first aspect of this utility model, an energy storage and assist component includes:

[0007] The housing includes a base;

[0008] A compression spring, wherein the end of the compression spring closer to the base is a fixed end and the end farther from the base is a movable end, and the fixed end is connected to the base;

[0009] A traction component, one end of which passes through the inside of the compression spring and is connected to the movable end, and the other end of which is connected to an external load;

[0010] The retainer includes a slide rod and a movable block. The slide rod is arranged along the length direction of the compression spring, and one end of the slide rod is connected to the base. The movable block has a sliding hole and is sleeved on the slide rod through the sliding hole. The movable block is connected to the movable end of the compression spring, and one end of the traction member is connected to the movable end through the movable block.

[0011] Optionally, a bushing is provided in the sliding hole, and the movable block is slidably connected to the slide rod through the bushing.

[0012] Optionally, there is at least one slide bar, which is located on the outer periphery or inside the compression spring.

[0013] Optionally, the number of slide bars is three, and the three slide bars are arranged in a circular array along the central axis of the compression spring, forming a channel through which the traction member passes.

[0014] Optionally, when there are multiple slide rods, the retainer further includes a fixing block, and the other end of each of the slide rods is connected to the fixing block.

[0015] Optionally, the fixed block is provided with a clearance through hole, which is used to avoid the connection area between one end of the traction member and the movable block.

[0016] Optionally, the movable block has a protrusion on the end face near the compression spring, and the movable end is sleeved on the protrusion.

[0017] Optionally, the housing further includes a protective shell, which is sleeved on the outside of the compression spring and connected to the base.

[0018] Optionally, the movable block is provided with at least one vent hole.

[0019] As a second aspect of this utility model, a photovoltaic tracking device includes the energy storage assist component described above.

[0020] The advantages of this invention are: it increases the stability of the energy storage booster component and extends its service life.

[0021] First, this utility model limits the movement trajectory of the movable end of the compression spring relative to the fixed end by using a retainer, preventing the compression spring from shifting laterally or twisting during compression or extension. The slide bar in the retainer is set along the length direction of the compression spring, thereby limiting the movable end to compress or extend relative to the fixed end along the length direction of the compression spring. This ensures that the compression spring maintains a uniform force distribution under deformation, prevents local stress concentration, improves the consistency and reliability of force transmission, and enhances the stability of the energy storage and assist component.

[0022] Meanwhile, the traction component passes through the inside of the compression spring and connects to the movable end. The traction component drives the compression spring to deform. By setting a retainer, the compression spring is prevented from shifting laterally during compression or extension. Therefore, friction between the compression spring and the traction component can be avoided, which would affect the energy transfer efficiency. It also avoids wear caused by friction between the compression spring and the traction component, thus increasing the service life of the energy storage booster assembly.

[0023] Secondly, the slide bar of this utility model is arranged along the length direction of the compression spring. Under the action of the slide bar, the stability of the compression spring in the length direction is increased, the compression spring is prevented from deforming in a non-perpendicular state, the structural strength of the energy storage and assisting component is increased, and the service life of the energy storage and assisting component is further increased.

[0024] Third, by setting multiple sliding rods, the stability of the cage is increased. When multiple sliding rods are set, the other end of the multiple sliding rods is fixed by fixing blocks to maintain a stable distance between the multiple sliding rods. This avoids the increased friction of the moving block moving on the sliding rod due to deformation of the sliding rod, which would lead to energy loss and affect the working efficiency of the energy storage booster component.

[0046] like Figures 1 to 5 As shown, the first aspect of this embodiment discloses an energy storage and assist component 100, comprising:

[0047] The housing includes a base 11;

[0048] Compression spring 2, wherein the end of the compression spring 2 closer to the base 11 is a fixed end and the end farther away from the base 11 is a movable end, and the fixed end is connected to the base 11;

[0049] The traction component 3 has one end passing through the inside of the compression spring 2 and connected to the movable end, and the other end connected to an external load;

[0050] The retainer 4 includes a slide rod 41 and a movable block 42. The slide rod 41 is arranged along the length direction of the compression spring 2. One end of the slide rod 41 is connected to the base 11. The movable block 42 is provided with a sliding hole 421. The movable block 42 is sleeved on the slide rod 41 through the sliding hole 421. The movable block 42 is connected to the movable end of the compression spring 2. One end of the traction member 3 is connected to the movable end through the movable block 42.

[0051] It should be noted that, in this embodiment, the base 11 is used to support the energy storage and assist component 100, such as... Figures 1 to 3 As shown, the fixed end of the compression spring 2 is connected to the base 11, and one end of the slide rod 41 in the retainer 4 is connected to the base 11. Depending on the installation position of the energy storage and assist component 100, or the change of some of its components, the shape of the base 11 will also change. The change in the shape of the base 11 does not constitute a limitation on this embodiment.

[0052] It should be noted that in this embodiment, the compression spring 2 stores energy through compression deformation under external force, and releases the stored energy during the process of the deformation recovering or decreasing, and has the property of returning to its shape before the external force was applied. Using the compression spring 2 as the component in the energy storage assist assembly 100 to store energy recovered from the external load has the following advantages: the compression spring 2 stores energy through compression deformation, and its volume after deformation is usually larger than other elastic components. Therefore, the installation space requirement for the compression spring 2 is relatively lower, and only space needs to be reserved for the free length of the compression spring 2.

[0053] It should be noted that in this embodiment, the traction member 3 is used to connect the external load and the compression spring 2. If the external load is a simple linear motion, the external load and the compression spring 2 can be connected by adjusting the direction of the traction member 3 through a simple guiding component; or if the external load is a rotational motion around an axis or other motion, then the rotational motion or other motion needs to be converted into linear motion through a transmission component before connecting the compression spring 2 through the traction member 3. Therefore, the traction member 3 can adopt different structures or materials depending on the actual guiding component and transmission component. As long as the function of the traction member 3 is satisfied, changes in the structure or material of the traction member 3 do not constitute a limitation on this embodiment.

[0054] It should be noted that, in this embodiment, the retainer 4 is used to limit the movement trajectory of the movable end of the compression spring 2 relative to the fixed end, so as to prevent the compression spring 2 from shifting or twisting laterally during compression or extension. The slide rod 41 in the retainer 4 is arranged along the length direction of the compression spring 2, and the movable block 42 is slidably connected to the slide rod 41 through the slide hole 421. The movable end of the compression spring 2 is connected to the movable block 42, which is used to limit the compression or extension of the movable end relative to the fixed end along the length direction of the compression spring 2.

[0055] It should be noted that by setting the retainer 4, the movable end is limited to compressing or extending relative to the fixed end along the length direction of the compression spring 2, so that the compression spring 2 maintains a uniform force distribution in the deformed state, prevents local stress concentration, and improves the consistency and reliability of force transmission.

[0056] It should also be noted that the traction member 3 passes through the interior of the compression spring 2 and is connected to the movable end. By setting the retainer 4, the compression spring 2 is prevented from shifting laterally during compression or extension. Therefore, friction between the compression spring 2 and the traction member 3 can be avoided, which would affect the energy transfer efficiency. It also avoids wear caused by friction between the compression spring 2 and the traction member 3.

[0057] Meanwhile, since the slide bar 41 in the retainer 4 is arranged along the length direction of the compression spring 2, the stability of the compression spring 2 in the length direction is increased under the action of the slide bar 41, and the compression spring 2 is prevented from deforming in a non-perpendicular state; it also increases the structural strength of the energy storage assist component 100 and increases the service life of the energy storage assist component 100.

[0058] Furthermore, in this embodiment, a bushing is provided in the sliding hole 421. The bushing can be an oil-free bushing. The movable block 42 is slidably connected to the slide rod 41 through the bushing, thereby reducing the friction between the movable block 42 and the slide rod 41 and reducing energy loss caused by friction.

[0059] It should be noted that in this embodiment, the number of slide rods 41 is at least one. When there is only one slide rod 41, it can be located on the outer periphery or inside the compression spring 2. When there are multiple slide rods 41, depending on the size of the internal space and the reserved external space of the compression spring 2, the multiple slide rods 41 can be evenly located on the outer periphery of the compression spring 2, all of them can be evenly located inside the compression spring 2, or they can be located on both the outer periphery and inside the compression spring 2. The number of slide rods 41 and their positional relationship with the compression spring 2 do not constitute a limitation on this embodiment, provided that the function of the slide rods 41 is satisfied.

[0060] Furthermore, in this embodiment, as Figures 2 to 5 As shown, there are three slide rods 41, which are arranged in a circular array along the central axis of the compression spring 2. The triangular support structure formed by the three slide rods 41 can effectively limit the radial displacement of the movable block 42, suppress the lateral swaying of the compression spring 2 during spring compression, and further ensure that the deformation trajectory of the compression spring 2 moves along the length direction of the compression spring 2. At the same time, the three slide rods 41 arranged in a circular array can evenly distribute the axial load of the compression spring 2 to three support points, avoid local stress concentration, and thus extend the fatigue life of the slide rods 41 and the movable block 42.

[0061] Furthermore, in this embodiment, as Figure 2 and Figure 3 As shown, all three slide rods 41 are located inside the compression spring 2, and the three slide rods 41 form a channel through which the traction member 3 passes. The slide rods 41 being located inside the compression spring 2 not only does not affect the connection between the traction member 3 and the movable end of the compression spring 2, but also effectively limits the deformation trajectory of the compression spring 2 while reducing the volume of the energy storage assist assembly 100.

[0062] Furthermore, in this embodiment, as Figures 2 to 5 As shown, when there are multiple slide rods 41, in order to prevent the other end of the slide rod 41 from shifting or deforming, a fixing block 43 is set at the other end of the slide rod 41. Multiple slide rods 41 are connected to the fixing block 43 to maintain a stable distance between the slide rods 41, so that the movable block 42 can move more smoothly on the slide rod 41 and avoid the frictional force of the movable block 42 from increasing due to the deformation of the slide rod 41.

[0063] Furthermore, in this embodiment, the retainer 4 is used to limit the movement trajectory of the movable end of the compression spring 2 relative to the fixed end. Therefore, one end of the traction member 3 is connected to the movable end of the compression spring 2 through the movable block 42. The connection method can be a fixed connection or a detachable connection. For example, one end of the traction member 3 is connected to a bolt, and the movable block 42 is provided with a through hole. The bolt passes through the through hole and is connected to the movable block 42 by a nut. When one end of the traction member 3 is detachably connected to the movable block 42, the fixed block 43 is provided with a clearance through hole 431. The clearance through hole 431 is used to avoid the connection area between one end of the traction member 3 and the movable block 42, making it convenient to connect or disconnect one end of the traction member 3 through the clearance through hole 431.

[0064] It should be noted that, in this embodiment, to increase the reliability of the connection between the movable block 42 and the movable end of the compression spring 2, such as... Figure 4 and Figure 5 As shown, the movable block 42 has a protrusion 423 on the end face near the compression spring 2. The movable end is sleeved on the protrusion 423. The protrusion 423 facilitates the docking of the movable block 42 with the movable end of the compression spring 2, and avoids radial offset between the movable block 42 and the compression spring 2.

[0065] It should be noted that, in this embodiment, to increase the service life of the compression spring 2, the compression spring 2 can be mechanically sealed. This can be achieved in the following ways: Figures 1 to 3 As shown, the housing also includes a protective shell 12, which is sleeved on the outside of the compression spring 2 and connected to the base 11. By providing the protective shell 12, the compression spring 2 is mechanically protected, preventing external interference and thus increasing the service life of the compression spring 2; it also prevents the compression spring 2 from breaking and causing damage to the outside, thereby increasing safety.

[0066] Furthermore, in this embodiment, since a protective shell 12 is provided on the outside of the compression spring 2, during the deformation of the compression spring 2 caused by the traction member 3 driving the movable block 42, the movable block 42 moves within the protective shell 12. To avoid uneven gas distribution within the protective shell 12 and a pressure difference between the two ends of the movable block 42, which would increase the resistance to movement of the movable block 42, such as... Figure 4 As shown in the figure, at least one vent hole 422 can be provided on the movable block 42 to balance the air pressure at both ends of the movable block 42.

[0067] like Figure 6As shown, a second aspect of the embodiment discloses a photovoltaic tracking device, including a support member 200, a rotating shaft 300, and a photovoltaic module 400. The rotating shaft 300 includes a central shaft and a movable outer cylinder 301. The central shaft is connected to the support member 200, and the movable outer cylinder 301 is sleeved on the central shaft. The movable outer cylinder 301 can rotate around the axis of the central shaft. One end of the photovoltaic module 400 is connected to the movable outer cylinder 301, and a transmission wheel is connected to the movable outer cylinder 301.

[0068] It also includes the energy storage and assist component 100 as described above, with the base 11 connected to the support member 200, and the other end of the traction member 3 extending along the surface of the transmission wheel, with the extended end connected to the transmission wheel.
