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 industrial manufacturing, machine shops, and transportation, the movement of loads often exhibits periodic characteristics, such as the reciprocating motion of a robotic arm or the alternating effort-saving and effort-consuming movements of human joints. Typically, the energy saved during the effort-saving phase is converted into heat or dissipated through vibration, leading to energy waste. In recent years, with the development of green energy and efficient transmission technologies, energy recovery and reuse have become a research hotspot.

[0003] Currently, common energy recovery and reuse schemes mainly rely on the deformation of springs to recover energy. However, since the elastic coefficient of a spring is linearly related to its deformation, it is difficult to accurately match the nonlinear changes in energy loss during the effortless movement of the load. To solve these problems, an energy storage assist component is designed. When the energy storage assist component recovers load energy and uses it to assist the load in performing strenuous movements, the energy transfer delay during the spring deformation process will lead to insufficient energy recovery, thus affecting the assist efficiency. Therefore, the energy transfer delay during the spring deformation process is a technical 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 energy transfer delay during spring deformation 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 casing, including the base;

[0008] An elastic element includes a fixed end and a movable end, wherein the fixed end is connected to the base;

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

[0010] A transmission unit is connected to the base, and the transmission unit cooperates with the traction member to adjust the lever arm of the force exerted by the elastic member on the external load;

[0011] The pre-tightening structure includes an adjusting part and a connecting part. The adjusting part is located at the movable end, and the connecting part is located at one end of the traction member. One end of the traction member is connected to the movable end through the connecting part. The adjusting part is used to drive the movable end to move closer to or further away from one end of the traction member through the connecting part.

[0012] Optionally, the connecting part is a screw connected to one end of the traction member, and the adjusting part includes a movable block and an adjusting nut. The movable block is connected to the movable end, and the movable block is provided with a through hole for the screw to be inserted. The adjusting nut is located at one end of the movable block away from the traction member, and the adjusting nut cooperates with the screw.

[0013] Optionally, the screw is provided with a limiting notch, and the through hole cooperates with the screw to limit the screw from driving the traction member to rotate relative to the movable block.

[0014] Optionally, one end of the screw is provided with a connecting section, and the screw is connected to one end of the traction member through the connecting section.

[0015] Optionally, the nut is rotatably connected to the movable block.

[0016] Optionally, the housing further includes a first protective shell, which is fitted onto the elastic member and connected to the base.

[0017] Optionally, the first protective shell is a cylindrical component with one end closed and the other end open, and the open end of the cylindrical component is detachably connected to the base.

[0018] Optionally, the first protective shell includes a protective cylinder and a cover. The protective cylinder is a cylindrical component with openings at both ends. One end of the protective cylinder is connected to the base, and the other end is detachably connected to the cover.

[0019] Optionally, the elastic element is a helical spring.

[0020] Optionally, the elastic element is a compression spring. When the elastic element is a compression spring, one end of the compression spring near the transmission part is connected to the base, and the other end of the traction element passes through the interior of the compression spring and is connected to the movable end.

[0021] As a second aspect of this utility model, a photovoltaic tracking device includes the energy storage assist component described above.

[0022] The advantages of this invention are: it improves the working efficiency of the energy storage and assist component, facilitates the adjustment of the preload of the elastic element, and increases the safety of the energy storage and assist component.

[0023] First, in the energy storage assist component disclosed in this utility model, an adjustment part is provided at the movable end and a connecting part is provided at one end of the traction member. The adjustment part is used to adjust the distance between the movable end and one end of the traction member through the connecting part, thereby adjusting the deformation of the elastic member. This facilitates pre-tightening of the elastic member, so that the elastic member is in a deformed state when it does not receive traction force and begins to store energy immediately when it begins to be subjected to force. In other words, the elastic member has basic elastic potential energy at any position, avoiding energy transfer delay or energy loss, and improving the working efficiency of the energy storage assist component.

[0024] Secondly, when pre-tightening of the elastic component is required, simply rotating the adjusting nut allows adjustment of the component's deformation via the movable block. This adjustment method is simple and easy to operate. Furthermore, because a limiting notch is provided on the screw, and the through hole in the movable block mates with the screw, the screw will not rotate with the adjusting nut when adjusting the elastic component's deformation. Therefore, there is no need to specifically fix the screw, further simplifying the adjustment method and preventing the screw from causing the traction component to twist, thus affecting its service life.

[0025] Third, by setting a first protective shell in the energy storage assist component of this utility model, the first protective shell provides mechanical protection for the elastic component, isolates it from the external environment, and increases its service life; at the same time, the first protective shell can prevent the traction component or elastic component from popping out, thereby avoiding damage and impact on the outside world and increasing the safety of the energy storage assist component.

[0048] like Figures 1 to 4 As shown, this embodiment discloses an energy storage and booster component 100, comprising:

[0049] The housing 1 includes a base 11;

[0050] The elastic element 4 includes a fixed end and a movable end, wherein the fixed end is connected to the base 11;

[0051] The traction component 3 has one end connected to the movable end and the other end connected to an external load.

[0052] The transmission part 2 is connected to the base 11. The transmission part 2 cooperates with the traction member 3 and is used to adjust the lever arm of the force exerted by the elastic member 4 on the external load.

[0053] The pre-tightening structure 6 includes an adjustment part and a connecting part. The adjustment part is located at the movable end, and the connecting part is located at one end of the traction member 3. One end of the traction member 3 is connected to the movable end through the connecting part. The adjustment part is used to drive the movable end to move closer to or further away from one end of the traction member 3 through the connecting part.

[0054] It should be noted that in this embodiment, the base 11 is used to support the energy storage and assist component 100, the main shaft is rotatably connected to the base 11, and the fixed end of the elastic element 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 accordingly. The change in the shape of the base 11 does not constitute a limitation on this embodiment.

[0055] It should be noted that in this embodiment, the traction member 3 is used to connect the external load and the compression spring. If the external load is a simple linear motion, the external load and the compression spring 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, the rotational motion or other motion needs to be converted into linear motion through the transmission component 2, and then the compression spring is connected through the traction member 3. The lever arm of the force exerted by the elastic member 4 on the external load is adjusted through the cooperation between the traction member 3 and the transmission component 2. Therefore, the traction member 3 can adopt different structures or materials depending on the actual guiding component and transmission component 2. 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.

[0056] It should be noted that, in this embodiment, the pre-tightening structure 6 is implemented in ways including but not limited to the following:

[0057] The first implementation method is as follows: the connecting part is a chain, the chain is connected to the other end of the traction member 3, the adjusting part is hooked, and hooked to the other end of the elastic member 4. The chain is provided with multiple hooking points for the hook to be attached.

[0058] The second implementation method: such as Figures 2 to 4 As shown, the connecting part is a screw 63 connected to one end of the traction member 3. The adjusting part includes a movable block 61 and an adjusting nut 62. The movable block 61 is connected to the movable end, and the movable block 61 is provided with a through hole for the screw 63 to be inserted. The adjusting nut 62 is located at one end of the movable block 61 away from the traction member 3, and the adjusting nut 62 cooperates with the screw 63.

[0059] Furthermore, in this embodiment, when the connecting part is a screw 63 connected to one end of the traction member 3, in order to avoid directly driving the screw 63 and the traction member 3 to twist when adjusting the preload of the elastic member 4 by adjusting the adjusting nut 62, thus affecting the service life of the traction member 3, as follows: Figure 4 As shown, a limiting notch 631 is provided on the screw 63. The through hole cooperates with the screw 63 to limit the screw 63 from driving the traction member 3 to rotate relative to the movable block 61.

[0060] Furthermore, in this embodiment, to facilitate the connection between the screw 63 and one end of the traction member 3, such as... Figure 3 and Figure 4 As shown, a connecting section 632 is provided at one end of the screw 63, and a fixing part is provided on the connecting section 632. One end of the traction member 3 is connected to the connecting section 632 by a fixing bolt or fixing ring and other components. The connecting section 632 can also prevent over-adjustment. The screw 63 passes through the movable block 61 as a whole.

[0061] Furthermore, in this embodiment, the nut and the movable block 61 can be separately configured, or the nut can be rotatably connected to the movable block 61.

[0062] It should be noted that, in this embodiment, in order to increase the service life of the energy storage assist component 100, such as... Figures 1 to 3 As shown, the housing 1 also includes a first protective shell 12 and a second protective shell 13. The first protective shell 12 is sleeved on the elastic member 4 and connected to the base 11. The second protective shell 13 is covered on the base 11 and is used to seal the transmission part 2. The first protective shell 12 and the second protective shell 13 mechanically seal the elastic member 4 and the transmission part 2, isolate them from the external environment, and increase their service life. At the same time, the first protective shell 12 can also prevent the traction member 3 or the elastic member 4 from popping out, thereby avoiding damage to the outside world.

[0063] Furthermore, in this embodiment, to facilitate the adjustment of the preload force of the elastic element 4, the following settings can be made:

[0064] First, such as Figures 1 to 3 As shown, the first protective shell 12 is a cylindrical component with one end closed and the other end open, and the open end of the cylindrical component is detachably connected to the base 11. Specifically, a flange is provided at the open end of the cylindrical component, and the flange is fixed to the base 11 by bolts; or, the base 11 is provided with a fixing seat that mates with the open end of the cylindrical component, and the open end of the cylindrical component is inserted into the fixing seat.

[0065] Second, such as Figures 1 to 3 As shown, the first protective shell 12 includes a protective cylinder and a cover. The protective cylinder is a cylindrical component with openings at both ends. One end of the protective cylinder is connected to the base 11, and the other end is detachably connected to the cover. Specifically, the other end of the protective cylinder and the cover can be connected by a snap-fit ​​connection or by bolts.

[0066] It should be noted that when the energy storage assist component 100 of this embodiment is used, if it is necessary to pre-tighten the elastic member 4 or adjust the deformation state of the elastic member 4, it is only necessary to disassemble the cylindrical member or the cover, and the pre-tightening force of the elastic member 4 can be adjusted by adjusting the adjustment part.

[0067] It should be noted that, in this embodiment, the elastic element 4 stores energy through material deformation under external force, and releases the stored energy during the process of deformation recovery or reduction, and has the property of returning to the shape before the external force was applied. The elastic element 4 can be a tension spring, compression spring, coil spring, torsion spring, or rubber, or a combination of two or more of these. The selection of different materials or shapes of the elastic element 4 does not constitute a limitation on this embodiment, provided that the function of the elastic element 4 is satisfied.

[0068] Furthermore, in this embodiment, considering the spatial changes of the elastic element 4 during deformation, to save space, in this embodiment, as follows... Figure 2 and Figure 3 As shown, the elastic element 4 is a compression spring. When the elastic element 4 is a compression spring, one end of the compression spring near the transmission part 2 is connected to the base 11, and the other end of the traction element 3 passes through the interior of the compression spring and is connected to the movable end.

[0069] It should be noted that using a compression spring can improve space utilization. The fixed end of the compression spring can be directly connected to the base 11, eliminating the need for additional extension points on the base 11. This reduces the volume of the base 11, lowers material costs, and reduces processing difficulty.

[0070] like Figure 5 As shown, the second aspect of this 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 7 is connected to the movable outer cylinder 301.

[0071] 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 7, with the extended end connected to the transmission wheel 7.

[0072] The advantages of this embodiment are: it increases the assist effect of the energy storage assist component 100 and increases the stability and safety of the energy storage assist component 100.

[0073] First, in the energy storage assist component 100 disclosed in this embodiment, an adjustment part is provided at the movable end and a connecting part is provided at one end of the traction member 3. The adjustment part is used to adjust the distance between the movable end and one end of the traction member 3 through the connecting part, thereby adjusting the deformation of the elastic member 4, which facilitates the pre-tightening treatment of the elastic member 4, so that the elastic member 4 is in a deformed state when it does not receive traction force, and begins to store energy immediately when it begins to be subjected to force. That is, the elastic member 4 has basic elastic potential energy at any position, avoiding energy transfer delay or energy loss, and increasing the working efficiency of the energy storage assist component 100.

[0074] Secondly, when pre-tightening of the elastic element 4 is required, only the adjusting nut 62 needs to be rotated to adjust the deformation of the elastic element 4 via the movable block 61. The adjustment method is simple and easy to operate. Simultaneously, since a limiting notch 631 is provided on the screw 63, and the through hole in the movable block 61 cooperates with the screw 63, when adjusting the deformation of the elastic element 4 via the adjusting nut 62, the screw 63 will not rotate with the adjusting nut 62 due to the action of the limiting notch 631. Therefore, there is no need to specifically fix the screw 63, further simplifying the adjustment method and preventing the screw 63 from causing the traction element 3 to twist, thus affecting the service life of the traction element 3.

[0075] Third, by providing a first protective shell 12 in the energy storage assist component 100 of this embodiment, the first protective shell 12 provides mechanical protection for the elastic element 4, isolates it from the external environment, and increases its service life; at the same time, the first protective shell 12 can prevent the traction element 3 and the elastic element 4 from being ejected, thereby avoiding damage and impact on the outside world and increasing the safety of the energy storage assist component 100.
