At this time, the first component and the second component cannot rotate relative to each other, and can achieve synchronous movement.

[0053] The present application is further described in detail below in conjunction with specific drawings.

[0054] As a first aspect of this embodiment, a clutch 1 is provided, such as Figures 1 to 7 As shown, it includes a first component 11 and a second component 12, the first component 11 includes a first body 111 and a ring sleeve 112, the first body 111 is provided with a first abutting portion 1111 and a first mounting portion 113, the ring sleeve 112 is fixedly connected to the first body 111, and the ring sleeve 112 includes a ring body 1121 and a ratchet portion 1122; the second component 12 includes a second body 121 and a ratchet arm 122, the second body 121 is annular and is provided with a second abutting portion 1211 that can abut against the first abutting portion 1111, and the ring sleeve 112 is coaxial with the second body 121 It is arranged that the first component 11 and the second component 12 can rotate relative to each other through the cooperation between the ring sleeve 112 and the second main body 121; the second main body 121 is also provided with a second mounting portion 127, and the first mounting portion 113 and the second mounting portion 127 are both used to connect with different external loads; the pawl arm 122 is used to cooperate with the ratchet portion 1122, and the pawl arm 122 is hinged to the second main body 121; when the pawl arm 122 is engaged with the ratchet portion 1122, the first abutting portion 1111 and the second abutting portion 1211 abut against each other, and the first component 11 and the second component 12 move synchronously.

[0055] Regarding the connection relationship between the first component 11 and the second component 12: Figure 1 and Figure 2 As shown, in some embodiments, the ratchet portion 1122 is disposed on the outer circumference of the ring sleeve 112, and the ring sleeve 112 is sleeved by the second body 121. In this case, the ratchet arm 122 is usually disposed outside the ring sleeve 112. In this way, since the connection part is disposed outside, it is convenient to install, disassemble and repair. In other embodiments, the second body 121 is sleeved in the ring sleeve 112, and the second body 121 is sleeved by the ring sleeve 112. In this case, the ratchet arm 122 is usually disposed inside the ring sleeve 112, and the same technical effect can also be achieved.

[0056] The first abutting portion 1111 and the second abutting portion 1211: Figure 3 In the embodiment shown in FIG. 1 , the first abutting portion 1111 extends along the tangent direction of the first body 111, and the second abutting portion 1211 extends along the tangent direction of the second body 121. Figure 4In the illustrated embodiment, center lines of the first abutting portion 1111 , the second abutting portion 1211 , the first mounting portion 113 , and the fourth mounting portion are located in the same plane.

[0057] In addition, by providing the first abutting portion 1111 and the second abutting portion 1211, the ratchet portion 1122 only needs a ratchet in one direction to achieve the synchronous movement of the first component 11 and the second component 12, which can reduce the processing steps and reduce the cost. Figure 7 In the illustrated embodiment, only a single ratchet is required to complete the work, which can further reduce the cost of processing and materials.

[0058] Regarding the synchronous movement of the first component 11 and the second component 12: it can be understood that the engagement of the pawl arm 122 with the ratchet portion 1122 limits the first component 11 and the second component 12 from rotating in the first direction, while the abutment between the first abutment portion 1111 and the second abutment portion 1211 limits the first component 11 and the second component 12 from rotating in the opposite direction of the first direction. At this time, the first component 11 and the second component 12 cannot rotate relative to each other and can only move synchronously.

[0059] In some embodiments, the ring body 1121 and the ratchet portion 1122 are separately provided, and the ratchet portion 1122 is connected to the ring sleeve 112 in an embedded manner. Figure 2 and Figure 7 As shown, the ratchet portion 1122 includes a ratchet and a first engaging position, and the ring sleeve 112 is provided with a second engaging position matched with the engaging position. After the first engaging position and the second engaging position are connected, the ratchet portion 1122 cannot be separated from the ring body 1121 along the radial direction of the ring body 1121. It should be noted that in the above embodiment, the ratchet portion 1122 is only provided with one tooth meshing with the pawl arm 122, while in other embodiments, the ratchet portion 1122 may be provided with a plurality of teeth.

[0060] Regarding the materials of the ratchet portion 1122 and the ring body 1121: the material strength of the ratchet portion 1122 is greater than the material strength of the ring body 1121. This is because after the ratchet portion 1122 contacts the ratchet arm 122, the main force-bearing part on the ring sleeve 112 is the ratchet portion 1122 that cooperates with the ratchet arm 122. Therefore, it is necessary to pay special attention to the material strength of the ratchet portion 1122. However, if the entire ring sleeve 112 is made of a high-strength material, the processing of high-strength materials is more complicated, which will undoubtedly increase too much unnecessary cost. In some embodiments, the material of the ratchet portion 1122 is steel, and the material of the ring body 1121 is aluminum. The ring body 1121 is processed by die-casting. After the ring body 1121 is processed, the steel ratchet portion 1122 is embedded in the ring body 1121, so that the ratchet portion 1122 cannot be separated from the ring body 1121 along the radial direction of the ring body 1121. This arrangement can simplify the processing steps of the ring body 1121. Since the processing of the ratchet portion 1122 is relatively simple, the combination of the ring body 1121 and the ratchet portion 1122 can improve the production and processing efficiency while ensuring the strength of the parts.

[0061] In other embodiments, the ring body 1121 and the ratchet portion 1122 are integrally provided, and the integrally provided ring sleeve 112 can be directly used for assembly with external components after processing, thereby effectively simplifying the assembly steps required for the separate arrangement of the ring body 1121 and the ratchet portion 1122, and significantly reducing the production cost of this link. In addition, the integrally designed ring sleeve 112 can also be processed by die-casting, which further improves production efficiency and enables it to be efficiently applied to mass production.

[0062] The first component 11 and the second component 12 also include a bearing for supporting relative rotation. The bearing is arranged on the first component 11 or the second component 12. The bearing can be a rolling bearing or a self-lubricating bearing 123. Figure 5 In the illustrated embodiment, the bearing is provided in the second component 12, and the bearing is a self-lubricating bearing 123. The self-lubricating bearing 123 has many advantages, including operation without lubricating oil, reduced maintenance and operation costs, improved cleanliness and environmental protection, etc. In addition, the self-lubricating bearing 123 has good wear resistance and self-lubricating properties, can operate stably under harsh environments, reduces the risk of failure due to insufficient lubrication, and extends the service life of the clutch 1.

[0063] The clutch 1 proposed in this embodiment further includes a first elastic member disposed in the second assembly 12, the first elastic member is used to provide elastic force for the pawl arm 122, one end of the first elastic member is connected to the second body 121, and the other end is connected to the pawl arm 122. Figure 7In the illustrated embodiment, the first elastic member is a torsion spring 124, which provides a counterclockwise rotating elastic force for the pawl arm 122. The elastic force drives the second ratchet on the pawl arm 122 to move toward the ring sleeve 112, allowing the pawl arm 122 to dock with the ring sleeve 112. At this time, the ring sleeve 112 rotates relative to the second component 12 until the ratchet portion 1122 engages with the pawl arm 122, and the first component 11 and the second component 12 cannot rotate relative to each other in one direction.

[0064] In some embodiments, a first sensor 125 is further included. The first sensor 125 is disposed on the second body 121 and is used to detect the rotation angle of the pawl arm 122. Figure 7 In some of the embodiments shown, the first sensor 125 is a position sensor, which is disposed at one end of the ratchet arm 122 away from its hinged portion. When the ratchet arm 122 rotates a certain angle and contacts the first sensor 125, the first sensor 125 is triggered. The position sensor also has the characteristics of high stability and low price. Through the above application, when it cooperates with the power assembly 13 described later in this embodiment, the power assembly 13 drives the ratchet arm 122 to rotate, and stops the operation of the power assembly 13 when it detects that the ratchet arm 122 rotates to engage with the ratchet portion 1122. In other embodiments, the first sensor 125 can be an angle sensor, which can accurately detect the rotation angle of the ratchet arm 122 and has the advantage of high precision.

[0065] The second sensor 126 is also included. The second sensor 126 is disposed on the second body 121 and is used to detect the rotation angle of the ring 112. Figure 7 In some of the embodiments shown, the second sensor 126 is arranged at the rotation position of the ring sleeve 112. The second sensor 126 is a position sensor, and a protrusion 1123 is provided on the circumferential surface of the ring sleeve 112. When the ring sleeve 112 rotates until the protrusion 1123 contacts the second sensor 126, the second sensor 126 is triggered, thereby detecting the relative rotation angle of the first component 11 and the second component 12, thereby once again improving the automation and intelligent monitoring level of the clutch 1.

[0066] By using the first sensor 125 and the second sensor 126, the clutch 1 can be accurately monitored and prevented from faults in real time, thus optimizing work efficiency, improving the level of automation, and reducing human operation errors. The sensor data can also be used for predictive maintenance, ensuring the safety of the clutch 1 during operation, and improving the overall performance and reliability of the clutch 1 system.

[0067] In such Figure 7 Some of the embodiments shown in the figure further include a power assembly 13 , which is used to drive the pawl arm 122 to engage with or disengage the ratchet portion 1122 .

[0068] In such Figure 7 In some embodiments shown, the power assembly 13 includes a motor 131, a first gear 132, a second gear 133, a screw 134 and a screw nut 135, wherein the first gear 132 is fixedly connected to the output end of the motor 131, the first gear 132 and the second gear 133 are meshed, the second gear 133 and the screw 134 are fixedly connected, the screw 134 and the screw nut 135 are threadedly connected, and the screw nut 135 can drive the ratchet arm 122 to move. The motor 131 drives the first gear 132 to rotate, the first gear 132 drives the second gear 133 to rotate, the second gear 133 drives the screw 134 to rotate, the screw 134 drives the screw nut 135 to move linearly along the screw 134, and the ratchet arm 122 is driven by the linear motion of the screw nut 135 to control the engagement or separation of the ratchet arm 122 and the ratchet portion 1122. Secondly, through automatic adjustment, the system can maintain the best working state and improve efficiency and performance; in addition, automatic control reduces the risk of operating errors and system failures, enhances safety and reliability; moreover, it also increases the functionality and applicability of the system, such as realizing functions such as automatic switching.

[0069] The output end of the power assembly 13 can be fixedly connected to the ratchet arm 122, and when the ratchet arm 122 needs to be engaged with the ratchet portion 1122, the ratchet arm 122 is controlled to move toward the ratchet portion 1122, and when the ratchet arm 122 needs to be separated from the ratchet portion 1122, the ratchet arm 122 is controlled to move away from the ratchet portion 1122. The output end of the power assembly 13 can also be movably connected to the ratchet arm 122, such as Figure 7 In the illustrated embodiment, the pawl arm 122 can move within a limited range of the lead screw nut 135. When the lead screw nut 135 moves in the second direction, it drives the pawl arm 122 to rotate in a direction away from the ratchet portion 1122. Usually, additional components are required to apply a force to the pawl arm 122 that moves in the opposite direction of the second direction, so as to achieve engagement and disengagement of the clutch 1.

[0070] Furthermore, the power assembly 13 may also include a third sensor, which can provide accurate and reliable clutch 1 operation by detecting the travel distance of the lead screw nut 135, simplify system operation and reduce human errors. In addition, regarding the detection object of the third sensor, the third sensor can also detect the rotation speed of the motor 131, the first gear 132, the second gear 133 or the lead screw 134, and can also achieve similar technical effects.

[0071] In some embodiments, a second elastic member is provided between the first abutting portion 1111 and the second abutting portion 1211 to provide elastic force for the first abutting portion 1111 and the second abutting portion 1211 to move away from each other, thereby preventing the problem of overall vibration caused by the gap in the clutch 1 component under conditions such as wind force. In addition, the provision of the second elastic member also buffers the abutment between the first component 11 and the second component 12, and when applied to the foldable photovoltaic device proposed in this embodiment, it can make it run more smoothly and reliably.

[0072] Regarding the connection method between the first body 111 and the ring sleeve 112: There are many ways to fix the first body 111 and the ring sleeve 112, which can be a detachable fixed connection such as threaded connection, clamping or key connection, or a non-detachable fixed connection such as one-piece molding, welding, riveting or crimping. Figure 2 In the embodiment shown, the ratchet portion 1122 is provided on the outer circumference of the annular sleeve 112, the inner circumference of the annular sleeve 112 is provided with a first spline that cooperates with the spline shaft 14, the first body 111 is annular and its inner circumference is provided with a second spline that cooperates with the spline shaft 14, and the clutch 1 further includes a spline shaft 14, and the first body 111 and the annular sleeve 112 are fixedly connected by the spline shaft 14. The above-mentioned spline connection method can make the transmission in the clutch 1 more stable, improve the bearing capacity, improve the reliability, and can also be easily disassembled for inspection and maintenance when necessary.

[0073] In other embodiments, the spline shaft 14 is integrated with the external component, and while achieving a fixed connection between the first body 111 and the ring sleeve 112 , it also serves the function of connecting with the external component. Such a configuration can further improve the integration of the clutch 1 .

[0074] As the first aspect of this embodiment, a photovoltaic device is proposed, including the clutch 1 proposed in this embodiment, and also including a drive shaft assembly 2 and a photovoltaic panel 3; the clutch 1 is fixedly connected to the output end of the drive shaft assembly 2 through the first assembly 11 or the second assembly 12; the first assembly 11 is connected to a photovoltaic panel 3, and the second assembly 12 is connected to a photovoltaic panel 3.

[0075] In such Figure 8 and Fig. 9In the embodiment shown, the photovoltaic device further includes a column 4, the fixed portion of the drive shaft assembly 2 is fixedly connected to the column 4, two sets of clutches 1 proposed in this embodiment are arranged at the two ends of the output end of the drive shaft assembly 2, and the first mounting portion 113 and the second mounting portion 127 are respectively fixedly connected to the two photovoltaic panels 3. When the photovoltaic device tracks sunlight, the pawl arm 122 and the ratchet portion 1122 are engaged and the first abutment portion 1111 and the second abutment portion are abutted, and the drive shaft assembly 2 drives the two photovoltaic panels 3 to rotate synchronously through the clutch 1. When the photovoltaic device needs to be folded and retracted, the pawl arm 122 and the ratchet portion 1122 are separated and the first abutment portion 1111 and the second abutment portion are also separated, and the drive shaft assembly 2 drives the first assembly 11 to rotate. At this time, the second assembly 12 cannot rotate synchronously with the first assembly 11, so the first assembly 11 rotates relative to the second assembly 12 until the two are folded together, so that the photovoltaic device reaches a folded state.
