[0002] This application claims priority to Chinese patent application No. 2023116219643, filed on November 30, 2023, entitled “Lock, Photovoltaic Bracket and Photovoltaic System,” the entire text of which is incorporated herein by reference. Technical Field

[0003] The present application relates to the field of photovoltaic technology, and in particular to a lock, a photovoltaic bracket and a photovoltaic system. Background Art

[0004] Solar photovoltaic power generation is a technology that uses an array of solar photovoltaic modules to receive incoming sunlight, convert the light energy into electrical energy through photovoltaic conversion, and then collect the generated electricity for use. Solar photovoltaic systems typically use photovoltaic brackets to mount the modules. A drive unit rotates the modules, ensuring that sunlight always reaches the modules directly, thereby improving solar energy absorption and utilization efficiency.

[0005] Photovoltaic racks generally have either single-point or multi-point drives. Single-point drive involves a single drive unit driving the main shaft. Multi-point drive involves multiple drive units driving the main shaft. For example, in extreme weather conditions such as strong winds, the axial torque exerted by the wind load on the main shaft gradually accumulates along the main shaft to the drive unit, affecting the reliability of the drive unit and, in turn, the photovoltaic power generation rate. Furthermore, the related technology cannot achieve high torque transmission.

DETAILED DESCRIPTION

[0050] The following will clearly and completely describe the technical solutions of this application in conjunction with the embodiments. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0051] To facilitate understanding of this embodiment, this embodiment is described in detail below with reference to the accompanying drawings.

[0052] Referring to Figures 1 to 3 , a lock 100 provided in one embodiment of the present application is applied to the main shaft of the photovoltaic bracket 10 shown in Figure 8 . The lock 100 includes a housing 110, an input member 120 at least partially located within a receiving groove 111 of the housing 110, and an output member 130 at least partially located within the receiving groove 111 of the housing 110. The input member 120 is configured with at least one input toggle portion 121; the output member 130 is configured with at least two output toggle portions 131, with the input toggle portion 121 located between the two output toggle portions 131. In other words, the output toggle portions 131 and the input toggle portions 121 are arranged alternately along the circumference. A pusher 141 and an elastic member 142 are disposed between each output toggle portion 131 and the adjacent input toggle portion 121. The elastic member 142 is connected between the pusher 141 and the output toggle portion 131. The elastic member 142 is used to drive the pusher 141 into a locked position. When the push member 141 is in the locked position, the box body 110 and the output member 130 cooperate to limit the push member 141 from approaching the input toggle portion 121 along the circumferential direction and abutting against the input toggle portion 121. It can be understood that the movement of the push member 141 approaching the output toggle portion 131 along the circumferential direction is not restricted.

[0053] The radial dimension of the input toggle portion 121 is smaller than the radial dimension of the pusher 141. That is, when the pusher 141 is in the locked position, the pusher 141's two radial ends respectively abut the housing 110 and the output member 130, allowing the housing 110 and the output member 130 to cooperate in restricting the pusher 141 from circumferentially approaching the input toggle portion 121. One radial end of the input toggle portion 121 abuts the housing 110, while the other radial end does not abut the output member 130. Therefore, the circumferential movement of the input toggle portion 121 is not restricted by the housing 110 or the output member 130. The input member 120 is configured to be operatively rotated to drive the pusher 141 away from the locked position via the input toggle portion 121, allowing the pusher 141 to abut the output toggle portion 131 and drive the output member 130 to rotate. As shown in FIG. 3 , the circumferential direction is indicated by arrow X.

[0054] As shown in Figures 1 to 3 and 8, when the lock 100 is applied to a photovoltaic support 10, the input member 120 can be connected to the first main shaft 210 of the photovoltaic support 10 by fasteners such as screws, and the output member 130 is connected to the second main shaft 220 of the photovoltaic support 10. This eliminates the need for a bearing assembly or the like between the first main shaft 210 and the second main shaft 220 to achieve power transmission. When the photovoltaic support 10 is operating normally, the rotational power of the drive unit 300 is transmitted to the input member 120 through the first main shaft 210, causing the input member 120 to rotate until the input toggle portion 121 abuts the pusher 141, thereby driving the pusher 141 away from the locked position. When the pusher 141 compresses the elastic member 142 and moves it from the locked position to abut against the output toggle 131, it drives the output toggle 131 to rotate, thereby transmitting the rotational power to the output member 130 and the second main shaft 220 connected to the output member 130, achieving synchronous rotation of the first main shaft 210 and the second main shaft 220, thereby ensuring the consistency of the orientation of the multiple photovoltaic modules (not shown) installed on the first main shaft 210 and the second main shaft 220, thereby ensuring the efficiency of photovoltaic power generation. By providing the output toggle 131 on both sides of the circumference of the input toggle 121, whether the input member 120 rotates clockwise or counterclockwise, the rotational power can be transmitted to the output member 130 through the output toggle 131 on the corresponding side, achieving torque transmission. At the same time, during the power transmission process, since the input toggle 121 is in rigid contact with the output toggle 131 through the pusher 141, it can achieve high torque transmission, which meets actual usage requirements.

[0055] When a wind load acts on the second main shaft 220, the second main shaft 220 will be torsionally deformed, and the output member 130 will rotate until the output toggle portion 131 compresses the elastic member 142 and abuts against the push member 141. Since the push member 141 in the locker 100 is in the locked position and there is a first gap between the push member 141 and the input toggle portion 121, the push member 141 cannot move in a direction close to the input toggle portion 121 until it abuts against the input toggle portion 121, that is, it cannot drive the input toggle portion 121 to rotate, so that the output member 130 cannot drive the input member 120 to rotate, so that the torque of the second main shaft 220 connected to the output member 130 cannot be transmitted to the first main shaft 210 connected to the input member 120. The torque is blocked at the locker 100, thereby reducing the risk of the torque being transmitted through the first main shaft 210 to the drive unit 300 and affecting its reliability, thereby improving the torsional resistance of the photovoltaic bracket 10 and ensuring the photovoltaic power generation rate. In the absence of external driving force, the pushing member 141 may be in the locked position, that is, when the wind load acts on the output member 130, the output toggle portion 131 cannot drive the pushing member 141 to continue moving. Of course, in the absence of external driving force, the pushing member 141 may also be between the locked position and the unlocked position (the position where the pushing member 141 moves to abut against the output toggle portion 131 is defined as the unlocked position). In this way, when the wind load acts on the output member 130, the output toggle portion 131 will drive the pushing member 141 to move slightly, causing it to move from the current position to the locked position, thereby achieving torque isolation.

[0056] As shown in FIG2 , in one embodiment, the input member 120 and the output member 130 may be an input shaft and an output shaft respectively, the input shifting portion 121 and the output shifting portion 131 may both be shifting claws, the pushing member 141 may be a roller, and the elastic member 142 may be a spring.

[0057] Referring to Figures 1 to 3 , in one embodiment, the input toggle portion 121 includes multiple input toggle portions 121 and multiple output toggle portions 131, which are alternately arranged along the circumference. By providing multiple input toggle portions 121 and output toggle portions 131, the rigid contact area between the input member 120 and the output member 130 is increased, thereby making the torque transmission between the input member 120 and the output member 130 more stable and reliable. For example, in the embodiment shown in Figure 3 , there are four input toggle portions 121 and four output toggle portions 131. There are two elastic members 142 between two adjacent input toggle portions 121; these two elastic members 142 are spaced apart at opposite ends of the output toggle portion 131 along the circumference. Compared with setting an elastic member 142 between the two input toggle parts 121, by setting two elastic members 142, each elastic member 142 can independently control a pushing member 141, thereby preventing the position of the pushing member 141 from being affected when transmitting torque in the forward direction or the reverse direction, resulting in a decrease in locking accuracy, thereby ensuring the reliability of the use of the locker 100.

[0058] Referring to Figures 2 to 4 , in one embodiment, the output toggle portion 131 is provided with limiting grooves 1311 at both ends along the circumference. When the pusher 141 is in the locked position, the elastic member 142 is partially located within the limiting grooves 1311. When the pusher 141 abuts the output toggle portion 131, the elastic member 142 is completely located within the limiting grooves 1311. In other words, the limiting grooves 1311 do not extend along the circumference of the output toggle portion 131. Furthermore, when the elastic member 142 is completely located within the limiting grooves 1311, the elastic member 142 has not reached its maximum compression, thereby not affecting its reliability. The provision of the limiting grooves 1311 not only secures the elastic member 142 in place but also regulates the compression path of the elastic member 142, preventing the elastic member 142 from shifting or bending during the movement of the pusher 141 until it abuts the output toggle portion 131, thereby affecting the subsequent locking accuracy.

[0059] Referring to Figures 2 to 4 , in one embodiment, when the pusher 141 is in the locked position, a first gap is defined between the pusher 141 and the adjacent input toggle portion 121. This arrangement prevents the pusher 141 from transmitting power to the input toggle portion 121 when in the locked position, preventing the output member 130 from rotating the input member 120. Torque is blocked at the lock 100, thereby reducing the risk of torque being transmitted through the first spindle 210 to the drive unit 300 and affecting its reliability. This improves the torsional resistance of the photovoltaic bracket 10 and ensures the photovoltaic power generation rate.

[0060] Referring to Figures 3 and 4 , in one embodiment, the radial spacing between the output member 130 and the housing 110 gradually increases along the circumferential direction between the input toggle portion 121 and the adjacent output toggle portion 131, and in the direction from the input toggle portion 121 toward the output toggle portion 131. Furthermore, when the pusher 141 is in the locked position, the radial spacing between the main body of the output member 130 and the housing 110 is equal to the diameter of the pusher 141. In other words, the outer surface of the output member 130 forms a profiled transitional arc. This variable diameter arrangement allows the pusher 141 to move toward the output toggle portion 131, allowing power to be transmitted from the input member 120 to the output member 130. However, the housing 110 and the output member 130 cooperate to restrict the pusher 141 from moving toward a smaller gap in the locked position, preventing it from moving toward the input toggle portion 121. This prevents power from the output member 130 from being transmitted to the input member 120, thus achieving torque isolation.

[0061] As shown in Figures 2 and 5 , in one embodiment, the lock 100 further includes a first bearing 151. Along the axial direction of the first bearing 151, the input member 120 and the output member 130 are respectively connected to either side of the first bearing 151. By providing the first bearing 151 between the input member 120 and the output member 130, direct contact between the input member 120 and the output member 130 during torque transmission, which would otherwise cause excessive wear, thereby improving the service life of the lock 100. In some embodiments, as shown in Figures 5 and 7 , the first bearing 151 can be a thrust roller bearing 1511, whose multiple cylindrical rollers are designed to abut against the input member 120 and the output member 120.

[0062] As shown in Figures 2 and 5, in one embodiment, a second bearing 152 is connected between the inner wall of the housing 110 and the input member 120. Since the input member 120 rotates relative to the housing 110 during normal operation of the photovoltaic bracket 10, the provision of the second bearing 152 between the input member 120 and the inner wall of the housing 110 prevents direct contact between the input member 120 and the housing 110, which can lead to wear and tear, thereby extending the service life of the lock 100. Furthermore, a third bearing 153 is connected between the inner wall of the housing 110 and the output member 130. The provision of the second bearing 152 and the third bearing 153 not only improves the torsional resistance of the main shaft, ensuring coaxial rotation and coaxiality between the input member 120 and the output member 130, enabling the lock 100 to withstand greater bending moments, but also reduces friction and wear between the input member 120, the output member 130, and the housing 110, thereby extending the service life of the lock 100. The second bearing 152 and the third bearing 153 may both be deep groove ball bearings.

[0063] As shown in Figures 2 and 5 , in one embodiment, the input member 120 is configured with a first stepped groove 122, in which the second bearing 152 is located; the output member 130 is configured with a second stepped groove 132, in which the third bearing 153 is located. Providing stepped grooves on both the input member 120 and the output member 130 not only facilitates assembly of the bearings but also reduces the radial space occupied by the input member 120 and the second bearing 152, making the locker 100 more compact.

[0064] As shown in Figures 2 and 5 , in one embodiment, the lock 100 further includes a first stopper 161 connected to the housing 110. The first stopper 161 abuts one side of the input member 120 along its own axial direction, thereby limiting the axial movement of the input member 120. By limiting the axial movement of the input member 120, the possibility of the input member 120 misaligning and causing the input toggle portion 121 to fail to abut the pusher 141 is reduced, thereby ensuring reliable torque transmission.

[0065] As shown in Figures 2 and 5, in some embodiments, the first position-limiting member 161 includes a first retaining ring 1611 connected to the inner wall of the housing 110. The first retaining ring 1611 abuts against one side of the input member 120 along its own axial direction and abuts against one side of the second bearing 152. Furthermore, the inner wall of the housing 110 is further provided with a first retaining groove 112 for retaining the first retaining ring 1611 to retain the first retaining ring 1611. In other embodiments, the first position-limiting member includes a first baffle connected to one side of the housing along its own axial direction. The first baffle abuts against one side of the input member along its own axial direction. The first baffle and the housing may be connected by fasteners such as screws.

[0066] As shown in Figures 2 and 5 , in some embodiments, the lock 100 further includes a second stopper 162 connected to the housing 110. The second stopper 162 abuts the output member 130 to limit axial movement of the output member 130. By limiting axial movement of the output member 130, the possibility of the output member 130 misaligning and causing the pusher 141 to fail to abut the output toggle portion 131 is reduced, thereby ensuring reliable transmission of input torque to the output member 130.

[0067] In some embodiments, as shown in Figures 2 and 5, the second position-limiting member 162 includes a second retaining ring 1621 connected to the inner wall of the housing 110. The second retaining ring 1621 abuts against one side of the output member 130 along its own axial direction and abuts against one side of the second bearing 152. Furthermore, the inner wall of the housing 110 is provided with a second retaining groove 113 for the second position-limiting member 162 to engage, thereby limiting the position of the second retaining ring 1621. In other embodiments, the second position-limiting member includes a second baffle connected to one side of the housing along its own axial direction. The second baffle abuts against one side of the output member along its own axial direction. The second baffle and the housing can be connected by fasteners such as screws.

[0068] Furthermore, as shown in FIG8 , one embodiment of the present application further provides a photovoltaic support 10, comprising a first main shaft 210, a second main shaft 220, and the aforementioned lock 100 connected between the first main shaft 210 and the second main shaft 220. The first main shaft 210 and the second main shaft 220 are used to connect a photovoltaic module. It is understood that the photovoltaic support 10 also includes a drive unit 300, and the first main shaft 210 is connected to the output end of the drive unit 300.

[0069] When the photovoltaic bracket 10 is operating normally, the rotational power of the drive unit 300 will be transmitted to the second main shaft 220 through the first main shaft 210 and the lock 100, achieving synchronous rotation of the first main shaft 210 and the second main shaft 220, thereby ensuring the consistency of the orientation of the multiple photovoltaic modules installed on the first main shaft 210 and the second main shaft 220, and ensuring the efficiency of photovoltaic power generation. When the wind load acts on the second main shaft 220, the torque is blocked at the lock 100, thereby reducing the risk of the torque being transmitted through the first main shaft 210 to the drive unit 300 and affecting its reliability, improving the torsion resistance of the photovoltaic bracket 10, and thus ensuring the photovoltaic power generation rate. Through the cooperation of the lock 100 and the drive unit 300, the torque holding point of the photovoltaic bracket is increased from one to multiple, which significantly improves the wind resistance of the entire photovoltaic bracket.

[0070] Furthermore, the present application also provides a photovoltaic system (not shown), comprising the photovoltaic bracket 10 and a photovoltaic module connected to the photovoltaic bracket 10. Since the photovoltaic system includes the photovoltaic bracket, it can not only realize power transmission, but also improve the torsional resistance of the photovoltaic bracket, thereby improving the reliability of the photovoltaic system.
