[0034] 2、In the locked state of the locking structure, the unlocking member is immediately retracted after cooperating with the third abutting portion. At this time, the lock bolt needs to immediately leave the lock bolt groove to achieve unlocking, otherwise after the unlocking member is retracted, the locking member will be rotated in the second direction by the action of the second elastic member to make the first abutting portion and the second abutting portion restore abutting. However, when the locking structure is applied to a photovoltaic device or other device, considering the running time of the program or other functional needs, it is often difficult to immediately make the lock bolt separate from the lock bolt groove. Therefore, through the setting of the first clamping position in the limiting member and the second clamping position in the locking member, when the unlocking member reversely rotates the locking member in the second direction, the first clamping position cooperates with the second clamping position to make the locking member unable to continue rotating in the second direction. After the lock bolt separates from the lock bolt groove, the lock hook rotates in the first direction, and the lock hook pushes the limiting member to release the cooperation of the first clamping position and the second clamping position. At this time, the lock hook has already moved to the state of waiting for locking, and the locking member rotates in the second direction until it contacts the lock hook. The above structure is cleverly arranged to make the locking structure return to the state of waiting for locking after locking, so that the locking structure runs more smoothly and reliably.

[0035] 3、When the other end of the second elastic member is connected with the limiting main body, the second elastic member not only provides the locking member with elastic force for rotating in the second direction, but also provides the limiting main body with elastic force for rotating in the third direction in the reverse direction. The second elastic member has two functions, which saves the need of the limiting main body for another component (in some embodiments, the fourth elastic member), reduces the manufacturing cost, saves the space, and improves the overall efficiency of the system.

[0036] 4、The position sensor can instantly obtain the state of the solar device through detection of the locking assembly, so as to more facilitate the control of the unlocking member to switch between the unlocking state and the locking state, and improve the degree of automation.

[0037] 5、In some photovoltaic devices in which photovoltaic panels are arranged on both sides of the stand, the locks formed by the symmetrically arranged locking structures can be combined with the photovoltaic devices arranged on both sides of the stand. For example, the solar device proposed in the third aspect of the present embodiment has a folding storage function, and the photovoltaic panels on both sides can be fixed with the lock when the photovoltaic panels are folded, so that the photovoltaic panels on both sides are indirectly fixed with the stand, the solar device becomes a whole, and the structure is more compact and reasonable, which can keep stable in bad weather such as wind.

[0049] The utility model will be made further detailed explanation in combination with specific drawing.

[0050] As Figures 1 to 5As shown, as the first part of the specific embodiment, a locking structure is proposed, including a lock bolt, a lock body 11, a lock hook 12, a locking piece 13 and a limiting piece 14. The lock hook 12 is rotatably connected with the lock body 11, the lock hook 12 is provided with a locking groove for cooperating with the lock bolt, the lock hook 12 is provided with a first abutting portion 121, and the locking structure further includes a first elastic member, which applies a elastic force to the lock hook 12 in a first direction D1. The locking piece 13 is rotatably connected with the lock body 11, the locking piece 13 is provided with a locking arm 131, and the locking structure further includes a second elastic member, the locking arm 131 is provided with a second abutting portion 1311 cooperating with the first abutting portion 121, one end of the second elastic member is connected with the locking piece 13 to apply an elastic force to the locking piece 13 in a second direction D2, and the locking structure is in a locked state when the first abutting portion 121 abuts against the second abutting portion 1311. The limiting piece 14 is rotatably connected with the lock body 11, the limiting piece 14 is provided with a first clamping portion 1421, the locking piece 13 is provided with a second clamping portion 1312 cooperating with the first clamping portion 1421, and the limiting piece 14 has a movement tendency of moving the first clamping portion 1421 towards the second clamping portion 1312.

[0051] The locking structure is as shown in the figure Figure 2 The state, in use, the lock bolt drives the lock hook 12 to rotate in the opposite direction of the first direction D1, the lock hook 12 forces the locking piece 13 to rotate in the opposite direction of the second direction D2, until the first abutting portion 121 rotates to a position where it can cooperate with the second abutting portion 1311, the lock hook 12 and the locking piece 13 can relatively freely rotate, the locking piece 13 rotates in the first direction D1 under the action of the second elastic member, so that the second abutting portion 1311 cooperates with the first abutting portion 121, and the locking structure is in Figure 3 The locked state as shown.

[0052] Triggering unlocking, as Figure 4 shown, the locking piece 13 rotates in the opposite direction of the second direction D2 under the action of an external force, and when the second abutting portion 1311 is disengaged from the cooperation with the first abutting portion 121, the second clamping portion 1312 cooperates with the first clamping portion 1421.

[0053] The lock bolt is driven by an external force to disengage from the locking groove, the lock hook 12 rotates to the initial position in the first direction D1, and in the process of rotation, the lock hook 12 pushes the limiting piece 14 to separate the first clamping portion 1421 and the second clamping portion 1312, and the locking piece 13 rotates to the initial position in the second direction D2, that is Figure 2 The locked state.

[0054] In Figure 2In some embodiments as shown, the limiting member 14 comprises a limiting body 141 and a limiting arm 142, the limiting member 14 is hinged to the lock body 11 through the limiting body 141, the limiting arm 142 is hinged to the limiting body 141, and the first clamping portion 1421 is arranged on the limiting arm 142. A third elastic member is further arranged, which makes the limiting arm 142 have a tendency to rotate towards the third direction D3. The locking member 13 further comprises a first pushing portion 133, which can make the limiting body 141 rotate towards the third direction D3 when cooperating with the limiting body 141.

[0055] In other embodiments, the limiting member 14 is an integral body, and the limiting member 14 has sufficient rotating space in the lock body 11. The other end of the second elastic member is connected to the limiting member 14, and the second elastic member provides elastic force to the limiting member 14 to rotate towards the third direction D3. In the above-mentioned embodiments, the third elastic member is not needed, and only the cooperation of the second elastic member can achieve the movement tendency of the first clamping portion 1421 of the limiting member 14 towards the second clamping portion 1312.

[0056] In some embodiments, the other end of the second elastic member is connected to the limiting body 141, and the second elastic member provides elastic force to the limiting body 141 to rotate towards the opposite direction of the third direction D3. In other embodiments, the other end of the second elastic member is connected to the lock body 11, and the locking structure further comprises a fourth elastic member, which makes the limiting body 141 have a tendency to rotate towards the opposite direction of the third direction D3.

[0057] In some embodiments as shown, Figure 5 In the embodiments as shown, the limiting member 14 is further provided with a second pushing portion, which is the end of the limiting arm 142 of the limiting member 14, i.e. the part of the limiting arm 142 that contacts the lock hook 12, and the lock hook 12 is provided with a third pushing portion that cooperates with the second pushing portion. When the first clamping portion 1421 and the second clamping portion 1312 cooperate, the third pushing portion pushes the second pushing portion to make the limiting member 14 move away from the locking member 13 when the lock hook 12 rotates towards the first direction D1, until the first clamping portion 1421 and the second clamping portion 1312 are separated. Figure 5 As shown, the third pushing portion and the first abutting portion 121 are the same part, and multiple parts are not needed to achieve the two functions, so that the integration of the structure is higher, and the cost is reduced.

[0058] In some embodiments, the lock body 11 is provided with a lock bolt slot for accommodating the lock bolt, and the lock bolt slot and the locking slot are arranged in correspondence and overlap.

[0059] In some embodiments, at least one position sensor 18 is further included, which is used to detect the movement position of the lock hook 12 and / or the locking member 13. Figures 2 to 5In the illustrated embodiment, the position sensor 18 includes a permanent magnet 181 and a sensor circuit 182. The sensor circuit 182 has a preset position for detecting the position of the permanent magnet 181. The permanent magnet 181 is mounted on the lock hook 12 and the locking member 13. The sensor circuit 182 is mounted on the lock body 11. When the lock hook 12 or the locking member 13 rotates, the permanent magnet 181 rotates synchronously. When the permanent magnet 181 moves to the preset position of the sensor circuit 182, the sensor circuit 182 detects the position change and sends a feedback signal to the control circuit. The position sensor 18 can accurately detect the position changes of the lock hook 12 and the locking member 13 and adjust the overall state of the locking structure based on the detected data. The position sensor 18 can also be an infrared sensor or a resistance sensor, etc.

[0060] In some embodiments, a fifth elastic element 17 is also included. The fifth elastic element 17 is disposed on the bolt and / or lock body 11, and in the locked state, the bolt and lock body 11 abut against each other through the fifth elastic element 17. Figures 2 to 5 In the illustrated embodiment, the fifth elastic element 17 is disposed in the bolt groove. After the bolt enters the bolt groove, the fifth elastic element 17 can effectively buffer the impact force that may be generated when the bolt engages with the hook 12, reducing structural damage and improving structural stability. Furthermore, in some other embodiments, a sensor is also provided in the bolt groove. The sensor is used to detect whether the bolt is located in the locking groove, thereby determining whether the locking structure is in a locked or unlocked state.

[0061] As the second part of this specific embodiment, a lock 1 for a solar energy device is proposed, comprising two sets of the above-described locking structures, and the two sets of locking structures are symmetrically arranged. Figures 1 to 5 As shown, the lock 1 for the solar energy device also includes a mounting part 16 for fixed connection with the solar energy device.

[0062] In some embodiments, an unlocking member 15 is also included, which causes the locking member 13 to rotate in the second direction D2, thereby separating the first abutment portion 121 and the second abutment portion 1311 until the first locking position 1421 and the second locking position 1312 engage.

[0063] like Figures 2 to 5 As shown, in some embodiments, the unlocking member 15 includes a driving part 151 and a trigger part 152, and the locking member 13 also includes a third abutting part 132 that cooperates with the trigger part 152. The driving part 151 drives the trigger part 152 to abut against the third abutting part 132, thereby separating the first abutting part 121 and the second abutting part 1311.

[0064] The drive unit 151 provides a power source for the trigger unit 152 and can have various structures, such as a transmission structure composed of a motor, gears, and shafts. In some embodiments, the drive unit 151 includes a motor, a lead screw, and a lead screw nut. The output end of the motor is connected to the lead screw, and the lead screw nut is connected to the trigger unit 152. The rotation of the motor drives the trigger unit 152 to move linearly. In other embodiments, a hydraulic push rod or similar structure can be used to provide the power source, which will not be described in detail here.

[0065] It should be noted that the working cycle of the aforementioned unlocking component 15 is as follows: after the driving part 151 pushes the trigger part 152 to move towards the third abutment part 132, it immediately springs back and retracts the trigger part 152, so as to push the trigger part 152 from... Figure 3 Exercise to Figure 4 and Figure 5 Reply to Figure 3 One cycle is defined as follows: When the unlocking component 15 receives an unlocking signal, it operates for one cycle, and this part of the unlocking component 15 returns to its original state. Figure 3 The ground is in a collapsed state.

[0066] In such Figure 2 In some embodiments shown, a trigger 152 can simultaneously push two symmetrically arranged locking structures to achieve synchronized unlocking actions. The trigger 152 abuts against the third abutment 132 in the two locking structures via a fourth abutment. The fourth abutment can be adjusted according to the structural changes of the locking member 13 in different locking structures. Figure 2 In this embodiment, the fourth abutment is composed of two inclined surfaces that abut against different third abutment portions 132 respectively. In this case, the movement of the third abutment portion 132 is smoother when the fourth abutment portion pushes the third abutment portion 132.

[0067] The locking structure has a locked state, a locked state, and an unlocked state. The various states are described in detail below with reference to the accompanying drawings:

[0068] Figure 2 The locking structure is in the locked state, at which point the locking hook 12 rotates until the opening of the locking groove faces the position where the bolt is to be engaged. Figure 3 In the locked state of the locking structure, the locking hook 12 is driven by the bolt to rotate in the opposite direction of the first direction D1 until the first abutting part 121 abuts against the second abutting part 1311. Figure 5In the unlocked state of the locking structure, the unlocking member 15 abuts against the third abutment part 132, causing the locking member 13 to rotate in the opposite direction of the second direction D2 until the first abutment part 121 separates from the second abutment part 1311. The first locking position 1421 engages with the second locking position 1312, and the locking hook 12 is acted upon by the bolt and / or the first elastic member, causing the locking hook 12 to rotate in the first direction D1. The third pushing part on the locking hook 12 pushes the second pushing part on the limiting member 14, causing the limiting member 14 to rotate in the opposite direction of the third direction D3, causing the first locking position 1421 to separate from the second locking position 1312. The locking member 13 rotates in the second direction D2, and the locking structure returns to its unlocked state. Figure 1 The state shown is the lock-in state.

[0069] As the third part of this specific embodiment, a solar energy device is proposed, including the lock 1 for the solar energy device described above, and also including a column 2, a tracking bracket 3 and a light-receiving component. The locking structure is fixedly connected to the column 2, the fixed end of the tracking bracket 3 is fixedly connected to the column 2, and the moving end of the tracking bracket 3 is fixedly connected to the light-receiving component.

[0070] The solar energy device also includes a lock 1 for photovoltaic solar energy devices as described in this specific embodiment. When the lock 1 is installed on the column 2, the locking bolt can be installed on either the light-receiving component or the tracking bracket 3, achieving similar technical effects. It should be noted that the installation positions of the lock 1 and the locking bolt are interchangeable; that is, the locking bolt can be installed on the column 2, and the lock 1 can be installed on either the light-receiving component or the tracking bracket 3.

[0071] like Figure 5 and Figure 6 As shown, the single-sided "T"-shaped cantilever dual-axis tracking bracket 3 includes an X-axis 31 and a Y-axis 32 arranged perpendicularly to each other. The X-axis 31 and Y-axis 32 each include a rotating part and a fixed part that can rotate around their own axes. The fixed part of the X-axis 31 is fixedly connected to the column 2, the rotating part of the X-axis 31 is fixedly connected to the fixed part of the Y-axis 32, and the rotating part of the Y-axis 32 is fixedly connected to the photovoltaic panel 4. The photovoltaic panel 4 is equipped with a locking bolt. After the locking bolt engages with the lock 1, the photovoltaic panel 4 is fixedly connected to the column 2, ensuring the overall stability of the solar energy device. Under suitable tracking conditions, the unlocking component 15 is controlled to release the lock 1, allowing the solar energy device to control the X-axis 31 and Y-axis 32 to drive the photovoltaic panel 4 for solar tracking.

[0072] In some embodiments, the extending direction of the mounting portion 16 is perpendicular to the extending direction of the bolt groove opening. For example... Figures 2 to 6 As shown, when the lock 1 for the solar energy device is installed on the photovoltaic panels 4 on both sides of the column 2, the two photovoltaic panels 4 can be rotated to both sides of the column 2 and can respectively cooperate with the paired locking structure to put the solar energy device into a locked state, thereby improving its stability.

[0073] In some embodiments, the mounting portion 16 is a ring-shaped pressing plate. As shown in Figure 1 , Figure 5 and Figure 6 , it can be easily sleeved on the stand pole and fixedly connected thereto by bolts and nuts. In other embodiments, it can also be fixedly connected by welding or the like.

[0074] In some embodiments, the limiting member 14 is rotatably connected with the lock body 11. In this case, the limiting member 14 can be rotatably connected with the lock body 11 as a whole, or can be divided into two parts as shown in the embodiment of Figures 2 to 5 . In the embodiment in which the limiting member 14 is divided into two parts, the limiting member 14 includes a limiting main body 141 and a limiting arm 142, the first clamping portion 1421 is arranged on the limiting arm 142, the limiting arm 142 is hingedly connected with the limiting main body 141, and the limiting main body 141 is rotatably connected with the lock body 11, so that the limiting member 14 is rotatably connected with the lock body 11 through the limiting main body 141.

[0075] It should be noted that the manner or structure of rotatably connecting the lock hook 12, the locking member 13, and the limiting member 14 (the limiting main body 141) with the lock body 11 can be hinged connection, shaft hole connection, or flexible connection, which can be understood by those skilled in the art, and therefore will not be described in detail here.

[0076] Regarding the first direction D1, the second direction D2, and the third direction D3, they are shown in the embodiment of Figures 2 to 5 , but it should be noted that the directions can be changed according to the changes of the structure by those skilled in the art, and therefore will not be described in detail here.

[0077] Regarding the first elastic member, the second elastic member, the third elastic member, and the fourth elastic member, in the embodiment of the locking structure shown in Figures 1 to 5 , the first elastic member, the second elastic member, and the third elastic member are all torsion springs in order to avoid too much confusion in the drawing, and the torsion springs have the advantages of small size and low cost. In other embodiments, according to actual needs, components with elasticity such as tension springs, coil springs, or rubbers can be selected and used, and therefore will not be described in detail here.

In use, the bolt drives the locking hook to rotate in the opposite direction to the first direction, and the locking hook forces the locking member to rotate in the opposite direction to the second direction until the first abutment part rotates to a position that can cooperate with the second abutment part. The locking hook and the locking member can rotate freely relative to each other. Under the action of the second elastic member, the locking member rotates in the second direction, so that the second abutment part cooperates with the first abutment part, and the locking structure is in a locked state. When unlocking is triggered, the locking member rotates in the opposite direction to the second direction under the action of external force. When the second abutting part disengages from the first abutting part, the second locking position engages with the first locking position, and the locking structure is in a pre-unlocked state. The bolt disengages from the locking groove under the action of an external force, the locking hook rotates to the initial position along the first direction, and during the rotation, the locking hook pushes the limiting member to separate the first locking position and the second locking position, and the locking member rotates to the initial position along the second direction.
