[0050] Example

[0051] Please see Figure 1 , Figure 1 The diagram shown is a structural schematic of the packaging device 100 provided in this embodiment.

[0052] The packaging device 100 provided in this embodiment is used for packaging goods, which are typically stacked. By using this packaging device 100 to package stacked goods, the stacked goods can be locked in place, preventing them from loosening. In practical applications, multiple packaging devices 100 are usually used in combination to lock multiple parts around the goods, ensuring a stable locking state.

[0053] The packaging device 100 provided in this embodiment includes a movable component 110, a first locking member 120, and a second locking member 130. The first locking member 120 and the second locking member 130 are used to clamp the opposite ends of the goods, typically the opposite ends in the stacking direction. The movable component 110 is connected to the first locking member 120 and the second locking member 130 respectively, and is used to adjust the distance between the first locking member 120 and the second locking member 130 to lock or release the goods.

[0054] When the goods are a stack of photovoltaic modules 210, applying force to the movable component 110 clamps the photovoltaic modules 210 together with the first locking member 120 and the second locking member 130, thus completing the rapid packaging of the photovoltaic modules 210. When disassembly is required, applying force to the movable component 110 increases the distance between the first locking member 120 and the second locking member 130, thereby releasing the photovoltaic modules 210.

[0055] As can be seen, the packaging device 100 provided in this embodiment can conveniently and quickly package a batch of photovoltaic modules 210, saving time and effort, and can also be recycled.

[0056] Please refer to the following: Figure 2 , Figure 2 The diagram shown is a structural schematic of the active component 110.

[0057] The movable component 110 includes a pull rod 111 and a locking device 112. A first locking member 120 is connected to the pull rod 111, and the locking device 112 is hinged to one end of the pull rod 111. A second locking member 130 is slidably sleeved on the pull rod 111 and is located between the first locking member 120 and the locking device 112.

[0058] The locking device 112 has an unlocked state and a locked state, and can rotate relative to the pull rod 111 under the action of external force, thereby switching between the unlocked state and the locked state. When the first locking member 120 and the second locking member 130 are respectively at opposite ends of the goods, during the process of the locking device 112 rotating from the unlocked state to the locked state relative to the pull rod 111 under the action of external force, it pushes the second locking member 130 closer to the first locking member 120 until the first locking member 120 and the second locking member 130 clamp the goods between them, thus completing the packaging of the goods.

[0059] When it is necessary to disassemble the packaged goods, a force is applied to the locking device 112 to switch it from the locked state to the unlocked state. The locking device 112 releases its resistance to the second locking member 130, allowing the distance between the second locking member 130 and the first locking member 120 to be expanded under force, thereby releasing the goods from the lock between them and realizing the release of the goods.

[0060] In this embodiment, a stop portion 1111 is provided at the end of the pull rod 111 away from the locking device 112. The first locking member 120 is slidably sleeved on the pull rod 111 and is located between the second locking member 130 and the stop portion 1111.

[0061] Understandably, the locking device 112 is used to prevent the second locking member 130 from slipping off the end of the pull rod 111 away from the stop portion 1111, and the stop portion 1111 is used to prevent the first locking member 120 from slipping off the end of the pull rod 111 away from the locking device 112. In other words, the first locking member 120 and the second locking member 130 can only slide between the stop portion 1111 and the locking device 112.

[0062] Taking photovoltaic module 210 as an example, in practical applications, multiple photovoltaic modules 210 are stacked sequentially between the first locking member 120 and the second locking member 130. As the stacking degree increases, the distance between the first locking member 120 and the second locking member 130 is continuously adjusted, that is, the first locking member 120 is adjusted to slide closer to the stop part 1111, and the second locking member 130 is adjusted to slide closer to the locking device 112. When multiple photovoltaic modules 210 are stacked, the locking device 112 is rotated to the locking state to clamp the stacked structure of multiple photovoltaic modules 210.

[0063] In another embodiment, the first locking member 120 may also be fixedly connected to the end of the pull rod 111 away from the locking device 112. The connection method can be welding, bonding, etc., and the first locking member 120 and the pull rod 111 can also be an integrally formed structure. In this case, the position of the first locking member 120 on the pull rod 111 is fixed, and during the process of the locking device 112 switching to the locking state, the second locking member 130 is pushed to slide along the pull rod 111 close to the first locking member 120.

[0064] In fact, in this embodiment, the locking device 112 is provided with a release part 1121 and a pressing part 1122. In the unlocked state, the release part 1121 stops the second locking member 130. In the locked state, the pressing part 1122 stops the second locking member 130. The distance between the release part 1121 and the rotation center line of the locking device 112 is less than the distance between the pressing part 1122 and the rotation center line.

[0065] Since the distance between the hinged position of the locking device 112 and the pull rod 111 and the stop part 1111 remains fixed, the distance between the release part 1121 and the rotation center line of the locking device 112 is less than the distance between the abutment part 1122 and the rotation center line. In the unlocked state, the distance between the release part 1121 and the stop part 1111 is larger, that is, the maximum distance between the first locking member 120 and the second locking member 130 is larger. In the locked state, the distance between the abutment part 1122 and the stop part 1111 is smaller, that is, the maximum distance between the first locking member 120 and the second locking member 130 is smaller.

[0066] Understandably, in order for the locking device 112 to be able to push the second locking member 130 closer to the first locking member 120 a certain distance during the process of rotating from the unlocked state to the locked state, it is necessary to ensure that the locking device 112 is in a resisting state with the second locking member 130 before rotating to the locked state.

[0067] At the beginning of rotation, when the release part 1121 stops the second locking member 130, the release part 1121 can be in contact with the second locking member 130, or there can be a certain gap between the two. However, the gap between the two cannot exceed the difference between the distance between the pressing part 1122 and the release part 1121 and the rotation center line, so as to ensure that when the pressing part 1122 stops the second locking member 130, the locking device 112 has pushed the second locking member 130 close to the first locking member 120 by a certain distance.

[0068] Please refer to the following: Figure 3 , Figure 3 The diagram shown is a structural schematic of the locking device 112.

[0069] As can be seen, in this embodiment, the locking device 112 pushes the second locking member 130 to slide during the rolling process on the surface of the second locking member 130, thereby realizing the switch from the unlocked state to the locked state. To ensure a smooth and stable switching process, it is necessary to ensure that the locking device 112 can roll smoothly and stably on the surface of the second locking member 130. For this reason, in this embodiment, the locking device 112 has an arc-shaped rolling sidewall 1123, and the release part 1121 and the abutment part 1122 are distributed at intervals on the rolling sidewall 1123.

[0070] Specifically, the rolling sidewall 1123 is a convex arc surface on the surface of the locking member 112, achieving a smooth transition between the release part 1121 and the abutment part 1122. During the rotation of the locking member 112 from the unlocked state to the locked state, the rolling sidewall 1123 can contact and roll with the surface of the second locking member 130, ensuring a stable rolling process without sudden stroke changes, thereby ensuring a smooth and stable state switching process.

[0071] Furthermore, in this embodiment, the rolling sidewall 1123 is actually an elliptical arc, that is, in a plane perpendicular to the rotation center line, the projection of the rolling sidewall 1123 is an elliptical arc. The release part 1121 is located at one end of the minor axis of the elliptical arc, and the abutment part 1122 is located at one end of the major axis of the elliptical arc. The distance between the release part 1121 and the rotation center line of the locking device 112 is... Figure 3 In the figure, the distance between the L-shaped abutment 1122 and the rotation center line is... Figure 3 H in the text.

[0072] Understandably, since the release part 1121 is located at one end of the short axis of the elliptical arc, when the release part 1121 is in contact with the second locking member 130, the tangent at the release part 1121 is perpendicular to the axis of the pull rod 111. That is, when no external force is applied, the locking device 112 can maintain this stable state.

[0073] Similarly, since the abutting part 1122 is located at one end of the major axis of the elliptical arc, when the abutting part 1122 is in contact with the second locking member 130, the tangent at the abutting part 1122 is also perpendicular to the axis of the pull rod 111. Under the condition that no external force is applied, the locking device 112 can also maintain this stable state.

[0074] In other words, in this embodiment, the rolling sidewall 1123 of the locking device 112 is set as an elliptical arc, which not only ensures a smooth and stable state switching process, but also ensures that the unlocked state and the locked state can be maintained relatively stably.

[0075] Please continue reading. Figure 3 In this embodiment, the locking device 112 includes a rotating body 1124 and an operating handle 1125. One end of the pull rod 111 away from the stop 1111 is hinged to the rotating body 1124, and the rotating body 1124 stops the second locking member 130. One end of the operating handle 1125 is connected to the rotating body 1124 and is used to drive the rotating body 1124 to rotate relative to the pull rod 111 under the action of external force.

[0076] The rolling sidewall 1123 is disposed on the rotating body 1124, meaning that the projection of the rotating body 1124 in the plane perpendicular to the rotation center line of the locking device 112 is an elliptical structure. In the unlocked state, the second locking member 130 is stopped at one end of the rotating body 1124 corresponding to the short axis of the elliptical structure, i.e., the release part 1121 stops the second locking member 130. In the locked state, the second locking member 130 is stopped at one end of the rotating body 1124 corresponding to the long axis of the elliptical structure, i.e., the abutment part 1122 stops the second locking member 130.

[0077] To further improve the stability of the rotation process of the rotating body 1124, in this embodiment, a clearance groove 1126 is provided on the side wall of the rotating body 1124. The plane on which the extension trajectory of the clearance groove 1126 lies is perpendicular to the rotation center line of the locking device 112. One end of the pull rod 111 extends into the clearance groove 1126 and is hinged to the two side walls of the clearance groove 1126. In fact, in this embodiment, a rotating shaft is provided between the two side walls of the clearance groove 1126, and one end of the pull rod 111 is connected to the rotating shaft.

[0078] It is understandable that the process of rotating the main body 1124 by operating the handle 1125 is equivalent to the process of the pull rod 111 swinging within the relief groove 1126. The relief groove 1126 provides clearance for the swinging of the pull rod 111. The relief groove 1126 is formed on the rolling side wall 1123, which is equivalent to dividing the rolling side wall 1123 into two parts. Both parts of the rolling side wall 1123 on both sides of the relief groove 1126 are in contact with and roll on the surface of the second locking member 130, ensuring that the rotating main body 1124 is subjected to balanced force and further improving the stability of the rotation process.

[0079] Please refer to the following: Figure 4 and Figure 5 , Figure 4 The diagram shown is a structural schematic of the first locking element 120. Figure 5 The diagram shown is a structural schematic of the second locking element 130.

[0080] In this embodiment, the first locking member 120 includes a first clamping plate 122 and a first limiting plate 123. The first clamping plate 122 and the first limiting plate 123 are connected at an angle. The first clamping plate 122 is used to clamp the opposite ends of the goods with the second locking member 130. The first limiting plate 123 is connected to the pull rod 111 and is located on the side of the first clamping plate 122 near the second locking member 130. The first limiting plate 123 is used to cooperate with the side wall of the goods to limit the first clamping plate 122.

[0081] Regarding the cooperation method between the pull rod 111 and the first limiting plate 123, in this embodiment, the first limiting plate 123 is provided with a first mating hole 1231 extending from the end away from the first clamping plate 122 to the end connected to the first clamping plate 122. The pull rod 111 passes through the first mating hole 1231 and slides in cooperation with the first limiting plate 123. The end of the pull rod 111 away from the locking device 112 is provided with a stop portion 1111 that stops the first locking member 120.

[0082] The stop portion 1111 is disposed at the end of the pull rod 111 away from the locking device 112, and at the end of the first limiting plate 123 away from the second locking member 130. In this embodiment, the surface of the first clamping plate 122 facing away from the second locking member 130 is flush with the surface of the first limiting plate 123 facing away from the second locking member 130. Therefore, when the stop portion 1111 abuts against the first locking member 120, the stop portion 1111 can abut against the first limiting plate 123 or against the surface of the first clamping plate 122 facing away from the second locking member 130.

[0083] Regarding the limiting effect of the first limiting plate 123 on the first clamping plate 122, it can be understood that when the first clamping plate 122 is in contact with the end wall of the cargo, the first limiting plate 123 extends on one side wall of the cargo. Because the pull rod 111 cooperates with the first limiting plate 123, under the action of the locking device 112 pulling the pull rod 111, the first clamping plate 122 tends to flip towards the side where the first limiting plate 123 is located. The first limiting plate 123 can abut against the side wall of the cargo, thereby counteracting the flipping tendency of the first clamping plate 122 and ensuring structural stability.

[0084] It should be noted that in the embodiment where the first locking member 120 is fixedly connected to the pull rod 111, the end of the pull rod 111 away from the locking device 112 can be fixedly connected to the end of the first limiting plate 123 away from the first clamping plate 122, and the pull rod 111 can also be integrally formed with the first clamping plate 122.

[0085] Furthermore, in this embodiment, the first locking member 120 is actually a corner protection structure, with two first limiting plates 123. The two first limiting plates 123 are vertically erected on the same side of the first clamping plate 122, and are perpendicular to each other and connected. That is, the two first limiting plates 123 and the first clamping plate 122 together form a trihedral angle space. In practical applications, the first locking member 120 is used to cover the top corner of the goods, protecting the top corner of the goods while simultaneously locking them in place with the second locking member 130.

[0086] Correspondingly, in this embodiment, there are also two movable components 110. The two pull rods 111 corresponding to the two movable components 110 are arranged in parallel. The two first limiting plates 123 can be slidably sleeved on the two pull rods 111 corresponding to the two movable components 110. The second locking member 130 can be slidably sleeved on the multiple pull rods 111 corresponding to the two movable components 110.

[0087] In another embodiment, the number of the first limiting plate 123 and the movable component 110 can be adjusted according to the actual application conditions to adapt to the surface contours of different goods, and the multiple first limiting plates 123 may not be connected to each other.

[0088] In fact, in this embodiment, the structures of the first locking member 120 and the second locking member 130 are basically the same. Specifically, the second locking member 130 includes a second clamping plate 132 and a second limiting plate 133. The second clamping plate 132 and the second limiting plate 133 are connected at an angle. The second clamping plate 132 is used to clamp the opposite ends of the goods with the first locking member 120. The second limiting plate 133 is slidably sleeved on the pull rod 111 and is located on the side of the second clamping plate 132 near the first locking member 120. The second limiting plate 133 is used to cooperate with the side wall of the goods to limit the second clamping plate 132.

[0089] Similarly, the second limiting plate 133 is provided with a second mating hole 1331 extending from the end away from the second clamping plate 132 to the end connected to the second clamping plate 132, and the pull rod 111 passes through the second mating hole 1331.

[0090] Furthermore, the surface of the second clamping plate 132 facing away from the first locking member 120 is flush with the surface of the second limiting plate 133 facing away from the first locking member 120. Therefore, during the process of the locking device 112 switching from the unlocked state to the locked state, its rotating body 1124 can roll either on the surface of the second limiting plate 133 facing away from the first locking member 120 or on the surface of the second clamping plate 132 facing away from the first locking member 120.

[0091] Regarding the limiting effect of the second limiting plate 133 on the second clamping plate 132, it can be understood that when the second clamping plate 132 is in contact with the end wall of the cargo, the second limiting plate 133 extends on one side wall of the cargo. Similarly, due to the cooperation between the pull rod 111 and the second limiting plate 133, the second clamping plate 132 tends to flip towards the side where the second limiting plate 133 is located when the locking device 112 pulls the pull rod 111. The second limiting plate 133 can abut against the side wall of the cargo to counteract the flipping tendency of the second clamping plate 132 and ensure structural stability.

[0092] In this embodiment, the second locking member 130 is also a corner protection structure. It has two second limiting plates 133, both of which are slidably fitted onto the two pull rods 111 corresponding to the two movable components 110. The two second limiting plates 133 are vertically erected on the same side of the second clamping plate 132, and are perpendicular to each other and connected, forming a trihedral angle space together with the second clamping plate 132. The second locking member 130 also covers the other top corner of the goods, thus protecting the top corner of the goods.

[0093] In another embodiment, the number of the second limiting plate 133 and the movable component 110 can also be adjusted according to the actual application conditions to adapt to the surface contours of different goods, and the multiple second limiting plates 133 may not be connected to each other.

[0094] It should be noted that in this embodiment, the first locking member 120 and the second locking member 130 have basically the same structure. In another embodiment, the structures of the first locking member 120 and the second locking member 130 may also be different.

[0095] Furthermore, to prevent damage to the goods during the packaging process, in this embodiment, the surface of the first locking member 120 is provided with a first buffer layer 121 for contacting the goods. In fact, the first buffer layer 121 is disposed on the cavity wall of the included angle space formed by the first clamping plate 122 and the two first limiting plates 123. The surface of the second locking member 130 is provided with a second buffer layer 131 for contacting the goods. Similarly, the second buffer layer 131 is also disposed on the cavity wall of the included angle space formed by the second clamping plate 132 and the two second limiting plates 133.

[0096] In this embodiment, both the first buffer layer 121 and the second buffer layer 131 are made of cotton. In other embodiments, materials such as rubber can also be selected according to the actual application conditions.

[0097] In summary, the packaging device 100 provided in this embodiment can conveniently and quickly package various goods, including batches of photovoltaic modules 210, saving time and effort, and can also be recycled.

[0098] In addition, this embodiment also provides a photovoltaic module packaging structure 200, please refer to [link / reference]. Figure 6 , Figure 6 The diagram shown is a partial structural schematic of the photovoltaic module packaging structure 200.

[0099] The photovoltaic module packaging structure 200 provided in this embodiment includes multiple photovoltaic modules 210 and multiple packaging devices 100. The multiple photovoltaic modules 210 are stacked sequentially to form a stacked structure. The multiple packaging devices 100 are distributed around the periphery of the stacked structure. Each locking device 112 is in a locked state. The first locking member 120 and the second locking member 130 of each locking device 112 clamp the stacked structure in the stacking direction of the multiple photovoltaic modules 210.

[0100] Specifically, the stacking structure has multiple diagonal groups, each diagonal group including two corresponding apex corners in the stacking direction, multiple packing devices 100 correspond one-to-one with multiple diagonal groups, and the first locking member 120 and the second locking member 130 corresponding to each packing device 100 respectively cover the two apex corners of the diagonal group.

[0101] Please refer to the following: Figure 7, Figure 7 The diagram shown is another part of the photovoltaic module packaging structure 200.

[0102] In fact, the photovoltaic module packaging structure 200 provided in this embodiment also includes a tray 220, a lower cover 230, a middle frame 240, and an upper cover 250. The tray 220 supports the stacked structure formed by multiple photovoltaic modules 210. After the stacked structure is locked by multiple packaging devices 100, the tray 220 and the stacked structure are placed on the lower cover 230, the middle frame 240 is fitted around the perimeter of the stacked structure, and finally the upper cover 250 is placed on top of the middle frame 240 to complete the packaging process.

[0103] Benefiting from the beneficial effects of the packaging device 100, the photovoltaic module packaging structure 200 provided in this embodiment also has the characteristics of simple and convenient packaging operation, saving time and effort.
