[0032] Embodiments of the present disclosure provide a support frame, which is characterized by comprising: a first guiding mechanism, a second guiding mechanism, and a support steering mechanism, wherein the support steering mechanism includes a first support rod, a second support rod, and a bearing member;

[0033] The first support rod has a first connecting portion and a second connecting portion which are arranged at intervals. The first connecting portion is cooperatively arranged with the first guiding mechanism. The first connecting portion can move along a first direction based on the first guiding mechanism, and the first connecting portion can rotate along the extending direction of the second support rod;

[0034] The second support rod is fixedly connected to the second connecting portion and the bearing member. The second support rod is cooperatively arranged with the second guiding mechanism. The second support rod can move along a second direction intersecting the first direction based on the second guiding mechanism, and the second support rod can rotate around its extending direction.

[0035] In this support frame, a first guiding mechanism, a second guiding mechanism, a first support rod, a second support rod, and a bearing member are provided. The first connecting portion of the first support rod moves along the first direction. The second connecting portion is fixedly connected to the second support rod, and the second support rod moves along a second direction intersecting the first direction. Among them, when the first connecting portion moves along the first direction, since there is a fixed distance between the first connecting portion and the second connecting portion, the second connecting portion will drive the second support rod to move toward the second direction. Moreover, the orientation of the first support rod also changes as the first connecting portion and the second connecting portion move. Therefore, the first connecting portion and the second connecting portion drive the second support rod to rotate along the extending direction of the second support rod, and the second support rod drives the bearing member to perform a rotating action. Therefore, by driving the first support rod to move along the first direction, the bearing member can be driven to complete a rotating action, thereby driving the orientation of the device carried by the bearing member to change. This movement process can effectively save the workload and working time of device installation by directly adjusting the orientation of the bearing member without separating the support frame from the device it carries.

[0036] Figure 1 It is a schematic structural diagram of a support frame in the present disclosure. Refer to Figure 1As shown, a support frame includes: a first guiding mechanism, a second guiding mechanism, and a support steering mechanism. The support steering mechanism includes a first support rod 110, a second support rod 120, and a bearing member 130.

[0037] Referring to Figure 1 As shown, the first support rod 110 has a first connecting portion 111 and a second connecting portion 112 arranged at intervals. The first connecting portion 111 is cooperatively arranged with the first guiding mechanism. The first connecting portion 111 can move along a first direction based on the first guiding mechanism, and the first connecting portion 111 can rotate along the extending direction of the second support rod 120. The second support rod 120 is fixedly connected to the second connecting portion 112 and the bearing member 130. The second support rod 120 is cooperatively arranged with the second guiding mechanism. The second support rod 120 can move along a second direction intersecting the first direction based on the second guiding mechanism, and the second support rod 120 can rotate around its extending direction.

[0038] Referring to Figure 1 As shown, in some examples of this embodiment, the first connecting portion 111 and the second connecting portion 112 can be respectively located at two ends of the first support rod 110 to avoid redundancy and simplify the overall structure of the support frame. In other embodiments, the first connecting portion 111 and the second connecting portion 112 can also be located in the middle of the first support rod 110.

[0039] Figure 2 is Figure 1 an enlarged structural schematic diagram of area A in Figure 1 and Figure 2 As shown, in some examples of this embodiment, a first guiding groove 201 is provided in the first guiding mechanism. The first guiding groove 201 extends along the first direction. The first guiding mechanism includes a first sliding member 210. The first sliding member 210 is arranged in the first guiding groove 201 and can move along the first guiding groove 201. The first connecting portion 111 is rotatably connected to the first sliding member 210. Among them, the first guiding groove 201 has a guiding effect and a limiting effect on the first sliding member 210, and can ensure that the first sliding member 210 slides stably along the first guiding groove 201. In other embodiments, the first guiding mechanism can also use a slide rail, etc. for guiding, but the combination of the first guiding groove 201 and the first sliding member 210 has the advantage of simpler structure.

[0040] Combined with Figure 1 and Figure 2As shown, in some examples of this embodiment, the first sliding member 210 includes a slider 211 and a rotating shaft 212 connected to the slider 211. The rotating shaft 212 passes through the first connecting portion 111, and the extending direction of the rotating shaft 212 is parallel to the extending direction of the second support rod 120. Among them, the slider 211 can be arranged in the first guiding groove 201 and slide along the first guiding groove 201. During the movement of the slider 211, it can drive the rotating shaft 212, and further drive the first connecting portion 111 to move. And the first connecting portion 111 can also rotate synchronously around the rotating shaft 212 during the movement. The design of connecting the slider 211 and the rotating shaft 212 is also beneficial to simplify the structure of the first guiding mechanism.

[0041] Combined with Figure 1 and Figure 2 As shown, in some examples of this embodiment, the first guiding mechanism further includes a plug pin 220. The plug pin 220 is detachably inserted through the first sliding member 210, and the plug pin 220 is detachably inserted into the groove wall of the first guiding groove 201. Among them, the plug pin 220 is used to fix the position of the first sliding member 210 in the first guiding groove 201, and further enable the first support rod 110 to stay fixed at a certain position. When the angle of the device needs to be adjusted, the plug pin 220 can be taken out. At this time, the first sliding member 210 can be operated to move to adjust the angle of the device. When the adjustment is completed, the plug pin 220 can be inserted again to fix the first sliding member 210 on the groove wall of the first guiding groove 201.

[0042] Figure 3 is Figure 1 the structural schematic diagram of the support frame after rotation and laying flat in Figure 3 As shown, there can be multiple first guiding mechanisms, and the multiple first guiding mechanisms are arranged at intervals. It can be understood that each first guiding mechanism can be used to support the corresponding first support rod 110, and further carry a device. Setting multiple first guiding mechanisms and correspondingly setting multiple support and steering mechanisms helps to increase the number of devices that the support frame can carry simultaneously.

[0043] And, referring to Figure 1 and Figure 3As shown, in some examples of this embodiment, the support frame further includes an operation ring 410. The first sliding members 210 in multiple said first guiding mechanisms are all connected to the operation ring 410 and are arranged inside the operation ring 410. The pins 220 in multiple said first guiding mechanisms are also insertable and removable through the operation ring 410. Among them, designing the operation ring 410 to be connected to multiple first sliding members 210 simultaneously can synchronously adjust the positions of multiple first sliding members 210, and correspondingly ensure that the angles of the devices borne by each support steering mechanism change synchronously. Setting the operation ring 410 also facilitates the actual operation of the operator.

[0044] Referring to Figure 1 and Figure 3 As shown, in some examples of this embodiment, the support frame further includes a mounting plate 430 and a telescopic column 420. The mounting plate 430 is arranged on the column 420 and is connected to the column 420. The first guiding mechanism is arranged on the side wall of the column 420, and the telescopic direction of the column 420 is parallel to the first direction. The second guiding mechanism and the second support rod 120 are both arranged on the side of the mounting plate 430 away from the column 420. A through hole penetrating through opposite sides of the mounting plate 430 is arranged in the mounting plate 430, and the first support rod 110 is inserted through the through hole.

[0045] It can be understood that in this embodiment, the column 420 is used to support the mounting plate 430. By using a telescopic column 420, the height of the mounting plate 430 of this support frame is also adjustable, and further the height of the device is adjustable. Therefore, this support frame including a telescopic column 420 can simultaneously adjust the height and angle of the device.

[0046] Furthermore, setting the first guiding mechanism on the side wall of the column 420 can support the first guiding mechanism by means of the column 420, simplify the structural design of the support frame, and also help to ensure the synchronous movement of the first guiding mechanism and the column 420.

[0047] Referring to Figure 1 and Figure 3 As shown, in some examples of this embodiment, the first guiding groove 201 in the first guiding mechanism can be arranged on the surface of the side wall of the column 420, and the direction of the first guiding groove 201 is parallel to the axial direction of the column 420.

[0048] Referring to Figure 1 and Figure 3 As shown, in some examples of this embodiment, the operation ring 410 can be sleeved on the outside of the column 420.

[0049] Referring to Figure 1 and Figure 3As shown, in some examples of this embodiment, the column 420 includes a hollow outer column and an inner column disposed in the outer column, where the inner column can telescopically move within the outer column. The first guiding mechanism can be disposed on the side wall of the outer column of the column 420.

[0050] In some examples of this embodiment, the column 420 can include a motor (not shown in the figure), and the motor is used to drive the inner column to perform telescopic movement.

[0051] Refer to Figure 1 As shown, in some examples of this embodiment, a second guiding groove 301 is provided in the second guiding mechanism. The second guiding mechanism includes a second sliding member 310. The second sliding member 310 is disposed in the second guiding groove 301 and can move along the second guiding groove 301, and the second sliding member 310 can also rotate in the second guiding groove 301. The second support rod 120 is connected to the second sliding member 310. Among them, the second guiding groove 301 has a guiding effect and a limiting effect on the second sliding member 310, and can ensure that the second sliding member 310 stably slides along the second guiding groove 301. In other embodiments, the second guiding mechanism can also use a slide rail, etc. for guiding, but the combination of the second guiding groove 301 and the second sliding member 310 has the advantage of a simpler structure.

[0052] In some examples of this embodiment, the second sliding member 310 can be a ball, and the ball can perform sliding and rolling actions in the second guiding groove 301. Since the second support rod 120 will perform a rotational action synchronously when moving, therefore, when using a ball as the second sliding member 310, the second sliding member 310 can perform a synchronous rotational action with the second support rod 120 to ensure the smooth movement of the second sliding member 310.

[0053] It can be understood that the second guiding groove 301 can be linear or curved, as long as any two parts of the second guiding groove 301 have a spacing in the second direction, thereby ensuring that the second support rod 120 can generate a displacement in the second direction. Further, in this embodiment, the second guiding groove 301 can be arc-shaped.

[0054] Refer to Figure 1 As shown, in some examples of this embodiment, the second support rod 120 can be inserted into the second connecting portion 112 of the first support rod 110 to make the connection between the two more stable and ensure uniform force. Further, the second support rod 120 can also be inserted into the carrier 130.

[0055] Figure 4 For Figure 1 Schematic diagram of the structure where the second support rod 120 in Figure 1 and Figure 4As shown, in some examples of this embodiment, the second guiding mechanism further includes a limiting plate 320, and the second support rod 120 is connected to the second sliding member 310 through the limiting plate 320. A thread 121 is provided on the second support rod 120, and a threaded hole adapted to the thread 121 on the second support rod 120 is provided in the limiting plate 320, and the second support rod 120 is detachably connected to the limiting plate 320. Wherein, the limiting plate 320 is used to limit the position of the device carried by the carrier 130, further ensuring the stable carrying of the device by this support frame. In addition, setting the threaded connection between the second support rod 120 and the limiting plate 320 helps the second support rod 120 to be inserted into the second connection part 112 of the first support rod 110 and the carrier 130 during actual use, making the assembly of this support frame easy.

[0056] Referring to Figure 1 As shown, in some examples of this embodiment, two opposite second guiding grooves 301 are provided in the second guiding mechanism, the second support rod 120 is located between the two second guiding grooves 301, and opposite ends of the second support rod 120 can move along the two second guiding grooves 301 respectively. Setting the second guiding grooves 301 at both opposite ends of the support rod can ensure the synchronous movement of both ends of the second support rod 120, which helps to make the structure of the second support rod 120 more stable.

[0057] Referring to Figure 1 As shown, in some examples of this embodiment, the second guiding mechanism may include a second guiding plate 300, and the second guiding groove 301 may be provided on the plate surface of the second guiding plate 300. Further, the second guiding plate 300 may be provided on a side of the mounting plate 430 away from the column 420.

[0058] Referring to Figure 1 As shown, in some examples of this embodiment, there may be two second guiding plates 300, the two second guiding plates 300 are arranged at intervals, and two second limiting grooves in the same second guiding mechanism may be respectively provided on opposite plate surfaces of the two second guiding plates 300.

[0059] Further, in some examples of this embodiment, corresponding to the case where there are multiple first guiding mechanisms, there are also multiple second guiding mechanisms. As Figure 1 shown, in this example, multiple second limiting grooves may be provided on the plate surface of one second guiding plate 300, and multiple second limiting grooves are correspondingly provided on the plate surface of the other second guiding plate 300.

[0060] Further, the present disclosure also provides a photovoltaic power generation device, Figure 5 which is a structural schematic diagram of a photovoltaic power generation device. Referring to Figure 5As shown, the photovoltaic power generation device includes a photovoltaic module 500 and a support frame as described in any of the above embodiments, and the photovoltaic module 500 is connected to the carrier 130 in the support frame.

[0061] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0062] The above embodiments only express several implementation manners of the present utility model, and the description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
