Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In some examples, a solar device may include a solar panel and a bracket assembly. Solar power can be used to convert light energy into electrical energy. The solar panel may be disposed on the bracket assembly and its orientation adjusted by the bracket assembly.

The bracket assembly may include a carrier and a support bracket. The bearing frame is used for bearing the solar panel. The supporting frame is rotatably connected with the bearing frame so as to rotate relative to the bearing frame and adjust the included angle between the supporting frame and the bearing frame.

The present inventors have long studied and found that in the related art, there is a certain friction between the carrier and the support frame, which can be used to act on the carrier so that the carrier can support the solar panel within a preset angle; if the angle of the carrier and the support frame is to be adjusted to adjust the orientation of the solar panel, a force needs to be applied between the carrier and the support frame to overcome the friction force so as to rotate the carrier and the support frame relative to each other. However, the carrier and the support frame may wear during rotation, which may lead to failure of the bracket assembly, and may eventually manifest itself as insufficient friction to support the solar panel at a predetermined angle during use. In order to solve the above technical problems, the present utility model proposes the following embodiments.

The following inventive bracket assembly embodiments describe exemplary configurations of a bracket assembly for a solar panel.

Referring to fig. 1, 2, 3 and 4, the bracket assembly 1 may further include a carrier 10, a support bracket 20, a rotation shaft assembly 30 and a rotation stopping assembly 40.

The rotation shaft assembly 30 may connect the carrier 10 and the support frame 20 such that the support frame 20 is rotatably connected to the carrier 10 through the rotation shaft assembly 30. The anti-rotation assembly 40 may be provided to the carrier 10 or the support frame 20 with a locked state and an unlocked state. The rotation stopping assembly 40 is in limit connection with the rotating shaft assembly 30 in the locking state so as to limit the relative rotation between the bearing frame 10 and the supporting frame 20. The anti-rotation assembly 40 unlocks the limited connection with the spindle assembly 30 in the unlocked state to allow the carrier 10 and the bracket to rotate relative to each other through the spindle assembly 30.

Unlike the related art case, the carrier 10 and the support frame 20 can be relatively rotated by the rotation shaft assembly 30; in addition, when the angle between the carrier 10 and the support frame 20 is not required to be adjusted, the rotation stopping assembly 40 can be set to be in a locking state so as to limit the rotation of the rotating shaft assembly 30, and then a preset angle can be formed between the carrier 10 and the solar panel, when the angle between the carrier 10 and the support frame 20 is required to be adjusted, the rotation stopping assembly 40 and the rotating shaft assembly 30 can be disconnected from limiting connection, the rotating shaft assembly 30 can be adjusted relatively independently, and the friction between the rotating shaft assembly 30 and the rotation stopping assembly 40 is reduced, so that the possibility of abrasion of the bracket assembly 1 due to friction is reduced.

Referring to fig. 5, 6 and 7, the rotation shaft assembly 30 is fixed to the support frame 20 and rotatably coupled to the carrier 10. The rotation shaft assembly 30 can rotate to enable the support frame 20 and the bearing frame 10 to rotate relatively. The rotation stopping assembly 40 is disposed on the carrier 10 and is in limiting connection with the rotating shaft assembly 30 in a locked state to limit the rotating shaft assembly 30 to rotate relative to the carrier 10, and in an unlocked state to allow the rotating shaft assembly 30 to rotate relative to the carrier 10.

Optionally, a rotation stop assembly 40 is movably arranged to the carrier 10 (see fig. 4) to be movable relative to the carrier 10 for switching between a locked state and an unlocked state.

Referring to fig. 8 and 9, an end of the rotation stopping assembly 40 facing the rotation shaft assembly 30 may be provided with a first stopper 410. At least two second limiting portions 310 are circumferentially disposed at one end of the rotation shaft assembly 30 facing the rotation stop assembly 40. The spindle assembly 30 is rotatable relative to the anti-rotation assembly 40 such that the first stop portion 410 is connectable with any one of the at least two second stop portions 310. When the first limiting portions 410 are sequentially connected to the two at least second limiting portions 310, the angle between the supporting frame 20 and the carrier 10 may be changed.

Optionally, when the anti-rotation assembly 40 is in the locked state, the first limiting portion 410 is in limiting connection with any one of the at least two second limiting portions 310. When the rotation stopping assembly 40 is in the unlocked state, the first limiting portion 410 and the second limiting portion 310 are separated to allow the rotation shaft assembly 30 to rotate relative to the carrier 10.

Optionally, the anti-rotation assembly 40 includes a moveable member 41. In other examples, moveable member 41 may also be referred to as a dental tray. The end of the movable member 41 facing the rotation shaft assembly 30 may be provided with a first limiting portion 410. The movable member 41 is movably disposed on the carrier 10. The movable member 41 is movable relative to the carrier 10 to move toward and away from the spindle assembly 30 to switch the spindle assembly 30 between the locked and unlocked states.

Specifically, when the movable member 41 approaches the rotating shaft assembly 30, the first limiting portion 410 may be connected to the second limiting portion 310 of the rotation stopping assembly 40, that is, the rotating shaft assembly 30 is switched to the locked state. When the movable member 41 is away from the rotating shaft assembly 30, the first and second limiting portions 410 and 310 are disconnected, that is, the rotating shaft assembly 30 is switched to the unlocked state.

Optionally, the first limiting portion 410 is provided as a protrusion. The second stopper 310 is provided as a groove. The first limiting portion 410 and the second limiting portion 310 are in a male-female fit.

Alternatively, the rotating shaft assembly 30 forms a spacing portion 311 between two adjacent second limiting portions 310. That is, at least two second limiting portions 310 are disposed at one end of the rotating shaft assembly 30 at intervals around the axis of the rotating shaft assembly 30. In addition, the number of the second limiting parts 310 may be 2 to 50. The more the number of the second limiting portions 310 is, the more the angle can be formed between the carrier 10 and the supporting frame 20, which is beneficial to adjusting the orientation of the solar panel. In addition, at least two second limiting portions 310 may be uniformly spaced around the axis of the rotary shaft assembly 30.

Optionally, the end of the first stopper 410 (the end facing the second stopper 310) is provided with a first guide slope 411. The first guiding inclined surface 411 is used for abutting against the spacing portion 311 to guide the first limiting portion 410 to be inserted into the second limiting portion 310 adjacent to the spacing portion 311.

Optionally, the distal end of the spacer 311 is provided with a second guiding inclined surface 312 (facing one end of the first limiting portion 410), and the second guiding inclined surface 312 is used to abut against the first limiting portion 410, so as to guide the first limiting portion 410 to be inserted into the second limiting portion 310 adjacent to the spacer 311.

In this case, the first guide inclined surface 411 of the first stopper 410 and the second guide inclined surface 312 of the spacer 311 can effectively guide the first stopper 410 and the second stopper 310 to be in stopper connection, reducing the possibility of misalignment of the first stopper 410 and the second stopper 310. The first guide inclined surface 411 and the second guide inclined surface 312 may be flat surfaces or curved surfaces.

Optionally, the anti-rotation assembly 40 includes an elastic member 42. The elastic member 42 may be used to store energy during the movement of the movable member 41 away from the spindle assembly 30 and release the energy to push the movable member 41 closer to the spindle assembly 30. In other words, the elastic member 42 may be deformed to store energy during the switching of the spindle assembly 30 from the locked state to the unlocked state, and release energy to push the spindle assembly 30 closer to the spindle assembly 30 to switch from the unlocked state to the locked state.

Alternatively, the elastic member 42 is abutted between the movable member 41 and the carrier 10, and is configured to elastically expand and contract as the movable member 41 moves relative to the carrier 10. When the rotation stopping assembly 40 is switched from the locked state to the unlocked state, the movable member 41 is away from the rotating shaft assembly 30, so that the elastic member 42 is in an elastically compressed state. The elastic member 42 is configured to drive the movable member 41 to approach the rotating shaft assembly 30 through the elastic restoring state, so that the rotation stopping assembly 40 is switched from the unlocked state to the locked state.

Alternatively, the movable member 41 is spaced from and disposed opposite one end of the shaft assembly 30. The number of the first limiting parts 410 is at least two. The at least two first limiting portions 410 are disposed at intervals around the axis of the rotating shaft assembly 30, and are disposed in one-to-one correspondence with the at least two second limiting portions 310. For example, the number of the second limiting parts 310 is 10, and the number of the first limiting parts 410 may be 10 accordingly. When the anti-rotation assembly 40 is in the locked state, the at least two first limiting portions 410 are in one-to-one corresponding limiting connection with the at least two second limiting portions 310.

In other examples, the at least two first limiting parts 410 may not correspond to the at least two second limiting parts 310 one to one, for example, the number of the second limiting parts 310 may be 36, and the number of the first limiting parts 410 may be 3.

Alternatively, the rotation stop assembly 40 is spaced from and disposed opposite one end of the spindle assembly 30. The rotation stopping assembly 40 is movable with respect to the carrier 10 in the axial direction of the rotation shaft assembly 30 to be close to or away from one end of the rotation shaft assembly 30. The rotating shaft assembly 30 is abutted with one end of the rotating shaft assembly 30 and limited to each other in the locking state, and is separated from one end of the rotating shaft assembly 30 in the unlocking state.

Optionally, the bracket assembly 1 comprises a drive 50. The driving member 50 is movably disposed on the carrier 10, and the driving member 50 is connected to the rotation stopping assembly 40 and configured to move relative to the carrier 10 to drive the rotation stopping assembly 40 to move relative to the carrier 10 along the axial direction of the rotating shaft assembly 30.

Referring to fig. 10 and 11, the driving member 50 is provided in a shaft shape. The rotating shaft assembly 30 is in a cylindrical shape and sleeved on the driving piece 50, and the rotating shaft assembly 30 can rotate around the axis of the driving piece 50 relative to the driving piece 50. The driving member 50 and the shaft assembly 30 are relatively movable in the axial direction of the driving member 50. The driving member 50 is movably supported on the carrier 10 and is movable along its axis relative to the carrier 10.

In other words, the driving member 50 may be disposed on the carrier 10, and the rotation shaft assembly 30 and the support frame 20 may rotate around the driving member 50, thereby enabling the relative movement of the support frame 20 and the carrier 10.

Alternatively, one end of the driving member 50 abuts against the rotation stopping assembly 40, so as to drive the rotation stopping assembly 40 to move along the axial direction of the driving member 50, so as to be close to or far away from one end of the rotating shaft assembly 30. One end of the spindle assembly 30 is disposed opposite the anti-rotation assembly 40. The rotation stopping assembly 40 abuts against one end of the rotating shaft assembly 30 and is limited to each other in the locked state, and is separated from one end of the rotating shaft assembly 30 in the unlocked state.

Alternatively, the other end of the driving member 50 is exposed to the outside of the carrier 10 for the user to push or pull the driving member so that the driving member moves in its axial direction.

Optionally, the driving member 50 has a rotation stopping protrusion 51 at one end for being inserted into the rotation stopping assembly 40 to limit the rotation of the rotation stopping assembly 40 when the rotation stopping assembly 40 is in the locked state, and an anti-releasing protrusion 52 at the other end for limiting the driving member 50 when the rotation shaft assembly 30 is in the locked state. The drop-off preventing protrusions 52 may abut against the carrier 10 to be in frictional contact with the carrier 10. In addition, the bearing frame 10 may further be provided with an anti-falling groove, and the anti-falling protrusion 52 may be clamped in the anti-falling groove. In this case, the driving member 50 may be fixed to the carrier 10 by friction or a snap-fit action, reducing the possibility of the driving member 50 rotating.

Optionally, the bracket assembly 1 comprises a damping member 60. The damping member 60 is fixedly disposed on the carrier 10 and abuts against the other end of the rotating shaft assembly 30, and is used for contacting and rubbing with the rotating shaft assembly 30 during the rotation of the rotating shaft assembly 30 to provide damping.

Optionally, the bracket assembly 1 further includes a first rotating shaft 31 and a second rotating shaft 32 coaxially and at intervals, the first rotating shaft 31 is used for being in limiting connection with the rotation stopping assembly 40, and the second rotating shaft 32 abuts against the damping member 60, so that friction occurs between the second rotating shaft 32 and the damping member 60 when the second rotating shaft 32 rotates along with the bracket assembly 1.

Optionally, the support bracket 20 may further include a support bracket body 21 and a support bracket cover 22. The rotation shaft assembly 30 (the first rotation shaft 31 and the second rotation shaft 32) may be fixed to the support frame body 21. The support frame cover 22 may cover the support frame body 21 and the rotation shaft assembly 30. That is, the support frame 20 may be an assembled structure, whereby the assembly of the bracket assembly 1 can be facilitated. In other examples, the support frame 20 may also be a unitary structure.

In summary, in the present utility model, the user may push the rotation stopping assembly 40 to move along the axial direction thereof through the push-pull rod, so that the rotation stopping assembly 40 and the rotating shaft assembly 30 are separated, and the rotating shaft assembly 30 is in the unlocked state. In this case, the rotation shaft assembly 30 is disconnected from the limit connection with the rotation stop assembly 40, and the user can rotate the support frame 20 to adjust the angle of the support frame 20 and the carrier 10. In addition, after the damper 60 and the second rotating shaft 32 are added, the user can feel a damping sense when rotating the support, thereby improving the user's debugging feeling.

When the user removes the acting force acting on the push-pull rod, the rotation stopping assembly 40 pushes the rotation stopping assembly 40 to be close to the rotating shaft assembly 30 under the reset action of the spring, so that the rotation stopping assembly 40 is in limit connection with the rotating shaft assembly 30, and the rotating shaft assembly 30 is in a locking state. In the locked state, the rotation stopping assembly 40 and the driving member 50 are fixed to the carrier 10, and the rotating shaft assembly 30 and the rotation stopping assembly 40 are in limited connection, so that the angle between the carrier 10 and the supporting frame 20 can be maintained.

In summary, in the present utility model, the carrier 10 and the support frame 20 can rotate relatively through the rotation shaft assembly 30; in addition, when the angle between the carrier 10 and the support frame 20 is not required to be adjusted, the rotation stopping assembly 40 can be set to be in a locking state so as to limit the rotation of the rotating shaft assembly 30, and then a preset angle can be formed between the carrier 10 and the solar panel, when the angle between the carrier 10 and the support frame 20 is required to be adjusted, the rotation stopping assembly 40 and the rotating shaft assembly 30 can be disconnected from limiting connection, the rotating shaft assembly 30 can be adjusted relatively independently, and the friction between the rotating shaft assembly 30 and the rotation stopping assembly 40 is reduced, so that the possibility of abrasion of the bracket assembly 1 due to friction is reduced.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
