[0054] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0055] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0056] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0057] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0058] like Figures 1-3 As shown, this embodiment provides a fixing device 300, which is used to fix the solar panel 100 to the roof 500 of a vehicle or to a wall. It is understood that in some other embodiments, the fixing device 300 may also be used to fix other objects to the roof 500 of a vehicle or to fix the solar panel 100 to a wall. Figure 4 What is shown is a partial cross-sectional view of the fixing device 300 and the solar panel 100 in this embodiment being installed on the roof 500.

[0059] like Figure 1 As shown, in this embodiment, the fixing device 300 is mounted on the frame assembly 200. The frame assembly 200 includes a first frame (horizontally fixed) and a second frame. One side of the second frame is rotatably connected to one side of the first frame via a hinge. The second frame is used to support the solar panel 100. By adjusting the angle of the second frame relative to the first frame, the angle of the solar panel 100 relative to sunlight can be adjusted.

[0060] In order to fix the solar panel 100 to the roof 500 of the car, the roof 500 of the car has four mounting holes (not shown in the figure), and the first frame also has four mounting holes (not shown in the figure) corresponding to the four mounting holes of the roof 500.

[0061] like Figures 5-8As shown, in this embodiment, the fixing device 300 mainly includes a driving member, a fixing member 320, a driven member 340, a pressure plate 350, a first connecting member 360, a second connecting member 370, and a third connecting member 380. A solar panel 100 is mounted on the frame assembly 200.

[0062] like Figure 9 As shown, the fixing member 320 has a first end and a second end opposite to each other, and a through hole 3202 connecting the first end and the second end is provided on the fixing member 320. One end of the driving member is exposed outside the first end of the through hole 3202, and the other end of the driving member passes through the through hole 3202 and is exposed outside the second end. It can be understood that the first end of the fixing member 320 is the upper end of the fixing member 320, and the second end is the lower end of the fixing member 320. The driven member 340 is rotatably connected to the second end of the fixing member 320. The driven member 340 is configured to be driven by the other end of the driving member to open or close. That is, the driving member can drive the driven member 340 to open (first state) or close (second state). At the same time, the pressure plate 350 is movably sleeved on the fixing member 320. The pressure plate 350 can press the roof 500 or the wall, thereby improving the stability and reliability of the connection between the fixing device 300 and the roof 500 or the wall. In addition, the pressure plate 350 in this embodiment can also adjust the distance between the frame assembly 200 and the roof 500 or the wall, thereby enabling the fixing device 300 to adapt to different installation distances and improving the flexibility and applicability of the fixing device 300.

[0063] Based on the above design, when a user needs to use the fixing device 300 to install the solar panel 100, first align the fixing member 320 with the four through holes 3202 of the frame assembly 200, and then pass the driving member with the driven member 340 through the through holes 3202 of the fixing member 320, so that one end of the driving member protrudes from the end face of the frame assembly 200, and the other end passes through the mounting hole of the car roof 500, and the driven member 340 protrudes from the mounting hole of the car roof 500, which is conducive to the subsequent opening of the driven member 340. At this point, the user can rotate the driving component to open the driven component 340. Once opened, the driven component 340 can abut against the lower surface of the roof 500. Then, the user can rotate the pressure plate 350 to move it on the fixing component 320, finally allowing the pressure plate 350 to abut against the upper surface of the roof 500. This completes the installation of the solar panel 100 onto the car roof 500 using the fixing device 300 of this invention. Of course, the fixing device 300 of this invention is not only suitable for car roofs 500, but also for the facades of high-rise buildings, and other scenarios where the user can only operate from one side; these will not be elaborated upon here.

[0064] Compared with existing technologies, the fixing device 300 in this embodiment has a simple structure. Through the arrangement of the driving component, driven component 340, and fixing component 320, the user only needs to operate from one side to install the fixing device 300, meaning the user can operate it from the roof 500, saving time and effort, improving installation efficiency, and reducing costs. At the same time, this fixing device 300 can be applied to more scenarios, improving its versatility.

[0065] like Figure 9 As shown, in this embodiment, the fixing member 320 is provided with an external thread 3201, and the pressure plate 350 is provided with an internal thread 3501. The external thread 3201 and the internal thread 3501 are adapted to each other so that the fixing member 320 and the pressure plate 350 are threadedly connected, thereby realizing the movable connection between the pressure plate 350 and the fixing member 320. By rotating the pressure plate 350, the roof 500 is clamped under the action of the pressure plate 350 and the driven member 340, which improves the stability and reliability of the fixing device 300 and avoids shaking.

[0066] like Figure 10 As shown, in this embodiment, the driving component includes a first gear 330 and a knob 310. The first gear 330 meshes with a driven member 340. When the first gear 330 rotates, it can drive the driven member 340 to open (first state) or close (second state). The fixing device 300 includes a first connector 360 and a second connector 370. The first gear 330 is connected to the end of the knob 310 through the first connector 360, and the driven member 340 is connected to the second end of the fixing member 320 through the second connector 370. The driven member 340 can rotate around the second connector 370. This allows the user to rotate the knob 310, which in turn drives the first gear 330 to rotate, thereby causing the first gear 330 to open the driven member 340. At this time, the driven member 340 can abut against the inner wall of the roof 500.

[0067] Furthermore, an incomplete gear 3401 is provided at the meshing point between the driven member 340 and the first gear 330. The driven member 340 meshes with the first gear 330 through the incomplete gear 3401, thereby enabling the incomplete gear 3401 to play a certain limiting role on the driven member 340 and prevent the driven member 340 from opening excessively.

[0068] Furthermore, a washer 3701 is fitted onto the second connector 370, and the washer 3701 abuts against the end face of the knob 310. The washer 3701 ensures that the driven member 340 and the end face of the knob 310 maintain a certain gap, thereby preventing friction between the end face of the knob 310 and the driven member 340 and improving the smoothness of the driven member 340 opening or closing.

[0069] Optionally, in this embodiment, at least two followers 340 are provided, and the at least two followers 340 are arranged in an array about the axis of the first gear 330. For example... Figure 9 As shown, in this embodiment, there can be three driven members 340, arranged in an array about the axis of the first gear 330. This allows the pressure to be evenly distributed among the three driven members 340 when they open, thereby improving the stability of the fixing device 300 and extending its service life. Of course, operators can flexibly set the number of driven members 340 according to actual needs, such as two, four, or five, which will not be elaborated here.

[0070] Optionally, the follower 340 in this embodiment can be set as an arc-shaped part, which facilitates the opening or closing of the follower 340, thereby improving the smoothness and working efficiency of the opening or closing of the follower 340.

[0071] like Figure 10 As shown, in this embodiment, a boss 3301 is provided on the first gear 330, and a groove 3101 is recessed at the end of the knob 310 near the first gear 330, with the boss 3301 embedded in the groove 3101. The provision of the boss 3301 and the groove 3101 can improve the stability and reliability of the connection between the knob 310 and the first gear 330.

[0072] Furthermore, the side of the boss 3301 is provided with an outer chamfer 3302, and the groove 3101 is provided with an inner chamfer 3102. The outer chamfer 33025 and the inner chamfer 3102 are connected in a cooperative manner. This can further improve the stability of the connection between the knob 310 and the first gear 330, and avoid the problem of the first gear 330 slipping or moving out of sync when the knob 310 is rotated.

[0073] like Figure 9 As shown, in this embodiment, the fixing device 300 further includes a third connector 380, which passes between the fixing member 320 and the frame assembly 200, thereby connecting the fixing member 320 and the frame assembly 200. It should be noted that the third connector 380 does not pass through the frame assembly 200; that is, the mounting hole on the frame assembly 200 is a blind hole. This ensures that the installed third connector 380 will not contact the end face of the knob 310, thus facilitating the smooth rotation of the knob 310.

[0074] Optionally, the first connector 360, the second connector 370, and the third connector 380 in this embodiment can all be set as screws or bolts to achieve the function of fixed connection. Of course, operators can select other parts according to actual needs, and this embodiment does not limit this.

[0075] likeFigures 11-12 As shown, in this embodiment, the fixing device 300 further includes a limiting component 400, which is disposed on the frame component 200. The limiting component 400 abuts against the end face of the knob 310 so that the limiting component 400 can restrict the knob 310 from reversing.

[0076] Specifically, such as Figures 13-14 As shown, the limiting assembly 400 includes a ratchet 410 and a fourth connector 420. The fourth connector 420 passes through the ratchet 410 and is connected to the frame assembly 200. The fourth connector 420 can be a screw or bolt, etc. The ratchet 410 can rotate around the fourth connector 420, and during rotation, the ratchet 410 always abuts against the end face of the knob 310. An arc-shaped abutment portion 4101 is provided at the end of the ratchet 410 near the knob 310, and teeth 3103 are provided on the end face of the knob 310. The teeth 3103 are adapted to the arc-shaped abutment portion 4101 so that the ratchet 410 restricts the knob 310 from reversing. Furthermore, in this embodiment, the length of the ratchet 410 is greater than the distance between the fourth connector 420 and the tooth 3103 closest to the fourth connector 420 on the end face of the knob 310, so that the arc-shaped abutment portion 4101 on the ratchet 410 always abuts against the tooth 3103.

[0077] Furthermore, in this embodiment, a torsion spring 430 is fitted onto the fourth connecting member 420. One end of the torsion spring 430 is connected to the ratchet 410, and the other end of the torsion spring 430 is connected to the fourth connecting member 420. The torsion spring 430 is configured to limit the ratchet 410. A protrusion 4102 is provided on the lower end surface of the ratchet 410, and a limiting part 440 with an inclined surface 4401 is provided on the fourth connecting member 420. The limiting part 440 can limit the protrusion 4102.

[0078] For example, such as Figures 15-16As shown, when the user rotates the knob 310 in the drive unit (counterclockwise), the ratchet 410 rotates clockwise under the action of the teeth 3103. The protrusion 4102 and the limiting part 440 with the inclined surface 4401 prevent the ratchet 410 from rotating excessively. Specifically, the inclined surface 4401 on the limiting part 440 can limit the protrusion 4102, thus preventing the ratchet 410 from rotating excessively. Simultaneously, the torsion spring 430 further restricts the excessive rotation of the ratchet 410. The torsion spring 430 also applies a restoring force to the ratchet 410, i.e., a counterclockwise force, ensuring that the ratchet 410 and the teeth 3103 on the knob 310 always maintain a certain force, while also preventing the ratchet 410 from rotating excessively. In other words, during the rotation of the knob 310, the arc-shaped abutment portion 4101 at the end of the ratchet 410 can abut against the teeth 3103 of the knob 310 at all times. This prevents the knob 310 from rotating in the reverse direction, i.e., from rotating clockwise, thereby avoiding the problem of the driven member 340 automatically closing during use and improving the reliability and stability of the fixing device 300. Of course, operators can customize the relative rotation direction of the knob 310 and the ratchet 410 according to actual needs. The counterclockwise rotation direction of the knob 310 and the clockwise rotation direction of the ratchet 410 in this embodiment are only illustrative examples.

[0079] like Figure 9 As shown, in this embodiment, to improve the convenience of the user driving the knob 310, a screwing portion 3104 is provided on the end face of the knob 310. Optionally, the screwing portion 3104 is arranged in a straight line.

[0080] This embodiment also provides a vehicle, which mainly includes the aforementioned fixing device 300 and solar panel 100. The solar panel 100 is mounted on the vehicle via the fixing device 300. This vehicle can improve the efficiency of the solar panel 100 installation operation, thereby achieving the goal of cost saving.
