This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.
[0005] To address the technical problems mentioned in the background section above, some embodiments of this application provide a connection structure for a roof panel, wherein a trapezoidal protrusion and a locking portion located above the trapezoidal protrusion are formed on the roof panel; the connection structure includes: a first clamping plate, a second clamping plate, and a locking member; the first clamping plate forms a first abutting surface that abuts against the trapezoidal protrusion and a first locking surface that abuts against the locking portion; the second clamping plate forms a second abutting surface that abuts against the trapezoidal protrusion and a second locking surface that abuts against the locking portion; the cross-sectional area of the middle portion of the locking portion is larger than the cross-sectional area of the lower portion of the locking portion.

[0027] A connection structure for a roof panel, wherein a trapezoidal protrusion 1 and a locking portion located above the trapezoidal protrusion 1 are formed on the roof panel. The connection structure includes: a first clamping plate 2, a second clamping plate 3, and a locking member 4. The locking member 4 is a double-ended stud or bolt, and passes through the first clamping plate 2 and the second clamping plate 3. The first clamping plate 2 has a first abutting surface 21 that abuts against the trapezoidal protrusion 1 and a first locking surface 22 that abuts against the locking portion. The second clamping plate 3 has a second abutting surface 31 that abuts against the trapezoidal protrusion 1 and a second locking surface 32 that abuts against the locking portion; the middle cross-sectional area of the locking portion is larger than the lower cross-sectional area of the locking portion. By adopting the above technical solution, since the cross-sectional area of the middle part of the card part is larger than the cross-sectional area of the lower part of the card part, when both the first card surface 22 and the second card surface 32 abut against the card part, the first card surface 22 and the second card surface 32 can clamp the card part tightly, thereby fixing the first clamping plate 2 and the second clamping plate 3 to the card part, and further fixing the first clamping plate 2 and the second clamping plate 3 to the roof panel. The first clamping plate 2 and the second clamping plate 3 receive the connecting object, thus making it relatively easy to install the object to be connected on the roof panel.
[0028] Specifically, the trapezoidal protrusion 1 has a first side surface and a second side surface; the first abutting surface 21 abuts against the first side surface, and the second abutting surface 31 abuts against the second side surface. By utilizing the abutting surface 21 against the first side surface and the abutting surface 31 against the second side surface, the first clamping plate 2 and the second clamping plate 3 can extend to the side surface of the trapezoidal protrusion 1, thereby increasing the length of the first clamping plate 2 and the second clamping plate 3. This allows the first clamping plate 2 and the second clamping plate 3 to provide more support to prevent the object to be connected from tipping over, making the connection more secure.
[0029] Specifically, the trapezoidal protrusion 1 forms a top surface that connects with the first side and the second side; both the first abutting surface 21 and the second abutting surface 31 abut against the top surface. This allows the first clamping plate 2 and the second clamping plate 3 to provide even more support to prevent the object to be connected from tipping over.
[0030] Specifically, a limiting part 5 is formed between the first clamping plate 2 and the second clamping plate 3; when the first clamping plate 2 and the second clamping plate 3 clamp the card part, a receiving groove is formed between the first clamping plate 2 and the second clamping plate 3, and the limiting part 5 is disposed in the receiving groove; the limiting part 5 is used to abut against the first clamping plate 2 and the second clamping plate 3. The locking structure is used to apply a mutual tightening force to the first clamping plate 2 and the second clamping plate 3 on the side of the first clamping plate 2 away from the receiving groove and on the side of the second clamping plate 3 away from the receiving groove. The locking member 4 is located below the limiting part 5. The limiting part 5 is for abutting against the first clamping plate 2 and the second clamping plate 3 and preventing the first clamping plate 2 and the second clamping plate 3 from bending significantly when locked by the locking member 4, thereby better ensuring the shape of the first clamping plate 2 and the second clamping plate 3, thus making the first clamping plate 2 and the second clamping plate 3 more stable.
[0031] Specifically, the limiting part 5 is fixed to the first clamping plate 2; the second clamping plate 3 is provided with a mounting part 6, which is located above the limiting part 5 and abuts against it; the mounting part 6 is used to mount the object to be connected. The mounting part 6 extends partially to the outside of the first clamping plate 2 and the second clamping plate 3. The way the limiting part 5 supports the mounting part 6 allows the object to be connected mounted on the mounting part 6 to be better supported by the first clamping plate 2 and the second clamping plate 3, preventing the mounting part 6 from bending and ensuring better connection stability. Both the limiting part 5 and the mounting part 6 are plate bodies.
[0032] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
