Detailed Implementation

[0022] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0023] like Figures 1 to 5 As shown, a through passage includes a canopy structure 100, which includes a suspension assembly 10 fixedly installed on a top folding canopy, a bending assembly 20 fixedly installed on the suspension assembly 10, and a canopy assembly 30 fixedly installed on the bending assembly 20.

[0024] The suspension assembly 10 includes several vertical rods 110 fixed to the top folding canopy and horizontal rods 120 fixed to the vertical rods 110. One end of each vertical rod 110 is fixed to the top folding canopy, and the other end of each vertical rod 110 points vertically downwards. Horizontal rods 120 are vertically mounted on the other end of each vertical rod 110. There are multiple horizontal rods 120 and multiple vertical rods 110, which, together with the top folding canopy, form a quadrilateral. The connection between the vertical rods 110 and the horizontal rods 120 provides an installation position for the bending assembly 20 and the canopy panel assembly 30, allowing the canopy panel assembly 30 to be fixed to the canopy fabric.

[0025] The bending assembly 20 includes a connecting plate 210 fixed to the crossbar 120 and a hinge 220 fixed to the connecting plate 210. There are two connecting plates 210, one of which has a bent structure. The connecting plate 210 is fixed to the crossbar 120, and its bottom is bent and extends above the canopy assembly 30. One side of the hinge 220 is fixed to the connecting plate 210, and the other side is fixed to the canopy assembly 30. When the vehicle body passes over bumpy or winding road sections, the connecting plate 210, in conjunction with the hinge 220, deforms to counteract stress from the road and assist the vehicle body in navigating such road sections.

[0026] The shelf assembly 30 includes a double shelf 310, a single shelf 320, and a pin 330. The double shelf 310 includes an upper pressure plate 311 and a lower bottom plate 312. Both the pressure plate 311 and the bottom plate 312 have a bent structure. The ends of the pressure plate 311 and the bottom plate 312 are fixed to the hinge 220. The bending angle of the pressure plate 311 is 'a', and the bending angle of the bottom plate 312 is 'b'. The value of 'a' is 1° to 3° greater than that of 'b'. The pressure plate 311 is set at... Inside the bend of the base plate 312, the bending direction of the pressure plate 311 is the same as that of the base plate 312. At the ends of the bend away from the bend, the double-shelf plate 310 and the single-shelf plate 320 interlock. Specifically, a cavity is formed between the pressure plate 311 and the base plate 312, and the single-shelf plate 320 extends into this cavity. Under the influence of gravity, the single-shelf plate 310 presses against the base plate 312, and the pressure plate 311 presses against the single-shelf plate 310. The interlocking single-shelf plate 320 and the double-shelf plate 310 together form a planar structure, shielding the outer folded structure. A groove 313 is provided in the middle of the pressure plate 311, and the pin 330 is movably accommodated in the groove 313. Under the restraining effect of the groove 313 on the pin 330, the movement range of the single-shelf plate 320 relative to the double-shelf plate 310 is limited.

[0027] Preferably, a limiting screw 317 is inserted through the pressure plate 311, and a nut is fitted on the limiting screw 317. The limiting screw 316 is located near the bend. The nut portion of the limiting screw 317 is between the pressure plate 311 and the base plate 312. Under the clamping of the nut and the nut, the limiting screw 317 is fixed on the pressure plate 311. The nut portion blocks and restricts the cavity between the pressure plate 311 and the base plate 312, ensuring the existence of the cavity for receiving the single shelf plate 310.

[0028] Preferably, the value of a is 2° greater than that of b. Since the bending angle of the pressure plate 311 is large and the bending angle of the bottom plate 312 is small, and one side of the pressure plate 311 and the bottom plate 312 are fixed together, the other side of the pressure plate 311 and the bottom plate 312 abut against each other to clamp the single shelf 320 due to the bending angle.

[0029] Preferably, the value of 'a' is between 75° and 82°, and the bending angle of the single shelf panel 320 and the bending angle of the base plate 312 are the same. This type of angle distribution avoids mismatch between the bending angle of the single shelf panel 320, the bending angle of the pressure plate 311, and the bending angle of the base plate 312. The single shelf panel 320 can be inserted precisely between the base plate 312 and the pressure plate 311.

[0030] Preferably, the end of the single shelf 320 pressed on the pressure plate 311 is provided with a rolled edge portion 323, and the end of the single shelf 320 can be smoothly guided by the rolled edge portion 323 to be inserted between the pressure plate 311 and the bottom plate 312.

[0031] Preferably, the bottom plate 312 has a ramp 314 at the end facing the single shelf 320. The ramp 314 is positioned facing the single shelf 320. When the single shelf 320 extends between the pressure plate 311 and the bottom plate 312, the end of the single shelf 320 can be smoothly guided by the ramp 314, reducing the probability of impact.

[0032] Preferably, a flange 315 is provided on the edge of the groove 313. The flange 315 is formed by folding the pressure plate 311 upward along the shape of the groove 313. The flange 315 plays a role in protecting the pin 330, increasing the area when the pin 330 hits the edge of the groove 313, and reducing the degree of impact deformation.

[0033] Preferably, a baffle 316 is provided around the outer side of the flange portion 315. The baffle 316 is fixed on the flange portion 315. The baffle 316 is used to reduce the gap of the flange portion 315, so that the flange portion 315 forms an integral structure around the slide groove 313, thereby improving the strength of the flange portion 315.

[0034] Preferably, the end of the single shelf 320 is wrapped with a wear-resistant pad 321, which contacts the bottom plate 312 and the pressure plate 311. Through the substitution friction of the wear-resistant pad 321, the wear of the pressure plate 311, the bottom plate 312 and the single shelf 320 can be reduced.

[0035] When the aforementioned through passage is in use, the suspension assembly 10 in the shelf structure 100 is fixed to the folding shelf, the connecting plate 210 is fixed on the suspension assembly 10, and the hinge 220 is fixed on the connecting plate 210. When the folding shelf expands or contracts, under the connection of the suspension assembly 10, the connecting plate 210 drives the hinge 220 to move along with the expansion and contraction of the folding shelf. The other side of the hinge 220 is connected to a single shelf 320 and a double shelf 310 respectively. The single shelf 320 is inserted into the double shelf 310. When the single shelf 320 slides between the double shelf 310, the pin 330 on the single shelf 320 slides synchronously in the slide groove 313. Due to the restriction of the pin 330 by the groove wall of the slide groove 313, the lateral movement of the single shelf 320 is prevented from exceeding the travel limit. Since the bending angle a of the pressure plate 311 is 1° to 3° larger than the bending angle b of the base plate 312, the bending angle of the pressure plate 311 is within the bending angle of the base plate 312, and the two bending angles coincide with each other. Therefore, the ends of the pressure plate 311 and the base plate 312 are close to each other and jointly clamp the single shelf plate 320. Due to the difference in bending angles and the limitation of the nuts of the limiting screws 317, the pressure plate 311 and the base plate 312 accommodate and clamp the single shelf plate 320.

[0036] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
