[0030] For clarity, in this invention, when the carriage is installed on a vehicle, the end where the front of the vehicle is located is called the front, and vice versa; the space closest to the carriage encloses is called the inner, and vice versa is called the outer.
[0031] like Figures 1 to 3 As shown, this utility model discloses a hinge structure, including a second hinge 711 and a third hinge 712 that are hinged together. The second hinge 711 is provided with a sixth insertion port 71124 with the opening tilted downwards and backwards. The upper end of the third hinge 712 is inserted into the sixth insertion port 71124 of the second hinge 711 and can rotate within the sixth insertion port 71124.
[0032] In this way, the sixth insertion port 71124 of the second hinge 711 can cover the upper end of the third hinge 712, ensuring that the hinge structure between the second hinge 711 and the third hinge 712 is not exposed, resulting in an aesthetically pleasing overall structure. It also prevents rainwater from entering between the second hinge 711 and the third hinge 712 from above, providing good sealing and waterproofing. The second hinge 711 and the third hinge 712 can be simply plugged together during assembly without the need for fasteners, making assembly simple and quick.
[0033] In this design, the first hinge 711 and the second hinge 712 are made of rubber material, which has high elasticity, long service life and good sealing effect.
[0034] like Figure 2 As shown, the sixth socket 71124 is composed of a first protrusion 71122 and a second protrusion 71123 located on the rear side of the second hinge 711. Inside the sixth socket 71124, from top to bottom, are arranged a first arc surface 711241, a stop surface 711242, and a second arc surface 711243. The extended surface of the stop surface 711242 can pass through the center of the first arc surface 711241.
[0035] like Figure 3 As shown, the upper end of the third hinge 712 is provided with a first arc-shaped portion 71241 and a second arc-shaped portion 71242. One end of the first arc-shaped portion 71241 is connected to the upper end of the third hinge 712, and the other end of the first arc-shaped portion 71241 is a free end. The center of the first arc-shaped portion 71241 coincides with the center of the first arc surface 711241, and the outer diameter of the first arc-shaped portion 71241 is adapted to the diameter of the first arc surface 711241. This allows the first arc-shaped portion 71241 to be placed inside the sixth insertion port 71124.
[0036] The second arc-shaped portion 71242 is disposed within the first arc-shaped portion 71241. The center of the second arc-shaped portion 71242 coincides with the center of the second arc surface 711243, and the outer diameter of the second arc-shaped portion 71242 is adapted to the diameter of the second arc surface 711243. This allows the second arc-shaped portion 71242 of the third hinge 712 to always rotate within the second arc surface 711243, thus eliminating the need for an independent pivot and enabling the second hinge 711 and the third hinge 712 to be hinged together.
[0037] A stop groove 71243 is provided between the lower part of the second arc-shaped portion 71242 and the first arc-shaped portion 71241;
[0038] The first arcuate portion 71241 of the third hinge 712 is disposed within the sixth insertion port 71124 of the second hinge 711. The first protrusion 71122 of the second hinge 711 is located within the stop groove 71243 of the third hinge 712. The second arcuate portion 71242 is located at the second arcuate surface 711243 of the sixth insertion port 71124 of the second hinge 711 and can rotate within the second arcuate surface 711243.
[0039] When the lift-up door 716 is opened, the free end of the first arc-shaped portion 71241 abuts against the stop surface 711242 within the sixth socket 71124, and the first protrusion 71122 of the second hinge 711 remains within the stop groove 71243 of the third hinge 712. When the lift-up door 716 is closed, the end of the first protrusion 71122 on the second hinge 711 away from the fourth connecting portion 7112 abuts against the bottom of the stop groove 71243 of the third hinge 712, and the free end of the first arc-shaped portion 71241 remains within the sixth socket 71124. This prevents the hinge connection between the third hinge 712 and the second hinge 711 from failing during rotation.
[0040] In this design, the second protrusion 71123 of the second hinge 711 can shield the third hinge 712, and the hinge structure of the second hinge 711 and the third hinge 712 is not exposed, resulting in an aesthetically pleasing overall structure. Furthermore, the second protrusion 71123 of the second hinge 711 can prevent rainwater and other substances from entering between the second hinge 711 and the third hinge 712.
[0041] When the third hinge 712 rotates relative to the second hinge 711, the second hinge 711 may undergo a certain deformation. Therefore, the front side of the fourth connecting part 7112 is provided with a recessed part 71121, so that the fourth connecting part 7112 can undergo appropriate deformation more easily.
[0042] The rotation angle between the second hinge 711 and the third hinge 712 can be set to 90° or more. Although the rotation angle range is large, the third hinge 712 will not fall out of the sixth socket 71124 of the second hinge 711.
[0043] The rear end of the third connecting part 7111 extends rearward to form a second eaves 71111, thereby further blocking rainwater.
[0044] To facilitate the connection of the second hinge 711 to components such as the plate, the second hinge 711 includes a third connecting portion 7111, a fourth connecting portion 7112, and a fifth connecting portion 7113. The third connecting portion 7111 and the fifth connecting portion 7113 are horizontally arranged, and the upper end of the fourth connecting portion 7112 is vertically connected to the third connecting portion 7111. The lower end of the fourth connecting portion 7112 is vertically connected to the rear side of the fifth connecting portion 7113, thereby forming a U-shaped groove between the third connecting portion 7111, the fourth connecting portion 7112, and the fifth connecting portion 7113. The plate is disposed within this U-shaped groove. The rear side of the fourth connecting portion 7112 has a first protrusion 71122 and a second protrusion 71123. A sixth insertion port 71124 with an opening that slopes downwards and backwards is formed between the first protrusion 71122 and the second protrusion 71123.
[0045] To facilitate the connection of the third hinge 712 to components such as the plate, the third hinge 712 includes a sixth connecting part 7121, a seventh connecting part 7122, an eighth connecting part 7123, and a ninth connecting part 7124. The sixth connecting part 7121 and the eighth connecting part 7123 are vertically arranged. The upper ends of the sixth connecting part 7121 and the eighth connecting part 7123 are respectively connected to the front and rear sides of the seventh connecting part 7122, thereby forming a U-shaped groove between the sixth connecting part 7121, the seventh connecting part 7122, and the eighth connecting part 7123. The lower end of the ninth connecting part 7124 is connected to the seventh connecting part 7122, and the upper end of the ninth connecting part 7124 is provided with a first arc-shaped part 71241 and a second arc-shaped part 71242.
[0046] On the third hinge 712, a water guide channel is formed between the ninth connecting part 7124 and the seventh connecting part 7122. The seventh connecting part 7122 is arranged to be inclined downward from front to back, so as to facilitate the drainage of water in the water guide channel.
