Description

Technical Field

[0001] The utility model relates to the technical field of vehicle spare tire installation, in particular to a flip spare tire rack. Background Art

[0002] A semi-trailer is a trailer with the axle placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. Semi-trailers are generally three-axle semi-trailers, which are divided into many types such as 11-meter warehouse semi-trailers, 13-meter warehouse semi-trailers, low-bed semi-trailers, etc. It is a heavy-duty transportation vehicle connected to the semi-trailer head through a traction pin.

[0003] The design of the semi-trailer also includes a spare tire rack. The patent with the rack announcement number CN212195671U discloses a flip spare tire rack, including a cylinder, a rotating connecting rod, a V-shaped lifting rod, and a spare tire fixing frame. The cylinder is in an inclined state, and the V-shaped lifting rod moves toward or away from the upper fixing frame under the push and pull of the cylinder. At the same time, the rotating connecting rod rotates relative to the upper fixing frame and the V-shaped lifting rod.

[0004] The current flip spare tire rack uses a cylinder to drive the rotating connecting rod and other structures to drive the spare tire to rotate. However, this method has a higher requirement on the cylinder diameter. The larger the cylinder diameter, the easier it is to interfere with the spare tire. The smaller the cylinder diameter, the greater the required air pressure, which makes the cylinder prone to explosion and the spare tire rack structure unstable. Utility Model Content

[0005] In view of the above problems, the utility model provides a flip spare tire rack.

[0006] In order to achieve the above-mentioned invention object, the technical solution adopted by the utility model is as follows:

DETAILED DESCRIPTION

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] The present application embodiment discloses a flip spare tire rack, referring to Figure 1 , Figure 2 and Figure 3 , including a mounting base 1, the cross section of the mounting base 1 is "L" shaped, one end of the mounting base 1 is horizontal and the other end is vertically downward when in use. A driving cylinder 6 is hinged at the end of the horizontal section of the mounting base 1, and two groups of driving cylinders 6 are arranged at intervals along the width direction of the mounting base 1, and are arranged near the edges of both sides of the mounting base 1. A rotating connecting rod 4 is hinged on the vertical section of the mounting base 1, and the end of the rotating connecting rod 4 away from the mounting base 1 is connected to a first connecting pipe 5 along the width direction of the mounting base 1, and the rotating connecting rod 4 is connected to the middle of the first connecting pipe 5. The piston rod ends of the two driving cylinders 6 are respectively rotatably connected to the two ends of the first connecting tube 5, and the first connecting tube 5 is rotatably connected with a V-shaped rod 7. The mounting seat 1 is hinged with a first H-shaped rod 8 below the rotating connecting rod 4. The V-shaped rod 7 and the first H-shaped rod 8 are hinged to each other so that the V-shaped rod 7, the first H-shaped rod 8, the rotating connecting rod 4 and the mounting seat 1 form a quadrilateral hinge structure. The end of the first H-shaped rod 8 away from the mounting seat 1 is hinged with a second H-shaped rod 10, and also includes a fixing plate 11 for the spare tire 12 to be connected. The end of the V-shaped rod 7 away from the first connecting tube 5 and the end of the second H-shaped rod 10 away from the first H-shaped rod 8 are both hinged on the fixing plate 11. Specifically, the hinge point of the V-shaped rod 7 and the first H-shaped rod 8 is located at a point between the hinge axes of the two ends of the two rods.

[0021] The first H-rod 8 and the second H-rod 10 are both made of two parallel plates with connecting ribs between the plates, so that the H-rod has a good load-bearing capacity. When the piston rod of the driving cylinder 6 is extended, the rotating connecting rod 4 and the end of the first H-rod 8 away from the mounting seat 1 are pushed to rotate downward, and the V-rod 7 is moved downward. Then, the V-rod 7 and the second H-rod 10 work together to rotate the fixed plate 11 from a horizontal state to a vertical state, and the spare tire 12 on the fixed plate 11 is turned out from under the vehicle. Under the premise of satisfying the power for turning the spare tire 12, the two driving cylinders 6 can be staggered with the apex of the spare tire 12 in the vertical state to avoid interference between the driving cylinders 6 and the spare tire 12.

[0022] Reference Figure 2 and Figure 3Furthermore, two groups of the first H-rod 8 and the second H-rod 10 are arranged in parallel, the two first H-rods 8 and the two second H-rods 10 correspond to each other and are hinged to each other, and the V-rod 7 and the two first H-rods 8 are connected to each other by relative rotation through the second connecting tube 9. The carrying capacity of the spare tire rack can be improved by providing two groups of the first H-rod 8 and the second H-rod 10. In the embodiment of the present application, the second H-rod 10 is arc-shaped, wherein the arc-shaped convex surface of the second H-rod 10 faces the fixing plate 11, so that the second H-rod 10 has a higher carrying capacity during the flipping of the spare tire 12.

[0023] In the embodiment of the present application, both sides of the mounting seat 1 are fixedly mounted with reinforcing ribs 2, the reinforcing ribs 2 are triangular pieces of supporting legs, and the two sides of the reinforcing ribs 2 are respectively fixedly connected to the two sides of the mounting seat 1, so as to increase the structural strength of the mounting seat 1 through the reinforcing ribs 2. Furthermore, a plurality of perforations are hollowed out on the reinforcing ribs 2 to reduce the overall mass of the mounting seat 1.

[0024] Furthermore, a first locking hole is opened on the two reinforcing ribs 2, and second locking holes are coaxially opened at both ends of the first connecting tube 5. When the piston rod of the driving cylinder 6 is retracted and the fixing plate 11 is lifted to a horizontal state, the second locking hole on the first connecting tube 5 is aligned with the first locking hole on the reinforcing rib 2. At this time, the locking shaft 3 is inserted from the first locking hole of the reinforcing rib 2. The locking shaft 3 is simultaneously inserted into the first locking hole and the second locking hole, which can limit the movement of the first connecting tube 5. During normal driving, the locking shaft 3 can be inserted from the side of the mounting seat 1 to keep the fixing plate 11 in a horizontal state. When the spare tire 12 needs to be taken out, the locking shaft 3 is taken out to improve the stability of the spare tire rack in the storage state.

[0025] Reference Figure 4 Furthermore, a first connection seat 13 is hingedly connected to one end of the V-shaped rod 7 close to the fixing plate 11, and the first connection seat 13 is connected and fixed to the fixing plate 11 by bolts. A second connection seat 14 is hingedly connected to one end of the second H-shaped rod 10 away from the first H-shaped rod 8, and a strip hole 15 is provided on the second connection seat 14. The bolts on the second connection seat 14 pass through the fixing plate 11 after passing through the strip hole 15, thereby connecting the fixing plate 11 with the second connection seat 14. Through the design of the strip hole 15, when installing spare tires 12 of different sizes using fixing plates 11 of different sizes, when the first connection seat 13 is fixed in position, the bolts on the second connection seat 14 can be adapted to align with the connection through holes on the fixing plates 11 of different sizes through the strip hole 15.
