Description

Technical Field

[0001] The utility model belongs to the technical field of automobile spare tire racks, and particularly relates to an automobile spare tire rack. Background Technique

[0002] As an important part of modern life, automobiles not only provide great convenience for people's daily travel, but also become an important symbol to measure a country's industrial level. With the continuous development of the automobile industry, aspects such as the safety, comfort and durability of vehicles have also been increasingly emphasized. Among them, as an important part of the automobile, the design and manufacturing technology of the spare tire rack is also constantly progressing to meet higher usage requirements and safety standards.

[0003] The spare tire rack is a device on the automobile for storing the spare tire. It not only needs to have sufficient load-bearing capacity to ensure the stability of the spare tire during vehicle driving, but also needs to facilitate the driver to quickly replace the tire in case of an emergency. Therefore, the design of the spare tire rack should not only consider the stability and durability of its structure, but also consider the convenience and safety of its operation. In view of this, we propose an automobile spare tire rack. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automobile spare tire rack to solve the problems raised in the above background technique.

[0005] In view of this, the utility model provides an automobile spare tire rack, including:

[0006] A rear surround lower bracket, on which a spare tire rack main body is rotatably installed. At the top end of the spare tire rack main body, a rear surround upper bracket is rotatably installed. On one side of the spare tire rack main body, a spare tire support plate is fixedly installed. On one side of the spare tire support plate, four hollow circular tubes are fixedly installed. On the circumferential side of the hollow circular tubes, a spare tire mounting seat is fixedly installed. On one side of the spare tire support plate, a spare tire support rod is fixedly installed.

[0007] A fixing component, which is located on the spare tire support plate and is used to fix the spare tire on the four hollow circular tubes;

[0008] A second bolt, which is fixedly installed on the other side of the spare tire rack main body. A rubber limit block and a gasket are sleeved on the second bolt, and the gasket is located inside the rubber limit block. At one end of the second bolt, a second nut is threadedly installed. On one side of the spare tire rack main body and away from the rear surround lower bracket, a handrail is fixedly installed. On the spare tire rack main body and on one side of the handrail, a sliding rod is fixedly installed.

[0009] A sliding mechanism, which is located on the sliding rod and is used to slide on the sliding rod.

[0010] In this technical solution, at this time, the user can put the spare tire on the four hollow tubes and fix the spare tire through the fixing component, so as to fix the spare tire on the four hollow tubes. When the user needs to use the spare tire, the fixing component can release the fixation of the spare tire, and then the spare tire can be removed from the spare tire support plate. The operation is simple and fast, ensuring that it is convenient for the user to remove and replace the spare tire;

[0011] Through the provided sliding mechanism, the sliding mechanism can ensure the structural stability when the rear door is opened. When the rear door is closed, the rubber limit block can buffer the main body of the spare tire rack, preventing the main body of the spare tire rack from hitting the vehicle body when closing, thus causing damage to the vehicle body. However, when the rubber limit block is hit for a long time, the rubber limit block will be damaged. At this time, the user can use an Allen wrench to rotate nut two. Under the action of the thread, nut two can be removed from bolt two, and then the gasket is removed. At this time, nut two and the gasket can release the limit on the rubber limit block. The user can remove the damaged rubber limit block and replace it, then put the gasket and nut two on bolt two and tighten nut two, so as to replace the rubber limit block, ensuring that the rubber limit block can buffer the main body of the spare tire rack and preventing the main body of the spare tire rack from damaging the vehicle body when closing. At the same time, it is also convenient for the user to replace the rubber limit block when it is damaged.

[0012] In the above technical solution, further, the fixing component includes:

[0013] Four bolts one, and the four bolts one are all fixedly installed on the other side of the spare tire support plate. One end of the bolt one penetrates through the spare tire support plate and the corresponding hollow tube and is threadedly installed with nut one.

[0014] In this technical solution, the spare tire support plate is welded to one side of the main body of the spare tire rack. At this time, the user can put the spare tire on the four hollow tubes and fix the spare tire through four nuts one, so as to fix the spare tire on the four hollow tubes. When the user needs to use the spare tire, only need to unscrew the four nuts one to remove the spare tire from the spare tire support plate. The operation is simple and fast, ensuring that it is convenient for the user to remove and replace the spare tire.

[0015] In the above technical solution, further, one side of nut one abuts against one end of the hollow tube.

[0016] In this technical solution, it is ensured that nut one can limit the hollow tube.

[0017] In the above technical solution, further, the sliding mechanism includes:

[0018] A rubber ring is sleeved on a sliding rod. A sliding shaft is fixedly installed on the circumferential side of the rubber ring. Sleeve fixing seats are rotatably installed at the top and bottom ends of the sliding shaft. A same rectangular seat is fixedly installed between the two sleeve fixing seats and on one side of the sliding shaft. Reinforcing plates are fixedly installed on the sides of the two sleeve fixing seats away from each other. Bolts III are symmetrically installed on the reinforcing plates in a threaded manner. One end of each bolt III penetrates through the reinforcing plate and the sleeve fixing seat. A long bolt is installed on one of the reinforcing plates and on the other side of the sliding shaft in a threaded manner. The bottom end of the long bolt penetrates through the two reinforcing plates and the two sleeve fixing seats and is threadedly installed with a nut III. A long circular tube is sleeved on the long bolt between the two sleeve fixing seats.

[0019] In this technical solution, one side of the rectangular seat is fixed to the rear door of the vehicle by bolts and nuts. When a person needs to open the rear door, the armrest can be pulled. The armrest will drive the spare tire rack main body to rotate, so that the spare tire rack main body rotates between the lower rear enclosure bracket and the upper rear enclosure bracket, and will also drive the rear door to open through the sliding rod and the rectangular seat. At the same time, the sliding shaft and the rubber ring will slide on the sliding rod, and the sliding shaft will rotate between the two sleeve fixing seats to ensure the structural stability when the rear door is opened.

[0020] In the above technical solution, further, the sliding rod is slidably connected to the rubber ring, the rubber ring is tightly bonded to the inner wall of the sliding shaft, the bolt III is threadedly connected to the reinforcing plate and the sleeve fixing seat, and the long bolt is threadedly connected to the reinforcing plate and the sleeve fixing seat.

[0021] In this technical solution, it is ensured that the rubber ring can slide normally on the sliding rod, the structures of the rubber ring and the sliding shaft are stable, and the four bolts III and the long bolt can fix the two reinforcing plates on the two sleeve fixing seats.

[0022] In the above technical solution, further, the spare tire mounting seat is snap-fitted with the spare tire support plate, and the gasket is located between the rubber limit block and the nut II.

[0023] In this technical solution, it is ensured that the mounting seat can be stuck on the support plate and the structure of the gasket is stable.

[0024] In the above technical solution, further, the spare tire support plate is tightly welded to the spare tire rack main body.

[0025] In this technical solution, it is ensured that the structures of the spare tire support plate and the spare tire rack main body are stable.
