[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-5A device for fixing a spare tire on the backrest of a rear seat of a car comprises a rear seat back plate 1 of the car and a spare tire. The rear seat back plate 1 of the car is fixedly installed on the back of the last row of seats in the car (the seats are not shown in the figure). A plurality of second limiting plates 9 are connected to the bottom of the front of the rear seat back plate 1 of the car. A plurality of slide grooves are opened on the upper front of the rear seat back plate 1 of the car, and a sliding column is arranged in the groove. A sliding block 2 is connected to the outer end of the sliding column. A moving plate 3 is connected to the side of the sliding block 2 away from the rear seat back plate 1 of the car. The moving plate 3 is used to adjust the sliding of the sliding block 2 in the slide groove. A plurality of slide grooves are opened on the surface of the rear seat back plate 1 of the car along the upper and lower surfaces of the slide groove. A threaded hole, a connecting screw 4 with a corresponding threaded hole is connected to the side of the movable plate 3 away from the rear seat back plate 1 of the automobile, a first limiting plate 6 is movably connected to the side of the movable plate 3 away from the rear seat back plate 1 of the automobile, a first strap 7 is connected to the end of the first limiting plate 6, a first strap 7 is connected to one side of the end of the first triangular ring 8, a ratchet tightener 12 is connected to the bottom edge of the first triangular ring 8, and a second triangular ring 11 is connected to the other end of the ratchet tightener 12, a second strap 10 is connected to the top of the second limiting plate 9, and the second straps 10 are all connected to the second triangular ring 11, and a tire pressure monitoring structure is arranged at the air core of the spare tire corresponding to the front of the rear seat back plate 1 of the automobile.

[0032] Furthermore, a hanging ring 5 is provided at the middle end of the movable plate 3 away from the rear seat back plate 1 of the automobile, and a hook 601 is connected to the outer end of the hanging ring 5, and the hook 601 is connected to the end of the first limiting plate 6.

[0033] The advantage is that when installing the spare tire, the spare tire is placed on the top of the two second limiting plates 9, and the hook 601 is hung on the hanging ring 5 to complete the preliminary limiting of the spare tire.

[0034] Furthermore, there are two slide grooves, and each slide groove is provided with the same sliding block 2. The two slide grooves can ensure that the two hooks 601 are provided to apply pressure to the spare tire from both sides. The central axis of the inner ring of the hanging ring 5 is vertically downward, and the surface is smooth. The hook 601 is hung in the hanging ring 5, and the hook 601 is rotatably connected to the middle part of the end of the first limiting plate 6. Due to the inconsistent spare tire sizes of different models or the inconsistent types of spare tires, such as full-size spare tires or half-size spare tires, when the size of the spare tire is too large, the fixed hanging structure will cause the hook 601 to be unable to be hung. At this time, the sliding block 2 is used to drive the movement of the movable plate 3, and the hanging ring 5 is driven to move to adapt to the installation of spare tires of various sizes.

[0035] Furthermore, a movable plate 3 is fixedly installed on one side of the sliding block 2 away from the rear seat back panel 1 of the automobile, and a connecting screw 4 is slidingly connected between the movable plate 3 and the rear seat back panel 1 of the automobile. After adjusting the position of the movable plate 3, the connecting screw 4 is inserted into the corresponding threaded hole, and the connecting screw 4 is threadedly connected with the corresponding threaded hole, thereby fixing the position of the connecting plate 3.

[0036] Furthermore, the connecting screws 4 are used to connect and fasten the movable plate 3 and the threaded holes on the rear seat back plate 1 of the automobile after the movable plate 3 slides. After the spare tire is used, if the spare tire needs to be replaced and if the type of the replaced spare tire is inconsistent, such as a full-size spare tire or a half-size spare tire, the connecting screws 4 can be loosened and the position of the hanging ring 5 can be readjusted.

[0037] Furthermore, the first triangular ring 8 and the second triangular ring 11 are both isosceles triangles, the outer ends of the first triangular ring 8 at both waists are fixed to the first binding strap 7, the outer ends of the second triangular ring 11 at both waists are fixed to the second binding strap 10, the second triangular ring 11 is connected to the fixed binding column of the ratchet tightener 12, the first triangular ring 8 is connected to the binding column used for winding up the ratchet tightener 12, and the first triangular ring 8 is pulled downward by the ratchet tightener 12, and the ratchet tightener 12 winds up the binding column, thereby driving the first binding strap 7 to tighten downward to complete the fixation of the spare tire. At the same time, due to the shortening of the distance, the first binding strap 7 and the second binding strap 10 will apply a force toward the rear seat back plate 1 of the car to the spare tire after being attached, so that the friction between the spare tire and the rear seat back plate 1 of the car is increased, so that it will not fall.

[0038] Furthermore, a pad 602 made of elastic material is fixedly installed on the contact surface of the first limit plate 6 with the spare tire, and a pad 601 is arranged on the contact surface of the first limit plate 6 with the spare tire. When the ratchet tightener 12 pulls the first triangular ring 8 downward and the ratchet tightener 12 reels the binding column, the pad 601 is in full contact with the surface of the spare tire. Since the pad 601 is made of elastic material, the friction coefficient of the pad 601 surface is relatively high, thereby avoiding left and right shaking during driving of the vehicle.

[0039] Furthermore, the tire pressure monitoring structure includes an air core connecting nozzle 13, a connecting tube 14 and a tire pressure detection device 15. The air core connecting nozzle 13 is connected to the air core of the spare tire, and the connection point is sealed. The connecting tube 14 is a corrugated tube, which is used to connect the internal gas of the spare tire to the tire pressure detection device 15. After replacing the spare tire, the length of the connecting tube 14 can be adjusted according to different spare tire sizes.

[0040] Furthermore, the tire pressure detection device 15 detects the tire pressure through the gas received by the connecting tube 14, and sends the detected tire pressure to the vehicle driver. The tire pressure monitoring device 15 integrates a tire pressure meter and a Bluetooth module. The Bluetooth module is connected to the vehicle driving central control by Bluetooth, and the tire pressure monitoring data is sent to the vehicle driving central control. This behavior is only displayed on the central control when the vehicle is started, so as to inform the owner of the spare tire status in time and avoid the occurrence of spare tire abnormality during driving.

[0041] During use, when the spare tire needs to be replaced, it is only necessary to unlock the ratchet tightener 12 and remove the hook 601 from the hanging ring 5 to complete the removal of the spare tire and then install the spare tire. When installing a new spare tire, the sliding block 2 can be used to drive the movement of the movable plate 3, and the hanging ring 5 can be driven to move to adapt to the installation of spare tires of various sizes. Then, the ratchet tightener 12 is tightened, the first triangular ring 8 is pulled downward, and the ratchet tightener 12 reels the binding column to reel in, thereby driving the first strap 7 to tighten downward to complete the fixation of the spare tire. At the same time, due to the shortening of the distance, the first strap 7 and the second strap 10 will apply a force toward the rear seat back plate 1 of the car to the spare tire after being attached, so that the friction between the spare tire and the rear seat back plate 1 of the car is increased, so that it will not slip.

[0042] Among them, four sliding blocks 2 can be detachably arranged on the front side of the rear seat back plate 1 of the automobile, and each sliding block 2 is provided with a hanging ring 5. The ends of the first limiting plate 6 and the second limiting plate 9 can be hung by installing a hook 601, so that they can be removed when the tire is not installed.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
