Description

Technical Field

[0001] The utility model relates to the technical field of motor vehicles, in particular to a telescopic spare tire rack. Background Art

[0002] A spare tire rack is a special support structure installed inside or outside a car to fix and carry spare tires. The location and form of spare tire racks vary depending on the model and design. Traditional spare tire racks are commonly found inside the trunk of a car. They are a metal frame structure used to stably hang the spare tire on the vehicle chassis or under the trunk floor. Off-road vehicles are vehicles specially designed to travel in complex and harsh terrain conditions, with good passability and off-road performance. They are usually equipped with powerful four-wheel drive systems, high ground clearance, large approach and departure angles, and special suspension systems to cope with various extreme road conditions such as rugged mountain roads, muddy wetlands, and deserts. Spare tire racks for off-road vehicles often adopt a more durable design due to their special uses and environments. For example, the spare tire may be installed on the outside of the rear of the vehicle, using an open metal frame as the spare tire rack, which is convenient for access and avoids the space limitations and difficulty of access caused by internal storage in complex terrain. At the same time, the externally mounted spare tire can also play a certain protective role, such as preventing the tail from being damaged by minor collisions in the wild environment. At the same time, the tires of off-road vehicles are different from those of ordinary cars. The tires of ordinary cars generally have the same size, while the width and performance of off-road vehicle tires can be selected according to the environment, which leads to different widths and sizes of spare tires. The general spare tire rack is a fixed structure and cannot accommodate spare tires of different widths. In addition, the reversing image lens equipped with off-road vehicles is generally set in the center of the spare tire rack. After replacing a wider spare tire, it is easily blocked by the spare tire and cannot be used. Utility Model Content

[0003] Technical problems to be solved by utility models

[0004] In view of the technical problems that the existing spare tire rack cannot adapt to spare tires of different widths and the reversing image lens equipped for an off-road vehicle is easily blocked by the spare tire after a wider spare tire is replaced, making it unusable, the utility model provides a telescopic spare tire rack that can load spare tires of different widths and enables the reversing image to be used even after a wider spare tire is replaced.

[0005] Technical Solution

[0006] In order to solve the above problems, the technical solution provided by the utility model is:

[0007] A telescopic spare tire rack comprises a connecting seat connected to a vehicle body; a telescopic sleeve 1 connected to the connecting seat; a telescopic sleeve 2 slidably connected to the telescopic sleeve 1; an adjustment structure for fixing or adjusting the relative position of the telescopic sleeve 1 and the telescopic sleeve 2; and a spare tire fixing seat for connecting a spare tire and fixedly connected to the telescopic sleeve 2.

[0008] The connecting seat is used to connect the spare tire rack and the vehicle body. The main function of the connecting seat is to firmly and stably connect to the main structure of the car, that is, the vehicle body, forming the key link of the basic support and torque transmission between the spare tire rack and the vehicle body. On the basis of the connecting seat, a telescopic sleeve 1 is further provided as a key component, which is closely connected to the connecting seat and realizes effective linkage with the connecting seat through precise design. The core function of the telescopic sleeve 1 is to provide a preliminary length adjustment space for the spare tire rack. Furthermore, the telescopic sleeve 2, as a slidably connected component, is sleeved on the outside of the telescopic sleeve 1 to form a telescopic system. Through the sliding telescopic method, the telescopic sleeve 2 can be smoothly and accurately adjusted relative to the telescopic sleeve 1 according to actual needs to adapt to the loading requirements of spare tires of different widths. The telescopic sleeve 1 and the telescopic sleeve 2 are combined and slidably telescoped to adjust the distance between the spare tire fixing seat and the connecting seat, so as to adapt to the loading of spare tires of different widths; at the same time, in order to ensure that the spare tire rack can maintain a stable state after being adjusted to an appropriate width, an adjustment structure is specially equipped. The adjustment structure can lock and fine-tune the relative position of the telescopic sleeve 1 and the telescopic sleeve 2. The adjustment structure is used to adjust the relative positions of the telescopic sleeve 1 and the telescopic sleeve 2, so that the telescopic sleeve 2 can be fixed after adapting to the width of the spare tire. The spare tire fixing seat is provided with a structure for fixing the spare tire, such as a stud, a buckle, etc.

[0009] The adjustment structure includes a first adjustment hole arranged on the telescopic sleeve 1 and a second adjustment hole on the telescopic sleeve 2. The positions of the first adjustment hole and the second adjustment hole correspond to each other. At least two first adjustment holes and one second adjustment hole are provided, or at least one first adjustment hole and two second adjustment holes are provided. The first adjustment hole and the second adjustment hole are matched with bolts for fixing.

[0010] The first adjustment hole and the second adjustment hole cooperate with each other to adjust or fix the telescopic sleeve 1 and the telescopic sleeve 2. At least two first adjustment holes and one second adjustment hole or at least one first adjustment hole and two second adjustment holes are required. Only in the case of one-to-two, the adjustment can be made. Otherwise, no matter how to adjust, it can only be in the case of one-to-one. The relative position of the telescopic sleeve 1 and the telescopic sleeve 2 is actually fixed and cannot be adjusted. The first adjustment hole and the second adjustment hole are fastened with bolts after they correspond to each other. When the position needs to be adjusted, the bolts are unscrewed and the telescopic sleeve 2 is moved so that the new first adjustment hole or the second adjustment hole corresponds to the original second adjustment hole or the first adjustment hole to achieve adjustment.

[0011] The distance between the centers of the first adjusting hole and the second adjusting hole is greater than the radius.

[0012] If the distance between the hole centers is greater than the radius, the first adjustment hole and the second adjustment hole will appear as waist-shaped holes as a whole, which is not conducive to positioning.

[0013] The telescopic sleeve 1 and the telescopic sleeve 2 are both structures with a small upper part and a large lower part, and the shapes of the telescopic sleeve 1 and the telescopic sleeve 2 are adapted to each other.

[0014] The small-upper-large-lower structure allows the telescopic sleeve 2 to be hung on the telescopic sleeve 1. There is no need to worry about slipping or falling during operation, because the small-upper-large-lower structure naturally has a limiting effect in the horizontal direction, and gravity is used to achieve horizontal limiting of the telescopic sleeves 1 and 2.

[0015] The spare tire fixing seat is connected with a lens barrel, and the lens barrel moves telescopically along with the spare tire fixing seat and the telescopic sleeve 2.

[0016] The lens barrel is used to place the lens of the reversing image, and the lens barrel telescopes with the spare tire fixing seat and the telescopic sleeve 2. After the reversing image lens configured for the off-road vehicle is replaced with a wider spare tire, the lens is extended with the telescopic sleeve 2 and will not be blocked by the spare tire, so that the reversing image can also be used after replacing the wider spare tire.

[0017] The end of the lens barrel is provided with a downward inclined surface, and the inclined surface is provided with a lens hole.

[0018] The downward slope allows the reversing image lens to illuminate the ground and avoid obstruction; the lens hole is used to place the lens and let in light.

[0019] The connecting seat comprises an inner plate and an outer plate located in different planes, the inner plate is connected to the vehicle body, and the outer plate is connected to the second telescopic sleeve.

[0020] There is a distance between the planes where the inner plate and the outer plate are located, which realizes the protruding distance of the connecting seat and makes the spare tire rack protrude from the surface of the vehicle body. Because the surface of the vehicle body is uneven, if the spare tire rack is lifted or too close to the surface of the vehicle body, interference is likely to occur. Interference can be avoided after protruding a certain distance.

[0021] The inner plate and the outer plate are connected via a connecting inclined surface, and hollow holes are provided on the outer plate and the connecting inclined surface.

[0022] The inclined plane has certain structural strength in both directions. The connection between the inner and outer panels through the connecting inclined plane is beneficial to improving the overall structural strength; the hollow holes are used to reduce the overall weight and achieve a lightweight design.

[0023] Beneficial Effects

[0024] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0025] The design of the connecting seat realizes the effective connection between the spare tire rack and the vehicle body, ensuring the stability and convenience of the spare tire installation. The combined sliding and telescopic design of telescopic sleeve 1 and telescopic sleeve 2 makes the device highly flexible and adaptable. The distance between the spare tire fixing seat and the connecting seat can be adjusted according to actual needs, so as to meet the requirements of loading spare tires of different widths, greatly improving the practicality of the device. The existence of the adjustment structure enables telescopic sleeve 1 and telescopic sleeve 2 to be fixed after adapting to different spare tire widths, avoiding looseness or instability caused by changes in spare tire width, and further ensuring the safety and stability of the spare tire during driving. The fixing structure set on the spare tire fixing seat ensures the firm installation of the spare tire on the fixing seat, prevents the spare tire from displacement or falling off during vehicle driving, and enhances driving safety. This spare tire rack can carry spare tires of different widths; further, the lens barrel telescopes with the spare tire fixing seat and the telescopic sleeve 2. After the reversing image lens configured for the off-road vehicle is replaced with a wider spare tire, the lens is extended with the telescopic sleeve 2 and will not be blocked by the spare tire, so that the reversing image can also be used after the wider spare tire is replaced.

[0033] On the basis of the connecting seat 1, the telescopic sleeve 1 2 is welded to the connecting seat 1. The core function of the telescopic sleeve 1 2 is to provide a preliminary length adjustment space for the spare tire rack. Furthermore, the telescopic sleeve 2 3 is a slidably connected component, which is nested outside the telescopic sleeve 1 2 to form a telescopic system.

[0034] Combined with Figure 2 The adjustment structure includes a first adjustment hole 21 provided on the telescopic sleeve 1 2 and a second adjustment hole 31 provided on the telescopic sleeve 2 3. The positions of the first adjustment hole 21 and the second adjustment hole 31 correspond to each other.

The first adjustment hole 21 and the second adjustment hole 31 are matched and fixed with bolts. There are seven first adjustment holes 21 and seven second adjustment holes 31, and each of the first adjustment holes 21 and the second adjustment holes 31 is a continuous through hole, so as to realize continuous and precise displacement adjustment.

[0035] Combined with Figure 2 The distance between the centers of the first adjusting hole 21 and the second adjusting hole 31 is greater than the radius. When the distance is within twice the radius, there is an arc-shaped protrusion between the adjusting holes, which can be used for limiting bolts. When the distance is greater than twice the radius, the adjusting holes are separated from the adjusting holes, and the limiting of the bolts is no longer a problem, but the adjustment accuracy will be affected.

[0036] Combined with Figure 2 , 3 The end of the lens barrel 5 is provided with a downward inclined surface 51, and the inclined surface 51 is provided with a lens hole 52. The downward inclined surface 51 facilitates the lens of the reversing image to illuminate the ground to avoid obstruction; the lens hole 52 is used to place the lens and let in light.

[0037] Combined with Figure 3 The telescopic sleeve 1 2 and the telescopic sleeve 2 3 are both small at the top and large at the bottom, and the shapes of the telescopic sleeve 1 2 and the telescopic sleeve 2 3 are adapted. The telescopic sleeve 1 2 and the telescopic sleeve 2 3 are both trapezoidal profiles, and the middle is hollow for weight reduction and the line of the reversing image.
