DETAILED DESCRIPTION

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] Reference below Figure 1-Figure 4 The spare tire mounting structure assembly 100 according to the embodiment of the utility model is described, which realizes a larger space between the rear part of the bottom of the vehicle and the ground, improves the vehicle's passability, and reduces the airflow discharge resistance at the rear side of the bottom of the vehicle.

[0028] like Figure 1-Figure 4 A spare tire installation structure assembly 100 according to an embodiment of the utility model is described, comprising: a spare tire beam body 1 and a limiting bracket 3 .

[0029] Among them, the spare tire beam body 1 is connected between the two longitudinal beams 2 of the vehicle, and the spare tire beam body 1 is provided with a lifter mounting part 11, the lifter mounting part 11 is used to install the spare tire lifter, and the spare tire lifter is used to connect the spare tire; the limiting bracket 3 includes a bracket body part 32 and a limiting part 31, the bracket body part 32 is connected to the bottom of the spare tire beam body 1, the bracket body part 32 is constructed to extend along the front and rear direction of the vehicle and is arranged to be inclined upward from the front to the rear, and the limiting part 31 is connected to the front end bottom of the bracket body part 32 for limiting the spare tire.

[0030] In practice, the spare tire beam body 1 is connected between the two longitudinal beams 2 of the vehicle, and a lifter mounting portion 11 is provided on the spare tire beam body 1. The lifter mounting portion 11 is mainly used to install a spare tire lifter, and the spare tire lifter is used to connect the spare tire and raise the spare tire from the ground to the bottom of the vehicle, so that the spare tire contacts the spare tire limiting bracket 3 and the spare tire beam body 1; when the spare tire needs to be removed, the spare tire lifter is driven to make the spare tire drop to the ground along the contact point between the spare tire beam body 1 and the limiting bracket 3, so as to facilitate the removal of the spare tire and take out the spare tire for use.

[0031] Specifically, the bracket body 32 of the limiting bracket 3 is distributed along the front and rear directions of the vehicle, and the front end of the bracket body 32 is lower than the height of the rear end. The spare tire lifter is installed on the lifter mounting part 11, and the spare tire is connected to the spare tire lifter by a wire rope, so that the spare tire is raised to contact with the limiting part 31 of the limiting bracket 3 and is limited. That is, the spare tire is tilted on the spare tire beam body 1, and the spare tire is tilted and can use its own gravity to press and contact with the limiting part 31 of the limiting bracket 3. In addition, part of the spare tire is in contact with the spare tire beam body 1 for limiting. Therefore, after the spare tire is installed at the bottom of the vehicle, the position of the spare tire at the rear part of the vehicle chassis is high from the ground. As a result, a larger space is left for the rear of the vehicle, thereby improving the vehicle's passability and reducing the airflow discharge resistance at the rear side of the bottom of the vehicle.

[0032] In some embodiments, the rear side surface of the limiting portion 31 forms a pressing plane 311, which is arranged to be inclined from top to bottom and forward relative to the bottom surface of the bracket body 32, and is used for pressing contact with the spare tire.

[0033] The pressing plane 311 of the limiting part 31 is inclined toward the rear of the vehicle, and the pressing plane 311 is inclined downward, so that one position of the spare tire presses against the pressing plane 311, and another position can press against other positions of the spare tire beam body 1, so that at least two positions press against the spare tire, thereby preventing the spare tire from shaking after being installed on the lifter mounting part 11. In other words, the spare tire is located at a lower height in front of the vehicle, and the spare tire is tilted and uses its own gravity to press forward against the pressing plane 311 of the limiting part 31. Combined with the pressure of other positions of the spare tire, the spare tire can be limited after installation to prevent the spare tire from shaking.

[0034] In some embodiments, the limiting bracket 3 and the lifter mounting portion 11 are spaced apart and distributed on the spare tire beam body 1 along the width direction of the vehicle, and the pressure plane 311 is set to be inclined toward the rear side of the vehicle and toward one side of the width direction of the vehicle, and the inclination direction of the pressure plane 311 is toward the position where the spare tire is installed by the spare tire lifter.

[0035] In practice, the limiting bracket 3 is located between the two longitudinal beams 2 and is arranged to extend along the front-rear direction of the vehicle. The lifter mounting portion 11 is installed with the spare tire lifter, and the spare tire lifter is installed with the spare tire through a steel wire rope. The limiting bracket 3 is used to limit the edge position of the spare tire to prevent the spare tire from shaking.

[0036] Reference Figure 3 As shown, the pressing plane 311 of the limiting portion 31 of the limiting bracket 3 is generally inclined toward the rear side of the vehicle and toward one side in the width direction of the vehicle, and the pressing plane 311 is inclined and toward the position where the spare tire is installed on the spare tire lifter. That is to say, after the spare tire is installed on the lifter mounting portion 11, part of the spare tire is pressed against the pressing plane 311 of the limiting portion 31, which can limit the front of the spare tire and limit one side of the spare tire through the inclined pressing plane 311, thereby improving the stability of the spare tire.

[0037] Furthermore, the transition between the limiting portion 31 of the spare tire and the bracket body portion 32 is an arc-shaped transition, which can match the outer contour of the spare tire so that the limiting portion 31 of the spare tire and the bracket body portion 32 can press different positions of the spare tire and reduce the friction of the spare tire on the transition between the limiting portion 31 and the bracket body portion 32.

[0038] Moreover, the cross section of the limit bracket 3 is a "X"-shaped structure, and the interior of the limit bracket 3 is a hollow groove, which can reduce the weight of the limit bracket 3 and reduce the burden on the vehicle. Similarly, the spare tire beam body 1 is also constructed as a hollow groove, which can reduce the weight of the spare tire beam body 1 and the weight of the structure for installing the spare tire, thereby reducing the burden on the vehicle.

[0039] In some embodiments, the included angle between the bracket body portion 32 and the limiting portion 31 is a, and satisfies 110°≤a≤140°.

[0040] In practice, the angle between the bracket body 32 and the limiting portion 31 can be 120 degrees, so that a large angle of pressure is formed between the bracket body 32 and the limiting portion 31, that is, it can adapt to the transition between the side of the spare tire and the radial end face of the spare tire, and at the same time increase the contact area between the pressure plane 311 of the limiting portion 31 and the spare tire, thereby improving the reliability of the spare tire limitation.

[0041] In some embodiments, reinforcing plates 4 are connected to both ends of the bottom of the spare tire beam body 1, the distance between the limiting bracket 3 and one reinforcing plate 4 is smaller than the distance between the limiting bracket 3 and another reinforcing plate 4, the space between the other reinforcing plate 4 and the limiting bracket 3 is used to install the spare tire, and the other reinforcing plate 4 and the limiting portion 31 are both pressed against the spare tire.

[0042] In practice, there are two reinforcing plates 4 which are respectively connected to the two ends of the bottom of the spare tire beam body 1, and the reinforcing plates 4 are connected to the longitudinal beam 2. The distance between the limiting bracket 3 and one of the reinforcing plates 4 is relatively large. For example, the distance between the reinforcing plate 4 on the left side of the vehicle and the limiting bracket 3 is greater than the distance between the reinforcing plate 4 on the right side and the limiting bracket 3, and the lifter mounting portion 11 is located on the spare tire beam body 1 and on the left side of the limiting bracket 3.

[0043] Reference Figure 2 As shown, after the spare tire lifter is installed on the lifter mounting portion 11, the spare tire is installed on the spare tire lifter, and the reinforcing plate 4 on the left side of the vehicle and the limiting bracket 3 and the limiting portion 31 are used to limit the spare tire, wherein the reinforcing plate 4 and the limiting bracket 3 on the left side are respectively pressed and contacted with two positions of the spare tire, and since the spare tire is arranged at an angle, the lower end of the spare tire is pressed against the limiting portion 31, and the gravity of the spare tire itself can be used to make one position of the spare tire always pressed against the limiting portion 31, and the spare tire is pressed and contacted with the reinforcing plate 4, which can ensure the stability of the spare tire, and at the same time, after the spare tire is installed, the distance between the rear of the spare tire and the ground is larger, thereby improving the vehicle's passability and reducing the airflow discharge resistance at the rear side of the bottom of the vehicle.

[0044] In some embodiments, the reinforcement plate 4 extends along the outer side of the vehicle to the bottom of the longitudinal beam 2 and is connected to the longitudinal beam 2 .

[0045] In practice, the reinforcing plate 4 extends along the width direction of the vehicle and one end extends to the bottom of the longitudinal beam 2. The side of the reinforcing plate 4 close to the limiting bracket 3 is the inner side of the reinforcing plate 4, and the side away from the limiting bracket 3 is the outer side of the reinforcing plate 4; the outer side of the reinforcing plate 4 extends toward one side of the longitudinal beam 2 to form a connecting flange 42, and the connecting flange 42 is welded to the bottom of the longitudinal beam 2, and the reinforcing plate 4 is also welded to the bottom of the spare tire beam body 1; that is to say, the spare tire beam body 1 at this time can be properly installed in the lower position of the longitudinal beam 2, and after the reinforcing plate 4 is connected to the spare tire beam body 1, it forms a whole with the spare tire beam body 1, and the reinforcing plate 4 is connected to the bottom of the longitudinal beam 2 and the spare tire beam body 1 is connected to the inner wall of the longitudinal beam 2, thereby improving the strength of the connection between the spare tire beam body 1 and the longitudinal beam 2, thereby ensuring the reliability and stability of the entire spare tire beam body 1, so that the spare tire beam body 1 can be installed more stably.

[0046] Furthermore, the reinforcing plate 4 is a hollow cavity, which can reduce the weight of the entire spare tire mounting structure assembly. At the same time, the reinforcing plate 4 is located on the inner side of the longitudinal beam 2. When the vehicle is hit by an external force, the buffering effect of the side wall collision can be improved, and the impact of the collision on the spare tire beam body 1 and the spare tire can be reduced.

[0047] In some embodiments, an operating hole 41 is provided at the outer end of the reinforcing plate 4 , and the operating hole 41 is used for a rocker for removing the spare tire to extend into so as to remove the spare tire.

[0048] Among them, the end of the reinforcing plate 4 facing the inner side of the vehicle along the vehicle width direction is the inner side of the reinforcing plate 4, and the end of the reinforcing plate 4 facing the outer side of the vehicle along the vehicle width direction is the outer end of the reinforcing plate 4. The operating hole 41 at the outer end of the reinforcing plate 4 is used to extend a rocker to remove the spare tire installed on the spare tire lifter through the rocker.

[0049] The operating hole 41 of the embodiment of the utility model is located at the outer end of the reinforcing plate 4, and focuses on removing the spare tire from the side of the vehicle, and the specific method of removal is the same as the prior art; therefore, when removing and fixing the spare tire, the embodiment of the utility model removes and fixes it along the side of the vehicle, which is different from the prior art method of removing it at the rear of the vehicle. For example, when the rear space of the vehicle is limited, or when the vehicle is parked on an uphill section and the operator is at the rear for a long time to operate, there may be safety hazards. By removing the spare tire from the side, the problem of safety hazards when removing the spare tire at the rear when the rear space of the vehicle is limited or the vehicle is on an uphill section can be solved.

[0050] In some embodiments, the spare tire beam body 1 includes a middle area 12 and end areas 13 at both ends. The width of the middle area 12 narrows and then widens in the direction extending close to the longitudinal beam 2. The bottom of the middle area 12 is lower than the bottom of the end area 13, so that there is space at the bottom of the end area 13 for installing the reinforcing plate 4.

[0051] Among them, the middle area 12 of the spare tire beam main body 1 can be used to install the limit bracket 3, and a lifter installation part 11 is set, and the bottom of the middle area 12 of the spare tire beam main body 1 is lower than the end area 13 from the ground, which is convenient for disassembling and installing the spare tire; in addition, the bottom of the end area 13 and the bottom of the middle area 12 form an arc-shaped step transition, which can prevent stress concentration in the spare tire beam main body 1; and, the space reserved in the two end areas 13 of the spare tire beam main body 1 is used to install the reinforcement plate 4, and the bottom of the reinforcement plate 4 is slightly lower than the bottom of the middle area 12 of the spare tire beam main body 1, so as to contact and press with the spare tire side of the bottom of the spare tire beam main body 1.

[0052] In addition, the width of the middle area 12 narrows and then widens in the direction extending close to the longitudinal beam 2. The lifter mounting portion 11 can be set at the wider position of the middle area 12. The narrower position of the middle area 12 can be conveniently connected to the limit bracket 3, and the middle area 12 gradually widens close to the longitudinal beam 2, thereby improving the connection strength with the longitudinal beam 2, thereby ensuring the stability and reliability of the connection between the entire spare tire beam body 1 and the longitudinal beam 2.

[0053] In some embodiments, the bottom cross-section of the end region 13 is configured as an upwardly inclined curved shape, and the reinforcing plate 4 is cooperatively connected to the bottom of the end region 13 .

[0054] In practice, the end area 13 of the spare tire beam body 1 is inclined upward from the middle area 12 to the outer side in the vehicle width direction, and the end area 13 can be constructed as a curved bottom surface from the inside to the outside of the vehicle, and the connection between the reinforcing plate 4 and the bottom surface of the end area 13 is also a curved matching connection, which improves the connection stability between the end area 13 of the spare tire beam body 1 and the reinforcing plate 4. At the same time, when the side of the vehicle and the position of the reinforcing plate 4 are collided, the matching mode of the reinforcing plate 4 and the spare tire beam body 1 can effectively disperse the collision force, thereby improving the reliability and stability of the connection between the reinforcing plate 4, the spare tire beam body 1 and the longitudinal beam 2.

[0055] The utility model embodiment also discloses a vehicle, including the above-mentioned spare tire installation structure assembly 100, which realizes a larger space between the rear part of the vehicle bottom and the ground, improves the vehicle's passability, reduces the airflow discharge resistance at the rear side of the vehicle bottom, and improves the smoothness of vehicle driving.
