[0018] The following detailed explanation illustrates the specific implementation methods:
[0019] The markings in the accompanying drawings include: upper support frame 1, lower support frame 2, limiting component 3, first fixing component 4, pin shaft 41, second fixing component 5, hook 51, screw 52, locking nut 53, anti-loosening nut 54, reinforcing part 6, spare tire 7, vehicle rear floor 8, vehicle rear floor reinforcing crossbeam 9, vehicle tailgate frame inner panel 10, and C-type support frame structure 11.
[0020] The basic implementation examples are as follows: Figure 1 , Figure 2 and Figure 3 As shown: A new type of spare tire rack includes an upper support frame 1, a lower support frame 2, a limiting member 3, two first fixing members 4 and a second fixing member 5.
[0021] like Figure 1 As shown, the upper support frame 1 and the lower support frame 2 overlap and connect to form an X-shaped structure, and a space for placing the spare tire 7 is formed above the overlap and connection.
[0022] In this embodiment, the upper support frame 1 and the lower support frame 2 are made of Φ16 round tubes, which are bent and formed by process, and then welded together to form an X-shaped structure; as Figure 1 and Figure 4As shown, the bottom of the lower support frame 2 is a straight section, and the two sides of the straight section are curved sections, one end of which is used for hinged connection with the first fixing member 4, and the other end is used for detachable connection with the second fixing member 5; the bottom of the upper support frame 1 has a section protruding towards the spare tire 7 placement area at the overlapping connection position, which is used to avoid the straight section of the lower support frame 2 by means of the hollow space of the spare tire 7, so as to reduce the overall height of the spare tire frame, and the two sides of the upper support frame 1 are curved sections, one end of which is used for hinged connection with the first fixing member 4, and the other end is not connected with any component, which is used for limiting the transverse movement of the spare tire 7, and this design can minimize the overall size of the spare tire frame and adapt to vehicles with low loading platforms. The end of the upper support frame 1 and the lower support frame 2 connected with the first fixing member 4 has a V-shaped structure, which can reduce the contact area between the support frame and the spare tire 7 on the basis of stable support, and ensure the surface quality of the spare tire 7 under long-term contact. At the same time, the X-shaped structure formed by the overlapping connection of the upper support frame 1 and the lower support frame 2 is an asymmetric structure, and the specific subsequent connection method is described in detail.
[0023] As shown in Figure 2 and Figure 3 , the same side ends of the upper support frame 1 and the lower support frame 2 are respectively hinged with two first fixing members 4 to form two coaxial hinge points; the other end of the lower support frame 2 is detachably connected with the second fixing member 5 to form a detachable connection point.
[0024] In this embodiment, the hinge is connected by a pin shaft 41; the second fixing member 5 includes a hook 51, a screw rod 52 and two locking nuts 53, the screw rod 52 is installed at the other end of the lower support frame 2 through the two locking nuts 53, and the hole of the screw rod 52 is sleeved on the hook 51 to realize detachable screw connection, and a lock nut 54 is further added to further strengthen the fastening. This scheme uses the stability principle of triangle, and considers to set three spare tire frame suspension points, i.e. two hinge points and one detachable connection point, which has the smallest change to the original vehicle and the optimal development investment. As shown in Figure 5 and Figure 6 , the first fixing member 4, the second fixing member 5 and the limiting member 3 are all provided with a reinforcing part 6, and the structure of the reinforcing part of each component is determined in size, shape and installation angle according to the installation position of the component itself, so as to improve the installation stability.
[0025] The plane where the detachable connection point is located is below the planes where the two hinge points are located, and the detachable connection point deviates from one side of the center line of the two hinge points, and the positions of the detachable connection point and the lower support frame 2 do not interfere with the departure angle of the spare tire 7.
[0026] In this embodiment, from the top view, the detachable connection point is located between the two hinge points but deviates from one side of the center line of the two hinge points, and this side can be the outer side or the left side for easy taking and placing; in order to avoid the influence of the spare tire frame on the departure angle of such low loading platform WAN vehicles, the spare tire frame is designed through multiple scheme demonstrations, as shown in Figure 7As shown, the traditional spare tire frame structure is combined with the CC type support frame structure 11, and the support frame is calculated to have a departure angle of 15.5°. As shown in the Figure 8 As shown, in the present scheme, on the basis of the optimization design of other components, the upper support frame 1 and the lower support frame 2 adopt an X type structure, and the spare tire 7 is calculated to have a departure angle of 17.5°, which has no effect on the departure angle of the whole vehicle and meets the use requirements. Therefore, the present scheme design has obvious advantages for the vehicle with a low cargo platform.
[0027] The limiting piece 3 and the second fixing piece 5 are installed on the same side, and the plane where the limiting piece 3 is located is between the planes where the two hinge points and the detachable connection point are located, so as to limit the spare tire 7 placed between the upper support frame 1 and the limiting piece 3.
[0028] In the present embodiment, the connecting line of the limiting piece 3 and the two hinge points forms a triangle, specifically an isosceles triangle, so that the limiting force acting on the spare tire 7 is balanced, the spare tire 7 is prevented from moving upward, and the stability of the spare tire 7 is maintained. At the same time, the setting of the limiting piece 3 can form a gap between the spare tire 7 and the vehicle floor, which is not less than 30 mm, so as to prevent the interference between the spare tire 7 and the floor.
[0029] In actual application, the present scheme further provides a vehicle installed with the above-mentioned new type spare tire frame.
[0030] Specifically, as shown in Figure 2 , Figure 5 and Figure 6 , the above-mentioned new type spare tire frame is installed at the rear floor 8 of the vehicle, and the two first fixing pieces 4 are installed on the rear floor reinforcement cross beam 9 of the vehicle; the hooks 51 of the first fixing pieces 4 and the limiting piece 3 are installed on the inner panel 10 of the back door frame of the vehicle through the respective reinforcement parts 6, so as to improve the stability; the whole spare tire frame is connected with the two hinge points through the pin shaft 41, and since the two hinge points are coaxial, the spare tire frame can rotate upward and downward around the shaft, and the screw rod 52 is assembled at the other end of the lower support frame 2 through the two locking nuts 53. When the spare tire 7 is installed, after the spare tire 7 is placed in the built-in space of the spare tire frame, the spare tire frame is lifted and rotated upward around the hinge point, so that the hole of the screw rod 52 is sleeved on the hook 51, and then the screw rod 52 and the locking nuts 53 are tightened, so as to lock the spare tire 7; at the same time, in order to prevent the spare tire 7 from loosening during the running of the vehicle, a check nut 54 is added on the screw rod 52. After the installation of the spare tire 7, the first gap is formed between the two first fixing pieces 4 and the spare tire 7, so as to reduce the friction loss of the spare tire frame on the spare tire 7. The stability of the whole spare tire 7 is realized through the upper support frame 1 and the lower support frame 2, the two first fixing pieces 4 and the limiting piece 3, and the second fixing piece 5. When the spare tire 7 is disassembled, the check nut 54 and the locking nuts 53 are loosened in sequence, the screw rod 52 is taken out of the hook 51, the spare tire frame is rotated downward around the hinge point to contact the ground, and then the spare tire 7 can be taken out from the rear of the vehicle.
[0031] The embodiment provides a novel spare tire frame and a vehicle, which are based on the limited space of a vehicle, a low cargo platform, and the demand of mounting a spare tire frame; according to the structural characteristics of a pure electric VAN vehicle, the spare tire frame structure and the mounting position are optimized to reduce the modification of a platform vehicle; a rear-mounted spare tire frame is selected and arranged at a rear suspension of a vehicle frame, does not affect the appearance size of the vehicle, the loading and unloading space, the spare tire frame adopts a triangular connecting rod mechanism, the layout positions of two coaxial hinge joints and one detachable connecting joint are optimized, the calculation mode of a departure angle of the spare tire is changed while the stable mounting of the spare tire is realized, the departure angle is increased, the use requirement is met, and the scheme has obvious advantages for a vehicle with a low cargo platform.
