[0002] Depending on the vehicle model, the spare tire is usually placed under the trunk floor, hung under the rear of the vehicle, or fixed to the outside of the trunk door. For new energy vehicles, the compact body design and vehicle height also limit the storage location of the spare tire. Most new energy vehicles place the spare tire in the spare tire well under the trunk floor.
[0003] Chinese invention patent CN105835966B discloses an automobile spare tire mounting structure, which has strong load-bearing capacity, simple structure, convenient manufacturing process, and good modal stiffness performance, and can meet the requirements of lightweighting.
[0004] Currently, spare tires are mostly placed in the spare tire well by gravity. When the rubber layer of the spare tire is too tightly attached to the inner wall of the spare tire well, it is difficult to put in or take out the spare tire. If there is too large a gap between them, the spare tire is prone to shaking, posing a significant safety hazard. To address these issues, this utility model proposes a spare tire storage structure for new energy vehicles. Utility Model Content
[0005] The purpose of this invention is to provide a spare tire storage structure for new energy vehicles to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a spare tire storage structure for new energy vehicles, comprising:
[0007] The rear floor has a recessed center to form a spare tire pool. The spare tire pool is cam-shaped with one end having a larger inner diameter than the other end. A positioning frame is installed in the inner cavity of one end of the spare tire pool, and an anti-jump plate is fixed at the opening of the other end. A spare tire is placed in the inner cavity of the other end of the spare tire pool, and the anti-jump plate presses the spare tire down from top to bottom.
[0008] The positioning frame includes a connecting rod, and support rods are provided on both the upper and lower sides of the connecting rod. The support rods are configured in an arc shape and their middle part rests against the surface of the spare tire.
[0009] Preferably, two symmetrically distributed guide grooves are vertically formed on the inner wall of one end of the spare tire pool, and sliders are fixedly installed at both ends of the connecting rod. The two sliders are respectively located in the inner cavity of the two guide grooves and are slidably connected to them.
[0010] Preferably, a rubber pad is adhered to one side of the slider, and a boss is fixed to the other side of the slider. The two ends of the support rod are respectively rotatably connected to the two bosses.
[0011] Preferably, the upper and lower ends of the boss surface are fixedly connected to limit baffles, and the two limit baffles abut against the outer sides of the ends of the two support rods respectively.
[0012] Preferably, a handle is fixedly installed on the surface of the support rod, and a reset torsion spring is fixedly sleeved on the surface of the connecting rod, with the end of the reset torsion spring bent and fastened to the outside of the handle.
[0013] Preferably, a collar is fixedly installed on the surface of the connecting rod, and the surface of the collar has a notch, and the middle part of the reset torsion spring is located in the inner cavity of the collar.
[0014] Preferably, a roller is rotatably mounted on the middle of the support rod, and an annular groove is formed on the surface of the roller, with the concave arc of the annular groove matching the convex arc of the spare tire surface.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention features a spare tire storage compartment shaped like a cam with different radii at both ends. A positioning frame is vertically slidably installed at one end of the compartment, while an anti-jump plate is fixed at the opening at the other end.

[0023] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] Please see Figures 1 to 5 This utility model provides a technical solution:
[0025] Example 1: A spare tire storage structure for new energy vehicles, comprising: a rear floor 1.
[0026] Specifically, a spare tire well 2 is formed by a downward indentation in the middle of the rear floor 1. The spare tire well 2 is cam-shaped, with one end having a larger inner diameter than the other. A positioning frame 5 is installed in the inner cavity of one end of the spare tire well 2, and an anti-jump plate 4 is fixed at the opening of the other end. The anti-jump plate 4 is arc-shaped and covers the entire edge of the opening at the small end of the spare tire well 2. The outer and inner walls of the anti-jump plate 4 are two semicircles with different radii, and the radius of the inner wall of the anti-jump plate 4 is the same as the radius of the large end of the spare tire well 2. A spare tire 3 is placed in the inner cavity of the other end of the spare tire well 2. The anti-jump plate 4 is positioned from top to bottom. The spare tire 3 is pressed down, and the outer diameter of the spare tire 3 is consistent with the inner diameter of the small end of the spare tire pool 2. The spare tire 3 is vertically inserted into the inner cavity of the spare tire pool 2 from the large end of the spare tire pool 2 without being blocked by the anti-jump plate 4. Then, the spare tire 3 is pushed horizontally to enter the inner cavity of the small end of the spare tire pool 2. At this time, the anti-jump plate 4 can limit the edge of the spare tire 3 to prevent the spare tire 3 from jumping upward or even falling out of the inner cavity of the spare tire pool 2. The positioning frame 5 is inserted into the inner cavity of the large end of the spare tire pool 2 from top to bottom to horizontally position the spare tire 3.
[0027] Furthermore, the positioning frame 5 includes a connecting rod 51, with support rods 53 on both the upper and lower sides of the connecting rod 51. The support rods 53 are arc-shaped and their middle portions rest against the surface of the spare tire 3. Figure 1 and Figure 3It can be seen that the middle part of the support rod 53 abuts against the surface of the spare tire 3, and the two ends of the support rod 53 abut against the inner wall of the spare tire pool 2. After the positioning frame 5 positions the spare tire 3 as a whole, the surface of the spare tire 3 and the inner wall of the small end of the spare tire pool 2 remain in close contact. The friction prevents the spare tire 3 from rotating. When the spare tire 3 needs to be taken out, the positioning frame 5 is first removed, and then the spare tire 3 is pulled horizontally so that the spare tire 3 is located in the inner cavity of the large end of the spare tire pool 2. At this time, the surface of the spare tire 3 no longer adheres to the inner wall of the spare tire pool 2 and generates friction, so the spare tire 3 can be taken out more easily.
[0028] To prevent the positioning frame 5 from shifting in the horizontal direction, this application also has two symmetrically distributed guide grooves 21 vertically opened on the inner wall of one end of the spare tire pool 2. Both ends of the connecting rod 51 are fixedly installed with sliders 52. The two sliders 52 are respectively located in the inner cavity of the two guide grooves 21 and are slidably connected with them. The cooperation between the sliders 52 and the guide grooves 21 ensures that the positioning frame 5 can only slide up and down in the vertical direction and will not shift in the horizontal direction.
[0029] To facilitate the removal of the positioning frame 5 from the inner cavity of the spare tire well 2, this application also includes a rubber pad 521 adhered to one side of the slider 52 to increase the friction between the slider 52 and the inner wall of the guide groove 21, preventing the positioning frame 5 from moving upward and detaching from the inner cavity of the spare tire well 2. A boss 522 is fixed on the other side of the slider 52, and the two ends of the support rod 53 are rotatably connected to the two bosses 522 respectively. The support rod 53 can rotate around the line connecting the two ends as the rotation center. When the support rod 53 rotates, the middle part of the support rod 53 can move away from the spare tire 3 and create a gap. At this time, the rubber pad 521 no longer presses against the inner wall of the guide groove 21, and the positioning frame 5 can be removed from the inner cavity of the spare tire well 2 more easily.
[0030] To limit the rotation of the support rod 53, this application further includes limiting baffles 523 fixedly connected to both the upper and lower ends of the boss 522 surface. The two limiting baffles 523 respectively abut against the outer ends of the two support rods 53. Figure 3 The limiting baffle 523 shown is used to limit the rotation direction of the support rod 53. The two support rods 53 can rotate close to each other, and conversely, when the two support rods 53 rotate away from each other to the horizontal, they will be limited by the limiting baffle 523.
[0031] To prevent the support rod 53 from rotating arbitrarily and separating from the spare tire 3, this application also includes a handle 533 fixedly installed on the surface of the support rod 53, and a return torsion spring 54 fixedly sleeved on the surface of the connecting rod 51. The end of the return torsion spring 54 is bent and fastened to the outside of the handle 533. Figure 3 and Figure 4It is known that the return torsion spring 54 provides torque so that the handle 533 and the connecting rod 51 always tend to move away from each other. That is, the two support rods 53 are always in a horizontal position. Only when the user squeezes the two handles 533 to bring them closer together can the two support rods 53 move closer together and rotate. In other words, under normal circumstances, the support rods 53 are kept horizontal and press against the surface of the spare tire 3 to achieve a stable horizontal positioning of the spare tire 3. When it is necessary to remove the spare tire 3, the user only needs to squeeze the two handles 533 to drive the support rods 53 to rotate, which makes it easy to remove the positioning frame 5 and then remove the spare tire 3.
[0032] To install the reset torsion spring 54, this application also includes a collar 511 fixedly installed on the surface of the connecting rod 51, and a notch 512 is provided on the surface of the collar 511. The middle part of the reset torsion spring 54 is located in the inner cavity of the collar 511. The collar 511 is provided to fix and protect the middle part of the reset torsion spring 54, and at the same time to prevent the skin on the palm surface from being pinched by the reset torsion spring 54 when the user pinches the two handles 533. The notch 512 is provided to allow the end of the reset torsion spring 54 to protrude. In addition, the two ends of the reset torsion spring 54 are connected to the two handles 533 in a "<" shape. The reset torsion spring 54 drives the two handles 533 to move away from each other, so as to prevent the support rod 53 from rotating easily.
[0033] To reduce the friction between the support rod 53 and the spare tire 3, this application further includes a roller 531 rotatably mounted in the middle of the support rod 53. The surface of the roller 531 has an annular groove 532, and the concave arc of the annular groove 532 matches the convex arc of the surface of the spare tire 3. Figure 5 As shown, the roller 531 can only rotate in the middle of the support rod 53, which can reduce the contact friction between the support rod 53 and the spare tire 3, thus making it easier for the staff to remove the positioning frame 5 as a whole.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
