Technical Field

[0002] Some new energy vehicles, due to their rear-mounted electric drive and other reasons, do not have space for a spare tire compartment at the rear. The vehicle floor is relatively flat, so a spare tire mounting and fixing structure is needed to effectively install the spare tire, thereby helping to achieve vehicle weight reduction and improve the user experience.
[0003] Before using the spare tire mounting and fixing structure for some new energy vehicles, it is necessary to confirm that the spare tire specifications are compatible and clean the mounting location. During installation, first place the spare tire according to the direction, use the positioning pillars and limit plates for initial positioning, and then lock the center of the wheel hub. Some models also have lateral auxiliary fixing to ensure stability. Disassembly is the reverse operation: first unlock, then remove the spare tire, adapting to its special layout.
[0004] In the process of use, the spare tire installation and fixing structure of some new energy vehicles mostly adopts the screw fastening method, which requires tools and is cumbersome. In emergency situations, it is difficult to quickly unlock and retrieve the spare tire. When the vehicle is in motion, the spare tire will vibrate continuously due to road bumps. Traditional fixing structures are mostly rigid connections, lacking effective buffering and vibration reduction design, which cannot offset the vibration energy, causing the spare tire to loosen easily and affecting the fixing stability. Therefore, a new spare tire installation and fixing structure for new energy vehicles is proposed to solve the above problems. Utility Model Content

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] A spare tire mounting and fixing structure for new energy vehicles, referring to Figures 1 to 3 The system includes a support frame 1, with a clamp 2 fixedly connected to the outside of the support frame 1 to prevent wheel hub wear and reduce friction noise. A fixing mechanism 3 is fixedly connected to the outside of the clamp 2 to enhance the stability of the spare tire, prevent the spare tire from shifting when the vehicle is bumpy, and ensure driving safety. A vibration damping mechanism 4 is fixedly connected to the outside of the support frame 1 to buffer the impact of road bumps, reduce the vibration of the spare tire and the structure, extend the service life, and reduce noise. The fixing mechanism 3 includes a telescopic cylinder 31, which is fixedly connected to the outside of the support frame 1. The support frame 1 provides support for the telescopic cylinder 31. A transmission component 32 is fixedly connected to the drive end of the telescopic cylinder 31. The transmission component 32 transmits the linear motion of the telescopic cylinder 31 and converts it into a motion form suitable for the clamp 2 to clamp or release the spare tire. A fixed support column 33 is slidably connected to the outside of the transmission component 32 to provide support for the transmission component 32. A swing arm connecting rod 34 is rotatably connected to the outside of the fixed support column 33, which can drive the swing arm connecting rod 34 to move.
[0040] Specifically, the telescopic cylinder 31 is activated, which drives the transmission component 32 to move. The transmission component 32 slides on the fixed support column 33, causing the swing arm connecting rod 34 to rotate, which ultimately drives the clamp 2 to clamp or release the spare tire. The operation is simple and can quickly complete the loading and unloading of the spare tire. When the clamp 2 is fixed, it fits tightly and will not damage the wheel hub, and also reduces friction noise. When the vehicle is bumpy, the spare tire will not shake or shift, making driving safer. With the shock absorption mechanism 4, it can reduce the impact of road bumps, reduce the vibration of the spare tire and other components, make the parts more durable, reduce noise, and improve the comfort of driving.
[0041] The two ends of the swing arm connecting rod 34 are rotatably connected to rotating support columns 35. When the sliding column 325 slides, it drives the swing arm connecting rod 34 to swing. Rotating support column 36 is rotatably connected to the outside of rotating support column 35. When rotating support column 35 rotates, it can drive rotating support column 36 to rotate. Fixed support column 37 is rotatably connected to the outside of rotating support column 36. Fixed support column 37 provides a support point for the rotation of rotating support column 36. The transmission assembly 32 includes a transmission plate 321. The outside of the transmission plate 321 is fixedly connected to the drive end of the telescopic cylinder 31. The transmission plate 321 bears the driving force of the telescopic cylinder 31. The transmission plate 321 is rotatably connected to a transmission link 322, and the two ends of the transmission link 322 are rotatably connected to a first rotating support column 323. The linear motion of the transmission plate 321 is converted into the rotation of the first rotating support column 323 through the transmission link 322. A fixed support plate 324 is rotatably connected to the outside of the first rotating support column 323. Under the drive of the transmission link 322, the first rotating support column 323 rotates, thereby pushing the fixed support plate 324 to move. A sliding column 325 is fixedly connected to the outside of the fixed support plate 324. The fixed support plate 324 can support and fix the sliding column 325, and at the same time convert the rotation of the first rotating support column 323 into the sliding of the sliding column 325.
[0042] Specifically, the telescopic cylinder 31 is activated, which drives the transmission plate 321 to move. The transmission plate 321 converts the linear motion into the rotation of the first rotating support column 323 through the transmission connecting rod 322. The rotating first rotating support column 323 pushes the fixed support plate 324, which in turn drives the sliding column 325 to slide on the first fixed support column 33. When the sliding column 325 slides, it drives the swing arm connecting rod 34 to swing. The swing arm connecting rod 34 causes the second rotating support column 35 at both ends to rotate. The second rotating support column 35 then drives the third rotating support column 36 to rotate, ultimately allowing the clamp 2 to clamp or release the spare tire. The second fixed support column 37 provides stable support for the third rotating support column 36. The clamp 2 fits tightly without rubbing the wheel hub and reduces noise. When the vehicle is bumpy, the spare tire does not shake, making it safer. The transmission of each component is smooth, and the vibration damping mechanism 4 can reduce impact and vibration.
[0043] The external of the rotating support column 323 is rotatably connected to the outside of the transmission plate 321. Driven by the fixed support plate 324, the sliding column 325 slides inside the fixed support column 33, thereby pushing the swing arm connecting rod 34 to move. The external of the sliding column 325 is rotatably connected to the outside of the fixed support column 33. The fixed support column 33 provides a sliding track and support for the sliding column 325. The external of the rotating support column 35 is rotatably connected to the outside of the clamp 2. When the rotating support column 35 rotates, it realizes the clamping or releasing action of the clamp 2. The external of the rotating support column 36... Rotary support column 36 is rotated and connected to the outside of clamp 2, further assisting clamp 2 in clamping or releasing the spare tire. Fixed support column 2 is fixedly connected to the outside of fixed support column 1 33, providing a support point for the rotation of rotating support column 36, ensuring the stability of rotating support column 36 during rotation, thereby ensuring the reliability of clamp 2's operation. The swing arm connecting rod 34 is rotated and connected to the outside of sliding column 325. When sliding column 325 slides, it drives swing arm connecting rod 34 to swing, thereby pushing rotating support column 2 35 to move.
[0044] Specifically, the fixed support plate 324 drives the sliding column 325 to slide within the fixed support column 33, thereby pushing the swing arm linkage 34 to swing. The swing arm linkage 34 drives the rotating support column 35 to rotate. At the same time, the rotating support column 36 rotates synchronously under the support of the fixed support column 37. The rotating support column 323 is connected to the transmission plate 321 to ensure overall linkage, jointly realizing the clamping or releasing action of the two clamps on the spare tire. The fixed support column 33 provides a stable sliding track for the sliding column 325 to avoid sliding deviation. The fixed support column 37 provides a reliable support point for the rotating support column 36 to ensure smooth rotation, which can enhance the clamping stability of the spare tire, prevent the spare tire from shaking during use, and adapt to the clamping requirements of different specifications of spare tires.
[0045] Reference Figure 2 and Figure 4 The vibration damping mechanism 4 includes a sliding piston 41, which is fixedly connected to the outside of the support frame 1. The support frame 1 provides support for the sliding piston 41. A buffer sleeve 42 is slidably connected to the outside of the sliding piston 41. The sliding piston 41 is cylindrical in shape and cooperates with the inner wall of the buffer sleeve 42 to ensure that the sliding piston 41 slides smoothly within it. A spring fixing column 43 is rotatably connected to the outside of the sliding piston 41. The sliding piston 41 provides support for the spring fixing column 43. A telescopic spring 44 is sleeved on the outside of the spring fixing column 43. When the spring fixing column 43 moves with the sliding piston 41, the telescopic spring 44 will be compressed or stretched. Rotating blocks 45 are fixedly connected to both ends of the spring fixing column 43. The rotating blocks 45 provide support for the spring fixing column 43.
[0046] Specifically, the sliding piston 41 is externally fixedly connected to the support frame 1, which provides stable support for the sliding piston 41. The sliding piston 41 is externally slidably connected to the buffer sleeve 42, and the sliding piston 41 is cylindrical in shape, which can cooperate with the inner wall of the buffer sleeve 42 to ensure that the sliding piston 41 slides smoothly within the buffer sleeve 42. The sliding piston 41 is also rotatably connected to the spring fixing column 43, which provides installation support for the spring fixing column 43. A telescopic spring 44 is sleeved on the outside of the spring fixing column 43. When the spring fixing column 43 moves with the sliding piston 41, the telescopic spring 44 will be compressed or stretched accordingly to generate a buffering force. At the same time, rotating blocks 45 are fixedly connected to both ends of the spring fixing column 43, which further provides support for the spring fixing column 43 and ensures its stability during movement, thereby allowing the vibration damping mechanism 4 to stably perform its vibration damping effect.
[0047] Rotating block 45 is rotatably connected to rotating support column 46. When rotating block 45 drives rotating support column 46 to rotate, the movement of rotating block 45 can be further transmitted. Sliding piston 41 is fixedly connected to vibration damping shell 47, which provides support for sliding piston 41. Rotating support column 46 is fixedly connected to the outside of sliding piston 41, which provides support for rotating support column 46. Vibration damping shell 47 is fixedly connected to the outside of support frame 1, which provides support for vibration damping shell 47.
[0048] Specifically, the rotating block 45 is externally rotatably connected to the rotating support column 46. When the rotating block 45 drives the rotating support column 46 to rotate, it can further transmit motion. The sliding piston 41 is externally fixedly connected to the vibration damping shell 47, which provides support for the sliding piston 41. The rotating support column 46 is externally fixedly connected to the outside of the sliding piston 41, which provides support for the rotating support column 46. The vibration damping shell 47 is externally fixedly connected to the outside of the support frame 1, which provides support for the vibration damping shell 47. All components cooperate with each other to ensure smooth motion transmission of the vibration damping mechanism 4, thereby improving the overall structural stability and vibration damping effect.
[0049] The implementation principle of this application embodiment is as follows: When the telescopic cylinder 31, supported by the fixed support column 33, starts to run, the transmission plate 321 drives the transmission connecting rod 322 to move, thereby driving the sliding column 325 to slide on the fixed support column 33 by rotating the support column 323 and the fixed support plate 324. When the sliding column 325 starts to slide, the swing arm connecting rod 34 drives the rotating support column 35 to move, thereby causing the clamp 2 to move around the rotating support column 36 on the fixed support column 37, thereby achieving rapid access to the spare tire, which can shorten the vehicle's dwell time on dangerous road sections, reduce the risk of accidents, improve driving safety, and ensure emergency travel.
[0050] When the car vibrates, the vibration is transmitted to the sliding piston 41 by the damping housing 47, causing the sliding piston 41 to slide inside the buffer sleeve 42 and compress the air inside the buffer sleeve 42. At the same time, when the sliding piston 41 slides up and down, the telescopic spring 44 sleeved outside the two spring fixing columns 43 undergoes elastic deformation. The degree of deformation of the telescopic spring 44 is changed by the rotating block 45 and the rotating support column 46. Both of these factors work together to achieve a vibration reduction effect, thereby reducing vibration transmission, protecting the spare tire, extending the service life of the spare tire and the fixed structure, and ensuring that the spare tire can function normally and reliably when it is needed.
[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
