[0001] This utility model relates to the field of wheel hub technology, specifically to a steel rim structure and its wheel hub. Background Technology
[0002] The wheel rims are a crucial component of electric tricycles, typically made of high-strength steel or aluminum alloy. High-strength steel rims offer superior load-bearing capacity, maintaining stable operation even under heavy loads and preventing deformation or damage. Aluminum alloy rims, on the other hand, are lighter and stronger, contributing to improved overall vehicle stability.
[0003] In the existing technology, due to the lack of effective protective measures on the outer side of the wheel hub steel rim of electric tricycles, coupled with the fact that novice drivers are not proficient in operating the tricycle, the steel rim is prone to scratching or being damaged by roadside obstacles due to misoperation, which affects the service life of the wheel hub steel rim. Utility Model Content
[0004] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a steel rim structure and its hub to solve the problem mentioned in the background art that the outer side of the wheel hub steel rim lacks effective protective measures, and that misoperation can easily lead to the steel rim being scratched or damaged by roadside obstacles.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A steel ring structure, comprising:
[0007] Steel rims for tricycles;
[0008] The protective structure is installed on the steel rim of the tricycle to protect the outside of the steel rim.
[0009] A buffer structure, placed on a protective structure, is used to buffer the compression and impact on the protective structure.
[0010] An adjustment structure is arranged on the protective structure and used in conjunction with the buffer structure to adjust the distance between the protective structure and the tricycle rim.
[0011] The protective structure includes a guard assembly for blocking the side of the tricycle's steel rim and an installation assembly for fixing the position of the guard assembly. The guard assembly is detachably installed inside the tricycle's steel rim and includes a ring frame, several guide rods, a ring guard plate, and a rubber buffer pad. The several guide rods are slidably installed inside the ring frame. The ring guard plate is arranged at one end of the guide rod and located on one side of the tricycle's steel rim. The rubber buffer pad is arranged on the side of the ring guard plate facing the tricycle's steel rim and is located between the ring guard plate and the tricycle's steel rim.
[0012] Preferably, the mounting components include:
[0013] Several threaded posts are evenly welded to the inner wall of the tricycle's steel rim;
[0014] Several fixed screws pass through the ring frame and are threaded into the corresponding threaded posts.
[0015] Preferably, the buffer structure is arranged in multiple groups, and each group of buffer structures includes:
[0016] The threaded sleeve is slidably installed inside the ring frame;
[0017] A buffer spring is slidably sleeved on a threaded sleeve rod, with one end of the buffer spring arranged on a ring frame;
[0018] An annular compression plate is arranged at one end of the threaded sleeve and the buffer spring, and is used to compress the buffer spring during movement;
[0019] The connecting screw is threaded into the threaded sleeve and rotatably mounted inside the annular retaining plate.
[0020] Guide components are used to limit the direction of movement of the threaded sleeve.
[0021] Preferably, the guide assembly includes a limiting slide hole formed inside the annular frame, and the threaded sleeve is slidably installed inside the limiting slide hole to guide the movement direction of the threaded sleeve.
[0022] Preferably, the buffer structure further includes a limiting component arranged on the threaded sleeve rod to limit the movement distance of the threaded sleeve rod.
[0023] Preferably, the limiting component includes an annular baffle disposed at one end of the threaded sleeve, the annular baffle contacting one side of the annular frame.
[0024] Preferably, the adjustment structure includes:
[0025] A knob is located at one end of the connecting screw;
[0026] The limiting ring is fixedly sleeved on the connecting screw and contacts one side of the annular baffle plate;
[0027] The threaded hole is located inside the threaded sleeve, and the connecting screw is threaded into the threaded hole.
[0028] This utility model also provides a wheel hub, including the aforementioned steel rim structure.
[0029] The beneficial effects of this utility model are as follows:
[0030] This invention relates to a circular guard plate installed on the side of a tricycle rim. This guard plate protects the rim during use. When the tricycle rim approaches a roadside fence or obstacle, it first contacts the obstacle, causing the guard plate to compress a buffer spring. The buffer spring cushions the pressure on the guard plate, reducing damage. If the guard plate continues to be under pressure, it will cause a rubber buffer pad to contact the surface of the tricycle rim, preventing direct pressure and damage. This improves the protection of the tricycle rim.
[0031] This invention allows for the removal of worn and damaged annular guard plates by rotating the corresponding knob and unscrewing it from the threaded sleeve, so that new annular guard plates can be replaced. Furthermore, by completely unscrewing the fixing screw from the threaded post, the device can be completely removed from the tricycle's steel rim, allowing for installation and removal according to user habits.

[0040] 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.
[0041] Example 1:
[0042] like Figures 1 to 5 As shown, this utility model provides a steel ring structure, including: a tricycle steel ring 1 and a protective structure arranged on the tricycle steel ring 1 for protecting the outside of the tricycle steel ring 1, and a buffer structure arranged on the protective structure for buffering the compression and impact received by the protective structure.
[0043] The protective structure includes a guard assembly for blocking the side of the tricycle's steel rim 1 and a mounting assembly for fixing the position of the guard assembly.
[0044] The protective assembly includes a ring frame 2 that can be detachably installed inside the tricycle steel rim 1, several guide rods 201 that are slidably installed inside the ring frame 2, and a ring guard plate 202 arranged at one end of the guide rods 201 and located on one side of the tricycle steel rim 1. If the outer side of the tricycle steel rim 1 is close to an obstacle on the roadside during use, the ring guard plate 202 on one side will contact the obstacle first, and the ring guard plate 202 will protect the tricycle steel rim 1.
[0045] The protective assembly also includes a rubber buffer pad 203 arranged on one side of the annular protective plate 202 to buffer the contact between the tricycle steel rim 1 and the annular protective plate 202. The rubber buffer pad 203 is located between the annular protective plate 202 and the tricycle steel rim 1. If the annular protective plate 202 is continuously compressed, the rubber buffer pad 203 will first contact the surface of the tricycle steel rim 1 to buffer the contact between the annular protective plate 202 and the tricycle steel rim 1.
[0046] The installation components include several threaded posts 3 uniformly welded to the inner wall of the tricycle steel rim 1, and a fixing screw 301 that passes through the annular frame 2 and is threaded into the corresponding threaded post 3. By rotating the fixing screw 301 and unscrewing it from the threaded post 3, the annular frame 2 and the annular guard plate 202 can be completely removed from the tricycle steel rim 1.
[0047] The buffer structure is arranged in multiple sets. Each set of buffer structures includes a threaded sleeve 4 slidably installed inside the annular frame 2, a buffer spring 401 slidably sleeved on the threaded sleeve 4, one end of the buffer spring 401 being arranged on the annular frame 2, an annular compression plate 402 arranged on the threaded sleeve 4 and one end of the buffer spring 401 for squeezing the buffer spring 401 during movement, a connecting screw 403 threadedly installed inside the threaded sleeve 4 and rotatably installed inside the annular baffle 202, and a guide component for limiting the movement direction of the threaded sleeve 4. The annular baffle 202 will drive the connecting screw 403 to move, so that the connecting screw 403 drives the threaded sleeve 4 to slide inside the limiting sliding hole 404. At the same time, the threaded sleeve 4 will drive the annular compression plate 402 to squeeze the buffer spring 401, and the buffer spring 401 will buffer the impact force received by the annular baffle 202.
[0048] Specifically, the guide assembly includes a limiting slide hole 404 opened inside the ring frame 2 to guide the movement direction of the threaded sleeve 4. The threaded sleeve 4 is slidably installed inside the limiting slide hole 404. When the connecting screw 403 moves, it can drive the threaded sleeve 4 to slide inside the limiting slide hole 404, thereby limiting the movement direction of the threaded sleeve 4.
[0049] The buffer structure also includes a limiting component arranged on the threaded sleeve 4 to limit the movement distance of the threaded sleeve 4.
[0050] Specifically, the limiting component includes an annular baffle 405 disposed at one end of the threaded sleeve 4. The annular baffle 405 contacts one side of the annular frame 2. The annular baffle 405 prevents the threaded sleeve 4 from coming loose from the inside of the annular frame 2.
[0051] Example 2:
[0052] Based on Example 1, in order to facilitate the replacement of the damaged annular guard plate 202 and to adjust the distance between the annular guard plate 202 and the tricycle steel rim 1 according to usage habits, an adjustment structure for adjusting the distance between the protective structure and the tricycle steel rim 1 is arranged on the protective structure.
[0053] The adjustment structure includes a knob 5 arranged at one end of the connecting screw 403, a limiting ring 501 fixedly sleeved on the connecting screw 403 and in contact with one side of the annular baffle plate 202, a threaded hole 502 opened inside the threaded sleeve 4, and the connecting screw 403 threadedly installed in the threaded hole 502.
[0054] This utility model also provides a wheel hub, including a steel rim structure.
[0055] Working principle: When the tricycle steel rim 1 is in use, if the outer side approaches an obstacle on the roadside, the annular guard plate 202 on one side will first contact the obstacle. This causes the guide rod 201 to slide inside the annular frame 2 under pressure. Simultaneously, the annular guard plate 202 will move the connecting screw 403 via the limiting ring 501, causing the connecting screw 403 to slide the threaded sleeve 4 inside the limiting sliding hole 404. The threaded sleeve 4 will also cause the annular compression plate 402 to compress the buffer spring 401, thus buffering the impact force on the annular guard plate 202. If the annular guard plate 202 continues to be compressed, the rubber buffer pad 203 will first contact the surface of the tricycle steel rim 1, thus protecting the annular guard plate 202 and the tricycle steel rim 1. To buffer the contact and prevent the annular guard plate 202 from directly pressing against the tricycle rim 1 and causing damage, if the damaged annular guard plate 202 needs to be replaced, press the threaded sleeve 4 and rotate the corresponding knob 5. The knob 5 will drive the connecting screw 403 to rotate. The engagement of the limiting ring 501 and the knob 5 will prevent the connecting screw 403 from coming loose from the inside of the annular guard plate 202. The continuously rotating connecting screw 403 can move through the thread engagement with the threaded hole 502. Finally, the connecting screw 403 can be completely unscrewed from the threaded sleeve 4, so that the connecting screw 403 drives the annular guard plate 202 to completely detach from one side of the tricycle rim 1, thus completing the disassembly of the annular guard plate 202 for replacement with a new one.
[0056] By rotating the fixing screw 301 and unscrewing it from the threaded post 3, the connection restriction between the tricycle steel rim 1 and the ring frame 2 can be released. At this time, the ring frame 2 and the ring guard plate 202 can be completely removed from the tricycle steel rim 1 for loading and unloading as needed.
[0057] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
