[0007] To achieve the above objectives, this utility model provides the following technical solution: a dustproof structure for a bicycle seat, comprising a seat body, a storage shell, a bottom cover, and a top cover. The lower end of the seat body is provided with a seat support rod. The storage shell is located below the seat body. The lower end of the storage shell is provided with a base. The seat support rod passes through the storage shell and the base. A locking rod is provided on the base. The locking rod passes through the base and one end abuts against the seat support rod. The locking rod is threadedly connected to the base.

[0008] The storage shell has an internal slot with multiple drainage holes at the bottom. The bottom sleeve and top sleeve are placed inside the slot. The bottom sleeve has an annular positioning plate that is penetrated and fixed to the bottom of the slot by the seat support rod. One side of the bottom sleeve is connected to one side of the top sleeve, and the periphery of the bottom sleeve is connected to the periphery of the top sleeve by a zipper. The seat body is wrapped by the bottom sleeve and the top sleeve, with the top sleeve located above the bottom sleeve.

[0009] To improve the stability of the storage shell during use, the present invention includes an improvement where one end of the locking rod is provided with an anti-slip pad that contacts the seat support rod.

[0010] To improve the sealing performance at the annular baffle, the present invention includes an annular baffle inside the storage shell, and a sealing ring on the periphery of the annular baffle, which contacts the inner wall of the storage shell.

[0011] To facilitate the disassembly of the annular baffle, the present invention includes an improvement in that the upper end of the annular baffle is provided with multiple toggle blocks.

[0012] Furthermore, the improvements of this utility model include that the storage shell and the base are an integrated structure, and the storage shell, the base and the annular baffle are all made of plastic, the bottom sleeve and the top sleeve are both made of TPU material, and the zipper is a waterproof zipper.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a dustproof structure for bicycle seats, which has the following beneficial effects:

[0015] Unlike traditional single-coverage dustproof structures, this solution utilizes a zipper-style closure design for the bottom and top covers to provide full protection for the seat body and the connection between the seat surface and the support rod. This effectively prevents dust and mud from seeping in through gaps, avoiding aging of the internal springs and cushioning materials due to contamination and extending the seat's lifespan. The combination of waterproof zippers and TPU material can withstand rain splashes, ensuring protective performance in harsh weather conditions. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-4This utility model discloses a dustproof structure for bicycle seats, including a seat body 1, a storage shell 3, a bottom sleeve 6, and a top sleeve 11. The lower end of the seat body 1 is provided with a seat support rod 2. The storage shell 3 is located below the seat body 1. The lower end of the storage shell 3 is provided with a base 4. The seat support rod 2 passes through the storage shell 3 and the base 4. The base 4 is provided with a locking rod 5. The locking rod 5 passes through the base 4 and one end abuts against the seat support rod 2. The locking rod 5 is threadedly connected to the base 4.

[0023] The storage shell 3 has an internal slot, and the bottom of the slot has multiple drainage holes 7. The bottom sleeve 6 and the top sleeve 11 are placed inside the slot. The lower end of the bottom sleeve 6 has an annular positioning plate 14 that is penetrated by the seat support rod 2 and fixed to the bottom of the slot. One side of the bottom sleeve 6 is connected to one side of the top sleeve 11, and the periphery of the bottom sleeve 6 is connected to the periphery of the top sleeve 11 by a zipper 12. The seat body 1 is wrapped by the bottom sleeve 6 and the top sleeve 11, and the top sleeve 11 is located above the bottom sleeve 6.

[0024] The storage shell 3 and the base 4 are an integrated structure, and the storage shell 3, the base 4 and the annular baffle 8 are all made of plastic. The bottom sleeve 6 and the top sleeve 11 are both made of TPU material, and the zipper 12 is a waterproof zipper 12.

[0025] Storage Case 3 Installation Process:

[0026] One end of the locking rod 5 is provided with an anti-slip pad 13 that contacts the seat support rod 2.

[0027] After removing the seat support 2 from the frame, pass it through the pre-drilled channel at the bottom of the storage shell 3 and the center of the base 4. Then, rotate the locking lever 5, and through the threaded drive, make the anti-slip pad 13 at one end of it tightly abut against the seat support 2, thereby fixing the storage shell 3 to the bottom of the seat support 2. During this process, the integrated structure of the storage shell 3 and the base 4 ensures installation stability and prevents shaking during riding.

[0028] Dust cover unfolding and wrapping:

[0029] The storage shell 3 has an annular baffle 8 inside, and a sealing ring 9 is provided on the periphery of the annular baffle 8. The sealing ring 9 contacts the inner wall of the storage shell 3, and a plurality of actuating blocks 10 are provided at the upper end of the annular baffle 8.

[0030] When dust protection is needed for the bicycle seat, first remove the annular baffle 8 from the slot in the storage shell 3 using the lever 10, then remove the folded bottom cover 6 and top cover 11. Unfold the bottom cover 6 from under the seat body 1, allowing the annular positioning plate 14 to be fitted onto the seat support rod 2 and fixed to the bottom of the slot. Then, cover the top cover 11 over the seat body 1, ensuring that the side connections of the two are aligned. Pull the waterproof zipper 12 on the perimeter to close the bottom cover 6 and top cover 11, forming a fully enclosed structure for the seat body 1. The elastic properties of the TPU material allow it to closely conform to the curved surface of the seat, reducing gaps.

[0031] Waterproofing and drainage mechanisms:

[0032] In case of rain, rainwater seeps into the hollow trough, and the drainage hole 7 at the bottom of the trough can drain the accumulated water in time, preventing moisture from accumulating inside. The annular baffle 8, together with the surrounding sealing ring 9, is embedded in the inner wall of the storage shell 3, which can further prevent external dust and rainwater from entering the interior of the storage shell 3, improving the protective sealing performance.

[0033] Storage and disassembly:

[0034] Before riding, when the dust cover needs to be removed, unzip the waterproof zipper 12, fold the top cover 11 and the bottom cover 6 and place them into the slot of the storage shell 3, then insert the annular baffle 8 to secure them and prevent the dust cover from shaking during riding. If the storage shell 3 needs to be removed as a whole, rotate the locking rod 5 in the opposite direction to release the restriction on the seat support 2, and then remove the seat support 2 from the frame. Because there is frictional damping force between the locking rod 5 and the base 4, the locking rod 5 will not loosen due to vibration when it is not under force.

[0035] The locking rod 5 and the anti-slip pad 13 work together to quickly secure the storage shell 3, allowing for tool-free installation and removal, and are compatible with seat supports 2 of different car models. The TPU dust cover is highly elastic and wear-resistant, does not easily deform after repeated folding, and has strong weather resistance, allowing for stable use in environments ranging from -40℃ to 80℃; the plastic storage shell 3 and base 4 offer advantages in terms of lightweight and impact resistance, balancing practicality and cost control.

[0036] The slotted structure of the storage shell 3 allows the dust cover to be folded and stored under the seat without taking up extra riding space, making it suitable for daily commuting and outdoor storage. The toggle block 10 design of the ring baffle 8 makes it easy for users to remove the dust cover for cleaning. The detachable component structure reduces maintenance difficulty and improves ease of use.
