Description

Technical Field

[0001] This utility model belongs to the field of shared bicycle technology, and in particular relates to a chain protection cover for shared bicycles. Background Technology

[0002] Traditional fully enclosed chain covers require complete disassembly to inspect the chain or replace parts, which is time-consuming and labor-intensive, affecting the operational efficiency of shared bicycles.

[0003] Limitations of segmented shields: Existing segmented designs only support partial opening and cannot simultaneously meet the needs of zonal maintenance of the middle (chainring area) and both ends (cassette / rear derailleur area).

[0004] Most chain covers only have basic dust and dirt protection functions and have a single opening method (such as a full opening or a fixed half cover), which cannot be adapted to the high-frequency maintenance scenarios of shared bicycles.

[0005] Therefore, there is an urgent need to design a chain protection cover for shared bicycles to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a chain protection cover for shared bicycles, which has the advantages of being able to be inspected and repaired quickly by section, and solves the problems mentioned in the background art.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0030] The following is a reference to the appendix. Figure 1 To be continued Figure 6 This utility model describes a chain protection cover for shared bicycles.

[0031] Traditional fully enclosed chain covers require complete disassembly to inspect the chain or replace parts, which is time-consuming and labor-intensive, affecting the operational efficiency of shared bicycles.

[0032] Limitations of segmented shields: Existing segmented designs only support partial opening and cannot simultaneously meet the needs of zonal maintenance of the middle (chainring area) and both ends (cassette / rear derailleur area).

[0033] Most chain covers only have basic dust and dirt protection functions and have a single opening method (such as a full opening or a fixed half cover), which cannot be adapted to the high-frequency maintenance scenarios of shared bicycles.

[0034] Therefore, this shared bicycle chain protection cover includes two connectors 2 and a first cover 1. The first cover 1 is located between the two connectors 2. The first cover 1 can rotate relative to the two connectors 2 to open the first cover 1 for inspection of the middle part of the chain. A second cover 3 is provided on the connectors 2. When the second cover 3 is opened, the second cover 3 slides along the connectors 2 to the end away from the first cover 1. When the second cover 3 slides to the first position, the second cover 3 rotates relative to the connectors 2 to open the second cover 3 for inspection of any end of the chain.

[0035] When maintenance is required in the middle of the chain, rotate the first cover 1 to expose the chain in the chainring area for maintenance. When maintenance is required at any end of the chain, first slide the second cover 3. After the second cover 3 slides to the first position, rotate the second cover 3 to expose the freewheel or derailleur area. This allows for independent maintenance of different sections, eliminating the need for complete disassembly and significantly reducing maintenance time.

[0036] Regarding the rotation mode of the second cover 3 when it slides to the first position, a first connecting block 23 is fixedly connected to the connecting piece 2, a first rotating rod 24 is fixedly connected to the first connecting block 23, a second connecting block 33 is fixedly connected to the second cover 3, and the second connecting block 33 can be rotatably connected to the first rotating rod 24. When the second cover 3 slides to the first position, the second connecting block 33 is connected to the first rotating rod 24.

[0037] The second connecting block 33 has a through hole 34, which is rotatably connected to the first rotating rod 24 through the through hole 34. The second connecting block 33 has an opening 35, which is connected to the through hole 34. The first rotating rod 24 can enter or move away from the through hole 34 through the opening 35. The second connecting block 33 has a first state and a second state.

[0038] When the second connecting block 33 is in the first state, the second connecting block 33 is separated from the first rotating rod 24;

[0039] When the second connecting block 33 is in the second state, the second cover 3 slides to the first position, the first rotating rod 24 enters the through hole 34 through the opening 35, and the second connecting block 33 is rotatably connected to the first rotating rod 24.

[0040] Regarding the sliding method of the second cover 3 and the connecting member 2, a support block 31 is fixedly connected to the second cover 3, and a locking block 32 is connected to the support block 31. The connecting member 2 has a locking groove 25 and a through groove 26. The support block 31 and the locking block 32 are slidably connected in the locking groove 25. When the second cover 3 slides to the first position and the second cover 3 rotates relative to the connecting member 2, the support block 31 and the locking block 32 slide out along the through groove 26.

[0041] By making the width of the locking block 32 greater than the width of the support block 31, the locking block 32 is limited by the locking groove 25 when it has not slid to the through groove 26, and can only slide along the locking groove 25, thus preventing the locking block 32 from disengaging from the locking groove 25.

[0042] Regarding the self-locking mechanism of the second cover 3, a first connecting groove is provided on the support block 31. The first connecting groove is slidably connected to the locking block 32. A first spring is connected inside the first connecting groove. The two ends of the first spring are fixedly connected to the two locking blocks 32. A first limiting groove is provided in the locking groove 25. When the locking block 32 slides into the first limiting groove, the elastic force of the first spring is released, and the locking block 32 engages with the first limiting groove, so that the second cover 3 self-locks and prevents the second cover 3 from being opened accidentally.

[0043] Preferably, the first limiting groove is located at the end of the slot 25 away from the through slot 26.

[0044] Regarding the rotation method of the first cover 1, a second connecting rod 11 is fixedly connected to the first cover 1, and a rotating groove 22 is opened on the connecting piece 2, and the second connecting rod 11 is rotatably connected to the rotating groove 22.

[0045] Regarding the self-locking mechanism of the first cover 1, the first cover 1 is provided with a second connecting groove, a second limiting block 12 is slidably connected to the second connecting groove, a second spring is fixedly connected inside the second connecting groove, and the end of the second spring away from the second connecting groove is fixedly connected to the second limiting block 12. The connecting piece 2 is provided with a second limiting groove 21. When the second limiting block 12 slides into the second limiting groove 21, the elastic force of the second spring is released, and the second limiting block 12 and the second limiting groove 21 are engaged.

[0046] A connecting part 4 is fixedly connected to the connector 2, and the connector 4 is connected to the vehicle frame.

[0047] When inspecting the middle of the chain, first pull the first cover 1 to separate the second limit block 12 from the second limit groove 21, thereby unlocking the first cover 1. Then rotate the first cover 1 around the second connecting rod 11 to expose the chain in the chainring area.

[0048] When inspecting the end of the chain, push the second cover 3 along the groove 25 to slide away from the first cover 1, so that the locking block 32 disengages from the first limiting groove until it slides to the first position. At this time, the second connecting block 33 connects to the first rotating rod 24 through the opening 35 with the through hole 34 on it. Rotate the second cover 3 with the first rotating rod 24 as the axis to expose the end of the chain.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
