[0024] In the first aspect, combining Figures 1 to 10 As shown, this disclosure provides a tail cover 1 assembly for a cycling headlight, which includes a tail cover 1 and a sealing gasket 3.

[0025] Combination Figure 1 and Figure 2 As shown, the tail cover 1 is adapted to the housing 2 of the riding headlight. The housing 2 is a cylindrical structure with openings at both the front and rear ends. The interior of the housing 2 forms a receiving cavity for placing the battery assembly and the light panel assembly, etc.

[0026] Tail cap 1 is fitted onto the rear opening of housing 2, in conjunction with... Figure 3 , Figure 4 and Figure 5 As shown, mounting holes 131 and threaded holes 211 are formed at corresponding positions of the tail cap 1 and the housing 2, respectively. Fasteners pass through the mounting holes 131 and are threadedly connected to the threaded holes 211 to fix the tail cap 1 to the housing 2.

[0027] The sealing gasket 3 is arranged in a ring structure between the housing 2 and the tail cap 1. A through hole is formed on the sealing gasket 3 at a position corresponding to the threaded hole 211 so that fasteners can pass through. The sealing gasket 3 is configured to seal the gap between the housing 2 and the tail cap 1.

[0028] Among them, combined Figure 7 As shown, the tail cover 1 includes a bottom wall 11 and a side wall 12. At the connection between the bottom wall 11 and the side wall 12, a plurality of mounting posts 13 are formed on the side facing the housing 2. There are four mounting posts 13, which are distributed at the corners of the tail cover 1. Mounting holes 131 are formed on the mounting posts 13. A plurality of concentric annular ribs 14 are formed on the bottom wall 11 of the tail cover 1 on the side facing the housing 2. The annular ribs 14 are located in the middle of the tail cover 1. The annular ribs 14 are connected to each mounting post 13 by a first reinforcing rib 15.

[0029] Specifically, the tail cover 1 assembly for the cycling headlight includes a tail cover 1 and a sealing gasket 3. The connection between the bottom wall 11 and the side wall 12 of the tail cover 1 has a mounting post 13 formed on the side facing the housing 2. The mounting post 13 has a mounting hole 131. The inner wall surface of the housing 2 has a support strip 21. There are four sets of support strips 21. The four sets of support strips 21 are used to limit the position of the battery assembly of the cycling headlight in the housing 2. The support strips 21 have threaded holes 211 to provide a fixing position for the installation of the battery assembly, etc.

[0030] During assembly, fasteners pass through mounting hole 131 and threaded into threaded hole 211 to fix tail cover 1 to housing 2, making it easy to remove tail cover 1; by setting sealing gasket 3 between housing 2 and tail cover 1, the sealing and waterproofing effect can be improved.

[0031] Specifically, mounting hole 131 can be either a threaded hole or a through hole.

[0032] An annular rib 14 is formed on the bottom wall 11 of the tail cover 1 on the side facing the housing 2. The annular rib 14 is located in the middle of the tail cover 1. The annular rib 14 is connected to each mounting post 13 by a first reinforcing rib 15. The annular rib 14 and the first reinforcing rib 15 can increase the rigidity of the tail cover 1 and reduce the risk of deformation of the tail cover 1. While maintaining the structural strength, it can also reduce the use of materials, which is conducive to reducing costs.

[0033] Specifically, the first reinforcing rib 15 extends between two adjacent concentric ring ribs 14.

[0034] Specifically, the annular rib 14 is circular. Of course, the shape and number of the annular rib 14 can also be set according to actual needs.

[0035] In some embodiments of this application, the annular rib 14 is connected to the side wall 12 of the tail cap 1 by a second reinforcing rib 16, and two adjacent mounting posts 13 are connected by a third reinforcing rib 17, with the third reinforcing rib 17 and the second reinforcing rib 16 arranged crosswise.

[0036] Specifically, by setting a second reinforcing rib 16 and a third reinforcing rib 17, the third reinforcing rib 17 and the second reinforcing rib 16 are arranged in a grid-like structure, which helps to disperse stress and improve the overall strength and resistance to deformation.

[0037] In some embodiments of this application, the fastener is provided with a waterproof adhesive, which is configured to seal the gap between the fastener and the mounting hole 131 and the threaded hole 211.

[0038] Specifically, applying waterproof adhesive to the fasteners helps ensure the waterproof performance of the mounting hole 131 and the threaded hole 211.

[0039] In some embodiments of this application, the bottom wall 11 has a first recess 111 on the side away from the housing 2, and a charging port 1111 for charging the charging interface component 5 inside the riding headlight is formed on the first recess 111. The charging port 1111 corresponds to the plug port of the charging interface component 5. The charging interface component 5 is a USB interface component or a type-c interface component. The tail cover 1 assembly for the riding headlight also includes a dust plug 4.

[0040] The dust plug 4 is at least partially engaged with the first recess 111, and the dust plug 4 is detachably connected to the tail cap 1. The dust plug 4 is configured to block the charging port 1111, further ensuring the sealing and waterproof effect.

[0041] Specifically, the outer surface of the dust plug 4 is marked with a charging symbol.

[0042] In some embodiments of this application, the edge of the charging port 1111 is formed with a circumferential edge ring 112 on the side facing the dust plug 4, and a pre-installed part 41 is formed on the dust plug 4 facing the tail cover 1, the pre-installed part 41 being adapted to the edge ring 112.

[0043] Specifically, during assembly, when the dust plug 4 is engaged with the first recess 111, the corresponding pre-installed part 41 is inserted into the edge ring 112. This can improve the connection strength between the dust plug 4 and the tail cap 1, and also improve the waterproof effect.

[0044] In some embodiments of this application, combined with Figure 6 As shown, a mounting opening 1112 is formed on one side of the edge ring 112 on the first recess 111. A connecting portion 42 is formed on the dust plug 4 at a position corresponding to the mounting opening 1112. The connecting portion 42 passes through the mounting opening 1112 and is configured to prevent the dust plug 4 from detaching from the tail cap 1.

[0045] Specifically, when a user needs to charge the cycling headlight, they can open the dust plug 4 and flip it to one side to expose the charging port 1111, making it easy for the user to connect the charging cable to the charging interface component 5 for charging. At the same time, under the action of the connecting part 42, the dust plug 4 will not detach from the tail cover 1, preventing the dust plug 4 from being lost.

[0046] In some embodiments of this application, combined with Figure 8 , Figure 9 and Figure 10 As shown, the part of the dust plug 4 inserted into the tail cap 1 is interference-fitted with the tail cap 1, which can achieve a sealing and waterproof effect.

[0047] Specifically, the connection part 42 and the mounting port 1112, as well as the dust plug 4 and the first recessed part 111, are both interference fits.

[0048] Specifically, a protrusion 421 is formed on the connecting part 42. The size of the protrusion 421 is larger than the size of the mounting opening 1112. The protrusion 421 abuts against the tail cap 1. When the user opens the dust plug 4, the protrusion 421 prevents the connecting part 42 from coming out of the mounting opening 1112.

[0049] In some embodiments of this application, combined with Figure 6 As shown, the tail cap 1 has a second recess 113 formed on the side away from the housing 2. The second recess 113 is located on one side of the first recess 111, and the depth of the second recess 113 is shallower than that of the first recess 111. The dust plug 4 extends outward from one side to form an extension 43, which is adapted to the second recess 113.

[0050] Specifically, by providing a second recess 113, which is located on one side of the first recess 111, and the depth of the second recess 113 is shallower than that of the first recess 111, the second recess 113 is prevented from affecting the sealing effect between the dust plug 4 and the first recess 111. An extension 43 is formed on one side of the dust plug 4, which makes it easy for the user to open the dust plug 4 by bending the extension 43.

[0051] In some embodiments of this application, a notch 431 is formed on the extension 43 toward the side of the second recess 113, so that the user can insert his / her finger into the notch 431 to pry open the extension 43 and thus open the dust plug 4.

[0052] In some embodiments of this application, the connection between the bottom wall 11 and the side wall 12 is formed with a rounded chamfer on the side away from the housing 2 to avoid the formation of dead corners at the connection between the bottom wall 11 and the side wall 12. This allows water to drain quickly after water is sprayed onto the tail cap 1, preventing water accumulation.

[0053] In some embodiments of this application, the tail cap 1 is provided with a hanging hole 18. Users can attach a rope through the hanging hole 18, which adds an extra layer of safety to the structure to prevent the riding headlight from falling off, thereby improving safety, aesthetics, and installation flexibility of the riding headlight.
