Description

Technical Field

[0001] The utility model belongs to the technical field of bicycle lamps, and in particular relates to a bicycle lamp with a replaceable lithium battery. Background Art

[0002] Most traditional bicycles lack lighting devices. When riding at night, the line of sight is obstructed and visibility is low, posing a safety hazard. As people's safety awareness increases, bicycles are now generally equipped with headlights, which are lamps installed on bicycles for night lighting.

[0003] Since the overall structure of bicycles is simple and the headlights are generally small in size, most of them use rechargeable lithium battery headlights. The outer shell of such headlights cannot be opened. When the battery is out of power, the internal battery is charged through a charging cable. The headlights are easily damaged due to long-term exposure to the external environment. After damage, since the headlights cannot be turned on, most of them are directly discarded. Since the headlights contain lithium batteries, there are great safety hazards; and if the internal battery is damaged, it is not easy to replace. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5The utility model provides a lithium battery detachable bicycle lamp, comprising a lamp body 1, the lamp body 1 comprising an upper shell 2 and a lower shell 3, a battery is arranged inside the lamp body 1, the lamp body 1 is connected with a control line 4, and then the lamp is controlled by connecting an external control button through the control line 4, the upper and lower shells of the lamp body 1 are openable structures, and the battery can be detached and replaced after opening, and the lithium battery can be taken out for replacement. When the lamp is completely damaged, the lithium battery can also be removed and discarded in a classified manner to improve safety; the upper shell 2 and the lower shell 3 are connected by a mutual bite structure that runs through the left and right ends horizontally, and the side limit is performed while being connected. The upper shell 2 is provided with a first fixing groove 5 at the connection part, and a compression spring 6 and a fixing block 7 are installed in the first fixing groove 5; the lower shell 3 is provided with a second fixing groove 8 corresponding to the first fixing groove 5; the fixing block 7 is partially pushed into the second fixing groove 8 by the compression action of the compression spring 6; the lower shell 3 is provided with a through hole 9 which passes through the second fixing groove 8; the upper and lower shells are locked by the fixing block 7 being clamped between the first fixing groove 5 and the second fixing groove 8, which is very stable and has high sealing performance. At the same time, by pushing the fixing block 7 back into the first fixing groove 5, the upper shell 2 and the lower shell 3 can be opened, so that the lithium battery can be easily replaced.

[0021] Specifically, the first fixing groove 5, the extrusion spring 6, the fixing block 7 and the second fixing groove 8 are provided at least in two places and are distributed at the left and right ends of the lamp body 1; in this embodiment, the two ends of the lamp body 1 are locked, and the overall stability is high.

[0022] Specifically, the lamp body 1 is provided with an annular groove 10 along the longitudinal section corresponding to the through hole 9, and a sealing ring 11 is sleeved in the annular groove 10; in this embodiment, external debris is prevented from entering the through hole 9 to affect the sealing and safety.

[0023] Specifically, the sealing ring 11 is a disconnected structure and is elastic. Under the action of its own elasticity, the disconnected part is tightly closed when it is sleeved in the annular groove 10. In this embodiment, the sealing ring 11 is easy to install and remove, and at the same time, it plays a sealing role when sleeved in the annular groove 10.
