CROSS REFERENCE TO RELATED APPLICATION

This application claims priority benefit of Chinese patent Application No. 202420216307.4, filed on Jan. 29, 2024, and the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to the technical field of headlamp holders, and more particularly relates to connection arrangement for a power supply and a power wire of a split type headlamp.

BACKGROUND

At present, the structure of a split type headlamp on the market includes three major parts: a headlamp, a power wire, and a power supply. In order to ensure the endurance performance, such headlamp is generally equipped with a high-power power supply, which may be fixed or replaceable. The fixed power supply is non-replaceable, has a larger volume, and is heavier, so a trade-off needs to be consider in terms of headlamp performance and wearing experience. The replaceable power supply requires a larger installation and locking structure, which is connected to the power wire by means of contacts, thus being larger in volume, heavier, and poor in waterproof effect. Therefore, how to guarantee energy supply while minimizing the head load under the condition of reducing the weight of the structure has become a technical difficulty that the split type headlamp needs to overcome urgently.

SUMMARY

The technical problem to be solved by the present disclosure is to provide connection arrangement for a power supply and a power wire of a split type headlamp in view of the above-mentioned shortcomings.

In order to solve the above technical problems, the present disclosure adopts the following technical solutions:

Connection arrangement for a power supply and a power wire of a split type headlamp includes a headlamp, a headlamp band, the power supply, the power wire, and a fixed holder, where the headlamp and the fixed holder are both disposed on the headlamp band,

• • the power supply is provided with a power supply port and a clamping slot, the power supply is detachably disposed on the fixed holder,
  • the fixed holder is provided with a through hole,
  • a first end of the power wire is connected to the headlamp, a second end of the power wire can be in a detachable connection with the power supply port after passing through the through hole, an elastic buckle is disposed at an outer side of the second end of the power wire, and the elastic buckle can cross the fixed holder and then snap into the clamping slot.

Further, the fixed holder includes a base and a fixed frame, the base is disposed on the headlamp band, the fixed frame is disposed on the base, the power supply is detachably disposed inside the fixed frame, and the through hole is reserved in the fixed frame.

Further, elastic clamping portions are provided on both sides of a middle part of the base, and the elastic clamping portions are configured to fix a battery in the fixed frame.

Further, the fixed frame includes a first half frame and a second half frame, and the first half frame and the second half frame are disposed on the elastic clamping portions.

Further, a power supply port fixing position is provided on the first half frame, and the through hole is reserved in a middle part of the power supply port fixing position.

Further, a first hollow hole is formed in the elastic clamping portions, and a plurality of connecting rods are disposed inside the first hollow hole; and outer frames of the elastic clamping portions and the connecting rods form a plurality of triangular-like frame structures.

Further, the outer frames of the elastic clamping portions are in triangular-like shapes.

Further, the base is provided with a plurality of second hollow holes.

Further, two connecting buckles are disposed on an outer side of the base, and the connecting buckles are configured to achieve a connection with the headlamp band.

Further, a mounting groove is formed at the outer side of the second end of the power wire, the elastic buckle is disposed on a fixing sleeve, and the fixing sleeve is matched with the mounting groove.

After adopting the above technical solutions, the present disclosure has the following advantages compared with the prior art:

The present disclosure mainly uses the elastic buckle and clamping slot to fix the power wire, power supply and fixed holder together, and locks the connection relationship thereof through the elastic buckle and clamping slot, which not only maintains a stable connection between the power wire and the power supply to keep power flowing, but also prevents battery displacement and deformation within the fixed holder; and furthermore, the number of components is reduced while ensuring stability, achieving a lightweight structure.

Due to the arrangement f the fixed holder of the present disclosure, the volume of the present disclosure is minimized through a hollow-carved design while ensuring rigidity, thus realizing light weight, and reducing the head load of a wearer.

The end of the power wire connected to the power supply port is locked by means of the elastic buckle, the clamping slot, and the power supply port fixing position, which is more stable than the common contact power supply method on the market and facilitates waterproof treatment, effectively ensuring the working stability of the connecting devices.

The present disclosure will be described in detail below with reference to the accompanying drawings and embodiments.
