Abstract
Description
Technical Field
[0001] This utility model relates to the field of wireless communication and lighting equipment technology, specifically to a wireless remote control antenna device suitable for metal-cased mobile lighting products. Background Technology
[0002] With the upgrading of consumer demand, all-metal casings have become the first choice for portable lighting products (such as high-end flashlights and searchlights) due to their excellent thermal conductivity, wear resistance, and high-end texture. At the same time, to improve ease of operation, wireless remote control functions are widely integrated into this type of product.
[0003] However, metal casings have a strong shielding effect on electromagnetic waves, leading to severe signal attenuation of the built-in antenna, resulting in short remote control distance, low sensitivity, and even malfunction. Using an external antenna compromises the product's aesthetic integrity and structural sealing, and the antenna is also susceptible to impact damage. Existing technologies that attempt to integrate the antenna into the metal casing lack effective insulation and sealing design, making it difficult to simultaneously guarantee stable signal reception and product reliability in complex environments (such as outdoor, humid, and dusty conditions).
[0004] Therefore, there is an urgent need for an innovative antenna device that can achieve stable and sensitive wireless remote control functionality on mobile lighting products with all-metal casings, without sacrificing their waterproof performance and structural strength. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a wireless remote control antenna device for metal-cased portable lighting products. This device effectively solves the problem of antenna signal shielding by the metal casing through ingenious insulation and integrated sealing design, while ensuring the product's waterproof rating and structural stability.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A wireless remote control antenna device for a metal-cased portable lighting product includes a lamp holder, an insulating ring, an FPC antenna, a protective ring, a first O-ring, and a second O-ring. The lamp holder is made of metal, with a groove and a through hole for threading wires on its annular outer wall. The insulating ring is fitted and fixed within the groove. The FPC antenna is fixedly attached to the outer circumference of the insulating ring to insulate it from the metal lamp holder. The protective ring is fitted over the insulating ring and the FPC antenna. The front end of the lamp holder is detachably connected to a lamp head assembly. The first and second O-rings prevent water from entering through the through hole in the groove. The rear end of the lamp holder is detachably connected to a metal cylindrical body assembly. The FPC antenna is electrically connected to a PCB assembly located inside the lamp holder via a wire passing through the through hole.
[0008] Furthermore, the insulating ring is made of silicone, EVA, rubber, or polytetrafluoroethylene.
[0009] Furthermore, the protective ring is made of plastic, ceramic, fiberglass, or wood composite materials.
[0010] Furthermore, the first O-ring (5) and the second O-ring (6) are made of silicone rubber.
[0011] Furthermore, the FPC antenna can be replaced with a coil antenna, a metal wire antenna, or a flexible metal sheet antenna.
[0012] Furthermore, the connection between the lamp head assembly and the lamp holder, and between the lamp holder and the cylinder assembly, is a threaded connection, a snap-fit connection, or a magnetic connection.
[0013] Furthermore, the FPC antenna is attached to the insulating ring with adhesive backing, and the wire is electrically connected to the conductive part of the FPC antenna through solder joints.
[0014] Furthermore, the insulating ring is fixed in the groove by an interference fit.
[0015] Furthermore, the protective ring abuts against the inner wall of the lamp head assembly.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. Effectively solves signal shielding: By attaching the FPC antenna to the insulating ring, it is completely isolated from the metal lamp holder and the cylinder body, breaking the electromagnetic shielding cavity formed by the metal shell, which greatly improves the receiving distance and stability of the wireless remote control signal.
[0018] 2. High-level sealing protection: The first and second O-rings form a double sealing barrier at both ends of the groove. Combined with the detachable connection structure, the entire device can easily achieve a high waterproof rating of IPX8 and adapt to harsh environments.
[0019] 3. Robust and durable structure: The protective ring provides reliable physical protection for the internal FPC antenna and insulating ring, preventing damage during assembly, use, or impact, thus extending the product's service life.
[0020] 4. High versatility and flexibility: Antenna type, insulation and protective materials can all be replaced according to specific product requirements. This integrated modular design can be flexibly adapted to all-metal mobile lighting products of different sizes and uses. Attached Figure Description

[0027] 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.
[0028] like Figures 1 to 4As shown, this utility model provides a wireless remote control antenna device for a metal-cased mobile lighting product, mainly applied to mobile lighting products composed of a metal cylindrical component 9. Its core lies in an integrated, layered structure. The module uses a metal lamp holder 7 as a carrier, with a groove 701 and a through hole 702 machined on the annular outer wall of the lamp holder 7.
[0029] During assembly, an insulating ring 4 made of silicone is first pressed into and fixed in the groove 701 using an interference fit. Then, the FPC antenna 3 is smoothly attached to the outer circumference of the insulating ring 4 using the adhesive 303 on its back. This design completely isolates the FPC antenna 3 from the metal lamp holder 7 both physically and electrically, forming the core of solving the signal shielding problem.
[0030] Next, a plastic protective ring 2 is fitted over the insulating ring 4 and the FPC antenna 3. This protective ring 2 not only provides protection, but its end also abuts against the inner wall of the lamp holder assembly 1, which helps in the positioning and stability of the entire antenna module. The first O-ring 5 and the second O-ring 6 are made of silicone rubber and are located on both sides of the insulating ring 4 along the axial direction, respectively. They are interference-fitted into the gap between the lamp holder 7 and the protective ring 2 to achieve IPX8 waterproof rating.
[0031] The FPC antenna 3 is connected to the PCB assembly 8 via a wire 302 that passes through a through-hole 702. Solder joints 301 ensure the reliability of the electrical connection. The PCB assembly 8 receives and processes the wireless signals from the FPC antenna 3 to control the lighting fixture.
[0032] Finally, the lamp holder assembly 1 is screwed onto the front end of the lamp holder 7 using a threaded connection; similarly, the metal body assembly 9 is screwed onto the rear end of the lamp holder 7. The double O-ring structure ensures the overall high waterproof performance of the product.
[0033] Working principle: When the user operates the wireless remote control, the control signal electromagnetic waves penetrate the plastic protective ring 2 and are effectively received by the FPC antenna 3. The received electrical signal is transmitted to the control circuit on the PCB assembly 8 through the wire 302. After decoding, it controls the LED light source of the lamp head assembly 1 to achieve functions such as switching, dimming, and strobe. Because the FPC antenna 3 achieves reliable insulation isolation from all metal parts through the silicone insulating ring 4, the signal reception sensitivity is high and the operation is stable.
[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
