Description

Technical Field

[0001] This utility model relates to the field of bicycle accessories technology, and in particular to a bicycle headlight with an improved heat dissipation structure. Background Technology

[0002] In the field of bicycle component technology, the bicycle headlight is an important safety component for riding at night or in low light conditions, and its performance stability is particularly crucial.

[0003] However, traditional bicycle headlights have several problems: First, most traditional headlights rely solely on the outer casing for simple heat dissipation, lacking a systematic heat dissipation design. This makes it difficult to quickly dissipate the large amount of heat generated during operation, significantly shortening the lifespan of the headlight assembly and potentially causing malfunctions due to overheating. Second, traditional integrated bicycle headlights combine the headlight body with the battery, resulting in a cramped internal space. This not only increases the overall weight and size but also exacerbates the heat dissipation problem. The battery also generates heat during operation, which, combined with the heat from the LED headlight assembly, leads to even lower heat dissipation efficiency and affects the overall stability of the headlight.

[0004] To address this, we designed a bicycle headlight with an improved heat dissipation structure. Utility Model Content

[0005] This utility model discloses a bicycle headlight with an improved heat dissipation structure. To achieve the above objective, this utility model adopts the following technical solution:

[0006] A bicycle headlight with an improved heat dissipation structure includes a headlight assembly and a power supply assembly. The headlight assembly and the power supply assembly are connected by a power line. The headlight assembly includes a support base block. A cylindrical outer shell is fixedly disposed on the upper surface of the support base block. An LED light group is fixedly disposed inside the cylindrical outer shell.

[0007] The surface of the cylindrical shell is provided with a heat dissipation mechanism, which includes several aluminum alloy heat-conducting strips fixedly connected to the surface of the cylindrical shell, and a conical heat dissipation shroud fixedly connected to the tail end of the cylindrical shell. The surface of the conical heat dissipation shroud is provided with several heat exhaust holes, the front end of the cylindrical shell is provided with several air inlets, and the interior of the cylindrical shell is provided with an annular heat dissipation channel.

[0008] In a preferred embodiment, the annular heat dissipation channel is located between the LED light assembly and the inner wall of the cylindrical housing, and the annular heat dissipation channel surrounds the outer side of the LED light assembly, with the position of the annular heat dissipation channel corresponding to the air inlet.

[0009] In a preferred embodiment, a plurality of air inlets are evenly distributed in a circular array at the front end of the cylindrical shell, and a dust filter is fixedly provided on the inner wall of the air inlets.

[0010] In a preferred embodiment, a plurality of aluminum alloy heat-conducting strips are evenly and symmetrically distributed on both sides of the cylindrical shell, and a heat-conducting air groove is formed between two adjacent aluminum alloy heat-conducting strips.

[0011] In a preferred embodiment, a protective top cover is fixedly provided at the top of the cylindrical outer shell, and an arc-shaped groove is provided on the lower surface of the supporting base block. The size of the arc-shaped groove matches the handlebars of a bicycle, and an anti-slip pad is fixedly provided on the inner wall of the arc-shaped groove.

[0012] In a preferred embodiment, an extension block is fixedly provided on the surface of the support base block, a limiting protrusion is fixedly connected to the upper surface of the extension block, and a rubber strap is fixedly connected to the bottom of the support base block, with a limiting hole matching the limiting protrusion on the surface of the rubber strap.

[0013] In a preferred embodiment, the power supply component includes a battery protection box, inside which a storage battery is placed, and several heat dissipation holes are provided on both sides of the battery protection box.

[0014] In a preferred embodiment, two locking straps are fixedly provided on the lower surface of the battery protection box, and the surfaces of the two locking straps are provided with matching Velcro straps.

[0015] As can be seen from the above, the bicycle headlight with an improved heat dissipation structure provided by this utility model has the following technical effects.

[0016] 1. Through the synergistic effect of multiple heat dissipation structures, the heat generated by the LED light assembly during operation is effectively dissipated. The aluminum alloy heat-conducting strips can quickly conduct heat from the cylindrical outer shell to the air. The heat-conducting air grooves formed by adjacent heat-conducting strips can accelerate air circulation and enhance heat dissipation. The heat exhaust holes on the surface of the conical heat sink cooperate with the air intake holes at the front end of the cylindrical outer shell, combined with the internal annular heat dissipation channel, to form a rapid heat dissipation airflow both inside and outside the headlight housing. This allows cool air to enter from the air intake holes, absorb heat through the annular heat dissipation channel, and then be discharged from the heat exhaust holes. Compared with traditional external heat dissipation, this significantly improves heat dissipation efficiency, ensures stable operation of the LED light assembly, and extends its service life.

[0017] 2. The design adopts a separate structure for the headlight body and battery, effectively saving internal space and solving the problems of large overall weight, poor heat dissipation, and instability associated with traditional integrated headlight structures. Simultaneously, the headlight is securely and easily installed. The arc-shaped groove on the lower surface of the support block matches the bicycle handlebars, and the anti-slip rubber pads on the inner wall increase friction. The limiting holes on the rubber strap surface cooperate with the limiting protrusions on the extension block to firmly fix the support block to the bicycle handlebars. The battery protection box of the power supply component is stably fixed with a locking strap featuring Velcro, making installation simple and convenient. 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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1-5 A bicycle headlight with an improved heat dissipation structure includes a headlight assembly 1 and a power supply assembly 2. The headlight assembly 1 and the power supply assembly 2 are connected by a power line 4 to ensure that the power supply assembly 2 can provide a stable power supply to the headlight assembly 1.

[0029] The vehicle light assembly 1 includes a support base 101. A cylindrical housing 102 is fixedly mounted on the upper surface of the support base 101. The cylindrical housing 102 provides space for the installation and protection of the LED light assembly 103. The LED light assembly 103 is fixedly mounted inside the housing. The LED light assembly 103 is the core component for realizing the lighting function.

[0030] The surface of the cylindrical housing 102 is provided with a heat dissipation mechanism 3, which plays a key role in the heat dissipation process of the entire vehicle light. It includes several aluminum alloy heat-conducting strips 301 fixedly connected to the surface of the cylindrical housing 102, and a conical heat dissipation shroud 302 fixedly connected to the tail end of the cylindrical housing 102. Aluminum alloy has good thermal conductivity.

[0031] The aluminum alloy heat-conducting strip 301 can quickly conduct heat from the cylindrical outer shell 102 to the air, thereby accelerating heat dissipation. The surface of the conical heat sink 302 is provided with several heat dissipation holes 303, which provide channels for the internal hot air to escape, facilitating the release of internal heat. Several air inlets 304 are provided at the front end of the cylindrical outer shell 102, allowing external cold air to enter. An annular heat dissipation channel 305 is provided inside the cylindrical outer shell 102, located between the LED light assembly 103 and the inner wall of the cylindrical outer shell 102, and surrounding the outer side of the LED light assembly 103. The position of the annular heat dissipation channel 305 corresponds to the air inlets 304. This structure allows cold air to enter through the air inlet 304 and flow through the annular heat dissipation channel 305 around the LED light assembly 103, fully absorbing heat before being discharged through the heat exhaust hole 303, forming good air convection, significantly improving heat dissipation efficiency, ensuring stable operation of the LED light assembly 103, and extending its service life.

[0032] Several air inlets 304 are evenly distributed in a circular array at the front end of the cylindrical shell 102. This distribution allows cold air to enter the annular heat dissipation channel 305 more evenly. A dust filter 306 is fixedly installed on the inner wall of the air inlets 304. The dust filter 306 can effectively block dust and other impurities from entering the interior of the cylindrical shell 102, and prevent dust from adhering to the LED light group 103 or other components, thus affecting their performance and heat dissipation effect.

[0033] Several aluminum alloy heat-conducting strips 301 are evenly and symmetrically distributed on both sides of the cylindrical outer shell 102, and a heat-conducting air groove 307 is formed between two adjacent aluminum alloy heat-conducting strips 301. The even and symmetrical distribution allows heat to be evenly dissipated from different positions of the cylindrical outer shell 102, while the heat-conducting air groove 307 can accelerate air circulation, further enhance the heat dissipation effect, and allow heat to be dissipated into the surrounding environment more quickly.

[0034] A protective top cover 104 is fixedly installed at the top of the cylindrical outer shell 102. The protective top cover 104 can provide a certain degree of protection for the internal LED light assembly 103, reducing damage caused by external impacts, rain, etc. The lower surface of the support base 101 has an arc-shaped groove 105. The size of the arc-shaped groove 105 matches the bicycle handlebar, and the inner wall of the arc-shaped groove 105 is fixedly provided with an anti-slip pad. The matching design of the arc-shaped groove 105 and the bicycle handlebar facilitates the installation and positioning of the light on the bicycle handlebar, while the anti-slip pad increases friction, prevents the light from sliding during use, and ensures the stability of the installation.

[0035] An extension block 106 is fixedly provided on the surface of the support base 101. A limiting protrusion 107 is fixedly connected to the upper surface of the extension block 106, and a rubber strap 108 is fixedly connected to the bottom of the support base 101. The surface of the rubber strap 108 has a limiting hole 109 that matches the limiting protrusion 107. When installing the bicycle light assembly 1, the rubber strap 108 is wrapped around the bicycle handlebars, and then the limiting hole 109 is fitted onto the limiting protrusion 107, which can firmly fix the support base 101 to the bicycle handlebars. The operation is simple and convenient, and the fixing effect is good, which can effectively prevent the bicycle light from loosening during riding.

[0036] The power supply component 2 includes a battery protection box 201, which houses a battery that provides power to the entire vehicle headlight. Several heat dissipation holes 202 are provided on both sides of the battery protection box 201. These holes help dissipate heat generated by the battery during operation, preventing overheating from affecting the battery's lifespan and power supply stability.

[0037] Two locking straps 203 are fixedly installed on the lower surface of the battery protection box 201, and each of the two locking straps 203 has matching Velcro straps on its surface. When installing the power supply component 2, the battery protection box 201 can be stably fixed by wrapping the two locking straps 203 around the appropriate position of the bicycle and using the adhesive effect of the Velcro straps. The installation operation is simple and the fixation is firm, which can withstand the bumps during the ride.

[0038] Working principle: In use, first, the light assembly 1 is engaged with the bicycle handlebars through the arc-shaped groove 105 on the lower surface of the support base 101. The anti-slip rubber pad on the inner wall of the arc-shaped groove 105 is used for initial fixation. Then, the rubber strap 108 is wrapped around the bicycle handlebars so that the limiting hole 109 and the limiting protrusion 107 are engaged to complete the fixation of the light assembly 1. Next, the power supply assembly 2 is fixed to the appropriate position on the bicycle through the Velcro on the locking strap 203. The connection between the light assembly 1 and the power supply assembly 2 is achieved through the power cable 4, so that the battery supplies power to the LED light assembly 103. The LED light assembly 103 generates heat during operation. A portion of this heat is transferred to the aluminum alloy heat-conducting strips 301 through the cylindrical outer shell 102. The heat-conducting strips 301 dissipate the heat into the air. The heat-conducting air grooves 307 between adjacent heat-conducting strips 301 accelerate airflow and enhance heat dissipation. Simultaneously, external cool air enters through the air inlet 304, is filtered by the dust filter 306, and then enters the annular heat dissipation channel 305. After absorbing heat from around the LED light assembly 103, the hot air is exhausted through the heat dissipation holes 303 on the conical heat sink 302. The heat generated by the battery in the power supply assembly 2 is dissipated through the heat dissipation holes 202 on both sides of the battery protection box 201, ensuring stable power supply.

[0039] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
