Detailed Implementation

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] This application discloses a flashlight with a heat insulation structure, such as... Figure 1 and Figure 2 As shown, it includes: a flashlight body, a mounting base 110, a housing assembly, and a heat insulation assembly; the flashlight body includes a lamp holder 111 and a control board 112; the mounting base 110 is embedded in the flashlight body; the housing assembly is hollow, forming an installation cavity; the installation cavity is used to support the flashlight body; the housing assembly is provided with a plurality of first heat dissipation openings 221; the plurality of first heat dissipation openings 221 communicate with the installation cavity; the plurality of first heat dissipation openings 221 are used to dissipate heat in the installation cavity; the heat insulation assembly is located between the mounting base 110 and the housing assembly, and the heat insulation assembly is composed of heat insulation material.

[0023] In this embodiment, a heat insulation component is disposed between the fixing base 110 and the housing assembly to lift the housing assembly upwards, thereby forming a heat insulation gap between the housing assembly and the fixing base 110. When the flashlight is working, this prevents the heat generated by the lamp holder 111 and the control board 112 from being directly conducted to the housing assembly. Simultaneously, a first heat dissipation opening 221 is provided on the housing assembly to dissipate the heat generated by the lamp holder 111 and the control board 112 to the outside, effectively preventing the temperature of the flashlight grip area from rising. In this embodiment, the heat insulation component uses a silicone gasket, a ceramic fiber gasket, or an aerogel felt.

[0024] In one embodiment, the heat insulation component includes a first heat insulation element and a second heat insulation element; wherein the first heat insulation element and the second heat insulation element are disposed on both sides of the fixing base 110 and are both in contact with the housing assembly. Specifically, in actual use, the first heat insulation element and the second heat insulation element are disposed opposite to each other on both sides of the fixing base 110. This arrangement creates a heat insulation gap between both sides of the fixing base 110 and the housing assembly, preventing the heat generated by the lamp holder 111 and the control board 112 from being directly conducted to the housing assembly.

[0025] In this embodiment, the housing assembly includes a first housing and a second housing; wherein the first heat insulation member is fitted to the inner sidewall of the first housing; and the second heat insulation member is fitted to the inner sidewall of the second housing.

[0026] Specifically, the first housing 210 and the second housing 220 cover each other and are arranged opposite each other on both sides of the fixing base 110. One end of the fixing base 110 is provided with a lamp holder 111 and the other end is provided with a control board 112. A first heat insulation member 300 is provided on the end of the fixing base 110 near the lamp holder 111, and the first heat insulation member 300 protrudes from one side surface of the fixing base 110, that is, the first heat insulation member 300 is located between the fixing base 110 and the first housing 210, and one side of the first heat insulation member 300 is in contact with the side surface of the fixing base 110, and the other side is in contact with the inner side wall of the first housing 210; at the same time, the second heat insulation member 400 protrudes from the surface of the fixing base 110 and is in contact with the second housing 220. In this way, the first heat insulation member is located between the first housing and the fixing base, and the second heat insulation member is located between the second housing and the fixing base, so that a heat insulation gap is formed between the fixing base and the first housing and the second housing, preventing the heat generated by the lamp holder and the control board from being directly conducted to the first housing and the second housing, but instead dissipating to the outside through the first heat dissipation opening 221.

[0027] like Figure 3 and Figure 4 As shown, the first housing 210 and the second housing 220 are arranged around both sides of the fixed base 110, and the fixed base 110 and the second housing 220 together form a first cavity 600, and the fixed base 110 and the first housing 210 together form a second cavity 700. One end of the fixed base 110 is provided with a lamp holder 111 and extends toward the second cavity 700, and the other end of the fixed base 110 is provided with a control plate 112 and extends toward the first cavity 600. That is, the lamp holder 111 and the control plate 112 are respectively arranged on the two side walls of the fixed base 110. The second heat insulation component 400 protrudes from the side surface of the fixed base 110 near the control plate 112. That is, the second heat insulation component 400 is located between the fixed base 110 and the second housing 220. One side of the second heat insulation component 400 is in contact with the side surface of the fixed base 110, and the other side is in contact with the inner wall of the second housing 220, so that a heat insulation gap is formed between the second housing 220 and the fixed base 110, so as to prevent the heat generated by the control plate 112 when the flashlight is working from being directly transferred to the second housing 220.

[0028] like Figure 2 and Figure 3As shown, in this embodiment, the first heat insulation member 300 and the second heat insulation member 400 protrude from each other onto the two side surfaces of the fixing base 110, forming gaps between the fixing base 110 and both the first housing 210 and the second housing 220. This isolates the heat conduction between the lamp holder 111 and the first housing 210, as well as between the control board 112 and the second housing 220, preventing the heat generated by the lamp holder 111 and the control board 112 from being directly transferred to the housing assembly 200. In this embodiment, the first housing 210 and the fixing base 110 together form a second cavity 700; the second cavity 700 is used to carry the power supply 800, which is electrically connected to the lamp holder 111. In this embodiment, the control board 112 is electrically connected to the display screen 113 on the flashlight body. During the use of the flashlight, the display screen 113 can display the remaining power or brightness of the flashlight. In this embodiment, the connection method and working principle of the control board 112 and the display screen 113 are existing technologies.

[0029] like Figure 3 As shown, in one embodiment, the second heat insulation member 400 is provided with a plurality of first heat dissipation fins 410; the second housing 220 is provided with first heat dissipation openings 221 corresponding to the positions of the heat dissipation fins; the first heat dissipation fins 410 extend at least partially into the first heat dissipation openings 221. Specifically, in actual use, the second heat insulation component 400 has a plurality of first heat dissipation fins 410 arranged at intervals, and the second housing 220 has a first heat dissipation opening 221 corresponding to the position of the first heat dissipation fins 410. The plurality of first heat dissipation fins 410 extend at least partially into the first heat dissipation opening 221, that is, the plurality of first heat dissipation fins 410 are connected to the outside through the first heat dissipation opening 221. During the operation of the flashlight, the heat generated by the control board 112 is transferred to the fixing base 110, and the first heat dissipation fins 410 conduct the heat on the fixing base 110 to the outside. In this way, by setting the second heat insulation component 400 and the first heat dissipation fins 410, the heat generated during the operation of the flashlight is prevented from being directly transferred to the housing assembly, but is instead dissipated through the first heat dissipation opening 221.

[0030] The second heat insulation component 400 disclosed in this application forms an air insulation layer between the mounting base 110 and the second housing 220, effectively blocking the heat generated by the control board 112 from being transferred to the second housing 220, thereby preventing overheating of the flashlight grip area due to housing temperature rise. Simultaneously, several first heat dissipation fins 410 communicate with the external environment through first heat dissipation openings 221, directly dissipating the heat accumulated on the mounting base 110 to the outside environment through the first heat dissipation openings 221, ensuring efficient heat dissipation and preventing heat accumulation. In this embodiment, at least a portion of the several first heat dissipation fins 410 is in contact with the mounting base 110, ensuring that the first heat dissipation fins 410 effectively dissipate the heat from the mounting base 110.

[0031] like Figure 4 and Figure 5 As shown, in one embodiment of the present invention, the flashlight with heat insulation structure further includes a third heat insulation component 500; the third heat insulation component 500 is located on one side of the fixing base 110 and is in contact with the housing assembly 200; one side of the third heat insulation component 500 extends toward the first cavity 600 to form a first flange 510; one side of the first flange 510 is in contact with the fixing base 110, and the other side is in contact with the inner surface of the second housing 220.

[0032] Specifically, the first housing 210 and the second housing 220 are connected and enclosed together. The third heat insulation member 500 is located at the connection between the first housing 210 and the second housing 220, that is, the third heat insulation member 500 is embedded between the housing assembly 200 and the fixing base 110. One side of the third heat insulation member 500 extends obliquely towards the first cavity 600 to form a first flange 510, and the other side extends towards the second cavity 700. One surface of the first flange 510 is in close contact with the fixing base 110, and the other surface is in close contact with the inner surface of the second housing 220. In actual use, the third heat insulation member 500 creates a heat insulation gap between the first housing 210, the second housing 220 and the fixing base 110, preventing the heat generated by the lamp holder 111 and the control board 112 when the flashlight is working from being directly transferred to the housing assembly 200.

[0033] like Figure 4 As shown, in this embodiment, the first flange 510 is provided with a plurality of second heat dissipation openings 511; the second housing 220 is provided with third heat dissipation openings 222 corresponding to the positions of the second heat dissipation openings 511; the second heat dissipation opening communicates with the third heat dissipation opening. One side surface of the first flange 510 is tightly fitted with the fixing base 110, and the other side surface is tightly fitted with the inner surface of the second housing 220, that is, the first flange 510 is embedded between the fixing base 110 and the second housing 220. The first flange 510 is provided with a plurality of second heat dissipation openings 511, and the second housing 220 is provided with a plurality of third heat dissipation openings 222 corresponding to the positions of the second heat dissipation openings 511. The second heat dissipation opening 511 and the third heat dissipation opening 222 are connected. The mounting base 110 is connected to the outside through the second heat dissipation opening 511 and the third heat dissipation opening 222. When the flashlight is working for a long time, the heat generated by the lamp holder 111 and the control board 112 is conducted to the mounting base 110. The heat of the mounting base 110 is dissipated to the outside through the second heat dissipation opening 511 and the third heat dissipation opening 222 to avoid heat accumulation.

[0034] like Figure 3 and Figure 4As shown, in this embodiment, the mounting base 110 is provided with a plurality of second heat dissipation fins 114 at the position corresponding to the second heat dissipation opening 511; the second heat dissipation fins 114 extend at least partially into the second heat dissipation opening 511. Specifically, in actual use, the mounting base 110 is provided with a plurality of second heat dissipation fins 114 at the position corresponding to the second heat dissipation opening 511, the plurality of second heat dissipation fins 114 are evenly spaced, and at least part of the second heat dissipation fins 114 extend into the second heat dissipation opening 511, that is, the plurality of second heat dissipation fins 114 are connected to the outside through the second heat dissipation opening 511 and the third heat dissipation opening 222. During the operation of the flashlight, the second heat dissipation fins 114 accelerate the heat dissipation from the mounting base 110 to the outside.

[0035] like Figure 4 As shown, in one embodiment, at least two third heat insulation elements 500 are provided; at least two third heat insulation elements 500 are disposed opposite each other on both sides of the fixing base 110. The third heat insulation element 500, the first heat insulation element 300, and the second heat insulation element 400 are all embedded between the fixing base 110 and the housing assembly 200, and the first heat insulation element 300, the second heat insulation element 400, and the third heat insulation element 500 are respectively located on different side surfaces of the fixing base 110, so that the fixing base 110 forms a heat insulation gap with the housing assembly 200 in all directions, effectively preventing the heat generated by the lamp holder 111 and the control board 112 from being directly conducted to the housing assembly 200, thereby avoiding the temperature rise of the flashlight grip position.

[0036] like Figure 5 As shown, in this embodiment, the side surface of the third heat insulation member 500 extends outward to form a second flange 512; the second flange 512 penetrates the housing assembly 200; and the second flange 512 is provided with a plurality of anti-slip protrusions 513. Specifically, the third heat insulation member 500 is disposed at the connection between the first housing 210 and the second housing 220; the third heat insulation member 500 protrudes to form the second flange 512, at least a portion of the second flange 512 protrudes from the first housing 210 and the second housing 220, and the second flange 512 is provided with a plurality of anti-slip protrusions 513. When the user holds the flashlight, the anti-slip protrusions 513 contact the user's fingers, increasing the friction between the flashlight and the fingers, and preventing the flashlight from slipping.

[0037] In one embodiment, two third heat insulation members 500 are provided, respectively disposed on the two side edges of the fixing base 110. The first heat insulation member 300 and the second heat insulation member 400 are disposed on the two side surfaces of the fixing base 110. Simultaneously, the first heat dissipation opening 221 and the third heat dissipation opening 222 are both disposed on the second housing 220, and a plurality of second heat dissipation openings 511 are spaced apart on the side edges of the second housing 220. Therefore, in use, the user can hold the flashlight from the first housing 210 towards the second housing 220, i.e., the first housing 210 faces the user's palm, the thumb grips the anti-slip protrusion 513, and the second housing 220 with the first heat dissipation opening 221 and the third heat dissipation opening 222 faces outwards, thus ensuring a stable grip while ensuring unobstructed airflow for heat dissipation.

[0038] In summary, this utility model discloses a flashlight with a heat insulation structure, comprising: a flashlight body, a mounting base, a shell assembly, and a heat insulation component; the flashlight body includes a lamp holder and a control board; the mounting base is embedded in the flashlight body; the shell assembly is hollow, forming an installation cavity; the installation cavity is used to support the flashlight body; the shell assembly has a plurality of first heat dissipation openings; the plurality of first heat dissipation openings communicate with the installation cavity; the plurality of first heat dissipation openings are used to dissipate heat from the installation cavity; the heat insulation component is located between the mounting base and the shell assembly, and the heat insulation component is composed of heat insulation material. This application places the heat insulation component between the mounting base and the shell assembly to lift the shell assembly upwards, thereby forming a heat insulation gap between the shell assembly and the mounting base. Simultaneously, the first heat dissipation openings on the shell assembly allow more heat generated by the lamp holder and control board to dissipate outwards through the first heat dissipation openings during flashlight operation, rather than being directly transferred to the surface of the shell assembly, effectively avoiding the problem of temperature rise at the flashlight grip area.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0040] It should be noted that this utility model uses a flashlight with a heat insulation structure as an example to introduce the specific structure and working principle of this utility model, but the application of this utility model is not limited to flashlights with heat insulation structures, and can also be applied to the production and use of other similar workpieces.
