DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0019] Please refer to Figure 1-Figure 3 As shown, the first aspect of the present application proposes a shell assembly 10a, which has good sealing performance and can effectively reduce the possibility of water vapor entering the interior of the headlamp and burning electronic components.

[0020] The shell assembly 10a is applied to a lighting lamp head 10, and the shell assembly 10a includes a rear shell 12, a front shell 11 and a sealing member 13. The front shell 11 includes a first shell 111 and a second shell 112. The first shell 111 is connected to the rear shell 12 and is surrounded by the rear shell 12 to form a receiving cavity. The second shell 112 is covered on the outer side of the first shell 111 and is integrally formed with the first shell 111. The sealing member 13 is located in the receiving cavity and is arranged at the edge of the first port 111b of the first shell 111. A portion of the second shell 112 passes through the first shell 111 and is integrally formed with the sealing member 13.

[0021] The following combination Figure 1-Figure 5 The specific structure of the shell component 10a is introduced in detail.

[0022] like Figure 1-Figure 5 As shown, the housing assembly 10 a includes a rear housing 12 , a front housing 11 and a sealing member 13 .

[0023] The rear shell 12 is one shell of the shell assembly 10a. The specific material of the rear shell 12 is not limited here. Designers can make reasonable choices according to actual needs. For example, the material of the rear shell 12 can be but is not limited to plastic, silicone or resin, etc.

[0024] The front shell 11 serves as another shell of the shell assembly 10a. The specific material of the front shell 11 is not limited here, and designers can make reasonable choices based on actual needs. For example, the material of the front shell 11 can be but is not limited to plastic, silicone or resin, etc.

[0025] The front shell 11 includes a first shell 111 and a second shell 112. The first shell 111 is connected to the rear shell 12 and encloses the rear shell 12 to form a receiving cavity. The second shell 112 is covered on the outside of the first shell 111 and is formed integrally with the first shell 111. The receiving cavity is a space in the shell assembly 10a for accommodating structural parts such as the optoelectronic assembly 15 (described below). The receiving cavity is formed by the first shell 111 and the rear shell 12. The specific shape of the receiving cavity is not limited here. The designer can make a reasonable design according to actual needs. It can be understood that the specific shape of the receiving cavity depends on the specific structure of the first shell 111 and the rear shell 12. The first shell 111 is the inner shell of the front shell 11. The first shell 111 can be, but is not limited to, detachably connected to the rear shell 12 by screwing, snapping or plugging. In the embodiment of the present application, the first shell 111 is snap-fitted and connected to the rear shell 12 by snap-fitting. The second shell 112 is the outer shell of the front shell 11. The second shell 112 can be completely covered on the outside of the first shell 111, or only on a part of the outside of the first shell 111. The second shell 112 can be formed into an integrated structure with the first shell 111 by injection molding or 3D printing, but is not limited to it.

[0026] The first housing 111 has a first port 111b, and the specific shape of the first port 111b is not limited here, and the designer can reasonably design it according to actual needs. For example, the specific shape of the first port 111b can be but not limited to a circle or a rectangle. The rear housing 12 has a second port 12a, and the specific shape of the second port 12a is not limited here, and the designer can reasonably design it according to actual needs. For example, the specific shape of the second port 12a can be but not limited to a circle or a rectangle. The first housing 111 is connected to the rear housing 12 so that the first port 111b is connected to the second port 12a.

[0027] like Figure 1-Figure 5 As shown, the seal 13 is a component in the shell assembly 10a for achieving effective sealing at the connection position between the first port 111b of the first shell 111 and the second port 12a of the rear shell 12. The specific form of the seal 13 will be described in detail below.

[0028] The sealing member 13 is located in the accommodating cavity and is disposed at the edge of the first port 111b of the first shell 111, so that when the first shell 111 is connected to the rear shell 12 so that the first port 111b and the second port 12a are butted, the sealing member 13 can effectively seal the connection position of the first port 111b of the first shell 111 and the second port 12a of the rear shell 12. Of course, the sealing member 13 can also be disposed at the edge of the second port 12a of the rear shell 12, so that when the first shell 111 is connected to the rear shell 12 so that the first port 111b and the second port 12a are butted, the sealing member 13 can double seal the connection position of the first port 111b of the first shell 111 and the second port 12a of the rear shell 12.

[0029] Part of the second housing 112 passes through the first housing 111 and is integrally formed with the seal 13, wherein the seal 13 may be, but is not limited to, an integral structure formed with the second housing 112 by injection molding or 3D printing. Of course, when the seal 13 is also disposed at the edge of the second port 12a of the rear housing 12, the seal 13 is also integrally formed with the rear housing 12.

[0030] Based on the shell assembly 10a in the embodiment of the present application, by designing a seal 13 and setting it at the edge of the first port 111b of the first shell 111, the seal 13 can play a good sealing role in the connection position between the first port 111b of the first shell 111 and the second port 12a of the rear shell 12, and effectively reduce the possibility of water vapor entering the accommodating cavity from the connection position between the first port 111b of the first shell 111 and the second port 12a of the rear shell 12 and burning the electronic components inside the lighting lamp head 10, thereby effectively enhancing the sealing of the shell assembly 10a of the lighting lamp head 10. By designing the first shell 111, the first shell 111 is mainly used to connect with the rear shell 12 as the inner shell of the front shell 11, so as to achieve the relative fixation of the position between the front shell 11 and the rear shell 12; by designing the second shell 112, the second shell 112 is mainly used to connect with the seal 13 as the outer shell of the front shell 11, so as to achieve the relative fixation of the position between the seal 13 and the front shell 11; by designing the first shell 111 and the second shell 112, the front shell 11 forms an inner and outer nested double shell structure, which can effectively enhance the structural strength of the front shell 11, so as to achieve the purpose of enhancing the overall structural strength of the shell assembly 10a, thereby enhancing the anti-fall performance of the lighting lamp head 10. By designing the second shell 112 and the first shell 111 to be integrally formed, the processing difficulty between the second shell 112 and the first shell 111 can be effectively reduced; by designing the seal 13 and the second shell 112 to be integrally formed, the processing difficulty between the seal 13 and the second shell 112 can be effectively reduced.

[0031] Furthermore, if Figure 1-Figure 5As shown, the specific processing method between the first shell 111 and the second shell 112 and the specific processing method between the seal 13 and the second shell 112 may be but is not limited to one or more of the following embodiments.

[0032] In the first embodiment, the second housing 112 is integrally formed with the first housing 111 by injection molding. In this design, the integral injection molding design of the second housing 112 and the first housing 111 can effectively reduce the difficulty of processing between the first housing 111 and the second housing 112.

[0033] In the second embodiment, the seal 13 is integrally formed with the second housing 112 by injection molding. In this design, on the one hand, the integral injection molding design of the seal 13 can effectively reduce the difficulty of processing between the seal 13 and the second housing 112, and on the other hand, the integral injection molding design of the seal 13 can achieve a better sealing effect on the connection position of the first port 111b of the first housing 111 and the second port 12a of the rear housing 12, thereby reducing the possibility of water seepage and damage to electronic components such as those inside the lighting lamp head 10 due to a gap at the connection position of the first port 111b of the first housing 111 and the second port 12a of the rear housing 12.

[0034] It should be noted that the first shell 111 is made of hard plastic injection molding to ensure the overall structural strength of the front shell 11 ; the seal 13 and the second shell 112 are made of soft plastic injection molding to facilitate the processing of the seal 13 and the design of the corresponding switch button on the second shell 112 .

[0035] Furthermore, if Figure 4-Figure 5As shown, the seal 13 includes an annular sealing ring 131; the first shell 111 is provided with two through holes 111c, the second shell 112 includes a shell body 112b and two connecting ends 112c, the shell body 112b is covered on the outside of the first shell 111, the two connecting ends 112c are arranged on the side of the shell body 112b facing the second port 12a of the rear shell 12, and the two connecting ends 112c pass through the two through holes 111c one by one and are connected to the annular sealing ring 131. The specific preparation material of the annular sealing ring 131 can be, but is not limited to, elastic silicone, elastic rubber or TPE (Thermoplasticelastomer, thermoplastic elastomer) and the like. In this design, by designing the seal 13 as an annular sealing ring 131, the annular sealing ring 131 can achieve circumferential sealing at the connection position between the first port 111b of the first shell 111 and the second port 12a of the rear shell 12, so as to effectively enhance the sealing effect of the shell assembly 10a; by designing the two connecting ends 112c of the second shell 112 to correspond to the two through holes 111c of the first shell 111 and connect with the annular sealing ring 131, the connection stability between the second shell 112 and the annular sealing ring 131 can be enhanced.

[0036] Of course, in some other embodiments, the seal 13 may also include multiple (more than two) sealing flanges (not shown in the figure), and the multiple sealing flanges are arranged at circumferential intervals along the first port 111b of the first shell 111, and the corresponding first shell 111 is provided with a plurality of through holes 111c equal to the number of the sealing flanges, and the second shell 112 includes a plurality of connecting ends 112c equal to the number of the sealing flanges, and each connecting end 112c of the second shell 112 passes through a corresponding one of the through holes 111c and is connected to a corresponding one of the sealing flanges.

[0037] Furthermore, if Figure 4-Figure 5 As shown, the cross section of the annular sealing ring 131 is L-shaped along the circumferential direction perpendicular to the annular sealing ring 131 (that is, along the extending direction perpendicular to the annular sealing ring 131). In this design, by designing the cross section of the annular sealing ring 131 to be L-shaped, the annular sealing ring 131 can effectively seal the front and side surfaces of the first housing 111, thereby further enhancing the sealing performance of the housing assembly 10a.

[0038] Of course, in some other embodiments, along the circumferential direction perpendicular to the annular sealing ring 131 , the cross-section of the annular sealing ring 131 may also be circular or rectangular.

[0039] Furthermore, if Figure 4-Figure 5As shown, a groove 111d is provided at the edge of the first port 111b of the first housing 111, and the seal 13 is embedded in the groove 111d. In this design, by designing the groove 111d at the edge of the first port 111b of the first housing 111 and embedding the seal 13 in the groove 111d, the contact area between the seal 13 and the first housing 111 can be increased, thereby enhancing the connection stability between the seal 13 and the first housing 111.

[0040] Please refer to Figure 6-Figure 7 As shown, the second aspect of the present application proposes a lighting lamp head 10, which has good sealing properties and can effectively reduce the possibility of water vapor entering the interior of the lighting headlamp and burning electronic components.

[0041] The lighting lamp head 10 includes a photoelectric component 15 and the shell component 10a. The first shell 111 and the second shell 112 have corresponding light emitting areas. The photoelectric component 15 is at least partially located in the accommodating cavity and is arranged corresponding to the light emitting area.

[0042] The light-emitting area is the area on the first shell 111 and the second shell 112 for the illumination light projected by the light source 152 (described below) of the optoelectronic component 15 to pass through the front shell 11. The light-emitting area can be a virtual light-transmitting structure or a real light-transmitting structure. For example, when the light-emitting area is a virtual light-transmitting structure, the light-emitting area of ​​the first shell 111 corresponds to the first light outlet 111a, and the first light outlet 111a is the opening on the first shell 111 for the illumination light projected by the light source 152 of the optoelectronic component 15 to pass through the outside of the front shell 11; the specific shape of the first light outlet 111a is not limited here, and the designer can make a reasonable design according to actual needs. For example, the specific shape of the first light outlet 111a can be but is not limited to a circle or a rectangle. The light exit area of ​​the second shell 112 corresponds to the second light exit 112a, which is an opening on the second shell 112 for the illumination light projected by the light source 152 of the optoelectronic component 15 to pass through the front shell 11. The specific shape of the second light exit 112a is not limited here, and the designer can reasonably design it according to actual needs. For example, the specific shape of the second light exit 112a can be but not limited to a circle or a rectangle. The first light exit 111a of the first shell 111 is arranged corresponding to the second light exit 112a of the second shell 112. The illumination light projected by the light source 152 of the optoelectronic component 15 passes through the first light exit 111a and the second light exit 112a in turn and passes through the front shell 11 to achieve the lighting effect. For another example, when the light emitting area is a solid light-transmitting structure, the light emitting areas of the first shell 111 and the second shell 112 may correspond to the lens 154, and the lens 154 may, but is not limited to, form an integrated structure with the first shell 111 and the second shell 112 by injection molding.

[0043] The optoelectronic component 15 is at least partially located in the accommodating cavity and is disposed corresponding to the light emitting area, so that the illumination light projected by the optoelectronic component 1515 can directly pass through the light emitting area and out of the front shell 11 to achieve the illumination effect.

[0044] Based on the lighting lamp holder 10 in the embodiment of the present application, by designing the seal 13 and setting it at the edge of the first port 111b of the first shell 111, the seal 13 can play a good sealing role at the connection position of the first port 111b of the first shell 111 and the second port 12a of the rear shell 12, effectively reducing the possibility of water vapor entering the accommodating cavity from the connection position of the first port 111b of the first shell 111 and the second port 12a of the rear shell 12 and burning the photoelectric component 15, thereby effectively reducing the safety hazard of the lighting lamp holder 10. By designing the first shell 111 and the second shell 112, the front shell 11 forms a double shell structure with inner and outer nesting, which can effectively enhance the structural strength of the front shell 11, so as to achieve the purpose of enhancing the overall structural strength of the lighting lamp holder 10, thereby enhancing the anti-fall performance of the lighting lamp holder 10. By designing the second shell 112 to be integrally formed with the first shell 111 and the seal 13 to be integrally formed with the second shell 112, the overall processing difficulty of the lighting lamp holder 10 can be effectively reduced.

[0045] Furthermore, if Figure 6-Figure 7 As shown, the lighting lamp head 10 further includes a mounting seat 14 , which is located in the accommodating cavity and connected to at least one of the first shell 111 and the rear shell 12 , and the optoelectronic component 15 is mounted on the mounting seat 14 .

[0046] Among them, the mounting seat 14 is used as a carrier of the optoelectronic component 15. The specific structure of the mounting seat 14 is not limited here, and the designer can reasonably design it according to actual needs. For example, the mounting seat 14 can be, but not limited to, a plate-like structure or a frame structure. The mounting seat 14 can be connected only to the first shell 111, can be connected only to the rear shell 12, or can be connected to both the first shell 111 and the rear shell 12. The specific connection method between the mounting seat 14 and the first shell 111 (rear shell 12) is not limited here, and the designer can reasonably design it according to actual needs; for example, when the mounting seat 14 and the first shell 111 (rear shell 12) are detachably connected, the mounting seat 14 can be, but not limited to, fixedly connected to the first shell 111 (rear shell 12) by at least one of screw connection, card connection or plug connection; for another example, when the mounting seat 14 and the first shell 111 (rear shell 12) are non-detachably connected, the mounting seat 14 can be, but not limited to, fixedly connected to the first shell 111 (rear shell 12) by gluing.

[0047] By designing the mounting seat 14, the mounting seat 14, on the one hand, serves as a carrier of the optoelectronic component 15 for carrying the optoelectronic component 15, and on the other hand, the mounting seat 14 is equivalent to a reinforcing rib designed in the accommodating cavity formed by the first shell 111 and the rear shell 12, which can enhance the structural strength of the front shell 11 and the rear shell 12.

[0048] Furthermore, if Figure 7 As shown, the mounting base 14 has a first side 14a arranged facing the light emitting area and a second side 14b arranged facing away from the light emitting area; the optoelectronic component 15 includes a circuit board 151, a light source 152 and a battery 153; the circuit board 151 is located on the first side 14a of the mounting base 14 and is connected to the mounting base 14; the light source 152 is arranged on a side of the circuit board 151 facing the light emitting area and is electrically connected to the circuit board 151; the battery 153 is located on the second side 14b of the mounting base 14 and is connected to the mounting base 14, and the battery 153 is electrically connected to the circuit board 151.

[0049] The first side 14a of the mounting seat 14 and the second side 14b of the mounting seat 14 are arranged at intervals in a direction perpendicular to the plane where the light exit area (specifically, the light exit port) is located. The specific connection method between the circuit board 151 and the mounting seat 14 is not limited here, and the designer can make a reasonable design according to actual needs; for example, when the circuit board 151 and the mounting seat 14 are detachably connected, the circuit board 151 can be, but not limited to, fixedly connected to the mounting seat 14 by at least one of screw connection, card connection or plug connection; for another example, when the circuit board 151 and the mounting seat 14 are non-detachably connected, the circuit board 151 can be, but not limited to, fixedly connected to the mounting seat 14 by gluing. The circuit board 151 can be a rigid circuit board 151, a flexible circuit board 151, or a rigid-flexible circuit board 151; it should be noted that when the circuit board 151 is a flexible circuit board 151 or a rigid-flexible circuit board 151, the optoelectronic component 15 also includes a reinforcing plate (not shown in the figure), which is arranged between the flexible circuit board 151 (rigid-flexible circuit board 151) and the first side 14a of the mounting seat 14 to provide support for the flexible circuit board 151 (rigid-flexible circuit board 151). The light source 152 can be, but is not limited to, an LED lamp, etc. The specific connection method between the battery 153 and the mounting seat 14 is not limited here, and the designer can make a reasonable design according to actual needs; for example, when the battery 153 and the mounting seat 14 are detachably connected, the battery 153 can be, but is not limited to, fixedly connected to the mounting seat 14 by snap-on connection. The battery 153 can be a storage battery 153 or a dry cell 153; if the battery 153 is a storage battery 153 and the rear shell 12 and the first shell 111 are detachably connected, when the power of the battery 153 is too low or zero, the user can remove the rear shell 12 and then take out the battery 153 and charge the battery 153 with the help of an external charger, or the user can directly charge the battery 153 by connecting the charging cable to the charging interface of the lighting lamp head 10; if the battery 153 is a dry cell 153 and the rear shell 12 and the first shell 111 are detachably connected, when the power of the battery 153 is too low or zero, the user can remove the rear shell 12 and then take out the old battery 153 and replace it with a new battery 153.

[0050] By designing the circuit board 151 , the light source 152 and the battery 153 , the battery 153 is electrically connected to the light source 152 through the circuit board 151 to provide the light source 152 with the electrical energy required for lighting.

[0051] Of course, the optoelectronic component 15 also includes a lens 154, which is arranged on the light-emitting side of the light source 152. The lens 154 can be, but is not limited to, fixedly connected to the first shell 111 by means of locking screws or injection molding. The lens 154 is light-transmitting. At this time, the lens 154 is equivalent to the light-emitting area of ​​the first shell 111 and the second shell 112.

[0052] A third aspect of the present application provides a headlamp device, which has good sealing properties and can effectively reduce the possibility of water vapor entering the interior of the lighting headlamp and burning electronic components.

[0053] The headlamp device includes a head-mounted assembly (not shown in the figure) and the above-mentioned lighting lamp head 10; the above-mentioned lighting lamp head 10 also includes a mounting bracket 16, the mounting bracket 16 is rotatably connected to the rear shell 12, and the mounting bracket 16 has a lamp head mounting position; the head-mounted assembly is connected to the mounting bracket 16 corresponding to the lamp head mounting position. Among them, the specific structure of the mounting bracket 16 is not limited here, and the designer can reasonably design it according to actual needs. For example, the mounting bracket 16 can be but not limited to a plate-like structure or a grid structure.
