Technical Field

[0001] The utility model relates to the technical field of flashlights, and particularly to a lamp head structure and a flashlight.

Background Art

[0002] With the progress of flashlight lighting technology, flashlights are no longer limited to basic lighting functions. By adding a camera module, they have become camera flashlights with photo and video recording functions. However, during the use of a flashlight, the strong light emitted by the lighting module will seriously interfere with the normal shooting of the camera module, resulting in problems such as blurred picture quality in the pictures taken by the camera module, and thus poor shooting quality. The existing light-shielding design for the camera module in camera flashlights is simple and difficult to avoid the interference of the light emitted by the lighting module on the normal shooting of the camera module. How to improve the light-shielding effect has become an urgent technical problem to be solved currently.

Content of the Utility Model

[0003] To solve the above problems, the utility model provides a lamp head structure and a flashlight.

[0004] To solve the above technical problems, in one embodiment, the utility model provides a lamp head structure. The lamp head structure includes a light-shielding component and a lens. The light-shielding component is arranged on the lens. The direction in which light passes through the lens and emits is defined as the light-emitting direction, and the end of the light-shielding component connected to the lens is defined as the connection end. The light-shielding component includes a convex portion, and the connection end extends along the light-emitting direction to form the convex portion.

[0005] Preferably, the convex portion includes a first convex member and a second convex member. The first convex member is sleeved on the second convex member.

[0006] Preferably, the light-shielding component further includes a lens protection member. A second receiving groove corresponding to the lens protection member is arranged on the side of the second convex member away from the lens, and the lens protection member is arranged between the first receiving groove and the second receiving groove.

[0007] Preferably, the lens is provided with a third receiving groove corresponding to the second convex member, and the second convex member is connected in cooperation with the third receiving groove.

[0008] Preferably, the ratio of the height of the convex portion to the inner diameter width is between 0.1 and 0.4.

[0009] Preferably, the light-shielding component is provided with a light-emitting hole along the light-emitting direction, and a chamfer is arranged at one end of the light-emitting hole away from the lens.

[0010] Preferably, at least one side of the convex portion is provided with a limiting hole, the lamp head structure includes a limiting member, and the limiting member passes through the limiting hole and is sequentially connected to the convex portion and the lens.

[0011] Preferably, limiting portions are formed by outward protrusions on opposite sides of the convex portion, and the limiting holes are formed on the limiting portions.

[0012] Preferably, the lamp head structure further includes a camera, the lens includes a hollow light-shielding cylinder arranged in a direction opposite to the light-emitting direction, the camera is connected to the light-shielding component, and the hollow light-shielding cylinder is sleeved on the camera.

[0013] To solve the above technical problems, in another embodiment, the present invention provides a flashlight, which includes a barrel and the above-mentioned lamp head structure, and the lamp head structure is arranged at one end of the barrel facing the light-emitting direction.

[0014] Compared with the prior art, the lamp head structure and the flashlight of the present invention have the following advantages:

[0015] 1. The lamp head structure in an embodiment of the present invention includes a light-shielding component and a lens. The light-shielding component is arranged on the lens. The direction in which light passes through the lens and emits is defined as the light-emitting direction, and the end where the light-shielding component is connected to the lens is defined as the connection end. The light-shielding component includes a convex portion, and the connection end extends along the light-emitting direction to form the convex portion. By providing the convex portion, the convex portion extends along the light-emitting direction starting from the connection end, so that the light inside the flashlight is still blocked by the convex portion within a certain distance after passing through the lens. The convex portion forms a physical barrier to the light emitted by the flashlight, improving the light-shielding effect; the convex portion extends and protrudes along the light-emitting direction relative to the lens, forming an effective light-shielding barrier, which can prevent the light in the illumination light path of the flashlight from affecting the normal shooting of the flashlight.

[0016] 2. The convex portion in an embodiment of the present invention includes a first convex member and a second convex member. The first convex member is sleeved on the second convex member; a first accommodation groove corresponding to the second convex member is formed on one side of the first convex member facing the lens, and the second convex member is cooperatively connected with the first accommodation groove. By providing that the convex portion includes a first convex member and a second convex member, the cooperation relationship between the two makes the positional relationship of the convex portion more stable on the one hand, and improves the light-shielding effect and reduces the possibility of halo and overexposure on the other hand; the positional relationship between the first convex member and the second convex member is also convenient for assisting in fixing when adding components such as a new filter or a lens protection member.

[0017] 3. The light-shielding component in an embodiment of the present utility model further includes a lens protection member. A second receiving groove corresponding to the lens protection member is provided on the side of the second protruding member away from the lens, and the lens protection member is arranged between the first receiving groove and the second receiving groove. By providing the second receiving groove corresponding to the lens protection member on the side of the second protruding member away from the lens and arranging the lens protection member between the first receiving groove and the second receiving groove, the first protruding member and the second protruding member enclose to play a role in receiving and fixing the lens protection member. The lens protection member has the advantages of high hardness and good light transmittance, can resist scratching and abrasion, protect the lens from being damaged, and at the same time allows light to pass through fully without affecting the imaging quality of shooting. The lens protection member can also prevent dust and other particles from adhering to the lens, further ensuring the shooting effect.

[0018] 4. A third receiving groove corresponding to the second protruding member is provided on the lens in an embodiment of the present utility model, and the second protruding member is connected in cooperation with the third receiving groove. By providing the third receiving groove corresponding to the second protruding member on the lens, compared with the first protruding member directly arranged on the lens, the end of the second protruding member close to the lens extends into the third receiving groove of the lens and is connected in cooperation with the third receiving groove, which not only makes the assembly alignment of the two more convenient, but also makes the positional relationship between the two more stable. The first protruding member and the second protruding member achieve a hierarchical cooperation relationship with the lens, so that a stable positional relationship is formed between the protruding part and the lens, preventing the protruding part from blocking the shooting of the flashlight due to relative displacement of the protruding part with respect to the lens.

[0019] 5. In an embodiment of the present utility model, the ratio of the height of the protruding part to the inner diameter width is between 0.1 and 0.4. If the height of the protruding part is too large relative to the inner diameter width, it will cause the protruding part to be too protruding, which is not only inconvenient for carrying and storing, but also the standing shape of the protruding part itself limits the shooting angle range. If the height of the protruding part is too small relative to the inner diameter width, the light-shielding range established by the protruding part will be too short, and the light emitted by the flashlight may still interfere with the normal shooting of the flashlight after reflection or diffuse reflection. Setting the ratio of the height of the protruding part to the inner diameter width between 0.1 and 0.4 can not only ensure that the protruding part is not too protruding to limit the shooting angle of the flashlight, but also ensure that the protruding part has a sufficient light-shielding range, and can fully avoid the interference of the light emitted by the flashlight.

[0020] 6. An optical aperture is provided in the light-shielding component in an embodiment of the present utility model along the light-emitting direction, and a chamfer is provided at the end of the optical aperture away from the lens. By providing a chamfer at the end of the optical aperture away from the lens, the chamfer can reduce the occlusion of the end of the light-shielding component away from the lens on the imaging angle of the flashlight, so that the flashlight has a larger imaging angle.

[0021] 7. In at least one side of the convex part in an embodiment of the present utility model, a limiting hole is provided. The lamp head structure includes a limiting member, and the limiting member passes through the limiting hole and is sequentially connected to the convex part and the lens. By providing the limiting hole in at least one side of the convex part, the limiting member can pass through the limiting hole and be sequentially connected to the convex part and the lens, so as to realize stable fixed constraint on the convex part, prevent the relative displacement between the convex part and the lens caused by the loosening of the connection relationship, and block the normal shooting of the flashlight.

[0022] 8. In an embodiment of the present utility model, limiting parts are formed by outward protrusions on the opposite sides of the convex part, and the limiting holes are provided on the limiting parts. By forming the limiting parts by outward protrusions on the opposite sides of the convex part and providing the limiting holes on the limiting parts, a limiting structure with the limiting holes arranged on the opposite sides of the convex part is formed. When the convex part is fixed, the force on the convex part is more uniform, avoiding deformation or damage caused by uneven force and improving the stability of the structure.

[0023] 9. In an embodiment of the present utility model, the lamp head structure further includes a camera. The lens includes a hollow light-shielding cylinder arranged in the direction opposite to the light-emitting direction. The camera is connected to the light-shielding component, and the hollow light-shielding cylinder is sleeved on the camera. By setting the camera to be connected to the light-shielding component, the convex part of the light-shielding component can be in a convex shape, effectively avoiding the influence of the light emitted by the light source on the normal shooting of the camera. And the lens includes a hollow light-shielding cylinder arranged in the direction opposite to the light-emitting direction, and the hollow light-shielding cylinder is sleeved on the camera, so that the hollow light-shielding cylinder plays a role of a barrier for the camera. On the one hand, it limits the position of the camera, and on the other hand, it further shields the interference of the light emitted by the light source to the camera.

[0024] 10. In an embodiment of the present utility model, the flashlight includes a barrel and the above-mentioned lamp head structure, and the lamp head structure is arranged at one end of the barrel facing the light-emitting direction. The flashlight has the same beneficial effects as the lamp head structure and will not be elaborated here.

Detailed implementation manners

[0036] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the attached drawings and implementation examples. It should be understood that the specific implementation examples described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0037] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0038] In the present utility model, the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "front", "rear", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal", etc. is based on the orientation or positional relationship shown in the drawings. These terms are mainly used to better describe the present utility model and its embodiments, and are not used to limit that the indicated device, element or component must have a specific orientation, or be constructed and operated in a specific orientation.

[0039] Moreover, in addition to being able to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present utility model can be understood according to specific circumstances.

[0040] In addition, the terms "mounted", "arranged", "provided with", "connected", "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there can be internal communication between two devices, elements or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0041] Please refer to Figure 1 and Figure 2 , the first embodiment of the present utility model provides a lamp head structure 10. The lamp head structure 10 includes a light-shielding component 20 and a lens 30. The light-shielding component 20 is arranged on the lens 30. The direction in which light passes through the lens 30 and emits is defined as the light-emitting direction. One end of the light-shielding component 20 connected to the lens 30 is defined as the connection end 21. The light-shielding component 20 includes a convex portion 22. The connection end 21 extends along the light-emitting direction to form the convex portion 22.

[0042] It can be understood that by providing the convex portion 22, the convex portion 22 extends along the light-emitting direction starting from the connection end 21, so that within a certain distance after the light emits from the lens 30, the light is still blocked by the convex portion 22. The convex portion 22 forms a physical barrier to the light emitted from the lens 30, improving the light-shielding effect; the convex portion 22 extends and protrudes along the light-emitting direction relative to the lens 30, forming an effective light-shielding barrier, which can prevent the light emitted from the lens 30 from affecting the normal shooting of the flashlight 1.

[0043] As a specific implementation, a condenser lens 33 and a floodlight lens 34 are provided on the side of the lens 30 away from the convex portion 22. The light refracted by the condenser lens 33 or the floodlight lens 34 passes through the lens 30 and exits. After the light leaves the lens 30, due to the presence of the convex portion 22, the light emitted in the direction of the convex portion 22 will be blocked, and the light cannot interfere with the imaging optical path of the flashlight 1 because of the occlusion of the convex portion 22.

[0044] Please refer to Figures 2 to 4 Furthermore, the convex portion 22 includes a first convex member 221 and a second convex member 222. The first convex member 221 is sleeved on the second convex member 222; a first receiving groove 2211 corresponding to the second convex member 222 is formed on the side of the first convex member 221 facing the lens 30, and the second convex member 222 is cooperatively connected with the first receiving groove 2211.

[0045] It can be understood that by setting the convex portion 22 to include the first convex member 221 and the second convex member 222, the cooperation relationship between the two makes the positional relationship of the convex portion 22 more stable on the one hand, and improves the light-shielding effect on the other hand, reducing the possibility of halos and overexposure; the positional relationship between the first convex member 221 and the second convex member 222 is also convenient for assisting in fixing when adding components such as a new filter or a lens protector 23.

[0046] Please refer to Figures 1 to 4 Furthermore, the light-shielding component 20 further includes a lens protector 23. A second receiving groove 2221 corresponding to the lens protector 23 is provided on the side of the second convex member 222 away from the lens 30, and the lens protector 23 is disposed between the first receiving groove 2211 and the second receiving groove 2221.

[0047] It can be understood that by providing a second receiving groove 2221 corresponding to the lens protector 23 on the side of the second convex member 222 away from the lens 30, and the lens protector 23 is disposed between the first receiving groove 2211 and the second receiving groove 2221, the enclosure of the first convex member 221 and the second convex member 222 plays a role in receiving and fixing the lens protector 23. The lens protector 23 has the advantages of high hardness and good light transmittance, can resist scratching and abrasion, protect the lens from being damaged, and at the same time allows light to pass through fully without affecting the imaging quality of shooting. The lens protector 23 can also prevent dust and other particles from adhering to the lens, further ensuring the shooting effect. Since there is a gap for preventing scratching between the lens protector 23 and the camera 40, the setting of the second convex member 222 can not only play a light-shielding role but also seal this gap, playing a waterproof and dustproof sealing role.

[0048] Specifically, as a preferred implementation, the lens protector 23 is tempered glass.

[0049] Understandably, tempered glass has a high surface hardness, good scratch resistance, and is not easily scratched. Tempered glass also has high optical clarity. These characteristics have little impact on the imaging effect of shooting and can ensure the shooting quality.

[0050] Please combine Figures 2 to 4 , further, the lens 30 is provided with a third receiving groove 31 corresponding to the second convex member 222, and the second convex member 222 is connected to the third receiving groove 31 in a matching manner.

[0051] Understandably, by providing the third receiving groove 31 corresponding to the second convex member 222 on the lens 30, compared with the first convex member 221 being directly provided on the lens 30, one end of the second convex member 222 close to the lens 30 extends into the third receiving groove 31 of the lens 30 and is connected to the third receiving groove 31 in a matching manner, which can not only make the assembly alignment of the two more convenient but also make the positional relationship between the two more stable. The first convex member 221 and the second convex member 222 achieve a hierarchical matching relationship with the lens 30, making the convex portion 22 and the lens 30 form a stable positional relationship, preventing the convex portion 22 from blocking the shooting of the flashlight 1 due to relative displacement of the convex portion 22 with respect to the lens 30.

[0052] Please combine Figure 1 and Figure 5 , further, the ratio of the height to the width of the convex portion 22 is between 0.1 and 0.4.

[0053] It should be noted that the height of the convex portion 22 is defined as h, and the inner diameter width of the convex portion is d, and 0.1 ≤ h / d ≤ 0.4.

[0054] Understandably, if the height of the convex portion 22 is too large relative to the inner diameter width dimension, the convex portion 22 will be too convex, which is not only inconvenient for carrying and storage but also limits the shooting angle range due to the shape of the convex portion 22 standing upright. If the height of the convex portion 22 is too small relative to the inner diameter width dimension, the light-shielding range established by the convex portion 22 will be too short, and the light emitted by the flashlight 1 may still interfere with the normal shooting of the flashlight 1 after reflection or diffuse reflection. By setting the ratio of the height of the convex portion 22 to the inner diameter width between 0.1 and 0.4, it can not only prevent the convex portion 22 from being too convex to limit the shooting angle of the flashlight 1 but also ensure that the convex portion 22 has a sufficient light-shielding range, and can fully avoid the interference effect of the light emitted by the flashlight 1.

[0055] Please combine Figure 1 and Figure 4 , further, the light-shielding component 20 is provided with a light-emitting hole 24 along the light-emitting direction, and a chamfer 241 is provided at one end of the light-emitting hole 24 away from the lens 30.

[0056] Understandably, by providing a chamfer 241 at one end of the light-emitting aperture 24 away from the lens 30, the chamfer 241 can reduce the occlusion of the end of the light-shielding component 20 away from the lens 30 from the camera view angle of the flashlight 1, enabling the flashlight 1 to have a larger camera view angle.

[0057] Please refer to Figures 1 to 3 , furthermore, at least one side of the convex portion 22 is provided with a limiting hole 2231, and the lamp head structure 10 includes a limiting member 11. The limiting member 11 passes through the limiting hole 2231 and sequentially connects the convex portion 22 and the lens 30.

[0058] Understandably, by providing a limiting hole 2231 on at least one side of the convex portion 22, the limiting member 11 can pass through the limiting hole 2231 to sequentially connect the convex portion 22 and the lens 30, realizing stable fixed restraint on the convex portion 22, preventing relative displacement between the convex portion 22 and the lens 30 due to loose connection, and blocking and affecting the normal shooting of the flashlight 1. At the same time, it also makes it more convenient to disassemble and replace the lens protection member 23.

[0059] As a specific implementation manner, the limiting member 11 is a bolt, and the limiting hole 2231 is an internal thread hole.

[0060] Please continue to refer to Figures 1 to 3 , furthermore, limiting portions 223 are formed by outward protrusions on opposite sides of the convex portion 22, and the limiting holes 2231 are provided on the limiting portions 223.

[0061] Understandably, by forming limiting portions 223 by outward protrusions on opposite sides of the convex portion 22 and providing the limiting holes 2231 on the limiting portions 223, a limiting structure with the limiting holes 2231 provided on opposite sides of the convex portion 22 is formed. When the convex portion 22 is fixed, the convex portion 22 is more evenly stressed, avoiding deformation or damage caused by uneven stress and improving the structural stability.

[0062] Please continue to refer to Figures 1 to 3 , furthermore, the lamp head structure 10 further includes a camera 40. The lens 30 includes a hollow light-shielding cylinder 32 arranged in a direction opposite to the light-emitting direction. The camera 40 is connected to the light-shielding component 20, and the hollow light-shielding cylinder 32 is sleeved on the camera 40.

[0063] Understandably, by setting the camera 40 to be connected to the light-shielding component 20, the convex portion 22 of the light-shielding component 20 can effectively avoid the influence of the light emitted by the light source on the normal shooting of the camera 40 in a convex shape. The lens 30 includes a hollow light-shielding cylinder 32 arranged in the direction opposite to the light-emitting direction. The hollow light-shielding cylinder 32 is sleeved on the camera 40, so that the hollow light-shielding cylinder 32 plays a role of a barrier to the camera 40. On the one hand, it limits the position of the camera 40, and on the other hand, it further shields the interference of the light emitted by the light source to the camera 40.

[0064] Please refer to the figure. The second embodiment of the present invention provides a flashlight 1, which includes a barrel 50 and the lamp head structure 10 of the first embodiment of the present invention. The lamp head structure 10 is arranged at one end of the barrel 50 facing the light-emitting direction.

[0065] Understandably, the flashlight 1 has the same beneficial effects as the lamp head structure 10, which will not be elaborated here.

[0066] Optionally, please combine Figure 1 、 Figure 2 and Figure 5 , the lamp head structure 10 further includes a laser indicator 36 and a warning light guide column 35. The laser indicator 36 is arranged on one side of the lens 30 facing the light-emitting direction. The warning light guide column 35 is penetrated through the lens 30. A warning lamp 37 is arranged on the side of the warning light guide column 35 facing away from the light-emitting direction. A gravity sensor 51 is also arranged in the barrel 50. The gravity sensor 51 is electrically connected to the warning lamp 37.

[0067] Understandably, since the lamp head structure 10 includes a laser indicator 36, and the laser indicator 36 is arranged on one side of the lens 30 facing the light-emitting direction, the laser indicator 36 can be used for indicative irradiation during use to make a more convenient indicative mark for the target, which is more targeted. The warning light guide column 35 is penetrated through the lens 30. A warning lamp 37 is arranged on the side of the warning light guide column 35 facing away from the light-emitting direction. A gravity sensor 51 is also arranged in the barrel 50. The gravity sensor 51 is electrically connected to the warning lamp 37. The above settings enable the flashlight 1 to have a static induction function. The gravity sensor 51 senses the gravity change. When the gravity no longer changes within a certain period of time, a warning light will be emitted through the electrically connected warning lamp 37. The warning light is conducted to the outside through the warning light guide column 35 to send out a light warning message to the outside for reminder, further improving the intelligence and humanization level of the flashlight 1.

[0068] Optionally, a warning light guide column 35 is arranged on each side of the laser indicator 36, and the warning lamp 37 can emit red / blue light.

[0069] Compared with the prior art, the lamp head structure and flashlight of the present invention have the following advantages:

[0070] 1. The lamp head structure in an embodiment of the present utility model includes a light-shielding component and a lens. The light-shielding component is disposed on the lens. The direction in which light passes through the lens and emits is defined as the light-emitting direction, and the end where the light-shielding component is connected to the lens is defined as the connection end. The light-shielding component includes a convex portion, and the connection end extends along the light-emitting direction to form the convex portion. By providing the convex portion, which extends along the light-emitting direction starting from the connection end, the light inside the flashlight is still blocked by the convex portion within a certain distance after passing through the lens. The convex portion forms a physical barrier to the light emitted by the flashlight, improving the light-shielding effect. The convex portion extends and protrudes along the light-emitting direction relative to the lens, forming an effective light-shielding barrier, which can prevent the light in the illumination optical path of the flashlight from affecting the normal shooting of the flashlight.

[0071] 2. The convex portion in an embodiment of the present utility model includes a first convex member and a second convex member. The first convex member is sleeved on the second convex member. A first receiving groove corresponding to the second convex member is provided on the side of the first convex member facing the lens, and the second convex member is connected in cooperation with the first receiving groove. By providing that the convex portion includes a first convex member and a second convex member, the cooperation relationship between the two makes the positional relationship of the convex portion more stable on the one hand, and improves the light-shielding effect and reduces the possibility of halo and overexposure on the other hand. The positional relationship between the first convex member and the second convex member is also convenient for assisting in fixing when adding components such as a new filter or a lens protection member.

[0072] 3. The light-shielding component in an embodiment of the present utility model further includes a lens protection member. A second receiving groove corresponding to the lens protection member is provided on the side of the second convex member away from the lens, and the lens protection member is disposed between the first receiving groove and the second receiving groove. By providing a second receiving groove corresponding to the lens protection member on the side of the second convex member away from the lens, and the lens protection member is disposed between the first receiving groove and the second receiving groove, the first convex member and the second convex member enclose to play a role in receiving and fixing the lens protection member. The lens protection member has the advantages of high hardness and good light transmittance, can resist scratching and abrasion, protect the lens from being damaged, and at the same time allows light to pass through fully without affecting the imaging quality of shooting. The lens protection member can also prevent dust and other particles from adhering to the lens, further ensuring the shooting effect.

[0073] 4. In an embodiment of the present utility model, the lens is provided with a third receiving groove corresponding to the second convex member, and the second convex member is cooperatively connected with the third receiving groove. By providing the third receiving groove corresponding to the second convex member on the lens, compared with directly providing the first convex member on the lens, the second convex member extends into the third receiving groove of the lens near one end of the lens and is cooperatively connected with the third receiving groove, which can not only make the assembly alignment of the two more convenient, but also make the positional relationship between the two more stable. The first convex member and the second convex member achieve a hierarchical cooperative relationship with the lens, so that a stable positional relationship is formed between the convex part and the lens, preventing the convex part from blocking the shooting of the flashlight due to relative displacement of the convex part with respect to the lens.

[0074] 5. In an embodiment of the present utility model, the ratio of the height of the convex part to the inner diameter width is between 0.1 and 0.4. If the height of the convex part is too large relative to the inner diameter width, it will cause the convex part to be too convex, which is not only inconvenient for carrying and storage, but also limits the shooting angle range due to the standing shape of the convex part itself. If the height of the convex part is too small relative to the inner diameter width, the shading range established by the convex part will be too short, and the light emitted by the flashlight may still interfere with the normal shooting of the flashlight after reflection or diffuse reflection. By setting the ratio of the height of the convex part to the inner diameter width between 0.1 and 0.4, it can not only ensure that the convex part is not too convex to limit the shooting angle of the flashlight, but also ensure that the convex part has a sufficient shading range, and can fully avoid the interference of the light emitted by the flashlight.

[0075] 6. In an embodiment of the present utility model, the light-shielding component is provided with a light-emitting hole along the light-emitting direction, and a chamfer is provided at one end of the light-emitting hole far from the lens. By providing a chamfer at one end of the light-emitting hole far from the lens, the chamfer can reduce the occlusion of the end of the light-shielding component far from the lens on the shooting angle of the flashlight, so that the flashlight has a larger shooting angle.

[0076] 7. In an embodiment of the present utility model, at least one side of the convex part is provided with a limiting hole, and the lamp head structure includes a limiting member, and the limiting member passes through the limiting hole to connect the convex part and the lens in sequence. By providing at least one side of the convex part with a limiting hole, the limiting member can pass through the limiting hole to connect the convex part and the lens in sequence, realizing stable fixed constraint on the convex part, preventing the convex part from having relative displacement with the lens due to loosening of the connection relationship, and blocking the normal shooting of the flashlight.

[0077] 8. In an embodiment of the present utility model, the opposite sides of the convex part bulge outwards to form limiting parts, and the limiting holes are provided on the limiting parts. By bulging outwards on the opposite sides of the convex part to form limiting parts and providing the limiting holes on the limiting parts, a limiting structure with the limiting holes provided on the opposite sides of the convex part is formed. When the convex part is fixed, the convex part is more evenly stressed, avoiding deformation or damage caused by uneven stress, and improving the structural stability.

[0078] 9. The lamp head structure in an embodiment of the present utility model further includes a camera. The lens includes a hollow light-shielding cylinder disposed in a direction opposite to the light-emitting direction. The camera is connected to the light-shielding component, and the hollow light-shielding cylinder is sleeved on the camera. By setting the connection between the camera and the light-shielding component, the convex portion of the light-shielding component can effectively avoid the influence of the light emitted by the light source on the normal shooting of the camera in a convex shape. And the lens includes a hollow light-shielding cylinder disposed in a direction opposite to the light-emitting direction, and the hollow light-shielding cylinder is sleeved on the camera, so that the hollow light-shielding cylinder plays a role of a barrier for the camera. On the one hand, it limits the position of the camera, and on the other hand, it further shields the interference of the light emitted by the light source to the camera.

[0079] 10. The flashlight in an embodiment of the present utility model includes a barrel and the above lamp head structure, and the lamp head structure is disposed at one end of the barrel facing the light-emitting direction. The flashlight has the same beneficial effects as the lamp head structure, which will not be elaborated here.

[0080] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the principle of the present utility model shall be included in the protection scope of the present utility model.
