Description

Technical Field

[0001] This utility model relates to the field of photographic equipment technology, and in particular to a fill light with a detachable light shield. Background Technology

[0002] Currently, in the photography and videography industry, supplementary lighting is commonly used. With the development of supplementary lighting technology in photography and videography, lens hoods have become a core accessory for controlling the direction of light and reducing stray light, and they are placed at the light outlet of the supplementary light.

[0003] In existing technologies, the fixing methods for sunshades have generally achieved the function of being detachable, but they have significant drawbacks in terms of reliability and durability: (1) Magnetic fixation: It relies on magnetic attraction to fix and remove, but in the case of severe vibration or shaking (such as vehicle shooting or motion shooting), the light shield is easy to accidentally fall off the fill light.

[0004] (2) Rotary snap-fit ​​fixation: The locking and disassembly are achieved by using the combination of the snap and the slot. However, frequent disassembly and assembly of the sunshade can cause wear due to the relative rotation of the snap and the slot, resulting in the sunshade becoming loose and leaking light. In addition, dust and oil entering the slot will exacerbate structural failure.

[0005] (3) Elastic buckle fixing: The buckle and the slot are used to lock and disassemble by plastic deformation. However, frequent disassembly and assembly of the sunshade can cause the buckle to fatigue and break, resulting in the sunshade becoming loose. Utility Model Content

[0033] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0034] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification and claims of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0035] The directional terms such as "up," "down," "left," "right," "front," "back," "top," and "bottom" (if present) used in the specification and claims of this utility model are defined according to the position of the structures in the drawings and the relative positions of the structures, and are only for the purpose of clarity and convenience in expressing the technical solution. It should be understood that the use of directional terms should not limit the scope of protection claimed in this application.

[0036] Please see Figures 1-5 and Figures 12-13 A supplementary light with a detachable light shield includes a housing 10, a light source 20, a heat dissipation module 30, and a light shield 40. The housing 10 forms an inner cavity 15. The light source 20 is disposed in the inner cavity 15, and its light outlet 21 is exposed on the surface of the housing 10 through a first through hole 12. The heat dissipation module 30 is disposed in the inner cavity 15 and includes a heat dissipation fin assembly 31 and a heat dissipation fan 32. The light source 20 and the heat dissipation fan 32 are respectively disposed at opposite ends of the heat dissipation fin assembly 31. The light shield 40 is disposed on the surface of the housing 10 and located on the outer periphery of the light outlet 21.

[0037] The sunshade 40 is locked to the surface of the housing 10 by a locking structure, which includes a protrusion 41 on the outer side wall of the sunshade 40, a locking member 50 for restricting the movement of the sunshade 40, an unlocking member 60 for releasing the restriction of the movement of the sunshade 40 by the locking member 50, and a mounting groove 11 recessed on the surface of the housing 10.

[0038] The mounting groove 11 surrounds the outer periphery of the light outlet 21. The mounting groove 11 includes an annular groove 111 that mates with the body of the light shield 40, a mating groove 112 that mates with the protrusion 41, and a locking groove 113 for the protrusion 41 to slide. The locking groove 113 extends circumferentially along the annular groove 111 and communicates with the inner cavity 15 through the second through hole 13 of the housing 10. The annular groove 111, the mating groove 112, and the locking groove 113 are interconnected.

[0039] More specifically, the number of protrusions 41 corresponds one-to-one with the number of mating grooves 112 and locking grooves 113. The number of protrusions 41 can be one or more; when multiple protrusions 41 are provided on the light shield 40, these protrusions 41 are evenly distributed circumferentially on the outer wall of the light shield 40. Correspondingly, multiple mating grooves 112 and multiple locking grooves 113 are evenly distributed cylindrically on the outer periphery of the annular groove 111. It is understood that too few or too many protrusions 41 and mating grooves 112 will reduce the convenience of installing the light shield 40 onto the housing 10. In this embodiment, the light shield 40 is provided with three protrusions 41, and correspondingly, the number of mating grooves 112 and locking grooves 113 are both three.

[0040] More specifically, the locking element 50 and the unlocking element 60 correspond one to one. In this embodiment, the number of locking elements 50 and the number of unlocking elements 60 are both one.

[0041] The locking member 50 is elastically disposed on the heat dissipation fin assembly 31 and can extend from the inner cavity 15 into one of the locking grooves 113. The unlocking member 60 is elastically connected to the heat dissipation fin assembly 31, with one end of the unlocking member 60 abutting against the locking member 50 and the other end exposed on the surface of the housing 10. In this embodiment, the locking member 50 and the unlocking member 60 are arranged perpendicularly.

[0042] In the locked state, the protrusion 41 is located in the locking groove 113, and the locking member 50 extends into the locking groove 113 to restrict the protrusion 41 from sliding out of the locking groove 113.

[0043] In the unlocked state, by pressing the unlocking component 60, the unlocking component 60 drives the locking component 50 to completely exit the locking groove 113, thereby releasing the restriction of the locking component 50 on the protrusion 41 sliding out of the locking groove 113.

[0044] As described above, the supplementary light with a detachable light shield provided by this utility model, through the cooperation of the light shield 40, locking structure, and heat dissipation fin assembly 31, allows the light shield 40 to be installed on the surface of the housing 10, enables the locking member 50 to restrict the rotation of the light shield 40, and allows the unlocking member 60 to release the restriction of the locking member 50 on the rotation of the light shield 40, thus realizing the installation, locking, and detachability of the light shield 40; the locking member 50 of this utility model can lock the light shield 40 to prevent it from accidentally falling off, compared with the light shield in the prior art The magnetic fastening of the cover provides better reliability. The locking element 50 and the protrusion 41 are less prone to wear and breakage, offering better durability compared to the rotational snap-fit ​​and elastic buckle fastening methods used in existing light shields. Integrating the locking element 50 into the heat dissipation fin assembly 31 simplifies and compacts the internal structure of the fill light with a detachable light shield, reducing its size and increasing portability. Therefore, the fill light with a detachable light shield provided by this invention not only allows for the installation, locking, and detachment of the light shield 40, but also offers superior reliability and durability.

[0045] Please see Figure 5 , Figure 9 and Figure 10 The unlocking member 60 has a pressing block 62 elastically connected to the heat dissipation fin assembly 31 and an inclined guide arm 61 connected to the pressing block 62. The pressing block 62 is exposed on the surface of the housing 10. The inclined guide arm 61 abuts against the locking member 50 and is used to drive the locking member 50 into or out of the locking groove 113.

[0046] More specifically, in this embodiment, the unlocking member 60 has two spaced-apart inclined guide arms 61, and the two inclined guide arms 61 are parallel.

[0047] Furthermore, the pressing block 62 is elastically connected to the heat dissipation fin assembly 31 via a first elastic element 70. The first elastic element 70 is sleeved on the outer periphery of the two inclined guide arms 61, and its two ends abut against the pressing block 62 and the heat dissipation fin assembly 31, respectively. In this embodiment, the first elastic element 70 is a spring.

[0048] More specifically, the pressing block 62 has an abutting piece 621 that abuts against the housing 10 and a limiting piece 622 that extends toward the heat dissipation fin assembly 31. The abutting piece 621 is used to prevent the pressing block 62 from detaching from the housing 10, and the limiting piece 622 is used to limit the degree of compression of the first elastic member 70 to avoid the inclined guide arm 61 protruding excessively toward the heat dissipation fin assembly 31 and causing a collision.

[0049] Please see Figure 8 and Figure 10The locking member 50 has a locking arm 51 that can extend into the locking groove 113 and an abutting post 52 that abuts against the inclined guide arm 61. The abutting post 52 is provided with a first inclined guide groove 521 that cooperates with the inclined guide arm 61.

[0050] Furthermore, the abutment post 52 has two first oblique guide grooves 521, which are formed on the side wall of the abutment post 52.

[0051] More specifically, the outer diameter of the locking arm 51 is smaller than the outer diameter of the abutment post 52, and an abutment surface 53 is formed at the connection between the locking arm 51 and the abutment post 52.

[0052] Please see Figures 5-7 and Figure 10 The heat dissipation fin assembly 31 is provided with a mounting block 33 for fixing the locking member 50. The mounting block 33 is provided with a fixing hole 331. A fastener 34 is provided at the open end of the fixing hole 331 to restrict the abutment post 52 within the fixing hole 331. The abutment post 52 is elastically disposed within the fixing hole 331 by a second elastic member 80. The locking arm 51 can pass through the third through hole 341 of the fastener 34 to extend into the locking groove 113. The abutment post 52 can drive the locking arm 51 to extend into or retract from the locking groove 113.

[0053] Furthermore, the two ends of the second elastic element 80 abut against the bottom wall of the fixing hole 331 and the abutment post 52, respectively. In this embodiment, the second elastic element 80 is a spring.

[0054] More specifically, the fastener 34 is screwed into the open end of the fixing hole 331. When the second elastic member 80 is in its naturally extended state, the abutting surface 53 of the locking member 50 abuts against the fastener 34. Thus, the cooperation between the fastener 34 and the abutting surface 53 prevents the locking member 50 from disengaging from the fixing hole 331.

[0055] Furthermore, the mounting block 33 has a clearance groove 332 for avoiding the inclined guide arm 61. The clearance groove 332 is connected to the fixing hole 331, and the inclined guide arm 61 passes through the clearance groove 332 and cooperates with the first inclined guide groove 521. In this embodiment, there are two clearance grooves 332 corresponding to the inclined guide arm 61.

[0056] In this embodiment, the heat dissipation fin assembly 31 and the mounting block 33 are integrally formed. This arrangement not only facilitates the integration of the locking member 50 and the heat dissipation fin assembly 31, but also simplifies the internal structure of the fill light with a detachable light shield, reduces the number of parts, thereby reducing the size of the fill light with a detachable light shield and increasing its portability.

[0057] The operation process of locking element 50 and unlocking element 60: Please see Figure 12When the pressing block 62 is pressed, the first elastic element 70 is compressed, the inclined guide arm 61 approaches the heat dissipation fin assembly 31, and the inclined guide arm 61 slides along the first inclined guide groove 521 to drive the abutment post 52 to compress the second elastic element 80. At the same time, the locking arm 51 exits the locking groove 113.

[0058] Please see Figure 10 When the pressing block 62 is released, the first elastic element 70 extends, and the inclined guide arm 61 gradually moves away from the heat dissipation fin assembly 31. Under the pushing action of the second elastic element 80, the abutting post 52 drives the locking arm 51 to extend into the locking groove 113.

[0059] Please see Figure 8 and Figure 9 The end of the inclined guide arm 61 is provided with a first inclined guide surface 611, and the first inclined guide groove 521 has a second inclined guide surface 522 that cooperates with the first inclined guide surface 611. The cooperation of the first inclined guide surface 611 and the second inclined guide surface 522 can make the contact between the inclined guide arm 61 and the first inclined guide groove 521 smoother, thereby improving the user experience, and can also slow down the wear rate between the inclined guide arm 61 and the abutment post 52, thereby improving durability.

[0060] Furthermore, the tilt angle of the first inclined guide surface 611 is the same as the tilt angle of the second inclined guide surface 522. This arrangement helps to further increase the smoothness of the locking member 50 and the unlocking member 60, as well as enhance the durability of the locking member 50 and the unlocking member 60.

[0061] Furthermore, the end of the locking arm 51 is provided with a third inclined guide surface 511 for abutting against the protrusion 41. The provision of the third inclined guide surface 511 improves the convenience for the user to install the sunshade 40. When installing the sunshade 40, the user does not need to press the unlocking member 60 to make the locking arm 51 disengage from the locking groove 113.

[0062] More specifically, when the light shield 40 is installed in the mounting slot 11, the user first aligns the body of the light shield 40 with the annular slot 111 and the protrusion 41 with the mating slot 112, then inserts the light shield 40 and rotates it so that the protrusion 41 on it approaches the locking slot 113; at this time, the protrusion 41 abuts against the third inclined guide surface 511, and the protrusion 41 drives the locking arm 51 to gradually exit the locking slot 113 by abutting against the third inclined guide surface 511; after the protrusion 41 enters the locking slot 113, the locking arm 51 extends out of the locking slot 113 again to achieve the locking effect of the light shield 40.

[0063] Please see Figure 3 A chamfered structure 14 is provided at the connection between the mating groove 112 and the surface of the housing 10. The chamfered structure 14 allows the protrusion 41 to slide smoothly into the mating groove 112, improving the smoothness of the sunshade 40 when it is placed into the mounting groove 11, thereby enhancing the user experience.

[0064] In addition, the supplementary light with a detachable light shield also includes a control module and a power module. The control module is used to precisely adjust the output of the light source 20, such as brightness and color temperature, and to realize the coordinated operation of the power module and the heat dissipation module 30. The power module is used to efficiently convert and distribute electrical energy to ensure stable power supply and instantaneous high power demand.

[0065] The installation process of the light shield 40 of the supplementary light with a detachable light shield in this embodiment is as follows: (1) Please refer to Figure 10 Place the light shield 40: Align the body of the light shield 40 with the annular groove 111 and the protrusion 41 with the mating groove 112, and then place the light shield 40 into it.

[0066] (2) Please refer to Figure 11 and Figure 12 Locking the sunshade 40: Rotate the sunshade 40 so that the protrusion 41 on it approaches the locking groove 113. The protrusion 41 abuts against the third inclined guide surface 511. The protrusion 41 drives the locking arm 51 to gradually exit the locking groove 113 by abutting against the third inclined guide surface 511. When the protrusion 41 is fully inserted into the locking groove 113, the locking arm 51 extends out of the locking groove 113 again to achieve the locking effect of the sunshade 40.

[0067] Please see Figure 13 The disassembly process of the light shield 40 of the supplementary light with a detachable light shield in this embodiment is as follows: (1) Release the lock of the light shield 40: Press the pressing block 62, the first elastic element 70 is compressed, the inclined guide arm 61 approaches the heat dissipation fin group 31, the inclined guide arm 61 slides along the first inclined guide groove 521 to drive the abutment post 52 to compress the second elastic element 80, at the same time, the abutment post 52 drives the locking arm 51 to exit the locking groove 113.

[0068] (2) Remove the sunshade 40: Press the pressing block 62 continuously and rotate the sunshade 40 in the opposite direction to disengage the protrusion 41 from the locking groove 113. At this time, the protrusion 41 is located in the mating groove 112; stop pressing the pressing block 62 and remove the sunshade 40.

[0069] The advantages of this utility model of a supplementary light with a detachable light shield are as follows: (1) It can be installed, locked and removed from the light shield 40. (2) It has good reliability and durability.

[0070] (3) Integrating the locking part 50 with the heat dissipation fin assembly 31 helps to simplify the internal structure of the fill light with a detachable light shield, reduce the number of parts, thereby reducing the size of the fill light and increasing its portability.

[0071] (4) During the disassembly process, the pressing block 62 must be pressed continuously and the sunshade 40 must be rotated simultaneously to achieve disassembly, so as to prevent the sunshade 40 from being accidentally unlocked and falling off.

[0072] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
