Description

Technical Field

[0001] This application relates to the field of camera equipment technology, and in particular to a modularly designed rotating assembly and a flash. Background Technology

[0002] When a camera is used for taking pictures, in environments with poor lighting conditions, a flash is generally needed to supplement the light and meet the lighting requirements for shooting.

[0003] In related technologies, a flash unit includes a light source, a pivot assembly, a rotating assembly, and a control assembly. The light source is disposed on the pivot assembly. The first housing of the pivot assembly is rotatably connected to the second housing of the pivot assembly via the rotating assembly. The pivot assembly can drive the light source to swing vertically to adjust the illumination angle of the light source in the vertical direction. The rotating assembly can drive the pivot assembly to rotate to adjust the illumination angle of the light source in the horizontal direction. Specifically, to achieve a fixed rotation angle, the rotating assembly includes a geared disc and an elastic structure. The geared disc is disposed on the first housing of the pivot assembly, and the elastic structure is disposed on the second housing of the pivot assembly. The elastic structure can extend and retract into a slot of the geared disc. When the pivot assembly rotates relative to the control assembly, the geared disc rotates relative to the elastic structure, and the elastic structure can engage with other slots.

[0004] It should be noted that in order to ensure smooth rotation, lubricating oil and damping oil need to be applied to the gear plate. However, the existing rotating components restrict the flow of lubricating oil and damping oil, causing them to leak easily, which affects the feel of rotation and causes inconsistent rotation feel for each flash. Summary of the Invention

[0043] In the description of this application, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0044] According to the modular design of the rotating assembly 1000 of the first aspect embodiment of this application, it should be noted that, in this embodiment, referring to... Figure 5 and Figure 6 The modular rotating assembly 1000 of this application is applied to a flash lamp, which also includes a light source assembly and a control assembly 3000. The light source assembly is rotatably connected to the control assembly 3000 via the modular rotating assembly 1000, enabling the light source assembly to rotate relative to the control assembly 3000. In other embodiments, the modular rotating assembly 1000 of this application can also be applied between any two objects that need to rotate relative to each other.

[0045] Reference Figures 1 to 4 The modular rotating assembly 1000 of this application includes: a first cover 100, a second cover 200, and a positioning structure 300.

[0046] The second cover 200 is rotatably connected to the first cover 100; it should be understood that one of the first cover 100 and the second cover 200 is fixedly connected to the light source assembly, and the other is connected to the control assembly 3000, thereby enabling the light source assembly and the control assembly 3000 to rotate relative to each other. In this embodiment, refer to... Figure 6 The light source assembly is connected to the first cover 100, and the control assembly 3000 is connected to the second cover 200.

[0047] Reference Figure 2 The positioning structure 300 is disposed between the first cover 100 and the second cover 200; refer to Figure 3 The positioning structure 300 includes an elastic element 310 and a positioning part 320. The positioning part 320 is disposed on the first cover 100, and the elastic element 310 is disposed on the second cover 200. Multiple slots 321 are formed on the periphery of the positioning part 320. The elastic element 310 slides with the periphery of the positioning part 320, allowing it to engage in any slot 321. It should be understood that, since the positioning part 320 and the elastic element 310 are respectively disposed on the first cover 100 and the second cover 200, when the first cover 100 and the second cover 200 rotate relative to each other, the positioning part 320 can rotate relative to the elastic element 310, and the elastic element 310 can slide on the periphery of the positioning part 320, allowing it to engage in different slots 321. Specifically, the end of the elastic member 310 is engaged in the slot 321. When the positioning part 320 rotates, the elastic member 310 is squeezed by the inner wall of the slot 321 and exits from the slot 321. As the positioning part 320 rotates, the elastic member 310 can slide along the periphery of the positioning part 320 and can be engaged in the next slot 321, thereby allowing the elastic member 310 to switch between any slot 321, thus giving the first cover 100 a sense of shifting when rotating relative to the second cover 200.

[0048] It should be noted that, in order to ensure smooth rotation between the first cover 100 and the second cover 200, and smooth sliding cooperation between the positioning part 320 and the elastic member 310, lubricating oil, damping oil, etc. need to be applied to the positioning part 320. In order to avoid the above-mentioned oil seepage, the dimensions of the first cover 100 and the second cover 200 in the width and length directions are set to be relatively large, and the dimensions of the positioning part 320 in the width and length directions are set to be relatively small. Thus, in the height direction of the modularly designed rotating assembly 1000, the projections of the first cover 100 and the second cover 200 both cover the projection of the positioning part 320. Furthermore, since the positioning part 320 is located between the first cover 100 and the second cover 200, the first cover 100 and the second cover 200 can restrict the flow of oil to prevent oil from leaking out from the positioning part 320, thereby avoiding problems caused by oil leakage, such as poor feel when the first cover 100 and the second cover 200 rotate relative to each other, oil seeping into the control component 3000 causing circuit failure, and oil flowing to the outside of the control component 3000 affecting the appearance.

[0049] Specifically, in this embodiment, the modularly designed rotating assembly 1000 is applied to the flash unit, as shown in the reference... Figure 5When in use, the flash unit is generally positioned with the light source assembly above and the control assembly 3000 below. Therefore, the first cover 100 is positioned above the second cover 200. It should be noted that, under the influence of gravity, there is a possibility of leakage from the positioning part 320. Since the projection of the positioning part 320 falls within the projection of the second cover 200, the second cover 200 blocks the leakage of oil from the positioning part 320, preventing leakage or dripping under gravity. Furthermore, the first cover 100, in conjunction with the second cover 200, further confines the oil to the positioning part 320. In summary, the first cover 100 and the second cover 200 prevent oil leakage from the positioning part 320, ensuring a consistent rotational feel for each modular rotating assembly 1000 and the flash unit using that modular rotating assembly, thus guaranteeing the flash unit's factory quality.

[0050] It should also be noted that in the assembly process of existing flash units, the geared disc of the rotating component needs to be installed onto the shaft assembly first, and the elastic structure of the rotating component needs to be installed onto the control assembly. Then, oil is applied to the geared disc, and the shaft assembly and control assembly are installed, connecting the elastic structure to the geared disc. It should be understood that in the existing assembly method, the connection between the elastic structure and the geared disc during the docking of the shaft assembly and control assembly can easily lead to assembly errors, resulting in inconsistent rotation feel for each flash unit.

[0051] Therefore, it can be understood that the modular design of the rotating component 1000 in this application allows it to be manufactured as an independent standard part. During the assembly of a flash unit using this modular rotating component 1000, only the light source component and control component 3000 need to be installed onto the first cover 100 and the second cover 200, respectively. This facilitates disassembly and assembly, as well as later maintenance and replacement, and reduces the assembly process, thereby reducing assembly errors and ensuring a consistent rotation feel for each flash unit. Furthermore, the rotation feel of the modular rotating component 1000 can be tested directly before assembly, allowing for pre-adjustment without needing to adjust it after the entire flash unit is assembled. If any abnormality is found in the rotation feel of the modular rotating component 1000, it can be adjusted individually.

[0052] Regarding the specific form of the positioning unit 320, in this embodiment, refer to... Figure 1 and Figure 3A groove 321 is formed on the outer peripheral side of the positioning part 320. For example, the positioning part 320 in this application is a toothed disc structure. The elastic member 310 is located beside the outer peripheral side of the positioning part 320. When the first cover 100 and the second cover 200 rotate relative to each other, the elastic member 310 can slide along the outer peripheral side of the positioning part 320. In other embodiments, the positioning part 320 may also form a groove 321 on its inner peripheral side. That is, a through hole is formed in the middle of the positioning part 320, and a groove 321 is formed on the inner wall of the through hole. The elastic member 310 is located in the through hole, and when the first cover 100 and the second cover 200 rotate relative to each other, the elastic member 310 can slide along the inner peripheral side of the positioning part 320.

[0053] For details regarding the rotatable connection between the first cover 100 and the second cover 200, please refer to... Figure 1 and Figure 4 One of the first cover 100 and the second cover 200 is provided with a rotating part 110, and the other has a rotating hole 210. The rotating part 110 passes through the positioning part 320 and rotates in engagement with the rotating hole 210, and the outer peripheral surface of the rotating part 110 is in contact with the inner wall surface of the rotating hole 210. It should be understood that the rotating part 110 can rotate within the rotating hole 210, and the outer peripheral surface of the rotating part 110 can slide relative to the inner wall surface of the rotating hole 210, thereby realizing the relative rotation of the first cover 100 and the second cover 200. Furthermore, the contact between the outer peripheral surface of the rotating part 110 and the inner wall of the rotating hole 210 can play a limiting role, preventing the first cover 100 and the second cover 200 from shaking when rotating relative to each other.

[0054] Specifically, regarding the connection relationship between the rotating part 110 and the positioning part 320, in this embodiment, refer to... Figure 4 A groove 321 is formed on the outer periphery of the positioning part 320. Since the positioning part 320 is disposed between the first cover 100 and the second cover 200, a clearance hole 322 is formed in the middle of the positioning part 320 to allow the rotating part 110 to pass through. That is, the rotating part 110 passes through the positioning part 320 through the clearance hole 322, and the outer periphery of the positioning part 320 is in contact with the inner wall surface of the clearance hole 322 to limit the positioning part 320. In other embodiments, for example, to achieve a fixed connection between the positioning part 320 and the rotating part 110, the positioning part 320 and the rotating part 110 can also be integrally formed; for example, when the groove 321 is formed on the inner periphery of the positioning part 320, the positioning part 320 does not need to be additionally provided with a clearance hole 322, and the rotating part 110 can directly pass through the through hole in the middle of the positioning part 320.

[0055] More specifically, in this embodiment, referring to Figure 4The positioning part 320 and the rotating part 110 are together disposed on the first cover 100, wherein the rotating part 110 and the first cover 100 are integrally formed, and the positioning part 320 is fixedly connected to the first cover 100. It should be understood that when assembling the modular rotating assembly 1000 of this application, the positioning part 320 can be installed on the first cover 100 by first passing the rotating part 110 through the clearance hole 322 of the positioning part 320, and then the second cover 200 is fastened to the first cover 100, which simplifies assembly and improves production efficiency; and the integral forming of the rotating part 110 and the first cover 100 reduces the assembly process and further improves production efficiency. In other embodiments, for example, the positioning part 320 and the rotating part 110 may be respectively disposed on the first cover 100 and the second cover 200, and the positioning part 320 and the rotating part 110 are rotatably connected relative to each other, that is, the rotating part 110 can rotate within the clearance hole 322; for example, the rotating part 110 and the first cover 100 are separately disposed.

[0056] To prevent the rotating part 110 from dislodging from the rotating hole 210, thereby causing the first cover 100 to separate from the second cover 200, therefore, referring to Figure 2 and Figure 4 A limiting part 120 is provided on the rotating part 110, which is used to limit the rotating part 110 from being dislodged from the rotating hole 210.

[0057] Regarding the specific form of the limiting part 120:

[0058] In this embodiment, refer to Figure 2 and Figure 4 The limiting part 120 is a flange, and the end of the rotating part 110 passes through the rotating hole 210. The flange is provided at the end of the rotating part 110 and abuts against the side of the second cover 200 away from the first cover 100.

[0059] It should be understood that the second cover 200 is located between the rotating part 110 and the flange. The flange engages with the rotating part 110 to limit the movement of the second cover 200 in the vertical direction. Since the rotating part 110 is connected to the first cover 100, the outer peripheral surface of the rotating part 110 is in contact with the inner wall surface of the rotating hole 210, thereby restricting the movement of the second cover 200 in the horizontal direction. Thus, the first cover 100 is tightly connected to the second cover 200 through the rotating part 110.

[0060] Specifically, during the assembly of the modular rotating assembly 1000 of this application, after the second cover 200 is installed onto the rotating part 110, that is, after the end of the rotating part 110 passes through the rotating hole 210 of the second cover 200, the end of the second cover 200 is riveted so that the end of the second cover 200 forms a flange, and the flange is pressed against the lower end of the second cover 200, thereby fixing the first cover 100 and the second cover 200 together.

[0061] In other embodiments, the limiting part 120 may also be a nut, and the end of the rotating part 110 is threaded, with the limiting part 120 threadedly connected to the rotating part 110.

[0062] To ensure that the relative rotation of the first cover 100 and the second cover 200 does not affect the wiring connecting the rotating shaft assembly 2000 and the control assembly 3000, refer to... Figure 4 The first cover 100 has a wire hole 140, which passes through the first cover 100 and the rotating part 110, and is used for threading wire.

[0063] To prevent excessive rotation between the first cover 100 and the second cover 200, refer to Figure 1 The modular rotating assembly 1000 of this application also includes a limiting structure for limiting the rotation angle between the first cover 100 and the second cover 200.

[0064] Regarding the specific form of the limiting structure:

[0065] In this embodiment, refer to Figure 1 The limiting structure includes a limiting post 400, which is disposed on the moving path of the elastic member 310. For example, if the limiting post 400 is disposed on the first cover 100, after the first cover 100 rotates relative to the second cover 200 to a certain angle, the elastic member 310 will contact the limiting post 400 to limit the first cover 100 from continuing to rotate; or, for example, the limiting post 400 can also be disposed on the periphery of the rotating part 110.

[0066] In other embodiments, the limiting structure may also be two limiting blocks, which are respectively disposed on the first cover 100 and the second cover 200. After the first cover 100 and the second cover 200 are rotated to a certain angle, the two limiting blocks will contact each other to limit the rotation angle.

[0067] Regarding the specific form of elastic element 310:

[0068] In this embodiment, refer to Figure 1 and Figure 3The elastic element 310 is a torsion spring, which includes a coil 311 and at least two torsion arms 312. The coil 311 is connected to the second cover 200 by a fastener 313. Specifically, the fastener 313 passes through the coil 311 and is fixedly connected to the second cover 200, allowing the coil 311 to swing around the fastener 313. One end of each torsion arm 312 is connected to the coil 311, and the other end can be engaged in a slot 321. At least two torsion arms 312 can be engaged in two different slots 321 simultaneously, and the torsion arms 312 tend to approach the positioning part 320, so that the torsion arms 312 can fit tightly against the positioning part 320 and press against the periphery of the positioning part 320. It should be understood that in this embodiment, there are two torsion arms 312. The two torsion arms 312 provide two contact points between the torsion spring and the positioning part 320, balancing the force on the torsion spring and making the positioning part 320 more stable when rotating relative to the torsion spring.

[0069] In other embodiments, the elastic element 310 may also be a glass bead spring, one end of which is fixed to the second cover 200, and the glass beads of the glass bead spring can be inserted into the slot 321.

[0070] To ensure the rotating part 110 is stably fixed to the first cover 100, refer to Figure 1 The first cover 100 and the positioning part 320 are provided with a positioning post 330 and a positioning hole 130, respectively. The positioning post 330 is inserted into the positioning hole 130, and the positioning post 330 and the positioning hole 130 are either clearance-fitted or tight-fitted.

[0071] In this embodiment, refer to Figure 1 A positioning post 330 is provided on the end face of the positioning part 320 near the first cover 100. The first cover 100 has a positioning hole 130. The positioning post 330 is inserted into the positioning hole 130 to fix the positioning part 320 and the first cover 100 relatively. There are multiple positioning posts 330 and positioning holes 130, and they correspond one-to-one. The positioning post 330 is clearance-fitted with the positioning hole 130, and the upper end of the positioning post 330 extends out of the positioning hole 130. In order to make the connection between the positioning part 320 and the first cover 100 tighter, part or all of the portion of the positioning post 330 extending out of the positioning hole 130 is flattened by heat pressing, so that the positioning post 330 abuts against the wall of the positioning hole 130, thereby making part or all of the positioning post 330 tightly fitted with the positioning hole 130.

[0072] In other embodiments, for example, the positioning part 320 may also be provided with a positioning hole 130, and the first cover 100 may be provided with a positioning post 330; for example, all the positioning posts 330 may be in clearance fit with the positioning hole 130, or they may be in tight fit with the positioning hole 130.

[0073] In this embodiment, the positioning part 320 is made of POM or nylon material, and its surface is textured to provide a certain amount of friction and damping when the positioning part 320 slides with the elastic element 310. The second cover 200 is made of stainless steel, which has high strength and is not easily deformed.

[0074] Reference Figures 5 to 8 A flash unit according to a second aspect embodiment of this application includes: a light source assembly, a control assembly 3000, and a modularly designed rotating assembly 1000 according to the first aspect embodiment. The light source assembly is connected to a first cover 100. The control assembly 3000 is connected to a second cover 200.

[0075] The flash lamp according to the second aspect embodiment of this application has at least the following beneficial effects: including all the beneficial effects of the modular design of the rotating assembly 1000 of the first aspect embodiment, which will not be repeated here.

[0076] In this embodiment, refer to Figure 5 and Figure 6 The light source assembly includes a rotating shaft assembly 2000 and a light source. The light source is located at the movable end of the rotating shaft assembly 2000, and the rotating shaft assembly 2000 can drive the light source to swing vertically. In other embodiments, the light source assembly may not have a rotating shaft assembly 2000 and may only include the light source.

[0077] It is understood that, in this embodiment, reference is made to... Figure 6 The first housing 500 of the rotating shaft assembly 2000 is rotatably connected to the second housing 600 of the rotating shaft assembly 2000 through the rotating component 1000 of the modular design of this application, so that the rotating shaft assembly 2000 can rotate relative to the control component 3000.

[0078] The first outer shell 500 is threadedly connected to the first cover 100 by screws.

[0079] The second outer shell 600 is snapped into the second cover 200, specifically, refer to... Figure 7 The second cover 200 is fitted inside the second outer shell 600, with its upper surface abutting against the inner wall of the second outer shell 600. At least two fixing ribs 620 are provided on the inner wall of the second outer shell 600, abutting against the side of the second cover 200. The second outer shell 600 has a mounting hole 610, and the positioning structure 300 is located within the mounting hole 610. Because the depth of the mounting hole 610 matches the height of the positioning structure 300, the lower surface of the first cover 100 abuts against the outer wall of the second outer shell 600, thereby achieving the connection between the rotating shaft assembly 2000 and the second outer shell 600.

[0080] It should be noted that in this embodiment, the size of the second cover 200 is larger than the size of the first cover 100. Therefore, in order to facilitate the screw tightening during the threaded connection between the first cover 100 and the first outer shell 500, refer to... Figure 1 The second cover 200 has a through hole 220.

[0081] And, in order to facilitate the insertion of the second cover 200 into the control component 3000, refer to Figure 8 The second outer shell 600 includes a first shell 630 and a second shell 640. Both the first shell 630 and the second shell 640 have notches. The notches of the first shell 630 and the second shell 640 are joined together to form a mounting hole 610.

[0082] Therefore, the installation process of the modular rotating assembly 1000 of this application can be as follows: align the threaded hole on the first cover 100 with the threaded hole on the first housing 500, and then pass the screw through the through hole 220 through the threaded hole on the first cover 100 and the threaded hole on the first housing 500 to fix the rotating shaft assembly 2000 on the first cover 100. Then, the notch of the first housing 630 and the notch of the second housing 640 are aligned with the positioning structure 300. The first housing 630 and the second housing 640 are interlocked to form a mounting hole 610. The positioning structure 300 is located in the mounting hole 610. The lower end face of the first cover 100 and the upper end face of the second cover 200 are respectively in close contact with the outer side wall and the inner side wall of the second housing 600, so that the first cover 100 and the second cover 200 clamp the second housing 600. The second cover 200 is located between the fixing ribs 620 and abuts against the fixing ribs 620, thereby completing the connection between the control component 3000 and the modularly designed rotating component 1000 of this application, so as to complete the assembly of the rotating shaft component 2000, the modularly designed rotating component 1000, and the control component 3000.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
