Technical Field

[0001] The present application relates to the technical field of annular light sources, and in particular to a highly applicable annular light source installation structure and a method of using the same. Background Art

[0002] As a specially designed light source, the ring light source is composed of a high-density LED array. It can provide uniform and stable lighting, so it can highlight the three-dimensional information of the illuminated object through precise optical structure design, reduce the shadow problem caused by multi-directional lighting, and capture high-quality images. Therefore, it plays an important role.

[0003] There is a ring light source in the prior art, which includes a ring housing, a PCB board and a plurality of light sources. The PCB board is arranged in a chamber of the ring housing and is fixedly connected to the ring housing. The side wall of the PCB board is arranged obliquely and is ring-shaped. The plurality of light sources are mounted on the PCB board. When in use, the PCB board provides power and signal control for the light sources, so that the plurality of light sources emit light along a specific angle.

[0004] With regard to the above-mentioned related technologies, since the PCB board in the prior art is fixedly connected to the annular shell and the inclination angle of the side wall of the PCB board is fixed, when the illumination angle of the annular light source needs to be adjusted, the relevant personnel need to disassemble the annular light source and replace it with a new annular light source with another PCB board with a different inclination angle, which increases the replacement cost and needs to be improved. Summary of the invention

[0005] In order to reduce the replacement cost when adjusting the irradiation angle of the ring light source, the present application provides a highly applicable ring light source installation structure and a method of using the same.

[0006] In a first aspect, the present application provides a highly applicable ring light source installation structure, which adopts the following technical solution: A highly applicable annular light source installation structure comprises an annular shell and a PCB board. A plurality of positioning grooves are provided on the inner wall of the annular shell, and the plurality of positioning grooves are distributed along the axial direction of the annular shell. A positioning ring and a fixing ring are also provided on the annular shell. One end of the PCB board abuts against the inner wall of a corresponding positioning groove, and the other end abuts against one side of the positioning ring. The positioning ring is provided on the fixing ring, and the fixing ring is detachably connected to the annular shell.

[0007] By adopting the above technical scheme, compared with the prior art, relevant personnel need to disassemble the annular light source and replace it with a new annular light source with a PCB board with a different inclination angle in order to adjust the illumination angle of the annular light source, thereby increasing the replacement cost; the present application arranges the positioning ring and the fixing ring, so that when the illumination angle of the annular light source needs to be adjusted, the relevant personnel only need to disassemble the fixing ring and the positioning ring, and then select PCB boards with different inclination angles and positioning rings of different thicknesses, and place the replaced PCB board and positioning ring in the annular shell, and make one end of the PCB board abut against the inner wall of the corresponding positioning groove, and the other end abut against the positioning ring, and then install the fixing ring on the annular shell, so as to realize the replacement of the PCB board, and then there is no need to replace the entire annular light source, which effectively saves the replacement cost.

[0008] Preferably, the positioning ring is slidably connected to the annular shell, and the sliding direction is the axial direction of the annular shell. An adjustment mechanism is also provided on the annular shell, and the adjustment mechanism includes an adjustment component and a locking component. The adjustment component is used to push the positioning ring to slide, and the locking component is used to lock the positioning ring after the positioning ring slides.

[0009] By adopting the above technical solution and setting the adjustment mechanism, relevant personnel can drive the positioning ring to slide through the adjustment component, so that the positioning ring can be abutted against the replaced PCB board and locked by the locking component after abutment, thereby eliminating the need to replace positioning rings of other specifications, effectively saving replacement costs and facilitating replacement for relevant personnel.

[0010] Preferably, the adjustment assembly includes an adjustment frame, which is slidably connected to the annular shell, and the sliding direction is the same as the sliding direction of the positioning ring. One end of the adjustment frame abuts against an end of the positioning ring close to the fixed ring, and the locking assembly is used to lock the adjustment frame after the adjustment frame slides.

[0011] By adopting the above technical solution, the adjustment frame is set up so that the adjustment frame can abut against the positioning ring and push the positioning ring to slide, thereby making the positioning ring abut against the PCB board, and then together with the inner wall of the positioning groove, the PCB board is fixed, which effectively facilitates the relevant personnel to adjust the position of the positioning ring, thereby facilitating the relevant personnel to replace the PCB board.

[0012] Preferably, the locking assemblies are provided in plurality, and the plurality of locking assemblies are distributed along the axis of the annular shell, and each of the locking assemblies comprises a locking frame and an elastic member, and each of the locking frames is slidably connected to the annular shell, and the sliding direction is perpendicular to the sliding direction of the adjusting frame, and a side of the locking frame close to the fixing ring is abutted against a side of the adjusting frame away from the fixing ring.

[0013] By adopting the above technical solution and setting the locking assembly, when the adjusting frame slides to the specified position, the corresponding locking frame can abut against the side of the adjusting frame away from the abutting assembly, thereby preventing the locking frame from sliding in the direction away from the PCB board, thereby locking the adjusting frame, and locking the positioning ring by locking the adjusting frame, which effectively facilitates the operation of relevant personnel.

[0014] Preferably, the adjustment assembly also includes an unlocking frame, which is slidably connected to the adjustment frame, and the sliding direction is perpendicular to the sliding direction of the locking frame. The locking frame locks the adjustment frame by abutting against the unlocking frame. An unlocking groove is provided on one surface of the unlocking frame. The unlocking groove is used to correspond to the corresponding locking frame after the unlocking frame slides, so that the corresponding locking frame can pass through.

[0015] By adopting the above technical solution, the unlocking frame is set so that the locking frame can resist the unlocking frame, thereby hindering the sliding of the adjusting frame, and then locking the adjusting frame. At the same time, the existence of the unlocking groove makes it possible for the unlocking groove to gradually move to a position corresponding to the corresponding locking frame when the unlocking frame slides relative to the adjusting frame, so that the locking frame can unlock the unlocking frame and the adjusting frame through the unlocking groove, which effectively facilitates relevant personnel to unlock the unlocking frame.

[0016] Preferably, one end of the adjustment frame extends out of the annular shell, and a protective cover is provided outside the annular shell. The end of the adjustment frame extending out of the annular shell is located inside the protective cover, and the protective cover is sleeved outside the annular shell and rotatably connected to the annular shell.

[0017] By adopting the above technical solution, the protective cover is set so that the protective cover can protect the adjusting frame, thereby reducing the probability of damage to the end of the adjusting frame extending out of the annular shell, effectively ensuring the service life of the adjusting frame. At the same time, after the protective cover is rotated, the adjusting frame can be exposed outside the protective cover, so that relevant personnel can move the adjusting frame normally.

[0018] Preferably, the adjustment mechanism also includes a driving assembly, which includes a connecting frame and a sliding frame, one end of the connecting frame is rotationally connected to the sliding frame, and the other end is rotationally connected to the protective cover, the sliding frame is slidingly connected to the annular shell, and the sliding direction is the same as the sliding direction of the unlocking frame, and the unlocking frame is located on the sliding path of the sliding frame.

[0019] By adopting the above technical solution and setting the driving component, when the protective cover rotates, the protective cover can drive one end of the connecting frame to move together, and make the end rotate relative to the protective cover, so that the other end of the connecting frame can be displaced, thereby driving the sliding frame to slide, and making the sliding frame gradually resist against the unlocking frame, pushing the unlocking frame to slide, thereby realizing the driving of the unlocking frame, and effectively facilitating the operation of relevant personnel.

[0020] Preferably, a limiting mechanism is also provided in the annular shell, and the limiting mechanism includes a limiting frame and a linkage assembly. The limiting frame is slidably connected to the annular shell, and the sliding direction is the axial direction of the annular shell. A plurality of limiting parts are also extended from the limiting frame, and the limiting parts correspond to the locking assembly. One of the limiting parts is inserted in the unlocking groove, and the sliding frame drives the limiting frame to slide through the linkage assembly so that the limiting part is disengaged from the unlocking groove.

[0021] By adopting the above technical solution and setting the limit mechanism, the limit frame can be inserted into the unlocking groove, thereby preventing the unlocking frame from accidentally slipping, effectively ensuring that the locking assembly locks the unlocking frame. At the same time, when the protective cover rotates, the protective cover can drive the limit frame to slide through the sliding frame and the linkage assembly, thereby releasing the limit on the unlocking frame and realizing the linkage between the sliding frame and the protective cover, which effectively facilitates the operation of relevant personnel.

[0022] Preferably, the linkage assembly includes a linkage gear and two linkage racks, one of the linkage gears is connected to the sliding frame, and the other linkage gear is connected to the limiting frame, each of the linkage racks is meshed with the linkage gear, and the linkage gear is rotatably connected to the annular shell.

[0023] By adopting the above technical solution and the specific setting of the linkage assembly, the sliding frame can drive the linkage gear to rotate through the linkage rack when sliding, so that the other linkage rack can slide, thereby driving the sliding of the limit frame, thereby realizing the linkage between the sliding frame and the limit frame, and effectively facilitating the operation of relevant personnel.

[0024] On the other hand, the present application also provides a method for using a highly applicable ring light source installation structure, which comprises the following steps: Placing the PCB board: After selecting a PCB board of appropriate size and specification, place the PCB board in the chamber of the annular housing; Positioning the PCB board: placing the end of one end of the PCB board in the corresponding positioning groove and abutting against the inner wall of the corresponding positioning groove, and then making the other end of the PCB board abut against the inner wall of the annular housing; Place the positioning ring: select a positioning ring of appropriate thickness and sleeve the positioning ring into the chamber of the annular housing so that one side of the positioning ring abuts against the end of the PCB board, thereby positioning the PCB board; Install the fixing ring: install the fixing ring on the end of the annular housing through the connecting piece, and make the fixing ring abut against the positioning ring to fix the positioning ring and the PCB board.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The positioning ring and the fixing ring are set so that when the irradiation angle of the ring light source needs to be adjusted, the relevant personnel only need to remove the fixing ring and the positioning ring, and then select PCB boards with different inclination angles and positioning rings of different thicknesses, and place the replaced PCB boards and positioning rings in the ring housing, and make one end of the PCB board abut against the inner wall of the corresponding positioning groove, and the other end abut against the positioning ring, and then install the fixing ring on the ring housing, so that the PCB board can be replaced, and there is no need to replace the entire ring light source, which effectively saves the cost of replacement; 2.

[0034] Reference Figure 1 and Figure 2 In the embodiment of the present application, each positioning groove 11 is configured as a circular groove and is coaxially arranged with the annular housing 1. Each positioning groove 11 is opened on the inner wall of the chamber of the annular housing 1 facing the fixing ring 4. A plurality of positioning grooves 11 are arranged in communication so that the plurality of positioning grooves 11 are stepped, and the diameter of the positioning groove 11 closer to the axis of the annular housing 1 is larger, so that the end of the PCB board 2 can smoothly abut against the inner wall of the positioning groove 11.

[0035] Referring to the figure, the PCB board 2 is an inclined circular ring, and the end of the PCB board 2 along its own axis and with a smaller inner diameter is against the inner wall angle of the corresponding positioning groove 11 to increase the stability of the PCB board 2. The other end of the PCB board 2 is against one side of the positioning ring 3, and the outer wall of the positioning ring 3 is set against the inner wall of the annular housing 1. In the embodiment of the present application, one annular housing 1 can match PCB boards 2 with various inclination angles and positioning rings 3 with various thicknesses, so as to facilitate the replacement of relevant personnel.

[0036] Reference Figure 1 and Figure 2 The side of the positioning ring 3 away from the PCB board 2 is coplanar with the end of the annular housing 1. The fixing ring 4 is located on the side of the positioning ring 3 away from the PCB board 2, and the side of the positioning ring 3 away from the PCB board 2 and the end of the annular housing 1 are both against one side of the fixing ring 4, thereby fixing the positioning ring 3. The fixing ring 4 is detachably connected to the annular housing 1 by a plurality of screws, so that relevant personnel can easily remove and install the fixing ring 4.

[0037] The implementation principle of the highly applicable annular light source installation structure of the first embodiment of the present application is as follows: when the PCB board 2 needs to be replaced, the fixing ring 4 is first removed, and then the positioning ring 3 and the PCB board 2 are removed. Next, one end of the PCB board 2 to be replaced is placed in the corresponding positioning groove 11, and the end of the PCB board 2 is abutted against the angle of the positioning groove 11, and then the other end of the PCB board 2 is abutted against the inner side wall of the annular housing 1.

Install the fixing ring: Use a number of screws to install the fixing ring 4 on the end of the annular housing 1 , and make the fixing ring 4 fit against the positioning ring 3 , so as to fix the positioning ring 3 and the PCB board 2 .

[0040] Embodiment 2: The difference between the second embodiment of the present application and the first embodiment is that: Figure 3 and Figure 4The outer side of the positioning ring 3 also extends outwardly with a plurality of sliding parts 31, and the plurality of sliding parts 31 are distributed at equal angles along the circumference of the axial direction of the positioning ring 3. The end of each sliding part 31 is embedded in the inner side wall of the annular housing 1 and is slidably connected to the annular housing 1, and the sliding direction is the axial direction of the annular housing 1.

[0041] Reference Figure 3 and Figure 4 The annular housing 1 is also provided with an adjustment mechanism 5, and the adjustment mechanism 5 includes an abutment assembly 51, an adjustment assembly 52 and a locking assembly 53. In the embodiment of the present application, a plurality of abutment assemblies 51 are provided, and are provided one-to-one with the sliding portion 31. Each abutment assembly 51 includes a guide rod 511 and an abutment spring 512, and one end of each guide rod 511 is fixedly connected to the inner wall of the annular housing 1. The axial direction of each guide rod 511 is the sliding direction of the positioning ring 3.

[0042] Referring to 4, the other end of each guide rod 511 passes through the corresponding sliding part 31 and is slidably connected with the corresponding sliding part 31. Each sliding part 31 is provided with a through slot for the corresponding guide rod 511 to pass through. Each abutment spring 512 is sleeved on the corresponding guide rod 511. Each abutment spring 512 is located on the side of the positioning ring 3 away from the fixing ring 4, and one end of each abuts against the inner wall of the annular shell 1, and the other end of each abuts against the corresponding sliding part 31, so that the positioning ring 3 can return to the initial position under the elastic force of the abutment spring 512, thereby facilitating the disassembly of relevant personnel.

[0043] Reference Figure 4 and Figure 5 In the embodiment of the present application, the number of the adjustment components 52 is set to two, and the two adjustment components 52 are respectively located on opposite sides of the positioning ring 3. Each adjustment component 52 includes an adjustment frame 521, an unlocking frame 522 and a return spring 523. Each adjustment frame 521 is located on a side of the corresponding sliding portion 31 away from the abutment spring 512, and is slidably connected to the inner wall of the annular housing 1, and the sliding direction is the axial direction of the annular housing 1.

[0044] Reference Figure 3 and Figure 4 Each adjustment frame 521 abuts against the corresponding sliding portion 31, so that the adjustment frame 521 can push the positioning ring 3 to slide. In the embodiment of the present application, the end of the adjustment frame 521 abutting against the sliding portion 31 is in a "T" shape and abuts against the inner wall of the annular shell 1 to constrain the adjustment frame 521 so that the adjustment frame 521 can only move along the axial direction of the annular shell 1.

[0045] Reference Figure 3 and Figure 5One end of each adjustment frame 521 extends out of the annular housing 1, so that the relevant personnel can change the position of the positioning ring 3 by moving the adjustment frame 521. One end of each unlocking frame 522 extends into the corresponding adjustment frame 521, and is slidably connected to the corresponding adjustment frame 521, and the sliding direction is the length direction of the corresponding adjustment frame 521.

[0046] Reference Figure 4 and Figure 5 Each return spring 523 is sleeved on the corresponding adjustment frame 521 and is located on the side of the corresponding unlocking frame 522 away from the positioning ring 3. One end of each return spring 523 abuts against the side of the corresponding unlocking frame 522 close to the positioning ring 3, and the other end abuts against the side wall of the corresponding adjustment frame 521, so that the return spring 523 can reset the unlocking frame 522.

[0047] Reference Figure 4 and Figure 5 Each unlocking frame 522 has unlocking grooves 6 on both sides of its top along the width direction. The number of locking components 53 is set to a plurality of groups, and the plurality of groups of locking components 53 are equidistantly distributed along the sliding direction of the adjustment frame 521, so that the plurality of locking components 53 can lock the unlocking frame 522 at multiple positions, so that the unlocking frame 522 and the adjustment frame 521 can be locked at multiple positions. Two locking components 53 are provided in each group, and the two locking components 53 are respectively located on both sides of the unlocking frame 522 along its width direction.

[0048] Reference Figure 4 Each locking assembly 53 includes a locking frame 531 and an elastic member 532. The locking frames 531 are arranged corresponding to the unlocking slots 6, and the locking frames 531 are located on the side of the corresponding unlocking slots 6 away from the adjustment frame 521. One of the locking frames 531 is located below the unlocking frame 522, and the top wall of the unlocking frame 522 abuts against the bottom wall of the unlocking frame 522, thereby locking the unlocking frame 522 and the adjustment frame 521.

[0049] Reference Figure 3 and Figure 4 In the embodiment of the present application, the elastic member 532 is configured as a pressure spring, and each pressure spring is sleeved on one end of the corresponding locking frame 531 away from the unlocking frame 522, and one end is against the corresponding locking frame 531, and the other end is against the inner wall of the annular shell 1, so as to reset the locking frame 531 through its own elastic force.

[0050] Reference Figure 3 and Figure 4Two protective covers 7 are also arranged outside the annular housing 1. The two protective covers 7 are arranged one-to-one with the unlocking frame 522, and each unlocking frame 522 is located in the corresponding protective cover 7. One end of each protective cover 7 is embedded in the outer wall of the annular housing 1 and is rotatably connected to the annular housing 1. An opening is opened on one side wall of each protective cover 7 so that the unlocking frame 522 can be exposed outside the protective cover 7 after the protective cover 7 slides.

[0051] Reference Figure 4 The adjustment mechanism 5 further includes a driving assembly 54, the number of which is set to two and is arranged one-to-one with the protective cover 7. Each driving assembly 54 includes a connecting frame 541 and a sliding frame 542. In the embodiment of the present application, the number of the connecting frames 541 in each driving assembly 54 is set to two, and the two connecting frames 541 are respectively located at both ends of the protective cover 7 along the length direction.

[0052] Reference Figure 3 and Figure 4 One end of each connecting frame 541 is rotatably connected to the corresponding protection cover 7 through a pin, and the other end of each connecting frame 541 is rotatably connected to the corresponding sliding frame 542 through a pin. Each sliding frame 542 is located in the annular housing 1 and is slidably connected to the corresponding annular housing 1, and the sliding direction is the same as the sliding direction of the corresponding unlocking frame 522.

[0053] Reference Figure 4 and Figure 5 Each unlocking frame 522 has an abutting portion 5221 extending outward, and each abutting portion 5221 is integrally formed with the unlocking frame 522. Each abutting portion 5221 is located on the side of the sliding frame 542 away from the positioning ring 3, and is located on the sliding path of the corresponding sliding frame 542, so that when the sliding frame 542 abuts against the abutting portion 5221 during the sliding process, it can push the unlocking frame 522 to slide, so that the unlocking slot 6 on the unlocking frame 522 is displaced to the top of the corresponding locking frame 531, so that the locking frame 531 can unlock the unlocking frame 522 through the unlocking slot 6.

[0054] Reference Figure 4 and Figure 5 In the initial state, the unlocking frame 522 is located in the protective cover 7, and the locking frame 531 abuts against the unlocking frame 522, thereby locking the unlocking frame 522, and the sliding frame 542 is located against the unlocking frame 522. When the protective cover 7 rotates, the protective cover 7 drives the connecting frame 541 to move together, so that the connecting frame 541 drives the sliding frame 542 to slide, so that the sliding frame 542 gradually approaches the abutting portion 5221.

[0055] Reference Figure 4 and Figure 5When the sliding frame 542 abuts against the abutting portion 5221, thereby pushing the unlocking frame 522 to slide, the unlocking slot 6 on the unlocking frame 522 gradually moves to the top of the corresponding locking frame 531, so that the locking frame 531 can unlock the unlocking frame 522 through the unlocking slot 6. In this process, the return spring 523 is gradually compressed, thereby storing elastic potential energy.

[0056] Reference Figure 3 and Figure 4 A limiting mechanism 8 is further provided in the annular housing 1. In the embodiment of the present application, the number of the limiting mechanisms 8 is set to two, and they are arranged one-to-one corresponding to the sliding frames 542. Each limiting mechanism 8 includes a limiting frame 81 and a linkage assembly 82. Each limiting frame 81 is slidably connected to the inner wall of the annular housing 1, and the sliding direction is the axial direction of the annular housing 1.

[0057] Reference Figure 4 and Figure 5 Each limiting frame 81 has a plurality of limiting portions 811 extending outward, and the plurality of limiting portions 811 are arranged one-to-one with the plurality of locking components 53. Each limiting portion 811 is integrally formed with the corresponding limiting frame 81, and one end of each limiting portion 811 away from the limiting frame 81 is bent downward. One limiting portion 811 extends downward into one of the unlocking slots 6 on the unlocking frame 522 to limit the unlocking frame 522 and prevent the unlocking frame 522 from sliding.

[0058] Reference Figure 3 , Figure 4 and Figure 5 Each linkage assembly 82 includes a linkage gear 821 and two linkage racks 822, one linkage rack 822 is fixedly connected to the corresponding sliding frame 542, and the other linkage rack 822 is fixedly connected to the corresponding limiting frame 81. Each linkage gear 821 is rotatably connected to the annular housing 1 through a pin shaft, and each linkage gear 821 is located between the corresponding two linkage racks 822. The two linkage racks 822 are meshed with the corresponding linkage gear 821 to achieve the linkage between the sliding frame 542 and the limiting frame 81.

[0059] Reference Figure 4 and Figure 5 In the initial state, that is, when the unlocking frame 522 is located in the protective cover 7, the corresponding limiting portion 811 on the limiting frame 81 is inserted into the corresponding unlocking slot 6. When the protective cover 7 starts to rotate, the protective cover 7 drives the corresponding sliding frame 542 to slide through the connecting frame 541, so that the sliding frame 542 drives the corresponding limiting frame 81 to slide through the linkage rack 822 and the linkage gear 821, and then the limiting portion 811 on the limiting frame 81 gradually disengages from the unlocking slot 6.

[0060] Reference Figure 3, Figure 4 and Figure 5 When the limiting portion 811 is completely out of the unlocking slot 6, the sliding frame 542 gradually abuts against the abutting portion 5221 on the unlocking frame 522, thereby pushing the abutting portion 5221 to move, causing the unlocking frame 522 to slide, and then causing the unlocking slot 6 on the unlocking frame 522 to gradually move to the position just above the corresponding locking frame 531, thereby unlocking the unlocking frame 522 and the adjusting frame 521. At this time, the unlocking frame 522 is not on the sliding path of the limiting portion 811. Thereafter, under the elastic force of the abutting spring 512, the positioning ring 3 pushes the adjusting frame 521 and the unlocking frame 522 to slide together, thereby causing the positioning ring 3, the adjusting frame 521 and the unlocking frame 522 to be out of the annular housing 1.

[0061] The implementation principle of a highly applicable annular light source installation structure in Example 2 of the present application is as follows: when the PCB board 2 needs to be disassembled, the protective cover 7 is pushed to rotate, and the protective cover 7 drives the corresponding sliding frame 542 to slide through the connecting frame 541, so that the sliding frame 542 drives the corresponding limit frame 81 to slide through the linkage rack 822 and the linkage gear 821, and then the limit part 811 on the limit frame 81 gradually disengages from the unlocking slot 6.

[0062] When the limiting portion 811 is completely separated from the unlocking slot 6, the sliding frame 542 gradually abuts against the abutting portion 5221 on the unlocking frame 522, thereby pushing the abutting portion 5221 to move, causing the unlocking frame 522 to slide, and then causing the unlocking slot 6 on the unlocking frame 522 to gradually move to the position just above the corresponding locking frame 531, thereby unlocking the unlocking frame 522 and the adjusting frame 521. At this time, the unlocking frame 522 is completely displaced to one side of the limiting portion 811. Thereafter, the positioning ring 3, under the elastic force of the abutting spring 512, pushes the adjusting frame 521 and the unlocking frame 522 to slide together, thereby causing the positioning ring 3, the adjusting frame 521 and the unlocking frame 522 to separate from the annular housing 1.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
