Description

Technical Field

[0001] This application relates to the field of camera technology, and more particularly to a self-locking quick-release connection structure for a camera device. Background Technology

[0002] As users' demands for photography increase, the pixel count of mobile phone lenses is constantly improving, aiming to replace cameras as professional photography equipment. However, mobile phones have limited expansion functions. Therefore, when using a mobile phone for shooting, auxiliary tools such as a camera cage are usually connected to the phone. Then, a fill light, microphone, etc. are installed on one side of the camera cage to improve the shooting effect of the mobile phone.

[0003] In existing products, the rabbit cage has a handle installed on at least one side. Therefore, when taking pictures with a mobile phone, people usually hold the handle with their hands to enhance the shooting feel and reduce the shaking of the shooting image caused by hand tremors or movement. However, the existing handles usually need to be installed in the rabbit cage in a complicated way, which results in low installation efficiency. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] The following is a reference to the appendix. Figures 1 to 6 The specific embodiments of this application will be described in further detail below.

[0044] Reference Figure 1 This application provides a self-locking quick-release connection structure 100, which can combine electronic products and photography auxiliary tools, and make the electronic products stable to be held or placed on a support surface, thereby enhancing the stability and flexibility of the electronic products during shooting. In this embodiment, the electronic products can be photography equipment such as mobile phones and cameras.

[0045] The self-locking quick-release connection structure 100 includes a first mounting member 10 and two second mounting members 30. The first mounting member 10 is used to mount electronic products and photography auxiliary tools. The second mounting members 30 are detachably connected to the first mounting member 10 and are located on one side of the first mounting member 10. The first mounting member 10 and the second mounting member 30 are components used in conjunction with each other. In this embodiment, the first mounting member 10 is an auxiliary component such as a rabbit cage for mounting electronic products and photography auxiliary tools, and the second mounting member 30 is a handle mounted on the bottom or side of the rabbit cage; or, the first mounting member 10 is an auxiliary component such as a backpack clip for mounting electronic products, then the second mounting member 30 is an adapter mounted on one side of the backpack clip, and the photography auxiliary product is connected to the adapter. This embodiment is described in detail with the first mounting member 10 as a rabbit cage and the second mounting member 30 as a handle.

[0046] Reference Figure 1 The first mounting component 10 is a square frame with an internal receiving space. A magnetic element is installed on one side of the square frame protruding towards the center. Electronic products such as mobile phones are installed in the receiving space of the first mounting component 10 through the magnetic element. Alternatively, fasteners are provided on the frame of the first mounting component 10, and the camera is fixed in the first mounting component 10 through the fasteners. A connecting groove is installed on one side of the square frame for connecting auxiliary photography tools such as fill lights and microphones.

[0047] Reference Figure 2 and Figure 3 The first mounting member 10 has a recessed insertion groove 11 on one side. The insertion groove 11 is arc-shaped, and the opening size at both ends is smaller than the opening size in the middle, so that one end of the second mounting member 30 can be inserted. Simultaneously, insertion holes 13 are formed through the two opposite inner sidewalls of the insertion groove 11. The two insertion holes 13 are respectively connected to the insertion groove 11. In this embodiment, the insertion holes 13 and the insertion groove 11 have a stepped structure, and the bottom surface of the insertion groove 11 is lower than the bottom surface of the insertion holes 13. The insertion holes 13 and the insertion groove 11 cooperate to form a snap-fit ​​surface 15 (see reference). Figure 4 Promotion Department.

[0048] The second mounting member 30 is mounted on the first mounting member 10 as a handle. The second mounting member 30 includes a locking member and an unlocking member 80. One end of the locking member is detachably inserted into the insertion slot 11, and a portion of the locking member protrudes and is inserted into the insertion hole 13, so that the second mounting member 30 is mounted on the first mounting member 10, and the second mounting member 30 is in a locked state. The unlocking member 80 drives a portion of the locking member, so that a portion of the locking member is disengaged from the insertion hole 13, and the second mounting member 30 is in an unlocked state, and the first mounting member 10 can be detached from the second mounting member 30.

[0049] The locking mechanism includes a body 50, a transmission component 60, and two locking pins 70. The unlocking component 80 is slidably fitted onto one end of the body 50. The transmission component 60 is retractably housed within the body 50 and partially protrudes from one end of the body 50, and can elastically extend and retract relative to the body 50. The two locking pins 70 are movably mounted inside the transmission component 60.

[0050] Reference Figure 3 and Figure 4 The main body 50 is a hollow, elongated structure with a receiving groove 501 inside. The receiving groove 501 is a recessed structure with an opening on one side, used to receive the transmission component 60 and two locking pins 70. The main body 50 includes an integrally formed fixing part 51, a connecting part 53, and a handle part 55. The connecting part 53 is located between the fixing part 51 and the handle part 55, and the three parts are arranged in a stepped shape.

[0051] The fixing part 51 is cylindrical and has two oppositely arranged through holes 511 in the X-axis direction. The through holes 511 and the receiving groove 501 are interconnected. Each through hole 511 corresponds to the position of a locking pin 70 and is used to insert a locking pin 70.

[0052] The connecting portion 53 is square in shape and is slidably connected to the unlocking member 80. The connecting portion 53 has two opposing strip-shaped holes 531 along the Z-axis. A portion of the unlocking member 80 is inserted into the strip-shaped holes 531 and can slide within them, separating the first mounting member 10 and the second mounting member 30 after engagement. The strip-shaped holes 531 communicate with the receiving groove 501 and are located below the through hole 511.

[0053] The handle portion 55 is for the user to hold. In some embodiments, a connector (not shown) is also mounted on the handle portion 55 for connecting photographic auxiliary tools such as a monitor. Understandably, in some embodiments, the handle portion 55 is provided with anti-slip features such as anti-slip textures.

[0054] The transmission component 60 includes a main body 61 and an elastic element 63. The main body 61 and the elastic element 63 are together housed within a receiving groove 501, with the elastic element 63 fixedly clamped between the bottom surface of the receiving groove 501 and the bottom surface of the main body 61. When the elastic element 63 is in its initial state, a portion of the main body 61 is supported by the elastic element 63 and partially protrudes outside the receiving groove 501. When the elastic element 63 is in a compressed state, the main body 61 is driven to be housed within the receiving groove 501.

[0055] Reference Figure 4The main body 61 is cylindrical, and mounting grooves 611 are recessed along the X-axis on two opposite outer walls of the main body 61. Each mounting groove 611 is strip-shaped and corresponds to and communicates with the through hole 511 of the fixing part 51, so that one end of each locking pin 70 is installed in the mounting groove 611, and the other end passes through the through hole 511 and slides within the mounting groove 611. Each mounting groove 611 has an open groove structure on one side, and the opening direction (Z direction) of the mounting groove 611 is perpendicular to the length (Y direction) of the main body 61.

[0056] The recessed depth in the middle of the mounting groove 611 is less than the recessed depth at both ends. When the two locking pins 70 are located in the middle of the mounting groove 611, a portion of the two locking pins 70 protrudes from the through hole 511. At the same time, the first mounting member 10 and the second mounting member 30 are connected to each other and locked. When the two locking pins 70 are located at either end of the mounting groove 611, the locking pin 70 is completely received in the through hole 511 and the mounting groove 611, and the first mounting member 10 and the second mounting member 30 are in the unlocked or initial state.

[0057] Each mounting slot 611 has a first magnetic attraction part 65, a pushing part 67, and a second magnetic attraction part 69 on its bottom surface. The pushing part 67 is located between the first magnetic attraction part 65 and the second magnetic attraction part 69, and is positioned in the middle of the mounting slot 611, dividing the mounting slot 611 into a first recess and a second recess by the pushing part 67. The first magnetic attraction part 65 is mounted on the bottom surface of the first recess, and the second magnetic attraction part 69 is mounted on the bottom surface of the second recess. Both the first magnetic attraction part 65 and the second magnetic attraction part 69 are magnetic. In the X-axis direction, the height of the pushing part 67 is greater than the height of the first magnetic attraction part 65 and the second magnetic attraction part 69.

[0058] The two pushing parts 67 have hexagonal cross-sections, and each pushing part 67 includes a first guide surface 671, a pushing surface 673, and a second guide surface 675. The first guide surface 671 is located near the first magnetic attraction part 65, and the second guide surface 675 is located near the second guide surface 675.

[0059] Reference Figures 4 to 6When part of the main body 61 and the first magnetic part 65 protrude from the main body 50, and the two locking pins 70 are magnetically attracted to both sides of the second magnetic part 69, the elastic member 63 and the second mounting member 30 are both in the initial state. When the two locking pins 70 slide along the second guide surface 675 and are located on the pushing surface 673, the ends of the two locking pins 70 that are far apart from each other protrude from the mounting groove 611 and can be engaged with the engaging surface 15 of the first mounting member 10. Thus, the first mounting member 10 and the second mounting member 30 are engaged with each other and are in a locked state. When the elastic member 63 is compressed under the action of external force, the locking pins 70 move relative to the main body 61 and slide from the pushing surface 673 to the first guide surface 671. At the same time, they are magnetically attracted to both sides of the first guide surface 671. At this time, the second mounting member 30 can be disengaged from the first mounting member 10 and is in an unlocked state. After the external force is removed, the elastic member 63 restores its elastic deformation and pushes the main body 61 towards the main body 61, so that the locking pins 70 slide relative to the main body 61 again and slide from the first guide surface 671 through the pushing surface 673 and are magnetically attracted to the second guide surface 675. At this time, the unlocked state switches to the initial state. In this embodiment, the elastic element 63 is a spring. In other embodiments, the elastic element may also be elastic cotton, silicone ring, etc.

[0060] A sliding hole 613 is provided through the side of the main body 61 near the elastic member 63. The sliding hole 613 is strip-shaped, with its two ends defined as end a and end b. The length of the sliding hole 613 along the Y direction is less than that of the strip-shaped hole 531. The sliding hole 613 and the strip-shaped hole 531 are interconnected. In the initial state, only end b of the sliding hole 613 coincides with one end of the strip-shaped hole 531 near the fixing part 51. In the locked state, the strip-shaped hole 531 and the sliding hole 613 are interconnected.

[0061] The unlocking component 80 includes a sliding part 81 and a rod 83 fixedly installed within the sliding part 81. The sliding part 81 is hollow and fitted onto the outer wall of the connecting part 53. Both ends of the rod 83 are fixed to the inner wall of the sliding part 81, and the rod 83 passes through the strip hole 531 of the connecting part 53 and the sliding hole 613 of the main body 61, allowing the sliding part 81 to slide freely within the sliding hole 613 via the rod 83. When the first mounting part 10 and the second mounting part 30 need to be separated after engagement, the unlocking component 80 is pulled towards the end of the slide groove b. At this time, the main body 61 is driven to move relative to the main body 50 towards the handle part 55, the elastic element 63 is compressed, and the main body 61 is driven by the elastic element 63 to move towards the bottom surface of the receiving groove 501 within the main body 50. At this time, the two locking pins 70 slide relative to the main body 61, no longer engaging with the engaging surface 15, but sliding from the pushing surface 673 to the first guide surface 671.

[0062] refer to Figure 4 and Figure 5When using this product, insert the second mounting member 30 in its initial state into the insertion slot 11 of the first mounting member 10, so that one end of the main body 61 abuts against the bottom surface of the insertion slot 11; then, press the main body 61 towards the bottom surface of the insertion slot 11, so that one end of the main body 61 is pressed into the receiving slot 501, and the elastic member 63 is compressed synchronously. At the same time, the two locking pins 70 slide relative to the main body 61. When the locking pins 70 slide from the second magnetic part 69 and pass through the second guide surface 675, and move to the pushing surface 673, the two locking pins 70... When the 0 is pushed by the push surface 673, the two locking pins 70 protrude from the mounting groove 611 and the through hole 511 and are engaged in the engagement surface 15, and cannot continue to slide. At this time, the second mounting part 30 and the first mounting part 10 are engaged and locked. The mobile phone is magnetically attached in the receiving space of the first mounting part 10. Then, the fill light, microphone and other devices are installed on the first mounting part 10 through the connector. By holding the second mounting part 30, stable shooting of people or objects from different angles can be achieved without bending over or squatting.

[0063] refer to Figure 5 and Figure 6 After use, first, take out the mobile phone, microphone, and fill light, etc., and then pull the sliding part 81 towards the handle part 55, so that the plug 83 moves along the b end of the sliding hole 613, the elastic element 63 is compressed, and the main body 61 is moved synchronously. The two locking pins 70 slide from the pushing surface 673 along the first guide surface 671 to the first magnetic part 65 relative to the main body 61. At this time, one end of the locking pin 70 is magnetically attracted by the first magnetic part 65, and the two locking pins 70 are respectively disengaged from the latching surface 15 and are no longer latched to the latching surface 15. At this time, the second mounting part 30 can be disengaged from the first mounting part 10 and is in the unlocked state. Finally, the second mounting part 30 is pulled out from the first mounting part 10.

[0064] refer to Figure 4 When the user removes the external force applied to the sliding part 81, the elastic element 63 rebounds towards the main body 61 due to its elastic deformation, causing the main body 61 to move towards the first mounting part 10. At this time, the two locking pins 70 disengage from the first magnetic part 65 relative to the main body 61 and are magnetically attracted to the second guide surface 675 after passing through the first guide surface 671, the pushing surface 673, and the second guide surface 675 in sequence. At this time, the unlocked state switches to the initial state. The first mounting part 10 and the second mounting part 30 are then stored away accordingly.

[0065] In this application, the first mounting component 10 and the second mounting component 30 are detachable snap-fit ​​connections. This simple connection method improves installation efficiency, saves storage space, and facilitates storage. In use, simply insert the second mounting component 30 into the first mounting component 10 and press the main body 61. During shooting, holding the second mounting component 30 allows for stable shooting of objects at different angles and heights, improving the flexibility and convenience of the shooting angle. Separating the first mounting component 10 and the second mounting component 30 is also simple; just pull the unlocking component 80 to achieve separation and unlocking. Overall, it is convenient and quick to use.

[0066] Furthermore, the convenient separation of the first mounting component 10 and the second mounting component 30 allows the self-locking quick-release connection structure 100 to be stored separately in different locations when carried, without taking up too much space and thus avoiding space waste.

[0067] The scope of this application is not limited to the foregoing, but is defined by the claims. Therefore, the embodiments described in this specification are merely illustrative and not intended to limit the scope. Thus, all modifications that do not depart from the scope and limits of the claims, as well as content equivalent to the scope and limits of the claims, are included within the scope of the claims.
