Description

Technical Field

[0001] This application relates to the field of shooting auxiliary equipment technology, and in particular to a clamping mechanism and a shooting auxiliary device. Background Technology

[0002] A shooting gimbal has a clamping mechanism for holding shooting devices (such as mobile phones, cameras, etc.). In related technologies, the clamping mechanism usually has a rotation function to enable multi-angle shooting by the shooting gimbal and adapt to the imaging needs of various fields. However, in the shooting gimbals mentioned above, the stability of the clamping mechanism is relatively low, and it is prone to shaking or loosening, which greatly reduces the shooting effect of the shooting gimbal. Utility Model Content

[0003] In view of this, it is necessary to provide a clamping mechanism and a shooting aid to improve the technical problem of poor shooting effect caused by poor stability of the clamping mechanism in existing shooting aids.

[0004] One embodiment of this application provides a clamping mechanism. The clamping mechanism includes a connector, a clamping member, and a locking assembly. The connector is configured to connect to an external support frame. The clamping member has a first surface and a second surface disposed opposite to each other. The first surface is configured to abut against a target object. The clamping member has a mounting portion on the second surface. The mounting portion is rotatably mounted to the connector, allowing the clamping member to rotate relative to the connector. The mounting portion has a plurality of locking slots, which are arranged in a ring around the rotation axis of the clamping member. The locking assembly includes a latch and a pusher that cooperates with the latch. The latch has a first groove and a second groove, and the pusher is configured to move to either the first groove or the second groove. When the pusher is in the first groove, the latch is separated from the groove, and the clamping member can rotate relative to the connector. When the pusher is in the second groove, the latch is engaged in either groove to prevent the clamping member from rotating relative to the connector.

[0005] By engaging the locking tongue and locking groove, the clamping device can be unlocked and locked. The "embedded locking" has a strong locking capability, which helps to reduce the risk of the clamping device shaking or vibrating and improves the shooting effect of the shooting equipment.

[0006] In some embodiments of this application, the sliding direction of the latch intersects with or is parallel to the sliding direction of the pusher.

[0007] In some embodiments of this application, the locking tongue includes a tongue portion and a pressure-receiving portion, with the tongue portion mounted on the pressure-receiving portion. The pressure-receiving portion is slidably mounted on the connector in a direction perpendicular to the rotation axis. The pushing member is slidably mounted on the connector in a direction parallel to the rotation axis. The pressure-receiving portion has a first groove and a second groove, which are spaced apart in a direction parallel to the rotation axis. In a direction perpendicular to the rotation axis, the distance between the bottom of the first groove and the rotation axis is defined as D1, and the distance between the bottom of the second groove and the rotation axis is defined as D2, where D1 < D2.

[0008] In some embodiments of this application, the first groove and the second groove are located on the same side of the tongue along a direction parallel to the rotation axis; or, the first groove and the second groove are located on opposite sides of the tongue along a direction parallel to the rotation axis.

[0009] In some embodiments of this application, the pressure-receiving portion is provided with a first mating surface, the two ends of which are respectively connected to the groove walls of the first groove and the second groove. The pushing member is provided with a second mating surface, which is configured to press the first mating surface when the pushing member moves from the second groove to the first groove, so as to separate the driving tongue from the locking groove.

[0010] In some embodiments of this application, the locking assembly further includes an elastic element installed between the latch and the connecting member. When the pusher moves from the first groove to the second groove, the latch is configured to move towards the axis of rotation under the action of the elastic element and engage in either locking groove.

[0011] In some embodiments of this application, the connector has a receiving cavity and an assembly groove communicating with the receiving cavity. The latch is slidably mounted in the receiving cavity, and the mounting portion is rotatably mounted in the assembly groove. A pusher is mounted on the outer wall of the connector, and a portion of the pusher extends into the receiving cavity and abuts against the latch. When the pusher is in the first groove, the latch retracts into the receiving cavity and separates from the lock groove. When the pusher is in the second groove, the latch extends into the assembly groove and is embedded in either lock groove.

[0012] In some embodiments of this application, the locking tongue has a protrusion, and the connector has a groove in the receiving cavity, with the protrusion slidably installed in the groove.

[0013] In some embodiments of this application, the pusher includes an operating part and an actuating part connected to the operating part. The operating part is configured to be pushed or pulled by a user, and the actuating part is configured to move to a first groove or a second groove under the action of the operating part.

[0014] One embodiment of this application provides a shooting assistance device. The shooting assistance device includes a support frame and a clamping mechanism as described in any of the above embodiments. A connecting member in the clamping mechanism is connected to the support frame.

[0015] The aforementioned shooting assistance device employs the aforementioned clamping mechanism. Through the interlocking of the locking tongue and the locking groove, the clamping component can be unlocked and locked. Furthermore, the "embedded locking" provides strong locking capability, which helps reduce the risk of the clamping component shaking or vibrating, thereby improving the shooting effect of the shooting equipment.

[0031] 20. Support frame. Detailed Implementation

[0032] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0034] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] Please refer to the following: Figure 1 and Figure 2 One embodiment of this application provides a shooting assistance device 100. The shooting assistance device 100 can be a gimbal, selfie stick, etc., and this application does not limit it to this.

[0036] In some embodiments, the shooting assistance device 100 includes a clamping mechanism 10 and a support frame 20, with the clamping mechanism 10 connected to the support frame 20. The clamping mechanism 10 is used to clamp a shooting device (not shown), and the support frame 20 is used to support the shooting device. The shooting device can be an electronic device such as a mobile phone, tablet, or camera. Clamping the shooting device with the clamping mechanism 10 helps to obtain a stable shooting effect and improve the shooting quality of the shooting device.

[0037] Please refer to the following: Figures 3 to 5In some embodiments, the clamping mechanism 10 includes a connector 11, a clamping member 12, and a locking assembly 13. The connector 11 is connected to the support frame 20. The clamping member 12 has a first surface 121 and a second surface 122 disposed opposite to each other. The first surface 121 is configured to abut against a target object (specifically, a shooting device) to support the shooting device. Understandably, when the clamping member 12 clamps the shooting device, the shooting device abuts against the first surface 121.

[0038] In some embodiments, the clamping member 12 is provided with a mounting portion 123, which is located on the second surface 122. The mounting portion 123 is rotatably mounted on the connector 11, so that the clamping member 12 can rotate relative to the connector 11. Through the rotatable connection between the mounting portion 123 and the connector 11, the user can adjust the angle of the shooting device according to their own preferences, thereby meeting the usage needs of different users or different scenarios.

[0039] For example, in the initial state, the shooting device is in horizontal shooting mode. When vertical shooting is required, the user only needs to rotate the clamp 12 by 90° to change the shooting device from horizontal to vertical shooting mode.

[0040] Please see Figure 5 In some embodiments, the mounting portion 123 is provided with a plurality of locking slots 124, which are arranged in a ring around the rotation axis of the clamping member 12. For example, there are four locking slots 124, which are equally spaced on the mounting portion 123 and arranged in a ring around the rotation axis of the clamping member 12.

[0041] In other embodiments, the number of lock slots 124 may also be 5, 6, or other numbers. This application does not limit this number, and those skilled in the art can choose according to the actual situation.

[0042] Please refer to the following: Figure 3 , Figure 4 as well as Figure 6 In some embodiments, the locking assembly 13 includes a latch 131 and a pusher 132 cooperating with the latch 131. The latch 131 is provided with a first groove 1311 and a second groove 1312, and the pusher 132 is configured to be movable to the first groove 1311 or the second groove 1312.

[0043] When the pusher 132 is in the first groove 1311, the latch 131 separates from the lock groove 124, and the clamping member 12 can rotate relative to the connector 11. When the pusher 132 is in the second groove 1312, the latch 131 is embedded in either lock groove 124 to prevent the clamping member 12 from rotating relative to the connector 11.

[0044] Understandably, when it is necessary to adjust the shooting angle of the shooting device, the user drives the pusher 132 to move to the first groove 1311, so that the locking tongue 131 separates from the locking groove 124. At this time, the clamping member 12 can rotate relative to the connecting member 11, that is, the clamping member 12 and the connecting member 11 are in the unlocked state.

[0045] When the shooting device located in the clamp 12 rotates to the target shooting angle (specifically, the shooting angle required by the user), the user drives the pusher 132 to move to the second groove 1312, so that the locking tongue 131 is engaged in the corresponding locking groove 124. At this time, the locking tongue 131 prevents the clamp 12 from rotating relative to the connector 11, that is, the clamp 12 and the connector 11 are in a locked state.

[0046] The clamping mechanism 10 provided in this application can unlock and lock the clamping member 12 by engaging the locking tongue 131 with the locking groove 124. Moreover, the "embedded locking" has a strong locking capability, which helps to reduce the risk of the clamping member 12 shaking or vibrating and improve the shooting effect of the shooting device.

[0047] In some embodiments, both the latch 131 and the pusher 132 are slidably mounted on the connector 11. The latch 131 achieves separation from and insertion into the lock groove 124 through sliding, which is not only intuitive and simple to operate, but also simple and reliable in structure.

[0048] Please refer to the following: Figures 6 to 8 In some embodiments, the sliding direction of the latch 131 intersects the sliding direction of the pusher 132. Specifically, the sliding direction of the latch 131 intersects the direction of the rotation axis (the sliding direction intersects the rotation axis at a certain acute or obtuse angle), and the sliding direction of the pusher 132 is parallel to the direction of the rotation axis. By obliquely positioning the latch 131, it is beneficial to avoid components in the connector 11 (such as other parts, wire harnesses, bearing ends, etc.).

[0049] In some embodiments, the sliding direction of the latch 131 may also be parallel to the sliding direction of the pusher 132. Specifically, the sliding direction of the latch 131 is parallel to the direction of the rotation axis, while the sliding direction of the pusher 132 intersects the direction of the rotation axis.

[0050] Please refer to the following: Figure 4 , Figure 6 as well as Figure 9 In some embodiments, the locking tongue 131 includes a tongue portion 1314 and a pressure receiving portion 1313, with the tongue portion 1314 mounted on the pressure receiving portion 1313. The pressure receiving portion 1313 is slidably mounted on the connector 11 in a direction perpendicular to the rotation axis. The pushing member 132 is slidably mounted on the connector 11 in a direction parallel to the rotation axis.

[0051] The pressure-bearing part 1313 is provided with a first groove 1311 and a second groove 1312. The first groove 1311 and the second groove 1312 are distributed at intervals along a direction parallel to the rotation axis. Along a direction perpendicular to the rotation axis, the distance between the bottom of the first groove 1311 and the rotation axis is defined as D1, and the distance between the bottom of the second groove 1312 and the rotation axis is defined as D2, where D1 < D2. In other words, the first groove 1311 is closer to the rotation axis than the second groove 1312.

[0052] Understandably, when the pusher 132 moves from the second groove 1312 to the first groove 1311 in a direction parallel to the axis of rotation, the pusher 132 can drive the pressure portion 1313 away from the axis of rotation in a direction perpendicular to the axis of rotation, so that the tongue 1314 separates from the locking groove 124.

[0053] When the pusher 132 moves from the first groove 1311 to the second groove 1312 in a direction parallel to the rotation axis, the pusher 132 can drive the pressure portion 1313 to approach the rotation axis in a direction perpendicular to the rotation axis, so that the tongue 1314 is embedded in the corresponding locking groove 124.

[0054] It is worth noting that when the pusher 132 moves in a direction parallel to the rotation axis, the connector 11 always constrains the pusher 132 to a position perpendicular to the rotation axis. Furthermore, in a direction perpendicular to the rotation axis, the difference D3 (i.e., D2-D1) between the bottom of the first groove 1311 and the bottom of the second groove 1312 is equal to the length of the portion of the latch 131 embedded in the lock groove 124, which is the displacement distance D3 of the latch 131.

[0055] Please refer to the following: Figure 6 , Figure 9 as well as Figure 10 In some embodiments, the first groove 1311 and the second groove 1312 are located on the same side of the tongue 1314 in a direction parallel to the rotation axis. Alternatively, in some embodiments, the first groove 1311 and the second groove 1312 are located on opposite sides of the tongue 1314 in a direction parallel to the rotation axis.

[0056] In some embodiments, the pressure-receiving portion 1313 is provided with a first mating surface 13131, the two ends of which are respectively connected to the groove wall of the first groove 1311 and the groove wall of the second groove 1312. The pusher 132 is provided with a second mating surface 1321, which is configured to press the first mating surface 13131 when the pusher 132 moves from the second groove 1312 to the first groove 1311, so as to separate the driving bolt 131 from the locking groove 124.

[0057] Please refer to the following: Figure 4 , Figure 6as well as Figure 8 In some embodiments, the locking assembly 13 further includes an elastic element 133, which is mounted between the latch 131 and the connector 11. When the pusher 132 moves from the first groove 1311 to the second groove 1312, the latch 131 is configured to move toward the axis of rotation under the action of the elastic element 133 and engage in either of the locking slots 124.

[0058] By setting the elastic element 133, the locking tongue 131 can be automatically engaged when the pushing element 132 moves from the first groove 1311 to the second groove 1312, making the operation more labor-saving and improving the user experience.

[0059] For example, when it is necessary to unlock the clamping member 12, the pushing member 132 moves from the second groove 1312 to the first groove 1311 in a direction parallel to the rotation axis. The pushing member 132 presses the first mating surface 13131 through the second mating surface 1321, thereby driving the pressed part 1313 away from the rotation axis in a direction perpendicular to the rotation axis, thereby causing the tongue 1314 to separate from the locking groove 124, thus unlocking the clamping member 12. It is worth noting that when the pushing member 132 is located in the first groove 1311, the elastic member 133 is in a compressed state and generates elastic potential energy.

[0060] When it is necessary to lock the clamping member 12, the pushing member 132 moves from the first groove 1311 to the second groove 1312 in a direction parallel to the rotation axis. The pressed part 1313 approaches the rotation axis under the action of the elastic potential energy of the elastic member 133, thereby driving the tongue 1314 to engage in the corresponding locking groove 124, thereby locking the clamping member 12. It is worth noting that when the pushing member 132 is located in the second groove 1312, the elastic member 133 is in its natural state.

[0061] In other embodiments, the locking tongue 131 can be moved directly by the pushing member 132, eliminating the elastic member 133. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0062] Please refer to the following: Figure 7 , Figure 8 as well as Figure 11 In some embodiments, the connector 11 has a receiving cavity 111, and the locking tongue 131 is slidably mounted in the receiving cavity 111. A pusher 132 is mounted on the outer wall of the connector 11 and partially extends into the receiving cavity 111, abutting against the locking tongue 131. By mounting the locking tongue 131 in the receiving cavity 111, the locking tongue 131 can be protected, reducing the risk of damage to the locking tongue 131 and extending its service life.

[0063] In some embodiments, the latch 131 has a protrusion 1315, and the connector 11 has a groove 112 in the receiving cavity 111, with the protrusion 1315 slidably mounted in the groove 112. When the pusher 132 moves along the rotation axis to the first groove 1311 or the second groove 1312, the pusher 132 can drive the latch 131 to slide in a direction perpendicular to the rotation axis, thereby causing the protrusion 1315 to slide in the groove 112 in a direction perpendicular to the rotation axis.

[0064] In other embodiments, the locking tongue 131 may also adopt other suitable sliding structures. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0065] In some embodiments, the connector 11 is further provided with a mounting groove 113, which communicates with the receiving cavity 111. The mounting part 123 is rotatably mounted in the mounting groove 113. When the pusher 132 is in the first groove 1311, the latch 131 retracts into the receiving cavity 111 and separates from the locking groove 124. When the pusher 132 is in the second groove 1312, the latch 131 extends into the mounting groove 113 and is embedded in either locking groove 124.

[0066] By setting the mounting slot 113, the structure of the clamping mechanism 10 can be made more compact, thereby reducing the size of the clamping mechanism 10 in the direction of rotation axis, which helps to miniaturize the shooting auxiliary device 100.

[0067] Please see Figure 9 In some embodiments, the pusher 132 includes an operating part 1322 and an actuating part 1323 connected to the operating part 1322. The operating part 1322 is configured for a user to push or pull. The actuating part 1323 is configured to move to a first recess 1311 or a second recess 1312 under the action of the operating part 1322. By providing the operating part 1322, it is convenient for the user to drive the pusher 132 to move, which helps to improve the user experience.

[0068] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
