Description

Technical Field

[0001] This application relates to the technical field of gimbal clamping mechanisms, and more particularly to a clamping mechanism and a handheld gimbal. Background Technology

[0002] With the rise of the live streaming industry, more and more people are shooting or live streaming with their mobile phones. When shooting with a handheld phone, hand tremors can cause the footage to shake, reducing the quality of the shot. To address this, gimbals have emerged. A gimbal is a carrier for a mobile phone, similar to a selfie stick. It works by clamping the phone. When the gimbal is working, it produces a movement that is opposite to the movement of the hand, thus ensuring that the phone is relatively stable when shooting, resulting in stable and shaky footage.

[0003] In order to save the trouble of manually adjusting the phone angle to capture the face during photography or videography, an external auxiliary device is usually added to the clamping part and electrically connected to the control console of the gimbal itself to achieve the function of automatically tracking the face. In the existing technology, when the clamping part holds the phone, the clamping part needs to be stretched outward. At this time, the wiring of the external auxiliary device will be exposed, which affects the overall aesthetics. Moreover, when the clamping part retracts inward, it is easy to trap the exposed wiring, reducing the lifespan of the external auxiliary device wiring and affecting the user experience. Utility Model Content

[0004] This application provides a clamping mechanism and a handheld gimbal to solve the problems of exposed wiring of external auxiliary equipment, which affects the overall aesthetics and makes the wiring easy to break, thus reducing the service life of the external auxiliary equipment.

[0005] In a first aspect, this application provides a clamping mechanism, comprising: The connecting part has a first cavity; A first clamping arm (2) connected to one side of the connecting part (1) and a second clamping arm (3) movably connected to the other side of the connecting part (1) are used to clamp an external shooting device; The second clamping arm is provided with a second cavity; and the second clamping arm is also provided with a metal contact, which is used to electrically connect with external auxiliary equipment; A wire passage is provided in the second clamping arm; the wire passage has an inlet and an outlet, the inlet is connected to the first cavity, and the outlet is connected to the second cavity; and the metal contacts are electrically connected to the wire passing through the outlet. When the second clamping arm moves relative to the connecting part, the wire passage moves synchronously with the second clamping arm, and the wire inlet of the wire passage is always connected to the first cavity.

[0006] Furthermore, a first PCBA board is provided inside the second cavity. The input end of the first PCBA board is electrically connected to the wire passing through the outlet, and the output end of the first PCBA board is electrically connected to the metal contact.

[0007] Furthermore, the second clamping arm is provided with a third cavity communicating with the second cavity; the end of the wire passage with the wire outlet abuts against the outer wall of the third cavity; so that the wire passes through the wire passage and extends from the third cavity into the second cavity and then connects electrically with the metal contact.

[0008] Furthermore, the first cavity is provided with a first wire passage hole and a second wire passage hole. The wire passage channel passes through the second wire passage hole and communicates with the first cavity. The first wire passage hole is used to connect the first cavity and the external handheld platform.

[0009] Furthermore, the cable passage includes: The first long groove has one end located on the second clamping arm and the other end of the first long groove extends through the second wire hole into the first cavity. The second long groove is combined with the first sliding groove, so that the two ends of the first long groove and the second long groove respectively form an inlet and an outlet.

[0010] Furthermore, the first wire hole is provided with a connecting shaft for connecting to a handheld gimbal. The connecting shaft is a hollow structure used to connect the first cavity and the external handheld gimbal.

[0011] Furthermore, it also includes: a rotation control assembly, the rotation control assembly comprising: The second PCBA board is disposed in the first cavity and connected to the external handheld gimbal unit through the first wire hole; A motor is used to control the rotation of the connecting shaft and is electrically connected to the second PCBA board.

[0012] Furthermore, one end of the conductor of the second PCBA board is electrically connected to the metal contact after passing through the second cavity and the wire passage in sequence.

[0013] Furthermore, the connecting part is provided with a fourth cavity on one side corresponding to the second clamping arm. The fourth cavity is provided with a spring-loaded assembly, which includes a spring and a connecting rod. One end of the spring is connected to the bottom wall of the fourth cavity, and the other end is connected to one end of the connecting rod. The end of the connecting rod away from the spring is connected to the second clamping arm, so that the second clamping arm can reciprocate relative to the connecting part.

[0014] Secondly, this application provides a handheld gimbal, including: a clamping structure as described above.

[0015] The technical solution provided in this application has the following advantages compared with the prior art: The technical solution of this application provides a wire passage on the second clamping arm, with an inlet and an outlet on the wire passage. This allows the wires of the clamping mechanism to extend into the second cavity on the second clamping arm through the inlet and outlet. By setting metal contacts on the second clamping arm, the metal contacts can conduct electricity through the wires located in the second cavity. When an external auxiliary device is connected to the metal contacts, the external auxiliary device can be used normally. At the same time, when the second clamping arm is in the moving state, the wire passage moves synchronously with the second clamping arm. Because of the wire passage, the wires of the clamping mechanism are always within the wire passage, solving the technical problems of exposed wiring and easy damage of wiring in the prior art, and improving the user experience.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. 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.

[0022] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0023] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0024] To address the technical problems of exposed wiring and easy damage in existing technologies, this application provides a clamping mechanism that improves overall aesthetics and enhances user experience.

[0025] Firstly, Figures 1 to 7 A clamping mechanism provided in this application embodiment includes a connecting part 1 having a first cavity 10; a first clamping arm 2 connected to one side of the connecting part 1 and a second clamping arm 3 movably connected to the other side of the connecting part 1, the first clamping arm 2 and the second clamping arm 3 being used to clamp an external shooting device; the second clamping arm 3 having a second cavity 30; and the second clamping arm 3 also having a metal contact 31 for electrical communication with an external auxiliary device; a wire passage 4 disposed in the second clamping arm 3; and the wire passage 4 having an inlet 40 and an outlet 41, the inlet 40 communicating with the first cavity 10, and the outlet 41 communicating with the second cavity 30; and the metal contact 31 being electrically connected to a wire passing through the outlet 41; when the second clamping arm 3 moves relative to the connecting part 1, the wire passage 4 moves synchronously with the second clamping arm 3, and the inlet 40 of the wire passage 4 is always communicating with the first cavity 10.

[0026] Understandably, the first clamping arm 2 and the second clamping arm 3 cooperate to form a cavity for placing external shooting equipment, while simultaneously securing the external shooting equipment to the connecting part 1. When the external auxiliary equipment is installed on the second clamping arm 3, the metal contact 31 connects to the external auxiliary equipment, allowing it to be powered on. The entire process of energizing the metal contact 31 involves the wire first entering the wire passage 4 from the inlet 40, then extending from the outlet 41 to the second cavity 30. One end of 31 is located inside the second cavity 30, so when the wire is energized, the metal contact 31 is also energized. Since the wire passage 4 is set on the second clamping arm 3, when the second clamping arm 3 extends outward, the wire passage 4 will move synchronously with the second clamping arm 3. Therefore, the wire in the wire passage 4 can avoid being directly exposed outside the clamping mechanism, solving the problem of the wire being exposed outside affecting the appearance. At the same time, it can also prevent the second clamping arm 3 from clamping the wire when it retracts inward, solving the problem of affecting the life of external auxiliary equipment.

[0027] like Figure 5 As shown, in the technical solution of this embodiment, a first PCBA board 32 is provided in the second cavity 30. The input end of the first PCBA board 32 is electrically connected to the wire passing through the outlet 41, and the output end of the first PCBA board 32 is electrically connected to the metal contact 31.

[0028] Understandably, the first PCBA board 32 is electrically connected to the control console of the handheld gimbal and also to the metal contact 31. Therefore, the control console of the handheld gimbal can directly control whether the metal contact 31 is powered on, and indirectly control whether to turn on or off external auxiliary equipment, thus enhancing the user experience.

[0029] like Figure 5 As shown, in the technical solution of this embodiment, the second clamping arm 3 is provided with a third cavity 33 that communicates with the second cavity 30; the end of the wire passage 4 with the wire outlet 41 abuts against the outer wall of the third cavity 33; after the wire passes through the wire passage 4, it extends from the third cavity 33 into the second cavity 30 and then connects to the metal contact 31 electrically.

[0030] It is understandable that the third cavity 33 is located opposite to the outlet 41. Therefore, the end of the wire passage 4 located at the outlet 41 is in contact with the outer wall of the third cavity 33. The third cavity 33 provides space for the wires connecting the metal contact 31 to bend, preventing the outlet 41 from being blocked by the second clamping arm 3, so that the metal contact 31 can be energized or de-energized normally.

[0031] like Figure 2 , Figure 3 and Figure 5As shown, in the technical solution of this embodiment, the first cavity 10 is provided with a first wire passage hole 11 and a second wire passage hole 12. The wire passage channel 4 passes through the second wire passage hole 12 and communicates with the first cavity 10. The first wire passage hole 11 is used to connect the first cavity 10 and the external handheld platform.

[0032] Understandably, the second wire passage hole 12 is designed to keep the wire passage channel 4 inside the connecting part 1, while also effectively restricting the direction of movement of the wire passage channel 4. The first wire passage hole 11 is designed to prevent the wire connected from the handheld gimbal from being exposed, ensuring that the wire is always inside the clamping mechanism and the handheld gimbal.

[0033] like Figure 5 and Figure 7 As shown, in the technical solution of this embodiment, the wire passage 4 includes: a first long groove 42 and a second long groove 43. One end of the first long groove 42 is disposed on the second clamping arm 3, and the other end of the first long groove 42 extends through the second wire passage hole 12 into the first cavity 10. The second long groove 43 is joined with the first sliding groove, so that the two ends of the first long groove 42 and the second long groove 43 respectively form a wire inlet 40 and a wire outlet 41.

[0034] It is understandable that the opening of the first long slot 42 and the opening of the second long slot 43 are set opposite to each other, so the space between the first long slot 42 and the second long slot 43 can be used for the wire to pass through, preventing the wire from being exposed.

[0035] like Figures 2 to 4 As shown, in the technical solution of this embodiment, the first wire hole 11 is provided with a connecting shaft 110 for connecting with the handheld gimbal. The connecting shaft 110 is a hollow structure for connecting the first cavity 10 and the external handheld gimbal.

[0036] Understandably, the connecting shaft 110 allows the clamping mechanism to rotate as a whole, making it suitable for different shooting scenarios and angles.

[0037] like Figure 3 As shown, the technical solution of this embodiment also includes: a control rotation component 5, which includes: a second PCBA board 50 and a motor 51. The second PCBA board 50 is disposed in the first cavity 10 and connected to the external handheld gimbal unit through the first wire hole 11. The motor is used to control the rotation of the connecting shaft 110 and is electrically connected to the second PCBA board 50.

[0038] Understandably, since a second PCBA board 50 electrically connected to the handheld gimbal is provided, and the motor 51 is also electrically connected to the second PCBA board 50, the rotation angle of the clamping mechanism can be automatically adjusted through the control panel of the handheld gimbal, thus improving the user experience.

[0039] like Figure 3 As shown, in the technical solution of this embodiment, one end of the conductor of the second PCBA board 50 is electrically connected to the metal contact 31 after passing through the second cavity 30 and the wire passage 4 in sequence.

[0040] Understandably, since a second PCBA board 50 is provided, the wires connecting the metal contacts 31 can be directly connected from the second PCB, which facilitates subsequent disassembly and maintenance.

[0041] like Figure 6 As shown, in the technical solution of this embodiment, the connecting part 1 is provided with a fourth cavity 13 on one side corresponding to the second clamping arm 3. The fourth cavity 13 is provided with a spring assembly 6. The spring assembly 6 includes a spring 60 and a connecting rod 61. One end of the spring 60 is connected to the bottom wall of the fourth cavity 13, and the other end is connected to the connecting rod 61. The end of the connecting rod 61 away from the spring 60 is connected to the second clamping arm 3, so that the second clamping arm 3 can reciprocate relative to the connecting part 1.

[0042] Understandably, the spring-loaded component 6 allows the clamping mechanism to adapt to external shooting devices of different sizes, making the position of the external shooting device more stable. When a large external shooting device needs to be clamped, the second clamping arm 3 is first extended outward, and the spring 60 is in a stretched state. The space between the first clamping arm 2 and the second clamping arm 3 becomes larger. Then, the external shooting device is placed between the first clamping arm 2 and the second clamping arm 3. At this time, one side of the external shooting device abuts against the first clamping arm 2, and the second clamping arm 3 on the other side contracts inward due to the stretching force of the spring 60, thus clamping the external shooting device on the clamping mechanism.

[0043] It should be noted that the first clamping arm 2 can be provided with a spring-loaded component 6 having the same structure as the second clamping arm 3. Correspondingly, the connecting part 1 located on one side of the first clamping arm 2 can also be provided with a fourth cavity 13 for installing the spring-loaded component 6. When the first clamping arm 2 is provided with the same spring-loaded component 6, the clamping force of the clamping mechanism can be further enhanced.

[0044] Secondly, such as Figure 8 As shown, this application also provides a handheld gimbal, including the clamping mechanism as described above.
