[0001] The invention relates to the technical field of mobile phone bracket manufacturing, in particular to a mobile phone bracket with a pan / tilt function. Background Art

[0002] With the development of the self-media industry, shooting short videos with mobile phones has become a popular hobby for more and more people. To ensure the stability of the lens during shooting, mobile phone holders are often used during shooting. A gimbal is a support platform used to fix cameras and other shooting equipment. The gimbal is generally equipped with connectors that adapt to the screw holes on the bottom of the camera. Due to the difference in the way mobile phones are fixed (clamping) and cameras are fixed (connecting with connectors), existing mobile phone holders on the market cannot meet the needs of fixing both phones and cameras.

[0003] The existing patent application with application number CN202123297889.9 and titled "A tripod suitable for mobile phones and SLR cameras" discloses a tripod, including a quick-release plate, a pan head and a tripod. The quick-release plate is provided with a clamping arm for clamping the mobile phone and a SLR connector for fixing the SLR camera. The quick-release plate is detachably connected to the pan head. A connecting block is provided at the end of the pan head away from the quick-release plate. The connecting block is hinged to the top of each tripod. A central axis is provided in the connecting block, and a lifting component for driving the pan head to rise and fall is provided in the central axis. This structure simply integrates two fixing components on the tripod to fix the mobile phone and the camera respectively. It is bulky, and it does not change when stored or carried. Moreover, the two fixing components will interfere with each other during use, which is not convenient to use. Therefore, its structure needs to be further improved. Summary of the Invention

DETAILED DESCRIPTION

[0036] The present invention is further described in detail below with reference to the accompanying drawings:

[0037] As shown in Figures 1 to 15, a mobile phone holder with a pan / tilt function includes a support frame 1, a fixed head 2 is provided on the support frame 1, a boss 21 is provided in the middle of the fixed head 2, a connector 31 for connecting a camera is provided on the boss 21, the connector 31 can be retracted into or extended from the boss 21 and assembled on the fixed head 2, a clamp 4 is provided on both sides of the fixed head 2, the clamp 4 includes a movable seat 41 and a clamping claw 42 hingedly matched with the movable seat 41, a groove 42a of a shape adapted to the boss 21 is provided on the clamping claw 42, when the clamping claw 42 is folded and laid down, the boss 21 is located in the groove 42a, and the back of the clamping claw 42 and the boss 21 constitute a supporting plane.

[0038] A locking piece 32 is provided on the fixed head 2, a locking elastic piece 33 is provided between the locking piece 32 and the fixed head 2, a through hole 32a is provided on the locking piece 32, the connecting piece 31 is positioned in the through hole 32a, a locking groove 31a adapted to the locking piece 32 is provided on the connecting piece 31, and a reset elastic piece 34 is provided between the bottom of the connecting piece 31 and the fixed head 2.

[0039] In this embodiment, the resetting elastic member 34 is a conical spring. The locking elastic member 33 is preferably a spring, and one end of the locking member 32 extends out of the fixing head 2 to facilitate pressing.

[0040] An anti-rotation plane 31b is provided on the side wall of the connecting member 31. In this embodiment, a hexagonal prism segment is provided on the connecting member 31, and the six side surfaces of the hexagonal prism segment can all serve as the anti-rotation plane 31b. The connecting member 31 of the gimbal is generally connected to the camera by a threaded connection. Here, an anti-rotation plane 31b is provided. The anti-rotation plane 31b is abutted against the wall of the through hole 32a to form a limit to prevent the connecting member 31 from rotating during connection. The camera is connected to the connecting member 31 through rotation, which facilitates connection. The maximum outer diameter of the hexagonal prism segment is larger than the diameter of the upper connecting head portion of the connecting member 31 to prevent the connecting member 31 from detaching from the fixed head 2 when it bounces upward.

[0041] One side of the fixed head 2 is provided with a telescopic frame 5, and the telescopic frame 5 is provided with a slide groove 5a, and the fixed head 2 is provided with a limit block 22 adapted to the slide groove 5a; a first connecting rod 61 is provided between the clamping head 4 close to the telescopic frame 5 and the telescopic frame 5, and a first elastic member 61a is provided between the first connecting rod 61 and the telescopic frame 5, and a second connecting rod 62 is provided between the clamping head 4 away from the telescopic frame 5 and the fixed head 2, and a second elastic member 62a is provided between the second connecting rod 62 and the fixed head 2.

[0042] The first elastic member 61a and the second elastic member 62a are preferably springs.

[0043] The outer width of the clamping jaw 42 is greater than its inner width. The fixing head 2 is provided with a receiving groove 2a that mates with the outer side of the clamping jaw 42. This design of the clamping jaw 42 being wider on the outside and narrower on the inside prevents slippage during clamping, improving clamping reliability. When the clamping jaw 42 is laid down, the wider portion of the clamping jaw 42 rests within the receiving groove 2a, thereby forming a flat surface between the clamping jaw 42 and the boss 21.

[0044] The clamping jaws 42 are secured with elastic pads 43, which are laterally provided with ridges 43a. The elastic pads 43 can be made of materials such as rubber and silicone. During clamping, the elasticity of the elastic pads 43 provides some protection for the phone, while the ridges 43a increase friction, improving grip reliability and stability.

[0045] An accessory slot 42b is provided on the clamping jaw 42. The accessory slot 42b can be used to connect accessories such as a lamp and a microphone (the accessory is provided with a connecting portion that is compatible with the accessory slot 42b).

[0046] The mobile phone holder of the present invention can be used to hold a mobile phone or transformed into a pan / tilt head for connecting a camera. As shown in Figures 1 and 2, when holding a mobile phone, the connector 31 is pressed downward to retract into the fixed head 2. When the connector 31 descends, the locking member 32, under the action of the locking elastic member 33, engages the locking groove 31a of the connector 31 to prevent the connector 31 from ejecting upward. The chuck 4 is pulled out to both sides. On the side with the telescopic frame 5, the chuck 4 and the telescopic frame 5 are initially extended outward together until the limit block 22 abuts against the end surface of the slide groove 5a on the telescopic frame 5, reaching the extension limit of the telescopic frame 5. Continuing to pull outward, the first connecting rod 61 overcomes the elastic force of the first elastic member 61a and extends outward. On the side without the telescopic frame 5, when the chuck 4 is pulled out, the second connecting rod 62 overcomes the elastic force of the second elastic member 62a and extends outward. When clamping a mobile phone, the first elastic member 61a and the second elastic member 62a provide a force to retract the clamping head 4 inward, so that the clamping heads 4 on both sides have a tendency to retract inward, thereby clamping the mobile phone. Since the connecting member 31 is retracted into the fixing head 2, it will not affect the clamping of the mobile phone.

[0047] The mobile phone clamping structure utilizes a telescopic frame 5 to form a two-stage structure. When clamping a mobile phone, the clamping heads 4 are pulled out to the sides, and the telescopic frame 5 can increase the distance between the two clamping heads 4, thereby meeting the needs of clamping the mobile phone. When the clamping heads 4 are retracted, the telescopic frame 5 retracts into the fixed head 2, taking up no space, and can reduce the volume occupied when stored. Under the premise of being able to achieve the purpose of clamping the mobile phone, the volume is smaller when folded, effectively reducing the space occupied when stored. Furthermore, when storing, the clamping jaws 42 are tilted inward to further reduce the storage volume.

[0048] As shown in Figures 3 and 4, when used as a pan / tilt to fix a camera, the locking member 32 is pressed inward, causing the locking member 32 to disengage from the locking groove 31a of the connecting member 31. The connecting member 31 will then spring upward under the action of the reset elastic member 34 and extend out of the boss 21 of the fixed head 2. At the same time, the telescopic frame 5 retracts into the fixed head 2, the clamping heads 4 on both sides retract, and the clamping claws 42 are tilted inward. The boss 21 is located in the groove 42a, so that the back of the clamping claws 42 on both sides and the boss 21 can form a flat surface for supporting the camera (due to the small area of ​​the boss 21, the support area can be increased by splicing the back of the clamping claws 42, improving the stability of the support). In addition, tilting the clamping claws 42 on both sides can also prevent the upright clamping claws 42 from affecting the fixation of the camera. The camera is fixed to the fixed head 2 via the connecting member 31.

[0049] A ball head seat 7 is provided between the support frame 1 and the fixed head 2, the center of the support frame 1 is equipped with a center rod 8, the upper end of the center rod 8 is provided with a ball head 81, the fixed head 2 is provided with a ball head seat 7 that cooperates with the ball head 81, the ball head seat 7 is provided with a spherical cavity 7a, and the ball head seat 7 is also radially provided with an adjustment groove 7b that communicates with the spherical cavity 7a; an angle locking piece 71 is provided on the ball head seat 7, and an angle locking block 72 is provided between the angle locking piece 71 and the ball head 81. When the angle is locked, the angle locking piece 71 acts on the angle locking block 72 to press it tightly against the surface of the ball head 81 to achieve locking.

[0050] As shown in Figure 11, the angle locking piece 71 is hinged to the ball head seat 7, the head of the angle locking piece 71 is provided with a first protrusion 71a, and the ball head seat 7 is provided with a guide groove 7c, and the angle locking block 72 can be slidably placed in the guide groove 7c.

[0051] The ball head seat 7 is provided with a receiving groove that is compatible with the angle locking member 71. When the angle is locked, the angle locking member 71 is placed in the receiving groove, and the tail end of the angle locking member 71 is tilted and extends out of the receiving groove. The provision of the receiving groove allows the angle locking member 71 to be hidden in the receiving groove when the angle is locked, making the structure more compact and smaller. The tail end extending out of the receiving groove facilitates the lifting of the angle locking member 71 for unlocking.

[0052] As shown in Figure 7, the center rod 8 and the support frame 1 can be raised and lowered. A lifting locking piece 91 is provided on the support frame 1. A lifting locking block 92 is provided between the lifting locking piece 91 and the center rod 8. The lifting locking piece 91 is hinged to the support frame 1. The head of the lifting locking piece 91 is provided with a second protrusion 91a. The lifting locking block 92 is slidably matched with the support frame 1; when lifting and locking, the lifting locking piece 91 acts on the lifting locking block 92 to press it tightly against the surface of the center rod 8 to achieve locking.

[0053] In this embodiment, the support frame 1 includes three support legs. When the three support legs are folded, they form a columnar structure. There is a gap between the support legs. When lifting and locking, the lifting locking member 91 is placed in the gap between the support legs, and the lifting locking member 91 is tilted up, which makes it convenient to pull up the lifting locking member 91 for unlocking operation.

[0054] As shown in Figure 15, the fixed head 2 is rotatably connected to the ball head seat 7, the ball head seat 7 is provided with an assembly column 73, the outer periphery of the assembly column 73 is evenly provided with positioning grooves 73a, and the fixed head 2 is provided with a positioning portion 2b adapted to the positioning groove 73a.

[0055] Directions:

[0056] When the lifting locking piece 91 is released (pull the lifting locking piece 91 upward), the center rod 8 together with the ball head seat 7 and the fixed head 2 can perform lifting and lowering movements on the support frame 1. After the height adjustment is completed, the lifting locking piece 91 is locked (pull the lifting locking piece 91 downward), so that the second protrusion 91a on the lifting locking piece 91 presses the lifting locking block 92, pushing the lifting locking block 92 inward, so that the inner surface of the lifting locking block 92 presses the surface of the center rod 8, thereby forming a lifting lock.

[0057] When the angle locking piece 71 is released (the angle locking piece 71 is pulled outward), the ball head seat 7 can move on the ball head 81, that is, the ball head seat 7 can be rotated in the horizontal direction, and the adjustment slot 7b can be used to achieve longitudinal rotation. It is worth noting here that when the center rod 8 is at the lower limit position, the longitudinal rotation of the ball head seat 7 will be restricted, and the ball head seat 7 needs to be raised a certain distance before the longitudinal rotation can be completed; after the angle adjustment is completed, the angle locking piece 71 is locked (the angle locking piece 71 is buckled outward), so that the first protrusion 71a on the angle locking piece 71 pushes the angle locking block 72 to move inward, and the angle locking block 72 presses the ball head 81 to complete the locking.

[0058] The mobile phone holder of the present invention can be used to secure a camera (serving as a gimbal) and to hold a mobile phone. The ball mount 7 cooperates with the ball head 81 to achieve both horizontal and vertical angle adjustment, facilitating adjustment of shooting angles. The fixed head 2 is rotatably connected to the ball mount 7, allowing for easy positioning of the mobile phone in either a vertical or horizontal position. The positioning portion 2b on the fixed head 2 cooperates with the positioning groove 73a on the ball mount 7 to ensure reliable support. The angle can be adjusted with minimal effort.

[0059] The above are only preferred embodiments of the present invention and do not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
