The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It is also to be understood that the terminology used in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of the present application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be further understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

The inventor of the application finds that the user uses a motion camera to shoot images, video or audio and record the motion process outdoors or in sports. In a certain sports scenario, the sports camera needs to be fastened to the base of a car, bicycle, surfboard, etc. due to the relatively severe shake that is usually accompanied in sports. And because uncontrollable factors in a motion scene are more, the motion camera is easily impacted by collision and the like. In order to buffer or absorb the impact force applied to the motion camera during the use process, the motion camera is usually mounted on a camera frame, and the camera frame is fastened to a base of an automobile, a bicycle, a surfboard, and the like, so as to effectively protect the camera.

When a motion camera is used for video recording or audio recording, an audio adapter is usually used to transmit an audio signal collected by an external microphone to the motion camera. The audio adapter is provided with an electric connecting wire, an audio jack and a power jack. The microphone may be electrically connected to the audio adapter through the audio jack, thereby enabling the microphone to input audio signals to the motion camera. An external power source may be electrically connected to the audio adapter through the power jack to charge the motion camera.

One of the connection and fixation methods of the existing audio adapter is as follows: the audio adapter is fixed by fixing the audio adapter to the additional assembly and fixing the additional assembly to the camera frame. The connection fixing mode needs to add an additional assembly part, so that the operation is complex, and the use experience of a user is influenced.

The second connection fixing mode of the existing audio adapter is as follows: and a USB plug of an electric connecting wire of the audio adapter is plugged and installed on a USB jack of the motion camera, so that the electric connection and the mechanical connection of the electric connecting wire and the motion camera are realized. However, in this connection fixing manner, the mechanical connection strength of the audio adapter completely depends on the connection strength of the USB plug and the USB jack, and the mechanical connection of the audio adapter and the motion camera is insufficient, so that the connection of the audio adapter is not reliable. In addition, the connection fixing mode completely depends on the connection strength of the USB plug and the USB jack, the weight of the audio adapter is completely applied to the USB plug or the USB jack, the abrasion of the USB plug or the USB jack is easy to accelerate, and after the audio adapter is used for multiple times, along with the abrasion of the USB plug or the USB jack, the reliable mechanical connection of the audio adapter cannot be guaranteed, and the audio adapter is easy to loosen.

To this discovery, the inventor of this application has improved audio frequency adapter and shooting subassembly to compromise audio frequency adapter's connection reliability and connection easy operation, promote user's use and experience. Specifically, a first aspect of the present application provides an audio adapter including: an adapter body; the first connecting piece is convexly arranged on the adapter body; the first connecting piece comprises a first connecting part and a second connecting part, and two ends of the second connecting part are respectively connected to the adapter body and the first connecting part; the size of the first connecting portion along the first direction is larger than that of the second connecting portion along the first direction, and the first connecting portion and the second connecting portion are matched to form a first clamping structure for clamping and fixing the audio adapter to an external unit.

According to a third aspect of the present application, there is provided a camera assembly comprising: a camera frame;

the camera is arranged on the camera frame; and the audio adapter of any one of the first aspect of the present application, wherein the first engaging structure is engaged with the camera frame to fix the audio adapter to the camera frame.

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1, an embodiment of the present application provides an audio adapter 10, where the audio adapter 10 may be used in an electronic device, for inputting an audio signal to the electronic device or charging the electronic device. Illustratively, when the electronic device needs to be charged, an external power source is electrically connected to the audio adapter 10, and the audio adapter 10 is electrically connected to the electronic device, thereby charging the electronic device. When an audio signal needs to be input to the electronic device, the audio input device is electrically connected to the audio adapter 10, and the audio adapter 10 is electrically connected to the electronic device, so that the audio input device can input the audio signal to the electronic device through the audio adapter 10. In this way, the audio adapter 10 can be electrically connected to at least one of the audio input device and the external power source according to actual requirements, so as to input an audio signal to the electronic device and/or charge the electronic device.

In one embodiment, the first direction is a vertical direction when the audio adapter 10 is in use. In one embodiment, the first direction is a horizontal direction when the audio adapter 10 is in use.

In the audio adapter 10 of the above embodiment, the first connecting portion 210 and the second connecting portion 220 have different sizes along the first direction to form the first engaging structure 230, and the audio adapter 10 can be engaged and fixed on the external unit 20 by the first engaging structure 230, so that the audio adapter 10 is reliably connected, the connection operation of the audio adapter 10 is simple, that is, the assembly is simple, and the user experience is improved.

In addition, the audio adapter is fixed by a nut and/or screw structure, which may significantly increase the overall size of the audio adapter 10 and may affect the overall aesthetic appearance of the electronic device and/or the external unit 20. Compared with the audio adapter fixed by adopting a nut and/or screw structure, after the audio adapter 10 is fixed with the external unit 20, the overall size of the audio adapter 10 is small, and the overall aesthetic appearance of the electronic device and/or the external unit 20 is not affected.

The external unit 20 may be a camera frame, a pan-tilt head, or other mounting structure capable of mounting a camera. The following explanation will be given taking the external unit 20 as a camera frame as an example.

The first mating slot 201 and the second mating slot 202 mate to form a first mating structure 21.

When the audio adapter 10 needs to be fixed, the first connecting portion 210 of the first connecting member 200 is engaged with the second engaging slot 202 of the external unit 20, and the first engaging structure 230 is engaged with the first engaging structure 21, so that the audio adapter 10 can be reliably fixed on the external unit 20.

In some embodiments, the first direction is the direction of the X axis in fig. 1 and 3, for example, the positive direction of the X axis. The width of the notch of the groove body refers to the width of the notch of the groove on the groove body along the first direction.

It is understood that, when the audio adapter 10 and the external unit 20 are disassembled, the first connector 200 of the audio adapter 10 is slid into or out of the first mating structure 21 of the external unit 20 in the Z direction of fig. 3, thereby snapping and fixing the audio adapter 10 to the external unit 20 or separating the audio adapter 10 from the external unit 20.

The shape of the first engaging structure 230 can be designed into any shape according to actual requirements, such as T-shape, L-shape, etc., as long as it can be engaged with the first engaging structure 21 to engage and fix the audio adapter 10 on the external unit 20. It is understood that the T-shape herein generally means that the projection shape of the first engaging structure 230 on the XOY plane in fig. 1 and 3 is T-shaped or substantially T-shaped, for example, the included angle between the first connecting portion 210 and the second connecting portion 220 is 80 °, 85 °, 90 °, or any other suitable angle between 80 ° and 90 °. Illustratively, the first connecting portion 210 and the second connecting portion 220 cooperate to form a T-shaped first engaging structure 230.

The first bent portion 2011 is at least partially inserted into the first card slot 300. The first connecting portion 210 is clamped in the groove of the second mating groove 202. In this way, after the first engaging structure 230 is engaged with the first engaging structure 21, the first bent portion 2011 and the groove bottom of the second engaging groove 202 can limit the first engaging structure 230 from the positive direction and the negative direction of the Y direction in fig. 1 and 3, thereby providing a guarantee for the audio adapter 10 to be reliably fixed to the external unit 20. In one embodiment, when the audio adapter 10 is in the use state, the first bent portion 2011 and the second engagement groove 202 can limit the first engagement structure 230 from the positive direction and the negative direction of the X direction and the Y direction.

The number of the first card slots 300 may be designed according to actual requirements, such as one, two or more. The number of the first card slots 300 is two, and the two first card slots 300 are oppositely arranged.

The first bent portion 2011 is at least partially inserted into one of the first card slots 300, and the second bent portion 2012 is at least partially inserted into the other first card slot 300. The second connecting portion 220 is inserted into the first fitting groove 2013. The first connecting portion 210 is clamped in the groove of the second mating groove 202. In this way, after the first engaging structure 230 is engaged with the first engaging structure 21, the first card slot 300 can limit the first bent portion 2011 and/or the second bent portion 2012 from the positive direction and the negative direction of the Y direction in fig. 1 and fig. 3, so as to provide a guarantee for the audio adapter 10 to be reliably fixed to the external unit 20.

Referring to fig. 3 to 5, in some embodiments, the first connecting portion 210 is provided with a protrusion 211. The protrusion 211 extends away from the first connection portion 210 in the first direction for interference-fitting the audio adapter 10 with the external unit 20, and particularly, the protrusion 211 is interference-fitted with the inner wall of the second fitting groove 202 of the external unit. In some embodiments, the second mating groove 202 of the first mating structure 21 is provided with a concave portion (not shown) for mating with the protruding portion 211.

After the first engaging structure 230 is engaged and fixed with the first engaging structure 21 of the external unit 20, the first engaging slot 201 and/or the second engaging slot 202 can limit the first connecting portion 210 to move along the X direction and the Y direction in fig. 1 and 3 or move in the XOY plane.

It will be appreciated that any suitable plastic material may be used for the coupling 150, such as Thermoplastic Polyurethanes (TPU).

For another example, referring to fig. 11, the circuit board 130 is fixed in the accommodating cavity 120 by the positioning posts 113 and the positioning holes 131. In some embodiments, the housing 110 is provided with positioning posts 113, and the circuit board 130 is provided with positioning holes 131. The positioning posts 113 of the housing 110 are inserted into the positioning holes 131 of the circuit board 130, so as to fix the circuit board 130 in the accommodating cavity 120. Compared with the fixing manner by the injection molding coupler 150, the audio adapter 10 has no risk of molten plastic pouring at the first electrical connection port 141, has low processing risk, and is easy to process.

Exemplarily, the positioning column 113 is disposed on the first housing 111. The positioning column 113 and the first connecting member 200 are respectively disposed on two opposite sides of the first housing 111.

Referring to fig. 1 to 11, in some embodiments, the adaptor body 100 further includes a slip prevention member 160 for increasing a frictional force between the first connector 200 and the external unit 20. At least a portion of the anti-slip member 160 protrudes from a side of the first connecting portion 210 facing away from the second connecting portion 220. When the first connector 200 of the audio adapter 10 is engaged with and fixed to the first engaging structure 21 of the external unit 20, the anti-slip member 160 can abut against the second engaging slot 202 of the external unit 20 and form a friction force with the second engaging slot 202. Thus, under the action of friction force, the audio adapter 10 cannot easily slide out of the first matching groove 201 and the second matching groove 202, and the connection reliability of the audio adapter 10 is improved.

In some embodiments, the anti-slip member 160 can be connected to the first connector 200 by any suitable connection method, as long as the anti-slip member 160 can increase the friction between the first connector 200 and the external unit 20 when the first connector 200 is fixed with the first mating structure 21. For example, the anti-slip member 160 and the first connecting member 200 can be connected by at least one of a snap connection, an adhesive connection, and the like.

It can be understood that, since the audio adapter 10 has the anti-slip member 160 and the first connecting member 200, when the audio adapter 10 is fixedly engaged with the external unit 20, the friction between the first connecting member 200 and the external unit 20 can be increased without installing an additional anti-slip structure, thereby facilitating the operation of the user and improving the user experience. The audio adapter 10 of the present embodiment has a compact structure, the audio adapter 10 can be reliably fixed to the external unit 20, and the user can operate the audio adapter conveniently and simply.

Referring to fig. 3 to 5, in some embodiments, a concave groove 212 is formed on a side of the first connecting portion 210 facing away from the second connecting portion 220.

Specifically, the cleat 160 is partially located within the second connecting portion 220, and a portion of the cleat 160 can protrude from the bottom of the recessed channel 212. The recessed groove 212 can enable the surface of the anti-slip member 160 away from the circuit board 130 to abut against the bottom wall of the second matching groove 202 of the first matching structure 21, and prevent the first connecting member 200 from being too thick to cause the defect of shrinkage during molding, and can save the material of the first connecting portion 210 and reduce the cost.

Referring to fig. 8 and 9, in some embodiments, the first connecting member 200 is provided with a mounting groove 240 communicating with the recessed groove 212, and a portion of the anti-slip member 160 is located in the mounting groove 240. Part of the anti-slip member 160 is located in the fitting groove 240 and the other part protrudes from the bottom of the recess groove 212.

Referring to fig. 8 and 9 in conjunction with fig. 1 and 3, in some embodiments, the mounting slot 240 extends through the first connector 200. Illustratively, the fitting groove 240 penetrates the first connector 200 in the Y direction of fig. 1 and 3, so that both the recessed groove 212 and the receiving cavity 120 communicate with the fitting groove 240, facilitating the installation and fixation of the anti-skid member 160.

Referring to fig. 9 and 10, in some embodiments, the anti-slip member 160 includes a first connector 161. A portion of the first connection body 161 is positioned in the fitting groove 240, and another portion of the first connection body 161 protrudes from the bottom of the recess groove 212. When the first engaging structure 230 is engaged and fixed with the first engaging structure 21, one side of the first connecting body 161 away from the assembling groove 240 can abut against the second engaging groove 202 of the first engaging structure 21, so as to increase the friction between the first engaging structure 230 and the first engaging structure 21.

In some embodiments, after the first engaging structure 230 is engaged and fixed with the first engaging structure 21 of the external unit 20, the first engaging slot 201 and/or the second engaging slot 202 can limit the first connecting portion 210 to move in the X direction or the Y direction in fig. 3, or limit the first connecting portion 210 to move in the XOY plane. The side of the first connector 161 away from the fitting groove 240 can abut against the second fitting groove 202 of the first fitting structure 21, and the first connector 210 can be restricted from moving in the Z direction in fig. 3 or moving in the YOZ plane, so that the audio adapter 10 can be further reliably fixed to the external unit 20 in a snap-fit manner, and the connection reliability of the audio adapter 10 can be improved.

In some embodiments, the anti-slip member 160 and the protrusion 211 may be provided at the same time, and the combined action of the anti-slip member 160 and the protrusion 211 prevents the first connector 200 from moving along the length direction of the adaptor body 100 (i.e., the Z direction in fig. 3), thereby further ensuring the connection reliability of the audio adaptor 10.

The size of the second connection body 162 is larger than that of the first connection body 161 so that the first connection body 161 and the second connection body 162 cooperate to form a step. Illustratively, the fitting groove 240 has a step that cooperates with the step, and the step can restrict the movement of the anti-slip member 160 in the positive direction of the Y direction in fig. 1 and 3. That is, the engagement of the step and the step can limit the movement of the anti-slip member 160 toward the second connecting portion 220.

In some embodiments, the step and the circuit board 130 can limit the movement of the anti-slip member 160 in the positive direction and the negative direction of the Y direction in fig. 1 and 3, respectively, so as to fix the anti-slip member 160. That is, the engagement of the step and the step of the fitting groove can restrict the movement of the anti-slip member 160 toward the second connecting portion 220, and the circuit board 130 can restrict the movement of the anti-slip member 160 toward the second connecting member 400. In other embodiments, the step and the engaging member 150 can limit the movement of the anti-slip member 160 in the positive and negative directions of the Y direction in fig. 1 and 3, respectively, thereby achieving the fixation of the anti-slip member 160.

In some embodiments, the cleats 160 are resilient structures. In some embodiments, the material of the anti-slip member 160 includes at least one of silicone, rubber, and the like, which have elasticity. Because the elastic anti-slip member 160 has a certain elasticity, when the audio adapter 10 is fastened and fixed with the external unit 20, the anti-slip member 160 can be elastically deformed, so that the first fastening structure 230 and the first mating structure 21 are reliably connected, and the bottom wall of the second mating groove 202 of the first mating structure 21 is not abraded, thereby protecting the external unit 20.

In other embodiments, the anti-slip member 160 may have any other suitable structure, such as anti-slip patterns or anti-slip bumps.

In some embodiments, the mounting slot 240 communicates with the receiving cavity 120. Illustratively, the second connector 162 has a size greater than that of the fitting groove 240.
