[0049] Please refer to Figure 1 , the present utility model provides a mobile phone expansion component 2, which includes an expansion member 21 and a locking component 23, and forms a receiving cavity 211a. At least one functional interface 211 for connecting external photographic and video auxiliary accessories is provided on the expansion member 21; the locking component 23 is disposed on the expansion member 21 and is used to lock the mobile phone 1 in the receiving cavity 211a.

[0050] The locking component 23 is used to lock the mobile phone 1 in the receiving cavity 211a to ensure that the mobile phone 1 is firmly fixed in the mobile phone expansion component 2 and prevent accidental detachment, so as to ensure the use safety. The design of the locking component 23 generally includes one or more locking mechanisms, such as a pin shaft and a locking mechanism, which work together to ensure that the mobile phone 1 or other devices are safely fixed in the receiving cavity 211a of the mobile phone expansion component 2. This design not only provides physical protection but also increases the convenience of use, enabling users to conveniently fix the mobile phone 1 or other devices in a specific position while ensuring their safety and usability.

[0051] In this embodiment, by providing the locking component 23, the mobile phone 1 can be firmly fixed, ensuring that the mobile phone 1 will not easily fall off or be taken out of the receiving cavity 211a, and users do not need to perform cumbersome operations. They only need to control the locking component 23 to achieve the locking and unlocking between the mobile phone 1 and the mobile phone expansion component 2, greatly improving the convenience and efficiency of use.

[0052] In some embodiments, the expansion member 21 is provided with at least one functional interface 211, such as a cold shoe port, a quick release port or a 1 / 4 thread interface, which can be used to connect a series of types of photographic and video auxiliary accessories such as a handle, a fill light, a microphone, a filter, a bracket, etc., increasing the functional diversity of the mobile phone expansion component 2 provided in this embodiment of the application and meeting the different needs of different users.

[0053] Please refer to Figure 2 where the expansion member 21 is provided with an installation cavity 210 which communicates with the accommodation cavity 211a; the locking assembly 23 includes a locking member 231 which is movably disposed in the installation cavity 210 and is adapted to enter or exit the accommodation cavity 211a under the action of an external force for locking the mobile phone 1 in the accommodation cavity 211a.

[0054] In this embodiment, the design of the locking member 231 is mainly to achieve the detachable or adjustable property between the mobile phone 1 and the mobile phone expansion assembly 2. Through the action of an external force, such as manual operation or mechanical drive, the locking member 231 can enter or exit a specific accommodation cavity 211a, thereby realizing functions such as fixing, adjusting or disassembling between the mobile phone 1 and the mobile phone expansion assembly 2.

[0055] Exemplarily, please refer to Figure 4 where the locking member 231 can be connected to the expansion member 21 through a directional angle rotating shaft. The directional angle rotating shaft usually has specific rotation angle limitation and locking mechanism to ensure that it can accurately enter or exit the accommodation cavity 211a under the action of an external force. Such a directional angle rotating shaft may include the following key components:

[0056] 1. Rotating shaft body: This is the main body part of the rotating shaft, responsible for transmitting torque and bearing bending moment.

[0057] 2. Bearing: Supports the rotating shaft body, reduces friction and wear, and ensures smooth rotation.

[0058] 3. Limiting mechanism: Limits the rotation angle of the rotating shaft body to prevent it from rotating excessively or deviating from the predetermined position.

[0059] Specifically, the locking mechanism of the locking member 231 is: under the action of an external force, the rotating shaft body is locked at a specific position, and the locking member 231 can stably stay at a predetermined angular position while preventing it from rotating excessively or closing accidentally to ensure its stability.

[0060] Please refer to Figure 5 where in some embodiments, the locking assembly 23 further includes an elastic member 232 which is disposed in the installation cavity 210 and is connected to the locking member 231, and the elastic member 232 is adapted to drive the locking member 231 to extend into the accommodation cavity 211a.

[0061] In this embodiment, the elastic member 232 in the locking assembly 23 is disposed in the installation cavity 210 and is connected to the locking member 231. The main purpose of this design is to utilize the elastic force of the elastic member 232 to drive the locking member 231 to move to achieve the locking or unlocking function.

[0062] Specifically, when the elastic member 232 is in a natural state, it will keep the locking member 231 in the accommodating cavity 211a by its elastic force, usually in a locked state, thereby preventing the mobile phone 1 from being easily separated from the accommodating cavity 211a. When unlocking is required, the elastic force of the elastic member 232 is overcome by external operation, so that the locking member 231 moves and exits the accommodating cavity 211a, and the mobile phone 1 can be taken out of the accommodating cavity 211a.

[0063] In this embodiment, the elastic member 232 and the locking member 231 cooperate closely to achieve rapid assembly and disassembly and stable fixation of the components.

[0064] Exemplarily, the elastic member 232 may be a compression spring, or a component with specific elastic potential energy such as a spring, which is not limited in the embodiment of the present application.

[0065] Please refer to Figure 6 In some embodiments, the locking assembly 23 also includes an unlocking member 234, which is movably disposed on the extension member 21. The unlocking member 234 is used to cooperate with the locking member 231 to put the locking member 231 in a locked state extending into the accommodating cavity 211a or in an unlocked state exiting the accommodating cavity 211a.

[0066] When the unlocking member 234 is movably arranged on the extension member 21, it can cooperate with the locking member 231 by moving or rotating, allowing the locking member 231 to extend into the accommodating cavity 211a to achieve a locked state, and allowing the locking member 231 to withdraw from the accommodating cavity 211a to achieve an unlocked state.

[0067] Please continue to refer to Figure 6 In some embodiments, the locking assembly 23 further includes an elastic member 232, which is disposed in the installation cavity 210 and connected to the locking member 231. The elastic member 232 is used to drive the locking member 231 to withdraw from the accommodating cavity 211a when the locking member 231 is in an unlocked state.

[0068] The combined design of the elastic member 232 and the locking member 231 realizes a fast and reliable connection and separation mechanism. Specifically, when the locking member 231 is in the unlocked state, the elastic member 232 is compressed or stretched, thereby generating a restoring force. This restoring force plays a driving role when the locking member 231 exits the accommodating cavity 211a, ensuring that the locking member 231 can be quickly and smoothly moved to the unlocked position, thereby allowing the mobile phone 1 and the mobile phone expansion component 2 to be quickly disassembled or installed.

[0069] This design improves the convenience of operation. By cleverly utilizing the restoring force of the elastic member 232, this structure can achieve rapid switching between locking and unlocking without complex mechanical operations, thereby reducing operation time.

[0070] Please refer to Figure 2 and Figure 3 In some embodiments, the locking member 231 is provided with a locking hole 23a; the unlocking member 234 includes a clamping portion 23c and an unlocking portion 23b. The clamping portion 23c is arranged in the installation cavity 210 for inserting into the locking hole 23a, and the unlocking portion 23b is connected to the clamping portion 23c and at least partially exposed outside the expansion member 21 for toggling the clamping portion 23c to enter or exit the locking hole 23a.

[0071] In this embodiment, by providing the locking hole 23a in the locking member 231, the clamping portion 23c can enter or exit the locking hole 23a, realizing the clamping and separation of the unlocking member 234 and the locking member 231. The working principle of the whole structure depends on the toggling of the unlocking portion 23b. Under the action of the unlocking portion 23b, the clamping portion 23c can enter or exit the locking hole 23a, realizing the clamping and separation of the unlocking member 234 and the locking member 231.

[0072] Since the unlocking portion 23b is exposed outside the expansion member 21, the user can simply toggle the unlocking portion 23b to control the entry and exit of the clamping portion 23c, realizing the quick clamping and separation of the unlocking member 234 and the locking member 231, and further realizing the quick locking and unlocking of the locking member 231 for the mobile phone 1. This design not only ensures the stability of installation but also improves the convenience of operation.

[0073] Please continue to refer to Figure 2 and Figure 3 In some embodiments, the locking assembly 23 further includes a reset member 233. The reset member 233 is arranged in the installation cavity 210 and connected to the unlocking member 234. The reset member 233 is used to drive the clamping portion 23c into the locking hole 23a when the external force on the unlocking portion 23b is withdrawn.

[0074] When an external force is applied to the unlocking portion 23b, the reset member 233 can withstand and transmit this external force through its specific structure and material properties, while maintaining the proper position of the clamping portion 23c and the locking hole 23a. Once the external force on the unlocking portion 23b is withdrawn, the reset member 233 can quickly return to its original state, thereby driving the clamping portion 23c into the locking hole 23a to ensure the stability and reliability of the connection.

[0075] Exemplarily, the reset member 233 can be a compression spring or other components with specific elastic potential energy such as a spring sheet. The embodiments of the present application do not make limitations here.

[0076] Please refer to Figure 7, in some embodiments, the locking member 231 is provided with a first connection structure, and the expansion member 21 is provided with a second connection structure. The first connection structure and the second connection structure are engaged with each other to connect the locking member 231 and the expansion member 21, and to enable the locking member 231 to enter the accommodation cavity 211a;

[0077] Wherein, one of the first connection structure and the second connection structure is a positioning pit, and the other is a positioning protrusion 235 that is engaged with the positioning pit.

[0078] In the above embodiment, when the positioning pit and the positioning protrusion 235 are engaged with each other, the stable connection and accurate positioning of the locking member 231 and the expansion member 21 are realized, so that the locking member 231 enters the accommodation cavity 211a, and then the mobile phone 1 is locked in the accommodation cavity 211a.

[0079] Specifically, the cooperation between the positioning pit and the positioning protrusion 235 is based on the mechanical engagement principle, that is, a mechanical lock is formed between the locking member 231 and the expansion member 21 through the engagement of the concave-convex structure, so as to prevent the two from loosening or sliding during use. When the user needs to take out the mobile phone 1, only a certain external force needs to be applied, and the locking member 231 is gently toggled to move the positioning protrusion 235 out of the positioning pit. At the same time, the locking member 231 exits the accommodation cavity 211a. When the positioning protrusion 235 exits the positioning pit, the mobile phone 1 can be taken out from the accommodation cavity 211a of the expansion member 21.

[0080] It should be noted that although the positioning protrusion 235 and the positioning pit can provide a firm connection, due to their mechanical engagement design, the user can simply separate the locking member 231 and the expansion member 21 when needed, which is convenient for disassembly and assembly operations. This design retains the flexibility of use while ensuring stability.

[0081] Furthermore, at least two positioning pits and positioning protrusions 235 can be provided, so that a multi-point support is formed between the locking member 231 and the expansion member 21, enhancing the firmness and anti-torsion of the overall connection.

[0082] In some embodiments, the locking member 231 rotates in the installation cavity 210 of the expansion member 21 through a rotating shaft.

[0083] In this embodiment, the locking member 231 is connected to the inner wall of the installation cavity 210 of the expansion member 21 through a rotating shaft, allowing the locking member 231 to perform a rotating action in the installation cavity 210, so as to enter or exit the accommodation cavity 211a by rotation, and then realize the locking and unlocking of the mobile phone 1.

[0084] In some embodiments, the locking component 23 includes a face cover 237 and a detachable connection structure. One side of the face cover 237 is movably connected to the expansion member 21, and the other side of the face cover 237 is detachably connected to the expansion member 21 through the detachable connection structure.

[0085] This design allows the face cover 237 to be combined with the expansion member 21 in a flexible manner, which can not only achieve the movable adjustment of the face cover 237, but also facilitate disassembly and replacement, providing convenience in use and diversity in functions.

[0086] Specifically, one side of the face cover 237 can be connected to the expansion member 21 through a rotating shaft or other movable connection mechanisms, so that the face cover 237 can freely rotate or adjust the angle within a certain range, thereby adapting to different usage requirements or providing a better user experience.

[0087] The other side of the face cover 237 is connected to the expansion member 21 in a detachable manner. This connection method usually includes a quick release mechanism, such as a buckle, a screw or other fixing devices, so that the face cover 237 can be easily detached from the expansion member 21, facilitating cleaning, replacement or personalized customization according to needs.

[0088] In this embodiment, the face cover 237 can protect the mobile phone 1 located in the accommodation cavity 211a and at the same time provide an aesthetic appearance. Through the design of movable connection and detachable connection, users can adjust the position of the face cover 237 or replace different face covers 237 according to needs to meet different usage scenarios or personalized requirements.

[0089] Please refer to Figure 8 , in some embodiments, the detachable connection structure includes a knob 236, a first connection hole 212 provided on the face cover 237, and a second connection hole 213 provided on the expansion member 21 and corresponding to the first connection hole 212. The knob 236 passes through the first connection hole 212 and the second connection hole 213 in sequence to lock the face cover 237 on the expansion member 21.

[0090] Specifically, the knob 236 is a component with a thread or other locking mechanism. It can generate an inward pressure or friction force by rotating, so as to firmly fix the face cover 237 on the expansion member 21. The first connection hole 212 and the second connection hole 213 are pre-designed on the face cover 237 and the expansion member 21 respectively, and are used to guide the knob 236 to pass through and lock the positions of the two.

[0091] When the knob 236 completely passes through these two connection holes, it is usually further tightened by rotation to ensure that the face cover 237 will not accidentally fall off or become loose. This design not only facilitates the assembly and disassembly between the face cover 237 and the expansion member 21.

[0092] In addition, it should be noted that during operation, the knob 236 should be well matched with the first connection hole 212 and the second connection hole 213 to avoid being too tight or too loose. At the same time, when rotating the knob 236, the appropriate force and speed should be maintained to avoid damaging the components or affecting the fixing effect.

[0093] Please refer to Figure 9 In some embodiments, the detachable connection structure includes a first magnetic member 30 disposed on the expansion member 21 and a second magnetic member or magnetic body disposed on the surface cover 237 for magnetically cooperating with the first magnetic member 30 .

[0094] When the cover 237 and the extension piece 21 are close to a certain distance, the magnetic force between the first magnetic member 30 and the second magnetic member (or magnetic body) begins to work. Since the magnetic attraction has the characteristic of automatic alignment, the cover 237 will automatically adjust its position to ensure that the first magnetic member 30 and the second magnetic member (or magnetic body) are aligned and adsorbed. When the two are completely aligned and tightly adsorbed, the cover 237 and the extension piece 21 are stably connected to prevent the mobile phone 1 from easily falling out of the accommodating cavity 211a.

[0095] In this embodiment, the smooth contact surface of the magnetic connection can reduce wear, and the uniform distribution of the magnetic force also avoids local uneven force. Moreover, since the magnetic connection does not rely on a complex snap-on mechanism, the disassembly process is relatively smooth.

[0096] Please refer to Figure 10 In some embodiments, the expansion member 21 is provided with a receiving groove 2101; the detachable connection structure includes a plug-in member 238, a positioning member 239 and a reset member 233, the plug-in member 238 is provided at the movable end of the cover 237, and the plug-in member 238 is provided with a hook portion 2381, and the hook portion 2381 is used to enter or exit the receiving groove 2101 under the action of an external force;

[0097] The positioning member 239 includes a positioning portion 2391 and a control portion 2392. The positioning portion 2391 is disposed in the receiving groove 2101 to engage with the hook portion 2381. The control portion 2392 is connected to the positioning portion 2391. The control portion 2392 is at least partially exposed from the expansion member 21 to move the positioning portion 2391 to engage or separate from the hook portion 2381.

[0098] The restoring member 233 is used to drive the positioning portion 2391 to engage with the hook portion 2381 when the hook portion 2381 enters the receiving groove 2101 and the external force of the control portion 2392 is removed.

[0099] In this embodiment, by providing a hook portion 2381 on the plug-in component 238, the engaging portion 23c can enter or exit the accommodating groove 2101, and the positioning portion 2391 and the hook portion 2381 are engaged and engaged to achieve the engagement and separation of the plug-in component 238 and the positioning component 239, thereby achieving the connection and separation of the cover 237 and the extension component 21. The working principle of the entire structure depends on the movement of the control portion 2392. Under the action of the control portion 2392, the positioning portion 2391 can engage or separate with the hook portion 2381, thereby achieving the engagement and separation of the cover 237 and the extension component 21.

[0100] Since the control part 2392 is exposed on the expansion piece 21, the user can control the engagement and separation of the hook part 2381 and the positioning part 2391 by simply turning the control part 2392, thereby realizing the rapid engagement and separation of the cover 237 and the expansion piece 21. This design not only ensures the stability of the installation, but also improves the convenience of operation.

[0101] When the control part 2392 applies an external force, the reset member 233, through its specific structure and material properties, can withstand and transmit the external force while maintaining the proper positions of the hook part 2381 and the positioning part 2391. Once the external force of the control part 2392 is removed, the reset member 233 can quickly return to its original state, thereby driving the hook part 2381 and the positioning part 2391 to engage, ensuring the stability and reliability of the connection.

[0102] Exemplarily, the reset member 233 may be a compression spring, or a component with specific elastic potential energy such as a spring, which is not limited in the embodiment of the present application.

[0103] Please continue to refer to Figure 1 In some embodiments, the mobile phone expansion component 2 further includes a buffer 22 , and the buffer 22 is detachably connected to the inner wall of the accommodating cavity 211 a , or the buffer 22 is sleeved on the periphery of the mobile phone 1 .

[0104] In this embodiment, the purpose of providing the buffer 22 is to reduce the distance between the mobile phone 1 and the inner wall of the accommodating cavity 211a when the mobile phone 1 is not covered with a mobile phone case. When the mobile phone 1 is matched with the buffer 22 and placed in the accommodating cavity 211a, the two sides of the buffer 22 are respectively in contact with the inner wall of the accommodating cavity 211a and the outer wall of the mobile phone 1, thereby improving the connection stability between the mobile phone 1 and the expansion member 21, preventing the mobile phone 1 without a mobile phone case from loosening when placed in the accommodating cavity 211a, and allowing the mobile phone 1 to be locked by the locking component 23.

[0105] Specifically, the buffer member 22 involves two different connection methods, depending on the design and application scenario of the buffer member 22. When the buffer member 22 is detachably connected to the inner wall of the accommodation cavity 211a, this connection method allows for a tight fit between the buffer member 22 and the accommodation cavity 211a, while facilitating installation and disassembly, as well as maintenance and replacement.

[0106] On the other hand, when the buffer member 22 is sleeved around the periphery of the mobile phone 1, this connection method generally refers to the buffer member 22 being fixed around the periphery of the mobile phone 1 in an inclusive manner, without the need for a complex internal connection structure, and being fixed around the mobile phone 1 through a simple sleeving method, providing additional protection or aesthetic decoration.

[0107] These two connection methods each have their own characteristics and are suitable for different application scenarios and requirements. The detachable connection provides greater flexibility and maintainability, while the sleeving method is simpler and faster, suitable for situations where quick replacement or installation is required. In actual applications, the choice of which method depends on the specific product design requirements and the user's usage habits.

[0108] In this embodiment, on the one hand, if the user's mobile phone 1 is already equipped with a mobile phone case, the user can use the mobile phone expansion component 2 without removing the mobile phone case, which ensures the convenience of the user when using the mobile phone expansion component 2; on the other hand, for users who do not use a mobile phone case, the mobile phone expansion component 2 also provides a buffer member 22 that can be detachably connected to the inner wall of the accommodation cavity 211a or sleeved around the periphery of the mobile phone 1, which enables the smooth use of the mobile phone expansion component 2 even without a mobile phone case, further expanding its scope of application, meeting the usage habits and needs of different users, and making the use of the mobile phone expansion component 2 more convenient.

[0109] Generally speaking, the design of the mobile phone expansion component 2 takes into account the user's usage habits and needs. Whether it is a mobile phone 1 with a mobile phone case installed or a mobile phone 1 without a mobile phone case installed, seamless connection can be achieved through an adapted design and accessories, providing great convenience and flexibility.

[0110] In some embodiments, the buffer member 22 is in a ring structure and is sleeved around the peripheral wall of the mobile phone 1, capable of tightly fitting the peripheral wall of the mobile phone 1 and providing physical protection for the mobile phone 1. Moreover, the ring structure of the buffer member 22 also has an anti-slip effect, capable of preventing the mobile phone 1 from slipping due to hand sweat or moisture. This design improves the comfort of use, especially in humid or sweaty situations, and can keep the mobile phone 1 stable, reducing the risk of accidental dropping.

[0111] In addition, the design of the buffer member 22 also focuses on aesthetics and personalization. Various patterns can be printed on the buffer member 22, which not only increases the aesthetics of the mobile phone 1 but also allows users to select and customize the buffer member 22 according to their preferences, reflecting personalized needs.

[0112] In some embodiments, the material of the buffer member 22 is a soft material, such as silicone, TPU, etc.

[0113] As a preferred embodiment of the present application, the buffer member 22 is made of silicone material. The silicone material is environmentally friendly, healthy, soft and skin-friendly, pollution-free, non-toxic and odorless. It is not easy to deform after processing and has a good hand feeling. The buffer member 22 made of silicone has a smooth surface and will not collide with the mobile phone 1 to cause scratches on the mobile phone 1. Moreover, silicone also has excellent elastic properties and is easy for users to disassemble.

[0114] Among them, the accommodation cavity 211a is used to accommodate the mobile phone 1 with a mobile phone case or the buffer member 22 sleeved thereon, and the locking assembly 23 is used to abut against the end face of the mobile phone case or the buffer member 22 when the mobile phone 1 is placed in the accommodation cavity 211a, so as to avoid the locking assembly 23 directly contacting the screen of the mobile phone 1 and scratching the screen.

[0115] In this embodiment, the design of the accommodation cavity 211a aims to provide a safe and protective environment to protect the mobile phone 1 from damage. By providing an internal space, the mobile phone 1 can be safely placed therein. At the same time, the design of the mobile phone case or the buffer member 22 can also provide additional protection, such as shockproof and scratch-proof functions.

[0116] The embodiment of the present application also provides a photography auxiliary device, including a photography and video shooting auxiliary accessory and a mobile phone expansion component 2. The photography and video shooting auxiliary accessory is detachably connected to the functional interface 211 of the mobile phone expansion component 2.
