[0002] This application claims priority to Chinese patent application No. 202510118480X, filed on January 24, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of photographic auxiliary equipment technology, and in particular to a power supply handle. Background Technology

[0004] In the field of photography, the grip is an important photographic auxiliary device. It not only provides photographers with a more stable holding experience, but also has a power supply function to meet the power needs of photographic equipment during long shooting sessions.

[0005] However, the power supply handles in related technologies have the following defects in their power supply circuit design: their power supply relies on external power cords for jumper wire connections. This jumper wire method makes the overall appearance of the handle messy. The exposed power cords not only affect the aesthetics of the equipment, but also, in actual use, because photographers often need to move and operate the equipment flexibly, the exposed power cords are very likely to get tangled and pulled by objects in the surrounding environment. This may not only cause wear on the outer sheath of the power cord and breakage of the internal circuits, thus affecting the power supply stability of the photographic equipment and causing shooting interruptions; moreover, once the power cord is damaged, it may also cause safety problems such as short circuits, posing a threat to the safety of the photographic equipment and the user.

[0006] Application content

[0007] The main purpose of this application is to propose a power supply handle that aims to solve the technical problems in related technologies, such as the power supply handle relying on external power cords for connection, which affects the appearance of the handle, the power cord being easy to tangle, and the power supply being unstable due to pulling.

[0008] To achieve the above objectives, this application proposes a power supply handle, comprising:

[0009] The housing has a receiving cavity that can accommodate a power source;

[0010] A power connector is disposed on the housing and electrically connected to the power source;

[0011] A conductive adapter structure includes an adapter housing and a conductive element disposed within the adapter housing. One end of the adapter housing is slidably connected to the outer shell, and the other end is used to connect to a photographic device. One end of the conductive element is electrically connected to the power connector, and the other end is used to electrically connect to the photographic device.

[0012] In some embodiments, the adapter housing and the outer shell are slidably connected by a sliding connection structure, the power connector is disposed along the sliding path of the sliding connection structure, and the conductive element remains electrically connected to the power connector when the adapter housing slides relative to the outer shell.

[0013] In some embodiments, the sliding connection structure includes a slide rail disposed on the outer shell and a slide groove disposed on the adapter housing and adapted to the slide rail, wherein the adapter housing is slidably connected to the outer shell through the slide groove;

[0014] The power connector is arranged along the length of the slide rail, and the conductive element is at least partially exposed outside the adapter housing for electrical connection with the power connector.

[0015] In some embodiments, there are two power connectors, one of which is a positive connector and the other is a negative connector. The positive connector and the negative connector are respectively located on both sides of the slide rail. There are two conductive components corresponding to each other, which are electrically connected to the positive connector and the negative connector respectively.

[0016] In some embodiments, the housing is recessed on at least one side of the slide rail to form a limiting groove, and the power connector is located within the limiting groove;

[0017] The adapter housing is provided with a limiting block that is adapted to the limiting groove, and the conductive element is at least partially exposed outside the limiting block for electrical connection with the power connector in the limiting groove.

[0018] In some embodiments, the adapter housing includes a first connecting shell and a second connecting shell, the first connecting shell being slidably connected to the second connecting shell, the first connecting shell being used to connect to the outer shell, and the second connecting shell being used to connect to the photographic equipment;

[0019] The conductive component includes a first conductive component and a second conductive component, which are respectively disposed on the first connecting shell and the second connecting shell, and are used to achieve electrical connection when the first connecting shell and the second connecting shell are connected and fixed.

[0020] In some embodiments, the first connecting shell is rotatably connected to the second connecting shell via a rotating structure. The rotating structure includes a rotating shaft disposed on one of the first connecting shell and the second connecting shell, and a mounting hole disposed on the other of the first connecting shell and the second connecting shell. The rotating shaft and the mounting hole cooperate to connect the first connecting shell and the second connecting shell.

[0021] In some embodiments, one of the first conductive element and the second conductive element is provided with a conductive disk, and the other is provided with a conductive contact for electrical connection with the conductive disk. The conductive disk is coaxially arranged with the rotation center of the first connecting shell and the second connecting shell.

[0022] In some embodiments, two conductive disks are provided, and the two conductive disks are insulated from each other.

[0023] Both the first conductive element and the second conductive element include a positive conductive element and a negative conductive element. Both positive conductive elements are electrically connected to one of the conductive disks, and both negative conductive elements are electrically connected to the other conductive disk.

[0024] In some embodiments, a locking structure is provided between the outer shell and the adapter housing. The locking structure includes a plurality of locking grooves located on the slide rail and a locking module located on the adapter housing. The locking grooves are spaced apart along the length direction of the slide rail. The locking module is used to form a locking engagement with the locking grooves or to release the locking engagement to lock or unlock the outer shell and the adapter housing.

[0025] In some embodiments, the locking module includes:

[0026] A retaining element that is adapted to the locking groove;

[0027] A retaining member is movably disposed on the adapter housing. The retaining member is used to press against the retaining member to make the retaining member lock into the locking groove or to release the retaining member to make the retaining member release from the locking groove.

[0028] A pressing member is movably disposed on the adapter housing and connected to the abutment member, the pressing member being used to drive the abutment member to move.

A power connector is electrically connected to the power source, responsible for drawing out electrical energy. One end of the adapter housing is slidably connected to the housing, allowing for more flexible adjustment of the adapter housing's position when connecting photographic equipment to accommodate devices of different sizes and shapes. Furthermore, one end of a conductive component within the adapter housing is electrically connected to the power connector, and the other end is electrically connected to the photographic equipment, thus forming a complete power supply circuit and enabling stable power supply to the photographic equipment. Compared to power supply handles in related technologies that rely on external power cords, the power supply handle of this application achieves power supply to the photographic equipment through an internally integrated power source and a conductive component built into the conductive adapter structure, eliminating the need for external wiring. This results in a cleaner and more streamlined overall appearance, significantly improving aesthetics. It also prevents the power cord from becoming tangled or pulled by surrounding objects during use, effectively preventing issues such as wear on the power cord sheath and breakage of internal wiring. This reduces the risk of short circuits caused by damaged power cords, ensuring the safety of both the photographic equipment and the user. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments in this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0042] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0043] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0044] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0045] Please refer to Figures 1 to 3. This application provides a power supply handle 100, which includes a housing 10, a power connector 20, and a conductive adapter structure 30. The housing 10 forms a receiving cavity 102, which can accommodate a power supply 101. The power connector 20 is disposed on the housing 10 and electrically connected to the power supply 101. The conductive adapter structure 30 includes an adapter housing 31 and a conductive element 32 disposed in the adapter housing 31. One end of the adapter housing 31 is slidably connected to the housing 10, and the other end is used to connect to a photographic device. One end of the conductive element 32 is electrically connected to the power connector 20, and the other end is used to electrically connect to the photographic device.

[0046] The power supply handle 100 has a housing 102 inside its outer shell 10. This housing 102 is mainly used to house the power supply 101, such as a lithium battery pack. After the power supply 101 is placed in the housing 102, it is electrically connected to the power supply 101 through the power connector 20 on the outer shell 10, laying the foundation for subsequent power transmission.

[0047] The conductive adapter structure 30 is a crucial component for transmitting electrical energy from the power source 101 to the photographic equipment. One end of the adapter housing 31 is slidably connected to the outer casing 10, allowing for flexible adjustment based on the location and usage scenario of the photographic equipment. The conductive element 32 within the adapter housing 31 is electrically connected at one end to the power connector 20 to obtain electrical energy from the power source 101; the other end is used for electrical connection to the photographic equipment. Once the conductive element 32 is successfully connected to the photographic equipment, electrical energy is transmitted from the power source 101 to the photographic equipment through the conductive element 32, thus powering the photographic equipment.

[0048] Traditional power handles rely on external wiring connections, resulting in a cluttered appearance. However, the power handle 100 of this embodiment utilizes an internal structural design to connect the power supply 101 to the photographic equipment, eliminating exposed power cables and resulting in a clean and aesthetically pleasing overall appearance. In practical use, the absence of exposed power cables prevents them from becoming tangled or pulled by surrounding objects, effectively preventing issues such as wear on the power cable sheath or breakage of internal wiring due to external forces. This ensures the integrity and stability of the power supply line, thereby guaranteeing a stable power supply to the photographic equipment.

[0049] It should be noted that the photographic device can be a mobile phone, camera, etc.; the conductive adapter structure 30 can be clamped onto the photographic device using common clamping structures, which will not be described in detail in this embodiment.

[0050] In some embodiments, the adapter housing 31 and the outer shell 10 are slidably connected by a sliding connection structure 33, the power connector 20 is disposed along the sliding path of the sliding connection structure 33, and the conductive element 32 remains electrically connected to the power connector 20 when the adapter housing 31 slides relative to the outer shell 10.

[0051] The sliding connection structure 33 between the adapter housing 31 and the outer shell 10 is typically based on a slide rail, slide groove, or similar mechanical structure. For example, the slider on the adapter housing 31 cooperates with the slide rail or slide groove on the outer shell 10, allowing the adapter housing 31 to slide smoothly relative to the outer shell 10 along a specific direction (i.e., a sliding path). This provides a basic mechanical movement method for adjusting the position of the adapter housing 31 according to actual needs, enabling the power supply handle 100 to better adapt to photographic equipment of different sizes and installation positions. Users can flexibly adjust the position of the adapter housing 31 according to actual shooting needs and equipment layout to achieve optimal usage.

[0052] The power connector 20 is arranged along the sliding path of the sliding connection structure 33. During the sliding process of the adapter housing 31, the relative position of the power connector 20 and the conductive part 32 is always within the preset connectable range, which avoids the occurrence of accidental power failure due to the change of position of the adapter housing 31. It helps to reduce problems such as electric sparks and increased resistance caused by poor contact, and extends the service life of the power connector 20 and the conductive part 32. At the same time, it can also improve the power transmission efficiency and ensure that the photography equipment receives a stable power supply.

[0053] Please refer to Figures 2 and 5. In some embodiments, the sliding connection structure 33 includes a slide rail 331 disposed on the outer shell 10 and a slide groove 332 disposed on the adapter shell 31 and adapted to the slide rail 331. The adapter shell 31 is slidably connected to the outer shell 10 through the slide groove 332.

[0054] The power connector 20 is arranged along the length of the slide rail 331, and the conductive element 32 is at least partially exposed outside the adapter housing 31 for electrical connection with the power connector 20.

[0055] The slide rail 331 provides a clear path and direction for the sliding of the adapter housing 31, while the slide groove 332 ensures that the adapter housing 31 can fit tightly against the slide rail 331. When an external force is applied to the adapter housing 31, due to the cooperation between the slide groove 332 and the slide rail 331, the adapter housing 31 can only slide along the length direction of the slide rail 331, thus realizing the movable connection of the adapter housing 31 relative to the outer shell 10.

[0056] The power connector 20 is arranged along the length of the slide rail 331, ensuring that the conductive element 32 remains within a contactable range with the power connector 20 as the adapter housing 31 slides along the slide rail 331. The conductive element 32 is at least partially exposed outside the adapter housing 31. When the adapter housing 31 slides, the exposed conductive element 32 contacts the power connector 20, thus forming an electrical connection. This design utilizes the layout relationship between the sliding path and the electrical connection components to ensure a stable electrical connection even when the position of the adapter housing 31 changes.

[0057] In this embodiment, the power connector 20 is arranged along the length of the slide rail 331. During the sliding process of the adapter housing 31, the conductive element 32 can maintain a continuous electrical connection with the power connector 20, avoiding power outages caused by position changes and providing a stable power supply for the photography equipment.

[0058] In addition, the layout of the sliding connection structure 33 and the electrical connection structure in this embodiment works together to make full use of the space between the outer shell 10 and the adapter shell 31, making the structure of the entire power supply handle 100 more compact and smaller in size, making it easier to carry and use. It also reduces external connection parts and lines, improving the integration and overall performance of the product.

[0059] Please refer to Figure 4. In some embodiments, there are two power connectors 20, one of which is a positive connector 21 and the other is a negative connector 22. The positive connector 21 and the negative connector 22 are respectively located on both sides of the slide rail 331. There are two conductive components 32, which are electrically connected to the positive connector 21 and the negative connector 22 respectively.

[0060] In this circuit, the positive connector 21 is connected to the positive terminal of the power supply 101, and the negative connector 22 is connected to the negative terminal of the power supply 101. The positive and negative connectors 21 and 22 are located on both sides of the slide rail 331. One end of each of the two corresponding conductive elements 32 on the adapter housing 31 remains in contact with the positive and negative connectors 21 and 22 during sliding, while the other end is connected to the photographic equipment. In this way, the power supply 101, the power connector 20, the conductive elements 32, and the photographic equipment constitute a complete circuit, enabling the transmission of electrical energy from the power supply 101 to the photographic equipment.

[0061] In this embodiment, the positive terminal connector 21 and the negative terminal connector 22 are respectively located on both sides of the slide rail 331, increasing the distance between them and reducing the possibility of short circuits between the positive and negative terminals caused by foreign objects, dust, etc., thereby improving the safety of the power supply system. During the sliding process of the adapter housing 31, the design of the distribution on both sides allows the conductive component 32 to make more stable contact with the corresponding power connector 20, reducing poor contact caused by shaking or vibration, and ensuring a stable power supply for the photographic equipment.

[0062] In some embodiments, the housing 10 is recessed on at least one side of the slide rail 331 to form a limiting groove 11, and the power connector 20 is located in the limiting groove 11.

[0063] The adapter housing 31 is provided with a limiting block 311 that is adapted to the limiting groove 11. The conductive element 32 is at least partially exposed outside the limiting block 311 for electrical connection with the power connector 20 in the limiting groove 11.

[0064] When the adapter housing 31 slides on the slide rail 331 of the outer shell 10 via the slide groove 332, the limiting block 311 will be embedded in the limiting groove 11. The limiting groove 11 provides lateral and longitudinal constraints on the limiting block 311, limiting unnecessary shaking and offset that may occur during the sliding process of the adapter housing 31, ensuring that the adapter housing 31 can only slide in a straight line along the direction of the slide rail 331, making the sliding process more stable and precise.

[0065] The power connector 20 is located within the limiting groove 11, and the conductive element 32 is at least partially exposed outside the limiting block 311. Thus, during the process of the limiting block 311 being inserted into the limiting groove 11, the conductive element 32 exposed outside the limiting block 311 will naturally contact the power connector 20 within the limiting groove 11, thereby forming an electrical connection. Because the cooperation between the limiting groove 11 and the limiting block 311 ensures the stability of the sliding of the adapter housing 31, it also ensures that the conductive element 32 and the power connector 20 can maintain a continuous and stable electrical connection, realizing the transmission of electrical energy from the power supply 101 to the photographic equipment.

[0066] In this embodiment, the power connector 20 is placed within the limiting groove 11, making full use of the internal space of the housing 10 and resulting in a more compact structure for the entire power supply handle 100. This design integrates mechanical limiting and electrical connection functions without increasing the overall size, thus improving the product's space utilization. Furthermore, the limiting groove 11 provides some protection for the power connector 20, reducing the impact of external factors (such as dust and moisture) on it. Simultaneously, the stable electrical connection reduces friction and wear between the conductive component 32 and the power connector 20, extending their service life.

[0067] Please refer to Figures 2 and 5. The adapter housing 31 includes a first connecting housing 312 and a second connecting housing 313. The first connecting housing 312 and the second connecting housing 313 are slidably connected. The first connecting housing 312 is used to connect with the outer housing 10, and the second connecting housing 313 is used to connect with the photographic equipment.

[0068] The conductive element 32 includes a first conductive element 321 and a second conductive element 322. The first conductive element 321 and the second conductive element 322 are respectively disposed on the first connecting shell 312 and the second connecting shell 313, and are used to realize electrical connection when the first connecting shell 312 and the second connecting shell 313 are connected and fixed.

[0069] The adapter housing 31 consists of a first connecting shell 312 and a second connecting shell 313, which are slidably connected, allowing the first connecting shell 312 and the second connecting shell 313 to move relative to each other along a preset path. The first connecting shell 312 is connected to the outer shell 10, while the second connecting shell 313 is used to connect the photographic equipment. When it is necessary to adjust the relative position of the photographic equipment and the outer shell 10 (where the power supply 101 is located), this can be achieved by sliding the first connecting shell 312 and the second connecting shell 313, while also allowing them to be connected and fixed in a suitable position.

[0070] The conductive element 32 is divided into a first conductive element 321 and a second conductive element 322, which are respectively installed on the first connecting shell 312 and the second connecting shell 313. When the first connecting shell 312 and the second connecting shell 313 slide to the appropriate position and are connected and fixed, the first conductive element 321 and the second conductive element 322 come into contact with each other, thereby achieving an electrical connection. In this way, the electrical energy of the power supply 101 can be transmitted to the photographic equipment in sequence through the power connector 20 on the outer shell 10, the first conductive element 321, and the second conductive element 322, ultimately supplying power to the photographic equipment.

[0071] During photography, the position of the camera equipment may need to be adjusted based on factors such as shooting angle and distance. The sliding connection design of the first connecting shell 312 and the second connecting shell 313 allows users to easily change the relative position between the camera equipment and the power supply 101 to adapt to various complex shooting scenarios. Furthermore, the first conductive element 321 and the second conductive element 322 achieve electrical connection when the first connecting shell 312 and the second connecting shell 313 are fixed together, ensuring stable power transmission even after position adjustments and effectively preventing power outages or poor contact caused by position changes.

[0072] Please refer to Figures 3, 5 and 6. In some embodiments, the first connecting shell 312 is rotatably connected to the second connecting shell 313 via a rotating structure 316. The rotating structure 316 includes a rotating shaft 314 disposed in one of the first connecting shell 312 and the second connecting shell 313, and a mounting hole 315 disposed in the other of the first connecting shell 312 and the second connecting shell 313. The rotating shaft 314 and the mounting hole 315 cooperate to connect the first connecting shell 312 and the second connecting shell 313.

[0073] The rotating structure 316 achieves a stable and reliable connection between the first connecting shell 312 and the second connecting shell 313 by respectively providing a rotating shaft 314 and a mounting hole 315. Specifically, the rotating shaft 314 is precisely embedded into the corresponding mounting hole 315, forming a shaft-hole mating structure, allowing the first connecting shell 312 and the second connecting shell 313 to rotate relative to each other around the centerline of the rotating shaft 314. This rotating structure 316 is relatively simple, has an uncomplicated manufacturing process, and low cost. At the same time, the installation process is also convenient, improving production efficiency.

[0074] This embodiment connects the first connecting shell 312 and the second connecting shell 313 via a rotating structure 316, enabling the camera device connected to the second connecting shell 313 to be adjusted at multiple angles. During shooting, the user can adjust the shooting angle of the camera device according to actual needs, such as shooting from above or below, to obtain the desired shooting effect.

[0075] In some embodiments, one of the first conductive element 321 and the second conductive element 322 is provided with a conductive disk 323, and the other is provided with a conductive contact 324 for electrical connection with the conductive disk 323. The conductive disk 323 is coaxially arranged with the rotation center of the first connecting shell 312 and the second connecting shell 313.

[0076] The circular structure of the conductive disk 323 provides a continuous, omnidirectional contact area for the conductive contact 324. Specifically, since the conductive disk 323 is coaxial with the rotation centers of the first connecting shell 312 and the second connecting shell 313, the conductive contact 324 can always maintain contact with the conductive disk 323 regardless of how the first connecting shell 312 and the second connecting shell 313 rotate relative to each other. This ensures that electrical signals or electrical energy can be stably transmitted between the two conductive components 32, avoiding power outages caused by angle changes and ensuring the smooth progress of the shooting process.

[0077] In this embodiment, the coaxial arrangement of the rotation centers of the conductive disk 323, the first connecting shell 312, and the second connecting shell 313 makes the contact between the conductive contact 324 and the conductive disk 323 more uniform and stable. During rotation, the sliding trajectory of the conductive contact 324 on the surface of the conductive disk 323 is relatively fixed, reducing poor contact phenomena such as electric sparks and increased resistance caused by unstable contact. This not only helps to extend the service life of the conductive component 32, but also improves the efficiency and stability of power transmission, ensuring the normal operation of the photographic equipment.

[0078] In addition, the conductive disk 323 is coaxially arranged with the rotation center, utilizing the central space of the rotating structure 316, so that the electrical connection structure and the mechanical rotating structure 316 are tightly integrated and do not interfere with each other. This layout makes full use of the limited space of the adapter housing 31, making the structure of the entire adapter housing 31 more compact, and achieving effective integration of rotation function and stable electrical connection function without increasing the volume too much.

[0079] In some embodiments, two conductive disks 323 are provided, and the two conductive disks 323 are insulated from each other;

[0080] Both the first conductive element 321 and the second conductive element 322 include a positive conductive element 32 and a negative conductive element 32. The two positive conductive elements 32 are electrically connected to one of the conductive disks 323, and the two negative conductive elements 32 are electrically connected to the other conductive disk 323.

[0081] The conductive disks 323, each with corresponding positive and negative terminals, ensure that the currents at the positive and negative terminals are transmitted independently without interference. The positive current of the power supply 101 flows from the positive conductive element 32 of the first conductive element 321 into a connected conductive disk 323, and then through this conductive disk 323 to the positive conductive element 32 of the second conductive element 322, ultimately reaching the positive terminal of the photographic equipment. Similarly, the negative current of the power supply 101 flows from the negative conductive element 32 of the first conductive element 321 into another conductive disk 323, and then through the negative conductive element 32 of the second conductive element 322, returning to the negative terminal of the power supply 101, thus forming a complete current loop to continuously power the photographic equipment.

[0082] In this embodiment, the two conductive disks 323 are insulated from each other, effectively preventing short circuits between the positive and negative terminals from a physical structure perspective. Even during the rotation of the first connecting shell 312 and the second connecting shell 313, the positive and negative terminals will not accidentally come into contact due to the relative movement of the components, ensuring the safety and stability of the entire power supply system.

[0083] Please refer to Figures 2 and 7. In some embodiments, a locking structure 40 is provided between the outer shell 10 and the adapter shell 31. The locking structure 40 includes a plurality of locking grooves 41 located on the slide rail 331 and a locking module 42 located on the adapter shell 31. The locking grooves 41 are spaced apart along the length direction of the slide rail 331. The locking module 42 is used to form a locking engagement with the locking grooves 41 or to cancel the locking engagement to lock or unlock the outer shell 10 and the adapter shell 31.

[0084] When it is necessary to lock the outer shell 10 and the adapter shell 31, the locking module 42 will cooperate with the locking groove 41 on the slide rail 331. The locking module 42 can be aligned and embedded in the locking groove 41 under a certain external force, thereby achieving a tight clamping between the two, fixing the outer shell 10 and the adapter shell 31 relatively, restricting their relative movement in the direction of the slide rail 331, and achieving the purpose of locking.

[0085] When unlocking is required, an external force is applied to the locking module 42 in the opposite direction to that used for locking, causing the locking module 42 to move accordingly, thereby disengaging from the locking groove 41, releasing the locking state between the two, and allowing relative sliding operations between the outer shell 10 and the adapter shell 31 to achieve unlocking.

[0086] In this embodiment, multiple locking grooves 41 are spaced apart along the length of the slide rail 331, providing multiple precise positioning points for the outer shell 10 and the adapter housing 31. During installation or use, the outer shell 10 and the adapter housing 31 can be accurately locked in predetermined positions, ensuring the relative positional accuracy between them, which is beneficial to ensuring the assembly accuracy and performance of the entire device. Moreover, the design of multiple locking grooves 41 allows the outer shell 10 and the adapter housing 31 to be locked in different positions according to actual needs, providing good flexibility and meeting the different requirements for the relative position of the two in different usage scenarios, thus improving the versatility and adaptability of the product.

[0087] Please continue to refer to Figure 7. In some embodiments, the locking module 42 includes a retaining member 421, a supporting member 422, and a pressing member 423. The retaining member 421 is adapted to the locking groove 41. The supporting member 422 is movably disposed on the adapter housing 31. The supporting member 422 is used to press against the retaining member 421 to make the retaining member 421 lock into the locking groove 41 or to release the retaining member 421 to make the retaining member 421 release from the locking groove 41. The pressing member 423 is movably disposed on the adapter housing 31 and connected to the supporting member 422. The pressing member 423 is used to drive the supporting member 422 to move.

[0088] The shape and size of the retaining member 421 are precisely matched with the locking groove 41. The retaining member 421 can be a columnar or block structure with a certain elasticity. It can be tightly embedded in the locking groove 41 under the action of the retaining member 422 to achieve a reliable locking effect and prevent the movement of the adapter housing 31.

[0089] The abutment 422 can be a slider structure or a push rod structure, which contacts the retaining member 421 and changes the state of the retaining member 421 by its own movement. When the abutment 422 moves in the direction that makes the retaining member 421 clamp, it can apply sufficient pressure to the retaining member 421 to force the retaining part of the retaining member 421 to be firmly engaged in the locking groove 41; and when the abutment 422 moves in the opposite direction, it can release the pressure on the retaining member 421 so that the retaining member 421 is released from the locking groove 41. The moving track of the abutment 422 on the adapter housing 31 can be a linear guide or a dovetail groove structure to ensure the smoothness and directionality of its movement.

[0090] The pressing member 423 is movably disposed on the adapter housing 31 and connected to the supporting member 422. It is a direct component for the user to operate the locking module 42. When the user presses the pressing member 423, the pressing member 423 can transmit the pressing force to the supporting member 422, causing the supporting member 422 to move in a predetermined direction, thereby causing the supporting member 422 to release the holding member 421.

[0091] In this embodiment, the fitting design of the retaining member 421 and the locking groove 41, as well as the supporting action of the abutting member 422 on the retaining member 421, ensure that the adapter housing 31 will not easily shift when locked. The setting of the pressing member 423 allows the user to achieve the locking and unlocking functions through simple manual operation, without the need for complicated tools or cumbersome operation steps.

[0092] In some embodiments, the pressing member 423, the supporting member 422, and the holding member 421 are arranged sequentially along the height direction of the adapter housing 31, and the moving direction of the pressing member 423 is different from the moving direction of the supporting member 422.

[0093] The pressing member 423 is provided with a guide groove 4231, and the supporting member 422 is provided with a guide post 4221. The guide post 4221 is inserted into the guide groove 4231. When the pressing member 423 moves, the guide post 4221 is driven to move along the guide groove 4231, so as to drive the supporting member 422 to move.

[0094] In this embodiment, the pressing member 423, the supporting member 422, and the locking member 421 are arranged sequentially along the height direction of the adapter housing 31. This layout makes full use of the space of the adapter housing 31 in the height direction, making the locking module 42 structure more compact and convenient to operate.

[0095] Furthermore, the direction of movement of the pressing member 423 is different from that of the supporting member 422. For example, the pressing member 423 can be designed to move along a horizontal first direction, while the supporting member 422 moves along a horizontal second direction, which is perpendicular to the first direction. This design can better adapt to the internal structural layout of the adapter housing 31, avoid mutual interference between the movement trajectories of the components, and also help to effectively convert the pressing force into a locking force on the holding member 421.

[0096] The pressing member 423 and the supporting member 422 are linked by a guide groove 4231 and a guide post 4221. When the pressing member 423 moves, the guide post 4221 is driven to move along the guide groove 4231 under the oblique constraint of the guide groove 4231. Due to the inclined characteristics of the guide groove 4231, the movement of the guide post 4221 will cause the supporting member 422 to produce a displacement in a different direction than that of the pressing member 423, ultimately causing the holding member 421 to lock or release the locking groove 41. The inclination angle of the guide groove 4231 can be set according to actual needs, which will not be described in detail here.

[0097] The locking module 42, through its component layout along the height direction of the adapter housing 31 and the linkage structure of the guide groove 4231 and the guide post 4221, achieves a reasonable arrangement and efficient linkage of various components within a limited space, reducing the overall volume of the locking module 42 and contributing to the compact design of the overall structure of the adapter housing 31. Furthermore, the cooperation between the guide groove 4231 and the guide post 4221 accurately converts the movement of the pressing member 423 in the first direction into the movement of the holding member 422 in the second direction, thereby precisely controlling the locking and unlocking actions of the holding member 421 and improving the operational accuracy and reliability of the locking module 42.

[0098] In some embodiments, the side of the abutment member 422 facing the retaining member 421 is the abutment surface 4222, and the abutment surface 4222 is recessed with a relief groove 4223. The abutment member 422 can be moved to switch positions to abut against the retaining member 421 through the abutment surface 4222 or to avoid the retaining member 421 through the relief groove 4223.

[0099] In this embodiment, the abutment surface 4222 of the abutment member 422 is the key part that directly contacts and transmits force with the retaining member 421. The abutment surface 4222 is recessed with a relief groove 4223, the shape and size of which are adapted to the local structure of the retaining member 421. For example, the relief groove 4223 can be rectangular, arc-shaped, or other geometric shapes. When the abutment member 422 is in the locked position, the abutment surface 4222 is in close contact with the retaining member 421, and the retaining member 421 is stably held in the locking groove 41 by abutting the retaining member 421. When unlocking is required, the abutment member 422 moves to switch positions, so that the relief groove 4223 is aligned with the retaining member 421. At this time, the retaining member 421 can move freely in the relief groove 4223 or break away from the close contact with the abutment member 422 under the action of other factors, thereby realizing the transition from the locked state to the unlocked state.

[0100] The design of the abutment surface 4222 and the relief groove 4223 on the abutment member 422 enables it to provide a stable abutment force for the holding member 421 when locked, ensuring the reliability of the lock, and to quickly release the constraint on the holding member 421 when unlocked through the ingenious setting of the relief groove 4223, realizing a convenient unlocking operation, which greatly improves the efficiency and flexibility of the locking module 42.

[0101] In some embodiments, the adapter housing 31 is provided with a receiving cavity 310, a retaining member 421 protrudes from the cavity wall of the receiving cavity 310, and a pressing member 423 at least partially protrudes from the outer surface of the conductive adapter structure 30.

[0102] The retaining member 421 protrudes from the cavity wall of the receiving cavity 310. Its protruding portion has a specific shape and size, and is used to cooperate with the locking groove 41 on the housing 10 to achieve the locking function. The position of the retaining member 421 on the cavity wall is determined according to the locking position requirements of the housing 10, and is not limited here. The pressing member 423 at least partially protrudes from the outer surface of the adapter housing 31 so that the operator can easily access and press it.

[0103] The above embodiments of this application are merely examples for clear illustration and are not intended to limit the implementation of this application. Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of this application are still within the protection scope of this application.
