[0002] With the widespread use of electronic devices, the demand for locking components in various devices is increasing, especially in the field of charging equipment. Currently, there are many application scenarios requiring locking structures, such as charging devices with replaceable plugs. These devices typically need to meet the plug standards of different countries while ensuring that the plug does not accidentally detach during use.

[0003] Existing locking components are either costly and require continuous power to maintain the locked state, or rely on clips for fixation and a release button for disassembly. These clips and buttons occupy installation space, limiting miniaturization and compromising reliability, resulting in a poor user experience. Therefore, there is an urgent need to design a locking component that is both reliable and cost-effective. Summary of the Invention

[0004] This invention provides a locking component and a charging device to solve the problems of poor reliability and high cost of existing locking components.

The slider is movably inserted into the locking pin and can be movably installed in the locking seat along the first direction, and the opposite ends of the slider are respectively slidably connected to the opposite side walls of the button. Pressing the button causes the slider to move within the locking pin and the locking seat, so that the second end of the locking pin retracts to the locking seat, thus not locking the object to be locked.

The first inclined surface and the second inclined surface are slidably connected.

[0007] Preferably, the angle between the first inclined surface and the surface of the first direction is 30-60 degrees, and the angle between the second inclined surface and the surface of the first direction is 30-60 degrees.

[0008] Preferably, the locking pin includes a pin body portion, a first protrusion extending radially from a first end of the pin body portion, and a locking portion extending axially from a second end of the pin body portion; The main body of the pin passes through the locking seat in the first direction, the first protrusion is located outside the locking seat and is connected to the button through the elastic member. The locking part is used to extend outside the locking seat to lock the object to be locked, or to retract into the locking seat to not lock the object to be locked. The pin body has a through groove in the middle, and the slider is movably inserted into the through groove.

[0009] Preferably, the locking seat includes a first main board, a first support frame extending from the periphery of the first main board in a direction perpendicular to the first main board, and a support post extending from the middle of the first main board in a direction perpendicular to the first main board, wherein the support post is located inside the first support frame. The support column is provided with a movable through hole in the middle direction perpendicular to the first motherboard and a movable through groove in the middle direction parallel to the first motherboard. The button is movably mounted in the first support frame along the first direction, the locking pin passes through the movable through hole along the first direction, and the slider is movably mounted in the movable through groove along the first direction.

[0010] Preferably, the button includes a second motherboard, a second support frame extending from the periphery of the second motherboard in a direction perpendicular to the second motherboard, a second protrusion extending from the middle of the second motherboard in a direction perpendicular to the second motherboard, and two drive blocks disposed on opposite side walls of the second support frame. The second protrusion is located inside the second support frame and is used to support the elastic member; The second support frame is movably installed in the locking seat along the first direction, and the two drive blocks are slidably connected to the opposite ends of the slider.

[0011] A charging device includes a charging body, a charging plug, and a locking assembly; the charging plug is detachably mounted on the charging body. The locking component is mounted on the charging body to lock or not lock the charging plug.

[0012] Preferably, the charging body is provided with a first mounting groove and a second mounting groove, and the groove wall of the first mounting groove is provided with a communicating hole communicating with the second mounting groove; The charging plug is provided with a mounting part, which can be detachably installed in the first mounting slot; The locking assembly is installed in the second mounting groove, and the locking pin of the locking assembly can pass through the communicating hole.

[0013] Preferably, the mounting portion is provided with one or more locking recesses, and the plurality of locking recesses are arranged at intervals along the circumferential direction of the mounting portion; The second end of the locking pin enters either of the locking recesses to lock the mounting portion.

The limiting groove includes a first limiting groove and a second limiting groove arranged sequentially along the axial direction of the mounting part. The first limiting groove is arranged in the circumferential direction, and the second limiting groove is arranged in the axial direction. One end of the second limiting groove is connected to the first limiting groove. The limiting protrusion cooperates with the limiting groove to lock the mounting part into or out of the first mounting groove.

[0015] When the locking assembly provided in this embodiment of the invention is in use, the elastic element, in its natural state, pushes the locking pin outward to form a locking state. When the operator presses the button, the button moves axially to compress the elastic element, and simultaneously, the inclined surface of the button's sidewall contacts both ends of the slider. Under the action of the inclined surface, the slider generates lateral and longitudinal displacement, which is converted into the axial retraction motion of the locking pin through the through-groove inside the locking pin. When the locking pin is fully retracted into the locking seat, the part to be locked is not locked, and the part to be locked is released from constraint and can move freely. After the button is released, the elastic element pushes the button to reset, causing the slider to move in the opposite direction, causing the locking pin to extend again and lock the part to be locked. Compared to existing technologies, this method eliminates the need for continuous power supply to maintain the locked state, reducing costs. The simplified motion conversion mechanism utilizes a transmission structure with inclined contact between the button and slider. The inclined transmission mechanism of the slider converts the movement of the pressed button into the axial displacement of the locking pin, enabling locking position adjustment even in confined spaces and facilitating product miniaturization. The extension and retraction of the locking pin, combined with the button operation, creates a mechanical linkage, ensuring reliable unlocking with each press and avoiding unlocking failures caused by operating angle deviations in traditional structures, thus improving the user experience.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] This utility model provides a locking component, see reference. Figure 1 , Figure 4 , Figure 5 and Figure 6The locking assembly includes a locking seat 1, a button 2, a locking pin 3, an elastic element 4, and a slider 5. The button 2 is movably installed in the locking seat 1 along a first direction, and the locking pin 3 passes through the locking seat 1 along the first direction. The first end of the locking pin 3 is connected to the button 2 through the elastic element 4. Under the action of the elastic element 4, the second end of the locking pin 3 extends out of the locking seat 1 to lock the object to be locked. The slider 5 is movably installed in the locking pin 3 and is movably installed in the locking seat 1 along the first direction. The opposite ends of the slider 5 are slidably connected to the opposite side walls of the button 2. Pressing the button 2 causes the slider 5 to move within the locking pin 3 and the locking seat 1, so that the second end of the locking pin 3 is retracted to the locking seat 1, and the object to be locked is not locked.

[0023] The first direction is the direction of movement of button 2, which can also be described as the axial direction of locking pin 3.

[0024] As an example, the locking assembly includes a locking seat 1, a button 2, a locking pin 3, an elastic element 4, and a slider 5. The locking seat 1 is the base structure supporting the moving parts, which can be implemented using an injection-molded cavity structure, with guide grooves inside to constrain the movement trajectory of the components. The button 2 is a moving part that receives external input and drives other parts through a sidewall slope. The locking pin 3 is a rod-shaped part that performs the locking function, which can be a metal cylinder with a machined inclined groove structure; its axial movement enables the extension and retraction of the locking tongue. The elastic element 4 is an energy storage element that provides restoring force, which can be a helical spring or an elastic pad, connected between the button 2 and the locking pin 3 to generate preload. The slider 5 is a motion conversion component, which can be a metal part or an injection-molded part with an inclined surface; it contacts the button 2 through the inclined surface, causing lateral and longitudinal displacement to change the position of the locking pin 3.

[0025] In this example, when the locking assembly is in use, the elastic element 4, in its natural state, pushes the locking pin 3 outward to form a locking state. When the operator presses button 2, button 2 moves axially to compress the elastic element 4, and simultaneously the inclined surface of the side wall of button 2 contacts both ends of slider 5. Slider 5 generates lateral and longitudinal displacement under the action of the inclined surface, which is converted into the axial retraction movement of locking pin 3 through the through groove 34 inside locking pin 3. When locking pin 3 is fully retracted into locking seat 1, the object to be locked is not locked, and the object to be locked is released from constraint and can move freely. After releasing button 2, the elastic element 4 pushes button 2 to reset, causing slider 5 to move in the opposite direction, causing locking pin 3 to extend again and lock the object to be locked. Compared with existing technologies, this method eliminates the need for continuous power supply to maintain the locked state, reducing costs. The transmission structure utilizing the inclined contact between button 2 and slider 5 simplifies the motion conversion mechanism. The inclined transmission mechanism of slider 5 converts the movement of pressing button 2 into the axial displacement of locking pin 3, enabling locking position adjustment within a confined space and facilitating product miniaturization. The extension and retraction of locking pin 3 and the operation of button 2 form a mechanical linkage, ensuring reliable unlocking with each press and avoiding unlocking failures caused by operating angle deviations in traditional structures, thus improving the user experience.

[0026] In one embodiment, reference is made to Figure 1 The slider 5 includes an inclined body 51 and two connecting arms 52 extending from opposite ends of the inclined body 51 in opposite directions. The inclined body 51 is movably inserted into the locking pin 3 and can be movably installed in the locking seat 1 in the first direction. Each connecting arm 52 has a first inclined surface 53 on its outer side surface that is inclined from the end near the inclined body 51 to the end away from the inclined body 51. The side wall of the button 2 has a second inclined surface that matches the first inclined surface 53. The first inclined surface 53 and the second inclined surface are slidably connected.

[0027] As an example, the inclined body 51 refers to a wedge-shaped structural block with a predetermined angle, the angle of which matches the inclination angle of the through groove 34 inside the locking pin 3, for forming symmetrical support inside the locking pin 3. The connecting arm 52 refers to a block-shaped structure extending in the opposite direction from both ends of the inclined body 51, the extension direction of which forms an angle with the axis of the locking pin 3, for establishing the linkage between the button 2 and the slider 5. The first inclined surface 53 refers to the inclined structure provided on the outer side of the connecting arm 52, which can be achieved by milling, the inclination direction of which forms an angle with the movement direction of the button 2, for converting the movement of the pressed button 2 into the axial displacement of the locking pin 3. The second inclined surface refers to the mating inclined surface provided on the side wall of the button 2, which can be achieved by molding, the inclination angle of which is complementary to the first inclined surface 53, for realizing the force transmission during sliding contact.

[0028] Specifically, when button 2 is pressed, the second inclined surface slides along the first inclined surface 53, forcing the two connecting arms 52 to drive the inclined body 51 to translate along the first direction and move in a direction perpendicular to the first direction. Since the inclined body 51 passes through the inside of the locking pin 3, the movement in the direction perpendicular to the first direction can adaptively adjust the position of the slider 5, providing adaptive space for the inclined sliding contact between the slider 5 and button 2. The translational movement in the first direction pushes the locking pin 3 to retract axially through the through inclined groove 34. In this process, the inclined surfaces of the first and second inclined surfaces cooperate to convert the movement of the pressed button 2 into the axial displacement of the locking pin 3, effectively reducing the operating resistance. The symmetrical arrangement of the two connecting arms 52 creates a balanced force state inside the locking pin 3, avoiding uneven wear caused by unilateral contact. The linear movement path of the inclined body 51 within the locking seat 1 ensures the linear stability of the retraction action of the locking pin 3.

[0029] In this example, by setting complementary inclined surfaces, the frictional resistance of the contact surface is significantly reduced; this achieves effective decomposition and transmission of force during the pressing of button 2, ensuring the smooth retraction of locking pin 3. The bidirectionally extending connecting arm 52 forms a bidirectional symmetrical force transmission structure, eliminating the risk of unilateral wear of parts and extending their service life. The inclined surface design reduces operating resistance, making the unlocking action more effortless and reliable. The precise fit between slider 5 and locking pin 3 ensures the stability of switching between locked and unlocked states. The integrated design of connecting arm 52 and inclined body 51 enhances structural strength and simplifies the assembly process.

[0030] In one embodiment, reference is made to Figure 1 The angle between the plane containing the first inclined plane 53 and the plane containing the first direction is 30-60 degrees, and the angle between the plane containing the second inclined plane and the plane containing the first direction is 30-60 degrees.

[0031] As an example, the first inclined surface 53 refers to the inclined surface located on the outer side of the connecting arm 52 of the slider 5, which can be achieved by machining or injection molding. This inclined surface is used to form a sliding contact with the second inclined surface of the side wall of the button 2. The first direction refers to the direction of movement of the slider 5 within the locking seat 1, which can be defined by providing a guide groove or slide rail. This direction is parallel to the extension and retraction direction of the locking pin 3. The second inclined surface refers to the inclined surface located on the side wall of the button 2, which can be achieved by stamping or milling. This inclined surface cooperates with the first inclined surface 53 to achieve force transmission.

[0032] Specifically, when button 2 is pressed, the second inclined surface moves along the first direction, generating a lateral force through sliding contact with the first inclined surface 53, pushing the slider 5 to move within the locking pin 3. Since the angle between the first inclined surface 53 and the first direction is controlled within the range of 30-60 degrees, specifically 45 degrees, the magnitude of the lateral force is limited to a range sufficient to overcome the resistance of the elastic element 4 and retract the locking pin 3, without causing insufficient travel of the slider 5 due to an excessively small angle. Simultaneously, the second inclined surface uses the same angle range, ensuring continuous contact between the button 2 and the slider 5 during movement, avoiding stress concentration or trajectory deviation due to angle deviation. By limiting the angle range to 30-60 degrees, this application effectively controls the stress distribution of the contact surface while ensuring smooth operation, avoiding localized wear; it achieves optimized matching of the angle between the slider 5 and the button 2 contact surfaces, improving the force transmission efficiency during pressing and making the retraction of the locking pin 3 more stable and reliable. Furthermore, this angle range effectively reduces the sliding friction resistance between the contact surfaces, extending the service life of the locking assembly.

[0033] In one embodiment, reference is made to Figure 1 The locking pin 3 includes a main body 31, a first protrusion 32 extending radially from the first end of the main body 31, and a locking part 33 extending axially from the second end of the main body 31. The main body 31 is inserted into the locking seat 1 in the first direction, the first protrusion 32 is located outside the locking seat 1 and is connected to the button 2 through the elastic member 4. The locking part 33 is used to extend outside the locking seat 1 to lock the object to be locked, or to retract into the locking seat 1 to not lock the object to be locked. The middle part of the main body 31 is provided with a through groove 34, and the slider 5 is movably inserted into the through groove 34.

[0034] As an example, the pin body 31 refers to a columnar structure extending axially, which can be implemented as a cylinder or prism, used to support the overall movement trajectory of the locking pin 3. The first protrusion 32 refers to the part that protrudes radially from the pin body 31, which can be implemented as an annular boss or a partial protrusion, used to form a stable connection interface with the elastic element 4. The locking part 33 refers to the end structure extending axially from the pin body 31, which can be implemented as a conical or columnar head, used to insert into the corresponding recess of the element to be locked. The through groove 34 refers to an inclined groove that penetrates the middle of the pin body 31, specifically a straight inclined groove with an inclination angle of, for example, 30-60 degrees, used to guide the movement direction of the slider 5 and transmit the component force.

[0035] When button 2 is pressed, slider 5 moves within the through-groove 34. Due to the inclination angle of the groove, the movement of slider 5 is decomposed into axial and radial components. The axial component is transmitted to the elastic element 4 through the first protrusion 32, causing it to compress. The radial component adaptively adjusts the position of slider 5, providing space for the inclined sliding contact between slider 5 and button 2, thereby allowing the locking pin 3 to move axially to unlock. When button 2 is released, the elastic element 4 rebounds, pushing the first protrusion 32 back to its original position, and the locking part 33 retracts back into the locking seat 1. The inclination angle of the through-groove 34 is designed to match the movement direction of slider 5, so that the extension and retraction of the locking pin 3 can be completed by pressing button 2 in only one direction.

[0036] In this example, by engaging the slider 5 with the through-slot 34, the axial displacement of the locking pin 3 is directly linked to the linear motion of the slider 5, reducing the number of transmission components. Furthermore, the first protrusion 32 is located outside the locking seat 1, preventing the locking pin 3 from sliding out of the locking seat 1. The connection between the first protrusion 32 and the elastic element 4 avoids the twisting problem of the elastic element 4 caused by traditional axial connections, improving operational stability. The axial extension design of the locking part 33 improves the alignment accuracy with the part to be locked, preventing locking failure due to radial deviation.

[0037] In one embodiment, reference is made to Figure 1 The locking seat 1 includes a first main board 11, a first support frame 12 extending from the periphery of the first main board 11 in a direction perpendicular to the first main board 11, and a support post 13 extending from the middle of the first main board 11 in a direction perpendicular to the first main board 11. The support post 13 is located inside the first support frame 12. The middle part of the support post 13 is provided with a movable through hole 14 arranged in a direction perpendicular to the first main board 11 and a movable through groove 15 arranged in a direction parallel to the first main board 11. The button 2 is movably installed in the first support frame 12 in a first direction, the locking pin 3 passes through the movable through hole 14 in a first direction, and the slider 5 is movably installed in the movable through groove 15 in a first direction.

[0038] As an example, the first support frame 12 refers to an annular frame structure extending from the periphery of the first main board 11 in a direction perpendicular to the first main board 11. It can be integrally constructed using injection molding and serves to guide and limit the linear movement of the button 2. The support column 13 refers to a columnar structure extending from the center of the first main board 11 in a direction perpendicular to the first main board 11. It can be formed using metal insert injection molding and serves to create an independent mounting space for the locking pin 3 and the slider 5 within the annular frame. The movable through hole 14 refers to a circular channel extending axially along the support column 13. It can be formed using CNC machining and serves to constrain the linear movement of the locking pin 3 along the axial direction. The movable slot 15 refers to a strip-shaped channel radially opened along the support column 13. It can be machined using wire cutting and serves to limit the movement trajectory of the slider 5 in the first direction.

[0039] The annular space formed by the first support frame 12 is configured to accommodate the movable component of the button 2. Its inner wall forms a sliding fit with the outer side of the button 2, allowing the button 2 to move linearly only along the first direction. The support column 13 is located in the central area inside the first support frame 12, and its axial through hole forms a clearance fit with the locking pin 3. The locking pin 3 reciprocates along the axis of the through hole under the action of the elastic element 4. The movable through groove 15 is machined in the radial position of the support column 13, and the movement trajectory of the slider 5 is restricted by the two side walls of the through groove to a straight path parallel to the first direction. When the button 2 is pressed and moved, its two side drive blocks 24 push the slider 5 to move along the movable through groove 15 through contact with the inclined surface of the slider 5, thereby causing the locking pin 3 to retract axially within the movable through hole 14. This layered structural design makes the movement trajectories of the button 2, the locking pin 3, and the slider 5 orthogonal in space, effectively avoiding motion interference.

[0040] In this example, by setting the support column 13, a three-dimensional installation structure is formed in three-dimensional space, and the axial movement of the locking pin 3 and the radial movement of the slider 5 are arranged in layers, so that the overall structure achieves a compact layout in the first direction. Through the integrated design of the support column 13 and the first support frame 12, the guiding function of multiple kinematic pairs is realized on a single component. This achieves three-dimensional integrated installation of the locking components in a limited space. The combined structure of the support column 13 and the first support frame 12 forms an inner and outer layered installation space, allowing the button 2, the locking pin 3, and the slider 5 to move independently in the annular area and the central column area, respectively. The perpendicular intersection of the movable through hole 14 and the movable through slot 15 ensures the linear movement accuracy of the locking pin 3 and provides a reliable movement path for the driving action of the slider 5. This spatial layout is particularly suitable for applications in charging equipment where the charging plug 7 is locked, where the installation space is strictly limited. While ensuring the reliability of the movement of each component, it significantly reduces the space occupation of the overall structure.

[0041] In one embodiment, reference is made to Figure 1 The button 2 includes a second main board 21, a second support frame 22 extending from the periphery of the second main board 21 in a direction perpendicular to the second main board 21, a second protrusion 23 extending from the middle of the second main board 21 in a direction perpendicular to the second main board 21, and two drive blocks 24 disposed on opposite side walls of the second support frame 22; the second protrusion 23 is located inside the second support frame 22 and is used to support the elastic member 4; the second support frame 22 is movably installed in the locking seat 1 in a first direction, and the two drive blocks 24 are slidably connected to the opposite ends of the slider 5 respectively.

[0042] As an example, the second main board 21 refers to the base structure of the button 2, which can be implemented using a rectangular metal plate or a plastic plate, and serves as the mounting base for the second support frame 22 and the second protrusion 23. The second support frame 22 refers to a frame structure extending from the periphery of the second main board 21 in a direction perpendicular to the second main board 21, and can be implemented using a U-shaped metal stamping part or an injection molded part. It slides against the inner wall of the locking seat 1, forming a guide structure for the movement of the button 2. The second protrusion 23 refers to a columnar structure protruding from the middle of the second main board 21 in a direction perpendicular to the second main board 21, and can be implemented using a cylindrical metal insert or a plastic boss, used to position the elastic element 4 and transmit elastic force. The drive block 24 refers to the protruding structures located on both sides of the second support frame 22, and can be implemented using a triangular metal slider or a plastic inclined block. It converts the linear movement of the button 2 into the movement of the slider 5 by contacting both ends of the slider 5.

[0043] The second main board 21 serves as the basic load-bearing component, achieving linear guidance of the button 2 through the sliding engagement between the second support frame 22 and the inner wall of the locking seat 1. The second protrusion 23 forms an independent support platform inside the second support frame 22, and the elastic element 4 is stably constrained between the second protrusion 23 and the locking pin 3, avoiding elastic force attenuation due to tilting. Two drive blocks 24 are symmetrically distributed on both sides of the second support frame 22. When the button 2 is pressed and moved, the drive blocks 24 simultaneously contact both ends of the slider 5, pushing the slider 5 to move in the inclined groove inside the locking pin 3 and within the movable through hole 14 of the locking seat 1. This dual-sided drive method ensures that the slider 5 is subjected to balanced force, avoiding jamming caused by unilateral force application. In this example, the independent support structure of the second protrusion 23 enables the elastic element 4 to achieve axial positioning, avoiding elastic force loss due to tilting. At the same time, the design of the dual-sided drive blocks 24 enables the slider 5 to obtain symmetrical driving force, improving transmission efficiency.

[0044] This utility model provides a charging device, see reference. Figures 2-6 It includes a charging body 6, a charging plug 7, and a locking component; the charging plug 7 is detachably mounted on the charging body 6; the locking component is mounted on the charging body 6 to lock or not lock the charging plug 7.

[0045] As an example, the charging body 6 refers to the basic structure that supports the charging plug 7. Specifically, it can be implemented using a housing structure with a mounting groove, providing physical support and positioning for the charging plug 7. The charging plug 7 refers to a replaceable electrical connection component, specifically implemented using a plug base with a locking recess 72, adaptable to different national socket standards through a detachable installation method. The locking assembly refers to a mechanical linkage control device, specifically implemented using a pin-locking mechanism including an elastic element 4 and a slider 5, controlling the fixed state of the charging plug 7 through the extension and retraction of the locking pin 3.

[0046] The charging plug 7 is connected to the charging body 6 via a detachable installation method. The locking pin 3 in the locking assembly is normally extended under the action of the elastic element 4 and is embedded in the locking recess 72 of the charging plug 7 to achieve fixation.

[0047] In this example, the combination of a detachable structure and a dynamic locking component ensures that the charging plug 7 is reliably secured while allowing for optimal insertion angle selection based on the socket layout. The mechanical linkage design of the locking component replaces the simple friction-based fixing method, improving the stability of the plug connection and resolving the issue of the charging plug 7 easily detaching, thus achieving reliable locking of the charging plug 7 onto the charging body 6. The self-resetting characteristic of the locking component ensures that the charging plug 7 remains stable in the locked state, and a pressing operation quickly releases the lock, allowing for the replacement of the charging plug 7.

[0048] In this embodiment, when the charging plug 7 is installed inside the charging body 6, it is pressed down to the bottom and a "click" sound is heard, indicating that the assembly is in place. Using the elastic force of the elastic element 4, the second end of the locking pin 3 extends outside the locking seat 1 to lock the charging plug 7. The button 2 is pressed manually to overcome the elastic force, which drives the slider 5 to move within the locking pin 3 and the locking seat 1, so that the second end of the locking pin 3 is retracted to the locking seat 1 and the charging plug 7 is not locked.

[0049] In one embodiment, reference is made to Figure 3 and Figure 5 The charging body 6 is provided with a first mounting groove 61 and a second mounting groove 62. The groove wall of the first mounting groove 61 is provided with a connecting hole 63 that communicates with the second mounting groove 62. The charging plug 7 is provided with a mounting part 71, which can be detachably installed in the first mounting groove 61. The locking component is installed in the second mounting groove 62, and the locking pin 3 of the locking component can pass through the connecting hole 63.

[0050] As an example, the first mounting groove 61 refers to a recessed structure on the surface of the charging body 6 for accommodating the mounting portion 71 of the charging plug 7. Specifically, it can be implemented using a rectangular or circular groove structure, and its depth can be 1.2-1.5 times the thickness of the mounting portion 71. The second mounting groove 62 refers to a cavity structure adjacent to and independently provided with the first mounting groove 61. Specifically, it can be implemented using a cuboid cavity structure, and its width can be 1.1-1.3 times the overall width of the locking assembly. The connecting hole 63 refers to a channel structure passing through the first mounting groove 61 and the second mounting groove 62. Specifically, it can be implemented using a circular hole with a diameter slightly larger than the outer diameter of the locking pin 3, and the hole wall can be provided with a wear-resistant coating. The mounting portion 71 refers to a protruding structure connecting the end of the charging plug 7 to the charging body 6. Specifically, it can be implemented using a cylindrical boss with a positioning buckle, and its surface can be provided with anti-slip texture.

[0051] When the mounting part 71 is inserted into the first mounting slot 61, the locking assembly is in a ready-to-trigger state within the second mounting slot 62. The locking pin 3, pushed by the elastic element 4, passes through the connecting hole 63 and enters the locking recess 72 of the mounting part 71, forming a physical limit. When the charging plug 7 needs to be replaced, pressing the button 2 drives the slider 5 to move, causing the locking pin 3 to exit the connecting hole 63 and release the limit. The split mounting slot design separates the plug mounting area from the locking assembly, avoiding mechanical interference, improving operational convenience, and achieving functional modularity while maintaining a compact structure. The connecting hole 63 serves as a linkage channel, ensuring the effective stroke of the locking pin 3 while maintaining the structural independence of the two mounting slots, preventing loosening due to accidental triggering, and reducing component wear caused by lateral forces. The mounting part 71 and the first mounting slot 61 are connected in a detachable manner, facilitating quick replacement of the charging plug 7.

[0052] In one embodiment, reference is made to Figure 3 , Figure 5 and Figure 6 The mounting part 71 is provided with one or more locking recesses 72, and the multiple locking recesses 72 are arranged at intervals along the circumferential direction of the mounting part 71; the second end of the locking pin 3 enters into any one of the locking recesses 72 to lock the mounting part 71.

[0053] As an example, the locking recess 72 refers to a groove structure provided on the surface of the mounting part 71 to accommodate the end of the locking pin 3. It can be achieved by stamping or machining, and its depth matches the extension length of the locking pin 3 to achieve effective engagement. The circumferential spacing means that multiple locking recesses 72 are distributed in a ring array around the axis of the mounting part 71, and can be arranged with equal or non-equal angular intervals.

[0054] When the charging plug 7 is installed into the charging body 6, the mounting part 71 is inserted into the first mounting groove 61. The locking pin 3 extends out under the action of the elastic member 4 and enters a locking recess 72 in the mounting part 71. At this time, the charging plug 7 cannot move or rotate axially. When it is necessary to adjust the direction of the charging plug 7, press the button 2 to retract the locking pin 3 and disengage it from the locking recess 72. Then, rotate the charging plug 7 to the target angle and release the button 2. The locking pin 3 will then re-enter the charging plug 7 at the corresponding angle to complete the locking. The circumferential distribution of multiple charging plugs 7 allows the charging plugs 7 to be positioned in different positions within a 360-degree range, enabling selection and fixation of different insertion directions. The cross-sectional shape of the locking recess 72 can be semi-circular, trapezoidal, or rectangular. For example, using a semi-circular recess can reduce the frictional resistance when the locking pin 3 slides. As another embodiment, six locking recesses 72 can be provided on the surface of the mounting part 71, with adjacent recesses spaced 60 degrees apart, forming a six-position adjustable structure.

[0055] This solution utilizes multiple circumferentially distributed locking recesses 72 to effectively lock the charging plug 7 when rotated to any set angle, preventing accidental disengagement due to rotational adjustment and significantly improving locking stability. This application implements a multi-angle locking function for the charging plug 7 on the charging body 6, allowing the charging plug 7 to select the optimal insertion direction based on the socket's spatial position. Simultaneously, a mechanical locking mechanism prevents axial displacement or circumferential rotation of the plug after adjustment. The locking pin 3, in conjunction with different locking recesses 72, forms a multi-position selection structure, ensuring a stable connection even after the charging plug 7's orientation is adjusted.

[0056] In one embodiment, reference is made to Figure 3 The first mounting groove 61 has a limiting protrusion 8 on its groove wall; the mounting part 71 has a limiting groove 73 on its side wall. The limiting groove 73 includes a first limiting groove 731 and a second limiting groove 732 arranged sequentially along the axial direction of the mounting part 71. The first limiting groove 731 is arranged in the circumferential direction, and the second limiting groove 732 is arranged in the axial direction. One end of the second limiting groove 732 is connected to the first limiting groove 731. The limiting protrusion 8 cooperates with the limiting groove 73 to lock the mounting part 71 into or out of the first mounting groove 61.

[0057] As an example, in the design, a limiting protrusion 8 is provided on the groove wall of the first mounting groove 61, and a limiting groove 73 is provided on the side wall of the mounting part 71; by the cooperation of the limiting protrusion 8 and the limiting groove 73, it is easy to quickly install the mounting part 71 in the first mounting groove 61 or remove it from the first mounting groove 61, thereby realizing quick assembly and disassembly between the charging plug 7 and the charging body 6. Specifically, the limiting groove 73 includes a first limiting groove 731 and a second limiting groove 732 arranged sequentially along the axial direction of the mounting part 71. The first limiting groove 731 is arranged in the circumferential direction, and its cross-sectional shape in the axial direction is semi-circular, which can restrict the rotational freedom of the limiting protrusion 8. The second limiting groove 732 is arranged in the axial direction, and its cross-sectional shape in the axial direction is rectangular, which can restrict the axial displacement of the limiting protrusion 8. One end of the second limiting groove 732 is connected to the first limiting groove 731. The first limiting groove 731 and the second limiting groove 732 cooperate to make the limiting groove 73 have an L-shaped structure or a T-shaped structure, which can sequentially restrict the axial displacement and rotational freedom of the limiting protrusion 8, providing multi-directional limiting and improving stability. The limiting protrusion 8 cooperates with the limiting groove 73 to lock the mounting part 71 into or out of the first mounting groove 61. Specifically, during installation, the charging plug 7 and / or the charging body 6 only need to perform two actions: axial movement and circumferential rotation to complete the assembly of the charging plug 7 and the charging body 6. The limiting protrusion 8 sequentially enters the second limiting groove 732 and the first limiting groove 731 to lock the mounting part 71 into the first mounting groove 61. During disassembly, the charging plug 7 and / or the charging body 6 only need to perform two actions: circumferential rotation and axial movement to complete the separation of the charging plug 7 and the charging body 6. When the limiting protrusion 8 sequentially exits the first limiting groove 731 and the second limiting groove 732, the mounting part 71 detaches from the first mounting groove 61. In this example, by cooperating with the limiting protrusion 8, the first limiting groove 731, and the second limiting groove 732, only two actions, axial movement and circumferential rotation, are required to complete the assembly or separation of the charging plug 7 and the charging body 6. This simplifies the assembly process and effectively prevents loosening or shaking between the charging plug 7 and the charging body 6 after installation. This improves the efficiency, stability, and safety of the charging equipment and enhances the user experience.

[0058] In this example, the L-shaped or T-shaped groove provides a guide track for the limiting protrusion 8. The limiting groove 73 and the limiting protrusion 8 achieve self-locking between the charging plug 7 and the charging body 6. When replacing the charging body 6, the user only needs to push / rotate the charging body 6 at a specific angle to complete the installation / removal. This structure is stable and secure, eliminating the risk of shaking or loosening. Eliminating the release button and fixing clips frees up internal space, reducing the size of the charging device and minimizing its footprint without compromising the product's compact design.

[0059] In one embodiment, the first limiting groove 731 is an arc shape arranged in the circumferential direction, and one end of the second limiting groove 732 (specifically, one end of the second limiting groove 732 in the axial direction) is located in the end region or middle region of the first limiting groove 731 in the circumferential direction. In this way, the first limiting groove 731 and the second limiting groove 732 cooperate to make the limiting groove 73 have an L-shaped structure or a T-shaped structure, which can sequentially restrict the axial displacement and rotational degree of freedom of the component, limit in multiple directions, and improve stability. When the limiting groove 73 is L-shaped, the limiting protrusion 8 on the wall of the first mounting groove 61 first enters the second limiting groove 732, and then the charging body 6 is rotated clockwise or counterclockwise so that the limiting protrusion 8 on the wall of the first mounting groove 61 enters the first limiting groove 731 from the second limiting groove 732. When the limiting groove 73 is T-shaped, the limiting protrusion 8 on the wall of the first mounting groove 61 first enters the second limiting groove 732. Whether the charging body 6 is rotated clockwise or counterclockwise, the limiting protrusion 8 on the wall of the first mounting groove 61 can enter the first limiting groove 731 from the second limiting groove 732. This simplifies the assembly process and improves the efficiency, stability and safety of the charging equipment.

[0060] In one embodiment, the number of limiting grooves 73 and limiting protrusions 8 can be selected according to actual needs. There are multiple limiting grooves 73, which are spaced apart in the circumferential direction. There are also multiple limiting protrusions 8, which are spaced apart in the circumferential direction. Each limiting groove 73 is adapted to one limiting protrusion 8. With this configuration, the charging plug 7 and the charging body 6 can be quickly disassembled and assembled through multiple sets of limiting grooves 73 and limiting protrusions 8, so that the connection points between the charging plug 7 and the charging body 6 are evenly distributed, further improving the connection stability.

[0061] The specific assembly and disassembly process in this embodiment is as follows: Align the charging plug 7 with the charging body 6, press it down to the bottom, and then rotate it. A "click" sound indicates that the assembly is complete, and the plug is fixed in place vertically, horizontally, and forward / backward. Press button 2 on the charging body 6 and rotate it in the opposite direction to remove the charging plug 7. This assembly is for the first position. Press button 2 on the charging body 6 again, rotate the charging plug 7, and then release button 2. Another "click" sound indicates the second position. Continue in this manner for the third position.

[0062] A locking recess 72 is added to the mounting portion 71 of the charging plug 7 to facilitate the insertion of the locking pin 3 into the locking recess 72 for locking and securing, ensuring that the charging plug 7 cannot be easily removed. When the locking recess 72 of the charging plug 7 rotates to the corresponding position of the locking pin 3, the locking pin 3 enters the locking recess 72 under the elastic force of the elastic element 4, achieving locking and securing. In its natural state, the elastic element 4 is extended, the slider 5 is at its lowest position, and the locking pin 3 is at its longest position, completing the locking function. Pressing button 2 causes the locking pin 3 to retract inward, and the charging plug 7 can be removed by rotating in the opposite direction. When button 2 is pressed, the force of button 2 on the slider 5 to the left causes the slider 5 to move downward, and then causes the locking pin 3 to move to the right, thereby completing the inward retraction and unlocking function of the locking pin 3.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
